Notes to Consolidated Financial Statements

September 30, 2017

(unaudited)

1. Organization and Basis of Presentation

Reckson Operating Partnership, L.P., or ROP, commenced operations on June 2, 1995. The sole general partner of ROP is Wyoming Acquisition GP LLC., or WAGP, a wholly-owned subsidiary of SL Green Operating Partnership, L.P., or the Operating Partnership. The sole limited partner of ROP is the Operating Partnership. The Operating Partnership is 95.55% owned by SL Green Realty Corp., or SL Green, as of September 30, 2017. SL Green is a self-administered and self-managed real estate investment trust, and is the sole managing general partner of the Operating Partnership. Unless the context requires otherwise, all references to "we," "our," "us" and the "Company" means ROP and all entities owned or controlled by ROP.

ROP is engaged in the acquisition, ownership, management and operation of commercial and residential real estate properties, principally office properties, and also owns land for future development, located in New York City, Westchester County, Connecticut and New Jersey, which collectively is also known as the New York Metropolitan area.

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

Location	Type	Number of Properties	Approximate Square Feet (unaudited)	Weighted Average Occupancy(1) (unaudited)
Commercial:
Manhattan	Office	16	8,463,245	95.7	%
	Retail(2)(3)	5	364,816	98.0	%
	Fee Interest	1	176,530	100.0	%
		22	9,004,591	95.9	%
Suburban	Office(4)	15	2,746,000	84.6	%
	Retail	1	52,000	100.0	%
		16	2,798,000	84.9	%
Total commercial properties		38	11,802,591	93.2	%
Residential:
Manhattan	Residential(2)	—	222,855	88.0	%
Total portfolio		38	12,025,446	93.2	%

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

(2) As of September 30, 2017, we owned a building at 315 West 33rd Street, also known as The Olivia, that was comprised of approximately 270,132 square feet (unaudited) of retail space and approximately 222,855 square feet (unaudited) of residential space. For the purpose of this report, we have included this building in the number of retail properties we own. However, we have included only the retail square footage in the retail approximate square footage, and have listed the balance of the square footage as residential square footage.

(3) Includes two unconsolidated joint venture retail properties at 131-137 Spring Street comprised of approximately 68,342 square feet.

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

As of September 30, 2017, we held debt and preferred equity investments with a book value of $2.2 billion, including $0.1 billion of debt and preferred equity investments and other financing receivables that are included in other balance sheet line items other than the Debt and Preferred Equity Investments line item.

Notes to Consolidated Financial Statements (cont.)

September 30, 2017

(unaudited)

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 at September 30, 2017 and the results of operations for the periods presented have been included. The operating results for the period presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. These financial statements should be read in conjunction with the financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2016.

The consolidated balance sheet at December 31, 2016 has been derived from the audited financial statements as of that date but do not include all the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

2. Significant Accounting Policies

Principles of Consolidation

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

We consolidate a variable interest entity, or VIE, in which we are considered the primary beneficiary. The primary beneficiary is the entity that has (i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE.

Investment in Commercial Real Estate Properties

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted) to be generated by the property is less than the carrying value of the property. To the extent impairment has occurred, the loss will be measured as the excess of the carrying amount of the property over the calculated fair value of the property. We also evaluate our real estate properties for potential impairment when a real estate property has been classified as held for sale. Real estate assets held for sale are valued at the lower of either their carrying value or fair value less costs to sell. We do not believe that there were any indicators of impairment at any of our consolidated properties at September 30, 2017. We recorded $0.4 million depreciable real estate reserves for the three months ended September 30, 2017, and aggregate depreciable real estate reserves of $85.7 million for the nine months ended September 30, 2017. See Note 4, "Property Dispositions".

We allocate the purchase price of real estate to land and building (inclusive of tenant improvements) and, if determined to be material, intangibles, such as the value of above- and below-market leases and origination costs associated with the in-place leases. We depreciate the amount allocated to building (inclusive of tenant improvements) over their estimated useful lives, which generally range from three to 40 years. We amortize the amount allocated to the above- and below-market leases over the remaining term of the associated lease, which generally range from one to 14 years, and record it as either an increase (in the case of below-market leases) or a decrease (in the case of above-market leases) to rental income. We amortize the amount allocated to the values associated with in-place leases over the expected term of the associated lease, which generally ranges from one to 14 years. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off. The tenant improvements and origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). We assess fair value of the leases based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and market/economic conditions that may affect the property. To the extent acquired leases contain fixed rate renewal options that are below-market and determined to be material, we amortize such below-market lease value into rental income over the renewal period.

Notes to Consolidated Financial Statements (cont.)

September 30, 2017

(unaudited)

We recognized $4.3 million and $12.7 million of rental revenue for the three and nine months ended September 30, 2017, and $8.1 million and $15.9 million of rental revenue for the three and nine months ended September 30, 2016, for the amortization of aggregate below-market leases in excess of above-market leases and a reduction in lease origination costs, resulting from the allocation of the purchase price of the applicable properties.

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

Fair Value Measurements

See Note 12, "Fair Value Measurements."

Investments in Unconsolidated Joint Ventures

We assess our investments in unconsolidated joint ventures for recoverability, and if it is determined that a loss in value of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments for impairment based on the joint ventures' projected discounted cash flows. We do not believe that the values of any of our equity investments were impaired at September 30, 2017.

Reserve for Possible Credit Losses

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

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the net fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during the three and nine months ended September 30, 2017 and 2016.

Income Taxes

ROP is a disregarded entity of SL Green Operating Partnership, L.P. for federal income tax purposes, and, as a result, all income and losses of ROP are considered income and losses of SL Green Operating Partnership, L. P. No provision has been made for income taxes in the consolidated financial statements since such taxes, if any, are the responsibility of the individual partners of SL Green Operating Partnership, L.P.

Shares Contributed by Parent Company

We present shares of SL Green common stock as a contra-equity account in 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 New York City. See Note 5, "Debt and Preferred Equity Investments." We perform ongoing credit evaluations of our tenants and require most tenants to provide security deposits or letters of credit. Though these security deposits and letters of credit are insufficient to meet the total value of a tenant's lease obligation, they are a measure of good faith and a source of funds to offset the economic costs associated with lost revenue and the costs associated with re-tenanting a space.

The properties in our real estate portfolio are primarily located in Manhattan. We also have properties located in Brooklyn, Westchester County, Connecticut and New Jersey. The tenants located in our buildings operate in various industries. No tenant in our portfolio accounted for more than 5.0% of our share of annualized cash rent, including our share of joint venture annualized rent, at September 30, 2017. For the three months ended September 30, 2017, 13.8%, 9.1%, 7.4%, 7.2%, 7.1%, 6.3%, 6.1%, and 5.9% of our share of cash rent, including our share of joint venture annualized rent was attributable to 1185 Avenue of the Americas, 625 Madison Avenue, 919 Third Avenue, 750 Third Avenue, 810 Seventh Avenue, 555 West 57th Street, 125 Park Avenue. and 1350 Avenue of the Americas, respectively. Our share of annualized cash rent for all other properties was below 5.0%.

Reclassification

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

Accounting Standards Updates

In August 2017, the FASB issued Accounting Standards Update (ASU) No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. The amendments in the new standard will permit more flexibility in hedging interest rate risk for both variable rate and fixed rate financial instruments. The standard will also enhance the presentation of hedge results in the financial statements. The guidance is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. The Company has not yet adopted the guidance, and does not expect a material impact on the Company’s consolidated financial statements when the new standard is implemented.

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

In January, 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The guidance clarifies the definition of a business and provides guidance to assist with determining whether transactions should be accounted for as acquisitions of assets or businesses. The main provision is that an acquiree is not a business if substantially all of the fair value of the gross assets is concentrated in a single identifiable asset or group of assets. The Company adopted the guidance on the issuance date effective January 5, 2017. The Company expects that most of our real estate acquisitions will be considered asset acquisitions under the new guidance and that transaction costs will be capitalized to the investment basis which is then subject to a purchase price allocation based on relative fair value.

