BOSTON PROPERTIES, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

1. Organization

Boston Properties, Inc. (the “Company”), a Delaware corporation, is a self-administered and self-managed real estate investment trust (“REIT”). The Company is the sole general partner of Boston Properties Limited Partnership (the “Operating Partnership”) and at September 30, 2014 owned an approximate 89.5% (89.2% at September 30, 2013) general and limited partnership interest in the Operating Partnership. Partnership interests in the Operating Partnership are denominated as “common units of partnership interest” (also referred to as “OP Units”), “long term incentive units of partnership interest” (also referred to as “LTIP Units”) or “preferred units of partnership interest” (also referred to as “Preferred Units”). In addition, in February 2011 and February 2012, the Company issued LTIP Units in connection with the granting to employees of outperformance awards (also referred to as “2011 OPP Units” and “2012 OPP Units,” respectively, and collectively as “OPP Units”). On January 31, 2014, the measurement period for the Company’s 2011 OPP Unit awards expired and the Company’s total return to shareholders (“TRS”) was not sufficient for employees to earn and therefore become eligible to vest in any of the 2011 OPP Unit awards. Accordingly, all 2011 OPP Unit awards were automatically forfeited (See Notes 8 and 11). In February 2013 and February 2014, the Company issued LTIP Units in connection with the granting to employees of multi-year, long-term incentive program (“MYLTIP”) awards (also referred to as “2013 MYLTIP Units” and “2014 MYLTIP Units,” respectively, and collectively as “MYLTIP Units”). Because the rights, preferences and privileges of OPP Units and MYLTIP Units differ from other LTIP Units granted to employees as part of the annual compensation process, unless specifically noted otherwise, all references to LTIP Units exclude OPP Units and MYLTIP Units (See Notes 8 and 11).

Unless specifically noted otherwise, all references to OP Units exclude units held by the Company. A holder of an OP Unit may present such OP Unit to the Operating 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, the Operating Partnership is obligated to redeem such OP Unit for cash equal to the value of a share of common stock of the Company (“Common Stock”) at such time. In lieu of a cash redemption, the Company may elect to acquire such 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 the Company 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. An LTIP Unit is generally the economic equivalent of a share of restricted common stock of the Company. LTIP 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 Note 9).

At September 30, 2014, there were two series of Preferred Units outstanding (i.e., Series Four Preferred Units and Series B Preferred Units).

•

The Series Four Preferred Units are not convertible into or exchangeable for any security of the Operating Partnership or the Company, have a per unit liquidation preference of $50.00 and are entitled to receive quarterly distributions of $0.25 per unit (or an annual rate of 2.00%) (See Notes 8 and 13).

•

The Series B Preferred Units were issued to the Company on March 27, 2013 in connection with the Company’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”). The Company contributed the net proceeds from the offering to the Operating 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 9).

All references herein to the Company refer to Boston Properties, Inc. and its consolidated subsidiaries, including the Operating Partnership, collectively, unless the context otherwise requires.

Properties

At September 30, 2014, the Company owned or had interests in a portfolio of 172 commercial real estate properties (the “Properties”) aggregating approximately 46.4 million net rentable square feet, including ten properties under construction totaling approximately 3.3 million net rentable square feet. In addition, the Company has structured parking for approximately 45,835 vehicles containing approximately 15.7 million square feet. At September 30, 2014, the Properties consist of:

•

163 office properties, including 132 Class A office properties (including nine properties under construction) and 31 Office/Technical properties;

•

one hotel;

•

five retail properties (including one property under construction); and

•

three residential properties.

The Company owns or controls undeveloped land parcels totaling approximately 492.1 acres.

The Company considers Class A office properties to be centrally 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. The Company considers Office/Technical properties to be properties that support office, research and development, laboratory and other technical uses. The Company’s definitions of Class A Office and Office/Technical properties may be different than those used by other companies.

2. Basis of Presentation and Summary of Significant Accounting Policies

Boston Properties, Inc. does not have any other significant assets, liabilities or operations, other than its investment in the Operating Partnership, nor does it have employees of its own. The Operating 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 (“VIE”s) 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.

The accompanying interim financial statements are unaudited; however, the financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and in conjunction with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the disclosures required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting solely of normal recurring matters) necessary for a fair statement of the financial statements for these interim periods have been included. The results of operations for the interim periods are not necessarily indicative of the results to be obtained for other interim periods or for the full fiscal year. The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosure required by accounting principles generally accepted in the United States of America. These financial statements should be read in conjunction with the Company’s financial statements and notes thereto contained in the Company’s Annual Report in the Company’s Form 10-K for its fiscal year ended December 31, 2013. Certain prior year amounts have been reclassified to conform to the current year presentation. Beginning on January 1, 2014, the properties that were historically part of the Company’s Princeton region are reflected as the suburban component of the Company’s New York region (See Note 12).

The Company follows the authoritative guidance for fair value measurements when valuing its financial instruments for disclosure purposes. The Company determines the fair value of its unsecured senior notes and

unsecured exchangeable senior notes using market prices. The inputs used in determining the fair value of the Company’s unsecured senior notes and unsecured exchangeable senior notes are categorized at a level 1 basis (as defined in the accounting standards for Fair Value Measurements and Disclosures) due to the fact that the Company 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 the accounting standards for Fair Value Measurements and Disclosures) if trading volumes are low. The Company determines the fair value of its mortgage notes payable using discounted cash flow analyses by discounting the spread between the future contractual interest payments and hypothetical future interest payments on 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 mortgage notes payable and mezzanine notes payable are categorized at a level 3 basis (as defined in the accounting standards for Fair Value Measurements and Disclosures) due to the fact that the Company considers the rates used in the valuation techniques to be unobservable inputs.

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. The following table presents the aggregate carrying value of the Company’s indebtedness and the Company’s corresponding estimate of fair value as of September 30, 2014 and December 31, 2013 (in thousands):


	September 30, 2014				December 31, 2013
	Carrying Amount		Estimated Fair Value		Carrying Amount			Estimated Fair Value
Mortgage notes payable	$	4,328,464	$	4,460,353	$	4,449,734		$	4,545,283
Mezzanine notes payable		310,114		310,141		311,040			311,064
Unsecured senior notes		5,837,172		6,173,499		5,835,854			6,050,517
Unsecured exchangeable senior notes		—		—		744,880	(1)		750,266

Total	$	10,475,750	$	10,943,993	$	11,341,508		$	11,657,130

(1)	Includes the net adjustment for the equity component allocation totaling approximately $2.4 million at December 31, 2013.

Out-of-Period Adjustment

During the nine months ended September 30, 2014, the Company recorded an allocation of net income to the noncontrolling interest holder in its Fountain Square consolidated joint venture totaling approximately $1.9 million related to the cumulative non-cash adjustment to the accretion of the changes in the redemption value of the noncontrolling interest. This resulted in the overstatement of Noncontrolling Interests in Property Partnerships by approximately $1.9 million during the nine months ended September 30, 2014 and an understatement of Noncontrolling Interests in Property Partnerships in the aggregate amount of approximately $1.9 million in previous periods prior to 2014. Because this adjustment was not material to the prior periods’ consolidated financial statements and the impact of recording the adjustment in 2014 was not material to the Company’s consolidated financial statements, the Company recorded the related adjustment during the nine months ended September 30, 2014. The out of period adjustment was identified and recorded during the second quarter of 2014.

Recent Accounting Pronouncements

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). ASU No. 2014-08 is effective prospectively for reporting periods beginning after December 15, 2014. Early adoption is permitted, and the Company early adopted ASU No. 2014-08 during the first quarter of 2014. The Company’s adoption of ASU No. 2014-08 did not have a material impact on its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contract with Customers (Topic 606)” (“ASU 2014-09”). The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying ASU 2014-09, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB’s Accounting Standards Codification (“ASC”). ASU 2014-09 is effective for annual reporting periods (including interim periods within that reporting period) beginning after December 15, 2016 and shall be applied using either a full retrospective or modified retrospective approach. Early adoption is not permitted. The Company is currently assessing the potential impact that the adoption of ASU 2014-09 will have on its consolidated financial statements.

In June 2014, the FASB issued ASU No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (“ASU 2014-12”). The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in ASC Topic No. 718, “Compensation—Stock Compensation” (“ASC 718”), as it relates to awards with performance conditions that affect vesting to account for such awards. The amendments in ASU 2014-12 are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in ASU 2014-12 either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The Company does not expect the adoption of ASU 2014-12 to have a material impact on its consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements—Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”). ASU 2014-15 requires an entity to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the financial statements are available to be issued when applicable) and to provide related footnote disclosures in certain circumstances. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter with early adoption permitted. The Company does not expect the adoption of ASU 2014-15 to have a material impact on its consolidated financial statements.

Dispositions

On June 11, 2014, the Company entered into a contract for the sale of its Patriots Park properties located in Reston, Virginia for a sale price of $321.0 million, which exceeds the carrying value at September 30, 2014.

Mountain View Technology Park is a seven-building complex of Office/Technical properties aggregating approximately 135,000 net rentable square feet. Mountain View Research Park Building Sixteen is an Office/Technical property with approximately 63,000 net rentable square feet.

On August 20, 2014, a portion of the land parcel at the Company’s One Reston Overlook property located in Reston, Virginia was taken by eminent domain. Net cash proceeds totaled approximately $2.6 million, resulting in a gain on sale of real estate totaling approximately $1.2 million.

On August 22, 2014, the Company completed the sale of a parcel of land within its Broad Run Business Park property located in Loudoun County, Virginia for a sale price of approximately $9.8 million. Net cash proceeds totaled approximately $9.7 million, resulting in a gain on sale of real estate totaling approximately $4.3 million. The parcel is an approximately 15.5 acre land parcel subject to a ground lease that was scheduled to expire on October 31, 2048 with a tenant that exercised its purchase option under the ground lease.

On September 16, 2014, the Company entered into a binding purchase and sale agreement to sell a 45% interest in each of 601 Lexington Avenue in New York City and Atlantic Wharf Office Building and 100 Federal Street in Boston for an aggregate gross sales price of approximately $1.827 billion in cash, less the partner’s pro rata share of the indebtedness secured by 601 Lexington Avenue, subject to certain prorations and adjustments. In connection with the sale, the Company will form a joint venture for each property with the buyer and provide

customary property management and leasing services to the joint ventures. 601 Lexington Avenue is a 1,669,000 square foot Class A office complex located in Midtown Manhattan. The property consists of a 59-story tower as well as a six-story low-rise office and retail building. The property is subject to existing mortgage indebtedness of approximately $712.9 million. The Atlantic Wharf Office Building is a 791,000 square foot Class A office tower located on Boston’s Waterfront. 100 Federal Street is a 1,323,000 square foot Class A office tower located in Boston’s Financial District. The transaction will not qualify as a sale of real estate for financial reporting purposes as the Company will continue to control the joint ventures and will therefore continue to account for the properties on a consolidated basis in its financial statements (See Note 13).

The Company did not have any dispositions during the three and nine months ended September 30, 2014 that qualified for discontinued operations presentation.

Certain of the Company’s unconsolidated joint venture agreements include provisions whereby, at certain specified times, each partner has the right to initiate a purchase or sale of its interest in the joint ventures at an agreed upon fair value. Under these provisions, the Company is not compelled to purchase the interest of its outside joint venture partners.

The combined summarized balance sheets of the Company’s unconsolidated joint ventures are as follows:

This amount represents the aggregate difference between the Company’s historical cost basis and the basis reflected at the joint venture level, which is typically amortized over the life of the related assets and liabilities. Basis differentials occur from impairment of investments and upon the transfer of assets that were previously owned by the Company into a joint venture. In addition, certain acquisition, transaction and other costs may not be reflected in the net assets at the joint venture level.

On April 10, 2014, the Company entered into a joint venture with an unrelated third party to acquire a parcel of land located at 501 K Street in Washington, DC. The Company anticipates the land parcel will accommodate an approximate 520,000 square foot Class A office property to be developed in the future. The joint venture partner contributed the land for a 50% interest in the joint venture and the Company contributed cash of approximately $39.0 million for its 50% interest. Under the joint venture agreement, the partner will be entitled to up to two additional payments from the venture based on increases in total square footage of the project above 520,000 square feet and achieving certain project returns at stabilization.

On April 30, 2014, the Company’s partner in its Annapolis Junction joint venture contributed a parcel of land and improvements and the Company contributed cash of approximately $5.4 million to the joint venture. The Company has a 50% interest in this joint venture. The joint venture has commenced construction of Annapolis Junction Building Eight, which when completed will consist of a Class A office property with

approximately 125,000 net rentable square feet located in Annapolis, Maryland. In addition, on June 23, 2014, the joint venture obtained construction financing collateralized by the development project totaling $26.0 million. The construction financing bears interest at a variable rate equal to LIBOR plus 1.50% per annum and matures on June 23, 2017, with two, one-year extension options, subject to certain conditions.

5. Mortgage Notes Payable

On July 1, 2014, the Company used available cash to repay the mortgage loan collateralized by its New Dominion Technology Park Building Two property located in Herndon, Virginia totaling $63.0 million.

6. Unsecured Exchangeable Senior Notes

On February 18, 2014, the Company’s Operating Partnership repaid at maturity the $747.5 million aggregate principal amount of its 3.625% exchangeable senior notes due 2014 plus accrued and unpaid interest thereon.

In addition, in the normal course of business, the Company guarantees to certain tenants the obligations of its subsidiaries for the payment of tenant improvement allowances and brokerage commissions in connection with their leases and limited costs arising from delays in delivery of their premises.

The Company has letter of credit and performance obligations of approximately $19.1 million related to lender and development requirements.

Certain of the Company’s joint venture agreements include provisions whereby, at certain specified times, each partner has the right to initiate a purchase or sale of its interest in the joint ventures. With limited exception, under these provisions, the Company is not compelled to purchase the interest of its outside joint venture partners (See also Note 8). Under certain of the Company’s joint venture agreements, if certain return thresholds are achieved the partners will be entitled to an additional promoted interest or payments.

In connection with the assumption of 767 Fifth Avenue’s (the General Motors Building) secured loan by the Company’s consolidated joint venture, 767 Venture, LLC, the Company guaranteed the consolidated joint venture’s obligation to fund various escrows, including tenant improvements, taxes and insurance in lieu of cash deposits. As of September 30, 2014, the maximum funding obligation under the guarantee was approximately $14.8 million. The Company earns a fee from the joint venture for providing the guarantee and has an agreement with the outside partners to reimburse the joint venture for their share of any payments made under the guarantee.

In connection with the mortgage financing collateralized by the Company’s John Hancock Tower property located in Boston, Massachusetts, the Company has agreed to guarantee approximately $28.8 million related to its obligations to provide funds for certain tenant re-leasing costs. The mortgage financing matures on January 6, 2017.

From time to time, the Company (or the applicable joint venture) has also agreed to guarantee portions of the principal, interest or other amounts in connection with other unconsolidated joint venture borrowings. In addition to the financial guarantees referenced above, the Company has agreed to customary environmental indemnifications and nonrecourse carve-outs (e.g., guarantees against fraud, misrepresentation and bankruptcy) on certain of its unconsolidated joint venture loans.

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. On September 18, 2014, the Company received an initial distribution totaling approximately $7.7 million, which is included in Base Rent in the accompanying Consolidated Statements of Operations for the three and nine months ended September 30, 2014, leaving a remaining claim of approximately $37.5 million. Recently, claims of similar priority to that of the Company’s remaining claim were quoted privately within a range of $0.25 to $0.26 per $1.00. The Company will continue to evaluate whether to attempt to sell the remaining claim or wait until the trustee distributes proceeds from the Lehman estate. Given the inherent uncertainties in bankruptcy proceedings, there can be no assurance as to the timing or amount of 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 September 30, 2014.

Insurance

The Company carries insurance coverage on its properties of types and in amounts and with deductibles that it believes are in line with coverage customarily obtained by owners of similar properties. In response to the uncertainty in the insurance market following the terrorist attacks of September 11, 2001, the Federal Terrorism Risk Insurance Act (as amended, “TRIA”) was enacted in November 2002 to require regulated insurers to make available coverage for “certified” acts of terrorism (as defined by the statute). The expiration date of TRIA was extended to December 31, 2014 by the Terrorism Risk Insurance Program Reauthorization Act of 2007 (“TRIPRA”) and the Company can provide no assurance that it will be extended further. Currently, 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. Through June 9, 2014, $1.375 billion of the Terrorism Coverage for 767 Fifth Avenue in excess of $250 million was provided by NYXP, LLC (“NYXP”), as a direct insurer. After June 9, 2014, all of the Terrorism Coverage for 767 Fifth Avenue has been provided by third party insurers. The Company also currently carries nuclear, biological, chemical and radiological terrorism insurance coverage for acts of terrorism certified under 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 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 and the Terrorism Coverage provided by NYXP are backstopped by the Federal Government if the aggregate industry insured losses resulting from a certified act of terrorism exceed a “program trigger.” The program trigger is $100.0 million and the coinsurance is 15%. Under TRIPRA, 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 TRIPRA. The Company may elect to terminate the NBCR Coverage if the Federal Government seeks recoupment for losses paid under TRIA, if there is a change in its portfolio or for any other reason. In the event TRIPRA is not extended beyond December 31, 2014, (i) the Company’s $1.0 billion portfolio property insurance program and the $250 million of additional Terrorism Coverage for 601 Lexington Avenue will continue to provide Terrorism Coverage through the expiration of the program on March 1, 2015, (ii) the $1.625 billion property insurance program for 767 Fifth Avenue will continue to provide Terrorism Coverage through the expiration of the program on June 9, 2015, (iii) the Company will evaluate alternative approaches to secure coverage for acts of terrorism thereby potentially increasing our overall cost of insurance, (iv) if such insurance is not available at commercially reasonable rates

with limits equal to our current coverage or at all, the Company may not continue to have full occurrence limit coverage for acts of terrorism, (v) the Company may not satisfy the insurance requirements under existing or future debt financings secured by individual properties, (vi) the Company may not be able to obtain future debt financings secured by individual properties and (vii) the Company may cancel the insurance policies issued by IXP for the NBCR Coverage. The Company intends to continue to monitor the scope, nature and cost of available terrorism insurance and maintain terrorism insurance in amounts and on terms that are commercially reasonable.

