EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended March 31, 2019 of SL Green Realty Corp. and SL Green Operating Partnership, L.P. Unless stated otherwise or the context otherwise requires, references to "SL Green Realty Corp.," the "Company" or "SL Green" mean SL Green Realty Corp. and its consolidated subsidiaries, including SL Green Operating Partnership, L.P.; and references to "SL Green Operating Partnership, L.P.," the "Operating Partnership" or "SLGOP" mean SL Green Operating Partnership, L.P. and its consolidated subsidiaries. The terms "we," "our" and "us" mean the Company and all the entities owned or controlled by the Company, including the Operating Partnership.

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

As of March 31, 2019 the Company owns 95.13% of the outstanding general and limited partnership interest in the Operating Partnership and owns 9,200,000 Series I Preferred Units of the Operating Partnership. As of March 31, 2019, noncontrolling investors held, in aggregate, a 4.87% 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.

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.

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 March 31, 2019, noncontrolling investors held, in the aggregate, a 4.87% 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."

As of March 31, 2019, we owned the following interests in properties in the New York metropolitan area, primarily in midtown Manhattan. Our investments located outside of Manhattan are referred to as the Suburban properties:

(1) The weighted average occupancy for commercial properties represents the total occupied square feet divided by total square footage at acquisition. The weighted average occupancy for residential properties represents the total occupied units divided by total available units.

(2) As of March 31, 2019, we owned a building at 315 West 33rd Street, also known as The Olivia, that was comprised of approximately 270,132 square feet (unaudited) of retail space and approximately 222,855 square feet (unaudited) of residential space. For the purpose of this report, we have included this building in the number of retail properties we own. However, we have included only the retail square footage in the retail approximate square footage, and have listed the balance of the square footage as residential square footage.

As of March 31, 2019, we also managed two office buildings owned by third parties encompassing approximately 2.1 million square feet (unaudited), and held debt and preferred equity investments with a book value of $2.3 billion, including $0.1 billion of debt and preferred equity investments and other financing receivables that are included in balance sheet line items other than the Debt and Preferred Equity Investments line item.

Partnership Agreement

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

Basis of Quarterly Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements.

Notes to Consolidated Financial Statements (cont.)

March 31, 2019

(unaudited)

The consolidated balance sheet at December 31, 2018 has been derived from the audited financial statements as of that date but does not include all the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

2. Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include our accounts and those of our subsidiaries, which are wholly-owned or controlled by us. Entities which we do not control through our voting interest 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 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

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 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 to 14 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 to 14 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 a curve based primarily on the observable borrowing rates of the Company, other REITs, and other corporate borrowers with long-term borrowings. On the statements of operations, operating leases are expensed through operating lease rent while financing leases are expensed through amortization and interest expense. On the balance sheet, 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 calculated fair value of the property. 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.

(unaudited)

We recognized $1.2 million and $2.4 million of rental revenue for the three months ended March 31, 2019 and 2018, respectively, for the amortization of aggregate below-market leases in excess of above-market leases and a reduction in lease origination costs, resulting from the allocation of the purchase price of the applicable properties.

The following summarizes our identified intangible assets (acquired above-market leases and in-place leases) and intangible liabilities (acquired below-market leases) as of March 31, 2019 and December 31, 2018 (in thousands):

	March 31, 2019			December 31, 2018
Identified intangible assets (included in other assets):
Gross amount	$	266,540		$	266,540
Accumulated amortization	(244,246		)	(241,040		)
Net(1)	$	22,294		$	25,500
Identified intangible liabilities (included in deferred revenue):
Gross amount	$	276,245		$	276,245
Accumulated amortization	(256,010		)	(253,767		)
Net(1)	$	20,235		$	22,478

(1) As of March 31, 2019, and December 31, 2018, no net intangible assets and no net intangible liabilities, were reclassified to assets held for sale and liabilities related to assets held for sale.

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 March 31, 2019, 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. 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. Any unrealized losses that are determined to be other-than-temporary are recognized in earnings up to their credit component.

At March 31, 2019 and December 31, 2018, we held the following marketable securities (in thousands):

	March 31, 2019		December 31, 2018
Commercial mortgage-backed securities	$	29,406	$	28,638
Total marketable securities available-for-sale	$	29,406	$	28,638

The cost basis of the commercial mortgage-backed securities was $27.5 million at both March 31, 2019 and December 31, 2018. These securities mature at various times through 2035. We held no equity marketable securities as of March 31, 2019 and December 31, 2018.

During the three months ended March 31, 2019, we did not dispose of any marketable securities. During the three months ended March 31, 2018, we did not dispose of any marketable securities.

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 joint ventures' projected discounted cash flows. We do not believe that the values of any of our equity investments were impaired at March 31, 2019.

Deferred Lease Costs

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

Lease Classification

Lease classification for leases under which the Company is the lessor is evaluated at lease commencement and leases not classified as sales-type leases or direct financing leases are classified as operating leases. Leases qualify as sales-type leases if the contract includes either transfer of ownership clauses, certain purchase options, a lease term representing a major part of the economic life of the asset, or the present value of the lease payments and residual guarantees provided by the lessee exceeds substantially all of the fair value of the asset. Additionally, leasing an asset so specialized that it is not deemed to have any value to the Company at the end of the lease term may also trigger sales-type lease classification. Leases would 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 tenant takes possession or controls the physical use of the leased space. In order for the tenant to take possession, the leased space must be substantially ready for its intended use.

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

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

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

The Company provides its tenants with certain customary services for lease contracts such as common area maintenance, general security or snow removal. We have elected to combine the nonlease 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 on sale of real estate assets when we no longer hold a controlling financial interest in the entity holding 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, in the opinion of management, it is deemed collectible. Some debt and preferred equity investments provide for accrual

24

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 ultimately collectible, based on the underlying collateral and operations of the borrower. 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.

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 on any non-accrual debt or preferred equity investment is resumed when such non-accrual debt or preferred equity investment becomes contractually current and performance is demonstrated to be resumed. Interest is recorded as income on impaired loans only to the extent cash is received.

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.

Allowance for Loan Loss and Other Investment Reserves

The expense for loan loss and other investment reserves in connection with debt and preferred equity investments is the charge to earnings to adjust the allowance for possible losses to the level that we estimate to be adequate, based on Level 3 data, considering delinquencies, loss experience and collateral quality.

The Company evaluates debt and preferred equity investments that are classified as held to maturity for possible impairment or 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. Quarterly, the Company assigns each loan a risk rating. Based on a 3-point scale, loans are rated “1” through “3,” from less risk to greater 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.

When it is probable that we will be unable to collect all amounts contractually due, the investment is considered impaired. A valuation allowance is measured based upon the excess of the recorded investment amount over the fair value of the collateral. Any deficiency between the carrying amount of an asset 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 our investment, we will adjust our reserves accordingly.

