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 U.S. 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 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, 2019

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Investment Securities Securitized HFS loans not sold Trading securities arise as mortgage loans are securitized for sale in the normal of business. Trading securities are carried at fair value. Changes in fair value on trading securities are recorded in current period earnings. At March 31, 2020 , we held $2,058 million of these securities at fair value, which were comprised of U.S. government sponsored agency MBS. We had no trading securities at December 31, 2019 . The following table presents our AFS and HTM investment securities: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (Dollars in millions) March 31, 2020 Available-for-sale securities Agency - Commercial $ 1,269 $ 17 $ (1 ) $ 1,285 Agency - Residential 971 33 — 1,004 Municipal obligations 30 — — 30 Corporate debt obligations 67 1 (1 ) 67 Other MBS 58 1 — 59 Certificate of deposits 1 — — 1 Total available-for-sale securities (1) $ 2,396 $ 52 $ (2 ) $ 2,446 Held-to-maturity securities Agency - Commercial $ 279 $ 3 $ — $ 282 Agency - Residential 275 12 — 287 Total held-to-maturity securities (1) $ 554 $ 15 $ — $ 569 December 31, 2019 Available-for-sale securities Agency - Commercial $ 948 $ 2 $ (3 ) $ 947 Agency - Residential 1,015 4 (4 ) $ 1,015 Corporate debt obligations 76 1 — $ 77 Municipal obligations 31 — — $ 31 Other MBS 44 1 — $ 45 Certificate of Deposits 1 — — $ 1 Total available-for-sale securities (1) $ 2,115 $ 8 $ (7 ) $ 2,116 Held-to-maturity securities Agency - Commercial $ 306 $ — $ (1 ) $ 305 Agency - Residential 292 3 (1 ) 294 Total held-to-maturity securities (1) $ 598 $ 3 $ (2 ) $ 599 (1) There were no securities of a single issuer, which are not governmental or government-sponsored, that exceeded 10 percent of stockholders’ equity at March 31, 2020 or December 31, 2019 . 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 credit loss assumption and represented 95 percent of our AFS portfolio as of March 31, 2020 . For the remaining AFS securities, credit losses are recognized as an increase to the allowance for credit losses through the credit loss provision. If any of the decline in fair value is related to market factors, that amount is recognized in accumulated other comprehensive income (OCI). We have no unrealized credit losses as of March 31, 2020 and December 31, 2019 . We separately evaluate our HTM debt securities for any credit losses. As of March 31, 2020 and December 31, 2019 , our entire HTM portfolio qualified for the zero loss assumption as all securities are guaranteed by the U.S. Treasury, U.S. government agencies or sovereign entities of high credit quality. 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 $7 million and $6 million at March 31, 2020 and December 31, 2019 , and was reported in Other Assets on the Consolidated Statements of Financial Condition. Available-for-sale securities Securities available-for-sale are carried at fair value. Unrealized gains and losses on AFS securities are reported as a component of other comprehensive income. We purchased $350 million and $16 million of AFS securities, which were comprised of U.S. government sponsored agency MBS, certificate of deposits, and corporate debt obligations during the three months ended March 31, 2020 , and March 31, 2019 respectively. In addition, we retained $18 million of passive interests in our own private MBS during the three months ended March 31, 2020 . We did no t retain any interest in our own private MBS during the three months ended March 31, 2019 . There were no in sales of AFS securities during both the three months ended March 31, 2020 , and March 31, 2019 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, 2020 and March 31, 2019 . The following table summarizes available-for-sale and held-to-maturity securities, by duration, the unrealized loss positions on investment securities: Unrealized Loss Position with Duration 12 Months and Over Unrealized Loss Position with Duration Under 12 Months Fair Value Number of Securities Unrealized Loss Fair Value Number of Securities Unrealized Loss (Dollars in millions) March 31, 2020 Available-for-sale securities Agency - Commercial $ 35 4 $ — $ 91 9 $ (1 ) Municipal obligations $ — 1 $ — $ — — $ — Corporate debt obligations $ — — $ — $ 21 5 $ (1 ) Held-to-maturity securities Agency - Commercial $ 3 1 $ — $ 5 1 $ — December 31, 2019 Available-for-sale securities Agency - Commercial $ 148 17 $ (3 ) $ 303 19 $ — Agency - Residential $ 266 26 $ (3 ) $ 148 14 $ (1 ) Municipal obligations $ 8 3 $ — $ — — $ — Held-to-maturity securities Agency - Commercial $ 148 13 $ (1 ) $ 85 6 $ — Agency - Residential $ 35 7 $ (1 ) $ 38 10 $ — 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. 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 Cost Fair Value Weighted Average Yield Amortized Cost Fair Value Weighted Average Yield (Dollars in millions) March 31, 2020 Due in one year or less $ 3 $ 3 2.04 % $ — $ — — % Due after one year through five years 11 11 2.68 % 9 9 2.49 % Due after five years through 10 years 102 104 4.03 % 8 9 2.28 % Due after 10 years 2,280 2,328 2.42 % 537 551 2.44 % Total $ 2,396 $ 2,446 $ 554 $ 569 We pledge investment securities, primarily agency collateralized and municipal taxable mortgage obligations, to collateralize lines of credit and/or borrowings. At March 31, 2020 and December 31, 2019 , we had pledged investment securities of $828 million and $874 million , respectively.

