	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.
	As of March 31, 2014, we owned the following 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 properties:

	-1	The weighted average occupancy for commercial properties represents the total occupied square feet divided by total available rentable square feet.  The weighted average occupancy for residential properties represents the total occupied units divided by total available units.
	-2	As of March 31, 2014, we owned a building that was comprised of 270,132 square feet of retail space and 222,855 square feet of residential space. For the purpose of this report, we have included the building as part of retail properties and have shown the square footage under its respective classifications.
	As of March 31, 2014, we also held preferred equity investments with a book value of $413.7 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 March 31, 2014 and December 31, 2013, the consolidated results of their operations for the three months ended March 31, 2014 and 2013, their statement of capital for the three months ended March 31, 2014 and their statements of cash flows for the three months ended March 31, 2014 and 2013. 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. 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 March 31, 2014 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, 2014. 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, 2013.
	The balance sheet at December 31, 2013 has been derived from the audited financial statements as of 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 Investments." ROP's investments in majority-owned and controlled real estate joint ventures are reflected in the 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 a 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.
	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 us. 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 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 approve, among other things, the annual budget, receive a detailed monthly reporting package from us, meet on a quarterly basis to review the results of the joint venture, review and approve the joint venture's tax return before filing, and approve 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. We also evaluate our real estate properties for potential impairment when a real estate property has been classified as held for sale. Real estate assets held for sale are valued at the lower of their carrying value or fair value less costs to sell. We do not believe that the values of any of our consolidated properties or properties held for sale were impaired at March 31, 2014.
	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 range from one to 14 years. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off. The tenant improvements and origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). We assess fair value of the leases based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and market/economic conditions that may affect the property. To the extent acquired leases contain fixed rate renewal options that are below market and determined to be material, we amortize such below market lease value into rental income over the renewal period.
	We recognized increases of $4.7 million and $5.5 million in rental revenue for the three months ended March 31, 2014 and 2013, 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. We recognized an increase in interest expense for the amortization of the above-market rate mortgages assumed of $0.1 million for both the three months ended March 31, 2014 and 2013.
	In November 2013, we acquired a 492,987 square foot mixed-use residential and commercial property located at 315 West 33rd Street, New York, New York for $386.8 million. Based on our preliminary analysis of the purchase price, we had allocated $116.0 million and $270.8 million to land and building, respectively. During the three months ended March 31, 2014, we finalized the purchase price allocation based on third party appraisal and additional information about facts and circumstances that existed at the acquisition date and reclassified $33.2 million and $7.8 million to values for above- and in-place leases and below-market leases, respectively. These adjustments did not have a material impact to our consolidated statement of income for the three months ended March 31, 2014.
	The following summarizes our identified intangible assets (acquired above-market leases and in-place leases) and intangible liabilities (acquired below-market leases) as of March 31, 2014 and December 31, 2013 (in thousands):
		March 31, 2014			December 31, 2013
	Identified intangible assets (included in other assets):
	Gross amount	$	233,054		$	199,845
	Accumulated amortization	(151,331		)	(142,277		)
	Net	$	81,723		$	57,568
	Identified intangible liabilities (included in deferred revenue):
	Gross amount	$	406,927		$	399,088
	Accumulated amortization	(270,907		)	(262,642		)
	Net	$	136,020		$	136,446
	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 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 amount 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 accrued based on the outstanding principal amount and contractual terms of the instruments and when, in the opinion of management, it is deemed collectible. Some 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 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.
	Deferred origination fees, original issue discounts and loan origination costs, if any, are recognized as a reduction to the interest income over the terms of the related investments using the effective interest method. 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. Discounts or premiums associated with the purchase of loans are amortized or accreted into interest income as a yield adjustment on the effective interest method based on expected cashflows through the expected maturity date of the related investment. 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. Anticipated exit fees, whose collection is expected, are also recognized over the term of the loan as an adjustment to yield.
	Preferred equity investments are placed on a non-accrual status 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 becomes doubtful. Interest income recognition on any non-accrual preferred equity investment is resumed when such non-accrual preferred equity investment 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.
	We may syndicate a portion of the loans that we originate or sell these loans individually. When a transaction meets the criteria of sale accounting, we derecognize the loan sold and recognize gain or loss based on the difference between the sales price and the carrying value of the loan sold. Any related unamortized deferred origination fees, loan origination costs, discounts or premiums at the time of sale are recognized as an adjustment to the gain or loss on sale, which is included in investment income on the consolidated statement of income. Any fees received at the time of sale or syndication are recognized as part of investment income.
	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. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If the additional information obtained reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during the three months ended March 31, 2014 and 2013.
	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.
	Fair Value Measurements
	See Note 8, "Fair Value Measurements."
	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 New York City. 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 5.1% and 3.4% of our share of annualized cash rent, respectively, no other tenant in our portfolio accounted for more than 3.3% of our annualized cash rent, including our share of joint venture annualized cash rent for the three months ended March 31, 2014. For the three months ended March 31, 2014, 20.2%, 9.9%, 9.9%, 8.8% and 8.7% of our annualized cash rent was attributable to 1185 Avenue of the Americas, 919 Third Avenue, 750 Third Avenue, 1350 Avenue of the Americas and 810 Seventh Avenue, 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.
	Accounting Standards Updates
	In April 2014, the FASB issued new guidance on reporting discontinued operations which raises the threshold for disposals to qualify as discontinued operations. The guidance also allows us to have a significant continuing involvement and continuing cash flows with the discontinued operations. Additionally, the guidance requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. The guidance is effective for calendar year public companies beginning in the first quarter of 2015 and is to be applied on a prospective basis for new disposals. Early adoption of the guidance is permitted. The Company will adopt this standard beginning in the first quarter of 2015. The adoption of this guidance will change the presentation of discontinued operations but will not have a material impact on our consolidated financial statements.

