ITEM 1.    BUSINESS

General

Reckson Operating Partnership, L.P., or ROP, commenced operations on June 2, 1995. The sole general partner of ROP is Wyoming Acquisition GP LLC., or WAGP, a wholly-owned subsidiary of SL Green Operating Partnership, L.P., or the Operating Partnership. The sole limited partner of ROP is the Operating Partnership.

ROP is engaged in the business of owning, managing, leasing, acquiring and repositioning of commercial and residential real estate properties, principally office properties, and also owns land for future development, located in New York City, Westchester County, Connecticut and New Jersey, which collectively is also known as the New York Metropolitan area.

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 2015, SL Green transferred two properties and SL Green's tenancy in common interest in a fee interest with a total value of $395.0 million to ROP. Additionally, in 2015, SL Green transferred one entity that held debt investments and financing receivables with an aggregate carrying value of $1.7 billion to ROP. During 2014, SL Green transferred five properties with a total value aggregating $884.3 million to ROP. These transfers were made to further diversify ROP's portfolio. Under the Business Combinations guidance (Accounting Standard Codification 805-50), these transfers 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 values and were 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 years have been retrospectively adjusted to furnish comparative information.

As of December 31, 2015, we owned the following interests in properties in the New York Metropolitan area, primarily in midtown Manhattan. Our investments in the New York Metropolitan area also include investments in Brooklyn, Westchester County, Connecticut and New Jersey, which are collectively known as the Suburban properties:

____________________________________________________________________

(1) The weighted average occupancy represents the total occupied square feet divided by total available rentable square feet.

(2) As of December 31, 2015, we owned a building that was comprised of approximately 270,132 square feet of retail space and approximately 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.

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

As of December 31, 2015, we also held debt, preferred equity and other investments with a book value of $1.8 billion.

Our corporate offices are located in midtown Manhattan at 420 Lexington Avenue, New York, New York 10170. As of December 31, 2015, SL Green's corporate staff, inclusive of our staff, consisted of 296 persons, including 187 professionals

ITEM 1A.  RISK FACTORS

We encourage you to read "Item 1A—Risk Factors" in SL Green and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2015.

Declines in the demand for office space in New York City, and in particular midtown Manhattan, as well as our Suburban markets, including Westchester County, Connecticut and New Jersey, could adversely affect the value of our real estate portfolio and our results of operations and, consequently, our ability to service current obligations and make distributions to SL Green.

The majority of our property holdings are comprised of commercial office properties located in midtown Manhattan. Our property holdings also include a number of retail properties and a multifamily residential property. As a result, our business is dependent on the condition of the New York City economy in general and the market for office space in midtown Manhattan in particular. Future weakness and uncertainty in the New York City economy could materially reduce the value of our real estate portfolio and our rental revenues, and thus adversely affect our cash flow and our ability to service current debt and make distributions to SL Green. Similarly, future weakness and uncertainty in our suburban markets could adversely affect our cash flow and our ability to service current debt and to make distributions to SL Green.

We believe that job creation in the financial and professional services industries in New York City impacts our overall financial performance.  Both new leasing activity and overall asking rents could be negatively impacted by declining rates of job creation in the current or future periods.

We may be unable to renew leases or relet space as leases expire.

If our tenants decide not to renew their leases upon their expiration, we may not be able to relet the space. Even if tenants do renew or we can relet the space, the terms of a renewal or new lease, taking into account among other things, the cost of improvements to the property and leasing commissions, may be less favorable than the terms in the expired leases. As of December 31, 2015, approximately 4.2 million square feet, representing approximately 38.9% of the rentable square feet, are scheduled to expire by December 31, 2020 at our consolidated properties and as of December 31, 2015, these leases had annualized escalated rent totaling $253.0 million. We also have leases with termination options beyond 2020. In addition, changes in space utilization by our tenants may impact our ability to renew or relet space without the need to incur substantial costs in renovating or redesigning the internal configuration of the relevant property. If we are unable to promptly renew the leases or relet the space at similar rates or if we incur substantial costs in renewing or reletting the space, our cash flow and ability to service debt obligations and make distributions to SL Green could be adversely affected.

We face significant competition for tenants.

The leasing of real estate is highly competitive. The principal competitive factors are rent, location, services provided and the nature and condition of the property to be leased. We directly compete with all owners, developers and operators of similar space in the areas in which our properties are located.

Our commercial office properties are concentrated in highly developed areas of midtown Manhattan and certain Suburban central business districts, or CBDs. Manhattan is the largest office market in the United States. The number of competitive office properties in Manhattan and CBDs in which our Suburban properties are located, which may be newer or better located than our properties, could have a material adverse effect on our ability to lease office space at our properties, and on the effective rents we are able to charge.

The expiration of long term leases or operating sublease interests where we do not own a fee interest in the land could adversely affect our results of operations.

Our interests in 461 Fifth Avenue, 625 Madison Avenue, 1185 Avenue of the Americas and 711 Third Avenue all in Manhattan, and 1055 Washington Boulevard, Stamford, Connecticut, are entirely or partially comprised of either long-term leasehold or operating sublease interests in the land and the improvements, rather than by ownership of fee interest in the land. We have the ability to acquire the fee position at 461 Fifth Avenue for a fixed price on a specific date.

The average remaining term of these long-term leases as of December 31, 2015, including our unilateral extension rights on each of the properties, is 31 years. Pursuant to the leasehold arrangements, we, as tenants under the operating sublease, perform the functions traditionally performed by landlords with respect to our subtenants. We are responsible for not only collecting rent from our subtenants, but also maintaining the property and paying expenses relating to the property. Our share of annualized cash rents of the commercial office properties held through long-term leases or operating sublease interests at December 31, 2015 totaled $191.2 million, or 32.7%, of our share of total annualized cash rent for office properties. Unless we purchase a fee interest in the underlying land or extend the terms of these leases prior to their expiration, we will lose our right to operate these properties upon expiration of the leases, which could adversely affect our financial condition and results of operations.

5

Adverse economic and geopolitical conditions in general and the commercial office markets in the New York Metropolitan area in particular could have a material adverse effect on our results of operations and financial condition and, consequently, our ability to service debt obligations and make distributions to SL Green.

Our business may be affected by volatility in the financial and credit markets and other market or economic challenges experienced by the U.S. economy or the real estate industry as a whole. Future periods of economic weakness could result in reduced access to credit and/or wider credit spreads. Economic uncertainty, including concern about growth and the stability of the markets generally may lead many lenders and institutional investors to reduce, and in some cases, cease to provide funding to borrowers, which could adversely affect our liquidity and financial condition, and the liquidity and financial condition of our tenants. Our business may also be adversely affected by local economic conditions, as substantially all of our revenues are derived from our properties located in the New York Metropolitan area, particularly in Manhattan, Westchester County, Connecticut and New Jersey. Because our portfolio consists primarily of commercial office buildings, located principally in midtown Manhattan, as compared to a more diversified real estate portfolio, if economic conditions deteriorate, then our results of operations, financial condition and ability to service current debt and to make distributions to SL Green may be adversely affected. Specifically, our business may be affected by the following conditions:

• significant job losses or declining rates of job creation which may decrease demand for our office space, causing market rental rates and property values to be negatively impacted;

• our ability to borrow on terms and conditions that we find acceptable may be limited, which could reduce our ability to pursue acquisition and development opportunities and refinance existing debt, reducing our returns from both our existing operations and our acquisition and development activities and increasing our future interest expense; and

• reduced values of our properties, which may limit our ability to dispose of assets at attractive prices or to obtain debt financing secured by our properties and may reduce the availability of unsecured loans.

We rely on five large properties for a significant portion of our revenue.

Five of our properties, 1185 Avenue of the Americas, 810 Seventh Avenue, 919 Third Avenue, 625 Madison Avenue and 750 Third Avenue, accounted for 48.5% of our total annualized cash rent for office properties, and 1185 Avenue of the Americas alone accounted for 15.4% of our total annualized cash rent for office properties as of December 31, 2015. Our revenue and cash available to service debt obligations and to make distributions to SL Green would be materially adversely affected if the ground lease for the 1185 Avenue of the Americas property were terminated for any reason or if any of these properties were materially damaged or destroyed. Additionally, our revenue and cash available to service debt obligations and make distributions to SL Green would be materially adversely affected if tenants at these properties fail to timely make rental payments due to adverse financial conditions or otherwise, default under their leases or file for bankruptcy or become insolvent.

Our results of operations rely on major tenants and insolvency or bankruptcy of these or other tenants could adversely affect our results of operations.

Giving effect to leases in effect as of December 31, 2015 for consolidated properties, as of that date, our five largest tenants, based on annualized cash rent, accounted for 15.8% of our share of total annualized cash rent for office properties, with three tenants, Ralph Lauren Corporation, Debevoise & Plimpton, LLP and News America Incorporated, accounting for 4.5%, 3.8% and 2.6% of our share of total annualized cash rent for office properties, respectively. Our business and results of operations would be adversely affected if any of our major tenants became insolvent, declared bankruptcy, or otherwise refused to pay rent in a timely fashion or at all. In addition, if current conditions in the industries in which our tenants are concentrated deteriorate, we may experience increases in past due accounts, defaults, lower occupancy and reduced effective rents across tenants in such industries, which could in turn have an adverse effect on our business and results of operations.

Leasing office space to smaller and growth-oriented businesses could adversely affect our cash flow and results of operations.

Some of the tenants in our properties are smaller, growth-oriented businesses that may not have the financial strength of larger corporate tenants. Smaller companies generally experience a higher rate of failure than larger businesses. Growth-oriented firms may also seek other office space as they develop. Leasing office space to these companies could create a higher risk of tenant defaults, turnover and bankruptcies, which could adversely affect our cash flow and results of operations.

We may suffer adverse consequences if our revenues decline since our operating costs do not necessarily decline in proportion to our revenue.

We earn a significant portion of our income from renting our properties. Our operating costs, however, do not necessarily fluctuate in direct proportion to changes in our rental revenue. As a result, our costs will not necessarily decline even if our revenues do. In such event, we may be forced to borrow to cover our costs, we may incur losses or we may not have cash available to service our debt obligations and make distributions to SL Green.

We face risks associated with property acquisitions.

We may acquire interests in properties, individual properties and portfolios of properties, including large portfolios that could significantly increase our size and alter our capital structure. Our acquisition activities may be exposed to, and their success may be adversely affected by, the following risks:

• we may be unable to meet required closing conditions;

• we may be unable to finance acquisitions and developments of properties on favorable terms or at all;

• we may be unable to lease our acquired properties on the same terms or to the same level of occupancy as our existing properties;

• acquired properties may fail to perform as we expected;

• we may expend funds on, and devote management time to, acquisition opportunities which we do not complete, which may include non-refundable deposits;

• our estimates of the costs we incur in renovating, improving, developing or redeveloping acquired properties may be inaccurate;

• we may not be able to obtain adequate insurance coverage for acquired properties; and

• we may be unable to quickly and efficiently integrate new acquisitions and developments, particularly acquisitions of portfolios of properties, into our existing operations, and therefore our results of operations and financial condition could be adversely affected.

We may acquire properties subject to both known and unknown liabilities and without any recourse, or with only limited recourse to the seller. As a result, if a liability were asserted against us arising from our ownership of those properties, we might have to pay substantial sums to settle it, which could adversely affect our cash flow. Unknown liabilities with respect to properties acquired might include:

• claims by tenants, vendors or other persons arising from dealing with the former owners of the properties;

• liabilities incurred in the ordinary course of business;

• claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties; and

• liabilities for clean-up of undisclosed environmental contamination.

Competition for acquisitions may reduce the number of acquisition opportunities available to us and increase the costs of those acquisitions.

We may acquire properties when we are presented with attractive opportunities. We may face competition for acquisition opportunities from other investors, particularly those investors who are willing to incur more leverage, and this competition may adversely affect us by subjecting us to the following risks:

• an inability to acquire a desired property because of competition from other well-capitalized real estate investors, including publicly traded and privately held REITs, private real estate funds, domestic and foreign financial institutions, life insurance companies, sovereign wealth funds, pension trusts, partnerships and individual investors; and

• an increase in the purchase price for such acquisition property.

If we are unable to successfully acquire additional properties, our ability to grow our business could be adversely affected. In addition, increases in the cost of acquisition opportunities could adversely affect our results of operations.

We are subject to risks that affect the retail environment.

Approximately 3.6% of our share of total annualized cash rent is generated by retail properties, principally in Manhattan. As a result, we are subject to risks that affect the retail environment generally, including the level of consumer spending, consumer confidence and levels of tourism in Manhattan. These factors could adversely affect the financial condition of our retail tenants and the willingness of retailers to lease space in our retail properties, which could in turn have an adverse effect on our business and results of operations.

The occurrence of terrorist attacks may adversely affect the value of our properties and our ability to generate cash flow.

Our operations are primarily concentrated in the New York Metropolitan area. In the aftermath of a terrorist attack or other acts of terrorism or war, tenants in the New York Metropolitan area may choose to relocate their business to less populated, lower-profile areas of the United States that those tenants believe are not as likely to be targets of future terrorist activity. In addition,

7

economic activity could decline as a result of terrorist attacks or other acts of terrorism or war, or the perceived threat of such acts. Each of these impacts could in turn trigger a decrease in the demand for space in the New York Metropolitan area, which could increase vacancies in our properties and force us to lease our properties on less favorable terms. Furthermore, we may also experience increased costs in relation to security equipment and personnel. As a result, the value of our properties and our results of operations could materially decline.

Potential losses may not be covered by insurance.

ROP is insured through a program administered by SL Green. SL Green maintains “all-risk” property and rental value coverage (including coverage regarding the perils of flood, earthquake and terrorism) within three property insurance portfolios and liability insurance. This includes ROP assets. The first property portfolio maintains a blanket limit of $950.0 million per occurrence, including terrorism, for the majority of the New York City properties in our portfolio, which expires on December 31, 2017. The second portfolio maintains a limit of $1.5 billion per occurrence, including terrorism, for several New York City properties and the majority of the Suburban properties and expires on December 31, 2017. Each policy includes $100.0 million of flood coverage, with a lower sublimit for locations in high hazard flood zones. A third blanket property policy covers most of SL Green's residential assets and maintains a limit of $380.1 million per occurrence, including terrorism, for our residential properties and expires January 31, 2018. SL Green maintains two liability policies which cover all our properties and provide limits of $201.0 million per occurrence and in the aggregate per location. The liability policies expire on October 31, 2016 and January 31, 2017 and cover our commercial and residential assets, respectively. Additional coverage may be purchased on a stand-alone basis for certain assets.

SL Green's wholly-owned taxable REIT subsidiary, Belmont Insurance Company, or Belmont, acts as a captive insurance company and as one of the elements of our overall insurance program. Belmont was formed in an effort to, among other reasons, stabilize to some extent the impact on us of fluctuations of insurance market conditions. Belmont is licensed in New York to write Terrorism, NBCR (nuclear, biological, chemical, and radiological), General Liability, Environmental Liability, Flood, and D&O coverage. As long as SL Green owns Belmont, SL Green is responsible for its liquidity and capital resources, and the accounts of Belmont are part of SL Green's consolidated financial statements. If we experience a loss and Belmont is required to pay a claim under our insurance policy, SL Green would ultimately record the loss to the extent of Belmont’s required payment. Belmont is not reinsured by a third-party. Therefore, insurance coverage provided by Belmont should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance.

On January 12, 2015, the Terrorism Risk Insurance Program Reauthorization and Extension Act of 2007 (TRIPRA) (formerly the Terrorism Risk Insurance Act) was reauthorized through December 31, 2020 pursuant to the Terrorism Insurance Program Reauthorization and Extension Act of 2015. TRIPRA extends the federal Terrorism Insurance Program that requires insurance companies to offer terrorism coverage and provides for compensation for insured losses resulting from acts of certified terrorism, subject to the current program trigger of $100.0 million, which will increase by $20.0 million per annum, commencing December 31, 2015. Our debt instruments, consisting of mortgage loans secured by our properties (which are generally non-recourse), mezzanine loans, ground leases, 2012 credit facility, senior unsecured notes and other corporate obligations, contain customary covenants requiring us to maintain insurance. Although we believe that we currently maintain sufficient insurance coverage to satisfy these obligations, there is no assurance that in the future we will be able to procure coverage at a reasonable cost. In such instances, there can be no assurance that the lenders or ground lessors under these instruments will not take the position that a total or partial exclusion from “all-risk” insurance coverage for losses due to, for example, terrorist acts is a breach of these debt and ground lease instruments allowing the lenders or ground lessors to declare an event of default and accelerate repayment of debt or recapture of ground lease positions. In addition, if lenders require greater coverage that we are unable to obtain at commercially reasonable rates, we may incur substantially higher insurance premiums or our ability to finance our properties and expand our portfolio may be adversely impacted.

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

We face possible risks associated with natural disasters and the physical effects of climate change.

We are subject to the risks associated with natural disasters and the physical effects of climate change, which can include storms, hurricanes and flooding, any of which could have a material adverse effect on our properties, operations and business. To the extent climate change causes changes in weather patterns, our markets could experience increases in storm intensity and rising sea-levels. Over time, these conditions could result in declining demand for office space in our buildings or the inability of us to operate the buildings at all. Climate change may also have indirect effects on our business by increasing the cost of (or making unavailable) property insurance on terms we find acceptable, increasing the cost of energy at our properties and requiring us to

8

expend funds as we seek to repair and protect our properties against such risks. There can be no assurance that climate change will not have a material adverse effect on our properties, operations or business.

Debt financing, financial covenants, degree of leverage, and increases in interest rates could adversely affect our economic performance.

Scheduled debt payments could adversely affect our results of operations.

Cash flow could be insufficient to make distributions to SL Green and meet the payments of principal and interest required under our current mortgages, our 2012 credit facility, our senior unsecured notes, our debentures and indebtedness outstanding at our unconsolidated joint venture property. We, SL Green, and the Operating Partnership are all borrowers jointly and severally obligated under the 2012 credit facility.

The total principal amount of our outstanding consolidated indebtedness was $3.8 billion as of December 31, 2015, consisting of $1.9 billion under our 2012 credit facility, which is inclusive of our $933.0 million term loan, $1.1 billion under our senior unsecured notes and $753.4 million of non-recourse mortgages and loans payable on one of our consolidated properties and certain debt and preferred equity investments. In addition, we could increase the amount of our outstanding consolidated indebtedness in the future, in part by borrowing under the revolving credit facility portion of our 2012 credit facility. The $1.6 billion revolving credit facility portion of our 2012 credit facility currently matures in March 2020, which includes two six-month extension options. In the first quarter of 2015 we modified and extended the revolving credit facility from March 2018 to March 2020 and reduced the margin by 25 basis points. This modification took effect in the first quarter of 2015. As of December 31, 2015, the total principal amount of non-recourse indebtedness outstanding at our unconsolidated joint venture property was $141.0 million.

If we are unable to make payments under our 2012 credit facility, all amounts due and owing at such time shall accrue interest at a rate equal to 2% higher than the rate at which each draw was made. If we are unable to make payments under our senior unsecured notes, the principal and unpaid interest will become immediately payable. If a property is mortgaged to secure payment of indebtedness and we are unable to meet mortgage payments, the mortgagee could foreclose on the property, resulting in loss of income and asset value. Foreclosure on mortgaged properties or an inability to make payments under our 2012 credit facility or our senior unsecured notes could trigger defaults under the terms of our other financings, making such financings at risk of being declared immediately payable, and would have a negative impact on our financial condition and results of operations.

We may not be able to refinance existing indebtedness, which may require substantial principal payments at maturity. In 2016, $253.4 million under the master repurchase agreement facility and $255.3 million of our senior unsecured notes will mature. At the present time, we intend to exercise extension options, repay or refinance the debt associated with our properties on or prior to their respective maturity dates. At the time of refinancing, prevailing interest rates or other factors, such as the possible reluctance of lenders to make commercial real estate loans may result in higher interest rates. Increased interest expense on the extended or refinanced debt would adversely affect cash flow and our ability to service debt obligations and make distributions to SL Green. If any principal payments due at maturity cannot be repaid, refinanced or extended, our cash flow will not be sufficient to repay maturing or accelerated debt.

Financial covenants could adversely affect our ability to conduct our business.

