	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 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.

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

	SL Green Realty Corp., or SL Green, and the Operating Partnership were formed in June 1997. SL Green has qualified, and expects to qualify in the current fiscal year as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended, or the Code, and operates as a self-administered, self-managed REIT. A REIT is a legal entity that holds real estate interests and, through payments of dividends to stockholders, is permitted to minimize the payment of Federal income taxes at the corporate level. Unless the context requires otherwise, all references to “we,” “our,” “us” and the “Company” means ROP and all entities owned or controlled by ROP.

	On January 25, 2007, SL Green completed the acquisition of all of the outstanding shares of common stock of Reckson Associates Realty Corp., or RARC, the prior general partner of ROP. This transaction is referred to herein as the Merger.

	In connection with the closing of our 2011 revolving credit facility and 2012 credit facility, in which we, along with SL Green and the Operating Partnership are borrowers, SL Green transferred five properties with total assets aggregating to $683.8 million at November 1, 2011 and transferred three additional properties with total assets aggregating to $320.2 million at December 31, 2012, to ROP. Under the Business Combinations guidance, these were determined to be transfers of businesses between the indirect parent company and its wholly owned subsidiary. As such, the assets and liabilities were transferred at their carrying value. These transfers are required to be recorded as of the beginning of the current reporting period as though the assets and liabilities had been transferred at that date. The consolidated financial statements and financial information presented for all prior periods have been retrospectively adjusted to furnish comparative information.

	On September 30, 2012, SL Green transferred $324.9 million of its preferred equity investments to ROP, one of which was subject to a secured $50.0 million loan. Under the Business Combinations guidance, these transfers were determined to be transfers of assets between the indirect parent company and its wholly-owned subsidiary. As such, the assets were transferred at their carrying value and accounted for prospectively from the date of transfer.

	As of September 30, 2013, we owned the following interests in commercial office properties in the New York Metropolitan area, primarily in midtown Manhattan, a borough of New York City. Our investments in the New York Metropolitan area also include investments in Westchester County and Connecticut, which are collectively known as the Suburban assets:



	Location		Ownership	Number of	Square Feet	Weighted
				Properties		Average
						Occupancy (1)
	Manhattan		Consolidated properties	12	6,866,400	96	%

	Suburban		Consolidated properties	17	2,785,500	78.3	%

				29	9,651,900	90.9	%

	______________________________

	-1	The weighted average occupancy represents the total leased square feet divided by total available rentable square feet.

	At September 30, 2013, we also own a development property encompassing approximately 104,000 square feet as well as an inventory of development parcels that aggregated approximately 81 acres of land in four separate parcels on which we can, based on estimates at September 30, 2013, develop approximately 1.1 million square feet of office space and in which we have invested approximately $67.8 million. As of September 30, 2013, we also held preferred equity investments and an investment in an unconsolidated joint venture that holds a preferred equity interest in a retail property located in Manhattan with an aggregate book value of $378.8 million.

	Basis of Quarterly Presentation

	The accompanying consolidated financial statements include the consolidated financial position of ROP and the Service Companies (as defined below) at September 30, 2013 and December 31, 2012, the consolidated results of their operations for the three and nine months ended September 30, 2013 and 2012, their statement of capital for the nine months ended September 30, 2013 and their statement of cash flows for the nine months ended September 30, 2013 and 2012. Our investments in majority-owned and controlled real estate joint ventures are reflected in the accompanying financial statements on a consolidated basis with a reduction for the noncontrolling partners’ interests. ROP’s investments in joint ventures, where it owns less than a controlling interest, are reflected in the accompanying consolidated financial statements using the equity method of accounting. The Service Companies, which provide management, development and construction services to ROP, include Reckson Management Group, Inc., RANY Management Group, Inc., Reckson Construction & Development LLC and Reckson Construction Group New York, Inc. (collectively, the “Service Companies”). All significant intercompany balances and transactions have been eliminated in the consolidated financial statements.

	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, 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 U.S. GAAP 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, 2013 and the results of operations for the periods presented have been included. The 2013 operating results for the periods presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. These financial statements should be read in conjunction with the financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2012.

	The balance sheet at December 31, 2012 has been derived from the audited financial statements at that date but does not include all the information and footnotes required by U.S. GAAP for complete financial statements.

