The consolidated financial statements include the accounts of the Predecessor, prior to the Business Combination, which was determined to be FoA Equity, a limited liability company that was formed in July 2020. Prior to the Business Combination, FoA Equity was a wholly owned subsidiary of UFG. FoA Equity owned all of the outstanding equity interests or had a controlling financial interest in FOAF. FAH and Incenter LLC were wholly owned subsidiaries of FOAF, and are included in the consolidated financial statements along with their consolidated operating lending subsidiaries and operating service subsidiaries. See Note 1—Organization and Description of Business for additional information. The significant accounting policies described below, together with the other notes that follow, are an integral part of the consolidated financial statements. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates and assumptions due to factors such as changes in the economy, interest rates, secondary market pricing, prepayment assumptions, home prices or discrete events affecting specific borrowers, and such differences could be material. Principles of Consolidation The consolidated financial statements include the accounts of the Company, its controlled subsidiaries and certain variable interest entities (“VIEs”) where the Company is the primary beneficiary. The Company is deemed to be the primary beneficiary of a VIE when it has both (1) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and (2) exposure to benefits and/or losses that could potentially be significant to the entity. Assets and liabilities of VIEs and their respective results of operations are consolidated from the date that the Company became the primary beneficiary through the date that the Company ceases to be the primary beneficiary. FoA Equity consolidates the accounts of Finance of America Commercial Holdings LLC (“FACo Holdings”), which is a direct subsidiary of FAH and an indirect parent company of FACo. Through the date of the Business Combination, the noncontrolling interests of FACo Holdings met the definition of contingently redeemable financial instruments for which the ability to redeem was outside the control of the consolidating entity. The Con Business Combinations The Company applies the acquisition method to all transactions and other events in which the entity obtains control over one or more other businesses. Assets acquired and liabilities assumed are measured at fair value as of the acquisition date. Liabilities related to contingent consideration are recognized at the acquisition date and re-measured Under ASC 805, there is an option to apply push-down accounting, which establishes a new basis for the assets and liabilities of the acquired company based on a “push-down” of the acquirer’s stepped-up VIEs The Company has been the transferor in connection with securitizations or asset-backed financing arrangements with special purpose entities (“SPE”), in which the Company has continuing involvement with the underlying transferred financial assets. The Company’s continuing involvement includes acting as servicer for the mortgage loans transferred and retaining beneficial interests in the SPE to which the assets were transferred. The Company evaluates its interests in each SPE for classification as a VIE in accordance with ASC 810-10 Consolidation The beneficial interests held consist of residual securities that were retained at the time of securitization. These beneficial interests may obligate the Company to absorb losses of the VIE that could potentially be significant to the VIE, or affords the Company the right to receive benefits from the VIE that could potentially be significant. In addition, when the Company acts as servicer of the transferred assets, the Company retains the power to direct the activities of the VIE that most significantly impact the economic performance of the VIE. When it is determined that the Company has both the power to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE, the assets and liabilities of these VIEs are included in the consolidated financial statements of the Company. The Company reassesses its evaluation of an entity as a VIE upon the occurrence of certain reconsideration events as the primary beneficiary determination may change over time as interest in the VIE changes. The Company elected the fair value option provided for by ASC 825-10, Financial Instruments-Overall See Note 3—Variable Interest Entities and Securitizations for further discussion of VIEs in which the Company is deemed to be the primary beneficiary. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. These investments are with high quality financial, governmental or corporate institutions and potentially subject the Company to concentrations of credit risk. December 31, December 31, Successor Predecessor Cash and cash equivalents $ 141,238 $ 233,101 Restricted cash 322,403 306,262 Total cash, cash equivalents, and restricted cash in statement of cash flows $ 463,641 $ 539,363 Restricted Cash Restricted cash includes amounts specifically designated to repay debt and provide over-collateralization within warehouse facilities and securitized nonrecourse debt obligations, custodial accounts related to the Company’s portfolio of mortgage loans serviced for investors, and funds deposited from prospective borrowers to cover out-of-pocket Loans Held for Investment, Subject to HMBS Related Obligations, at Fair Value The Company elected the fair value option provided for by ASC 825-10, Financial Instruments-Overall A maturity event will cause the loan to become due and payable. Maturity events include: borrower has passed away and the property is not the principal residence of at least one surviving borrower; borrower has sold or conveyed title of the property to a third party; the property is no longer the principal residence of at least one borrower for reasons other than death; the borrower does not maintain the property as principal residence for a period exceeding 12 months; the borrower fails to pay property taxes and/or insurance and all attempts to rectify the situation have been exhausted; and the property is in disrepair and the borrower has refused or is unable to repair the property. Once a loan has become due and payable, unsecuritized borrower advances cannot be placed into a Ginnie Mae HMBS. Generally, the Company recovers such advances (referred to as unpoolable tails) from borrowers, from proceeds of liquidation of collateral or ultimate disposition of the loan, including conveyance of claims to FHA. If the loan is not paid within six months of the maturity event, the Company may proceed with foreclosure on the property. A loan may be satisfied by borrower repayment, sales or appraisal-based claim submissions to HUD and/or foreclosure sale proceeds. If the Company sells the property within six months, it may file a sales-based claim with HUD to recover any shortfall between the sales price of the property and the outstanding loan balance. If the property is not sold within six months, the Company may file an appraisal-based claim with HUD to recover any shortfall between the appraised value and the outstanding loan balance. Once the appraisal based claim is paid by HUD, any subsequent expenses or loss in the property’s value exposes the Company to additional losses that may not be eligible to be recouped through the filing of an additional HUD claim. The Company has determined that HECM loans transferred under the current Ginnie Mae HMBS securitization program do not meet the requirements for sale accounting and are not derecognized upon date of transfer. The Ginnie Mae HMBS securitization program includes certain terms that do not meet the participating interest requirements and require or provide an option for the Company to reacquire the loans prior to maturity. Due to these terms, the transfer of the loans does not meet the requirements of sale accounting. As a result, the Company accounts for HECM loans transferred into HMBS securitizations as secured borrowings and continues to recognize the loans as held for investment, subject to HMBS related obligations, along with the corresponding liability for the HMBS related obligations. No gains or losses are recognized on these transfers of HECM loans into HMBS securitizations. Loans are considered nonperforming upon events such as, but not limited to, the death of the mortgagor, the mortgagor no longer occupying the property as their principal residence, or the property taxes or insurance not being paid. In addition to having to fund these repurchases, the Company also typically earns a lower interest rate and incurs certain non-reimbursable Loans held for investment, subject to HMBS related obligations, also include claims receivable that have been submitted to HUD awaiting reimbursement. These amounts are recorded net of amounts the Company does not expect to recover through outstanding claims. The yield recognized on loans held for investment, subject to HMBS related obligations, and changes in estimated fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The yield recognized includes the recognition of interest income based on the stated interest rates of the loans that is expected to be collected through conveyance of loans to FHA, repayment by borrower or through disposition of real estate upon foreclosure. Loan origination fees represent an up-front Certain HECM and jumbo reverse mortgage loans originated or acquired by the Company include broker compensation or correspondent fees. These premiums are remitted to the mortgage broker or correspondent lender who acted as the intermediary for the reverse mortgage. Broker compensation and correspondent fees are recorded on a net basis in net fair value gains on loans and related obligations in the Consolidated Statements of Operations and therefore not separately presented. See Note 5—Fair Value for further discussion of valuation of loans held for investment, subject to HMBS related obligations. Loans Held for Investment, Subject to Nonrecourse Debt, at Fair Value Loans held for investment, subject to nonrecourse debt, at fair value, are loans that were securitized and serve as collateral for the issued nonrecourse debt, including HECM Buyouts, agricultural securitized loans, fix & flip securitized loans, and non FHA-insured (“non-agency The yield recognized on loans held for investment, subject to nonrecourse debt, at fair value and changes in estimated fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The yield recognized includes the contractual interest income that is expected to be collected based on the stated interest rates of the loans. Loans Held for Investment, at Fair Value Loans held for investment, at fair value, consists of certain reverse mortgage and commercial mortgage loans that the Company intends to hold to maturity. The Company has elected the fair value option for all loans held for investment and determines the fair value, on a recurring basis, based on DCF models. These valuations require the use of judgment by the Company and changes in assumptions can have a significant impact on the determination of the loan’s fair value. The difference between the cost basis of newly originated or acquired loans and their estimated fair value is recognized in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. See Note 5—Fair Value for further discussion of valuation of loans held for investment. The yield recognized on loans held for investment and changes in estimated fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The yield recognized includes the contractual interest income that is expected to be collected based on the stated interest rates of the loans. Reverse Mortgage Loans Reverse mortgage loans held for investment consists of originated or purchased HECM and non-agency HECM loans and tails that have not yet been securitized into HMBS consist primarily of newly-issued HECMs that the Company has either originated or purchased, subsequent borrower draws and amounts paid by the Company on the borrower’s behalf for MIP that have not yet been transferred to a Ginnie Mae securitization. As a jumbo reverse mortgage, non-agency Non-agency The Company, as an issuer of HMBS, is required to repurchase reverse loans out of the Ginnie Mae securitization pools once the outstanding principal balance of the related HECM is equal to or greater than 98% of the Maximum Claim Amount (“MCA”) (referred to as HECM Buyouts). Performing repurchased loans are conveyed to HUD and payment is received from HUD typically within 75 days of repurchase. Nonperforming repurchased loans are generally liquidated through foreclosure, subsequent sale of the real estate owned, and claim submissions to HUD. Loans are considered nonperforming upon events such as, but not limited to, the death of the mortgagor, the mortgagor no longer occupying the property as their principal residence, or the property taxes or insurance not being paid. In addition to having to fund these repurchases, the Company also typically earns a lower interest rate and incurs certain non-reimbursable Reverse mortgage loans also include claims receivable that have been submitted to HUD awaiting reimbursement. These amounts are recorded net of amounts the Company does not expect to recover through outstanding claims. Certain HECM and jumbo reverse mortgage loans originated or acquired by the Company include broker compensation or correspondent fees. These premiums are remitted to the mortgage broker or correspondent lender who acted as the intermediary for the reverse mortgage. Broker compensation and correspondent fees are recorded on a net basis in net fair value gains on loans and related obligations and therefore are not separately presented in the Consolidated Statements of Operations. Commercial Mortgage Loans Commercial mortgage loans held for investment primarily consist of short-term loans for real estate investors and agricultural loans for farmers. Loans Held for Sale, at Fair Value Loans held for sale, at fair value, represent mortgage loans originated by the Company and held until sold to secondary market investors. The Company primarily originates conventional GSEs, government insured (FHA), and government guaranteed (Department of Veteran Affairs) residential mortgage loans (collectively “residential mortgage loans held for sale”), and commercial mortgage loans to owners and investors of single and multi-family residential rental properties (“commercial loans held for sale”). The Company elected the fair value option provided for by ASC 825-10, Financial Instruments-Overall Loans held for sale are measured at fair value at the time of origination and on a recurring basis thereafter. Gains and losses on loans held for sale are recorded in gain on sale and other income from loans held for sale, net, in the Consolidated Statements of Operations. The yield recognized includes the contractual interest income that is expected to be collected based on the stated interest rates of the loans. In connection with the Company’s election to measure originated loans held for sale at fair value, any fees recognized in relation to originated loans are recognized as they are received and are included in fee income in the Consolidated Statements of Operations. Direct loan origination costs and fees are expensed when incurred and are included in general and administrative expenses in the Consolidated Statements of Operations. Residential Mortgage and Home Improvement Loans Held for Sale Residential mortgage and home improvement loans held for sale are typically warehoused for a period after origination or purchase before sale into the secondary market. Servicing rights are either released upon sale of mortgage loans in the secondary market or retained by the Company. The yield on residential mortgage loans held for sale is recorded in interest income and changes in fair value are recorded in gain on sale and other income from loans held for sale, net, in the Consolidated Statements of Operations. Commercial Loans Held for Sale The Company estimates fair value by evaluating a variety of market indicators, including recent sales of similar product types and outstanding commitments, calculated on an aggregate basis. The yield recognized on commercial loans held for sale and changes in estimated fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. In connection with the Company’s election to measure loans held for sale at fair value, the Company is not permitted to defer the loan origination fees, net of direct loan origination costs associated with these loans. Mortgage Servicing Rights, at Fair Value Mortgage servicing rights (“MSRs”) represent contractual rights to perform specific administrative functions for the underlying loans including specified mortgage servicing activities, which consist of collecting loan payments, remitting principal and interest payments to investors, managing escrow funds for the payment of mortgage-related expenses such as taxes and insurance, and otherwise administrating the mortgage loan servicing portfolio. MSRs are created through the sale of an originated mortgage loan or purchased from third parties. The unpaid principal balance (“UPB”) of the loans underlying the MSRs is not included i The Company follows the fair value measurement method to record the value of MSRs in accordance with ASC 860, Transfers and Servicing The fair value of the MSRs is based upon the present value of the expected future net cash flows related to servicing these loans. For MSRs that the Company has current commitments to sell to third parties, the fair value is based on the outstanding commitment price. The Company receives a base servicing fee based on the remaining outstanding principal balances of the loans, which are collected from borrowers on a monthly basis. The Company determines the fair value of the MSRs by the use of a DCF model that incorporates prepayment speeds, delinquencies, discount rate, ancillary revenues and other assumptions (including costs to service) that management believes are consistent with the assumptions other similar market participants use in valuing the MSRs. The primary risk associated with MSRs is the potential reduction in fair value as a result of higher than anticipated prepayments due to loan refinancing prompted, in part, by declining interest rates or government intervention. Conversely, these assets generally increase in value in a rising interest rate environment to the extent that prepayments are slower than anticipated. At times, the Company may utilize derivatives as economic hedges to offset changes in the fair value of the MSRs resulting from the actual or anticipated changes in prepayments stemming from changing interest rate environments. There is also a risk of valuation decline due to higher than expected increases in default rates, which the Company does not believe can be effectively managed using derivatives. Debt Securities Debt securities consists of U.S. government securities, securities backed by collateral pools of non-agency reverse mortgages that are not insured by the FHA, and other debt securities. The Company accounts for debt securities in accordance with ASC 320 , Investments-Debt and Equity Securities (“ASC 320 ”). The Company determines the classification of securities at purchase. The Company classifies debt securities into held-to-maturity, trading, or available-for-sale categories. Debt securities that management has the ability and intent to hold to maturity are classified as held-to-maturity and carried at amortized cost adjusted for amortization of premiums and accretion of discounts amortized over the contractual term of the securities in a method that approximates the interest method. The Company has elected to account for certain debt securities at fair value under the fair value option provisions included in ASC 825, Financial Instruments instrument-by-instrument Derivatives and Hedging Activities The Company’s principal market exposure is to interest rate risk, specifically long-term U.S. Treasury and mortgage interest rates due to their impact on the fair value of mortgage loans and related commitments. The Company uses derivative instruments as part of its overall strategy to manage its exposure to market and price risks primarily associated with fluctuations in interest rates. As a matter of policy, the Company does not use derivatives for speculative purposes. Interest Rate Lock Commitments Interest rate lock commitments (“IRLCs”) represent an agreement to extend credit to a mortgage loan applicant, whereby the interest rate on the loan is set prior to funding. The IRLC binds the Company (subject to the loan approval process) to lend funds to a potential borrower at the specified rate, regardless of whether interest rates have changed between the commitment date and the loan funding date. As such, outstanding IRLCs are subject to interest rate risk and related price risk during the period from the date of issuance through the date of loan funding, cancellation or expiration. The Company uses mandatory and best efforts commitments to substantially mitigate these risks. Loan commitments generally range between 30 and 90 days; however, the borrower is not obligated to obtain the loan. The Company is subject to fallout risk related to IRLCs, which is realized if approved borrowers choose not to close on the loans within the terms of the IRLCs. Historical commitment-to-closing IRLCs that relate to the origination of a mortgage that will be held for sale upon funding are considered derivative instruments under the derivatives and hedging accounting guidance ASC 815, Derivatives and Hedging The fair value of the Company’s IRLCs is based upon the estimated fair value of the underlying mortgage loan, adjusted for (i) estimated costs to complete and originate the loan and (ii) the estimated percentage of IRLCs that will result in a closed mortgage loan. The valuation of the Company’s IRLCs are based on prices of MBS in the market place and the value of the related mortgage servicing. Forward Loan Sale Commitments The Company is subject to interest rate and price risk on its loans held for sale, at fair value, and IRLCs from the date the IRLC is made until the date the loan is sold. Mandatory commitments which fix the forward sales price that will be realized in the secondary market are used to substantially mitigate the interest rate and price risk to the Company. The Company carefully evaluates all loan sale agreements to determine whether they meet the definition of a derivative under the derivatives and hedging accounting guidance under ASC 815. To mitigate the price risk the Company is exposed to on its outstanding loan commitments, the Company uses “mandatory delivery” forward loan sale commitments to manage the risk of potential interest rate movements and their impact on the value of the underlying mortgage loans. Mandatory delivery contracts that meet the definition of a derivative are accounted for as derivative instruments. Accordingly, forward loan sale commitments are recognized at fair value on the Consolidated Statements of Financial Condition in derivative assets or payables and other liabilities with changes in their fair values recorded in gain on sale and other income from loans held for sale, net, in the Consolidated Statements of Operations. The fair value is determined on a recurring basis based on forward prices with dealers in such securities or internally-developed or third party models utilizing observable market inputs. To Be Announced Securities To Be Announced Securities (“TBAs”) are “forward delivery” securities considered derivative instruments under derivatives and hedging accounting guidance ASC 815. The Company uses TBAs to protect against the price risk inherent in derivative loan commitments. TBAs are valued based on forward dealer marks from the Company’s approved counterparties. The Company utilizes internal and third party market pricing services which compile current prices for instruments from market sources, and those prices represent the current executable price. TBAs are recorded at fair value in the Consolidated Statements of Financial Condition in derivative assets and payables and other liabilities, with changes in fair value recorded in gain on sale and other income from loans held for sale, net, and net fair value gains on loans and related obligations in the Consolidated Statements of Operations. Best Efforts Commitments The Company uses best efforts commitments with various investors to mitigate the risk associated with loans held for sale, at fair value , Forward MBS Commitments Periodically, the Company uses forward MBS commitments to hedge changes in the value of MSRs. MSRs are subject to substantial interest rate risk as the mortgage loans underlying the servicing rights permit the borrowers to prepay the loans. The Company may at times enter into economic hedges, which do not qualify as hedges for accounting purposes, including forward contracts to minimize the effects of loss in value of these MSRs associated with increased prepayment activity that generally results from declining interest rates. Forward MBS commitments are recorded at fair value in the Consolidated Statements of Financial Condition in derivative assets and payables and other liabilities, with changes in fair value recorded in gain on sale and other income from loans held for sale, net, in the Consolidated Statements of Operations. The Company treats forward HMBS purchase and sale commitments that have not settled as derivative instruments. Any changes in fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The fair value is determined on a recurring basis based on forward prices with dealers in such securities or internally-developed or third party models utilizing observable market inputs. These forward commitments will be fulfilled with loans not yet securitized and new reverse mortgage loan originations and purchases. Interest Rate Swaps, Interest Rate Swap Futures and Futures Contracts The Company also enters into interest rate swaps, interest rate swap futures and futures contracts to offset changes in the value of its non-agency Fixed Assets and Leasehold Improvements, Net Fixed assets are depreciated on a straight-line basis over their estimated useful lives. Leasehold improvements are amortized on a straight-line basis over the shorter of the term of the related office lease or the expected useful life of the assets. The Company capitalizes certain costs associated with the acquisition of internal-use Goodwill Goodwill is the excess of the purchase price over the fair value of the net assets acquired. Goodwill is not amortized, but is reviewed for impairment annually as of October 1 and monitored for interim triggering events on an ongoing basis. If triggering events occur, which indicate goodwill might be impaired between annual tests, goodwill will be tested when such events occur. In making this assessment, the Company considers a number of factors including, but not limited to, operating results, business plans, economic projections, share price and anticipated future cash flows. There are inherent uncertainties related to these factors and management’s judgment in applying them to the analysis of goodwill impairment. Changes in economic and operating conditions could result in goodwill impairment in future periods. In testing goodwill for impairment, the Company performs a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit is less than its carrying value including goodwill. If the qualitative assessment determines that it is more likely than not that the fair value of the reporting unit is less than its carrying value including goodwill, the Company will compare the fair value of that reporting unit with its carrying value including goodwill. If the carrying value of a reporting unit exceeds its fair value, goodwill is considered impaired with the impairment loss equal to the amount by which the carrying value of the goodwill exceeds the implied fair value of that goodwill. Impairment related to goodwill is recorded in impairment of goodwill and intangible assets on the Consolidated Statements of Operations. Intangible Assets, Net Intangible assets, net, primarily consist of trade names and broker/customer relationships acquired through various acquisitions and the Business Combination and recorded at their estimated fair value on the date of Leases The Company evaluates all leases at inception under ASC 842 and classifies the lease as either an operating or a finance lease. The Company currently only has operating leases. Operating lease ROU assets represent the Company’s right to use an underlying asset during the lease term. ROU assets are further adjusted for lease incentives. Operating lease expense is recognized on a straight-line basis over the lease term and is recorded in general and administrative expenses in the Consolidated Statements of Operations. The Company recognizes variable lease payments associated with the Company’s leases when the variability is resolved. Variable lease payments are recorded in Occupancy, equipment rentals and other office related expenses in the Consolidated Statements of Operations along with expenses arising from fixed lease payments. See Note 21 - Leases for more information. Operating lease liabilities represent the Company’s obligation to make lease payments arising from the terms of the lease. The lease liabilities are initially recognized based on the present value of the remaining lease payments using a discount rate that represents the Company’s incremental borrowing rate as of the lease commencement date. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate bas

