Empire State Realty Trust, Inc.
Notes to Condensed Consolidated Financial Statements
(unaudited)
1. Description of Business and Organization
    As used in these condensed consolidated financial statements, unless the context otherwise requires, “we,” “us,” “our,” the “company,” and "ESRT" mean Empire State Realty Trust, Inc. and its consolidated subsidiaries.
    We are a self-administered and self-managed real estate investment trust ("REIT") that owns, manages, operates, acquires and repositions office and retail properties in Manhattan and the greater New York metropolitan area.
    As of JuneSeptember 30, 2021, our total portfolio contained 10.1 million rentable square feet of office and retail space. We owned 14 office properties (including 3 long-term ground leasehold interests) encompassing approximately 9.4 million rentable square feet of office space. NaN of these properties are located in the midtown Manhattan market and aggregate approximately 7.6 million rentable square feet of office space, including the Empire State Building. Our Manhattan office properties also contain an aggregate of approximately 0.5 million rentable square feet of retail space on their ground floor and/or contiguous levels. Our remaining 5 office properties are located in Fairfield County, Connecticut and Westchester County, New York, encompassing in the aggregate approximately 1.8 million rentable square feet. The majority of square footage for these 5 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 0.4 million rentable square foot office building and garage. As of JuneSeptember 30, 2021, our portfolio included 4 standalone retail properties located in Manhattan and 2 standalone retail properties located in the city center of Westport, Connecticut, encompassing approximately 0.2 million rentable square feet in the aggregate.
     We were organized as a Maryland corporation on July 29, 2011 and commenced operations upon completion of our initial public offering and related formation transactions on October 7, 2013. Our operating partnership, Empire State Realty OP, L.P. (the "Operating Partnership"), holds substantially all of our assets and conducts substantially all of our business. As of JuneSeptember 30, 2021, we owned approximately 60.7%60.8% of the aggregate operating partnership units in the Operating Partnership. We, as the sole general partner in the Operating Partnership, have responsibility and discretion in the management and control of the Operating Partnership, and the limited partners in the Operating Partnership, in such capacity, have no authority to transact business for, or participate in the management activities of, the Operating Partnership. Accordingly, the Operating Partnership has been consolidated by us. We elected to be taxed as a REIT and operate in a manner that we believe allows us to qualify as a REIT for federal income tax purposes commencing with our taxable year ended December 31, 2013.
2. Summary of Significant Accounting Policies
    There have been no material changes to the summary of significant accounting policies included in the section entitled "Summary of Significant Accounting Policies" in our December 31, 2020 Annual Report on Form 10-K.

Basis of Quarterly Presentation and Principles of Consolidation
    The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), for interim financial information, and with the rules and regulations of the Securities and Exchange Commission (the "SEC"). Accordingly, certain information and footnote disclosures required by GAAP for complete financial statements have been condensed or omitted in accordance with such rules and regulations. In the opinion of management, all adjustments and eliminations (including intercompany balances and transactions), consisting of normal recurring adjustments, considered necessary for the fair presentation of the financial statements have been included.
    The results of operations for the periods presented are not necessarily indicative of the results that may be expected for the corresponding full years. These financial statements should be read in conjunction with the financial statements and accompanying notes included in the financial statements for the year ended December 31, 2020 contained in our Annual Report on Form 10-K. We do not consider our business to be subject to material seasonal fluctuations, except that our observatory business is subject to tourism seasonality and currently impacted by the Coronavirus 19 ("COVID-19") pandemic. Historically prior to the outbreak of the COVID-19 pandemic, approximately 16.0% to 18.0% of our annual observatory revenue was
9









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 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.  For variable interest entities ("VIE"), we consolidate the entity if we are deemed to have a variable interest in the entity and through that interest we are deemed 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. The Operating Partnership is a variable interest entity of our company, Empire State Realty Trust, Inc.  As the Operating Partnership is already consolidated in the financial statements of Empire State Realty Trust, Inc., the identification of this entity as a variable interest entity has no impact on our consolidated financial statements.
    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 condensed consolidated balance sheets and in the condensed consolidated statements of operations by requiring earnings and other comprehensive income to be attributed to controlling and non-controlling interests.
Accounting Estimates
    The preparation of the condensed 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, right of use assets and other long-lived and indefinite lived assets, estimate of tenant expense reimbursements, valuation of the allowance for doubtful accounts, and valuation of derivative instruments, ground lease liabilities, senior unsecured notes, mortgage notes payable, unsecured term loan and revolving credit facilities, 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.
Recently Issued or Adopted Accounting Standards
    During April 2020, the Financial Accounting Standards Board ("FASB") staff issued a question and answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. Under existing lease guidance, the entity would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant, which would be accounted for under the lease modification framework, or if a lease concession was under the enforceable rights and obligations that existed in the original lease, which would be accounted for outside the lease modification framework. The Lease Modification Q&A provides entities with the option to elect to account for lease concessions as though the enforceable rights and obligations existed in the original lease. This election is only available when total cash flows resulting from the modified lease are substantially similar to the cash flows in the original lease.
    During March 2020, the FASB issued Accounting Standards Update ("ASU") 2020-04, Reference Rate Reform (Topic 848). ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. During the first quarter 2020, we elected to apply the hedge accounting expedients related to probability and the
10









assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. We continue to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur.

