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. 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.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Accounting The Company's unaudited 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") for interim financial statements and pursuant to the requirements for reporting on Form 10-Q and Regulation S-X, as appropriate. Accordingly, the consolidated financial statements may not include all of the information and notes required by GAAP for annual consolidated financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto as of, and for the year ended December 31, 2019 , which are included in the Company's Annual Report on Form 10-K/A filed with the SEC on March 19, 2020 . Use of Estimates 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 interim data includes all adjustments, of a normal and recurring nature, necessary for a fair statement of the results for the periods presented. The current period’s results of operations will not necessarily be indicative of results that ultimately may be achieved for the entire year or any subsequent interim periods. In response to the global coronavirus (COVID-19) pandemic, numerous countries, including the U.S., have declared national emergencies with respect to COVID-19 and certain jurisdictions, including those where our corporate headquarters and/or properties that secure our investments, or properties that we own, are located, have at times imposed “stay-at-home” guidelines or orders or other restrictions to help prevent its spread. The disruptive economic effects of the COVID-19 pandemic and government responses thereto have significantly impacted our estimates involving credit losses and fair values during the three and six months ended June 30, 2020 , including introducing a significant degree of uncertainty underlying those estimates. 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 sheets in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation. Acquisition Expenses The Company capitalizes certain direct costs relating to loan origination activities and the cost is amortized over the life of the loan. 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 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 credit 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 commitment 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 commitment 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. 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 sheets. Interest income received on commercial mortgage loans held-for-sale, measured at fair value is recorded on the accrual basis of accounting and is included in interest income in the consolidated statements of operations. Acquisition expenses on originating these investments are expensed when incurred. Real estate owned Real estate owned (“REO”) represents real estate acquired by the Company through foreclosure, deed in lieu of foreclosure, or purchase. REO assets are carried at their estimated fair value at acquisition and are presented net of accumulated depreciation and impairment charges. The Company allocates the purchase price of acquired real estate assets based on the fair value of the acquired land, building, furniture, fixtures and equipment. 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. Real estate owned assets that are probable to be sold within one year are reported as held-for sale. Real estate owned assets classified as held-for-sale shall be measured at the lower of its carrying amount or fair value less cost to sell. Real estate owned assets shall not be depreciated or amortized while it is classified as held-for-sale. Interest and other expenses attributable to the liabilities of a disposal group classified as held-for-sale shall continue to be accrued. 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 June 30, 2020 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 sheets and amortized using the straight-line method over the contractual life of the lease. Credit Losses In June 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments-Credit Losses, which amends the credit impairment model for financial instruments. The Company adopted ASU 2016-13 on January 1, 2020. Following our adoption of ASU 2016-13, our previous incurred loss model was replaced with a lifetime current expected credit loss (“CECL”) model for financial instruments carried at amortized cost and off-balance sheet credit exposures, such as loans, loan commitments, held-to-maturity (“HTM”) debt securities, financial guarantees, net investments in leases, reinsurance and trade receivables, which will generally result in earlier recognition of allowance for losses. For available for sale (“AFS”) debt securities, unrealized credit losses are recognized as allowances rather than reductions in amortized cost basis and elimination of the other than temporary impairment concept will result in more frequent estimation of credit losses. The accounting model for purchased credit impaired loans and debt securities has been simplified, including elimination of some of the asymmetrical treatment between credit losses and credit recoveries, to be consistent with the CECL model for originated and purchased non-credit impaired assets. The adopted model for ASC 326 as it applies to HTM and AFS securities, encompassing the beneficial interest model for securities that are not of high credit quality, has been clarified to include the effective interest method as a basis for the projection of cash collections method in connection with the newly adopted impairment models for HTM and AFS debt securities under ASC 326 when securities are not of high credit quality. Upon adoption of ASU 2016-13 on January 1, 2020, we recorded an additional allowance for credit losses for our outstanding loans and unfunded loan commitments of $7.8 million , or $0.18 per share, which was 0.27% of the aggregate commitment amount of the Company’s loan portfolio at December 31, 2019. Pre-adoption Transition Adjustment Post-adjustment Assets Commercial