Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION
	KBS Real Estate Investment Trust II, Inc. (the “Company”) was formed on July 12, 2007 as a Maryland corporation that elected to be taxed as a real estate investment trust (“REIT”) beginning with the taxable year ended December 31, 2008. The Company conducts its business primarily through KBS Limited Partnership II, a Delaware limited partnership formed on August 23, 2007 (the “Operating Partnership”), and its subsidiaries. The Company is the sole general partner of and directly owns a 0.1% partnership interest in the Operating Partnership. The Company’s wholly-owned subsidiary, KBS REIT Holdings II LLC, a Delaware limited liability company formed on August 23, 2007 (“KBS REIT Holdings II”), owns the remaining 99.9% partnership interest in the Operating Partnership and is its sole limited partner.
	The Company owns a diverse portfolio of real estate and real estate-related investments. As of December 31, 2014, the Company owned 13 real estate properties (consisting of 11 office properties, one office/flex property and an office campus consisting of eight office buildings) and two real estate loans receivable. As of December 31, 2014, three office properties were classified as held for sale.
	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 the Company renewed with the Advisor on May 21, 2013 (the “Advisory Agreement”). 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, as amended and restated on April 30, 2010 (the “Dealer Manager Agreement”). The Company ceased offering shares of common stock in its primary offering on December 31, 2010 and terminated its primary offering on March 22, 2011. The Company terminated its dividend reinvestment plan effective May 29, 2014.
	The Company sold 182,681,633 shares of common stock in its primary offering for gross offering proceeds of $1.8 billion. The Company sold 30,903,504 shares of common stock under its dividend reinvestment plan for gross offering proceeds of $298.2 million. Also as of December 31, 2014, the Company had redeemed 23,043,534 shares sold in the Offering for $229.5 million.