    Rental revenue related to the amortization of below-market leases, net of above-market leases, was $0.7$4.2 million and $1.4$0.7 million for the three months ended JuneSeptember 30, 2021 and 2020, respectively, and $1.4$5.6 million and $2.3$3.0 million for the sixnine months ended JuneSeptember 30, 2021 and 2020, respectively.
     As of JuneSeptember 30, 2021, we had goodwill of $491.5 million. Goodwill was allocated $227.5 million to the observatory reportable segment and $264.0 million to the real estate reportable segment.
    In compliance with the requirements of authorities, we closed the Empire State Building Observatory on March 16, 2020 due to the COVID-19 pandemic and it remained closed until the 86th floor observation deck was reopened on July 20, 2020. The 102nd observation deck was reopened on August 24, 2020. The closure of our Observatory and subsequent reopening under international, national, and local travel restrictions and quarantines caused us during the quarter to choose to perform an impairment test related to goodwill. We engaged a third-party valuation consulting firm to perform the valuation process. The analysis used a combination of the discounted cash flow method (a form of the income approach) utilizing Level 3 unobservable inputs and the guideline company method (a form of the market approach). Significant assumptions under the former included revenue and cost projections, weighted average cost of capital, long-term growth rate and income tax considerations while the latter included guideline company enterprise values, revenue multiples and control premium rates. Our
11


methodology to review goodwill impairment, which included a significant amount of judgment and estimates, provided a
11









reasonable basis to determine whether impairment had occurred. Based upon the results of the goodwill impairment test of the standalone Observatory reporting unit, which is after the intercompany rent expense paid to the Real Estate reporting unit, we determined that the fair value of the Observatory reporting unit exceeded its carrying value by less than 15.0%.  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.  We will continue to assess the impairment of the Observatory reporting unit goodwill going forward and that continued assessment may again utilize a third-party valuation consulting firm.

     Additionally, as described more fully in the Q1 2021 10-Q, we have outstanding a senior unsecured term loan facility (the "Term Loan Facility") that we entered into on March 19, 2020 with Wells Fargo Bank, National Association, as administrative agent, and the other lenders party thereto. The Term loan Facility is in the original principal amount of $175.0$175.0 million and matures on December 31, 2026.

6. 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 obligations. As of JuneSeptember 30, 2021, the fair value of the derivative in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to the agreement was $6.2$4.9 million. If we had breached any of these provisions at JuneSeptember 30, 2021, we could have been required to settle our obligation under the agreement at its termination value of $6.2$4.9 million.

    As of JuneSeptember 30, 2021 and December 31, 2020, we had an interest rate LIBOR swap with an aggregate notional value of $265.0 million and $265.0 million, respectively.million. The notional value does not represent exposure to credit, interest rate or market risks. As of JuneSeptember 30, 2021 and December 31, 2020, the fair value of our derivative instrument amounted to $(6.2)$(4.9) million and $(8.8) million, respectively, which is included in accounts payable and accrued expenses on the condensed consolidated balance sheets. This interest rate swap has been designated as a cash flow hedge and hedges the variability in future cash flows associated with our existing variable-rate term loan facilities.

    As of JuneSeptember 30, 2021 and 2020, our cash flow hedge is deemed highly effective and a net unrealized gain (loss) of $2.8 million and $0.6$2.9 million for the three months ended JuneSeptember 30, 2021 and 2020, respectively, and a net unrealized gain (loss) of $5.7$8.5 million and $(16.3)$(13.4) million for the sixnine months ended JuneSeptember 30, 2021 and 2020, respectively, relating to both active and terminated hedges of interest rate risk, are reflected in the condensed consolidated statements of comprehensive income (loss). Amounts reported in accumulated other comprehensive income (loss)loss related to derivatives will be reclassified to interest expense as interest payments are made on the debt. We estimate that $(11.5)$(11.0) million net loss of the current balance held in accumulated other comprehensive income (loss)loss will be reclassified into interest expense within the next 12 months.

Fair Valuation

    The estimated fair values at JuneSeptember 30, 2021 and December 31, 2020 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 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 our derivatives were classified as Level 2 of the fair value hierarchy.

    The fair value of our mortgage notes payable, senior unsecured notes - Series A, B, C, D, E, F, G and H - unsecured term loan facilities and unsecured revolving credit facility 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 toby us.

    The following tables summarize the carrying and estimated fair values of our financial instruments as of JuneSeptember 30, 2021 and December 31, 2020 (amounts in thousands):

    Disclosure about the fair value of financial instruments is based on pertinent information available to us as of JuneSeptember 30, 2021 and December 31, 2020. 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.

7. Leases
Lessor    
    We lease various spaces to tenants over terms ranging from one to 21 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 JuneSeptember 30, 2021 and 2020 condensed consolidated statements of operations as rental revenue.

Rental revenue includes fixed and variable payments. Fixed payments primarily relate to base rent and variable payments primarily relate to tenant expense reimbursements for certain property operating costs. The components of rental revenue for the three and sixnine months ended JuneSeptember 30, 2021 and 2020 are as follows (amounts in thousands):

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.
Lessee
    We determine if an arrangement is a lease at inception. Our operating lease agreements relate to 3 ground lease assets and are reflected in right-of-use assets of $29.0$28.9 million and lease liabilities of $29.0$28.9 million in our consolidated balance sheets as of JuneSeptember 30, 2021. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Variable lease payments are excluded from the right-of-use assets and lease liabilities and are recognized in the period in which the obligation for those payments is incurred.
    We make payments under ground leases related to 3 of our properties.    The ground leases are due to expire between the years 2050 and 2077, inclusive of extension options, and have no variable payments or residual value guarantees. As our leases do not provide an implicit rate, we determined our incremental borrowing rate based on information available at the date of adoption of ASU No. 2016-02, Leases (Topic 842), in determining the present value of lease payments. The weighted average incremental borrowing rate used to calculate the right-of-use assets and lease liabilities as of JuneSeptember 30, 2021 was 4.5%. Rent expense for lease payments related to our operating leases is recognized on a straight-line basis over the non-cancellable term of the leases. The weighted average remaining lease term as of JuneSeptember 30, 2021 was 48.948.6 years.