mortgage loans, held for investment, net of allowance 2,762,042 (7,211 ) 2,754,831 Liabilities Accounts payable and accrued expenses (1) 10,925 (550 ) 10,375 Equity Accumulated deficit (85,968 ) (7,761 ) (93,729 ) ________________________ (1) Includes allowance associated with unfunded loan commitment. The following discussion highlights changes to the Company’s accounting policies as a result of this adoption. Allowance for credit losses The allowance for credit losses for the Company’s financial instruments carried at amortized cost and off-balance sheet credit exposures, such as loans held for investment and unfunded loan commitments represents a lifetime estimate of expected credit losses. Factors considered by the Company when determining the allowance for credit losses reserve include loan-specific characteristics such as loan-to-value (“LTV”) ratio, vintage year, loan term, property type, occupancy and geographic location, financial performance of the borrower, expected payments of principal and interest, as well as internal or external information relating to past events, current conditions and reasonable and supportable forecasts. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist for multiple financial instruments. If similar risk characteristics do not exist, the Company measures the allowance for credit losses on an individual instrument basis. The determination of whether a particular financial instrument should be included in a pool can change over time. If a financial asset’s risk characteristics change, the Company evaluates whether it is appropriate to continue to keep the financial instrument in its existing pool or evaluate it individually. In measuring the allowance for credit losses for financial instruments including our unfunded loan commitments that share similar risk characteristics, the Company primarily applies a probability of default (“PD”)/loss given default (“LGD”) model for instruments that are collectively assessed, whereby the allowance for credit losses is calculated as the product of PD, LGD and exposure at default (“EAD”). The Company’s model principally utilizes historical loss rates derived from a commercial mortgage backed securities database with historical losses from 1998 to 2020 provided by a reputable third party, forecasting the loss parameters using a scenario-based statistical approach over a reasonable and supportable forecast period of twelve months, followed by an immediate reversion to average historical losses. For financial instruments assessed on an individual basis, including when it is probable that the Company will be unable to collect the full payment of principal and interest on the instrument, the Company applies a discounted cash flow (“DCF”) methodology. For financial instruments where the borrower is experiencing financial difficulty based on the Company’s assessment at the reporting date and the repayment is expected to be provided substantially through the operation or sale of the collateral, the Company may elect to use as a practical expedient the fair value of the collateral at the reporting date when determining the allowance for credit losses. In developing the allowance for credit losses for its loans held for investment, 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, using similar factors as those in developing the allowance for credit losses. 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. Risk rating categories range from "1" to "5" with "1" representing the lowest risk of loss and "5" representing the highest risk of loss with the ratings updated quarterly. At the time of origination or purchase, loans held for investment are ranked as a “2” and will move accordingly going forward based on the ratings which are defined as follows: 1. Very Low Risk- Investment exceeding fundamental performance expectations and/or capital gain expected. Trends and risk factors since time of investment are favorable. 2. Low Risk- Performing consistent with expectations and a full return of principal and interest expected. Trends and risk factors are neutral to favorable. 3. Average Risk- Performing investments requiring closer monitoring. Trends and risk factors show some deterioration. 4. High Risk/Delinquent/Potential for Loss- Underperforming investment with the potential of some interest loss but still expecting a positive return on investment. Trends and risk factors are negative. 5. Impaired/Defaulted/Loss Likely- Underperforming investment with expected loss of interest and some principal. The Company also considers qualitative and environmental factors, including, but not limited to, economic and business conditions, nature and volume of the loan portfolio, lending terms, volume and severity of past due loans, concentration of credit and changes in the level of such concentrations in its determination of the allowance for credit losses. Changes in the allowance for credit losses for the Company’s financial instruments are recorded in Increase/(decrease) for credit losses on the consolidated statements of operations with a corresponding offset to the financial instrument’s amortized cost recorded on the consolidated balance sheets, or as a component of Accounts payable and accrued expenses for unfunded loan commitments. The Company has elected to not measure an allowance for credit losses for accrued interest receivable as it is reversed against interest income when a loan or preferred equity investment is placed on nonaccrual status. Loans are charged off against the Increase/(decrease) for credit losses when all or a portion of the principal amount is determined to be uncollectible. Past due and nonaccrual status Loans are placed on nonaccrual status and considered non-performing when full payment of principal and interest is unpaid for 90 days or more or where reasonable doubt exists as to timely collection, unless the loan is both well secured and in the process of collection. Interest received on nonaccrual status loans are accounted for under the cost-recovery method, until qualifying for return to accrual. Upon restructuring the nonaccrual loan, the Company may return a loan to accrual status when repayment of principal and interest is reasonably assured. Troubled Debt Restructuring (“TDR”) The Company classifies an individual financial instrument as a TDR when it has a reasonable expectation that the financial instrument’s contractual terms will be modified in a manner that grants concession to the borrower who is experiencing financial difficulty. Concessions could include term extensions, payment deferrals, interest rate reductions, principal forgiveness, forbearance, or other actions designed to maximize the Company’s collection on the financial instrument. The Company determines the allowance for credit losses for financial instruments that are TDRs individually. 