Empire State Realty OP, L.P.
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," and the "company,” mean Empire State Realty OP, L.P. and its consolidated subsidiaries.
Empire State Realty OP, L.P. (the "Operating Partnership") is the entity through which Empire State Realty Trust, Inc. (“ESRT”), a self-administered and self-managed real estate investment trust ("REIT"), conducts all of its business and owns (either directly or through subsidiaries) substantially all of its assets. We own and manage a well-positioned property portfolio of office, retail and multifamily assets in Manhattan and the greater New York metropolitan area. As the owner of the Empire State Building, the World’s Most Famous Building, ESRT also owns and operates its iconic, newly reimagined Observatory Experience. As of June 30, 2022, our total portfolio contained 9.9 million rentable square feet of office, retail and multifamily space. We owned 13 office properties (including three long-term ground leasehold interests) encompassing approximately 9.2 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 retail space on their ground floor and/or contiguous levels. Our remaining four office properties are located in Fairfield County, Connecticut and Westchester County, New York, encompassing in the aggregate approximately 1.6 million rentable square feet. The majority of square footage for these four 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 June 30, 2022, our portfolio included 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. Additionally, at June 30, 2022, our portfolio included two multifamily properties totaling 625 units.
We were organized as a Delaware limited partnership on November 28, 2011 and operations commenced upon completion of the initial public offering of ESRT’s Class A common stock and related formation transactions on October 7, 2013. ESRT, as the sole general partner in our company, has responsibility and discretion in the management and control of our company, and our limited partners, in such capacity, have no authority to transact business for, or participate in the management activities, of our company. As of June 30, 2022, ESRT owned approximately 59.5% of our operating partnership units.
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, 2021 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, 2021 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. Historically, 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.

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. We had no VIEs as of June 30, 2022 and December 31, 2021.
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.
3. Property Disposition
During April 2022, we transferred 383 Main Avenue, Norwalk CT, which was encumbered by a $30.0 million mortgage, back to the lender in a consensual foreclosure and recognized a non-cash gain of $27.2 million, which is included in Gain on disposition of property in our condensed consolidated statements of operations. In December 2021, we recorded a $7.7 million impairment charge on the property as we had concluded the cost basis of the asset exceeded its fair value given our reduced holding period and new intent to transfer property ownership to the lender.
4. Deferred Costs, Acquired Lease Intangibles and Goodwill
Deferred costs, net, consisted of the following as of June 30, 2022 and December 31, 2021 (amounts in thousands):

Total deferred costs, net, excluding net deferred financing costs | $ | 187,372 |  |  | $ | 195,205 |

10

At June 30, 2022 and December 31, 2021, $6.1 million and $7.2 million, respectively, of net deferred financing costs associated with the unsecured revolving credit facility was included in deferred costs, net on the condensed consolidated balance sheets.
Amortization expense related to deferred leasing costs and acquired deferred leasing costs was $7.3 million and $6.1 million for the three months ended June 30, 2022 and 2021, respectively, and $14.3 million and $11.7 million for the six months ended June 30, 2022 and 2021, respectively. Amortization expense related to acquired lease intangibles was $4.1 million and $1.6 million for the three months ended June 30, 2022 and 2021, respectively, and $8.3 million and $3.3 million for the six months ended June 30, 2022 and 2021, respectively.
Amortizing acquired intangible assets and liabilities consisted of the following as of June 30, 2022 and December 31, 2021 (amounts in thousands):

| June 30, 2022 |  | December 31, 2021
Acquired below-market ground leases | $ | 396,916 |  |  | $ | 396,916 |
Less: accumulated amortization | (63,928) |  |  | (60,012) |
Acquired below-market ground leases, net | $ | 332,988 |  |  | $ | 336,904 |

| June 30, 2022 |  | December 31, 2021
Acquired below-market leases | $ | (64,635) |  |  | $ | (65,403) |
Less: accumulated amortization | 44,457 |  |  | 40,462 |
Acquired below-market leases, net | $ | (20,178) |  |  | $ | (24,941) |

Rental revenue related to the amortization of below-market leases, net of above-market leases, was $1.7 million and $0.7 million for the three months ended June 30, 2022 and 2021, respectively, and $3.5 million and $1.4 million for the six months ended June 30, 2022 and 2021, respectively.
As of June 30, 2022, 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 ended June 30, 2020, and each subsequent 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 methodology to review goodwill impairment, which included a significant amount of judgment and estimates, provided a reasonable basis to determine whether impairment had occurred. Based upon the results of the second quarter 2022 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.