    As of JuneSeptember 30, 2021, the following table summarizes our future minimum lease payments discounted by our incremental borrowing rates to calculate the lease liabilities of our leases (amounts in thousands):

8. Commitments and Contingencies
Legal Proceedings
    Except as described below, as of JuneSeptember 30, 2021, 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 condensed consolidated financial position, operating results or liquidity.
    As previously disclosed, in October 2014, 12 former investors (the "Claimants") in Empire State Building Associates L.L.C. (“ESBA”), which prior to the initial public offering of our company (the "Offering"), owned the fee title to the Empire State Building, filed an arbitration with the American Arbitration Association against Peter L. Malkin, Anthony E. Malkin,
17









Thomas N. Keltner, Jr., and our subsidiary ESRT MH Holdings LLC, the former supervisor of ESBA (the "Respondents"). The statement of claim (also filed later in federal court in New York for the expressed purpose of tolling the statute of limitations) alleges breach of fiduciary duty and related claims in connection with the Offering and formation transactions and seeks monetary damages and declaratory relief. Claimants had opted out of a prior class action bringing similar claims that was settled with court approval. Respondents filed an answer and counterclaims. In March 2015, the federal court action was stayed on consent of all parties pending the arbitration. Arbitration hearings started in May 2016 and concluded in August 2018. On August 26, 2020, the arbitration panel issued an award that denied all Claimants’ claims with one exception, on which it awarded Claimants approximately $1.2 million, inclusive of seven years of interest through October 2, 2020. This amount was recorded as an IPO litigation expense in the consolidated statement of operations for the year ended December 31, 2020.
Respondents believe that such award in favor of the Claimants is entirely without merit and have sought to vacate that portion of the award. On September 27, 2021, the court denied Respondents' motion to vacate and entered judgement in the aforementioned amount, inclusive of accumulated interest. Respondents are considering their options with respect to that ruling. In addition, certain of the Claimants in the federal court action sought to pursue claims in that case against Respondents. Respondents believe that any such claims are meritless. The magistrate judge assigned to the action has issued a Report and Recommendation rejecting Claimants’ claims; the district judge will decide whether to adopt the Report and Recommendation.

     Pursuant to indemnification agreements which were made with our directors, executive officers and chairman emeritus as part of our formation transactions, Anthony E. Malkin, Peter L. Malkin and Thomas N. Keltner, Jr. have defense and indemnity rights from us with respect to this arbitration.
Unfunded Capital Expenditures

    At JuneSeptember 30, 2021, we estimate that we will incur approximately $89.1$85.2 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 and cash equivalents, restricted cash, short-term investments, tenant and other receivables and deferred rent receivables. At JuneSeptember 30, 2021, we held on deposit at various major financial institutions cash and cash equivalents and restricted cash balances in excess of amounts insured by the Federal Deposit Insurance Corporation.
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 JuneSeptember 30, 2021, 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 JuneSeptember 30, 2021, 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 financial condition, results of operations or liquidity. However, we cannot be certain that we have identified all environmental liabilities
18









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.
18


Insurance Coverage
    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.
9. Equity
Shares and Units
    An operating partnership unit of the Operating Partnership ("OP Unit") and a share of our common stock have essentially the same economic characteristics as they receive the same per unit profit distributions of the Operating Partnership. On the one-year anniversary of issuance, an OP Unit may be tendered for redemption for cash; however, we have sole and absolute discretion, and sufficient authorized common stock, to exchange OP Units for shares of common stock on a 1-for-one basis instead of cash.
    On May 16, 2019, the Empire State Realty Trust, Inc. Empire State Realty OP, L.P. 2019 Equity Incentive Plan (“2019 Plan”) was approved by our shareholders.  The 2019 Plan provides for grants to directors, employees and consultants of our company and operating partnership, including options, restricted stock, restricted stock units, stock appreciation rights, performance awards, dividend equivalents and other equity-based awards.  An aggregate of approximately 11.0 million shares of our common stock are authorized for issuance under awards granted pursuant to the 2019 Plan. We will not issue any new equity awards under the First Amended and Restated Empire State Realty Trust, Inc. and Empire State Realty OP, L.P. 2013 Equity Incentive Plan ("2013 Plan", and collectively with the 2019 Plan, "the Plans"). The shares of Class A common stock underlying any awards under the 2019 Plan and the 2013 Plan that are forfeited, canceled or otherwise terminated, other than by exercise, will be added back to the shares of Class A common stock available for issuance under the 2019 Plan. Shares tendered or held back upon exercise of a stock option or settlement of an award under the 2019 Plan or the 2013 Plan to cover the exercise price or tax withholding and shares subject to a stock appreciation right that are not issued in connection with the stock settlement of the stock appreciation right upon exercise thereof, will not be added back to the shares of Class A common stock available for issuance under the 2019 Plan. In addition, shares of Class A common stock repurchased on the open market will not be added back to the shares of Class A common stock available for issuance under the 2019 Plan.
    Long-term incentive plan ("LTIP") units are a special class of partnership interests in the Operating Partnership. Each LTIP unit awarded will be deemed equivalent to an award of one share of stock under the Plans, reducing the availability for other equity awards on a one-for-one1-for-one basis.
    The vesting period for LTIP units, if any, will be determined at the time of issuance. Under the terms of the LTIP units, the Operating Partnership 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 OP unitholders. Subject to any agreed upon exceptions, once vested and having achieved parity with OP unitholders, LTIP units are convertible into OP Units in the Operating Partnership on a one-for-one1-for-one basis.
     LTIP units subject to time-based vesting, whether vested or not, receive the same per unit distributions as OP units, which equal per share dividends (both regular and special) on our common stock. LTIP units subject to market-based vesting receive 10% of such distributions currently, unless and until such LTIP units are earned based on performance, at which time they will receive the accrued and unpaid 90% and will commence receiving 100% of such distributions thereafter.

Stock and Publicly Traded Operating Partnership Unit Repurchase Program
    Our Board of Directors reauthorized the repurchase of up to $500 million of our Class A common stock and the Operating Partnership’s Series ES, Series 250 and Series 60 operating partnership units through December 31, 2021. Under the program, we may purchase our Class A common stock and the Operating Partnership’s Series ES, Series 250 and Series 60 operating partnership units in accordance with applicable securities laws from time to time in the open market or in privately negotiated transactions. The timing, manner, price and amount of any repurchases will be determined by us at our discretion and will be subject to stock price, availability, trading volume and general market conditions. The authorization does not obligate us to acquire any particular amount of securities, and the program may be suspended or discontinued at our discretion without prior notice.

