EXPLANATORY NOTE
This report combines the Annual Reports on Form 10-K for the fiscal year ended December 31, 2019 of Boston Properties, Inc. and Boston Properties Limited Partnership. Unless stated otherwise or the context otherwise requires, references to “BXP” mean Boston Properties, Inc., a Delaware corporation and real estate investment trust (“REIT”), and references to “BPLP” and the “Operating Partnership” mean Boston Properties Limited Partnership, a Delaware limited partnership. BPLP is the entity through which BXP conducts substantially all of its business and owns, either directly or through subsidiaries, substantially all of its assets. BXP is the sole general partner and also a limited partner of BPLP. As the sole general partner of BPLP, BXP has exclusive control of BPLP’s day-to-day management. Therefore, unless stated otherwise or the context requires, references to the “Company,” “we,” “us” and “our” mean collectively BXP, BPLP and those entities/subsidiaries consolidated by BXP.
As of December 31, 2019, BXP owned an approximate 89.6% ownership interest in BPLP. The remaining approximate 10.4% interest was owned by limited partners. The other limited partners of BPLP are (1) persons who contributed their direct or indirect interests in properties to BPLP in exchange for common units or preferred units of limited partnership interest in BPLP and/or (2) recipients of long-term incentive plan units of BPLP pursuant to BXP’s Stock Option and Incentive Plans. Under the limited partnership agreement of BPLP, unitholders may present their common units of BPLP for redemption at any time (subject to restrictions agreed upon at the time of issuance of the units that may restrict such right for a period of time, generally one year from issuance). Upon presentation of a common unit for redemption, BPLP must redeem the unit for cash equal to the then value of a share of BXP’s common stock. In lieu of a cash redemption by BPLP, however, BXP may elect to acquire any common units so tendered by issuing shares of BXP common stock in exchange for the common units. If BXP so elects, its common stock will be exchanged for common units on a one-for-one basis. This one-for-one exchange ratio is subject to specified adjustments to prevent dilution. BXP generally expects that it will elect to issue its common stock in connection with each such presentation for redemption rather than having BPLP pay cash. With each such exchange or redemption, BXP’s percentage ownership in BPLP will increase. In addition, whenever BXP issues shares of its common stock other than to acquire common units of BPLP, BXP must contribute any net proceeds it receives to BPLP and BPLP must issue to BXP an equivalent number of common units of BPLP. This structure is commonly referred to as an umbrella partnership REIT, or UPREIT.
The Company believes that combining the Annual Reports on Form 10-K of BXP and BPLP into this single report provides the following benefits:
enhances investors’ understanding of BXP and BPLP by enabling investors to view the business as a whole in the same manner as management views and operates the business;
eliminates duplicative disclosure and provides a more concise and readable presentation because a substantial portion of the disclosure applies to both BXP and BPLP; and
creates time and cost efficiencies through the preparation of one combined report instead of two separate reports.
The Company believes it is important to understand the few differences between BXP and BPLP in the context of how BXP and BPLP operate as a consolidated company. The financial results of BPLP are consolidated into the financial statements of BXP. BXP does not have any other significant assets, liabilities or operations, other than its investment in BPLP, nor does it have employees of its own. BPLP, not BXP, generally executes all significant business relationships other than transactions involving the securities of BXP. BPLP holds substantially all of the assets of BXP, including ownership interests in joint ventures. BPLP conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for the net proceeds from equity offerings by BXP, which are contributed to the capital of BPLP in exchange for common or preferred units of partnership in BPLP, as applicable, BPLP generates all remaining capital required by the Company’s business. These sources include working capital, net cash provided by operating activities, borrowings under its credit facilities, the issuance of secured and unsecured debt and equity securities and proceeds received from the disposition of certain properties and interests in joint ventures.
Shareholders’ equity, partners’ capital and noncontrolling interests are the main areas of difference between the consolidated financial statements of BXP and BPLP. The limited partners of BPLP are accounted for as partners’ capital in BPLP’s financial statements and as noncontrolling interests in BXP’s financial statements. The noncontrolling interests in BPLP’s financial statements include the interests of unaffiliated partners in various consolidated partnerships. The noncontrolling interests in BXP’s financial statements include the same



noncontrolling interests at BPLP’s level and limited partners of BPLP. The differences between shareholders’ equity and partners’ capital result from differences in the equity issued at BXP and BPLP levels.
In addition, the consolidated financial statements of BXP and BPLP differ in total real estate assets resulting from previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor redemptions of common units of BPLP. This accounting resulted in a step-up of the real estate assets at BXP. This resulted in a difference between the net real estate of BXP as compared to BPLP of approximately $291.3 million, or 1.7% at December 31, 2019, and a corresponding difference in depreciation expense, impairment losses and gains on sales of real estate upon the sale of certain properties having an allocation of the real estate step-up. The acquisition accounting was nullified on a prospective basis beginning in 2009 as a result of the Company’s adoption of a new accounting standard requiring any future redemptions to be accounted for solely as an equity transaction.
To help investors better understand the key differences between BXP and BPLP, certain information for BXP and BPLP in this report has been separated, as set forth below:

PART I

Item 1. Business

General
BXP, a Delaware corporation organized in 1997, is a fully integrated, self-administered and self-managed real estate investment trust, or “REIT,” and the largest publicly-traded office REIT (based on total market capitalization) as of December 31, 2019 in the United States that develops, owns and manages primarily Class A office properties.
Our properties are concentrated in five markets—Boston, Los Angeles, New York, San Francisco and Washington, DC. At December 31, 2019, we owned or had interests in 196 commercial real estate properties, aggregating approximately 52.0 million net rentable square feet of primarily Class A office properties, including 11 properties under construction/redevelopment totaling approximately 5.5 million net rentable square feet. As of December 31, 2019 our properties consisted of:
 
177 office properties (including nine properties under construction/redevelopment);
twelve retail properties;
six residential properties (including two properties under construction); and
one hotel.
We consider Class A office properties to be well-located buildings that are professionally managed and maintained, attract high-quality tenants and command upper-tier rental rates, and that are modern structures or have been modernized to compete with newer buildings. Our definition of Class A office properties may be different than those used by other companies.
We are a full-service real estate company, with substantial in-house expertise and resources in acquisitions, development, financing, capital markets, construction management, property management, marketing, leasing, accounting, risk management, tax and legal services. BXP manages BPLP as its sole general partner. As of December 31, 2019, we had approximately 760 employees. Our 35 senior officers have an average of 32 years of experience in the real estate industry, including an average of 21 years of experience with us. Our principal executive office and Boston regional office are located at The Prudential Center, 800 Boylston Street, Suite 1900, Boston, Massachusetts 02199 and our telephone number is (617) 236-3300. In addition, we have regional offices at 2400 Broadway, Suite 510, Santa Monica, California 90404, 599 Lexington Avenue, New York, New York 10022, Four Embarcadero Center, San Francisco, California 94111 and 2200 Pennsylvania Avenue NW, Washington, DC 20037.

On our website, you can obtain free copies of our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the Securities and Exchange Commission, or the SEC. You may also obtain BXP’s and BPLP’s reports by accessing the EDGAR database at the SEC’s website at http://www.sec.gov, or we will furnish an electronic or paper copy of these reports free of charge upon written request to: Investor Relations, Boston Properties, Inc., Prudential Center, 800 Boylston Street, Suite 1900, Boston, Massachusetts 02199. “Boston Properties” is a registered trademark and the “bxp” logo is a trademark, in both cases, of BPLP.
Boston Properties Limited Partnership
BPLP is a Delaware limited partnership organized in 1997, and the entity through which BXP conducts substantially all of its business and owns, either directly or through subsidiaries, substantially all of its assets. BXP is the sole general partner of BPLP and, as of February 21, 2020, the owner of approximately 89.6% of the economic interests in BPLP. Economic interest was calculated as the number of common partnership units of BPLP owned by BXP as a percentage of the sum of (1) the actual aggregate number of outstanding common partnership units of BPLP, (2) the number of common units issuable upon conversion of all outstanding long term incentive plan units of BPLP, or LTIP Units, other than LTIP Units issued in the form of Multi-Year Long-Term Incentive Plan Awards (“MYLTIP Awards”) that remain subject to performance conditions, assuming all conditions have been met for the conversion of the LTIP Units, (3) the 2012 Outperformance Awards that were issued in the form of LTIP Units and earned as of February 6, 2015 (the “2012 OPP Units”), (4) the 2013 MYLTIP Units that were issued in the form of LTIP Units and earned as of February 4, 2016 (the “2013 MYLTIP Units”), (5) the 2014 MYLTIP Units that were issued in the form of LTIP Units and earned as of February 3, 2017 (the “2014 MYLTIP Units”), (6)

1


the 2015 MYLTIP Units that were issued in the form of LTIP Units and earned as of February 4, 2018 (the “2015 MYLTIP Units”), (7) the 2016 MYLTIP Units that were issued in the form of LTIP Units and earned as of February 9, 2019 (the “2016 MYLTIP Units”) and (8) the 2017 MYLTIP Units that were issued in the form of LTIP Units and earned as of February 6, 2020 (the “2017 MYLTIP Units”). An LTIP Unit is generally the economic equivalent of a share of BXP’s restricted common stock, although LTIP Units issued in the form of MYLTIP Awards are only entitled to receive one-tenth (1/10th) of the regular quarterly distributions (and no special distributions) prior to being earned. BXP’s general and limited partnership interests in BPLP entitles BXP to share in cash distributions from, and in the profits and losses of, BPLP in proportion to BXP’s percentage interest and entitles BXP to vote on all matters requiring a vote of the limited partners.
Preferred units of BPLP have the rights, preferences and other privileges set forth in an amendment to the limited partnership agreement of BPLP. As of December 31, 2019 and February 21, 2020, BPLP had one series of Preferred Units outstanding consisting of 80,000 Series B Preferred Units. The Series B Preferred Units have a liquidation preference of $2,500 per share (or an aggregate of approximately $193.6 million at December 31, 2019 and February 21, 2020, after deducting the underwriting discount and transaction expenses). The Series B Preferred Units were issued by BPLP on March 27, 2013 in connection with BXP’s issuance of 80,000 shares (8,000,000 depositary shares each representing 1/100th of a share) of 5.25% Series B Cumulative Redeemable Preferred Stock (the “Series B Preferred Stock”). BXP contributed the net proceeds from the offering to BPLP in exchange for Series B Preferred Units having rights, performance and privileges generally mirroring those of the Series B Preferred Stock. BXP will pay cumulative cash dividends on the Series B Preferred Stock at a rate of 5.25% per annum of the $2,500 liquidation preference per share. On and after March 27, 2018, BXP, at its option, may redeem the Series B Preferred Stock for a cash redemption price of $2,500 per share, plus all accrued and unpaid dividends. The Series B Preferred Stock is not redeemable by the holders, has no maturity date and is not convertible into any other security of the Company or its affiliates.
Transactions During 2019
Dispositions/Impairments
For information explaining why BXP and BPLP may report different gains on sales of real estate or impairment losses, see the Explanatory Note that follows the cover page of this Annual Report on Form 10-K.
On January 24, 2019, we completed the sale of our 2600 Tower Oaks Boulevard property located in Rockville, Maryland for a gross sale price of approximately $22.7 million. Net cash proceeds totaled approximately $21.4 million, resulting in a loss on sale of real estate totaling approximately $0.6 million. We recognized an impairment loss totaling approximately $3.1 million for BXP and approximately $1.5 million for BPLP during the year ended December 31, 2018. 2600 Tower Oaks Boulevard is an approximately 179,000 net rentable square foot Class A office property.
At March 31, 2019, we evaluated the expected hold period of our One Tower Center property located in East Brunswick, New Jersey and, based on a shorter-than-expected hold period, we reduced the carrying value of the property to its estimated fair value at March 31, 2019 and recognized an impairment loss totaling approximately $24.0 million for BXP and approximately $22.3 million for BPLP. Our estimated fair value was based on a pending offer from a third party to acquire the property and the subsequent execution of a purchase and sale agreement on April 18, 2019 for a gross sale price of $38.0 million. On June 3, 2019, we completed the sale of the property. Net cash proceeds totaled approximately $36.6 million, resulting in a loss on sale of real estate totaling approximately $0.8 million. One Tower Center is an approximately 410,000 net rentable square foot Class A office property.
On June 28, 2019, we completed the sale of our 164 Lexington Road property located in Billerica, Massachusetts for a gross sale price of $4.0 million. Net cash proceeds totaled approximately $3.8 million, resulting in a gain on sale of real estate totaling approximately $2.5 million for BXP and approximately $2.6 million for BPLP. 164 Lexington Road is an approximately 64,000 net rentable square foot Class A office property.
On September 20, 2019, we entered into a joint venture with Canada Pension Plan Investment Board (“CPPIB”) to develop Platform 16 located in San Jose, California. Platform 16 consists of a 65-year ground lease for land totaling approximately 5.6 acres that will support the development of approximately 1.1 million square feet of commercial office space. During 2018, we entered into the ground lease, which provides for the right to purchase all of the land during a 12-month period commencing February 1, 2020 at a purchase price of approximately $134.8 million. We contributed the ground lease interest and improvements totaling approximately $28.2 million for our initial 55% interest in the joint venture. CPPIB contributed cash totaling approximately $23.1

2


million for its initial 45% interest in the joint venture. Upon the CPPIB contribution, we ceased accounting for the joint venture entity on a consolidated basis and are accounting for the joint venture entity on an unconsolidated basis using the equity method of accounting, as we have reduced our ownership interest and no longer have a controlling financial or operating interest in the joint venture entity. We did not recognize a gain on the retained or sold interest in the real estate contributed to the joint venture, as the fair value of the real estate approximated its carrying value (See “Ground Leases” and “Investments in Unconsolidated Joint Ventures” below as well as Note 19 to the Consolidated Financial Statements).
On December 20, 2019, we completed the sale of the remaining parcel of land at our Washingtonian North property located in Gaithersburg, Maryland for a gross sale price of approximately $7.8 million. Net cash proceeds totaled approximately $7.3 million, resulting in a loss on sale of real estate totaling approximately $0.1 million. We recognized an impairment loss totaling approximately $1.8 million during the year ended December 31, 2016.
Developments/Redevelopments
As of December 31, 2019, we had 11 properties under construction/redevelopment comprised of nine office properties and two residential properties, which we expect will total approximately 5.5 million net rentable square feet. We estimate the total investment to complete these projects, in the aggregate, is approximately $3.1 billion, of which approximately $1.4 billion remains to be invested as of December 31, 2019. Approximately 76% of the commercial space in these development projects was pre-leased as of February 21, 2020. For a detailed list of the properties under construction/redevelopment see “Liquidity and Capital Resources” within “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
On May 9, 2019, we entered into a 15-year lease with Google, LLC for approximately 379,000 net rentable square feet of Class A office space in a build-to-suit development project located at our 325 Main Street property at Kendall Center in Cambridge, Massachusetts. 325 Main Street consisted of an approximately 115,000 net rentable square foot Class A office property that was demolished and is being developed into an approximately 420,000 net rentable square foot Class A office property, including approximately 41,000 net rentable square feet of retail space. On May 9, 2019, we commenced development of the project. BXP and BPLP recognized approximately $9.9 million and $9.5 million, respectively, of depreciation expense associated with the acceleration of depreciation on the assets being removed from service and demolished as part of the redevelopment of the property.
On June 1, 2019, we partially placed in-service 20 CityPoint, a Class A office project with approximately 211,000 net rentable square feet located in Waltham, Massachusetts.
On September 30, 2019, we commenced the redevelopment of 200 West Street, a Class A office project with approximately 261,000 net rentable square feet located in Waltham, Massachusetts. The redevelopment is a conversion of a 126,000 square foot portion of the property to laboratory space.
On October 24, 2019, we completed and placed in-service 145 Broadway, a build-to-suit Class A office project with approximately 483,000 net rentable square feet located in Cambridge, Massachusetts.
Ground Leases
On January 24, 2019, the ground lessor under our 65-year ground lease for land totaling approximately 5.6 acres at Platform 16 located in San Jose, California made available for lease to us the remaining land parcels. As a result, we recognized the remaining portion of the right of use finance lease asset and finance lease liability. We entered into the ground lease in 2018, however, at the inception of the ground lease only a portion of the land was available for lease from the lessor, resulting in us recognizing only a portion of the ground lease. In the aggregate, the land will support the development of approximately 1.1 million square feet of commercial office space. The ground lease provides us with the right to purchase all of the land during a 12-month period commencing February 1, 2020 at a purchase price of approximately $134.8 million. We were reasonably certain we would exercise the option to purchase the land and as a result, we have concluded that the lease should be accounted for as a finance lease. As a result, we recorded an approximately $122.6 million right of use asset - finance lease and a lease liability - finance lease on our Consolidated Balance Sheets reflecting the remaining land parcels made available for lease to us (See “Dispositions/Impairments” above and “Investments in Unconsolidated Joint Ventures” below, as well as Note 19 to the Consolidated Financial Statements).

3


On July 16, 2019, we executed a 75-year ground lease with The George Washington University for land parcels at 2100 Pennsylvania Avenue located in Washington, DC and commenced development of an approximately 470,000 net rentable square foot Class A office property pursuant to a development agreement that we entered into with The George Washington University in 2016. The development agreement provided for the execution of the ground lease upon completion of the entitlement process and relocation of existing tenants. Also in 2016, we made a deposit of $15.0 million that, upon execution of the ground lease, is credited against ground rent payable under the ground lease. The present value of the lease payments exceeds substantially all of the fair value of the underlying asset and as a result, we have concluded that the ground lease should be accounted for as a finance lease. As a result, we recorded an approximately $185.1 million right of use asset - finance lease and an approximately $165.0 million lease liability - finance lease on our Consolidated Balance Sheets.
Acquisitions
On January 10, 2019, we acquired land parcels at our Carnegie Center property located in Princeton, New Jersey for a gross purchase price of approximately $51.5 million, which includes an aggregate of approximately $8.6 million of additional amounts that are payable in the future to the seller upon the development or sale of each of the parcels. The land parcels could support approximately 1.7 million square feet of development.
On August 27, 2019, we acquired 880 and 890 Winter Street located in Waltham, Massachusetts for a gross purchase price of approximately $106.0 million in cash. 880 and 890 Winter Street consists of two Class A office properties aggregating approximately 392,000 net rentable square feet.
Mortgage Notes Payable
On December 19, 2019, we used available cash to repay the bond financing collateralized by our New Dominion Technology Park, Building One property totaling approximately $26.5 million. The bond financing bore interest at a weighted-average fixed rate of approximately 7.69% per annum and was scheduled to mature on January 15, 2021. We recognized a loss from early extinguishment of debt totaling approximately $1.5 million, which amount included the payment of a prepayment penalty totaling approximately $1.4 million. New Dominion Technology Park, Building One is an approximately 235,000 net rentable square foot Class A office property located in Herndon, Virginia (See Note 19 to the Consolidated Financial Statements).
Unsecured Debt Transactions
On June 21, 2019, BPLP completed a public offering of $850.0 million in aggregate principal amount of its 3.400% unsecured senior notes due 2029. The notes were priced at 99.815% of the principal amount to yield an effective rate (including financing fees) of approximately 3.505% per annum to maturity. The notes will mature on June 21, 2029, unless earlier redeemed. The aggregate net proceeds from the offering were approximately $841.4 million after deducting underwriting discounts and transaction expenses.
On September 3, 2019, BPLP completed a public offering of $700.0 million in aggregate principal amount of its 2.900% unsecured senior notes due 2030. The notes were priced at 99.954% of the principal amount to yield an effective rate (including financing fees) of approximately 2.984% per annum to maturity. The notes will mature on March 15, 2030, unless earlier redeemed. The aggregate net proceeds from the offering were approximately $693.8 million after deducting underwriting discounts and transaction expenses.
On September 18, 2019, BPLP completed the redemption of $700.0 million in aggregate principal amount of its 5.625% senior notes due November 15, 2020. The redemption price was approximately $740.7 million. The redemption price included approximately $13.5 million of accrued and unpaid interest to, but not including, the redemption date. Excluding the accrued and unpaid interest, the redemption price was approximately 103.90% of the principal amount being redeemed. We recognized a loss from early extinguishment of debt totaling approximately $28.0 million, which amount included the payment of the redemption premium totaling approximately $27.3 million.
Equity Transactions
During the year ended December 31, 2019, BXP acquired an aggregate of 144,481 common units of limited partnership interest, including 92,678 common units issued upon the conversion of LTIP Units, 2012 OPP Units, 2013 MYLTIP Units, 2014 MYLTIP Units and 2016 MYLTIP Units presented by the holders for redemption, in exchange for an equal number of shares of BXP common stock.

Investments in Unconsolidated Joint Ventures
On January 24, 2019, a joint venture in which we have a 50% interest extended the loan collateralized by its Annapolis Junction Building Six property. At the time of the extension, the outstanding balance of the loan totaled approximately $13.0 million and was scheduled to mature on November 17, 2019, with a one-year extension option, subject to certain conditions. The extended loan has a total commitment amount of approximately $14.3 million, bears interest at a variable rate equal to LIBOR plus 2.00% per annum and matures on November 17, 2020. Annapolis Junction Building Six is a Class A office property with approximately 119,000 net rentable square feet located in Annapolis, Maryland.
On April 26, 2019, a joint venture in which we have a 50% interest obtained construction financing with a total commitment of $255.0 million collateralized by its 7750 Wisconsin Avenue development project located in Bethesda, Maryland. The construction financing bears interest at a variable rate equal to LIBOR plus 1.25% per annum and matures on April 26, 2023, with two, one-year extension options, subject to certain conditions. As of December 31, 2019, approximately $64.5 million has been drawn under the loan. 7750 Wisconsin Avenue is a 734,000 net rentable square foot build-to-suit Class A office project and below-grade parking garage.
On May 28, 2019, joint ventures in which we have a 50% interest and that own The Hub on Causeway - Podium and 100 Causeway Street development projects entered into an infrastructure development assistance agreement (the “IDAA”) with the Commonwealth of Massachusetts and the City of Boston. Per the IDAA, The Hub on Causeway - Podium development project would be reimbursed for certain costs of public infrastructure improvements using the proceeds of up to $30.0 million in aggregate principal amount of municipal bonds issued by the Commonwealth of Massachusetts. On September 16, 2019, the joint venture received the full reimbursement of costs for the public infrastructure improvements totaling approximately $28.8 million, which has been reflected as a reduction to the carrying value of the real estate of The Hub on Causeway - Podium property. The construction loan agreement for The Hub on Causeway - Podium was modified to require the joint venture to pay down the construction loan principal balance using the proceeds received from the reimbursement of costs of the public infrastructure improvements and on September 16, 2019, the joint venture that owns The Hub on Causeway - Podium development project paid down the construction loan principal balance in the amount of approximately $28.8 million. On November 22, 2019, the joint venture that owns The Hub on Causeway - Podium development project completed and fully placed in-service The Hub on Causeway - Podium development project, an approximately 382,000 net rentable square foot project containing retail and office space located in Boston, Massachusetts.
On June 27, 2019, a joint venture in which we have a 60% interest completed the sale of 540 Madison Avenue in New York City for a gross sale price of approximately $310.3 million, including the assumption by the buyer of the mortgage loan collateralized by the property totaling $120.0 million. The mortgage loan bore interest at a variable rate equal to LIBOR plus 1.10% per annum and was scheduled to mature on June 5, 2023. Net cash proceeds totaled approximately $178.7 million, of which our share was approximately $107.1 million, after the payment of transaction costs. During 2008, we recognized an other-than-temporary impairment loss on our investment in the unconsolidated joint venture. As a result, we recognized a gain on sale of real estate totaling approximately $47.2 million, which is included in Income from Unconsolidated Joint Ventures in the accompanying Consolidated Statements of Operations. 540 Madison Avenue is an approximately 284,000 net rentable square foot Class A office property.
On September 5, 2019, a joint venture in which we have a 50% interest obtained construction financing with a total commitment of $400.0 million collateralized by its 100 Causeway Street development project located in Boston, Massachusetts. The construction financing bears interest at a variable rate equal to LIBOR plus 1.50% per annum (LIBOR plus 1.375% per annum upon stabilization, as defined in the loan agreement) and matures on September 5, 2023, with two, one-year extension options, subject to certain conditions. As of December 31, 2019, approximately $81.1 million has been drawn under the loan. 100 Causeway Street is an approximately 632,000 net rentable square foot Class A office project.
On September 20, 2019, we entered into a joint venture with CPPIB to develop Platform 16 located in San Jose, California. Platform 16 consists of a 65-year ground lease for land totaling approximately 5.6 acres that will support the development of approximately 1.1 million square feet of commercial office space. We contributed the ground lease interest and improvements totaling approximately $28.2 million for our initial 55% interest in the joint

5


venture. CPPIB contributed cash totaling approximately $23.1 million for its initial 45% interest in the joint venture. We will provide customary development, property management and leasing services to the joint venture (See “Dispositions/Impairments” and “Ground Leases” above as well as Note 19 to the Consolidated Financial Statements).
On October 1, 2019, a joint venture in which we have a 50% interest partially placed in-service Dock 72, a Class A office project with approximately 670,000 net rentable square feet located in Brooklyn, New York.
On October 1, 2019, a joint venture in which we have a 50% interest partially placed in-service Hub50House, an approximately 320,000 square foot project comprised of 440 residential units located in Boston, Massachusetts.
On December 6, 2019, a joint venture in which we have a 50% interest extended the mortgage loan collateralized by Annapolis Junction Building Seven and Building Eight. At the time of the extension, the outstanding balance of the loan totaled approximately $34.8 million, bore interest at a variable rate equal to LIBOR plus 2.35% per annum and was scheduled to mature on December 7, 2019, with three, one-year extension options, subject to certain conditions. The extended loan matures on March 6, 2020. Annapolis Junction Building Seven and Building Eight are Class A office properties with approximately 127,000 and 126,000 net rentable square feet, respectively, located in Annapolis, Maryland.
Noncontrolling Interest
On April 1, 2019, we completed the acquisition of our partner’s 5% ownership interest and promoted profits interest in the consolidated entity that owns Salesforce Tower for cash totaling approximately $210.9 million, which amount was reduced by approximately $24.1 million to $186.8 million to reflect the repayment of our preferred equity and preferred return in the venture (See Note 10 to the Consolidated Financial Statements). Salesforce Tower is located in San Francisco, California. We now own 100% of Salesforce Tower. We have accounted for the transaction as an equity transaction for financial reporting purposes and have reflected the difference between the fair value of the total consideration paid and the related carrying value of the noncontrolling interest - property partnership totaling approximately $162.5 million as a decrease to Additional Paid-in Capital and Partners’ Capital in the Consolidated Balance Sheets of BXP and BPLP, respectively.
Stock Option and Incentive Plan
On February 5, 2019, BXP’s Compensation Committee approved a new equity-based, multi-year, long-term incentive program (the “2019 MYLTIP”) as a performance-based component of our overall compensation program. Under the Financial Accounting Standards Board’s Accounting Standards Codification (“ASC”) 718 “Compensation - Stock Compensation,” the 2019 MYLTIP has an aggregate value of approximately $13.5 million, which amount will generally be amortized into earnings over the four-year plan period under the graded vesting method (See Note 16 to the Consolidated Financial Statements).
On February 9, 2019, the measurement period for our 2016 MYLTIP awards ended and, based on BXP’s relative TSR performance, the final awards were determined to be 69.5% of target or an aggregate of approximately $13.6 million (after giving effect to employee separations). As a result, an aggregate of 364,980 2016 MYLTIP Units that had been previously granted were automatically forfeited.
Business and Growth Strategies
Business Strategies
Our primary business objective is to maximize return on investment to provide our investors with the greatest possible total return in all points of the economic cycle. Our strategies to achieve this objective are:
to target a few carefully selected geographic markets—Boston, Los Angeles, New York, San Francisco and Washington, DC—and to be one of the leading, if not the leading, developers, owners and managers in each of those markets with a full-service office in each market providing property management, leasing, development, construction and legal expertise. We select markets and submarkets with a diverse economic base and a deep pool of prospective tenants in various industries and where tenants have demonstrated a preference for high-quality office buildings and other facilities. Additionally, our markets have historically been able to recruit new talent to them and as such created job growth that results in growth in rental rates and occupancy over time. We have explored, and may continue to explore for future investment, select domestic and international markets that exhibit these same traits;

6


to emphasize markets and submarkets within those markets where the difficulty of receiving the necessary approvals for development and the necessary financing constitute high barriers to the creation of new supply, and where skill, financial strength and diligence are required to successfully develop, finance and manage high-quality office, research and development space, as well as selected retail and residential space;
to take on complex, technically challenging development projects, leveraging the skills of our management team to successfully develop, acquire or reposition properties that other organizations may not have the capacity or resources to pursue;
to own and develop high-quality real estate designed to meet the demands of today’s tenants who require sophisticated telecommunications and related infrastructure, support services, sustainable features and amenities, and to manage those facilities so as to become the landlord of choice for both existing and prospective clients;
to opportunistically acquire assets that increase our market share in the markets in which we have chosen to concentrate, as well as potential new markets, which exhibit an opportunity to improve returns through repositioning (through a combination of capital improvements and shift in marketing strategy), changes in management focus and leasing;
to explore joint venture opportunities with existing property owners located in desirable locations, who seek to benefit from the depth of development and management expertise we are able to provide and our access to capital, and/or to explore joint venture opportunities with strategic institutional partners, leveraging our skills as developers, owners and managers of Class A office space and mixed-use complexes;
to pursue on a selective basis the sale of properties or interests therein, including core properties, to either (1) take advantage of the demand for our premier properties and realize the value we have created or (2) pare from our portfolio properties that we believe have slower future growth potential;
to seek third-party development contracts to enable us to retain and utilize our existing development and construction management staff, especially when our internal development is less active or when new development is less-warranted due to market conditions; and
to enhance our capital structure through our access to a variety of sources of capital and proactively manage our debt expirations. In the current economic climate with relatively low interest rates we have and will continue to attempt to lower the cost of our debt capital and seek opportunities to lock in such low rates through early debt repayment, refinancings and interest rate hedges.
Growth Strategies
External Growth Strategies
We believe that our development experience, our organizational depth and our balance sheet position us to continue to selectively develop a range of property types, including high-rise urban developments, mixed-use developments (including office, residential and retail), low-rise suburban office properties and research and laboratory space, within budget and on schedule. We believe we are also well positioned to achieve external growth through acquisitions. Other factors that contribute to our competitive position include:
our control of sites (including sites under contract or option to acquire) in our markets that could support approximately 15.5 million additional square feet of new office, retail and residential development;
our reputation gained through 50 years of successful operations and the stability and strength of our existing portfolio of properties;
our relationships with leading national corporations, universities and public institutions, including government agencies, seeking new facilities and development services;
our relationships with nationally recognized financial institutions that provide capital to the real estate industry;
our track record and reputation for executing acquisitions efficiently provide comfort to domestic and foreign institutions, private investors and corporations who seek to sell commercial real estate in our market areas;

7


our ability to act quickly on due diligence and financing;
our relationships with institutional buyers and sellers of high-quality real estate assets;
our ability to procure entitlements from multiple municipalities to develop sites and attract land owners to sell or partner with us; and
our relationship with domestic and foreign investors who seek to partner with companies like ours.
Opportunities to execute our external growth strategy fall into three categories:
Development in selected submarkets. We believe the selected development of well-positioned office buildings, residential buildings and mixed-use complexes may be justified in our markets. We believe in acquiring land after taking into consideration timing factors relating to economic cycles and in response to market conditions that allow for its development at the appropriate time. While we purposely concentrate in markets with high barriers-to-entry, we have demonstrated throughout our 50-year history, an ability to make carefully timed land acquisitions in submarkets where we can become one of the market leaders in establishing rent and other business terms. We believe that there are opportunities at key locations in our existing and other markets for a well-capitalized developer to acquire land with development potential.
In the past, we have been particularly successful at acquiring sites or options to purchase sites that need governmental approvals for development. Because of our development expertise, knowledge of the governmental approval process and reputation for quality development with local government regulatory bodies, we generally have been able to secure the permits necessary to allow development and to profit from the resulting increase in land value. We seek complex projects where we can add value through the efforts of our experienced and skilled management team leading to attractive returns on investment.
Our strong regional relationships and recognized development expertise have enabled us to capitalize on unique build-to-suit opportunities. We intend to seek and expect to continue to be presented with such opportunities in the near term allowing us to earn relatively significant returns on these development opportunities through multiple business cycles.
Acquisition of assets and portfolios of assets from institutions or individuals. We believe that due to our size, management strength and reputation, we are well positioned to acquire portfolios of assets or individual properties from institutions or individuals if valuations meet our criteria. In addition, we believe that our market knowledge and our liquidity and access to capital may provide us with a competitive advantage when pursuing acquisitions. Opportunities to acquire properties may also come through the purchase of first mortgage or mezzanine debt. We are also able to appeal to sellers wishing to contribute on a tax-deferred basis their ownership of property for equity in a diversified real estate operating company that offers liquidity through access to the public equity markets in addition to a quarterly distribution. Our ability to offer common and preferred units of limited partnership in BPLP to sellers who would otherwise recognize a taxable gain upon a sale of assets for cash or BXP’s common stock may facilitate this type of transaction on a tax-efficient basis. Recent Treasury regulations may limit certain of the tax benefits previously available to sellers in these transactions.
Acquisition of underperforming assets and portfolios of assets. We believe that because of our in-depth market knowledge and development experience in each of our markets, our national reputation with brokers, financial institutions, owners of real estate and others involved in the real estate market and our access to competitively-priced capital, we are well-positioned to identify and acquire existing, underperforming properties for competitive prices and to add significant additional value to such properties through our effective marketing strategies, repositioning/redevelopment expertise and a responsive property management program.

Internal Growth Strategies
We believe that opportunities will exist to increase cash flow from our existing properties through an increase in occupancy and rental rates because they are of high quality and in desirable locations. Additionally, our markets have diversified economies that have historically experienced job growth and increased use of office space, resulting in growth in rental rates and occupancy over time. Our strategy for maximizing the benefits from these opportunities is three-fold: (1) to provide high-quality property management services using our employees in order to encourage tenants to renew, expand and relocate in our properties, (2) to achieve speed and transaction cost efficiency in replacing departing tenants through the use of in-house services for marketing, lease negotiation and construction of tenant and capital improvements and (3) to work with new or existing tenants with space expansion or contraction needs, leveraging our expertise and clustering of assets to maximize the cash flow from our assets. We expect to continue our internal growth as a result of our ability to:
Cultivate existing submarkets and long-term relationships with credit tenants. In choosing locations for our properties, we have paid particular attention to transportation and commuting patterns, physical environment, adjacency to established business centers and amenities, proximity to sources of business growth and other local factors.
The weighted-average lease term of our in-place leases, including leases signed by our unconsolidated joint ventures, was approximately 8.4 years at December 31, 2019, and we continue to cultivate long-term leasing relationships with a diverse base of high-quality, financially stable tenants. Based on leases in place at December 31, 2019, leases with respect to approximately 7.0% of the total square feet in our portfolio, including unconsolidated joint ventures, will expire in calendar year 2020. 
Directly manage our office properties to maximize the potential for tenant retention. We provide property management services ourselves, rather than contracting for this service, to maintain awareness of and responsiveness to tenant needs. We and our properties also benefit from cost efficiencies produced by an experienced work force attentive to preventive maintenance and energy management and from our continuing programs to assure that our property management personnel at all levels remain aware of their important role in tenant relations. In addition, we reinvest in our properties by adding new services and amenities that are desirable to our tenants.
Replace tenants quickly at best available market terms and lowest possible transaction costs. We believe that we are well-positioned to attract new tenants and achieve relatively high rental and occupancy rates as a result of our well-located, well-designed and well-maintained properties, our reputation for high-quality building services and responsiveness to tenants, and our ability to offer expansion and relocation alternatives within our submarkets.
Extend terms of existing leases to existing tenants prior to expiration. We have also successfully structured early tenant renewals, which have reduced the cost associated with lease downtime while securing the tenancy of our highest quality credit-worthy tenants on a long-term basis and enhancing relationships.
Re-development of existing assets. We believe the select re-development of assets within our portfolio, where through the ability to increase the building size and/or to increase cash flow and generate appropriate returns on incremental investment after consideration of the asset’s current and future cash flows, may be desirable. This generally occurs in situations in which we are able to increase the building’s size, improve building systems and sustainability features, and/or add tenant amenities, thereby increasing tenant demand, generating acceptable returns on incremental investment and enhancing the long-term value of the property and the company. In the past, we have been particularly successful at gaining local government approval for increased density at several of our assets, providing the opportunity to enhance value at a particular location. Our strong regional relationships and recognized re-development expertise have enabled us to capitalize on unique build-to-suit opportunities. We intend to seek and expect to continue to be presented with such opportunities in the near term allowing us to earn attractive returns on these development opportunities through multiple business cycles.
Policies with Respect to Certain Activities
The discussion below sets forth certain additional information regarding our investment, financing and other policies. These policies have been determined by BXP’s Board of Directors and, in general, may be amended or revised from time to time by the Board of Directors.

