EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended September 30, 2017 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; and references to "SL Green Operating Partnership, L.P.," the "Operating Partnership" or "SLGOP" mean SL Green Operating Partnership, L.P. and its consolidated subsidiaries. The terms "we," "our" and "us" mean the Company and all the entities owned or controlled by the Company, including the Operating Partnership.

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

As of September 30, 2017 the Company owns 95.55% of the outstanding general and limited partnership interest in the Operating Partnership. The Company also owns 9,200,000 Series I Preferred Units of the Operating Partnership. As of September 30, 2017 , noncontrolling investors held, in aggregate, a 4.45% 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.

1. Organization and Basis of Presentation

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

Substantially all of our assets are held by, and all of our operations are conducted through, the Operating Partnership. The Company is the sole managing general partner of the Operating Partnership. As of September 30, 2017 , noncontrolling investors held, in the aggregate, a 4.45% 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".

Reckson Associates Realty Corp., or Reckson, and Reckson Operating Partnership, L.P., or ROP, are wholly-owned subsidiaries of SL Green Realty Corp.

As of September 30, 2017 , we owned the following interests in properties in the New York Metropolitan area, primarily in midtown Manhattan. Our investments in the New York Metropolitan area also include investments in Brooklyn, Long Island, Westchester County, Connecticut and New Jersey, which are collectively known as the Suburban properties:

(2)

As of September 30, 2017 , 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.


(3)	Includes the properties at 16 Court Street in Brooklyn, New York, and 125 Chubb Avenue in Lyndhurst, New Jersey which are classified as held for sale at September 30, 2017. The sales closed in October 2017.

As of September 30, 2017 , we also managed an approximately 336,000 square foot (unaudited) office building owned by a third party and held debt and preferred equity investments with a book value of $2.2 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.

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. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for the fair presentation of the financial position of the Company and the Operating Partnership at September 30, 2017 and the results of operations for the periods presented have been included. The operating results for the period presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 . These financial statements should be read in conjunction with the financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2016 of the Company and the Operating Partnership.

The consolidated balance sheet at December 31, 2016 has been derived from the audited financial statements as of that date but do 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 variable interest entity, or VIE, in which we are considered the primary beneficiary. The primary beneficiary is the entity that has (i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE.

Investment in Commercial Real Estate Properties

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

(unaudited)

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

We allocate the purchase price of real estate to land and building (inclusive of tenant improvements) and, if determined to be material, intangibles, such as the value of above- and below-market leases and origination costs associated with the in-place leases. We depreciate the amount allocated to building (inclusive of tenant improvements) over their estimated useful lives, which generally range from three 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.

We recognized $4.6 million and $15.8 million of rental revenue for the three and nine months ended September 30, 2017 , and $0.2 million and $191.4 million of rental revenue for the three and nine months ended September 30, 2016 for the amortization of aggregate below-market 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. Included in rental revenue is zero and $172.4 million for the three and nine months ended September 30, 2016 , for the amortization of the below-market lease at 388-390 Greenwich Street as a result of the tenant exercising their option to purchase the property and entering into an agreement to accelerate the sale. For the three and nine months ended September 30, 2017 , we recognized as a reduction to interest expense the amortization of above-market rate mortgages of $0.0 million and $0.8 million , respectively. For the three and nine months ended September 30, 2016 , we recognized as a reduction to interest expense the amortization of the above-market rate mortgages assumed of $0.7 million and $2.0 million , respectively.

The following summarizes our identified intangible assets (acquired above-market leases and in-place leases) and intangible liabilities (acquired below-market leases) as of September 30, 2017 and December 31, 2016 (in thousands):



	September 30, 2017			December 31, 2016
Identified intangible assets (included in other assets):
Gross amount	$	474,493		$	651,099
Accumulated amortization	(398,047		)	(410,930		)
Net ⁽¹⁾	$	76,446		$	240,169
Identified intangible liabilities (included in deferred revenue):
Gross amount	$	639,511		$	655,930
Accumulated amortization	(474,365		)	(464,749		)
Net ⁽¹⁾	$	165,146		$	191,181


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

Fair Value Measurements

See Note 16, "Fair Value Measurements."

Investment in Marketable Securities

At acquisition, we designate a security as held-to-maturity, available-for-sale, or trading. As of September 30, 2017 , we did not have any securities designated as held-to-maturity or trading. We account for our available-for-sale securities at fair value pursuant to Accounting Standards Codification, or ASC, 820-10, with the net unrealized gains or losses reported as a component of accumulated other comprehensive income or loss. Any unrealized losses that are determined to be other-than-temporary are recognized in earnings up to their credit component.

September 30, 2017

(unaudited)

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

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



	September 30, 2017		December 31, 2016
Equity marketable securities	$	—	$	48,315
Commercial mortgage-backed securities	28,802		36,795
Total marketable securities available-for-sale	$	28,802	$	85,110

The cost basis of the commercial mortgage-backed securities was $27.5 million and $36.0 million at September 30, 2017 and December 31, 2016 , respectively. These securities mature at various times through 2049. We held no equity marketable securities as of September 30, 2017 . The cost basis of the equity marketable securities was $43.3 million at December 31, 2016 .

During the three and nine months ended September 30, 2017 , we disposed of marketable securities for aggregate net proceeds of $0.8 million and $55.2 million , respectively. During the three and nine months ended September 30, 2016 , we disposed of marketable securities for aggregate net proceeds of $1.7 million and $6.9 million , respectively.