Incentive and Share-Based Compensation
    The Plans provide for grants to directors, employees and consultants consisting of stock options, restricted stock, dividend equivalents, stock payments, performance shares, LTIP units, stock appreciation rights and other incentive awards. An aggregate of 11.0 million shares of our common stock is authorized for issuance under awards granted pursuant to the 2019 Plan, and as of JuneSeptember 30, 2021, 7.7 million shares of common stock remain available for future issuance.
Annually,In August 2021, we make grants ofgranted LTIP units to our non-employee directors under the 2019 Plan. In 2021, eachPlan to Christina Chiu, our Executive Vice President and Chief Financial Officer, consisting of our directors received 60% of their $200,000 annual base retainer in the form of equity vesting ratably over four years, and could elect to receive the remaining 40% of such base retainer (i) in cash at the face value of the award, (ii) in immediately vesting equity at the face value of the award, or (iii) in equity vesting ratably over three years at 120% of the face amount.Each director could elect to receive any equity portion of the base retainer in either (i) LTIP units or (ii) restricted shares of our Class A common stock. In accordance with each director's election, we granted a total of 126,7138,772 LTIP units that are subject to time-based vesting with fair market values of $1.4 million and no restricted shares. The LTIP units vest ratably over three or four years from the date of the grant, based on grantee election, subject generally to the director's continued service on our Board of Directors. We also granted 8,324 LTIP units that are subject to immediate vesting with fair market values of $0.1 million.
    In COVID-19 disrupted markets which created unusual volatility in our share price during the first quarter of 2020, the26,930 LTIP units that are subject to market-based vesting, were undervalued on initial appraisal, and the resulting number of LTIP units issued in March 2020 was reduced on final appraisal to match the original Board-approved dollar value. Thus, in June
20


2020, we reduced the grants of LTIP units that are subject to market-based vesting which were awarded to executive officers and certain other employees by 666,933 LTIP units with fair market values of $2.8$0.075 million for the time-based vesting awards and 99,630$0.15 million for the market-based vesting awards. The awards subject to time-based vesting vest ratably over four years from January 1, 2021, subject generally to her continued employment. The first installment vests on January 1, 2022 and the remainder will vest thereafter in 3 equal annual installments. The vesting of the LTIP units subject to market-based vesting is based on the achievement of relative total stockholder return hurdles over a three-year performance period, commencing on January 1, 2021. Following the completion of the three-year performance period, our compensation and human capital committee will determine the number of LTIP units to which she is entitled based on our performance relative to the performance hurdles set forth in the LTIP unit award agreement entered into in connection with fair market values of $0.5 million, respectively. Such volatility was not materialthe award grant. These units then vest in 2021,2 installments, with the first installment vesting on January 1, 2024 and no such adjustment was needed in 2021.the second installment vesting on January 1, 2025, subject generally to her continued employment on those dates.
    Share-based compensation for time-based equity awards 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 shorter of (i) the stated vesting period, which is generally three, four or five years, or (ii) the period from the date of grant to the date the employee becomes retirement eligible, which may occur upon grant. An employee is retirement eligible when the employee attains the (i) age of 65 and (ii) the date on which the employee has first completed ten years of continuous service with us or our affiliates. During the second quarter of 2020, the Board approved changing the definition of retirement age from 60 to 65 starting with the grant awards issued in March 2020 under the 2019 Plan. Share-based compensation for market-based equity awards 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 three or four years depending on retirement eligibility.
    For the market-based LTIP units, the fair value of the awards was estimated using a Monte Carlo Simulation model and discounted for the restriction period during which the LTIP units cannot be redeemed or transferred and the uncertainty regarding if, and when, the book capital account of the LTIP units will equal that of the common units.  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 unit awards that are time-based, the fair value of the awards was estimated based on the fair value of our stock at the grant date discounted for the restriction period during which the LTIP units cannot be redeemed or transferred and the uncertainty regarding if, and when, the book capital account of the LTIP units will equal that of the common units.  For restricted stock awards, we estimate the stock compensation expense based on the fair value of the stock at the grant date.
    LTIP units and restricted stock issued during the sixnine months ended JuneSeptember 30, 2021 were valued at $19.8$20.0 million. The weighted average per unit or share fair value was $8.55$8.52 for grants issued in 2021. The per unit or share granted in 2021 was estimated on the respective dates of grant using the following assumptions: an expected life from 2.0 to 5.3 years, a dividend rate of 2.60%, a risk-free interest rate from 0.12% to 0.32%, and an expected price volatility from 36.0% to 53.0%. No other stock options, dividend equivalents, or stock appreciation rights were issued or outstanding in 2021.

11. Segment Reporting
    We have identified 2 reportable segments: (1) real estate and (2) observatory. Our real estate segment includes all activities related to the ownership, management, operation, acquisition, redevelopment, repositioning and disposition of our traditional real estate assets. Our observatory segment includes the operation of the 86th and 102nd floor observatories at the Empire State Building. These 2 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 marketing strategies. We account for intersegment sales and rent as if the sales or rent were to third parties, that is, at current market prices.

The following tables provide components of segment net income (loss) for each segment for the three and sixnine months ended JuneSeptember 30, 2021 and 2020 (amounts in thousands):

Overview
    We are a self-administered and self-managed REIT that owns, manages, operates, acquires and repositions office and retail properties in Manhattan and the greater New York metropolitan area.
Highlights for the three months ended JuneSeptember 30, 2021 included:

Incurred net incomeloss attributable to the Company of $2.1$7.0 million and achieved Core Funds From Operations ("Core FFO") of $48.8$55.3 million.
Same-Store Property Cash NOI,Net Operating Income, excluding lease termination fees, was down 6.0%5.7% from the secondthird quarter of 2020 primarily driven by a reduction in revenues due to reduced occupancy, third quarter 2021 revenue from Global Brands Group treated partially as rental revenue and partially as lease termination income and write-offs taken over the one-year period.
Empire State Building Observatory revenue for the secondthird quarter 2021 increased to $8.4$12.8 million, from $2.6$8.4 million in the firstsecond quarter 2021 as visitation continued to ramp up. Observatory net operating income was $3.1$6.4 million for the third quarter 2021, which is the second consecutive quarter of positive NOI since the onset of the COVID-19 pandemic and more than double second quarter 2021.earnings contribution.
Realized lease termination fees were $3.3$11.3 million. In keeping with historical practice, we include lease termination fees when calculating FFO and Core FFO.
Signed 3534 new, renewal, and expansion leases, representing a total of 190,838268,055 rentable square feet. This includes 21 leases totaling 212,301 rentable square feet in the Manhattan office portfolio.
Collected 95% of secondthird quarter 2021 total billings, stable and in line with 95% for office tenants and 91% for retail tenants.recent quarters.

