Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies	Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies Description of Business Flagstar Bancorp, Inc., is a savings and loan holding company founded in 1993. The Company's business is primarily conducted through its principal subsidiary, Flagstar Bank, FSB (the "Bank"), a federally chartered stock savings bank founded in 1987. We are one of the largest banks headquartered in Michigan. When we refer to "Flagstar", "the Company", "we", "our", or "us," we mean Flagstar Bancorp, Inc. and our consolidated subsidiaries. The Company is subject to regulation, examination and supervision by the Federal Reserve. The Bank is subject to regulation, examination and supervision by the OCC of the U.S. Department of the Treasury, the CFPB and the FDIC. The Bank is a member of the FHLB of Indianapolis and its deposits are insured by the FDIC through the Deposit Insurance Fund. Consolidation and Basis of Presentation Our accounting and financial reporting policies conform to accounting principles generally accepted in the United States. Additionally, where applicable the policies conform to the accounting and reporting guidelines prescribed by regulatory authorities. Certain prior period amounts have been reclassified to conform to the current period presentation. The preparation of the Consolidated Financial Statements, requires Management to make estimates and assumptions that affect reported amounts of assets and liabilities, revenues and expenses and disclosures of contingent assets and liabilities. Actual results could be materially different from these estimates. On April 26, 2021, it was announced that New York Community Bancorp, Inc. ("NYCB") and Flagstar had entered into a definitive merger agreement (the "Merger Agreement") under which the two companies will combine in an all stock merger. Under the terms of the Merger Agreement, Flagstar shareholders will receive 4.0151 shares of NYCB common stock for each Flagstar share they own. The combined company expects to have over $85 billion in assets and operate nearly 400 traditional branches in nine states and over 80 loan production offices across a 28 state footprint. On August 4, 2021, Flagstar's and NYCB's shareholders each voted in their respective special meetings of shareholders to approve the proposed business combination. The transaction is subject to customary closing conditions, including regulatory approvals. Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents include cash on hand, amounts due from correspondent banks and the FRB, and short-term investments that have a maturity at the date of acquisition of three months or less and are readily convertible to cash. Restricted cash includes cash that the Bank pledges as maintenance margin on centrally cleared derivatives and is included in other assets on the Consolidated Statements of Financial Condition. Investment Securities We measure securities classified as AFS at fair value, with unrealized gains and losses, net of tax, included in other comprehensive income (loss) in stockholders’ equity. We recognize realized gains and losses on AFS securities when securities are sold. The cost of securities sold is based on the specific identification method. Any gains or losses realized upon the sale of a security are reported in other noninterest income in the Consolidated Statements of Operations. The fair value of investment securities is based on observable market prices, when available. If observable market prices are not available, our valuations are based on alternative methods, including: quotes for similar fixed-income securities, matrix pricing, or discounted cash flow methods. Fair values are obtained through an independent third party utilizing a pricing service and are compared to independent pricing sources on a quarterly basis. For further information, see Note 2 - Investment Securities and Note 20 - Fair Value Measurements. Investment securities HTM are carried at amortized cost and are adjusted for the amortization of premiums and accretion of discounts using the interest method. Transfers of investment securities into the HTM category from the AFS category are accounted for at fair value at the date of transfer. Any related unrealized holding gain (loss), net of tax, that was included in the transfer is retained in other comprehensive income (loss) and is amortized as an adjustment to interest income over the remaining life of the securities. We separately evaluate our HTM debt securities for any credit losses. For each of the years in the three-year period ended December 31, 2021, all of our investment securities HTM were issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses; therefore, we apply a zero credit loss assumption to this portfolio and did not record any credit allowance for each of the three years ended December 31, 2021. We evaluate AFS debt securities where the value has declined below amortized cost for impairment. If we intend to sell or believe it is more likely than not that we will be required to sell the debt security, it is written down to fair value through earnings. For AFS debt securities we intend to hold, we evaluate the debt securities for expected credit losses, except for debt securities that are guaranteed by the U.S. Treasury, U.S. government agencies or sovereign entities of high credit quality for which we apply a zero loss assumption and comprised 82 percent of our AFS portfolio at December 31, 2021. For the remaining AFS securities, any decline in fair value that is related to market factors is recognized in OCI and credit losses are recognized as an increase to the ACL through the credit loss provision. For each of the years in the three-year period ended December 31, 2021, we had no unrealized credit losses. Investment securities transactions are recorded on the trade date for purchases and sales. Interest earned on investment securities, including the amortization of premiums and the accretion of discounts, are determined using the effective interest method over the period of maturity and recorded in interest income in the Consolidated Statements of Operations. Accrued interest receivable on investment securities totaled $4 million at December 31, 2021 and was reported in Other assets on the Consolidated Statements of Financial Condition. Loans Held-for-Sale We classify loans as LHFS when we originate or purchase loans that we intend to sell. We have elected the fair value option for the majority of our LHFS. We estimate the fair value of mortgage loans based on quoted market prices for securities backed by similar types of loans, where available, or by discounting estimated cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. Changes in fair value are recorded to other noninterest income on the Consolidated Statements of Operations. LHFS that are recorded at lower of cost or fair value may be carried at fair value on a nonrecurring basis when the fair value is less than cost. For further information, see Note 20 - Fair Value Measurements. Loans that are transferred into the LHFS portfolio from the LHFI portfolio, due to a change in intent, are recorded at the lower of cost or fair value. Gains or losses recognized upon the sale of loans are determined using the specific identification method. Loans Held-for-Investment We classify loans that we have the intent and ability to hold for the foreseeable future or until maturity as LHFI. Loans held-for-investment are reported at their amortized cost, which includes the outstanding principal balance adjusted for any unamortized premiums, discounts, deferred fees and costs. Accrued interest receivable on loans held-for-for investment totaled $35 million at December 31, 2021 and was reported in Other assets on the Consolidated Statements of Financial Condition. Premiums and discounts on purchased loans and non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, are deferred and recognized over the life of the related loans as an adjustment to the loans’ effective yield, which is included in interest income on loans in the Consolidated Statements of Operations. Loans originally classified as LHFS, for which we have elected the fair value option, and subsequently transferred to LHFI continue to be measured and reported at fair value on a recurring basis. Changes in fair value are recorded to other noninterest income on the Consolidated Statements of Operations. The fair value of these loans is determined using the same methods described above for LHFS. For further information, see Note 20 - Fair Value Measurements. When loans originally classified as LHFS or as LHFI are reclassified due to a change in intent or ability to hold, cash flows associated with the loans are classified in the Consolidated Statements of Cash Flows as operating or investing, in accordance with the initial classification of the loans. Past Due, Impaired and Modified (Troubled Debt Restructuring) Loans Loans are considered to be past due when any payment of principal or interest is 30 days past the scheduled payment date. While it is the goal of Management to collect on loans, we attempt to work out a satisfactory repayment schedule or modification with past due borrowers and will undertake foreclosure proceedings if the delinquency is not satisfactorily resolved. Our practices regarding past due loans are designed to both assist borrowers in meeting their contractual obligations and minimize losses incurred by the bank. We cease the accrual of interest on all classes of consumer and commercial loans upon the earlier of, becoming 90 days past due, or when doubt exists as to the ultimate collection of principal or interest (classified as nonaccrual or NPLs). When a loan is placed on nonaccrual status, the accrued interest income is reversed against interest income and the loan may only return to accrual status when principal and interest become current and are anticipated to be fully collectible. We do not measure an ACL for accrued interest receivables as accrued interest is written off in a timely manner. Loans are considered impaired if it is probable that payment of all interest and principal will not be made in accordance with the original contractual terms of the loan agreement or when any portion of principal or interest is 90 days past due. This classification includes both performing and nonperforming modified loans. For further information, see Note 4 - Loans Held-for-Investment. When a loan is considered impaired, the accrual of interest income is discontinued until the receipt of principal and interest is no longer in doubt. Interest income is recognized on impaired loans using a cost recovery method unless amounts contractually due are not in doubt. Cash received on nonperforming impaired loans is applied entirely against principal until the loan has been collected in full, after which time any additional cash receipts are recognized as interest income. Loan Modifications (Troubled Debt Restructurings) We may modify certain loans in both our consumer and commercial loan portfolios to retain customers or to maximize collection of the outstanding loan balance. We have programs designed to assist borrowers by extending payment dates or reducing the borrower's contractual payments. All loan modifications are made on a case-by-case basis. Our standards relating to loan modifications consider, among other factors, minimum verified income requirements, cash flow analysis and collateral valuations. TDRs result in those instances in which a borrower demonstrates financial difficulty and for which a concession has been granted, including reductions of interest rates, extensions of amortization periods, principal and/or interest forgiveness and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral. These loans are classified as nonperforming TDRs if the loan was nonperforming prior to the restructuring, or based upon the results of a contemporaneous credit evaluation. Such loans will continue on nonaccrual status until the borrower has established a willingness and ability to make the restructured payments for at least six months, after which they will be classified as performing TDRs and will begin to accrue interest. Performing and nonperforming TDRs remain impaired as interest and principal will not be received in accordance with the original contractual terms of the loan agreement. Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, but may give rise to potential incremental losses. We measure impairments using a discounted cash flow method for performing TDRs and measure impairment based on collateral values for collateral-dependent nonperforming TDRs. Beginning in March 2020, as a response to COVID-19, we offered our consumer borrowers principal and interest payment deferrals, forbearance and/or extensions up to a maximum period of 18 months. We considered these programs in the context of whether or not the short-term modifications of these loans would constitute a TDR. We considered the CARES Act, interagency guidance and related guidance from the FASB, which provided that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not required to be accounted for as TDRs. As a result, we have determined that loan forbearance, modifications, deferrals and extensions made under these COVID-19 programs are not TDRs. Allowance for Credit Losses on Loans We determine the estimate of the ACL on at least a quarterly basis. The ACL represents Management's estimate of expected lifetime losses in our LHFI portfolio, excluding loans carried under the fair value option. In addition, we record a reserve for expected lifetime losses on our unfunded commitments - see Reserve for Unfunded Commitments section below. Therefore, we record ALLL on relevant financial assets and a reserve for unfunded commitments on our Consolidated Statements of Financial Condition, collectively referred to as the ACL. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual terms exclude expected extensions, renewals, and modifications unless the following applies: Management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by us. The ACL is impacted by changes in asset quality of the portfolio, including but not limited to increases in risk rating changes in our commercial portfolio, borrower delinquencies, changes in FICO scores or changes in LTVs in our consumer portfolio. In addition, while we have incorporated our forecasted impact of COVID-19 into our ACL, the ultimate impact of COVID-19 is still uncertain, including how long economic activity will be impacted by the pandemic and what effect the unprecedented levels of government fiscal and monetary actions will have on the economy and our credit losses. Specifically identified component. The specifically identified component of ACL related to performing TDR loans is generally measured as the difference between the recorded investment in the specific loan and the present value of the cash flows expected to be collected, discounted at the loan's original effective interest rate. Estimating the timing and amounts of future cash flow projections is highly judgmental and based upon assumptions including default rates, prepayment probability and loss severities. All of these estimates and assumptions require significant management judgment and certain assumptions are highly subjective. Specifically identified collateral dependent NPL loans are generally measured as the difference between the recorded investment in the impaired loan and the underlying collateral value less estimated costs to sell. These estimates are dependent on third-party property valuations which may be influenced by factors such as the current and future level of home prices, the duration of current overall economic conditions, and other macroeconomic and portfolio-specific factors. Model-based component . A general allowance is established for lifetime losses inherent on non-impaired loans by segmenting the portfolio based upon common risk characteristics. Our consumer loan portfolio is segmented into Residential First Mortgage, Home Equity and Other Consumer. Loan characteristics impacting these segments include lien position, credit quality, and loan structure. At a high-level, our commercial loans are segmented into Commercial Real Estate, Commercial and Industrial, and Warehouse Lending. Loan characteristics impacting these segments include credit quality and loan structure. We measure the allowance using the applicable dual risk rating model which measures probability of default, loss given default and exposure at default. As of December 31, 2021, we utilized the Moody’s November 2021 economic scenarios in our forecast, which were materially consistent with the December scenarios: a growth forecast, weighted at 30 percent; a baseline forecast, weighted at 40 percent; and an adverse forecast, weighted at 30 percent. Within our composite forecast, unemployment ends 2021 at 5 percent and will recover slightly in 2022, ending the year just under 5 percent. GDP continues to recover throughout 2022 and returns to pre-COVID levels in 2023. HPI decreases by just over 1 percent compared to 2021 year-end levels through the second quarter of 2022 before returning to 2021 year-end levels by the third quarter of 2022. In 2021, we judgmentally decreased our qualitative reserves by $65 million which primarily reflected our best estimates of COVID-19’s impact on our portfolios (including the estimated impact of government stimulus, forbearance/payment holidays, and Fed programs. This decline was primarily driven by a decrease in the model output from Moody’s adverse scenario, improvement in credit performance of previously identified industries and borrowers we believed could be more exposed to the stressful conditions in our forecast and decreased loans in forbearance. Qualitative adjustments . The specifically identified component analysis and the output of the model provide a reasonable starting point for our analysis, but do not, by themselves, form a sufficient basis to determine the appropriate level for the ACL. We therefore consider the qualitative factors that are likely to cause the ACL associated with our existing portfolio to differ from the output of the model. The most significant qualitative factors considered include changes in economic and business conditions, changes in nature and volume of portfolio and changes in the volume and severity of past due loans. The application of different inputs into the model calculation and the assumptions used by Management to adjust the model calculation are subject to significant management judgment and may result in actual credit losses that differ from the originally estimated amounts. Reserve for Unfunded Commitments We estimate expected credit losses over the contractual period in which we are exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by us. The ACL on unfunded commitments is adjusted as a provision for credit loss expense within the provision (benefit) for credit losses on the Consolidated Statements of Operations and is recorded in other liabilities on the Consolidated Statements of Financial Condition. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. The reserve for unfunded commitments is included in other liabilities on the Consolidated Statements of Financial Condition. These credit exposures include unfunded loans with available balances, new commitments to lend that are not yet funded, and standby and commercial letters of credit. For further information, see Note 19 – Legal Proceedings, Contingencies and Commitments. Transfers of Financial Assets Our recognition of gain or loss on the sale of loans for which we surrender control is accounted for as a sale to the extent that 1) the transferred assets are legally isolated from us or our consolidated affiliates, even in bankruptcy or other receivership, 2) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company and 3) we do not maintain the obligation or unilateral ability to reclaim or repurchase the assets. If the sale criteria are met, the transferred financial assets are removed from the Consolidated Statements of Financial Condition and a gain or loss on sale is recognized. Variable Interest Entities An entity that has a controlling financial interest in a VIE is referred to as the primary beneficiary and consolidates the VIE. An entity is deemed to have a controlling financial interest and is the primary beneficiary of a VIE if it has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. For further information, see Note 7 - Variable Interest Entities. Repossessed Assets Repossessed assets include one-to-four family residential property, commercial property and one-to-four family homes under construction that were acquired through foreclosure or acceptance of a deed-in-lieu of foreclosure. Repossessed assets are initially recorded in other assets at the estimated fair value of the collateral less estimated costs to sell. Losses arising from the initial acquisition of such properties are charged against the allowance for loan losses at the time of transfer. Subsequent valuation adjustments to reflect fair value, as well as gains and losses on disposal of these properties, are charged to general, administrative and other within noninterest expense in the Consolidated Statements of Operations as incurred. For further information, see Note 6 - Repossessed Assets and Note 20 - Fair Value Measurements. Loans with Government Guarantees We originate government guaranteed loans which are pooled and sold as Ginnie Mae MBS. Pursuant to Ginnie Mae servicing guidelines, we have the unilateral right to repurchase loans securitized in Ginnie Mae pools that are due, but unpaid, for three consecutive months. As a result, once the delinquency criteria have been met, and regardless of whether the repurchase option has been exercised, we account for the loans as if they had been repurchased. We recognize the loans and corresponding liability as loans with government guarantees and loans with government guarantees repurchase options, respectively, in the Consolidated Statements of Financial Condition. If the loan is repurchased, the liability is cash settled and the loan with government guarantee remains. Once repurchased, we work to cure the outstanding loans such that they are re-eligible for sale or may begin foreclosure and recover losses through a claims process with the government agency, as an approved lender. Federal Home Loan Bank Stock We own stock in the FHLB of Indianapolis, as required to permit us to obtain membership in and to borrow from the FHLB. The stock is redeemable at par and is carried at cost as no market quotes exist for the stock. Premises and Equipment Premises and equipment are carried at cost less accumulated depreciation. Land is carried at cost. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, which generally ranges from three Goodwill and Intangible Assets The excess of the cost of an acquisition over the fair value of the net assets acquired consists primarily of goodwill, core deposit intangibles and other identifiable intangible assets. Goodwill is not amortized, but rather tested annually for impairment, or more frequently as events occur or circumstances change that would indicate the fair value is below the carrying amount. The Company may assess qualitative factors to determine whether it is more-likely-than-not the fair value is less than its carrying amount. If the Company concludes based on the qualitative assessment that goodwill may be impaired, a quantitative one-step impairment test would then be applied. An impairment loss would be recognized for any excess of carrying value over the fair value of the goodwill. Intangible assets subject to amortization are amortized over the estimated life, using a method that approximates the time the economic benefits are realized by the Company. Intangible assets are reviewed for impairment only when there is a trigger event or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Amortization expense on intangible assets was $11 million and $13 million for the years ended December 31, 2021 and December 31, 2020, respectively. The estimated future aggregate amortization expense on intangible assets for the years ended 2022, 2023, and 2024 is $9 million, $7 million, and $6 million respectively. Mortgage Servicing R ights We purchase and originate mortgage loans for sale to the secondary market and sell the loans on either a servicing-retained or servicing-released basis. If we retain the right to service the loan, an MSR is created at the time of sale which is recorded at fair value. We use an internal valuation model that utilizes an option-adjusted spread, constant prepayment speeds, costs to service and other assumptions to determine the fair value of MSRs. Management obtains third-party valuations of the MSR portfolio on a quarterly basis from independent valuation services to assess the reasonableness of the fair value calculated by our internal valuation model. Changes in the fair value of our MSRs are reported on the Consolidated Statements of Operations in net return on mortgage servicing. For further information, see Note 10 - Mortgage Servicing Rights and Note 20 - Fair Value Measurements. We periodically enter into agreements to sell certain of our MSRs, which qualify as sales transactions. A transfer of servicing rights related to loans previously sold qualifies as a sale at the date on which title passes if substantially all risks and rewards of ownership have irrevocably passed to the transferee and any protection provisions retained by the transferor are minor and can be reasonably estimated. In addition, if a sale is recognized and only minor protection provisions exist, a liability is accrued for the estimated obligation associated with those provisions. Leases Effective January 1, 2019, we adopted the requirements of ASU 2016-02, Leases (Topic 842) and all related amendments. The Company elected to apply the practical expedient of forgoing the restatement of comparative periods. In addition, we elected the practical expedients permitted under transition guidance to not reassess leases entered into prior to adoption. As permitted under ASC 842, the Company made an accounting policy election to exempt leases with an initial term of twelve months or less from balance sheet recognition. Instead, short-term leases are expensed over the lease term with no impact to the balance sheet. At December 31, 2019, our inventory of leases included various bank branches, ATM locations and retail home lending offices. Many of our leases contain options to extend or terminate early and we consider these options when evaluating the lease term to determine if they are reasonably certain to be exercised based on all relevant economic and financial factors. Lease rental expense totaled approximately $15 million, $13 million, and $12 million for the years ended December 31, 2021, 2020 and 2019, respectively. All leases are classified as operating leases based on their terms. The following table reflects information relating to our operating leases: December 31, 2021 (Dollars in millions) Operating Leases (1) Weighted-average remaining lease term (years) 3.66 Weighted-average discount rate 1.3 % Right-of-use asset (2) $ 18 Lease liability (3) $ 21 (1) Lease expense on operating leases includes a de-minimis amount of short-term lease expense and variable lease expense. (2) Recorded in premises and equipment (3) Recorded in other liabilities The following table presents our undiscounted cash flows on our operating lease liabilities as of December 31, 2021 and our minimum contractual obligations on our operating leases as of December 31, 2020: December 31, 2021 December 31, 2020 (Dollars in millions) Within one year $ 9 $ 9 After one year and within two years 8 8 After two years and within three years 5 5 After three years and within four years 4 3 After four years and within five years 2 2 After five years 1 1 Total (1) $ 29 $ 28 (1) The difference between the total undiscounted cash payments on operating leases and the lease liability is solely the effect of discounting. Servicing Fee Income Servicing fee income, late fees and ancillary fees received on loans for which we own the MSR are included in net return on mortgage servicing rights on the Consolidated Statements of Operations. The fees are based on the outstanding principal and are recorded as income when earned. Subservicing fees, which are included in loan administration income on the Consolidated Statements of Operations, are based on a contractual monthly amount per loan including late fees and other ancillary income. Revenue from Contracts with Customers Under the guidance of the Revenue from Contracts with Customers (Topic 606), an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration received in exchange for those goods or services. Revenue is recognized when obligations, under the terms of a contract with our customer, are satisfied, which generally occurs when services are performed. Revenue is measured as the amount of consideration we expect to receive in exchange for providing services. The disaggregation of our revenue from contracts with customers is provided below: For the Years Ended December 31, Location of Revenue (1) 2021 2020 (Dollars in millions) Deposit account and other banking income Deposit fees and charges $ 22 $ 21 Debit card interchange fees Deposit fees and charges 12 11 Credit card interchange fees Other noninterest income 1 1 Wealth management Other noninterest income 8 8 Total $ 43 $ 41 (1) Recognized within the Community Banking segment. Deposit account and other banking income - We charge depositors various deposit account service fees including those for outgoing wires, overdrafts, stop payments, and ATM fees. These fees are generated from a depositor’s option to purchase services offered under the contract and are only considered a contract when the depositor exercises their option to purchase these account services. Therefore, we deem the term of our contracts with depositors to be day-to-day and do not extend beyond the services already provided. Deposit account and other banking fees are recorded at the point in time we perform the requested service. Interchange income - We collect interchange fee income when debit cards that we have issued to our customers, are used in merchant transactions. Our performance obligation is satisfied and revenue is recognized at the point we initiate the payment of funds from a customer’s account to a merchant account. Merchant fee income - We receive a percentage of merchant fees based upon card transactions processed through point-of-sale terminals at referred merchant locations. Our performance obligation is satisfied when our referral of a merchant to a payment processing vendor results in an executed agreement between the merchant and the vendor. Merchant fee revenue is recognized as received. Wealth management revenue - We earn commission income through a revenue share program based on a tiered percentage of total gross commissions generated from the sales of investment and in