The mortgages on our properties generally contain customary negative covenants that limit our ability to further mortgage the properties, to enter into material leases without lender consent or materially modify existing leases, among other things. In addition, our 2012 credit facility and senior unsecured notes contain restrictions and requirements on our method of operations. Our 2012 credit facility and our unsecured notes also require us to maintain designated ratios, including but not limited to, total debt-to-assets, debt service coverage and unencumbered assets-to-unsecured debt. These restrictions could adversely affect operations (including reducing our flexibility and our ability to incur additional debt), our ability to service debt obligations and our ability make to distributions to SL Green.

Rising interest rates could adversely affect our cash flow.

Advances under our 2012 credit facility and our master repurchase agreement facility bear interest at a variable rate. Our consolidated variable rate borrowings totaled $2.2 billion at December 31, 2015. In addition, we could increase the amount of our outstanding variable rate debt in the future, in part by borrowing additional amounts under our 2012 credit facility, which consisted of a $1.6 billion revolving credit facility and $933.0 million term loan. Borrowings under our revolving credit facility and term loan bore interest at the 30-day LIBOR, plus spreads of 125 basis points and 140 basis points, respectively, at December 31, 2015. As of December 31, 2015, borrowings under our 2012 credit facility bore weighted average interest at 1.56%. We may incur indebtedness in the future that also bears interest at a variable rate or may be required to refinance our debt at higher rates. At December 31, 2015, a hypothetical 100 basis point increase in interest rates across each of our consolidated variable interest rate instruments would increase our annual interest costs by approximately $10.0 million. Our joint ventures may also incur variable rate debt and face similar risks. Accordingly, increases in interest rates could adversely affect our results of operations and financial conditions and our ability to continue to service debt and make distributions to SL Green.

Failure to hedge effectively against interest rate changes may adversely affect results of operations.

The interest rate hedge instruments we use to manage some of our exposure to interest rate volatility involve risk and counterparties may fail to honor their obligations under these arrangements. In addition, these arrangements may not be effective in reducing our exposure to interest rate changes and when existing interest rate hedges terminate, we may incur increased costs in putting in place further interest rate hedges. Failure to hedge effectively against interest rate changes may adversely affect our results of operations.

Increases in our level of indebtedness could adversely affect our cash flow.

SL Green considers its business as a whole in determining the amount of leverage of itself and its subsidiaries, including us. SL Green also considers other factors in making decisions regarding the incurrence of indebtedness, such as the purchase price of properties to be acquired with debt financing, the estimated market value of our properties upon refinancing and the ability of particular properties and our business as a whole to generate cash flow to cover expected debt service. Our organizational documents do not contain any limitation on the amount of indebtedness we may incur. As a result, if we become more highly leveraged, an increase in debt service could adversely affect cash available for distributions to SL Green and could increase the risk of default on our indebtedness.

A downgrade in our credit ratings could materially adversely affect our business and financial condition.

Our credit rating and the credit ratings assigned to our debt securities could change based upon, among other things, our results of operations and financial condition. These ratings are subject to ongoing evaluation by credit rating agencies, and any rating could be changed or withdrawn by a rating agency in the future if, in its judgment, circumstances warrant such action. Moreover, these credit ratings are not recommendations to buy, sell or hold our securities. If any of the credit rating agencies that have rated our securities downgrades or lowers its credit rating, or if any credit rating agency indicates that it has placed any such rating on a “watch list” for a possible downgrading or lowering, or otherwise indicates that its outlook for that rating is negative, such action could have a material adverse effect on our costs and availability of funding, which could in turn have a material adverse effect on our financial condition, results of operations, cash flows, the trading price of our securities and our ability to service debt obligations and make distributions to SL Green.

Debt and preferred equity investments could cause us to incur expenses, which could adversely affect our results of operations.

We held first mortgages, mezzanine loans, junior participations and preferred equity interests in 41 investments with an aggregate net book value of $1.7 billion at December 31, 2015. Some of these instruments may be recourse in whole or in part to their sponsors, while others are limited to the collateral securing the loan. In the event of a default under these obligations, we may have to take possession of the collateral securing these interests. Borrowers may, among other things, contest enforcement of foreclosure or other remedies, seek bankruptcy protection against such enforcement and/or bring claims for lender liability in response to actions to enforce their obligations to us. Declines in the value of the property may prevent us from realizing an amount equal to our investment upon foreclosure or realization even if we make substantial improvements or repairs to the underlying real estate in order to maximize such property's investment potential. In addition, we may invest in mortgage-backed securities and other marketable securities.

We maintain and regularly evaluate the need for reserves to protect against potential future losses. Our reserves reflect management's judgment of the probability and severity of losses and the value of the underlying collateral. We cannot be certain that our judgment will prove to be correct and that our reserves will be adequate over time to protect against future losses because of unanticipated adverse changes in the economy or events adversely affecting specific properties, assets, tenants, borrowers, industries in which our tenants and borrowers operate or markets in which our tenants and borrowers or their properties are located. As of December 31, 2015, we had no recorded reserves for possible credit losses. If our reserves for credit losses prove inadequate, we could suffer losses which would have a material adverse effect on our financial performance and our ability to service debt obligations and make distributions to SL Green.

Joint investments could be adversely affected by our lack of sole decision-making authority and reliance upon a co-venturer's financial condition.

We co-invest with third parties through partnerships, joint ventures, co-tenancies or other structures, and by acquiring non-controlling interests in, or sharing responsibility for managing the affairs of, a property, partnership, joint venture, co-tenancy or other entity. Therefore, we may not be in a position to exercise sole decision-making authority regarding such property, partnership, joint venture or other entity. Investments in partnerships, joint ventures, or other entities may involve risks not present were a third party not involved, including the possibility that our partners, co-tenants or co-venturers might become bankrupt or otherwise fail to fund their share of required capital contributions. Additionally, our partners or co-venturers might at any time have economic or other business interests or goals which are competitive or inconsistent with our business interests or goals. These investments may also have the potential risk of impasses on decisions such as a sale, because neither we, nor the partner, co-tenant or co-

10

venturer would have full control over the partnership or joint venture. In addition, we may in specific circumstances be liable for the actions of our third-party partners, co-tenants or co-venturers.

Certain of our joint venture agreements contain terms in favor of our partners that could have an adverse effect on the value of our investments in the joint ventures.

Each of our joint venture agreements has been individually negotiated with our partner in the joint venture and, in some cases, we have agreed to terms that are more favorable to our partner in the joint venture than to us. For example, our partner may be entitled to a specified portion of the profits of the joint venture before we are entitled to any portion of such profits. We may also enter into similar arrangements in the future. These rights may permit our partner in a particular joint venture to obtain a greater benefit from the value or profits of the joint venture than us, which could have an adverse effect on the value of our investment in the joint venture and on our financial condition and results of operations.

We may incur costs to comply with environmental and health and safety laws.

We are subject to various federal, state and local environmental and health and safety laws which change from time to time. These laws regulate, among other things, air and water quality, our use, storage, disposal and management of hazardous substances and wastes and can impose liability on current and former property owners or operators for the clean-up of certain hazardous substances released on a property and any associated damage to natural resources without regard to whether the release was in compliance with law or whether it was caused by, or known to, the property owner or operator. The presence of hazardous substances on our properties may adversely affect occupancy and our ability to develop or sell or borrow against those properties. In addition to potential liability for clean-up costs, private plaintiffs may bring claims for personal injury, property damage or for similar reasons. Various laws also impose liability for the clean-up of contamination at any facility (e.g., a landfill) to which we have sent hazardous substances for treatment or disposal, without regard to whether the materials were transported, treated and disposed in accordance with law. Being held responsible for such a clean-up could result in significant cost to us and have a material adverse effect on our financial condition and results of operations.

We may incur significant costs complying with the Americans with Disabilities Act and other regulatory and legal requirements.

Our properties may be subject to risks relating to current or future laws including laws benefiting disabled persons, and other state or local zoning, construction or other regulations. These laws may require significant property modifications in the future which could result in fines being levied against us in the future. The occurrence of any of these events could have an adverse impact on our cash flows and ability to service debt and make distributions to SL Green.

Under the Americans with Disabilities Act, or ADA, all public accommodations must meet federal requirements related to access and use by disabled persons. Additional federal, state and local laws also may require modifications to our properties, or restrict our ability to renovate our properties. We have not conducted an audit or investigation of all of our properties to determine our compliance with laws and regulations to which we are subject. If one or more of our properties is not in compliance with the material provisions of the ADA or other legislation, then we may be required to incur additional costs to bring the property into compliance with the ADA or state or local laws. We cannot predict the ultimate amount of the cost of compliance with ADA or other legislation. If we incur substantial costs to comply with the ADA and any other legislation, our financial condition, results of operations and cash flow and/or ability to satisfy our debt service obligations and to make distributions to SL Green could be adversely affected.

We face potential conflicts of interest.

Members of management may have a conflict of interest over whether to enforce terms of agreements with entities which Mr. Green, directly or indirectly, has an affiliation.

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. SL Green, including us, and our tenants accounted for 14.4% of Alliance's 2015 estimated total revenue. While we believe that the contracts pursuant to which these services are provided were the result of arm's length negotiations, there can be no assurance that the terms of such agreements, or dealings between the parties during the performance of such agreements, will be as favorable to us as those which could be obtained from unaffiliated third parties providing comparable services under similar circumstances.

SL Green's failure to qualify as a REIT would be costly and would have a significant effect on the value of SL Green's securities.

We believe that SL Green has operated in a manner to qualify as a REIT for federal income tax purposes and SL Green intends to continue to so operate. Many of the REIT compliance requirements, however, are highly technical and complex. The determination that SL Green is a REIT requires an analysis of factual matters and circumstances. These matters, some of which are not totally within our or SL Green's control, can affect its qualification as a REIT. For example, to qualify as a REIT, at least 95% of SL Green's gross income must come from designated sources that are listed in the REIT tax laws. SL Green is also required to distribute to stockholders at least 90% of its REIT taxable income excluding capital gains. The fact that SL Green holds its assets through the Operating Partnership and its subsidiaries further complicates the application of the REIT requirements. Even a technical or inadvertent mistake could jeopardize SL Green's REIT status. Furthermore, Congress and the Internal Revenue Service, or the IRS, might make changes to the tax laws and regulations, and the courts might issue new rulings that make it more difficult, or impossible, for SL Green to remain qualified as a REIT.

If SL Green fails to qualify as a REIT, it would substantially reduce the funds available for distribution to its stockholders because it would not be allowed a deduction for dividends paid to its stockholders in computing its taxable income and would be subject to federal income tax at regular corporate rates and it could be subject to the federal alternative minimum tax and possibly increased state and local taxes.

Also, unless the IRS grants SL Green relief under specific statutory provisions, it would remain disqualified as a REIT for four years following the year it first failed to qualify. If SL Green failed to qualify as a REIT, it would have to pay significant income taxes and ROP would therefore have less money available for investments, to service debt obligations or make distributions to SL Green. This would likely have a significant adverse effect on the value of SL Green's securities. As a result of all these factors, if SL Green fails to qualify as a REIT, this could impair our ability to expand our business and raise capital.

SL Green would incur adverse tax consequences if RARC failed to qualify as a REIT.

SL Green has assumed that RARC has historically qualified as a REIT for United States federal income tax purposes and that SL Green would continue to be able to qualify as a REIT following the Merger. However, if RARC failed to qualify as a REIT, SL Green generally would have succeeded to significant tax liabilities including the significant tax liability that would result from a deemed sale of assets by RARC pursuant to the Merger.

Loss of our key personnel could harm our operations.

We are dependent on the efforts of Marc Holliday, the chief executive officer of SL Green and president of Wyoming Acquisition GP LLC, or WAGP, the sole general partner of ROP, and Andrew W. Mathias, the president of SL Green. These officers have employment agreements which expire in January 2019 and December 2016, respectively. A loss of the services of either of these individuals could adversely affect our operations.

Our business and operations would suffer in the event of system failures or cyber security attacks.

Despite system redundancy, the implementation of security measures and the existence of a disaster recovery plan for our internal information technology systems, our systems are vulnerable to a number of risks including energy blackouts, natural disasters, terrorism, war, telecommunication failures and cyber attacks and intrusions, such as computer viruses, malware, attachments to e-mails, intrusion and unauthorized access, including from persons inside our organization or from persons outside our organization with access to our systems. The risk of a security breach or disruption, particularly through cyber attacks and intrusions, including by computer hackers, foreign governments and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and instructions from around the world have increased. Our systems are critical to the operation of our business and any system failure, accident or security breach that causes interruptions in our operations could result in a material disruption to our business. We may also incur additional costs to remedy damages caused by such disruptions. Although we make efforts to maintain the security and integrity of our systems and have implemented various measures to manage the risk of a security breach or disruption, there can be no assurance that our security efforts and measures will be effective or that attempted security breaches or disruptions would not be successful or damaging. Any compromise of our security could also result in a violation of applicable privacy and other laws, significant legal and financial exposure, damage to our reputation, loss or misuse of the information (which may be confidential, proprietary and/or commercially sensitive in nature) and a loss of confidence in our security measures, which could harm our business.

Our property taxes could increase due to reassessment or property tax rate changes.

We are required to pay real property taxes in respect of our properties and such taxes may increase as our properties are reassessed by taxing authorities or as property tax rates change. An increase in the assessed value of our properties or our property tax rates could adversely impact our financial condition, results of operations and our ability to service debt obligations and make distributions to SL Green.

Compliance with changing or new regulations applicable to corporate governance and public disclosure may result in additional expenses, affect our operations and affect our reputation.

Changing or new laws, regulations and standards relating to corporate governance and public disclosure, including SEC regulations and the New York Stock Exchange rules, can create uncertainty for public companies. These changed or new laws, regulations and standards are subject to varying interpretations in many cases due to their lack of specificity. As a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We are committed to maintaining high standards of corporate governance and public disclosure. If our efforts to comply with new or changed laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice, our reputation may be harmed.

Our efforts to comply with evolving laws, regulations and standards have resulted in, and are likely to continue to result in, increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities. In particular, our continued efforts to comply with Section 404 of the Sarbanes-Oxley Act of 2002 and the related regulations regarding our required assessment of our internal controls over financial reporting and our external auditors' audit of that assessment have required the commitment of significant financial and managerial resources. We expect these efforts to require the continued commitment of significant resources. Further, our directors, president and treasurer could face an increased risk of personal liability in connection with the performance of their duties. As a result, we may have difficulty attracting and retaining qualified directors and executive officers, which could harm our business.

As of December 31, 2015, our portfolio also included ownership interests in 19 commercial office buildings encompassing approximately 3.3 million rentable square feet located in Brooklyn, Westchester County, Connecticut and New Jersey. We refer to these buildings as our Suburban properties. Some of these buildings also include a small amount of retail space on the lower floors, as well as basement/storage space.

As of December 31, 2015, we also owned in Manhattan, a mixed-use residential and prime retail property encompassing approximately 492,987 square feet and a land interest encompassing approximately 197,654 square feet. As of December 31, 2015, we also held debt, preferred equity, and other investments with a book value of $1.8 billion.

(3) The term "Class B" is generally used in the Manhattan office market to describe office properties that are more than 25 years old but that are in good physical condition, enjoy widespread acceptance by high-quality tenants and are situated in desirable locations in Manhattan. Class B office properties can be distinguished from Class A properties in that Class A properties are generally newer properties with higher finishes and frequently obtain the highest rental rates within their markets.

Historically SL Green has achieved consistently higher occupancy rates in its Westchester County and Connecticut portfolios in comparison to the overall Westchester County and Stamford, Connecticut, CBD markets, as shown over the last five years in the following table:

Lease Expirations

Leases in our Manhattan portfolio, as at many other Manhattan office properties, typically have an initial term of seven to fifteen years, compared to typical lease terms of five to ten years in other large U.S. office markets. For the five years ending December 31, 2020, the average annual rollover at our Manhattan operating properties is expected to be approximately 0.6 million square feet representing an average annual expiration rate of approximately 6.9% per year (assuming no tenants exercise renewal or cancellation options and there are no tenant bankruptcies or other tenant defaults).

Environmental Matters

We engaged independent environmental consulting firms to perform Phase I environmental site assessments on our portfolio, in order to assess existing environmental conditions. All of the Phase I assessments met the American Society for Testing and Materials (ASTM) Standard. Under the ASTM Standard, a Phase I environmental site assessment consists of a site visit, a historical record review, a review of regulatory agency data bases and records, and interviews with on-site personnel, with the purpose of identifying potential environmental concerns associated with real estate. These environmental site assessments did not reveal any known environmental liability that we believe will have a material adverse effect on our results of operations or financial condition.

ITEM 3.    LEGAL PROCEEDINGS

As of December 31, 2015, we were not involved in any material litigation nor, to management's knowledge, was any material litigation threatened against us or our portfolio other than routine litigation arising in the ordinary course of business or litigation that is adequately covered by insurance.

ITEM 4.    MINE SAFETY DISCLOSURES

Not Applicable.

ITEM 6.    SELECTED FINANCIAL DATA

The following table sets forth our selected financial data and should be read in conjunction with our Financial Statements and notes thereto included in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Item 8, "Financial Statements and Supplementary Data" in this Annual Report on Form 10-K.

In connection with this Annual Report on Form 10-K, we are restating our historical audited consolidated financial statements as a result of the transfer of two properties, SL Green's tenancy in common interest in a fee interest and one entity that held debt investments and financing receivables to us by SL Green. Under the Business Combinations guidance, these transfers were determined to be transfers of businesses between the indirect parent company and its wholly-owned subsidiary. As such, the assets and liabilities of the properties were transferred at their carrying values and were 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.

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF

OPERATIONS

Overview

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

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

The following discussion related to our consolidated financial statements should be read in conjunction with the financial statements appearing in Item 8 of this Annual Report on Form 10-K.

The New York City commercial real estate market continued to strengthen in 2015, and we took advantage of this strengthening market in improving occupancies and deploying capital in the borough of Manhattan to strategically position the Company for future growth.

Leasing and Operating

In 2015, SL Green's same-store Manhattan office property occupancy based on leases signed increased to 97.1% from 95.7% in the prior year. SL Green signed office leases in Manhattan encompassing approximately 2.3 million square feet, of which approximately 0.9 million square feet represented office leases that replaced previously occupied space. SL Green's mark-to-market on these approximately 0.9 million square feet of signed Manhattan office leases that replaced previously occupied space was 15.3% for 2015.

According to Cushman and Wakefield, new leasing activity in Manhattan in 2015 totaled approximately 28.2 million square feet. Of the total 2015 leasing activity in Manhattan, the Midtown submarket accounted for approximately 18.5 million square feet, or approximately 65.6%. Midtown's overall office vacancy decreased from 9.3% at December 31, 2014 to 8.5% at December 31, 2015.

Overall average asking rents in Manhattan increased from $67.70 per square foot at December 31, 2014 to $71.58 per square foot at December 31, 2015. Midtown Manhattan average asking rents increased from $75.14 per square foot at December 31, 2014 to $76.65 per square foot at December 31, 2015. The Midtown South average asking rent rose 14.7% year-over-year to $69.66 per square foot while downtown average asking rents increased 16.7% year-over-year to $59.58 per square foot.

Assets Transfer

In 2015, SL Green transferred two properties and SL Green's tenancy in common interest in a fee interest with a total value of $395.0 million to ROP. Additionally, in 2015, SL Green transferred one property that held debt investments and financing receivables with an aggregate carrying value of $1.7 billion to ROP. During 2014, SL Green transferred five properties with a total value aggregating $884.3 million to ROP. These transfers were made to further diversify ROP's portfolio. These transfers were made to further diversify ROP's portfolio. Under the business combinations guidance (Accounting Standard Codification, or ASC, 805-50), these transfers were determined to be transfers of businesses between the indirect parent company and its wholly-owned subsidiary. As such, the assets and liabilities of the properties were transferred at their carrying values and were recorded as of the beginning of the current reporting period as though the assets and liabilities had been transferred at that date. The financial statements and financial information presented for all prior periods have been retrospectively adjusted to furnish comparative information.

As of December 31, 2015, we owned the following interests in properties in the New York Metropolitan area, primarily in midtown Manhattan. Our investments in the New York Metropolitan area also include investments in Brooklyn, Westchester County, Connecticut and New Jersey, which are collectively known as the Suburban properties:

Location	Type	Number of Properties	Approximate Square Feet	Weighted Average Occupancy(1)

____________________________________________________________________

(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 December 31, 2015, we owned a building that was comprised of approximately 270,132 square feet of retail space and approximately 222,855 square feet of residential space. For the purpose of this report, we have included the building in the retail properties count and have bifurcated the square footage into the retail and residential components.

