EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended September 30, 2024 of SL Green Realty Corp. and SL Green Operating Partnership, L.P. Unless stated otherwise or the context otherwise requires, references to "SL Green Realty Corp.," the "Company" or "SL Green" mean SL Green Realty Corp. and its consolidated subsidiaries, including SL Green Operating Partnership, L.P.; and references to "SL Green Operating Partnership, L.P.," the "Operating Partnership" or "SLGOP" mean SL Green Operating Partnership, L.P. and its consolidated subsidiaries. The terms "we," "our" and "us" mean the Company and all the entities owned or controlled by the Company, including the Operating Partnership.

The Company is a Maryland corporation which operates as a self-administered and self-managed real estate investment trust, or REIT, and is the sole managing general partner of the Operating Partnership. As a general partner of the Operating Partnership, the Company has full, exclusive and complete responsibility and discretion in the day-to-day management and control of the Operating Partnership.

As of September 30, 2024, the Company owns 93.58% of the outstanding general and limited partnership interest in the Operating Partnership and owns 9,200,000 Series I Preferred Units of the Operating Partnership. As of September 30, 2024, noncontrolling investors held, in aggregate, a 6.42% limited partnership interest in the Operating Partnership. We refer to these interests as the noncontrolling interests in the Operating Partnership.

The Company and the Operating Partnership are managed and operated as one entity. The financial results of the Operating Partnership are consolidated into the financial statements of the Company. The Company has no significant assets other than its investment in the Operating Partnership. Substantially all of our assets are held by, and our operations are conducted through, the Operating Partnership. Therefore, the assets and liabilities of the Company and the Operating Partnership are substantially the same.

Noncontrolling interests in the Operating Partnership, stockholders' equity of the Company and partners' capital of the Operating Partnership are the main areas of difference between the consolidated financial statements of the Company and those of the Operating Partnership. The common limited partnership interests in the Operating Partnership not owned by the Company are accounted as noncontrolling interests, within mezzanine equity, in the Company's and the Operating Partnership's consolidated financial statements.

We believe combining the quarterly reports on Form 10-Q of the Company and the Operating Partnership into this single report results in the following benefits:

•Combined reports enhance investors' understanding of the Company and the Operating Partnership by enabling investors to view the business as a whole in the same manner as management views and operates the business;

•Combined reports eliminate duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the Company's disclosure applies to both the Company and the Operating Partnership; and

•Combined reports create time and cost efficiencies through the preparation of one combined report instead of two separate reports.

To help investors understand the significant differences between the Company and the Operating Partnership, this report presents the following separate sections for each of the Company and the Operating Partnership:

•consolidated financial statements; and

•the following notes to the consolidated financial statements:

◦Note 11, Noncontrolling Interests on the Company’s Consolidated Financial Statements;

◦Note 12, Stockholders' Equity of the Company; and

◦Note 13, Partners' Capital of the Operating Partnership.

This report also includes separate Part I, Item 4. Controls and Procedures sections and separate Exhibit 31 and 32 certifications for each of the Company and the Operating Partnership, respectively, in order to establish that the Chief Executive Officer and the Chief Financial Officer of the Company, in both their capacity as the principal executive officer and principal financial officer of the Company and the principal executive officer and principal financial officer of the general partner of the Operating Partnership, have made the requisite certifications and that the Company and the Operating Partnership are compliant with Rule 13a-15 and Rule 15d-15 of the Securities Exchange Act of 1934, as amended, or the Exchange Act.

1. Organization and Basis of Presentation

SL Green Realty Corp., which is referred to as the Company or SL Green, a Maryland corporation, and SL Green Operating Partnership, L.P., which is referred to as SLGOP or the Operating Partnership, a Delaware limited partnership, were formed in June 1997 for the purpose of combining the commercial real estate business of S.L. Green Properties, Inc. and its affiliated partnerships and entities. The Operating Partnership received a contribution of interest in the real estate properties, as well as 95% of the economic interest in the management, leasing and construction companies which are referred to as S.L. Green Management Corp, or the Service Corporation. All of the management, leasing and construction services that are provided to the properties that are wholly-owned by us and that are provided to certain joint ventures are conducted through SL Green Management LLC and S.L. Green Management Corp., respectively, which are 100% owned by the Operating Partnership. The Company has qualified, and expects to qualify in the current fiscal year, as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended, or the Code, and operates as a self-administered, self-managed REIT. A REIT is a legal entity that holds real estate interests and, through payments of dividends to stockholders, is permitted to minimize the payment of Federal income taxes at the corporate level. Unless the context requires otherwise, all references to "we," "our" and "us" means the Company and all entities owned or controlled by the Company, including the Operating Partnership.

Substantially all of our assets are held by, and all of our operations are conducted through, the Operating Partnership. The Company is the sole managing general partner of the Operating Partnership. As of September 30, 2024, noncontrolling investors held, in the aggregate, a 6.42% limited partnership interest in the Operating Partnership. We refer to these interests as the noncontrolling interests in the Operating Partnership. The Operating Partnership is considered a variable interest entity, or VIE, in which we are the primary beneficiary. See Note 11, "Noncontrolling Interests on the Company's Consolidated Financial Statements."

On September 30, 2024, we owned the following interests in properties in the New York metropolitan area, primarily in midtown Manhattan. Our investments located outside of Manhattan are referred to as the Suburban properties:

(1)The weighted average leased occupancy for commercial properties represents the total leased square footage divided by the total square footage at acquisition. The weighted average leased occupancy for residential properties represents the total leased units divided by the total available units. Properties under construction are not included in the calculation of weighted average leased occupancy.

(2)As of September 30, 2024, we owned a building at 7 Dey Street / 185 Broadway that was comprised of approximately 140,382 square feet (unaudited) of residential space and approximately 50,206 square feet (unaudited) of office and retail space that is under development. For the purpose of this report, we have included this building in the number of residential properties we own. However, we have included only the residential square footage in the residential approximate square footage, and have listed the balance of the square footage as development square footage.

(unaudited)

As of September 30, 2024, we also managed one office building and one retail building owned by third parties encompassing approximately 0.4 million square feet (unaudited), and held debt and preferred equity investments with a book value of $293.9 million, excluding debt and preferred equity investments and other financing receivables totaling $9.3 million that are included in balance sheet line items other than the Debt and preferred equity investments line item.

Partnership Agreement

In accordance with the partnership agreement of the Operating Partnership, or the Operating Partnership Agreement, we allocate all distributions and profits and losses in proportion to the percentage of ownership interests of the respective partners, subject to the priority distributions with respect to preferred units and special provisions that apply to Long Term Incentive Plan ("LTIP") Units. As the managing general partner of the Operating Partnership, we are required to take such reasonable efforts, as determined by us in our sole discretion, to cause the Operating Partnership to distribute sufficient amounts to enable the payment of sufficient dividends by us to minimize any Federal income or excise tax at the Company level. Under the Operating Partnership Agreement, each limited partner has the right to redeem units of limited partnership interests for cash, or if we so elect, shares of SL Green's common stock on a one-for-one basis.

Basis of Quarterly Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of the financial position of the Company and the Operating Partnership at September 30, 2024 and the results of operations for the periods presented have been included. The operating results for the period presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. These financial statements should be read in conjunction with the financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2023 of the Company and the Operating Partnership.

The consolidated balance sheet at December 31, 2023 has been derived from the audited financial statements as of that date but does not include all the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

2. Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include our accounts and those of our subsidiaries, which are wholly-owned or controlled by us. Entities which we do not control through our voting interest, but have significant influence over, and entities which are variable interest entities, but where we are not the primary beneficiary, are accounted for under the equity method. See Note 5, "Debt and Preferred Equity Investments" and Note 6, "Investments in Unconsolidated Joint Ventures."

We consolidate a VIE in which we are considered the primary beneficiary. The primary beneficiary 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.

All significant intercompany balances and transactions have been eliminated.

Investment in Commercial Real Estate Properties

We allocate the purchase price of real estate to land and building (inclusive of tenant improvements) and, if determined to be material, intangibles, such as the value of above- and below-market leases and origination costs associated with the in-place leases. We depreciate the amount allocated to building (inclusive of tenant improvements) over their estimated useful lives, which generally range from 3 years to 40 years. We amortize the amount allocated to the above- and below-market leases over the remaining term of the associated lease, which generally range from 1 year to 15 years, and record it as either an increase (in the case of below-market leases) or a decrease (in the case of above-market leases) to rental income. We amortize the amount allocated to the values associated with in-place leases over the expected term of the associated lease, which generally ranges from 1 year to 15 years. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off. Origination costs are amortized as an expense over the remaining life of the lease and tenant improvements are amortized over the shorter of the remaining life of the lease or useful life of the improvement (or charged against earnings if the lease is terminated prior to its contractual expiration date). When allocating the purchase price of real estate, we assess fair value of the leases based on estimated cash flow projections that utilize appropriate discount rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and market/economic conditions that may affect the property. To the extent acquired leases contain fixed rate renewal options that are below-market and determined to be material, we amortize such below-market lease value into rental income over the renewal period.

The Company classifies those leases under which the Company is the lessee at lease commencement as finance or operating leases. Leases qualify as finance leases if the lease transfers ownership of the asset at the end of the lease term, the lease grants an option to purchase the asset that we are reasonably certain to exercise, the lease term is for a major part of the remaining economic life of the asset, or the present value of the lease payments equals or exceeds substantially all of the fair value of the underlying asset. Leases that do not qualify as finance leases are deemed to be operating leases. At lease commencement the Company records a lease liability which is measured as the present value of the lease payments and a right of use asset which is measured as the amount of the lease liability and any initial direct costs incurred. The Company applies a discount rate to determine the present value of the lease payments. If the rate implicit in the lease is known, the Company uses that rate. If the rate implicit in the lease is not known, the Company uses a discount rate reflective of the Company’s collateralized borrowing rate given the term of the lease. To determine the discount rate, the Company employs a third-party specialist to develop an analysis based primarily on the observable borrowing rates of the Company, other REITs, and other corporate borrowers with long-term borrowings. On the consolidated statements of operations, operating leases are expensed through operating lease rent while financing leases are expensed through amortization and interest expense. When applicable, the Company combines the consideration for lease and non-lease components in the calculation of the value of the lease obligation and right-of-use asset.

On a quarterly basis, or when events or changes in circumstances arise, we assess whether there are any indications that the value of our real estate consolidated properties may be impaired or that their carrying value may not be recoverable. A consolidated property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted) and terminal value to be generated by the property is less than the carrying value of the property. To the extent impairment has occurred, the loss will be measured as the excess of the carrying amount of the property over the fair value of the property as calculated in accordance with Accounting Standards Codification, or ASC 820. We also evaluate our real estate consolidated properties for impairment when a property has been classified as held for sale. Real estate assets held for sale are valued at the lower of their carrying value or fair value less costs to sell and depreciation expense is no longer recorded.

In April 2024, the Company entered into an agreement to sell the property at 719 Seventh Avenue for $30.5 million. As a result of the pending sale, the Company recorded a $46.3 million charge to reduce the carrying value of its investment to the contracted purchase price for the three months ended March 31, 2024, which is included in Depreciable real estate reserves and impairments in the consolidated statements of operations. The transaction closed during the second quarter of 2024. See Note 4, "Properties Held for Sale and Property Dispositions."

During the nine months ended September 30, 2024, the Company recorded a $13.7 million charge, reflective of $13.2 million of capitalized interest, to reduce the carrying value of the residential condominium units at 760 Madison Avenue, based on the total of the sales contracts that the Company entered into for these units. This charge is included in Depreciable real estate reserves and impairments in the consolidated statements of operations. The transactions are expected to close in the fourth quarter of 2024.