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities and Securitizations	3. Variable Interest Entities and Securitizations The Company determined that the SPEs created in connection with its securitizations are VIEs. A VIE is an entity that has either a total equity investment that is insufficient to permit the entity to finance its activities without additional subordinated financial support or whose equity investors lack the characteristics of a controlling financial interest. A VIE is consolidated by its primary beneficiary, which is the entity that, through its variable interests has both the power to direct the activities that significantly impact the VIE’s economic performance and the obligations to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. Consolidated VIEs FAR FAR securitizes certain of its interests in nonperforming reverse mortgages and non-agency one-to-four-family In February 2021, FAR executed its optional redemption of outstanding securitized notes related to outstanding nonperforming HECM securitizations. As part of the optional redemption, FAR paid off notes with an outstanding principal balance of $294.2 million. The notes were paid off at par. In April 2021, FAR executed its optional redemption of outstanding securitized notes related to outstanding non-agency FACo FACo securitizes certain of its interests in fix & flip mortgages. The transactions provide debt security holders the ability to invest in a pool of loans secured by an investment in real estate. The transactions provide FACo with access to liquidity for the loans and ongoing management fees. The principal and interest on the outstanding debt securities are paid using the cash flows from the underlying loans, which serve as collateral for the debt. In April 2021 , FACo executed its optional redemption of outstanding securitized notes related to the 2018 , 2019 , and 2020 (“ANTLR”)securitizations. As part of the optional redemption, FACo paid off notes with an outstanding principal balance of $175.3 million. The notes were paid off at par. Servicing Securitized Loans In their capacity as servicer of the securitized loans, FACo and FAR retain the power to direct the VIE’s activities that most significantly impact the VIEs economic performance. FACo and FAR also retain certain beneficial interests in these trusts which provide exposure to potential gains and losses based on the performance of the trust. As FACo and FAR have both the power to direct the activities that significantly impact the VIE’s economic performance and the obligations to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, the definition of primary beneficiary is met and the trusts are consolidated by the Company through its FACo and FAR subsidiaries. Certain obligations may arise from the agreements associated with transfers of loans. Under these agreements, the Company may be obligated to repurchase the loans, or otherwise indemnify or reimburse the investor for losses incurred due to material breach of contractual representations and warranties. There were no charge-offs associated with these transferred mortgage loans related to the standard securitization representations and warranties obligations for the Successor period from April 1, 2021 to December 31, 2021, or the Predecessor period from January 1, 2021 to March 31, 2021. There were $2.5 million and $0 realized losses associated with these transferred mortgage loans for the Predecessor years ended December 31, 2020 and 2019, respectively. The following table presents the assets and liabilities of the Company’s consolidated VIEs, which are included in the Consolidated Statements of Financial Condition and excludes intercompany balances, except for retained bonds and beneficial interests (in thousands): December 31, 2021 December 31, 2020 Successor Predecessor ASSETS Restricted cash $ 311,652 $ 293,580 Loans held for investment, subject to nonrecourse debt, at fair value 6,099,607 5,396,167 Other assets, net 67,593 79,528 TOTAL ASSETS $ 6,478,852 $ 5,769,275 LIABILITIES Nonrecourse debt, at fair value $ 6,088,298 $ 5,459,941 Payables and other liabilities 428 291 TOTAL VIE LIABILITIES 6,088,726 5,460,232 Retained bonds and beneficial interests eliminated in consolidation (231,229 ) (202,187 ) TOTAL CONSOLIDATED LIABILITIES $ 5,857,497 $ 5,258,045 Unconsolidated VIEs FACo In December 2021 , FACo established the Cavatica Asset Participation Trust (“CAPT”) for the purpose of securitizing agricultural loans. In 2021 , FACo executed CAPT-2021 , where FACo’s beneficial interest in the securitization is limited to its Issuer Residual Interest Certificates, a 5% eligible vertical interest in the Trust. The Company determined that the securitization structures meets the definition of a VIE and concluded that the Company does not hold a significant variable interest in the securitizations and the Company does not have the power to direct the activities that most significantly affect the economic performance of the VIEs. However, the transfer of the loans to the VIEs was determined not to be a sale. As such, the Company continues to recognize and consolidate the loans and the related nonrecourse liability, with the retained bonds being eliminated against the nonrecourse liability in consolidation.FACo’s continuing involvement with and exposure to loss from the VIE includes the carrying value of the retained bond, the retained loans, debt servicing of the related nonrecourse liability, servicing advances in the role as servicer, and obligations under representations and warranties contained in the loan sale agreements. Creditors of the VIE have no recourse to FACo’s assets or general credit. The underlying performance of the mortgage loans held has a direct impact on the fair values and cash flows of the beneficial interests held. As of December 31 , 2021 (Successor), the interests retained upon execution of the transaction consisted of an interest in the Issuer Residual Interest Certificates issued by the VIE and had an initial fair value of $9.3 million. The agricultural loans transferred to the VIE and the nonrecourse debt related to the transfer had an initial fair value of $166.1 million. Cash proceeds from the securitizations were $31.2 million. The Company did not record any gain or loss, as the transfer of loans to the VIE was determined not to be a sale. As of December 31, 2021 (Successor), the consolidated balance of the agricultural loans and the related nonrecourse liability transferred to the VIE had a fair value of $118.6 million million FAM FAM securitizes certain of its interests in agency-eligible residential mortgage loans. The transactions provide investors with the ability to invest in a pool of mortgage loans secured by one-to-four-family and concluded that the Company does not hold a significant variable interest in the securitizations and that the contractual role as servicer is not a variable interest. The transfer of the loans to the VIEs was determined to be a sale. The Company derecognized the mortgage loans and did not consolidate the trusts. FAM’s continuing involvement with and exposure to loss from the VIE includes the carrying value of the retained bond, the servicing asset recognized in the sale of the loans, servicing advances in the role as servicer, and obligations under representations and warranties contained in the loan sale agreements. Creditors of the VIE have no recourse to FAM’s assets or general credit. The underlying performance of the mortgage loans transferred has a direct impact on the fair values and cash flows of the beneficial interests held and the servicing asset recognized. As of December 31, 2021 (Successor), the interests retained upon transfer of the mortgage loans consisted of an interest in each class of securities issued by the VIE and had an initial fair value of $58.1 million. The servicing asset recognized upon sale of the mortgage loans to the VIE had an initial fair value of $4.4 million. Cash proceeds from the securitizations were $1,117.0 million and cash proceeds from retained bonds were $1.6 million. The Company recorded a gain on sale on the securitizations of $40.4 million.

Business Combinations [Abstract]
Acquisitions	4. Acquisitions The Business Combination On October 12, 2020, the Company, Replay and FoA Equity entered into the Transaction Agreement pursuant to which Replay agreed to combine with FoA Equity in a series of transactions that resulted in the Company becoming a publicly-traded company on the NYSE and controlling FoA Equity in an “UP-C” The Business Combination was accounted for using the acquisition method with the Company as the accounting acquirer. Under the acquisition method of accounting, the Company’s assets and liabilities were recorded at carrying value, and the assets and liabilities associated with FoA Equity were recorded at estimated fair value as of the Closing Date. The excess of the purchase price over the estimated fair values of the net assets acquired was recognized as goodwill. For accounting purposes, the acquirer is the entity that has obtained control of another entity and, thus, consummated a business combination. The determination of whether control has been obtained begins with the evaluation of whether control should be evaluated based on the variable interest or voting interest model. If the acquiree is a variable interest entity, the primary beneficiary would be the accounting acquirer. FoA Equity met the definition of a variable interest entity, and the Company was determined to be the primary beneficiary. As a result of the Business Combination, the Company’s financial statement presentation distinguishes FoA Equity as the “Predecessor” through the Closing Date. FoA is the “Successor” for periods after the Closing Date. Revenue and earnings from the date of acquisition to year end are shown as the “Sucessor” period on the Consolidated Statements of Operation. As a result of the application of the acquisition method of accounting in the Successor period, the consolidated financial statements for the Successor period are presented on a full step-up step-up The consolidated financial statements will not be retrospectively adjusted for any provisional amount changes that occur in subsequent periods. Rather, any provisional amount adjustments will be recognized during the reporting period in which the adjustments are determined. The Company will also be required to record, in the same period’s consolidated financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of any change to the provisional amounts, calculated as if the accounting had been completed at the Closing Date. The purchase price allocation, is substantially complete, except for certain tax adjustments that will be completed by March 31, 2022. The allocation will be finalized as soon as practicable, but no later than one year from the Closing Date. The following table summarizes the provisional estimated fair value of consideration transferred, noncontrolling interest equity value, assets acquired and liabilities assumed in conjunction with the Business Combination (in thousands): Consideration transferred: Total cash consideration $ 342,270 Blocker rollover equity 221,811 Seller earnout contingent consideration (1) 160,272 Tax receivable agreement obligations to the seller 31,950 Total consideration transferred 756,303 Noncontrolling interest 1,658,545 Total equity value $ 2,414,848 Assets acquired: Cash and cash equivalents $ 336,075 Restricted cash 305,292 Loans held for investment, subject to HMBS related obligations, at fair value 10,071,192 Loans held for investment, subject to nonrecourse debt, at fair value 5,291,443 Loans held for investment, at fair value 1,100,544 Loans held for sale, at fair value 2,140,361 Mortgage servicing rights, at fair value 267,364 Fixed assets and leasehold improvements, net 26,079 Intangible assets, net (2) 717,700 Other assets, net 404,864 Total assets acquired $ 20,660,914 Liabilities assumed: HMBS related obligations, at fair value $ 9,926,131 Nonrecourse debt, at fair value 5,227,942 Other financing lines of credit 3,340,345 Payables and other liabilities 669,048 Notes payable, net 353,924 Total liabilities assumed $ 19,517,390 Net identifiable assets acquired 1,143,524 Goodwill (3) $ 1,271,324 (1) Represents the estimated fair market value of earnout shares issued to Sellers, which will be settled with shares of Class A Common Stock and is accounted for as equity classified contingent consideration. These estimated fair values are preliminary and subject to adjustments in subsequent periods. (2) Intangible assets were identified that met either the separability criterion or contractual legal criterion. The evaluations of the facts and circumstances available as of April 1, 2021, to assign provisional fair values to assets acquired and liabilities assumed are ongoing, including the assessments of the economic characteristics of intangible assets. The indefinite lived trade names and definite lived trade names intangible assets represent the values of all the Company’s trade names. The broker/customer relationships intangible asset represents the existing broker/customer relationships. (3) Goodwill represents the excess of the gross consideration transferred over the provisional fair value of the underlying net tangible and identifiable intangible assets acquired. Goodwill represents future economic benefits arising from acquiring FoA Equity, primarily due to its strong market position and its assembled workforce that are not individually identified and separately recognized as intangible assets. Approximately $85.2 million of the goodwill recognized was expected to be deductible for income tax purposes at the acquisition date. There were certain transaction expenses contingent on the Closing (i.e. the change-in-control The following unaudited pro forma financial information presents the results of operations as if the Business Combination had occurred on January 1, 2020. The unaudited pro forma results may not necessarily reflect the actual results of operations that would have been achieved nor are they necessarily indicative of future results of operations.

On March 26, 2021, in order to expand its product base to home improvement loans, the Company acquired certain assets and operations of Renovate America, Inc. (“RAI”) (the “RAI Transaction”). The RAI Transaction met the requirements to be considered a business combination under ASC 805. The assets purchased and liabilities assumed from the RAI Transaction have been recorded at fair market value and included in the Company’s consolidated financial statements from the date of the RAI Transaction. The Company has allocated the purchase price to the tangible and identifiable intangible assets based on their estimated fair market values at the date of the RAI Transaction as required under ASC 805. The excess of the purchase price over the fair value of the net identifiable tangible and intangible assets was recorded as goodwill. The goodwill generated by the RAI Transaction is expected to be deductible for U.S. federal income tax purposes. As a result of the RAI Transaction, for accounting purposes, FAM was deemed to be the accounting acquirer and RAI was deemed to be the accounting acquiree. The RAI Transaction was accounted for using the acquisition method of accounting and the fair value of the total purchase consideration transferred was $43.5 million, including cash and the relief of obligations owed to FAM by the DIP of RAI. There was no contingent consideration as part of the RAI Transaction. Goodwill is comprised of expected future benefits for the Company and the assembled workforce acquired in the RAI Transaction, which do not qualify as separately recognized intangible assets. Goodwill associated with the RAI Transaction is assigned to the Company’s Mortgage Originations reportable segment, which represents the Company’s reporting unit that is expected to benefit from the assembled workforce acquired in the RAI Transaction. The following table sets forth the fair values of the assets acquired in connection with the RAI Transaction (in thousands): Acquisition date Loans held for sale, at fair value $ 35,226 Intangible assets—Technology 1,890 Goodwill 5,627 Other assets, net 753 Net assets acquired $ 43,496 The acquired loans held for sale had a UPB of $36.6 million as of the acquisition date, and have been subsequently sold as of December 31, 2021. Parkside Lending, LLC On May 14, 2021, in order to further strengthen its position in the wholesale mortgage originations, the Company acquired certain assets and operations of Parkside Lending, LLC (“Parkside”). The Company acquired certain key contracts and real property leases, as well as proprietary materials, intellectual property, and workforce (the “Parkside Transaction”). The Parkside Transaction met the requirements to be considered a business combination under ASC 805. Parkside’s accounts, affected for preliminary adjustments to reflect fair market values assigned to assets purchased and liabilities assumed, and results of operations, are included in the Company’s consolidated financial statements from the date of the Parkside Transaction. The Company has allocated the purchase price to the tangible and identifiable intangible assets based on their estimated fair market values at the date of the Parkside Transaction as required under ASC 805. The excess of the purchase price over the fair value of the net identifiable tangible and intangible assets was recorded as goodwill. As a result of the Parkside Transaction, for accounting purposes, FAM was deemed to be the accounting acquirer and Parkside was deemed to be the accounting acquiree. The Parkside Transaction was accounted for using the acquisition method of accounting and the fair value of the total purchase consideration transferred was $32.6 million, all of which was cash consideration, including the present value of deferred payments to be made to the sellers over the three years subsequent to closing of $12.6 million. There was no contingent consideration as part of the Parkside Transaction. Goodwill is comprised of expected future benefits for the Company and the assembled workforce acquired in the Parkside Transaction, which do not qualify as separately recognized intangible assets. Goodwill associated with the Parkside Transaction is assigned to the Company’s Mortgage Originations reportable segment, which represents the Company’s reporting unit that is expected to benefit from the assembled workforce acquired in the Parkside Transaction. The following table sets forth the fair values of the assets acquired in connection with the Parkside Transaction (in thousands): Acquisition date Intangible assets—Broker Relationships $ 10,200 Goodwill 22,400 Other assets, net 13 Net assets acquired $ 32,613 Additional disclosures required by ASC 805 with respect to the RAI and Parkside acquisitions have been omitted because the information is immaterial to the financial statements.

