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 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, which is available on our website, flagstar.com, and on the SEC website, at sec.gov.

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 which represented 94 percent of our AFS portfolio as of June 30, 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 OCI. We had no unrealized credit losses as of June 30, 2020 and December 31, 2019. We separately evaluate our HTM debt securities for any credit losses. As of June 30, 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. 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 $6 million at both June 30, 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 $9 million and $359 million of AFS securities, which were comprised of U.S. government sponsored agency MBS, certificate of deposits, and corporate debt obligations during the three and six months ended June 30, 2020. We purchased $7 million and $23 million of AFS securities, which were comprised of U.S. government sponsored agency MBS, certificate of deposits, and corporate debt obligations during the three and six months ended June 30, 2019, respectively. In addition, we retained $18 million of passive interests in our own private MBS during the six months ended June 30, 2020. We did not retain any interest in our own private MBS during the three months ended June 30, 2020 or both the three and six months ended June 30, 2019. There were no sales of AFS securities during both the three and six months ended June 30, 2020. There were $432 million in sales of AFS securities during the three and six months ended June 30, 2019, respectively. These sales resulted in a gain of $7 million, reported in other noninterest income in the Consolidated Statements of Operations. These sales did not include 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 and six months ended June 30, 2020 and June 30, 2019. The following table summarizes the unrealized loss positions on available-for-sale and held-to-maturity investment securities, by duration of the unrealized loss: Unrealized Loss Position with Unrealized Loss Position with Fair Value Number of Securities Unrealized Loss Fair Number of Unrealized (Dollars in millions) June 30, 2020 Available-for-sale securities Agency - Commercial $ 4 1 $ — $ 8 1 $ — Municipal obligations $ — 1 $ — $ — — $ — Corporate debt obligations $ — — $ — $ 23 7 $ (1) Other mortgage-backed securities $ — — $ — $ — 1 $ — Held-to-maturity securities Agency - Residential $ — — $ — $ 9 2 $ — 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 Fair Weighted Average Amortized Fair Weighted Average (Dollars in millions) June 30, 2020 Due in one year or less $ 4 $ 4 2.07 % $ — $ — — % Due after one year through five years 10 10 2.73 % 8 9 2.51 % Due after five years through 10 years 110 112 4.19 % 8 8 2.30 % Due after 10 years 2,144 2,222 2.38 % 480 499 2.38 % Total $ 2,268 $ 2,348 $ 496 $ 516 We pledge investment securities, primarily agency collateralized and municipal taxable mortgage obligations, to collateralize lines of credit and/or borrowings. At June 30, 2020 and December 31, 2019, we had pledged investment securities of $179 million and $874 million, 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 mortgage-backed securities. LHFS totaled $5.6 billion and $5.3 billion at June 30, 2020 and December 31, 2019, respectively. For the three and six months ended June 30, 2020 we had net gain on loan sales associated with LHFS of $303 million and $392 million as compared to $75 million and $122 million for the three and six months ended June 30, 2019. At June 30, 2020 and December 31, 2019, $17 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: Revolving Loans Converted to Term Loans Amortized Cost Basis Term Loans Revolving Loans Amortized Cost Basis Total December 31, 2019 Amortized Cost Basis by Origination Year As of June 30, 2020 2020 2019 2018 2017 2016 Prior Commercial Loans (Dollars in million) Commercial real estate Pass $ 184 $ 950 $ 477 $ 486 $ 353 $ 286 $ (1) $ — $ 2,735 $ 2,794 Watch 23 32 88 33 38 36 — — 250 24 Special mention — — 3 20 — — — — 23 5 Substandard — — 3 5 — — — — 8 5 Commercial and industrial Pass 119 580 248 317 113 110 22 — 1,509 1,533 Watch 1 2 10 — — — 1 — 14 72 Special mention 1 12 4 14 — 6 — — 37 24 Substandard 21 — 10 4 — — — — 35 5 Payroll protection program Pass 373 — — — — — — — 373 — Warehouse Pass — — — — — — 4,942 — 4,942 2,556 Watch — — — — — — 255 — 255 189 Special mention — — — — — — 35 — 35 15 Substandard — — — — — — — — — — Total commercial loans $ 722 $ 1,576 $ 843 $ 879 $ 504 $ 438 $ 5,254 $ — $ 10,216 $ 7,222 " id="sjs-B4" xml:space="preserve">Loans Held-for-Investment We classify loans that we have the intent and ability to hold for the foreseeable future or until maturity as LHFI. We 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 loans held-for-investment totaled $38.8 million at June 30, 2020 and $36.9 million at December 31, 2019 and was reported in other assets on the Consolidated Statements of Financial Condition. The following table presents our loans held-for-investment: June 30, 2020 December 31, 2019 (Dollars in millions) Consumer loans Residential first mortgage $ 2,716 $ 3,154 Home equity 978 1,024 Other 898 729 Total consumer loans 4,592 4,907 Commercial loans Commercial real estate 3,016 2,828 Commercial and industrial 1,968 1,634 Warehouse lending 5,232 2,760 Total commercial loans 10,216 7,222 Total loans held-for-investment $ 14,808 $ 12,129 The following table presents the UPB of our loan sales and purchases in the loans held-for-investment portfolio: Six Months Ended June 30, 2020 2019 (Dollars in millions) Loans Sold (1) Performing loans $ 38 $ 139 Total loans sold $ 38 $ 139 Net gain associated with loan sales (2) $ — $ 2 Loans Purchased Home equity $ — $ 149 Other consumer 63 51 Total loans purchased $ 63 $ 200 Premium associated with loans purchased $ — $ 7 (1) Upon a change in our intent, the loans were transferred to LHFS and subsequently sold. (2) Recorded