Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Quarterly Presentation The accompanying unaudited consolidated financial statements and related notes of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and note disclosures normally included in the consolidated financial statements prepared under U.S. GAAP have been condensed or omitted. In the opinion of management, all adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations and cash flows have been included and are of a normal and recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 , which was filed with the Securities and Exchange Commission (the “SEC”). Principles of Consolidation The consolidated financial statements include the accounts of the Company, the Operating Partnership and their consolidated subsidiaries. The Company consolidates variable interest entities (“VIE”) where the Company is the primary beneficiary and voting interest entities which are generally majority owned or otherwise controlled by the Company. All significant intercompany balances are eliminated in consolidation. Variable Interest Entities A VIE is an entity that lacks one or more of the characteristics of a voting interest entity. A VIE is defined as an entity in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The determination of whether an entity is a VIE includes both a qualitative and quantitative analysis. The Company bases its qualitative analysis on its review of the design of the entity, its organizational structure including decision-making ability and relevant financial agreements and the quantitative analysis on the forecasted cash flow of the entity. The Company reassesses its initial evaluation of an entity as a VIE upon the occurrence of certain reconsideration events. A VIE must be consolidated only by its primary beneficiary, which is defined as the party who, along with its affiliates and agents has both the: (i) power to direct the activities that most significantly impact the VIE’s economic performance; and (ii) obligation to absorb the losses of the VIE or the right to receive the benefits from the VIE, which could be significant to the VIE. The Company determines whether it is the primary beneficiary of a VIE by considering qualitative and quantitative factors, including, but not limited to: which activities most significantly impact the VIE’s economic performance and which party controls such activities; the amount and characteristics of its investment; the obligation or likelihood for the Company or other interests to provide financial support; consideration of the VIE’s purpose and design, including the risks the VIE was designed to create and pass through to its variable interest holders and the similarity with and significance to the business activities of the Company and the other interests. The Company reassesses its determination of whether it is the primary beneficiary of a VIE each reporting period. Significant judgments related to these determinations include estimates about the current and future fair value and performance of investments held by these VIEs and general market conditions. The Company evaluates its investments and financings, including investments in unconsolidated ventures and securitization financing transactions to determine whether they are a VIE. The Company analyzes new investments and financings, as well as reconsideration events for existing investments and financings, which vary depending on type of investment or financing. As of September 30, 2015 , the Company identified one VIE related to its securities investments. The VIE has a carrying value of $48.5 million as of September 30, 2015 . The Company’s maximum exposure to loss as of September 30, 2015 would not exceed the carrying value of its investment. Based on management’s analysis, the Company determined that it does not currently or potentially hold a significant interest in this VIE and, therefore, is not the primary beneficiary. Accordingly, the VIE is not consolidated in the Company’s financial statements as of September 30, 2015 . The Company did not provide financial support to its unconsolidated VIE during the nine months ended September 30, 2015 . As of September 30, 2015 , there were no explicit arrangements or implicit variable interests that could require the Company to provide financial support to its unconsolidated VIE. An affiliate of the Sponsor is named special servicer of the VIE. Voting Interest Entities A voting interest entity is an entity in which the total equity investment at risk is sufficient to enable it to finance its activities independently and the equity holders have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the losses of the entity and the right to receive the residual returns of the entity. The usual condition for a controlling financial interest in a voting interest entity is ownership of a majority voting interest. If the Company has a majority voting interest in a voting interest entity, the entity will generally be consolidated. The Company does not consolidate a voting interest entity if there are substantive participating rights by other parties and/or kick-out rights by a single party. The Company performs on-going reassessments of whether entities previously evaluated under the voting interest framework have become VIEs, based on certain events, and therefore subject to the VIE consolidation framework. Investments in Unconsolidated Ventures A non-controlling, unconsolidated ownership interest in an entity may be accounted for using the equity method, at fair value or the cost method. Under the equity method, the investment is adjusted each period for