NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1.Organization

Alexander’s, Inc. (NYSE: ALX) is a real estate investment trust (“REIT”), incorporated in Delaware, engaged in leasing, managing, developing and redeveloping its properties. All references to “we,” “us,” “our,” “Company” and “Alexander’s” refer to Alexander’s, Inc. and its consolidated subsidiaries. We are managed by, and our properties are leased and developed by, Vornado Realty Trust (“Vornado”) (NYSE: VNO). We have five properties in New York City.

2.Basis of Presentation

The accompanying consolidated financial statements are unaudited and include the accounts of Alexander’s and its consolidated subsidiaries. All adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and changes in cash flows have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted. These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q of the Securities and Exchange Commission (the “SEC”) and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC.

We have made estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the operating results for the full year.

We operate in one reportable segment.

3.Recently Issued Accounting Literature

In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04 establishing Accounting Standards Codification (“ASC”) Topic 848, Reference Rate Reform, and in January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope (collectively, “ASC 848”). ASC 848 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASC 848 is optional and may be elected over time as reference rate reform activities occur. We have elected to apply the hedge accounting expedients related to probability and the 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. In December 2022, the FASB issued ASU 2022-06, Deferral of the Sunset Date of Topic 848 (“ASU 2022-06”) which was issued to defer the sunset date of ASC 848 to December 31, 2024. ASU 2022-06 is effective immediately for all companies. As of September 30, 2023, we have transitioned all of our LIBOR-indexed debt and derivatives and, for our derivatives in hedge accounting relationships, utilized the elective relief in ASC 848, allowing for the continuation of hedge accounting through the transition process.

The following is a summary of revenue sources for the three and nine months ended September 30, 2023 and 2022.

The components of lease revenues for the three and nine months ended September 30, 2023 and 2022 are as follows:


	For the Three Months Ended September 30,				For the Nine Months Ended September 30,
(Amounts in thousands)	2023		2022		2023		2022

Bloomberg L.P. (“Bloomberg”) accounted for revenue of $89,863,000 and $81,536,000 for the nine months ended September 30, 2023 and 2022, respectively, representing approximately 55% and 53% of our rental revenues in each period, respectively. No other tenant accounted for more than 10% of our rental revenues. If we were to lose Bloomberg as a tenant, or if Bloomberg were to be unable to fulfill its obligations under its lease, it would adversely affect our results of operations and financial condition. In order to assist us in our continuing assessment of Bloomberg’s creditworthiness, we receive certain confidential financial information and metrics from Bloomberg. In addition, we access and evaluate financial information regarding Bloomberg from other private sources, as well as publicly available data.

On December 3, 2022, IKEA closed its 112,000 square foot store at our Rego Park I property under a lease that was set to expire in December 2030. The lease included a right to terminate effective no earlier than March 16, 2026, subject to payment of rent through the termination date and an additional termination payment equal to the lesser of $10,000,000 or the amount of rent due under the remaining term. On September 27, 2023, we entered into a lease modification agreement with IKEA which accelerates its lease termination date to April 1, 2024. Under the lease modification agreement, IKEA will pay its remaining rent due through March 16, 2026 and the $10,000,000 termination payment over the modified lease term.

5.Real Estate Sale

On May 19, 2023, we sold the Rego Park III land parcel in Queens, New York, for $71,060,000 inclusive of consideration for Brownfield tax benefits and reimbursement of costs for plans, specifications and improvements to date. Net proceeds from the sale were $67,821,000 after closing costs and the financial statement gain was $53,952,000.

In the event third-party real estate brokers are used, the fees to Vornado increase by 1% and Vornado is responsible for the fees to the third-party real estate brokers.

Vornado is also entitled to a commission upon the sale of any of our assets equal to 3% of gross proceeds, as defined, for asset sales less than $50,000,000 and 1% of gross proceeds, as defined, for asset sales of $50,000,000 or more (the “Sales Agreement”). Pursuant to the Sales Agreement, we paid a $711,000 sales commission to Vornado in the second quarter of 2023 related to the sale of the Rego Park III land parcel.

We also have agreements with Building Maintenance Services, a wholly owned subsidiary of Vornado, to supervise (i) cleaning, engineering and security services at our Lexington Avenue property and (ii) security services at our Rego Park I and Rego Park II properties and The Alexander apartment tower.