in net gain on loan sales on Consolidated Statements of Operations. We have pledged certain LHFI, LHFS, and loans with government guarantees to collateralize lines of credit and/or borrowings with the FHLB of Indianapolis and the FRB of Chicago. At June 30, 2020 we had pledged loans of $11.6 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 June 30, 2020, we estimated losses over a two-year reasonable and supportable forecast period using macroeconomic scenarios before reverting economic variables over a one-year period to their long-term historical averages on a straight-line basis. As of June 30, 2020, we utilized the Moody’s June 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. The resulting composite forecast for the second quarter of 2020 was worse than the scenario used in the first quarter 2020. Unemployment ends the year at 10 percent and recovers only slightly in 2021. GDP recovers only slightly by the end of the year from current levels and does not return to the pre-COVID level until mid-2022. HPI decreases 2 percent from early 2020 through 2021. The worsening of our economic forecast increased the ACL by $31 million from March 31, 2020. In addition to this increase, we judgmentally increased the qualitative reserves by $39 million primarily in our CRE and C&I portfolios, guided by the model output from Moody's adverse scenario and our judgment relating to industries and borrowers we believe could be more exposed to the stressful conditions in our forecast. In addition, we reviewed our loans in deferral status and proactively downgraded loans totaling approximately $180 million UPB from "pass" status during the quarter, resulting in an increase of $24 million to the ACL. This resulted in an increase to our reserves of approximately $98 million during the second quarter, which includes an increase in our reserves for unfunded commitments of $1 million. The following table presents changes in the allowance for loan losses, by class of loan: Residential Home Equity Other Commercial Commercial Warehouse Total (Dollars in millions) Three Months Ended June 30, 2020 Beginning balance $ 46 $ 23 $ 16 $ 28 $ 18 $ 1 $ 132 Provision 16 5 19 55 5 — 100 Charge-offs (2) (1) (2) — — — (5) Recoveries — 1 1 — — — 2 Ending allowance balance $ 60 $ 28 $ 34 $ 83 $ 23 $ 1 $ 229 Three Months Ended June 30, 2019 Beginning balance $ 35 $ 16 $ 4 $ 36 $ 30 $ 6 $ 127 Provision (benefit) (8) — 3 (1) 24 (1) 17 Charge-offs (1) — (3) — (31) — (35) Recoveries — — 1 — — — 1 Ending allowance balance $ 26 $ 16 $ 5 $ 35 $ 23 $ 5 $ 110 Six Months Ended June 30, 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 16 2 20 59 7 — 104 Charge-offs (3) (2) (3) — — — (8) Recoveries — 2 1 — — — 3 Ending allowance balance $ 60 $ 28 $ 34 $ 83 $ 23 $ 1 $ 229 Six Months Ended June 30, 2019 Beginning balance $ 38 $ 15 $ 3 $ 48 $ 18 $ 6 $ 128 Provision (benefit) (10) — 5 (13) 36 (1) 17 Charge-offs (2) — (4) — (31) — (37) Recoveries — 1 1 — — — 2 Ending allowance balance $ 26 $ 16 $ 5 $ 35 $ 23 $ 5 $ 110 (1) Includes loans with government guarantees. The allowance for loan losses was $229 million at June 30, 2020 and $110 million at June 30, 2019. The increase in the allowance is reflective of the adoption of CECL and changes in the economic forecast used in the ACL models 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 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 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) (Dollars in millions) June 30, 2020 Consumer loans Residential first mortgage $ 6 $ 5 $ 27 $ 38 $ 2,678 $ 2,716 Home equity 1 — 5 6 972 978 Other 2 1 1 4 894 898 Total consumer loans 9 6 33 48 4,544 4,592 Commercial loans Commercial real estate — — — — 3,016 3,016 Commercial and industrial (1) — — — — 1,968 1,968 Warehouse lending — — — — 5,232 5,232 Total commercial loans — — — — 10,216 10,216 Total loans (2) $ 9 $ 6 $ 33 $ 48 $ 14,760 $ 14,808 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 $5 million and $4 million of past due loans accounted for under the fair value option as of June 30, 2020 and December 31, 2019, respectively. (3) Collateral dependent loans totaled $63 million at June 30, 2020 and $54 million at December 31, 2019, respectively. The majority of these loans are secured by real estate. (4) The interest income recognized on impaired loans was $1 million and less than $1 million at June 30, 2020 and December 31, 2019, respectively. Interest income is recognized on nonaccrual loans using a cash basis method. The interest income recognized on impaired loans was $1 million and less than $1 million at June 30, 2020 and December 31, 2019, respectively. At June 30, 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 Consolidated Statements of Financial Condition and was $21 million as of June 30, 2020, compared to $3 million as of June 30, 2019. The increase in the reserve is reflective of the adoption of CECL which required 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. 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 offered our consumer and commercial customers principal and interest payment deferrals and extensions. We considered these programs in the context of whether or not the short-term modifications of these loans would constitute a TDR. We considered the CARES Act, interagency guidance and related guidance from the FASB, which provided that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not required to be accounted for as TDRs. As a result, we have determined that these loans are not TDRs. The following table provides a summary of TDRs by type and performing status: TDRs Performing Nonperforming Total (Dollars in millions) June 30, 2020 Consumer loans Residential first mortgage $ 20 $ 8 $ 28 Home equity 15 2 17 Commercial Real Estate 5 — 5 Total TDRs (1)(2) $ 40 $ 10 $ 50 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 $4 million and $8 million at June 30, 2020 and December 31, 2019, respectively. (2) Includes $2 million of TDR loans accounted for under the fair value option at June 30, 2020 and December 31, 2019.

