Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION KBS Real Estate Investment Trust, Inc. (the “Company”) was formed on June 13, 2005 as a Maryland corporation and has elected to be taxed as a real estate investment trust (“REIT”). Substantially all of the Company’s assets are held by, and the Company conducts substantially all of its operations through, KBS Limited Partnership, a Delaware limited partnership (the “Operating Partnership”), and its subsidiaries. The Company is the sole general partner of and directly owns a 99% partnership interest in the Operating Partnership. The Company’s wholly owned subsidiary, KBS REIT Holdings LLC, a Delaware limited liability company (“KBS REIT Holdings”), owns the remaining 1% partnership interest in the Operating Partnership and is its sole limited partner. The Company invested in a diverse portfolio of real estate and real estate-related investments. As of September 30, 2015 , the Company owned or, with respect to a limited number of properties, held a leasehold interest in, 391 real estate properties (of which three properties were held for sale), including the GKK Properties (defined below). In addition, as of September 30, 2015 , the Company owned four real estate loans receivable and a participation interest with respect to a real estate joint venture. On September 1, 2011, the Company, through indirect wholly owned subsidiaries (collectively, “KBS”), entered into a Collateral Transfer and Settlement Agreement (the “Settlement Agreement”) with, among other parties, GKK Stars Acquisition LLC (“GKK Stars”), the wholly owned subsidiary of Gramercy Property Trust, Inc. (“Gramercy”) that indirectly owned the Gramercy real estate portfolio, to effect the orderly transfer of certain assets and liabilities of the Gramercy real estate portfolio to KBS in satisfaction of certain debt obligations under a mezzanine loan owed by wholly owned subsidiaries of Gramercy to KBS (the “GKK Mezzanine Loan”). The Settlement Agreement resulted in the transfer of the equity interests in certain subsidiaries of Gramercy (the “Equity Interests”) that indirectly owned or, with respect to a limited number of properties, held a leasehold interest in, 867 properties (the “GKK Properties”), consisting of 576 bank branch properties and 291 office buildings, operations centers and other properties. As of December 15, 2011, GKK Stars had transferred all of the Equity Interests to the Company, giving the Company title to or, with respect to a limited number of GKK Properties, a leasehold interest in, 867 GKK Properties as of that date. Subject to certain restrictions and limitations, the business of the Company is managed by KBS Capital Advisors LLC (the “Advisor”), an affiliate of the Company, pursuant to an advisory agreement with the Company (as amended, the “Advisory Agreement”) in effect through November 8, 2015. The Advisory Agreement may be renewed for an unlimited number of one -year periods upon the mutual consent of the Advisor and the Company. Either party may terminate the Advisory Agreement upon 60 days written notice. The Advisor owns 20,000 shares of the Company’s common stock. Upon commencing its initial public offering (the “Offering”), the Company retained KBS Capital Markets Group LLC (the “Dealer Manager”), an affiliate of the Advisor, to serve as the dealer manager of the Offering pursuant to a dealer manager agreement dated January 27, 2006 (the “Dealer Manager Agreement”). The Company ceased offering shares of common stock in its primary offering on May 30, 2008. The Company terminated its dividend reinvestment plan effective April 10, 2012. The Company sold 171,109,494 shares of common stock in its primary offering for gross offering proceeds of $1.7 billion . The Company sold 28,306,086 shares of common stock under its dividend reinvestment plan for gross offering proceeds of $233.7 million . As of September 30, 2015 , the Company had redeemed 12,598,405 of the shares sold in the Offering for $90.0 million . Asset Management Services Agreement Related to the GKK Properties On December 19, 2013, the Company, through an indirect wholly owned subsidiary (“KBS Acquisition Sub”), entered into an amended and restated asset management services agreement (the “Amended Services Agreement”) with GKK Realty Advisors LLC (the “Property Manager”), an affiliate of Gramercy, with respect to the GKK Properties. The effective date of the Amended Services Agreement was December 1, 2013. Pursuant to the Amended Services Agreement, the Property Manager agreed to provide, among other services: standard asset management services, assistance related to dispositions, accounting services and budgeting and business plans for the GKK Properties (the “Services”). The Property Manager is not affiliated with the Company or KBS Acquisition Sub. As compensation for the Services, the Company agreed to pay the Property Manager: (i) an annual fee of $7.5 million plus all GKK Property-related expenses incurred by the Property Manager, (ii) subject to certain terms and conditions in the Amended Services Agreement, a profit participation interest based on a percentage (ranging from 10% to 30% ) of the amount by which the gross fair market value or gross sales price of certain identified portfolios of GKK Properties exceeds the sum of (a) an agreed-upon baseline value for such GKK Property portfolios plus (b) new capital expended to increase the value of GKK Properties within the portfolios and expenditures made to pay for tenant improvements and leasing commissions related to these GKK Properties as of the measurement date, and (iii) a monthly construction oversight fee equal to a percentage of construction costs for certain construction projects at the GKK Properties overseen by the Property Manager. The Amended Services Agreement will terminate on December 31, 2016, with a one -year extension option at the Company’s option, subject to certain terms and conditions contained in the Amended Services Agreement. The Amended Services Agreement supersedes and replaces all prior agreements related to the Services among the Company and its affiliates and the Property Manager and its affiliates.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES There have been no significant changes to the Company’s accounting policies since it filed its audited financial statements in its Annual Report on Form 10-K for the year ended December 31, 2014 . For further information about the Company’s accounting policies, refer to the Company’s consolidated financial statements and notes thereto for the year ended December 31, 2014 included in the Company’s Annual Report on Form 10-K filed with the SEC. Principles of Consolidation and Basis of Presentation The accompanying unaudited consolidated financial statements and condensed notes thereto have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the SEC, including the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for audited financial statements. In the opinion of management, the financial statements for the unaudited interim periods presented include all adjustments, which are of a normal and recurring nature, necessary for a fair and consistent presentation of the results for such periods. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 . The consolidated financial statements include the accounts of the Company, KBS REIT Holdings, the Operating Partnership and their direct and indirect wholly owned subsidiaries. All significant intercompany balances and transactions are eliminated in consolidation. Use of Estimates The preparation of the consolidated financial statements and condensed notes thereto in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates. Reclassifications Certain amounts in the Company’s prior period consolidated financial statements have been reclassified to conform to the current period presentation. These reclassifications have not changed the results of operations of prior periods. During the nine months ended September 30, 2015 , the Company sold seven properties (of which five were GKK Properties), two of which were held for sale as of December 31, 2014. As a result, certain assets and liabilities were reclassified to held for sale on the consolidated balance sheets for all periods presented. Operating results of properties that were classified as held for sale in financial statements prior to January 1, 2014 will remain in discontinued operations on the Company’s consolidated statements of operations. Operating results of properties that were disposed of or classified as held for sale in the ordinary course of business subsequent to January 1, 2014 that had not been classified as held for sale in financial statements issued for the reporting periods prior to January 1, 2014 are included in continuing operations on the Company’s consolidated statements of operations. Per Share Data Basic net income (loss) per share of common stock is calculated by dividing net income (loss) by the weighted-average number of shares of common stock issued and outstanding during such period. Diluted net income (loss) per share of common stock equals basic net income (loss) per share of common stock as there were no potentially dilutive securities outstanding during the three and nine months ended September 30, 2015 and 2014 , respectively. Distributions declared per share of common stock were $0.025 and $0.075 for the three and nine months ended September 30, 2015 , respectively. On March 6, 2015, the Company’s board of directors declared a distribution in the amount of $0.025 per share of common stock to stockholders of record as of the close of business on March 20, 2015. On May 13, 2015, the Company’s board of directors declared a distribution in the amount of $0.025 per share of common stock to stockholders of record as of the close of business on June 19, 2015. On August 11, 2015, the Company’s board of directors declared a distribution in the amount of $0.025 per share of common stock to stockholders of record as of the close of business on September 18, 2015. Distributions declared per share of common stock were $0.025 and $0.025 for the three and nine months ended September 30, 2014 , respectively. On September 30, 2014, the Company's board of directors declared a distribution in the amount of $0.025 per share of common stock to stockholders of record as of the close of business on September 30, 2014. Segments The Company’s segments are based on the Company’s method of internal reporting, which classifies its operations by investment type: (i) real estate, (ii) real estate-related and (iii) commercial properties primarily leased to financial institutions received under the Settlement Agreement, the GKK Properties. For financial data by segment, see Note 12, “Segment Information.” Recently Issued Accounting Standards Update In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU No. 2014-09”). ASU No. 2014-09 requires an entity to recognize the revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. ASU No. 2014-09 supersedes the revenue requirements in Revenue Recognition (Topic 605) and most industry-specific guidance throughout the Industry Topics of the Codification. ASU No. 2014-09 does not apply to lease contracts within the scope of Leases (Topic 840). ASU No. 2014-09 was to be effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and is to be applied retrospectively, with early application not permitted. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date (“ASU No. 2015-14”), which defers the effective date of ASU No. 2014-09 by one year. Early adoption is permitted but not before the original effective date. The Company is still evaluating the impact of adopting ASU No. 2014-09 on its financial statements, but does not expect the adoption of ASU No. 2014-09 to have a material impact on its financial statements. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements (Subtopic 205-40) , Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU No. 2014-15”). The amendments in ASU No. 2014-15 require management to evaluate, for each annual and interim reporting period, whether there are conditions or events, considered in the aggregate, that raise substantial doubt about an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or are available to be issued when applicable) and, if so, provide related disclosures. ASU No. 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early adoption is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. The Company does not expect the adoption of ASU No. 2014-15 to have a significant impact on its financial statements. In January 2015, the FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20), Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items (“ASU No. 2015-01”). The amendments in ASU No. 2015-01 eliminate from GAAP the concept of extraordinary items. Although the amendments will eliminate the requirements in Subtopic 225-20 for reporting entities to consider whether an underlying event or transaction is extraordinary, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. ASU No. 2015-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect the adoption of ASU No. 2015-01 to have a significant impact on its financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30), Simplifying the Presentation of Debt Issuance Costs (“ASU No. 2015-03”). The amendments in ASU No. 2015-03 require debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. ASU No. 2015-03 is limited to the presentation of debt issuance costs and does not affect the recognition and measurement of debt issuance costs. Given the absence of authoritative guidance within ASU No. 2015-03 for debt issuance costs related to line-of-credit arrangements, in August 2015, the FASB issued ASU No. 2015-15, Interest - Imputation of Interest (Subtopic 835-30), Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (“ASU No. 2015-15”), which clarifies ASU No. 2015-03 by stating that the staff of the SEC would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU No. 2015-03 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015 and is to be applied retrospectively. Early adoption is permitted for financial statements that have not been previously issued. The adoption of ASU No. 2015-03 would change the presentation of debt issuance costs as the Company presents debt issuance costs as deferred financing costs, prepaid expenses and other assets on the accompanying consolidated balance sheets. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments (“ASU No. 2015-16”). The amendments in ASU No. 2015-16 require that in a business combination, an acquirer recognizes adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. ASU No. 2015-16 is effective for annual periods beginning after December 15, 2015, and interim periods within those fiscal years and is to be applied prospectively. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect the adoption of ASU No. 2015-16 to have a significant impact on its financial statements.