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

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

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

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

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

In January 2016, the FASB issued ASU 2016-01 (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and to record changes in instruments-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income. The guidance is effective for fiscal years beginning after December 15, 2017, and for interim periods therein. The Company has not yet adopted this new guidance and is currently evaluating the impact of adopting this new accounting standard on the Company’s consolidated financial statements.

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

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

3. Property Acquisitions

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

4. Properties Held for Sale and Property Dispositions

Properties Held for Sale

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

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

Property Dispositions

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

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

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

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

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

(1) Carrying value is net of discounts, premiums, original issue discounts and deferred origination fees.

(2) Represents contractual maturity, excluding any unexercised extension options.

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

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

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

(6) This loan was repaid in June 2017.

(7) This loan was repaid in March 2017.

(8) This loan was extended in October 2017.

(9) This loan was extended in January 2017.

(10) This loan was extended in September 2017.

(11) $66.1 million of outstanding principal was syndicated in February 2017.

(12) This loan was repaid in September 2017.

(13) This loan was contributed to a joint venture in May 2017.

Preferred Equity Investments

As of September 30, 2017 and December 31, 2016, we held the following preferred equity investments with an aggregate weighted average current yield of 6.98% at September 30, 2017 (in thousands):

Type	September 30, 2017 Future Funding Obligations		September 30, 2017 Senior Financing		September 30, 2017 Carrying Value (1)		December 31, 2016 Carrying Value (1)		Mandatory Redemption (2)

Preferred Equity(5)	—		—		—		37,893
Total	$	—	$	272,000	$	143,980	$	47,875

(1) Carrying value is net of deferred origination fees.

(2) Represents contractual maturity, excluding any unexercised extension options.

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

(4) This investment was redeemed in May 2017.

(5) This investment was redeemed in April 2017.

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

We have determined that we have one portfolio segment of financing receivables at September 30, 2017 and 2016 comprising commercial real estate which is primarily recorded in debt and preferred equity investments. Included in other assets is an additional amount of financing receivables totaling $94.8 million and $144.5 million at September 30, 2017 and December 31, 2016, respectively. No financing receivables were 90 days past due at September 30, 2017.

6. Investments in Unconsolidated Joint Ventures

We have investments in several real estate joint ventures with various partners. As of September 30, 2017, none of our investments in unconsolidated joint ventures are VIEs. The table below provides general information on each of our joint ventures as of September 30, 2017:

Property	Partner	Ownership Interest (1)	Economic Interest(1)	Unaudited Approximate Square Feet	Acquisition Date(2)	Acquisition Price(2) (in thousands)
131-137 Spring Street	Invesco Real Estate	20.00%	20.00%	68,342	August 2015	$	277,750
Mezzanine Loan (3)	Private Investors	33.33%	33.33%	—	May 2017	15,000

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

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

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

Acquisition, Development and Construction Arrangements

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

7. Mortgages and Other Loans Payable

The first mortgages and other loans payable collateralized by the respective properties and assignment of leases or debt investments at September 30, 2017 and December 31, 2016, respectively, were as follows (amounts in thousands):

Property	Maturity Date	Interest Rate (1)		September 30, 2017			December 31, 2016

(1) Effective weighted average interest rate for the quarter ended September 30, 2017.

(2) We own a 51.0% controlling interest in the consolidated joint venture that is the borrower on this loan.

At September 30, 2017 and December 31, 2016, the gross book value of the properties and debt and preferred equity investments collateralizing the mortgages and other loans payable, not including assets held for sale, was approximately $2.5 billion and $1.7 billion, respectively.

Master Repurchase Agreements

The Company has entered into two Master Repurchase Agreements, or MRAs, known as the 2016 MRA and 2017 MRA, which provide us with the ability to sell certain debt investments with a simultaneous agreement to repurchase the same at a certain date or on demand. We seek to mitigate risks associated with our repurchase agreement by managing the credit quality of our assets, early repayments, interest rate volatility, liquidity, and market value. The margin call provisions under our repurchase facilities permit valuation adjustments based on capital markets activity, and are not limited to collateral-specific credit marks. To monitor credit risk associated with our debt investments, our asset management team regularly reviews our investment portfolio and is in contact with our borrowers in order to monitor the collateral and enforce our rights as necessary. The risk associated with potential margin calls is further mitigated by our ability to recollateralize the facility with additional assets from our portfolio of debt investments, our ability to satisfy margin calls with cash or cash equivalents and our access to additional liquidity through the 2012 credit facility, as defined below.

In June 2017, we entered into the 2017 MRA, with a maximum facility capacity of $300.0 million. The facility bears interest on a floating rate basis at a spread to 30-day LIBOR based on the pledged collateral and advance rate and has an initial one year term, with twoone year extension options. At September 30, 2017, the facility had a carrying value of $(1.1) million, representing deferred financing costs presented within other liabilities.

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

2012 Credit Facility

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

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

At September 30, 2017, the applicable spread was 125 basis points for the revolving credit facility and 140 basis points for the term loan facility. At September 30, 2017, the effective interest rate was 2.49% for the revolving credit facility and 2.63% for the term loan facility. We are required to pay quarterly in arrears a 12.5 to 30 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. As of September 30, 2017, the facility fee was 25 basis points.

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

ROP, SL Green, and the Operating Partnership are all borrowers jointly and severally obligated under the 2012 credit facility. None of SL Green's other subsidiaries are obligors under the 2012 credit facility.

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

Restrictive Covenants

The terms of the 2012 credit facility, as amended, and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, SL Green's 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 SL Green will not during any time when a default is continuing, make distributions with respect to SL Green's common stock or other equity interests, except to enable SL Green to continue to qualify as a REIT for Federal income tax purposes. As of September 30, 2017 and 2016, we were in compliance with all such covenants.

Cleaning/ Security/ Messenger and Restoration Services

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

Income earned from profit participation, which is included in other income on the consolidated statements of operations, was $0.8 million and $2.5 million for the three and nine months ended September 30, 2017 and 2016, respectively.

We also recorded expenses for these services, inclusive of capitalized expenses, of $2.6 million and and $7.1 million for the three and nine months ended September 30, 2017, respectively, for these services (excluding services provided directly to tenants), and $1.2 million and $6.0 million for the three and nine months ended September 30, 2016, respectively.

Allocated Expenses from SL Green

Property operating expenses include an allocation of salary and other operating costs from SL Green based on square footage of the related properties. Such amount was approximately $3.0 million and $9.2 million for the three and nine months ended September 30, 2017, respectively. The amount was $2.8 million and $8.2 million for the three and nine months ended September 30, 2016, respectively.

Insurance

We obtained insurance coverage through an insurance program administered by SL Green. In connection with this program, we incurred insurance expense of approximately $1.3 million and $4.1 million for the three and nine months ended September 30, 2017. We incurred insurance expense of approximately $1.5 million and $4.4 million for the three and nine months ended September 30, 2016.

10. Preferred Units

Through a consolidated subsidiary, we have authorized up to 109,1613.50% Series A Preferred Units of limited partnership interest, or the Greene Series A Preferred Units, with a liquidation preference of $1,000.00 per unit. In August 2015, the Company issued 109,161 Greene Series A Preferred Units in conjunction with an acquisition. The Greene Series A Preferred unitholders receive annual dividends of $35.00 per unit paid on a quarterly basis and dividends are cumulative, subject to certain provisions. The Greene Series A Preferred Units can be redeemed at any time, at the option of the unitholder, either for cash or are convertible on a one-for-one basis, into the Series B Preferred Units of limited partnership interest, or the Greene Series B Preferred Units. The Greene Series B Preferred Units can be converted at any time, at the option of the unitholder, into a number of common stock equal to 6.71348 shares of SL Green common stock for each Greene Series B Preferred Unit. As of September 30, 2017, no Greene Series B Preferred Units have been issued.

