EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended ~~September 30, 2017~~March 31, 2021 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;~~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, 2017~~March 31, 2021 the Company owns ~~95.55%~~94.35% of the outstanding general and limited partnership interest in the Operating ~~Partnership. The Company also~~Partnership and owns 9,200,000 Series I Preferred Units of the Operating Partnership. As of ~~September 30, 2017,~~March 31, 2021, noncontrolling investors held, in aggregate, a ~~4.45%~~5.65% 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;

•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;~~


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

◦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.~~amended, or the Exchange Act.

owned as of the Record Date, approximately $0.3735 in cash and 0.0279 shares of common stock. Shareholders who elected to receive shares received, for each share of common stock they owned as of the Record Date, approximately 0.0343 shares of common stock. The number of shares issued was calculated based on the volume weighted average trading price of SLG's common stock between January 5-7, 2021, of $58.15 per share.

To mitigate the dilutive impact of the common stock issued in the special dividend, the board of directors also authorized a reverse stock split, which was effective after markets closed on January 20, 2021. On January 8, 2021, a committee of the Board of Directors calculated the ratio for the reverse stock split of our issued and outstanding shares of common stock as 1.02918-for-1. After the issuance of the dividend and the completion of the reverse stock split, the number of shares of our common stock outstanding was equivalent to the number of total shares outstanding on the Record Date (not including any issuances or repurchases that occurred following the Record Date, as well as any fractional shares that would have been issued but for which cash-in-lieu was paid). However, on a relative basis, some individual shareholders may have more shares of SLG’s common stock, and some individual shareholders may have fewer shares of our common stock, depending on their individual elections to receive cash or stock and as a result of the cash option being oversubscribed.

All share-related references and measurements including the number of shares outstanding, share prices, number of shares repurchased, earnings per share, dividends per share, and share-based compensation awards, have been retroactively adjusted to reflect the reverse stock split for all periods presented in this Quarterly Report on Form 10-Q.

Notes to Consolidated Financial Statements

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 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 which is 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, 2017,~~March 31, 2021, noncontrolling investors held, in the aggregate, a ~~4.45%~~5.65% 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".~~Statements."

~~Reckson Associates Realty Corp., or Reckson,~~On December 4, 2020 our Board of Directors declared an ordinary dividend and ~~Reckson Operating Partnership, L.P., or ROP, are wholly-owned subsidiaries~~a special dividend (together, "the Total Dividend"). The Total Dividend was paid on January 15, 2021 to shareholders of ~~SL Green Realty Corp.~~

Asrecord at the close of ~~September 30, 2017, we owned~~ business on December 15, 2020 ("the ~~following interests in properties~~Record Date"). Shareholders had the opportunity to elect to receive the Total Dividend in the ~~New York Metropolitan area, primarily~~form of all cash or all stock, subject to proration if either option was oversubscribed. As a result of the elections made, the cash option was oversubscribed and was prorated. Shareholders who elected to receive cash received, for each share of common stock they owned as of the Record Date, approximately $0.3735 in ~~midtown Manhattan. Our investments~~cash and 0.0279 shares of common stock. Shareholders who elected to receive shares received, for each share of common stock they owned as of the Record Date, approximately 0.0343 shares of common stock. The number of shares issued was calculated based on the volume weighted average trading price of SLG's common stock between January 5-7, 2021, of $58.15 per share.

To mitigate the dilutive impact of the common stock issued in the ~~New York Metropolitan area~~special dividend, the board of directors also ~~include investments~~authorized a reverse stock split, which was effective after markets closed on January 20, 2021. On January 8, 2021, a committee of the Board of Directors calculated the ratio for the reverse stock split of our issued and outstanding shares of common stock as 1.02918-for-1. After the issuance of the dividend and the completion of the reverse stock split, the number of shares of our common stock outstanding was equivalent to the number of total shares outstanding on the Record Date (not including any issuances or repurchases that occurred following the Record Date, as well as any fractional shares that would have been issued but for which cash-in-lieu was paid). However, on a relative basis, some individual shareholders may have more shares of SLG’s common stock, and some individual shareholders may have fewer shares of our common stock, depending on their individual elections to receive cash or stock and as a result of the cash option being oversubscribed.

Subsequent Events

In April 2021, the Company exercised its option to acquire the fee interest in 461 Fifth Avenue from the ground lessor of the property for a purchase price of $28.0 million. At March 31, 2021, the Company held the leasehold interest in the property. The transaction is expected to close in the second quarter of 2021.

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 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." All significant intercompany balances and transactions have been eliminated.

We consolidate a ~~variable interest entity, or~~ 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.

Investment in Commercial Real Estate Properties

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted) 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 calculated fair value of the property. We also evaluate our real estate properties for potential impairment when a real estate property has been classified as held for sale. Real estate assets held for sale are valued at the lower of either their carrying value or fair value less costs to sell. We do not believe that there were any indicators of impairment at any of our consolidated properties at September 30, 2017. We recorded no depreciable real estate reserves for the three months ended September 30, 2017, and

~~Table of Contents~~

~~SL Green Realty Corp. and SL Green Operating Partnership, L.P.~~

~~Notes to Consolidated Financial Statements (cont.)~~

~~September 30, 2017~~

~~(unaudited)~~

~~aggregate depreciable real estate reserves of $85.3 million for the nine months ended September 30, 2017. See Note 4, "Property Dispositions".~~

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 ~~three~~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 ~~one~~1 year to 1415 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 ~~one~~1 year to 1415 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. The tenant improvements and origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). We assess fair value of the leases based on estimated cash flow projections that utilize appropriate discount ~~and capitalization~~ 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 exceeds substantially all of the fair value of the 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. On the consolidated balance sheets, financing leases include the amounts previously captioned "Properties under capital lease." 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 periodic basis, we assess whether there are any indications that the value of our real estate properties may be impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted) 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 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.

For the three months ended March 31, 2021, we recognized ~~$4.6 million and $15.8 million~~($1.9 million) of rental revenue for the ~~three and nine months ended September 30, 2017, and $0.2 million and $191.4 million of rental revenue for the three and nine months ended September 30, 2016 for the~~ amortization of aggregate ~~below-market~~above-market leases in excess of ~~above-market~~below-market leases ~~and a reduction in lease origination costs,~~ resulting from the allocation of the purchase price of the applicable properties. ~~Included in~~For the three months ended March 31, 2020 , we recognized $1.2 million of rental revenue ~~is zero and $172.4 million for the three and nine months ended September 30, 2016,~~ for the amortization of ~~the~~aggregate below-market lease at 388-390 Greenwich Street as a result of the tenant exercising their option to purchase the property and entering into an agreement to accelerate the sale. For the three and nine months ended September 30, 2017, we recognized as a reduction to interest expense the amortizationleases in excess of above-market rate mortgages of $0.0 million and $0.8 million, respectively. For the three and nine months ended September 30, 2016, we recognized as a reduction to interest expense the amortization of the above-market rate mortgages assumed of $0.7 million and $2.0 million, respectively.leases.

~~As of September 30, 2017 and December 31, 2016,~~ ~~$3.9 million~~ and none, respectively and $1.1 million and none, respectively, of net intangible assets and net intangible liabilities, were reclassified to assets held for sale and liabilities related to assets held for sale.

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 security as held-to-maturity, available-for-sale, or trading. As of ~~September 30, 2017,~~March 31, 2021, we did not have any securities designated as held-to-maturity or trading. We account for our available-for-sale securities at fair value pursuant to ~~Accounting Standards Codification, or~~ ASC 820-10, with the net unrealized gains or losses reported as a component of accumulated other comprehensive income or loss. ~~Any unrealized~~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.

~~The cost of bonds and marketable securities sold is determined using the specific identification method.~~

At ~~September 30, 2017~~ ~~and December 31, 2016, we held the following marketable securities (in thousands):~~

$ 48,315
Commercial mortgage-backed securities 28,802
36,795
Total marketable securities available-for-sale $ 28,802
$ 85,110

The cost basis of the commercial mortgage-backed securities was $23.0 million and $27.5 million ~~and $36.0 million~~ at ~~September 30, 2017~~March 31, 2021 and December 31, ~~2016,~~2020, respectively. These securities mature at various times through ~~2049.~~ 2035. All securities were in an unrealized gain position at March 31, 2021 and December 31, 2020 except for 1 security, which had an unrealized loss of $0.7 million and a fair market value of $7.1 million at March 31, 2021, and an unrealized loss of $0.7 million and a fair value of $7.0 million at December 31, 2020. This marketable security had been in a continuous unrealized loss position for more than 12 months at March 31, 2021 and less than 12 months at December 31, 2020. 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.