7.Mortgages Payable

On June 9, 2023, we exercised our remaining one-year extension option on the $500,000,000 interest-only mortgage loan on the office condominium of our 731 Lexington Avenue property. The interest rate on the loan remained at LIBOR plus 0.90% through July 15, 2023 and thereafter at the Prime Rate through loan maturity on June 11, 2024. In June 2023, we purchased an interest rate cap for $11,258,000, which capped LIBOR at 6.00% through July 15, 2023 and caps the Prime Rate (8.50% as of September 30, 2023) at 6.00% through loan maturity.

The following is a summary of our outstanding mortgages payable as of September 30, 2023 and December 31, 2022. We may refinance our maturing debt as it comes due or choose to pay it down.

(4)Interest at SOFR plus 1.45% (SOFR is capped at 4.15% through November 2024).

8.Stock-Based Compensation

We account for stock-based compensation in accordance with ASC Topic 718, Compensation – Stock Compensation (“ASC 718”). Our 2016 Omnibus Stock Plan (the “Plan”) provides for grants of incentive and non-qualified stock options, restricted stock, stock appreciation rights, deferred stock units (“DSUs”) and performance shares, as defined, to the directors, officers and employees of the Company and Vornado.

In May 2023, we granted each of the members of our Board of Directors 449 DSUs with a market value of $75,000 per grant. The grant date fair value of these awards was $56,250 per grant, or $450,000 in the aggregate, in accordance with ASC 718. The DSUs entitle the holders to receive shares of the Company’s common stock without the payment of any consideration. The DSUs vested immediately and accordingly, were expensed on the date of grant, but the shares of common stock underlying the DSUs are not deliverable to the grantee until the grantee is no longer serving on the Company’s Board of Directors. As of September 30, 2023, there were 23,388 DSUs outstanding and 482,399 shares were available for future grant under the Plan.

9.Fair Value Measurements

ASC Topic 820, Fair Value Measurement (“ASC 820”) defines fair value and establishes a framework for measuring fair value. ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities as well as certain U.S. Treasury securities that are highly liquid and are actively traded in secondary markets; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as consider counterparty credit risk in our assessment of fair value.

Financial Assets and Liabilities Measured at Fair Value

Financial assets measured at fair value on our consolidated balance sheet as of September 30, 2023 consisted of interest rate derivatives, which are presented in the table below based on their level in the fair value hierarchy. There were no financial liabilities measured at fair value as of September 30, 2023.

Interest Rate Derivatives

We recognize the fair value of all interest rate derivatives in “other assets” or “other liabilities” on our consolidated balance sheets and since all of our interest rate derivatives have been designated as cash flow hedges, changes in the fair value are recognized in other comprehensive income. The table below summarizes our interest rate derivatives, all of which hedge the interest rate risk attributable to the variable rate debt noted as of September 30, 2023 and December 31, 2022, respectively.

(2)In June 2023, we purchased an interest rate cap for $11,258, which capped LIBOR at 6.00% through July 15, 2023 and caps the Prime Rate (8.50% as of September 30, 2023) at 6.00% through loan maturity. See Note 7 - Mortgages Payable for further information.

Financial Assets and Liabilities not Measured at Fair Value

Financial assets and liabilities that are not measured at fair value on our consolidated balance sheets include cash equivalents and mortgages payable. Cash equivalents are carried at cost, which approximates fair value due to their short-term maturities and are classified as Level 1. The fair value of our mortgages payable is calculated by discounting the future contractual cash flows of these instruments using current risk-adjusted rates available to borrowers with similar credit ratings, which are provided by a third-party specialist, and is classified as Level 2. The table below summarizes the carrying amount and fair value of these financial instruments as of September 30, 2023 and December 31, 2022.

10.Commitments and Contingencies

Insurance

We maintain general liability insurance with limits of $300,000,000 per occurrence and per property, of which the first $30,000,000 includes communicable disease coverage, and all-risk property and rental value insurance coverage with limits of $1.7 billion per occurrence, including coverage for acts of terrorism, with sub-limits for certain perils such as floods and earthquakes on each of our properties and excluding communicable disease coverage.