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

As of December 31, 2015, we also held debt, preferred equity and other investments with a book value of $1.8 billion.

Critical Accounting Policies

Our discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, and contingencies as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We evaluate our assumptions and estimates on an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.

Investment in Commercial Real Estate Properties

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted 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 either their carrying value or fair value less costs to sell. Except as discussed below, we do not believe that there were any indicators of impairment at any of our consolidated properties at December 31, 2015.

During the three months ended September 30, 2015, we recorded a $10.0 million charge in connection with the sale of one of our properties, which closed in the fourth quarter of 2015. This charge is included in depreciable real estate reserves in the consolidated statements of operations. Prior to the quarter ended September 30, 2015, we do not believe that there were any indicators of impairment at this property. See Note 4, "Property Dispositions."

We incur a variety of costs in the development and leasing of our properties. After determination is made to capitalize a cost, it is allocated to the specific component of a project that is benefited. Determination of when a development project is substantially complete and capitalization must cease involves a degree of judgment. The costs of land and building under development include specifically identifiable costs. The capitalized costs include, but are not limited to, pre-construction costs essential to the

23

development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. We consider a construction project as substantially completed and held available for occupancy upon the completion of tenant improvements, but no later than one year after major construction activity ceases. We cease capitalization on the portions substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portions under construction.

We recognize the assets acquired, liabilities assumed (including contingencies) and any noncontrolling interests in an acquired entity at their fair values on the acquisition date. We expense transaction costs related to the acquisition of certain assets as incurred, which are included in transaction related costs on our consolidated statements of operations. Results of operations of properties acquired are included in the consolidated statements of operations from the date of acquisition.

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

Investment in Unconsolidated Joint Ventures

We account for our investment in the unconsolidated joint venture under the equity method of accounting in cases where we exercise significant influence, but do not control the entity and are not considered to be the primary beneficiary. We consolidate those 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 we are determined to be the primary beneficiary in a VIE, these participating rights preclude us from consolidating these VIE entities. These investments are recorded initially at cost, as investments in unconsolidated joint ventures, and subsequently adjusted for equity in net income (loss) and cash contributions and distributions. Equity in net income (loss) from unconsolidated joint ventures 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. None of the joint venture debt is recourse to us. See Note 5, "Debt, Preferred Equity and Other Investments."

We assess our investments in unconsolidated joint ventures for recoverability, and if it is determined that a loss in value of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments for impairment based on the joint venture's projected discounted cash flows. We do not believe that the values of any of our equity investments were impaired at December 31, 2015.

We may originate loans for real estate acquisition, development and construction, where we expect to receive some of the residual profit from such projects. When the risk and rewards of these arrangements are essentially the same as an investor or joint venture partner, we account for these arrangements as real estate investments under the equity method of accounting for investments. Otherwise, we account for these arrangements consistent with our loan accounting for our debt and preferred equity investments.

Revenue Recognition

Rental revenue is recognized 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.

24

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 provided that we have no substantial economic involvement with the buyer.

Interest income on debt and 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 debt and 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 is 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 an adjustment to the interest income over the terms of the related investments using the effective interest method. Fees received in connection with loan commitments are also deferred until the loan is funded and are then recognized over the term of the loan as an adjustment to yield.

Debt and 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 debt or preferred equity investment is resumed when such non-accrual debt or 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 the loans individually. When a transaction meets the criteria for 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, original issue discounts, 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 statements of operations. Any fees received at the time of sale or syndication are recognized as part of investment income.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our tenants to make required payments. If the financial condition of a specific tenant were to deteriorate, resulting in an impairment of its ability to make payments, additional allowances may be required.

Reserve for Possible Credit Losses

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

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the net fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during years ended December 31, 2015, 2014 and 2013.

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

Derivative Instruments

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. Effectiveness is essential for those derivatives that we intend to qualify for hedge accounting. Some derivative instruments are associated with an anticipated transaction. In those cases, hedge effectiveness criteria also require that it be probable that the underlying transaction occurs. Instruments that meet these hedging criteria are formally designated as hedges at the inception of the derivative contract.

25

To determine the fair values of derivative instruments, we use a variety of methods and assumptions that are based on market conditions and risks existing at each balance sheet date. For the majority of financial instruments including most derivatives, long-term investments and long-term debt, standard market conventions and techniques such as discounted cash flow analysis, option-pricing models, replacement cost, and termination cost are used to determine fair value. All methods of assessing fair value result in a general approximation of value, and such value may never actually be realized.

Results of Operations

Comparison of the year ended December 31, 2015 to the year ended December 31, 2014

The following section compares the results of operations for the year ended December 31, 2015 to the year ended December 31, 2014 for the 43 properties owned by ROP. The Company adopted ASU 2014-08 effective January 1, 2015. As a result, the Company classified 140 Grand Street as held for sale as of September 30, 2015 and included the results of operations in continuing operations for all periods presented. Any assets sold or held for sale prior to January 1, 2015 were excluded from income from continuing operations and from the following discussion.

Rental, Escalation and Reimbursement Revenues

Rental revenue increased primarily as a result of an increase in occupancy ($26.6 million), the acquisitions of three properties in 2014 ($12.7 million), one property that was placed in service in July 2015 ($6.6 million) and one property which we acquired in July 2015 ($3.7 million), partially offset by the sale of an 80% interest in 131-137 Spring Street in August 2015 which resulted in deconsolidation of the property ($4.9 million).

Escalation and reimbursement revenue increased primarily as a result of higher real estate tax recoveries ($4.3 million), partially offset by lower operating expense escalations and electric reimbursements ($1.3 million).

Occupancy in our Manhattan office operating properties was 94.9% at December 31, 2015 compared to 91.7% at December 31, 2014. Occupancy in our Suburban office operating properties was 80.0% at December 31, 2015 compared to 79.8% at December 31, 2014. At December 31, 2015, approximately 6.3% and 10.5% of the space leased at our Manhattan and Suburban operating properties, respectively, is expected to expire during 2016. Based on our estimates, the current market asking rents on

26

these expected 2016 lease expirations at our consolidated Manhattan operating properties are 9.6% higher than the existing in-place fully escalated rents while the current market asking rents on all our consolidated Manhattan operating properties are 11.0% higher than the existing in-place fully escalated rents that are scheduled to expire in all future years. Based on our estimates, the current market asking rents on these expected 2016 lease expirations at our consolidated Suburban operating properties are 8.6% higher than the existing in-place fully escalated rents while the current market asking rents on all our consolidated Suburban operating properties are 7.8% higher than the existing in-place fully escalated rents that are scheduled to expire in all future years.

Investment Income

Investment income increased primarily as a result of higher average investment balances for the year ended December 31, 2015. For the twelve months ended December 31, 2015, the weighted average debt and preferred equity investment balance outstanding and weighted average yield were $1.7 billion and 10.3%, respectively, compared to $1.4 billion and 10.5%, respectively, for the same period in 2014. In addition, we recognized additional income as a result of the early repayment of certain mortgage and mezzanine positions ($2.5 million) and the sale of a junior mortgage position ($1.2 million). This increase was partially offset by additional income recognized in 2014 on a mezzanine investment for which the underlying property was sold in June 2014 ($10.1 million) and a financing receivable on which we began accruing interest following the completion of the development of the underlying property ($5.3 million). As of December 31, 2015, the debt and preferred equity investments had a weighted average term to maturity of 1.7 years as compared to a weighted average term to maturity of 2.0 years as of December 31, 2014.

Other Income

Other income increased primarily as a result of alease termination fee received at 919 Third Avenue in 2015 ($14.5 million) and a non-recurring fee related to the settlement of a previous investment ($6.5 million).

Property Operating Expenses

Property operating expenses increased primarily as a result of higher real estate taxes resulting from higher assessed values and tax rates ($10.3 million), professional fees ($2.4 million), repairs and maintenance ($2.0 million) and payroll ($1.1 million).

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

Interest expense and amortization of financing costs, net of interest income, decreased primarily as a result of the repayment of mortgages at 625 Madison Avenue ($8.4 million) and 125 Park Avenue ($4.3 million) during the fourth quarter of 2014 and 711 Third ($4.8 million) in the first quarter of 2015, redemption of a preferred equity investments which secured a loan during the fourth quarter of 2014 ($3.8 million) and the repayment of 5.875% senior notes in August 2014 ($2.8 million), partially offset by increased borrowings on the 2012 credit facility ($10.9 million) and one property that was placed in service ($2.6 million).

Depreciation and amortization

Depreciation and amortization increased primarily as a result of the properties acquired in 2014 ($5.7 million) and one property that was placed into service in July 2015 ($1.7 million). These increases were partially offset by the sale of an 80% interest in 131-137 Spring Street in August 2015 which resulted in deconsolidation of the property ($3.0 million).

Equity in net income from unconsolidated joint ventures

Equity in net income from unconsolidated joint venture increased primarily as a result of the net loss recognized in 2013 from a portfolio of office properties in Southern California, or the "West Coast portfolio," which were sold in March 2014 ($2.4 million) and the origination of another investment accounted for under the equity method accounting as a result of meeting the criteria of a real estate investment under the guidance of Acquisition, Development and Construction arrangement in 2014 ($1.8 million).

Equity in Net Gain on Sale of Unconsolidated Joint Venture

During the year ended December 31, 2014, we recorded gains on the sale of our West Coast portfolio ($85.6 million).

Gain on Sale of Real Estate

During the year ended December 31, 2015, we recognized a gain on sale associated with the sale of an 80% interest in 131-137 Spring Street ($101.1 million). This gain was offset by a charge in connection with the sale of 140 Grand Street.

Depreciable Real Estate Reserves

During the year ended December 31, 2015, we recorded a $10.0 million charge in connection with the sale of 140 Grand Street.

Loss on Early Extinguishment of Debt

Loss on early extinguishment of debt during the year ended December 31, 2014 was a result of the early repayment of debt at 625 Madison Avenue ($6.9 million) and 16 Court Street, Brooklyn ($0.5 million).

The following section compares the results of operations for the year ended December 31, 2014 to the year ended December 31, 2013 for the 42 properties owned by ROP. Acquisition properties represent properties acquired in 2014 or 2013 and properties transferred to us by SL Green following its acquisition. Any assets sold or held for sale are excluded from income from continuing operations.

Rental, Escalation and Reimbursement Revenues

Rental revenue increased primarily as a result of the acquisitions of 315 West 33rd Street in November 2013 ($22.9 million) and 16 Court Street, Brooklyn ($3.7 million), increase in occupancy at 1185 Avenue of the Americas ($7.8 million), and a one-time write-off of value for above-market leases associated with a former tenant ($6.8 million) in 2013.

Escalation and reimbursement revenue increased primarily as a result of the acquisition of 315 West 33rd Street in November 2013 ($4.0 million) and higher real estate tax recoveries from non-acquisition properties ($2.6 million).

Occupancy in our Manhattan office properties was 91.7% at December 31, 2014 compared to 92.9% at December 31, 2013. Occupancy in our Suburban office properties was 79.8% at December 31, 2014 compared to 78.3% at December 31, 2013. At December 31, 2014, excluding the impact of the properties transferred in 2015, approximately 1.9% and 6.8% of the space leased at our Manhattan and Suburban office properties, respectively, is expected to expire during 2015. Based on our estimates, the current market asking rents on all our Manhattan operating properties for leases that are expected to expire during 2015 would be approximately 42.3% higher than the existing in-place fully escalated rents while the current market asking rents on all our Manhattan operating properties for leases that are scheduled to expire in future years would be approximately 10.4% higher than the existing in-place fully escalated rents. Based on our estimates, the current market asking rents on all our Suburban operating properties for leases that are expected to expire during 2015 would be approximately 2.5% lower than the existing in-place fully escalated rents while the current market asking rents on all our Suburban operating properties for leases that are scheduled to expire in future years would be approximately 3.2% higher than the existing in-place fully escalated rents.

Investment Income

Investment income decreased primarily as a result of a lower weighted average yield on the debt and preferred equity portfolio, a gain on sale of 50% of our interest in one of our debt investments in 2013 ($12.9 million), additional income from the repayment of one of our debt investments in 2013 ($6.4 million), a one-time recognition of unrecognized interest ($6.1 million) related to one of our preferred equity investments in 2013, and theredemption of one of our preferred equity investments in April 2014 ($1.2 million), partially offset bya higher investment balance in 2014, additional income recognized on a mezzanine investment when the underlying property was sold in June 2014 ($10.1 million) and financing receivable on which we began accruing interest following the completion of the development of the underlying property ($5.3 million).The weighted average investment balance outstanding and weighted average yield were $1.4 billion and 10.5%, respectively, for the year ended December 31, 2014 as compared to $1.3 billion and 11.2%, respectively, for the year ended December 31, 2013.As of December 31, 2014, our debt and preferred equity investments had a weighted average term to maturity of 2.0 years.

Other Income

Other income decreased primarily as a result of lower lease buy-out income ($0.9 million).

Property Operating Expenses

Property operating expenses increased primarily as a result of the acquisition of 315 West 33rd Street ($13.0 million) and 16 Court Street, Brooklyn ($1.5 million) and higher real estate taxes resulting from higher assessed values and tax rates from non-acquisition properties ($7.2 million).

Transaction Related Costs

Transaction related costs increased primarily as a result of higher investment activity during the year ended December 31, 2014.

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

Interest expense, net of interest income, decreased primarily as a result of the capitalization of interest relating to properties under development or redevelopment ($3.8 million), decreased average borrowings under the master repurchase agreement facility ($1.8 million) and the repayment of 5.875% senior notes in August 2014 ($1.7 million) and debt at 125 Park Avenue ($1.6 million) and 16 Court Street, Brooklyn ($1.2 million) in 2014. The decrease in interest expense was partially offset by higher interest as a result of increased borrowing on the 2012 credit facility ($6.1 million).

Depreciation and Amortization Expense

Depreciation and amortization increased primarily as a result of the acquisition of 315 West 33rd Street ($14.3 million) and 16 Court Street, Brooklyn ($1.6 million), partially offset by a one-time write-off of tenant improvements and value for in-place leases associated with a former tenant ($4.7 million) in 2013.

Equity in Net Income from Unconsolidated Joint Venture

Equity in net income from unconsolidated joint venture increased primarily as a result of net loss recognized in 2013 from the portfolio of offices properties primarily in Southern California, or the "West Coast Office Portfolio" ($18.7 million) which interest was sold in March 2014 and a debt and preferred equity investment that was originated in the first quarter of 2014 ($6.9 million), which has been accounted for as an equity investment as a result of meeting the criteria of a real estate investment under the Acquisition, Development and Construction arrangement. These increases were partially offset by early redemption of the underlying preferred equity investment of our equity investment in 2013 ($3.9 million).

Equity in Net Gain on Sale of Unconsolidated Joint Venture

During the year ended December 31, 2014, we recorded gains on the sale of our West Coast portfolio ($85.6 million). During the year ended December 31, 2013, we recognized gains on the sale of three properties in the West Coast portfolio ($2.1 million)

Loss on Early Extinguishment of Debt

Loss on early extinguishment of debt during the year ended December 31, 2014 was a result of the early repayment of debt at 625 Madison Avenue ($6.9 million) and 16 Court Street, Brooklyn ($0.5 million).

Discontinued Operations

Discontinued operations for the year ended December 31, 2014 includes the gain recognized on the sale of 673 First Avenue ($117.6 million) and the results of its operations. Discontinued operations for the year ended December, 2013 includes the gain recognized on the sale of 333 West 34th Street ($13.8 million). Prior year's results of operations of these sold properties were included in the net income from discontinued operations to conform to the current presentation.

Liquidity and Capital Resources

On January 25, 2007, we were acquired by SL Green. See Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources" in SL Green and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2015 for a complete discussion of additional sources of liquidity available to us due to our indirect ownership by SL Green.

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

(1) cash flow from operations;

(2) cash on hand;

(3) borrowings under the 2012 credit facility;

(4) other forms of secured or unsecured financing;

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

(6) proceeds from debt offerings by us.

Cash flow from operations is primarily dependent upon the occupancy level of our portfolio, the net effective rental rates achieved on our leases, the collectability of rent, operating escalations and recoveries from our tenants and the level of operating and other costs. Additionally, we believe that our preferred equity investment program will continue to serve as a source of operating cash flow.

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

Cash Flows

The following summary discussion of our cash flows is based on our consolidated statements of cash flows in "Item 8. Financial Statements and Supplementary Data" and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below.

Cash and cash equivalents were $50.0 million and $34.7 million at December 31, 2015 and 2014, respectively, representing an increase of $15.3 million. The increase was a result of the following changes in cash flows (in thousands):

	Year ended December 31,
	2015			2014			Change
				(as adjusted)
Net cash provided by operating activities	$	365,485		$	283,395		$	82,090
Net cash used in investing activities	$	(225,874	)	$	(498,587	)	$	272,713
Net cash (used in) provided by financing activities	$	(124,276	)	$	200,839		$	(325,115	)

Our principal source of operating cash flow is related to the leasing and operating of the properties in our portfolio. Our properties provide a relatively consistent stream of cash flow that provides us with resources to pay operating expenses, debt service and make distributions to SL Green. At December 31, 2015, our Manhattan and Suburban consolidated office portfolio were 94.9% and 80.0% occupied, respectively. Our debt and preferred investments also provide a steady stream of operating cash flow to us.

Cash is used in investing activities to fund acquisitions, development or redevelopment projects and recurring and nonrecurring capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing and property management skills and invest in existing buildings that meet our investment criteria. During the year ended December 31, 2015, when compared to the year ended December 31, 2014, we used cash primarily for the following investing activities (in thousands):

30

Acquisitions of real estate	$	407,902
Capital expenditures and capitalized interest	12,907
Net proceeds from sale of real estate/joint venture interest	1,024
Joint venture investments	58,412
Distributions from unconsolidated joint ventures	28,459
Debt, preferred and other investments	(235,927		)
Restricted cash—capital improvements	(64		)
Decrease in net cash used in investing activities	$	272,713

Funds spent on capital expenditures, which comprise building and tenant improvements, decreased from $102.9 million for the year ended December 31, 2014 compared to $90.0 million for the year ended December 31, 2015. The decrease in capital expenditures relate primarily to lower costs incurred in connection with the redevelopment of a property and the build-out of space for tenants.

We generally fund our investment activity through property-level financing, our 2012 credit facility, senior unsecured notes and sale of real estate. During the year ended December 31, 2015, when compared to the year ended December 31, 2014, we used cash for the following financing activities (in thousands):

Repayments under our debt obligations	$	(31,471	)
Proceeds from debt obligations	745,802
Contributions from common unitholder and noncontrolling interests	(482,479		)
Distributions to common and preferred unitholder and noncontrolling interests	(576,137		)
Obligation related to mortgage loan participation	25,000
Deferred loan costs	(5,830		)
Increase in cash used in financing activities	$	(325,115	)

2012 Credit Facility

In July 2015, we entered into the third amendment to the credit facility that was originally entered into by the Company in November 2012, referred to as the 2012 credit facility, which increased our unsecured corporate facility by $500.0 million. The revolving credit facility was increased by $400.0 million to $1.6 billion and the term loan portion of the facility was increased by $100.0 million to $933.0 million.

In January 2015, we amended the 2012 credit facility by entering into a second amended and restated credit agreement, which decreased the interest-rate margin and facility fee applicable to the revolving credit facility by 20 basis points and five basis points, respectively, and extended the maturity date of the revolving credit facility to March 29, 2019 with an as-of-right extension through March 29, 2020.

In November 2014, we increased the term loan portion of the facility by $50.0 million to $833.0 million.

In March 2014, we entered into an amendment to the 2012 credit facility, which among other things, increased the term loan portion of the facility by $383.0 million to $783.0 million, decreased the interest-rate margin applicable to the term loan portion of the 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.

As of December 31, 2015, the 2012 credit facility, as amended, consisted of a $1.6 billion revolving credit facility, or the revolving credit facility, and a $933.0 million term loan, or the term loan facility. We also have an option, subject to customary conditions, to increase the capacity under the revolving credit facility to $3.0 billion at any time prior to the maturity date for the revolving credit facility without the consent of existing lenders, by obtaining additional commitments from our existing lenders and other financial institutions.

