EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the period ended June 30, 2018 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 June 30, 2018 the Company owns 94.80% 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 June 30, 2018 , noncontrolling investors held, in aggregate, a 5.20% 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 June 30, 2018 , noncontrolling investors held, in the aggregate, a 5.20% 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 June 30, 2018 , we owned the following interests in properties in the New York metropolitan area, primarily in midtown Manhattan. Our investments located outside of Manhattan are referred to as the Suburban properties:

(3)

As of June 30, 2018 , 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.


(4)	Includes the properties at 1-6 International Drive in Rye Brook, New York which are classified as held for sale at June 30, 2018 .

As of June 30, 2018 , 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 $2.4 billion , including $0.2 billion of debt and preferred equity investments and other financing receivables that are included in balance sheet line items other than the Debt and Preferred Equity Investments line item.

Partnership Agreement

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

Basis of Quarterly Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements. 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 June 30, 2018 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, 2018 .

(unaudited)

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, 2017 of the Company and the Operating Partnership.

The consolidated balance sheet at December 31, 2017 has been derived from the audited financial statements as of that date but does not include all the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

Subsequent Events

In August 2018, the Operating Partnership issued $350.0 million of senior unsecured notes, with the Company and ROP as guarantors. The notes bear interest at a floating rate, reset quarterly, equal to three-month LIBOR plus 98 basis points. The notes will mature in August 2021 and can be redeemed at par beginning in August 2019.

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

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.

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 impairment when a property has been classified as held for sale. Real estate assets held for sale are valued at the lower of their carrying value or fair value less costs to sell.

We recognized $1.8 million and $4.2 million of rental revenue for the three and six months ended June 30, 2018 and $6.4 million and $11.2 million for the three and six months ended June 30, 2017 , respectively, for the amortization of aggregate below-market leases in excess of above-market leases and a reduction in lease origination costs, resulting from the allocation of the purchase price of the applicable properties. For the three and six months ended June 30, 2018 we recognized as a reduction to interest expense the amortization of above-market rate mortgages of $0.0 million and $0.0 million , respectively. For the three and six months ended June 30, 2017 we recognized as a reduction to interest expense the amortization of above-market rate mortgages of $0.7 million and $1.3 million , respectively.

Fair Value Measurements

See Note 16, "Fair Value Measurements."

Investment in Marketable Securities

At acquisition, we designate a debt security as held-to-maturity, available-for-sale, or trading. As of June 30, 2018 , we did not have any debt securities designated as held-to-maturity or trading. We account for our available-for-sale debt 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.

The Company adopted ASU 2016-01 effective January 1, 2018 which required entities to measure investments in equity securities at fair value and recognize any changes in fair value in net income. Upon adoption we did not hold investments in equity securities and therefore did not record a cumulative-effect adjustment. We did not hold investments in equity securities as of June 30, 2018 .

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

At June 30, 2018 and December 31, 2017 , we held the following marketable securities (in thousands):



	June 30, 2018		December 31, 2017
Commercial mortgage-backed securities	$	28,570	$	28,579
Total marketable securities available-for-sale	$	28,570	$	28,579

The cost basis of the commercial mortgage-backed securities was $27.5 million at both June 30, 2018 and December 31, 2017 . These securities mature at various times through 2035. We held no equity marketable securities as of June 30, 2018 and December 31, 2017 .

During the three and six months ended June 30, 2018 , we did not dispose of any marketable securities. During the three months ended June 30, 2017 , we did not dispose of any marketable securities. During the six months ended June 30, 2017 , we disposed of marketable securities for aggregate net proceeds of $54.4 million and realized a gain of $3.3 million , which is included in gain on sale of investment in marketable securities on the consolidated statements of operations.

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 June 30, 2018 .

Reserve for Possible Credit Losses

The reserve 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 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 six months ended June 30, 2018 and 2017 .

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

Income Taxes

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

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

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.

During the three and six months ended June 30, 2018 , we recorded Federal, state and local tax provisions of $1.1 million and $1.6 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.

On December 22, 2017, the Tax Cuts and Jobs Act (the ‘‘Tax Act’’) was signed into law and makes substantial changes to the Code. Many of the provisions of the Tax Act will require guidance through the issuance of Treasury regulations in order to assess their effect. The Tax Act has not had a material impact on our financial statements.

Use of Estimates

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

Concentrations of Credit Risk

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

We perform ongoing credit evaluations of our tenants and require most tenants to provide security deposits or letters of credit. Though these security deposits and letters of credit are insufficient to meet the total value of a tenant's lease obligation, they are a measure of good faith and a source of funds to offset the economic costs associated with lost revenue and the costs associated with re-tenanting a space. The properties in our real estate portfolio are located in the New York metropolitan area. The tenants located in our buildings operate in various industries. Other than one tenant, Credit Suisse Securities (USA), Inc., who accounts for 8.2% of our share of annualized cash rent, no other tenant in our portfolio accounted for more than 5.0% of our share of annualized cash rent, including our share of joint venture annualized rent, at June 30, 2018 . For the three months ended June 30, 2018 , 7.3% , 7.2% , 6.4% , 5.8% and 5.7% of our annualized cash rent was attributable to 11 Madison Avenue, 1185 Avenue of the Americas, 420 Lexington Avenue, 1515 Broadway, and One Madison Avenue respectively. Annualized cash rent for all other consolidated properties was below 5.0% .

