Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies	Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies Description of Business Flagstar Bancorp, Inc., is a Michigan-based savings and loan holding company founded in 1993. The Company's business is primarily conducted through its principal subsidiary, Flagstar Bank, FSB (the "Bank"), a Michigan-based federally chartered stock savings bank founded in 1987. We are one of the largest banks headquartered in Michigan. When we refer to "Flagstar", "the Company", "we", "our", or "us," we mean Flagstar Bancorp, Inc. and our consolidated subsidiaries. The Company is subject to regulation, examination and supervision by the Board of Governors of the Federal Reserve ("Federal Reserve"). The Bank is subject to regulation, examination and supervision by the OCC of the U.S. Department of the Treasury, the CFPB and the FDIC. The Bank is a member of the FHLB of Indianapolis and its deposits are insured by the FDIC through the Deposit Insurance Fund. Consolidation and Basis of Presentation The accounting and financial reporting policies of us and our subsidiaries conform to accounting principles generally accepted in the United States. Additionally, where applicable the policies conform to the accounting and reporting guidelines prescribed by regulatory authorities. Certain prior period amounts have been reclassified to conform to the current period presentation. The preparation of the Consolidated Financial Statements, requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, revenues and expenses and disclosures of contingent assets and liabilities. Actual results could be materially different from these estimates. Subsequent Events We have evaluated all subsequent events for potential recognition and disclosure through the filing date of this Form 10-K. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from correspondent banks and the FRB, and Short-term investments that have a maturity at the date of acquisition of three months or less and are readily convertible to cash. Investment Securities We measure securities classified as AFS at fair value, with unrealized gains and losses, net of tax, included in "other comprehensive income (loss)" in stockholders’ equity. We recognize realized gains and losses on AFS securities when securities are sold. The cost of securities sold is based on the specific identification method. Any gains or losses realized upon the sale of a security are reported in "other noninterest income" in the Consolidated Statements of Operations. The fair value of investment securities is based on observable market prices, when available. If observable market prices are not available, our valuations are based on alternative methods, including: quotes for similar fixed-income securities, matrix pricing, discounted cash flow using benchmark interest rate curves or other factors. The fair values, obtained through an independent third party utilizing a pricing service, are compared to independent pricing sources on a quarterly basis. For further information, see Note 2 - Investment Securities and Note 22 - Fair Value Measurements. Investment securities HTM are carried at amortized cost and adjusted for amortization of premiums and accretion of discounts using the interest method. Transfers of investment securities into the HTM category from the AFS category are accounted for at fair value at the date of transfer. Any related unrealized holding gain (loss), net of tax, that was included in the transfer is retained in other comprehensive income (loss) and is amortized as an adjustment to interest income over the remaining life of the securities. We 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) does 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). For the years ended December 31, 2014 through December 31, 2016, we did not recognize any OTTI losses. Investment securities transactions are recorded on the trade date for purchases and sales. Interest earned on investment securities, including the amortization of premiums and the accretion of discounts are determined using the effective interest method over the period of maturity, recorded in interest income in the Consolidated Statements of Operations. For further information, see Note 2 - Investment Securities. Loans Held-for-Sale We classify loans as HFS when we originate or purchase loans that we intend to sell. We have elected the fair value option for the majority of our LHFS. We estimate the fair value of mortgage loans based on quoted market prices for securities backed by similar types of loans, where available, or by discounting estimated cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. LHFS that are recorded at lower of cost or fair value may be carried at fair value on a nonrecurring basis when the fair value is less than cost. For further information, see Note 22 - Fair Value Measurements. Loans that are transferred into the HFS portfolio from the HFI portfolio, due to a change in intent, are recorded at the lower of cost or fair value. Gains or losses recognized upon the sale of loans are determined using the specific identification method. Loans Held-for-Investment We classify loans that we have the intent and ability to hold for the foreseeable future or until maturity as HFI. Loans held-for-investment are reported at their amortized cost, which includes the outstanding principal balance adjusted for any unamortized premiums, discounts, deferred fees and costs. Premiums and discounts on purchased loans and non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, are deferred and recognized over the estimated lives of the related loans as an adjustment to the loans’ effective yield, which is included in interest income on loans in the Consolidated Statements of Operations. Loans originally classified as HFS, for which we have elected the fair value option, and subsequently transferred to HFI continue to be measured and reported at fair value on a recurring basis. Changes in fair value are recorded to "other noninterest income" on the Consolidated Statements of Operations. The fair value of these loans is determined using the same methods described above for LHFS. For additional information relating to recurring fair value disclosures, see Note 22 - Fair Value Measurements. When loans originally classified as HFS or as HFI are reclassified due to a change in intent or ability to hold, cash flows associated with the loans will be classified in the Consolidated Statements of Cash Flows as operating or investing, as appropriate, in accordance with the initial classification of the loans. Past Due and Impaired Loans Loans are considered to be past due when any payment of principal or interest is 30 days past the scheduled payment date. While it is the goal of management to collect on loans, we attempt to work out a satisfactory repayment schedule or modification with past due borrowers and will undertake foreclosure proceedings if the delinquency is not satisfactorily resolved. Our practices regarding past due loans are designed to both assist borrowers in meeting their contractual obligations and minimize losses incurred by the bank. We cease the accrual of interest on all classes of consumer and commercial loans once they become 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 may only return to accrual status when principal and interest become current and are anticipated to be fully collectible. Loans are considered impaired if it is probable that payment of interest and principal will not be made in accordance with the original contractual terms of the loan agreement or when any portion of principal or interest is 90 days past due. This classification includes both performing and nonperforming modified loans. For further information, see Note 22 - Fair Value Measurements. When a loan is considered impaired, the accrual of interest income is discontinued until the receipt of principal and interest is no longer in doubt. Interest income is recognized on impaired loans using a cost recovery method unless amounts contractually due are not in doubt. Cash received on impaired loans are applied entirely against principal until the loan has been collected in full, after which time any additional cash receipts are recognized as interest income. Loan Modifications (Troubled Debt Restructurings) We may modify certain loans in both our consumer and commercial loan portfolios to retain customers or to maximize collection of the outstanding loan balance. We have programs designed to assist borrowers by extending payment dates or reducing the borrower's contractual payments. All loan modifications are made on a case-by-case basis. Our standards relating to loan modifications consider, among other factors, minimum verified income requirements, cash flow analysis, and collateral valuations. TDRs result in those instances in which a borrower demonstrates financial difficulty and for which a concession has been granted, 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. Allowance for Loan Losses The allowance for loan losses represents management's estimate of probable losses in our LHFI portfolio, excluding loans carried under the fair value option. We establish an allowance when (a) available information indicates that it is probable that a loss has occurred and (b) the amount of the loss can be reasonably estimated. The allowance provides for probable losses that have been identified with specific customer relationships (individually evaluated) and for probable losses believed to be inherent in the loan portfolio but that have not been specifically identified (collectively evaluated). Management assigns qualitative factors to each loan portfolio segment based on consideration of the following factors: changes in lending policies and procedures, changes in economic and business conditions, changes in the nature and volume of the portfolio, changes in lending management, changes in credit quality statistics, changes in the quality of the loan review system, changes in the value of underlying collateral for collateral-dependent loans, changes in concentrations of credit, 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 disposal costs if the loan is collateral dependent. A general allowance is established for losses inherent on non-impaired loans by segmenting the portfolio based upon common risk characteristics. The general loss is then determined by using a historical loss model which utilizes our loss history by specific product, or if the product is not sufficiently seasoned, per readily available industry peer loss data. The loss model utilizes a loss emergence period that represents the average amount of time between when the loss event first occurs and when the specific loan is charged-off. In addition to the loss history or peer data, we also include a qualitative adjustment that considers economic risks, industry and geographic concentrations and other factors not adequately captured in our methodology. Consumer loans secured by real estate are charged-off to the estimated fair value of the collateral when a loss is confirmed or at 180 days past due, whichever is sooner. Loss confirming events include, but are not limited to, bankruptcy (unsecured), continued delinquency, foreclosure or receipt of an asset valuation indicating a collateral deficiency and the asset is the sole source of repayment. For consumer loans not secured by real estate, the charge-off is taken upon confirmation or 120 days past due. Commercial loans are evaluated on a loan level basis and either charged-off or written down to net realizable value if a loss confirming event has occurred. Loss confirming events include, but are not limited to, bankruptcy (unsecured), continued delinquency, foreclosure, or receipt of an asset valuation indicating a collateral deficiency and that asset is the sole source of repayment. Transfers of Financial Assets Our recognition of gain or loss on the sale of loans for which we surrender control is accounted for as a sale to the extent that 1) the transferred assets are legally isolated from the us or our consolidated affiliates, even in bankruptcy or other receivership, 2) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company, and 3) we do not maintain the obligation or unilateral ability to reclaim or repurchase the assets. If the sale criteria are met, the transferred financial assets are removed from the Consolidated Statements of Financial Condition and a gain or loss on sale is recognized. Variable Interest Entities An entity that has a controlling financial interest in a variable interest entity ("VIE") is referred to as the primary beneficiary and consolidates the VIE. The Corporation is deemed to have a controlling financial interest and is the primary beneficiary of a VIE if it has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. For further information, see Note 7 - Variable Interest Entities. Repossessed Assets Repossessed assets include one-to-four family residential property, commercial property and one-to-four family homes under construction that were acquired through foreclosure or acceptance of a deed-in-lieu of foreclosure. Repossessed assets are initially recorded in other assets at the estimated fair value of the collateral less estimated costs to sell. Losses arising from the initial acquisition of such properties are charged against the ALLL at the time of transfer. Subsequent declines in value, as well as gains and losses on disposal of these properties, are charged to "asset resolution" within noninterest expense in the Consolidated Statements of Operations as incurred. For Further information, see Note 22 - Fair Value Measurements. Loans with Government Guarantees We originate government guaranteed loans which are pooled and sold as Ginnie Mae MBS. Pursuant to Ginnie Mae servicing guidelines, we have the unilateral right to repurchase loans 90 days or more past due securitized in Ginnie Mae pools. As a result, once the delinquency criteria have been met, and regardless of whether the repurchase option has been exercised, we account for the loans as if they had been repurchased. We recognize the loans and corresponding liability as loans with government guarantees and other liabilities, respectively, in the Consolidated Statements of Financial Condition. If the loan is repurchased, the liability is cash settled and the loan with government guarantee remains. Once repurchased, we may collect losses through a claims process with the government agency, as an approved lender. Federal Home Loan Bank Stock We own stock in the FHLB of Indianapolis as required to permit us to obtain membership in and to borrow from the FHLB. No market quotes exist for the stock. The stock is redeemable at par and is carried at cost. Premises and Equipment Premises and equipment are carried at cost less accumulated depreciation. Land is carried at historical cost. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets which generally ranges from three to thirty years. Capitalized software is amortized on a straight-line basis over its useful life, which generally ranges from three to seven years. Software expenditures, repair and maintenance costs that are considered general, administrative, or of a maintenance nature are expensed as incurred. Mortgage Servicing Rights We purchase and originate mortgage loans for sale to the secondary market and sell the loans on either a servicing-retained or servicing-released basis. If we retain the right to service the loan, an MSR is created at the time of sale which is recorded at fair value. We use an internal valuation model that utilizes an option-adjusted spread and other assumptions to determine the fair value of MSRs. The key assumptions used in the valuation of MSRs include mortgage prepayment speeds and discount rates. Management obtains third-party valuations of the MSR portfolio on a quarterly basis from independent valuation services to assess the reasonableness of the fair value calculated by our internal valuation model. Changes in fair value of our MSRs are reported on the Consolidated Statements of Operations in "net return on mortgage servicing." For Further information, see Note 22 - Fair Value Measurements. We periodically enter into agreements to sell certain of our MSRs, which qualify as sales transactions. A transfer of servicing rights related to loans previously sold qualifies as a sale at the date on which title passes, if substantially all risks and rewards of ownership have irrevocably passed to the transferee and any protection provisions retained by the transferor are minor and can be reasonably estimated. In addition, if a sale is recognized and only minor protection provisions exist, a liability is accrued for the estimated obligation associated with those provisions. Servicing Fee Income Servicing fee income, late fees and ancillary fees received on loans for which we own the MSR, are included in the net return on MSR line of the Consolidated Statements of Operations. The fees are based on a contractual percentage of the outstanding principal and are recorded as income when earned. Subservicing fees, which are included in loan administration income on the Consolidated Statements of Operations are based on a contractual monthly amount per loan including late fees and other ancillary income. Derivatives We utilize derivative instruments to manage the fair value changes in our MSR asset, interest rate lock commitments and loans held for sale portfolio which are exposed to price and interest rate risk, facilitate asset/liability management, minimize the variability of future cash flows on long-term debt, and to meet the needs of our customers. All derivatives are recognized on the Consolidated Statements of Financial Condition as other assets and liabilities, as applicable, at their estimated fair value. For those derivatives designated as qualified cash flow hedges, changes in the fair value of the derivatives, to the extent effective as a hedge, are recorded in accumulated other comprehensive income, net of income taxes, and reclassified into earnings concurrently with the earnings of the hedged item. For derivative instruments designated as qualified fair value hedges, which are used to hedge the exposure of fair value changes of an asset or liability attributable to a particular risk, the gain or loss on the derivative instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in current earnings during the period of the change in fair values. For all other derivatives, changes in the fair value of the derivative are recognized immediately in earnings. A majority of these derivatives are subject to master netting agreements and cleared through a Central Counterparty Clearing House, which mitigates non-performance risk with counterparties and enables us to settle activity on a net basis. We use interest rate swaps, swaptions, futures, and forward loan sale commitments to mitigate the impact of fluctuations in interest rates and interest rate volatility on the fair value of the MSRs. These derivatives are not designated as qualifying hedges. Accordingly, changes in their fair value are reflected in current period earnings under the "net return on MSRs." Interest rate swaps, swaptions, futures, and forward loan sale commitments are valued based on quoted prices for similar assets in an active market with inputs that are observable. We also enter into various derivative agreements with customers and correspondents in the form of interest-rate lock commitments and forward purchase contracts which are commitments to originate or purchase mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The derivatives are valued using internal models that utilize market interest rates and other unobservable inputs. Changes in the fair value of these commitments due to fluctuations in interest rates that are to be originated to our HFS portfolio are economically hedged through the use of forward loan sale commitments of MBS. The gains and losses arising from this derivative activity are reflected in current period earnings under the "net gain on loan sales." Interest rate lock commitments are valued using internal models with significant unobservable market parameters. Forward loan sale commitments are valued based on quoted prices for similar assets in an active market with inputs that are observable. At certain times we may also enter into various derivative agreements with correspondents in the form of forward purchase contracts at the time the correspondent customer enters into an interest-rate lock commitment. The derivatives are valued using internal models that utilize market interest rates and other unobservable inputs. We utilize interest rate swaps to hedge the forecasted cash flows from our underlying variable-rate FHLB advances and forecasted FHLB advances in qualifying cash flow hedge accounting relationships. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense concurrently with the interest expense on the debt. Interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable. These hedges are evaluated for effectiveness using regression analysis at the time they are designated and throughout the hedge period. For forecasted FHLB advances being hedged, each reporting period we evaluate the likelihood of the transaction occurring based on the current facts and circumstances to ensure the hedge relationship still qualifies for hedge accounting. If we de-designate a hedge relationship or determine that an interest rate swap no longer qualifies for hedge accounting changes in fair value are no longer recorded in other comprehensive income. If the hedged item remains probable to occur, the effective amounts previously recorded in other comprehensive income are recognized in earnings over the remaining life of the hedged item as an adjustment to yield. We also utilize interest rate swaps to manage fair value changes of our fixed-rate FHLB advances in a qualifying fair value hedge accounting relationship. Changes in the fair value of derivatives designated as fair value hedges, as well as the change in fair value of the hedged item, are recognized in current period earnings. The corresponding adjustment is recorded as a basis adjustment to the hedged item and hedging instrument. Interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable. These hedges are evaluated for effectiveness using regression analysis at the time they are designated and throughout the hedge period. If the Company determines an interest rate swap no longer qualifies for fair value hedge accounting or is de-designated, the hedged item will no longer be adjusted for changes in fair value and the amounts previously recorded as a basis adjustment are recognized in earnings over the remaining life of the hedged item as an adjustment to yield. If a previously hedged item is extinguished or sold, the remaining unamortized balance in other comprehensive income balance for prior cash flow hedges and the remaining basis adjustment of the hedged item for prior fair value hedges will be reclassified to current period earnings. To assist our customers in meeting their needs to manage interest rate risk, we enter into interest rate swap derivative contracts. To economically hedge this risk, we enter into offsetting derivative contracts to effectively eliminate the interest rate risk associated with these contracts. For further information regarding the accounting for derivatives see, Note 11 - Derivative Financial Instruments and additional recurring fair value disclosures in Note 22 - Fair Value Measurements. Bank Owned Life Insurance Our bank owned life insurance policies are recorded at their cash surrender value in Other assets on the Consolidated Statements of Financial Condition. We recognize tax-exempt income from the periodic increases in the cash surrender value of these policies and from death benefits in other noninterest income on the Consolidated Statements of Operations. The total cash surrender value of our bank owned life insurance policies totaled $271 million and $178 million at December 31, 2016 and 2015 , respectively. Income Taxes We evaluate two components of income tax expense: current and deferred. Current income tax expense represents our estimated taxes to be paid or refunded for the current period. Deferred taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates that will apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date. We evaluate our deferred tax assets to determine if, based on all available evidence, it is more likely than not that they will be realized. If it is determined that it is more likely than not that the deferred taxes will not be realized, we establish a valuation allowance. For further information, see Note 19 - Income Taxes. Representation and Warranty Reserve When we sell mortgage loans into the secondary mortgage market, we make customary representations and warranties to the purchasers about various characteristics of each loan, such as the manner of origination, the nature and extent of underwriting standards applied and the types of documentation being provided. For eligible loans sold to the Agencies after December 31, 2014, certain of these representations and warranties expire after 36 months. Typically, all other representations and warranties are in place for the life of the loan. If a defect in the origination process is identified, we may be required to either repurchase the loan, pay a fee or indemnify the purchaser for losses it sustains on the loan. If there are no such defects, the Company has no liability to the purchaser for losses it may incur on such loan. Upon the sale of a loan, the Company recognizes a liability for that guarantee at its fair value as a reduction of our net gain on loan sales. Subsequent to the sale, the liability is re-measured on an ongoing basis based on an estimate of probable future losses. In each case, these estimates are based on our most recent data including loss severity on repurchased and indemnified loans, repurchase requests and other factors. Changes to our previous estimates are recorded in the representation and warranty (provision) benefit in the Consolidated Statements of Operations. Advertising Costs Advertising costs are expensed in the period they are incurred and are included as part of other noninterest expense in the Consolidated Statements of Operations. Advertising expenses totaled $11 million , $9 million , and $10 million for the years ended December 31, 2016 , 2015 and 2014 , respectively. Stock-Based Compensation All share-based payments to employees, including grants of employee stock options and restricted stock units, are classified as equity with expenses being recognized in compensation and benefits in the Consolidated Statements of Operations based on their fair values. The amount of compensation is measured at the grant date and is expensed over the requisite service period, which is normally the vesting period. For further information, see Note 18 - Stock-Based Compensation. Department of Justice Litigation Settlement The executed settlement agreement with the DOJ representing the obligation to make future additional payments establishes a legally enforceable contract with a stipulated payment plan that meets the definition of a financial liability. We have elected the fair value option to account for this financial liability included in "other liabilities" on the Consolidated Financial Statements. For further information on the valuation of the DOJ litigation settlement, see Note 22 - Fair Value Measurements. Recently Issued Accounting Pronouncements Business Combinations - In January 2017, the FASB issued ASU 2017-1, Business Combinations (Topic 805): Clarifying the Definition of a Business. Under the current implementation guidance in Topic 805, there are three elements of a business—inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a "set") that is a business usually has outputs, outputs are not required to be present. This amendment provides a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. ASU 2017-1 is effective for fiscal years beginning after December 15, 2017. We are currently evaluating this guidance. Statement of Cash Flows - Restricted Cash - In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted c