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 statements 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. The Company uses the specific identification method in determining the cost relief for real estate securities sold. Realized gains and losses from the sale of real estate securities are included in the Company’s consolidated statements of operations. AFS real estate securities which have experienced a decline in the fair value below their amortized cost basis (i.e., impairment) are evaluated each reporting period to determine whether the decline in fair value is due to credit-related factors. Any impairment that is not credit-related is recognized in other comprehensive income, while credit-related impairment is recognized as an allowance on the consolidated balance sheets with a corresponding adjustment on the consolidated statements of operations. If the Company intends to sell an impaired real estate security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount is recognized in the consolidated statements of operations with a corresponding adjustment to the security’s amortized cost basis. The Company analyzes the AFS security portfolio on a periodic basis for credit losses at the individual security level using the same criteria described above for those amortized cost financial assets subject to an allowance for credit losses including but not limited to; performance of the underlying assets in the security, borrower financial resources and investment in collateral, collateral type, credit ratings, project economics and geographic location as well as national and regional economic factors. The non-credit loss component of the unrealized loss within the Company’s AFS portfolio is recognized as an adjustment to the individual security’s asset balance with an offsetting entry to other comprehensive income in the consolidated balance sheets. 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. 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 (benefit) for the six months ended June 30, 2020 and June 30, 2019 were $(2.6) million and $1.6 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 do

Trends and risk factors since time of investment are favorable. 2 Performing consistent with expectations and a full return of principal and interest expected. Trends and risk factors are neutral to favorable. 3 Performing investments requiring closer monitoring. Trends and risk factors show some deterioration. 4 Underperforming investment with the potential of some interest loss but still expecting a positive return on investment. Trends and risk factors are negative. 5 Underperforming investment with expected loss of interest and some principal.

After evaluating the securities, we concluded that the unrealized losses reflected above were noncredit-related and would be recovered from the securities’ estimated future cash flows. We considered a number of factors in reaching this conclusion, including that we did not intend to sell the securities, it was not considered more likely than not that we would be forced to sell the securities prior to recovering our amortized cost, the portfolio is made up of investment grade securities of recent originations and higher tranches, and that there were no material credit events that would have caused us to otherwise conclude that we would not recover our cost. The allowance for credit losses is calculated using a discounted cash flow approach and is measured as the difference between the original cash flows expected to be collected to the revised cash flows expected to be collected discounted using the effective interest rate, limited by the amount that the fair value is less than the amortized cost basis. Significant judgment is used in projecting cash flows. As a result, actual income and/or credit losses could be materially different from what is currently projected and/or reported. The following table provides information on the amounts of gain/(loss) on the Company's real estate securities, CMBS, available-for-sale (dollars in thousands): Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Unrealized gain/(loss) available-for-sale securities $ 34,882 $ (65 ) $ (32,725 ) $ 80 Reclassification of net (gain)/loss on available-for-sale securities included in net income/(loss) 5,437 — 5,437 — Unrealized gain/(loss) available-for-sale securities, net of reclassification adjustment $ 40,319 $ (65 ) $ (27,288 ) $ 80 The amounts reclassified for net (gain)/loss on available-for-sale securities are included in the realized (gain)/loss on sale of real estate securities in the Company's consolidated statements of operations. The Company's unrealized gain/(loss) on available-for-sale securities is net of tax. Due to the Company's designation as a REIT, there was no tax impact on unrealized gain/(loss) on available-for-sale securities. The deterioration in fair value of real estate securities for both collateralized loan obligations and other securities as of June 30, 2020 can be attributed mainly to the market down-turn and volatility as a result of high unemployment and credit uncertainties related to the outbreak of COVID-19. Management currently does not have the intention to sell any of the real estate securities as of June 30, 2020 .

