Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial statements of Flagstar Bancorp, Inc. ("Flagstar," or the "Company"), including its wholly owned principal subsidiary, Flagstar Bank, FSB (the "Bank"), have been prepared using GAAP for interim financial statements. Where we say "we," "us," "our," the "Company," "Bancorp" or "Flagstar," we usually mean Flagstar Bancorp, Inc. However, in some cases, a reference to "we," "us," "our," the "Company" or "Flagstar" will include the Bank. These consolidated financial statements do not include all of the information and footnotes required by GAAP for a full year presentation and certain disclosures have been condensed or omitted in accordance with rules and regulations of the SEC. These interim financial statements are unaudited and include, in our opinion, all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of the results for the periods indicated, which are not necessarily indicative of results which may be expected for the full year. These consolidated financial statements and notes should be read in conjunction with the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2021, which is available on our website, flagstar.com, and on the SEC website at sec.gov. 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. On April 26, 2022, NYCB and Flagstar entered into Amendment No. 1 (the "Amendment") to the Merger Agreement. Under the Amendment, the parties have agreed to: extend the termination date of the Merger Agreement to October 31, 2022; Change the structure of the merger of the subsidiary banks, so that Flagstar Bank, FSB will initially convert to a national bank charter and New York Community Bank will merge with and into the national bank, with the national bank as the surviving entity; and clarify that approvals of the FDIC and the New York State Department of Financial Services are no longer required but that the approval of the OCC will be required. Other than as expressly modified by the Amendment, the Merger Agreement, remains in full force and effect. Completion of the transaction is subject to customary closing conditions, including receipt of regulatory approvals.

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 85 percent of our AFS portfolio as of March 31, 2022. 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 three months ended March 31, 2022 and the year ended December 31, 2021. We separately evaluate our HTM debt securities for any credit losses. As of March 31, 2022 and December 31, 2021, 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 $5 million at March 31, 2022 and $4 million at December 31, 2021, 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 $393 million and $86 million of AFS securities, which were comprised of U.S. government sponsored agency MBS, CD, and corporate debt obligations during the three months ended March 31, 2022 and March 31, 2021, respectively. We did not retain any passive interests in our own private MBS during the three months ended March 31, 2022 and March 31, 2021. There were no sales of AFS securities during both the three months ended March 31, 2022 and March 31, 2021 other than those related to mortgage loans that had been securitized for sale in the normal course of business. 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 both the three months ended March 31, 2022 and March 31, 2021. The following table summarizes the unrealized loss positions on AFS and HTM investment securities, by duration of the unrealized loss: Unrealized Loss Position with Unrealized Loss Position with Fair Value Number of Securities Unrealized Loss Fair Number of Unrealized (Dollars in millions) March 31, 2022 Available-for-sale securities Agency - Commercial $ 2 1 $ — $ 895 91 $ (28) Agency - Residential — — — 609 87 (34) Municipal obligations — — — 12 5 — Corporate debt obligations — — — 11 4 — Other mortgage-backed securities — 1 — 157 7 (13) Held-to-maturity securities Agency - Commercial $ — — $ — $ 86 24 $ (2) Agency - Residential — — — 90 43 (2) 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 — — — — — — Unrealized losses on AFS 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 AFS 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. The following table shows the amortized cost and estimated fair value of securities by contractual maturity: Investment Securities Available-for-Sale Investment Securities Held-to-Maturity Amortized Fair Weighted Average Amortized Fair Weighted Average (Dollars in millions) March 31, 2022 Due in one year or less $ 6 $ 6 2.16 % $ 5 $ 5 2.21 % Due after one year through five years 9 9 4.65 % 3 3 2.86 % Due after five years through 10 years 211 208 2.86 % 3 3 2.01 % Due after 10 years 1,858 1,787 2.27 % 179 175 2.49 % Total $ 2,084 $ 2,010 $ 190 $ 186 (1) Weighted-average yields are based on amortized cost weighted for the contractual maturity of each security. We pledge investment securities, primarily agency collateralized and municipal taxable mortgage obligations, to collateralize lines of credit and/or borrowings. At March 31, 2022 and December 31, 2021, we had pledged investment securities of $228 million and $1.5 billion, respectively.

