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, 2016 , which is available on our website, at flagstar.com, and on the SEC website, at sec.gov.

We evaluate AFS and HTM investment securities for other than temporary impairment on a quarterly basis. An OTTI is considered to have occurred when the fair value of a debt security is below its amortized costs and we (1) have the intent to sell the security, (2) will more likely than not be required to sell the security before recovery of its amortized cost, or (3) do not expect to recover the entire amortized cost basis of the security. Investments that have an OTTI are written down through a charge to earnings for the amount representing the credit loss on the security. Gains and losses related to all other factors are recognized in other comprehensive income (loss). During the three and nine months ended September 30, 2017 and September 30, 2016 , we had no OTTI losses. Available-for-sale securities Securities available-for-sale are carried at fair value, with unrealized gains and losses, to the extent they are temporary in nature, and are reported as a component of other comprehensive income. We purchased $300 million and $600 million of AFS securities, which included U.S. government sponsored agency MBS, corporate debt obligations, and municipal obligations, during the three and nine months ended September 30, 2017 , respectively. We purchased $136 million and $203 million of AFS securities, which included U.S. government sponsored agencies comprised of MBS and municipal obligations, during the three and nine months ended September 30, 2016 , respectively. Gains on sales of AFS securities are reported in other noninterest income in the Consolidated Statements of Operations. We sold $227 million and $289 million of AFS securities during the three and nine months ended September 30, 2017 , respectively, which did not include those AFS securities related to mortgage loans that had been securitized for sale in the normal course of business. These sales resulted in a realized gain of $2 million and $3 million during the three and nine months ended September 30, 2017 , respectively. During the three and nine months ended September 30, 2016 , there were $115 million and $290 million , respectively, in sales of AFS securities, which did not include those related to mortgage loans that had been securitized for sale in the normal course of business. These sales resulted in a realized gain of $3 million and $4 million during the three and nine months ended September 30, 2016 , respectively. 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 of HTM securities during the three and nine months ended September 30, 2017 . During the three and nine months ended September 30, 2016 , we purchased zero and $15 million of HTM securities, respectively. There were no sales of HTM securities during the three and nine months ended September 30, 2017 and September 30, 2016 .

Receivables Held-for-sale [Abstract]
Loans Held-for-Sale	Loans Held-for-Sale The majority of our mortgage loans originated as LHFS are sold into the secondary market by securitizing the loans into agency mortgage backed securities, through retail mortgage-backed securitizations or on a whole loan basis. At September 30, 2017 and December 31, 2016 , LHFS totaled $4.9 billion and $3.2 billion , respectively. For the three and nine months ended September 30, 2017 , we had net gains on loan sales associated with LHFS of $75 million and $189 million , respectively. During the three and nine months ended September 30, 2016 , excluding the gains from the sale of mortgage loans transferred from loans held-for-investment, we had $94 million and $244 million , respectively, of net gains on loan sales associated with LHFS. At both September 30, 2017 and December 31, 2016 , $32 million of LHFS were recorded at lower of cost or fair value. The remainder of the loans in the portfolio are recorded at fair value as we have elected the fair value option for such loans.

During the nine months ended September 30, 2017 , we sold performing and nonperforming consumer loans with UPB of $103 million , of which $25 million were nonperforming. Upon a change in our intent, the loans were transferred to LHFS and subsequently sold resulting in a gain of $1 million during the nine months ended September 30, 2017 , which is recorded in net gain on loan sales on the Consolidated Statements of Operations. During the nine months ended September 30, 2016 , we sold performing and nonperforming consumer loans with UPB totaling $1.3 billion , of which $110 million were nonperforming. Upon a change in our intent, the loans were transferred to LHFS and subsequently sold resulting in a net gain on sale of $12 million , during the nine months ended September 30, 2016 , which is recorded in net gain on loan sales on the Consolidated Statements of Operations.

At September 30, 2017 and December 31, 2016 , we had pledged loans of $7.7 billion and $5.3 billion , respectively. Allowance for Loan Losses We determine the estimate of the ALLL on at least a quarterly basis. Refer to Note 1 - Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies to the consolidated financial statements in the Annual Report on Form 10-K for the year ended December 31, 2016 for a description of the methodology. The ALLL, other than for loans that have been identified for individual evaluation for impairment, is determined on a loan pool basis by grouping loan types with common risk characteristics to determine our best estimate of incurred losses.

(2) Excludes loans carried under the fair value option. Loans are considered to be past due when any payment of principal or interest is 30 days past the scheduled payment date. While it is the goal of management to collect on loans, we attempt to work out a satisfactory repayment schedule or modification with past due borrowers and will undertake foreclosure proceedings if the delinquency is not satisfactorily resolved. Our practices regarding past due loans are designed to both assist borrowers in meeting their contractual obligations and minimize losses incurred by the Bank. We cease the accrual of interest on all classes of consumer and commercial loans upon the earlier of, becoming 90 days past due, or when doubt exists as to the ultimate collection of principal or interest (classified as nonaccrual or 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. Interest income is recognized on nonaccrual loans using a cash basis method. Interest that would have been accrued on impaired loans totaled zero and $1 million during the three and nine months ended September 30, 2017 , respectively, and $1 million and $2 million during the three and nine months ended September 30, 2016 , respectively. At September 30, 2017 and December 31, 2016 , we had no loans 90 days past due and still accruing interest.