	2012 Credit Facility
	In March 2014, we entered into an amendment to the $1.6 billion credit facility entered into by the Company in November 2012, or the 2012 credit facility, which, among other things, increased the term loan portion of the 2012 credit facility by $383.0 million to $783.0 million, decreased the interest-rate margin applicable to the term loan facility by 25 basis points and extended the maturity of the term loan portion of the facility from March 30, 2018 to June 30, 2019. The 2012 credit facility, as amended, consists of a $1.2 billion revolving credit facility, or the revolving credit facility, and a $783.0 million term loan facility, 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 existing lenders and other financial institutions.
	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) 95 basis points to 190 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 March 31, 2014, the applicable spread was 145 basis points for revolving credit facility and 140 basis points for the term loan facility. At March 31, 2014, the effective interest rate was 1.62% for the revolving credit facility and 1.84% for the term loan facility. We are required to pay quarterly in arrears a 15 to 35 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to our senior unsecured long term indebtedness. As of March 31, 2014, the facility fee was 30 basis points. At March 31, 2014, we had $71.6 million of outstanding letters of credit and $783.0 million outstanding under the term loan facility, with total undrawn capacity of $1.1 billion under the revolving credit facility.
	In connection with the amendment of the 2012 credit facility, we incurred debt origination and other loan costs of $2.8 million. We evaluated the modification pursuant to ASC 470 and determined that the terms of the amendment were not substantially different from the terms of the previous 2012 credit facility. As a result, these deferred costs and the unamortized balance of the costs previously incurred are amortized through the extended maturity date of the term loan facility.
	We, SL Green and the Operating Partnership are all borrowers jointly and severally obligated under the 2012 credit facility. No other subsidiary of SL Green is an obligor under the 2012 credit facility.
	The 2012 credit facility includes certain restrictions and covenants (see Restrictive Covenants below).

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.

Fair Value Disclosures [Abstract]	'
Fair Value Measurements	'
	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 sheets 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 March 31, 2014 and December 31, 2013 (in thousands):
		March 31, 2014				December 31, 2013
		Carrying Value		Fair Value		Carrying Value		Fair Value

	____________________________________
	-1	Preferred equity investments had an estimated fair value ranging from $400.0 million to $460.0 million as of March 31, 2014. As of December 31, 2013, preferred equity investments had an estimated fair value of 400.0 million.
	Disclosure about fair value of financial instruments was based on pertinent information available to us as of March 31, 2014 and December 31, 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.