Receivables [Abstract]
Loans Held-for-Sale	Loans Held-for-Sale The majority of our mortgage loans originated as LHFS are ultimately sold into the secondary market on a whole loan basis or by securitizing the loans into agency, government, or private label MBS. At March 31, 2022 and December 31, 2021, LHFS totaled $3.5 billion and $5.1 billion, respectively. For the three months ended March 31, 2022, we had net gains on loan sales associated with LHFS of $45 million as compared to $227 million for the three months ended March 31, 2021, respectively. At March 31, 2022 residential LHFS of $293 million, commercial LHFS of $18 million and corporate advances of $10 million were recorded at the lower of cost or fair value. At December 31, 2021, we recorded $116 million residential LHFS and commercial LHFS of $18 million at the lower of cost or fair value. We elected the fair value option for the remainder of the loans in the portfolio.

Receivables [Abstract]
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. We report LHFI at their amortized cost, which includes the outstanding principal balance adjusted for any unamortized premiums, discounts, deferred fees and costs. The accrued interest receivable on LHFI totaled $33 million at March 31, 2022 and $35 million at December 31, 2021 and was reported in other assets on the Consolidated Statements of Financial Condition. The following table presents our LHFI: March 31, 2022 December 31, 2021 (Dollars in millions) Consumer loans Residential first mortgage $ 1,499 $ 1,536 Home equity 596 613 Other 1,267 1,236 Total consumer loans 3,362 3,385 Commercial loans Commercial real estate 3,254 3,223 Commercial and industrial 1,979 1,826 Warehouse lending 4,641 4,974 Total commercial loans 9,874 10,023 Total loans held-for-investment $ 13,236 $ 13,408 The following table presents the UPB of our loan sales and purchases in the LHFI portfolio: Three Months Ended March 31, 2022 2021 (Dollars in millions) Loans Sold (1) Performing loans $ — $ 36 Total loans sold $ — $ 36 (1) Upon a change in our intent, the loans were transferred to LHFS and subsequently sold. 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 March 31, 2022 and December 31, 2021, we had pledged loans of $7.8 billion and $9.9 billion, respectively. 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 March 31, 2022, we utilized the Moody’s March scenarios in our forecast: 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 2022 at 4 percent, slightly increasing in 2023 with a full recovery by 2024. GDP continues to recover throughout 2022 and returns to pre-COVID levels in 2023. HPI decreases by 2 percent from the first quarter of 2022 through the fourth quarter of 2022 before increasing 3 percent by the fourth quarter of 2023. 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. The following table presents changes in the ALLL, by class of loan: Residential Home Equity Other Commercial Commercial Warehouse Total (Dollars in millions) Three Months Ended March 31, 2022 Beginning balance $ 40 $ 14 $ 36 $ 28 $ 32 $ 4 $ 154 (Benefit) provision 4 1 (1) (6) 1 (1) (2) Charge-offs (1) — (2) — (20) — (23) Recoveries — 1 1 — — — 2 Ending allowance balance $ 43 $ 16 $ 34 $ 22 $ 13 $ 3 $ 131 Three Months Ended March 31, 2021 Beginning balance $ 49 $ 25 $ 39 $ 84 $ 51 $ 4 $ 252 Benefit (2) (5) (6) — (11) — (24) Charge-offs (2) — (1) — (1) — (4) Recoveries — — 1 — 16 — 17 Ending allowance balance $ 45 $ 20 $ 33 $ 84 $ 55 $ 4 $ 241 (1) Includes LGG. The ALLL was $131 million at March 31, 2022 and $154 million at December 31, 2021. 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. Refer to payment deferral information in the Credit Risk Section of the MD&A for additional details. 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) March 31, 2022 Consumer loans Residential first mortgage $ 7 $ 8 $ 86 $ 101 $ 1,398 $ 1,499 Home equity 2 1 9 12 584 596 Other 3 1 3 7 1,260 1,267 Total consumer loans 12 10 98 120 3,242 3,362 Commercial loans Commercial real estate — — — — 3,254 3,254 Commercial and industrial — — — — 1,979 1,979 Warehouse lending — — — — 4,641 4,641 Total commercial loans — — — — 9,874 9,874 Total loans (2) $ 12 $ 10 $ 98 $ 120 $ 13,116 $ 13,236 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 (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 of past due loans accounted for under the fair value option as of March 31, 2022 and December 31, 2021. (3) Collateral dependent loans totaled $145 million and $108 million at March 31, 2022 and December 31, 2021, respectively. The majority of these loans are secured by real estate. (4) The interest income recognized on impaired loans was less than $1 million for the three months ended March 31, 2022 and December 31, 2021. (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 for the three months ended March 31, 2022 was $1 million. At March 31, 2022 and December 31, 2021, we had no loans 90 days or greater past due and still accruing interest. Reserve for Unfunded Commitments We estimated 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 reserve for unfunded commitments is adjusted as a provision for credit loss expense. 