Investment Policies
Investments in Real Estate or Interests in Real Estate
Our investment objectives are to provide quarterly cash dividends/distributions to our securityholders and to achieve long-term capital appreciation through increases in our value. We have not established a specific policy regarding the relative priority of these investment objectives.
We expect to continue to pursue our investment objectives primarily through the ownership of our current properties, development projects and other acquired properties. We currently intend to continue to invest primarily in developments of properties and acquisitions of existing improved properties or properties in need of redevelopment, and acquisitions of land that we believe have development potential, primarily in our existing markets of Boston, Los Angeles, New York, San Francisco and Washington, DC. We have explored and may continue to explore for future investment select domestic and international markets that exhibit these same traits. Future investment or development activities will not be limited to a specified percentage of our assets. We intend to engage in such future investment or development activities in a manner that is consistent with the maintenance of BXP’s status as a REIT for federal income tax purposes. In addition, we may purchase or lease income-producing commercial and other types of properties for long-term investment, expand and improve the real estate presently owned or other properties purchased, or sell such real estate properties, in whole or in part, when circumstances warrant. We do not have a policy that restricts the amount or percentage of assets that will be invested in any specific property, however, our investments may be restricted by our debt covenants.
We may also continue to participate with third parties in property ownership, through joint ventures or other types of co-ownership. These investments may permit us to own interests in larger assets without unduly restricting diversification and, therefore, add flexibility in structuring our portfolio.
Equity investments may be subject to existing mortgage financing and other indebtedness or such financing or indebtedness as may be incurred in connection with acquiring or refinancing these investments. Debt service on such financing or indebtedness will have a priority over any distributions with respect to BXP’s common stock. Investments are also subject to our policy not to be treated as an investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). 
Investments in Real Estate Mortgages
While our current portfolio consists primarily of, and our business objectives emphasize, equity investments in commercial real estate, we may, at the discretion of the Board of Directors of BXP, invest in mortgages and other types of real estate interests consistent with BXP’s qualification as a REIT. Investments in real estate mortgages run the risk that one or more borrowers may default under such mortgages and that the collateral securing such mortgages may not be sufficient to enable us to recoup our full investment. We may invest in participating, convertible or traditional mortgages if we conclude that we may benefit from the cash flow, or any appreciation in value of the property or as an entrance to the fee ownership. As of December 31, 2019, we had two note receivables outstanding, which aggregated approximately $95.9 million.
Securities of or Interests in Entities Primarily Engaged in Real Estate Activities
Subject to the percentage of ownership limitations and gross income and asset tests necessary for BXP’s REIT qualification, we also may invest in securities of other REITs, other entities engaged in real estate activities or securities of other issuers, including for the purpose of exercising control over such entities.
Dispositions
Our decision to dispose or partially dispose of properties is based upon the periodic review of our portfolio and the determination by the Board of Directors of BXP that such action would be in our best interests. Any decision to dispose of a property will be authorized by the Board of Directors of BXP or a committee thereof. Some holders of limited partnership interests in BPLP could incur adverse tax consequences upon the sale of certain of our properties that differ from the tax consequences to BXP. Consequently, holders of limited partnership interests in BPLP may have different objectives regarding the appropriate pricing and timing of any such sale. Such different tax treatment derives in most cases from the fact that we acquired these properties in exchange for partnership interests in contribution transactions structured to allow the prior owners to defer taxable gain. Generally, this deferral continues so long as we do not dispose of the properties in a taxable transaction. Unless a sale by us of these properties is structured as a like-kind exchange under Section 1031 of the Internal Revenue of 1986, as amended (the “Code”) or in a manner that otherwise allows deferral to continue, recognition of the deferred tax gain

10


allocable to these prior owners is generally triggered by a sale. As of December 31, 2019, we have no properties that are subject to a tax protection agreement.
Financing Policies 
The agreement of limited partnership of BPLP and BXP’s certificate of incorporation and bylaws do not limit the amount or percentage of indebtedness that we may incur. Further, we do not have a policy limiting the amount of indebtedness that we may incur, nor have we established any limit on the number or amount of mortgages that may be placed on any single property or on our portfolio as a whole. However, our mortgages, credit facilities, joint venture agreements and unsecured debt securities contain customary restrictions, requirements and other limitations on our ability to incur indebtedness. In addition, we evaluate the impact of incremental leverage on our debt metrics and the credit ratings of BPLP’s publicly traded debt. A reduction in BPLP’s credit ratings could result in us borrowing money at higher interest rates.
The Board of Directors of BXP will consider a number of factors when evaluating our level of indebtedness and when making decisions regarding the incurrence of indebtedness, including the purchase price of properties to be acquired with debt financing, the estimated market value of our properties upon refinancing, the entering into agreements such as interest rate swaps, caps, floors and other interest rate hedging contracts and the ability of particular properties and us as a whole to generate cash flow to cover expected debt service. 
Policies with Respect to Other Activities
As the sole general partner of BPLP, BXP has the authority to issue additional common and preferred units of limited partnership interest of BPLP. BXP has issued, and may in the future issue, common or preferred units of limited partnership interest to persons who contribute their direct or indirect interests in properties to us in exchange for such common or preferred units. We have not engaged in trading, underwriting or agency distribution or sale of securities of issuers other than BXP and BPLP does not intend to do so. At all times, we intend to make investments in such a manner as to enable BXP to maintain its qualification as a REIT, unless, due to changes in circumstances or to the tax code, the Board of Directors of BXP determines that it is no longer in the best interest of BXP to qualify as a REIT. We may make loans to third parties, including, without limitation, to joint ventures in which we participate or in connection with the disposition of a property. We intend to make investments in such a way that we will not be treated as an investment company under the 1940 Act. Our policies with respect to these and other activities may be reviewed and modified or amended from time to time by the Board of Directors of BXP. 
Sustainability
Our Sustainability Strategy
As the largest publicly-traded office REIT (based on total market capitalization) as of December 31, 2019 in the United States that develops, owns and manages primarily Class A office properties, we actively work to promote our growth and operations in a sustainable and responsible manner across our five regions. The BXP sustainability strategy is to conduct our business, the development and operation of new and existing buildings, in a manner that contributes to positive economic, social and environmental outcomes for our customers, shareholders, employees and the communities we serve. Our investment philosophy is shaped by our core strategy of long-term ownership and our commitment to our communities and the centers of commerce and civic life that make them thrive. We are focused on developing and maintaining healthy, high-performance buildings, while simultaneously mitigating operational costs and the potential external impacts of energy, water, waste, greenhouse gas emissions and climate change. To that end, we have publicly adopted long-term energy, emissions, water and waste goals that establish aggressive reduction targets and have been aligned with the United Nations Sustainable Development Goals. BXP is a corporate member of the U.S. Green Building Council® (“USGBC”) and has a long history of owning, developing and operating properties that are certified under USGBC’s Leadership in Energy and Environmental Design™ (LEED®) rating system. In addition, we have been an active participant in the green bond market since 2018, which provides access to sustainability-focused investors interested in the positive environmental externalities of our business activities. BXP and its employees also make a social impact through charitable giving, volunteerism, public realm investments and diversity and inclusion. Through these efforts, we demonstrate that operating and developing commercial real estate can be conducted with a conscious regard for the environment and wider society while mutually benefiting our stakeholders.

11


Industry Leadership in Sustainability
We have been recognized as an industry leader in sustainability. In 2019, BXP ranked among the top 4% of all real estate companies in the Global Real Estate Sustainability Benchmark (“GRESB”) assessment. 2019 was the eighth consecutive year that BXP has ranked in the top quartile of GRESB assessment participants, earning another “Green Star” recognition and the highest GRESB 5-star Rating. We have widely adopted green building practices and have LEED certified over 26 million square feet of our portfolio, of which 93% is certified at the highest Gold and Platinum levels. In 2014, 2015, 2017, 2018 and 2019, BXP was selected by the National Association of Real Estate Investment Trusts (“Nareit”) as a Leader in the Light Award winner. In 2019, BXP earned the “Most Innovative” Leader in the Light Award. This award is given to only one company and is the highest achievement in sustainability innovation for all REITs and real estate companies.
BXP was also named one of America’s Most Responsible Companies by Newsweek magazine in 2019. BXP ranked 122nd on Newsweek’s 2020 list of America’s 300 Most Responsible Companies, the second highest ranking given to a public REIT and the highest ranking of any office company. We recognize and have taken steps to address the role of our tenants in supporting the execution of our sustainability strategy through our leasing activity. BXP has been named a Green Lease Leader by the Institute for Market Transformation and the U.S. Department of Energy for exhibiting a strong commitment to high performance and sustainability in buildings and best practices in leasing. BXP’s master lease form includes green lease clauses that support a more sustainable tenant-landlord relationship.
Sustainability Accounting Standards Board (“SASB”)
The Real Estate Sustainability Accounting Standard issued by SASB in 2018 proposes sustainability accounting metrics designed for disclosure in mandatory filings, such as the Annual Report on Form 10-K, and serves as the framework against which we have aligned our disclosures for sustainability information. The recommended energy and water management activity metrics for the real estate industry include energy consumption data coverage as a percentage of floor area (“Energy Intensity”); percentage of eligible portfolio that is certified ENERGY STAR® (“ENERGY STAR certified”); total energy consumed by portfolio area (“Total Energy Consumption”); water withdrawal as a percentage of total floor area (“Water Intensity”); and total water withdrawn by portfolio area (“Total Water Consumption”). Energy and water data is collected from utility bills and submeters and is assured by a third-party, including all SASB 2018 energy and water metrics, which have been assured. During the 2018 calendar year, 68 buildings representing 71% of our eligible portfolio were ENERGY STAR certified. A licensed professional has verified all ENERGY STAR applications.
The charts below detail our Energy Intensity, Total Energy Consumption, Water Intensity and Total Water Consumption for 2015 through 2018 for which data on occupied and actively-managed properties was available.1,2,3,4,5

The charts reflect the performance of our occupied and actively-managed office building portfolio in Boston, Los Angeles, New York, San Francisco and Washington, DC. Occupied office buildings are buildings with no more than 50% vacancy. Actively-managed buildings are buildings where we have operational control of building system performance and investment decisions. At the end of the 2018 calendar year, this included 97 buildings totaling 39.2 million gross square feet.

The scope of energy includes energy purchased from sources external to us and our tenants or produced by us or our tenants and energy from all sources, including fuel, gas, electricity and steam. Energy use intensity (kBtu/SF) has been weather normalized.
(5)
Water sources include surface water (including water from wetlands, rivers, lakes and oceans), groundwater, rainwater collected directly and stored by the registrant, wastewater obtained from other entities, municipal water supplies or supply from other water utilities.
Climate Resilience
We are focused on climate preparedness and resiliency in advancement of our sustainability strategy. As a long-term owner and active manager of real estate assets in operation and under development, we strive to obtain adaptive capacity by continuing to proactively implement measures and planning and decision-making processes to protect our investments by improving resilience. We are preparing for long-term climate risk by considering climate change scenarios and will continue to assess climate change vulnerabilities resulting from potential future climate scenarios and sea level rise. Event-driven (acute) and longer-term (chronic) physical risks that may result from climate change could have a material adverse effect on our properties, operations and business. Management’s role in assessing and managing these climate-related risks and initiatives is spread across multiple teams across our organization, including our executive leadership and our Sustainability, Risk Management, Development, Construction and Property Management departments. Climate resilience measures include training and implementation of emergency response plans and the engagement of our executives and BXP’s Board of Directors on climate change and other environmental, social and governance (“ESG”) aspects.
Reporting
A notable part of our commitment to sustainable development and operations is our commitment to transparent reporting of ESG performance indicators, as we recognize the importance of this information to investors, lenders and others in understanding how BXP assesses sustainability information and evaluates risks and opportunities. We publish an annual sustainability report that is aligned with the Global Reporting Initiative reporting framework, United Nations Sustainable Development Goals and the SASB framework and includes our strategy, key performance indicators, annual like-for-like comparisons, achievements and historical sustainability reports, which is available on our website at http://www.bxp.com under the heading “Sustainability.” In addition, we continue to work to further align our reporting with the recommendations of the Financial Stability Board’s Task Force on Climate-related Financial Disclosures (“TCFD”) to disclose climate-related financial risks and opportunities.
In 2018 and 2019, BPLP issued an aggregate of $1.85 billion of green bonds. The terms of the green bonds have use of proceeds restrictions limiting its allocation to “eligible green projects.” We published our first Green Bond Allocation Report in June 2019 disclosing the full allocation of approximately $988 million in net proceeds from BPLP’s inaugural green bond offering to the eligible green project at our Salesforce Tower property in San Francisco, California. The Green Bond Allocation Report is available on our website at http://www.bxp.com under the heading “Sustainability.”
Except for the documents specifically incorporated by reference into this Annual Report on Form 10-K, information contained on our website or that can be accessed through our website is not incorporated by reference into this Annual Report on Form 10-K.
Environmental Matters
It is our policy to retain independent environmental consultants to conduct or update Phase I environmental assessments (which generally do not involve invasive techniques such as soil or ground water sampling) and asbestos surveys in connection with our acquisition of properties. These pre-purchase environmental assessments have not revealed environmental conditions that we believe will have a material adverse effect on our business, assets, financial condition, results of operations or liquidity, and we are not otherwise aware of environmental conditions with respect to our properties that we believe would have such a material adverse effect. However, from

13


time to time environmental conditions at our properties have required and may in the future require environmental testing and/or regulatory filings, as well as remedial action. 
In February 1999, we (through a joint venture) acquired from Exxon Corporation a property in Massachusetts that was formerly used as a petroleum bulk storage and distribution facility and was known by the state regulatory authority to contain soil and groundwater contamination. We developed an office park on the property. We engaged a specially licensed environmental consultant to oversee the management of contaminated soil and groundwater that was disturbed in the course of construction. Under the property acquisition agreement, Exxon agreed to (1) bear the liability arising from releases or discharges of oil and hazardous substances which occurred at the site prior to our ownership, (2) continue monitoring and/or remediating such releases and discharges as necessary and appropriate to comply with applicable requirements, and (3) indemnify us for certain losses arising from preexisting site conditions. Any indemnity claim may be subject to various defenses, and there can be no assurance that the amounts paid under the indemnity, if any, would be sufficient to cover the liabilities arising from any such releases and discharges. 
Environmental investigations at some of our properties and certain properties owned by our affiliates have identified groundwater contamination migrating from off-site source properties. In each case we engaged a licensed environmental consultant to perform the necessary investigations and assessments, and to prepare any required submittals to the regulatory authorities. In each case the environmental consultant concluded that the properties qualify under the regulatory program or the regulatory practice for a status which eliminates certain deadlines for conducting response actions at a site. We also believe that these properties qualify for liability relief under certain statutory provisions or regulatory practices regarding upgradient releases. Although we believe that the current or former owners of the upgradient source properties may bear responsibility for some or all of the costs of addressing the identified groundwater contamination, we will take such further response actions (if any) that we deem necessary or advisable. Other than periodic testing at some of these properties, no such additional response actions are anticipated at this time. 
Some of our properties and certain properties owned by our affiliates are located in urban, industrial and other previously developed areas where fill or current or historical use of the areas have caused site contamination. Accordingly, it is sometimes necessary to institute special soil and/or groundwater handling procedures and/or include particular building design features in connection with development, construction and other property operations in order to achieve regulatory closure and/or ensure that contaminated materials are addressed in an appropriate manner. In these situations, it is our practice to investigate the nature and extent of detected contamination, including potential issues associated with contaminant migration, assess potential liability risks and estimate the costs of required response actions and special handling procedures. We then use this information as part of our decision-making process with respect to the acquisition, deal structure and/or development of the property. For example, we own a parcel in Massachusetts which was formerly used as a quarry/asphalt batching facility. Pre-purchase testing indicated that the site contained relatively low levels of certain contaminants. We have developed an office park on this property. Prior to and during redevelopment activities, we engaged a specially licensed environmental consultant to monitor environmental conditions at the site and prepare necessary regulatory submittals based on the results of an environmental risk characterization. A submittal has been made to the regulatory authorities in order to achieve regulatory closure at this site. The submittal included an environmental deed restriction that mandates compliance with certain protective measures in a portion of the site where low levels of residual soil contamination have been left in place in accordance with applicable laws. 
We expect that resolution of the environmental matters described above will not have a material impact on our business, assets, financial condition, results of operations or liquidity. However, we cannot assure you that we have identified all environmental liabilities at our properties, that all necessary remediation actions have been or will be undertaken at our properties, that we will be indemnified, in full or at all, or that we will have insurance coverage in the event that such environmental liabilities arise.

Competition
We compete in the leasing of office, retail and residential space with a considerable number of other real estate companies, some of which may have greater marketing and financial resources than are available to us. In addition, our hotel property competes for guests with other hotels, some of which may have greater marketing and financial resources than are available to us and to the manager of our one hotel, Marriott International, Inc. 
Principal factors of competition in our primary business of owning, acquiring and developing office properties are the quality of properties, leasing terms (including rent and other charges and allowances for tenant improvements), attractiveness and convenience of location, the quality and breadth of tenant services and amenities provided, and reputation as an owner and operator of quality office properties in the relevant market. Additionally, our ability to compete depends upon, among other factors, trends in the national and local economies, investment alternatives, financial condition and operating results of current and prospective tenants, availability and cost of capital, construction and renovation costs, taxes, utilities, governmental regulations, legislation and population trends. 

15


In addition, we currently have six residential properties (including two properties under construction) and may in the future decide to acquire or develop additional residential properties. As an owner, we will also face competition for prospective residents from other operators/owners whose properties may be perceived to offer a better location or better amenities or whose rent may be perceived as a better value given the quality, location and amenities that the resident seeks. We will also compete against condominiums and single-family homes that are for sale or rent. Because the scale of our residential portfolio is relatively small, we expect to continue to retain third parties to manage our residential properties.
Our Hotel Property
We operate our hotel property through a taxable REIT subsidiary. The taxable REIT subsidiary, a wholly-owned subsidiary of BPLP, is the lessee pursuant to a lease for the hotel property. As lessor, BPLP is entitled to a percentage of gross receipts from the hotel property. The hotel lease is intended to provide the economic benefits of ownership of the underlying real estate to flow to us as rental income, while our taxable REIT subsidiary earns the profit from operating the property as a hotel. Marriott International, Inc. continues to manage the hotel property under the Marriott name and under terms of the existing management agreements. Marriott has been engaged under a separate long-term incentive management agreement to operate and manage the hotel on behalf of the taxable REIT subsidiary.
Recent Tax Legislation Affecting BXP and BPLP
The following discussion supplements and updates the disclosures under “United States Federal Income Tax Considerations” in the prospectus dated June 2, 2017 contained in our Registration Statement on Form S-3 filed with the SEC on June 2, 2017, as well as the disclosures under “United States Federal Income Tax Considerations” in the prospectus supplement dated June 2, 2017.
Qualified Group Legal Services
Section 501(c)(20) of the Internal Revenue Code of 1986, as amended (the “Code”), has been repealed. Therefore the reference to qualified group legal services plans under “United States Federal Income Tax Considerations—Taxation of Tax-Exempt Stockholders” is no longer applicable.
Backup Withholding
The rate for backup withholding has recently been reduced. It is now 24%, not 28% as stated in “United States Federal Income Tax Considerations—Taxation of Holders of Certain Fixed Rate Debt Securities—Taxation of Taxable U.S. Holders.”
Certain Foreign Income Inclusions
The Internal Revenue Service has advised that, if a REIT is a shareholder of a controlled foreign corporation or a passive foreign investment company, the income it must recognize on account of such ownership under sections 951(a)(1), 951A, 1291(a), § 1293(a)(1), or § 1296(a) will generally be treated as qualifying income for purposes of the 95% gross income test. In addition, foreign currency gain with respect to distributions of previously taxed earnings and profits will generally be excluded from income for purposes of the 95% gross income test.
Tax Cuts and Jobs Act of 2017
The Tax Cuts and Jobs Act of 2017 (the “TCJA”), generally applicable for tax years beginning after December 31, 2017, made significant changes to the Code, including a number of provisions of the Code that affect the taxation of businesses and their owners, including REITs and their stockholders. Among other changes, these include the following:

For tax years beginning before January 1, 2026, non-corporate taxpayers are permitted to take a 20% deduction for certain pass-through business income, including dividends received from REITs that are not designated as capital gain dividends or qualified dividend income, subject to certain limitations. The maximum U.S. federal income tax rate for individuals has been reduced from 39.6% to 37%.


16


The maximum U.S. federal income tax rate for corporations has been reduced from 35% to 21%, and the alternative minimum tax has been eliminated for corporations, which would generally reduce the amount of U.S. federal income tax payable by our taxable REIT subsidiaries and by us to the extent we were subject corporate U.S. federal income tax (for example, if we distributed less than 100% of our taxable income or recognized built-in gains in assets acquired from C corporations). In addition, the maximum withholding rate on distributions by us to non-U.S. stockholders that are treated as attributable to gain from the sale or exchange of a U.S. real property interest was reduced from 35% to 21%.

Certain new limitations on the deductibility of interest expense now apply, which limitations may affect the deductibility of interest paid or accrued by us or our taxable REIT subsidiaries. Alternatively, we may be able to avoid the new limitations on interest expense by irrevocably electing to treat an investment as an “electing real property trade or business.” As a consequence of making such election, we would be required to use an alternative depreciation system with generally longer recovery periods. We have made this election for our own leasing business and will determine whether to make such election for any investment held through an entity we control.

Certain new limitations on net operating losses now apply, which limitations may affect net operating losses generated by us or our taxable REIT subsidiaries.

New accounting rules generally require us to recognize certain income items for federal income tax purposes no later than when we take the item into account for financial statement purposes, which may accelerate our recognition of certain income items.
This summary does not purport to be a detailed discussion of the changes to U.S. federal income tax laws as a result of the enactment of the TCJA. Technical corrections or other amendments to the TCJA or administrative guidance interpreting the TCJA may be forthcoming at any time. We cannot predict the long-term effect of the TCJA or any future law changes on REITs or their stockholders. Investors are urged to consult their own tax advisors regarding the effect of the TCJA based on their particular circumstances.
Consolidated Appropriations Act
On March 23, 2018, President Donald J. Trump signed into law the Consolidated Appropriations Act, 2018 (the “CAA”), which amended various provisions of the Internal Revenue Code of 1986, as amended, and implicate certain tax-related disclosures contained in the prospectus. As a result, the discussion under “United States Federal Income Tax Considerations—Taxation of Stockholders and Potential Tax Consequences of Their Investment in Shares of Common Stock or Preferred Stock—Taxation of Non-U.S. Stockholders” in the second full paragraph on page 65 and in the first full paragraph on page 66 of each of the two documents listed above, respectively, is replaced with the following paragraphs:
Qualified Shareholders. For periods on or after December 18, 2015, to the extent our stock is held directly (or indirectly through one or more partnerships) by a “qualified shareholder,” it will not be treated as a USRPI. Further, to the extent such treatment applies, any distribution to such shareholder will not be treated as gain recognized from the sale or exchange of a USRPI. For these purposes, a qualified shareholder is generally a non-U.S. stockholder that (i)(A) is eligible for treaty benefits under an income tax treaty with the United States that includes an exchange of information program, and the principal class of interests of which is listed and regularly traded on one or more stock exchanges as defined by the treaty, or (B) is a foreign limited partnership organized in a jurisdiction with an exchange of information agreement with the United States and that has a class of regularly traded limited partnership units (having a value greater than 50% of the value of all partnership units) on the New York Stock Exchange or Nasdaq, (ii) is a “qualified collective investment vehicle” (within the meaning of Section 897(k)(3)(B) of the Code) and (iii) maintains records of persons holding 5% or more of the class of interests described in clauses (i)(A) or (i)(B) above. However, in the case of a qualified shareholder having one or more “applicable investors,” the exception described in the first sentence of this paragraph will not apply to the applicable percentage of the qualified shareholder’s stock (with “applicable percentage” generally meaning the percentage of the value of the interests in the qualified shareholder held by applicable investors after applying certain constructive ownership rules). The applicable percentage of the amount realized by a qualified shareholder on the disposition of our stock or with respect to a distribution from us attributable to gain from the sale or exchange of a USRPI will be treated as amounts realized from the disposition of USRPIs. Such treatment shall also apply to applicable investors in respect of distributions treated as a sale or exchange of stock with respect to a qualified shareholder. For these purposes, an “applicable investor” is a person who generally holds an interest in the qualified shareholder and holds

17


more than 10% of our stock applying certain constructive ownership rules. Subject to the exception described above for qualified shareholders having one or more applicable investors, distributions received by qualified shareholders will be taxed as described above at -Dividends as if the distribution is not attributable to the sale of a USRPI. Gain treated as gain from the sale or exchange of our stock (including capital gain dividends and distributions treated as gain from the sale or exchange of our stock under the rules described above at - Dividends) will not be subject to tax unless such gain is treated as effectively connected with the qualified shareholder’s conduct of a U.S. trade or business, in which case the qualified shareholder generally will be subject to a tax at the graduated rates applicable to ordinary income, in the same manner as U.S. stockholders.
Qualified Foreign Pension Funds. For periods on or after December 18, 2015, for FIRPTA purposes neither a “qualified foreign pension fund” nor any “qualified controlled entity” is treated as a Non-U.S. Stockholder. A “qualified foreign pension fund” is an organization or arrangement (i) created or organized in a foreign country, (ii) established by a foreign country (or one or more political subdivisions thereof) or one or more employers to provide retirement or pension benefits to current or former employees (including self-employed individuals) or their designees as a result of, or in consideration for, services rendered, (iii) which does not have a single participant or beneficiary that has a right to more than 5% of its assets or income, (iv) which is subject to government regulation and with respect to which annual information about its beneficiaries is provided, or is otherwise available, to relevant local tax authorities and (v) with respect to which, under its local laws, (A) contributions that would otherwise be subject to tax are deductible or excluded from its gross income or taxed at a reduced rate, or (B) taxation of its investment income is deferred, or such income is excluded from its gross income or taxed at a reduced rate. A “qualified controlled entity” is an entity all the interests of which are held by a qualified foreign pension fund. Alternatively, under proposed Treasury Regulations that taxpayers generally may rely on, but which are subject to change, a “qualified controlled entity” is a trust or corporation organized under the laws of a foreign country all of the interests of which are held by one or more qualified foreign pension funds either directly or indirectly through one or more qualified controlled entities or partnerships. Gain of a qualified foreign pension fund or qualified controlled entity treated as gain from the sale or exchange of our stock, distributions treated as gain from the sale or exchange of our stock under the rules described above at - Dividends, and distributions attributable to gains from sales of USRPIs will not be subject to U.S. federal income or withholding tax unless such gain is treated as effectively connected with the qualified foreign pension fund's (or the qualified controlled entity's, as applicable) conduct of a U.S. trade or business, in which case the qualified foreign pension fund (or qualified controlled entity) generally will be subject to a tax at the same graduated rates applicable to U.S. Stockholders, unless an applicable income tax treaty provides otherwise, and may be subject to the 30% branch profits tax on its effectively connected earnings and profits, subject to adjustments, in the case of a foreign corporation.
FATCA Proposed Regulations
On December 18, 2018, the Internal Revenue Service promulgated proposed regulations under Sections 1471-1474 of the Code (commonly referred to as FATCA), which proposed regulations eliminate FATCA withholding on gross proceeds and thus implicate certain tax-related disclosures contained in the prospectus and the prospectus supplement. While these regulations have not yet been finalized, taxpayers are generally entitled to rely on the proposed regulations (subject to certain limited exceptions). As a result, the discussion under “United States Federal Income Tax Considerations—Taxation of Stockholders and Potential Tax Consequences of Their Investment in Shares of Common Stock or Preferred Stock—Taxation of Non-U.S. Stockholders—Withholding on Certain Foreign Accounts and Entities” the prospectus and the prospectus supplement (found on page 66 of each) is replaced with the following:
Withholding on Certain Foreign Accounts and Entities. The Foreign Account Tax Compliance Act, or FATCA, imposes withholding taxes on “withholdable payments” (as defined below) made to “foreign financial institutions” and certain other non-U.S. entities unless (1) the foreign financial institution undertakes certain diligence and reporting obligations or (2) the foreign non-financial entity either certifies it does not have any substantial United States owners or furnishes identifying information regarding each substantial United States owner. “Withholdable payment” generally means any payment of interest, dividends, and certain other types of generally passive income if such payment is from sources within the United States. If the payee is a foreign financial institution, it must enter into an agreement with the United States Treasury requiring, among other things, that it undertakes to identify accounts held by certain United States persons or United States-owned foreign entities, annually report certain information about such accounts, and withhold 30% on payments to account holders whose actions prevent them from complying with these reporting and other requirements. Investors in jurisdictions that have entered into “intergovernmental agreements” may, in lieu of the foregoing requirements, be required to report such information to their home jurisdictions. Prospective investors should consult their tax advisors regarding this legislation.

Item 1A. Risk Factors.
Set forth below are the risks that we believe are material to our investors. We refer to the equity and debt securities of both BXP and BPLP as our “securities,” and the investors who own securities, or both, as our “securityholders.” This section contains forward-looking statements. You should refer to the explanation of the qualifications and limitations on forward-looking statements beginning on page 55.
Our performance and value are subject to risks associated with our real estate assets and with the real estate industry.
Our economic performance and the value of our real estate assets, and consequently the value of our securities, are subject to the risk that if our properties do not generate revenues sufficient to meet our operating expenses, including debt service and capital expenditures, our cash flow and ability to pay distributions to our securityholders will be adversely affected. The following factors, among others, may adversely affect the income generated by our properties:
downturns in the national, regional and local economic conditions (particularly increases in unemployment);
competition from other office, hotel, retail and residential buildings;
local real estate market conditions, such as oversupply or reduction in demand for office, hotel, retail or residential space;
changes in interest rates and availability of financing;
vacancies, changes in market rental rates and the need to periodically repair, renovate and re-let space;
changes in space utilization by our tenants due to technology, economic conditions and business culture;
increased operating costs, including insurance expense, utilities, real estate taxes, state and local taxes and heightened security costs;
civil disturbances, earthquakes and other natural disasters or terrorist acts or acts of war which may result in uninsured or underinsured losses or decrease the desirability to our tenants in impacted locations;
significant expenditures associated with each investment, such as debt service payments, real estate taxes (including reassessments and changes in tax laws), insurance and maintenance costs which are generally not reduced when circumstances cause a reduction in revenues from a property;
declines in the financial condition of our tenants and our ability to collect rents from our tenants; and
decreases in the underlying value of our real estate.
We are dependent upon the economic climates of our markets—Boston, Los Angeles, New York, San Francisco and Washington, DC.
Substantially all of our revenue is derived from properties located in five markets: Boston, Los Angeles, New York, San Francisco and Washington, DC. A downturn in the economies of these markets, or the impact that a downturn in the overall national economy may have upon these economies, could result in reduced demand for office space and/or a reduction in rents. Because our portfolio consists primarily of office buildings (as compared to a more diversified real estate portfolio), a decrease in demand for office space in turn could adversely affect our results of operations. Additionally, there are submarkets within our markets that are dependent upon a limited number of industries. For example, in our Washington, DC market, we focus on leasing office properties to governmental agencies and contractors, as well as legal firms. A reduction in spending by the federal government could result in reduced demand for office space and adversely affect our results of operations. In addition, in our New York market, we have historically leased properties to financial, legal and other professional firms. A significant downturn in one or more of these sectors could adversely affect our results of operations. 
In addition, a significant economic downturn over a period of time could result in an event or change in circumstances that results in an impairment in the value of our properties or our investments in unconsolidated joint ventures. An impairment loss is recognized if the carrying amount of the asset (1) is not recoverable over its expected holding period and (2) exceeds its fair value. There can be no assurance that we will not take charges in

19


the future related to the impairment of our assets or investments. Any future impairment could have a material adverse effect on our results of operations in the period in which the charge is taken.
Our actual costs to develop properties may exceed our budgeted costs.
We intend to continue to develop and substantially renovate office, retail and residential properties. Our current and future development and construction activities may be exposed to the following risks: 
we may be unable to proceed with the development of properties because we cannot obtain financing on favorable terms or at all;
we may incur construction costs for a development project that exceed our original estimates due to increases in interest rates and increased materials, labor, leasing or other costs, which could make completion of the project less profitable because market rents may not increase sufficiently to compensate for the increase in construction costs;
we may be unable to obtain, or face delays in obtaining, required zoning, land-use, building, occupancy, and other governmental permits and authorizations, which could result in increased costs and could require us to abandon our activities entirely with respect to a project;
we may abandon development opportunities after we begin to explore them and as a result we may lose deposits or fail to recover expenses already incurred;
we may expend funds on and devote management’s time to projects that we do not complete;
we may be unable to complete construction and/or leasing of a property on schedule or at all; and
we may suspend development projects after construction has begun due to changes in economic conditions or other factors, and this may result in the write-off of costs, payment of additional costs or increases in overall costs when the development project is restarted.
Investment returns from our developed properties may be less than anticipated. 
Our developed properties may be exposed to the following risks:
we may lease developed properties at rental rates that are less than the rates projected at the time we decide to undertake the development;
operating expenses and construction costs may be greater than projected at the time of development, resulting in our investment being less profitable than we expected; and
occupancy rates and rents at newly developed properties may fluctuate depending on a number of factors, including market and economic conditions, and may result in our investments being less profitable than we expected or not profitable at all.
We face risks associated with the development of mixed-use commercial properties.
We operate, are currently developing, and may in the future develop, properties either alone or through joint ventures with other persons that are known as “mixed-use” developments. This means that in addition to the development of office space, the project may also include space for residential, retail, hotel or other commercial purposes. We have less experience in developing and managing non-office and non-retail real estate than we do with office real estate. As a result, if a development project includes a non-office or non-retail use, we may seek to develop that component ourselves, sell the rights to that component to a third-party developer with experience in that use or we may seek to partner with such a developer. If we do not sell the rights or partner with such a developer, or if we choose to develop the other component ourselves, we would be exposed not only to those risks typically associated with the development of commercial real estate generally, but also to specific risks associated with the development and ownership of non-office and non-retail real estate. In addition, even if we sell the rights to develop the other component or elect to participate in the development through a joint venture, we may be exposed to the risks associated with the failure of the other party to complete the development as expected. These include the risk that the other party would default on its obligations necessitating that we complete the other component ourselves (including providing any necessary financing). In the case of residential properties, these risks include competition for prospective residents from other operators whose properties may be perceived to offer a better location or better amenities or whose rent may be perceived as a better value given the quality, location and

20


amenities that the resident seeks. We will also compete against condominiums and single-family homes that are for sale or rent. Because we have less experience with residential properties than with office and retail properties, we expect to retain third parties to manage our residential properties. If we decide to not sell or participate in a joint venture and instead hire a third party manager, we would be dependent on them and their key personnel who provide services to us and we may not find a suitable replacement if the management agreement is terminated, or if key personnel leave or otherwise become unavailable to us. 
Our properties face significant competition.
We face significant competition from developers, owners and managers of office and residential properties and other commercial real estate, including sublease space available from our tenants. Substantially all of our properties face competition from similar properties in the same market. This competition may affect our ability to attract and retain tenants and may reduce the rents we are able to charge. These competing properties may have vacancy rates higher than our properties, which may result in their owners being willing to lease available space at lower rates than the space in our properties.
We face potential difficulties or delays renewing leases or re-leasing space.
We derive most of our income from rent received from our tenants. If a tenant experiences a downturn in its business or other types of financial distress, including the costs of additional federal, state or local tax burdens, it may be unable to make timely rental payments. Also, when our tenants decide not to renew their leases or terminate early, we may not be able to re-let the space or there could be a substantial delay in re-letting the space. Even if tenants decide to renew or lease new space, the terms of renewals or new leases, including the cost of required renovations or concessions to tenants, may be less favorable to us than current lease terms. As a result, our cash flow could decrease and our ability to make distributions to our securityholders could be adversely affected.

Changes in rent control or rent stabilization and eviction laws and regulations in our markets could have a material adverse effect on our residential portfolio’s results of operations and residential property values.
Various state and local governments have enacted and may continue to enact rent control or rent stabilization laws and regulations or take other actions that could limit our ability to raise rents or charge certain fees such as pet fees or application fees. We have seen a recent increase in governments considering, or being urged by advocacy groups to consider, rent control or rent stabilization laws and regulations. Depending on the extent and terms of future enactments of rent control or rent stabilization laws and regulations, as well as any lawsuits against us arising from such issues, such future enactments could have a material adverse effect on our residential portfolio’s results of operations and the value of our residential properties.
State and local governments may also make changes to eviction and other tenants’ rights laws and regulations that could have a material adverse effect on our residential portfolio’s results of operations and the value of our residential properties. If we are restricted from re-leasing apartment units due to the inability to evict delinquent residents, our results of operations and property values for our residential properties may be adversely effected.
We face potential adverse effects from major tenants’ bankruptcies or insolvencies.
The bankruptcy or insolvency of a major tenant may adversely affect the income produced by our properties. Our tenants could file for bankruptcy protection or become insolvent in the future. We cannot evict a tenant solely because of its bankruptcy. On the other hand, a bankrupt tenant may reject and terminate its lease with us. In such case, our claim against the bankrupt tenant for unpaid and future rent would be subject to a statutory cap that might be substantially less than the remaining rent actually owed under the lease, and, even so, our claim for unpaid rent would likely not be paid in full. This shortfall could adversely affect our cash flow and results of operations.
We face the risk that third parties will not be able to service or repay loans we make to them.
From time to time, we have loaned and in the future may loan funds to (1) a third-party buyer to facilitate the sale of an asset by us to such third party, or (2) a third party in connection with the formation of a joint venture to acquire and/or develop a property. Making these loans subjects us to the following risks, each of which could have a material adverse effect on our cash flow, results of operations and/or financial condition:

21


the third party may be unable to make full and timely payments of interest and principal on the loan when due;
if the third-party buyer to whom we provide seller financing and utilizes the assets as collateral does not manage the property well, or the property otherwise fails to meet financial projections, performs poorly or declines in value, then the buyer may not have the funds or ability to raise new debt with which to make required payments of interest and principal to us;
if we loan funds to a joint venture, and the joint venture is unable to make required payments of interest or principal, or both, or there are disagreements with respect to the repayment of the loan or other matters, then we could have a resulting dispute with our partner(s), and such a dispute could harm our relationship(s) with our partner(s) and cause delays in developing or selling the property or the failure to properly manage the property; and
if we loan funds to a joint venture and the joint venture is unable to make required payments of interest and principal, or both, then we may exercise remedies available to us in the joint venture agreement that could allow us to increase our ownership interest or our control over major decisions, or both, which could result in an unconsolidated joint venture becoming consolidated with our financial statement; doing so could require us to reallocate the purchase price among the various asset and liability components and this could result in material changes to our reported results of operations and financial condition.
We face risks associated with the use of debt to fund acquisitions and developments, including refinancing risk. 
We are subject to the risks normally associated with debt financing, including the risk that our cash flow will be insufficient to meet required payments of principal and interest. We anticipate that only a small portion of the principal of our debt will be repaid prior to maturity. Therefore, we are likely to need to refinance at least a portion of our outstanding debt as it matures. There is a risk that we may not be able to refinance existing debt or that the terms of any refinancing will not be as favorable as the terms of our existing debt. If principal payments due at maturity cannot be refinanced, extended or repaid with proceeds from other sources, such as new equity capital, our cash flow may not be sufficient to repay all maturing debt in years when significant “balloon” payments come due. In addition, we may rely on debt to fund a portion of our new investments such as our acquisition and development activity. There is a risk that we may be unable to finance these activities on favorable terms or at all. These conditions, which increase the cost and reduce the availability of debt, may continue or worsen in the future. 
We have had and may have in the future agreements with a number of limited partners of BPLP who contributed properties in exchange for partnership interests that require BPLP to maintain for specified periods of time secured debt on certain of our assets and/or allocate partnership debt to such limited partners to enable them to continue to defer recognition of their taxable gain with respect to the contributed property. These tax protection and debt allocation agreements may restrict our ability to repay or refinance debt.  As of December 31, 2019, we had no tax protection or debt allocation agreement requirements that may restrict our ability to repay or finance debt.
Adverse economic and geopolitical conditions, health crises and dislocations in the credit markets could have a material adverse effect on our results of operations, financial condition and ability to pay distributions. 
Our business may be affected by market and economic challenges experienced by the U.S. and global economies or real estate industry as a whole, by the local economic conditions in the markets in which our properties are located, including the impact of high unemployment, volatility in the public equity and debt markets, and international economic and other conditions, including pandemics. These current conditions, or similar conditions existing in the future, may adversely affect our results of operations, financial condition and ability to pay distributions as a result of the following, among other potential consequences: 
the financial condition of our tenants, many of which are media and technology, financial, government, legal and other professional firms, may be adversely affected, which may result in tenant defaults under leases due to bankruptcy, lack of liquidity, lack of funding, operational failures or for other reasons;
significant job losses in the financial and professional services industries may occur, which may decrease demand for our office space, causing market rental rates and property values to be negatively impacted;

22


our ability to borrow on terms and conditions that we find acceptable, or at all, may be limited, which could reduce our ability to pursue acquisition and development opportunities and refinance existing debt, reduce our returns from our acquisition and development activities and increase our future interest expense;
reduced values of our properties may limit our ability to dispose of assets at attractive prices or to obtain debt financing secured by our properties and may reduce the availability of unsecured loans;
the value and liquidity of our short-term investments and cash deposits could be reduced as a result of a deterioration of the financial condition of the institutions that hold our cash deposits or the institutions or assets in which we have made short-term investments, a dislocation of the markets for our short-term investments, increased volatility in market rates for such investments or other factors;
one or more lenders under our line of credit could refuse to fund their financing commitment to us or could fail and we may not be able to replace the financing commitment of any such lenders on favorable terms, or at all; and
to the extent we enter into derivative financial instruments, one or more counterparties to our derivative financial instruments could default on their obligations to us, or could fail, increasing the risk that we may not realize the benefits of these instruments.
In addition, public health crises, pandemics and epidemics, such as those caused by the novel coronavirus (COVID-19), could have a material adverse effect on global, national and local economies, as well as on our business and our tenants’ businesses by disrupting supply chains and delaying transactional activities.  In addition to the potential consequences listed above, these same factors may cause prospective tenants to delay their leasing decisions or choose to lease less space.  The potential impact of a pandemic, epidemic or outbreak of a contagious disease on our tenants and our properties is difficult to predict, and they could have a material adverse effect on our results of operations and financial condition.
An increase in interest rates would increase our interest costs on variable rate debt and could adversely impact our ability to refinance existing debt or sell assets on favorable terms or at all. 
As of February 21, 2020, we had approximately $500 million of outstanding indebtedness, excluding our unconsolidated joint ventures, that bears interest at variable rates, and we may incur more indebtedness in the future. If interest rates increase, then so would the interest costs on our unhedged variable rate debt, which could adversely affect our cash flow and our ability to pay principal and interest on our debt and our ability to make distributions to our securityholders. Further, rising interest rates could limit our ability to refinance existing debt when it matures or significantly increase our future interest expense. From time to time, we enter into interest rate swap agreements and other interest rate hedging contracts, including swaps, caps and floors. While these agreements are intended to lessen the impact of rising interest rates on us, they also expose us to the risk that the other parties to the agreements will not perform, we could incur significant costs associated with the settlement of the agreements, the agreements will be unenforceable and the underlying transactions will fail to qualify as highly-effective cash flow hedges under guidance included in ASC 815 “Derivatives and Hedging.” In addition, an increase in interest rates could decrease the amounts third-parties are willing to pay for our assets, thereby limiting our ability to change our portfolio promptly in response to changes in economic or other conditions. 
We may be adversely affected by the potential discontinuation of LIBOR. 
In July 2017, the Financial Conduct Authority (the “FCA”) announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference Rates Committee which identified the Secured Overnight Financing Rate (“SOFR”) as its preferred alternative to USD-LIBOR. We are not able to predict when LIBOR will cease to be published or precisely how SOFR will be calculated and published. Any changes adopted by the FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in its current form.
We have contracts that are indexed to LIBOR and are monitoring and evaluating the related risks, which include interest amounts on our variable rate debt, our unconsolidated joint ventures’ variable rate debt and the swap rate for our unconsolidated joint ventures’ interest rate swaps. In the event that LIBOR is discontinued, the interest rates will be based on an alternative variable rate specified in the applicable documentation governing such

23


debt or swaps or as otherwise agreed upon. Such an event would not affect our ability to borrow or maintain already outstanding borrowings or swaps, but the alternative variable rate could be higher and more volatile than LIBOR prior to its discontinuance. 
Certain risks arise in connection with transitioning contracts to an alternative variable rate, including any resulting value transfer that may occur. The value of loans, securities, or derivative instruments tied to LIBOR could also be impacted if LIBOR is limited or discontinued. For some instruments, the method of transitioning to an alternative rate may be challenging, as they may require substantial negotiation with each respective counterparty. If a contract is not transitioned to an alternative variable rate and LIBOR is discontinued, the impact is likely to vary by contract. If LIBOR is discontinued or if the method of calculating LIBOR changes from its current form, interest rates on our current or future indebtedness may be adversely affected.
While we expect LIBOR to be available in substantially its current form until the end of 2021, it is possible that LIBOR will become unavailable prior to that point. This could result, for example, if sufficient banks decline to make submissions to the LIBOR administrator. In that case, the risks associated with the transition to an alternative variable rate will be accelerated and magnified.
Covenants in our debt agreements could adversely affect our financial condition.
The mortgages on our properties contain customary covenants such as those that limit our ability, without the prior consent of the lender, to further mortgage the applicable property or to modify or discontinue insurance coverage. Our unsecured credit facility, unsecured debt securities and certain secured loans contain customary restrictions, requirements and other limitations on our ability to incur indebtedness, including total debt to asset ratios, secured debt to total asset ratios, debt service coverage ratios and minimum ratios of unencumbered assets to unsecured debt, which we must maintain. Our continued ability to borrow under our credit facilities is subject to compliance with our financial and other covenants. In addition, our failure to comply with such covenants could cause a default under the applicable debt agreement, and we may then be required to repay such debt with capital from other sources. Under those circumstances, other sources of capital may not be available to us, or be available only on unattractive terms. Additionally, in the future our ability to satisfy current or prospective lenders’ insurance requirements may be adversely affected if lenders generally insist upon greater insurance coverage against acts of terrorism or losses resulting from earthquakes than is available to us in the marketplace or on commercially reasonable terms. 
We rely on debt financing, including borrowings under our unsecured credit facility, issuances of unsecured debt securities and debt secured by individual properties, to finance our existing portfolio, our acquisition and development activities and for working capital. If we are unable to obtain debt financing from these or other sources, or to refinance existing indebtedness upon maturity, our financial condition and results of operations would likely be adversely affected. If we breach covenants in our debt agreements, the lenders can declare a default and, if the debt is secured, can take possession of the property securing the defaulted loan. In addition, our unsecured debt agreements contain specific cross-default provisions with respect to specified other indebtedness, giving the unsecured lenders the right to declare a default if we are in default under other loans in some circumstances. Defaults under our debt agreements could materially and adversely affect our financial condition and results of operations. 
Our degree of leverage could limit our ability to obtain additional financing or affect the market price of our equity and debt securities. 
As of February 21, 2020, our Consolidated Debt was approximately $11.9 billion (excluding unconsolidated joint venture debt).