Troubled Debt Restructurings We may modify certain loans in both our consumer and commercial loan portfolios to retain customers or to maximize collection of the outstanding loan balance. We have programs designed to assist borrowers by extending payment dates or reducing the borrower's contractual payments. All loan modifications are made on a case-by-case basis. Our standards relating to loan modifications consider, among other factors, minimum verified income requirements, cash flow analysis, and collateral valuations. TDRs result in those instances in which a borrower demonstrates financial difficulty and for which a concession has been granted, which includes reductions of interest rate, extensions of amortization period, principal and/or interest forgiveness and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral. These loans are classified as nonperforming TDRs if the loan was nonperforming prior to the restructuring, or based upon the results of a contemporaneous credit evaluation. Such loans will continue on nonaccrual status until the borrower has established a willingness and ability to make the restructured payments for at least six months, after which they will be classified as performing TDRs and begin to accrue interest. Performing and nonperforming TDRs remain impaired as interest and principal will not be received in accordance with the original contractual terms of the loan agreement. Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, but may give rise to potential incremental losses. We measure impairments using a discounted cash flow method for performing TDRs and measure impairment based on collateral values for nonperforming TDRs. The following table provides a summary of TDRs by type and performing status: TDRs Performing Nonperforming Total (Dollars in millions) September 30, 2017 Consumer loans (1) Residential first mortgage $ 20 $ 11 $ 31 Home equity 26 4 30 Total TDRs (2) $ 46 $ 15 $ 61 December 31, 2016 Consumer loans (1) Residential first mortgage $ 22 $ 11 $ 33 Home equity 45 7 52 Total TDRs (2) $ 67 $ 18 $ 85 (1) The ALLL on consumer TDR loans totaled $12 million and $9 million at September 30, 2017 and December 31, 2016 , respectively.

(2) Home equity post-modification unpaid principal balance reflects write downs. (3) Includes loans carried at the fair value option. There was one residential first mortgage loan with a UPB of less than $1 million that was modified in the previous 12 months, which has subsequently defaulted during the three and nine months ended September 30, 2017 as compared to three home equity loans with a UPB of less than $1 million for each class which subsequently defaulted during the three months ended September 30, 2016 and one residential first mortgage loan and seven home equity loans with a UPB of less than $1 million for each class which subsequently defaulted during the nine months ended September 30, 2016 . There was no increase or decrease in the allowance associated with these TDRs at subsequent default. All TDR classes within the consumer and commercial portfolios are considered subsequently defaulted when greater than 90 days past due. Subsequent default is defined as a payment re-defaulted within 12 months of the restructuring date.

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. Nonperforming loans are classified as either substandard, doubtful or loss. 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. Because of high probability of loss, non-accrual accounting treatment is required for doubtful assets. 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 this basically worthless asset even though partial recovery may be affected in the future. Commercial Loans Management conducts periodic examinations which serve as an independent verification of the accuracy of the ratings assigned. 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. Consumer Loans The same rating principles are used for consumer and commercial loans, but the principles are applied differently for 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 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.

Loans and Leases Receivable Disclosure [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 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 ALLL on residential first mortgages. At September 30, 2017 and December 31, 2016 , respectively, loans with government guarantees totaled $253 million and $365 million . At September 30, 2017 and December 31, 2016 , respectively, repossessed assets and the associated claims recorded in other assets totaled $92 million and $135 million .

Mortgage Servicing Rights

Mortgage Servicing Rights	9 Months Ended

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. The primary risk associated with MSRs is the potential reduction in fair value as a result of higher than anticipated prepayments due to loan refinancing prompted, in part, by declining interest rates or government intervention. Conversely, these assets generally increase in value in a rising interest rate environment to the extent that prepayments are slower than previously 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, See Note 8 - Derivative Financial Instruments, regarding the derivative instruments utilized to manage our MSR risks. The following table presents changes in the carrying value of residential first mortgage MSRs, accounted for at fair value: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 (Dollars in millions) Balance at beginning of period $ 184 $ 301 $ 335 $ 296 Additions from loans sold with servicing retained 75 51 178 173 Reductions from sales (4 ) (17 ) (260 ) (41 ) Changes in fair value due to (1) Decrease in MSR due to payoffs, pay-downs and run-off (5 ) (19 ) (15 ) (45 ) Changes in estimates of fair value (2) (4 ) (14 ) 8 (81 ) Balance at end of period $ 246 $ 302 $ 246 $ 302 (1) Changes in fair value are included within net return (loss) on MSRs on the Consolidated Statements of Operations. (2) Represents estimated MSR value change resulting primarily from market-driven changes. 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. The significant assumptions used in the fair value measurement of the MSRs are option adjusted spread and prepayment rate. Significant increases (decreases) in both of these assumptions in isolation would result in a significantly lower (higher) fair value measurement. September 30, 2017 December 31, 2016 Fair value after Fair value after Actual 10% adverse change 20% adverse change Actual 10% adverse change 20% adverse change (Dollars in millions) Option adjusted spread 5.81 % $ 242 $ 238 7.78 % $ 326 $ 318 Constant prepayment rate 9.64 % 238 231 16.68 % 322 311 Weighted average annual cost to service per loan $ 71.00 244 241 $ 68.18 330 326 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 fair value disclosures relating to MSRs, see Note 18 - 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 (loss) return on MSRs 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, net of third party subservicing costs, for loans subserviced.