capital contributions and distributions and its share of the entity’s net income (loss). Capital contributions, distributions and net income (loss) of such entities are recorded in accordance with the terms of the governing documents. An allocation of net income (loss) may differ from the stated ownership percentage interest in such entity as a result of a preferred return and allocation formula, if any, as described in such governing documents. Equity method investments are recognized using a cost accumulation model in which the investment is recognized based on the cost to the investor, which includes acquisition fees. The Company records as an expense certain acquisition costs and fees associated with consolidated investments deemed to be business combinations and capitalizes these costs for investments deemed to be acquisitions of an asset, including an equity method investment. The Company may account for an investment in an unconsolidated entity at fair value by electing the fair value option. The Company elected the fair value option for PE Investments. The Company records the change in fair value for its share of the projected future cash flow of such investments from one period to another in equity in earnings (losses) from unconsolidated ventures in the consolidated statements of operations. Any change in fair value attributed to market related assumptions is considered unrealized gain (loss). The Company may account for an investment that does not qualify for equity method accounting or for which the fair value option was not elected using the cost method if the Company determines the investment in the unconsolidated entity is insignificant. Under the cost method, equity in earnings is recorded as dividends are received to the extent they are not considered a return of capital, which is recorded as a reduction of cost of the investment. Non-controlling Interests A non-controlling interest in a consolidated subsidiary is defined as the portion of the equity (net assets) in a subsidiary not attributable, directly or indirectly, to the Company. A non-controlling interest is required to be presented as a separate component of equity on the consolidated balance sheets and presented separately as net income (loss) and other comprehensive income (loss) (“OCI”) attributable to controlling and non-controlling interests. An allocation to a non-controlling interest may differ from the stated ownership percentage interest in such entity as a result of a preferred return and allocation formula, if any, as described in such governing documents. Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that could affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates and assumptions. Reclassifications Certain prior period amounts have been reclassified in the consolidated financial statements to conform to current period presentation. Comprehensive Income (Loss) The Company reports consolidated comprehensive income (loss) in separate statements following the consolidated statements of operations. Comprehensive income (loss) is defined as the change in equity resulting from net income (loss) and OCI. The only component of OCI is unrealized gain (loss) on CRE securities available for sale for which the fair value option was not elected. Fair Value Option The fair value option provides an election that allows a company to irrevocably elect fair value for certain financial assets and liabilities on an instrument-by-instrument basis at initial recognition. The Company will generally not elect the fair value option for its assets and liabilities. However, the Company has elected the fair value option for PE Investments. Any change in fair value for assets and liabilities for which the election is made is recognized in earnings. Real Estate Debt Investments CRE debt investments are generally intended to be held to maturity and, accordingly, are carried at cost, net of unamortized loan fees, premium, discount and unfunded commitments. CRE debt investments that are deemed to be impaired are carried at amortized cost less a loan loss reserve, if deemed appropriate, which approximates fair value. CRE debt investments where the Company does not have the intent to hold the loan for the foreseeable future or until its expected payoff are classified as held for sale and recorded at the lower of cost or estimated value. Operating Real Estate Operating real estate is carried at historical cost less accumulated depreciation. Ordinary repairs and maintenance are expensed as incurred. Major replacements and betterments which improve or extend the life of the asset are capitalized and depreciated over their useful life. The Company follows the purchase method for an acquisition of operating real estate, where the purchase price is allocated to tangible assets such as land, building, tenant and land improvements and other identified intangibles. Costs directly related to an acquisition deemed to be a business combination are expensed and included in transaction costs in the consolidated statements of operations. Real Estate Securities The Company classifies its CRE securities investments as available for sale on the acquisition date, which are carried at fair value. Unrealized gains (losses) are recorded as a component of accumulated OCI in the consolidated statements of equity. However, the Company may elect the fair value option for certain of its available for sale securities, and as a result, any unrealized gains (losses) on such securities are recorded in unrealized gain (loss) on investments and other in the consolidated statements of operations. As of September 30, 2015 , the Company