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 September 30, 2017 .

Reserve for Possible Credit Losses

The expense for possible credit losses in connection with debt and preferred equity investments is the charge to earnings to increase the allowance for possible credit losses to the level that we estimate to be adequate, based on Level 3 data, considering delinquencies, loss experience and collateral quality. Other factors considered include geographic trends, product diversification, the size of the portfolio and current economic conditions. Based upon these factors, we establish a provision for possible credit loss on each individual investment. When it is probable that we will be unable to collect all amounts contractually due, the investment is considered impaired.

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the net 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. There were no loan reserves recorded during the three and nine months ended September 30, 2017 and 2016 .

Income Taxes

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

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

Pursuant to amendments to the Code that became effective January 1, 2001, we have elected, and may elect in the future, to treat certain of our existing or newly created corporate subsidiaries as taxable REIT subsidiaries, or TRSs. In general, TRSs may perform non-customary services for the tenants of the Company, hold assets that we cannot hold 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.

Notes to Consolidated Financial Statements (cont.)

September 30, 2017

(unaudited)

During the three and nine months ended September 30, 2017 , we recorded Federal, state and local tax provisions of $0.1 million and $2.8 million , respectively.

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

Use of Estimates

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

Concentrations of Credit Risk

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

We perform 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 primarily located in Manhattan. We also have properties located in Brooklyn, Long Island, Westchester County, Connecticut and New Jersey. The tenants located in our buildings operate in various industries. Other than two tenants, Credit Suisse Securities (USA), Inc. and Viacom International, Inc., who account for 8.8% and 6.7% of our share of annualized cash rent, no other tenant in our portfolio accounted for more than 5.0% of our share of annualized cash rent, including our share of joint venture annualized rent, at September 30, 2017 . For the three months ended September 30, 2017 , 8.9% , 6.3% , 6.2% , and 5.4% of our share of cash rent, including our share of joint venture annualized rent, was attributable to 1515 Broadway, 11 Madison Avenue, 1185 Avenue of the Americas, and 420 Lexington Avenue, respectively. Our share of annualized cash rent for all other 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 2017, the FASB issued Accounting Standards Update (ASU) No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. The amendments in the new standard will permit more flexibility in hedging interest rate risk for both variable rate and fixed rate financial instruments. The standard will also enhance the presentation of hedge results in the financial statements. The guidance is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. The Company has not yet adopted the guidance, and does not expect a material impact on the Company’s consolidated financial statements when the new standard is implemented.

In May 2017, the FASB issued Accounting Standards Update (ASU) No. 2017-09, Compensation - Stock Compensation (Topic 718), Scope of Modification Accounting. The guidance clarifies the changes to the terms or conditions of a share-based payment award that require an entity to apply modification accounting in Topic 718. The guidance is effective for fiscal years beginning after December 15, 2017 and early adoption is permitted. The Company has not yet adopted the guidance.

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

In January, 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The guidance clarifies the definition of a business and provides guidance to assist with determining whether transactions should be accounted for as acquisitions of assets or businesses.

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

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

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

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

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The guidance simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted the guidance effective January 1, 2017 and there was no material impact on the Company’s consolidated financial statements.

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

In February 2016, the FASB issued ASU 2016-02, Leases. The guidance requires lessees to recognize lease assets and lease liabilities for those leases classified as operating leases under the previous standard. Depending on the lease classification, lessees will recognize expense based on the effective interest method for finance leases or on a straight-line basis for operating leases. The accounting applied by a lessor is largely unchanged from that applied under the previous standard. One of the impacts on the Company will be the presentation and disclosure in the financial statements of non-lease components such as charges to tenants for a building’s operating expenses. The non-lease components will be presented separately from the lease components in both the Consolidated Statements of Operations and Consolidated Balance Sheets. Another impact is the measurement and presentation of ground leases under which the Company is lessee. The Company is required to record a liability for the obligation to make payments under the lease and an asset for the right to use the underlying asset during the lease term and will also apply the new expense recognition requirements given the lease classification. The Company is currently quantifying these impacts. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company anticipates adopting this guidance January 1, 2019 and will apply the modified retrospective approach.

In January 2016, the FASB issued ASU 2016-01 (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and to record changes in instruments-specific credit risk for financial liabilities

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

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

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

3. Property Acquisitions

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

4. Properties Held for Sale and Property Dispositions

Properties Held for Sale

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

As of September 30, 2017, 16 Court Street in Brooklyn, New York and 125 Chubb in Lyndhurst, New Jersey were held for sale. We closed on the sale of both properties in October 2017.

Property Dispositions

The following table summarizes the properties sold during the nine months ended September 30, 2017 :



Property	Disposition Date	Property Type	Approximate Square Feet	Sales Price ⁽¹⁾ (in millions)		Gain (loss) ⁽²⁾ (in millions)
885 Third Avenue ⁽³⁾	February 2016	Fee Interest	607,000	$	453.0	$	(8.8	)
520 White Plains Road	April 2017	Office	180,000	21.0		(14.6		)
102 Greene Street ⁽⁴⁾	April 2017	Retail	9,200	43.5		4.9
680-750 Washington Boulevard	July 2017	Office	325,000	97.0		(44.2		)


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


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


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


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

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


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


(5)	Carrying value is net of the following amounts that were sold or syndicated, which are included in other assets and other liabilities on the consolidated balance sheets as a result of the transfers not meeting the conditions for sale accounting: (a) $1.2 million , (b) $12.0 million , (c) $14.6 million , (d) $14.1 million , (e) $5.1 million , and (f) $21.2 million

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


(4)	This investment was redeemed in May 2017.


