Description of Business
Description of Business	Note 1 — Description of Business Arbor Realty Trust, Inc. (“we,” “us,” or “our”) is a Maryland corporation formed in 2003. We operate through two business segments: our Structured Loan Origination and Investment Business, or "Structured Business," and our Agency Loan Origination and Servicing Business, or "Agency Business." Through our Structured Business, we invest in a diversified portfolio of structured finance assets in the multifamily, single-family rental and commercial real estate markets, primarily consisting of bridge and mezzanine loans, including junior participating interests in first mortgages, preferred and direct equity. We also invest in real estate-related joint ventures and may also directly acquire real property and invest in real estate-related notes and certain mortgage-related securities. Through our Agency Business, we originate, sell and service a range of multifamily finance products through the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac," and together with Fannie Mae, the government-sponsored enterprises, or "GSEs"), the Government National Mortgage Association ("Ginnie Mae"), Federal Housing Authority ("FHA") and the U.S. Department of Housing and Urban Development (together with Ginnie Mae and FHA, "HUD"). We retain the servicing rights and asset management responsibilities on substantially all loans we originate and sell under the GSE and HUD programs. We are an approved Fannie Mae Delegated Underwriting and Servicing ("DUS") lender nationally, a Freddie Mac Multifamily Conventional Loan lender, seller/servicer, in New York, New Jersey and Connecticut, a Freddie Mac affordable, manufactured housing, senior housing and small balance loan ("SBL") lender, seller/servicer, nationally and a HUD MAP and LEAN senior housing/healthcare lender nationally. We also originate and sell finance products through conduit/commercial mortgage-backed securities ("CMBS") programs and during the third quarter of 2019, we began to originate and service permanent financing loans underwritten using the guidelines of our existing agency loans sold to the GSEs, which we refer to as "Private Label" loans. We pool and securitize the Private Label loans and sell certain securities in the securitizations to third-party investors, while retaining the highest risk bottom tranche certificate. Substantially all of our operations are conducted through our operating partnership, Arbor Realty Limited Partnership ("ARLP"), for which we serve as the general partner, and ARLP's subsidiaries. We are organized to qualify as a real estate investment trust ("REIT") for U.S. federal income tax purposes. A REIT is generally not subject to federal income tax on that portion of its REIT-taxable income that is distributed to its stockholders, provided that at least 90% of taxable income is distributed and provided that certain other requirements are met. Certain of our assets that produce non-qualifying REIT income, primarily within the Agency Business, are operated through taxable REIT subsidiaries ("TRS"), which is part of our TRS consolidated group (the "TRS Consolidated Group") and is subject to U.S. federal, state and local income taxes. In general, our TRS entities may hold assets that the REIT cannot hold directly and may engage in real estate or non-real estate-related business. See Note 17 for details.

Basis of Presentation and Significant Accounting Policies
Basis of Presentation and Significant Accounting Policies	Note 2 — Basis of Presentation and Significant Accounting Policies Basis of Presentation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), for interim financial statements and the instructions to Form 10-Q. Accordingly, certain information and footnote disclosures normally included in the consolidated financial statements prepared under GAAP have been condensed or omitted. In our opinion, all adjustments considered necessary for a fair presentation of our financial position, results of operations and cash flows have been included and are of a normal and recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These financial statements should be read in conjunction with our financial statements and notes thereto included in our 2019 Annual Report. Principles of Consolidation These consolidated financial statements include our financial statements and the financial statements of our wholly owned subsidiaries, partnerships and other joint ventures in which we own a controlling interest, including variable interest entities (“VIEs”) of which we are the primary beneficiary. Entities in which we have a significant influence are accounted for under the equity method. Our VIEs are described in Note 15. All significant inter-company transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that could materially affect the amounts reported in the consolidated financial statements and accompanying notes. During the nine months ended September 30, 2020, there has been a global outbreak of COVID-19, which has forced many countries, including the United States, to declare national emergencies, to institute "stay-at-home" orders, to close financial markets and to restrict operations of non-essential businesses. Such actions are creating significant disruptions in global supply chains, and adversely impacting many industries. COVID-19 has had, and may continue to have, a prolonged adverse impact on economic and market conditions, which could lead to an extended period of global economic slowdown. The impact of COVID-19 on companies is evolving rapidly, and the extent and duration of the economic fallout from this pandemic, both globally and to our business, remain unclear, making any estimate or assumption as of September 30, 2020 inherently less certain than they would be absent the current and potential impacts of COVID-19. Actual results could differ from those estimates. Reclassification Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period financial statements. The net gain/loss from changes in fair value of derivative instruments previously recorded to other income, net is now recorded to loss on derivative instruments, net. These reclassifications had no effect on the previously reported net income. Recently Adopted Accounting Pronouncements Credit Losses On January 1, 2020, we adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which utilizes a current expected credit loss methodology (“CECL”) for the recognition of credit losses for our structured loans and investments, held-to-maturity debt securities and our loss-sharing obligations related to the Fannie Mae DUS program, at the time the financial asset is originated or acquired. The allowance for credit losses is adjusted each period for changes in expected credit losses. This methodology replaces the multiple existing impairment methods in GAAP and generally requires that a loss be incurred before it is recognized. We adopted ASU 2016-13 using the modified retrospective method, therefore, the results for reporting periods prior to January 1, 2020 are unadjusted and reported in accordance with previously applicable GAAP. In connection with the adoption of ASU 2016-13, we recorded a $28.6 million increase to accumulated deficit, which was net of a deferred tax asset of $3.6 million at January 1, 2020. The following table illustrates the impact of adopting January 1, 2020 As Reported Under As Reported Impact of ASU 2016-13 Pre-Adoption Adoption Assets: Allowance for credit losses: Structured loans and investments (1) $ 88,363 $ 71,069 $ 17,294 Held-to-maturity debt securities 501 — 501 Deferred tax assets 27,307 23,713 3,594 Liabilities: Allowance for loss-sharing obligations 16,847 2,441 14,406 (1) See Note 3 for details by asset class. Other Accounting Pronouncements Adopted Description Adoption Date Effect on Financial Statements In November 2018, the Financial Accounting Standards Board ("FASB") issued ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities. This ASU amends the guidance for determining whether a decision-making fee is a variable interest and requires companies to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required under GAAP). First quarter of 2020 The adoption of this guidance did not have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820)—Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with changes between hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. Early adoption is permitted upon issuance of the update. First quarter of 2020 The adoption of this guidance did not have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment. This ASU eliminates step two from the goodwill impairment test, which measures a goodwill impairment loss by comparing the implied fair value with the carrying amount of goodwill. First quarter of 2020 The adoption of this guidance did not have a material impact on our consolidated financial statements. Recently Issued Accounting Pronouncements Description Effective Date Effect on Financial Statements In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40), which includes amendments to the guidance on convertible instruments and the derivative scope exception for contracts in an entity's own equity. The guidance also simplifies the accounting for convertible instruments which include beneficial conversion features or cash conversion features by removing certain separation models in Subtopic 470-20 and requires entities to use the "if-converted" method when calculating diluted earnings per share for convertible instruments. First quarter of 2022, with early adoption permitted beginning in the first quarter of 2021 We are currently evaluating the timing of our adoption and the impact this guidance may have on our consolidated financial statements. In March 2020, the FASB issued ASU 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 that reference LIBOR or other reference rates expected to be discontinued because of reference rate reform. This ASU is effective as of March 12, 2020 through December 31, 2022 We have not adopted any of the optional expedients or exceptions through September 30, 2020 Significant Accounting Policies See Item 8 – Financial Statements and Supplementary Data in our 2019 Annual Report for a description of our significant accounting policies. Upon the adoption of ASU 2016-13 on January 1, 2020, we adjusted certain significant accounting policies, as follows: Allowance for Credit Losses. Our method for calculating the estimate of expected credit loss takes into account historical experience and current conditions for similar loans and reasonable and supportable forecasts about the future. The reasonable and supportable forecast period is determined based on our assessment of the most likely scenario of assumptions and plausible outcomes for the US economy, level of historical loss forecast estimates, material changes in growth and credit strategy and other factors that may affect our loss experience. We regularly evaluate the reasonable and supportable forecast period to determine if a change is needed. Beyond our reasonable and supportable forecast period, we generally revert to historical loss information over the remaining loan/asset period, taken from a period that most accurately reflects the expectation of conditions expected to exist during the period of reversion. We may make adjustments to historical loss information for differences in risk that may not reflect the characteristics of our current portfolio, including but not limited to, loan-to-value and debt service coverage ratios, among other relevant factors. The method of reversion selected represents the best estimate of the collectability of the investments and is reevaluated each reporting period. We generally expect to use an average historical loss for reversion, utilizing an immediate or straight line method for the remaining life of the investments. We also perform a qualitative assessment beyond model estimates, and apply qualitative adjustments as necessary. Our qualitative analysis includes a review of data that may directly impact our estimates including internal and external information about the loan or property including current market conditions, asset specific conditions, property operations or borrower/sponsor details (i.e. refinance, sale, bankruptcy) which allows us to more accurately and reasonably determine the amount of the expected loss for these investments. We also evaluate the contractual life of our assets to determine if changes are needed for contractual extension options, renewals, modifications and prepayments. To the extent possible, we estimate our allowance for credit losses using a pooling approach for homogeneous assets with similar risk characteristics with the goal of enhancing the precision of their estimate. If particular assets no longer display risk characteristics that are similar to those of the pool, we may decide to revise our pools or perform an individual assessment of expected credit losses. If it is determined that a foreclosure is probable, or we expect repayment through the operation or sale of the collateral and the borrower is experiencing financial difficulty, we calculate expected credit losses based on the fair value of the collateral as of the reporting date. During the loan review process, if we determine that it is probable that we will be unable to collect all amounts due for both principal and interest according to the contractual terms of a loan, we consider that loan impaired. We evaluate the capitalization and market discount rates, as well as the borrower's operating income and cash flows, in estimating the value of the underlying collateral when determining if a loan is impaired. We may also obtain a third party appraisal, which may value the collateral through an "as-is" or "stabilized value" methodology. Such appraisals may be used as an additional source of valuation information only and no adjustments are made to appraisals. If upon completion of the valuation, the fair value of the underlying collateral securing the impaired loan is less than the net carrying value of the loan, we record a specific allowance for credit losses with a corresponding charge to the provision for credit losses, and remove the impaired loan from the CECL analysis described above. If the loan modification constitutes a concession whereas we do not receive ample consideration in return for the modification, and the borrower is experiencing financial difficulties and cannot repay the loan under the current terms, then the modification is considered by us to be a troubled debt restructuring. We record interest on modified loans on an accrual basis to the extent the modified loan is contractually current. The allowance for credit losses on a troubled debt restructuring is measured using the same method as all other loans held for investment. Charge-offs to the allowance for credit losses occur when losses are confirmed through the receipt of cash or other consideration from the completion of a sale; when a modification or restructuring takes place in which we grant a concession to a borrower or agree to a discount in full or partial satisfaction of the loan; when we take ownership and control of the underlying collateral in full satisfaction of the loan; when loans are reclassified as other investments; or when significant collection efforts have ceased and it is highly likely that a loss has been realized. Loss on restructured loans is recorded when we have granted a concession to the borrower in the form of principal forgiveness related to the payoff or the substitution or addition of a new debtor for the original borrower or when we incur costs on behalf of the borrower related to the modification, payoff or the substitution or addition of a new debtor for the original borrower. When a loan is restructured, we record our investment at net realizable value, taking into account the cost of all concessions at the date of restructuring. In addition, a gain or loss may be recorded upon the sale of a loan to a third party in the consolidated statements of operations in the period in which the loan was sold.