(unaudited)

For the three and nine months ended September 30, 2024, we recognized a reduction of rental revenue of ($0.8 million) and ($1.7 million), respectively, for the amortization of aggregate above-market leases in excess of below-market leases resulting from the allocation of the purchase price of the applicable properties. For the three months ended September 30, 2023, we recognized a reduction in rental revenue of ($0.1 million) for the amortization of aggregate above-market leases in excess of below-market leases. For the nine months ended September 30, 2023, we recognized additional rental revenue of $14.3 million for the amortization of aggregate below-market leases in excess of above-market leases.

The following summarizes our identified intangible assets (acquired above-market leases and in-place leases) and intangible liabilities (acquired below-market leases) as of September 30, 2024 and December 31, 2023 (in thousands):


	September 30, 2024		December 31, 2023
Identified intangible assets (included in other assets):
Gross amount	$	273,010	$	189,680
Accumulated amortization	(193,327)		(184,902)
Net	$	79,683	$	4,778
Identified intangible liabilities (included in deferred revenue):
Gross amount	$	226,034	$	205,394
Accumulated amortization	(203,459)		(202,089)
Net	$	22,575	$	3,305

Cash and Cash Equivalents

We consider all highly liquid investments with maturity of three months or less when purchased to be cash equivalents.

Restricted Cash

Restricted cash primarily consists of security deposits held on behalf of our tenants, interest reserves, as well as capital improvement and real estate tax escrows required under certain loan agreements.

Fair Value Measurements

See Note 16, "Fair Value Measurements."

Investment in Marketable Securities

At acquisition, we designate a debt security as held-to-maturity, available-for-sale, or trading. As of September 30, 2024, we did not have any debt securities designated as held-to-maturity or trading. We account for our available-for-sale securities at fair value pursuant to ASC 820-10, with the net unrealized gains or losses reported as a component of accumulated other comprehensive income or loss. The cost of marketable securities sold and the amount reclassified out of accumulated other comprehensive income into earnings is determined using the specific identification method. Credit losses are recognized in accordance with ASC 326. We account for equity marketable securities at fair value pursuant to ASC 820-10, with the net unrealized gains or losses reported in net income.

As of September 30, 2024 and December 31, 2023, we held the following marketable securities (in thousands):


	September 30, 2024		December 31, 2023
Commercial mortgage-backed securities	$	16,522	$	9,591



Total investment in marketable securities	$	16,522	$	9,591

The cost basis of the commercial mortgage-backed securities ("CMBS") was $16.9 million and $11.5 million as of September 30, 2024 and December 31, 2023, respectively. These securities mature at various times through 2030. As of September 30, 2024, one security was in an unrealized gain position of $0.1 million with a fair market value of $5.4 million, and two securities were in an unrealized loss position of $0.9 million with a fair market value of $11.1 million with one of the securities being in a continuous unrealized loss position for more than 12 months. All securities were in an unrealized loss position as of December 31, 2023 with an unrealized loss of $1.9 million, a fair market value of $9.6 million and were in a continuous unrealized loss position for more than 12 months. We do not intend to sell our other securities, and it is more likely than not that we will not be required to sell the investments before recovery of their amortized cost bases.

We did not dispose of any debt marketable securities during the three and nine months ended September 30, 2024 and 2023.

We held no equity marketable securities as of September 30, 2024 and December 31, 2023.

Investment in CMBS Securitization Trusts

We may acquire securities in CMBS securitization trusts and, which in certain cases, we may be contracted to provide special servicing activities for these trusts. In certain cases, we may acquire the controlling class of the trust and we may have the right to name and remove the special servicer for these trusts. These circumstances may result in our consolidating the securitization trusts on our financial statements. We evaluate all of our positions and special servicer appointments for consolidation, which are considered to be VIEs to the Company.

As the special servicer, we provide services on defaulted loans within the trusts as permitted by the underlying contractual agreements. We receive a fee in exchange for these services. The rights provided to us as special servicer give us the ability to direct activities that could significantly impact the trust's economic performance, which requires consolidation of the securitization trust unless a third party has the right to unilaterally remove us as special servicer without cause. In such instances where we can be removed as special servicer without cause, we do not have the power to direct activities that most significantly impact the trust's economic performance and would not consolidate the securitization trust.

For CMBS securitization trusts in which we are determined to be the primary beneficiary, we consolidate the securitization trusts on our consolidated balance sheets. The consolidation of such securitization trusts results in a gross presentation of the underlying collateral loans as assets as well as the senior CMBS positions owned by third parties, which are presented as liabilities on our consolidated balance sheets. The assets of the consolidated securitization trust can only be used to satisfy the liabilities of that securitization and are not available to the Company for any other purpose. Additionally, the senior CMBS securitization trust obligations can only be satisfied through repayment of the underlying collateral loans as they do not have any recourse to the Company or our assets. The Company has not provided any guarantees with respect to the performance or repayment of the senior CMBS obligations.

While consolidation of the securitization trust increases the gross presentation of our consolidated balance sheets, it does not impact the economic exposure or performance of the Company as it is limited to that of the actual investment in the CMBS securitization trust, and not the consolidated senior obligations.

As of September 30, 2024 and December 31, 2023, we consolidated the following CMBS securitization trusts (in thousands):

(1)Includes $126.4 million and $32.2 million of assets and liabilities, respectively, for a loan that is on non-accrual and is accounted for on an amortized cost basis.

(2)Includes $3.4 million of accrued interest income.

(3)The Company is in discussions with the respective borrowers on the resolution of the past maturities.

(4)Includes $2.3 million of accrued interest expense.

We have elected to record the associated interest income and interest expense for these investments as separate line items on our consolidated statements of operations. The amounts recorded in Interest income from real estate loans held by consolidated securitization vehicles on our consolidated statements of operations include the Company's interest income as well as the interest income associated with CMBS positions owned by third parties, which is offset by the amounts recorded in Interest expense on senior obligations of consolidated securitization vehicles on our consolidated statements of operations. As a result, the net impact is limited to the interest income on the CMBS securities we own directly and not the gross consolidated interest income and interest expense.

Investments in Unconsolidated Joint Ventures

We assess our investments in unconsolidated joint ventures for recoverability and if it is determined that a loss in value of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments for impairment based on each joint ventures' actual and projected cash flows. Aside from charges noted in Note 6, "Investments in Unconsolidated Joint Ventures," we do not believe that the values of any of our equity investments were impaired at September 30, 2024.

Deferred Lease Costs

Deferred lease costs consist of incremental fees and direct costs that would not have been incurred if the lease had not been obtained and are amortized on a straight-line basis over the related lease term.

Lease Classification

Lease classification for leases under which the Company is the lessor is evaluated at lease commencement and leases not classified as sales-type leases or direct financing leases are classified as operating leases. Leases qualify as sales-type leases if the contract includes either transfer of ownership clauses, certain purchase options, a lease term representing a major part of the economic life of the asset, or the present value of the lease payments and residual guarantees provided by the lessee exceeds substantially all of the fair value of the asset. Additionally, leasing an asset so specialized that it is not deemed to have any value to the Company at the end of the lease term may also result in classification as a sales-type lease. Leases qualify as direct financing leases when the present value of the lease payments and residual value guarantees provided by the lessee and unrelated third parties exceeds substantially all of the fair value of the asset and collection of the payments is probable.

Revenue Recognition

Rental revenue for operating leases is recognized on a straight-line basis over the term of the lease. Rental revenue recognition commences when the leased space is available for its intended use by the lessee.

To determine whether the leased space is available for its intended use by the lessee, management evaluates whether we or the tenant are the owner of tenant improvements for accounting purposes. When management concludes that we are the owner of tenant improvements, rental revenue recognition begins when the tenant takes possession of the finished space, which is when such tenant improvements are substantially complete. In certain instances, when management concludes that we are not the owner of tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the space.

The excess of rents recognized over amounts contractually due pursuant to the underlying leases are included in deferred rents receivable on the consolidated balance sheets.

In addition to base rent, our tenants also generally will pay variable rent, which represents their pro rata share of increases in real estate taxes and certain operating expenses for the building over a base year. In some leases, in lieu of paying additional rent based upon increases in certain building operating expenses, the tenant will pay additional rent based upon increases in the wage rate paid to porters over the porters' wage rate in effect during a base year or increases in the consumer price index over the index value in effect during a base year. In addition, many of our leases contain fixed percentage increases over the base rent to cover escalations. Electricity is most often supplied by the landlord either on a sub-metered basis, or rent inclusion basis (i.e., a fixed fee is included in the rent for electricity, which amount may increase based upon increases in electricity rates or increases in electrical usage by the tenant). Base building services other than electricity (such as heat, air conditioning and freight elevator service during business hours, and base building cleaning) are typically provided at no additional cost, with the tenant paying additional rent only for services which exceed base building services or for services which are provided outside normal business hours. These escalations are based on actual expenses incurred in the prior calendar year. If the expenses in the current year are different from those in the prior year, then during the current year, the escalations will be adjusted to reflect the actual expenses for the current year.

Rental revenue is recognized if collectability is probable. If collectability of substantially all of the lease payments is assessed as not probable, any difference between the rental revenue recognized to date and the lease payments that have been collected is recognized as a current-period adjustment to rental revenue. A subsequent change in the assessment of collectability to probable may result in a current-period adjustment to rental revenue for any difference between the rental revenue that would have been recognized if collectability had always been assessed as probable and the rental revenue recognized to date.

The Company provides its tenants with certain customary services for lease contracts such as common area maintenance and general security. We have elected to combine the non-lease components with the lease components of our operating lease agreements and account for them as a single lease component in accordance with ASC 842.

We record a gain or loss on sale of real estate assets when we no longer have a controlling financial interest in the entity owning the real estate, a contract exists with a third party and that third party has control of the assets acquired.

Investment income on debt and preferred equity investments is accrued based on the contractual terms of the instruments and when it is deemed collectible. Some debt and preferred equity investments provide for accrual of interest at specified rates, which differ from current payment terms. Interest is recognized on such loans at the accrual rate subject to management's determination that accrued interest is collectible. If management cannot make this determination, interest income above the current pay rate is recognized only upon actual receipt.

Deferred origination fees, original issue discounts and loan origination costs, if any, are recognized as an adjustment to interest income over the terms of the related investments using the effective interest method. Fees received in connection with loan commitments are also deferred until the loan is funded and are then recognized over the term of the loan as an adjustment to yield. Discounts or premiums associated with the purchase of loans are amortized or accreted into interest income as a yield adjustment on the effective interest method based on expected cash flows through the expected maturity date of the related investment. If we purchase a debt or preferred equity investment at a discount, intend to hold it until maturity and expect to recover the full value of the investment, we accrete the discount into income as an adjustment to yield over the term of the investment. If we purchase a debt or preferred equity investment at a discount with the intention of foreclosing on the collateral, we do not accrete the discount. For debt investments acquired at a discount for credit quality, the difference between contractual cash flows and expected cash flows at acquisition is not accreted. Anticipated exit fees, the collection of which is expected, are also recognized over the term of the loan as an adjustment to yield.

We consider a debt and preferred equity investment to be past due when amounts contractually due have not been paid. Debt and preferred equity investments are placed on a non-accrual status at the earlier of the date at which payments become 90 days past due or when, in the opinion of management, a full recovery of interest income becomes doubtful. Interest income recognition is resumed on any debt or preferred equity investment that is on non-accrual status when such debt or preferred equity investment becomes contractually current and performance is demonstrated to be resumed.