As of December 31, 2015, the 2012 credit facility bore interest at a spread over LIBOR ranging from (i) 87.5 basis points to 155 basis points for loans under the revolving credit facility and (ii) 95 basis points to 190 basis points for loans under the term loan facility, in each case based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. At December 31,

31

2015, the applicable spread was 125 basis points for revolving credit facility and 140 basis points for the term loan facility. At December 31, 2015, the effective interest rate was 1.45% for the revolving credit facility and 1.67% for the term loan facility. We are required to pay quarterly in arrears a 12.5 basis points to 30 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. As of December 31, 2015, the facility fee was 25 basis points. As of December 31, 2015, we had $73.1 million of outstanding letters of credit, $994.0 million drawn under the revolving credit facility and $933.0 million outstanding under the term loan facility, with total undrawn capacity of $532.9 million under the 2012 credit facility.

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

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

Master Repurchase Agreement

The Master Repurchase Agreement, as amended in December 2013, or MRA, provides us with the ability to sell certain debt investments with a simultaneous agreement to repurchase the same at a certain date or on demand. This MRA has a maximum facility capacity of $300.0 million and bears interest ranging from 250 and 325 basis points over 30-day LIBOR depending on the pledged collateral. In September 2015 we entered into an amendment to the MRA to extend the maturity to June 29, 2016. Further, as of December 6, 2015 we are now required to pay monthly in arrears a 25 basis point fee on the excess of $150.0 million over the average daily balance during the period if the average daily balance is less than $150.0 million. We seek to mitigate risks associated with our repurchase agreement by managing the credit quality of our assets, early repayments, interest rate volatility, liquidity, and market value. The margin call provisions under our repurchase facility permit valuation adjustments based on capital markets activity, and are not limited to collateral-specific credit marks. To monitor credit risk associated with our debt investments, our asset management team regularly reviews our investment portfolio and is in contact with our borrowers in order to monitor the collateral and enforce our rights as necessary. The risk associated with potential margin calls is further mitigated by our ability to recollateralize the facility with additional assets from our portfolio of debt investments, our ability to satisfy margin calls with cash or cash equivalents and access to additional liquidity through the 2012 Credit Facility.

Senior Unsecured Notes

The following table sets forth our senior unsecured notes and other related disclosures as of December 31, 2015 and 2014, respectively, by scheduled maturity date (dollars in thousands):

(1) Interest on the senior unsecured notes is payable semi-annually with principal and unpaid interest due on the scheduled maturity dates.

(2) The notes will be repaid at maturity.

(3) Issued by SL Green, the Operating Partnership and ROP, as co-obligors.

(4) In April 2015, we redeemed the remaining outstanding debentures.

ROP also provides a guaranty of the Operating Partnership's obligations under its 3.00% Exchangeable Senior Notes due 2017.

Restrictive Covenants

The terms of the 2012 credit facility, as amended, and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, SL Green's ability to pay dividends, make certain types of investments, incur additional indebtedness, incur liens and enter into negative pledge agreements and dispose of assets, and which require compliance with financial ratios relating to the maximum ratio of total indebtedness to total asset value, a minimum ratio of EBITDA to fixed charges, a maximum ratio of secured indebtedness to total asset value and a maximum ratio of unsecured indebtedness to unencumbered asset value. The dividend restriction referred to above provides that SL Green will not during any time when a default is continuing, make distributions with respect to SL Green's common stock or other equity interests, except to enable SL Green to continue to qualify as a REIT for Federal income tax purposes. As of December 31, 2015 and 2014, we were in compliance with all such covenants.

Interest Rate Risk

We are exposed to changes in interest rates primarily from our variable rate debt. Our exposure to interest rate changes are managed through either the use of interest rate derivative instruments and/or through our variable rate preferred equity investments. A hypothetical 100 basis point increase in interest rates along the entire interest rate curve for 2015 would increase our annual interest cost, net of interest income from variable rate preferred equity investments, by approximately $10.0 million.

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

We have $1.6 billion of long term debt that bears interest at fixed rates, and therefore the fair value of these instruments is affected by changes in the market interest rates. Our variable rate debt as of December 31, 2015 bore interest based on a spread of LIBOR plus 125 basis points to LIBOR plus 315 basis points.

Contractual Obligations

The combined aggregate principal maturities of mortgage note and other loans payable, the 2012 credit facility and senior unsecured notes, including extension options, put options, estimated interest expense, and our obligations under our and ground leases, as of December 31, 2015 are as follows (in thousands):

Off-Balance Sheet Arrangements

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

Capital Expenditures

We estimate that for the year ending December 31, 2016, we expect to incur $105.0 million of recurring capital expenditures and $27.9 million of development or redevelopment expenditures, net of loan reserves, (including tenant improvements and leasing commissions) on existing consolidated properties. Future property acquisitions may require substantial capital investments for refurbishment and leasing costs. We expect to fund these capital expenditures with operating cash flow, existing liquidity, or incremental borrowings. We expect our capital needs over the next twelve months and thereafter will be met through a combination of cash on hand, net cash provided by operations, borrowings, potential asset sales or additional debt issuances.

Related Party Transactions

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. Income earned from profit participation, which is included in other income on the consolidated statements of operations, was $3.3 million, $3.3 million and $3.0 million for the years ended December 31, 2015, 2014 and 2013 respectively. We also recorded expenses of $9.9 million, $9.1 million and $9.9 million for the years ended December 31, 2015, 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. Such amount was approximately $10.4 million, $9.8 million and $9.1 million for the years ended December 31, 2015, 2014 and 2013, respectively.

Insurance

ROP is insured through a program administered by SL Green. SL Green maintains “all-risk” property and rental value coverage (including coverage regarding the perils of flood, earthquake and terrorism) within three property insurance portfolios and liability insurance. This includes ROP assets. The first property portfolio maintains a blanket limit of $950.0 million per occurrence, including terrorism, for the majority of the New York City properties in our portfolio and expires December 31, 2017. The second portfolio maintains a limit of $1.5 billion per occurrence, including terrorism, for several New York City properties and the majority of the Suburban properties and expires December 31, 2017. Each of these policies includes $100.0 million of flood coverage, with a lower sublimit for locations in high hazard flood zones. A third blanket property policy covers most of SL Green's residential assets and maintains a limit of $386.0 million per occurrence, including terrorism, for our residential properties and expires January 31, 2018. SL Green maintains two liability policies which cover all our properties and provide limits of $201.0 million per occurrence and in the aggregate per location. The liability policies expire on October 31, 2016 and January 31, 2017 and cover SL Green's commercial and residential assets, respectively. Additional coverage may be purchased on a stand-alone basis for certain assets.

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

The Terrorism Risk Insurance Act, or TRIA, which was enacted in November 2002, was renewed December 31, 2005 and again on December 31, 2007. Congress extended TRIA, now called TRIPRA (Terrorism Risk Insurance Program Reauthorization and Extension Act of 2007) until December 31, 2014. TRIPRA was not renewed by Congress and expired on December 31, 2014. However, on January 12, 2015, TRIPRA was reauthorized until December 31, 2020 (Terrorism Insurance Program Reauthorization and Extension Act of 2015).The law extends the federal Terrorism Insurance Program that requires insurance companies to offer terrorism coverage and provides for compensation for insured losses resulting from acts of certified terrorism, subject to the current program trigger of $100.0 million, which will increase by $20 million per annum, commencing December 31, 2015. Our debt instruments, consisting of mortgage loans secured by our properties (which are generally non-recourse to us), mezzanine loans, ground leases, our 2012 credit facility, senior unsecured notes and other corporate obligations, contain customary covenants requiring us to maintain insurance. Although we believe that we currently maintain sufficient insurance coverage to satisfy these obligations, there is no assurance that in the future we will be able to procure coverage at a reasonable cost. In such instances, there can be no assurance that the lenders or ground lessors under these instruments will not take the position that a total or partial exclusion from “all-risk” insurance coverage for losses due to terrorist acts is a breach of these debt and ground lease instruments allowing the lenders or ground lessors to declare an event of default and accelerate repayment of debt or recapture of ground lease positions. In addition, if lenders prevail in asserting that we are required to maintain full coverage for these risks, it could result in substantially higher insurance premiums.

We monitor all properties that are subject to triple net leases to ensure that tenants are providing adequate coverage.  Certain joint ventures may be covered under policies separate from our policies, at coverage limits which we deem to be adequate.  We

34

continually monitor these policies.  Although we consider our insurance coverage to be appropriate, in the event of a major catastrophe, we may not have sufficient coverage to replace certain properties.

We obtained insurance coverage through an insurance program administered by SL Green. In connection with this program, we incurred insurance expense of approximately $6.6 million, $6.4 million and $6.2 million for the years ended December 31, 2015, 2014 and 2013 respectively.

Related Party Receivable from SL Green

On July 22, 2015, our parent company issued a promissory note to us in the amount of $90.0 million, which bears interest at an annual rate of 6.0%, compounded quarterly, and matures on July 22, 2017.

Inflation

Substantially all of our office leases provide for separate real estate tax and operating expense escalations as well as operating expense recoveries based on increases in the Consumer Price Index or other measures such as porters' wage. In addition, many of the leases provide for fixed base rent increases. We believe that inflationary increases will be at least partially offset by the contractual rent increases and expense escalations described above.

Accounting Standards Updates

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

Forward-Looking Information

This report includes certain statements that may be deemed to be "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995 and are intended to be covered by the safe harbor provisions thereof. All statements, other than statements of historical facts, included in this report that address activities, events or developments that we expect, believe or anticipate will or may occur in the future, including such matters as future capital expenditures, dividends and acquisitions (including the amount and nature thereof), development trends of the real estate industry and the Manhattan, Brooklyn, Westchester County, Connecticut, Long Island and New Jersey office markets, business strategies, expansion and growth of our operations and other similar matters, are forward-looking statements. These forward-looking statements are based on certain assumptions and analyses made by us in light of our experience and our perception of historical trends, current conditions, expected future developments and other factors we believe are appropriate.

Forward-looking statements are not guarantees of future performance and actual results or developments may differ materially, and we caution you not to place undue reliance on such statements. Forward-looking statements are generally identifiable by the use of the words "may," "will," "should," "expect," "anticipate," "estimate," "believe," "intend," "project," "continue," or the negative of these words, or other similar words or terms.

Forward-looking statements contained in this report are subject to a number of risks and uncertainties that may cause our actual results, performance or achievements to be materially different from future results, performance or achievements expressed or implied by forward-looking statements made by us. These risks and uncertainties include:

• the effect of general economic, business and financial conditions, and their effect on the New York City real estate market in particular;

• dependence upon certain geographic markets;

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

• risks relating to debt and preferred equity investments;

• availability and creditworthiness of prospective tenants and borrowers;

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

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

• availability of capital (debt and equity);

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

• the Company's ability to comply with financial covenants in our debt instruments;

• SL Green's ability to maintain its status as a REIT;

• risks of investing through joint venture structures, including the fulfillment by our partners of their financial obligations;

• the threat of terrorist attacks;

35

• our ability to obtain adequate insurance coverage at a reasonable cost and the potential for losses in excess of our insurance coverage, including as a result of environmental contamination; and,

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

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

The risks included here are not exhaustive. Other sections of this report may include additional factors that could adversely affect ROP's business and financial performance. In addition, sections of SL Green and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2015 contain additional factors that could adversely affect our business and financial performance. Moreover, ROP operates in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on ROP's business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

Report of Independent Registered Public Accounting Firm

The Partners of Reckson Operating Partnership, L.P.

We have audited the accompanying consolidated balance sheets of Reckson Operating Partnership, L.P. (the "Company") as of December 31, 2015 and 2014, and the related consolidated statements of operations, comprehensive income, capital and cash flows for each of the three years in the period ended December 31, 2015. Our audits also included the financial statement schedules listed in the Index at Item 15(a)(2). These financial statements and schedules are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedules based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Reckson Operating Partnership, L.P. at December 31, 2015 and 2014, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedules, when considered in relation to the basic financial statements taken as a whole, present fairly in all material respects the information set forth therein.

As discussed in Note 1, the consolidated financial statements have been retrospectively adjusted to reflect the 2015 transfers of two properties, a tenancy in common interest in a fee interest and one entity that held debt investments and financing receivables to the Company from the Company's parent, SL Green Realty Corp.

Reckson Operating Partnership, L.P.

Notes to Consolidated Financial Statements

December 31, 2015

1. Organization and Basis of Presentation

Reckson Operating Partnership, L.P., or ROP, commenced operations on June 2, 1995. The sole general partner of ROP is Wyoming Acquisition GP LLC., or WAGP, a wholly-owned subsidiary of SL Green Operating Partnership, L.P., or the Operating Partnership. The sole limited partner of ROP is the Operating Partnership. The Operating Partnership is 96.39% owned by SL Green Realty Corp., or SL Green, as of December 31, 2015. SL Green is a self-administered and self-managed real estate investment trust, and is the sole managing general partner of the Operating Partnership. Unless the context requires otherwise, all references to "we," "our," "us" and the "Company" means ROP and all entities owned or controlled by ROP.

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

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.

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 2015, SL Green transferred two properties and SL Green's tenancy in common interest in a fee interest with a total value of $395.0 million to ROP. Additionally, in 2015, SL Green transferred one entity that held debt investments and financing receivables with an aggregate carrying value of $1.7 billion to ROP. During 2014, SL Green transferred five properties with a total value aggregating $884.3 million to ROP. These transfers were made to further diversify ROP's portfolio. Under the business combinations guidance (Accounting Standard Codification, or ASC, 805-50), these transfers were determined to be transfers of businesses between the indirect parent company and its wholly-owned subsidiary. As such, the assets and liabilities of the properties were transferred at their carrying values and were recorded as of the beginning of the current reporting period as though the assets and liabilities had been transferred at that date. The financial statements and financial information presented for all prior periods have been retrospectively adjusted to furnish comparative information.

As of December 31, 2015, we owned the following interests in properties in the New York Metropolitan area, primarily in midtown Manhattan. Our investments in the New York Metropolitan area also include investments in Brooklyn, Westchester County, Connecticut and New Jersey, which are collectively known as the Suburban properties:

Location	Type	Number of Properties	Approximate Square Feet (unaudited)	Weighted Average Occupancy(1) (unaudited)
Commercial:
Manhattan	Office	16	8,463,245	94.9	%
	Retail(2)(3)	5	352,892	97.6	%
	Fee Interest	2	197,654	100.0	%
		23	9,013,791	95.1	%
Suburban	Office	19	3,287,800	80.0	%
	Retail	1	52,000	100.0	%
		20	3,339,800	80.3	%
Total commercial properties		43	12,353,591	91.1	%
Residential:
Manhattan	Residential(2)	—	222,855	89.5	%
Total portfolio		43	12,576,446	91.1	%

____________________________________________________________________

(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 December 31, 2015, we owned a building that was comprised of approximately 270,132 square feet (unaudited) of retail space and approximately 222,855 square feet (unaudited) of residential space. For the purpose of this report, we have included the building in the retail properties count and have bifurcated the square footage into the retail and residential components.

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

As of December 31, 2015, we also held debt, preferred equity and other investments with a book value of $1.8 billion.

2. Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include our accounts and those of our subsidiaries, which are wholly-owned or controlled by us. Entities which we do not control through our voting interest and entities which are variable interest entities, but where we are not the primary beneficiary, are accounted for under the equity method or as preferred equity investments. See Note 5, "Debt, 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 the primary beneficiary. The primary beneficiary is the entity that has (i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE.

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 is modified to present earnings and other comprehensive income attributed to controlling and noncontrolling interests.

We assess the accounting treatment for each joint venture and debt 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 VIEs, 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, 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 the joint venture. Our joint venture agreements typically contain certain protective rights such as requiring 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

Real estate properties are presented at cost less accumulated depreciation and amortization. Costs directly related to the development or redevelopment of properties are capitalized. Ordinary repairs and maintenance are expensed as incurred; major replacements and betterments, which improve or extend the life of the asset, are capitalized and depreciated over their estimated useful lives.

A property to be disposed of is reported at the lower of its carrying value or its estimated fair value, less its cost to sell. Once an asset is held for sale, depreciation expense is no longer recorded. The Company adopted ASU 2014-08 effective January 1, 2015. As a result, the Company classified 140 Grand Street in White Plains, New York as held for sale as of September 30, 2015, and 131-137 Spring Street as of June 30, 2015 and included the results of operations in continuing operations for all periods presented. Discontinued operations included the results of operations of real estate assets sold or held for sale prior to January 1, 2015. This included 673 First Avenue, which was sold during 2014. See Note 4, "Property Dispositions."

Properties are depreciated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives are as follows:

Category	Term
Building (fee ownership)	40 years
Building improvements	shorter of remaining life of the building or useful life
Building (leasehold interest)	lesser of 40 years or remaining term of the lease
Property under capital lease	remaining lease term
Furniture and fixtures	four to seven years
Tenant improvements	shorter of remaining term of the lease or useful life

Reckson Operation Partnership, L.P.

Notes to Consolidated Financial Statements (cont.)

December 31, 2015

Depreciation expense (including amortization of the capital lease asset) amounted to $187.2 million, $184.3 million and $170.0 million for the years ended December 31, 2015, 2014 and 2013, respectively.

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted 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 either their carrying value or fair value less costs to sell. During the three months ended September 30, 2015, we recorded a $10.0 million charge in connection with the expected sale of one of our properties, which closed in the fourth quarter of 2015. This charge is included in depreciable real estate reserves in the consolidated statements of operations. Prior to the quarter ended September 30, 2015, we do not believe that there were any indicators of impairment at this property. See Note 4, "Property Dispositions." We do not believe that there were any indicators of impairment at any of our consolidated properties at December 31, 2015.

We incur a variety of costs in the development and leasing of our properties. After determination is made to capitalize a cost, it is allocated to the specific component of a project that is benefited. Determination of when a development project is substantially complete and capitalization must cease involves a degree of judgment. The costs of land and building under development include specifically identifiable costs. The capitalized costs include, but are not limited to, pre-construction costs essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. We consider a construction project as substantially completed and held available for occupancy upon the completion of tenant improvements, but no later than one year after major construction activity ceases. We cease capitalization on the portions substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portions under construction.

We recognize the assets acquired, liabilities assumed (including contingencies) and any noncontrolling interests in an acquired entity at their fair values on the acquisition date. We expense transaction costs related to the acquisition of certain assets as incurred, which are included in transaction related costs on our consolidated statements of operations. Results of operations of properties acquired are included in the consolidated statements of operations from the date of acquisition.

We allocate the purchase price of real estate to land and building (inclusive of tenant improvements) and, if determined to be material, intangibles, such as the value of above- and below-market leases and origination costs associated with the in-place leases. We depreciate the amount allocated to building (inclusive of tenant improvements) over their estimated useful lives, which generally range from three to 40 years. We amortize the amount allocated to the above- and below-market leases over the remaining term of the associated lease, which generally range from one to 14 years, and record it as either an increase (in the case of below-market leases) or a decrease (in the case of above-market leases) to rental income. We amortize the amount allocated to the values associated with in-place leases over the expected term of the associated lease, which generally ranges from one to 14 years. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off. The tenant improvements and origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). We assess fair value of the leases based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and market/economic conditions that may affect the property. To the extent acquired leases contain fixed rate renewal options that are below-market and determined to be material, we amortize such below-market lease value into rental income over the renewal period. As of December 31, 2015, the weighted average amortization period for above-market leases, below-market leases, and in-place lease costs is 4.4 years, 13.3 years, and 11.9 years, respectively.

We recognized $24.9 million, $21.0 million, and $19.0 million of rental revenue for the years ended December 31, 2015, 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. The increase in rental revenue for the year ended December 31, 2013 is net of $6.8 million resulting from the write-off of balances associated with a former tenant. Excluding this non-recurring charge, we recognized an increase of $25.8 million in rental revenue for the year ended December 31, 2013 for the amortization of aggregate below-market leases in excess of above-market leases and reductions in lease origination costs. In March 2014, we recognized income of $0.3 million for the amortization of the remaining value of below-market rate mortgage at 16 Court Street, Brooklyn, as a result of early repayment of debt. Excluding this one-time income, we recognized as a reduction to interest expense the amortization of the above-market rate mortgages assumed of $2.1 million for the

year ended December 31, 2014. We recognized as an increase (a reduction) to interest expense the amortization of the above-market rate mortgages assumed of $0.4 million and $(2.5) million for the years ended December 31, 2015 and 2013, 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 December 31, 2015 and 2014 (in thousands):

Investment in Unconsolidated Joint Ventures

We account for our investment in the unconsolidated joint venture under the equity method of accounting in cases where we exercise significant influence, but do not control the entity and are not considered to be the primary beneficiary. We consolidate those 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 we are determined to be the primary beneficiary in a VIE, these participating rights preclude us from consolidating these VIE entities. These investments are recorded initially at cost, as investments in unconsolidated joint ventures, and subsequently adjusted for equity in net income (loss) and cash contributions and distributions. Equity in net income (loss) from unconsolidated joint ventures 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. None of the joint venture debt is recourse to us. See Note 5, "Debt, Preferred Equity and Other Investments."

