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 94.90% owned by SL Green Realty Corp., or SL Green, as of September 30, 2018. 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.

We are engaged in the acquisition, ownership, management and operation of commercial and residential real estate properties, principally office properties, and also own land for future development in the New York metropolitan area.

As of September 30, 2018, we owned the following interests in properties in the New York metropolitan area, primarily in midtown Manhattan. Our investments located outside of Manhattan are referred to as the Suburban properties:

Location	Type	Number of Properties	Approximate Square Feet (unaudited)	Weighted Average Occupancy(1) (unaudited)
Commercial:
Manhattan	Office(2)(3)	15	8,303,245	93.6	%
	Retail(4)(5)	5	364,816	98.9	%
	Development/Redevelopment	1	160,000	—	%
		21	8,828,061	92.2	%
Suburban	Office	6	1,432,400	93.8	%
	Retail	1	52,000	100.0	%
		7	1,484,400	94.0	%
Total commercial properties		28	10,312,461	92.4	%
Residential:
Manhattan	Residential(4)	—	222,855	95.8	%
Total portfolio		28	10,535,316	92.5	%

(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) Includes one unconsolidated joint venture property at 919 Third Avenue comprised of approximately 1,454,000 square feet.

(3) Includes one unconsolidated tenancy-in-common (or "TIC") interest at 2 Herald Square, which is under contract for sale as of September 30, 2018.

(4) As of September 30, 2018, we owned a building at 315 West 33rd Street, also known as The Olivia, that was comprised of approximately 270,132 square feet (unaudited) of retail space and approximately 222,855 square feet (unaudited) of residential space. For the purpose of this report, we have included this building in the number of retail properties we own. However, we have included only the retail square footage in the retail approximate square footage, and have listed the balance of the square footage as residential square footage.

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

As of September 30, 2018, we held debt and preferred equity investments with a book value of $2.0 billion.

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, 2018 and the results of operations for the periods presented have been included. The operating results for the period presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. These financial statements should be read in conjunction with the financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2017.

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

2. Significant Accounting Policies

Principles of Consolidation

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

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

Investment in Commercial Real Estate Properties

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

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted) to be generated by the property is less than the carrying value of the property. To the extent impairment has occurred, the loss will be measured as the excess of the carrying amount of the property over the calculated fair value of the property. We also evaluate our real estate properties for impairment when a property has been classified as held for sale. Real estate assets held for sale are valued at the lower of their carrying value or fair value less costs to sell.

We recognized $1.3 million and $5.5 million of rental revenue for the three and nine months ended September 30, 2018, respectively, and $4.3 million and $12.7 million for the three and nine months ended September 30, 2017, respectively, for the amortization of aggregate below-market leases in excess of above-market leases and a reduction in lease origination costs, resulting from the allocation of the purchase price of the applicable properties.

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, 2018 and December 31, 2017 (in thousands):

	September 30, 2018			December 31, 2017

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, 2018.

Reserve for Possible Credit Losses

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

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during the three and nine months ended September 30, 2018 and 2017.

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

Income Taxes

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 within general partner capital in our consolidated financial statements.

Use of Estimates

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

Concentrations of Credit Risk

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

We perform ongoing credit evaluations of our tenants and require most tenants to provide security deposits or letters of credit. Though these security deposits and letters of credit are insufficient to meet the total value of a tenant's lease obligation,

they are a measure of good faith and a source of funds to offset the economic costs associated with lost revenue and the costs associated with re-tenanting a space. The properties in our real estate portfolio are located in the New York metropolitan area. The tenants located in our buildings operate in various industries. 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, 2018. For the three months ended September 30, 2018, 14.7%, 11.0%, 8.7%, 8.4%, 8.2%, 7.6%, 7.4%, 7.1% and 5.8% of our annualized cash 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, 1350 Avenue of the Americas, and 711 Third Avenue, respectively. 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 2018, The Securities and Exchange Commission adopted a final rule that eliminated or amended disclosure requirements that were redundant or outdated in light of changes in its requirements, generally accepted accounting principles, or changes in the business environment. The commission also referred certain disclosure requirements to the Financial Accounting Standards Board for potential incorporation into generally accepted accounting principles. The Company assessed the impact of this rule and determined that the changes resulted in clarification or expansion of existing requirements. The Company adopted the rule on November 5, 2018 and it did not have a material impact on the Company’s consolidated financial statements.

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

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

In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments- Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. These amendments provide additional guidance related to equity securities without a readily determinable fair value, forward contracts and options purchased on those equity securities and fair value option liabilities. The Company adopted the guidance on July 1, 2018, and it did not have a material impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities, and in July 2018, the FASB issued ASU No. 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. The amendments in the new standards will permit more flexibility in hedging interest rate risk for both variable rate and fixed rate financial instruments. The standards will also enhance the presentation of hedge results in the financial statements. The guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. The Company has not yet adopted the guidance, and does not expect a material impact on the Company’s consolidated financial statements when the new standards are implemented.

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

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

In February 2016, the FASB issued ASU No. 2016-02, Leases, and in July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases and ASU No. 2018-11, Leases (Topic 842): Targeted Improvements. This guidance requires lessees to recognize lease assets and lease liabilities for those leases classified as operating leases under the previous standard. Depending on the lease classification, lessees will recognize expense based on the effective interest method for finance leases or on a straight-line basis for operating leases. The accounting applied by a lessor, inclusive of the effect of a practical expedient offered in ASU No. 2018-11 that allows lessors to not separate non-lease components from the related lease components under certain conditions, which the Company expects most of its leases to qualify for and to adopt, is largely unchanged from that applied under the previous standard. However, the Company will apply this guidance to the ground leases under which the Company is lessee. The Company is required to record a liability for the obligation to make payments under the lease and an asset for the right to use the underlying asset during the lease term and will also apply the new expense recognition requirements given the lease classification. While the Company is continuing to assess all potential impacts of the standard, we expect total liabilities and total assets to increase by $0.1 to $0.2 billion as of the date of adoption. This guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The Company expects to adopt this guidance January 1, 2019 and will apply the modified retrospective approach, and anticipates electing the package of practical expedients that allows an entity to not reassess (i) whether any expired or existing contracts are or contain leases, (ii) lease classification for any expired or existing leases and (iii) initial direct costs for any expired or existing leases.

In January 2016, the FASB issued ASU 2016-01 (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value through earnings, to record changes in instrument-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income, use the exit price notion when measuring an instrument’s fair value for disclosure and to separately present financial assets and liabilities by measurement category and form of instrument on the balance sheet or in the notes to the financial statements. The Company adopted the guidance effective January 1, 2018, and it had no impact on the Company’s consolidated financial statements.

In May 2014, the FASB issued a new comprehensive revenue recognition guidance which requires us to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods and services (ASU 2014-09). The FASB also issued implementation guidance in March 2016, April 2016 and May 2016 - ASU’s 2016-08, 2016-10 and 2016-12, respectively. The Company adopted this guidance on January 1, 2018. Since the Company’s revenue is related to leasing activities, the adoption of this guidance did not have a material impact on the consolidated financial statements. The new guidance is applicable to service contracts with joint ventures for which the Company earns property management fees, leasing commissions and development and construction fees. The adoption of this new guidance did not change the accounting for these fees as the pattern of recognition of revenue does not change with the new guidance. We will continue to recognize revenue over time on these contracts because the customer simultaneously receives and consumes the benefits provided by our performance.