Unsecured Revolving Credit and Term Loan Facilities
On March 31, 2021, we entered into a second amendment to an existing credit agreement ("Amended Credit Agreement") that governs 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 Amended Credit Agreement amended the amended and restated credit agreement dated August 29, 2017 by and among the parties named therein. 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 June 30, 2022, we had no borrowings under the revolving credit facility and $215.0 million under the term loan facility.
On March 19, 2020, we entered into a senior unsecured term loan facility (the “Term Loan Facility”) 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. We may request the Term Loan Facility be increased through one or more increases or the addition of new pari passu term loan tranches, for a maximum aggregate principal amount not to exceed $225 million. As of June 30, 2022, 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, representations or warranties, cross defaults, bankruptcy or other insolvency events, judgments, ERISA events, invalidity of loan documents, loss
13

of real estate investment trust qualification, and occurrence of a change of control. As of June 30, 2022, we were in compliance with these 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.

7. 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 its obligations.
In May 2022, we entered into forward interest rate swaps that aggregate $390.0 million to replace the $265.0 million swap which currently fixes the interest rate on a portion of our outstanding term loans balance and is due to expire in August 2022. The new swaps go into effect upon the expiration of the current swap and once effective, the interest rate on our term loans will be 100% fixed.
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 June 30, 2022, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $6.1 million. If we had breached any of these provisions at June 30, 2022, we could have been required to settle our obligations under the agreements at their termination value of $6.1 million.
As of June 30, 2022 and December 31, 2021, we had interest rate swaps and caps with an aggregate notional value of $841.3 million and $451.3 million, respectively. The notional value does not represent exposure to credit, interest rate or market risks. As of June 30, 2022, the fair value of our interest rate swaps amounted to $4.1 million, which is included in prepaid assets and other expenses and $(5.6) million which is included in accounts payable and accrued expenses on the condensed consolidated balance sheet. As of December 31, 2021, the fair value of our interest rate swaps amounted to $(25.3) million, which is included in accounts payable and accrued expenses on the condensed consolidated balance sheet. These interest rate swaps have been designated as cash flow hedges and hedge the variability in future cash flows associated with our existing
14

variable-rate term loan facilities. Interest rate caps not designated as hedges are not speculative and are used to manage our exposure to interest rate movements, but do not meet the strict hedge accounting requirements.
As of June 30, 2022 and 2021, our cash flow hedges are deemed highly effective and a net unrealized gain (loss) of $12.8 million and $2.8 million for the three months ended June 30, 2022 and 2021, respectively, and a net unrealized gain (loss) of $25.9 million and $5.7 million for the six months ended June 30, 2022 and 2021, 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 loss related to derivatives will be reclassified to interest expense as interest payments are made on the debt. We estimate that $2.4 million net loss of the current balance held in accumulated other comprehensive loss will be reclassified into interest expense within the next 12 months.
The table below summarizes the terms of agreements and the fair values of our derivative financial instruments as of June 30, 2022 and December 31, 2021 (amounts in thousands):

Fair Valuation
The estimated fair values at June 30, 2022 and December 31, 2021 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 values 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 by us.
The following tables summarize the carrying and estimated fair values of our financial instruments as of June 30, 2022 and December 31, 2021 (amounts in thousands):

Disclosure about the fair value of financial instruments is based on pertinent information available to us as of June 30, 2022 and December 31, 2021. 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.
8. 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 June 30, 2022 and 2021 condensed consolidated statements of operations as rental revenue.
16

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 six months ended June 30, 2022 and 2021 are as follows (amounts in thousands):

|  | Three Months Ended |  | Six Months Ended
Rental revenue |  | June 30, 2022 |  | June 30, 2021 |  | June 30, 2022 |  | June 30, 2021
Fixed payments |  | $ | 134,794 |  |  | $ | 124,432 |  |  | $ | 268,195 |  |  | $ | 250,204 |
Variable payments |  | 14,545 |  |  | 16,365 |  |  | 28,658 |  |  | 30,824 |

As of June 30, 2022, we were entitled to the following future contractual minimum lease payments (excluding operating expense reimbursements) on non-cancellable operating leases to be received which expire on various dates through 2039 (amounts in thousands):