We evaluate AFS debt securities where the value has declined below amortized cost for impairment. If we intend to sell or believe it is more likely than not that we will be required to sell the debt security, it is written down to fair value through earnings. For AFS debt securities that we intend to hold, we evaluate the debt securities for expected credit losses, except for debt securities that are guaranteed by the U.S. Treasury, U.S. government agencies or sovereign entities of high credit quality for which we apply a zero loss assumption, and which comprised 82% of our AFS portfolio as of December 31, 2021. For the remaining AFS securities, credit losses are recognized as an increase to the ACL through the credit loss provision. If any of the decline in fair value is related to market factors, that amount is recognized in OCI. We had no unrealized credit losses during the years ended December 31, 2021, 2020 and 2019. We separately evaluate our HTM debt securities for any credit losses. As of December 31, 2021 and December 31, 2020, our entire HTM portfolio qualified for the zero loss assumption as all securities are guaranteed by the U.S. Treasury or U.S. government agencies. Investment securities transactions are recorded on the trade date for purchases and sales. Interest earned on investment securities, including the amortization of premiums and the accretion of discounts, is determined using the effective interest method over the period of maturity and recorded in interest income in the Consolidated Statements of Operations. Accrued interest receivable on investment securities totaled $4 million at December 31, 2021 and $5 million at December 31, 2020, and was reported in other assets on the Consolidated Statements of Financial Condition. Available-for-sale securities Securities AFS are carried at fair value. Unrealized gains and losses on AFS securities are reported as a component of other comprehensive income. We purchased $408 million of AFS securities, which were comprised of U.S. government sponsored agency MBS, certificates of deposit, and corporate debt obligations during the year-ended December 31, 2021. In addition, we retained $254 million in our own private MBS during the twelve months ended December 31, 2021. We retained $18 million of passive interest in our own private MBS during the twelve months ended December 31, 2020. There were no sales of AFS securities during the twelve months ended December 31, 2021 and 2020, other than those related to mortgage loans that had been securitized for sale in the normal course of business. During the year-ended December 31, 2019, we sold $432 million of AFS securities, which resulted in a gain of $7 million. Held-to-maturity securities Investment securities HTM are carried at amortized cost and adjusted for amortization of premiums and accretion of discounts using the interest method. Unrealized losses are not recorded to the extent they are temporary in nature. There were no purchases or sales of HTM securities during the years ended December 31, 2021, December 31, 2020 and December 31, 2019. The following table summarizes the unrealized loss positions on available-for-sale and held-to-maturity investment securities, by duration of the unrealized loss: Unrealized Loss Position with Duration Unrealized Loss Position with Duration Fair Number of Unrealized Fair Number of Unrealized (Dollars in millions) December 31, 2021 Available-for-sale securities Agency - Commercial $ 4 2 $ — $ 143 9 $ — Agency - Residential — — — 291 19 (3) Municipal obligations — — — 3 1 — Corporate debt obligations — — — — — — Other mortgage-backed securities — 1 — 147 5 (1) Held-to-maturity securities Agency - Commercial $ — — $ — $ — 1 $ — Agency - Residential — — — — — — December 31, 2020 Available-for-sale securities Agency - Commercial $ 3 1 $ — $ 7 2 $ — Agency - Residential — — — — 1 — Corporate debt obligations — — — 10 3 — Other mortgage-backed securities — — — — 1 — Held-to-maturity securities Agency - Residential — — — 2 3 — Unrealized losses on available-for-sale securities have not been recognized into income because almost all of the portfolio held by us are issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies, and have a long history of no credit losses. The remaining unrealized losses on available-for-sale securities are municipal securities and corporate debt obligations, all of which are considered investment grade or are de minimis. The fair value is expected to recover as the bonds approach maturity.