Our degree of leverage could affect our ability to obtain additional financing for working capital, capital expenditures, acquisitions, development or other general corporate purposes. Our senior unsecured debt is currently rated investment grade by two major rating agencies. However, there can be no assurance that we will be able to maintain this rating, and in the event our senior debt is downgraded from its current rating, we would likely incur higher borrowing costs and/or difficulty in obtaining additional financing. Our degree of leverage could also make us more vulnerable to a downturn in business or the economy generally. There is a risk that changes in our debt to market capitalization ratio, which is in part a function of BXP’s stock price, or BPLP’s ratio of indebtedness to other measures of asset value used by financial analysts may have an adverse effect on the market price of our equity or debt securities. 
We face risks associated with property acquisitions. 
We have acquired in the past and intend to continue to pursue the acquisition of properties and portfolios of properties, including large portfolios that could increase our size and result in alterations to our capital structure. Our acquisition activities and their success are subject to the following risks: 
even if we enter into an acquisition agreement for a property, we may be unable to complete that acquisition after making a non-refundable deposit and incurring certain other acquisition-related costs;
we may be unable to obtain or assume financing for acquisitions on favorable terms or at all;
acquired properties may fail to perform as expected;
the actual costs of repositioning, redeveloping or maintaining acquired properties may be greater than our estimates;
the acquisition agreement will likely contain conditions to closing, including completion of due diligence investigations to our satisfaction or other conditions that are not within our control, which may not be satisfied;
acquired properties may be located in new markets, either within or outside the United States, where we may face risks associated with a lack of market knowledge or understanding of the local economy, lack of business relationships in the area, costs associated with opening a new regional office and unfamiliarity with local governmental and permitting procedures;

25


we may acquire real estate through the acquisition of the ownership entity subjecting us to the risks of that entity; and
we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties, into our existing operations, and this could have an adverse effect on our results of operations and financial condition.
We have acquired in the past and in the future may acquire properties through the acquisition of first mortgage or mezzanine debt. Investments in these loans must be carefully structured to ensure that BXP continues to satisfy the various asset and income requirements applicable to REITs. If we fail to structure any such acquisition properly, BXP could fail to qualify as a REIT. In addition, acquisitions of first mortgage or mezzanine loans subject us to the risks associated with the borrower’s default, including potential bankruptcy, and there may be significant delays and costs associated with the process of foreclosure on collateral securing or supporting these investments.  There can be no assurance that we would recover any or all of our investment in the event of such a default or bankruptcy. 
We have acquired in the past and in the future may acquire properties or portfolios of properties through tax deferred contribution transactions in exchange for partnership interests in BPLP. This acquisition structure has the effect, among others, of reducing the amount of tax depreciation we can deduct over the tax life of the acquired properties, and typically requires that we agree to protect the contributors’ ability to defer recognition of taxable gain through restrictions on our ability to dispose of the acquired properties and/or the allocation of partnership debt to the contributors to maintain their tax bases. These restrictions could limit our ability to sell an asset at a time, or on terms, that would be favorable absent such restrictions. 
Acquired properties may expose us to unknown liability. 
We may acquire properties or invest in joint ventures that own properties subject to liabilities and without any recourse, or with only limited recourse, against the prior owners or other third parties with respect to unknown liabilities. As a result, if a liability were asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle or contest it, which could adversely affect our results of operations and cash flow. Unknown liabilities with respect to acquired properties might include: 
liabilities for clean-up of undisclosed environmental contamination;
claims by tenants, vendors or other persons against the former owners of the properties;
liabilities incurred in the ordinary course of business; and
claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties.
Competition for acquisitions may result in increased prices for properties. 
We plan to continue to acquire properties as we are presented with attractive opportunities. We may face competition for acquisition opportunities with other investors, and this competition may adversely affect us by subjecting us to the following risks: 
we may be unable to acquire a desired property because of competition from other well-capitalized real estate investors, including publicly traded and private REITs, institutional investment funds and other real estate investors; and
even if we are able to acquire a desired property, competition from other real estate investors may significantly increase the purchase price.
Any future international activities will be subject to special risks and we may not be able to effectively manage our international business. 
We have underwritten, and in the future may acquire, properties, portfolios of properties or interests in real estate-related entities on a strategic or selective basis in international markets that are new to us. If we acquire properties or platforms located in these markets, we will face risks associated with a lack of market knowledge and understanding of the local economy, forging new business relationships in the area and unfamiliarity with local laws and government and permitting procedures. In addition, our international operations will be subject to the usual risks of doing business abroad such as possible revisions in tax treaties or other laws and regulations, including those governing the taxation of our international income, restrictions on the transfer of funds and uncertainty over

26


terrorist activities. We cannot predict the likelihood that any of these developments may occur. Further, we may in the future enter into agreements with non-U.S. entities that are governed by the laws of, and are subject to dispute resolution in the courts of, another country or region. We cannot accurately predict whether such a forum would provide us with an effective and efficient means of resolving disputes that may arise. 
Investments in international markets may also subject us to risks associated with funding increasing headcount, integrating new offices, and establishing effective controls and procedures to regulate the operations of new offices and to monitor compliance with U.S. laws and regulations such as the Foreign Corrupt Practices Act and similar foreign laws and regulations, such as the U.K. Bribery Act.
We may be subject to risks from potential fluctuations in exchange rates between the U.S. dollar and the currencies of the other countries in which we invest. 
If we invest in countries where the U.S. dollar is not the national currency, we will be subject to international currency risks from the potential fluctuations in exchange rates between the U.S. dollar and the currencies of those other countries. A significant depreciation in the value of the currency of one or more countries where we have a significant investment may materially affect our results of operations. We may attempt to mitigate any such effects by borrowing in the currency of the country in which we are investing and, under certain circumstances, by hedging exchange rate fluctuations; however, access to capital may be more restricted, or unavailable on favorable terms or at all, in certain locations. For leases denominated in international currencies, we may use derivative financial instruments to manage the international currency exchange risk. We cannot assure you, however, that our efforts will successfully neutralize all international currency risks. 
Our use of joint ventures may limit our flexibility with jointly owned investments.
In appropriate circumstances, we intend to develop, acquire and recapitalize properties in joint ventures with other persons or entities. We currently have joint ventures that are and are not consolidated within our financial statements. Our participation in joint ventures subjects us to risks, including but not limited to, the following risks that: 
we could become engaged in a dispute with any of our joint venture partners that might affect our ability to develop, finance or operate a property and could lead to the sale of either parties’ ownership interest or the property;
some of our joint ventures are subject to debt and in the current credit markets the refinancing of such debt may require equity capital calls;
our joint venture partners may default on their obligations necessitating that we fulfill their obligation ourselves;
our joint venture partners may have different objectives than we have regarding the appropriate timing and terms of any sale or refinancing of properties or the commencement of development activities;
our joint venture partners may be structured differently than us for tax purposes and this could create conflicts of interest;
our joint venture partners may have competing interests in our markets that could create conflicts of interest;
our joint ventures may be unable to repay any amounts that we may loan to them; and
our joint venture agreements may contain provisions limiting the liquidity of our interest for sale or sale of the entire asset.
We may have difficulty selling our properties, which may limit our flexibility. 
Properties like the ones that we own could be difficult to sell. This may limit our ability to change our portfolio promptly in response to changes in economic or other conditions. In addition, federal tax laws limit our ability to sell properties and this may affect our ability to sell properties without adversely affecting returns to our securityholders. These restrictions reduce our ability to respond to changes in the performance of our investments and could adversely affect our financial condition and results of operations. 

27


Our ability to dispose of some of our properties is constrained by their tax attributes. Properties which we developed and have owned for a significant period of time or which we acquired through tax deferred contribution transactions in exchange for partnership interests in BPLP often have low tax bases. Furthermore, as a REIT, BXP may be subject to a 100% “prohibited transactions” tax on the gain from dispositions of property if BXP is deemed to hold the property primarily for sale to customers in the ordinary course of business, unless the disposition qualifies under a safe harbor exception for properties that have been held for at least two years and with respect to which certain other requirements are met. The potential application of the prohibited transactions tax could cause us to forego potential dispositions of property or other opportunities that might otherwise be attractive to us, or to undertake such dispositions or other opportunities through a taxable REIT subsidiary, which would generally result in income taxes being incurred. If we dispose of these properties outright in taxable transactions, we may be required to distribute a significant amount of the taxable gain to our securityholders under the requirements of the Internal Revenue Code for REITs, which in turn would impact our future cash flow and may increase our leverage. In some cases, without incurring additional costs we may be restricted from disposing of properties contributed in exchange for our partnership interests under tax protection agreements with contributors. To dispose of low basis or tax-protected properties efficiently we from time to time use like-kind exchanges, which are intended to qualify for non-recognition of taxable gain, but can be difficult to consummate and result in the property for which the disposed assets are exchanged inheriting their low tax bases and other tax attributes (including tax protection covenants). 
Conflicts of interest exist with holders of interests in BPLP. 
Sales of properties and repayment of related indebtedness will have different effects on holders of interests in BPLP than on BXP’s stockholders. 
Some holders of interests in BPLP could incur adverse tax consequences upon the sale of certain of our properties and on the repayment of related debt which differ from the tax consequences to BXP and its stockholders. Consequently, such holders of partnership interests in BPLP may have different objectives regarding the appropriate pricing and timing of any such sale or repayment of debt. While BXP has exclusive authority under the limited partnership agreement of BPLP to determine when to refinance or repay debt or whether, when, and on what terms to sell a property, subject, in the case of certain properties, to the contractual commitments described below, any such decision would require the approval of BXP’s Board of Directors. While the Board of Directors has a policy with respect to these matters directors and executive officers could exercise their influence in a manner inconsistent with the interests of some, or a majority, of BXP’s stockholders, including in a manner which could prevent completion of a sale of a property or the repayment of indebtedness.
Agreement not to sell some properties. 
We have had and may have in the future agreements with the contributors of some properties that we have acquired in exchange for partnership interests in BPLP pursuant to which we have agreed not to sell or otherwise transfer the properties, prior to specified dates, in any transaction that would trigger taxable income to the contributor. In addition, we are responsible for the reimbursement of certain tax-related costs to the prior owners if the subject properties are sold in a taxable sale. In general, our obligations to the prior owners are limited in time and only apply to actual damages suffered.
Also, BPLP has had and may have in the future agreements providing prior owners of properties with the right to guarantee specific amounts of indebtedness and, in the event that the specific indebtedness they guarantee is repaid or reduced, additional and/or substitute indebtedness. These agreements may hinder actions that BPLP may otherwise desire to take to repay or refinance guaranteed indebtedness because BPLP would be required to make payments to the beneficiaries of such agreements if it violates these agreements.
Because we own a hotel property, we face the risks associated with the hospitality industry. 
The following factors, among others, are common to the hotel industry, and may reduce the receipts generated by our hotel property: 
our hotel property competes for guests with other hotels, a number of which may have greater marketing and financial resources than our hotel-operating business partners;
if there is an increase in operating costs resulting from inflation and other factors, our hotel-operating business partners may not be able to offset such increase by increasing room rates;
our hotel property is subject to the fluctuating and seasonal demands of business travelers and tourism; and

28


our hotel property is subject to general and local economic and social conditions that may affect demand for travel in general, including war and terrorism.
In addition, because our hotel property is located in Cambridge, Massachusetts, it is subject to the Cambridge market’s fluctuations in demand, increases in operating costs and increased competition from additions in supply.
We face risks associated with short-term liquid investments. 
We may invest cash balances in a variety of short-term investments that are intended to preserve principal value and maintain a high degree of liquidity while providing current income. From time to time, these investments may include (either directly or indirectly): 
direct obligations issued by the U.S. Treasury;
obligations issued or guaranteed by the U.S. Government or its agencies;
taxable municipal securities;
obligations (including certificates of deposit) of banks and thrifts;
commercial paper and other instruments consisting of short-term U.S. dollar denominated obligations issued by corporations and banks;
repurchase agreements collateralized by corporate and asset-backed obligations;
both registered and unregistered money market funds; and
other highly rated short-term securities.
Investments in these securities and funds are not insured against loss of principal. Under certain circumstances we may be required to redeem all or part of our investment, and our right to redeem some or all of our investment may be delayed or suspended. In addition, there is no guarantee that our investments in these securities or funds will be redeemable at par value. A decline in the value of our investment or a delay or suspension of our right to redeem may have a material adverse effect on our results of operations or financial condition. 
Our success depends on key personnel whose continued service is not guaranteed. 
We depend on the efforts of key personnel, particularly Owen D. Thomas, Chief Executive Officer, Douglas T. Linde, President, and Raymond A. Ritchey, Senior Executive Vice President. Among the reasons that Messrs. Thomas, Linde and Ritchey are important to our success is that each has a national reputation, which attracts business and investment opportunities and assists us in negotiations with lenders, joint venture partners and other investors. If we lost their services, our relationships with lenders, potential tenants and industry personnel could diminish.  
Our Chief Financial Officer and Regional Managers also have strong reputations. Their reputations aid us in identifying opportunities, having opportunities brought to us, and negotiating with tenants and build-to-suit prospects. While we believe that we could find replacements for these key personnel, the loss of their services could materially and adversely affect our operations because of diminished relationships with lenders, prospective tenants and industry personnel. 
Compliance or failure to comply with the Americans with Disabilities Act or other safety regulations and requirements could result in substantial costs. 
The Americans with Disabilities Act generally requires that certain buildings, including office buildings, residential buildings and hotels, be made accessible to disabled persons. Noncompliance could result in the imposition of fines by the federal government or the award of damages to private litigants. If, under the Americans with Disabilities Act, we are required to make substantial alterations and capital expenditures in one or more of our properties, including the removal of access barriers, it could adversely affect our financial condition and results of operations, as well as the amount of cash available for distribution to our securityholders. 

29


Our properties are subject to various federal, state and local regulatory requirements, such as state and local fire and life safety requirements. If we fail to comply with these requirements, we could incur fines or private damage awards. We do not know whether existing requirements will change or whether compliance with future requirements will require significant unanticipated expenditures that will affect our cash flow and results of operations. 
Failure to comply with Federal Government contractor requirements could result in substantial costs and loss of substantial revenue. 
As of December 31, 2019, the U.S. Government was our largest tenant by square feet. We are subject to compliance with a wide variety of complex legal requirements because we are a Federal Government contractor. These laws regulate how we conduct business, require us to administer various compliance programs and require us to impose compliance responsibilities on some of our contractors. Our failure to comply with these laws could subject us to fines, penalties and damages, cause us to be in default of our leases and other contracts with the Federal Government and bar us from entering into future leases and other contracts with the Federal Government. There can be no assurance that these costs and loss of revenue will not have a material adverse effect on our properties, operations or business.
Some potential losses are not covered by insurance. 
Our property insurance program per occurrence limits are $1.0 billion for its portfolio insurance program, including coverage for acts of terrorism other than nuclear, biological, chemical or radiological terrorism (“Terrorism Coverage”). We also carry $250 million of Terrorism Coverage for 601 Lexington Avenue, New York, New York (“601 Lexington Avenue”) in excess of the $1.0 billion of coverage in our property insurance program. Certain properties, including the General Motors Building located at 767 Fifth Avenue in New York, New York (“767 Fifth Avenue”), are currently insured in separate insurance programs. The property insurance program per occurrence limits for 767 Fifth Avenue are $1.625 billion, including Terrorism Coverage. We also currently carry nuclear, biological, chemical and radiological terrorism insurance coverage for acts of terrorism certified under the Federal Terrorism Risk Insurance Act (as amended, “TRIA”) (“NBCR Coverage”), which is provided by IXP as a direct insurer, for the properties in our portfolio, including 767 Fifth Avenue, but excluding certain other properties owned in joint ventures with third parties or which we manage. The per occurrence limit for NBCR Coverage is $1.0 billion. Under TRIA, after the payment of the required deductible and coinsurance, the NBCR Coverage provided by IXP is backstopped by the Federal Government if the aggregate industry insured losses resulting from a certified act of terrorism exceed a “program trigger.” In 2019, the program trigger was $180 million and the coinsurance was 19%, however, both will increase in subsequent years pursuant to TRIA. If the Federal Government pays out for a loss under TRIA, it is mandatory that the Federal Government recoup the full amount of the loss from insurers offering TRIA coverage after the payment of the loss pursuant to a formula in TRIA. We may elect to terminate the NBCR Coverage if the Federal Government seeks recoupment for losses paid under TRIA, if TRIA is not extended after its expiration on December 31, 2027, if there is a change in our portfolio or for any other reason. We intend to continue to monitor the scope, nature and cost of available terrorism insurance.
We also currently carry earthquake insurance on our properties located in areas known to be subject to earthquakes. In addition, this insurance is subject to a deductible in the amount of 3% of the value of the affected property. Specifically, we currently carry earthquake insurance which covers our San Francisco and Los Angeles regions with a $240 million per occurrence limit and a $240 million annual aggregate limit, $20 million of which is provided by IXP, as a direct insurer. The amount of our earthquake insurance coverage may not be sufficient to cover losses from earthquakes. In addition, the amount of earthquake coverage could impact our ability to finance properties subject to earthquake risk. We may discontinue earthquake insurance or change the structure of our earthquake insurance program on some or all of our properties in the future if the premiums exceed our estimation of the value of the coverage.
IXP, a captive insurance company which is a wholly-owned subsidiary, acts as a direct insurer with respect to a portion of our earthquake insurance coverage for our Greater San Francisco and Los Angeles properties and our NBCR Coverage. Insofar as we own IXP, we are responsible for its liquidity and capital resources, and the accounts of IXP are part of our consolidated financial statements. In particular, if a loss occurs which is covered by our NBCR Coverage but is less than the applicable program trigger under TRIA, IXP would be responsible for the full amount of the loss without any backstop by the Federal Government. IXP would also be responsible for any recoupment charges by the Federal Government in the event losses are paid out and its insurance policy is maintained after the payout by the Federal Government. If we experience a loss and IXP is required to pay under its insurance policy, we would ultimately record the loss to the extent of the required payment. Therefore, insurance

30


coverage provided by IXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance. In addition, BPLP has issued a guarantee to cover liabilities of IXP in the amount of $20.0 million.
We continue to monitor the state of the insurance market in general, and the scope and costs of coverage for acts of terrorism and California earthquake risk in particular, but we cannot anticipate what coverage will be available on commercially reasonable terms in future policy years. There are other types of losses, such as from wars, for which we cannot obtain insurance at all or at a reasonable cost. With respect to such losses and losses from acts of terrorism, earthquakes or other catastrophic events, if we experience a loss that is uninsured or that exceeds policy limits, we could lose the capital invested in the damaged properties, as well as the anticipated future revenues from those properties. Depending on the specific circumstances of each affected property, it is possible that we could be liable for mortgage indebtedness or other obligations related to the property. Any such loss could materially and adversely affect our business and financial condition and results of operations.
Actual or threatened terrorist attacks may adversely affect our ability to generate revenues and the value of our properties. 
We have significant investments in large metropolitan markets that have been or may be in the future the targets of actual or threatened terrorism attacks, including Boston, Los Angeles, New York, San Francisco and Washington, DC. As a result, some tenants in these markets may choose to relocate their businesses to other markets or to lower-profile office buildings within these markets that may be perceived to be less likely targets of future terrorist activity. This could result in an overall decrease in the demand for office space in these markets generally or in our properties in particular, which could increase vacancies in our properties or necessitate that we lease our properties on less favorable terms or both. In addition, future terrorist attacks in these markets could directly or indirectly damage our properties, both physically and financially, or cause losses that materially exceed our insurance coverage. As a result of the foregoing, our ability to generate revenues and the value of our properties could decline materially. See also “—Some potential losses are not covered by insurance.” 
We face risks associated with our tenants and contractual counterparties being designated “Prohibited Persons” by the Office of Foreign Assets Control. 
Pursuant to Executive Order 13224 and other laws, the Office of Foreign Assets Control of the United States Department of the Treasury (“OFAC”) maintains a list of persons designated as terrorists or who are otherwise blocked or banned (“Prohibited Persons”). OFAC regulations and other laws prohibit conducting business or engaging in transactions with Prohibited Persons (the “OFAC Requirements”). Certain of our loan and other agreements require us to comply with OFAC Requirements. We have established a compliance program whereby tenants and others with whom we conduct business are checked against the OFAC list of Prohibited Persons prior to entering into any agreement and on a periodic basis thereafter. Our leases and other agreements, in general, require the other party to comply with OFAC Requirements. If a tenant or other party with whom we contract is placed on the OFAC list we may be required by the OFAC Requirements to terminate the lease or other agreement. Any such termination could result in a loss of revenue or a damage claim by the other party that the termination was wrongful. 
We face possible risks associated with the physical effects of climate change. 
The physical effects of climate change could have a material adverse effect on our properties, operations and business. For example, many of our properties are located along the East and West coasts, particularly those in the central business districts of Boston, Los Angeles, New York, San Francisco and Washington, DC. To the extent climate change causes changes in weather patterns, our markets could experience increases in storm intensity, extreme temperatures, rising sea-levels and/or drought. Over time, these conditions could result in declining demand for office space in our buildings or costs associated with infrastructure-related remediation projects. Climate change may also have indirect effects on our business by making property insurance unavailable or by increasing the cost of (i) property insurance on terms we find acceptable, (ii) real estate taxes or other assessments, (iii) energy and (iv) snow removal at our properties. There can be no assurance that climate change will not have a material adverse effect on our properties, operations or business.

Business—Business and Growth Strategies—Policies with Respect to Certain Activities—Sustainability” and our annual sustainability report available on our website at http://www.bxp.com under the heading “Sustainability.”

Potential liability for environmental contamination could result in substantial costs.
Under federal, state and local environmental laws, ordinances and regulations, we may be required to investigate and clean up the effects of releases of hazardous or toxic substances or petroleum products at or migrating from our properties simply because of our current or past ownership or operation of the real estate. If unidentified environmental problems arise, we may have to make substantial payments, which could adversely affect our cash flow and our ability to make distributions to our securityholders, because: as owner or operator we may have to pay for property damage and for investigation and clean-up costs incurred in connection with the contamination; the law typically imposes clean-up responsibility and liability regardless of whether the owner or operator knew of or caused the contamination; even if more than one person may be responsible for the contamination, each person who shares legal liability under the environmental laws may be held responsible for all of the clean-up costs; and governmental entities and third parties may sue the owner or operator of a contaminated site for damages and costs.
These costs could be substantial and in extreme cases could exceed the amount of our insurance or the value of the contaminated property. We currently carry environmental insurance in an amount and subject to deductibles that we believe are commercially reasonable. Specifically, we carry a pollution legal liability policy with a $20 million limit per incident and a policy aggregate limit of $40 million. The presence or migration of hazardous or toxic substances or petroleum products or the failure to properly remediate contamination may give rise to third-party claims for bodily injury, property damage and/or response costs and may materially and adversely affect our ability to borrow against, sell or rent an affected property. In addition, applicable environmental laws create liens on contaminated sites in favor of the government for damages and costs it incurs in connection with contamination. Changes in laws, regulations and practices and their implementation increasing the potential liability for environmental conditions existing at our properties, or increasing the restrictions on the handling, storage or discharge of hazardous or toxic substances or petroleum products or other actions may result in significant unanticipated expenditures.
Environmental laws also govern the presence, maintenance and removal of asbestos and other building materials. For example, laws require that owners or operators of buildings containing asbestos: 
properly manage and maintain the asbestos;
notify and train those who may come into contact with asbestos; and
undertake special precautions, including removal or other abatement, if asbestos would be disturbed during renovation or demolition of a building.
Such laws may impose fines and penalties on building owners or operators who fail to comply with these requirements and may allow third parties to seek recovery from owners or operators for personal injury associated with exposure to asbestos fibers. 
Some of our properties are located in urban and previously developed areas where fill or current or historic industrial uses of the areas have caused site contamination. It is our policy to retain independent environmental consultants to conduct or update Phase I environmental site assessments and asbestos surveys with respect to our acquisition of properties. These assessments generally include a visual inspection of the properties and the surrounding areas, an examination of current and historical uses of the properties and the surrounding areas and a review of relevant state, federal and historical documents, but do not involve invasive techniques such as soil and ground water sampling. Where appropriate, on a property-by-property basis, our practice is to have these consultants conduct additional testing, including sampling for asbestos, for lead and other contaminants in drinking water and, for soil and/or groundwater contamination where underground storage tanks are or were located or where other past site usage creates a potential environmental problem. Even though these environmental assessments are conducted, there is still the risk that: 
the environmental assessments and updates did not identify or properly address all potential environmental liabilities;
a prior owner created a material environmental condition that is not known to us or the independent consultants preparing the assessments;
new environmental liabilities have developed since the environmental assessments were conducted; and

32


future uses or conditions such as changes in applicable environmental laws and regulations could result in environmental liability for us.
Inquiries about indoor air quality may necessitate special investigation and, depending on the results, remediation beyond our regular indoor air quality testing and maintenance programs. Indoor air quality issues can stem from inadequate ventilation, chemical contaminants from indoor or outdoor sources, and biological contaminants such as molds, pollen, viruses and bacteria. Indoor exposure to chemical or biological contaminants above certain levels can be alleged to be connected to allergic reactions or other health effects and symptoms in susceptible individuals. If these conditions were to occur at one of our properties, we may be subject to third-party claims for personal injury, or may need to undertake a targeted remediation program, including without limitation, steps to increase indoor ventilation rates and eliminate sources of contaminants. Such remediation programs could be costly, necessitate the temporary relocation of some or all of the property’s tenants or require rehabilitation of the affected property. 
We face risks associated with security breaches through cyber attacks, cyber intrusions or otherwise, as well as other significant disruptions of our information technology (IT) networks and related systems. 
We face risks associated with security breaches, whether through cyber attacks or cyber intrusions over the Internet, malware, computer viruses, attachments to e-mails, persons inside our organization or persons with access to systems inside our organization, and other significant disruptions of our IT networks and related systems. The risk of a security breach or disruption, particularly through cyber attack or cyber intrusion, including by computer hackers, foreign governments and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. Our IT networks and related systems are essential to the operation of our business and our ability to perform day-to-day operations (including managing our building systems) and, in some cases, may be critical to the operations of certain of our tenants. Although we make efforts to maintain the security and integrity of these types of IT networks and related systems, and we have implemented various measures to manage the risk of a security breach or disruption, there can be no assurance that our security efforts and measures will be effective or that attempted security breaches or disruptions would not be successful or damaging. Even the most well-protected information, networks, systems and facilities remain potentially vulnerable because the techniques used in such attempted security breaches evolve and generally are not recognized until launched against a target, and in some cases, are designed not be detected and, in fact, may not be detected. Accordingly, we may be unable to anticipate these techniques or to implement adequate security barriers or other preventative measures, and thus it is impossible for us to entirely mitigate this risk. 
A security breach or other significant disruption involving our IT networks and related systems could: 
disrupt the proper functioning of our networks and systems and therefore our operations and/or those of certain of our tenants;
result in misstated financial reports, violations of loan covenants, missed reporting deadlines and/or missed permitting deadlines;
result in our inability to properly monitor our compliance with the rules and regulations regarding BXP’s qualification as a REIT;
result in the unauthorized access to, and destruction, loss, theft, misappropriation or release of, proprietary, confidential, sensitive or otherwise valuable information of ours or others, which others could use to compete against us or which could expose us to damage claims by third-parties for disruptive, destructive or otherwise harmful purposes and outcomes;
result in our inability to maintain the building systems relied upon by our tenants for the efficient use of their leased space;
require significant management attention and resources to remedy any damages that result;
subject us to claims for breach of contract, damages, credits, penalties or termination of leases or other agreements; and
damage our reputation among our tenants and investors generally.

33


Any or all of the foregoing could have a material adverse effect on our results of operations, financial condition and cash flows.
We did not obtain new owner’s title insurance policies in connection with properties acquired during BXP’s initial public offering. 
We acquired many of our properties from our predecessors at the completion of BXP’s initial public offering in June 1997. Before we acquired these properties, each of them was insured by a title insurance policy. We did not obtain new owner’s title insurance policies in connection with the acquisition of these properties. To the extent we have financed properties after acquiring them in connection with the initial public offering, we have obtained new title insurance policies, however, the amount of these policies may be less than the current or future value of the applicable properties. Nevertheless, because in many instances we acquired these properties indirectly by acquiring ownership of the entity that owned the property and those owners remain in existence as our subsidiaries, some of these title insurance policies may continue to benefit us. Many of these title insurance policies may be for amounts less than the current or future values of the applicable properties. If there was a title defect related to any of these properties, or to any of the properties acquired at the time of the initial public offering of BXP, that is no longer covered by a title insurance policy, we could lose both our capital invested in and our anticipated profits from such property. We have obtained title insurance policies for all properties that we have acquired after the initial public offering of BXP, however, these policies may be for amounts less than the current or future values of the applicable properties. 
We may be subject to adverse legislative or regulatory tax changes that could negatively impact our financial condition.
At any time, the U.S. federal income tax laws governing REITs or the administrative interpretations of those laws may be amended, including with respect to our hotel ownership structure. We cannot predict if or when any new U.S. federal income tax law, regulation, or administrative interpretation, or any amendment to any existing U.S. federal income tax law, Treasury regulation or administrative interpretation, will be adopted, promulgated or become effective and any such law, regulation, or interpretation may take effect retroactively. BXP, its taxable REIT subsidiaries, and our securityholders could be adversely affected by any such change in, or any new, U.S. federal income tax law, Treasury regulation or administrative interpretation.
The Tax Cuts and Jobs Act of 2017 (the “TCJA”), signed into law on December 22, 2017, represents sweeping tax reform legislation that makes significant changes to corporate and individual tax rates and the calculation of taxes.  While we currently do not expect the TCJA will have a significant direct impact on us, it may impact us indirectly as our tenants and the jurisdictions in which we do business as well as the overall investment thesis for REITs may be impacted both positively and negatively in ways that are difficult to predict. Additionally, the overall impact of the TCJA depends on future interpretations and regulations that may be issued by federal tax authorities, as well as changes in state and local taxation in response to the TCJA, and it is possible that such future interpretations, regulations and other changes could adversely impact us.
We face possible adverse state local tax audits and changes in state and local tax law.
Because BXP is organized and qualifies as a REIT, it is generally not subject to federal income taxes, but we are subject to certain state and local taxes. In the normal course of business, certain entities through which we own real estate either have undergone, or are currently undergoing, tax audits. Although we believe that we have substantial arguments in favor of our positions in the ongoing audits, in some instances there is no controlling precedent or interpretive guidance on the specific point at issue. Collectively, tax deficiency notices received to date from the jurisdictions conducting the ongoing audits have not been material. However, there can be no assurance that future audits will not occur with increased frequency or that the ultimate result of such audits will not have a material adverse effect on our results of operations.
From time to time changes in state and local tax laws or regulations are enacted, which may result in an increase in our tax liability. A shortfall in tax revenues for states and municipalities in which we operate may lead to an increase in the frequency and size of such changes. If such changes occur, we may be required to pay additional taxes on our assets or income. These increased tax costs could adversely affect our financial condition and results of operations and the amount of cash available for the payment of dividends and distributions to our securityholders. 

34


Litigation could have a material adverse effect.
From time to time, we are involved in legal proceedings and other claims. We may also be named as defendants in lawsuits allegedly arising out of our actions or the actions of our vendors, contractors, tenants or other contractual parties in which such parties have agreed to indemnify, defend and hold us harmless from and against various claims, litigation and liabilities arising in connection with their respective businesses and/or added as an additional insured under certain insurance policies. An unfavorable resolution of any legal proceeding or other claim could have a material adverse effect on our financial condition or results from operations. Regardless of its outcome, legal proceedings and other claims may result in substantial costs and expenses and significantly divert the attention of our management. With respect to any legal proceeding or other claim, there can be no assurance that we will be able to prevail, or achieve a favorable settlement or outcome, or that our insurance or the insurance and/or any contractual indemnities of our vendors, contractors, tenants or other contractual parties will be enough to cover all of our defense costs or any resulting liabilities.
Changes in accounting pronouncements could adversely affect our operating results, in addition to the reported financial performance of our tenants. 
Accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. Uncertainties posed by various initiatives of accounting standard-setting by the Financial Accounting Standards Board and the Securities and Exchange Commission, which create and interpret applicable accounting standards for U.S. companies, may change the financial accounting and reporting standards or their interpretation and application of these standards that govern the preparation of our financial statements. Changes include, but are not limited to, changes in revenue recognition, lease accounting and the adoption of accounting standards likely to require the increased use of “fair-value” measures. 
These changes could have a material impact on our reported financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in potentially material restatements of prior period financial statements. Similarly, these changes could have a material impact on our tenants’ reported financial condition or results of operations or could affect our tenants’ preferences regarding leasing real estate. 
Failure to qualify as a REIT would cause BXP to be taxed as a corporation, which would substantially reduce funds available for payment of dividends. 
If BXP fails to qualify as a REIT for federal income tax purposes, it will be taxed as a corporation unless certain relief provisions apply. We believe that BXP is organized and qualified as a REIT and intends to operate in a manner that will allow BXP to continue to qualify as a REIT. However, we cannot assure you that BXP is qualified as such, or that it will remain qualified as such in the future. This is because qualification as a REIT involves the application of highly technical and complex provisions of the Internal Revenue Code as to which there are only limited judicial and administrative interpretations and involves the determination of facts and circumstances not entirely within our control. Future legislation, new regulations, administrative interpretations or court decisions may significantly change the tax laws or the application of the tax laws with respect to qualification as a REIT for federal income tax purposes or the federal income tax consequences of such qualification. 
In addition, we currently hold certain of our properties through subsidiaries that have elected to be taxed as REITs and we may in the future determine that it is in our best interests to hold one or more of our other properties through one or more subsidiaries that elect to be taxed as REITs. If any of these subsidiaries fails to qualify as a REIT for federal income tax purposes, then BXP may also fail to qualify as a REIT for federal income tax purposes. 
If BXP or any of its subsidiaries that are REITs fails to qualify as a REIT then, unless certain relief provisions apply, it will face serious tax consequences that will substantially reduce the funds available for payment of dividends for each of the years involved because: 
BXP would not be allowed a deduction for dividends paid to stockholders in computing its taxable income and would be subject to federal income tax at regular corporate rates;
BXP also could be subject to the federal alternative minimum tax for tax years ending before January 1, 2018 and possibly increased state and local taxes; and
unless BXP is entitled to relief under statutory provisions, BXP could not elect to be subject to tax as a REIT for four taxable years following the year during which it was disqualified.