We assess our investments in unconsolidated joint ventures for recoverability, and if it is determined that a loss in value of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments for

impairment based on the joint venture's projected discounted cash flows. We do not believe that the values of any of our equity investments were impaired at December 31, 2015.

We may originate loans for real estate acquisition, development and construction, where we expect to receive some of the residual profit from such projects. When the risk and rewards of these arrangements are essentially the same as an investor or joint venture partner, we account for these arrangements as real estate investments under the equity method of accounting for investments. Otherwise, we account for these arrangements consistent with our loan accounting for our debt and preferred equity investments.

Cash and Cash Equivalents

We consider all highly liquid investments with maturity of three months or less when purchased to be cash equivalents.

Restricted Cash

Restricted cash primarily consists of security deposits held on behalf of our tenants, interest reserves, as well as capital improvement and real estate tax escrows required under certain loan agreements.

Deferred Lease Costs

Deferred lease costs consist of fees and direct costs incurred to initiate and renew operating leases and are amortized on a straight-line basis over the related lease term.

Deferred Financing Costs

Deferred financing costs represent commitment fees, legal, title and other third party costs associated with obtaining commitments for financing which result in a closing of such financing. These costs are amortized over the terms of the respective agreements. Unamortized deferred financing costs are expensed when the associated debt is refinanced or repaid before maturity. Costs incurred in seeking financing transactions, which do not close, are expensed in the period in which it is determined that the financing will not close.

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 costs, net 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.

December 31, 2015

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 provided that we have no substantial economic involvement with the buyer.

Interest income on debt and 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 debt and 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 is 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 an adjustment to the interest income over the terms of the related investments using the effective interest method. Fees received in connection with loan commitments are also 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 debt or 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 debt or preferred equity investment at a discount with the intention of foreclosing on the collateral, we do not accrete the discount. For debt investments acquired at a discount for credit quality, the difference between contractual cash flows and expected cash flows at acquisition is not accreted. Anticipated exit fees, the collection of which is expected, are also recognized over the term of the loan as an adjustment to yield.

Debt and 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 debt or preferred equity investment is resumed when such non-accrual debt or 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 the loans individually. When a transaction meets the criteria for 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, original issue discounts, 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 statements of operations. Any fees received at the time of sale or syndication are recognized as part of investment income.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our tenants to make required payments. If the financial condition of a specific tenant were to deteriorate, resulting in an impairment of its ability to make payments, additional allowances may be required.

Reserve for Possible Credit Losses

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

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the net fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during years ended December 31, 2015, 2014 and 2013.

Debt and preferred equity investments held for sale are carried at the lower of cost or fair market value using available market information obtained through consultation with dealers or other originators of such investments as well as discounted cash flow models based on Level 3 data pursuant to ASC 820-10. As circumstances change, management may conclude not to sell an

50

Notes to Consolidated Financial Statements (cont.)

December 31, 2015

investment designated as held for sale. In such situations, the investment will be reclassified at its net carrying value to debt and preferred equity investments held to maturity. For these reclassified investments, the difference between the current carrying value and the expected cash to be collected at maturity will be accreted into income over the remaining term of the investment.

Rent Expense

Rent expense is recognized on a straight-line basis over the initial term of the lease. The excess of the rent expense recognized over the amounts contractually due pursuant to the underlying lease is included in the deferred land leases payable on the consolidated balance sheets.

Income Taxes

ROP is a partnership and, as a result, all income and losses of the partnership are allocated to the partners for inclusion in their respective income tax returns. No provision has been made for income taxes in the consolidated financial statements since such taxes, if any, are the responsibility of the individual partners.

We follow a two-step approach for evaluating uncertain tax positions. Recognition (step one) occurs when an enterprise concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustained upon examination. Measurement (step two) determines the amount of benefit that is more-likely-than-not to be realized upon settlement. Derecognition of a tax position that was previously recognized would occur when a company subsequently determines that a tax position no longer meets the more-likely-than-not threshold of being sustained. The use of a valuation allowance as a substitute for derecognition of tax positions is prohibited.

Shares Contributed by Parent Company

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

Exchangeable Debt Instruments

The initial proceeds from exchangeable debt that may be settled in cash, including partial cash settlements, must be bifurcated between a liability component and an equity component associated with the embedded conversion option. The objective of the accounting guidance is to require the liability and equity components of exchangeable debt to be separately accounted for in a manner such that the interest expense on the exchangeable debt is not recorded at the stated rate of interest but rather at an effective rate that reflects the issuer's conventional debt borrowing rate at the date of issuance. We calculate the liability component of exchangeable debt based on the present value of the contractual cash flows discounted at our comparable market conventional debt borrowing rate at the date of issuance. The difference between the principal amount and the fair value of the liability component is reported as a discount on the exchangeable debt that is accreted as additional interest expense from the issuance date through the contractual maturity date using the effective interest method. A portion of this additional interest expense may be capitalized to the development and redevelopment balances qualifying for interest capitalization each period. The liability component of the exchangeable debt is reported net of discounts on our consolidated balance sheets. We calculate the equity component of exchangeable debt based on the difference between the initial proceeds received from the issuance of the exchangeable debt and the fair value of the liability component at the issuance date. The equity component is included in additional paid-in-capital, net of issuance costs, on our consolidated balance sheets. We allocate issuance costs for exchangeable debt between the liability and the equity components based on their relative values.

Fair Value Measurements

See Note 10, "Fair Value Measurements."

Derivative Instruments

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. Effectiveness is essential for those derivatives that we intend to qualify for hedge accounting. Some derivative instruments are associated with an anticipated transaction. In those cases, hedge effectiveness criteria also require that it be probable that the underlying transaction occurs. Instruments that meet these hedging criteria are formally designated as hedges at the inception of the derivative contract.

To determine the fair values of derivative instruments, we use a variety of methods and assumptions that are based on market conditions and risks existing at each balance sheet date. For the majority of financial instruments including most derivatives, long-term investments and long-term debt, standard market conventions and techniques such as discounted cash flow analysis, option pricing models, replacement cost, and termination cost are used to determine fair value. All methods of assessing fair value result in a general approximation of value, and such value may never actually be realized.

Notes to Consolidated Financial Statements (cont.)

December 31, 2015

In the normal course of business, we are exposed to the effect of interest rate changes and limit these risks by following established risk management policies and procedures including the use of derivatives. To address exposure to interest rates, derivatives are used primarily to fix the rate on debt based on floating-rate indices and manage the cost of borrowing obligations.

We use a variety of commonly used derivative products that are considered plain vanilla derivatives. These derivatives typically include interest rate swaps, caps, collars and floors. We expressly prohibit the use of unconventional derivative instruments and using derivative instruments for trading or speculative purposes. Further, we have a policy of only entering into contracts with major financial institutions based upon their credit ratings and other factors.

We may employ swaps, forwards or purchased options to hedge qualifying forecasted transactions. Gains and losses related to these transactions are deferred and recognized in net income as interest expense in the same period or periods that the underlying transaction occurs, expires or is otherwise terminated.

Hedges that are reported at fair value and presented on the balance sheet could be characterized as cash flow hedges or fair value hedges. Interest rate caps and collars are examples of cash flow hedges. Cash flow hedges address the risk associated with future cash flows of interest payments. For all hedges held by us and which were deemed to be fully effective in meeting the hedging objectives established by our corporate policy governing interest rate risk management, no net gains or losses were reported in earnings. The changes in fair value of hedge instruments are reflected in accumulated other comprehensive income. For derivative instruments not designated as hedging instruments, the gain or loss resulting from the change in the estimated fair value of the derivative instruments is recognized in current earnings during the period of change.

Earnings per Unit

Earnings per unit was not computed in 2015, 2014 and 2013 as there were no outstanding common units held by third parties at December 31, 2015, 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.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash investments, debt and preferred equity investments and accounts receivable. We place our cash investments in excess of insured amounts with high quality financial institutions. The collateral securing our debt and preferred equity investments is located in New York City. See Note 5, "Debt, 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 a space. Although the properties in our real estate portfolio are primarily located in Manhattan, we also have properties located in Brooklyn, Westchester County, Connecticut and New Jersey. The tenants located in our buildings operate in various industries. No tenant in the portfolio accounted for more than 5.0% of our share of annualized cash rent, including our share of joint venture annualized cash rent, at December 31, 2015. Approximately 15.4%, 9.7%, 8.2%, 7.7%, 7.5%, 7.2%, 6.7%, and 6.6% of our share of annualized cash rent was attributable to 1185 Avenue of the Americas, 625 Madison Avenue, 919 Third Avenue,750 Third Avenue, 810 Seventh Avenue, 1350 Avenue of the Americas, 555 West 57th Street, and 125 Park Avenue, respectively, for the year ended December 31, 2015. Annualized cash rent for all other consolidated properties was below 5.0%.

Reclassification

Certain prior year balances have been reclassified to conform to our current year presentation primarily in order to include the transfer of two properties, SL Green's tenancy in common interest in a fee interest and one entity that held debt investments and financing receivables in 2015.

Accounting Standards Updates

In February 2016, the Financial Accounting Standards Board, or FASB, issued guidance that amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted improvements to lessor accounting (Accounting Standards Update, or ASU, No. 2016-02). The guidance requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The guidance will be effective for fiscal years beginning after December 15, 2018, and interim periods

52

Reckson Operation Partnership, L.P.

Notes to Consolidated Financial Statements (cont.)

December 31, 2015

within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting this new accounting standard on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01 (ASC 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and to record changes in instruments-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income. The guidance is effective for fiscal years beginning after December 15, 2017, and for interim periods therein. The Company is currently evaluating the impact of adopting this new accounting standard on the Company’s consolidated financial statements.

In September 2015, the FASB issued final guidance to simplify the measurement-period adjustments in business combinations (ASU No. 2015-16). The guidance eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments in the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previously periods if the accounting had been completed at the acquisition date. The guidance is effective for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. Early adoption of the guidance is permitted. The Company adopted the guidance during the third quarter of 2015.

In April 2015, the FASB issued final guidance to simplify the presentation of debt issuance costs by requiring debt issuance costs to be presented as a deduction from the corresponding debt liability (ASU No. 2015-03). The guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The guidance is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption of the guidance is permitted. Upon adoption, an entity must apply the new guidance retrospectively for all prior periods presented in the financial statements. The Company adopted the guidance effective January 1, 2016 and the guidance did not have a material impact on our consolidated financial statements.

In February 2015, the FASB, issued new guidance that amends the current consolidation guidance, including introducing a separate consolidation analysis specific to limited partnerships and other similar entities (ASU No. 2015-02). Under this analysis, limited partnerships and other similar entities will be considered a VIE unless the limited partners hold substantive kick-out rights or participating rights.The guidance is effective for annual and interim periods beginning after December 15, 2015. Early adoption of this guidance is permitted. The Company adopted the guidance effective January 1, 2016 and the guidance did not have a material impact on our consolidated financial statements.

In June 2014, the FASB issued final guidance that requires repurchase-to-maturity transactions to be accounted for as secured borrowings as if the transferor retains effective control, even though the transferred financial assets are not returned to the transferor at settlement and also eliminates existing guidance for repurchase financings (ASU No. 2014-11). New disclosures are required for (1) certain transactions accounted for as secured borrowings and (2) transfers accounted for as sales when the transferor also retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. The guidance was effective for the first interim or annual period beginning after December 15, 2014, except for the disclosures related to transactions accounted for as secured borrowings, which are effective for periods beginning after March 15, 2015. Early adoption of this guidance is prohibited. The Company adopted the standard beginning in the third quarter of 2015 as a result of the transfer of one entity that held debt investments and financing receivables during the third quarter of 2015. The adoption of this guidance did not have a material impact on our consolidated financial statements.

In May 2014, the FASB issued a new comprehensive revenue recognition guidance which requires us to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods and services (ASU No. 2014-09). The guidance also requires enhanced disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. The guidance is effective for annual and interim periods beginning after December 15, 2016 and early adoption is not permitted. In July 2015, the FASB voted to defer by one year the effective date of ASU No. 2014-09 for both public and nonpublic entities and give both public and private companies the option to early adopt using the original effective date. The new guidance can be applied either retrospectively to each prior reporting period presented, or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements.

In April 2014, the FASB issued new guidance on reporting discontinued operations which raises the threshold for disposals to qualify as discontinued operations (ASU No. 2014-08). 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 was effective for calendar year public companies beginning in the first quarter of 2015 and

53

Reckson Operation Partnership, L.P.

Notes to Consolidated Financial Statements (cont.)

December 31, 2015

is to be applied on a prospective basis for new disposals. Early adoption of this guidance was permitted. The Company adopted the standard beginning in the first quarter of 2015. The adoption of this guidance changed the presentation of discontinued operations for all properties held for sale and/or disposed of subsequent to January 1, 2015.

3. Property Acquisitions

2015 Acquisition

In July 2015, we acquired the fee interest at 110 Greene Street for $255.0 million. We are currently in the process of analyzing the purchase price allocation and, as such, we have not allocated any value to intangible assets such as above-and below-market lease or in-place leases. We acquired a 90.0% controlling interest in this property for consideration that included the issuance of $5.0 million and $6.7 million aggregate liquidation preferences of Series P and Q Preferred Units, respectively, of limited partnership interest of the Operating Partnership and cash.

(1) During the year ended December 31, 2014, we finalized the purchase price allocation based on a third party appraisal and additional facts and circumstances that existed at the acquisition dates. These adjustments did not have a material impact to our consolidated statement of operations for the year ended December 31, 2014.

At December 31, 2015 and 2014, all debt and preferred equity investments were performing in accordance with the terms of the relevant investments, with the exception of a junior mortgage participation acquired in September 2014, which has a carrying value of zero.

We have determined that we have one portfolio segment of financing receivables at December 31, 2015 and 2014 comprising commercial real estate which is primarily recorded in debt and preferred equity investments. Included in other assets is an additional amount of financing receivables totaling $168.3 million and $107.0 million at December 31, 2015 and 2014, respectively. No financing receivables were 90 days past due at December 31, 2015.

Other Investments

Other investments pertain to investments accounted for under the equity method of accounting.

We have one debt and preferred equity investment which meets the criteria of a real estate investment under the guidance for Acquisition, Development and Construction arrangements and have accounted for this wholly owned investment under the equity method of accounting. As of December 31, 2015 and 2014, the book value of this investment was $100.2 million and $100.0 million, respectively. In January 2016 the maturity date of this investment was extended from March 2016 to March 2017, subject to two remaining one-year extension options and a two-year option for the last extension.

During the three months ended March 31, 2014, we sold our 43.74% economic ownership interest in the joint venture which holds the West Coast Office portfolio at an implied gross valuation of $756.0 million, inclusive of the $526.3 million mortgage encumbering the property. We recognized a gain of $85.6 million on the sale of our investment.

As of December 31, 2015, we have one investment in a real estate joint venture in which we do not control as a result of the level of our voting interest. The following table provides general information on our joint venture as of December 31, 2015:

These properties, which were previously wholly-owned, were accounted for in commercial real estate properties on the consolidated balance sheet. See Note 4, "Property Dispositions."

(1) Effective weighted average interest rate for the year ended December 31, 2015.

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

(3) In March 2015, we repaid the mortgage.

Master Repurchase Agreement

The Master Repurchase Agreement, as amended in December 2013, or MRA, provides us with the ability to sell certain debt investments with a simultaneous agreement to repurchase the same at a certain date or on demand. This MRA has a maximum facility capacity of $300.0 million and bears interest ranging from 250 basis points and 325 basis points over 30-day LIBOR depending on the pledged collateral. In September 2015, we entered into an amendment to the MRA to extend the maturity to June 29, 2016. Further, as of December 6, 2015 we are now required to pay monthly in arrears a 25 basis point fee on the excess of $150.0 million over the average daily balance during the period if the average daily balance is less than $150.0 million. We seek to mitigate risks associated with our repurchase agreement by managing the credit quality of our assets, early repayments, interest rate volatility, liquidity, and market value. The margin call provisions under our repurchase facility permit valuation adjustments based on capital markets activity, and are not limited to collateral-specific credit marks. To monitor credit risk associated with our debt investments, our asset management team regularly reviews our investment portfolio and is in contact with our borrowers in order to monitor the collateral and enforce our rights as necessary. The risk associated with potential margin calls is further mitigated by our ability to recollateralize the facility with additional assets from our portfolio of debt investments, our ability to satisfy margin calls with cash or cash equivalents and access to additional liquidity through the 2012 Credit Facility. See Note 7, "Corporate Indebtedness."

At December 31, 2015 and 2014, the gross book value of the properties and debt and preferred equity investments collateralizing the mortgages and other loans payable was approximately $2.0 billion and $1.9 billion, respectively.

7. Corporate Indebtedness

2012 Credit Facility

In July 2015, we entered into the third amendment to the credit facility that was originally entered into by the Company in November 2012, referred to as the 2012 credit facility, which increased our unsecured corporate facility by $500.0 million. The revolving credit facility was increased by $400.0 million to $1.6 billion and the term loan portion of the facility was increased by $100.0 million to $933.0 million.

In January 2015, we amended the 2012 credit facility by entering into a second amended and restated credit agreement, which decreased the interest-rate margin and facility fee applicable to the revolving credit facility by 20 basis points and five basis points, respectively, and extended the maturity date of the revolving credit facility to March 29, 2019 with an as-of-right extension through March 29, 2020.

In November 2014, we increased the term loan portion of the facility by $50.0 million to $833.0 million.

In March 2014, we entered into an amendment to the 2012 credit facility, which among other things, increased the term loan portion of the facility by $383.0 million to $783.0 million, decreased the interest-rate margin applicable to the term loan portion of the 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.

As of December 31, 2015, the 2012 credit facility, as amended, consisted of a $1.6 billion revolving credit facility, or the revolving credit facility, and a $933.0 million term loan, or the term loan facility. We also have an option, subject to customary conditions, to increase the capacity under the revolving credit facility to $3.0 billion at any time prior to the maturity date for the revolving credit facility without the consent of existing lenders, by obtaining additional commitments from our existing lenders and other financial institutions.

As of December 31, 2015, the 2012 credit facility bore interest at a spread over LIBOR ranging from (i) 87.5 basis points to 155 basis points for loans under the revolving credit facility and (ii) 95 basis points to 190 basis points for loans under the term loan facility, in each case based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. At December 31, 2015, the applicable spread was 125 basis points for revolving credit facility and 140 basis points for the term loan facility. At December 31, 2015, the effective interest rate was 1.45% for the revolving credit facility and 1.67% for the term loan facility. We are required to pay quarterly in arrears a 12.5 basis points to 30 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. As of December 31, 2015, the facility fee was 25 basis points. As of December 31, 2015, we had $73.1 million of outstanding letters of credit, $994.0 million drawn under the revolving credit facility and $933.0 million outstanding under the term loan facility, with total undrawn capacity of $532.9 million under the 2012 credit facility.

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

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

ROP also provides a guaranty of the Operating Partnership's obligations under its 3.00% Exchangeable Senior Notes due 2017.

Restrictive Covenants

The terms of the 2012 credit facility, as amended, and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, SL Green's ability to pay dividends, make certain types of investments, incur additional indebtedness, incur liens and enter into negative pledge agreements and dispose of assets, and which require compliance with financial ratios relating to the maximum ratio of total indebtedness to total asset value, a minimum ratio of EBITDA to fixed charges, a maximum ratio of secured indebtedness to total asset value and a maximum ratio of unsecured indebtedness to unencumbered asset value. The dividend restriction referred to above provides that SL Green will not during any time when a default is continuing, make distributions with respect to SL Green's common stock or other equity interests, except to enable SL Green to continue to qualify as a REIT for Federal income tax purposes. As of December 31, 2015 and 2014, we were in compliance with all such covenants.