Fair Value Disclosures [Abstract]
Fair Value	5. Fair Value Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is based on the assumptions market participants would use when pricing an asset or liability and follows a fair value hierarchy that prioritizes the information used to develop those assumptions. The fair value hierarchy gives the highest priority to quoted prices available in active markets (i.e., observable inputs) and the lowest priority to data lacking transparency (i.e., unobservable inputs). In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. An instrument’s categorization within the fair value hierarchy is based on the lowest level of significant input to its valuation. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. All aspects of nonperformance risk, including the Company’s own credit standing, are considered when measuring the fair value of a liability. Following is a description of the three levels: Level 1 Inputs: Quoted prices for identical instruments in active markets. Level 2 Inputs: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 Inputs: Instruments with unobservable inputs that are significant to the fair value measurement. The Company classifies assets and liabilities in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company recognizes transfers between levels of the fair value hierarchy as of the end of the reporting period. There were no transfers within the hierarchy for the Successor period from April 1, 2021 to December 31, 2021 or for the Predecessor period from January 1, 2021 to March 31, 2021. There were no transfers for the Predecessor for the years ended December 31, 2020 and 2019. Following are descriptions of the valuation methodologies used to measure material assets and liabilities at fair value and the details of the valuation models, key inputs to those models and significant assumptions utilized. Within the assumption tables presented, not meaningful (“NM”) refers to a range of inputs that is too broad to provide meaningful information to the user or to an input that has no range and consists of a single data point. Loans Held for Investment, Subject to HMBS Related Obligations, at Fair Value HECM loans securitized into Ginnie Mae HMBS are not actively traded in open markets with readily observable market prices. The Company values HECM loans securitized into Ginnie Mae HMBS utilizing a present value methodology that discounts estimated projected cash flows over the life of the loan portfolio using prepayment, borrower mortality, borrower draw and discount rate assumptions management believes a market participant would use in estimating fair value. The significant unobservable inputs used in the measurement include: Conditional Repayment Rate—The Company projects borrower prepayment rates which considers borrower age and gender and is based on historical termination rates. The outputs of borrower prepayment rates, which include both voluntary and involuntary prepayments, are utilized to anticipate future terminations. Loss Frequency and Severity—Termination proceeds are adjusted for expected loss frequencies and severities to arrive at net proceeds that will be provided upon final resolution. Loss frequency and severity represent the frequency of losses and the losses associated with loans that are liquidated through a foreclosure sale, net of claim proceeds. Historical experience is utilized to estimate the loss rates resulting from scenarios where FHA insurance proceeds are not expected to cover all principal and interest outstanding and, as servicer, the Company is exposed to losses upon resolution of the loan. Loss frequency and severity are based upon the historical experience with specific loan resolution waterfalls. Discount Rate—derived based upon reference to yields required by market participants for recent transactions in the HECM loan bulk market adjusted based upon weighted average life of the loan portfolio. This rate reflects what the Company believes to be a market participant’s required yield on HECM loans of similar weighted average lives. The yield spread is applied over an interpolated benchmark curve or as a spread over a collateral forward curve. Average Draw Rates—The draw curve is estimated based upon the historical experience with the specific product type contemplating the borrower’s age and loan age. Changes to any of these assumptions could result in significantly different valuation results. The Company classifies reverse mortgage loans held for investment as Level 3 assets within the GAAP hierarchy, as they are dependent on unobservable inputs. The following table presents the weighted average significant unobservable assumptions used in the fair value measurement of loans held for investment, subject to HMBS related obligations, for the periods indicated: December 31, 2021 December 31, 2020 Successor Predecessor Unobservable Assumptions Range Weighted Average Range Weighted Average Conditional repayment rate NM 20.8 % NM 20.0 % Loss frequency NM 4.5 % NM 4.4 % Loss severity 3.1% - 7.7% 3.3 % 5.1% - 13.3% 5.4 % Discount rate NM 2.4 % NM 1.6 % Average draw rate NM 1.1 % NM 1.1 % The Company aggregates loan portfolios based upon the underlying securitization trust and values these loans using these aggregated pools.

The range of inputs provided above are based upon the range of inputs utilized for each securitization trust. Commercial Mortgage Loans Fix & Flip—Securitized The securitized Fix & Flip loans are short-term loans for individual real estate investors, with terms ranging from 9—24 months. This product is valued using a DCF model. The Company classifies these mortgage loans as Level 3 assets within the GAAP hierarchy. The Company utilized the following weighted average assumptions in estimating the fair value of securitized Fix & Flip mortgage loans for the periods indicated: December 31, 2021 December 31, 2020 Successor Predecessor Unobservable Assumptions Range Weighted Average Range Weighted Average Prepayment rate (SMM) NM 14.1 % NM 17.1 % Discount rate NM 5.7 % 6.7% - 10.0% 6.7 % Loss frequency 0.3% - 69.0% 0.6 % 0.2% - 44.0% 0.6 % The Company aggregates loan portfolios based upon the underlying securitization trust and values these loans using these aggregated pools.

Loans Held for Investment, at Fair Value Reverse Mortgage Loans Reverse mortgage loans held for investment, at fair value, consists of originated or purchased HECM and non-agency Originated or purchased HECM loans held for investment are valued predominantly by utilizing forward HMBS prices for similar pool characteristics and based on observable market data. These amounts are further adjusted to include future cash flows that would be earned for servicing the HECM loan over the life of the asset. Unsecuritized tails consists of performing and nonperforming repurchased loans. The fair value of performing unsecuritized tails are valued at current pricing levels for similar Ginnie Mae HMBS. The fair value of nonperforming unsecuritized tails is based on expected claim proceeds from HUD upon assignment of the loans. The fair value of repurchased loans is based on expected cash proceeds of the liquidation of the underlying properties and expected claim proceeds from HUD. The primary assumptions utilized in valuing nonperforming repurchased loans include loss frequency and loss severity. Termination proceeds are adjusted for expected loss frequencies and severities to arrive at net proceeds that will be provided upon final resolution, including assignments to FHA. Historical experience is utilized to estimate the loss rates resulting from scenarios where FHA insurance proceeds are not expected to cover all principal and interest outstanding and, as servicer, the Company is exposed to losses upon resolution of the loan. The Company classifies reverse mortgage loans held for investment, at fair value as Level 3 assets within the GAAP hierarchy. Inventory Buyouts The fair value of Inventory Buyouts is based on the expected cash proceeds of the liquidation of the underlying properties and expected claim proceeds from HUD. The primary assumptions utilized in valuing Inventory Buyouts include loss frequency and loss severity. Termination proceeds are adjusted for expected loss frequencies and severities to arrive at net proceeds that will be provided upon final resolution, including assignments to FHA. Historical experience is utilized to estimate the loss rates resulting from scenarios where FHA insurance proceeds are not expected to cover all principal and interest outstanding and, as servicer, the Company is exposed to losses upon resolution of the loan. The Company values Inventory Buyouts utilizing a present value methodology that discounts estimated projected cash flows over the life of the portfolio.

Reverse mortgage loans held for sale consists primarily of performing repurchased loans. The fair value of performing unpoolable loans is based on expected claim proceeds from HUD upon assignment of the loans. In certain instances the loan balance may exceed the MCA. In these instances, the fair value is based on expected proceeds from sale of the underlying property and any additional HUD claim proceeds. The Company classifies reverse mortgage loans held for sale, at fair value as Level 3 assets within the GAAP hierarchy. Residential and Commercial Mortgage Loans Mortgage loans held for sale include residential and commercial mortgage loans originated by the Company and held until sold to secondary market investors. The Company primarily originates conventional GSEs and residential mortgage loans held for sale and commercial loans held for sale. Residential Mortgage Loans The Company originates or purchases mortgage loans in the U.S. that it intends to sell to FNMA, FHLMC, and Ginnie Mae (collectively “the Agencies”). Additionally, the Company originates or purchases mortgage loans in the U.S. that it intends to sell into the secondary markets via whole loan sales. Mortgage loans held for sale are typically pooled and sold into certain exit markets, depending upon underlying attributes of the loan, such as agency eligibility, product type, interest rate, and credit quality. In addition, the Company may originate loans that do not meet specific underwriting criteria and are not eligible to be sold to the Agencies. Two valuation methodologies are used to determine the fair value of mortgage loans held for sale. The methodology used depends on the exit market as described below: Loans valued using observable market prices for identical or similar assets non-agency Loans valued using internal models Commercial Mortgage Loans The Company primarily originates two separate commercial loan products that it classifies as held for sale: Single Rental Loan (“SRL”) and Portfolio Lending. SRL The SRL product is designed for small/individual real estate investors looking to purchase and then rent out a single property. These are 30-year The Company utilized the following weighted average assumptions in estimating the fair value of SRL mortgage loans held for sale for the periods indicated: December 31, 2021 December 31, 2020 Successor Predecessor Unobservable Assumptions Range Weighted Average Range Weighted Average Prepayment rate (CPR) 1.0% - 17.1% 14.2 % 1.0% - 17.1% 15.4 % Discount rate NM 3.3 % NM 5.0 % Default rate (CDR) 1.0% - 57.2% 2.2 % 1.0% - 64.9% 3.6 % Portfolio Lending The Portfolio Lending product is designed for larger investors with multiple properties. Specifically, these loans are useful for consolidating multiple rental property mortgages into a single loan. These loans have fixed coupons that typically range from 5.0 6.2 10-year 30-year The Company utilized the following weighted average assumptions in estimating the fair value of Portfolio Lending mortgage loans held for sale for the periods indicated: December 31, 2021 December 31, 2020 Successor Predecessor Unobservable Assumptions Range Weighted Average Range Weighted Average Prepayment rate (CPR) 0.0% - 14.5% 8.7 % 0% - 15.0% 9.3 % Discount rate NM 3.9 % NM 4.9 % Default rate (CDR) 1.0% - 54.0% 3.2 % 1.0% - 42.7% 2.0 % Fix & Flip The Fix & Flip loans are short-term loans for individual real estate investors, with terms ranging from 9 The Company utilized the following weighted average assumptions in estimating the fair value of fix & flip mortgage loans for the periods indicated: December 31, 2020 Predecessor Unobservable Assumptions Range Weighted Average Prepayment rate (SMM) NM 12.4 % Discount rate 6.7% - 10.0% 7.2 % Loss frequency NM 0.8 % As of March 2021, management made the decision to change the classification of fix & flip loans from loans held for sale, at fair value, to loans held for investment, at fair value. Mortgage Servicing Rights (FAM) As of December 31, 2021 (Successor) and December 31, 2020 (Predecessor), the Company valued MSRs internally. The significant assumptions utilized to determine fair value are projected prepayments using the Public Securities Association Standard Prepayment Model, discount rates, and projected servicing costs that vary based on the loan type and delinquency. The Company classifies these valuations as Level 3 assets within the GAAP hierarchy since they are dependent on unobservable inputs. Fair value is derived through a DCF analysis and calculated using a computer pricing model. This computer valuation is based on the objective characteristics of the portfolio (loan amount, note rate, etc.) and commonly used industry assumptions (Prepayment speed assumptions (“PSA”), discount rate, etc.). The assumptions taken into account by the pricing model are those which many active purchasers of servicing employ in their evaluations of portfolios for sale in the secondary market. The unique characteristics of the secondary servicing market often dictate adjustments to parameters over short periods of time. Subjective factors are also considered in the derivation of fair values, including levels of supply and demand for servicing, interest rate trends, and perception of risk not incorporated into prepayment assumptions. Fair value is defined as the estimated price at which the servicing rights would change hands in the marketplace between a willing buyer and seller. The valuation assumes that neither party would be under any compulsion to buy or sell and that each has reasonably complete and accurate knowledge of all relevant aspects of the offered servicing. The fair values represented in this analysis have been derived under the assumptions that sufficient time would be available to market the portfolio. The following tables summarize certain information regarding the servicing portfolio of retained MSRs for the periods indicated: December 31, 2021 December 31, 2020 Successor Predecessor Capitalization servicing rate 1.1 % 0.8 % Capitalization servicing multiple 4.4 3.2 Weighted average servicing fee (in basis points) 25 25 The Company utilized the following weighted average assumptions in estimating the fair value of MSRs: December 31, 2021 December 31, 2020 Successor Predecessor Unobservable Assumptions Range Weighted Average Range Weighted Average Weighted average prepayment speed (CPR) 0 12.8 8.3 % 6.6 24.9 12.1 % Discount rate NM 8.5 % NM 12.1 % Weighted average delinquency rate 0.8 14.3 1.3 % 1.2 9.2 1.3 % The following table summarizes the estimated change in the fair value of MSRs from adverse changes in the significant assumptions (in thousands): December 31, 2021 Successor Weighted Average Discount Weighted Average Impact on fair value of 10% adverse change $ (6,078 ) $ (15,708 ) $ (345 ) Impact on fair value of 20% adverse change (11,843 ) (30,230 ) (691 ) These sensitivities are hypothetical and should be evaluated with care. The effect on fair value of a 10% variation in assumptions generally cannot be determined because the relationship of the change in assumptions to the fair value may not be linear. Additionally, the impact of a variation in a particular assumption on the fair value is calculated while holding other assumptions constant. In reality, changes in one factor may lead to changes in other factors, which could impact the above hypothetical effects. Investments, at Fair Value The Company invests in the equity of other companies in the form of common stock, preferred stock, or other in-substance Derivative Assets and Liabilities Some of the derivatives held by the Company are exchange-traded or traded within highly active dealer markets. In order to determine the fair value of these instruments, the Company utilizes the exchange price or dealer market price for the particular derivative contract; therefore, these contracts are classified as Level 1 in the fair value hierarchy. The Company executes derivative contracts, including forward commitments, TBAs, interest rate swaps, and interest rate swap futures, as part of its overall risk management strategy related to its reverse mortgage and commercial loan portfolios. The value of the forward commitments is estimated using current market prices for HMBS and are considered Level 2 in the fair value hierarchy. TBAs are valued based on forward dealer marks from the Company’s approved counterparties and are considered Level 2 in the fair value hierarchy. The value of interest rate swaps and interest rate swap futures is based on the exchange price or dealer market prices. The Company classifies interest rate swaps as Level 2 in the fair value hierarchy. The Company classifies interest rate swap futures as Level 1 in the fair value hierarchy. The value of the forward MBS is based on forward prices with dealers in such securities or internally-developed third party models utilizing observable market inputs. The Company classifies forward MBS as Level 2 in the fair value hierarchy. In addition, the Company enters into IRLCs with prospective borrowers. Commitments to fund residential mortgage loans with potential borrowers are a binding agreement to lend funds to these potential borrowers at a specified interest rate within a specified period of time. The fair value of IRLCs is derived from the fair value of similar mortgage loans or bonds, which is based on observable market data. Changes to the fair value of IRLCs are recognized based on changes in interest rates, changes in the probability that the commitment will be exercised (pull through factor), and the passage of time. The expected net future cash flows related to the associated servicing of the loan are included in the fair value measurement of IRLCs. The Company adjusts the outstanding IRLCs with prospective borrowers based on an expectation that it will be exercised and the loan will be funded. Given the unobservable nature of the pull through factor, IRLCs are classified as Level 3 in the fair value hierarchy. HMBS Related Obligations, at Fair Value The HMBS related obligation valuation considers the obligation to pass FHA insured cash flows through to the beneficial interest holders (repayment of secured borrowing) of the HMBS securities and the servicer and issuer obligations of the Company. The valuation of the obligation to repay the secured borrowing is estimated using Level 3 unobservable market inputs. The estimated fair value is based on the net present value of projected cash flows over the estimated life of the liability. The estimated fair value of the HMBS related obligations also includes the consideration required by a market participant to transfer the HECM and HMBS servicing obligations, including exposure resulting from shortfalls in FHA insurance proceeds. The Company’s valuation considers assumptions that it believes a market participant would consider in valuing the liability, including, but not limited to, assumptions for repayment, costs to transfer servicing obligations, shortfalls in FHA insurance proceeds, and discount rates. The significant unobservable inputs used in the measurement include: Borrower Repayment Rates—the conditional repayment rate curve considers borrower age and gender and is based on historical termination rates. Discount Rate—derived based on an assessment of current market yields and spreads that a market participant would consider for entering into an obligation to pass FHA insured cash flows through to holders of the HMBS beneficial interests. Yield spread applied over interpolated benchmark curve or as a spread over collateral forward curve. The following table presents the weighted average significant unobservable inputs used in the fair value measurement of HMBS related obligations for the periods indicated: December 31, 2021 December 31, 2020 Successor Predecessor Unobservable Assumptions Range Weighted Average Range Weighted Average Conditional repayment rate NM 20.8 % NM 19.9 % Discount rate NM 2.3 % NM 1.4 % Nonrecourse Debt, at Fair Value Reverse Mortgage Loans Outstanding notes issued that are securitized by nonrecourse debt are paid using the cash flows from the underlying reverse mortgage loans, which serve as collateral for the debt. The fair value of nonrecourse debt is estimated using Level 3 unobservable market inputs. The estimated fair value is based on the net present value of projected cash flows over the estimated life of the liability. The significant unobservable inputs used in the measurement include: Weighted Average Remaining Life—The projected remaining life is based on the expected conditional prepayment rate, which is utilized to determine future terminations. Borrower Repayment Rates—The conditional repayment rate curve considers borrower age and gender and is based on historical termination rates. Discount Rate—derived based on an assessment of current market yields and spreads that a market participant would consider for entering into an obligation to pass FHA insured cash flows through to holders of the HMBS beneficial interests. Yield spread applied over interpolated benchmark curve or as a spread over collateral forward curve. The Company’s valuation considers assumptions that it believes a market participant would consider in valuing the liability, including, but not limited to, assumptions for prepayment and discount rates. The following table presents the weighted average significant unobservable assumptions used in the fair value measurements of nonrecourse debt for the periods indicated: December 31, 2021 December 31, 2020 Successor Predecessor Unobservable Assumptions Range Weighted Average Range Weighted Average Performing/Nonperforming HECM securitizations Weighted average remaining life (in years) 0.2 - 0.8 0.5 0.2 - 1.5 1.0 Conditional repayment rate 30.8% - 54.4% 43.5 % 34.3% - 56.3% 42.8 % Discount rate NM 2.3 % NM 3.1 % Securitized Non-Agency Weighted average remaining life (in years) 1.0 - 2.3 1.6 0.3 - 2.7 2.1 Conditional repayment rate 18.4% - 35.9% 28.2 % 19.6% - 35.8% 23.9 % Discount rate NM 2.2 % NM 2.2 % Commercial Mortgage Loans Outstanding nonrecourse notes issued that are securitized by loans held for investment, subject to nonrecourse debt, are paid using the cash flows from the underlying mortgage loans. The fair value of nonrecourse debt is estimated using Level 3 unobservable market inputs. The estimated fair value is based on the net present value of projected cash flows over the estimated life of the liability. The Company’s valuation considers assumptions that it believes a market participant would consider in valuing the liability, including, but not limited to, assumptions for prepayment and discount rates. The Company estimates prepayment speeds giving consideration that the Company may in the future transfer additional loans to the trust, subject to the availability of funds provided for within the trust. The following table presents the significant unobservable assumptions used in the fair value measurements of nonrecourse debt for the periods indicated: December 31, 2021 December 31, 2020 Successor Predecessor Unobservable Assumptions Range Weighted Average Range Weighted Average Weighted average remaining life (in months) NM 4.0 1.9 - 4.1 3.4 Weighted average prepayment speed (SMM) NM 14.0 % 17.7% - 32.0% 21.4 % Discount rate NM 3.1 % NM 5.8 % Deferred Purchase Price Liabilities Deferred purchase price liabilities are measured using a present value of future payments which considers various assumptions, including future loan origination volumes, projected earnings and discount rates. As of December 31, 2021 (Successor) and December 31, 2020 (Predecessor), the Company utilized discount rates ranging from 8% to 35% to value the deferred purchase price liabilities. The liabilities as of December 31, 2021 (Successor) include provisional estimates for the seller earnout provision related to the Parkside asset purchase agreement that was based on the information that was available as of the acquisition date. Refer to Note 4—Acquisitions for additional details regarding this acquisitions. As this value is largely based on unobservable inputs, the Company classifies this liability as Level 3 in the fair value hierarchy. TRA Obligation The fair value of the TRA obligation resulting from the exchanges at the Business Combination Closing Date is derived through the use of a DCF model. The significant assumptions used in the DCF include the ability to utilize tax attributes based on current tax forecasts, a constant U.S. federal income tax rate and an assumed weighted average state and local income tax rate, and a 13.5% discount rate applied to future payments under the Tax Receivable Agreements. The Company classifies the TRA obligation as Level 3 in the fair value hierarchy. Nonrecourse MSR Financing Liability The Company has sold to certain third parties the right to receive all excess servicing and ancillary fees related to identified MSRs in exchange for an upfront payment equal to the entire purchase price of the identified MSRs. The Company has elected to account for the servicing liability using the fair value option. Consistent with the underlying MSRs, fair value is derived through a DCF analysis and calculated using a computer pricing model. This computer valuation is based on the objective characteristics of the portfolio (loan amount, note r

Goodwill is reviewed for impairment utilizing either a qualitative assessment or a quantitative goodwill impairment test. Because of a significant and sustained decline in stock price and market capitalization, the Company determined it was necessary to perform a quantitative goodwill impairment test. The Company estimated the fair value of all reporting units utilizing a market approach and the significant assumptions used to measure fair value include discount rate, terminal factors, market multiples and control premiums. The Company confirmed the reasonableness of the estimated reporting unit fair values by reconciling those fair values to its enterprise value and market capitalization. As a result of its annual impairment test, the Company recognized an impairment to goodwill of $ million. During the fourth quarter, the Company’s stock price experienced an additional sustained decline, triggering an interim impairment analysis as of December 31, 2021, which resulted in recognition of additional impairment of the remaining goodwill of $335.5 million. This impairment charge was recognized in impairment of goodwill and intangible assets in the Consolidated Statements of Operations, but does not negatively impact tangible book value.