We may syndicate a portion of the loans that we originate or sell the loans individually. When a transaction meets the criteria for sale accounting, we recognize gain or loss based on the difference between the sales price and the carrying value of the loan sold. Any related unamortized deferred origination fees, original issue discounts, loan origination costs, discounts or premiums at the time of sale are recognized as an adjustment to the gain or loss on sale, which is included in investment income on the consolidated statement of operations. Any fees received at the time of sale or syndication are recognized as part of investment income.

Asset management fees are recognized on a straight-line basis over the term of the asset management agreement.

Revenues from the sale of SUMMIT tickets are recognized upon admission or ticket expirations. Deferred revenue related to unused and unexpired tickets as of September 30, 2024 and December 31, 2023 was $3.8 million and $2.6 million, respectively, and is included in Deferred revenue on the consolidated balance sheets.

Debt and Preferred Equity Investments

Debt and preferred equity investments are presented at the net amount expected to be collected in accordance with ASC 326. An allowance for loan losses is deducted from the amortized cost basis of the financial assets to present the net carrying value at the amount expected to be collected through the expected maturity date of such investments. The expense for loan loss and other investment reserves is the charge to earnings to adjust the allowance for loan losses to the appropriate level. Amounts are written off from the allowance when we de-recognize the related investment either as a result of a sale of the investment or acquisition of equity interests in the collateral.

The Company evaluates the amount expected to be collected based on current market and economic conditions, historical loss information, and reasonable and supportable forecasts. The Company's assumptions are derived from both internal data and external data which may include, among others, governmental economic projections for the New York City Metropolitan area, public data on recent transactions and filings for securitized debt instruments. This information is aggregated by asset class and adjusted for duration. Based on these inputs, loans are evaluated at the individual asset level. In certain instances, we may also use a probability-weighted model that considers the likelihood of multiple outcomes and the amount expected to be collected for each outcome.

The evaluation of the possible credit deterioration associated with the performance and/or value of the underlying collateral property as well as the financial and operating capability of the borrower/sponsor requires significant judgment, which include both asset level and market assumptions over the relevant time period.

In addition, quarterly, the Company assigns each loan a risk rating. Based on a 3-point scale, loans are rated “1” through “3,” from lower risk to higher risk, which ratings are defined as follows: 1 - Low Risk Assets - Low probability of loss, 2 - Watch List Assets - Higher potential for loss, 3 - High Risk Assets - Loss more likely than not. Loans with risk ratings of 2 or above are evaluated to determine whether the expected risk of loss is appropriately captured through the combination of our expectations of current conditions, historical loss information and supportable forecasts described above or whether risk characteristics specific to the loan warrant the use of a probability-weighted model.

Financing investments that are classified as held for sale are carried at the expected amount to be collected or fair market value using available market information obtained through consultation with dealers or other originators of such investments as well as discounted cash flow models based on Level 3 data pursuant to ASC 820-10. As circumstances change, management may conclude not to sell an investment designated as held for sale. In such situations, the investment will be reclassified at its expected amount to be collected.

Other financing receivables that are included in balance sheet line items other than the Debt and preferred equity investments line are also measured at the net amount expected to be collected.

Accrued interest receivable amounts related to these debt and preferred equity investment and other financing receivables are recorded at the net amount expected to be collected within Other assets in the consolidated balance sheets. Accrued interest receivables that are written off are recognized as an expense in loan loss and other investment reserves.

Income Taxes

SL Green is taxed as a REIT under Section 856(c) of the Code. As a REIT, SL Green generally is not subject to Federal income tax. To maintain its qualification as a REIT, SL Green must distribute at least 90% of its REIT taxable income to its stockholders and meet certain other requirements. If SL Green fails to qualify as a REIT in any taxable year, SL Green will be subject to Federal income tax on its taxable income at regular corporate rates. SL Green may also be subject to certain state, local and franchise taxes. Under certain circumstances, Federal income and excise taxes may be due on its undistributed taxable income.

The Operating Partnership is a partnership and, as a result, all income and losses of the partnership are allocated to the partners for inclusion in their respective income tax returns. The only provision for income taxes included in the consolidated statements of operations relates to the Operating Partnership’s consolidated taxable REIT subsidiaries. The Operating Partnership may also be subject to certain state, local and franchise taxes.

We have elected, and may elect in the future, to treat certain of our corporate subsidiaries as taxable REIT subsidiaries, or TRSs. In general, TRSs may perform non-customary services for the tenants of the Company, hold assets that we cannot hold directly and generally may engage in any real estate or non-real estate related business. The TRSs generate income, resulting in Federal, state and local corporate tax liability for these entities. During the three and nine months ended September 30, 2024, we recorded Federal, state and local tax provisions totaling $1.1 million and $2.7 million, respectively, for these entities. During the three and nine months ended September 30, 2023, we recorded Federal, state and local tax provisions totaling $2.5 million and $5.2 million, respectively, for these entities.

SUMMIT is held in a TRS and pays Federal, state and local taxes. During the three and nine months ended September 30, 2024, we recorded Federal, state and local tax benefits for SUMMIT of $1.8 million and $1.2 million, respectively. During the three and nine months ended September 30, 2023, we recorded Federal, state and local tax expense for SUMMIT of $3.7 million and $6.9 million, respectively.

We follow a two-step approach for evaluating uncertain tax positions. Recognition (step one) occurs when an enterprise concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustained upon examination. Measurement (step two) determines the amount of benefit that is more-likely-than-not to be realized upon settlement. Derecognition of a tax position that was previously recognized would occur when a company subsequently determines that a tax position no longer meets the more-likely-than-not threshold of being sustained. The use of a valuation allowance as a substitute for derecognition of tax positions is prohibited.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash investments, debt and preferred equity investments and accounts receivable. We place our cash investments with high quality financial institutions. The collateral securing our debt and preferred equity investments is located in New York City. See Note 5, "Debt and Preferred Equity Investments."

We perform initial and ongoing evaluations of the credit quality of our tenants and require most tenants to provide security deposits or letters of credit. Though these security deposits and letters of credit are insufficient to meet the total value of a tenant's lease obligation, they are a measure of good faith and a potential source of funds to offset the economic costs associated with lost revenue from that tenant and the costs associated with re-tenanting a space. The properties in our real estate portfolio are located in the New York metropolitan area, principally in Manhattan. Our tenants operate in various industries. Other than one tenant, Paramount Global (formerly ViacomCBS Inc.), which accounted for 5.5% of our share of annualized cash rent as of September 30, 2024, no other tenant in our portfolio accounted for more than 5.0% of our share of annualized cash rent, including our share of joint venture annualized cash rent, for the three months ended September 30, 2024.

For the three months ended September 30, 2024, the following properties contributed more than 5.0% of our annualized cash rent from office properties, including our share of annualized cash rent from joint venture office properties:


Property			Three months ended September 30, 2024
One Vanderbilt Avenue			17.2%
11 Madison Avenue			8.7%
420 Lexington Ave			7.0%
1515 Broadway			6.7%
245 Park Avenue			6.0%
1185 Avenue of the Americas			5.9%
280 Park Avenue			5.1%

Reclassification

Certain prior year balances have been reclassified to conform to our current year presentation.

Beginning in the second quarter of 2024, we reclassified amounts recorded for certain right-of-use assets classified as operating leases from a gross presentation above accumulated depreciation to a net presentation below accumulated depreciation in our consolidated balance sheets. This includes reclassifying the related amortization that was previously included in the accumulated depreciation. We believe this presentation enhances the Company's financial statements.

As of December 31, 2023, SUMMIT met the criteria of a reportable operating segment pursuant to the guidance in ASC 280. Accordingly, we reclassified SUMMIT Operator revenue, SUMMIT Operator expenses, and SUMMIT Operator tax expense to separate financial statement line items in our consolidated statements of operations. These items were previously presented on a net basis in Other income. Additionally, the depreciation and amortization of SUMMIT assets are included in Depreciation and amortization in our consolidated statements of operations. Prior period balances have been reclassified to conform to the current period presentation.

Accounting Standards Updates

In December 2023, the FASB issued ASU No. 2023-09 Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. The objective of the amendments in ASU 2023-09 related to the rate reconciliation and income taxes paid disclosures are to improve transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation, and income taxes paid disaggregated by jurisdiction. The amendment will require that public entities on an annual basis disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. Additionally, the amendment will require that all entities disclose on an annual basis the amount of taxes paid (net of refunds received) disaggregated by federal, state and foreign taxes as well as disaggregated by individual jurisdictions that meet a quantitative threshold. ASU 2023-09 is effective prospectively for annual periods beginning after December 15, 2024. Early adoption and retrospective application is permitted. We are currently evaluating the impact of the adoption of ASU 2023-09 on our consolidated financial statements, but do not believe the adoption of this standard will have a material impact on our consolidated financial statements.

In November 2023, the FASB issued ASU No. 2023-07 Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. ASU 2023-07 amends the reportable segment disclosure requirements to enhance disclosures about significant segment expenses. The objective of the amendment is to improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision-useful financial analyses. The amendment will require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss (collectively referred to as the "significant expense principle"). Additionally, the amendment will require an entity to disclose an amount for "other segment items" by reportable segment and a description of its composition as well as require annual disclosures about a reportable segment's profit or loss and assets currently required by Topic 280 in interim periods. Lastly, the amendment will require a public entity to disclose the title and position of the CODM and an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding to allocate resources. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and should be applied retrospectively to all prior periods presented in the financial statements. We are currently evaluating the impact of the adoption of ASU 2023-07 on our consolidated financial statements, but do not believe the adoption of this standard will have a material impact on our consolidated financial statements.

In August 2023, the FASB issued ASU No. 2023-05 Business Combinations - Joint Venture Formations (Subtopic 805-60) Recognition and Initial Measurement. ASU 2023-05 addresses the accounting for contributions made to a joint venture, upon formation, in a joint venture's separate financial statements. The objectives of the amendments are to provide decision-useful information to investors and other allocators of capital in a joint venture's financial statements and reduce diversity in practice. The amendments require that a joint venture apply the following key adaptations from the business combinations guidance upon formation: (i) a joint venture is the formation of a new entity without an accounting acquirer, (ii) a joint venture measures its identifiable net assets and goodwill, if any, at the formation date, (iii) initial measurement of a joint venture's total net assets is equal to the fair value of 100 percent of the joint venture's equity, and (iv) a joint venture provides relevant disclosures. ASU 2023-05 is effective prospectively for all joint venture formations with a formation date on or after January 1, 2025, with early adoption permitted in any interim or annual period in which financial statements have not yet been issued, either prospectively or retrospectively. We are currently evaluating the impact of the adoption of ASU 2023-05 on our consolidated financial statements, but do not believe the adoption of this standard will have a material impact on our consolidated financial statements.

In March 2020, the FASB issued ASU No. 2020-04 Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting and then in January 2021, the FASB issued ASU No. 2021-01. The amendments provide practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance is optional and is effective between March 12, 2020 and December 31, 2024, which was extended from the original sunset date of December 31, 2022 when the FASB issued ASU No. 2022-06 in December 2022. The guidance may be elected over time as reference rate reform activities occur. During the first quarter of 2020, the Company 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. The impact of this guidance did not have a material impact on the Company's consolidated financial statements.

3. Property Acquisitions and Consolidations

Property Acquisitions

During the nine months ended September 30, 2024, we did not acquire any properties from a third party.

