SUMMARY OF SIGNIFICANT ACCOUNTI

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 Securities and Exchange Commission (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 six months ended June 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 II, 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 six months ended June 30, 2015 , the Company sold one office property. As a result, certain assets and liabilities were reclassified to held for sale on the consolidated balance sheets for all periods presented. Additionally, as of June 30, 2015 , the Company reclassified two properties that were previously classified as held for sale to held for investment. 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 six months ended June 30, 2015 and 2014 , respectively. Distributions declared per common share were $0.073 and $0.145 for the three and six months ended June 30, 2015 , respectively. Distributions declared per common share assumes each share was issued and outstanding each day that was a record date for distributions during the six months ended June 30, 2015 . These distributions declared consisted of the following: • On January 15, 2015, the Company’s board of directors declared January 2015 and February 2015 distributions in the amounts of $0.02488493 and $0.02247671 , respectively, per share of common stock to stockholders of record as of the close of business on January 29, 2015 and February 26, 2015, respectively. • On March 6, 2015, the Company’s board of directors declared March 2015 and April 2015 distributions in the amounts of $0.02488493 and $0.02408219 , respectively, per share of common stock to stockholders of record as of the close of business on March 20, 2015 and April 20, 2015, respectively. • On May 13, 2015, the Company’s board of directors declared May 2015 and June 2015 distributions in the amounts of $0.02488493 and $0.02408219 , respectively, per share of common stock to stockholders of record as of the close of business on May 20, 2015 and June 19, 2015, respectively. Distributions declared per common share were $0.162 and $0.322 for the three and six months ended June 30, 2014 , respectively. Distributions declared per common share assumes each share was issued and outstanding each day during the three and six months ended June 30, 2014 . For each day that was a record date for distributions during the three and six months ended June 30, 2014 , distributions were calculated at a rate of $0.00178082 per share per day. Each day during the period from January 1, 2014 through June 30, 2014 was a record date for distributions. Segments The Company’s segments are based on the Company’s method of internal reporting, which classifies its operations by investment type: real estate and real estate-related. For financial data by segment, see Note 11, “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 is 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. On July 9, 2015, the FASB voted to defer 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. 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.

Operating Leases The Company’s real estate properties are leased to tenants under operating leases for which the terms and expirations vary. As of June 30, 2015 , the leases had remaining terms, excluding options to extend, of up to 14.3 years with a weighted-average remaining term of 4.3 years. Some of the leases have provisions to extend the term of the leases, options for early termination for all or 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. 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 $2.5 million and $2.5 million as of June 30, 2015 and December 31, 2014 , respectively. During the six months ended June 30, 2015 and 2014 , the Company recognized deferred rent from tenants, net of lease incentive amortization, of $2.6 million and $3.7 million , respectively. As of June 30, 2015 and December 31, 2014 , the cumulative deferred rent balance was $42.4 million and $39.4 million , respectively, and is included in rents and other receivables on the accompanying balance sheets. The cumulative deferred rent balance included $4.1 million and $4.0 million of unamortized lease incentives as of June 30, 2015 and December 31, 2014 , respectively. As of June 30, 2015 , the future minimum rental income from the Company’s properties under non-cancelable operating leases was as follows (in thousands): July 1, 2015 through December 31, 2015 $ 62,393 2016 125,634 2017 117,028 2018 101,102 2019 80,835 Thereafter 369,600 $ 856,592 As of June 30, 2015 , the Company had over 250 tenants over a diverse range of industries and geographic areas. The Company’s highest tenant industry concentrations (greater than 10% of annualized base rent) were as follows: Industry Number of Tenants Annualized Base Rent (1) (in thousands) Percentage of Annualized Base Rent Finance 31 $ 30,170 22.1 % Computer System Design & Programming 10 25,792 18.9 % $ 55,962 41.0 % _____________________ (1) Annualized base rent represents annualized contractual base rental income as of June 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. No other tenant industries accounted for more than 10% of annualized base rent. The Company had not identified any material tenant credit issues as of June 30, 2015 . During the six months ended June 30, 2015 and 2014 , the Company recorded bad debt expense of $0.1 million and $0.4 million , respectively. As of June 30, 2015 , the Company had a bad debt expense reserve of approximately $0.2 million , which represented less than 1% of its annualized base rent. As of June 30, 2015 , the Company had a concentration of credit risk related to the following tenant lease that represented more than 10% of the Company’s annualized base rent: Annualized Base Rent Statistics Tenant Property Tenant Industry Square Feet % of Portfolio (Net Rentable Sq.