Fifty Ninth Street Insurance Company, LLC (“FNSIC”), our wholly owned consolidated subsidiary, acts as a direct insurer for coverage for acts of terrorism, including nuclear, biological, chemical and radiological (“NBCR”) acts, as defined by the Terrorism Risk Insurance Act of 2002, as amended to date and which has been extended through December 2027. Coverage for acts of terrorism (including NBCR acts) is up to $1.7 billion per occurrence and in the aggregate. Coverage for acts of terrorism (excluding NBCR acts) is fully reinsured by third party insurance companies and the Federal government with no exposure to FNSIC. For NBCR acts, FNSIC is responsible for a $316,000 deductible and 20% of the balance of a covered loss, and the Federal government is responsible for the remaining 80% of a covered loss. We are ultimately responsible for any loss incurred by FNSIC.

We continue to monitor the state of the insurance market and the scope and costs of coverage for acts of terrorism or other events. However, we cannot anticipate what coverage will be available on commercially reasonable terms in the future. We are responsible for uninsured losses and for deductibles and losses in excess of our insurance coverage, which could be material.

The principal amounts of our mortgage loans are non-recourse to us and the loans contain customary covenants requiring us to maintain insurance. Although we believe that we have adequate insurance coverage for purposes of these agreements, we may not be able to obtain an equivalent amount of coverage at reasonable costs in the future. If lenders insist on greater coverage than we are able to obtain, it could adversely affect our ability to finance or refinance our properties.

Letters of Credit

Approximately $900,000 of standby letters of credit were issued and outstanding as of September 30, 2023.

Other

There are various legal actions brought against us from time-to-time in the ordinary course of business. In our opinion, the outcome of such pending matters in the aggregate will not have a material effect on our financial position, results of operations or cash flows.

11.Earnings Per Share

The following table sets forth the computation of basic and diluted income per share, including a reconciliation of net income and the number of shares used in computing basic and diluted income per share. Basic income per share is determined using the weighted average shares of common stock (including deferred stock units) outstanding during the period. Diluted income per share is determined using the weighted average shares of common stock (including deferred stock units) outstanding during the period, and assumes all potentially dilutive securities were converted into common shares at the earliest date possible. There were no potentially dilutive securities outstanding during the three and nine months ended September 30, 2023 and 2022.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Alexander’s, Inc.

Results of Review of Interim Financial Information

We have reviewed the accompanying consolidated balance sheet of Alexander’s, Inc. and subsidiaries (the “Company”) as of September 30, 2023, the related consolidated statements of income, comprehensive income, and changes in equity, for the three-month and nine-month periods ended September 30, 2023, and 2022, and of cash flows for the nine-month periods ended September 30, 2023 and 2022, and the related notes (collectively referred to as the “interim financial information”). Based on our reviews, we are not aware of any material modifications that should be made to the accompanying interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2022, and the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for the year then ended (not presented herein); and in our report dated February 13, 2023, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2022, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Basis for Review Results

This interim financial information is the responsibility of the Company's management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our reviews in accordance with standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Item 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Certain statements contained in this Quarterly Report constitute forward-looking statements as such term is defined in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are not guarantees of future performance. They represent our intentions, plans, expectations and beliefs and are subject to numerous assumptions, risks and uncertainties. Our future results, financial condition, results of operations and business may differ materially from those expressed in these forward-looking statements. You can find many of these statements by looking for words such as “approximates,” “believes,” “expects,” “anticipates,” “estimates,” “intends,” “plans,” “would,” “may” or other similar expressions in this Quarterly Report on Form 10-Q. Many of the factors that will determine these items are beyond our ability to control or predict. For a further discussion of factors that could materially affect the outcome of our forward-looking statements, see “Item 1A - Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022.

Currently, some of these factors are the impacts of the increase in interest rates and inflation on our business, financial condition, results of operations, cash flows, operating performance and the effect that these factors have had and may continue to have on our tenants, the global, national, regional and local economies and financial markets and the real estate market in general.

For these statements, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. You are cautioned not to place undue reliance on the forward-looking statements, which speak only as of the date of this Quarterly Report on Form 10-Q or the date of any document incorporated by reference. All subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. We do not undertake any obligation to release publicly, any revisions to our forward-looking statements to reflect events or circumstances after the date of this Quarterly Report on Form 10-Q.

Management’s Discussion and Analysis of Financial Condition and Results of Operations include a discussion of our consolidated financial statements for the three and nine months ended September 30, 2023 and 2022. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. The results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the operating results for the full year.