8. Preferred Units

Through a consolidated subsidiary, we have authorized up to 109,1613.5% Series A Preferred Units of limited partnership interest, or the Greene Series A Preferred Units, with a liquidation preference of $1,000.00 per unit. In August 2015, the Company issued 109,161 Greene Series A Preferred Units in conjunction with an acquisition. The Greene Series A Preferred unitholders receive annual dividends of $35.00 per unit paid on a quarterly basis and dividends are cumulative, subject to certain provisions. The Greene Series A Preferred Units can be redeemed at any time, at the option of the unitholder, either for cash or are convertible on a one-for-one basis, into the Series B Preferred Units of limited partnership interest, or the Greene Series B Preferred Units. The Greene Series B Preferred Units can be converted at any time, at the option of the unitholder, into a number of common stock equal to 6.71348 shares of SL Green common stock for each Greene Series B Preferred Unit. As of December 31, 2015, no Greene Series B Preferred Units have been issued.

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

9. Partners' Capital

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

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

10. Fair Value Measurements

We are required to disclose fair value information with regard to our financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practical to estimate fair value. The FASB guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. We measure and/or disclose the estimated fair value of financial assets and liabilities based on a hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. This hierarchy 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. Our assessment of the significance of the particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

We determine other than temporary impairment in real estate investments and debt and preferred equity investments, including intangibles utilizing cash flow projections that apply, among other things, estimated revenue and expense growth rates, discount rates and capitalization rates, which are classified as Level 3 inputs.

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

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

The following table provides the carrying value and fair value of these financial instruments as of December 31, 2015 and 2014 (in thousands):

	December 31, 2015					December 31, 2014
	Carrying Value			Fair Value		Carrying Value			Fair Value
						(as adjusted)			(as adjusted)

(2) At December 31, 2015, debt and preferred equity investments had an estimated fair value ranging between $1.7 billion and $1.8 billion. At December 31, 2014, debt and preferred equity investments had an estimated fair value ranging between $1.5 billion and $1.8 billion.

Disclosure about fair value of financial instruments was based on pertinent information available to us as of December 31, 2015 and December 31, 2014. 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.

11. Financial Instruments: Derivatives and Hedging

In the normal course of business, we use a variety of commonly used derivative instruments, such as interest rate swaps, caps, collar and floors, to manage, or hedge interest rate risk. We hedge our exposure to variability in future cash flows for forecasted transactions in addition to anticipated future interest payments on existing debt. We recognize all derivatives on the balance sheets at fair value. Derivatives that are not hedges are adjusted to fair value through earnings. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedge asset, liability, or firm commitment through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. Reported net income and 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 December 31, 2015, 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 December 31, 2015 based on Level 2 inputs. The notional value is an indication of the extent of our involvement in that instrument at that time, but does not represent exposure to credit, interest rate or market risks.

	Notional Value	Strike Rate	Effective Date	Expiration Date	Balance Sheet Location	Fair Value
Interest Rate Swap	$30,000	2.295%	July 2010	June 2016	Other Liabilities	$	(241	)

Gains and losses on terminated hedges are included in the accumulated other comprehensive loss, and are recognized into earnings over the term of the related senior unsecured notes. As of December 31, 2015 and 2014, 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 $2.0 million and $2.3 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 $0.6 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 instrument that is designated and qualifies as a hedging instrument on the consolidated statements of operations for the years ended December 31, 2015, 2014 and 2013 respectively (in thousands):

	Amount of Loss Recognized in Other Comprehensive Loss (Effective Portion)								Location of Loss Reclassified from Accumulated Other Comprehensive Loss into Income	Amount of Gain  Reclassified from Accumulated Other Comprehensive Loss  into Income (Effective Portion)						Location of Gain Recognized in Income on Derivative	Amount of Gain  Recognized into Income (Ineffective Portion)

12. Rental Income

We are the lessor and the sublessor to tenants under operating leases with expiration dates ranging from January 1, 2016 to 2039. The minimum rental amounts due under the leases are generally either subject to scheduled fixed increases or adjustments. The leases generally also require that the tenants reimburse us for increases in certain operating costs and real estate taxes above their base year costs.

13. Related Party Transactions

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. Income earned from profit participation, which is included in other income on the consolidated statements of operations, was $3.3 million, $3.3 million and $3.0 million for the years ended December 31, 2015, 2014 and 2013 respectively. We also recorded expenses of $9.9 million, $9.1 million and $9.9 million for the years ended December 31, 2015, 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. Such amount was approximately $10.4 million, $9.8 million and $9.1 million for the years ended December 31, 2015, 2014 and 2013, respectively.

Insurance

We obtain insurance coverage through an insurance program administered by SL Green. In connection with this program, we incurred insurance expense of approximately $6.6 million, $6.4 million and $6.2 million for the years ended December 31, 2015, 2014 and 2013 respectively.

Related Party Receivable from SL Green

On July 22, 2015, our parent company issued a promissory note to us in the amount of $90.0 million, which bears interest at an annual rate of 6.0%, compounded quarterly, and matures on July 22, 2017.

14. Benefit Plans

The building employees are covered by multi-employer defined benefit pension plans and post-retirement health and welfare plans. We participate in the Building Service 32BJ, or Union, Pension Plan and Health Plan. The Pension Plan is a multi-employer, non-contributory defined benefit pension plan that was established under the terms of collective bargaining agreements between the Service Employees International Union, Local 32BJ, the Realty Advisory Board on Labor Relations, Inc. and certain other employees. This Pension Plan is administered by a joint board of trustees consisting of union trustees and employer trustees and operates under employer identification number 13-1879376. The Pension Plan year runs from July 1 to June 30. Employers contribute to the Pension Plan at a fixed rate on behalf of each covered employee. Separate actuarial information regarding such pension plans is not made available to the contributing employers by the union administrators or trustees, since the plans do not maintain separate records for each reporting unit. However, on September 28, 2013, September 30, 2014, and September 28, 2015, the actuary certified that for the plan years beginning July 1, 2013, July 1, 2014 and July 1, 2015, respectively, the Pension Plan was in critical status under the Pension Protection Act of 2006. The Pension Plan trustees adopted a rehabilitation plan consistent with this requirement. No surcharges have been paid to the Pension Plan as of December 31, 2015. The Pension Plan received

65

Notes to Consolidated Financial Statements (cont.)

December 31, 2015

contributions from employers totaling $242.3 million, $226.7 million and $221.9 million, for the plan years beginning July 1, 2012, July 2013 and July 2014, respectively.

The Health Plan was established under the terms of collective bargaining agreements between the Union, the Realty Advisory Board on Labor Relations, Inc. and certain other employers. The Health Plan provides health and other benefits to eligible participants employed in the building service industry who are covered under collective bargaining agreements, or other written agreements, with the Union. The Health Plan is administered by a Board of Trustees with equal representation by the employers and the Union and operates under employer identification number 13-2928869. The Health Plan receives contributions in accordance with collective bargaining agreements or participation agreements. Generally, these agreements provide that the employers contribute to the Health Plan at a fixed rate on behalf of each covered employee. For the Health plan years ended, June 30, 2015, 2014 and 2013, the plan received contributions from employers totaling $1.1 billion, $1.0 billion and $923.5 million, respectively. Our contributions to the Health Plan represent less than 5.0% of total contributions to the plan.

Contributions we made to the multi-employer plans for the years ended December 31, 2015, 2014 and 2013 are included in the table below (in thousands):

15. Commitments and Contingencies

Legal Proceedings

As of December 31, 2015, we were not involved in any material litigation nor, to management's knowledge, was any material litigation threatened against us or our portfolio which if adversely determined could have a material adverse impact on us other than routine litigation arising in the ordinary course of business or litigation that is adequately covered by insurance.

Environmental Matters

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

Ground Leases Arrangements

The property located at 711 Third Avenue operates under an operating sub-lease, which expires in 2083. The ground rent was reset in July 2011. Following the reset, we are responsible for ground rent payments of $5.25 million annually through July 2016 and then $5.5 million annually thereafter on the 50% portion of the fee that we do not own.

The property located at 461 Fifth Avenue operates under a ground lease ($2.1 million of ground rent annually) with an expiration date of 2027 and two options to renew for an additional 21 years each, followed by a third option for 15 years. We also have an option to purchase the fee position for a fixed price on a specific date.

The property located at 625 Madison Avenue operates under a ground lease ($4.6 million of ground rent annually) with an expiration date of 2022 and two options to renew for an additional 23 years.

The property located at 1185 Avenue of the Americas operates under a ground lease ($6.9 million of ground rent annually) with an expiration of 2043 and an option to renew for an additional 23 years.

16. Segment Information

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

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

Selected results of operations for the years ended December 31, 2015, 2014 and 2013 and selected asset information as of December 31, 2015 and 2014, regarding our operating segments are as follows (in thousands):

December 31, 2014, as adjusted	6,671,984		1,631,789		8,303,773

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 debt and preferred equity segment. Interest costs for the debt and preferred equity segment are imputed assuming the portfolio is 100% leveraged by our 2012 revolving credit facility borrowing cost and corporate borrowing cost. We also allocate loan loss reserves, net of recoveries and transaction related costs to the debt and preferred equity segment. We do not allocate marketing, general and administrative expenses to the debt and preferred equity segment, since we base performance on the

ITEM 9.    CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including the principal executive officer and principal financial officer of our general partner, as appropriate, to allow timely decisions regarding required disclosure based closely on the definition of "disclosure controls and procedures" in Rule 13a-15(e) of the Exchange Act. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within ROP to disclose material information otherwise required to be set forth in our periodic reports.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including the President and Treasurer of our general partner, of the effectiveness of the design and operation of our disclosure controls and procedures. Based upon that evaluation as of the end of the period covered by this report, the President and Treasurer of our general partner concluded that our disclosure controls and procedures were effective to give reasonable assurances to the timely collection, evaluation and disclosure of information relating to ROP that would potentially be subject to disclosure under the Exchange Act and the rules and regulations promulgated thereunder.

Management's Report on Internal Control over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15 (f) and 15d-15 (f). Under the supervision and with the participation of our management, including the President and Treasurer of our general partner, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2015 based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (COSO). Based on that evaluation, we concluded that our internal control over financial reporting was effective as of December 31, 2015.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree or compliance with the policies or procedures may deteriorate.

This annual report does not include an attestation report of ROP's registered public accounting firm regarding internal control over financial reporting. Management's report was not subject to attestation by ROP's registered public accounting firm pursuant to rules of the SEC that permits ROP to provide only management's report in this annual report.

Changes in Internal Control over Financial Reporting

There have been no significant changes in our internal control over financial reporting during the year ended December 31, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 9B.    OTHER INFORMATION

PART III

ITEMS 10, 11, 12 AND 13.

As discussed in this report, SL Green acquired us on January 25, 2007. WAGP is the sole general partner of ROP and WAGP is a wholly-owned subsidiary of the Operating Partnership. The directors and officers of WAGP also serve as officers of SL Green. As a result, you should read SL Green's Definitive Proxy Statement for its 2016 Annual Meeting of Stockholders to be filed pursuant to Regulation 14A under the Exchange Act, on or prior to April 30, 2014, for the information required by Items 10, 11, 12 and 13 with respect to SL Green and which is incorporated herein by reference.

ITEM 14.    PRINCIPAL ACCOUNTING FEES AND SERVICES

Ernst & Young LLP has served as ROP's independent registered public accounting firm since ROP's formation in September 1994 and is considered by management of ROP to be well qualified. ROP has been advised by that firm that neither it nor any member thereof has any financial interest, direct or indirect, in ROP or any of its subsidiaries in any capacity.

Ernst & Young LLP's fees for providing services to ROP in 2015 and 2014 were as follows:

Audit Fees.    The aggregate fees billed by Ernst & Young LLP for professional services rendered for the audit of ROP's annual financial statements for the years ended December 31, 2015 and 2014 and for the reviews of the financial statements included in ROP's Quarterly Reports on Form 10-Q for the years ended December 31, 2015 and 2014 were approximately $415,000 and $371,000 respectively.

Audit Related Fees.    The audit related fees paid to Ernst & Young LLP for professional services rendered for assurance and related services that are reasonably related to the performance of the audit or review of ROP's financial statements, other than the services described under "Audit Fees," including due diligence and accounting assistance relating to transactions, joint ventures and other matters, were $25,000 for each of the years ended December 31, 2015 and 2014, respectively.

Tax Fees.    There were no tax fees billed by Ernst & Young LLP for professional services rendered for tax compliance (including REIT tax compliance), tax advice and tax planning for the years ended December 31, 2015 and 2014, respectively.

All Other Fees.    There were no other fees billed by Ernst & Young LLP for the years ended December 31, 2015 and 2014.

WAGP is not required to have an audit committee and WAGP in fact does not have an audit committee. Management has the primary responsibility for the preparation, presentation and integrity of our financial statements, accounting and financial reporting principles, internal controls and procedures designed to ensure compliance with accounting standards, applicable laws and regulations.

Management has reviewed and discussed the audited financial statements with Ernst & Young LLP, our independent registered public accounting firm, who is responsible for auditing our financial statements and for expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States, their judgments as to the quality, not just the acceptability, of our accounting principles and such other matters as are required to be discussed under Statement on Auditing Standards No. 61, as adopted by the Public Company Accounting Oversight Board in Rule 3200T. Management received from Ernst & Young LLP the written disclosures and the letter required by the applicable requirements of the Public Company Accounting Oversight Board regarding communications concerning independence, discussed with Ernst & Young LLP their independence from both management and the Company and considered the compatibility of Ernst & Young LLP's provision of non-audit services to the Company with their independence.

Management recommended to the board of directors of our sole general partner (and such board of directors has approved) that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2015 for filing with the SEC.

With respect to Reckson Operating Partnership, L.P., fixed charges consist of interest expense including the amortization of debt issuance costs and rental expense deemed to represent interest expense.

Organization and Basis of Presentation

Organization and Basis of Presentation

Reckson Operating Partnership, L.P., or ROP, commenced operations on June 2, 1995. The sole general partner of ROP is Wyoming Acquisition GP LLC., or WAGP, a wholly-owned subsidiary of SL Green Operating Partnership, L.P., or the Operating Partnership. The sole limited partner of ROP is the Operating Partnership. The Operating Partnership is 96.39% owned by SL Green Realty Corp., or SL Green, as of December 31, 2015. SL Green is a self-administered and self-managed real estate investment trust, and is the sole managing general partner of the Operating Partnership. Unless the context requires otherwise, all references to "we," "our," "us" and the "Company" means ROP and all entities owned or controlled by ROP.

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

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.

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 2015, SL Green transferred two properties and SL Green's tenancy in common interest in a fee interest with a total value of $395.0 million to ROP. Additionally, in 2015, SL Green transferred one entity that held debt investments and financing receivables with an aggregate carrying value of $1.7 billion to ROP. During 2014, SL Green transferred five properties with a total value aggregating $884.3 million to ROP. These transfers were made to further diversify ROP's portfolio. Under the business combinations guidance (Accounting Standard Codification, or ASC, 805-50), these transfers were determined to be transfers of businesses between the indirect parent company and its wholly-owned subsidiary. As such, the assets and liabilities of the properties were transferred at their carrying values and were recorded as of the beginning of the current reporting period as though the assets and liabilities had been transferred at that date. The financial statements and financial information presented for all prior periods have been retrospectively adjusted to furnish comparative information.

As of December 31, 2015, we owned the following interests in properties in the New York Metropolitan area, primarily in midtown Manhattan. Our investments in the New York Metropolitan area also include investments in Brooklyn, Westchester County, Connecticut and New Jersey, which are collectively known as the Suburban properties:

Location	Type	Number of Properties	Approximate Square Feet (unaudited)	Weighted Average Occupancy(1) (unaudited)

Manhattan	Office	16	8,463,245	94.9	%

____________________________________________________________________

(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 December 31, 2015, we owned a building that was comprised of approximately 270,132 square feet (unaudited) of retail space and approximately 222,855 square feet (unaudited) of residential space. For the purpose of this report, we have included the building in the retail properties count and have bifurcated the square footage into the retail and residential components.

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

As of December 31, 2015, we also held debt, preferred equity and other investments with a book value of $1.8 billion.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include our accounts and those of our subsidiaries, which are wholly-owned or controlled by us. Entities which we do not control through our voting interest and entities which are variable interest entities, but where we are not the primary beneficiary, are accounted for under the equity method or as preferred equity investments. See Note 5, "Debt, 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 the primary beneficiary. The primary beneficiary is the entity that has (i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE.

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 is modified to present earnings and other comprehensive income attributed to controlling and noncontrolling interests.

We assess the accounting treatment for each joint venture and debt 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 VIEs, 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, 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 the joint venture. Our joint venture agreements typically contain certain protective rights such as requiring 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

Real estate properties are presented at cost less accumulated depreciation and amortization. Costs directly related to the development or redevelopment of properties are capitalized. Ordinary repairs and maintenance are expensed as incurred; major replacements and betterments, which improve or extend the life of the asset, are capitalized and depreciated over their estimated useful lives.

A property to be disposed of is reported at the lower of its carrying value or its estimated fair value, less its cost to sell. Once an asset is held for sale, depreciation expense is no longer recorded. The Company adopted ASU 2014-08 effective January 1, 2015. As a result, the Company classified 140 Grand Street in White Plains, New York as held for sale as of September 30, 2015, and 131-137 Spring Street as of June 30, 2015 and included the results of operations in continuing operations for all periods presented. Discontinued operations included the results of operations of real estate assets sold or held for sale prior to January 1, 2015. This included 673 First Avenue, which was sold during 2014. See Note 4, "Property Dispositions."

Properties are depreciated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives are as follows:

Category	Term
Building (fee ownership)	40 years
Building improvements	shorter of remaining life of the building or useful life
Building (leasehold interest)	lesser of 40 years or remaining term of the lease
Property under capital lease	remaining lease term
Furniture and fixtures	four to seven years
Tenant improvements	shorter of remaining term of the lease or useful life

Depreciation expense (including amortization of the capital lease asset) amounted to $187.2 million, $184.3 million and $170.0 million for the years ended December 31, 2015, 2014 and 2013, respectively.

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted 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 either their carrying value or fair value less costs to sell. During the three months ended September 30, 2015, we recorded a $10.0 million charge in connection with the expected sale of one of our properties, which closed in the fourth quarter of 2015. This charge is included in depreciable real estate reserves in the consolidated statements of operations. Prior to the quarter ended September 30, 2015, we do not believe that there were any indicators of impairment at this property. See Note 4, "Property Dispositions." We do not believe that there were any indicators of impairment at any of our consolidated properties at December 31, 2015.

We incur a variety of costs in the development and leasing of our properties. After determination is made to capitalize a cost, it is allocated to the specific component of a project that is benefited. Determination of when a development project is substantially complete and capitalization must cease involves a degree of judgment. The costs of land and building under development include specifically identifiable costs. The capitalized costs include, but are not limited to, pre-construction costs essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. We consider a construction project as substantially completed and held available for occupancy upon the completion of tenant improvements, but no later than one year after major construction activity ceases. We cease capitalization on the portions substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portions under construction.

We recognize the assets acquired, liabilities assumed (including contingencies) and any noncontrolling interests in an acquired entity at their fair values on the acquisition date. We expense transaction costs related to the acquisition of certain assets as incurred, which are included in transaction related costs on our consolidated statements of operations. Results of operations of properties acquired are included in the consolidated statements of operations from the date of acquisition.

We allocate the purchase price of real estate to land and building (inclusive of tenant improvements) and, if determined to be material, intangibles, such as the value of above- and below-market leases and origination costs associated with the in-place leases. We depreciate the amount allocated to building (inclusive of tenant improvements) over their estimated useful lives, which generally range from three to 40 years. We amortize the amount allocated to the above- and below-market leases over the remaining term of the associated lease, which generally range from one to 14 years, and record it as either an increase (in the case of below-market leases) or a decrease (in the case of above-market leases) to rental income. We amortize the amount allocated to the values associated with in-place leases over the expected term of the associated lease, which generally ranges from one to 14 years. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off. The tenant improvements and origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). We assess fair value of the leases based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and market/economic conditions that may affect the property. To the extent acquired leases contain fixed rate renewal options that are below-market and determined to be material, we amortize such below-market lease value into rental income over the renewal period. As of December 31, 2015, the weighted average amortization period for above-market leases, below-market leases, and in-place lease costs is 4.4 years, 13.3 years, and 11.9 years, respectively.