(2) Represents the expiration date of the lease as of June 30, 2015 and does not take into account any tenant renewal or termination options. Geographic Concentration Risk As of June 30, 2015 , the Company’s net investments in real estate in California and New Jersey represented 31.5% and 19.1% of the Company’s total assets, respectively. As a result, the geographic concentration of the Company’s portfolio makes it particularly susceptible to adverse economic developments in the California and New Jersey real estate markets. Any adverse economic or real estate developments in these markets, such as business layoffs or downsizing, industry slowdowns, relocations of businesses, changing demographics and other factors, or any decrease in demand for office space resulting from the local business climate, could adversely affect the Company’s operating results and its ability to make distributions to stockholders. Impairment of Real Estate During the six months ended June 30, 2015 , the Company recorded impairment charges of $4.5 million with respect to two real estate properties that were reclassified from held for sale to held for investment. The impairment charge was recorded to adjust the carrying values of the properties for any depreciation and amortization expense that would have been recognized if the properties had always been classified as held for investment, which otherwise would have been recorded through depreciation and amortization expense.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS The Company enters into derivative instruments for risk management purposes to hedge its exposure to cash flow variability caused by changing interest rates. The primary goal of the Company’s risk management practices related to interest rate risk is to prevent changes in interest rates from adversely impacting the Company’s ability to achieve its investment return objectives. The Company does not enter into derivatives for speculative purposes. The Company enters into interest rate swaps as a fixed rate payer to mitigate its exposure to rising interest rates on its variable rate notes payable. The value of interest rate swaps is primarily impacted by interest rates, market expectations about interest rates, and the remaining life of the instrument. In general, increases in interest rates, or anticipated increases in interest rates, will increase the value of the fixed rate payer position and decrease the value of the variable rate payer position. As the remaining life of the interest rate swap decreases, the value of both positions will generally move towards zero. The following table summarizes the notional amount and other information related to the Company’s interest rate swaps as of June 30, 2015 and December 31, 2014 . The notional amount is an indication of the extent of the Company’s involvement in each instrument at that time, but does not represent exposure to credit, interest rate or market risks (dollars in thousands): Derivative Instruments June 30, 2015 December 31, 2014 Reference Rate as of June 30, 2015 Weighted-Average Fix Pay Rate Weighted-Average Remaining Term in Years Number of Instruments Notional Amount Number of Instruments Notional Amount Interest Rate Swaps (1) 9 $519,175 11 $596,575 One-month LIBOR/ 1.27% 0.9 _____________________ (1) During the six months ended June 30, 2015 , the Company terminated one interest rate swap agreement and paid an aggregate breakage fee of $0.2 million . Also, one of the Company’s interest rate swaps expired during the six months ended June 30, 2015 . As of June 30, 2015 and December 31, 2014 , none of the Company’s interest rate swaps were designated as cash flow hedges. The following table sets forth the fair value of the Company’s derivative instruments as well as their classification on the consolidated balance sheets as of June 30, 2015 and December 31, 2014 (dollars in thousands): Derivative Instruments Balance Sheet Location June 30, 2015 December 31, 2014 Number of Instruments Fair Value Number of Instruments Fair Value Interest Rate Swaps Deferred financing costs, prepaid expenses and other assets, at fair value — $ — 2 $ 122 Interest Rate Swaps Other liabilities, at fair value 9 $ (2,678 ) 9 $ (4,749 ) The change in fair value of the effective portion of a derivative instrument that is designated as a cash flow hedge is recorded as other comprehensive income (loss) in the accompanying consolidated statements of comprehensive income (loss) and as other comprehensive income in the accompanying consolidated statements of stockholders’ equity. Amounts in other comprehensive income (loss) will be reclassified into earnings in the periods in which earnings are affected by the hedged cash flow. The change in fair value of the ineffective portion is recognized directly in earnings. With respect to swap agreements that were terminated for which it remains probable that the original hedged forecasted transactions (i.e., LIBOR-based debt service payments) will occur, the loss related to the termination of these swap agreements is included in accumulated other comprehensive income (loss) and is reclassified into earnings over the period of the original forecasted hedged transaction. The change in fair value of a derivative instrument that is not designated as a cash flow hedge is recorded as interest expense in the accompanying consolidated statements of operations.