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 mortgage-backed securities. LHFS totaled $4.4 billion and $5.3 billion at March 31, 2020 and December 31, 2019 , respectively. For the three months ended March 31, 2020 we had net gain on loan sales associated with LHFS of $89 million , as compared to $47 million for the three months ended March 31, 2019 . At March 31, 2020 and December 31, 2019 , $24 million and $39 million , respectively, of LHFS were recorded at lower of cost or fair value. We elected the fair value option for the remainder of the loans in the portfolio.

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 an at least 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 rating for the borrowing relationship. Based on the most recent 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 Amortized Cost Basis by Origination Year As of March 31, 2020 2020 2019 2018 2017 2016 Prior Commercial Loans Commercial real estate Pass $ 166 $ 999 $ 519 $ 546 $ 355 $ 278 $ (1 ) $ — $ 2,862 Watch 20 13 71 42 38 34 — — 218 Special mention — — 7 — — — — — 7 Substandard — — — 5 — — — — 5 Commercial and industrial Pass 236 614 277 332 184 114 24 — 1,781 Watch 1 6 6 42 — 1 1 — 57 Special mention — 11 18 9 — — — — 38 Substandard — — — 4 — — — — 4 Warehouse Pass — — — — — — 3,720 — 3,720 Watch — — — — — — 222 — 222 Special mention — — — — — — 31 — 31 Substandard — — — — — — — — — Total commercial loans $ 423 $ 1,643 $ 898 $ 980 $ 577 $ 427 $ 3,997 $ — $ 8,945" id="sjs-B4">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.

