Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business Operations	Organization and Business Operations Benefit Street Partners Realty Trust, Inc. (the "Company") is a real estate finance company that primarily originates, acquires and manages a diversified portfolio of commercial real estate debt investments secured by properties located within and outside the United States. The Company was incorporated in Maryland on November 15, 2012 and commenced operations on May 14, 2013. The Company made a tax election to be treated as a real estate investment trust (a "REIT") for U.S. federal income tax purposes commencing with its taxable year ended December 31, 2013. The Company believes that it has qualified as a REIT and intends to continue to meet the requirements for qualification and taxation as a REIT. In addition, the Company, through a subsidiary which is treated as a taxable REIT subsidiary (a "TRS") is indirectly subject to U.S federal, state and local income taxes. The majority of the Company's business is conducted through Benefit Street Partners Realty Operating Partnership, L.P. (the “OP”), a Delaware limited partnership. The Company is the sole general partner and directly or indirectly holds all of the units of limited partner interests in the OP. The Company has no direct employees. Benefit Street Partners L.L.C. serves as the Company's advisor (the "Advisor") pursuant to an Amended and Restated Advisory Agreement, dated January 19, 2018 (the "Advisory Agreement"). The Advisor is a wholly owned subsidiary of Franklin Resources, Inc. which, together with its various subsidiaries, operates as Franklin Templeton. Prior to February 1, 2019, the Advisor was in partnership with Providence Equity Partners L.L.C., a global private equity firm. The Advisor, an investment adviser registered with the U.S. Securities and Exchange Commission (“SEC”), is a credit-focused alternative asset management firm. Established in 2008, the Advisor's credit platform manages funds for institutions and high-net-worth investors across various credit funds and complementary strategies including high yield, levered loans, private / opportunistic debt, liquid credit, structured credit and commercial real estate debt. These strategies complement each other as they all leverage the sourcing, analytical, compliance, and operational capabilities that encompass the platform. The Advisor manages the Company's affairs on a day-to-day basis. The Advisor receives compensation and fees for services related to the investment and management of the Company's assets and the operations of the Company. The Company invests in commercial real estate debt investments, which may include first mortgage loans, subordinated mortgage loans, mezzanine loans and participations in such loans. The Company also originates conduit loans which the Company intends to sell through its TRS into commercial mortgage-backed securities ("CMBS") at a profit. The Company also invests in commercial real estate securities. Real estate securities may include CMBS, senior unsecured debt of publicly traded REITs, debt or equity securities of other publicly traded real estate companies and collateralized debt obligations ("CDOs").

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Accounting The accompanying consolidated financial statements and related footnotes have been prepared on the accrual basis of accounting in conformity with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the requirements for reporting on Form 10-K and Regulation S-X, as appropriate. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities as of the date of the financial statements and the reported amounts of income and expenses during the reported periods. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ materially. In the opinion of management, the annual data includes all adjustments, of a normal and recurring nature, necessary for a fair statement of the results for the periods presented. Certain prior period amounts have been reclassified to conform with current presentation. In the opinion of management, all normal recurring adjustments considered necessary for a fair statement of the results of the periods presented have been included. The current period’s results of operations will not necessarily be indicative of results in any subsequent reporting period. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company, the OP and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In determining whether the Company has a controlling financial interest in a joint venture and the requirement to consolidate the accounts of that entity, management considers factors such as ownership interest, authority to make decisions and contractual and substantive participating rights of the other partners or members, as well as whether the entity is a variable interest entity ("VIE") for which the Company is the primary beneficiary. The Company has determined the OP is a VIE of which the Company is the primary beneficiary. Substantially all of the Company's assets and liabilities are held by the OP. The Company consolidates all entities that it controls through either majority ownership or voting rights. In addition, the Company consolidates all VIEs of which the Company is considered the primary beneficiary. VIEs are entities in which equity investors (i) do not have the characteristics of a controlling financial interest and/or (ii) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The entity that consolidates a VIE is its primary beneficiary and is generally the entity with (i) the power to direct the activities that most significantly affect the VIE’s economic performance and (ii) the right to receive benefits from the VIE or the obligation to absorb losses of the VIE that could be significant to the VIE. The accompanying consolidated financial statements include the accounts of collateralized loan obligations ("CLOs") issued and securitized by wholly owned subsidiaries of the Company. The Company has determined the CLOs are VIEs of which the Company's subsidiary is the primary beneficiary. The assets and liabilities of the CLOs are consolidated in the accompanying consolidated balance sheet in accordance with ASC 810, Consolidation . Acquisition Fees and Acquisition Expenses The Company has historically incurred acquisition fees and acquisition expenses payable to the Advisor. The Company’s obligation to pay the Advisor acquisition fees terminated in September 2017. Prior to then, the Company paid the Advisor an acquisition fee based on the principal amount funded by the Company to originate or acquire commercial mortgage loan investments or on the anticipated net equity funded by the Company to acquire real estate securities. Acquisition fees and acquisition expenses paid to the Company's Advisor in connection with the origination and acquisition of commercial mortgage loan investments and acquisition of real estate securities were evaluated based on the nature of the expense to determine if they should be expensed in the period incurred or capitalized and amortized over the life of the investment. The Company capitalizes certain direct costs relating to the loan origination activities and the cost is amortized over the life of the loan. Pursuant to the Advisory Agreement, the Advisor is entitled to an acquisition fee of 1.0% of the principal amount funded by the Company to originate or acquire commercial mortgage loans (or anticipated net equity funded by the Company in the case of acquisition of real estate securities) until the aggregate purchase price for all investments acquired reaches $600,000,000 and reimbursement for insourced acquisition expenses of 0.5% . In September 2017, the Company's aggregate purchase price for all investments acquired reached $600,000,000 , which concurrently terminated the 1.0% acquisition fee payments to the Advisor for all investments subsequent to the limit being reached. Cash and Cash Equivalents Cash consists of amounts deposited with high quality financial institutions. These deposits are guaranteed by the Federal Deposit Insurance Company up to an insurance limit. Cash equivalents include short-term, liquid investments in money market funds with original maturities of 90 days or less when purchased. Cash equivalents includes a $10.3 million certificate of deposit. Restricted Cash Restricted cash primarily consists of cash pledged as margin on repurchase agreements and derivative transactions. The duration of this restricted cash generally matches the duration of the related repurchase agreements or derivative transaction. Commercial Mortgage Loans Held-for-Investment - Commercial mortgage loans that are held for investment purposes and are anticipated to be held until maturity, are carried at cost, net of unamortized acquisition expenses, discounts or premiums and unfunded commitments. Commercial mortgage loans, held for investment purposes, that are deemed to be impaired are carried at amortized cost less a specific allowance for loan losses. Interest income is recorded on the accrual basis and related discounts, premiums and acquisition expenses on investments are amortized over the life of the investment using the effective interest method. Amortization is reflected as an adjustment to interest income in the Company’s consolidated statements of operations. Guaranteed loan exit fees payable by the borrower upon maturity are accreted over the life of the investment using the effective interest method. The accretion of guaranteed loan exit fees is recognized in interest income in the Company's consolidated statements of operations. Held-for-Sale - Commercial mortgage loans that are intended to be sold in the foreseeable future are reported as held-for sale and are transferred at fair value and recorded at the lower of cost or fair value with changes recorded through the statements of operations. Unamortized loan origination costs for commercial mortgage loans held-for-sale that are carried at the lower of cost or fair value are capitalized as part of the carrying value of the loans and recognized upon the sale of such loans. Amortization of origination costs ceases upon transfer of commercial mortgage loans to held-for-sale. For the year ended December 31, 2019 , the Company originated $5.0 million of commercial mortgage loans held-for-sale and sold these loans during the period for net proceeds of approximately $5.0 million . Held-for-Sale, Accounted for Under the Fair Value Option - The fair value option provides an option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, and written loan commitments. The Company has elected to measure commercial mortgage loans held-for-sale in the Company's TRS under the fair value option. These commercial mortgage loans are included in the Commercial mortgage loans, held-for-sale, measured at fair value in the consolidated balance sheet. Interest income received on commercial mortgage loans held-for-sale is recorded on the accrual basis of accounting and is included in interest income in the consolidated statements of operations. Real estate owned Real estate owned (“REO”) represents real estate acquired by the Company through foreclosure, deed in lieu of foreclosure, or purchase. For real estate acquired by the Company through foreclosure, REO assets are recorded at fair value at acquisition and are presented net of accumulated depreciation. For REO assets acquired through purchase, REO assets are recorded at cost at acquisition and are presented net of accumulated depreciation. Real estate assets are depreciated using the straight-line method over estimated useful lives of up to 40 years for buildings and improvements and up to 15 years for furniture, fixtures and equipment. Renovations and/or replacements that improve or extend the life of the real estate asset are capitalized and depreciated over their estimated useful lives. Leases Operating right of use assets "ROU" represent the Company’s right to use an underlying asset during the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based on the present value of fixed lease payments over the lease term. Leases will be classified as either a finance or operating lease, with such classification affecting the pattern and classification of expense recognition in the consolidated statements of operations. For leases greater than 12 months, the Company determines, at the inception of the contract, if the arrangement meets the classification criteria for an operating or finance lease. For leases that have extension options, which can be exercised at the Company's discretion, management uses judgment to determine if it is reasonably certain that such extension options will be elected. If the extension options are reasonably certain to occur, the Company includes the extended term's lease payments in the calculation of the respective lease liability. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The incremental borrowing rate used to discount the lease liability is determined at commencement of the lease, or upon modification of the lease, as the interest rate a lessee would have to pay to borrow on a fully collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. The Company's incremental borrowing rate considers information at both the corporate and property level and analysis of current market conditions for obtaining new financings. All leases as of December 31, 2019 were operating leases. Separately, on October 15, 2019, the Company acquired certain real estate assets which had an existing in-place lease asset. This in-place lease asset is recorded as an Intangible lease asset on the consolidated balance sheet and amortized using the straight-line method over the contractual life of the lease. Allowance for Loan Losses The allowance for loan losses reflects management's estimate of loan losses inherent in the loan portfolio as of the balance sheet date. The reserve is increased or decreased through the loan loss provision or (recovery) on the Company's consolidated statements of operations and is decreased by charge-offs when losses are confirmed through the receipt of assets, such as cash in a pre-foreclosure sale or upon ownership control of the underlying collateral in full satisfaction of the loan upon foreclosure or when significant collection efforts have ceased. The Company uses a uniform process for determining its allowance for loan losses. The allowance for loan losses includes a general, formula-based component and an asset-specific component. General reserves are recorded when (i) available information as of each balance sheet date indicates that it is probable a loss has occurred in the portfolio and (ii) the amount of the loss can be reasonably estimated. The Company estimates loss rates based on historical realized losses experienced in the industry, given the fact the Company has not experienced significant losses, and takes into account current collateral and economic conditions affecting the probability and severity of losses when establishing the allowance for loan losses. The Company performs a comprehensive analysis of its loan portfolio and assigns risk ratings to loans that incorporate management's current judgments about their credit quality based on all known and relevant internal and external factors that may affect collectability. The Company considers, among other things, payment status, lien position, borrower financial resources and investment in collateral, collateral type, project economics and geographic location as well as national and regional economic factors. This methodology results in loans being segmented by risk classification into risk rating categories that are associated with estimated probabilities of default and principal loss. Ratings range from "1" to "5" with "1" representing the lowest risk of loss and "5" representing the highest risk of loss. The asset-specific reserve component relates to reserves for losses on individual impaired loans. 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. This assessment is made on an individual loan basis each quarter based on such factors as payment status, lien position, borrower financial resources and investment in collateral, collateral type, project economics and geographical location as well as national and regional economic factors. A reserve is established for an impaired loan when the present value of payments expected to be received, observable market prices or the estimated fair value of the collateral (for loans that are dependent on the collateral for repayment) is lower than the carrying value of that loan. For collateral dependent impaired loans, impairment is measured using the estimated fair value of collateral less the estimated cost to sell. Valuations are performed or obtained at the time a loan is determined to be impaired and designated non-performing, and they are updated if circumstances indicate that a significant change in value has occurred. The Advisor generally will use either the income approach through internally developed valuation models to estimate the fair value of the collateral for such loans or obtain external "as is" appraisals for loan collateral. A loan is also considered impaired if its terms are modified in a troubled debt restructuring ("TDR"). A TDR occurs when a concession is granted and the debtor is experiencing financial difficulties. Impairments on TDR loans are generally measured based on the present value of expected future cash flows discounted at the effective interest rate of the original loans. The Company generally designates non-performing loans at such time as (i) loan payments become 90-days past due; (ii) the loan has a maturity default; or (iii) in the opinion of the Company, it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan. Income recognition will generally be suspended when a loan is designated non-performing unless the loan is well secured, and resumed only when the suspended loan becomes contractually current and performance is demonstrated to have resumed. A loan will be written off when it is no longer realizable and legally discharged. Real Estate Securities On the acquisition date, all of the Company’s commercial real estate securities were classified as available for sale and carried at fair value, and subsequently any unrealized gains or losses are recognized as a component of accumulated other comprehensive income or loss. The Company may elect the fair value option for its real estate securities, and as a result, any unrealized gains or losses on such real estate securities will be recorded in the Company’s consolidated statement of operations. No such election has been made to date. Related discounts, premiums and acquisition expenses on investments are amortized over the life of the investment using the effective interest method. Amortization is reflected as an adjustment to interest income in the Company’s consolidated statements of operations. Impairment Analysis of Real Estate Securities Commercial real estate securities for which the fair value option has not been elected are periodically evaluated for other-than-temporary impairment. If the fair value of a security is less than its amortized cost, the security is considered impaired. Impairment of a security is considered other-than-temporary when (i) the Company has the intent to sell the impaired security; (ii) it is more likely than not the Company will be required to sell the security; or (iii) the Company does not expect to recover the entire amortized cost of the security. If the Company determines that an other-than-temporary impairment exists and a sale is likely, the impairment charge is recognized as an impairment of assets on the Company's consolidated statement of operations. If a sale is not expected, the portion of the impairment charge related to credit factors is recorded as an impairment of assets on the Company's consolidated statement of operations with the remainder recorded as an unrealized gain or loss on investments reported as a component of accumulated other comprehensive income or loss. Repurchase Agreements Commercial mortgage loans and real estate securities sold under repurchase agreements have been treated as collateralized financing transactions because the Company maintains effective control over the transferred securities. Commercial mortgage loans and real estate securities financed through a repurchase agreement remain on the Company’s consolidated balance sheets as an asset and cash received from the purchaser is recorded as a liability. Interest paid in accordance with repurchase agreements is recorded in interest expense on the Company's consolidated statements of operations. Deferred Financing Costs The deferred financing costs related to the Company's various Master Repurchase Agreements as well as certain prepaid subscription costs are included in Prepaid expenses and other assets on the consolidated balance sheets. Deferred financing cost on the Company's collateralized debt obligations ("CLO") are netted against the Company's CLO payable in the Collateralized debt obligations on the consolidated balance sheets. Deferred financing costs are amortized over the terms of the respective financing agreement using the effective interest method and included in interest expense on the Company's consolidated statements of operations. Unamortized deferred financing costs are generally expensed when the associated debt is refinanced or repaid before maturity. Share Repurchase Program The Company has a Share Repurchase Program (the "SRP"), which became effective as of February 28, 2016, that enables stockholders to sell their shares to the Company. Subject to certain conditions, stockholders that purchased shares of our common stock or received their shares from us (directly or indirectly) through one or more non-cash transactions and have held their shares for a period of at least one year may request that we repurchase their shares of common stock so long as the repurchase otherwise complies with the provisions of Maryland law. Repurchase requests made following the death or qualifying disability of a stockholder will not be subject to any minimum holding period. On August 10, 2017, our board of directors amended the SRP to provide that the repurchase price per share for requests will be equal to the lesser of (i) our most recent estimated per-share NAV, as approved by our board of directors from time to time, and (ii) our book value per share, computed in accordance with GAAP, multiplied by a percentage equal to (i) 92.5% , if the person seeking repurchase has held his or her shares for a period greater than one year and less than two years; (ii) 95% , if the person seeking repurchase has held his or her shares for a period greater than two years and less than three years; (iii) 97.5% , if the person seeking repurchase has held his or her shares for a period greater than three years and less than four years; or (iv) 100% , if the person seeking repurchase has held his or her shares for a period greater than four years or in the case of requests for death or disability. Repurchases pursuant to the SRP, when requested, generally will be made semiannually (each six -month period ending June 30 or December 31, a “fiscal semester”). Repurchases for any fiscal semester will be limited to a maximum of 2.5% of the weighted average number of shares of common stock outstanding during the previous fiscal year, with a maximum for any fiscal year of 5.0% of the weighted average number of shares of common stock outstanding during the previous fiscal year. Funding for repurchases pursuant to the SRP for any given fiscal semester will be limited to proceeds received during that same fiscal semester through the issuance of common stock pursuant to any Dividend Reinvestment Plan ("DRIP") in effect from time to time, provided that the board of directors has the power, in its sole discretion, to determine the amount of shares repurchased during any fiscal semester as well as the amount of funds to be used for that purpose. Due to these limitations, we cannot guarantee that we will be able to accommodate all repurchase requests made during any fiscal semester or fiscal year. However, a stockholder may withdraw its request at any time or ask that we honor the request when funds are available. Pending repurchase requests will be honored on a pro rata basis. We will generally pay repurchase proceeds, less any applicable tax or other withholding required by law, by the 31st day following the end of the fiscal semester during which the repurchase request was made. When a stockholder requests a redemption and the redemption is approved by the board of directors, the Company will reclassify such obligation from equity to a liability based on the settlement value of the obligation. Shares repurchased under the SRP will have the status of authorized but unissued shares. Offering and Related Costs The Company is currently offering shares of the Company’s common stock, Series A convertible preferred stock (“Series A Preferred Stock”) and Series C convertible preferred stock (the “Series C Preferred Stock,” and, together with the Series A Preferred stock, the “Preferred Stock”) in private placements exempt from the registration requirements of the Securities Act of 1933, as amended (the “Offering”). In connection with the Offering, the Company incurred various offering costs and will continue to incur these costs until the Offering is complete. These offering costs include but are not limited to legal, accounting, printing, mailing and filing fees, and diligence expenses of broker-dealers. Offering costs for the common stock are recorded in the Company’s stockholders’ equity, while the offering costs for the Preferred Stock are included within Redeemable convertible preferred stock Series A and Redeemable convertible preferred stock series C, respectively, on the Company’s consolidated balance sheets. Distribution Reinvestment Plan Pursuant to the DRIP, stockholders may elect to reinvest distributions by purchasing shares of common stock in lieu of receiving cash. No dealer manager fees or selling commissions are paid with respect to shares purchased pursuant to the DRIP. Participants purchasing shares pursuant to the DRIP have the same rights and are treated in the same manner as if such shares were issued pursuant to the Offering. The board of directors may designate that certain cash or other distributions be excluded from the DRIP. The Company has the right to amend any aspect of the DRIP or terminate the DRIP with ten days ’ notice to participants. Shares issued under the DRIP are recorded to equity in the consolidated balance sheets in the period distributions are declared. Share-Based Compensation The Company has a share-based incentive plan for certain of the Company's directors, officers