We held no0 equity marketable securities as of ~~September 30, 2017. The cost basis of the equity marketable securities was $43.3 million at~~March 31, 2021 and December 31, ~~2016.~~2020.

During the three ~~and nine~~ months ended ~~September 30, 2017,~~March 31, 2021, we ~~disposed of marketable securities for~~received aggregate net proceeds of ~~$0.8~~$5.0 million ~~and $55.2 million, respectively.~~from the repayment of 1 marketable security.

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 ~~the~~each joint ventures' actual and projected ~~discounted~~ cash flows. We do not believe that the values of any of our equity investments were impaired at ~~September 30, 2017.~~March 31, 2021.

~~Reserve~~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 ~~Possible Credit Losses~~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 are the owner of tenant improvements for accounting purposes or if the tenant is. 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.

When management concludes that we are the owner of tenant improvements for accounting purposes, we record amounts funded to construct the tenant improvements as a capital asset. For these tenant improvements, we record amounts reimbursed by tenants as a reduction of the capital asset. When management concludes that the tenant is the owner of tenant improvements for accounting purposes, we record our contribution towards those improvements as a lease incentive, which is included in deferred costs, net on our consolidated balance sheets and amortized as a reduction to rental revenue on a straight-line basis over the term of the lease.

The ~~expense~~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 ~~possible credit losses~~the building over a base year. In some leases, in ~~connection~~lieu of paying additional rent based upon increases in certain building operating expenses, the tenant will pay additional rent based upon increases in the

(unaudited)

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.

We recognize lease concessions related to COVID-19, such as rent deferrals and abatements, in accordance with the Lease Modification Q&A issued by the FASB in April 2020, which provides entities with the option to elect to account for lease concessions as though the enforceable rights and obligations existed in the original lease. This election is only available when total cash flows resulting from the modified lease are substantially similar to the cash flows in the original lease. When total cash flows resulting from the modified lease are not substantially similar to the cash flows in the original lease, we account for the concession agreement as a new lease.

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.

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 ~~increase~~adjust the allowance for ~~possible credit~~loan losses to the ~~level that~~appropriate level. Amounts are written off from the allowance when we ~~estimate~~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 ~~adequate,~~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 ~~considering delinquencies, loss experience and collateral quality. Other factors considered include geographic trends, product diversification,~~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 ~~size of the portfolio and current economic conditions. Based upon these factors, we establish a provision for possible credit loss on each individual investment. When it is probable that we~~investment will be ~~unable~~reclassified at its expected amount to ~~collect all amounts contractually due,~~be collected.

Other financing receivables that are included in balance sheet line items other than the ~~investment is considered impaired.~~

~~Where impairment is indicated on an investment that is held to maturity, a valuation allowance is~~Debt and Preferred Equity Investments line are also measured ~~based upon the excess of the recorded investment amount over~~at the net ~~fair value of~~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 ~~collateral. Any deficiency between~~net amount expected to be collected within Other assets in the ~~carrying amount of~~consolidated balance sheets. Accrued interest receivables that are written off are recognized as an ~~asset~~expense in loan loss and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of ourother investment ~~we will adjust our reserves accordingly. There were no loan reserves recorded during the three and nine months ended September 30, 2017 and 2016.~~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 ~~SL Green's~~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 ~~SL Green's~~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.

~~Pursuant to amendments to the Code that became effective January 1, 2001, we~~We have elected, and may elect in the future, to treat certain of our ~~existing or newly created~~ 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

During the three ~~and nine~~ months ended ~~September 30, 2017,~~March 31, 2021, we recorded a Federal, state and local tax ~~provisions~~provision of ~~$0.1 million~~$0.7 million. During the three months ended March 31, 2020, we recorded a Federal, state and ~~$2.8 million, respectively.~~local provision of $1.1 million.

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 ~~evaluations~~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 ~~primarily~~ located in ~~Manhattan. We also have properties located in Brooklyn, Long Island, Westchester County, Connecticut and~~the New ~~Jersey.~~York metropolitan area. The tenants located in our buildings operate in various industries. Other than ~~two tenants, Credit Suisse Securities (USA), Inc. and~~1 tenant, Viacom ~~International,~~CBS Inc., ~~who account~~which accounts for ~~8.8% and 6.7%~~5.9% of our share of annualized cash rent, 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 rent, at ~~September 30, 2017.~~ March 31, 2021.

For the three months ended ~~September 30, 2017, 8.9%, 6.3%, 6.2%, and 5.4%~~March 31, 2021, the following properties contributed more than 5.0% of our ~~share of~~annualized cash rent from office properties, including our ~~share of joint venture annualized rent, was attributable to 1515 Broadway, 11 Madison Avenue, 1185 Avenue of the Americas, and 420 Lexington Avenue, respectively.

The guidance clarifies the changes to the terms or conditions of a share-based payment award that require an entity to apply modification accounting in Topic 718. The guidance is effective for fiscal years beginning after December 15, 2017 and early adoption is permitted. The Company has not yet adopted the guidance.

In February 2017, the FASB issued Accounting Standards Update (ASU) No. 2017-05 to clarify the scope of Subtopic 610-20 as well as provide guidance on accounting for partial sales of nonfinancial assets. Subtopic 610-20 was issued in May 2014 as part of ASU 2014-09. The Company anticipates adopting this guidance January 1, 2018, and applying the modified retrospective approach.

all of the fair value of the gross assets is concentrated in a single identifiable asset or group of assets. The Company adopted the guidance on the issuance date effective January 5, 2017. The Company expects that most of our real estate acquisitions will be considered asset acquisitions under the new guidance and that transaction costs will be capitalized to the investment basis which is then subject to a purchase price allocation based on relative fair value.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. The guidance will require entities to show the changes on the total cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between these items on the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company has not yet adopted this new guidance and is currently evaluating the impact of adopting this new accounting standard on the Company’s consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The ASU provides final guidance on eight cash flow issues, including debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, distributions received from equity method investees, separately identifiable cash flows and application of the predominance principle, and others. The amendments in the ASU are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted the guidance effective January 1, 2017 and there was nomaterial impact on ~~the Company’s consolidated financial statements.~~

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The guidance changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the current ‘incurred loss’ model with an ‘expected loss’ approach. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted after December 2018. The Company has not yet adopted this new guidance and is currently evaluating the impact of adopting this new accounting standard on the Company’sour consolidated financial statements.

In March ~~2016,~~2020, the FASB issued ASU No. ~~2016-09, Compensation - Stock Compensation~~2020-04 Reference Rate Reform (Topic ~~718): Improvements to Employee Share-Based Payment Accounting.

~~In March 2016,~~2021, the FASB issued ASU 2016-07, Investments Equity Method and Joint Ventures (Topic 323). The guidance eliminates the requirement that an entity retroactively adopt the equity method of accounting if an investment qualifies for use of the equity method as a result of an increase in the level of ownership or degree of influence.No. 2021-01. The amendments ~~require~~provide practical expedients for reference rate reform related activities that ~~the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest~~impact debt, leases, derivatives and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. The Company adopted the guidance effective January 1, 2017 and there was no impact on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases. The guidance requires lessees to recognize lease assets and lease liabilities for those leases classified as operating leases under the previous standard. Depending on the lease classification, lessees will recognize expense based on the effective interest method for finance leases or on a straight-line basis for operating leases. The accounting applied by a lessor is largely unchanged from that applied under the previous standard. One of the impacts on the Company will be the presentation and disclosure in the financial statements of non-lease components such as charges to tenants for a building’s operating expenses. The non-lease components will be presented separately from the lease components in both the Consolidated Statements of Operations and Consolidated Balance Sheets. Another impact is the measurement and presentation of ground leases under which the Company is lessee. The Company is required to record a liability for the obligation to make payments under the lease and an asset for the right to use the underlying asset during the lease term and will also apply the new expense recognition requirements given the lease classification. The Company is currently quantifying these impacts.other contracts. The guidance is optional and is effective between March 12, 2020 and December 31, 2022. The guidance may be elected over time as reference rate reform activities occur.

measured under the fair value option in other comprehensive income. The guidance is effective for fiscal years beginning after December 15, 2017, and for interim periods therein. The Company has not yet adopted this new guidance and is currently evaluating the impact of adopting this new accounting standard on the Company’s consolidated financial statements.