Certain loans and investments that require an additional rate of interest “Accrual Rate” to be paid at maturity are not included in the weighted average pay rate as shown in the table. (2) The “First Dollar Loan-to-Value (“LTV”) Ratio” is calculated by comparing the total of our senior most dollar and all senior lien positions within the capital stack to the fair value of the underlying collateral to determine the point at which we will absorb a total loss of our position. (3) The “Last Dollar LTV Ratio” is calculated by comparing the total of the carrying value of our loan and all senior lien positions within the capital stack to the fair value of the underlying collateral to determine the point at which we will initially absorb a loss. (4) As of September 30, 2020 and December 31, 2019, bridge loans included 9 and 11, respectively, single-family rental loans with an aggregate UPB of $150.8 million and $66.7 million, respectively, of which $53.7 million and $30.0 million, respectively, was funded. (5) As of September 30, 2020 and December 31, 2019, other included 20 and 12 , respectively, single-family rental permanent loans with an aggregate UPB of $60.8 million and $41.6 million, respectively, and, at December 31, 2019, there were 9 purchased loans with an aggregate UPB of $28.6 million. Concentration of Credit Risk We are subject to concentration risk in that, at September 30, 2020, the UPB related to 22 loans with five different borrowers represented 13% of total assets. At December 31, 2019, the UPB related to 24 loans with five different borrowers represented 13% of total assets. During both the nine months ended September 30, 2020 and the year ended December 31, 2019, no single loan or investment represented more than 10% of our total assets and no single investor group generated over 10% of our revenue. See Note 18 for details on our concentration of related party loans and investments. We assign a credit risk rating of pass, pass/watch, special mention, substandard or doubtful to each loan and investment, with a pass rating being the lowest risk and a doubtful rating being the highest risk. Each credit risk rating has benchmark guidelines that pertain to debt-service coverage ratios, LTV ratios, borrower strength, asset quality, and funded cash reserves. Other factors such as guarantees, market strength, and remaining loan term and borrower equity are also reviewed and factored into determining the credit risk rating assigned to each loan. This metric provides a helpful snapshot of portfolio quality and credit risk. All portfolio assets are subject to, at a minimum, a thorough quarterly financial evaluation in which historical operating performance and forward-looking projections are reviewed, however, we maintain a higher level of scrutiny and focus on loans that we consider “high risk” and that possess deteriorating credit quality. Generally speaking, given our typical loan profile, risk ratings of pass, pass/watch and special mention suggest that we expect the loan to make both principal and interest payments according to the contractual terms of the loan agreement. A risk rating of substandard indicates we anticipate the loan may require a modification of some kind. A risk rating of doubtful indicates we expect the loan to underperform over its term, and there could be loss of interest and/or principal. Further, while the above are the primary guidelines used in determining a certain risk rating, subjective items such as borrower strength, market strength or asset quality may result in a rating that is higher or lower than might be indicated by any risk rating matrix.