(5)	This investment was redeemed in April 2017.

At September 30, 2017 and December 31, 2016 , all debt and preferred equity investments were performing in accordance with the terms of the relevant investments, with the exception of a mortgage and junior mortgage participation purchased in maturity default in May 2017 and April 2017 discussed in subnote 3 of the Debt Investments table above and a junior mortgage participation acquired in September 2014, which was acquired for zero and has a carrying value of zero , as further discussed in subnote 4 of the Debt Investments table above.

We have determined that we have one portfolio segment of financing receivables at September 30, 2017 and 2016 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 $65.6 million and $99.5 million at September 30, 2017 and December 31, 2016 , respectively. No financing receivables were 90 days past due at September 30, 2017 .

6. Investments in Unconsolidated Joint Ventures

We have investments in several real estate joint ventures with various partners. As of September 30, 2017 , 800 Third Avenue, 21 East 66th Street, 605 West 42 ^nd Street, 333 East 22nd Street, One Vanderbilt, and certain properties within the Stonehenge Portfolio are VIEs in which we are not the primary beneficiary. Our net equity investment in these VIEs was $ 598.7 million as of September 30, 2017 . As of December 31, 2016 , 650 Fifth Avenue, 800 Third Avenue, 21 East 66th Street, 605 West 42 ^nd Street, 333 East 22nd Street, and certain properties within the Stonehenge Portfolio were VIEs in which we were not the primary beneficiary. Our net equity investment in these VIEs was $220.1 million as of December 31, 2016 . Our maximum loss is limited to the amount of our equity investment in these VIEs. 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 September 30, 2017 . Changes in ownership or economic interests, if any, within the current year are disclosed in the notes below.


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


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


(4)	The purchase price represents only the purchase of the 1552 Broadway interest which comprised approximately 13,045 square feet. The joint venture also owns a long-term leasehold interest in the retail space and certain other spaces at 1560 Broadway, which is adjacent to 1552 Broadway.


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

(6)

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


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


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

(9)

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


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

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

(11)

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

Acquisition, Development and Construction Arrangements

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



Loan Type	September 30, 2017		December 31, 2016		Maturity Date
Mezzanine Loan and Preferred Equity ⁽¹⁾	$	100,000	$	100,000	March 2018

Mezzanine Loan ⁽³⁾	25,854		24,542		July 2036
	$	170,735	$	170,164


(1)	These loans were extended in February 2017.


(2)	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.


(3)	The Company has the ability to convert this loan into an equity position starting in 2021 and the borrower is able to force this conversion in 2024.

Sale of Joint Venture Interests or Properties

The following table summarizes the investments in unconsolidated joint ventures sold during the nine months ended September 30, 2017 :



Property	Ownership Interest	Disposition Date	Type of Sale	Gross Asset Valuation (in thousands) ⁽¹⁾		Gain on Sale (in thousands) ⁽²⁾
Stonehenge Portfolio (partial)	Various	March 2017	Ownership Interest	$	300,000	$	871
102 Greene Street	10.00%	September 2017	Ownership Interest	$	43,500	$	283


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


(2)	Represents the Company's share of the gain.

In May 2017, our investment in a joint venture that owned two mezzanine notes secured by interests in the entity that owns 76 11th Avenue was repaid after the joint venture received repayment of the underlying loans.

In May 2017, we recognized a gain of $13.0 million related to the sale in May 2014 of our ownership interest in 747 Madison Avenue. The sale did not meet the criteria for sale accounting at that time and, therefore, remained on our consolidated financial statements. The sale criteria was met in the second quarter of 2017 resulting in recognition of the deferred gain on the sale.

Joint Venture Mortgages and Other Loans Payable

We generally finance our joint ventures with non-recourse debt. In certain cases we have provided 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 September 30, 2017 and December 31, 2016 , respectively, are as follows (amounts in thousands):

In connection with the acquisition of a commercial real estate property, the Operating Partnership issued $4.0 million , 3.75% Series J Preferred Units of limited partnership interest, or the Series J Preferred Units, with a mandatory liquidation preference of $1,000 per unit. The Series J Preferred Units are accounted for as debt because they can be redeemed in cash by the Operating Partnership on the earlier of (i) the date of the sale of the property or (ii) April 30, 2051 or at the option of the unitholders as provided for in the related agreement.


(6)	In February 2016, we closed on the sale of 885 Third Avenue. The sale did not meet the criteria for sale accounting at that time.

In April 2017, the criteria for deconsolidation were met, and the development is shown within investments in unconsolidated joint ventures. See Note 6, "Investments in Unconsolidated Joint Ventures".

Federal Home Loan Bank of New York Facility

The Company’s wholly-owned subsidiary, Belmont Insurance Company, or Belmont, a New York licensed captive insurance company, was a member of the Federal Home Loan Bank of New York, or FHLBNY. In January 2017, all funds borrowed from the FHLBNY were repaid and Belmont's membership was terminated in February 2017.

Master Repurchase Agreements

The Company has entered into two Master Repurchase Agreements, or MRAs, known as the 2016 MRA and 2017 MRA, which provide 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 facilities 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 2012 credit facility, as defined below.

In June 2017, we entered into the 2017 MRA, with a maximum facility capacity of $300.0 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 two one year extension options. At September 30, 2017 , the facility had a carrying value of $(1.1) million , representing deferred financing costs presented within other liabilities.