SUMMARY_OF_SIGNIFICANT_ACCOUNT

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Principles of Consolidation and Basis of Presentation
	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.
	The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the Securities and Exchange Commission (“SEC”).
	Use of Estimates
	The preparation of the consolidated financial statements and the accompanying 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 year ended December 31, 2014, the Company sold nine office properties, one industrial property, a portfolio of four industrial properties and a leasehold interest in one industrial property and classified three office properties as held for sale.  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 December 31, 2014, the Company reclassified two properties that were previously classified as held for sale to held for investment.
	Revenue Recognition
	Real Estate
	The Company recognizes minimum rent, including rental abatements, lease incentives and contractual fixed increases attributable to operating leases, on a straight-line basis over the term of the related leases when collectibility is reasonably assured and records amounts expected to be received in later years as deferred rent receivable. If the lease provides for tenant improvements, the Company determines whether the tenant improvements, for accounting purposes, are owned by the tenant or the Company. When the Company is the owner of the tenant improvements, the tenant is not considered to have taken physical possession or have control of the physical use of the leased asset until the tenant improvements are substantially completed. When the tenant is the owner of the tenant improvements, any tenant improvement allowance (including amounts that a tenant can take in the form of cash or a credit against its rent) that is funded is treated as a lease incentive and amortized as a reduction of revenue over the lease term. Tenant improvement ownership is determined based on various factors including, but not limited to:
	•	whether the lease stipulates how a tenant improvement allowance may be spent;
	•	whether the amount of a tenant improvement allowance is in excess of market rates;
	•	whether the tenant or landlord retains legal title to the improvements at the end of the lease term;
	•	whether the tenant improvements are unique to the tenant or general-purpose in nature; and
	•	whether the tenant improvements are expected to have any residual value at the end of the lease.
	The Company makes estimates of the collectibility of its tenant receivables related to base rents, including deferred rent receivable, expense reimbursements and other revenue or income. Management specifically analyzes accounts receivable, deferred rent receivable, historical bad debts, customer creditworthiness, current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. In addition, with respect to tenants in bankruptcy, management makes estimates of the expected recovery of pre-petition and post-petition claims in assessing the estimated collectibility of the related receivable. In some cases, the ultimate resolution of these claims can exceed one year. When a tenant is in bankruptcy, the Company will record a bad debt reserve for the tenant’s receivable balance and generally will not recognize subsequent rental revenue until cash is received or until the tenant is no longer in bankruptcy and has the ability to make rental payments.
	Real Estate Loans Receivable
	Interest income on the Company’s real estate loans receivable is recognized on an accrual basis over the life of the investment using the interest method. Direct loan origination fees and origination or acquisition costs, as well as acquisition premiums or discounts, are amortized over the term of the loan as an adjustment to interest income. The Company will place loans on nonaccrual status when any portion of principal or interest is 90 days past due, or earlier when concern exists as to the ultimate collection of principal or interest. When a loan is placed on nonaccrual status, the Company will reverse the accrual for unpaid interest and generally will not recognize subsequent interest income until the cash is received, or the loan returns to accrual status. The Company will resume the accrual of interest if it determines the collection of interest according to the contractual terms of the loan is probable.
	Cash and Cash Equivalents
	The Company recognizes interest income on its cash and cash equivalents as it is earned and classifies such amounts as other interest income.
	Real Estate
	Depreciation and Amortization
	Real estate costs related to the acquisition and improvement of properties are capitalized and amortized over the expected useful life of the asset on a straight-line basis. Repair and maintenance costs are charged to expense as incurred and significant replacements and betterments are capitalized. Repair and maintenance costs include all costs that do not extend the useful life of the real estate asset. The Company considers the period of future benefit of an asset to determine its appropriate useful life. Expenditures for tenant improvements are capitalized and amortized over the shorter of the tenant’s lease term or expected useful life. The Company anticipates the estimated useful lives of its assets by class to be generally as follows:
	Buildings	25-40 years
	Building improvements	10-25 years
	Tenant improvements	Shorter of lease term or expected useful life
	Tenant origination and absorption costs	Remaining term of related leases, including below-market renewal periods
	Real Estate Acquisition Valuation
	The Company records the acquisition of income-producing real estate or real estate that will be used for the production of income as a business combination. All assets acquired and liabilities assumed in a business combination are measured at their acquisition-date fair values. Acquisition costs are expensed as incurred and restructuring costs that do not meet the definition of a liability at the acquisition date are expensed in periods subsequent to the acquisition date.
	The Company assesses the acquisition date fair values of all tangible assets, identifiable intangibles and assumed liabilities using methods similar to those used by independent appraisers, generally utilizing a discounted cash flow analysis that applies appropriate discount and/or capitalization rates and available market information. Estimates of future cash flows are based on a number of factors, including historical operating results, known and anticipated trends, and market and economic conditions. The fair value of tangible assets of an acquired property considers the value of the property as if it were vacant.
	The Company records above-market and below-market in-place lease values for acquired properties based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of above-market in-place leases and for the initial term plus any extended term for any leases with below-market renewal options. The Company amortizes any recorded above-market or below-market lease values as a reduction or increase, respectively, to rental income over the remaining non-cancelable terms of the respective lease, including any below-market renewal periods.
	The Company estimates the value of tenant origination and absorption costs by considering the estimated carrying costs during hypothetical expected lease up periods, considering current market conditions. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods.
	The Company amortizes the value of tenant origination and absorption costs to depreciation and amortization expense over the remaining non-cancelable term of the leases.
	Estimates of the fair values of the tangible assets, identifiable intangibles and assumed liabilities require the Company to make significant assumptions to estimate market lease rates, property-operating expenses, carrying costs during lease-up periods, discount rates, market absorption periods, and the number of years the property will be held for investment. The use of inappropriate assumptions would result in an incorrect valuation of the Company’s acquired tangible assets, identifiable intangibles and assumed liabilities, which would impact the amount of the Company’s net income.
	Impairment of Real Estate and Related Intangible Assets and Liabilities
	The Company continually monitors events and changes in circumstances that could indicate that the carrying amounts of its real estate and related intangible assets and liabilities may not be recoverable or realized. When indicators of potential impairment suggest that the carrying value of real estate and related intangible assets and liabilities may not be recoverable, the Company assesses the recoverability by estimating whether the Company will recover the carrying value of the real estate and related intangible assets and liabilities through its undiscounted future cash flows and its eventual disposition. If, based on this analysis, the Company does not believe that it will be able to recover the carrying value of the real estate and related intangible assets and liabilities, the Company would record an impairment loss to the extent that the carrying value exceeds the estimated fair value of the real estate and related intangible assets and liabilities.
	Real Estate Held for Sale and Discontinued Operations
	The Company generally considers real estate to be “held for sale” when the following criteria are met: (i) management commits to a plan to sell the property, (ii) the property is available for sale immediately, (iii) the property is actively being marketed for sale at a price that is reasonable in relation to its current fair value, (iv) the sale of the property within one year is considered probable and (v) significant changes to the plan to sell are not expected. Real estate that is held for sale and its related assets are classified as “real estate held for sale” and “assets related to real estate held for sale,” respectively, for all periods presented in the accompanying consolidated financial statements. Notes payable and other liabilities related to real estate held for sale are classified as “notes payable related to real estate held for sale” and “liabilities related to real estate held for sale,” respectively, for all periods presented in the accompanying consolidated financial statements. Real estate classified as held for sale is no longer depreciated and is reported at the lower of its carrying value or its estimated fair value less estimated costs to sell. Additionally, with respect to properties that were classified as held for sale in financial statements prior to January 1, 2014, the Company records the operating results as discontinued operations for all periods presented if the operations have been or are expected to be eliminated and the Company will not have any significant continuing involvement in the operations of the property following the sale. Operating results of properties that were disposed of or classified as held for sale in the ordinary course of business during the year ended December 31, 2014 that had not been classified as held for sale in financial statements prior to January 1, 2014 are included in continuing operations on the Company’s consolidated statements of operations.
	Change in a Plan to Sell
	When real estate is initially considered “held for sale” it is measured at the lower of its depreciated book value or estimated fair value less estimated costs to sell. Changes in the market may compel the Company to decide to reclassify a property that was designated as held for sale to held for investment.  A property that is reclassified from held for sale to held for investment is measured and recorded at the lower of (i) its carrying amount before the property was classified as held for sale, adjusted for any depreciation and amortization expense that would have been recognized had the property been continuously classified as held and used, or (ii) its fair value at the date of the subsequent decision not to sell. Any adjustment to the carrying amount of the property as a result of the reclassification is included in income from continuing operations as an impairment charge on real estate held for investment.
	Real Estate Loans Receivable
	The Company’s real estate loans receivable are recorded at amortized cost, net of loan loss reserves (if any), and evaluated for impairment at each balance sheet date. The amortized cost of a real estate loan receivable is the outstanding unpaid principal balance, net of unamortized acquisition premiums or discounts and unamortized costs and fees directly associated with the origination or acquisition of the loan.
	As of December 31, 2014, there was no loan loss reserve and the Company did not record any impairment losses related to the real estate loans receivable during the years ended December 31, 2014, 2013 and 2012. However, in the future, the Company may experience losses from its investments in loans receivable requiring the Company to record loan loss reserves. Realized losses on individual loans could be material and significantly exceed any recorded reserves.
	The reserve for loan losses is a valuation allowance that reflects management’s estimate of loan losses inherent in the loan portfolio as of the balance sheet date. The reserve is adjusted through “Provision for loan losses” on the Company’s consolidated statements of operations and is decreased by charge-offs to specific loans when losses are confirmed. The reserve for loan losses may include a portfolio-based component and an asset-specific component.
	An asset-specific reserve relates to reserves for losses on loans considered impaired. The Company considers a loan to be impaired when, based upon current information and events, it believes that it is probable that the Company will be unable to collect all amounts due under the contractual terms of the loan agreement. The Company also considers a loan to be impaired if it grants the borrower a concession through a modification of the loan terms or if it expects to receive assets (including equity interests in the borrower) with fair values that are less than the carrying value of the loan in satisfaction of the loan. A reserve is established when the present value of payments expected to be received, observable market prices, the estimated fair value of the collateral (for loans that are dependent on the collateral for repayment) or amounts expected to be received in satisfaction of a loan are lower than the carrying value of that loan.
	A portfolio-based reserve covers the pool of loans that do not have asset-specific reserves. A provision for loan losses is recorded when available information as of each balance sheet date indicates that it is probable that the pool of loans will incur a loss and the amount of the loss can be reasonably estimated. Required reserve balances for this pool of loans are derived from estimated probabilities of default and estimated loss severities assuming a default occurs. On a quarterly basis, the Company’s management assigns estimated probabilities of default and loss severities to each loan in the portfolio based on factors such as the debt service coverage of the underlying collateral, the estimated fair value of the collateral, the significance of the borrower’s investment in the collateral, the financial condition of the borrower and/or its sponsors, the likelihood that the borrower and/or its sponsors would allow the loan to default, the Company’s willingness and ability to step in as owner in the event of default, and other pertinent factors.
	Failure to recognize impairments would result in the overstatement of earnings and the carrying value of the Company’s real estate loans held for investment. Actual losses, if any, could differ significantly from estimated amounts.
	Marketable Securities
	The Company classifies its investments in marketable securities as available-for-sale, since the Company may sell them prior to their maturity but does not hold them principally for the purpose of making frequent investments and sales with the objective of generating profits on short-term differences in price. These investments are carried at estimated fair value, with unrealized gains and losses reported in accumulated other comprehensive income (loss). Estimated fair values are generally based on quoted market prices, when available, or on estimates provided by independent pricing sources or dealers who make markets in such securities. In certain circumstances, such as when the market for the securities becomes inactive, the Company may determine it is appropriate to perform an internal valuation of the securities. Upon the sale of a security, the previously recognized unrealized gain (loss) is reversed out of accumulated other comprehensive income (loss) and the actual realized gain (loss) is recognized in earnings.
	On a quarterly basis, the Company evaluates its marketable securities for other-than-temporary impairment. The Company reviews the projected future cash flows from these securities for changes in assumptions due to prepayments, credit loss experience and other factors. If, based on the Company’s quarterly estimate of cash flows, there has been an adverse change in the estimated cash flows from the cash flows previously estimated, the present value of the revised cash flows is less than the present value previously estimated, and the fair value of the securities is less than their amortized cost basis, an other-than-temporary impairment is deemed to have occurred.
	The Company recognizes interest income on marketable securities that are beneficial interests in securitized financial assets and are rated “AA” and above on an accrual basis according to the contractual terms of the securities. Discounts or premiums are amortized to interest income over the life of the investment using the interest method.
	The Company recognizes interest income on marketable securities that are beneficial interests in securitized financial assets that are rated below “AA” using the effective yield method, which requires the Company to periodically project estimated cash flows related to these securities and recognize interest income at an interest rate equivalent to the estimated yield on the security, as calculated using the security’s estimated cash flows and amortized cost basis, or reference amount. Changes in the estimated cash flows are recognized through an adjustment to the yield on the security on a prospective basis. Projecting cash flows for these types of securities requires significant judgment, which may have a significant impact on the timing of revenue recognized on these investments.
	The Company is required to distinguish between other-than-temporary impairments related to credit and other-than-temporary impairments related to other factors (e.g., market fluctuations) on its debt securities that it does not intend to sell and where it is not likely that the Company will be required to sell the security prior to the anticipated recovery of its amortized cost basis. The Company calculates the credit component of the other-than-temporary impairment as the difference between the amortized cost basis of the security and the present value of its estimated cash flows discounted at the yield used to recognize interest income. The credit component will be charged to earnings and the component related to other factors is recorded to other comprehensive income (loss).
	Cash and Cash Equivalents
	The Company considers all short-term (with an original maturity of three months or less), highly-liquid investments utilized as part of the Company’s cash-management activities to be cash equivalents. Cash equivalents may include cash and short-term investments. Short-term investments are stated at cost, which approximates fair value.
	The Company’s cash and cash equivalents balance exceeds federally insurable limits as of December 31, 2014. The Company monitors the cash balances in its operating accounts and adjusts the cash balances as appropriate; however, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. To date, the Company has experienced no loss or lack of access to cash in its operating accounts.
	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 on its variable rate notes payable. The Company records these derivative instruments at fair value on the accompanying consolidated balance sheets. Derivative instruments designated and qualifying as a hedge of the exposure to variability in expected future cash flows or other types of forecasted transactions are considered cash flow hedges. 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 consolidated statements of equity. The changes in fair value for derivative instruments that are not designated as a hedge or that do not meet the hedge accounting criteria are recorded as gain or loss on derivative instruments in the accompanying consolidated statements of operations.
	The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objectives and strategy for undertaking various hedge transactions. This process includes designating all derivative instruments that are part of a hedging relationship to specific forecasted transactions or recognized obligations on the consolidated balance sheets. The Company also assesses and documents, both at the hedging instrument’s inception and on a quarterly basis thereafter, whether the derivative instruments that are used in hedging transactions are highly effective in offsetting changes in cash flows associated with the respective hedged items. When the Company determines that a derivative instrument ceases to be highly effective as a hedge, or that it is probable the underlying forecasted transaction will not occur, the Company discontinues hedge accounting prospectively and reclassifies amounts recorded in accumulated other comprehensive income (loss) to earnings.
	The termination of a cash flow hedge prior to the maturity date may result in a net derivative instrument gain or loss that continues to be reported in accumulated other comprehensive income (loss) and is reclassified into earnings over the period of the original forecasted hedged transaction (i.e., LIBOR based debt service payments) unless it is probable that the original forecasted hedged transaction will not occur by the end of the originally specified time period (as documented at the inception of the hedging relationship) or within an additional two-month period of time thereafter. If it is probable that the hedged forecasted transaction will not occur either by the end of the originally specified time period or within the additional two-month period of time, that derivative instrument gain or loss reported in accumulated other comprehensive income (loss) shall be reclassified into earnings immediately.
	Deferred Financing Costs
	Deferred financing costs represent commitment fees, loan fees, legal fees and other third-party costs associated with obtaining financing. These costs are amortized over the terms of the respective financing agreements using the interest method. Unamortized deferred financing costs are generally expensed when the associated debt is refinanced or repaid before maturity unless specific rules are met that would allow for the carryover of such costs to the refinanced debt. Costs incurred in seeking financing transactions that do not close are expensed in the period in which it is determined that the financing will not close.
	Fair Value Measurements
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.