Allowance for Credit Losses A summary of the changes in the allowance for credit losses is as follows (in thousands): Three Months Ended September 30, 2020 Land Multifamily Retail Office Hotel Student Housing Healthcare Other Total Allowance for credit losses: Beginning balance $ 78,094 $ 34,606 $ 13,981 $ 8,532 $ 7,672 $ 4,110 $ 3,930 $ 1,886 $ 152,811 Provision for credit losses (net of recoveries) (84) 103 (40) (6,589) (133) 675 (21) 23 (6,066) Ending balance $ 78,010 $ 34,709 $ 13,941 $ 1,943 $ 7,539 $ 4,785 $ 3,909 $ 1,909 $ 146,745 Three Months Ended September 30, 2019 Allowance for credit losses $ 67,869 $ — $ — $ 1,500 $ — $ — $ — $ 1,700 $ 71,069 Nine Months Ended September 30, 2020 Allowance for credit losses: Beginning balance, prior to adoption of CECL $ 67,869 $ — $ — $ 1,500 $ — $ — $ — $ 1,700 $ 71,069 Impact of adopting CECL - January 1, 2020 77 16,322 335 287 29 68 64 112 17,294 Provision for credit losses (net of recoveries) 10,064 18,387 13,606 156 7,510 4,717 3,845 97 58,382 Ending balance $ 78,010 $ 34,709 $ 13,941 $ 1,943 $ 7,539 $ 4,785 $ 3,909 $ 1,909 $ 146,745 Nine Months Ended September 30, 2019 Allowance for credit losses $ 67,869 $ — $ — $ 1,500 $ — $ — $ — $ 1,700 $ 71,069 The decrease in the provision for credit losses during the three months ended September 30, 2020 of $6.1 million was due to improved market conditions and expected future forecasts during the third quarter of 2020. The increase in the provision for credit losses during the nine months ended September 30, 2020 of $58.4 million, compared to the January 1, 2020 cumulative-effect adjustment upon adoption of CECL of $17.3 million, is primarily attributed to the significant adverse change in the economic outlook during the first half of 2020 due to the COVID-19 pandemic. Our estimate of allowance for credit losses on our structured loans and investments, including related unfunded loan commitments, during 2020 was based on a reasonable and supportable forecast period that was adjusted for the expectations that the markets we operate in will experience declines in economic conditions, increases in unemployment rates and other market driven factors largely the result of the COVID-19 pandemic that will likely impact loan delinquencies, modifications and potential risk of loss. For the periods beyond the reasonable and supportable forecast, we reverted to our historical loss rate, which was adjusted to address for factors that are not present in our existing portfolio. We also made adjustments for loans that are expected to extend based on available extension options and the timing of their maturities in relation to current economic conditions. The expected credit losses over the contractual period of our loans also include the obligation to extend credit through our unfunded loan commitments. Our CECL allowance for unfunded loan commitments are adjusted quarterly and correspond with the associated outstanding loans. As of September 30, 2020, we had outstanding unfunded commitments of $194.9 million that we are obligated to fund as borrowers meet certain requirements. As of September 30, 2020, accrued interest receivable related to our loans totaling $38.1 million was excluded from the estimate of credit losses and is included in other assets on the consolidated balance sheet. All of our structured loans and investments are collateral dependent, and as such, the measurement of credit losses may be based on the difference between the fair value of the underlying collateral and the carrying value of the assets as of the period end.

There were no loans for which the fair value of the collateral securing the loan was less than the carrying value of the loan for which we had not recorded a provision for credit loss as of September 30, 2020 and December 31, 2019. At September 30, 2020, eight loans with an aggregate net carrying value of $53.8 million, net of related loan loss reserves of $9.1 million, were classified as non-performing and, at December 31, 2019, three loans with an aggregate net carrying value of $1.8 million, net of related loan loss reserves of $1.7 million, were classified as non-performing. Income from non-performing loans is generally recognized on a cash basis when it is received. Full income recognition will resume when the loan becomes contractually current and performance has recommenced. A summary of our non-performing loans by asset class is as follows (in thousands): September 30, 2020 December 31, 2019 Less Than Greater Than Less Than Greater Than 90 Days 90 Days 90 Days 90 Days UPB Past Due Past Due UPB Past Due Past Due Student Housing $ 36,500 $ — $ 36,500 $ — $ — $ — Multifamily 17,700 — 17,700 — — — Healthcare 4,625 — 4,625 — — — Retail 3,553 — 3,553 1,000 — 1,000 Commercial 1,700 — 1,700 1,700 — 1,700 Office 880 — 880 880 — 880 Total $ 64,958 $ — $ 64,958 $ 3,580 $ — $ 3,580 In addition, we have six loans with a carrying value totaling $120.9 million at September 30, 2020, that are collateralized by a land development project. These loans were scheduled to mature in September 2020 and we are currently in negotiations with the borrower to extend the maturity. The loans do not carry a current pay rate of interest, however, five of the loans with a carrying value totaling $111.5 million entitle us to a weighted average accrual rate of interest of 7.86%. In 2008, we suspended the recording of the accrual rate of interest on these loans, as they were impaired and we deemed the collection of this interest to be doubtful. At September 30, 2020 and December 31, 2019, we had a cumulative allowance for credit losses of $71.4 million and $61.4 million, respectively, related to these loans. The loans are subject to certain risks associated with a development project including, but not limited to, availability of construction financing, increases in projected construction costs, demand for the development's outputs upon completion of the project, and litigation risk. Additionally, these loans were not classified as non-performing as the borrower is in compliance with all of the terms and conditions of the loans. At both September 30, 2020 and December 31, 2019, we had no loans contractually past due 90 days or more that are still accruing interest. During both the three and nine months ended September 30, 2020 and 2019, interest income recognized on nonaccrual loans was de minimis. In the fourth quarter of 2019, we purchased $50.0 million of a $110.0 million bridge loan, which is collateralized by a hotel property and scheduled to mature in December 2022. In the first quarter of 2020, we recorded a $7.5 million allowance for credit losses due to a reduction in the appraisal value of the property. In August 2020, we purchased the remaining $60.0 million bridge loan at a discount for $39.9 million, which we determined had experienced a more than insignificant deterioration in credit quality since origination and, therefore, deemed to be a purchased loan with credit deterioration. The total discount received of $20.1 million was classified as a noncredit discount and no portion of the discount was allocated to allowance for credit losses at the date of purchase since the appraised value of the property is greater than the purchase price. Shortly after the purchase, we entered into a forbearance agreement with the borrower to temporarily reduce the interest rate from LIBOR plus 3.00% with a 1.50% LIBOR floor to a pay rate of 1.00% and to include a $10.0 million principal reduction if the loan is paid-off by March 2, 2021. The temporary reduction in the interest rate is deferred to payoff. In August 2020, we entered into a loan modification agreement on a $26.5 million bridge loan with an interest rate of LIBOR plus 6.00% with a 2.375% LIBOR floor and a $6.1 million mezzanine loan with a fixed rate of 12% collateralized by a retail property to: (1) reduce the interest rate on both loans to the greater of: (i) LIBOR plus 5.50% and (ii) 6.50%, and (2) to extend the maturity date three years to December 2024. A portion of the foregoing interest equal to 2.00% will be deferred to payoff and will be waived if the loan is paid-off by December 31, 2022. The loan modification agreement also includes a $6.0 million required principal paydown, which occurred at the closing of the modification transaction, and an $8.0 million principal reduction once the borrower deposits an additional reserve deposit of approximately $4.6 million by December 31, 2021. We have the ability to potentially recapture up to $8.0 million of the principal reduction to the extent that the property is sold or refinanced in excess of the debt. These two loan modifications were deemed troubled debt restructurings. There were no loan modifications, refinancing's and/or extensions during 2019 that were considered troubled debt restructurings. Given the transitional nature of some of our real estate loans, we may require funds to be placed into an interest reserve, based on contractual requirements, to cover debt service costs. At September 30, 2020 and December 31, 2019, we had total interest reserves of $56.6 million and $37.0 million, respectively, on 152 loans and 131 loans, respectively, with an aggregate UPB of $2.99 billion and $2.43 billion, respectively.