In February 2017, the FASB issued ASU No. 2017-05 to clarify the scope of asset derecognition guidance in Subtopic 610-20, which also provided guidance on accounting for partial sales of nonfinancial assets.  Subtopic 610-20 was issued in May 2014 as part of ASU 2014-09.  The Company adopted this guidance on January 1, 2018, and applied the modified retrospective approach. The Company elected to adopt the practical expedient under ASC 606, Revenue from Contracts with Customers, which allows an entity to apply the guidance only to contracts with non-customers that are open based on ASU 360-20, Real Estate Sales, (i.e. failed sales) as of the adoption date. The adoption had no impact on the consolidated financial statements as the Company had no open contracts based on ASC 360-20 as of December 31, 2017.

3. Property Acquisitions

During the nine months ended September 30, 2018, we did not acquire any properties from a third party.

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

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

At September 30, 2018, all debt and preferred equity investments were performing in accordance with the terms of the relevant investments, with the exception of one mezzanine loan which was in maturity default. The mezzanine note receivable was conveyed in the form of a distribution to SL Green in October 2018.

At December 31, 2017, all debt and preferred equity investments were performing in accordance with the terms of the relevant investments with the exception of a junior mortgage participation acquired in September 2014, which was acquired for zero and has a carrying value of zero, as discussed in subnote 5 of the Debt Investments table above, and our investment in 2 Herald Square, which was purchased in maturity default and was subsequently conveyed to SL Green in the form of a distribution in the first quarter of 2018. In May 2018, SL Green was the successful bidder for the leasehold interest at the foreclosure of the asset and assigned the Company a 49.0% tenancy in common interest in the leasehold interest.

We have determined that we have one portfolio segment of financing receivables at September 30, 2018 and December 31, 2017, 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 $111.5 million and $93.4 million at September 30, 2018 and December 31, 2017, respectively. No financing receivables were 90 days past due at September 30, 2018.

6. Investments in Unconsolidated Joint Ventures

We have investments in several real estate joint ventures with various partners. As of September 30, 2018 and December 31, 2017, none of our investments in unconsolidated joint ventures were VIEs. All of the investments below are voting interest entities. As we do not control the joint ventures listed below, we account for them under the equity method of accounting.

The table below provides general information on each of our joint ventures as of September 30, 2018:

Property	Partner	Ownership Interest(1)	Economic Interest(1)	Unaudited Approximate Square Feet	Acquisition Date(2)	Acquisition Price(2) (in thousands)
919 Third Avenue(3)	New York State Teacher's Retirement System	51.00%	51.00%	1,454,000	January 2007	$	1,256,727
131-137 Spring Street	Invesco Real Estate	20.00%	20.00%	68,342	August 2015	277,750
2 Herald Square(4)	(4)	49.00%	49.00%	369,000	May 2018	266,000

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

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

(3) In January 2018, the partnership agreement for our investment was modified resulting in the Company no longer having a controlling interest in this investment. As a result the investment was deconsolidated as of January 1, 2018. The Company recorded its non-controlling interest at fair value resulting in a $54.9 million fair value adjustment in the consolidated statement of operations. This fair value was allocated to the assets and liabilities, including identified intangibles of the property.

(4) In May 2018, SL Green assigned the Company a 49.0% tenancy-in-common interest in the leasehold interest in 2 Herald Square and entered into an agreement to sell this investment. Consolidation of this investment is not required as such interest does not qualify as a VIE and does not meet the control requirement for consolidation. Accordingly, we account for this investment using the equity method of accounting. We use the equity method of accounting because the shared decision-making involved in a tenancy-in-common interest investment provides us with significant influence on the operating and financial decisions of this investment.

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, 2018 and December 31, 2017, the carrying value for acquisition, development and construction arrangements were as follows (in thousands):

Loan Type	September 30, 2018		December 31, 2017		Maturity Date
Mezzanine Loan(1)	$	—	$	26,716
Mezzanine Loan and Preferred Equity(2)	—		100,000
	$	—	$	126,716

(1) The Company was redeemed on this investment in July 2018.

(2) The mezzanine loan was repaid and the preferred equity interest was redeemed in March 2018.

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 and our ability to satisfy margin calls with cash or cash equivalents.

In June 2017, we entered into the 2017 MRA, with a maximum facility capacity of $300.0 million. In April 2018, we increased the maximum facility capacity to $400.0 million. The facility bears interest on a floating rate basis at a spread to 30-day LIBOR based on the pledged collateral and advance rate and has an initial one year term, with twoone year extension options. In June 2018, we exercised a one year extension option. At September 30, 2018, the facility had an outstanding balance of $299.4 million, net of deferred financing costs.

In July 2016, we entered into the 2016 MRA, with a maximum facility capacity of $300.0 million. In June 2018, we terminated the 2016 MRA. The facility bore interest ranging from 225 and 400 basis points over 30-day LIBOR depending on the pledged collateral and had an initial two-year term, with a one year extension option. Since December 6, 2015, we had 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 was less than $150.0 million.

2017 Credit Facility

In November 2017, the Company, SL Green and the Operating Partnership entered into an amendment to the credit facility, referred to as the 2017 credit facility, that was originally entered into in November 2012, or the 2012 credit facility. The amendment resulted in the Company no longer being a borrower and instead is providing a guarantee of the facility. The 2012 credit facility had a carrying value of $1.2 billion, net of deferred financing costs, as of the amendment date and was removed from our consolidated balance sheet and shown as a non-cash capital contribution. SL Green and the Operating Partnership remain borrowers, jointly and severally obligated, under the 2017 credit facility. As of September 30, 2018, the 2017 credit facility consisted of a $1.5 billion revolving credit facility, a $1.3 billion term loan (or "Term Loan A"), and a $200.0 million term loan (or "Term Loan B") with maturity dates of March 31, 2022, March 31, 2023, and November 21, 2024, respectively. The revolving credit facility has twosix-month as-of-right extension options to March 31, 2023. SL Green and the Operating Partnership also have an option, subject to customary conditions, to increase the capacity of the credit facility to $4.5 billion at any time prior to the maturity dates for the revolving credit facility and term loans without the consent of existing lenders, by obtaining additional commitments from the existing lenders and other financial institutions.

As of September 30, 2018, SL Green and the Operating Partnership had $11.8 million of outstanding letters of credit, $145.0 million drawn under the revolving credit facility and $1.5 billion outstanding under the term loan facilities, with total undrawn capacity of $1.3 billion under the 2017 credit facility. At September 30, 2018 and December 31, 2017, the revolving credit facility had a carrying value of $136.7 million and $30.3 million, respectively, net of deferred financing costs. At September 30, 2018 and December 31, 2017, the term loan facilities had a carrying value of $1.5 billion and $1.5 billion, respectively, net of deferred financing costs.

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

We also provide a guaranty of the Operating Partnership's obligations under its $350.0 million Senior Notes due 2021, which were issued in August 2018. The notes bear interest at a floating rate, reset quarterly, equal to three-month LIBOR plus 98 basis points. The notes will mature in August 2021 and can be redeemed at par beginning in August 2019.

Restrictive Covenants

The terms of the 2017 credit facility and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, 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, 2018 and December 31, 2017, we were in compliance with all such covenants.

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 the profit participation, which is included in other income on the consolidated statements of operations, was $0.9 million and $2.6 million for the three and nine months ended September 30, 2018, respectively, and was $0.8 million and $2.5 million for the three and nine months ended September 30, 2017, respectively.