Management evaluates our securities portfolio each quarter to determine if any security is considered to be other than temporarily impaired. In making this evaluation, management considers our ability and intent to hold securities to recover current market losses. During the years ended December 31, 2016 , 2015 and 2014 , we had no OTTI. 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, reported as a component of other comprehensive income. We purchased $680 million of AFS securities, which included U.S. government sponsored agency MBS and municipal obligations during the year ended December 31, 2016 . During the year ended December 31, 2015 , we purchased $1.1 billion of investment securities, all of which were U.S. government sponsored agencies, comprised of MBS and collateralized mortgage obligations and $14 million of municipal obligations, compared to $1.2 billion of investment securities, all of which were U.S. government sponsored agencies, comprised of MBS and collateralized mortgage obligations during the year ended December 31, 2014 . Gains (losses) on the sales of AFS securities are reported in other noninterest income in the Consolidated Statements of Operations. During the year ended December 31, 2016 , there were $291 million in sales of U.S. government sponsored agency securities, which resulted in a gain of $4 million . During the year ended December 31, 2015 , we sold $170 million of U.S. government sponsored agency securities, which resulted in a gain of $3 million , compared to $414 million of U.S. government sponsored agencies, which resulted in a gain of $4 million during the year ended December 31, 2014 . Held-to-maturity securities Transfers of investment securities into the HTM category from the AFS category are accounted for at fair value at the date of transfer. During the year ended December 31, 2015 , we transferred $1.1 billion of AFS securities to HTM securities including a premium of $8 million , reflecting our intent and ability to hold those securities to maturity. The related $5 million of unrealized holding gain, net of tax, that was included in the transfer is retained in other comprehensive income (loss) and is being amortized as an adjustment to interest income over the remaining life of the securities. There were no gains or losses recognized as a result of this transfer. We purchased $15 million of HTM securities, which included U.S. government sponsored agency MBS during the year ended December 31, 2016 . We purchased $217 million of HTM securities, which included agency-collateralized mortgage obligations during the year ended December 31, 2015 . There were no purchases of HTM securities during the year ended December 31, 2014 . We had no sales of HTM securities during the years ending December 31, 2016 , 2015 and 2014 , respectively.