Debt and preferred equity investments that are classified as held for sale are carried at the lower of cost or fair market value using available market information obtained through consultation with dealers or other originators of such investments as well as discounted cash flow models based on Level 3 data pursuant to ASC 820-10. As circumstances change, management may conclude not to sell an investment designated as held for sale. In such situations, the investment will be reclassified at its net carrying value to debt and preferred equity investments held to maturity. For these reclassified investments, the difference between the current carrying value and the expected cash to be collected at maturity will be accreted into income over the remaining term of the investment.

Income Taxes

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

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

We have elected, and may elect in the future, to treat certain of our corporate subsidiaries as taxable REIT subsidiaries, or TRSs. In general, TRSs may perform non-customary services for the tenants of the Company, hold assets that we cannot hold directly and generally may engage in any real estate or non-real estate related business. The TRSs generate income, resulting in Federal and state income tax liability for these entities.

During the three months ended March 31, 2019, we recorded Federal, state and local tax provisions of $0.8 million. During the three months ended March 31, 2018, we recorded Federal, state and local tax provisions of $0.5 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.

On December 22, 2017, the Tax Cuts and Jobs Act (the ‘‘Tax Act’’) was signed into law and makes substantial changes to the Code. The Tax Act has not had a material impact on our financial statements for the three months ended March 31, 2019.

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 the New York metropolitan area. See Note 5, "Debt and Preferred Equity Investments."

We perform ongoing credit evaluations 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 source of funds to offset the economic costs associated with lost revenue and the costs associated with re-tenanting a space. The properties in our real estate portfolio are located in the New York metropolitan area. The tenants located in our buildings operate in various industries. Other than one tenant, Credit Suisse Securities (USA), Inc., who accounts for 8.2% 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 March 31, 2019.

For the three months ended March 31, 2019, the following properties contributed more than 5.0% of our annualized cash rent, including our share of joint venture annualized cash rent:

Property	Three Months Ended March 31, 2019
11 Madison Avenue	7.4%
1185 Avenue of the Americas	6.7%
420 Lexington Avenue	6.3%
1515 Broadway	6.0%
One Madison Avenue	5.8%

Annualized cash rent for each of our other consolidated properties was below 5.0%.

Reclassification

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

Accounting Standards Updates

In August 2018, the FASB issued Accounting Standard Update (ASU) No. 2018-15, Intangibles - Goodwill and Other- Internal-Use Software (Topic 350-40), Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. The amendments provide guidance on accounting for fees paid when the arrangement includes a software license and align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing costs to develop or obtain internal-use software. The guidance is effective for the Company for fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company has not yet adopted this new guidance and does not expect it to have a material impact on the Company’s consolidated financial statements when the new standard is implemented.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This amendment removed, modified and added the disclosure requirements under Topic 820. The changes are effective for the Company for fiscal years beginning after December 15, 2019. Early adoption is permitted for the removed or modified disclosures with adoption of the additional disclosures upon the effective date. The Company has not yet adopted this new guidance and does not expect it to have a material impact on the Company’s consolidated financial statements when the new standard is implemented.

In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718), Improvements to Nonemployee Share-Based Payment Accounting. This amendment provides additional guidance related to share-based payment transactions for acquiring goods or services from nonemployees. The Company adopted this guidance on January 1, 2019 and it did not have a material impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities, and in July 2018, the FASB issued ASU No. 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. The amendments in the new standards will permit more flexibility in hedging interest rate risk for both variable rate and fixed rate financial instruments. The standards will also enhance the presentation of hedge results in the financial statements. The guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted.

The Company adopted this guidance on January 1, 2019, and it did not have a material 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 and in November 2018 issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. 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 15, 2018. The Company’s DPE portfolio and financing lease assets will be subject to this guidance once the Company adopts it. ASU No. 2018-19 excludes operating lease receivables from the scope of this guidance. The Company continues to evaluate the impact of adopting this new accounting standard on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases. In July 2018, the FASB issued ASU No. 2018-10 - Codification Improvements to Topic 842, Leases, and ASU No. 2018-11 - Targeted Improvements. In December 2018, the FASB issued ASU No. 2018-20 - Narrow-Scope Improvements for Lessors and in March 2019 issued ASU No. 2019-01 - Codification Improvements. The Company adopted this guidance on January 1, 2019 using the modified retrospective approach which allows the Company to apply the guidance for the current year presentation and not adjust the prior year numbers. The Company elected the package of practical expedients that allows an entity to not reassess (i) whether any expired or existing contracts are or contain leases, (ii) lease classification for any expired or existing leases and (iii) initial direct costs for any expired or existing leases. The new guidance applies to the ground leases under which the Company is a lessee. The Company has recognized a new asset and liability - “Right of use asset - operating leases” and “Lease liability - operating leases” - for those leases classified as operating leases under the previous standard. The Company will continue to recognize expense on a straight-line basis for these operating leases. The ground leases that the Company historically reported as “Properties under capital leases” and “Capitalized lease obligations” are now labeled “Right of use asset - financing leases” and “Lease liability - financing leases”. The expense recognition of these leases has not changed. The Company adopted the practical expedient offered in ASU No. 2018-11 that allows lessors to not separate non-lease components from the related lease components under certain conditions. In doing so, the Company has collapsed the line “Escalation and reimbursement revenues” into the “Rental revenue, net” line to reflect adopting this practical expedient. The Company also collapsed the prior year balances to conform to the current year presentation. For future leases, the Company no longer capitalizes internal leasing costs that are not incremental as defined under the new guidance. The Company has recorded an additional expense of approximately $2.2 million related to this change for the first quarter.

3. Property Acquisitions

During the three months ended March 31, 2019, we did not acquire any properties from a third party.

In April 2019, we accepted an assignment of the equity interests in the property located at 106 Spring Street in Manhattan, in lieu of repayment of the Company's debt investment, and recorded the assets received and liabilities assumed at fair value.

4. Properties Held for Sale and Property Dispositions

Properties Held for Sale

As of March 31, 2019, no properties were classified as held for sale.

Property Dispositions

During the three months ended March 31, 2019, we did not sell any properties to a third party.

At March 31, 2019, all debt and preferred equity investments were performing in accordance with the terms of the relevant investments, with the exception of one mezzanine loan which is in maturity default as discussed in subnote 5 of the Debt Investments table below. At December 31, 2018, all debt and preferred equity investments were performing in accordance with the terms of the relevant investments. At March 31, 2019, the Company's loan loss reserves of $1.8 million were attributable to one investment with an unpaid principal balance of $144.8 million that is being marketed for sale, is performing in accordance with its respective terms, and was not put on nonaccrual.

We have determined that we have one portfolio segment of financing receivables at March 31, 2019 and December 31, 2018 comprising commercial real estate which is primarily recorded in debt and preferred equity investments. Included in other assets is an additional amount of financing receivables totaling $89.6 million and $88.8 million at March 31, 2019 and December 31, 2018, respectively. No financing receivables were 90 days past due at March 31, 2019 and December 31, 2018 with the exception of a $28.4 million financing receivable which was put on nonaccrual in August 2018 as a result of interest default. The loan was evaluated in accordance with our loan review procedures and the Company concluded that the fair value of the collateral exceeded the carrying amount of the loan.