A liability is recognized for the fair value of the guarantee obligation undertaken for the non-contingent aspect of the guarantee and is removed only upon either the expiration or settlement of the guarantee. At September 30, 2020 and 2019, guarantee obligations of $33.2 million and $32.1 million, respectively, were included in the allowance for loss-sharing obligations. In addition to and separately from the fair value of the guarantee, we estimate our allowance for loss-sharing under CECL over the contractual period in which we are exposed to credit risk. The current expected loss related to loss-sharing was based on a collective pooling basis with similar risk characteristics, a reasonable and supportable forecast and a reversion period based on our average historical losses through the remaining contractual term of the portfolio. The increase in the provision for credit losses during the nine months ended September 30, 2020 of $22.5 million, compared to the January 1, 2020 cumulative-effect adjustment upon adoption of CECL of $14.4 million, is primarily attributed to the significant adverse change in the economic outlook due to the COVID-19 pandemic. When we settle a loss under the DUS loss-sharing model, the net loss is charged-off against the previously recorded loss-sharing obligation. The settled loss is often net of any previously advanced principal and interest payments in accordance with the DUS program, which are reflected as reductions to the proceeds needed to settle losses. At September 30, 2020 and December 31, 2019, we had outstanding advances of $0.1 million and $0.5 million, respectively, which were netted against the allowance for loss-sharing obligations. At September 30, 2020, our allowance for loss-sharing obligations, associated with expected losses under CECL was $38.0 million and represented 0.23% of the Fannie Mae servicing portfolio. At September 30, 2020 and December 31, 2019, the maximum quantifiable liability associated with our guarantees under the Fannie Mae DUS agreement was $3.06 billion and $2.73 billion, respectively. The maximum quantifiable liability is not representative of the actual loss we would incur. We would be liable for this amount only if all of the loans we service for Fannie Mae, for which we retain some risk of loss, were to default and all of the collateral underlying these loans was determined to be without value at the time of settlement.

Derivative Financial Instruments	Note 12 — Derivative Financial Instruments We enter into derivative financial instruments to manage exposures that arise from business activities resulting in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. We do not use these derivatives for speculative purposes, but are instead using them to manage our exposure to interest rate risk. Agency Rate Lock and Forward Sale Commitments. We enter into contractual commitments to originate and sell mortgage loans at fixed prices with fixed expiration dates. The commitments become effective when the borrower "rate locks" a specified interest rate within time frames established by us. All potential borrowers are evaluated for creditworthiness prior to the extension of the commitment. Market risk arises if interest rates move adversely between the time of the rate lock by the borrower and the sale date of the loan to an investor. To mitigate the effect of the interest rate risk inherent in providing rate lock commitments to borrowers under the GSE programs, we enter into a forward sale commitment with the investor simultaneously with the rate lock commitment with the borrower. The forward sale contract locks in an interest rate and price for the sale of the loan. The terms of the contract with the investor and the rate lock with the borrower are matched in substantially all respects, with the objective of eliminating interest rate risk to the extent practical. Sale commitments with the investors have an expiration date that is longer than our related commitments to the borrower to allow, among other things, for closing of the loan and processing of paperwork to deliver the loan into the sale commitment. These commitments meet the definition of a derivative and are recorded at fair value, including the effects of interest rate movements which are reflected as a component of other income, net in the consolidated statements of operations. The estimated fair value of rate lock commitments also includes the fair value of the expected net cash flows associated with the servicing of the loan which is recorded as income from MSRs in the consolidated statements of operations. During the three and nine months ended September 30, 2020, we recorded a net loss of $0.9 million and a net gain of $3.3 million, respectively, from changes in the fair value of these derivatives in loss on derivative instruments, net and $42.4 million and $96.7 million, respectively, of income from MSRs. During the three and nine months ended September 30, 2019, we recorded a net loss of $4.7 million and $6.1 million, respectively, from changes in the fair value of these derivatives in loss on derivative instruments, net and $29.9 million and $62.9 million, respectively, of income from MSRs. See Note 13 for details. Interest Rate Swap Futures. During the three months ended September 30, 2020, we recorded realized losses of $0.2 million and unrealized gains of $0.4 million to our Structured Business and realized losses of $0.1 million and unrealized gains of $0.1 million to our Agency Business related to our Swap Futures. During the nine months ended September 30, 2020, we recorded realized losses of $3.0 million and unrealized losses of $0.1 million to our Structured Business and realized losses of $57.3 million and unrealized losses of $1.5 million to our Agency Business related to our Swap Futures. During the three and nine months ended September 30, 2019, we recorded realized losses of $0.4 million and $0.6 million, respectively, and unrealized gains of $0.1 million and unrealized losses of less than $0.1 million, respectively, to our Structured Business related to our Swap Futures. During both the three and nine months ended September 30, 2019, we recorded realized gains of $0.2 million and unrealized losses of $0.2 million to our Agency Business related to our Swap Futures. The realized and unrealized gains and losses are recorded in loss on derivative instruments, net on our consolidated statements of income.

Hierarchical levels directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities are as follows: Level 1—Inputs are unadjusted and quoted prices exist in active markets for identical assets or liabilities, such as government, agency and equity securities. Level 2—Inputs (other than quoted prices included in Level 1) are observable for the asset or liability through correlation with market data. Level 2 inputs may include quoted market prices for a similar asset or liability, interest rates and credit risk. Examples include non-government securities, certain mortgage and asset-backed securities, certain corporate debt and certain derivative instruments. Level 3—Inputs reflect our best estimate of what market participants would use in pricing the asset or liability and are based on significant unobservable inputs that require a considerable amount of judgment and assumptions. Examples include certain mortgage and asset-backed securities, certain corporate debt and certain derivative instruments. Determining which category an asset or liability falls within the hierarchy requires judgment and we evaluate our hierarchy disclosures each quarter. The following is a description of the valuation techniques used to measure fair value and the general classification of these instruments pursuant to the fair value hierarchy. Loans and investments, net. Loans held-for-sale, net. Capitalized mortgage servicing rights, net. Securities held-to-maturity, net. Derivative financial instruments. Credit facilities and repurchase agreements. Collateralized loan obligations, junior subordinated notes and Debt Fund. Senior unsecured notes.