and employees of the Advisor and its affiliates. Share-based awards are measured at the grant date fair value and is recognized as compensation expense on a on a straight line basis over the related vesting period of the award. See Note 12 - Share-Based Compensation . Income Taxes The Company has conducted its operations to qualify as a REIT for U.S. federal income tax purposes beginning with its taxable year ended December 31, 2013 . As a REIT, if the Company meets certain organizational and operational requirements and distributes at least 90% of its "REIT taxable income" (determined before the deduction of dividends paid and excluding net capital gains) to its stockholders in a year, it will not be subject to U.S. federal income tax to the extent of the income that it distributes. However, even if the Company qualifies for taxation as a REIT, it may be subject to certain state and local taxes on income in addition to U.S. federal income and excise taxes on its undistributed income. The Company, through its TRS, is indirectly subject to U.S. federal, state and local income taxes. The Company’s TRS is not consolidated for U.S. federal income tax purposes, but is instead taxed as a C corporation. For financial reporting purposes, the TRS is consolidated and a provision for current and deferred taxes is established for the portion of earnings recognized by the Company with respect to its interest in its TRS. Total income tax expense for the years ended December 31, 2019 , December 31, 2018 and December 31, 2017 were $4.5 million , $0.1 million and $0.2 million respectively. The Company uses a more-likely-than-not threshold for recognition and derecognition of tax positions taken or to be taken in a tax return. The Company has assessed its tax positions for all open tax years beginning with December 31, 2016 and concluded that there were no uncertainties to be recognized. The Company’s accounting policy with respect to interest and penalties related to tax uncertainties is to classify these amounts as provision for income taxes. The Company utilizes the TRS to reduce the impact of the prohibited transaction tax and to avoid penalty for the holding of assets not qualifying as real estate assets for purposes of the REIT asset tests. Any income associated with a TRS is fully taxable because the TRS is subject to federal and state income taxes as a domestic C corporation based upon its net income. Derivatives and Hedging Activities In the normal course of business, the Company is exposed to the effect of interest rate changes and may undertake a strategy to limit these risks through the use of derivatives. The Company uses derivatives primarily to economically hedge against interest rates, CMBS spreads and macro market risk in order to minimize volatility. The Company may use a variety of derivative instruments that are considered conventional, including but not limited to: Treasury note futures and credit derivatives on various indices including CMBX and CDX. The Company recognizes all derivatives on the consolidated balance sheets at fair value. The Company does not designate derivatives as hedges to qualify for hedge accounting for financial reporting purposes and therefore any net payments under, or fluctuations in the fair value of these derivatives have been recognized currently in unrealized (gain)/loss on derivative instruments in the accompanying consolidated statements of operations. The Company records derivative asset and liability positions on a gross basis with any collateral posted with or received from counterparties recorded separately within Restricted cash on the Company’s consolidated balance sheets. Certain derivatives that the Company has entered into are subject to master netting agreements with its counterparties, allowing for netting of the same transaction, in the same currency, on the same date. Per Share Data The Company’s Preferred Stock is considered a participating security. As such, the Company is required to include the Preferred Stock in the calculation of basic earnings per share and calculate basic earnings per share using the two-class method. The Company’s dilutive earnings per share calculation is computed using the more dilutive result of the treasury stock method, assuming the participating security is a potential common share, or the two-class method, assuming the participating security is not converted. The Company calculates basic earnings per share by dividing net income applicable to common stock for the period by the weighted-average number of shares of common stock outstanding for that period. Diluted earnings per share reflects the potential dilution that could occur from shares outstanding if potential shares of common stock with a dilutive effect have been issued in connection with the restricted stock plan or upon conversion of the outstanding shares of the Company’s Preferred Stock, except when doing so would be anti-dilutive. Reportable Segments The Company has determined that it has four reportable segments based on how the chief operating decision maker reviews and manages the business. The four reporting segments are as follows: • The real estate debt business which is focused on originating, acquiring and asset managing commercial real estate debt investments, including first mortgage loans, subordinate mortgages, mezzanine loans and participations in such loans. • The real estate securities business which is focused on investing in and asset managing commercial real estate securities primarily consisting of CMBS and may include unsecured REIT debt, CDO notes and other securities. • The commercial Conduit business in the Company's TRS, which is focused on originating and subsequently selling fixed-rate commercial real estate loans into the CMBS securitization market. • The real estate owned business represents real estate acquired by the Company through foreclosure, deed in lieu of foreclosure, or purchase. See Note 16 - Segment Reporting for further information regarding the Company's segments. Redeemable Convertible Preferred Stock The Company’s Preferred Stock is classified outside of permanent equity in the consolidated balance sheets. Subject to certain conditions, the Preferred Stock is redeemable at the option of the holder of Preferred Stock, outside of the control of the Company. As set forth in the Articles Supplementary relating to each of the Series A Preferred Stock and the Series C Preferred Stock (the “Articles Supplementary”) to the Company’s Articles of Amendment and Restatement, the Preferred Stock is redeemable for shares of the Company's common stock, $0.01 par value per share (the "Common Stock") at the option of the shareholder upon a change of control (as defined in the Articles Supplementary) or after the sixth anniversary of the date of issuance. A change in control of the Company occurs if any person acquires more than 50% of the total economic interests or voting power of all securities of the Company, other than in a liquidity event. Shares of Preferred Stock rank senior to shares of Common Stock with respect to rights to receive dividends and to participate in distributions or payments upon any voluntary or involuntary liquidation, dissolution or winding up of the Company. Dividends payable on each share of Preferred Stock will be equal to the greater of (i) an amount equal to $16.67 per share and (ii) the monthly dividend that would have been paid had such share of Preferred Stock been converted to a share of Common Stock, subject to proration in the event that such share of Preferred Stock was not outstanding for the full month. Immediately prior to a “Liquidity Event,” each outstanding share of Series A Preferred Stock shall convert into 299.2 shares of Common Stock, subject to anti-dilution adjustments (the “Conversion Rate”). Series C Preferred Stock will convert into shares of Common Stock at the same Conversion Rate on the one-year anniversary of a Liquidity Event, subject to the Company’s right to accelerate the conver

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The Company uses the two-class method in calculating basic and diluted earnings per share. Net income is allocated between our common stock and other participating securities based on their participation rights. Diluted net income per share has been computed using the weighted average number of shares of common stock outstanding and other dilutive securities. The following table presents a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations and the calculation of basic and diluted earnings per share for the years ended December 31, 2019 , 2018 and 2017 , respectively (dollars in thousands, except share amounts): Year Ended December 31, Numerator 2019 2018 2017 Net income $ 83,924 $ 52,825 $ 33,779 Less: Preferred stock dividends 15,337 3,644 — Less: Undistributed earnings allocated to preferred stock 1,673 — — Net income attributable to common shareholders (for basic and diluted earnings per share) 66,914 49,181 33,779 Denominator Weighted-average common shares outstanding for basic earnings per share 41,859,142 34,268,707 31,772,231 Effect of dilutive shares: Unvested restricted shares 12,504 14,229 12,658 Weighted-average common shares outstanding for diluted earnings per share 41,871,646 36,779,735 31,784,889 Basic earnings per share $ 1.60 $ 1.44 $ 1.06 Diluted earnings per share $ 1.60 $ 1.44 $ 1.06

The Company must distribute 100% of its taxable income (including net capital gains) to avoid paying corporate U.S. federal income taxes. The Company's distributions are payable by the fifth day following each month end to stockholders of record at the close of business each day during the prior month. Distribution payments are dependent on the availability of funds. The Company's board of directors may reduce the amount of distributions paid or suspend distribution payments at any time, and therefore, distributions payments are not assured. For the years ended December 31, 2019 and December 31, 2018 , the Company declared daily common stock distributions equivalent to 1.44 per annum per share, respectively. For the years ended December 31, 2019 and December 31, 2018 , the Company declared monthly Preferred Stock dividends per share equivalent to the amount of common stock distributions that would be paid on a conversion of Preferred Stock into common stock. As of December 31, 2019 and December 31, 2018 , the Company had declared but unpaid common stock distributions of $5.4 million and $4.7 million , respectively. Additionally, as of December 31, 2019 and December 31, 2018 , the Company had declared but unpaid distributions of $1.5 million and $1.1 million for Series A Preferred Stock, respectively and $0.1 million and $0.0 million for Series C Preferred Stock, respectively. These amounts are included in Distributions payable on the Company’s consolidated balance sheets. The Company distributed $59.7 million during the year ended December 31, 2019 , comprised of $45.8 million in cash and $13.9 million in shares of common stock issued under the DRIP. The Company distributed $48.5 million during the year ended December 31, 2018 , comprised of $34.5 million in cash and $14.0 million in shares of common stock issued under the DRIP. Share Repurchase Program The Company's board of directors unanimously approved an amended and restated share repurchase program (the “SRP”), which became effective on February 28, 2016. The SRP enables stockholders to sell their shares to the Company. Subject to certain conditions, stockholders that purchased shares of the Company's common stock or received their shares from us (directly or indirectly) through one or more non-cash transactions and have held their shares for a period of at least one year may request that the Company repurchase their shares of common stock so long as the repurchase otherwise complies with the provisions of Maryland law. Repurchase requests made following the death or qualifying disability of a stockholder will not be subject to any minimum holding period. On August 10, 2017, the Company's board of directors amended the SRP to provide that the repurchase price per share for requests will be equal to the lesser of (i) the Company’s most recent estimated per-share net asset value ("NAV"), as approved by the Company’s board of directors from time to time, and (ii) the Company’s book value per share, computed in accordance with GAAP, multiplied by a percentage equal to (i) 92.5% , if the person seeking repurchase has held his or her shares for a period greater than one year and less than two years; (ii) 95% , if the person seeking repurchase has held his or her shares for a period greater than two years and less than three years; (iii) 97.5% , if the person seeking repurchase has held his or her shares for a period greater than three years and less than four years; or (iv) 100% , if the person seeking repurchase has held his or her shares for a period greater than four years or in the case of requests for death or disability. The Company’s most recent estimated per-share NAV is $18.57 , as determined by the board of directors, as of September 30, 2019. The Company’s GAAP book value per share as of December 31, 2019 is $18.60 . Repurchase requests related to death or a qualifying disability must satisfy certain conditions, each of which are assessed by and at the sole discretion of the Company, including the following conditions. In