When available, the Company utilizes quoted market prices from independent third-party sources to determine fair value and classifies such items in Level 1 or Level 2. In instances where the market for a financial instrument is not active, regardless of the availability of a nonbinding quoted market price, observable inputs might not be relevant and could require the Company to make a significant adjustment to derive a fair value measurement. Additionally, in an inactive market, a market price quoted from an independent third party may rely more on models with inputs based on information available only to that independent third party. When the Company determines the market for a financial instrument owned by the Company to be illiquid or when market transactions for similar instruments do not appear orderly, the Company uses several valuation sources (including internal valuations, discounted cash flow analysis and quoted market prices) and establishes a fair value by assigning weights to the various valuation sources. 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 or 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.
Changes in assumptions or estimation methodologies can have a material effect on these estimated fair values. In this regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in an immediate settlement of the instrument.
The Company considers the following factors to be indicators of an inactive market: (i) there are few recent transactions, (ii) price quotations are not based on current information, (iii) price quotations vary substantially either over time or among market makers (for example, some brokered markets), (iv) indexes that previously were highly correlated with the fair values of the asset or liability are demonstrably uncorrelated with recent indications of fair value for that asset or liability, (v) there is a significant increase in implied liquidity risk premiums, yields, or performance indicators (such as delinquency rates or loss severities) for observed transactions or quoted prices when compared with the Company’s estimate of expected cash flows, considering all available market data about credit and other nonperformance risk for the asset or liability, (vi) there is a wide bid-ask spread or significant increase in the bid-ask spread, (vii) there is a significant decline or absence of a market for new issuances (that is, a primary market) for the asset or liability or similar assets or liabilities, and (viii) little information is released publicly (for example, a principal-to-principal market).
The Company considers the following factors to be indicators of non-orderly transactions: (i) there was not adequate exposure to the market for a period before the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities under current market conditions, (ii) there was a usual and customary marketing period, but the seller marketed the asset or liability to a single market participant, (iii) the seller is in or near bankruptcy or receivership (that is, distressed), or the seller was required to sell to meet regulatory or legal requirements (that is, forced), and (iv) the transaction price is an outlier when compared with other recent transactions for the same or similar assets or liabilities.
Dividend Reinvestment Plan
The Company had a dividend reinvestment plan (the “DRP”) through which its stockholders were able to have their dividends and other distributions reinvested in additional shares of the Company’s common stock. In accordance with the DRP, at such time as the Company announced an updated estimated value per share, participants in the DRP were able to acquire shares of common stock under the plan at a price equal to 95% of the updated estimated value per share of the Company’s common stock. On December 18, 2013, the Company’s board of directors approved an estimated value per share of the Company’s common stock of $10.29 (unaudited) based on the estimated value of the Company’s assets less the estimated value of the Company’s liabilities, divided by the number of shares outstanding, as of September 30, 2013, with the exception of the Company’s real estate properties, which were appraised as of November 30, 2013. Commencing with the January 2, 2014 purchase date, the purchase price per share under the DRP was $9.78. On May 15, 2014, the Company’s board of directors approved the termination of the DRP, which termination was effective May 29, 2014.
Redeemable Common Stock
The Company has a share redemption program that may enable stockholders to sell their shares to the Company in limited circumstances. On May 15, 2014, the Company’s board of directors approved the amendment and restatement of the Company’s share redemption program (the “Amended Share Redemption Program”). The Amended Share Redemption Program provides only for redemptions sought upon a stockholder’s death, “qualifying disability” or “determination of incompetence” (each as defined in the Amended Share Redemption Program, and together with redemptions sought in connection with a stockholders’ death, “special redemptions”) and is limited as further described below.
From November 16, 2013 until the effectiveness of the Amended Share Redemption Program on June 18, 2014, the terms of the Company’s share redemption program were as follows:
Pursuant to the share redemption program, there were several limitations on the Company’s ability to redeem shares under the program:
•	Unless the shares were being redeemed in connection with a special redemption, the Company could not redeem shares unless the stockholder has held the shares for one year.
•	During any calendar year, the Company could redeem only the number of shares that the Company could purchase with the amount of net proceeds from the sale of shares under the Company’s dividend reinvestment plan during the prior calendar year, provided that the Company could not redeem more than $3.0 million of shares in the aggregate each month, excluding shares redeemed in connection with special redemptions; provided, however, the Company could increase the funding available for the redemption of shares pursuant to the Company’s share redemption program upon ten business days’ notice to its stockholders. The Company could provide notice by including such information (a) in a Current Report on Form 8-K or in the Company’s annual or quarterly reports, all publicly filed with the Securities and Exchange Commission or (b) in a separate mailing to the Company’s stockholders.
•	During any calendar year, the Company could redeem no more than 5% of the weighted-average number of shares outstanding during the prior calendar year.
•	The Company had no obligation to redeem shares if the redemption would violate the restrictions on distributions under Maryland General Corporation Law, as amended from time to time, which prohibits distributions that would cause a corporation to fail to meet statutory tests of solvency.
In connection with the amendments to the share redemption program that became effective on November 16, 2013, the Company’s board of directors approved additional funding for the redemption of shares pursuant to the share redemption program as follows: once the Company had redeemed $3.0 million of shares in the aggregate in any month (excluding special redemptions), then an additional $20.0 million of funds in the aggregate was available for the redemption of shares on redemption dates commencing with the November 29, 2013 redemption date (excluding special redemptions) until such $20.0 million of funds was exhausted; provided that, in no event could the Company redeem, during any calendar year, more shares than the number of shares that the Company could purchase with the amount of net proceeds from the sale of shares under the Company’s dividend reinvestment plan during the prior calendar year. The other limitations of the Company’s share redemption program remained in full force and effect. As of March 31, 2014, the Company had exhausted all $20.0 million of these funds.
On March 7, 2014, the Company’s board of directors approved additional funding for the redemption of shares pursuant to the share redemption program. Once the Company had redeemed $3.0 million of shares in the aggregate in any month (excluding shares redeemed in connection with special redemptions), then an additional $30.0 million of funds in the aggregate was available for the redemption of shares on redemption dates commencing with the March 31, 2014 redemption date (excluding special redemptions) until such $30.0 million of funds was exhausted; provided that, in no event could the Company redeem, during any calendar year, more shares than the number of shares that the Company could purchase with the amount of net proceeds from the sale of shares under its dividend reinvestment plan during the prior calendar year. The other limitations of the Company’s share redemption program remained in full force and effect.
Pursuant to the share redemption program, redemptions made in connection with special redemptions were made at a price per share equal to the most recent estimated value per share of the Company’s common stock as of the applicable redemption date. The prices at which the Company redeemed all other shares eligible for redemption is as follows:
•	For those shares held by the redeeming stockholder for at least one year, 92.5% of the Company’s most recent estimated value per share as of the applicable redemption date;
•	For those shares held by the redeeming stockholder for at least two years, 95.0% of the Company’s most recent estimated value per share as of the applicable redemption date;
•	For those shares held by the redeeming stockholder for at least three years, 97.5% of the Company’s most recent estimated value per share as of the applicable redemption date; and
•	For those shares held by the redeeming stockholder for at least four years, 100% of the Company’s most recent estimated value per share as of the applicable redemption date.
Upon effectiveness of the Amended Share Redemption Program on June 18, 2014, the terms of the share redemption program were as follows:
The Company’s board of directors amended and restated the Company’s share redemption program to provide only for redemptions sought in connection with a special redemption. During each calendar year, such special redemptions are limited to an annual dollar amount determined by the board of directors, which may be reviewed during the year and increased or decreased upon ten business days’ notice to the Company’s stockholders. The Company may provide notice by including such information (a) in a Current Report on Form 8-K or in the Company’s annual or quarterly reports, all publicly filed with the Securities and Exchange Commission or (b) in a separate mailing to the stockholders.
Such redemptions are also subject to other limitations described in the Company’s Amended Share Redemption Program, including:
•	During any calendar year, the Company may redeem no more than 5% of the weighted-average number of shares outstanding during the prior calendar year.
•	The Company has no obligation to redeem shares if the redemption would violate the restrictions on distributions under Maryland General Corporation Law, as amended from time to time, which prohibits distributions that would cause a corporation to fail to meet statutory tests of solvency.
Commencing with the June 2014 redemption date, the dollar amount limitation for special redemptions for the remainder of calendar year 2014 was $10.0 million in the aggregate, as may be reviewed and adjusted from time to time by the Company’s board of directors. Based on historical redemption data, the Company’s board of directors believed that the $10.0 million redemption limitation for the remainder of calendar year 2014 would be sufficient for these special redemptions. On December 2, 2014, the Company’s board of directors approved the dollar amount limitation for special redemptions for calendar year 2015 of $10.0 million in the aggregate, as may be reviewed and adjusted from time to time by the Company’s board of directors. Based on historical redemption data, the Company’s board of directors believes that the $10.0 million redemption limitation for calendar year 2015 will be sufficient for these special redemptions.
There were no other changes to the terms of special redemptions, and special redemptions will continue to be made at a price per share equal to the most recent estimated value per share of the Company’s common stock as of the applicable redemption date. The Company currently does not expect to make ordinary redemptions in the future.
On December 18, 2013, the Company’s board of directors approved an estimated value per share of the Company’s common stock of $10.29 (unaudited) based on the estimated value of the Company’s assets less the estimated value of the Company’s liabilities, divided by the number of shares outstanding, as of September 30, 2013, with the exception of the Company’s real estate properties, which were appraised as of November 30, 2013. This estimated value per share was used to calculate the redemption price commencing with the December 2013 redemption date, which was December 31, 2013.
On September 22, 2014, the Company’s board of directors approved an estimated value per share of the Company’s common stock of $6.05 (unaudited) based on the estimated value of Company’s assets less the estimated value of the Company’s liabilities, divided by the number of shares outstanding, all as of June 30, 2014, adjusted for the impact of the $4.50 special distribution declared subsequent to June 30, 2014 and paid on September 23, 2014. The change in the redemption price was effective for the September 2014 redemption date, which was September 30, 2014.
On December 4, 2014, the Company’s board of directors approved an estimated value per share of the Company’s common stock of $5.86 (unaudited) based on the estimated value of the Company’s assets less the estimated value of the Company’s liabilities, divided by the number of shares outstanding, all as of September 30, 2014. The change in the redemption price was effective for the December 2014 redemption date, which was December 31, 2014, and is effective until the estimated value per share is updated.
The estimated value per share was based upon the recommendation and valuation prepared by the Advisor. As with any valuation methodology, the methodologies used are based upon a number of estimates and assumptions that may not be accurate or complete. Different parties with different assumptions and estimates could derive a different estimated value per share, and these differences could be significant. The estimated value per share is not audited and does not represent the fair value of the Company’s assets and liabilities according to GAAP, nor does it represent a liquidation value of the Company’s assets and liabilities or the amount the Company’s shares of common stock would trade at on a national securities exchange. The estimated value per share does not reflect a discount for the fact that the Company is externally managed, nor does it reflect a real estate portfolio premium/discount versus the sum of the individual property values. The estimated value per share also does not take into account estimated disposition costs and fees for real estate properties that are not under contract to sell, debt prepayment penalties or swap breakage fees that could apply upon the prepayment of certain of the Company’s debt obligations or termination of swap related agreements or the impact of restrictions on the assumption of debt.
The value of the Company’s shares will fluctuate over time in response to developments related to individual assets in the portfolio and the management of those assets and in response to the real estate and finance markets. The Company currently expects to utilize the Advisor and/or an independent valuation firm to update the estimated value per share in December of each year, or more frequently, in accordance with recommended Practice Guideline 2013-01, Valuations of Publicly Registered Non-Listed REITs, issued by the Investment Program Association (“IPA”) in April 2013.
The Company’s board of directors may amend, suspend or terminate the share redemption program with 30 days’ notice to its stockholders, provided that the Company may increase or decrease the funding available for the redemption of shares under the program upon ten business days’ notice to stockholders. The Company may provide this notice by including such information in a Current Report on Form 8-K or in the Company’s annual or quarterly reports, all publicly filed with the SEC, or by a separate mailing to its stockholders.
The Company records amounts that are redeemable under the share redemption program as redeemable common stock in the accompanying consolidated balance sheets because the shares are mandatorily redeemable at the option of the holder and therefore their redemption is outside the control of the Company. Pursuant to the share redemption program, beginning in 2014, the maximum amount redeemable under the Company’s share redemption program is limited to an annual dollar amount determined by Company’s board of directors, as described above. However, because the amounts that can be redeemed in future periods are determinable and only contingent on an event that is likely to occur (e.g., the passage of time), the Company presents the amounts available for future redemptions in future periods as redeemable common stock in the accompanying consolidated balance sheets.
The Company classifies financial instruments that represent a mandatory obligation of the Company to redeem shares as liabilities. The Company’s redeemable common shares are contingently redeemable at the option of the holder. When the Company determines it has a mandatory obligation to redeem shares under the share redemption program, it will reclassify such obligations from temporary equity to a liability based upon their respective settlement values.
The Company limits the dollar value of shares that may be redeemed under the share redemption program as described above. For the year ended December 31, 2014, the Company redeemed 4,457,374 shares sold in the Offering for $44.7 million, which represented all redemption requests received in good order and eligible for redemption through the December 2014 redemption date.
Related Party Transactions
The Company has entered into the Advisory Agreement with the Advisor and the Dealer Manager Agreement with the Dealer Manager. These agreements entitled the Advisor and/or the Dealer Manager to specified fees upon the provision of certain services with regard to the Offering and entitle the Advisor to specified fees upon the provision of certain services with regard to the investment of funds in real estate and real estate-related investments, the management of those 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 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 (“AIP 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. and KBS Strategic Opportunity REIT II, Inc. and anticipate that they will serve as the Advisor and Dealer Manager, respectively, for KBS Growth & Income REIT, Inc.
The Company records all related party fees as incurred, subject to any limitations described in the Advisory Agreement.
Acquisition and Origination Fees
The Company paid the Advisor an acquisition fee equal to 0.75% of the cost of investments acquired, including acquisition expenses and any debt attributable to such investments. With respect to investments in and originations of loans, the Company paid an origination fee equal to 1% of the amount funded by the Company to acquire or originate mortgage, mezzanine, bridge or other loans, including any expenses related to such investments and any debt the Company used to fund the acquisition or origination of these loans. The Company did not pay an acquisition fee with respect to investments in loans.
Asset Management Fee
With respect to investments in real estate, the Company pays the Advisor a monthly asset management fee equal to one-twelfth of 0.75% of the amount paid or allocated to acquire the investment, plus the cost of any subsequent development, construction or improvements to the property. This amount includes any portion of the investment that was debt financed and is inclusive of acquisition fees and expenses related thereto. In the case of investments made through joint ventures, the asset management fee will be determined based on the Company’s proportionate share of the underlying investment.
With respect to investments in loans and any investments other than real estate, the Company pays the Advisor a monthly fee calculated, each month, as one-twelfth of 0.75% of the lesser of (i) the amount paid or allocated to acquire or fund the loan or other investment (which amount includes any portion of the investment that was debt financed and is inclusive of acquisition or origination fees and expenses related thereto) and (ii) the outstanding principal amount of such loan or other investment, plus the acquisition or origination fees and expenses related to the acquisition or funding of such investment, as of the time of calculation.
With respect to an investment that has suffered an impairment in value, reduction in cash flow or other negative circumstances, such investment may either be excluded from the calculation of the asset management fee described above or included in such calculation at a reduced value that is recommended by the Advisor and the Company’s management and then approved by a majority of the Company’s independent directors, and this change in the fee will be applicable to an investment upon the earlier to occur of the date on which (i) such investment is sold, (ii) such investment is surrendered to a person other than the Company, its direct or indirect wholly owned subsidiary or a joint venture or partnership in which the Company has an interest, (iii) the Advisor determines that it will no longer pursue collection or other remedies related to such investment, or (iv) the Advisor recommends a revised fee arrangement with respect to such investment. As of December 31, 2014, the Company has not determined to calculate the asset management fee at an adjusted value for any investments or to exclude any investments from the calculation of the asset management fee.
Disposition Fee
For substantial assistance in connection with the sale of properties or other investments, the Company pays the Advisor or its affiliates 1.0% of the contract sales price of each property or other investment sold; provided, however, in no event may the disposition fees paid to Advisor, its affiliates and unaffiliated third parties exceed 6.0% of the contract sales price.
Income Taxes
The Company has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended. To qualify as a REIT, the Company must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of the Company’s annual REIT taxable income to stockholders (which is computed without regard to the dividends-paid deduction or net capital gain and which does not necessarily equal net income as calculated in accordance with GAAP). As a REIT, the Company generally will not be subject to federal income tax on income that it distributes as dividends to its stockholders. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income tax on its taxable income at regular corporate income tax rates and generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four taxable years following the year during which qualification is lost, unless the Internal Revenue Service grants the Company relief under certain statutory provisions. Such an event could materially and adversely affect the Company’s net income and net cash available for distribution to stockholders. However, the Company believes that it is organized and operates in such a manner as to qualify for treatment as a REIT.
The Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. Neither the Company nor its subsidiaries have been assessed interest or penalties by any major tax jurisdictions. The Company’s evaluations were performed for the tax years ended December 31, 2014, 2013 and 2012. As of December 31, 2014, returns for the calendar years 2010 through 2013 remain subject to examination by major tax jurisdictions.
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 years ended December 31, 2014, 2013 and 2012, respectively.
Distributions declared per common share were $5.066 in the aggregate for the year ended December 31, 2014.