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/(loss) 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 three and six months ended June 30, 2020 and June 30, 2019 (in thousands, except share and per share data): Three Months Ended June 30, Six Months Ended June 30, Numerator 2020 2019 2020 2019 Net income $ 7,814 $ 14,526 $ 414 $ 34,416 Less: Preferred stock dividends 3,455 3,490 7,970 6,810 Net income/(loss) attributable to common shareholders (for basic and diluted earnings per share) 4,359 11,036 (7,556 ) 27,606 Denominator Weighted-average common shares outstanding for basic earnings per share 44,376,437 41,226,805 44,319,531 40,516,456 Effect of dilutive shares: Unvested restricted shares 12,943 12,743 — 12,915 Weighted-average common shares outstanding for diluted earnings per share 44,389,380 41,239,548 44,319,531 40,529,371 Basic earnings per share $ 0.10 $ 0.27 $ (0.17 ) $ 0.68 Diluted earnings per share $ 0.10 $ 0.27 $ (0.17 ) $ 0.68 For the six months ended June 30, 2020 potentially dilutive shares of 12,235 were excluded from the computation of diluted EPS because their effect would have been anti-dilutive. Anti-dilutive shares for the six months ended June 30, 2020 comprised of restricted stock units.

As of June 30, 2020 and December 31, 2019 , the Company had 40,514 and 40,500 shares of Series A Preferred Stock outstanding, respectively and 1,400 shares of Series C Preferred Stock outstanding.

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. In April 2020, the Company’s board of directors unanimously approved a transition in the timing of the dividend payments to holders of the Company’s common stock and Preferred Stock from a monthly to a quarterly basis. In response to the adverse economic impacts of the COVID-19 pandemic and uncertainties with respect to the future impacts thereof, in June of 2020 the Company’s board of directors declared for the second quarter of 2020: (i) a quarterly cash dividend of $0.275 per common share (equivalent to $1.10 per annum), and (ii) a quarterly cash dividend per share of Preferred Stock equivalent to the amount of distributions that would be paid upon a conversion of such share of Preferred Stock into common stock. For the six months ended June 30, 2020 and June 30, 2019 , the Company declared 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 June 30, 2020 and December 31, 2019 , the Company had declared but unpaid common stock distributions of $12.1 million and $5.4 million , respectively. Additionally, as of June 30, 2020 and December 31, 2019 , the Company had declared but unpaid Series A Preferred Stock distributions of $3.3 million and $1.5 million , respectively and $0.1 million and $0.1 million of Series C Preferred stock, respectively. These amounts are included in Distributions payable on the Company’s consolidated balance sheets. The Company distributed $21.2 million during the six months ended June 30, 2020 , comprised of $17.7 million in cash and $3.5 million in shares of common stock issued under the DRIP. The DRIP was temporarily suspended for the March 2020 dividend, but was reactivated for the second quarter 2020 dividend. The Company distributed $28.8 million during the six months ended June 30, 2019 , comprised of $21.9 million in cash and $6.9 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 June 30, 2020 is $16.97 . 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 June 30, 2020 : Number of Requests Number of Shares Repurchased Average Price per Share Cumulative as of December 31, 2019 5,878 3,542,267 $ 20.23 January 1 - January 31, 2020 (1) 1,170 373,135 18.56 February 1 - February 28, 2020 — — N/A March 1 - March 31, 2020 — — N/A April 1 - April 30, 2020 (1) — — N/A May 1 - May 31, 2020 — — N/A June 1 - June 30, 2020 — — N/A Cumulative as of June 30, 2020 7,048 3,915,402 $ 20.07 ________________________ (1) Reflects shares repurchased pursuant to repurchase requests submitted for the second semester of 2019, including 11,306 shares which for administrative reasons were processed in April 2020. The number of requests for January is inclusive of shares processed in April. Pursuant to the terms of the SRP, the Company is only authorized to repurchase up to the amount of proceeds reinvested through our DRIP during the applicable semester. As a result, redemption requests in the amount of 1,986,803 shares were not fulfilled for the second semester of 2019.