These properties are located in 31 states and include office properties, industrial properties and bank branch properties. Included in the Company’s portfolio of real estate held for investment was 5.2 million rentable square feet related to the GKK Properties held for investment, which were 80% occupied as of September 30, 2015 . The following table summarizes the Company’s investments in real estate as of September 30, 2015 and December 31, 2014 (in thousands): Land Buildings and Improvements Tenant Origination and Absorption Costs Total Real Estate Held for Investment As of September 30, 2015: Office $ 63,146 $ 361,643 $ 1,270 $ 426,059 Industrial 16,787 83,475 2,244 102,506 GKK Properties 171,473 303,044 65,803 540,320 Real estate held for investment, at cost and net of impairment charges 251,406 748,162 69,317 1,068,885 Accumulated depreciation/amortization — (130,863 ) (34,831 ) (165,694 ) Real estate held for investment, net $ 251,406 $ 617,299 $ 34,486 $ 903,191 As of December 31, 2014: Office $ 68,178 $ 401,083 $ 1,825 $ 471,086 Industrial 16,787 80,565 3,137 100,489 GKK Properties 169,671 306,301 66,858 542,830 Real estate held for investment, at cost and net of impairment charges 254,636 787,949 71,820 1,114,405 Accumulated depreciation/amortization — (137,309 ) (30,481 ) (167,790 ) Real estate held for investment, net $ 254,636 $ 650,640 $ 41,339 $ 946,615 Operating Leases The Company’s real estate assets are leased to tenants under operating leases for which the terms and expirations vary. As of September 30, 2015 , the Company’s leases, including the GKK Properties held for investment and excluding options to extend, had remaining terms of up to 14.8 years with a weighted-average remaining term of 4.5 years. As of September 30, 2015 , leases related to the GKK Properties, excluding options to extend, had remaining terms of up to 11.4 years with a weighted-average remaining term of 4.5 years. Some of the Company’s leases have provisions to extend the term of the leases, options for early termination for all or a part of the leased premises after paying a specified penalty, rights of first refusal to purchase the property at competitive market rates, and other terms and conditions as negotiated. Additionally, the Company assumed several leases related to the GKK Properties which contain shedding rights provisions. As of September 30, 2015 , these shedding rights totaled approximately 33,000 square feet and can be exercised at various dates during the remainder of 2015 through 2016. Subsequent to September 30, 2015 , a tenant exercised its rights to shed 30,000 square feet from its leased premises. The Company retains substantially all of the risks and benefits of ownership of the real estate assets leased to tenants. Generally, upon the execution of a lease, the Company requires a security deposit from the tenant in the form of a cash deposit and/or a letter of credit. The amount required as a security deposit varies depending upon the terms of the respective lease and the creditworthiness of the tenant, but generally is not a significant amount. Therefore, exposure to credit risk exists to the extent that a receivable from a tenant exceeds the amount of its security deposit. Security deposits received in cash related to tenant leases are included in other liabilities in the accompanying consolidated balance sheets and totaled $3.0 million and $3.0 million as of September 30, 2015 and December 31, 2014 , respectively. During the nine months ended September 30, 2015 and 2014 , the Company recognized deferred rent from tenants of $1.8 million and $2.5 million , respectively. These excess amounts for the nine months ended September 30, 2015 and 2014 were net of $1.0 million and $1.0 million of lease incentive amortization, respectively. As of September 30, 2015 and December 31, 2014 , the cumulative deferred rent balance was $29.3 million and $27.3 million , respectively, and is included in rents and other receivables on the accompanying balance sheets. The cumulative deferred rent balance included $6.0 million and $5.7 million of unamortized lease incentives as of September 30, 2015 and December 31, 2014 , respectively. The Company records property operating expense reimbursements due from tenants for common area maintenance, real estate taxes and other recoverable costs in the period the related expenses are incurred. The future minimum rental income from the Company’s properties under non-cancelable operating leases, including leases subject to shedding rights and excluding options to extend, as of September 30, 2015 for the years ending December 31 is as follows (in thousands): October 1, 2015 through December 31, 2015 $ 27,701 2016 112,821 2017 104,348 2018 91,639 2019 77,646 Thereafter 206,657 $ 620,812 As of September 30, 2015 , the Company’s highest tenant industry concentration (greater than 10% of annualized base rent) was as follows: Industry Number of Tenants Annualized (1) (in thousands) Percentage of Annualized Base Rent Finance 73 $ 54,260 47.6 % _____________________ (1) Annualized base rent represents annualized contractual base rental income as of September 30, 2015 , adjusted to straight-line any contractual tenant concessions (including free rent), rent increases and rent decreases from the lease's inception through the balance of the lease term. As of September 30, 2015 , no other tenant industries accounted for more than 10% of the Company’s annualized base rent. The Company currently has over 300 tenants over a diverse range of industries and geographical regions. As of September 30, 2015 and December 31, 2014 , the Company had a bad debt expense reserve of $0.9 million and $1.1 million , respectively. The Company’s bad debt expense reserve as of September 30, 2015 and December 31, 2014 included $0.6 million and $1.0 million related to the GKK Properties, respectively. During the nine months ended September 30, 2015 and 2014 , the Company recorded bad debt recovery related to its tenant receivables of $38,000 and $1.4 million , respectively. As of September 30, 2015 , the Company had a concentration of credit risk related to leases with the following tenant that represented more than 10% of the Company’s annualized base rent: Annualized Base Rent Statistics Tenant Property Tenant Industry Rentable Square Feet % of Portfolio Rentable Square Feet Annualized Base Rent (1) (in thousands) % of Portfolio Annualized Base Rent Annualized Base Rent per Square Foot Lease Expirations Bank of America, N.A.