Remainder of 2022 | $ | 244,025 |
2023 | 495,765 |
2024 | 473,800 |
2025 | 437,398 |
2026 | 396,072 |
Thereafter | 1,853,731 |
| $ | 3,900,791 |

The above future minimum lease payments exclude tenant recoveries and the net accretion of above and below-market lease intangibles. Some leases are subject to termination options generally upon payment of a termination fee. The preceding table is prepared assuming such options are not exercised.
Lessee
We determine if an arrangement is a lease at inception. Our operating lease agreements relate to three ground lease assets and are reflected in right-of-use assets of $28.8 million and lease liabilities of $28.8 million in our consolidated balance sheets as of June 30, 2022. 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.
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 Accounting Standards Update 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 June 30, 2022 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 June 30, 2022 was 47.9 years.
As of June 30, 2022, 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):

9. Commitments and Contingencies
Legal Proceedings
Except as described below, as of June 30, 2022, 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, 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 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 have appealed that ruling. On May 10, 2022, Respondents moved to dismiss the appeal and judgment on the grounds that a recent decision of the United States Supreme Court held that the federal courts have no subject matter jurisdiction over the case. Claimants opposed the motion, which is pending. 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 June 30, 2022, we estimate that we will incur approximately $105.3 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
18

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 June 30, 2022, 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 June 30, 2022, 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 June 30, 2022, 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 at our properties, that all necessary remediation actions have been or will be undertaken at our properties or that we will be indemnified, in full or at all, in the event that such environmental liabilities arise.
Insurance Coverage
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.
10. Capital
As of June 30, 2022, there were 162,689,535 share of Class A common stock 994,252 shares of Class B common stock and 111,420,579 operating partnership units outstanding, of which 163,683,787, or 59.5%, were owned by ESRT and 111,420,579, or 40.5%, were owned by other partners, including ESRT directors, members of senior management and other employees.
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 ESRT and the 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 ESRT common stock is 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 ESRT 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 ESRT 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 ESRT Class A common stock available for issuance under the 2019 Plan. In addition, shares of ESRT Class A common stock repurchased on the open market will not be added back to the shares of ESRT Class A common stock available for issuance under the 2019 Plan.
19

Long-term incentive plan ("LTIP") units are a special class of partnership interests. Each LTIP unit awarded will be deemed equivalent to an award of one share of ESRT stock under the Plans, reducing the availability for other equity awards on a one-for-one basis.
The vesting period for LTIP units, if any, will be determined at the time of issuance. Under the terms of the LTIP units, we will revalue for tax purposes its assets upon the occurrence of certain specified capital events, and any increase in valuation from the time of one such event to the next such event will be allocated first to the holders of LTIP units to equalize the capital accounts of such holders with the capital accounts of unitholders. Subject to any agreed upon exceptions, once vested and having achieved parity with unitholders, LTIP units are convertible into Series PR operating partnership units on a one-for-one basis.
LTIP units subject to time-based vesting, whether vested or not, receive per unit distributions as operating partnership units, which equal per share dividends (both regular and special) on our common stock. Market and performance-based LTIPs 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
ESRT's Board of Directors authorized the repurchase of up to $500 million of ESRT Class A common stock and the Operating Partnership’s Series ES, Series 250 and Series 60 operating partnership units from January 1, 2022 through December 31, 2023. Under the program, ESRT may purchase ESRT Class A common stock and we may purchase our 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 ESRT and us and will be subject to stock price, availability, trading volume, general market conditions, and applicable securities laws. The authorization does not obligate ESRT or us to acquire any particular amount of securities, and the program may be suspended or discontinued at ESRT and our discretion without prior notice.
The following table summarizes ESRT's purchases of equity securities in each of the three months ended June 30, 2022:

Period | Total Number of Shares Purchased |  | Weighted Average Price Paid per Share |  | Maximum Approximate Dollar Value Available for Future Purchase (in thousands)
April 2022 | 2,308,026 |  |  | $ | 8.95 |  |  | $ | 467,350 |
May 2022 | 1,050,731 |  |  | $ | 8.09 |  |  | $ | 458,849 |
June 2022 | 3,252,202 |  |  | $ | 7.16 |  |  | $ | 435,560 |