In May 2014, the FASB issued a new comprehensive revenue recognition guidance which requires us to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods and services (ASU 2014-09). The FASB also issued implementation guidance in March 2016, April 2016 and May 2016 - ASU’s 2016-08, 2016-10 and 2016-12, respectively.

These ASUs are effective for annual and interim periods beginning after December 15, 2017. The Company will adopt this guidance January 1, 2018. Since the Company’s revenue is related to leasing activities, the adoption of this guidance will not have a material impact on the consolidated financial statements. The new guidance is applicable to service contracts with joint ventures for which the Company earns property management fees, leasing commissions and development and construction fees. The adoption of this new guidance does not change the accounting for these fees as the pattern of recognition of revenue does not change with the new guidance. We will continue to recognize revenue over time on these contracts because the customer simultaneously receives and consumes the benefits provided by our performance. Thus, the analysis of our contracts under the new revenue recognition standard is consistent with our current revenue recognition model.

~~3. Property Acquisitions~~

~~During the nine months ended September 30, 2017, we did not acquire any properties from a third party.~~

4. Properties Held for Sale and Property Dispositions

Properties Held for Sale

~~During the three months ended September 30, 2017, we entered into an agreement to sell the property at 16 Court Street in Brooklyn, New York, for a gross sales price of $171.0 million.~~

As of ~~September 30, 2017, 16 Court Street in Brooklyn, New York and 125 Chubb in Lyndhurst, New Jersey~~March 31, 2021, no properties were classified as held for sale. ~~We closed on the sale of both properties in October 2017.~~

Property Dispositions

The following table summarizes the properties ~~sold~~disposed of during the ~~nine~~three months ended ~~September 30, 2017:~~March 31, 2021:

106 Spring Street (2)	March 2021	Fee Interest	5,928	35.0		(2.8)

(1)Disposition resulted from the buyer exercising its purchase option under a ground lease arrangement.

(2)In the first quarter of 2021, the property was foreclosed on by the lender in conjunction with the related debt extinguishment.

~~(1)~~	~~Sales price represents the gross sales price for a property or the gross asset valuation for interests in a property.~~


~~(2)~~	The gain on sale for 102 Greene Street is net of $0.9 million in employee compensation awards accrued in connection with the realization of the investment gain as a bonus to certain employees that were instrumental in realizing the gain on sale. Additionally, gain on sale amounts do not include adjustments for expenses recorded in subsequent periods.


~~(3)~~	In February 2016, we closed on the sale of 885 Third Avenue. The sale did not meet the criteria for sale accounting and as a result the property remained on our consolidated financial statements until the criteria was met in April 2017.


~~(4)~~	In April 2017, we closed on the sale of a 90% interest 102 Greene Street and had subsequently accounted for our interest in the property as an investment in unconsolidated joint ventures. We sold the remaining 10% interest in September 2017. See Note 6, "Investments in Unconsolidated Joint Ventures".

These loans were purchased at par in April and May 2017 and were in maturity default at the time of acquisition. At the time the loans were purchased, the Company expected to collect all contractually required payments, including interest. In August 2017, the Company determined that it was probable that the loans would not be repaid in full and therefore, the loans were put on non-accrual status. No impairment was recorded as the Company believes that the fair value of the property exceeds the carrying amount of the loans. The loans had an outstanding balance including accrued interest of $259.3 million at the time that they were put on non-accrual status.


~~(4)~~	In September 2014, we acquired a $26.4 million mortgage loan at a $0.2 million discount and a $5.7 million junior mortgage participation at a $5.7 million discount. The junior mortgage participation was a nonperforming loan at acquisition, is currently on non-accrual status and has no carrying value.

In February 2016, we closed on the sale of 885 Third Avenue and retained a preferred equity position in the property. The sale did not meet the criteria for sale accounting under the full accrual method in ASC 360-20, Property, Plant and Equipment - Real Estate Sales. As a result the property remained on our consolidated balance sheet until the criteria was met in April 2017 at which time the property was deconsolidated and the preferred equity investment was recognized.

As of ~~September 30, 2017,~~March 31, 2021, the book value of these investments was $3.7 billion, net of investments with negative book values totaling $92.4 million for which we have an implicit commitment to fund future capital needs.

(2)The joint venture also owns a long-term leasehold interest in the retail space and certain other spaces at 1560 Broadway, which is adjacent to 1552 Broadway.


~~(1)~~	Ownership interest and economic interest represent the Company's interests in the joint venture as of September 30, 2017. Changes in ownership or economic interests, if any, within the current year are disclosed in the notes below.


~~(2)~~	Acquisition date and price represent the date on which the Company initially acquired an interest in the joint venture and the actual or implied gross purchase price for the joint venture on that date. Acquisition date and price are not adjusted for subsequent acquisitions or dispositions of interest.


~~(3)~~	As a result of the sale of a condominium interest in September 2012, Young & Rubicam, Inc., or Y&R, owns floors three through eight at the property. Because the joint venture has an option to repurchase these floors, the gain associated with this sale was deferred.

~~(4)~~

(3)We hold a 32.28% interest in 3 retail units and 1 residential unit at the property and a 16.14% interest in 3 residential units at the property.

(4)The joint venture owns a long-term leasehold interest in the retail space at 650 Fifth Avenue.

(5)In April 2021, we entered into contract to sell our interest in the property. This transaction is expected to close in the second quarter of 2021 subject to customary closing conditions.

(6)In October 2016, we sold a 49% interest in this property. Our interest in the property was sold within a consolidated joint venture owned 90% by the Company and 10% by Stonehenge. The transaction resulted in the deconsolidation of the venture's remaining 51% interest in the property. Our joint venture with Stonehenge remains consolidated resulting in the combined 51% interest being shown within investments in unconsolidated joint ventures on our balance sheet. In April 2021, we entered into contract to sell our interest in the property. In connection with this contract, we recorded a charge of $5.7 million, which is included in depreciable real estate reserves and impairment in the consolidated statements of operations. This transaction is expected to close in the third quarter of 2021 subject to customary closing conditions.

(7)In 2020, the Company formed a joint venture, which then entered into a long-term sublease with the Company.

(8)In 2020, the Company admitted partners to the One Madison Avenue development project, which resulted in the Company no longer retaining a controlling interest in the entity, as defined in ASC 810, and the deconsolidation of our remaining 50.5% interest. We recorded our investment at fair value, which resulted in the recognition of a fair value adjustment of $187.5 million in 2020 and a fair value adjustment of $2.7 million during the three months ended March 31, 2021. The fair value of our investment was determined by the terms of the joint venture agreement governing the capitalization of the project. The purchase price represents only the purchase of the 1552 Broadway interest which comprised approximately 13,045 square feet. The joint venture also owns a long-term leasehold interest in the retail space and certain other spaces at 1560 Broadway, which is adjacent to 1552 Broadway.


~~(5)~~	~~We hold a 32.28% interest in three retail and two residential units at the property and a 16.14% interest in three residential units at the property.~~

~~(6)~~

The joint venture owns a long-term leasehold interest in the retail space at 650 Fifth Avenue. In connection with the ground lease obligation, SLG provided a performance guaranty and our joint venture partner executed a contribution agreement to reflect its pro rata obligation. In the event the property is converted into a condominium unit and the landlord elects the purchase option, the joint venture shall be obligated to acquire the unit at the then fair value.


~~(7)~~	~~In March 2017, the Company sold a partial interest in the Stonehenge Portfolio as further described under Sale of Joint Venture Interest or Properties below.~~


~~(8)~~	~~The joint venture acquired a leasehold interest in the property in October 2016.~~

~~(9)~~

In October 2016, the Company sold a 49% interest in this property to an investment account managed by BlackRock, Inc. The Company's interest in the property was sold within a consolidated joint venture owned 90% by the Company and 10% by Stonehenge. The transaction resulted in the deconsolidation of the venture's remaining 51% interest in the property. The Company's joint venture with Stonehenge remains consolidated resulting in the combined 51% interest being shown within investments in unconsolidated joint ventures on the Company's balance sheet.