The Company also currently carries earthquake insurance on its properties located in areas known to be subject to earthquakes in an amount and subject to self-insurance that the Company believes is commercially reasonable. In addition, this insurance is subject to a deductible in the amount of 5% of the value of the affected property. Specifically, the Company currently carries earthquake insurance which covers its San Francisco region (excluding 535 Mission Street and Salesforce Tower (formerly Transbay Tower)) with a $120 million per occurrence limit and a $120 million annual aggregate limit, $20 million of which is provided by IXP, as a direct insurer. The builders risk policy maintained for the development of 535 Mission Street in San Francisco includes a $15 million per occurrence and annual aggregate limit of earthquake coverage. In addition, the builders risk policy maintained for the development of Salesforce Tower in San Francisco includes a $60 million per occurrence and annual aggregate limit of earthquake coverage (increased from $15 million on July 29, 2014). 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 properties and the Company’s NBCR Coverage. NYXP, a captive insurance company which is a wholly-owned subsidiary of the Company, acted as a direct insurer with respect to a portion of the Company’s Terrorism Coverage for 767 Fifth Avenue through June 9, 2014. NYXP only insured losses which exceeded the program trigger under TRIA and NYXP reinsured with a third-party insurance company any coinsurance payable under TRIA. Insofar as the Company owns IXP and NYXP, it is responsible for their liquidity and capital resources, and the accounts of IXP and NYXP 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 and NYXP would also be responsible for any recoupment charges by the Federal Government in the event losses are paid out and their insurance policies are maintained after the payout by the Federal Government. If the Company experiences a loss and IXP or NYXP are required to pay under their insurance policies, the Company would ultimately record the loss to the extent of the required payment. Therefore, insurance coverage provided by IXP and NYXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance. In addition, the Operating Partnership has issued a guarantee to cover liabilities of IXP in the amount of $20.0 million.

The mortgages on the Company’s properties typically contain requirements concerning the financial ratings of the insurers who provide policies covering the property. The Company provides the lenders on a regular basis with the identity of the insurance companies in the Company’s insurance programs. The ratings of some of the Company’s insurers are below the rating requirements in some of the Company’s loan agreements and the lenders for these loans could attempt to claim that an event of default has occurred under the loan. The Company believes it could obtain insurance with insurers which satisfy the rating requirements. Additionally, in the future, the Company’s ability to obtain debt financing secured by individual properties, or the terms of such financing, may be adversely affected if lenders generally insist on ratings for insurers or amounts of insurance which are difficult to obtain or which result in a commercially unreasonable premium. There can be no assurance that a deficiency in the financial ratings of one or more of the Company’s insurers will not have a material adverse effect on the Company.

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.

8. Noncontrolling Interests

Noncontrolling interests relate to the interests in the Operating Partnership not owned by the Company and interests in consolidated property partnerships not wholly-owned by the Company. As of September 30, 2014, the noncontrolling interests in the Operating Partnership consisted of 16,456,297 OP Units, 1,505,386 LTIP Units, 394,590 2012 OPP Units, 314,974 2013 MYLTIP Units, 483,555 2014 MYLTIP Units and 40,440 Series Four Preferred Units (none of which are convertible into OP Units) held by parties other than the Company.

Noncontrolling Interest—Redeemable Preferred Units of the Operating Partnership

On March 11, 2014, the Company notified the holders of the outstanding Series Two Preferred Units that it had elected to redeem all of such Series Two Preferred Units on May 12, 2014. As a result of the Company’s election to redeem the units, all of the holders of the Series Two Preferred Units elected to convert such units into 1.312336 OP Units, or an aggregate of 874,168 OP Units, on or before May 12, 2014. As of May 12, 2014, the holders of all remaining 666,116 Series Two Preferred Units converted such units into an aggregate of 874,168 OP Units. The Series Two Preferred Units bore a preferred distribution equal to the greater of (1) the distribution which would have been paid in respect of the Series Two Preferred Unit had such Series Two Preferred Unit been converted into an OP Unit (including both regular and special distributions) or (2) 6.00% per annum on a liquidation preference of $50.00 per unit, and were convertible into OP Units at a rate of $38.10 per Preferred Unit (1.312336 OP Units for each Preferred Unit). In connection with the conversion of the remaining Series Two Preferred Units in May 2014, the Operating Partnership paid accrued and unpaid distributions which included the special cash distribution on an as-converted basis. On February 18, 2014, the Operating Partnership paid a distribution on its outstanding Series Two Preferred Units of $0.85302 per unit. Due to the holders’ redemption option existing outside the control of the Company, the Series Two Preferred Units were presented outside of permanent equity in the Company’s Consolidated Balance Sheets.

The Preferred Units at September 30, 2014 consisted of 40,440 Series Four Preferred Units, which bear a preferred distribution equal to 2.00% per annum on a liquidation preference of $50.00 per unit and are not convertible into OP Units. The holders of Series Four Preferred Units have the right, at certain times and subject to certain conditions set forth in the Certificate of Designations establishing the rights, limitations and preferences of the Series Four Preferred Units, to require the Operating Partnership to redeem all of their their units for cash at the redemption price of $50.00 per unit. The Operating Partnership also has the right, at certain times and subject to certain conditions, to redeem all of the Series Four Preferred Units for cash at the redemption price of $50.00 per unit. In order to secure the performance of certain post-issuance obligations by the holders, all of such outstanding Series Four Preferred Units were subject to forfeiture pursuant to the terms of a pledge agreement and not eligible for redemption until and unless such security interest is released. On May 19, 2014, the Company’s Operating Partnership released to the holders 319,687 Series Four Preferred Units that were previously subject to the security interest. On July 3, 2014, the Company’s Operating Partnership redeemed such units for cash totaling approximately $16.0 million, plus accrued and unpaid distributions. An aggregate of 40,440 Series Four Preferred Units remain outstanding and subject to the security interest under the pledge agreement (See Note 13). Due to the holders’ redemption option existing outside the control of the Company, the Series Four Preferred Units are presented outside of permanent equity in the Company’s Consolidated Balance Sheets.

On February 18, 2014, the Operating Partnership paid a distribution on its outstanding Series Four Preferred Units of $0.25 per unit. On May 15, 2014, the Operating Partnership paid a distribution on its outstanding Series Four Preferred Units of $0.25 per unit. On August 15, 2014, the Operating Partnership paid a distribution on its outstanding Series Four Preferred Units of $0.25 per unit.

Noncontrolling Interest—Redeemable Interest in Property Partnership

On October 4, 2012, the Company completed the formation of a joint venture that owns and operates Fountain Square located in Reston, Virginia. The joint venture partner contributed the property valued at approximately $385.0 million and related mortgage indebtedness totaling approximately $211.3 million for a nominal 50% interest in the joint venture. The Company contributed cash totaling approximately $87.0 million for its nominal 50% interest, which cash was distributed to the joint venture partner. Pursuant to the joint venture agreement (i) the Company has rights to acquire the partner’s nominal 50% interest and (ii) the partner has the right to cause the Company to acquire the partner’s interest on January 4, 2016, in each case at a fixed price totaling approximately $102.0 million in cash. The fixed price option rights expire on January 31, 2016. The Company is consolidating this joint venture due to the Company’s right to acquire the partner’s nominal 50% interest. The Company initially recorded the noncontrolling interest at its acquisition-date fair value as temporary equity, due to the redemption option existing outside the control of the Company. The Company will accrete the changes in the redemption value quarterly over the period from the acquisition date to the earliest redemption date using the effective interest method. The Company will record the accretion after the allocation of net income and distributions of cash flow to the noncontrolling interest account balance.

The following table reflects the activity of the noncontrolling interest—redeemable interest in property partnership in the Company’s Fountain Square consolidated joint venture for the nine months ended September 30, 2014 and 2013 (in thousands):

Noncontrolling Interest—Common Units of the Operating Partnership

During the nine months ended September 30, 2014, 70,422 OP Units were presented by the holders for redemption (including 67,368 OP Units issued upon conversion of LTIP Units) and were redeemed by the Company in exchange for an equal number of shares of Common Stock.

At September 30, 2014, the Company had outstanding 394,590 2012 OPP Units, 314,974 2013 MYLTIP Units and 483,555 2014 MYLTIP Units. Prior to the measurement date (February 6, 2015 for 2012 OPP Units, February 4, 2016 for 2013 MYLTIP Units and February 3, 2017 for 2014 MYLTIP Units), holders of OPP Units and MYLTIP Units will be entitled to receive per unit distributions equal to one-tenth (10%) of the regular quarterly distributions payable on an OP Unit, but will not be entitled to receive any special distributions. After the measurement date, the number of OPP Units and MYLTIP Units, both vested and unvested, that OPP and 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 January 31, 2014, the measurement period for the Company’s 2011 OPP Unit awards expired and the Company’s TRS was not sufficient for employees to earn and therefore become eligible to vest in any of the 2011 OPP Unit awards. As a result, the Company accelerated the then remaining unrecognized compensation expense totaling approximately $1.2 million during the nine months ended September 30, 2014. Accordingly, all 2011 OPP Unit awards were automatically forfeited.

On January 29, 2014, the Operating Partnership paid a special cash distribution on the OP Units and LTIP Units in the amount of $2.25 per unit, a regular quarterly cash distribution on the OP Units and LTIP Units in the amount of $0.65 per unit, and a regular quarterly distribution on the 2011 OPP Units, 2012 OPP Units and 2013 MYLTIP Units in the amount of $0.065 per unit, to holders of record as of the close of business on December 31, 2013. The special cash distribution was in addition to the regular quarterly distribution on the OP Units and LTIP Units. Holders of the 2011 OPP Units, 2012 OPP Units, 2013 MYLTIP Units and 2014 MYLTIP Units are not entitled to receive any special distributions. On April 30, 2014, the Operating Partnership paid a distribution on the OP Units and LTIP Units in the amount of $0.65 per unit, and a distribution on the 2012 OPP Units, 2013 MYLTIP Units and 2014 MYLTIP Units in the amount of $0.065 per unit, to holders of record as of the close of business on March 31, 2014. On July 31, 2014, the Operating Partnership paid a distribution on the OP Units and LTIP Units in the amount of $0.65 per unit, and a distribution on the 2012 OPP Units, 2013 MYLTIP Units and

2014 MYLTIP Units in the amount of $0.065 per unit, to holders of record as of the close of business on June 30, 2014. On September 11, 2014, Boston Properties, Inc., as general partner of the Operating Partnership, declared a distribution on the OP Units and LTIP Units in the amount of $0.65 per unit and a distribution on the 2012 OPP Units, 2013 MYLTIP Units and 2014 MYLTIP Units in the amount of $0.065 per unit, in each case payable on October 31, 2014 to holders of record as of the close of business on September 30, 2014.

A holder of an OP Unit may present such OP Unit to the Operating 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, the Operating Partnership must redeem such OP Unit for cash equal to the then value of a share of common stock of the Company. The Company 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 the Company and including LTIP Units assuming that all conditions had been met for the conversion thereof) had all of such units been redeemed at September 30, 2014 was approximately $2.1 billion based on the closing price of the Company’s common stock of $115.76 per share on September 30, 2014.

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 $716.6 million at September 30, 2014 and approximately $726.1 million at December 31, 2013, are included in Noncontrolling Interests—Property Partnerships on the accompanying Consolidated Balance Sheets.

On February 7, 2013, the partner in the Company’s Salesforce Tower (formerly Transbay Tower) joint venture issued a notice that it was electing under the joint venture agreement to reduce its nominal ownership interest in the venture from 50% to 5%. On February 26, 2013, the Company issued a notice to the partner electing to proceed with the venture on that basis. As a result, the Company has a 95% nominal interest in and is consolidating the joint venture. Under the joint venture agreement, if certain return thresholds are achieved the partner will be entitled to an additional promoted interest. In addition, if the Company elects to fund the construction of Salesforce Tower without a construction loan (or a construction loan of less than 50% of project costs), then the partner has the option to require the Company to fund up to 2.5% of the total project costs (i.e., of 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 construction loan interest rates. Also, under the agreement, (1) the partner has the right to cause the Company to purchase the partner’s interest after the defined stabilization date and (2) the Company has the right to acquire the partner’s interest on the third anniversary of the stabilization date, in each case at an agreed upon purchase price or appraised value.

On May 31, 2013, the Company’s two joint venture partners in 767 Venture, LLC (the entity that owns 767 Fifth Avenue(the General Motors Building) in New York City) transferred all of their interests in the joint venture to third parties. In connection with the transfer, the Company and its new joint venture partners modified the Company’s relative decision making authority and consent rights with respect to the joint venture’s assets and operations. These changes resulted in the Company having sufficient financial and operating control over 767 Venture, LLC such that the Company now accounts for the assets, liabilities and operations of 767 Venture, LLC on a consolidated basis in its financial statements instead of under the equity method of accounting. Upon consolidation, the Company recognized the new joint venture partners’ aggregate 40% equity interest at its aggregate fair value of approximately $480.9 million within Noncontrolling Interests—Property Partnerships on the accompanying Consolidated Balance Sheets.

On October 9, 2013, the Company completed the sale of a 45% ownership interest in its Times Square Tower property for a gross sale price of $684.0 million in cash. Net cash proceeds totaled approximately $673.1 million, after the payment of transaction costs. In connection with the sale, the Company formed a joint venture

with the buyer and will provide customary property management and leasing services to the joint venture. Times Square Tower is an approximately 1,246,000 net rentable square foot Class A office tower located in New York City. The transaction did not qualify as a sale of real estate for financial reporting purposes because the Company continues to control the joint venture and will therefore continue to account for the entity on a consolidated basis in its financial statements. The Company has accounted for the transaction as an equity transaction and has recognized noncontrolling interest in its Consolidated Balance Sheets totaling approximately $243.5 million, which is equal to 45% of the carrying value of the total equity of the property immediately prior to the transaction.

9. Stockholders’ Equity

As of September 30, 2014, the Company had 153,099,786 shares of Common Stock outstanding.

On June 3, 2014, the Company established a new “at the market” (ATM) stock offering program through which it may sell from time to time up to an aggregate of $600.0 million of its common stock through sales agents over a three-year period. This program replaced the Company’s prior $600.0 million ATM stock offering program that expired on June 2, 2014 with approximately $305.3 million of unsold common stock. The Company intends to use the net proceeds from any offering for general business purposes, which may include investment opportunities and debt reduction. No shares of common stock have been issued under this new ATM stock offering program.

During the nine months ended September 30, 2014, the Company issued 70,422 shares of Common Stock in connection with the redemption of an equal number of redeemable OP Units from third parties.

During the nine months ended September 30, 2014, the Company issued 17,124 shares of Common Stock upon the exercise of options to purchase Common Stock by certain employees.

On January 29, 2014, the Company paid a special cash dividend and regular quarterly dividend aggregating $2.90 per share of Common Stock to shareholders of record as of the close of business on December 31, 2013. On April 30, 2014, the Company paid a dividend of $0.65 per share of Common Stock to shareholders of record as of the close of business on March 31, 2014. On July 31, 2014, the Company paid a dividend of $0.65 per share of Common Stock to shareholders of record as of the close of business on June 30, 2014. On September 11, 2014, the Company’s Board of Directors declared a dividend of $0.65 per share of Common Stock payable on October 31, 2014 to shareholders of record as of the close of business on September 30, 2014.

As of September 30, 2014, the Company had 80,000 shares (8,000,000 depositary shares each representing 1/100th of a share) outstanding of its 5.25% Series B Cumulative Redeemable Preferred Stock with a liquidation preference of $2,500.00 per share ($25.00 per depositary share). The Company pays cumulative cash dividends on the Series B Preferred Stock at a rate of 5.25% per annum of the $2,500.00 liquidation preference per share. The Company may not redeem the Series B Preferred Stock prior to March 27, 2018, except in certain circumstances relating to the preservation of the Company’s REIT status. On or after March 27, 2018, the Company, at its option, may redeem the Series B Preferred Stock for a cash redemption price of $2,500.00 per share ($25.00 per depositary 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.

On February 18, 2014, the Company paid a dividend on its outstanding Series B Preferred Stock of $32.8125 per share. On May 15, 2014, the Company paid a dividend on its outstanding Series B Preferred Stock of $32.8125 per share. On August 15, 2014, the Company paid a dividend on its outstanding Series B Preferred Stock of $32.8125 per share. On September 11, 2014, the Company’s Board of Directors declared a dividend of $32.8125 per share of Series B Preferred Stock payable on November 17, 2014 to shareholders of record as of the close of business on November 5, 2014.