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 reflected in other liabilities on the Consolidated Statements of Financial Condition and was $14 million as of March 31, 2022, compared to $16 million as of December 31, 2021. 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. The following categories of off-balance sheet credit exposures have been identified: 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 15 - Legal Proceedings, Contingencies and Commitments. 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. 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 to the consolidated financial statements in the Annual Report on Form 10-K for the year ended December 31, 2021 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 and the programs offered to return to payment status 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 loans modified under these programs are not TDRs. The following table provides a summary of TDRs by type and performing status: TDRs Performing Nonperforming Total (Dollars in millions) March 31, 2022 Consumer loans Residential first mortgage $ 16 $ 10 $ 26 Home equity 7 2 9 Total TDRs (1)(2) $ 23 $ 12 $ 35 December 31, 2021 Consumer loans Residential first mortgage $ 14 $ 11 $ 25 Home equity 8 2 10 Total consumer TDR 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 (1) The ALLL on TDR loans totaled $4 million at both March 31, 2022 and December 31, 2021. (2) Includes $3 million and $5 million of TDR loans accounted for under the fair value option at March 31, 2022 and December 31, 2021, respectively. The following table provides a summary of newly modified TDRs: New TDRs Number of Accounts Pre-Modification Unpaid Principal Balance Post-Modification Unpaid Principal Balance (1) (Dollars in millions) Three Months Ended March 31, 2022 Residential first mortgages 9 $ 2 $ 2 Home equity (2)(3) 1 — — Commercial Real Estate — — — Total TDR loans 10 $ 2 $ 2 Three Months Ended March 31, 2021 Residential first mortgages 6 $ 3 $ 3 Total TDR loans 6 $ 3 $ 3 (1) Post-modification balances include past due amounts that are capitalized at modification date. (2) Home equity post-modification UPB reflects write downs. (3) Includes loans carried at the fair value option. There were no loans modified in the previous 12 months that subsequently defaulted during the three months ended March 31, 2022. 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 HELOANs 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 LTVs 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: Revolving Loans Converted to Term Loans Amortized Cost Basis December 31, 2021 Term Loans Revolving Loans Amortized Cost Basis Total Amortized Cost Basis by Closing Year As of March 31, 2022 2022 2021 2020 2019 2018 Prior Commercial Loans (Dollars in million) Commercial real estate Pass $ 63 $ 546 $ 256 $ 437 $ 290 $ 633 $ 869 $ — $ 3,094 $ 3,071 Watch — — 7 1 13 83 32 — 136 128 Special mention — — — 2 — 22 — — 24 2 Substandard — — — — — — — — — 22 Commercial and industrial Pass 7 265 75 163 26 93 1,254 — 1,883 1,685 Watch — 4 12 — 9 — 14 — 39 71 Special mention — 9 — — — — — — 9 — Substandard — — — — 18 2 28 — 48 70 Warehouse Pass 4,496 — — — — — — — 4,496 4,834 Watch 145 — — — — — — — 145 140 Special mention — — — — — — — — — — Substandard — — — — — — — — — — Total commercial loans $ 4,711 $ 824 $ 350 $ 603 $ 356 $ 833 $ 2,197 $ — $ 9,874 $ 10,023 Revolving Loans Converted to Term Loans Amortized Cost Basis December 31, 2020 Term Loans Revolving Loans Amortized Cost Basis Total 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 with Government Guarantees	3 Months Ended
	Mar. 31, 2022
Receivables [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 in Other liabilities on the Consolidated Statements of Financial Condition. As of March 31, 2022 this liability was $63 million, as compared to a balance of $200 million as of December 31, 2021. 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 March 31, 2022 and December 31, 2021, LGG totaled $1.3 billion and $1.7 billion, respectively. Repossessed assets and the associated claims related to government guaranteed loans are recorded in other assets and totaled $11 million and $7 million, at March 31, 2022 and December 31, 2021, respectively.