did not have any CRE securities investments for which it elected the fair value option. Acquisition Fees and Expenses The total of all acquisition fees and expenses for an investment, including acquisition fees to the Advisor, cannot exceed, in the aggregate, 6.0% of the contract purchase price of such investment unless such excess is approved by a majority of the directors, including independent directors. An acquisition fee incurred related to an equity investment will generally be expensed as incurred. An acquisition fee paid to the Advisor related to the acquisition of an equity or debt investment in an unconsolidated joint venture is included in investments in unconsolidated ventures on the consolidated balance sheets. An acquisition fee paid to the Advisor related to the origination or acquisition of debt investments is included in debt investments, net on the consolidated balance sheets and is amortized to interest income over the life of the investment using the effective interest method. The Company records as an expense certain acquisition costs and fees associated with transactions deemed to be business combinations in which it consolidates the asset and capitalizes these costs for transactions deemed to be acquisitions of an asset, including an equity investment. Revenue Recognition Real Estate Debt Investments Interest income is recognized on an accrual basis and any related premium, discount, origination costs and fees are amortized over the life of the investment using the effective interest method. The amortization is reflected as an adjustment to interest income in the consolidated statements of operations. The amortization of a premium or accretion of a discount is discontinued if such loan is reclassified to held for sale. Operating Real Estate Rental and other income from operating real estate is derived from leasing of space to various types of tenants. The leases are for fixed terms of varying length and generally provide for annual rentals and expense reimbursements to be paid in monthly installments. Rental income from leases is recognized on a straight-line basis over the term of the respective leases. The excess of rent recognized over the amount contractually due pursuant to the underlying leases is included in receivables on the consolidated balance sheets. Real Estate Securities Interest income is recognized using the effective interest method with any premium or discount amortized or accreted through earnings based on expected cash flow through the expected maturity date of the security. Changes to expected cash flow may result in a change to the yield which is then applied retrospectively for high-credit quality securities that cannot be prepaid or otherwise settled in such a way that the holder would not recover substantially all of the investment or prospectively for all other securities to recognize interest income. Credit Losses and Impairment on Investments Real Estate Debt Investments Loans are considered impaired when, based on current information and events, it is probable that the Company will not be able to collect principal and interest amounts due according to the contractual terms. The Company assesses the credit quality of the portfolio and adequacy of loan loss reserves on a quarterly basis or more frequently as necessary. Significant judgment of the Company is required in this analysis. The Company considers the estimated net recoverable value of the loan as well as other factors, including but not limited to the fair value of any collateral, the amount and the status of any senior debt, the quality and financial condition of the borrower and the competitive situation of the area where the underlying collateral is located. Because this determination is based on projections of future economic events, which are inherently subjective, the amount ultimately realized may differ materially from the carrying value as of the balance sheet date. If upon completion of the assessment, the estimated fair value of the underlying collateral is less than the net carrying value of the loan, a loan loss reserve is recorded with a corresponding charge to provision for loan losses. The loan loss reserve for each loan is maintained at a level that is determined to be adequate by management to absorb probable losses. Income recognition is suspended for a loan at the earlier of the date at which payments become 90 -days past due or when, in the opinion of the Company, a full recovery of income and principal becomes doubtful. When the ultimate collectability of the principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the principal of an impaired loan is not in doubt, contractual interest is recorded as interest income when received, under the cash basis method until an accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. A loan is written off when it is no longer realizable and/or legally discharged. Operating Real Estate The Company’s real estate portfolio is reviewed on a quarterly basis, or more frequently as necessary, to assess whether there are any indicators that the value of its operating real estate may be impaired or that its carrying value may not be recoverable. A property’s value is considered impaired if the Company’s estimate of the aggregate expected future undiscounted cash flow generated by the property is less than the carrying value. In conducting this review, the Company considers U.S. macroeconomic factors, real estate sector conditions and asset specific and other factors. To the extent an impairment has occurred, the loss is measured as the excess of the carrying value of the property over the estimated