As of March 31, 2019, Management estimated the weighted average risk rating for our debt and preferred equity investments to be 1.3.

6. Investments in Unconsolidated Joint Ventures

We have investments in several real estate joint ventures with various partners. As of March 31, 2019, the book value of these investments was $3.1 billion, net of investments with negative book values totaling $79.7 million for which we have an implicit commitment to fund future capital needs.

Our net equity investment in these VIEs was $869.5 million and $808.3 million as of March 31, 2019 and December 31, 2018, respectively. Our maximum loss is limited to the amount of our equity investment in these VIEs. See the "Principles of Consolidation" section of Note 2, "Significant Accounting Policies". All other investments below are voting interest entities. As we do not control the joint ventures listed below, we account for them under the equity method of accounting.

(1) Ownership interest and economic interest represent the Company's interests in the joint venture as of March 31, 2019. Changes in ownership or economic interests 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 asset value of the property or properties on that date. Acquisition date and price are not adjusted for subsequent acquisitions or dispositions of interest.

(3) In January 2018, the partnership agreement for our investment was modified resulting in the Company no longer having a controlling interest in this investment. As a result the investment was deconsolidated as of January 1, 2018. We recorded our non-controlling interest at fair value resulting in a $49.3 million fair value adjustment in the consolidated statement of operations. This fair value was allocated to the assets and liabilities, including identified intangibles, of the joint venture.

(4) The acquisition 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) In March 2019, we, along with our joint venture partner, entered into an agreement to sell this property.

(6) 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.

(7) 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.

(8) In February 2019, we, together with our joint venture partner, closed on the sale of one property from the Stonehenge Portfolio. This sale is further described under Sale of Joint Venture Interest of Properties below. In May 2019, we closed on the sale of our interest in one additional property from the Stonehenge Portfolio.

(9) In October 2016, we sold a 49% interest in this property to an investment account managed by BlackRock, Inc. 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.

(10) The partners' ownership interest in the joint venture is based on their capital contributions, up to an aggregate maximum of 29.0%. As of March 31, 2019 the total of the two partners' ownership interests based on equity contributed was 28.17%.

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 March 31, 2019 and December 31, 2018, the carrying value for acquisition, development and construction arrangements were as follows (dollars in thousands):

Loan Type	March 31, 2019		December 31, 2018		Maturity Date
Mezzanine Loan(1)	44,824		44,357		February 2022
	$	44,824	$	44,357

(1) We have an option to convert our loan to an equity interest subject to certain conditions. We have determined that our option to convert the loan to equity is not a derivative financial instrument pursuant to GAAP. In May 2019, the Company purchased a majority and controlling interest in the underlying property.

Disposition of Joint Venture Interests or Properties

The following table summarizes the investments in unconsolidated joint ventures sold during the three months ended March 31, 2019:

Property	Ownership Interest	Disposition Date	Gross Asset Valuation (in thousands)(1)		Gain on Sale (in thousands)(2)

103 East 86th Street(3)	1.00%	February 2019	90,500		19

(1) Represents implied gross valuation for the joint venture or sales price of the property.

(2) Represents our share of the gain. Gain amounts do not include adjustments for expenses recorded in subsequent periods.

(3) Property was part of the Stonehenge Portfolio.

Joint Venture Mortgages and Other Loans Payable

We generally finance our joint ventures with non-recourse debt. In certain cases we may provide guarantees or master leases for tenant space, which terminate upon the satisfaction of specified circumstances or repayment of the underlying loans. The first mortgage notes and other loans payable collateralized by the respective joint venture properties and assignment of leases at March 31, 2019 and December 31, 2018, respectively, are as follows (dollars in thousands):

Master Repurchase Agreement

The Company entered into a Master Repurchase Agreement, or MRA, known as the 2017 MRA, which provides us with the ability to sell certain debt investments with a simultaneous agreement to repurchase the same at a certain date or on demand. We seek to mitigate risks associated with our repurchase agreement by managing the credit quality of our assets, early repayments, interest rate volatility, liquidity, and market value. The margin call provisions under our repurchase facility permit valuation adjustments based on capital markets activity, and are not limited to collateral-specific credit marks. To monitor credit risk associated with our debt investments, our asset management team regularly reviews our investment portfolio and is in contact with our borrowers in order to monitor the collateral and enforce our rights as necessary. The risk associated with potential margin calls is further mitigated by our ability to recollateralize the facility with additional assets from our portfolio of debt investments, our ability to satisfy margin calls with cash or cash equivalents and our access to additional liquidity through the 2017 credit facility, as defined below.

The 2017 MRA has a maximum facility capacity of $300.0 million. In April 2018, we increased the maximum facility capacity to $400.0 million. The facility bears interest on a floating rate basis at a spread to 30-day LIBOR based on the pledged collateral and advance rate and has an initial one year term, with twoone year extension options. In June 2018, we exercised a one year extension option. At March 31, 2019, the facility had a carrying value of $299.9 million, net of deferred financing costs.

9. Corporate Indebtedness

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 March 31, 2019, 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 twosix-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, 2019, 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) 150 basis points to 245 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.

At March 31, 2019, the applicable spread was 100 basis points for the revolving credit facility, 110 basis points for Term Loan A, and 165 basis points for Term Loan B. We are required to pay quarterly in arrears a 12.5 to 30 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to the senior unsecured long term indebtedness of the Company. As of March 31, 2019, the facility fee was 20 basis points.

As of March 31, 2019, we had $11.8 million of outstanding letters of credit, $790.0 million drawn under the revolving credit facility and $1.5 billion outstanding under the term loan facilities, with total undrawn capacity of $0.7 billion under the 2017 credit facility. At March 31, 2019 and December 31, 2018, the revolving credit facility had a carrying value of $782.7 million and $492.2 million, respectively, net of deferred financing costs. At March 31, 2019 and December 31, 2018, the term loan facilities had a carrying value of $1.5 billion and $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).

(5) In October 2017, the Company and the Operating Partnership as co-obligors issued an additional $100.0 million of 4.50% senior unsecured notes due December 2022. The notes were priced at 105.334%.

Restrictive Covenants

The terms of the 2017 credit facility 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 March 31, 2019 and December 31, 2018, 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. Interest payments may be deferred for a period of up to eight consecutive quarters if the Operating Partnership exercises its right to defer such payments. The Trust preferred securities are redeemable at the option of the Operating Partnership, in whole or in part, with no prepayment premium. We do not consolidate the Trust even though it is a variable interest entity as we are not the primary beneficiary. Because the Trust is not consolidated, we have recorded the debt on our consolidated balance sheets and the related payments are classified as interest expense.