Commitments and Contingencies	Note 14 — Commitments and Contingencies Impact of COVID-19. Agency Business Commitments. As of September 30, 2020, we were required to maintain at least $16.1 million of liquid assets in one of our subsidiaries to meet our operational liquidity requirements for Fannie Mae and we had operational liquidity in excess of this requirement. We are generally required to share the risk of any losses associated with loans sold under the Fannie Mae DUS program and are required to secure this obligation by assigning restricted cash balances and/or a letter of credit to Fannie Mae. The amount of collateral required by Fannie Mae is a formulaic calculation at the loan level by a Fannie Mae assigned tier, which considers the loan balance, risk level of the loan, age of the loan and level of risk-sharing. Fannie Mae requires restricted liquidity for Tier 2 loans of 75 basis points, 15 basis points for Tier 3 loans and 5 basis points for Tier 4 loans, which is funded over a 48-month period that begins upon delivery of the loan to Fannie Mae. A significant portion of our Fannie Mae DUS serviced loans for which we have risk sharing are Tier 2 loans. As of September 30, 2020, we met the restricted liquidity requirement with a $45.0 million letter of credit and $6.9 million of cash collateral. As of September 30, 2020, reserve requirements for the Fannie Mae DUS loan portfolio will require us to fund $39.7 million in additional restricted liquidity over the next 48 months, assuming no further principal paydowns, prepayments, or defaults within our at-risk portfolio. Fannie Mae periodically reassesses these collateral requirements and may make changes to these requirements in the future. We generate sufficient cash flow from our operations to meet these capital standards and do not expect any changes to have a material impact on our future operations; however, future changes to collateral requirements may adversely impact our available cash. We are subject to various capital requirements in connection with seller/servicer agreements that we have entered into with secondary market investors. Failure to maintain minimum capital requirements could result in our inability to originate and service loans for the respective investor and, therefore, could have a direct material effect on our consolidated financial statements. As of September 30, 2020, we met all of Fannie Mae’s quarterly capital requirements and our Fannie Mae adjusted net worth was in excess of the required net worth. We are not subject to capital requirements on a quarterly basis for Ginnie Mae or FHA, as such requirements for these investors are only required on an annual basis. As an approved designated seller/servicer under Freddie Mac's SBL program, we are required to post collateral to ensure that we are able to meet certain purchase and loss obligations required by this program. Under the SBL program, we are required to post collateral equal to $5.0 million, which is satisfied with a $5.0 million letter of credit. We enter into contractual commitments with borrowers providing rate lock commitments while simultaneously entering into forward sale commitments with investors. These commitments are outstanding for short periods of time (generally less than 60 days) and are described in more detail in Note 12 and Note 13. Debt Obligations and Operating Leases.

Unfunded Commitments. Litigation. In June 2011, three related lawsuits were filed by the Extended Stay Litigation Trust (the “Trust”), a post-bankruptcy litigation trust alleged to have standing to pursue claims that previously had been held by Extended Stay, Inc. and the Homestead Village L.L.C. family of companies (together “ESI”) (formerly Chapter 11 debtors, together the "Debtors") that have emerged from bankruptcy. Two of the lawsuits were filed in the U.S. Bankruptcy Court for the Southern District of New York, and the third in the Supreme Court of the State of New York, New York County. There were 73 defendants in the three lawsuits, including 55 corporate and partnership entities and 18 individuals. A subsidiary of ours and certain other entities that are affiliates of ours are included as defendants. The New York State Court action has been removed to the Bankruptcy Court. The lawsuits all allege, as a factual basis and background, certain facts surrounding the June 2007 leveraged buyout of ESI from affiliates of Blackstone Capital. Our subsidiary, Arbor ESH II, LLC, had a $115.0 million investment in the Series A1 Preferred Units of a holding company of Extended Stay, Inc. The New York State Court action and one of the two federal court actions name as defendants Arbor ESH II, LLC, Arbor Commercial Mortgage, LLC ("ACM ") and ABT-ESI LLC, an entity in which we have a membership interest, among the broad group of defendants. These two actions were commenced by substantially identical complaints. The defendants are alleged in these complaints, among other things, to have breached fiduciary and contractual duties by causing or allowing the Debtors to pay illegal dividends or other improper distributions of value at a time when the Debtors were insolvent. These two complaints also allege that the defendants aided and abetted, induced, or participated in breaches of fiduciary duty, waste, and unjust enrichment (“Fiduciary Duty Claims”) and name a director of ours, and a former general counsel of ACM, each of whom had served on the Board of Directors of ESI for a period of time. We are defending these two defendants and paying the costs of such defense. On the basis of the foregoing allegations, the Trust has asserted claims under a number of common law theories, seeking the return of assets transferred by the Debtors prior to the Debtors' bankruptcy filing. In the third action, filed in Bankruptcy Court, the same plaintiff, the Trust, has named ACM and ABT-ESI LLC, together with a number of other defendants and asserts claims, including constructive and fraudulent conveyance claims under state and federal statutes, as well as a claim under the Federal Debt Collection Procedure Act. In June 2013, the Trust filed a motion to amend the lawsuits, to, among other things, (i) consolidate the lawsuits into one lawsuit, (ii) remove 47 defendants, none of whom are related to us, from the lawsuits so that there are 26 remaining defendants, including 16 corporate and partnership entities and 10 individuals, and (iii) reduce the counts within the lawsuits from over 100 down to 17. The remaining counts in the sole remaining amended complaint against our affiliates are principally state law claims for breach of fiduciary duties, waste, unlawful dividends and unjust enrichment, and claims under the Bankruptcy Code for avoidance and recovery actions, among others. The bankruptcy court granted the motion and the amended complaint has been filed. The amended complaint seeks approximately We moved to dismiss the referenced remaining action in December 2013. After supplemental briefing and multiple adjourned conferences, in August 2020, the Court issued a decision granting our motion to dismiss in part, dismissing 9 of the 17 counts. The Court permitted claims against director designees to proceed on theories of authorization of illegal dividends and breach of fiduciary duty. The Court permitted claims against the defendant entities, including our affiliated entities, to proceed on theories of constructive fraudulent transfer and fraudulent transfer under state and federal law. Moreover, the Court affirmatively dismissed four counts against the defendant entities to the extent they are based on distributions from certain so-called LIBOR Floor Certificates. According to the amended complaint, the total LIBOR Floor Certificate transfers were $74.0 million in value. As a result, with what remains of the amended complaint, total possible liability against the affiliated entities has correspondingly fallen, whereas total possible liability against the director designees remains at approximately $139.0 million. The parties have stipulated to a schedule for discovery and we intend to vigorously defend against the remaining claims. We have not made a loss accrual for this litigation because we believe that it is not probable that a loss has been incurred and an amount cannot be reasonably estimated. Due to Borrowers. Due to borrowers represents borrowers’ funds held by us to fund certain expenditures or to be released at our discretion upon the occurrence of certain pre-specified events, and to serve as additional collateral for borrowers’ loans. While retained, these balances earn interest in accordance with the specific loan terms they are associated with.

Variable Interest Entities
Variable Interest Entities	Note 15 — Variable Interest Entities Our involvement with VIEs primarily affects our financial performance and cash flows through amounts recorded in interest income, interest expense, provision for loan losses and through activity associated with our derivative instruments. Consolidated VIEs. Our CLO consolidated entities invest in real estate and real estate-related securities and are financed by the issuance of debt securities. We, or one of our affiliates, are named collateral manager, servicer, and special servicer for all collateral assets held in CLOs, which we believe gives us the power to direct the most significant economic activities of those entities. We also have exposure to losses to the extent of our equity interests and also have rights to waterfall payments in excess of required payments to bond investors. As a result of consolidation, equity interests have been eliminated, and the consolidated balance sheets reflect both the assets held and debt issued to third parties by the CLOs and Debt Fund, prior to the unwind. Our operating results and cash flows include the gross asset and liability amounts related to the CLOs and Debt Fund, prior to the unwind, as opposed to our net economic interests in those entities. The assets and liabilities related to these consolidated CLOs and Debt Fund are as follows (in thousands): September 30, 2020 December 31, 2019 Assets: Restricted cash $ 103,411 $ 208,467 Loans and investments, net 2,993,596 2,557,909 Other assets 15,748 18,380 Total assets $ 3,112,755 $ 2,784,756 Liabilities: Collateralized loan obligations $ 2,516,032 $ 2,130,121 Debt fund — 68,629 Other liabilities 2,713 10,849 Total liabilities $ 2,518,745 $ 2,209,599 Assets held by the CLOs are restricted and can only be used to settle obligations of the CLOs. The liabilities of the CLOs are non-recourse to us and can only be satisfied from each respective asset pool. See Note 10 for details. We are not obligated to provide, have not provided, and do not intend to provide financial support to any of the consolidated CLOs.