35


In addition, if BXP fails to qualify as a REIT and the relief provisions do not apply, it will no longer be required to pay dividends. As a result of all these factors, BXP’s failure to qualify as a REIT could impair our ability to raise capital and expand our business, and it would adversely affect the value of BXP’s common stock. If BXP or any of its subsidiaries that are REITs fails to qualify as a REIT but is eligible for certain relief provisions, then it may retain its status as a REIT, but may be required to pay a penalty tax, which could be substantial. 
In order to maintain BXP’s REIT status, we may be forced to borrow funds during unfavorable market conditions. 
In order to maintain BXP’s REIT status, we may need to borrow funds on a short-term basis to meet the REIT distribution requirements, even if the then-prevailing market conditions are not favorable for these borrowings. To qualify as a REIT, BXP generally must distribute to its stockholders at least 90% of its taxable income each year, excluding capital gains and with certain other adjustments. In addition, BXP will be subject to a 4% nondeductible excise tax on the amount, if any, by which dividends paid in any calendar year are less than the sum of 85% of ordinary income, 95% of capital gain net income and 100% of undistributed income from prior years. We may need short-term debt or long-term debt or proceeds from asset sales, creation of joint ventures or sales of common stock to fund required distributions as a result of differences in timing between the actual receipt of income and the recognition of income for federal income tax purposes, or the effect of non-deductible capital expenditures, the creation of reserves or required debt or amortization payments. Any inability of our cash flows to cover our distribution requirements could have an adverse impact on our ability to raise short- and long-term debt or sell equity securities in order to fund distributions required to maintain BXP’s REIT status. 
Limits on changes in control may discourage takeover attempts beneficial to stockholders. 
Provisions in BXP’s charter and bylaws, BXP’s shareholder rights agreement and the limited partnership agreement of BPLP, as well as provisions of the Internal Revenue Code and Delaware corporate law, may: 
delay or prevent a change of control over BXP or a tender offer, even if such action might be beneficial to BXP’s stockholders; and
limit BXP’s stockholders’ opportunity to receive a potential premium for their shares of common stock over then-prevailing market prices.
Stock Ownership Limit 
To facilitate maintenance of BXP’s qualification as a REIT and to otherwise address concerns relating to concentration of stock ownership, BXP’s charter generally prohibits ownership, directly, indirectly or beneficially, by any single stockholder of more than 6.6% of the number of outstanding shares of any class or series of its common stock. We refer to this limitation as the “ownership limit.” BXP’s Board of Directors may waive, in its sole discretion, or modify the ownership limit with respect to one or more persons if it is satisfied that ownership in excess of this limit will not jeopardize BXP’s status as a REIT for federal income tax purposes. In addition, under BXP’s charter, each of Mortimer B. Zuckerman and the respective families and affiliates of Mortimer B. Zuckerman and Edward H. Linde, as well as, in general, pension plans and mutual funds, may actually and beneficially own up to 15% of the number of outstanding shares of any class or series of BXP’s equity common stock. Shares owned in violation of the ownership limit will be subject to the loss of rights to distributions and voting and other penalties. The ownership limit may have the effect of inhibiting or impeding a change in control. 
BPLP’s Partnership Agreement 
BXP has agreed in the limited partnership agreement of BPLP not to engage in specified extraordinary transactions, including, among others, business combinations, unless limited partners of BPLP other than BXP receives, or have the opportunity to receive, either (1) the same consideration for their partnership interests as holders of BXP common stock in the transaction or (2) limited partnership units that, among other things, would entitle the holders, upon redemption of these units, to receive shares of common equity of a publicly traded company or the same consideration as holders of BXP common stock received in the transaction. If these limited partners would not receive such consideration, we cannot engage in the transaction unless limited partners holding at least 75% of the common units of limited partnership interest, other than those held by BXP or its affiliates, consent to the transaction. In addition, BXP has agreed in the limited partnership agreement of BPLP that it will not complete specified extraordinary transactions, including among others, business combinations, in which BXP receive the approval of its common stockholders unless (1) limited partners holding at least 75% of the common units of limited partnership interest, other than those held by BXP or its affiliates, consent to the transaction or (2)

36


the limited partners of BPLP are also allowed to vote and the transaction would have been approved had these limited partners been able to vote as common stockholders on the transaction. Therefore, if BXP’s common stockholders approve a specified extraordinary transaction, the partnership agreement requires the following before it can complete the transaction: 
holders of partnership interests in BPLP, including BXP, must vote on the matter;
BXP must vote its partnership interests in the same proportion as its stockholders voted on the transaction; and
the result of the vote of holders of partnership interests in BPLP must be such that had such vote been a vote of stockholders, the business combination would have been approved.
With respect to specified extraordinary transactions, BXP has agreed in BPLP’s partnership agreement to use its commercially reasonable efforts to structure such a transaction to avoid causing its limited partners to recognize gain for federal income tax purposes by virtue of the occurrence of or their participation in such a transaction.
As a result of these provisions, a potential acquirer may be deterred from making an acquisition proposal, and BXP may be prohibited by contract from engaging in a proposed extraordinary transaction, including a proposed business combination, even though BXP stockholders approve of the transaction. 
Changes in market conditions could adversely affect the market price of BXP’s common stock. 
As with other publicly traded equity securities, the value of BXP’s common stock depends on various market conditions that may change from time to time. Among the market conditions that may affect the value of BXP’s common stock are the following: 
the extent of investor interest in our securities;
the general reputation of REITs and the attractiveness of our equity securities in comparison to other equity securities, including securities issued by other real estate-based companies;
our underlying asset value;
investor confidence in the stock and bond markets, generally;
national economic conditions;
changes in tax laws;
our financial performance;
changes in our credit ratings; and
general stock and bond market conditions, including changes in interest rates.
The market value of BXP’s common stock is based primarily upon the market’s perception of our growth potential and our current and potential future earnings and cash dividends. Consequently, BXP’s common stock may trade at prices that are greater or less than BXP’s net asset value per share of common stock. If our future earnings or cash dividends are less than expected, it is likely that the market price of BXP’s common stock will diminish. 
Further issuances of equity securities may be dilutive to current securityholders. 
The interests of our existing securityholders could be diluted if additional equity securities are issued to finance future developments, acquisitions or repay indebtedness. Our ability to execute our business strategy depends on our access to an appropriate blend of debt financing, including unsecured lines of credit and other forms of secured and unsecured debt, and equity financing, including common and preferred equity.
The number of shares available for future sale could adversely affect the market price of BXP’s stock. 
In connection with and subsequent to BXP’s initial public offering, we have completed many private placement transactions in which shares of stock of BXP or partnership interests in BPLP were issued to owners of properties we acquired or to institutional investors. This common stock, or common stock issuable in exchange for such partnership interests in BPLP, may be sold in the public securities markets over time under registration rights we

37


granted to these investors. Additional common stock issuable under our employee benefit and other incentive plans, including as a result of the grant of stock options and restricted equity securities, may also be sold in the market at some time in the future. Future sales of BXP common stock in the market could adversely affect the price of its common stock. We cannot predict the effect the perception in the market that such sales may occur will have on the market price of BXP’s common stock. 
We may change our policies without obtaining the approval of our stockholders. 
Our operating and financial policies, including our policies with respect to acquisitions of real estate, growth, operations, indebtedness, capitalization and dividends, are exclusively determined by BXP’s Board of Directors. Accordingly, our securityholders do not control these policies.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities
(a) The common stock of Boston Properties, Inc. is listed on the New York Stock Exchange under the symbol “BXP.” At February 21, 2020, BXP had approximately 1,121 stockholders of record. 
There is no established public trading market for BPLP’s common units. On February 21, 2020, there were approximately 313 holders of record and 173,064,320 common units outstanding, 155,121,560 of which were held by BXP.
In order to enable BXP to maintain its qualification as a REIT, it must make annual distributions to its stockholders of at least 90% of its taxable income (not including net capital gains and with certain other adjustments). BXP has adopted a policy of paying regular quarterly dividends on its common stock, and, as BPLP’s general partner, BXP has adopted a policy of paying regular quarterly distributions on common units of BPLP.
Cash distributions have been paid on the common stock of BXP and BPLP’s common units since BXP’s initial public offering. Distributions are declared at the discretion of the Board of Directors of BXP and depend on actual and anticipated cash from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Internal Revenue Code and other factors the Board of Directors of BXP may consider relevant.
Stock Performance Graph 
The following graph provides a comparison of cumulative total stockholder return for the period from December 31, 2014 through December 31, 2019, among BXP, Standard & Poor’s (“S&P”) 500 Index, Nareit Equity REIT Total Return Index (the “Equity REIT Index”) and the Nareit Office REIT Index (the “Office REIT Index”). The Equity REIT Index includes all tax-qualified equity REITs listed on the New York Stock Exchange, the American Stock Exchange and the Nasdaq Stock Market. Equity REITs are defined as those with 75% or more of their gross invested book value of assets invested directly or indirectly in the equity ownership of real estate. The Office REIT Index includes all office REITs included in the Equity REIT Index. Data for BXP, the S&P 500 Index, the Equity REIT Index and the Office REIT Index was provided to us by Nareit. Upon written request, we will provide any stockholder with a list of the REITs included in the Equity REIT Index and the Office REIT Index. The stock performance graph assumes an investment of $100 in each of BXP and the three indices, and the reinvestment of any dividends. The historical information set forth below is not necessarily indicative of future performance. The data shown is based on the share prices or index values, as applicable, at the end of each month shown.

On January 1, 2016, we adopted Accounting Standards Update (“ASU”) 2015-03 and retrospectively applied the guidance to our Mortgage Notes Payable and Unsecured Senior Notes for all periods presented. Unamortized deferred financing costs, with the exception of December 31, 2019, 2018, 2017 and 2016, were previously included in Total Assets totaling approximately $28.0 million are now included in Total Indebtedness as of December 31, 2015.

Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of Nareit, we calculate Funds from Operations, or “FFO,” for BXP by adjusting net income attributable to Boston Properties, Inc. common shareholders (computed in accordance with GAAP) for gains (or losses) from sales of properties, impairment losses on depreciable real estate consolidated on BXP’s balance sheet, impairment losses on our investments in unconsolidated joint ventures driven by a measurable decrease in the fair value of depreciable real estate held by the unconsolidated joint ventures and our share of real estate-related depreciation and amortization. FFO is a non-GAAP financial measure. We believe the presentation of FFO, combined with the presentation of required GAAP financial measures, has improved the understanding of operating results of REITs among the investing public and has helped make comparisons of REIT operating results more meaningful. Management generally considers FFO to be a useful measure for understanding and comparing BXP’s operating results because, by excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment losses and real estate asset depreciation and amortization (which can differ across owners of similar assets in similar condition based on historical cost accounting and useful life estimates), FFO can help investors compare the operating performance of a company’s real estate across reporting periods and to the operating performance of other companies. Amount represents BXP’s share, which was 89.77%, 89.83%, 89.82%, 89.70% and 89.68% for the years ended December 31, 2019, 2018, 2017, 2016 and 2015, respectively, after allocation to the noncontrolling interests.
Our computation of FFO may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current Nareit definition or that interpret the current Nareit definition differently. We believe that in order to facilitate a clear understanding of our operating results, FFO should be examined in conjunction with net income attributable to Boston Properties, Inc. common shareholders as presented in BXP’s Consolidated Financial Statements. FFO should not be considered as a substitute for net income attributable to Boston Properties, Inc. common shareholders (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to BXP’s financial information prepared in accordance with GAAP.  
A reconciliation of FFO attributable to Boston Properties, Inc. common shareholders to net income attributable to Boston Properties, Inc. common shareholders computed in accordance with GAAP is provided under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Funds from Operations.”

On January 1, 2018, we adopted ASU 2016-15 and ASU 2016-18 and retrospectively applied the guidance to our Consolidated Statements of Cash Flows for all periods presented. The adoption of ASU 2016-15 and ASU 2016-18 required us to include Cash Held in Escrows with Cash and Cash Equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the Consolidated Statements of Cash Flows and required us to classify debt prepayment and extinguishment costs as a component of financing activities instead of as a component of operating activities in our Consolidated Statements of Cash Flows resulting in changes to the reported amounts of cash flows provided by (used in) operating, investing and financing activities.

Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report.
Forward-Looking Statements
The Annual Reports on Form 10-K, including the documents incorporated by reference, contain forward-looking statements within the meaning of the federal securities laws, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. We intend these forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and are including this statement for purposes of complying with those safe harbor provisions. Such statements are contained principally, but not only, under the captions “BusinessBusiness and Growth Strategies,” “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” We caution investors that any such forward-looking statements are based on beliefs and on assumptions made by, and information currently available to, our management. When used, the words “anticipate,” “believe,” “budget,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “project,” “should,” “will” and similar expressions which do not relate solely to historical matters are intended to identify forward-looking statements. Such statements are subject to risks, uncertainties and assumptions and are not guarantees of future performance, which may be affected by known and unknown risks, trends, uncertainties and factors that are beyond our control. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected by the forward-looking statements. We caution you that, while forward-looking statements reflect our good-faith beliefs when we make them, they are not guarantees of future performance and are impacted by actual events when they occur after we make such statements. Accordingly, investors should use caution in relying on forward-looking statements, which are based on results and trends at the time they are made, to anticipate future results or trends.
Some of the risks and uncertainties that may cause our actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements include, among others, the following:
if there is a negative change in the economy, including, but not limited to, a reversal of current job growth trends and an increase in unemployment, it could have a negative effect on the following, among other things:
the fundamentals of our business, including overall market occupancy, tenant space utilization and rental rates;
the financial condition of our tenants, many of which are financial, legal, media/telecommunication, technology and other professional firms, our lenders, counterparties to our derivative financial instruments and institutions that hold our cash balances and short-term investments, which may expose us to increased risks of default by these parties; and
the value of our real estate assets, which may limit our ability to dispose of assets at attractive prices or obtain or maintain debt financing secured by our properties or on an unsecured basis;
volatile or adverse global economic and political conditions, health crises and dislocations in the credit markets could adversely affect our access to cost-effective capital and have a resulting material adverse effect on our business opportunities, results of operations and financial condition;
general risks affecting the real estate industry (including, without limitation, the inability to enter into or renew leases, tenant space utilization, dependence on tenants’ financial condition, and competition from other developers, owners and operators of real estate);
failure to manage effectively our growth and expansion into new markets and sub-markets or to integrate acquisitions and developments successfully;
the ability of our joint venture partners to satisfy their obligations;
risks and uncertainties affecting property development and construction (including, without limitation, construction delays, increased construction costs, cost overruns, inability to obtain necessary permits, tenant accounting considerations that may result in negotiated lease provisions that limit a tenant’s liability during construction, and public opposition to such activities);
risks associated with the availability and terms of financing and the use of debt to fund acquisitions and developments or refinance existing indebtedness, including the impact of higher interest rates on the cost and/or availability of financing;

55


risks associated with forward interest rate contracts and the effectiveness of such arrangements;
risks associated with downturns in the national and local economies, increases in interest rates, and volatility in the securities markets;
risks associated with actual or threatened terrorist attacks;
costs of compliance with the Americans with Disabilities Act and other similar laws;
potential liability for uninsured losses and environmental contamination;
risks associated with the physical effects of climate change;
risks associated with security breaches through cyber attacks, cyber intrusions or otherwise, as well as other significant disruptions of our information technology (IT) networks and related systems, which support our operations and our buildings;
risks associated with BXP’s potential failure to qualify as a REIT under the Internal Revenue Code of 1986, as amended;
possible adverse changes in tax and environmental laws;
the impact of newly adopted accounting principles on our accounting policies and on period-to-period comparisons of financial results;
risks associated with possible state and local tax audits; and
risks associated with our dependence on key personnel whose continued service is not guaranteed.
The risks set forth above are not exhaustive. Other sections of this report, including “Part I, Item 1A—Risk Factors,” include additional factors that could adversely affect our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all risk factors, nor can we assess the impact of all risk factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

Overview
BXP is the largest publicly-traded office real estate investment trust (REIT) (based on total market capitalization) as of December 31, 2019 in the United States that develops, owns and manages primarily Class A office properties concentrated in five markets in the United States - Boston, Los Angeles, New York, San Francisco and Washington, DC. BPLP is the entity through which BXP conducts substantially all of its business and owns (either directly or through subsidiaries) substantially all of its assets. We generate revenue and cash primarily by leasing Class A office space to our tenants. When making leasing decisions, we consider, among other things, the creditworthiness of the tenant, the length of the lease, the rental rate to be paid at inception and throughout the lease term, the costs of tenant improvements and other landlord concessions, anticipated operating expenses and real estate taxes, current and anticipated vacancy, current and expected future demand for the space, the impact of any expansion rights and general economic factors.
Our core strategy has always been to develop, acquire and manage high-quality properties in supply-constrained markets with high barriers-to-entry and to focus on executing long-term leases with financially strong tenants. Our tenant base is diverse across market sectors and the weighted-average lease term for our in-place leases was approximately 8.4 years, as of December 31, 2019, including leases signed by our unconsolidated joint ventures. The weighted-average lease term for our top 20 office tenant leases was approximately 11.4 years. Historically, these factors have minimized our exposure in weaker economic cycles and enhanced revenues as market conditions improve. To be successful in any leasing environment, we believe we must consider all aspects of the tenant-landlord relationship. In this regard, we believe that our competitive advantage is based on the following attributes:

56


our understanding of tenants’ short- and long-term space utilization and amenity needs in the local markets;
our reputation as a premier developer, owner and manager of primarily Class A office properties;
our financial strength and our ability to maintain high building standards;
our focus on developing and operating in a sustainable and responsible manner; and
our relationships with local brokers.
Outlook
Macroeconomic conditions remained stable and overall favorable for us in the fourth quarter of 2019. U.S. GDP continues to increase at an estimated annual rate of 2.1% in the fourth quarter and job creation remained steady as the U.S. economy created approximately 593,000 jobs in the fourth quarter of 2019 and the unemployment rate remained low at 3.5%. The 10-year U.S. Treasury rate remains attractive and the Federal Reserve continues to keep the overnight lending rates low and has not indicated any near-term changes.
While political and global risks have tempered, recent events regarding the coronavirus have prompted concerns and its long-term impact on global economics and our business is not yet known. We continue to be optimistic for our industry generally and our company in particular given the positive economic statistics, low interest rates, strong leasing trends in most of our core markets and the continued success of our development efforts. As a leading developer, owner and manager of marquee Class A office properties in the U.S., our priorities remain focused on the following:
ensuring tenant satisfaction;
leasing available space in our in-service and development properties, as well as proactively focusing on future lease expirations;
completing the construction of our development properties;
continuing and completing the redevelopment and repositioning of several key properties to increase future revenue and asset values over the long-term;
maintaining discipline in our underwriting of investment opportunities;
managing our near-term debt maturities and maintaining our conservative balance sheet; and
actively managing our operations in a sustainable and responsible manner.
The overall occupancy of our in-service office and retail properties was 93.0% at December 31, 2019, an increase of 160 basis points year-over-year as compared to December 31, 2018 and an increase of 40 basis points as compared to September 30, 2019. During the fourth quarter of 2019, we signed leases across our portfolio totaling approximately 1.7 million square feet and we commenced revenue recognition on approximately 1.1 million square feet of leases in second generation space. Of these second generation leases, approximately 826,000 square feet had been vacant for less than one year and, in the aggregate, they represent an increase in net rental obligations (gross rent less operating expenses) of approximately 48% over the prior leases.
Our core investment strategy remains unchanged. Other than possible selective acquisitions of “value-add” assets (e.g., assets that require lease-up or repositioning), and acquisitions that are otherwise consistent with our long-term strategy, we intend to continue to focus on investing primarily in higher-yielding new development opportunities. From time to time, due to anticipated market demand, specific tenant considerations and similar factors, we may commence a development project prior to signing leases with tenants.
Consistent with this strategy, in 2019, we completed and fully placed in-service approximately 865,000 net rentable square feet of new development at approximately 98% leased, including leases with future commencement dates. During the fourth quarter of 2019, we fully placed in-service The Hub on Causeway - Podium, an approximately 382,000 net rentable square foot property containing retail and office space located in Boston, Massachusetts. The property is 99% leased, including leases with future commencement dates. The Hub on Causeway - Podium is part of a 1.3 million square foot mixed-use development project adjacent to the North Station transit center. We have a 50% ownership interest in the development. We also placed in service 145

57


Broadway, an approximately 483,000 net rentable square foot property located in Cambridge, Massachusetts. The property is 98% leased to a single tenant.
As of December 31, 2019, our construction/redevelopment pipeline consisted of 11 properties that, when completed, we expect will total approximately 5.5 million net rentable square feet. Our share of the estimated total cost for these projects is approximately $3.1 billion, of which approximately $1.4 billion remains to be invested as of December 31, 2019. Approximately 76% of the commercial space in these development projects was pre-leased as of February 21, 2020.
As we continue to focus on the development and acquisition of assets to enhance our long-term growth, we also continually review our portfolio to identify properties as potential sales candidates that either no longer fit within our portfolio strategy or could attract premium pricing in the current market environment. For example, during the fourth quarter of 2019, we entered into an agreement for the sale of our New Dominion Technology Park located in Herndon, Virginia for a gross sale price of $256.0 million. The sale was completed on February 20, 2020. New Dominion Technology Park consists of two Class A office properties aggregating approximately 493,000 net rentable square feet. In 2019, we disposed of approximately $406 million of assets. We expect to continue to sell select assets as we move through 2020, subject to market conditions.
A brief overview of each of our markets follows.
Boston
The leasing market in the greater Boston region remains active and strong. Demand in the Boston central business district (“CBD”) continues to be driven by a strong flow of new and expanding technology and life science companies, traditional financial and professional services tenants and the ongoing trend of urbanization. During the fourth quarter of 2019, we executed approximately 317,000 square feet of leases and had approximately 1.0 million square feet of leases commence in the Boston region. Approximately 356,000 square feet of the leases that commenced had been vacant for less than one year and represent an increase in net rental obligations of approximately 79% over the prior leases. We are also actively working to meet tenant demand in Boston through new development. In addition to fully placing in-service The Hub on Causeway - Podium and partially placing in-service the Hub50House in the fourth quarter of 2019, we continued development of 100 Causeway Street, a 632,000 net rentable square foot office tower located in Boston, Massachusetts, of which we own 50%, that is 94% pre-leased, as of February 21, 2020, and is expected to be delivered in 2021.
Our approximately 2.0 million square foot in-service office portfolio in Cambridge is 99% leased, as of December 31, 2019, dominated by large users and continues to generate strong rental rates. On October 24, 2019, we completed and placed in-service 145 Broadway, an approximately 483,000 net rentable square foot office property that is 98% leased. We also continued the development of 325 Main Street at Kendall Center in Cambridge, Massachusetts, which is 90% pre-leased to a tenant for a term of 15 years.
In the suburban Waltham/Lexington sub-market, we continue to experience significant demand within our existing tenant base and from other tenants in the market, particularly from technology and life science companies seeking space to accommodate their expanding workforces. To capitalize on this demand, we commenced the redevelopment of a portion of 200 West Street, an approximately 261,000 net rentable square foot Class A office property in Waltham, Massachusetts. The redevelopment is a conversion of a portion of the property to laboratory space to meet growing demand in the life sciences sector.
The primary challenge we have in our Boston portfolio is the lack of available space to meet tenant demand. As a result, we are focused on future lease expirations and are working on expansions and early renewals that are expected to result in increases in future rents. We are also actively marketing new development sites in Boston and Waltham. The Boston, Cambridge and the suburban Waltham/Lexington sub-market have continued to experience strong increases in rental rates.
Los Angeles
The market in Los Angeles (“LA”) remains strong, particularly in West LA where our Colorado Center complex, of which we own 50%, and our 21-building Santa Monica Business Park, of which we own 55%, are located. We believe both properties provide us with ample opportunity for future growth, as a majority of the current leases are at below-market rents. As of December 31, 2019, our LA in-service properties are approximately 97% leased. We have the opportunity to increase revenue through completing renewals at higher rents on most of the approximately

58


707,000 square feet of office leases that will expire at the end of 2020 through 2021. We will continue to explore opportunities to increase our presence in the LA market by seeking investments where our financial, operational, redevelopment and development expertise provide the opportunity to achieve accretive returns.
New York
As of December 31, 2019, our New York CBD in-service portfolio was approximately 94% leased. In the fourth quarter of 2019, we commenced approximately 537,000 square feet of leases in the New York region. Of these leases, approximately 271,000 square feet had been vacant for less than one year and represent an increase in net rental obligations of approximately 17% over the prior leases.
Although overall leasing activity remains strong due to ongoing demand for new or recently renovated high-quality office space, particularly in midtown Manhattan, rental rate growth in New York City remains muted due to increased supply. During 2019, we increased the occupancy in our New York City portfolio by 2.6% to 94.4% at December 31, 2019. As a result, we continue to expect stable rent and tenant improvement allowances in our New York submarkets.
San Francisco
Our San Francisco CBD in-service properties are approximately 97% leased as of December 31, 2019. During the fourth quarter of 2019, we commenced approximately 241,000 square feet of leases in the San Francisco region. Of these leases, approximately 167,000 square feet had been vacant for less than one year and represent an increase in net rental obligations of approximately 57% over the prior leases. The San Francisco market conditions remain favorable with market vacancy rates in the low single digits. During the fourth quarter of 2019, we secured approval from the City of San Francisco Planning Commission for our 425 Fourth Street development project located in San Francisco’s Central SoMa District. The approval includes the Large Project Authorization for the design and massing of an approximately 820,000 square foot project, as well as an initial allocation of 505,000 square feet under the San Francisco Office Development Annual Limitation Program (Prop M) for the first phase of the project.
San Francisco CBD continues to experience strong employment trends and limited supply of Class A office space. As market demand from technology and life sciences companies continues to grow, companies often seek locations in close proximity to the San Francisco CBD that offer access to public transportation and more efficient commutes for their employees. To meet this demand, we have several large scale development opportunities in Silicon Valley that we are marketing to tenants, including Platform 16, an approximately 1.1 million square foot Class A urban office campus located on a 5.6-acre site in downtown San Jose, California in which we have a 55% interest.  On January 28, 2020, the joint venture commenced development of the first phase of Platform 16, which will consist of an approximately 390,000 net rentable square foot Class A office building and a below grade parking garage. Platform 16 is adjacent to Google’s planned multimillion square foot transit village and Diridon Station, the largest multi-modal transportation hub in the Bay Area consisting of Caltrain, VTA light-rail, the ACE train and the planned BART and high-speed rail lines. 
On January 28, 2020, we entered into a joint venture with Alexandria Real Estate Equities to own, operate and develop approximately 1.1 million square feet of existing office and lab properties in South San Francisco, California, with the opportunity for approximately 640,000 square feet of additional future development.  Upon completion, the joint venture is expected to own an approximately 1.7 million square foot life sciences campus, including a mix of office and lab buildings.  Under the joint venture agreement, we contributed 601, 611 and 651 Gateway Boulevard, three existing office properties that total approximately 768,000 net rentable square feet, and developable land.  Alexandria Real Estate Equities contributed approximately 313,000 square feet of existing properties including lab, office and amenity buildings, and developable land.  We have a 50% ownership interest in the joint venture (See Note 19 to the Consolidated Financial Statements). The South San Francisco market has experienced strong demand from companies in the life sciences sector. We expect this joint venture will allow us to expand the amount of developable land on the combined site and efficiently capitalize on tenant demand in the life sciences sector.
Washington, DC
Market conditions in the Washington, DC CBD have not changed in any meaningful way over the past few quarters. In the Washington, DC region, our focus remains on (1) expanding our development potential in Reston, Virginia, where demand from technology and cybersecurity tenants remains strong, (2) divesting of assets in

59


Washington, DC and select suburban markets and (3) matching development sites with tenants to begin development with significant pre-leasing commitments.
In our Reston, Virginia portfolio, we continued development of Reston Gateway, our mixed-use development project, which will consist of an aggregate of approximately 4.5 million net rentable square feet. The initial phase is approximately 1.1 million net rentable square feet, of which approximately 80% is pre-leased to Fannie Mae. Our Reston, Virginia in-service portfolio was approximately 93% leased as of December 31, 2019 and continues to be the strongest submarket in the region.
Conversely, leasing activity in the Washington, DC CBD remains very competitive primarily because there has been an increase in supply without a corresponding increase in demand. We are reasonably well-leased in the CBD with modest near-term exposure and we have reduced our exposure in the Washington, DC CBD market significantly over the past few years through dispositions of assets.

For descriptions of significant transactions that we completed during 2019, see “Item 1. Business—Transactions During 2019.”
Critical Accounting Policies
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to use judgment in the application of accounting policies, including making estimates and assumptions. We base our estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. These judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. If our judgment or interpretation of the facts and circumstances relating to various transactions had been different, it is possible that different accounting policies would have been applied resulting in a different presentation of our financial statements. From time to time, we evaluate our estimates and assumptions. In the event estimates or assumptions prove to be different from actual results, adjustments are made in subsequent periods to reflect more current information. Below is a discussion of accounting policies that we consider critical in that they may require complex judgment in their application or require estimates about matters that are inherently uncertain.
Real Estate
Upon acquisitions of real estate, we assess whether the transaction should be accounted for as an asset acquisition or as a business combination by applying a screen to determine whether the integrated set of assets and activities acquired meets the definition of a business. Acquisitions of integrated sets of assets and activities that do not meet the definition of a business are accounted for as asset acquisitions. Our acquisitions of real estate or in-substance real estate generally will not meet the definition of a business because substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets (i.e. land, buildings, and related intangible assets) or because the acquisition does not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort or delay.
We assess the fair value of acquired tangible and intangible assets (including land, buildings, tenant improvements, “above-” and “below-market” leases, leasing and assumed financing origination costs, acquired in-place leases, other identified intangible assets and assumed liabilities) and allocate the purchase price to the acquired assets and assumed liabilities, including land and buildings as if vacant. We assess fair value based on estimated cash flow projections that utilize discount and/or capitalization rates that we deem appropriate, as well as available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known and anticipated trends, and market and economic conditions.
The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. We also consider an allocation of purchase price of other acquired intangibles, including acquired in-place leases that may have a customer relationship intangible value, including (but not limited to) the nature and extent of the existing relationship with the tenants, the tenants’ credit quality and expectations of lease renewals. Based on our acquisitions to date, our allocation to customer relationship intangible assets has been immaterial.

61


We record acquired “above-” and “below-market” leases at their fair values (using a discount rate which reflects the risks associated with the leases acquired) equal to the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) management’s estimate of fair market lease rates for each corresponding in-place lease, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the term of any below-market fixed rate renewal options for below-market leases. Acquired “above-” and “below-market” lease values have been reflected within Prepaid Expenses and Other Assets and Other Liabilities, respectively, in our Consolidated Balance Sheets. Other intangible assets acquired include amounts for in-place lease values that are based on our evaluation of the specific characteristics of each tenant’s lease. Factors to be considered include estimates of carrying costs during hypothetical expected lease-up periods considering current market conditions, and costs to execute similar leases. In estimating carrying costs, we include real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, we consider leasing commissions, legal and other related expenses.
Management reviews its long-lived assets for impairment following the end of each quarter and when there is an event or change in circumstances that indicates carrying amounts may not be recoverable. An impairment loss is recognized if the carrying amount of an asset is not recoverable and exceeds its fair value. The evaluation of anticipated cash flows is subjective and is based in part on assumptions regarding anticipated hold periods, future occupancy, future rental rates, future capital requirements, discount rates and capitalization rates that could differ materially from actual results in future periods. Because cash flows on properties considered to be “long-lived assets to be held and used” are considered on an undiscounted basis to determine whether an asset has been impaired, our established strategy of holding properties over the long term directly decreases the likelihood of recording an impairment loss. If our hold strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized and such loss could be material. If we determine that an impairment has occurred, the affected assets must be reduced to their fair value.
Guidance in Accounting Standards Codification (“ASC”) 360 “Property Plant and Equipment” (“ASC 360”) requires that qualifying assets and liabilities and the results of operations that have been sold, or otherwise qualify as “held for sale,” be presented as discontinued operations in all periods presented if the property operations are expected to be eliminated and we will not have significant continuing involvement following the sale. Discontinued operations presentation applies only to disposals representing a strategic shift that has (or will have) a major effect on an entity’s operations and financial results (e.g., a disposal of a major geographical area, a major line of business, a major equity method investment or other major parts of an entity). The components of the property’s net income that are reflected as discontinued operations include the net gain (or loss) upon the disposition of the property held for sale, operating results, depreciation and interest expense (if the property is subject to a secured loan). We generally consider assets to be “held for sale” when the transaction has been approved by BXP’s Board of Directors, or a committee thereof, and there are no known significant contingencies relating to the sale, such that a sale of the property within one year is considered probable. Following the classification of a property as “held for sale,” no further depreciation is recorded on the assets, and the asset is written down to the lower of carrying value or fair market value, less cost to sell.
Real estate is stated at depreciated cost. A variety of costs are incurred in the acquisition, development and leasing of properties. The cost of buildings and improvements includes the purchase price of property, legal fees and other acquisition costs. We capitalize acquisition costs that we incur to effect an asset acquisition and expense acquisition costs that we incur to effect a business combination, including legal, due diligence and other closing related costs. Costs directly related to the development of properties are capitalized. Capitalized development costs include interest, internal wages, property taxes, insurance, and other project costs incurred during the period of development. After the determination is made to capitalize a cost, it is allocated to the specific component of the project that benefited from the investment. Determination of when a development project commences and capitalization begins, and when a development project is substantially complete and held available for occupancy and capitalization must cease, involves a degree of judgment. Our capitalization policy on development properties follows the guidance in ASC 835-20 “Capitalization of Interest” and ASC 970 “Real Estate-General.” The costs of land and buildings under development include specifically identifiable costs.
Capitalized costs include pre-construction costs necessary to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. We begin the capitalization of costs during the pre-construction period, which we define as activities that are necessary for the development of the property. We consider a construction project as substantially complete and held available for occupancy upon the completion of tenant improvements, but no later than one year from cessation of major construction activity. We cease capitalization on the portion (1) substantially

62


completed, (2) occupied or held available for occupancy, and capitalize only those costs associated with the portion under construction or (3) if activities necessary for the development of the property have been suspended.
Investments in Unconsolidated Joint Ventures
We consolidate variable interest entities (“VIEs”) in which we are considered to be the primary beneficiary. VIEs are entities in which the equity investors do not have sufficient equity at risk to finance their endeavors without additional financial support or that the holders of the equity investment at risk do not have substantive participating rights. The primary beneficiary is defined by the entity having both of the following characteristics: (1) the power to direct the activities that, when taken together, most significantly impact the variable interest entity’s performance, and (2) the obligation to absorb losses and the right to receive the returns from the variable interest entity that could potentially be significant to the VIE. For ventures that are not VIEs, we consolidate entities for which we have significant decision making control over the ventures’ operations. Our judgment with respect to our level of influence or control of an entity involves the consideration of various factors including the form of our ownership interest, our representation in the entity’s governance, the size of our investment (including loans), estimates of future cash flows, our ability to participate in policy making decisions and the rights of the other investors to participate in the decision making process and to replace us as manager and/or liquidate the venture, if applicable. Our assessment of our influence or control over an entity affects the presentation of these investments in our consolidated financial statements. In addition to evaluating control rights, we consolidate entities in which the outside partner has no substantive kick-out rights to remove us as the managing member.
Accounts of the consolidated entity are included in our accounts and the noncontrolling interest is reflected on the Consolidated Balance Sheets as a component of equity or in temporary equity between liabilities and equity. Investments in unconsolidated joint ventures are recorded initially at cost, and subsequently adjusted for equity in earnings and cash contributions and distributions. Any difference between the carrying amount of these investments on the balance sheet and the underlying equity in net assets is amortized as an adjustment to equity in earnings of unconsolidated joint ventures over the life of the related asset. Under the equity method of accounting, our net equity investment is reflected within the Consolidated Balance Sheets, and our share of net income or loss from the joint ventures is included within the Consolidated Statements of Operations. The joint venture agreements may designate different percentage allocations among investors for profits and losses; however, our recognition of joint venture income or loss generally follows the joint venture’s distribution priorities, which may change upon the achievement of certain investment return thresholds. We may account for cash distributions in excess of our investment in an unconsolidated joint venture as income when we are not the general partner in a limited partnership and when we have neither the requirement nor the intent to provide financial support to the joint venture. We classify distributions received from equity method investees within our Consolidated Statements of Cash Flows using the nature of the distribution approach, which classifies the distributions received on the basis of the nature of the activity or activities of the investee that generated the distribution as either a return on investment (classified as cash inflows from operating activities) or a return of investment (classified as cash inflows from investing activities). Our investments in unconsolidated joint ventures are reviewed for impairment periodically and we record impairment charges when events or circumstances change indicating that a decline in the fair values below the carrying amounts has occurred and such decline is other-than-temporary. The evaluation of fair value is subjective and is based in part on assumptions regarding future occupancy, future rental rates, future capital requirements, discount rates and capitalization rates that could differ materially from actual results in future periods. The ultimate realization of the investment in unconsolidated joint ventures is dependent on a number of factors, including the performance of each investment and market conditions. We will record an impairment charge if we determine that a decline in the fair value below the carrying amount of an investment in an unconsolidated joint venture is other-than-temporary. 
To the extent that we contribute assets to a joint venture, our investment in the joint venture is recorded at our cost basis in the assets that were contributed to the joint venture. To the extent that our cost basis is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related asset and included in our share of equity in net income of the joint venture. In accordance with the provisions of ASC 610-20 “Gains and Losses from the Derecognition of Nonfinancial Assets” (“ASC 610-20”), we will recognize a full gain on both the retained and sold portions of real estate contributed or sold to a joint venture by recognizing our new equity method investment interest at fair value.
The combined summarized financial information of the unconsolidated joint ventures is disclosed in Note 5 to the Consolidated Financial Statements.