At March 31, 2020 we had pledged loans of $8.3 billion , compared to $9.1 billion at December 31, 2019 . Allowance for Loan Losses We determine the estimate of the allowance for loan losses on at least a quarterly basis. The allowance for loan losses represents management's estimate of lifetime losses in our LHFI portfolio, excluding loans carried under the fair value option. We establish an allowance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The allowance uses a loan-level, model-based approach, to estimate the expected lifetime credit losses. For non-performing loans, we've elected to use the collateral dependent practical expedient. The reserve for collateral dependent loans is established as the difference between fair value of the collateral less cost to sell and the amortized cost of the loan. Management applies judgment and assigns qualitative factors to each loan portfolio segment or the portfolio as a whole based upon the consideration of the following factors: levels of and trends in delinquencies and performance of loans, levels of and trends in write-offs and recoveries collected, changes in the nature and volume of the portfolio, changes in reasonable and supportable economic forecasts, changes in lending policies and procedures, changes in economic and business conditions, changes in lending management, changes in credit quality statistics, changes in the quality of the loan review system, changes in prepayment expectations or other factors affecting assessments of loan contractual term, changes in concentrations of credit, industry conditions and other internal or external factor changes. A specific allowance is established on impaired loans when it is probable all amounts due will not be collected pursuant to the original contractual terms of the loan and the recorded investment in the loan exceeds its fair value. The required allowance is measured using either the present value of the expected future cash flows discounted at the loan's effective interest rate or the fair value of the collateral less estimated costs to sell if the loan is collateral dependent. 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, 2020 , we estimated losses over a two-year reasonable and supportable forecast period using a macroeconomic scenario before reverting economic variables over a one-year period to its long-term historical averages on a straight-line basis. As of March 31, 2020 , we forecasted that we are in a sudden, sharp and severe downturn as a result of the COVID-19 pandemic, only partially recovering later in the year. Our forecast includes an annualized GDP contraction of 18 percent during the second quarter, a 3 percent decrease in HPI throughout the remainder of the year, and a 9 percent spike in unemployment during the second quarter before moderating to 7 percent at the end of the year. The following table presents changes in the allowance for loan losses, by class of loan: Residential First Mortgage (1) Home Equity Other Consumer Commercial Real Estate Commercial and Industrial Warehouse Lending Total (Dollars in millions) Three Months Ended March 31, 2020 Beginning balance, prior to adoption of ASC 326 $ 22 $ 14 $ 6 $ 38 $ 22 $ 5 $ 107 Impact of adopting ASC 326 25 12 10 (14 ) (6 ) (4 ) 23 Provision (benefit) — (2 ) — 4 2 — 4 Charge-offs (1 ) (1 ) (1 ) — — — (3 ) Recoveries — — 1 — — — 1 Ending allowance balance $ 46 $ 23 $ 16 $ 28 $ 18 $ 1 $ 132 Three Months Ended March 31, 2019 Beginning balance $ 38 $ 15 $ 3 $ 48 $ 18 $ 6 $ 128 Provision (benefit) (2 ) — 2 (12 ) 12 — — Charge-offs (1 ) — (1 ) — — — (2 ) Recoveries — 1 — — — — 1 Ending allowance balance $ 35 $ 16 $ 4 $ 36 $ 30 $ 6 $ 127 (1) Includes loans with government guarantees. The allowance for loan losses was $132 million at March 31, 2020 and $127 million at March 31, 2019 . The increase in the allowance is reflective of the adoption of CECL and an increase due to changes in the economic forecast used in the ACL models as a result of the ongoing COVID-19 pandemic, partially offset by sustained low delinquencies and charge-off levels. 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. 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 when we believe they will be able to fulfill all of their contractual commitments. 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 nonperforming loans). 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 measure an allowance for credit losses for accrued interest receivables as accrued interest is written off in a timely manner. 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 presents the amortized cost basis of loans for which the reserve is established based on collateral value, by class of loan: Balance at March 31, 2020 Real Estate Consumer loans Residential first mortgage $ 44 Home equity 20 Other 2 Total $ 66 As of March 31, 2020 , all loans for which the reserve is established based on collateral value are secured by collateral worth equal to or in excess of amortized cost. There were no impaired commercial loans as of March 31, 2020 . The following table sets forth the LHFI aging analysis of past due and current loans: 30-59 Days Past Due 60-89 Days Past Due 90 Days or Greater Past Due (1) Total Past Due Current Total LHFI (Dollars in millions) March 31, 2020 Consumer loans Residential first mortgage $ 8 $ 3 $ 24 $ 35 $ 2,929 $ 2,964 Home equity 2 1 3 6 1,022 1,028 Other 4 1 2 7 851 858 Total consumer loans 14 5 29 48 4,802 4,850 Commercial loans Commercial real estate 6 — — 6 3,086 3,092 Commercial and industrial (1) 1 — — 1 1,879 1,880 Warehouse lending — — — — 3,973 3,973 Total commercial loans 7 — — 7 8,938 8,945 Total loans (2) $ 21 $ 5 $ 29 $ 55 $ 13,740 $ 13,795 December 31, 2019 Consumer loans Residential first mortgage $ 5 $ 4 $ 21 $ 30 $ 3,124 $ 3,154 Home Equity 1 — 4 5 1,019 1,024 Other 3 1 1 5 724 729 Total consumer loans 9 5 26 40 4,867 4,907 Commercial loans Commercial real estate — — — — 2,828 2,828 Commercial and industrial — — — — 1,634 1,634 Warehouse lending — — — — 2,760 2,760 Total commercial loans — — — — 7,222 7,222 Total loans (2) $ 9 $ 5 $ 26 $ 40 $ 12,089 $ 12,129 (1) Includes less than 90 day past due performing loans which are deemed nonaccrual. Interest is not being accrued on these loans. (2) Includes $4 million of past due loans accounted for under the fair value option for both March 31, 2020 and December 31, 2019 , respectively. Interest income is recognized on nonaccrual loans using a cash basis method. Interest that would have been accrued on impaired loans was less than $1 million during both the three months and twelve months ended March 31, 2020 and December 31, 2019 , respectively. At March 31, 2020 and December 31, 2019 , we had no loans 90 days 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 Statement of Financial Condition and was $20 million as of March 31, 2020 , compared to $3 million as of March 31, 2019 . The increase in the reserve is reflective of the adoption of CECL which requires us to record an allowance for our estimate of lifetime losses and an increase due to changes in the economic forecast used in the ACL models as a result of the ongoing COVID-19 pandemic. 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. 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 to the consolidated financial statements in the Annual Report on Form 10-K for the year ended December 31, 2019 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 have offered our consumer and commercial customer’s principal and interest payment deferrals and extensions. We considered these programs in the context of whether or not the restructuring of these contracts would constitute a Troubled Debt Restructuring (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. The following table provides a summary of TDRs by type and performing status: TDRs Performing Nonperforming Total (Dollars in millions) March 31, 2020 Consumer loans Residential first mortgage $ 20 $ 8 $ 28 Home equity 17 2 19 Total TDRs (1)(2) $ 37 $ 10 $ 47 December 31, 2019 Consumer loans Residential first mortgage $ 20 $ 8 $ 28 Home Equity 18 2 20 Total TDRs (1)(2) $ 38 $ 10 $ 48 (1) Allowance for loan losses on TDR loans totaled $5 million and $8 million at March 31, 2020 and December 31, 2019, respectively. (2) Includes $2 million of TDR loans accounted for under the fair value option at March 31, 2020 and December 31, 2019 .