ASC 815 Derivatives and Hedging requires bifurcation of certain embedded derivative instruments, such as conversion features in convertible equity instruments, and their measurement at fair value for accounting purposes. The conversion feature embedded in the Subsidiary Series A Preferred Units was evaluated, and it was determined that the conversion feature should be bifurcated from its host instrument and accounted for as a freestanding derivative. The derivative is reported as a derivative liability in accrued interest and other liabilities on the accompanying consolidated balance sheet and is adjusted to its fair value at each reporting date, with a corresponding adjustment to interest expense, net of interest income. The embedded derivative for the Subsidiary Series A Preferred Units was initially recorded at a fair value of zero on July 22, 2015, the date of issuance. At December 31, 2016, the carrying amount of the derivative was adjusted to its fair value of zero, with a corresponding adjustment to preferred units and interest expense, net of interest income. At September 30, 2017, the carrying amount and fair value of the derivative remained at zero.

11. Partners' Capital

Since consummation of the Merger on January 25, 2007, the Operating Partnership has owned all the economic interests in ROP either by direct ownership or by indirect ownership through our general partner, which is its wholly-owned subsidiary.

Intercompany transactions between SL Green and ROP are generally recorded as contributions and distributions.

12. Fair Value Measurements

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

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

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

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

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

The following table provides the carrying value and fair value of these financial instruments as of September 30, 2017 and December 31, 2016 (in thousands):

	September 30, 2017				December 31, 2016
	Carrying Value (1)		Fair Value		Carrying Value (1)		Fair Value
Debt and preferred equity investments	$	2,020,739	(2)		$	1,640,412	(2)
Fixed rate debt	$	2,349,934	$	2,441,240	$	2,099,880	$	2,183,042
Variable rate debt	847,642		855,640		567,642		580,083
	$	3,197,576	$	3,296,880	$	2,667,522	$	2,763,125

(1) Amounts exclude net deferred financing costs.

(2) At September 30, 2017, debt and preferred equity investments had an estimated fair value ranging between $2.0 billion and $2.2 billion. At December 31, 2016, debt and preferred equity investments had an estimated fair value ranging between $1.6 billion and $1.8 billion.

Disclosure about fair value of financial instruments was based on pertinent information available to us as of September 30, 2017 and December 31, 2016. 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.

13. Financial Instruments: Derivatives and Hedging

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

of our designated derivative instruments are effective hedging instruments. As of September 30, 2017, the Company had not designated any interest rate swap agreements on any debt investment.

Gains and losses on terminated hedges are included in accumulated other comprehensive loss, and are recognized into earnings over the term of the related senior unsecured notes. As of September 30, 2017 and December 31, 2016, the deferred net losses from these terminated hedges, which are included in accumulated other comprehensive loss relating to net unrealized loss on derivative instruments, was approximately $1.3 million and $1.6 million, respectively.

Over time, the realized and unrealized gains and losses held in accumulated other comprehensive loss will be reclassified into earnings as an adjustment to interest expense in the same periods in which the hedged interest payments affect earnings. We estimate that $0.4 million of the current balance held in accumulated other comprehensive loss will be reclassified into interest expense within the next 12 months.

The following table presents the effect of our derivative financial instruments that are designated and qualify as hedging instruments on the consolidated statements of operations for the three months ended September 30, 2017 and 2016, respectively (in thousands):

Legal Proceedings

As of September 30, 2017, we were not involved in any material litigation nor, to management's knowledge, was any material litigation threatened against us or our portfolio which if adversely determined could have a material adverse impact on us.

Guarantees

15. Segment Information

We are engaged in acquiring, owning, managing and leasing commercial properties in Manhattan, Brooklyn, Westchester County, Connecticut and New Jersey and have two reportable segments, real estate and debt and preferred equity investments. We evaluate real estate performance and allocate resources based on earnings contribution to income from continuing operations.

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

Selected consolidated results of operations for the three and nine months ended September 30, 2017 and 2016, and selected asset information as of September 30, 2017 and December 31, 2016, regarding our operating segments are as follows (in thousands):

December 31, 2016	6,785,305		1,969,308		8,754,613

Income from continuing operations represents total revenues less total expenses for the real estate segment and total investment income less allocated interest expense for the debt and preferred equity segment. Interest costs for the debt and preferred equity segment includes actual costs incurred for borrowings on the 2016 MRA and 2017 MRA. Interest is imputed on the investments that do not collateralize the 2016 MRA or 2017 MRA using our corporate borrowing cost. We also allocate loan loss reserves, net of recoveries, and transaction related costs to the debt and preferred equity segment. We do not allocate marketing, general and administrative expenses to the debt and preferred equity segment since the use of personnel and resources is dependent on transaction volume between the two segments and varies period over period. In addition, we base performance on the individual segments prior to allocating marketing, general and administrative expenses. For the three and nine months ended September 30, 2017, and 2016, marketing, general and administrative expenses totaled $0.1 million, $0.2 million, $0.3 million, and $0.6 million, respectively. All other expenses, except interest, relate entirely to the real estate assets.

There were no transactions between the above two segments.

The table below reconciles income from continuing operations to net income for the three and nine months ended September 30, 2017 and 2016 (in thousands):

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

OPERATIONS

Overview

Reckson Operating Partnership, L.P., or ROP, commenced operations on June 2, 1995. The sole general partner of ROP is Wyoming Acquisition GP LLC., or WAGP, a wholly-owned subsidiary of SL Green Operating Partnership, L.P., or the Operating Partnership. The sole limited partner of ROP is the Operating Partnership. SL Green Realty Corp., or SL Green, is the general partner of the Operating Partnership. Unless the context requires otherwise, all references to "we," "our," "us" and the "Company" means ROP and all entities owned or controlled by ROP.

ROP is engaged in the acquisition, ownership, management and operation of commercial and residential real estate properties, principally office properties, and also owns land for future development, located in New York City, Westchester County, Connecticut and New Jersey, which collectively is also known as the New York Metropolitan area.

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

Location	Type	Number of Properties	Approximate Square Feet (unaudited)	Weighted Average Occupancy(1) (unaudited)
Commercial:
Manhattan	Office	16	8,463,245	95.7	%
	Retail(2)(3)	5	364,816	98.0	%
	Fee Interest	1	176,530	100.0	%
		22	9,004,591	95.9	%
Suburban	Office(4)	15	2,746,000	84.6	%
	Retail	1	52,000	100.0	%
		16	2,798,000	84.9	%
Total commercial properties		38	11,802,591	93.2	%
Residential:
Manhattan	Residential(2)	—	222,855	88.0	%
Total portfolio		38	12,025,446	93.2	%

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

(2) As of September 30, 2017, we owned a building at 315 West 33rd Street, also known as The Olivia, that was comprised of approximately 270,132 square feet (unaudited) of retail space and approximately 222,855 square feet (unaudited) of residential space. For the purpose of this report, we have included this building in the number of retail properties we own. However, we have included only the retail square footage in the retail approximate square footage, and have listed the balance of the square footage as residential square footage.

(3) Includes two unconsolidated joint venture retail properties at 131-137 Spring Street comprised of approximately 68,342 square feet.

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

Critical Accounting Policies

Refer to the 2016 Annual Report on Form 10-K of the Company and the Operating Partnership for a discussion of our critical accounting policies, which include investment in commercial real estate properties, investment in unconsolidated joint ventures, revenue recognition, allowance for doubtful accounts, reserve for possible credit losses and derivative instruments. There have been no changes to these accounting policies during the nine months ended September 30, 2017.