the case of death, the shareholder must be a natural person (or a revocable grantor trust) and the Company must receive a written notice from the estate of the shareholder, the recipient of the shares through bequest or inheritance, or the trustee in the case of a revocable grantor trust. In the case of a “qualifying disability”, the shareholder must be a natural person (or a revocable grantor trust) and the Company must receive a written notice from the shareholder, or the trustee in the case of a revocable grantor trust, that the condition was not pre-existing on the date the shares were acquired. In order for a disability to be considered a “qualifying disability”, the shareholder must receive and provide evidence (the shareholder application and the notice of final determination) of disability based upon a physical or mental condition or impairment made by a government agency responsible for reviewing and determining disability retirement benefits (e.g. the Social Security Administration). Repurchases pursuant to the SRP, when requested, generally will be made semiannually (each six-month period ending June 30 or December 31, a “fiscal semester”). Repurchases for any fiscal semester will be limited to a maximum of 2.5% of the weighted average number of shares of common stock outstanding during the previous fiscal year, with a maximum for any fiscal year of 5.0% of the weighted average number of shares of common stock outstanding during the previous fiscal year. Funding for repurchases pursuant to the SRP for any given fiscal semester will be limited to proceeds received during that same fiscal semester through the issuance of common stock pursuant to any DRIP in effect from time to time, provided that the Company's board of directors has the power, in its sole discretion, to determine the amount of shares repurchased during any fiscal semester as well as the amount of funds to be used for that purpose. Any repurchase requests received during such fiscal semester will be paid at the price, computed as described above on the last day of such fiscal semester. Due to these limitations, the Company cannot guarantee that the Company will be able to accommodate all repurchase requests made during any fiscal semester or fiscal year. However, a stockholder may withdraw its request at any time or ask that the Company honors the request when funds are available. Pending repurchase requests will be honored on a pro rata basis. The Company will generally pay repurchase proceeds, less any applicable tax or other withholding required by law, by the 31st day following the end of the fiscal semester during which the repurchase request was made. When a stockholder requests redemption and the redemption is approved, the Company will reclassify such obligation from equity to a liability based on the settlement value of the obligation. Shares repurchased under the SRP will have the status of authorized but unissued shares. The following table reflects the number of shares repurchased under the SRP cumulatively through December 31, 2019 : Number of Requests Number of Shares Repurchased Average Price per Share Cumulative as of December 31, 2018 3,845 2,800,414 $ 20.65 January 1 - January 31, 2019 (1) 845 387,530 18.60 February 1 - February 28, 2019 — — N/A March 1 - March 31, 2019 — — N/A April 1 - April 30, 2019 — — N/A May 1 - May 31, 2019 — — N/A June 1 - June 30, 2019 — — N/A July 1 - July 31, 2019 (2) 1,188 354,323 18.65 August 1 - August 31, 2019 — — N/A September 1 - September 30, 2019 — — N/A October 1 - October 31, 2019 — — N/A November 1 - November 30, 2019 — — N/A December 1 - December 31, 2019 — — N/A Cumulative as of December 31, 2019 5,878 3,542,267 $ 20.23 ________________________ (1) Reflects shares repurchased in January 2019 pursuant to repurchase requests submitted for the fiscal semester ended December 31, 2018. (2) Reflects shares repurchased in July 2019 pursuant to repurchase requests submitted for the fiscal semester ended June 30, 2019. Pursuant to the terms of the SRP, the Board only authorized repurchases up to the amount of proceeds reinvested through our DRIP. As a result, redemption requests for this semester in the amount of 1,934,369 shares were not fulfilled.

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation Restricted Share Plan The Company has an employee and director incentive restricted share plan (the "RSP"), which provides the Company with the ability to grant awards of restricted shares to the Company’s directors, officers and employees (if the Company ever has employees), employees of the Advisor and its affiliates, employees of entities that provide services to the Company, directors of the Advisor or of entities that provide services to the Company, the Advisor and its affiliates. The total number of common shares granted under the RSP shall not exceed 5.0% of the Company’s authorized common shares pursuant to the Offering, and in any event, will not exceed 4.0 million shares (as such number may be adjusted for stock splits, stock distributions, combinations and similar events). Restricted share awards entitle the recipient to receive common shares from the Company under terms that provide for vesting over a specified period of time or upon attainment of pre-established performance objectives. Such awards would typically be forfeited with respect to the unvested shares upon the termination of the recipient’s employment or other relationship with the Company. Restricted shares may not, in general, be sold or otherwise transferred until restrictions are removed and the shares have vested. Holders of restricted shares may receive cash distributions prior to the time that the restrictions on the restricted shares have lapsed. Any distributions payable in common shares shall be subject to the same restrictions as the underlying restricted shares.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments GAAP establishes a hierarchy of valuation techniques based on the observability of inputs used in measuring financial instruments at fair values. GAAP establishes market-based or observable inputs as the preferred source of values, followed by valuation models using management assumptions in the absence of market inputs. The three levels of the hierarchy are described below: • Level I - Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. • Level II - Inputs (other than quoted prices included in Level I) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. • Level III - Unobservable inputs that reflect the entity's own assumptions about the assumptions that market participants would use in the pricing of the asset or liability and are consequently not based on market activity, but rather through particular valuation techniques. The determination of where an asset or liability falls in the above hierarchy requires significant judgment and factors specific to the asset or liability. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company evaluates its hierarchy disclosures each quarter and depending on various factors, it is possible that an asset or liability may be classified differently from quarter to quarter. The Company has implemented valuation control processes to validate the fair value of the Company's financial instruments measured at fair value including those derived from pricing models. These control processes are designed to assure that the values used for financial reporting are based on observable inputs wherever possible. In the event that observable inputs are not available, the control processes are designed to assure that the valuation approach utilized is appropriate and consistently applied and the assumptions are reasonable. Financial Instruments Measured at Fair Value on a Recurring Basis CMBS is recorded in real estate securities, available for sale, measured at fair value on the consolidated balance sheets, are valued utilizing both observable and unobservable market inputs. These factors include projected future cash flows, ratings, subordination levels, vintage, remaining lives, credit issues, and recent trades of similar real estate securities. Depending upon the significance of the fair value inputs used in determining these fair values, these real estate securities are classified in either Level II or Level III of the fair value hierarchy. As of December 31, 2019 , the Company obtained third party pricing for determining the fair value of each CMBS investment, which resulted in a Level II classification. As of December 31, 2018 , the Company classified the real estate securities, available for sale, measured at fair value as Level III. Commercial mortgage loans held-for-sale, measured at fair value in the Company's TRS are initially recorded at transaction proceeds, which are considered to be the best initial estimate of fair value. The Company engaged the services of a third party independent valuation firm to determine fair value of certain investments held by the Company. Fair value is determined using a discounted cash flow model that primarily considers changes in interest rates and credit spreads, weighted average life and current performance of the underlying collateral. The Company classified the commercial mortgage loans held-for-sale, measured at fair value as Level III. The fair value for Treasury note futures is derived using market prices. Treasury note futures trade on the Chicago Mercantile Exchange (“CME”). The instruments are a variety of recently issued 10-year U.S. Treasury notes. The future contracts are liquid and are centrally cleared through the CME. Treasury note futures are generally categorized in Level I of the fair value hierarchy. The fair value for credit default swaps and interest rate swaps contracts are derived using pricing models that are widely accepted by marketplace participants. Credit default swaps and interest rate swaps are traded in the OTC market. The pricing models take into account multiple inputs including specific contract terms, interest rate yield curves, interest rates, credit curves, recovery rates, and/or current credit spreads obtained from swap counterparties and other market participants. Most inputs into the models are not subjective as they are observable in the marketplace or set per the contract. Valuation is primarily determined by the difference between the contract spread and the current market spread. The contract spread (or rate) is generally fixed and the market spread is determined by the credit risk of the underlying debt or reference entity. If the underlying indices are liquid and the OTC market for the current spread is active, credit default swaps and interest rate swaps are categorized in Level II of the fair value hierarchy. If the underlying indices are illiquid and the OTC market for the current spread is not active, credit default swaps are categorized in Level III of the fair value hierarchy. The credit default swaps and interest rate swaps are generally categorized in Level II of the fair value hierarchy. A review of the fair value hierarchy classification is conducted on a quarterly basis. Changes in the type of inputs may result in a reclassification for certain assets. The Company's policy with respect to transfers between levels of the fair value hierarchy is to recognize transfers into and out of each level as of the beginning of the reporting period. There were six transfers out of Level III of the fair value hierarchy during the year ended December 31, 2019 . The following table presents the Company's financial instruments carried at fair value on a recurring basis in the consolidated balance sheets by its level in the fair value hierarchy as of December 31, 2019 and December 31, 2018 (dollars in thousands): Total Level I Level II Level III December 31, 2019 Assets, at fair value Real estate securities, available for sale, measured at fair value $ 386,316 $ — $ 386,316 $ — Commercial mortgage loans, held-for-sale, measured at fair value 112,562 — — 112,562 Other real estate investments, measured at fair value 2,557 — — 2,557 Credit default swaps 59 — 59 — Interest rate swaps 325 — 325 — Treasury note futures 735 735 — — Total assets, at fair value $ 502,554 $ 735 $ 386,700 $ 115,119 Liabilities at FV Credit default swaps $ 1,581 $ — $ 1,581 $ — Total liabilities, at fair value 1,581 — 1,581 — December 31, 2018 Assets, at fair value Real estate securities, available for sale, measured at fair value $ 26,412 $ — $ — $ 26,412 Commercial mortgage loans, held-for-sale, measured at fair value 76,863 — 76,863 Credit default swaps 640 — 640 — Interest rate swaps 206 — 206 — Total assets, at fair value $ 104,121 $ — $ 846 $ 103,275 Liabilities, at fair value Interest rate swaps $ 256 $ — $ 256 $ — Treasury note futures 1,063 1,063 — — Total liabilities, at fair value $ 1,319 $ 1,063 $ 256 $ — Both observable and unobservable inputs may be used to determine the fair value of positions that the Company has classified within the Level III category. As a result, the unrealized gains and losses for assets and liabilities within the Level III category may include changes in fair value that were attributable to both observable and unobservable inputs. The following table summarizes the valuation method and significant unobservable inputs used for the Company’s financial instruments that are categorized within Level III of the fair value hierarchy as of December 31, 2019 and December 31, 2018 (dollars in thousands).

