PART I

ITEM 1. BUSINESS

Overview

Empire State Realty OP, L.P. is the entity through which Empire State Realty Trust, Inc. ("ESRT"), a self-administered and self-managed real estate investment trust, or REIT, conducts all of its business and owns (either directly or through subsidiaries) substantially all of its assets. We own, manage, operate, acquire and reposition office and retail properties in Manhattan and the greater New York metropolitan area, including the Empire State Building, the world's most famous building. Empire State Realty Trust, Inc.'s Class A common stock, par value $0.01 per share, is listed on the New York Stock Exchange under the symbol "ESRT."

As of December 31, 2015, our total portfolio, containing 10.1 million rentable square feet of office and retail space, was 87.3% occupied. Including signed leases not yet commenced, our total portfolio was 89.1% leased. As of December 31, 2015, we owned 14 office properties (including three long-term ground leasehold interests) encompassing approximately 9.3 million rentable square feet of office space, which were approximately 86.7% occupied or 88.6% leased including signed leases not yet commenced. Nine of these properties are located in the midtown Manhattan market and encompass approximately 7.5 million rentable square feet of office space, including the Empire State Building. Our Manhattan office properties also contain 518,792 rentable square feet of premier retail space on their ground floor and/or contiguous levels. Our remaining five office properties are located in Fairfield County, Connecticut and Westchester County, New York, encompassing approximately 1.9 million rentable square feet. The majority of square footage for these five properties is located in densely populated metropolitan communities with immediate access to mass transportation. Additionally, we have entitled land at the Stamford Transportation Center in Stamford, Connecticut, adjacent to one of our office properties, that will support the development of an approximately 380,000 rentable square foot office building and garage, which we refer to herein as Metro Tower. As of December 31, 2015, our portfolio also included four standalone retail properties located in Manhattan and two standalone retail properties located in the city center of Westport, Connecticut, encompassing 204,452 rentable square feet in the aggregate. As of December 31, 2015, our standalone retail properties were 100.0% leased in the aggregate.

The Empire State Building offers panoramic views of New York and neighboring states from its world-famous 86th and 102nd floor observatories that draw millions of visitors per year. The number of visitors to the observatories was approximately 4.1 million and 4.3 million for the years ended December 31, 2015 and 2014, respectively. The 86th floor observatory has a 360-degree outdoor deck as well as indoor viewing galleries to accommodate guests day and night, all year-round. The 102nd floor observatory is entirely indoors and offers a 360-degree view of New York City from 1,250 feet above ground.

We were organized as a Delaware limited partnership on November 28, 2011. We did not have any assets other than cash and did not have any meaningful operating activity until the consummation of the Offering and the related acquisition of our predecessor and certain non-controlled entities controlled by our predecessor on October 7, 2013 as part of the formation transactions. Our operations commenced upon completion of the Offering and related formation transactions on October 7, 2013. ESRT, as the sole general partner in our company, has responsibility and discretion in the management and control in our company, and our limited partners, in such capacity, have no authority to transact business for, or participate in the management activities, of our company. As of December 31, 2015, ESRT owned approximately 44.9% of our operating partnership units.

Our Competitive Strengths

We believe that we distinguish ourselves from other owners and operators of office and retail properties as a result of the following competitive strengths:

•

Irreplaceable Portfolio of Office Properties in Midtown Manhattan. Our Manhattan office properties are located in one of the most prized office markets in the world due to a combination of supply constraints, high barriers to entry, near-term and long-term prospects for job creation, vacancy absorption and rental rate growth. Management believes these properties could not be replaced today on a cost-competitive basis, if at all. As of December 31, 2015, we owned nine Manhattan office properties (including three long-term ground leasehold interests) encompassing approximately 7.5 million rentable square feet of office space, including the Empire State Building, our flagship property. Unlike traditional office buildings, the Empire State Building provides us with a significant source of income from its observatory and broadcasting operations. All of these properties include premier retail space on their ground floor and/or contiguous levels, which comprise 518,792 rentable square feet in the aggregate and some of which have recently undergone significant redevelopments. We believe the high quality of our buildings, services and

amenities, their desirable locations and commuter access to mass transportation should allow us to increase rents and occupancy to generate positive cash flow and growth.

•

Expertise in Repositioning and Redeveloping Manhattan Office Properties. We have substantial expertise in redeveloping and repositioning Manhattan office properties, having invested a total of approximately $645.0 million (excluding tenant improvement costs and leasing commissions) in our Manhattan office properties since we assumed full control of the day-to-day management of these properties beginning with One Grand Central Place in November 2002 through 2006. The $645.0 million includes amounts invested at 1400 Broadway and 111 West 33rd Street (formerly known as 112 West 34th Street), which were acquired after the completion of the Offering. We have substantial experience in upgrading, redeveloping and modernizing (or are in the process thereof) building lobbies, corridors, bathrooms and elevator cabs and old, antiquated spaces to include new ceilings, lighting, pantries and base building systems (including electric distribution and air conditioning), as well as enhanced tenant amenities. To complete our portfolio-wide redevelopment program as presently defined, we intend to spend an additional $30.0 million to $50.0 million on repositioning activities at our existing Manhattan office properties (excluding tenant improvement costs and leasing commissions), most of which remains at the Empire State Building. We have successfully aggregated and are continuing to aggregate smaller spaces to offer larger blocks of space, including multiple floors, that are attractive to larger, higher credit-quality tenants and to offer new, pre-built suites with improved layouts. As part of this program, we have converted some or all of the second floor office space of certain of our Manhattan office properties to higher rent retail space. We believe that the post-redevelopment high quality of our buildings and the service we provide also attract higher credit-quality tenants for larger spaces at rents above similar vintage buildings, and below new construction, thus defining a new price point and allowing us to drive superior returns on invested capital per square foot. In addition, we believe that, based on the results of our base building energy efficiency retrofit, and energy efficient tenant build-outs, at the Empire State Building, the lessons of which we are applying throughout our portfolio, we derive cost savings through innovative energy efficiency retrofitting and sustainability initiatives, reducing direct and indirect energy costs paid both by tenants and by us throughout our other Manhattan office properties and greater New York metropolitan area office properties, and that this improves our competitive position.

•

Leader in Energy Efficiency Retrofitting. We have pioneered certain practices in energy efficiency, and at the Empire State Building we have partnered with the Clinton Climate Initiative, Johnson Controls Inc., Jones Lang LaSalle and the Rocky Mountain Institute to create and implement a groundbreaking, replicable process for integrating energy efficiency retrofits in the existing built environment. The reduced energy consumption reduces costs for us and our tenants, and we believe creates a competitive advantage for our properties. We believe that higher quality tenants in general place a higher priority on sustainability, controlling costs, and minimizing contributions to greenhouse gases. We believe our expertise in this area gives us the opportunity to attract higher quality tenants at higher rental rates and to reduce our expenses. As a result of our efforts, approximately 64.3% of our portfolio square feet is Energy Star certified, including the Empire State Building. As a result of the energy efficiency retrofits, we estimate that the Empire State Building will save at least 38% of its pre-retrofit level of energy use, resulting in at least $4.4 million of annual energy cost savings. Johnson Controls Inc. has guaranteed minimum energy cost savings of $2.2 million annually, from 2010 through 2025, with respect to certain of the retrofits in which Johnson Controls Inc. was project leader. Actual 2013 energy cost savings was $2.8 million. We are implementing cost justified energy efficiency retrofit projects in our Manhattan and greater New York metropolitan area office properties based on our work at the Empire State Building. Finally, we maintain a series of management practices utilizing recycling of tenant and construction waste, recycled content carpets, low off-gassing paints and adhesives, “green” pest control and cleaning solutions, and recycled paper products throughout our office portfolio. We believe that our portfolio’s attractiveness is enhanced by these practices and that this should result in higher rental rates, longer lease terms and higher quality tenants.

•

Attractive Retail Locations in Densely Populated Metropolitan Communities. As of December 31, 2015, our portfolio also included six standalone retail properties and retail space at the ground floor and/or lower levels of our Manhattan office properties, encompassing 723,244 rentable square feet in the aggregate, which were approximately 94.3% occupied in the aggregate. All of these properties are located in dynamic retail corridors with convenient access to mass transportation, a diverse tenant base and high pedestrian traffic and/or main destination locations. Our retail portfolio includes 701,811 rentable square feet located in Manhattan and 21,433 rentable square feet located in Westport, Connecticut. Our current retail rents are meaningfully below current market rents, and as we recapture and redevelop retail space, we are able to drive strong positive spreads on newly leased space. We have significant retail expirations in the coming years that will allow us to further increase our cash flows as we continue our redevelopment program. Our retail tenants cover a number of industries, including financial services, and include Allen Edmonds; Ann Taylor; AT&T; Bank of America; Bank Santander (Sovereign Bank); Best Buy Mobile; Charles Schwab; Chipotle; Duane Reade (a division of Walgreen Co.); Ethan Allen; FedEx/Kinko’s; Food Emporium; FootLocker;

Gamestop; HSBC; JP Morgan Chase; Loews Theatre; Lululemon; Men’s Wearhouse; Nike; Panera Bread; Potbelly Sandwich Works; Sprint; Starbucks; Theory; TJ Maxx; Urban Outfitters; and Walgreens. Our Westport, Connecticut retail properties are located on Main Street, the main pedestrian thoroughfare in Westport, Connecticut, and have the advantage of being adjacent to one of the few available large-scale parking lots in town.

•

Experienced and Committed Management Team with Proven Track Record. Our senior management team is highly regarded in the real estate community and has extensive relationships with a broad range of brokers, owners, tenants and lenders. We have developed relationships we believe enable us to both secure high credit-quality tenants on attractive terms, as well as provide us with potential acquisition opportunities. We have substantial in-house expertise and resources in asset and property management, leasing, marketing, acquisitions, construction, development and financing and a platform that is highly scalable. Members of our senior management team have worked in the real estate industry for an average of approximately 32 years with extensive experience in Greater New York area real estate, through many economic cycles. We take an intensive, hands-on approach to the management of our portfolio and quality brand building. As of December 31, 2015, our named executive officers owned 13.1% of ESRT's common stock on a fully diluted basis (including shares of common stock as to which Anthony E. Malkin has the right to vote, but does not have a primary interest), and therefore their interests are aligned with those of ESRT's securityholders and they are incentivized to maximize returns to ESRT's securityholders.

•

Strong Balance Sheet Supportive of Future Growth. As of December 31, 2015, we had total debt outstanding of approximately $1.6 billion, with a weighted average interest rate of 4.12% and a weighted average maturity of 5.4 years. Additionally, we had approximately $760.0 million of available borrowing capacity under our secured revolving and term credit facility as of December 31, 2015. Our debt represented 25.3% of enterprise value and our net debt to EBITDA was 4.9x. Excluding principal amortization, we have no debt maturing in 2016 and approximately $355.8 million of debt maturing in 2017. We continue to extend and ladder our debt maturities, increase our access to a variety of capital sources and maintain low leverage with significant capacity on our balance sheet. This low level of leverage gives us flexibility to cover our capital program and to take advantage of opportunities to acquire additional properties as and when we see compelling opportunities. We believe that lower levered companies outperform over the long term.

Business and Growth Strategies

Our primary business objectives are to maximize cash flow and total returns to our securityholders and to increase the value of our properties through the pursuit of the following business and growth strategies:

•

Vacating, Redeveloping, and Leasing of Redeveloped Space at Our Manhattan Office Properties. As of December 31, 2015, our Manhattan office properties (excluding the retail component of these properties) were approximately 84.9% occupied, or 87.2% leased including signed leases not commenced, and had approximately 1.0 million rentable square feet of available space (excluding signed leases not commenced). Our program of redevelopment necessarily includes vacating older less desirable suites; demolishing them for re-leasing as full or multi-floor blocks, or as new pre-built suites; and re-leasing them. We believe our redevelopment and repositioning program for our Manhattan office properties results in our leasing space to better credit tenants and higher rents, while achieving returns of nine to 22 percent. Over time, as we have created and redeveloped large blocks of available space, we have leased them to higher quality tenants at higher rents, and intend to continue to execute on this program over the years to come. To date we believe these efforts have accelerated our ability to lease space to new higher credit-quality tenants, many of which have expanded the office space they lease from us over time. We also employ a pre-built suite strategy in selected portions of some of our properties to appeal to many credit-worthy smaller tenants by fitting out some available space with new ceilings, lighting, pantries and base building systems (including electric distribution and air conditioning) for immediate occupancy. These pre-built suites deploy energy efficiency strategies developed in our work at the Empire State Building and are designed with efficient layouts sought by a wide array of users which we believe will require only minor painting and carpeting for future re-leasing thus reducing our future costs. We expect to achieve returns on investment of nine to 18 percent on our pre-built suites. Over time, as we have redeveloped the spaces in our buildings, we believe we will increase our occupancy.

•

Increase Existing Below-Market Rents. The purpose of our redevelopment is to sign leases for larger amounts of space to better credit tenants at higher rents. To date, we have capitalized on this opportunity and we believe we have significant embedded, de-risked growth that we can capture as we execute on the successful repositioning of our Manhattan office portfolio and improving market fundamentals to increase rents. For example, we expect to benefit from the re-leasing of 7.5%, or approximately 558,939 rentable square feet (including month-to-month leases), of our Manhattan office leases expiring through December 31, 2016, which we generally believe are currently at below

market rates. These expiring leases represent a weighted average base rent of $44.90 per square foot based on current measurements. As older leases expire, we expect to continue to upgrade certain space to further increase rents. Our concentration in Manhattan and the greater New York metropolitan area should also enable us to benefit from increased rents associated with current and anticipated near-term improvements in the financial and economic environment in these areas. We also expect to benefit from our price positioning, as we command prices that are above comparable vintage properties due to the quality of our newly developed space and our attractive amenities but below new construction.

•

Complete the Redevelopment and Repositioning of Our Current Portfolio. We intend to continue to increase occupancy, improve tenant quality and enhance cash flow and value by completing the redevelopment and repositioning of our Manhattan office properties. We intend selectively to continue to allow leases for smaller spaces to expire or relocate smaller tenants in order to aggregate, demolish and re-demise existing office space into larger blocks of vacant space, which we believe will attract higher credit-quality tenants at higher rental rates. We apply rigorous underwriting analysis to determine if aggregation of vacant space for future leasing to larger tenants will improve our cash flows over the long term. In addition, we are a leader in developing economically justified energy efficiency retrofitting and sustainability and have made it a portfolio-wide initiative. We believe this makes our properties desirable to high credit-quality tenants at higher rental rates and longer lease terms.

•

Pursue Attractive Acquisition and Development Opportunities. We will opportunistically pursue attractive opportunities to acquire office and retail properties. For the foreseeable future, we intend to focus our acquisition strategy primarily on Manhattan office properties and, to a lesser extent, office and multi-tenanted retail properties in densely populated communities in the greater New York metropolitan area and other markets we may identify in the future. We believe we can utilize our industry relationships (including well-known real estate owners in Manhattan), brand recognition, and our expertise in redeveloping and repositioning office properties to identify acquisition opportunities where we believe we can increase occupancy and rental rates. We also believe there is significant growth opportunity to acquire and reposition additional stand-alone retail spaces. Our strong balance sheet, access to capital, and ability to offer operating partnership units in tax deferred acquisition transactions should give us significant flexibility in structuring and consummating acquisitions. Further, we have a development site, Metro Tower at the Stamford Transportation Center, which is adjacent to our Metro Center property, which we believe to be one of the premier office buildings in Connecticut. All required zoning approvals have been obtained to allow development of an approximately 380,000 rentable square foot office tower and garage. We intend to develop this site when we deem the appropriate combination of market and other conditions are in place.

•

Proactively Manage Our Portfolio. We believe our proactive, service-intensive approach to asset and property management helps increase occupancy and rental rates. We utilize our comprehensive building management services and our strong commitment to tenant and broker relationships and satisfaction to negotiate attractive leasing deals and to attract high credit-quality tenants. We proactively manage our rent roll and maintain continuous communication with our tenants. We foster strong tenant relationships by being responsive to tenant needs. We do this through the amenities we provide, the quality of our buildings and services, our employee screening and training, energy efficiency initiatives, and preventative maintenance and prompt repairs. Our attention to detail is integral to serving our clients and building our brand. Our properties have received numerous industry awards for their operational efficiency. We believe long-term tenant relationships will improve our operating results over time by reducing leasing, marketing and tenant improvement costs and reducing tenant turnover. We do extensive diligence on our tenants’ (current and prospective) balance sheets, businesses and business models to determine if we will establish long-term relationships in which they will both renew with us and expand over time.

Leasing

We are focused on maintaining a brand that tenants associate with a consistently high level of quality of services, installations, maintenance and amenities with long term financial stability. Through our commitment to brokers, we have developed long-term relationships that focus on negotiating attractive transactions with high credit-quality tenants. We proactively manage and cultivate our industry relationships and make the most senior members of our management team available to our constituencies. We believe that our consistent, open dialogue with our tenants and brokers enables us to maximize our redevelopment and repositioning opportunities. Our focus on performance and perspective allows us to concentrate on the ongoing management of our portfolio, while seeking opportunities for growth in the future.

Property Management

We protect our investments by regularly monitoring our properties, performing routine preventive maintenance, and implementing capital improvement programs in connection with property redevelopment and life cycle replacement of equipment and systems. We presently self-manage all of our properties. We proactively manage our properties and rent rolls to (i) aggregate smaller demised spaces to create large blocks of vacant space, to attract high credit-quality tenants at higher rental rates, and (ii) create efficient, modern, pre-built offices that can be rented through several lease cycles and attract better credit-quality tenants. We aggressively manage and control operating expenses at all of our properties. In addition, we have made energy efficiency retrofitting and sustainability a portfolio-wide initiative driven by economic return. We pass on the cost savings achieved by such improvements to our tenants through lower utility costs and reduced operating expense escalations. We believe these initiatives make our properties more desirable to a broader tenant base than the properties of our competitors.

Business Segments

Our reportable segments consist of a real estate segment and an observatory segment. Our real estate segment includes all activities related to the ownership, management, operation, acquisition, repositioning and disposition of our real estate assets. Our observatory segment operates the 86th and 102nd floor observatories at the Empire State Building. These two lines of businesses are managed separately because each business requires different support infrastructures, provides different services and has dissimilar economic characteristics such as investments needed, stream of revenues and different marketing strategies. We account for intersegment sales and transfers as if the sales or transfers were to third parties, that is, at current market prices. We include our construction operation in "Other" and it includes all activities related to providing construction services to tenants and to other entities within and outside our company. As of March 27, 2015, we no longer solicited new business for our construction management business. We completed all projects that were in progress. See Note 14 to our consolidated financial statements for further information on our reportable segments.

Regulation

General

The properties in our portfolio are subject to various laws, ordinances and regulations, including regulations relating to common areas. We believe each of the existing properties has the necessary permits and approvals to operate its business.

Americans with Disabilities Act

Our properties must comply with Title III of the Americans with Disabilities Act, or ADA, to the extent that such properties are “public accommodations” as defined by the ADA. The ADA may require removal of structural barriers to access by persons with disabilities in certain public areas of our properties where such removal is readily achievable. We believe the existing properties are in substantial compliance with the ADA and that we will not be required to make substantial capital expenditures to address the requirements of the ADA. However, noncompliance with the ADA could result in imposition of fines or an award of damages to private litigants. The obligation to make readily achievable accommodations is an ongoing one, and we will continue to assess our properties and to make alterations as appropriate in this respect.

Environmental Matters

Under various federal, state and/or local laws, ordinances and regulations, as a current or former owner or operator of real property, we may be liable for costs and damages resulting from the presence or release of hazardous substances, waste, or petroleum products at, on, in, under or from such property, including costs for investigation or remediation, natural resource damages, or third party liability for personal injury or property damage. These laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the presence or release of such materials, and the liability may be joint and several. Some of our properties have been or may be impacted by contamination arising from current or prior uses of the property or adjacent properties for commercial, industrial or other purposes. Such contamination may arise from spills of petroleum or hazardous substances or releases from tanks used to store such materials. We also may be liable for the costs of remediating contamination at off-site disposal or treatment facilities when we arrange for disposal or treatment of hazardous substances at such facilities, without regard to whether we comply with environmental laws in doing so. The presence of contamination or the failure to remediate contamination on our properties may adversely affect our ability to attract and/or retain tenants, and our ability to develop or sell or borrow against those properties. In addition to potential liability for cleanup costs, private plaintiffs may bring claims for personal injury, property damage or for similar reasons. Environmental laws also may create liens on contaminated sites in favor of the government for damages and costs it incurs to address such contamination. Moreover, if contamination is discovered on our properties, environmental laws may impose restrictions on the manner in which that property may be used or how businesses may be operated on that property.

Some of our properties are adjacent to or near other properties used for industrial or commercial purposes or that have contained or currently contain underground storage tanks used to store petroleum products or other hazardous or toxic substances. Releases from these properties could impact our properties. In addition, some of our properties have previously been used by former owners or tenants for commercial or industrial activities, e.g., gas stations and dry cleaners, and a portion of the Metro Tower site is currently used for automobile parking and fueling, that may release petroleum products or other hazardous or toxic substances at such properties or to surrounding properties. While certain properties contain or contained uses that could have or have impacted our properties, we are not aware of any liabilities related to environmental contamination that we believe will have a material adverse effect on our operations.

Soil contamination has been identified at 69-97 Main Street in Westport, Connecticut. The affected soils are more than four feet below the ground surface. An Environmental Land Use Restriction has been imposed on this site to ensure the soil is not exposed, excavated or disturbed such that it could create a risk of migration of pollutants or a potential hazard to human health or the environment. While the contamination is currently contained, the potential resale value of this property and our ability to finance or refinance this property in the future may be adversely affected as a result of such contamination. In addition, pursuant to the Environmental Land Use Restriction, plans for the redevelopment of the property would be subject to the review of the Town of Westport, Connecticut among other conditions.

The property situated at 500 Mamaroneck Avenue in Harrison, New York was the subject of a voluntary remedial action work cleanup plan performed by the former owner following its conveyance of title to the present owners under an agreement with the New York State Department of Environmental Conservation, or NYDEC. As a condition to the issuance of a “no further action” letter, NYDEC required that certain restrictive and affirmative covenants be recorded against the subject property. In substantial part, these include prohibition against construction that would disturb the soil cap isolating certain contaminated subsurface soil, limiting the use of such property to commercial uses, implementing engineering controls to assure that improvements be kept in good condition, not using ground water at the site for potable purposes without treatment, implementing safety procedures for workers to follow excavating at the site to protect their health and safety and filing an annual certification that the controls implemented in accordance with the voluntary remedial action work cleanup plan remain in place. Furthermore, a substantial portion of the site that had been substantially unimproved prior to acquisition may not be further developed.

In addition, our properties are subject to various federal, state and local environmental and health and safety laws and regulations. Noncompliance with these environmental and health and safety laws and regulations could subject us or our tenants to liability. These liabilities could affect a tenant’s ability to make rental payments to us. Moreover, changes in laws could increase the potential costs of compliance with such laws and regulations or increase liability for noncompliance. This may result in significant unanticipated expenditures or may otherwise materially and adversely affect our operations, or those of our tenants, which could in turn have a material adverse effect on us. We sometimes require our tenants to comply with environmental and health and safety laws and regulations and to indemnify us for any related liabilities in our leases with them. But in the event of the bankruptcy or inability of any of our tenants to satisfy such obligations, we may be required to satisfy such obligations. We are not presently aware of any instances of material non-compliance with environmental or health and safety laws or regulations at our properties, and we believe that we and/or our tenants have all material permits and approvals necessary under current laws and regulations to operate our properties.

As the owner or operator of real property, we may also incur liability based on various building conditions. For example, buildings and other structures on properties that we currently own or operate or those we acquire or operate in the future contain, may contain, or may have contained, asbestos-containing material, or ACM. Environmental and health and safety laws require that ACM be properly managed and maintained and may impose fines or penalties on owners, operators or employers for non-compliance with those requirements. These requirements include special precautions, such as removal, abatement or air monitoring, if ACM would be disturbed during maintenance, redevelopment or demolition of a building, potentially resulting in substantial costs. In addition, we may be subject to liability for personal injury or property damage sustained as a result of releases of ACM into the environment. We are not presently aware of any material liabilities related to building conditions, including any instances of material non-compliance with asbestos requirements or any material liabilities related to asbestos.

presence of significant mold or other airborne contaminants at any of our properties could require us to undertake a costly remediation program to contain or remove the mold or other airborne contaminants from the affected property or increase indoor ventilation. In addition, the presence of significant mold or other airborne contaminants could expose us to liability from our tenants, employees of our tenants or others if property damage or personal injury occurs. We are not presently aware of any material adverse indoor air quality issues at our properties.

Insurance

We carry comprehensive liability, fire, extended coverage, earthquake, terrorism and rental loss insurance covering all of our Manhattan properties and our greater New York metropolitan area properties under a blanket policy. We carry additional all-risk property and business insurance, which includes terrorism insurance, on the Empire State Building through ESRT Captive Insurance Company L.L.C., or ESRT Captive Insurance, our wholly owned captive insurance company. ESRT Captive Insurance covers terrorism insurance for $800 million in losses in excess of $800 million per occurrence suffered by the Empire State Building, providing us with aggregate terrorism coverage of $1.6 billion at that property. ESRT Captive Insurance fully reinsures the 15% coinsurance under the Terrorism Risk Insurance Program Reauthorization Act of 2015 (TRIPRA) and the difference between the TRIPRA captive deductible and policy deductible of $25,000 for non-Nuclear, Biological, Chemical and Radiological exposures. As a result, we remain only liable for the 15% coinsurance under TRIPRA for Nuclear, Biological, Chemical and Radiological (NBCR) exposures, as well as a deductible equal to 20% of the prior year’s premium. As long as we own ESRT Captive Insurance, we are responsible for ESRT Captive Insurance’s liquidity and capital resources, and ESRT Captive Insurance’s accounts are part of our consolidated financial statements. If we experience a loss and our captive insurance company is required to pay under its insurance policy, we would ultimately record the loss to the extent of its required payment. The policies described above cover certified terrorism losses as defined under the Terrorism Risk Insurance Act of 2002 (TRIA) and subsequent extensions. On January 12, 2015, the President of the United States signed into law TRIPRA, which extends TRIA through December 31, 2020. TRIA provides for a system of shared public and private compensation for insured losses resulting from acts of terrorism. As a result, the certified terrorism coverage provided by ESRT Captive Insurance is eligible for 85% coinsurance provided by the United States Treasury in excess of a statutorily calculated deductible. ESRT Captive Insurance reinsures 100% of their 15% coinsurance for non-NBCR exposures. The 15% coinsurance on NBCR exposures is retained by ESRT Captive Insurance.

TRIA was not in effect for the period from January 1, 2015 through January 11, 2015. During this brief period of time, we carried a reduced terrorism insurance limit, which we believed was commercially acceptable under the circumstances.

Reinsurance contracts do not relieve ESRT Captive Insurance from its primary obligations to its policyholders. Additionally, failure of the various reinsurers to honor their obligations could result in significant losses to ESRT Captive Insurance. The reinsurance has been ceded to reinsurers approved by the State of Vermont. ESRT Captive Insurance continually evaluates the reinsurers’ financial condition by considering published financial stability ratings of the reinsurers and other factors. There can be no assurance that reinsurance will continue to be available to ESRT Captive Insurance to the same extent and at the same cost. ESRT Captive Insurance may choose in the future to reevaluate the use of reinsurance to increase or decrease the amounts of risk it cedes.

In addition to insurance held through our captive insurance company described above, we carry terrorism insurance on all of our properties in an amount and with deductibles which we believe are commercially reasonable.

Competition

The leasing of real estate is highly competitive in Manhattan and the greater New York metropolitan market in which we operate. We compete with numerous acquirers, developers, owners and operators of commercial real estate, many of which own or may seek to acquire or develop properties similar to ours in the same markets in which our properties are located. The principal means of competition are rent charged, location, services provided and the nature and condition of the facility to be leased. In addition, we face competition from other real estate companies including other REITs, private real estate funds, domestic and foreign financial institutions, life insurance companies, pension trusts, partnerships, individual investors and others that may have greater financial resources or access to capital than we do or that are willing to acquire properties in transactions which are more highly leveraged or are less attractive from a financial viewpoint than we are willing to pursue. In addition, competition from observatory and/or broadcasting operations at One World Trade Center and, to a lesser extent, from the observatory at Rockefeller Center and the broadcasting facility at Four Times Square, could have a negative impact on revenues from our observatory operations and/or broadcasting revenues. Adverse impacts on domestic travel and changes in foreign currency exchange rates may also decrease demand in the future, which could have a material adverse effect on our results of operations, financial condition and ability to make distributions to our securityholders. If our competitors offer space at rental rates below current market rates, below the rental rates we currently charge our tenants, in better locations within our

markets or in higher quality facilities, we may lose potential tenants and we may be pressured to reduce our rental rates below those we currently charge in order to retain tenants when our tenants’ leases expire.

ESRT's Tax Status as a REIT

ESRT elected to be taxed as a REIT and operate in a manner that we believe allows it to qualify as a REIT for federal income tax purposes commencing with its taxable year ended December 31, 2013. We believe that ESRT has been organized in conformity with the requirements for qualification and taxation as a REIT under the Internal Revenue Code of 1986, as amended (the "Code"), and that its intended manner of operation will enable it to meet the requirements for qualification and taxation as a REIT. So long as ESRT qualifies as a REIT, it generally will not be subject to U.S. federal income tax on its net taxable income that ESRT distributes currently to its securityholders. If ESRT fails to qualify as a REIT in any taxable year and does not qualify for certain statutory relief provisions, ESRT will be subject to U.S. federal income tax at regular corporate rates and may be precluded from qualifying as a REIT for the subsequent four taxable years following the year during which it lost its REIT qualification. Even if ESRT qualifies for taxation as a REIT, it may be subject to certain U.S. federal, state and local taxes on its income or property.

Inflation

Substantially all of our leases provide for separate real estate tax and operating expense escalations. In addition, many of the leases provide for fixed base rent increases. We believe inflationary increases may be at least partially offset by the contractual rent increases and expense escalations described above. We do not believe inflation has had a material impact on our historical financial position or results of operations.

Seasonality

Our observatory business is subject to tourism trends and weather, and therefore does experience some seasonality. During the past ten years of our annual observatory revenue, approximately 16% to 18% was realized in the first quarter, 26.0% to 28.0% was realized in the second quarter, 31.0% to 33.0% was realized in the third quarter and 23.0% to 25.0% was realized in the fourth quarter. We do not consider the balance of our business to be subject to material seasonal fluctuations.

Employees

As of December 31, 2015, we had approximately 850 employees, 148 of whom were managers and professionals. There are currently collective bargaining agreements which cover the workforce that services all of our office properties.

Offices

Our principal executive offices are located at One Grand Central Place, 60 East 42^nd Street, New York, New York 10165. In addition, we have six additional regional leasing and property management offices in Manhattan and the greater New York metropolitan area. Our current facilities are adequate for our present and future operations, although we may add regional offices or relocate our headquarters, depending upon our future operations.

ITEM 1A. RISK FACTORS

RISK FACTORS

You should carefully consider these risk factors, together with all of the other information included in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes thereto, before you decide whether to make an investment in our securities. The risks set out below are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, prospects, financial condition, cash flows, liquidity, funds from operations, results of operations, price of our securities and the shares of ESRT's Class A common stock, ability to service our indebtedness, and/or ability to make cash distributions to our securityholders (including those necessary to maintain ESRT’s REIT qualification). In such case, the value of our securities and the trading price of our traded OP units could decline, and you may lose all or a significant part of your investment. Some statements in the following risk factors, constitute forward looking statements. See the section entitled “Forward-Looking Statements.”

Risks Related to Our Properties and Our Business

All of our properties are located in Manhattan and the greater New York metropolitan area, in particular midtown Manhattan, and adverse economic or regulatory developments in this area could materially and adversely affect us.

All of our properties are located in Manhattan and the greater New York metropolitan area, in particular midtown Manhattan, as well as nearby markets in Fairfield County, Connecticut and Westchester County, New York. Nine of our 14 office properties are located in midtown Manhattan. As a result, our business is dependent on the condition of the New York City economy in general and the market for office space in midtown Manhattan in particular, which exposes us to greater economic risks than if we owned a more geographically diverse portfolio. We are susceptible to adverse developments in the New York City economic and regulatory environment (such as business layoffs or downsizing, industry slowdowns, relocations of businesses, increases in real estate and other taxes, costs of complying with governmental regulations or increased regulation). Such adverse developments could materially reduce the value of our real estate portfolio and our rental revenues, and thus materially and adversely affect our ability to service current debt and to pay distributions to securityholders. We could also be impacted by adverse developments in the Fairfield County, Connecticut and Westchester County, New York markets. We cannot assure you that these markets will grow or that underlying real estate fundamentals will be favorable to owners and operators of office or retail properties. Our operations may also be affected if competing properties are built in either of these markets.

Adverse economic and geopolitical conditions in general and in Manhattan and the greater New York metropolitan area commercial office and retail markets in particular, could have a material adverse effect on our results of operations, financial condition, ability to service debt and our ability to make distributions to our securityholders.

Our business may be affected by the volatility and illiquidity in the financial and credit markets, a general global economic recession and other market or economic challenges experienced by the real estate industry or the U.S. economy as a whole. Our business may also be materially and adversely affected by local economic conditions, as substantially all of our revenues are derived from our properties located in Manhattan and the greater New York metropolitan area, particularly in Manhattan, Fairfield County and Westchester County. Because our portfolio consists primarily of commercial office and retail buildings (as compared to a more diversified real estate portfolio) located principally in Manhattan, if economic conditions persist or deteriorate, then our results of operations, financial condition, ability to service current debt and to make distributions to our securityholders may be materially and adversely affected by the following, among other potential conditions:


•	the financial condition of our tenants, many of which are consumer goods, financial, legal and other professional firms, may be adversely affected, which may result in tenant defaults under leases due to bankruptcy, lack of liquidity, operational failures or other reasons;


•	significant job losses in the financial and professional services industries have occurred and may continue to occur, which may decrease demand for our office space, causing market rental rates and property values to be impacted negatively;

•

our ability to borrow on terms and conditions that we find acceptable, or at all, may be limited, which could reduce our ability to pursue acquisition and development opportunities, engage in our redevelopment and repositioning activities and refinance existing debt, reduce our returns from both our existing operations and our acquisition and development activities and increase our future interest expense;


•	reduced values of our properties may limit our ability to dispose of assets at attractive prices or to obtain debt financing secured by our properties and may reduce the availability of unsecured loans;


•	reduced liquidity in debt markets and increased credit risk premiums for certain market participants may impair our ability to access capital or make such access more expensive; and

•

the value and liquidity of our short-term investments and cash deposits could be reduced as a result of a deterioration of the financial condition of the institutions that hold our cash deposits or the institutions or assets in which we have made short-term investments, the dislocation of the markets for our short-term investments, increased volatility in market rates for such investments or other factors.

These conditions may continue or worsen in the future, which could materially and adversely affect our results of operations, financial condition and ability to make distributions to our securityholders.

There can be no assurance that our redevelopment and repositioning program will be completed in its entirety in accordance with the anticipated timing or at the anticipated cost, or that we will achieve the results we expect from our redevelopment and repositioning program, which could materially and adversely affect our financial condition and results of operations.

We have been undertaking a comprehensive redevelopment and repositioning program of our Manhattan office properties that has included the physical improvement through upgrades and modernization of, and tenant upgrades in, such properties. We currently estimate that between $30.0 million and $50.0 million of capital is needed primarily in 2016 to complete substantially the redevelopment and repositioning program of our Manhattan office properties, which we expect to occur by the end of 2016. These estimates are based on our current budgets (which do not include tenant improvements and leasing commissions) and may be less than our actual costs. We may experience conditions which delay or preclude program completion. In addition, we may not be able to lease available space on favorable terms or at all. Further, our redevelopment and repositioning program may lead to temporary increased vacancy rates at the properties undergoing redevelopment. There can be no assurance that our redevelopment and repositioning program will be completed in its entirety in accordance with the anticipated timing or at the anticipated cost, or that we will achieve the results we expect from our redevelopment and repositioning program or that we will be able to achieve anticipated results which could materially and adversely affect our financial condition and results of operations.

We rely on five properties for a significant portion of our rental revenue.

