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, 2016 , 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 (“VIEs”), if any, 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, if any, to determine whether each investment or financing is 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 June 30, 2017 , the Company has identified certain consolidated and unconsolidated VIEs. Assets of each of the VIEs, other than the Operating Partnership, may only be used to settle obligations of the respective VIE. Creditors of each of the VIEs have no recourse to the general credit of the Company. Consolidated VIEs The most significant consolidated VIEs are the Operating Partnership, the Investing VIE (as discussed below) and certain properties that have non-controlling interests. These entities are VIEs because the non-controlling interests do not have substantive kick-out or participating rights. The Operating Partnership consolidates certain properties that have non-controlling interests. Included in operating real estate, net on the Company’s consolidated balance sheet as of June 30, 2017 is $348.6 million related to such consolidated VIEs. Included in mortgage notes payable, net on the Company’s consolidated balance sheet as of June 30, 2017 is $324.4 million collateralized by the real estate assets of the related consolidated VIEs. Investing VIEs The Company’s investments in securitization financing entities (“Investing VIEs”), include subordinate first-loss tranches of the securitization trust, which represent interests in such VIE. Investing VIEs are structured as pass through entities that receive principal and interest payments from the underlying debt collateral assets and distribute those payments to the securitization trust’s certificate holders, including the most subordinate tranches of the securitization trust. Generally, a securitization trust designates the most junior subordinate tranche outstanding as the controlling class, which entitles the holder of the controlling class to unilaterally appoint and remove the special servicer for the trust, and as such may qualify as the primary beneficiary of the trust. If it is determined that the Company is the primary beneficiary of an Investing VIE as a result of acquiring the subordinate first-loss tranches of the securitization trust, the Company would consolidate the assets, liabilities, income and expenses of the entire Investing VIE. The assets held by an Investing VIE are restricted and can only be used to fulfill its own obligations. The obligations of an Investing VIE have neither any recourse to the general credit of the Company as the consolidator of an Investing VIE, nor to any of the Company’s other consolidated entities. As of June 30, 2017 , the Company held subordinate tranches of the securitization trust in an Investing VIE for which the Company has determined it is the primary beneficiary because it has the power to direct the activities that most significantly impact the economic performance of the securitization trust. The Company’s subordinate tranches of the securitization trust, which represent the retained interest and related interest income, are eliminated in consolidation. In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation, the assets, liabilities (obligations to the certificate holders of the securitization trust, less the Company’s retained interest from the subordinate tranches of the securitization trust), income and expense of the entire Investing VIE are presented in the consolidated financial statement of the Company. As a result, although the Company legally owns the subordinate tranches of the securitization trust only, U.S. GAAP requires the Company to present the assets, liabilities, income and expenses of the entire securitization trust on its consolidated financial statements. Regardless of the presentation, the Company’s consolidated financial statements of operations ultimately reflect the net income attributable to its retained interest in the subordinate tranches of the securitization trust. Refer to Note 6, “Real Estate Securities, Available for Sale” for further discussion. The Company elected the fair value option for the initial recognition of the assets and liabilities of its consolidated Investing VIEs. Interest income and interest expense associated with this VIE will be recorded separately on the consolidated statements of operations. The Company will separately present the assets and liabilities of its consolidated Investing VIEs as “Mortgage loans held in a securitization trust, at fair value” and “Mortgage obligations issued by a securitization trust, at fair value,” respectively, on its consolidated balance sheets. Refer to Note 12, “Fair Value” for further discussion. The Company has adopted guidance issued by the FASB, allowing the Company to measure both the financial assets and liabilities of a qualifying collateralized financing entity (“CFE”), such as its Investing VIEs, using the fair value of either the CFE’s financial assets or financial liabilities, whichever is more observable. As the liabilities of the Company’s Investing VIE are marketable securities with observable trade data, their fair value is more observable and will be referenced to determine the fair value for assets of its Investing VIE. Refer to section “Fair Value Option” below for further discussion. Unconsolidated VIEs As of June 30, 2017 , the Company identified unconsolidated VIEs related to its securities investments, PE investments and CRE debt investments. Assets of each of the VIEs may only be used to settle obligations of the respective VIE. Creditors of each of the VIEs have no recourse to the general credit of the Company. The following table presents the Company’s classification, carrying value and maximum exposure of unconsolidated