Bank of America Corporation is the guarantor of various leases that its subsidiary, Bank of America, N.A., has with the Company. The condensed consolidated financial information of Bank of America Corporation has been included herein because of the significant credit concentration the Company has with this guarantor. Bank of America Corporation currently files its financial statements in reports filed with the SEC, and the following unaudited summary financial data regarding Bank of America Corporation is taken from its previously filed public reports. For more detailed financial information regarding Bank of America Corporation, please refer to its financial statements, which are publicly available with the SEC at http:// www.sec.gov. Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Consolidated Statements of Income (in millions) Total revenue, net of interest expense $ 20,682 $ 21,209 $ 64,001 $ 65,522 Income before income taxes 6,069 431 18,330 2,545 Net income (loss) 4,508 (232 ) 13,185 1,783 As of September 30, 2015 December 31, 2014 Consolidated Balance Sheets (in millions) Total assets $ 2,153,006 $ 2,104,534 Total liabilities 1,897,101 1,861,063 Total stockholders’ equity 255,905 243,471 No other tenant represented more than 10% of the Company’s annualized base rent. Geographic Concentration Risk As of September 30, 2015 , the Company’s net investments in real estate in Virginia represented 11.2% of the Company’s total assets. As a result, the geographic concentration of the Company’s portfolio makes it particularly susceptible to adverse economic developments in Virginia’s real estate market. Any adverse economic or real estate developments in this market, such as business layoffs or downsizing, industry slowdowns, relocations of businesses, changing demographics and other factors, or any decrease in demand for office or bank branch space resulting from the local business climate, could adversely affect the Company’s operating results. Impairment of Real Estate During the three and nine months ended September 30, 2015 , the Company recorded non-cash impairment charges of $34.9 million with respect to 12 properties (including nine GKK Properties) to write-down the carrying values of certain of its real estate investments to their estimated fair values. The facts and circumstances leading to the impairments on the Company’s real estate held for investment are as follows: Woodfield Preserve Office Center The Company recognized an impairment charge during the three and nine months ended September 30, 2015 of $18.1 million to reduce the carrying value of the Company’s investment in Woodfield Preserve Office Center, an office property located in Schaumburg, Illinois, due to a decrease in projected cash flow projections. Chicago’s northwest suburb office rental market was heavily affected by the 2008-2009 recession; however, the outlook was optimistic that the market would recover to levels seen prior to the recession. Although the general market has seen positive net absorption, rental rates have remained low while lease concessions remain high resulting in lower projected revenue growth and cash flow projections. The market conditions in Schaumburg, Illinois have also resulted in a lack of interest from investors. Tysons Dulles Plaza The Company recognized an impairment charge during the three and nine months ended September 30, 2015 of $15.7 million to reduce the carrying value of Tysons Dulles Plaza, an office property located in McLean, Virginia, to its estimated fair value. The Company revised its cash flow projections primarily for longer estimated lease up periods as a result of the continued lack of demand in the McLean office rental market. While the market has seen slight increases in rental rates, lease concessions have not declined as previously expected. The Company also revised its cash flow projections to account for higher projected capital costs for tenant improvements, general building upgrades, and deferred maintenance costs needed to position the property competitively with other properties in the area, to address certain maintenance issues and to attract additional tenants. The lack of sales activity in McLean, Virginia has also resulted in higher capitalization rates. Other Properties The Company recognized impairment charges during the three and nine months ended September 30, 2015 of $1.1 million related to ten other properties, including nine GKK Properties. No impairment charge related to any individual property was greater than $250,000 . These impairments generally resulted from changes in the projected hold periods or changes in leasing projections including longer estimated lease-up periods and lower projected rental rates, thus decreasing the projected cash flows the properties would generate. Prior Period Impairments During the three and nine months ended September 30, 2014 , the Company recorded impairment charges of $7.7 million with respect to three properties (including one GKK Property) and $9.9 million with respect to five properties (including one GKK Property), respectively. Included in the Company’s impairment charges during the three and nine months ended September 30, 2014 was a $7.2 million impairment charge to reduce the carrying value of the Company’s investment in Tysons Dulles Plaza to its estimated fair value due to a change in cash flow projections. The Company revised its cash flow projections for Tysons Dulles Plaza primarily because of a continued lag in demand in the Washington D.C. office rental market, resulting in ongoing leasing challenges and lower projected revenue growth. The Company also revised its cash flow projections to account for higher projected capital costs for tenant improvements and general building upgrades needed to attract additional tenants.

Foreclosed Real Estate Held for Sale [Abstract]
FORECLOSED REAL ESTATE HELD FOR SALE	FORECLOSED REAL ESTATE HELD FOR SALE In 2006 and 2007, the Company originally made three debt investments (collectively, the “Tribeca Loans”) related to the conversion of an eight-story loft building into a 10-story condominium building with 62 units (the “Tribeca Building”) located at 415 Greenwich Street in New York, New York. On February 19, 2010, the borrowers under the Tribeca Loans defaulted and the Company foreclosed on the Tribeca Building by exercising its right to accept 100% of the ownership interest of the borrowers. The Company acquired the remaining unsold condominium units of the Tribeca Building (the residential, retail and parking space condominium units transferred to the Company are, collectively, the “Units” and, individually, each is a “Unit”) and assumed the project liabilities. The Company recorded the Tribeca Building at fair value using a discounted cash flow valuation model based on the net realizable value (expected sales price less estimated costs to sell the unsold Units) of the real estate. As of December 31, 2014 , the Company’s investment in the Tribeca Building consisted of two Units with a carrying value of $12.0 million and is presented as foreclosed real estate held for sale on the consolidated balance sheet. During the nine months ended September 30, 2015 , the Company sold the remaining two Units and recognized a gain on sale of $2.5 million (which gain on sale has been reduced by disposition fees to the Advisor of $0.2 million related to these two Units) and recorded expenses of $0.3 million related to foreclosed real estate held for sale. The Company did not sell any condominium units of the Tribeca Building during the nine months ended September 30, 2014 and recorded expenses of $1.1 million related to foreclosed real estate held for sale.

A breach of the financial covenants in these documents may result in the lender imposing additional restrictions on the Company’s operations, such as restrictions on the Company’s ability to incur additional debt, or may allow the lender to impose “cash traps” with respect to cash flow from the property securing the loan. In addition, such a breach may constitute an event of default and the lender could require the Company to repay the debt immediately. If the Company fails to make such repayment in a timely manner, the lender may be entitled to take possession of any property securing the loan. As of September 30, 2015 , the Company was in compliance with these debt covenants.