We recognized $24.9 million, $21.0 million, and $19.0 million of rental revenue for the years ended December 31, 2015, 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. The increase in rental revenue for the year ended December 31, 2013 is net of $6.8 million resulting from the write-off of balances associated with a former tenant. Excluding this non-recurring charge, we recognized an increase of $25.8 million in rental revenue for the year ended December 31, 2013 for the amortization of aggregate below-market leases in excess of above-market leases and reductions in lease origination costs. In March 2014, we recognized income of $0.3 million for the amortization of the remaining value of below-market rate mortgage at 16 Court Street, Brooklyn, as a result of early repayment of debt. Excluding this one-time income, we recognized as a reduction to interest expense the amortization of the above-market rate mortgages assumed of $2.1 million for the year ended December 31, 2014. We recognized as an increase (a reduction) to interest expense the amortization of the above-market rate mortgages assumed of $0.4 million and $(2.5) million for the years ended December 31, 2015 and 2013, 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 December 31, 2015 and 2014 (in thousands):

	December 31, 2015			December 31, 2014
				(as adjusted)
Identified intangible assets (included in other assets):
Gross amount	$	307,824		$	297,238
Accumulated amortization	(235,040		)	(216,841		)
Net	$	72,784		$	80,397

Accumulated amortization	(346,857		)	(322,694		)
Net	$	176,371		$	127,632

The estimated annual amortization of acquired below-market leases, net of acquired above-market leases (a component of rental revenue), for each of the five succeeding years is as follows (in thousands):

2016	$	3,017
2017	4,994
2018	6,548
2019	7,128
2020	6,919

The estimated annual amortization of all other identifiable assets (a component of depreciation and amortization expense) including tenant improvements for each of the five succeeding years is as follows (in thousands):

2016	$	4,600
2017	3,326
2018	2,177
2019	1,751
2020	1,588

Investment in Unconsolidated Joint Ventures

We account for our investment in the unconsolidated joint venture under the equity method of accounting in cases where we exercise significant influence, but do not control the entity and are not considered to be the primary beneficiary. We consolidate those 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 we are determined to be the primary beneficiary in a VIE, these participating rights preclude us from consolidating these VIE entities. These investments are recorded initially at cost, as investments in unconsolidated joint ventures, and subsequently adjusted for equity in net income (loss) and cash contributions and distributions. Equity in net income (loss) from unconsolidated joint ventures 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. None of the joint venture debt is recourse to us. See Note 5, "Debt, Preferred Equity and Other Investments."

We assess our investments in unconsolidated joint ventures for recoverability, and if it is determined that a loss in value of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments for impairment based on the joint venture's projected discounted cash flows. We do not believe that the values of any of our equity investments were impaired at December 31, 2015.

We may originate loans for real estate acquisition, development and construction, where we expect to receive some of the residual profit from such projects. When the risk and rewards of these arrangements are essentially the same as an investor or joint venture partner, we account for these arrangements as real estate investments under the equity method of accounting for investments. Otherwise, we account for these arrangements consistent with our loan accounting for our debt and preferred equity investments.

Cash and Cash Equivalents

We consider all highly liquid investments with maturity of three months or less when purchased to be cash equivalents.

Restricted Cash

Restricted cash primarily consists of security deposits held on behalf of our tenants, interest reserves, as well as capital improvement and real estate tax escrows required under certain loan agreements.

Deferred Lease Costs

Deferred lease costs consist of fees and direct costs incurred to initiate and renew operating leases and are amortized on a straight-line basis over the related lease term.

Deferred Financing Costs

Deferred financing costs represent commitment fees, legal, title and other third party costs associated with obtaining commitments for financing which result in a closing of such financing. These costs are amortized over the terms of the respective agreements. Unamortized deferred financing costs are expensed when the associated debt is refinanced or repaid before maturity. Costs incurred in seeking financing transactions, which do not close, are expensed in the period in which it is determined that the financing will not close.

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 costs, net 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 provided that we have no substantial economic involvement with the buyer.

Interest income on debt and 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 debt and 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 is 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 an adjustment to the interest income over the terms of the related investments using the effective interest method. Fees received in connection with loan commitments are also 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 debt or 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 debt or preferred equity investment at a discount with the intention of foreclosing on the collateral, we do not accrete the discount. For debt investments acquired at a discount for credit quality, the difference between contractual cash flows and expected cash flows at acquisition is not accreted. Anticipated exit fees, the collection of which is expected, are also recognized over the term of the loan as an adjustment to yield.

Debt and 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 debt or preferred equity investment is resumed when such non-accrual debt or 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 the loans individually. When a transaction meets the criteria for 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, original issue discounts, 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 statements of operations. Any fees received at the time of sale or syndication are recognized as part of investment income.

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our tenants to make required payments. If the financial condition of a specific tenant were to deteriorate, resulting in an impairment of its ability to make payments, additional allowances may be required.

Reserve for Possible Credit Losses

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

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the net fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during years ended December 31, 2015, 2014 and 2013.

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

Rent Expense

Rent expense is recognized on a straight-line basis over the initial term of the lease. The excess of the rent expense recognized over the amounts contractually due pursuant to the underlying lease is included in the deferred land leases payable on the consolidated balance sheets.

Income Taxes

ROP is a partnership and, as a result, all income and losses of the partnership are allocated to the partners for inclusion in their respective income tax returns. No provision has been made for income taxes in the consolidated financial statements since such taxes, if any, are the responsibility of the individual partners.

We follow a two-step approach for evaluating uncertain tax positions. Recognition (step one) occurs when an enterprise concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustained upon examination. Measurement (step two) determines the amount of benefit that is more-likely-than-not to be realized upon settlement. Derecognition of a tax position that was previously recognized would occur when a company subsequently determines that a tax position no longer meets the more-likely-than-not threshold of being sustained. The use of a valuation allowance as a substitute for derecognition of tax positions is prohibited.

Shares Contributed by Parent Company

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

Exchangeable Debt Instruments

The initial proceeds from exchangeable debt that may be settled in cash, including partial cash settlements, must be bifurcated between a liability component and an equity component associated with the embedded conversion option. The objective of the accounting guidance is to require the liability and equity components of exchangeable debt to be separately accounted for in a manner such that the interest expense on the exchangeable debt is not recorded at the stated rate of interest but rather at an effective rate that reflects the issuer's conventional debt borrowing rate at the date of issuance. We calculate the liability component of exchangeable debt based on the present value of the contractual cash flows discounted at our comparable market conventional debt borrowing rate at the date of issuance. The difference between the principal amount and the fair value of the liability component is reported as a discount on the exchangeable debt that is accreted as additional interest expense from the issuance date through the contractual maturity date using the effective interest method. A portion of this additional interest expense may be capitalized to the development and redevelopment balances qualifying for interest capitalization each period. The liability component of the exchangeable debt is reported net of discounts on our consolidated balance sheets. We calculate the equity component of exchangeable debt based on the difference between the initial proceeds received from the issuance of the exchangeable debt and the fair value of the liability component at the issuance date. The equity component is included in additional paid-in-capital, net of issuance costs, on our consolidated balance sheets. We allocate issuance costs for exchangeable debt between the liability and the equity components based on their relative values.

Fair Value Measurements

See Note 10, "Fair Value Measurements."

Derivative Instruments

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. Effectiveness is essential for those derivatives that we intend to qualify for hedge accounting. Some derivative instruments are associated with an anticipated transaction. In those cases, hedge effectiveness criteria also require that it be probable that the underlying transaction occurs. Instruments that meet these hedging criteria are formally designated as hedges at the inception of the derivative contract.

To determine the fair values of derivative instruments, we use a variety of methods and assumptions that are based on market conditions and risks existing at each balance sheet date. For the majority of financial instruments including most derivatives, long-term investments and long-term debt, standard market conventions and techniques such as discounted cash flow analysis, option pricing models, replacement cost, and termination cost are used to determine fair value. All methods of assessing fair value result in a general approximation of value, and such value may never actually be realized.

In the normal course of business, we are exposed to the effect of interest rate changes and limit these risks by following established risk management policies and procedures including the use of derivatives. To address exposure to interest rates, derivatives are used primarily to fix the rate on debt based on floating-rate indices and manage the cost of borrowing obligations.

We use a variety of commonly used derivative products that are considered plain vanilla derivatives. These derivatives typically include interest rate swaps, caps, collars and floors. We expressly prohibit the use of unconventional derivative instruments and using derivative instruments for trading or speculative purposes. Further, we have a policy of only entering into contracts with major financial institutions based upon their credit ratings and other factors.

We may employ swaps, forwards or purchased options to hedge qualifying forecasted transactions. Gains and losses related to these transactions are deferred and recognized in net income as interest expense in the same period or periods that the underlying transaction occurs, expires or is otherwise terminated.

Hedges that are reported at fair value and presented on the balance sheet could be characterized as cash flow hedges or fair value hedges. Interest rate caps and collars are examples of cash flow hedges. Cash flow hedges address the risk associated with future cash flows of interest payments. For all hedges held by us and which were deemed to be fully effective in meeting the hedging objectives established by our corporate policy governing interest rate risk management, no net gains or losses were reported in earnings. The changes in fair value of hedge instruments are reflected in accumulated other comprehensive income. For derivative instruments not designated as hedging instruments, the gain or loss resulting from the change in the estimated fair value of the derivative instruments is recognized in current earnings during the period of change.

Earnings per Unit

Earnings per unit was not computed in 2015, 2014 and 2013 as there were no outstanding common units held by third parties at December 31, 2015, 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.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash investments, debt and preferred equity investments and accounts receivable. We place our cash investments in excess of insured amounts with high quality financial institutions. The collateral securing our debt and preferred equity investments is located in New York City. See Note 5, "Debt, 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 a space. Although the properties in our real estate portfolio are primarily located in Manhattan, we also have properties located in Brooklyn, Westchester County, Connecticut and New Jersey. The tenants located in our buildings operate in various industries. No tenant in the portfolio accounted for more than 5.0% of our share of annualized cash rent, including our share of joint venture annualized cash rent, at December 31, 2015. Approximately 15.4%, 9.7%, 8.2%, 7.7%, 7.5%, 7.2%, 6.7%, and 6.6% of our share of annualized cash rent was attributable to 1185 Avenue of the Americas, 625 Madison Avenue, 919 Third Avenue,750 Third Avenue, 810 Seventh Avenue, 1350 Avenue of the Americas, 555 West 57th Street, and 125 Park Avenue, respectively, for the year ended December 31, 2015. Annualized cash rent for all other consolidated properties was below 5.0%.

Reclassification

Certain prior year balances have been reclassified to conform to our current year presentation primarily in order to include the transfer of two properties, SL Green's tenancy in common interest in a fee interest and one entity that held debt investments and financing receivables in 2015.

Accounting Standards Updates

In February 2016, the Financial Accounting Standards Board, or FASB, issued guidance that amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted improvements to lessor accounting (Accounting Standards Update, or ASU, No. 2016-02). The guidance requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The guidance will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting this new accounting standard on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01 (ASC 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and to record changes in instruments-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income. The guidance is effective for fiscal years beginning after December 15, 2017, and for interim periods therein. The Company is currently evaluating the impact of adopting this new accounting standard on the Company’s consolidated financial statements.

In September 2015, the FASB issued final guidance to simplify the measurement-period adjustments in business combinations (ASU No. 2015-16). The guidance eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments in the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previously periods if the accounting had been completed at the acquisition date. The guidance is effective for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. Early adoption of the guidance is permitted. The Company adopted the guidance during the third quarter of 2015.

In April 2015, the FASB issued final guidance to simplify the presentation of debt issuance costs by requiring debt issuance costs to be presented as a deduction from the corresponding debt liability (ASU No. 2015-03). The guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The guidance is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption of the guidance is permitted. Upon adoption, an entity must apply the new guidance retrospectively for all prior periods presented in the financial statements. The Company adopted the guidance effective January 1, 2016 and the guidance did not have a material impact on our consolidated financial statements.

In February 2015, the FASB, issued new guidance that amends the current consolidation guidance, including introducing a separate consolidation analysis specific to limited partnerships and other similar entities (ASU No. 2015-02). Under this analysis, limited partnerships and other similar entities will be considered a VIE unless the limited partners hold substantive kick-out rights or participating rights.The guidance is effective for annual and interim periods beginning after December 15, 2015. Early adoption of this guidance is permitted. The Company adopted the guidance effective January 1, 2016 and the guidance did not have a material impact on our consolidated financial statements.

In June 2014, the FASB issued final guidance that requires repurchase-to-maturity transactions to be accounted for as secured borrowings as if the transferor retains effective control, even though the transferred financial assets are not returned to the transferor at settlement and also eliminates existing guidance for repurchase financings (ASU No. 2014-11). New disclosures are required for (1) certain transactions accounted for as secured borrowings and (2) transfers accounted for as sales when the transferor also retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. The guidance was effective for the first interim or annual period beginning after December 15, 2014, except for the disclosures related to transactions accounted for as secured borrowings, which are effective for periods beginning after March 15, 2015. Early adoption of this guidance is prohibited. The Company adopted the standard beginning in the third quarter of 2015 as a result of the transfer of one entity that held debt investments and financing receivables during the third quarter of 2015. The adoption of this guidance did not have a material impact on our consolidated financial statements.

In May 2014, the FASB issued a new comprehensive revenue recognition guidance which requires us to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods and services (ASU No. 2014-09). The guidance also requires enhanced disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. The guidance is effective for annual and interim periods beginning after December 15, 2016 and early adoption is not permitted. In July 2015, the FASB voted to defer by one year the effective date of ASU No. 2014-09 for both public and nonpublic entities and give both public and private companies the option to early adopt using the original effective date. The new guidance can be applied either retrospectively to each prior reporting period presented, or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements.

In April 2014, the FASB issued new guidance on reporting discontinued operations which raises the threshold for disposals to qualify as discontinued operations (ASU No. 2014-08). 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 was 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 this guidance was permitted. The Company adopted the standard beginning in the first quarter of 2015. The adoption of this guidance changed the presentation of discontinued operations for all properties held for sale and/or disposed of subsequent to January 1, 2015.

2015 Acquisition

In July 2015, we acquired the fee interest at 110 Greene Street for $255.0 million. We are currently in the process of analyzing the purchase price allocation and, as such, we have not allocated any value to intangible assets such as above-and below-market lease or in-place leases. We acquired a 90.0% controlling interest in this property for consideration that included the issuance of $5.0 million and $6.7 million aggregate liquidation preferences of Series P and Q Preferred Units, respectively, of limited partnership interest of the Operating Partnership and cash.

We have one debt and preferred equity investment which meets the criteria of a real estate investment under the guidance for Acquisition, Development and Construction arrangements and have accounted for this wholly owned investment under the equity method of accounting. As of December 31, 2015 and 2014, the book value of this investment was $100.2 million and $100.0 million, respectively. In January 2016 the maturity date of this investment was extended from March 2016 to March 2017, subject to two remaining one-year extension options and a two-year option for the last extension.

During the three months ended March 31, 2014, we sold our 43.74% economic ownership interest in the joint venture which holds the West Coast Office portfolio at an implied gross valuation of $756.0 million, inclusive of the $526.3 million mortgage encumbering the property.

Master Repurchase Agreement

The Master Repurchase Agreement, as amended in December 2013, or MRA, provides us with the ability to sell certain debt investments with a simultaneous agreement to repurchase the same at a certain date or on demand. This MRA has a maximum facility capacity of $300.0 million and bears interest ranging from 250 basis points and 325 basis points over 30-day LIBOR depending on the pledged collateral. In September 2015, we entered into an amendment to the MRA to extend the maturity to June 29, 2016. Further, as of December 6, 2015 we are now required to pay monthly in arrears a 25 basis point fee on the excess of $150.0 million over the average daily balance during the period if the average daily balance is less than $150.0 million. We seek to mitigate risks associated with our repurchase agreement by managing the credit quality of our assets, early repayments, interest rate volatility, liquidity, and market value. The margin call provisions under our repurchase facility permit valuation adjustments based on capital markets activity, and are not limited to collateral-specific credit marks. To monitor credit risk associated with our debt investments, our asset management team regularly reviews our investment portfolio and is in contact with our borrowers in order to monitor the collateral and enforce our rights as necessary. The risk associated with potential margin calls is further mitigated by our ability to recollateralize the facility with additional assets from our portfolio of debt investments, our ability to satisfy margin calls with cash or cash equivalents and access to additional liquidity through the 2012 Credit Facility. See Note 7, "Corporate Indebtedness."

At December 31, 2015 and 2014, the gross book value of the properties and debt and preferred equity investments collateralizing the mortgages and other loans payable was approximately $2.0 billion and $1.9 billion, respectively.

2012 Credit Facility

In July 2015, we entered into the third amendment to the credit facility that was originally entered into by the Company in November 2012, referred to as the 2012 credit facility, which increased our unsecured corporate facility by $500.0 million. The revolving credit facility was increased by $400.0 million to $1.6 billion and the term loan portion of the facility was increased by $100.0 million to $933.0 million.

In January 2015, we amended the 2012 credit facility by entering into a second amended and restated credit agreement, which decreased the interest-rate margin and facility fee applicable to the revolving credit facility by 20 basis points and five basis points, respectively, and extended the maturity date of the revolving credit facility to March 29, 2019 with an as-of-right extension through March 29, 2020.

In November 2014, we increased the term loan portion of the facility by $50.0 million to $833.0 million.

In March 2014, we entered into an amendment to the 2012 credit facility, which among other things, increased the term loan portion of the facility by $383.0 million to $783.0 million, decreased the interest-rate margin applicable to the term loan portion of the 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.

As of December 31, 2015, the 2012 credit facility, as amended, consisted of a $1.6 billion revolving credit facility, or the revolving credit facility, and a $933.0 million term loan, or the term loan facility. We also have an option, subject to customary conditions, to increase the capacity under the revolving credit facility to $3.0 billion at any time prior to the maturity date for the revolving credit facility without the consent of existing lenders, by obtaining additional commitments from our existing lenders and other financial institutions.

As of December 31, 2015, the 2012 credit facility bore interest at a spread over LIBOR ranging from (i) 87.5 basis points to 155 basis points for loans under the revolving credit facility and (ii) 95 basis points to 190 basis points for loans under the term loan facility, in each case based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. At December 31, 2015, the applicable spread was 125 basis points for revolving credit facility and 140 basis points for the term loan facility. At December 31, 2015, the effective interest rate was 1.45% for the revolving credit facility and 1.67% for the term loan facility. We are required to pay quarterly in arrears a 12.5 basis points to 30 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. As of December 31, 2015, the facility fee was 25 basis points. As of December 31, 2015, we had $73.1 million of outstanding letters of credit, $994.0 million drawn under the revolving credit facility and $933.0 million outstanding under the term loan facility, with total undrawn capacity of $532.9 million under the 2012 credit facility.

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

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

Restrictive Covenants

The terms of the 2012 credit facility, as amended, and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, SL Green's ability to pay dividends, make certain types of investments, incur additional indebtedness, incur liens and enter into negative pledge agreements and dispose of assets, and which require compliance with financial ratios relating to the maximum ratio of total indebtedness to total asset value, a minimum ratio of EBITDA to fixed charges, a maximum ratio of secured indebtedness to total asset value and a maximum ratio of unsecured indebtedness to unencumbered asset value. The dividend restriction referred to above provides that SL Green will not during any time when a default is continuing, make distributions with respect to SL Green's common stock or other equity interests, except to enable SL Green to continue to qualify as a REIT for Federal income tax purposes. As of December 31, 2015 and 2014, we were in compliance with all such covenants.

Preferred Units

Preferred Units

Through a consolidated subsidiary, we have authorized up to 109,1613.5% Series A Preferred Units of limited partnership interest, or the Greene Series A Preferred Units, with a liquidation preference of $1,000.00 per unit. In August 2015, the Company issued 109,161 Greene Series A Preferred Units in conjunction with an acquisition. The Greene Series A Preferred unitholders receive annual dividends of $35.00 per unit paid on a quarterly basis and dividends are cumulative, subject to certain provisions. The Greene Series A Preferred Units can be redeemed at any time, at the option of the unitholder, either for cash or are convertible on a one-for-one basis, into the Series B Preferred Units of limited partnership interest, or the Greene Series B Preferred Units. The Greene Series B Preferred Units can be converted at any time, at the option of the unitholder, into a number of common stock equal to 6.71348 shares of SL Green common stock for each Greene Series B Preferred Unit. As of December 31, 2015, no Greene Series B Preferred Units have been issued.

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

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

We are required to disclose fair value information with regard to our financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practical to estimate fair value. The FASB guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. We measure and/or disclose the estimated fair value of financial assets and liabilities based on a hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. This hierarchy 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. Our assessment of the significance of the particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

We determine other than temporary impairment in real estate investments and debt and preferred equity investments, including intangibles utilizing cash flow projections that apply, among other things, estimated revenue and expense growth rates, discount rates and capitalization rates, which are classified as Level 3 inputs.