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. The Company's 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 Income. Derivatives designated as hedging instruments: We have designated certain interest rate swaps as cash flow hedges of certain interest rate payments of our variable-rate FHLB advances. 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 September 30, 2017 , we had $3 million (net-of-tax) of unrealized losses on derivatives designated as cash flow hedges recorded in accumulated other comprehensive income (loss), compared to $1 million of unrealized gains at December 31, 2016 . 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 throughout the hedge period.

We are required to maintain a minimum amount of qualifying collateral. In the event of default, the FHLB advance is similar to a secured borrowing, whereby the FHLB has the right to sell the pledged collateral to settle the fair value of the outstanding advances. At September 30, 2017 , we had the authority and approval from the FHLB to utilize a line of credit of up to $7.0 billion and we may access that line to the extent that collateral is provided. At September 30, 2017 , we had $5.4 billion of advances outstanding and an additional $1.1 billion of collateralized borrowing capacity available at the FHLB. The advances can be collateralized by non-delinquent single-family residential first mortgage loans, loans with government guarantees, certain other loans and investment securities. At September 30, 2017 , $1.0 billion of the outstanding advances were long-term adjustable rate, with interest rates that reset every three months and are based on the three -month LIBOR index. The advances may be prepaid without penalty, with notification at scheduled three month intervals after an initial 12 month lockout period which is based on the settlement date of each advance. The outstanding advances included $830 million in a cash flow hedge relationship as discussed in Note 8 - Derivative Financial Instruments.

The proceeds from these notes were used to bring dividends current and redeem our outstanding TARP Preferred. The notes are unsecured and rank equally and ratably with the unsecured senior indebtedness of Flagstar Bancorp, Inc. Prior to June 15, 2021, we may redeem some or all of the Senior Notes at a redemption price equal to the greater of 100 percent of the aggregate principal amount of the notes to be redeemed or the sum of the present values of the remaining scheduled payments discounted to the redemption date on a semi-annual basis using a discount rate equal to the Treasury Rate plus 0.50 percent , plus, in each case accrued and unpaid interest. Trust Preferred Securities We sponsor nine trust subsidiaries, which issued preferred stock to third party investors. We issued trust preferred securities to those trusts, which we have included in long-term debt. The trust preferred 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 September 30, 2017 , 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 September 30, Nine Months Ended September 30, 2017 2016 2017 2016 (Dollars in millions, except share data) Net income $ 40 $ 57 $ 108 $ 143 Deferred cumulative preferred stock dividends — (2 ) — (18 ) Net income applicable to common stockholders $ 40 $ 55 $ 108 $ 125 Weighted average shares Weighted average common shares outstanding 57,162,025 56,580,238 57,062,696 56,556,188 Effect of dilutive securities May Investor Warrants — 364,791 16,383 339,893 Stock-based awards 1,024,568 988,777 1,054,217 831,181 Weighted average diluted common shares 58,186,593 57,933,806 58,133,296 57,727,262 Earnings per common share Basic earnings per common share $ 0.71 $ 0.98 $ 1.90 $ 2.21 Effect of dilutive securities May Investor Warrants — — — (0.02 ) Stock-based awards (0.01 ) (0.02 ) (0.04 ) (0.03 ) Diluted earnings per common share $ 0.70 $ 0.96 $ 1.86 $ 2.16 Under the terms of the TARP Preferred, the Company elected to defer payments of preferred stock dividends beginning with the February 2012 dividend. Although, while being deferred, the impact was not included in quarterly net income from continuing operations, the deferral did impact net income applicable to common stock for the purpose of calculating earnings per share, as shown above.

Regulatory Capital Requirements [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. On January 1, 2015 , the Basel III rules became effective and include transition provisions through 2018. 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 September 30, 2017 and December 31, 2016 .