	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 or as preferred equity investments. See Note 4, “Preferred Equity and Other Investment.” ROP’s investments in majority-owned and controlled real estate joint ventures are reflected in the accompanying financial statements on a consolidated basis with a reduction for the noncontrolling partners’ interests. All significant intercompany balances and transactions have been eliminated.

	We consolidate a variable interest entity, or VIE, in which we are considered the primary beneficiary. The primary beneficiary of a VIE 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.

	A noncontrolling interest in a consolidated subsidiary is defined as the portion of the equity (net assets) in a subsidiary not attributable, directly or indirectly, to a parent. Noncontrolling interests are required to be presented as a separate component of capital in the consolidated balance sheet and the presentation of net income was modified to present earnings and other comprehensive income to be attributed to controlling and noncontrolling interests.

	We assess the accounting treatment for each joint venture and preferred equity investment. This assessment includes a review of each joint venture or limited liability company agreement to determine which party has what rights and whether those rights are protective or participating. For all VIE’s, we review such agreements in order to determine which party has the power to direct the activities that most significantly impact the entity’s economic performance. In situations where we and our partner approves, among other things, the annual budget, receives a detailed monthly reporting package from us, meets on a quarterly basis to review the results of the joint venture, reviews and approves the joint venture’s tax return before filing, and approves all leases that cover more than a nominal amount of space relative to the total rentable space at each property, we do not consolidate the joint venture as we consider these to be substantive participation rights that result in shared power of the activities that most significantly impact the performance of our joint venture. Our joint venture agreements typically contain certain protective rights such as the requirement of partner approval to sell, finance or refinance the property and the payment of capital expenditures and operating expenditures outside of the approved budget or operating plan.

	Investment in Commercial Real Estate Properties

	On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be 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 and without interest charges for consolidated properties) 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. In addition, we assess our unconsolidated joint venture investments 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 investment for impairment based on the joint venture’s projected discounted cash flows. We do not believe that the values of any of our consolidated properties or equity investment were impaired at either September 30, 2013 or December 31, 2012.

	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 tenants improvements) and other intangible assets over their estimated useful lives, which generally range from three to 40 years and from one to 14 years, respectively. The values of the above- and below-market leases are amortized and recorded as either an increase (in the case of below-market leases) or a decrease (in the case of above-market leases) to rental income over the remaining term of the associated lease, which generally range from one to 14 years. The value associated with in-place leases is amortized 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 amortized such below market lease value into rental income over the renewal period.

	We recognized an increase of approximately $5.5 million, $16.2 million, $4.2 million and $14.1 million in rental revenue for the three and nine months ended September 30, 2013 and 2012, respectively, for the amortization of aggregate below-market leases in excess of above-market leases and reductions in lease origination costs, resulting from the allocation of the purchase price of the applicable properties. We recognized an increase in interest expense for the amortization of above-market rate mortgages assumed of approximately $0.1 million, $0.4 million, $0.1 million and $0.4 million for the three and nine months ended September 30, 2013 and 2012, respectively.

	The following summarizes our identified intangible assets (acquired above-market leases and in-place leases) and intangible liabilities (acquired below-market leases) as of September 30, 2013 and December 31, 2012 (in thousands):



		September 30,			December 31,
		2013			2012
	Identified intangible assets (included in other assets):

	Gross amount	$	199,845		$	199,845

	Accumulated amortization	(137,939		)	(125,009		)
	Net	$	61,906		$	74,836

	Identified intangible liabilities (included in deferred revenue):