Critical Accounting Estimates and Significant Accounting Policies

A summary of the critical accounting estimates used in the preparation of our consolidated financial statements is included in our Annual Report on Form 10-K for the year ended December 31, 2022 in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and a summary of our significant accounting policies is included in “Note 2 – Summary of Significant Accounting Policies” to the consolidated financial statements included therein. For the nine months ended September 30, 2023, there were no material changes to these policies.

Overview

We compete with a large number of property owners and developers. Our success depends upon, among other factors, trends of the global, national and local economies, the financial condition and operating results of current and prospective tenants and customers, the availability and cost of capital, construction and renovation costs, taxes, governmental regulations, legislation, population and employment trends, zoning laws, and our ability to lease, sublease or sell our properties, at profitable levels. Our success is also subject to our ability to refinance existing debt on acceptable terms as it comes due.

Our business has been, and may continue to be, affected by the increase in inflation and interest rates, and other uncertainties including the potential for an economic downturn. These factors could have a material impact on our business, financial condition, results of operations and cash flows.

Net Gain on Sale of Real Estate

Net gain on sale of real estate was $53,952,000 for the nine months ended September 30, 2023, resulting from the sale of the Rego Park III land parcel in Queens, New York.

Liquidity and Capital Resources

Cash Flows

Rental revenue is our primary source of cash flow and is dependent on a number of factors, including the occupancy level and rental rates of our properties, as well as our tenants’ ability to pay their rents. Our properties provide us with a relatively consistent stream of cash flow that enables us to pay our operating expenses, interest expense, recurring capital expenditures and cash dividends to stockholders. Other sources of liquidity to fund cash requirements include our existing cash, proceeds from financings, including mortgage or construction loans secured by our properties and proceeds from asset sales.

As of September 30, 2023, we had $529,081,000 of liquidity comprised of cash and cash equivalents and restricted cash. The ongoing challenges posed by the increase in interest rates and inflation could adversely affect our cash flow from continuing operations but we anticipate that cash flow from continuing operations over the next twelve months, together with existing cash balances, will be adequate to fund our business operations, cash dividends to stockholders, debt service and capital expenditures. We may refinance our maturing debt as it comes due or choose to pay it down. However, there can be no assurance that additional financing or capital will be available to refinance our debt, or that the terms will be acceptable or advantageous to us.

For the Nine Months Ended September 30, 2023

Cash and cash equivalents and restricted cash were $529,081,000 as of September 30, 2023, compared to $214,478,000 as of December 31, 2022, an increase of $314,603,000. This increase resulted from (i) $319,537,000 of net cash provided by investing activities and (ii) $64,367,000 of net cash provided by operating activities, partially offset by (iii) $69,301,000 of net cash used in financing activities.

Net cash provided by investing activities of $319,537,000 was comprised of (i) $264,881,000 of proceeds from maturities of U.S. Treasury bills, (ii) $67,821,000 of proceeds from sale of real estate and (iii) $1,889,000 of proceeds from interest rate cap, partially offset by (iv) the purchase of interest rate cap of $11,258,000 and (v) construction in progress and real estate additions of $3,796,000.

Net cash provided by operating activities of $64,367,000 was comprised of (i) net income of $86,127,000, partially offset by (ii) the net change in operating assets and liabilities of $4,322,000 and (iii) adjustments for non-cash items of $17,438,000. The adjustments for non-cash items were comprised of (i) net gain on sale of real estate of $53,952,000, partially offset by (ii) depreciation and amortization (including amortization of debt issuance costs) of $24,771,000, (iii) straight-lining of rents of $5,949,000, (iv) interest rate cap premium amortization of $4,049,000, (v) other non-cash adjustments of $1,295,000 and (vi) stock-based compensation expense of $450,000.

Net cash used in financing activities of $69,301,000 was comprised of dividends paid of $69,232,000 and debt issuance costs of $69,000.

For the Nine Months Ended September 30, 2022

Cash and cash equivalents and restricted cash were $284,391,000 as of September 30, 2022, compared to $483,505,000 as of December 31, 2021, a decrease of $199,114,000. This decrease resulted from (i) $206,117,000 of net cash used in investing activities, (ii) $69,200,000 of net cash used in financing activities, partially offset by (iii) $76,203,000 of net cash provided by operating activities.

Net cash used in investing activities of $206,117,000 was comprised of the purchase of U.S. Treasury bills of $197,407,000 and construction in progress and real estate additions of $8,710,000.