Private Perpetual Preferred Units
As of June 30, 2022, there were 4,664,038 Series 2019 Preferred Units ("Series 2019 Preferred Units") and 1,560,360 Series 2014 Private Perpetual Preferred Units ("Series 2014 Preferred Units") outstanding. The Series 2019 Preferred Units have a liquidation preference of $13.52 per unit and are entitled to receive cumulative preferential annual cash distributions of $0.70 per unit payable in arrears on a quarterly basis. The Series 2014 Preferred Units which have a liquidation preference of $16.62 per unit and are entitled to receive cumulative preferential annual cash distributions of $0.60 per unit payable in arrears on a quarterly basis. Both series are not redeemable at the option of the holders and are redeemable at our option only in the case of specific defined events.
Distributions
Total distributions paid to OP unitholders were $9.7 million and $19.5 million for the three and six months ended June 30, 2022, respectively, and $9.5 million for the three and six months ended June 30, 2021. Total distributions paid to preferred unitholders were $1.1 million and $2.1 million for the three and six months ended June 30, 2022, respectively, and $1.1 million and $2.1 million for the three and six months ended June 30, 2021, respectively.

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 ESRT common stock is authorized for issuance under awards granted pursuant to the 2019 Plan, and as of June 30, 2022, 5.9 million shares of ESRT common stock remain available for future issuance.
Annually, we make grants of LTIP units to our non-employee directors under the 2019 Plan. In 2022, each 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 in (i) cash at the face value of the award, (ii) immediately vesting equity at the face value of the award, or (iii) 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 142,358 LTIP units that are subject to time-based vesting with fair market values of $1.1 million. 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 51,284 LTIP units that are subject to immediate vesting with fair market values of $0.3 million.
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 for awards granted in 2020 and after and age of 60 for awards granted before 2020 and (ii) the date on which the employee has first completed ten years of continuous service with us or our affiliates. Share-based compensation for market-based equity awards and performance-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. Additionally, for the performance-based equity awards, we assess, at each reporting period, whether it is probable that the performance conditions will be satisfied. We recognize expense respective to the number of awards we expect to vest at the conclusion of the measurement period. Changes in estimate are accounted for in the period of change through a cumulative catch-up adjustment.
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 an appropriate 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 or performance 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, the fair value of the awards are based on the market price of ESRT stock at the grant date.
LTIP units and ESRT restricted stock issued during the six months ended June 30, 2022 were valued at $22.4 million. The weighted average per unit or share fair value was $7.21 for grants issued in 2022. The fair value per unit or share granted in 2022 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 2.0%, a risk-free interest rate from 1.4% to 2.0%, and an expected price volatility from 37.0% to 53.0%. No other stock options, dividend equivalents, or stock appreciation rights were issued or outstanding in 2022.
The following is a summary of ESRT restricted stock and LTIP unit activity for the six months ended June 30, 2022:

| Restricted Stock |  | Time-based LTIPs |  | Market-based LTIPs |  | Performance-based LTIPs |  | Weighted Average Grant Fair Value

21

The time-based LTIPs and ESRT restricted stock awards are treated for accounting purposes as immediately vested upon the later of (i) the date the grantee attains the age of 60 or 65, as applicable, and (ii) the date on which grantee has first completed ten years of continuous service with our company or its affiliates. For award agreements that qualify, we recognize noncash compensation expense on the grant date for the time-based awards and ratably over the vesting period for the market-based and performance-based awards, and accordingly, we recognized $0.6 million and $1.6 million for the three and six months ended June 30, 2022, respectively, and $0.4 million and $1.4 million for the three and six months ended June 30, 2021, respectively. Unrecognized compensation expense was $1.5 million at June 30, 2022, which will be recognized over a weighted average period of 3.6 years.
For the remainder of the LTIP unit and ESRT restricted stock awards, we recognize noncash compensation expense ratably over the vesting period, and accordingly, we recognized noncash compensation expense of $5.4 million and $8.9 million for the three and six months ended June 30, 2022, respectively, and $4.8 million and $8.6 million for the three and six months ended June 30, 2021, respectively. Unrecognized compensation expense was $35.1 million at June 30, 2022, which will be recognized over a weighted average period of 2.8 years.