	Gross amount	$	399,088		$	399,088

	Accumulated amortization	(254,216		)	(227,637		)
	Net	$	144,872		$	171,451


	Investments in Unconsolidated Joint Ventures

	We account for our investments in unconsolidated joint ventures under the equity method of accounting as we exercise significant influence, but do not control the entity and are not considered to be the primary beneficiary. We consolidate the joint ventures that we control or which are VIEs and where we are considered to be the primary beneficiary. In all the joint ventures, the rights of the joint venture partner are both protective as well as participating. Unless the joint venture is determined to be a VIE and we are the primary beneficiary in a VIE, these participating rights preclude us from consolidating these joint ventures. This investment is recorded initially at cost, as investment in unconsolidated joint venture, and subsequently adjusted for equity in net income (loss) and cash contributions and distributions. Any difference between the carrying amount of this investment on our balance sheet and the underlying equity in net assets is amortized as an adjustment to equity in net income (loss) of unconsolidated joint venture over the lesser of the joint venture term or 10 years. Equity income (loss) from unconsolidated joint venture is allocated based on our ownership or economic interest in the joint venture. When a capital event (as defined in each joint venture agreement) such as a refinancing occurs, if return thresholds are met, future equity income will be allocated at our increased economic interest. We recognize incentive income from unconsolidated real estate joint ventures as income to the extent it is earned and not subject to a clawback feature. Distributions we receive from unconsolidated real estate joint ventures in excess of our basis in the investment are recorded as offsets to our investment balance if we remain liable for future obligations of the joint venture or may otherwise be committed to provide future additional financial support. In July 2012, we, along with our joint venture partner, sold One Court Square for $481.1 million, which included the assumption of $315.0 million of existing debt by the purchaser, and recognized a gain of $1.0 million on the sale of this property. In January 2013, we, along with our joint venture partner, acquired a preferred equity interest in an entity that holds an interest in a retail property located in Manhattan. See Note 4, “Preferred Equity and Other Investment.”

	Revenue Recognition

	Rental revenue is recognized on a straight-line basis over the term of the lease. Rental revenue recognition commences when the tenant takes possession or controls the physical use of the leased space. In order for the tenant to take possession, the leased space must be substantially ready for its intended use. To determine whether the leased space is substantially ready for its intended use, management evaluates whether we are or the tenant is the owner of tenant improvements for accounting purposes. When management concludes that we are the owner of tenant improvements, rental revenue recognition begins when the tenant takes possession of the finished space, which is when such tenant improvements are substantially complete. In certain instances, when management concludes that we are not the owner (the tenant is the owner) of tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the space. When management concludes that we are the owner of tenant improvements for accounting purposes, we record amounts funded to construct the tenant improvements as a capital asset. For these tenant improvements, we record amounts reimbursed by tenants as a reduction of the capital asset. When management concludes that the tenant is the owner of tenant improvements for accounting purposes, we record our contribution towards those improvements as a lease incentive, which is included in deferred leasing costs on our consolidated balance sheets and amortized as a reduction to rental revenue on a straight-line basis over the term of the lease. The excess of rents recognized over amounts contractually due pursuant to the underlying leases are included in deferred rents receivable on the accompanying consolidated balance sheets. We establish, on a current basis, an allowance for future potential tenant credit losses, which may occur against this account. The balance reflected on the consolidated balance sheets is net of such allowance.

	In addition to base rent, our tenants also generally will pay their pro rata share of increases in real estate taxes and operating expenses for the building over a base year. In some leases, in lieu of paying additional rent based upon increases in building operating expenses, the tenant will pay additional rent based upon increases in the wage rate paid to porters over the porters’ wage rate in effect during a base year or increases in the consumer price index over the index value in effect during a base year. In addition, many of our leases contain fixed percentage increases over the base rent to cover escalations.

	Electricity is most often supplied by the landlord either on a sub-metered basis, or rent inclusion basis (i.e., a fixed fee is included in the rent for electricity, which may increase based upon increases in electricity rates or increases in electrical usage by the tenant). Base building services other than electricity (such as heat, air conditioning and freight elevator service during business hours, and base building cleaning) are typically provided at no additional cost, with the tenant paying additional rent only for services which exceed base building services or for services which are provided outside normal business hours.

	These escalations are based on actual expenses incurred in the prior calendar year. If the expenses in the current year are different from those in the prior year, then during the current year, the escalations will be adjusted to reflect the actual expenses for the current year.

	We record a gain on sale of real estate when title is conveyed to the buyer, subject to the buyer’s financial commitment being sufficient to provide economic substance to the sale and we have no substantial economic involvement with the buyer.

	Interest income on preferred equity investments is recognized over the life of the investment using the effective interest method and recognized on the accrual basis. Fees received in connection with loan commitments are deferred until the loan is funded and are then recognized over the term of the loan as an adjustment to yield. Anticipated exit fees, whose collection is expected, are also recognized over the term of the loan as an adjustment to yield. Fees on commitments that expire unused are recognized at expiration.