During 2014, the Company dedesignated all of its interest rate swap instruments due to the anticipated early repayment of debt in connection with asset sales, and therefore, certain hedged forecasted transactions were no longer probable beyond the projected asset sale date.

FAIR VALUE DISCLOSURES

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, 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: The Company’s real estate loans receivable 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. Derivative instruments: The Company’s derivative instruments are presented at fair value on the accompanying consolidated balance sheets. The valuation of these instruments is determined using a proprietary model that utilizes observable inputs. As such, the Company classifies these inputs as Level 2 inputs. The proprietary model uses the contractual terms of the derivatives, including the period to maturity, as well as observable market-based inputs, including interest rate curves and volatility. The fair values of interest rate swaps are estimated using the market standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments, which consider the impact of any credit risks to the contracts, are incorporated in the fair values to account for potential nonperformance risk. Notes payable: The fair value of the Company’s notes payable is 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 liabilities 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 June 30, 2015 and December 31, 2014 , which carrying amounts do not generally approximate the fair values (in thousands): June 30, 2015 December 31, 2014 Face Value Carrying Amount Fair Value Face Value Carrying Amount Fair Value Financial assets: Real estate loans receivable $ 72,595 $ 72,620 $ 73,906 $ 72,908 $ 72,940 $ 73,414 Financial liabilities: Notes payable $ 700,911 $ 700,911 $ 701,759 $ 790,611 $ 790,611 $ 794,439 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. Despite increased capital market and credit market activity, transaction volume for certain financial instruments remains relatively low. This has made the estimation of fair values difficult and, therefore, both the actual results and the Company’s estimate of value at a future date could be materially different. As of June 30, 2015 , the Company measured the following liabilities at fair value (in thousands): Fair Value Measurements Using Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Recurring Basis: Liability derivatives $ 2,678 $ — $ 2,678 $ —

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS The Company has entered into the Advisory Agreement with the Advisor. This agreement entitles the Advisor to specified fees upon the provision of certain services with regard to the management of the Company’s investments, among other services, and the disposition of investments, as well as reimbursement of 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 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 Depository Trust & Clearing Corporation Alternative Investment Product Platform with respect to certain accounts of the Company’s investors serviced through the platform. The Advisor and Dealer Manager also serve as the advisor and dealer manager, respectively, for KBS Real Estate Investment Trust, 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, 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 six months ended June 30, 2015 and 2014 , no other business transactions occurred between the Company and KBS Real Estate Investment Trust, 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. Pursuant to the terms of these agreements, summarized below are the related-party costs incurred by the Company for the three and six months ended June 30, 2015 and 2014 , respectively, and any related amounts payable as of June 30, 2015 and December 31, 2014 (in thousands): Incurred Payable as of Three Months Ended June 30, Six Months Ended June 30, June 30, December 31, 2015 2014 2015 2014 2015 2014 Expensed Asset management fees $ 3,022 $ 5,631 $ 6,108 $ 11,335 $ — $ — Reimbursement of operating expenses (1) 40 37 79 73 43 38 Disposition fees (2) — 2,563 1,239 2,563 — — $ 3,062 $ 8,231 $ 7,426 $ 13,971 $ 43 $ 38 _____________________ (1) 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 $35,000 and $37,000 for the three months ended June 30, 2015 and 2014 , respectively, and $68,000 and $73,000 for the six months ended June 30, 2015 and 2014 , respectively, and were the only type of employee costs reimbursed under the Advisory Agreement for the six months ended June 30, 2015 and 2014 . The Company will not reimburse for employee costs in connection with services for which the Advisor earns acquisition, origination or 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. (2) Disposition fees with respect to real estate sold are included in the gain on sale of real estate, net in the accompanying consolidated statements of operations. Disposition fees with respect to real estate loans receivable sold are included in the gain on payoff or sale of real estate loans receivable in the accompanying consolidated statements of operations.