We also recorded expenses, inclusive of capitalized expenses, of $2.4 million and $7.0 million for the three and nine months ended September 30, 2018, respectively, for these services (excluding services provided directly to tenants), and $2.6 million and $7.1 million for the three and nine months ended September 30, 2017, 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 $2.6 million and $8.2 million for the three and nine months ended September 30, 2018, respectively. The amount was $3.0 million and $9.2 million for the three and nine months ended September 30, 2017, respectively.

Insurance

We obtain insurance coverage through an insurance program administered by SL Green. In connection with this program, we incurred insurance expense of approximately $1.0 million and $3.2 million for the three and nine months ended September 30, 2018, respectively. We incurred insurance expense of approximately $1.3 million and $4.1 million for the three and nine months ended September 30, 2017, respectively.

Related Party Payable to SL Green

On August 22, 2016, we issued a promissory note to our parent company in the amount of $23.8 million which bears interest at an annual rate of 6.0%, compounded quarterly. This note matured on August 22, 2018.

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 Subsidiary Series A Preferred Units, with a liquidation preference of $1,000.00 per unit. In August 2015, the Company issued 109,161 Subsidiary Series A Preferred Units in conjunction with an acquisition. The Subsidiary 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 Subsidiary 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 Subsidiary Series B Preferred Units. The Subsidiary Series B Preferred Units can be converted at any time, at the option of the unitholder, into a number of common stock equal to 6.71348 shares of SL Green common stock for each Subsidiary Series B Preferred Unit. As of September 30, 2018, no Subsidiary 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 September 30, 2018, the carrying amount 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 us either by direct ownership or by indirect ownership through our general partner, which is its wholly-owned subsidiary.

Intercompany transactions between SL Green and us 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.

In January 2018, the partnership agreement for our investment in 919 Third Avenue was modified resulting in the Company no longer having a controlling interest in this investment. As a result the investment was deconsolidated as of January 1, 2018. The Company recorded its non-controlling interest at fair value resulting in a $54.9 million fair value adjustment in the consolidated statement of operations. This fair value was determined using a third party valuation which primarily utilized cash flow projections that apply, among other things, estimated revenue and expense growth rates, discount rates and capitalization rates, as well as sales comparison approach, which utilizes comparable sales, listings and sales contracts. All of which are classified as Level 3 inputs.

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.

(2) At September 30, 2018, debt and preferred equity investments had an estimated fair value ranging between $2.0 billion and $2.2 billion. At December 31, 2017, debt and preferred equity investments had an estimated fair value ranging between $2.1 billion and $2.3 billion.

Disclosure about fair value of financial instruments was based on pertinent information available to us as of September 30, 2018 and December 31, 2017. 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 sheet at fair value. Derivatives that are not hedges are adjusted to fair value through earnings. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedge asset, liability, or firm commitment through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. Reported net income and equity may increase or decrease prospectively, depending on future levels of interest rates and other variables affecting the fair values of derivative instruments and hedged items, but will have no effect on cash flows. Currently, all of our designated derivative instruments are effective hedging instruments. As of September 30, 2018, 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 income, and are recognized into earnings over the term of the related senior unsecured notes. As of September 30, 2018 and December 31, 2017, the deferred net losses from these terminated hedges, which are included in accumulated other comprehensive income relating to net unrealized loss on derivative instruments, was approximately zero and $1.3 million, respectively.

14. Commitments and Contingencies

Legal Proceedings

As of September 30, 2018, 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

During the nine months ended September 30, 2018, Ticonderoga Insurance Company, or Ticonderoga, a Vermont licensed captive insurance company and an affiliate of SL Green, became a member of the Federal Home Loan Bank of New York, or FHLBNY. As a member, Ticonderoga may borrow funds from the FHLBNY in the form of secured advances. As of September 30, 2018, certain debt and preferred equity investments of the Company were pledged as collateral to secure advances under the FHLBNY facility. If Ticonderoga or SL Green are unable to repay the advances upon the termination of Ticonderoga's membership, the maximum potential amount of future payments the Company could be required to make under the secured advances is $13.0 million.

Environmental Matters

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

15. Segment Information

The Company has two reportable segments, real estate and debt and preferred equity investments. We evaluate real estate performance and allocate resources based on earnings contribution to income from continuing operations.

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

Selected consolidated results of operations for the three and nine months ended September 30, 2018 and 2017, and selected asset information as of September 30, 2018 and December 31, 2017, regarding our operating segments are as follows (in thousands):

Interest costs for the debt and preferred equity segment includes actual costs incurred for investments collateralizing the MRAs. Interest is imputed on the remaining investments 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 excluding marketing, general and administrative expenses. All other expenses, except interest, relate entirely to the real estate assets. For the three and nine months ended September 30, 2018 marketing, general and administrative expenses totaled $0.1 million and $0.4 million, respectively. For the three and nine months ended September 30, 2017 marketing, general and administrative expenses totaled $0.1 million and $0.3 million, respectively.

There were no transactions between the above two segments.

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.

We are engaged in the acquisition, ownership, management and operation of commercial and residential real estate properties, principally office properties, and also own land for future development in the New York metropolitan area.

As of September 30, 2018, we owned the following interests in properties in the New York metropolitan area, primarily in midtown Manhattan. Our investments located outside of Manhattan are referred to as the Suburban properties:

Location	Type	Number of Properties	Approximate Square Feet (unaudited)	Weighted Average Occupancy(1) (unaudited)
Commercial:
Manhattan	Office(2)(3)	15	8,303,245	93.6	%
	Retail(4)(5)	5	364,816	98.9	%
	Development/Redevelopment	1	160,000	—	%
		21	8,828,061	92.2	%
Suburban	Office	6	1,432,400	93.8	%

Total commercial properties		28	10,312,461	92.4	%
Residential:
Manhattan	Residential(4)	—	222,855	95.8	%
Total portfolio		28	10,535,316	92.5	%

(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) Includes one unconsolidated joint venture property at 919 Third Avenue comprised of approximately 1,454,000 square feet.

(3) Includes 1 unconsolidated tenancy-in-common (or "TIC") interest at 2 Herald Square, which is under contract for sale as of September 30, 2018.

(4) As of September 30, 2018, we owned a building at 315 West 33rd Street, also known as The Olivia, that was comprised of approximately 270,132 square feet (unaudited) of retail space and approximately 222,855 square feet (unaudited) of residential space. For the purpose of this report, we have included this building in the number of retail properties we own. However, we have included only the retail square footage in the retail approximate square footage, and have listed the balance of the square footage as residential square footage.

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

As of September 30, 2018, we held debt and preferred equity investments with a book value of $2.0 billion.

Critical Accounting Policies

Refer to the 2017 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 three and nine months ended September 30, 2018.

Rental, Escalation and Reimbursement Revenues

Rental revenue decreased primarily as a result of the effect of the deconsolidation of 919 Third Avenue ($23.9 million) and Disposed Properties ($8.8 million).

Escalation and reimbursement revenue decreased primarily as a result of the effect of the deconsolidation of 919 Third Avenue ($5.4 million), partially offset by increased recoveries at our Same-Store properties ($1.4 million).

28

Investment Income

For the three months ended September 30, 2018, investment income increased primarily as a result of an increase in the weighted book balance. For the three months ended September 30, 2018, the weighted average debt and preferred equity investment balance outstanding and weighted average yield were $2.1 billion and 8.7%, respectively, compared to $2.0 billion and 9.4%, excluding our investment in Two Herald Square which was put on non-accrual in August 2017, respectively, for the same period in 2017. As of September 30, 2018, the debt and preferred equity investments had a weighted average term to maturity of 1.8 years excluding extension options.