(1)In March 2024, the Company entered into an agreement to acquire its partner's 45.0% interest in the joint venture for cash consideration of $7.2 million, which is net of all outstanding debt obligations at contract signing. As a result of the contract terms, it was concluded that the joint venture is a VIE in which the Company is the primary beneficiary, and the investment was consolidated in our financial statements. Upon consolidating the entity, the assets and liabilities of the entity were recorded at fair value which resulted in the recognition of a fair value adjustment of ($55.7 million), which is included in Purchase price and other fair value adjustments in the consolidated statements of operations. Prior to March 2024, the investment was accounted for under the equity method. See Note 16, "Fair Value Measurements."

4. Properties Held for Sale and Property Dispositions

In December 2021, we entered into an amended and restated credit facility, referred to as the 2021 credit facility, that was previously amended by the Company in November 2017, and was originally entered into by the Company in November 2012. As of September 30, 2024, the 2021 credit facility consisted of a $1.25 billion revolving credit facility, a $1.05 billion term loan (or "Term Loan A"), and a $200.0 million term loan (or "Term Loan B") with maturity dates of May 15, 2026, May 15, 2027, and November 21, 2024, respectively. The revolving credit facility has two six-month, as-of-right extension options to May 15, 2027. We also have an option, subject to customary conditions, to increase the capacity of the credit facility to $4.5 billion at any time prior to the maturity dates for the revolving credit facility and term loans without the consent of existing lenders, by obtaining additional commitments from our existing lenders and other financial institutions.

As of September 30, 2024, the 2021 credit facility bore interest at a spread over adjusted Term SOFR plus 10 basis points with an interest period of one or three months, as we may elect, ranging from (i) 72.5 basis points to 140 basis points for loans under the revolving credit facility, (ii) 80 basis points to 160 basis points for loans under Term Loan A, and (iii) 85 basis points to 165 basis points for loans under Term Loan B, in each case based on the credit rating assigned to the senior unsecured long term indebtedness of the Company. In instances where there are either only two ratings available or where there are more than two and the difference between them is one rating category, the applicable rating shall be the highest rating. In instances where there are more than two ratings and the difference between the highest and the lowest is two or more rating categories, then the applicable rating used is the average of the highest two, rounded down if the average is not a recognized category.

As of September 30, 2024, the applicable spread over adjusted Term SOFR plus 10 basis points for the 2021 credit facility was 140 basis points for the revolving credit facility, 160 basis points for Term Loan A, and 165 basis points for Term Loan B. We are required to pay quarterly in arrears a 12.5 to 30 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to the senior unsecured long term indebtedness of the Company. As of September 30, 2024, the facility fee was 30 basis points.

As of September 30, 2024, we had $7.5 million of outstanding letters of credit, $735.0 million drawn under the revolving credit facility and $1.25 billion of outstanding term loans, with total undrawn capacity of $507.5 million under the 2021 credit facility. As of September 30, 2024 and December 31, 2023, the revolving credit facility had a carrying value of $730.9 million and $554.8 million, respectively, net of deferred financing costs. As of September 30, 2024 and December 31, 2023, the term loans had a carrying value of $1.2 billion and $1.2 billion, respectively, net of deferred financing costs.

The Company and the Operating Partnership are borrowers jointly and severally obligated under the 2021 credit facility.

The 2021 credit facility includes certain restrictions and covenants (see Restrictive Covenants below).

Restrictive Covenants

The terms of the 2021 credit facility and our senior unsecured notes include certain restrictions and covenants which may limit, among other things, our ability to pay dividends, make certain types of investments, incur additional indebtedness, incur liens and enter into negative pledge agreements and dispose of assets, and which require compliance with financial ratios relating to the maximum ratio of total indebtedness to total asset value, a minimum ratio of EBITDA to fixed charges, a maximum ratio of secured indebtedness to total asset value and a maximum ratio of unsecured indebtedness to unencumbered asset value. The dividend restriction referred to above provides that we will not, during any time when a default is continuing, make distributions with respect to common stock or other equity interests, except to enable the Company to continue to qualify as a REIT for Federal income tax purposes. As of September 30, 2024 and December 31, 2023, we were in compliance with all such covenants.

Junior Subordinated Deferrable Interest Debentures

In June 2005, the Company and the Operating Partnership issued $100.0 million in unsecured trust preferred securities through a newly formed trust, SL Green Capital Trust I, or the Trust, which is a wholly-owned subsidiary of the Operating Partnership. The securities mature in 2035 and bear interest at a floating rate of 26 basis points over the three-month Term SOFR. Interest payments may be deferred for a period of up to eight consecutive quarters if the Operating Partnership exercises its right to defer such payments. The Trust preferred securities are redeemable at the option of the Operating Partnership, in whole or in part, with no prepayment premium. We do not consolidate the Trust even though it is a variable interest entity as we are not the primary beneficiary. Because the Trust is not consolidated, we have recorded the debt on our consolidated balance sheets and the related payments are classified as interest expense.

Principal Maturities

Combined aggregate principal maturities of mortgages and other loans payable, the 2021 credit facility, trust preferred securities, senior unsecured notes and our share of joint venture debt as of September 30, 2024, including as-of-right extension options but excluding other extension options, were as follows (in thousands):

10. Related Party Transactions

One Vanderbilt Avenue Investment

In December 2016, we entered into agreements with entities owned and controlled by our Chairman, Chief Executive Officer ("CEO") and Interim President, Marc Holliday, and our former President, Andrew Mathias, pursuant to which they agreed to make an investment in our One Vanderbilt project (inclusive of the property and SUMMIT One Vanderbilt) at the appraised fair market value for the interests acquired. This investment entitles these entities to receive a percentage of any profits realized by the Company from its One Vanderbilt project in excess of the Company's capital contributions, of approximately 1.27% and 0.85%, respectively, on account of the property and 1.92% and 1.28%, respectively, on account of SUMMIT One Vanderbilt. The entities had no right to any return of capital. Accordingly, subject to previously disclosed repurchase rights, these interests had no value and these entities were not entitled to any amounts (other than limited distributions to cover tax liabilities incurred) unless and until the Company received distributions from the One Vanderbilt project in excess of the Company's aggregate investment in the project. The entities owned and controlled by Messrs. Holliday and Mathias paid $1.4 million and $1.0 million, respectively, which equaled the fair market value of the interests acquired as of the date the investment agreements were entered into as determined by an independent third party appraisal that we obtained.

Messrs. Holliday and Mathias have the right to tender their interests in the project upon stabilization (50% within three years after stabilization and 100% three years or more after stabilization). In addition, the agreement calls for us to repurchase these interests in the event of a sale of One Vanderbilt or a transactional change of control of the Company. We also have the right to repurchase these interests on the seven-year anniversary of the stabilization of the project or upon the occurrence of certain separation events prior to the stabilization of the project relating to each of Messrs. Holliday’s and Mathias’s continued service with us. The price paid upon a tender of the interests will equal the liquidation value of the interests at the time, with the value being based on the project's sale price, if applicable, or fair market value as determined by an independent third party appraiser. In 2022, stabilization of the property (excluding SUMMIT One Vanderbilt) was achieved. Therefore, Messrs. Holiday and Mathias exercised their rights to tender 50% of their interests in the property (excluding SUMMIT One Vanderbilt) in July 2022. In 2023, stabilization of SUMMIT One Vanderbilt was achieved.

One Vanderbilt Avenue Leases

In November 2018, we entered into a lease agreement with the One Vanderbilt Avenue joint venture covering certain floors at the property. In March 2021, the lease commenced and we relocated our corporate headquarters to the leased space. For the three and nine months ended September 30, 2024, we recorded $0.7 million and $2.2 million, respectively, of rent expense under the lease. For the three and nine months ended September 30, 2023, we recorded $0.7 million and $2.2 million, respectively, of rent expense under the lease.

Additionally, in June 2021, we, through a consolidated subsidiary, entered into a lease agreement with the One Vanderbilt Avenue joint venture for SUMMIT One Vanderbilt, which commenced operations in October 2021. For the three and nine months ended September 30, 2024, we recorded $20.8 million and $33.4 million, respectively, of rent expense under the lease, including percentage rent, of which $14.4 million and $22.7 million, respectively, was recognized as income as a component of Equity in net income (loss) from unconsolidated joint ventures in our consolidated statements of operations. For the three and nine months ended September 30, 2023, we recorded $17.0 million and $31.1 million, respectively, of rent expense under the lease, including percentage rent, of which $11.7 million and $21.0 million, respectively, was recognized as income as a component of Equity in net income (loss) from unconsolidated joint ventures in our consolidated statements of operations.

719 Seventh Avenue

In April 2024, the Company entered into an arrangement to sell the property at 719 Seventh Avenue for $30.5 million to a special purpose entity ("SPE"), of which our former President and current director, Andrew Mathias, is a partner. No amounts from the transaction will be payable to Mr. Mathias. Mr. Mathias is initially expected to own up to 40% of the equity of the SPE representing an investment by Mr. Mathias of up to approximately $7.0 million in the acquisition of the property. The transaction closed during the second quarter of 2024. See Note 4, "Properties Held for Sale and Property Dispositions."

760 Madison Avenue Condominium Unit

In July 2024, the Company entered into an agreement to sell one of the condominium units located at 760 Madison Avenue to an entity owned by a trust of which the beneficiaries are the family members of our Chairman, CEO and Interim President, Marc Holliday, for $8.4 million. The transaction is expected to close in the fourth quarter of 2024.

Earnings per Share

We use the two-class method of computing earnings per share (“EPS”), which is an earnings allocation formula that determines EPS for common stock and any participating securities according to dividends declared (whether paid or unpaid). Under the two-class method, basic EPS is computed by dividing the income available to common stockholders by the weighted-average number of common stock shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur from share equivalent activity.

13. Partners' Capital of the Operating Partnership

The Company is the sole managing general partner of the Operating Partnership and at September 30, 2024 owned 65,235,013 general and limited partnership interests in the Operating Partnership and 9,200,000 Series I Preferred Units. Partnership interests in the Operating Partnership are denominated as “common units of limited partnership interest” (also referred to as “OP Units”) or “preferred units of limited partnership interest” (also referred to as “Preferred Units”). All references to OP Units and Preferred Units outstanding exclude such units held by the Company. A holder of an OP Unit may present such OP Unit to the Operating Partnership for redemption at any time (subject to restrictions agreed upon at the issuance of OP Units to particular holders that may restrict such right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, the Operating Partnership must redeem such OP Unit in exchange for the cash equal to the then value of a share of common stock of the Company, except that the Company may, at its election, in lieu of cash redemption, acquire such OP Unit for one share of common stock. Because the number of shares of common stock outstanding at all times equals the number of OP Units that the Company owns, one share of common stock is generally the economic equivalent of one OP Unit, and the quarterly distribution that may be paid to the holder of an OP Unit equals the quarterly dividend that may be paid to the holder of a share of common stock. Each series of Preferred Units makes a distribution that is set in accordance with an amendment to the partnership agreement of the Operating Partnership. Preferred Units may also be convertible into OP Units at the election of the holder thereof or the Company, subject to the terms of such Preferred Units.

Net income (loss) allocated to the preferred unitholders and common unitholders reflects their pro rata share of net income (loss) and distributions.

14. Share-based Compensation

We have share-based employee and director compensation plans. Our employees are compensated through the Operating Partnership. Under each plan, whenever the Company issues common or preferred stock, the Operating Partnership issues an equivalent number of units of limited partnership interest of a corresponding class to the Company.