	Income recognition is generally suspended for preferred equity investments at the earlier of the date at which payments become 90 days past due or when, in the opinion of management, a full recovery of interest income and principal becomes doubtful. Interest income recognition is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. Interest is recorded as income on impaired loans only to the extent cash is received. Several of the preferred equity investments provide for accrual of interest at specified rates, which differ from current payment terms. Interest is recognized on such loans at the accrual rate subject to management’s determination that accrued interest and outstanding principal are ultimately collectible, based on the underlying collateral and operations of the borrower. If management cannot make this determination, interest income above the current pay rate is recognized only upon actual receipt.

	If we purchase a preferred equity investment at a discount, intend to hold it until maturity and expect to recover the full value of the investment, we accrete the discount into income as an adjustment to yield over the term of the investment. If we purchase a preferred equity investment at a discount with the intention of foreclosing on the collateral, we do not accrete the discount.

Income Taxes

No provision has been made for income taxes in the accompanying consolidated financial statements since such taxes, if any, are the responsibility of the individual partners.

Reserve for Possible Credit Losses

The expense for possible credit losses in connection with 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 relate to geographic trends and product diversification, the size of the portfolio and current economic conditions. Based upon these factors, we establish the provision for possible credit loss on each individual investment. When it is probable that we will be unable to collect all amounts contractually due, the investment is considered impaired.

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the net fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. The write-off of the reserve balance is called a charge-off. We continue to assess or adjust our estimates based on the circumstances of a loan and the underlying collateral. If additional information is obtained that reflects an increased recovery of our investment, we will adjust our reserves accordingly. We recorded no loan loss reserves during the three and nine months ended September 30, 2013 and 2012. During the three and nine months ended September 30, 2012, we recorded zero and $0.5 million, respectively, in recoveries in connection with the sale of one of our debt investments. This is included in loan loss reserves, net of recoveries in the accompanying consolidated statements of income.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP 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, preferred equity investments and accounts receivable. We place our cash investments in excess of insured amounts with high quality financial institutions. The collateral securing our preferred equity investments is located in the New York Metropolitan area. See Note 4, “Preferred Equity and Other 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 rent and the costs associated with re-tenanting the space. Although the properties in our real estate portfolio are primarily located in Manhattan, we also have Suburban properties located in Westchester County and Connecticut. The tenants located in our buildings operate in various industries. Other than two tenants who account for approximately 5.2% and 3.3% of our annualized cash rent, respectively, no other tenant in our portfolio accounted for more than 3.2% of our annualized cash rent at September 30, 2013. Approximately 19%, 11%, 10%, 10% and 9% of our annualized cash rent for the three months ended September 30, 2013 was attributable to 1185 Avenue of the Americas, 919 Third Avenue, 750 Third Avenue, 810 Seventh Avenue and 1350 Avenue of the Americas, respectively.

Reclassification

Certain prior year balances have been reclassified to conform to our current year presentation primarily in order to eliminate discontinued operations from income from continuing operations and to reclassify deferred origination fees from deferred income to preferred equity and other investment.

Accounting Standards Updates

In February 2013, the FASB issued guidance on the presentation and disclosure of reclassification adjustments out of accumulated other comprehensive income, or AOCI. The standard requires an entity to present information about significant items reclassified out of AOCI by component either on the face of the statement where net income is presented or as a separate disclosure in the notes to financial statements. The guidance became effective for calendar year-end public companies beginning in the first quarter of 2013 and its adoption did not have a material impact on our consolidated financial statements.

	2012 Credit Facility

	In November 2012, we entered into a $1.6 billion credit facility, or the 2012 credit facility, which refinanced, extended and upsized the previous 2011 revolving credit facility. The 2012 credit facility consists of a $1.2 billion revolving credit facility, or the revolving credit facility, and a $400.0 million term loan, or the term loan facility. The revolving credit facility matures in March 2017 and includes two six-month extension options, subject to certain conditions and the payment of an extension fee of 10 basis points for each such extension. We also have an option, subject to customary conditions, without the consent of existing lenders, to increase the capacity under the revolving credit facility to $1.5 billion at any time prior to the maturity date for the revolving credit facility, by obtaining additional commitments from our current lenders and other financial institutions. The term loan facility matures on March 30, 2018.