10. Earnings Per Share

The following table provides a reconciliation of both the net income attributable to Boston Properties, Inc. 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. by the weighted-average number of common shares outstanding during the period. The terms of the Series Two Preferred Units enable the holders to obtain OP Units of the Operating Partnership, as well as Common Stock of the Company, and as a result these are considered participating securities. 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 the Company, LTIP Units, OPP Units and MYLTIP Units are considered participating securities. Participating securities are included in the computation of basic EPS of the Company using the two-class method. Participating securities are included in the computation of diluted EPS of the Company using the if-converted method if the impact is dilutive. Because the OPP Units and MYLTIP Units require the Company to outperform absolute and relative return thresholds, unless such thresholds have been met by the end of the applicable reporting period, the Company excludes such units from the diluted EPS calculation. Other potentially dilutive common shares, including stock options, restricted stock and other securities of the Operating Partnership that are exchangeable for the Company’s Common Stock, and the related impact on earnings, are considered when calculating diluted EPS.

11. Stock Option and Incentive Plan

On January 27, 2014, the Company’s Compensation Committee approved the 2014 MYLTIP awards under the Company’s 2012 Plan to certain officers and employees of the Company. The 2014 MYLTIP awards utilize TRS over a three-year measurement period, on an annualized, compounded basis, as the performance metric. Earned awards, if any, will be based on the Company’s TRS relative to (i) the Cohen & Steers Realty Majors Portfolio Index (50% weight) and (ii) the NAREIT Office Index adjusted to exclude the Company (50% weight). Earned awards will range from $0 to a maximum of approximately $40.2 million depending on the Company’s TRS relative to the two indices, with four tiers (threshold: approximately $6.7 million; target: approximately $13.4 million; high: approximately $26.8 million; and exceptional: approximately $40.2 million) and linear interpolation between tiers. Earned awards measured on the basis of relative TRS performance are subject to an absolute TRS component in the form of relatively simple modifiers that (A) reduce the level of earned awards in the event the Company’s annualized TRS is less than 0% and (B) cause some awards to be earned in the event the Company’s annualized TRS is more than 12% even though on a relative basis alone the Company’s TRS would not result in any earned awards.

Earned awards (if any) will vest 50% on February 3, 2017 and 50% on February 3, 2018, based on continued employment. Vesting will be accelerated in the event of a change in control, termination of employment by the Company without cause, termination of employment by the award recipient for good reason, death, disability or retirement. If there is a change of control prior to February 3, 2017, earned awards will be calculated as of the date of the change of control based upon performance through such date as measured against

performance hurdles (without proration). The 2014 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 the FASB’s ASC 718 “Compensation-Stock Compensation” the 2014 MYLTIP awards have an aggregate value of approximately $12.7 million, which amount will generally be amortized into earnings over the four-year plan period under the graded vesting method.

During the nine months ended September 30, 2014, the Company issued 23,968 shares of restricted common stock, no non-qualified stock options, 127,094 LTIP Units and 485,459 2014 MYLTIP Units to employees and non-employee directors under the 2012 Plan. Employees and non-employee directors paid $0.01 per share of restricted common stock and $0.25 per LTIP Unit and 2014 MYLTIP Unit. An LTIP Unit is generally the economic equivalent of a share of restricted stock in the Company. 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, as adjusted for forfeitures, and the closing price of the Company’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. The shares of restricted stock granted during the nine months ended September 30, 2014 were valued at approximately $2.6 million ($109.27 per share weighted-average). The LTIP Units granted were valued at approximately $12.8 million ($100.61 per unit weighted-average fair value) using a Monte Carlo simulation method model. The per unit fair value of each LTIP Unit granted was estimated on the date of grant using the following assumptions: an expected life of 5.7 years, a risk-free interest rate of 1.84% and an expected price volatility of 27%. As the 2011 OPP Units, 2012 OPP Units, 2013 MYLTIP Units and 2014 MYLTIP Units are subject to both a service condition and a market condition, the Company recognizes the compensation expense related to the 2011 OPP Units, 2012 OPP Units, 2013 MYLTIP Units and 2014 MYLTIP Units 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. Dividends paid on both vested and unvested shares of restricted stock are charged directly to Dividends in Excess of Earnings in the Consolidated Balance Sheets. Aggregate stock-based compensation expense associated with restricted stock, non-qualified stock options, LTIP Units, 2011 OPP Units, 2012 OPP Units, 2013 MYLTIP Units and 2014 MYLTIP Units was approximately $5.0 million and $6.2 million for the three months ended September 30, 2014 and 2013, respectively, and approximately $21.0 million and $38.1 million for the nine months ended September 30, 2014 and 2013, respectively. On January 31, 2014, the measurement period for the Company’s 2011 OPP Awards expired and the Company’s TRS was not sufficient for employees to earn and therefore become eligible to vest in any of the 2011 OPP Awards. As a result, the Company accelerated the then remaining unrecognized compensation expense totaling approximately $1.2 million. For the three and nine months ended September 30, 2013, stock-based compensation expense includes approximately $1.6 million and $20.2 million, respectively, consisting of the acceleration of the expense of the Company’s Executive Chairman’s stock-based compensation awards and the stock-based compensation awards associated with his transition benefits agreement related to the Company’s succession planning. At September 30, 2014, there was $19.7 million of unrecognized compensation expense related to unvested restricted stock and LTIP Units and $16.5 million of unrecognized compensation expense related to unvested 2012 OPP Units, 2013 MYLTIP Units and 2014 MYLTIP Units that is expected to be recognized over a weighted-average period of approximately 2.9 years.

12. Segment Information

The Company’s segments are based on the Company’s method of internal reporting which classifies its operations by both geographic area and property type. Beginning on January 1, 2014, the properties that were historically part of the Princeton region are reflected as the suburban component of the New York region. Therefore, the operations for the Princeton region have been included in the New York region. Accordingly, amounts reflected below for the New York region have been adjusted to reflect the Company’s retrospective inclusion of the Princeton region in the New York region. The Company’s segments by geographic area are Boston, New York, San Francisco and Washington, DC. Segments by property type include: Class A Office, Office/Technical, Residential and Hotel.

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. Interest and other income, development and management services income, general and administrative expenses, transaction costs, impairment loss, interest expense, depreciation and amortization expense, gains (losses) from investments in securities, gains (losses) from early extinguishments of debt, income from unconsolidated joint ventures, gains on consolidation of joint ventures, discontinued operations, gains on sales of real estate and noncontrolling interests are not included in Net Operating Income as internal reporting addresses these items on a corporate level.

Net Operating Income is not a measure of operating results or cash flows from operating activities as measured by accounting principles generally accepted in the United States of America, and it is not indicative of cash available to fund cash needs and should not be considered an alternative to cash flows as a measure of liquidity. All companies may not calculate Net Operating Income in the same manner. The Company considers Net Operating Income to be an appropriate supplemental measure to net income because it helps both investors and management to understand the core operations of the Company’s properties. The Company’s management also uses Net Operating Income to evaluate regional property level performance and to make decisions about resource allocations. Further, the Company believes Net Operating Income is useful to investors as a performance measure because, when compared across periods, Net Operating Income reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspectives not immediately apparent from net income attributable to Boston Properties, Inc.

On May 31, 2013, the Company’s two joint venture partners in 767 Venture, LLC (the entity that owns 767 Fifth Avenue (the General Motors Building) located in New York City) transferred all of their interests in the joint venture to third parties. Effective as of May 31, 2013, the Company accounts for the assets, liabilities and operations of 767 Venture, LLC on a consolidated basis in its financial statements instead of under the equity method of accounting. Upon consolidation, the operations for this building are included in the New York region.

13. Subsequent Events

On October 2, 2014, the Company completed the sale of its Patriots Park properties located in Reston, Virginia for a gross sale price of $321.0 million, which exceeded the carrying value of the properties. Patriots Park consists of three Class A office properties aggregating approximately 706,000 net rentable square feet.

On October 16, 2014, the Company’s Operating Partnership released to the holders 27,773 Series Four Preferred Units that were previously subject to a security interest under a pledge agreement (See Note 8). On November 5, 2014, the Company’s Operating Partnership redeemed such units for cash totaling approximately $1.4 million. An aggregate of 12,667 Series Four Preferred Units remain outstanding and subject to the security interest under the pledge agreement.

On October 22, 2014, MIT exercised its right to purchase the Company’s 415 Main Street property (formerly Seven Cambridge Center) located in Cambridge, Massachusetts on February 1, 2016 for approximately $106 million. As part of its lease signed on July 14, 2004, MIT was granted a fixed price option to purchase the

building at the beginning of the 11th lease year. 415 Main Street is an Office/Technical property with approximately 231,000 net rentable square feet occupied by the Broad Institute. The sale is subject to the satisfaction of customary closing conditions and there can be no assurance that the sale will be consummated on the terms currently contemplated or at all.

On October 24, 2014, the Company completed the sale of a parcel of land at 130 Third Avenue in Waltham, Massachusetts that is permitted for 129,000 square feet for a sale price of approximately $14.3 million, which exceeded the carrying value of the property.

On October 24, 2014, a joint venture in which the Company has 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 construction loan totaled approximately $13.9 million and bore interest at a variable rate equal to LIBOR plus 1.65% per annum and was scheduled to mature on November 17, 2014. The extended loan has a total commitment amount of $16.4 million, bears interest at a variable rate equal to LIBOR plus 2.25% per annum and matures on November 17, 2015. Annapolis Junction Building Six is a Class A office property with approximately 119,000 net rentable square feet located in Annapolis, Maryland.

On October 30, 2014, the Company completed the sale of a 45% interest in each of 601 Lexington Avenue in New York City and Atlantic Wharf Office Building and 100 Federal Street in Boston for an aggregate gross sales price of approximately $1.827 billion in cash, less the partner’s pro rata share of the indebtedness secured by 601 Lexington Avenue, subject to certain prorations and adjustments. In connection with the sale, the Company formed a joint venture for each property with the buyer and will provide customary property management and leasing services to the joint ventures. 601 Lexington Avenue is a 1,669,000 square foot Class A office complex located in Midtown Manhattan. The property consists of a 59-story tower as well as a six-story low-rise office and retail building. The property is subject to existing mortgage indebtedness of approximately $712.9 million. The Atlantic Wharf Office Building is a 791,000 square foot Class A office tower located on Boston’s Waterfront. 100 Federal Street is a 1,323,000 square foot Class A office tower located in Boston’s Financial District. The transaction did not qualify as a sale of real estate for financial reporting purposes as the Company continues to control the joint ventures and will therefore continue to account for the properties on a consolidated basis in its financial statements.

On November 1, 2014, the Company partially placed in-service 535 Mission Street, a Class A office project with approximately 307,000 net rentable square feet located in San Francisco, California.

On November 3, 2014, the Company’s Operating Partnership issued notices to redeem on December 15, 2014 (i) $300.0 million in aggregate principal amount of its 5.625% senior notes due 2015, which were scheduled to mature on April 15, 2015 (the “5.625% Notes”), and (ii) $250.0 million in aggregate principal amount of its 5.000% senior notes due 2015, which were scheduled to mature on June 1, 2015 (the “5.000% Notes”). The redemption price for each series of notes will equal the sum of (a) the present values as of the redemption date of the remaining scheduled payments of principal and interest from the redemption date to maturity (excluding any accrued and unpaid interest) discounted on a semi-annual basis at a rate equal to the yield to maturity of a comparable United States Treasury security plus (i) in the case of the 5.625% Notes, 0.35% or (ii) in the case of the 5.000% Notes, 0.25%, plus (b) accrued interest to, but excluding, December 15, 2014, as provided in the applicable indenture. The redemption price for each series of notes will be calculated three business days prior to the redemption date and will be payable on December 15, 2014 in accordance with the terms of the applicable indentures.

On November 6, 2014, the Company entered into an option agreement pursuant to which the Company has been granted an option to purchase real property located at 425 Fourth Street in San Francisco, California. In connection with the execution of the agreement, the Company paid a non-refundable option payment to the current owner of $1.0 million. The Company intends to pursue the entitlements necessary to develop the property. The purchase price has not been determined and is dependent on the entitlements obtained. There can be no assurance that the Company will be successful in obtaining the desired entitlements or that it will ultimately determine to exercise the option.

The following discussion should be read in conjunction with the financial statements and notes thereto appearing elsewhere in this report. This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the federal securities laws. We caution investors that any forward-looking statements presented in this report, or which management may make orally or in writing from time to time, are based on beliefs and assumptions made by, and information currently available to, management. When used, the words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “project,” “result,” “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:

•

the continuing impacts of the relatively weak economic recovery, relatively high unemployment and other macroeconomic trends, which are having and may continue to 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 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;

•

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, 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, including the impact of higher interest rates on the cost and/or availability of financing;

•

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 our 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 other risk factors identified in our most recently filed Annual Report on Form 10-K, including those described under the caption “Risk Factors.”

The risks set forth above are not exhaustive. Other sections of this report may 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 it 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. Investors should also refer to our most recent Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q for future periods and Current Reports on Form 8-K as we file them with the SEC, and to other materials we may furnish to the public from time to time through Forms 8-K or otherwise, for a discussion of risks and uncertainties that may cause actual results, performance or achievements to differ materially from those expressed or implied by forward-looking statements. We expressly disclaim any responsibility to update any forward-looking statements to reflect changes in underlying assumptions or factors, new information, future events, or otherwise, and you should not rely upon these forward-looking statements after the date of this report.

Overview

We are a fully integrated self-administered and self-managed REIT and one of the largest owners and developers of Class A office properties in the United States. Our properties are concentrated in four markets-Boston, New York, San Francisco and Washington, DC. We generate revenue and cash primarily by leasing Class A office space to our tenants. Factors we consider when we lease space include 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, current and anticipated operating costs and real estate taxes, our current and anticipated vacancy, current and anticipated future demand for office space and general economic factors. From time to time, we also generate cash through the sale of assets.

Our core strategy has always been to own, operate and develop properties in supply-constrained markets with high barriers to entry and to focus on executing long-term leases with financially strong tenants. Historically, this combination has tended to reduce our exposure in down cycles and enhance revenues as market conditions improve. To be successful in the current leasing environment, we believe all aspects of the tenant-landlord relationship must be considered. In this regard, we believe that our understanding of tenants’ short- and

long-term space utilization and amenity needs in the local markets in which we operate, our relationships with local brokers, our reputation as a premier developer, owner and operator of Class A office properties, our financial strength and our ability to maintain high building standards provide us with a competitive advantage.

Our portfolio is concentrated in markets and submarkets which include traditional tenants, such as government, financial services and law firms, as well as businesses that are oriented on new ideas, such as technology, advertising, media and information distribution (often referred to as “TAMI”), mobility, life sciences and medical devices. We continue to benefit from this as the TAMI segments of the economy are expanding and leasing additional office space. This is particularly true in the San Francisco Central Business District (“CBD”), Silicon Valley, Cambridge, Massachusetts and suburban Boston submarkets where we are seeing increasing levels of leasing activity. However, there continue to be headwinds against more rapid improvements in the overall office business. The strongest force is densification, which occurs as businesses seek to cater to more collaborative work environments and fit people more efficiently into less space. In addition, markets such as Washington, DC and, to a lesser extent, midtown Manhattan which are more reliant on traditional tenants are experiencing relatively lower levels of activity and growth. We are also seeing new construction in our markets accommodating both growing tenant sectors and traditional tenants seeking more efficient space utilization. This may result in an increase in supply and create challenges for us to increase our occupancy and the rents we can realize. We are proactively managing our near- and medium-term lease expirations. As our tenants adjust their space needs, we may extend the leases of quality tenants on a long-term basis, invest in tenant improvements to improve space utilization and take back portions of their space to re-lease to other tenants at current rates. In some cases, this may result in space down-time and foregone revenue in the short-term, but better position us for more stable long-term revenues. Despite these challenges, we remain optimistic about the long-term operating fundamentals in all of our markets.

Leasing activity in our portfolio remains strong. During the third quarter of 2014, we signed approximately 1.9 million square feet of leases covering vacant space, pre-leasing for our development projects and extensions and expansions, including approximately 650,000 square feet of early renewals with two law firms and an expanding existing tenant. This total exceeds our quarterly average for the past five years by approximately 46%, with the Boston and New York regions being the largest contributors. The overall percentage of leased space for the 158 properties in service (excluding the three in-service residential properties and the hotel) as of September 30, 2014 was 92.0% compared to 93.0% at June 30, 2014. The decrease of 1.0% is due to the placing in-service of 250 West 55th Street, our approximately 988,000 square foot office building in New York City, which was approximately 54% leased as of September 30, 2014 and is currently 77% leased, including leases with future commencement dates.

In the New York region, during the third quarter we completed approximately 592,000 square feet of leasing in twenty lease transactions, including a 388,000 square foot early renewal with a law firm at 767 Fifth Avenue (The General Motors Building) for fifteen additional years. In addition, we ceased interest capitalization on September 1, 2014 and fully placed in-service our 250 West 55th Street development project. We have limited rollover exposure through the end of 2015 of approximately 4.5%. We are actively engaged with several additional law firm tenants that currently lease approximately 937,000 square feet under leases that expire in 2017 and thereafter regarding possible renewals.

In our Washington, DC region, the overall leasing activity continues to be slow and public sector and defense contractor demand has been adversely impacted by continued federal budgetary uncertainty, sequestration and the reductions in discretionary spending programs. Our near-term exposure in the Washington, DC CBD is limited due to our strong office occupancy rate of 95.7%. We are actively engaging our law firm tenants with future lease expirations, including two firms currently occupying approximately 540,000 square feet in our CBD portfolio, to provide new space configurations in exchange for extended lease terms at market rents. In addition, our suburban Washington, DC assets are 96.4% leased at September 30, 2014, with moderate rollover/exposure through the end of 2015 of approximately 11.5%. We anticipate our occupancy in the Washington, DC region will decline from 96.1%, at September 30, 2014, to an average of 93.3% in 2015.