There was one residential first mortgage loans modified in the previous 12 months that subsequently defaulted during the three months ended March 31, 2020 . There were no residential first mortgage loans modified in the previous 12 months that subsequently defaulted during the three months ended March 31, 2019 . The increase in allowance at modification was less than $1 million for the three months ended March 31, 2020 and March 31, 2019 . All TDR classes within the consumer and commercial portfolios are considered subsequently defaulted when they are greater than 90 days past due within 12 months of the restructuring date. Impaired Loans The interest income recognized on impaired loans was less than $1 million for the three months ended March 31, 2020 and March 31, 2019 . Credit Quality We utilize an internal risk rating system which is applied to all consumer and commercial loans. Descriptions of our internal 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. They 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 non-accrual 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 non-accrual. 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, but, 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, and includes consumer 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 Substandard. Payment activity, credit rating and loan-to-value ratios have the most significant impact on the ACL for consumer 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 an at least 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 rating for the borrowing relationship. Based on the most recent 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 Amortized Cost Basis by Origination Year As of March 31, 2020 2020 2019 2018 2017 2016 Prior Commercial Loans Commercial real estate Pass $ 166 $ 999 $ 519 $ 546 $ 355 $ 278 $ (1 ) $ — $ 2,862 Watch 20 13 71 42 38 34 — — 218 Special mention — — 7 — — — — — 7 Substandard — — — 5 — — — — 5 Commercial and industrial Pass 236 614 277 332 184 114 24 — 1,781 Watch 1 6 6 42 — 1 1 — 57 Special mention — 11 18 9 — — — — 38 Substandard — — — 4 — — — — 4 Warehouse Pass — — — — — — 3,720 — 3,720 Watch — — — — — — 222 — 222 Special mention — — — — — — 31 — 31 Substandard — — — — — — — — — Total commercial loans $ 423 $ 1,643 $ 898 $ 980 $ 577 $ 427 $ 3,997 $ — $ 8,945

Receivables [Abstract]
Loans with Government Guarantees	Loans with Government Guarantees Substantially all loans with government guarantees are insured or guaranteed by the FHA or the U.S. Department of Veterans Affairs. FHA loans earn interest at a rate based upon the 10 -year U.S. Treasury note rate at the time the underlying loan becomes delinquent, which is not paid by the FHA or the U.S. Department of Veterans Affairs until claimed. 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 allowance for loan losses on residential first mortgages. Repossessed assets and the associated claims related to government guaranteed loans are recorded in other assets and totaled $40 million and $45 million , at March 31, 2020 and December 31, 2019 , respectively.

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, 2020 and December 31, 2019 . In connection with our 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 investment in the VIE, as well as the standard representations and warranties made in conjunction with the loan transfer. See Note 2 - Investment Securities and Note 16

Mortgage Servicing Rights

Mortgage Servicing Rights	3 Months Ended
	Mar. 31, 2020
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 increases in 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, 2020 2019 (Dollars in millions) Balance at beginning of period $ 291 $ 290 Additions from loans sold with servicing retained 40 67 Reductions from sales (36 ) (45 ) Decrease in MSR fair value due to pay-offs, pay-downs, run-off, model changes, and other (1) (22 ) (11 ) Changes in estimates of fair value due to interest rate risk (1) (2) (50 ) (23 ) Fair value of MSRs at end of period $ 223 $ 278 (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: March 31, 2020 December 31, 2019 Fair value Fair value Actual 10% adverse change 20% adverse change Actual 10% adverse change 20% adverse change (Dollars in millions) Option adjusted spread 5.56 % $ 220 $ 217 5.34 % $ 284 $ 280 Constant prepayment rate 12.04 % 206 191 10.59 % 271 257 Weighted average cost to service per loan $ 84.59 221 218 $ 84.41 285 282 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 mortgage servicing rights: Three Months Ended March 31, 2020 2019 (Dollars in millions) Net return (loss) on mortgage servicing rights Servicing fees, ancillary income and late fees (1) $ 21 $ 19 Decrease in MSR fair value due to pay-offs, pay-downs, run-off, model changes, and other (22 ) (11 ) Changes in fair value due to interest rate risk (50 ) (23 ) Gain on MSR derivatives (2) 58 22 Net transaction costs (1 ) (1 ) Total return (loss) included in net return on mortgage servicing rights $ 6 $ 6 (1) Servicing fees are recorded on an accrual basis.