Revenue Recognition
In general, we commence lease/rental revenue recognition when the tenant takes possession of the leased space and the leased space is substantially ready for its intended use. Contractual lease/rental revenue is reported on a straight-line basis over the terms of the respective leases. We recognize acquired in-place “above-” and “below-market” leases at their fair values as lease/rental revenue over the original term of the respective leases. Accrued rental income as reported on the Consolidated Balance Sheets represents cumulative lease/rental income earned in excess of rent payments received pursuant to the terms of the individual lease agreements.
For the year ended December 31, 2019, the impact of the net adjustments of rents from “above-” and “below-market” leases increased lease revenue by approximately $20.9 million. For the year ended December 31, 2019, the impact of the straight-line rent adjustment increased lease revenue by approximately $58.4 million. Those amounts exclude the adjustment of rents from “above-” and “below-market” leases and straight-line income from unconsolidated joint ventures, which are disclosed in Note 5 to the Consolidated Financial Statements.
Our leasing strategy is generally to secure creditworthy tenants that meet our underwriting guidelines. Furthermore, following the initiation of a lease, we continue to actively monitor the tenant’s creditworthiness to ensure that all tenant related assets are recorded at their realizable value. When assessing tenant credit quality, we:
review relevant financial information, including:
financial ratios;
net worth;
revenue;
cash flows;
leverage; and
liquidity;
evaluate the depth and experience of the tenant’s management team; and
assess the strength/growth of the tenant’s industry.
As a result of the underwriting process, tenants are then categorized into one of three categories:
(1)
acceptable-risk tenants;
(2)
the tenant’s credit is such that we may require collateral, in which case we:
may require a security deposit; and/or
may reduce upfront tenant improvement investments; or
(3)
the tenant’s credit is below our acceptable parameters.
We review our trade accounts receivable, including our straight-line rent receivable, related to base rents, straight-line rent, expense reimbursements and other revenues for collectability. We analyze our accounts receivable, customer creditworthiness and current economic trends when evaluating the adequacy of the collectability of the lessee’s total accounts receivable balance on a lease-by-lease basis. In addition, tenants in bankruptcy are analyzed and considerations are made in connection with the expected recovery of pre-petition and post-petition claims. If a lessee’s accounts receivable balance is considered uncollectible, we will write-off the receivable balances associated with the lease to Lease revenue and cease to recognize lease income, including straight-line rent, unless cash is received. If we subsequently determine that it is probable we will collect substantially all the remaining lessee’s lease payments under the lease term, we will then reinstate the straight-line balance, adjusting for the amount related to the period when the lease payments were considered not probable. Our reported net earnings are directly affected by management’s estimate of the collectability of its trade accounts receivable.
The average remaining term of our in-place tenant leases, including unconsolidated joint ventures, was approximately 8.4 years as of December 31, 2019. The credit risk is mitigated by the high quality of our existing tenant base, reviews of prospective tenants’ risk profiles prior to lease execution and consistent monitoring of our portfolio to identify potential problem tenants.
Recoveries from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs, are recognized as revenue in the period during which the expenses are incurred (See “New Accounting Pronouncements Adopted—Leases” within Note 2 to the Consolidated Financial

64


Statements). We recognize these reimbursements on a gross basis, as we obtain control of the goods and services before they are transferred to the tenant. We also receive reimbursements of payroll and payroll related costs from unconsolidated joint venture entities and third party property owners in connection with management services contracts which we reflect on a gross basis instead of on a net basis as we have determined that we are the principal and not the agent under these arrangements in accordance with guidance in ASC 606 “Revenue from Contracts with Customers” (“ASC 606”).
Our parking revenue is derived primarily from monthly and transient daily parking. In addition, we have certain lease arrangements for parking accounted for under the guidance in ASC 842 “Leases” (“ASC 842”). The monthly and transient daily parking revenue falls within the scope of ASC 606 and is accounted for at the point in time when control of the goods or services transfers to the customer and our performance obligation is satisfied.
Our hotel revenue is derived from room rentals and other sources such as charges to guests for telephone service, movie and vending commissions, meeting and banquet room revenue and laundry services. Hotel revenue is recognized as the hotel rooms are occupied and the services are rendered to the hotel customers.
We earn management and development fees. Development and management services revenue is earned from unconsolidated joint venture entities and third-party property owners. We determined that the performance obligations associated with our development services contracts are satisfied over time and that we would recognize our development services revenue under the output method evenly over time from the development commencement date through the substantial completion date of the development management services project due to the stand-ready nature of the contracts. Significant judgments impacting the amount and timing of revenue recognized from our development services contracts include estimates of total development project costs from which the fees are typically derived and estimates of the period of time until substantial completion of the development project, the period of time over which the development services are required to be performed. We recognize development fees earned from unconsolidated joint venture projects equal to its cost plus profit to the extent of the third party partners’ ownership interest. Property management fees are recorded and earned based on a percentage of collected rents at the properties under management, and not on a straight-line basis, because such fees are contingent upon the collection of rents.
Gains on sales of real estate are recognized pursuant to the provisions included in ASC 610-20. Under ASC 610-20, we must first determine whether the transaction is a sale to a customer or non-customer. We typically sell real estate on a selective basis and not within the ordinary course of our business and therefore expects that our sale transactions will not be contracts with customers. We next determine whether we have a controlling financial interest in the property after the sale, consistent with the consolidation model in ASC 810 “Consolidation” (“ASC 810”). If we determine that we do not have a controlling financial interest in the real estate, we evaluate whether a contract exists under ASC 606 and whether the buyer has obtained control of the asset that was sold. We recognize a full gain on sale of real estate when the derecognition criteria under ASC 610-20 have been met.
Depreciation and Amortization
We compute depreciation and amortization on our properties using the straight-line method based on estimated useful asset lives. We allocate the acquisition cost of real estate to its components and depreciate or amortize these assets (or liabilities) over their useful lives. The amortization of acquired “above-” and “below-market” leases and acquired in-place leases is recorded as an adjustment to revenue and depreciation and amortization, respectively, in the Consolidated Statements of Operations.
Fair Value of Financial Instruments
The carrying values of cash and cash equivalents, marketable securities, escrows, receivables, accounts payable, accrued expenses and other assets and liabilities are reasonable estimates of their fair values because of the short maturities of these instruments.
We follow the authoritative guidance for fair value measurements when valuing our financial instruments for disclosure purposes. BPLP determines the fair value of its unsecured senior notes using market prices. The inputs used in determining the fair value of BPLP’s unsecured senior notes are categorized at a Level 1 basis (as defined in ASC 820 “Fair Value Measurements and Disclosures” (“ASC 820”)) due to the fact that it uses quoted market rates to value these instruments. However, the inputs used in determining the fair value could be categorized at a Level 2 basis (as defined in ASC 820) if trading volumes are low. We determine the fair value of our related party note receivable, note receivable and mortgage notes payable using discounted cash flow analysis by discounting the spread between the future contractual interest payments and hypothetical future interest payments on note

65


receivables / mortgage debt based on current market rates for similar securities. In determining the current market rates, we add our estimates of market spreads to the quoted yields on federal government treasury securities with similar maturity dates to our debt. The inputs used in determining the fair value of our related party note receivable, note receivable, and mortgage notes payable are categorized at a Level 3 basis (as defined in ASC 820) due to the fact that we consider the rates used in the valuation techniques to be unobservable inputs. To the extent that there are outstanding borrowings under the unsecured line of credit or unsecured term loan, we utilize a discounted cash flow methodology in order to estimate the fair value. To the extent that credit spreads have changed since the origination, the net present value of the difference between future contractual interest payments and future interest payments based on our estimate of a current market rate would represent the difference between the book value and the fair value. Our estimate of a current market rate is based upon the rate, considering current market conditions and BPLP’s specific credit profile, at which we estimate we could obtain similar borrowings. To the extent there are outstanding borrowings, this current market rate is estimated and therefore would be primarily based upon a Level 3 input (See “New Accounting Pronouncements Issued But Not Yet Adopted—Fair Value Measurement” within Note 2 to the Consolidated Financial Statements”).
Derivative Instruments and Hedging Activities
Derivative instruments and hedging activities require management to make judgments on the nature of its derivatives and their effectiveness as hedges. These judgments determine if the changes in fair value of the derivative instruments are reported in the Consolidated Statements of Operations as a component of net income or as a component of comprehensive income and as a component of equity on the Consolidated Balance Sheets. While management believes its judgments are reasonable, a change in a derivative’s effectiveness as a hedge could materially affect expenses, net income and equity. We account for both the effective and ineffective portions of changes in the fair value of a derivative in other comprehensive income (loss) and subsequently reclassify the fair value of the derivative to earnings over the term that the hedged transaction affects earnings and in the same line item as the hedged transaction within the statements of operations
Income Taxes 
Boston Properties Inc.
BXP has elected to be treated as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), commencing with its taxable year ended December 31, 1997. As a result, it generally will not be subject to federal corporate income tax on its taxable income that is distributed to its stockholders. A REIT is subject to a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its annual taxable income (with certain adjustments). BXP’s policy is to distribute at least 100% of its taxable income. Accordingly, the only provision for federal income taxes in the accompanying consolidated financial statements relates to BXP’s consolidated taxable REIT subsidiaries. BXP’s taxable REIT subsidiaries did not have significant tax provisions or deferred income tax items. BXP has no uncertain tax positions recognized as of December 31, 2019 and 2018. 
We own a hotel property that we lease to one of our taxable REIT subsidiaries and that is managed by Marriott International, Inc. The hotel taxable REIT subsidiary, a wholly owned subsidiary of BPLP, is the lessee pursuant to the lease for the hotel property. As lessor, BPLP is entitled to a percentage of gross receipts from the hotel property. Marriott International, Inc. continues to manage the hotel property under the Marriott name and under terms of a management agreement. The hotel taxable REIT subsidiary is subject to tax at the federal and state level and, accordingly, BXP has recorded a tax provision in its Consolidated Statements of Operations for the years ended December 31, 2019, 2018 and 2017. 
The net difference between the tax basis and the reported amounts of BXP’s assets and liabilities was approximately $1.7 billion and $1.9 billion as of December 31, 2019 and 2018, respectively, which was primarily related to the difference in basis of contributed property and accrued rental income.
Certain entities included in BXP’s Consolidated Financial Statements are subject to certain state and local taxes. These taxes are recorded as operating expenses in the accompanying consolidated financial statements.

At December 31, 2019 and 2018, we owned or had interests in a portfolio of 196 and 197 commercial real estate properties, respectively (in each case, the “Total Property Portfolio”). As a result of changes within our Total Property Portfolio, the financial data presented below shows significant changes in revenue and expenses from period-to-period. Accordingly, we do not believe that our period-to-period financial data with respect to the Total Property Portfolio are necessarily meaningful. Therefore, the comparison of operating results for the years ended December 31, 2019 and 2018 show separately the changes attributable to the properties that were owned by us and in-service throughout each period compared (the “Same Property Portfolio”) and the changes attributable to the properties included in the Placed In-Service, Acquired, Development or Redevelopment or Sold Portfolios.
In our analysis of operating results, particularly to make comparisons of net operating income between periods meaningful, it is important to provide information for properties that were in-service and owned by us throughout each period presented. We refer to properties acquired or placed in-service prior to the beginning of the earliest period presented and owned by us and in-service through the end of the latest period presented as our Same Property Portfolio. The Same Property Portfolio therefore excludes properties placed in-service, acquired or in development or redevelopment after the beginning of the earliest period presented or disposed of prior to the end of the latest period presented.

Net operating income (“NOI”) is a non-GAAP financial measure equal to net income attributable to Boston Properties, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership common unitholders, as applicable, the most directly comparable GAAP financial measures, plus (1) preferred dividends/distributions, net income attributable to noncontrolling interests, interest expense, losses from early extinguishments of debt, impairment losses, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts and corporate general and administrative expense less (2) gains (losses) from investments in securities, interest and other income, gains on sales of real estate, income from unconsolidated joint ventures, direct reimbursements of payroll and related costs from management services contracts and development and management services revenue. We use NOI internally as a performance measure and believe it provides useful information to investors regarding our results of operations and financial condition because, when compared across periods, it reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspective not immediately apparent from net income attributable to Boston Properties, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership common unitholders. For example, interest expense is not necessarily linked to the operating performance of a real estate asset and is often incurred at the corporate level as opposed to the property level. Similarly, interest expense may be incurred at the property level even though the financing proceeds may be used at the corporate level (e.g., used for other investment activity). In addition, depreciation and amortization expense, because of historical cost accounting and useful life estimates, may distort operating performance measures at the property level. NOI presented by us may not be comparable to NOI reported by other REITs or real estate companies that define NOI differently.
We believe that, in order to facilitate a clear understanding of our operating results, NOI should be examined in conjunction with net income attributable to Boston Properties, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership common unitholders as presented in our Consolidated Financial Statements. NOI should not be considered as a substitute for net income attributable to Boston Properties, Inc. common shareholders or net income attributable to Boston Properties Limited Partnership common unitholders (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to our financial information prepared in accordance with GAAP.
The gains on sales of real estate, depreciation expense and impairment losses may differ between BXP and BPLP as a result of previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor OP Unit redemptions by BPLP. This accounting resulted in a step-up of the real estate assets at BXP that was allocated to certain properties. The difference between the real estate assets of BXP as compared to BPLP for certain properties having an allocation of the real estate step-up will result in a corresponding difference in the gains on sales of real estate and depreciation expense when those properties are sold. For additional information see the Explanatory Note that follows the cover page of this Annual Report on Form 10-K.
Comparison of the year ended December 31, 2019 to the year ended December 31, 2018

_______________
(1)
Rental Revenue is equal to Revenue less Development and Management Services Revenue and Direct Reimbursements of Payroll and Related Costs from Management Services Revenue per the Consolidated Statements of Operations, excluding the residential and hotel revenue that is noted below. Upon the adoption of ASU-2016-02 “Leases” on January 1, 2019, service income from tenants is included in Lease revenue. Prior to adoption, these amounts were included in the line item for Development and Management Services Revenue. We use Rental Revenue internally as a performance measure and in calculating other non-GAAP financial measures (e.g., NOI), which provides investors with information regarding our performance that is not immediately apparent from the comparable non-GAAP measures and allows investors to compare operating performance between periods.
(2)
For a detailed discussion of NOI, including the reasons management believes NOI is useful to investors, see page 71. Residential Net Operating Income for the year ended December 31, 2019 and 2018 are comprised of Residential Revenue of $36,914 and $22,551 less Residential Expenses of $15,985 and $12,604, respectively. Hotel Net Operating Income for the year ended December 31, 2019 and 2018 are comprised of Hotel Revenue of $48,589 and $49,118 less Hotel Expenses of $34,004 and $33,863, respectively, per the Consolidated Statements of Operations.

Same Property Portfolio
Lease Revenue (Excluding Termination Income)
Lease revenue from the Same Property Portfolio increased by approximately $146.6 million for the year ended December 31, 2019 compared to 2018. The increase was primarily the result of an increase in revenue from our leases and the reclassification of service income from tenants and other income of approximately $127.1 million and $19.5 million, respectively. Lease revenue from our leases increased by approximately $127.1 million as a result of our average revenue per square foot increasing by approximately $2.85, contributing approximately $94.3 million, and an approximately $32.8 million increase due to our average occupancy increasing from 92.6% to 93.9%.
On January 1, 2019, we adopted ASU 2016-02. As a result of the adoption, there were certain nonlease components (service income from tenants, overtime HVAC, late fees and other items) that were reclassified on a prospective basis from the development and management services revenue and parking and other income line items of our Consolidated Statements of Operations. As a result, lease revenue increased by approximately $19.5 million and development and management services revenue and parking and other income decreased by approximately $12.3 million and $7.2 million, respectively, for the year ended December 31, 2019 (See Note 2 to the Consolidated Financial Statements).
Termination Income
Termination income increased by approximately $9.2 million for the year ended December 31, 2019 compared to 2018.
Termination income for the year ended December 31, 2019 related to 42 tenants across the Same Property Portfolio and totaled approximately $15.4 million, of which approximately $8.2 million is from two tenants that terminated leases early at 399 Park Avenue in New York City.
Termination income for the year ended December 31, 2018 resulted from the termination of 32 tenants across the Same Property Portfolio and totaled approximately $6.2 million, of which approximately $4.8 million was attributable to the New York Region. In addition, we received the sixth interim distribution from our unsecured creditor’s claim against Lehman Brothers, Inc. of approximately $0.3 million (See Note 9 to the Consolidated Financial Statements).
Parking and Other
Parking and other decreased by approximately $3.0 million for the year ended December 31, 2019 compared to 2018, which was primarily due to the reclassification of approximately $7.2 million of certain nonlease components resulting from the adoption of ASU 2016-02, described above (See Note 2 to the Consolidated Financial Statements). Excluding this reclassification, parking and other increased by approximately $4.2 million.
Real Estate Operating Expenses
Real estate operating expenses from the Same Property Portfolio increased by approximately $40.7 million, or 4.4%, for the year ended December 31, 2019 compared to 2018, due primarily to increases in real estate taxes and other real estate operating expenses of approximately $31.2 million, or 6.8%, and $9.5 million, or 2.0%, respectively. The increase in real estate taxes was primarily experienced in the New York CBD properties.
Properties Acquired Portfolio
The table below lists the properties acquired between January 1, 2018 and December 31, 2019. Rental revenue and real estate operating expenses increased by approximately $4.9 million and $2.0 million, respectively, for the year ended December 31, 2019 compared to 2018, as detailed below.

Average Physical Occupancy is defined as (1) the average number of occupied units divided by (2) the total number of units, expressed as a percentage.
(3)
Average Economic Occupancy is defined as (1) total possible revenue less vacancy loss divided by (2) total possible revenue, expressed as a percentage. Total possible revenue is determined by valuing average occupied units at contract rates and average vacant units at Market Rents. Vacancy loss is determined by valuing vacant units at current Market Rents. By measuring vacant units at their Market Rents, Average Economic Occupancy takes into account the fact that units of different sizes and locations within a residential property have different economic impacts on a residential property’s total possible gross revenue. Market Rents used by us in calculating Economic Occupancy are based on the current market rates set by the managers of our residential properties based on their experience in renting their residential property’s units and publicly available market data. Trends in market rents for a region as reported by

others could vary. Market Rents for a period are based on the average Market Rents during that period and do not reflect any impact for cash concessions.

Other Operating Income and Expense Items
Development and Management Services Revenue
Development and management services revenue decreased by approximately $5.1 million for the year ended December 31, 2019 compared to 2018. Development services revenue increased by approximately $7.8 million while management services revenue decreased by approximately $12.9 million. The increase in development services revenue was primarily related to an increase in development fees and fees associated with tenant improvement projects earned from a third-party owned project in the Washington, DC region.
On January 1, 2019, we adopted ASU 2016-02. As a result of the adoption, there were certain nonlease components (service income from tenants) that were reclassified on a prospective basis from this line item of our Consolidated Statements of Operations to lease revenue. For the year ended December 31, 2018, management services revenue included $11.3 million of service income from tenants. Excluding this reclassification, management services revenue would have decreased by approximately $1.6 million due primarily to a $4.5 million decrease in leasing commissions offset by a $2.9 million increase in other management services revenue. The decrease in leasing commissions was primarily from a Boston unconsolidated joint venture and a third-party managed building in New York City. The increase in other management services revenue was primarily due to property and asset management fees we earned from our Santa Monica Business Park unconsolidated joint venture, which we acquired on July 19, 2018.
General and Administrative Expense
General and administrative expense increased by approximately $19.1 million for the year ended December 31, 2019 compared to 2018 primarily due to compensation expense and other general and administrative expenses increasing by approximately $17.9 million and $1.2 million, respectively. The increase in compensation expense was related to (1) an approximately $10.0 million increase related to a decrease in capitalized wages as a result of (a) approximately $7.6 million attributable to no longer being able to capitalize internal leasing and legal wages related to successful lease execution, and (b) approximately $2.4 million of external legal costs that could no longer be capitalized and (2) an approximately $8.3 million increase in the value of our deferred compensation plan partially offset by an approximately $0.4 million decrease related to other compensation expenses. The decrease in capitalized wages is shown as an increase to general and administrative expense as some of these costs were capitalized and included in real estate assets on our Consolidated Balance Sheets (see below). The increase in other general and administrative expenses was primarily related to an increase in professional fees.
Wages directly related to the development of rental properties are capitalized and included in real estate assets on our Consolidated Balance Sheets and they are amortized over the useful lives of the applicable asset or lease term. On January 1, 2019, we adopted ASU 2016-02 and therefore, as a lessor, we may only capitalize incremental direct leasing costs. As a result, we no longer capitalize internal and external legal costs and internal leasing wages; instead, we are required to expense these and other non-incremental costs as incurred (See Note 2 to the Consolidated Financial Statements).

76


Capitalized wages for the year ended December 31, 2019 and 2018 were approximately $10.4 million and $18.0 million, respectively. These costs are not included in the general and administrative expenses discussed above.
Transaction Costs
Transaction costs increased by approximately $0.4 million for the year ended December 31, 2019 compared to 2018 due primarily to transaction costs related to the pursuit and formation of new joint ventures. In general, transaction costs relating to the formation of new and pending joint ventures and the pursuit of other transactions are expensed as incurred.
Depreciation and Amortization Expense
Depreciation expense may differ between BXP and BPLP as a result of previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor OP Unit redemptions by BPLP.  This accounting resulted in a step-up of the real estate assets at BXP that was allocated to certain properties.  The difference between the real estate assets of BXP as compared to BPLP for certain properties having an allocation of the real estate step-up will result in a corresponding difference in depreciation expense. For additional information see the Explanatory Note that follows the cover page of this Annual Report on Form 10-K.

On May 9, 2019, we commenced development of 325 Main Street in Cambridge, Massachusetts (See Note 3 to the Consolidated Financial Statements). As a result, during the year ended December 31, 2019, we recorded approximately $9.5 million of accelerated depreciation expense for the demolition of the building.

Direct Reimbursements of Payroll and Related Costs From Management Services Contracts and Payroll and Related Costs From Management Service Contracts
ASU 2016-08 “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations” updated the principal versus agent considerations and as a result we determined that amounts reimbursed for payroll and related costs received from third parties in connection with management services contracts should be reflected on a gross basis instead of on a net basis as we have determined that we are the principal under these arrangements. It is anticipated that these two financial statement line items will generally offset each other.
Other Income and Expense Items
Income from Unconsolidated Joint Ventures
For the year ended December 31, 2019 compared to 2018, income from unconsolidated joint ventures increased by approximately $44.4 million primarily due to an approximately $47.2 million gain on sale of real estate from the sale of 540 Madison Avenue and approximately $22.4 million of accelerated depreciation during the year ended December 31, 2018 that resulted in a decrease of approximately $4.5 million to our net income from our Metropolitan Square joint venture in Washington, DC that did not recur in 2019. These increases were partially offset by a gain on sale of real estate totaling approximately $8.3 million, recognized during the year ended December 31, 2018, related to the distribution of Annapolis Junction Building One.
On June 27, 2019, a joint venture in which we have a 60% interest completed the sale of its 540 Madison Avenue property located in New York City for a gross sale price of approximately $310.3 million, including the assumption by the buyer of the mortgage loan collateralized by the property totaling $120.0 million. Net cash proceeds totaled approximately $178.7 million, of which our share was approximately $107.1 million, after the payment of transaction costs. We recognized a gain on sale of real estate totaling approximately $47.2 million (See Note 5 to the Consolidated Financial Statements).
Gains on Sales of Real Estate
The gains on sales of real estate may differ between BXP and BPLP as a result of previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor OP Unit redemptions by BPLP. This accounting resulted in a step-up of the real estate assets at BXP that was allocated to certain properties. The difference between the real estate assets of BXP as compared to BPLP for certain properties having an allocation of the real estate step-up will result in a corresponding difference in the gains on sales of real estate when those properties are sold. For additional information, see the Explanatory Note that follows the cover page of this Form 10-K.

Interest and Other Income
Interest and other income increased by approximately $8.1 million for the year ended December 31, 2019 compared to 2018 due primarily to increased cash balances.
Gains (Losses) from Investments in Securities
Gains (losses) from investments in securities for the years ended December 31, 2019 and 2018 related to investments that we have made to reduce our market risk relating to deferred compensation plans that we maintain for BXP’s officers and non-employee directors. Under the deferred compensation plans, each officer or non-employee director who is eligible to participate is permitted to defer a portion of the officer’s current income or the non-employee director’s compensation on a pre-tax basis and receive a tax-deferred return on these deferrals based on the performance of specific investments selected by the officer or non-employee director. In order to reduce our market risk relating to these plans, we typically acquire, in a separate account that is not restricted as to its use, similar or identical investments as those selected by each officer or non-employee director. This enables us to generally match our liabilities to BXP’s officers or non-employee directors under our deferred compensation plans with equivalent assets and thereby limit our market risk. The performance of these investments is recorded as gains (losses) from investments in securities. During the years ended December 31, 2019 and 2018, we recognized gains (losses) of approximately $6.4 million and $(1.9) million, respectively, on these investments. By comparison, our general and administrative expense increased (decreased) by approximately $6.4 million and $(1.9) million during the years ended December 31, 2019 and 2018, respectively, as a result of increases (decreases) in our liability under our deferred compensation plans that was associated with the performance of the specific investments selected by officers and non-employee directors of BXP participating in the plans.
Impairment Losses
Impairment loss may differ between BXP and BPLP as a result of previously applied acquisition accounting by BXP for the issuance of common stock in connection with non-sponsor OP Unit redemptions by BPLP.  This accounting resulted in a step-up of the real estate assets at BXP that was allocated to certain properties.  The difference between the real estate assets of BXP as compared to BPLP for certain properties having an allocation of the real estate step-up will result in a corresponding difference in depreciation expense. For additional information see the Explanatory Note that follows the cover page of this Annual Report on Form 10-K.
At March 31, 2019, we evaluated the expected hold period of our One Tower Center property located in East Brunswick, New Jersey and, based on a shorter-than-expected hold period, we reduced the carrying value of the property to its estimated fair value at March 31, 2019 and recognized an impairment loss totaling approximately $24.0 million for BXP and approximately $22.3 million for BPLP. Our estimated fair value was based on a pending offer from a third party to acquire the property and the subsequent execution of a purchase and sale agreement on April 18, 2019 for a gross sale price of approximately $38.0 million (See Note 3 to the Consolidated Financial Statements). On June 3, 2019, we completed the sale of the property. One Tower Center is an approximately 410,000 net rentable square foot Class A office property.
On December 13, 2018, we completed the sale of our 6595 Springfield Center Drive development project located in Springfield, Virginia, for a sale price of approximately $98.1 million, consisting of the land and project costs incurred through the closing date. Net cash proceeds totaled approximately $97.1 million. Concurrently with the sale, we agreed to act as development manager and have guaranteed the completion of the project. The book value of the property exceeded its estimated fair value prior to the sale, and as a result, we recognized an impairment loss totaling approximately $8.7 million during the three months ended December 31, 2018. 6595 Springfield Center Drive is an approximately 634,000 net rentable square foot Class A office project.
During the three months ended December 31, 2018, we reevaluated our strategy for the sale of our 2600 Tower Oaks Boulevard property. Based on a shorter than expected hold period, we reduced the carrying value of the property to its estimated fair value at December 31, 2018 and recognized an impairment loss totaling approximately

80


$3.1 million for BXP and approximately $1.5 million for BPLP. Our estimated fair value was based on a pending offer for the sale of the property. 2600 Tower Oaks Boulevard is an approximately 179,000 net rentable square foot Class A office property (See Note 3 to the Consolidated Financial Statements).

Losses from Early Extinguishments of Debt
On December 19, 2019, we used available cash to repay the bond financing collateralized by our New Dominion Technology Park, Building One property totaling approximately $26.5 million. The bond financing bore interest at a weighted-average fixed rate of approximately 7.69% per annum and was scheduled to mature on January 15, 2021. We recognized a loss from early extinguishment of debt totaling approximately $1.5 million, which amount included the payment of a prepayment penalty totaling approximately $1.4 million. New Dominion Technology Park, Building One is an approximately 235,000 net rentable square foot Class A office property located in Herndon, Virginia (See Note 19 to the Consolidated Financial Statements).
On September 18, 2019, BPLP completed the redemption of $700.0 million in aggregate principal amount of its 5.625% senior notes due November 15, 2020. The redemption price was approximately $740.7 million. The redemption price included approximately $13.5 million of accrued and unpaid interest to, but not including, the redemption date. Excluding the accrued and unpaid interest, the redemption price was approximately 103.90% of the principal amount being redeemed. We recognized a loss from early extinguishment of debt totaling approximately $28.0 million, which amount included the payment of the redemption premium totaling approximately $27.3 million.
On December 13, 2018, BPLP completed the redemption of $700.0 million in aggregate principal amount of its 5.875% senior notes due October 15, 2019. The redemption price was approximately $722.6 million. The redemption price included approximately $6.6 million of accrued and unpaid interest to, but not including, the redemption date. Excluding the accrued and unpaid interest, the redemption price was approximately 102.28% of the principal amount being redeemed. We recognized a loss from early extinguishment of debt totaling approximately $16.5 million, which amount included the payment of the redemption premium totaling approximately $16.0 million.

Interest expense directly related to the development of rental properties is capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over the useful lives of the real estate or lease term. As portions of properties are placed in-service, we cease capitalizing interest on that portion and interest is then expensed. Interest capitalized for the years ended December 31, 2019 and 2018 was approximately $54.9 million and $65.8 million, respectively. These costs are not included in the interest expense referenced above.
At December 31, 2019, our outstanding variable rate debt consisted of BPLP’s $2.0 billion unsecured revolving credit facility (the “2017 Credit Facility”), which includes the $500.0 million delayed draw term loan facility (the “Delayed Draw Facility”) and the $1.5 billion revolving line of credit (the “Revolving Facility”). The Delayed Draw Facility had $500.0 million outstanding as of December 31, 2019. At December 31, 2019, the Revolving Facility did not have any borrowings outstanding. For a summary of our consolidated debt as of December 31, 2019 and December 31, 2018 refer to the heading “Liquidity and Capital Resources—Capitalization—Debt Financing” within “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations.

For BXP, noncontrolling interest—common units of the Operating Partnership decreased by approximately $7.5 million for the year ended December 31, 2019 compared to 2018 due primarily to a decrease in allocable income, which was the result of recognizing a greater gain on sales of real estate amount during 2018, partially offset by an increase in the noncontrolling interest’s ownership percentage. Due to our ownership structure, there is no corresponding line item on BPLP’s financial statements.

Liquidity and Capital Resources
General
Our principal liquidity needs for the next twelve months and beyond are to:
fund normal recurring expenses;
meet debt service and principal repayment obligations;
fund development/redevelopment costs;
fund capital expenditures, including major renovations, tenant improvements and leasing costs;
fund planned and possible acquisitions of properties, either directly or indirectly through the acquisition of equity interests therein;
fund dividend requirements on BXP’s Series B Preferred Stock; and
make the minimum distribution required to enable BXP to maintain its REIT qualification under the Internal Revenue Code of 1986, as amended.
We expect to satisfy these needs using one or more of the following:
cash flow from operations;
distribution of cash flows from joint ventures;
cash and cash equivalent balances;
BPLP’s 2017 Credit Facility and other short-term bridge facilities;
construction loans;
long-term secured and unsecured indebtedness (including unsecured exchangeable indebtedness);
sales of real estate; and
issuances of BXP equity securities and/or additional preferred or common units of partnership interest in BPLP.
We draw on multiple financing sources to fund our long-term capital needs. Our current development properties are expected to be primarily funded with our available cash balances, construction loans and BPLP’s Revolving Facility. We use BPLP’s Revolving Facility primarily as a bridge facility to fund acquisition opportunities, refinance outstanding indebtedness and meet short-term development and working capital needs. Although we may seek to fund our development projects with construction loans, which may require guarantees by BPLP, the financing for each particular project ultimately depends on several factors, including, among others, the project’s size and duration, the extent of pre-leasing and our available cash and access to cost effective capital at the given time.

Lease revenue (which includes recoveries from tenants), other income from operations, available cash balances, mortgage financings and draws on BPLP’s Revolving Facility are the principal sources of capital that we use to fund operating expenses, debt service, maintenance and repositioning capital expenditures, tenant improvements and the minimum distribution required to enable BXP to maintain its REIT qualification. We seek to maximize income from our existing properties by maintaining quality standards for our properties that promote high occupancy rates and permit increases in rental rates while reducing tenant turnover and controlling operating expenses. Our sources of revenue also include third-party fees generated by our property management, leasing and development and construction businesses, as well as the sale of assets from time to time. We believe our revenue, together with our cash balances and proceeds from financing activities, will continue to provide the funds necessary for our short-term liquidity needs, including our properties under development and redevelopment.
Material adverse changes in one or more sources of capital may adversely affect our net cash flows. In turn, these changes could adversely affect our ability to fund operating expenses, dividends and distributions, debt service payments, maintenance and repositioning capital expenditures and tenant improvements. In addition, a material adverse change in the cash provided by our operations may affect our ability to comply with the financial covenants under BPLP’s 2017 Credit Facility and unsecured senior notes.
Our primary uses of capital will be the completion of our current and committed development and redevelopment projects. As of December 31, 2019, our share of the remaining development and redevelopment costs that we expect to fund through 2024 is approximately $1.4 billion.
As of February 21, 2020, we have approximately $395 million of cash and cash equivalents, of which approximately $105 million is attributable to our consolidated joint venture partners, and approximately $1.5 billion available under BPLP’s Revolving Facility. We believe that our strong liquidity, including the availability under BPLP’s Revolving Facility, and proceeds from debt financings and asset sales will provide sufficient liquidity to fund our remaining capital requirements on existing development and redevelopment projects, fund pending new developments and still be able to act opportunistically on attractive investment opportunities. During the fourth quarter of 2019, we executed an agreement to sell our New Dominion Technology Park property located in Herndon, Virginia for a gross sale price of $256 million. The sale was completed on February 20, 2020. Excluding our unconsolidated joint venture assets, we have no debt maturing in 2020.
We have not sold any shares under BXP’s $600.0 million at the market (ATM) program.
We may seek to enhance our liquidity to provide sufficient capacity to fund our remaining capital requirements on existing development/redevelopment projects, our foreseeable potential development activity and pursue additional attractive investment opportunities. Depending on interest rates and overall conditions in the debt and equity markets, we may decide to access either or both of these markets in advance of the need for the funds. Doing so may result in us carrying additional cash and cash equivalents pending BPLP’s use of the proceeds, which would increase our net interest expense and be dilutive to our earnings.
REIT Tax Distribution Considerations
Dividend
BXP as a REIT is subject to a number of organizational and operational requirements, including a requirement that BXP currently distribute at least 90% of its annual taxable income (excluding capital gains and with certain other adjustments). Our policy is for BXP to distribute at least 100% of its taxable income, including capital gains, to avoid paying federal tax. On December 17, 2019, the Board of Directors of BXP increased our regular quarterly dividend from $0.95 per common share to $0.98 per common share, or 3%, beginning with the fourth quarter of 2019. Common and LTIP unitholders of limited partnership interest in BPLP, as of the close of business on December 31, 2019, received the same total distribution per unit on January 30, 2020.
BXP’s Board of Directors will continue to evaluate BXP’s dividend rate in light of our actual and projected taxable income, liquidity requirements and other circumstances, and there can be no assurance that the future dividends declared by BXP’s Board of Directors will not differ materially from the current quarterly dividend amount.
Sales
To the extent that we sell assets at a gain and cannot efficiently use the proceeds in a tax deferred manner for either our development activities or attractive acquisitions, BXP would, at the appropriate time, decide whether it is better to declare a special dividend, adopt a stock repurchase program, reduce indebtedness or retain the cash for

85


future investment opportunities. Such a decision will depend on many factors including, among others, the timing, availability and terms of development and acquisition opportunities, our then-current and anticipated leverage, the cost and availability of capital from other sources, the price of BXP’s common stock and REIT distribution requirements. At a minimum, we expect that BXP would distribute at least that amount of proceeds necessary for BXP to avoid paying corporate level tax on the applicable gains realized from any asset sales.
From time to time in selected cases, whether due to a change in use, structuring issues to comply with applicable REIT regulations or other reasons, we may sell an asset that is held by a taxable REIT subsidiary (“TRS”). Such a sale by a TRS would be subject to federal and local taxes.
Cash Flow Summary
The following summary discussion of our cash flows is based on the Consolidated Statements of Cash Flows and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below.
Cash and cash equivalents and cash held in escrows aggregated approximately $691.9 million and $639.2 million at December 31, 2019 and 2018, respectively, representing an increase of approximately $52.7 million. The following table sets forth changes in cash flows:

Our principal source of cash flow is related to the operation of our properties. The weighted-average term of our in-place tenant leases, including our unconsolidated joint ventures, is approximately 8.4 years with occupancy rates historically in the range of 90% to 94%. Our properties generate a relatively consistent stream of cash flow that provides us with resources to pay operating expenses, debt service and fund regular quarterly dividend and distribution payment requirements. In addition, over the past several years, we have raised capital through the sale of some of our properties and through secured and unsecured borrowings.
Cash is used in investing activities to fund acquisitions, development, net investments in unconsolidated joint ventures and maintenance and repositioning capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing and property management skills and invest in existing buildings to enhance or maintain their market position. Cash used in investing activities for the year ended December 31, 2019 consisted primarily of acquisitions of real estate, development projects, building and tenant improvements and capital contributions to unconsolidated joint ventures, partially offset by the proceeds from the sales of real estate and capital distributions from unconsolidated joint ventures. Cash used in investing activities for the year ended December 31, 2018 consisted primarily of development projects, building and tenant improvements, capital contributions to unconsolidated joint ventures and issuances of notes receivable, partially offset by the proceeds from the sales of real estate, as detailed below:

Cash used in investing activities changed primarily due to the following:

(1)
On January 10, 2019, we acquired land parcels at our Carnegie Center property located in Princeton, New Jersey for a gross purchase price of approximately $51.5 million, which includes an aggregate of approximately $8.6 million of additional amounts that are payable in the future to the seller upon the development or sale of each of the parcels.

87


On June 28, 2019, we completed the sale of our 164 Lexington Road property located in Billerica, Massachusetts for a gross sale price of $4.0 million. Net cash proceeds totaled approximately $3.8 million, resulting in a gain on sale of real estate totaling approximately $2.5 million for BXP and approximately $2.6 million for BPLP. 164 Lexington Road is an approximately 64,000 net rentable square foot Class A office property.
On September 20, 2019, we sold a 45% interest in our Platform 16 property located in San Jose, California for a gross sale price of approximately $23.1 million. Net cash proceeds totaled approximately $23.1 million. We ceased accounting for the property on a consolidated basis and now account for the property on an unconsolidated basis using the equity method of accounting, as we reduced our ownership interest and no longer have a controlling financial or operating interest in the property. We did not recognize a gain on the retained or sold interest in the property as the fair value of the property approximated its carrying value (See Notes 3, 5 and 19 to the Consolidated Financial Statements). Platform 16 consists of land totaling approximately 5.6 acres that will support the development of approximately 1.1 million square feet of commercial office space.
On December 20, 2019, we completed the sale of the remaining parcel of land at our Washingtonian North property located in Gaithersburg, Maryland for a gross sale price of approximately $7.8 million.

On May 24, 2018, we completed the sale of our 91 Hartwell Avenue property located in Lexington, Massachusetts for a gross sale price of approximately $22.2 million. Net cash proceeds totaled approximately $21.7 million, resulting in a gain on sale of real estate totaling approximately $15.5 million for BXP and approximately $15.9 million for BPLP. 91 Hartwell Avenue is an approximately 119,000 net rentable square foot Class A office property.
On September 27, 2018, we completed the sale of our Quorum Office Park property located in Chelmsford, Massachusetts for a gross sale price of approximately $35.3 million. Net cash proceeds totaled approximately $34.3 million, resulting in a gain on sale of real estate totaling approximately $7.9 million for BXP and approximately $9.2 million for BPLP.

On November 30, 2018, we completed the sale of our 1333 New Hampshire Avenue property located in Washington, DC for a gross sale price of approximately $142.0 million, including the retention of a $5.5 million future payment by the anchor tenant. Net cash proceeds totaled approximately $133.7 million, resulting in a gain on sale of real estate totaling approximately $44.4 million for BXP and approximately $48.4 million for BPLP. 1333 New Hampshire Avenue is an approximately 315,000 net rentable square foot Class A office property.
On December 13, 2018, we completed the sale of our 6595 Springfield Center Drive development project located in Springfield, Virginia, for a sale price of approximately $98.1 million, consisting of the land and project costs incurred through the closing date. Net cash proceeds totaled approximately $97.1 million. The book value of the property exceeded its estimated fair value prior to the sale, and as a result, we recognized an impairment loss totaling approximately $8.7 million during the three months ended December 31, 2018. 6595 Springfield Center Drive is an approximately 634,000 net rentable square foot Class A office project.
On December 20, 2018, we completed the sale of a 41-acre parcel of land at our Tower Oaks property located in Rockville, Maryland for a gross sale price of approximately $46.0 million. Net cash proceeds totaled approximately $25.9 million, resulting in a gain on sale of real estate totaling approximately $15.7 million. We have agreed to provide seller financing to the buyer totaling $21.0 million, which is collateralized by a portion of the land parcel, bears interest at an effective rate of 1.92% per annum and matures on December 20, 2021.

(6)
Issuance of related party note receivable consisted of the $80.0 million of mortgage financing that we provided to our unconsolidated joint venture that owns 3 Hudson Boulevard in New York City. The financing bears interest at a variable rate equal to LIBOR plus 3.50% per annum and matures on July 13, 2023, with extension options, subject to certain conditions.
(7)
Issuance of note receivable consisted of the $21.0 million of seller financing provided by us to the buyer in connection with the sale of land at our Tower Oaks property located in Rockville, Maryland, which is collateralized by a portion of the land parcel, bears interest at an effective rate of 1.92% per annum and matures on December 20, 2021.
Cash used in financing activities for the year ended December 31, 2019 totaled approximately $113.4 million. This consisted primarily of the proceeds from the issuance by BPLP of $850.0 million in aggregate principal amount of its 3.400% senior unsecured notes due 2029 and $700.0 million in aggregate principal amount of its 2.900% senior unsecured notes due 2030, partially offset by the redemption by BPLP of $700.0 million in aggregate principal amount of its 5.625% senior unsecured notes due 2020, the payment of our regular dividends and distributions to our shareholders and unitholders and the acquisition of our partner’s 5% ownership interest and promoted profits interest in the consolidated entity that owns Salesforce Tower located in San Francisco, California.

Consolidated Debt to Consolidated Market Capitalization Ratio is a measure of leverage commonly used by analysts in the REIT sector. We present this measure as a percentage and it is calculated by dividing (A) our consolidated debt by (B) our consolidated market capitalization, which is the market value of our outstanding equity securities plus our consolidated debt. Consolidated market capitalization is the sum of:
(1)     our consolidated debt; plus
(2)     the product of (x) the closing price per share of BXP common stock on December 31, 2019, as reported by the New York Stock Exchange, multiplied by (y) the sum of:
(i)
the number of outstanding shares of common stock of BXP,
(ii)
the number of outstanding OP Units in BPLP (excluding OP Units held by BXP),
(iii)
the number of OP Units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units, and
(iv)
the number of OP Units issuable upon conversion of 2012 OPP Units, 2013 MYLTIP Units, 2014 MYLTIP Units, 2015 MYLTIP Units and 2016 MYLTIP Units that were issued in the form of LTIP Units; plus
(3)     the aggregate liquidation preference ($2,500 per share) of the outstanding shares of BXP’s 5.25% Series B Cumulative Redeemable Preferred Stock.
The calculation of consolidated market capitalization does not include LTIP Units issued in the form of MYLTIP Awards unless and until certain performance thresholds are achieved and they are earned. Because their three-year performance periods have not yet ended, 2017, 2018 and 2019 MYLTIP Units (See Note 19 to the Consolidated Financial Statements) are not included in this calculation as of December 31, 2019.