Other Income

Other income decreased primarily due to the deconsolidation of 919 Third Avenue and the Disposed Properties ($0.7 million).

Property Operating Expenses

Property operating expenses decreased primarily due to the deconsolidation of 919 Third Avenue and the Disposed Properties ($17.1 million).

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

Interest expense and amortization of deferred financing costs, net of interest income, decreased primarily as a result of the deconsolidation of 919 Third Avenue ($6.6 million) in the first quarter of 2018, and the amendment of the 2012 credit facility ($11.5 million). The weighted average consolidated debt balance outstanding was $1.4 billion for the three months ended September 30, 2018 compared to $3.4 billion for the three months ended September 30, 2017. The consolidated weighted average interest rate was 5.14% for three months ended September 30, 2018 as compared to 3.82% for the three months ended September 30, 2017.

Depreciation and Amortization

Depreciation and amortization decreased primarily as a result of the deconsolidation of deconsolidation of 919 Third Avenue and the Disposed Properties ($12.1 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 and redemption of certain debt and preferred equity positions accounted for under the equity method ($2.9 million).

(Loss) Gain on Sale of Real Estate

During the three months ended September 30, 2018 we recognized a loss on sale related to our interest in Reckson Executive Park ($2.6 million).

Comparison of the nine months ended September 30, 2018 to the nine months ended September 30, 2017

The following comparison for the nine months ended September 30, 2018, or 2018, to the nine months ended September 30, 2017, or 2017, makes reference to the effect of the following:

i. “Same-Store Properties,” which represents all operating properties owned by us at January 1, 2017 and still owned by us in the same manner at September 30, 2018 (Same-Store Properties totaled24 of our 25 consolidated properties),

Rental, Escalation and Reimbursement Revenues

Rental revenue decreased primarily as a result of the deconsolidation of 919 Third Avenue ($71.5 million) and the Disposed Properties ($24.7 million).

Escalation and reimbursement revenue decreased primarily as a result of thedeconsolidation of 919 Third Avenue ($15.5 million), partially offset by higher recoveries at our Same-Store Properties ($5.3 million).

30

Investment Income

For the nine months ended September 30, 2018, investment income decreased primarily as a result of previously unrecognized income in the second quarter of 2017 net with 2018 income related to our preferred equity investment in 885 Third Avenue ($7.2 million), partially offset by a larger weighted average book balance and an increase in the LIBOR benchmark rate. For the nine months ended September 30, 2018, the weighted average debt and preferred equity investment balance outstanding and weighted average yield were $2.1 billion and 9.0%, respectively, compared to $1.9 billion and 9.3%, excluding our investment in Two Herald Square which was put on non-accrual in August 2017, respectively, for the same period in 2017. As of September 30, 2018, the debt and preferred equity investments had a weighted average term to maturity of 1.8 years excluding extension options.

Other Income

Other incomeincreased primarily as a result of real estate tax refunds at our Same-Store Properties ($4.1 million) and lease termination income earned at 1185 Avenue of the Americas ($2.9 million).

Property Operating Expenses

Property operating expenses decreased primarily due to the deconsolidation of 919 Third Avenue and the Disposed Properties ($48.8 million), which was partially offset by increased real estate taxes at our Same-Store Properties ($5.2 million).

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

Interest expense and amortization of financing costs, net of interest income, decreased primarily as a result of the deconsolidation of 919 Third Avenue ($19.9 million) in the first quarter of 2018 and the amendment of the 2012 credit facility ($29.6 million). The weighted average consolidated debt balance outstanding was $1.4 billion for the nine months ended September 30, 2018 compared to $3.1 billion for the nine months ended September 30, 2017. The weighted average consolidated interest rate was 5.11% for the nine months ended September 30, 2018, as compared to 3.86% for the nine months ended September 30, 2017.

Depreciation and Amortization

Depreciation and amortization decreased primarily as a result of the deconsolidation of 919 Third Avenue ($25.0 million) and Disposed Properties ($10.4 million), which included the sale of 16 Court Street ($2.8 million) in the fourth quarter of 2017, and the sale of 680/750 Washington Boulevard ($1.6 million) in the third 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 repayment and/or redemption of certain debt and preferred equity positions accounted for under the equity method ($6.7 million).

Purchase price and other fair value adjustments

In January 2018, the partnership agreement for our investment in 919 Third Avenue was modified resulting in our partner now having substantive participating rights in the venture and the Company no longer having a controlling interest in the investment. As a result the investment in this property was deconsolidated as of January 1, 2018. The Company recorded its non-controlling interest at fair value resulting in a $54.9 million fair value adjustment in the consolidated statement of operations. This fair value was allocated to the assets and liabilities, including identified intangibles of the property.

(Loss) gain on sale of real estate

During the nine months ended September 30, 2018, we recognized a loss on the sale of 635 Madison Avenue ($14.1 million), a loss on the sale of Reckson Execute Park ($2.6 million), and a loss on the sale of 115-117 Stevens Avenue ($0.7 million). 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).

Depreciable real estate reserves

During the nine months ended September 30, 2017, we recorded an $85.7 million charge in connection with 520 White Plains Road in Tarrytown, NY, 125 Chubb Way in Lyndhurst, NJ and 680/750 Washington Boulevard in Stamford, Connecticut.

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, 2017 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

31

repayments of outstanding indebtedness (which may include exchangeable debt) and for debt and preferred equity investments may include:

(1) Cash flow from operations;

(2) Cash on hand;

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

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

(5) 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, cash equivalents, and restricted cash were $75.2 million and $115.8 million at September 30, 2018 and 2017, respectively, representing a decrease of $40.6 million. The decrease was due to the following changes in cash flows (in thousands):

	Nine Months Ended September 30,
	2018			2017			Increase (Decrease)
Net cash provided by operating activities	$	292,572		$	285,616		$	6,956
Net cash (used in) provided by investing activities	$	128,468		$	(92,518	)	$	220,986
Net cash (used in) financing activities	$	(422,992	)	$	(180,752	)	$	(242,240	)

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, 2018, our operating portfolio was 92.5% 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. During the nine months ended September 30, 2018, when compared to the nine months ended September 30, 2017, the change in investing cash flows was due to the following activities (in thousands):

2017 Credit Facility

In November 2017, the Company, SL Green and the Operating Partnership entered into an amendment to the credit facility, referred to as the 2017 credit facility, that was originally entered into in November 2012. The amendment resulted in the Company no longer being a borrower, and instead is providing a guarantee of the facility. The 2012 credit facility had a carrying value of $1.2 billion, net of deferred financing costs, as of the amendment date and was removed from our consolidated balance sheet and shown as a non-cash capital contribution. SL Green and the Operating Partnership remain borrowers jointly and severally obligated under the 2017 credit facility. As of September 30, 2018, the 2017 credit facility consisted of a $1.5 billion revolving credit facility, a $1.3 billion term loan (or "Term Loan A"), and a $200.0 million term loan (or "Term Loan B") with maturity dates of March 31, 2022, March 31, 2023, and November 21, 2024, respectively. The revolving credit facility has twosix-month as-of-right extension options to March 31, 2023. SL Green and the Operating Partnership also have an option, subject to customary conditions, to increase the borrowing capacity of the credit facility to $4.5 billion at any time prior to the maturity dates for the revolving credit facility and term loans without the consent of existing lenders, by obtaining additional commitments from the existing lenders and other financial institutions.