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	9 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES	FAIR VALUE DISCLOSURES Under GAAP, the Company is required to measure certain financial instruments at fair value on a recurring basis. In addition, the Company is required to measure other financial instruments and balances at fair value on a non-recurring basis (e.g., carrying value of impaired real estate loans receivable and long-lived assets). Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The GAAP fair value framework uses a three-tiered approach. Fair value measurements are classified and disclosed in one of the following three categories: • Level 1: unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities; • Level 2: quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and • Level 3: prices or valuation techniques where little or no market data is available that requires inputs that are both significant to the fair value measurement and unobservable. The fair value for certain financial instruments is derived using a combination of market quotes, pricing models and other valuation techniques that involve significant management judgment. The price transparency of financial instruments is a key determinant of the degree of judgment involved in determining the fair value of the Company’s financial instruments. Financial instruments for which actively quoted prices or pricing parameters are available and for which markets contain orderly transactions will generally have a higher degree of price transparency than financial instruments for which markets are inactive or consist of non-orderly trades. The Company evaluates several factors when determining if a market is inactive or when market transactions are not orderly. The following is a summary of the methods and assumptions used by management in estimating the fair value of each class of assets and liabilities for which it is practicable to estimate the fair value: Cash and cash equivalents, restricted cash, rent and other receivables, and accounts payable and accrued liabilities: These balances approximate their fair values due to the short maturities of these items. Real estate loans receivable: These instruments are presented in the accompanying consolidated balance sheets at their amortized cost net of recorded loan loss reserves and not at fair value. The fair values of real estate loans receivable were estimated using an internal valuation model that considered the expected cash flows for the loans, underlying collateral values (for collateral-dependent loans) and estimated yield requirements of institutional investors for loans with similar characteristics, including remaining loan term, loan-to-value, type of collateral and other credit enhancements. The Company classifies these inputs as Level 3 inputs. Notes payable: The fair values of the Company’s notes payable are estimated using a discounted cash flow analysis based on management’s estimates of current market interest rates for instruments with similar characteristics, including remaining loan term, loan-to-value ratio, type of collateral and other credit enhancements. Additionally, when determining the fair value of a liability in circumstances in which a quoted price in an active market for an identical liability is not available, the Company measures fair value using (i) a valuation technique that uses the quoted price of the identical liability when traded as an asset or quoted prices for similar liabilities when traded as assets or (ii) another valuation technique that is consistent with the principles of fair value measurement, such as the income approach or the market approach. The Company classifies these inputs as Level 3 inputs. The following were the face values, carrying amounts and fair values of the Company’s real estate loans receivable and notes payable as of September 30, 2015 and December 31, 2014 , which carrying amounts generally do not approximate the fair values (in thousands): September 30, 2015 December 31, 2014 Face Value Carrying Amount Fair Value Face Value Carrying Amount Fair Value Financial assets: Real estate loans receivable (1) $ 35,842 $ 27,044 $ 24,526 $ 35,966 $ 28,922 $ 25,818 Financial liabilities: Notes payable $ 521,698 $ 518,242 $ 547,075 $ 664,628 $ 658,098 $ 688,374 _____________________ (1) Carrying amount of real estate loans receivable includes loan loss reserves. Disclosure of the fair values of financial instruments is based on pertinent information available to the Company as of the period end and requires a significant amount of judgment. The actual value of these investments could be materially different from the Company’s estimate of value.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS The Company has entered into an Advisory Agreement with the Advisor, which entitles the Advisor to specified fees for the management and disposition of investments, among other services, as well as to reimbursement for certain costs incurred by the Advisor in providing services to the Company. In addition, the Advisor is entitled to certain other fees, including an incentive fee upon achieving certain performance goals, as detailed in the Advisory Agreement. The Company has also entered into a fee reimbursement agreement (the “AIP Reimbursement Agreement”) with the Dealer Manager pursuant to which the Company agreed to reimburse the Dealer Manager for certain fees and expenses it incurs for administering the Company’s participation in the DTCC Alternative Investment Product Platform with respect to certain accounts of the Company’s investors serviced through the platform. The Advisor also serves, and the Dealer Manager also serves or served, as the advisor and dealer manager, respectively, for KBS Real Estate Investment Trust II, Inc., KBS Real Estate Investment Trust III, Inc., KBS Strategic Opportunity REIT, Inc., KBS Legacy Partners Apartment REIT, Inc., KBS Strategic Opportunity REIT II, Inc. and KBS Growth & Income REIT, Inc. On January 6, 2014, the Company, together with KBS Real Estate Investment Trust II, Inc., KBS Real Estate Investment Trust III, Inc., KBS Strategic Opportunity REIT, Inc., KBS Legacy Partners Apartment REIT, Inc., KBS Strategic Opportunity REIT II, Inc., the Dealer Manager, the Advisor and other KBS-affiliated entities, entered into an errors and omissions and directors and officers liability insurance program where the lower tiers of such insurance coverage are shared. The cost of these lower tiers is allocated by the Advisor and its insurance broker among each of the various entities covered by the program, and is billed directly to each entity. The allocation of these shared coverage costs is proportionate to the pricing by the insurance marketplace for the first tiers of directors and officers liability coverage purchased individually by each REIT. The Advisor’s and the Dealer Manager’s portion of the shared lower tiers’ cost is proportionate to the respective entities’ prior cost for the errors and omissions insurance. In June 2015, KBS Growth & Income REIT, Inc. was added to the insurance program at terms similar to those described above. During the nine months ended September 30, 2015 and 2014 , no other business transactions occurred between the Company and the other KBS-sponsored programs. On May 18, 2012, KBS Strategic Opportunity REIT, Inc. made an $8.0 million investment in a joint venture in which the Company indirectly owns a participation interest through another joint venture investment. Pursuant to the terms of the Advisory Agreement and the AIP Reimbursement Agreement, summarized below are the related-party costs incurred by the Company for the three and nine months ended September 30, 2015 and 2014 , respectively, and any related amounts payable as of September 30, 2015 and December 31, 2014 (in thousands): Incurred Payable Three Months Ended September 30, Nine Months Ended September 30, September 30, December 31, 2015 2014 2015 2014 2015 2014 Expensed Asset management fees (1) $ 2,386 $ 2,473 $ 7,152 $ 7,520 $ — $ — Reimbursement of operating expenses (2) 60 53 159 156 4 45 Disposition fees (3) — — 2,253 775 — 399 $ 2,446 $ 2,526 $ 9,564 $ 8,451 $ 4 $ 444 _____________________ (1) Amounts include asset management fees from discontinued operations totaling $17,000 for the nine months ended September 30, 2014 . (2) The Advisor may seek reimbursement for certain employee costs under the Advisory Agreement. The Company reimburses the Advisor for the Company’s allocable portion of the salaries, benefits and overhead of internal audit department personnel providing services to the Company. These amounts totaled $51,000 and $53,000 for the three months ended September 30, 2015 and 2014 , respectively, and $0.1 million and $0.2 million for the nine months ended September 30, 2015 and 2014 , respectively. These were the only type of employee costs reimbursed under the Advisory Agreement for the three and nine months ended September 30, 2015 and 2014 . The Company will not reimburse for employee costs in connection with services for which the Advisor earns disposition fees (other than reimbursement of travel and communication expenses) or for the salaries or benefits the Advisor or its affiliates may pay to the Company’s executive officers. (3) Disposition fees with respect to real estate sold are included in the gain on sales of real