Variable Interest Entities

Disclosure of Transfer of Securitizations or Asset-backed Financing Financial Assets Accounted for as Sale [Abstract]
Variable Interest Entities	Variable Interest Entities    We have no consolidated VIEs as of March 31, 2022 and December 31, 2021.    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 servicer 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 $245 million as of March 31, 2022 as well as the standard representations and warranties made in conjunction with the loan transfers. See Note 2 - Investment Securities and Note 16 - Fair Value Measurements, for additional information.

Mortgage Servicing Rights

Mortgage Servicing Rights	3 Months Ended
	Mar. 31, 2022
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 8 - Derivative Financial Instruments. Changes in the fair value of residential first mortgage MSRs were as follows: Three Months Ended March 31, 2022 2021 (Dollars in millions) Balance at beginning of period $ 392 $ 329 Additions from loans sold with servicing retained 79 65 Purchases 13 — Reductions from sales — — Decrease in MSR fair value due to pay-offs, pay-downs, run-off, model changes, and other (1) (8) (39) Changes in estimates of fair value due to interest rate risk (1) (2) 47 73 Fair value of MSRs at end of period $ 523 $ 428 (1) Changes in fair value are included within net return on mortgage servicing rights on the Consolidated Statements of Operations.

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: March 31, 2022 December 31, 2021 Fair value Fair value Actual 10% adverse change 20% adverse change Actual 10% adverse change 20% adverse change (Dollars in millions) Option adjusted spread 6.59 % $ 513 $ 503 7.12 % $ 383 $ 374 Constant prepayment rate 8.69 % 506 490 9.24 % 373 355 Weighted average cost to service per loan $ 79.25 518 512 $ 79.38 387 383 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 16 - 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. The following table summarizes income and fees associated with owned MSRs: Three Months Ended March 31, 2022 2021 (Dollars in millions) Net return (loss) on mortgage servicing rights Servicing fees, ancillary income and late fees (1) $ 30 $ 31 Decreases in MSR fair value due to pay-offs, pay-downs, run-off, model changes, and other (8) (39) Changes in fair value due to interest rate risk 47 73 Loss on MSR derivatives (2) (41) (65) Net transaction costs 1 — Total return included in net return on mortgage servicing rights $ 29 $ — (1) Servicing fees are recorded on an accrual basis.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments Derivative financial instruments are recorded at fair value in other assets and other liabilities on the Consolidated Statements of Financial Condition. Our policy is to present our derivative assets and derivative liabilities on the Consolidated Statements of Financial Condition on a gross basis, even when provisions allowing for set-off are in place. 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 U.S. 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 AFS using the last-of-layer method. Cash flows and the income 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 commercial loans. Changes in the fair value of derivatives designated as cash flow hedges are recorded in OCI on the Consolidated Statements of Financial Condition and reclassified into interest income in the same period in which the hedge transaction is recognized in earnings. During the first quarter of 2022, we de-designated all of our cash flow hedges of custodial deposits. We evaluate the probability of hedged forecasted transactions on at least a quarterly basis relating to amounts deferred in OCI. Amounts recorded in OCI related to de-designated cash flow hedges of forecasted transactions, which remain probable to occur, are reclassified into net loan administration income in the same period in which the hedged transaction is recognized into earnings. We had 46 million (net-of-tax) of unrealized gains on de-designated cash