Reclassification

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

Accounting Standards Updates

In June 2018, the FASB issued Accounting Standard Update (ASU) No. 2018-07, Compensation - Stock Compensation (Topic 718), Improvements to Nonemployee Share-Based Payment Accounting. This amendment provides additional guidance related to share-based payment transactions for acquiring goods or services from nonemployees. The guidance will be effective for the Company for fiscal years beginning after December 15, 2018, including the interim periods within that fiscal year. The Company has not yet adopted this new guidance and does not expect it to have a material impact on the Company’s consolidated financial statements when the new standard is implemented.

In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments- Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. These amendments provide additional guidance related to equity securities without a readily determinable fair value, forward contracts and options purchased on those equity securities and fair value option liabilities. The guidance will be effective for the Company in the interim period beginning after June 15, 2018. The Company has not yet adopted this new guidance and does not expect it to have a material impact on the Company’s consolidated financial statements when the new standard is implemented.

In August 2017, the FASB issued 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. 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 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 Company adopted the guidance on January 1, 2018 and it had no impact on the Company's consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. The guidance requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash. As a result, entities will no longer present transfers between these items on the statement of cash flows. The Company adopted the guidance on January 1, 2018 and has included the changes in restricted cash when reconciling the beginning-of-period and end-of-period total amounts on the statement of cash flows.

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 15, 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 February 2016, the FASB issued ASU No. 2016-02, Leases, and in July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases and ASU No. 2018-11, Leases (Topic 842): Targeted Improvements. This 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, inclusive of the effect of a practical expedient offered in ASU No. 2018-11 that allows lessors to not separate non-lease components from the related lease components under certain conditions, which the Company expects most of its leases to qualify for and to adopt, is largely unchanged from that applied under the previous standard. However, the Company will apply this guidance to the 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. This guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The Company expects to adopt 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 through earnings, to record changes in instrument-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income, use the exit price notion when measuring an instrument’s fair value for disclosure and to separately present financial assets and liabilities by measurement category and form of instrument on the balance sheet or in the notes to the financial statements. The Company adopted the guidance effective January 1, 2018, and it had no impact 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. The Company adopted this guidance on January 1, 2018. Since the Company’s revenue is related to leasing activities, the adoption of this guidance did 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 did 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.

In February 2017, the FASB issued ASU No. 2017-05 to clarify the scope of asset derecognition guidance in Subtopic 610-20, which also provided 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 adopted this guidance on January 1, 2018, and applied the modified retrospective approach. The Company elected to adopt the practical expedient under ASC 606, Revenue from Contracts with Customers, which allows an entity to apply the guidance only to contracts with non-customers that are open based on ASU 360-20, Real Estate Sales, (i.e. failed sales) as of the adoption date. The Company had one open contract in 2017 with a non-customer that was evaluated under ASC 610-20. The Company entered into an agreement to sell a portion of their interest in an entity that held a controlling interest in the property at 1515 Broadway. Upon execution of the agreement in 2017, the transaction was evaluated under ASC 360-20, Real Estate Sales, and did not meet the criteria for sale accounting. Upon adoption of ASC 606, this contract met the criteria for sale accounting under ASC 610-20. Through the sale, the Company no longer retains a controlling interest, as defined in ASC 810, Consolidation, and the impact of this adjustment is a gain of $0.6 billion from the sale of the partial interest and related step-up in basis to fair value of the non-controlling interest retained. This was recorded in the first quarter of 2018 as an adjustment to beginning retained earnings.

3. Property Acquisitions

The following table summarizes the properties acquired during the six months ended June 30, 2018 :



Property	Acquisition Date	Property Type	Approximate Square Feet	Acquisition Price (in millions)
2 Herald Square ⁽¹⁾	May 2018	Leasehold Interest	369,000	$	266.0

(1)

In May 2018, SL Green was the successful bidder for the leasehold interest in 2 Herald Square, at the foreclosure of the asset. In April and May 2017, the Company had purchased, at par, loans in maturity default, which were secured by the leasehold interest in 2 Herald Square. 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 believed that the fair value of the leasehold exceeded the carrying amount of the loans. In May 2018, the Company was the successful bidder at the foreclosure of the asset. We recorded the assets acquired and liabilities assumed at fair value. This resulted in the recognition of a fair value adjustment of $11.1 million , which is reflected in the Company's consolidated statement of operations within purchase price and other fair value adjustments. See Note 16, "Fair Value Measurements."

In May 2018, we entered into an agreement to sell a partial interest in 2 Herald Square resulting in the leasehold interest being classified as held for sale as of June 30, 2018 . See Note 4, "Property Dispositions."

4. Properties Held for Sale and Property Dispositions

(1)	Ownership interest and economic interest represent the Company's interests in the joint venture as of June 30, 2018 . Changes in ownership or economic interests within the current year are disclosed in the notes below.


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

(3)

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


(4)	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.


(5)	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.


(6)	In July 2018, the Company closed on the sale of substantially all of its interest in 724 Fifth Avenue to its joint venture partner.