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 its derivative assets and derivative liabilities on the Consolidated Statement 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, 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. Changes in fair value of derivatives not designated as hedging instruments are recognized in 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 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 (loss) 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 March 31, 2020 , we had $4 million (net-of-tax) of unrealized losses on derivatives classified as cash flow hedges recorded in accumulated other comprehensive income (loss). We had no designated cash flow hedges at December 31, 2019 . The estimated amount to be reclassified from other comprehensive income into earnings during the next 12 months represents $2 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 March 31, 2020 .

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 $1,403 million at March 31, 2020 and $287 million at December 31, 2019 of which $6 million and $1 million respectively, was due to the fair value hedge relationship. The closed portfolio of AFS securities designated in this last layer method hedge was $1.38 billion par (amortized cost of $1.38 billion ) at March 31, 2020 and $291 million par (amortized cost of $289 million ) at December 31, 2019 of which we have designated $450 million and $100 million at March 31, 2020 and December 31, 2019 , respectively. The net gain recognized on designated instruments, net of the impact of offsetting positions was zero for both the three months ended March 31, 2020 and March 31, 2019. At March 31, 2020 , we pledged a total of $325 million related to derivative financial instruments, consisting of $284 million of cash collateral on derivative liabilities and $41 million of maintenance margin on centrally cleared derivatives and had a de-minimis obligation to return cash on derivative assets. We pledged a total of $63 million related to derivative financial instruments, consisting of $34 million of cash collateral on derivatives and $29 million of maintenance margin on centrally cleared derivatives and had a de-minimis obligation to return cash on derivative assets at December 31, 2019 . 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.

During the quarter ended March 31, 2020, we purchased $3 million of the Senior Notes on the open market. This has been accounted for as a debt extinguishment in accordance with applicable GAAP. Trust Preferred Securities We sponsor nine trust subsidiaries, which issued preferred stock to third party investors. We issued junior subordinated debt securities to those trusts, which we have included in long-term debt. The junior subordinated debt securities are the sole assets of those trusts. The trust preferred securities are callable by us at any time. Interest is payable quarterly; however, we may defer interest payments for up to 20 quarters without default or penalty. As of March 31, 2020 , we had no deferred interest.

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: Three Months Ended March 31, 2020 2019 (Dollars in millions, except share data) Net income applicable to common stockholders $ 46 $ 36 Weighted Average Shares Weighted average common shares outstanding 56,655,865 56,897,799 Effect of dilutive securities Stock-based awards 534,058 692,473 Weighted average diluted common shares $ 57,189,923 $ 57,590,272 Earnings per common share Basic earnings per common share $ 0.80 $ 0.64 Effect of dilutive securities Stock-based awards — (0.01 ) Diluted earnings per common share $ 0.80 $ 0.63

Legal Proceedings, Contingencie

Legal Proceedings, Contingencies and Commitments	3 Months Ended

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 origination, 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. At March 31, 2020 , 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 material 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 all of the following conditions which are evaluated quarterly and include: (a) the reversal of the DTA valuation allowance, which occurred at the end of 2013; (b) the repayment of the Fixed Rate Cumulative Perpetual Preferred Stock, Series C (the "TARP Preferred"), which occurred in July 2016; and (c) the Bank having a Tier 1 Leverage Capital Ratio of 11 percent or greater as filed in the Call Report with the OCC. No payment would be required until six months after the Bank files its Call Report with the OCC first reporting that its Tier 1 Leverage Capital Ratio was 11 percent or greater. If all other conditions were then satisfied, an initial annual payment would be due at that time. The next annual payment is only made if such other conditions continue to be satisfied, otherwise payments are delayed until all such conditions are met. Further, making such a payment must not violate any material banking regulatory requirement, and the OCC must not object in writing. Consistent with our business and regulatory requirements, Flagstar shall seek in good faith to fulfill the conditions, and will not undertake any conduct or fail to take any action the purpose of which is to frustrate or delay our ability to fulfill any of the above conditions. Additionally, if the Bank and Bancorp become party to a business combination in which the Bank or Bancorp represent less than 33.3 percent of the resulting company’s assets, annual payments must commence twelve months after the date of that business combination. The Settlement Agreement meets the definition of a financial instrument for which we elected the fair value option. We consider the assumptions a market participant would make to transfer the liability and evaluate the potential ways we might satisfy the Settlement Agreement and our estimates of the likelihood of these outcomes, which may change over time. The fair value of the liability is subject to significant uncertainty and is impacted by forecasted estimates of the timing of potential payments, some of which are impacted by inputs including estimates of equity, earnings, timing and amount of dividends and growth of the balance sheet and their related impacts on forecasted Tier 1 Leverage Capital Ratio discount rate, and the likelihood and types of potential business combinations, or any other means by which a payment could be made. For further information on the fair value of the liability, see Note 16 - Fair Value Measurements. Other litigation accruals At March 31, 2020 and December 31, 2019 , excluding the fair value liability relating to the DOJ liability, our total accrual for contingent liabilities and settled litigation was $3 million . Commitments The following table is a summary of the contractual amount of significant commitments: March 31, 2020 December 31, 2019 (Dollars in millions) Commitments to extend credit Mortgage loan commitments including interest-rate locks $ 8,345 $ 4,099 Warehouse loan commitments 2,258 1,944 Commercial and industrial commitments 741 1,107 Other commercial commitments 1,817 2,015 HELOC commitments 580 558 Other consumer commitments 272 175 Standby and commercial letters of credit 94 82 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. Since 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 in 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 commercial commitments. Conditional commitments issued under various terms to lend funds to business 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. Since 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 the estimate of probable credit losses inherent 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. See Note 4 - Loans Held-for-Investment for additional information. 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. Due to the condition of the Company at the time the former CEO’s employment ended, we believe that any payment under the SERP would be deemed to be a “Golden Parachute” payment and, therefore, is subject to certain banking regulations. As a result, we would need to make an application to the regulators to make a payment and certify to certain criteria. The Company does not believe that it can make such a certification. The former CEO has filed a lawsuit to compel us to make that certification and ultimately pay the liability. Final dispensation of the "SERP" is not within our control and the liability of $16 million at March 31, 2020