These distributions declared consisted of the following:
•	The Company’s board of directors declared distributions per common share based on daily record dates for each day during the period from January 1, 2014 through August 31, 2014.

•	On August 29, 2014, the Company’s board of directors declared September 2014 and October 2014 distributions in the amounts of $0.03277397 and $0.03386644 per share of common stock, respectively, to stockholders of record as of the close of business on September 26, 2014 and October 29, 2014, respectively.
•	On November 10, 2014, the Company’s board of directors declared a November 2014 distribution in the amount of $0.03277397 per share of common stock to stockholders of record as of the close of business on November 26, 2014.

Distributions declared per common share were $0.704 and $0.650 for the years ended December 31, 2013 and 2012, respectively. Distributions declared per common share assumes each share was issued and outstanding each day during the years ended December 31, 2013 and 2012.

Recently Issued Accounting Standards Update
In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360):  Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU No. 2014-08”).  ASU No. 2014-08 limits discontinued operations reporting to disposals of components of an entity that represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when any of the following occurs: a) the component of an entity or group of components of an entity meets the criteria to be classified as held for sale; b) the component of an entity or group of components of an entity is disposed of by sale; or c) the component of an entity or group of components of an entity is disposed of other than by sale.  ASU No. 2014-08 also requires additional disclosures about discontinued operations.  ASU No. 2014-08 is effective for reporting periods beginning after December 15, 2014.  Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company early adopted ASU No. 2014-08 for the reporting period beginning January 1, 2014.  As a result of the adoption of ASU No. 2014-08, results of operations for properties that are classified as held for sale in the ordinary course of business on or subsequent to January 1, 2014 would generally be included in continuing operations on the Company’s consolidated statements of operations, to the extent such disposals did not meet the criteria for classification as a discontinued operation described above. Additionally, any gain or loss on sale of real estate that does not meet the criteria for classification as a discontinued operation would be included in income from continuing operations on the consolidated statements of operations.
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.  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 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 2015-01 to have a significant impact on its financial statements.

	As of December 31, 2014, the following property represented more than 10% of the Company’s total assets:

	(1) Annualized base rent represents annualized contractual base rental income as of December 31, 2014, 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.
	Operating Leases
	The Company’s real estate properties are leased to tenants under operating leases for which the terms and expirations vary. As of December 31, 2014, the leases had remaining terms, excluding options to extend, of up to 14.8 years with a weighted-average remaining term of 4.4 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 $4.6 million as of December 31, 2014 and 2013, respectively.
	During the years ended December 31, 2014, 2013 and 2012, the Company recognized deferred rent from tenants, net of lease incentive amortization, of $5.8 million, $12.8 million and $15.9 million, respectively. As of December 31, 2014 and 2013, the cumulative deferred rent balance was $25.8 million and $21.7 million, respectively, and is included in rents and other receivables on the accompanying balance sheets. The cumulative deferred rent balance included $2.9 million and $2.4 million of unamortized lease incentives as of December 31, 2014 and 2013, respectively.
	As of December 31, 2014, the future minimum rental income from the Company’s properties under non-cancelable operating leases was as follows (in thousands):
	2015	$	95,633
	2016	90,044
	2017	84,293
	2018	67,743
	2019	47,909
	Thereafter	262,260
		$	647,882
	As of December 31, 2014, the Company had over 100 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				Percentage of Annualized Base Rent
				Base Rent (1)
				(in thousands)
	Computer System Design & Programming		10	$	25,787			25.3	%

	(1) Annualized base rent represents annualized contractual base rental income as of December 31, 2014, 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 December 31, 2014. During the years ended December 31, 2014 and 2013, the Company recorded bad debt expense of $0.3 million and $0.6 million, respectively. During the year ended December 31, 2012, the Company reduced its bad debt expense reserve and recorded a net recovery of bad debt related to its tenant receivables of $30,000. As of December 31, 2014, the Company had a bad debt expense reserve of approximately $0.4 million, which represents less than 1% of its annualized base rent.
	As of December 31, 2014, the Company had a concentration of credit risk related to the following tenant leases that represented more than 10% of the Company’s annualized base rent:

	(1) Annualized base rent represents annualized contractual base rental income as of December 31, 2014, 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.
	(2) Represents the expiration date of the lease as of December 31, 2014 and does not take into account any tenant renewal or termination options.
	Geographic Concentration Risk
	As of December 31, 2014, the Company’s net investments in real estate in California and New Jersey represented 18.8% and 18.1% 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 year ended December 31, 2014, the Company recorded impairment charges of $15.6 million, including $10.6 million of impairments with respect to a real estate property held for investment and $3.9 million of impairments with respect to two real estate properties that were reclassified from held for sale to held for investment. The Company recognized an impairment charge during the year ended December 31, 2014 to reduce the carrying value of the Company’s investment in the 300-600 Campus Drive Buildings to its estimated fair value.  The impairment was caused by the Company revising its cash flow projections and the estimated hold period of the investment due to longer than estimated lease-up periods and lower projected rental rates. The impairment charge with respect to two real estate properties that were reclassified from held for sale to held for investment 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 and rental income (related to the amortization of above-market lease assets and below-market lease liabilities). See Note 7, “Real Estate Held for Sale,” for information regarding impairments of assets related to real estate held for sale.