(7)	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.

(8)

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.


(9)	In February and March 2018, the Company, together with its joint venture partner, closed on the sale of two properties from the Stonehenge Portfolio. These sales are further described under Sale of Joint Venture Interest of Properties below.

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.


(11)	The partners have committed aggregate equity 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 June 30, 2018 the total of the two partners' ownership interests based on equity contributed was 13.39% .

(12)

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. The loan was repaid in August 2018.

(13)

In November 2017, the Company sold a 30 % interest in 1515 Broadway to affiliates of Allianz Real Estate. The sale did not meet the criteria for sale accounting and as a result the property was accounted for under the profit sharing method at December 31, 2017. The Company achieved sale accounting upon adoption of ASC 610-20 in January 2018 and recorded a $0.6 billion gain from the sale of the partial interest and related step-up in basis to fair value of the retained non-controlling interest as an adjustment to beginning retained earnings based on the application of the modified retrospective adoption approach. The Company closed on the sale of an additional 13% interest in the property to Allianz in February 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.

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 2017 credit facility, as defined below.

In June 2017, we entered into the 2017 MRA, with a maximum facility capacity of $300.0 million . In April 2018, we increased the maximum facility capacity to $400.0 million . The facility bears interest on a floating rate basis at a spread to 30-day LIBOR based on the pledged collateral and advance rate and has an initial one year term, with two one year extension options.

2017 Credit Facility

In November 2017, we entered into an amendment to the credit facility, referred to as the 2017 credit facility, that was originally entered into by the Company in November 2012, or the 2012 credit facility. As of June 30, 2018 , the 2017 credit facility consisted of a $1.5 billion revolving credit facility, a $1.3 billion term loan (or "Term Loan A"), and a $200.0 million term loan (or "Term Loan B") with maturity dates of March 31, 2022, March 31, 2023, and November 21, 2024, respectively. The revolving credit facility has two six -month as-of-right extension options to March 31, 2023. We also have an option, subject to customary conditions, to increase the capacity of the credit facility to $4.5 billion at any time prior to the maturity dates for the revolving credit facility and term loans without the consent of existing lenders, by obtaining additional commitments from our existing lenders and other financial institutions.

As of June 30, 2018 , the 2017 credit facility bore interest at a spread over 30-day LIBOR ranging from (i) 82.5 basis points to 155 basis points for loans under the revolving credit facility, (ii) 90 basis points to 175 basis points for loans under Term Loan A, and (iii) 150 basis points to 245 basis points for loans under Term Loan B, in each case based on the credit rating assigned to the senior unsecured long term indebtedness of the Company.

At June 30, 2018 , the applicable spread was 100 basis points for the revolving credit facility, 110 basis points for Term Loan A, and 165 basis points for Term Loan B. We are required to pay quarterly in arrears a 12.5 to 30 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to the senior unsecured long term indebtedness of the Company. As of June 30, 2018 , the facility fee was 20 basis points.

As of June 30, 2018 , we had $11.8 million of outstanding letters of credit, $360.0 million drawn under the revolving credit facility and $1.5 billion outstanding under the term loan facilities, with total undrawn capacity of $1.1 billion under the 2017 credit facility. At June 30, 2018 and December 31, 2017 , the revolving credit facility had a carrying value of $351.3 million and $30.3 million , respectively, net of deferred financing costs. At June 30, 2018 and December 31, 2017 , the term loan facilities had a carrying value of $1.5 billion and $1.5 billion , respectively, net of deferred financing costs.

Restrictive Covenants

The terms of the 2017 credit facility and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, our ability to pay dividends, make certain types of investments, incur additional indebtedness, incur liens and enter into negative pledge agreements and dispose of assets, and which require compliance with financial ratios relating to the maximum ratio of total indebtedness to total asset value, a minimum ratio of EBITDA to fixed charges, a maximum ratio of secured indebtedness to total asset value and a maximum ratio of unsecured indebtedness to unencumbered asset value. The dividend restriction referred to above provides that, we will not during any time when a default is continuing, make distributions with respect to common stock or other equity interests, except to enable the Company to continue to qualify as a REIT for Federal income tax purposes. As of June 30, 2018 and December 31, 2017 , we were in compliance with all such covenants.

Junior Subordinated Deferrable Interest Debentures

In June 2005, the Company and the Operating Partnership issued $100.0 million in unsecured trust preferred securities through a newly formed trust, SL Green Capital Trust I, or the Trust, which is a wholly-owned subsidiary of the Operating Partnership. The securities mature in 2035 and bear interest at a floating rate of 125 basis points over the three-month LIBOR. Interest payments may be deferred for a period of up to eight consecutive quarters if the Operating Partnership exercises its right to defer such payments. The Trust preferred securities are redeemable at the option of the Operating Partnership, in whole or in part, with no prepayment premium. We do not consolidate the Trust even though it is a variable interest entity as we are not the primary beneficiary. Because the Trust is not consolidated, we have recorded the debt on our consolidated balance sheets and the related payments are classified as interest expense.