~~(10)~~	In January 2017, the Company admitted two partners, National Pension Service of Korea and Hines Interest LP, into the One Vanderbilt Avenue development project. In April 2017, the criteria for deconsolidation were met, and the development is shown within investments in unconsolidated joint ventures. The

partners have committed aggregate equity to the project totaling no less than ~~$525~~$492.2 million and their ownership interest in the joint venture is based on their capital contributions, up to an aggregate maximum of ~~29.0%~~49.5%. At ~~September 30, 2017~~March 31, 2021, the total of the ~~two~~2 partners' ownership interests based on equity contributed was ~~3.49%~~9.0%.

~~(11)~~

In May 2017, the Company contributed a mezzanine loan secured by a commercial property in midtown Manhattan to a joint venture and retained a 33.33% interest in the venture. The carrying value is net of $10.0 million that was sold, which is included in other assets and other liabilities on the consolidated balance sheets as a result of the transfers not meeting the conditions for sale accounting. In October 2017, the initial maturity date of November 2017 was extended to November 2018.

~~Acquisition, Development and Construction Arrangements~~

Based on the characteristics of the following arrangements, which are similar to those of an investment, combined with the expected residual profit of not greater than 50%, we have accounted for these debt and preferred equity investments under the equity method. As of September 30, 2017 and December 31, 2016, the carrying value for acquisition, development and construction arrangements were as follows (in thousands):

Restrictive Covenants

The terms of the ~~2012~~2017 credit facility ~~as amended,~~ and certain of 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, 2017~~March 31, 2021 and ~~2016,~~December 31, 2020, 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 125 basis points over the three-month LIBOR. ~~The effective weighted average interest rate for the quarter ended September 30, 2017 was 2.52%.~~ Interest payments may be deferred for a period of up to ~~eight~~8 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.

One Vanderbilt Investment

In December 2016, we entered into agreements with entities owned and controlled by our Chairman and CEO, Marc Holliday, and our President, Andrew Mathias, pursuant to which they agreed to make an investment in our One Vanderbilt project at the appraised fair market value for the interests acquired. This investment entitles these entities to receive approximately 1.50% - 1.80% and 1.00% - 1.20%, respectively, of any profits realized by the Company from its One Vanderbilt project in excess of the Company’s capital contributions. The entities have no right to any return of capital. Accordingly, subject to previously disclosed repurchase rights, these interests will have no value and will not entitle these entities to any amounts (other than limited distributions to cover tax liabilities incurred) unless and until the Company has received distributions from the One Vanderbilt project in excess of the Company’s aggregate investment in the project. In the event that the Company does not realize a profit on its investment in the project (or would not realize a profit based on the value at the time the interests are repurchased), the entities owned and controlled by Messrs.

13. Partners' Capital of the Operating Partnership

The Company is the sole managing general partner of the Operating Partnership and at ~~September 30, 2017~~March 31, 2021 owned ~~97,445,509~~69,353,606 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~~1 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~~1 share of common stock is generally the economic equivalent of ~~one~~1 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.

SL Green Realty Corp. and ~~Restated 2005 Stock Option and Incentive Plan~~SL Green Operating Partnership, L.P.

(unaudited)

The Fourth Amended and Restated 2005 Stock Option and Incentive Plan, or the 2005 Plan, was approved by the Company's board of directors in April 2016 and its stockholders in June 2016 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 27,030,000 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) ~~granted after the effective date of the Fourth Amendment 2005 Plan~~ counting as 3.74 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 0.73 fungible units per share subject to such awards, and (3) all other awards (e.g., ~~ten-year~~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 fourth amendment and restatement in June 2016 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 27,030,000 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 ~~SL Green's~~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 2, 2026, 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, 2017, 8.7~~March 31, 2021, 1.9 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, including, among others, outstanding~~Units.

Stock Options and Class O LTIP Units ~~issued under our 2014 Outperformance Plan.~~

Options are granted ~~under the plan~~ 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 with the following weighted average assumptions for grants~~information.

There were 0 options granted during the ~~nine~~three months ended ~~September 30, 2017 and~~March 31, 2021 or the year ended December 31, ~~2016.~~2020.

have a discount from ~~SL Green's~~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.

For the three months ended March 31, 2021, $0.5 million ~~and $15.1 million, respectively.~~

~~2014 Outperformance Plan~~

In August 2014, the compensation committee of the Company's board of directors approved the general terms of the SL Green Realty Corp. 2014 Outperformance Plan, or the 2014 Outperformance Plan. Participants in the 2014 Outperformance Plan may earn, in the aggregate, upwas capitalized to 610,000 LTIP Units in our Operating Partnership based on our total return to stockholders for the three-year period beginning September 1, 2014. Under the 2014 Outperformance Plan, two-thirds of the LTIP Units may be earned based on the Company’s absolute total return to stockholders and one-third of the LTIP Units may be earned based on relative total return to stockholders compared to the constituents of the MSCI REIT Index. Awards earned based on absolute total return to stockholders will be determined independently of awards earned based on relative total return to stockholders. In the event the Company’s performance reaches either threshold before the end of the three-year performance period, a pro-rata portion of the maximum award may be earned. For each component, if the Company’s performance reaches the maximum threshold beginningassets associated with the 19th month of the performance period, participants will earn one-third of the maximum award that may be earned for that component. If the Company’s performance reaches the maximum threshold during the third year of the performance period for a component, participants will earn two-thirds (or an additional one-third) of the maximum award that may be earned for that component. LTIP Units earned under the 2014 Outperformance Plan will be subject to continued vesting requirements, with 50% of any awards earned vesting on August 31, 2017 and the remaining 50% vesting on August 31, 2018, subject to continued employment with us through such dates. Participants will not be entitled to distributions with respect to LTIP Units granted under the 2014 Outperformance Plan unless and until they are earned. If LTIP Units are earned, each participant will also be entitled to the distributions that would have been paid had the number of earned LTIP Units been issued at the beginning of the performance period, with such distributions being paid in the form of cash or additional LTIP Units. Thereafter, distributions will be paid currently with respect to all earned LTIP Units, whether vested or unvested.

The cost of the 2014 Outperformance Plan ($29.2 million, subject to forfeitures), based on the portion of the 2014 Outperformance Plan granted as of September 30, 2017, will be amortized into earnings through the final vesting period. We recorded compensation expense ~~of $1.9 million~~related to our long-term compensation plans, restricted stock and ~~$8.2 million for~~stock options. For the three ~~and nine~~ months ended ~~September 30, 2017, respectively,~~March 31, 2020, $0.6 million was capitalized to assets associated with compensation expense related to ~~the 2014 Outperformance Plan. We recorded~~our long-term compensation ~~expense of $1.8 million~~plans, restricted stock and ~~$6.6 million for the three and nine months ended September 30, 2016, respectively, related to the 2014 Outperformance Plan.~~stock options.

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 ~~SL Green's~~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~~three months ended ~~September 30, 2017, 11,510~~March 31, 2021, 18,290 phantom stock units and ~~9,171~~12,064 shares of common stock were issued to our board of directors. We recorded compensation expense of ~~$0.1 million and $2.2~~$1.8 million during the three ~~and nine~~ months ended September 30, 2017, respectively, related to the Deferred Compensation Plan. We recorded compensation expense of $0.1 million and $1.9 million during the three and nine months ended September 30, 2016, respectively, related to the Deferred Compensation Plan.

~~As of September 30, 2017, there were 98,637 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 encourage our employees ~~to increase their efforts~~ to make our business more successful by providing 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, 2017, 101,882~~March 31, 2021, 157,576 shares of ~~SL Green's~~our common stock had been issued under the ESPP.

16. Fair Value Measurements

We are required to disclose fair value information with regard to 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 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.