fair value and recorded in impairment on operating real estate in the consolidated statements of operations. An allowance for a doubtful account for a tenant receivable is established based on a periodic review of aged receivables resulting from estimated losses due to the inability of tenants to make required rent and other payments contractually due. Additionally, the Company establishes, on a current basis, an allowance for future tenant credit losses on unbilled rent receivable based on an evaluation of the collectability of such amounts. Investments in Unconsolidated Ventures The Company reviews its investments in unconsolidated ventures for which the Company did not elect the fair value option on a quarterly basis, or more frequently as necessary, to assess whether there are any indicators that the value may be impaired or that its carrying value may not be recoverable. An investment is considered impaired if the projected net recoverable amount over the expected holding period is less than the carrying value. In conducting this review, the Company considers U.S. macroeconomic factors, including real estate sector conditions, together with investment specific and other factors. To the extent an impairment has occurred and is considered to be other than temporary, the loss is measured as the excess of the carrying value of the investment over the estimated fair value and recorded in provision for loss on equity investment in the consolidated statements of operations. Real Estate Securities CRE securities for which the fair value option is elected are not evaluated for other-than-temporary impairment (“OTTI”) as any change in fair value is recorded in the consolidated statements of operations. Realized losses on such securities are reclassified to realized gain (loss) on investments and other as losses occur. CRE securities for which the fair value option is not elected are evaluated for OTTI quarterly. Impairment of a security is considered to be other-than-temporary when: (i) the holder has the intent to sell the impaired security; (ii) it is more likely than not the holder will be required to sell the security; or (iii) the holder does not expect to recover the entire amortized cost of the security. When a CRE security has been deemed to be other-than-temporarily impaired due to (i) or (ii), the security is written down to its fair value and an OTTI is recognized in the consolidated statements of operations. In the case of (iii), the security is written down to its fair value and the amount of OTTI is then bifurcated into: (a) the amount related to expected credit losses; and (b) the amount related to fair value adjustments in excess of expected credit losses. The portion of OTTI related to expected credit losses is recognized in the consolidated statements of operations. The remaining OTTI related to the valuation adjustment is recognized as a component of accumulated OCI in the consolidated statements of equity. The portion of OTTI recognized through earnings is accreted back to the amortized cost basis of the security through interest income, while amounts recognized through OCI are amortized over the life of the security with no impact on earnings. CRE securities which are not high-credit quality are considered to have an OTTI if the security has an unrealized loss and there has been an adverse change in expected cash flow. The amount of OTTI is then bifurcated as discussed above. As of September 30, 2015 , the Company did not have any OTTI recorded on its CRE securities. Derivatives Derivatives are used to manage exposure to interest rate risk. All cash settlements and any change in fair value are recorded in interest income in the consolidated statements of operations. As of September 30, 2015 , the Company had one interest rate floor as a hedge related to its floating-rate investments, maturing in October 2015 with a fair value of $0.3 million and a notional amount of $225.0 million . Derivatives are generally valued using a third-party pricing service. These quotations are not adjusted and are based on observable inputs that can be validated, and as such, are classified as Level 2 of the fair value hierarchy. Refer to Note 12 for further disclosure. The interest rate floor is included in deferred costs and other assets, net on the consolidated balance sheet as of September 30, 2015 . Organization and Offering Costs The Prior Advisor, or its affiliates, was entitled to receive reimbursement for costs paid on behalf of the Company in connection with the Offering. The Company was obligated to reimburse the Prior Advisor for organization and offering costs to the extent the aggregate of selling commissions, dealer manager fees and other organization and offering costs do not exceed 15.0% of gross offering proceeds from the Total Primary Offering. The Prior Advisor initially expected reimbursable organization and offering costs would not exceed $15.0 million , or 1.5% of the total proceeds available to be raised from the Total Primary Offering. Based on gross proceeds raised of $1,072.9 million from the Total Primary Offering, the Company incurred reimbursable organization and offering costs, excluding selling commissions and dealer manager fees, of 1.0% , which was less than the 1.5% expected. The Company recorded organization and offering costs each period based upon an allocation determined by the expectation of total organization and offering costs to be reimbursed. Organization costs were recorded as an expense in general and administrative expenses in the consolidated statements of operations and offering costs were recorded as a reduction to