	The 2012 credit facility bears interest at a spread over LIBOR ranging from (i) 100 basis points to 175 basis points for loans under the revolving credit facility and (ii) 115 basis points to 200 basis points for loans under the term loan facility, in each case based on the credit rating assigned to our senior unsecured long-term indebtedness. At September 30, 2013, the applicable spread was 145 basis points for revolving credit facility and 165 basis points for the term loan facility. At September 30, 2013, the effective interest rate was 1.64% for revolving credit facility and 2.00% for the term loan facility. We are required to pay quarterly in arrears a 15 to 35 basis point fee on the unused balance of the commitments under the revolving credit facility. As of September 30, 2013, the facility fee was 30 basis points. At September 30, 2013, we had approximately $79.1 million of outstanding letters of credit, $340.0 million borrowings under the revolving credit facility and $400.0 million outstanding under the term loan facility, with undrawn capacity of $0.9 billion under the 2012 credit facility.

	We, SL Green and the Operating Partnership are all borrowers jointly and severally obligated under the 2012 credit facility. No other subsidiary of ours is an obligor under the 2012 credit facility.

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

	Restrictive Covenants

	The terms of the 2012 credit facility 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 minimum amount of tangible net worth, a 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 its common stock or other equity interests, except to enable SL Green to continue to qualify as a REIT for Federal income tax purposes.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments	'
	Fair Value Measurements

	We are required to disclose the fair value information about our financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practicable to estimate fair value. 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 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 consist 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. The Company’s 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 measure our derivatives instruments at fair value on a recurring basis. 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 sheet include cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses, preferred equity investments, and 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 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 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, 2013 and December 31, 2012 (in thousands):



		September 30, 2013				December 31, 2012

	-1	Preferred equity investments had an estimated fair value ranging between $358.1 million and $393.9 million at September 30, 2013. At December 31, 2012, the preferred equity investments had an estimated fair value ranging between $300.0 million and $400.0 million.

	Disclosure about fair value of financial instruments is based on pertinent information available to us as of September 30, 2013. 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

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 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 will be immediately recognized in earnings. Reported net income and capital 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, 2013, the Company has designated an interest swap agreement on the $30.0 million portion of the 2012 credit facility. The following table summarizes the notional and fair value of our derivative financial instrument at September 30, 2013 based on Level 2 inputs. The notional value is an indication of the extent of our involvement in these instruments at that time, but does not represent exposure to credit, interest rate or market risks (amounts in thousands):

Gains and losses on terminated hedges are included in the accumulated other comprehensive loss, and are recognized into earnings over the remaining term of the related senior unsecured notes. As of September 30, 2013 and December 31, 2012, the deferred net losses from these terminated hedges, which are included in accumulated other comprehensive loss relating to net unrealized loss on derivative instrument, was approximately $2.8 million and $3.0 million, respectively.

Over time, the realized and unrealized gains and losses held in accumulated other comprehensive loss will be reclassified into earnings as an adjustment to interest expense in the same periods in which the hedged interest payments affect earnings. We estimate that approximately $1.0 million of the current balance held in accumulated other comprehensive loss will be reclassified into interest expense within the next 12 months.

	Cleaning/ Security/ Messenger and Restoration Services

	Through Alliance Building Services, or Alliance, First Quality Maintenance, L.P., or First Quality, provides cleaning, extermination and related services, Classic Security LLC provides security services, Bright Star Couriers LLC provides messenger services, and Onyx Restoration Works provides restoration services with respect to certain properties owned by us. Alliance is partially owned by Gary Green, a son of Stephen L. Green, the chairman of SL Green’s board of directors. In addition, First Quality has the non-exclusive opportunity to provide cleaning and related services to individual tenants at our properties on a basis separately negotiated with any tenant seeking such additional services. An affiliate of ours 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. Alliance paid the affiliate approximately $0.7 million, $2.3 million, $0.7 million and $2.1 million for the three and nine months ended September 30, 2013 and 2012, respectively. We paid Alliance approximately $1.5 million, $4.0 million, $1.4 million and $3.8 million for the three and nine months ended September 30, 2013 and 2012, respectively, for these services (excluding services provided directly to tenants).