One Vanderbilt Investment

In December 2016, we entered into agreements with entities owned and controlled by 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. The entities owned and controlled by Messrs. Holliday and Mathias paid $1.4 million and $1.0 million , respectively, which equal the fair market value of the interests acquired as of the date the investment agreements were entered into as determined by an independent third party appraisal that we obtained.

13. Partners' Capital of the Operating Partnership

The Company is the sole general partner of the Operating Partnership and at June 30, 2018 owned 85,725,135 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 June 30, 2018 , limited partners other than SL Green owned 5.20% , or 4,699,872 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) counting as 3.74 Fungible Units per share subject to such awards, (2) stock options, stock appreciation rights and other awards that do not deliver full value and expire five years from the date of grant counting as 0.73 fungible units per share subject to such awards, and (3) all other awards (e.g., ten -year stock options) counting as 1.0 fungible units per share subject to such awards. Awards granted under the 2005 Plan prior to the approval of the fourth amendment and restatement in June 2016 continue to count against the fungible unit limit based on the ratios that were in effect at the time such awards were granted, which may be different than the current ratios. As a result, depending on the types of awards issued, the 2005 Plan may result in the issuance of more or less than 27,030,000 shares. If a stock option or other award granted under the 2005 Plan expires or terminates, the common stock subject to any portion of the award that expires or terminates without having been exercised or paid, as the case may be, will again become available for the issuance of additional awards. Shares of our common stock distributed under the 2005 Plan may be treasury shares or authorized but unissued shares. Currently, unless the 2005 Plan has been previously terminated by the Company's board of directors, new awards may be granted under the 2005 Plan until June 2, 2026, which is the tenth anniversary of the date that the 2005 Plan was most recently approved by the Company's stockholders. As of June 30, 2018 , 7.4 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.

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 six months ended June 30, 2018 and the year ended December 31, 2017 .



	June 30, 2018		December 31, 2017
Dividend yield	2.85	%	2.51	%
Expected life	3.5 years		4.4 years
Risk-free interest rate	2.48	%	1.73	%

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

During the three and six months ended June 30, 2018 , we recognized compensation expense for these options of $1.6 million and $3.2 million , respectively. During the three and six months ended June 30, 2017 , we recognized compensation expense for these options of $1.9 million and $3.9 million , respectively.

As of June 30, 2018 , there was $4.9 million of total unrecognized compensation cost related to unvested stock options, which is expected to be recognized over a weighted average period of 1.3 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 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 June 30, 2018 and December 31, 2017 and charges during the six months ended June 30, 2018 and the year ended December 31, 2017 , are as follows:



	June 30, 2018			December 31, 2017

Compensation expense recorded	$	6,251,350		$	9,809,749
Total fair value of restricted stock granted during the period	$	163,831		$	9,905,986

The fair value of restricted stock that vested during the six months ended June 30, 2018 and the year ended December 31, 2017 was $9.8 million and $9.4 million , respectively. As of June 30, 2018 there was $15.2 million of total unrecognized compensation cost related to restricted stock, which is expected to be recognized over a weighted average period of 1.8 years .

For the three and six months ended June 30, 2018 , $1.6 million and $3.2 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 six months ended June 30, 2017 $2.0 million and $3.6 million , respectively, was capitalized to assets associated with compensation expense related to our long-term compensation plans, restricted stock and stock options.

We granted LTIP Units, which include bonus, time-based and performance based awards, with a fair value of $20.6 million and $20.5 million as of June 30, 2018 and December 31, 2017 , respectively. The grant date fair value of the LTIP Unit awards was calculated in accordance with ASC 718. A third party consultant determined the fair value of the LTIP Units to have a discount

from our common stock price. The discount was calculated by considering the inherent uncertainty that the LTIP Units will reach parity with other common partnership units and the illiquidity due to transfer restrictions. As of June 30, 2018 , there was $7.5 million of total unrecognized compensation expense related to the time-based and performance based awards, which is expected to be recognized over a weighted average period of 1.1 years .

During the three and six months ended June 30, 2018 , we recorded compensation expense related to bonus, time-based and performance based awards of $2.3 million and $9.1 million , respectively. During the three and six months ended June 30, 2017 we recorded compensation expense related to bonus, time-based and performance based awards of $2.6 million and $12.6 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 could 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 were subject to performance based vesting based on the Company’s absolute total return to stockholders and one-third of the LTIP Units were subject to performance based vesting based on relative total return to stockholders compared to the constituents of the MSCI REIT Index. LTIP Units earned under the 2014 Outperformance Plan were to 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 were not entitled to distributions with respect to LTIP Units granted under the 2014 Outperformance Plan unless and until they are earned. If LTIP Units were earned, each participant would have been 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 were to be paid currently with respect to all earned LTIP Units, whether vested or unvested.

Based on our performance, none of the LTIP Units granted under the 2014 Outperformance Plan were earned pursuant to the terms of the 2014 Outperformance Plan, and all units issued were forfeited in 2017.

The cost of the 2014 Outperformance Plan ( $27.9 million , subject to forfeitures), based on the portion of the 2014 Outperformance Plan granted prior to termination, was amortized into earnings through December 31, 2017 . We recorded no compensation expense for the three and six months ended June 30, 2018 related to the 2014 Outperformance Plan. We recorded compensation expense of $4.3 million and $6.3 million for the three and six months ended June 30, 2017 , 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 our common stock on the first business day of the respective quarter. Each participating non-employee director is also credited with dividend equivalents or phantom stock units based on the dividend rate for each quarter, which are either paid in cash currently or credited to the director’s account as additional phantom stock units.