In the Boston region, the expansion of the life sciences and technology industry is positively impacting each of the submarkets in which we operate. Our assets in the Boston CBD are 93.2% leased, with approximately 308,000 square feet of the Boston CBD portfolio vacancy leased to a tenant that will commence its lease in 2015. Through the end of 2015, leases for approximately 715,000 square feet are scheduled to expire, including two large blocks totaling approximately 414,000 square feet in the John Hancock Tower. This space includes (1) 170,000 square feet at the base of the building where we anticipate creating a new second lobby and rebranding this portion of the building “120 St. James Street” and (2) 244,000 square feet in the tower. While we believe all of this space is highly marketable and current market rents are greater than the expiring rents, we expect much of this space will be vacant during 2015 as new tenants lease and build out their space. In conjunction with the construction of our 888 Boylston Street 425,000 square foot development project, we expect to complete a major renovation of the Prudential Center Food Court and create additional retail space during 2015 which, upon completion, will enhance our revenues and our tenants’ experience at the Prudential Center. The East Cambridge submarket is the strongest submarket in the region and our Cambridge portfolio is approximately 99.6% leased. In the suburbs of Boston along the Route 128 corridor, we are also benefiting from the strong tenant demand in the technology and life sciences industries with the completion of approximately 487,000 square feet of leases during the quarter, including an approximately 152,000 square foot lease for our anchor tenant at 10 CityPoint, a 245,000 square foot development project in Waltham, Massachusetts.

The San Francisco CBD and Silicon Valley submarkets continue to benefit from business expansion and job growth, particularly in the technology sector, which has resulted in positive absorption, lower vacancy and increasing rental rates. During the third quarter of 2014, we leased approximately 121,000 square feet, with a year-to-date total space leased of approximately 1.4 million square feet. We have approximately 426,000 square feet of space expiring in the San Francisco region through the end of 2015 at rents that are below current market rents. Construction of 535 Mission Street is on schedule and we expect to be able to deliver space to tenants and commence revenue recognition for the initial tenant in the fourth quarter of 2014.

The table below details the leasing activity during the three and nine months ended September 30, 2014:


	Three Months Ended September 30, 2014			Nine Months Ended September 30, 2014

(1)

Second generation leases are defined as leases for space that had previously been leased. Of the 1,031,938 and 3,055,427 square feet of second generation leases that commenced during the three and nine months ended September 30, 2014, respectively, leases for 885,892 and 2,226,175 square feet were signed in prior periods for the three and nine months ended September 30, 2014, respectively.

(2)	Total transaction costs include tenant improvements and leasing commissions and exclude free rent concessions and other inducements in accordance with GAAP.

(3)

Represents the increase in gross rent (base rent plus expense reimbursements) on the new vs. expired leases on the 869,019 and 2,514,844 square feet of second generation leases (1) that had been occupied within the prior 12 months and (2) for which the new lease term is greater than six months for the three and nine months ended September 30, 2014, respectively.

(4)

Represents the increase in net rent (gross rent less operating expenses) on the new vs. expired leases on the 869,019 and 2,514,844 square feet of second generation leases (1) that had been occupied within the prior 12 months and (2) for which the new lease term is greater than six months for the three and nine months ended September 30, 2014, respectively.

In the aggregate from October 1, 2014 to December 31, 2015, leases representing approximately 8.2% of the space at our properties will expire. As these leases expire, assuming no change in current market rental rates, we expect that the gross rental rates we are likely to achieve on new leases will on average be greater than the rates that are currently being paid.

Although we continue to evaluate opportunities to acquire assets, the abundance of capital and demand for assets has resulted in increasing prices. As a result, in the current environment we are able to develop properties at a cost per square foot that is generally less than the cost at which we can acquire older existing properties, thereby generating relatively better returns with lower annual maintenance expenses and capital costs. Accordingly, we believe the successful lease-up and completion of our development pipeline will enhance our long-term return on equity and earnings growth as these developments are placed in-service through 2019. We believe the development of well-positioned office buildings is justified in many of our submarkets where tenants have shown demand for high-quality construction, modern design, efficient floor plates and sustainable features. In addition, select first-class residential developments that are part of a mixed-use environment, which combine office, retail and residential uses, have proven successful in our markets. As of September 30, 2014, our current development pipeline, which excludes properties which are fully placed in-service, totals approximately 3.3 million square feet with a total projected investment of approximately $2.1 billion, of which approximately $1.3 billion remains to be funded. Additionally, we are working on several new developments in each of our markets that could commence in 2015 or later.

Given investor demand for assets like ours we continue to review our portfolio to identify properties that may have limited opportunities for cash flow growth, no longer fit within our portfolio strategy or can attract premium pricing in the current market environment as potential sales candidates. During 2014, we expect to complete the sale of an aggregate of approximately $2.3 billion (our share) of assets generating $1.9 billion of sale proceeds. Included in this amount is the October 30, 2014 sale of a 45% interest in each of 601 Lexington Avenue in New York, and Atlantic Wharf Office Building and 100 Federal Street in Boston for an aggregate gross sale price of $1.827 billion in cash, less the partner’s pro rata share of indebtedness secured by 601 Lexington Avenue, subject to certain prorations and adjustments. In general, we structure asset sales for possible inclusion in like-kind exchanges within the meaning of Section 1031 of the Internal Revenue Code. The ability to complete a like-kind exchange depends on many factors, including, among others, identifying and acquiring suitable replacement property within limited time periods and the ownership structure of the properties being sold and acquired, and therefore we are not always able to sell an asset as part of a like-kind exchange. When successful, a like-kind exchange enables us to defer the taxable gain on the asset sold and thus limit our REIT distribution requirement and preserve capital. If we are unable to identify and acquire suitable replacement property in a like-kind exchange, then we expect to distribute at least the amount of proceeds necessary to avoid paying a corporate level tax on the gain realized from the sale (See “Liquidity and Capital Resources—REIT Tax Distribution Considerations—Application of Recent Regulations”).

We continue to maintain substantial liquidity, including available cash, as of November 3, 2014, of approximately $2.6 billion, which includes approximately $1.9 billion of restricted cash which is being held for possible investment in a like-kind exchange in accordance with Section 1031 of the Internal Revenue Code, and

approximately $984 million available under our Operating Partnership’s $1.0 billion Unsecured Line of Credit. Our more significant future funding requirements include approximately $1.3 billion of our development pipeline that remains to be funded through 2019, approximately $165 million (of which our share is approximately $45 million) of secured debt that matures through 2015 and the optional redemption of $550 million aggregate principal amount of unsecured senior notes on December 15, 2014 (See Note 13 of the Consolidated Financial Statements). We have access to multiple sources of capital, including current cash balances, public debt and equity markets, secured and unsecured debt markets and potential asset sales to fund our future capital requirements.

•

On October 24, 2014, we completed the sale of a parcel of land at 130 Third Avenue in Waltham, Massachusetts that is permitted for 129,000 square feet for a sale price of approximately $14.3 million, which exceeded the carrying value of the property.

•

On October 24, 2014, 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 construction loan totaled approximately $13.9 million and bore interest at a variable rate equal to LIBOR plus 1.65% per annum and was scheduled to mature on November 17, 2014. The extended loan has a total commitment amount of $16.4 million, bears interest at a variable rate equal to LIBOR plus 2.25% per annum and matures on November 17, 2015. Annapolis Junction Building Six is a Class A office property with approximately 119,000 net rentable square feet located in Annapolis, Maryland.

•

On October 30, 2014, we completed the sale of a 45% interest in each of 601 Lexington Avenue in New York City and Atlantic Wharf Office Building and 100 Federal Street in Boston for an aggregate gross sales price of approximately $1.827 billion in cash, less the partner’s pro rata share of the indebtedness secured by 601 Lexington Avenue, subject to certain prorations and adjustments. In connection with the sale, we formed a joint venture for each property with the buyer and will provide customary property management and leasing services to the joint ventures. 601 Lexington Avenue is a 1,669,000 square foot Class A office complex located in Midtown Manhattan. The property consists of a 59-story tower as well as a six-story low-rise office and retail building. The property is subject to existing mortgage indebtedness of approximately $712.9 million. The Atlantic Wharf Office Building is a 791,000 square foot Class A office tower located on Boston’s Waterfront. 100 Federal Street is a 1,323,000 square foot Class A office tower located in Boston’s Financial District. We currently expect that we will distribute at least the amount of proceeds necessary to avoid paying a corporate level tax on the gain realized from the sale. The transaction did not qualify as a sale of real estate for financial reporting purposes as we continue to control the joint ventures and will therefore continue to account for the properties on a consolidated basis in our financial statements.

•

The redemption price for each series of notes will equal the sum of (a) the present values as of the redemption date of the remaining scheduled payments of principal and interest from the redemption date to maturity (excluding any accrued and unpaid interest) discounted on a semi-annual basis at a rate equal to the yield to maturity of a comparable United States Treasury security plus (i) in the case of the 5.625% Notes, 0.35%, or (ii) in the case of the 5.00% Notes, 0.25%,

plus (b) accrued interest to, but excluding, December 15, 2014, as provided in the applicable indenture. The redemption price for each series of notes will be calculated three business days prior to the redemption date and will be payable on December 15, 2014 in accordance with the terms of the applicable indentures.

•

On November 6, 2014, we entered into an option agreement pursuant to which we have been granted an option to purchase real property located at 425 Fourth Street in San Francisco, California. In connection with the execution of the agreement, we paid a non-refundable option payment to the current owner of $1.0 million. We intend to pursue the entitlements necessary to develop the property. The purchase price has not been determined and is dependent on the entitlements obtained. There can be no assurance that we will be successful in obtaining the desired entitlements or that we will ultimately determine to exercise the option.

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 that constitutes a business, which includes the consolidation of previously unconsolidated joint ventures, 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 and consider 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.

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 an impairment in value. An impairment loss is recognized if the carrying amount of its assets is not recoverable and exceeds its fair value. If such criteria are present, an impairment loss is recognized based on the excess of the carrying amount of the asset over its fair value. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. Since 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 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, less cost to sell.

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. The components of the property’s net income that is 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 our 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. On April 10, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” (“ASU No. 2014-08”). ASU No. 2014-08 clarifies that 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). ASU No. 2014-08 is effective prospectively for reporting periods beginning after December 15, 2014. Early adoption is permitted, and we early adopted ASU No. 2014-08 during the first quarter of 2014. Our adoption of ASU No. 2014-08 did not have a material impact on our consolidated financial statements.

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 expense costs that we incur to effect a business combination such as 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 a project that is benefited. 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 is guided by 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.

The 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 to the development of the property. We consider a

construction project as substantially completed 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 completed, (2) occupied or held available for occupancy, and we 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 a controlling financial interest. 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 right to receive the returns from the variable interest entity that would be significant to the variable interest entity. 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 non-controlling 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. 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 values has occurred and such decline is other-than-temporary. 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 value below the carrying value 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

970-323 “Investments-Equity Method and Joint Ventures” (“ASC 970-323”), we will recognize gains on the contribution of real estate to joint ventures, relating solely to the outside partner’s interest, to the extent the economic substance of the transaction is a sale.

The combined summarized financial information of the unconsolidated joint ventures is disclosed in Note 4 to the Consolidated Financial Statements.

Revenue Recognition

In general, we commence rental revenue recognition when the tenant takes possession of the leased space and the leased space is substantially ready for its intended use. Contractual rental revenue is reported on a straight-line basis over the terms of our respective leases. We recognize rental revenue of acquired in-place “above-” and “below-market” leases at their fair values over the original term of the respective leases. Accrued rental income as reported on the Consolidated Balance Sheets represents rental income recognized in excess of rent payments actually received pursuant to the terms of the individual lease agreements.

For the three and nine months ended September 30, 2014, the impact of the net adjustments of rents from “above-” and “below-market” leases increased rental revenue by approximately $11.5 million and $30.7 million, respectively. For the three and nine months ended September 30, 2014, the impact of the straight-line rent adjustment increased rental revenue by approximately $19.9 million and $41.8 million, respectively. 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 4 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 consistently monitor the credit quality of our tenant base. We provide an allowance for doubtful accounts arising from estimated losses that could result from the tenant’s inability to make required current rent payments and an allowance against accrued rental income for future potential losses that we deem to be unrecoverable over the term of the lease.

Tenant receivables are assigned a credit rating of 1 through 4. A rating of 1 represents the highest possible rating and no allowance is recorded. A rating of 4 represents the lowest credit rating, in which case we record a full reserve against the receivable balance. Among the factors considered in determining the credit rating include:

•

payment history;

•

credit status and change in status (credit ratings for public companies are used as a primary metric);

•

change in tenant space needs (i.e., expansion/downsize);

•

tenant financial performance;

•

economic conditions in a specific geographic region; and

•

industry specific credit considerations.

If our estimates of collectability differ from the cash received, the timing and amount of our reported revenue could be impacted. The average remaining term of our in-place tenant leases, including unconsolidated joint ventures, was approximately 6.8 years as of September 30, 2014. 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. Tenant reimbursements are recognized and presented in accordance with guidance in ASC 605-45 “Principal Agent Considerations” (“ASC 605-45”). ASC 605-45 requires that these reimbursements be recorded on a gross basis, as we are generally the primary obligor with respect to purchasing goods and services from third-party suppliers, have discretion in selecting the supplier and have credit risk. We also receive reimbursement of payroll and payroll related costs from third parties which we reflect on a net basis.

Our parking revenues are derived from leases, monthly parking and transient parking. We recognize parking revenue as earned.

Our hotel revenues are 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 revenues are recognized as earned.

We receive management and development fees from third parties. 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. We review each development agreement and record development fees as earned depending on the risk associated with each project. Profit on development fees earned from joint venture projects is recognized as revenue to the extent of the third-party partners’ ownership interest.

Gains on sales of real estate are recognized pursuant to the provisions included in ASC 360-20 “Real Estate Sales” (“ASC 360-20”). The specific timing of the sale is measured against various criteria in ASC 360-20 related to the terms of the transaction and any continuing involvement in the form of management or financial assistance associated with the properties. If the sales criteria for the full accrual method are not met, we defer some or all of the gain recognition and account for the continued operations of the property by applying the finance, leasing, profit sharing, deposit, installment or cost recovery methods, as appropriate, until the sales criteria are 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 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. We determine the fair value of our unsecured senior notes and unsecured exchangeable senior notes using market prices. The inputs used in determining the fair value of our unsecured senior notes and unsecured exchangeable senior notes is categorized at a level 1 basis (as defined in the accounting standards for Fair Value Measurements and Disclosures) due to the fact that we use quoted market rates to value these instruments. However, the inputs used in determining the fair value could be categorized at a level 2 basis if trading volumes are low. We determine the fair value of our mortgage notes payable using discounted cash flow analyses by discounting the spread between the future contractual interest payments and hypothetical future interest payments on 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 mortgage notes payable and mezzanine notes payable are categorized at a level 3 basis (as defined in the accounting standards for Fair Value Measurements and Disclosures) due to the fact that we consider the rates used in the valuation techniques to be unobservable inputs.

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 the effective portion of changes in the fair value of a derivative in other comprehensive income (loss) and subsequently reclassify the effective portion to earnings over the term that the hedged transaction affects earnings. We account for the ineffective portion of changes in the fair value of a derivative directly in earnings.

Recent Accounting Pronouncements

periods (including interim periods within that reporting period) beginning after December 15, 2016 and shall be applied using either a full retrospective or modified retrospective approach. Early adoption is not permitted. We are currently assessing the potential impact that the adoption of ASU 2014-09 will have on our consolidated financial statements.

In June 2014, the FASB issued ASU No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (“ASU 2014-12”). The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in ASC Topic No. 718, “Compensation—Stock Compensation” (“ASC 718”), as it relates to awards with performance conditions that affect vesting to account for such awards. The amendments in ASU 2014-12 are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in ASU 2014-12 either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. We do not expect the adoption of ASU 2014-12 to have a material impact on our consolidated financial statements.

In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements—Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU 2014-15”). ASU 2014-15 requires an entity to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the financial statements are available to be issued when applicable) and to provide related footnote disclosures in certain circumstances. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter with early adoption permitted. We do not expect the adoption of ASU 2014-15 to have a material impact on our consolidated financial statements.

Results of Operations

The following discussion is based on our Consolidated Statements of Operations for the three and nine months ended September 30, 2014 and 2013.

At September 30, 2014 and September 30, 2013, we owned or had interests in a portfolio of 172 and 177 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 is necessarily meaningful. Therefore, the comparison of operating results for the three and nine months ended September 30, 2014 and 2013 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 or Consolidated, 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 consolidated 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 consolidated 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, or “NOI,” is a non-GAAP financial measure equal to net income attributable to Boston Properties, Inc., the most directly comparable GAAP financial measure, plus income attributable to

noncontrolling interests, depreciation and amortization, interest expense, impairment loss, transaction costs, general and administrative expense, less gains on sales of real estate, discontinued operations, gains (losses) from early extinguishments of debt, gains (losses) from investments in securities, gains on consolidation of joint ventures, income from unconsolidated joint ventures, interest and other income and development and management services revenue. We use NOI internally as a performance measure and believe NOI provides useful information to investors regarding our financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level. Therefore, we believe NOI is a useful measure for evaluating the operating performance of our real estate assets.