Results of Operations

Comparison of the three months ended September 30, 2017 to the three months ended September 30, 2016

The following comparison for the three months ended September 30, 2017, or 2017, to the three months ended September 30, 2016, or 2016, makes reference to the effect of the following:

i. “Same-Store Properties,” which represents all operating properties owned by us at January 1, 2016 and still owned by us in the same manner at September 30, 2017 (Same-Store Properties totaled34 of our 36 consolidated operating properties),

ii. “Acquisition Properties,” which represents all properties or interests in properties acquired in 2017 and 2016 and all non-Same-Store Properties, including properties that are under development, redevelopment or were deconsolidated during the period,

iii. "Disposed Properties" which represents all properties or interests in properties sold or partially sold in 2017 and 2016, and

iv. “Other,” which represents corporate level items not allocable to specific properties,

Net income	64,710			102,923			(38,213		)	(37.1	)%

Rental, Escalation and Reimbursement Revenues

Rental revenue increased primarily as a result of our Same-Store Properties ($4.0 million), which included 711 Third Avenue ($2.3 million), and 919 Third Avenue ($1.7 million), partially offset by Disposed Properties ($3.2 million), which included the sale of 680/750 Washington Boulevard in the third quarter of 2017 ($2.2 million) and 520 White Plains Road in the second quarter of 2017 ($1.0 million).

Escalation and reimbursement revenue decreased primarily as a result of Disposed Properties ($0.4 million) and lower recoveries at our Same-Store properties ($2.0 million).

27

Investment Income

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

Other Income

Other income decreased primarily as a result lower termination fee income at our Same-Store Properties ($0.1 million).

Property Operating Expenses

Property operating expenses increased primarily as a result of higher real estate taxes resulting from higher assessed values and tax rates at our Same-Store Properties ($1.9 million), partially offset by the sale of 520 White Plains Road ($0.7 million) in the second quarter of 2017.

Transaction Related Costs

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

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

Interest expense and amortization of financing costs, net of interest income, increased primarily as a result of the refinance of 315 West 33rd Street in the first quarter of 2017 ($2.8 million), a higher weighted average balance of the 2012 revolving credit facility ($2.1 million), a higher weighted average balance of the 2012 term loan facility ($1.6 million), and increased interest expense related to our repurchase agreements ($1.2 million). The weighted average consolidated debt balance outstanding was $3.4 billion for the three months ended September 30, 2017 as compared to $2.6 billion for the three months ended September 30, 2016. The weighted average consolidated interest rate was 3.82% for the three months ended September 30, 2017 as compared to 3.85% for the three months ended September 30, 2016.

Depreciation and Amortization

Depreciation and amortization decreased primarily as a result of the acquisition of 110 Greene Street ($5.6 million), partially offset by increased depreciation at 919 Third Avenue ($2.2 million).

Equity in Net Income from Unconsolidated Joint Venture

Equity in net income from unconsolidated joint ventures decreased primarily as a result of the repayment of a debt investment early in the second quarter of 2017 ($1.5 million).

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

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

28

Comparison of the nine months ended September 30, 2017 to the nine months ended September 30, 2016

The following comparison for the nine months ended September 30, 2017, or 2017, to the nine months ended September 30, 2016, or 2016, makes reference to the effect of the following:

i. “Same-Store Properties,” which represents all operating properties owned by us at January 1, 2016 and still owned by us in the same manner at September 30, 2017 (Same-Store Properties totaled34 of our 36 consolidated operating properties),

ii. “Acquisition Properties,” which represents all properties or interests in properties acquired in 2017 and 2016 and all non-Same-Store Properties, including properties that are under development, redevelopment or were deconsolidated during the period,

iii. "Disposed Properties" which represents all properties or interests in properties sold or partially sold in 2017 and 2016, and

Net income	138,849			243,144			(104,295		)	(42.9	)%

Rental, Escalation and Reimbursement Revenues

Rental revenue increased primarily as a result of increases in rents and occupancy at our Same-Store Properties ($21.2 million), which included 919 Third Avenue ($7.8 million), 711 Third Avenue ($7.7 million), and 125 Park Avenue ($3.3 million), partially offset by the Disposed Properties ($4.0 million), which included the sale of 680/750 Washington Boulevard in the third quarter of 2017 ($2.4 million) and 520 White Plains Road in the second quarter of 2017 ($1.6 million).

Escalation and reimbursement revenue decreased primarily as a result of the Disposed Properties ($0.7 million) which included the sale of680/750 Washington Boulevard in the third quarter of 2017 ($0.5 million) and 520 White Plains Road in the second quarter of 2017 ($0.2 million) as well as lower recoveries at our Same-Store Properties ($3.6 million).

29

Investment Income

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

Other Income

Other income decreased primarily as a result of the reversal of $1.2 million of fees, which were recognized in the prior year, as a result of the Company being relieved of the obligation to perform certain services.

Property Operating Expenses

Property operating expenses increased primarily as a result of higher real estate taxes resulting from higher assessed values and tax rates at our Same-Store Properties ($5.6 million), partially offset by decreased operating expenses from our Disposed Properties ($2.4 million) which included the sale 520 White Plains Road ($1.3 million) in the second quarter of 2017, and the sale of 680/750 Washington Boulevard ($1.0 million) in the third quarter of 2017.

Transaction Related Costs

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

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

Interest expense and amortization of financing costs, net of interest income, increased primarily as a result of the refinance of 315 West 33^rd Street in the first quarter of 2017 ($7.7 million), and increased interest expense related to our repurchase agreements ($1.2 million). The weighted average consolidated debt balance outstanding was $3.1 billion for the nine months ended September 30, 2017 as compared to $3.1 billion for the nine months ended September 30, 2016. The weighted average consolidated interest rate was 3.86% for the nine months ended September 30, 2017 as compared to 3.57% for the nine months ended September 30, 2016.

Depreciation and Amortization

Depreciation and amortization decreased primarily as a result of the Disposed Properties ($3.1 million), which included the sale of 680/750 Washington Boulevard ($1.9 million) in the third quarter of 2017, and the sale of 520 White Plains Road ($1.2 million) in the second quarter of 2017.

Equity in Net Income from Unconsolidated Joint Venture

Equity in net income from unconsolidated joint ventures decreased primarily as a result of the second quarter 2017 repayment of a debt investment which was contributed to an unconsolidated joint venture in the third quarter of 2016 ($1.4 million), partially offset by the contribution of a debt investment to an unconsolidated joint venture in the second quarter of 2017 ($1.3 million).

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

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

Depreciable Real Estate Reserves

During the nine months ended September 30, 2017, we recorded a $85.7 million charge in connection with 520 White Plains Road in Tarrytown, NY, and 680/750 Washington Boulevard in Stamford, Connecticut.

Gain (loss) on Sale of Real Estate

During the nine months ended September 30, 2017, we recognized a gain on the sale associated with the partial sale of the property at 102 Greene Street ($4.9 million). During the nine months ended September 30, 2016, we recognized a loss on the sale of 7 International Drive, Westchester County, NY ($6.9 million).

Liquidity and Capital Resources

On January 25, 2007, we were acquired by SL Green. See Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" in SL Green and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2016 for a complete discussion of additional sources of liquidity available to us due to our indirect ownership by SL Green.

We currently expect that our principal sources of funds to meet our short-term and long-term liquidity requirements for working capital, acquisitions, development or redevelopment of properties, tenant improvements, leasing costs, repurchases or repayments of outstanding indebtedness (which may include exchangeable debt) and for debt and preferred equity investments will include:

(1) Cash flow from operations;

(2) Cash on hand;

(3) Borrowings under the 2012 credit facility;

(4) Other forms of secured or unsecured financing;

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

(6) Proceeds from debt offerings by us.

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.

We believe that our sources of working capital, specifically our cash flow from operations and SL Green's liquidity are adequate for us to meet our short-term and long-term liquidity requirements for the foreseeable future.

Cash Flows

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

Cash and cash equivalents were $36.0 million and $66.2 million at September 30, 2017 and 2016, respectively, representing a decrease of $30.2 million. The decrease was a result of the following changes in cash flows (in thousands):

	2017			2016			Increase (Decrease)
Net cash provided by operating activities	$	286,772		$	303,483		$	(16,711	)
Net cash (used in) provided by investing activities	$	(129,936	)	$	64,084		$	(194,020	)
Net cash used in financing activities	$	(180,752	)	$	(351,397	)	$	170,645

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 make distributions to SL Green. At September 30, 2017, our operating portfolio was 93.2% occupied. Our debt and preferred equity 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.