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 December 31, 2014 and 2013. The notional value 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):

	(1) During the year ended December 31, 2014, the Company terminated two interest rate swap agreements and paid an aggregate breakage fee of $0.2 million. In addition, the Company dedesignated 11 interest rate swap instruments due to the anticipated early repayment of debt in connection with asset sales. The Company dedesignated these hedged instruments due to certain hedged forecasted transactions no longer being probable beyond the projected asset sale date. As of 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 December 31, 2014 and 2013 (dollars in thousands):

	Interest Rate Swaps	Other liabilities, at fair value		9	$	(4,749	)	14		$	(10,260	)
	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.

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 December 31, 2014 and 2013, which carrying amounts do not approximate the fair values (in thousands):
			December 31, 2014								December 31, 2013
			Face Value			Carrying Amount		Fair Value			Face Value		Carrying Amount		Fair Value
	Financial assets:
	Real estate loans receivable		$	72,908		$	72,940	$	73,414		$	184,900	$	184,828	$	190,485

	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.
	During the year ended December 31, 2014, the Company measured the following assets and liabilities at fair value (in thousands):
						Fair Value Measurements Using

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 years ended December 31, 2014, 2013 and 2012 and total assets and total liabilities for each reportable segment as of December 31, 2014 and 2013 (in thousands):