Reinstated quarterly dividend at $0.035 per share forIn the secondthird quarter of 2021, which is one quarter earlier than previously announced, driven by confidence in the New York City recovery and improvement in our results and liquidity.
From January 1, 2021 and through July 27,October 26, 2021, wethe Company repurchased $3.5$6.5 million of ourits common stock at a weighted average price of $9.22$10.41 per share. This brings the cumulative total, since the stock repurchase program began on March 5, 2020 through August 5,October 26, 2021, to $147.2$153.8 million at a weighted average price of $8.34$8.41 per share.
    As of JuneSeptember 30, 2021, 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 interests) encompassing approximately 9.4 million rentable square feet of office space. Nine of these properties are located in the midtown Manhattan market and aggregate approximately 7.6 million rentable square feet of office space, including the Empire State Building. Our Manhattan office properties also contain an aggregate of approximately 0.5 million 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 in the aggregate approximately 1.8 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 0.4 million rentable square foot office building and garage. Our portfolio includes four standalone retail properties located in Manhattan and two standalone retail properties located in the city center of Westport, Connecticut, encompassing approximately 0.2 million rentable square feet in the aggregate.
    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 are a separate reporting segment. Our observatory operations are subject to regular patterns of tourist activity in Manhattan and currently impacted by the COVID-19 pandemic. Historically, prior to the outbreak of the COVID-19 pandemic, approximately 16.0% to 18.0% of our annual observatory revenue 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. On March 16, 2020, we complied with governmental mandates regarding the closing of non-essential businesses in response to the COVID-19 pandemic and closed the Empire State Building Observatory. The Observatory reopened on July 20, 2020.

    We have undertaken a comprehensive redevelopment and repositioning strategy of our Manhattan office properties. This strategy is designed to improve the overall value and attractiveness of our properties and has 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. These improvements 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. 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 as well as 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. From 2002 through JuneSeptember 30, 2021, we have invested a total of approximately $956.4$959.7 million (excluding tenant improvement costs and leasing commissions) in our Manhattan office properties pursuant to this program. We intend to fund capital improvements through a combination of operating cash flow, cash on hand, and borrowings.
    The Greater New York Metropolitan Area office market is soft, and we compete with properties that have been redeveloped recently or have planned redevelopment.  We have spent approximately $37.3$39.3 million over 2018 through 2021 on these well-maintained and our well-located properties’ common areas and amenities to ensure competitiveness and protect our market position.
     As of JuneSeptember 30, 2021, we had total debt outstanding of approximately $2.1 billion, with a weighted average interest rate of 3.9%, and a weighted average maturity of 7.77.4 years. 94.2% of our total debt outstanding is fixed-rate indebtedness. Excluding principal amortization, we had no outstanding debt maturing until November 2024. As of JuneSeptember 30, 2021, we had cash and cash equivalents of $540.6$582.2 million. Our consolidated net debt to total market capitalization was 31.4%34.7% as of JuneSeptember 30, 2021.
Impact of COVID-19

    In March 2020, the outbreak of the novel COVID-19 was recognized as a pandemic by the World Health Organization. The spread of COVID-19 has created a global public health crisis that has resulted in unprecedented economic, social and political uncertainty, volatility and disruption in the United States and globally. We have taken the following actions in response to the impact of the COVID-19 pandemic on our business.

Liquidity

We currently hold $540.6$582.2 million in cash and cash equivalents on our balance sheet and have $850 million undrawn capacity under our unsecured revolving credit facility. Our $850 million unsecured revolving credit facility matures in March 2025 and has two six-month extension options, subject to certain conditions.

Property Operations

31









All of our office buildings have remained open during the COVID-19 pandemic. We have scaled back certain building operations in cleaning, security, lobby concierge and recurring maintenance, which reduced costs until buildings are repopulated. A portion of the reduction in operating expenses was offset by a reduction in tenant expense recoveries.

31


Our operations team worked diligently to develop and implement plans for tenants' reoccupation of our buildings to ensure a safe, clean and healthy work environment. These plans involved staff reassigned to screen tenants and visitors, changes to cleaning and maintenance standards, and changes to building operations for access by tenants and their guests.

Despite the challenge of the uncertain near-term environment, we continue to believe in the long-term demand for office space. We believe many tenants have acknowledged the challenges, inequities, and worries about divided workplaces between home and office work, the challenges with onboarding new employees and miss the connectivity and productivity that an office environment provides.
Leasing
    The economic uncertainty relating to the COVID-19 pandemic has slowed the pace of our leasing activity and could result in higher vacancy than we otherwise would have experienced, a longer amount of time to fill vacancies, increased concessions and potentially lower rental rates. In addition, potential work from home could negatively impact the office leasing market. As of JuneSeptember 30, 2021, our portfolio was 88.2%86.5% leased, including signed leases not yet commenced, with 4.9%2.3% subject to leases scheduled to expire in 2021 and 5.6%5.5% subject to leases scheduled to expire in 2022.

New leasing activity was impacted during 2020 by the COVID-19 pandemic and shelter-in-place rules that were in effect for much of the period. On June 15, 2021, New York State ended pandemic-linked restrictions given the broad-based distribution of the COVID-19 vaccine. During the second quarter 2021, we have seenexperienced a sustained increase in leasing tour volume in our Manhattan office portfolio which led to about 84% of pre-Covid-19 pandemic levels. While the recent increase is a positive sign that some tenants are beginning to re-engage, any potential lease transactions that stem from these tours will likely appearour improved leasing performance in the second half of the year.third quarter 2021.
Our smaller food and service type retailers have been hit particularly hard. They provide critical amenities and services to our office tenants. In many instances, we have converted some of their fixed rent to a percentage rent structure, with a payback of the difference between current and percentage rent over a defined period.structure. We intend to support our food and service retailers so that they can service our office tenants whenas they continue to re-occupy.

Retailers, in general, have been hardest hit by the pandemic. Our retail-orientated tenants are no exception. As with all landlords, we are working with some of our retail tenants that are financially challenged. Some of these tenants may end up in bankruptcy or default in their leases in the near term.