The maximum loss exposure as of September 30, 2020 would not exceed the carrying amount of our investment. These unconsolidated VIEs have exposure to real estate debt of approximately $4.88 billion at September 30, 2020.

Income Taxes
Income Taxes	Note 17 — Income Taxes As a REIT, we are generally not subject to U.S. federal income tax to the extent of our distributions to stockholders and as long as certain asset, income, distribution, ownership and administrative tests are met. To maintain our qualification as a REIT, we must annually distribute at least 90% of our REIT-taxable income to our stockholders and meet certain other requirements. We may also be subject to certain state, local and franchise taxes. Under certain circumstances, federal income and excise taxes may be due on our undistributed taxable income. If we were to fail to meet these requirements, we would be subject to U.S. federal income tax, which could have a material adverse impact on our results of operations and amounts available for distributions to our stockholders. We believe that all of the criteria to maintain our REIT qualification have been met for the applicable periods, but there can be no assurance that these criteria will continue to be met in subsequent periods. The Agency Business is operated through our TRS Consolidated Group and is subject to U.S. federal, state and local income taxes. In general, our TRS entities may hold assets that the REIT cannot hold directly and may engage in real estate or non-real estate-related business. In the three and nine months ended September 30, 2020, we recorded a tax provision of $17.8 million and $15.5 million, respectively. In the three and nine months ended September 30, 2019, we recorded a tax provision of $6.6 million and $11.0 million, respectively. The tax provision recorded in the three months ended September 30, 2020 consisted of a current tax provision of $13.9 million and a deferred tax provision of Current and deferred taxes are primarily recorded on the portion of earnings (losses) recognized by us with respect to our interest in the TRS’s. Deferred income tax assets and liabilities are calculated based on temporary differences between our U.S. GAAP consolidated financial statements and the federal, state, local tax basis of assets and liabilities as of the consolidated balance sheets.

Due to related party was $ 0.1 We have a $35.0 million bridge loan and a $7.8 million preferred equity interest on an office building in New York City. The property is controlled by a third party and, beginning in June 2020, its day-to-day operations are managed by an entity owned by an immediate family member of our chief executive officer, which is entitled to an annual fee of $0.3 million and a 33% equity participation interest. In certain instances, our business requires our executives to charter privately owned aircraft in furtherance of our business. In October 2019, we entered into an aircraft time-sharing agreement with an entity controlled by our chief executive officer that owns private aircraft. Pursuant to the agreement, we reimburse the aircraft owner for the required costs under Federal Aviation Administration regulations for the flights our executives' charter. During the nine months ended September 30, 2020, we reimbursed the aircraft owner $0.4 million for the flights chartered by our executives pursuant the agreement. In the first quarter of 2019, we, along with ACM, certain executives of ours and a consortium of independent outside investors, formed AMAC Holdings III LLC ("AMAC III"), a multifamily-focused commercial real estate investment fund sponsored and managed by our chief executive officer and one of his immediate family members. We committed to a $30.0 million investment (of which $10.9 million was funded as of September 30, 2020) for an 18% interest in AMAC III. We recorded a loss of less than $0.1 million and $0.6 million in the three and nine months ended September 30, 2020, respectively, related to this investment. In July 2019, AMAC III originated a $7.0 million mezzanine loan to a borrower with which we have an outstanding $34.0 million bridge loan. In June 2020, for full satisfaction of the mezzanine loan, AMAC III became the owner of the property. In August 2020, the $34.0 million bridge loan was refinanced with a $35.3 million bridge loan, which bears interest at a rate of 350 basis points over LIBOR and matures in August 2022. We also originated a $15.6 million Private Label loan in December 2019 to a borrower which is 100% owned by AMAC III, which bears interest at a fixed rate of 3.735% and matures in January 2030. In May 2020, we sold the Private Label loan to an unconsolidated affiliate of ours. Interest income recorded from our bridge and Private Label loans totaled $1.6 million for the nine months ended September 30, 2020. In 2018, we originated a $61.2 million bridge loan on a multifamily property owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owns 10% of the borrowing entity. The loan has an interest rate of LIBOR plus 4.50% with a LIBOR floor of 2.00% and matures in October 2021. In the fourth quarter of 2019, the related party investors liquidated their equity investment. Interest income recorded from this loan totaled $0.3 million and $1.0 million for the three and nine months ended September 30, 2019, respectively. In 2018, we originated a $37.5 million bridge loan, which was used to purchase several multifamily properties. In January 2019, an entity owned, in part, by an immediate family member of our chief executive officer, purchased a 23.9% interest in the borrowing entity.

In 2018, we originated a $21.7 million bridge loan on a multifamily property owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owns 75% in the borrowing entity. The loan has an interest rate of LIBOR plus 4.75% with a LIBOR floor of 1.25% and matures in June 2021. Interest income recorded from this loan totaled $0.3 million and $1.0 million for the three and nine months ended September 30, 2020, respectively, and $0.4 million and $1.0 million for the three and nine months ended September 30,2019, respectively.