For the year ended December 31, 2015, five of our properties, the Empire State Building, One Grand Central Place, 111 West 33^rd Street (formerly known as 112 West 34th Street), 1400 Broadway and First Stamford Place together accounted for approximately 66.2% of our portfolio’s rental revenues, and no other property accounted for more than approximately 5.0% of our portfolio’s rental revenues. For the year ended December 31, 2015, the Empire State Building individually accounted for approximately 31.4% of our portfolio’s rental revenues. Our revenue and cash available for distribution to our securityholders would be materially and adversely affected if the Empire State Building, One Grand Central Place, 111 West 33rd Street (formerly known as 112 West 34th Street), 1400 Broadway or First Stamford Place were materially damaged or destroyed. Additionally, our revenue and cash available for distribution to our securityholders would be materially adversely affected if a significant number of our tenants at these properties experienced a downturn in their business which may weaken their financial condition and result in their failure to make timely rental payments, defaulting under their leases or filing for bankruptcy.

The observatory operations at the Empire State Building are not traditional real estate operations, and competition and changes in tourist trends may subject us to additional risks, which could materially and adversely affect us.

During the year ended December 31, 2015, we derived approximately $112.2 million of revenue from the Empire State Building’s observatory operations, representing approximately 38.7% of the Empire State Building’s total revenue for this period. Demand for our observatory is highly dependent on domestic and overseas tourists. In addition, competition from observatory operations at One World Trade Center and, to a lesser extent, from the observatory at Rockefeller Center, could have a negative impact on revenues from our observatory operations which could have a material adverse effect on our results of operations, financial condition and ability to make distributions to our securityholders. Adverse impacts on domestic travel and changes in foreign currency exchange rates may also decrease demand in the future, which could have a material adverse effect on our results of operations, financial condition and ability to make distributions to our securityholders.

We may be unable to renew leases, lease vacant space or re-lease space on favorable terms or at all as leases expire, which could materially and adversely affect our financial condition, results of operations and cash flow.

As of December 31, 2015, we had approximately 1.1 million rentable square feet of vacant space (excluding leases signed but not yet commenced). In addition, leases representing 7.7% and 7.3% of the square footage of the properties in our portfolio will expire in 2016 and 2017, respectively (including month to month leases). We cannot assure you that expiring leases will be renewed or that our properties will be re-leased at net effective rental rates equal to or above the current average net effective rental rates. Above-market rental rates at some of the properties in our portfolio may force us to renew some expiring leases or re-lease properties at lower rates. If the rental rates of our properties decrease, our existing tenants do not renew their leases or we do not re-lease a significant portion of our available space and space for which leases will expire, our financial condition, results of operations, cash flow, per share/unit trading price of ESRT's Class A common stock and our

traded OP units and our ability to satisfy our principal and interest obligations and to make distributions to our securityholders would be materially and adversely affected.

The actual rents we receive for the properties in our portfolio may be less than our asking rents, and we may experience a decline in realized rental rates from time to time, which could materially and adversely affect our financial condition, results of operations and cash flow.

As a result of various factors, including competitive pricing pressure in our markets, a general economic downturn and the desirability of our properties compared to other properties in our markets, we may be unable to realize our asking rents across the properties in our portfolio. In addition, the degree of discrepancy between our asking rents and the actual rents we are able to obtain may vary both from property to property and among different leased spaces within a single property. If we are unable to obtain sufficient rental rates across our portfolio, then our ability to generate cash flow growth will be negatively impacted. In addition, depending on market rental rates at any given time as compared to expiring leases in our portfolio, from time to time rental rates for expiring leases may be higher than starting rental rates for new leases.

We are exposed to risks associated with property redevelopment and development that could materially and adversely affect our financial condition and results of operations.

We have engaged, and continue to engage, in development and redevelopment activities with respect to our Manhattan office properties. In addition, we own entitled land at the Stamford Transportation Center in Stamford, Connecticut that can support the development of an approximately 380,000 rentable square foot office building and garage. To the extent that we continue to engage in development and redevelopment activities, we will be subject to certain risks, including, without limitation:


•	the availability and pricing of financing on favorable terms or at all;


•	the availability and timely receipt of zoning and other regulatory approvals;


•	the potential for the fluctuation of occupancy rates and rents at properties due to a number of factors, including market and economic conditions, which may result in our investment not being profitable;


•	start up, repositioning and redevelopment costs may be higher than anticipated;


•	the cost and timely completion of construction (including risks beyond our control, such as weather or labor conditions, or material shortages);


•	the potential that we may fail to recover expenses already incurred if we abandon development or redevelopment opportunities after we begin to explore them;


•	the potential that we may expend funds on and devote management time to projects which we do not complete;


•	the inability to complete construction and leasing of a property on schedule, resulting in increased debt service expense and construction or redevelopment costs; and


•	the possibility that properties will be leased at below expected rental rates.

These risks could result in substantial unanticipated delays or expenses and, under certain circumstances, could prevent the initiation of development and redevelopment activities or the completion of development and redevelopment activities once undertaken, any of which could have an adverse effect on our financial condition, results of operations, cash flow, per share/unit trading price of ESRT's Class A common stock and our traded OP units and ability to satisfy our principal and interest obligations and to make distributions to our securityholders.

We may be required to make rent or other concessions and/or significant capital expenditures to improve our properties in order to retain and attract tenants, which could materially and adversely affect us, including our financial condition, results of operations and cash flow.

To the extent there are adverse economic conditions in the real estate market and demand for office space decreases, upon expiration of leases at our properties and with respect to our current vacant space, we will be required to increase rent or other concessions to tenants, accommodate increased requests for renovations, build-to-suit remodeling and other improvements or provide additional services to our tenants. In addition, eight of our existing properties are pre-war office properties, which may require more frequent and costly maintenance to retain existing tenants or attract new tenants than newer properties. As a result, we would have to make significant capital or other expenditures in order to retain tenants whose leases expire and to attract new tenants in sufficient numbers. Additionally, we may need to raise capital to make such expenditures. If we are unable to do so or capital is otherwise unavailable, we may be unable to make the required expenditures. This could result in non-renewals by tenants upon expiration of their leases and our vacant space remaining untenanted, which could materially and adversely affect our financial condition, results of operations, cash flow and per share/unit trading price of ESRT's Class A common stock and our traded OP units. As of December 31, 2015, we had approximately 1.1 million rentable square feet of vacant space (excluding leases signed but not yet commenced), and leases representing 7.7% and 7.3% of the square footage of the properties in our portfolio will expire in the in 2016 and 2017, respectively (including month to month leases).

We depend on significant tenants in our office portfolio, including Global Brands Group, Coty, Inc., PVH Corp., Thomson Reuters and LinkedIn, which together represented approximately 15.6% of our total portfolio’s annualized rent as of December 31, 2015.

As of December 31, 2015, our five largest tenants together represented 15.6% of our total portfolio’s annualized rent. Our largest tenant is Global Brands Group. As of December 31, 2015, Global Brands Group leased an aggregate of 0.7 million rentable square feet of office space at three of our office properties, representing approximately 6.5% of the total rentable square feet and approximately 6.4% of the annualized rent in our portfolio. Our rental revenue depends on entering into leases with and collecting rents from tenants. General and regional economic conditions, such as the current challenging economic climate described above, may adversely affect our major tenants and potential tenants in our markets. Our major tenants may experience a material business downturn, weakening their financial condition and potentially resulting in their failure to make timely rental payments and/or a default under their leases. In many cases, we have made substantial up front investments in the applicable leases, through tenant improvement allowances and other concessions, as well as typical transaction costs (including professional fees and commissions) that we may not be able to recover. In the event of any tenant default, we may experience delays in enforcing our rights as landlord and may incur substantial costs in protecting our investment.

The bankruptcy or insolvency of a major tenant also may adversely affect the income produced by our properties. If any tenant becomes a debtor in a case under the United States Bankruptcy Code of 1978, as amended, we cannot evict the tenant solely because of the bankruptcy. In addition, the bankruptcy court might authorize the tenant to reject and terminate their lease with us. The bankruptcy of a tenant or lease guarantor could delay our efforts to collect past due balances under the relevant leases, and could ultimately preclude collection of these sums. If a lease is rejected by a tenant in bankruptcy, we would have only a general unsecured claim for damages. Any unsecured claim we hold may be paid only to the extent that funds are available and only in the same percentage as is paid to all other holders of unsecured claims, and there are restrictions under bankruptcy laws that limit the amount of the claim we can make if a lease is rejected.

Our revenue and cash flow could be materially adversely affected if any of our significant tenants were to become bankrupt or insolvent, or suffer a downturn in their business, default under their leases or fail to renew their leases at all or renew on terms less favorable to us than their current terms.

Competition may impede our ability to attract or retain tenants or re-let space, which could materially and adversely affect our results of operations and cash flow.

The leasing of real estate in the greater New York metropolitan area is highly competitive. The principal means of competition are rent charged, location, services provided and the nature and condition of the premises to be leased. We directly compete with all lessors and developers of similar space in the areas in which our properties are located as well as properties in other submarkets. Demand for retail space may be impacted by the bankruptcy of retail companies, a general trend toward consolidation in the retail industry, and the impact of internet retailing which could adversely affect the ability of our company to attract and retain tenants. In addition, retailers at our properties face increasing competition from outlet malls, discount shopping clubs, electronic commerce, direct mail and telemarketing, which could (i) reduce rents payable to us, (ii) reduce our ability to attract and retain tenants at our properties and (iii) lead to increased vacancy rates at our properties, any of which could materially and adversely affect us.

Our office properties are concentrated in highly developed areas of midtown Manhattan and densely populated metropolitan communities in Fairfield County and Westchester County. Manhattan is the largest office market in the United States. The number of competitive office properties in the markets in which our properties are located (which may be newer or better located than our properties) could have a material adverse effect on our ability to lease office space at our properties, and on the effective rents we are able to charge.

If our tenants are unable to secure financing necessary to continue to operate their businesses and pay us rent, we could be materially and adversely affected.

Many of our tenants rely on external sources of financing to operate their businesses. If our tenants are unable to secure financing necessary to continue to operate their businesses, they may be unable to meet their rent obligations or be forced to declare bankruptcy and reject their leases, which could materially and adversely affect us.

Our dependence on smaller businesses to rent our office space could materially and adversely affect our cash flow and results of operations.

The majority of the tenants in our properties (measured by number of tenants as opposed to aggregate square footage) are smaller businesses that generally do not have the financial strength of larger corporate tenants. Smaller companies generally experience a higher rate of failure than large businesses. There is a current risk with these companies of a higher rate of tenant defaults, turnover and bankruptcies, which could materially and adversely affect our distributable cash flow and results of operations.

Our dependence on rental income may materially and adversely affect our cash flow and results of operations.

A substantial portion of our income is derived from rental income from real property. As a result, our performance depends on our ability to collect rent from tenants. Our income and funds for distribution would be negatively affected if a significant number of our tenants, or any of our major tenants (as discussed in more detail below):


•	delay lease commencements;


•	decline to extend or renew leases upon expiration;


•	fail to make rental payments when due; or


•	declare bankruptcy.

Any of these actions could result in the termination of the tenants’ leases and the loss of rental income attributable to the terminated leases. In these events, we cannot be sure that any tenant whose lease expires will renew that lease or that we will be able to re-lease space on economically advantageous terms or at all. The loss of rental revenues from a number of our tenants and our inability to replace such tenants may adversely affect our profitability, our ability to meet debt and other financial obligations and our ability to make distributions to our securityholders.

The broadcasting operations at the Empire State Building are not traditional real estate operations, and competition and changes in the broadcasting of signals over air may subject us to additional risks, which could materially and adversely affect us.

The Empire State Building and its broadcasting mast provides radio and data communications services and supports delivery of broadcasting signals to cable and satellite systems and television and radio receivers. We license the use of the broadcasting mast to third party television and radio broadcasters. During the year ended December 31, 2015, we derived approximately $20.9 million, of revenue (excluding tenant reimbursement income) from the Empire State Building’s broadcasting licenses and related leased space, representing approximately 7.2% of the Empire State Building’s total revenue for this period. Competition from broadcasting operations at One World Trade Center and, to a lesser extent, from the broadcasting operations at Four Times Square, could have a negative impact on revenues from our broadcasting operations, and require lease renewal proposals which could yield reduced revenue, higher operating expenses and/ or higher capital expenditures. Our broadcast television and radio licensees also face a range of competition from advances in technologies and alternative methods of content delivery in their respective industries, as well as from changes in consumer behavior driven by new technologies and methods of content delivery, which may reduce the demand for over-the-air broadcast licenses in the future. New government regulations affecting broadcasters, including the implementation of the Federal Communications Commission's (the "FCC") National Broadband Plan, (the "FCC Plan"), also might materially and adversely affect our results of operations by reducing the demand for broadcast licenses. Among other things, the FCC Plan urges Congress to make more spectrum available for wireless broadband service providers by encouraging over-the-air broadcast licensees to relinquish spectrum through a voluntary auction process, which raises many issues that could impact the broadcast industry. At this time we cannot predict whether Congress or the FCC will adopt or implement any of the FCC Plan’s recommendations or the rule changes as proposed, or how any such actions might affect our broadcasting operations. Any of these risks might materially and adversely affect us.

We may not be able to control our operating costs, or our expenses may remain constant or increase, even if income from our properties decreases, causing our results of operations to be adversely affected.

Our financial results depend substantially on leasing space in our properties to tenants on terms favorable to us. Costs associated with real estate investment, such as real estate taxes, insurance and maintenance costs, generally are not reduced even when a property is not fully occupied, rental rates decrease or other circumstances cause a reduction in income from the property. As a result, cash flow from the operations of our properties may be reduced if a tenant does not pay its rent or we are unable to rent our properties on favorable terms. Under those circumstances, we might not be able to enforce our rights as landlord without delays and may incur substantial legal costs. The terms of our leases may also limit our ability to charge our tenants for all or a portion of these expenses. Additionally, new properties that we may acquire or redevelop may not produce significant revenue immediately, and the cash flow from existing operations may be insufficient to pay the operating expenses and principal and interest on debt associated with such properties until they are fully leased.

Our breach of or the expiration of our ground leases could materially and adversely affect our results of operations.

Our interest in three of our commercial office properties, 1350 Broadway, 111 West 33rd Street (formerly known as 112 West 34th Street) and 1400 Broadway are long-term leaseholds of the land and the improvements, rather than a fee interest in the land and the improvements. If we are found to be in breach of these ground leases, we could lose the right to use the properties. In addition, unless we purchase the underlying fee interest in these properties or extend the terms of our leases for these properties before expiration on terms significantly comparable to our current leases, we will lose our right to operate these properties and our leasehold interests in these properties upon expiration of the leases or we will continue to operate them at much lower profitability, which would significantly adversely affect our results of operations. In addition, if we are perceived to have breached the terms of these leases, the fee owner may initiate proceedings to terminate the leases. The long-term leases, including unilateral extension rights available to us, expire, on July 31, 2050 for 1350 Broadway, December 31, 2063 for 1400 Broadway and June 10, 2077 for 111 West 33rd Street (formerly known as 112 West 34th Street).

Pursuant to the ground leases, we, as tenant under the ground leases, perform the functions traditionally performed by owners, as landlords, with respect to our subtenants. In addition to collecting rent from our subtenants, we also maintain the properties and pay expenses relating to the properties. We do not have a right, pursuant to the terms of our leases or otherwise, to acquire the fee interests in these properties.

We will not recognize any increase in the value of the land or improvements subject to our ground leases, and we may only receive a portion of compensation paid in any eminent domain proceeding with respect to these properties, which could materially and adversely affect us.

We have no economic interest in the land or improvements at the expiration of our ground leases at 1350 Broadway, 111 West 33rd Street (formerly known as 112 West 34th Street) and 1400 Broadway, and therefore we will not share in any increase in value of the land or improvements beyond the term of our ground leases, notwithstanding our capital outlay to purchase our interest in the properties. Furthermore, if the state or federal government seizes the properties subject to the ground leases under its eminent domain power, we may only be entitled to a portion of any compensation awarded for the seizure. In addition, if the value of the properties has increased, it may be more expensive for us to renew our ground leases.

We may be unable to identify and successfully complete acquisitions and even if acquisitions are identified and completed, we may fail to operate successfully acquired properties, which could materially and adversely affect us and impede our growth.

Our current portfolio consists entirely of properties that we acquired (or received the right to acquire) in connection with the formation transactions. Our ability to identify and acquire additional properties on favorable terms and successfully operate or redevelop them may be exposed to the following significant risks:

•

even if we enter into agreements for the acquisition of properties, these agreements are subject to customary conditions to closing, including completion of due diligence investigations to our satisfaction and other conditions that are not within our control, which may not be satisfied, and we may be unable to complete an acquisition after making a non-refundable deposit and incurring certain other acquisition-related costs;


•	we may be unable to finance the acquisition on favorable terms in the time period we desire, or at all;


•	we may spend more than budgeted to make necessary improvements or redevelopments to acquired properties;


•	we may not be able to obtain adequate insurance coverage for new properties;


•	acquired properties may be located in new markets where we may face risks associated with a lack of market knowledge or understanding of the local economy, lack of business relationships in the area and unfamiliarity with local governmental and permitting procedures;


•	we may be unable to integrate quickly and efficiently new acquisitions, particularly acquisitions of portfolios of properties, into our existing operations, and as a result our results of operations and financial condition could be adversely affected;


•	market conditions may result in higher than expected vacancy rates and lower than expected rental rates; and


•	we may incur significant costs and divert management attention in connection with evaluating and negotiating potential acquisitions, including ones that we are subsequently unable to complete.

Any delay or failure on our part to identify, negotiate, finance and consummate such acquisitions in a timely manner and on favorable terms, or operate acquired properties to meet our financial expectations, could impede our growth and adversely affect our financial condition, results of operations, cash flow and per share/unit trading price of ESRT's Class A common stock and our traded OP units.

Competition for acquisitions may reduce the number of acquisition opportunities available to us and increase the costs of those acquisitions, which may impede our growth.

We plan to acquire properties as we are presented with attractive opportunities. We may face significant competition for acquisition opportunities in the greater New York metropolitan area with other investors, particularly private investors who can incur more leverage, and this competition may adversely affect us by subjecting us to the following risks:


•	an inability to acquire a desired property because of competition from other well-capitalized real estate investors, including publicly traded and privately held REITs, private real estate funds, domestic and foreign financial institutions, life insurance companies, sovereign wealth funds, pension trusts, commercial developers, partnerships and individual investors; and


•	an increase in the purchase price for such acquisition property, in the event we are able to acquire such desired property.

The significant competition for acquisitions of commercial office and retail properties in the greater New York metropolitan area may impede our growth.

Acquired properties may expose us to unknown liability, which could adversely affect our results of operations, cash flow and the market value of our securities.

We may acquire properties subject to liabilities and without any recourse, or with only limited recourse, against the prior owners or other third parties with respect to unknown liabilities. As a result, if a liability were asserted against us based upon ownership of those properties, we might have to pay substantial sums to settle or contest it, which could adversely affect our results of operations, cash flow and the market value of our securities. Unknown liabilities with respect to acquired properties might include:


•	liabilities for clean-up of undisclosed environmental contamination;


•	claims by tenants, vendors or other persons against the former owners of the properties;


•	liabilities incurred in the ordinary course of business; and


•	claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties.

We may acquire properties or portfolios of properties through tax deferred contribution transactions, which could result in securityholder dilution and limit our ability to sell such assets.

In the future we may acquire properties or portfolios of properties through tax deferred contribution transactions in exchange for partnership interests in our company, which may result in dilution to securityholders. This acquisition structure may have the effect of, among other things, reducing the amount of tax depreciation we could deduct over the tax life of the acquired properties, and may require that we agree to protect the contributors’ ability to defer recognition of taxable gain through restrictions on our ability to dispose of the acquired properties and/or the allocation of partnership debt to the contributors to maintain their tax bases. These restrictions could limit our ability to sell an asset at a time, or on terms, that would be favorable absent such restrictions.

Should we decide at some point in the future to expand into new markets, we may not be successful, which could adversely affect our financial condition, result of operations, cash flow and trading price of ESRT's Class A common stock and our traded OP units.

If opportunities arise, we may explore acquisitions of properties in new markets. Each of the risks applicable to our ability to acquire and integrate successfully and operate properties in our current markets is also applicable to our ability to acquire and integrate successfully and operate properties in new markets. In addition to these risks, we will not possess the same level of familiarity with the dynamics and market conditions of any new markets that we may enter, which could adversely affect the results of our expansion into those markets, and we may be unable to build a significant market share or achieve a desired return on our investments in new markets. If we are unsuccessful in expanding into new markets, it could adversely affect our financial condition, results of operations, cash flow, trading price of ESRT's Class A common stock and our traded OP units and ability to satisfy our principal and interest obligations and to make distributions to our securityholders.

Our growth depends on external sources of capital that are outside of our control, which may affect our ability to seize strategic opportunities, satisfy debt obligations and make distributions to our securityholders.

In order for ESRT to qualify as a REIT, it must distribute to its securityholders, on an annual basis, at least 90% of its REIT taxable income, determined without regard to the deduction for distributions paid and excluding net capital gains. In addition, it will be subject to U.S. federal income tax at regular corporate rates to the extent that it distributes less than 100% of its net taxable income (including net capital gains) and will be subject to a 4% nondeductible excise tax on the amount by which its distributions in any calendar year are less than a minimum amount specified under U.S. federal income tax laws. Our partnership agreement provides that we will make sufficient distributions to ESRT to enable it to satisfy these distribution requirements and to avoid U.S. federal corporate income tax and the 4% excise tax. Because of these distribution requirements, we may not be able to fund future capital needs, including any necessary acquisition financing, from operating cash flow. Consequently, we may need to rely on third-party sources to fund our capital needs. We may not be able to obtain financing on favorable terms, in the time period we desire, or at all. Any additional debt we incur will increase our leverage. Our access to third-party sources of capital depends, in part, on:


•	general market conditions;


•	the market’s perception of our growth potential;


•	our current debt levels;


•	our current and expected future earnings;


•	our cash flow and cash distributions; and


•	the market price per share/unit of ESRT's Class A common stock and our traded OP units.

If we cannot obtain capital from third-party sources, we may not be able to acquire or redevelop properties when strategic opportunities exist, satisfy our principal and interest obligations or make the cash distributions to our securityholders necessary to maintain ESRT's qualification as a REIT.

If we are unable to sell, dispose of or refinance one or more properties in the future, we may be unable to realize our investment objectives, and our business may be adversely affected.

The real estate investments made, and to be made, by us are relatively difficult to sell quickly. Return of capital and realization of gains from an investment generally will occur upon disposition or refinancing of the underlying property. In addition, the Internal Revenue Code of 1986, as amended (the "Code"), imposes restrictions on the ability of a REIT to dispose of properties that are not applicable to other types of real estate companies, which limit our ability to sell properties without adversely affecting ESRT. We may be unable to realize our investment objectives by sale, other disposition or refinancing at attractive prices within any given period of time or may otherwise be unable to complete any exit strategy. In particular, these risks could arise from weakness in or even the lack of an established market for a property, changes in the financial condition or prospects of prospective purchasers, changes in national or international economic conditions and changes in laws, regulations or fiscal policies of jurisdictions in which our properties are located.

Our outstanding indebtedness reduces cash available for distribution and may expose us to the risk of default under our debt obligations and may include covenants that restrict our financial and operational flexibility and our ability to make distributions.

As of December 31, 2015, our total consolidated indebtedness was approximately $1.6 billion. We may incur significant additional debt to finance future acquisition and redevelopment activities. Payments of principal and interest on borrowings may leave us with insufficient cash resources to operate our properties or to pay the distributions currently contemplated or necessary to allow ESRT to qualify as a REIT. Our level of debt and the limitations imposed on us by our loan documents could have significant adverse consequences, including the following:


•	our cash flow may be insufficient to meet our required principal and interest payments;


•	we may be unable to borrow additional funds as needed or on favorable terms;


•	we may be unable to refinance our indebtedness at maturity or the refinancing terms may be less favorable than the terms of our original indebtedness;


•	to the extent we borrow debt that bears interest at variable rates, increases in interest rates could materially increase our interest expense;


•	we may be forced to dispose of one or more of our properties, possibly on disadvantageous terms;


•	we may default on our obligations or violate restrictive covenants, in which case the lenders or mortgagees may accelerate our debt obligations, foreclose on the properties that secure their loans and/or take control of our properties that secure their loans and collect rents and other property income;


•	we may violate restrictive covenants in our loan documents, which would entitle the lenders to accelerate our debt obligations or reduce our ability to make, or prohibit us from making, distributions; and


•	our default under any one of our mortgage loans with cross default provisions could result in a default on other indebtedness.

In addition, our unsecured revolving credit facility, our Series A, Series B and Series C senior notes and our senior unsecured term loan facility requires us to maintain designated ratios, including but not limited to, total debt-to-assets, secured debt-to-assets, adjusted EBITDA to consolidated fixed charges, net operating income from unencumbered properties to interest expense on unsecured debt, unsecured debt to unencumbered assets and secured recourse debt-to-assets, and contains a minimum tangible net worth requirement. Our unsecured revolving credit facility, our Series A, Series B and Series C senior notes and our senior unsecured term loan facility do not generally contain restrictions on the payment of dividends or other distributions. The indenture governing our outstanding senior unsecured notes, our Series A, Series B and Series C senior notes and our senior unsecured term loan facility do not contain financial or operational covenants or restrictions on the payments of dividends; however, upon the occurrence of fundamental changes described in the indenture, holders of our outstanding senior unsecured notes, our Series A, Series B and Series C senior notes and our senior unsecured term loan facility may require our operating partnership to repurchase for cash all or part of their notes at a repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, subject to certain conditions. Further, upon the occurrence of any make-whole fundamental change described in the indenture, the exchange rate for holders who exchange their notes in connection with any such make-whole fundamental change may be increased. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources."

The provisions in the partnership agreement of our operating partnership that govern the preferred units may restrict our ability to pay dividends if we fail to pay the cumulative preferential cash distributions thereon. See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Private Perpetual Preferred Units.”

If any one of these events were to occur, our financial condition, results of operations, cash flow, per share/unit trading price of ESRT's Class A common stock and our traded OP units and our ability to satisfy our principal, interest and preferred unit distribution obligations and to make distributions to our securityholders could be adversely affected. In addition, in connection with our debt agreements we may enter into lockbox and cash management agreements pursuant to which substantially all of the income generated by our properties will be deposited directly into lockbox accounts and then swept into cash management accounts for the benefit of our various lenders and from which cash will be distributed to us only after funding of improvement, leasing and maintenance reserves and the payment of principal and interest on our debt, insurance, taxes, operating expenses and extraordinary capital expenditures and leasing expenses. As a result, we may be forced to borrow additional funds in order to make distributions to our securityholders (including, potentially, to make distributions necessary to allow ESRT satisfy the requirements applicable to REITs). See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources."

Mortgage debt obligations expose us to the possibility of foreclosure, which could result in the loss of our investment in a property or group of properties subject to mortgage debt.

Incurring mortgage and other secured debt obligations increases our risk of property losses because defaults on indebtedness secured by properties may result in foreclosure actions initiated by lenders and ultimately our loss of the property securing any loans for which we are in default. Any foreclosure on a mortgaged property or group of properties could adversely affect the overall value of our portfolio of properties. For tax purposes, a foreclosure of any of our properties that is subject to a nonrecourse mortgage loan would be treated as a sale of the property for a purchase price equal to the outstanding balance of the debt secured by the mortgage. If the outstanding balance of the debt secured by the mortgage exceeds our tax basis in the property, we would recognize taxable income on foreclosure, but would not receive any cash proceeds, which could hinder our ability to make distributions to ESRT in order to allow it to meet the distribution requirements applicable to REITs under the Code. Foreclosures could also trigger our tax indemnification obligations under the terms of our agreements with certain continuing investors with respect to sales of certain properties, and obligate us to make certain levels of indebtedness available for them to guarantee which.

High mortgage rates and/or unavailability of mortgage debt may make it difficult for us to finance or refinance properties, which could reduce the number of properties we can acquire, our net income and the amount of cash distributions we can make.

If mortgage debt is unavailable at reasonable rates, we may not be able to finance the purchase of properties. If we place mortgage debt on properties, we may be unable to refinance the properties when the loans become due, or to refinance on favorable terms. If interest rates are higher when we refinance our properties, our income could be reduced. If any of these events occur, our cash flow could be reduced. This, in turn, could reduce cash available for distribution to our securityholders and may hinder our ability to raise more capital by issuing more stock or by borrowing more money. In addition, to the extent we are unable to refinance the properties when the loans become due, we will have fewer debt guarantee opportunities available to offer under our tax protection agreement. If we are unable to offer certain guarantee opportunities to the protected parties under the tax protection agreement, or otherwise are unable to allocate sufficient liabilities of our company to those parties, it could trigger an indemnification obligation of our company under the tax protection agreement.

Some of our financing arrangements involve balloon payment obligations, which may adversely affect our ability to make distributions.

As of December 31, 2015, we had total debt outstanding of approximately $1.6 billion. As of December 31, 2015, we had no debt maturing in 2016 and approximately $355.8 million of debt maturing in 2017. As of December 31, 2015, we had 13 mortgage loans outstanding secured by 11 of our properties. As of December 31, 2015, these loans had an aggregate estimated principal balance at maturity of approximately $735.1 million with maturity dates ranging from 2017 through 2024. See Note 6 to our consolidated financial statements for required payments of our indebtedness. Our financing arrangements require us to make a lump-sum or "balloon" payment at maturity. Our ability to make a balloon payment at maturity is uncertain and may depend upon our ability to obtain additional financing or our ability to sell the property. At the time the balloon payment is due, we may or may not be able to refinance the existing financing on terms as favorable as the original loan or sell the property at a price sufficient to make the balloon payment. The effect of a refinancing or sale could affect the rate of return to securityholders and the projected time of disposition of our assets. In addition, payments of principal and

interest made to service our debts may leave us with insufficient cash to make distributions necessary to allow ESRT to meet the distribution requirements applicable to REITs under the Code.

Our degree of leverage and the lack of a limitation on the amount of indebtedness we may incur could materially and adversely affect us.

Neither our nor ESRT's organizational documents contain any limitation on the amount of indebtedness we may incur. We consider factors other than debt-to-EBITDA in making decisions regarding the incurrence of indebtedness, such as the purchase price of properties to be acquired with debt financing, the estimated market value of our properties upon refinancing and the ability of particular properties and our business as a whole to generate cash flow to cover expected debt service.

Our degree of leverage could affect our ability to obtain additional financing for working capital, capital expenditures, acquisitions, development or other general corporate purposes. Our degree of leverage could also make us more vulnerable to a downturn in business or the economy generally. If we become more leveraged in the future, the resulting increase in debt service requirements could cause us to default on our obligations, which could materially and adversely affect us.

Our tax protection agreement could limit our ability either to sell certain properties or to engage in a strategic transaction, or to reduce our level of indebtedness, which could materially and adversely affect us.

In connection with the formation transactions, we and ESRT entered into a tax protection agreement with Anthony E. Malkin and Peter L. Malkin pursuant to which we have agreed to indemnify the Malkin Group and one additional third party investor in Metro Center (who was one of the original landowners and was involved in the development of the property) against certain tax liabilities if those tax liabilities result from (i) our sale, transfer, conveyance, or other taxable disposition of four specified properties (First Stamford Place, Metro Center, 10 Bank Street and 1542 Third Avenue) acquired by us in 2013 for a period of 12 years with respect to First Stamford Place and for the later of (x) October 2021 or (y) the death of both Peter L. Malkin and Isabel W. Malkin who are 82 and 79 years old, respectively, for the three other properties, (ii) our failing to maintain until maturity the indebtedness secured by those properties or failing to use commercially reasonable efforts to refinance such indebtedness upon maturity in an amount equal to the principal balance of such indebtedness, or, if we are unable to refinance such indebtedness at its current principal amount, at the highest principal amount possible, or (iii) our failing to make available to any of these continuing investors the opportunity to guarantee, or otherwise bear the risk of loss, for U.S. federal income tax purposes, of their allocable share of $160 million of aggregate indebtedness meeting certain requirements, until such continuing investor owns less than the aggregate number of operating partnership units and shares of ESRT common stock equal to 50% of the aggregate number of such units and shares such continuing investor received in the formation transactions. If we were to trigger our tax indemnification obligations under these agreements, we would be required to pay damages for the resulting tax consequences to the Malkin Group, and we have acknowledged that a calculation of damages will not be based on the time value of money or the time remaining within the restricted period. Moreover, these obligations may restrict our ability to engage in a strategic transaction. In addition, these obligations may require us to maintain more or different indebtedness than we would otherwise require for our business.

The continuing threat of a terrorist event may materially and adversely affect our properties, their value and our ability to generate cash flow.

There may be a decrease in demand for space in Manhattan and the greater New York metropolitan area because it is considered at risk for a future terrorist event, and this decrease may reduce our revenues from property rentals. In the aftermath of a terrorist event, tenants in Manhattan and the greater New York metropolitan area may choose to relocate their businesses to less populated, lower-profile areas of the United States that are not as likely to be targets of future terrorist activity. This in turn could trigger a decrease in the demand for space in Manhattan and the greater New York metropolitan area, which could increase vacancies in our properties and force us to lease our properties on less favorable terms. Further, certain of our properties, including the Empire State Building, may be considered to be susceptible to increased risks of a future terrorist event due to the high-profile nature of the property. In addition, a terrorist event could cause insurance premiums at certain of our properties to increase significantly. As a result, the value of our properties and the level of our revenues could materially decline.

Potential losses, such as those from adverse weather conditions, natural disasters, terrorist events and title claims, may not be fully covered by our insurance policies, and such losses could materially and adversely affect us.

Our business operations are susceptible to, and could be significantly affected by, adverse weather conditions, terrorist events and natural disasters that could cause significant damage to the properties in our portfolio. Our insurance may not be adequate to cover business interruption or losses resulting from such events. In addition, our insurance policies include substantial self-insurance portions and significant deductibles and co-payments for such events, and hurricanes in the United States have affected the availability and price of such insurance. As a result, we may incur significant costs in the event of adverse weather conditions, terrorist events and natural disasters. We may discontinue certain insurance coverage on some or all of our properties in the future if the cost of premiums for any of these policies in our judgment exceeds the value of the coverage discounted for the risk of loss.

deductible. ESRT Captive Insurance reinsures 100% of their 15% coinsurance for non-NBCR exposures. The 15% coinsurance on NBCR exposures is retained by ESRT Captive Insurance.

TRIA was not in effect for the period from January 1, 2015 through January 11, 2015. During this brief period of time, ESRT carried a reduced terrorism insurance limit, which we believed was commercially acceptable under the circumstances.

Furthermore, we do not carry insurance for certain losses, including, but not limited to, losses caused by war. In addition, while our title insurance policies insure for the current aggregate market value of our portfolio, we do not intend to increase our title insurance policies as the market value of our portfolio increases. As a result, we may not have sufficient coverage against all losses that we may experience, including from adverse title claims.

If we experience a loss that is uninsured or which exceeds our policy limits, we could incur significant costs and lose the capital invested in the damaged properties as well as the anticipated future cash flows from those properties. In addition, if the damaged properties are subject to recourse indebtedness, we would continue to be liable for the indebtedness, even if these properties were irreparably damaged.

In addition, certain of our properties could not be rebuilt to their existing height or size at their existing location under current land-use laws and policies. In the event that we experience a substantial or comprehensive loss of one of our properties, we may not be able to rebuild such property to its existing specifications and otherwise may have to upgrade such property to meet current code requirements.

Our debt instruments, consisting of mortgage loans secured by our properties (which are generally non-recourse to us), ground leases, our unsecured term loan and our unsecured revolving credit facility, contain customary covenants requiring us to maintain insurance, including terrorism insurance. While we do not believe it will be likely, there can be no assurance that the lenders or ground lessors under these instruments will not take the position that a total or partial exclusion from “all-risk” insurance coverage for losses due to terrorist acts is a breach of these debt and ground lease instruments that allows the lenders or ground lessors to declare an event of default and accelerate repayment of debt or recapture of ground lease positions for those properties in our portfolio which are not insured against terrorist events. In addition, if lenders insist on full coverage for these risks and prevail in asserting that we are required to maintain such coverage, it could result in substantially higher insurance premiums.

Certain mortgages on our properties 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. While the ratings of our insurers currently satisfy the rating requirements in some of our loan agreements, in the future, we may be unable to obtain insurance with insurers which satisfy the rating requirements which could give rise to an event of default under such loan agreements. 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 which are difficult to obtain or which result in a commercially unreasonable premium.

We may become subject to liability relating to environmental and health and safety matters, which could have a material and adverse effect on us.