The Fifth Amended and Restated 2005 Stock Option and Incentive Plan, or the 2005 Plan, was approved by the Company's Board of Directors in April 2022 and its stockholders in June 2022 at the Company's annual meeting of stockholders. The 2005 Plan authorizes the issuance of stock options, stock appreciation rights, unrestricted and restricted stock, phantom shares, dividend equivalent rights, cash-based awards and other equity-based awards. Subject to adjustments upon certain corporate transactions or events, awards with respect to up to a maximum of 32,210,000 fungible units may be granted under the 2005 Plan. Currently, different types of awards count against the limit on the number of fungible units differently, with (1) full-value awards (i.e., those that deliver the full value of the award upon vesting, such as restricted stock) counting as 2.59 Fungible Units per share subject to such awards, (2) stock options, stock appreciation rights and other awards that do not deliver full value and expire five years from the date of grant counting as 0.84 fungible units per share subject to such awards, and (3) all other awards (e.g., 10-year stock options) counting as 1.0 fungible units per share subject to such awards. Awards granted under the 2005 Plan prior to the approval of the fifth amendment and restatement in June 2022 continue to count against the fungible unit limit based on the ratios that were in effect at the time such awards were granted, which may be different than the current ratios. As a result, depending on the types of awards issued, the 2005 Plan may result in the issuance of more or less than 32,210,000 shares. If a stock option or other award granted under the 2005 Plan expires or terminates, the common stock subject to any portion of the award that expires or terminates without having been exercised or paid, as the case may be, will again become available for the issuance of additional awards. Shares of our common stock distributed under the 2005 Plan may be treasury shares or authorized but unissued shares. Currently, unless the 2005 Plan has been previously terminated by the Company's Board of Directors, new awards may be granted under the 2005 Plan until June 1, 2032, which is the tenth anniversary of the date that the 2005 Plan was most recently approved by the Company's stockholders. As of September 30, 2024, 3.5 million fungible units were available for issuance under the 2005 Plan after reserving for shares underlying outstanding restricted stock units, phantom stock units granted pursuant to our Non-Employee Directors' Deferral Program and LTIP Units.

Stock Options and Class O LTIP Units

Options are granted with an exercise price at the fair market value of the Company's common stock on the date of grant and, subject to employment, generally expire five years or ten years from the date of grant, are not transferable other than on death, and generally vest in one year to five years commencing one year from the date of grant. We have also granted Class O LTIP Units, which are a class of LTIP Units in the Operating Partnership structured to provide economics similar to those of stock options. Class O LTIP Units, once vested, may be converted, at the election of the holder, into a number of common units of the Operating Partnership per Class O LTIP Unit determined by the increase in value of a share of the Company’s common stock at the time of conversion over a participation threshold, which equals the fair market value of a share of the Company’s common stock at the time of grant. Class O LTIP Units are entitled to distributions, subject to vesting, equal per unit to 10% of the per unit distributions paid with respect to the common units of the Operating Partnership.

The fair value of each stock option or LTIP Unit granted is estimated on the date of grant using the Black-Scholes option pricing model based on historical information. There were no options granted during the nine months ended September 30, 2024 or the year ended December 31, 2023.

The remaining weighted average contractual life of the options outstanding was 2.2 years and the remaining average contractual life of the options exercisable was 2.2 years.

During the three and nine months ended September 30, 2024, we recognized no compensation expense related to options. During the three and nine months ended September 30, 2023, we recognized no compensation expense related to options. As of September 30, 2024, there was no unrecognized compensation cost related to unvested stock options.

Restricted Shares

Shares may be granted to certain employees, including our executives, and vesting occurs upon the completion of a service period or our meeting established financial performance criteria. Vesting occurs at rates ranging from 15% to 35% once performance criteria are reached.

A summary of the Company's restricted stock as of September 30, 2024 and December 31, 2023 and changes during the nine months ended September 30, 2024 and the year ended December 31, 2023, are as follows:


	September 30, 2024		December 31, 2023
Balance at beginning of period	4,089,174		3,758,174
Granted	7,734		337,350
Canceled	(10,050)		(6,350)
Balance at end of period	4,086,858		4,089,174
Vested during the period	136,120		147,915
Compensation expense recorded	$	7,935,369	$	7,766,055
Total fair value of restricted stock granted during the period	$	394,851	$	15,789,540

The fair value of restricted stock that vested during the nine months ended September 30, 2024 and the year ended December 31, 2023 was $7.1 million and $10.2 million, respectively. As of September 30, 2024, there was $12.2 million of total unrecognized compensation cost related to restricted stock, which is expected to be recognized over a weighted average period of 2.0 years.

We granted LTIP Units, which include bonus, time-based and performance-based awards, with a fair value of $23.6 million and $38.1 million as of September 30, 2024 and December 31, 2023, respectively. The grant date fair value of the LTIP Unit awards was calculated in accordance with ASC 718. A third-party consultant determined that the fair value of the LTIP Units has a discount to our common stock price. The discount was calculated by considering the inherent uncertainty that the LTIP Units will reach parity with other common partnership units and the illiquidity due to transfer restrictions. As of September 30, 2024, there was $28.5 million of total unrecognized compensation expense related to the time-based and performance-based awards, which is expected to be recognized over a weighted average period of 1.6 years.

During the three and nine months ended September 30, 2024, we recorded compensation expense related to bonus, time-based and performance-based awards of $6.7 million and $19.7 million. During the three and nine months ended September 30, 2023, we recorded compensation expense related to bonus, time-based and performance-based awards of $10.6 million and $31.2 million, respectively.

Deferred Compensation Plan for Directors

Under our Non-Employee Director's Deferral Program, which commenced July 2004, the Company's non-employee directors may elect to defer up to 100% of their annual retainer fee, chairman fees, meeting fees and annual stock grant. Unless otherwise elected by a participant, fees deferred under the program shall be credited in the form of phantom stock units. The program provides that a director's phantom stock units generally will be settled in an equal number of shares of common stock upon the earlier of (i) the January 1 coincident with or the next following such director's termination of service from the Board of Directors or (ii) a change in control by us, as defined by the program. Phantom stock units are credited to each non-employee director quarterly using the closing price of our common stock on the first business day of the respective quarter. Each participating non-employee director is also credited with dividend equivalents or phantom stock units based on the dividend rate for each quarter, which are either paid in cash currently or credited to the director’s account as additional phantom stock units.

During the nine months ended September 30, 2024, 15,945 phantom stock units and 25,590 shares of common stock were issued to our Board of Directors. We recorded compensation expense of $0.2 million and $2.6 million during the three and nine months ended September 30, 2024, respectively, related to the Deferred Compensation Plan. We recorded compensation expense of $0.2 million and $2.5 million during the three and nine months ended September 30, 2023, respectively, related to the Deferred Compensation Plan.

As of September 30, 2024, there were 125,654 phantom stock units outstanding pursuant to our Non-Employee Director's Deferral Program.

Employee Stock Purchase Plan

In 2007, the Company's Board of Directors adopted the 2008 Employee Stock Purchase Plan, or ESPP, to provide equity-based incentives to eligible employees. The ESPP is intended to qualify as an "employee stock purchase plan" under Section 423 of the Code, and has been adopted by the board to enable our eligible employees to purchase the Company's shares of common stock through payroll deductions. The ESPP became effective on January 1, 2008 with a maximum of 500,000 shares of the common stock available for issuance, subject to adjustment upon a merger, reorganization, stock split or other similar corporate change. The Company filed a registration statement on Form S-8 with the SEC with respect to the ESPP. The common stock is offered for purchase through a series of successive offering periods. Each offering period will be three months in duration and will begin on the first day of each calendar quarter, with the first offering period having commenced on January 1, 2008. The ESPP provides for eligible employees to purchase the common stock at a purchase price equal to 85% of the lesser of (1) the market value of the common stock on the first day of the offering period or (2) the market value of the common stock on the last day of the offering period. The ESPP was approved by our stockholders at our 2008 annual meeting of stockholders. As of September 30, 2024, 241,790 shares of our common stock had been issued under the ESPP.

16. Fair Value Measurements

We are required to disclose fair value information with regard to certain of our financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practical to estimate fair value. The FASB guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. We measure and/or disclose the estimated fair value of certain financial assets and liabilities based on a hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. This hierarchy consists of three broad levels: Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date; Level 2 - inputs other than quoted prices included within Level 1, that are observable for the asset or liability, either directly or indirectly; and Level 3 - unobservable inputs for the asset or liability that are used when little or no market data is available. We follow this hierarchy for our assets and liabilities measured at fair value on a recurring and nonrecurring basis. In instances in which the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level of input that is significant to the fair value measurement in its entirety. Our assessment of the significance of the particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

The following tables set forth the assets and liabilities that we measure at fair value on a recurring and non-recurring basis by their levels in the fair value hierarchy as of September 30, 2024 and December 31, 2023 (in thousands):


	September 30, 2024
	Total		Level 1		Level 2		Level 3
Assets:
Marketable securities available-for-sale	$	16,522	$	—	$	16,522	$	—
Interest rate cap and swap agreements (included in Other assets)	17,026		—		17,026		—
Real estate loans held by consolidated securitization vehicles	586,823		—		586,823		—
Liabilities:
Interest rate cap and swap agreements (included in Other liabilities)	$	29,372	$	—	$	29,372	$	—
Senior obligations of consolidated securitization vehicles	571,711		—		571,711		—
Secured borrowing (1)	237,454		—		—		237,454

(1)The Company admitted an additional partner to the One Madison Avenue development project with the partner's indirect ownership in the joint venture totaling 25.0%. The transaction did not meet sale accounting under ASC 860 and, as a result, was treated as a secured borrowing for accounting purposes and is included in Other liabilities in our consolidated balance sheets.


	December 31, 2023
	Total		Level 1		Level 2		Level 3
Assets:
Marketable securities available-for-sale	$	9,591	$	—	$	9,591	$	—
Interest rate cap and swap agreements (included in Other assets)	33,456		—		33,456		—

We evaluate real estate investments and debt and preferred equity investments, including intangibles, for potential impairment primarily utilizing cash flow projections that apply, among other things, estimated revenue and expense growth rates, discount rates and capitalization rates, as well as sales comparison approach, which utilizes comparable sales, listings and sales contracts, all of which are classified as Level 3 inputs.

In March 2024, the Company entered into an agreement to acquire its partner's 45.0% interest in the 10 East 53rd Street joint venture. As a result of the contract terms, it was concluded that the joint venture is a VIE in which the Company is the primary beneficiary, and the investment was consolidated in our financial statements. Upon consolidating the entity, the assets and liabilities of the entity were recorded at fair value which resulted in the recognition of a fair value adjustment of ($55.7 million), which is included in Purchase price and other fair value adjustments in the consolidated statements of operations. This fair value was determined using a third-party valuation which primarily utilized cash flow projections that apply, among other things, estimated revenue and expense growth rates, discount rates and capitalization rates, as well as the sales comparison approach, which utilizes comparable sales, listings, and sales contracts. All of which are classified as Level 3 inputs.

Marketable securities classified as Level 1 are derived from quoted prices in active markets. The valuation technique used to measure the fair value of marketable securities classified as Level 2 were valued based on quoted market prices or model driven valuations using the significant inputs derived from or corroborated by observable market data. We do not intend to sell these securities and it is not more likely than not that we will be required to sell the investments before recovery of their amortized cost bases.

The fair value of derivative instruments is based on current market data received from financial sources that trade such instruments and are based on prevailing market data and derived from third party proprietary models based on well-recognized financial principles and reasonable estimates about relevant future market conditions, which are classified as Level 2 inputs.