In 2017, we acquired a $32.8 million bridge loan originated by ACM. The loan was used to purchase several multifamily properties by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owned 90% of the borrowing entity. The loan had an interest rate of LIBOR plus 5.0% with a LIBOR floor of 1.13% and was scheduled to mature in June 2020. In October 2019, the borrower repaid this loan in full. Interest income recorded from this loan totaled $0.6 million and $1.9 million for the three and nine months ended September 30, 2019, respectively. In 2017, we originated two bridge loans totaling $28.0 million on two multifamily properties owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owns 45% of the borrowing entity. The loans had an interest rate of LIBOR plus 5.25% with LIBOR floors ranging from 1.24% to 1.54% and were scheduled to mature in the fourth quarter of 2020. The borrower refinanced these loans with a $31.1 million bridge loan we originated in November 2019 with an interest rate of LIBOR plus 4.0%, a LIBOR floor of 1.80% and a maturity date in October 2021. Interest income recorded from these loans totaled $0.5 million and $1.4 million for the three and nine months ended September 30, 2020, respectively, and $0.6 million and $1.7 million for the three and nine months ended September 30, 2019, respectively. In 2017, we originated a $46.9 million Fannie Mae loan on a multifamily property owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers) which owns a 17.6% interest in the borrowing entity. We carry a maximum loss-sharing obligation with Fannie Mae on this loan of up to 5% of the original UPB. Servicing revenue recorded from this loan was less than $0.1 million for all periods presented. In 2017, Ginkgo Investment Company LLC (“Ginkgo”), of which one of our directors is a 33% managing member, purchased a multifamily apartment complex which assumed an existing $8.3 million Fannie Mae loan that we service. Ginkgo subsequently sold the majority of its interest in this property and owned a 3.6% interest at September 30, 2020. We carry a maximum loss-sharing obligation with Fannie Mae on this loan of up to 20% of the original UPB. Upon the sale, we received a 1% loan assumption fee which was governed by existing loan agreements that were in place when the loan was originated in 2015, prior to such purchase. Servicing revenue recorded from this loan was less than $0.1 million for all periods presented. In 2016, we originated $48.0 million of bridge loans on six multifamily properties owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owns interests ranging from 10.5% to 12.0% in the borrowing entities. The loans had an interest rate of LIBOR plus 4.5% with a LIBOR floor of 0.25% and were scheduled to mature in September 2019. In 2017, a $6.8 million loan on one property paid off in full and in 2018 four additional loans totaling $28.3 million paid off in full. In January 2019, $10.9 million of the $12.9 million remaining bridge loan paid off, with the $2.0 million remaining UPB converting to a mezzanine loan with a fixed interest rate of 10.0% and a January 2024 maturity. Interest income recorded from the remaining mezzanine loan totaled $0.1 million and $0.2 million for the three and nine months ended September 30, 2020, respectively, and $0.1 million and $0.2 million for the three and nine months ended September 30, 2019, respectively. In 2016, we originated a $12.7 million bridge loan and a $5.2 million preferred equity investment on two multifamily properties owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owns a 50% interest in the borrowing entity. The bridge loan had an interest rate of LIBOR plus 4.5% with a LIBOR floor of 0.25% and the preferred equity investment had a fixed interest rate of 10%. The bridge loan and the preferred equity investment paid off in full in May 2019. In March 2020, we originated a $14.8 million Private Label loan and a $3.4 million mezzanine loan to the properties. The Private Label loan bears interest at a fixed rate of 3.10% and the mezzanine loan bears interest at a fixed rate of 9.00% and both loans mature in April 2030. In May 2020, we sold the Private Label loan to an unconsolidated affiliate of ours. Interest income recorded from these loans totaled $0.3 million for the nine months ended September 30, 2020 and $0.6 million for the nine months ended September 30, 2019. In 2015, we invested $9.6 million for 50% of ACM's indirect interest in a joint venture with a third party that was formed to invest in a residential mortgage banking business. As a result of this transaction, we had an initial indirect interest of 22.5% in this entity. We recorded income from these investments of $32.3 million and $56.1 million in the three and nine months ended September 30, 2020, respectively, and $2.6 million and $6.1 million in the three and nine months ended September 30, 2019, respectively . In connection with a litigation settlement related to this investment, we provided a guaranty of up to 50% of any amounts payable in connection with the settlement. ACM has also provided us with a guaranty to pay up to 50% of any amounts we may pay under this guaranty. We, along with an executive officer of ours and a consortium of independent outside investors, hold equity investments in a portfolio of multifamily properties referred to as the “Lexford” portfolio, which is managed by an entity owned primarily by a consortium of affiliated investors, including our chief executive officer and an executive officer of ours. Based on the terms of the management contract, the management company is entitled to 4.75% of gross revenues of the underlying properties, along with the potential to share in the proceeds of a sale or restructuring of the debt. In June 2018, the owners of Lexford restructured part of its debt and we originated twelve bridge loans totaling $280.5 million, which were used to repay in full certain existing mortgage debt and to renovate 72 multifamily properties included in the portfolio. The loans were originated in June 2018, had interest rates of LIBOR plus 4.0% and were scheduled to mature in June 2021. During 2019, the borrower made payoffs and partial paydowns of principal totaling $250.0 million. In March 2020, the remaining balance of the loans were refinanced with a $34.6 million Private Label loan, which bears interest at a fixed rate of 3.30% and matures in March 2030. In May 2020, we sold the Private Label loan to an unconsolidated affiliate of ours. Interest income recorded from these loans totaled $0.5 million for the nine months ended September 30, 2020 and $1.1 million and $9.1 million for the three and nine months ended September 30, 2019, respectively. Further, as part of this June 2018 restructuring, $50.0 million in unsecured financing was provided by an unsecured lender to certain parent entities of the property owners. ACM owns slightly less than half of the unsecured lender entity and, therefore, provided slightly less than half of the unsecured lender financing. In addition, in connection with our equity investment, we received distributions totaling $1.1 million during the nine months ended September 30, 2020 and $1.2 million and $0.7 million during the three and nine months ended September 30, 2019, respectively, which were recorded as income from equity affiliates. Separate from the loans we originated in June 2018, we provide limited ("bad boy") guarantees for certain other debt controlled by Lexford. The bad boy guarantees may become a liability for us upon standard "bad" acts such as fraud or a material misrepresentation by Lexford or us. At September 30, 2020, this debt had an aggregate outstanding balance of $613.9 million and is scheduled to mature between 2020 and 2029. Several of our executives, including our chief financial officer, general counsel and our chairman, chief executive officer and president, hold similar positions for ACM. Our chief executive officer and his affiliated entities (“the Kaufman Entities”) together beneficially own approximately 35% of the outstanding membership interests of ACM and certain of our employees and directors also hold an ownership interest in ACM. Furthermore, one of our directors serves as the trustee and co-trustee of two of the Kaufman Entities that hold membership interests in ACM. Upon the closing of the Acquisition in 2016, we issued OP Units, each paired with one share of our special voting preferred shares. At September 30, 2020, ACM holds 3,898,554 shares of our common stock and 11,932,207 OP Units, which represents 11.9% of the voting power of our outstanding stock. Our Board of Directors approved a resolution under our charter allowing our chief executive officer and ACM, (which our chief executive officer has a controlling equity interest in), to own more than the 5% ownership interest limit of our common stock as stated in our amended charter.