Under various federal, state and/or local laws, ordinances and regulations, as a current or former owner or operator of real property, we may be liable for costs and damages resulting from the presence or release of hazardous substances, waste, or petroleum products at, on, in, under or from such property, including costs for investigation or remediation, natural resource damages, or third party liability for personal injury or property damage. These laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the presence or release of such materials, and the liability may be joint and several. Some of our properties have been or may be impacted by contamination arising from current or prior uses of the property or adjacent properties for commercial, industrial or other purposes. Such contamination may arise from spills of petroleum or hazardous substances or releases from tanks used to store such materials. We also may be liable for the costs of remediating contamination at off-site disposal or treatment facilities when we arrange for disposal or treatment of hazardous substances at such facilities, without regard to whether we comply with environmental laws in doing so. The presence of contamination or the failure to remediate contamination on our properties may adversely affect our ability to attract and/or retain tenants and our ability to develop or sell or borrow against those properties. In addition to potential liability for cleanup costs, private plaintiffs may bring claims for personal injury, property damage or for similar reasons. Environmental laws also may create liens on contaminated sites in favor of the government for damages and costs it incurs to address such contamination. Moreover, if contamination is discovered on our properties, environmental laws may impose restrictions on the manner in which that property may be used or how businesses may be operated on that property. For example, our property at 69-97 Main Street is subject to an Environmental Land Use Restriction that imposes certain restrictions on the use, occupancy and activities of the affected land beneath the property. This restriction may prevent us from conducting certain redevelopment activities at the property, which may adversely affect its resale value and may adversely affect our ability to finance or refinance this property. See “Item 1. Business - Environmental Matters.”

future contain, may contain, or may have contained, asbestos-containing material, or ACM. Environmental and health and safety laws require that ACM be properly managed and maintained and may impose fines or penalties on owners, operators or employers for non-compliance with those requirements. These requirements include special precautions, such as removal, abatement or air monitoring, if ACM would be disturbed during maintenance, redevelopment or demolition of a building, potentially resulting in substantial costs. In addition, we may be subject to liability for personal injury or property damage sustained as a result of releases of ACM into the environment.

In addition, our properties may contain or develop harmful mold or suffer from other indoor air quality issues, which could lead to liability for adverse health effects or property damage or costs for remediation. When excessive moisture accumulates in buildings or on building materials, mold growth may occur, particularly if the moisture problem remains undiscovered or is not addressed over a period of time. Some molds may produce airborne toxins or irritants. Indoor air quality issues can also stem from inadequate ventilation, chemical contamination from indoor or outdoor sources, and other biological contaminants such as pollen, viruses and bacteria. Indoor exposure to airborne toxins or irritants above certain levels can be alleged to cause a variety of adverse health effects and symptoms, including allergic or other reactions. As a result, the presence of significant mold or other airborne contaminants at any of our properties could require us to undertake a costly remediation program to contain or remove the mold or other airborne contaminants from the affected property or increase indoor ventilation. In addition, the presence of significant mold or other airborne contaminants could expose us to liability from our tenants, employees of our tenants or others if property damage or personal injury occurs.

We cannot assure you that costs or liabilities incurred as a result of environmental issues will not affect our ability to make distributions to our securityholders or that such costs, liabilities, or other remedial measures will not have a material adverse effect on our financial condition and results of operations.

Failure to hedge interest rates effectively could have a material and adverse effect on us.

We may seek to manage our exposure to interest rate volatility by using interest rate hedging arrangements that involve risk, such as the risk that counterparties may fail to honor their obligations under these arrangements, and that these arrangements may not be effective in reducing our exposure to interest rate changes. Moreover, there can be no assurance that our hedging arrangements will qualify for hedge accounting or that our hedging activities will have the desired beneficial impact on our results of operations. Should we desire to terminate a hedging agreement, there could be significant costs and cash requirements involved to fulfill our initial obligation under the hedging agreement. Failure to hedge effectively against interest rate changes may adversely affect our results of operations.

When a hedging agreement is required under the terms of a mortgage loan, it is often a condition that the hedge counterparty maintains a specified credit rating. When there is volatility in the financial markets, there is an increased risk that hedge counterparties could have their credit rating downgraded to a level that would not be acceptable under the loan provisions. If we were unable to renegotiate the credit rating condition with the lender or find an alternative counterparty with acceptable credit rating, we could be in default under the loan and the lender could seize that property through foreclosure.

We may incur significant costs complying with the ADA and similar laws, which could adversely affect our financial condition, results of operations, cash flow and per share/unit trading price of ESRT's Class A common stock and our traded OP units.

Under the Americans with Disabilities Act of 1990, or the ADA, all public accommodations must meet federal requirements related to access and use by disabled persons. We have not conducted a recent audit or investigation of all of our properties to determine our compliance with the ADA. If one or more of the properties in our portfolio is not in compliance with the ADA, we would be required to incur additional costs to bring the property into compliance. Additional federal, state and local laws also may require modifications to our properties, or restrict our ability to renovate our properties. We cannot predict the ultimate cost of compliance with the ADA or other legislation. If we incur substantial costs to comply with the ADA and any other legislation, our financial condition, results of operations, cash flow, per share/unit trading price of ESRT's Class A common stock and our traded OP units and our ability to satisfy our principal and interest obligations and to make distributions to our securityholders could be adversely affected.

Our property taxes could increase due to property tax rate changes or reassessment, which could impact our cash flows.

Even if ESRT qualifies as a REIT for U.S. federal income tax purposes, we will be required to pay state and local taxes on our properties. The real property taxes on our properties may increase as property tax rates change or as our properties are assessed or reassessed by taxing authorities. Therefore, the amount of property taxes we pay in the future may increase substantially from what we have paid in the past. If the property taxes we pay increase, our financial condition, results of operations, cash flows, per share/unit trading price of ESRT's Class A common stock and our traded OP units and our ability to satisfy our principal and interest obligations and to make distributions to our securityholders could be adversely affected.

We or ESRT may become subject to litigation, which could have a material and adverse effect on our financial condition, results of operations, cash flow and per share/unit trading price of ESRT's Class A common stock and our traded OP units.

In the future we or ESRT may become subject to litigation, including claims relating to our operations, offerings, and otherwise in the ordinary course of business. Some of these claims may result in significant defense costs and potentially significant judgments against us, some of which are not, or cannot be, insured against. We generally intend to defend ourselves vigorously; however, we cannot be certain of the ultimate outcomes of any claims that may arise in the future. Resolution of these types of matters against us or ESRT may result in our having to pay significant fines, judgments, or settlements, which, if uninsured, or if the fines, judgments, and settlements exceed insured levels, could adversely impact our earnings and cash flows, thereby having an adverse effect on our financial condition, results of operations, cash flow and per share/unit trading price of ESRT's Class A common stock and our traded OP units. Certain litigation or the resolution of certain litigation may affect the availability or cost of some of our insurance coverage, which could adversely impact our results of operations and cash flows, expose us to increased risks that would be uninsured, and/or adversely impact ESRT's ability to attract officers and directors. There is currently litigation pending, and the potential for additional litigation, associated with the consolidation. We may incur costs from these litigations. Please see Footnote 10 “Commitments and Contingencies” to the financial statements on of this Annual Report in Form 10-K for a description of such legal proceedings.

We face risks relating to cybersecurity attacks that could cause loss of confidential information and other business disruptions.

We rely extensively on computer systems to process transactions and manage our business, and our business is at risk from and may be impacted by cybersecurity attacks. These could include attempts to gain unauthorized access to our data and computer systems. Attacks can be both individual and/or highly organized attempts organized by very sophisticated hacking organizations. We employ a number of measures to prevent, detect and mitigate these threats, which include password protection, frequent password change events, firewall detection systems, frequent backups, a redundant data system for core applications and annual penetration testing; however, there is no guarantee such efforts will be successful in preventing a cybersecurity attack. A cybersecurity attack could compromise the confidential information of our employees, tenants and vendors. A successful attack could disrupt and affect the business operations.

Risks Related to Our Organization and Structure

Holders of ESRT Class B common stock have a significant vote in matters submitted to a vote of ESRT Securityholders.

As part of our formation, original investors were offered the opportunity to contribute their interests to us in exchange for ESRT Class A common stock, operating partnership units, a combination of one share of ESRT Class B common stock for each 50 operating partnership units to which an investor was entitled, resulting in one share of ESRT Class B common stock and 49 operating partnership units, or a combination of any of the above. Each outstanding share of ESRT Class B common stock entitles the holder thereof to 50 votes on all matters on which ESRT Class A common securityholders are entitled to vote, including the election of directors. Holders of ESRT Class B common stock are entitled to share equally, on a per share basis, in all distributions payable with respect to shares of ESRT Class A common stock. Holders of ESRT Class B common stock may have interests that differ from those holders of ESRT Class A common stock and our securityholders, including by reason of their interest in us, and may accordingly vote as a stockholder in ways that may not be consistent with the interests of holders of ESRT Class A common stock and our securityholders. This significant voting influence over certain matters may have the effect of delaying, preventing or deterring a change of control of ESRT, or could deprive holders of ESRT Class A common stock or our securityholders of an opportunity to receive a premium for their Class A common stock or units, as applicable, as part of a sale of ESRT. ESRT Class B common stock has been issued only in connection with the formation transactions as described above, and any such share is automatically converted to a share of ESRT Class A common stock (having a single vote) upon its holder conveying the related 49 operating partnership units to any person other than a family member, affiliate or controlled entity of such person.

The departure of any of ESRT key personnel could materially and adversely affect us.

Our success depends on the efforts of ESRT key personnel, particularly Anthony E. Malkin, ESRT's and Chief Executive Officer. Among the reasons Anthony E. Malkin is important to our success is that he has a national industry reputation that benefits us in many ways. He has led the acquisition, operating and repositioning of our assets for the last two decades. If we lost his services, our external relationships and internal leadership resources would be materially diminished.

Other members of ESRT senior management team also have strong industry reputations and experience, which aid us in attracting, identifying and exploiting opportunities. The loss of the services of one or more members of ESRT's senior management team, particularly Anthony E. Malkin, could have a material and adverse impact on us.

Tax consequences to holders of operating partnership units upon a sale or refinancing of our properties may cause the interests of certain members of ESRT senior management team to differ from your own.

As a result of the unrealized built-in gain attributable to a property at the time of contribution, some holders of operating partnership units, including Anthony E. Malkin and Peter L. Malkin, may suffer different and more adverse tax consequences than other holders of operating partnership units upon the sale or refinancing of the properties owned by us, including disproportionately greater allocations of items of taxable income and gain upon a realization event. As those holders will not receive a correspondingly greater distribution of cash proceeds, they may have different objectives regarding the appropriate pricing, timing and other material terms of any sale or refinancing of certain properties, or whether to sell or refinance such properties at all. As a result, the effect of certain transactions on Anthony E. Malkin and Peter L. Malkin may influence their decisions affecting these properties and may cause such members of ESRT senior management team to attempt to delay, defer or prevent a transaction that might otherwise be in the best interests of our other securityholders. In connection with the formation transactions, we and ESRT entered into a tax protection agreement with Anthony E. Malkin and Peter L. Malkin pursuant to which we have agreed to indemnify the Malkin Group and one additional third party investor in Metro Center (who was one of the original landowners and was involved in the development of the property) against certain tax liabilities if those tax liabilities result from (i) our sale, transfer, conveyance, or other taxable disposition of four specified properties (First Stamford Place, Metro Center, 10 Bank Street and 1542 Third Avenue) acquired by us in the consolidation for a period of 12 years from the consolidation in 2013 with respect to First Stamford Place and for the later of (x) eight years from the consolidation in 2013 or (y) the death of both Peter L. Malkin and Isabel W. Malkin who are 82 and 79 years old, respectively, for the three other properties, (ii) our failing to maintain until maturity the indebtedness secured by those properties or failing to use commercially reasonable efforts to refinance such indebtedness upon maturity in an amount equal to the principal balance of such indebtedness, or, if we are unable to refinance such indebtedness at its current principal amount, at the highest principal amount possible, or (iii) our failing to make available to any of these continuing investors the opportunity to guarantee, or otherwise bear the risk of loss, for U.S. federal income tax purposes, of their allocable share of $160 million of aggregate indebtedness meeting certain requirements, until such continuing investor owns less than the aggregate number of operating partnership units and shares of ESRT common stock equal to 50% of the aggregate number of such units and shares such continuing investor received in the formation transactions. As a result of entering into the tax protection agreement, Anthony E. Malkin and Peter L. Malkin may have an incentive to cause us to enter into transactions from which they may personally benefit.

ESRT's Chairman and Chief Executive Officer has outside business interests that take his time and attention away from us, which could materially and adversely affect us.

Anthony E. Malkin, ESRT's Chairman and Chief Executive Officer, has agreed to devote a majority of his business time and attention to our business and, under his employment agreement, he may also devote time to the excluded properties, the excluded businesses and certain family investments to the extent that such activities do not materially interfere with the performance of his duties to us. He owns interests in the excluded properties and excluded businesses that were not contributed to us in the formation transactions, some of which are managed by our company and certain non-real estate family investments. In some cases, Anthony E. Malkin or his affiliates have certain management and fiduciary obligations that may conflict with such person’s responsibilities as an officer or director of ESRT and may adversely affect our operations. In addition, under his employment agreement, Anthony E. Malkin has agreed not to engage in certain business activities in competition with us (both during, and for a period of time following, his employment with us). We may choose not to enforce, or to enforce less vigorously, our rights under this agreement because of our desire to maintain our ongoing relationship with our Chairman and Chief Executive Officer given his significant knowledge of our business, relationships with our customers and significant equity ownership in us, and this could have a material adverse effect on our business.

ESRT's rights and the rights of ESRT's Securityholders to take action against ESRT's directors and officers are limited, which could limit your recourse in the event of actions not in your best interest.

ESRT's charter limits the liability of ESRT's present and former directors and officers to ESRT and its securityholders for money damages to the maximum extent permitted under Maryland law. Under current Maryland law, ESRT's present and former directors and officers will not have any liability to it or its securityholders for money damages other than liability resulting from (1) actual receipt of an improper benefit or profit in money, property or services or (2) active and deliberate dishonesty by the director or officer that was established by a final judgment and is material to the cause of action. As a result, ESRT and its securityholders may have limited rights against ESRT's present and former directors and officers, as well as persons who served as members, managers, shareholders, directors, partners, officers, controlling persons certain agents of our predecessor, which could limit your recourse in the event of actions not in your best interest.

Conflicts of interest exist or could arise in the future between the interests of ESRT Securityholders and the interests of holders of operating partnership units, which may impede business decisions that could benefit our securityholders.

Conflicts of interest exist or could arise in the future as a result of the relationships between us and our affiliates, on the one hand, and ESRT or any stockholder thereof, on the other. ESRT directors and officers have duties to ESRT under applicable Maryland law in connection with their management of ESRT. At the same time, ESRT, as the general partner of our company, has fiduciary duties and obligations to our company and our limited partners under Delaware law and our partnership agreement in connection with the management of us. ESRT’s fiduciary duties and obligations as general partner to our company and our partners may come into conflict with the duties of ESRT’s directors and officers to ESRT. Pursuant to our partnership agreement, our limited partners have agreed that in the event of a conflict in the duties owed by ESRT's directors and officers to ESRT and ESRT's securityholders and the fiduciary duties owed by ESRT, in its capacity as general partner of us, to such limited partners, ESRT will fulfill its fiduciary duties to such limited partners by acting in the best interests of ESRT's securityholders.

Additionally, the partnership agreement provides that ESRT and its directors and officers will not be liable or accountable to us for losses sustained, liabilities incurred or benefits not derived if ESRT, or such director or officer acted in good faith. The partnership agreement also provides that ESRT will not be liable to us or any partner for monetary damages for losses sustained, liabilities incurred or benefits not derived by us or any limited partner, except for liability for ESRT’s intentional harm or gross negligence. Moreover, the partnership agreement provides that we are required to indemnify our directors and officers, ESRT and its directors and officers and authorizes us to indemnify present and former members, managers, shareholders, directors, limited partners, general partners, officers or controlling persons of our predecessor and authorizes us to indemnify members, partners, employees and agents of us or our predecessor, in each case for actions taken by them in those capacities from and against any and all claims that relate to the operations of our company, except (1) if the act or omission of the person was material to the matter giving rise to the action and either was committed in bad faith or was the result of active and deliberate dishonesty, (2) for any transaction for which the indemnified party received an improper personal benefit, in money, property or services or otherwise, in violation or breach of any provision of the partnership agreement or (3) in the case of a criminal proceeding, if the indemnified person had reasonable cause to believe that the act or omission was unlawful. No reported decision of a Delaware appellate court has interpreted provisions similar to the provisions of our partnership agreement that modify and reduce ESRT’s fiduciary duties or obligations as the general partner or reduce or eliminate ESRT’s liability for money damages to us and our partners, and ESRT has not obtained an opinion of counsel as to the enforceability of the provisions set forth in the partnership agreement that purport to modify or reduce the fiduciary duties that would be in effect were it not for the partnership agreement.

ESRT could increase or decrease the number of authorized shares of ESRT stock, classify and reclassify unissued ESRT stock and issue ESRT stock without ESRT stockholder approval, which could prevent a change in control of ESRT and negatively affect the market value of ESRT's shares.

ESRT’s board of directors, without stockholder approval, has the power under ESRT’s charter to amend its charter from time to time to increase or decrease the aggregate number of ESRT shares of stock or the number of ESRT shares of stock of any class or series that ESRT is authorized to issue, to authorize ESRT to issue authorized but unissued shares of ESRT common stock or preferred stock and to classify or reclassify any unissued shares of ESRT common stock or preferred stock into one or more classes or series of stock and set the terms of such newly classified or reclassified shares. As a result, ESRT may issue series or classes of ESRT common stock or preferred stock with preferences, distributions, powers and rights, voting or otherwise, that are senior to, or otherwise conflict with, the rights of holders of ESRT common stock. Any such issuance could dilute existing ESRT securityholders’ interests. Although ESRT’s board of directors has no such intention at the present time, it could establish a class or series of ESRT preferred stock that could, depending on the terms of such series, delay, defer

or prevent a transaction or a change of control that might involve a premium price for ESRT's common stock or that our ESRT securityholders otherwise believe to be in their best interest.

We may issue additional operating partnership units without the consent of our securityholders, which could have a dilutive effect on our securityholders and ESRT’s Securityholders.

We may issue additional operating partnership units to third parties without the consent of our securityholders, which would reduce ESRT’s ownership percentage in us and would have a dilutive effect on the interests of our existing securityholders and on the amount of distributions made to ESRT, our securityholders and to us and, therefore, the amount of distributions ESRT can make to its securityholders. Any such issuances, or the perception of such issuances, could materially and adversely affect the market price of ESRT's Class A common stock or our traded OP units.

Certain provisions in our partnership agreement of may delay or prevent unsolicited acquisitions of us.

Provisions in our partnership agreement may delay or make more difficult unsolicited acquisitions of us or changes of our control. These provisions could discourage third parties from making proposals involving an unsolicited acquisition of us or change of our control, although some of our securityholders might consider such proposals, if made, desirable. These provisions include, among others:


•	redemption rights of qualifying parties;


•	transfer restrictions on operating partnership units;


•	ESRT's ability, as general partner, in some cases, to amend the partnership agreement and to cause us to issue units with terms that could delay, defer or prevent a merger or other change of control of us or ESRT without the consent of the limited partners;


•	the right of the limited partners to consent to transfers of the general partnership interest and mergers or other transactions involving us under specified circumstances; and


•	a redemption premium payable to the holders of our operating partnership’s preferred units if our operating partnership decides, at its option, to redeem preferred units for cash upon the occurrence of certain fundamental transactions, such as a change of control.

ESRT's charter, bylaws, our partnership agreement and Maryland law also contain other provisions that may delay, defer or prevent a transaction or a change of control that might involve a premium price for our units or that of our securityholders or ESRT's common stock or that its securityholders otherwise believe to be in their best interest.

ESRT's charter contains stock ownership limits, which may delay or prevent a change of control.

In order for ESRT to qualify as a REIT no more than 50% in value of our outstanding capital stock may be owned, directly or indirectly, by five or fewer individuals during the last half of any calendar year, and at least 100 persons must beneficially own its stock during at least 335 days of a taxable year of 12 months, or during a proportionate portion of a shorter taxable year. “Individuals” for this purpose include natural persons, private foundations, some employee benefit plans and trusts and some charitable trusts. To assist ESRT in complying with these limitations, among other purposes, ESRT’s charter generally prohibits any person from directly or indirectly owning more than 9.8% in value or number of shares, whichever is more restrictive, of the outstanding shares of ESRT’s capital stock or more than 9.8% in value or number of shares, whichever is more restrictive, of the outstanding shares of ESRT’s common stock. These ownership limitations could have the effect of discouraging a takeover or other transaction in which holders of ESRT’s common stock might receive a premium for their shares over the then prevailing market price or which holders might believe to be otherwise in their best interests. ESRT has entered into waivers of the 9.8% ownership limit with two institutional investors to permit each of these institutional investors to own up to 15% of the outstanding shares of ESRT Class A common stock.

ESRT’s charter’s constructive ownership rules are complex and may cause the outstanding shares owned by a group of related individuals or entities to be deemed to be constructively owned by one individual or entity. As a result, the acquisition of less than these percentages of the outstanding shares by an individual or entity could cause that individual or entity to own constructively in excess of these percentages of the outstanding shares and thus violate the share ownership limits. ESRT’s charter also provides that any attempt to own or transfer shares of its common stock or preferred stock (if and when issued) in excess of the stock ownership limits without the consent of ESRT’s board of directors or in a manner that would cause ESRT to be “closely held” under Section 856(h) of the Code (without regard to whether the shares are held during the last half of a taxable year) will result in the shares being deemed to be transferred to a trustee for a charitable trust or, if the transfer to the charitable trust is not automatically effective to prevent a violation of the share ownership limits or the restrictions on ownership and transfer of ESRT shares, any such transfer of ESRT’s shares will be null and void.

The concentration of ESRT's voting power may adversely affect the ability of new investors to influence our policies.

As of December 31, 2015, Anthony E. Malkin, ESRT’s Chairman and Chief Executive Officer, together with the Malkin Group, has the right to vote 42,101,592 shares of ESRT’s common stock, which represents approximately 24.1% of the voting power of ESRT’s outstanding common stock. Consequently, Mr. Malkin has the ability to influence the outcome of matters presented to ESRT securityholders, including the election of ESRT’s board of directors and approval of significant corporate transactions, including business combinations, consolidations and mergers and the determination of ESRT’s day-to-day corporate and management policies. Therefore, Mr. Malkin has substantial influence over ESRT and us and could exercise influence in a manner that is not in the best interests of ESRT’s other securityholders or our securityholders. This concentration of voting power might also have the effect of delaying or preventing a change of control that ESRT’s securityholders or our securityholders may view as beneficial.

Our sole general partner, ESRT, acting through its board of directors may change our strategies, policies or procedures without stockholder consent, which may subject us to different and more significant risks in the future.

Our investment, financing, leverage and distribution policies and our policies with respect to all other activities, including growth, debt, capitalization and operations, will be determined by our sole general partner, ESRT, acting through its board of directors. These policies may be amended or revised at any time and from time to time at the discretion of ESRT without notice to or a vote of our securityholders. This could result in us conducting operational matters, making investments or pursuing different business or growth strategies. Under these circumstances, ESRT may expose us to different and more significant risks in the future, which could have a material adverse effect on our business and growth. In addition, ESRT may change our policies with respect to conflicts of interest provided that such changes are consistent with applicable legal requirements. A change in these policies could have an adverse effect on our financial condition, results of operations, cash flow, per unit trading price of our traded OP units and ability to satisfy our principal and interest obligations and to make distributions to our securityholders.

Our sole general partner, ESRT, acting through its board of directors has approved very broad investment guidelines for our company and will not review or approve each investment decision made by ESRT's senior management team.

ESRT’s senior management team is authorized to follow broad investment guidelines and, therefore, has great latitude in determining the types of assets that are proper investments for us, as well as the individual investment decisions. ESRT’s senior management team may make investments with lower rates of return than those anticipated under current market conditions and/or may make investments with greater risks to achieve those anticipated returns. Our sole general partner, ESRT, acting through its board of directors will not review or approve each proposed investment by ESRT’s senior management team.

Risks Related to ESRT Common Stock and our Traded OP Units

Our cash available for distribution may not be sufficient to make distributions at expected levels.

We intend to make distributions to our securityholders. All dividends and distributions will be made at the discretion of our sole general partner, ESRT, acting through its board of directors, and will depend on our earnings, financial condition, maintenance of ESRT’s REIT qualification and other factors as ESRT’s board of directors may deem relevant from time to time. If sufficient cash is not available for distribution from our operations, we may have to fund distributions from working capital or to borrow to provide funds for such distribution, or to reduce the amount of such distribution. We cannot assure you that our distributions will be made or sustained. Any distributions we pay in the future will depend upon our actual results of operations, economic conditions and other factors that could differ materially from our current expectations.

The market price of shares of ESRT's Class A common stock and our traded OP units could be adversely affected by our level of cash distributions.

The market value of the equity securities of a REIT is based primarily upon the market’s perception of the REIT’s growth potential and its current and potential future cash distributions, whether from operations, sales or refinancings, and is secondarily based upon the real estate market value of the underlying assets. For that reason, ESRT's Class A common stock and traded OP units may trade at prices that are higher or lower than our net asset value per share. To the extent we retain operating cash flow for investment purposes, working capital reserves or other purposes, these retained funds, while increasing the value of our underlying assets, may not correspondingly increase the market price of ESRT's Class A common stock and

traded OP units. Our failure to meet the market’s expectations with regard to future earnings and cash distributions likely would adversely affect the market price of ESRT's Class A common stock and our traded OP units.

Future issuances of debt securities or preferred units, which would rank senior to shares of ESRT common stock upon our liquidation, and future issuances of equity securities (including operating partnership units), which would dilute the holdings of ESRT's existing common securityholders and may be senior to shares of ESRT common stock for the purposes of making distributions, periodically or upon liquidation, may materially and adversely affect the market price of shares of ESRT Class A common stock and our traded OP units.

In the future, we or ESRT may issue debt or equity securities or make other borrowings. Upon liquidation, holders of our or ESRT’s debt securities, preferred units and other loans and preferred shares will receive a distribution of our available assets before holders of shares of ESRT’s common stock. We or ESRT are not required to offer any such additional debt or equity securities to existing ESRT securityholders or our securityholders, as applicable, on a preemptive basis. Therefore, additional shares of ESRT’s common stock issuances, directly or through convertible or exchangeable securities (including operating partnership units), warrants or options, will dilute the holdings of ESRT’s existing common securityholders and such issuances or the perception of such issuances may reduce the market price of shares of ESRT’s Class A common stock or our traded OP units. ESRT’s preferred units or shares, if issued, would likely have a preference on distribution payments, periodically or upon liquidation, which could limit ESRT’s ability to make distributions to holders of shares of ESRT’s common stock. Because our or ESRT’s decision to issue debt or equity securities or otherwise incur debt in the future will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our or ESRT's future capital raising efforts. Thus, holders of shares of ESRT’s common stock or our securityholders bear the risk that our or ESRT’s future issuances of debt or equity securities or ESRT's other borrowings will reduce the market price of shares of ESRT’s Class A common stock and our traded OP units and dilute their ownership in us or ESRT, as applicable.

Our balance sheet includes significant amounts of goodwill. The impairment of a significant portion of this goodwill could negatively affect our business, financial condition and results of operations.

Our balance sheet includes goodwill of approximately $491.5 million at December 31, 2015. These assets consist primarily of goodwill associated with our acquisition of the controlling interest in Empire State Building Company L.L.C. and 501 Seventh Avenue Associates L.L.C. We also expect to engage in additional acquisitions, which may result in our recognition of additional goodwill. Under accounting standards goodwill is not amortized. On an annual basis and whenever events or changes in circumstances indicate the carrying value or goodwill may be impaired, we are required to assess whether there have been impairments in the carrying value of goodwill. If the carrying value of the asset is determined to be impaired, then it is written down to fair value by a charge to operating earnings. An impairment of goodwill could have a material adverse effect on our business, financial condition and results of operations.

Tax Risks Related to Ownership of Our Units

If we are treated as a corporation for U.S. federal income tax purposes, we will be subject to entity-level U.S. federal income tax and ESRT will cease to qualify as a REIT.

We believe that we qualify as a partnership for U.S. federal income tax purposes. Assuming that we qualify as a partnership for U.S. federal income tax purposes, we are not subject to U.S. federal income tax on our income. Instead, each of our securityholders, including ESRT, is required to include in income its allocable share of our income. We are treated as publicly traded partnership under the Code, and accordingly we will be treated as a corporation for U.S. federal income tax purposes unless we meet certain requirements. In particular, in order to qualify as a partnership for U.S federal income tax purposes, at least 90% of our gross income must be derived from certain specified sources of qualifying income, which generally includes income treated as qualifying rental income for purposes of the REIT gross income tests and other income from passive sources. We believe that we satisfy this test. No assurance can be provided, however, that the IRS will not challenge our status as a partnership for U.S. federal income tax purposes, or that a court would not sustain such a challenge. If the IRS were successful in treating us as a corporation for U.S. federal income tax purposes, we would be subject to U.S. federal, state and local corporate income tax, which would significantly reduce the amount of cash available to satisfy obligations to make principal and interest payments on our debt and to make distribution to our securityholders, and the tax consequences of holding our operating partnership units could be adversely affected. In addition, ESRT would cease to qualify as a REIT.

You may be allocated more taxable income than the distributions you receive from us.

So long as we remain eligible to be taxed as a partnership for U.S. federal income tax purposes, we generally are not subject to U.S. federal income tax. Rather, each holder of our operating partnership units is required to take into account its allocable share of items of our income, gain, loss, deduction and credit for our taxable year ending within or with the taxable year of such holder in computing such holder's U.S. federal income tax liability, regardless of whether the holder has received any distributions from us. It is possible that the U.S. federal income tax liability of a holder of our operating partnership units with respect to its allocable share of our earnings in a particular taxable year could exceed the cash distributions we make to the holder for the year, thus requiring an out-of-pocket tax payment by the holder.

Your ability to deduct certain losses allocated from us may be subject to limitations.

Your ability to utilize any tax losses or deductions generated by us may be limited under the “at risk” limitation in Section 465 of the Code, the passive activity loss limitation in Section 469 of the Code, the basis limitation of Section 704(d) of the Code, and/or other provisions of the Code. These limitations may, among other things, prevent a holder from utilizing allocations of loss and deduction from us against income from other sources. Furthermore, your ability to utilize certain specific items of deduction may be limited under certain provisions of the Code. The application of these limitations depends on the exact nature of our current and future operations and the individual tax positions of such holders. Holders of operating partnership units should consult with their tax advisor regarding the potential application of these provisions.

Participants may recognize taxable gain resulting from a reduction in their allocable share of our liabilities.

We may elect to pay down our indebtedness or refinance such indebtedness with unsecured debt, which may reduce the amount of our liabilities allocable to a holder of operating partnership units. In addition, certain commitments pursuant to our tax protection agreement could result in less liabilities available to be allocated to holders of operating partnership units as a result of our obligation to offer to certain parties opportunities to guarantee certain indebtedness. Over time, property depreciation, capital improvements made to the properties and debt amortization and repayment, among other things, may reduce the share of our liabilities allocated to a holder of operating partnership units. A reduction in the share of our liabilities allocated to a holder of operating partnership units (such as from a pay down of mortgage debt over time) that exceeds the holder's U.S. federal income tax basis in its operating partnership units is treated as taxable gain from the sale or exchange of such units. Holders of our operating partnership units should consult their tax advisors with regard to their share of our liabilities.

Failure of ESRT to qualify as a REIT would have a material adverse effect on us.

We, in general, and the holders of our operating partnership units, in particular, must rely on ESRT, as our general partner, to manage our affairs and business. ESRT is subject to certain risks that may affect its financial and other conditions, including particularly adverse consequences if it fails to qualify as a REIT for U.S. federal income tax purposes. ESRT's qualification as a REIT involves the application of highly technical and complex Code provisions and Treasury Regulations promulgated thereunder for which there are limited judicial and administrative interpretations. Furthermore, ESRT's qualification as a REIT depends in part on the nature of our assets and income and the results of our operations. Moreover, new legislation, court decisions or administrative guidance, in each case possibly with retroactive effect, may make it more difficult or impossible for ESRT to qualify as a REIT. Thus, while we and ESRT intend to operate so that ESRT will qualify as a REIT, given the highly complex nature of the rules governing REITs, the ongoing importance of factual determinations, and the possibility of future changes in circumstances, no assurance can be given that ESRT will so qualify for any particular year. These considerations also might restrict the types of assets that we can acquire in the future.

If ESRT fails to qualify as a REIT it will face serious tax consequences which will directly and adversely impact us and may substantially reduce the funds available for payment of distributions to our securityholders, and it will be not be able to qualify as a REIT for four years following such failure. If ESRT fails to qualify as a REIT but is eligible for certain relief provisions, then it may retain its status as a REIT but may be required to pay a penalty tax, which could be substantial.

In order to enable ESRT to comply with the REIT requirements, we may be required to forego and/or liquidate otherwise attractive investments.

To qualify as a REIT, (and avoid certain taxes to which it would be subject notwithstanding its status as a REIT), ESRT must meet, on an ongoing basis, certain tests regarding the nature and diversification of its assets and its income. Because substantially all of ESRT's assets consists of our partnership units and substantially all of ESRT's income consists of income allocations with respect to such units, ESRT's ability to satisfy these tests will depend on the composition of our assets

and income. Similarly, in order to be treated as a partnership for U.S. federal income tax purposes, we must meet certain annual tests relating to the sources of our gross income. In order to meet these tests and to allow ESRT to meet these tests, we may be required to take or forgo taking actions that we would otherwise consider advantageous. For instance, we may be required to forego investments that we otherwise would make. Furthermore, we may be required to liquidate from our portfolio otherwise attractive investments. In addition, we may be required to make distributions to ESRT at disadvantageous times or when we do not have funds readily available for distribution. These actions could have the effect of reducing our income and amounts available for distribution to our securityholders. Thus, operating in a manner that allows ESRT to comply with the REIT requirements and causes us to continue to be treated as a partnership for U.S. federal income tax purposes may hinder our investment performance.

In order to allow ESRT to comply with the REIT distribution requirements, we may be required to borrow funds during unfavorable market conditions or may be subject to tax, which would reduce the cash available for distribution to our securityholders.

Our taxable income may exceed our net income as determined by GAAP because, for example, realized capital losses will be deducted in determining our GAAP net income, but may not be deductible in computing our taxable income. In addition, we may incur nondeductible capital expenditures or be required to make debt or amortization payments. As a result of the foregoing, we may generate less cash flow than taxable income in a particular year. As a result, we may be required to use cash reserves, incur debt or liquidate assets at rates or times that we regard as unfavorable in order to allow ESRT to satisfy the REIT 90% distribution requirement and to avoid U.S. federal income tax and the 4% nondeductible excise tax in that year.

Specific transactions or tax elections may cause you to recognize gain or otherwise affect your investment.

As a general matter, per the terms of our partnership agreement, ESRT is not required to take into account tax consequences to the other holders of operating partnership units in deciding whether to cause us to undertake specific transactions or make tax elections that could cause you to recognize gain. Consequently, we could enter into transactions that result in additional taxable income allocations to you at any time, and your share of our liabilities could be reduced at any time.

We cannot match transferors and transferees of Series 60, Series 250, or Series ES operating partnership units, and we have therefore adopted certain income tax accounting positions that may not conform with all aspects of applicable tax requirements. The IRS may challenge this treatment, which could adversely affect the tax consequences, liquidity and market price of such operating partnership units.

Because we cannot match transferors and transferees of Series 60, Series 250, or Series ES operating partnership units, we have adopted certain depreciation, amortization and other tax accounting positions that may not conform with all aspects of existing Treasury Regulations. A successful challenge to those positions could adversely affect the amount of tax benefit available or taxable income allocated to holders of such operating partnership units. It also could affect the timing of certain tax benefits or the amount of gain on the sale of such operating partnership units and could have a negative impact on the value of such operating partnership units or result in audits of and adjustments to the tax returns of holders of Series 60, Series 250, or Series ES operating partnership units.