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 and 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 exposes 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 December 31, 2016 and December 31, 2015 , respectively, loans with government guarantees totaled $365 million and $485 million . At December 31, 2016 , repossessed assets and the associated claims recorded in other assets totaled $135 million and at December 31, 2015 repossessed assets and the associated claims were $210 million .

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 liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. For HELOC 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 as 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 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 of the deal, 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 result 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, 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.

Mortgage Servicing Rights

Mortgage Servicing Rights	12 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. 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, see Note 11 - Derivative Financial Instruments, regarding the derivative instruments utilized to manage our MSR risks. Changes in the carrying value of residential first mortgage MSRs, accounted for at fair value, were as follows: For the Years Ended December 31, 2016 2015 2014 (Dollars in millions) Balance at beginning of period $ 296 $ 258 $ 285 Additions from loans sold with servicing retained 228 260 272 Reductions from sales (84 ) (176 ) (232 ) Changes in fair value due to (1) Decrease in MSR value due to pay-offs, pay-downs, and runoff (62 ) (43 ) (31 ) Changes in estimates of fair value (2) (43 ) (3 ) (36 ) Fair value of MSRs at end of period $ 335 $ 296 $ 258 (1) Changes in fair value are included within net (loss) return 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: December 31, 2016 December 31, 2015 Fair value impact due to Fair value impact due to Actual 10% adverse change 20% adverse change Actual 10% adverse change 20% adverse change (Dollars in millions) Option adjusted spread 7.78 % $ 326 $ 318 8.24 % $ 287 $ 279 Constant prepayment rate 16.68 % 322 311 12.63 % 285 275 Weighted average cost to service per loan $ 68.18 330 326 $ 71.86 292 288 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, see Note 1 - Description of Business, Basis of Presentation, and Summary of Significant Accounting Standards and Note 22 - Fair Value Measurements.

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 after taking into account the effects of legally enforceable bilateral collateral and master netting agreements. 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 December 31, 2016 , we had $1 million (net-of-tax) recorded of unrealized gains on derivatives classified as cash flow hedges recorded in accumulated other comprehensive income (loss), compared to $3 million of unrealized losses at December 31, 2015 . The estimated amount to be reclassified from other comprehensive income into earnings during the next 12 months represents $4 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 December 31, 2016 . Cash flows and the profit impact associated with designated hedges are reported in the same category as the underlying hedged item.

We settled $250 million and $375 million in long-term fixed rate FHLB advances during the fourth quarters of 2016 and 2015 , respectively. During the year ending December 31, 2015 , the settlement resulted in a gain on extinguishment of debt in the amount of $3 million , included in other noninterest income. 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 December 31, 2016 , we had the authority and approval from the FHLB to utilize a line of credit of up to $7 billion and we may access that line to the extent that collateral is provided. At December 31, 2016 , we had $3 billion of advances outstanding and an additional $1.1 billion of collateralized borrowing capacity available at 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 December 31, 2016 , $1 billion of the outstanding advances had an adjustable rate based on the three month LIBOR index. Interest rates on these advances reset every three months and the advances may be prepaid without penalty, with notification at scheduled three month intervals after an initial 12 month lockout period. The outstanding advances included $830 million in a cash flow hedge relationship as discussed in Note 11 - Derivative Financial Instruments. The following table contains detailed information on our FHLB advances and other borrowings: For the Years Ended December 31, 2016 2015 2014 (Dollars in millions) Maximum outstanding at any month end $ 3,557 $ 3,541 $ 1,300 Average outstanding balance 2,833 1,811 939 Average remaining borrowing capacity 1,137 1,611 1,947 Weighted-average interest rate 1.16 % 1.00 % 0.23 % The following table outlines the maturity dates of our FHLB advances and other borrowings: December 31, 2016 (Dollars in millions) 2017 $ 1,830 2018 125 2019 — 2020 — Thereafter 1,025 Total $ 2,980 Parent Company Senior Notes and Trust Preferred Securities The following table presents long-term debt: December 31, 2016 December 31, 2015 (Dollars in millions) Senior Notes Amount Interest Rate Amount Interest Rate Senior notes, matures 2021 $ 246 6.125 % $ — — % Trust Preferred Securities Floating Three Month LIBOR Plus 3.25%, matures 2032 $ 26 4.25 % $ 26 3.85 % Plus 3.25%, matures 2033 26 4.13 % 26 3.57 % Plus 3.25%, matures 2033 26 4.25 % 26 3.85 % Plus 2.00%, matures 2035 26 2.88 % 26 2.32 % Plus 2.00%, matures 2035 26 2.88 % 26 2.32 % Plus 1.75%, matures 2035 51 2.71 % 51 2.26 % Plus 1.50%, matures 2035 25 2.38 % 25 1.82 % Plus 1.45%, matures 2037 25 2.41 % 25 1.96 % Plus 2.50%, matures 2037 16 3.46 % 16 3.01 % Total Trust Preferred Securities $ 247 $ 247 Total long-term debt $ 493 $ 247 Senior Notes On July 11, 2016, we issued $250 million of senior notes ("2021 Senior Notes") which mature on July 15, 2021. The proceeds from these notes were used to bring dividends current and redeem our outstanding Series C Preferred Stock. 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 2021 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. In January 2012, we exercised our contractual rights to defer interest payments. On July 14, 2016, we ended the deferral and made a $34 million payment to bring current our previously deferred interest as of that date.

Representation and Warranty Reserve Disclosures [Abstract]
Representation and Warranty Reserve	Representation and Warranty Reserve At the time a loan is sold, an estimate of the fair value of the guarantee associated with the mortgage loans is recorded in the representation and warranty reserve in the Consolidated Statements of Financial Condition. This reduces the net gain on loan sales in the Consolidated Statements of Operations. Subsequent to the sale, the liability is re-measured on an ongoing basis based on an estimate of probable losses. Changes in the estimate are recorded in the representation and warranty (provision) benefit on the Consolidated Statements of Operations. The following table shows the activity in the representation and warranty reserve: For the Years Ended December 31, 2016 2015 2014 (Dollars in millions) Balance, beginning of period $ 40 $ 53 $ 54 Provision (benefit) Gain on sale reduction for representation and warranty liability 5 7 7 Representation and warranty provision (benefit) (19 ) (19 ) 10 Total (14 ) (12 ) 17 (Charge-offs) Recoveries, net 1 (1 ) (18 ) Balance, end of period $ 27 $ 40 $ 53