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 September 30, 2017 , 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 litigation settlement In 2012, the Bank entered into a Settlement Agreement with the DOJ which meets the definition of a financial liability (the "DOJ Liability"). In accordance with the Settlement Agreement, we made an initial payment of $15 million and agreed to make future annual payments totaling $118 million in annual increments of up to $25 million upon meeting all 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 the third quarter of 2016; and (c) the Bank’s Tier 1 Leverage Capital Ratio equals 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 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. We elected to account for the DOJ Liability under the fair value option. To determine the fair value, we utilize a discounted cash flow model. Key assumptions for the discounted cash flow model include using a discount rate as of September 30, 2017 of 9.4 percent ; probability weightings of multiple cash flow scenarios and possible outcomes which contemplate the above conditions and estimates of forecasted net income, size of the balance sheet, capital levels, dividends and their impact on the timing of cash payments and the assumptions we believe a market participant would make to transfer the liability. The fair value of the DOJ Liability was $60 million at both September 30, 2017 and December 31, 2016 . Other litigation accruals At September 30, 2017 and December 31, 2016 , excluding the fair value liability relating to the DOJ litigation settlement, our total accrual for contingent liabilities, settled litigation and regulatory matters was $2 million and $3 million , respectively. Commitments The following table is a summary of the contractual amount of significant commitments: September 30, 2017 December 31, 2016 (Dollars in millions) Commitments to extend credit Mortgage loans interest-rate lock commitments $ 4,804 $ 4,115 Warehouse loan commitments 1,560 1,670 Commercial and industrial commitments 692 424 Other commercial commitments 955 651 HELOC commitments 241 179 Other consumer commitments 51 57 Standby and commercial letters of credit 46 30 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 interest-rate lock commitments. We enter into mortgage interest-rate lock commitments with our customers. These 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. C onditional commitments issued to accommodate the financial needs of customers. The commitments are 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. 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. A reserve balance of $3 million at both September 30, 2017 and December 31, 2016 is reflected in other liabilities on the Consolidated Statements of Financial Condition.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We utilize fair value measurements to record or disclose the fair value on certain assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability through an orderly transaction between market participants at the measurement date. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation models rely on market-based parameters when available, such as interest rate yield curves or credit spreads. Unobservable inputs may be based on management's judgment, assumptions and estimates related to credit quality, our future earnings, interest rates and other relevant inputs. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. Refer to Note 22 - Fair Value Measurements to the consolidated financial statements of the Annual Report on Form 10-K for the year ended December 31, 2016 for a description of our valuation methodologies and information about the fair value hierarchy. 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. September 30, 2017 Level 1 Level 2 Level 3 Total Fair Value (Dollars in millions) Investment securities available-for-sale Agency - Commercial $ — $ 750 $ — $ 750 Agency - Residential — 809 — 809 Municipal obligations — 44 — 44 Corporate debt obligations — 34 — 34 Loans held-for-sale Residential first mortgage loans — 4,907 — 4,907 Loans held-for-investment Residential first mortgage loans — 9 — 9 Home equity — — 4 4 Mortgage servicing rights — — 246 246 Derivative assets Rate lock commitments (fallout-adjusted) — — 33 33 Mortgage-backed securities forwards — 12 — 12 Interest rate swaps and swaptions — 14 — 14 Interest rate swap on FHLB advances (net) — 1 — 1 Total assets at fair value $ — $ 6,580 $ 283 $ 6,863 Derivative liabilities Rate lock commitments (fallout-adjusted) $ — $ — $ (1 ) $ (1 ) Futures (3 ) — — (3 ) Mortgage backed securities forwards — (4 ) — (4 ) Interest rate swaps — (2 ) — (2 ) DOJ litigation settlement — — (60 ) (60 ) Contingent consideration — — (26 ) (26 ) Total liabilities at fair value $ (3 ) $ (6 ) $ (87 ) $ (96 ) On May 15, 2017, the Company closed on the acquisition of certain assets of Opes Advisors (“Opes”), a California based retail mortgage originator and wealth management service provider. Although the acquired assets of Opes were not significant, the addition of Opes positions us to increase our distributed retail lending channel. Consideration in the acquisition of Opes consisted of upfront cash and contingent cash in the form of an earn-out. The earn-out is based on future target production volumes and profitability of the division which were significant inputs to the preliminary fair value. We deem the initial valuation of the assets and liabilities to be provisional and have left the measurement period open. These fair values may be adjusted in a future period, not to exceed one year after the acquisition date, to reflect new facts and circumstances which existed as of the acquisition date. During the third quarter of 2017, an adjustment was made to the initial fair value of the acquisition earn-out that was the result of facts and circumstances in existence at the acquisition date. December 31, 2016 Level 1 Level 2 Level 3 Total Fair (Dollars in millions) Investment securities available-for-sale Agency - Commercial $ — $ 548 $ — $ 548 Agency - Residential — 898 — 898 Municipal obligations — 34 — 34 Loans held-for-sale Residential first mortgage loans — 3,145 — 3,145 Loans held-for-investment Residential first mortgage loans — 7 — 7 Home equity — — 65 65 Mortgage servicing rights — — 335 335 Derivative assets Rate lock commitments (fallout-adjusted) — — 24 24 Futures 2 — — 2 Mortgage backed securities forwards — 43 — 43 Interest rate swaps and swaptions — 35 — 35 Interest rate swaps on FHLB advances (net) — 19 — 19 Total assets at fair value $ 2 $ 4,729 $ 424 $ 5,155 Derivative liabilities Rate lock commitments (fallout-adjusted) $ — $ — $ (6 ) $ (6 ) Mortgage backed securities forwards — (11 ) — (11 ) Interest rate swaps — (37 ) — (37 ) Warrant