Commercial Loans Risk rating and the average loan duration have the most significant impact on the ACL for commercial loans. Additional factors which impact the ACL are debt-service-coverage ratio, loan-to-value ratio, interest-coverage ratio and leverage ratio. Internal audit conducts periodic examinations which serve as an independent verification of the accuracy of the ratings assigned. All loans are examined on at least an annual basis. Loan grades are based on different factors within the borrowing relationship: entity sales, debt service coverage, debt/total net worth, liquidity, balance sheet and income statement trends, management experience, business stability, financing structure and financial reporting requirements. The underlying collateral is also rated based on the specific type of collateral and corresponding LTV. The combination of the borrower and collateral risk ratings results in the final risk rating for the borrowing relationship. Based on the most recent credit analysis performed, the amortized cost basis, by risk category for each class of loans within the commercial portfolio, is as follows: Term Loans Revolving Loans Amortized Cost Basis Revolving Loans Converted to Term Loans Amortized Cost Basis Total December 31, 2020 Amortized Cost Basis by Closing Year As of December 31, 2021 2021 2020 2019 2018 2017 Prior Commercial Loans (Dollars in million) Commercial real estate Pass $ 518 $ 257 $ 558 $ 313 $ 238 $ 402 $ 785 $ — $ 3,071 $ 2,805 Watch 2 5 1 13 64 35 8 — 128 166 Special mention — — 2 — — — — — 2 53 Substandard — — — — 22 — — — 22 37 Commercial and industrial Pass 257 81 156 30 95 7 1,059 — 1,685 1,200 Watch 4 4 10 9 — — 44 — 71 106 Special mention — — — — — — — — — 24 Substandard — — 17 18 2 — 33 — 70 52 Warehouse Pass 4,834 — — — — — — — 4,834 7,398 Watch 140 — — — — — — — 140 260 Special mention — — — — — — — — — — Substandard — — — — — — — — — — Total commercial loans $ 5,755 $ 347 $ 744 $ 383 $ 421 $ 444 $ 1,929 $ — $ 10,023 $ 12,101 " id="sjs-B4" xml:space="preserve">Loans Held-for-Investment We classify loans that we have the intent and ability to hold for the foreseeable future or until maturity as LHFI.

We have pledged certain LHFI, LHFS, and LGG to collateralize lines of credit and/or borrowings with the FRB of Chicago and the FHLB of Indianapolis. At December 31, 2021 and 2020, we pledged loans of $9.9 billion and $11.6 billion, respectively. As of December 31, 2021, we utilized the Moody’s November 2021 economic scenarios in our forecast, which were materially consistent with the December scenarios: a growth forecast, weighted at 30 percent; a baseline forecast, weighted at 40 percent; and an adverse forecast, weighted at 30 percent. The resulting composite forecast for the fourth quarter of 2021 was improved as compared to the scenario used in the third quarter 2021. Unemployment ends 2021 at 5 percent and will continue to recover in 2022. GDP continues to recover in the last quarter of 2021 and returns to pre-COVID levels in 2023. HPI decreases slightly through 2022, at a lower rate as compared to the scenario used in the third quarter of 2021.

The ALLL was $154 million at December 31, 2021 and $252 million at December 31, 2020. The decrease in the allowance is primarily reflective of changes in our economic forecast and judgment we applied related to those forecasts and underlying borrower credit as a result of the ongoing COVID-19 pandemic. Loans are considered to be past due when any payment of principal or interest is 30 days past the scheduled payment date. While it is the goal of Management to collect on loans, we attempt to work out a satisfactory repayment schedule or modification with past due borrowers and will undertake foreclosure proceedings if the delinquency is not satisfactorily resolved. Our practices regarding past due loans are designed to both assist borrowers in meeting their contractual obligations and minimize losses incurred by the Bank. Beginning in March 2020, as a response to COVID-19, customers facing COVID-19 related difficulties were offered forbearance in an effort to help our borrowers get to the other side of the health crisis. As these loans reach the end of their forbearance period, we have been working with each customer to modify or refinance the outstanding loan to fit their new circumstances. We cease the accrual of interest on all classes of consumer and commercial loans upon the earlier of becoming 90 days past due, or when doubt exists as to the ultimate collection of principal or interest (classified as nonaccrual or NPLs). When a loan is placed on nonaccrual status, the accrued interest income is reversed and the loan may only return to accrual status when principal and interest become current and are anticipated to be fully collectible. We do not consider accrued interest receivable in our measurement of the ACL as accrued interest is written-off in a timely manner when the loan is placed on nonaccrual. We are not aging receivables for customers who have been granted a payment deferral in response to COVID-19 which remain in the aging category they were in at the time of payment deferral. We continue to accrue interest on these loans, consistent with our forbearance programs. The following table sets forth the LHFI aging analysis of past due and current loans: 30-59 Days 60-89 Days 90 Days or Total Current Total LHFI (3)(4)(5) (Dollars in millions) December 31, 2021 Consumer loans Residential first mortgage $ 14 $ 34 $ 49 $ 97 $ 1,439 $ 1,536 Home equity 8 1 9 18 595 613 Other 4 1 4 9 1,227 1,236 Total consumer loans 26 36 62 124 3,261 3,385 Commercial loans Commercial real estate — — — — 3,223 3,223 Commercial and industrial — — 32 32 1,794 1,826 Warehouse lending — — — — 4,974 4,974 Total commercial loans — — 32 32 9,991 10,023 Total loans (2) $ 26 $ 36 $ 94 $ 156 $ 13,252 $ 13,408 December 31, 2020 Consumer loans Residential first mortgage $ 4 $ 4 $ 31 $ 39 $ 2,227 $ 2,266 Home equity 1 1 5 7 849 856 Other 4 1 2 7 997 1,004 Total consumer loans 9 6 38 53 4,073 4,126 Commercial loans Commercial real estate 20 — 3 23 3,038 3,061 Commercial and industrial 1 — 15 16 1,366 1,382 Warehouse lending — — — — 7,658 7,658 Total commercial loans 21 — 18 39 12,062 12,101 Total loans (2) $ 30 $ 6 $ 56 $ 92 $ 16,135 $ 16,227 (1) Includes less than 90 days past due performing loans which are placed in nonaccrual. Interest is not being accrued on these loans. (2) Includes $9 million and $8 million of past due loans accounted for under the fair value option at December 31, 2021 and 2020, respectively. (3) Collateral dependent loans totaled $108 million and $80 million at December 31, 2021 and 2020, respectively. The majority of these loans are secured by real estate. (4) The interest income recognized on impaired loans was less than $1 million at December 31, 2021 and $2 million at December 31, 2020. (5) The delinquency status for loans in forbearance is frozen for loans at inception of the forbearance period and will resume when the borrower's forbearance period ends. Interest income is recognized on nonaccrual loans using a cash basis method. Interest that would have been accrued was $1 million in each of the years ended December 31, 2021, 2020 and 2019. At December 31, 2021 and 2020, we had no loans 90 days or greater past due and still accruing interest. Reserve for Unfunded Commitments The reserve for unfunded commitments is reflected in other liabilities on the Consolidated Statements of Financial Condition and was $16 million as of December 31, 2021, compared to $28 million as of December 31, 2020. The decrease in the reserve is due to improvements in the economic forecasts as a result of the continued vaccine rollout and the lifting of most COVID-19 restrictions. Troubled Debt Restructurings We may modify certain loans in both our consumer and commercial loan portfolios to retain customers or to maximize collection of the outstanding loan balance. Troubled debt restructurings ("TDRs") are modified loans in which a borrower demonstrates financial difficulties and for which a concession has been granted as a result. Nonperforming TDRs are included in nonaccrual loans. TDRs remain in nonperforming status until a borrower has made payments and is current for at least six consecutive months. Performing TDRs are not considered to be nonaccrual so long as we believe that all contractual principal and interest due under the restructured terms will be collected. Performing and nonperforming TDRs remain impaired as interest and principal will not be received in accordance with the original contractual terms of the loan agreement. Refer to Note 1- Description of Business, Basis of Presentation, and Summary of Significant Accounting Standards for a description of the methodology used to determine TDRs. Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, but may give rise to potential incremental losses. We measure impairments using a discounted cash flow method for performing TDRs and measure impairment based on collateral values for nonperforming TDRs. Beginning in March 2020, as a response to COVID-19, we offered our consumer borrowers principal and interest payment deferrals, forbearance and/or extensions up to a maximum period of 18 months. We considered these programs in the context of whether or not the short-term modifications of these loans would constitute a TDR. We considered the CARES Act, interagency guidance and related guidance from the FASB, which provided that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not required to be accounted for as TDRs. As a result, we have determined that loan forbearance, modifications, deferrals and extensions made under these COVID-19 programs are not TDRs. The following table provides a summary of TDRs by type and performing status: TDRs Performing Nonperforming Total (Dollars in millions) December 31, 2021 Consumer loans Residential first mortgage $ 14 $ 11 $ 25 Home equity 8 2 10 Total consumer TDRs loans (1)(2) $ 22 $ 13 $ 35 Commercial Loans Commercial and industrial 2 — 2 Total commercial TDR loans 2 — 2 Total TDRs (1)(2) $ 24 $ 13 $ 37 December 31, 2020 Consumer loans Residential first mortgage $ 19 $ 8 $ 27 Home equity 12 2 14 Total consumer TDR loans 31 10 41 Commercial Loans Commercial real estate 5 — 5 Total commercial TDR loans 5 — 5 Total TDRs (1)(2) $ 36 $ 10 $ 46 (1) The ALLL on TDR loans totaled $4 million and $5 million at December 31, 2021 and 2020, respectively.

(2) Home equity post-modification UPB reflects write downs. (3) Includes loans carried at fair value option. There were no loans modified in the previous 12 months that subsequently defaulted during the years ended December 31, 2021, 2020, and 2019. All TDR classes within the consumer and commercial loan portfolios are considered subsequently defaulted when they are greater than 90 days past due within 12 months of the restructuring date. Credit Quality We utilize a combination of internal and external risk rating systems which are applied to all consumer and commercial loans which are used as loan-level inputs to our ACL models. Descriptions of our risk ratings as they relate to credit quality follow the ratings used by the U.S. bank regulatory agencies as listed below. Pass. Pass assets are not impaired nor do they have any known deficiencies that could impact the quality of the asset. Watch. Watch assets are defined as pass-rated assets that exhibit elevated risk characteristics or other factors that deserve Management’s close attention and increased monitoring. However, the asset does not exhibit a potential or well-defined weakness that would warrant a downgrade to criticized or adverse classification. Special mention. Assets identified as special mention possess credit deficiencies or potential weaknesses deserving Management's close attention. Special mention assets have a potential weakness or pose an unwarranted financial risk that, if not corrected, could weaken the assets and increase risk in the future. Special mention assets are criticized, but do not expose an institution to sufficient risk to warrant adverse classification. Substandard . Assets identified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the full collection or liquidation of the debt. Substandard assets are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. For home equity loans and other consumer loans, we evaluate credit quality based on the aging and status of payment activity and any other known credit characteristics that call into question full repayment of the asset. Substandard loans may be placed on either accrual or nonaccrual status. Doubtful . An asset classified as doubtful has all the weaknesses inherent in one classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. A doubtful asset has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Due to the high probability of loss, doubtful assets are placed on nonaccrual. Loss. An asset classified as loss is considered uncollectible and of such little value that the continuance as a bankable asset is not warranted. This classification does not mean that an asset has absolutely no recovery or salvage value, rather that it is not practical or desirable to defer writing off the asset even though partial recovery may be affected in the future. Consumer Loans Consumer loans consist of open and closed-end loans extended to individuals for household, family, and other personal expenditures. Consumer loans include other consumer product loans and loans to individuals secured by their personal residence, including first mortgage, home equity, and home improvement loans. Because consumer loans are usually relatively small-balance, homogeneous exposures, consumer loans are rated based primarily on payment performance. Payment performance is a proxy for the strength of repayment capacity and loans are generally classified based on their payment status rather than by an individual review of each loan. In accordance with regulatory guidance, we assign risk ratings to consumer loans in the following manner: • Consumer loans are classified as Watch once the loan becomes 60 days past due. • Open and closed-end consumer loans 90 days or more past due are classified as Substandard. Payment activity, credit rating and loan-to-value ratios have the most significant impact on the ACL for consumer loans.