Regulatory Matters	Regulatory Matters Regulatory Capital We, along with the Bank, 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, 2020 and December 31, 2019 .

Fair Value Measurements

Fair Value Measurements	3 Months Ended

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 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 Statement of Financial Condition and by level in the valuation hierarchy.

(2) 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. (3) 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, 2020 Assets Loans held-for-investment Home equity $ 2 Discounted cash flows Discount rate 7.2% -10.8% (9.0%) (1) Mortgage servicing rights $ 223 Discounted cash flows Option adjusted spread 3.6% - 19.9% (5.6%) (1) Rate lock commitments (net) $ 169 Consensus pricing Origination pull-through rate 80.0% - 87.2% (81.2%) (1) Liabilities DOJ Liability $ (35 ) Discounted cash flows See description below See description below Contingent consideration $ (16 ) Discounted cash flows See description below See description below (2) Fair Value Valuation Technique Unobservable Input Range (Weighted Average) (Dollars in millions) December 31, 2019 Assets Loans held-for-investment Home equity $ 2 Discounted cash flows Discount rate 7.2% -10.8% (9.0%) (1) Mortgage servicing rights $ 291 Discounted cash flows Option adjusted spread 2.4% - 20.4% (5.3%) (1) Rate lock commitments (net) $ 34 Consensus pricing Origination pull-through rate 80.0% - 87.2% (81.5%) (1) Liabilities DOJ Liability $ (35 ) Discounted cash flows See description below See description below Contingent consideration $ (10 ) Discounted cash flows See description below See description below (2) (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. For March 31, 2020 and December 31, 2019 , the weighted average life (in years) for the entire MSR portfolio was 3.3 and 4.1 , respectively. DOJ Liability. The significant unobservable inputs used in the fair value measurement of the DOJ Liability are the discount rate, asset growth rate, return on assets, dividend rate and the 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. The DOJ Liability had a fair value adjustment of $25 million during the year ended December 31, 2019 . This reduced the liability to $35 million based on changes in the probability of potential ways we might be required to begin making DOJ Liability payments and our estimates of the likelihood of these outcomes. Our assessment of these outcomes reflect a reduced likelihood, and longer timing, for potential future payments. 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. Contingent consideration. The significant unobservable input used in the fair value of the contingent consideration is future forecasted target production volumes and forecasted profitability of the division. An increase or decrease to these inputs results in an increase or decrease of the liability. 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) March 31, 2020 Loans held-for-sale (2) $ 6 $ 6 $ — $ (1 ) Impaired loans held-for-investment (2) Residential first mortgage loans 15 — 15 (3 ) Repossessed assets (3) 10 — 10 (4 ) Totals $ 31 $ 6 $ 25 $ (8 ) December 31, 2019 Loans held-for-sale (2) $ 6 $ 6 $ — $ (1 ) Impaired loans held-for-investment (2) Residential first mortgage loans 14 — 14 (5 ) Repossessed assets (3) 10 — 10 (3 ) Totals $ 30 $ 6 $ 24 $ (9 ) (1) The fair values are determined at various dates during the three months ended March 31, 2020 and the year ended December 31, 2019 , respectively. (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, 2020 Impaired loans held-for-investment Loans held-for-investment $ 15 Fair value of collateral Loss severity discount 0% - 40% (6.3%) (1) Repossessed assets $ 10 Fair value of collateral Loss severity discount 0% - 100% (20.1%) (1) December 