We ~~determine other than temporary impairment in~~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 January 2021, pursuant to the partnership documents of our 885 Third Avenue investment, certain participating rights of the common member expired. As ~~of September 30, 2017, we held notes receivable totaling $250.0 million, which were purchased at par, and were in maturity default at the time of acquisition. In August 2017, the Company~~a result, it was determined that itthis investment is a VIE of which we are the primary beneficiary, and the investment was ~~probable that~~consolidated in our financial statements. Upon consolidating the ~~loans would not be repaid in full~~entity, the assets and ~~therefore, the loans were put on non-accrual status. The Company has initiated proceedings to foreclose on the property, and expects to take control~~liabilities of the ~~property unless the buyer is able to repay the principal~~entity were recorded at fair value. This fair value was determined using a third party valuation which primarily utilized cash flow projections that apply, among other things, estimated revenue and ~~interest, including default interest~~expense growth rates, discount rates and ~~fees, on the notes receivable in full prior to the completion~~capitalization rates, as well as sales comparison approach, which utilizes comparable sales, listings and sales contracts. All of ~~the foreclosure process. We believe the collateral value is sufficient to recover the carrying amounts of the notes receivable.~~which are classified as Level 3 inputs.

~~The marketable~~Marketable securities classified as Level 1 ~~were~~are derived from quoted prices in active markets. The valuation technique used to measure the fair value of ~~the~~ 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. ~~Marketable securities in an unrealized loss position are not considered to be other than temporarily impaired.~~ 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 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~~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, such as interest rate swaps, caps, collar and floors, to manage, or hedge 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 ~~sheets~~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. The ineffective portion of a derivative's change in fair value will be immediately~~ 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 at ~~September 30, 2017~~March 31, 2021 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 ~~(amounts~~(dollars in thousands).

Gains and losses on terminated hedges are included in accumulated other comprehensive ~~loss,~~income (loss), and are recognized into earnings over the term of the related mortgage obligation. Over time, the realized and unrealized gains and losses held in accumulated other comprehensive loss 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 ~~$0.8~~$16.6 million of the current balance held in accumulated other comprehensive loss will be reclassified into interest expense and ~~$0.3~~$2.2 million of the portion related to

~~Reconciliation of Net Income to Same-Store Operating Income~~

The Company presents Same-Store Operating Income because the Company believes that this measure, when taken together with the corresponding GAAP financial measures and our reconciliation, provides investors with meaningful information regarding the operating performance of properties. When operating performance is compared across multiple periods, the investor is provided with information not immediately apparent from net income that is determined in accordance with GAAP. Same-Store Operating Income provides information on trends in the revenue generated and expenses incurred in operating our properties, unaffected by the cost of leverage, depreciation, amortization, and other net income components. The Company uses this metric internally as a performance measure. This measure is not an alternative to net income (determined in accordance with GAAP) and same-store performance should not be considered an alternative to GAAP net income performance.

~~For properties owned since January 1, 2016 and still owned and operated at September 30, 2017, Same-Store Operating Income is determined as follows (in millions):~~

Results of Operations

The COVID-19 pandemic has caused, and continues to cause, severe disruptions with wide ranging impacts to the global economy and everyday life. Our business, results of operations, liquidity, cash flows, prospects, and our ability to achieve forward-looking targets and expectations could be materially and adversely affected for at least the duration of the COVID-19 pandemic and likely longer. This could also cause significant volatility in the trading prices of our securities. The extent of the impact of the COVID-19 pandemic will depend on future developments, including the duration, severity and spread of the pandemic, health and safety actions taken to contain its spread including vaccination efforts, and how quickly and to what extent normal economic and operating conditions can resume. Additionally, the COVID-19 pandemic could increase the magnitude of many of the other risks described in our latest Annual Report on Form 10-K and our other SEC filings and may have other adverse effects on our operations that we are not currently able to predict.

Rental ~~Escalation and Reimbursement Revenues~~Revenue

Rental revenues decreased primarily ~~as a result of~~due to a) our Disposed Properties ($~~26.4~~15.7 million), ~~which included the effect of the partial sale and deconsolidation of 11~~b) One Madison Avenue being vacated in the ~~third~~first quarter of ~~2016~~2020 pursuant to the property's redevelopment ($~~16.7~~5.0 million), partially offset by increased rental revenue at our Same-Store Properties ($22.1 million). Increased rental revenue at our Same-Store Properties was primarily driven by 1515 Broadway which, in 2016, recognized accounting write-offs ($17.4 million) related to the space previously leased to Aeropostale following the tenant's bankruptcy.

~~Escalation~~ and ~~reimbursement revenue decreased primarily as a result of Disposed Properties ($2.5 million) and~~c) lower ~~recoveries at~~contribution from our Same-Store properties ($~~5.8~~12.0 million) driven by increased vacancy at 1185 Avenue of the Americas ($4.1 million) and 485 Lexington Avenue ($2.6 million).

Investment Income

For the three months ended ~~September 30, 2017,~~March 31, 2021, investment income decreased primarily as a result of ~~additional income recognized from the recapitalization of~~ a ~~debt investment ($41.0 million)~~decrease in the ~~third quarter of 2016, partially offset by a larger~~ weighted average ~~book~~ balance and ~~an increase in the LIBOR benchmark rate.~~weighted average yield of our debt and preferred equity investments. For the three months ended ~~September 30, 2017,~~March 31, 2021 and 2020, the weighted average debt and preferred equity investment balance outstanding and weighted average yield were ~~$2.0~~$1.1 billion and ~~9.4%, excluding our investment in Two Herald Square which was put on non-accrual in August 2017, respectively,~~6.8% compared to ~~$1.4~~$1.8 billion and ~~9.4%~~8.3%, respectively, for the same period in 2016. As of September 30, 2017, the debt and preferred equity investments had a weighted average term to maturity of 2.3 years excluding extension options and our investment in Two Herald Square.respectively.

Other Income

Other income ~~increased~~decreased primarily ~~as a result~~due to the receipt of ~~construction management and other fees earned~~incremental income from Credit Suisse at One Madison Avenue in the ~~One Vanderbilt venture~~first quarter of 2020 ($~~0.5~~45.2 million), compared to lease termination income in ~~2017.~~the first quarter of 2021 ($9.9 million).

Table of Contents

Property Operating Expenses

Property operating expenses decreased primarily due to a reduction in variable operating expenses, such as utilities, cleaning, and security, at our Same-Store properties ($6.5 million) as a result of lower physical occupancy at the ~~effect of~~properties during the ~~partial sale and deconsolidation of 11 Madison Avenue ($3.7 million) in the third~~first quarter of ~~2016,~~2021 related to COVID-19 and ~~the partial sale of 400 East 57th Street ($1.6 million) in the fourth quarter of 2016, offset by increased~~decreased operating expenses and real estate taxes at our ~~Same-Store Properties~~Disposed properties ($~~2.9 million).~~

~~Table of Contents~~

~~Transaction Related Costs~~

~~The decrease in transaction related costs in 2017 is primarily due to the adoption of ASU No. 2017-01 in 2017, which clarified the definition of a business~~3.6 million and provided guidance to assist in determining whether transactions should be accounted for as acquisitions of assets or businesses. Following the adoption of the guidance, most of our real estate acquisitions are considered asset acquisitions and transaction costs are therefore capitalized to the investment basis when they would have previously been expensed under the previous guidance. Transaction costs expensed in 2017 relate primarily to deals that are not moving forward for which any costs incurred are expensed.$3.7 million, respectively).

Marketing, General and Administrative Expenses

Marketing, general and administrative expenses increased to $22.9 million for the three months ended September 30, 2017 were $24.0 million, or 5.1% of total combined revenues, including our share of joint venture revenues, and an annualized 51 basis points of total combined assets, including our share of joint venture assetsMarch 31, 2021, compared to ~~$25.5~~$19.6 million ~~or 5.2%~~for the same period in 2020 due to an increase in share-based compensation expense as a result of ~~total revenues including our share of joint venture revenues, and 55 basis points of total assets including our share of joint venture assets for 2016.~~stock price volatility.