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	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.
	The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) as contained within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and the rules and regulations of the Securities and Exchange Commission (“SEC”).
Use of Estimates	The preparation of the consolidated financial statements and the accompanying 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 year ended December 31, 2014, the Company sold nine office properties, one industrial property, a portfolio of four industrial properties and a leasehold interest in one industrial property and classified three office properties as held for sale.  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 December 31, 2014, the Company reclassified two properties that were previously classified as held for sale to held for investment
Revenue Recognition, Real Estate	The Company recognizes minimum rent, including rental abatements, lease incentives and contractual fixed increases attributable to operating leases, on a straight-line basis over the term of the related leases when collectibility is reasonably assured and records amounts expected to be received in later years as deferred rent receivable. If the lease provides for tenant improvements, the Company determines whether the tenant improvements, for accounting purposes, are owned by the tenant or the Company. When the Company is the owner of the tenant improvements, the tenant is not considered to have taken physical possession or have control of the physical use of the leased asset until the tenant improvements are substantially completed. When the tenant is the owner of the tenant improvements, any tenant improvement allowance (including amounts that a tenant can take in the form of cash or a credit against its rent) that is funded is treated as a lease incentive and amortized as a reduction of revenue over the lease term. Tenant improvement ownership is determined based on various factors including, but not limited to:
	•	whether the lease stipulates how a tenant improvement allowance may be spent;
	•	whether the amount of a tenant improvement allowance is in excess of market rates;
	•	whether the tenant or landlord retains legal title to the improvements at the end of the lease term;
	•	whether the tenant improvements are unique to the tenant or general-purpose in nature; and
	•	whether the tenant improvements are expected to have any residual value at the end of the lease.
	The Company makes estimates of the collectibility of its tenant receivables related to base rents, including deferred rent receivable, expense reimbursements and other revenue or income. Management specifically analyzes accounts receivable, deferred rent receivable, historical bad debts, customer creditworthiness, current economic trends and changes in customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. In addition, with respect to tenants in bankruptcy, management makes estimates of the expected recovery of pre-petition and post-petition claims in assessing the estimated collectibility of the related receivable. In some cases, the ultimate resolution of these claims can exceed one year. When a tenant is in bankruptcy, the Company will record a bad debt reserve for the tenant’s receivable balance and generally will not recognize subsequent rental revenue until cash is received or until the tenant is no longer in bankruptcy and has the ability to make rental payments.
Revenue Recognition, Real Estate Loans Receivable	Interest income on the Company’s real estate loans receivable is recognized on an accrual basis over the life of the investment using the interest method. Direct loan origination fees and origination or acquisition costs, as well as acquisition premiums or discounts, are amortized over the term of the loan as an adjustment to interest income. The Company will place loans on nonaccrual status when any portion of principal or interest is 90 days past due, or earlier when concern exists as to the ultimate collection of principal or interest. When a loan is placed on nonaccrual status, the Company will reverse the accrual for unpaid interest and generally will not recognize subsequent interest income until the cash is received, or the loan returns to accrual status. The Company will resume the accrual of interest if it determines the collection of interest according to the contractual terms of the loan is probable.
Revenue Recognition, Cash and Cash Equivalents	The Company recognizes interest income on its cash and cash equivalents as it is earned and classifies such amounts as other interest income.
Real Estate, Depreciation and Amortization	Real estate costs related to the acquisition and improvement of properties are capitalized and amortized over the expected useful life of the asset on a straight-line basis. Repair and maintenance costs are charged to expense as incurred and significant replacements and betterments are capitalized. Repair and maintenance costs include all costs that do not extend the useful life of the real estate asset. The Company considers the period of future benefit of an asset to determine its appropriate useful life. Expenditures for tenant improvements are capitalized and amortized over the shorter of the tenant’s lease term or expected useful life. The Company anticipates the estimated useful lives of its assets by class to be generally as follows:
	Buildings	25-40 years
	Building improvements	10-25 years
	Tenant improvements	Shorter of lease term or expected useful life
	Tenant origination and absorption costs	Remaining term of related leases, including below-market renewal periods
Real Estate, Acquisition Valuation	The Company records the acquisition of income-producing real estate or real estate that will be used for the production of income as a business combination. All assets acquired and liabilities assumed in a business combination are measured at their acquisition-date fair values. Acquisition costs are expensed as incurred and restructuring costs that do not meet the definition of a liability at the acquisition date are expensed in periods subsequent to the acquisition date.
	The Company assesses the acquisition date fair values of all tangible assets, identifiable intangibles and assumed liabilities using methods similar to those used by independent appraisers, generally utilizing a discounted cash flow analysis that applies appropriate discount and/or capitalization rates and available market information. Estimates of future cash flows are based on a number of factors, including historical operating results, known and anticipated trends, and market and economic conditions. The fair value of tangible assets of an acquired property considers the value of the property as if it were vacant.
	The Company records above-market and below-market in-place lease values for acquired properties based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of above-market in-place leases and for the initial term plus any extended term for any leases with below-market renewal options. The Company amortizes any recorded above-market or below-market lease values as a reduction or increase, respectively, to rental income over the remaining non-cancelable terms of the respective lease, including any below-market renewal periods.
	The Company estimates the value of tenant origination and absorption costs by considering the estimated carrying costs during hypothetical expected lease up periods, considering current market conditions. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods.
	The Company amortizes the value of tenant origination and absorption costs to depreciation and amortization expense over the remaining non-cancelable term of the leases.
	Estimates of the fair values of the tangible assets, identifiable intangibles and assumed liabilities require the Company to make significant assumptions to estimate market lease rates, property-operating expenses, carrying costs during lease-up periods, discount rates, market absorption periods, and the number of years the property will be held for investment. The use of inappropriate assumptions would result in an incorrect valuation of the Company’s acquired tangible assets, identifiable intangibles and assumed liabilities, which would impact the amount of the Company’s net income.
Real Estate, Impairments of Real Estate and Related Intangible Assets and Liabilities	The Company continually monitors events and changes in circumstances that could indicate that the carrying amounts of its real estate and related intangible assets and liabilities may not be recoverable or realized. When indicators of potential impairment suggest that the carrying value of real estate and related intangible assets and liabilities may not be recoverable, the Company assesses the recoverability by estimating whether the Company will recover the carrying value of the real estate and related intangible assets and liabilities through its undiscounted future cash flows and its eventual disposition. If, based on this analysis, the Company does not believe that it will be able to recover the carrying value of the real estate and related intangible assets and liabilities, the Company would record an impairment loss to the extent that the carrying value exceeds the estimated fair value of the real estate and related intangible assets and liabilities.
Real Estate, Real Estate Held for Sale and Discontinued Operations	The Company generally considers real estate to be “held for sale” when the following criteria are met: (i) management commits to a plan to sell the property, (ii) the property is available for sale immediately, (iii) the property is actively being marketed for sale at a price that is reasonable in relation to its current fair value, (iv) the sale of the property within one year is considered probable and (v) significant changes to the plan to sell are not expected. Real estate that is held for sale and its related assets are classified as “real estate held for sale” and “assets related to real estate held for sale,” respectively, for all periods presented in the accompanying consolidated financial statements. Notes payable and other liabilities related to real estate held for sale are classified as “notes payable related to real estate held for sale” and “liabilities related to real estate held for sale,” respectively, for all periods presented in the accompanying consolidated financial statements. Real estate classified as held for sale is no longer depreciated and is reported at the lower of its carrying value or its estimated fair value less estimated costs to sell. Additionally, with respect to properties that were classified as held for sale in financial statements prior to January 1, 2014, the Company records the operating results as discontinued operations for all periods presented if the operations have been or are expected to be eliminated and the Company will not have any significant continuing involvement in the operations of the property following the sale. Operating results of properties that were disposed of or classified as held for sale in the ordinary course of business during the year ended December 31, 2014 that had not been classified as held for sale in financial statements prior to January 1, 2014 are included in continuing operations on the Company’s consolidated statements of operations.
Change in a Plan to Sell	When real estate is initially considered “held for sale” it is measured at the lower of its depreciated book value or estimated fair value less estimated costs to sell. Changes in the market may compel the Company to decide to reclassify a property that was designated as held for sale to held for investment.  A property that is reclassified from held for sale to held for investment is measured and recorded at the lower of (i) its carrying amount before the property was classified as held for sale, adjusted for any depreciation and amortization expense that would have been recognized had the property been continuously classified as held and used, or (ii) its fair value at the date of the subsequent decision not to sell. Any adjustment to the carrying amount of the property as a result of the reclassification is included in income from continuing operations as an impairment charge on real estate held for investment.
Real Estate Loan Receivable	The Company’s real estate loans receivable are recorded at amortized cost, net of loan loss reserves (if any), and evaluated for impairment at each balance sheet date. The amortized cost of a real estate loan receivable is the outstanding unpaid principal balance, net of unamortized acquisition premiums or discounts and unamortized costs and fees directly associated with the origination or acquisition of the loan.
	As of December 31, 2014, there was no loan loss reserve and the Company did not record any impairment losses related to the real estate loans receivable during the years ended December 31, 2014, 2013 and 2012. However, in the future, the Company may experience losses from its investments in loans receivable requiring the Company to record loan loss reserves. Realized losses on individual loans could be material and significantly exceed any recorded reserves.
	The reserve for loan losses is a valuation allowance that reflects management’s estimate of loan losses inherent in the loan portfolio as of the balance sheet date. The reserve is adjusted through “Provision for loan losses” on the Company’s consolidated statements of operations and is decreased by charge-offs to specific loans when losses are confirmed. The reserve for loan losses may include a portfolio-based component and an asset-specific component.
	An asset-specific reserve relates to reserves for losses on loans considered impaired. The Company considers a loan to be impaired when, based upon current information and events, it believes that it is probable that the Company will be unable to collect all amounts due under the contractual terms of the loan agreement. The Company also considers a loan to be impaired if it grants the borrower a concession through a modification of the loan terms or if it expects to receive assets (including equity interests in the borrower) with fair values that are less than the carrying value of the loan in satisfaction of the loan. A reserve is established when the present value of payments expected to be received, observable market prices, the estimated fair value of the collateral (for loans that are dependent on the collateral for repayment) or amounts expected to be received in satisfaction of a loan are lower than the carrying value of that loan.
	A portfolio-based reserve covers the pool of loans that do not have asset-specific reserves. A provision for loan losses is recorded when available information as of each balance sheet date indicates that it is probable that the pool of loans will incur a loss and the amount of the loss can be reasonably estimated. Required reserve balances for this pool of loans are derived from estimated probabilities of default and estimated loss severities assuming a default occurs. On a quarterly basis, the Company’s management assigns estimated probabilities of default and loss severities to each loan in the portfolio based on factors such as the debt service coverage of the underlying collateral, the estimated fair value of the collateral, the significance of the borrower’s investment in the collateral, the financial condition of the borrower and/or its sponsors, the likelihood that the borrower and/or its sponsors would allow the loan to default, the Company’s willingness and ability to step in as owner in the event of default, and other pertinent factors.
	Failure to recognize impairments would result in the overstatement of earnings and the carrying value of the Company’s real estate loans held for investment. Actual losses, if any, could differ significantly from estimated amounts.
Marketable Securities	The Company classifies its investments in marketable securities as available-for-sale, since the Company may sell them prior to their maturity but does not hold them principally for the purpose of making frequent investments and sales with the objective of generating profits on short-term differences in price. These investments are carried at estimated fair value, with unrealized gains and losses reported in accumulated other comprehensive income (loss). Estimated fair values are generally based on quoted market prices, when available, or on estimates provided by independent pricing sources or dealers who make markets in such securities. In certain circumstances, such as when the market for the securities becomes inactive, the Company may determine it is appropriate to perform an internal valuation of the securities. Upon the sale of a security, the previously recognized unrealized gain (loss) is reversed out of accumulated other comprehensive income (loss) and the actual realized gain (loss) is recognized in earnings.
	On a quarterly basis, the Company evaluates its marketable securities for other-than-temporary impairment. The Company reviews the projected future cash flows from these securities for changes in assumptions due to prepayments, credit loss experience and other factors. If, based on the Company’s quarterly estimate of cash flows, there has been an adverse change in the estimated cash flows from the cash flows previously estimated, the present value of the revised cash flows is less than the present value previously estimated, and the fair value of the securities is less than their amortized cost basis, an other-than-temporary impairment is deemed to have occurred.