31, 2019 Impaired loans held-for-investment Loans held-for-investment $ 14 Fair value of collateral Loss severity discount 25% - 30% (25.9%) (1) Repossessed assets $ 10 Fair value of collateral Loss severity discount 0% - 100% (17.1%) (1) (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, 2020 Estimated Fair Value Carrying Value Total Level 1 Level 2 Level 3 (Dollars in millions) Assets Cash and cash equivalents $ 342 $ 342 $ 342 $ — $ — Securitized HFS loans not sold 2,058 $ 2,058 — 2,058 — Investment securities available-for-sale 2,446 2,446 — 2,446 — Investment securities held-to-maturity 554 569 — 569 — Loans held-for-sale 4,389 4,390 — 4,390 — Loans held-for-investment 13,795 13,801 — 10 13,791 Loans with government guarantees 814 788 — 788 — Mortgage servicing rights 223 223 — — 223 Federal Home Loan Bank stock 306 306 — 306 — Bank owned life insurance 351 351 — 351 — Repossessed assets 10 10 — — 10 Other assets, foreclosure claims 40 40 — 40 — Derivative financial instruments, assets 277 277 — 108 169 Liabilities Retail deposits Demand deposits and savings accounts $ (7,007 ) $ (6,570 ) $ — $ (6,570 ) $ — Certificates of deposit (2,138 ) (2,161 ) — (2,161 ) — Wholesale deposits (561 ) (575 ) — (575 ) — Government deposits (1,164 ) (1,160 ) — (1,160 ) — Custodial deposits (5,182 ) (5,165 ) — (5,165 ) — Federal Home Loan Bank advances (6,841 ) (6,870 ) — (6,870 ) — Long-term debt (493 ) (452 ) — (452 ) — DOJ Liability (35 ) (35 ) — — (35 ) Contingent consideration (16 ) (16 ) — — (16 ) Derivative financial instruments, liabilities (288 ) (288 ) — (288 ) — December 31, 2019 Estimated Fair Value Carrying Value Total Level 1 Level 2 Level 3 (Dollars in millions) Assets Cash and cash equivalents $ 426 $ 426 $ 426 $ — $ — Investment securities available-for-sale 2,116 2,116 — 2,116 — Investment securities held-to-maturity 598 599 — 599 — Loans held-for-sale 5,258 5,258 — 5,258 — Loans held-for-investment 12,129 12,031 — 10 12,021 Loans with government guarantees 736 707 — 707 — Mortgage servicing rights 291 291 — — 291 Federal Home Loan Bank stock 303 303 — 303 — Bank owned life insurance 349 349 — 349 — Repossessed assets 10 10 — — 10 Other assets, foreclosure claims 45 45 — 45 — Derivative financial instruments, assets 62 88 — 54 34 Liabilities Retail deposits Demand deposits and savings accounts $ (6,811 ) $ (6,050 ) $ — $ (6,050 ) $ — Certificates of deposit (2,353 ) (2,368 ) — (2,368 ) — Wholesale deposits (633 ) (640 ) — (640 ) — Government deposits (1,213 ) (1,156 ) — (1,156 ) — Custodial deposits (4,136 ) (4,066 ) — (4,066 ) — Federal Home Loan Bank advances (4,815 ) (4,816 ) — (4,816 ) — Long-term debt (496 ) (462 ) — (462 ) — DOJ Liability (35 ) (35 ) — — (35 ) Contingent consideration (10 ) (10 ) — — (10 ) Derivative financial instruments, liabilities (18 ) (44 ) — (43 ) (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, 2020 2019 (Dollars in millions) Assets Loans held-for-sale Net gain (loss) on loan sales $ 234 $ 79 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, 2020 December 31, 2019 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 $ 4 $ 3 $ (1 ) $ 3 $ 3 $ — Loans held-for-investment 5 4 (1 ) 5 4 (1 ) Total nonaccrual loans $ 9 $ 7 $ (2 ) $ 8 $ 7 $ (1 ) Other performing loans Loans held-for-sale $ 4,151 $ 4,362 $ 211 $ 5,057 $ 5,216 $ 159 Loans held-for-investment 8 8 — 8 8 — Total other performing loans $ 4,159 $ 4,370 $ 211 $ 5,065 $ 5,224 $ 159 Total loans Loans held-for-sale $ 4,155 $ 4,365 $ 210 $ 5,060 $ 5,219 $ 159 Loans held-for-investment 13 12 (1 ) 13 12 (1 ) Total loans $ 4,168 $ 4,377 $ 209 $ 5,073 $ 5,231 $ 158 Liabilities DOJ Liability (1) $ (118 ) $ (35 ) $ 83 $ (118 ) $ (35 ) $ 83 (1) We are obligated to pay $118 million in installment payments upon meeting certain performance conditions, as described in Note 15