Line of Credit Facility [Abstract]
Other Financing Lines of Credit	19. Other Financing Lines of Credit Mortgage facilities These facilities are generally structured as master repurchase agreements under which ownership of the related eligible loans is temporarily transferred to a lender or as participation arrangements pursuant to which the lender acquires a participation interest in the related eligible loans. The funds advanced are generally repaid using the proceeds from the sale or securitization of the loans to, or pursuant to, programs sponsored by FNMA, FHLMC, and Ginnie Mae or to private secondary market investors, although prior payment may be required based on, among other things, certain breaches of representations and warranties or other events of default. When these facilities are drawn on, the Company generally must transfer and pledge eligible loans to the lender and comply with various financial and other covenants. The facilities expire at various times during 2022 through 2026. Under the facilities, loans are generally transferred at an advance rate less than the principal balance or fair value of the loans, which serves as the primary credit enhancement for the lender. One of the warehouse lines of credit is also guaranteed by FAH, a wholly owned subsidiary and the parent holding company to the mortgage business. Since the advances are generally for less than 100% of the principal balance of the loans, working capital is required to fund the remaining portion of the principal balance of the loans. The amount of the advance that is provided under the various facilities ranges from 94% to 100% of the market value or principal balance of the loans. Upon expiration, management believes it will either renew its existing warehouse facilities or obtain sufficient additional lines of credit. Reverse mortgage facilities These facilities are generally structured as master repurchase agreements under which ownership of the related eligible loans is temporarily transferred to a lender or as participation arrangements pursuant to which the lender acquires a participation interest in the related eligible loans. The funds advanced are generally repaid using the proceeds from the sale or securitization of the loans to, or pursuant to, programs sponsored by Ginnie Mae or private secondary market investors, although prior payment may be required based on, among other things, certain breaches of representations and warranties or other events of default. When the warehouse lines of credit are drawn on, the Company generally must transfer and pledge eligible loans and comply with various financial and other covenants. The facilities expire at various times during 2022 through 2024. Under the facilities, loans are transferred at an advance rate less than the principal balance or fair value of the loans, which serves as the primary credit enhancement for the lender. Since the advances are generally for less than 100% of the principal balance of the loans, working capital is required to fund the remaining portion of the principal balance of the loan. The amount of the advance that is provided under the various facilities ranges from 90% to 104% of the market value or principal balance of the loans. Upon expiration, management believes it will either renew its existing facilities or obtain sufficient additional lines of credit. Commercial loan facilities These facilities are either structured as master repurchase agreements under which ownership of the related eligible loans is temporarily transferred to a lender or are collateralized by first lien loans or crop loans. The funds advanced are generally repaid using the proceeds from the sale or securitization of the loans to private secondary market investors, although prior payment may be required based on, among other things, certain breaches of representations and warranties or other events of default. When these facilities are drawn on, the Company must transfer and pledge eligible loan collateral and comply with various financial and other covenants. The facilities expire at various times during 2022 through 2023. Under the facilities, loans are transferred at an advance rate less than the principal balance or fair value of the loans, which serves as the primary credit enhancement for the lender. Two of the warehouse lines of credit are guaranteed, one fully and one limited, by FAH, a wholly owned subsidiary and the parent holding company to the commercial lending business. Since the advances are generally for less than 100% of the principal balance of the loans, working capital is required to fund the remaining portion of the principal balance of the loans. The amount of the advance that is provided under the various facilities generally ranges from 70% to 85% of the principal balance of the loans. Upon expiration, management believes it will either renew its existing facilities or obtain sufficient additional lines of credit.

Repurchase Reserves

Repurchase Reserves	12 Months Ended

Repurchase Reserves Disclosure [Abstract]
Repurchase Reserves Disclosure	22. Repurchase Reserves Certain whole loan sale contracts include provisions requiring the Company to repurchase a loan if a borrower fails to make certain initial loan payments due to the acquirer or if the accompanying mortgage loan fails to meet customary representations and warranties made by the Company when the loans were sold. These representations and warranties are made to the loan purchasers about various characteristics of the loans, such as manner of origination, the nature and extent of underwriting standards applied and the types of documentation being provided and typically are in place for the life of the loan. In the event of a breach of the representations and warranties, the Company may be required to either repurchase the loan or indemnify the purchaser for losses it sustains on the loan. In addition, an investor may request that the Company refund a portion of the premium paid on the sale of loans if a loan is prepaid within a certain amount of time from the date of sale. Although a breach of a representation and warranty may result in a repurchase demand at any time, the Company believes that most repurchase requests occur within the first five years of the origination of the loan. The Company records a provision for estimated repurchases and premium recapture on loans sold, which is charged to gain on sale and other income from loans held for sale, net, on the Consolidated Statements of Operations. The current unpaid principal balance of loans sold by the Company represents the maximum potential exposure to repurchases related to representations and warranties. Reserve levels are a function of expected losses based on actual pending and expected claims, repurchase requests, historical experience, and loan sale volume. While the amount of repurchases and premium recapture is uncertain, the Company considers the liability to be appropriate. Repurchase reserves are included in payables and other liabilities on the Consolidated Statements of Financial Condition. The activity of the outstanding repurchase reserves was as follows (in thousands): December 31, 2021 December 31, 2020 Successor Predecessor Repurchase reserves, beginning of period $ 10,529 $ 3,118 Additions 9,234 24,186 Charge-offs (11,078 ) (16,775 ) Repurchase reserves, end of period $ 8,685 $ 10,529

At any time prior to November 15, 2022, FOAF may redeem some or all of the Notes at a redemption price equal to 100% of the principal amount thereof, plus the applicable premium as of the redemption date under the terms of the indenture and accrued and unpaid interest. The redemption price during each of the twelve-month periods following November 15, 2022, November 15, 2023 and at any time after November 15, 2024 is 103.938%, 101.969% and 100.000%, respectively, of the principal amount plus accrued and unpaid interest thereon. At anytime prior to November 15, 2022, FOAF may also redeem up to 40% of the aggregate principal amount of the notes at a redemption price equal to 107.875% of the aggregate principal amount of the senior unsecured notes redeemed, with an amount equal to or less than the net cash proceeds from certain equity offerings, plus accrued and unpaid interest. Upon the occurrence of a change of control, the holders of the Notes will have the right to require FOAF to make an offer to repurchase each holder’s Notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest. The Notes contain covenants limiting, among other things, FOAF and its restricted subsidiaries’ ability to incur additional debt or issue certain preferred shares, incur liens, make certain distributions, investments and other restricted payments, engage in certain transactions with affiliates, and merge or consolidate or sell, transfer, lease or otherwise dispose of all or substantially all of FOAF’s assets. These incurrence based covenants are subject to exceptions and qualifications. Many of these covenants will cease to apply during any time that the Notes have investment grade ratings and no default has occurred and is continuing. The Company was in compliance with all required covenants related to the Notes as of December 31, 2021. In addition, in 2017, the Company entered into an agreement for the purchase of computer hardware and equipment which was financed by notes payable to the seller with monthly payments through January 2021.

Litigation [Abstract]
Litigation	25. Litigation The Company’s business is subject to legal proceedings, examinations, investigations and reviews by various federal, state and local regulatory and enforcement agencies as well as private litigants such as the Company’s borrowers or former employees. At any point in time, the Company may have open investigations with regulators or enforcement agencies, including examinations and inquiries related to its loan servicing and origination practices. These matters and other pending or potential future investigations, examinations, inquiries or lawsuits may lead to administrative or legal proceedings, and possibly result in remedies, including fines, penalties, restitution, alterations in business practices, or additional expenses and collateral costs. As a litigation or regulatory matter develops, the Company, in conjunction with any outside counsel handling the matter, evaluates on an ongoing basis whether such matter presents a loss contingency that is probable and estimable. If, at the time of evaluation, the loss contingency is not both probable and reasonably estimable, the matter will continue to be monitored for further developments that would make such loss contingency both probable and reasonably estimable. Once the matter is deemed to be both probable and reasonably estimable, the Company will establish an accrued liability and record a corresponding amount to litigation related expense. The Company will continue to monitor the matter for further developments that could affect the amount of the accrued liability that has been previously established. For certain matters, the Company may consider a loss to be probable but cannot calculate a precise estimate of losses. For these matters, the Company may be able to estimate a range of possible loss. In determining whether it is possible to provide an estimate of loss or range of possible loss, the Company reviews and evaluates its material litigation and regulatory matters on an ongoing basis, in conjunction with any outside counsel handling the matter. As of December 31, 2021 (Successor), there were no matters that the Company considered to be probable or reasonably possible for which they could estimate losses or a reasonable range of estimated losses. The Company is a defendant in four representative lawsuits alleging violations of the California Labor Code and brought pursuant to the California Private Attorneys General Act (“PAGA”). The cases have been coordinated and currently are in discovery. Due to the unpredictable nature of litigation generally, and the wide discretion afforded the Court in awarding civil penalties in PAGA actions, the outcome of these matters cannot be presently determined, and a range of possible losses cannot be reasonably estimated. Although the actions are being vigorously defended, the Company could, in the future, incur judgments or enter into settlements of claims that could have a negative effect on its results of operations in any particular period. Legal expenses, which includes, among other things, settlements and the fees paid to external legal service providers, were $10.8 million for the Successor period from April 1, 2021 to December 31, 2021, and $4.2 million for the Predecessor period from January 1, 2021 to March 31, 2021. Legal expenses for the Predecessor were $19.5 million and $9.0 million for the years ended December 31, 2020 and 2019, respectively. These expenses are included in general and administrative expenses in the Consolidated Statements of Operations.

Commitments and Contingencies	26. Commitments and Contingencies Servicing of Mortgage Loans The Company has contracted with third party providers to perform specified servicing functions on its behalf. These services include maintaining borrower contact, facilitating borrower advances, generating borrower statements, collecting and processing payments of interest and principal and facilitating loss-mitigation strategies in an attempt to keep defaulted borrowers in their homes. For reverse mortgages, defaults on loans leading to foreclosures may occur if borrowers fail to meet maintenance obligations, such as payment of taxes or home insurance premiums. When a default cannot be cured, the sub-servicers sub-servicers Additionally, the sub-servicers sub-servicers Contractual sub-servicing sub-servicer Unfunded Commitments The Company is required to fund further borrower advances (where the borrower has not fully drawn down the HECM, non-agency The outstanding unfunded commitments available to borrowers related to agency and non-agency The Company also has commitments to purchase and sell loans totaling $ million and $ , respectively, at December , (Successor), compared to $ million and $ million, respectively, at December , (Predecessor). Mandatory Repurchase Obligation The Company is required to repurchase reverse loans out of the Ginnie Mae securitization pools once the outstanding principal balance of the related HECM is equal to or greater than 98% of the MCA. Performing repurchased loans are conveyed to HUD and nonperforming repurchased loans are generally liquidated in accordance with program requirements. Loans are considered nonperforming upon events including, but not limited to, the death of the mortgagor, the mortgagor no longer occupying the property as their principal residence, or the property taxes or insurance are not being paid. As an issuer of HMBS, the Company also has the option to repurchase reverse loans out of the Ginnie Mae securitization pools without prior approval from Ginnie Mae in certain instances. These situations include the borrower requesting an additional advance that causes the outstanding principal balance to be equal to or greater than 98% of the MCA; the borrower’s loan becoming due and payable under certain circumstances; the borrower not occupying the home for greater than twelve consecutive months for physical or mental illness, and the home is not the residence of another borrower; or the borrower failing to perform in accordance with the terms of the loan. For each HECM loan that the Company securitizes into Agency HMBS, the Company is required to covenant and warrant to Ginnie Mae, among other things, that the HECM loans related to each participation included in the Agency HMBS are eligible under the requirements of the National Housing Act and the Ginnie Mae Mortgage-backed Securities Guide, and that the Company will take all actions necessary to ensure the HECM loan’s continued eligibility. The Ginnie Mae HMBS program requires that the Company removes the participation related to any HECM loan that does not meet the requirements of the Ginnie Mae Mortgage-backed Securities Guide. In addition to securitizing HECM loans into Agency HMBS, the Company may sell HECM loans to third parties, and the agreements with such third parties include standard representations and warranties related to such loans, which if breached, may require the Company to repurchase the HECM loan and/or indemnify the purchaser for losses related to such HECM loans. In the case where the Company repurchases the loan, the Company bears any subsequent credit loss on the loan. To the extent that the Company is required to remove a loan from an Agency HMBS, purchase a loan from a third party or indemnify a third party, the potential losses suffered by the Company may be reduced by any recourse the Company has to the originating broker and/or correspondent lender, if applicable, to the extent such entity breached similar or other representations and warranties. Under most circumstances, the Company has the right to require the originating broker/correspondent to repurchase the related loan from the Company and/or indemnify the Company for losses incurred. The Company seeks to manage the risk of repurchase and associated credit exposure through the Company’s underwriting and quality assurance practices.

Share-based Payment Arrangement [Abstract]
Equity Based Compensation	27. Equity Based Compensation Restricted Stock Units Pursuant to the terms of the A&R MLTIP, there are two types of equity based compensation granted to employees, henceforth referred to as Replacement Restricted Stock Units (“Replacement RSUs”) and Earnout Right Restricted Stock Units (“Earnout Right RSUs”). The issuance of the Replacement RSUs and Earnout Right RSUs by pre-transaction the period from April 1, 2021 to December 31, 2021. Therefore, the shares issued to employees under the A&R MLTIP will not result in incremental share ownership in the Company, and the total compensation costs associated with the vesting of the Replacement RSUs and Earnout Right RSUs will be directly allocated to the noncontrolling interest and, with respect to Blocker GP, to FoA in proportion to their sharing percentages of exchanged units. Additionally, pursuant to the terms of the 2021 Omnibus Incentive Plan, the Company granted equity based compensation to the Chief Financial Officer (“CFO”) and five non-employee Non-LTIP (“Non-LTIP Non-LTIP Each type of RSUs is classified as equity and FoA accounts for the RSUs following the fair value method. Each type of RSUs’ fair values is fixed on the grant date and not remeasured unless the award is subsequently modified. Replacement RSUs Pursuant to the terms of the A&R MLTIP executed on October 28, 2020, the Company granted each employee who held Phantom Units in FoA Equity and remained employed as of the Replacement RSU grant date, April 1, 2021, in consideration for the cancellation of a portion of their Phantom Units, Replacement RSUs that will vest into shares of Class A Common Stock. Following the terms of the A&R MLTIP, 25% of the Replacement RSUs vested on the Replacement RSU grant date, and the remaining 75% vest in equal installments on each of the first three anniversaries of the Closing of the Business Combination, subject to each holder’s continued employment. Earnout Right RSUs In addition to the Replacement RSUs, participants in the A&R MLTIP are entitled to receive additional Earnout Right RSUs depending on whether the Company achieves certain market-based conditions. The market-based vesting conditions have been factored into the grant date fair value measurement of the Earnout Right RSUs using a Monte Carlo simulation. The assumptions used in the Monte Carlo simulation model included a volatility rate of 60%, risk free rate of 1.14% and a weighted average expected term of 1.06 years for the first tranche of Earnout Right RSUs and 1.52 years for the second tranche of Earnout Right RSUs. Earnout Right RSUs have the same service-based vesting conditions listed above for the Replacement RSUs along with market-based vesting conditions. The first tranche of Earnout Right RSUs vest upon satisfaction of the service-based vesting conditions and if, at any time during the six years following the Closing, the VWAP of FoA’s Class A Common Stock is greater than or equal to $12.50 for any twenty Trading Days twenty Trading Days Non-LTIP Pursuant to the terms of the 2021 Omnibus Incentive Plan executed on November 18, 2021, the Company granted the CFO 112,149 Non-LTIP non-employee Non-LTIP outlined below.

Any distributions are based on distributions received by equity holders of the Company in excess of the contributed equity capital, plus a designated return on contributed equity capital (the “Hurdle”). The phantom units are accounted for as a profit-sharing arrangement, as they do not represent a substantive form of equity and were not indexed to the price of UFG common units. Equity based compensation expense for the long-term incentive plan totaled $0 million for the period ended December 31, 2020 and $2.9 million for the period ended December 31, 2019. In connection with the Closing of the Business Combination, which occurred on April 1, 2021, the holders of Phantom Units (1,077 units outstanding) received one-time The cash payment of $24.0 million relates to prior services provided solely for the benefit of the Company and not for ongoing services to be provided in the future that would benefit the post-combination entity. Given that the payment was triggered by the distributions made in connection with the successful closing of the Business Combination, the payment of $24.0 million is considered to have been incurred “on the line.” The balance of the Company’s obligation under the Plan was replaced by the issuance of Replacement RSUs and Earnout Right RSUs described above as governed by the A&R MLTIP.

Changes in Contingently Redeemable Noncontrolling Interest	28. Changes in Contingently Redeemable Noncontrolling Interest FoA Equity determined that the Class B interests of FACo Holdings issued B2R meet the definition of CRNCI. Under the FACo Holdings Agreement, the Class B Units may be redeemed upon sale of FACo by FACo Holdings, sale of FAH, or sale of UFG Holdings LLC, which would require FAH to purchase the outstanding Class B Units. FoA Equity determined that the legal provisions in the FACo Holdings Agreement in which there is a noncontrolling interest represent a substantive profit-sharing arrangement, where the allocation to the members differs from the stated ownership percentages. FoA Equity utilized the hypothetical liquidation at book value, or HLBV, method for the allocation of profits and losses each period. Under the HLBV method, the amount of income and loss attributed to the noncontrolling interests in the Consolidated Statements of Operations reflects changes in the amounts each member would hypothetically receive at each Consolidated Statement of Financial Condition date under the liquidation provisions of the FACo Holdings Agreement, assuming the net assets of the FACo Holdings were liquidated at their respective recorded amounts. Allocations of profits and losses in the Consolidated Statements of Operations is determined based on the hypothetical amounts that would be distributed to members after taking into account any capital transactions between FACo Holdings and its members as follows: • Distributions up to Hurdle Amount of $202.0 million (subject to certain adjustments defined in the FACo Holdings Agreement)—100% to Class B Members; • Distributions of the next $150.0 million—95% to Class A Members and 5% to Class B Members, and; • Thereafter—75% to Class A Members and 25% to Class B Members. In connection with the closing of the Business Combination disclosed in Note 4—Acquisitions, FoA caused FAH to exercise its right under the FACo Holdings Agreement to purchase all of the outstanding Class B Units held by B2R for a redemption price of $ million in satisfaction of the applicable Hurdle Amount under the FACo Holdings Agreement.