The senior obligations of consolidated securitization vehicles represent CMBS that are not owned by the Company. A majority of these securities are either traded in the marketplace or are similar to other securities that are traded in the marketplace. As the valuation of these amounts are based upon quoted prices for similar instruments in active markets, we generally utilize third party pricing service providers to determine the fair value. The Company evaluates and assesses the third party pricing by referring to recent trades of similar securities, ratings, subordination levels, current market data and credit issues. The Company maximizes the use of observable inputs over unobservable inputs and uses the value of the senior obligations of consolidated securitization vehicles as an indicator of the fair value of the real estate loans held by consolidated securitization vehicles. Depending on the significance of the fair value inputs used in determining the fair value, these securities are classified in either Level 2 or Level 3 of the fair value hierarchy. As such, these investments may move between Level 2 and Level 3 of the fair value hierarchy if the significant fair value inputs used to price the CMBS become or cease to be observable.

The fair value of our secured borrowing is determined by projecting future cash flows, which takes into consideration various factors including discount rate and exit capitalization rate, as well as related asset performance and local or macro real estate performance. The inputs used in determining the Company's secured borrowing are considered Level 3.

The financial assets and liabilities that are not measured at fair value on our consolidated balance sheets include cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, debt and preferred equity investments, mortgages and other loans payable and other secured and unsecured debt. The carrying amount of cash and cash equivalents, restricted cash, accounts receivable, and accounts payable and accrued expenses reported in our consolidated balance sheets approximates fair value due to the short-term nature of these instruments. The fair value of debt and preferred equity investments, which is classified as Level 3, is estimated by discounting the future cash flows using current interest rates at which similar loans with the same maturities would be made to borrowers with similar credit ratings. The fair value of borrowings, which is classified as Level 3, is estimated by discounting the contractual cash flows of each debt instrument to their present value using adjusted market interest rates, which is provided by a third-party specialist.

17. Financial Instruments: Derivatives and Hedging

In the normal course of business, we use a variety of commonly used derivative instruments, including, but not limited to, interest rate swaps, caps, collars and floors, to manage interest rate risk. We hedge our exposure to variability in future cash flows for forecasted transactions in addition to anticipated future interest payments on existing debt. We recognize all derivatives on the balance sheet at fair value. Derivatives that are not hedges are adjusted to fair value through earnings. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedge asset, liability, or firm commitment through earnings, or recognized in other comprehensive income (loss) until the hedged item is recognized in earnings. Reported net income and equity may increase or decrease prospectively, depending on future levels of interest rates and other variables affecting the fair values of derivative instruments and hedged items, but will have no effect on cash flows. Currently, all of our designated derivative instruments are effective hedging instruments.

The following table summarizes the notional value at inception and fair value of our consolidated derivative financial instruments as of September 30, 2024 based on Level 2 information. The notional value is an indication of the extent of our involvement in these instruments at that time, but does not represent exposure to credit, interest rate or market risks (dollars in thousands).

During the three and nine months ended September 30, 2024, we recorded a loss of $9.2 million and $2.8 million, respectively, based on the changes in the fair value of forward-starting interest rate swaps, which is included in Purchase price and other fair value adjustments in the consolidated statements of operations. During the three and nine months ended September 30, 2023, we recorded a loss of $0.0 million and $0.2 million, respectively, based on the changes in the fair value of an interest rate cap we sold, which is included in Purchase price and other fair value adjustments in the consolidated statements of operations. During the three and nine months ended September 30, 2024, we recorded a gain of $0.2 million and $0.1 million, respectively, on the changes in fair value, which is included in interest expense in the consolidated statements of operations. During the three and nine months ended September 30, 2023, we recorded a loss of $0.0 million and $0.2 million, respectively, on the changes in fair value, which is included in interest expense in the consolidated statements of operations.

Certain agreements the Company has with each of its derivative counterparties contain a provision where if the Company defaults on any of its indebtedness, then the Company could also be declared in default on its derivative obligations. As of September 30, 2024, the fair value of derivatives in a net liability position, including accrued interest but excluding any adjustment for nonperformance risk related to these agreements, was ($29.7 million). As of September 30, 2024, the Company was not required to post any collateral related to these agreements and was not in breach of any agreement provisions. If the Company had breached any of these provisions, it could have been required to settle its obligations under the agreements at their aggregate termination value of $31.0 million as of September 30, 2024.

Gains and losses on terminated hedges are included in accumulated other comprehensive income, and are recognized into earnings over the term of the related obligation. Over time, the realized and unrealized gains and losses held in accumulated other comprehensive income will be reclassified into earnings as an adjustment to interest expense in the same periods in which the hedged interest payments affect earnings. We estimate that ($11.2 million) of the current balance held in accumulated other comprehensive income will be reclassified into interest expense and $1.3 million of the portion related to our share of joint venture accumulated other comprehensive income will be reclassified into equity in net loss from unconsolidated joint ventures within the next 12 months.

18. Lease Income

The Operating Partnership is the lessor and the sublessor to tenants under operating and sales-type leases. The minimum rental amounts due under the leases are generally subject to scheduled fixed increases or adjustments. The leases generally also require that the tenants reimburse us for increases in certain operating costs and real estate taxes above their base year costs.

20. Segment Information

The Company has three reportable segments, real estate, debt and preferred equity investments, and SUMMIT. In the fourth quarter of 2023, due to quantitative thresholds, SUMMIT was identified as a reportable segment. As such, prior period segment data has been restated to reflect SUMMIT as a reportable segment for comparative purposes.

We evaluate real estate performance and allocate resources based on earnings contributions.

The primary sources of revenue are generated from tenant rents, escalations and reimbursement revenue. Real estate property operating expenses consist primarily of security, maintenance, utility costs, insurance, real estate taxes and, at certain properties, ground rent expense. See Note 5, "Debt and Preferred Equity Investments," for additional details on our debt and preferred equity investments. SUMMIT currently operates one location at One Vanderbilt Avenue in midtown Manhattan with the primary source of revenue generated from ticket sales.

Selected consolidated results of operations for the three and nine months ended September 30, 2024 and 2023, and selected asset information as of September 30, 2024 and December 31, 2023, regarding our operating segments are as follows (in thousands):

December 31, 2023	$	8,707,147	$	464,799	$	359,235	$	9,531,181

We allocate loan loss reserves, net of recoveries, and transaction related costs to the debt and preferred equity segment. We do not allocate marketing, general and administrative expenses to the debt and preferred equity segment because that segment does not have dedicated personnel and the use of personnel and resources is dependent on transaction volume between the three segments, which varies between periods. In addition, we base performance on the individual segments prior to allocating marketing, general and administrative expenses. SUMMIT segment incurs its own marketing, general and administrative expenses for its dedicated personnel, which are included in SUMMIT Operator expenses in the consolidated statement of operations. For the three and nine months ended September 30, 2024, marketing, general and administrative expenses totaled $21.0 million and $62.4 million, respectively. For the three and nine months ended September 30, 2023, marketing, general and administrative expenses totaled $22.9 million and $69.1 million, respectively. All other expenses, except interest and SUMMIT operator expenses, relate entirely to the real estate assets.

There were no transactions between the above three segments other than the SUMMIT lease with our One Vanderbilt Avenue joint venture, which is part of the real estate segment. See Note 10, "Related Party Transactions."

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

SL Green Realty Corp., which is referred to as SL Green or the Company, a Maryland corporation, and SL Green Operating Partnership, L.P., which is referred to as SLGOP or the Operating Partnership, a Delaware limited partnership, were formed in June 1997 for the purpose of combining the commercial real estate business of S.L. Green Properties, Inc. and its affiliated partnerships and entities. The Company is a self-managed real estate investment trust, or REIT, engaged in the ownership, management, operation, acquisition, development, redevelopment, repositioning and financing of commercial real estate properties, principally office properties, located in the New York metropolitan area, principally Manhattan.

As of September 30, 2024, we also managed one office building and one retail building owned by third parties encompassing approximately 0.4 million square feet (unaudited), and held debt and preferred equity investments with a book value excluding the impact of credit losses of $293.9 million, excluding approximately $9.3 million of debt and preferred equity investments and other financing receivables that are included in other balance sheet line items other than the Debt and preferred equity investments line item.

Critical Accounting Policies and Estimates

Rental Revenue

Rental revenues increased due primarily to the consolidation of 10 East 53rd Street ($8.4 million) as a result of the agreement to acquire the partner's interest in the joint venture during the first quarter of 2024, partially offset by a lower contribution from our Same-Store Properties due primarily to increased vacancy at 555 West 57th Street ($2.5 million).

Table of Contents

SUMMIT Operator revenue

SUMMIT Operator revenues were higher for the three months ended September 30, 2024 as compared to the same period in 2023 primarily due to increased attendance.

Investment Income

Investment income decreased due to a lower weighted average debt and preferred equity investment balance for the three months ended September 30, 2024 as compared to the same period in 2023. For the three months ended September 30, 2024, the weighted average debt and preferred equity investment balance outstanding and weighted average yield were $306.2 million and 6.4%, respectively, as compared to $608.7 million and 6.2%, respectively, for the three months ended September 30, 2023.

Interest income from real estate loans held by consolidated securitization vehicles

During the three months ended September 30, 2024, we acquired securities in CMBS securitization trusts that resulted in consolidation of the trusts on our financial statements. The amounts recorded include our interest income as well as the interest income associated with CMBS positions owned by third parties, which is offset by the amounts recorded in Interest expense on senior obligations of consolidated securitization vehicles. As a result, the net impact is limited to the interest income on the CMBS securities we own directly and not the consolidated interest income and interest expense. We did not hold any investments in CMBS securitization trusts that resulted in consolidation during the three months ended September 30, 2023.

Other Income

Other income increased primarily due to higher management, leasing, and construction management fee income ($10.2 million) and increased special servicing fees ($1.2 million) during the three months ended September 30, 2024 as compared to the same period in 2023.

Property Operating Expenses

Property operating expenses decreased due primarily to the termination of the leasehold interest at 625 Madison Avenue upon conversion of the previous mezzanine debt investment in the fee interest at the property to an unconsolidated joint venture in the second quarter of 2023 ($3.8 million), partially offset by increased variable expenses ($1.3 million) and real estate taxes ($1.3 million) at our Same-Store Properties.

SUMMIT Operator expenses

SUMMIT Operator expenses were higher for the three months ended September 30, 2024 as compared to the same period in 2023 due to increased variable expenses, including percentage rent, as a result of increased attendance.

Marketing, General and Administrative Expenses

Marketing, general and administrative expenses decreased to $21.0 million for the three months ended September 30, 2024, as compared to $22.9 million for the same period in 2023 due to lower compensation related expenses.

Interest Expense and Amortization of Deferred Financing Costs, Net of Interest Income

Interest expense and amortization of deferred financing costs, net of interest income, increased primarily due to a decrease in interest capitalization in connection with properties that are under development or redevelopment ($15.4 million), and higher interest expense from the revolving credit facility ($3.0 million) due to an increase in the outstanding balance during the three months ended September 30, 2024 as compared to the three months ended September 30, 2023. These decreases were offset by the repayment of unsecured corporate term loans ($5.8 million) in the third quarter of 2023.

SUMMIT Operator tax benefit (expense)

The decrease in SUMMIT Operator tax expense for the three months ended September 30, 2024 as compared to the same period in 2023 was the result of an adjustment made in the third quarter of 2024 related to 2023 projected tax expense being more than 2023 actual tax expense.