The Company has determined that market participants would take these inputs into account when valuing the investments. (2) Inputs were weighted based on the fair value of the investments included in the range. Increases or decreases in any of the above unobservable inputs in isolation would result in a lower or higher fair value measurement for such assets.

The fair value of cash and cash equivalents and restricted cash are measured using observable quoted market prices, or Level I inputs and their carrying value approximates their fair value. The fair value of borrowings under repurchase agreements approximate their carrying value on the consolidated balance sheets due to their short-term nature, and are measured using Level II inputs. Financial Instruments Not Measured at Fair Value The fair values of the Company's commercial mortgage loans, held-for-investment and collateralized loan obligations, which are not reported at fair value on the consolidated balance sheets are reported below as of December 31, 2019 and 2018 (dollars in thousands) Level Carrying Amount Fair Value December 31, 2019 Commercial mortgage loans, held-for-investment (1) Asset III $ 2,762,963 $ 2,784,650 Collateralized loan obligation Liability III 1,803,185 1,822,386 Mortgage note payable Liability III 29,167 29,167 December 31, 2018 Commercial mortgage loans, held-for-investment (1) Asset III $ 2,211,666 $ 2,213,650 Collateralized loan obligation Liability III 1,505,279 1,518,127 Other financing and loan participation - commercial mortgage loans Liability III 9,902 9,902 ________________________ (1) The carrying value is gross of $0.9 million and $4.8 million of allowance for loan losses as of December 31, 2019 and December 31, 2018 , respectively. The fair value of the commercial mortgage loans, held-for-investment is estimated using a discounted cash flow analysis, based on the Advisor's experience with similar types of investments. The Company estimates the fair value of the collateralized loan obligations using external broker quotes. The fair value of the other financing and loan participation-commercial mortgage loans is generally estimated using a discounted cash flow analysis. At December 31, 2019 , the Mortgage note payable was initially recorded at transaction proceeds, which are considered to be the best initial estimate of fair value.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company has conducted its operations to qualify as a REIT for U.S. federal income tax purposes beginning with its taxable year ended December 31, 2013. As a REIT, if the Company meets certain organizational and operational requirements and distributes at least 90% of its "REIT taxable income" (determined before the deduction of dividends paid and excluding net capital gains) to its stockholders in a year, it will not be subject to U.S. federal income tax to the extent of the income that it distributes. However, even if the Company qualifies for taxation as a REIT, it may be subject to certain state and local taxes on income in addition to U.S. federal income and excise taxes on its undistributed income. The Company, through its TRS, is indirectly subject to U.S. federal, state and local income taxes. The Company’s TRS is not consolidated for U.S. federal income tax purposes, but is instead taxed as a C corporation. For financial reporting purposes, the TRS is consolidated and a provision for current and deferred taxes is established for the portion of earnings recognized by the Company with respect to its interest in its TRS. Total income tax expense for the year ended December 31, 2019 , December 31, 2018 and December 31, 2017 were $4.5 million , $0.1 million and $0.2 million , respectively. The Company uses a more-likely-than-not threshold for recognition and derecognition of tax positions taken or to be taken in a tax return. The Company has assessed its tax positions for all open tax years beginning with December 31, 2015 and concluded that there were no uncertainties to be recognized. The Company’s accounting policy with respect to interest and penalties related to tax uncertainties is to classify these amounts as provision for income taxes. Components of the provision for income taxes consist of the following (dollars in thousands): Years Ended December 31, 2019 2018 2017 Current expense (benefit) U.S. Federal $ 4,076 $ 68 $ 140 State and local 397 12 61 Total current expense (benefit) 4,473 80 201 Deferred expense (benefit) U.S. Federal $ 10 $ (1 ) $ 18 State and local — — 6 Total deferred expense (benefit) 10 (1 ) 24 Provision for income tax expense (benefit) $ 4,483 $ 79 $ 225 The tax characteristic of $1.44 distributions per common share declared during 2019 was $1.20 ordinary income and $0.24 return of capital. Of the $1.20 of ordinary income, $1.20 represents the amount of the ordinary dividend that may be eligible for the 20% deduction applicable to qualified REIT dividends under Internal Revenue Code Section 199A. The tax characteristics of $430.88 per share of Series A Preferred stock declared during 2019 was all ordinary income. Of the $430.88 of ordinary income, $430.88 represents the amount of the ordinary dividend that may be eligible for the 20% deduction applicable to qualified REIT dividends under Section 199A. The tax characteristics of $35.41 per share of Series C Preferred stock declared during 2019 was all ordinary income. Of the $35.41 of ordinary income, $35.41 represents the amount of the ordinary dividend that may be eligible for the 20% deduction applicable to qualified REIT dividends under Section 199A. The tax characteristics of the $1.44 distributions per common share declared during 2018 was $1.43 ordinary income and $0.01 return of capital. The tax characteristics of the $216.03 distributions per share of Series A Preferred stock declared during 2018 was all ordinary income. The Company utilizes the TRS to reduce the impact of the prohibited transaction tax and to avoid penalty for the holding of assets not qualifying as real estate assets for purposes of the REIT asset tests. Any income associated with a TRS is fully taxable because the TRS is subject to federal and state income taxes as a domestic C corporation based upon its net income. Enacted on December 22, 2017, the recently passed Tax Cuts and Jobs Act ("TCJA") made many significant changes to the U.S. federal income tax laws applicable to businesses and their owners, including REITs and their stockholders, and may lessen the relative competitive advantage of operating as a REIT rather than as a C corporation. Pursuant to this legislation, as of January 1, 2018, (1) the federal income tax rate applicable to corporations is reduced to 21% , (2) the highest marginal individual income tax rate is reduced to 37% (through taxable years ending in 2025), (3) the corporate alternative minimum tax is repealed, and (4) the backup withholding rate for U.S. stockholders is reduced to 24% . Generally, under the new interest expense limitation rules, the Company’s business interest expense deduction cannot exceed the sum of business interest income, 30% of adjusted taxable income (cannot be less than zero), and any floor plan financing interest expense for the taxable year. The Company completed its assessment of the income tax provisions of the sections of the TCJA that were effective for the year ended December 31, 2019 , and there were no material amounts recorded.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Basis of Accounting	Basis of Accounting The accompanying consolidated financial statements and related footnotes have been prepared on the accrual basis of accounting in conformity with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the requirements for reporting on Form 10-K and Regulation S-X, as appropriate. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities as of the date of the financial statements and the reported amounts of income and expenses during the reported periods. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ materially. In the opinion of management, the annual data includes all adjustments, of a normal and recurring nature, necessary for a fair statement of the results for the periods presented. Certain prior period amounts have been reclassified to conform with current presentation. In the opinion of management, all normal recurring adjustments considered necessary for a fair statement of the results of the periods presented have been included. The current period’s results of operations will not necessarily be indicative of results in any subsequent reporting period.
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company, the OP and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. In determining whether the Company has a controlling financial interest in a joint venture and the requirement to consolidate the accounts of that entity, management considers factors such as ownership interest, authority to make decisions and contractual and substantive participating rights of the other partners or members, as well as whether the entity is a variable interest entity ("VIE") for which the Company is the primary beneficiary. The Company has determined the OP is a VIE of which the Company is the primary beneficiary. Substantially all of the Company's assets and liabilities are held by the OP. The Company consolidates all entities that it controls through either majority ownership or voting rights. In addition, the Company consolidates all VIEs of which the Company is considered the primary beneficiary. VIEs are entities in which equity investors (i) do not have the characteristics of a controlling financial interest and/or (ii) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The entity that consolidates a VIE is its primary beneficiary and is generally the entity with (i) the power to direct the activities that most significantly affect the VIE’s economic performance and (ii) the right to receive benefits from the VIE or the obligation to absorb losses of the VIE that could be significant to the VIE. The accompanying consolidated financial statements include the accounts of collateralized loan obligations ("CLOs") issued and securitized by wholly owned subsidiaries of the Company. The Company has determined the CLOs are VIEs of which the Company's subsidiary is the primary beneficiary. The assets and liabilities of the CLOs are consolidated in the accompanying consolidated balance sheet in accordance with ASC 810, Consolidation .
Acquisition Fees and Acquisition Expenses	Acquisition Fees and Acquisition Expenses The Company has historically incurred acquisition fees and acquisition expenses payable to the Advisor. The Company’s obligation to pay the Advisor acquisition fees terminated in September 2017. Prior to then, the Company paid the Advisor an acquisition fee based on the principal amount funded by the Company to originate or acquire commercial mortgage loan investments or on the anticipated net equity funded by the Company to acquire real estate securities. Acquisition fees and acquisition expenses paid to the Company's Advisor in connection with the origination and acquisition of commercial mortgage loan investments and acquisition of real estate securities were evaluated based on the nature of the expense to determine if they should be expensed in the period incurred or capitalized and amortized over the life of the investment. The Company capitalizes certain direct costs relating to the loan origination activities and the cost is amortized over the life of the loan.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash consists of amounts deposited with high quality financial institutions. These deposits are guaranteed by the Federal Deposit Insurance Company up to an insurance limit. Cash equivalents include short-term, liquid investments in money market funds with original maturities of 90 days or less when purchased.