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. Holliday and Mathias will lose the entire amount of their investment. The entities owned and controlled by Messrs. Holliday and Mathias paid $1.4 million and $1.0 million, respectively, which equal the fair market value of the interests acquired as of the date the investment agreements were entered into as determined by an independent third party appraisal that we obtained.

Other

We are entitled to receive fees for providing management, leasing, construction supervision and asset management services to certain of our joint ventures as further described in Note 6, "Investments in Unconsolidated Joint Ventures."

The Series G Preferred Units also provide the holder with the right to require the Operating Partnership to repurchase the Series G Preferred Units for cash before January 31, 2022.

(5) All of the outstanding units were redeemed at par for cash by the unitholder during the three months ended March 31, 2019.

(6) The holder of the Series O preferred unit is entitled to quarterly dividends in an amount calculated as (i) 1,350 multiplied by (ii) the current distribution per common unit of limited partnership in SL Green Operating Partnership. The holder has the right to require the Operating Partnership to repurchase the Series O unit for cash at a price that is determined based on the closing price of the Company's common stock at the time such right is exercised. The unit's liquidation preference is the fair market value of the unit at the time of a liquidation event.

(7) The annual dividend is subject to reduction upon the occurrence of certain circumstances. The minimum annual dividend is $0.75 per unit.

(8) Issued through a consolidated subsidiary. The units are convertible on a one-for-one basis, into the Series B Preferred Units of limited partnership interest, or the Subsidiary Series B Preferred Units. The Subsidiary Series B Preferred Units can be converted at any time, at the option of the unitholder, into a number of common stock equal to 6.71348 shares of common stock for each Subsidiary Series B Preferred Unit. As of March 31, 2019, no Subsidiary Series B Preferred Units have been issued.

Share Repurchase Program

In August 2016, our Board of Directors approved a share repurchase plan under which we can buy up to $1.0 billion of shares of our common stock. The Board of Directors has since authorized three separate $500.0 million increases to the size of the share repurchase program in the fourth quarter of 2017, second quarter of 2018, and fourth quarter of 2018, bringing the total program size to $2.5 billion.

At March 31, 2019, repurchases executed under the plan were as follows:

Period	Shares repurchased	Average price paid per share	Cumulative number of shares repurchased as part of the repurchase plan or programs
Year ended 2017	8,342,411	$101.64	8,342,411
Year ended 2018	9,744,911	$96.22	18,087,322
First quarter 2019	397,783	$86.07	18,485,105

Perpetual Preferred Stock

We have 9,200,000 shares of our 6.50% Series I Cumulative Redeemable Preferred Stock, or the Series I Preferred Stock, outstanding with a mandatory liquidation preference of $25.00 per share. The Series I Preferred stockholders receive annual dividends of $1.625 per share paid on a quarterly basis and dividends are cumulative, subject to certain provisions. We are entitled to redeem the Series I Preferred Stock at par for cash at our option. In August 2012, we received $221.9 million in net proceeds from the issuance of the Series I Preferred Stock, which were recorded net of underwriters' discount and issuance costs, and contributed the net proceeds to the Operating Partnership in exchange for 9,200,000 units of 6.50% Series I Cumulative Redeemable Preferred Units of limited partnership interest, or the Series I Preferred Units.

Dividend Reinvestment and Stock Purchase Plan ("DRSPP")

In February 2018, the Company filed a registration statement with the SEC for our dividend reinvestment and stock purchase plan, or DRSPP, which automatically became effective upon filing. The Company registered 3,500,000 shares of our common stock under the DRSPP. The DRSPP commenced on September 24, 2001.

The following table summarizes SL Green common stock issued, and proceeds received from dividend reinvestments and/or stock purchases under the DRSPP for the three months ended March 31, 2019 and 2018, respectively (dollars in thousands):

Earnings per Share

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

13. Partners' Capital of the Operating Partnership

The Company is the sole managing general partner of the Operating Partnership and at March 31, 2019 owned 83,272,202 general and limited partnership interests in the Operating Partnership and 9,200,000 Series I Preferred Units. Partnership interests in the Operating Partnership are denominated as “common units of limited partnership interest” (also referred to as “OP Units”) or “preferred units of limited partnership interest” (also referred to as “Preferred Units”). All references to OP Units and Preferred Units outstanding exclude such units held by the Company. A holder of an OP Unit may present such OP Unit to the Operating Partnership for redemption at any time (subject to restrictions agreed upon at the issuance of OP Units to particular holders that may restrict such right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, the Operating Partnership must redeem such OP Unit in exchange for the cash equal to the then value of a share of common stock of the Company, except that the Company may, at its election, in lieu of cash redemption, acquire such OP Unit for one share of common stock. Because the number of shares of common stock outstanding at all times equals the number of OP Units that the Company owns, one share of common stock is generally the economic equivalent of one OP Unit, and the quarterly distribution that may be paid to the holder of an OP Unit equals the quarterly dividend that may be paid to the holder of a share of common stock. Each series of Preferred Units makes a distribution that is set in accordance with an amendment to the partnership agreement of the Operating Partnership. Preferred Units may also be convertible into OP Units at the election of the holder thereof or the Company, subject to the terms of such Preferred Units.

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

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) 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 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 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 March 31, 2019, 4.5 million fungible units were available for issuance under the 2005 Plan after reserving for shares underlying outstanding restricted stock units, phantom stock units granted pursuant to our Non-Employee Directors' Deferral Program and LTIP Units.

Stock Options and Class O LTIP Units

Options are granted with an exercise price at the fair market value of the Company's common stock on the date of grant and, subject to employment, generally expire five or ten years from the date of grant, are not transferable other than on death, and generally vest in one 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 during the three months ended March 31, 2019 and the year ended December 31, 2018. There were no grants during the three months ended March 31, 2019.

Expected life	zero	3.5 years

All options were granted with strike prices ranging from $20.67 to $137.18. The remaining weighted average contractual life of the options outstanding was 3.2 years and the remaining average contractual life of the options exercisable was 3.2 years.

During the three months ended March 31, 2019, we recognized compensation expense for these options of $0.6 million. During the three months ended March 31, 2018, we recognized compensation expense for these options of $1.6 million.

As of March 31, 2019, there was $1.9 million of total unrecognized compensation cost related to unvested stock options, which is expected to be recognized over a weighted average period of 0.8 years.

Restricted Shares

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

A summary of the Company's restricted stock as of March 31, 2019 and December 31, 2018 and charges during the three months ended March 31, 2019 and the year ended December 31, 2018, are as follows:

	March 31, 2019			December 31, 2018
Balance at beginning of period	3,452,016			3,298,216
Granted	6,000			162,900
Canceled	(5,950		)	(9,100		)
Balance at end of period	3,452,066			3,452,016
Vested during the period	110,274			92,114
Compensation expense recorded	$	3,411,841		$	12,757,704
Total fair value of restricted stock granted during the period	$	474,480		$	13,440,503

The fair value of restricted stock that vested during the three months ended March 31, 2019 and the year ended December 31, 2018 was $11.8 million and $9.8 million, respectively. As of March 31, 2019 there was $19.4 million of total unrecognized compensation cost related to restricted stock, which is expected to be recognized over a weighted average period of 2.1 years.