11. Related Party Transactions
Supervisory Fee Revenue
We earned supervisory fees from entities affiliated with Anthony E. Malkin, our Chairman, President and Chief Executive Officer, of $0.3 million for the three months ended June 30, 2022 and 2021, and $0.5 million for the six months ended June 30, 2022 and 2021. These fees are included within third-party management and other fees.
22

Property Management Fee Revenue
We earned property management fees from entities affiliated with Anthony E. Malkin of $0.1 million and $0.1 million for the three months ended June 30, 2022 and 2021, respectively, and $0.1 million for the six months ended June 30, 2022 and 2021. These fees are included within third-party management and other fees.
Other
We receive rent generally at the market rental rate for 5,447 square feet of leased space from entities affiliated with Anthony E. Malkin at one of our properties. Under the lease, the tenant has the right to cancel such lease without special payment on 90 days’ notice. We also have a shared use agreement with such tenant, to occupy a portion of the leased premises as the office location for Peter L. Malkin, our chairman emeritus and employee, utilizing approximately 15% of the space, for which we pay to such tenant an allocable pro rata share of the cost. We also have agreements with these entities and excluded properties and businesses to provide them with general computer-related support services. Total revenue aggregated $0.1 million and $0.1 million for the three months ended June 30, 2022 and 2021, respectively, and $0.2 million for the six months ended June 30, 2022 and 2021.
12. Segment Reporting
We have identified two reportable segments: (1) real estate and (2) observatory. Our real estate segment includes all activities related to the ownership, management, operation, acquisition, 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 two lines of businesses are managed separately because each business requires different support infrastructures, provides different services and has dissimilar economic characteristics such as investments needed, stream of revenues and marketing strategies. We account for intersegment sales and rents as if the sales or rents were to third parties, that is, at current market prices.

Unless the context otherwise requires or indicates, references in this section to “we,” “our,” and “us” refer to our company and its consolidated subsidiaries. The following discussion related to our consolidated financial statements should be read in conjunction with the financial statements and the notes thereto appearing elsewhere in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2021.
FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We intend these forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and are including this statement for purposes of complying with those safe harbor provisions. You can identify forward-looking statements by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “approximately,” “intends,” “plans,” “estimates,” “contemplates,” “aims,” “continues,” “would” or “anticipates” or the negative of these words and phrases or similar words or phrases. In particular, statements pertaining to our capital resources, portfolio performance, dividend policy and results of operations contain forward-looking statements. Likewise, all of our statements regarding anticipated growth in our portfolio from operations, acquisitions and anticipated market conditions, demographics and results of operations are forward-looking statements.
Forward-looking statements are subject to substantial risks and uncertainties, many of which are difficult to predict and are generally beyond our control, and you should not rely on them as predictions of future events. Forward-looking statements depend on assumptions, data or methods which may be incorrect or imprecise, and we may not be able to realize them. We do not guarantee that the transactions and events described will happen as described (or that they will happen at all).
The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements: (i) economic, market, political and social impact of, and uncertainty relating to, the COVID-19 pandemic; (ii) a failure of conditions or performance regarding any event or transaction described herein, (iii) resolution of legal proceedings involving the Company; (iv) reduced demand for office, multifamily or retail space, including as a result of the COVID-19 pandemic and/or hybrid work schedules which allow work from remote locations other than the employer's office premises; (v) changes in our business strategy; (vi) changes in technology and market competition that affect utilization of our office, retail, broadcast or other facilities; (vii) changes in domestic or international tourism, including due to health crises such as the COVID-19 pandemic, geopolitical events, including global hostilities, currency exchange rates, and/or competition from recently opened observatories in New York City, any or all of which may cause a decline in observatory visitors; (viii) defaults on, early terminations of, or non-renewal of, leases by tenants; (ix) increases or uncertainty in interest rates, including the phasing out of LIBOR, which may negatively affect the Company’s borrowing costs and the market valuation of real property assets generally; (x) declining real estate valuations and impairment charges; (xi) termination of our ground leases; (xii) changes in our ability to pay down, refinance, restructure or extend our indebtedness as it becomes due and potential limitations on our ability to borrow additional funds in compliance with drawdown conditions and financial covenants; (xiii) decreased rental rates or increased vacancy rates; (xiv) our failure to execute any newly planned capital project successfully or on the anticipated timeline or at the anticipated costs; (xv) difficulties in identifying and completing acquisitions; (xvi) risks related to our development projects (including our Metro Tower development site); (xvii) impact of changes in governmental regulations, tax laws and rates and similar matters; (xviii) our failure to qualify as a REIT; (xix) environmental uncertainties and risks related to climate change, adverse weather conditions, rising sea levels and natural disasters; and (xx) accuracy of our methodologies and estimates regarding ESG metrics and goals, tenant willingness and ability to collaborate in reporting ESG metrics and meeting ESG goals, and the impact of governmental regulation on our ESG efforts; (xxi) economic cycles involving inflation and/or recession; (xxii) supply chain disruptions which may limit or delay our timely sourcing of supplies for the maintenance of our facilities and equipment. For a further discussion of these and other factors that could impact the Company's future results, performance or transactions, see the section entitled “Risk Factors” in this Quarterly Report on Form 10-Q, and in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, and other risks described in documents subsequently filed by the Company from time to time with the Securities and Exchange Commission.
While forward-looking statements reflect the Company's good faith beliefs, they are not guarantees of future performance. The Company disclaims any obligation to update or revise publicly any forward-looking statement to reflect changes in underlying assumptions or factors, new information, data or methods, future events, or other changes after the date of this Quarterly
Report on Form 10-Q, except as required by applicable law. Prospective investors should not place undue reliance on any forward-looking statements, which are based only on information currently available to the Company.