The effective income tax rate for the Successor period differs from the statutory rate primarily due to income attributable to noncontrolling interests and the impairment of book goodwill recorded during the period. The effective income tax rate for the Predecessor periods differs from the statutory rate primarily due to the business operating as a flowthrough entity which was not subject to U.S. federal and state income taxes. FoA is taxed as a corporation and is subject to corporate federal, state and local taxes on the income allocated to it from FoA Equity, based upon FoA’s economic interest in FoA Equity, as well as any stand-alone income or loss it generates. FoA Equity and its disregarded subsidiaries are treated as a partnership for U.S. federal and most applicable state and local income tax purposes. As a partnership, FoA Equity is not subject to U.S. federal and certain state and local income taxes. FoA Equity’s members, including FoA, are liable for federal, state and local income taxes based on their allocable share of FoA Equity’s pass-through taxable income, which includes income of certain disregarded corporate subsidiaries for tax purposes. FoA Equity wholly owns certain regarded corporate subsidiaries for tax purposes. FoA Equity’s regarded corporate subsidiaries are subject to corporate federal, state and local taxes on income they generate. As such, the consolidated tax provision of FoA addresses corporate taxes that it incurs based on its flow-through income from FoA Equity as well as corporate taxes that are incurred by its regarded subsidiaries. Deferred income taxes reflect the net tax effects of temporary differences between the carrying value of assets and liabilities for financial reporting purposes and the amounts reported for income tax purposes. Significant components of the Company’s deferred income tax assets (liabilities) are as follows (in thousands): December 31, December 31, 2021 2020 Deferred tax assets Loss carryforwards $ 8,765 $ 483 Research and development tax credits 172 — TRA 9,107 — Capital lease amortization — 438 Payroll and employee benefits — 121 Estimate of claim losses — 142 Other — 25 Gross deferred tax assets 18,044 1,209 Valuation allowance (777 ) (160 ) Deferred tax assets, net of valuation allowance 17,267 1,049 Deferred tax liabilities Investment in FoA Equity 35,345 — Depreciation and amortization — 843 Loss reserves — 186 Other 503 307 Gross deferred tax liabilities 35,848 1,336 Net deferred tax liability $ (18,581 ) $ (287 ) The increase in the deferred tax asset balance from the prior year end is primarily a result of the Business Combination. The Company recognized a deferred tax liability (“DTL”) to account for the difference between the Company’s book and tax basis in its investment in FoA Equity. The federal and state net operating loss (“NOL”) carryforwards amount to approximately $34.4 million and $2.9 million at December 31, 2021 and 2020, respectively. It is expected that these NOL’s will not expire. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Net deferred tax liabilities are included in payables and other liabilities in the Consolidated Statements of Financial Condition.

Liquidity And Capital Requirements [Abstract]
Liquidity and Capital Requirements	34. Liquidity and Capital Requirements FAM In addition to the covenant requirements of FAM mentioned in Note 19—Other Financing Lines of Credit, FAM is subject to various regulatory capital requirements administered by HUD as a result of their mortgage origination and servicing activities. HUD governs non-supervised, Failure to meet minimum capital requirements can result in certain mandatory remedial actions and potentially result in additional discretionary remedial actions by regulators that, if undertaken, could: (i) remove FAM’s ability to sell and service loans to or on behalf of the Agencies; and (ii) have a direct material effect on FAM’s financial statements, results of operations and cash flows. In accordance with the regulatory capital guidelines, FAM must meet specific quantitative measures of cash, assets, liabilities, profitability and certain off-balance Among FAM’s various capital requirements related to its outstanding mortgage origination and servicing agreements, the most restrictive of these requires FAM to maintain a minimum adjusted net worth balance as of the end of the most recent fiscal quarter of $154.5 million as of December 31, 2021 (Successor). FAM’s adjusted net worth was $215.0 million as of December 31, 2021 (Successor). FAM is also subject to requirements related to material declines in quarterly and two consecutive quarter tangible net worth. As a result of impacts from the Business Combination, FAM was not in compliance with the second quarter 2021 FNMA lender adjusted tangible net worth quarterly requirement. Additionally, due to the Business Combination, FAM was not in compliance with the ‘two-consecutive quarter’ requirements by FNMA during the second and third quarters of 2021. As of December 31, 2021 (Successor), the Company had obtained all required waivers for these covenant violations. In addition, FAM is required to maintain both fidelity bond and errors and omissions insurance coverage at tiered levels based on the aggregate UPB of the loans serviced by FAM throughout the year. FAM is required to conduct compliance testing at least quarterly to ensure compliance with the foregoing requirements. As of December 31, 2021 (Successor), FAM was in compliance with applicable requirements. FAR As an issuer of HMBS, FAR is required by Ginnie Mae to maintain minimum net worth, liquidity and capitalization levels as well as minimum insurance levels. The net worth required is $5.0 million plus 1% of FAR’s commitment authority from Ginnie Mae. The liquidity requirement is for 20% of FAR’s required net worth to be in the form of cash or cash equivalent assets. FAR is required to maintain a ratio of 6% of net worth to total assets. At December 31, 2021 (Successor), FAR was in compliance with the minimum net worth, liquidity and insurance requirements of Ginnie Mae and had received a waiver for its capital requirement. The minimum tangible net worth required of FAR by Ginnie Mae was $104.4 million at December 31, 2021 (Successor). FAR’s actual net worth calculated based on Ginnie Mae guidance was $521.3 million at December 31, 2021 (Successor). The Company was therefore in compliance with all net worth requirements. In addition, FAR is required to maintain both fidelity bond and errors and omissions insurance coverage at tiered levels based on the aggregate UPB of the loans serviced by FAR throughout the year. FAR is required to conduct compliance testing at least quarterly to ensure compliance with the foregoing requirements. As of December 31, 2021 (Successor), FAR was in compliance with applicable requirements. Incenter Incenter Securities Group LLC (“ISG”), one of the operating subsidiaries of Incenter, operates in a highly regulated environment and is subject to federal and state laws, SEC rules and Financial Industry Regulatory Authority (“FINRA”) rules and guidance. Applicable laws and regulations, among other things, restrict permissible activities and require compliance with a wide range of financial and customer-related protections. The consequences of noncompliance can include substantial monetary and nonmonetary sanctions. In addition, ISG is subject to comprehensive examination by its regulators. These regulators have broad discretion to impose restrictions and limitations on the operations of the Company and to impose sanctions for noncompliance. ISG is subject to the SEC’s Uniform Net Capital Rule (SEC Rule 15c3-1) of minimum net capital. ISG computes net capital under the alternative method. Under this method, the required minimum net capital is equal to $0.3 million. At December 31, 2021 (Successor), ISG met the minimum net capital requirement amounts and was therefore in compliance. Additionally, the ISG claims the exemption provision of SEC Rule 15c3-3(k)(2)(ii). No. 34-70073 240.17a-5 15c2-4. ANTIC, an operating subsidiary of Incenter, has additional capital requirements. The State of Missouri and State of Alabama require domestic title insurance underwriters maintain minimum capital and surplus of $1.6 million and $0.2 million, respectively. Failure to comply with these provisions may result in various actions up to and including surrender of the certificate of authority. Additionally, in October 2019, ANTIC entered into a capital maintenance agreement in conjunction with the approval for the certificate of authority for California. This agreement requires ANTIC to maintain a minimum of $8.0 million in policyholder surplus. If ANTIC falls below this requirement in any given quarter, Incenter must contribute cash, cash equivalents securities or other instruments to bring ANTIC in compliance. The Company’s insurance company subsidiaries met the existing minimum statutory capital and surplus requirements as of December 31, 2021 (Successor). ANTIC is also required to maintain bonds, certificates of deposit and interest bearing accounts in accordance with applicable state regulatory requirements. The total requirement was $3.9 million across all states as of December 31, 2021 (Successor). The Company was in compliance with these requirements as of December 31, 2021 (Successor).

Risks and Uncertainties [Abstract]
Concentrations of Risk	35. Concentrations of Risk The Company’s activities are subject to significant risks and uncertainties, including the ability of management to adequately develop its service lines, acquire adequate customer and revenue bases, and overall market demand for its services. In addition, the Company engages in various trading and brokerage activities in which counterparties primarily include broker-dealers, banks and other financial institutions. In the event counterparties do not fulfill their obligations, the Company may be exposed to risk. The risk of default depends on the creditworthiness of the counterparty or issuer of the instrument. It is the Company’s policy to review, as necessary, the credit standing of each counterparty. Financial instruments, which potentially subject the Company to credit risk, consist of cash and cash equivalents, derivatives, loans held for sale, and loans held for investment. The Company invests its excess cash balances that may exceed federal insured limits with financial institutions evaluated as being creditworthy, primarily in money market accounts which are exposed to minimal interest rate and credit risk. The balances of these accounts are insured by the Federal Deposit Insurance Corporation, subject to certain limitations. Credit risk is reduced by the Company’s underwriting standards, monitoring pledged collateral and other in-house Mortgage loans are sold or financed through one of the following methods: (i) sales or financing securitizations to or pursuant to programs sponsored by FNMA, FHLMC, and Ginnie Mae, or (ii) sales or financing securitizations issued to private investors. The Company sold $20,516.1 million for the Successor period from April 1, 2021 to December 31, 2021, $ 7,696.6 For the Successor period from April 1, 2021 to December 31, 2021, the sale or financing securitizations issued to private investors consisted of 18.6% non-agency non-assignable buy-outs The Company’s sales or financing securitizations issued to private investors for the Predecessor year ended December 31, 2020 consisted of 34.1% non-agency non-agency The Company is partially owned by Libman Family Holdings, LLC, certain investment funds affiliated with Blackstone and other co-investors non-affiliated arm’s-length non-affiliated non-affiliated non-affiliated non-affiliated In July 2017, the Company entered into a $45.0 million mezzanine financing agreement with a non-affiliated agreement was amended in May 2021 from $45.0 million to $25.0 million. As of December 31, 2021 (Successor) and December 31, 2020 (Predecessor) the Company had outstanding borrowings of $21.5 million and $21.5 million, respectively. Residential Mortgages The mortgaged properties securing the residential loans that we service are geographically dispersed throughout the United States. Certain states may experience future weakened economic conditions or greater rates of decline in real estate values than the United States in general. In addition, certain states may change their licensing or other regulatory requirement to make servicing loans in these states cost-prohibitive. The table below provides the percentage of residential mortgage loans serviced by the location in which the home securing the loan is located and is based on the outstanding UPB. “Other” consists of loans in states in which concentration individually represents less than 5% of total remaining UPB.

FAR is subject to approval of, and is heavily regulated by, federal and state regulatory agencies as a mortgage lender, Ginnie Mae issuer, broker and servicer. The secondary market for the FHA insured HECM loans is not assured; to the extent the program requires Congressional appropriations in future years, which are not forthcoming, the program could be jeopardized; and/or, consumer demand could be reduced if FHA actions result in a reduction of initial principal limit available to borrowers. FAR depends on its ability to securitize reverse mortgages, subsequent draws, mortgage insurance premiums and servicing fees, and would be adversely affected if the ability to access the secondary market were to be limited. Concentrations of credit risk associated with reverse mortgage loans are limited due to the large number of customers and their dispersion across many geographic areas. The table below provides the percentage of reverse loans in the Company’s Consolidated Statements of Financial Condition by the location in which the home securing the loan is located and is based on their remaining UPBs. “Other” consists of loans in states in which concentration individually represents less than 5% of total remaining UPB.

Further, Hurricane Maria in 2017 has further stressed the economy and infrastructure in Puerto Rico, resulting in extensive loss of water supplies and electricity. Regulatory agencies require all properties in affected areas to be inspected for “acceptable” condition prior to any transaction occurring with or on behalf of the GSEs or HUD (including foreclosure sale, property conveyance, sale/funding/transfers of originated loans to third parties, etc.). This required inspection may cause delays in foreclosures and settlement of claims. Additionally, in certain circumstances when there are uninsured losses, the Company may be responsible for repairs to the properties if not done by the homeowner. In its determination of fair value amounts for loans that are in disaster impacted areas, the Company has provided for increased expectations of loss severities due to delays in processing claims and uninsured losses. These estimates are based on management’s best estimates of anticipated losses. Actual results may differ from the estimates due to external factors. Commercial Mortgages The economies of states where mortgage properties are concentrated may be adversely affected to a greater degree than the economies of other areas of the country. The table below provides the percentage of commercial loans on the Company’s Consolidated Statements of Financial Condition by the location in which the home securing the loan is located and is based on their remaining UPBs. “Other” consists of loans in states in which concentration individually represents less than 5% of total remaining UPB.

The two major referral partners accounted for approximately 23% and 24% of the Company’s title and closing revenue for the years ended December 31, 2020 and 2019 (Predecessor), respectively. Ratings have always been an important factor in establishing the competitive position of insurance companies. Ratings reflect the opinion of a rating agency with regard to an insurance company’s or insurance holding company’s financial strength, operating performance and ability to meet its obligations to policyholders and are not evaluations directed to investors. The Company’s insurance subsidiary is rated by Demotech and, as of December 31, 2021 (Successor), the rating assigned was A (Exceptional). The Company is subject to continued periodic review by the rating agency and the continued retention of the rating cannot be assured. If the rating is reduced from the current level or the ratings of the Company’s insurance title underwriter are downgraded, the results of operations could be adversely affected.

In December 2021, the Company amended the 2019 Promissory Notes with BTO Urban Holdings and Libman Family Holdings, LLC, which are deemed affiliates of the Company. Amounts under the 2019 Promissory Notes, as amended, may be re-borrowed and repaid from time to time until the related maturity date. The 2021 Promissory Notes accrue interest monthly at a rate o Agricultural Loans In 2019, the Company entered into an Amended and Restated Limited Liability Company Agreement with FarmOp Capital Holdings, LLC (“FarmOps”) in which the Company acquired an equity investment in FarmOps. Subsequent to this agreement, the Company agreed to purchase originated agricultural loans from FarmOps. The Company purchased agricultural loans and had total funded draw amounts of $155.8 million and $182.4 million, respectively, for the Successor period from April 1, 2021 to December 31, 2021, and $83.0 million and $82.1 million, respectively, for the Predecessor period from January 1, 2021 to March 31, 2021. The Predecessor purchased agricultural loans which had total funded draw amounts of $146.2 million for a purchase price of $126.4 million for the year ended December 31, 2020. The Company had promissory notes outstanding with FarmOps of $4.1 million and $0.8 million, including accrued interest, as of December 31, 2021 (Successor) and December 31, 2020 (Predecessor), respectively. In July 2021, upon meeting the contractual exercise condition, the Company exercised its warrant for the purchase of 6,426,015 Series A-2 Cloudvirga In 2017 and 2019, the Company purchased preferred and common stock investments in Cloudvirga, Inc. (“Cloudvirga”). Subsequent to its investment, the Company entered into a software development arrangement in which Cloudvirga agreed to develop software in addition to providing certain technology services for the Company. In May 2021, Cloudvirga merged with an unaffiliated third party, causing the liquidation of all shares held by the Company. As such, the fair value assumptions used to determine the holding value of such preferred equity were updated by the Company and resulted in an impairment of the equity investment of $9.3 million in the Predecessor period from January 1, 2021 to March 31, 2021. As a result of this liquidation of the held shares of Cloudvirga by certain subsidiaries of the Company, the related party relationship was terminated. For the Predecessor period from January 1, 2021 to March 31, 2021, $1.7 million was capitalized related to the development of the software and will be amortized over a 12 month period from the date placed in service. Professional fees paid to Cloudvirga, in exchange for the technology services, were $0.6 million for the Predecessor period from January 1, 2021 to March 31, 2021, $2.4 million for the Predecessor year ended December 31, 2020 and $3.0 million for the Predecessor year ended December 31, 2019. Nonrecourse MSR Financing Liability, at Fair Value In 2020, the Company entered into a nonrevolving facility commitment with various related parties, to sell beneficial interests in the servicing fees generated from its originated or acquired MSRs. Under these agreements, the Company has agreed to sell excess servicing income or pay an amount equal to excess servicing income to third parties, in each case, taking into account cost of servicing and ancillary income related to the identified MSRs in exchange for an upfront payment equal to the purchase price or fair value of the identified MSRs. These transactions are accounted for as financings. As of December 31, 2021 (Successor) and December 31, 2020 (Predecessor), the Company had an outstanding advance of $115.4 million and $14.9 million, respectively, against this commitment for the purchase of MSRs with a fair value of $155.1 million and $14.1 million, respectively. The Company has also entered into Investment Management Agreements with these third parties to serve as the investment manager, in which the Company performs various advisory services to the investors in exchange for a management fees. Management fees amounted to $0.2 million for the Successor period from April 1, 2021 to December 31, 2021 and $0.1 million for the Predecessor period from January 1, 2021 to March 31, 2021. There were no management fees paid for the Predecessor years ended December 31, 2020 and 2019, as the nonrevolving facility commitment did not exist during these periods. Senior Notes Related parties of FoA purchased notes in the high-yield debt offering in November 2020 in an aggregate principal amount of $135.0 million.

Earnings Per Share [Abstract]
Earnings per share	38. Earnings Per Share Basic net income per share is based on the weighted average number of shares of Class A Common Stock issued and outstanding during the Successor period. Diluted net income per share is based on the weighted average number of shares of Class A Common Stock issued and outstanding and the effect of all dilutive common stock equivalents and potentially dilutive share based compensation awards outstanding during the Successor period. For the Predecessor periods, FoA Equity’s capital structure consisted of a single class of outstanding membership units which are held by one member, UFG. Therefore, the Company has omitted earnings per unit for the Predecessor periods presented due to the limited number of LLC unit holders. The following tables reconcile the numerators and denominators used in the computations of both basic and diluted earnings per share for the Successor periods (in thousands, except share data and per share amounts): April 1, 2021 to December 31, 2021 Successor Basic net income (loss) per share: Numerator Net loss $ (1,301,002 ) Less: loss attributable to noncontrolling interests (1) (929,202 ) Net loss attributable to holders of Class A Common Stock—basic $ (371,800 ) Denominator Weighted average shares of Class A Common Stock outstanding—basic 59,849,638 Basic net loss per share $ (6.21 ) (1) The Class A LLC Units of FoA Equity, held by the Continuing Unitholders, which comprise the noncontrolling interest in the Company, represents a participating security. Therefore, the numerator was adjusted to reduce net income by the amount of net income attributable to noncontrolling interests. Additionally, the Class B Common Stock does not participate in earnings or losses of the Company and therefore is not a participating security. The Class B Common Stock has not been included in either the basic or diluted net income per share calculations. Loss attributable to noncontrolling interest includes special allocations of recognized expense related to the A&R MLTIP. See Note 27—Equity Based Compensation for additional details.