VIEs as of June 30, 2017 (dollars in thousands): Carrying Value Maximum Exposure to Loss Real estate securities, available for sale $ 116,691 $ 116,691 Investments in unconsolidated ventures 16,031 16,031 Real estate debt investments, net (1) 142,383 142,383 Total assets $ 275,105 $ 275,105 _______________________________________ (1) Includes loan collateral receivable, related party of $ 51.3 million . Based on management’s analysis, the Company determined that it is not the primary beneficiary of the above VIEs. Accordingly, the VIEs are not consolidated in the Company’s financial statements as of June 30, 2017 . The Company did not provide financial support to the unconsolidated VIEs during the six months ended June 30, 2017 . As of June 30, 2017 , there were no explicit arrangements or implicit variable interests that could require the Company to provide financial support to the unconsolidated VIEs. 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 or a simple majority vote. 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 or the cost method, and for either method, the Company may elect the fair value option. The Company will account for an investment in an unconsolidated entity 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 that it does not have significant influence. 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. 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 preferred returns and allocation formulas, 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) of unconsolidated ventures in the consolidated statements of operations. Any change in fair value attributed to market related assumptions is considered unrealized gain (loss). 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 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. 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 to record certain financial assets and liabilities at fair value on an instrument-by-instrument basis at initial recognition. The Company may elect to apply the fair value option for certain investments due to the nature of the instrument. Any change in fair value for assets and liabilities for which the election is made is recognized in earnings. The Company has elected the fair value option for PE Investments. The Company has also elected the fair value option to account for the eligible financial assets and liabilities of its consolidated Investing VIEs in order to mitigate potential accounting mismatches between the carrying value of the instruments and the related assets and liabilities to be consolidated. The Company has adopted guidance issued by the FASB allowing the Company to measure both the financial assets and liabilities of a qualifying CFE it consolidates using the fair value of either the CFE’s financial assets or financial liabilities, whichever is more observable. Cash and Cash Equivalents The Company considers all highly-liquid investments with an original maturity date of three months or less to be cash equivalents. Cash, including amounts restricted, may at times exceed the Federal Deposit Insurance Corporation deposit insurance limit of $250,000 per institution. The Company mitigates credit risk by placing cash and cash equivalents with major financial institutions. To date, the Company has not experienced any losses on cash and cash equivalents. Restricted Cash Restricted cash consists of amounts related to loan origination (escrow deposits) and operating real estate (escrows for taxes, insurance, capital expenditures and payments required under certain lease agreements). 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 and discount. 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 fair value. The Company may syndicate a portion of the CRE debt investments that it originates or sell the CRE debt investments individually. When a transaction meets the criteria for sale accounting, the Company will no longer recognize the CRE debt investment sold as an asset and will recognize gain or loss based on the difference between the sales price and the carrying value of the CRE debt investment sold. Any related unamortized deferred origination fees, original issue discounts, loan origination costs, discounts or premiums at the time of sale are recognized as an adjustment to the gain or loss on sale, which is included in interest income on the consolidated statement of operations. Any fees received at the time of sale or syndication are recognized as part of interest income. 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 accounts for purchases of operating real estate that qualify as business combinations using the acquisition method, where the purchase price is allocated to tangible assets such as land, building, 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. The Company refers to real estate acquired in connection with a foreclosure, deed in lieu of foreclosure or a consensual modification of a loan as real estate owned (“REO”). The Company evaluates whether REO, herein collectively referred to as taking title to collateral, constitutes a business and whether business combination accounting is appropriate. Any excess upon taking title to collateral between the carrying value of a loan over the estimated fair value of the property is charged to provision for loan losses. Operating real estate is depreciated using the straight-line method over the estimated useful lives of the assets, summarized as follows: Category: Term: Building 30 to 40 years Building improvements Lesser of the useful life or remaining life of the building Land improvements 10 to 30 years Tenant improvements Lesser of the useful life or remaining term of the lease Furniture, fixtures and equipment 3 to 10 years 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 has elected 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 