Commercial Loans Risk rating and the average loan duration have the most significant impact on the ACL for commercial loans. Additional factors which impact the ACL are debt-service-coverage ratio, loan-to-value ratio, interest-coverage ratio and leverage ratio. Internal audit conducts periodic examinations which serve as an independent verification of the accuracy of the ratings assigned. All loans are examined on at least an annual basis. Loan grades are based on different factors within the borrowing relationship: entity sales, debt service coverage, debt/total net worth, liquidity, balance sheet and income statement trends, management experience, business stability, financing structure and financial reporting requirements. The underlying collateral is also rated based on the specific type of collateral and corresponding LTV. The combination of the borrower and collateral risk ratings results in the final risk rating for the borrowing relationship. Based on the most recent credit analysis performed, the amortized cost basis, by risk category for each class of loans within the commercial portfolio, is as follows: Term Loans Revolving Loans Amortized Cost Basis Revolving Loans Converted to Term Loans Amortized Cost Basis Total December 31, 2020 Amortized Cost Basis by Closing Year As of December 31, 2021 2021 2020 2019 2018 2017 Prior Commercial Loans (Dollars in million) Commercial real estate Pass $ 518 $ 257 $ 558 $ 313 $ 238 $ 402 $ 785 $ — $ 3,071 $ 2,805 Watch 2 5 1 13 64 35 8 — 128 166 Special mention — — 2 — — — — — 2 53 Substandard — — — — 22 — — — 22 37 Commercial and industrial Pass 257 81 156 30 95 7 1,059 — 1,685 1,200 Watch 4 4 10 9 — — 44 — 71 106 Special mention — — — — — — — — — 24 Substandard — — 17 18 2 — 33 — 70 52 Warehouse Pass 4,834 — — — — — — — 4,834 7,398 Watch 140 — — — — — — — 140 260 Special mention — — — — — — — — — — Substandard — — — — — — — — — — Total commercial loans $ 5,755 $ 347 $ 744 $ 383 $ 421 $ 444 $ 1,929 $ — $ 10,023 $ 12,101

Loans with Government Guarantee

Loans and Leases Receivable Disclosure [Abstract]
Loans with Government Guarantees	Loans with Government Guarantees Substantially all LGG are insured or guaranteed by the FHA or the U.S. Department of Veterans Affairs. Nonperforming repurchased loans in this portfolio earn interest at a rate based upon the 10-year U.S. Treasury note rate from the time the underlying loan becomes 60 days delinquent until the loan is conveyed to HUD (if foreclosure timelines are met), which is not paid by the FHA until claimed. The Bank has a unilateral option to repurchase loans sold to GNMA if the loan is due, but unpaid, for three consecutive months (typically referred to as 90 days past due) and can recover losses through a claims process from the guarantor. These loans are recorded in LGG and the liability to repurchase the loans is recorded as loans with government guarantees repurchase liability on the Consolidated Statements of Financial Condition. This resulted in $0.2 billion of repurchase liability as of December 31, 2021, a $1.7 billion decrease from December 31, 2020 due to a lower amount of loans being in active forbearance. Certain loans within our portfolio may be subject to indemnifications and insurance limits which expose us to limited credit risk. We have reserved for these risks within other assets and as a component of our ACL on residential first mortgages. At December 31, 2021 and December 31, 2020, respectively, LGG totaled $1.7 billion and $2.5 billion. Repossessed assets and the associated claims related to government guaranteed loans are recorded in other assets and totaled $7 million and $17 million at December 31, 2021 and December 31, 2020, respectively.

Variable Interest Entities	Variable Interest Entities    We have no consolidated VIEs as of December 31, 2021 and December 31, 2020.     In connection with our non-qualified mortgage securitization activities, we have retained a five percent interest in the investment securities of certain trusts ("other MBS") and are contracted as the subservicer of the underlying loans, compensated based on market rates, which constitutes a continuing involvement in these trusts. Although we have a variable interest in these securitization trusts, we are not their primary beneficiary due to the relative size of our investment in comparison to the total amount of securities issued by the VIE and our inability to direct activities that most significantly impact the VIE’s economic performance. As a result, we have not consolidated the assets and liabilities of the VIE in our Consolidated Statements of Financial Condition. The Bank’s maximum exposure to loss is limited to our five percent retained interest in the investment securities that had a fair value of $267 million as of December 31, 2021 as well as the standard representations and warranties made in conjunction with the loan transfers.

Mortgage Servicing Rights

Mortgage Servicing Rights	12 Months Ended
	Dec. 31, 2021
Transfers and Servicing [Abstract]
Mortgage Servicing Rights	Mortgage Servicing Rights We have investments in MSRs that result from the sale of loans to the secondary market for which we retain the servicing. We account for MSRs at their fair value. A 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. We 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 default rates, which we do not believe can be effectively managed using derivatives. For further information regarding the derivative instruments utilized to manage our MSR risks, see Note 11 - Derivative Financial Instruments. Changes in the fair value of residential first mortgage MSRs were as follows: For the Years Ended December 31, 2021 2020 2019 (Dollars in millions) Balance at beginning of period $ 329 $ 291 $ 290 Additions from loans sold with servicing retained 269 268 223 Reductions from sales (164) (71) (57) Decrease in MSR fair value due to pay-offs, pay-downs, run-off, model changes, and other (1) (99) (109) (89) Changes in estimates of fair value due to interest rate risk (1) (2) 57 (50) (76) Fair value of MSRs at end of period $ 392 $ 329 $ 291 (1) Changes in fair value are included within net return on mortgage servicing rights on the Consolidated Statements of Operations. (2) Represents estimated MSR value change resulting primarily from market-driven changes which we manage through the use of derivatives. The following table summarizes the hypothetical effect on the fair value of servicing rights using adverse changes of 10 percent and 20 percent to the weighted average of certain significant assumptions used in valuing these assets: December 31, 2021 December 31, 2020 Fair value Fair value Actual 10% adverse change 20% adverse change Actual 10% adverse change 20% adverse change (Dollars in millions) Option adjusted spread 7.12 % $ 383 $ 374 7.98 % $ 321 $ 313 Constant prepayment rate 9.24 % 373 355 10.53 % 305 283 Weighted average cost to service per loan $ 79.38 387 383 $ 81.24 325 321 The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. To isolate the effect of the specified change, the fair value shock analysis is consistent with the identified adverse change, while holding all other assumptions constant. In practice, a change in one assumption generally impacts other assumptions, which may either magnify or counteract the effect of the change. For further information on the fair value of MSRs, see Note 1 - Description of Business, Basis of Presentation, and Summary of Significant Accounting Standards and Note 20 - Fair Value Measurements. Contractual servicing and subservicing fees . Contractual servicing and subservicing fees, including late fees and other ancillary income are presented below. Contractual servicing fees are included within net return on mortgage servicing rights on the Consolidated Statements of Operations. Contractual subservicing fees including late fees and other ancillary income are included within loan administration income on the Consolidated Statements of Operations. Subservicing fee income is recorded for fees earned on subserviced loans, net of third-party subservicing costs.

However, for derivative contracts cleared through certain central clearing parties, variation margin payments are recognized as settlements. We are exposed to non-performance risk by the counterparties to our various derivative financial instruments. A majority of our derivatives are centrally cleared through a Central Counterparty Clearing House or consist of residential mortgage interest rate lock commitments further limiting our exposure to non-performance risk. We believe that the non-performance risk inherent in our remaining derivative contracts is minimal based on credit standards and the collateral provisions of the derivative agreements. Derivatives not designated as hedging instruments. We maintain a derivative portfolio of interest rate swaps, futures and forward commitments used to manage exposure to changes in interest rates and MSR asset values and to meet the needs of customers. We also enter into interest rate lock commitments, which are commitments to originate mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. Market risk on interest rate lock commitments and mortgage LHFS is managed using corresponding forward sale commitments and US Treasury futures. Changes in the fair value of derivatives not designated as hedging instruments are recognized on the Consolidated Statements of Operations. Derivatives designated as hedging instruments. We have designated certain interest rate swaps as fair value hedges of investment securities available for sale and residential first mortgage loans held for investment using the last-of-layer method. Cash flows and the profit impact associated with designated hedges are reported in the same category as the underlying hedged item. We have also designated certain interest rate swaps as cash flow hedges on LIBOR-based variable interest payments on certain custodial deposits. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense in the same period in which the hedge transaction is recognized in earnings. At December 31, 2021, we had $20 million (net-of-tax) of unrealized gains on derivatives classified as cash flow hedges recorded in accumulated other comprehensive income. We had $5 million (net-of-tax) of unrealized losses on derivatives classified as cash flow hedges at December 31, 2020. The estimated amount to be reclassified from other comprehensive income into earnings during the next 12 months represents $1 million of losses (net-of-tax). Derivatives that are designated in hedging relationships are assessed for effectiveness using regression analysis at inception and qualitatively thereafter, unless regression analysis is deemed necessary. All designated hedge relationships were, and are expected to be, highly effective as of December 31, 2021.

Losses of $4 million and $2 million on cash flow hedging relationships of custodial deposits were reclassified from AOCI into loan administration income during the year-ended December 31, 2021 and December 31, 2020, respectively. Gains and losses on fair value hedging relationships of HFI residential first mortgages for the year-ended December 31, 2021 were de-minimis. The fair value basis adjustment on our hedged AFS securities is included in investment securities available for sale on our Consolidated Statements of Financial Condition. The carrying amount of our hedged securities was $1.0 billion at December 31, 2021 and $1.7 billion at December 31, 2020, of which unrealized losses of $5 million and unrealized gains of $6 million, respectively, were due to the fair value hedge relationship.

The fair value basis adjustment on our hedged fair HFI residential first mortgages is included in LHFI on our Consolidated Statements of Financial Condition. The carrying amount of our hedged loans was $175 million at December 31, 2021, of which unrealized losses of $1 million was due to the fair value hedge relationship. We have designated $100 million of this closed portfolio of loans in a hedging relationship as of December 31, 2021 and 2020. At December 31, 2021, we pledged a total of $66 million related to derivative financial instruments, consisting of $28 million of cash collateral on derivative liabilities and $38 million of maintenance margin on centrally cleared derivatives and had a $12 million obligation to return cash on derivative assets. We pledged a total of $114 million related to derivative financial instruments, consisting of $84 million of cash collateral on derivatives and $30 million of maintenance margin on centrally cleared derivatives and had a de minimis obligation to return cash on derivative assets at December 31, 2020.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share, excluding dilution, is computed by dividing earnings applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised and converted into common stock or resulted in the issuance of common stock that could then share in our earnings. The following table sets forth the computation of basic and diluted earnings per share of common stock: For the Years Ended December 31, 2021 2020 2019 (In millions, except share data) Net income applicable to common stockholders $ 533 $ 538 $ 218 Weighted Average Shares Weighted average common shares outstanding 52,792,931 56,094,542 56,584,238 Effect of dilutive securities Stock-based awards 726,155 411,271 654,740 Weighted average diluted common shares 53,519,086 56,505,813 57,238,978 Earnings per common share Basic earnings per common share $ 10.10 $ 9.59 $ 3.85 Effect of dilutive securities Stock-based awards (0.14) (0.07) (0.05) Diluted earnings per common share $ 9.96 $ 9.52 $ 3.80

Stock-Based Compensation	Stock-Based Compensation We had stock-based compensation expense of $14 million, $17 million, and $13 million during each of the years ended December 31, 2021, 2020 and 2019, respectively. Restricted Stock and Restricted Stock Units We have issued restricted stock units to officers, directors and certain employees under the 2016 Stock Plan through our long-term incentive program ("LTIP"). Restricted stock units generally will vest in three increments on each annual anniversary of the date of grant beginning with the first anniversary or vest after three years subject to service and performance conditions. On March 20, 2018, the Board approved the adoption of the 2018 Executive Long-Term Incentive Program II ("2018 ExLTIP II"). The 2018 ExLTIP II was provided to certain executives and is comprised of RSUs which are dependent on stock performance, time-based RSUs for which vesting is based on service over a four year period and RSUs that are performance and time vested with the same terms as those granted to other employees under the existing LTIP. As of December 31, 2021, the stock performance hurdles have been met and 94 percent of the shares had vested. At December 31, 2021, the maximum number of shares of common stock that may be issued under the 2016 Stock Plan was 1.4 million shares. The total grant date fair value of awards vested during the years ended December 31, 2021, 2020 and 2019 was $22 million, $15 million, and $10 million, respectively. As of December 31, 2021, the total unrecognized compensation cost related to non-vested awards was $14 million with a weighted average expense recognition period of 1.9 years.