	The Company recognizes interest income on marketable securities that are beneficial interests in securitized financial assets and are rated “AA” and above on an accrual basis according to the contractual terms of the securities. Discounts or premiums are amortized to interest income over the life of the investment using the interest method.
	The Company recognizes interest income on marketable securities that are beneficial interests in securitized financial assets that are rated below “AA” using the effective yield method, which requires the Company to periodically project estimated cash flows related to these securities and recognize interest income at an interest rate equivalent to the estimated yield on the security, as calculated using the security’s estimated cash flows and amortized cost basis, or reference amount. Changes in the estimated cash flows are recognized through an adjustment to the yield on the security on a prospective basis. Projecting cash flows for these types of securities requires significant judgment, which may have a significant impact on the timing of revenue recognized on these investments.
	The Company is required to distinguish between other-than-temporary impairments related to credit and other-than-temporary impairments related to other factors (e.g., market fluctuations) on its debt securities that it does not intend to sell and where it is not likely that the Company will be required to sell the security prior to the anticipated recovery of its amortized cost basis. The Company calculates the credit component of the other-than-temporary impairment as the difference between the amortized cost basis of the security and the present value of its estimated cash flows discounted at the yield used to recognize interest income. The credit component will be charged to earnings and the component related to other factors is recorded to other comprehensive income (loss).
Cash and Cash Equivalents	The Company considers all short-term (with an original maturity of three months or less), highly-liquid investments utilized as part of the Company’s cash-management activities to be cash equivalents. Cash equivalents may include cash and short-term investments. Short-term investments are stated at cost, which approximates fair value.
	The Company’s cash and cash equivalents balance exceeds federally insurable limits as of December 31, 2014. The Company monitors the cash balances in its operating accounts and adjusts the cash balances as appropriate; however, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. To date, the Company has experienced no loss or lack of access to cash in its operating accounts.
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 on its variable rate notes payable. The Company records these derivative instruments at fair value on the accompanying consolidated balance sheets. Derivative instruments designated and qualifying as a hedge of the exposure to variability in expected future cash flows or other types of forecasted transactions are considered cash flow hedges. 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 consolidated statements of equity. The changes in fair value for derivative instruments that are not designated as a hedge or that do not meet the hedge accounting criteria are recorded as gain or loss on derivative instruments in the accompanying consolidated statements of operations.
	The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objectives and strategy for undertaking various hedge transactions. This process includes designating all derivative instruments that are part of a hedging relationship to specific forecasted transactions or recognized obligations on the consolidated balance sheets. The Company also assesses and documents, both at the hedging instrument’s inception and on a quarterly basis thereafter, whether the derivative instruments that are used in hedging transactions are highly effective in offsetting changes in cash flows associated with the respective hedged items. When the Company determines that a derivative instrument ceases to be highly effective as a hedge, or that it is probable the underlying forecasted transaction will not occur, the Company discontinues hedge accounting prospectively and reclassifies amounts recorded in accumulated other comprehensive income (loss) to earnings.
	The termination of a cash flow hedge prior to the maturity date may result in a net derivative instrument gain or loss that continues to be reported in accumulated other comprehensive income (loss) and is reclassified into earnings over the period of the original forecasted hedged transaction (i.e., LIBOR based debt service payments) unless it is probable that the original forecasted hedged transaction will not occur by the end of the originally specified time period (as documented at the inception of the hedging relationship) or within an additional two-month period of time thereafter. If it is probable that the hedged forecasted transaction will not occur either by the end of the originally specified time period or within the additional two-month period of time, that derivative instrument gain or loss reported in accumulated other comprehensive income (loss) shall be reclassified into earnings immediately.
Deferred Financing Costs	Deferred financing costs represent commitment fees, loan fees, legal fees and other third-party costs associated with obtaining financing. These costs are amortized over the terms of the respective financing agreements using the interest method. Unamortized deferred financing costs are generally expensed when the associated debt is refinanced or repaid before maturity unless specific rules are met that would allow for the carryover of such costs to the refinanced debt. Costs incurred in seeking financing transactions that do not close are expensed in the period in which it is determined that the financing will not close.
Fair Value Measurements	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.
	When available, the Company utilizes quoted market prices from independent third-party sources to determine fair value and classifies such items in Level 1 or Level 2. In instances where the market for a financial instrument is not active, regardless of the availability of a nonbinding quoted market price, observable inputs might not be relevant and could require the Company to make a significant adjustment to derive a fair value measurement. Additionally, in an inactive market, a market price quoted from an independent third party may rely more on models with inputs based on information available only to that independent third party. When the Company determines the market for a financial instrument owned by the Company to be illiquid or when market transactions for similar instruments do not appear orderly, the Company uses several valuation sources (including internal valuations, discounted cash flow analysis and quoted market prices) and establishes a fair value by assigning weights to the various valuation sources. 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 or 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.
	Changes in assumptions or estimation methodologies can have a material effect on these estimated fair values. In this regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in an immediate settlement of the instrument.
	The Company considers the following factors to be indicators of an inactive market: (i) there are few recent transactions, (ii) price quotations are not based on current information, (iii) price quotations vary substantially either over time or among market makers (for example, some brokered markets), (iv) indexes that previously were highly correlated with the fair values of the asset or liability are demonstrably uncorrelated with recent indications of fair value for that asset or liability, (v) there is a significant increase in implied liquidity risk premiums, yields, or performance indicators (such as delinquency rates or loss severities) for observed transactions or quoted prices when compared with the Company’s estimate of expected cash flows, considering all available market data about credit and other nonperformance risk for the asset or liability, (vi) there is a wide bid-ask spread or significant increase in the bid-ask spread, (vii) there is a significant decline or absence of a market for new issuances (that is, a primary market) for the asset or liability or similar assets or liabilities, and (viii) little information is released publicly (for example, a principal-to-principal market).
	The Company considers the following factors to be indicators of non-orderly transactions: (i) there was not adequate exposure to the market for a period before the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities under current market conditions, (ii) there was a usual and customary marketing period, but the seller marketed the asset or liability to a single market participant, (iii) the seller is in or near bankruptcy or receivership (that is, distressed), or the seller was required to sell to meet regulatory or legal requirements (that is, forced), and (iv) the transaction price is an outlier when compared with other recent transactions for the same or similar assets or liabilities.
Dividend Reinvestment Plan	The Company had a dividend reinvestment plan (the “DRP”) through which its stockholders were able to have their dividends and other distributions reinvested in additional shares of the Company’s common stock. In accordance with the DRP, at such time as the Company announced an updated estimated value per share, participants in the DRP were able to acquire shares of common stock under the plan at a price equal to 95% of the updated estimated value per share of the Company’s common stock. On December 18, 2013, the Company’s board of directors approved an estimated value per share of the Company’s common stock of $10.29 (unaudited) based on the estimated value of the Company’s assets less the estimated value of the Company’s liabilities, divided by the number of shares outstanding, as of September 30, 2013, with the exception of the Company’s real estate properties, which were appraised as of November 30, 2013. Commencing with the January 2, 2014 purchase date, the purchase price per share under the DRP was $9.78. On May 15, 2014, the Company’s board of directors approved the termination of the DRP, which termination was effective May 29, 2014.
Redeemable Common Stock	The Company has a share redemption program that may enable stockholders to sell their shares to the Company in limited circumstances. On May 15, 2014, the Company’s board of directors approved the amendment and restatement of the Company’s share redemption program (the “Amended Share Redemption Program”). The Amended Share Redemption Program provides only for redemptions sought upon a stockholder’s death, “qualifying disability” or “determination of incompetence” (each as defined in the Amended Share Redemption Program, and together with redemptions sought in connection with a stockholders’ death, “special redemptions”) and is limited as further described below.
	From November 16, 2013 until the effectiveness of the Amended Share Redemption Program on June 18, 2014, the terms of the Company’s share redemption program were as follows:
	Pursuant to the share redemption program, there were several limitations on the Company’s ability to redeem shares under the program:
	•	Unless the shares were being redeemed in connection with a special redemption, the Company could not redeem shares unless the stockholder has held the shares for one year.
	•	During any calendar year, the Company could redeem only the number of shares that the Company could purchase with the amount of net proceeds from the sale of shares under the Company’s dividend reinvestment plan during the prior calendar year, provided that the Company could not redeem more than $3.0 million of shares in the aggregate each month, excluding shares redeemed in connection with special redemptions; provided, however, the Company could increase the funding available for the redemption of shares pursuant to the Company’s share redemption program upon ten business days’ notice to its stockholders. The Company could provide notice by including such information (a) in a Current Report on Form 8-K or in the Company’s annual or quarterly reports, all publicly filed with the Securities and Exchange Commission or (b) in a separate mailing to the Company’s stockholders.
	•	During any calendar year, the Company could redeem no more than 5% of the weighted-average number of shares outstanding during the prior calendar year.
	•	The Company had no obligation to redeem shares if the redemption would violate the restrictions on distributions under Maryland General Corporation Law, as amended from time to time, which prohibits distributions that would cause a corporation to fail to meet statutory tests of solvency.
	In connection with the amendments to the share redemption program that became effective on November 16, 2013, the Company’s board of directors approved additional funding for the redemption of shares pursuant to the share redemption program as follows: once the Company had redeemed $3.0 million of shares in the aggregate in any month (excluding special redemptions), then an additional $20.0 million of funds in the aggregate was available for the redemption of shares on redemption dates commencing with the November 29, 2013 redemption date (excluding special redemptions) until such $20.0 million of funds was exhausted; provided that, in no event could the Company redeem, during any calendar year, more shares than the number of shares that the Company could purchase with the amount of net proceeds from the sale of shares under the Company’s dividend reinvestment plan during the prior calendar year. The other limitations of the Company’s share redemption program remained in full force and effect. As of March 31, 2014, the Company had exhausted all $20.0 million of these funds.
	On March 7, 2014, the Company’s board of directors approved additional funding for the redemption of shares pursuant to the share redemption program. Once the Company had redeemed $3.0 million of shares in the aggregate in any month (excluding shares redeemed in connection with special redemptions), then an additional $30.0 million of funds in the aggregate was available for the redemption of shares on redemption dates commencing with the March 31, 2014 redemption date (excluding special redemptions) until such $30.0 million of funds was exhausted; provided that, in no event could the Company redeem, during any calendar year, more shares than the number of shares that the Company could purchase with the amount of net proceeds from the sale of shares under its dividend reinvestment plan during the prior calendar year. The other limitations of the Company’s share redemption program remained in full force and effect.
	Pursuant to the share redemption program, redemptions made in connection with special redemptions were made at a price per share equal to the most recent estimated value per share of the Company’s common stock as of the applicable redemption date. The prices at which the Company redeemed all other shares eligible for redemption is as follows:
	•	For those shares held by the redeeming stockholder for at least one year, 92.5% of the Company’s most recent estimated value per share as of the applicable redemption date;
	•	For those shares held by the redeeming stockholder for at least two years, 95.0% of the Company’s most recent estimated value per share as of the applicable redemption date;
	•	For those shares held by the redeeming stockholder for at least three years, 97.5% of the Company’s most recent estimated value per share as of the applicable redemption date; and
	•	For those shares held by the redeeming stockholder for at least four years, 100% of the Company’s most recent estimated value per share as of the applicable redemption date.
	Upon effectiveness of the Amended Share Redemption Program on June 18, 2014, the terms of the share redemption program were as follows:
	The Company’s board of directors amended and restated the Company’s share redemption program to provide only for redemptions sought in connection with a special redemption. During each calendar year, such special redemptions are limited to an annual dollar amount determined by the board of directors, which may be reviewed during the year and increased or decreased upon ten business days’ notice to the Company’s stockholders. The Company may provide notice by including such information (a) in a Current Report on Form 8-K or in the Company’s annual or quarterly reports, all publicly filed with the Securities and Exchange Commission or (b) in a separate mailing to the stockholders.
	Such redemptions are also subject to other limitations described in the Company’s Amended Share Redemption Program, including:
	•	During any calendar year, the Company may redeem no more than 5% of the weighted-average number of shares outstanding during the prior calendar year.
	•	The Company has no obligation to redeem shares if the redemption would violate the restrictions on distributions under Maryland General Corporation Law, as amended from time to time, which prohibits distributions that would cause a corporation to fail to meet statutory tests of solvency.