	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 $1.8 million, $5.2 million, $1.7 million and $4.8 million for the three and nine months ended September 30, 2013 and 2012, respectively.

Segment Information	'
	Segment Information

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

	Our real estate portfolio is primarily located in the geographical markets of Manhattan, Westchester County and Connecticut. 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, real estate taxes and ground rent expense (at certain applicable properties). See Note 4, “Preferred Equity and Other Investment,” for additional details on our preferred equity and other investment.

	Selected results of operations for the three and nine months ended September 30, 2013 and 2012 and selected asset information as of September 30, 2013 and December 31, 2012, regarding our operating segments are as follows (in thousands):

	Income from continuing operations represents total revenues less total expenses for the real estate segment and total investment income and equity in net income from unconsolidated joint venture less allocated interest expense and provision for loan losses for the preferred equity and other investment segment. Interest costs for the preferred equity and other investment segment are imputed assuming 100% leverage at 2012 credit facility borrowing cost. We also allocate loan loss reserves, net of recoveries to the preferred equity and other investment. We do not allocate marketing, general and administrative expenses and transaction related costs to the preferred equity and other investment segment, since we base performance on the individual segments prior to allocating marketing, general and administrative expenses. All other expenses, except interest, relate entirely to the real estate assets. There were no transactions between the above two segments.

Accounting Policies [Abstract]	'
Principles of Consolidation	'
	Principles of Consolidation

	The consolidated financial statements include our accounts and those of our subsidiaries, which are wholly-owned or controlled by us. Entities which we do not control through our voting interest and entities which are variable interest entities, but where we are not the primary beneficiary, are accounted for under the equity method or as preferred equity investments. See Note 4, “Preferred Equity and Other Investment.” ROP’s investments in majority-owned and controlled real estate joint ventures are reflected in the accompanying financial statements on a consolidated basis with a reduction for the noncontrolling partners’ interests. All significant intercompany balances and transactions have been eliminated.

	We consolidate a variable interest entity, or VIE, in which we are considered the primary beneficiary. The primary beneficiary of a VIE 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.

	A noncontrolling interest in a consolidated subsidiary is defined as the portion of the equity (net assets) in a subsidiary not attributable, directly or indirectly, to a parent. Noncontrolling interests are required to be presented as a separate component of capital in the consolidated balance sheet and the presentation of net income was modified to present earnings and other comprehensive income to be attributed to controlling and noncontrolling interests.

	We assess the accounting treatment for each joint venture and preferred equity investment. This assessment includes a review of each joint venture or limited liability company agreement to determine which party has what rights and whether those rights are protective or participating. For all VIE’s, we review such agreements in order to determine which party has the power to direct the activities that most significantly impact the entity’s economic performance. In situations where we and our partner approves, among other things, the annual budget, receives a detailed monthly reporting package from us, meets on a quarterly basis to review the results of the joint venture, reviews and approves the joint venture’s tax return before filing, and approves all leases that cover more than a nominal amount of space relative to the total rentable space at each property, we do not consolidate the joint venture as we consider these to be substantive participation rights that result in shared power of the activities that most significantly impact the performance of our joint venture. Our joint venture agreements typically contain certain protective rights such as the requirement of partner approval to sell, finance or refinance the property and the payment of capital expenditures and operating expenditures outside of the approved budget or operating plan.
Investment in Commercial Real Estate Properties	'
	Investment in Commercial Real Estate Properties

	On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be 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 and without interest charges for consolidated properties) 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. In addition, we assess our unconsolidated joint venture investments 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 investment for impairment based on the joint venture’s projected discounted cash flows. We do not believe that the values of any of our consolidated properties or equity investment were impaired at either September 30, 2013 or December 31, 2012.