Temporary differences and carryforwards that give rise to DTAs and liabilities are comprised of the following: December 31, 2021 2020 (Dollars in millions) Deferred tax assets Net operating loss carryforwards (Federal and State) $ 28 $ 36 Allowance for credit losses 28 58 Accrued compensation 16 15 Litigation settlement — 8 Lease liability 5 6 Contingent consideration 8 7 General business reserves — 11 Other 10 4 Total $ 95 $ 145 Valuation allowance (5) (7) Total net $ 90 $ 138 Deferred tax liabilities Mark-to-market adjustments $ (6) $ (4) Premises and equipment (15) (7) State and local taxes (3) (6) Commercial lease financing (1) (1) Mortgage loan servicing rights (72) (53) Right of use asset (5) (5) Total $ (102) $ (76) Net deferred tax (liability) asset $ (12) $ 62 We have not provided deferred income taxes for the Bank’s pre-1988 tax bad debt reserve at December 31, 2021, of approximately $4 million because it is not anticipated that this temporary difference will reverse in the foreseeable future. Such reserves would only be taken into taxable income if the Bank, or a successor institution, liquidates, redeems shares, pays dividends in excess of earnings, or ceases to qualify as a bank for tax purposes. During the years ended December 31, 2021 and 2020, we had federal net operating loss carryforwards of $33 million and $51 million, respectively. These carryforwards, if unused, expire in calendar years 2028 through 2029. As a result of a change in control occurring on January 30, 2009 and November 10, 2020, Section 382 of the Internal Revenue Code places an annual limitation on the use of our new operating loss carryforwards that existed at those times. $33 million of net operating loss carryforwards are subject to certain annual use limitations which expire in calendar years 2028 through 2029. We regularly evaluate the need for DTA valuation allowances based on a more likely than not standard as defined by GAAP. The ability to realize DTAs depends on the ability to generate sufficient taxable income within the carryback or carryforward periods provided for in the tax law for each applicable tax jurisdiction. We had a state DTA of $19 million which includes total state net operating loss carryforwards of $316 million at December 31, 2021, that expire if unused in calendar years through 2033. In connection with our ongoing assessment of deferred taxes, we analyzed each state net operating loss separately, determined the amount of net operating loss available and estimated the amount which we expected to expire unused. Based on that assessment, we recorded a valuation allowance of $5 million to reduce the DTA for state net operating losses to the amount which is more likely than not to be realized. We will continue to regularly assess the realizability of our DTAs. Changes in earnings performance and future earnings projections, among other factors, may cause us to adjust our valuation allowance. Our income tax returns are subject to review and examination by federal, state and local government authorities. On an ongoing basis, numerous federal, state and local examinations are in progress and cover multiple tax years. At December 31, 2021, the Internal Revenue Service had completed an examination of us through the taxable year-ended December 31, 2013. The years open to examination by state and local government authorities vary by jurisdiction.

Regulatory Capital

Banking and Thrift, Other Disclosures [Abstract]
Regulatory Capital	Regulatory Capital We, along with the Bank, are subject to the Basel III based U.S. capital rules, including capital simplification in 2020. Under these requirements, we must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional, discretionary actions by regulators that could have a material effect on the Consolidated Financial Statements. To be categorized as "well-capitalized," the Company and the Bank must maintain minimum tangible capital, Tier 1 capital, common equity Tier 1 and total capital ratios as set forth in the table below. We, along with the Bank, are considered "well-capitalized" at both December 31, 2021 and December 31, 2020.

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings, Contingencies and Commitments	Legal Proceedings, Contingencies and Commitments Legal Proceedings We and our subsidiaries are subject to various pending or threatened legal proceedings arising out of the normal course of business operations. In addition, the Bank is routinely named in civil actions throughout the country by borrowers and former borrowers relating to the closing, purchase, sale and servicing of mortgage loans. From time to time, governmental agencies also conduct investigations or examinations of various practices of the Bank. In the course of such investigations or examinations, the Bank cooperates with such agencies and provides information as requested. We assess the liabilities and loss contingencies in connection with pending or threatened legal and regulatory proceedings on at least a quarterly basis and establish accruals when we believe it is probable that a loss may be incurred and that the amount of such loss can be reasonably estimated. Once established, litigation accruals are adjusted, as appropriate, in light of additional information. Payments made to settle our liabilities may differ from the contingency or fair value recorded due to factors that differ from our assumptions. At December 31, 2021, we do not believe that the amount of any reasonably possible losses in excess of any amounts accrued with respect to ongoing proceedings or any other known claims will be material to our financial statements or that the ultimate outcome of these actions will have a materially adverse effect on our financial condition, results of operations or cash flows. DOJ Liability On February 24, 2012, the Bank entered into a Settlement Agreement with the DOJ under which we agreed to make future payments totaling $118 million in annual increments of up to $25 million upon meeting certain conditions. On March 30, 2021, the Bank signed a $70 million final Settlement and Dismissal Amendment (the "Amendment") with the DOJ. The Amendment required us to make a $70 million one-time restitution cash payment and removed any further obligations related to the original Settlement Agreement. We recorded a $35 million expense to adjust the fair value of the DOJ Liability through general, administrative and other noninterest expense in the first quarter of 2021. The payment was made on April 8, 2021, fully satisfying the Amendment and reducing the liability to $0. For further information on the fair value of the liability, see Note 20 - Fair Value Measurements. Other litigation accruals At December 31, 2021 and December 31, 2020, excluding the fair value liability relating to the DOJ Liability, our total accrual for contingent liabilities and settled litigation was $9 million and $7 million, respectively. Commitments In the normal course of business, we have various commitments outstanding which are not included on our Consolidated Statements of Financial Condition. The following table is a summary of the contractual amount of significant commitments: December 31, 2021 2020 (Dollars in millions) Commitments to extend credit Warehouse loan commitments $ 6,840 $ 2,849 Mortgage loan commitments including interest rate locks 5,539 10,702 Other construction commitments 2,719 1,934 Commercial and industrial commitments 1,582 1,271 HELOC commitments 631 544 Other consumer commitments 273 121 Standby and commercial letters of credit 107 95 Commitments to extend credit are agreements to lend to a customer as long as there is not a violation of any condition established in the contract. Because many of these commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements. Commitments generally have fixed expiration dates or other termination clauses. We evaluate each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by us, upon extension of credit is based on Management's credit evaluation of the counterparties. These instruments involve, to varying degrees, elements of credit and interest rate risk beyond the amount recognized on the Consolidated Statements of Financial Condition. Our exposure to credit losses in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. We utilize the same credit policies in making commitments and conditional obligations as we do for balance sheet instruments. The types of credit we extend are as follows: Mortgage loan commitments including interest rate locks. We enter into mortgage loan commitments, including interest rate locks with our customers. These interest rate lock commitments are considered to be derivative instruments and the fair value of these commitments is recorded on the Consolidated Statements of Financial Condition in other assets. For further information, see Note 11 - Derivative Financial Instruments. Warehouse loan commitments. Lines of credit provided to mortgage originators to fund loans they originate and then sell. The proceeds of the sale of the loans are used to repay the draw on the line used to fund the loans. Commercial and industrial and other construction commitments. Conditional commitments issued under various terms to lend funds to businesses and other entities. These commitments include revolving credit agreements, term loan commitments and short-term borrowing agreements. Many of these loan commitments have fixed expiration dates or other termination clauses and may require payment of a fee. Because many of these commitments are expected to expire without being funded, the total commitment amounts do not necessarily represent future liquidity requirements. HELOC commitments. Commitments to extend, originate or purchase credit are primarily lines of credit to consumers and have specified rates and maturity dates. Many of these commitments also have adverse change clauses, which allow us to cancel the commitment due to deterioration in the borrowers’ creditworthiness or a decline in the collateral value. Other consumer commitments. Conditional commitments issued to accommodate the financial needs of customers. The commitments are made under various terms to lend funds to consumers, which include revolving credit agreements, term loan commitments and short-term borrowing agreements. Standby and commercial letters of credit. Conditional commitments issued to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party, while commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and the third party. These financial standby letters of credit irrevocably obligate the bank to pay a third-party beneficiary when a customer fails to repay an outstanding loan or debt instrument. We maintain a reserve for estimated lifetime credit losses in unfunded commitments to extend credit. Unfunded commitments to extend credit include unfunded loans with available balances, new commitments to lend that are not yet funded and standby and commercial letters of credit. A reserve balance of $16 million at December 31, 2021 and $28 million at December 31, 2020, respectively, is reflected in other liabilities on the Consolidated Statements of Financial Condition. Supplemental executive retirement plan with former CEO. The Company entered into a supplemental executive retirement plan (“SERP”) with a former CEO in 2009. Under the plan, the former CEO was to receive a $16 million payment in August 2018. The Company fully accrued for the SERP liability during that time period and no SERP payments have been made to the former CEO. In the second quarter of 2021, we entered into a settlement agreement with the former CEO that terminates the SERP and all other prior employment agreements in exchange for a maximum payment of $6 million which remains subject to regulatory approval as of December 31, 2021.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We utilize fair value measurements to record or disclose the fair value on certain assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability through an orderly transaction between market participants at the measurement date. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation models rely on market-based parameters when available, such as interest rate yield curves or credit spreads. Unobservable inputs may be based on Management's judgment, assumptions and estimates related to credit quality, our future earnings, interest rates and other relevant inputs. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. Valuation Hierarchy U.S. GAAP establishes a three-level valuation hierarchy for disclosure of fair value measurements. The hierarchy is based on the transparency of the inputs used in the valuation process with the highest priority given to quoted prices available in active markets and the lowest priority given to unobservable inputs where no active market exists, as discussed below: Level 1 - Quoted prices (unadjusted) for identical assets or liabilities in active markets in which we can participate as of the measurement date, Level 2 - Quoted prices for similar instruments in active markets and other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument, and Level 3 - Unobservable inputs that reflect our own assumptions about the assumptions that market participants would use in pricing an asset or liability. A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input within the valuation hierarchy that is significant to the overall fair value measurement. Transfers between levels of the fair value hierarchy are recognized at the end of the reporting period. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables present the financial instruments carried at fair value by caption on the Consolidated Statements of Financial Condition and by level in the valuation hierarchy: December 31, 2021 Level 1 Level 2 Level 3 Total Fair Value (Dollars in millions) Loans held-for-sale Residential first mortgage loans $ — $ 4,920 $ — $ 4,920 Investment securities available-for-sale Agency - Commercial — 747 — 747 Agency - Residential — 696 — 696 Other MBS — 267 — 267 Corporate debt obligations — 73 — 73 Municipal obligations — 20 — 20 Certificate of deposit — 1 — 1 Derivative assets Interest rate swaps and swaptions — 77 — 77 Rate lock commitments (fallout-adjusted) — — 54 54 Mortgage-backed securities forwards — 10 — 10 Loans held-for-investment Residential first mortgage loans — 15 — 15 Home equity — — 1 1 Mortgage servicing rights — — 392 392 Total assets at fair value $ — $ 6,826 $ 447 $ 7,273 Derivative liabilities Mortgage-backed securities forwards — (14) — (14) Interest rate swaps and swaptions — (5) — (5) Rate lock commitments (fallout-adjusted) — — (1) (1) DOJ Liability — — — — Total liabilities at fair value $ — $ (19) $ (1) $ (20) December 31, 2020 Level 1 Level 2 Level 3 Total Fair Value (Dollars in millions) Investment securities available-for-sale Agency - Commercial $ — $ 1,061 $ — $ 1,061 Agency - Residential — 735 — 735 Municipal obligations — 28 — 28 Corporate debt obligations — 77 — 77 Other MBS — 42 — 42 Certificate of deposit — 1 — 1 Loans held-for-sale Residential first mortgage loans — 7,009 — 7,009 Loans held-for-investment Residential first mortgage loans — 11 — 11 Home equity — — 2 2 Mortgage servicing rights — — 329 329 Derivative assets Rate lock commitments (fallout-adjusted) — — 208 208 Mortgage-backed securities forwards — 14 — 14 Interest rate swaps and swaptions — 59 — 59 Total assets at fair value $ — $ 9,037 $ 539 $ 9,576 Derivative liabilities Mortgage-backed securities forwards — (98) — (98) Interest rate swaps and swaptions — (4) — (4) DOJ Liability — — (35) (35) Total liabilities at fair value $ — $ (102) $ (35) $ (137) Fair Value Measurements Using Significant Unobservable Inputs The following tables include a roll forward of the Consolidated Statements of Financial Condition amounts (including the change in fair value) for financial instruments classified by us within Level 3 of the valuation hierarchy: Balance at Total Gains / Purchases / Originations Sales Settlement Transfers In (Out) Balance at End of Year (Dollars in millions) Year-Ended December 31, 2021 Assets Loans held-for-investment Home equity $ 2 $ — $ — $ — $ (1) $ — $ 1 Mortgage servicing rights (1) 329 (42) 269 (164) — — 392 Rate lock commitments (net) (1)(2) 208 (100) 607 — — (661) 54 Totals $ 539 $ (142) $ 876 $ (164) $ (1) $ (661) $ 447 Liabilities DOJ Liability $ (35) $ (35) $ — $ — $ 70 $ — $ — Year-Ended December 31, 2020 Assets Loans held-for-investment Home equity $ 2 $ — $ — $ — $ — $ — $ 2 Mortgage servicing rights (1) 291 (159) 268 (71) — — 329 Rate lock commitments (net) (1)(2) 34 358 1,005 — — (1,189) 208 Totals $ 327 $ 199 $ 1,273 $ (71) $ — $ (1,189) $ 539 Liabilities DOJ Liability $ (35) $ — $ — $ — $ — $ — $ (35) Contingent consideration (10) (17) — — 27 — — Totals $ (45) $ (17) $ — $ — $ 27 $ — $ (35) Year-Ended December 31, 2019 Assets Loans held-for-investment Home equity $ 2 $ — $ — $ — $ — $ — $ 2 Mortgage servicing rights (1) 290 (165) 223 (57) — — 291 Rate lock commitments (net) (1)(2) 20 86 326 — — (398) 34 Totals $ 312 $ (79) $ 549 $ (57) $ — $ (398) $ 327 Liabilities DOJ Liability $ (60) $ 25 $ — $ — $ — $ — $ (35) Contingent consideration (6) (7) — — 3 — (10) Totals $ (66) $ 18 $ — $ — $ 3 $ — $ (45) (1) We utilized swaptions, futures, forward agency and loan sales and interest rate swaps to manage the risk associated with mortgage servicing rights and rate lock commitments. Gains and losses for individual lines do not reflect the effect of our risk management activities related to such Level 3 instruments. (2) Rate lock commitments are reported on a fallout-adjusted basis. Transfers out of Level 3 represent the settlement value of the commitments that are transferred to LHFS, which are classified as Level 2 assets. The following tables present the quantitative information about recurring Level 3 fair value financial instruments and the fair value measurements as of: Fair Value Valuation Technique Unobservable Input Range (Weighted Average) (Dollars in millions) December 31, 2021 Assets Loans held-for-investment Mortgage servicing rights $ 392 Discounted cash flows Option adjusted spread 3.9% - 21.6% (7.1%) 0% - 11.1% (9.2%) $67 - $90 ($80) (1) Rate lock commitments (net) $ 53 Consensus pricing Origination pull-through rate 72.8% (1) Fair Value Valuation Technique Unobservable Input Range (Weighted Average) (Dollars in millions) December 31, 2020 Assets Loans held-for-investment Home equity $ 2 Discounted cash flows Discount rate 7.2% -10.8% (9.0%) 12.6% - 18.9% (15.8%) 1.5%-2.3% (1.9%) (1) Mortgage servicing rights $ 329 Discounted cash flows Option adjusted spread 3.4% - 21.2% (8.0%) 0% - 13.3% (10.5%) $67 - $95 ($81) (1) Rate lock commitments (net) $ 208 Consensus pricing Closing pull-through rate 75.7% - 87.2% (77.5%) (1) Liabilities DOJ Liability $ (35) Discounted cash flows See description below See description below (1) Unobservable inputs were weighted by their relative fair value of the instruments. (2) Unobservable inputs were not weighted as only one instrument exists. Recurring Significant Unobservable Inputs Home equity. The most significant unobservable inputs used in the fair value measurement of the home equity loans are discount rates, constant prepayment rates and default rates. The constant prepayment and default rates are based on a 12 month historical average. Significant increases (decreases) in the discount rate in isolation result in a significantly lower (higher) fair value measurement. Increases (decreases) in prepay rates in isolation result in a higher (lower) fair value and increases (decreases) in default rates in isolation result in a lower (higher) fair value. MSRs. The significant unobservable inputs used in the fair value measurement of the MSRs are option adjusted spreads, prepayment rates and cost to service. Significant increases (decreases) in all three assumptions in isolation result in a significantly lower (higher) fair value measurement. Weighted average life (in years) is used to determine the change in fair value of MSRs. For December 31, 2021 and December 31, 2020, the weighted average life (in years) for the entire MSR portfolio was 5.8 and 4.2, respectively. DOJ Liability. The DOJ liability was settled for $70 million in the second quarter of 2021, fully satisfying the Amendment and reducing the liability to $0 at December 30, 2021. Prior to settlement, the significant unobservable inputs used in the fair value measurement of the DOJ Liability were the discount rate, asset growth rate, return on assets, dividend rate and potential ways we might be required to begin making DOJ Liability payments and our estimates of the likelihood of these outcomes, as further discussed in Note 19 - Legal Proceedings, Contingencies and Commitments. Rate lock commitments. The significant unobservable input used in the fair value measurement of the rate lock commitments is the pull through rate. The pull through rate is a statistical analysis of our actual rate lock fallout history to determine the sensitivity of the residential mortgage loan pipeline compared to interest rate changes and other deterministic values. New market prices are applied based on updated loan characteristics and new fallout ratios (i.e. the inverse of the pull through rate) are applied accordingly. Significant increases (decreases) in the pull through rate in isolation result in a significantly higher (lower) fair value measurement. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis We also have assets that are subject to measurement at fair value on a nonrecurring basis under certain conditions. The following table presents assets measured at fair value on a nonrecurring basis: Total (1) Level 2 Level 3 Gains/(Losses) (Dollars in millions) December 31, 2021 Loans held-for-sale (2) $ 116 $ 116 $ — $ (1) Commercial loans HFS 18 — 18 — Impaired loans held-for-investment (2) Residential first mortgage loans 36 — 36 (5) Repossessed assets (3) 6 — 6 (1) Totals $ 176 $ 116 $ 60 $ (7) December 31, 2020 Residential first mortgage loans $ 30 $ 30 $ — $ (1) Commercial loans HFS 57 — 57 — Impaired loans held-for-investment (2) Residential first mortgage loans 24 — 24 (3) Repossessed assets (3) 8 — 8 (3) Totals $ 119 $ 30 $ 89 $ (7) (1) The fair values are determined at various dates dependent upon when certain conditions were met requiring fair value measurement. (2) Gains/(losses) reflect fair value adjustments on assets for which we did not elect the fair value option. (3) Gains/(losses) reflect write downs of repossessed assets based on the estimated fair value of the specific assets. The following table presents the quantitative information about nonrecurring Level 3 fair value financial instruments and the fair value measurements: Fair Value Valuation Technique Unobservable Input Range (Weighted Average) (Dollars in millions) December 31, 2021 Impaired loans held-for-sale Commercial loans HFS $ 18 Fair value of collateral Market price N/A (2) Impaired loans held-for-investment Residential first mortgage loans $ 36 Fair value of collateral Loss severity discount 0% - 100% (12.7%) -2 Repossessed assets $ 6 Fair value of collateral Loss severity discount 0% - 96.3% (19.8%) -2 December 31, 2020 Commercial loans HFS $ 57 Fair value of collateral Market price N/A (2) Impaired loans held-for-investment Residential first mortgage loans $ 24 Fair value of collateral Loss severity discount 0% - 100% (12.8%) (1) Repossessed assets $ 8 Fair value of collateral Loss severity discount 0% - 96.3% (24.5%) (1) (1) Unobservable inputs were weighted by their relative fair value of the instruments. (2) Fair value has been determined based on an unobservable market price. Nonrecurring Significant Unobservable Inputs The significant unobservable inputs used in the fair value measurement of the impaired loans and repossessed assets are appraisals or other third-party price evaluations which incorporate measures such as recent sales prices for comparable properties. Fair Value of Financial Instruments The following table presents the carrying amount and estimated fair value of financial instruments that are carried either at fair value, cost or amortized cost: December 31, 2021 Estimated Fair Value Carrying Value Total Level 1 Level 2 Level 3 (Dollars in millions) Assets Cash and cash equivalents $ 1,051 $ 1,051 $ 1,051 $ — $ — Investment securities available-for-sale 1,804 1,804 — 1,804 — Investment securities held-to-maturity 205 209 — 209 — Loans held-for-sale 5,054 5,054 — 5,054 — Loans held-for-investment 13,408 13,453 — 14 13,439 Loans with government guarantees 1,650 1,650 — 1,650 — Mortgage servicing rights 392 392 — — 392 Federal Home Loan Bank stock 377 377 — 377 — Bank owned life insurance 365 365 — 365 — Repossessed assets 6 6 — — 6 Other assets, foreclosure claims 7 7 — 7 — Derivative financial instruments, assets 141 141 — 87 54 Liabilities Retail deposits Demand deposits and savings accounts $ (9,313) $ (8,469) $ — $ (8,469) $ — Certificates of deposit (951) (952) — (952) — Wholesale deposits (1,141) (1,137) — (1,137) — Government deposits (2,000) (1,904) — (1,904) — Company controlled deposits (4,604) (4,580) — (4,580) — Federal Home Loan Bank advances and other (3,280) (3,288) — (3,288) — Long-term debt (396) (340) — (340) — Derivative financial instruments, liabilities (20) (20) — (19) (1) December 31, 2020 Estimated Fair Value Carrying Value Total Level 1 Level 2 Level 3 (Dollars in millions) Assets Cash and cash equivalents $ 623 $ 623 $ 623 $ — $ — Investment securities available-for-sale 1,944 1,944 — 1,944 — Investment securities held-to-maturity 377 393 — 393 — Loans held-for-sale 7,098 7,098 — 7,098 — Loans held-for-investment 16,227 16,188 — 11 16,177 Loans with government guarantees 2,516 2,498 — 2,498 — Mortgage servicing rights 329 329 — — 329 Federal Home Loan Bank stock 377 377 — 377 — Bank owned life insurance 356 358 — 358 — Repossessed assets 8 8 — — 8 Other assets, foreclosure claims 17 17 — 17 — Derivative financial instruments 281 281 — 73 208 Liabilities Retail deposits Demand deposits and savings accounts $ (8,616) $ (7,864) $ — $ (7,864) $ — Certificates of deposit (1,355) (1,365) — (1,365) — Wholesale deposits (1,031) (1,047) — (1,047) — Government deposits (1,765) (1,706) — (1,706) — Custodial deposits (7,206) (7,133) — (7,133) — Federal Home Loan Bank advances (5,100) (5,124) — (5,124) — Long-term debt (641) (596) — (596) — DOJ litigation settlement (35) (35) — — (35) Contingent consideration — — — — — Derivative financial instruments (102) (102) — (102) — Fair Value Option We elected the fair value option for certain items as discussed throughout the Notes to the Consolidated Financial Statements to more closely align the accounting method with the underlying economic exposure.