Our management also uses NOI to evaluate regional property level performance and to make decisions about resource allocations. Further, we believe NOI is useful to investors as a performance measure because, when compared across periods, NOI reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and development activity on an unleveraged basis, providing perspectives not immediately apparent from net income attributable to Boston Properties, Inc. NOI excludes certain components from net income attributable to Boston Properties, Inc. in order to provide results that are more closely related to a property’s results of operations. 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. In addition, depreciation and amortization, because of historical cost accounting and useful life estimates, may distort operating performance at the property level. NOI presented by us may not be comparable to NOI reported by other REITs 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. as presented in our Consolidated Financial Statements. NOI should not be considered as an alternative to net income attributable to Boston Properties, Inc. as an indication of our performance or to cash flows as a measure of liquidity or ability to make distributions. For a reconciliation of NOI to net income attributable to Boston Properties, Inc., see Note 12 to the Consolidated Financial Statements.

Comparison of the nine months ended September 30, 2014 to the nine months ended September 30, 2013.

The table below shows selected operating information for the Same Property Portfolio and the Total Property Portfolio. The Same Property Portfolio consists of 132 properties totaling approximately 35.9 million net rentable square feet of space, excluding unconsolidated joint ventures. The Same Property Portfolio includes properties acquired or consolidated or placed in-service on or prior to January 1, 2013 and owned and in service through September 30, 2014. The Total Property Portfolio includes the effects of the other properties either placed in-service, acquired or consolidated or in development or redevelopment after January 1, 2013 or disposed of on or prior to September 30, 2014. This table includes a reconciliation from the Same Property Portfolio to the Total Property Portfolio by also providing information for the nine months ended September 30, 2014 and 2013 with respect to the properties that were placed in-service, acquired or consolidated, in development or redevelopment or sold.

Residential Net Operating Income for the nine months ended September 30, 2014 and 2013 are comprised of Residential Revenue of $18,998 and $16,555 less Residential Expenses of $11,861 and $8,470, respectively. Hotel Net Operating Income for the nine months ended September 30, 2014 and 2013 are comprised of Hotel Revenue of $32,478 and $30,061 less Hotel Expenses of $21,697 and $20,959, respectively, per the Consolidated Statements of Operations.

Same Property Portfolio

Rental Revenue

Rental revenue from the Same Property Portfolio increased approximately $51.6 million for the nine months ended September 30, 2014 compared to 2013. The increase was primarily the result of increases in revenue from our leases, parking income and other income and recoveries of approximately $48.0 million, $3.5 million and $0.1 million, respectively. Rental revenue from our leases increased approximately $48.0 million as a result of our average revenue per square foot increasing by approximately $1.44, contributing approximately $35.2 million, and an approximately $12.8 million increase due to an increase in average occupancy from 92.0% to 92.8%.

For fiscal 2014, we expect an increase in Same Property Portfolio net operating income of approximately 3.0% to 3.25% compared to 2013 and for fiscal 2015, we expect our occupancy to decline to approximately 91%-92% due primarily to several lease expirations in our Boston region, resulting in 2015 Same Property Portfolio net operating income to be relatively flat at approximately (1.0)% to 0.50% compared to 2014.

Termination Income

Termination income increased by approximately $8.1 million for the nine months ended September 30, 2014 compared to 2013.

Termination income for the nine months ended September 30, 2014 related to twenty-one tenants across the Same Property Portfolio and totaled approximately $10.3 million of which approximately $7.7 million related to an initial distribution we received from our unsecured creditor claim against Lehman Brothers, Inc. (See Note 7 of the Consolidated Financial Statements).

Termination income for the nine months ended September 30, 2013 related to nineteen tenants across the Same Property Portfolio and totaled approximately $2.1 million of which approximately $1.0 million was negotiated termination income from one of our Reston, Virginia properties in order to accommodate growth of another existing tenant.

Real Estate Operating Expenses

Operating expenses from the Same Property Portfolio increased approximately $23.5 million for the nine months ended September 30, 2014 compared to 2013 due primarily to (1) an increase of approximately $11.2 million, or 5.1%, in real estate taxes, which we primarily experienced in our Washington, DC and New York regions, (2) an increase of approximately $7.2 million, or 9.3%, in repairs and maintenance expense, which we primarily experienced in the Boston and New York CBD buildings and the Washington, DC region, (3) an increase of approximately $2.6 million, or 9.6%, in roads and grounds expense, which we primarily experienced in the Boston and Washington, DC regions and (4) an increase of approximately $2.5 million, or 1.5%, in other operating expenses.

Depreciation and Amortization Expense

Depreciation and amortization expense for the Same Property Portfolio increased approximately $3.6 million, or 1.0%, for the nine months ended September 30, 2014 compared to 2013.

Properties Acquired or Consolidated Portfolio

On April 10, 2013, we acquired the Mountain View Research Park and Mountain View Technology Park properties from the Value-Added Fund for an aggregate net purchase price of approximately $233.1 million. Prior to the acquisition, our ownership interest in the properties was approximately 39.5%. As a result of the acquisition, we own 100% of the properties and account for them on a consolidated basis. Mountain View

Research Park is an approximately 604,000 net rentable square foot, sixteen building Office/Technical complex. Mountain View Technology Park is an approximately 135,000 net rentable square foot, seven building Office/Technical complex. On July 29, 2014, we sold Mountain View Technology Park and Mountain View Research Park Building Sixteen, which in aggregate is approximately 198,000 square feet. See Note 3 to the Consolidated Financial Statements and “Results of Operations—Properties Sold Portfolio” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

On May 31, 2013, our two joint venture partners in 767 Venture, LLC (the entity that owns 767 Fifth Avenue (the General Motors Building) in New York City) transferred all of their interests in the joint venture to third parties. In connection with the transfer, we and our new joint venture partners modified our relative decision making authority and consent rights with respect to the joint venture’s assets and operations. These changes resulted in us having sufficient financial and operating control over 767 Venture, LLC such that we now account for the assets, liabilities and operations of 767 Venture, LLC on a consolidated basis in our financial statements instead of under the equity method of accounting. Our ownership interest in 767 Venture, LLC remained unchanged at 60%. 767 Fifth Avenue (the General Motors Building) is an approximately 1.8 million net rentable square foot, 59-story Class A office tower.

Depreciation and Amortization Expense

Depreciation and amortization expense for our Properties Acquired or Consolidated Portfolio increased by approximately $49.4 million for the nine months ended September 30, 2014 compared to 2013 due to the additional depreciation expense incurred for the nine months ended September 30, 2014 associated with Mountain View Research Park that was acquired on April 10, 2013 and 767 Fifth Avenue (the General Motors Building) that was consolidated on May 31, 2013, and, as a result, were not recognizing depreciation expense for the full nine months ended September 30, 2013.

Properties Placed In-Service Portfolio

We placed in-service or partially placed in-service seven properties between January 1, 2013 and September 30, 2014. The square footage amount for the seven properties that are fully placed in-service is approximately 2.6 million square feet. One and Two Patriots Park comprise of a two-phase redevelopment project for a single tenant. On October 2, 2014, we completed the sale of our Patriots Park properties located in Reston, Virginia (See Note 13 of the Consolidated Financial Statements).

Depreciation and Amortization Expense

Depreciation and amortization expense for our Properties Placed In-Service Portfolio increased by approximately $11.2 million for the nine months ended September 30, 2014 compared to 2013 due to the additional depreciation expense incurred for the nine months ended September 30, 2014 associated with One and Two Patriots Park, 300 Binney Street (formerly Seventeen Cambridge Center), 250 West 55th Street, 680 Folsom Street and The Avant at Reston Town Center that were all fully or partially placed in-service during or subsequent to the nine months ended September 30, 2013, and, as a result, we were not recognizing depreciation expense for the full nine months ended September 30, 2013.

Properties in Development or Redevelopment Portfolio

During the nine months ended September 30, 2013, the Properties in Development or Redevelopment Portfolio consisted of our 601 Massachusetts Avenue property located in Washington, DC. We commenced development of this property on April 25, 2013 and it is expected to be completed during the fourth quarter of 2015. Prior to the commencement of development, this building was operational and during the nine months ended September 30, 2013, had approximately $2.2 million of revenue and approximately $0.4 million of operating expenses. In addition, during the nine months ended September 30, 2013, the building had approximately $4.6 million of depreciation and amortization expense.

Properties Sold Portfolio

Rental Revenue

Rental revenue from our Properties Sold Portfolio increased approximately $756,000 for the nine months ended September 30, 2014 compared to 2013, as detailed below:


Property	Date Sold	Rental Revenue for the nine months ended September 30,

Total		$	931	$	800	$	131

Depreciation and Amortization Expense

Depreciation and amortization expense for our Properties Sold Portfolio increased by approximately $385,000 for the nine months ended September 30, 2014 compared to 2013. On April 10, 2013, we acquired the Mountain View Research Park, which included Mountain View Research Park Building Sixteen and Mountain View Technology Park properties from the Value-Added Fund and therefore we did not have depreciation and amortization expense for the entire nine month period ended September 30, 2013. Subsequently, we sold Mountain View Technology Park and Mountain View Research Park Building Sixteen on July 29, 2014 and therefore did not have depreciation and amortization expense for the entire nine month period ended September 30, 2014. As a result, the increase is primarily due to the fact that we owned those properties for a longer period in 2014 compared to 2013.

Other Operating Income and Expense Items

Residential Net Operating Income

Net operating income for our residential properties decreased by approximately $0.9 million for the nine months ended September 30, 2014 compared to 2013.

The following reflects our occupancy and rate information for The Lofts at Atlantic Wharf, the Residences on The Avenue and The Avant at Reston Town Center for the nine months ended September 30, 2014 and 2013.

This property was initially placed in-service during the fourth quarter of 2013 and fully placed in-service during the first quarter of 2014. For the operating results refer to “Results of Operations—Properties Placed in-Service Portfolio” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

(2)	Average Physical Occupancy is defined as the average number of occupied units divided by the total number of units, expressed as a percentage.

(3)

Average Economic Occupancy is defined as total possible revenue less vacancy loss as a percentage of total possible revenue. 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.

(4)	Average Monthly Rental Rates are calculated by us as rental revenue in accordance with GAAP, divided by the weighted monthly average number of occupied units.

Hotel Net Operating Income

Net operating income for the Boston Marriott Cambridge (formerly Cambridge Center Marriott) hotel property increased by approximately $1.7 million for the nine months ended September 30, 2014 compared to 2013. We expect our hotel net operating income for fiscal 2014 to be between $13 million and $14 million and between $12 million and $14 million for fiscal 2015.

The following reflects our occupancy and rate information for the Boston Marriott Cambridge (formerly Cambridge Center Marriott) hotel for the nine months ended September 30, 2014 and 2013.


	2014			2013			Percentage Change
Occupancy		84.1	%		81.3	%		3.4	%
Average daily rate	$	249.98		$	229.40			9.0	%
Revenue per available room, REVPAR	$	210.27		$	207.60			1.3	%

Development and Management Services

Development and management services income decreased approximately $3.9 million for the nine months ended September 30, 2014 compared to 2013. The decrease was due to decreases in development fee and management fee income of approximately $0.5 million and $3.4 million, respectively. The decrease in development fees is primarily due to a decrease in fees associated with tenant improvement project management partially offset by an increase in the development fees earned from our current and pending development projects in the Boston and Washington, DC regions. The decrease in management fees is due primarily to a decrease in management and leasing fees earned from our joint ventures primarily due to the consolidation of 767 Fifth Avenue (the General Motors Building), the acquisition of the Mountain View assets and the sale of 125 West 55th Street. We expect fee income for fiscal 2014 to be between $22 million and $25 million. In addition, we

expect fee income for fiscal 2015 to be between $15 million and $20 million. Our 2015 estimates are less than 2014 due to the completion of several large, third-party development fee projects in 2014, including the Broad Institute expansion in Cambridge, Massachusetts and the George Washington University Science Center in Washington, DC and we have been focusing our resources on our development pipeline and delivering our new projects as opposed to third-party assignments.

General and Administrative

General and administrative expenses decreased approximately $18.9 million for the nine months ended September 30, 2014 compared to 2013 due primarily to the timing of the recognition of expenses under the Transition Benefits Agreement that we entered into with Mortimer B. Zuckerman in 2013. On March 11, 2013, we announced that Owen D. Thomas would succeed Mr. Zuckerman as our Chief Executive Officer, effective April 2, 2013. Mr. Zuckerman continues to serve as Executive Chairman for a transition period and thereafter is expected to continue to serve as the Non-Executive Chairman of the Board. In connection with succession planning, Mr. Zuckerman entered into the Transition Benefits Agreement with us. Because Mr. Zuckerman remained employed by us through July 1, 2014, he is entitled to receive, on January 1, 2015, a lump sum cash payment of $6.7 million and an equity award with a targeted value of approximately $11.1 million. The cash payment and equity award vested in three equal installments on each of March 10, 2013, October 1, 2013 and July 1, 2014. As a result, we recognized approximately $11.8 million of compensation expense during the nine months ended September 30, 2013 and approximately $4.0 million of compensation expense during the nine months ended September 30, 2014 related to the Transition Benefits Agreement. Under the Transition Benefits Agreement, during the nine months ended September 30, 2013, we accelerated the remaining approximately $12.9 million of stock-based compensation expense associated with Mr. Zuckerman’s unvested long-term equity awards. In addition, for the nine months ended September 30, 2014 compared to 2013 we had an approximately $2.3 million increase in our capitalized wages due to the signing of several large leases. The increase in capitalized wages is shown as a decrease in general and administrative expenses as these costs are capitalized and included in real estate assets or deferred charges on our Consolidated Balance Sheets (see below). We also had an approximately $1.2 million decrease in the value of our deferred compensation plan. These decreases were partially offset by the following increases: (1) approximately $2.6 million related to the net effect of the termination of the 2011 OPP Awards and the issuance of the 2014 MYLTIP Units (See Note 11 to the Consolidated Financial Statements), (2) approximately $0.3 million related to the write off of the remaining fees associated with our ATM program that expired on June 2, 2014 and (3) approximately $2.4 million related to other general and administrative expenses, which includes compensation expense. We expect our fiscal 2014 general and administrative expenses to be between $100 million and $102 million and between $100 million and $104 million in fiscal 2015.

Wages directly related to the development and leasing of rental properties are not included in our operating results. These costs are capitalized and included in real estate assets or deferred charges on our Consolidated Balance Sheets and amortized over the useful lives of the real estate. Capitalized wages for the nine months ended September 30, 2014 and 2013 were approximately $11.0 million and $8.7 million, respectively. These costs are not included in the general and administrative expenses discussed above.

Transaction Costs

During the nine months ended September 30, 2014, we incurred approximately $2.5 million of transaction costs, which related to (1) approximately $0.5 million for the pending sale of Patriots Park in Reston, Virginia (See Note 13 to the Consolidated Financial Statements), (2) approximately $0.5 million related to transactions that we are no longer pursuing in the Washington, DC region, (3) approximately $0.3 million for the formation of the joint venture agreement to sell to a third-party a 45% interest in each of 601 Lexington Avenue in New York City and Atlantic Wharf Office Building and 100 Federal Street in Boston, Massachusetts (See Note 13 to the Consolidated Financial Statements) and (4) approximately $1.2 million related to the pursuit or sale of other assets and the formation of joint venture agreements.

During the nine months ended September 30, 2013, we incurred approximately $1.7 million of transaction costs related to (1) approximately $0.6 million related to the acquisition of the Mountain View Research Park and Mountain View Technology Park properties in Mountain View, California, (2) approximately $0.4 million related to Salesforce Tower (formerly Transbay Tower) in San Francisco, California, (3) approximately $0.5 million related to transaction costs for transactions in New York City and (4) approximately $0.2 million related to the pursuit of other transactions.

Impairment Loss

On March 28, 2013, we executed a binding contract for the sale of our 303 Almaden Boulevard property located in San Jose, California for a sale price of $40.0 million. The pending sale of this asset caused us to evaluate our strategy for development of the adjacent Almaden land parcel which can accommodate approximately 840,000 square feet of office development. Based on a shorter than expected hold period, we reduced the carrying value of the land parcel to its estimated fair market value and we recognized an impairment loss of approximately $8.3 million during the three months ended March 31, 2013. We did not recognize any impairment losses during the nine months ended September 30, 2014.

Other Income and Expense Items

Income from Unconsolidated Joint Ventures

For the nine months ended September 30, 2014 compared to 2013, income from unconsolidated joint ventures decreased by approximately $62.2 million due primarily to an approximately $46.5 million decrease in our share of net income from 125 West 55th Street due to its sale on May 30, 2013, an approximately $11.2 million decrease in our share of net income from the sale of the Eighth Avenue and 46th Street project in New York City on July 19, 2013 and an approximately $7.7 million decrease in our share of net income from 767 Fifth Avenue (the General Motors Building) related to its consolidation on June 1, 2013. These decreases were partially offset by an approximately $3.2 million increase in our share of net income from our other unconsolidated joint ventures, which was primarily related to increased leasing and occupancy at 540 Madison Avenue in New York City.

On May 30, 2013, a joint venture in which we have a 60% interest completed the sale of its 125 West 55th Street property located in New York City for a sale price of $470.0 million, including the assumption by the buyer of the mortgage loan collateralized by the property totaling approximately $198.6 million. The mortgage loan bore interest at a fixed rate of 6.09% per annum and was scheduled to mature on March 10, 2020. Net cash proceeds totaled approximately $253.7 million, of which our share was approximately $152.2 million, after the payment of transaction costs. 125 West 55th Street is a Class A office property totaling approximately 588,000 net rentable square feet. We had previously recognized an impairment loss on our investment in the unconsolidated joint venture. As a result, we recognized a gain on sale of real estate totaling approximately $43.2 million. Prior to the sale, the property contributed approximately $3.3 million of net income for the nine months ended September 30, 2013.