equity. Income Taxes The Company elected to be taxed as a REIT and to comply with the related provisions of the Internal Revenue Code beginning in its taxable year ended December 31, 2010. Accordingly, the Company will generally not be subject to U.S. federal income tax to the extent of its distributions to stockholders as long as certain asset, income and share ownership tests are met. To maintain its qualification as a REIT, the Company must annually distribute at least 90% of its REIT taxable income to its stockholders and meet certain other requirements. The Company may also be subject to certain state, local and franchise taxes. Under certain circumstances, federal income and excise taxes may be due on its undistributed taxable income. If the Company were to fail to meet these requirements, it would be subject to U.S. federal income tax, which could have a material adverse impact on its results of operations and amounts available for distributions to its stockholders. The Company believes that all of the criteria to maintain the Company’s REIT qualification have been met for the applicable periods, but there can be no assurance that these criteria will continue to be met in subsequent periods. Current and deferred taxes are recorded on the portion of earnings (losses) recognized by the Company with respect to its interest in taxable REIT subsidiaries. Deferred income tax assets and liabilities are calculated based on temporary differences between the Company’s U.S. GAAP consolidated financial statements and the federal, state, local and foreign tax basis of assets and liabilities as of the consolidated balance sheet date. The Company evaluates the realizability of its deferred tax assets (e.g., net operating loss and capital loss carryforwards) and recognizes a valuation allowance if, based on the available evidence, it is more likely than not that some portion or all of its deferred tax assets will not be realized. When evaluating the realizability of its deferred tax assets, the Company considers estimates of expected future taxable income, existing and projected book/tax differences, tax planning strategies available and the general and industry specific economic outlook. This realizability analysis is inherently subjective, as it requires the Company to forecast its business and general economic environment in future periods. Changes in estimate of deferred tax asset realizability, if any, are included in provision for income tax expense included in income tax benefit (expense) in the consolidated statements of operations. The Company recorded an income tax benefit of $1.2 million and expense of $1.1 million for the three months ended September 30, 2015 and 2014 , respectively. The Company recorded an income tax expense of $0.4 million and $2.6 million for the nine months ended September 30, 2015 and 2014 , respectively. Other Refer to Note 2 of the consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 for further disclosure of the Company’s significant accounting policies. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting update requiring a company to recognize as revenue the amount of consideration it expects to be entitled to in connection with the transfer of promised goods or services to customers. The accounting standard update will replace most of the existing revenue recognition guidance currently promulgated by U.S. GAAP. In July 2015, the FASB decided to delay the effective date of the new revenue standard by one year. The effective date of the new revenue standard for the Company will be January 1, 2018. The Company is in the process of evaluating the impact, if any, of the update on its consolidated financial position, results of operations and financial statement disclosures. In February 2015, the FASB issued updated guidance that changes the rules regarding consolidation. The pronouncement eliminates specialized guidance for limited partnerships and similar legal entities and removes the indefinite deferral for certain investment funds. The new guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, with early adoption permitted. The Company is currently assessing the impact of the guidance on the Company’s consolidated financial position, results of operations and financial statement disclosures. In April 2015, the FASB issued an accounting update changing the presentation of financing costs in financial statements. Under the new guidance, an entity would present these costs in the balance sheet as a direct deduction from the related liability rather than as an asset. Amortization of the costs would continue to be reported as interest expense. The new guidance is effective for annual periods and interim periods beginning after December 15, 2015, with early adoption permitted. The Company is currently assessing the impact of the guidance on the Company’s consolidated financial position, results of operations and financial statement disclosures. In September 2015, the FASB issued updated guidance that eliminates the requirement that an acquirer in a business combination account for measurement-period adjustments retrospectively. Under the new guidance, an acquirer will recognize a measurement-period adjustment during the period in which it determines the amount of the adjustment. The new guidance is effective for annual periods and interim periods beginning after December 15, 2015, with early adoption permitted. The Company adopted this guidance in the third quarter 2015. See “Note 4. Operating Real Estate” for more information regarding adjustments to provisional amounts that occurred during the three months ended September 30, 2015. |