As of September 30, 2018, SL Green and the Operating Partnership had $11.8 million of outstanding letters of credit, $145.0 million drawn under the revolving credit facility and $1.5 billion outstanding under the term loan facilities, with total undrawn capacity of $1.3 billion under the 2017 credit facility. At September 30, 2018 and December 31, 2017, the revolving credit facility had a carrying value of $136.7 million and $30.3 million, respectively, net of deferred financing costs. At September 30, 2018 and December 31, 2017, the term loan facilities had a carrying value of $1.5 billion and $1.5 billion, respectively, net of deferred financing costs.

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

Restrictive Covenants

The terms of the 2017 credit facility and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, 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, 2018 and December 31, 2017, 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

33

investments. A hypothetical 100 basis point increase in interest rates along the entire interest rate curve for 2018 would decrease our annual interest cost, net of interest income from variable rate debt and preferred equity investments, by approximately $10.7 million. At September 30, 2018, 72.4% 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 $0.9 billion bears interest at fixed rates, and therefore the fair value of these instruments is affected by changes in the market interest rates. Our variable rate debt as of September 30, 2018 bore interest based on a spread of LIBOR plus 234 basis points to LIBOR plus 340 basis points.

Contractual Obligations

Refer to our 2017 Annual Report on Form 10-K for a discussion of our contractual obligations. There have been no material changes, outside the ordinary course of business, to these contractual obligations during the three and nine months ended September 30, 2018.

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, 2018, we expect to incur $38.1 million of recurring capital expenditures and $18.7 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

We are 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. Separate property and liability coverage may be purchased on a stand-alone basis for certain assets. Additionally, SL Green's captive insurance company, Belmont Insurance Company, or Belmont, provides coverage for certain policies including NBCR terrorist acts above a deductible. Since March 31, 2018, SL Green's second captive insurance company, Ticonderoga Insurance Company, or Ticonderoga, reinsures the NBCR risk that was retained by Belmont. If Ticonderoga is required to pay a claim under SL Green's insurance policies, SL Green would ultimately record the loss to the extent of Ticonderoga's payment. However, there is no assurance that in the future we will be able to procure coverage at a reasonable cost. Further, if we experience losses that are uninsured or that exceed policy limits, we could lose the capital invested in the damaged properties as well as the anticipated future cash flows from those properties. Additionally, our debt instruments contain customary covenants requiring us to maintain insurance and we could default under debt our instruments if the cost and/or availability of certain types of insurance make it impractical or impossible to comply with such covenants relating to insurance. Belmont provides coverage solely on properties owned by SL Green or its affiliates.

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

In connection with SL Green's program, we incurred insurance expense of approximately $1.0 million and $3.2 million for the three and nine months ended September 30, 2018, respectively. We incurred insurance expense of approximately $1.3 million and $4.1 million for the three and nine months ended September 30, 2017, respectively.

34

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.

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, 2018 and Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in our Annual Report on Form 10-K for the year ended December 31, 2017. Our exposures to market risk have not changed materially since December 31, 2017.

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 the Company 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 the Company that would potentially be subject to disclosure under the Exchange Act and the rules and regulations promulgated thereunder.

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 94.90% owned by SL Green Realty Corp., or SL Green, as of September 30, 2018. 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.

We are engaged in the acquisition, ownership, management and operation of commercial and residential real estate properties, principally office properties, and also own land for future development in the New York metropolitan area.

As of September 30, 2018, we owned the following interests in properties in the New York metropolitan area, primarily in midtown Manhattan. Our investments located outside of Manhattan are referred to as the Suburban properties:

Location	Type	Number of Properties	Approximate Square Feet (unaudited)	Weighted Average Occupancy(1) (unaudited)
Commercial:
Manhattan	Office(2)(3)	15	8,303,245	93.6	%
	Retail(4)(5)	5	364,816	98.9	%
	Development/Redevelopment	1	160,000	—	%
		21	8,828,061	92.2	%
Suburban	Office	6	1,432,400	93.8	%
	Retail	1	52,000	100.0	%
		7	1,484,400	94.0	%
Total commercial properties		28	10,312,461	92.4	%
Residential:
Manhattan	Residential(4)	—	222,855	95.8	%
Total portfolio		28	10,535,316	92.5	%

(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) Includes one unconsolidated joint venture property at 919 Third Avenue comprised of approximately 1,454,000 square feet.

(3) Includes one unconsolidated tenancy-in-common (or "TIC") interest at 2 Herald Square, which is under contract for sale as of September 30, 2018.

(4) As of September 30, 2018, we owned a building at 315 West 33rd Street, also known as The Olivia, that was comprised of approximately 270,132 square feet (unaudited) of retail space and approximately 222,855 square feet (unaudited) of residential space. For the purpose of this report, we have included this building in the number of retail properties we own. However, we have included only the retail square footage in the retail approximate square footage, and have listed the balance of the square footage as residential square footage.

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

As of September 30, 2018, we held debt and preferred equity investments with a book value of $2.0 billion.

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, 2018 and the results of operations for the periods presented have been included. The operating results for the period presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. These financial statements should be read in conjunction with the financial statements and accompanying notes included in the Annual Report on Form 10-K for the year ended December 31, 2017.

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

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

Investment in Commercial Real Estate Properties

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

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted) to be generated by the property is less than the carrying value of the property. To the extent impairment has occurred, the loss will be measured as the excess of the carrying amount of the property over the calculated fair value of the property. We also evaluate our real estate properties for impairment when a property has been classified as held for sale. Real estate assets held for sale are valued at the lower of their carrying value or fair value less costs to sell.

We recognized $1.3 million and $5.5 million of rental revenue for the three and nine months ended September 30, 2018, respectively, and $4.3 million and $12.7 million for the three and nine months ended September 30, 2017, respectively, for the amortization of aggregate below-market leases in excess of above-market leases and a reduction in lease origination costs, resulting from the allocation of the purchase price of the applicable properties.

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, 2018 and December 31, 2017 (in thousands):

	September 30, 2018			December 31, 2017
Identified intangible assets (included in other assets):
Gross amount	$	213,421		$	276,163
Accumulated amortization	(199,668		)	(236,737		)
Net(1)	$	13,753		$	39,426
Identified intangible liabilities (included in deferred revenue):
Gross amount	$	230,275		$	496,438
Accumulated amortization	(214,804		)	(366,091		)
Net(1)	$	15,471		$	130,347

(1) As of September 30, 2018 and December 31, 2017, $0.0 million and $0.1 million, respectively and $0.0 million and $0.1 million, 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, 2018.

Reserve for Possible Credit Losses

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

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during the three and nine months ended September 30, 2018 and 2017.

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

Income Taxes

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 within general partner capital in our consolidated financial statements.

Use of Estimates

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

Concentrations of Credit Risk

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

We perform ongoing credit evaluations of our tenants and require most tenants to provide security deposits or letters of credit. Though these security deposits and letters of credit are insufficient to meet the total value of a tenant's lease obligation, they are a measure of good faith and a source of funds to offset the economic costs associated with lost revenue and the costs associated with re-tenanting a space. The properties in our real estate portfolio are located in the New York metropolitan area. The tenants located in our buildings operate in various industries. 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, 2018. For the three months ended September 30, 2018, 14.7%, 11.0%, 8.7%, 8.4%, 8.2%, 7.6%, 7.4%, 7.1% and 5.8% of our annualized cash 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, 1350 Avenue of the Americas, and 711 Third Avenue, respectively. 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 2018, The Securities and Exchange Commission adopted a final rule that eliminated or amended disclosure requirements that were redundant or outdated in light of changes in its requirements, generally accepted accounting principles, or changes in the business environment. The commission also referred certain disclosure requirements to the Financial Accounting Standards Board for potential incorporation into generally accepted accounting principles. The Company assessed the impact of this rule and determined that the changes resulted in clarification or expansion of existing requirements. The Company adopted the rule on November 5, 2018 and it did not have a material impact on the Company’s consolidated financial statements.