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. As a result of Management's evaluation of our segments, effective January 1, 2020, certain departments have been re-aligned between the Community Banking and Mortgage Originations. Specifically, a majority of the residential mortgage HFI portfolio is now part of the Mortgage Origination segment. The income and expenses relating to these changes are reflected in our financial statements and all prior period segment financial information has been recast to conform to the current presentation. 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, Warehouse Lending and LHFI Portfolio groups. Products offered through these groups include checking accounts, savings accounts, money market accounts, certificates of deposit, consumer loans, commercial loans, commercial real estate loans, equipment finance and leasing, 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 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 Origination 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 within LHFI. The interest income on LHFI, excluding residential first mortgages, newly originated home equity products, and a loss on sales for the purchase of these loans is recognized in the Community Banking segment. 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 provision (benefit) for income taxes, are fully allocated to each operating 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, 2020 Community Banking Mortgage Originations Mortgage Servicing Other (1) Total (Dollars in millions) Summary of Operations Net interest income $ 104 $ 42 $ 4 $ (2 ) $ 148 Provision (benefit) for credit losses 8 (3 ) — 9 $ 14 Net interest income after provision (benefit) for credit losses 96 45 4 (11 ) 134 Net gain on loan sales — 90 — — 90 Loan fees and charges — 17 9 — 26 Loan administration (expense) income (1 ) (7 ) 36 (16 ) 12 Net return on mortgage servicing rights — 6 — — 6 Other noninterest income 16 1 — 6 23 Total noninterest income 15 107 45 (10 ) 157 Compensation and benefits 27 31 10 34 102 Commissions 1 28 — — 29 Loan processing expense 2 10 7 1 20 Other noninterest expense 44 26 19 (5 ) 84 Total noninterest expense 74 95 36 30 235 Income before indirect overhead allocations and income taxes 37 57 13 (51 ) 56 Indirect overhead allocation Income (expense) (9 ) (12 ) (5 ) 26 — Provision (benefit) for income taxes 6 9 2 (7 ) 10 Net income (loss) $ 22 $ 36 $ 6 $ (18 ) $ 46 Intersegment (expense) revenue $ (6 ) $ 1 $ 8 $ (3 ) $ — Average balances Loans held-for-sale $ — $ 5,248 $ — $ — $ 5,248 Loans with government guarantees — 811 — — $ 811 Loans held-for-investment (2) 8,898 2,895 — 30 $ 11,823 Total assets 9,387 9,817 48 4,161 $ 23,413 Deposits 10,434 — 4,777 584 $ 15,795 (1) Includes offsetting adjustments made to reclassify income and expenses relating to operating leases and custodial deposits for subservicing clients.

Accounting Policies [Abstract]
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 - In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which alters the current method for recognizing credit losses within the reserve account. The new guidance requires financial assets to be presented at the net amount expected to be collected (i.e. net of expected credit losses). 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. 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. 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 ASC 326: January 1, 2020 As Reported Under ASC 326 Pre-ASC 326 Adoption Impact of ASC 326 Adoption (Dollars in millions) Assets: Allowance for loan losses $ 130 $ 107 $ 23 Liabilities: Reserve for unfunded commitments $ 10 $ 3 $ 7 We adopted the following accounting standard updates (ASU) during 2020, none of which had a material impact to our financial statements: Standard Description Effective Date 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting March 12, 2020 2020-03 Codification Improvements to Financial Instruments January 1, 2020 2020-02 Financial Instruments-Credit Losses (Topic 326) and Leases (Topic 842)-Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842) (SEC Update) February 6, 2020 2018-15 Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) January 1, 2020 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement January 1, 2020 2017-04 Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment January 1, 2020 Insignificant Accounting Standards Issued But Not Yet Adopted The following ASUs have been issued and are not expected to have a material impact on our Consolidated Financial Statements and/or significant accounting policies: Standard Description Effective Date 2019-12 Simplifying the Accounting for Income Taxes January 1, 2021

Accounting Policies [Abstract]
Credit Quality	Credit Quality We utilize an internal risk rating system which is applied to all consumer and commercial loans. Descriptions of our internal 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. They 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 non-accrual 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 non-accrual. 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, but, 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, and includes consumer 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 Substandard.
Fair Value Measurement	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.
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 - In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which alters the current method for recognizing credit losses within the reserve account. The new guidance requires financial assets to be presented at the net amount expected to be collected (i.e. net of expected credit losses). 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.