In July 2016, we entered into a restated 2016 MRA, with a maximum facility capacity of $300.0 million. The facility bears interest ranging from 225 and 400 basis points over 30-day LIBOR depending on the pledged collateral and has an initial two -year term, with a one year extension option. Since December 6, 2015, we have been required to pay monthly in arrears a 25 basis point fee on the excess of $150.0 million over the average daily balance during the period when the average daily balance is less than $150.0 million . At September 30, 2017 , the facility had a carrying value of $182.8 million , net of deferred financing costs.

2012 Credit Facility

In August 2016, we entered into an amendment to the credit facility that was originally entered into by the Company in November 2012, referred to as the 2012 credit facility. As of September 30, 2017 , the 2012 credit facility, as amended, consisted of a $1.6 billion revolving credit facility and a $1.2 billion term loan, with a maturity date of March 29, 2019 and June 30, 2019, respectively. The revolving credit facility has an as-of-right extension to March 29, 2020. We also have an option, subject to customary conditions, to increase the capacity under the revolving credit facility to $3.0 billion at any time prior to the maturity date for the revolving credit facility without the consent of existing lenders, by obtaining additional commitments from our existing lenders and other financial institutions.

As of September 30, 2017 , the 2012 credit facility bore interest at a spread over LIBOR ranging from (i) 87.5 basis points to 155 basis points for loans under the revolving credit facility and (ii) 95 basis points to 190 basis points for loans under the term loan facility, in each case based on the credit rating assigned to the senior unsecured long term indebtedness of ROP.

At September 30, 2017 , the applicable spread was 125 basis points for the revolving credit facility and 140 basis points for the term loan facility. At September 30, 2017 , the effective interest rate, including the effect of interest rate swaps, was 2.49% for the revolving credit facility and 2.49% for the term loan facility. 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 ROP. As of September 30, 2017 , the facility fee was 25 basis points.

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

The Company, the Operating Partnership and ROP are all borrowers jointly and severally obligated under the 2012 credit facility. None of our other subsidiaries are obligors under the 2012 credit facility.

The 2012 credit facility includes certain restrictions and covenants (see Restrictive Covenants below).

In October 2017, the Company, the Operating Partnership and ROP, as co-obligors issued an additional $100.0 million of the 4.50% senior unsecured bonds due December 2022. The additional notes priced at 105.334% plus accrued interest from June 1, 2017, with a yield to maturity of 3.298% .

In October 2017, the Company issued $500.0 million of senior unsecured notes which will mature in October 2022 and bear interest at a fixed rate of 3.25% .

Restrictive Covenants

The terms of the 2012 credit facility, as amended, and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, our ability to pay dividends, make certain types of investments, incur additional indebtedness, incur liens and enter into negative pledge agreements and dispose of assets, and which require compliance with financial ratios relating to the maximum ratio of total indebtedness to total asset value, a minimum ratio of EBITDA to fixed charges, a maximum ratio of secured indebtedness to total asset value and a maximum ratio of unsecured indebtedness to unencumbered asset value. The dividend restriction referred to above provides that, we will not during any time when a default is continuing, make distributions with respect to common stock or other equity interests, except to enable the Company to continue to qualify as a REIT for Federal income tax purposes. As of September 30, 2017 and 2016 , we were in compliance with all such covenants.

Junior Subordinated Deferrable Interest Debentures

In June 2005, the Company and the Operating Partnership issued $100.0 million in unsecured trust preferred securities through a newly formed trust, SL Green Capital Trust I, or the Trust, which is a wholly-owned subsidiary of the Operating Partnership. The securities mature in 2035 and bear interest at a floating rate of 125 basis points over the three-month LIBOR. The effective weighted average interest rate for the quarter ended September 30, 2017 was 2.52% . Interest payments may be deferred for a period of up to eight 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.

Cleaning/ Security/ Messenger and Restoration Services

Alliance Building Services, or Alliance, and its affiliates are partially owned by Gary Green, a son of Stephen L. Green, the chairman of SL Green's board of directors, and provide services to certain properties owned by us. Alliance’s affiliates include First Quality Maintenance, L.P., or First Quality, Classic Security LLC, Bright Star Couriers LLC and Onyx Restoration Works, and provide cleaning, extermination, security, messenger, and restoration services, respectively. In addition, First Quality has the non-exclusive opportunity to provide cleaning and related services to individual tenants at our properties on a basis separately negotiated with any tenant seeking such additional services. The Service Corporation has entered into an arrangement with Alliance whereby it will receive a profit participation above a certain threshold for services provided by Alliance to certain tenants at certain buildings above the base services specified in their lease agreements.

Income earned from profit participation, which is included in other income on the consolidated statements of operations, was $1.0 million and $3.0 million for the three and nine months ended September 30, 2017 , respectively, and was $0.8 million and $2.6 million for the three and nine months ended September 30, 2016 , respectively.

We also recorded expenses for these services, inclusive of capitalized expenses, of $5.7 million and $16.0 million for the three and nine months ended September 30, 2017 , respectively, for these services (excluding services provided directly to tenants), and $5.3 million and $16.1 million for the three and nine months ended September 30, 2016 , respectively.

Management Fees

S.L. Green Management Corp., a consolidated entity, receives property management fees from an entity in which Stephen L. Green owns an interest. We received management fees from this entity of $0.1 million and $0.4 million for the three and nine months ended September 30, 2017 , respectively, and $0.1 million and $0.3 million for the three and nine months ended September 30, 2016 , respectively.