Warrants and Rights Note Disclosure [Abstract]
Warrants	Warrants May Investor Warrant We granted warrants (the "May Investor Warrants") on January 30, 2009 under anti-dilution provisions applicable to certain investors (the "May Investors") in our May 2008 private placement capital raise. For the year ended December 31, 2016 , 378,334 May Investor Warrants were exercised resulting in the issuance of 236,058 shares of Common Stock. The May Investors held warrants to purchase 237,627 shares at an exercise price of $10.00 at December 31, 2016 . The May Investor Warrants do not meet the definition of a contract that is indexed to our own stock under U.S. GAAP. Therefore, the May Investor Warrants are classified as a liability which is recorded in other liabilities on the Consolidated Statements of Financial Condition and are measured at fair value. Warrant liabilities are valued using a Black Scholes model and are classified within Level 2 of the valuation hierarchy. Significant observable inputs include share price, expected volatility, a risk free rate and an expected life. At December 31, 2016 and 2015 , the liability from May Investors Warrants amounted to $4 million and $8 million , respectively. For further information, see Note 22 - Fair Value Measurements. TARP Warrant On January 30, 2009, in conjunction with the sale of 266,657 shares of Series C fixed rate cumulative non-convertible perpetual preferred stock ("Series C Preferred Stock") for $267 million , we issued a warrant to purchase up to approximately 645,138 shares of Common Stock at an exercise price of $62.00 per share (the "Warrant"). The Warrant is exercisable through January 30, 2019 and remains outstanding subsequent to the redemption of TARP, which occurred during the third quarter 2016.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings (loss) per share, excluding dilution, is computed by dividing earnings (loss) available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings (loss) 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 (loss) per share of common stock: For the Years Ended December 31, 2016 2015 2014 (In millions, except share data) Net income (loss) $ 171 $ 158 $ (69 ) Less: preferred stock dividend/accretion — — (1 ) Net income (loss) from continuing operations 171 158 (70 ) Deferred cumulative preferred stock dividends (18 ) (30 ) (26 ) Net income (loss) applicable to Common Stockholders $ 153 $ 128 $ (96 ) Weighted Average Shares Weighted average common shares outstanding 56,569,307 56,426,977 56,246,528 Effect of dilutive securities May Investor Warrants 138,314 305,484 — Stock-based awards 890,046 432,062 — Weighted average diluted common shares 57,597,667 57,164,523 56,246,528 Earnings (loss) per common share Basic earnings (loss) per common share $ 2.71 $ 2.27 $ (1.72 ) Effect of dilutive securities May Investor Warrants (0.01 ) (0.01 ) — Stock-based awards (0.04 ) (0.02 ) — Diluted earnings (loss) per common share $ 2.66 $ 2.24 $ (1.72 ) On July 29, 2016, we completed the previously announced $267 million redemption of our Series C Preferred Stock. This transaction reduced stockholders equity by approximately $ 372 million with a $267 million reduction in Preferred Stock and a $105 million reduction related to the payment of deferred dividends. Under the terms of the Series C Preferred Stock the Company was able to defer payments of preferred stock dividends. We elected to defer dividend payments beginning with the February 2012 dividend. Although, while being deferred, the impact was not included in 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.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation Our board of directors participates in various stock option plans and incentive compensation plans. Certain key employees, officers, directors and others are eligible to receive stock awards. Awards that may be granted under the plan include stock options, incentive stock options, cash-settled stock appreciation rights, restricted stock units, performance shares and performance units and other awards. Under the current plan, the exercise price of any award granted must be at least equal to the fair market value of common stock on the date of grant. Non-qualified stock options granted to directors expire 5 years from the date of grant. Grants other than non-qualified stock options have term limits set by the board of directors in the applicable agreement. Stock appreciation rights generally expire 7 years from the date of grant. Awards still outstanding under any of the prior plans will continue to be governed by their respective terms. During the years ended December 31, 2016 , 2015 and 2014 , compensation expense recognized related to stock-based compensation totaled $11 million , $3 million and $4 million , respectively.

Restricted Stock Units We have issued restricted stock units to officers, directors and certain employees. Time based restricted stock generally will vest in 3 increments on each annual anniversary of the date of grant beginning with the first anniversary subject to service and performance conditions. Certain performance based restricted stock will vest in three years from the date of grant subject to service and performance conditions. On October 20, 2015, our Board approved and adopted the Flagstar Bancorp, Inc. Executive Long-Term Incentive Program ("ExLTIP"). The ExLTIP provides for payouts to certain executives only if our stock achieves and sustains a specified market performance within ten years of the grant date. The ExLTIP awards were made in the form of restricted stock units under and subject to the terms of the 2016 Flagstar Bancorp, Inc. Stock and Incentive Plan, which was approved at the May 24, 2016 annual shareholder meeting. If vested, the restricted stock units would pay out in five installments, subject to a quality review. At December 31, 2016 and 2015 , the maximum number of shares of common stock that may be issued were 2,634,070 shares and 437,402 shares, respectively. We incurred expenses of approximately $11 million , $3 million and $3 million with respect to restricted stock units during the years ended December 31, 2016 , 2015 and 2014 , respectively. The total fair value of awards vested during the years ended December 31, 2016 , 2015 , 2014 was $3 million , $2 million , and $5 million , respectively. As of December 31, 2016 , the total unrecognized compensation cost related to non-vested awards was $13 million with a weighted average expense recognition period of 3.5 years .

Such reserves would only be taken into taxable income if the Bank, or a successor institution, liquidates, redeems shares, pays dividends in excess of earnings, or ceases to qualify as a bank for tax purposes. During the years ended December 31, 2016 and 2015 , we had federal net operating loss carry forwards of $480 million and $660 million , respectively. These carry forwards, if unused, expire in calendar years 2028 through 2035 . As a result of a change in control occurring on January 30, 2009, Section 382 of the Internal Revenue Code places an annual limitation on the use of our new operating loss carry forwards that existed at that time. At December 31, 2016 we had $138 million of net operating loss carry forwards subject to certain annual use limitations which expire in calendar years 2028 through 2029 . We had a total state deferred tax asset before valuation allowance of $32 million and total state net operating loss carryforwards of $611 million at December 31, 2016 . In connection with our ongoing assessment of deferred taxes, we analyzed each state net operating loss by jurisdiction and determined the amount of such net operating loss, which is expected to expire unused and recorded a valuation allowance to reduce the deferred tax asset to the amount which is more likely than not to be realized. At December 31, 2016 , the state deferred tax assets which will more likely than not be realized, was $12 million and we have maintained a valuation allowance of $20 million due to state loss carryover limitations. We regularly evaluate the need for deferred tax asset valuation allowances based on a more likely than not standard as defined by generally accepted accounting principles. The ability to realize deferred tax assets depends on the ability to generate sufficient taxable income within the carryback or carryforward periods provided for in the tax law for each applicable tax jurisdiction. Our income tax returns are subject to review and examination by federal, state and local government authorities. On an ongoing basis, numerous federal, state and local examinations are in progress and cover multiple tax years. At December 31, 2016 , the Internal Revenue Service had completed an examination of us through the taxable year ended December 31, 2013 . The years open to examination by state and local government authorities vary by jurisdiction. We recognize interest and penalties related to uncertain tax positions in income tax expense. For the years ended December 31, 2016 , 2015 and 2014 , we did not recognize any interest income, interest expense, or increase or decreases to uncertain income tax positions of greater than $1 million , individually or in aggregate.

Banking and Thrift [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. Various aspects of Basel III are subject to multi-year transition periods through December 31, 2018. Basel III will materially change our Tier 1, Tier 1 common and total capital calculations. To be categorized as "well-capitalized," the Company and the Bank must maintain minimum tangible capital, Tier 1 capital, common equity Tier 1, and total capital ratios as set forth in the table below. We, along with the Bank, are considered "well-capitalized" at both December 31, 2016 and December 31, 2015 . An institution is considered well-capitalized if its ratio of total risk-based capital to risk-weighted assets is 10.0 percent or more, its ratio of Tier 1 capital to risk-weighted assets is 8.0 percent or more, its ratio of common equity tier 1 capital to risk-weighted assets is 6.5 percent or more, and its leverage ratio of Tier 1 capital to total assets is 5.0 percent or more. There have been no conditions or events that management believes have changed our or the Bank’s category. The following tables present the regulatory capital ratios as of the dates indicated: Bancorp Actual For Capital Adequacy Purposes Well Capitalized Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio (Dollars in millions) December 31, 2016 Tangible capital (to tangible assets) $ 1,256 8.88 % N/A N/A N/A N/A Tier 1 capital (to adjusted tangible assets) 1,256 8.88 % $ 566 4.0 % $ 707 5.0 % Common equity Tier 1 capital (to RWA) 1,084 13.06 % 374 4.5 % 540 6.5 % Tier 1 capital (to RWA) 1,256 15.12 % 498 6.0 % 664 8.0 % Total capital (to RWA) 1,363 16.41 % 664 8.0 % 830 10.0 % December 31, 2015 Tangible capital (to tangible assets) $ 1,435 11.51 % N/A N/A N/A N/A Tier 1 capital (to adjusted tangible assets) 1,435 11.51 % $ 499 4.0 % $ 624 5.0 % Common equity Tier 1 capital (to RWA) 1,065 14.09 % 340 4.5 % 491 6.5 % Tier 1 capital (to RWA) 1,435 18.98 % 454 6.0 % 605 8.0 % Total capital (to RWA) 1,534 20.28 % 605 8.0 % 756 10.0 % N/A - Not applicable.