On July 19, 2013, a joint venture in which we have a 50% interest completed the sale of its Eighth Avenue and 46th Street project located in New York City for an imputed sale price of $45.0 million. Eighth Avenue and 46th Street is comprised of an assemblage of land parcels and air-rights. Net cash proceeds to us totaled approximately $21.8 million, after the payment of transaction costs. The joint venture had previously recognized an impairment loss on the property. As a result, the joint venture recognized a gain on sale of real estate totaling approximately $12.6 million, of which our share was approximately $11.3 million.

For the consolidated operating results for 767 Fifth Avenue (the General Motors Building), Mountain View Research Park and Mountain View Technology Park refer to “Results of Operations—Properties Acquired or Consolidated Portfolio” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Gains on Consolidation of Joint Ventures

On April 10, 2013, we acquired the Mountain View Research Park and Mountain View Technology Park properties from our Value-Added Fund for an aggregate purchase price of approximately $233.5 million. Prior to the acquisition, our ownership interest in the properties was approximately 39.5%. As a result of the acquisition, we own 100% of the properties and account for them on a consolidated basis. During the nine months ended September 30, 2013, we recognized a gain on consolidation totaling approximately $26.5 million.

On May 31, 2013, our two joint venture partners in 767 Venture, LLC (the entity that owns 767 Fifth Avenue in New York City) transferred all of their interests in the joint venture to third parties. In connection with the transfer, we and our new joint venture partners modified our relative decision making authority and consent rights with respect to the joint venture’s assets and operations. These changes resulted in us having sufficient financial and operating control over 767 Venture, LLC such that we now account for the assets, liabilities and operations of 767 Venture, LLC on a consolidated basis in our financial statements instead of under the equity method of accounting. Our ownership interest in 767 Venture, LLC remained unchanged at 60%. During the nine months ended September 30, 2013, we recognized a non-cash gain on our investment of approximately $359.5 million. The gain on consolidation resulted from us recognizing the assets, liabilities and equity (including noncontrolling interests) of the joint venture at fair value on the date of consolidation resulting in the recognition of a gain on consolidation equal to the difference between the fair value of our equity interest totaling approximately $721.3 million (as reflected in the business combination table appearing on pages 132 and 133 of the Company’s Form 10-K for the fiscal year ended December 31, 2013) and the carrying value of our previously held equity interest totaling approximately $361.8 million. The fair value was determined based on the purchase price paid by the new joint venture partners through a sales process managed by a major New York City sales brokerage firm.

Interest and Other Income

Interest and other income increased approximately $0.2 million for the nine months ended September 30, 2014 compared to 2013 primarily due to a tax refund we received from the District of Columbia partially offset by a decrease in interest income due to lower average cash balances and interest rates.

Gains from Investments in Securities

Gains from investments in securities for the nine months ended September 30, 2014 and 2013 related to investments that we have made to reduce our market risk relating to a deferred compensation plan that we maintain for our officers. Under this deferred compensation plan, each officer who is eligible to participate is permitted 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. In order to reduce our market risk relating to this plan, 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. This enables us to generally match our liabilities to our officers under the deferred compensation plan with equivalent assets and thereby limit our market risk. The performance of these investments is recorded as gains from investments in securities. During the nine months ended September 30, 2014 and 2013, we recognized gains of approximately $0.7 million and $1.9 million, respectively, on these investments. By comparison, our general and administrative expense increased by approximately $0.7 million and $1.9 million during the nine months ended September 30, 2014 and 2013, respectively, as a result of increases in our liability under our deferred compensation plan that were associated with the performance of the specific investments selected by our officers participating in the plan.

Gains from Early Extinguishments of Debt

On April 1, 2013, we used available cash to repay the mortgage loan collateralized by our 140 Kendrick Street property located in Needham, Massachusetts totaling approximately $47.6 million. The mortgage loan

bore interest at a fixed rate of 7.51% per annum and was scheduled to mature on July 1, 2013. There was no prepayment penalty. We recognized a gain on early extinguishment of debt totaling approximately $0.3 million related to the acceleration of the remaining balance of the historical fair value debt adjustment, which was the result of purchase accounting.

On April 15, 2013, we announced that holders of our Operating Partnership’s 3.75% Exchangeable Senior Notes due 2036 (the “Notes”) had the right to surrender their Notes for purchase by our Operating Partnership (the “Put Right”) on May 18, 2013. On April 15, 2013, we also announced that our Operating Partnership issued a notice of redemption to the holders of the Notes to redeem, on May 18, 2013 (the “Redemption Date”), all of the Notes outstanding on the Redemption Date. In connection with the notice of redemption, holders of the Notes had the right to exchange their Notes on or prior to May 16, 2013. Notes with respect to which the Put Right was not exercised and that were not surrendered for exchange on or prior to May 16, 2013, were redeemed by our Operating Partnership at a redemption price equal to 100% of the principal amount of the Notes plus accrued and unpaid interest thereon to, but excluding, the Redemption Date. Based on final information provided to our Operating Partnership by the trustee for the Notes, no Notes were validly tendered and accepted for purchase in the Put Right. Pursuant to the notice of redemption, an aggregate principal amount of $990,000 of the Notes was redeemed on May 18, 2013. The remaining aggregate principal amount of $449,010,000 of the Notes was surrendered for exchange and, in addition to the repayment of the principal in cash, we issued an aggregate of 419,116 shares of our common stock in exchange for the Notes. We recognized a loss on early extinguishment of debt totaling approximately $0.1 million consisting of transaction costs.

Interest Expense

Interest expense increased approximately $12.1 million for the nine months ended September 30, 2014 compared to 2013 as detailed below:


Component	Change in interest expense for the nine months ended September 30, 2014 compared to September 30, 2013
	(in thousands)
Increases to interest expense due to:
Interest associated with the consolidation of the $1.6 billion of debt outstanding for 767 Fifth Avenue (the General Motors Building)	$	21,265
Issuance of $700 million in aggregate principal of our Operating Partnership’s 3.800% senior notes due 2024 on June 27, 2013		13,134

Total decreases to interest expense	$	(43,990	)

Total change in interest expense	$	12,093

(1)	Includes the repayment of Kingstowne One, 140 Kendrick Street and New Dominion Technology Park Building Two.

Interest expense directly related to the development of rental properties is not included in our operating results. These costs are capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over the useful lives of the real estate. As properties are placed in-service, we cease capitalizing interest and interest is then expensed. Interest capitalized for the nine months ended September 30, 2014 and 2013 was approximately $44.8 million and $50.3 million, respectively. These costs are not included in the interest expense referenced above.

We anticipate net interest expense for 2014 will be approximately $456 million to $459 million. This estimate assumes approximately $53 million to $55 million of capitalized interest and approximately $10 million of incremental interest expense related to the optional redemption in December 2014 of $550 million aggregate principal amount of our Operating Partnership’s unsecured senior notes that were scheduled to mature in 2015. We anticipate net interest expense for 2015 will be approximately $415 million to $425 million. This estimate assumes approximately $40 million to $50 million of capitalized interest. These estimates also assume that we will not incur any additional indebtedness, make additional prepayments or repurchases of existing indebtedness and that there will not be any fluctuations in interest rates or any changes in our development activity.

At September 30, 2014, our variable rate debt consisted of our Operating Partnership’s $1.0 billion Unsecured Line of Credit. For a summary of our consolidated debt as of September 30, 2014 and September 30, 2013 refer to the heading “Liquidity and Capital Resources—Capitalization—Debt Financing” within “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Discontinued Operations

On April 10, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” (“ASU No. 2014-08”). ASU No. 2014-08 clarifies that 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). ASU No. 2014-08 is effective prospectively for reporting periods beginning after December 15, 2014. Early adoption is permitted, and we early adopted ASU No. 2014-08 during the first quarter of 2014. Our adoption of ASU No. 2014-08 did not have a material impact on our consolidated financial statements.

Prior to the adoption of ASU No. 2014-08, we had the following properties that were considered discontinued operations for the nine months ended September 30, 2013: 10 & 20 Burlington Mall Road, One Preserve Parkway, 1301 New York Avenue, 303 Almaden Boulevard and Montvale Center. Each of these dispositions is discussed below.

On December 20, 2013, we completed the sale of our 10 & 20 Burlington Mall Road property located in Burlington, Massachusetts for a sale price of approximately $30.0 million. 10 & 20 Burlington Mall Road consists of two Class A office properties aggregating approximately 152,000 net rentable square feet. The operating results of the properties through the date of sale have been classified as discontinued operations on a historical basis for all periods presented.

On December 20, 2013, we completed the sale of our One Preserve Parkway property located in Rockville, Maryland for a sale price of approximately $61.3 million. One Preserve Parkway is a Class A office property totaling approximately 184,000 net rentable square feet. The operating results of the property through the date of sale have been classified as discontinued operations on a historical basis for all periods presented.

On August 22, 2013, we completed the sale of our 1301 New York Avenue property located in Washington, DC for a net contract sale price of approximately $121.7 million. After adjusting for outstanding lease and other transaction costs assumed by the buyer, the gross sale price was approximately $135.0 million. Net cash proceeds totaled approximately $121.5 million, resulting in a gain on sale of approximately $86.4 million. 1301 New York Avenue is a Class A office property totaling approximately 201,000 net rentable square feet. The operating results of the property through the date of sale have been classified as discontinued operations on a historical basis for all periods presented.

On June 28, 2013, we completed the sale of our 303 Almaden Boulevard property located in San Jose, California for a sale price of $40.0 million. 303 Almaden Boulevard is a Class A office property totaling approximately 158,000 net rentable square feet. Because we entered into the related purchase and sale agreement on March 28, 2013 and the carrying value of the property exceeded its net sale price, we recognized an impairment loss totaling approximately $3.2 million during the three months ended March 31, 2013. As a result, there was no loss on sale of real estate recognized. The impairment loss and operating results of this property have been classified as discontinued operations on a historical basis for all periods presented.

On February 20, 2013, the foreclosure sale of our Montvale Center property was ratified by the court. As a result of the ratification, the mortgage loan totaling $25.0 million was extinguished and the related obligations were satisfied with the transfer of the real estate resulting in the recognition of a gain on forgiveness of debt totaling approximately $20.2 million during the first quarter of 2013. The operating results of the property through the date of ratification have been classified as discontinued operations on a historical basis for all periods presented.

Gains on Sales of Real Estate

Noncontrolling interests in property partnerships

Noncontrolling interests in property partnerships increased by approximately $18.4 million for the nine months ended September 30, 2014 compared to 2013 as detailed below.


Property	Date of Consolidation	Partners’ noncontrolling interest for the nine months ended September 30,
Property	Date of Consolidation	2014			2013			Change
		(in thousands)
505 9th Street	October 1, 2007	$	1,739		$	1,853		$	(114	)
Fountain Square	October 4, 2012		8,796			5,026			3,770
767 Fifth Avenue (the General Motors Building)	May 31, 2013		(12,957	)		(7,803	)		(5,154	)
Times Square Tower	October 9, 2013		19,895			—			19,895

		$	17,473		$	(924	)	$	18,397

The decrease at 767 Fifth Avenue (the General Motors Building) was primarily due to the partners’ share of the interest expense for the outside members’ notes payable. In addition, during the nine months ended September 30, 2014 we made an out-of-period adjustment for our Fountain Square property of approximately $1.9 million related to the cumulative non-cash adjustment to the accretion of the changes in the redemption value of the noncontrolling interest (See Note 2 to the Consolidated Financial Statements).

Noncontrolling interest—Common Units of the Operating Partnership

Noncontrolling interest-common units of the Operating Partnership decreased by approximately $33.1 million for the nine months ended September 30, 2014 compared to 2013 due to a decrease in allocable income partially offset by an increase in the noncontrolling interest’s ownership percentage.

Comparison of the three months ended September 30, 2014 to the three months ended September 30, 2013.

The table below shows selected operating information for the Same Property Portfolio and the Total Property Portfolio. The Same Property Portfolio consists of 151 properties totaling approximately 39.0 million net rentable square feet of space, excluding unconsolidated joint ventures. The Same Property Portfolio includes properties acquired or consolidated or placed in-service on or prior to July 1, 2013 and owned and in service through September 30, 2014. The Total Property Portfolio includes the effects of the other properties either placed in-service, acquired or consolidated or in development or redevelopment after July 1, 2013 or disposed of on or prior to September 30, 2014. This table includes a reconciliation from the Same Property Portfolio to the Total Property Portfolio by also providing information for the three months ended September 30, 2014 and 2013 with respect to the properties that were placed in-service, acquired or consolidated, in development or redevelopment or sold.

Same Property Portfolio

Rental Revenue

Rental revenue from the Same Property Portfolio increased approximately $23.9 million for the three months ended September 30, 2014 compared to 2013. The increase was primarily the result of an increase of approximately $22.3 million in revenue from our leases, an increase in parking income of approximately $0.8 million and an increase in other income and recoveries of approximately $0.8 million. Rental revenue from our leases increased approximately $22.3 million as a result of our average revenue per square foot increasing by approximately $2.44, contributing approximately $21.6 million, and an approximately $0.7 million increase due to an increase in average occupancy from 92.7% to 92.8%.

Termination Income

Termination income increased by approximately $6.8 million for the three months ended September 30, 2014 compared to 2013.

Termination income for the three months ended September 30, 2014 related to nine tenants across the Same Property Portfolio and totaled approximately $8.2 million of which approximately $7.7 million related to an initial distribution we received from our unsecured creditor claim against Lehman Brothers, Inc. (See Note 7 of the Consolidated Financial Statements).

Termination income for the three months ended September 30, 2013 related to twelve tenants across the Same Property Portfolio and totaled approximately $1.4 million, of which approximately $1.0 million was negotiated termination income from one of our Reston, Virginia properties in order to accommodate growth of another existing tenant.

Real Estate Operating Expenses

Operating expenses from the Same Property Portfolio increased approximately $9.7 million for the three months ended September 30, 2014 compared to 2013 due primarily to (1) an increase of approximately $7.3 million, or 8.1%, in real estate taxes, which we primarily experienced in our Washington, DC and New York regions, (2) an increase of approximately $2.3 million, or 7.7%, in repairs and maintenance expense, which we primarily experienced in our Boston region and (3) an increase of approximately $0.1 million, or 0.2%, in other operating expenses.

Depreciation and Amortization Expense

Depreciation and amortization expense for our Properties Sold Portfolio decreased by approximately $0.7 million for the three months ended September 30, 2014 compared to 2013 due to the additional depreciation expense incurred for the three months ended September 30, 2013 associated with Mountain View Technology Park and Mountain View Research Park Building Sixteen that were both sold on July 29, 2014 and Broad Run Business Park, which was sold on August 22, 2014, and, as a result, we were not recognizing depreciation expense for the full three months ended September 30, 2014.

Other Operating Income and Expense Items

Residential Net Operating Income

Net operating income for our residential properties increased by approximately $0.3 million for the three months ended September 30, 2014 compared to 2013.

The following reflects our occupancy and rate information for The Lofts at Atlantic Wharf, the Residences on The Avenue and The Avant at Reston Town Center for the three months ended September 30, 2014 and 2013.

Hotel Net Operating Income

Net operating income for the Boston Marriott Cambridge (formerly Cambridge Center Marriott) hotel property increased by approximately $0.3 million for the three months ended September 30, 2014 compared to 2013.

The following reflects our occupancy and rate information for the Boston Marriott Cambridge (formerly Cambridge Center Marriott) hotel for the three months ended September 30, 2014 and 2013.

Development and Management Services

Development and management services income increased approximately $1.0 million for the three months ended September 30, 2014 compared to 2013. Management fee and development fee income each increased approximately $0.5 million. The increase in management fees is due primarily to approximately $0.4 million of

management, leasing and legal fees from properties and leasing transactions in the Boston and Washington, DC regions and approximately $0.1 million related to an increase in service income. The increase in development fees is primarily due to an increase in fees associated with tenant improvement project management in our New York region.

General and Administrative

General and administrative expenses decreased approximately $2.3 million for the three months ended September 30, 2014 compared to 2013 due primarily to the timing of the recognition of expenses under the Transition Benefits Agreement that we entered into with Mortimer B. Zuckerman in 2013. On March 11, 2013, we announced that Owen D. Thomas would succeed Mr. Zuckerman as our Chief Executive Officer, effective April 2, 2013. Mr. Zuckerman will continue to serve as Executive Chairman for a transition period and thereafter is expected to continue to serve as the Non-Executive Chairman of the Board. In connection with succession planning, Mr. Zuckerman entered into the Transition Benefits Agreement with us. Because Mr. Zuckerman remained employed by us through July 1, 2014, he is entitled to receive, on January 1, 2015, a lump sum cash payment of $6.7 million and an equity award with a targeted value of approximately $11.1 million. The cash payment and equity award vested in three equal installments on each of March 10, 2013, October 1, 2013 and July 1, 2014. As a result, we recognized approximately $2.6 million of compensation expense during the three months ended September 30, 2013. In addition, we had a decrease of approximately $1.2 million in the value of our deferred compensation plan. These decreases were partially offset by an increase of approximately $0.5 million related to the net effect of the termination of the 2011 OPP Awards and the issuance of the 2014 MYLTIP Units (See Note 11 to the Consolidated Financial Statements) and an increase of approximately $1.0 million in other general and administrative expenses, which includes compensation expense.

Wages directly related to the development and leasing of rental properties are not included in our operating results. These costs are capitalized and included in real estate assets or deferred charges on our Consolidated Balance Sheets and amortized over the useful lives of the real estate. Capitalized wages for the three months ended September 30, 2014 and 2013 were approximately $3.4 million and $3.1 million, respectively. These costs are not included in the general and administrative expenses discussed above.