On July 29, 2021, GBG USA Inc., an indirect wholly-owned subsidiary of Global Brands Group Holding Limited, announced that its North America wholesale business and certain subsidiaries and affiliates (collectively, “GBG USA”) filed for bankruptcy under Chapter 11.11 (the "GBG Bankruptcy"). At the time of the filing, GBG USA leased 353,325 square feet of office space at 1333 Broadway and the Empire State Building, or 3.5%, of our total portfolio rentable square feet, representing approximately 3.6% of total portfolio annualized rent.Of that total, all but 191,000 square feet, or 1.9% of our total portfolio rentable square feet, has been sublet to tenants, where both GBG USA and the subtenant are liable for the rent, and we have the right to require the subtenant to pay directly to us.

The sublets are for GBG USA’s entire premises at 1333 Broadway and have been in effect for several years.We have current discussions to convert the subtenants to direct tenants. Subsequently, GBG USA filed to reject their leases and both lease rejections were approved by the bankruptcy court during the third quarter.

In the third quarter we recorded a $1.6 million non-cash write-off of the straight-line receivables related to GBG USA's 1333 Broadway lease.

We collected rent from GBG USA through June 2021 and have converted the full balance of its $17.0 million letter of credit to cash, which we will applywas applied as follows:

place, and
We actively monitor these developments to review our alternatives. $10.1 million was recognized as lease termination income.

Observatory Operations
32









On March 16, 2020, we complied with governmental mandates regarding the closing of non-essential businesses in response to the COVID-19 pandemic and closed the Empire State Building Observatory. The 86th floor observatory deck reopened under New York State's Phase 4 guidelines, Low-Risk Outdoor Arts and Entertainment, on July 20, 2020. The2020 and the 102nd floor observation deck was reopened on August 24, 2020.
Due to the lifting of New York State COVID-19 restrictions, on June 16, 2021, the observatory fully reopened with interactive exhibits. We continue to operate with reduced hours, staffing, services, operating costs, credit card fees and marketing expenses. We have seen a higher local visitor mix, followed by a ramp up of nationally sourced travel. We

anticipate this pattern will then be followed by a restoration of our typical visitor mix that is approximately two-thirds international which we do not expect to be achieved until the broad resumption of international air travel some time in 2022. SecondFor the third quarter, 2021 attendancevisitor recapture versus 2019 was at nearly 17% of 2019 comparable attendance; a gradual improvement from 2020 levels and above our hypothetical admissions forecast.
We anticipate expenses to be approximately $6-7 million per quarterforecast in July and early August, but below our hypothetical admissions forecast for the balance of 2021 dependent upon the pace of visitor ramp-up.

third quarter. This was primarily due to the resurgent COVID-19 Delta variant and the impact on travel as U.S borders remain closed to international tourism. The government has announced that the borders will reopen to fully vaccinated international travelers in November 2021.
The closure and slow ramp-up of our observatory operations caused us during each quarter of 2020 and during the first and second quartersthroughout each quarter of 2021 to choose to perform an impairment test related to goodwill. We engaged a third-party valuation consulting firm to perform the valuation process. Based upon the results of the most recent goodwill impairment test of the stand-alone observatory reporting unit, which is after the intercompany rent expense paid to the Real Estate reporting unit, we determined that the fair value of the observatory reporting unit exceeded its carrying value by less than 15.0%. 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. We will continue to assess the impairment of the observatory reporting unit goodwill going forward and that continued assessment may again utilize a third-party valuation consulting firm. Goodwill allocated to the observatory reporting unit was $227.5 million at JuneSeptember 30, 2021.

Liquidity and Capital Resources

    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 fulfill other general business needs. Based on the
37









historical experience of our management and our business strategy, in the foreseeable future we anticipate we will generate
37


positive cash flows from operations. In order to qualify as a REIT, we are required under the Internal Revenue Code of 1986 to distribute to our stockholders, on an annual basis, at least 90% of our REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains. We expect to make quarterly distributions, as required, 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, debt issuances and unused borrowing capacity under our unsecured revolving 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, cash on hand, 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, cash on hand, 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. Our charter does not restrict the amount of leverage that we may use.

At JuneSeptember 30, 2021, we had $540.6$582.2 million available in cash and cash equivalents, and $850 million available under our unsecured revolving credit facility.

    For a five year right of first offer period expiring August 23, 2021, Q REIT Holding LLC, a Qatar Financial Centre limited liability company and a wholly owned subsidiary of the Qatar Investment Authority, a governmental authority of the State of Qatar (“QREIT”, together with any eligible transferee, “QIA”) will have a right of first offer to co-invest with us as a joint venture partner in real estate investment opportunities initiated by us where we have elected, at our discretion, to seek out a joint venture partner in real estate investment opportunities. The right of first offer period will be extended for 30 months beyond its original expiration date so long as at least one joint venture transaction is consummated by us and QIA during the initial five year term, and will be extended for a further 30-month term if at least one more joint venture transaction is consummated during such initial extension period.

As of JuneSeptember 30, 2021, we had approximately $2.1 billion of total consolidated indebtedness outstanding, with a weighted average interest rate of 3.9% and a weighted average maturity of 7.77.4 years. As of JuneSeptember 30, 2021, excluding principal amortization, we have no outstanding debt maturing until November 2024. Our consolidated net debt to total market capitalization was 31.4%34.7% as of JuneSeptember 30, 2021.
Unsecured Revolving Credit and Term Loan Facilities
    As described more fully in our Form 10-Q for the quarterly period ended March 31, 2021 (the "Q1 2021 10-Q"), in Q1 2021, we entered into an amended senior unsecured credit facility (the "Credit Facility") with Bank of America, N.A., as administrative agent and the other lenders party thereto. The Credit Facility is in the initial maximum principal amount of up to $1.065 billion, which consists of $850.0 million revolving credit facility that matures on March 31, 2025, and a $215.0 million term loan facility that matures on March 19, 2025. As of JuneSeptember 30, 2021, we had no borrowings under the revolving credit facility and $215.0 million under the term loan facility.
Additionally, as described more fully in the Q1 2021 10-Q, we have outstanding a senior unsecured term loan facility (the "Term Loan Facility") that we entered into on March 19, 2020 with Wells Fargo Bank, National Association, as administrative agent, and the other lenders party thereto. The Term loan Facility is in the original principal amount of $175.0 million and matures on December 31, 2026. As of JuneSeptember 30, 2021, our borrowings amounted to $175.0 million under the Term Loan Facility.
    The terms of both the Credit Facility and the Term Loan Facility include customary covenants, including limitations on liens, investment, distributions, debt, fundamental changes, and transactions with affiliates and require certain customary financial reports. Both facilities also require compliance with financial ratios including a maximum leverage ratio, a maximum secured leverage ratio, a minimum fixed charge coverage ratio, a minimum unencumbered interest coverage ratio, and a maximum unsecured leverage ratio. The agreements governing both facilities also contain customary events of default (subject in certain cases to specified cure periods), including but not limited to non-payment, breach of covenants,
38