(2) Home equity post-modification UPB reflects write downs. (3) Includes loans carried at the fair value option. There was one residential first mortgage loan modified in the previous 12 months that subsequently defaulted during the three and six months ended June 30, 2020. There were no residential first mortgage loans modified in the previous 12 months that subsequently defaulted during the three and six months ended June 30, 2019. The increase in allowance at modification was less than $1 million for the three months ended June 30, 2020 and June 30, 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. 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.

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: Revolving Loans Converted to Term Loans Amortized Cost Basis Term Loans Revolving Loans Amortized Cost Basis Total December 31, 2019 Amortized Cost Basis by Origination Year As of June 30, 2020 2020 2019 2018 2017 2016 Prior Commercial Loans (Dollars in million) Commercial real estate Pass $ 184 $ 950 $ 477 $ 486 $ 353 $ 286 $ (1) $ — $ 2,735 $ 2,794 Watch 23 32 88 33 38 36 — — 250 24 Special mention — — 3 20 — — — — 23 5 Substandard — — 3 5 — — — — 8 5 Commercial and industrial Pass 119 580 248 317 113 110 22 — 1,509 1,533 Watch 1 2 10 — — — 1 — 14 72 Special mention 1 12 4 14 — 6 — — 37 24 Substandard 21 — 10 4 — — — — 35 5 Payroll protection program Pass 373 — — — — — — — 373 — Warehouse Pass — — — — — — 4,942 — 4,942 2,556 Watch — — — — — — 255 — 255 189 Special mention — — — — — — 35 — 35 15 Substandard — — — — — — — — — — Total commercial loans $ 722 $ 1,576 $ 843 $ 879 $ 504 $ 438 $ 5,254 $ — $ 10,216 $ 7,222

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 $30 million and $45 million, at June 30, 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 June 30, 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 - Fair Value Measurements, for additional information.