In addition, our taxable income and losses are determined and apportioned among investors using conventions we regard as consistent with applicable law. As a result, if you transfer your operating partnership units, you may be allocated income, gain, loss and deduction realized by us after the date of transfer. Similarly, a transferee may be allocated income, gain, loss and deduction realized by us prior to the date of the transferee’s acquisition of operating partnership units and, in certain circumstances, even if such a transferee receives no distributions. A transferee may also bear the cost of withholding tax imposed with respect to income allocated to a transferor through a reduction in the cash distributed to the transferee.

If we are not able to lease the Empire State Building observatory to a TRS in a manner consistent with the ruling that ESRT has received from the IRS, or if we are not able to maintain our broadcast licenses in a manner consistent with the ruling ESRT has received from the IRS, we would be required to restructure our operations in a manner that could adversely affect the value of our operating partnership units.

Rents from real property are generally not qualifying income for purposes of the REIT gross income tests and the gross income test that we must satisfy in order to be treated as a partnership for U.S. federal income tax purposes if the rent is treated as “related party rent.” Related party rent generally includes (i) any rent paid by a corporation if the REIT (or any person who owns 10% or more of the stock of the REIT by value) directly or indirectly owns 10% or more of the stock of the corporation by vote or value and (ii) rent paid by a partnership if the REIT (or any person who owns 10% or more of the stock of the REIT by value) directly or indirectly owns an interest of 10% or more in the assets or net profits of the partnership. Under an exception to this rule, related party rent is treated as qualifying income for purposes of the REIT gross income tests if it is paid by a taxable REIT subsidiary, or a TRS, of the REIT and (i) at least 90% of the leased space in the relevant property is rented to persons other than either TRSs or other related parties of the REIT, and (ii) the amounts paid to the REIT as rent from real property are substantially comparable to the rents paid by unrelated tenants of the REIT for comparable space.

Income from admissions to the Empire State Building observatory, and certain other income generated by the observatory, would not likely be qualifying income for purposes of the REIT gross income tests. ESRT has jointly elected with ESRT Observatory TRS, L.L.C., or Observatory TRS, our wholly owned subsidiary and the current lessee and operator of the observatory, for Observatory TRS to be treated as a TRS of ESRT for U.S. federal income tax purposes. Observatory TRS leases the Empire State Building observatory from us pursuant to a lease that provides for fixed base rental payments and variable rental payments equal to certain percentages of Observatory TRS’s gross receipts from the operation of the observatory. Given the unique nature of the real estate comprising the observatory, ESRT does not believe that there is any space in the Empire State Building or in the same geographic area as the Empire State Building that would likely be considered sufficiently comparable to the observatory for the purpose of applying the exception to related party rent described above. ESRT has received from the IRS a private letter ruling that its allocable share of the rent that we receive from Observatory TRS pursuant to the lease described above is qualifying income for purposes of the REIT gross income tests.

In addition, we are party to various license agreements (i) granting certain third party broadcasters the right to use space on the tower on the top of the Empire State Building for certain broadcasting and other communication purposes and (ii) granting certain third party vendors the right to operate concession stands in the observatory. ESRT has received from the IRS a private letter ruling that its allocable share of the license fees that we receive under the license agreements described above are qualifying income for purposes of the REIT gross income tests.

ESRT is entitled to rely upon these private letter rulings only to the extent that it did not misstate or omit a material fact in the ruling request and that we and ESRT continue to operate in accordance with the material facts described in such request, and no assurance can be given that we or ESRT will always be able to do so. If ESRT were not able to treat its allocable share of the rent that the we receive from Observatory TRS as qualifying income for purposes of the REIT gross income tests, in order to qualify as a partnership for U.S. federal income tax purposes and in order to allow ESRT to continue to qualify as a REIT, we would be required to restructure the manner in which we operate the observatory, which would likely require us to cede operating control of the observatory by leasing the observatory to an affiliate or third party operator. If ESRT were not able to treat its allocable share of the license fees that we receive from the license agreements described above as qualifying income for purposes of the REIT gross income tests, in order to continue to be treated as a partnership for U.S. federal income tax purposes and in order to allow ESRT to continue to qualify as a REIT, we would be required to enter into the license agreements described above through a corporate subsidiary that elects to be treated as a TRS of ESRT, which would cause the license fees to be subject to U.S. federal income tax and accordingly reduce the amount of our cash flow available to be distributed to our securityholders. In either case, if we are not able to appropriately restructure our operations in a timely manner, ESRT would likely realize significant income that does not qualify for the REIT gross income tests, which could cause ESRT to fail to qualify as a REIT, and we could fail to be treated as a partnership for U.S. federal income tax purposes.

We may have inherited tax liabilities from the entities that have been merged into us or our subsidiaries in the formation transactions.

Pursuant to the formation transactions, Malkin Properties of Connecticut, Inc., a Connecticut corporation, or Malkin Properties CT, and Malkin Construction Corp., a Connecticut corporation, or Malkin Construction merged with and into a subsidiary of ESRT, with the subsidiary surviving, in a transaction that was intended to be treated as a reorganization under the Code, and which subsidiary was subsequently contributed to us. Each of Malkin Properties CT and Malkin Construction had previously elected to be treated as an S Corporation for U.S. federal income tax purposes under Section 1361 of the Code with

respect to periods preceding our formation transaction. If either of Malkin Properties CT or Malkin Construction had failed to qualify as an S corporation with respect to periods preceding our formation transaction, we could have assumed material U.S. federal income tax liabilities in connection with the formation transactions and/or may be subject to certain other adverse tax consequences. No rulings from the IRS were requested and no opinions of counsel were rendered regarding the U.S. federal income tax treatment of any of Malkin Properties CT or Malkin Construction with respect to periods preceding our formation transaction. Accordingly, no assurance can be given that Malkin Properties CT or Malkin Construction qualified as an S corporation for U.S. federal income tax purposes during such periods, or that these entities did not have any other tax liabilities. In addition, the supervisor merged with a subsidiary of us in the formation transactions, and as a result, we may have inherited any liabilities, including any tax liabilities, of the supervisor.

Your investment has various tax risks.

Although this section describes certain tax risks relevant to an investment in our securities, you should consult your tax advisor concerning the effects of U.S. federal, state, local and foreign tax laws to you with regard to an investment in our securities.

If a transaction intended to qualify as a Section 1031 Exchange is later determined to be taxable, we may face adverse consequences, and if the laws applicable to such transactions are amended or repealed, we may not be able to dispose of properties on a tax deferred basis.

From time to time we may dispose of properties in transactions that are intended to qualify as Section 1031 Exchanges. It is possible that the qualification of a transaction as a Section 1031 Exchange could be successfully challenged and determined to be currently taxable. In such case, our taxable income and earnings and profits would increase. This could increase the dividend income to our stockholders by reducing any return of capital they received. In some circumstances, we may be required to pay additional dividends or, in lieu of that, corporate income tax, possibly including interest and penalties. As a result, we may be required to borrow funds in order to pay additional dividends or taxes, and the payment of such taxes could cause us to have less cash available to distribute to our stockholders. In addition, if a Section 1031 Exchange were later to be determined to be taxable, we may be required to amend our tax returns for the applicable year in question, including any information reports we sent our stockholders. Moreover, it is possible that legislation could be enacted that could modify or repeal the laws with respect to Section 1031 Exchanges, which could make it more difficult or not possible for us to dispose of properties on a tax deferred basis.

Lease Expirations

We expect to benefit from the re-leasing of 7.5%, or approximately 558,939 rentable square feet, of our Manhattan office leases expiring through December 31, 2016, which we generally believe are currently at below-market rates. During 2013, 2014 and 2015, we have generally been obtaining higher base rents on new and renewed leases at our Manhattan office properties. These increased rents are partly due to an increase in the total rentable square footage of such space as a result of remeasurement and application of market loss factors to our space.

During the year ended December 31, 2015, we entered into new and renewed leases at our Manhattan office properties representing approximately 958,704 rentable square feet. The last weighted average annualized fully escalated gross rent prior to the renewal or re-leasing of these leases was $38.27 per rentable square foot compared to $54.84 per rentable square foot based on the weighted average annualized contractual first monthly base rent (after free rent periods) for the new and renewed leases. During the year ended December 31, 2014, we entered into new and renewed leases at our Manhattan office properties representing approximately 621,224 rentable square feet. The last weighted average annualized fully escalated gross rent prior to the renewal or re-leasing of these leases was $40.86 per rentable square foot compared to $50.42 per rentable square foot based on the weighted average annualized contractual first monthly base rent (after free rent periods) for the new and renewed leases.

The following table sets forth a summary schedule of the lease expirations for leases in place as of December 31, 2015 plus available space for each of the ten calendar years beginning with the year ending December 31, 2016 at the properties in our portfolio. The information set forth in the table assumes that tenants exercise no renewal options and all early termination rights.

Undeveloped Properties

We own entitled land that will support the development of a 17-story, multi-tenanted commercial office building that is expected to comprise approximately 380,000 rentable square feet on 13 floors of office space, which we refer to as Metro Tower. The site is directly adjacent to Metro Center, one of our office properties, and the Stamford Transportation Center. All required zoning approvals have been obtained to allow for development of Metro Tower. We intend to develop this site when we deem the appropriate combination of market and other conditions are in place.

Redevelopment and Repositioning

From 2002 through 2006, we gradually gained full control of the day-to-day management of our Manhattan office properties (with the estate of Leona M. Helmsley previously holding certain approval rights at some of these properties as a result of its interest in the entities owning the properties). Since then, we have been undertaking a comprehensive redevelopment and repositioning strategy of our Manhattan office properties that has included the physical improvement through upgrades and modernization of, and tenant upgrades in, such properties. Since we assumed full control of the day-to-day management of our Manhattan office properties beginning with One Grand Central Place in 2002, and through December 31, 2015, we have invested a total of approximately $645.0 million (excluding tenant improvement costs and leasing commissions) in our Manhattan office properties pursuant to this program. The $645.0 million includes amounts invested at our acquired properties, 1400 Broadway and 111 West 33rd Street (formerly known as 112 West 34th Street). Of the $645.0 million invested pursuant to this program, $331.0 million was invested at the Empire State Building. We currently estimate that between $30.0 million and $50.0 million of capital is needed primarily in 2016 to complete substantially the redevelopment and repositioning program at our Manhattan office properties. We intend to fund these capital improvements through a combination of operating cash flow and borrowings. These estimates are based on our current budgets (which do not include tenant improvement and leasing commission costs) and are subject to change.

tenant amenities. These improvements are designed to improve the overall value and attractiveness of our properties and have contributed significantly to our tenant repositioning efforts, which seek to increase our occupancy; raise our rental rates; increase our rentable square feet; increase our aggregate rental revenue; lengthen our average lease term; increase our average lease size; and improve our tenant credit quality. We have also aggregated smaller spaces in order to offer larger blocks of office space, including multiple floors, that are attractive to larger, higher credit-quality tenants and to offer new, pre-built suites with improved layouts. This strategy has shown what we believe to be attractive results to date, and we believe has the potential to improve our operating margins and cash flows in the future. We believe we will continue to enhance our tenant base and improve rents as our pre-redevelopment leases continue to expire and be re-leased.

Distributions

ESRT intends to pay regular quarterly dividends to holders of its Class A common stock and Class B common stock and we intend to make regular quarterly distributions to our securityholders. Any distributions we or ESRT pay in the future will depend upon our actual results of operations, economic conditions and other factors that could differ materially from our current expectations. Our actual results of operations will be affected by a number of factors, including the revenue we receive from our properties, our operating expenses, interest expense, the ability of our tenants to meet their obligations and unanticipated expenditures. Distributions declared by us will be authorized by ESRT's board of directors in its sole discretion out of funds legally available therefore and will be dependent upon a number of factors, including restrictions under applicable law, our capital requirements and the distribution requirements necessary to maintain ESRT's qualification as a REIT. See Item 1A, "Risk Factors," and Item 7, "Management's Discussion and Analysis of Financial Conditions and Results of Operations," of this Annual Report on Form 10-K, for information regarding the sources of funds used for dividends and for a discussion of factors, if any, which may adversely affect our ability to make distributions to our securityholders.

Securities Authorized For Issuance Under Equity Compensation Plans

During 2013, we adopted our Empire State Realty Trust, Inc. Empire State Realty OP, L.P. 2013 Equity Incentive Plan (the "Plan"). The Plan provides for grants of stock options, shares of restricted ESRT Class A common stock, dividend equivalent rights and other equity-based awards, including LTIP Units, up to an aggregate of 12.2 million shares of our common stock. For a further discussion of the Plan, see Note 11 to the consolidated financial statements included under Item 8 "Financial Statements and Supplementary Data" of this Annual Report on Form 10-K.

______________


(1)	We compute Funds From Operations ("FFO") in accordance with the “White Paper” on FFO published by the National Association of Real Estate Investment Trusts, or NAREIT, which defines FFO as net income (loss) (determined in accordance with GAAP), excluding impairment writedowns of investments in

depreciable real estate and investments in in-substance real estate investments, gains or losses from debt restructurings and sales of depreciable operating properties, plus real estate-related depreciation and amortization (excluding amortization of deferred financing costs), less distributions to non-controlling interests and gains/losses from discontinued operations and after adjustments for unconsolidated partnerships and joint ventures. FFO is a widely recognized non-GAAP financial measure for REITs that we believe, when considered with financial statements determined in accordance with GAAP, is useful to investors in understanding financial performance and providing a relevant basis for comparison among REITs. In addition, FFO is useful to investors as it captures features particular to real estate performance by recognizing that real estate has generally appreciated over time or maintains residual value to a much greater extent than do other depreciable assets. Investors should review FFO, along with GAAP net income, when trying to understand an equity REIT’s operating performance. We present FFO because we consider it an important supplemental measure of our operating performance and believe that it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that results from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of our properties, all of which have real economic effect and could materially impact our results from operations, the utility of FFO as a measure of our performance is limited. There can be no assurance that FFO presented by us is comparable to similarly titled measures of other REITs. FFO does not represent cash generated from operating activities and should not be considered as an alternative to net income (loss) determined in accordance with GAAP or to cash flow from operating activities determined in accordance with GAAP. FFO is not indicative of cash available to fund ongoing cash needs, including the ability to make cash distributions. Although FFO is a measure used for comparability in assessing the performance of REITs, as the NAREIT White Paper only provides guidelines for computing FFO, the computation of FFO may vary from one company to another. For a reconciliation of FFO, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Funds from Operations."

(2)

Modified FFO adds back an adjustment for any above or below-market ground lease amortization to traditionally defined FFO. We consider this a useful supplemental measure in evaluating our operating performance due to the non-cash accounting treatment under GAAP, which stems from the third quarter 2014 acquisition of the two option properties as they carry significantly below market ground leases, the amortization of which is material to our overall results. We present Modified FFO because we consider it an important supplemental measure of our operating performance in that it adds back the non-cash amortization of below-market ground leases. There can be no assurance that Modified FFO presented by us is comparable to similarly titled measures of other REITs. Modified FFO does not represent cash generated from operating activities and should not be considered as an alternative to net income (loss) determined in accordance with GAAP or to cash flow from operating activities determined in accordance with GAAP. Modified FFO is not indicative of cash available to fund ongoing cash needs, including the ability to make cash distributions.

(3)

Core FFO adds back to traditionally defined FFO the following items associated with our initial public offering, or IPO, and formation transactions: gain on consolidation of non-controlling entities, acquisition expenses, severance expenses and retirement equity compensation expenses. It also adds back private perpetual preferred exchange offering expenses, acquisition expenses, prepayment penalty and deferred financing costs write-off and gain on settlement of lawsuit related to the Observatory, net of income taxes and ground lease amortization, construction severance expenses and acquisition break-up fee. We present Core FFO because we consider it an important supplemental measure of our operating performance in that it excludes items associated with the Offering and formation transactions. There can be no assurance that Core FFO presented by us is comparable to similarly titled measures of other REITs. Core FFO does not represent cash generated from operating activities and should not be considered as an alternative to net income (loss) determined in accordance with GAAP or to cash flow from operating activities determined in accordance with GAAP. Core FFO is not indicative of cash available to fund ongoing cash needs, including the ability to make cash distributions. For a reconciliation of Core FFO, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Core Funds from Operations."

Overview

Unless the context otherwise requires or indicates, references in this section to our company, we, our and us refer to (i) Empire State Realty OP, L.P. and its consolidated subsidiaries after giving effect to ESRT's initial public offering, or the Offering, and the formation transactions and (ii) our predecessor before giving effect to the Offering and the formation transactions.

With the completion of the Offering and the formation transactions, the historical operations of our predecessor and the properties that have been operated through our predecessor, were combined with our company and/or our subsidiaries. The following discussion and analysis should be read in conjunction with "Selected Financial Data," and our consolidated financial statements as of December 31, 2015 and 2014 and for the years ended December 31, 2015, 2014 and 2013 and the notes related thereto which are included in this Annual Report on Form 10-K.

2015 Highlights


•	Achieved Core FFO of $0.97 per fully diluted share and net income attributable to the Company of $0.29 per fully diluted share.

•

Executed 245 leases, representing 1,209,145 rentable square feet across the total portfolio, achieving a 73.7% increase in mark-to-market rent over previously fully escalated rents on new, renewal, and expansion leases; 177 of these leases, representing 958,704 rentable square feet, were within the Manhattan office portfolio (excluding the retail component of these properties) capturing a 43.3% increase in mark-to-market rent over previously fully escalated rents on new, renewal and expansion leases.


•	Executed 12 leases, representing 70,940 rentable square feet within the Manhattan retail portfolio, achieving a 474.1% increase in mark-to-market rent over previously fully escalated rents on new, renewal, and expansion leases.


•	Signed 93 new leases representing 728,264 rentable square feet in 2015 for the Manhattan office portfolio (excluding the retail component of these properties), achieving an increase of 53.8% in mark-to-market rent over expired previously fully escalated rents.


•	The Empire State Building Observatory revenue grew 0.6% to $112.2 million from $111.5 million in 2014.


•	Declared and paid aggregate dividends of $0.34 per share during 2015.


•	Recast our $800 million corporate credit facility, converting it from a secured to an unsecured facility, reducing its interest rate and extending its maturity by one year.


•	Completed a private placement of $350 million aggregate principal amount of senior unsecured notes with a blended 12.5 year average life and 4.08% coupon.


•	Closed on a new seven year $265.0 million senior unsecured term loan facility.


•	Repaid a $44 million mortgage loan on 1359 Broadway and a $91 million mortgage loan on One Grand Central Place.

As of December 31, 2015, our total portfolio, containing 10.1 million rentable square feet of office and retail space, was 87.3% occupied. Including signed leases not yet commenced, our total portfolio was 89.1% leased at December 31, 2015. Our Manhattan area office properties were 84.9% occupied (or 87.2% giving effect to leases signed but not yet commenced as of that date) and our greater New York metropolitan area office properties were 93.9% occupied (or 94.2% giving effect to leases signed but not yet commenced as of that date). Our office properties as a whole were 86.7% occupied (or 88.6% giving effect to leases signed but not yet commenced as of that date). Our ability to increase occupancy and rental revenue at our office properties depends on the successful completion of our repositioning program as described below and market conditions. The other component of our real estate segment, retail leasing, comprises both standalone retail properties and retail space in our Manhattan office properties. Our retail properties, including retail space in our Manhattan office properties, were 94.3% occupied (or 94.6% giving effect to leases signed but not yet commenced as of that date) as of December 31, 2015.

The Empire State Building is our flagship property. The Empire State Building provides us with a diverse source of revenue through its office and retail leases, observatory operations and broadcasting licenses, and related leased space. Our observatory operations is a separate accounting segment following the Offering and related formation transactions. Our observatory operations are subject to regular patterns of tourist activity in Manhattan. During the past ten years of our annual observatory revenue, approximately 16% to 18% was realized in the first quarter, 26.0% to 28.0% was realized in the second quarter, 31.0% to 33.0% was realized in the third quarter, and 23.0% to 25.0% was realized in the fourth quarter. The components of the Empire State Building revenue are as follows (dollars in thousands):



	Year Ended December 31,
	2015				2014
Office leases	$	108,873	37.5	%	$	105,922	37.4	%
Retail leases	11,092		3.8	%	9,663		3.4	%
Tenant reimbursements & other income	37,021		12.8	%	35,593		12.5	%
Observatory operations	112,172		38.7	%	111,541		39.4	%
Broadcasting licenses and leases	20,877		7.2	%	20,575		7.3	%
Total	$	290,035	100.0	%	$	283,294	100.0	%

From 2002 through 2006, we gradually gained full control of the day-to-day management of our Manhattan office properties (with the estate of Leona M. Helmsley previously holding certain approval rights at some of these properties as a result of its interest in the entities owning the properties). Since then, we have been undertaking a comprehensive redevelopment and repositioning strategy of our Manhattan office properties that has included the physical improvement through upgrades and modernization of, and tenant upgrades in, such properties. Since we assumed full control of the day-to-day management of our Manhattan office properties beginning with One Grand Central Place in 2002, and through December 31, 2015, we have invested a total of approximately $645.0 million (excluding tenant improvement costs and leasing commissions) in our Manhattan office properties pursuant to this program. The $645.0 million includes amounts invested at our recently acquired properties, 1400 Broadway and 111 West 33rd Street (formerly known as 112 West 34th Street). Of the $645.0 million invested pursuant to this program, $331.0 million was invested at the Empire State Building. We currently estimate that between $30.0 million and $50.0 million of capital is needed primarily in 2016 to complete substantially the redevelopment and repositioning program at our Manhattan office properties. We intend to fund these capital improvements through a combination of operating cash flow and borrowings. These estimates are based on our current budgets (which do not include tenant improvement and leasing commission costs) and are subject to change.

These improvements, within our redevelopment and repositioning program, include restored, renovated and upgraded or new lobbies; elevator modernization; renovated public areas and bathrooms; refurbished or new windows; upgrade and standardization of retail storefront and signage; façade restorations; modernization of building-wide systems; and enhanced tenant amenities. These improvements are designed to improve the overall value and attractiveness of our properties and have contributed significantly to our tenant repositioning efforts, which seek to increase our occupancy; raise our rental rates; increase our rentable square feet; increase our aggregate rental revenue; lengthen our average lease term; increase our average lease size; and improve our tenant credit quality. We have also aggregated smaller spaces in order to offer larger blocks of office space, including multiple floors, that are attractive to larger, higher credit-quality tenants and to offer new, pre-built suites with improved layouts. This strategy has shown what we believe to be attractive results to date, and we believe has the potential

to improve our operating margins and cash flows in the future. We believe we will continue to enhance our tenant base and improve rents as our pre-redevelopment leases continue to expire and be re-leased.

As of December 31, 2015, excluding principal amortization, we have no debt maturing in 2016 and approximately $355.8 million of debt maturing in 2017, and we have total debt outstanding of approximately $1.6 billion, with a weighted average interest rate of 4.12% (excluding premiums and discount) and a weighted average maturity of 5.4 years and 81.4% of which is fixed-rate indebtedness. Our consolidated debt to total market capitalization was approximately 25% as of December 31, 2015.

As of March 27, 2015, we no longer solicited new business for our construction management business. We completed all projects that were in progress.

Net income attributable to common unit holders	$	78,992		$	69,734		$	9,258		13.3	%

Rental Revenue

The increase in rental income was primarily attributable to the acquisition of two properties during July 2014 which increased rental income by $38.6 million. The remaining increase is primarily due to increased rental rates.

Tenant Expense Reimbursement

The increase in tenant expense reimbursement was primarily attributable to the acquisition of two properties during July 2014 which increased tenant expense reimbursements by $6.1 million. Higher real estate tax reimbursements, electric submeter expense reimbursements and cleaning reimbursements also contributed to the increase.

Observatory Revenue

2015 Observatory revenues were consistent with the 2014 revenues.

Construction Revenue

The construction business ceased operations during 2015 which is reflected in the decline in construction revenues.

Third-Party Management and Other Fees

The decrease in third party management and other fees revenue was primarily due to the acquisition of two properties during July 2014 and the subsequent elimination of fees due to the consolidation of these properties.

Other Revenues and Fees

The decrease in other revenues and fees was primarily due to lower lease cancellation income of $4.1 million offset by $2.5 million acquisition break-up fee income and increased parking income of $0.7 million.

Property Operating Expenses

The increase in property operating expenses was primarily attributable to the acquisition of two properties during July 2014 which increased property operating expenses by $10.1 million.

Ground Rent Expenses

The increase in ground rent expenses was attributable to the acquisition of two properties during July 2014.

Marketing, General and Administrative Expenses

The variance is primarily due to private perpetual preferred exchange offering costs of $1.4 million which were incurred in the year ended 2014 and no such costs in 2015.

Observatory Expenses

2015 Observatory expenses were consistent with the 2014 expenses.

Construction Expenses

The decline in construction expenses correlates with the lower revenues due to the construction business ceasing operation in 2015. Construction expenses in 2015 included severance expenses of $0.9 million.

Real Estate Taxes

The increase in real estate taxes was primarily attributable to the acquisition of two properties during July 2014 which increased real estate taxes by $5.9 million, as well as higher taxes of $5.1 million resulting from higher assessed values and rates for several properties.

Acquisition Expenses

The decrease in acquisition expenses was primarily attributable to the acquisition of two properties during July 2014.

Depreciation and Amortization

The increase in depreciation and amortization was primarily attributable to the acquisition of two properties during July 2014 which increased depreciation and amortization by $23.4 million.

Interest Expense

The increase in interest expense was attributable to the acquisition of two properties during July 2014 and the write-off of $1.7 million of deferred finance costs related to the recast of the credit facility and the early repayments of mortgage loans. These higher expenses were partially offset by reductions in interest rates for debt refinanced during 2014 and 2015.

Income taxes

Income taxes decreased due to taxable income activities within our TRSs, primarily lower taxable income related to our construction operations and Observatory operations.

Private Perpetual Preferred Unit Distributions

Represents distributions to holders of private perpetual preferred units, which were issued in August 2014.

transactions. See Footnote 1 “Description of Business and Organization” to the financial statements of this Annual Report in Form 10-K for a description of the Offering and formation transactions. Our operations commenced upon completion of the Offering and related formation transactions on October 7, 2013. Consequently, the results of operations for 2013 reflect a partial year and are not comparable to the results of operations for the full year 2014.

Acquisition Expenses

Acquisition expenses decreased by $134.8 million due to the completion of the formation transactions in 2013. Acquisition expenses in 2014 are attributable to the acquisition of two properties during July 2014.

Gain on Consolidation of Non-controlled Entities

The gain on consolidation of non-controlled entities in 2013 reflects gains associated with the acquisition of the four non-controlled properties upon the completion of the Offering and related formation transactions on October 7, 2013. The gain was primarily a result of the fair value exceeding the book value of our predecessor ownership interests in the four non-controlled entities plus the elimination of the intercompany ground and building leases.

Income taxes

Income taxes increased due to taxable income activities within our TRSs, primarily taxable income related to our Observatory operations, third party management fees, construction income, and certain cleaning income.

Private Perpetual Preferred Unit Distributions

Represents distributions to holders of private perpetual preferred units, which were issued in August 2014.

(1)	Not meaningful.

We did not have any meaningful operating activity until the consummation of the Offering and the related acquisition of our predecessor and certain non-controlled entities controlled by our predecessor on October 7, 2013 as part of the formation transactions. See Footnote 1 “Description of Business and Organization” to the financial statements of this Annual Report in Form 10-K for a description of the Offering and formation transactions. Our operations commenced upon completion of the Offering and related formation transactions on October 7, 2013. Consequently, our Predecessor's results of operations for 2013 reflect a partial year and are not comparable to the results of operations for the full year 2014.

Formation transaction expenses

The expenses incurred in 2013 reflect costs associated with the formation of our company.

Acquisition Expenses

Acquisition expenses in 2014 are attributable to the acquisition of two properties during July 2014.

Equity in net income of non-controlling entities

Reflects net income from the Predecessor's investments in four non-controlled entities. These entities were acquired by us during the formation transactions.

Settlement Expense

Settlement expense of $55.0 million reflects costs associated with the settlement of litigation during the year ended December 31, 2013. On September 28, 2012, a Stipulation of Settlement resolving the Original Class Actions was entered into. The terms of the settlement include, amongst other things, a payment of $55.0 million, with a minimum of 80% in cash and a maximum of 20% in freely-tradable shares of common stock and/or operating partnership units. As the payment is to be fully made by the principal owners of certain predecessor entities, $55.0 million was recorded as settlement expense in our predecessor's statement of operations, with a corresponding $55.0 million capital contribution to our predecessor at that time.

Income taxes

Income taxes are due to taxable income activities within our TRSs, primarily taxable income related to our Observatory operations, third party management fees, construction income, and certain cleaning income.

Private Perpetual Preferred Unit Distributions

Represents distributions to holders of private perpetual preferred units, which were issued in August 2014.

Liquidity and Capital Resources

At December 31, 2015, we had approximately $46.7 million available in cash and cash equivalents and there was $760.0 million available under our unsecured revolving credit facility.

Liquidity is a measure of our ability to meet potential cash requirements, including ongoing commitments to repay borrowings, fund and maintain our assets and operations, including lease-up costs, fund our redevelopment and repositioning programs, acquire properties, make distributions to our securityholders and other general business needs. Based on the historical experience of our management and our business strategy, in the foreseeable future we anticipate we will generate positive cash flows from operations. In order for ESRT to qualify as a REIT, ESRT is required under the Code to distribute to its securityholders, on an annual basis, at least 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains. We expect to make quarterly distributions to our securityholders.

While we may be able to anticipate and plan for certain liquidity needs, there may be unexpected increases in uses of cash that are beyond our control and which would affect our financial condition and results of operations. For example, we may be required to comply with new laws or regulations that cause us to incur unanticipated capital expenditures for our properties, thereby increasing our liquidity needs. Even if there are no material changes to our anticipated liquidity requirements, our sources of liquidity may be fewer than, and the funds available from such sources may be less than, anticipated or needed. Our primary sources of liquidity will generally consist of cash on hand and cash generated from our operating activities, mortgage financings and unused borrowing capacity under our secured revolving and term credit facility. We expect to meet our short-term liquidity requirements, including distributions, operating expenses, working capital, debt service, and capital expenditures from cash flows from operations, debt issuances, and available borrowing capacity under our unsecured revolving credit facility. The availability of these borrowings is subject to the conditions set forth in the applicable loan agreements. We expect to meet our long-term capital requirements, including acquisitions, redevelopments and capital expenditures through our cash flows from operations, our unsecured revolving credit facility, mortgage financings, debt issuances, common and/or preferred equity issuances and asset sales. Our properties require periodic investments of capital for individual lease related tenant improvements allowances, general capital improvements and costs associated with capital expenditures. Our overall leverage will depend on our mix of investments and the cost of leverage. ESRT's charter does not restrict the amount of leverage that we may use.

As of December 31, 2015, we had approximately $1.6 billion of total consolidated indebtedness outstanding, with a weighted average interest rate of 4.12% and a weighted average maturity of 5.4 years. As of December 31, 2015, exclusive of principal amortization, we have no maturities in 2016 and approximately $355.8 million of debt maturing in 2017. Given our current liquidity, including availability under our unsecured revolving credit facility, we believe we will be able to refinance the maturing debt.

Unsecured Revolving Credit Facility

On January 23, 2015, we entered into an unsecured revolving credit agreement, which is referred to herein as the “unsecured revolving credit facility,” with Bank of America, Merrill Lynch, Goldman Sachs and the other lenders party thereto. Merrill Lynch acted as joint lead arranger; Bank of America acted as administrative agent; and Goldman Sachs acted as syndication agent and joint lead arranger.

Concurrently with the entering into the unsecured revolving credit facility, on January 23, 2015, we terminated our previous secured revolving and term credit facility. In connection with the termination of the secured revolving and term credit facility, all of the guarantors thereunder were released from their guaranty obligations, all liens created thereby were terminated, and all collateral pledged thereunder was released.

Amount. The unsecured revolving credit facility is comprised of a revolving credit facility in the maximum original principal amount of $800.0 million. The unsecured revolving credit facility contains an accordion feature that would allow us to increase the maximum aggregate principal amount to $1.25 billion under specified circumstances.

Guarantors. Certain of our subsidiaries are guarantors of our obligations under the unsecured revolving credit facility.

Interest. Amounts outstanding under the unsecured revolving credit facility will bear interest at a floating rate equal to, at our election, (x) a Eurodollar rate, plus a spread that we expect will range from 0.875% to 1.600% depending upon its leverage ratio and credit rating; or (y) a base rate, plus a spread that we expect will range from 0.000% to 0.600% depending upon its leverage ratio and credit rating. In addition, the unsecured revolving credit facility permits us to borrow at competitive bid rates determined in accordance with the procedures described in the unsecured revolving credit facility.

Maturity. The unsecured revolving credit facility has an initial maturity of January 2019. We have the option to extend the initial term of the unsecured revolving credit facility for up to two additional six-month periods, subject to certain conditions, including the payment of an extension fee equal to 0.075% of the then outstanding commitments under the unsecured revolving credit facility.

Financial Covenants. The unsecured revolving credit facility includes the following financial covenants: (i) maximum leverage ratio of total indebtedness to total asset value of the loan parties and their consolidated subsidiaries will not exceed 60%, (ii) consolidated secured indebtedness will not exceed 40% of total asset value, (iii) tangible net worth will not be less than $745.4 million plus 75% of net equity proceeds received by the operating partnership (other than proceeds received within ninety (90) days after the redemption, retirement or repurchase of ownership or equity interests in the operating partnership up to the amount paid by the operating partnership in connection with such redemption, retirement or repurchase, where, the net effect is that the operating partnership shall not have increased its net worth as a result of any such proceeds), (iv) adjusted EBITDA (as defined in the unsecured revolving credit facility) to consolidated fixed charges will not be less than 1.50x, (v) the aggregate net operating income with respect to all unencumbered eligible properties to the portion of interest expense attributable to unsecured indebtedness will not be less than 1.75x, (vi) the ratio of total unsecured indebtedness to unencumbered asset value will not exceed 60%, and (vii) consolidated secured recourse indebtedness will not exceed 10% of total asset value (provided, however, this covenant shall not apply at any time after either the company or the operating partnership achieves a debt ratings from at least two of Moody’s, S&P and Fitch, and such debt ratings are Baa3 or better (in the case of a rating by Moody’s) or BBB- or better (in the case of a rating by S&P or Fitch)). As of December 31, 2015, we were in compliance with the covenants:



Financial covenant	Required		December 31, 2015			In Compliance
Maximum total leverage	< 60%		29.8		%	Yes
Maximum secured debt	< 40%		13.6		%	Yes
Minimum fixed charge coverage	> 1.50x		4.0x			Yes
Minimum unencumbered interest coverage	> 1.75x		7.3x			Yes
Maximum unsecured leverage	< 60%		25.0		%	Yes
Maximum secured recourse indebtedness	<10%		—		%	Yes
Minimum tangible net worth	$	745,356	$	969,060		Yes

Other Covenants. The unsecured revolving credit facility contains customary covenants, including limitations on liens, investment, debt, fundamental changes, and transactions with affiliates, and will require certain customary financial reports.

Events of Default. The unsecured revolving credit facility contains customary events of default (subject in certain cases to specified cure periods), including but not limited to non-payment, breach of covenants, representations or warranties, cross defaults, bankruptcy or other insolvency events, judgments, ERISA events, invalidity of loan documents, loss of real estate investment trust qualification, and occurrence of a change of control (defined in the definitive documentation for the unsecured credit facility).

Secured Revolving and Term Credit Facility

As of December 31, 2014, the secured revolving and term credit facility had an outstanding balance of $470.0 million. The secured revolving and term credit facility was terminated on January 23, 2015 concurrent with entering into the unsecured revolving credit facility described above.

Senior Unsecured Notes

During March 2015, we issued and sold an aggregate principal amount of $350.0 million of senior unsecured notes ("Series A, B and C Senior Notes") in a private placement to entities affiliated with Prudential Capital Group. The Series A, B and C Senior Notes consist of $100 million of 3.93% Series A Senior Notes due 2025, $125 million of 4.09% Series B Senior Notes due 2027, and $125 million of 4.18% Series C Senior Notes due 2030. The proceeds were used to repay outstanding mortgage debt, to reduce amounts outstanding under our unsecured credit facility and for other general corporate purposes.

The Series A, B and C Senior Notes are senior unsecured obligations and are unconditionally guaranteed by each of our subsidiaries that guarantees indebtedness under the senior unsecured revolving credit facility. Interest on the Series A, B and C Senior Notes is payable quarterly.