We granted LTIP Units, which include bonus, time-based and performance-based awards, with a fair value of $41.6 million and $22.0 million as of March 31, 2019 and December 31, 2018, respectively. The grant date fair value of the LTIP Unit awards was calculated in accordance with ASC 718. A third party consultant determined the fair value of the LTIP Units to have a discount from our common stock price. The discount was calculated by considering the inherent uncertainty that the LTIP Units will reach parity with other common partnership units and the illiquidity due to transfer restrictions. As of March 31, 2019, there was $28.5 million of total unrecognized compensation expense related to the time-based and performance based awards, which is expected to be recognized over a weighted average period of 2.7 years.

Deferred Compensation Plan for Directors

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

During the three months ended March 31, 2019, 14,298 phantom stock units and 9,722 shares of common stock were issued to our board of directors. We recorded compensation expense of $1.9 million during the three months ended March 31, 2019 related to the Deferred Compensation Plan. We recorded compensation expense of $2.2 million during the three months ended March 31, 2018 related to the Deferred Compensation Plan.

As of March 31, 2019, there were 124,576 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 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 March 31, 2019, 120,085 shares of our common stock had been issued under the ESPP.

(2) Amount reclassified from accumulated other comprehensive income (loss) is included in equity in net (loss) income from unconsolidated joint ventures in the respective consolidated statements of operations.

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 impairment in real estate investments and debt and preferred equity investments, including intangibles 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 2018, the partnership agreement for our investment in 919 Third Avenue was modified resulting in the Company no longer having a controlling interest in this investment. As a result the investment was deconsolidated as of January 1, 2018. The Company recorded its non-controlling interest at fair value resulting in a $49.3 million fair value adjustment in the consolidated statement of operations. This fair value was determined using a third party valuation which primarily utilized cash flow projections that apply, among other things, estimated revenue and expense growth rates, discount rates and capitalization rates, as well as sales comparison approach, which utilizes comparable sales, listings and sales contracts. All of which are classified as Level 3 inputs.

Marketable securities classified as Level 1 are derived from quoted prices in active markets. The valuation technique used to measure the fair value of marketable securities classified as Level 2 were valued based on quoted market prices or model driven valuations using the significant inputs derived from or corroborated by observable market data. 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 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.

The following table provides the carrying value and fair value of these financial instruments as of March 31, 2019 and December 31, 2018 (in thousands):

	March 31, 2019				December 31, 2018
	Carrying Value (1)		Fair Value		Carrying Value (1)		Fair Value
Debt and preferred equity investments	$	2,272,241	(2)		$	2,099,393	(2)

(1) Amounts exclude net deferred financing costs.

(2) At March 31, 2019, debt and preferred equity investments had an estimated fair value ranging between $2.3 billion and $2.5 billion. At December 31, 2018, debt and preferred equity investments had an estimated fair value ranging between $2.1 billion and $2.3 billion.

Disclosure about fair value of financial instruments was based on pertinent information available to us as of March 31, 2019 and December 31, 2018. Although we are not aware of any factors that would significantly affect the reasonable fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date and current estimates of fair value may differ significantly from the amounts presented herein.

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 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 until the hedged item is recognized in earnings. Reported net income and equity may increase or decrease prospectively, depending on future levels of interest rates and other variables affecting the fair values of derivative instruments and hedged items, but will have no effect on cash flows. Currently, all of our designated derivative instruments are effective hedging instruments.

The following table summarizes the notional value at inception and fair value of our consolidated derivative financial instruments at March 31, 2019 based on Level 2 information. The notional value is an indication of the extent of our involvement in these instruments at that time, but does not represent exposure to credit, interest rate or market risks (dollars in thousands).

The Company has agreements with each of its derivative counterparties that contain a provision where if the Company either defaults or is capable of being declared in default on any of its indebtedness, then the Company could also be declared in default on its derivative obligations. As of March 31, 2019, the fair value of derivatives in a net liability position including accrued interest but excluding any adjustment for nonperformance risk related to these agreements was $15.7 million. As of March 31, 2019, the Company has not posted any collateral related to these agreements and was not in breach of any agreement provisions. If the Company had breached any of these provisions, it could have been required to settle its obligations under the agreements at their aggregate termination value of $16.2 million at March 31, 2019.

Gains and losses on terminated hedges are included in accumulated other comprehensive income, 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 income will be reclassified into earnings as an adjustment to interest expense in the same periods in which the hedged interest payments affect earnings. We estimate that $0.9 million of the current balance held in accumulated other comprehensive income will be reclassified into interest expense and $0.4 million of the portion related to our share of joint venture accumulated other comprehensive income will be reclassified into equity in net income from unconsolidated joint ventures within the next 12 months.

The following table presents the effect of our derivative financial instruments and our share of our joint ventures' derivative financial instruments that are designated and qualify as hedging instruments on the consolidated statements of operations for the three months ended March 31, 2019 and 2018, respectively (in thousands):

18. Rental Income

The Operating Partnership is the lessor and the sublessor to tenants under operating leases with expiration dates ranging from April 1, 2019 to 2064. The minimum rental amounts due under the leases are generally either subject to scheduled fixed increases or adjustments. The leases generally also require that the tenants reimburse us for increases in certain operating costs and real estate taxes above their base year costs. Approximate future minimum rents to be received over the next five years and thereafter for non-cancelable operating leases in effect at March 31, 2019 for the consolidated properties, including consolidated joint venture properties, and our share of unconsolidated joint venture properties, are as follows (in thousands):

	Consolidated Properties		Unconsolidated Properties

19. Commitments and Contingencies

Legal Proceedings

As of March 31, 2019, the Company and the Operating Partnership were not involved in any material litigation nor, to management's knowledge, was any material litigation threatened against us or our portfolio which if adversely determined could have a material adverse impact on us.

Our management believes that the properties are in compliance in all material respects with applicable Federal, state and local ordinances and regulations regarding environmental issues. Management is not aware of any environmental liability that it believes would have a materially adverse impact on our financial position, results of operations or cash flows. Management is unaware of any instances in which it would incur significant environmental cost if any of our properties were sold.

Ground Lease Arrangements

We are a tenant under ground leases for certain properties. The leases range in term from three to 95 years, with certain leases offering extension options which we assess against relevant economic factors to determine whether we are reasonably certain of exercising or not exercising the option. Lease payments associated with renewal periods that we are reasonably certain will be exercised, if any, are included in the measurement of the corresponding lease liability and right of use asset.