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 primarily as a result of ~~the Disposed Properties~~lower interest expense from senior unsecured notes ($~~10.7 million) which included the deconsolidation of 11 Madison in the third quarter of 2016 ($6.4~~5.4 million), ~~partially offset by a higher weighted average balance of~~ the ~~2012~~2017 revolving credit facility ($~~2.1~~4.5 million), and term loans ($3.4 million) resulting from a ~~higher weighted~~decrease in the average ~~balance of~~LIBOR rate during the ~~2012 term loan facility ($1.6 million).~~three months ended March 31, 2021 compared to the three months ended March 31, 2020. The weighted average consolidated debt balance outstanding was ~~$6.7~~$5.4 billion for the three months ended ~~September 30, 2017~~March 31, 2021, compared to ~~$7.2~~$6.1 billion for the three months ended ~~September 30, 2016.~~March 31, 2020. The consolidated weighted average interest rate was ~~3.98%~~2.88% for the three months ended ~~September 30, 2017~~March 31, 2021, as compared to ~~4.00%~~3.62% for the three months ended ~~September 30, 2016.~~March 31, 2020.

Depreciation and Amortization

Depreciation and amortization decreased due to depreciation and amortization at our Same Store properties ($6.7 million) and Disposed properties ($2.7 million), partially offset by the increased depreciation and amortization at our Acquired properties ($5.0 million).

Equity in Net Loss from Unconsolidated Joint Ventures

Equity in net loss from unconsolidated joint ventures decreased primarily as a result of ~~the Disposed Properties~~lower depreciation expense at certain unconsolidated joint venture properties ($~~11.0 million), the acquisition of 110 Greene Street ($5.6 million) and starting the redevelopment of 5-7 Dey Street, 183 & 187 Broadway in 2017 ($5.1~~6.7 million).

~~Equity in Net Income in Unconsolidated Joint Venture~~

Equity in net ~~income from~~loss on sale of interest in unconsolidated joint ventures increased primarily as a result of additional depreciation expense from the deconsolidation of 11 Madison Avenue ($10.4 million) in 2016, partially offset by the repayment of a debt position held in an unconsolidated joint venture ($1.5 million).

~~Equity in Net Gain on Sale of Interest in Unconsolidated Joint Ventures/Real Estate~~venture/real estate

During the three months ended ~~September 30, 2017,~~March 31, 2021, we recognized a loss on sale related to our interests in 55 West 46th Street ($15.2 million). During the three months ended March 31, 2020, we did not sell any joint venture interests or properties.

Purchase price and other fair value adjustments

During the three months ended March 31, 2021, we recorded $2.7 million of purchase price and other fair value adjustments related to One Madison Avenue. During the three months ended March 31, 2020, we did not record any purchase price and other fair value adjustments.

(Loss) gain on sale of real estate, net

During the three months ended March 31, 2021, we recognized a loss on sale related to our interest in 712 Madison Avenue ($1.4 million). During the three months ended March 31, 2020, we recognized a gain on sale related to our interest in ~~102 Greene~~315 West 33rd Street ("The Olivia") ($~~0.3~~72.3 million).

~~Rental, Escalation and Reimbursement Revenues~~

Rental revenues decreased primarily as a result of Disposed Properties ($244.4 million), which included 388-390 Greenwich Street and the effect of the partial sale and deconsolidation of 11 Madison Avenue in the third quarter of 2016, partially offset by increased rental revenue at our Same-Store Properties ($37.0 million). Increased rental revenue at Same-Store Properties was primarily driven by 1515 Broadway which, in 2016, recognized accounting write-offs ($17.4 million) related to the space previously leased to Aeropostale following the tenant's bankruptcy, 919 Third Avenue ($7.8 million), and 711 Third Avenue ($7.7 million).

~~Investment Income~~

For the nine months ended September 30, 2017, investment income decreased primarily as a result of additional income recognized from the recapitalization of a debt investment ($41.0 million) in the third quarter of 2016, partially offset by previously unrecognized income related to our preferred equity investment in 885 Third Avenue ($14.3 million), a larger weighted average book balance and an increase in the LIBOR benchmark rate. For the nine months ended September 30, 2017, the weighted average debt and preferred equity investment balance outstanding and weighted average yield were $1.9 billion and 9.3% excluding our investment in Two Herald Square which was put on non-accrual in August 2017, respectively, compared to $1.5 billion and 9.8%, respectively, for the same period in 2016. As of September 30, 2017, the debt and preferred equity investments had a weighted average term to maturity of 2.3 years excluding extension options and our investment in Two Herald Square.

~~Other Income~~

Other income decreased primarily as a result of the termination fee earned in connection with the termination of the lease with Citigroup, Inc. at 388-390 Greenwich in 2016 ($94.0 million) and promote income earned in connection with the sale of 33 Beekman in the second quarter of 2016 ($10.8 million). The decrease was partially offset by net fees recognized in connection with the One Vanderbilt venture in 2017 ($10.8 million).

~~Table of Contents~~

~~Property Operating Expenses~~

~~Property operating expenses decreased primarily as a result of Disposed Properties ($26.7 million) offset by increased real estate taxes at our Same-Store Properties ($8.0 million).~~

~~Transaction Related Costs~~

The decrease in transaction related costs in 2017 is primarily due to the adoption of ASU No. 2017-01 in 2017, which clarified the definition of a business and provided guidance to assist in determining whether transactions should be accounted for as acquisitions of assets or businesses. Following the adoption of the guidance, most of our real estate acquisitions are considered asset acquisitions and transaction costs are therefore capitalized to the investment basis when they would have previously been expensed under the previous guidance. Transaction costs expensed in 2017 related primarily to deals that are not moving forward for which any costs incurred are expensed.

~~Marketing, General and Administrative Expenses~~

Marketing, general and administrative expenses for the nine months ended September 30, 2017 were $72.4 million, or 5.1% of total combined revenues, including our share of joint venture revenues, and annualized 52 basis points of total combined assets, including our share of joint venture assets compared to $74.0 million, or 4.4% of total revenues including our share of joint venture revenues, and 53 basis points of total assets including our share of joint venture assets for 2016.

~~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 primarily as a result of the Disposed Properties ($64.5 million). The weighted average consolidated debt balance outstanding was $6.6 billion for the nine months ended September 30, 2017 compared to $9.1 billion for the nine months ended September 30, 2016. The consolidated weighted average interest rate was 4.02% for the nine months ended September 30, 2017 as compared to 3.79% for the nine months ended September 30, 2016.

~~Depreciation and Amortization~~

~~Depreciation and amortization decreased primarily as a result of the Disposed Properties ($440.5 million), partially offset~~

~~by accelerated amortization at 5-7 Dey Street, 183 & 187 Broadway upon the commencement of demolition of the properties ($39.9 million).~~

~~Equity in Net Income in Unconsolidated Joint Venture~~

Equity in net income from unconsolidated joint ventures increased primarily as a result of higher net income contributions from 1745 Broadway ($6.4 million) in 2017, partially offset by a reduced occupancy at 3 Columbus Circle ($3.5 million).

~~Equity in Net Gain on Sale of Interest in Unconsolidated Joint Ventures/Real Estate~~

During the nine months ended September 30, 2017, we recognized a gain on sale related to our interests in 747 Madison Avenue ($13.0 million), part of our interest in the Stonehenge Portfolio ($0.9 million), and 102 Greene Street ($0.3 million). The sale of 747 Madison, which occurred in 2014, did not meet the criteria for sale accounting at that time and, therefore, remained on our consolidated financial statement until the criteria was met in the second quarter of 2017. During the nine months ended September 30, 2016, we recognized a gain on the sale related to our interests in 33 Beekman ($33.0 million), 7 Renaissance Square ($4.2 million), 1 Jericho ($3.3 million) and EOP Denver ($2.8 million).

~~Gain (loss) on sale of real estate, net~~

During the nine months ended September 30, 2017, we recognized a loss on the sale of 885 Third Avenue ($8.8 million) which closed in 2016, but was only recognized in the second quarter of 2017 due to the sale not meeting the criteria for sale accounting under the full accrual method in ASC 360-20 until the second quarter of 2017. This loss was partially offset by a gain on sale associated with the partial sale of the property at 102 Greene Street ($4.9 million). During the nine months ended September 30, 2016, we recognized gains on sale associated with the sale of the property at 388-390 Greenwich ($206.5 million) and 248-252 Bedford Avenue in Brooklyn, New York ($15.3 million), which were partially offset by the sale loss on sale of 7 International Drive, Westchester County, NY ($6.9 million).