We also present BXP’s Share of Market Capitalization and BXP’s Share of Debt/BXP’s Share of Market Capitalization, which are calculated in the same manner, except that BXP’s Share of Debt is utilized instead of our consolidated debt in both the numerator and the denominator. BXP’s Share of Debt is defined as our consolidated debt plus our share of debt from our unconsolidated joint ventures (calculated based upon our ownership percentage), minus our partners’ share of debt from our consolidated joint ventures (calculated based upon the partners’ percentage ownership interests adjusted for basis differentials). Management believes that BXP’s Share of Debt provides useful information to investors regarding our financial condition because it includes our share of debt from unconsolidated joint ventures and excludes our partners’ share of debt from consolidated joint ventures, in each case presented on the same basis. We have several significant joint ventures and presenting various measures of financial condition in this manner can help investors better understand our financial condition and/or results of operations after taking into account our economic interest in these joint ventures.  We caution investors that the ownership percentages used in calculating BXP’s Share of Debt may not completely and accurately depict all of the legal and economic implications of holding an interest in a consolidated or unconsolidated joint venture. For example, in addition to partners’ interests in profits and capital, venture agreements vary in the allocation of rights regarding decision making (both for routine and major decisions), distributions, transferability of interests, financing and guarantees, liquidations and other matters.  Moreover, in some cases we exercise significant influence over, but do not control, the joint venture in which case GAAP requires that we account for the joint venture entity using the equity method of accounting and we do not consolidate it for financial reporting purposes. In other cases, GAAP requires that we consolidate the venture even though our partner(s) own(s) a significant percentage interest.  As a result, management believes that the presentation of BXP’s Share of a financial measure should not be considered a substitute for, and should only be considered with and as a supplement to our financial information presented in accordance with GAAP.
We present these supplemental ratios because our degree of leverage could affect our ability to obtain additional financing for working capital, capital expenditures, acquisitions, development or other general corporate purposes and because different investors and lenders consider one or both of these ratios. Investors should understand that these ratios are, in part, a function of the market price of the common stock of BXP and as such will fluctuate with changes in such price, and they do not necessarily reflect our capacity to incur additional debt to finance our activities or our ability to manage our existing debt obligations. However, for a company like BXP, whose assets are primarily income-producing real estate, these ratios may provide investors with an alternate indication of leverage, so long as they are evaluated along with the ratio of indebtedness to other measures of asset value used by financial analysts and other financial ratios, as well as the various components of our outstanding indebtedness.
For a discussion of our unconsolidated joint venture indebtedness, see “Liquidity and Capital Resources—Capitalization—Off-Balance Sheet Arrangements—Joint Venture Indebtedness” within “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations.” and for a discussion of our consolidated joint venture indebtedness see “Liquidity and Capital Resources—Capitalization—Mortgage Notes Payable, Net” within “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
Debt Financing
As of December 31, 2019, we had approximately $11.8 billion of outstanding consolidated indebtedness, representing approximately 32.98% of our Consolidated Market Capitalization as calculated above consisting of approximately (1) $8.4 billion (net of discount and deferred financing fees) in publicly traded unsecured senior notes having a GAAP weighted-average interest rate of 3.76% per annum and maturities in 2021 through 2030, (2) $2.9 billion (net of deferred financing fees) of property-specific mortgage debt having a GAAP weighted-average interest rate of 3.90% per annum and weighted-average term of 6.3 years and (3) $498.9 million (net of deferred financing fees) outstanding under BPLP’s 2017 Credit Facility that matures on April 24, 2022.

Unsecured Credit Facility
On April 24, 2017, BPLP entered into the 2017 Credit Facility. Among other things, the 2017 Credit Facility (1) increased the total commitment of the Revolving Facility from $1.0 billion to $1.5 billion, (2) extended the maturity date from July 26, 2018 to April 24, 2022, (3) reduced the per annum variable interest rates, and (4) added a $500.0 million Delayed Draw Facility that permitted BPLP to draw until the first anniversary of the closing date. Based on BPLP’s current credit rating, (1) the applicable Eurocurrency margins for the Revolving Facility and Delayed Draw Facility are 82.5 basis points and 90 basis points, respectively, and (2) the facility fee on the Revolving Facility commitment is 0.125% per annum.
On April 24, 2018, BPLP exercised its option to draw $500.0 million on its Delayed Draw Facility. The Delayed Draw Facility bears interest at a variable rate equal to LIBOR plus 0.90% per annum based on BPLP’s December 31, 2019 credit rating and matures on April 24, 2022.

92


As of December 31, 2019 and February 21, 2020, BPLP had $500.0 million of borrowings outstanding under its Delayed Draw Facility, no borrowings under its Revolving Facility and letters of credit totaling approximately $2.5 million outstanding with the ability to borrow approximately $1.5 billion under the Revolving Facility.
Unsecured Senior Notes, Net
For a description of BPLP’s outstanding unsecured senior notes as of December 31, 2019, see Note 7 to the Consolidated Financial Statements.
On June 21, 2019, BPLP completed a public offering of $850.0 million in aggregate principal amount of its 3.400% unsecured senior notes due 2029. The notes were priced at 99.815% of the principal amount to yield an effective rate (including financing fees) of approximately 3.505% per annum to maturity. The notes will mature on June 21, 2029, unless earlier redeemed. The aggregate net proceeds from the offering were approximately $841.4 million after deducting underwriting discounts and transaction expenses.
On September 3, 2019, BPLP completed a public offering of $700.0 million in aggregate principal amount of its 2.900% unsecured senior notes due 2030. The notes were priced at 99.954% of the principal amount to yield an effective rate (including financing fees) of approximately 2.984% per annum to maturity. The notes will mature on March 15, 2030, unless earlier redeemed. The aggregate net proceeds from the offering were approximately $693.8 million after deducting underwriting discounts and transaction expenses.
On September 18, 2019, BPLP completed the redemption of $700.0 million in aggregate principal amount of its 5.625% senior notes due November 15, 2020. The redemption price was approximately $740.7 million. The redemption price included approximately $13.5 million of accrued and unpaid interest to, but not including, the redemption date. Excluding the accrued and unpaid interest, the redemption price was approximately 103.90% of the principal amount being redeemed. We recognized a loss from early extinguishment of debt totaling approximately $28.0 million, which amount included the payment of the redemption premium totaling approximately $27.3 million.
The indenture relating to the unsecured senior notes contains certain financial restrictions and requirements, including (1) a leverage ratio not to exceed 60%, (2) a secured debt leverage ratio not to exceed 50%, (3) an interest coverage ratio of greater than 1.50, and (4) an unencumbered asset value of not less than 150% of unsecured debt. At December 31, 2019, BPLP was in compliance with each of these financial restrictions and requirements.

GAAP interest rate differs from the stated interest rate due to the inclusion of the amortization of financing charges and the effects of hedging transactions (if any).
(2)
The mortgage loan requires interest only payments with a balloon payment due at maturity.
(3)
This property is owned by a consolidated entity in which we have a 60% interest. The partners’ share of the carrying amount has been adjusted for basis differentials.

(4)
In connection with the refinancing of the loan, we guaranteed the consolidated entity’s obligation to fund various reserves for tenant improvement costs and allowances, leasing commissions and free rent obligations in lieu of cash deposits. As of December 31, 2019, the maximum funding obligation under the guarantee was approximately $70.2 million. We earn a fee from the joint venture for providing the guarantee and have an agreement with our partners to reimburse the joint venture for their share of any payments made under the guarantee (See Note 9 to the Consolidated Financial Statements).

This property is owned by a consolidated entity in which we have a 55% interest.

Market Risk 
Market risk is the risk of loss from adverse changes in market prices and interest rates. Our future earnings, cash flows and fair values relevant to financial instruments are dependent upon prevalent market interest rates. Our primary market risk results from our indebtedness, which bears interest at fixed and variable rates. The fair value of our debt obligations are affected by changes in the market interest rates. We manage our market risk by matching long-term leases with long-term, fixed-rate, non-recourse debt of similar duration. We continue to follow a conservative strategy of generally pre-leasing development projects on a long-term basis to creditworthy tenants in order to achieve the most favorable construction and permanent financing terms. Approximately 95.8% of our outstanding debt, excluding our unconsolidated joint ventures, has fixed interest rates, which minimizes the interest rate risk through the maturity of such outstanding debt. We also manage our market risk by entering into hedging arrangements with financial institutions. Our primary objectives when undertaking hedging transactions and derivative positions is to reduce our floating rate exposure and to fix a portion of the interest rate for anticipated financing and refinancing transactions. This in turn, reduces the risks that the variability of cash flows imposes on variable rate debt. Our strategy mitigates against future increases in our interest rates.
At December 31, 2019, our weighted-average coupon/stated rate on our fixed rate outstanding Consolidated Debt was 3.69% per annum. At December 31, 2019, we had $500.0 million outstanding of consolidated variable rate debt. At December 31, 2019, the GAAP interest rate on our variable rate debt was approximately 2.75% per annum. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $5.0 million, on an annualized basis, for the year ended December 31, 2019.
Funds from Operations
Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“Nareit”), we calculate Funds from Operations, or “FFO,” for each of BXP and BPLP by adjusting net income (loss) attributable to Boston Properties, Inc. common shareholders and net income (loss) attributable to Boston Properties Limited Partnership common unitholders (computed in accordance with GAAP), respectively, for gains (or losses) from sales of properties, impairment losses on depreciable real estate consolidated on our balance sheet, impairment losses on our investments in unconsolidated joint ventures driven by a measurable decrease in the fair value of depreciable real estate held by the unconsolidated joint ventures and our share of real estate-related depreciation and amortization. FFO is a non-GAAP financial measure. We believe the presentation of FFO, combined with the presentation of required GAAP financial measures, has improved the understanding of operating results of REITs among the investing public and has helped make comparisons of REIT operating results more meaningful. Management generally considers FFO to be useful measures for understanding and comparing our operating results because, by excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment losses and real estate asset depreciation and amortization (which can differ across owners of similar assets in similar condition based on

94


historical cost accounting and useful life estimates), FFO can help investors compare the operating performance of a company’s real estate across reporting periods and to the operating performance of other companies.
Our computation of FFO may not be comparable to FFO reported by other REITs or real estate companies that do not define the term in accordance with the current Nareit definition or that interpret the current Nareit definition differently. We believe that in order to facilitate a clear understanding of our operating results, FFO should be examined in conjunction with net income attributable to Boston Properties, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership as presented in our Consolidated Financial Statements. FFO should not be considered as a substitute for net income attributable to Boston Properties, Inc. common shareholders or net income attributable to Boston Properties Limited Partnership common unitholders (determined in accordance with GAAP) or any other GAAP financial measures and should only be considered together with and as a supplement to our financial information prepared in accordance with GAAP.

Interest payments are calculated using the December 31, 2019 interest rate of 2.66%.
(3)
Committed tenant-related obligations based on executed leases as of December 31, 2019 (tenant improvements and lease commissions).
We have various service contracts with vendors related to our property management. In addition, we have certain other contracts we enter into in the ordinary course of business that may extend beyond one year. These contracts include terms that provide for cancellation with insignificant or no cancellation penalties. Contract terms are generally between three and five years. 
During 2019, we paid approximately $369.1 million to fund tenant-related obligations, including tenant improvements and leasing commissions.
In addition, we and our unconsolidated joint venture partners incurred approximately $547 million of new tenant-related obligations associated with approximately 7.0 million square feet of second generation leases, or approximately $78 per square foot. In addition, we signed leases for approximately 618,000 square feet at our development properties.  The tenant-related obligations for the development properties are included within the projects’ “Estimated Total Investment” referred to in “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.” In the aggregate, during 2019, we signed leases for approximately 7.6 million square feet of space and incurred aggregate tenant-related obligations of approximately $625 million, or approximately $82 per square foot.
Off-Balance Sheet Arrangements—Joint Venture Indebtedness
We have investments in unconsolidated joint ventures with our effective ownership interests ranging from 20% to 60%. Fourteen of these ventures have mortgage indebtedness. We exercise significant influence over, but do not control, these entities. As a result, we account for them using the equity method of accounting. See also Note 5 to the Consolidated Financial Statements. At December 31, 2019, the aggregate carrying amount of debt, including both our and our partners’ share, incurred by these ventures was approximately $2.2 billion (of which our proportionate share is approximately $980.1 million). The table below summarizes the outstanding debt of these joint venture properties at December 31, 2019. In addition to other guarantees specifically noted in the table, we have agreed to customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) as well as the completion of development projects on certain of the loans.

GAAP interest rate differs from the stated interest rate due to the inclusion of the amortization of financing charges, which includes mortgage recording fees.
(2)
The loan requires interest only payments with a balloon payment due at maturity.
(3)
The loan bears interest at a variable rate equal to LIBOR plus 1.28% per annum and matures on July 19, 2025. A subsidiary of the joint venture entered into interest rate swap contracts with notional amounts aggregating $300.0 million through April 1, 2025, resulting in a fixed rate of approximately 4.063% per annum through the expiration of the interest rate swap contracts.
(4)
The loan bears interest at a variable rate equal to LIBOR plus 2.00% per annum and matures on November 17, 2020.
(5)
The loan bears interest at a variable rate equal to LIBOR plus 2.35% per annum and matures on March 6, 2020.

(7)
The construction financing had a borrowing capacity of $204.6 million. On September 16, 2019, the joint venture paid down the construction loan principal balance in the amount of approximately $28.8 million, reducing the borrowing capacity to $175.8 million. The construction financing bears interest at a variable rate equal to LIBOR plus 2.25% per annum and matures on September 6, 2021, with two, one-year extension options, subject to certain conditions.
(8)
The construction financing has a borrowing capacity of $180.0 million. The construction financing bears interest at a variable rate equal to LIBOR plus 2.00% per annum and matures on April 19, 2022, with two, one-year extension options, subject to certain conditions.
(9)

The construction financing bears interest at a variable rate equal to LIBOR plus 1.50% per annum (LIBOR plus 1.375% per annum upon stabilization, as defined in the loan agreement) and matures on September 5, 2023, with two, one-year extension options, subject to certain conditions.

101


(10)
The construction financing has a borrowing capacity of $255.0 million. The construction financing bears interest at a variable rate equal to LIBOR plus 1.25% per annum and matures on April 26, 2023, with two, one-year extension options, subject to certain conditions.
(11)
We provided $80.0 million of mortgage financing to the joint venture. The loan bears interest at a variable rate equal to LIBOR plus 3.50% per annum and matures on July 13, 2023, with extension options, subject to certain conditions. The loan has been reflected as Related Party Note Receivable on our Consolidated Balance Sheets.
New Accounting Pronouncements
For a discussion of the new accounting pronouncements that may have an effect on our Consolidated Financial Statements (See Note 2 to the Consolidated Financial Statements).
Inflation 
Substantially all of our leases provide for separate real estate tax and operating expense escalations over a base amount. In addition, many of our leases provide for fixed base rent increases or indexed increases. We believe that inflationary increases in costs may be at least partially offset by the contractual rent increases and operating expense escalations.

Item 7A—Quantitative and Qualitative Disclosures about Market Risk.
The following table presents the aggregate carrying value of our mortgage notes payable, net, unsecured senior notes, net, unsecured line of credit, unsecured term loan, net and our corresponding estimate of fair value as of December 31, 2019. As of December 31, 2019, approximately $11.3 billion of these borrowings bore interest at fixed rates and therefore the fair value of these instruments is affected by changes in the market interest rates. As of December 31, 2019, the weighted-average interest rate on our variable rate debt was LIBOR plus 0.90% (2.66%) per annum. The following table presents our aggregate fixed rate debt obligations with corresponding weighted-average interest rates sorted by maturity date and our aggregate variable rate debt obligations sorted by maturity date.
The table below does not include our unconsolidated joint venture debt. For a discussion concerning our unconsolidated joint venture debt, see Note 5 to the Consolidated Financial Statements and “Item 7Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capitalization—Off-Balance Sheet Arrangements—Joint Venture Indebtedness.

At December 31, 2019, the coupon/stated rate on our variable rate debt was approximately 2.66% per annum. If market interest rates on our variable rate debt had been 100 basis points greater, total interest expense would have increased approximately $5.0 million, on an annualized basis, for the year ended December 31, 2019.
The fair value amounts were determined solely by considering the impact of hypothetical interest rates on our financial instruments. Due to the uncertainty of specific actions we may undertake to minimize possible effects of market interest rate increases, this analysis assumes no changes in our financial structure.
Due to the uncertainty of specific actions we may undertake to minimize possible effects of market interest rate increases, this analysis assumes no changes in our financial structure. In the event that LIBOR is discontinued, the interest rate for our variable rate debt and our unconsolidated joint ventures’ variable rate debt and the swap rate for our unconsolidated joint ventures’ interest rate swaps following such event will be based on an alternative variable rate as specified in the applicable documentation governing such debt or swaps or as otherwise agreed upon. Such an event would not affect our ability to borrow or maintain already outstanding borrowings or our unconsolidated joint ventures’ ability to maintain its outstanding swaps, but the alternative variable rate could be higher and more volatile than LIBOR prior to its discontinuance. We understand that LIBOR is expected to remain available through the end of 2021, but may be discontinued or otherwise become unavailable thereafter.

Management’s Report on Internal Control over
Financial Reporting
 
Management of Boston Properties, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting for Boston Properties, Inc. Boston Properties, Inc.’s internal control over financial reporting is a process designed under the supervision of its principal executive officer and principal financial officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of Boston Properties, Inc.’s financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles. 
As of the end of Boston Properties, Inc.’s 2019 fiscal year, management conducted assessments of the effectiveness of Boston Properties, Inc.’s internal control over financial reporting based on the framework established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on these assessments, management has determined that Boston Properties, Inc.’s internal control over financial reporting as of December 31, 2019 was effective. 
Our internal control over financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and the directors of Boston Properties, Inc.; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of Boston Properties, Inc.’s assets that could have a material effect on its financial statements. 
The effectiveness of Boston Properties, Inc.’s internal control over financial reporting as of December 31, 2019 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report appearing on page 106, which expresses an unqualified opinion on the effectiveness of Boston Properties, Inc.’s internal control over financial reporting as of December 31, 2019.

Report of Independent Registered Public Accounting Firm


To the Board of Directors and Stockholders of Boston Properties, Inc.
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Boston Properties, Inc. and its subsidiaries (the “Company”) as of December 31, 2019 and 2018, and the related consolidated statements of operations, of comprehensive income, of stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 2019, including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable

106


assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Impairment Assessment of Long-Lived Assets

As described in Notes 2 and 3 to the consolidated financial statements, the Company’s consolidated real estate, net balance was $17.6 billion as of December 31, 2019. During the period ended December 31, 2019, the Company recognized an impairment loss related to long lived assets totaling approximately $24.0 million. As described in Note 2 to the consolidated financial statements, management reviews its long-lived assets for impairment following the end of each quarter and when there is an event or change in circumstances that indicates that carrying amounts may not be recoverable. An impairment loss is recognized if the carrying amount of an asset is not recoverable and exceeds its fair value. As disclosed by management, the evaluation of anticipated cash flows is subjective and is based in part on assumptions regarding anticipated hold periods, future occupancy, future rental rates, future capital requirements, discount rates and capitalization rates that could differ materially from actual results in future periods.

The principal considerations for our determination that performing procedures relating to the impairment assessment of long-lived assets is a critical audit matter are (i) there was significant judgment by management in identifying events or changes in circumstances indicating that the carrying amounts of long-lived assets may not be recoverable, and to determine the hold period assumption used to assess whether the carrying amount of a long-lived asset was not recoverable, which led to a high degree of auditor judgment and subjectivity in performing procedures relating to the determination of those events or changes in circumstances and the hold period assumption; and (ii) there was significant auditor judgment and effort in evaluating the audit evidence.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the impairment assessment of long-lived assets, including controls over management’s identification of events or changes in circumstances that indicate an impairment of long-lived assets has occurred, and the development of significant assumptions used to determine the impairment loss. These procedures also included, among others, testing management’s process over (i) the identification of events or changes in circumstances that indicate an impairment of long lived assets has occurred; and (ii) developing the estimate of anticipated cash flows and estimate of the fair value of long-lived assets. Testing management’s process involved evaluating the reasonableness of the anticipated hold period assumption used by management, by considering; (i) the past performance of the asset; and (ii) whether the assumption was consistent with evidence obtained in other areas of the audit. Procedures were also performed to test the completeness and accuracy of the data utilized by management, and to evaluate the mathematical accuracy of the cash flows and impairment loss.

Management’s Report on Internal Control over
Financial Reporting
Management of Boston Properties, Inc., the sole general partner of Boston Properties Limited Partnership, is responsible for establishing and maintaining adequate internal control over financial reporting for Boston Properties Limited Partnership. Boston Properties Limited Partnership’s internal control over financial reporting is a process designed under the supervision of the principal executive officer and principal financial officer of Boston Properties, Inc. to provide reasonable assurance regarding the reliability of financial reporting and the preparation of Boston Properties Limited Partnership’s financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.
As of the end of Boston Properties Limited Partnership’s 2019 fiscal year, management conducted assessments of the effectiveness of Boston Properties Limited Partnership’s internal control over financial reporting based on the framework established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on these assessments, management has determined that Boston Properties Limited Partnership’s internal control over financial reporting as of December 31, 2019 was effective.
Boston Properties Limited Partnership’s internal control over financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and the directors of Boston Properties, Inc.; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of Boston Properties Limited Partnership’s assets that could have a material effect on our financial statements.
The effectiveness of Boston Properties Limited Partnership’s internal control over financial reporting as of December 31, 2019 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report appearing on page 118, which expresses an unqualified opinion on the effectiveness of Boston Properties Limited Partnership’s internal control over financial reporting as of December 31, 2019.

Report of Independent Registered Public Accounting Firm
 

To the Partners of Boston Properties Limited Partnership
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Boston Properties Limited Partnership and its subsidiaries (the “Partnership”) as of December 31, 2019 and 2018, and the related consolidated statements of operations, of comprehensive income, of capital and noncontrolling interests and of cash flows for each of the three years in the period ended December 31, 2019, including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the “consolidated financial statements”). We also have audited the Partnership's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Partnership as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2019 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Partnership maintained, in all material respects, effective internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Partnership's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Partnership’s consolidated financial statements and on the Partnership's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable

118


assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Impairment Assessment of Long-Lived Assets

As described in Notes 2 and 3 to the consolidated financial statements, the Partnership’s consolidated real estate, net balance was $17.3 billion as of December 31, 2019. During the period ended December 31, 2019, the Partnership recognized an impairment loss related to long lived assets totaling approximately $22.3 million. As described in Note 2 to the consolidated financial statements, management reviews its long-lived assets for impairment following the end of each quarter and when there is an event or change in circumstances that indicates that carrying amounts may not be recoverable. An impairment loss is recognized if the carrying amount of an asset is not recoverable and exceeds its fair value. As disclosed by management, the evaluation of anticipated cash flows is subjective and is based in part on assumptions regarding anticipated hold periods, future occupancy, future rental rates, future capital requirements, discount rates and capitalization rates that could differ materially from actual results in future periods.

The principal considerations for our determination that performing procedures relating to the impairment assessment of long-lived assets is a critical audit matter are (i) there was significant judgment by management in identifying events or changes in circumstances indicating that the carrying amounts of long-lived assets may not be recoverable, and to determine the hold period assumption used to assess whether the carrying amount of a long-lived asset was not recoverable, which led to a high degree of auditor judgment and subjectivity in performing procedures relating to the determination of those events or changes in circumstances and the hold period assumption; and (ii) there was significant auditor judgment and effort in evaluating the audit evidence.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the impairment assessment of long-lived assets, including controls over management’s identification of events or changes in circumstances that indicate an impairment of long-lived assets has occurred, and the development of significant assumptions used to determine the impairment loss. These procedures also included, among others, testing management’s process over (i) the identification of events or changes in circumstances that indicate an impairment of long lived assets has occurred; and (ii) developing the estimate of anticipated cash flows and estimate of the fair value of long-lived assets. Testing management’s process involved evaluating the reasonableness of the anticipated hold period assumption used by management, by considering; (i) the past performance of the asset; and (ii) whether the assumption was consistent with evidence obtained in other areas of the audit. Procedures were also performed to test the completeness and accuracy of the data utilized by management, and to evaluate the mathematical accuracy of the cash flows and impairment loss.

BOSTON PROPERTIES, INC. AND BOSTON PROPERTIES LIMITED PARTNERSHIP
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
1. Organization
Boston Properties, Inc., a Delaware corporation, is a fully integrated, self-administered and self-managed real estate investment trust (“REIT”). Boston Properties, Inc. is the sole general partner of Boston Properties Limited Partnership, its operating partnership and at December 31, 2019 owned an approximate 89.6% (89.7% at December 31, 2018) general and limited partnership interest in Boston Properties Limited Partnership. Unless stated otherwise or the context requires, the “Company” refers to Boston Properties, Inc. and its subsidiaries, including Boston Properties Limited Partnership and its consolidated subsidiaries. Partnership interests in Boston Properties Limited Partnership include:
common units of partnership interest (also referred to as “OP Units”),
long term incentive units of partnership interest (also referred to as “LTIP Units”), and
preferred units of partnership interest (also referred to as “Preferred Units”).
Unless specifically noted otherwise, all references to OP Units exclude units held by Boston Properties, Inc. A holder of an OP Unit may present such OP Unit to Boston Properties Limited Partnership for redemption at any time (subject to restrictions agreed upon at the time of issuance of OP Units to particular holders that may restrict such redemption right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, Boston Properties Limited Partnership is obligated to redeem the OP Unit for cash equal to the value of a share of common stock of Boston Properties, Inc. (“Common Stock”). In lieu of a cash redemption, Boston Properties, Inc. may elect to acquire the OP Unit for one share of Common Stock. Because the number of shares of Common Stock outstanding at all times equals the number of OP Units that Boston Properties, Inc. owns, one share of Common Stock is generally the economic equivalent of one OP Unit, and the quarterly distribution that may be paid to the holder of an OP Unit equals the quarterly dividend that may be paid to the holder of a share of Common Stock.
The Company uses LTIP Units as a form of equity-based award for annual long-term incentive equity compensation. The Company has also issued LTIP Units to employees in the form of (1) 2012 outperformance plan awards (“2012 OPP Units”) and (2) 2013, 2014, 2015, 2016, 2017, 2018 and 2019 multi-year, long-term incentive program awards (also referred to as “MYLTIP Units”), each of which, upon the satisfaction of certain performance and vesting conditions, is convertible into one OP Unit. The three-year measurement periods for the 2012 OPP Units, 2013 MYLTIP Units, 2014 MYLTIP Units, 2015 MYLTIP Units and 2016 MYLTIP Units expired on February 6, 2015, February 4, 2016, February 3, 2017, February 4, 2018 and February 9, 2019, respectively, and Boston Properties, Inc.’s total stockholder return (“TSR”) was sufficient for employees to earn and therefore become eligible to vest in a portion of the awards. Unless and until they are earned, the rights, preferences and privileges of the 2017 MYLTIP Units, 2018 MYLTIP Units and 2019 MYLTIP Units differ from other LTIP Units granted to employees (including the 2012 OPP Units, the 2013 MYLTIP Units, the 2014 MYLTIP Units, the 2015 MYLTIP Units and the 2016 MYLTIP Units, which have been earned). Therefore, unless specifically noted otherwise, all references to LTIP Units exclude the 2017 MYLTIP Units, 2018 MYLTIP Units and 2019 MYLTIP Units. LTIP Units (including the earned 2012 OPP Units, the 2013 MYLTIP Units, the 2014 MYLTIP Units, the 2015 MYLTIP Units and 2016 MYLTIP Units), whether vested or not, will receive the same quarterly per unit distributions as OP Units, which equal per share dividends on Common Stock (See Notes 10, 16 and 19).
At December 31, 2019, there was one series of Preferred Units outstanding (i.e., Series B Preferred Units). The Series B Preferred Units were issued to Boston Properties, Inc. on March 27, 2013 in connection with the issuance of 80,000 shares (8,000,000 depositary shares each representing 1/100th of a share) of 5.25% Series B Cumulative Redeemable Preferred Stock (the “Series B Preferred Stock”). Boston Properties, Inc. contributed the net proceeds from the offering to Boston Properties Limited Partnership in exchange for 80,000 Series B Preferred Units having terms and preferences generally mirroring those of the Series B Preferred Stock (See Note 11).
Properties
At December 31, 2019, the Company owned or had interests in a portfolio of 196 commercial real estate properties (the “Properties”) aggregating approximately 52.0 million net rentable square feet of primarily Class A office properties, including 11 properties under construction/redevelopment totaling approximately 5.5 million net rentable square feet. At December 31, 2019, the Properties consisted of:

129


177 office properties (including nine properties under construction/redevelopment);
twelve retail properties;
six residential properties (including two properties under construction); and
one hotel.
The Company considers Class A office properties to be well located buildings that are professionally managed and maintained, attract high-quality tenants and command upper-tier rental rates, and that are modern structures or have been modernized to compete with newer buildings.
Basis of Presentation
The accompanying consolidated financial statements are presented using the accrual basis of accounting in conformity with accounting principles generally accepted in the United States of America. Boston Properties, Inc. does not have any other significant assets, liabilities or operations, other than its investment in Boston Properties Limited Partnership, nor does it have employees of its own. Boston Properties Limited Partnership, not Boston Properties, Inc., generally executes all significant business relationships other than transactions involving securities of Boston Properties, Inc. All majority-owned subsidiaries and joint ventures over which the Company has financial and operating control and variable interest entities (“VIEs”) in which the Company has determined it is the primary beneficiary are included in the consolidated financial statements. All significant intercompany balances and transactions have been eliminated in consolidation. The Company accounts for all other unconsolidated joint ventures using the equity method of accounting. Accordingly, the Company’s share of the earnings of these joint ventures and companies is included in consolidated net income.
Variable Interest Entities (VIEs)
Consolidated VIEs are those for which the Company is considered to be the primary beneficiary of a VIE. The primary beneficiary is the entity that has a controlling financial interest in the VIE, which is defined by the entity having both of the following characteristics: (1) the power to direct the activities that, when taken together, most significantly impact the VIE’s performance and (2) the obligation to absorb losses or the right to receive the returns from the VIE that could potentially be significant to the VIE. The Company has determined that it is the primary beneficiary for six of the eight entities that are VIEs (see “New Accounting Pronouncements Issued but not yet Adopted—Consolidation” within Note 2).
Consolidated Variable Interest Entities
As of December 31, 2019, Boston Properties, Inc. has identified six consolidated VIEs, including Boston Properties Limited Partnership. Excluding Boston Properties Limited Partnership, the VIEs consisted of the following five in-service properties: 767 Fifth Avenue (the General Motors Building), Time Square Tower, 601 Lexington Avenue, Atlantic Wharf Office Building and 100 Federal Street.
The Company consolidates these VIEs because it is the primary beneficiary.  The third parties’ interests in these consolidated entities (i.e., excluding Boston Properties Limited Partnership’s interest) are reflected as noncontrolling interest in property partnerships in the accompanying Consolidated Financial Statements (See Note 10). 
In addition, Boston Properties, Inc.’s only significant asset is its investment in Boston Properties Limited Partnership and, consequently, substantially all of Boston Properties, Inc.’s assets and liabilities are the assets and liabilities of Boston Properties Limited Partnership.
Variable Interest Entities Not Consolidated
The Company has determined that Platform 16 Holdings LP and the landlord entity for its Platform 16 ground lease are VIEs. The Company does not consolidate these entities as the Company does not have the power to direct the activities that, when taken together, most significantly impact the VIE’s performance and, therefore, the Company is not considered to be the primary beneficiary.

2. Summary of Significant Accounting Policies
Real Estate 
Upon acquisitions of real estate, the Company assesses whether the transaction should be accounted for as an asset acquisition or as a business combination by applying a screen to determine whether the integrated set of assets and activities acquired meets the definition of a business. Acquisitions of integrated sets of assets and activities that do not meet the definition of a business are accounted for as asset acquisitions. The Company’s acquisitions of real estate or in-substance real estate generally will not meet the definition of a business because substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets (i.e. land, buildings, and related intangible assets) or because the acquisition does not include a substantive process in the form of an acquired workforce or an acquired contract that cannot be replaced without significant cost, effort or delay.
The Company assesses the fair value of acquired tangible and intangible assets (including land, buildings, tenant improvements, “above-” and “below-market” leases, leasing and assumed financing origination costs, acquired in-place leases, other identified intangible assets and assumed liabilities) and allocates the purchase price to the acquired assets and assumed liabilities, including land and buildings as if vacant. The Company assesses fair value based on estimated cash flow projections that utilize discount and/or capitalization rates that it deems appropriate, as well as available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known and anticipated trends, and market and economic conditions.
The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. The Company also considers an allocation of purchase price of other acquired intangibles, including acquired in-place leases that may have a customer relationship intangible value, including (but not limited to) the nature and extent of the existing relationship with the tenants, the tenants’ credit quality and expectations of lease renewals. Based on its acquisitions to date, the Company’s allocation to customer relationship intangible assets has been immaterial. 
The Company records acquired “above-” and “below-market” leases at their fair values (using a discount rate which reflects the risks associated with the leases acquired) equal to the difference between (1) the contractual amounts to be paid pursuant to each in-place lease and (2) management’s estimate of fair market lease rates for each corresponding in-place lease, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the term of any below-market fixed rate renewal options for below-market leases. Acquired “above-” and “below-market” lease values have been reflected within Prepaid Expenses and Other Assets and Other Liabilities, respectively, in the Company’s Consolidated Balance Sheets. Other intangible assets acquired include amounts for in-place lease values that are based on the Company’s evaluation of the specific characteristics of each tenant’s lease. Factors to be considered include estimates of carrying costs during hypothetical expected lease-up periods considering current market conditions, and costs to execute similar leases. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, depending on local market conditions. In estimating costs to execute similar leases, the Company considers leasing commissions, legal and other related expenses. 
Management reviews its long-lived assets for impairment following the end of each quarter and when there is an event or change in circumstances that indicates carrying amounts may not be recoverable. An impairment loss is recognized if the carrying amount of an asset is not recoverable and exceeds its fair value. The evaluation of anticipated cash flows is subjective and is based in part on assumptions regarding anticipated hold periods, future occupancy, future rental rates, future capital requirements, discount rates and capitalization rates that could differ materially from actual results in future periods. Because cash flows on properties considered to be “long-lived assets to be held and used” are considered on an undiscounted basis to determine whether an asset has been impaired, the Company’s established strategy of holding properties over the long term directly decreases the likelihood of recording an impairment loss. If the Company’s strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized and such loss could be material. If the Company determines that an impairment has occurred, the affected assets must be reduced to their fair value. 
Guidance in Accounting Standards Codification (“ASC”) 360 “Property Plant and Equipment” (“ASC 360”) requires that qualifying assets and liabilities and the results of operations that have been sold, or otherwise qualify as “held for sale,” be presented as discontinued operations in all periods presented if the property operations are expected to be eliminated and the Company will not have significant continuing involvement following the sale. Discontinued operations presentation applies only to disposals representing a strategic shift that has (or will have) a major effect on an entity’s operations and financial results (e.g., a disposal of a major geographical area, a major line of business, a

131


major equity method investment or other major parts of an entity). The components of the property’s net income that are reflected as discontinued operations include the net gain (or loss) upon the disposition of the property held for sale, operating results, depreciation and interest expense (if the property is subject to a secured loan). The Company generally considers assets to be “held for sale” when the transaction has been approved by Boston Properties, Inc.’s Board of Directors, or a committee thereof, and there are no known significant contingencies relating to the sale, such that a sale of the property within one year is considered probable. Following the classification of a property as “held for sale,” no further depreciation is recorded on the assets, and the asset is written down to the lower of carrying value or fair market value, less cost to sell.
Real estate is stated at depreciated cost. A variety of costs are incurred in the acquisition, development and leasing of properties. The cost of buildings and improvements includes the purchase price of property, legal fees and other acquisition costs. The Company capitalizes acquisition costs that it incurs to effect an asset acquisition and expenses acquisition costs that it incurs to effect a business combination, including legal, due diligence and other closing related costs. Costs directly related to the development of properties are capitalized. Capitalized development costs include interest, internal wages, property taxes, insurance, and other project costs incurred during the period of development. After the determination is made to capitalize a cost, it is allocated to the specific component of the project that benefited from the investment. Determination of when a development project commences and capitalization begins, and when a development project is substantially complete and held available for occupancy and capitalization must cease, involves a degree of judgment. The Company’s capitalization policy on development properties follows the guidance in ASC 835-20 “Capitalization of Interest” and ASC 970 “Real Estate-General.” The costs of land and buildings under development include specifically identifiable costs.
Capitalized costs include pre-construction costs necessary to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. The Company begins the capitalization of costs during the pre-construction period, which it defines as activities that are necessary for the development of the property. The Company considers a construction project as substantially complete and held available for occupancy upon the completion of tenant improvements, but no later than one year from cessation of major construction activity. The Company ceases capitalization on the portion (1) substantially completed, (2) occupied or held available for occupancy, and capitalizes only those costs associated with the portion under construction or (3) if activities necessary for the development of the property have been suspended. Interest costs capitalized for the years ended December 31, 2019, 2018 and 2017 were approximately $54.9 million, $65.8 million and $61.1 million, respectively. Salaries and related costs capitalized for the years ended December 31, 2019, 2018 and 2017 were approximately $10.4 million, $12.5 million and $13.2 million, respectively. 
Expenditures for repairs and maintenance are charged to operations as incurred. Significant betterments are capitalized. When assets are sold or retired, their costs and related accumulated depreciation are removed from the accounts with the resulting gains or losses reflected in net income or loss for the period. 
The Company computes depreciation and amortization on properties using the straight-line method based on estimated useful asset lives. The Company allocates the acquisition cost of real estate to its components and depreciates or amortizes these assets (or liabilities) over their useful lives. The amortization of acquired “above-” and “below-market” leases and acquired in-place leases is recorded as an adjustment to revenue and depreciation and amortization, respectively, in the Consolidated Statements of Operations. 
Depreciation is computed on a straight-line basis over the estimated useful lives of the assets as follows:
 
Land improvements
  
25 to 40 years
Buildings and improvements
  
10 to 40 years
Tenant improvements
  
Shorter of useful life or terms of related lease
Furniture, fixtures, and equipment
  
3 to 7 years
 
Cash and Cash Equivalents 
Cash and cash equivalents consist of cash on hand and investments with maturities of three months or less from the date of purchase. The majority of the Company’s cash and cash equivalents are held at major commercial banks which may at times exceed the Federal Deposit Insurance Corporation limit of $250,000.