Sponsor Earnout [Abstract]
Sponsor Earnout	39. Sponsor Earnout Contemporaneously with the execution of the Transaction Agreement, the initial shareholders entered into an amendment and restatement of the existing Sponsor Agreement (as amended and restated, the “Sponsor Agreement”) with FoA, Replay and FoA Equity, pursuant to which, in connection with the Closing of the Business Combination, among other things, (i) immediately prior to the Domestication (as defined below), the 7,750,000 of private placement warrants (the “Private Warrants”) owned by the Sponsor were exchanged for 775,000 ordinary shares which then converted into shares of Class A Common Stock and (ii) excluding the 90,000 Founder Shares held by Replay’s independent directors (unless transferred to any other initial shareholder or permitted transferee thereof) that were converted into shares of Class A Common Sock and immediately vested, 40% of the Founder Shares shares held by the Sponsor (2,839,000 shares) were converted into vested Class A Common Stock and became wholly owned by the Sponsor immediately prior to the Closing of the Business Combination and 60% of the Founder Shares held by the Sponsor (4,258,500 shares) were converted into unvested shares of Class A Common Stock and are subject to vesting and forfeiture in accordance with certain terms and conditions, as laid out below. If at any time during the six years following the Closing, the VWAP of FoA’s Class A Common Stock is greater than or equal to $12.50 for any twenty (20) Trading Days within a period of thirty (30) consecutive Trading Days (“First Sponsor Earnout Achievement Date”) then 35% of the total Founder Shares owned by each Sponsor Person shall vest. If the First Sponsor Earnout Achievement Date has not occurred within six years of the Closing Date the Founder Shares that were eligible to vest shall not vest and shall be forfeited. If at any time during the six years following the Closing, the VWAP of FoA’s Class A Common Stock is greater than or equal to $15.00 for any twenty (20) Trading Days within a period of thirty (30) consecutive Trading Days (“Second Sponsor Earnout Achievement Date”) then 25% of the total Founder Shares owned by each Sponsor Person shall vest. If the Second Sponsor Earnout Achievement Date has not occurred within six years of the Closing Date the Founder Shares that were eligible to vest shall not vest and shall be forfeited. Given that the Sponsor Agreement was issued to the acquirers of FoA Equity, and not to the sellers of FoA Equity, the Pre-Closing for separately from the other provisions of the Transaction Agreement. The Company classified the Sponsor Agreement as an equity transaction. Given the equity classification, the Sponsor shares were measured at a fair value of $38.1 million upon the consummation of the Transaction Agreement, the date of issuance, and will not be subsequently remeasured. Additionally, the settlement of the Sponsor Agreement will be accounted for within equity, if and when the First or Second Earnout Achievement Date occurs. The fair value was determined by using a Monte Carlo simulation to forecast the future daily price per share of Class A Common Stock over a six-year