Mortgage Servicing Rights

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 June 30, Six Months Ended June 30, 2020 2019 2020 2019 (Dollars in millions) Balance at beginning of period $ 223 $ 278 $ 291 $ 290 Additions from loans sold with servicing retained 84 97 124 164 Reductions from sales (10) — (46) (45) Decrease in MSR fair value due to pay-offs, pay-downs, run-off, model changes, and other (1) (27) (19) (49) (30) Changes in estimates of fair value due to interest rate risk (1) (2) (9) (40) (59) (63) Fair value of MSRs at end of period $ 261 $ 316 $ 261 $ 316 (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: June 30, 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 6.73 % $ 256 $ 251 5.34 % $ 284 $ 280 Constant prepayment rate 11.78 % $ 239 $ 220 10.59 % $ 271 $ 257 Weighted average cost to service per loan $ 83.08 $ 258 $ 255 $ 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.

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 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 and residential first mortgage loans held for investment using the last-of-layer method. Cash flows and the profit impact associated with designated hedges are reported in the same category as the underlying hedged item. We have also designated certain interest rate swaps as cash flow hedges on LIBOR based variable interest payments on certain custodial deposits. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense in the same period in which the hedge transaction is recognized in earnings. At June 30, 2020, we had $10 million (net-of-tax) of unrealized losses on derivatives classified as cash flow hedges recorded in accumulated other comprehensive income. 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 $3 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 June 30, 2020.

Losses of $1 million on cash flow hedging relationships of custodial deposits were reclassified from AOCI into loan administration income during the three and six months ended June 30, 2020. The gains and losses on fair value hedging relationships of both AFS securities and HFI residential first mortgages for the three and six months ended June 30, 2020 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 $2,039 million at June 30, 2020 and $287 million at December 31, 2019 of which $8 million and $1 million, respectively, were due to the fair value hedge relationship. The closed portfolio of AFS securities designated in this last layer method hedge was $1,968 million par (amortized cost of $1,965 million) at June 30, 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 June 30, 2020 and December 31, 2019, respectively. The fair value basis adjustment on our hedged fair HFI residential first mortgages is included in loans held-for-investment on our Consolidated Statements of Financial Condition. The carrying amount of our hedged loans was $267 million at June 30, 2020 of which $1 million was due to the fair value hedge relationship. There were no hedged HFI residential first mortgages at December 31, 2019. We have designated $100 million of this closed portfolio of loans in a hedging relationship as of June 30, 2020. At June 30, 2020, we pledged a total of $107 million related to derivative financial instruments, consisting of $71 million of cash collateral on derivative liabilities and $36 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.

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 June 30, Six Months Ended June 30, 2020 2019 2020 2019 (Dollars in millions, except share data) Net income applicable to common stockholders $ 116 $ 61 $ 161 $ 97 Weighted Average Shares Weighted average common shares outstanding 56,790,642 56,446,077 56,723,254 56,670,690 Effect of dilutive securities Stock-based awards 333,064 615,745 433,561 651,823 Weighted average diluted common shares $ 57,123,706 $ 57,061,822 $ 57,156,815 $ 57,322,513 Earnings per common share Basic earnings per common share $ 2.04 $ 1.08 $ 2.85 $ 1.71 Effect of dilutive securities Stock-based awards (0.01) (0.02) (0.02) (0.02) Diluted earnings per common share $ 2.03 $ 1.06 $ 2.83 $ 1.69