Rental Revenue
The increase in rental revenue reflects the inclusion of revenue from our recently acquired multifamily properties.
Observatory Revenue
Observatory revenues were higher driven by increased visitation
Other Revenues and Fees
The increase in other revenues and fees was due to higher food and beverage sales, insurance claim income, parking income and bad debt recovery income.
Property Operating Expenses
The increase in property operating expenses reflects higher payroll, utilities, cleaning and other operating expenses, and the inclusion of operating expenses from our recently acquired multifamily properties.
General and Administrative Expenses
The increase in general and administrative expenses reflects higher equity compensation and payroll costs, information technology costs and professional fees.
30

Observatory Expenses
The increase in observatory expenses was driven by increased operating hours, which increased variable costs such as labor, union, security, cleaning and maintenance costs.
Real Estate Taxes
Lower real estate taxes were attributable to the overall reduction in property tax assessment values.
Depreciation and Amortization
The increase in depreciation and amortization reflects accelerated depreciation at one property due to an impairment charge taken in the fourth quarter of 2021 and additional depreciation from our recently acquired multifamily properties.
Interest Expense
The increase reflects additional interest expense from our recently acquired multifamily properties, partially offset by the cancellation of debt from 383 Main Avenue, Norwalk CT.
Income Taxes
The decrease in income tax benefit was attributable to higher net operating income for the observatory segment.
Gain on disposition of property
Represents a gain on the transfer of 383 Main Avenue, Norwalk CT, which was encumbered by a $30.0 million mortgage, back to the lender in a consensual foreclosure.

The increase in property operating expenses reflects higher payroll, utilities, repairs and maintenance costs, cleaning and other operating expenses, and the inclusion of operating expenses from our recently acquired multifamily properties.
General and Administrative Expenses
The increase in general and administrative expenses reflects higher equity compensation and payroll costs, information technology costs and professional fees.
Observatory Expenses
The increase in observatory expenses was driven by increased operating hours, which increased variable costs such as labor, union, security, cleaning and maintenance costs.
Real Estate Taxes
Lower real estate taxes were attributable to the overall reduction in property tax assessment values.
Depreciation and Amortization
The increase in depreciation and amortization reflects accelerated depreciation at one property due to an impairment charge in the fourth quarter of 2021 and additional depreciation from our recently acquired multifamily properties.
Interest Expense
The increase in interest expense reflects additional interest expense from our recently acquired multifamily properties, partially offset by the cancellation of debt from 383 Main Avenue, Norwalk CT.
Income Taxes
The decrease in income tax benefit was attributable to higher net operating income for the observatory segment.
Gain on disposition of property
Represents a gain on the transfer of 383 Main Avenue, Norwalk CT, which was encumbered by a $30.0 million mortgage, back to the lender in a consensual foreclosure.
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 historical experience of our management and our business strategy, in the foreseeable future we anticipate we will generate positive cash flows from operations. In order for ESRT to qualify as a REIT, ESRT is required under the Internal Revenue Code of 1986 to distribute to its stockholders, on an annual basis, at least 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding net capital gains. We expect to make quarterly distributions, 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
33