Segment Information

Segment Information	12 Months Ended
	Dec. 31, 2021
Segment Reporting [Abstract]
Segment Information	Segment Information Our operations are conducted through three operating segments: Community Banking, Mortgage Originations and Mortgage Servicing. The Other segment includes the remaining reported activities. Operating segments are defined as components of an enterprise that engage in business activity from which revenues are earned and expenses are incurred for which discrete financial information is available that is evaluated regularly by executive management in deciding how to allocate resources and in assessing performance. The operating segments have been determined based on the products and services offered and reflect the manner in which financial information is currently evaluated by Management. Each segment operates under the same banking charter, but is reported on a segmented basis for this report. Each of the operating segments is complementary to each other and because of the interrelationships of the segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. The Community Banking segment originates loans, provides deposits and fee-based services to consumer, business, and mortgage lending customers through its Branch Banking, Business Banking and Commercial Banking, Government Banking and Warehouse Lending. Products offered through these groups include checking accounts, savings accounts, money market accounts, CD, consumer loans, commercial loans, CRE loans, home builder finance loans and warehouse lines of credit. Other financial services available include consumer and corporate card services, customized treasury management solutions, merchant services and capital markets services such as loan syndications, and investment and insurance products and services. The interest income on LHFI is recognized in the Community Banking segment, excluding residential first mortgages and newly originated home equity products within the Mortgage Originations segment. The Mortgage Originations segment originates and acquires one-to-four family residential mortgage loans to sell or hold on our balance sheet. Loans originated-to-sell comprise the majority of the lending activity. These loans are originated through mortgage branches, call centers, the Internet and third-party counterparties. The Mortgage Originations segment recognizes interest income on loans that are held-for-sale and the gains from sales associated with these loans, along with the interest income on residential mortgages and newly originated home equity products within LHFI. The Mortgage Servicing segment services and subservices mortgage and other consumer loans for others on a fee for service basis and may also collect ancillary fees and earn income through the use of noninterest-bearing escrows. Revenue for those serviced and subserviced loans is earned on a contractual fee basis, with the fees varying based on our responsibilities and the status of the underlying loans. The Mortgage Servicing segment also services loans for our LHFI portfolio and our own LHFS portfolio in the Mortgage Originations segment, for which it earns revenue via an intercompany service fee allocation. The Other segment includes the treasury functions, which include the impact of interest rate risk management, balance sheet funding activities and the administration of the investment securities portfolios, as well as miscellaneous other expenses of a corporate nature. In addition, the Other segment includes revenue and expenses related to treasury and corporate assets and liabilities and equity not directly assigned or allocated to the Community Banking, Mortgage Originations or Mortgage Servicing operating segments. Revenues are comprised of net interest income (before the provision (benefit) for credit losses) and noninterest income. Noninterest expenses and a majority of provision (benefit) for income taxes, are allocated to each operating segment. Provision for credit losses is allocated to segments based on net charge-offs and changes in outstanding balances. In contrast, the level of the consolidated provision for credit losses is determined based on an allowance model using the methodologies described in Item 2 – MD&A. The net effect of the credit provision is recorded in the Other segment. Allocation methodologies may be subject to periodic adjustment as the internal management accounting system is revised and the business or product lines within the segments change.

Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation and Basis of Presentation	Consolidation and Basis of Presentation    Our accounting and financial reporting policies conform to accounting principles generally accepted in the United States. Additionally, where applicable the policies conform to the accounting and reporting guidelines prescribed by regulatory authorities. Certain prior period amounts have been reclassified to conform to the current period presentation. The preparation of the Consolidated Financial Statements, requires Management to make estimates and assumptions that affect reported amounts of assets and liabilities, revenues and expenses and disclosures of contingent assets and liabilities. Actual results could be materially different from these estimates.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents include cash on hand, amounts due from correspondent banks and the FRB, and short-term investments that have a maturity at the date of acquisition of three months or less and are readily convertible to cash. Restricted cash includes cash that the Bank pledges as maintenance margin on centrally cleared derivatives and is included in other assets on the Consolidated Statements of Financial Condition.
Investment Securities	Investment Securities We measure securities classified as AFS at fair value, with unrealized gains and losses, net of tax, included in other comprehensive income (loss) in stockholders’ equity. We recognize realized gains and losses on AFS securities when securities are sold. The cost of securities sold is based on the specific identification method. Any gains or losses realized upon the sale of a security are reported in other noninterest income in the Consolidated Statements of Operations. The fair value of investment securities is based on observable market prices, when available. If observable market prices are not available, our valuations are based on alternative methods, including: quotes for similar fixed-income securities, matrix pricing, or discounted cash flow methods. Fair values are obtained through an independent third party utilizing a pricing service and are compared to independent pricing sources on a quarterly basis. For further information, see Note 2 - Investment Securities and Note 20 - Fair Value Measurements. Investment securities HTM are carried at amortized cost and are adjusted for the amortization of premiums and accretion of discounts using the interest method. Transfers of investment securities into the HTM category from the AFS category are accounted for at fair value at the date of transfer. Any related unrealized holding gain (loss), net of tax, that was included in the transfer is retained in other comprehensive income (loss) and is amortized as an adjustment to interest income over the remaining life of the securities. We separately evaluate our HTM debt securities for any credit losses. For each of the years in the three-year period ended December 31, 2021, all of our investment securities HTM were issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses; therefore, we apply a zero credit loss assumption to this portfolio and did not record any credit allowance for each of the three years ended December 31, 2021. We evaluate AFS debt securities where the value has declined below amortized cost for impairment. If we intend to sell or believe it is more likely than not that we will be required to sell the debt security, it is written down to fair value through earnings. For AFS debt securities we intend to hold, we evaluate the debt securities for expected credit losses, except for debt securities that are guaranteed by the U.S. Treasury, U.S. government agencies or sovereign entities of high credit quality for which we apply a zero loss assumption and comprised 82 percent of our AFS portfolio at December 31, 2021. For the remaining AFS securities, any decline in fair value that is related to market factors is recognized in OCI and credit losses are recognized as an increase to the ACL through the credit loss provision. For each of the years in the three-year period ended December 31, 2021, we had no unrealized credit losses.
Loans Held-for-Sale	Loans Held-for-Sale We classify loans as LHFS when we originate or purchase loans that we intend to sell. We have elected the fair value option for the majority of our LHFS. We estimate the fair value of mortgage loans based on quoted market prices for securities backed by similar types of loans, where available, or by discounting estimated cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. Changes in fair value are recorded to other noninterest income on the Consolidated Statements of Operations. LHFS that are recorded at lower of cost or fair value may be carried at fair value on a nonrecurring basis when the fair value is less than cost. For further information, see Note 20 - Fair Value Measurements. Loans that are transferred into the LHFS portfolio from the LHFI portfolio, due to a change in intent, are recorded at the lower of cost or fair value. Gains or losses recognized upon the sale of loans are determined using the specific identification method.
Loans Held-for-Investment	Loans Held-for-Investment We classify loans that we have the intent and ability to hold for the foreseeable future or until maturity as LHFI. Loans held-for-investment are reported at their amortized cost, which includes the outstanding principal balance adjusted for any unamortized premiums, discounts, deferred fees and costs. Accrued interest receivable on loans held-for-for investment totaled $35 million at December 31, 2021 and was reported in Other assets on the Consolidated Statements of Financial Condition. Premiums and discounts on purchased loans and non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, are deferred and recognized over the life of the related loans as an adjustment to the loans’ effective yield, which is included in interest income on loans in the Consolidated Statements of Operations. Loans originally classified as LHFS, for which we have elected the fair value option, and subsequently transferred to LHFI continue to be measured and reported at fair value on a recurring basis. Changes in fair value are recorded to other noninterest income on the Consolidated Statements of Operations. The fair value of these loans is determined using the same methods described above for LHFS. For further information, see Note 20 - Fair Value Measurements. When loans originally classified as LHFS or as LHFI are reclassified due to a change in intent or ability to hold, cash flows associated with the loans are classified in the Consolidated Statements of Cash Flows as operating or investing, in accordance with the initial classification of the loans.
Past Due, Impaired and Modified (Troubled Debt Restructuring) Loans	Past Due, Impaired and Modified (Troubled Debt Restructuring) Loans Loans are considered to be past due when any payment of principal or interest is 30 days past the scheduled payment date. While it is the goal of Management to collect on loans, we attempt to work out a satisfactory repayment schedule or modification with past due borrowers and will undertake foreclosure proceedings if the delinquency is not satisfactorily resolved. Our practices regarding past due loans are designed to both assist borrowers in meeting their contractual obligations and minimize losses incurred by the bank. We cease the accrual of interest on all classes of consumer and commercial loans upon the earlier of, becoming 90 days past due, or when doubt exists as to the ultimate collection of principal or interest (classified as nonaccrual or NPLs). When a loan is placed on nonaccrual status, the accrued interest income is reversed against interest income and the loan may only return to accrual status when principal and interest become current and are anticipated to be fully collectible. We do not measure an ACL for accrued interest receivables as accrued interest is written off in a timely manner. Loans are considered impaired if it is probable that payment of all interest and principal will not be made in accordance with the original contractual terms of the loan agreement or when any portion of principal or interest is 90 days past due. This classification includes both performing and nonperforming modified loans. For further information, see Note 4 - Loans Held-for-Investment. When a loan is considered impaired, the accrual of interest income is discontinued until the receipt of principal and interest is no longer in doubt. Interest income is recognized on impaired loans using a cost recovery method unless amounts contractually due are not in doubt. Cash received on nonperforming impaired loans is applied entirely against principal until the loan has been collected in full, after which time any additional cash receipts are recognized as interest income.
Loan Modifications (Troubled Debt Restructurings)	Loan Modifications (Troubled Debt Restructurings) We may modify certain loans in both our consumer and commercial loan portfolios to retain customers or to maximize collection of the outstanding loan balance. We have programs designed to assist borrowers by extending payment dates or reducing the borrower's contractual payments. All loan modifications are made on a case-by-case basis. Our standards relating to loan modifications consider, among other factors, minimum verified income requirements, cash flow analysis and collateral valuations. TDRs result in those instances in which a borrower demonstrates financial difficulty and for which a concession has been granted, including reductions of interest rates, extensions of amortization periods, principal and/or interest forgiveness and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral. These loans are classified as nonperforming TDRs if the loan was nonperforming prior to the restructuring, or based upon the results of a contemporaneous credit evaluation. Such loans will continue on nonaccrual status until the borrower has established a willingness and ability to make the restructured payments for at least six months, after which they will be classified as performing TDRs and will begin to accrue interest. Performing and nonperforming TDRs remain impaired as interest and principal will not be received in accordance with the original contractual terms of the loan agreement. Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, but may give rise to potential incremental losses. We measure impairments using a discounted cash flow method for performing TDRs and measure impairment based on collateral values for collateral-dependent nonperforming TDRs. Beginning in March 2020, as a response to COVID-19, we offered our consumer borrowers principal and interest payment deferrals, forbearance and/or extensions up to a maximum period of 18 months. We considered these programs in the context of whether or not the short-term modifications of these loans would constitute a TDR. We considered the CARES Act, interagency guidance and related guidance from the FASB, which provided that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not required to be accounted for as TDRs. As a result, we have determined that loan forbearance, modifications, deferrals and extensions made under these COVID-19 programs are not TDRs.
Allowance for Credit Losses on Loans and Reserve for Unfunded Commitments	Allowance for Credit Losses on Loans We determine the estimate of the ACL on at least a quarterly basis. The ACL represents Management's estimate of expected lifetime losses in our LHFI portfolio, excluding loans carried under the fair value option. In addition, we record a reserve for expected lifetime losses on our unfunded commitments - see Reserve for Unfunded Commitments section below. Therefore, we record ALLL on relevant financial assets and a reserve for unfunded commitments on our Consolidated Statements of Financial Condition, collectively referred to as the ACL. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual terms exclude expected extensions, renewals, and modifications unless the following applies: Management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by us. The ACL is impacted by changes in asset quality of the portfolio, including but not limited to increases in risk rating changes in our commercial portfolio, borrower delinquencies, changes in FICO scores or changes in LTVs in our consumer portfolio. In addition, while we have incorporated our forecasted impact of COVID-19 into our ACL, the ultimate impact of COVID-19 is still uncertain, including how long economic activity will be impacted by the pandemic and what effect the unprecedented levels of government fiscal and monetary actions will have on the economy and our credit losses. Specifically identified component. The specifically identified component of ACL related to performing TDR loans is generally measured as the difference between the recorded investment in the specific loan and the present value of the cash flows expected to be collected, discounted at the loan's original effective interest rate. Estimating the timing and amounts of future cash flow projections is highly judgmental and based upon assumptions including default rates, prepayment probability and loss severities. All of these estimates and assumptions require significant management judgment and certain assumptions are highly subjective. Specifically identified collateral dependent NPL loans are generally measured as the difference between the recorded investment in the impaired loan and the underlying collateral value less estimated costs to sell. These estimates are dependent on third-party property valuations which may be influenced by factors such as the current and future level of home prices, the duration of current overall economic conditions, and other macroeconomic and portfolio-specific factors. Model-based component . A general allowance is established for lifetime losses inherent on non-impaired loans by segmenting the portfolio based upon common risk characteristics. Our consumer loan portfolio is segmented into Residential First Mortgage, Home Equity and Other Consumer. Loan characteristics impacting these segments include lien position, credit quality, and loan structure. At a high-level, our commercial loans are segmented into Commercial Real Estate, Commercial and Industrial, and Warehouse Lending. Loan characteristics impacting these segments include credit quality and loan structure. We measure the allowance using the applicable dual risk rating model which measures probability of default, loss given default and exposure at default. As of December 31, 2021, we utilized the Moody’s November 2021 economic scenarios in our forecast, which were materially consistent with the December scenarios: a growth forecast, weighted at 30 percent; a baseline forecast, weighted at 40 percent; and an adverse forecast, weighted at 30 percent. Within our composite forecast, unemployment ends 2021 at 5 percent and will recover slightly in 2022, ending the year just under 5 percent. GDP continues to recover throughout 2022 and returns to pre-COVID levels in 2023. HPI decreases by just over 1 percent compared to 2021 year-end levels through the second quarter of 2022 before returning to 2021 year-end levels by the third quarter of 2022. In 2021, we judgmentally decreased our qualitative reserves by $65 million which primarily reflected our best estimates of COVID-19’s impact on our portfolios (including the estimated impact of government stimulus, forbearance/payment holidays, and Fed programs. This decline was primarily driven by a decrease in the model output from Moody’s adverse scenario, improvement in credit performance of previously identified industries and borrowers we believed could be more exposed to the stressful conditions in our forecast and decreased loans in forbearance. Qualitative adjustments . The specifically identified component analysis and the output of the model provide a reasonable starting point for our analysis, but do not, by themselves, form a sufficient basis to determine the appropriate level for the ACL. We therefore consider the qualitative factors that are likely to cause the ACL associated with our existing portfolio to differ from the output of the model. The most significant qualitative factors considered include changes in economic and business conditions, changes in nature and volume of portfolio and changes in the volume and severity of past due loans. The application of different inputs into the model calculation and the assumptions used by Management to adjust the model calculation are subject to significant management judgment and may result in actual credit losses that differ from the originally estimated amounts. Reserve for Unfunded Commitments We estimate expected credit losses over the contractual period in which we are exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by us. The ACL on unfunded commitments is adjusted as a provision for credit loss expense within the provision (benefit) for credit losses on the Consolidated Statements of
Transfers of Financial Assets	Transfers of Financial Assets    Our recognition of gain or loss on the sale of loans for which we surrender control is accounted for as a sale to the extent that 1) the transferred assets are legally isolated from us or our consolidated affiliates, even in bankruptcy or other receivership, 2) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company and 3) we do not maintain the obligation or unilateral ability to reclaim or repurchase the assets. If the sale criteria are met, the transferred financial assets are removed from the Consolidated Statements of Financial Condition and a gain or loss on sale is recognized.
Variable Interest Entities	Variable Interest Entities
Repossessed Assets	Repossessed Assets    Repossessed assets include one-to-four family residential property, commercial property and one-to-four family homes under construction that were acquired through foreclosure or acceptance of a deed-in-lieu of foreclosure. Repossessed assets are initially recorded in other assets at the estimated fair value of the collateral less estimated costs to sell. Losses arising from the initial acquisition of such properties are charged against the allowance for loan losses at the time of transfer. Subsequent valuation adjustments to reflect fair value, as well as gains and losses on disposal of these properties, are charged to general, administrative and other within noninterest expense in the Consolidated Statements of Operations as incurred. For further information, see Note 6 - Repossessed Assets and Note 20 - Fair Value Measurements.