The terms of the Series A, B and C Senior Notes include customary covenants, including limitations on liens, investment, debt, fundamental changes, and transactions with affiliates and will require certain customary financial reports. It also requires compliance with financial ratios consistent with the unsecured credit facility including a maximum leverage ratio, a maximum secured leverage ratio, a minimum amount of tangible net worth, a minimum fixed charge coverage ratio, a minimum unencumbered interest coverage ratio, a maximum unsecured leverage ratio and a maximum amount of secured recourse indebtedness. As of December 31, 2015, we were in compliance with the covenants under the Series A, B and C Senior Notes.

Unsecured Term Loan Facility

During August 2015, we closed on a seven year $265.0 million senior unsecured term loan facility ("term loan facility"). The term loan facility matures on August 24, 2022. The term loan facility bears interest at a floating rate equal to, at our election, a LIBOR rate, plus a spread ranging from 1.400% to 2.350%; or a base rate, plus a spread ranging from 0.400% to 1.350%, in each case such spread is determined by our leverage ratio and credit rating. Pursuant to a forward interest rate swap agreement, we effectively fixed LIBOR at 2.1485% for $265.0 million of the term loan facility for the period from August 31, 2017 through maturity. The proceeds were used to repay borrowings made under our unsecured revolving credit facility.

The terms of the term loan facility agreement include customary covenants, including limitations on liens, investment, debt, fundamental changes, and transactions with affiliates and will require certain customary financial reports. It requires compliance with financial ratios including a maximum leverage ratio, a maximum secured leverage ratio, a minimum amount of tangible net worth, a minimum fixed charge coverage ratio, a minimum unencumbered interest coverage ratio, a maximum unsecured leverage ratio and a maximum amount of secured recourse indebtedness. It also contains customary events of default (subject in certain cases to specified cure periods). These terms in the term loan facility agreement are consistent with the terms under our unsecured revolving credit facility agreement. As of December 31, 2015, we were in compliance with the covenants under the term loan facility.

Senior Unsecured Notes - Exchangeable

During August 2014, we issued $250.0 million principal amount of 2.625% Exchangeable Senior Notes (“Senior Notes”) due August 2019. In connection with this offering, we received net proceeds of $246.9 million, after deducting the related underwriting discounts and commissions and issuance costs.

Mortgage debt

As of December 31, 2015, we had mortgage debt outstanding of $747.7 million.

During 2015,


(i)	we repaid a mortgage collateralized by 1359 Broadway; and


(ii)	we repaid a mortgage collateralized by One Grand Central Place.

During 2014,


(i)	we refinanced early the Metro Center mortgage loan with a new $100.0 million mortgage loan due 2024 which bears interest at a fixed rate of 3.59% and a 30 year amortization;


(ii)	we repaid the second lien mortgage collateralized by 1350 Broadway;


(iii)	we repaid the first and second lien mortgages collateralized by 501 Seventh Avenue;


(iv)	we repaid a mortgage collateralized by 500 Mamaroneck Avenue, and


(v)	we refinanced the three One Grand Central Place mortgage loans with a new $91.0 million mortgage loan due 2017 which bears interest at LIBOR plus 1.35%.

Leverage Policies

We expect to employ leverage in our capital structure in amounts determined from time to time by our board of directors. Although ESRT's board of directors has not adopted a policy that limits the total amount of indebtedness that we may incur, we anticipate that ESRT's board of directors will consider a number of factors in evaluating our level of indebtedness from time to time, as well as the amount of such indebtedness that will be either fixed or floating rate. ESRT's charter and bylaws do not limit the amount or percentage of indebtedness that we may incur nor do they restrict the form in which our indebtedness will be taken (including, but not limited to, recourse or non-recourse debt and cross collateralized debt). Our overall leverage will depend on our mix of investments and the cost of leverage, however, we initially intend to maintain a level of indebtedness consistent with our plan to seek an investment grade credit rating. ESRT's board of directors may from time to time modify our leverage policies in light of the then-current economic conditions, relative costs of debt and equity capital, market values of our properties, general market conditions for debt and equity securities, fluctuations in the market price of ESRT's common stock and our traded OP units, growth and acquisition opportunities and other factors.

Capital expenditures

The following tables summarize our tenant improvement costs, leasing commission costs and our capital expenditures for our 20 properties as if they were consolidated for each of the periods presented (dollars in thousands, except per square foot amounts).

_______________


(1)	Includes all capital expenditures, excluding tenant improvements and leasing commission costs, which are primarily attributable to the redevelopment and repositioning program conducted at our Manhattan office properties.

As of December 31, 2015, we expect to incur additional costs relating to obligations under signed new leases of approximately $51.2 million during the year ending December 31, 2016. This consists of approximately $50.8 million for tenant improvements and other improvements related to new leases and approximately $0.4 million on leasing commissions expected to be incurred in the year ending December 31, 2016. We intend to fund the tenant improvements and leasing commission costs through a combination of operating cash flow and borrowings under the secured revolving and term credit facility.

Capital expenditures are considered part of both our short-term and long-term liquidity requirements. We currently estimate that between $30.0 million and $50.0 million of capital is needed primarily in 2016 to complete substantially the redevelopment program at our Manhattan office properties, which we expect to occur by the end of 2016. However, these estimates are based on current budgets and are subject to change. We intend to fund the capital improvements to complete the redevelopment and repositioning program through a combination of operating cash flow and borrowings under the unsecured revolving credit facility.

(2)	Does not include various standing or renewal service contracts with vendors related to our property management.

Off-Balance Sheet Arrangements

As of December 31, 2015, we did not have any off-balance sheet arrangements.

Distribution Policy

Before we pay any distribution, we must first meet both our operating requirements and obligations to make payments of principal and interest, if any. However, under some circumstances, we may be required to use cash reserves, incur debt or liquidate assets at rates or times that we regard as unfavorable in order to allow ESRT to satisfy its REIT 90% distribution requirement and to avoid U.S. federal income tax and the 4% nondeductible excise tax in that year.

Distribution to Equity Holders

Distributions and dividends have been made to equity holders in 2013, 2014 and 2015 as follows (amounts in thousands):



Period from October 7, 2013 through December 31, 2013	$	19,516

Cash Flows

Comparison of Year Ended December 31, 2015 to the Year Ended December 31, 2014

Net cash. Cash on hand was $46.7 million and $45.7 million, respectively, as of December 31, 2015 and 2014.

Operating activities. Net cash provided by operating activities increased by $64.6 million to $203.2 million for the year ended December 31, 2015 compared to $138.6 million for the year ended December 31, 2014. This is primarily due to the acquisition of two properties in July 2014 and the expirations of free rent periods.

Investing activities. Net cash used in investing activities decreased by $156.8 million to $142.3 million for the year ended December 31, 2015 compared to $299.1 million for the year ended December 31, 2014. The decrease is primarily due to the acquisition of two properties in 2014 partially offset by higher expenditures on tenant improvements.

Financing activities. Net cash (used in) provided by financing activities decreased by $205.4 million to $(59.9) million for the year ended December 31, 2015 compared to $145.5 million for the year ended December 31, 2014. The decrease is primarily due to financing associated with the acquisition of two properties in 2014.

Comparison of Year Ended December 31, 2014 to the Period from October 7, 2013 through December 31, 2013

We did not have any meaningful operating activity until the consummation of the Offering and the related acquisition of our predecessor and certain non-controlled entities controlled by our predecessor on October 7, 2013 as part of the formation transactions. See Footnote 1 “Description of Business and Organization” to the financial statements of this Annual Report in Form 10-K for a description of the Offering and formation transactions. Our operations commenced upon completion of the Offering and related formation transactions on October 7, 2013. Consequently, the cash flows for 2013 reflect the period from October 7, 2013 through December 31, 2013 and are not comparable to the cash flows for the full year 2014.

Net Operating Income

Our financial reports include a discussion of property net operating income, or NOI. NOI is a non-GAAP financial measure of performance. NOI is used by investors and our management to evaluate and compare the performance of our properties and to determine trends in earnings and to compute the fair value of our properties as it is not affected by; (i) the cost of funds of the property owner, (i) the impact of depreciation and amortization expenses as well as gains or losses from the sale of operating real estate assets that are included in net income computed in accordance with GAAP, (iii) acquisition expenses and formation transaction expenses, or (iv) general and administrative expenses and other gains and losses that are specific to the property owner. The cost of funds is eliminated from net operating income because it is specific to the particular financing capabilities and constraints of the owner. The cost of funds is also eliminated because it is dependent on historical interest rates and other costs of capital as well as past decisions made by us regarding the appropriate mix of capital which may have changed or may change in the future. Depreciation and amortization expenses as well as gains or losses from the sale of operating real estate assets are eliminated because they may not accurately represent the actual change in value in our office or retail properties that result from use of the properties or changes in market conditions. While certain aspects of real property do decline in value over time in a manner that is reasonably captured by depreciation and amortization, the value of the properties as a whole have historically increased or decreased as a result of changes in overall economic conditions instead of from actual use of the property or the passage of time. Gains and losses from the sale of real property vary from property to property and are affected by market conditions at the time of sale which will usually change from period to period. These gains and losses can create distortions when comparing one period to another or when comparing our operating results to the operating results of other real estate companies that have not made similarly timed, purchases or sales. We believe that eliminating these costs from net income is useful because the resulting measure captures the actual revenue, generated and actual expenses incurred in operating our properties as well as trends in occupancy rates, rental rates and operating costs.

However, the usefulness of NOI is limited because it excludes general and administrative costs, interest expense, interest income and other expense, depreciation and amortization expense and gains or losses from the sale of properties, and other gains and losses as stipulated by GAAP, the level of capital expenditures and leasing costs necessary to maintain the operating performance of our properties, all of which are significant economic costs. NOI may fail to capture significant trends in these components of net income which further limits its usefulness.

NOI is a measure of the operating performance of our properties but does not measure our performance as a whole. NOI is therefore not a substitute for net income as computed in accordance with GAAP. This measure should be analyzed in conjunction with net income computed in accordance with GAAP and discussions elsewhere in this Management’s Discussion and Analysis of Financial Condition and Results of Operations regarding the components of net income that are eliminated in the calculation of NOI. Other companies may use different methods for calculating NOI or similarly entitled measures and, accordingly, our NOI may not-be comparable to similarly entitled measures reported by other companies that do not define the measure exactly as we do.

The following table presents a reconciliation of our company and predecessor net income, the most directly comparable GAAP measure, to NOI for the periods presented (amounts in thousands):

Funds from Operations ("FFO")

We present below a discussion of FFO. We compute FFO in accordance with the “White Paper” on FFO published by the National Association of Real Estate Investment Trusts, or NAREIT, which defines FFO as net income (loss) (determined in accordance with GAAP), excluding impairment writedowns of investments in depreciable real estate and investments in in-substance real estate investments, gains or losses from debt restructurings and sales of depreciable operating properties, plus real estate-related depreciation and amortization (excluding amortization of deferred financing costs), less distributions to non-controlling interests and gains/losses from discontinued operations and after adjustments for unconsolidated partnerships and joint ventures. FFO is a widely recognized non-GAAP financial measure for REITs that we believe, when considered with financial statements determined in accordance with GAAP, is useful to investors in understanding financial performance and providing a relevant basis for comparison among REITS. In addition, FFO is useful to investors as it captures features particular to real estate performance by recognizing that real estate has generally appreciated over time or maintains residual value to a much greater extent than do other depreciable assets. Investors should review FFO, along with GAAP net income, when trying to understand an equity REIT’s operating performance. We present FFO because we consider it an important supplemental measure of our operating performance and believe that it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs. However, because FFO excludes depreciation and amortization and captures neither the changes in the value of our properties that result from use or market conditions nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of

our properties, all of which have real economic effect and could materially impact our results of operations, the utility of FFO as a measure of its performance is limited. There can be no assurance that FFO presented by us is comparable to similarly titled measures of other REITs. FFO does not represent cash generated from operating activities and should not be considered as an alternative to net income (loss) determined in accordance with GAAP or to cash flow from operating activities determined in accordance with GAAP. FFO is not indicative of cash available to fund ongoing cash needs, including the ability to make cash distributions. Although FFO is a measure used for comparability in assessing the performance of REITs, as the NAREIT White Paper only provides guidelines for computing FFO, the computation of FFO may vary from one company to another.

Modified Funds From Operations ("Modified FFO")

Core Funds From Operations ("Core FFO")

Core FFO adds back to traditionally defined FFO the following items associated with the Company's initial public offering, or IPO, and formation transactions: gain on consolidation of non-controlling entities, acquisition expenses, severance expenses and retirement equity compensation expenses. It also adds back private perpetual preferred exchange offering expenses, prepayment penalty expense, deferred financing costs write-off, acquisition expenses, gain on settlement of lawsuit related to the Observatory, net of income taxes, ground lease amortization, construction severance expenses and acquisition break-up fee. The Company presents Core FFO because it considers it an important supplemental measure of its operating performance in that it excludes items associated with its IPO and formation transactions and other non-recurring items. There can be no assurance that Core FFO presented by the Company is comparable to similarly titled measures of other REITs. Core FFO does not represent cash generated from operating activities and should not be considered as an alternative to net income (loss) determined in accordance with GAAP or to cash flow from operating activities determined in accordance with GAAP. Core FFO is not indicative of cash available to fund ongoing cash needs, including the ability to make cash distributions. In future periods, we may also exclude other items from Core FFO that we believe may help investors compare our results.

The following table presents a reconciliation of our company and predecessor net income (loss), the most directly comparable GAAP measure, to FFO and Core FFO for the periods presented (amounts in thousands, except per unit amounts):

Factors That May Influence Future Results of Operations

Rental Revenue

We derive revenues primarily from rents, rent escalations, expense reimbursements and other income received from tenants under existing leases at each of our properties. “Escalations and expense reimbursements” consist of payments made by tenants to us under contractual lease obligations to reimburse a portion of the property operating expenses and real estate taxes incurred at each property.

We believe that the average rental rates for in-place leases at our properties are generally below the current market rates, although individual leases at particular properties presently may be leased above, at or below the current market rates within its particular submarket.

The amount of net rental income and reimbursements that we receive depends principally on our ability to lease currently available space, re-lease space to new tenants upon the scheduled or unscheduled termination of leases or renew expiring leases and to maintain or increase our rental rates. Factors that could affect our rental incomes include, but are not limited to: local, regional or national economic conditions; an oversupply of, or a reduction in demand for, office or retail space; changes in market rental rates; our ability to provide adequate services and maintenance at our properties; and fluctuations in interest rates could adversely affect our rental income in future periods. Future economic or regional downturns affecting our submarkets or downturns in our tenants’ industries could impair our ability to lease vacant space and renew or re-lease space as well as the ability of our tenants to fulfill their lease commitments, and could adversely affect our ability to maintain or increase the occupancy at our properties.

Tenant Credit Risk

The economic condition of our tenants may also deteriorate, which could negatively impact their ability to fulfill their lease commitments and in turn adversely affect our ability to maintain or increase the occupancy level and/or rental rates of our properties. Potential tenants may look to consolidate, reduce overhead and preserve operating capital and may also defer strategic decisions, including entering into new, long-term leases at properties.

Leasing

On a combined basis, we, our predecessor and the non-controlled entities, signed 1.2 million, 0.8 million, and 1.1 million rentable square feet of new leases, expansions and lease renewals, for the years ended December 31, 2015, 2014, and 2013, respectively.

Due to the relatively small number of leases that are signed in any particular quarter, one or more larger leases may have a disproportionately positive or negative impact on average rent, tenant improvement and leasing commission costs for that period. As a result, we believe it is more appropriate when analyzing trends in average rent and tenant improvement and leasing commission costs to review activity over multiple quarters or years. Tenant improvement costs include expenditures for general improvements occurring concurrently with, but that are not directly related to, the cost of installing a new tenant. Leasing commission costs are similarly subject to significant fluctuations depending upon the length of leases being signed and the mix of tenants from quarter to quarter.

As of December 31, 2015, there were approximately 1.1 million rentable square feet of space in our portfolio available to lease (excluding leases signed but not yet commenced) representing 10.9% of the net rentable square footage of the properties in our portfolio. In addition, leases representing 7.7% and 7.3% of net rentable square footage of the properties in our portfolio will expire in 2016 and in 2017, respectively. These leases are expected to represent approximately 8.1% and 8.1%, respectively, of our annualized rent for such periods. Our revenues and results of operations can be impacted by expiring leases that are not renewed or re-leased or that are renewed or re-leased at base rental rates equal to above or below the current average base rental rates. Further, our revenues and results of operations can also be affected by the costs we incur to re-lease available space, including payment of leasing commissions, redevelopments and build-to-suit remodeling that may not be borne by the tenant.

We believe that as we complete the redevelopment and repositioning of our properties we will, over the long-term, experience increased occupancy levels and rents. Over the short term, as we renovate and reposition our properties, which includes aggregating smaller spaces to offer large blocks of space, we may experience lower occupancy levels as a result of having to relocate tenants to alternative space and the strategic expiration of existing leases. We believe that despite the short-term lower occupancy levels we may experience, we will continue to experience increased rental revenues as a result of the increased rents which we expect to obtain in following the redevelopment and repositioning of our properties.

Market Conditions

The properties in our portfolio are located in Manhattan and the greater New York metropolitan area, which includes Fairfield County, Connecticut and Westchester County, New York. Positive or negative changes in conditions in these markets, such as business hirings or layoffs or downsizing, industry growth or slowdowns, relocations of businesses, increases or decreases in real estate and other taxes, costs of complying with governmental regulations or changed regulation, can impact our overall performance.

Observatory and Broadcasting Operations

For the year ended December 31, 2015, the Empire State Building Observatory hosted 4.1 million visitors, compared to 4.3 million visitors for the same period in 2014. Observatory revenue for the year ended December 31, 2015 was $112.2 million, a 0.6% increase from $111.5 million for the year ended December 31, 2014. Both full year 2015 and 2014 had 15 bad weather weekend days.

Observatory revenues and admissions are dependent upon the following: (i) the number of tourists (domestic and international) that come to New York City and visit the observatory, as well as any related tourism trends; (ii) the prices per admission that can be charged; (iii) seasonal trends affecting the number of visitors to the observatory; (iv) competition, in particular from the observatories at One World Trade Center and Rockefeller Center; and (v) weather trends.

We license the use of the Empire State Building mast to third party television and radio broadcasters and providers of data communications. We also lease space in the upper floors of the building to such licensees to house their transmission equipment and related facilities. During the year ended December 31, 2015, we derived $20.9 million of revenue and $9.0 million of expense reimbursements from the Empire State Building’s broadcasting licenses and related leases. The broadcasting licenses and related leases generally expire between 2016 and 2023. The business of broadcasting TV and radio signals over the air is in flux, due to deteriorating industry fundamentals and the upcoming Federal Communications Commission spectrum auction, and there is a new competitor in the market at One World Trade Center. We have made preliminary renewal proposals which, if accepted, would yield reduced revenues and higher capital expenditures.

We have renewed and extended our leases with Univision Television Group from their current expirations in 2016 and 2018 to a new expiration in December 2025. Three of our existing broadcast tenants, CBS Broadcasting, NBC Universal Media, and WNET have notified us that they will vacate the Empire State Building at the end of their current lease terms. The non-renewing leases with CBS, NBC and WNET generated approximately $6.3 million in aggregate revenue in 2015, inclusive of expense reimbursements, and their leases expire in 2017 and 2018. Revenue from Univision totaled approximately $2.9 million, inclusive of expense reimbursements in 2015. Effective beginning in January 2016, annual revenue from Univision will adjust to an initial amount of $1.9 million, and is subject to escalations.

Operating Expenses

Our operating expenses generally consist of depreciation and amortization, real estate taxes, ground lease expenses, repairs and maintenance, security, utilities, property-related payroll, insurance and bad debt expense and prior to the Offering and related formation transactions, third-party management fees. Factors that may affect our ability to control these operating costs include: increases in insurance premiums, tax rates, the cost of periodic repair, redevelopment costs and the cost of re-leasing space, the cost of compliance with governmental regulation, including zoning and tax laws, the potential for liability under applicable laws and interest rate levels. Also, as a public company, our annual general and administrative expenses may be meaningfully higher compared to historical expenses due to legal, insurance, accounting and other expenses related to corporate governance, SEC reporting, other compliance matters and the costs of operating as a public company. If our operating costs increase as a result of any of the foregoing factors, our future cash flow and results of operations may be adversely affected.

The expenses of owning and operating a property are not necessarily reduced when circumstances, such as market factors and competition, cause a reduction in income from the property. If revenues drop, we may not be able to reduce our expenses accordingly. Costs associated with real estate investments, such as real estate taxes and maintenance generally, will not be materially reduced even if a property is not fully occupied or other circumstances cause our revenues to decrease. As a result, if revenues decrease in the future, static operating costs may adversely affect our future cash flow and results of operations. If similar economic conditions exist in the future, we may experience future losses.

Cost of Funds and Interest Rates

We expect future changes in interest rates will impact our overall performance. Subject to ESRT maintaining its qualification as a REIT for U.S. federal income tax purposes, we may mitigate the risk of interest rate volatility through the use of hedging instruments, such as interest rate swap agreements and interest rate cap agreements. While we may seek to

manage our exposure to future changes in rates, portions of our overall outstanding debt will likely remain at floating rates. As of December 31, 2015, our floating rate debt represented 18.6% of our indebtedness and 4.7% of total enterprise value. This floating rate debt included $305.0 million of borrowings as of December 31, 2015. Our floating rate debt may increase to the extent we use available borrowing capacity under our loans to fund capital improvements. We continually evaluate our debt maturities, and, based on management’s current assessment, believe we have viable financing and refinancing alternatives that will not materially adversely impact our expected financial results. As of December 31, 2015, excluding principal amortization, we have no debt maturing in 2016 and approximately $355.8 million of debt maturing in 2017.

Competition

The leasing of real estate is highly competitive in Manhattan and the greater New York metropolitan market in which we operate. We compete with numerous acquirers, developers, owners and operators of commercial real estate, many of which own or may seek to acquire or develop properties similar to ours in the same markets in which our properties are located. The principal means of competition are rent charged, location, services provided and the nature and condition of the facility to be leased. In addition, we face competition from other real estate companies including other REITs, private real estate funds, domestic and foreign financial institutions, life insurance companies, pension trusts, partnerships, individual investors and others that may have greater financial resources or access to capital than we do or that are willing to acquire properties in transactions which are more highly leveraged or are less attractive from a financial viewpoint than we are willing to pursue. In addition, competition from observatory and/or broadcasting operations at One World Trade Center and, to a lesser extent, from the observatory at Rockefeller Center and the broadcasting facility at Four Times Square, could have a negative impact on revenues from our observatory and/or broadcasting operations. Adverse impacts on domestic travel and changes in foreign currency exchange rates may also decrease demand in the future, which could have a material adverse effect on our results of operations. If our competitors offer space at rental rates below current market rates, below the rental rates we currently charge our tenants, in better locations within our markets or in higher quality facilities, we may lose potential tenants and may be pressured to reduce our rental rates below those we currently charge in order to retain tenants when our tenants’ leases expire.

Critical Accounting Estimates

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements have been prepared in conformity with GAAP and with the rules and regulations of the SEC represent our assets and liabilities and operating results. The consolidated financial statements include our accounts and our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. For purposes of comparison, certain items shown in the 2013 and 2014 consolidated financial statements have been reclassified to conform to the presentation used for 2015.

Our predecessor's financial statements include all the accounts and operations of our predecessor. The real estate entities included in the accompanying financial statements have been combined on the basis that, for the periods presented, such entities were under common control, common management and common ownership of the sponsors. Equity interests in the combining entities that were not controlled by the sponsors are shown as investments in non-controlled entities. We acquired these interests as a result of the formation transactions.

We consolidate entities in which we have a controlling financial interest. In determining whether we have a controlling financial interest in a partially owned entity and the requirement to consolidate the accounts of that entity, we consider factors such as ownership interest, board representation, management representation, authority to make decisions, and contractual and substantive participating rights of the partners/members as well as whether the entity is a variable interest entity (“VIE”) and we are the primary beneficiary. The primary beneficiary of a VIE is the entity that has (i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE. The primary beneficiary is required to consolidate the VIE. We had no VIEs as of December 31, 2015 and 2014.

We will assess the accounting treatment for each investment we may have in the future. This assessment will include a review of each entity’s organizational agreement to determine which party has what rights and whether those rights are protective or participating. For all VIEs, we will review such agreements in order to determine which party has the power to direct the activities that most significantly impact the entity’s economic performance and benefit. In situations where we or our partner could approve, among other things, the annual budget, or leases that cover more than a nominal amount of space relative to the total rentable space at each property, we would not consolidate the investment as we consider these to be substantive participation rights that result in shared power of the activities that would most significantly impact the performance and benefit of such joint venture investment.

A non-controlling interest in a consolidated subsidiary is defined as the portion of the equity (net assets) in a subsidiary not attributable, directly or indirectly, to a parent. Non-controlling interests are required to be presented as a separate component of equity in the consolidated balance sheets and in the consolidated statements of operations by requiring earnings and other comprehensive income to be attributed to controlling and non-controlling interests. As the financial statements of our predecessor have been prepared on a combined basis, there is no non-controlling interest for our predecessor for the period presented.

Construction Revenue

Revenues from construction contracts are recognized under the percentage-of completion method. Under this method, progress towards completion is recognized according to the ratio of incurred costs to estimated total costs. This method is used because management considers the “cost-to-cost” method the most appropriate in the circumstances.

Contract costs include all direct material, direct labor and other direct costs and an allocation of certain overhead related to contract performance. General and administrative costs are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions and estimated profitability, including those arising from settlements, may result in revisions to costs and income and are recognized in the period in which the revisions are determined.

Goodwill

Goodwill is tested annually for impairment and is tested for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount, including goodwill, exceeds the reporting unit’s fair value and the implied fair value of goodwill is less than the carrying amount of that goodwill. Non-amortizing intangible assets, such as trade names and trademarks, are subject to an annual impairment test based on fair value and amortizing intangible assets are tested whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Income Taxes

We are generally not subject to federal and state income taxes as our taxable income or loss is reportable by our partners. Accordingly, no provision has been made for federal and state income taxes. ESRT elected, together with ESRT Observatory TRS, L.L.C., our subsidiary which holds our observatory operations, to treat ESRT Observatory TRS, L.L.C. as a TRS, and ESRT has elected, together with ESRT Holdings TRS, L.L.C., our subsidiary that holds our third party management, construction (through cessation of our construction business in the first quarter of 2015), restaurant, cafeteria, health clubs and certain cleaning operations, to treat ESRT Holdings TRS, L.L.C. as a TRS. TRSs may participate in non-real estate activities and/or perform non-customary services for tenants and their operations are generally subject to regular corporate income taxes. Each of our TRSs account for their income taxes in accordance with GAAP, which includes an estimate of the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our financial statements or tax returns. The calculation of the TRS's tax provisions may require interpreting tax laws and regulations and could result in the use of judgments or estimates which could cause its recorded tax liability to differ from the actual amount due. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The TRSs periodically assess the realizability of deferred tax assets and the adequacy of deferred tax liabilities, including the results of local, state, or federal statutory tax audits or estimates and judgments used.

We apply provisions for measuring and recognizing tax benefits associated with uncertain income tax positions. Penalties and interest, if incurred, would be recorded as a component of income tax expense. As of December 31, 2015 and 2014, we do not have a liability for uncertain tax positions. As of December 31, 2015, the tax years ended December 31, 2012 through December 31, 2015 remain open for an audit by the Internal Revenue Service, state or local authorities.

During the periods presented, the entities included in our predecessor's consolidated financial statements are treated as partnerships or S corporations for U.S. federal and state income tax purposes and, accordingly, are not subject to entity-level tax. Rather, each entity’s taxable income or loss is allocated to its owners. Therefore, no provision or liability for U.S. federal or state income taxes has been included in the accompanying consolidated financial statements for those periods.

Two of the limited liability companies in our Predecessor had non-real estate income subject to New York City unincorporated business tax (“NYCUBT”). In 2013, one of these entities generated a loss for NYCUBT purposes while the other entity generated income. No provision or liability for U.S. federal, state, or local income taxes has been included in our Predecessor's consolidated financial statements as 2013 taxable income as referred to above was fully offset by a NYCUBT

net operating loss carry forward from previous years. As a result of the consolidation and concurrent liquidation of the entities that had previously been subject to the NYCUBT, the NYCUBT net operating loss carryforward of $13.4 million at October 6, 2013 can no longer be used.

Share-Based Compensation

Share-based compensation is measured at the fair value of the award on the date of grant and recognized as an expense on a straight-line basis over the vesting period. The determination of fair value of these awards is subjective and involves significant estimates and assumptions including expected volatility of ESRT stock, expected dividend yield, expected term, and assumptions of whether these awards will achieve parity with other operating partnership units or achieve performance thresholds. We believe that the assumptions and estimates utilized are appropriate based on the information available to management at the time of grant.

Segment Reporting

We have identified two reportable segments: (1) Real Estate and (2) Observatory. Our real estate segment includes all activities related to the ownership, management, operation, acquisition, repositioning and disposition of our real estate assets. Our observatory segment operates the 86th and 102nd floor observatories at the Empire State Building. These two lines of businesses are managed separately because each business requires different support infrastructures, provides different services and has dissimilar economic characteristics such as investments needed, stream of revenues and different marketing strategies. We account for intersegment sales and transfers as if the sales or transfers were to third parties, that is, at current market prices. We include our construction operation in "Other" and includes all activities related to providing construction services to tenants and to other entities within and outside our company. As of March 27, 2015, we no longer solicited new business for our construction management business. We completed all projects that were in progress.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our future income, cash flows and fair values relevant to financial instruments are dependent upon prevalent market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. One of the principal market risks facing us is interest rate risk on our floating rate indebtedness. As of December 31, 2015, our floating rate debt represented 4.7% of our total enterprise value. This floating rate debt consists of $305.0 million of borrowings under the unsecured term loan and revolving credit facilities.

Subject to maintaining ESRT's qualification as a REIT for U.S. federal income tax purposes, we may mitigate the risk of interest rate volatility through the use of hedging instruments, such as interest rate swap agreements and interest rate cap agreements. Our primary objectives when undertaking hedging transactions and derivative positions will be to reduce our floating rate exposure and to fix a portion of the interest rate for anticipated financing and refinancing transactions. This in turn will reduce the risk that the variability of cash flows will impose on floating rate debt. However, we can provide no assurances that our efforts to manage interest rate volatility will successfully mitigate the risks of such volatility on our portfolio. We are not subject to foreign currency risk.

We are exposed to interest rate changes primarily through unsecured term and credit facilities. Our objectives with respect to interest rate risk are to limit the impact of interest rate changes on operations and cash flows, and to lower our overall borrowing costs. To achieve these objectives, we may borrow at fixed rates and may enter into derivative financial instruments such as interest rate swaps or caps in order to mitigate our interest rate risk on a related floating rate financial instrument. We do not enter into derivative or interest rate transactions for speculative purposes.

During 2015, we entered into three interest rate LIBOR swaps with effective dates of July 5, 2017 and August 31, 2017 and an aggregate notional value of $465.0 million, which fixes interest rates at 2.1485% and 2.5050%, and mature between August 24, 2022 and July 5, 2027.

As of December 31, 2015, we had total outstanding floating rate debt obligations of $305.0 million. Based on our variable balances, interest expense would have increased by approximately $3.0 million for the year ended December 31, 2015, if short-term interest rates had been 1% higher. As of December 31, 2015, the weighted average interest rate on the $1.3 billion of fixed-rate indebtedness outstanding was 4.61% per annum, each with maturities at various dates through March 27, 2030.

As of December 31, 2015, the fair value of our outstanding debt was approximately $1.7 billion which was approximately $20.8 million more than the historical book value as of such date. Interest risk amounts were determined by considering the impact of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of

any change in overall economic activity that could occur in that environment. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) that are designed to ensure that information required to be disclosed in our reports under the Exchange Act is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and regulations and that such information is accumulated and communicated to management, including ESRT's Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As of December 31, 2015, the end of the period covered by this Report, we carried out an evaluation, under the supervision and with the participation of ESRT management, including ESRT's Chief Executive Officer and Chief Financial Officer, regarding the effectiveness of our disclosure controls and procedures at the end of the period covered by this Report. Based on the foregoing, ESRT's Chief Executive Officer and Chief Financial Officer concluded, as of that time, that our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in reports filed or submitted under the Exchange Act (i) is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) is accumulated and communicated to our management, including ESRT's Chief Executive Officer and Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

No significant changes to our internal control over financial reporting were identified in connection with the evaluation referenced above that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

(a) Management's Report on Internal Control over Financial Reporting

Management of Empire State Realty OP, L.P. is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in the Securities Exchange Act of 1934 Rule 13(a)-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2015 as required by the Securities Exchange Act of 1934 Rule 13(a)-15(c). In making this assessment, we used the criteria set forth in the framework in Internal Control–Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the "COSO criteria"). Based on our evaluation under the COSO criteria, our management concluded that our internal control over financial reporting was effective as of December 31, 2015 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.

Ernst & Young LLP, an independent registered public accounting firm that audited our Financial Statements included in this Annual Report, has issued an attestation report on our internal control over financial reporting as of December 31, 2015, which appears in paragraph (b) of this Item 9A.

(b) Attestation report of the independent registered public accounting firm

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Empire State Realty OP, L.P.

We have audited Empire State OP, L.P.’s (the “Operating Partnership”) internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). The Operating Partnership’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Operating Partnership’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Empire State Realty OP, L.P. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Empire State Realty OP, L.P. as of December 31, 2015 (Successor) and 2014 (Successor), and the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity/owners’ equity/(deficit) (Predecessor) and cash flows for the years ended December 31, 2015 (Successor) and December 31, 2014 (Successor), for the period from October 7, 2013 through December 31, 2013 (Successor) and for the period from January 1, 2013 to October 6, 2013 (Predecessor) of Empire State Realty OP, L.P. and our report dated February 26, 2016 expressed an unqualified opinion thereon.

(the Operating Partnership or Successor) as of December 31, 2015 and 2014, and the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity/owners’ equity/(deficit)(Predecessor) and cash flows for the years ended December 31, 2015 (Successor) and December 31, 2014 (Successor), for the period from October 7, 2013 through December 31, 2013 (Successor) and for the period from January 1, 2013 to October 6, 2013 (Predecessor). Our audits also included the financial statement schedules listed in the Index at Item 15. These financial statements and schedules are the responsibility of the Operating Partnership's management. Our responsibility is to express an opinion on these financial statements and schedules based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Empire State Realty OP, L.P. at December 31, 2015 and 2014, and the consolidated results of its operations and its cash flows for the years ended December 31, 2015 (Successor) and December 31, 2014 (Successor), for the period from October 7, 2013 through December 31, 2013 (Successor) and for the period from January 1, 2013 to October 6, 2013 (Predecessor) in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedules, when considered in relation to the basic financial statements taken as a whole, present fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Empire State Realty OP, L.P.’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 26, 2016 expressed an unqualified opinion thereon.

Notes to Consolidated Financial Statements

1. Description of Business and Organization

As used in these consolidated financial statements, unless the context otherwise requires, “we,” “us,” "our," and the "company,” mean the predecessor (as defined below) for the periods presented and Empire State Realty OP, L.P. and its consolidated subsidiaries upon the consummation of Empire State Realty Trust Inc.'s initial public offering of Class A common stock and the formation transactions defined below.

Empire State Realty OP, L.P. is the entity through which Empire State Realty Trust, Inc. ("ESRT"), a self-administered and self-managed real estate investment trust, or REIT, conducts all of its business and owns (either directly or through subsidiaries) substantially all of its assets. We own, manage, operate, acquire and reposition office and retail properties in Manhattan and the greater New York metropolitan area. Empire State Realty Trust, Inc.'s Class A common stock, par value $0.01 per share, is listed on the New York Stock Exchange under the symbol "ESRT."

We were organized as a Delaware limited partnership on November 28, 2011. We did not have any assets other than cash and did not have any meaningful operating activity until the consummation of the Offering and the related acquisition of our predecessor and certain non-controlled entities controlled by our predecessor on October 7, 2013 as part of the formation transactions. Our operations commenced upon completion of the Offering and related formation transactions on October 7, 2013. ESRT as the sole general partner in our company, has responsibility and discretion in the management and control in our company, and our limited partners, in such capacity, have no authority to transact business for, or participate in the management activities of our company. As of December 31, 2015, ESRT owned approximately 44.9% of our operating partnership units.