liabilities — (4 ) — (4 ) DOJ litigation settlement — — (60 ) (60 ) Total liabilities at fair value $ — $ (52 ) $ (66 ) $ (118 ) There were no transfers between Level 1 and Level 2 during the nine months ended September 30, 2017 . Fair Value Measurements Using Significant Unobservable Inputs The following tables include a roll forward of the Consolidated Statements of Financial Condition amounts (including the change in fair value) for financial instruments classified by us within level 3 of the valuation hierarchy: Recorded in Earnings Recorded in OCI Balance at Beginning of Period Total Unrealized Gains / (Losses) Total Realized Gains / (Losses) Total Unrealized Gains / (Losses) Purchases / Originations Sales Settlements Transfers In (Out) Balance at End of Period (Dollars in millions) Three Months Ended September 30, 2017 Assets Loans held-for-investment Home equity $ 5 $ — $ — $ — $ — $ — $ (1 ) $ — $ 4 Mortgage servicing rights 184 (9 ) — — 75 (4 ) — — 246 Rate lock commitments (net) (1) 26 21 — — 82 — — (97 ) 32 Totals $ 215 $ 12 $ — $ — $ 157 $ (4 ) $ (1 ) $ (97 ) $ 282 Liabilities DOJ litigation settlement $ (60 ) $ — $ — $ — $ — $ — $ — $ — $ (60 ) Contingent consideration (23 ) (1 ) — — (2 ) — — — (26 ) Totals $ (83 ) $ (1 ) $ — $ — $ (2 ) $ — $ — $ — $ (86 ) Three Months Ended September 30, 2016 Assets Loans held-for-investment Home equity $ 82 $ 4 $ — $ — $ — $ — $ (14 ) $ — $ 72 Mortgage servicing rights 301 (33 ) — — 51 (17 ) — — 302 Rate lock commitments (net) (1) 82 33 — — 116 (150 ) (18 ) — 63 Totals $ 465 $ 4 $ — $ — $ 167 $ (167 ) $ (32 ) $ — $ 437 Liabilities DOJ litigation settlement $ (84 ) $ 24 $ — $ — $ — $ — $ — $ — $ (60 ) (1) 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. We utilized swaptions futures, forward agency and loan sales and interest rate swaps to manage the risk associated with MSRs and rate lock commitments. Gains and losses for individual lines in the tables do not reflect the effect of our risk management activities related to such level 3 instruments. 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) September 30, 2017 Assets Loans held-for-investment Home equity $ 4 Discounted cash flows Discount rate 7.2% - 10.8% (9.0%) Mortgage servicing rights $ 246 Discounted cash flows Option adjusted spread 4.7% - 7.0% (5.8%) Rate lock commitments (net) $ 32 Consensus pricing Origination pull-through rate 63.9% - 95.9% (79.9%) Liabilities DOJ litigation settlement $ 60 Discounted cash flows Discount rate 7.5% - 11.3% (9.4%) Contingent consideration $ 26 Discounted cash flows Beta 0.6 - 1.6 (1.1) Fair Value Valuation Technique Unobservable Input Range (Weighted Average) (Dollars in millions) December 31, 2016 Assets Loans held-for-investment Home equity $ 65 Discounted cash flows Discount rate 6.0% - 12.2% (9.3%) Mortgage servicing rights $ 335 Discounted cash flows Option adjusted spread 6.2% - 9.3% (7.8%) Rate lock commitments (net) $ 18 Consensus pricing Origination pull-through rate 66.9% - 100.0% (83.6%) Liabilities DOJ litigation settlement $ 60 Discounted cash flows Discount rate 6.6% - 9.8% (8.2%) Recurring Significant Unobservable Inputs Home equity. The 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 would 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. HELOC loans formerly included in the FSTAR 2005-1 and FSTAR 2006-1 securitization trusts, also classified as home equity loans, were valued utilizing a loan-level discounted cash flow model which projects expected cash flows given three potential outcomes: (1) paid-in-full at scheduled maturity, (2) default at scheduled maturity (foreclosure), and (3) modification at scheduled maturity into an amortizing HELOC. Loans are placed into the potential outcome buckets based on their underlying current delinquency, FICO scores and property CLTV all of which are unobservable inputs. These loans were sold in the second quarter of 2017. 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 would result in a significantly lower (higher) fair value measurement. Weighted average life (in years) is used to determine the change in fair value of MSRs. For September 30, 2017 and December 31, 2016 the weighted average life (in years) for the entire MSRs portfolio was 6.0 and 6.6 , respectively. DOJ litigation settlement. The significant unobservable input used in the fair value measurement of the DOJ litigation settlement is the discount rate and asset growth rate, in addition to those discussed in Note 17 - Legal Proceedings, Contingencies and Commitments. Significant increases (decreases) in the discount rate or asset growth rate in isolation would result in a marginally lower (higher) fair value measurement. For further information on the fair value inputs related to the DOJ litigation, see Note 17 - Legal Proceedings, Contingencies, and Commitments. Rate lock commitments. The significant unobservable input used in the fair value measurement of the rate lock commitments is the pull through rate. The pull through rate is a statistical analysis of our actual rate lock fallout history to determine the sensitivity of the residential mortgage loan pipeline compared to interest rate changes and other deterministic values. New market prices are applied based on updated loan characteristics and new fallout ratios (i.e., the inverse of the pull through rate) are applied accordingly. Significant increases (decreases) in the pull through rate in isolation would 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 profitability of the division. An increase or decrease to these inputs results in an increase or decrease of the liability. Other unobservable inputs include Beta and volatility which drive the risk adjusted discount rate utilized in a Monte Carlo simulation. An increase or decrease in these inputs results in a decrease or increase to the liability. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis We also have assets that under certain conditions are subject to measurement at fair value on a nonrecurring basis. The following table presents assets measured at fair value on a nonrecurring basis: Total (1) Level 2 Level 3 Gains/(Losses) (Dollars in millions) September 30, 2017 Loans held-for-sale (2) $ 6 $ 6 $ — $ (1 ) Impaired loans held-for-investment (2) Loans held-for-investment 23 — 23 (8 ) Repossessed assets (3) 9 — 9 — Totals $ 38 $ 6 $ 32 $ (9 ) December 31, 2016 Loans held-for-sale (2) $ 9 $ 9 $ — $ (2 ) Impaired loans held-for-investment (2) Residential first mortgage loans 25 — 25 (28 ) Repossessed assets (3) 14 — 14 (2 ) Totals $ 48 $ 9 $ 39 $ (32 ) (1) The fair values are determined at various dates during the nine months ended September 30, 2017 and the year ended December 31, 2016 , 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 tables present 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) September 30, 2017 Impaired loans held-for-investment Loans held-for-investment $ 23 Fair value of collateral Loss severity discount 28% - 31% (29.6%) Repossessed assets $ 9 Fair value of collateral Loss severity discount 29% - 100% (75.3%) December 31, 2016 Impaired loans held-for-investment Residential first mortgage loans $ 25 Fair value of collateral Loss severity discount 22% - 40% (29.5%) Repossessed assets $ 14 Fair value of collateral Loss severity discount 22% - 100% (69.5%) 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: September 30, 2017 Estimated Fair Value Carrying Value Total Level 1 Level 2 Level 3 (Dollars in millions) Assets Cash and cash equivalents $ 233 $ 233 $ 233 $ — $ — Investment securities available-for-sale 1,637 1,637 — 1,637 — Investment securities held-to-maturity 977 971 — 971 — Loans held-for-sale 4,939 4,940 — 4,940 — Loans held-for-investment 7,203 7,181 — 9 7,172 Loans with government guarantees 253 245 — 245 — Mortgage servicing rights 246 246 — — 246 Federal Home Loan Bank stock 264 264 — 264 — Bank owned life insurance 328 328 — 328 — Repossessed assets 9 9 — — 9 Other assets, foreclosure claims 92 92 — 92 — Derivative financial instruments, assets 60 60 — 27 33 Liabilities Retail deposits Demand deposits and savings accounts $ (5,243 ) $ (4,845 ) $ — $ (4,845 ) $ — Certificates of deposit (1,297 ) (1,304 ) — (1,304 ) — Wholesale deposits (43 ) (43 ) — (43 ) — Government deposits (1,068 ) (1,045 ) — (1,045 ) — Company controlled deposits (1,510 ) (1,473 ) — (1,473 ) — Federal Home Loan Bank advances (5,365 ) (5,252 ) — (5,252 ) — Long-term debt (493 ) (382 ) — (382 ) — DOJ litigation settlement (60 ) (60 ) — — (60 ) Contingent consideration (26 ) (26 ) — — (26 ) Derivative financial instruments, liabilities (10 ) (10 ) (3 ) (6 ) (1 ) December 31, 2016 Estimated Fair Value Carrying Value Total Level 1 Level 2 Level 3 (Dollars in millions) Assets Cash and cash equivalents $ 158 $ 158 $ 158 $ — $ — Investment securities available-for-sale 1,480 1,480 — 1,480 — Investment securities held-to-maturity 1,093 1,084 — 1,084 — Loans held-for-sale 3,177 3,178 — 3,178 — Loans held-for-investment 6,065 5,998 — 7 5,991 Loans with government guarantees 365 354 — 354 — Mortgage servicing rights 335 335 — — 335 Federal Home Loan Bank stock 180 180 — 180 — Bank owned life insurance 271 271 — 271 — Repossessed assets 14 14 — — 14 Other assets, foreclosure claims 135 135 — 135 — Derivative financial instruments, assets 123 123 45 54 24 Liabilities Retail deposits Demand deposits and savings accounts $ (5,268 ) $ (4,956 ) $ — $ (4,956 ) $ — Certificates of deposit (1,056 ) (1,062 ) — (1,062 ) — Government deposits (1,030 ) (1,011 ) — (1,011 ) — Company controlled deposits (1,446 ) (1,371 ) — (1,371 ) — Federal Home Loan Bank advances (2,980 ) (2,964 ) — (2,964 ) — Long-term debt (493 ) (277 ) — (277 ) — Warrant liabilities (4 ) (4 ) — (4 ) — DOJ litigation settlement (60 ) (60 ) — — (60 ) Derivative financial instruments, liabilities (54 ) (54 ) (11 ) (37 ) (6 ) The methods and assumptions used by us in estimating fair value of financial instruments which are required for disclosure only, are as follows: Cash and cash equivalents. Due to their short-term nature, the carrying amount of cash and cash equivalents approximates fair value. Investment securities held-to-maturity. Fair values are generated using market inputs, where possible, including quoted prices (the closing price in an exchange market), bid prices (the price at which a buyer stands ready to purchase), and other market information. Loans held-for-investment. The fair value is estimated using internally developed discounted cash flow models using market interest rate inputs as well as management’s best estimate of spreads for similar collateral. Loans with government guarantees. The fair value is estimated by using internally developed discounted cash flow models using market interest rate inputs as well as management’s best estimate of spreads for similar collateral. Federal Home Loan Bank stock. No secondary market exists for FHLB stock. The stock is bought and sold at par by the FHLB. Management believes that the recorded value equals the fair value. Bank owned life insurance. The fair value of bank owned life insurance policies is based on the cash surrender values of the policies as reported by the insurance companies. Other assets, foreclosure claims. The fair value of foreclosure claims with government guarantees approximates the carrying amount. Deposit accounts. The fair value of deposits with no defined maturity is estimated based on a discounted cash flow model that incorporates current market rates for similar products and expected attrition. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for certificates of deposit with similar remaining maturities. Federal Home Loan Bank advances. Rates currently available for debt with similar terms and remaining maturities are used to estimate the fair value of the existing debt. Long-term debt. The fair value of the long-term debt is estimated based on a discounted cash flow model that incorporates current borrowing rates for similar types of borrowing arrangements. Fair Value Option We elected the fair value option for certain items as discussed throughout the Notes to the Consolidated Financial Statements to mitigate a divergence between accounting losses and 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 September 30, Nine Months Ended September 30, 2017 2016 2017 2016 (Dollars in millions) Assets Loans held-for-sale Net gain on loan sales $ 92 $ 151 $ 260 $ 440 Loans held-for-investment Other noninterest income $ — $ — $ 1 $ (2 ) Liabilities Other noninterest income $ — $ 24 $ — $ 24 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: September 30, 2017 December 31, 2016 Unpaid Principal Balance Fair Value Fair Value Over / (Under) Unpaid Principal Balance Unpaid Principal Balance Fair Value Fair Value Over / (Under) Unpaid Principal Balance (Dollars in millions) Assets Nonaccrual loans Loans held-for-sale $ 4 $ 4 $ — $ 2 $ 2 $ — Loans held-for-investment 6 4 (2 ) 19 13 (6 ) Total nonaccrual loans $ 10 $ 8 $ (2 ) $ 21 $ 15 $ (6 ) Other performing loans Loans held-for-sale $ 4,742 $ 4,903 $ 161 $ 3,103 $ 3,143 $ 40 Loans held-for-investment 11 9 (2 ) 72 59 (13 ) Total other performing loans $ 4,753 $ 4,912 $ 159 $ 3,175 $ 3,202 $ 27 Total loans Loans held-for-sale $ 4,746 $ 4,907 $ 161 $ 3,105 $ 3,145 $ 40 Loans held-for-investment 17 13 (4 ) 91 72 (19 ) Total loans $ 4,763 $ 4,920 $ 157 $ 3,196 $ 3,217 $ 21 Liabilities Litigation settlement (1) $ (118 ) $ (60 ) $ 58 $ (118 ) $ (60 ) $ 58 (1) We are obligated to pay $118 million in installment payments upon meeting certain performance conditions, as described in Note 17 - Legal Proceedings, Contingencies and Commitments.