132


Cash Held in Escrows
Escrows include amounts established pursuant to various agreements for security deposits, property taxes, insurance and other costs. Escrows also include cash held by qualified intermediaries for possible investments in like-kind exchanges in accordance with Section 1031 of the Internal Revenue Code, as amended (the “Code”), in connection with sales of the Company’s properties. 
Investments in Securities 
The Company accounts for investments in equity securities at fair value, with gains or losses resulting from changes in fair value recognized currently in earnings. The Company maintains deferred compensation plans that are designed to allow officers and non-employee directors of Boston Properties, Inc. to defer a portion of the officer’s current income or the non-employee director’s current compensation on a pre-tax basis and receive a tax-deferred return on these deferrals based on the performance of specific investments selected by the officer or non-employee director. The Company’s obligation under the plans is that of an unsecured promise to pay the deferred compensation to the plan participants in the future. At December 31, 2019 and 2018, the Company had maintained approximately $36.7 million and $28.2 million, respectively, in separate accounts, which are not restricted as to their use. The Company recognized gains (losses) of approximately $6.4 million, $(1.9) million and $3.7 million on its investments in the accounts associated with the Company’s deferred compensation plans during the years ended December 31, 2019, 2018 and 2017, respectively.
Tenant and Other Receivables
Tenant and other accounts receivable, other than accrued rents receivable, are expected to be collected within one year.
Notes Receivable
The Company accounts for notes receivable at their unamortized cost, net of any unamortized deferred fees or costs, premiums or discounts and an allowance for loan losses (see “New Accounting Pronouncements Issued but not yet Adopted—Financial Instruments - Credit Losses”). Loan fees and direct costs associated with loans originated by the Company are deferred and amortized over the term of the note as interest income. 
Deferred Charges
Deferred charges include leasing costs and certain financing fees. Leasing costs include acquired intangible in-place lease values and direct and incremental fees and costs incurred in the successful negotiation of leases, including brokerage and other costs which have been deferred and are being amortized on a straight-line basis over the terms of the respective leases. Unamortized leasing costs are charged to expense upon the early termination of the lease. Fully amortized deferred leasing costs are removed from the books upon the expiration of the lease. The Company did not capitalize any external legal costs and internal leasing salaries and related costs for the year ended December 31, 2019 (see “New Accounting Pronouncements Adopted—Leases”). Internal leasing salaries and related costs capitalized for the years ended December 31, 2018 and 2017 were approximately $5.4 million and $5.0 million, respectively. Financing fees included in deferred charges consist of external fees and costs incurred to obtain the Company’s revolving facility and if applicable, the delayed draw facility and construction financing arrangements where there are not sufficient amounts outstanding. Such financing costs have been deferred and are being amortized over the terms of the respective financing and included within interest expense. Unamortized financing costs are charged to expense upon the early repayment or significant modification of the financing. Fully amortized deferred financing costs are removed from the books upon the maturity of the debt.
External fees and costs incurred to obtain mortgage financings and unsecured senior notes have been deferred and are presented as direct deductions from the carrying amounts of the corresponding debt liability. Such financing costs are being amortized over the terms of the respective financing and included within interest expense. Unamortized financing costs are charged to expense upon the early repayment or significant modification of the financing.
Investments in Unconsolidated Joint Ventures 
The Company consolidates VIEs in which it is considered to be the primary beneficiary. VIEs are entities in which the equity investors do not have sufficient equity at risk to finance their endeavors without additional financial support or that the holders of the equity investment at risk do not have substantive participating rights. The primary beneficiary is defined by the entity having both of the following characteristics: (1) the power to direct the activities that, when taken

133


together, most significantly impact the variable interest entity’s performance, and (2) the obligation to absorb losses and the right to receive the returns from the variable interest entity that could potentially be significant to the VIE. For ventures that are not VIEs, the Company consolidates entities for which it has significant decision making control over the ventures’ operations. The Company’s judgment with respect to its level of influence or control of an entity involves the consideration of various factors including the form of the Company’s ownership interest, its representation in the entity’s governance, the size of its investment (including loans), estimates of future cash flows, its ability to participate in policy making decisions and the rights of the other investors to participate in the decision making process and to replace the Company as manager and/or liquidate the venture, if applicable. The Company’s assessment of its influence or control over an entity affects the presentation of these investments in the Company’s consolidated financial statements. In addition to evaluating control rights, the Company consolidates entities in which the outside partner has no substantive kick-out rights to remove the Company as the managing member. 
Accounts of the consolidated entity are included in the accounts of the Company and the noncontrolling interest is reflected on the Consolidated Balance Sheets as a component of equity or in temporary equity between liabilities and equity. Investments in unconsolidated joint ventures are recorded initially at cost, and subsequently adjusted for equity in earnings and cash contributions and distributions. Any difference between the carrying amount of these investments on the balance sheet and the underlying equity in net assets is amortized as an adjustment to equity in earnings of unconsolidated joint ventures over the life of the related asset. Under the equity method of accounting, the net equity investment of the Company is reflected within the Consolidated Balance Sheets, and the Company’s share of net income or loss from the joint ventures is included within the Consolidated Statements of Operations. The joint venture agreements may designate different percentage allocations among investors for profits and losses; however, the Company’s recognition of joint venture income or loss generally follows the joint venture’s distribution priorities, which may change upon the achievement of certain investment return thresholds. The Company may account for cash distributions in excess of its investment in an unconsolidated joint venture as income when the Company is not the general partner in a limited partnership and when the Company has neither the requirement nor the intent to provide financial support to the joint venture. The Company classifies distributions received from equity method investees within its Consolidated Statements of Cash Flows using the nature of the distribution approach, which classifies the distributions received on the basis of the nature of the activity or activities of the investee that generated the distribution as either a return on investment (classified as cash inflows from operating activities) or a return of investment (classified as cash inflows from investing activities). The Company’s investments in unconsolidated joint ventures are reviewed for impairment periodically and the Company records impairment charges when events or circumstances change indicating that a decline in the fair values below the carrying amounts has occurred and such decline is other-than-temporary. The evaluation of fair value is subjective and is based in part on assumptions regarding future occupancy, future rental rates, future capital requirements, discount rates and capitalization rates that could differ materially from actual results in future periods. The ultimate realization of the investment in unconsolidated joint ventures is dependent on a number of factors, including the performance of each investment and market conditions. The Company will record an impairment charge if it determines that a decline in the fair value below the carrying amount of an investment in an unconsolidated joint venture is other-than-temporary.
To the extent that the Company contributed assets to a joint venture, the Company’s investment in the joint venture was recorded at the Company’s cost basis in the assets that were contributed to the joint venture. To the extent that the Company’s cost basis is different than the basis reflected at the joint venture level, the basis difference is amortized over the life of the related asset and included in the Company’s share of equity in net income of the joint venture. In accordance with the provisions of ASC 610-20 “Gains and Losses from the Derecognition of Nonfinancial Assets” (“ASC 610-20”), the Company will recognize a full gain on both the retained and sold portions of real estate contributed or sold to a joint venture by recognizing its new equity method investment interest at fair value.
The combined summarized financial information of the unconsolidated joint ventures is disclosed in Note 5. 
Revenue Recognition
In general, the Company commences lease/rental revenue recognition when the tenant takes possession of the leased space and the leased space is substantially ready for its intended use. Contractual lease/rental revenue is reported on a straight-line basis over the terms of the respective leases. The impact of the straight-line rent adjustment increased revenue by approximately $58.4 million, $51.9 million and $54.8 million for the years ended December 31, 2019, 2018 and 2017, respectively, as the revenue recorded exceeded amounts billed. Accrued rental income, as reported on the Consolidated Balance Sheets, represents cumulative lease/rental income earned in excess of rent payments received pursuant to the terms of the individual lease agreements. The Company maintains an allowance against accrued rental income for future potential tenant credit losses. The credit assessment is based on the

134


estimated accrued rental income that is recoverable over the term of the lease. The Company also maintains an allowance for doubtful accounts for estimated losses resulting from the inability of tenants to make required rent payments. The computation of this allowance is based on the tenants’ payment history and current credit status, as well as certain industry or geographic specific credit considerations. If the Company’s estimates of collectability differ from the cash received, then the timing and amount of the Company’s reported revenue could be impacted. The credit risk is mitigated by the high quality of the Company’s existing tenant base, reviews of prospective tenants’ risk profiles prior to lease execution and consistent monitoring of the Company’s portfolio to identify potential problem tenants.
In accordance with ASC 805, the Company recognizes acquired in-place “above-” and “below-market” leases at their fair values as rental revenue over the original term of the respective leases. The impact of the acquired in-place “above-” and “below-market” leases increased revenue by approximately $20.9 million, $23.8 million and $23.5 million for the years ended December 31, 2019, 2018 and 2017, respectively. The following table summarizes the scheduled amortization of the Company’s acquired “above-” and “below-market” lease intangibles for each of the five succeeding years (in thousands).

Recoveries from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes and other recoverable costs, are recognized as revenue in the period during which the expenses are incurred (see “New Accounting Pronouncements Adopted—Leases”). The Company recognizes these reimbursements on a gross basis, as the Company obtains control of the goods and services before they are transferred to the tenant. The Company also receives reimbursements of payroll and payroll related costs from unconsolidated joint venture entities and third party property owners in connection with management services contracts which the Company reflects on a gross basis instead of on a net basis as the Company has determined that it is the principal and not the agent under these arrangements in accordance with the guidance in ASC 606 “Revenue from Contracts with Customers” (“ASC 606”).
The Company’s parking revenue is derived primarily from monthly and transient daily parking. In addition, the Company has certain lease arrangements for parking accounted for under the guidance in ASC 842 “Leases” (“ASC 842”). The monthly and transient daily parking revenue falls within the scope of ASC 606 and is accounted for at the point in time when control of the goods or services transfers to the customer and the Company’s performance obligation is satisfied.
The Company’s hotel revenue is derived from room rentals and other sources such as charges to guests for telephone service, movie and vending commissions, meeting and banquet room revenue and laundry services. Hotel revenue is recognized as the hotel rooms are occupied and the services are rendered to the hotel customers.
The Company earns management and development fees. Development and management services revenue is earned from unconsolidated joint venture entities and third-party property owners. The Company determined that the performance obligations associated with its development services contracts are satisfied over time and that the Company would recognize its development services revenue under the output method evenly over time from the development commencement date through the substantial completion date of the development management services project due to the stand-ready nature of the contracts. Significant judgments impacting the amount and timing of revenue recognized from the Company’s development services contracts include estimates of total development project costs from which the fees are typically derived and estimates of the period of time until substantial completion of the development project, the period of time over which the development services are required to be performed. The Company recognizes development fees earned from unconsolidated joint venture projects equal to its cost plus profit to the extent of the third party partners’ ownership interest. Property management fees are recorded and earned based on a percentage of collected rents at the properties under management, and not on a straight-line basis, because such fees are contingent upon the collection of rents.

135


Gains on sales of real estate are recognized pursuant to the provisions included in ASC 610-20. Under ASC 610-20, the Company must first determine whether the transaction is a sale to a customer or non-customer. The Company typically sells real estate on a selective basis and not within the ordinary course of its business and therefore expects that its sale transactions will not be contracts with customers. The Company next determines whether it has a controlling financial interest in the property after the sale, consistent with the consolidation model in ASC 810 “Consolidation” (“ASC 810”). If the Company determines that it does not have a controlling financial interest in the real estate, it evaluates whether a contract exists under ASC 606 and whether the buyer has obtained control of the asset that was sold. The Company recognizes a full gain on sale of real estate when the derecognition criteria under ASC 610-20 have been met.
Earnings Per Share 
Basic earnings per share (“EPS”) is computed by dividing net income available to common shareholders, as adjusted for undistributed earnings (if any) of certain securities issued by Boston Properties Limited Partnership, by the weighted average number of shares of Common Stock outstanding during the year. Diluted EPS reflects the potential dilution that could occur from shares issuable in connection with awards under stock-based compensation plans, including upon the exercise of stock options, and securities of Boston Properties Limited Partnership that are exchangeable for Common Stock.
Earnings Per Common Unit
Basic earnings per common unit is computed by dividing net income available to common unitholders, as adjusted for undistributed earnings (if any) of certain securities issued by Boston Properties Limited Partnership, by the weighted average number of common units outstanding during the year. Diluted earnings per common unit reflects the potential dilution that could occur from units issuable in connection with awards under Boston Properties, Inc.’s stock-based compensation plans, including upon the exercise of stock options, and conversion of preferred units of Boston Properties Limited Partnership.
Fair Value of Financial Instruments
The carrying values of cash and cash equivalents, marketable securities, escrows, receivables, accounts payable, accrued expenses and other assets and liabilities are reasonable estimates of their fair values because of the short maturities of these instruments.
The Company follows the authoritative guidance for fair value measurements when valuing its financial instruments for disclosure purposes. Boston Properties Limited Partnership determines the fair value of its unsecured senior notes using market prices. The inputs used in determining the fair value of Boston Properties Limited Partnership’s unsecured senior notes is categorized at a Level 1 basis (as defined in ASC 820 “Fair Value Measurements and Disclosures” (“ASC 820”)) due to the fact that it uses quoted market rates to value these instruments. However, the inputs used in determining the fair value could be categorized at a Level 2 basis (as defined in ASC 820) if trading volumes are low. The Company determines the fair value of its related party note receivable, note receivable and mortgage notes payable using discounted cash flow analysis by discounting the spread between the future contractual interest payments and hypothetical future interest payments on note receivables / mortgage debt based on current market rates for similar securities. In determining the current market rates, the Company adds its estimates of market spreads to the quoted yields on federal government treasury securities with similar maturity dates to its debt. The inputs used in determining the fair value of the Company’s related party note receivable, note receivable, and mortgage notes payable are categorized at a Level 3 basis (as defined in ASC 820) due to the fact that the Company considers the rates used in the valuation techniques to be unobservable inputs. To the extent that there are outstanding borrowings under the unsecured line of credit or unsecured term loan, the Company utilizes a discounted cash flow methodology in order to estimate the fair value. To the extent that credit spreads have changed since the origination, the net present value of the difference between future contractual interest payments and future interest payments based on the Company’s estimate of a current market rate would represent the difference between the book value and the fair value. The Company’s estimate of a current market rate is based upon the rate, considering current market conditions and Boston Properties Limited Partnership’s specific credit profile, at which it estimates it could obtain similar borrowings. To the extent there are outstanding borrowings, this current market rate is estimated and therefore would be primarily based upon a Level 3 input (see “New Accounting Pronouncements Issued but not yet Adopted—Fair Value Measurement”).

136


Because the Company’s valuations of its financial instruments are based on these types of estimates, the actual fair values of its financial instruments may differ materially if the Company’s estimates do not prove to be accurate, and the Company’s estimated fair values for these instruments as of the end of the applicable reporting period are not necessarily indicative of estimated or actual fair values in future reporting periods. The following table presents the aggregate carrying value of the Company’s related party note receivable, note receivable, mortgage notes payable, net, unsecured senior notes, net, unsecured line of credit and unsecured term loan, net and the Company’s corresponding estimate of fair value as of December 31, 2019 and December 31, 2018 (in thousands):

The Company uses interest rate swap agreements to manage its interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. To comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. Although the Company determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. The Company assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.
Derivative Instruments and Hedging Activities
Derivative instruments and hedging activities require management to make judgments on the nature of its derivatives and their effectiveness as hedges. These judgments determine if the changes in fair value of the derivative instruments are reported in the Consolidated Statements of Operations as a component of net income or as a component of comprehensive income and as a component of equity on the Consolidated Balance Sheets. While management believes its judgments are reasonable, a change in a derivative’s effectiveness as a hedge could materially affect expenses, net income and equity. The Company accounts for both the effective and ineffective portions of changes in the fair value of a derivative in other comprehensive income (loss) and subsequently reclassifies the fair value of the derivative to earnings over the term that the hedged transaction affects earnings and in the same line item as the hedged transaction within the statements of operations.
Stock-Based Employee Compensation Plans
At December 31, 2019, the Company has a stock-based employee compensation plan. The Company accounts for the plan under the guidance in ASC 718 “Compensation – Stock Compensation” (“ASC 718”), which revised the fair value based method of accounting for share-based payment liabilities, forfeitures and modifications of stock-based awards and clarified previous guidance in several areas, including measuring fair value, classifying an award as equity or as a liability and attributing compensation cost to reporting periods.

137


Use of Estimates in the Preparation of Financial Statements
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. These estimates include such items as depreciation and allowances for doubtful accounts. Actual results could differ from those estimates.
Out-of-Period Adjustment
During the year ended December 31, 2019, the Company recorded a change in the balance sheet classification of deferred stock units held by non-employee directors of Boston Properties, Inc. that are outstanding under Boston Properties, Inc.’s 1997 Stock Option and Incentive Plan and 2012 Stock Option and Incentive Plan (the “Plans”). The reclassification resulted from a modification to the terms of the non-employee director compensation program to provide, subject to certain conditions, the non-employee directors holding these units with the ability to elect, following cessation of their service on the Company’s Board of Directors, to diversify their investment elections into non-employer securities, which will ultimately be settled in cash. The modification required a change to the classification of these deferred stock units from permanent equity to temporary equity on the Consolidated Balance Sheets of Boston Properties, Inc. and Boston Properties Limited Partnership within Redeemable Deferred Stock Units. During the year ended December 31, 2019, the Company recorded a change in the balance sheet classification of certain deferred stock units outstanding to correct the approximately $8.4 million overstatement of each of Additional Paid-in Capital of Boston Properties, Inc. and Partners’ Capital of Boston Properties Limited Partnership, the approximately $8.1 million understatement of each of Redeemable Deferred Stock Units of Boston Properties, Inc. and Boston Properties Limited Partnership, and the approximately $0.3 million understatement of each of Accounts Payable and Accrued Expenses of Boston Properties, Inc. and Boston Properties Limited Partnership in the year ended December 31, 2018. Because this adjustment was not material to the prior year’s consolidated financial statements and the impact of recording the adjustment in the year ended December 31, 2019 was not material to Boston Properties, Inc.’s or Boston Properties Limited Partnership’s consolidated financial statements, the Company recorded the related adjustment during the year ended December 31, 2019. The out-of-period adjustment was identified and recorded during the three months ended September 30, 2019.
New Accounting Pronouncements Adopted
Leases    
General Adoption
In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). ASU 2016-02 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease for accounting purposes is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to the prior guidance in ASC 840 -“Leases” (“Topic 840”). ASU 2016-02 requires lessors to account for leases using an approach that is substantially equivalent to Topic 840 for sales-type leases, direct financing leases and operating leases. ASU 2016-02 supersedes previous leasing standards.
On July 30, 2018, the FASB issued ASU 2018-11, “Leases (Topic 842): Targeted Improvements” (“ASU 2018-11”), that (1) simplifies transition requirements for both lessees and lessors by adding an option that permits an organization to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented in its financial statements and (2) allows lessors to elect, as a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease component and, instead, to account for those components as a single component if the nonlease components otherwise would be accounted for under the revenue guidance in ASC 606 that was adopted on January 1, 2018, and both of the following are met:
(1) the timing and pattern of transfer of the nonlease component(s) and associated lease components are the same; and
(2) the lease component, if accounted for separately, would be classified as an operating lease.

138


If the nonlease component or components associated with the lease component are the predominant component of the combined component, an entity is required to account for the combined component in accordance with ASC 606.
The Company adopted ASU 2016-02 and ASU 2018-11 effective January 1, 2019. For purposes of transition, the Company elected the practical expedient package, which has been applied consistently to all of its leases, but did not elect the hindsight practical expedient. The practical expedient package did not require the Company to reassess the following: (i) whether an expired or existing contract meets the definition of a lease; (ii) the lease classification at the adoption date for existing leases; and (iii) whether costs previously capitalized as initial direct costs would continue to be amortized. This allows the Company to continue to account for its ground leases as operating leases. However, as of January 1, 2019, any new or modified ground leases may be classified as financing leases unless they meet certain conditions. The Company also elected to apply the transition provisions as of the adoption date, January 1, 2019, and not change its comparative statements. The Company recorded an adjustment to the opening balance of retained earnings related to initial direct costs that, as of January 1, 2019, had not started to amortize and are no longer allowed to be capitalized in accordance with ASU 2016-02, totaling approximately $3.9 million to Dividends in Excess of Earnings of Boston Properties, Inc. and Partners’ Capital of Boston Properties Limited Partnership, approximately $0.4 million to Noncontrolling interests - Common Units of Boston Properties, Inc. and Noncontrolling Interest - Redeemable Partnership Units of Boston Properties Limited Partnership and $70,000 to Noncontrolling Interests - Property Partnerships of Boston Properties, Inc. and Noncontrolling Interests in Property Partnerships of Boston Properties Limited Partnership on the corresponding Consolidated Balance Sheets.
The Company made the policy election, when it is the lessee, to not apply the revenue recognition requirements of Topic 842 to short-term leases. This policy election is made by class of underlying assets and as described below, the Company considers real estate to be a class of underlying assets, and will not be further delineating it into specific uses of the real estate asset as the risk profiles are similar in nature. The Company will recognize the lease payments in net income on a straight-line basis over the lease term.
Lease payments from operating leases are recognized on a straight-line basis over the term of the leases. The cumulative difference between lease revenue recognized under this method and the contractual lease payment terms is recorded as deferred rent receivable on the Company’s Consolidated Balance Sheets. The Company reviews its trade accounts receivable, including its straight-line rent receivable, related to base rents, straight-line rent, expense reimbursements and other revenues for collectability. The Company analyzes its accounts receivable, customer creditworthiness and current economic trends when evaluating the adequacy of the collectability of the lessee’s total accounts receivable balance on a lease-by-lease basis. In addition, tenants in bankruptcy are analyzed and considerations are made in connection with the expected recovery of pre-petition and post-petition claims. If a lessee’s accounts receivable balance is considered uncollectible, the Company will write-off the receivable balances associated with the lease to Lease revenue and cease to recognize lease income, including straight-line rent, unless cash is received. If the Company subsequently determines that it is probable it will collect substantially all the remaining lessee’s lease payments under the lease term, the Company will then reinstate the straight-line balance, adjusting for the amount related to the period when the lease payments were considered not probable. The Company’s reported net earnings are directly affected by management’s estimate of the collectability of its trade accounts receivable.
In January 2018, the FASB issued ASU 2018-01, “Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842” (“ASU 2018-01”), which provides an optional transition practical expedient to not evaluate, under Topic 842, existing or expired land easements that were not previously accounted for as leases under the leases guidance in Topic 840.  An entity that elects this practical expedient should evaluate new or modified land easements under Topic 842 beginning at the date that the entity adopts Topic 842.  An entity that does not elect this practical expedient should evaluate all existing or expired land easements in connection with the adoption of the new lease requirements in Topic 842 to assess whether they meet the definition of a lease.  The effective date and transition requirements for ASU 2018-01 are the same as the effective date and transition requirements in ASU 2016-02. The Company adopted ASU 2018-01 on January 1, 2019.
Lessee
For leases in which the Company is the lessee (generally ground leases), on January 1, 2019, the Company recognized a right-of-use asset and a lease liability of approximately $151.8 million and $199.3 million, respectively. The lease liability was equal to the present value of the minimum lease payments in accordance with Topic ASC 840. In addition, the Company did not know the rate implicit in any of its ground leases that were classified as operating leases, and accordingly used the Company’s incremental borrowing rate (“IBR”) to determine the net present value of the minimum lease payments.

139


In order to determine the IBR, the Company utilized a market-based approach to estimate the incremental borrowing rate for each individual lease. The approach required significant judgment. Therefore, the Company utilized different data sets to estimate base IBRs via an analysis of the following weighted-components: 
the interpolated rates from yields on outstanding U.S. Treasury issuances for up to 30 years and for years 31 and beyond, longer-term publicly traded educational institution debt issued by high credit quality educational institutions with maturity dates up to 2116,
observable mortgage rates spread over U.S. Treasury issuances, and
unlevered property yields and discount rates.
The Company then applied adjustments to account for considerations related to term and interpolated the IBR.
The Company has four non-cancelable ground lease obligations, which were classified as operating leases, with various initial term expiration dates through 2114. The Company recognizes ground rent expense on a straight-line basis over the term of the respective ground lease agreements. None of the amounts disclosed below for these ground leases contain variable payments, extension options or residual value guarantees. One of the ground leases does have an extension option. However, lease payments for this ground lease are based on fair market value and as such have not been included in the analysis below.
The Company has four finance lease obligations with various initial term expiration dates through 2094, see Note 3.

The finance leases relate to either land, buildings or assets that remain in development. For land leases classified as finance leases because of a purchase option that the Company views as an economic incentive, the Company follows its existing policy and does not depreciate land because it is assumed to have an indefinite life. For all other finance leases, the Company would amortize the right of use asset over the shorter of the useful life of the asset or the lease term. If the finance lease relates to a property under development, the amortization of the right of use asset may be eligible for capitalization. For assets under development, depreciation may commence once the asset is placed in-service and depreciation would be recognized in accordance with the Company’s policy.
(2)
Three of the finance leases relate to assets under development and as such, the entire interest amount was capitalized.

Finance lease payments in 2024 include approximately $38.7 million related to a purchase option that the Company is reasonably certain it will exercise.
Lessor
The Company leases primarily Class A office, retail and residential space to tenants. These leases may contain extension and termination options that are predominately at the sole discretion of the tenant, provided certain conditions are satisfied. In a few instances, the leases also contain purchase options, which would be exercisable at fair market value. Also, certain of the Company’s leases include rental payments that are based on a percentage of the tenant sales in excess of contractual amounts.

141


ASU 2018-11 provides lessors a practical expedient to not separate nonlease components from the associated lease component if certain criteria stated above are met for each class of underlying assets. The guidance in Topic 842 defines “underlying asset” as “an asset that is the subject of a lease for which a right to use that asset has been conveyed to a lessee. The underlying asset could be a physically distinct portion of a single asset.” Based on the above guidance, the Company considers real estate assets as a class of underlying assets and will not be further delineating it into specific uses of the real estate asset as the risk profiles are similar in nature.
Lease components are elements of an arrangement that provide the customer with the right to use an identified asset. Nonlease components are distinct elements of a contract that are not related to securing the use of the leased asset and revenue is recognized in accordance with ASC 606. The Company considers common area maintenance (CAM) and service income associated with tenant work orders to be nonlease components because they represent delivery of a separate service but are not considered a cost of securing the identified asset. In the case of the Company’s business, the identified asset would be the leased real estate (office, retail or residential).
The Company assessed and concluded that the timing and pattern of transfer for nonlease components and the associated lease component are the same. The Company determined that the predominant component was the lease component and as such its leases will continue to qualify as operating leases and the Company has made a policy election to account for and present the lease component and the nonlease component as a single component in the revenue section of the Consolidated Statements of Operations labeled Lease. Prior to the adoption of Topic 842, nonlease components had been included within Recoveries from Tenants Revenue, Parking and Other Revenue and Development and Management Services Revenue on the Company’s Consolidated Statements of Operations.
In addition, under ASU 2016-02, lessors will only capitalize incremental direct leasing costs. As a result, starting January 1, 2019, the Company no longer capitalizes non-incremental legal costs and internal leasing wages. These costs are expensed as incurred. The expensing of these items is included within General and Administrative Expense on the Consolidated Statements of Operations.

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date by replacing the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. In November 2018, the FASB issued ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses” (“ASU 2018-19”). ASU 2018-19 clarifies that receivables arising from operating leases are not within the scope of ASC 326-20, “Financial Instruments - Credit Losses - Measured at Amortized Cost,” which addresses financial assets measured at amortized cost basis, including net investments in leases arising from sales-type and direct financing leases. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with ASC 842. ASU 2016-13 and ASU 2018-19 are effective for the Company for reporting periods beginning after December 15, 2019, with early adoption permitted. ASU 2016-13 and ASU 2018-19 are applicable to the Company with respect to (1) certain of its accounts receivable, except for amounts arising from operating leases accounted for under ASC 842, (2) its related party note receivable, (3) its note receivable and (4) certain of its off-balance sheet credit exposures. The Company adopted ASU 2016-13 and ASU 2018-19 effective January 1, 2020 using the modified retrospective approach. The

142


adoption of ASU 2016-13 and ASU 2018-19 did not have a material impact on the Company’s consolidated financial statements.
Fair Value Measurement
In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”). ASU 2018-13 is intended to improve the effectiveness of disclosures required by entities regarding recurring and nonrecurring fair value measurements. ASU 2018-13 is effective for the Company for reporting periods beginning after December 15, 2019, with early adoption permitted. The adoption of ASU 2018-13 will not have a material impact on the Company’s consolidated financial statements.
Derivatives and Hedging
In October 2018, the FASB issued ASU 2018-16, “Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes” (“ASU 2018-16”). ASU 2018-16 permits the use of the overnight index swap rate based on the Secured Overnight Financing Rate (“SOFR”) to be used as a U.S. benchmark interest rate for purposes of applying hedge accounting under ASC 815. ASU 2018-16 is effective for the Company, which has already adopted ASU 2017-12, for reporting periods beginning after December 15, 2018 and is required to be adopted on a prospective basis for qualifying new or re-designated hedging relationships entered into on or after the date of adoption. The adoption of ASU 2018-16 will not have a material impact on the Company’s consolidated financial statements.
Consolidation
In October 2018, the FASB issued ASU 2018-17, “Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities” (“ASU 2018-17”). ASU 2018-17 is intended to improve the accounting when considering indirect interests held through related parties under common control for determining whether fees paid to decision makers and service providers are variable interests. ASU 2018-17 is effective for the Company for reporting periods beginning after December 15, 2019, with early adoption permitted. The adoption of ASU 2018-17 will not have a material impact on the Company’s consolidated financial statements.

Developments/Redevelopments
On May 9, 2019, the Company entered into a 15-year lease with Google, LLC for approximately 379,000 net rentable square feet of Class A office space in a build-to-suit development project located at the Company’s 325 Main Street property at Kendall Center in Cambridge, Massachusetts. 325 Main Street consisted of an approximately 115,000 net rentable square foot Class A office property that was demolished and is being developed into an approximately 420,000 net rentable square foot Class A office property, including approximately 41,000 net rentable square feet of retail space. On May 9, 2019, the Company commenced development of the project. Boston Properties, Inc. and Boston Properties Limited Partnership recognized approximately $9.9 million and $9.5 million, respectively, of depreciation expense associated with the acceleration of depreciation on the assets being removed from service and demolished as part of the redevelopment of the property.
On June 1, 2019, the Company partially placed in-service 20 CityPoint, a Class A office project with approximately 211,000 net rentable square feet located in Waltham, Massachusetts.

145


On September 30, 2019, the Company commenced the redevelopment of 200 West Street, a Class A office project with approximately 261,000 net rentable square feet located in Waltham, Massachusetts. The redevelopment is a conversion of a 126,000 square foot portion of the property to laboratory space.
On October 24, 2019, the Company completed and placed in-service 145 Broadway, a build-to-suit Class A office project with approximately 483,000 net rentable square feet located in Cambridge, Massachusetts.
Ground Leases
On January 24, 2019, the ground lessor under the Company’s 65-year ground lease for land totaling approximately 5.6 acres at Platform 16 located in San Jose, California made available for lease to the Company the remaining land parcels. As a result, the Company recognized the remaining portion of the right of use finance lease asset and finance lease liability. The Company entered into the ground lease in 2018, however, at the inception of the ground lease only a portion of the land was available for lease from the lessor, resulting in the Company recognizing only a portion of the ground lease. In the aggregate, the land will support the development of approximately 1.1 million square feet of commercial office space. The ground lease provides the Company with the right to purchase all of the land during a 12-month period commencing February 1, 2020 at a purchase price of approximately $134.8 million. The Company was reasonably certain it would exercise the option to purchase the land and as a result, the Company concluded that the lease should be accounted for as a finance lease. As a result, the Company recorded an approximately $122.6 million right of use asset - finance lease and a lease liability - finance lease on the Company’s Consolidated Balance Sheets reflecting the remaining land parcels made available for lease to the Company. Finance lease assets and liabilities are accounted for at the lower of fair market value or the present value of future lease payments. For land leases classified as finance leases because of a purchase option that the Company views as an economic incentive, the Company follows its existing policy and does not depreciate land because it is assumed to have an indefinite life. See also “Dispositions” below and Notes 5 and 19.
As of January 24, 2019, the lease payments from the finance lease related to the remaining parcels made available for lease to the Company were as follows (in thousands):

On July 16, 2019, the Company executed a 75-year ground lease with The George Washington University for land parcels at 2100 Pennsylvania Avenue located in Washington, DC and commenced development of an approximately 470,000 net rentable square foot Class A office property pursuant to a development agreement that the Company entered into with The George Washington University in 2016. The development agreement provided for the execution of the ground lease upon completion of the entitlement process and relocation of existing tenants. Also in 2016, the Company made a deposit of $15.0 million that, upon execution of the ground lease, is credited against ground rent payable under the ground lease. The present value of the lease payments exceeds substantially all of the fair value of the underlying asset and as a result, the Company has concluded that the ground lease should be accounted for as a finance lease. As a result, the Company recorded an approximately $185.1 million right of use asset - finance lease and an approximately $165.0 million lease liability - finance lease on the Company’s Consolidated Balance Sheets. The difference between the right of use asset - finance lease and lease liability - finance lease is the $15.0 million deposit that was made in 2016 and approximately $5.1 million of initial direct costs. Although the finance lease is for land only, as this was not classified as a finance lease because of a purchase option, the right of use asset will be amortized over the shorter of the useful life of the asset or the lease term. As land is assumed to have an indefinite life, the right of use asset - finance lease will be amortized on a straight-line basis over the 75-year term. In 2017, the Company entered into a 16-year lease with a tenant for approximately 300,000 net rentable square feet of space at the property.

Acquisitions
On January 10, 2019, the Company acquired land parcels at its Carnegie Center property located in Princeton, New Jersey for a gross purchase price of approximately $51.5 million, which includes an aggregate of approximately $8.6 million of additional amounts that are payable in the future to the seller upon the development or sale of each of the parcels. The land parcels could support approximately 1.7 million square feet of development.
On August 27, 2019, the Company acquired 880 and 890 Winter Street located in Waltham, Massachusetts for a gross purchase price of approximately $106.0 million in cash. 880 and 890 Winter Street consists of two Class A office properties aggregating approximately 392,000 net rentable square feet.

Dispositions
On January 24, 2019, the Company completed the sale of its 2600 Tower Oaks Boulevard property located in Rockville, Maryland for a gross sale price of approximately $22.7 million. Net cash proceeds totaled approximately $21.4 million, resulting in a loss on sale of real estate totaling approximately $0.6 million. The Company recognized an impairment loss totaling approximately $3.1 million for Boston Properties, Inc. and approximately $1.5 million for Boston Properties Limited Partnership during the year ended December 31, 2018. 2600 Tower Oaks Boulevard is an approximately 179,000 net rentable square foot Class A office property. 2600 Tower Oaks contributed approximately $(0.2) million of net loss to the Company for the period from January 1, 2019 through January 23, 2019 and contributed approximately $(0.6) million and $(0.1) million of net loss to the Company for the years ended December 31, 2018 and 2017, respectively.
At March 31, 2019, the Company evaluated the expected hold period of its One Tower Center property located in East Brunswick, New Jersey and, based on a shorter-than-expected hold period, the Company reduced the carrying value of the property to its estimated fair value at March 31, 2019 and recognized an impairment loss totaling approximately $24.0 million for Boston Properties, Inc. and approximately $22.3 million for Boston Properties Limited Partnership. The Company’s estimated fair value was based on a pending offer from a third party to acquire the property and the subsequent execution of a purchase and sale agreement on April 18, 2019 for a gross sale price of $38.0 million. On June 3, 2019, the Company completed the sale of the property. Net cash proceeds totaled approximately $36.6 million, resulting in a loss on sale of real estate totaling approximately $0.8 million. One Tower Center is an approximately 410,000 net rentable square foot Class A office property. One Tower Center contributed approximately $(0.9) million of net loss to the Company for the period from January 1, 2019 through June 2, 2019 and contributed approximately $(2.7) million and $(3.5) million of net loss to the Company for the years ended December 31, 2018 and 2017, respectively.
On June 28, 2019, the Company completed the sale of its 164 Lexington Road property located in Billerica, Massachusetts for a gross sale price of $4.0 million. Net cash proceeds totaled approximately $3.8 million, resulting in a gain on sale of real estate totaling approximately $2.5 million for Boston Properties, Inc. and approximately $2.6 million for Boston Properties Limited Partnership. 164 Lexington Road is an approximately 64,000 net rentable square foot Class A office property. 164 Lexington Road contributed approximately $(0.1) million of net loss to the Company for the period from January 1, 2019 through June 27, 2019 and contributed approximately $(0.2) million and $(0.2) million of net loss to the Company for the years ended December 31, 2018 and 2017, respectively.
On September 20, 2019, the Company entered into a joint venture with Canada Pension Plan Investment Board (“CPPIB”) to develop Platform 16 located in San Jose, California. Platform 16 consists of a 65-year ground lease for land totaling approximately 5.6 acres that will support the development of approximately 1.1 million square feet of commercial office space. During 2018, the Company entered into the ground lease, which provides for the right to purchase all of the land during a 12-month period commencing February 1, 2020 at a purchase price of approximately $134.8 million. The Company contributed the ground lease interest and improvements totaling approximately $28.2 million for its initial 55% interest in the joint venture. CPPIB contributed cash totaling approximately $23.1 million for its initial 45% interest in the joint venture. Upon the CPPIB contribution, the Company ceased accounting for the joint venture entity on a consolidated basis and is accounting for the joint venture entity on an unconsolidated basis using the equity method of accounting, as it has reduced its ownership interest and no longer has a controlling financial or operating interest in the joint venture entity (See Note 5). The Company did not recognize a gain on the retained or sold interest in the real estate contributed to the joint venture, as the fair value of the real estate approximated its carrying value.
On December 20, 2019, the Company completed the sale of the remaining parcel of land at its Washingtonian North property located in Gaithersburg, Maryland for a gross sale price of approximately $7.8 million. Net cash proceeds totaled approximately $7.3 million, resulting in a loss on sale of real estate totaling approximately $0.1 million. The Company recognized an impairment loss totaling approximately $1.8 million during the year ended December 31, 2016.

8. Unsecured Credit Facility
On April 24, 2017, Boston Properties Limited Partnership amended and restated its unsecured revolving credit agreement (as amended and restated, the “2017 Credit Facility”). Among other things, the 2017 Credit Facility (1) increased the total commitment of the revolving line of credit (the “Revolving Facility”) from $1.0 billion to $1.5 billion, (2) extended the maturity date from July 26, 2018 to April 24, 2022, (3) reduced the per annum variable interest rates, and (4) added a $500.0 million delayed draw term loan facility (the “Delayed Draw Facility”) that permitted Boston Properties Limited Partnership to draw upon it provided that amounts drawn and subsequently repaid may not be borrowed again. In addition, Boston Properties Limited Partnership may increase the total commitment under the 2017 Credit Facility by up to $500.0 million through increases in the Revolving Facility or the Delayed Draw Facility, or both, subject to syndication of the increase and other conditions.
On April 24, 2018, Boston Properties Limited Partnership exercised its option to draw $500.0 million on its Delayed Draw Facility. The Delayed Draw Facility bears interest at a variable rate equal to LIBOR plus 0.90% per annum based on Boston Properties Limited Partnership’s current credit rating and matures on April 24, 2022.
At Boston Properties Limited Partnership’s option, loans under the Revolving Facility and Delayed Draw Facility will bear interest at a rate per annum equal to (1) (a) in the case of loans denominated in Dollars, Euro or Sterling, LIBOR, and (b) in the case of loans denominated in Canadian Dollars, CDOR, in each case, plus a margin ranging from 77.5 to 155 basis points for the Revolving Commitment and 85 to 175 basis points for the Delayed Draw Facility, based on Boston Properties Limited Partnership’s credit rating or (2) an alternate base rate equal to the greatest of (x) the Administrative Agent’s prime rate, (y) the Federal Funds rate plus 0.50% or (z) LIBOR for a one-month period plus 1.00%, in each case, plus a margin ranging from 0 to 55 basis points for the Revolving Facility and 0 to 75 basis points for the Delayed Draw Facility, based on Boston Properties Limited Partnership’s credit rating. The 2017 Credit Facility also contains a competitive bid option for up to 65% of the Revolving Facility that allows banks that are part of the lender consortium to bid to make loan advances to Boston Properties Limited Partnership at a reduced interest rate.
In addition, Boston Properties Limited Partnership is obligated to pay (1) in quarterly installments a facility fee on the total commitment under the Revolving Facility at a rate per annum ranging from 0.10% to 0.30% based on Boston Properties Limited Partnership’s credit rating, (2) an annual fee on the undrawn amount of each letter of credit equal to the LIBOR margin on the Revolving Facility and (3) a fee on the unused commitments under the Delayed Draw Facility equal to 0.15% per annum. Based on Boston Properties Limited Partnership’s December 31, 2019 credit rating, (1) the applicable Eurocurrency margins for the Revolving Facility and Delayed Draw Facility are 0.825% and 0.90%, respectively, (2) the alternate base rate margin is zero basis points for each of the Revolving Facility and Delayed Draw Facility and (3) the facility fee on the Revolving Facility commitment is 0.125% per annum.
At December 31, 2019 and 2018, Boston Properties Limited Partnership had $500.0 million of borrowings outstanding under its Delayed Draw Facility and no amounts outstanding under its Revolving Facility.
The 2017 Credit Facility contains customary representations and warranties, affirmative and negative covenants and events of default provisions, including failure to pay indebtedness, breaches of covenants, and bankruptcy and other insolvency events, which could result in the acceleration of all amounts and cancellation of all commitments outstanding under the Credit Agreement. Among other covenants, the 2017 Credit Facility requires that Boston Properties Limited Partnership maintain on an ongoing basis: (1) a leverage ratio not to exceed 60%, however, the leverage ratio may increase to no greater than 65% provided that it is reduced back to 60% within one

155


year, (2) a secured debt leverage ratio not to exceed 55%, (3) a fixed charge coverage ratio of at least 1.40, (4) an unsecured debt leverage ratio not to exceed 60%, however, the unsecured debt leverage ratio may increase to no greater than 65% provided that it is reduced to 60% within one year, (5) an unsecured debt interest coverage ratio of at least 1.75 and (6) limitations on permitted investments. At December 31, 2019, Boston Properties Limited Partnership was in compliance with each of these financial and other covenant requirements.

Pursuant to the lease agreement with Marriott, the Company has guaranteed the completion of the office building and parking garage on behalf of its 7750 Wisconsin Avenue joint venture and has also agreed to provide any financing guaranty that may be required with respect to third-party construction financing.  The Company earns fees from the joint venture for providing the guarantees and any amounts the Company pays under the guarantee(s) will be deemed to be capital contributions by the Company to the joint venture.  The Company has also agreed to fund construction costs through capital contributions to the joint venture in the event of unavailability or insufficiency of third-party construction financing.  In addition, the Company has guaranteed to Marriott, as hotel manager, the completion of a hotel being developed by an affiliate of The Bernstein Companies (the Company’s partner in the 7750 Wisconsin Avenue joint venture) adjacent to the office property, for which the Company earns a fee from the affiliate of The Bernstein Companies.  In addition, the Company entered into agreements with affiliates of The Bernstein Companies whereby the Company could be required to act as a mezzanine and/or mortgage lender and finance the construction of the hotel property.  To secure such financing arrangements, affiliates of The Bernstein Companies are required to provide certain security, which varies depending on the specific loan, by pledges of their equity interest in the office property, a fee mortgage on the hotel property, or both. As of December 31, 2019, no amounts related to the contingent aspect of any of the guarantees are recorded as liabilities in the Company’s consolidated financial statements.