	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 tenants improvements) and other intangible assets over their estimated useful lives, which generally range from three to 40 years and from one to 14 years, respectively. The values of the above- and below-market leases are amortized and recorded as either an increase (in the case of below-market leases) or a decrease (in the case of above-market leases) to rental income over the remaining term of the associated lease, which generally range from one to 14 years. The value associated with in-place leases is amortized 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 amortized such below market lease value into rental income over the renewal period.
Investments in Unconsolidated Joint Ventures	'
	Investments in Unconsolidated Joint Ventures

	We account for our investments in unconsolidated joint ventures under the equity method of accounting as we exercise significant influence, but do not control the entity and are not considered to be the primary beneficiary. We consolidate the joint ventures that we control or which are VIEs and where we are considered to be the primary beneficiary. In all the joint ventures, the rights of the joint venture partner are both protective as well as participating. Unless the joint venture is determined to be a VIE and we are the primary beneficiary in a VIE, these participating rights preclude us from consolidating these joint ventures. This investment is recorded initially at cost, as investment in unconsolidated joint venture, and subsequently adjusted for equity in net income (loss) and cash contributions and distributions. Any difference between the carrying amount of this investment on our balance sheet and the underlying equity in net assets is amortized as an adjustment to equity in net income (loss) of unconsolidated joint venture over the lesser of the joint venture term or 10 years. Equity income (loss) from unconsolidated joint venture is allocated based on our ownership or economic interest in the joint venture. When a capital event (as defined in each joint venture agreement) such as a refinancing occurs, if return thresholds are met, future equity income will be allocated at our increased economic interest. We recognize incentive income from unconsolidated real estate joint ventures as income to the extent it is earned and not subject to a clawback feature. Distributions we receive from unconsolidated real estate joint ventures in excess of our basis in the investment are recorded as offsets to our investment balance if we remain liable for future obligations of the joint venture or may otherwise be committed to provide future additional financial support. In July 2012, we, along with our joint venture partner, sold One Court Square for $481.1 million, which included the assumption of $315.0 million of existing debt by the purchaser, and recognized a gain of $1.0 million on the sale of this property. In January 2013, we, along with our joint venture partner, acquired a preferred equity interest in an entity that holds an interest in a retail property located in Manhattan. See Note 4, “Preferred Equity and Other Investment.”
Revenue Recognition	'
	Revenue Recognition

	Rental revenue is recognized on a straight-line basis over the term of the lease. Rental revenue recognition commences when the tenant takes possession or controls the physical use of the leased space. In order for the tenant to take possession, the leased space must be substantially ready for its intended use. To determine whether the leased space is substantially ready for its intended use, management evaluates whether we are or the tenant is the owner of tenant improvements for accounting purposes. When management concludes that we are the owner of tenant improvements, rental revenue recognition begins when the tenant takes possession of the finished space, which is when such tenant improvements are substantially complete. In certain instances, when management concludes that we are not the owner (the tenant is the owner) of tenant improvements, rental revenue recognition begins when the tenant takes possession of or controls the space. When management concludes that we are the owner of tenant improvements for accounting purposes, we record amounts funded to construct the tenant improvements as a capital asset. For these tenant improvements, we record amounts reimbursed by tenants as a reduction of the capital asset. When management concludes that the tenant is the owner of tenant improvements for accounting purposes, we record our contribution towards those improvements as a lease incentive, which is included in deferred leasing costs on our consolidated balance sheets and amortized as a reduction to rental revenue on a straight-line basis over the term of the lease. The excess of rents recognized over amounts contractually due pursuant to the underlying leases are included in deferred rents receivable on the accompanying consolidated balance sheets. We establish, on a current basis, an allowance for future potential tenant credit losses, which may occur against this account. The balance reflected on the consolidated balance sheets is net of such allowance.

	In addition to base rent, our tenants also generally will pay their pro rata share of increases in real estate taxes and operating expenses for the building over a base year. In some leases, in lieu of paying additional rent based upon increases in building operating expenses, the tenant will pay additional rent based upon increases in the wage rate paid to porters over the porters’ wage rate in effect during a base year or increases in the consumer price index over the index value in effect during a base year. In addition, many of our leases contain fixed percentage increases over the base rent to cover escalations.

	Electricity is most often supplied by the landlord either on a sub-metered basis, or rent inclusion basis (i.e., a fixed fee is included in the rent for electricity, which may increase based upon increases in electricity rates or increases in electrical usage by the tenant). Base building services other than electricity (such as heat, air conditioning and freight elevator service during business hours, and base building cleaning) are typically provided at no additional cost, with the tenant paying additional rent only for services which exceed base building services or for services which are provided outside normal business hours.