Interest expense on senior obligations of consolidated securitization vehicles

During the three months ended September 30, 2024, we acquired securities in CMBS securitization trusts that resulted in consolidation of the trusts on our financial statements. The amounts include the interest expense associated with CMBS positions owned by third parties, which is an offset to the third party interest income recognized in Interest income from real estate loans held by consolidated securitization vehicles. As a result, the impact is limited to interest income on the CMBS securities we own directly and not the consolidated interest income and interest expense. We did not hold any investments in CMBS securitization trusts that resulted in consolidation during the three months ended September 30, 2023.

Table of Contents

Depreciation and Amortization

Depreciation and amortization increased during the three months ended September 30, 2024 due primarily to the consolidation of 10 East 53rd Street ($3.7 million) as a result of the agreement to acquire the partner's interest in the joint venture during the first quarter of 2024.

Equity in net loss from unconsolidated joint ventures

Equity in net loss from unconsolidated joint ventures increased primarily due to increased vacancy at 280 Park Avenue ($3.2 million) and the disposition of our interest in 717 Fifth Avenue ($2.1 million) during the first quarter of 2024. These increases in loss were partially offset by a decrease in interest expense across our joint venture portfolio ($4.2 million).

Purchase price and other fair value adjustments

During the three months ended September 30, 2024, we recorded a $21.9 million positive fair value adjustment for the secured borrowing related to the previous sale of an interest at One Madison Avenue. This gain was offset by a $9.0 million fair value adjustment related to derivatives that are not designated as hedges for accounting purposes. During the three months ended September 30, 2023, we recorded a $10.2 million purchase price adjustment related to a previous transaction.

Gain on sale of real estate, net

During the three months ended September 30, 2024, we recognized a gain on the sale of Palisades Premier Conference Center ($7.3 million). During the three months ended September 30, 2023, we did not dispose of any properties.

Rental Revenue

Rental revenues decreased due primarily to the deconsolidation of 245 Park Avenue ($77.0 million) as a result of the sale of a joint venture interest during the second quarter of 2023 and a lower contribution from our Same-Store Properties due primarily to increased vacancy at 555 West 57th Street ($8.3 million), 1350 Avenue of the Americas ($4.0 million), and 885 Third Avenue ($2.9 million). These decreases were partially offset by the consolidation of 10 East 53rd Street ($17.0 million) as a result of the agreement to acquire the partner's interest in the joint venture during the first quarter of 2024.

SUMMIT Operator revenue

SUMMIT Operator revenues were higher for the nine months ended September 30, 2024 as compared to the same period in 2023 primarily due to increased attendance.

Table of Contents

Investment Income

Investment income decreased due to a lower weighted average debt and preferred equity investment balance for the nine months ended September 30, 2024 as compared to the same period in 2023. For the nine months ended September 30, 2024, the weighted average debt and preferred equity investment balance outstanding and weighted average yield were $334.6 million and 7.1%, respectively, as compared to $632.3 million and 5.9%, respectively, for the nine months ended September 30, 2023.

Interest income from real estate loans held by consolidated securitization vehicles

During the nine months ended September 30, 2024, we acquired securities in CMBS securitization trusts that resulted in consolidation of the trusts on our financial statements. The amounts recorded include our interest income as well as the interest income associated with CMBS positions owned by third parties, which is offset by the amounts recorded in Interest expense on senior obligations of consolidated securitization vehicles. As a result, the net impact is limited to the interest income on the CMBS securities we own directly and not the consolidated interest income and interest expense. We did not hold any investments in CMBS securitization trusts that resulted in consolidation during the nine months ended September 30, 2023.

Other Income

Other income increased primarily due to fee income related to the sale of 625 Madison Avenue ($11.5 million) as well as higher management, leasing, and construction management fee income ($13.3 million) and an increase in special servicing fees ($1.9 million) during the nine months ended September 30, 2024 as compared to the same period in 2023. These increases were offset by lower lease termination income ($6.4 million) during the nine months ended September 30, 2024 as compared to the same period in 2023, as well as fee income related to the 49.9% interest sale of 245 Park Avenue ($4.7 million) and One Madison Avenue ($2.8 million) during the nine months ended September 30, 2023.

Property Operating Expenses

Property operating expenses decreased due primarily to the deconsolidation of 245 Park in the second quarter of 2023 ($27.2 million) and the termination of the leasehold interest at 625 Madison Avenue upon conversion of the previous mezzanine debt investment in the fee interest at the property to an unconsolidated joint venture in the second quarter of 2023 ($3.8 million). These decreases were partially offset by increased real estate taxes ($2.6 million) at our Same-Store Properties.

SUMMIT Operator expenses

SUMMIT Operator expenses were higher for the nine months ended September 30, 2024 as compared to the same period in 2023 due to increased variable expenses, including percentage rent, as a result of increased attendance.

Marketing, General and Administrative Expenses

Marketing, general and administrative expenses decreased to $62.4 million for the nine months ended September 30, 2024, compared to $69.1 million for the same period in 2023, due to lower compensation related expenses.

Interest Expense and Amortization of Deferred Financing Costs, Net of Interest Income

Interest expense and amortization of deferred financing costs, net of interest income, decreased due to the deconsolidation of 245 Park Avenue in the second quarter of 2023 ($31.1 million), the repayment of unsecured corporate term loans ($12.4 million) in the third quarter of 2023, and the sale of 719 Seventh in the second quarter of 2024 ($3.2 million). These decreases were offset by a decrease in interest capitalization in connection with properties that are under development or redevelopment ($26.9 million) during the nine months ended September 30, 2024 as compared to the same period in 2023, increased interest expense from the revolving credit facility ($10.5 million) due to a higher outstanding balance, and the consolidation of 10 East 53rd Street ($7.2 million) as a result of the agreement to acquire the partner's interest in the joint venture during the first quarter of 2024. The weighted average consolidated debt balance outstanding was $3.8 billion for the nine months ended September 30, 2024, compared to $5.0 billion for the nine months ended September 30, 2023. The consolidated weighted average interest rate was 5.15% for the nine months ended September 30, 2024, as compared to 4.64% for the nine months ended September 30, 2023.

SUMMIT Operator tax benefit (expense)

The increase in SUMMIT Operator tax expense for the nine months ended September 30, 2024 as compared to the same period in 2023 was the result of an adjustment made in the third quarter of 2024 related to 2023 projected tax expense being more than 2023 actual tax expense.

Table of Contents

Interest expense on senior obligations of consolidated securitization vehicles

During the nine months ended September 30, 2024, we acquired securities in CMBS securitization trusts that resulted in consolidation of the trusts on our financial statements. The amounts include the interest expense associated with CMBS positions owned by third parties, which is an offset to the third party interest income recognized in Interest income from real estate loans held by consolidated securitization vehicles. As a result, the impact is limited to interest income on the CMBS securities we own directly and not the consolidated interest income and interest expense. We did not hold any investments in CMBS securitization trusts that resulted in consolidation during the nine months ended September 30, 2023.

Depreciation and Amortization

Depreciation and amortization decreased due primarily to the deconsolidation of 245 Park Avenue in the second quarter of 2023 ($48.5 million), partially offset by the consolidation of 10 East 53rd Street ($7.5 million) as a result of the agreement to acquire the partner's interest in the joint venture during the first quarter of 2024.

Equity in net income (loss) from unconsolidated joint ventures

Equity in net income (loss) from unconsolidated joint ventures increased due primarily to increased income at 2 Herald Square ($128.3 million) as a result of the $141.7 million gain on discounted debt extinguishment at the property during the nine months ended September 30, 2024. In addition, a $30.7 million gain on discounted debt extinguishment was recognized at 280 Park Avenue during the nine months ended September 30, 2024. The nine months ended September 30, 2023 included $23.6 million of income recognized for holdover rent, interest and reimbursement of attorneys' fees collected following the completion of legal proceedings against a former tenant and its guarantor.

Equity in net gain (loss) on sale of interest in unconsolidated joint venture/real estate

During the nine months ended September 30, 2024, we recognized a gain on the sale of our interest in 717 Fifth Avenue ($24.9 million) and a loss on the sale of our interest in 625 Madison Avenue ($7.3 million). During the nine months ended September 30, 2023, we recognized a loss on the sale of our interest in 121 Greene Street ($0.3 million).

Purchase price and other fair value adjustments

During the nine months ended September 30, 2024, we recorded a $55.7 million negative fair value adjustment relating to the consolidation of 10 East 53rd Street and a $2.6 million negative fair value adjustment related to derivatives that are not designated as hedges for accounting purposes, partially offset by a $21.9 million positive fair value adjustment for the secured borrowing related to the previous sale of an interest at One Madison Avenue. During the nine months ended September 30, 2023, we recorded a $17.0 million fair value adjustment relating to the 50.1% interest we retained in 245 Park Avenue, which was deconsolidated when a 49.9% joint venture interest was sold. This was partially offset by a $10.2 million purchase price adjustment related to a previous transaction.

Gain (loss) on sale of real estate, net

During the nine months ended September 30, 2024, we recognized a gain on the sale of Palisades Premier Conference Center ($7.3 million) and a loss on the sale of 719 Seventh Avenue ($2.1 million). During the nine months ended September 30, 2023, we recognized a loss on the sale of a 49.9% joint venture interest in 245 Park Avenue ($28.3 million).

Depreciable real estate reserves and impairment

During the nine months ended September 30, 2024, we recognized depreciable real estate reserves and impairments at 719 Seventh Avenue ($46.3 million) and 760 Madison Avenue ($13.7 million), reflective of $13.2 million of capitalized interest for 760 Madison Avenue, to reduce the carrying value of our investments based on the sales contracts that the Company entered into for these properties. In addition, we recognized depreciable real estate reserves and impairments related to our investment in 625 Madison Avenue ($5.9 million), which remained under contract for sale as of March 31, 2024 prior to the sale closing in the second quarter of 2024. During the nine months ended September 30, 2023, we recognized depreciable real estate reserves and impairments related to 625 Madison Avenue ($305.9 million) following a strategic review of the property that addressed a range of relevant considerations, including the increase in ground rent to an amount substantially above what the Company believed was appropriate.

Gain on early extinguishment of debt

During the nine months ended September 30, 2024, we recognized a $17.8 million gain on discounted debt extinguishment at 719 Seventh Avenue.

Table of Contents

Loan loss and other investment reserves, net of recoveries

During the nine months ended September 30, 2024, we did not recognize any loan loss and other investment reserves. During the nine months ended September 30, 2023, we recorded a $6.9 million loan loss reserve on one debt and preferred equity investment.

Liquidity and Capital Resources

We currently expect that the principal sources of funds to meet our short-term and long-term liquidity requirements for working capital, acquisitions, development or redevelopment of properties, tenant improvements, leasing costs, share repurchase, dividends to shareholders, distributions to unitholders, repurchases or repayments of outstanding indebtedness, and for debt and preferred equity investments will include:

(1)Cash flow from operations;

(2)Cash on hand;

(3)Net proceeds from divestitures of properties and redemptions, participations, dispositions and repayments of debt and preferred equity investments;

(4)Borrowings under the revolving credit facility;

(5)Other forms of secured or unsecured financing; and

(6)Proceeds from common or preferred equity or debt offerings by the Company or the Operating Partnership (including issuances of units of limited partnership interest in the Operating Partnership and Trust preferred securities).

Cash flow from operations is primarily dependent upon the collectability of rent, the occupancy level of our portfolio, the net effective rental rates achieved on our leases, the collectability of rent, operating escalations and recoveries from our tenants and the level of operating and other costs. Additionally, we believe that our debt and preferred equity investment program will continue to serve as a source of operating cash flow.