Restricted Cash	Restricted Cash Restricted cash primarily consists of cash pledged as margin on repurchase agreements and derivative transactions. The duration of this restricted cash generally matches the duration of the related repurchase agreements or derivative transaction.
Commercial Mortgage Loans	Commercial Mortgage Loans Held-for-Investment - Commercial mortgage loans that are held for investment purposes and are anticipated to be held until maturity, are carried at cost, net of unamortized acquisition expenses, discounts or premiums and unfunded commitments. Commercial mortgage loans, held for investment purposes, that are deemed to be impaired are carried at amortized cost less a specific allowance for loan losses. Interest income is recorded on the accrual basis and related discounts, premiums and acquisition expenses on investments are amortized over the life of the investment using the effective interest method. Amortization is reflected as an adjustment to interest income in the Company’s consolidated statements of operations. Guaranteed loan exit fees payable by the borrower upon maturity are accreted over the life of the investment using the effective interest method. The accretion of guaranteed loan exit fees is recognized in interest income in the Company's consolidated statements of operations. Held-for-Sale - Commercial mortgage loans that are intended to be sold in the foreseeable future are reported as held-for sale and are transferred at fair value and recorded at the lower of cost or fair value with changes recorded through the statements of operations. Unamortized loan origination costs for commercial mortgage loans held-for-sale that are carried at the lower of cost or fair value are capitalized as part of the carrying value of the loans and recognized upon the sale of such loans. Amortization of origination costs ceases upon transfer of commercial mortgage loans to held-for-sale. For the year ended December 31, 2019 , the Company originated $5.0 million of commercial mortgage loans held-for-sale and sold these loans during the period for net proceeds of approximately $5.0 million . Held-for-Sale, Accounted for Under the Fair Value Option - The fair value option provides an option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, and written loan commitments. The Company has elected to measure commercial mortgage loans held-for-sale in the Company's TRS under the fair value option. These commercial mortgage loans are included in the Commercial mortgage loans, held-for-sale, measured at fair value in the consolidated balance sheet. Interest income received on commercial mortgage loans held-for-sale is recorded on the accrual basis of accounting and is included in interest income in the consolidated statements of operations. Real estate owned Real estate owned (“REO”) represents real estate acquired by the Company through foreclosure, deed in lieu of foreclosure, or purchase. For real estate acquired by the Company through foreclosure, REO assets are recorded at fair value at acquisition and are presented net of accumulated depreciation. For REO assets acquired through purchase, REO assets are recorded at cost at acquisition and are presented net of accumulated depreciation. Real estate assets are depreciated using the straight-line method over estimated useful lives of up to 40 years for buildings and improvements and up to 15 years for furniture, fixtures and equipment. Renovations and/or replacements that improve or extend the life of the real estate asset are capitalized and depreciated over their estimated useful lives. Leases Operating right of use assets "ROU" represent the Company’s right to use an underlying asset during the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at commencement date based on the present value of fixed lease payments over the lease term. Leases will be classified as either a finance or operating lease, with such classification affecting the pattern and classification of expense recognition in the consolidated statements of operations. For leases greater than 12 months, the Company determines, at the inception of the contract, if the arrangement meets the classification criteria for an operating or finance lease. For leases that have extension options, which can be exercised at the Company's discretion, management uses judgment to determine if it is reasonably certain that such extension options will be elected. If the extension options are reasonably certain to occur, the Company includes the extended term's lease payments in the calculation of the respective lease liability. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The incremental borrowing rate used to discount the lease liability is determined at commencement of the lease, or upon modification of the lease, as the interest rate a lessee would have to pay to borrow on a fully collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. The Company's incremental borrowing rate considers information at both the corporate and property level and analysis of current market conditions for obtaining new financings. All leases as of December 31, 2019 were operating leases. Separately, on October 15, 2019, the Company acquired certain real estate assets which had an existing in-place lease asset. This in-place lease asset is recorded as an Intangible lease asset on the consolidated balance sheet and amortized using the straight-line method over the contractual life of the lease. Allowance for Loan Losses The allowance for loan losses reflects management's estimate of loan losses inherent in the loan portfolio as of the balance sheet date. The reserve is increased or decreased through the loan loss provision or (recovery) on the Company's consolidated statements of operations and is decreased by charge-offs when losses are confirmed through the receipt of assets, such as cash in a pre-foreclosure sale or upon ownership control of the underlying collateral in full satisfaction of the loan upon foreclosure or when significant collection efforts have ceased. The Company uses a uniform process for determining its allowance for loan losses. The allowance for loan losses includes a general, formula-based component and an asset-specific component. General reserves are recorded when (i) available information as of each balance sheet date indicates that it is probable a loss has occurred in the portfolio and (ii) the amount of the loss can be reasonably estimated. The Company estimates loss rates based on historical realized losses experienced in the industry, given the fact the Company has not experienced significant losses, and takes into account current collateral and economic conditions affecting the probability and severity of losses when establishing the allowance for loan losses. The Company performs a comprehensive analysis of its loan portfolio and assigns risk ratings to loans that incorporate management's current judgments about their credit quality based on all known and relevant internal and external factors that may affect collectability. The Company considers, among other things, payment status, lien position, borrower financial resources and investment in collateral, collateral type, project economics and geographic location as well as national and regional economic factors. This methodology results in loans being segmented by risk classification into risk rating categories that are associated with estimated probabilities of default and principal loss. Ratings range from "1" to "5" with "1" representing the lowest risk of loss and "5" representing the highest risk of loss. The asset-specific reserve component relates to reserves for losses on individual impaired loans. 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. This assessment is made on an individual loan basis each quarter based on such factors as payment status, lien position, borrower financial resources and investment in collateral, collateral type, project economics and geographical location as well as national and regional economic factors. A reserve is established for an impaired loan when the present value of payments expected to be received, observable market prices or the estimated fair value of the collateral (for loans that are dependent on the collateral for repayment) is lower than the carrying value of that loan. For collateral dependent impaired loans, impairment is measured using the estimated fair value of collateral less the estimated cost to sell. Valuations are performed or obtained at the time a loan is determined to be impaired and designated non-performing, and they are updated if circumstances indicate that a significant change in value has occurred. The Advisor generally will use either the income approach through internally developed valuation models to estimate the fair value of the collateral for such loans or obtain external "as is" appraisals for loan collateral. A loan is also considered impaired if its terms are modified in a troubled debt restructuring ("TDR"). A TDR occurs when a concession is granted and the debtor is experiencing financial difficulties. Impairments on TDR loans are generally measured based on the present value of expected future cash flows discounted at the effective interest rate of the original loans. The Company generally designates non-performing loans at such time as (i) loan payments become 90-days past due; (ii) the loan has a maturity default; or (iii) in the opinion of the Company, it is probable the Company will be unable to collect all amounts due according to the contractual terms of the loan. Income recognition will generally be suspended when a loan is designated non-performing unless the loan is well secured, and resumed only when the suspended loan becomes contractually current and performance is demonstrated to have resumed. A loan will be written off when it is no longer realizable and legally discharged.
Real Estate Securities	Real Estate Securities On the acquisition date, all of the Company’s commercial real estate securities were classified as available for sale and carried at fair value, and subsequently any unrealized gains or losses are recognized as a component of accumulated other comprehensive income or loss. The Company may elect the fair value option for its real estate securities, and as a result, any unrealized gains or losses on such real estate securities will be recorded in the Company’s consolidated statement of operations. No such election has been made to date. Related discounts, premiums and acquisition expenses on investments are amortized over the life of the investment using the effective interest method. Amortization is reflected as an adjustment to interest income in the Company’s consolidated statements of operations. Impairment Analysis of Real Estate Securities Commercial real estate securities for which the fair value option has not been elected are periodically evaluated for other-than-temporary impairment. If the fair value of a security is less than its amortized cost, the security is considered impaired. Impairment of a security is considered other-than-temporary when (i) the Company has the intent to sell the impaired security; (ii) it is more likely than not the Company will be required to sell the security; or (iii) the Company does not expect to recover the entire amortized cost of the security. If the Company determines that an other-than-temporary impairment exists and a sale is likely, the impairment charge is recognized as an impairment of assets on the Company's consolidated statement of operations. If a sale is not expected, the portion of the impairment charge related to credit factors is recorded as an impairment of assets on the Company's consolidated statement of operations with the remainder recorded as an unrealized gain or loss on investments reported as a component of accumulated other comprehensive income or loss.