flow hedges recorded in AOCI as of March 31, 2022. The estimated amount to be reclassified from OCI into earnings on de-designated hedging relationships during the next 12 months represents $10 million (net-of-tax) of gains. We had $5 million (net-of-tax) of unrealized losses on derivatives designated in a hedge relationship as of March 31, 2022. The estimated amount to be reclassified from OCI into earnings during the next 12 months beginning March 31, 2022 represents $9 million of gains (net-of-tax). At December 31, 2021, we had $20 million (net-of-tax) of unrealized gains on derivatives classified as cash flow hedges recorded in AOCI. 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 March 31, 2022. The following tables present the notional amount, estimated fair value and maturity of our derivative financial instruments: March 31, 2022 (1) Notional Amount Fair Value (2) Expiration Dates (Dollars in millions) Derivatives in cash flow hedge relationships: Assets Interest rate swaps on commercial loans $ 2,000 $ 2 2025 Derivatives in fair value hedge relationships: Assets Interest rate swaps on AFS securities $ 100 $ — 2022 Interest rate swaps on subordinated debt 150 — 2025 Total $ 250 $ — Derivatives not designated as hedging instruments: Assets Futures $ 1,053 $ 2 2022-2023 Mortgage-backed securities forwards 11,684 200 2022 Rate lock commitments 3,259 23 2022 Interest rate swaps and swaptions 5,064 105 2022-2052 Total $ 21,060 $ 330 Liabilities Mortgage-backed securities forwards $ 4,629 $ 45 2022 Rate lock commitments 2,112 27 2022 Interest rate swaps 1,771 22 2022-2032 Total $ 8,512 $ 94 (1) Variation margin pledged to, or received from, a Central Counterparty Clearing House to cover the prior day's fair value of open positions is considered a settlement of the derivative position for accounting purposes.

Losses of $1 million on fair value hedging relationships of AFS securities were recorded in interest income for the three months ended both March 31, 2022 and March 31, 2021. Losses of $1 million on cash flow hedging relationships of custodial deposits were reclassified from AOCI into loan administration income during the three months ended March 31, 2022 and March 31, 2021. Gains and losses on fair value hedging relationships of HFI residential first mortgages for the three months ended March 31, 2022 and March 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 $83 million at March 31, 2022 and $1.0 billion at December 31, 2021 of which a de-minimis amount and unrealized losses of $5 million, respectively, were due to the fair value hedge relationships. The closed portfolio of AFS securities designated in this last-of-layer method hedge was $86 million par (amortized cost of $85 million) at March 31, 2022 and $1.0 billion par (amortized cost of $1.0 billion) at December 31, 2021, of which $86 million and $435 million were designated in active hedge relationships at March 31, 2022 and December 31, 2021, respectively. The fair value basis adjustment associated with de-designated last-of-layer hedges of AFS securities is $17 million at March 31, 2022. The basis adjustment is allocated to individual securities recorded in available-for-sale securities within the Consolidated Statements of Financial Condition and will be accreted into interest income over the remaining life of those securities. At March 31, 2022, we pledged a total of $99 million related to derivative financial instruments, consisting of $28 million of cash collateral on derivative liabilities and $71 million of maintenance margin on centrally cleared derivatives. We had an obligation to return a total of $173 million of cash collateral on derivative assets at March 31, 2022. 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 at December 31, 2021. Within the Consolidated Statements of Financial Condition, the collateral related to derivative activity is included in other assets and other liabilities and the cash pledged as maintenance margin is restricted and included in other assets.