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 March 31, 2014, the Company had designated an interest swap agreement on $30.0 million of the 2012 credit facility. The following table summarizes the notional and fair value of our derivative financial instrument at March 31, 2014 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 March 31, 2014 and December 31, 2013, 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 $2.6 million and $2.7 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.

The following table presents the effect of our derivative financial instruments that are designated and qualify as hedging instruments on the consolidated statements of comprehensive income for the three months ended March 31, 2014 and 2013 (in thousands):

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. Our affiliate earned $0.8 million from profit participation for both the three months ended March 31, 2014 and 2013. We recorded expenses of $0.9 million and $1.3 million for the three months ended March 31, 2014 and 2013, 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. Allocated expenses were $1.8 million for both the three months ended March 31, 2014 and 2013.

	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 investments. We evaluate real estate performance and allocate resources based on earnings contribution to income from continuing operations.
	The primary sources of revenue from our real estate portfolio are generated from tenant rents, 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 Investments," for additional details on our preferred equity investments.
	Selected results of operations for the three months ended March 31, 2014 and 2013 and selected asset information as of March 31, 2014 and December 31, 2013, regarding our operating segments are as follows (in thousands):
		Real Estate		Preferred		Total

	31-Dec-13	5,216,087		370,532		5,586,619
	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 for the preferred equity segment. Interest costs for the preferred equity segment are imputed assuming 100% leverage at our 2012 credit facility borrowing cost. We also allocate loan loss reserves, net of recoveries, and transaction related costs to the preferred equity segment. We do not allocate marketing, general and administrative expenses to the preferred equity 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 Investments." ROP's investments in majority-owned and controlled real estate joint ventures are reflected in the 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 a 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.
	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 us. 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 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 approve, among other things, the annual budget, receive a detailed monthly reporting package from us, meet on a quarterly basis to review the results of the joint venture, review and approve the joint venture's tax return before filing, and approve 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. We also evaluate our real estate properties for potential impairment when a real estate property has been classified as held for sale. Real estate assets held for sale are valued at the lower of their carrying value or fair value less costs to sell. We do not believe that the values of any of our consolidated properties or properties held for sale were impaired at March 31, 2014.
	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 range 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.
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 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 amount 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 accrued based on the outstanding principal amount and contractual terms of the instruments and when, in the opinion of management, it is deemed collectible. Some 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 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.
	Deferred origination fees, original issue discounts and loan origination costs, if any, are recognized as a reduction to the interest income over the terms of the related investments using the effective interest method. 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. Discounts or premiums associated with the purchase of loans are amortized or accreted into interest income as a yield adjustment on the effective interest method based on expected cashflows through the expected maturity date of the related investment. 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. Anticipated exit fees, whose collection is expected, are also recognized over the term of the loan as an adjustment to yield.
	Preferred equity investments are placed on a non-accrual status 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 becomes doubtful. Interest income recognition on any non-accrual preferred equity investment is resumed when such non-accrual preferred equity investment 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.
	We may syndicate a portion of the loans that we originate or sell these loans individually. When a transaction meets the criteria of sale accounting, we derecognize the loan sold and recognize gain or loss based on the difference between the sales price and the carrying value of the loan sold. Any related unamortized deferred origination fees, loan origination costs, discounts or premiums at the time of sale are recognized as an adjustment to the gain or loss on sale, which is included in investment income on the consolidated statement of income. Any fees received at the time of sale or syndication are recognized as part of investment income.
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. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If the additional information obtained reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during the three months ended March 31, 2014 and 2013.
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.
Fair Value Measurements	'
	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 sheets 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.
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 New York City. 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.
Accounting Standards Updates	'
	Accounting Standards Updates
	In April 2014, the FASB issued new guidance on reporting discontinued operations which raises the threshold for disposals to qualify as discontinued operations. The guidance also allows us to have a significant continuing involvement and continuing cash flows with the discontinued operations. Additionally, the guidance requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. The guidance is effective for calendar year public companies beginning in the first quarter of 2015 and is to be applied on a prospective basis for new disposals. Early adoption of the guidance is permitted.