Banking and Thrift, Other Disclosures [Abstract]
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 June 30, 2020 and December 31, 2019. The following tables present the regulatory capital ratios as of the dates indicated: Flagstar Bancorp Actual For Capital Adequacy Purposes Well-Capitalized Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio (Dollars in millions) June 30, 2020 Tier 1 capital (to adjusted avg. total assets) $ 2,021 7.8 % $ 1,042 4.0 % $ 1,301 5.0 % Common equity Tier 1 capital (to RWA) $ 1,781 9.1 % $ 880 4.5 % $ 1,272 6.5 % Tier 1 capital (to RWA) $ 2,021 10.3 % $ 1,174 6.0 % $ 1,565 8.0 % Total capital (to RWA) $ 2,214 11.3 % $ 1,565 8.0 % $ 1,956 10.0 % December 31, 2019 Tier 1 capital (to adjusted avg. total assets) $ 1,720 7.6 % $ 909 4.0 % $ 1,136 5.0 % Common equity Tier 1 capital (to RWA) $ 1,480 9.3 % $ 715 4.5 % $ 1,033 6.5 % Tier 1 capital (to RWA) $ 1,720 10.8 % $ 953 6.0 % $ 1,271 8.0 % Total capital (to RWA) $ 1,830 11.5 % $ 1271 8.0 % $ 1,589 10.0 % Flagstar Bank Actual For Capital Adequacy Purposes Well-Capitalized Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio (Dollars in millions) June 30, 2020 Tier 1 capital (to adjusted avg. total assets) $ 1,969 7.6 % $ 1,041 4.0 % $ 1,301 5.0 % Common equity Tier 1 capital (to RWA) $ 1,969 10.1 % $ 880 4.5 % $ 1,271 6.5 % Tier 1 capital (to RWA) $ 1,969 10.1 % $ 1,174 6.0 % $ 1,565 8.0 % Total capital (to RWA) $ 2,161 11.0 % $ 1,565 8.0 % $ 1,956 10.0 % December 31, 2019 Tier 1 capital (to adjusted avg. total assets) $ 1,752 7.7 % $ 909 4.0 % $ 1,136 5.0 % Common equity Tier 1 capital (to RWA) $ 1,752 11.0 % $ 714 4.5 % $ 1,032 6.5 % Tier 1 capital (to RWA) $ 1,752 11.0 % $ 952 6.0 % $ 1,270 8.0 % Total capital (to RWA) $ 1,862 11.7 % $ 1,270 8.0 % $ 1,587 10.0 %

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 June 30, 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 June 30, 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 $6 million and $3 million, respectively. Commitments The following table is a summary of the contractual amount of significant commitments: June 30, 2020 December 31, 2019 (Dollars in millions) Commitments to extend credit Mortgage loan commitments including interest-rate locks $ 11,362 $ 4,099 Warehouse loan commitments 2,718 1,944 Commercial and industrial commitments 960 1,107 Other commercial commitments 1,736 2,015 HELOC commitments 557 558 Other consumer commitments 478 175 Standby and commercial letters of credit 100 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. 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 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 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 Measurements

Fair Value Measurements	6 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.

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) June 30, 2020 Assets Loans held-for-investment Home equity $ 2 Discounted cash flows Discount rate 7.2% -10.8% (9.0%) 17.3% - 25.9% (21.6%) 2.0%-3.0% (2.5%) (1) Mortgage servicing rights $ 261 Discounted cash flows Option adjusted spread 3.6% - 20.1% (6.7%) 0% - 14.8% (11.8%) $67 - $95 ($83) (1) Rate lock commitments (net) $ 205 Consensus pricing Origination pull-through rate 80.0% - 87.2% (81.4%) (1) Liabilities DOJ Liability $ (35) Discounted cash flows See description below See description below Contingent consideration $ (27) 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%) 13.0% - 19.5% (16.2%) 2.7%-4.0% (3.3%) (1) Mortgage servicing rights $ 291 Discounted cash flows Option adjusted spread 2.4% - 20.4% (5.3%) 0% - 12.3% (10.6%) $67 - $95 ($84) (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 June 30, 2020 and December 31, 2019, the weighted average life (in years) for the entire MSR portfolio was 3.6 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 Losses (Dollars in millions) June 30, 2020 Loans held-for-sale (2) $ 6 $ 6 $ — $ (1) Impaired loans held-for-investment (2) Residential first mortgage loans 21 — 21 (3) Repossessed assets (3) 7 — 7 (4) Totals $ 34 $ 6 $ 28 $ (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 dependent upon when certain conditions were met requiring fair value measurement.

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 Originations 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 and Warehouse Lending. 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 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.

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 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.