Banking and Thrift, Other Disclosures [Abstract]
Regulatory Matters	Regulatory Matters 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 March 31, 2022 and December 31, 2021.

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 March 31, 2022, 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. Other litigation accruals At March 31, 2022 and December 31, 2021, our total accrual for contingent liabilities and settled litigation was $9 million. 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: March 31, 2022 December 31, 2021 (Dollars in millions) Commitments to extend credit Mortgage loan commitments including interest rate locks $ 5,371 $ 5,539 Warehouse loan commitments 7,675 6,840 Commercial and industrial commitments 1,764 1,582 Other construction commitments 2,877 2,719 HELOC commitments 727 631 Other consumer commitments 349 273 Standby and commercial letters of credit 102 107 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 8 - 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.

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.

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) March 31, 2022 Assets Loans held-for-investment Mortgage servicing rights $ 523 Discounted cash flows Option adjusted spread 3.8% - 21.6% (6.6%) 0% - 10.3% (8.7%) $67 - $90 ($80) (1) Rate lock commitments (net) $ (4) Consensus pricing Origination pull-through rate 77.2% (1) (1) Unobservable inputs were weighted by their relative fair value of the instruments. 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) (1) Unobservable inputs were weighted by their relative fair value of the instruments. Recurring Significant Unobservable Inputs Home equity. The most significant unobservable inputs used in the fair value measurement of the HELOANs 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 March 31, 2022 and December 31, 2021, the weighted average life (in years) for the entire MSR portfolio was 6.7 and 5.8, 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 March 31, 2022. 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 15 - 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 Losses (Dollars in millions) March 31, 2022 Loans held-for-sale (2) $ 293 $ 293 $ — $ (1) Commercial loans 18 — 18 — Impaired loans held-for-investment (2) Residential first mortgage loans 72 — 72 (8) Repossessed assets (3) 4 — 4 (1) Totals $ 387 $ 293 $ 94 $ (10) December 31, 2021 Loans held-for-sale (2) $ 116 $ 116 $ — $ (1) Commercial loans 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) (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) March 31, 2022 Commercial loans $ 18 Fair value of collateral Market price N/A Impaired loans held-for-investment Residential first mortgage loans (1) $ 72 Fair value of collateral Loss severity discount 0% - 100% (9.8%) Repossessed assets (1) $ 4 Fair value of collateral Loss severity discount 0% - 98.0% (25.4%) December 31, 2021 Impaired loans-held-for sale Commercial loans HFS $ 18 Fair value of collateral Market price N/A Impaired loans held-for-investment Residential first mortgage loans (1) $ 36 Fair value of collateral Loss severity discount 0% - 100% (12.7%) Repossessed assets (1) $ 6 Fair value of collateral Loss severity discount 0% - 96.3% (19.8%) (1) Unobservable inputs were weighted by their relative fair value of the instruments. 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: March 31, 2022 Estimated Fair Value Carrying Value Total Level 1 Level 2 Level 3 (Dollars in millions) Assets Cash and cash equivalents $ 405 $ 405 $ 405 $ — $ — Investment securities available-for-sale 2,010 2,010 — 2,010 — Investment securities held-to-maturity 190 186 — 186 — Loans held-for-sale 3,475 3,475 — 3,475 — Loans held-for-investment 13,236 13,197 — 21 13,176 Loans with government guarantees 1,256 1,256 — 1,256 — Mortgage servicing rights 523 523 — — 523 Federal Home Loan Bank stock 329 329 — 329 — Bank owned life insurance 367 367 — 367 — Repossessed assets 4 4 — — 4 Other assets, foreclosure claims 11 11 — 11 — Derivative financial instruments, assets 330 330 — 307 23 Liabilities Retail deposits Demand deposits and savings accounts $ (9,277) $ (7,972) $ — $ (7,972) $ — Certificates of deposit (898) (901) — (901) — Wholesale deposits (974) (952) — (952) — Government deposits (1,886) (1,748) — (1,748) — Company controlled deposits (4,313) (4,264) — (4,264) — Federal Home Loan Bank advances (1,400) (1,395) — (1,395) — Long-term debt (396) (346) — (346) — Derivative financial instruments, liabilities (94) (94) — (67) (27) 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) 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. Interest income on LHFS is accrued on the principal outstanding primarily using the "simple-interest" method. The following table reflects the change in fair value included in earnings of financial instruments for which the fair value option has been elected: Three Months Ended March 31, 2022 2021 (Dollars in millions) Assets Loans held-for-sale Net gain on loan sales $ (294) $ 87 Liabilities DOJ Liability Other noninterest expense $ — $ 35 The following table reflects the difference between the aggregate fair value and aggregate remaining contractual principal balance outstanding for assets and liabilities for which the fair value option has been elected: March 31, 2022 December 31, 2021 UPB Fair Value Fair Value Over / (Under) UPB UPB Fair Value Fair Value Over / (Under) UPB (Dollars in millions) Assets Nonaccrual loans Loans held-for-sale $ 25 $ 23 $ (2) $ 18 $ 16 $ (2) Loans held-for-investment 14 11 (3) 15 13 (2) Total nonaccrual loans $ 39 $ 34 $ (5) $ 33 $ 29 $ (4) Other performing loans Loans held-for-sale $ 3,188 $ 3,131 $ (57) $ 4,790 $ 4,904 $ 114 Loans held-for-investment 12 10 (2) 5 3 (2) Total other performing loans $ 3,200 $ 3,141 $ (59) $ 4,795 $ 4,907 $ 112 Total loans Loans held-for-sale $ 3,213 $ 3,154 $ (59) $ 4,808 $ 4,920 $ 112 Loans held-for-investment 26 21 (5) 20 16 (4) Total loans $ 3,239 $ 3,175 $ (64) $ 4,828 $ 4,936 $ 108