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

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

The following table provides the carrying value and fair value of these financial instruments as of December 31, 2015 and 2014 (in thousands):

	December 31, 2015					December 31, 2014

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Financial Instruments: Derivatives and Hedging

Financial Instruments: Derivatives and Hedging

In the normal course of business, we use a variety of commonly used derivative instruments, such as interest rate swaps, caps, collar and floors, to manage, or hedge interest rate risk. We hedge our exposure to variability in future cash flows for forecasted transactions in addition to anticipated future interest payments on existing debt. We recognize all derivatives on the balance sheets at fair value. Derivatives that are not hedges are adjusted to fair value through earnings. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedge asset, liability, or firm commitment through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative's change in fair value will be immediately recognized in earnings. Reported net income and 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 December 31, 2015, 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 December 31, 2015 based on Level 2 inputs. The notional value is an indication of the extent of our involvement in that instrument at that time, but does not represent exposure to credit, interest rate or market risks.

	Notional Value	Strike Rate	Effective Date	Expiration Date	Balance Sheet Location	Fair Value
Interest Rate Swap	$30,000	2.295%	July 2010	June 2016	Other Liabilities	$	(241	)

Gains and losses on terminated hedges are included in the accumulated other comprehensive loss, and are recognized into earnings over the term of the related senior unsecured notes. As of December 31, 2015 and 2014, 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 $2.0 million and $2.3 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 $0.6 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 instrument that is designated and qualifies as a hedging instrument on the consolidated statements of operations for the years ended December 31, 2015, 2014 and 2013 respectively (in thousands):

Benefit Plans

Benefit Plans

The building employees are covered by multi-employer defined benefit pension plans and post-retirement health and welfare plans. We participate in the Building Service 32BJ, or Union, Pension Plan and Health Plan. The Pension Plan is a multi-employer, non-contributory defined benefit pension plan that was established under the terms of collective bargaining agreements between the Service Employees International Union, Local 32BJ, the Realty Advisory Board on Labor Relations, Inc. and certain other employees. This Pension Plan is administered by a joint board of trustees consisting of union trustees and employer trustees and operates under employer identification number 13-1879376. The Pension Plan year runs from July 1 to June 30. Employers contribute to the Pension Plan at a fixed rate on behalf of each covered employee. Separate actuarial information regarding such pension plans is not made available to the contributing employers by the union administrators or trustees, since the plans do not maintain separate records for each reporting unit. However, on September 28, 2013, September 30, 2014, and September 28, 2015, the actuary certified that for the plan years beginning July 1, 2013, July 1, 2014 and July 1, 2015, respectively, the Pension Plan was in critical status under the Pension Protection Act of 2006. The Pension Plan trustees adopted a rehabilitation plan consistent with this requirement. No surcharges have been paid to the Pension Plan as of December 31, 2015. The Pension Plan received contributions from employers totaling $242.3 million, $226.7 million and $221.9 million, for the plan years beginning July 1, 2012, July 2013 and July 2014, respectively.

The Health Plan was established under the terms of collective bargaining agreements between the Union, the Realty Advisory Board on Labor Relations, Inc. and certain other employers. The Health Plan provides health and other benefits to eligible participants employed in the building service industry who are covered under collective bargaining agreements, or other written agreements, with the Union. The Health Plan is administered by a Board of Trustees with equal representation by the employers and the Union and operates under employer identification number 13-2928869. The Health Plan receives contributions in accordance with collective bargaining agreements or participation agreements. Generally, these agreements provide that the employers contribute to the Health Plan at a fixed rate on behalf of each covered employee. For the Health plan years ended, June 30, 2015, 2014 and 2013, the plan received contributions from employers totaling $1.1 billion, $1.0 billion and $923.5 million, respectively. Our contributions to the Health Plan represent less than 5.0% of total contributions to the plan.

Segment Reporting [Abstract]

Segment Information

Segment Information

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

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

Selected results of operations for the years ended December 31, 2015, 2014 and 2013 and selected asset information as of December 31, 2015 and 2014, 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 debt and preferred equity segment. Interest costs for the debt and preferred equity segment are imputed assuming the portfolio is 100% leveraged by our 2012 revolving credit facility borrowing cost and corporate borrowing cost. We also allocate loan loss reserves, net of recoveries and transaction related costs to the debt and preferred equity segment. We do not allocate marketing, general and administrative expenses to the debt and preferred equity segment, since 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 5, "Debt, 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 the primary beneficiary. The primary beneficiary is the entity that has (i) the power to direct the activities that most significantly impact the entity's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE.

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 is modified to present earnings and other comprehensive income attributed to controlling and noncontrolling interests.

We assess the accounting treatment for each joint venture and debt 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 VIEs, 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, 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 the joint venture. Our joint venture agreements typically contain certain protective rights such as requiring 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

Real estate properties are presented at cost less accumulated depreciation and amortization. Costs directly related to the development or redevelopment of properties are capitalized. Ordinary repairs and maintenance are expensed as incurred; major replacements and betterments, which improve or extend the life of the asset, are capitalized and depreciated over their estimated useful lives.

A property to be disposed of is reported at the lower of its carrying value or its estimated fair value, less its cost to sell. Once an asset is held for sale, depreciation expense is no longer recorded. The Company adopted ASU 2014-08 effective January 1, 2015. As a result, the Company classified 140 Grand Street in White Plains, New York as held for sale as of September 30, 2015, and 131-137 Spring Street as of June 30, 2015 and included the results of operations in continuing operations for all periods presented. Discontinued operations included the results of operations of real estate assets sold or held for sale prior to January 1, 2015. This included 673 First Avenue, which was sold during 2014. See Note 4, "Property Dispositions."

Properties are depreciated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives are as follows:

Category	Term
Building (fee ownership)	40 years
Building improvements	shorter of remaining life of the building or useful life
Building (leasehold interest)	lesser of 40 years or remaining term of the lease
Property under capital lease	remaining lease term
Furniture and fixtures	four to seven years
Tenant improvements	shorter of remaining term of the lease or useful life

Depreciation expense (including amortization of the capital lease asset) amounted to $187.2 million, $184.3 million and $170.0 million for the years ended December 31, 2015, 2014 and 2013, respectively.

On a periodic basis, we assess whether there are any indications that the value of our real estate properties may be other than temporarily impaired or that their carrying value may not be recoverable. A property's value is considered impaired if management's estimate of the aggregate future cash flows (undiscounted 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 either their carrying value or fair value less costs to sell. During the three months ended September 30, 2015, we recorded a $10.0 million charge in connection with the expected sale of one of our properties, which closed in the fourth quarter of 2015. This charge is included in depreciable real estate reserves in the consolidated statements of operations. Prior to the quarter ended September 30, 2015, we do not believe that there were any indicators of impairment at this property. See Note 4, "Property Dispositions." We do not believe that there were any indicators of impairment at any of our consolidated properties at December 31, 2015.

We incur a variety of costs in the development and leasing of our properties. After determination is made to capitalize a cost, it is allocated to the specific component of a project that is benefited. Determination of when a development project is substantially complete and capitalization must cease involves a degree of judgment. The costs of land and building under development include specifically identifiable costs. The capitalized costs include, but are not limited to, pre-construction costs essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. We consider a construction project as substantially completed and held available for occupancy upon the completion of tenant improvements, but no later than one year after major construction activity ceases. We cease capitalization on the portions substantially completed and occupied or held available for occupancy, and capitalize only those costs associated with the portions under construction.

We recognize the assets acquired, liabilities assumed (including contingencies) and any noncontrolling interests in an acquired entity at their fair values on the acquisition date. We expense transaction costs related to the acquisition of certain assets as incurred, which are included in transaction related costs on our consolidated statements of operations. Results of operations of properties acquired are included in the consolidated statements of operations from the date of acquisition.

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

Investment in Unconsolidated Joint Ventures

Investment in Unconsolidated Joint Ventures

We account for our investment in the unconsolidated joint venture under the equity method of accounting in cases where we exercise significant influence, but do not control the entity and are not considered to be the primary beneficiary. We consolidate those 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 we are determined to be the primary beneficiary in a VIE, these participating rights preclude us from consolidating these VIE entities. These investments are recorded initially at cost, as investments in unconsolidated joint ventures, and subsequently adjusted for equity in net income (loss) and cash contributions and distributions. Equity in net income (loss) from unconsolidated joint ventures 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. None of the joint venture debt is recourse to us. See Note 5, "Debt, Preferred Equity and Other Investments."

We assess our investments in unconsolidated joint ventures for recoverability, and if it is determined that a loss in value of the investment is other than temporary, we write down the investment to its fair value. We evaluate our equity investments for impairment based on the joint venture's projected discounted cash flows. We do not believe that the values of any of our equity investments were impaired at December 31, 2015.

We may originate loans for real estate acquisition, development and construction, where we expect to receive some of the residual profit from such projects. When the risk and rewards of these arrangements are essentially the same as an investor or joint venture partner, we account for these arrangements as real estate investments under the equity method of accounting for investments. Otherwise, we account for these arrangements consistent with our loan accounting for our debt and preferred equity investments.

Cash and Cash Equivalents

Cash and Cash Equivalents

We consider all highly liquid investments with maturity of three months or less when purchased to be cash equivalents.

Restricted Cash

Restricted Cash

Restricted cash primarily consists of security deposits held on behalf of our tenants, interest reserves, as well as capital improvement and real estate tax escrows required under certain loan agreements.

Deferred Lease Costs

Deferred Lease Costs

Deferred lease costs consist of fees and direct costs incurred to initiate and renew operating leases and are amortized on a straight-line basis over the related lease term.

Deferred Financing Costs

Deferred Financing Costs

Deferred financing costs represent commitment fees, legal, title and other third party costs associated with obtaining commitments for financing which result in a closing of such financing. These costs are amortized over the terms of the respective agreements. Unamortized deferred financing costs are expensed when the associated debt is refinanced or repaid before maturity. Costs incurred in seeking financing transactions, which do not close, are expensed in the period in which it is determined that the financing will not close.

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 costs, net 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 provided that we have no substantial economic involvement with the buyer.

Interest income on debt and 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 debt and 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 is 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 an adjustment to the interest income over the terms of the related investments using the effective interest method. Fees received in connection with loan commitments are also 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 debt or 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 debt or preferred equity investment at a discount with the intention of foreclosing on the collateral, we do not accrete the discount. For debt investments acquired at a discount for credit quality, the difference between contractual cash flows and expected cash flows at acquisition is not accreted. Anticipated exit fees, the collection of which is expected, are also recognized over the term of the loan as an adjustment to yield.

Debt and 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 debt or preferred equity investment is resumed when such non-accrual debt or 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 the loans individually. When a transaction meets the criteria for 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, original issue discounts, 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 statements of operations. Any fees received at the time of sale or syndication are recognized as part of investment income.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts

We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our tenants to make required payments. If the financial condition of a specific tenant were to deteriorate, resulting in an impairment of its ability to make payments, additional allowances may be required.

Reserve for Possible Credit Losses

Reserve for Possible Credit Losses

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

Where impairment is indicated on an investment that is held to maturity, a valuation allowance is measured based upon the excess of the recorded investment amount over the net fair value of the collateral. Any deficiency between the carrying amount of an asset and the calculated value of the collateral is charged to expense. We continue to assess or adjust our estimates based on circumstances of a loan and the underlying collateral. If additional information reflects increased recovery of our investment, we will adjust our reserves accordingly. There were no loan reserves recorded during years ended December 31, 2015, 2014 and 2013.

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

Rent Expense

Rent Expense

Rent expense is recognized on a straight-line basis over the initial term of the lease. The excess of the rent expense recognized over the amounts contractually due pursuant to the underlying lease is included in the deferred land leases payable on the consolidated balance sheets.

Income Taxes

Income Taxes

ROP is a partnership and, as a result, all income and losses of the partnership are allocated to the partners for inclusion in their respective income tax returns. No provision has been made for income taxes in the consolidated financial statements since such taxes, if any, are the responsibility of the individual partners.

We follow a two-step approach for evaluating uncertain tax positions. Recognition (step one) occurs when an enterprise concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustained upon examination. Measurement (step two) determines the amount of benefit that is more-likely-than-not to be realized upon settlement. Derecognition of a tax position that was previously recognized would occur when a company subsequently determines that a tax position no longer meets the more-likely-than-not threshold of being sustained. The use of a valuation allowance as a substitute for derecognition of tax positions is prohibited.

Shares Contributed by Parent Company

Shares Contributed by Parent Company

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

Exchangeable Debt Instruments

Exchangeable Debt Instruments

The initial proceeds from exchangeable debt that may be settled in cash, including partial cash settlements, must be bifurcated between a liability component and an equity component associated with the embedded conversion option. The objective of the accounting guidance is to require the liability and equity components of exchangeable debt to be separately accounted for in a manner such that the interest expense on the exchangeable debt is not recorded at the stated rate of interest but rather at an effective rate that reflects the issuer's conventional debt borrowing rate at the date of issuance. We calculate the liability component of exchangeable debt based on the present value of the contractual cash flows discounted at our comparable market conventional debt borrowing rate at the date of issuance. The difference between the principal amount and the fair value of the liability component is reported as a discount on the exchangeable debt that is accreted as additional interest expense from the issuance date through the contractual maturity date using the effective interest method. A portion of this additional interest expense may be capitalized to the development and redevelopment balances qualifying for interest capitalization each period. The liability component of the exchangeable debt is reported net of discounts on our consolidated balance sheets. We calculate the equity component of exchangeable debt based on the difference between the initial proceeds received from the issuance of the exchangeable debt and the fair value of the liability component at the issuance date. The equity component is included in additional paid-in-capital, net of issuance costs, on our consolidated balance sheets. We allocate issuance costs for exchangeable debt between the liability and the equity components based on their relative values.

Derivative Instruments

Derivative Instruments

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. Effectiveness is essential for those derivatives that we intend to qualify for hedge accounting. Some derivative instruments are associated with an anticipated transaction. In those cases, hedge effectiveness criteria also require that it be probable that the underlying transaction occurs. Instruments that meet these hedging criteria are formally designated as hedges at the inception of the derivative contract.

To determine the fair values of derivative instruments, we use a variety of methods and assumptions that are based on market conditions and risks existing at each balance sheet date. For the majority of financial instruments including most derivatives, long-term investments and long-term debt, standard market conventions and techniques such as discounted cash flow analysis, option pricing models, replacement cost, and termination cost are used to determine fair value. All methods of assessing fair value result in a general approximation of value, and such value may never actually be realized.

In the normal course of business, we are exposed to the effect of interest rate changes and limit these risks by following established risk management policies and procedures including the use of derivatives. To address exposure to interest rates, derivatives are used primarily to fix the rate on debt based on floating-rate indices and manage the cost of borrowing obligations.

We use a variety of commonly used derivative products that are considered plain vanilla derivatives. These derivatives typically include interest rate swaps, caps, collars and floors. We expressly prohibit the use of unconventional derivative instruments and using derivative instruments for trading or speculative purposes. Further, we have a policy of only entering into contracts with major financial institutions based upon their credit ratings and other factors.

We may employ swaps, forwards or purchased options to hedge qualifying forecasted transactions. Gains and losses related to these transactions are deferred and recognized in net income as interest expense in the same period or periods that the underlying transaction occurs, expires or is otherwise terminated.

Hedges that are reported at fair value and presented on the balance sheet could be characterized as cash flow hedges or fair value hedges. Interest rate caps and collars are examples of cash flow hedges. Cash flow hedges address the risk associated with future cash flows of interest payments. For all hedges held by us and which were deemed to be fully effective in meeting the hedging objectives established by our corporate policy governing interest rate risk management, no net gains or losses were reported in earnings. The changes in fair value of hedge instruments are reflected in accumulated other comprehensive income. For derivative instruments not designated as hedging instruments, the gain or loss resulting from the change in the estimated fair value of the derivative instruments is recognized in current earnings during the period of change.

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, debt and 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 debt and preferred equity investments is located in New York City. See Note 5, "Debt, 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 a space. Although the properties in our real estate portfolio are primarily located in Manhattan, we also have properties located in Brooklyn, Westchester County, Connecticut and New Jersey. The tenants located in our buildings operate in various industries.

Reclassification

Reclassification

Certain prior year balances have been reclassified to conform to our current year presentation primarily in order to include the transfer of two properties, SL Green's tenancy in common interest in a fee interest and one entity that held debt investments and financing receivables in 2015.

Accounting Standards Updates

Accounting Standards Updates

In February 2016, the Financial Accounting Standards Board, or FASB, issued guidance that amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted improvements to lessor accounting (Accounting Standards Update, or ASU, No. 2016-02). The guidance requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The guidance will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting this new accounting standard on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01 (ASC 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. The guidance requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and to record changes in instruments-specific credit risk for financial liabilities measured under the fair value option in other comprehensive income. The guidance is effective for fiscal years beginning after December 15, 2017, and for interim periods therein. The Company is currently evaluating the impact of adopting this new accounting standard on the Company’s consolidated financial statements.

In September 2015, the FASB issued final guidance to simplify the measurement-period adjustments in business combinations (ASU No. 2015-16). The guidance eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments in the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previously periods if the accounting had been completed at the acquisition date. The guidance is effective for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. Early adoption of the guidance is permitted. The Company adopted the guidance during the third quarter of 2015.

In April 2015, the FASB issued final guidance to simplify the presentation of debt issuance costs by requiring debt issuance costs to be presented as a deduction from the corresponding debt liability (ASU No. 2015-03). The guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. The guidance is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption of the guidance is permitted. Upon adoption, an entity must apply the new guidance retrospectively for all prior periods presented in the financial statements. The Company adopted the guidance effective January 1, 2016 and the guidance did not have a material impact on our consolidated financial statements.

In February 2015, the FASB, issued new guidance that amends the current consolidation guidance, including introducing a separate consolidation analysis specific to limited partnerships and other similar entities (ASU No. 2015-02). Under this analysis, limited partnerships and other similar entities will be considered a VIE unless the limited partners hold substantive kick-out rights or participating rights.The guidance is effective for annual and interim periods beginning after December 15, 2015. Early adoption of this guidance is permitted. The Company adopted the guidance effective January 1, 2016 and the guidance did not have a material impact on our consolidated financial statements.

In June 2014, the FASB issued final guidance that requires repurchase-to-maturity transactions to be accounted for as secured borrowings as if the transferor retains effective control, even though the transferred financial assets are not returned to the transferor at settlement and also eliminates existing guidance for repurchase financings (ASU No. 2014-11). New disclosures are required for (1) certain transactions accounted for as secured borrowings and (2) transfers accounted for as sales when the transferor also retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. The guidance was effective for the first interim or annual period beginning after December 15, 2014, except for the disclosures related to transactions accounted for as secured borrowings, which are effective for periods beginning after March 15, 2015. Early adoption of this guidance is prohibited. The Company adopted the standard beginning in the third quarter of 2015 as a result of the transfer of one entity that held debt investments and financing receivables during the third quarter of 2015. The adoption of this guidance did not have a material impact on our consolidated financial statements.

In May 2014, the FASB issued a new comprehensive revenue recognition guidance which requires us to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods and services (ASU No. 2014-09). The guidance also requires enhanced disclosures to help users of financial statements better understand the nature, amount, timing, and uncertainty of revenue that is recognized. The guidance is effective for annual and interim periods beginning after December 15, 2016 and early adoption is not permitted. In July 2015, the FASB voted to defer by one year the effective date of ASU No. 2014-09 for both public and nonpublic entities and give both public and private companies the option to early adopt using the original effective date. The new guidance can be applied either retrospectively to each prior reporting period presented, or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements.

In April 2014, the FASB issued new guidance on reporting discontinued operations which raises the threshold for disposals to qualify as discontinued operations (ASU No. 2014-08). 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 was 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 this guidance was permitted. The Company adopted the standard beginning in the first quarter of 2015. The adoption of this guidance changed the presentation of discontinued operations for all properties held for sale and/or disposed of subsequent to January 1, 2015.

Fair Value Measurements

Fair Value Measurements

We are required to disclose fair value information with regard to our financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practical to estimate fair value. The FASB guidance defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. We measure and/or disclose the estimated fair value of financial assets and liabilities based on a hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. This hierarchy 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. Our assessment of the significance of the particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

We determine other than temporary impairment in real estate investments and debt and preferred equity investments, including intangibles utilizing cash flow projections that apply, among other things, estimated revenue and expense growth rates, discount rates and capitalization rates, which are classified as Level 3 inputs.

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

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