Transaction Costs

During the three months ended September 30, 2014, we incurred approximately $1.4 million of transaction costs, which related to (1) approximately $0.4 million for the pending sale of Patriots Park in Reston, Virginia (See Note 13 to the Consolidated Financial Statements), (2) approximately $0.3 million for the formation of the joint venture agreement to sell to a third-party a 45% interest in each of 601 Lexington Avenue in New York City and Atlantic Wharf Office Building and 100 Federal Street in Boston, Massachusetts (See Note 13 to the Consolidated Financial Statements) and (3) approximately $0.7 million related to the pursuit or sale of other assets and the formation of joint venture agreements. During the three months ended September 30, 2013, we incurred approximately $0.8 million of transaction costs of which approximately $0.5 million related to costs for transactions in New York City.

Other Income and Expense Items

Income from Unconsolidated Joint Ventures

For the three months ended September 30, 2014 compared to 2013, income from unconsolidated joint ventures decreased by approximately $10.3 million due primarily to an approximately $11.3 million decrease in our share of net income from the sale of the Eighth Avenue and 46th Street project in New York City on July 19, 2013 partially offset by an approximately $1.0 million increase in our share of net income from our other unconsolidated joint ventures, which was primarily related to termination income we received in connection with our Metropolitan Square property in Washington, DC.

Gains on Consolidation of Joint Ventures

On April 10, 2013, we acquired the Mountain View Research Park and Mountain View Technology Park properties from our Value-Added Fund for an aggregate purchase price of approximately $233.5 million. Prior to the acquisition, our ownership interest in the properties was approximately 39.5%. As a result of the acquisition, we own 100% of the properties and account for them on a consolidated basis. During the three months ended September 30, 2013, we recognized an adjustment to the gain on consolidation totaling approximately $2.1 million.

On May 31, 2013, our two joint venture partners in 767 Venture, LLC (the entity that owns 767 Fifth Avenue in New York City) transferred all of their interests in the joint venture to third parties. In connection with the transfer, we and our new joint venture partners modified our relative decision making authority and consent rights with respect to the joint venture’s assets and operations. These changes resulted in us having sufficient financial and operating control over 767 Venture, LLC such that we now account for the assets, liabilities and operations of 767 Venture, LLC on a consolidated basis in our financial statements instead of under the equity method of accounting. Our ownership interest in 767 Venture, LLC remained unchanged at 60%. During the three months ended September 30, 2013, we recognized a downward adjustment of approximately $3.9 million to the non-cash gain on our investment of approximately $363.4 million, therefore resulting in a non cash gain of approximately $359.5 million. The gain on consolidation resulted from us recognizing the assets, liabilities and equity (including noncontrolling interests) of the joint venture at fair value on the date of consolidation resulting in the recognition of a gain on consolidation equal to the difference between the fair value of our equity interest totaling approximately $721.3 million (as reflected in the business combination table appearing on pages 132 and 133 of the Company’s Form 10-K for the fiscal year ended December 31, 2013) and the carrying value of our previously held equity interest totaling approximately $361.8 million. The fair value was determined based on the purchase price paid by the new joint venture partners through a sales process managed by a major New York City sales brokerage firm.

Interest and Other Income

Interest and other income decreased approximately $0.5 million for the three months ended September 30, 2014 compared to 2013 primarily due to a decrease in the average cash balance and interest rates.

Gains (Losses) from Investments in Securities

Gains (losses) from investments in securities for the three months ended September 30, 2014 and 2013 related to investments that we have made to reduce our market risk relating to a deferred compensation plan that we maintain for our officers. Under this deferred compensation plan, each officer who is eligible to participate is permitted 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. In order to reduce our market risk relating to this plan, 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. This enables us to generally match our liabilities to our officers under the deferred compensation plan 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 three months ended September 30, 2014 and 2013, we recognized gains (losses) of approximately

$(0.3) million and $1.0 million, respectively, on these investments. By comparison, our general and administrative expense increased (decreased) by approximately $(0.3) million and $0.9 million during the three months ended September 30, 2014 and 2013, respectively, as a result of increases (decreases) in our liability under our deferred compensation plan that were associated with the performance of the specific investments selected by our officers participating in the plan.

Interest Expense

Interest expense decreased approximately $8.9 million for the three months ended September 30, 2014 compared to 2013 as detailed below:


Component	Change in interest expense for the three months ended September 30, 2014 compared to September 30, 2013

Interest expense directly related to the development of rental properties is not included in our operating results. These costs are capitalized and included in real estate assets on our Consolidated Balance Sheets and amortized over the useful lives of the real estate. As properties are placed in-service, we cease capitalizing interest and interest is then expensed. Interest capitalized for the three months ended September 30, 2014 and 2013 was approximately $12.2 million and $17.4 million, respectively. These costs are not included in the interest expense referenced above.

Discontinued Operations

On April 10, 2014, the FASB issued ASU No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” (“ASU No. 2014-08”). ASU No. 2014-08 clarifies that 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). ASU No. 2014-08 is

effective prospectively for reporting periods beginning after December 15, 2014. Early adoption is permitted, and we early adopted ASU No. 2014-08 during the first quarter of 2014. Our adoption of ASU No. 2014-08 did not have a material impact on our consolidated financial statements.

Prior to the adoption of ASU No. 2014-08, we had the following properties that were considered discontinued operations for the three months ended September 30, 2013: 10 & 20 Burlington Mall Road, One Preserve Parkway and 1301 New York Avenue. Each of these dispositions is discussed below.

Gains on Sales of Real Estate

Noncontrolling interests in property partnerships

Noncontrolling interests in property partnerships increased by approximately $8.8 million for the three months ended September 30, 2014 compared to 2013 as detailed below.

Noncontrolling interest—Common Units of the Operating Partnership

Noncontrolling interest-common units of the Operating Partnership increased by approximately $6.6 million for the three months ended September 30, 2014 compared to 2013 due to increases in allocable income and the noncontrolling interest’s ownership percentage.

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, including balloon payments on maturing debt;

•

fund capital expenditures, including major renovations, tenant improvements and leasing costs;

•

fund development costs;

•

redeem our Operating Partnership’s Series Four Preferred Units;

•

redeem on December 15, 2014 $550 million aggregate principal amount of our Operating Partnership’s unsecured senior notes that were scheduled to mature in 2015;

•

fund possible property acquisitions; and

•

make the minimum distribution required to maintain our 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;

•

issuances of our equity securities and/or additional preferred or common units of partnership interest in our Operating Partnership;

•

our Operating Partnership’s Unsecured Line of Credit or other short-term bridge facilities;

•

construction loans;

•

long-term secured and unsecured indebtedness (including unsecured exchangeable indebtedness); and

•

sales of real estate or ownership interests in our assets.

We draw on multiple financing sources to fund our long-term capital needs. Our Operating Partnership’s Unsecured Line of Credit is utilized 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 be guaranteed by our Operating Partnership, 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.

Contractual rental revenue, recoveries from tenants, other income from operations, available cash balances and draws on our Operating Partnership’s Unsecured Line of Credit are our principal sources of capital used to pay operating expenses, debt service, recurring capital expenditures and the minimum distribution required to enable us to maintain our 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 necessary funds for our short-term liquidity needs.

Material adverse changes in one or more sources of capital may adversely affect our net cash flows. Such changes, in turn, could adversely affect our ability to fund dividends and distributions, debt service payments 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 our Operating Partnership’s Unsecured Line of Credit and unsecured senior notes.

The completion of our ongoing developments, through 2019, have remaining costs to fund of approximately $1.3 billion. We also have approximately $165 million (of which our share is approximately $45 million) of secured debt that matures in 2015 and our Operating Partnership has elected to redeem on December 15, 2014 the $300 million and $250 million of its unsecured senior notes that were scheduled to mature on April 15, 2015 and June 1, 2015, respectively. We believe that our strong liquidity, including available cash as of November 3, 2014 of approximately $2.6 billion, which includes approximately $1.9 billion of restricted cash which is being held for possible investment in a like-kind exchange in accordance with Section 1031 of the Internal Revenue Code, the approximately $984 million available under our Operating Partnership’s Unsecured Line of Credit and proceeds from potential asset sales provide sufficient capacity to meet our debt obligations and fund our remaining capital requirements on existing development projects, our foreseeable potential development activity and pursue additional attractive investment opportunities. We also have full availability under our $600 million ATM program. Given the relatively low interest rates currently available to us in the debt markets, we may seek to enhance our liquidity in the future, which may result in us carrying additional cash and cash equivalents pending our Operating Partnership’s use of the proceeds. In order to reduce future cash interest payments, as well as future amounts due at maturity or upon redemption, we may, from time to time, purchase unsecured senior notes for cash in open market purchases or privately negotiated transactions, or both. We will evaluate any such potential transactions in light of then-existing market conditions, taking into account the trading prices of the notes, our current liquidity and prospects for future access to capital.

REIT Tax Distribution Considerations

Dividend

As a REIT we are subject to a number of organizational and operational requirements, including a requirement that we currently distribute at least 90% of our annual taxable income. Our policy is to distribute at least 100% of our taxable income to avoid paying federal tax. On December 2, 2013, we announced that our Board of Directors declared a special cash dividend of $2.25 per common share payable on January 29, 2014 to shareholders of record as of the close of business on December 31, 2013. The decision to declare a special dividend was primarily a result of the sale of a 45% interest in our Times Square Tower property in October 2013. The Board of Directors did not make any change in our policy with respect to regular quarterly dividends. Holders of common units of limited partnership interest in Boston Properties Limited Partnership, our Operating Partnership, as of the close of business on December 31, 2013 received the same distribution on January 29, 2014. Our Board of Directors will continue to evaluate our 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 our Board of Directors will not differ materially (See “—Sales” and “—Application of Recent Regulations” below).

Sales

To the extent that we sell assets at a taxable gain and cannot efficiently use the proceeds in a tax deferred manner for either our development activities or attractive acquisitions, we would, at the appropriate time, decide whether it is better to declare a special dividend, adopt a stock repurchase program, reduce our indebtedness or retain the cash for 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 our common stock and REIT distribution requirements. At a minimum, we expect that we would distribute at least that amount of proceeds necessary for us to avoid paying corporate level tax on the applicable gains realized from any asset sales.

Application of Recent Regulations

In September of 2013, the Internal Revenue Service released final regulations governing when taxpayers like us must capitalize and depreciate costs for acquiring, maintaining, repairing and replacing tangible property and when they can deduct such costs. These final regulations are effective for tax years beginning on or after January 1, 2014. These regulations would permit us to deduct certain types of expenditures, like most tenant improvements, that were previously required to be capitalized by us. They also allow us to make a one-time election to immediately deduct certain amounts that were capitalized in previous years that are not required to be capitalized under the new regulations. We continue to analyze the application of the new regulations to our business. Although such an election would have no impact on our GAAP financial statements or Funds from Operations, it could materially reduce our taxable income and therefore our dividend payout requirements under applicable REIT tax regulations for 2014. It could also have an impact on our dividend payout requirements in future years, as the amounts deducted in 2014 will no longer be depreciated over time, and amounts expended and deducted in future periods will vary, potentially resulting in more variation in our distribution requirement from year to year depending on our annual cost of now-deductible tenant improvements and other expenses that previously would have been capitalized. There can be no assurance that we will make such an election and, if we do, the amount that we will deduct or the impact, if any, on the dividends declared by our Board of Directors in 2014 or in future taxable years.

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 were approximately $0.8 billion and $1.6 billion at September 30, 2014 and 2013, respectively, representing a decrease of approximately $0.8 billion. The following table sets forth changes in cash flows:


	Nine months ended September 30,
	2014			2013			Increase (Decrease)
	(in thousands)
Net cash provided by operating activities	$	469,677		$	550,421		$	(80,744	)
Net cash used in investing activities		(488,256	)		(453,445	)		(34,811	)
Net cash provided by (used in) financing activities		(1,499,894	)		502,321			(2,002,215	)

Our principal source of cash flow is related to the operation of our office properties. The average term of our in-place tenant leases, including our unconsolidated joint ventures, is approximately 6.8 years with occupancy rates historically in the range of 91% 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 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, secured and unsecured borrowings and equity offerings.

For the nine months ended September 30, 2014, our total dividends payments exceeded our cash flow from operating activities due to the special dividend which was declared in December 2013 and paid to common stockholders and common unitholders of our Operating Partnership in January 2014. The cash flows distributed were primarily a result of the sale of a 45% interest in our Times Square Tower property in October 2013 and were included as part of cash flows provided by financing activities. Dividends will generally exceed cash flows from operating activities during periods in which we sell significant real estate assets and the distribution of gains occurs in a different period.

Cash is used in investing activities to fund acquisitions, development, net investments in unconsolidated joint ventures and recurring and nonrecurring 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 nine months ended September 30, 2014 and 2013 consisted primarily of funding our development projects and the proceeds from the sales of real estate and for the nine months ended September 30, 2013 the acquisition of Mountain View Research and Technology Parks, 535 Mission Street and Salesforce Tower (formerly Transbay Tower) and Reston, Virginia land parcels, as detailed below:

Net cash used in investing activities	$	(488,256	)	$	(453,445	)

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

•

On February 6, 2013, we completed the acquisition of 535 Mission Street, a development site, in San Francisco, California for an aggregate purchase price of approximately $71.0 million in cash, including work completed and materials purchased to date.

•

On March 26, 2013, the consolidated joint venture in which we have a 95% interest completed the acquisition of a land parcel in San Francisco, California which will support a 61-story, 1.4 million square foot Class A office tower known as Salesforce Tower (formerly Transbay Tower). The purchase price for the land was approximately $192.0 million.

•

Cash used in financing activities for the nine months ended September 30, 2014 totaled approximately $1.5 billion. This consisted primarily of the repayment at maturity of $747.5 million of 3.625% exchangeable senior notes due 2014, the payments of regular and special dividends and distributions to our shareholders and unitholders and repayment of secured mortgage debt. Future debt payments are discussed below under the heading “Capitalization-Debt Financing.”

Capitalization

At September 30, 2014, our total consolidated debt was approximately $10.5 billion. The GAAP weighted-average annual interest rate on our consolidated indebtedness was 4.46% (with a coupon/stated rate of 5.00%) and the weighted-average maturity was approximately 5.0 years.

Consolidated debt to total consolidated market capitalization ratio, defined as total consolidated debt as a percentage of the value of our outstanding equity securities plus our total consolidated debt, is a measure of leverage commonly used by analysts in the REIT sector. Our total consolidated market capitalization was approximately $30.5 billion at September 30, 2014. Our total consolidated market capitalization was calculated using the September 30, 2014 closing stock price of $115.76 per common share and the following: (1) 153,099,786 shares of our common stock, (2) 16,456,297 outstanding common units of partnership interest in our Operating Partnership (excluding common units held by us), (3) an aggregate of 1,505,386 common units issuable upon conversion of all outstanding LTIP Units, assuming all conditions have been met for the conversion of the LTIP Units, (4) 40,440 Series Four Preferred Units of partnership interest in our Operating Partnership multiplied by the fixed liquidation preference of $50 per unit, (5) 80,000 shares (8,000,000 depositary shares, each representing 1/100th of a share), of our 5.25% Series B Cumulative Redeemable Preferred Stock, at a price of $2,500 per share ($25 per depositary share) and (6) our consolidated debt totaling approximately $10.5 billion. At September 30, 2014, our total consolidated debt, which excludes debt collateralized by our unconsolidated joint ventures represented approximately 34.37% of our total consolidated market capitalization.

Following the consolidation of 767 Venture, LLC (the entity that owns 767 Fifth Avenue (the General Motors Building)), effective June 1, 2013, our consolidated debt increased significantly compared to prior periods even though our economic interest in 767 Venture, LLC remained substantially unchanged. As a result, we believe the presentation of total adjusted debt may provide investors with a more complete picture of our share of consolidated and unconsolidated debt. Total adjusted debt is defined as our total consolidated debt, plus our share of unconsolidated joint venture debt, minus our joint venture partners’ share of consolidated debt, and was approximately $9.9 billion at September 30, 2014. In addition, in light of the difference between our total consolidated debt and our total adjusted debt, we believe that also presenting our total adjusted debt to total adjusted market capitalization ratio may provide investors with a more complete picture of our leverage in relation to the overall size of our company. The calculation of the total adjusted debt to total adjusted market capitalization ratio is the same as consolidated debt to total consolidated market capitalization ratio except that the total adjusted debt balance is used in lieu of the total consolidated debt balance. At September 30, 2014 our total adjusted debt represented approximately 33.20% of our total adjusted market capitalization.

The calculation of total consolidated and adjusted market capitalization does not include 394,590 2012 OPP Units, 314,974 2013 MYLTIP Units and 483,555 2014 MYLTIP Units because, unlike other LTIP Units, they are not earned until certain return thresholds are achieved. These percentages will fluctuate with changes in the market value of our common stock and does 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 ours, whose assets are primarily income-producing real estate, the consolidated debt to total consolidated market capitalization ratio and the adjusted debt to total adjusted market capitalization ratio may provide investors with an alternate indication of leverage, so long as it is evaluated along with other financial ratios and 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 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Debt Financing

As of September 30, 2014, we had approximately $10.5 billion of outstanding consolidated indebtedness, representing approximately 34.37% of our total consolidated market capitalization as calculated above consisting of approximately (1) $5.837 billion (net of discount) in publicly traded unsecured senior notes having a weighted-average interest rate of 4.44% per annum and maturities in 2015, 2018, 2019, 2020, 2021, 2023 and 2024; (2) $4.3 billion of property-specific mortgage debt having a GAAP weighted-average interest rate of 4.30% per annum and weighted-average term of 3.5 years and (3) $0.3 billion of mezzanine notes payable, associated with 767 Fifth Avenue (the General Motors Building), having a GAAP interest rate of 5.53% per annum and maturing in 2017.