	These escalations are based on actual expenses incurred in the prior calendar year. If the expenses in the current year are different from those in the prior year, then during the current year, the escalations will be adjusted to reflect the actual expenses for the current year.

	We record a gain on sale of real estate when title is conveyed to the buyer, subject to the buyer’s financial commitment being sufficient to provide economic substance to the sale and we have no substantial economic involvement with the buyer.

	Interest income on preferred equity investments is recognized over the life of the investment using the effective interest method and recognized on the accrual basis. Fees received in connection with loan commitments are deferred until the loan is funded and are then recognized over the term of the loan as an adjustment to yield. Anticipated exit fees, whose collection is expected, are also recognized over the term of the loan as an adjustment to yield. Fees on commitments that expire unused are recognized at expiration.

	Income recognition is generally suspended for preferred equity investments at the earlier of the date at which payments become 90 days past due or when, in the opinion of management, a full recovery of interest income and principal becomes doubtful. Interest income recognition is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. Interest is recorded as income on impaired loans only to the extent cash is received. Several of the preferred equity investments provide for accrual of interest at specified rates, which differ from current payment terms. Interest is recognized on such loans at the accrual rate subject to management’s determination that accrued interest and outstanding principal are ultimately collectible, based on the underlying collateral and operations of the borrower. If management cannot make this determination, interest income above the current pay rate is recognized only upon actual receipt.

	If we purchase a preferred equity investment at a discount, intend to hold it until maturity and expect to recover the full value of the investment, we accrete the discount into income as an adjustment to yield over the term of the investment. If we purchase a preferred equity investment at a discount with the intention of foreclosing on the collateral, we do not accrete the discount.
Income Taxes	'
	Income Taxes

	No provision has been made for income taxes in the accompanying consolidated financial statements since such taxes, if any, are the responsibility of the individual partners.
Reserve for Possible Credit Losses	'
	Reserve for Possible Credit Losses

	The expense for possible credit losses in connection with 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 relate to geographic trends and product diversification, the size of the portfolio and current economic conditions. Based upon these factors, we establish the provision for possible credit loss on each individual investment. When it is probable that we will be unable to collect all amounts contractually due, the investment is considered impaired.

	Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the net fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. The write-off of the reserve balance is called a charge-off. We continue to assess or adjust our estimates based on the circumstances of a loan and the underlying collateral. If additional information is obtained that reflects an increased recovery of our investment, we will adjust our reserves accordingly. We recorded no loan loss reserves during the three and nine months ended September 30, 2013 and 2012. During the three and nine months ended September 30, 2012, we recorded zero and $0.5 million, respectively, in recoveries in connection with the sale of one of our debt investments. This is included in loan loss reserves, net of recoveries in the accompanying consolidated statements of income.
Use of Estimates	'
	Use of Estimates

	The preparation of financial statements in conformity with U.S. GAAP 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, preferred equity investments and accounts receivable. We place our cash investments in excess of insured amounts with high quality financial institutions. The collateral securing our preferred equity investments is located in the New York Metropolitan area. See Note 4, “Preferred Equity and Other 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 rent and the costs associated with re-tenanting the space. Although the properties in our real estate portfolio are primarily located in Manhattan, we also have Suburban properties located in Westchester County and Connecticut. The tenants located in our buildings operate in various industries.
Reclassification	'
	Reclassification

	Certain prior year balances have been reclassified to conform to our current year presentation primarily in order to eliminate discontinued operations from income from continuing operations and to reclassify deferred origination fees from deferred income to preferred equity and other investment.
Accounting Standards Updates	'
	Accounting Standards Updates

	In February 2013, the FASB issued guidance on the presentation and disclosure of reclassification adjustments out of accumulated other comprehensive income, or AOCI. The standard requires an entity to present information about significant items reclassified out of AOCI by component either on the face of the statement where net income is presented or as a separate disclosure in the notes to financial statements. The guidance became effective for calendar year-end public companies beginning in the first quarter of 2013 and its adoption did not have a material impact on our consolidated financial statements.