The following is a schedule of future minimum lease payments under financing leases and operating leases with initial terms in excess of one year as of March 31, 2019 (in thousands):

	Financing leases			Operating leases (1)
Remaining 2019	$	1,814		$	23,303
2020	2,619			31,437
2021	2,794			31,629
2022	2,794			29,472
2023	2,794			27,166
2024	2,819			27,183
Thereafter	814,283			648,905
Total minimum lease payments	$	829,917		$	819,095
Amount representing interest	(786,094		)
Amount discounted using incremental borrowing rate				(429,238		)
Lease liabilities	$	43,823		$	389,857

(1) As of March 31, 2019, the total minimum sublease rentals to be received in the future under non-cancelable subleases is $1.8 billion.

During the three months ended March 31, 2019 , we recognized $1.1 million of financing lease costs, of which $0.8 million represented interest and $0.3 million represented amortization of the right-of-use assets. These amounts are included in interest expense, net of interest income and depreciation and amortization in our consolidated statements of operations, respectively. During the three months ended March 31, 2019, we recognized $8.3 million of operating lease costs, which is calculated on a straight-line basis over the remaining lease terms. This amount is included in operating lease rent in our consolidated statements of operations. As of March 31, 2019, the weighted-average discount rate used to calculate the lease liabilities was 8.44%. As of March 31, 2019, the weighted-average remaining lease term was 67 years.

20. Segment Information

The Company has two reportable segments, real estate and debt and preferred equity investments. We evaluate real estate performance and allocate resources based on earnings contributions.

The primary sources of revenue are generated from tenant rents and escalations and reimbursement revenue. Real estate property operating expenses consist primarily of security, maintenance, utility costs, insurance, real estate taxes and ground rent expense (at certain applicable properties). See Note 5, "Debt and Preferred Equity Investments," for additional details on our debt and preferred equity investments.

Selected consolidated results of operations for the three months ended March 31, 2019 and 2018, and selected asset information as of March 31, 2019 and December 31, 2018, regarding our operating segments are as follows (in thousands):

Interest costs for the debt and preferred equity segment include actual costs incurred for borrowings on the 2017 MRA. Interest is imputed on the investments that do not collateralize the 2017 MRA using our weighted average corporate borrowing cost. We also allocate loan loss reserves, net of recoveries, and transaction related costs to the debt and preferred equity segment. We do not allocate marketing, general and administrative expenses to the debt and preferred equity segment since the use of personnel and resources is dependent on transaction volume between the two segments and varies period over period. In addition, we base performance on the individual segments prior to allocating marketing, general and administrative expenses. For the three months ended March 31, 2019, and 2018, marketing, general and administrative expenses totaled $26.0 million and $23.5 million respectively. All other expenses, except interest, relate entirely to the real estate assets.

There were no transactions between the above two segments.

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

Overview

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

The following discussion related to our consolidated financial statements should be read in conjunction with the financial statements appearing in this Quarterly Report on this Form 10-Q and in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2018.

As of March 31, 2019, we owned the following interests in properties in the New York metropolitan area, primarily in midtown Manhattan. Our investments located outside of Manhattan are referred to as the Suburban properties:

		Consolidated			Unconsolidated		Total

(1) The weighted average occupancy for commercial properties represents the total occupied square feet divided by total square footage at acquisition. The weighted average occupancy for residential properties represents the total occupied units divided by total available units.

(2) As of March 31, 2019, we owned a building at 315 West 33rd Street, also known as The Olivia, that was comprised of approximately 270,132 square feet (unaudited) of retail space and approximately 222,855 square feet (unaudited) of residential space. For the purpose of this report, we have included this building in the number of retail properties we own. However, we have included only the retail square footage in the retail approximate square footage, and have listed the balance of the square footage as residential square footage.

As of March 31, 2019, we also managed two office buildings owned by third parties encompassing approximately 2.1 million square feet (unaudited), and held debt and preferred equity investments with a book value of $2.3 billion, including $0.1 billion of debt and preferred equity investments and other financing receivables that are included in other balance sheet line items other than the Debt and Preferred Equity Investments line item.

55

Critical Accounting Policies

Refer to the 2018 Annual Report on Form 10-K of the Company and the Operating Partnership for a discussion of our critical accounting policies, which include investment in commercial real estate properties, investment in unconsolidated joint ventures, revenue recognition, reserve for possible credit losses and derivative instruments. During the three months ended March 31, 2019, there were no material changes to these policies, other than the adoption of the Accounting Standards Codification Topic 842, Leases, described in Note 2 - Significant Accounting Policies and Note 19 - Commitments and Contingencies to the unaudited consolidated financial statements in Part I, Item I of this Quarterly Report on Form 10-Q.

56

Reconciliation of Net Income to Same-Store Operating Income

We present Same-Store Operating Income because we believe 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 our 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. We use 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. This metric may be defined differently, and may not be comparable, to similarly named metrics used by other companies.

For properties owned since January 1, 2018 and still owned and operated at March 31, 2019, Same-Store Operating Income is determined as follows (in millions):

	Three months ended
	March 31,
(in millions)	2019			2018
Net income	$	52.8		$	113.8
Loss (gain) on sale of real estate, net	1.0			(23.5		)
Equity in net (gain) loss on sale of interest in unconsolidated joint venture/real estate	(17.2		)	6.4
Purchase price and other fair value adjustments	2.0			(49.3		)
Depreciation and amortization	68.3			69.4
Interest expense, net of interest income	50.5			47.9
Amortization of deferred financing costs	2.7			3.5
Operating income	160.1			168.2

Results of Operations

Comparison of the three months ended March 31, 2019 to the three months ended March 31, 2018

The following comparison for the three months ended March 31, 2019, or 2019, to the three months ended March 31, 2018, or 2018, makes reference to the effect of the following:

i. “Same-Store Properties,” which represents all operating properties owned by us at January 1, 2018 and still owned by us in the same manner at March 31, 2019 (Same-Store Properties totaled40 of our 49 consolidated operating properties),

ii. “Acquisition Properties,” which represents all properties or interests in properties acquired in 2019 and 2018 and all non-Same-Store Properties, including properties that are under development or redevelopment,

iii. "Disposed Properties" which represents all properties or interests in properties sold in 2019 and 2018, and

iv. “Other,” which represents properties where we sold an interest resulting in deconsolidation and corporate level items not allocable to specific properties, as well as the Service Corporation and eEmerge Inc.

Rental Revenue

Rental revenues decreased primarily as a result of Disposed Properties ($5.0 million), which included the sale of 635 Madison in the second quarter of 2018 ($1.5 million). The decrease was partially offset by increased revenue at our Same-Store properties ($4.7 million).

(5) Average starting office rent excluding new tenants replacing vacancies was $36.38 per rentable square feet for 12,700 rentable square feet. Average starting office rent for office space (leased and early renewals, excluding new tenants replacing vacancies) was $32.93 per rentable square feet for 31,025 rentable square feet.