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

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

In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments- Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. These amendments provide additional guidance related to equity securities without a readily determinable fair value, forward contracts and options purchased on those equity securities and fair value option liabilities. The Company adopted the guidance on July 1, 2018, and it did not have a material impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities, and in July 2018, the FASB issued ASU No. 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. The amendments in the new standards will permit more flexibility in hedging interest rate risk for both variable rate and fixed rate financial instruments. The standards will also enhance the presentation of hedge results in the financial statements. The guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. The Company has not yet adopted the guidance, and does not expect a material impact on the Company’s consolidated financial statements when the new standards are implemented.

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

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

In February 2016, the FASB issued ASU No. 2016-02, Leases, and in July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases and ASU No. 2018-11, Leases (Topic 842): Targeted Improvements. This guidance requires lessees to recognize lease assets and lease liabilities for those leases classified as operating leases under the previous standard. Depending on the lease classification, lessees will recognize expense based on the effective interest method for finance leases or on a straight-line basis for operating leases. The accounting applied by a lessor, inclusive of the effect of a practical expedient offered in ASU No. 2018-11 that allows lessors to not separate non-lease components from the related lease components under certain conditions, which the Company expects most of its leases to qualify for and to adopt, is largely unchanged from that applied under the previous standard. However, the Company will apply this guidance to the ground leases under which the Company is lessee. The Company is required to record a liability for the obligation to make payments under the lease and an asset for the right to use the underlying asset during the lease term and will also apply the new expense recognition requirements given the lease classification. While the Company is continuing to assess all potential impacts of the standard, we expect total liabilities and total assets to increase by $0.1 to $0.2 billion as of the date of adoption. This guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The Company expects to adopt this guidance January 1, 2019 and will apply the modified retrospective approach, and anticipates electing the package of practical expedients that allows an entity to not reassess (i) whether any expired or existing contracts are or contain leases, (ii) lease classification for any expired or existing leases and (iii) initial direct costs for any expired or existing leases.

In January 2016, the FASB issued ASU 2016-01 (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value through earnings, to record changes in instrument-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income, use the exit price notion when measuring an instrument’s fair value for disclosure and to separately present financial assets and liabilities by measurement category and form of instrument on the balance sheet or in the notes to the financial statements. The Company adopted the guidance effective January 1, 2018, and it had no impact on the Company’s consolidated financial statements.

In May 2014, the FASB issued a new comprehensive revenue recognition guidance which requires us to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods and services (ASU 2014-09). The FASB also issued implementation guidance in March 2016, April 2016 and May 2016 - ASU’s 2016-08, 2016-10 and 2016-12, respectively. The Company adopted this guidance on January 1, 2018. Since the Company’s revenue is related to leasing activities, the adoption of this guidance did not have a material impact on the consolidated financial statements. The new guidance is applicable to service contracts with joint ventures for which the Company earns property management fees, leasing commissions and development and construction fees. The adoption of this new guidance did not change the accounting for these fees as the pattern of recognition of revenue does not change with the new guidance. We will continue to recognize revenue over time on these contracts because the customer simultaneously receives and consumes the benefits provided by our performance.

In February 2017, the FASB issued ASU No. 2017-05 to clarify the scope of asset derecognition guidance in Subtopic 610-20, which also provided guidance on accounting for partial sales of nonfinancial assets.  Subtopic 610-20 was issued in May 2014 as part of ASU 2014-09.  The Company adopted this guidance on January 1, 2018, and applied the modified retrospective approach. The Company elected to adopt the practical expedient under ASC 606, Revenue from Contracts with Customers, which allows an entity to apply the guidance only to contracts with non-customers that are open based on ASU 360-20, Real Estate Sales, (i.e. failed sales) as of the adoption date. The adoption had no impact on the consolidated financial statements as the Company had no open contracts based on ASC 360-20 as of December 31, 2017.

Investments in Unconsolidated Joint Ventures

Equity Method Investments and Joint Ventures [Abstract]

Investments in Unconsolidated Joint Ventures

Investments in Unconsolidated Joint Ventures

We have investments in several real estate joint ventures with various partners. As of September 30, 2018 and December 31, 2017, none of our investments in unconsolidated joint ventures were VIEs. All of the investments below are voting interest entities. As we do not control the joint ventures listed below, we account for them under the equity method of accounting.

The table below provides general information on each of our joint ventures as of September 30, 2018:

Property	Partner	Ownership Interest(1)	Economic Interest(1)	Unaudited Approximate Square Feet	Acquisition Date(2)	Acquisition Price(2) (in thousands)
919 Third Avenue(3)	New York State Teacher's Retirement System	51.00%	51.00%	1,454,000	January 2007	$	1,256,727
131-137 Spring Street	Invesco Real Estate	20.00%	20.00%	68,342	August 2015	277,750
2 Herald Square(4)	(4)	49.00%	49.00%	369,000	May 2018	266,000

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

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

(3) In January 2018, the partnership agreement for our investment was modified resulting in the Company no longer having a controlling interest in this investment. As a result the investment was deconsolidated as of January 1, 2018. The Company recorded its non-controlling interest at fair value resulting in a $54.9 million fair value adjustment in the consolidated statement of operations. This fair value was allocated to the assets and liabilities, including identified intangibles of the property.

(4) In May 2018, SL Green assigned the Company a 49.0% tenancy-in-common interest in the leasehold interest in 2 Herald Square and entered into an agreement to sell this investment. Consolidation of this investment is not required as such interest does not qualify as a VIE and does not meet the control requirement for consolidation. Accordingly, we account for this investment using the equity method of accounting. We use the equity method of accounting because the shared decision-making involved in a tenancy-in-common interest investment provides us with significant influence on the operating and financial decisions of this investment.

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, 2018 and December 31, 2017, the carrying value for acquisition, development and construction arrangements were as follows (in thousands):

Loan Type	September 30, 2018		December 31, 2017		Maturity Date
Mezzanine Loan(1)	$	—	$	26,716
Mezzanine Loan and Preferred Equity(2)	—		100,000
	$	—	$	126,716

(1) The Company was redeemed on this investment in July 2018.

(2) The mezzanine loan was repaid and the preferred equity interest was redeemed in March 2018.

Disposition of Joint Venture Interests or Properties

The following table summarizes the investments in unconsolidated joint ventures disposed of during the nine months ended September 30, 2018:

Property	Ownership Interest	Disposition Date	Type of Sale	Gross Asset Valuation (in thousands)(1)		Gain (Loss) on Sale (in thousands)(2)
Mezzanine Loan(3)	33.33%	August 2018	Repayment	$	15,000	N/A

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

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

(3) Our investment in a joint venture that owned a mezzanine loan secured by a commercial property in midtown Manhattan was repaid after the joint venture received repayment of the underlying loan.