Consent Orders On December 19, 2016, the OCC terminated the Consent Order with the Bank which had been in place since October 23, 2012. Since entering into the Consent Order, the Bank implemented and adopted, what we believe are, industry best practices related to, among other things, regulatory compliance, enterprise risk management, capital and liquidity. The lifting of the Consent Order signifies that the OCC has determined that the Bank has met all of the Consent Order requirements. Supervisory Agreement The Company remains subject to the Supervisory Agreement, which will remain in effect until terminated, modified, or suspended in writing by the Federal Reserve. Pursuant to the Supervisory Agreement, the Company submitted a capital plan to the OTS, predecessor in interest to the Federal Reserve. In addition, the Company agreed to request prior non-objection of the Federal Reserve to pay dividends or other capital distributions; purchase, repurchase or redeem certain securities; incur, issue, renew, roll over or increase any debt and enter into certain affiliate transactions; and comply with restrictions on the payment of severance and indemnification payments, director and management changes and employment contracts and compensation arrangements. A copy of the Supervisory Agreement was filed with the SEC as an exhibit to the Company's Current Report on Form 8-K filed on January 28, 2010. The Company has taken actions which it believes are appropriate to comply with, and intends to maintain compliance with, all of the requirements of the Supervisory Agreement. Regulatory Developments The Bank and Bank Holding Company were subject to the capital requirements of the Basel III rules beginning January 1, 2015, which replaces the framework established by the 1988 capital accord ("Basel I") of the Basel Committee on Banking Supervision. The regulatory capital rules require the Bank and Holding Company to maintain Tier 1 capital of at least 6 percent of risk-weighted assets and off-balance sheet items, total capital (the sum of Tier 1 capital and Tier 2 capital) of at least 8 percent of risk-weighted assets and off-balance sheet items, Tier 1 capital of at least 4 percent of adjusted quarterly average assets and common equity Tier 1 capital of at least 4.5 percent of risk-weighted assets. Effective January 1, 2016, we became subject to the capital conservation buffer under the Basel III rules, subjecting a banking organization to certain limitations on capital distributions and discretionary bonus payments to executive officers if the organization does not maintain a capital conservation buffer above the minimum risk based capital requirements. The capital conservation buffer for 2016 must be greater than 0.625 percent in order to not be subject to limitations. The Company and the Bank had a capital conservation buffer of 8.4 percent and 11.2 percent, respectively as of December 31, 2016. When fully phased-in on January 1, 2019, the capital conservation buffer must be greater than 2.5 percent. Under the increased capital standards established by the Dodd-Frank Act, bank holding companies are prohibited from including in their regulatory Tier 1 capital hybrid debt and equity securities, such as trust preferred securities, issued on or after May 19, 2010. The Company continues to include our existing trust preferred securities as Tier 1 capital as they were issued prior to May, 19, 2010.

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 mortgage-related 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 such 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. Management does 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 . The Settlement Agreement provides that the Bank will make annual payments in increments of up to $25 million towards the $118 million still due upon meeting all conditions which are evaluated quarterly and include: (a) the reversal of the deferred tax asset 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; (c) our Bank’s Tier 1 Leverage Capital Ratio is 11 percent or more. 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, such annual payments must commence twelve months after the date of that business combination. Within six months of satisfying the conditions specified above, the Bank would make an additional payment, to occur no more frequently than annually, provided that doing so would not violate any material banking regulatory requirement or the OCC does 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. 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 December 31, 2016 of 8.2 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 assume the liability. The fair value of the DOJ Liability was $60 million and $84 million at December 31, 2016 and December 31, 2015 , respectively. The lower value resulted from a change in the expectation as to the timing of payments to the DOJ as a result of a $200 million dividend from the Bank to the Bancorp and the issuance of $250 million in Senior Notes, both of which occurred in July 2016, to a) bring current the interest payments on our trust preferred securities, b) become current on our deferred interest and dividends related to our TARP Preferred and c) repay our TARP Preferred. To support the on-going debt service and other Bancorp expenses, we also intend to reduce our Bancorp double leverage and debt to equity ratios to be more consistent with such ratios at other mid-sized banks, which would likely require further dividend payments from the Bank to the Bancorp for the foreseeable future. Other litigation accruals At December 31, 2016 and December 31, 2015 , excluding the fair value liability relating to the DOJ litigation settlement, our total accrual for contingent liabilities and settled litigation was $1 million and $2 million , respectively. Commitments A summary of the contractual amount of significant commitments is as follows: December 31, 2016 2015 (Dollars in millions) Commitments to extend credit Mortgage loan interest-rate lock commitments $ 4,115 $ 3,792 HELOC commitments 179 150 Other consumer commitments 57 22 Warehouse loan commitments 1,670 871 Standby and commercial letters of credit 30 13 Commercial and industrial commitments 424 151 Other commercial commitments 651 497 Commitments to extend credit are agreements to lend. 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. 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. The types of credit we extend is 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 are recorded in the Consolidated Statements of Financial Condition in other assets. For further information on derivative instruments, see Note 11 - Derivative Financial Instruments. 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 and due to a decline in the collateral value. Other consumer commitments. C onditional 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. 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. 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. 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. 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. The balance of $3 million and $2 million for December 31, 2016 and 2015 , respectively, is reflected in other liabilities on the Consolidated Statements of Financial Condition.