Repurchase Agreements	Repurchase Agreements Commercial mortgage loans and real estate securities sold under repurchase agreements have been treated as collateralized financing transactions because the Company maintains effective control over the transferred securities. Commercial mortgage loans and real estate securities financed through a repurchase agreement remain on the Company’s consolidated balance sheets as an asset and cash received from the purchaser is recorded as a liability. Interest paid in accordance with repurchase agreements is recorded in interest expense on the Company's consolidated statements of operations. Share Repurchase Program The Company has a Share Repurchase Program (the "SRP"), which became effective as of February 28, 2016, that enables stockholders to sell their shares to the Company. Subject to certain conditions, stockholders that purchased shares of our common stock or received their shares from us (directly or indirectly) through one or more non-cash transactions and have held their shares for a period of at least one year may request that we repurchase their shares of common stock so long as the repurchase otherwise complies with the provisions of Maryland law. Repurchase requests made following the death or qualifying disability of a stockholder will not be subject to any minimum holding period. On August 10, 2017, our board of directors amended the SRP to provide that the repurchase price per share for requests will be equal to the lesser of (i) our most recent estimated per-share NAV, as approved by our board of directors from time to time, and (ii) our book value per share, computed in accordance with GAAP, multiplied by a percentage equal to (i) 92.5% , if the person seeking repurchase has held his or her shares for a period greater than one year and less than two years; (ii) 95% , if the person seeking repurchase has held his or her shares for a period greater than two years and less than three years; (iii) 97.5% , if the person seeking repurchase has held his or her shares for a period greater than three years and less than four years; or (iv) 100% , if the person seeking repurchase has held his or her shares for a period greater than four years or in the case of requests for death or disability. Repurchases pursuant to the SRP, when requested, generally will be made semiannually (each six -month period ending June 30 or December 31, a “fiscal semester”). Repurchases for any fiscal semester will be limited to a maximum of 2.5% of the weighted average number of shares of common stock outstanding during the previous fiscal year, with a maximum for any fiscal year of 5.0% of the weighted average number of shares of common stock outstanding during the previous fiscal year. Funding for repurchases pursuant to the SRP for any given fiscal semester will be limited to proceeds received during that same fiscal semester through the issuance of common stock pursuant to any Dividend Reinvestment Plan ("DRIP") in effect from time to time, provided that the board of directors has the power, in its sole discretion, to determine the amount of shares repurchased during any fiscal semester as well as the amount of funds to be used for that purpose. Due to these limitations, we cannot guarantee that we will be able to accommodate all repurchase requests made during any fiscal semester or fiscal year. However, a stockholder may withdraw its request at any time or ask that we honor the request when funds are available. Pending repurchase requests will be honored on a pro rata basis. We will generally pay repurchase proceeds, less any applicable tax or other withholding required by law, by the 31st day following the end of the fiscal semester during which the repurchase request was made. When a stockholder requests a redemption and the redemption is approved by the board of directors, the Company will reclassify such obligation from equity to a liability based on the settlement value of the obligation. Shares repurchased under the SRP will have the status of authorized but unissued shares.
Deferred Financing Costs	Deferred Financing Costs The deferred financing costs related to the Company's various Master Repurchase Agreements as well as certain prepaid subscription costs are included in Prepaid expenses and other assets on the consolidated balance sheets. Deferred financing cost on the Company's collateralized debt obligations ("CLO") are netted against the Company's CLO payable in the Collateralized debt obligations on the consolidated balance sheets. Deferred financing costs are amortized over the terms of the respective financing agreement using the effective interest method and included in interest expense on the Company's consolidated statements of operations. Unamortized deferred financing costs are generally expensed when the associated debt is refinanced or repaid before maturity.

Shares repurchased under the SRP will have the status of authorized but unissued shares.
Offering and Related Costs	Offering and Related Costs The Company is currently offering shares of the Company’s common stock, Series A convertible preferred stock (“Series A Preferred Stock”) and Series C convertible preferred stock (the “Series C Preferred Stock,” and, together with the Series A Preferred stock, the “Preferred Stock”) in private placements exempt from the registration requirements of the Securities Act of 1933, as amended (the “Offering”). In connection with the Offering, the Company incurred various offering costs and will continue to incur these costs until the Offering is complete. These offering costs include but are not limited to legal, accounting, printing, mailing and filing fees, and diligence expenses of broker-dealers. Offering costs for the common stock are recorded in the Company’s stockholders’ equity, while the offering costs for the Preferred Stock are included within Redeemable convertible preferred stock Series A and Redeemable convertible preferred stock series C, respectively, on the Company’s consolidated balance sheets.
Distribution Reinvestment Plan	Distribution Reinvestment Plan Pursuant to the DRIP, stockholders may elect to reinvest distributions by purchasing shares of common stock in lieu of receiving cash. No dealer manager fees or selling commissions are paid with respect to shares purchased pursuant to the DRIP. Participants purchasing shares pursuant to the DRIP have the same rights and are treated in the same manner as if such shares were issued pursuant to the Offering. The board of directors may designate that certain cash or other distributions be excluded from the DRIP. The Company has the right to amend any aspect of the DRIP or terminate the DRIP with ten days ’ notice to participants. Shares issued under the DRIP are recorded to equity in the consolidated balance sheets in the period distributions are declared.
Share-Based Compensation	Share-Based Compensation The Company has a share-based incentive plan for certain of the Company's directors, officers and employees of the Advisor and its affiliates. Share-based awards are measured at the grant date fair value and is recognized as compensation expense on a on a straight line basis over the related vesting period of the award.
Income Taxes	Income Taxes The Company has conducted its operations to qualify as a REIT for U.S. federal income tax purposes beginning with its taxable year ended December 31, 2013 . As a REIT, if the Company meets certain organizational and operational requirements and distributes at least 90% of its "REIT taxable income" (determined before the deduction of dividends paid and excluding net capital gains) to its stockholders in a year, it will not be subject to U.S. federal income tax to the extent of the income that it distributes. However, even if the Company qualifies for taxation as a REIT, it may be subject to certain state and local taxes on income in addition to U.S. federal income and excise taxes on its undistributed income. The Company, through its TRS, is indirectly subject to U.S. federal, state and local income taxes. The Company’s TRS is not consolidated for U.S. federal income tax purposes, but is instead taxed as a C corporation. For financial reporting purposes, the TRS is consolidated and a provision for current and deferred taxes is established for the portion of earnings recognized by the Company with respect to its interest in its TRS. Total income tax expense for the years ended December 31, 2019 , December 31, 2018 and December 31, 2017 were $4.5 million , $0.1 million and $0.2 million respectively. The Company uses a more-likely-than-not threshold for recognition and derecognition of tax positions taken or to be taken in a tax return. The Company has assessed its tax positions for all open tax years beginning with December 31, 2016 and concluded that there were no uncertainties to be recognized. The Company’s accounting policy with respect to interest and penalties related to tax uncertainties is to classify these amounts as provision for income taxes. The Company utilizes the TRS to reduce the impact of the prohibited transaction tax and to avoid penalty for the holding of assets not qualifying as real estate assets for purposes of the REIT asset tests. Any income associated with a TRS is fully taxable because the TRS is subject to federal and state income taxes as a domestic C corporation based upon its net income.
Derivatives and Hedging Activities	Derivatives and Hedging Activities In the normal course of business, the Company is exposed to the effect of interest rate changes and may undertake a strategy to limit these risks through the use of derivatives. The Company uses derivatives primarily to economically hedge against interest rates, CMBS spreads and macro market risk in order to minimize volatility. The Company may use a variety of derivative instruments that are considered conventional, including but not limited to: Treasury note futures and credit derivatives on various indices including CMBX and CDX. The Company recognizes all derivatives on the consolidated balance sheets at fair value. The Company does not designate derivatives as hedges to qualify for hedge accounting for financial reporting purposes and therefore any net payments under, or fluctuations in the fair value of these derivatives have been recognized currently in unrealized (gain)/loss on derivative instruments in the accompanying consolidated statements of operations. The Company records derivative asset and liability positions on a gross basis with any collateral posted with or received from counterparties recorded separately within Restricted cash on the Company’s consolidated balance sheets. Certain derivatives that the Company has entered into are subject to master netting agreements with its counterparties, allowing for netting of the same transaction, in the same currency, on the same date.
Per Share Data	Per Share Data The Company’s Preferred Stock is considered a participating security. As such, the Company is required to include the Preferred Stock in the calculation of basic earnings per share and calculate basic earnings per share using the two-class method. The Company’s dilutive earnings per share calculation is computed using the more dilutive result of the treasury stock method, assuming the participating security is a potential common share, or the two-class method, assuming the participating security is not converted. The Company calculates basic earnings per share by dividing net income applicable to common stock for the period by the weighted-average number of shares of common stock outstanding for that period. Diluted earnings per share reflects the potential dilution that could occur from shares outstanding if potential shares of common stock with a dilutive effect have been issued in connection with the restricted stock plan or upon conversion of the outstanding shares of the Company’s Preferred Stock, except when doing so would be anti-dilutive.
Reportable Segments	Reportable Segments The Company has determined that it has four reportable segments based on how the chief operating decision maker reviews and manages the business. The four reporting segments are as follows: • The real estate debt business which is focused on originating, acquiring and asset managing commercial real estate debt investments, including first mortgage loans, subordinate mortgages, mezzanine loans and participations in such loans. • The real estate securities business which is focused on investing in and asset managing commercial real estate securities primarily consisting of CMBS and may include unsecured REIT debt, CDO notes and other securities. • The commercial Conduit business in the Company's TRS, which is focused on originating and subsequently selling fixed-rate commercial real estate loans into the CMBS securitization market. • The real estate owned business represents real estate acquired by the Company through foreclosure, deed in lieu of foreclosure, or purchase.