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, recorded in real estate securities, held-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 June 30, 2020 and December 31, 2019 , the Company obtained third party pricing for determining the fair value of each CMBS investment, resulting in a Level II classification. 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. Other real estate investments, measured at fair value on the consolidated balance sheets are valued using unobservable inputs. The Company engaged the services of a third party independent valuation firm to determine fair value of certain investments, including preferred equity 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 other real estate investments, 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 or liabilities. 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 no material transfers between levels within the fair value hierarchy for the period ended June 30, 2020 and 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 June 30, 2020 and December 31, 2019 (dollars in thousands): Total Level I Level II Level III June 30, 2020 Real estate securities, available-for-sale, measured at fair value $ 408,612 $ — $ 408,612 $ — Commercial mortgage loans, held-for-sale, measured at fair value 69,879 — — 69,879 Other real estate investments, measured at fair value 2,514 — — 2,514 Credit default swaps 133 — 133 — Total assets, at fair value $ 481,138 $ — $ 408,745 $ 72,393 Liabilities, at fair value Credit default swaps $ 179 $ — $ 179 $ — Interest rate swaps 4,410 — 4,410 — Total liabilities, at fair value $ 4,589 $ — $ 4,589 $ — December 31, 2019 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 fair value Credit Default Swaps $ 1,581 $ — $ 1,581 $ — Total liabilities, at fair value $ 1,581 $ — $ 1,581 $ — 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 June 30, 2020 and December 31, 2019 (dollars in thousands): Asset Category Fair Value Valuation Methodologies Unobservable Inputs (1) Weighted Average (2) Range June 30, 2020 Commercial mortgage loans, held-for-sale, measured at fair value $69,879 Discounted Cash Flow Yield 4.3% 3.3% - 5.6% Other real estate investments, measured at fair value 2,514 Discounted Cash Flow Yield 13.2% 12.7% - 13.7% December 31, 2019 Commercial mortgage loans, held-for-sale, measured at fair value $112,562 Discounted Cash Flow Yield 4.9% 4.7% - 5.2% Other real estate investments, measured at fair value 2,557 Discounted Cash Flow Yield 12.4% 11.4% - 13.4% ________________________ (1) In determining certain of these inputs, the Company evaluates a variety of factors including economic conditions, industry and market developments, market valuations of comparable companies and company specific developments including exit strategies and realization opportunities. 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 following table presents additional information about the Company’s financial instruments which are measured at fair value on a recurring basis as of June 30, 2020 and December 31, 2019 for which the Company has used Level III inputs to determine fair value (dollars in thousands): June 30, 2020 Commercial Mortgage Loans, held-for-sale, measured at fair value Other Real Estate Investments, measured at fair value Beginning balance, January 1, 2020 $ 112,562 $ 2,557 Transfers into Level III — — Total realized and unrealized gain/(loss) included in earnings: Realized gain/(loss) on sale of commercial mortgage loan, held-for-sale 9,166 — Unrealized gain/(loss) on commercial mortgage loans, held-for-sale and other real estate investments (339 ) (43 ) Net accretion — — Purchases 119,448 — Sales / paydowns (147,568 ) — Cash repayments/receipts — — Transfers out of Level III (23,390 ) — Ending Balance, June 30, 2020 $ 69,879 $ 2,514 December 31, 2019 Commercial Mortgage Loans, held-for-sale, measured at fair value Other Real Estate Investments, measured at fair value Beginning balance, January 1, 2019 $ 76,863 $ — Transfers into Level III — — Total realized and unrealized gain/(loss) included in earnings: Realized gain/(loss) on sale of commercial mortgage loan, held-for-sale 37,832 — Unrealized gain/(loss) on commercial mortgage loans, held-for-sale and other real estate investments 312 47 Net accretion — — Purchases 1,015,677 2,510 Sales / paydowns (1,008,050 ) — Cash repayments/receipts — — Transfers out of Level III (10,072 ) — Ending Balance, December 31, 2019 $ 112,562 $ 2,557 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 June 30, 2020 and December 31, 2019 (dollars in thousands): Level Carrying Amount (1) Fair Value June 30, 2020 Commercial mortgage loans, held for investment Asset III $ 2,494,914 $ 2,497,221 Collateralized loan obligations Liability III 1,697,666 1,659,430 Mortgage note payable Liability III 40,241 40,241 December 31, 2019 Commercial mortgage loans, held for investment Asset III $ 2,762,963 $ 2,784,650 Collateralized loan obligations Liability III 1,803,185 1,822,386 Mortgage note payable Liability III 29,167 29,167 ________________________ (1) The carrying value is gross of $26.2 million and $0.9 million of allowance for credit losses as of June 30, 2020 and December 31, 2019 , 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.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2020
Accounting Policies [Abstract]
Basis of Accounting	Basis of Accounting The Company's unaudited 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") for interim financial statements and pursuant to the requirements for reporting on Form 10-Q and Regulation S-X, as appropriate. Accordingly, the consolidated financial statements may not include all of the information and notes required by GAAP for annual consolidated financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto as of, and for the year ended December 31, 2019 , which are included in the Company's Annual Report on Form 10-K/A filed with the SEC on March 19, 2020 .
Use of Estimates	Use of Estimates 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 interim data includes all adjustments, of a normal and recurring nature, necessary for a fair statement of the results for the periods presented. The current period’s results of operations will not necessarily be indicative of results that ultimately may be achieved for the entire year or any subsequent interim periods. In response to the global coronavirus (COVID-19) pandemic, numerous countries, including the U.S., have declared national emergencies with respect to COVID-19 and certain jurisdictions, including those where our corporate headquarters and/or properties that secure our investments, or properties that we own, are located, have at times imposed “stay-at-home” guidelines or orders or other restrictions to help prevent its spread. The disruptive economic effects of the COVID-19 pandemic and government responses thereto have significantly impacted our estimates involving credit losses and fair values during the three and six months ended June 30, 2020 , including introducing a significant degree of uncertainty underlying those estimates.
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 sheets in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation.
Acquisition Expenses	Acquisition Expenses The Company capitalizes certain direct costs relating to 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 credit 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 commitment 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 commitment 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. 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 sheets. Interest income received on commercial mortgage loans held-for-sale, measured at fair value is recorded on the accrual basis of accounting and is included in interest income in the consolidated statements of operations. Acquisition expenses on originating these investments are expensed when incurred. Real estate owned Real estate owned (“REO”) represents real estate acquired by the Company through foreclosure, deed in lieu of foreclosure, or purchase. REO assets are carried at their estimated fair value at acquisition and are presented net of accumulated depreciation and impairment charges. The Company allocates the purchase price of acquired real estate assets based on the fair value of the acquired land, building, furniture, fixtures and equipment. 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. Real estate owned assets that are probable to be sold within one year are reported as held-for sale. Real estate owned assets classified as held-for-sale shall be measured at the lower of its carrying amount or fair value less cost to sell. Real estate owned assets shall not be depreciated or amortized while it is classified as held-for-sale. Interest and other expenses attributable to the liabilities of a disposal group classified as held-for-sale shall continue to be accrued. 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 June 30, 2020 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 sheets and amortized using the straight-line method over the contractual life of the lease.
Credit Losses	Credit Losses In June 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments-Credit Losses, which amends the credit impairment model for financial instruments. The Company adopted ASU 2016-13 on January 1, 2020. Following our adoption of ASU 2016-13, our previous incurred loss model was replaced with a lifetime current expected credit loss (“CECL”) model for financial instruments carried at amortized cost and off-balance sheet credit exposures, such as loans, loan commitments, held-to-maturity (“HTM”) debt securities, financial guarantees, net investments in leases, reinsurance and trade receivables, which will generally result in earlier recognition of allowance for losses. For available for sale (“AFS”) debt securities, unrealized credit losses are recognized as allowances rather than reductions in amortized cost basis and elimination of the other than temporary impairment concept will result in more frequent estimation of credit losses. The accounting model for purchased credit impaired loans and debt securities has been simplified, including elimination of some of the asymmetrical treatment between credit losses and credit recoveries, to be consistent with the CECL model for originated and purchased non-credit impaired assets. The adopted model for ASC 326 as it applies to HTM and AFS securities, encompassing the beneficial interest model for securities that are not of high credit quality, has been clarified to include the effective interest method as a basis for the projection of cash collections method in connection with the newly adopted impairment models for HTM and AFS debt securities under ASC 326 when securities are not of high credit quality. Upon adoption of ASU 2016-13 on January 1, 2020, we recorded an additional allowance for credit losses for our outstanding loans and unfunded loan commitments of $7.8 million , or $0.18 per share, which was 0.27% of the aggregate commitment amount of the Company’s loan portfolio at December 31, 2019. Pre-adoption Transition Adjustment Post-adjustment Assets Commercial mortgage loans, held for investment, net of allowance 2,762,042 (7,211 ) 2,754,831 Liabilities Accounts payable and accrued expenses (1) 10,925 (550 ) 10,375 Equity Accumulated deficit (85,968 ) (7,761 ) (93,729 ) ________________________ (1) Includes allowance associated with unfunded loan commitment. The following discussion highlights changes to the Company’s accounting policies as a result of this adoption. Allowance for credit losses The allowance for credit losses for the Company’s financial instruments carried at amortized cost and off-balance sheet credit exposures, such as loans held for investment and unfunded loan commitments represents a lifetime estimate of expected credit losses. Factors considered by the Company when determining the allowance for credit losses reserve include loan-specific characteristics such as loan-to-value (“LTV”) ratio, vintage year, loan term, property type, occupancy and geographic location, financial performance of the borrower, expected payments of principal and interest, as well as internal or external information relating to past events, current conditions and reasonable and supportable forecasts. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist for multiple financial instruments. If similar risk characteristics do not exist, the Company measures the allowance for credit losses on an individual instrument basis. The determination of whether a particular financial instrument should be included in a pool can change over time. If a financial asset’s risk characteristics change, the Company evaluates whether it is appropriate to continue to keep the financial instrument in its existing pool or evaluate it individually. In measuring the allowance for credit losses for financial instruments including our unfunded loan commitments that share similar risk characteristics, the Company primarily applies a probability of default (“PD”)/loss given default (“LGD”) model for instruments that are collectively assessed, whereby the allowance for credit losses is calculated as the product of PD, LGD and exposure at default (“EAD”). The Company’s model principally utilizes historical loss rates derived from a commercial mortgage backed securities database with historical losses from 1998 to 2020 provided by a reputable third party, forecasting the loss parameters using a scenario-based statistical approach over a reasonable and supportable forecast period of twelve months, followed by an immediate reversion to average historical losses. For financial instruments assessed on an individual basis, including when it is probable that the Company will be unable to collect the full payment of principal and interest on the instrument, the Company applies a discounted cash flow (“DCF”) methodology. For financial instruments where the borrower is experiencing financial difficulty based on the Company’s assessment at the reporting date and the repayment is expected to be provided substantially through the operation or sale of the collateral, the Company may elect to use as a practical expedient the fair value of the collateral at the reporting date when determining the allowance for credit losses. In developing the allowance for credit losses for its loans held for investment, 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, using similar factors as those in developing the allowance for credit losses. 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. Risk rating categories range from "1" to "5" with "1" representing the lowest risk of loss and "5" representing the highest risk of loss with the ratings updated quarterly. At the time of origination or purchase, loans held for investment are ranked as a “2” and will move accordingly going forward based on the ratings which are defined as follows: 1. Very Low Risk- Investment exceeding fundamental performance expectations and/or capital gain expected. Trends and risk factors since time of investment are favorable. 2. Low Risk- Performing consistent with expectations and a full return of principal and interest expected. Trends and risk factors are neutral to favorable. 3. Average Risk- Performing investments requiring closer monitoring. Trends and risk factors show some deterioration. 