investments of capital for individual lease related tenant improvements allowances, general capital improvements and costs associated with capital expenditures. Our overall leverage will depend on our mix of investments and the cost of leverage. ESRT's charter does not restrict the amount of leverage that we may use.
At June 30, 2022, we had $359.4 million available in cash and cash equivalents, and $850 million available under our unsecured revolving credit facility.
As of June 30, 2022, we had approximately $2.3 billion of total consolidated indebtedness outstanding, with a weighted average interest rate of 3.9% and a weighted average maturity of 6.9 years. As of June 30, 2022, excluding principal amortization, we have no outstanding debt maturing until November 2024. Our consolidated net debt to total market capitalization was 49.0% as of June 30, 2022.
Unsecured Revolving Credit and Term Loan Facilities
See "Financial Statements - Note 5. Debt" for a summary of our unsecured revolving credit and term loan facilities.
Mortgage Debt
As of June 30, 2022, mortgage notes payable amounted to $935.1 million. The first maturity is in 2024. See "Financial Statements - Note 5. Debt" for more information on mortgage debt.
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 June 30, 2022, we were in compliance with the covenants under the outstanding senior unsecured notes.
Financial Covenants
As of June 30, 2022, we were in compliance with the following financial covenants:

Financial covenant | Required | June 30, 2022 | In Compliance
Maximum total leverage | < 60% | 31.6 | % | Yes
Maximum secured leverage | < 40% | 12.7 | % | Yes
Minimum fixed charge coverage | > 1.50x | 3.4x | Yes
Minimum unencumbered interest coverage | > 1.75x | 6.6x | Yes
Maximum unsecured leverage | < 60% | 23.2 | % | Yes

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

Capital expenditures are considered part of both our short-term and long-term liquidity requirements. We intend to fund capital improvements through a combination of operating cash flow, cash on hand and borrowings under the unsecured revolving credit facility.
Off-Balance Sheet Arrangements
As of June 30, 2022, we did not have any off-balance sheet arrangements.
Distribution Policy
We intend to distribute our net taxable income to our security holders in a manner intended to satisfy REIT distribution requirements and to avoid U.S. federal income tax liability on our income.
35

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 unfavorable or make a taxable distribution of our shares in order to satisfy REIT distribution requirements.
Distribution to Equity Holders
Distributions and dividends amounting to $21.6 million and $11.6 million have been made to equity holders for the six months ended June 30, 2022 and 2021, respectively.
Stock and Publicly Traded Operating Partnership Unit Repurchase Program
ESRT's Board of Directors authorized the repurchase of up to $500 million of ESRT Class A common stock and the Operating Partnership’s Series ES, Series 250 and Series 60 operating partnership units through December 31, 2023. Under the program, ESRT may purchase ESRT Class A common stock and we may purchase our 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 ESRT and us at our discretion and will be subject to stock price, availability, trading volume and general market conditions. The authorization does not obligate ESRT or us to acquire any particular amount of securities, and the program may be suspended or discontinued at ESRT and our discretion without prior notice. re any particular amount of securities, and the program may be suspended or discontinued at our discretion without prior notice. See "Financial Statements - Note 10. Capital" for a summary of ESRT's purchases of equity securities in each of the three months ended June 30, 2022.
Cash Flows
Comparison of Six Months Ended June 30, 2022 to the Six Months Ended June 30, 2021
Net cash. Cash and cash equivalents and restricted cash were $412.8 million and $578.6 million, respectively, as of June 30, 2022 and 2021. The decrease was primarily due to the acquisition of real estate property at the end of 2021 and higher spending for capital expenditures, higher repurchases of common shares and higher dividends paid in 2022.
Operating activities. Net cash provided by operating activities was $83.7 million, equal to prior year.
Investing activities. Net cash used in investing activities increased by $8.2 million to $56.6 million due to higher capital expenditures.
Financing activities. Net cash used in financing activities increased by $64.2 million to $88.9 million primarily due to higher repurchases of common shares and higher dividends and distributions.
Net Operating Income ("NOI")
Our financial reports include a discussion of property net operating income, or NOI. NOI is a non-GAAP financial measure of performance. NOI is used by 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 to investors because the resulting
36

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, we believe
37

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 believe 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 believe it is 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 adds back to Modified FFO the following items: IPO litigation expense, severance expenses and loss on early extinguishment of debt. The company believes Core FFO is an important supplemental measure of its operating performance because it excludes items associated with its IPO and formation transactions and other non-recurring items. There can be no assurance that Core FFO presented by the company is comparable to similarly titled measures of other REITs. Core FFO does not represent cash generated from operating activities and should not be considered as an alternative to net income (loss) determined in accordance with GAAP or to cash flow from operating activities determined in accordance with GAAP. Core FFO is not indicative of cash available to fund ongoing cash needs, including the ability to make cash distributions. In future periods, we may also exclude other items from Core FFO that we believe may help investors compare our results.
The following table presents a reconciliation of our net income, the most directly comparable GAAP measure, to FFO, Modified FFO and Core FFO for the periods presented (amounts in thousands):