Joint Venture Mortgages and Other Loans Payable

We generally finance our joint ventures with non-recourse debt. In certain cases we have provided guarantees or master leases for tenant space, which terminate upon the satisfaction of specified circumstances or repayment of the underlying loans. The first mortgage notes and other loans payable collateralized by the respective joint venture properties and assignment of leases at September 30, 2018 and December 31, 2017, respectively, are as follows (amounts in thousands):

Property	Economic Interest (1)		Maturity Date	Interest Rate (2)			September 30, 2018			December 31, 2017

Deferred financing costs, net							(2,031		)	(2,862		)
Total joint venture mortgages and other loans payable, net							$	638,969		$	138,138

(1) Economic interest represents the Company's interests in the joint venture as of September 30, 2018. Changes in ownership or economic interests, if any, within the current year are disclosed in the notes to the investment in unconsolidated joint ventures table above.

(2) Interest rates as of September 30, 2018. Floating rate debt is presented with the stated interest rate spread over 30-day LIBOR, unless otherwise specified.

The combined balance sheets for the unconsolidated joint ventures at September 30, 2018 and December 31, 2017 are as follows (in thousands):

(1) Interest rate as of September 30, 2018. Floating rate debt is presented with the stated interest rate spread over 30-day LIBOR, unless otherwise specified.

(2) Our investment in the property was deconsolidated as of January 1, 2018. See Note 6, "Investments in Unconsolidated Joint Ventures".

At September 30, 2018 and December 31, 2017, 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 $1.0 billion and $1.9 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 and our ability to satisfy margin calls with cash or cash equivalents.

In June 2017, we entered into the 2017 MRA, with a maximum facility capacity of $300.0 million. In April 2018, we increased the maximum facility capacity to $400.0 million. The facility bears interest on a floating rate basis at a spread to 30-day LIBOR based on the pledged collateral and advance rate and has an initial one year term, with twoone year extension options. In June 2018, we exercised a one year extension option. At September 30, 2018, the facility had an outstanding balance of $299.4 million, net of deferred financing costs.

In July 2016, we entered into the 2016 MRA, with a maximum facility capacity of $300.0 million. In June 2018, we terminated the 2016 MRA. The facility bore interest ranging from 225 and 400 basis points over 30-day LIBOR depending on the pledged collateral and had an initial two-year term, with a one year extension option. Since December 6, 2015, we had 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 was less than $150.0 million.

2017 Credit Facility

In November 2017, the Company, SL Green and the Operating Partnership entered into an amendment to the credit facility, referred to as the 2017 credit facility, that was originally entered into in November 2012, or the 2012 credit facility. The amendment resulted in the Company no longer being a borrower and instead is providing a guarantee of the facility. The 2012 credit facility had a carrying value of $1.2 billion, net of deferred financing costs, as of the amendment date and was removed from our consolidated balance sheet and shown as a non-cash capital contribution. SL Green and the Operating Partnership remain borrowers, jointly and severally obligated, under the 2017 credit facility. As of September 30, 2018, the 2017 credit facility consisted of a $1.5 billion revolving credit facility, a $1.3 billion term loan (or "Term Loan A"), and a $200.0 million term loan (or "Term Loan B") with maturity dates of March 31, 2022, March 31, 2023, and November 21, 2024, respectively. The revolving credit facility has twosix-month as-of-right extension options to March 31, 2023. SL Green and the Operating Partnership also have an option, subject to customary conditions, to increase the capacity of the credit facility to $4.5 billion at any time prior to the maturity dates for the revolving credit facility and term loans without the consent of existing lenders, by obtaining additional commitments from the existing lenders and other financial institutions.

As of September 30, 2018, SL Green and the Operating Partnership had $11.8 million of outstanding letters of credit, $145.0 million drawn under the revolving credit facility and $1.5 billion outstanding under the term loan facilities, with total undrawn capacity of $1.3 billion under the 2017 credit facility. At September 30, 2018 and December 31, 2017, the revolving credit facility had a carrying value of $136.7 million and $30.3 million, respectively, net of deferred financing costs. At September 30, 2018 and December 31, 2017, the term loan facilities had a carrying value of $1.5 billion and $1.5 billion, respectively, net of deferred financing costs.

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

Preferred Units

Through a consolidated subsidiary, we have authorized up to 109,1613.50% Series A Preferred Units of limited partnership interest, or the Subsidiary Series A Preferred Units, with a liquidation preference of $1,000.00 per unit. In August 2015, the Company issued 109,161 Subsidiary Series A Preferred Units in conjunction with an acquisition. The Subsidiary 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 Subsidiary 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 Subsidiary Series B Preferred Units. The Subsidiary Series B Preferred Units can be converted at any time, at the option of the unitholder, into a number of common stock equal to 6.71348 shares of SL Green common stock for each Subsidiary Series B Preferred Unit. As of September 30, 2018, no Subsidiary 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 September 30, 2018, the carrying amount of the derivative remained at zero.

Fair Value Measurements

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.

In January 2018, the partnership agreement for our investment in 919 Third Avenue was modified resulting in the Company no longer having a controlling interest in this investment. As a result the investment was deconsolidated as of January 1, 2018. The Company recorded its non-controlling interest at fair value resulting in a $54.9 million fair value adjustment in the consolidated statement of operations. This fair value was determined using a third party valuation which primarily utilized cash flow projections that apply, among other things, estimated revenue and expense growth rates, discount rates and capitalization rates, as well as sales comparison approach, which utilizes comparable sales, listings and sales contracts. All of which are classified as Level 3 inputs.

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, 2018 and December 31, 2017 (in thousands):

	September 30, 2018				December 31, 2017
	Carrying Value (1)		Fair Value		Carrying Value (1)		Fair Value

	$	1,269,971	$	1,289,775	$	1,745,925	$	1,807,588

(1) Amounts exclude net deferred financing costs.

(2) At September 30, 2018, debt and preferred equity investments had an estimated fair value ranging between $2.0 billion and $2.2 billion. At December 31, 2017, debt and preferred equity investments had an estimated fair value ranging between $2.1 billion and $2.3 billion.

Disclosure about fair value of financial instruments was based on pertinent information available to us as of September 30, 2018 and December 31, 2017. 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 sheet at fair value. Derivatives that are not hedges are adjusted to fair value through earnings. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedge asset, liability, or firm commitment through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. Reported net income and equity may increase or decrease prospectively, depending on future levels of interest rates and other variables affecting the fair values of derivative instruments and hedged items, but will have no effect on cash flows. Currently, all of our designated derivative instruments are effective hedging instruments. As of September 30, 2018, 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 income, and are recognized into earnings over the term of the related senior unsecured notes. As of September 30, 2018 and December 31, 2017, the deferred net losses from these terminated hedges, which are included in accumulated other comprehensive income relating to net unrealized loss on derivative instruments, was approximately zero and $1.3 million, respectively.

Segment Reporting [Abstract]

Segment Information

Segment Information

The Company has two reportable segments, real estate and debt and preferred equity investments. We evaluate real estate performance and allocate resources based on earnings contribution to income from continuing operations.

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

Selected consolidated results of operations for the three and nine months ended September 30, 2018 and 2017, and selected asset information as of September 30, 2018 and December 31, 2017, regarding our operating segments are as follows (in thousands):

Interest costs for the debt and preferred equity segment includes actual costs incurred for investments collateralizing the MRAs. Interest is imputed on the remaining investments 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 excluding marketing, general and administrative expenses. All other expenses, except interest, relate entirely to the real estate assets. For the three and nine months ended September 30, 2018 marketing, general and administrative expenses totaled $0.1 million and $0.4 million, respectively. For the three and nine months ended September 30, 2017 marketing, general and administrative expenses totaled $0.1 million and $0.3 million, respectively.