One Vanderbilt Investment

In December 2016, we entered into agreements with entities owned and controlled by Marc Holliday and 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.

Fifty percent of these interests were purchased on December 31, 2016 and the remaining fifty percent will be purchased on December 31, 2017. The entities owned and controlled by Messrs. Holliday and Mathias will pay $1.4 million and $1.0 million , respectively, which equals 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.

13. Partners' Capital of the Operating Partnership

The Company is the sole general partner of the Operating Partnership and at September 30, 2017 owned 97,445,509 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.

Limited Partner Units

As of September 30, 2017 , limited partners other than SL Green owned 4.45% , or 4,541,765 common units, of the Operating Partnership.

Preferred Units

Preferred units not owned by SL Green are further described in Note 11, “Noncontrolling Interests on the Company’s Consolidated Financial Statements - Preferred Units of Limited Partnership Interest in the Operating Partnership.”

14. Share-based Compensation

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

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. The 2005 Plan authorizes the issuance of stock options, stock appreciation rights, unrestricted and restricted stock, phantom shares, dividend equivalent rights, cash-based awards and other equity-based awards. Subject to adjustments upon certain corporate transactions or events, awards with respect to up to a maximum of 27,030,000 fungible units may be granted under the 2005 Plan. Currently, different types of awards count against the limit on the number of fungible units differently, with (1) full-value awards (i.e., those that deliver the full value of the award upon vesting, such as restricted stock) granted after the effective date of the Fourth Amendment 2005 Plan counting as 3.74 Fungible Units per share subject to such awards, (2) stock options, stock appreciation rights and other awards that do not deliver full value and expire five years from the date of grant counting as 0.73 fungible units per share subject to such awards, and (3) all other awards (e.g., ten -year stock options) counting as 1.0 fungible units per share subject to such awards. Awards granted under the 2005 Plan prior to the approval of the fourth amendment and restatement in June 2016 continue to count against the fungible unit limit based on the ratios that were in effect at the time such awards were granted, which may be different than the current ratios. As a result, depending on the types of awards issued, the 2005 Plan may result in the issuance of more or less than 27,030,000 shares. If a stock option or other award granted under the 2005 Plan expires or terminates, the common stock subject to any portion of the award that expires or terminates without having been exercised or paid, as the case may be, will again become available for the issuance of additional awards. Shares of SL Green's common stock distributed under the 2005 Plan may be treasury shares or authorized but unissued shares. Currently, unless the 2005 Plan has been previously terminated by the Company's board of directors, new awards may be granted under the 2005 Plan until June 2, 2026, which is the tenth anniversary of the date that the 2005 Plan was most recently approved by the Company's stockholders. As of September 30, 2017 , 8.7 million fungible units were available for issuance under the 2005 Plan after reserving for shares underlying outstanding restricted stock units, phantom stock units granted pursuant to our Non-Employee Directors' Deferral Program and LTIP Units, including, among others, outstanding LTIP Units issued under our 2014 Outperformance Plan.

Options are granted under the plan with an exercise price at the fair market value of the Company's common stock on the date of grant and, subject to employment, generally expire five 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 nine months ended September 30, 2017 and the year ended December 31, 2016 .



	September 30, 2017		December 31, 2016
Dividend yield	2.50	%	2.37	%
Expected life	4.4 years		3.7 years
Risk-free interest rate	1.73	%	1.57	%
Expected stock price volatility	28.21	%	26.76	%

All options were granted with strike prices ranging from $20.67 to $128.82 . The remaining weighted average contractual life of the options outstanding was 3.6 years and the remaining average contractual life of the options exercisable was 2.8 years.

During the three and nine months ended September 30, 2017 , we recognized compensation expense for these options of $2.0 million and $5.9 million , respectively. During the three and nine months ended September 30, 2016 , we recognized compensation expense for these options of $2.5 million and $6.4 million , respectively.

As of September 30, 2017 , there was $10.6 million of total unrecognized compensation cost related to unvested stock options, which is expected to be recognized over a weighted average period of 1.7 years.

Stock-based Compensation

Effective January 1, 1999, the Company implemented a deferred compensation plan, or the Deferred Plan, where shares issued under the Deferred Plan were granted to certain employees, including certain of 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 September 30, 2017 and December 31, 2016 and charges during the nine months ended September 30, 2017 and the year ended December 31, 2016 , are as follows:



	September 30, 2017		December 31, 2016
Balance at beginning of period	3,202,031		3,137,881
Granted	300		98,800

Compensation expense recorded	$	7,277,054	$	7,153,966
Weighted average fair value of restricted stock granted during the period	$	30,813	$	10,650,077

The fair value of restricted stock that vested during the nine months ended September 30, 2017 and the year ended December 31, 2016 was $8.4 million and $7.6 million , respectively. As of September 30, 2017 there was $13.7 million of total unrecognized compensation cost related to restricted stock, which is expected to be recognized over a weighted average period of 1.7 years .

For the three and nine months ended September 30, 2017 , $1.4 million and $5.0 million , respectively, was capitalized to assets associated with compensation expense related to our long-term compensation plans, restricted stock and stock options. For the three and nine months ended September 30, 2016 , $1.5 million and $4.4 million , respectively, was capitalized to assets associated with compensation expense related to our long-term compensation plans, restricted stock and stock options.