During the six months ended June 30, 2018 , 11,502 phantom stock units and 9,332 shares of common stock were issued to our board of directors. We recorded compensation expense of $0.1 million and $2.1 million during the three and six months ended June 30, 2018 , respectively, related to the Deferred Compensation Plan. We recorded compensation expense of $0.2 million and $2.1 million during the three and six months ended June 30, 2017 , respectively, related to the Deferred Compensation Plan.

As of June 30, 2018 , there were 111,356 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 June 30, 2018 , 110,045 shares of our common stock had been issued under the ESPP.

(2)	Amount reclassified from accumulated other comprehensive income (loss) is included in equity in net 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 June 30, 2018 and December 31, 2017 (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.

In May 2018, the Company was the successful bidder at the foreclosure of 2 Herald Square, at which time the Company's $250.5 million outstanding principal balance and $7.7 million accrued interest balance receivables were credited to our equity investment in the property. We recorded the assets acquired and liabilities assumed at fair value. This resulted in the recognition of a fair value adjustment of $11.1 million , which is reflected on the Company's consolidated statement of operations within purchase price and other fair value adjustments. This fair value was determined by utilizing our successful bid at the foreclosure of the asset, the agreement to sell a partial interest in the property, and cash flow projections that apply, among other things, estimated revenue and expense growth rates, discount rates and capitalization rates, as well as a sales comparison approach, which utilizes comparable sales, listings and sales contracts, all of which are classified as Level 3 inputs.

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

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

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

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

Although we are not aware of any factors that would significantly affect the reasonable fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date and current estimates of fair value may differ significantly from the amounts presented herein.

17. Financial Instruments: Derivatives and Hedging

In the normal course of business, we use a variety of commonly used derivative instruments, such as interest rate swaps, caps, collar and floors, to manage, or hedge interest rate risk. We hedge our exposure to variability in future cash flows for forecasted transactions in addition to anticipated future interest payments on existing debt. We recognize all derivatives on the balance sheet at fair value. Derivatives that are not hedges are adjusted to fair value through earnings. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedge asset, liability, or firm commitment through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. 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 June 30, 2018 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
Interest Rate Swap	$	200,000	1.131	%	July 2016	July 2023	Other Assets	$	15,272
Interest Rate Swap	100,000		1.161	%	July 2016	July 2023	Other Assets	7,496

During the three months ended June 30, 2018 , we recorded a loss on the changes in the fair value of $0.1 million , which is included in interest expense in the consolidated statements of operations. During the six months ended June 30, 2018 , we recorded a loss on the changes in the fair value of $0.3 million , which is included in interest expense in the consolidated statements of operations. During the three months ended June 30, 2017 , we did not record a gain or loss on the changes in the fair value. During the six months ended June 30, 2017 , we recorded a loss on the changes in the fair value of $0.1 million , which is included in interest expense in 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 June 30, 2018 , 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 June 30, 2018 , 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 June 30, 2018 .

Gains and losses on terminated hedges are included in accumulated other comprehensive income, and are recognized into earnings over the term of the related mortgage obligation. Over time, the realized and unrealized gains and losses held in accumulated other comprehensive income will be reclassified into earnings as an adjustment to interest expense in the same periods in which the hedged interest payments affect earnings. We estimate that $2.6 million of the current balance held in accumulated other comprehensive income will be reclassified into interest expense and $1.4 million of the portion related to our share of joint venture accumulated other comprehensive income will be reclassified into equity in net income from unconsolidated joint ventures within the next 12 months.

19. Segment Information

The Company has two reportable segments, real estate and debt and preferred equity investments. We evaluate real estate performance and allocate resources based on earnings 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 six months ended June 30, 2018 and 2017 , and selected asset information as of June 30, 2018 and December 31, 2017 , regarding our operating segments are as follows (in thousands):

Net income (loss) before equity in net gain on sale of interest in unconsolidated joint venture/real estate, purchase price and other fair value adjustments, (loss) gain on sale of real estate net, depreciable real estate reserves, and gain on sale of marketable securities 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 six months ended June 30, 2018 , marketing, general and administrative expenses totaled $22.5 million , and $46.0 million , respectively. For the three and six months ended June 30, 2017 , marketing, general and administrative expenses totaled $24.3 million , and $48.4 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

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

For properties owned since January 1, 2017 and still owned and operated at June 30, 2018 , Same-Store Operating Income is determined as follows (in millions):

Rental, Escalation and Reimbursement Revenues

Rental revenues decreased primarily as a result of the partial sale and deconsolidation of 1515 Broadway and deconsolidation of 919 Third Avenue ($52.1 million), and the sale of 600 Lexington Avenue ($4.9 million).

Escalation and reimbursement revenue decreased primarily as a result of the partial sale and deconsolidation of 1515 Broadway ($8.6 million), and the effect of the deconsolidation of 919 Third Avenue ($5.0 million), partially offset by higher recoveries at our Same-Store properties ($1.8 million).