~~Depreciable Real Estate Reserves~~

During the nine months ended September 30, 2017, we recorded a $85.3 million charge related to 125 Chubb Avenue in Lyndhurst, NJ, Stamford Towers and 520 White Plains Road in Tarrytown, NY. During the nine months ended September 30, 2016,March 31, 2021, we recognized depreciable real estate reserves and impairments related to ~~500 West Putnam~~a) 400 East 57th Street ($~~10.4~~5.7 million), and b) 106 Spring Street ($2.7 million), as offset by c) 133 Greene Street ($0.2 million). During the three months ended March 31, 2020, we did not record any recognize any depreciable real estate reserves.

Loan loss and other investment reserves, net of recoveries

During the three months ended March 31, 2021 we did not recognize any loan loss and other investment reserves. During the three months ended March 31, 2020, we recorded $11.2 million of loan loss and other investment reserves in conjunction with recording debt and preferred equity investments and other financing receivables at the net amount expected to be collected.

Liquidity and Capital Resources

We currently expect that our 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 repurchases, dividends to shareholders, distributions to unitholders, repurchases or repayments of outstanding indebtedness ~~(which may include exchangeable debt)~~ and for debt and preferred equity investments will include:


~~(1)~~	~~Cash flow from operations;~~


~~(2)~~	~~Cash on hand;~~


~~(3)~~	~~Borrowings under the 2012 credit facility;~~


~~(4)~~	~~Other forms of secured or unsecured financing;~~


~~(5)~~	~~Net proceeds from divestitures of properties and redemptions, participations and dispositions of debt and preferred equity investments; and~~


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

(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.

As of the date of this filing, we have collected gross tenant billings for the first quarter of 2021 of 96.9% overall, including 98.9% from office tenants and 90.9% from retail tenants.

~~(1)~~	The $269.0 million of 3.00% convertible notes which matured in October 2017 became exchangeable commencing September 14, 2017 and the Operating Partnership elected to settle exchanges in cash. In October 2017, all note holders elected to exchange the notes and the notes were repaid for $350.8 million.

As of ~~September 30, 2017,~~March 31, 2021, we had ~~$270.3 million~~liquidity of $1.2 billion, comprised of $0.9 billion of availability under our revolving credit facility and $0.3 billion of consolidated cash on hand, inclusive of ~~$28.8~~$23.8 million of marketable securities. ~~We expect to generate positive~~This liquidity excludes $96.2 million representing our share of cash ~~flow from operations for the foreseeable future.~~at unconsolidated joint venture properties. We may seek to divest of properties, or 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 obligations, as described above, upon maturity, if not before.

We ~~also~~ have investments in several real estate joint ventures with various partners who we consider to be financially stable and who have the ability to fund a capital call when needed. 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 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.

Capitalization

Our authorized capital stock consists of 260,000,000 shares, $0.01 par value per share, consisting of 160,000,000 shares of common stock, $0.01 par value per share, 75,000,000 shares of excess stock, at $0.01 par value per share, and 25,000,000 shares of preferred stock, $0.01 par value per share. As of ~~September 30, 2017, 97,445,509~~March 31, 2021, 69,353,606 shares of common stock and no shares of excess stock were issued and outstanding.

Table of ~~September 30, 2017, SL Green~~Contents

On December 4, 2020 our Board of Directors declared an ordinary dividend and a special dividend (together, "the Total Dividend"). The Total Dividend was paid on January 15, 2021 to shareholders of record at the close of business on December 15, 2020 ("the Record Date"). Shareholders had ~~9,200,000~~the opportunity to elect to receive the Total Dividend in the form of all cash or all stock, subject to proration if either option was oversubscribed. Shareholders who elected to receive cash received, for each share of common stock they owned as of the Record Date, approximately $0.3735 in cash and 0.0279 shares of common stock. Shareholders who elected to receive shares received, for each share of common stock they owned as of the Record Date, approximately 0.0343 shares of common stock. The number of shares issued was calculated based on the volume weighted average trading price of SLG's common stock between January 5-7, 2021, of $58.15 per share.

To mitigate the dilutive impact of the common stock issued in the special dividend, the board of directors also authorized a reverse stock split, which was effective after markets closed on January 20, 2021. On January 8, 2021, a committee of the Board of Directors calculated the ratio for the reverse stock split of our issued and outstanding shares of common stock as 1.02918-for-1. After the issuance of the dividend and the completion of the reverse stock split, the number of shares of our ~~6.50% Series I Cumulative Redeemable Preferred Stock,~~common stock outstanding was equivalent to the number of total shares outstanding on the Record Date (not including any issuances or ~~Series I Preferred Stock, outstanding. In addition, persons other than~~repurchases that occurred following the ~~Company held Preferred Units~~Record Date, as well as any fractional shares that would have been issued but for which cash-in-lieu was paid). However, on a relative basis, some individual shareholders may have more shares of ~~limited partnership interests~~SLG’s common stock, and some individual shareholders may have fewer shares of our common stock, depending on their individual elections to receive cash or stock and as a result of the cash option being oversubscribed.

Share Repurchase Program

In August 2016, our ~~board~~Board of ~~directors~~Directors approved a ~~stock~~$1.0 billion share repurchase ~~plan~~program under which we can buy ~~up to $1.0 billion of~~ shares of our common stock. The Board of Directors has since authorized five separate $500.0 million increases to the size of the share repurchase program in the fourth quarter of 2017, second quarter of 2018, fourth quarter of 2018, fourth quarter of 2019, and fourth quarter of 2020 bringing the total program size to $3.5 billion.

At ~~September 30, 2017,~~March 31, 2021, share repurchases, ~~made~~excluding the redemption of OP units, executed under the ~~stock repurchase plans~~program were as follows:


Period	Shares repurchased	Average price paid per share	Cumulative number of shares repurchased as part of the repurchase plan or programs

Fourth Amended and Restated 2005 Stock Option and Incentive Plan

The Fourth Amended and Restated 2005 Stock Option and Incentive Plan, or the 2005 Plan, was approved by the Company's board of directors in April 2016 and its stockholders in June 2016 at the Company's annual meeting of stockholders. Subject to adjustments upon certain corporate transactions or events, awards with respect to up to a maximum of 27,030,000 fungible units may be granted as options, restricted stock, phantom shares, dividend equivalent rights and other equity-based awards under the

~~2012~~2017 Credit Facility

In November 2017, we entered into an amendment to the credit facility, referred to as the 2017 credit facility, that was originally entered into by the Company in November 2012, or the 2012 credit facility. As of ~~September~~March 31, 2021, the 2017 credit facility consisted of a $1.5 billion revolving credit facility, a $1.3 billion term loan (or "Term Loan A"), and a $200.0 million term loan (or "Term Loan B") with maturity dates of March 31, 2022, March 31, 2023, and November 21, 2024, respectively. The revolving credit facility has two six-month as-of-right extension options to March 31, 2023. 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 March 31, 2021, the 2017 credit facility bore interest at a spread over 30-day LIBOR ranging from (i) 82.5 basis points to 155 basis points for loans under the revolving credit facility, (ii) 90 basis points to 175 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.

At March 31, 2021, the applicable spread was 100 basis points for the revolving credit facility, 110 basis points for Term Loan A, and 100 basis points for Term Loan B. We are required to pay quarterly in arrears a 12.5 to 30 ~~2017,~~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 March 31, 2021, the facility fee was 20 basis points.

As of March 31, 2021, we had ~~$80.8~~$16.5 million of outstanding letters of credit, ~~$280.0~~$630.0 million drawn under the revolving credit facility and ~~$1.2~~$1.5 billion outstanding under the term loan ~~facility,~~facilities, with total undrawn capacity of ~~$1.2~~$0.9 billion under the ~~2012~~2017 credit facility. At ~~September 30, 2017~~March 31, 2021 and December 31, ~~2016,~~2020, the revolving credit facility had a carrying value of ~~$275.8~~$625.8 million and ~~$(6.3)~~$105.3 million, respectively, net of deferred financing costs. ~~The December~~At March 31, ~~2016 carrying value represents deferred financing costs and is presented within other liabilities. At September 30, 2017~~2021 and December 31, ~~2016,~~2020, the term loan ~~facility~~facilities had a carrying value of ~~$1.2~~$1.5 billion and ~~$1.2~~$1.5 billion, respectively, net of deferred financing costs.