	Commencing with the June 2014 redemption date, the dollar amount limitation for special redemptions for the remainder of calendar year 2014 was $10.0 million in the aggregate, as may be reviewed and adjusted from time to time by the Company’s board of directors. Based on historical redemption data, the Company’s board of directors believed that the $10.0 million redemption limitation for the remainder of calendar year 2014 would be sufficient for these special redemptions. On December 2, 2014, the Company’s board of directors approved the dollar amount limitation for special redemptions for calendar year 2015 of $10.0 million in the aggregate, as may be reviewed and adjusted from time to time by the Company’s board of directors. Based on historical redemption data, the Company’s board of directors believes that the $10.0 million redemption limitation for calendar year 2015 will be sufficient for these special redemptions.
	There were no other changes to the terms of special redemptions, and special redemptions will continue to be made at a price per share equal to the most recent estimated value per share of the Company’s common stock as of the applicable redemption date. The Company currently does not expect to make ordinary redemptions in the future.
	On December 18, 2013, the Company’s board of directors approved an estimated value per share of the Company’s common stock of $10.29 (unaudited) based on the estimated value of the Company’s assets less the estimated value of the Company’s liabilities, divided by the number of shares outstanding, as of September 30, 2013, with the exception of the Company’s real estate properties, which were appraised as of November 30, 2013. This estimated value per share was used to calculate the redemption price commencing with the December 2013 redemption date, which was December 31, 2013.
	On September 22, 2014, the Company’s board of directors approved an estimated value per share of the Company’s common stock of $6.05 (unaudited) based on the estimated value of Company’s assets less the estimated value of the Company’s liabilities, divided by the number of shares outstanding, all as of June 30, 2014, adjusted for the impact of the $4.50 special distribution declared subsequent to June 30, 2014 and paid on September 23, 2014. The change in the redemption price was effective for the September 2014 redemption date, which was September 30, 2014.
	On December 4, 2014, the Company’s board of directors approved an estimated value per share of the Company’s common stock of $5.86 (unaudited) based on the estimated value of the Company’s assets less the estimated value of the Company’s liabilities, divided by the number of shares outstanding, all as of September 30, 2014. The change in the redemption price was effective for the December 2014 redemption date, which was December 31, 2014, and is effective until the estimated value per share is updated.
	The estimated value per share was based upon the recommendation and valuation prepared by the Advisor. As with any valuation methodology, the methodologies used are based upon a number of estimates and assumptions that may not be accurate or complete. Different parties with different assumptions and estimates could derive a different estimated value per share, and these differences could be significant. The estimated value per share is not audited and does not represent the fair value of the Company’s assets and liabilities according to GAAP, nor does it represent a liquidation value of the Company’s assets and liabilities or the amount the Company’s shares of common stock would trade at on a national securities exchange. The estimated value per share does not reflect a discount for the fact that the Company is externally managed, nor does it reflect a real estate portfolio premium/discount versus the sum of the individual property values. The estimated value per share also does not take into account estimated disposition costs and fees for real estate properties that are not under contract to sell, debt prepayment penalties or swap breakage fees that could apply upon the prepayment of certain of the Company’s debt obligations or termination of swap related agreements or the impact of restrictions on the assumption of debt.
	The value of the Company’s shares will fluctuate over time in response to developments related to individual assets in the portfolio and the management of those assets and in response to the real estate and finance markets. The Company currently expects to utilize the Advisor and/or an independent valuation firm to update the estimated value per share in December of each year, or more frequently, in accordance with recommended Practice Guideline 2013-01, Valuations of Publicly Registered Non-Listed REITs, issued by the Investment Program Association (“IPA”) in April 2013.
	The Company’s board of directors may amend, suspend or terminate the share redemption program with 30 days’ notice to its stockholders, provided that the Company may increase or decrease the funding available for the redemption of shares under the program upon ten business days’ notice to stockholders. The Company may provide this notice by including such information in a Current Report on Form 8-K or in the Company’s annual or quarterly reports, all publicly filed with the SEC, or by a separate mailing to its stockholders.
	The Company records amounts that are redeemable under the share redemption program as redeemable common stock in the accompanying consolidated balance sheets because the shares are mandatorily redeemable at the option of the holder and therefore their redemption is outside the control of the Company. Pursuant to the share redemption program, beginning in 2014, the maximum amount redeemable under the Company’s share redemption program is limited to an annual dollar amount determined by Company’s board of directors, as described above. However, because the amounts that can be redeemed in future periods are determinable and only contingent on an event that is likely to occur (e.g., the passage of time), the Company presents the amounts available for future redemptions in future periods as redeemable common stock in the accompanying consolidated balance sheets.
	The Company classifies financial instruments that represent a mandatory obligation of the Company to redeem shares as liabilities. The Company’s redeemable common shares are contingently redeemable at the option of the holder. When the Company determines it has a mandatory obligation to redeem shares under the share redemption program, it will reclassify such obligations from temporary equity to a liability based upon their respective settlement values.
	The Company limits the dollar value of shares that may be redeemed under the share redemption program as described above. For the year ended December 31, 2014, the Company redeemed 4,457,374 shares sold in the Offering for $44.7 million, which represented all redemption requests received in good order and eligible for redemption through the December 2014 redemption date.
Related Party Transactions	The Company has entered into the Advisory Agreement with the Advisor and the Dealer Manager Agreement with the Dealer Manager. These agreements entitled the Advisor and/or the Dealer Manager to specified fees upon the provision of certain services with regard to the Offering and entitle the Advisor to specified fees upon the provision of certain services with regard to the investment of funds in real estate and real estate-related investments, the management of those 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 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 (“AIP 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. and KBS Strategic Opportunity REIT II, Inc. and anticipate that they will serve as the Advisor and Dealer Manager, respectively, for KBS Growth & Income REIT, Inc.
	The Company records all related party fees as incurred, subject to any limitations described in the Advisory Agreement.
Related Party Transactions, Acquisition and Origination Fees	The Company paid the Advisor an acquisition fee equal to 0.75% of the cost of investments acquired, including acquisition expenses and any debt attributable to such investments. With respect to investments in and originations of loans, the Company paid an origination fee equal to 1% of the amount funded by the Company to acquire or originate mortgage, mezzanine, bridge or other loans, including any expenses related to such investments and any debt the Company used to fund the acquisition or origination of these loans. The Company did not pay an acquisition fee with respect to investments in loans.
Related Party Transactions, Asset Management Fee	With respect to investments in real estate, the Company pays the Advisor a monthly asset management fee equal to one-twelfth of 0.75% of the amount paid or allocated to acquire the investment, plus the cost of any subsequent development, construction or improvements to the property. This amount includes any portion of the investment that was debt financed and is inclusive of acquisition fees and expenses related thereto. In the case of investments made through joint ventures, the asset management fee will be determined based on the Company’s proportionate share of the underlying investment.
	With respect to investments in loans and any investments other than real estate, the Company pays the Advisor a monthly fee calculated, each month, as one-twelfth of 0.75% of the lesser of (i) the amount paid or allocated to acquire or fund the loan or other investment (which amount includes any portion of the investment that was debt financed and is inclusive of acquisition or origination fees and expenses related thereto) and (ii) the outstanding principal amount of such loan or other investment, plus the acquisition or origination fees and expenses related to the acquisition or funding of such investment, as of the time of calculation.
	With respect to an investment that has suffered an impairment in value, reduction in cash flow or other negative circumstances, such investment may either be excluded from the calculation of the asset management fee described above or included in such calculation at a reduced value that is recommended by the Advisor and the Company’s management and then approved by a majority of the Company’s independent directors, and this change in the fee will be applicable to an investment upon the earlier to occur of the date on which (i) such investment is sold, (ii) such investment is surrendered to a person other than the Company, its direct or indirect wholly owned subsidiary or a joint venture or partnership in which the Company has an interest, (iii) the Advisor determines that it will no longer pursue collection or other remedies related to such investment, or (iv) the Advisor recommends a revised fee arrangement with respect to such investment. As of December 31, 2014, the Company has not determined to calculate the asset management fee at an adjusted value for any investments or to exclude any investments from the calculation of the asset management fee.
Related Party Transactions, Disposition Fee	For substantial assistance in connection with the sale of properties or other investments, the Company pays the Advisor or its affiliates 1.0% of the contract sales price of each property or other investment sold; provided, however, in no event may the disposition fees paid to Advisor, its affiliates and unaffiliated third parties exceed 6.0% of the contract sales price.
Income Taxes	The Company has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended. To qualify as a REIT, the Company must meet certain organizational and operational requirements, including a requirement to distribute at least 90% of the Company’s annual REIT taxable income to stockholders (which is computed without regard to the dividends-paid deduction or net capital gain and which does not necessarily equal net income as calculated in accordance with GAAP). As a REIT, the Company generally will not be subject to federal income tax on income that it distributes as dividends to its stockholders. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income tax on its taxable income at regular corporate income tax rates and generally will not be permitted to qualify for treatment as a REIT for federal income tax purposes for the four taxable years following the year during which qualification is lost, unless the Internal Revenue Service grants the Company relief under certain statutory provisions. Such an event could materially and adversely affect the Company’s net income and net cash available for distribution to stockholders. However, the Company believes that it is organized and operates in such a manner as to qualify for treatment as a REIT.
	The Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. Neither the Company nor its subsidiaries have been assessed interest or penalties by any major tax jurisdictions. The Company’s evaluations were performed for the tax years ended December 31, 2014, 2013 and 2012. As of December 31, 2014, returns for the calendar years 2010 through 2013 remain subject to examination by major tax jurisdictions.
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 years ended December 31, 2014, 2013 and 2012, respectively.
	Distributions declared per common share were $5.066 in the aggregate for the year ended December 31, 2014. Distributions declared per common share assumes each share was issued and outstanding each day that was a record date for distributions during the year ended December 31, 2014. These distributions declared consisted of the following:
	•	The Company’s board of directors declared distributions per common share based on daily record dates for each day during the period from January 1, 2014 through August 31, 2014. Each day during the period was a record date for distributions and distributions were calculated at a rate of $0.00178082 per share per day.
	•	The Company’s board of directors declared special distributions in the amount of $3.75, $0.30 and $0.45 per share on the outstanding shares of the Company’s common stock on July 8, 2014, August 5, 2014 and August 29, 2014, respectively, for an aggregate amount of $4.50 per share of common stock, to stockholders of record as of the close of business on September 15, 2014.
	•	On August 29, 2014, the Company’s board of directors declared September 2014 and October 2014 distributions in the amounts of $0.03277397 and $0.03386644 per share of common stock, respectively, to stockholders of record as of the close of business on September 26, 2014 and October 29, 2014, respectively.
	•	On November 10, 2014, the Company’s board of directors declared a November 2014 distribution in the amount of $0.03277397 per share of common stock to stockholders of record as of the close of business on November 26, 2014.
	•	On December 2, 2014, the Company’s board of directors declared a December 2014 distribution in the amount of $0.03386644 per share of common stock to stockholders of record as of the close of business on December 29, 2014.
	Distributions declared per common share were $0.704 and $0.650 for the years ended December 31, 2013 and 2012, respectively. Distributions declared per common share assumes each share was issued and outstanding each day during the years ended December 31, 2013 and 2012. For each day that was a record date for distributions during the years ended December 31, 2013 and 2012, distributions were based on a daily record dates and calculated at a rate of $0.00178082 per share per day. Each day during the periods from January 1, 2012 through February 28, 2012 and March 1, 2012 through December 31, 2013 was a record date for distributions. Additionally, the Company’s board of directors declared a distribution in the amount of $0.05416667 per share of common stock to stockholders of record as of the close of business on February 4, 2013.
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 13, “Segment Information.”
Square Footage, Occupancy and Other Measures	Square footage, occupancy and other measures used to describe real estate and real estate-related investments included in these Notes to Consolidated Financial Statements are presented on an unaudited basis.
Recently Issued Accounting Standards Update	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360):  Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU No. 2014-08”).  ASU No. 2014-08 limits discontinued operations reporting to disposals of components of an entity that represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results when any of the following occurs: a) the component of an entity or group of components of an entity meets the criteria to be classified as held for sale; b) the component of an entity or group of components of an entity is disposed of by sale; or c) the component of an entity or group of components of an entity is disposed of other than by sale.  ASU No. 2014-08 also requires additional disclosures about discontinued operations.  ASU No. 2014-08 is effective for reporting periods beginning after December 15, 2014.  Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company early adopted ASU No. 2014-08 for the reporting period beginning January 1, 2014.  As a result of the adoption of ASU No. 2014-08, results of operations for properties that are classified as held for sale in the ordinary course of business on or subsequent to January 1, 2014 would generally be included in continuing operations on the Company’s consolidated statements of operations, to the extent such disposals did not meet the criteria for classification as a discontinued operation described above. Additionally, any gain or loss on sale of real estate that does not meet the criteria for classification as a discontinued operation would be included in income from continuing operations on the consolidated statements of operations.
	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.  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 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 2015-01 to have a significant impact on its financial statements.