Accounting Policies [Line Items]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements comprise the financial statements of FoA and its controlled subsidiaries for the Successor period from April 1, 2021 to December 31, 2021 and the financial statements of FoA Equity and its controlled subsidiaries for the Predecessor periods from January 1, 2021 to March 31, 2021 and for the years ended December 31, 2020 and 2019. The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for financial statements and pursuant to the accounting and disclosure rules and regulations of the SEC. The Consolidated Statement of Financial Condition as of December 31, 2020 has been derived from the audited consolidated financial statements of the Predecessor as of and for the years ended December 31, 2020 and 2019. In the opinion of management, such financial information reflects all normal and recurring adjustments necessary for a fair presentation of the financial position and the results of operations for such periods in accordance with GAAP. On October 12, 2020, the Company, Replay and FoA Equity entered into the Transaction Agreement pursuant to which Replay agreed to combine with FoA Equity in a series of transactions that resulted in the formation of FoA as a publicly traded company on the NYSE, and FoA controlling FoA Equity in an Business Combination. At the Closing on April 1, 2021 (the “Closing Date”), Replay domesticated into a Delaware corporation and FoA was formed. See Note 4—Acquisitions for additional information. The consolidated financial statements include the accounts of the Predecessor, prior to the Business Combination, which was determined to be FoA Equity, a limited liability company that was formed in July 2020. Prior to the Business Combination, FoA Equity was a wholly owned subsidiary of UFG. FoA Equity owned all of the outstanding equity interests or had a controlling financial interest in FOAF. FAH and Incenter LLC were wholly owned subsidiaries of FOAF, and are included in the consolidated financial statements along with their consolidated operating lending subsidiaries and operating service subsidiaries. See Note 1—Organization and Description of Business for additional information. The significant accounting policies described below, together with the other notes that follow, are an integral part of the consolidated financial statements.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates and assumptions due to factors such as changes in the economy, interest rates, secondary market pricing, prepayment assumptions, home prices or discrete events affecting specific borrowers, and such differences could be material.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company, its controlled subsidiaries and certain variable interest entities (“VIEs”) where the Company is the primary beneficiary. The Company is deemed to be the primary beneficiary of a VIE when it has both (1) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance and (2) exposure to benefits and/or losses that could potentially be significant to the entity. Assets and liabilities of VIEs and their respective results of operations are consolidated from the date that the Company became the primary beneficiary through the date that the Company ceases to be the primary beneficiary. FoA Equity consolidates the accounts of Finance of America Commercial Holdings LLC (“FACo Holdings”), which is a direct subsidiary of FAH and an indirect parent company of FACo. Through the date of the Business Combination, the noncontrolling interests of FACo Holdings met the definition of contingently redeemable financial instruments for which the ability to redeem was outside the control of the consolidating entity. The Con
Business Combinations	Business Combinations The Company applies the acquisition method to all transactions and other events in which the entity obtains control over one or more other businesses. Assets acquired and liabilities assumed are measured at fair value as of the acquisition date. Liabilities related to contingent consideration are recognized at the acquisition date and re-measured Under ASC 805, there is an option to apply push-down accounting, which establishes a new basis for the assets and liabilities of the acquired company based on a “push-down” of the acquirer’s stepped-up
VIEs	VIEs The Company has been the transferor in connection with securitizations or asset-backed financing arrangements with special purpose entities (“SPE”), in which the Company has continuing involvement with the underlying transferred financial assets. The Company’s continuing involvement includes acting as servicer for the mortgage loans transferred and retaining beneficial interests in the SPE to which the assets were transferred. The Company evaluates its interests in each SPE for classification as a VIE in accordance with ASC 810-10 Consolidation The beneficial interests held consist of residual securities that were retained at the time of securitization. These beneficial interests may obligate the Company to absorb losses of the VIE that could potentially be significant to the VIE, or affords the Company the right to receive benefits from the VIE that could potentially be significant. In addition, when the Company acts as servicer of the transferred assets, the Company retains the power to direct the activities of the VIE that most significantly impact the economic performance of the VIE. When it is determined that the Company has both the power to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE, the assets and liabilities of these VIEs are included in the consolidated financial statements of the Company. The Company reassesses its evaluation of an entity as a VIE upon the occurrence of certain reconsideration events as the primary beneficiary determination may change over time as interest in the VIE changes. The Company elected the fair value option provided for by ASC 825-10, Financial Instruments-Overall See Note 3—Variable Interest Entities and Securitizations for further discussion of VIEs in which the Company is deemed to be the primary beneficiary.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. These investments are with high quality financial, governmental or corporate institutions and potentially subject the Company to concentrations of credit risk. December 31, December 31, Successor Predecessor Cash and cash equivalents $ 141,238 $ 233,101 Restricted cash 322,403 306,262 Total cash, cash equivalents, and restricted cash in statement of cash flows $ 463,641 $ 539,363
Restricted Cash	Restricted Cash Restricted cash includes amounts specifically designated to repay debt and provide over-collateralization within warehouse facilities and securitized nonrecourse debt obligations, custodial accounts related to the Company’s portfolio of mortgage loans serviced for investors, and funds deposited from prospective borrowers to cover out-of-pocket
Loans Held for Investment, Subject to HMBS Related Obligations, at Fair Value	Loans Held for Investment, Subject to HMBS Related Obligations, at Fair Value The Company elected the fair value option provided for by ASC 825-10, Financial Instruments-Overall A maturity event will cause the loan to become due and payable. Maturity events include: borrower has passed away and the property is not the principal residence of at least one surviving borrower; borrower has sold or conveyed title of the property to a third party; the property is no longer the principal residence of at least one borrower for reasons other than death; the borrower does not maintain the property as principal residence for a period exceeding 12 months; the borrower fails to pay property taxes and/or insurance and all attempts to rectify the situation have been exhausted; and the property is in disrepair and the borrower has refused or is unable to repair the property. Once a loan has become due and payable, unsecuritized borrower advances cannot be placed into a Ginnie Mae HMBS. Generally, the Company recovers such advances (referred to as unpoolable tails) from borrowers, from proceeds of liquidation of collateral or ultimate disposition of the loan, including conveyance of claims to FHA. If the loan is not paid within six months of the maturity event, the Company may proceed with foreclosure on the property. A loan may be satisfied by borrower repayment, sales or appraisal-based claim submissions to HUD and/or foreclosure sale proceeds. If the Company sells the property within six months, it may file a sales-based claim with HUD to recover any shortfall between the sales price of the property and the outstanding loan balance. If the property is not sold within six months, the Company may file an appraisal-based claim with HUD to recover any shortfall between the appraised value and the outstanding loan balance. Once the appraisal based claim is paid by HUD, any subsequent expenses or loss in the property’s value exposes the Company to additional losses that may not be eligible to be recouped through the filing of an additional HUD claim. The Company has determined that HECM loans transferred under the current Ginnie Mae HMBS securitization program do not meet the requirements for sale accounting and are not derecognized upon date of transfer. The Ginnie Mae HMBS securitization program includes certain terms that do not meet the participating interest requirements and require or provide an option for the Company to reacquire the loans prior to maturity. Due to these terms, the transfer of the loans does not meet the requirements of sale accounting. As a result, the Company accounts for HECM loans transferred into HMBS securitizations as secured borrowings and continues to recognize the loans as held for investment, subject to HMBS related obligations, along with the corresponding liability for the HMBS related obligations. No gains or losses are recognized on these transfers of HECM loans into HMBS securitizations. Loans are considered nonperforming upon events such as, but not limited to, the death of the mortgagor, the mortgagor no longer occupying the property as their principal residence, or the property taxes or insurance not being paid. In addition to having to fund these repurchases, the Company also typically earns a lower interest rate and incurs certain non-reimbursable Loans held for investment, subject to HMBS related obligations, also include claims receivable that have been submitted to HUD awaiting reimbursement. These amounts are recorded net of amounts the Company does not expect to recover through outstanding claims. The yield recognized on loans held for investment, subject to HMBS related obligations, and changes in estimated fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The yield recognized includes the recognition of interest income based on the stated interest rates of the loans that is expected to be collected through conveyance of loans to FHA, repayment by borrower or through disposition of real estate upon foreclosure. Loan origination fees represent an up-front Certain HECM and jumbo reverse mortgage loans originated or acquired by the Company include broker compensation or correspondent fees. These premiums are remitted to the mortgage broker or correspondent lender who acted as the intermediary for the reverse mortgage. Broker compensation and correspondent fees are recorded on a net basis in net fair value gains on loans and related obligations in the Consolidated Statements of Operations and therefore not separately presented. See Note 5—Fair Value for further discussion of valuation of loans held for investment, subject to HMBS related obligations.
Loans Held for Investment, Subject to Nonrecourse Debt, at Fair Value	Loans Held for Investment, Subject to Nonrecourse Debt, at Fair Value Loans held for investment, subject to nonrecourse debt, at fair value, are loans that were securitized and serve as collateral for the issued nonrecourse debt, including HECM Buyouts, agricultural securitized loans, fix & flip securitized loans, and non FHA-insured (“non-agency The yield recognized on loans held for investment, subject to nonrecourse debt, at fair value and changes in estimated fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The yield recognized includes the contractual interest income that is expected to be collected based on the stated interest rates of the loans.
Loans Held for Investment, at Fair Value	Loans Held for Investment, at Fair Value Loans held for investment, at fair value, consists of certain reverse mortgage and commercial mortgage loans that the Company intends to hold to maturity. The Company has elected the fair value option for all loans held for investment and determines the fair value, on a recurring basis, based on DCF models. These valuations require the use of judgment by the Company and changes in assumptions can have a significant impact on the determination of the loan’s fair value. The difference between the cost basis of newly originated or acquired loans and their estimated fair value is recognized in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. See Note 5—Fair Value for further discussion of valuation of loans held for investment. The yield recognized on loans held for investment and changes in estimated fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The yield recognized includes the contractual interest income that is expected to be collected based on the stated interest rates of the loans. Reverse Mortgage Loans Reverse mortgage loans held for investment consists of originated or purchased HECM and non-agency HECM loans and tails that have not yet been securitized into HMBS consist primarily of newly-issued HECMs that the Company has either originated or purchased, subsequent borrower draws and amounts paid by the Company on the borrower’s behalf for MIP that have not yet been transferred to a Ginnie Mae securitization. As a jumbo reverse mortgage, non-agency Non-agency The Company, as an issuer of HMBS, is required to repurchase reverse loans out of the Ginnie Mae securitization pools once the outstanding principal balance of the related HECM is equal to or greater than 98% of the Maximum Claim Amount (“MCA”) (referred to as HECM Buyouts). Performing repurchased loans are conveyed to HUD and payment is received from HUD typically within 75 days of repurchase. Nonperforming repurchased loans are generally liquidated through foreclosure, subsequent sale of the real estate owned, and claim submissions to HUD. Loans are considered nonperforming upon events such as, but not limited to, the death of the mortgagor, the mortgagor no longer occupying the property as their principal residence, or the property taxes or insurance not being paid. In addition to having to fund these repurchases, the Company also typically earns a lower interest rate and incurs certain non-reimbursable Reverse mortgage loans also include claims receivable that have been submitted to HUD awaiting reimbursement. These amounts are recorded net of amounts the Company does not expect to recover through outstanding claims. Certain HECM and jumbo reverse mortgage loans originated or acquired by the Company include broker compensation or correspondent fees. These premiums are remitted to the mortgage broker or correspondent lender who acted as the intermediary for the reverse mortgage. Broker compensation and correspondent fees are recorded on a net basis in net fair value gains on loans and related obligations and therefore are not separately presented in the Consolidated Statements of Operations. Commercial Mortgage Loans Commercial mortgage loans held for investment primarily consist of short-term loans for real estate investors and agricultural loans for farmers.
Loans Held for Sale, at Fair Value	Loans Held for Sale, at Fair Value Loans held for sale, at fair value, represent mortgage loans originated by the Company and held until sold to secondary market investors. The Company primarily originates conventional GSEs, government insured (FHA), and government guaranteed (Department of Veteran Affairs) residential mortgage loans (collectively “residential mortgage loans held for sale”), and commercial mortgage loans to owners and investors of single and multi-family residential rental properties (“commercial loans held for sale”). The Company elected the fair value option provided for by ASC 825-10, Financial Instruments-Overall Loans held for sale are measured at fair value at the time of origination and on a recurring basis thereafter. Gains and losses on loans held for sale are recorded in gain on sale and other income from loans held for sale, net, in the Consolidated Statements of Operations. The yield recognized includes the contractual interest income that is expected to be collected based on the stated interest rates of the loans. In connection with the Company’s election to measure originated loans held for sale at fair value, any fees recognized in relation to originated loans are recognized as they are received and are included in fee income in the Consolidated Statements of Operations. Direct loan origination costs and fees are expensed when incurred and are included in general and administrative expenses in the Consolidated Statements of Operations. Residential Mortgage and Home Improvement Loans Held for Sale Residential mortgage and home improvement loans held for sale are typically warehoused for a period after origination or purchase before sale into the secondary market. Servicing rights are either released upon sale of mortgage loans in the secondary market or retained by the Company. The yield on residential mortgage loans held for sale is recorded in interest income and changes in fair value are recorded in gain on sale and other income from loans held for sale, net, in the Consolidated Statements of Operations. Commercial Loans Held for Sale The Company estimates fair value by evaluating a variety of market indicators, including recent sales of similar product types and outstanding commitments, calculated on an aggregate basis. The yield recognized on commercial loans held for sale and changes in estimated fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. In connection with the Company’s election to measure loans held for sale at fair value, the Company is not permitted to defer the loan origination fees, net of direct loan origination costs associated with these loans.
Mortgage Servicing Rights, at Fair Value	Mortgage Servicing Rights, at Fair Value Mortgage servicing rights (“MSRs”) represent contractual rights to perform specific administrative functions for the underlying loans including specified mortgage servicing activities, which consist of collecting loan payments, remitting principal and interest payments to investors, managing escrow funds for the payment of mortgage-related expenses such as taxes and insurance, and otherwise administrating the mortgage loan servicing portfolio. MSRs are created through the sale of an originated mortgage loan or purchased from third parties. The unpaid principal balance (“UPB”) of the loans underlying the MSRs is not included i The Company follows the fair value measurement method to record the value of MSRs in accordance with ASC 860, Transfers and Servicing The fair value of the MSRs is based upon the present value of the expected future net cash flows related to servicing these loans. For MSRs that the Company has current commitments to sell to third parties, the fair value is based on the outstanding commitment price. The Company receives a base servicing fee based on the remaining outstanding principal balances of the loans, which are collected from borrowers on a monthly basis. The Company determines the fair value of the MSRs by the use of a DCF model that incorporates prepayment speeds, delinquencies, discount rate, ancillary revenues and other assumptions (including costs to service) that management believes are consistent with the assumptions other similar market participants use in valuing the MSRs. The primary risk associated with MSRs is the potential reduction in fair value as a result of higher than anticipated prepayments due to loan refinancing prompted, in part, by declining interest rates or government intervention. Conversely, these assets generally increase in value in a rising interest rate environment to the extent that prepayments are slower than anticipated. At times, the Company may utilize derivatives as economic hedges to offset changes in the fair value of the MSRs resulting from the actual or anticipated changes in prepayments stemming from changing interest rate environments. There is also a risk of valuation decline due to higher than expected increases in default rates, which the Company does not believe can be effectively managed using derivatives.
Debt Securities	Debt Securities Debt securities consists of U.S. government securities, securities backed by collateral pools of non-agency reverse mortgages that are not insured by the FHA, and other debt securities. The Company accounts for debt securities in accordance with ASC 320 , Investments-Debt and Equity Securities (“ASC 320 ”). The Company determines the classification of securities at purchase. The Company classifies debt securities into held-to-maturity, trading, or available-for-sale categories. Debt securities that management has the ability and intent to hold to maturity are classified as held-to-maturity and carried at amortized cost adjusted for amortization of premiums and accretion of discounts amortized over the contractual term of the securities in a method that approximates the interest method. The Company has elected to account for certain debt securities at fair value under the fair value option provisions included in ASC 825, Financial Instruments instrument-by-instrument
Derivatives and Hedging Activities	Derivatives and Hedging Activities The Company’s principal market exposure is to interest rate risk, specifically long-term U.S. Treasury and mortgage interest rates due to their impact on the fair value of mortgage loans and related commitments. The Company uses derivative instruments as part of its overall strategy to manage its exposure to market and price risks primarily associated with fluctuations in interest rates. As a matter of policy, the Company does not use derivatives for speculative purposes. Interest Rate Lock Commitments Interest rate lock commitments (“IRLCs”) represent an agreement to extend credit to a mortgage loan applicant, whereby the interest rate on the loan is set prior to funding. The IRLC binds the Company (subject to the loan approval process) to lend funds to a potential borrower at the specified rate, regardless of whether interest rates have changed between the commitment date and the loan funding date. As such, outstanding IRLCs are subject to interest rate risk and related price risk during the period from the date of issuance through the date of loan funding, cancellation or expiration. The Company uses mandatory and best efforts commitments to substantially mitigate these risks. Loan commitments generally range between 30 and 90 days; however, the borrower is not obligated to obtain the loan. The Company is subject to fallout risk related to IRLCs, which is realized if approved borrowers choose not to close on the loans within the terms of the IRLCs. Historical commitment-to-closing IRLCs that relate to the origination of a mortgage that will be held for sale upon funding are considered derivative instruments under the derivatives and hedging accounting guidance ASC 815, Derivatives and Hedging The fair value of the Company’s IRLCs is based upon the estimated fair value of the underlying mortgage loan, adjusted for (i) estimated costs to complete and originate the loan and (ii) the estimated percentage of IRLCs that will result in a closed mortgage loan. The valuation of the Company’s IRLCs are based on prices of MBS in the market place and the value of the related mortgage servicing. Forward Loan Sale Commitments The Company is subject to interest rate and price risk on its loans held for sale, at fair value, and IRLCs from the date the IRLC is made until the date the loan is sold. Mandatory commitments which fix the forward sales price that will be realized in the secondary market are used to substantially mitigate the interest rate and price risk to the Company. The Company carefully evaluates all loan sale agreements to determine whether they meet the definition of a derivative under the derivatives and hedging accounting guidance under ASC 815. To mitigate the price risk the Company is exposed to on its outstanding loan commitments, the Company uses “mandatory delivery” forward loan sale commitments to manage the risk of potential interest rate movements and their impact on the value of the underlying mortgage loans. Mandatory delivery contracts that meet the definition of a derivative are accounted for as derivative instruments. Accordingly, forward loan sale commitments are recognized at fair value on the Consolidated Statements of Financial Condition in derivative assets or payables and other liabilities with changes in their fair values recorded in gain on sale and other income from loans held for sale, net, in the Consolidated Statements of Operations. The fair value is determined on a recurring basis based on forward prices with dealers in such securities or internally-developed or third party models utilizing observable market inputs. To Be Announced Securities To Be Announced Securities (“TBAs”) are “forward delivery” securities considered derivative instruments under derivatives and hedging accounting guidance ASC 815. The Company uses TBAs to protect against the price risk inherent in derivative loan commitments. TBAs are valued based on forward dealer marks from the Company’s approved counterparties. The Company utilizes internal and third party market pricing services which compile current prices for instruments from market sources, and those prices represent the current executable price. TBAs are recorded at fair value in the Consolidated Statements of Financial Condition in derivative assets and payables and other liabilities, with changes in fair value recorded in gain on sale and other income from loans held for sale, net, and net fair value gains on loans and related obligations in the Consolidated Statements of Operations. Best Efforts Commitments The Company uses best efforts commitments with various investors to mitigate the risk associated with loans held for sale, at fair value , Forward MBS Commitments Periodically, the Company uses forward MBS commitments to hedge changes in the value of MSRs. MSRs are subject to substantial interest rate risk as the mortgage loans underlying the servicing rights permit the borrowers to prepay the loans. The Company may at times enter into economic hedges, which do not qualify as hedges for accounting purposes, including forward contracts to minimize the effects of loss in value of these MSRs associated with increased prepayment activity that generally results from declining interest rates. Forward MBS commitments are recorded at fair value in the Consolidated Statements of Financial Condition in derivative assets and payables and other liabilities, with changes in fair value recorded in gain on sale and other income from loans held for sale, net, in the Consolidated Statements of Operations. The Company treats forward HMBS purchase and sale commitments that have not settled as derivative instruments. Any changes in fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The fair value is determined on a recurring basis based on forward prices with dealers in such securities or internally-developed or third party models utilizing observable market inputs. These forward commitments will be fulfilled with loans not yet securitized and new reverse mortgage loan originations and purchases. Interest Rate Swaps, Interest Rate Swap Futures and Futures Contracts The Company also enters into interest rate swaps, interest rate swap futures and futures contracts to offset changes in the value of its non-agency
Fixed Assets and Leasehold Improvements, Net	Fixed Assets and Leasehold Improvements, Net Fixed assets are depreciated on a straight-line basis over their estimated useful lives. Leasehold improvements are amortized on a straight-line basis over the shorter of the term of the related office lease or the expected useful life of the assets. The Company capitalizes certain costs associated with the acquisition of internal-use
Goodwill	Goodwill Goodwill is the excess of the purchase price over the fair value of the net assets acquired. Goodwill is not amortized, but is reviewed for impairment annually as of October 1 and monitored for interim triggering events on an ongoing basis. If triggering events occur, which indicate goodwill might be impaired between annual tests, goodwill will be tested when such events occur. In making this assessment, the Company considers a number of factors including, but not limited to, operating results, business plans, economic projections, share price and anticipated future cash flows. There are inherent uncertainties related to these factors and management’s judgment in applying them to the analysis of goodwill impairment. Changes in economic and operating conditions could result in goodwill impairment in future periods. In testing goodwill for impairment, the Company performs a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit is less than its carrying value including goodwill. If the qualitative assessment determines that it is more likely than not that the fair value of the reporting unit is less than its carrying value including goodwill, the Company will compare the fair value of that reporting unit with its carrying value including goodwill. If the carrying value of a reporting unit exceeds its fair value, goodwill is considered impaired with the impairment loss equal to the amount by which the carrying value of the goodwill exceeds the implied fair value of that goodwill. Impairment related to goodwill is recorded in impairment of goodwill and intangible assets on the Consolidated Statements of Operations.
Intangible Assets, Net	Intangible Assets, Net Intangible assets, net, primarily consist of trade names and broker/customer relationships acquired through various acquisitions and the Business Combination and recorded at their estimated fair value on the date of
Leases	Leases The Company evaluates all leases at inception under ASC 842 and classifies the lease as either an operating or a finance lease. The Company currently only has operating leases. Operating lease ROU assets represent the Company’s right to use an underlying asset during the lease term. ROU assets are further adjusted for lease incentives. Operating lease expense is recognized on a straight-line basis over the lease term and is recorded in general and administrative expenses in the Consolidated Statements of Operations. The Company recognizes variable lease payments associated with the Company’s leases when the variability is resolved. Variable lease payments are recorded in Occupancy, equipment rentals and other office related expenses in the Consolidated Statements of Operations along with expenses arising from fixed lease payments. See Note 21 - Leases for more information. Operating lease liabilities represent the Company’s obligation to make lease payments arising from the terms of the lease. The lease liabilities are initially recognized based on the present value of the remaining lease payments using a discount rate that represents the Company’s incremental borrowing rate as of the lease commencement date. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available as of the lease commencement date in determining the present value of the lease payments. This incremental borrowing rate is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment and given similar credit risk. The lease term for all of the Company’s leases includes the noncancellable period of the lease plus any additional periods covered by the option to extend (or not to terminate) the lease. The Company includes these options in the lease term when it is reasonably certain of exercising them. ASC 842 provides for policy elections related to leases with a term of 12 months or less and separation of lease components from non-lease components. The Company elected not to recognize lease assets and lease liabilities for leases with a term of 12 months or less and not to separate lease components from non-lease components.
Other Assets, Net	Other Assets, Net Other assets, net, consist of right-of-use Receivables, Net of Allowance Receivables, net of allowance, are represented by amounts due from investors and other parties and are stated at the amounts management expects to collect. If the Company expects to collect less than 100% of the recorded receivable balances, an allowance for doubtful accounts is recorded based on the current expected credit loss (“CECL”) methodology which includes a combination of historical experience, aging analysis, information on specific balances and reasonable and supportable forecasts. Government Guaranteed Receivables, Net The Company accounts for foreclosed mortgage loans guaranteed by the government as a separate receivable. These amounts are carried at the net amounts the Company expects to receive from the liquidation of the underlying property and any expected claim proceeds from HUD for shortfall on liquidation proceeds in other assets, net, in the Consolidated Statements of Financial Condition. Outstanding HUD claims associated with HECM loans that are collateral for issued and outstanding HMBS may be retained inside the HMBS while the associated HECM loan remains insured by HUD or a HUD claim is outstanding and the HECM loan has not yet reached % of the loan’s MCA. Subsequent to reaching % of the MCA, the Company must purchase the loan out of the HMBS. Servicer Advances, Net of Allowance The Company is required under certain servicing contracts to ensure that property taxes, insurance premiums, foreclosure costs and various other items are paid in order to preserve the assets being serviced. Generally, the Company recovers such advances from borrowers for reinstated or performing loans, proceeds of liquidation of collateral or ultimate disposition of the loan, credit owners or loan insurers. Investments, at Fair Value The Company invests in the equity of other companies in the form of common stock, preferred stock or other in-substance Investments—Equity Method and Joint Ventures The Company has elected to account for certain of its investments at fair value under the fair value option provisions included in FASB ASC 825, Financial Instruments Equity securities with a readily determinable fair value are required to be measured at fair value, with changes in fair value recognized through net income. Equity securities without readily determinable fair value are carried at cost, less any impairment plus or minus changes resulting from observable price changes for identical or similar investments. Loans Subject to Repurchase from Ginnie Mae For certain loans that the Company has pooled and securitized with Ginnie Mae, the Company as the issuer has the unilateral right to repurchase, with Ginnie Mae’s prior authorization, any individual loan in a Ginnie Mae securitization pool if that loan meets certain criteria, including being delinquent greater than 90 days. Once the Company has the unilateral right to repurchase a delinquent loan, the Company has effectively regained control over the loan and, under GAAP, must re-recognize Receivable from Clearing Organization The Company clears all of its proprietary and all of its customer transactions from its broker-dealer transactions through another broker-dealer on a fully disclosed basis. Securities transactions are recorded on the trade date as if they had settled. The related amounts receivable and payable for unsettled securities transactions, along with contractual deposits are recorded in other assets, net, on the Consolidated Statements of Financial Condition.