31

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

Additions to land, buildings and improvements	$	(14,817	)
Escrowed cash—capital improvements/acquisition deposits/deferred purchase price	5,132
Investments in unconsolidated joint ventures	24,877
Distributions in excess of cumulative earnings from unconsolidated joint ventures	48,010
Net proceeds from disposition of real estate/joint venture interest	71,269
Other investments	41,719
Origination of debt and preferred equity investments	(380,635		)
Repayments or redemption of debt and preferred equity investments	10,425
Decrease in net cash provided by investing activities	$	(194,020	)

Funds spent on capital expenditures, which comprise building and tenant improvements, increased from $82.9 million for the nine months ended September 30, 2016 to $97.7 million for the nine months ended September 30, 2017, relating primarily to increased costs incurred in connection with the redevelopment of properties.

We generally fund our investment activity through the sale of real estate, property-level financing, our 2012 credit facility, our MRA facilities, and senior unsecured notes. During the nine months ended September 30, 2017, when compared to the nine months ended September 30, 2016, we used cash for the following financing activities (in thousands):

Proceeds from mortgages and other loans payable	$	249,617
Repayments of mortgages and other loans payable	119,165
Proceeds from revolving credit facility and senior unsecured notes	187,500
Repayments of revolving credit facility and senior unsecured notes	1,091,808
Distributions to noncontrolling interests in other partnerships	(43,251		)
Contributions from common unitholder	(1,815,757		)
Distributions to common and preferred unitholders	424,159
Other obligations related to loan participations	(42,413		)

2012 Credit Facility

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

ROP, SL Green, and the Operating Partnership are all borrowers jointly and severally obligated under the 2012 credit facility. None of SL Green's other subsidiaries are obligors under the 2012 credit facility.

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

32

Restrictive Covenants

The terms of the 2012 credit facility, as amended, and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, SL Green's 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 SL Green will not during any time when a default is continuing, make distributions with respect to SL Green's common stock or other equity interests, except to enable SL Green to continue to qualify as a REIT for Federal income tax purposes. As of September 30, 2017 and 2016, we were in compliance with all such covenants.

Interest Rate Risk

We are exposed to changes in interest rates primarily from our variable rate debt. Our exposure to interest rate fluctuations are managed through either the use of interest rate derivative instruments and/or through our variable rate debt and preferred equity investments. A hypothetical 100 basis point increase in interest rates along the entire interest rate curve for 2017 would decrease our annual interest cost, net of interest income from variable rate debt and preferred equity investments, by approximately $3.7 million. At September 30, 2017, 59.9% of our $2.0 billion debt and preferred equity portfolio is indexed to LIBOR.

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

Our long-term debt of $2.3 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 as of September 30, 2017 bore interest based on a spread of LIBOR plus 125 basis points to LIBOR plus 313 basis points.

Contractual Obligations

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

Off-Balance Sheet Arrangements

We have off-balance sheet investments, including debt and preferred equity investments. These investments all have varying ownership structures. Our off-balance sheet arrangements are discussed in Note 5, "Debt and Preferred Equity Investments," in the accompanying consolidated financial statements.

Capital Expenditures

We estimate that for the remainder of the year ending December 31, 2017, we expect to incur $24.2 million of recurring capital expenditures and $7.4 million of development or redevelopment expenditures, net of loan reserves, (including tenant improvements and leasing commissions) on existing consolidated properties. 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 debt issuances.

Insurance

ROP is insured through a program administered by SL Green. SL Green maintains “all-risk” property and rental value coverage (including coverage regarding the perils of flood, earthquake and terrorism, excluding nuclear, biological, chemical, and radiological terrorism ("NBCR")), within three property insurance programs and liability insurance. Management believes the policy specifications and insured limits are appropriate given the relative risk of loss, the cost of the coverage, and industry practice. Separate property and liability coverage may be purchased on a stand-alone basis for certain assets.

On January 12, 2015, the Terrorism Risk Insurance Program Reauthorization and Extension Act of 2007 ("TRIPRA") (formerly the Terrorism Risk Insurance Act) was reauthorized until December 31, 2020 pursuant to the Terrorism Insurance Program Reauthorization and Extension Act of 2015. The TRIPRA extends the federal Terrorism Insurance Program that requires insurance companies to offer terrorism coverage and provides for compensation for insured losses resulting from acts of certified terrorism, subject to the current program trigger of $120.0 million, which will increase by $20.0 million per annum, commencing December 31,

33

2015 (Trigger). Coinsurance under TRIPRA is 16%, increasing 1% per annum, as of December 31, 2015 (Coinsurance). There are no assurances TRIPRA will be further extended.

In October 2006, SL Green formed a wholly-owned taxable REIT subsidiary, Belmont Insurance Company, or Belmont, to act as a captive insurance company and as one of the elements of our overall insurance program. Belmont is a subsidiary of SL Green. Belmont was formed in an effort to, among other reasons, mitigate fluctuations in the insurance marketplace. Belmont is licensed in New York to write Terrorism, NBCR (nuclear, biological, chemical, and radiological), General Liability, Environmental Liability and D&O coverage.

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

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

We obtained insurance coverage through an insurance program administered by SL Green. In connection with this program, we incurred insurance expense of approximately $1.3 million and $4.1 million for the three and nine months ended September 30, 2017. We incurred insurance expense of approximately $1.5 million and $4.4 million for the three and nine months ended September 30, 2016.

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.

Accounting Standards Updates

The Accounting Standards Updates are discussed in Note 2, "Significant Accounting Policies-Accounting Standards Updates" in the accompanying consolidated financial statements.

Forward-Looking Information

• risks of real estate acquisitions, dispositions, developments and redevelopment, including the cost of construction delays and cost overruns;

• risks relating to debt and preferred equity investments;

• availability and creditworthiness of prospective tenants and borrowers;

• bankruptcy or insolvency of a major tenant or a significant number of smaller tenants;

• adverse changes in the real estate markets, including reduced demand for office space, increasing vacancy, and increasing availability of sublease space;

• unanticipated increases in financing and other costs, including a rise in interest rates;

• our ability to comply with financial covenants in our debt instruments;

• our ability to maintain its status as a REIT;

• legislative, regulatory and/or safety requirements adversely affecting REITs and the real estate business including costs of compliance with the Americans with Disabilities Act, the Fair Housing Act and other similar laws and regulations.

Other factors and risks to our business, many of which are beyond our control, are described in other sections of this report and in our other filings with the SEC. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of future events, new information or otherwise.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

For quantitative and qualitative disclosure about market risk, see Item 2, "Management's Discussion and Analysis of Financial Condition and Results of Operation-Interest Rate Risk" in this Quarterly Report on Form 10-Q for the three and nine months ended September 30, 2017 and Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in our Annual Report on Form 10-K for the year ended December 31, 2016. Our exposures to market risk have not changed materially since December 31, 2016.

ITEM 4.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain 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 our management, including the principal executive officer and principal financial officer of our general partner, 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 ROP to disclose material information otherwise required to be set forth in our periodic reports.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including the President and Treasurer of our general partner, 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 President and Treasurer of our general partner concluded that our disclosure controls and procedures were effective to give reasonable assurances to the timely collection, evaluation and disclosure of information relating to ROP 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

Organization and Basis of Presentation

Organization and Basis of Presentation

Reckson Operating Partnership, L.P., or ROP, commenced operations on June 2, 1995. The sole general partner of ROP is Wyoming Acquisition GP LLC., or WAGP, a wholly-owned subsidiary of SL Green Operating Partnership, L.P., or the Operating Partnership. The sole limited partner of ROP is the Operating Partnership. The Operating Partnership is 95.55% owned by SL Green Realty Corp., or SL Green, as of September 30, 2017. SL Green is a self-administered and self-managed real estate investment trust, and is the sole managing general partner of the Operating Partnership. Unless the context requires otherwise, all references to "we," "our," "us" and the "Company" means ROP and all entities owned or controlled by ROP.