Fair Value Measurements

Fair Value Measurements	12 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 as of December 31, 2016 and 2015 , by caption on the Consolidated Statements of Financial Condition and by the valuation hierarchy: Level 1 Level 2 Level 3 Total Fair Value (Dollars in millions) December 31, 2016 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 Second mortgage loans — — 41 41 HELOC loans — — 24 24 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 ) Level 1 Level 2 Level 3 Total Fair (Dollars in millions) December 31, 2015 Investment securities available-for-sale Agency - Commercial $ — $ 766 $ — $ 766 Agency - Residential — 514 — 514 Municipal obligations — 14 — 14 Loans held-for-sale Residential first mortgage loans — 2,541 — 2,541 Loans held-for-investment Residential first mortgage loans — 6 — 6 Second mortgage loans — — 42 42 HELOC loans — — 64 64 Mortgage servicing rights — — 296 296 Derivative assets Rate lock commitments (fallout-adjusted) — — 26 26 Mortgage-backed securities forwards — 7 — 7 Interest rate swaps and swaptions — 25 — 25 Total assets at fair value $ — $ 3,873 $ 428 $ 4,301 Derivative liabilities U.S. Treasury, swap and euro dollar futures $ (1 ) $ — $ — $ (1 ) Mortgage-backed securities forwards — (6 ) — (6 ) Interest rate swap on FHLB advances (net) — (4 ) — (4 ) Interest rate swaps — (7 ) — (7 ) Warrant liabilities — (8 ) — (8 ) DOJ litigation settlement — — (84 ) (84 ) Total liabilities at fair value $ (1 ) $ (25 ) $ (84 ) $ (110 ) There were no transfers between Level 1 and Level 2 during the years ended December 31, 2016 and 2015 , and 2014 . 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. Fair Value Measurements Using Significant Unobservable Inputs The tables below include a roll forward of the Consolidated Statements of Financial Condition amounts (including the change in fair value) for financial instruments classified by us within level 3 of the valuation hierarchy: Balance at Recorded Recorded Purchases / Originations Sales Settlement Transfers In (Out) Balance at End of Year Total Total Total (Dollars in millions) Year Ended December 31, 2016 Assets Loans held-for-investment Second mortgage loans (1) $ 42 $ (1 ) $ — $ — $ — $ — $ (12 ) $ 12 $ 41 HELOC loans (1) 64 6 — — — — (34 ) (12 ) 24 Mortgage servicing rights 296 (105 ) — — 228 (84 ) — — 335 Rate lock commitments (net) (2) 26 25 — — 325 — — (358 ) 18 Totals $ 428 $ (75 ) $ — $ — $ 553 $ (84 ) $ (46 ) $ (358 ) $ 418 Liabilities DOJ litigation settlement $ (84 ) $ 24 $ — $ — $ — $ — $ — $ — $ (60 ) Year Ended December 31, 2015 Assets Investment securities available-for-sale Municipal obligation $ 2 $ — $ — $ — $ — $ — $ (2 ) $ — $ — Loans held-for-investment Second mortgage loans 53 2 1 — — — (14 ) — 42 HELOC loans 132 (4 ) (1 ) — — — (63 ) — 64 Mortgage servicing rights 258 (46 ) — — 260 (176 ) — — 296 Other investments 100 — — — — — (100 ) — — Rate lock commitments (2) 31 60 — — 277 — — (342 ) 26 Totals $ 576 $ 12 $ — $ — $ 537 $ (176 ) $ (179 ) $ (342 ) $ 428 Liabilities Long-term debt $ (84 ) $ — $ (3 ) $ — $ — $ 52 $ 35 $ — $ — DOJ litigation settlement (82 ) (2 ) — — — — — — (84 ) Totals $ (166 ) $ (2 ) $ (3 ) $ — $ — $ 52 $ 35 $ — $ (84 ) Year Ended December 31, 2014 Assets Investment securities available-for-sale Municipal obligation (3) $ — $ — $ — $ — $ — $ — $ (2 ) $ 4 $ 2 Loans held-for-investment Second mortgage loans 65 2 2 — — — (16 ) — 53 HELOC loans 155 (3 ) 2 — 1 — (23 ) — 132 Mortgage servicing rights 285 (67 ) — — 271 (231 ) — — 258 Other investments — — — — 100 — — — 100 Rate lock commitments (net) (2) 10 154 — — 220 — — (353 ) 31 Totals $ 515 $ 86 $ 4 $ — $ 592 $ (231 ) $ (41 ) $ (349 ) $ 576 Liabilities Long-term debt $ (106 ) $ — $ (7 ) $ — $ — $ — $ 29 $ — $ (84 ) DOJ litigation settlement (93 ) 11 — — — — — — (82 ) Totals $ (199 ) $ 11 $ (7 ) $ — $ — $ — $ 29 $ — $ (166 ) (1) As HELOC loans reach their balloon payment, their terms may be modified to those of an amortizing second mortgage. (2) Rate lock commitments are reported on a fallout adjusted basis. Transfers out of Level 3 represent the settlement value of the commitments that are transferred to loans held for sale, which are classified as Level 2 assets. (3) The municipal obligation was historically priced using Level 2 inputs and was transferred into a Level 3 asset due to the obligation not being a readily marketable security. 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) December 31, 2016 (Dollars in millions) Assets Second mortgage loans $ 41 Discounted cash flows Discount rate 8.10% HELOC loans $ 24 Discounted cash flows Discount rate 6.0% - 9.0% (7.5%) 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%) Fair Value Valuation Technique Unobservable Input Range (Weighted Average) December 31, 2015 (Dollars in millions) Assets Second mortgage loans $ 42 Discounted cash flows Discount rate 7.2% - 10.8% (9.0%) HELOC loans $ 64 Discounted cash flows Discount rate 6.8% - 10.1% (8.4%) Mortgage servicing rights $ 296 Discounted cash flows Option adjusted spread 6.6% - 9.9% (8.2%) Rate lock commitments $ 26 Consensus pricing Origination pull-through rate 67.6% - 100.0% (84.6%) Liabilities DOJ litigation settlement $ (84 ) Discounted cash flows Discount rate 4.9% - 9.5% (7.2%) Recurring Significant Unobservable Inputs The significant unobservable inputs used in the fair value measurement of the second mortgage 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. The HELOC loans, formerly included in the FSTAR 2005-1 and FSTAR 2006-1 securitization trusts, are 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. Estimated cash flows are then discounted back using an unobservable discount rate. Loans within the loan portfolios contain FICO scores with a minimum of 426 , maximum of 805 , and a weighted average of 656 . For the loans, increases (decreases) in the discount rate, in isolation, would lower (higher) the fair value measurement. 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. Additionally, the key economic assumptions used in determining the fair value of MSRs capitalized were as follows: For the Years Ended December 31, 2016 2015 2014 Weighted-average life (in years) 7.1 7.9 7.8 Weighted-average constant prepayment rate 13.2 % 11.3 % 12.3 % Weighted-average option adjusted spread 10.1 % 8.8 % 9.4 % The key economic assumptions reflected in the overall fair value of the MSRs were as follows: December 31, 2016 2015 2014 Weighted-average life (in years) 6.6 7.3 6.6 Weighted-average constant prepayment rate 16.7 % 12.6 % 15.0 % Weighted-average option adjusted spread 7.8 % 8.2 % 8.9 % The significant unobservable input used in the fair value measurement of the DOJ litigation settlement is the discount rate, in addition to those discussed in Note 21 - Legal Proceedings, Contingencies and Commitments. Significant increases (decreases) in the discount rate in isolation could result in a marginally lower (higher) fair value measurement. For further information on the fair value inputs related to the DOJ litigation settlement, see Note 21 - Legal Proceedings, Contingencies and 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. 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. These assets are measured at the lower of cost or market and had a fair value below cost at the end of the period as summarized below: Total (1) Level 2 Level 3 Gains/(Losses) (Dollars in millions) 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 ) December 31, 2015 Loans held-for-sale (2) $ 8 $ 8 $ — $ (2 ) Impaired loans held-for-investment (2) Residential first mortgage loans 40 — 40 (83 ) Commercial real estate loans 2 — 2 (1 ) Repossessed assets (3) 17 — 17 — Totals $ 67 $ 8 $ 59 $ (86 ) (1) The fair values are determined at various dates during the years ended December 31, 2016 and 2015 , 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(s) Unobservable Input Range (Weighted Average) December 31, 2016 (Dollars in millions) 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%) Fair Value Valuation Technique(s) Unobservable Input Range (Weighted Average) December 31, 2015 (Dollars in millions) Impaired loans held-for-investment Residential first mortgage loans $ 40 Fair value of collateral Loss severity discount 35% - 45% (35.2%) Commercial real estate loans $ 2 Fair value of collateral Loss severity discount 45% - 55% (50.1%) Repossessed assets $ 17 Fair value of collateral Loss severity discount 16% - 100% (48.7%) 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.