In connection with the sale and development of the Company’s 6595 Springfield Center Drive development project, the Company has guaranteed the completion of the project and the payment of certain cost overruns in accordance with the development management agreement with the buyer. Although the project has been sold and the lease with the Federal Government tenant has been assigned to the buyer, pursuant to the terms of the Federal Government lease, the Federal Government tenant is not obligated to release the prior owner/landlord from such landlord’s obligations under the lease until completion of the construction. As a result, the entity which previously owned the land remains liable to the Federal Government tenant for the completion of the construction obligations under the lease.  The buyer is obligated to fund the balance of the costs to meet such construction obligations, subject to the Company’s obligation to fund cost overruns (if any), as noted above. An affiliate of the buyer has provided a guaranty of the obligations of the buyer to fund such construction costs and the buyer has agreed to use commercially reasonable efforts to require the construction lender to provide certain remedies to the Company in the event the buyer does not fund such construction obligations. As of December 31, 2019, no amounts related to the contingent aspect of the guarantee are recorded as a liability in the Company’s consolidated financial statements (See Note 3).
In connection with the redevelopment of the Company’s 325 Main Street property located in Cambridge, Massachusetts, the Company is required, pursuant to the local zoning ordinance, to commence construction of a residential building of at least 200,000 square feet with 25% of the project designated as income-restricted (with a minimum of 20% of the square footage devoted to home ownership units) prior to the occupancy of the 325 Main Street property. 325 Main Street consisted of an approximately 115,000 net rentable square foot Class A office property that was demolished and is being developed into an approximately 420,000 net rentable square foot Class A office property, including approximately 41,000 net rentable square feet of retail space (See Note 3).
In 2009, the Company filed a general unsecured creditor’s claim against Lehman Brothers, Inc. for approximately $45.3 million related to its rejection of a lease at 399 Park Avenue in New York City. On January 10, 2014, the trustee for the liquidation of the business of Lehman Brothers allowed the Company’s claim in the amount of approximately $45.2 million. During the years 2014 through 2018, the Company received distributions aggregating approximately $18.0 million, leaving a remaining claim of approximately $27.2 million. The Company will continue to evaluate whether to attempt to sell the remaining claim or wait until the trustee distributes proceeds from the Lehman Brothers estate. Given the inherent uncertainties in bankruptcy proceedings, there can be no assurance as to the timing or amount of additional proceeds, if any, that the Company may ultimately realize on the remaining claim, whether by sale to a third party or by one or more distributions from the trustee. Accordingly, the Company has not recorded any estimated recoveries associated with this gain contingency within its Consolidated Financial Statements at December 31, 2019.
Concentrations of Credit Risk 
Management of the Company performs ongoing credit evaluations of tenants and may require tenants to provide some form of credit support such as corporate guarantees and/or other financial guarantees. Although the Company’s properties are geographically diverse and the tenants operate in a variety of industries, to the extent the Company has a significant concentration of rental revenue from any single tenant, the inability of that tenant to make its lease payments could have an adverse effect on the Company. 
Insurance
The Company’s property insurance program per occurrence limits are $1.0 billion for its portfolio insurance program, including coverage for acts of terrorism other than nuclear, biological, chemical or radiological terrorism (“Terrorism Coverage”). The Company also carries $250 million of Terrorism Coverage for 601 Lexington Avenue, New York, New York (“601 Lexington Avenue”) in excess of the $1.0 billion of coverage in the Company’s property insurance program. Certain properties, including the General Motors Building located at 767 Fifth Avenue in New York, New York (“767 Fifth Avenue”), are currently insured in separate insurance programs. The property insurance program per occurrence limits for 767 Fifth Avenue are $1.625 billion, including Terrorism Coverage. The Company also currently carries nuclear, biological, chemical and radiological terrorism insurance coverage for acts of terrorism certified under the Federal Terrorism Risk Insurance Act (as amended, “TRIA”) (“NBCR Coverage”), which is provided by IXP as a direct insurer, for the properties in the Company’s portfolio, including 767 Fifth Avenue, but excluding certain other properties owned in joint ventures with third parties or which the Company manages. The per occurrence limit for NBCR Coverage is $1.0 billion. Under TRIA, after the payment of the required deductible and coinsurance, the NBCR Coverage provided by IXP is backstopped by the Federal Government if the aggregate industry insured losses resulting from a certified act of terrorism exceed a “program trigger.” In 2019, the program trigger was $180 million and the coinsurance was 19%, however, both will increase in subsequent years pursuant to

157


TRIA. If the Federal Government pays out for a loss under TRIA, it is mandatory that the Federal Government recoup the full amount of the loss from insurers offering TRIA coverage after the payment of the loss pursuant to a formula in TRIA. The Company may elect to terminate the NBCR Coverage if the Federal Government seeks recoupment for losses paid under TRIA, if TRIA is not extended after its expiration on December 31, 2027, if there is a change in its portfolio or for any other reason. The Company intends to continue to monitor the scope, nature and cost of available terrorism insurance.
The Company also currently carries earthquake insurance on its properties located in areas known to be subject to earthquakes. In addition, this insurance is subject to a deductible in the amount of 3% of the value of the affected property. Specifically, the Company currently carries earthquake insurance which covers its San Francisco and Los Angeles regions with a $240 million per occurrence limit, and a $240 million annual aggregate limit, $20 million of which is provided by IXP, as a direct insurer. The amount of the Company’s earthquake insurance coverage may not be sufficient to cover losses from earthquakes. In addition, the amount of earthquake coverage could impact the Company’s ability to finance properties subject to earthquake risk. The Company may discontinue earthquake insurance or change the structure of its earthquake insurance program on some or all of its properties in the future if the premiums exceed the Company’s estimation of the value of the coverage.
IXP, a captive insurance company which is a wholly-owned subsidiary of the Company, acts as a direct insurer with respect to a portion of the Company’s earthquake insurance coverage for its Greater San Francisco and Los Angeles properties and the Company’s NBCR Coverage. Insofar as the Company owns IXP, it is responsible for its liquidity and capital resources, and the accounts of IXP are part of the Company’s consolidated financial statements. In particular, if a loss occurs which is covered by the Company’s NBCR Coverage but is less than the applicable program trigger under TRIA, IXP would be responsible for the full amount of the loss without any backstop by the Federal Government. IXP would also be responsible for any recoupment charges by the Federal Government in the event losses are paid out and its insurance policy is maintained after the payout by the Federal Government. If the Company experiences a loss and IXP is required to pay under its insurance policy, the Company would ultimately record the loss to the extent of the required payment. Therefore, insurance coverage provided by IXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance. In addition, Boston Properties Limited Partnership has issued a guarantee to cover liabilities of IXP in the amount of $20.0 million.
The Company continues to monitor the state of the insurance market in general, and the scope and costs of coverage for acts of terrorism and California earthquake risk in particular, but the Company cannot anticipate what coverage will be available on commercially reasonable terms in future policy years. There are other types of losses, such as from wars, for which the Company cannot obtain insurance at all or at a reasonable cost. With respect to such losses and losses from acts of terrorism, earthquakes or other catastrophic events, if the Company experiences a loss that is uninsured or that exceeds policy limits, the Company could lose the capital invested in the damaged properties, as well as the anticipated future revenues from those properties. Depending on the specific circumstances of each affected property, it is possible that the Company could be liable for mortgage indebtedness or other obligations related to the property. Any such loss could materially and adversely affect the Company’s business and financial condition and results of operations.
Legal Matters 
The Company is subject to various legal proceedings and claims that arise in the ordinary course of business. These matters are generally covered by insurance. Management believes that the final outcome of such matters will not have a material adverse effect on the financial position, results of operations or liquidity of the Company. 
State and Local Tax Matters 
Because Boston Properties, Inc. is organized and qualifies as a REIT, it is generally not subject to federal income taxes, but is subject to certain state and local taxes. In the normal course of business, certain entities through which the Company owns real estate either have undergone, or are currently undergoing, tax audits. Although the Company believes that it has substantial arguments in favor of its positions in the ongoing audits, in some instances there is no controlling precedent or interpretive guidance on the specific point at issue. Collectively, tax deficiency notices received to date from the jurisdictions conducting the ongoing audits have not been material. However, there can be no assurance that future audits will not occur with increased frequency or that the ultimate result of such audits will not have a material adverse effect on the Company’s results of operations. 

158


Environmental Matters 
It is the Company’s policy to retain independent environmental consultants to conduct or update Phase I environmental assessments (which generally do not involve invasive techniques such as soil or ground water sampling) and asbestos surveys in connection with the Company’s acquisition of properties. These pre-purchase environmental assessments have not revealed environmental conditions that the Company believes will have a material adverse effect on its business, assets, financial condition, results of operations or liquidity, and the Company is not otherwise aware of environmental conditions with respect to its properties that the Company believes would have such a material adverse effect. However, from time to time environmental conditions at the Company’s properties have required and may in the future require environmental testing and/or regulatory filings, as well as remedial action.
In February 1999, the Company (through a joint venture) acquired from Exxon Corporation a property in Massachusetts that was formerly used as a petroleum bulk storage and distribution facility and was known by the state regulatory authority to contain soil and groundwater contamination. The Company developed an office park on the property. The Company engaged a specially licensed environmental consultant to oversee the management of contaminated soil and groundwater that was disturbed in the course of construction. Under the property acquisition agreement, Exxon agreed to (1) bear the liability arising from releases or discharges of oil and hazardous substances which occurred at the site prior to the Company’s ownership, (2) continue monitoring and/or remediating such releases and discharges as necessary and appropriate to comply with applicable requirements, and (3) indemnify the Company for certain losses arising from preexisting site conditions. Any indemnity claim may be subject to various defenses, and there can be no assurance that the amounts paid under the indemnity, if any, would be sufficient to cover the liabilities arising from any such releases and discharges.
Environmental investigations at some of the Company’s properties and certain properties owned by affiliates of the Company have identified groundwater contamination migrating from off-site source properties. In each case the Company engaged a licensed environmental consultant to perform the necessary investigations and assessments and to prepare any required submittals to the regulatory authorities. In each case the environmental consultant concluded that the properties qualify under the regulatory program or the regulatory practice for a status which eliminates certain deadlines for conducting response actions at a site. The Company also believes that these properties qualify for liability relief under certain statutory provisions or regulatory practices regarding upgradient releases. Although the Company believes that the current or former owners of the upgradient source properties may bear responsibility for some or all of the costs of addressing the identified groundwater contamination, the Company will take such further response actions (if any) that it deems necessary or advisable. Other than periodic testing at some of these properties, no such additional response actions are anticipated at this time. 
Some of the Company’s properties and certain properties owned by the Company’s affiliates are located in urban, industrial and other previously developed areas where fill or current or historical uses of the areas have caused site contamination. Accordingly, it is sometimes necessary to institute special soil and/or groundwater handling procedures and/or include particular building design features in connection with development, construction and other property operations in order to achieve regulatory closure and/or ensure that contaminated materials are addressed in an appropriate manner. In these situations, it is the Company’s practice to investigate the nature and extent of detected contamination, including potential issues associated with contaminant migration, assess potential liability risks and estimate the costs of required response actions and special handling procedures. The Company then uses this information as part of its decision-making process with respect to the acquisition, deal structure and/or development of the property. For example, the Company owns a parcel in Massachusetts which was formerly used as a quarry/asphalt batching facility. Pre-purchase testing indicated that the site contained relatively low levels of certain contaminants. The Company has developed an office park on this property. Prior to and during redevelopment activities, the Company engaged a specially licensed environmental consultant to monitor environmental conditions at the site and prepare necessary regulatory submittals based on the results of an environmental risk characterization. A submittal has been made to the regulatory authorities in order to achieve regulatory closure at this site. The submittal included an environmental deed restriction that mandates compliance with certain protective measures in a portion of the site where low levels of residual soil contamination have been left in place in accordance with applicable laws.
The Company expects that resolution of the environmental matters relating to the above will not have a material impact on its business, assets, financial condition, results of operations or liquidity. However, the Company cannot assure you that it has identified all environmental liabilities at its properties, that all necessary remediation actions have been or will be undertaken at the Company’s properties or that the Company will be indemnified, in full or at all, in the event that such environmental liabilities arise.

10. Noncontrolling Interests
Noncontrolling interests relate to the interests in Boston Properties Limited Partnership not owned by Boston Properties, Inc. and interests in consolidated property partnerships not wholly-owned by the Company.

Noncontrolling Interest—Common Units
During the years ended December 31, 2019 and 2018, 144,481 and 83,136 OP Units, respectively, were presented by the holders for redemption (including 92,678 and 48,389 OP Units, respectively, issued upon conversion of LTIP Units, 2012 OPP Units, 2013 MYLTIP Units, 2014 MYLTIP Units and 2016 MYLTIP Units) and were redeemed by Boston Properties, Inc. in exchange for an equal number of shares of Common Stock.

After the measurement date, the number of MYLTIP Units, both vested and unvested, that MYLTIP award recipients have earned, if any, based on the establishment of a performance pool, will be entitled to receive distributions in an amount per unit equal to distributions, both regular and special, payable on an OP Unit.
On February 3, 2017, the measurement period for the Company’s 2014 MYLTIP awards ended and, based on Boston Properties, Inc.’s relative TSR performance, the final awards were determined to be 27.7% of target or an aggregate of approximately $3.5 million (after giving effect to employee separations and the unallocated reserve). As a result, an aggregate of 447,386 2014 MYLTIP Units that had been previously granted were automatically forfeited.
On February 4, 2018, the measurement period for the Company’s 2015 MYLTIP awards ended and, based on Boston Properties, Inc.’s relative TSR performance, the final awards were determined to be 22.0% of target or an aggregate of approximately $3.6 million (after giving effect to employee separations). As a result, an aggregate of 337,847 2015 MYLTIP Units that had been previously granted were automatically forfeited.
On February 9, 2019, the measurement period for the Company’s 2016 MYLTIP awards ended and, based on Boston Properties, Inc.’s relative TSR performance, the final awards were determined to be 69.5% of target or an aggregate of approximately $13.6 million (after giving effect to employee separations).

A holder of an OP Unit may present the OP Unit to Boston Properties Limited Partnership for redemption at any time (subject to restrictions agreed upon at the time of issuance of OP Units to particular holders that may restrict such redemption right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, Boston Properties Limited Partnership must redeem the OP Unit for cash equal to the then value of a share of common stock of Boston Properties, Inc. Boston Properties, Inc. may, in its sole discretion, elect to assume and satisfy the redemption obligation by paying either cash or issuing one share of Common Stock. The value of the OP Units (not owned by Boston Properties, Inc. and LTIP Units (including the 2012 OPP Units, 2013 MYLTIP Units, 2014 MYLTIP Units, 2015 MYLTIP Units and 2016 MYLTIP Units) assuming that all conditions had been met for the conversion thereof) had all of such units been redeemed at December 31, 2019 was approximately $2.5 billion based on the last reported price of a share of Common Stock on the New York Stock Exchange of $137.86 per share on December 31, 2019.
Noncontrolling Interests—Property Partnerships
The noncontrolling interests in property partnerships consist of the outside equity interests in ventures that are consolidated with the financial results of the Company because the Company exercises control over the entities that own the properties. The equity interests in these ventures that are not owned by the Company, totaling approximately $1.7 billion at December 31, 2019 and 2018, are included in Noncontrolling Interests—Property Partnerships on the accompanying Consolidated Balance Sheets.
On May 12, 2016, the partners in the Company’s consolidated entity that owns Salesforce Tower located in San Francisco, California amended the venture agreement. Under the original venture agreement, if the Company elected to fund the construction of Salesforce Tower without a construction loan (or a construction loan of less than 50% of project costs) and the venture commenced vertical construction of the project, then the partner’s capital funding obligation would be limited, in which event the Company would fund up to 2.5% of the total project costs (i.e., 50% of the partner’s 5% interest in the venture) in the form of a loan to the partner. This loan would bear interest at the then prevailing market interest rates for construction loans. Under the amended venture agreement, the partners agreed to structure this funding by the Company as preferred equity rather than a loan. The preferred equity contributed by the Company earned a preferred return equal to LIBOR plus 3.00% per annum and was payable to the Company out of any distributions to which the partner would otherwise be entitled until such preferred equity and preferred return was repaid to the Company. The Company contributed an aggregate of approximately $22.6 million of preferred equity to the venture. Also, under the amended venture agreement, (a) from and after the stabilization date, the partner had the right to cause the Company to purchase all (but not less than all) of the partner’s interest and (b) from and after the third anniversary of the stabilization date, the Company had the right to acquire all (but not less than all) of the partner’s interest, in each case, at an agreed upon purchase price or appraised value.  In addition, if certain threshold returns were achieved the partner may be entitled to receive an additional promoted interest with respect to cash flow distributions.  The term stabilization date was defined in the agreement to generally mean the first date after completion upon which Salesforce Tower is (1) at least 90% leased and (2) 50% occupied by tenants that are paying rent. Salesforce Tower is an approximately 1,421,000 net rentable square foot Class A office property.

161


On January 18, 2019, the Company and its partner further amended the venture agreement. Per the amendment, the partner exercised its right to cause the Company to purchase, on April 1, 2019, its 5% ownership interest and promoted profits interest in the venture for cash totaling approximately $210.9 million, which amount was reduced by approximately $24.1 million, consisting of the repayment of the Company’s preferred equity and preferred return as provided for in the amended venture agreement.
On April 1, 2019, the Company completed the acquisition of its partner’s 5% ownership interest and promoted profits interest in the consolidated entity for cash totaling approximately $210.9 million, which amount was reduced by approximately $24.1 million to $186.8 million to reflect the repayment of the Company’s preferred equity and preferred return in the venture, as described above. The Company now owns 100% of Salesforce Tower. The Company has accounted for the transaction as an equity transaction for financial reporting purposes and has reflected the difference between the fair value of the total consideration paid and the related carrying value of the noncontrolling interest - property partnership totaling approximately $162.5 million as a decrease to Additional Paid-in Capital and Partners’ Capital in the Consolidated Balance Sheets of Boston Properties, Inc. and Boston Properties Limited Partnership, respectively.
On June 6, 2017, in conjunction with the refinancing of the indebtedness of the Company’s consolidated entity in which it has a 60% interest and that owns 767 Fifth Avenue (the General Motors Building) located in New York City, the members of the consolidated entity amended the limited liability company agreement to provide for the contribution of the remaining unpaid principal balance of the members’ notes payable totaling approximately $273.9 million (of which the Company’s share of approximately $164.4 million is eliminated in consolidation) to equity in the consolidated entity, resulting in an increase of approximately $109.6 million to Noncontrolling Interests in Property Partnerships on the Company’s Consolidated Balance Sheets. There were no changes to the ownership interests or rights of the members as a result of the amendment.
11. Stockholders’ Equity / Partners’ Capital

Net operating income (“NOI”) is a non-GAAP financial measure equal to net income attributable to Boston Properties, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership common unitholders, as applicable, the most directly comparable GAAP financial measures, plus (1) preferred dividends/distributions, net income attributable to noncontrolling interests, interest expense, losses (gains) from early extinguishments of debt, impairment losses, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts and corporate general and administrative expense less (2) gains (losses) from investments in securities, interest and other income, gains on sales of real estate, income from unconsolidated joint ventures, direct reimbursements of payroll and related costs from management services contracts and development and management services revenue. The Company believes NOI is useful to investors as a performance measure and believes it provides useful information to investors regarding its results of operations and financial condition because, when compared across periods, it reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspective not immediately apparent from net income attributable to Boston Properties, Inc. common shareholders and net income attributable to Boston Properties Limited Partnership common unitholders. For example, interest expense is not necessarily linked to the operating performance of a real estate asset and is often incurred at the corporate level as opposed to the property level. Similarly, interest expense may be incurred at the property level even though the financing proceeds may be used at the corporate level (e.g., used for other investment activity). In addition, depreciation and amortization expense, because of historical cost accounting and useful life estimates, may distort operating performance measures at the property level. NOI presented by the Company may not be comparable to NOI reported by other REITs or real estate companies that define NOI differently.

166


Asset information by segment is not reported because the Company does not use this measure to assess performance. Therefore, depreciation and amortization expense is not allocated among segments. Preferred dividends/distributions, interest expense, losses (gains) from early extinguishments of debt, impairment losses, depreciation and amortization expense, transaction costs, payroll and related costs from management services contracts, corporate general and administrative expense, gains (losses) from investments in securities, interest and other income, gains on sales of real estate, direct reimbursements of payroll and related costs from management services contracts and development and management services revenue are not included in NOI and are provided as reconciling items to the Company’s reconciliations of its share of NOI to net income attributable to common shareholders/unitholders.
The Company’s segments are based on the Company’s method of internal reporting which classifies its operations by geographic area. The Company’s segments by geographic area are Boston, Los Angeles, New York, San Francisco and Washington, DC. The Company also presents information for each segment by property type, including Office, Residential and Hotel.
Beginning in 2019, the Company modified the presentation of its geographic area classification for all periods presented to include the Los Angeles geographic area to align with its method of internal reporting. The Company expanded its presence in the Los Angeles geographic area with its equity method investment in Santa Monica Business Park located in Santa Monica, California. As of December 31, 2019, the Company has equity interests in a portfolio of 27 office and retail properties in the Los Angeles geographic area aggregating approximately 2.3 million net rentable square feet, all of which are owned through investments in unconsolidated joint ventures. The Company began presenting the Los Angeles geographic area as a reportable segment to align with its method of internal reporting given the increased significance as a result of commencing a full reporting period of ownership of the Santa Monica Business Park portfolio. The inclusion of the Los Angeles geographic area has also resulted in a change in the reported measure of segment profit or loss from NOI to the Company’s share of NOI. This change has been reflected in all periods presented and the impact of the change can been seen within the tables below. The Company has not presented rental revenue and rental expenses for properties owned through investments in unconsolidated joint ventures, including those in the Los Angeles geographic area, as the Company accounts for these properties using the equity method of accounting.

14. Earnings Per Share / Common Unit
Boston Properties, Inc.
The following table provides a reconciliation of both the net income attributable to Boston Properties, Inc. common shareholders and the number of common shares used in the computation of basic earnings per share (“EPS”), which is calculated by dividing net income attributable to Boston Properties, Inc. common shareholders by the weighted-average number of common shares outstanding during the period. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are also participating securities. As such, unvested restricted common stock of Boston Properties, Inc. and Boston Properties Limited Partnership’s LTIP Units, 2012 OPP Units and MYLTIP Units are considered participating securities. Participating securities are included in the computation of basic EPS of Boston Properties, Inc. using the two-class method. Participating securities are included in the computation of diluted EPS of Boston Properties, Inc. using the if-converted method if the impact is dilutive. Because the 2012 OPP Units, 2013 MYLTIP Units, 2014 MYLTIP Units, 2015 MYLTIP Units and 2016 MYLTIP Units required, and the 2017-2019 MYLTIP Units require, Boston Properties, Inc. to outperform absolute and relative return thresholds, unless such thresholds have been met by the end of the applicable reporting period, Boston Properties, Inc. excludes such units from the diluted EPS calculation. Other potentially dilutive common shares, including stock options, restricted stock and other securities of Boston Properties Limited Partnership that are exchangeable for Boston Properties, Inc.’s Common Stock, and the related impact on earnings, are considered when calculating diluted EPS.

Boston Properties Limited Partnership
The following table provides a reconciliation of both the net income attributable to Boston Properties Limited Partnership common unitholders and the number of common units used in the computation of basic earnings per common unit, which is calculated by dividing net income attributable to Boston Properties Limited Partnership common unitholders by the weighted-average number of common units outstanding during the period. Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are also participating securities. As such, unvested restricted common stock of Boston Properties, Inc. and Boston Properties Limited Partnership’s LTIP Units, 2012 OPP Units and MYLTIP Units are considered participating securities. Participating securities are included in the computation of basic earnings per common unit using the two-class method. Participating securities are included in the computation of diluted earnings per common unit using the if-converted method if the impact is dilutive. Because the 2012 OPP Units, 2013 MYLTIP Units, 2014 MYLTIP Units, 2015 MYLTIP Units and 2016 MYLTIP Units required, and the 2017-2019 MYLTIP Units require, Boston Properties, Inc. to outperform absolute and relative return thresholds, unless such thresholds have been met by the end of the applicable reporting period, Boston Properties Limited Partnership excludes such units from the diluted earnings per common unit calculation. Other potentially dilutive common units and the related impact on earnings are considered when calculating diluted earnings per common unit. Included in the number of units (the denominator) below are approximately 17,618,000, 17,485,000 and 17,471,000 redeemable common units for the years ended December 31, 2019, 2018 and 2017, respectively.

15. Employee Benefit Plans
Effective January 1, 1985, the predecessor of the Company adopted a 401(k) Savings Plan (the “Plan”) for its employees. Upon formation, the Company adopted the Plan and the terms of the Plan. 
Under the Plan, as amended, the Company’s matching contribution equals 200% of the first 3% of participant’s eligible earnings contributed (utilizing earnings that are not in excess of an amount established by the IRS ($280,000, $275,000 and $270,000 in 2019, 2018 and 2017, respectively), indexed for inflation) with no vesting requirement. The Company’s aggregate matching contribution for the years ended December 31, 2019, 2018 and 2017 was approximately $4.2 million, $4.1 million and $4.1 million, respectively. 
The Company also maintains a deferred compensation plan that is designed to allow officers of Boston Properties, Inc. to defer a portion of the officer’s current income on a pre-tax basis and receive a tax-deferred return on these deferrals based on the performance of specific investments selected by the officer. The Company’s obligation under the plan is that of an unsecured promise to pay the deferred compensation to the plan participants in the future. At December 31, 2019 and 2018, the Company had maintained approximately $36.0 million and $28.2 million, respectively, in a separate account, which is not restricted as to its use. The Company’s liability under the plan is equal to the total amount of compensation deferred by the plan participants and earnings on the deferred compensation pursuant to investments elected by the plan participants. The Company’s liability as of December 31, 2019 and 2018 was approximately $36.0 million and $28.2 million, respectively, which are included in the accompanying Consolidated Balance Sheets.
16. Stock Option and Incentive Plan
At Boston Properties, Inc.’s 2012 annual meeting of stockholders held on May 15, 2012, its stockholders approved the Boston Properties, Inc. 2012 Stock Option and Incentive Plan (the “2012 Plan”). The 2012 Plan replaced the 1997 Stock Option and Incentive Plan (the “1997 Plan”). The material terms of the 2012 Plan include, among other things: (1) the maximum number of shares of common stock reserved and available for issuance under the 2012 Plan is the sum of (i) 13,000,000 newly authorized shares, plus (ii) the number of shares available for grant under the 1997 Stock Plan immediately prior to the effective date of the 2012 Plan, plus (iii) any shares underlying grants under the 1997 Plan that are forfeited, canceled or terminated (other than by exercise) in the future; (2) “full-value” awards (i.e., awards other than stock options) are multiplied by a 2.32 conversion ratio to calculate the number of shares available under the 2012 Plan that are used for each full-value award, as opposed to a 1.0 conversion ratio for each stock option awarded under the 2012 Plan; (3) shares tendered or held back for taxes will not be added back to the reserved pool under the 2012 Plan; (4) stock options may not be re-priced without stockholder approval; and (5) the term of the 2012 Plan is for 10 years from the date of stockholder approval.
On February 5, 2019, Boston Properties, Inc.’s Compensation Committee approved the 2019 MYLTIP awards under the 2012 Plan to certain officers and employees of Boston Properties, Inc. The 2019 MYLTIP awards utilize Boston Properties, Inc.’s TSR over a three-year measurement period, on an annualized, compounded basis, as the performance metric. Earned awards will be based on Boston Properties, Inc.’s TSR relative to the Nareit Office Index, adjusted to include Vornado Realty Trust. Earned awards will range from zero to a maximum of 220,734

173


LTIP Units depending on Boston Properties, Inc.’s TSR relative to the Nareit Office Index, adjusted to include Vornado Realty Trust, with a target of approximately 110,367 LTIP Units and linear interpolation between zero and maximum. Earned awards (if any) will vest 50% on February 4, 2022 and 50% on February 4, 2023, based on continued employment. Vesting will be accelerated in the event of a change in control, termination of employment by Boston Properties, Inc. without cause, or termination of employment by the award recipient for good reason, death, disability or retirement. If there is a change of control prior to February 4, 2022, earned awards will be calculated based on TSR performance up to the date of the change of control. The 2019 MYLTIP awards are in the form of LTIP Units issued on the grant date which (i) are subject to forfeiture to the extent awards are not earned and (ii) prior to the performance measurement date are only entitled to one-tenth (10%) of the regular quarterly distributions payable on common partnership units. Under ASC 718 “Compensation - Stock Compensation”, the 2019 MYLTIP awards have an aggregate value of approximately $13.5 million, which amount will generally be amortized into earnings over the four year plan period under the graded vesting method.
On February 9, 2019, the measurement period for the Company’s 2016 MYLTIP awards ended and, based on Boston Properties, Inc.’s relative TSR performance, the final awards were determined to be 69.5% of target or an aggregate of approximately $13.6 million (after giving effect to employee separations). As a result, an aggregate of 364,980 2016 MYLTIP Units that had been previously granted were automatically forfeited.
On February 4, 2018, the measurement period for the Company’s 2015 MYLTIP awards ended and, based on Boston Properties, Inc.’s relative TSR performance, the final awards were determined to be 22.0% of target or an aggregate of approximately $3.6 million (after giving effect to employee separations). As a result, an aggregate of 337,847 2015 MYLTIP Units that had been previously granted were automatically forfeited.
On February 3, 2017, the measurement period for the Company’s 2014 MYLTIP awards ended and, based on Boston Properties, Inc.’s relative TSR performance, the final awards were determined to be 27.7% of target or an aggregate of approximately $3.5 million (after giving effect to employee separations and the unallocated reserve). As a result, an aggregate of 447,386 2014 MYLTIP Units that had been previously granted were automatically forfeited.
Boston Properties, Inc. issued 26,503, 20,320 and 37,414 shares of restricted common stock and Boston Properties Limited Partnership issued 181,919, 205,838 and 113,918 LTIP Units to employees and non-employee directors under the 2012 Plan during the years ended December 31, 2019, 2018 and 2017, respectively. Boston Properties, Inc. did not issue any non-qualified stock options under the 2012 Plan during the years ended December 31, 2019, 2018 and 2017. Boston Properties Limited Partnership issued 220,734 2019 MYLTIP Units, 342,659 2018 MYLTIP Units and 400,000 2017 MYLTIP Units to employees under the 2012 Plan during the years ended December 31, 2019, 2018 and 2017, respectively. Employees and non-employee directors paid $0.01 per share of restricted common stock and $0.25 per LTIP Unit, OPP Unit and MYLTIP Unit. When issued, LTIP Units are not economically equivalent in value to a share of Common Stock, but over time can increase in value to one-for-one parity with Common Stock if there is sufficient appreciation in the value of the Company’s assets. The aggregate value of the LTIP Units is included in noncontrolling interests in the Consolidated Balance Sheets. Grants of restricted stock and LTIP Units to employees vest in four equal annual installments. Restricted stock is measured at fair value on the date of grant based on the number of shares granted and the closing price of Boston Properties, Inc.’s Common Stock on the date of grant as quoted on the New York Stock Exchange. Such value is recognized as an expense ratably over the corresponding employee service period. Non-qualified stock options, which are valued using the Black-Scholes option-pricing model, are recognized as an expense ratably over the corresponding employee service period. As the 2012 OPP Awards, 2013 MYLTIP Awards, 2014 MYLTIP Awards, 2015 MYLTIP Awards, 2016 MYLTIP Awards, 2017 MYLTIP Awards, 2018 MYLTIP Awards and 2019 MYLTIP Awards are subject to both a service condition and a market condition, the Company recognizes the compensation expense related to the 2012 OPP Awards, 2013 MYLTIP Awards, 2014 MYLTIP Awards, 2015 MYLTIP Awards 2016 MYLTIP Awards, 2017 MYLTIP Awards, 2018 MYLTIP Awards and 2019 MYLTIP Awards under the graded vesting attribution method. Under the graded vesting attribution method, each portion of the award that vests at a different date is accounted for as a separate award and recognized over the period appropriate to that portion so that the compensation cost for each portion should be recognized in full by the time that portion vests. The Company recognizes forfeitures as they occur on its awards of stock-based compensation. Dividends paid on both vested and unvested shares of restricted stock are charged directly to Dividends in Excess of Earnings in Boston Properties, Inc.’s Consolidated Balance Sheets and Partners’ Capital in Boston Properties Limited Partnership’s Consolidated Balance Sheets. Aggregate stock-based compensation expense associated with restricted stock, non-qualified stock options, LTIP Units, 2013 MYLTIP Units, 2014 MYLTIP Units, 2015 MYLTIP Units, 2016 MYLTIP Units, 2017 MYLTIP Units, 2018 MYLTIP Units and 2019 MYLTIP Units was approximately $39.8 million, $38.0 million and $33.2 million for the years ended December 31, 2019, 2018 and 2017, respectively. At December 31,

174


2019, there was (1) an aggregate of approximately $23.3 million of unrecognized compensation expense related to unvested restricted stock and LTIP Units and (2) an aggregate of approximately $12.4 million of unrecognized compensation expense related to unvested 2017 MYLTIP Units, 2018 MYLTIP Units and 2019 MYLTIP Units that is expected to be recognized over a weighted-average period of approximately 2.4 years.
The shares of restricted stock were valued at approximately $3.5 million ($131.27 per share weighted-average), $2.4 million ($119.27 per share weighted-average) and $4.9 million ($130.32 per share weighted-average) for the years ended December 31, 2019, 2018 and 2017, respectively. 
LTIP Units were valued using a Monte Carlo simulation method model in accordance with the provisions of ASC 718. LTIP Units issued during the years ended December 31, 2019, 2018 and 2017 were valued at approximately $22.1 million, $22.7 million and $13.6 million, respectively. The weighted-average per unit fair value of LTIP Unit grants in 2019, 2018 and 2017 was $121.50, $110.29 and $119.41, respectively. The per unit fair value of each LTIP Unit granted in 2019, 2018 and 2017 was estimated on the date of grant using the following assumptions; an expected life of 5.7 years, 5.7 years and 5.7 years, a risk-free interest rate of 2.68%, 2.63% and 2.14% and an expected price volatility of 27.0%, 27.0% and 28.0%, respectively. 
There were no non-qualified stock options granted during the years ended December 31, 2019, 2018 and 2017.

The total intrinsic value of the outstanding and exercisable stock options as of December 31, 2019 was approximately $16.4 million. In addition, Boston Properties, Inc. had 540,441 options exercisable at a weighted-average exercise price of $96.35 at December 31, 2018 and 2017. 
Boston Properties, Inc. adopted the 1999 Non-Qualified Employee Stock Purchase Plan (the “Stock Purchase Plan”) to encourage the ownership of Common Stock by eligible employees. The Stock Purchase Plan became effective on January 1, 1999 with an aggregate maximum of 250,000 shares of Common Stock available for issuance. The Stock Purchase Plan provides for eligible employees to purchase on the business day immediately following the end of the biannual purchase periods (i.e., January 1-June 30 and July 1-December 31) shares of Common Stock at a purchase price equal to 85% of the average closing prices of the Common Stock during the last ten business days of the purchase period. Boston Properties, Inc. issued 5,862, 6,268 and 6,317 shares with the weighted-average purchase price equal to $104.11 per share, $107.20 per share and $105.97 per share under the Stock Purchase Plan during the years ended December 31, 2019, 2018 and 2017, respectively.
17. Related Party Transactions  
A firm controlled by Mr. Raymond A. Ritchey’s brother was paid aggregate leasing commissions of approximately $21,000, $921,000 and $368,000 for the years ended December 31, 2019, 2018 and 2017, respectively, related to certain exclusive leasing arrangements for certain Northern Virginia properties. Mr. Ritchey is a Senior Executive Vice President of Boston Properties, Inc.
In accordance with Boston Properties, Inc.’s 2012 Plan, and as approved by its Board of Directors, seven non-employee directors made elections to receive deferred stock units in lieu of cash fees for 2019. As a result of these elections, the aggregate cash fees otherwise payable to a non-employee director during a fiscal quarter are converted into a number of deferred stock units equal to the aggregate cash fees divided by the last reported sales price of a share of Boston Properties, Inc.’s Common Stock on the last trading of the applicable fiscal quarter. The deferred stock units are also credited with dividend equivalents as dividends are paid by Boston Properties, Inc. The deferred stock units may be settled in shares of Common Stock upon the cessation of such director’s service on the Board of Directors of Boston Properties, Inc. The Company modified the terms of the non-employee director compensation program to provide, subject to certain conditions, the non-employee directors holding deferred stock units with the ability to elect, following cessation of their service on the Company’s Board of Directors, to diversify their investment elections into non-employer securities on a pre-tax basis and receive tax-deferred returns on such deferrals, which will ultimately be settled in cash. The Company’s obligation under the plan is that of an unsecured promise to pay the deferred compensation to the non-employee director in the future. At December 31, 2019, the Company had maintained approximately $0.7 million in a separate account, which is not restricted as to its use. The Company’s liability under the plan is equal to the total amount of compensation deferred by the non-employee director and earnings on the deferred compensation pursuant to investments elected by the non-employee director. The Company’s liability as of December 31, 2019 was approximately $0.7 million, which is included in the accompanying Consolidated Balance Sheets. The modification of the terms of the non-employee director compensation program required a change to the classification of these deferred stock units from permanent equity to temporary equity on the Consolidated Balance Sheets of Boston Properties, Inc. and Boston Properties Limited Partnership within Redeemable Deferred Stock Units (See Note 2). On May 21, 2019, in connection with the cessation of a director’s service on the Board of Directors of Boston Properties, Inc., Boston Properties, Inc. issued 17,949 shares of Common Stock in settlement of a portion of the director’s outstanding deferred stock units. In addition, on September 3, 2019, the Company converted 4,917 of such director’s deferred stock units as a result of such director’s election to diversify their investment elections into non-employer securities. On May 23, 2018, in connection with the cessation of a director’s service on the Board of Directors of Boston Properties, Inc., Boston Properties, Inc. issued 36,836 shares of Common Stock in settlement of the director’s outstanding deferred stock units. At December 31, 2019 and 2018, Boston Properties, Inc. had outstanding 60,676 and 74,966 deferred stock units, respectively.

On January 28, 2020, a joint venture in which the Company has a 55% interest commenced development of the first phase of its Platform 16 project located in San Jose, California. The first phase of the Platform 16 development project consists of an approximately 390,000 net rentable square foot Class A office building and a below-grade parking garage. On February 20, 2020, the joint venture acquired the land under the ground lease for a purchase price totaling approximately $134.8 million. The joint venture had previously made a deposit totaling $15.0 million, which deposit was credited against the purchase price. Platform 16 consists of a parcel of land totaling approximately 5.6 acres that will support the development of approximately 1.1 million square feet of commercial office space (See Notes 3 and 5).
On January 28, 2020, the Company exercised its option to acquire real property at 425 Fourth Street located in San Francisco, California for a purchase price totaling approximately $134.1 million. 425 Fourth Street will support the development of approximately 804,000 square feet of primarily commercial office space. The Company expects to complete the acquisition during the second quarter of 2020.
On January 31, 2020 and February 4, 2020, Boston Properties, Inc. issued an aggregate of 24,503 shares of restricted Common Stock and Boston Properties Limited Partnership issued an aggregate of 196,927 LTIP Units under the 2012 Plan to certain employees of Boston Properties, Inc.

Earned awards will range from zero to a maximum of 203,278 LTIP Units depending on Boston Properties, Inc.’s TSR relative to the FTSE Nareit Office Index, adjusted to include Vornado Realty Trust, with a target of approximately 101,638 LTIP Units and linear interpolation between zero and maximum. Under ASC 718, the 2020 MYLTIP awards have an aggregate value of approximately $13.7 million.
On February 6, 2020, the measurement period for the Company’s 2017 MYLTIP awards ended and, based on Boston Properties, Inc.’s relative TSR performance, the final awards were determined to be 83.8% of target or an aggregate of approximately $17.6 million (after giving effect to employee separations). As a result, an aggregate of 270,942 2017 MYLTIP Units that had been previously granted were automatically forfeited.