ROP is engaged in the acquisition, ownership, management and operation of commercial and residential real estate properties, principally office properties, and also owns land for future development, located in New York City, Westchester County, Connecticut and New Jersey, which collectively is also known as the New York Metropolitan area.

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

Location	Type	Number of Properties	Approximate Square Feet (unaudited)	Weighted Average Occupancy(1) (unaudited)
Commercial:
Manhattan	Office	16	8,463,245	95.7	%
	Retail(2)(3)	5	364,816	98.0	%
	Fee Interest	1	176,530	100.0	%
		22	9,004,591	95.9	%
Suburban	Office(4)	15	2,746,000	84.6	%
	Retail	1	52,000	100.0	%
		16	2,798,000	84.9	%
Total commercial properties		38	11,802,591	93.2	%
Residential:
Manhattan	Residential(2)	—	222,855	88.0	%
Total portfolio		38	12,025,446	93.2	%

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

(2) As of September 30, 2017, we owned a building at 315 West 33rd Street, also known as The Olivia, that was comprised of approximately 270,132 square feet (unaudited) of retail space and approximately 222,855 square feet (unaudited) of residential space. For the purpose of this report, we have included this building in the number of retail properties we own. However, we have included only the retail square footage in the retail approximate square footage, and have listed the balance of the square footage as residential square footage.

(3) Includes two unconsolidated joint venture retail properties at 131-137 Spring Street comprised of approximately 68,342 square feet.

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

As of September 30, 2017, we held debt and preferred equity investments with a book value of $2.2 billion, including $0.1 billion of debt and preferred equity investments and other financing receivables that are included in other balance sheet line items other than the Debt and Preferred Equity Investments line item.

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 at September 30, 2017 and the results of operations for the periods presented have been included. The operating results for the period presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. These financial statements should be read in conjunction with the financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2016.

The consolidated balance sheet at December 31, 2016 has been derived from the audited financial statements as of that date but do not include all the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Principles of Consolidation

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

We consolidate a variable interest entity, or VIE, in which we are considered the primary beneficiary. The primary beneficiary is the entity that has (i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE.

Investment in Commercial Real Estate Properties

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted) to be generated by the property is less than the carrying value of the property. To the extent impairment has occurred, the loss will be measured as the excess of the carrying amount of the property over the calculated fair value of the property. We also evaluate our real estate properties for potential impairment when a real estate property has been classified as held for sale. Real estate assets held for sale are valued at the lower of either their carrying value or fair value less costs to sell. We do not believe that there were any indicators of impairment at any of our consolidated properties at September 30, 2017. We recorded $0.4 million depreciable real estate reserves for the three months ended September 30, 2017, and aggregate depreciable real estate reserves of $85.7 million for the nine months ended September 30, 2017. See Note 4, "Property Dispositions".

We allocate the purchase price of real estate to land and building (inclusive of tenant improvements) and, if determined to be material, intangibles, such as the value of above- and below-market leases and origination costs associated with the in-place leases. We depreciate the amount allocated to building (inclusive of tenant improvements) over their estimated useful lives, which generally range from three to 40 years. We amortize the amount allocated to the above- and below-market leases over the remaining term of the associated lease, which generally range from one to 14 years, and record it as either an increase (in the case of below-market leases) or a decrease (in the case of above-market leases) to rental income. We amortize the amount allocated to the values associated with in-place leases over the expected term of the associated lease, which generally ranges from one to 14 years. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off. The tenant improvements and origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). We assess fair value of the leases based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and market/economic conditions that may affect the property. To the extent acquired leases contain fixed rate renewal options that are below-market and determined to be material, we amortize such below-market lease value into rental income over the renewal period.

We recognized $4.3 million and $12.7 million of rental revenue for the three and nine months ended September 30, 2017, and $8.1 million and $15.9 million of rental revenue for the three and nine months ended September 30, 2016, for the amortization of aggregate below-market leases in excess of above-market leases and a reduction in lease origination costs, resulting from the allocation of the purchase price of the applicable properties.

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

	September 30, 2017			December 31, 2016
Identified intangible assets (included in other assets):
Gross amount	$	285,271		$	311,830
Accumulated amortization	(241,949		)	(253,064		)
Net(1)	$	43,322		$	58,766
Identified intangible liabilities (included in deferred revenue):
Gross amount	$	508,373		$	524,793
Accumulated amortization	(372,190		)	(368,738		)
Net(1)	$	136,183		$	156,055

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

Fair Value Measurements

See Note 12, "Fair Value Measurements."

Investments in Unconsolidated Joint Ventures

We assess our investments in unconsolidated joint ventures for recoverability, and if it is determined that a loss in value of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments for impairment based on the joint ventures' projected discounted cash flows. We do not believe that the values of any of our equity investments were impaired at September 30, 2017.

Reserve for Possible Credit Losses

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

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the net fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during the three and nine months ended September 30, 2017 and 2016.

Income Taxes

ROP is a disregarded entity of SL Green Operating Partnership, L.P. for federal income tax purposes, and, as a result, all income and losses of ROP are considered income and losses of SL Green Operating Partnership, L. P. No provision has been made for income taxes in the consolidated financial statements since such taxes, if any, are the responsibility of the individual partners of SL Green Operating Partnership, L.P.

Shares Contributed by Parent Company

We present shares of SL Green common stock as a contra-equity account in 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 New York City. See Note 5, "Debt and Preferred Equity Investments." We perform ongoing credit evaluations of our tenants and require most tenants to provide security deposits or letters of credit. Though these security deposits and letters of credit are insufficient to meet the total value of a tenant's lease obligation, they are a measure of good faith and a source of funds to offset the economic costs associated with lost revenue and the costs associated with re-tenanting a space.

The properties in our real estate portfolio are primarily located in Manhattan. We also have properties located in Brooklyn, Westchester County, Connecticut and New Jersey. The tenants located in our buildings operate in various industries. No tenant in our portfolio accounted for more than 5.0% of our share of annualized cash rent, including our share of joint venture annualized rent, at September 30, 2017. For the three months ended September 30, 2017, 13.8%, 9.1%, 7.4%, 7.2%, 7.1%, 6.3%, 6.1%, and 5.9% of our share of cash rent, including our share of joint venture annualized rent was attributable to 1185 Avenue of the Americas, 625 Madison Avenue, 919 Third Avenue, 750 Third Avenue, 810 Seventh Avenue, 555 West 57th Street, 125 Park Avenue. and 1350 Avenue of the Americas, respectively. Our share of annualized cash rent for all other properties was below 5.0%.

Reclassification

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

Accounting Standards Updates

In August 2017, the FASB issued Accounting Standards Update (ASU) No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. The amendments in the new standard will permit more flexibility in hedging interest rate risk for both variable rate and fixed rate financial instruments. The standard will also enhance the presentation of hedge results in the financial statements. The guidance is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. The Company has not yet adopted the guidance, and does not expect a material impact on the Company’s consolidated financial statements when the new standard is implemented.

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

In January, 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The guidance clarifies the definition of a business and provides guidance to assist with determining whether transactions should be accounted for as acquisitions of assets or businesses. The main provision is that an acquiree is not a business if substantially all of the fair value of the gross assets is concentrated in a single identifiable asset or group of assets. The Company adopted the guidance on the issuance date effective January 5, 2017. The Company expects that most of our real estate acquisitions will be considered asset acquisitions under the new guidance and that transaction costs will be capitalized to the investment basis which is then subject to a purchase price allocation based on relative fair value.

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

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

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

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

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

In January 2016, the FASB issued ASU 2016-01 (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and to record changes in instruments-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income. The guidance is effective for fiscal years beginning after December 15, 2017, and for interim periods therein. The Company has not yet adopted this new guidance and is currently evaluating the impact of adopting this new accounting standard on the Company’s consolidated financial statements.

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

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

Properties Held for Sale and Property Dispositions

Properties Held for Sale

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

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

Property Dispositions

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

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

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

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

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

(1) Carrying value is net of discounts, premiums, original issue discounts and deferred origination fees.