The Company and the Operating Partnership are borrowers jointly and severally obligated under the 2017 credit facility.

The 2017 credit facility includes certain restrictions and covenants (see Restrictive Covenants below).

Restrictive Covenants

The terms of the ~~2012~~2017 credit facility ~~as amended,~~ and certain of 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, 2017~~March 31, 2021 and ~~2016,~~December 31, 2020, we were in compliance with all such 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 either the use of interest rate derivative instruments and/or through our variable rate debt and preferred equity investments. ABased on the debt outstanding as of March 31, 2021, a hypothetical 100 basis point increase in ~~interest rates along~~ the ~~entire~~floating rate interest rate curve ~~for 2017~~ would increase our consolidated annual interest cost, net of interest income from variable rate debt and preferred equity investments, by ~~$1.0~~$10.0 million and would increase our share of joint venture annual interest cost by ~~$16.6~~$20.8 million. At ~~September 30, 2017, 59.9%~~March 31, 2021, 32.1% of our ~~$2.0~~$1.1 billion debt and preferred equity portfolio is indexed to LIBOR.

We recognize most derivatives on the balance sheet at fair value. Derivatives that are not hedges are adjusted to fair value through income. If a derivative is considered 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 hedged asset, liability, or firm commitment through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. ~~The ineffective portion of a derivative's change in fair value is immediately recognized in earnings.~~

Our long-term debt of ~~$5.2~~$3.9 billion bears interest at fixed rates, and therefore the fair value of these instruments is affected by changes in the market interest rates. Our variable rate debt and variable rate joint venture debt as of ~~September 30, 2017~~March 31, 2021 bore interest based on a spread of LIBOR plus ~~125~~100 basis points to LIBOR plus ~~417~~340 basis points.

Contractual Obligations

Refer to our ~~2016~~2020 Annual Report on Form 10-K for a discussion of our contractual obligations. There have been no material changes, outside the ordinary course of business, to these contractual obligations during the three ~~and nine~~ months ended ~~September 30, 2017.~~March 31, 2021.

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. ~~Substantially all~~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.

Table of Contents

Capital Expenditures

We estimate that for the remainder of the year ending December 31, ~~2017,~~2021, we expect to incur ~~$66.9~~$75.0 million of recurring capital expenditures on existing consolidated properties and ~~$14.6~~$174.6 million of development or redevelopment expenditures ~~net of loan reserves, (including tenant improvements and leasing commissions)~~ on existing consolidated properties, ~~and~~of which $56.0 million will be funded by construction financing facilities. We expect our share of capital expenditures at our joint venture properties ~~net of loan reserves,~~ will be ~~$109.5 million.~~$220.0 million, of which $185.9 million will be funded by construction financing facilities. 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. We expect to fund these capital expenditures with operating cash flow, existing liquidity, or incremental borrowings. We expect our capital needs over the next twelve months and thereafter will be met through a combination of cash on hand, net cash provided by operations, potential asset sales, borrowings or additional equity or debt issuances.

Dividends/Distributions

We expect to pay cash dividends to our stockholders based on the distributions we receive from our Operating Partnership, ~~primarily from~~which are generated by the collection of property revenues, net of operating expenses, ~~or, if necessary, from working capital.~~and interest on our debt and preferred equity portfolio.

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. ~~We intend~~

Any dividend we pay may be in the form of cash, stock or a combination thereof, subject to ~~continue~~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 ~~pay regular quarterly dividends to~~maintain our ~~stockholders. Based on our current annual dividend rate of $3.10 per share, we would pay $316.2 million in dividends to SL Green's common stockholders on an annual basis.~~ 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 ~~2012~~2017 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 three property insurance programs and liability insurance. ~~Management believes the policy specifications and insured limits are appropriate given the relative risk of loss, the cost of the coverage, and industry practice.~~ Separate property and liability coverage may be purchased on a stand-alone basis for certain assets, such as ~~the~~ development projects. Additionally, one of ~~One Vanderbilt.~~

On January 12, 2015, the Terrorism Risk Insurance Program Reauthorization and Extension Act of 2007 ("TRIPRA") (formerly the Terrorism Risk Insurance Act) was reauthorized until December 31, 2020 pursuant to the Terrorism Insurance Program Reauthorization and Extension Act of 2015. The TRIPRA extends the federal Terrorism Insurance Program that requiresour captive insurance companies, to offer terrorism coverage and provides for compensation for insured losses resulting from acts of certified terrorism, subject to the current program trigger of $120.0 million, which will increase by $20.0 million per annum, commencing December 31, 2015 (Trigger). Coinsurance under TRIPRA is 16%, increasing 1% per annum, as of December 31, 2015 (Coinsurance). There are no assurances TRIPRA will be further extended.

~~Our wholly-owned taxable REIT subsidiary,~~ Belmont Insurance Company, or Belmont, provides coverage for NBCR terrorist acts asabove a specified trigger. Belmont's retention is reinsured by our other captive insurance company, ~~and as one of the elements of our overall insurance program.~~Ticonderoga Insurance Company ("Ticonderoga"). If Belmont was formed in an effort, among other reasons, to stabilize to some extent the impact of insurance market fluctuations. Belmont is licensed by New York State as a direct insurer of Terrorism and NBCR Terrorism, and a reinsurer with respect to portions of our General Liability, Environmental Liability, Flood, Professional Liability, Employment Practices Liability and D&O coverage. Belmont purchases reinsurance for its Coinsurance and is backstopped by the Federal government for the balance of its terrorism limit for certified acts of terrorism above the Trigger. We purchase direct, third party terrorism insurance up to the Trigger for certified acts of terrorism. Belmont is backstopped by the Federal government for certified acts of NBCR terrorism above the Trigger and subject to its Coinsurance, however does not reinsure its NBCR Coinsurance requirement. There is no coverage for a NBCR terrorism act if covered industry lossesor Ticonderoga are below the Trigger. As long as we own Belmont, we are responsible for its liquidity and capital resources, and the accounts of Belmont are part of our consolidated financial statements. If we experience a loss and Belmont is required to pay a claim under our insurance policies, we would ultimately record the loss to the extent of ~~Belmont's~~ required ~~payment. Therefore, certain insurance coverage provided by Belmont should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance.~~

Our debt instruments, consisting of mortgage loans secured by our properties (which are generally non-recourse to us), mezzanine loans, ground leases, our 2012 credit facility, senior unsecured notes and other corporate obligations, contain customary covenants requiring us to maintain insurance. Although we believe that we currently maintain sufficient insurance coverage to satisfy these obligations,payments. However, there is no assurance that in the future we will be able to procure coverage at a reasonable cost. InFurther, 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 ~~instances, there can be no assurance that~~covenants relating to insurance. Belmont and Ticonderoga provide coverage solely on properties owned by the ~~lenders~~Company or ground lessors under these instruments will not take the position that a total or partial exclusion from “all-risk” insurance coverage for losses due to, for example, terrorist acts is a breach of these debt and ground lease instruments allowing the lenders or ground lessors to declare an event of default and accelerate repayment of debt or recapture of ground lease positions. In addition, if lenders require greater coverage that we are unable to obtain at

~~commercially reasonable rates, we may incur substantially higher insurance premiums or our ability to finance our properties and expand our portfolio may be adversely impacted.~~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. We may have less protection than with respect to the properties where we obtain coverage directly. Although we consider our insurance coverage to be appropriate, in the event of a major catastrophe, we may not have sufficient coverage to replace certain properties.

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 ~~the National Association of Real Estate Investment Trusts, or~~ 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 ~~Generally Accepted Accounting Principles, or~~ GAAP), excluding gains (or losses) from sales of properties ~~debt restructurings~~ and real estate related impairment charges, plus real estate related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures.

Table of Contents

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 ~~bonuses~~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 ~~extraordinary items,~~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.

FFO for the three ~~and nine~~ months ended ~~September 30, 2017~~March 31, 2021 and ~~2016~~2020 are as follows (in thousands):

Inflation

Substantially all of our office leases provide for separate real estate tax and operating expense escalations as well as operating expense recoveries based on increases in the ~~Consumer Price Index~~CPI or other measures such as porters' wage. In addition, many of the leases provide for fixed base rent increases. We believe that inflationary increases will be at least partially offset by the contractual rent increases and expense escalations described above.