HMBS Related Obligations, at Fair Value	HMBS Related Obligations, at Fair Value HMBS related obligations, at fair value, represent the secured borrowing associated with the Company’s securitization of HECM loans where the securitization does not meet the criteria for sale accounting treatment. This liability includes the Company’s obligation to repay the secured borrowing from the FHA insured HECM cash flows and the obligations as issuer and servicer of the HECM loans and HMBS. As an issuer of HMBS, the Company is obligated to service the HECM loan and associated HMBS, which includes funding the repurchase of the HECM loans or pass through of cash due to the holder of the beneficial interests in the Ginnie Mae HMBS upon maturity events and certain funding obligations related to monthly guarantee fees, mortgage insurance proceeds and partial month interest. As an issuer, the Company is required to repurchase reverse loans out of the Ginnie Mae securitization pools once the outstanding principal balance of the related HECM is equal to or greater than 98% of the MCA. The Company is also required to pay off the outstanding remaining principal balance of secured borrowings if certain triggering events are reached prior to the 98% of MCA limit, such as death of borrower and completion of foreclosure. Performing repurchased loans are conveyed to HUD and payment is received from HUD typically within 75 days of repurchase. Nonperforming repurchased loans are generally liquidated through foreclosure, subsequent sale of real estate owned and claim submissions to HUD. Loans are considered nonperforming upon events such as, but not limited to, the death of the mortgagor, the mortgagor no longer occupying the property as their principal residence, or the property taxes or insurance not being paid. The Company relies upon its secured financing facilities (see Note 19—Other Financing Lines of Credit) and operating cash flows, to the extent necessary, to repurchase loans. The timing and amount of the Company’s obligation to repurchase HECMs is uncertain as repurchase is predicated on certain factors such as whether or not a borrower event of default occurs prior to the HECM reaching the mandatory repurchase threshold under which the Company is obligated to repurchase the loan. Performing repurchased loans are conveyed to HUD and nonperforming repurchased loans are generally liquidated in accordance with program requirements. In addition to having to fund repurchases, the Company may sustain losses during the process of liquidating the loans. The issuer is also required to fund guarantee fees to Ginnie Mae, MIP to the FHA and is obligated to fund partial month interest resulting from shortfalls in interest received from borrower payoffs to the holders of the HMBS beneficial interests. Estimated cash flows associated with these obligations are included in the HMBS related obligations, at fair value, in the Consolidated Statements of Financial Condition. The Company has elected to record the HMBS related obligations at fair value. The estimated fair value is generally determined by discounting expected principal, interest and other servicing or issuer obligation cash flows using an estimated market discount rate that management believes a market participant would consider in determining fair value. See Note 5—Fair Value for further discussion of valuation of HMBS related obligations. The yield on HMBS related obligations along with any changes in fair value are recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The yield on the HMBS related obligations includes recognition of contractual interest expense based on the stated interest rates of the HMBS beneficial interests.
Nonrecourse Debt, at Fair Value	Nonrecourse Debt, at Fair Value Nonrecourse debt, at fair value, is debt of consolidated VIE securitization trusts or non consolidated funds that provide nonrecourse The Company has elected to measure the outstanding nonrecourse debt at fair value in the Consolidated Statements of Financial Condition with all changes in fair value recorded to net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The yield on nonrecourse debt and any change in fair value are also recorded in net fair value gains on loans and related obligations in the Consolidated Statements of Operations. The yield recognized includes the contractual interest expense based on the stated interest rates of the debt and amortization of any discount at which the related bonds were issued. Reverse Mortgage Loans The Company securitizes certain of its interests in HECM Buyouts and non-agency one-to-four-family Commercial Mortgage Loans The Company issues nonrecourse debt securities secured by mortgage loans made to real estate investors. The transactions provide debt security holders the ability to invest in a pool of performing loans secured by investment real estate. The Company issues nonrecourse debt securities secured by agricultural loans made to investors. The transactions provide the Company with access to liquidity for the mortgage loans and ongoing management fees. Nonrecourse MSR Financing Liability The Company has agreements with third parties and has sold beneficial interests in the servicing fees generated from its originated or acquired MSRs. Under these agreements, the Company has agreed to sell to the third parties the right to receive all excess servicing and ancillary fees related to the identified MSRs in exchange for an upfront payment equal to the entire purchase price of the acquired or originated MSRs. The Company elected to measure the outstanding financings related to the nonrecourse MSR financing liability at fair value as permitted under ASC 825 , Financial Instruments
Other Financing Lines of Credit	Other Financing Lines of Credit Other financing lines of credit principally consists of variable-rate, asset-backed facilities, primarily warehouse lines of credit, to support the origination of mortgage loans and operations of the Company, which provide creditors a collateralized interest in specific mortgage loans and other Company assets that meet the eligibility requirements under the terms of the facility. The source of repayment of the facilities is typically from the sale or securitization of the underlying loans into the secondary mortgage market. The Company evaluates its capacity needs for warehouse facilities and adjusts the amount of available capacity under these facilities in response to the current mortgage environment and origination needs. Interest expense from these financings is recorded in net interest expense in the Consolidated Statements of Operations. Costs incurred in connection with obtaining financing lines of credit are capitalized to other assets, net, within the Consolidated Statements of Financial Condition and amortized over the term of the related financing as interest expense within the Consolidated Statements of Operations.
Payables and Other Liabilities	Payables and Other Liabilities Payables and other liabilities consist of accrued compensation expense, accrued liabilities, lease liabilities, deferred purchase price liabilities, Ginnie Mae reverse mortgage buyout payable, derivative liabilities, deferred tax liability, estimate of claim losses, repurchase reserves, liability for loans eligible for repurchase from Ginnie Mae and warrant liability. The components of payables and other liabilities are detailed in Note 20—Payables and Other Liabilities. Deferred Purchase Price Liabilities As a result of business acquisitions, the Company has recorded contingent liabilities based upon expected future payouts. In accordance with ASC 805, the Company measures any contingent consideration related to business combinations at fair value, and adjusts the reported amount each period with the change in fair value recorded in other, net , IBNR and Estimate of Claim Losses The Company offers medical, dental, and other benefits to its employees. Certain of these medical benefit plans are self-funded by the Company, whereby the Company pays actual claims made by its employees. Any employee-paid portion of these benefits are withheld by the individual operating entities and remitted back to the Company on a monthly basis. In addition, the Company has a stop-loss insurance policy in place which reimburses the Company for extraordinary claims. The Company estimates incurred but not reported obligations, including any existing and future claims (“IBNR”), related to these self-funded benefits on a quarterly basis. The estimated claims are recorded based upon current and future claims expected to be received. In addition, the Company has engaged a third party actuary to validate the reasonableness of the existing estimated claims. The Company is occasionally named as a defendant in claims concerning alleged errors or omissions pertaining to the issuance of title policies or the performance of escrow services. The Company assesses pending and threatened claims to determine whether losses are probable and reasonably estimable in accordance with ASC 450, Contingencies This liability also includes amounts determined on the basis of claim evaluation, estimates for reported losses and estimates for losses incurred but not reported related to the Company’s title and settlement services subsidiary. These estimates are continually reviewed and updated. Any adjustments are reflected currently. Accordingly, loss and loss adjustment expenses are charged to income as incurred. Management believes the liability for loss and loss adjustment expenses is adequate; however, the ultimate liability may be in excess of or less than the amounts provided. Repurchase Reserve The Company has exposure to potential mortgage loan repurchases and indemnifications in its capacity as a seller of mortgage loans. The estimation of the liability for probable loss related to repurchase and indemnification obligations considers: (i) specific, nonperforming loans where the Company has received a repurchase or indemnification request and believes it will be required to repurchase the loan or indemnify the investor for any losses; and (ii) an estimate of probable future repurchase or indemnification obligations for standard representation and warranty provisions, early payment defaults or other recourse obligations. The Company establishes an initial reserve at fair value for expected losses relating to loan sales at the date the loans are derecognized from the Consolidated Statements of Financial Condition, which is recorded as a component of gain on sale and other income from loans held for sale, net, in the Consolidated Statements of Operations. Warrant Liability The Company accounts for warrants for the Company’s Class A Common Stock at fair value within payables and other liabilities on the Consolidated Statements of Financial Condition because the warrants do not meet the criteria for classification within equity. The warrants are subject to remeasurement at each statement of financial condition date and any change in fair value is recognized within other, net in the Consolidated Statements of Operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the warrants. Tax Receivable Agreement Obligation In connection with the Business Combination, concurrently with the Closing, the Company entered into TRAs with certain owners of FoA Equity prior to the Business Combination (the “TRA Parties”). The TRAs generally provide for payment by the Company to the TRA Parties of 85% of the cash tax benefits, if any, that the Company is deemed to realize (calculated using certain simplifying assumptions) as a result of (i) tax basis adjustments as a result of sales and exchanges of units in connection with or following the Business Combination and certain distributions with respect to units, (ii) the Company’s utilization of certain tax attributes attributable to Blackstone Tactical Opportunities Associates—NQ L.L.C., a Delaware limited partnership, shareholders (“Blocker GP”), and (iii) certain other tax benefits related to entering into the TRAs, including tax benefits attributable to making payments under the TRAs. These tax basis adjustments generated over time may increase (for tax purposes) the depreciation and amortization deductions available to the Company and, therefore, may reduce the amount of U.S. federal, state and local tax that the Company would otherwise be required to pay in the future, although the IRS may challenge all or part of the validity of that tax basis, and a court could sustain such challenge. The tax basis adjustments upon sales or exchanges of units for shares of Class A Common Stock and certain distributions with respect to Class A LLC Units may also decrease gains (or increase losses) on future dispositions of certain assets to the extent tax basis is allocated to those assets. Actual tax benefits realized by the Company may differ from tax benefits calculated under the Tax Receivable Agreements as a result of the use of certain assumptions in the TRAs, including the use of an assumed weighted average state and local income tax rate to calculate tax benefits. The payments that FoA may make under the TRAs are expected to be substantial. The payments under the TRAs are not conditioned upon continued ownership of FoA or FoA Equity by the Continuing Unitholders (as defined in Note 4—Acquisitions). The Company accounts for the effects of these increases in tax basis and associated payments under the TRAs arising from exchanges in connection with the Business Combination as follows: • records an increase in deferred tax assets for the estimated income tax effects of the increases in tax basis based on enacted U.S. federal and state tax rates at the date of the exchange; • to the extent we estimate that the Company will not realize the full benefit represented by the deferred tax asset, based on an analysis that will consider, among other things, our expectation of future earnings, the Company reduces the deferred tax asset with a valuation allowance; and • initial measurement of the obligations is at fair value on the date of the Business Combination. Subsequently, the liability will be remeasured at fair value each reporting period, with any changes in fair value recognized in other, net, in the Consolidated Statements of Operations. The Company records obligations under the TRAs resulting from exchanges subsequent to the Business Combination, as they occur, at the gross undiscounted amount of the expected future payments as an increase to the liability along with the deferred tax asset and valuation allowance (if any) with an offset to additional paid-in As of December 31, 2021 (Successor), the Company had a liability of $34.6 million related to its projected obligations under the TRA, which is included in deferred purchase price liabilities within payables and other liabilities on the Consolidated Statements of Financial Condition.
Notes Payable, Net	Notes Payable, Net The Company accounts for outstanding notes payable in accordance with ASC 470— Debt
Reinsurance	Reinsurance The Company assumes and cedes reinsurance with other insurance companies in the normal course of business. Ceded insurance is comprised of excess of loss treaties, which protect against losses over defined amounts. The Company remains liable to the insured for claims under ceded insurance policies in the event the assuming insurance companies are unable to meet their obligations under these contracts. Reinsurance is recorded as a contra revenue within fee income on the Consolidated Statements of Operations.
Comprehensive Income	Comprehensive Income Recognized revenue, expenses, gains and losses are included in operations. Certain changes in assets and liabilities, such as foreign currency translation adjustments, are reported as a separate component in the Consolidated Statements of Equity. Such items, along with net income and losses, are components of comprehensive income (loss). The components of other comprehensive income (loss) are reported in the Consolidated Statements of Comprehensive Income. For the years ended December 31, 2021, 2020, and 2019, the only component of other comprehensive income (loss) was foreign currency translation adjustments, arising from translation of the foreign branch accounts in Manila, Philippines.
Foreign Currency	Foreign Currency The functional currency of the Company’s international branch is the Philippine peso. Foreign currency denominated assets and liabilities are translated into United States dollars using the exchange rates in effect at the dates of the Consolidated Statements of Financial Condition. Results of operations and cash flows are translated using the average exchange rates throughout the period. The resulting exchange rate translation adjustments are included as a component of equity in accumulated other comprehensive income (loss).
Revenue Recognition	Revenue Recognition The Company derives its revenues principally from gains on origination and sale of loans, including revenue fees collected from the borrower at closing, loan servicing fees, fair value gains on originated mortgage loans, net of changes in fair value associated with outstanding HMBS and other nonrecourse obligations, other fee income, and net interest income on loans. Net gains on loans held for sale include realized and unrealized gains and losses on loans held for sale, interest rate lock commitments, related derivatives and retained MSRs. The Company sells mortgage loans into the secondary market, including sales to the GSEs on a servicing-released basis, where the loans are sold to an investor with the associated mortgage servicing rights transferred to the investor or to a separate third party investor. In addition, the Company may opportunistically sell loans on a servicing-retained basis, where the loan is sold and the rights to service that loan are retained. Unrealized gains and losses include fair value gains and losses resulting from changes in fair value in the underlying mortgages, interest rate lock commitments, related derivatives and retained MSRs, from the time of origination to the ultimate sale of the loan or other settlement of those financial instruments. Monthly servicing revenue represents income derived by the Company in relation to the servicing of loans. Interest income reflects interest earned on loans held for sale by the Company prior to sale on the secondary market. The interest income collected on such loans is reported net of the interest expense incurred while the loans are carried on the Company’s warehouse lines. Interest income is recognized using the interest method. Loans are placed on non-accrual non-accrual The majority of revenue generated by the Company in connection with originations and servicing are not within the scope of ASC 606. Based on its evaluation of loan origination fees, the Company has determined that loan origination fees are recorded in fee income in the Consolidated Statements of Operations when a loan is successfully funded, with the related costs recognized in general and administrative expenses when incurred. The primary components of fee income consist of the following: Loan Servicing Fees Loan servicing income represents recurring servicing and other ancillary fees earned for servicing mortgage loans owned by investors. Servicing fees received for servicing mortgage loans owned by investors are based on a stipulated percentage of the outstanding monthly principal balance on such loans, or the difference between the weighted-average yield received on the mortgage loans and the amount paid to the investor, less guaranty fees and interest on curtailments. Loan servicing income is receivable only out of interest collected from mortgagors and is recorded as income when collected. Late charges and other miscellaneous fees collected from mortgagors are also recorded as income when collected, and are included as a component of fee income in the Consolidated Statements of Operations. Loan Origination Fees Loan origination fees are recorded in fee income in the Consolidated Statements of Operations when earned, with the related costs recognized in general and administrative expenses when incurred at the date of origination. The Company collects from the borrower certain amounts, including underwriting fees, credit reporting fees, loan administration and appraisal fees. The Company has determined that it is primarily responsible for fulfillment and acceptability for these services, and has discretion in setting the price to the borrower, and therefore these fees should be recognized gross as the Company is the principal for the specified goods and services performed. In addition to the fees above, the Company also acts as agent for certain services for its customers. These services include obtaining flood certification, credit reporting, and inspection fees. In these transactions, the Company will facilitate the providing of the goods or services to prospective borrowers, and collects these amounts from the borrower prior to the services being provided. These amounts are included as a component of fee income in the Consolidated Statements of Operations. Agents National Title Insurance Company (“ANTIC”), a subsidiary of the Company, issues title insurance products through a network of title insurance agents throughout the country. Title insurance is a product providing coverage to parties within a real estate transaction according to the respective state regulatory bodies in the United States of America. Insurance premium revenue is recognized from title insurance contracts when the title agents report the issuance of a title insurance policy. The revenue stream falls under ASU 2016-20, Revenue from Contracts with Customers Financial Services-Insurance 944-605 The Company recognizes revenues from services provided in accordance with the five-step process outlined in ASC 606. Revenue is recognized when the performance obligations have been satisfied by transferring control of a product or service to a customer in an amount that reflects the consideration that the Company expects to receive. This revenue can be recognized at a point in time or over time. Other Fee Income Title and Closing Services : The Company generates revenue by providing title agent and closing services for lenders in connection with loan closings. Specific fees are specified within each lenders/financial institutions’ agreements. While the services are generally performed over a 90 -day time frame leading up to and finalized before the date of loan closing, no fees are earned and recorded unless the loan closing occurs. Net fees are issued to the Company at the time of the respective loan closing. The specific good and/or service provided to the customer is the issuance of title insurance policy. The risk in the title issuance lies mostly with the title underwriter of the insurance policy and less on the Company, as the agent, thus the Company determined within step 5 of ASC 606 that the Company does not control the goods or service before it is transferred to the customer. The Company recognizes net revenue at a point in time using the output method, specifically as services are completed in connection with the performance of said obligations. There are two performance obligations, the first is the search and examination of the title of a property, which is performed by the Company on behalf of the underwriter. The second is the issuance of a title insurance policy, which is performed by an independent underwriter. The transaction price is allocated between the performance obligations based on the terms of the transaction agreement. These amounts are included as a component of fee income in the Consolidated Statements of Operations. Settlement, Appraisal and Other Services : Settlement, appraisal and other services include specific real estate transaction services provided to customers to facilitate the origination of mortgage loans. Revenue is recognized when the performance obligations have been satisfied by transferring control of a product or service to a customer in an amount that reflects the consideration that the Company expects to receive. The Company recognizes gross revenue at a point in time using the output method, specifically as services are completed in connection with the performance of said obligations. The Company earns appraisal revenue through the one performance obligation of managing the appraisal process for a consumer to obtain an independent valuation of a property to be mortgaged. The appraisal management company maintains a pool of qualified appraisers, who on behalf of the lender provide an appraisal report for a property. Gross revenue is earned and recognized at a point in time using the output method when each appraisal is performed and completed. These amounts are included as a component of fee income in the Consolidated Statements of Operations. There are no variable consideration or significant judgments or estimates when revenue is recognized for this stream in accordance with ASC 606. Transactional Revenue in-school Hedge Advisory Services: Company may also be entitled to receive incentive compensation (the “at-risk fee”) tied to the performance of the MSR portfolio, which will generally vary between 5% and 15% of net gains. The at-risk fee is typically calculated and paid monthly. The Company recognizes gross revenues over time utilizing the output method. These amounts are included as a component of fee income in the Consolidated Statements of Operations. Other advisory fees: In addition to the management fee and incentive fee, the Company may also receive expense reimbursements from its clients in accordance with applicable advisory or sub-advisory agreements and other governing documents. These may include but are not limited to, reimbursement for expenses associated with legal entity formation and capital raising activities, initial public offering costs and expenses, fund administration costs, professional fees, securitization costs, custodian and transfer agent costs and certain other out-of-pocket expenses. To the extent such reimbursements are provided, the Company recognizes these amounts as a component of fee income in the Consolidated Statements of Operations. The Company recognizes gross revenues over time utilizing the output method. MSR Trade Broker: The Company’s one performance obligation for these services is providing brokerage services to its clients. Services include analysis, structuring, marketing and negotiation of transactions for servicing portfolios in the secondary market. The Company earns revenue based on fees resulting from the trade of MSR assets. Trading of MSR assets is done in two ways: 1) co-issue, flow arrangement for the exit of a pipeline on a per loan basis, and 2) bulk, sale of an entire MSR portfolio. Fees on these brokered trades are based upon a dollar per loan or basis points on UPB of underlying loans. Fees are defined in agreements with clients. Service is completed at the settlement date. The Company recognizes gross revenue at a point in time when the services are performed utilizing the output method. These amounts are included as a component of fee income in the Consolidated Statements of Operations. OAS & MSR Valuation Services: The Company has performance obligation for these services which is providing the analytic valuation services specified in the client-specific statement of work. Services are rendered when valuation results are complete and delivered to the client. The Company recognizes gross revenue at a point in time in which the services are performed using the output method. These amounts are included as a component of fee income in the Consolidated Statements of Operations. Contract Balances A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity’s obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. The Company’s non-interest month-end The Company has other revenue streams that are considered insignificant to the overall business. These services are negotiated with customers based on separate contracts for each of the respective services. These revenue streams are also recognized over time using the output method and contain only one performance obligation. There is no significant variable consideration or significant judgments or estimates when revenue is recognized for the Company’s revenue streams in accordance with ASC 606.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (i) the assets have been isolated from the Company, put presumptively beyond the reach of the entity, even in bankruptcy, (ii) the transferee (or if the transferee is an entity whose sole purpose is to engage in securitization and that entity is constrained from pledging or exchanging the assets it receives, each third party holder of its beneficial interests) has the right to pledge or exchange the transferred financial assets, and (iii) the Company or its agents does not maintain effective control over the transferred financial assets or third party beneficial interest related to those transferred assets through an agreement to repurchase them before their maturity. When the Company determines that control over the transfer of financial assets has been surrendered, the transaction will be accounted for as a sale in which the underlying mortgage loans are derecognized, and a corresponding gain recorded equal to the proceeds of the cash and any other beneficial interest retained by the Company, less the carrying balance of the transferred mortgage loans. Upon completion of the sale, the recorded gains and losses are reflected in gain on sale and other income from loans held for sale, net in the Consolidated Statements of Operations. Whenever the requirements for sale treatment have not been met due to control over the transferred financial assets not being surrendered, the transferred loans will continue to be held as mortgage loans held for investment, subject to nonrecourse debt, at fair value, and an associated liability is recorded in nonrecourse debt, at fair value on the Consolidated Statements of Financial Condition.
Equity-Based Compensation	Equity Based Compensation Equity based compensation with service conditions made to employees is measured based on the grant date fair value of the awards and recognized as compensation expense over the period during which the recipient is required to perform services in exchange for the award (the requisite service period). The Company has elected to use a straight-line attribution method for recognizing compensation costs relating to awards that have service conditions only. Forfeitures are recorded as they occur. For equity based compensation where there are market conditions as well as service conditions to vesting, the grant date fair value of the awards is recognized as compensation expense using the graded-vesting method over the requisite service period for each separately vesting tranche of the award as if they were multiple awards.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred. For the Successor period April 1, 2021 to December 31, 2021 and Predecessor period January 1, 2021 to March 31, 2021 the Company recorded $30.8 million and $10.6 million in advertising expense, respectively. For the years ended December 31, 2020, and 2019 (Predecessor), the Company recorded $37.5 million and $27.2 million, respectively, in advertising and related expenses which are included in general and administrative expenses in the Consolidated Statements of Operations for all periods.
Income Taxes	Income Taxes Prior to the Business Combination, a portion of FoA Equity’s earnings were subject to certain U.S. federal and foreign taxes. Subsequent to the Business Combination, the portion of earnings allocable to FoA is subject to corporate level tax rates at the federal, state and local levels. Therefore, the amount of income taxes recorded prior to the Business Combination are not representative of the expenses expected subsequent to the Business Combination. The computation of the effective tax rate and provision (benefit) at each period requires the use of certain estimates and significant judgments including, but not limited to, the expected operating income for the year, projections of the proportion of income that is subject to tax, permanent differences between the Company’s GAAP earnings and taxable income, and the likelihood of recovering deferred tax assets existing as of the statement of financial condition date. The estimates used to compute the provision (benefit) for income taxes may change throughout the year as new events occur, additional information is obtained or as tax laws and regulations change. Accordingly, the effective tax rate for future periods may vary materially. The Company accounts for income taxes pursuant to the asset and liability method, which requires it to recognize current tax liabilities or receivables for the amount of taxes it estimates are payable or refundable for the current year, deferred tax assets and liabilities for the expected future tax consequences attributable to temporary differences between the financial statement carrying amounts and their respective tax bases of assets and liabilities and the expected benefits of net operating loss and credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period enacted. A valuation allowance is provided when it is more likely than not that a portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income and the reversal of deferred tax liabilities during the period in which related temporary differences become deductible. The benefit of tax positions taken or expected to be taken in the Company’s income tax returns is recognized in the financial statements if such positions are more likely than not of being sustained upon examination by taxing auth
Contingencies	Contingencies The Company evaluates contingencies based on information currently available and will establish accruals for those matters when a loss contingency is considered probable and the related amount is reasonably estimable. For matters where a loss is believed to be reasonably possible but not probable, no accrual is established, but the nature of the loss contingency and an estimate of the reasonably possible range of loss in excess of amounts accrued, when such estimate can be made, is disclosed. In deriving an estimate, the Company is required to make assumptions about matters that are, by their nature, highly uncertain. The assessment of loss contingencies, including legal contingencies, involves the use of critical estimates, assumptions and judgments. Whenever practicable, the Company consults with outside experts, including legal counsel and consultants, to assist with the gathering and evaluation of information related to contingent liabilities. It is not possible to predict or determine the outcome of all loss contingencies. Accruals are periodically reviewed and may be adjusted as circumstances change. See Note 26—Commitments and Contingencies for further discussion.
Seller Earnout	Seller Earnout The equity owners of FoA Equity prior to the Closing are entitled to receive an earnout exchangeable for Class A Common Stock if, at any time during the six years following Closing, the volume weighted average price (the “VWAP”) of Class A Common Stock with respect to a trading day is greater than or equal to $12.50 for any 20 trading days within a consecutive 30 -trading-day period (“First Earnout Achievement Date”), 50 % of the earnout units issued to sellers (in conjunction with the Sponsor shares defined below, the “Earnout Securities”) will be issued; and if, at any time during the six years following Closing, the VWAP is greater than or equal to $15.00 for any 20 trading days within a consecutive 30 -trading-day period, the remaining 50% of the Earnout Securities will be issued (“Second Earnout Achievement Date”). The seller earnout is accounted for as contingent consideration and classified as equity. The seller earnout was measured at fair value upon the consummation of the Business Combination, the date of issuance, and will not be subsequently remeasured. The settlement of the seller earnout will be accounted for within equity, if and when, the First or Second Earnout Achievement Date occurs.
Sponsor Earnout	Sponsor Earnout The Company classified the Sponsor Earnout Agreement as an equity transaction measured at fair value upon the consummation of the Business Combination, the date of issuance, and will not be subsequently remeasured. Additionally, the settlement of the Sponsor Earnout Agreement will be accounted for within equity, if and when the First or Second Sponsor Earnout Achievement Date occurs. See Note 40—Equity for additional information.
Noncontrolling Interest	Noncontrolling Interest Noncontrolling interest represents the Company’s noncontrolling interest in consolidated subsidiaries which are not attributable, directly or indirectly, to the controlling Class A Common Stock ownership of the Company. Net income (loss) is reduced by the portion of net income (loss) that is attributable to noncontrolling interests as well as special allocations related to the Amended and Restated Long-Term Incentive Plan (“A&R MLTIP”) as defined in the FoA Equity LLC Agreement.
Earnings Per Share	Earnings Per Share Basic net income (loss) per share is based on the weighted average number of shares of Class A Common Stock issued and outstanding during the Successor periods. Diluted net income (loss) per share is based on the weighted average number of shares of Class A Common Stock issued and outstanding and the effect of all dilutive common stock equivalents and potentially dilutive equity based compensation awards outstanding during the Successor periods. For the Predecessor periods, FoA Equity’s capital structure consisted of a single class of outstanding membership units which were held by one member, UFG. Therefore, the Company omitted earnings per unit for the Predecessor periods presented due to the limited number of LLC unit holders.
Reclassifications	Reclassifications Certain amounts from the prior year consolidated financial statements have been reclassified to conform to the current year financial presentation.

Debt Instrument, Covenant Description	The Company’s borrowing arrangements and credit facilities contain various financial covenants which primarily relate to required tangible net worth amounts, liquidity reserves, leverage requirements, and profitability requirements.
Debt Instrument, Covenant Compliance	The terms of the Company’s financing arrangements and credit facilities contain covenants, and the terms of the Company’s GSE/seller servicer contracts contain requirements that may restrict the Company and its subsidiaries from paying distributions to its members. These restrictions include restrictions on paying distributions whenever the payment of such distributions would cause FoA to no longer be in compliance with any of its financial covenants or GSE requirements. Further, the Company is generally prohibited under Delaware law from making a distribution to a member to the extent that, at the time of the distribution, after giving effect to the distribution, liabilities of the Company (with certain exceptions) exceed the fair value of its assets. Subsidiaries of the Company are generally subject to similar legal limitations on their ability to make distributions to FoA.