Unsecured Line of Credit

On July 26, 2013, our Operating Partnership amended and restated the revolving credit agreement governing its Unsecured Line of Credit, which, among other things, (1) increased the total commitment from $750.0 million to $1.0 billion, (2) extended the maturity date from June 24, 2014 to July 26, 2018 and (3) reduced the per annum variable interest rates and other fees. Our Operating Partnership may increase the total commitment to $1.5 billion, subject to syndication of the increase and other conditions. At our Operating Partnership’s option, loans outstanding under the Unsecured Line of Credit will bear interest at a rate per annum equal to (1) in the case of loans denominated in Dollars, Euro or Sterling, LIBOR or, in the case of loans denominated in Canadian Dollars, CDOR, in each case, plus a margin ranging from 0.925% to 1.70% based on our Operating Partnership’s credit rating or (2) an alternate base rate equal to the greatest of (a) the Administrative Agent’s prime rate, (b) the Federal Funds rate plus 0.5% or (c) LIBOR for a one month period plus 1.00%, in each case, plus a margin

ranging from 0.0% to 0.70% based on our Operating Partnership’s credit rating. The Unsecured Line of Credit also contains a competitive bid option that allows banks that are part of the lender consortium to bid to make loan advances to our Operating Partnership at a reduced interest rate. In addition, our Operating Partnership is obligated to pay (1) in quarterly installments a facility fee on the total commitment at a rate per annum ranging from 0.125% to 0.35% based on our Operating Partnership’s credit rating and (2) an annual fee on the undrawn amount of each letter of credit equal to the LIBOR margin. Based on our Operating Partnership’s current credit rating, the LIBOR and CDOR margin is 1.00%, the alternate base rate margin is 0.0% and the facility fee is 0.15%. Our ability to borrow under our Operating Partnership’s Unsecured Line of Credit is subject to our compliance with a number of customary financial and other covenants on an ongoing basis, including:

•

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 year;

•

a secured debt leverage ratio not to exceed 55%;

•

a fixed charge coverage ratio of at least 1.40;

•

an unsecured 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 year;

•

an unsecured debt interest coverage ratio of at least 1.75; and

•

limitations on permitted investments.

We believe we are in compliance with the financial and other covenants listed above.

As of September 30, 2014, we had no borrowings and outstanding letters of credit totaling approximately $15.8 million outstanding under the Unsecured Line of Credit, with the ability to borrow approximately $984.2 million. As of November 3, 2014, we had no borrowings and outstanding letters of credit totaling approximately $16.4 million outstanding under the Unsecured Line of Credit, with the ability to borrow approximately $983.6 million.

On November 3, 2014, our Operating Partnership issued a notice to redeem on December 15, 2014 $300.0 million in aggregate principal amount of its 5.625% senior notes due 2015, which were scheduled to mature on April 15, 2015. The redemption price will equal the sum of (a) the present values as of the redemption date of the remaining scheduled payments of principal and interest from the redemption date to maturity (excluding any accrued and unpaid interest) discounted on a semi-annual basis at a rate equal to the yield to maturity of a comparable United States Treasury security plus 0.35%, plus (b) accrued interest to, but excluding, December 15, 2014, as provided in the applicable indenture. The redemption price will be calculated three business days prior to the redemption date and will be payable on December 15, 2014 in accordance with the terms of the indenture.

(4)

On November 3, 2014, our Operating Partnership issued a notice to redeem on December 15, 2014 $250.0 million in aggregate principal amount of its 5.000% senior notes due 2015, which were scheduled to mature on June 1, 2015. The redemption price will equal the sum of (a) the present values as of the redemption date of the remaining scheduled payments of principal and interest from the redemption date to maturity (excluding any accrued and unpaid interest) discounted on a semi-annual basis at a rate equal to the yield to maturity of a comparable United States Treasury security plus 0.25%, plus (b) accrued interest to, but excluding, December 15, 2014, as provided in the applicable indenture. The redemption price will be calculated three business days prior to the redemption date and will be payable on December 15, 2014 in accordance with the terms of the indenture.

Our unsecured senior notes are redeemable at our option, in whole or in part, at a redemption price equal to the greater of (i) 100% of their principal amount or (ii) the sum of the present value of the remaining scheduled payments of principal and interest discounted at a rate equal to the yield on U.S. Treasury securities with a comparable maturity plus 35 basis points (or 20 basis points in the case of the $500 million of notes that mature on September 1, 2023, 25 basis points in the case of the $250 million and $700 million of notes that mature on June 1, 2015 and February 1, 2024, respectively, 40 basis points in the case of the $700 million of notes that mature on October 15, 2019 and 30 basis points in the case of the $700 million and $850 million of notes that mature on November 15, 2020 and May 15, 2021, respectively), in each case plus accrued and unpaid interest to the redemption date. The indenture under which our unsecured senior notes were issued contains restrictions on incurring debt and using our assets as security in other financing transactions and other customary financial and other covenants, 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) unencumbered asset value to be no less than 150% of our unsecured debt. As of September 30, 2014, we believe we were in compliance with each of these financial restrictions and requirements.

(1)

GAAP interest rate differs from the stated interest rate due to the inclusion of the amortization of financing charges, effects of hedging transactions and adjustments required to reflect loans at their fair values upon acquisition or consolidation. All adjustments to reflect loans at their fair value upon acquisition or consolidation are noted above.

(2)	This property is owned by a consolidated joint venture in which we have a 60% interest.

(3)

In connection with the assumption of the loan, we guaranteed the joint venture’s obligation to fund various escrows, including tenant improvements, taxes and insurance in lieu of cash deposits. As of September 30, 2014, the maximum funding obligation under the guarantee was approximately $14.8 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.

(4)	The mortgage loan requires interest only payments with a balloon payment due at maturity.

(5)

On December 19, 2006, we terminated the forward-starting interest rate swap contracts related to this financing and received approximately $10.9 million, which amount is reducing our GAAP interest expense for this mortgage over the term of the financing, resulting in an effective interest rate of 5.41% per annum for the financing. The stated interest rate is 5.57% per annum.

(6)	On October 30, 2014, this property was owned by a consolidated joint venture in which we have a 55% interest.

(7)	In connection with the mortgage financing we have agreed to guarantee approximately $28.8 million related to our obligation to provide funds for certain tenant re-leasing costs.

(8)

Under our interest rate hedging program, we are reclassifying into earnings over the eight-year term of the loan as an increase in interest expense approximately $26.4 million (approximately $3.3 million per year) of the amounts recorded on our Consolidated Balance Sheets within Accumulated Other Comprehensive Loss resulting in an effective interest rate of 7.02% per annum.

(9)	This property is owned by a consolidated joint venture in which we have a 50% interest.

Mezzanine Notes Payable

The following represents the outstanding principal balances due under the mezzanine notes payable at September 30, 2014:

(1)	GAAP interest rate differs from the stated interest rate due to adjustments required to reflect loans at their fair values upon acquisition or consolidation. The adjustment to reflect the loan at its fair value upon consolidation is noted above.

(2)	This property is owned by a consolidated joint venture in which we have a 60% interest.

(3)	The mortgage loan requires interest only payments with a balloon payment due at maturity.

Outside Members’ Notes Payable

In conjunction with the consolidation of 767 Fifth Avenue (the General Motors Building), we recorded loans payable to the joint venture’s partners totaling $450.0 million and related accrued interest payable totaling approximately $175.8 million. The partner loans bear interest at a fixed rate of 11.0% per annum and mature on June 9, 2017. We have eliminated in consolidation our partner loan totaling $270.0 million and our share of the related accrued interest payable of approximately $122.1 million at September 30, 2014. The remaining notes payable to the outside joint venture partners and related accrued interest payable totaling $180.0 million and approximately $81.4 million as of September 30, 2014 have been reflected as Outside Members’ Notes Payable and within Accrued Interest Payable, respectively, on our Consolidated Balance Sheets. The related interest expense from the Outside Members’ Notes Payable totaling approximately $7.1 million and $21.0 million for the three and nine months ended September 30, 2014 is fully allocated to the outside joint venture partners as an adjustment to Noncontrolling Interests in Property Partnerships in our Consolidated Statements of Operations.

Off-Balance Sheet Arrangements—Joint Venture Indebtedness

We have investments in unconsolidated joint ventures with our effective ownership interests ranging from 25% to 60%. Six of these ventures have mortgage indebtedness. We exercise significant influence over, but do not control, these entities and therefore they are presently accounted for using the equity method of accounting. See also Note 4 to the Consolidated Financial Statements. At September 30, 2014, the aggregate carrying amount of debt, including both our and our partners’ share, incurred by these ventures was approximately $753.7 million (of which our proportionate share is approximately $331.8 million). The table below summarizes the outstanding debt of these joint venture properties at September 30, 2014. 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) on certain of the loans.

State and Local Tax Matters

Because we are organized and qualify as a REIT, we are generally not subject to federal income taxes, but 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 or other inquiries. 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.

Insurance

We carry insurance coverage on our properties of types and in amounts and with deductibles that we believe are in line with coverage customarily obtained by owners of similar properties. In response to the uncertainty in the insurance market following the terrorist attacks of September 11, 2001, the Federal Terrorism Risk Insurance Act (as amended, “TRIA”) was enacted in November 2002 to require regulated insurers to make available coverage for “certified” acts of terrorism (as defined by the statute). The expiration date of TRIA was extended to December 31, 2014 by the Terrorism Risk Insurance Program Reauthorization Act of 2007 (“TRIPRA”) and we can provide no assurance that it will be extended further. Currently, the per occurrence limits of our portfolio property insurance program are $1.0 billion, 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 Terrorism 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. Through June 9, 2014, $1.375 billion of the Terrorism Coverage for 767 Fifth Avenue in excess of $250 million was provided by NYXP, LLC (“NYXP”), as a direct insurer. After June 9, 2014, all of the Terrorism Coverage for 767 Fifth Avenue has been provided by third party insurers. We also currently carry nuclear, biological, chemical and radiological terrorism insurance coverage for acts of terrorism certified under 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 billion. Under TRIA, after the payment of the required deductible and coinsurance, the NBCR Coverage provided by IXP and the Terrorism Coverage provided by NYXP are backstopped by the Federal Government if the aggregate industry insured losses resulting from a certified act of terrorism exceed a “program trigger.” The program trigger is $100 million and the coinsurance is 15%. Under TRIPRA, 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 TRIPRA. We may elect to terminate the NBCR Coverage if the Federal Government seeks recoupment for losses paid under TRIA, if there is a change in our portfolio or for any other reason. In the event TRIPRA is not extended beyond December 31, 2014, (i) our $1.0 billion portfolio property insurance program and the $250 million of additional Terrorism

Coverage for 601 Lexington Avenue will continue to provide Terrorism Coverage through the expiration of the program on March 1, 2015, (ii) the $1.625 billion property insurance program for 767 Fifth Avenue will continue to provide Terrorism Coverage through the expiration of the program on June 9, 2015, (iii) we will evaluate alternative approaches to secure coverage for acts of terrorism thereby potentially increasing our overall cost of insurance, (iv) if such insurance is not available at commercially reasonable rates with limits equal to our current coverage or at all, we may not continue to have full occurrence limit coverage for acts of terrorism, (v) we may not satisfy the insurance requirements under existing or future debt financings secured by individual properties, (vi) we may not be able to obtain future debt financings secured by individual properties and (vii) we may cancel the insurance policies issued by IXP for the NBCR Coverage. We intend to continue to monitor the scope, nature and cost of available terrorism insurance and maintain terrorism insurance in amounts and on terms that are commercially reasonable.

We also currently carry earthquake insurance on our properties located in areas known to be subject to earthquakes in an amount and subject to self-insurance that we believe is commercially reasonable. In addition, this insurance is subject to a deductible in the amount of 5% of the value of the affected property. Specifically, we currently carry earthquake insurance which covers our San Francisco region (excluding Salesforce Tower (formerly Transbay Tower) and through October 22, 2014 excluding 535 Mission Street) with a $120 million per occurrence limit and a $120 million annual aggregate limit, $20 million of which is provided by IXP, as a direct insurer. The builders risk policy maintained for the development of 535 Mission Street in San Francisco included a $15 million per occurrence and annual aggregate limit of earthquake coverage through October 22, 2014 after which time 535 Mission Street was included in our portfolio earthquake insurance program. In addition, the builders risk policy maintained for the development of Salesforce Tower in San Francisco includes a $60 million per occurrence and annual aggregate limit of earthquake coverage (increased from $15 million on July 29, 2014). 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 properties and our NBCR Coverage. NYXP, a captive insurance company which is a wholly-owned subsidiary, acted as a direct insurer with respect to a portion of our Terrorism Coverage for 767 Fifth Avenue through June 9, 2014. NYXP only insured losses which exceeded the program trigger under TRIA and NYXP reinsured with a third-party insurance company any coinsurance payable under TRIA. Insofar as we own IXP and NYXP, we are responsible for their liquidity and capital resources, and the accounts of IXP and NYXP 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 and NYXP would also be responsible for any recoupment charges by the Federal Government in the event losses are paid out and their insurance policies are maintained after the payout by the Federal Government. If we experience a loss and IXP or NYXP are required to pay under their insurance policies, we would ultimately record the loss to the extent of the required payment. Therefore, insurance coverage provided by IXP and NYXP should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance. In addition, our Operating Partnership has issued a guarantee to cover liabilities of IXP in the amount of $20.0 million.

The mortgages on our properties typically contain requirements concerning the financial ratings of the insurers who provide policies covering the property. We provide the lenders on a regular basis with the identity of the insurance companies in our insurance programs. The ratings of some of our insurers are below the rating requirements in some of our loan agreements and the lenders for these loans could attempt to claim an event of default has occurred under the loan. We believe we could obtain insurance with insurers which satisfy the rating requirements. Additionally, in the future our ability to obtain debt financing secured by individual properties, or the terms of such financing, may be adversely affected if lenders generally insist on ratings for insurers or

amounts of insurance which are difficult to obtain or which result in a commercially unreasonable premium. There can be no assurance that a deficiency in the financial ratings of one or more of our insurers will not have a material adverse effect on us.

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.

Funds from Operations

Pursuant to the revised definition of Funds from Operations adopted by the Board of Governors of NAREIT, we calculate Funds from Operations, or “FFO,” by adjusting net income (loss) attributable to Boston Properties, Inc. common shareholders (computed in accordance with GAAP, including non-recurring items) for gains (or losses) from sales of properties, impairment losses on depreciable real estate of consolidated real estate, impairment losses on investments in unconsolidated joint ventures driven by a measurable decrease in the fair value of depreciable real estate held by the unconsolidated joint ventures, real estate related depreciation and amortization, and after adjustment for unconsolidated partnerships, joint ventures and preferred distributions. FFO is a non-GAAP financial measure. The use of FFO, combined with the required primary GAAP presentations, has been fundamentally beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. Management generally considers FFO to be a useful measure for reviewing our comparative operating and financial performance because, by excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment losses on depreciable real estate of consolidated real estate, impairment losses on 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 excluding real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO can help one compare the operating performance of a company’s real estate between periods or as compared to different 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.

FFO should not be considered as an alternative to net income attributable to Boston Properties, Inc. common shareholders(determined in accordance with GAAP) as an indication of our performance. FFO does not represent cash generated from operating activities determined in accordance with GAAP and is not a measure of liquidity or an indicator of our ability to make cash distributions. We believe that to further understand our performance, FFO should be compared with our reported net income attributable to Boston Properties, Inc. and considered in addition to cash flows in accordance with GAAP, as presented in our Consolidated Financial Statements.

The following table presents a reconciliation of net income attributable to Boston Properties, Inc. common shareholders to FFO for the three months ended September 30, 2014 and 2013:

Contractual Obligations

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 the third quarter of 2014, we paid approximately $45.4 million to fund tenant-related obligations, including tenant improvements and leasing commissions, and incurred approximately $152.3 million of new tenant-related obligations associated with approximately 1.8 million square feet of second generation leases, or approximately $83 per square foot. In addition, we signed leases for approximately 50,000 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 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.” In the aggregate, during the third quarter of 2014, we signed leases for approximately 1.9 million square feet of space and incurred aggregate tenant-related obligations of approximately $157.4 million, or approximately $83 per square foot.

ITEM 3—Quantitative and Qualitative Disclosures about Market Risk.

As of September 30, 2014, approximately $10.5 billion of our consolidated borrowings bore interest at fixed rates and none of our consolidated borrowings bore interest at variable rates. The fair value of these instruments is affected by changes in market interest rates. The table below does not include our unconsolidated joint venture debt. For a discussion concerning our unconsolidated joint venture debt, See Note 4 to the Consolidated Financial Statements and “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capitalization—Off-Balance Sheet Arrangements—Joint Venture Indebtedness.”

At September 30, 2014, the weighted-average coupon/stated rates on our fixed rate debt was 5.00% per annum. The weighted-average coupon/stated rates for our unsecured debt was 4.44% per annum.

At September 30, 2014, we had no outstanding variable rate debt.

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.

ITEM 4—Controls

and Procedures.

(a) Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this report, our management, with the participation of our Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that these disclosure controls and procedures were effective as of the end of the period covered by this report.

(b) Changes in Internal Control Over Financial Reporting. No change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) occurred during the third quarter of our fiscal year ending December 31, 2014 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1—Legal Proceedings.

We are subject to 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 our financial position, results of operations or liquidity.