Redeemable Convertible Preferred Stock	Redeemable Convertible Preferred Stock The Company’s Preferred Stock is classified outside of permanent equity in the consolidated balance sheets. Subject to certain conditions, the Preferred Stock is redeemable at the option of the holder of Preferred Stock, outside of the control of the Company. As set forth in the Articles Supplementary relating to each of the Series A Preferred Stock and the Series C Preferred Stock (the “Articles Supplementary”) to the Company’s Articles of Amendment and Restatement, the Preferred Stock is redeemable for shares of the Company's common stock, $0.01 par value per share (the "Common Stock") at the option of the shareholder upon a change of control (as defined in the Articles Supplementary) or after the sixth anniversary of the date of issuance. A change in control of the Company occurs if any person acquires more than 50% of the total economic interests or voting power of all securities of the Company, other than in a liquidity event. Shares of Preferred Stock rank senior to shares of Common Stock with respect to rights to receive dividends and to participate in distributions or payments upon any voluntary or involuntary liquidation, dissolution or winding up of the Company. Dividends payable on each share of Preferred Stock will be equal to the greater of (i) an amount equal to $16.67 per share and (ii) the monthly dividend that would have been paid had such share of Preferred Stock been converted to a share of Common Stock, subject to proration in the event that such share of Preferred Stock was not outstanding for the full month. Immediately prior to a “Liquidity Event,” each outstanding share of Series A Preferred Stock shall convert into 299.2 shares of Common Stock, subject to anti-dilution adjustments (the “Conversion Rate”). Series C Preferred Stock will convert into shares of Common Stock at the same Conversion Rate on the one-year anniversary of a Liquidity Event, subject to the Company’s right to accelerate the conversion to a date no earlier than six months after the Liquidity Event, upon at least ten days prior notice to the holders of the Series C Preferred Stock. A “Liquidity Event” is defined as (i) the listing of the Common Stock on a national securities exchange or quotation on an electronic inter-dealer quotation system; (ii) a merger or business combination involving the Company pursuant to which outstanding shares Common Stock are exchanged for securities of another company which are listed on a national securities exchange or quoted on an electronic inter-dealer quotation system; or (iii) any other transaction or series of transaction that results in all shares of Common Stock being transferred or exchange for cash or securities which are listed on a national securities exchange or quoted on an electronic inter-dealer quotation system. If there has not been a Liquidity Event within six years from the initial issuance of the Preferred Stock, each holder of Preferred Stock shall have the right to convert all, but not less than all, of the Preferred Stock held by such holder into Common Stock at the Conversion Rate. Each holder also has the option to convert its shares of Preferred Stock into Common Stock upon a change in control (as defined in the respective Articles Supplementary for the Series A Preferred Stock and Series C Preferred Stock) of the Company. In addition, neither the Company nor a holder of shares of Preferred Stock may redeem shares of the Preferred Stock until six years from the initial issuance of the Preferred Stock, except in cases of a change in control (as defined in the respective Articles Supplementary). Holders of the Preferred Stock are entitled to vote on each matter submitted to a vote of the stockholders of the Company upon which the holders of Common Stock are entitled to vote, upon which the holders of the Preferred Stock and holders of the Common Stock shall vote together as a single class. The number of votes applicable to a share of Preferred Stock will be equal to the number of shares of Common Stock a share of Preferred Stock could have been converted into as of the record date set for purposes of such stockholder vote (rounded down to the nearest whole number of shares of Common Stock). In addition, the affirmative vote of the holders of two-thirds of the outstanding shares of Preferred Stock is required to approve the issuance of any equity securities senior to the Preferred Stock and to take certain actions materially adverse to the holders of the Preferred Stock.
Recently Adopted Accounting Pronouncements and Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") 2016-02 ("ASC 842"), Leases, which replaced Topic 840, Leases, and requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements ("ASU 2016-02"). ASC 842 was subsequently amended by ASU 2018-01, “Land Easement Practical Expedient for Transition to ASC 842” ("ASU 2018-01"); ASU 2018-10, Codification Improvements to ASC 842, Leases” ("ASU 2018-10"); and ASU 2018-11, “Targeted Improvements” ("ASU 2018-11"). The new standard establishes a right-of-use ("ROU") model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. The Company adopted ASC 842 on January 1, 2019. Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The standard and subsequent amendments, known as the Current Expected Credit Loss (“CECL”) model, significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. CECL amends the existing credit loss model to reflect a reporting entity's current estimate of all expected credit losses, not only based on historical experience and current conditions, but also by including reasonable and supportable forecasts incorporating forward-looking information. For available-for-sale (“AFS”) debt securities, unrealized credit losses will be recognized as allowances rather than reductions in amortized cost basis and elimination of the OTTI concept will result in more frequent estimation of credit losses. ASU No. 2016-13 is effective for fiscal years and interim periods beginning after December 15, 2019, and will be adopted through a cumulative-effect adjustment to accumulated deficit as of January 1, 2020. The CECL reserve required under ASU 2016-13 is a valuation account that is deducted from the amortized cost basis of the related loans and AFS debt securities on our consolidated balance sheets, which will reduce our stockholders’ equity. The initial CECL reserve recorded on January 1, 2020 will be reflected as a direct charge against retained earnings; however, future net changes to the CECL reserve will be recognized in net income on our consolidated statement of operations. ASU 2016-13 does not require use of a particular method for determining the CECL reserve, but it does specify the allowance should be based on relevant information about past events, including historical loss experience, composition of the current loan and AFS debt securities portfolio, current conditions, and reasonable and supportable forecasts for the expected term of each loan. We expect that recognition of credit losses will generally be accelerated under the CECL model. Additionally, but for a few narrow exceptions, ASU 2016-13 does not have a minimum threshold for recognition of impairment losses and requires that all financial instruments, including those for which there is a low risk of loss, incur some amount of valuation reserve to reflect the inherent risk of loss regardless of credit quality, amount of subordinate capital, or other risk mitigants. As part of the implementation process, we have utilized loan loss forecasting models and have implemented policies, systems and controls necessary for the implementation and ongoing measurement of the CECL reserve. We elected to utilize a widely-used analytical model incorporating a loss-given-default methodology and loan performance data for commercial real estate loans dating back to 1998. Our loans may include commitments to fund incremental proceeds to our borrowers over the life of the loan, which are also subject to the CECL model. The CECL reserve related to future loan funding will be recorded as a component of Other Liabilities on our balance sheet and be estimated using the same process as for our outstanding loan balances. Changes in this component of the CECL reserve will similarly impact our consolidated net income. Upon adoption of ASU 2016-13 on January 1, 2020, we expect to record a cumulative-effect adjustment to our accumulated deficit of $7.8 million , or $0.18 book value per share, which is 0.27% of the aggregate commitment amount of the Company’s loan portfolio at December 31, 2019. We do not expect the impact of CECL on our portfolio of AFS debt securities to be material. In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820), Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement" ("ASU 2018-13"). The guidance provides amendments to the fair value measurement disclosure requirements of ASC 820. ASU 2018-13 is effective for all entities for fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for any eliminated or modified disclosures upon issuance of this ASU. The Company is currently evaluating the impact of this new guidance. The Company does not expect the adoption of ASU 2018-13 to have a material impact on its financial statements and related discourses.
Fair Value of Financial Instruments	Fair Value of Financial Instruments GAAP establishes a hierarchy of valuation techniques based on the observability of inputs used in measuring financial instruments at fair values. GAAP establishes market-based or observable inputs as the preferred source of values, followed by valuation models using management assumptions in the absence of market inputs. The three levels of the hierarchy are described below: • Level I - Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. • Level II - Inputs (other than quoted prices included in Level I) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. • Level III - Unobservable inputs that reflect the entity's own assumptions about the assumptions that market participants would use in the pricing of the asset or liability and are consequently not based on market activity, but rather through particular valuation techniques. The determination of where an asset or liability falls in the above hierarchy requires significant judgment and factors specific to the asset or liability. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company evaluates its hierarchy disclosures each quarter and depending on various factors, it is possible that an asset or liability may be classified differently from quarter to quarter. The Company has implemented valuation control processes to validate the fair value of the Company's financial instruments measured at fair value including those derived from pricing models. These control processes are designed to assure that the values used for financial reporting are based on observable inputs wherever possible. In the event that observable inputs are not available, the control processes are designed to assure that the valuation approach utilized is appropriate and consistently applied and the assumptions are reasonable. Financial Instruments Measured at Fair Value on a Recurring Basis CMBS is recorded in real estate securities, available for sale, measured at fair value on the consolidated balance sheets, are valued utilizing both observable and unobservable market inputs. These factors include projected future cash flows, ratings, subordination levels, vintage, remaining lives, credit issues, and recent trades of similar real estate securities. Depending upon the significance of the fair value inputs used in determining these fair values, these real estate securities are classified in either Level II or Level III of the fair value hierarchy. As of December 31, 2019 , the Company obtained third party pricing for determining the fair value of each CMBS investment, which resulted in a Level II classification. As of December 31, 2018 , the Company classified the real estate securities, available for sale, measured at fair value as Level III. Commercial mortgage loans held-for-sale, measured at fair value in the Company's TRS are initially recorded at transaction proceeds, which are considered to be the best initial estimate of fair value. The Company engaged the services of a third party independent valuation firm to determine fair value of certain investments held by the Company. Fair value is determined using a discounted cash flow model that primarily considers changes in interest rates and credit spreads, weighted average life and current performance of the underlying collateral. The Company classified the commercial mortgage loans held-for-sale, measured at fair value as Level III. The fair value for Treasury note futures is derived using market prices. Treasury note futures trade on the Chicago Mercantile Exchange (“CME”). The instruments are a variety of recently issued 10-year U.S. Treasury notes. The future contracts are liquid and are centrally cleared through the CME. Treasury note futures are generally categorized in Level I of the fair value hierarchy. The fair value for credit default swaps and interest rate swaps contracts are derived using pricing models that are widely accepted by marketplace participants. Credit default swaps and interest rate swaps are traded in the OTC market. The pricing models take into account multiple inputs including specific contract terms, interest rate yield curves, interest rates, credit curves, recovery rates, and/or current credit spreads obtained from swap counterparties and other market participants. Most inputs into the models are not subjective as they are observable in the marketplace or set per the contract. Valuation is primarily determined by the difference between the contract spread and the current market spread. The contract spread (or rate) is generally fixed and the market spread is determined by the credit risk of the underlying debt or reference entity. If the underlying indices are liquid and the OTC market for the current spread is active, credit default swaps and interest rate swaps are categorized in Level II of the fair value hierarchy. If the underlying indices are illiquid and the OTC market for the current spread is not active, credit default swaps are categorized in Level III of the fair value hierarchy. The credit default swaps and interest rate swaps are generally categorized in Level II of the fair value hierarchy.