We have granted LTIP Units, which include bonus, time-based and performance based awards, with a fair value of $20.5 million and $34.9 million as of September 30, 2017 and December 31, 2016 , 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 SL Green's common stock price. The discount was calculated by considering the inherent uncertainty that the LTIP Units will reach parity with other common partnership units and the illiquidity due to transfer restrictions. As of September 30, 2017 , there was $7.1 million of total unrecognized compensation expense related to the time-based and performance based awards, which is expected to be recognized over a weighted average period of 1.2 years .

During the three and nine months ended September 30, 2017 , we recorded compensation expense related to bonus, time-based and performance based awards of $2.5 million and $15.1 million , respectively. During the three and nine months ended September 30, 2016 , we recorded compensation expense related to bonus, time-based and performance based awards of $2.3 million and $15.1 million , respectively.

2014 Outperformance Plan

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

The cost of the 2014 Outperformance Plan ( $29.2 million , subject to forfeitures), based on the portion of the 2014 Outperformance Plan granted as of September 30, 2017 , will be amortized into earnings through the final vesting period. We recorded compensation expense of $1.9 million and $8.2 million for the three and nine months ended September 30, 2017 , respectively, related to the 2014 Outperformance Plan. We recorded compensation expense of $1.8 million and $6.6 million for the three and nine months ended September 30, 2016 , respectively, related to the 2014 Outperformance Plan.

Deferred Compensation Plan for Directors

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

During the nine months ended September 30, 2017 , 11,510 phantom stock units and 9,171 shares of common stock were issued to our board of directors. We recorded compensation expense of $0.1 million and $2.2 million during the three and nine months ended September 30, 2017 , respectively, related to the Deferred Compensation Plan. We recorded compensation expense of $0.1 million and $1.9 million during the three and nine months ended September 30, 2016 , respectively, related to the Deferred Compensation Plan.

As of September 30, 2017 , there were 98,637 phantom stock units outstanding pursuant to our Non-Employee Director's Deferral Program.

Employee Stock Purchase Plan

In 2007, the Company's board of directors adopted the 2008 Employee Stock Purchase Plan, or ESPP, to encourage our employees to increase their efforts to make our business more successful by providing equity-based incentives to eligible employees. The ESPP is intended to qualify as an "employee stock purchase plan" under Section 423 of the Code, and has been adopted by the board to enable our eligible employees to purchase the Company's shares of common stock through payroll deductions. The ESPP became effective on January 1, 2008 with a maximum of 500,000 shares of the common stock available for issuance, subject to adjustment upon a merger, reorganization, stock split or other similar corporate change. The Company filed a registration statement on Form S-8 with the SEC with respect to the ESPP. The common stock is offered for purchase through a series of successive offering periods. Each offering period will be three months in duration and will begin on the first day of each calendar quarter, with the first offering period having commenced on January 1, 2008. The ESPP provides for eligible employees to purchase the common stock at a purchase price equal to 85% of the lesser of (1) the market value of the common stock on the first day of the offering period or (2) the market value of the common stock on the last day of the offering period. The ESPP was approved by our stockholders at our 2008 annual meeting of stockholders. As of September 30, 2017 , 101,882 shares of SL Green's common stock had been issued under the ESPP.

(2)	Amount reclassified from accumulated other comprehensive income (loss) is included in equity in net 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.

The following tables set forth the assets and liabilities that we measure at fair value on a recurring and non-recurring basis by their levels in the fair value hierarchy at September 30, 2017 and December 31, 2016 (in thousands):

We determine other than temporary 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.

As of September 30, 2017, we held notes receivable totaling $250.0 million , which were purchased at par, and were in maturity default at the time of acquisition. In August 2017, the Company determined that it was probable that the loans would not be repaid in full and therefore, the loans were put on non-accrual status. The Company has initiated proceedings to foreclose on the property, and expects to take control of the property unless the buyer is able to repay the principal and interest, including default interest and fees, on the notes receivable in full prior to the completion of the foreclosure process. We believe the collateral value is sufficient to recover the carrying amounts of the notes receivable.

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

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

The financial assets and liabilities that are not measured at fair value on our consolidated balance sheets include cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, debt and preferred equity investments, mortgages and other loans payable and other secured and unsecured debt. The carrying amount of cash and cash equivalents, restricted cash, accounts receivable, and accounts payable and accrued expenses reported in our consolidated balance sheets approximates fair value due to the short term 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.

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 sheets 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. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. Reported net income and equity may increase or decrease prospectively, depending on future levels of interest rates and other variables affecting the fair values of derivative instruments and hedged items, but will have no effect on cash flows. Currently, all of our designated derivative instruments are effective hedging instruments.

The following table summarizes the notional value at inception and fair value of our consolidated derivative financial instruments at September 30, 2017 based on Level 2 information. The notional value is an indication of the extent of our involvement in these instruments at that time, but does not represent exposure to credit, interest rate or market risks (amounts in thousands).



	Notional Value		Strike Rate		Effective Date	Expiration Date	Balance Sheet Location	Fair Value

During both the three and nine months ended September 30, 2017 , we recorded a loss on the changes in the fair value of $0.1 million , which is included in interest expense on the consolidated statements of operations. During the three and nine months ended September 30, 2016 , we recorded a $0.1 million loss and a $0.5 million gain, respectively, on the changes in the fair value, which is included in interest expense on the consolidated statements of operations.

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 September 30, 2017 , 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 zero . As of September 30, 2017 , 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 zero at September 30, 2017 .