As of December 31, 2015, our total portfolio contained 10.1 million rentable square feet of office and retail space. We owned 14 office properties (including three long-term ground leasehold interest) encompassing approximately 9.3 million rentable square feet of office space. Nine of these properties are located in the midtown Manhattan market and encompass in the aggregate approximately 7.5 million rentable square feet of office space, including the Empire State Building. Our Manhattan office properties also contain an aggregate of 518,792 rentable square feet of premier retail space on their ground floor and/or lower levels. Our remaining five office properties are located in Fairfield County, Connecticut and Westchester County, New York, encompassing in the aggregate approximately 1.9 million rentable square feet. The majority of square footage for these five properties is located in densely populated metropolitan communities with immediate access to mass transportation. Additionally, we have entitled land at the Stamford Transportation Center in Stamford, Connecticut, adjacent to one of our office properties, that will support the development of an approximately 380,000 rentable square foot office building and garage, which we refer to herein as Metro Tower. As of December 31, 2015, our portfolio also included four standalone retail properties located in Manhattan and two standalone retail properties located in the city center of Westport, Connecticut, encompassing 204,452 rentable square feet in the aggregate.

We have two entities that elected, together with ESRT, to be treated as taxable REIT subsidiaries, or TRSs, of ESRT. The TRSs, through several wholly-owned limited liability companies, conduct third-party services businesses, which include the Empire State Building Observatory, cleaning services, cafeteria, restaurant and fitness center, property management and leasing, construction, and property maintenance.

We entered into a series of formation transactions (the “formation transactions”), pursuant to which we acquired, substantially currently with the completion of the Offering through a series of contributions and merger transactions, our portfolio of real estate assets that comprise our portfolio, the ownership interests in the certain management entities of our predecessor and one development parcel.

For all periods prior to the completion of the Offering and formation transactions, our predecessor results of operations contain unconsolidated results for certain non-controlled entities (as defined below) that owned interests in the Empire State Building, 1350 Broadway, 1333 Broadway, and 501 Seventh Avenue, which were accounted for by our predecessor under the equity method of accounting and make up a significant portion of our company subsequent to the completion of the Offering and formation transactions. Our results of operations for the period January 1, 2013 to October 6, 2013 reflect the financial condition and results of operations of our predecessor. Our financial condition as of December 31, 2015 and 2014 and results of operations for the period October 7, 2013 to December 31, 2013 and the years ended December 31, 2014 and 2015 reflect the financial condition and results of operations of our predecessor consolidated with the non-controlling interests in those four properties we acquired at the time of the Offering and formation transactions.

F-8

The Predecessor

Our predecessor is not a legal entity but rather a combination of (i) controlling interests in (a) 16 office and retail properties, (b) one development parcel, and (c) certain management companies, which were owned by certain entities that Anthony E. Malkin and Peter L. Malkin, as sponsors, owned interests in and controlled, which we collectively refer to as the controlled entities, and (ii) non-controlling interests in four office properties (which include two of the 16 properties set forth in (i) above), held through entities which we collectively refer to as the non-controlled entities, and are presented as uncombined entities in our combined financial statements. Specifically, the term “our predecessor” means (i) Malkin Holdings LLC, a New York limited liability company that acted as the supervisor of, and performed various asset management services and routine administration with respect to, certain of the existing entities, which we refer to as “the supervisor;” (ii) the limited liability companies or limited partnerships that previously (a) owned, directly or indirectly and either through a fee interest or a long-term leasehold in the underlying land, and/or (b) operated, directly or indirectly and through a fee interest, an operating lease, an operating sublease or an operating sub-sublease, the 18 office and retail properties (which include non-controlling interests in four office properties for which Malkin Holdings LLC acted as the supervisor but that are not consolidated into our predecessor for accounting purposes) and entitled land that will support the development of an approximately 380,000 rentable square foot office building and garage that we own after the formation transactions, which we refer to as the “existing entities;” (iii) Malkin Properties, L.L.C., a New York limited liability company that served as the manager and leasing agent for certain of the existing entities in Manhattan, which we refer to as “Malkin Properties;” (iv) Malkin Properties of New York, L.L.C., a New York limited liability company that served as the manager and leasing agent for certain of the existing entities in Westchester County, New York, which we refer to as “Malkin Properties NY;” (v) Malkin Properties of Connecticut, Inc., a Connecticut corporation that served as the manager and leasing agent for certain of the existing entities in the State of Connecticut, which we refer to as “Malkin Properties CT;” and (vi) Malkin Construction Corp., a Connecticut corporation that is a general contractor and provided services to certain of the existing entities and third parties (including certain tenants at the properties in our portfolio), which we refer to as “Malkin Construction.” The term “the predecessor’s management companies” refers to the supervisor, Malkin Properties, Malkin Properties NY, Malkin Properties CT and Malkin Construction, collectively. Our predecessor accounted for its investment in the non-controlled entities under the equity method of accounting.

On September 28, 2012, a Stipulation of Settlement resolving the original class actions was entered into. The terms of the settlement include, amongst other things, a payment of $55.0 million, with a minimum of 80% in cash and a maximum of 20% in freely-tradable shares of ESRT common stock and/or operating partnership units. As the payment is to be fully made by the principal owners of certain predecessor entities, $55.0 million was recorded as settlement expense in our predecessor's statement of operations, with a corresponding $55.0 million capital contribution to our predecessor at that time. Substantially all of the fund has been distributed, but a small amount remains outstanding.

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and with the rules and regulations of the Securities and Exchange Commission (the "SEC") represent our assets and liabilities and operating results. The consolidated financial statements include our accounts and our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

Our predecessor's consolidated financial statements include all the accounts and operations of our predecessor. The real estate entities included in the accompanying consolidated financial statements have been combined on the basis that, for the periods presented, such entities were under common control, common management and common ownership of the Sponsors. Equity interests in the combining entities that were not controlled by the sponsors are shown as investments in non-controlled entities. We acquired these interests as a result of the formation transactions.

F-10

Accounting Estimates

The preparation of the consolidated financial statements in accordance with GAAP requires management to use estimates and assumptions that in certain circumstances affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses. Significant items subject to such estimates and assumptions include allocation of the purchase price of acquired real estate properties among tangible and intangible assets, determination of the useful life of real estate properties and other long-lived assets, valuation and impairment analysis of commercial real estate properties and other long-lived assets, estimate of percentage of completion on construction contracts, valuation of the allowance for doubtful accounts, and valuation of senior unsecured notes and equity based compensation. These estimates are prepared using management’s best judgment, after considering past, current, and expected events and economic conditions. Actual results could differ from those estimates.

Revenue Recognition

Rental Revenue

Rental revenue includes base rents that each tenant pays in accordance with the terms of its respective lease and is reported on a straight-line basis over the non-cancellable term of the lease which includes the effects of rent steps and rent abatements under the leases. We commence rental revenue recognition when the tenant takes possession of the leased space or controls the physical use of the leased space and the leased space is substantially ready for its intended use. We account for all of our leases as operating leases. Deferred rent receivables, including free rental periods and leasing arrangements allowing for increased base rent payments, are accounted for in a manner that provides an even amount of fixed lease revenues over the respective non-cancellable lease terms. Differences between rental income recognized and amounts due under the respective lease agreements are recognized as an increase or decrease to deferred rents receivable.

The timing of rental revenue recognition is impacted by the ownership of tenant improvements and allowances. When we are the owner of the tenant improvements, revenue recognition commences after both the improvements are completed and the tenant takes possession or control of the space. In contrast, if we determine that the tenant allowances we are funding are lease incentives, then we commence revenue recognition when possession or control of the space is turned over to the tenant. Tenant improvement ownership is determined based on various factors including, but not limited to, whether the lease stipulates how and on what a tenant improvement allowance may be spent, whether the tenant or landlord retains legal title to the improvements at the end of the lease term, whether the tenant improvements are unique to the tenant or general-purpose in nature, and whether the tenant improvements are expected to have any residual value at the end of the lease.

In addition to base rent, our tenants also generally will pay their pro rata share of increases in real estate taxes and operating expenses for the building over a base year. In some leases, in lieu of paying additional rent based upon increases in building operating expenses, the tenant will pay additional rent based upon increases in an index such as the Consumer Price Index over the index value in effect during a base year, or contain fixed percentage increases over the base rent to cover escalations.

We will recognize rental revenue of acquired in-place above- and below-market leases at their fair values over the terms of the respective leases, including, for below-market leases, fixed option renewal periods, if any.

Lease cancellation fees are recognized when the fees are determinable, tenant vacancy has occurred, collectability is reasonably assured, we have no continuing obligation to provide services to such former tenants and the payment is not subject to any conditions that must be met or waived. Total lease cancellation fees for the years ended December 31, 2015, 2014, and 2013 were $2.0 million, $6.1 million, and $1.6 million, respectively. Such fees are included in other income and fees in our consolidated statements of operations.

Observatory Revenue

F-11

Revenues from the sale of Observatory tickets are recognized upon admission or ticket expirations. Deferred income related to unused and unexpired tickets as of December 31, 2015 and 2014 was $5.1 million and $4.5 million, respectively.

Construction Revenue

Gains on Sale of Real Estate

We record a gain on sale of real estate when title is conveyed to the buyer and we have no substantial economic involvement with the property. 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.

Third-Party Management, Leasing and Other Fees

We earn revenue arising from contractual agreements with related party entities for asset and property management services. This revenue is recognized as the related services are performed under the respective agreements in place.

Advertising and Marketing Costs

Advertising and marketing costs are expensed as incurred. The expense for the years ended December 31, 2015, 2014, and 2013 was $8.7 million, $10.0 million and $4.2 million, respectively, and is included within operating expenses in our consolidated statements of operations.

Offering Costs and Formation Transaction Expenses

In connection with the Offering and formation transactions, we incurred incremental accounting fees, legal fees and other professional fees. Approximately $33.5 million was previously deferred and recorded as a reduction of proceeds of the Offering. Certain costs associated with the Offering and formation transactions not directly attributable to the solicitation of consents of investors in the existing entities and the Offering, but rather related to structuring the formation transactions, are expensed as incurred.

Real Estate Properties and Related Intangible Assets

Land and buildings and improvements are recorded at cost less accumulated depreciation and amortization. The recorded cost includes cost of acquisitions, development and construction and tenant allowances and improvements. Expenditures for ordinary repairs and maintenance are charged to operations as incurred. Significant replacements and betterments which improve or extend the life of the asset are capitalized. Tenant improvements which improve or extend the life of the asset are capitalized. If a tenant vacates its space prior to the contractual termination of its lease, the unamortized balance of any tenant improvements are written off if they are replaced or have no future value. For developed properties, direct and indirect costs that clearly relate to projects under development are capitalized. Costs include construction costs, professional services such as architectural and legal costs, capitalized interest and direct payroll costs. We begin capitalization when the project is probable. Capitalization of interest ceases when the property is ready for its intended use, which is generally near the date that a certificate of occupancy is obtained.

Depreciation and amortization are computed using the straight-line method for financial reporting purposes. Buildings and improvements are depreciated over the shorter of 39 years, the useful life, or the remaining term of any leasehold interest. Tenant improvement costs, which are included in building and improvements in the consolidated balance sheets, are depreciated over the shorter of (i) the related remaining lease term or (ii) the life of the improvement. Corporate equipment, which is included in “Other assets,” is depreciated over three to seven years.

F-12

Acquisitions of properties are accounted for utilizing the acquisition method and accordingly the purchase cost is allocated to tangible and intangible assets and liabilities based on their fair values. The fair value of tangible assets acquired is determined by valuing the property as if it were vacant, applying methods similar to those used by independent appraisers of income-producing property. The resulting value is then allocated to land, buildings and improvements, and tenant improvements based on our determination of the fair value of these assets. The assumptions used in the allocation of fair values to assets acquired are based on our best estimates at the time of evaluation.

Fair value is assigned to above-market and below-market leases based on the difference between (a) the contractual amounts to be paid by the tenant based on the existing lease and (b) our estimate of current market lease rates for the corresponding in-place leases, over the remaining terms of the in-place leases. Capitalized above-market lease amounts are amortized as a decrease to rental revenue over the remaining terms of the respective leases. Capitalized below-market lease amounts are amortized as an increase to rental revenue over the remaining terms of the respective leases. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off.

The aggregate value of other acquired intangible assets consists of acquired ground leases and acquired in-place leases and tenant relationships. The fair value allocated to acquired in-place leases consists of a variety of components including, but not necessarily limited to: (a) the value associated with avoiding the cost of originating the acquired in-place leases (i.e. the market cost to execute a lease, including leasing commissions and legal fees, if any); (b) the value associated with lost revenue related to tenant reimbursable operating costs estimated to be incurred during the assumed lease-up period (i.e. real estate taxes, insurance and other operating expenses); (c) the value associated with lost rental revenue from existing leases during the assumed lease-up period; and (d) the value associated with any other inducements to secure a tenant lease.

We assess the potential for impairment of our long-lived assets, including real estate properties, annually or whenever events occur or a change in circumstances indicate that the recorded value might not be fully recoverable. We determine whether impairment in value has occurred by comparing the estimated future undiscounted cash flows expected from the use and eventual disposition of the asset to its carrying value. If the undiscounted cash flows do not exceed the carrying value, the real estate is adjusted to fair value and an impairment loss is recognized. Assets held for sale are recorded at the lower of cost or fair value less costs to sell. We do not believe that the value of any of our properties and intangible assets were impaired during the years ended December 31, 2015, 2014 and 2013.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand, demand deposits with financial institutions and short-term liquid investments with original maturities of three months or less when purchased. The majority of our cash and cash equivalents are held at major commercial banks which may at times exceed the Federal Deposit Insurance Corporation limit. To date, we have not experienced any losses on our invested cash.

Restricted Cash

Restricted cash consists of amounts held for tenants in accordance with lease agreements such as security deposits and amounts held by lenders and/or escrow agents to provide for future real estate tax expenditures and insurance expenditures, tenant vacancy related costs, debt service obligations.

Tenant and Other Receivables

Tenant and other accounts receivable, other than deferred rent receivable, are expected to be collected within one year.

Allowance for Doubtful Accounts

We maintain an allowance against tenant and other receivables and deferred rents receivables for future potential tenant credit losses. The credit assessment is based on the estimated accrued rental revenue that is recoverable over the term of the respective lease. The computation of this allowance is based on the tenants’ payment history and current credit status. If our estimate of collectability differs from the cash received, then the timing and amount of our reported revenue could be impacted. Bad debt expense is included in operating expenses on our consolidated statements of operations and includes the impact of changes in the allowance for doubtful accounts on our consolidated balance sheets.

Deferred Lease Costs

F-13

Deferred lease costs consist of fees and direct costs incurred to initiate and renew leases, are amortized on a straight-line basis over the related lease term and the expense is included in depreciation and amortization in our consolidated statements of operations. Upon the early termination of a lease, unamortized deferred leasing costs are charged to expense.

Deferred Financing Costs

Fees and costs incurred to obtain long-term financing have been deferred and are being amortized as a component of interest expense in our consolidated statements of operations over the life of the respective long-term financing on the straight-line method which approximates the effective interest method. Unamortized deferred financing costs are expensed when the associated debt is refinanced or repaid before maturity. Costs incurred in seeking debt, which do not close, are expensed in the period in which it is determined that the financing will not close.

Equity Method Investments

We account for investments under the equity method of accounting where we do not have control but have the ability to exercise significant influence. Under this method, investments are recorded at cost, and the investment accounts are adjusted for our share of the entities’ income or loss and for distributions and contributions. Equity income (loss) is allocated based on the portion of the ownership interest that is controlled by us. The agreements may designate different percentage allocations among investors for profits and losses; however, our recognition of the entity’s income or loss generally follows the entity’s distribution priorities, which may change upon the achievement of certain investment return thresholds.

To the extent that we contributed assets to an entity, our investment in the entity is recorded at cost basis in the assets that were contributed to the entity. Upon contributing assets to an entity, we make a judgment as to whether the economic substance of the transaction is a sale. If so, gain or loss is recognized on the portion of the asset to which the other partners in the entity obtain an interest.

To the extent that the carrying amount of these investments on our combined balance sheets is different than the basis reflected at the entity level, the basis difference would be amortized over the life of the related asset and included in our share of equity in net income of the entity.

On a periodic basis, we assess whether there are any indicators that the carrying value of our investments in entities may be impaired on an other than temporary basis. An investment is impaired only if management’s estimate of the fair value of the investment is less than the carrying value of the investment on an other than temporary basis. To the extent impairment has occurred, the loss shall be measured as the excess of the carrying value of the investment over the fair value of the investment. None of our predecessor's investments are other than temporarily impaired.

Our predecessor recognized incentive income in the form of overage fees from certain uncombined entities (which include non-controlled and other properties not included in our predecessor) as income to the extent it has been earned and not subject to a clawback feature.

If our predecessor's share of distributions and net losses exceeds our investments for certain of the equity method investments and if our predecessor remained liable for future obligations of the entity or was otherwise committed to provide future additional financial support, the investment balances would have been presented in the accompanying combined balance sheets as liabilities. The effects of material intercompany transactions with these equity method investments are eliminated. None of the entity debt is recourse to us.

As of December 31, 2015 and 2014, we had no equity method investments.

Fair Value

F-14

Fair value is a market-based measurement, not an entity-specific measurement, and should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, the Financial Accounting Standards Board ("FASB") guidance establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within levels one and two of the hierarchy) and the reporting entity's own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

We use the following methods and assumptions in estimating fair value disclosures for financial instruments.

For cash and cash equivalents, restricted cash, tenant and other receivables, prepaid expenses and other assets, deferred revenue, tenant security deposits, accounts payable and accrued expenses in our consolidated balance sheets approximate their fair value due to the short term maturity of these instruments.

The fair value of derivative instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. Although the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by ourselves and our counterparties. The impact of such credit valuation adjustments, determined based on the fair value of each individual contract, was not significant to the overall valuation. As a result, all of our derivatives were classified as Level 2 of the fair value hierarchy.

The fair value of our mortgage notes payable, term loan and credit facility, and senior unsecured notes which are determined using Level 3 inputs, are estimated by discounting the future cash flows using current interest rates at which similar borrowings could be made to us.

The methodologies used for valuing financial instruments have been categorized into three broad levels as follows:

Level 1 - Quoted prices in active markets for identical instruments.

Level 2 - Valuations based principally on other observable market parameters, including:


•	Quoted prices in active markets for similar instruments;


•	Quoted prices in less active or inactive markets for identical or similar instruments;


•	Other observable inputs (such as risk free interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates); and


•	Market corroborated inputs (derived principally from or corroborated by observable market data).

Level 3 - Valuations based significantly on unobservable inputs, including:


•	Valuations based on third-party indications (broker quotes or counterparty quotes) which were, in turn, based significantly on unobservable inputs or were otherwise not supportable as Level 3 valuations; and


•	Valuations based on internal models with significant unobservable inputs.

These levels form a hierarchy. We follow this hierarchy for our financial instruments measured or disclosed at fair value on a recurring and nonrecurring basis and other required fair value disclosures. The classifications are based on the lowest level of input that is significant to the fair value measurement.

Derivative Instruments

We are exposed to the effect of interest rate changes and manage these risks by following policies and procedures including the use of derivatives. To manage exposure to interest rates, derivatives are used primarily to fix the rate on debt based on floating-rate indices. We record all derivatives on the balance sheet at fair value. We incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. For derivatives that qualify as cash flow hedges, we report the effective portion of changes in the fair value of a derivative designated as a hedge as part of other comprehensive income (loss) and subsequently reclassify the effective portion into income in the period that the hedged item affects income. We account for the ineffective portion of changes in the fair value of a derivative directly in income. Reported net income and equity may increase or decrease

F-15

prospectively, depending on future levels of interest rates and other variables affecting the fair values of derivative instruments and hedged items, but will have no effect on cash flows.

We measure the credit risk of our derivative instruments that are subject to master netting agreements on a net basis by counterparty portfolio.

Income Taxes

We are generally not subject to federal and state income taxes as our taxable income or loss is reportable by our partners. Accordingly, no provision has been made for federal and state income taxes. ESRT has elected, together with ESRT Observatory TRS, L.L.C., our subsidiary which holds our observatory operations, to treat ESRT Observatory TRS, L.L.C. as a TRS. ESRT has elected, together with ESRT Holdings TRS, L.L.C., our subsidiary that holds our third party management, construction (through cessation of our construction business in the first quarter of 2015), restaurant, cafeteria, health clubs and certain cleaning operations, to treat ESRT Holdings TRS, L.L.C. as a TRS. TRSs may participate in non-real estate activities and/or perform non-customary services for tenants and their operations are generally subject to regular corporate income taxes. Our TRSs account for their income taxes in accordance with GAAP, which includes an estimate of the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our financial statements or tax returns. The calculation of the TRSs' tax provisions may require interpreting tax laws and regulations and could result in the use of judgments or estimates which could cause its recorded tax liability to differ from the actual amount due. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The TRSs periodically assess the realizability of deferred tax assets and the adequacy of deferred tax liabilities, including the results of local, state, or federal statutory tax audits or estimates and judgments used.

Two of the limited liability companies in our predecessor had non-real estate income subject to New York City unincorporated business tax (“NYCUBT”). In 2013, one of these entities generated a loss for NYCUBT purposes while the other entity generated income. No provision or liability for U.S. federal, state, or local income taxes has been included in our predecessor's consolidated financial statements as 2013 taxable income referred to above was fully offset by a NYCUBT net operating loss carry forward from previous years.

As a result of the consolidation and concurrent liquidation of the entities that had previously been subject to the NYCUBT, the NYCUBT net operating loss carryforward of $13.4 million at October 6, 2013 can no longer be used.

Share-Based Compensation

Per Unit Data

Basic and diluted earnings per unit are computed based upon the weighted average number of shares outstanding during the respective period.

Segment Reporting

F-16

We have identified two reportable segments: (1) Real Estate and (2) Observatory. Our real estate segment includes all activities related to the ownership, management, operation, acquisition, repositioning and disposition of our real estate assets. Our observatory segment operates the 86th and 102nd floor observatories at the Empire State Building. These two lines of businesses are managed separately because each business requires different support infrastructures, provides different services and has dissimilar economic characteristics such as investments needed, stream of revenues and different marketing strategies. We account for intersegment sales and transfers as if the sales or transfers were to third parties, that is, at current market prices. We include our construction operation in "Other" and it includes all activities related to providing construction services to tenants and to other entities within and outside our company. As of March 27, 2015, we no longer solicited new business for our construction management business. We completed all projects that were in progress.

Reclassification

Certain prior year balances have been reclassified to conform to our current year presentation primarily in order to include acquired lease intangibles, net as part of deferred costs, net, to present ground rent expense and income tax expense accounts separately and to reclassify acquisition expenses from other expenses to operating expenses.

Recently Issued or Adopted Accounting Standards

During January 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Liabilities, which makes targeted improvements to existing generally accepted accounting principles by requiring, among others, i) equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, and ii) public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, iii) separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. ASU No. 2016-01 will take effect for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are evaluating the impact of adopting this new accounting standard on our financial statements.

During September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments, which requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. Previously, adjustments to provisional amounts were applied retrospectively. This update requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU No. 2015-16 will be effective for fiscal years beginning January 1, 2016 and subsequent interim periods. We do not expect the adoption of this new accounting standard to have a material impact on our financial statements.

During June 2015, the FASB issued ASU No. 2015-10, Technical Corrections and Improvements, which contains amendments that represent changes to clarify the FASB Accounting Standards Codification (“Codification”), correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments in ASU No. 2015-10 that require transition guidance are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. All other amendments will be effective upon its issuance. We do not expect the adoption of this new accounting standard to have a material impact on our financial statements.

During April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which amends the requirements for the presentation of debt issuance costs and requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU No. 2015-03 is effective for fiscal years, beginning after December 15, 2015 and interim periods within those fiscal years. ASU No. 2015-03 was amended in August 2015 by ASU No. 2015-15, Interest - Imputation of Interest (Subtopic 835-30) - Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, to add to the Codification SEC staff guidance that the SEC staff will not object to an entity presenting the costs of securing line-of-credit arrangements as an asset, regardless of whether there are any outstanding borrowings. The SEC Observer to the Emerging Issues Task Force announced the staff guidance in response to questions that arose after the FASB issued ASU No. 2015-03. We elected to early adopt ASU 2015-03 as of December 31, 2015, and retrospectively reclassified $13.0 million of debt issuance costs as of December 31, 2014 from

F-17

deferred costs, net to mortgage notes payable, senior unsecured notes, unsecured term loan facility and unsecured revolving credit facility.

During February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810)—Amendments to the Consolidation Analysis, which amends the criteria for determining which entities are considered VIEs, amends the criteria for determining if a service provider possesses a variable interest in a VIE and ends the deferral granted to investment companies for application of the VIE consolidation model. ASU No. 2015-02 is effective for annual periods, and interim periods therein, beginning after December 15, 2015. The standard allows for either a full retrospective or a modified retrospective approach to adoption. We do not expect the adoption of this new accounting standard to have a material impact on our financial statements.

During May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. This new standard will replace all current U.S. GAAP guidance related to revenue recognition and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company 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. This guidance will be effective beginning in 2017 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. We are evaluating the impact of adopting this new accounting standard on our financial statements.

During April 2014, the FASB issued ASU No. 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. ASU No. 2014-08 changes the definition of a discontinued operation to include only those disposals of components of an entity that represent a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. This guidance is effective prospectively for fiscal years beginning after December 15, 2014. The adoption of ASU No. 2014-08 did not have a material impact on our financial statements.

3. Acquisitions

2014 Acquisitions

On July 15, 2014, we acquired the ground and operating lease at 111 West 33rd Street (formerly known as 112 West 34th Street) (and the fee title to 122 West 34th Street) for $423.6 million, consisting of $87.7 million by assumption of existing mortgage debt, $106.9 million in cash and $229.0 million in shares of Class A and Class B common stock and Series PR OP units. In connection with this transaction, we issued 1,217,685 shares of Class A common stock and 77,945 shares of Class B common stock at a share price of $16.65 and 12,457,379 Series PR OP Units at a unit price of $16.65.

On July 15, 2014, we acquired the ground lease at 1400 Broadway for $310.0 million, consisting of $80.0 million by assumption of existing mortgage debt, $79.7 million in cash and $150.3 million in shares of Class A and Class B common stock and Series PR OP units. In connection with this transaction, we issued 1,338,488 shares of Class A common stock and 32,452 shares of Class B common stock at a share price of $16.65 and 7,658,516 Series PR OP Units at a unit price of $16.65.

The following table is an allocation of the purchase price for the assets and liabilities acquired (amounts in thousands):

F-18



Consideration paid:
Cash and issuance of Class A Common Stock, Class B Common Stock, and Series PR OP units	$	565,916
Debt assumed	167,684
Total consideration paid	$	733,600

Net assets acquired:
Land and building and improvements	$	354,429
Acquired below-market ground leases	334,178
Acquired above-market leases	13,088
Acquired in place lease value and deferred leasing costs	88,374
Mortgage notes payable, inclusive of premium	(182,851		)
Acquired below-market leases	(36,553		)
Other liabilities, net of other assets	(4,749		)
Total net assets acquired	$	565,916

2013 Acquisitions

On October 7, 2013, as discussed in Note 1, through the Offering and formation transactions we acquired the assets and liabilities of the four entities in which our predecessor held non-controlling interests. The contribution or acquisition of assets in these entities was accounted for as an acquisition under the acquisition method of accounting and recognized at the estimated fair value of acquired assets and assumed liabilities on the date of such contribution or acquisition. Prior to the acquisition, our predecessor had a 23.75%, 50.0%, 50.0%, and 20.469% non-controlling interest in Empire State Building Company, L.L.C., 1333 Broadway Associates, L.L.C., 1350 Broadway Associates, L.L.C., and 501 Seventh Avenue Associates, L.L.C., respectively.

Upon acquisition, we remeasured the assets and liabilities we acquired from the non-controlled entities at fair value and recorded gains of $214.3 million, which are classified as gain on consolidation of non-controlled entities in the accompanying statement of operations. This gain was calculated based on the difference between the total consideration value of our predecessor’s ownership interests of $302.7 million compared to our predecessor’s historical cost interests of $88.4 million. We determined that the fair values of the assets acquired from and assumed liabilities for 1333 Broadway Associates, L.L.C. and 1350 Broadway Associates, L.L.C. were greater than the consideration granted and we recorded gains of $41.0 million and $32.1 million, respectively, which were classified as gain on consolidation of non-controlled entities in the accompanying statement of operations. There are operating leases between one of our predecessor entities and Empire State Building Company, L.L.C. and 501 Seventh Avenue Associates, L.L.C. Based upon current market rates for similar arrangements, we determined that the current market rent would be less than the pre-existing contractual rent existing at the time of the Offering and formation transactions under the operating leases. Accordingly, upon elimination of the leasehold position and the related liability for the above-market leases, we recorded gains of $35.2 million, which are classified as gain on consolidation of non-controlled entities in the accompanying statement of operations.

F-19

The following table is an allocation of the purchase price for the assets and liabilities acquired in the formation transactions (amounts in thousands).



Consideration paid:
Cash and issuance of Class A Common Stock, Class B Common Stock, and OP units	$	1,047,487
Debt assumed	124,354
Total consideration paid	$	1,171,841

Net assets acquired:
Land	$	91,435
Building and improvements	516,344
Acquired below-market ground lease	62,738
Acquired above-market leases	72,123
Acquired in place lease value and deferred leasing costs	186,415
Goodwill	491,479
Other assets, net of other liabilities	6,061
Mortgage notes payable	(136,226		)
Acquired below-market leases	(134,651		)
Total net assets acquired	$	1,155,718

Gain on the elimination of leasehold positions	$	35,147
Fair values of the assets acquired and assumed liabilities were greater than the consideration granted:
1333 Broadway Associates L.L.C.	40,962
1350 Broadway Associates L.L.C.	32,122
Total	$	108,231

We acquired Empire State Building Company, L.L.C. and 501 Seventh Avenue Associates, L.L.C. for an amount in excess of their net tangible and identified intangible assets and liabilities and as a result we recorded goodwill related to the transaction (see also Note 5). Goodwill was allocated $227.5 million to the observatory operations of the Empire State Building, $250.8 million to Empire State Building Company, L.L.C., and $13.2 million to 501 Seventh Avenue Associates, L.L.C. No amount of goodwill is deductible for tax purposes.

4. Investments in Non-controlled Entities

We had no investment in in non-controlled entities as of December 31, 2015 and 2014.

On October 7, 2013, as part of the Offering and formation transactions, we acquired the assets and liabilities held by the four non-controlled entities (see discussion in Note 3). The investments in non-controlled entities consisted of the following for the period January 1, 2013 through October 6, 2013:



Entity	Property	Nominal % Ownership
Empire State Building Company, L.L.C.	350 Fifth Ave, New York, NY	23.750	%
1333 Broadway Associates, L.L.C.	1333 Broadway, New York, NY	50.000	%
1350 Broadway Associates, L.L.C.	1350 Broadway, New York, NY	50.000	%
501 Seventh Avenue Associates, L.L.C.	501 Seventh Ave, New York, NY	20.469	%

Empire State Building Company, L.L.C. was the operating lessee of the property at 350 Fifth Avenue. The land and fee owner, Empire State Building Associates L.L.C., was a predecessor controlled entity whose operations are included in our predecessor's combined financial statements.

1333 Broadway Associates, L.L.C. owned the fee and leasehold positions at the same address.

1350 Broadway Associates, L.L.C. was the operating lessee of the property at the same address.

F-20

501 Seventh Avenue Associates L.L.C. was the operating lessee of the property at the same address. The fee owner, Seventh Avenue Building Associates L.L.C., was a predecessor controlled entity whose operations are included in our predecessor's combined financial statements.

Our predecessor's share of income from these entities may have exceeded nominal ownership percentages based on the achievement of certain income thresholds as set forth in the relevant partnership agreements.

The following reflects summarized financial information of the non-controlled entities for the period January 1, 2013 through October 6, 2013 (amounts in thousands):

5. Deferred Costs, Acquired Lease Intangibles and Goodwill

Deferred costs, net, consisted of the following at December 31, (amounts in thousands):



	2015			2014
Leasing costs	$	121,864		$	100,653
Acquired in-place lease value and deferred leasing costs	285,902			304,916
Acquired above-market leases	81,680			84,633
	489,446			490,202
Less: accumulated amortization	(178,767		)	(132,740		)
Total deferred costs, net	$	310,679		$	357,462

Amortization expense related to deferred leasing and acquired deferred leasing costs was $25.4 million, $21.9 million, and $10.6 million, for the years ended December 31, 2015, 2014, and 2013, respectively. Amortization expense related to acquired lease intangibles was $37.7 million, $33.7 million and $5.3 million for the years ended December 31, 2015, 2014 and 2013, respectively.

Amortizing acquired intangible assets and liabilities consisted of the following at December 31, (amounts in thousands):



	2015			2014
Acquired below-market ground leases	$	396,916		$	396,916
Less: accumulated amortization	(13,025		)	(5,029		)
Acquired below-market ground leases, net	$	383,891		$	391,887

F-21



	2015			2014
Acquired below-market leases	$	(163,290	)	$	(169,805	)
Less: accumulated amortization	59,119			30,946
Acquired below-market leases, net	$	(104,171	)	$	(138,859	)

Rental revenue related to the amortization of below market leases, net of above market leases was $19.4 million, $14.1 million and $1.9 million for the years ended December 31, 2015, 2014 and 2013, respectively. The remaining weighted-average amortization period as of December 31, 2015 is 26.0 years, 4.9 years, 4.0 years and 4.5 years for below-market ground leases, in-place leases and deferred leasing costs, above-market leases and below-market leases, respectively. We expect to recognize amortization expense and rental revenue from the acquired intangible assets and liabilities as follows (amounts in thousands):



For the year ending:	Future Ground Rent Amortization		Future Amortization Expense		Future Rental Revenue
2016	$	7,831	$	32,756	$	9,283
2017	7,831		25,331		5,658
2018	7,831		19,298		6,338
2019	7,831		16,534		6,552
2020	7,831		13,389		3,453
Thereafter	344,736		64,027		18,643
	$	383,891	$	171,335	$	49,927

As of December 31, 2015, we had goodwill of $491.5 million. In 2013, we acquired the interests in Empire State Building Company, L.L.C. and 501 Seventh Avenue Associates, L.L.C. for an amount in excess of their net tangible and identified intangible assets and liabilities and as a result we recorded goodwill related to the transaction. Goodwill was allocated $227.5 million to the observatory operations of the Empire State Building, $250.8 million to Empire State Building, and $13.2 million to 501 Seventh Avenue.

We performed an annual review of goodwill for impairment and concluded there was no impairment of goodwill. Our methodology to review goodwill impairment, which includes a significant amount of judgment and estimates, provides a reasonable basis to determine whether impairment has occurred. However, many of the factors employed in determining whether or not goodwill is impaired are outside of our control and it is reasonably likely that assumptions and estimates will change in future periods.

6. Debt

Debt consisted of the following as of December 31, 2015 and 2014 (amounts in thousands):

Unsecured Revolving Credit Facility

Concurrently with the entering into the unsecured revolving credit facility, on January 23, 2015, we terminated the secured revolving and term credit facility and wrote off $1.3 million of deferred financing costs. In connection with the termination of the existing facility, all of the guarantors thereunder were released from their guaranty obligations, all liens created thereby were terminated, and all collateral pledged thereunder was released.

The unsecured revolving credit facility is comprised of a revolving credit facility in the maximum original principal amount of $800.0 million. The unsecured revolving credit facility contains an accordion feature that would allow us to increase the maximum aggregate principal amount to $1.25 billion under specified circumstances. As of December 31, 2015, the unsecured revolving credit facility had an outstanding balance of $40.0 million.

Amounts outstanding under the unsecured revolving credit facility will bear interest at a floating rate equal to, at our election, (x) a Eurodollar rate, plus a spread that we expect will range from 0.875% to 1.600% depending upon our leverage ratio and credit rating; or (y) a base rate, plus a spread that we expect will range from 0.000% to 0.600% depending upon our leverage ratio and credit rating. In addition, the unsecured revolving credit facility permits us to borrow at competitive bid rates determined in accordance with the procedures described in the unsecured revolving credit facility. We paid certain customary fees and expense reimbursements.

The initial maturity of the unsecured revolving credit facility is January 2019. We have the option to extend the initial term of the unsecured revolving credit facility for up to two additional 6-month periods, subject to certain conditions, including the payment of an extension fee equal to 0.075% of the then outstanding commitments under the unsecured revolving credit facility.