Segment Information

Segment Reporting [Abstract]
Segment Information	Segment Information Our operations are conducted through three operating segments: Community Banking, Mortgage Originations, and Mortgage Servicing. The Other segment includes the remaining reported activities. Operating segments are defined as components of an enterprise that engage in business activity from which revenues are earned and expenses 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. Effective January 1, 2017, activity related to Loans with Government Guarantees, was moved from the Mortgage Servicing segment to the Mortgage Originations segment and we began to allocate the tax provision at a segment level. Prior to this change, the tax provision was reflected in the Other segment. The statutory federal tax rate is used for Community Banking, Mortgage Originations, and Mortgage Servicing segments with the difference between the statutory rate and the effective tax rate held in the Other segment. Prior period segment financial information, related to both changes, 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. In addition, wealth management products and services are provided through Opes as of the acquisition date of May 15, 2017. The Mortgage Originations segment originates, acquires and sells one-to-four family residential mortgage loans. The origination and acquisition of mortgage loans comprises the majority of the lending activity. Mortgage loans are originated through home loan centers, national call centers, the Internet and unaffiliated banks and mortgage banking and brokerage companies, where the net interest income and the gains from sales associated with these loans are recognized in the Mortgage Originations segment. The Mortgage Servicing segment services and subservices mortgage 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 provides servicing of residential mortgages for our own LHFI portfolio in the Community Banking segment for which it earns revenue via an intercompany service fee allocation. The Other segment includes the treasury functions, funding revenue associated with stockholders' equity, the impact of interest rate risk management, the impact of balance sheet funding activities, and miscellaneous other expenses of a corporate nature. Treasury functions include administering the investment securities portfolios, balance sheet funding, and interest rate risk management. 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 Mortgage Originations, Mortgage Servicing or Community Banking operating segments. Revenues are comprised of net interest income (before the provision (benefit) for loan 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.