SEGMENT INFORMATION

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company presently operates in two reportable business segments based on its investment types: real estate and real estate-related. Under the real estate segment, the Company has invested in office, office/flex and industrial properties. Under the real estate-related segment, the Company has invested in or originated mortgage loans and an A-Note. All revenues earned from the Company’s two 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, non-operating interest expense and other corporate-level expenses. The accounting policies of the 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 (“NOI”), which is a non-GAAP supplemental financial measure. The Company defines NOI for its real estate 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 less loan servicing costs and interest expense. 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 and real estate-related investments 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 and NOI for each reportable segment for the three and six months ended June 30, 2015 and 2014 and total assets and total liabilities for each reportable segment as of June 30, 2015 and December 31, 2014 (in thousands): For the Three Months Ended June 30, For the Six Months Ended June 30, 2015 2014 2015 2014 Revenues: Real estate segment (1) $ 39,829 $ 80,641 $ 82,397 $ 165,132 Real estate-related segment 1,374 1,986 2,736 9,950 Total segment revenues 41,203 82,627 85,133 175,082 Corporate-level — 89 — 89 Total revenues $ 41,203 $ 82,716 $ 85,133 $ 175,171 Interest Expense: Real estate segment (1) $ 5,605 $ 14,626 $ 12,452 $ 28,855 Real estate-related segment — 587 — 993 Total interest expense $ 5,605 $ 15,213 $ 12,452 $ 29,848 NOI: Real estate segment (1) $ 20,912 $ 37,216 $ 41,270 $ 77,014 Real estate-related segment 1,370 1,399 2,724 8,906 Total segment NOI 22,282 38,615 43,994 85,920 Corporate-level — 89 — 89 Total NOI $ 22,282 $ 38,704 $ 43,994 $ 86,009 As of June 30, As of December 31, 2015 2014 Assets: Real estate segment $ 1,300,394 $ 1,317,990 Real estate-related segment 73,638 73,457 Total segment assets 1,374,032 1,391,447 Real estate held for sale — 97,971 Corporate-level (2) 180,144 168,098 Total assets $ 1,554,176 $ 1,657,516 Liabilities: Real estate segment $ 737,456 $ 774,173 Real estate-related segment — 2 Total segment liabilities 737,456 774,175 Real estate held for sale — 66,676 Corporate-level (3) 5,064 7,138 Total liabilities $ 742,520 $ 847,989 _____________________ (1) Amounts include properties sold.

SUMMARY OF SIGNIFICANT ACCOUN21

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 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 six months ended June 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 II, 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 six months ended June 30, 2015 , the Company sold one office property. As a result, certain assets and liabilities were reclassified to held for sale on the consolidated balance sheets for all periods presented. Additionally, as of June 30, 2015 , the Company reclassified two properties that were previously classified as held for sale to held for investment.
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 six months ended June 30, 2015 and 2014 , respectively. Distributions declared per common share were $0.073 and $0.145 for the three and six months ended June 30, 2015 , respectively. Distributions declared per common share assumes each share was issued and outstanding each day that was a record date for distributions during the six months ended June 30, 2015 . These distributions declared consisted of the following: • On January 15, 2015, the Company’s board of directors declared January 2015 and February 2015 distributions in the amounts of $0.02488493 and $0.02247671 , respectively, per share of common stock to stockholders of record as of the close of business on January 29, 2015 and February 26, 2015, respectively. • On March 6, 2015, the Company’s board of directors declared March 2015 and April 2015 distributions in the amounts of $0.02488493 and $0.02408219 , respectively, per share of common stock to stockholders of record as of the close of business on March 20, 2015 and April 20, 2015, respectively. • On May 13, 2015, the Company’s board of directors declared May 2015 and June 2015 distributions in the amounts of $0.02488493 and $0.02408219 , respectively, per share of common stock to stockholders of record as of the close of business on May 20, 2015 and June 19, 2015, respectively. Distributions declared per common share were $0.162 and $0.322 for the three and six months ended June 30, 2014 , respectively. Distributions declared per common share assumes each share was issued and outstanding each day during the three and six months ended June 30, 2014 . For each day that was a record date for distributions during the three and six months ended June 30, 2014 , distributions were calculated at a rate of $0.00178082 per share per day. Each day during the period from January 1, 2014 through June 30, 2014 was a record date for distributions.
Segments	The Company’s segments are based on the Company’s method of internal reporting, which classifies its operations by investment type: real estate and real estate-related. For financial data by segment, see Note 11, “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 is 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. On July 9, 2015, the FASB voted to defer 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. 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.