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.As of JuneSeptember 30, 2021, we were in compliance with the covenants.
Senior Unsecured Notes
    The terms of the senior unsecured notes include customary covenants, including limitations on liens, investment, distributions, debt, fundamental changes, and transactions with affiliates and require certain customary financial reports. It also requires compliance with financial ratios including a maximum leverage ratio, a maximum secured leverage ratio, a minimum

fixed charge coverage ratio, a minimum unencumbered interest coverage ratio, and a maximum unsecured leverage ratio. The agreements also contain 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, the occurrence of certain change of control transactions and loss of real estate investment trust qualification. As of JuneSeptember 30, 2021, we were in compliance with the covenants under the outstanding senior unsecured notes.

Leverage Policies
We expect to employ leverage in our capital structure in amounts determined from time to time by our board of directors. Although our board of directors has not adopted a policy that limits the total amount of indebtedness that we may incur, we anticipate that our 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. Our 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. Our 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 our common stock, growth and acquisition opportunities and other factors.

Contractual Obligations
Refer to our Annual Report on Form 10-K for the year ended December 31, 2020 for a discussion of our contractual obligations. There have been no material changes, outside the ordinary course of business, to these contractual obligations during the sixnine months ended JuneSeptember 30, 2021.
Off-Balance Sheet Arrangements
As of JuneSeptember 30, 2021, we did not have any off-balance sheet arrangements.
Distribution Policy
In order to qualify as a REIT, we must distribute to our securityholders, on an annual basis, at least 90% of our REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains. In addition, we will be subject to U.S. federal income tax at regular corporate rates to the extent that we distribute less than 100% of our net taxable income (including net capital gains) and will be subject to a 4% nondeductible excise tax on the amount, if any, by which our distributions in any calendar year are less than a minimum amount specified under U.S. federal income tax laws.
40


We intend to distribute our net income to our securityholders in a manner intended to satisfy the REIT 90% distribution requirement and to avoid U.S. federal income tax liability on our income and the 4% nondeductible excise tax.
Before we pay any distribution, whether for U.S. federal income tax purposes or otherwise, 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
40









unfavorable or make a taxable distribution of our shares in order to satisfy the REIT 90% distribution requirement and to avoid U.S. federal income tax and the 4% nondeductible excise tax in that year.
In 2020, we had a unique situation whereby we had no requirement to pay a dividend beyond the quarterly dividends paid in the first and second quarters of 2020 due to two primary factors: (i) the significant decline in revenue due to lower levels of observatory visitation, and (ii) we had a net operating loss carryforward available to reduce the amount of REIT taxable income otherwise required to be distributed by us to meet REIT requirements. After careful consideration and focus on long-term shareholder value creation and preservation of our balance sheet strength and flexibility, our management and the Board of Directors concluded the best course of action was to temporarily suspend its quarterly dividend and to activate our share repurchase program. During August 2020, we announced the suspension of our third and fourth quarter 2020 dividends to holders of our Class A common stock and Class B common stock and to holders of Empire State Realty OP, L.P.’s Series ES, Series 250 and Series 60 operating partnership units and Series PR operating partnership units. During December 2020, we announced the continued dividend suspension for the first and second quarters of 2021. During May 2021, we announced our decision to reinstate the quarterly dividend, one quarter earlier than previously announced, driven by confidence in the New York City recovery and improvement in our results and liquidity. We declared a dividend of $0.035 per share for the secondthird quarter of 2021, which equates to an annualized rate of $0.14 per share. The Board of Directors will continue its regular review of its dividend and capital allocation policies at each Board meeting.
As of JuneSeptember 30, 2021, Empire State Realty Trust, Inc. had net operating loss ("NOL") carryforwards that may be used in the future to reduce the amount otherwise required to be distributed by us to meet REIT requirements. However, for federal income tax purposes, the NOL will not be able to offset more than 80% of our REIT taxable income and, therefore, may not be able to reduce the amount required to be distributed by us to meet REIT requirements to zero, except for the tax year ended December 31, 2020, of which we were able to offset 100% of our REIT taxable income in accordance with the Coronavirus Aid, Relief, and Economic Security (CARES) Act. The federal NOL may be carried forward indefinitely. Other limitations may apply to our ability to use our NOL to offset taxable income.
Distribution to Securityholders
Distributions and dividends amounting to $11.6$22.6 million and $64.3$65.4 million have been made to securityholders for the sixnine months ended JuneSeptember 30, 2021 and 2020, respectively.

Stock and Publicly Traded Operating Partnership Unit Repurchase Program

    Our Board of Directors authorized the repurchase of up to $500 million of our Class A common stock and the Operating Partnership’s Series ES, Series 250 and Series 60 operating partnership units through December 31, 2021. Under the program, we may purchase our Class A common stock and the Operating Partnership’s Series ES, Series 250 and Series 60 operating partnership units in accordance with applicable securities laws from time to time in the open market or in privately negotiated transactions. The timing, manner, price and amount of any repurchases will be determined by us at our discretion and will be subject to stock price, availability, trading volume and general market conditions. The authorization does not obligate us to acquire any particular amount of securities, and the program may be suspended or discontinued at our discretion without prior notice. There were noSee "Financial Statements - Note 9- Equity" for a summary of our purchases of equity securities duringin each of the three months ended JuneSeptember 30, 2021.