Funds from Operations (“FFO”) (non-GAAP)

FFO is computed in accordance with the definition adopted by the Board of Governors of the National Association of Real Estate Investment Trusts (“NAREIT”). NAREIT defines FFO as GAAP net income or loss adjusted to exclude net gains from sales of certain real estate assets, real estate impairment losses, depreciation and amortization expense from real estate assets and other specified items, including the pro rata share of such adjustments of unconsolidated subsidiaries. FFO and FFO per diluted share are used by management, investors and analysts to facilitate meaningful comparisons of operating performance between periods and among our peers because it excludes the effect of real estate depreciation and amortization and net gains on sales, which are based on historical costs and implicitly assume that the value of real estate diminishes predictably over time, rather than fluctuating based on existing market conditions. FFO does not represent cash generated from operating activities and is not necessarily indicative of cash available to fund cash requirements and should not be considered as an alternative to net income as a performance measure or cash flow as a liquidity measure. FFO may not be comparable to similarly titled measures employed by other companies. A reconciliation of our net income to FFO is provided below.

FFO (non-GAAP) for the three and nine months ended September 30, 2023 and 2022

FFO (non-GAAP) for the three months ended September 30, 2023 was $18,623,000, or $3.63 per diluted share, compared to $22,544,000, or $4.40 per diluted share for the prior year’s three months.

FFO (non-GAAP) for the nine months ended September 30, 2023 was $55,464,000, or $10.81 per diluted share, compared to $66,451,000 or $12.96 per diluted share for the prior year’s nine months.

The following table reconciles our net income to FFO (non-GAAP):


	For the Three Months Ended September 30,				For the Nine Months Ended September 30,

(Amounts in thousands, except share and per share amounts)	2023		2022		2023		2022

Item 3.Quantitative and Qualitative Disclosures About Market Risk

We have exposure to fluctuations in interest rates, which are sensitive to many factors that are beyond our control. Our exposure to a change in interest rates is summarized in the table below.


	2023					2022
(Amounts in thousands, except per share amounts)	September 30, Balance		Weighted Average Interest Rate	Effect of 1% Change in Base Rates		December 31, Balance		Weighted Average Interest Rate
Variable Rate	$	702,544	5.88%	$	7,025	$	702,544	5.33%
Fixed Rate	394,000		1.97%	—		394,000		1.97%
	$	1,096,544	4.48%	$	7,025	$	1,096,544	4.12%

Total effect on diluted earnings per share				$	1.37

We have an interest rate cap relating to the mortgage loan on the office condominium of our 731 Lexington Avenue property with a notional amount of $500,000,000 that capped LIBOR at 6.00% through July 15, 2023 and caps the Prime Rate (8.50% as of September 30, 2023) at 6.00% through loan maturity.

We have an interest rate cap relating to the mortgage loan on Rego Park II shopping center with a notional amount of $202,544,000 that caps SOFR at 4.15% through November 2024.

We have an interest rate swap relating to the mortgage loan on the retail condominium of our 731 Lexington Avenue property with a notional amount of $300,000,000 that swaps SOFR plus 1.51% for a fixed rate of 1.76% through May 2025.

Fair Value of Debt

The fair value of our mortgages payable is calculated by discounting the future contractual cash flows of these instruments using current risk-adjusted rates available to borrowers with similar credit ratings, which are provided by a third-party specialist. As of September 30, 2023 and December 31, 2022, the estimated fair value of our mortgages payable was $1,064,832,000 and $1,061,221,000, respectively. Our fair value estimates, which are made at the end of the reporting period, may be different from the amounts that may ultimately be realized upon the disposition of our financial instruments.

Item 4.Controls and Procedures

(a) Disclosure Controls and Procedures: Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, our disclosure controls and procedures are effective.