Principles of Consolidation	Principles of Consolidation These consolidated financial statements include our financial statements and the financial statements of our wholly owned subsidiaries, partnerships and other joint ventures in which we own a controlling interest, including variable interest entities (“VIEs”) of which we are the primary beneficiary. Entities in which we have a significant influence are accounted for under the equity method. Our VIEs are described in Note 15. All significant inter-company transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that could materially affect the amounts reported in the consolidated financial statements and accompanying notes. During the nine months ended September 30, 2020, there has been a global outbreak of COVID-19, which has forced many countries, including the United States, to declare national emergencies, to institute "stay-at-home" orders, to close financial markets and to restrict operations of non-essential businesses. Such actions are creating significant disruptions in global supply chains, and adversely impacting many industries. COVID-19 has had, and may continue to have, a prolonged adverse impact on economic and market conditions, which could lead to an extended period of global economic slowdown. The impact of COVID-19 on companies is evolving rapidly, and the extent and duration of the economic fallout from this pandemic, both globally and to our business, remain unclear, making any estimate or assumption as of September 30, 2020 inherently less certain than they would be absent the current and potential impacts of COVID-19. Actual results could differ from those estimates.
Reclassification	Reclassification Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period financial statements. The net gain/loss from changes in fair value of derivative instruments previously recorded to other income, net is now recorded to loss on derivative instruments, net. These reclassifications had no effect on the previously reported net income.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Credit Losses On January 1, 2020, we adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which utilizes a current expected credit loss methodology (“CECL”) for the recognition of credit losses for our structured loans and investments, held-to-maturity debt securities and our loss-sharing obligations related to the Fannie Mae DUS program, at the time the financial asset is originated or acquired. The allowance for credit losses is adjusted each period for changes in expected credit losses. This methodology replaces the multiple existing impairment methods in GAAP and generally requires that a loss be incurred before it is recognized. We adopted ASU 2016-13 using the modified retrospective method, therefore, the results for reporting periods prior to January 1, 2020 are unadjusted and reported in accordance with previously applicable GAAP. In connection with the adoption of ASU 2016-13, we recorded a $28.6 million increase to accumulated deficit, which was net of a deferred tax asset of $3.6 million at January 1, 2020. The following table illustrates the impact of adopting January 1, 2020 As Reported Under As Reported Impact of ASU 2016-13 Pre-Adoption Adoption Assets: Allowance for credit losses: Structured loans and investments (1) $ 88,363 $ 71,069 $ 17,294 Held-to-maturity debt securities 501 — 501 Deferred tax assets 27,307 23,713 3,594 Liabilities: Allowance for loss-sharing obligations 16,847 2,441 14,406 (1) See Note 3 for details by asset class. Other Accounting Pronouncements Adopted Description Adoption Date Effect on Financial Statements In November 2018, the Financial Accounting Standards Board ("FASB") issued ASU 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities. This ASU amends the guidance for determining whether a decision-making fee is a variable interest and requires companies to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required under GAAP). First quarter of 2020 The adoption of this guidance did not have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820)—Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with changes between hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. Early adoption is permitted upon issuance of the update. First quarter of 2020 The adoption of this guidance did not have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment. This ASU eliminates step two from the goodwill impairment test, which measures a goodwill impairment loss by comparing the implied fair value with the carrying amount of goodwill. First quarter of 2020 The adoption of this guidance did not have a material impact on our consolidated financial statements. Recently Issued Accounting Pronouncements Description Effective Date Effect on Financial Statements In August 2020, the FASB issued ASU 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity's Own Equity (Subtopic 815-40), which includes amendments to the guidance on convertible instruments and the derivative scope exception for contracts in an entity's own equity. The guidance also simplifies the accounting for convertible instruments which include beneficial conversion features or cash conversion features by removing certain separation models in Subtopic 470-20 and requires entities to use the "if-converted" method when calculating diluted earnings per share for convertible instruments. First quarter of 2022, with early adoption permitted beginning in the first quarter of 2021 We are currently evaluating the timing of our adoption and the impact this guidance may have on our consolidated financial statements. In March 2020, the FASB issued ASU 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 that reference LIBOR or other reference rates expected to be discontinued because of reference rate reform. This ASU is effective as of March 12, 2020 through December 31, 2022 We have not adopted any of the optional expedients or exceptions through September 30, 2020 Significant Accounting Policies See Item 8 – Financial Statements and Supplementary Data in our 2019 Annual Report for a description of our significant accounting policies. Upon the adoption of ASU 2016-13 on January 1, 2020, we adjusted certain significant accounting policies, as follows: Allowance for Credit Losses. Our method for calculating the estimate of expected credit loss takes into account historical experience and current conditions for similar loans and reasonable and supportable forecasts about the future. The reasonable and supportable forecast period is determined based on our assessment of the most likely scenario of assumptions and plausible outcomes for the US economy, level of historical loss forecast estimates, material changes in growth and credit strategy and other factors that may affect our loss experience. We regularly evaluate the reasonable and supportable forecast period to determine if a change is needed. Beyond our reasonable and supportable forecast period, we generally revert to historical loss information over the remaining loan/asset period, taken from a period that most accurately reflects the expectation of conditions expected to exist during the period of reversion. We may make adjustments to historical loss information for differences in risk that may not reflect the characteristics of our current portfolio, including but not limited to, loan-to-value and debt service coverage ratios, among other relevant factors. The method of reversion selected represents the best estimate of the collectability of the investments and is reevaluated each reporting period. We generally expect to use an average historical loss for reversion, utilizing an immediate or straight line method for the remaining life of the investments. We also perform a qualitative assessment beyond model estimates, and apply qualitative adjustments as necessary. Our qualitative analysis includes a review of data that may directly impact our estimates including internal and external information about the loan or property including current market conditions, asset specific conditions, property operations or borrower/sponsor details (i.e. refinance, sale, bankruptcy) which allows us to more accurately and reasonably determine the amount of the expected loss for these investments. We also evaluate the contractual life of our assets to determine if changes are needed for contractual extension options, renewals, modifications and prepayments. To the extent possible, we estimate our allowance for credit losses using a pooling approach for homogeneous assets with similar risk characteristics with the goal of enhancing the precision of their estimate. If particular assets no longer display risk characteristics that are similar to those of the pool, we may decide to revise our pools or perform an individual assessment of expected credit losses. If it is determined that a foreclosure is probable, or we expect repayment through the operation or sale of the collateral and the borrower is experiencing financial difficulty, we calculate expected credit losses based on the fair value of the collateral as of the reporting date. During the loan review process, if we determine that it is probable that we will be unable to collect all amounts due for both principal and interest according to the contractual terms of a loan, we consider that loan impaired. We evaluate the capitalization and market discount rates, as well as the borrower's operating income and cash flows, in estimating the value of the underlying collateral when determining if a loan is impaired. We may also obtain a third party appraisal, which may value the collateral through an "as-is" or "stabilized value" methodology. Such appraisals may be used as an additional source of valuation information only and no adjustments are made to appraisals. If upon completion of the valuation, the fair value of the underlying collateral securing the impaired loan is less than the net carrying value of the loan, we record a specific allowance for credit losses with a corresponding charge to the provision for credit losses, and remove the impaired loan from the CECL analysis described above. If the loan modification constitutes a concession whereas we do not receive ample consideration in return for the modification, and the borrower is experiencing financial difficulties and cannot repay the loan under the current terms, then the modification is considered by us to be a troubled debt restructuring. We record interest on modified loans on an accrual basis to the extent the modified loan is contractually current. The allowance for credit losses on a troubled debt restructuring is measured using the same method as all other loans held for investment. Charge-offs to the allowance for credit losses occur when losses are confirmed through the receipt of cash or other consideration from the completion of a sale; when a modification or restructuring takes place in which we grant a concession to a borrower or agree to a discount in full or partial satisfaction of the loan; when we take ownership and control of the underlying collateral in full satisfaction of the loan; when loans are reclassified as other investments; or when significant collection efforts have ceased and it is highly likely that a loss has been realized. Loss on restructured loans is recorded when we have granted a concession to the borrower in the form of principal forgiveness related to the payoff or the substitution or addition of a new debtor for the original borrower or when we incur costs on behalf of the borrower related to the modification, payoff or the substitution or addition of a new debtor for the original borrower. When a loan is restructured, we record our investment at net realizable value, taking into account the cost of all concessions at the date of restructuring. In addition, a gain or loss may be recorded upon the sale of a loan to a third party in the consolidated statements of operations in the period in which the loan was sold.

Schedule of company's CLO compliance tests as of the most recent determination dates	Our CLO compliance tests as of the most recent determination dates in October 2020 are as follows: Cash Flow Triggers CLO IX CLO X CLO XI CLO XII CLO XIII Overcollateralization (1) Current 134.68 % 126.98 % 121.95 % 118.87 % 119.76 % Limit 133.68 % 125.98 % 120.95 % 117.87 % 118.76 % Pass / Fail Pass Pass Pass Pass Pass Interest Coverage (2) Current 522.55 % 445.37 % 403.28 % 377.12 % 371.60 % Limit 120.00 % 120.00 % 120.00 % 120.00 % 120.00 % Pass / Fail Pass Pass Pass Pass Pass (1) The overcollateralization ratio divides the total principal balance of all collateral in the CLO by the total principal balance of the bonds associated with the applicable ratio. To the extent an asset is considered a defaulted security, the asset’s principal balance for purposes of the overcollateralization test is the lesser of the asset’s market value or the principal balance of the defaulted asset multiplied by the asset’s recovery rate which is determined by the rating agencies. Rating downgrades of CLO collateral will generally not have a direct impact on the principal balance of a CLO asset for purposes of calculating the CLO overcollateralization test unless the rating downgrade is below a significantly low threshold (e.g. CCC-) as defined in each CLO vehicle. (2) The interest coverage ratio divides interest income by interest expense for the classes senior to those retained by us.