Segment Information

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. The following tables present financial information by business segment for the periods indicated: Three Months Ended March 31, 2022 Community Banking Mortgage Originations Mortgage Servicing Other (1) Total (Dollars in millions) Summary of Operations Net interest income $ 122 $ 56 $ 3 $ (16) $ 165 Provision (benefit) for credit losses 22 3 — (29) (4) Net interest income after benefit for credit losses 100 53 3 13 169 Net gain on loan sales — 45 — — 45 Loan fees and charges — 6 21 — 27 Net return on mortgage servicing rights — 29 — — 29 Loan administrative (expense) income — (7) 43 (3) 33 Other noninterest income 18 1 — 7 26 Total noninterest income 18 74 64 4 160 Compensation and benefits 28 45 16 38 127 Commissions 1 25 — — 26 Loan processing expense 2 9 9 1 21 General, administrative and other 18 11 21 37 87 Total noninterest expense 49 90 46 76 261 Income (loss) before indirect overhead allocations and income taxes 69 37 21 (59) 68 Indirect overhead allocation (expense) income (10) (15) (6) 31 — Provision (benefit) for income taxes 12 4 3 (4) 15 Net income (loss) $ 47 $ 18 $ 12 $ (24) $ 53 Intersegment revenue (expense) $ 22 $ 9 $ 9 $ (40) $ — Average balances Loans held-for-sale $ 18 $ 4,815 $ — $ — $ 4,833 Loans with government guarantees — 1,404 (2) — 1,402 Loans held-for-investment (2) 10,942 1,442 — — 12,384 Total assets 11,326 8,695 167 3,973 24,161 Deposits 12,006 42 5,016 1,025 18,089 (1) Includes offsetting adjustments made to reclassify income and expenses relating to operating leases and custodial deposits for subservicing clients.

Credit Quality	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 HELOANs 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.
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.