The combined aggregate principal maturities of mortgages and other loans payable, the 2021 credit facility, senior unsecured notes (net of discount), trust preferred securities, our share of joint venture debt, including as-of-right extension options, estimated interest expense, and our obligations under our financing and operating leases, as of September 30, 2024 are as follows (in thousands):

We estimate that for the remainder of the year ending December 31, 2024, we expect to incur $15.1 million of leasing capital expenditures and $12.1 million of recurring capital expenditures on existing consolidated properties. In addition, we expect to incur $26.1 million of development or redevelopment expenditures on existing consolidated properties, none of which will be funded by construction financing facilities or loan reserves. We expect our share of capital expenditures at our joint venture properties will be $68.5 million, of which $57.2 million will be funded by construction financing facilities or loan reserves. We expect to fund capital expenditures from operating cash flow, existing liquidity, and borrowings from construction financing facilities. Future property acquisitions may require substantial capital investments for refurbishment and leasing costs.

Table of Contents

As of September 30, 2024, we had liquidity of $0.7 billion, comprised of $507.5 million of availability under our revolving credit facility and $204.7 million of consolidated cash on hand, inclusive of $16.5 million of marketable securities. This liquidity excludes $156.1 million representing our share of cash at unconsolidated joint venture properties. We may seek to divest of properties, interests in properties or debt and preferred equity investments or access private and public debt and equity capital when the opportunity presents itself, although there is no guarantee that this capital will be made available to us at efficient levels or at all. Management believes that these sources of liquidity, if we are able to access them, along with potential refinancing opportunities for secured and unsecured debt, will allow us to satisfy our debt and other obligations, as described above, upon maturity, if not before.

We have investments in several real estate joint ventures with various partners who are generally considered to be financially stable. Most of our joint ventures are financed with non-recourse debt. We believe that property level cash flows along with unfunded committed indebtedness and proceeds from the refinancing of outstanding secured indebtedness will be sufficient to fund the capital needs of our joint venture properties.

Cash Flows

The following summary discussion of our cash flows is based on our consolidated statements of cash flows in "Item 1. Financial Statements" and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below.

Cash, restricted cash, and cash equivalents were $315.1 million and $309.3 million as of September 30, 2024 and 2023, respectively, representing a decrease of $5.8 million. The decrease was a result of the following changes in cash flows (in thousands):


	Nine Months Ended September 30,
	2024		2023		(Decrease) Increase
Net cash provided by operating activities	$	71,420	$	181,338	$	(109,918)
Net cash (used in) provided by investing activities	(37,475)		271,684		(309,159)
Net cash used in financing activities	(54,339)		(527,753)		473,414

Our principal sources of operating cash flow are the properties in our consolidated and joint venture portfolios, third-party fees and our debt and preferred equity portfolio. These sources generate a relatively consistent stream of cash flow that provides us with resources to pay operating expenses, debt service and fund dividend and distribution requirements.

Cash is used in investing activities to fund acquisitions, development or redevelopment projects and recurring and nonrecurring capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing and property management skills and invest in existing buildings that meet our investment criteria. During the nine months ended September 30, 2024, when compared to the nine months ended September 30, 2023, we used cash primarily for the following investing activities (in thousands):



Capital expenditures and capitalized interest	$	31,344
Acquisition deposits and deferred purchase price	(12,817)
Joint venture investments	(252,426)
Distributions from joint ventures	(9,577)
Proceeds from sales of real estate/partial interest in property	(69,454)


Debt and preferred equity and other investments	3,771
Increase in net cash (used in) provided by investing activities	$	(309,159)

Funds spent on capital expenditures, which are comprised of building and tenant improvements, decreased from $194.0 million for the nine months ended September 30, 2023 to $162.7 million for the nine months ended September 30, 2024 due to decreased spending on development and redevelopment properties.

We generally fund our investment activity through the sale of real estate, the sale or repayment of debt and preferred equity investments, property-level financing, our corporate credit facilities, or construction facilities. From time to time, the Company may issue common or preferred stock or equity-linked securities, or the Operating Partnership may issue common or preferred units of limited partnership interest.

The variable rate debt shown above generally bears interest at an interest rate based on adjusted Term SOFR (4.85% and 5.35% as of September 30, 2024 and December 31, 2023, respectively). Our consolidated debt as of September 30, 2024 had a weighted average term to maturity of 1.88 years.

Certain of our debt and equity investments and other investments, with carrying values of $109.5 million as of September 30, 2024 and $168.7 million as of December 31, 2023, are variable rate investments which mitigate our exposure to interest rate changes on our unhedged variable rate debt. Inclusive of the mitigating effect of these investments, the net ratio of our consolidated variable rate debt to total debt was 11.7% and 3.0% as of September 30, 2024 and December 31, 2023, respectively.

2021 Credit Facility

Table of Contents

there are more than two ratings and the difference between the highest and the lowest is two or more rating categories, then the applicable rating used is the average of the highest two, rounded down if the average is not a recognized category.

The Company and the Operating Partnership are borrowers jointly and severally obligated under the 2021 credit facility.

The 2021 credit facility includes certain restrictions and covenants (see Restrictive Covenants below).

Restrictive Covenants

Interest Rate Risk

We are exposed to changes in interest rates primarily from our variable rate debt. Our exposure to interest rate fluctuations are managed through the use of interest rate derivative instruments and through our variable rate debt and preferred equity investments. As of September 30, 2024, $3.3 billion of our consolidated long-term debt and $6.1 billion of our share of joint venture long-term debt bears interest at fixed rates. Our variable rate debt and variable rate joint venture debt as of September 30, 2024 bore interest based on a spread to LIBOR of 145 basis points and Term SOFR of 50 basis points to 677 basis points. Based on the debt outstanding as of September 30, 2024, a hypothetical 100 basis point increase in the applicable floating interest rate curve would increase our consolidated annual interest cost, net of interest income from variable rate debt and preferred equity investments, by $4.1 million and would increase our share of joint venture annual interest cost by $15.1 million. As of September 30, 2024, $0.1 billion of our debt and preferred equity portfolio was indexed to SOFR.

We recognize most derivatives on the balance sheet at fair value. Derivatives that are not hedges for accounting purposes are adjusted to fair value through income. If a derivative is considered a hedge for accounting purposes, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedged asset, liability, or firm commitment through earnings, or recognized in other comprehensive income (loss) until the hedged item is recognized in earnings.

Off-Balance Sheet Arrangements

We have off-balance sheet investments, including joint ventures and debt and preferred equity investments. These investments all have varying ownership structures. A majority of our joint venture arrangements are accounted for under the equity method of accounting as we have the ability to exercise significant influence, but not control, over the operating and financial decisions of these joint venture arrangements. Our off-balance sheet arrangements are discussed in Note 5, "Debt and Preferred Equity Investments" and Note 6, "Investments in Unconsolidated Joint Ventures" in the accompanying consolidated financial statements.

Dividends/Distributions

We expect to pay dividends to our stockholders based on the distributions we receive from our Operating Partnership.

To maintain our qualification as a REIT, we must pay annual dividends to our stockholders of at least 90% of our REIT taxable income, determined before taking into consideration the dividends paid deduction and net capital gains.

Table of Contents

Any dividend we pay may be in the form of cash, stock or a combination thereof, subject to IRS limitations on the use of stock for dividends. Additionally, if our REIT taxable income in a particular year exceeds the amount of cash dividends we pay in that year, we may pay stock dividends in order to maintain our REIT status and avoid certain REIT-level taxes.

Before we pay any cash dividend, whether for Federal income tax purposes or otherwise, which would only be paid out of available cash to the extent permitted under the 2021 credit facility and senior unsecured notes, we must first meet both our operating requirements and scheduled debt service on our mortgages and loans payable.

Insurance

We maintain “all-risk” property and rental value coverage (including coverage regarding the perils of flood, earthquake and terrorism, excluding nuclear, biological, chemical, and radiological terrorism ("NBCR")), within two property insurance programs and liability insurance. Separate property and liability coverage may be purchased on a stand-alone basis for certain assets, such as development projects. Additionally, one of our captive insurance companies, Belmont Insurance Company, or Belmont, provides coverage for NBCR terrorist acts above a specified trigger. Belmont's retention is reinsured by our other captive insurance company, Ticonderoga Insurance Company ("Ticonderoga"). If Belmont or Ticonderoga are required to pay a claim under our insurance policies, we would ultimately record the loss to the extent of required payments. However, there is no assurance that in the future we will be able to procure coverage at a reasonable cost. Further, if we experience losses that are uninsured or that exceed policy limits, we could lose the capital invested in the damaged properties as well as the anticipated future cash flows from those properties. Additionally, our debt instruments contain customary covenants requiring us to maintain insurance and we could default under our debt instruments if the cost and/or availability of certain types of insurance make it impractical or impossible to comply with such covenants relating to insurance. Belmont and Ticonderoga provide coverage solely on properties owned by the Company or its affiliates.

Furthermore, with respect to certain of our properties, including properties held by joint ventures or subject to triple net leases, insurance coverage is obtained by a third-party and we do not control the coverage. While we may have agreements with such third parties to maintain adequate coverage and we monitor these policies, such coverage ultimately may not be maintained or adequately cover our risk of loss.

Funds from Operations

FFO is a widely recognized non-GAAP financial measure of REIT performance. The Company computes FFO in accordance with standards established by NAREIT, which may not be comparable to FFO reported by other REITs that do not compute FFO in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than the Company does. The revised White Paper on FFO approved by the Board of Governors of NAREIT in April 2002, and subsequently amended in December 2018, defines FFO as net income (loss) (computed in accordance with GAAP), excluding gains (or losses) from sales of properties and real estate related impairment charges, plus real estate related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures.

The Company presents FFO because it considers it an important supplemental measure of the Company’s operating performance and believes that it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, particularly those that own and operate commercial office properties. The Company also uses FFO as one of several criteria to determine performance-based compensation for members of its senior management. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions, and real estate related impairment charges, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, and interest costs, providing perspective not immediately apparent from net income. FFO does not represent cash generated from operating activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance or to cash flow from operating activities (determined in accordance with GAAP) as a measure of the Company’s liquidity, nor is it indicative of funds available to fund the Company’s cash needs, including our ability to make cash distributions.

Seasonality

Our business at SUMMIT is subject to tourism trends and weather conditions, resulting in some seasonal fluctuation. In 2023 and 2022, approximately 14.0% to 16.0% of our annual SUMMIT revenue was realized in the first quarter, 24.0% to 26.0% was realized in the second quarter, 28.0% to 30.0% was realized in the third quarter, and 29.0% to 31.0% was realized in the fourth quarter. We do not consider any other components of our business to be subject to material seasonal fluctuations.

ITEM 4. CONTROLS AND PROCEDURES

SL GREEN REALTY CORP.

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based closely on the definition of "disclosure controls and procedures" in Rule 13a-15(e) of the Exchange Act. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Company to disclose material information otherwise required to be set forth in our periodic reports. Also, the Company has investments in certain unconsolidated entities. As the Company does not control these entities, its disclosure controls and procedures with respect to such entities are necessarily substantially more limited than those the Company maintains with respect to its consolidated subsidiaries.

As of the end of the period covered by this report, the Company carried out an evaluation, under the supervision and with the participation of the Company's management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based upon that evaluation as of the end of the period covered by this report, the Company's Chief Executive Officer and Chief Financial Officer concluded that its disclosure controls and procedures were effective to give reasonable assurances to the timely collection, evaluation and disclosure of information relating to the Company that would potentially be subject to disclosure under the Exchange Act and the rules and regulations promulgated thereunder.

Changes in Internal Control over Financial Reporting

There have been no significant changes in the Company's internal control over financial reporting during the quarter ended September 30, 2024 that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.