The unsecured revolving credit facility includes the following financial covenants: (i) maximum leverage ratio of total indebtedness to total asset value of the loan parties and their consolidated subsidiaries will not exceed 60%, (ii) consolidated secured indebtedness will not exceed 40% of total asset value, (iii) tangible net worth will not be less than $745.4 million plus

F-24

75% of net equity proceeds received by us (other than proceeds received within ninety (90) days after the redemption, retirement or repurchase of ownership or equity interests in us up to the amount paid by us in connection with such redemption, retirement or repurchase, where, the net effect is that we shall not have increased our net worth as a result of any such proceeds), (iv) adjusted EBITDA (as defined in the unsecured revolving credit facility) to consolidated fixed charges will not be less than 1.50x, (v) the aggregate net operating income with respect to all unencumbered eligible properties to the portion of interest expense attributable to unsecured indebtedness will not be less than 1.75x, (vi) the ratio of total unsecured indebtedness to unencumbered asset value will not exceed 60%, and (vii) consolidated secured recourse indebtedness will not exceed 10% of total asset value (provided, however, this covenant shall not apply at any time after we achieve a debt ratings from at least two of Moody’s, S&P and Fitch, and such debt ratings are Baa3 or better (in the case of a rating by Moody’s) or BBB- or better (in the case of a rating by S&P or Fitch)).

The unsecured revolving credit facility contains customary covenants, including limitations on liens, investment, debt, fundamental changes, and transactions with affiliates, and will require certain customary financial reports. The unsecured revolving credit facility contains customary events of default (subject in certain cases to specified cure periods), including but not limited to non-payment, breach of covenants, representations or warranties, cross defaults, bankruptcy or other insolvency events, judgments, ERISA events, invalidity of loan documents, loss of real estate investment trust qualification, and occurrence of a change of control (defined in the definitive documentation for the unsecured credit facility).

As of December 31, 2015, we were in compliance with the covenants under the unsecured revolving credit facility.

Secured Revolving and Term Credit Facility

Senior Unsecured Notes

Exchangeable Senior Notes

During August 2014, we issued $250.0 million principal amount of 2.625% Exchangeable Senior Notes (“Senior Notes”) due August 15, 2019. In connection with this offering, we received net proceeds of $246.9 million, after deducting the related underwriting discounts and commissions and issuance costs.

Interest on the Senior Notes will be payable semi-annually in arrears on February 15 and August 15 of each year, beginning February 15, 2015. The Senior Notes are senior unsecured obligations and rank equally in right of payment with all of our other senior unsecured indebtedness and effectively subordinated in right of payment to all of our secured indebtedness (to the extent of the value of the collateral securing such indebtedness) and structurally subordinated to all liabilities and preferred equity of our subsidiaries.

The Senior Notes will mature on August 15, 2019, unless earlier exchanged, redeemed or repurchased. Holders may exchange their Senior Notes at their option at any time prior to the close of business on the business day immediately preceding May 15, 2019 only under the following circumstances: (i) during any calendar quarter beginning after September 30, 2014 (and only during such quarter) if the closing sale price of our Class A common stock is more than 130% of the then current exchange price for at least 20 trading days (whether or not consecutive) in the period of the 30 consecutive trading days ending on the last trading day of the previous calendar quarter; (ii) during the five consecutive business-day period following any five consecutive trading-day period in which the trading price per 1,000 principal amount of the Senior Notes for each trading day during such five consecutive trading-day period in which the trading price per 1,000 principal amount of the Senior Notes for each trading day during such five trading-day period was less than 98% of the closing sale price of our Class A common stock, for each trading day during such five trading-day period multiplied by the then current exchange rate; (iii) if we call any or all of the Senior Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (iv) upon the occurrence of specified corporate transactions (significant consolidation, sale, merger, share exchange, fundamental change, etc.).

On or after May 15, 2019, and on or prior to the second scheduled trading day immediately preceding the maturity date, holders may exchange their notes without regard to the foregoing conditions.

The Senior Notes will be exchangeable into cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at our election. We have asserted it is our intent and ability to settle the principal amount of the

F-25

Senior Notes in cash. The initial exchange rate of Senior Notes is 51.4059 shares per $1,000 principal amount of notes (equivalent to an initial exchange price of approximately $19.45 per share of Class A common stock), subject to adjustment, as described in the related indenture governing the Senior Notes.

Following certain corporate transactions which constitute a make-whole fundamental change (defined in the indenture), we will increase the exchange rate for holders who elect to exchange their Senior Notes in connection with such make whole fundamental change in certain circumstances. Following certain corporate transactions which constitute a fundamental change, holders may require us to repurchase the Senior Notes for cash at a price equal to 100% of the principal amount of the notes to be purchased plus any accrued and unpaid interest to, but excluding, the repurchase date.

We have separately accounted for the liability and equity components of the Senior Notes by bifurcating gross proceeds between the indebtedness, or liability component, and the embedded conversion option, or the equity component. The bifurcation was done by estimating an effective interest rate as of the date of the issuance for similar notes which do not contain an embedded conversion option. This effective interest rate was estimated to be 3.8% and was used to compute the fair value at the time of issuance for the indebtedness of $236.6 million. The gross proceeds from the issuance of the Senior Notes less the initial amount allocated to the indebtedness resulted in a $13.4 million allocation to the embedded conversion option which is included in Equity, net of financing costs, in the consolidated balance sheets as of December 31, 2015 and 2014. The resulting debt discount is being amortized over the five year period in which the Senior Notes are expected to be outstanding (that is, through maturity date) as additional non-cash interest expense. As of December 31, 2015 and 2014, the unamortized discount was $9.7 million and $12.3 million, respectively. The additional non-cash interest expense attributable to the Senior Notes will increase in subsequent reporting periods through the maturity date as the Senior Notes accrete to their par value over the same period.

Underwriting discounts and commissions and issuance costs totaled $3.1 million and were allocated to the indebtedness and the embedded conversion option on a pro-rata basis and accounted for as debt issuance costs and equity issuance costs, respectively. In this connection, $2.9 million attributable to the indebtedness was recorded as part of deferred costs, to be subsequently amortized using the effective interest method as interest expense over the expected term of the Senior Notes, and $0.2 million attributable to the embedded conversion option was recorded as a reduction to Equity in the consolidated balance sheets as of December 31, 2015 and 2014.

For the years ended December 31, 2015 and 2014, total interest expense related to the Senior Notes was $9.9 million and $3.8 million, respectively, consisting of (i) the contractual interest expense of $6.6 million and $2.5 million, respectively, (ii) the additional non-cash interest expense of $2.7 million and $1.1 million, respectively, related to the accretion of the debt discount, and (iii) the amortization of deferred financing costs of $0.6 million and $0.2 million, respectively.

Series A, Series B, and Series C Senior Notes

During March 2015, we issued and sold an aggregate principal amount of $350 million senior unsecured notes consisting of $100 million of 3.93% Series A Senior Notes due 2025, $125 million of 4.09% Series B Senior Notes due 2027, and $125 million of 4.18% Series C Senior Notes due 2030 (together, the “Series A, B and C Senior Notes”). Interest on the Series A, B and C Senior Notes is payable quarterly.

The terms of the Series A, B and C Senior Notes agreement include customary covenants, including limitations on liens, investment, debt, fundamental changes, and transactions with affiliates and will require certain customary financial reports. It also requires compliance with financial ratios consistent with our unsecured revolving credit facility including a maximum leverage ratio, a maximum secured leverage ratio, a minimum amount of tangible net worth, a minimum fixed charge coverage ratio, a minimum unencumbered interest coverage ratio, a maximum unsecured leverage ratio and a maximum amount of secured recourse indebtedness.

The proceeds from the issuance of the Series A, B and C Senior Notes were used to repay outstanding mortgage debt, reduce amounts outstanding under the unsecured revolving credit facility and for other general corporate purposes. As of December 31, 2015, we were in compliance with the covenants under the Series A, B and C Senior Notes.

Senior Unsecured Term Loan Facility

During August 2015, we entered into a senior unsecured term loan facility, which is referred to herein as the “term loan facility” with Wells Fargo Bank, National Association, as administrative agent, Capital One, National Association, as syndication agent, PNC Bank, National Association, as documentation agent, and the lenders from time to time party thereto.

F-26

The term loan facility is in the original principal amount of up to $265.0 million, all of which was borrowed at closing.

Amounts outstanding under the term loan facility bear interest at a floating rate equal to, at our election, (x) a LIBOR rate, plus a spread that ranges from 1.400% to 2.350% depending upon our leverage ratio and credit rating; or (y) a base rate, plus a spread that ranges from 0.400% to 1.350% depending upon our leverage ratio and credit rating. Pursuant to a forward interest rate swap agreement, we effectively fixed LIBOR at 2.1485% for $265.0 million of the term loan facility for the period beginning on August 31, 2017 through maturity. In connection with the closing of the term loan facility, we paid certain customary fees and expense reimbursements.

The term loan facility matures on August 24, 2022. We may prepay loans under the term loan facility at any time, subject to certain notice requirements. To the extent that we prepay all or any portion of a loan on or prior to August 24, 2017, we will pay a prepayment premium equal to (i) if such prepayment occurs on or prior to August 24, 2016, 2.00% of the principal amount so prepaid, and (ii) if such prepayment occurs after August 24, 2016 but on or prior to August 24, 2017, 1.00% of the principal amount so prepaid.

The terms of the term loan facility agreement include customary covenants, including limitations on liens, investment, debt, fundamental changes, and transactions with affiliates and will require certain customary financial reports. The term loan facility requires compliance with financial ratios including a maximum leverage ratio, a maximum secured leverage ratio, a minimum amount of tangible net worth, a minimum fixed charge coverage ratio, a minimum unencumbered interest coverage ratio, a maximum unsecured leverage ratio and a maximum amount of secured recourse indebtedness. It also contains customary events of default (subject in certain cases to specified cure periods). These terms in the term loan facility agreement are consistent with the terms under our unsecured revolving credit facility agreement.

The proceeds from the term loan facility were used to repay borrowings made under the unsecured revolving credit facility. As of December 31, 2015, we were in compliance with the covenants under the term loan facility.

8. Financial Instruments and Fair Values

Derivative Financial Instruments

We use derivative financial instruments primarily to manage interest rate risk and such derivatives are not considered speculative. These derivative instruments are typically in the form of interest rate swap and forward agreements and the primary objective is to minimize interest rate risks associated with investing and financing activities. The counterparties of these arrangements are major financial institutions with which we may also have other financial relationships. We are exposed to credit risk in the event of non-performance by these counterparties; however, we currently do not anticipate that any of the counterparties will fail to meet their obligations.

We have agreements with our derivative counterparties that contain a provision where if we either default or are capable of being declared in default on any of our indebtedness, then we could also be declared in default on our derivative

F-27

obligations. As of December 31, 2015, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $2.0 million. If we had breached any of these provisions at December 31, 2015, we could have been required to settle our obligations under the agreements at their termination value of $2.0 million.

As of December 31, 2015, we have three interest rate LIBOR swaps with an aggregate notional value of $465.0 million. The notional value does not represent exposure to credit, interest rate or market risks. The fair value of these derivative instruments, which is included in accounts payable and accrued expenses on the consolidated balance sheet, amounted to $1.9 million at December 31, 2015. These interest rate swaps have been designated as cash flow hedges and hedge the future cash outflows on our mortgage debt and also on our term loan facility that is subject to a floating interest rate. As of December 31, 2015, these cash flow hedges are deemed effective and an unrealized loss of $1.9 million is reflected in the consolidated statements of comprehensive income (loss). Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on these debt. We estimate that no amount of the current balance held in accumulated other comprehensive loss will be reclassified into interest expense within the next 12 months.

The table below summarizes the terms of agreements and the fair values of our derivative financial instruments as of December 31, 2015 and 2014 (dollar amounts in thousands):



	As of December 31, 2015							December 31, 2015					December 31, 2014
Derivative	Notional Amount		Receive Rate	Pay Rate		Effective Date	Expiration Date	Asset		Liability			Asset		Liability

Fair Valuation

The estimated fair values at December 31, 2015 and 2014 were determined by management, using available market information and appropriate valuation methodologies. Considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts we could realize on disposition of the financial instruments. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

The fair value of derivative instruments, which is classified as Level 2, and measured on a recurring basis, is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

The fair value of borrowings, which is classified as Level 3, is estimated by discounting the contractual cash flows of each debt to their present value using adjusted market interest rates, which is provided by a third-party specialist.

F-28

The following tables summarize the carrying and estimated fair values of our financial instruments as of December 31, 2015 and 2014 (amounts in thousands):

Disclosure about the fair value of financial instruments is based on pertinent information available to us as of December 31, 2015 and 2014. Although we are not aware of any factors that would significantly affect the reasonable fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date and current estimates of fair value may differ significantly from the amounts presented herein.

9. Rental Income

We lease various office spaces to tenants over terms ranging from one to 16 years. Certain leases have renewal options for additional terms. The leases provide for base monthly rentals and reimbursements for real estate taxes, escalations linked to the consumer price index or common area maintenance known as operating expense escalation. Operating expense reimbursements are reflected in our consolidated statements of operations as tenant expense reimbursement.

As of December 31, 2015, we were entitled to the following future contractual minimum lease payments on non-cancellable operating leases to be received which expire on various dates through 2031 (amounts in thousands):



2016	$	423,874
2017	401,147
2018	358,731
2019	325,703
2020	284,462
Thereafter	1,248,224
	$	3,042,141

The above future minimum lease payments exclude tenant recoveries, amortization of deferred rent receivables and the net accretion of above-below-market lease intangibles. Some leases are subject to termination options generally upon payment of a termination fee. The preceding table is prepared assuming such options are not exercised.

10. Commitments and Contingencies

Legal Proceedings

Litigation

F-29

Except as described below, as of December 31, 2015, we were not involved in any material litigation, nor, to our knowledge, was any material litigation threatened against us or our properties, other than routine litigation arising in the ordinary course of business such as disputes with tenants. We believe that the costs and related liabilities, if any, which may result from such actions, will not materially affect our consolidated financial position, operating results or liquidity.

In March 2012, five putative class actions, or the "Original Class Actions," were filed in New York State Supreme Court, New York County by investors in certain of the existing entities (constituting the predecessor and the non-controlled entities) (the "Existing Entities") on March 1, 2012, March 7, 2012, March 12, 2012, March 14, 2012 and March 19, 2012. The plaintiffs asserted claims against our predecessor’s management companies, Anthony E. Malkin, Peter L. Malkin, the estate of Leona M. Helmsley, ESRT and us for breach of fiduciary duty, unjust enrichment and/or aiding and abetting breach of fiduciary duty. They alleged, among other things, that the terms of the consolidation and the process by which it was structured (including the valuation that was employed) are unfair to the investors in the Existing Entities, the consolidation provides excessive benefits to Malkin Holdings LLC (now our subsidiary) and its affiliates and the then-draft prospectus/consent solicitation with respect to the consolidation filed with the SEC failed to make adequate disclosure to permit a fully-informed decision about the consolidation. The complaints sought money damages and injunctive relief preventing the consolidation. The Original Class Actions were consolidated and co-lead plaintiffs’ counsel were appointed by the New York State Supreme Court by order dated June 26, 2012. Further, an underlying premise of the Original Class Actions, as noted in discussions among plaintiffs' counsel and defendants' counsel, was that the consolidation had been structured in such a manner that would cause investors in Empire State Building Associates L.L.C., 60 East 42nd St. Associates L.L.C. and 250 West 57th St. Associates L.L.C. (the “subject LLCs”) immediately to incur substantial tax liabilities.

The parties entered into a Stipulation of Settlement dated September 28, 2012, resolving the Original Class Actions. The Stipulation of Settlement recites that the consolidation was approved by overwhelming consent of the investors in the Existing Entities. The Stipulation of Settlement states that counsel for the plaintiff class satisfied themselves that they have received adequate access to relevant information, including the independent valuer's valuation process and methodology, that the disclosures in the Registration Statement on Form S-4, as amended, are appropriate, that the consolidation presents potential benefits, including the opportunity for liquidity and capital appreciation, that merit the investors' serious consideration and that each of the named class representatives intends to support the consolidation as modified. The Stipulation of Settlement further states that counsel for the plaintiff class are satisfied that the claims regarding tax implications, enhanced disclosures, appraisals and exchange values of the properties that would be consolidated into our company, and the interests of the investors in the Existing Entities, have been addressed adequately, and they have concluded that the settlement pursuant to the Stipulation of Settlement and opportunity to consider the proposed consolidation on the basis of revised consent solicitations are fair, reasonable, adequate and in the best interests of the plaintiff class.

The defendants in the Stipulation of Settlement denied that they committed any violation of law or breached any of their duties and did not admit that they had any liability to the plaintiffs.

The terms of the settlement include, among other things (i) a payment of $55.0 million, with a minimum of 80% in cash and maximum of 20% in freely-tradable shares of ESRT common stock and/or freely-tradable operating partnership units to be distributed, after reimbursement of plaintiffs' counsel's court-approved expenses and payment of plaintiffs' counsel's court-approved attorneys' fees (which are included within the $55.0 million settlement payment) and, in the case of shares of ESRT common stock and/or operating partnership units, after the termination of specified lock-up periods, to investors in the Existing Entities pursuant to a plan of allocation to be prepared by counsel for plaintiffs; (ii) defendants' agreement that (a) the Offering would be on the basis of a firm commitment underwriting; (b) if, during the solicitation period, any of the three subject LLCs' percentage of total exchange value is lower than what was stated in the final prospectus/consent solicitation with respect to the consolidation by 10% or more, such decrease would be promptly disclosed by defendants to investors in the subject LLCs; and (c) unless total gross proceeds of $600.0 million are raised in the Offering, defendants will not proceed with the consolidation without further approval of the subject LLCs; and (iii) defendants' agreement to make additional disclosures in the prospectus/consent solicitation with respect to the consolidation regarding certain matters (which are included therein). Investors in the Existing Entities will not be required to bear any portion of the settlement payment. The payment in settlement of the Original Class Actions will be made by the estate of Leona M. Helmsley and affiliates of Malkin Holdings LLC (provided that none of Malkin Holdings LLC's affiliates that would become our direct or indirect subsidiary in the consolidation will have any liability for such payment) and certain investors in the Existing Entities who agree to contribute. We will not bear any of the settlement payment.

The settlement further provides for the certification of a class of investors in the Existing Entities, other than defendants and other related persons and entities, and a release of any claims of the members of the class against the defendants and related persons and entities, as well as underwriters and other advisors. The release in the settlement excludes certain

F-30

claims, including but not limited to, claims arising from or related to any supplement to the Registration Statement on Form S-4 that is declared effective to which the plaintiffs' counsel objects in writing, which objection will not be unreasonably made or delayed, so long as plaintiffs' counsel has had adequate opportunity to review such supplement. There was no such supplement that plaintiff's counsel objected to in writing. The settlement was subject to court approval. It was not effective until such court approval is final, including the resolution of any appeal. Defendants continue to deny any wrongdoing or liability in connection with the allegations in the Original Class Actions.

On January 18, 2013, the parties jointly moved for preliminary approval of the settlement, for permission to send notice of the settlement to the class, and for the scheduling of a final settlement hearing. On January 28, 2013, six of the investors in Empire State Building Associates L.L.C. filed an objection to preliminary approval, and cross-moved to intervene in the Original Class Actions and for permission to file a separate complaint on behalf of the investors in Empire State Building Associates L.L.C. On February 21, 2013, the court denied the cross motion of such objecting investors, and the court denied permission for such objecting investors to file a separate complaint as part of the Original Class Actions, but permitted them to file a brief solely to support their allegation that the buyout would deprive non-consenting investors in Empire State Building Associates L.L.C. of “fair value” in violation of the New York Limited Liability Company Law. The court rejected the objecting investors’ assertion that preliminary approval be denied and granted preliminary approval of the settlement.

Pursuant to a decision issued on April 30, 2013, the court rejected the allegation regarding the New York Limited Liability Company Law and ruled in Malkin Holdings LLC’s favor, holding that such buyout provisions are legally binding and enforceable and that investors do not have the rights they claimed under the New York Limited Liability Company Law.

On May 2, 2013, the court held a hearing regarding final approval of the Original Class Actions settlement, at the conclusion of which the court stated that it intended to approve the settlement. On May 17, 2013, the court issued its Opinion and Order. The court rejected the objections by all objectors and upheld the settlement in its entirety. Of the approximately 4,500 class members who are investors in all of the Existing Entities included in the consolidation, 12 opted out of the settlement. Those who opted out will not receive any share of the settlement proceeds, but can pursue separate claims for monetary damages.

Also on May 17, 2013, the court issued its Opinion and Order on attorneys’ fees. Class counsel applied for an award of $15.0 million in fees and $295,895 in expenses, which the court reduced to $11.59 million in fees and $265,282 in expenses (which are included within the $55.0 million settlement payment).

The investors who challenged the buyout provision filed a notice of appeal of the court’s April 30, 2013 decision and moved before the appellate court for a stay of all proceedings relating to the settlement, including such a stay as immediate interim relief. On May 1, 2013, their request for immediate interim relief was denied. On May 13, 2013, Malkin Holdings LLC filed its brief in opposition to the motion for the stay. On June 18, 2013, the appellate court denied the motion for the stay. On July 16, 2013, these investors filed their brief and other supporting papers on their appeal of the April 30, 2013 decision, which are required to perfect the appeal. On September 4, 2013, Malkin Holdings LLC filed its brief on the appeal, and also moved to dismiss the appeal on the grounds that these investors lack standing to pursue it. Malkin Holdings LLC contended that these investors were not entitled to appraisal under the New York Limited Liability Company Law because, among other reasons (i) they are not members of Empire State Building Associates L.L.C., and only members have such rights; (ii) the transaction in question is not a merger or consolidation as defined by statute, and appraisal only applies in those transactions; and (iii) when Empire State Building Associates L.L.C. was converted into a limited liability company, the parties agreed that no appraisal would apply. Moreover, Malkin Holdings LLC contended that only the 12 investors who opted out of the class action settlement could pursue appraisal, because that settlement contains a broad release of (and there is an associated bar order from the court preventing) any such claims. Malkin Holdings LLC further noted that of the six investors attempting to pursue the appeal, only two had in fact opted out of the class action settlement. On September 13, 2013, these investors filed their reply brief on the appeal, and opposed the motion to dismiss. On September 19, 2013, Malkin Holdings LLC filed its reply brief on the motion to dismiss. On October 3, 2013, the appeals court denied the motion to dismiss without prejudice to address the matter directly on the appeal, effectively referring the issues raised in the motion to the panel that was to hear the appeal itself. The appeals court heard argument on November 21, 2013, and in a Decision and Order dated February 25, 2014, it affirmed the trial court’s ruling.

In addition, on June 20, 2013, these same investors, and one additional investor who also opposed the settlement of the Original Class Action, filed additional notices of appeal from the trial court’s rulings in the Original Class Actions. These notices of appeal related to (i) the order entered February 22, 2013 granting preliminary approval of the Original Class Action settlement and setting a hearing for final approval; (ii) the order entered February 26, 2013, refusing to sign a proposed order to show cause for a preliminary injunction regarding the consolidation; (iii) an order entered April 2, 2013, denying the motion to

F-31

intervene and to file a separate class action on behalf of Empire State Building Associates L.L.C. investors; (iv) the order entered April 10, 2013, refusing to sign the order to show cause seeking to extend the deadline for class members to opt out of the Original Class Action settlement; (v) the Final Judgment and Order entered May 17, 2013; (vi) the order entered May 17, 2013 approving the Original Class Action settlement; and (vii) the order entered May 17, 2013 awarding class counsel attorneys’ fees and costs. On January 6, 2014, Class counsel moved to dismiss these additional appeals on the grounds that they were not timely perfected by filing an appellate brief and record. On February 6, 2014, the appeals court granted the motion unless the appeals were perfected by March 17, 2014.

On March 27, 2014, the investors who challenged the buyout provision moved in the appellate court for reargument or in the alternative for leave to appeal the appeals court’s ruling to the New York Court of Appeals. Opposition to the motion was filed on April 7, 2014. The appellate court denied the motion on May 22, 2014. The investors moved in the New York Court of Appeals for leave to appeal on June 26, 2014. Opposition to this motion was filed on July 11, 2014 and the court dismissed the motion by order dated September 18, 2014. On October 20, 2014, the investors moved to re-argue that dismissal. That motion was denied on December 17, 2014, and counsel for these investors has represented that the investors do not intend to pursue further appellate review of the court’s April 30, 2013 ruling rejecting the challenge to the buyout provision. On March 3, 2015, plaintiffs' counsel filed a motion with the court for its approval of distribution of the net settlement fund. In that motion plaintiffs' counsel also asked for additional fees and expenses to be paid out of the fund. On March 20, 2015, Malkin Holdings LLC filed a response to that motion in which it supported distribution of the fund and took no position on additional fees and expenses. No opposition to the motion was filed and the court granted the motion. Substantially all of the net settlement fund has been distributed to the class, but a small amount remains outstanding.

On March 14, 2014, one of the investors who had filed a notice of appeal from the trial court’s rulings in the Original Class Actions noted above perfected an appeal from the court’s May 17, 2013 Final Judgment and Order and orders approving the Original Class Action Settlement and awarding class counsel attorneys’ fees and costs. By stipulation of all counsel to the appeal dated September 12, 2014, the appeal was dismissed with prejudice. No other appeals were filed by the March 17, 2014 deadline set by the appeals court in its February 6, 2014 order. The Original Class Actions Settlement is final and non-appealable.

In addition, commencing December 24, 2013, four putative class actions, or the "Second Class Actions," were filed in New York State Supreme Court, New York County, against Malkin Holdings LLC, Peter L. Malkin, Anthony E. Malkin and Thomas N. Keltner, Jr. on behalf of former investors in Empire State Building Associates L.L.C. Generally, the Second Class Actions alleged that the defendants breached their fiduciary duties and were unjustly enriched. One of the Second Class Actions named us and our operating partnership as defendants, alleging that they aided and abetted the breaches of fiduciary duty. The Second Class Actions were consolidated on consent, and co-lead class counsel was appointed by order dated February 11, 2014. A Consolidated Amended Complaint was filed February 7, 2014, which did not name us or our operating partnership as defendants. It seeks monetary damages. On March 7, 2014, defendants filed a motion to dismiss the Second Class Actions, which the plaintiffs opposed and was fully submitted to the court on April 28, 2014. The court heard oral arguments on the motion on July 7, 2014, and the motion to dismiss was granted in a ruling entered July 21, 2014. The plaintiffs filed a notice of appeal on August 8, 2014. On January 12, 2015, the plaintiffs filed a motion to supplement the record on appeal to include additional materials from the Original Class Action, which the defendants opposed. The motion was denied on March 5, 2015. The plaintiffs perfected this appeal by filing their brief and the appellate record with the court on March 23, 2015. Oral argument on the appeal was held on October 28, 2015. On November 25, 2015, the appellate court affirmed dismissal of the Second Class Actions. The plaintiffs have moved the appellate court for leave to appeal to the New York Court of Appeals. That motion is fully submitted and awaiting a ruling from the appellate court.

We will incur costs in connection with this litigation. If an appeal were successful and the court were ultimately to rule against the defendants, there is a risk that it could have a material adverse effect on us, which could take the form of monetary damages or other equitable relief. At this time, due to the spectrum of remedies which may result from the outcome of the matter and the difficulty in calculating and allocating damages (if any) among the defendants, we cannot reasonably assess the timing or outcome of this litigation and any related indemnification obligations, estimate the amount of loss, or assess their effect, if any, on our financial statements.

On or about October 14, 2014, the 12 investors (out of approximately 4,500 investors covered by the Original Class Actions) who opted out of the Original Class Actions filed an arbitration with the American Arbitration Association against Peter L. Malkin, Anthony E. Malkin, Thomas N. Keltner, Jr., and Malkin Holdings LLC, as respondents, alleging breach of fiduciary duty and related claims in connection with the consolidation. The statement of claim in that arbitration seeks monetary damages and declaratory relief. The respondents filed an answering statement and counterclaims. On December 18, 2014, these claimants also filed a complaint in the United States District Court for the Southern District of New York alleging

F-32

the same claims that they asserted in the arbitration. As alleged in the complaint, the claimants filed this lawsuit to toll the statute of limitations on their claims in the event it is determined that the claims are not subject to arbitration, and they plan to move to stay the lawsuit in favor of the pending arbitration. On February 2, 2015, the claimants filed an amended complaint adding an additional claim and making other non-substantive modifications to the original complaint. On March 12, 2015, the court stayed the action on consent of all parties pending the arbitration. Discovery in the arbitration is proceeding and the hearings are scheduled to commence May 24, 2016.

As with the prior claims challenging the consolidation and related matters, the defendants believe the allegations in the arbitration are entirely without merit and they intend to defend vigorously.

In connection with the Offering and formation transactions, we and ESRT entered into indemnification agreements with ESRT's directors, executive officers and chairman emeritus, providing for the indemnification by us and ESRT for certain liabilities and expenses incurred as a result of actions brought, or threatened to be brought, against them. As a result, Anthony E. Malkin, Peter L. Malkin and Thomas N. Keltner, Jr. have defense and indemnity rights from us and ESRT with respect to the Second Class Actions and the above-referenced arbitration.

Additionally, there is a risk that other third parties will assert claims against us, Malkin Holdings LLC, or any other party entitled to defense and indemnity from us, including, without limitation, claims that Malkin Holdings LLC breached its fiduciary duties to investors in the Existing Entities or that the consolidation violates the relevant operating agreements, and third parties may commence litigation related to such claims. As a result, we may incur costs associated with defending or settling such litigation or paying any judgment if we lose.

Ground Lease Commitments

We make payments under ground leases related to three of our properties. Minimum rent is expensed on a straight-line basis over the non-cancellable term of the leases. The ground leases are due to expire between the years 2050 and 2077. Future minimum lease payments to be paid over the terms of the leases are as follows (amounts in thousands):



2016	$	1,518
2017	1,518
2018	1,518
2019	1,518
2020	1,518
Thereafter	56,730
Total	$	64,320

Unfunded Capital Expenditures

At December 31, 2015, we estimate that we will incur approximately $51.2 million of capital expenditures (including tenant improvements and leasing commissions) on our properties pursuant to existing lease agreements. We expect to fund these capital expenditures with operating cash flow, additional property level mortgage financings, our unsecured credit facility, cash on hand and other borrowings. Future property acquisitions may require substantial capital investments for refurbishment and leasing costs. We expect that these financing requirements will be met in a similar fashion.

Concentration of Credit Risk

Financial instruments that subject us to credit risk consist primarily of cash, restricted cash, tenant and other receivables and deferred rent receivables. At December 31, 2015, we held on deposit at various major financial institutions cash and cash equivalents and restricted cash balances in excess of amounts insured by the FDIC.

Real Estate Investments

Our properties are located in Manhattan, New York; Fairfield County, Connecticut; and Westchester County, New York. The latter locations are suburbs of the city of New York. The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory and social factors affecting the markets in which the tenants operate. We perform ongoing credit evaluations of our tenants for potential credit losses.

F-33

Tenant Credit Evaluations

Our investments in real estate properties are subject to risks incidental to the ownership and operation of commercial real estate. These risks include, among others, the risks normally associated with changes in general economic conditions, trends in the real estate industry, creditworthiness of tenants, competition of tenants and customers, changes in tax laws, interest rate levels, the availability and cost of financing, and potential liability under environmental and other laws.

We may require tenants to provide some form of credit support such as corporate guarantees and/or other financial guarantees and we perform ongoing credit evaluations of tenants. Although the tenants operate in a variety of industries, to the extent we have a significant concentration of rental revenue from any single tenant, the inability of that tenant to make its lease payments could have an adverse effect on our company.

Major Customers and Other Concentrations

For the year ended December 31, 2015, other than three tenants who account for 6.7%, 3.5% and 2.0% of rental revenues, no other tenant in our portfolio account for more than 2.0% of rental revenues. For the year ended December 31, 2014, other than three tenants who accounted for 8.2%, 4.2% and 2.3% of rental revenues, no other tenant in our portfolio accounted for more than 2.0% of rental revenues.

For the years ended December 31, 2015 and 2014, five properties accounted for the following percent of total rental revenues. In 2015, no other property accounted for more than 5.0% of total rental revenues.



	Year Ended December 31,
	2015		2014
Empire State Building	31.4	%	33.9	%
One Grand Central Place	12.2	%	13.5	%
111 West 33rd Street (formerly known as 112 West 34th Street)	8.3	%	4.4	%
1400 Broadway	7.7	%	3.9	%
First Stamford Place	6.5	%	7.0	%

Asset Retirement Obligations

We are required to accrue costs that we are legally obligated to incur on retirement of our properties which result from acquisition, construction, development and/or normal operation of such properties. Retirement includes sale, abandonment or disposal of a property. Under that standard, a conditional asset retirement obligation represents a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement is conditional on a future event that may or may not be within a company’s control and a liability for a conditional asset retirement obligation must be recorded if the fair value of the obligation can be reasonably estimated. Environmental site assessments and investigations have identified asbestos or asbestos-containing building materials in certain of our properties. As of December 31, 2015, management has no plans to remove or alter these properties in a manner that would trigger federal and other applicable regulations for asbestos removal, and accordingly, the obligations to remove the asbestos or asbestos-containing building materials from these properties have indeterminable settlement dates. As such, we are unable to reasonably estimate the fair value of the associated conditional asset retirement obligation. However ongoing asbestos abatement, maintenance programs and other required documentation are carried out as required and related costs are expensed as incurred.

Other Environmental Matters

Certain of our properties have been inspected for soil contamination due to pollutants, which may have occurred prior to our ownership of these properties or subsequently in connection with its development and/or its use. Required remediation to such properties has been completed and as of December 31, 2015, management believes that there are no obligations related to environmental remediation other than maintaining the affected sites in conformity with the relevant authority’s mandates and filing the required documents. All such maintenance costs are expensed as incurred. We expect that resolution of the environmental matters relating to the above will not have a material impact on our business, assets, consolidated and combined financial condition, results of operations or liquidity. However, we cannot be certain that we have identified all environmental liabilities at our properties, that all necessary remediation actions have been or will be undertaken at our properties or that we will be indemnified, in full or at all, in the event that such environmental liabilities arise.

Insurance Coverage

F-34

We carry insurance coverage on our properties of types and in amounts with deductibles that we believe are in line with coverage customarily obtained by owners of similar properties.

Multiemployer Pension and Defined Contribution Plans

We contribute to a number of multiemployer defined benefit pension plans under the terms of collective bargaining agreements that cover our union-represented employees. The risks of participating in these multiemployer plans are different from single-employer plans in the following aspects:


•	Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.


•	If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.


•	If we choose to stop participating in some of our multiemployer plans, we may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability.

We participate in various unions. The union which has significant employees and costs is as follows:

32BJ

We participate in the Building Service 32BJ, or Union, Pension Plan and Health Plan. The Pension Plan is a multi-employer, non-contributory defined benefit pension plan that was established under the terms of collective bargaining agreements between the Service Employees International Union, Local 32BJ, the Realty Advisory Board on Labor Relations, Inc. and certain other employers. This Pension Plan is administered by a joint board of trustees consisting of union trustees and employer trustees and operates under employer identification number 13-1879376. The Pension Plan year runs from July 1 to June 30. Employers contribute to the Pension Plan at a fixed rate on behalf of each covered employee. Separate actuarial information regarding such pension plans is not made available to the contributing employers by the union administrators or trustees, since the plans do not maintain separate records for each reporting unit. However, on September 28, 2011, September 28, 2012, September 27, 2013, September 26, 2014, and September 28, 2015, the actuary certified that for the plan years beginning July 1, 2010, July 1, 2011 and July 1, 2012, July 1, 2013, July 1, 2014 and July 1, 2015, respectively, the Pension Plan was in critical status under the Pension Protection Act of 2006. The Pension Plan trustees adopted a rehabilitation plan consistent with this requirement. For each of the years ended June 30, 2015, 2014 and 2013, the Pension Plan received contributions from employers totaling $242.3 million, $224.5 million and $221.9 million, respectively.

The Health Plan was established under the terms of collective bargaining agreements between the Union, the Realty Advisory Board on Labor Relations, Inc. and certain other employers. The Health Plan provides health and other benefits to eligible participants employed in the building service industry who are covered under collective bargaining agreements, or other written agreements, with the Union. The Health Plan is administered by a Board of Trustees with equal representation by the employers and the Union and operates under employer identification number 13-2928869. The Health Plan receives contributions in accordance with collective bargaining agreements or participation agreements. Generally, these agreements provide that the employers contribute to the Health Plan at a fixed rate on behalf of each covered employee. For the years ended June 30, 2015, 2014 and 2013, the Health Plan received contributions from employers totaling $1.1 billion, $1.0 billion and $923.5 million, respectively.