Factors That May Influence Future Results of Operations
Leasing
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 June 30, 2022, there were approximately 1.2 million rentable square feet of space in our portfolio available to lease (excluding leases signed but not yet commenced) representing 12.2% of the net rentable square footage of the properties in our portfolio. In addition, leases representing 3.4% and 6.2% of net rentable square footage of the properties in our portfolio will expire in 2022 and in 2023, respectively. These leases are expected to represent approximately 4.0% and 7.2%, 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 rental revenues. 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 obtain better quality tenants, whom have higher likelihood for growth within the portfolio, following the redevelopment and repositioning of our properties.
Observatory Operations
For the three months ended June 30, 2022, the observatory hosted 573,000 visitors, compared to 162,000 visitors for the same period in 2021. 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.
39

Observatory revenue for the three months ended June 30, 2022 was $27.4 million, compared to $8.4 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.
Critical Accounting Estimates
Refer to our Annual Report on Form 10-K for the year ended December 31, 2021 for a discussion of our critical accounting estimates. There were no material changes to our critical accounting estimates disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021.

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. We are exposed to interest rate changes primarily on our unsecured revolving credit facility and debt refinancings. In order to mitigate our interest rate risk, we may borrow at fixed rates or may enter into derivative financial instruments such as interest rate swaps or caps on floating rate financial instruments. We are not subject to foreign currency risk and we do not enter into derivative or interest rate transactions for speculative purposes.
As of June 30, 2022, our floating rate debt of $125.0 million represented 5.4% of our total debt. We have interest rate LIBOR swap and cap agreements with an aggregate notional value of $841.3 million and which mature between August 24, 2022 and November 1, 2033. These "variable to fixed" interest rate swaps have been designated as cash flow hedges and are deemed highly effective with fair values of $4.1 million and $(5.6) million which is included in prepaid assets and other expenses and in accounts payable and accrued expenses, respectively, on the condensed consolidated balance sheet as of June 30, 2022. Given the phasing out of LIBOR, we have entered into SOFR swap agreements to begin the replacement of our LIBOR swap agreements. We will continue to work with our lenders and counterparties to replace or modify, as appropriate, the interest rate provisions in our other LIBOR swap and cap agreements.
Based on our floating rate debt balances, interest expense would have increased by approximately $0.6 million for the three months ended June 30, 2022, if short-term interest rates had been 1% higher. As of June 30, 2022, the weighted average interest rate on the $2.2 billion of fixed-rate indebtedness outstanding was 3.9% per annum, with maturities at various dates through March 17, 2035.
As of June 30, 2022, the fair value of our outstanding debt was approximately $2.1 billion, which was approximately $137.4 million less than the book value as of such date. Interest risk amounts were determined by considering the impact of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of any change in overall economic activity that could occur in that environment. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure.
ITEM 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 ESRT's Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
As of June 30, 2022, the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of ESRT management, including ESRT's Chief Executive Officer and Chief Financial Officer, regarding the effectiveness of our disclosure controls and procedures at the end of the period covered by this report. Based on the foregoing, ESRT's Chief Executive Officer and Chief Financial Officer concluded, as of that time, that our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in reports filed or submitted under the Exchange Act (i) is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) is accumulated and communicated to our management, including ESRT's Chief Executive Officer and Chief Financial Officer, as appropriate to allow for timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
No 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.

Stock and Publicly Traded Operating Partnership Unit Repurchase Program
ESRT's 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 during the period from January 1, 2022 through December 31, 2023. This replaces an earlier $500.0 million repurchase authorization that ran from January 1, 2021 through December 31, 2021. Under the program, ESRT may purchase our Class A common stock and we may purchase our 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 ESRT and us and will be subject to stock price, availability, trading volume, general market conditions, and applicable securities laws. The authorization does not obligate ESRT or us to acquire any particular amount of securities, and the program may be suspended or discontinued at ESRT and our discretion without prior notice.
The following table summarizes ESRT's repurchases of equity securities in each of the months in the three month period ended June 30, 2022 under the repurchase program described above:
