Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared on the accrual basis of accounting in conformity with United States generally accepted accounting principles (“GAAP”) and include the accounts of the Company, the consolidated variable interest entities (“VIEs”) that the Company controls and of which the Company is the primary beneficiary, and the Company’s wholly-owned subsidiaries. The consolidated financial statements reflect all adjustments and reclassifications that, in the opinion of management, are necessary for the fair presentation of the Company’s results of operations and financial condition as of and for the periods presented. All intercompany balances and transactions have been eliminated.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosures. As of the filing date of this Annual Report, there is a continued outbreak of the novel Coronavirus pandemic (“COVID-19”), for which the World Health Organization has declared a global pandemic, the United States has declared a national emergency and every state in the United States is under a federal disaster declaration. Many states, including those in which the Company and its borrowers operate, have issued orders requiring the closure of, or certain restrictions on the operation of, non-essential businesses and/or requiring residents to stay at home. The COVID-19 pandemic and preventative measures taken to contain or mitigate its spread have caused, and are continuing to cause, business shutdowns or the re-introduction of business shutdowns, cancellations of events and restrictions on travel, significant reductions in demand for certain goods and services, reductions in business activity and financial transactions, supply chain interruptions and overall economic and financial market instability both globally and in the United States. While several countries, as well as certain states in the United States, have relaxed the public health restrictions with a view to partially or fully reopen their economies, recurring COVID-19 outbreaks have led to the re-introduction of such restrictions in certain states in the United States and globally and could continue to lead to the re-introduction of such restrictions elsewhere. Additionally, in December 2020, the U.S. Food and Drug Administration authorized certain vaccines for emergency use. However, it remains unclear how quickly the vaccines will be distributed nationwide and globally or when “herd immunity” will be achieved and the restrictions that were imposed to slow the spread of the virus will be lifted entirely. The delay in distributing the vaccines could lead people to continue to self-isolate and not participate in the economy at pre-pandemic levels for a prolonged period of time. Even after the COVID-19 pandemic subsides, the U.S. economy and most other major global economies may continue to experience a recession, and we anticipate our business and operations could be materially adversely affected by a prolonged recession in the United States. The Company believes the estimates and assumptions underlying its consolidated financial statements are reasonable and supportable based on the information available as of December 31, 2020, however, uncertainty over the ultimate impact the COVID-19 pandemic will have on the global economy and the Company’s business, makes any estimates and assumptions as of December 31, 2020 inherently less certain than they would be absent the current and potential impacts of the COVID-19 pandemic. Actual results could differ from those estimates.
Variable Interest Entities	Variable Interest Entities The Company evaluates all of its interests in VIEs for consolidation. When the Company’s interests are determined to be variable interests, the Company assesses whether it is deemed to be the primary beneficiary of the VIE. The primary beneficiary of a VIE is required to consolidate the VIE. Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, Consolidation, defines the primary beneficiary as the party that has both (i) the power to direct the activities of the VIE that most significantly impact its economic performance, and (ii) the obligation to absorb losses and the right to receive benefits from the VIE which could be potentially significant. The Company considers its variable interests, as well as any variable interests of its related parties in making this determination. Where both of these factors are present, the Company is deemed to be the primary beneficiary and it consolidates the VIE. Where either one of these factors is not present, the Company is not the primary beneficiary and it does not consolidate the VIE. To assess whether the Company has the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, the Company considers all facts and circumstances, including its role in establishing the VIE and its ongoing rights and responsibilities. This assessment includes first, identifying the activities that most significantly impact the VIE’s economic performance; and second, identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE or have the right to unilaterally remove those decision makers are deemed to have the power to direct the activities of a VIE. To assess whether the Company has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, the Company considers all of its economic interests, including debt and equity investments, servicing fees, and other arrangements deemed to be variable interests in the VIE. This assessment requires that the Company applies judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Factors considered in assessing significance include: the design of the VIE, including its capitalization structure; subordination of interests; payment priority; relative share of interests held across various classes within the VIE’s capital structure; and the reasons why the interests are held by the Company. For VIEs of which the Company is determined to be the primary beneficiary, all of the underlying assets, liabilities, equity, revenue and expenses of the structures are consolidated into the Company’s consolidated financial statements. The Company performs an ongoing reassessment of: (1) whether any entities previously evaluated under the majority voting interest framework have become VIEs, based on certain events, and therefore are subject to the VIE consolidation framework, and (2) whether changes in the facts and circumstances regarding its involvement with a VIE cause the Company’s consolidation conclusion regarding the VIE to change.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents include funds on deposit with financial institutions, including demand deposits with financial institutions. Cash and short‑term investments with an original maturity of three months or less when acquired are considered cash and cash equivalents for the purpose of the consolidated balance sheets and statements of cash flows. Restricted cash includes deposits required under certain Secured Funding Agreements (each individually defined in Note 6 included in these consolidated financial statements).
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and restricted cash, loans held for investment and interest receivable. The Company places its cash and cash equivalents with financial institutions and, at times, cash held may exceed the Federal Deposit Insurance Corporation insured limit. The Company has exposure to credit risk on its loans held for investment. The Company and the Company’s Manager seek to manage credit risk by performing due diligence prior to origination or acquisition and through the use of non‑recourse financing, when and where available and appropriate.
Loans Held for Investment	Loans Held for Investment The Company originates CRE debt and related instruments generally to be held for investment. Loans that are held for investment are carried at cost, net of unamortized loan fees and origination costs (the “carrying value”). Loans are generally collateralized by real estate. The extent of any credit deterioration associated with the performance and/or value of the underlying collateral property and the financial and operating capability of the borrower could impact the expected amounts received. The Company monitors performance of its loans held for investment portfolio under the following methodology: (1) borrower review, which analyzes the borrower’s ability to execute on its original business plan, reviews its financial condition, assesses pending litigation and considers its general level of responsiveness and cooperation; (2) economic review, which considers underlying collateral (i.e. leasing performance, unit sales and cash flow of the collateral and its ability to cover debt service, as well as the residual loan balance at maturity); (3) property review, which considers current environmental risks, changes in insurance costs or coverage, current site visibility, capital expenditures and market perception; and (4) market review, which analyzes the collateral from a supply and demand perspective of similar property types, as well as from a capital markets perspective. Such analyses are completed and reviewed by asset management and finance personnel who utilize various data sources, including periodic financial data such as property occupancy, tenant profile, rental rates, operating expenses, and the borrower’s exit plan, among other factors. Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more or when there is reasonable doubt that principal or interest will be collected in full. Accrued and unpaid interest is generally reversed against interest income in the period the loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding the borrower’s ability to make pending principal and interest payments. Non-accrual loans are restored to accrual status when past due principal and interest are paid and, in management’s judgment, are likely to remain current. The Company may make exceptions to placing a loan on non-accrual status if the loan has sufficient collateral value and is in the process of collection. Loan balances that are deemed to be uncollectible are written off as a realized loss and are deducted from the current expected credit loss reserve. The write-offs are recorded in the period in which the loan balance is deemed uncollectible based on management’s judgment.
Current Expected Credit Losses	Current Expected Credit Losses In June 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The standard replaced the incurred loss impairment methodology pursuant to GAAP with a methodology that reflects current expected credit losses (“CECL”) on both the outstanding balances and unfunded commitments on loans held for investment and requires consideration of a broader range of historical experience adjusted for current conditions and reasonable and supportable forecast information to inform credit loss estimates (the “CECL Reserve”). ASU No. 2016-13 was effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. ASU No. 2016-13 was adopted by the Company on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of January 1, 2020. Subsequent period increases and decreases to expected credit losses impact earnings and are recorded within provision for current expected credit losses in the Company’s consolidated statements of operations. The CECL Reserve related to outstanding balances on loans held for investment required under ASU No. 2016-13 is a valuation account that is deducted from the amortized cost basis of the Company’s loans held for investment in the Company’s consolidated balance sheets. The CECL Reserve related to unfunded commitments on loans held for investment is recorded within other liabilities in the Company's consolidated balance sheets. See Note 4 included in these consolidated financial statements for CECL related disclosures.
Loans Held for Sale	Loans Held for Sale Although the Company generally holds its target investments as long-term investments, the Company may occasionally classify some of its investments as held for sale. Investments held for sale are carried at fair value within loans held for sale, at fair value in the Company’s consolidated balance sheets, with changes in fair value recorded through earnings.
Real Estate Owned	Real Estate Owned Real estate 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. The cost of ordinary repairs and maintenance are expensed as incurred. Real estate assets are evaluated for indicators of impairment on a quarterly basis. Factors that the Company may consider in its impairment analysis include, among others: (1) significant underperformance relative to historical or anticipated operating results; (2) significant negative industry or economic trends; (3) costs necessary to extend the life or improve the real estate asset; (4) significant increase in competition; and (5) ability to hold and dispose of the real estate asset in the ordinary course of business. A real estate asset is considered impaired when the sum of estimated future undiscounted cash flows expected to be generated by the real estate asset over the estimated remaining holding period is less than the carrying amount of such real estate asset. Cash flows include operating cash flows and anticipated capital proceeds generated by the real estate asset. An impairment charge is recorded equal to the excess of the carrying value of the real estate asset over the fair value. When determining the fair value of a real estate asset, the Company makes certain assumptions including, but not limited to, consideration of projected operating cash flows, comparable selling prices and projected cash flows from the eventual disposition of the real estate asset based upon the Company’s estimate of a capitalization rate and discount rate. The Company reviews its real estate assets, from time to time, in order to determine whether to sell such assets. Real estate assets are classified as held for sale when the Company commits to a plan to sell the asset, when the asset is being marketed for sale at a reasonable price and the sale of the asset is probable and the transfer of the asset is expected to qualify for recognition as a completed sale within one year. Real estate assets that are held for sale are carried at the lower of the asset’s carrying amount or its fair value less costs to sell.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs under the Company’s indebtedness are capitalized and amortized over the term of the respective debt instrument. Unamortized debt issuance costs are expensed when the associated debt is repaid prior to maturity. Debt issuance costs related to debt securitizations are capitalized and amortized over the term of the underlying loans using the effective interest method. When an underlying loan is prepaid in a debt securitization and the outstanding principal balance of the securitization debt is reduced, the related unamortized debt issuance costs are charged to expense based on a pro‑rata share of the debt issuance costs being allocated to the specific loans that were prepaid. Amortization of debt issuance costs is included within interest expense, except as noted below, in the Company’s consolidated statements of operations while the unamortized balance on (i) Secured Funding Agreements (each individually defined in Note 6 included in these consolidated financial statements) is included within other assets and (ii) Notes Payable, the Secured Term Loan (each defined in Note 6 included in these consolidated financial statements) and Secured Borrowings (defined in Note 7 included in these consolidated financial statements) and debt securitizations are each included as a reduction to the carrying amount of the liability, in the Company’s consolidated balance sheets. Amortization of debt issuance costs for the note payable on the hotel property that is recognized as real estate owned in the Company’s consolidated balance sheets (see Note 6 included in these consolidated financial statements for additional information on the note payable) is included within expenses from real estate owned in the Company’s consolidated statements of operations. The original issue discount (“OID”) on amounts drawn under the Company’s Secured Term Loan represents a discount to the face amount of the drawn debt obligations. The OID is amortized over the term of the Secured Term Loan using the effective interest method and is included within interest expense in the Company’s consolidated statements of operations while the unamortized balance is included as a reduction to the carrying amount of the Secured Term Loan in the Company’s consolidated balance sheets.
Revenue Recognition	Revenue Recognition Interest income is accrued based on the outstanding principal amount and the contractual terms of each loan. For loans held for investment, the origination fees, contractual exit fees and direct loan origination costs are also recognized in interest income over the initial loan term as a yield adjustment using the effective interest method. Revenue from real estate owned represents revenue associated with the operations of a hotel property classified as real estate owned. Revenue from the operation of the hotel property is recognized when guestrooms are occupied, services have been rendered or fees have been earned. Revenues are recorded net of any discounts and sales and other taxes collected from customers. Revenues consist of room sales, food and beverage sales and other hotel revenues.
Net Interest Margin and Interest Expense	Net Interest Margin and Interest Expense Net interest margin in the Company’s consolidated statements of operations serves to measure the performance of the Company’s loans as compared to its use of debt leverage. The Company includes interest income from its loans and interest expense related to its Secured Funding Agreements, Notes Payable, securitization debt, the Secured Term Loan (each individually defined in Note 6 included in these consolidated financial statements) and Secured Borrowings (defined in Note 7 included in these consolidated financial statements) in net interest margin.
Income Taxes	Income Taxes The Company has elected and qualified for taxation as a REIT commencing with its taxable year ended December 31, 2012. As a result of the Company’s REIT qualification and its distribution policy, the Company does not generally pay United States federal corporate level income taxes. Many of the REIT requirements, however, are highly technical and complex. To continue to qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that the Company distributes annually to its stockholders at least 90% of the Company’s REIT taxable income prior to the deduction for dividends paid. To the extent that the Company distributes less than 100% of its REIT taxable income in any tax year (taking into account any distributions made in a subsequent tax year under Sections 857(b)(9) or 858 of the Code), the Company will pay tax at regular corporate rates on that undistributed portion. Furthermore, if the Company distributes less than the sum of 1) 85% of its ordinary income for the calendar year, 2) 95% of its capital gain net income for the calendar year, and 3) any undistributed shortfall from its prior calendar year (the “Required Distribution”) to its stockholders during any calendar year (including any distributions declared by the last day of the calendar year but paid in the subsequent year), then it is required to pay a non-deductible excise tax equal to 4% of any shortfall between the Required Distribution and the amount that was actually distributed. The 90% distribution requirement does not require the distribution of net capital gains. However, if the Company elects to retain any of its net capital gain for any tax year, it must notify its stockholders and pay tax at regular corporate rates on the retained net capital gain. The stockholders must include their proportionate share of the retained net capital gain in their taxable income for the tax year, and they are deemed to have paid the REIT’s tax on their proportionate share of the retained capital gain. Furthermore, such retained capital gain may be subject to the nondeductible 4% excise tax. If it is determined that the Company’s estimated current year taxable income will be in excess of estimated dividend distributions (including capital gain dividend) for the current year from such income, the Company accrues excise tax on estimated excess taxable income as such taxable income is earned. The annual expense is calculated in accordance with applicable tax regulations. Excise tax expense is included in the line item income tax expense, including excise tax in the consolidated statements of operations included in this annual report on Form 10-K. The Company formed a wholly-owned subsidiary, ACRC Lender W TRS LLC (“ACRC W TRS”), in December 2013 in order to issue and hold certain loans intended for sale. The Company also formed a wholly-owned subsidiary, ACRC 2017-FL3 TRS LLC (“FL3 TRS”), in March 2017 in order to hold a portion of the CLO Securitization (as defined below), including the portion that generates excess inclusion income. Additionally, the Company also formed a wholly-owned subsidiary, ACRC WM Tenant LLC (“ACRC WM”), in March 2019 in order to lease the hotel property classified as real estate owned, which was acquired on March 8, 2019. Entity classification elections to be taxed as a corporation and taxable REIT subsidiary (“TRS”) elections were made with respect to ACRC W TRS, FL3 TRS and ACRC WM. A TRS is an entity taxed as a corporation that has not elected to be taxed as a REIT, in which a REIT directly or indirectly holds equity, and that has made a joint election with such REIT to be treated as a TRS. A TRS generally may engage in any business, including investing in assets and engaging in activities that could not be held or conducted directly by the Company without jeopardizing its qualification as a REIT. A TRS is subject to applicable United States federal, state and local income tax on its taxable income. In addition, as a REIT, the Company also may be subject to a 100% excise tax on certain transactions between it and its TRS that are not conducted on an arm’s-length basis. For financial reporting purposes, a provision for current and deferred taxes has been established for the portion of the Company’s GAAP consolidated earnings recognized by ACRC W TRS, FL3 TRS and ACRC WM. The income tax provision is included in the line item income tax expense, including excise tax in the consolidated statements of operations included in this annual report on Form 10-K. FASB ASC Topic 740, Income Taxes (“ASC 740”), prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company has analyzed its various federal and state filing positions and believes that its income tax filing positions and deductions are well documented and supported. As of December 31, 2020 and 2019, based on the Company’s evaluation, there is no reserve for any uncertain income tax positions. ACRC W TRS, FL3 TRS and ACRC WM recognize interest and penalties, if any, related to unrecognized tax benefits within income tax expense in the consolidated statements of operations. Accrued interest and penalties, if any, are included within other liabilities in the consolidated balance sheets.
Comprehensive Income	Comprehensive Income For the years ended December 31, 2020, 2019 and 2018, comprehensive income equaled net income; therefore, a separate consolidated statement of comprehensive income is not included in the accompanying consolidated financial statements.
Share-based Compensation	Stock-Based Compensation The Company recognizes the cost of stock‑based compensation, which is included within general and administrative expenses in the Company’s consolidated statements of operations. The fair value of the time vested restricted stock or restricted stock units (“RSUs”) granted is recorded to expense on a straight‑line basis over the vesting period for the award, with an offsetting increase in stockholders’ equity. For grants to directors and officers and employees of the Manager, the fair value is determined based upon the market price of the stock on the grant date.
Earnings per Share	Earnings per ShareThe Company calculates basic earnings (loss) per share by dividing net income (loss) allocable to common stockholders for the period by the weighted average shares of common stock outstanding for that period after consideration of the earnings (loss) allocated to the Company’s restricted stock, which are participating securities as defined in GAAP. Diluted earnings (loss) per share takes into effect any dilutive instruments, such as restricted stock, RSUs and convertible debt, except when doing so would be anti‑dilutive.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 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 optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. ASU No. 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements.

SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2020

The accompanying consolidated financial statements have been prepared on the accrual basis of accounting in conformity with United States generally accepted accounting principles (“GAAP”) and include the accounts of the Company, the consolidated variable interest entities (“VIEs”) that the Company controls and of which the Company is the primary beneficiary, and the Company’s wholly-owned subsidiaries. The consolidated financial statements reflect all adjustments and reclassifications that, in the opinion of management, are necessary for the fair presentation of the Company’s results of operations and financial condition as of and for the periods presented. All intercompany balances and transactions have been eliminated.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosures. As of the filing date of this Annual Report, there is a continued outbreak of the novel Coronavirus pandemic (“COVID-19”), for which the World Health Organization has declared a global pandemic, the United States has declared a national emergency and every state in the United States is under a federal disaster declaration. Many states, including those in which the Company and its borrowers operate, have issued orders requiring the closure of, or certain restrictions on the operation of, non-essential businesses and/or requiring residents to stay at home. The COVID-19 pandemic and preventative measures taken to contain or mitigate its spread have caused, and are continuing to cause, business shutdowns or the re-introduction of business shutdowns, cancellations of events and restrictions on travel, significant reductions in demand for certain goods and services, reductions in business activity and financial transactions, supply chain interruptions and overall economic and financial market instability both globally and in the United States. While several countries, as well as certain states in the United States, have relaxed the public health restrictions with a view to partially or fully reopen their economies, recurring COVID-19 outbreaks have led to the re-introduction of such restrictions in certain states in the United States and globally and could continue to lead to the re-introduction of such restrictions elsewhere.

Additionally, in December 2020, the U.S. Food and Drug Administration authorized certain vaccines for emergency use. However, it remains unclear how quickly the vaccines will be distributed nationwide and globally or when “herd immunity” will be achieved and the restrictions that were imposed to slow the spread of the virus will be lifted entirely. The delay in distributing the vaccines could lead people to continue to self-isolate and not participate in the economy at pre-pandemic levels for a prolonged period of time. Even after the COVID-19 pandemic subsides, the U.S. economy and most other major global economies may continue to experience a recession, and we anticipate our business and operations could be materially adversely affected by a prolonged recession in the United States. The Company believes the estimates and assumptions underlying its consolidated financial statements are reasonable and supportable based on the information available as of December 31, 2020, however, uncertainty over the ultimate impact the COVID-19 pandemic will have on the global economy and the Company’s business, makes any estimates and assumptions as of December 31, 2020 inherently less certain than they would be absent the current and potential impacts of the COVID-19 pandemic. Actual results could differ from those estimates.

Variable Interest Entities

The Company evaluates all of its interests in VIEs for consolidation. When the Company’s interests are determined to be variable interests, the Company assesses whether it is deemed to be the primary beneficiary of the VIE. The primary beneficiary of a VIE is required to consolidate the VIE. Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, Consolidation, defines the primary beneficiary as the party that has both (i) the power to direct the activities of the VIE that most significantly impact its economic performance, and (ii) the obligation to absorb losses and the right to receive benefits from the VIE which could be potentially significant. The Company considers its variable interests, as well as any variable interests of its related parties in making this determination. Where both of these factors are present, the Company is deemed to be the primary beneficiary and it consolidates the VIE. Where either one of these factors is not present, the Company is not the primary beneficiary and it does not consolidate the VIE.

To assess whether the Company has the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, the Company considers all facts and circumstances, including its role in establishing the VIE and its ongoing rights and responsibilities. This assessment includes first, identifying the activities that most significantly impact the VIE’s economic performance; and second, identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE or have the right to unilaterally remove those decision makers are deemed to have the power to direct the activities of a VIE.

To assess whether the Company has the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, the Company considers all of its economic interests, including debt and equity investments, servicing fees, and other arrangements deemed to be variable interests in the VIE. This assessment requires that the Company applies judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Factors considered in assessing significance include: the design of the VIE, including its capitalization structure; subordination of interests; payment priority; relative share of interests held across various classes within the VIE’s capital structure; and the reasons why the interests are held by the Company.

For VIEs of which the Company is determined to be the primary beneficiary, all of the underlying assets, liabilities, equity, revenue and expenses of the structures are consolidated into the Company’s consolidated financial statements.

The Company performs an ongoing reassessment of: (1) whether any entities previously evaluated under the majority voting interest framework have become VIEs, based on certain events, and therefore are subject to the VIE consolidation framework, and (2) whether changes in the facts and circumstances regarding its involvement with a VIE cause the Company’s consolidation conclusion regarding the VIE to change.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include funds on deposit with financial institutions, including demand deposits with financial institutions. Cash and short‑term investments with an original maturity of three months or less when acquired are considered cash and cash equivalents for the purpose of the consolidated balance sheets and statements of cash flows.

Restricted cash includes deposits required under certain Secured Funding Agreements (each individually defined in Note 6 included in these consolidated financial statements).

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and restricted cash, loans held for investment and interest receivable. The Company places its cash and cash equivalents with financial institutions and, at times, cash held may exceed the Federal Deposit Insurance Corporation insured limit. The Company has exposure to credit risk on its loans held for investment. The Company and the Company’s Manager seek to manage credit risk by performing due diligence prior to origination or acquisition and through the use of non‑recourse financing, when and where available and appropriate.

Loans Held for Investment

The Company originates CRE debt and related instruments generally to be held for investment. Loans that are held for investment are carried at cost, net of unamortized loan fees and origination costs (the “carrying value”). Loans are generally collateralized by real estate. The extent of any credit deterioration associated with the performance and/or value of the underlying collateral property and the financial and operating capability of the borrower could impact the expected amounts received. The Company monitors performance of its loans held for investment portfolio under the following methodology: (1) borrower review, which analyzes the borrower’s ability to execute on its original business plan, reviews its financial condition, assesses pending litigation and considers its general level of responsiveness and cooperation; (2) economic review, which considers underlying collateral (i.e. leasing performance, unit sales and cash flow of the collateral and its ability to cover debt service, as well as the residual loan balance at maturity); (3) property review, which considers current environmental risks, changes in insurance costs or coverage, current site visibility, capital expenditures and market perception; and (4) market review, which analyzes the collateral from a supply and demand perspective of similar property types, as well as from a capital markets perspective. Such analyses are completed and reviewed by asset management and finance personnel who utilize various data sources, including periodic financial data such as property occupancy, tenant profile, rental rates, operating expenses, and the borrower’s exit plan, among other factors.

Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more or when there is reasonable doubt that principal or interest will be collected in full. Accrued and unpaid interest is generally reversed against interest income in the period the loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management’s judgment regarding the borrower’s ability to make pending principal and interest payments. Non-accrual loans are restored to accrual status when past due principal and interest are paid and, in management’s judgment, are likely to remain current. The Company may make exceptions to placing a loan on non-accrual status if the loan has sufficient collateral value and is in the process of collection.

Loan balances that are deemed to be uncollectible are written off as a realized loss and are deducted from the current expected credit loss reserve. The write-offs are recorded in the period in which the loan balance is deemed uncollectible based on management’s judgment.

Current Expected Credit Losses

In June 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The standard replaced the incurred loss impairment methodology pursuant to GAAP with a methodology that reflects current expected credit losses (“CECL”) on both the outstanding balances and unfunded commitments on loans held for investment and requires consideration of a broader range of historical experience adjusted for current conditions and reasonable and supportable forecast information to inform credit loss estimates (the “CECL Reserve”). ASU No. 2016-13 was effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. ASU No. 2016-13 was adopted by the Company on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of January 1, 2020. Subsequent period increases and decreases to expected credit losses impact earnings and are recorded within provision for current expected credit losses in the Company’s consolidated statements of operations. The CECL Reserve related to outstanding balances on loans held for investment required under ASU No. 2016-13 is a valuation account that is deducted from the amortized cost basis of the Company’s loans held for investment in the Company’s consolidated balance sheets. The CECL Reserve related to unfunded commitments on loans held for investment is recorded within other liabilities in the Company's consolidated balance sheets. See Note 4 included in these consolidated financial statements for CECL related disclosures.

Loans Held for Sale

Although the Company generally holds its target investments as long-term investments, the Company may occasionally classify some of its investments as held for sale. Investments held for sale are carried at fair value within loans held for sale, at fair value in the Company’s consolidated balance sheets, with changes in fair value recorded through earnings.

Real Estate Owned

Real estate 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. The cost of ordinary repairs and maintenance are expensed as incurred.

Real estate assets are evaluated for indicators of impairment on a quarterly basis. Factors that the Company may consider in its impairment analysis include, among others: (1) significant underperformance relative to historical or anticipated operating results; (2) significant negative industry or economic trends; (3) costs necessary to extend the life or improve the real estate asset; (4) significant increase in competition; and (5) ability to hold and dispose of the real estate asset in the ordinary course of business. A real estate asset is considered impaired when the sum of estimated future undiscounted cash flows expected to be generated by the real estate asset over the estimated remaining holding period is less than the carrying amount of such real estate asset. Cash flows include operating cash flows and anticipated capital proceeds generated by the real estate asset. An impairment charge is recorded equal to the excess of the carrying value of the real estate asset over the fair value. When determining the fair value of a real estate asset, the Company makes certain assumptions including, but not limited to, consideration of projected operating cash flows, comparable selling prices and projected cash flows from the eventual disposition of the real estate asset based upon the Company’s estimate of a capitalization rate and discount rate.

The Company reviews its real estate assets, from time to time, in order to determine whether to sell such assets. Real estate assets are classified as held for sale when the Company commits to a plan to sell the asset, when the asset is being marketed for sale at a reasonable price and the sale of the asset is probable and the transfer of the asset is expected to qualify for recognition as a completed sale within one year. Real estate assets that are held for sale are carried at the lower of the asset’s carrying amount or its fair value less costs to sell.

Debt Issuance Costs

Debt issuance costs under the Company’s indebtedness are capitalized and amortized over the term of the respective debt instrument. Unamortized debt issuance costs are expensed when the associated debt is repaid prior to maturity. Debt issuance costs related to debt securitizations are capitalized and amortized over the term of the underlying loans using the effective interest method. When an underlying loan is prepaid in a debt securitization and the outstanding principal balance of the securitization debt is reduced, the related unamortized debt issuance costs are charged to expense based on a pro‑rata share

of the debt issuance costs being allocated to the specific loans that were prepaid. Amortization of debt issuance costs is included within interest expense, except as noted below, in the Company’s consolidated statements of operations while the unamortized balance on (i) Secured Funding Agreements (each individually defined in Note 6 included in these consolidated financial statements) is included within other assets and (ii) Notes Payable, the Secured Term Loan (each defined in Note 6 included in these consolidated financial statements) and Secured Borrowings (defined in Note 7 included in these consolidated financial statements) and debt securitizations are each included as a reduction to the carrying amount of the liability, in the Company’s consolidated balance sheets. Amortization of debt issuance costs for the note payable on the hotel property that is recognized as real estate owned in the Company’s consolidated balance sheets (see Note 6 included in these consolidated financial statements for additional information on the note payable) is included within expenses from real estate owned in the Company’s consolidated statements of operations.

The original issue discount (“OID”) on amounts drawn under the Company’s Secured Term Loan represents a discount to the face amount of the drawn debt obligations. The OID is amortized over the term of the Secured Term Loan using the effective interest method and is included within interest expense in the Company’s consolidated statements of operations while the unamortized balance is included as a reduction to the carrying amount of the Secured Term Loan in the Company’s consolidated balance sheets.

Revenue Recognition

Interest income is accrued based on the outstanding principal amount and the contractual terms of each loan. For loans held for investment, the origination fees, contractual exit fees and direct loan origination costs are also recognized in interest income over the initial loan term as a yield adjustment using the effective interest method.

Revenue from real estate owned represents revenue associated with the operations of a hotel property classified as real estate owned. Revenue from the operation of the hotel property is recognized when guestrooms are occupied, services have been rendered or fees have been earned. Revenues are recorded net of any discounts and sales and other taxes collected from customers. Revenues consist of room sales, food and beverage sales and other hotel revenues.

Net Interest Margin and Interest Expense

Net Interest Margin and Interest Expense Net interest margin in the Company’s consolidated statements of operations serves to measure the performance of the Company’s loans as compared to its use of debt leverage. The Company includes interest income from its loans and interest expense related to its Secured Funding Agreements, Notes Payable, securitization debt, the Secured Term Loan (each individually defined in Note 6 included in these consolidated financial statements) and Secured Borrowings (defined in Note 7 included in these consolidated financial statements) in net interest margin.

Income Taxes

The Company has elected and qualified for taxation as a REIT commencing with its taxable year ended December 31, 2012. As a result of the Company’s REIT qualification and its distribution policy, the Company does not generally pay United States federal corporate level income taxes. Many of the REIT requirements, however, are highly technical and complex. To continue to qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a

requirement that the Company distributes annually to its stockholders at least 90% of the Company’s REIT taxable income prior to the deduction for dividends paid. To the extent that the Company distributes less than 100% of its REIT taxable income in any tax year (taking into account any distributions made in a subsequent tax year under Sections 857(b)(9) or 858 of the Code), the Company will pay tax at regular corporate rates on that undistributed portion. Furthermore, if the Company distributes less than the sum of 1) 85% of its ordinary income for the calendar year, 2) 95% of its capital gain net income for the calendar year, and 3) any undistributed shortfall from its prior calendar year (the “Required Distribution”) to its stockholders during any calendar year (including any distributions declared by the last day of the calendar year but paid in the subsequent year), then it is required to pay a non-deductible excise tax equal to 4% of any shortfall between the Required Distribution and the amount that was actually distributed. The 90% distribution requirement does not require the distribution of net capital gains. However, if the Company elects to retain any of its net capital gain for any tax year, it must notify its stockholders and pay tax at regular corporate rates on the retained net capital gain. The stockholders must include their proportionate share of the retained net capital gain in their taxable income for the tax year, and they are deemed to have paid the REIT’s tax on their proportionate share of the retained capital gain. Furthermore, such retained capital gain may be subject to the nondeductible 4% excise tax. If it is determined that the Company’s estimated current year taxable income will be in excess of estimated dividend distributions (including capital gain dividend) for the current year from such income, the Company accrues excise tax on estimated excess taxable income as such taxable income is earned. The annual expense is calculated in accordance with applicable tax regulations. Excise tax expense is included in the line item income tax expense, including excise tax in the consolidated statements of operations included in this annual report on Form 10-K.

The Company formed a wholly-owned subsidiary, ACRC Lender W TRS LLC (“ACRC W TRS”), in December 2013 in order to issue and hold certain loans intended for sale. The Company also formed a wholly-owned subsidiary, ACRC 2017-FL3 TRS LLC (“FL3 TRS”), in March 2017 in order to hold a portion of the CLO Securitization (as defined below), including the portion that generates excess inclusion income. Additionally, the Company also formed a wholly-owned subsidiary, ACRC WM Tenant LLC (“ACRC WM”), in March 2019 in order to lease the hotel property classified as real estate owned, which was acquired on March 8, 2019. Entity classification elections to be taxed as a corporation and taxable REIT subsidiary (“TRS”) elections were made with respect to ACRC W TRS, FL3 TRS and ACRC WM. A TRS is an entity taxed as a corporation that has not elected to be taxed as a REIT, in which a REIT directly or indirectly holds equity, and that has made a joint election with such REIT to be treated as a TRS. A TRS generally may engage in any business, including investing in assets and engaging in activities that could not be held or conducted directly by the Company without jeopardizing its qualification as a REIT. A TRS is subject to applicable United States federal, state and local income tax on its taxable income. In addition, as a REIT, the Company also may be subject to a 100% excise tax on certain transactions between it and its TRS that are not conducted on an arm’s-length basis. For financial reporting purposes, a provision for current and deferred taxes has been established for the portion of the Company’s GAAP consolidated earnings recognized by ACRC W TRS, FL3 TRS and ACRC WM. The income tax provision is included in the line item income tax expense, including excise tax in the consolidated statements of operations included in this annual report on Form 10-K.

FASB ASC Topic 740, Income Taxes (“ASC 740”), prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company has analyzed its various federal and state filing positions and believes that its income tax filing positions and deductions are well documented and supported. As of December 31, 2020 and 2019, based on the Company’s evaluation, there is no reserve for any uncertain income tax positions. ACRC W TRS, FL3 TRS and ACRC WM recognize interest and penalties, if any, related to unrecognized tax benefits within income tax expense in the consolidated statements of operations. Accrued interest and penalties, if any, are included within other liabilities in the consolidated balance sheets.

Comprehensive Income

Comprehensive Income For the years ended December 31, 2020, 2019 and 2018, comprehensive income equaled net income; therefore, a separate consolidated statement of comprehensive income is not included in the accompanying consolidated financial statements.

Share-based Compensation

Stock-Based Compensation

The Company recognizes the cost of stock‑based compensation, which is included within general and administrative expenses in the Company’s consolidated statements of operations. The fair value of the time vested restricted stock or restricted stock units (“RSUs”) granted is recorded to expense on a straight‑line basis over the vesting period for the award, with an offsetting increase in stockholders’ equity. For grants to directors and officers and employees of the Manager, the fair value is determined based upon the market price of the stock on the grant date.

Earnings per Share

Earnings per ShareThe Company calculates basic earnings (loss) per share by dividing net income (loss) allocable to common stockholders for the period by the weighted average shares of common stock outstanding for that period after consideration of the earnings (loss) allocated to the Company’s restricted stock, which are participating securities as defined in GAAP. Diluted earnings (loss) per share takes into effect any dilutive instruments, such as restricted stock, RSUs and convertible debt, except when doing so would be anti‑dilutive.

Recent Accounting Pronouncements

In March 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 optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. ASU No. 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements.