Gains and losses on terminated hedges are included in accumulated other comprehensive loss, and are recognized into earnings over the term of the related mortgage obligation. Over time, the realized and unrealized gains and losses held in accumulated other comprehensive loss will be reclassified into earnings as an adjustment to interest expense in the same periods in which the hedged interest payments affect earnings. We estimate that $0.8 million of the current balance held in accumulated other comprehensive loss will be reclassified into interest expense and $0.3 million of the portion related to our share of joint venture accumulated other comprehensive loss will be reclassified into equity in net income from unconsolidated joint ventures within the next 12 months.

19. Segment Information

The Company is a REIT with in-house capabilities in commercial and residential property management, acquisitions and dispositions, financing, development and redevelopment, construction and leasing in the New York Metropolitan area, and has two reportable segments, real estate and debt and preferred equity investments. We evaluate real estate performance and allocate resources based on earnings contribution to income from continuing operations.

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 and nine months ended September 30, 2017 and 2016 , and selected asset information as of September 30, 2017 and December 31, 2016 , regarding our operating segments are as follows (in thousands):

Income from continuing operations represents total revenues less total expenses for the real estate segment and total investment income less allocated interest expense for the debt and preferred equity segment. Interest costs for the debt and preferred equity segment includes actual costs incurred for borrowings on the 2016 MRA and 2017 MRA. Interest is imputed on the investments that do not collateralize the 2016 MRA or 2017 MRA using our 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 and nine months ended September 30, 2017 , marketing, general and administrative expenses totaled $24.0 million , and $72.4 million respectively. For the three and nine months ended September 30, 2016 , marketing, general and administrative expenses totaled $25.5 million and $74.0 million , respectively. All other expenses, except interest, relate entirely to the real estate assets.

There were no transactions between the above two segments.

Reconciliation of Net Income to Same-Store Operating Income

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

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

Rental, Escalation and Reimbursement Revenues

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

Escalation and reimbursement revenue decreased primarily as a result of Disposed Properties ($2.5 million) and lower recoveries at our Same-Store properties ($5.8 million).

The following table presents a summary of the commenced leasing activity for the three months ended September 30, 2017 in our Manhattan and Suburban portfolio:

Investment Income

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

Other Income

Other income increased primarily as a result of construction management and other fees earned from the One Vanderbilt venture ($0.5 million) in 2017.

Property Operating Expenses

Property operating expenses decreased primarily due to the effect of the partial sale and deconsolidation of 11 Madison Avenue ($3.7 million) in the third quarter of 2016, and the partial sale of 400 East 57th Street ($1.6 million) in the fourth quarter of 2016, offset by increased real estate taxes at our Same-Store Properties ($2.9 million).

Table of Contents

Transaction Related Costs

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

Marketing, General and Administrative Expenses

Marketing, general and administrative expenses for the three months ended September 30, 2017 were $24.0 million , or 5.1% of total combined revenues, including our share of joint venture revenues, and an annualized 51 basis points of total combined assets, including our share of joint venture assets compared to $25.5 million , or 5.2% of total revenues including our share of joint venture revenues, and 55 basis points of total assets including our share of joint venture assets for 2016.

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

Interest expense and amortization of deferred financing costs, net of interest income, decreased primarily as a result of the Disposed Properties ($10.7 million) which included the deconsolidation of 11 Madison in the third quarter of 2016 ($6.4 million), partially offset by a higher weighted average balance of the 2012 revolving credit facility ($2.1 million), and a higher weighted average balance of the 2012 term loan facility ($1.6 million). The weighted average consolidated debt balance outstanding was $6.7 billion for the three months ended September 30, 2017 compared to $7.2 billion for the three months ended September 30, 2016 . The consolidated weighted average interest rate was 3.98% for the three months ended September 30, 2017 as compared to 4.00% for the three months ended September 30, 2016 .

Depreciation and Amortization

Depreciation and amortization decreased primarily as a result of the Disposed Properties ($11.0 million), the acquisition of 110 Greene Street ($5.6 million) and starting the redevelopment of 5-7 Dey Street, 183 & 187 Broadway in 2017 ($5.1 million).

Equity in Net Income in Unconsolidated Joint Venture

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

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

During the three months ended September 30, 2017 , we recognized a gain on sale related to our interest in 102 Greene Street ($0.3 million).

Rental, Escalation and Reimbursement Revenues

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

Table of Contents

Escalation and reimbursement revenue decreased primarily as a result of Disposed Properties ($8.0 million) and lower recoveries at our Same-Store properties ($7.5 million).

Investment Income

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

Other Income

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

Table of Contents

Property Operating Expenses

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

Transaction Related Costs

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

Marketing, General and Administrative Expenses

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

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

Interest expense and amortization of deferred financing costs, net of interest income, decreased primarily as a result of the Disposed Properties ($64.5 million). The weighted average consolidated debt balance outstanding was $6.6 billion for the nine months ended September 30, 2017 compared to $9.1 billion for the nine months ended September 30, 2016 . The consolidated weighted average interest rate was 4.02% for the nine months ended September 30, 2017 as compared to 3.79% for the nine months ended September 30, 2016 .