Investment Income

For the three months ended March 31, 2019, investment income increased primarily as a result of an increase in the weighted average book balance of our debt and preferred equity investments. For the three months ended March 31, 2019, the weighted average debt and preferred equity investment balance outstanding and weighted average yield were $2.2 billion and 8.8%, respectively, compared to $2.0 billion and 9.2%, respectively, for the same period in 2018. As of March 31, 2019, the debt and preferred equity investments had a weighted average term to maturity of 1.8 years, excluding extension options.

Other Income

Other income decreased primarily due to lease termination income recognized in 2018 ($2.9 million), and promote income related to the sale of 1274 5th Avenue ($2.1 million), partially offset by a $4.1 million insurance settlement related to a previous tenant.

Property Operating Expenses

Property operating expenses decreased primarily due to the Disposed Properties ($2.5 million), partially offset by increased real estate taxes at our Same-Store Properties ($2.2 million).

Marketing, General and Administrative Expenses

Marketing, general and administrative expenses were $26.0 million for the three months ended March 31, 2019, or 5.9% of total combined revenues, including our share of joint venture revenues, and an annualized 55 basis points of total combined assets, including our share of joint venture assets for 2019 compared to $23.5 million for the three months ended March 31, 2018, or 5.3% of total revenues including our share of joint venture revenues, and 50 basis points of total assets including our share of joint venture assets for 2018. Marketing, general and administrative expenses for the three months ended March 31, 2019 includes $2.2 million of additional expense related to new accounting guidance for leasing costs, which requires the Company to expense certain internal costs that were previously capitalized.

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

Interest expense and amortization of deferred financing costs, net of interest income, increased primarily as a result of a higher weighted average balance and rate of the 2017 revolver ($6.8 million) and term loans ($2.5 million), partially offset by the extinguishment of debt at One Madison Avenue ($7.1 million) in the fourth quarter of 2018. The weighted average consolidated debt balance outstanding was $5.9 billion for the three months ended March 31, 2019, compared to $5.5 billion for the three months ended March 31, 2018. The consolidated weighted average interest rate was 4.04% for the three months ended March 31, 2019, as compared to 3.99% for the three months ended March 31, 2018.

Depreciation and Amortization

Depreciation and amortization decreased primarily as a result of the acceleration of amortization related to the redevelopment

60

of 609 5th Avenue in the first quarter of 2018 ($2.4 million), partially offset by 712 Madison Avenue, which is a newly acquired property that started depreciating in the fourth quarter of 2018 ($1.4 million).

Equity in Net (Loss) Income in Unconsolidated Joint Ventures

Equity in net (loss) income from unconsolidated joint ventures decreased primarily as a result of increased depreciation at 650 5th Avenue ($3.0 million) and 2 Herald Square ($1.7 million), as well as the repayment and redemption of certain debt and preferred equity investments accounted for under the equity method ($2.5 million).

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

During the three months ended March 31, 2019, we recognized a gain on sale related to our interests in 131-137 Spring Street ($17.7 million).

Purchase price and other fair value adjustments

In January 2018, the partnership agreement for our investment in 919 Third Avenue was modified resulting in our partner now having substantive participating rights in the venture and the Company no longer having a controlling interest in this investment. As a result the investment in this property was deconsolidated as of January 1, 2018. The Company recorded its non-controlling interest at fair value resulting in a $49.3 million fair value adjustment in the consolidated statement of operations. This fair value was allocated to the assets and liabilities, including identified intangibles of the property.

(Loss) gain on sale of real estate, net

During the three months ended March 31, 2018, we recognized a gain on sale related to our interest in 600 Lexington Avenue ($23.8 million).

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

(4) Borrowings under the 2017 credit facility;

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

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

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

The combined aggregate principal maturities of our property mortgages and other loans payable, corporate obligations and our share of joint venture debt, including as-of-right extension options, as of March 31, 2019 were as follows (in thousands):

	Remaining 2019		2020		2021		2022		2023		Thereafter		Total
Property mortgages and other loans	$	5,143	$	26,641	$	201,379	$	207,985	$	122,851	$	1,145,407	$	1,709,406

As of March 31, 2019, we had $173.7 million of consolidated cash on hand, inclusive of $29.4 million of marketable securities. We expect to generate positive cash flow from operations for the foreseeable future. We may seek to divest of properties or interests in properties 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

61

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 Flows

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

Cash, cash equivalents, and restricted cash were $295.7 million and $378.3 million at March 31, 2019 and 2018, respectively, representing a decrease of $82.6 million. The decrease was a result of the following changes in cash flows (in thousands):

	Three Months Ended March 31,
	2019			2018			Increase (Decrease)
Net cash provided by operating activities	$	62,313		$	94,546		$	(32,233	)
Net cash (used in) provided by investing activities	$	(291,843	)	$	456,002		$	(747,845	)
Net cash provided by (used in) financing activities	$	246,128		$	(422,309	)	$	668,437

Our principal source of operating cash flow is related to the leasing and operating of the properties in our portfolio. Our properties provide a relatively consistent stream of cash flow that provides us with resources to pay operating expenses, debt service and fund quarterly dividend and distribution requirements. Our debt and preferred equity investments and joint venture investments also provide a steady stream of operating cash flow to us.

Cash is used in investing activities to fund acquisitions, development or redevelopment projects and recurring and nonrecurring capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing and property management skills and invest in existing buildings that meet our investment criteria. During the three months ended March 31, 2019, when compared to the three months ended March 31, 2018, the change in investing cash flows was due to the following activities (in thousands):

Acquisitions of real estate property	$	1,276
Additions to land, buildings and improvements	12,107
Acquisition deposits and deferred purchase price	(1,890		)
Investments in unconsolidated joint ventures	(22,193		)
Distributions in excess of cumulative earnings from unconsolidated joint ventures	(119,030		)
Net proceeds from disposition of real estate/joint venture interest	(395,378		)
Other investments	20,631
Origination of debt and preferred equity investments	(200,606		)
Repayments or redemption of debt and preferred equity investments	(42,762		)
Decrease in net cash provided by investing activities	$	(747,845	)

Funds spent on capital expenditures, which are comprised of building and tenant improvements, decreased from $51.6 million for the three months ended March 31, 2018 to $39.5 million for the three months ended March 31, 2019. The decrease in capital expenditures relates primarily to lower costs incurred in connection with the redevelopment of properties.

We generally fund our investment activity through the sale of real estate, property-level financing, our credit facilities, our MRA facilities, senior unsecured notes, convertible or exchangeable securities, and construction loans. From time to time, the Company may issue common or preferred stock, or the Operating Partnership may issue common or preferred units of limited partnership interest.

62

During the three months ended March 31, 2019, when compared to the three months ended March 31, 2018, we used cash for the following financing activities (in thousands):

Proceeds from mortgages and other loans payable	$	10,757
Repayments of mortgages and other loans payable	8,279
Proceeds from revolving credit facility and senior unsecured notes	65,000
Repayments of revolving credit facility and senior unsecured notes	265,000
Proceeds from stock options exercised and DRSPP issuance	(724		)
Repurchase of common stock	348,436
Redemption of preferred units	(14,992		)
Redemption of OP units	(15,697		)
Distributions to noncontrolling interests in other partnerships	68
Contributions from noncontrolling interests in other partnerships	4
Distributions to noncontrolling interests in the Operating Partnership	198

Increase in net cash provided by financing activities	$	668,437

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 March 31, 2019, 83,272,202 shares of common stock and no shares of excess stock were issued and outstanding.