(2) Represents contractual maturity, excluding any unexercised extension options.

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

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

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

(6) This loan was repaid in June 2017.

(7) This loan was repaid in March 2017.

(8) This loan was extended in October 2017.

(9) This loan was extended in January 2017.

(10) This loan was extended in September 2017.

(11) $66.1 million of outstanding principal was syndicated in February 2017.

(12) This loan was repaid in September 2017.

(13) This loan was contributed to a joint venture in May 2017.

(14) This loan was repaid in January 2017.

Preferred Equity Investments

As of September 30, 2017 and December 31, 2016, we held the following preferred equity investments with an aggregate weighted average current yield of 6.98% at September 30, 2017 (in thousands):

Type	September 30, 2017 Future Funding Obligations		September 30, 2017 Senior Financing		September 30, 2017 Carrying Value (1)		December 31, 2016 Carrying Value (1)		Mandatory Redemption (2)

Preferred Equity(5)	—		—		—		37,893
Total	$	—	$	272,000	$	143,980	$	47,875

(1) Carrying value is net of deferred origination fees.

(2) Represents contractual maturity, excluding any unexercised extension options.

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

(4) This investment was redeemed in May 2017.

(5) This investment was redeemed in April 2017.

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

We have determined that we have one portfolio segment of financing receivables at September 30, 2017 and 2016 comprising commercial real estate which is primarily recorded in debt and preferred equity investments. Included in other assets is an additional amount of financing receivables totaling $94.8 million and $144.5 million at September 30, 2017 and December 31, 2016, respectively. No financing receivables were 90 days past due at September 30, 2017.

Investments in Unconsolidated Joint Ventures

We have investments in several real estate joint ventures with various partners. As of September 30, 2017, none of our investments in unconsolidated joint ventures are VIEs. The table below provides general information on each of our joint ventures as of September 30, 2017:

Mezzanine Loan (3)	Private Investors	33.33%	33.33%	—	May 2017	15,000

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

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

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

Acquisition, Development and Construction Arrangements

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

Loan Type	September 30, 2017		December 31, 2016		Maturity Date

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

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

Joint Venture Mortgages and Other Loans Payable

We generally finance our joint ventures with non-recourse debt. In certain cases we may provide guarantees or master leases for tenant space, which terminate upon the satisfaction of specified circumstances or repayment of the underlying loans. The first mortgage notes and other loans payable collateralized by the respective joint venture properties and assignment of leases at September 30, 2017 and December 31, 2016, respectively, are as follows (amounts in thousands):

(1) Effective weighted average interest rate for the quarter ended September 30, 2017.

(2) We own a 51.0% controlling interest in the consolidated joint venture that is the borrower on this loan.

At September 30, 2017 and December 31, 2016, the gross book value of the properties and debt and preferred equity investments collateralizing the mortgages and other loans payable, not including assets held for sale, was approximately $2.5 billion and $1.7 billion, respectively.

Master Repurchase Agreements

The Company has entered into two Master Repurchase Agreements, or MRAs, known as the 2016 MRA and 2017 MRA, which provide us with the ability to sell certain debt investments with a simultaneous agreement to repurchase the same at a certain date or on demand. We seek to mitigate risks associated with our repurchase agreement by managing the credit quality of our assets, early repayments, interest rate volatility, liquidity, and market value. The margin call provisions under our repurchase facilities permit valuation adjustments based on capital markets activity, and are not limited to collateral-specific credit marks. To monitor credit risk associated with our debt investments, our asset management team regularly reviews our investment portfolio and is in contact with our borrowers in order to monitor the collateral and enforce our rights as necessary. The risk associated with potential margin calls is further mitigated by our ability to recollateralize the facility with additional assets from our portfolio of debt investments, our ability to satisfy margin calls with cash or cash equivalents and our access to additional liquidity through the 2012 credit facility, as defined below.

In June 2017, we entered into the 2017 MRA, with a maximum facility capacity of $300.0 million. The facility bears interest on a floating rate basis at a spread to 30-day LIBOR based on the pledged collateral and advance rate and has an initial one year term, with twoone year extension options. At September 30, 2017, the facility had a carrying value of $(1.1) million, representing deferred financing costs presented within other liabilities.

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

2012 Credit Facility

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

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

At September 30, 2017, the applicable spread was 125 basis points for the revolving credit facility and 140 basis points for the term loan facility. At September 30, 2017, the effective interest rate was 2.49% for the revolving credit facility and 2.63% for the term loan facility. We are required to pay quarterly in arrears a 12.5 to 30 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. As of September 30, 2017, the facility fee was 25 basis points.

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

ROP, SL Green, and the Operating Partnership are all borrowers jointly and severally obligated under the 2012 credit facility. None of SL Green's other subsidiaries are obligors under the 2012 credit facility.

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

Restrictive Covenants

The terms of the 2012 credit facility, as amended, and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, SL Green's 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 SL Green will not during any time when a default is continuing, make distributions with respect to SL Green's common stock or other equity interests, except to enable SL Green to continue to qualify as a REIT for Federal income tax purposes. As of September 30, 2017 and 2016, we were in compliance with all such covenants.

Preferred Units

Through a consolidated subsidiary, we have authorized up to 109,1613.50% Series A Preferred Units of limited partnership interest, or the Greene Series A Preferred Units, with a liquidation preference of $1,000.00 per unit. In August 2015, the Company issued 109,161 Greene Series A Preferred Units in conjunction with an acquisition. The Greene Series A Preferred unitholders receive annual dividends of $35.00 per unit paid on a quarterly basis and dividends are cumulative, subject to certain provisions. The Greene Series A Preferred Units can be redeemed at any time, at the option of the unitholder, either for cash or are convertible on a one-for-one basis, into the Series B Preferred Units of limited partnership interest, or the Greene Series B Preferred Units. The Greene Series B Preferred Units can be converted at any time, at the option of the unitholder, into a number of common stock equal to 6.71348 shares of SL Green common stock for each Greene Series B Preferred Unit. As of September 30, 2017, no Greene Series B Preferred Units have been issued.

ASC 815 Derivatives and Hedging requires bifurcation of certain embedded derivative instruments, such as conversion features in convertible equity instruments, and their measurement at fair value for accounting purposes. The conversion feature embedded in the Subsidiary Series A Preferred Units was evaluated, and it was determined that the conversion feature should be bifurcated from its host instrument and accounted for as a freestanding derivative. The derivative is reported as a derivative liability in accrued interest and other liabilities on the accompanying consolidated balance sheet and is adjusted to its fair value at each reporting date, with a corresponding adjustment to interest expense, net of interest income. The embedded derivative for the Subsidiary Series A Preferred Units was initially recorded at a fair value of zero on July 22, 2015, the date of issuance. At December 31, 2016, the carrying amount of the derivative was adjusted to its fair value of zero, with a corresponding adjustment to preferred units and interest expense, net of interest income. At September 30, 2017, the carrying amount and fair value of the derivative remained at zero.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

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

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

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

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

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

The following table provides the carrying value and fair value of these financial instruments as of September 30, 2017 and December 31, 2016 (in thousands):

	September 30, 2017				December 31, 2016
	Carrying Value (1)		Fair Value		Carrying Value (1)		Fair Value

(1) Amounts exclude net deferred financing costs.

(2) At September 30, 2017, debt and preferred equity investments had an estimated fair value ranging between $2.0 billion and $2.2 billion. At December 31, 2016, debt and preferred equity investments had an estimated fair value ranging between $1.6 billion and $1.8 billion.