mortgage loans and obligations held in a securitization trust, net in the consolidated statements of operations. As of June 30, 2017 , the Company held subordinate tranches of a securitization trust, which represent the Company’s retained interest in the securitization trust, which the Company consolidates under U.S. GAAP. Refer to Note 6, “Real Estate Securities, Available for Sale” for further discussion. Deferred Costs Deferred costs primarily include deferred financing costs and deferred lease costs. Deferred financing costs represent commitment fees, legal and other third-party costs associated with obtaining financing. Costs related to revolving credit facilities are recorded in deferred costs and other assets, net and are amortized to interest expense using the straight-line basis over the term of the facility. Costs related to other borrowings are recorded net against the carrying value of such borrowings and are amortized to interest expense using the effective interest method. Unamortized deferred financing costs are expensed to realized gain (loss) when the associated facility is repaid before maturity. Costs incurred in seeking financing transactions, which do not close, are expensed in the period in which it is determined that the financing will not occur. Deferred lease costs consist of fees incurred to initiate and renew operating leases, which are amortized on a straight-line basis over the remaining lease term and are recorded to depreciation and amortization in the consolidated statements of operations. Identified Intangibles The Company records acquired identified intangibles, which includes intangible assets (such as the value of the above-market leases, in-place leases, and other intangibles) and intangible liabilities (such as the value of below market leases), based on estimated fair value. The value allocated to the identified intangibles are amortized over the remaining lease term. Above/below-market leases are amortized into rental income, below-market ground leases are amortized into real estate properties-operating expense and in-place leases are amortized into depreciation and amortization expense. Identified intangible assets are recorded in deferred costs and other assets, net, and identified intangible liabilities are recorded in other liabilities on the accompanying consolidated balance sheets. Deferred Costs and Other Assets, Net and Other Liabilities The following tables present a summary of deferred costs and other assets, net and other liabilities as of June 30, 2017 and December 31, 2016 (dollars in thousands): June 30, 2017 (Unaudited) December 31, 2016 Deferred costs and other assets, net: Intangible assets, net (1) $ 34,272 $ 41,375 Deferred commissions and leasing costs 9,905 10,287 Deferred financing costs, net - credit facilities 2,067 2,772 Prepaid expenses 9,179 1,386 Deposits 538 550 Other 343 — Total $ 56,304 $ 56,370 June 30, 2017 (Unaudited) December 31, 2016 Other liabilities: Intangible liabilities, net (2) $ 7,481 $ 8,506 PE Investments deferred purchase price, net 4,050 4,248 Prepaid rent and unearned revenue 3,753 4,601 Tenant security deposits 1,494 1,433 Other 165 403 Total $ 16,943 $ 19,191 _______________________________________ (1) Represents in-place leases and above-market leases, net. (2) Represents below-market leases, net. 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 Company’s directors, including a majority of its independent directors. For the six months ended June 30, 2017 , total acquisition fees and expenses did not exceed the allowed limit for any investment. 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 the leasing of space to various types of tenants. Rental revenue recognition commences when the tenant takes legal possession of the leased space and the leased space is substantially ready for its intended use. 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. The Company amortizes any tenant inducements as a reduction of revenue utilizing the straight-line method over the term of the lease. Other income represents revenue from tenant/operator leases which provide for the recovery of all or a portion of the operating expenses and real estate taxes paid by the Company on behalf of the respective property. This revenue is recognized in the same period as the expenses are incurred. In a situation in which a lease(s) associated with a significant tenant have been, or are expected to be, terminated early, the Company evaluates the remaining useful life of depreciable or amortizable assets in the asset group related to the lease that will be terminated (i.e., tenant improvements, above- and below-market lease intangibles, in-place lease value and deferred leasing costs). Based upon consideration of the facts and circumstances surrounding the termination, the Company may write-off or accelerate the depreciation and amortization associated with the asset group. Such amounts are included within rental and other income for above- and below-market lease intangibles and depreciation and amortization for the remaining lease related asset groups in the consolidated statements of operations. 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 all 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. Interest accrued and not collected will be reversed against interest income. A loan is written off when it is no longer realizable and/or legally discharged. As of June 30, 2017 , the Company did not have any impaired CRE debt investments. 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. As of June 30, 2017 , the Company did not have any impaired operating real estate. 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. 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 as losses occur. CRE securities for which the fair value option is not |