Share Repurchase Program

In August 2016, our Board of Directors approved a share repurchase plan under which we can repurchase up to $1.0 billion of shares of our common stock. The Board of Directors has since authorized three separate $500.0 million increases to the size of the share repurchase program in the fourth quarter of 2017, second quarter of 2018, and fourth quarter of 2018 bringing the total program size to $2.5 billion.

At March 31, 2019, repurchases executed under the plan were as follows:

Period	Shares repurchased	Average price paid per share	Cumulative number of shares repurchased as part of the repurchase plan or programs
Year ended 2017	8,342,411	$101.64	8,342,411
Year ended 2018	9,744,911	$96.22	18,087,322

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 2005 Plan. As of March 31, 2019, 4.5 million fungible units were available for issuance under the 2005 Plan after reserving for shares underlying outstanding restricted stock units, phantom stock units granted pursuant to our Non-Employee Directors' Deferral Program and LTIP Units.

Deferred Compensation Plan for Directors

During the three months ended March 31, 2019, 14,298 phantom stock units and 9,722 shares of common stock were issued to our board of directors. We recorded compensation expense of $1.9 million during the three months ended March 31, 2019 related to the Deferred Compensation Plan. We recorded compensation expense of $2.2 million during the three months ended March 31, 2018 related to the Deferred Compensation Plan.

As of March 31, 2019, there were 124,576 phantom stock units outstanding pursuant to our Non-Employee Director's Deferral Program.

Indebtedness

The table below summarizes our consolidated mortgages and other loans payable, 2017 credit facility, senior unsecured notes and trust preferred securities outstanding at March 31, 2019 and December 31, 2018, (amounts in thousands).

Debt Summary:	March 31, 2019			December 31, 2018

Effective Interest Rate for the Year:
Fixed rate	4.05		%	4.34		%
Variable rate	4.03		%	3.57		%
Effective interest rate	4.04		%	4.06		%

The variable rate debt shown above generally bears interest at an interest rate based on 30-day LIBOR (2.49% and 2.50% at March 31, 2019 and December 31, 2018, respectively). Our consolidated debt at March 31, 2019 had a weighted average term to maturity of 4.31 years.

64

Certain of our debt and equity investments and other investments, with a carrying value of $1.3 billion at March 31, 2019, are variable rate investments which mitigate our exposure to interest rate changes on our unhedged variable rate debt.

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 March 31, 2019, 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 twosix-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, 2019, 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) 150 basis points to 245 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.

At March 31, 2019, the applicable spread was 100 basis points for the revolving credit facility, 110 basis points for Term Loan A, and 165 basis points for Term Loan B. We are required to pay quarterly in arrears a 12.5 to 30 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to the senior unsecured long term indebtedness of the Company. As of March 31, 2019, the facility fee was 20 basis points.

As of March 31, 2019, we had $11.8 million of outstanding letters of credit, $790.0 million drawn under the revolving credit facility and $1.5 billion outstanding under the term loan facilities, with total undrawn capacity of $0.7 billion under the 2017 credit facility. At March 31, 2019 and December 31, 2018, the revolving credit facility had a carrying value of $782.7 million and $492.2 million, respectively, net of deferred financing costs. At March 31, 2019 and December 31, 2018, the term loan facilities had a carrying value of $1.5 billion and $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 2017 credit facility 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 March 31, 2019 and December 31, 2018, 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. Based on the debt outstanding as of March 31, 2019, a hypothetical 100 basis point increase in the floating rate interest rate curve would increase our consolidated annual interest cost, net of interest income from variable rate debt and preferred equity investments, by $10.2 million and would increase our share of joint venture annual interest cost by $14.0 million. At March 31, 2019, 58.4% of our $2.3 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 $3.5 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 March 31, 2019 bore interest based on a spread of LIBOR plus 18 basis points to LIBOR plus 340 basis points.

65

Contractual Obligations

Refer to our 2018 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 months ended March 31, 2019.

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 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.

Capital Expenditures

We estimate that for the remainder of the year ending December 31, 2019, we expect to incur $102.5 million of recurring capital expenditures and $49.1 million of development or redevelopment expenditures on existing consolidated properties, and our share of capital expenditures at our joint venture properties will be $318.7 million. 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 dividends to our stockholders based on the distributions we receive from our Operating Partnership primarily from property revenues net of operating expenses or, if necessary, from working capital.

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 to continue to pay regular quarterly dividends to our stockholders. Based on our current annual dividend rate of $3.40 per share, we would pay $283.1 million in dividends to our common stockholders on an annual basis. Before we pay any dividend, whether for Federal income tax purposes or otherwise, which would only be paid out of available cash to the extent permitted under the 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. Separate property and liability coverage may be purchased on a stand-alone basis for certain assets, such as the development of One Vanderbilt. Additionally, one of our captive insurance companies, Belmont Insurance Company, or Belmont, provides coverage for NBCR terrorist acts above a specified trigger. Belmont's retention is reinsured by our other captive insurance company, Ticonderoga Insurance Company ("Ticonderoga"). If Belmont or Ticonderoga are required to pay a claim under our insurance policies, we would ultimately record the loss to the extent of required payments. However, there is no assurance that in the future we will be able to procure coverage at a reasonable cost. Further, if we experience losses that are uninsured or that exceed policy limits, we could lose the capital invested in the damaged properties as well as the anticipated future cash flows from those properties. Additionally, our debt instruments contain customary covenants requiring us to maintain insurance and we could default under our debt instruments if the cost and/or availability of certain types of insurance make it impractical or impossible to comply with such covenants relating to insurance. Belmont and Ticonderoga provide coverage solely on properties owned by the Company or its affiliates.

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

Funds from Operations

FFO is a widely recognized non-GAAP financial measure of REIT performance. The Company computes FFO in accordance with standards established by 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 restated in December 2018, defines FFO as net income (loss) (computed in accordance with GAAP),

66

excluding gains (or losses) from sales of properties and real estate related impairment charges, plus real estate related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures.

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

FFO for the three months ended March 31, 2019 and 2018 are as follows (in thousands):

	Three Months Ended March 31,
	2019			2018
Net income attributable to SL Green common stockholders	$	43,792		$	101,766

Cash flows provided by (used in) financing activities	$	246,128		$	(422,309	)

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 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.

ITEM 4.    CONTROLS AND PROCEDURES

SL GREEN REALTY CORP.

Evaluation of Disclosure Controls and Procedures

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

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

Changes in Internal Control over Financial Reporting

There have been no significant changes in the Company's internal control over financial reporting during the quarter ended March 31, 2019 that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.