4. High Risk/Delinquent/Potential for Loss- Underperforming investment with the potential of some interest loss but still expecting a positive return on investment. Trends and risk factors are negative. 5. Impaired/Defaulted/Loss Likely- Underperforming investment with expected loss of interest and some principal. The Company also considers qualitative and environmental factors, including, but not limited to, economic and business conditions, nature and volume of the loan portfolio, lending terms, volume and severity of past due loans, concentration of credit and changes in the level of such concentrations in its determination of the allowance for credit losses. Changes in the allowance for credit losses for the Company’s financial instruments are recorded in Increase/(decrease) for credit losses on the consolidated statements of operations with a corresponding offset to the financial instrument’s amortized cost recorded on the consolidated balance sheets, or as a component of Accounts payable and accrued expenses for unfunded loan commitments. The Company has elected to not measure an allowance for credit losses for accrued interest receivable as it is reversed against interest income when a loan or preferred equity investment is placed on nonaccrual status. Loans are charged off against the Increase/(decrease) for credit losses when all or a portion of the principal amount is determined to be uncollectible. Past due and nonaccrual status Loans are placed on nonaccrual status and considered non-performing when full payment of principal and interest is unpaid for 90 days or more or where reasonable doubt exists as to timely collection, unless the loan is both well secured and in the process of collection. Interest received on nonaccrual status loans are accounted for under the cost-recovery method, until qualifying for return to accrual. Upon restructuring the nonaccrual loan, the Company may return a loan to accrual status when repayment of principal and interest is reasonably assured. Troubled Debt Restructuring (“TDR”) The Company classifies an individual financial instrument as a TDR when it has a reasonable expectation that the financial instrument’s contractual terms will be modified in a manner that grants concession to the borrower who is experiencing financial difficulty. Concessions could include term extensions, payment deferrals, interest rate reductions, principal forgiveness, forbearance, or other actions designed to maximize the Company’s collection on the financial instrument. The Company determines the allowance for credit losses for financial instruments that are TDRs individually.
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 statements 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. The Company uses the specific identification method in determining the cost relief for real estate securities sold. Realized gains and losses from the sale of real estate securities are included in the Company’s consolidated statements of operations. AFS real estate securities which have experienced a decline in the fair value below their amortized cost basis (i.e., impairment) are evaluated each reporting period to determine whether the decline in fair value is due to credit-related factors. Any impairment that is not credit-related is recognized in other comprehensive income, while credit-related impairment is recognized as an allowance on the consolidated balance sheets with a corresponding adjustment on the consolidated statements of operations. If the Company intends to sell an impaired real estate security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount is recognized in the consolidated statements of operations with a corresponding adjustment to the security’s amortized cost basis. The Company analyzes the AFS security portfolio on a periodic basis for credit losses at the individual security level using the same criteria described above for those amortized cost financial assets subject to an allowance for credit losses including but not limited to; performance of the underlying assets in the security, borrower financial resources and investment in collateral, collateral type, credit ratings, project economics and geographic location as well as national and regional economic factors. The non-credit loss component of the unrealized loss within the Company’s AFS portfolio is recognized as an adjustment to the individual security’s asset balance with an offsetting entry to other comprehensive income in the consolidated balance sheets.
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.
Deferred Financing Cost	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	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	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.
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 (benefit) for the six months ended June 30, 2020 and June 30, 2019 were $(2.6) million and $1.6 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 and calculates 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”). Each outstanding share of 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.
Accounting Pronouncements Not Yet Adopted	Accounting Pronouncements Not Yet Adopted On March 12, 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional expedients and exceptions to the US GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance is effective upon issuance and generally can be applied through December 31, 2022. The Company has not adopted any of the optional expedients or exceptions through June 30, 2020, but will continue to evaluate the possible adoption of any such expedients or exceptions during the effective period as circumstances evolve.
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, recorded in real estate securities, held-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 June 30, 2020 and December 31, 2019 , the Company obtained third party pricing for determining the fair value of each CMBS investment, resulting in a Level II classification. 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. Other real estate investments, measured at fair value on the consolidated balance sheets are valued using unobservable inputs. The Company engaged the services of a third party independent valuation firm to determine fair value of certain investments, including preferred equity 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 other real estate investments, 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.