Investment Income

For the three months ended June 30, 2018 , investment income decreased primarily as a result of previously unrecognized income related to our preferred equity investment in 885 Third Avenue ($9.4 million) in the second quarter of 2017, partially offset by a larger weighted average book balance and an increase in the LIBOR benchmark rate. For the three months ended June 30, 2018 , the weighted average debt and preferred equity investment balance outstanding and weighted average yield were $2.2 billion and 8.8%, respectively, compared to $2.1 billion and 9.4%, respectively, for the same period in 2017 . As of June 30, 2018 , the debt and preferred equity investments had a weighted average term to maturity of 1.9 years, excluding extension options.

Other Income

Other income decreased primarily due to net fees recognized in connection with the closing of the One Vanderbilt venture in the second quarter of 2017 ($10.3 million), partially offset by real estate tax refunds at our Same-Store Properties ($6.2 million) in the second quarter of 2018.

Table of Contents

Property Operating Expenses

Property operating expenses decreased primarily due to the partial sale and deconsolidation of 1515 Broadway and deconsolidation of 919 Third Avenue ($26.1 million), partially offset by increased real estate taxes at our Same-Store Properties ($2.5 million).

Marketing, General and Administrative Expenses

Marketing, general and administrative expenses for the three months ended June 30, 2018 were $22.5 million , or 5.1% of total combined revenues, including our share of joint venture revenues, and an annualized 47 basis points of total combined assets, including our share of joint venture assets compared to $24.3 million , or 5.0% of total revenues including our share of joint venture revenues, and 52 basis points of total assets including our share of joint venture assets for 2017.

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 partial sale and deconsolidation of 1515 Broadway ($9.1 million), the deconsolidation of 919 Third Avenue ($6.6 million) in the first quarter of 2018, and repayment of senior unsecured notes ($2.6 million), partially offset by a higher weighted average balance of the 2017 term loan facility ($3.9 million). The weighted average consolidated debt balance outstanding was $5.9 billion for the three months ended June 30, 2018 , compared to $6.5 billion for the three months ended June 30, 2017 . The consolidated weighted average interest rate was 4.07% for the three months ended June 30, 2018 , as compared to 3.99% for the three months ended June 30, 2017 .

Depreciation and Amortization

Depreciation and amortization decreased primarily as a result of 5-7 Dey Street and 183 & 187 Broadway which were moved to development ($45.5 million) in the first quarter of 2018, the deconsolidation of 919 Third Avenue and partial sale and deconsolidation of 1515 Broadway ($15.3 million), and the sale of 600 Lexington Avenue ($2.5 million).

Equity in Net Income in Unconsolidated Joint Ventures

Equity in net income from unconsolidated joint ventures increased primarily as a result of the partial sale and deconsolidation of 1515 Broadway ($2.3 million), partially offset by the repayment and redemption of certain debt and preferred equity positions accounted for under the equity method ($2.1 million).

Purchase price and other fair value adjustments

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

During the three months ended June 30, 2018 , we recognized a gain on sale related to our interests in 1745 Broadway ($52.0 million), 175-225 Third Avenue ($19.5 million), and Jericho Plaza ($0.1 million). During the three months ended June 30, 2017 , we recognized a gain related to the sale in May 2014 of our ownership interest in 747 Madison Avenue ($13.0 million). The sale did not meet the criteria for sale accounting at that time and, therefore, remained on our consolidated financial statements.

(Loss) Gain on Sale of Real Estate, Net

During the three months ended June 30, 2018 , we recognized a loss on sale related to our interest in 635 Madison ($14.1 million), and 115-117 Stevens Avenue ($0.7 million). During the three months ended June 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 the gain on sale recognized in connection with the sale of 102 Greene Street ($4.9 million).

Depreciable Real Estate Reserves

During the three months ended June 30, 2017 , we recognized depreciable real estate reserves related to 125 Chubb Avenue ($26.6 million), Stamford Towers ($2.1 million), and 520 White Plains Road ($0.4 million).

Escalation and reimbursement revenue decreased primarily as a result of the partial sale and deconsolidation of 1515 Broadway ($18.6 million), and the effect of the deconsolidation of 919 Third Avenue ($10.1 million), partially offset by higher recoveries at our Same-Store properties ($2.8 million).

Investment Income

For the six months ended June 30, 2018 , investment income decreased primarily as a result of previously unrecognized income in the second quarter of 2017 net with 2018 income related to our preferred equity investment in 885 Third Avenue ($6.9 million), partially offset by new originations and a larger weighted average book balance and an increase in the LIBOR benchmark rate. For the six months ended June 30, 2018 , the weighted average debt and preferred equity investment balance outstanding and weighted average yield were $2.1 billion and 9.1%, respectively, compared to $1.9 billion and 9.4%, respectively, for the same period in 2017 . As of June 30, 2018 , the debt and preferred equity investments had a weighted average term to maturity of 1.9 years excluding extension options.

Other Income

Other income increased primarily as a result of real estate tax refunds at our Same-Store Properties ($6.2 million), lease termination income earned at 1185 Avenue of the Americas ($2.9 million), and promote income related to the sale of 1274 Fifth Avenue ($2.1 million), partially offset by net fees recognized in connection with the One Vanderbilt venture in 2017 ($10.3 million).