Loans with Government Guarantees	Loans with Government Guarantees We originate government guaranteed loans which are pooled and sold as Ginnie Mae MBS. Pursuant to Ginnie Mae servicing guidelines, we have the unilateral right to repurchase loans securitized in Ginnie Mae pools that are due, but unpaid, for three consecutive months. As a result, once the delinquency criteria have been met, and regardless of whether the repurchase option has been exercised, we account for the loans as if they had been repurchased. We recognize the loans and corresponding liability as loans with government guarantees and loans with government guarantees repurchase options, respectively, in the Consolidated Statements of Financial Condition. If the loan is repurchased, the liability is cash settled and the loan with government guarantee remains. Once repurchased, we work to cure the outstanding loans such that they are re-eligible for sale or may begin foreclosure and recover losses through a claims process with the government agency, as an approved lender.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock    We own stock in the FHLB of Indianapolis, as required to permit us to obtain membership in and to borrow from the FHLB. The stock is redeemable at par and is carried at cost as no market quotes exist for the stock.
Premises and Equipment	Premises and Equipment Premises and equipment are carried at cost less accumulated depreciation. Land is carried at cost. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, which generally ranges from three
Goodwill and Intangible Assets	Goodwill and Intangible Assets The excess of the cost of an acquisition over the fair value of the net assets acquired consists primarily of goodwill, core deposit intangibles and other identifiable intangible assets. Goodwill is not amortized, but rather tested annually for impairment, or more frequently as events occur or circumstances change that would indicate the fair value is below the carrying amount. The Company may assess qualitative factors to determine whether it is more-likely-than-not the fair value is less than its carrying amount. If the Company concludes based on the qualitative assessment that goodwill may be impaired, a quantitative one-step impairment test would then be applied. An impairment loss would be recognized for any excess of carrying value over the fair value of the goodwill.
Mortgage Servicing Rights	Mortgage Servicing R ights We purchase and originate mortgage loans for sale to the secondary market and sell the loans on either a servicing-retained or servicing-released basis. If we retain the right to service the loan, an MSR is created at the time of sale which is recorded at fair value. We use an internal valuation model that utilizes an option-adjusted spread, constant prepayment speeds, costs to service and other assumptions to determine the fair value of MSRs. Management obtains third-party valuations of the MSR portfolio on a quarterly basis from independent valuation services to assess the reasonableness of the fair value calculated by our internal valuation model. Changes in the fair value of our MSRs are reported on the Consolidated Statements of Operations in net return on mortgage servicing. For further information, see Note 10 - Mortgage Servicing Rights and Note 20 - Fair Value Measurements.
Leases	Leases Effective January 1, 2019, we adopted the requirements of ASU 2016-02, Leases (Topic 842) and all related amendments. The Company elected to apply the practical expedient of forgoing the restatement of comparative periods. In addition, we elected the practical expedients permitted under transition guidance to not reassess leases entered into prior to adoption. As permitted under ASC 842, the Company made an accounting policy election to exempt leases with an initial term of twelve months or less from balance sheet recognition. Instead, short-term leases are expensed over the lease term with no impact to the balance sheet.
Servicing Fee Income	Servicing Fee Income    Servicing fee income, late fees and ancillary fees received on loans for which we own the MSR are included in net return on mortgage servicing rights on the Consolidated Statements of Operations. The fees are based on the outstanding principal and are recorded as income when earned. Subservicing fees, which are included in loan administration income on the Consolidated Statements of Operations, are based on a contractual monthly amount per loan including late fees and other ancillary income.
Revenue from Contract with Customer	Revenue from Contracts with Customers Under the guidance of the Revenue from Contracts with Customers (Topic 606), an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration received in exchange for those goods or services. Revenue is recognized when obligations, under the terms of a contract with our customer, are satisfied, which generally occurs when services are performed. Revenue is measured as the amount of consideration we expect to receive in exchange for providing services. The disaggregation of our revenue from contracts with customers is provided below: For the Years Ended December 31, Location of Revenue (1) 2021 2020 (Dollars in millions) Deposit account and other banking income Deposit fees and charges $ 22 $ 21 Debit card interchange fees Deposit fees and charges 12 11 Credit card interchange fees Other noninterest income 1 1 Wealth management Other noninterest income 8 8 Total $ 43 $ 41 (1) Recognized within the Community Banking segment. Deposit account and other banking income - We charge depositors various deposit account service fees including those for outgoing wires, overdrafts, stop payments, and ATM fees. These fees are generated from a depositor’s option to purchase services offered under the contract and are only considered a contract when the depositor exercises their option to purchase these account services. Therefore, we deem the term of our contracts with depositors to be day-to-day and do not extend beyond the services already provided. Deposit account and other banking fees are recorded at the point in time we perform the requested service. Interchange income - We collect interchange fee income when debit cards that we have issued to our customers, are used in merchant transactions. Our performance obligation is satisfied and revenue is recognized at the point we initiate the payment of funds from a customer’s account to a merchant account. Merchant fee income - We receive a percentage of merchant fees based upon card transactions processed through point-of-sale terminals at referred merchant locations. Our performance obligation is satisfied when our referral of a merchant to a payment processing vendor results in an executed agreement between the merchant and the vendor. Merchant fee revenue is recognized as received. Wealth management revenue - We earn commission income through a revenue share program based on a tiered percentage of total gross commissions generated from the sales of investment and insurance services to Flagstar customers. Commissions are earned and our performance obligation has been satisfied at the point of sale or trade execution. Our portion of earned commissions is calculated, paid and recognized as revenue on a monthly basis. We also earn revenue from portfolio management services. We receive payment in advance for portfolio management services at the beginning of each quarter for services to be performed over the quarter which results an insignificant revenue liability. We recognize this revenue over the quarter on a straight-line basis, as we believe this is the most appropriate method to measure progress towards satisfaction of the performance obligation.
Derivatives	Derivatives We utilize derivative instruments to manage the fair value changes in our MSRs, interest rate lock commitments and LHFS portfolio which are exposed to price and interest rate risk; facilitate asset/liability management; minimize the variability of future cash flows on long-term debt; and to meet the needs of our customers. All derivatives are recognized on the Consolidated Statements of Financial Condition as other assets and liabilities, as applicable, at their estimated fair value. For those derivatives designated as qualified cash flow hedges, changes in the fair value of the derivatives, to the extent effective as a hedge, are recorded in accumulated other comprehensive income, net of income taxes, and reclassified into earnings concurrently with the earnings of the hedged item. For derivative instruments designated as qualified fair value hedges, which are used to hedge the exposure of fair value changes of an asset or liability attributable to a particular risk, the gain or loss on the derivative instrument, as well as the offsetting gain or loss on the hedged item attributable to the hedged risk, are recognized in current earnings during the period. For all other derivatives, changes in the fair value of the derivative are recognized immediately in earnings. A majority of these derivatives are subject to master netting agreements and cleared through a Central Counterparty Clearing House, which mitigates non-performance risk with counterparties and enables us to settle activity on a net basis. We use interest rate swaps, swaptions, futures and forward loan sale commitments to mitigate the impact of fluctuations in interest rates and interest rate volatility on the fair value of the MSRs. Changes in their fair value are reflected in current period earnings under the net return on mortgage servicing asset. These derivatives are valued based on quoted prices for similar assets in an active market with inputs that are observable. We also enter into various derivative agreements with customers and correspondents in the form of interest rate lock commitments and forward purchase contracts which are commitments to originate or purchase mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The derivatives are valued using internal models that utilize market interest rates and other unobservable inputs. Changes in the fair value of these commitments due to fluctuations in interest rates are economically hedged through the use of forward loan sale commitments of MBS. The gains and losses arising from this derivative activity are reflected in current period earnings under the net gain on loan sales. We may utilize interest rate swaps to hedge the forecasted cash flows from our underlying variable-rate FHLB advances and forecasted FHLB advances in qualifying cash flow hedge accounting relationships. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense concurrently with the interest expense on the debt. Interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable. These hedges are evaluated for effectiveness using regression analysis at the time they are designated and then qualitatively throughout the remaining hedge period unless a change in facts and circumstances is identified. For forecasted FHLB advances being hedged, we evaluate the likelihood of the transaction occurring based on the current facts and circumstances each reporting period to ensure the hedge relationship still qualifies for hedge accounting. If we de-designate a hedge relationship or determine that an interest rate swap no longer qualifies for hedge accounting, changes in fair value are no longer recorded in other comprehensive income. The effective amounts previously recorded in other comprehensive income are recognized in earnings over the remaining life of the hedged item as an adjustment to yield, until the point it is determined that the underlying transaction is probable to not occur, at which point it is reclassified immediately into earnings. We utilize interest rate swaps to manage fair value changes of our fixed-rate FHLB advances, certain HFI residential first mortgages and certain AFS securities in qualifying fair value hedge accounting relationships. Interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable. Changes in the fair value of derivatives designated as fair value hedges, and changes in value attributable to the benchmark interest rate of the hedged item, are recognized in current period earnings and as a basis adjustment to the hedged item and hedging instrument. These hedges are evaluated for effectiveness using regression analysis at the time they are designated and then qualitatively throughout the hedge period unless a change in facts and circumstances is identified. If the Company determines an interest rate swap no longer qualifies for fair value hedge accounting or is de-designated, the hedged item will no longer be adjusted for changes in fair value and the amounts previously recorded as a basis adjustment are recognized in earnings over the remaining life of the hedged item as an adjustment to yield. If a previously hedged item is extinguished or sold, the remaining basis adjustment of the hedged item for prior fair value hedges will be reclassified to current period earnings.
Income Taxes	Income Taxes    Current income tax expense represents our estimated taxes to be paid or refunded for the current period. Deferred taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. DTAs and liabilities are measured using enacted tax rates that will apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on DTAs and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date. We evaluate our DTAs to determine if, based on all available evidence, it is more likely than not that they will be realized. If it is determined that it is more likely than not that the deferred taxes will not be realized, we establish a valuation allowance. For further information, see Note 17 - Income Taxes.
Representation and Warranty Reserve	Representation and Warranty Reserve    When we sell mortgage loans into the secondary mortgage market, we make customary representations and warranties to the purchasers about various characteristics of each loan. Upon the sale of a loan, we recognize a liability for that guarantee at its fair value as a reduction of our net gain on loan sales. Subsequent to the sale, the liability is re-measured on an ongoing basis based upon an estimate of probable future losses.
Advertising Costs	Advertising Costs    Advertising costs are expensed in the period they are incurred and are included as part of general, administrative and other noninterest expense in the Consolidated Statements of Operations.
Stock-based Compensation	Stock-Based Compensation    All share-based payments to employees, including restricted stock units, are classified as equity with expenses being recognized in compensation and benefits in the Consolidated Statements of Operations based on their fair values. The amount of compensation is measured at the grant date and is expensed over the requisite service period, which is normally the vesting period with forfeitures being recognized as they occur. In addition to share-based payments to employees, the discount provided to employees through the Employee Stock Purchase Plan is also recognized as stock-based compensation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Adoption of New Accounting Standards The following ASUs have been adopted which impact our accounting policies and/or have a financial impact: Credit Losses - Effective January 1, 2020, we have adopted the requirements of ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) and all related amendments using the modified retrospective method for all financial assets measured at amortized cost, net investments in leases and unfunded commitments. The measurement of current expected credit losses should be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. We recorded a net decrease to retained earnings of $23 million as of January 1, 2020 for the cumulative effect of adopting ASC 326. The following table illustrates the impact of adopting ASC 326: January 1, 2020 Pre-ASC 326 Adoption Impact of ASC 326 Adoption As Reported Under ASC 326 (Dollars in millions) Assets: Allowance for loan losses $ 107 $ 23 $ 130 Liabilities: Reserve for unfunded commitments $ 3 $ 7 $ 10 We adopted the following ASUs during 2021, none of which had a material impact to our financial statements: Standard Description Effective Date ASU 2021-06 Presentation of Financial Statements (Topic 205), Financial Services—Depository and Lending (Topic 942), and Financial Services—Investment Companies (Topic 946): Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants (SEC Update) July 1, 2021 ASU 2021-01 Reference Rate Reform (Topic 848): Scope January 1, 2021 ASU 2019-12 Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes January 1, 2021
Fair Value Measurements	Fair Value Measurements We utilize fair value measurements to record or disclose the fair value on certain assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability through an orderly transaction between market participants at the measurement date. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation models rely on market-based parameters when available, such as interest rate yield curves or credit spreads. Unobservable inputs may be based on Management's judgment, assumptions and estimates related to credit quality, our future earnings, interest rates and other relevant inputs. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. Valuation Hierarchy U.S. GAAP establishes a three-level valuation hierarchy for disclosure of fair value measurements. The hierarchy is based on the transparency of the inputs used in the valuation process with the highest priority given to quoted prices available in active markets and the lowest priority given to unobservable inputs where no active market exists, as discussed below: Level 1 - Quoted prices (unadjusted) for identical assets or liabilities in active markets in which we can participate as of the measurement date, Level 2 - Quoted prices for similar instruments in active markets and other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument, and Level 3 - Unobservable inputs that reflect our own assumptions about the assumptions that market participants would use in pricing an asset or liability. A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input within the valuation hierarchy that is significant to the overall fair value measurement. Transfers between levels of the fair value hierarchy are recognized at the end of the reporting period.