Accounting Policies [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Adoption of New Accounting Standards We adopted the following accounting standard updates (ASU) during 2017 , none of which had a material impact to our financial statements: Standard Description Effective Date ASU 2016-17 Consolidation (Topic 810): Interests Held Through Related Parties That are Under Common Control January 1, 2017 ASU 2016-09 Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting January 1, 2017 ASU 2016-07 Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting January 1, 2017 ASU 2016-06 Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments January 1, 2017 ASU 2016-05 Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Relationships January 1, 2017 Accounting Standards Issued But Not Yet Adopted The following ASUs have been issued and are expected to result in a significant change to our significant accounting policies and/or have a significant financial impact: Derivatives and Hedging - In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments were designed to more closely align hedge accounting requirements with users’ risk management strategies. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. We do not expect adoption of this guidance to have a material impact on our Consolidated Financial Statements. However, the guidance is expected to provide a broader range of hedge accounting opportunities and simplify the internal documentation requirements for our existing cash flow hedge relationships. Credit Losses - In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326). The ASU alters the current method for recognizing credit losses within the reserve account. Currently, an institution uses the incurred loss method, whereas 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 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. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019. We have established an internal steering committee to lead the implementation efforts. The steering committee is in the process of evaluating control and process framework, data, model, and resource requirements and areas where modifications will be required. We are currently evaluating the impact adoption of the guidance will have on our Consolidated Financial Statements, and highlight that any impact will be contingent upon the underlying characteristics of the affected portfolio and macroeconomic and internal forecasts at adoption date. Leases - In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842): Section A - Leases: Amendments to the FASB Accounting Standards Codification, Section B - Conforming Amendments Related to Leases: Amendment to the FASB Accounting Standards Codification, Section C - Background Information and Basis For Conclusions. Lessees will need to recognize substantially all leases on their balance sheet as a right-of-use asset and a lease liability. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting. ASU 2016-02 is effective retrospectively for fiscal years beginning after December 15, 2018 and early adoption is permitted. The guidance in ASU 2016-02 supersedes Topic 840, Leases. Upon adoption and implementation, we expect to gross up assets and liabilities due to the recognition of lease liabilities and right of use assets associated with the underlying lease contracts. While we do not expect the adoption of the guidance to have a material impact on our Consolidated Statements of Operations given our current inventory of leases, review is ongoing and we will continue to evaluate the impact to the Consolidated Statements of Financial Condition and to capital. Revenue from Contracts with Customers - In May 2014, FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." Under the amended guidance, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration in exchange for those goods or services. The FASB has voted to approve a year deferral of the effective date from January 1, 2017 to January 1, 2018. In April 2016, the FASB clarified the following two aspects: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. In May 2016, the FASB issued ASU 2016-12 Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, to provide a limited number of changes to its revenue recognition standard. The amendments clarify the assessment of the likelihood that revenue will be collected from a contract, the guidance for presenting sales taxes and similar taxes, and the timing for measuring customer payments that are not in cash. The amendment also specifies that a contract should be considered complete if all, or substantially all, of its revenue has been collected prior to making the transition to the new standard. In addition, the update clarifies the disclosure requirements for transition to the new standard by adjusting amounts from prior reporting periods. In December 2016, the FASB issued ASU 2016-20 Technical Corrections and Improvement to Topic 606, Revenue from Contracts with Customers. We will implement the revenue recognition guidance in the first quarter of 2018 utilizing the cumulative-effect approach. Our implementation of the guidance includes creating an inventory of revenue contracts and assessing whether the recognition of revenue associated with each contract will be impacted by the new guidance, particularly related to certain fees. Lease contracts and financial instruments, which include loans and securities, are excluded from the scope of this standard. Therefore, we do not anticipate the implementation of the revenue recognition guidance to have a material impact on our Consolidated Financial Statements. The initial scoping has been completed and the amount of in scope revenue is less than 3% of total revenue. Additionally, the recognition of revenue for in scope items is not anticipated to materially change such that we do not expect implementation of the revenue recognition guidance to have a material impact on our Consolidated Financial Statements or associated disclosures. 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 ASU 2017-11 Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Non-controlling Interests with a Scope. January 1, 2019 ASU 2017-10 Service Concession Arrangements (Topic 853): Determining the Customer of the Operation Services (a consensus of the FASB Emerging Issues Task Force) January 1, 2018 ASU 2017-09 Update 2017-09—Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting January 1, 2018 ASU 2017-08 Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities January 1, 2019 ASU 2017-07 Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost January 1, 2018 ASU 2017-06 Plan Accounting - Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965): Employee Benefit Plan Master Trust Reporting January 1, 2019 ASU 2017-05 Other Income - Gains and Losses from the De-recognition of Non-financial Assets (Subtopic 610-20): Clarifying the Scope of Asset De-recognition Guidance and Accounting for Partial Sales of Non-financial Assets January 1, 2018 ASU 2017-04 Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment January 1, 2020 ASU 2017-01 Business Combinations (Topic 805): Clarifying the Definition of a Business January 1, 2018 ASU 2016-18 Statement of Cash Flows (Topic 230): Restricted Cash January 1, 2018 ASU 2016-16 Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory January 1, 2018 ASU 2016-15 Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments January 1, 2018 ASU 2016-04 Liabilities - Extinguishment of Liabilities (Subtopic 504-20): Recognition of Breakage for Certain Prepaid Stored-Value Products January 1, 2018 ASU 2016-01 Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities January 1, 2018

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. Nonperforming loans are classified as either substandard, doubtful or loss. 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. Because of high probability of loss, non-accrual accounting treatment is required for doubtful assets. 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 this basically worthless asset even though partial recovery may be affected in the future.
Derivative Financial Instruments	Derivative financial instruments are recorded at fair value in other assets and other liabilities on the Consolidated Statements of Financial Condition. The Company's 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 Income. Derivatives designated as hedging instruments: We have designated certain interest rate swaps as cash flow hedges of certain interest rate payments of our variable-rate FHLB advances. 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 September 30, 2017 , we had $3 million (net-of-tax) of unrealized losses on derivatives designated as cash flow hedges recorded in accumulated other comprehensive income (loss), compared to $1 million of unrealized gains at December 31, 2016 . 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 throughout the hedge period. All hedge relationships were and are expected to be highly effective as of September 30, 2017 . Cash flows and the profit impact associated with designated hedges are reported in the same line item as the underlying hedged item.
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. Refer to Note 22 - Fair Value Measurements to the consolidated financial statements of the Annual Report on Form 10-K for the year ended December 31, 2016 for a description of our valuation methodologies and information about the fair value hierarchy.

Although the acquired assets of Opes were not significant, the addition of Opes positions us to increase our distributed retail lending channel. Consideration in the acquisition of Opes consisted of upfront cash and contingent cash in the form of an earn-out. The earn-out is based on future target production volumes and profitability of the division which were significant inputs to the preliminary fair value. We deem the initial valuation of the assets and liabilities to be provisional and have left the measurement period open. These fair values may be adjusted in a future period, not to exceed one year after the acquisition date, to reflect new facts and circumstances which existed as of the acquisition date. During the third quarter of 2017, an adjustment was made to the initial fair value of the acquisition earn-out that was the result of facts and circumstances in existence at the acquisition date.