Table of Contents

Property Operating Expenses

Property operating expenses decreased primarily due to the partial sale and deconsolidation of 1515 Broadway and deconsolidation of 919 Third Avenue ($53.7 million), and the sale of 600 Lexington Avenue ($4.3 million) which was partially offset by increased real estate taxes at our Same-Store Properties ($4.7 million).

Marketing, General and Administrative Expenses

Marketing, general and administrative expenses for the six months ended June 30, 2018 were $46.0 million , or 5.2% of total combined revenues, including our share of joint venture revenues, and annualized 48 basis points of total combined assets, including our share of joint venture assets compared to $48.4 million , or 5.1% of total revenues including our share of joint venture revenues, and 52 basis points of total assets including our share of joint venture assets for 2017 .

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 partial sale and deconsolidation of 1515 Broadway ($18.1 million), the deconsolidation of 919 Third Avenue ($13.3 million) in the first quarter of 2018, and repayment of senior unsecured notes ($5.2 million), partially offset by a higher weighted average balance of the 2017 term loan facility ($7.2 million). The weighted average consolidated debt balance outstanding was $5.7 billion for the six months ended June 30, 2018 , compared to $6.6 billion for the six months ended June 30, 2017 . The consolidated weighted average interest rate was 4.03% for the six months ended June 30, 2018 , as compared to 4.04% for the six months ended June 30, 2017 .

Depreciation and Amortization

Depreciation and amortization decreased primarily as a result of 5-7 Dey Street and 183 & 187 Broadway which were moved to development ($50.1 million) in the first quarter of 2018, the deconsolidation of 919 Third Avenue and partial sale and deconsolidation of 1515 Broadway ($29.8 million), and the sale of 600 Lexington Avenue ($5.9 million).

Equity in Net Income in Unconsolidated Joint Venture

Equity in net income from unconsolidated joint ventures decreased primarily as a result the repayment and redemption of certain debt and preferred equity positions accounted for under the equity method ($2.3 million), partially offset by the partial sale and deconsolidation of 1515 Broadway ($2.3 million) in the first quarter of 2018.

Purchase price and other fair value adjustments

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

In May, 2018, the Company was the successful bidder at the foreclosure of 2 Herald Square, at which time the Company's $250.5 million outstanding principal balance and $7.7 million accrued interest balance receivables were credited to our equity investment in the property. We recorded the assets acquired and liabilities assumed at fair value. This resulted in the recognition of a fair value adjustment of $11.1 million, which is reflected on the Company's consolidated statement of operations within purchase price and other fair value adjustments. This fair value was allocated to the assets and liabilities, including identified intangibles of the property.

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

During the six months ended June 30, 2018 , we recognized a gain on sale related to our joint venture interests in 1745 Broadway ($52.0 million), 175-225 Third Avenue ($19.5 million), and Jericho Plaza ($0.1 million), and a loss on sale related to our deconsolidation of Stonehenge Village ($5.5 million). During the six months ended June 30, 2017 , we recognized a gain related to the sale in May 2014 of our ownership interest in 747 Madison Avenue ($13.0 million), which did not meet the criteria for sale accounting at that time and, therefore, remained on our consolidated financial statements, and a gain on sale associated with the sale of part of our joint venture interest in the Stonehenge Portfolio ($0.9 million).

(Loss) Gain on Sale of Real Estate, Net

During the six months ended June 30, 2018 , we recognized a gain on sale related to our interests in 600 Lexington ($23.8 million) and we recognized a loss on sale related to our interest in 635 Madison ($14.1 million), and 115-117 Stevens Avenue ($0.7 million). During the six months ended June 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 sale of the property at 102 Greene Street ($4.9 million).

Depreciable Real Estate Reserves

During the six months ended June 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.

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, common stock repurchases, repurchases or repayments of outstanding indebtedness (which may include exchangeable debt) and for debt and preferred equity investments may include:


(1)	Cash flow from operations;


(2)	Cash on hand;


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


(4)	Borrowings under the 2017 credit facility;


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


(6)	Proceeds from common or preferred equity or debt offerings by the Company, 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 June 30, 2018 were as follows (in thousands):

As of June 30, 2018 , we had $315.8 million of consolidated cash on hand, inclusive of $28.6 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, cash equivalents, and restricted cash were $380.0 million and $380.9 million at June 30, 2018 and 2017 , respectively, representing a decrease of $0.9 million . The decrease was a result of the following changes in cash flows (in thousands):

Table of Contents



	Six Months Ended June 30,
	2018			2017			Increase (Decrease)
Net cash provided by operating activities	$	246,212		$	310,850		$	(64,638	)
Net cash provided by (used in) investing activities	$	268,064		$	(237,587	)	$	505,651
Net cash used in financing activities	$	(384,322	)	$	(62,306	)	$	(322,016	)

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

Cash is used in investing activities to fund acquisitions, development or redevelopment projects and recurring and nonrecurring capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing and property management skills and invest in existing buildings that meet our investment criteria. During the six months ended June 30, 2018 , when compared to the six months ended June 30, 2017 , the change in investing cash flows was due to the following activities (in thousands):



Acquisitions of real estate property	$	(9,714	)

Funds spent on capital expenditures, which are comprised of building and tenant improvements, decreased from $165.3 million for the six months ended June 30, 2017 to $96.6 million for the six months ended June 30, 2018 . The decrease in capital expenditures relates primarily to lower costs incurred in connection with the redevelopment of properties.