estate in the accompanying consolidated statements of operations. Advisory Agreement Amendment On January 15, 2015, the Company and the Advisor entered into an amendment to the Advisory Agreement to amend certain terms related to the disposition fee payable to the Advisor by the Company. In accordance with the Advisory Agreement, for substantial assistance in connection with the sale of properties, loans or other investments as determined by the conflicts committee of the Company’s board of directors, the Company pays the Advisor or its affiliates a disposition fee of 1% of the contract sales price of the properties, loans or other investments sold. However, in no event may the total commissions (including such disposition fees) paid to the Advisor, its affiliates and unaffiliated third parties exceed 6% of the contract sales price of the property, loan or other investment sold or exceed a competitive real estate commission. Pursuant to the amendment, the disposition fee related to the sales of GKK Properties has been modified to provide that the conflicts committee will determine in its sole discretion the amount of the disposition fee related to the sale of GKK Properties upon the terms set forth below, which disposition fee may be an amount not to exceed 1% of the contract sales price, which maximum amount is consistent with the fixed percentage applicable to the sales of other properties, loans and other investments under the Advisory Agreement. The amendment provides that with respect to sales of the GKK Properties, and provided that the conflicts committee determines that the Advisor has provided a substantial amount of services in connection with the sale of each GKK Property for which the payment of a disposition fee is requested by the Advisor, then: (a) With respect to portfolio or single asset sales of GKK Properties designated by the conflicts committee in its sole discretion at or about the time of the sale, the Company will pay the Advisor a fee in an amount not to exceed 1% of the contract sales price and subject to other limitations and conditions set forth in the Advisory Agreement, as determined by the conflicts committee in its sole discretion, which fee will be payable upon the respective closing; and (b) With respect to sales of all other GKK Properties for which a disposition fee has not yet been paid, if, upon the sale of the final GKK Property, the conflicts committee determines in its sole discretion that the Company has recovered its entire investment related to the GKK Mezzanine Loan and the GKK Properties subsequent to the Settlement Agreement, after taking into consideration the net cash flow received by the Company from the investment, whether in the form of (i) net proceeds from the sales or other dispositions or transfers of the GKK Properties, (ii) the net cash flow related to the GKK Mezzanine Loan, (iii) the net cash flow related to the GKK Properties subsequent to the Settlement Agreement and/or (iv) other proceeds related to the assets and liabilities received under the Settlement Agreement, then the Company will pay the Advisor a fee in an amount not to exceed 1% of the contract sales price and subject to other conditions set forth in the Advisory Agreement, as determined by the conflicts committee in its sole discretion, which fee will be payable promptly upon such determination by the conflicts committee. As of September 30, 2015 , the Company had sold 161 GKK Properties for an aggregate contract sales price of $214.1 million for which the Company had not paid or accrued a disposition fee. If the conflicts committee determines the Company has recovered its entire investment related to the GKK Mezzanine Loan and the GKK Properties upon the sale of the final GKK Property, the conflicts committee may authorize the Company to pay the Advisor a disposition fee of up to 1% of the aggregate contract sales price of these GKK Properties sold as of September 30, 2015 , which amount would be determined by the conflicts committee in its sole discretion.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company presently operates in three business segments based on its investment types: real estate, real estate-related and commercial properties primarily leased to financial institutions received under the Settlement Agreement, or the GKK Properties. Under the real estate segment, the Company has invested primarily in office and industrial properties located throughout the United States. The real estate segment excludes all real estate properties that were classified as discontinued operations. Under the real estate-related segment, the Company has invested in or originated mortgage loans, mezzanine loans and other real estate-related assets, including real estate securities. The GKK Properties segment consists of primarily office properties, bank branch properties, operations centers and other properties located in 30 states but excludes GKK Properties that were classified as discontinued operations. All revenues earned from the Company’s three reporting segments were from external customers and there were no intersegment sales or transfers. The Company does not allocate corporate-level accounts to its reporting segments. Corporate-level accounts include corporate general and administrative expenses, asset management fees, non-operating interest income and other corporate-level expenses. The accounting policies of the reporting segments are consistent with those described in Note 2, “Summary of Significant Accounting Policies.” The Company evaluates the performance of its segments based upon net operating income from continuing operations (“NOI”), which is a non-GAAP supplemental financial measure. The Company defines NOI for its real estate segment and the GKK Properties segment as operating revenues (rental income, tenant reimbursements and other operating income) less property and related expenses (property operating expenses, real estate taxes, insurance and provision for bad debt) less interest expense. The Company defines NOI for its real estate-related segment as interest income and income from its unconsolidated joint venture investment less loan servicing costs (if applicable) and interest expense (if applicable). NOI excludes certain items that are not considered to be controllable in connection with the management of an asset such as non-property income and expenses, depreciation and amortization, asset management fees and corporate general and administrative expenses. The Company uses NOI to evaluate the operating performance of the Company’s real estate investments, real estate-related investments and the GKK Properties and to make decisions about resource allocations. The Company believes that net income is the GAAP measure that is most directly comparable to NOI; however, NOI should not be considered as an alternative to net income as the primary indicator of operating performance as it excludes the items described above. Additionally, NOI as defined above may not be comparable to other REITs or companies as their definitions of NOI may differ from the Company’s definition. During the year ended December 31, 2014, the Company revised its definition of NOI to exclude asset management fees, which the Company does not consider to be controllable in connection with the management of each property or real estate-related asset and is viewed by the chief operating decision makers as a corporate-level administrative expense. NOI for all prior periods presented has been adjusted to conform to the current period definition. The following tables summarize total revenues, interest expense and NOI for each reportable segment for the three and nine months ended September 30, 2015 and 2014 , and total assets and total liabilities for each reportable segment as of September 30, 2015 and December 31, 2014 (in thousands): For the Three Months Ended September 30, For the Nine Months Ended September 30, 2015 2014 2015 2014 Revenues: Real estate segment (1) $ 16,520 $ 17,343 $ 50,849 $ 54,496 Real estate-related segment 756 728 2,223 2,343 GKK Properties segment (1) 27,568 34,814 86,315 104,514 Total revenues $ 44,844 $ 52,885 $ 139,387 $ 161,353 Interest expense: Real estate segment (1) $ 2,069 $ 2,158 $ 6,314 $ 7,445 Real estate-related segment — — — — GKK Properties segment (1) 4,956 7,836 17,528 29,130 Total interest expense $ 7,025 $ 9,994 $ 23,842 $ 36,575 NOI: Real estate segment (1) $ 7,055 $ 6,975 $ 20,108 $ 22,921 Real estate-related segment 756 727 2,221 2,206 GKK Properties segment (1) 6,905 8,451 17,635 15,883 Total NOI $ 14,716 $ 16,153 $ 39,964 $ 41,010 As of September 30, As of December 31, 2015 2014 Assets: Real estate segment $ 517,183 $ 542,512 Real estate-related segment 27,532 29,096 GKK Properties segment 525,715 575,225 Total segment assets 1,070,430 1,146,833 Real estate held for sale 22,649 182,498 Foreclosed real estate held for sale — 12,045 Corporate-level (2) 95,555 34,791 Total assets $ 1,188,634 $ 1,376,167 Liabilities: Real estate segment $ 244,989 $ 240,965 Real estate-related segment 7 — GKK Properties segment 349,368 414,639 Total segment liabilities 594,364 655,604 Real estate held for sale 18,169 102,152 Corporate-level (3) 1,003 5,638 Total liabilities $ 613,536 $ 763,394 _____________________ (1) Amounts include certain properties in continuing operations that were sold as of September 30, 2015 .