Depreciation and Amortization

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

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

Equity in Net Income in Unconsolidated Joint Venture

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

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

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

Gain (loss) on sale of real estate, net

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

Depreciable Real Estate Reserves

During the nine months ended September 30, 2017 , we recorded a $85.3 million charge related to 125 Chubb Avenue in Lyndhurst, NJ, Stamford Towers and 520 White Plains Road in Tarrytown, NY. During the nine months ended September 30, 2016 , we recognized depreciable real estate reserves related to 500 West Putnam ($10.4 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, repurchases or repayments of outstanding indebtedness (which may include exchangeable debt) and for debt and preferred equity investments will include:


(1)	Cash flow from operations;


(2)	Cash on hand;


(3)	Borrowings under the 2012 credit facility;


(4)	Other forms of secured or unsecured financing;


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


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

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 September 30, 2017 are as follows (in thousands):

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

As of September 30, 2017 , we had $270.3 million of consolidated cash on hand, inclusive of $28.8 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 of liquidity, if we are able to access them, along with potential refinancing opportunities for secured 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 and cash equivalents were $241.5 million and $405.9 million at September 30, 2017 and 2016 , respectively, representing a decrease of $164.4 million . The decrease was a result of the following changes in cash flows (in thousands):

	Nine Months Ended September 30,
	2017			2016			Increase (Decrease)
Net cash provided by operating activities	$	416,621		$	508,792		$	(92,171	)
Net cash (used in) provided by investing activities	$	(101,041	)	$	2,405,173		$	(2,506,214	)
Net cash used in financing activities	$	(353,534	)	$	(2,763,468	)	$	2,409,934

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 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 nine months ended September 30, 2017 , when compared to the nine months ended September 30, 2016 , we used cash primarily for the following investing activities (in thousands):

Funds spent on capital expenditures, which comprise building and tenant improvements, decreased from $269.2 million for the nine months ended September 30, 2016 to $251.2 million for the nine months ended September 30, 2017 , relating primarily to decreased 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 2012 credit facility, our MRA facilities, senior unsecured notes, convertible or exchangeable securities, construction loans and from time to time, Company issued common or preferred stock, or the Operating Partnership may issue common or preferred units of limited partnership interest.

The variable rate debt shown above generally bears interest at an interest rate based on 30-day LIBOR ( 1.23% and 0.77% at September 30, 2017 and December 31, 2016 , respectively). Our consolidated debt at September 30, 2017 had a weighted average term to maturity of 4.72 years.

Table of Contents

Certain of our debt and equity investments and other investments, with a carrying value of $1.2 billion at September 30, 2017 , are variable rate investments which mitigate our exposure to interest rate changes on our unhedged variable rate debt.

2012 Credit Facility

Restrictive Covenants

Interest Rate Risk

We are exposed to changes in interest rates primarily from our variable rate debt. Our exposure to interest rate fluctuations are managed through either the use of interest rate derivative instruments and/or through our variable rate debt and preferred equity investments. A hypothetical 100 basis point increase in interest rates along the entire interest rate curve for 2017 would increase our consolidated annual interest cost, net of interest income from variable rate debt and preferred equity investments, by $1.0 million and would increase our share of joint venture annual interest cost by $16.6 million . At September 30, 2017 , 59.9% of our $2.0 billion debt and preferred equity portfolio is indexed to LIBOR.

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

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

Contractual Obligations

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

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.

Table of Contents

Capital Expenditures

We estimate that for the remainder of the year ending December 31, 2017, we expect to incur $66.9 million of recurring capital expenditures and $14.6 million of development or redevelopment expenditures, net of loan reserves, (including tenant improvements and leasing commissions) on existing consolidated properties, and our share of capital expenditures at our joint venture properties, net of loan reserves, will be $109.5 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 $3.10 per share, we would pay $316.2 million in dividends to SL Green's 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 2012 credit facility and senior unsecured notes, we must first meet both our operating requirements and scheduled debt service on our mortgages and loans payable.

Insurance

We maintain “all-risk” property and rental value coverage (including coverage regarding the perils of flood, earthquake and terrorism, excluding nuclear, biological, chemical, and radiological terrorism ("NBCR")), within three property insurance programs and liability insurance. Management believes the policy specifications and insured limits are appropriate given the relative risk of loss, the cost of the coverage, and industry practice. Separate property and liability coverage may be purchased on a stand-alone basis for certain assets, such as the development of One Vanderbilt.

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

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

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

Table of Contents

commercially reasonable rates, we may incur substantially higher insurance premiums or our ability to finance our properties and expand our portfolio may be adversely impacted.

Furthermore, with respect to certain of our properties, including properties held by joint ventures, or subject to triple net leases, insurance coverage is obtained by a third-party and we do not control the coverage. While we may have agreements with such third parties to maintain adequate coverage and we monitor these policies, such coverage ultimately may not be maintained or adequately cover our risk of loss. We may have less protection than with respect to the properties where we obtain coverage directly. Although we consider our insurance coverage to be appropriate, in the event of a major catastrophe, we may not have sufficient coverage to replace certain properties.

Funds from Operations

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

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 extraordinary items, it provides a performance measure that, when compared year over year, reflects the impact to operations from trends in occupancy rates, rental rates, operating costs, and interest costs, providing perspective not immediately apparent from net income. FFO does not represent cash generated from operating activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Company’s financial performance or to cash flow from operating activities (determined in accordance with GAAP) as a measure of the Company’s liquidity, nor is it indicative of funds available to fund the Company’s cash needs, including our ability to make cash distributions.

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

Inflation

Substantially all of our office leases provide for separate real estate tax and operating expense escalations as well as operating expense recoveries based on increases in the Consumer Price Index 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 September 30, 2017 that has materially affected, or is reasonably likely to materially affect, its internal control over financial reporting.