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

Fourth Amended and Restated 2005 Stock Option and Incentive Plan

The Fourth Amended and Restated 2005 Stock Option and Incentive Plan, or the 2005 Plan, was approved by the Company's board of directors in April 2016 and its stockholders in June 2016 at the Company's annual meeting of stockholders. Subject to adjustments upon certain corporate transactions or events, awards with respect to up to a maximum of 27,030,000 fungible units may be granted as options, restricted stock, phantom shares, dividend equivalent rights and other equity-based awards under the 2005 Plan. As of June 30, 2018 , 7.4 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.

2014 Outperformance Plan

The cost of the 2014 Outperformance Plan ( $27.9 million , subject to forfeitures), based on the portion of the 2014 Outperformance Plan granted prior to termination, was amortized into earnings through December 31, 2017 . We recorded no compensation expense for the three and six months ended June 30, 2018 , respectively, related to the 2014 Outperformance Plan. We recorded compensation expense of $4.3 million and $6.3 million for the three and six months ended June 30, 2017 , respectively, related to the 2014 Outperformance Plan.

Deferred Compensation Plan for Directors

As of June 30, 2018 , there were 111,356 phantom stock units outstanding pursuant to our Non-Employee Director's Deferral Program.

Market Capitalization

At June 30, 2018 , borrowings under our mortgages and other loans payable, 2017 credit facility, senior unsecured notes, trust preferred securities and our share of joint venture debt represented 50.9% of our combined market capitalization of $19.6 billion (based on a common stock price of $100.53 per share, the closing price of our common stock on the NYSE on June 30, 2018 ). Market capitalization includes our consolidated debt, common and preferred stock and the conversion of all units of limited partnership interest in the Operating Partnership, and our share of joint venture debt.

Indebtedness

The table below summarizes our consolidated mortgages and other loans payable, 2017 credit facility, senior unsecured notes and trust preferred securities outstanding at June 30, 2018 and December 31, 2017 , (amounts in thousands).

Variable rate	3.31		%	2.76		%

The variable rate debt shown above generally bears interest at an interest rate based on 30-day LIBOR ( 2.09% and 1.56% at June 30, 2018 and December 31, 2017 , respectively). Our consolidated debt at June 30, 2018 had a weighted average term to maturity of 4.70 years.

Certain of our debt and equity investments and other investments, with a carrying value of $1.6 billion at June 30, 2018 , are variable rate investments which mitigate our exposure to interest rate changes on our unhedged variable rate debt.

2017 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 2018 would increase our consolidated annual interest cost, net of interest income from variable rate debt and preferred equity investments, by $4.9 million and would increase our share of joint venture annual interest cost by $14.9 million . At June 30, 2018 , 73.7% of our $2.2 billion debt and preferred equity portfolio is indexed to LIBOR.

Table of Contents

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

Our long-term debt of $3.8 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 June 30, 2018 bore interest based on a spread of LIBOR plus 100 basis points to LIBOR plus 350 basis points.

Contractual Obligations

Refer to our 2017 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 six months ended June 30, 2018 .

Off-Balance Sheet Arrangements

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

Capital Expenditures

We estimate that for the remainder of the year ending December 31, 2018 , we expect to incur $114.7 million of recurring capital expenditures and $31.5 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 $221.9 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 $3.25 per share, we would pay $278.6 million in dividends to our common stockholders on an annual basis. Before we pay any dividend, whether for Federal income tax purposes or otherwise, which would only be paid out of available cash to the extent permitted under the 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.

Table of Contents

Insurance

We maintain “all-risk” property and rental value coverage (including coverage regarding the perils of flood, earthquake and terrorism, excluding nuclear, biological, chemical, and radiological terrorism ("NBCR")), within three property insurance programs and liability insurance. Separate property and liability coverage may be purchased on a stand-alone basis for certain assets, such as the development of One Vanderbilt. Additionally, our captive insurance company, Belmont Insurance Company, or Belmont, provides coverage for NBCR terrorist acts above a specified trigger, although if 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. As of June 30, 2018 , our second captive insurance company, Ticonderoga Insurance Company, or Ticonderoga, reinsures the NBCR risk that was retained by Belmont. However, there is no assurance that in the future we will be able to procure coverage at a reasonable cost. Further, if we experience losses that are uninsured or that exceed policy limits, we could lose the capital invested in the damaged properties as well as the anticipated future cash flows from those properties. Additionally, our debt instruments contain customary covenants requiring us to maintain insurance and we could default under debt our instruments if the cost and/or availability of certain types of insurance make it impractical or impossible to comply with such covenants relating to insurance. Belmont provides coverage solely on properties owned by the Company or its affiliates.

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

Funds from Operations

FFO is a widely recognized non-GAAP 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 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.

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