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Lease Obligations Pursuant to the Settlement Agreement, the Company indirectly received leasehold interests in certain commercial properties, pursuant to leases between the owner of the property, as landlord, and the Company, as tenant. The ground leases have expiration dates from 2016 through 2042 and the building leases have expiration dates from 2016 through 2085. These lease obligations generally contain rent increases and renewal options. In certain instances, the rent owed by the Company to the owner of the property under the lease is greater than the revenue received by the Company from the tenants occupying the property. Future minimum lease payments owed by the Company under non-cancelable operating building and ground leases as of September 30, 2015 were as follows (in thousands): October 1, 2015 through December 31, 2015 $ 4,244 2016 16,642 2017 12,644 2018 2,440 2019 1,774 Thereafter 31,471 $ 69,215 If the Company was to dispose of an asset that is subject to a ground lease, the Company may incur additional losses to settle obligations related to the ground lease. Economic Dependency The Company is dependent on the Advisor for certain services that are essential to the Company, including the management of the Company’s real estate and real estate-related investment portfolio; the disposition of real estate and real estate-related investments; and other general and administrative responsibilities. In the event that the Advisor is unable to provide any of these services, the Company will be required to obtain such services from other sources. The Company is also dependent on the Property Manager for the Services under the Amended Services Agreement, including the operations, leasing and eventual dispositions of the GKK Properties. Environmental As an owner of real estate, the Company is subject to various environmental laws of federal, state and local governments. Although there can be no assurance, the Company is not aware of any environmental liability that could have a material adverse effect on its financial condition or results of operations. However, changes in applicable environmental laws and regulations, the uses and conditions of properties in the vicinity of the Company’s properties, the activities of its tenants and other environmental conditions of which the Company is unaware with respect to the properties could result in future environmental liabilities. Under the Settlement Agreement, the Company indirectly took title to or, with respect to a limited number of the GKK Properties, indirectly took a leasehold interest in, the GKK Properties on an “as is” basis. As such, the Company was not able to inspect the GKK Properties or conduct standard due diligence on certain of the GKK Properties before the transfers of the properties. Additionally, the Company did not receive representations, warranties and indemnities relating to the GKK Properties from Gramercy and/or its affiliates. Thus, the value of the GKK Properties may decline if the Company subsequently discovers environmental problems with the GKK Properties. Legal Matters From time to time, the Company is party to legal proceedings that arise in the ordinary course of its business. Management is not aware of any legal proceedings the outcome of which is probable or reasonably possible to have a material adverse effect on the Company’s results of operations or financial condition, which would require accrual or disclosure of the contingency and possible range of loss. Additionally, the Company has not recorded any loss contingencies related to legal proceedings in which the potential loss is deemed to be remote.

The Company expects to pay this distribution on or about December 28, 2015. Disposition of Waltham Main and Partial Defeasance of the BBD2 Loan On October 1, 2015, the Company, through an indirect wholly owned subsidiary, sold an office building containing 303,460 rentable square feet located in Waltham, Massachusetts (“Waltham Main”) to a purchaser unaffiliated with the Company or its advisor for $52.5 million or $51.0 million net of concessions and credits. In connection with the disposition of Waltham Main, the Company, through an indirect wholly owned subsidiary, entered into a partial defeasance with the lender under the BBD2 Loan to defease $40.8 million of the outstanding principal balance, releasing Waltham Main and 21 other properties secured by the BBD2 Loan. BBD2 Loan bears interest rate of 5.96% and matures on September 8, 2019. The defeasance costs and write-offs of unamortized deferred financing costs and an unamortized discount resulted in a loss on extinguishment of debt of approximately $8.0 million . On October 1, 2015, the outstanding principal balance remaining on the BBD2 Loan was $93.4 million . Defeasance of the Sterling Bank Mortgage Loan On October 9, 2015, the Company, through an indirect wholly owned subsidiary, entered into a defeasance with the lender under the Sterling Bank Mortgage Loan to defease the entire outstanding principal balance of $19.6 million , releasing all the properties secured by the Sterling Bank Mortgage Loan. The Sterling Bank Mortgage Loan bore interest at a rate of 5.57% and was due to mature on January 11, 2017. The defeasance costs and write-off of an unamortized discount resulted in a loss on extinguishment of debt of approximately $1.2 million . Renewal of Advisory Agreement On November 8, 2015, the Company renewed the Advisory Agreement with the Advisor. The renewed Advisory Agreement is effective through November 8, 2016; however, either party may terminate the renewed Advisory Agreement without cause or penalty upon providing 60 days’ written notice. The terms of the renewed Advisory Agreement are identical to those of the Advisory Agreement that was previously in effect, including the January 15, 2015 amendment to the previous Advisory Agreement.