Terms of Collective Bargaining Agreements

The most recent collective bargaining agreement for Local 32BJ commenced from January 1, 2016 through December 31, 2019 (prior agreement was from January 1, 2012 through December 31, 2015).

Contributions

Contributions we made to the multi-employer plans for the years ended December 31, 2014, 2013 and 2012 are included in the table below (amounts in thousands):

F-35



Benefit Plan	2015		2014		2013
Pension Plans (pension and annuity)*	$	3,077	$	2,871	$	1,201
Health Plans**	8,296		7,628		3,319
Other***	619		319		232
Total plan contributions	$	11,992	$	10,818	$	4,752


*	Pension plans include $0.7 million, $0.8 million and $0.4 million for the years ended 2015, 2014 and 2013, respectively, to multiemployer plans not discussed above.

** Health plans include $1.4 million, $1.5 million and $0.8 million for the years ended 2015, 2014 and 2013, respectively, to multiemployer plans not discussed above.

*** Other includes $0.2 million, $0.08 million and $0.05 million for the years ended 2015, 2014 and 2013, respectively, in connection with other multiemployer plans not discussed above for union costs which were not itemized between pension and health plans.

The increase in plan contributions in 2015 is mainly due to the acquisition of two properties during July 2014 which resulted in a full year's contributions in 2015 for the employees covered by these benefit plans.

11. Capital

As of December 31, 2015, there were approximately 267.6 million operating partnership units outstanding, of which approximately 120.0 million, or 44.9%, were owned by ESRT and approximately 147.6 million, or 55.1%, were owned by other partners, including ESRT directors, members of ESRT senior management and other ESRT employees.

Long-term incentive plan ("LTIP") units are a special class of partnership interests. Each LTIP unit awarded will be deemed equivalent to an award of one share of ESRT stock under the 2013 Equity Incentive Plan ("2013 Plan"), reducing the availability for other equity awards on a one-for-one basis. The vesting period for LTIP units, if any, will be determined at the time of issuance. Cash distributions on each LTIP unit, whether vested or not, will be the same as those made on the operating partnership units. Under the terms of the LTIP units, we will revalue for tax purposes its assets upon the occurrence of certain specified events, and any increase in valuation from the time of grant until such event will be allocated first to the holders of LTIP units to equalize the capital accounts of such holders with the capital accounts of unitholders. Subject to any agreed upon exceptions, once vested and having achieved parity with unitholders, LTIP units are convertible into operating partnership units on a one-for-one basis.

Private Perpetual Preferred Units

During August 2014, we completed an exchange offer whereby we issued 1,560,360 new Private Perpetual Preferred Units ("Preferred Units") in exchange for OP Units on a one-for-one basis, in reliance on Section 3(a)(9) of the Securities Act of 1933, as amended. The exchange offer was made only to then current holders of OP Units and was not made or offered to the public or holders of our common stock or any other security. The Preferred Units have a liquidation preference of $16.62 per unit and are entitled to receive cumulative preferential annual cash distributions of $0.60 per unit payable in arrears on a quarterly basis. The Preferred Units are not redeemable at the option of the holders and are redeemable at our option only in the case of specific defined events. In connection with this exchange offer, we incurred $1.4 million of costs, which were expensed as incurred and included in marketing, general, and administrative expenses.

Distributions

The following table summarizes the dividends declared and paid on our operating partnership units for the years ended December 31, 2015 and 2014 and the period from October 7, 2013 to December 31, 2013:

Total distributions paid to OP unitholders and Preferred unitholders during 2015 and 2014 totaled $91.9 million and $87.7 million, respectively. Total distributions paid to OP unitholders during 2013 totaled $19.5 million.

Incentive and Share-Based Compensation

The 2013 Plan provides for grants to our directors, employees and consultants of our company and ESRT consisting of stock options, restricted stock, dividend equivalents, stock payments, performance shares, LTIP units, stock appreciation rights and other incentive awards. An aggregate of approximately 12.2 million shares of ESRT common stock are authorized for issuance under awards granted pursuant to the 2013 Plan, and as of December 31, 2015, approximately 10.2 million shares of ESRT common stock remain available for future issuance.

In June 2015, we made grants of LTIP units to our non-employee directors under the 2013 Plan. At such time, we granted a total of 35,082 LTIP units that are subject to time-based vesting, with fair market values of $0.6 million. The awards vest ratably over three years from the date of the grant, subject generally to the director's continued service on our Board of Directors.

In February 2015, we made grants of LTIP units to executive officers under the 2013 Plan. At such time, we granted a total of 168,033 LTIP units that are subject to time-based vesting and 154,266 LTIP units that are subject to performance-based vesting, with fair market values of $2.9 million for the time-based vesting awards and $1.3 million for the performance-based vesting awards. The awards subject to time-based vesting vest ratably over four years from January 1, 2015, subject generally to the grantee's continued employment. The first installment vests on the first-year anniversary date of January 1, 2015 and the remainder will vest thereafter in three equal annual installments. The vesting of the LTIP units subject to performance-based vesting is based on the achievement of absolute and relative total stockholder return hurdles over a three-year performance period, commencing on January 1, 2015. Following the completion of the three-year performance period, our compensation committee will determine the number of LTIP units to which the grantee is entitled based on our performance relative to the performance hurdles set forth in the LTIP unit award agreements the grantee entered into in connection with the award grant. These units then vest in two installments, with the first installment vesting on January 1, 2018 and the second installment vesting on January 1, 2019, subject generally to the grantee's continued employment on those dates.

In February 2015, we made grants of LTIP units and restricted stock to certain other employees under the 2013 Plan.

The first installment vests on the first-year anniversary date of January 1, 2015 and the remainder will vest thereafter in three equal annual installments. The vesting of the awards subject to performance-based vesting is based on the achievement of absolute and relative total stockholder return hurdles over a three-year performance period, commencing on January 1, 2015. Following the completion of the three-year performance period, our compensation committee will determine the number of LTIP units or shares to which the grantee is entitled based on our performance relative to the performance hurdles set forth in the award agreements the grantee entered into in connection with the award grant. These units and shares

The first installment vested on January 1, 2015 and the remainder will vest thereafter in three equal annual installments. The vesting of the LTIP units subject to performance-based vesting is based on the achievement of absolute and relative total stockholder return hurdles over a three-year performance period, commencing on January 1, 2014. Following the completion of the three-year performance period, our compensation committee will determine the number of shares to which the grantee is entitled based on our performance relative to the performance hurdles set forth in the LTIP unit award agreements the grantee entered into in connection with the initial award grant.

F-38

In January and April 2014, we made grants of LTIP units and ESRT restricted stock to certain other employees under the 2013 Plan.

These shares are subject to time-based and performance-based vesting, with the terms described above. We issued operating partnership units to ESRT for each share of restricted stock issued by ESRT.

Concurrently with the closing of the Offering and the adoption of the 2013 Plan, we and ESRT made grants of LTIP units to executive officers under the 2013 Plan. At such time, we granted a total of 440,192 LTIP units that are subject to time-based vesting and 146,730 LTIP units that are subject to performance-based vesting, with fair market values of $5.4 million for the time-based vesting awards and $0.9 million for the performance-based vesting awards. The awards subject to time-based vesting vest in four substantially equal installments, subject to the grantee's continued employment. The first installment vests on the first anniversary of the grant date and the remainder will vest thereafter in three equal annual installments. The vesting of the LTIP units subject to performance-based vesting is based on the achievement of absolute and relative total stockholder return hurdles over a three-year performance period, commencing on October 2, 2013. Following the completion of the three-year performance period, our compensation committee will determine the number of shares to which the grantee is entitled based on our performance relative to the performance hurdles set forth in the LTIP units award agreements the grantee entered into in connection with the initial award grant. These units then vest in two substantially equal installments, with the first installment vesting on the third anniversary of the grant date and the second installment vesting on the fourth anniversary of the grant date, subject to the grantee's continued employment on those dates.

Concurrently with the closing of the Offering and the adoption of the 2013 Plan, we and ESRT made grants of LTIP units and restricted stock to certain other employees under the 2013 Plan. At such time, we granted a total of 193,059 LTIP units and 119,146 shares of restricted stock that are subject to time-based vesting and 64,352 LTIP units and 39,706 shares of restricted stock that are subject to performance-based vesting, with fair market values of $3.9 million for the time-based vesting awards and $0.6 million for the performance-based vesting awards. These shares are subject to time-based and performance-based vesting, with the terms described above.

Concurrently with the closing of the Offering and the adoption of the 2013 Plan, we made grants of LTIP units to our non-employee directors under the 2013 Plan. At such time, we granted a total of 69,228 LTIP units that are subject to time-based vesting, with fair market values of $0.9 million. The awards vest in three substantially equal installments, subject to the director's continued service on our Board of Directors. The first installment vests on the first anniversary of the grant date and the remainder will vest thereafter in two equal annual installments.

Share-based compensation is measured at the fair value of the award on the date of grant and recognized as an expense on a straight-line basis over the vesting period. For the performance-based LTIP units and restricted stock awards, the fair value of the awards was estimated using a Monte Carlo Simulation model. Our stock price, along with the prices of the comparative indexes, is assumed to follow the Geometric Brownian Motion Process. Geometric Brownian motion is a common assumption when modeling in financial markets, as it allows the modeled quantity (in this case, the stock price) to vary randomly from its current value and take any value greater than zero. The volatilities of the returns on our stock price and the comparative indexes were estimated based on implied volatilities and historical volatilities using a six-year look-back period. The expected growth rate of the stock prices over the performance period is determined with consideration of the risk free rate as of the grant date. For LTIP units and restricted stock grants that are time-vesting, we estimate the stock compensation expense based on the fair value of the stock at the grant date.

Share-based compensation expense has been adjusted by an amount of estimated forfeitures. Forfeitures are estimated based on historical experience at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Based on an analysis of historical data, we have calculated a 0% annual forfeiture rate for members of the Board of Directors, a 0% annual forfeiture rate for executive officers, and for all other employees a 5% annual forfeiture rate. We reevaluate this analysis periodically and adjust these estimated forfeiture rates as necessary. To the extent actual results or updated estimates differ from our current estimates, such amounts will be recorded as a cumulative adjustment in the period estimates are revised.

LTIP units and ESRT restricted stock issued during the year ended December 31, 2015, 2014 and 2013 were valued at $6.6 million, $5.4 million and $11.7 million, respectively. The weighted-average per unit or share fair value was $13.36, $10.65 and $10.89 for grants issued in 2015, 2014 and 2013, respectively. The per unit or share granted in 2015 was estimated on the respective dates of grant using the following assumptions: an expected life of 3.0 and 2.9 years, a dividend rate of 1.9%, a risk-free interest rate of 0.8% and 1.0%, and an expected price volatility between 24.0% and 29.0%. The per unit or share

F-39

granted in 2014 was estimated on the respective dates of grant using the following assumptions: an expected life of 3.0 years, a dividend rate of 2.60% a risk-free interest rate of 0.8%, and an expected price volatility of 26.0%. The per unit or share granted in 2013 was estimated on the date of grant using the following assumptions: an expected life of 3.0 years, a dividend rate of 2.60%, a risk-free interest rate of 0.66%, and an expected price volatility of 28.0%.

No other stock options, dividend equivalents, or stock appreciation rights were issued or outstanding in 2015, 2014 and 2013.

The following is a summary of ESRT restricted stock and LTIP unit activity for the year ended December 31, 2015:

The total fair value of LTIP units and restricted stock that vested during 2015 and 2014 was $3.5 million and $3.0 million, respectively.

The LTIP unit and ESRT restricted stock award agreements will immediately vest when a grantee attains the (i) age of 60 and (ii) the date on which grantee has first completed ten years of continuous service with our company or its affiliates. For award agreements that qualify, we recognize noncash compensation expense on the grant date for the time-based awards and ratably over the vesting period for the performance-based awards, and accordingly we recognized $0.5 million, $0.2 million and $2.3 million for the years ended December 31, 2015 and 2014 and the period October 7, 2013 through December 31, 2013, respectively. Unrecognized compensation expense was $0.1 million at December 31, 2015, which will be recognized over a weighted average period of 1.2 years.

For the remainder of the LTIP unit and ESRT restricted stock awards, we recognize noncash compensation expense ratably over the vesting period, and accordingly, we recognized $5.0 million, $3.5 million and $0.7 million in noncash compensation expense for the years ended December 31, 2015 and 2014 and the period October 7, 2013 through December 31, 2013, respectively. Unrecognized compensation expense was $10.3 million at December 31, 2015, which will be recognized over a weighted average period of 2.3 years.

12. Related Party Transactions

Formation Transactions

Each property, except for 1400 Broadway and 111 West 33rd Street (formerly known as 112 West 34th Street), that is owned by us was owned directly or indirectly by the entities comprising our predecessor or was a property in which our predecessor had a non-controlling interest. Each of the existing entities had entered into a contribution agreement with us and ESRT in connection with the formation transactions, pursuant to which substantially concurrently with the completion of the Offering it contributed its assets (including its ownership interests in any of the properties) and liabilities to us in exchange for shares of ESRT common stock, operating partnership units and/or cash, which it distributed to its equity owners in accordance with their individual elections. Each of our predecessor’s management companies had entered into a merger agreement with us and ESRT in connection with the formation transactions, pursuant to which certain of our subsidiaries merged with and into such management company or pursuant to which such management company merged with and into subsidiaries of us in exchange for shares of ESRT's common stock and/or operating partnership units, which was issued to the equity owners of such management company. In addition, each of (i) the Malkin Group (as defined below) and (ii) the estate of Leona M. Helmsley and entities affiliated therewith, including the Leona M. and Harry B. Helmsley Charitable Trust, entered into contribution agreements and merger agreements with us and ESRT, pursuant to which each of them contributed their direct or indirect interests in certain existing entities to us in exchange for operating partnership units, shares of ESRT common stock and/or cash. The operating partnership units that were issued and shares of ESRT common stock that ESRT issued in the formation transactions to investors in the public existing entities were registered pursuant to a registration statement on Form S-4 that we separately filed with the SEC. To the extent that ESRT or its subsidiaries (other than us) were a party directly to certain mergers in the formation transactions, ESRT contributed the assets and liabilities received in such merger transactions to us in exchange for operating partnership units. The value of the shares of ESRT's common stock and operating partnership units that we issued, and the amount of cash that we paid, in connection with the formation transactions aggregated $2.8 billion based on the actual public offering price of ESRT's Class A common stock in the Offering. The existing entities and our predecessor’s management companies declared final distributions, inclusive of reimbursement of expenses incurred in connection with the formation transactions, to the investors in such entities, including members of our senior management team and certain of our directors, in an amount of approximately $180.0 million in the aggregate, and of which $38.9 million was paid to the Malkin Group, including Peter L. Malkin and Anthony E. Malkin, in accordance to their ownership interests in each applicable existing entity and predecessor management company.

Under the contribution and merger agreements, Anthony E. Malkin directly and/or indirectly received 210,289 shares of ESRT Class A common stock, 586,095 shares of ESRT Class B common stock, and 28,718,631 operating partnership units, representing, in aggregate, a 12.0% beneficial interest in ESRT and the Company on a fully diluted basis, and Peter L. Malkin directly and/or indirectly received 2,772 shares of ESRT Class A common stock, 100,084 shares of ESRT Class B common stock, and 6,027,867 operating partnership units representing, in aggregate, a 2.5% beneficial interest in ESRT and the Company on a fully diluted basis. The Malkin Group, which includes Anthony E. Malkin, Peter L. Malkin and their related parties and affiliates, directly and/or indirectly received 396,025 shares of ESRT Class A common stock, 747,435 shares of ESRT Class B common stock, and 37,748,249 operating partnership units, representing, in aggregate, a 15.8% beneficial interest in ESRT and the Company on a fully diluted basis. Other members of ESRT's senior management team received an aggregate of 1,167,336 operating partnership units, and 2,407 shares of ESRT's Class B common stock representing a 0.5% interest in ESRT and the Company on a fully diluted basis.

We did not conduct arm’s-length negotiations with the parties involved regarding the terms of the formation transactions. In the course of structuring the formation transactions, certain members of ESRT's senior management team and other contributors had the ability to influence the type and level of benefits they received from us.

The term “Malkin Group” means all of the following, as a group: Anthony E. Malkin, Peter L. Malkin and each of their spouses and lineal descendants (including spouses of such descendants), any estates of any of the foregoing, any trusts now or hereafter established for the benefit of any of the foregoing, or any corporation, partnership, limited liability company or other legal entity controlled by Anthony E. Malkin or any permitted successor in such entity for the benefit of any of the foregoing; provided, however that solely with respect to tax protection rights and parties who entered into the contribution agreements described in this Annual Report on Form 10-K, the Malkin Group shall also include the lineal descendants of Lawrence A. Wien and his spouse (including spouses of such descendants), any estates of the foregoing, any trusts now or

F-41

hereafter established for the benefit of any of the foregoing, or any corporation, partnership, limited liability company or other legal entity controlled by Anthony E. Malkin for the benefit of the foregoing.

Tax Protection Agreement

In connection with the completion of the Offering and the related formation transactions, we and ESRT entered into a tax protection agreement with Anthony E. Malkin and Peter L. Malkin that is intended to protect the Malkin Group and an additional third party investor in Metro Center (who was one of the original landowners and was involved in the development of the property) against certain of the tax consequences described above to a limited extent.

First, this agreement provides that we will not sell, exchange, transfer or otherwise dispose of four properties, which we refer to in this section as protected assets, or any interest in a protected asset until October 7, 2025, with respect to First Stamford Place and the later of (x) October 7, 2021 or (y) the death of Peter L. Malkin and Isabel W. Malkin who are 82 and 79 years old, respectively, for the three other protected assets, Metro Center, 10 Bank Street and 1542 Third Avenue, unless:

(1)Anthony E. Malkin consents to the sale, exchange, transfer or other disposition; or

(2)we deliver to each protected party thereunder a cash payment intended to approximate the tax liability arising from the recognition of the pre-contribution built-in gain resulting from the sale, exchange, transfer or other disposition of such protected asset (with the pre-contribution “built-in gain” being not more than the taxable gain that would have been recognized by such protected party had the protected asset been sold for fair market value in a taxable transaction at the time of the consolidation) plus an additional amount so that, after the payment of all taxes on amounts received pursuant to the agreement (including any tax liability incurred as a result of receiving such payment), the protected party retains an amount equal to such protected party’s total tax liability incurred as a result of the recognition of the pre-contribution built-in gain pursuant to such sale, exchange, transfer or other disposition; or

(3)the disposition does not result in a recognition of any built-in gain by the protected party.

Second, with respect to the Malkin Group, including Anthony E. Malkin and Peter L. Malkin, and one additional third party investor in Metro Center (who was one of the original landowners and was involved in the development of the property), to protect against gain recognition resulting from a reduction in such continuing investor’s share of the operating liabilities, the agreement provides that during the period from October 7, 2013 until such continuing investor owns less than the aggregate number of operating partnership units and shares of ESRT common stock equal to 50% of the aggregate number of such units and shares they received in the related formation transactions, which we refer to in this section as the tax protection period, we will (i) refrain from prepaying any amounts outstanding under any indebtedness secured by the protected assets and (ii) use our commercially reasonable efforts to refinance such indebtedness at or prior to maturity at its current principal amount, or, if we are unable to refinance such indebtedness at its current principal amount, at the highest principal amount possible. The agreement also provides that, during the tax protection period, we will make available to such continuing investors the opportunity (i) to enter into a “bottom dollar” guarantee of their allocable share of $160.0 million of our aggregate indebtedness meeting certain requirements or (ii) in the event we have recourse debt outstanding and such a continuing investor agrees in lieu of guaranteeing debt pursuant to clause (i) above, to enter into a deficit restoration obligation, in each case, in a manner intended to provide an allocation of our liabilities to the continuing investor. In the event that a continuing investor guarantees our debt, such continuing investor will be responsible, under certain circumstances, for the repayment of the guaranteed amount to the lender in the event that the lender would otherwise recognize a loss on the loan, such as, for example, if property securing the loan was foreclosed and the value was not sufficient to repay a certain amount of the debt. A deficit restoration obligation is a continuing investor’s obligation, under certain circumstances, to contribute a designated amount of capital to us upon our liquidation in the event that our assets are insufficient to repay our liabilities.

Because we expect that we will at all times have sufficient liabilities to allow us to meet our obligations to allocate liabilities to our partners that are protected parties under the tax protection agreement, our indemnification obligation with respect to “certain tax liabilities” would generally arise only in the event that we dispose in a taxable transaction of a protected asset within the period specified above in a taxable transaction. In the event of such a disposition, the amount of our indemnification obligation would depend on several factors, including the amount of “built-in gain,” if any, recognized and allocated to the indemnified partners with respect to such disposition and the effective tax rate to be applied to such gain at the time of such disposition.

F-42

Our partnership agreement requires that allocations with respect to such acquired property be made in a manner consistent with Section 704(c) of the Code. Treasury Regulations issued under Section 704(c) of the Code provide partnerships with a choice of several methods of allocating book-tax differences. Under the tax protection agreement, we have agreed to use the “traditional method” for accounting for book-tax differences for the properties acquired by us in the consolidation. Under the traditional method, which is the least favorable method from our perspective, the carryover basis of the acquired properties in our hands (i) may cause us to be allocated lower amounts of depreciation and other deductions for tax purposes than would be allocated to us if all of the acquired properties were to have a tax basis equal to their fair market value at the time of acquisition and (ii) in the event of a sale of such properties, could cause us to be allocated gain in excess of its corresponding economic or book gain (or taxable loss that is less than its economic or book loss), with a corresponding benefit to the partners transferring such properties to us for interests in us.

Registration Rights

We entered into a registration rights agreement with certain persons receiving shares of ESRT common stock or operating partnership units in the formation transactions, including certain members of ESRT's senior management team and our other continuing investors. In connection therewith, on October 7, 2014, which we refer to as the shelf effective date, we filed an automatically effective shelf registration statement, along with a prospectus supplement, with respect to, among other things, shares of ESRT Class A common stock that may be issued upon redemption of operating partnership units or issued upon conversion of shares of ESRT Class B common stock to continuing investors in the public existing entities. Pursuant to the registration rights agreement, under certain circumstances, ESRT will also be required to undertake an underwritten offering upon the written request of the Malkin Group, which we refer to as the holder, provided (i) the registrable shares to be registered in such offering will have a market value of at least $150.0 million, (ii) ESRT will not be obligated to effect more than two underwritten offerings during any 12-month period following the shelf effective date; and (iii) the holder will not have the ability to effect more than four underwritten offerings. In addition, if ESRT files a registration statement with respect to an underwritten offering for its own account or on behalf of the holder, the holder will have the right, subject to certain limitations, to register such number of registrable shares held by him, her or it as each such holder requests. With respect to underwritten offerings on behalf of the holder, ESRT will have the right to register such number of primary shares as it requests; provided, however, that if cut backs are required by the managing underwriters of such an offering, ESRT's primary shares shall be cutback first (but in no event will our shares be cut back to less than $25.0 million).

ESRT has also agreed to indemnify the persons receiving rights against specified liabilities, including certain potential liabilities arising under the Securities Act, or to contribute to the payments such persons may be required to make in respect thereof. ESRT has agreed to pay all of the expenses relating to the registration and any underwritten offerings of such securities, including, without limitation, all registration, listing, filing and stock exchange or FINRA fees, all fees and expenses of complying with securities or “blue sky” laws, all printing expenses and all fees and disbursements of counsel and independent public accountants retained by ESRT, but excluding underwriting discounts and commissions, any out-of-pocket expenses (except ESRT will pay any holder’s out-of-pocket fees (including disbursements of such holder’s counsel, accountants and other advisors) up to $25,000 in the aggregate for each underwritten offering and each filing of a resale shelf registration statement or demand registration statement), and any transfer taxes. In connection with the shelf registration statement that we filed on October 7, 2014, we incurred expenses of approximately $0.5 million.

Employment Agreement and Change in Control Severance Agreements

ESRT entered into an employment agreement with Anthony E. Malkin, which provides for salary, bonuses and other benefits, including among other things, severance benefits upon a termination of employment under certain circumstances and the issuance of equity awards. In addition, ESRT entered into change in control severance agreements with Thomas P. Durels, David A. Karp, Thomas N. Keltner, Jr. and John B. Kessler.

Indemnification of Our Directors and Officers

We entered into indemnification agreements with each of ESRT's directors, executive officers, chairman emeritus and certain other parties, providing for the indemnification by us for certain liabilities and expenses incurred as a result of actions brought, or threatened to be brought, against (i) ESRT's directors, executive officers and chairman emeritus and (ii) ESRT's executive officers, chairman emeritus and certain other parties who are former members, managers, securityholders, directors, limited partners, general partners, officers or controlling persons of our predecessor in their capacities.

Option Properties

F-43

On July 15, 2014, we acquired the ground lease at 1400 Broadway (the “1400 Property”) and the ground and operating leases at 111 West 33rd Street (formerly known as 112 West 34th Street) (including fee title interest in a small connected structure at 122 West 34th Street) (the “112 Property”), both office properties in midtown Manhattan (together, the “option properties”), from affiliates of our predecessor, pursuant to option agreements we had executed in connection with the Offering. Our subsidiary supervised each of the option properties pursuant to a management agreement entered into by our subsidiary and the owners of the option properties.

The 112 Property was acquired for approximately $423.6 million, consisting of assumption of existing mortgage debt, cash and shares of our Class A and Class B common stock and our operating partnership’s Series PR operating partnership units. In connection with the acquisition of the 112 Property, Anthony E. Malkin directly and/or indirectly received approximately $39.4 million, Peter L. Malkin directly and/or indirectly received approximately $2.7 million, and the Malkin Group, which includes Anthony E. Malkin, Peter L. Malkin and their related parties and affiliates, directly and/or indirectly received approximately $44.9 million, in each case consisting of a combination of shares of our Class B common stock and Series PR operating partnership units, and the estate of Leona M. Helmsley (a member of affiliates of our predecessor and of the owners of the option properties) directly and/or indirectly received approximately $92.4 million in cash. The 1400 Property was acquired for approximately $310.0 million, consisting of assumption of existing mortgage debt, cash and shares of our Class A and Class B common stock and our operating partnership’s Series PR operating partnership units. In connection with the acquisition of the 1400 Property, Anthony E. Malkin directly and/or indirectly received approximately $23.3 million, and the Malkin Group, which includes Anthony E. Malkin, Peter L. Malkin and their related parties and affiliates, directly and/or indirectly received approximately $23.5 million, in each case consisting of a combination of shares of our Class B common stock and Series PR operating partnership units, and the estate of Leona Helmsley directly and/or indirectly received approximately $56.6 million in cash. The purchase price for each of the option properties was based on an appraisal by independent third parties utilizing the appraisal process set forth in the option agreements. As part of the option agreements, we agreed that Anthony E. Malkin, our Chairman and Chief Executive Officer, would not participate in the negotiations and valuation process on our behalf. Our Chairman Emeritus, Peter L. Malkin, also agreed not to participate in the process. In addition our Board of Directors appointed a special committee consisting of independent members of such Board to review the appraisal process on its behalf. The independent members of our Board of Directors unanimously approved the price and terms of the acquisition of interests in each of the option properties. The purchase price was payable in a combination of cash, shares of our common stock and operating partnership units, but the estate of Leona M. Helmsley (a member of affiliates of our predecessor and of the owners of option properties) received all cash. Reference is made to Note 3.

In connection with the closing of the transaction, we entered into a registration rights agreement covering the resale of all shares of our Class A common stock issued in connection with the transactions, and all shares of our Class A common stock that may be issued upon redemption of Series PR operating partnership units or upon conversion of our Class B common stock issued in connection with the transactions. To satisfy our obligation under the registration rights agreement, we registered the issuance of the shares of Class A common stock that may be issued upon redemption of Series PR operating partnership units or upon conversion of Class B common stock as part of the automatically effective shelf registration statement that we filed on October 7, 2014. Additionally, the shares of Class A common stock issued to the Malkin family in connection with the transactions are subject to the demand and piggy-back rights that the Malkin family has under the registration rights agreement we entered into in connection with the consolidation and initial public offering of our Class A common stock. See “-Registration Rights” above.

Excluded Properties and Businesses

Our portfolio is partially comprised of all of our predecessor’s Manhattan and greater New York metropolitan area office and retail assets in which it held a controlling interest and other metropolitan area office properties in which it had a non-controlling interest. The Malkin Group, including Anthony E. Malkin, our Chairman and Chief Executive Officer, owns non-controlling interests in, and Anthony E. Malkin and Peter L. Malkin control the general partners or managers of, the entities that own interests in seven multi-family properties, six net leased retail properties, (including one single tenant retail property in Greenwich, Connecticut), and a parcel that is being developed for residential use. The Malkin Group also owns non-controlling interests in one Manhattan office property, two Manhattan retail properties and several retail properties outside of Manhattan, none of which were contributed to us in the formation transactions. We refer to the non-controlling interests described above collectively as the excluded properties. In addition, the Malkin Group owns interests in two mezzanine and senior equity funds, three industrial funds, and five residential property managers, none of which were contributed to us in the formation transactions, and which we refer to collectively as the excluded businesses. The Malkin Group owns certain non-real estate family investments that were not contributed to us in the formation transactions. Other than the Greenwich retail property, we do not believe that the excluded properties or the excluded businesses are consistent with our portfolio geographic or property type composition, management or strategic direction.

F-44

Pursuant to management and/or service agreements with the owners of interests in those excluded properties and services agreements with the five residential property managers and the managers of certain other excluded businesses which historically were managed by affiliates of our predecessor, we are designated as the manager of the excluded properties and will provide services to the owners of certain of the excluded properties and the five residential property managers and provide services and access to office space to the existing managers of the other excluded businesses. As the manager or service provider, we are paid a management or other fee with respect to those excluded properties and excluded businesses where our predecessor had previously received a management fee on the same terms as the fee paid to our predecessor, and reimbursed for our costs in providing the management and other services to those excluded properties and businesses where our predecessor had not previously received a management fee. ESRT's management of the excluded properties and provision of services to the five residential property managers and the existing managers of the other excluded businesses represent a minimal portion of our overall business. There is no established time period in which we will manage such properties or provide services to the owners of certain of the excluded properties and the five residential property managers and provide services and access to office space to the existing managers of the other excluded businesses and Peter L. Malkin and Anthony E. Malkin expect to sell certain of these properties or unwind certain of these businesses over time. We are not precluded from acquiring all or certain interests in the excluded properties or businesses. If we were to attempt any such acquisition, we anticipate that Anthony E. Malkin, ESRT's Chairman and Chief Executive Officer, will not participate in the negotiation process on our behalf with respect to our potential acquisition of any of these excluded properties or businesses and the approval of a majority of ESRT's independent directors will be required to approve any such acquisition.

Reimbursement of Pre-Closing Transaction Costs

As part of the contribution and option agreements, $103.8 million of expenses incurred in connection with the formation transactions and the Offering were reimbursed from the proceeds of the Offering. The existing entities and our predecessor's management companies declared final distributions, inclusive of reimbursement of these expenses, to the investors in such entities, including members of our senior management team and certain of our directors, in an amount of approximately $180.0 million in the aggregate, and of which $38.9 million was paid to the Malkin Group, including Peter L. Malkin and Anthony E. Malkin, in accordance to their ownership interests in each applicable existing entity and predecessor management company.

Guarantees

The mortgage loan on First Stamford Place is guaranteed and/or indemnified by Peter L. Malkin and Anthony E. Malkin. We entered into an indemnification agreement with Peter L. Malkin and Anthony E. Malkin pursuant to which we are obligated to indemnify Peter L. Malkin and Anthony E. Malkin for any amounts paid by them under the guarantees and/or indemnities with respect to the First Stamford Place mortgage loan.

Other Services

Services are and were provided by us or our predecessor to affiliates of the sponsors. These affiliates were related parties because beneficial interests were or are held, directly or indirectly, by the sponsors, their affiliates and their family members.

During the years ended December 31, 2015, 2014 and 2013, we or our predecessor engaged in various transactions with affiliates. These transactions are reflected in our and our predecessor's consolidated statements of operations as third-party management and other fees and the unpaid balances are reflected in the due from affiliated companies on our consolidated balance sheets (See Note 7).

Other

We are reimbursed at allocable cost for 647 square feet of shared office space, equipment, and administrative support, as was done prior to our formation, and we receive rent generally at market rental rate for 3,074 square feet of leased space, from entities affiliated with Anthony E. Malkin at one of our properties aggregating $0.2 million, $0.1 million and $1.1 million, for the years ended December 31, 2015, 2014 and 2013, respectively. In each case the space is expected to be temporary, and such affiliate has the right to cancel such lease without special payment on 90 days’ notice.

13. Income Taxes

TRS Holdings and Observatory TRS are taxable entities and their consolidated provision for income taxes consisted of the following for the years ended December 31, 2015 and 2014 and the period October 7, 2013 through December 31, 2013 (amounts in thousands):

F-46



	For the Year Ended December 31,						Period from October 7, 2013 through December 31, 2013
	2015			2014			Period from October 7, 2013 through December 31, 2013
Current:
Federal	$	(2,714	)	$	(3,253	)	$	844
State and local	(1,502		)	(1,792		)	281
Total current	(4,216		)	(5,045		)	1,125
Deferred:
Federal	169			247			—
State and local	98			143			—
Total deferred	267			390			—
Income tax (expense) benefit	$	(3,949	)	$	(4,655	)	$	1,125

The effective income tax rate is 44.7%, 44.3% and 45.3% for the years ended December 31, 2015 and 2014 and the period from October 7, 2013 through December 31, 2013, respectively. The actual tax provision differed from that computed at the federal statutory corporate rate as follows (amounts in thousands):



	For the Year Ended December 31,						Period from October 7, 2013 through December 31, 2013
	2015			2014			Period from October 7, 2013 through December 31, 2013
Federal tax (expense) benefit at 34% statutory rate	$	(3,003	)	$	(3,576	)	$	844
State income taxes, net of federal benefit	(946		)	(1,079		)	281
Income tax (expense) benefit	$	(3,949	)	$	(4,655	)	$	1,125

The income tax effects of temporary differences that give rise to deferred tax assets are presented below as of December 31, (amounts in thousands):



	2015		2014		2013
Deferred tax assets:
Deferred revenue on unredeemed observatory admission ticket sales	$	267	$	390	$	—
Loss carryforwards	—		—		1,125
Total deferred tax assets	267		390		1,125
Deferred tax liabilities:
Total deferred tax liabilities	—		—		—
Total	$	267	$	390	$	1,125

Deferred tax assets at December 31, 2015 and 2014, respectively, are attributable to the inclusion of deferred revenue on Observatory admission ticket sales not redeemed at year-end in determining income for tax reporting purposes. No valuation allowance has been recorded against the deferred tax asset because the Company believes that the deferred tax asset will, more likely than not, be realized. This determination is based on the Observatory TRS’s anticipated future taxable income and the reversal of the deferred tax asset.

Deferred tax asset at December 31, 2013 is attributable to the Observatory TRS’s loss during the period from October 7, 2013 through December 31, 2013 as a result of increased percentage rent. Percentage rent is based on gross receipts and the highest percentage is reached in the fourth quarter. The loss was fully absorbed by the Observatory TRS’s profit in 2014. At December 31, 2015 and 2014, the TRS entities have no amount of unrecognized tax benefits.

For tax years 2015, 2014 and 2013, the United States federal and state tax returns are open for examination.

14. Segment Reporting

F-47

We have identified two reportable segments: (1) Real Estate and (2) Observatory. Our real estate segment includes all activities related to the ownership, management, operation, acquisition, repositioning and disposition of our real estate assets. Our observatory segment operates the 86th and 102nd floor observatories at the Empire State Building. These two lines of businesses are managed separately because each business requires different support infrastructures, provides different services and has dissimilar economic characteristics such as investments needed, stream of revenues and different marketing strategies. We account for intersegment sales and transfers as if the sales or transfers were to third parties, that is, at current market prices. We include our historical construction operation in "Other," and it includes all activities related to providing construction services to tenants and to other entities within and outside our company. As of March 27, 2015, we no longer solicited new business for our construction management business. We completed all projects that were in progress.

The following tables provide components of segment profit for each segment for the years ended December 31, 2015, 2014 and 2013, as reviewed by management (amounts in thousands):