(b) Internal Control Over Financial Reporting: There have not been any changes in our internal control over financial reporting during the fiscal quarter to which this Quarterly Report on Form 10-Q relates that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Recently Issued Accounting Literature	Recently Issued Accounting LiteratureIn March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04 establishing Accounting Standards Codification (“ASC”) Topic 848, Reference Rate Reform, and in January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope (collectively, “ASC 848”). ASC 848 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASC 848 is optional and may be elected over time as reference rate reform activities occur. We have elected to apply the hedge accounting expedients related to probability and the 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. In December 2022, the FASB issued ASU 2022-06, Deferral of the Sunset Date of Topic 848 (“ASU 2022-06”) which was issued to defer the sunset date of ASC 848 to December 31, 2024. ASU 2022-06 is effective immediately for all companies. As of September 30, 2023, we have transitioned all of our LIBOR-indexed debt and derivatives and, for our derivatives in hedge accounting relationships, utilized the elective relief in ASC 848, allowing for the continuation of hedge accounting through the transition process.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation We account for stock-based compensation in accordance with ASC Topic 718, Compensation – Stock Compensation (“ASC 718”). Our 2016 Omnibus Stock Plan (the “Plan”) provides for grants of incentive and non-qualified stock options, restricted stock, stock appreciation rights, deferred stock units (“DSUs”) and performance shares, as defined, to the directors, officers and employees of the Company and Vornado. In May 2023, we granted each of the members of our Board of Directors 449 DSUs with a market value of $75,000 per grant. The grant date fair value of these awards was $56,250 per grant, or $450,000 in the aggregate, in accordance with ASC 718. The DSUs entitle the holders to receive shares of the Company’s common stock without the payment of any consideration. The DSUs vested immediately and accordingly, were expensed on the date of grant, but the shares of common stock underlying the DSUs are not deliverable to the grantee until the grantee is no longer serving on the Company’s Board of Directors. As of September 30, 2023, there were 23,388 DSUs outstanding and 482,399 shares were available for future grant under the Plan.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Insurance We maintain general liability insurance with limits of $300,000,000 per occurrence and per property, of which the first $30,000,000 includes communicable disease coverage, and all-risk property and rental value insurance coverage with limits of $1.7 billion per occurrence, including coverage for acts of terrorism, with sub-limits for certain perils such as floods and earthquakes on each of our properties and excluding communicable disease coverage. Fifty Ninth Street Insurance Company, LLC (“FNSIC”), our wholly owned consolidated subsidiary, acts as a direct insurer for coverage for acts of terrorism, including nuclear, biological, chemical and radiological (“NBCR”) acts, as defined by the Terrorism Risk Insurance Act of 2002, as amended to date and which has been extended through December 2027. Coverage for acts of terrorism (including NBCR acts) is up to $1.7 billion per occurrence and in the aggregate. Coverage for acts of terrorism (excluding NBCR acts) is fully reinsured by third party insurance companies and the Federal government with no exposure to FNSIC. For NBCR acts, FNSIC is responsible for a $316,000 deductible and 20% of the balance of a covered loss, and the Federal government is responsible for the remaining 80% of a covered loss. We are ultimately responsible for any loss incurred by FNSIC. We continue to monitor the state of the insurance market and the scope and costs of coverage for acts of terrorism or other events. However, we cannot anticipate what coverage will be available on commercially reasonable terms in the future. We are responsible for uninsured losses and for deductibles and losses in excess of our insurance coverage, which could be material. The principal amounts of our mortgage loans are non-recourse to us and the loans contain customary covenants requiring us to maintain insurance. Although we believe that we have adequate insurance coverage for purposes of these agreements, we may not be able to obtain an equivalent amount of coverage at reasonable costs in the future. If lenders insist on greater coverage than we are able to obtain, it could adversely affect our ability to finance or refinance our properties. Letters of Credit Approximately $900,000 of standby letters of credit were issued and outstanding as of September 30, 2023. Other There are various legal actions brought against us from time-to-time in the ordinary course of business. In our opinion, the outcome of such pending matters in the aggregate will not have a material effect on our financial position, results of operations or cash flows.

Earnings Per Share

Earnings Per ShareThe following table sets forth the computation of basic and diluted income per share, including a reconciliation of net income and the number of shares used in computing basic and diluted income per share. Basic income per share is determined using the weighted average shares of common stock (including deferred stock units) outstanding during the period. Diluted income per share is determined using the weighted average shares of common stock (including deferred stock units) outstanding during the period, and assumes all potentially dilutive securities were converted into common shares at the earliest date possible. There were no potentially dilutive securities outstanding during the three and nine months ended September 30, 2023 and 2022.

Fair Value Measurement	ASC Topic 820, Fair Value Measurement (“ASC 820”) defines fair value and establishes a framework for measuring fair value. ASC 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 – quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities as well as certain U.S. Treasury securities that are highly liquid and are actively traded in secondary markets; Level 2 – observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 – unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as consider counterparty credit risk in our assessment of fair value.