SUMMARY OF SIGNIFICANT ACCOUN23

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2015
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements and condensed notes thereto have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the SEC, including the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for audited financial statements. In the opinion of management, the financial statements for the unaudited interim periods presented include all adjustments, which are of a normal and recurring nature, necessary for a fair and consistent presentation of the results for such periods. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 .
Principles of Consolidation	The consolidated financial statements include the accounts of the Company, KBS REIT Holdings, the Operating Partnership and their direct and indirect wholly owned subsidiaries. All significant intercompany balances and transactions are eliminated in consolidation.
Use of Estimates	The preparation of the consolidated financial statements and condensed notes thereto in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates.
Reclassifications	Certain amounts in the Company’s prior period consolidated financial statements have been reclassified to conform to the current period presentation. These reclassifications have not changed the results of operations of prior periods. During the nine months ended September 30, 2015 , the Company sold seven properties (of which five were GKK Properties), two of which were held for sale as of December 31, 2014. As a result, certain assets and liabilities were reclassified to held for sale on the consolidated balance sheets for all periods presented. Operating results of properties that were classified as held for sale in financial statements prior to January 1, 2014 will remain in discontinued operations on the Company’s consolidated statements of operations. Operating results of properties that were disposed of or classified as held for sale in the ordinary course of business subsequent to January 1, 2014 that had not been classified as held for sale in financial statements issued for the reporting periods prior to January 1, 2014 are included in continuing operations on the Company’s consolidated statements of operations.
Per Share Data	Basic net income (loss) per share of common stock is calculated by dividing net income (loss) by the weighted-average number of shares of common stock issued and outstanding during such period. Diluted net income (loss) per share of common stock equals basic net income (loss) per share of common stock as there were no potentially dilutive securities outstanding during the three and nine months ended September 30, 2015 and 2014 , respectively. Distributions declared per share of common stock were $0.025 and $0.075 for the three and nine months ended September 30, 2015 , respectively. On March 6, 2015, the Company’s board of directors declared a distribution in the amount of $0.025 per share of common stock to stockholders of record as of the close of business on March 20, 2015. On May 13, 2015, the Company’s board of directors declared a distribution in the amount of $0.025 per share of common stock to stockholders of record as of the close of business on June 19, 2015. On August 11, 2015, the Company’s board of directors declared a distribution in the amount of $0.025 per share of common stock to stockholders of record as of the close of business on September 18, 2015. Distributions declared per share of common stock were $0.025 and $0.025 for the three and nine months ended September 30, 2014 , respectively. On September 30, 2014, the Company's board of directors declared a distribution in the amount of $0.025 per share of common stock to stockholders of record as of the close of business on September 30, 2014.
Segments	The Company’s segments are based on the Company’s method of internal reporting, which classifies its operations by investment type: (i) real estate, (ii) real estate-related and (iii) commercial properties primarily leased to financial institutions received under the Settlement Agreement, the GKK Properties. For financial data by segment, see Note 12, “Segment Information.”
Recently Issued Accounting Standards Update	In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU No. 2014-09”). ASU No. 2014-09 requires an entity to recognize the revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. ASU No. 2014-09 supersedes the revenue requirements in Revenue Recognition (Topic 605) and most industry-specific guidance throughout the Industry Topics of the Codification. ASU No. 2014-09 does not apply to lease contracts within the scope of Leases (Topic 840). ASU No. 2014-09 was to be effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and is to be applied retrospectively, with early application not permitted. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date (“ASU No. 2015-14”), which defers the effective date of ASU No. 2014-09 by one year. Early adoption is permitted but not before the original effective date. The Company is still evaluating the impact of adopting ASU No. 2014-09 on its financial statements, but does not expect the adoption of ASU No. 2014-09 to have a material impact on its financial statements. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements (Subtopic 205-40) , Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU No. 2014-15”). The amendments in ASU No. 2014-15 require management to evaluate, for each annual and interim reporting period, whether there are conditions or events, considered in the aggregate, that raise substantial doubt about an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued (or are available to be issued when applicable) and, if so, provide related disclosures. ASU No. 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early adoption is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. The Company does not expect the adoption of ASU No. 2014-15 to have a significant impact on its financial statements. In January 2015, the FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20), Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items (“ASU No. 2015-01”). The amendments in ASU No. 2015-01 eliminate from GAAP the concept of extraordinary items. Although the amendments will eliminate the requirements in Subtopic 225-20 for reporting entities to consider whether an underlying event or transaction is extraordinary, the presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. ASU No. 2015-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect the adoption of ASU No. 2015-01 to have a significant impact on its financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30), Simplifying the Presentation of Debt Issuance Costs (“ASU No. 2015-03”). The amendments in ASU No. 2015-03 require debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. ASU No. 2015-03 is limited to the presentation of debt issuance costs and does not affect the recognition and measurement of debt issuance costs. Given the absence of authoritative guidance within ASU No. 2015-03 for debt issuance costs related to line-of-credit arrangements, in August 2015, the FASB issued ASU No. 2015-15, Interest - Imputation of Interest (Subtopic 835-30), Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (“ASU No. 2015-15”), which clarifies ASU No. 2015-03 by stating that the staff of the SEC would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU No. 2015-03 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015 and is to be applied retrospectively. Early adoption is permitted for financial statements that have not been previously issued. The adoption of ASU No. 2015-03 would change the presentation of debt issuance costs as the Company presents debt issuance costs as deferred financing costs, prepaid expenses and other assets on the accompanying consolidated balance sheets. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805), Simplifying the Accounting for Measurement-Period Adjustments (“ASU No. 2015-16”). The amendments in ASU No. 2015-16 require that in a business combination, an acquirer recognizes adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. ASU No. 2015-16 is effective for annual periods beginning after December 15, 2015, and interim periods within those fiscal years and is to be applied prospectively. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect the adoption of ASU No. 2015-16 to have a significant impact on its financial statements.