Disclosure about fair value of financial instruments was based on pertinent information available to us as of September 30, 2017 and December 31, 2016. 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Financial Instruments: Derivatives and Hedging

Financial Instruments: Derivatives and Hedging

In the normal course of business, we use a variety of commonly used derivative instruments, such as interest rate swaps, caps, collar and floors, to manage, or hedge interest rate risk. We hedge our exposure to variability in future cash flows for forecasted transactions in addition to anticipated future interest payments on existing debt. We recognize all derivatives on the balance sheets at fair value. Derivatives that are not hedges are adjusted to fair value through earnings. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedge asset, liability, or firm commitment through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. Reported net income and equity may increase or decrease prospectively, depending on future levels of interest rates and other variables affecting the fair values of derivative instruments and hedged items, but will have no effect on cash flows. Currently, all of our designated derivative instruments are effective hedging instruments. As of September 30, 2017, the Company had not designated any interest rate swap agreements on any debt investment.

Gains and losses on terminated hedges are included in accumulated other comprehensive loss, and are recognized into earnings over the term of the related senior unsecured notes. As of September 30, 2017 and December 31, 2016, the deferred net losses from these terminated hedges, which are included in accumulated other comprehensive loss relating to net unrealized loss on derivative instruments, was approximately $1.3 million and $1.6 million, respectively.

Over time, the realized and unrealized gains and losses held in accumulated other comprehensive loss will be reclassified into earnings as an adjustment to interest expense in the same periods in which the hedged interest payments affect earnings. We estimate that $0.4 million of the current balance held in accumulated other comprehensive loss will be reclassified into interest expense within the next 12 months.

The following table presents the effect of our derivative financial instruments that are designated and qualify as hedging instruments on the consolidated statements of operations for the three months ended September 30, 2017 and 2016, respectively (in thousands):

Segment Reporting [Abstract]

Segment Information

Segment Information

We are engaged in acquiring, owning, managing and leasing commercial properties in Manhattan, Brooklyn, Westchester County, Connecticut and New Jersey and have two reportable segments, real estate and debt and preferred equity investments. We evaluate real estate performance and allocate resources based on earnings contribution to income from continuing operations.

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

Selected consolidated results of operations for the three and nine months ended September 30, 2017 and 2016, and selected asset information as of September 30, 2017 and December 31, 2016, regarding our operating segments are as follows (in thousands):

Income from continuing operations represents total revenues less total expenses for the real estate segment and total investment income less allocated interest expense for the debt and preferred equity segment. Interest costs for the debt and preferred equity segment includes actual costs incurred for borrowings on the 2016 MRA and 2017 MRA. Interest is imputed on the investments that do not collateralize the 2016 MRA or 2017 MRA using our corporate borrowing cost. We also allocate loan loss reserves, net of recoveries, and transaction related costs to the debt and preferred equity segment. We do not allocate marketing, general and administrative expenses to the debt and preferred equity segment since the use of personnel and resources is dependent on transaction volume between the two segments and varies period over period. In addition, we base performance on the individual segments prior to allocating marketing, general and administrative expenses. For the three and nine months ended September 30, 2017, and 2016, marketing, general and administrative expenses totaled $0.1 million, $0.2 million, $0.3 million, and $0.6 million, respectively. All other expenses, except interest, relate entirely to the real estate assets.

There were no transactions between the above two segments.

Accounting Policies [Abstract]

Principles of Consolidation

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

Investment in Commercial Real Estate Properties

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted) to be generated by the property is less than the carrying value of the property. To the extent impairment has occurred, the loss will be measured as the excess of the carrying amount of the property over the calculated fair value of the property. We also evaluate our real estate properties for potential impairment when a real estate property has been classified as held for sale. Real estate assets held for sale are valued at the lower of either their carrying value or fair value less costs to sell. We do not believe that there were any indicators of impairment at any of our consolidated properties at September 30, 2017. We recorded $0.4 million depreciable real estate reserves for the three months ended September 30, 2017, and aggregate depreciable real estate reserves of $85.7 million for the nine months ended September 30, 2017. See Note 4, "Property Dispositions".

We allocate the purchase price of real estate to land and building (inclusive of tenant improvements) and, if determined to be material, intangibles, such as the value of above- and below-market leases and origination costs associated with the in-place leases. We depreciate the amount allocated to building (inclusive of tenant improvements) over their estimated useful lives, which generally range from three to 40 years. We amortize the amount allocated to the above- and below-market leases over the remaining term of the associated lease, which generally range from one to 14 years, and record it as either an increase (in the case of below-market leases) or a decrease (in the case of above-market leases) to rental income. We amortize the amount allocated to the values associated with in-place leases over the expected term of the associated lease, which generally ranges from one to 14 years. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off. The tenant improvements and origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). We assess fair value of the leases based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and market/economic conditions that may affect the property. To the extent acquired leases contain fixed rate renewal options that are below-market and determined to be material, we amortize such below-market lease value into rental income over the renewal period.

Investments in Unconsolidated Joint Ventures

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.

Reserve for Possible Credit Losses

Reserve for Possible Credit Losses

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

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the net fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of our investment, we will adjust our reserves accordingly.

Income Taxes

Income Taxes

ROP is a disregarded entity of SL Green Operating Partnership, L.P. for federal income tax purposes, and, as a result, all income and losses of ROP are considered income and losses of SL Green Operating Partnership, L. P. No provision has been made for income taxes in the consolidated financial statements since such taxes, if any, are the responsibility of the individual partners of SL Green Operating Partnership, L.P.

Shares Contributed by Parent Company

Shares Contributed by Parent Company

We present shares of SL Green common stock as a contra-equity account in our financial statements.

Use of Estimates

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

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash investments, debt and preferred equity investments and accounts receivable. We place our cash investments with high quality financial institutions. The collateral securing our debt and preferred equity investments is located in New York City. See Note 5, "Debt and Preferred Equity Investments." We perform ongoing credit evaluations of our tenants and require most tenants to provide security deposits or letters of credit. Though these security deposits and letters of credit are insufficient to meet the total value of a tenant's lease obligation, they are a measure of good faith and a source of funds to offset the economic costs associated with lost revenue and the costs associated with re-tenanting a space.

The properties in our real estate portfolio are primarily located in Manhattan. We also have properties located in Brooklyn, Westchester County, Connecticut and New Jersey. The tenants located in our buildings operate in various industries.

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

Accounting Standards Updates

Accounting Standards Updates

In August 2017, the FASB issued Accounting Standards Update (ASU) No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities. The amendments in the new standard will permit more flexibility in hedging interest rate risk for both variable rate and fixed rate financial instruments. The standard will also enhance the presentation of hedge results in the financial statements. The guidance is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. The Company has not yet adopted the guidance, and does not expect a material impact on the Company’s consolidated financial statements when the new standard is implemented.

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

In January, 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The guidance clarifies the definition of a business and provides guidance to assist with determining whether transactions should be accounted for as acquisitions of assets or businesses. The main provision is that an acquiree is not a business if substantially all of the fair value of the gross assets is concentrated in a single identifiable asset or group of assets. The Company adopted the guidance on the issuance date effective January 5, 2017. The Company expects that most of our real estate acquisitions will be considered asset acquisitions under the new guidance and that transaction costs will be capitalized to the investment basis which is then subject to a purchase price allocation based on relative fair value.

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

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

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

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

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

In January 2016, the FASB issued ASU 2016-01 (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and to record changes in instruments-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income. The guidance is effective for fiscal years beginning after December 15, 2017, and for interim periods therein. The Company has not yet adopted this new guidance and is currently evaluating the impact of adopting this new accounting standard on the Company’s consolidated financial statements.

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

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

Fair Value Measurements

Fair Value Measurements

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

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

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

The 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.

(3) These loans were purchased at par in April and May 2017 and were in maturity default at the time of acquisition. At the time the loans were purchased, the Company expected to collect all contractually required payments, including interest. In August 2017, the Company determined that it was probable that the loans would not be repaid in full and therefore, the loans were put on non-accrual status.

The loans had an outstanding balance including accrued interest of $259.3 million at the time that they were put on non-accrual status.

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

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

(3) In February 2016, we closed on the sale of 885 Third Avenue and retained a preferred equity position in the property. The sale did not meet the criteria for sale accounting under the full accrual method in ASC 360-20, Property, Plant and Equipment - Real Estate Sales.