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 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

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

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted) to be generated by the property is less than the carrying value of the property. To the extent impairment has occurred, the loss will be measured as the excess of the carrying amount of the property over the calculated fair value of the property. We also evaluate our real estate properties for impairment when a property has been classified as held for sale. Real estate assets held for sale are valued at the lower of their carrying value or fair value less costs to sell.

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

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during the three and nine months ended September 30, 2018 and 2017.

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

Income Taxes

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 within general partner capital in our consolidated 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 the New York metropolitan area. See Note 5, "Debt and Preferred Equity Investments."

Reclassification

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

Accounting Standards Updates

Accounting Standards Updates

In August 2018, The Securities and Exchange Commission adopted a final rule that eliminated or amended disclosure requirements that were redundant or outdated in light of changes in its requirements, generally accepted accounting principles, or changes in the business environment. The commission also referred certain disclosure requirements to the Financial Accounting Standards Board for potential incorporation into generally accepted accounting principles. The Company assessed the impact of this rule and determined that the changes resulted in clarification or expansion of existing requirements. The Company adopted the rule on November 5, 2018 and it did not have a material impact on the Company’s consolidated financial statements.

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

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

In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments- Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. These amendments provide additional guidance related to equity securities without a readily determinable fair value, forward contracts and options purchased on those equity securities and fair value option liabilities. The Company adopted the guidance on July 1, 2018, and it did not have a material impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities, and in July 2018, the FASB issued ASU No. 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. The amendments in the new standards will permit more flexibility in hedging interest rate risk for both variable rate and fixed rate financial instruments. The standards will also enhance the presentation of hedge results in the financial statements. The guidance is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. The Company has not yet adopted the guidance, and does not expect a material impact on the Company’s consolidated financial statements when the new standards are implemented.

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

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

In February 2016, the FASB issued ASU No. 2016-02, Leases, and in July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases and ASU No. 2018-11, Leases (Topic 842): Targeted Improvements. This guidance requires lessees to recognize lease assets and lease liabilities for those leases classified as operating leases under the previous standard. Depending on the lease classification, lessees will recognize expense based on the effective interest method for finance leases or on a straight-line basis for operating leases. The accounting applied by a lessor, inclusive of the effect of a practical expedient offered in ASU No. 2018-11 that allows lessors to not separate non-lease components from the related lease components under certain conditions, which the Company expects most of its leases to qualify for and to adopt, is largely unchanged from that applied under the previous standard. However, the Company will apply this guidance to the ground leases under which the Company is lessee. The Company is required to record a liability for the obligation to make payments under the lease and an asset for the right to use the underlying asset during the lease term and will also apply the new expense recognition requirements given the lease classification. While the Company is continuing to assess all potential impacts of the standard, we expect total liabilities and total assets to increase by $0.1 to $0.2 billion as of the date of adoption. This guidance is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. The Company expects to adopt this guidance January 1, 2019 and will apply the modified retrospective approach, and anticipates electing the package of practical expedients that allows an entity to not reassess (i) whether any expired or existing contracts are or contain leases, (ii) lease classification for any expired or existing leases and (iii) initial direct costs for any expired or existing leases.

In January 2016, the FASB issued ASU 2016-01 (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value through earnings, to record changes in instrument-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income, use the exit price notion when measuring an instrument’s fair value for disclosure and to separately present financial assets and liabilities by measurement category and form of instrument on the balance sheet or in the notes to the financial statements. The Company adopted the guidance effective January 1, 2018, and it had no impact on the Company’s consolidated financial statements.

In May 2014, the FASB issued a new comprehensive revenue recognition guidance which requires us to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods and services (ASU 2014-09). The FASB also issued implementation guidance in March 2016, April 2016 and May 2016 - ASU’s 2016-08, 2016-10 and 2016-12, respectively. The Company adopted this guidance on January 1, 2018. Since the Company’s revenue is related to leasing activities, the adoption of this guidance did not have a material impact on the consolidated financial statements. The new guidance is applicable to service contracts with joint ventures for which the Company earns property management fees, leasing commissions and development and construction fees. The adoption of this new guidance did not change the accounting for these fees as the pattern of recognition of revenue does not change with the new guidance. We will continue to recognize revenue over time on these contracts because the customer simultaneously receives and consumes the benefits provided by our performance.

In February 2017, the FASB issued ASU No. 2017-05 to clarify the scope of asset derecognition guidance in Subtopic 610-20, which also provided guidance on accounting for partial sales of nonfinancial assets.  Subtopic 610-20 was issued in May 2014 as part of ASU 2014-09.  The Company adopted this guidance on January 1, 2018, and applied the modified retrospective approach. The Company elected to adopt the practical expedient under ASC 606, Revenue from Contracts with Customers, which allows an entity to apply the guidance only to contracts with non-customers that are open based on ASU 360-20, Real Estate Sales, (i.e. failed sales) as of the adoption date. The adoption had no impact on the consolidated financial statements as the Company had no open contracts based on ASC 360-20 as of December 31, 2017.

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.

In January 2018, the partnership agreement for our investment in 919 Third Avenue was modified resulting in the Company no longer having a controlling interest in this investment. As a result the investment was deconsolidated as of January 1, 2018. The Company recorded its non-controlling interest at fair value resulting in a $54.9 million fair value adjustment in the consolidated statement of operations. This fair value was determined using a third party valuation which primarily utilized cash flow projections that apply, among other things, estimated revenue and expense growth rates, discount rates and capitalization rates, as well as sales comparison approach, which utilizes comparable sales, listings and sales contracts. All of which are classified as Level 3 inputs.

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.

Schedule of Equity Method Investments [Line Items]

Schedule of general information on joint ventures

The table below provides general information on each of our joint ventures as of September 30, 2018:

Property	Partner	Ownership Interest(1)	Economic Interest(1)	Unaudited Approximate Square Feet	Acquisition Date(2)	Acquisition Price(2) (in thousands)
919 Third Avenue(3)	New York State Teacher's Retirement System	51.00%	51.00%	1,454,000	January 2007	$	1,256,727
131-137 Spring Street	Invesco Real Estate	20.00%	20.00%	68,342	August 2015	277,750
2 Herald Square(4)	(4)	49.00%	49.00%	369,000	May 2018	266,000

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

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

(3) In January 2018, the partnership agreement for our investment was modified resulting in the Company no longer having a controlling interest in this investment. As a result the investment was deconsolidated as of January 1, 2018. The Company recorded its non-controlling interest at fair value resulting in a $54.9 million fair value adjustment in the consolidated statement of operations. This fair value was allocated to the assets and liabilities, including identified intangibles of the property.

(4) In May 2018, SL Green assigned the Company a 49.0% tenancy-in-common interest in the leasehold interest in 2 Herald Square and entered into an agreement to sell this investment. Consolidation of this investment is not required as such interest does not qualify as a VIE and does not meet the control requirement for consolidation. Accordingly, we account for this investment using the equity method of accounting. We use the equity method of accounting because the shared decision-making involved in a tenancy-in-common interest investment provides us with significant influence on the operating and financial decisions of this investment.

As of September 30, 2018 and December 31, 2017, the carrying value for acquisition, development and construction arrangements were as follows (in thousands):

Loan Type	September 30, 2018		December 31, 2017		Maturity Date
Mezzanine Loan(1)	$	—	$	26,716
Mezzanine Loan and Preferred Equity(2)	—		100,000

(1) The Company was redeemed on this investment in July 2018.

(2) The mezzanine loan was repaid and the preferred equity interest was redeemed in March 2018.