NOI is used by 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, (ii) 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, loss on early extinguishment of debt and loss from derivative financial instruments, 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 NOI because it is specific to the particular financing capabilities and constraints of the owner and 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, 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 titled measures and, accordingly, our NOI may not be comparable to similarly titled measures reported by other companies that do not define the measure exactly as we do.

The following table presents a reconciliation of our 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 write-off 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 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")
    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 two option properties following our formation transactions 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.

Core Funds From Operations ("Core FFO")
    Core FFO adds back to Modified FFO the following items: IPO litigation expense, severance expenses and loss on early extinguishment of debt. 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.

Factors That May Influence Future Results of Operations
Impact of COVID-19

    See "Overview" section.
Leasing
     We signed 0.9 million rentable square feet of new leases, expansions and lease renewals for the year ended December 31, 2020. During the sixnine months ended JuneSeptember 30, 2021, we signed 0.40.6 million rentable square feet of new leases, expansions and renewals.
    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 JuneSeptember 30, 2021, there were approximately 1.21.4 million rentable square feet of space in our portfolio available to lease (excluding leases signed but not yet commenced) representing 11.8%13.5% of the net rentable square footage of the properties in our portfolio. In addition, leases representing 4.9%2.3% and 5.6%5.5% of net rentable square footage of the properties in our portfolio will expire in 2021 and in 2022, respectively. These leases are expected to represent approximately 5.0%2.3% and 6.1%6.2%, 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.
    Despite the challenge of the uncertain near-term environment, we continue to believe that as we have largely completed 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, including 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 following the redevelopment and repositioning of our properties.
Observatory Operations
    On March 16, 2020, we complied with governmental mandates regarding the closing of non-essential businesses in response to the COVID-19 pandemic and closed the Empire State Building Observatory. The observatory was closed for the entirety of the second quarter 2020 and reopened the 86th floor observation deck on July 20, 2020 with new protocols and processes under New York State's Phase 4's Low-Risk Outdoor Arts and Entertainment guidelines. The 102nd floor observation deck reopened on August 24, 2020.
    The Observatory hosted approximately 255,000 visitors in the third quarter of 2021, compared to 162,000 visitors in the second quarter of 2021 compared to 51,000and 30,000 visitors in the firstthird quarter of 2021 and no visitors in the second quarter of 2020. In spite of the ongoing nature of international, national, and local travel restrictions and quarantines, the observatory has seen steady, weekly increases in visitors. Our return of attendance to pre-COVID-19 levels is closely tied to national and international travel trends and these remain adversely impacted by developments around the COVID-19 pandemic.    
    Observatory revenues for the three months ended June 30, 2021 were $8.4 million, driven by low visitation levels. Observatory expenses were $5.3 million for the three months ended June 30, 2021.
    Observatory revenues and admissions are dependent upon the following: (i) the number of tourists (domestic and international) who 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 other new and existing observatories; and (v) weather trends.

ITEM 3. 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 variable rate indebtedness. As of JuneSeptember 30, 2021, our floating rate debt of $125.0 million represented 2.2%2.5% of our total enterprise value.
Subject to maintaining our 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 on our unsecured revolving credit facility and debt refinancings. 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.

    As of JuneSeptember 30, 2021, we have an interest rate LIBOR swap agreement with an aggregate notional value of $265.0 million, which fixes the LIBOR interest rate at 2.1485% and matures on August 24, 2022. This interest rate swap has been designated as a cash flow hedge and is deemed highly effective with a fair value of $(6.2)$(4.9) million which is included in accounts payable and accrued expenses on the condensed consolidated balance sheet as of JuneSeptember 30, 2021.
Based on our variablefloating rate debt balances, interest expense would have increased by approximately $0.6$0.9 million for the sixnine months ended JuneSeptember 30, 2021, if short-term interest rates had been 1% higher. As of JuneSeptember 30, 2021, the weighted average interest rate on the $2.0 billion of fixed-rate indebtedness outstanding was 3.91% per annum, with maturities at various dates through March 17, 2035.
As of JuneSeptember 30, 2021, the fair value of our outstanding debt was approximately $2.2 billion, which was approximately $49.2$44.3 million moregreater 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.
On March 5, 2021, the Financial Conduct Authority (“FCA”) announced that USD LIBOR will no longer be published after June 30, 2023. This announcement has several implications, including setting the spread that may be used to automatically convert contracts from LIBOR to the Secured Overnight Financing Rate ("SOFR"). Additionally, banking regulators are encouraging banks to discontinue new LIBOR debt issuances by December 31, 2021.

    We anticipate that LIBOR will continue to be available at least until June 30, 2023. Any changes adopted by the FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in its current form.

We have contracts that are indexed to LIBOR and are monitoring and evaluating the related risks, which include interest on loans and amounts received and paid on derivative instruments. These risks arise in connection with transitioning contracts to an alternative rate, including any resulting value transfer that may occur, and are likely to vary by contract. The value of loans or derivative instruments tied to LIBOR, as well as interest rates on our unsecured revolving credit facility and our unsecured term loan facilities and the swap rate for our interest rate swap, may also be impacted if LIBOR is limited or discontinued. For some instruments the method of transitioning to an alternative reference rate may be challenging, especially if we cannot agree with the respective counterparty about how to make the transition.

While we expect LIBOR to be available in substantially its current form until at least the end of June 30, 2023, it is possible that LIBOR will become unavailable prior to that point. This could result, for example, if sufficient banks decline to make submissions to the LIBOR administrator. In that case, the risks associated with the transition to an alternative reference rate will be accelerated and magnified.

Alternative rates and other market changes related to the replacement of LIBOR, including the introduction of
47









financial products and changes in market practices, may lead to risk modeling and valuation challenges, such as adjusting interest rate accrual calculations and building a term structure for an alternative rate.

The introduction of an alternative rate also may create additional basis risk and increased volatility as alternative rates are phased in and utilized in parallel with LIBOR.

Adjustments to systems and mathematical models to properly process and account for alternative rates will be required, which may strain the model risk management and information technology functions and result in substantial incremental costs for us.

Our exposures to market risk have not changed materially since December 31, 2020.

ITEM 4. 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 our 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 JuneSeptember 30, 2021, the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of management, including our 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, our 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 our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
    No 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.