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 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. 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. 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: For the Years Ended December 31, 2016 2015 2014 Assets (Dollars in millions) Loans held-for-sale Net gain on loan sales $ 269 $ 321 $ 401 Other noninterest income — — (2 ) Loans held-for-investment Other noninterest income 1 40 44 Liabilities Long-term debt Other noninterest income $ — $ 29 $ 22 Litigation settlement Other noninterest income $ 24 $ — 11 Other noninterest (expense) — (2 ) — 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: December 31, 2016 December 31, 2015 December 31, 2014 (Dollars in millions) Unpaid Principal Balance Fair Value Fair Value Over/(Under) UPB Unpaid Principal Balance Fair Value Fair Value Over/(Under) UPB Unpaid Principal Balance Fair Value Fair Value Over/(Under) UPB Assets Nonaccrual loans Loans held-for-sale $ 2 $ 2 $ — $ 1 $ — $ (1 ) $ — $ — $ — Loans held-for-investment 19 13 (6 ) 21 10 (11 ) 11 5 (6 ) Total nonaccrual loans $ 21 $ 15 $ (6 ) $ 22 $ 10 $ (12 ) $ 11 $ 5 $ (6 ) Other performing loans Loans held-for-sale $ 3,103 $ 3,143 $ 40 $ 2,451 $ 2,541 $ 90 $ 1,144 $ 1,196 $ 52 Loans held-for-investment 72 59 (13 ) 112 101 (11 ) 225 206 (19 ) Total other performing loans $ 3,175 $ 3,202 $ 27 $ 2,563 $ 2,642 $ 79 $ 1,369 $ 1,402 $ 33 Total loans Loans held-for-sale $ 3,105 $ 3,145 $ 40 $ 2,452 $ 2,541 $ 89 $ 1,144 $ 1,196 $ 52 Loans held-for-investment 91 72 (19 ) 133 111 (22 ) 236 211 (25 ) Total loans $ 3,196 $ 3,217 $ 21 $ 2,585 $ 2,652 $ 67 $ 1,380 $ 1,407 $ 27 Liabilities Long-term debt $ — $ — $ — $ — $ — $ — $ (88 ) $ (84 ) $ 4 Litigation settlement (1) (118 ) (60 ) 58 (118 ) (84 ) 34 (118 ) (82 ) 36 (1) We are obligated to pay $118 million in installment payments upon meeting certain performance conditions.

Segment Reporting [Abstract]
Segment Information	Segment Information Our operations are conducted through four operating segments: Community Banking, Mortgage Originations, Mortgage Servicing, and Other, which 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, 2016, we reorganized our reportable segments to align with our new management reporting structure and to align with our long-term strategy. Prior period segment financial information has been recast to conform to the current presentation. Prior to the reorganization, representation and warranty reserves were reported in the Mortgage Servicing segment and the MSR asset and associated costs were reported in the Other segment. As a result of this change, representation and warranty reserves, as well as the MSR asset and associated costs are now reported in the Mortgage Originations segment. 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 HFI Portfolio groups. Products offered through these groups include checking accounts, savings accounts, money market accounts, certificates of deposit, consumer loans, commercial loans, home builder finance loans and warehouse lines of credit. Other financial services available to consumer and commercial customers include lines of credit, revolving credit, customized treasury management solutions, equipment leasing, inventory, and accounts receivable lending and capital markets services such as interest rate risk protection products. 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, on a fee basis, for others. Also, the Mortgage Servicing segment services, on a fee basis, residential mortgages HFI held by the Community Banking segment and MSRs held by the Mortgage Originations segment. The Mortgage Servicing segment may also collect ancillary fees, such as late fees, and earns income through the use of noninterest-bearing escrows. 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 are fully allocated to each operating segment. Allocation methodologies may be subject to periodic adjustment as the internal management accounting system is revised and the business or product lines within the segments change. The following tables present financial information by business segment for the periods indicated: Year Ended December 31, 2016 Community Banking Mortgage Origination Mortgage Servicing Other Total Summary of Operations (Dollars in millions) Net interest income $ 206 $ 82 $ 33 $ 2 $ 323 Net gain (loss) on loan sales 6 310 — — $ 316 Representation and warranty benefit — 19 — — $ 19 Other noninterest income 28 26 54 44 $ 152 Total net interest income and noninterest income 240 437 87 46 810 Benefit (provision) for loan losses 10 — (2 ) — 8 Asset resolution — (1 ) (6 ) — (7 ) Depreciation and amortization expense (7 ) (5 ) (4 ) (16 ) (32 ) Other noninterest expense (173 ) (246 ) (97 ) (5 ) (521 ) Total noninterest expense (180 ) (252 ) (107 ) (21 ) (560 ) Income (loss) before income taxes 70 185 (22 ) 25 258 Provision (benefit) for income taxes — — — 87 87 Net income (loss) $ 70 $ 185 $ (22 ) $ (62 ) $ 171 Intersegment revenue $ (3 ) $ 1 $ 22 $ (20 ) $ — Average balances Loans held-for-sale $ 66 $ 3,068 $ — $ — 3,134 Loans with government guarantees — — 435 — 435 Loans held-for-investment 5,807 6 — — 5,813 Total assets 5,906 3,824 639 3,538 13,907 Deposits 7,151 — 1,611 — 8,762 Year Ended December 31, 2015 Community Banking Mortgage Origination Mortgage Servicing Other Total Summary of Operations (Dollars in millions) Net interest income $ 171 $ 72 $ 13 $ 31 $ 287 Net gain (loss) on loan sales (15 ) 303 — — $ 288 Representation and warranty benefit — 19 — — $ 19 Other noninterest income 25 78 56 4 $ 163 Total net interest income and noninterest income 181 472 69 35 757 Benefit for loan losses 19 — — — 19 Asset resolution (1 ) (1 ) (13 ) — (15 ) Depreciation and amortization expense (6 ) (3 ) (3 ) (12 ) (24 ) Other noninterest expense (153 ) (228 ) (107 ) (9 ) (497 ) Total noninterest expense (160 ) (232 ) (123 ) (21 ) (536 ) Income (loss) before income taxes 40 240 (54 ) 14 240 Provision for income taxes — — — 82 82 Net income (loss) $ 40 $ 240 $ (54 ) $ (68 ) $ 158 Intersegment revenue $ (15 ) $ 10 $ 17 $ (12 ) $ — Average balances Loans held-for-sale $ 40 $ 2,148 $ — $ — 2,188 Loans with government guarantees — — 633 — 633 Loans held-for-investment 4,986 4 — 86 5,076 Total assets 4,972 2,661 944 3,379 11,956 Deposits 6,674 — 1,203 — 7,877 Year Ended December 31, 2014 Community Banking Mortgage Origination Mortgage Servicing Other Total Summary of Operations (Dollars in millions) Net interest income $ 150 $ 56 $ 20 $ 21 $ 247 Net gain (loss) on loan sales (3 ) 209 — — $ 206 Representation and warranty (provision) benefit — (10 ) — — $ (10 ) Other noninterest income 22 70 58 15 $ 165 Total net interest income and noninterest income 169 325 78 36 608 Provision for loan losses (132 ) — — — (132 ) Asset resolution (4 ) (3 ) (50 ) — (57 ) Depreciation and amortization expense (5 ) (1 ) (6 ) (12 ) (24 ) Other noninterest expense (158 ) (206 ) (123 ) (11 ) (498 ) Total noninterest expense (167 ) (210 ) (179 ) (23 ) (579 ) Income (loss) before income taxes (130 ) 115 (101 ) 13 (103 ) Benefit for income taxes — — — (34 ) (34 ) Net income (loss) $ (130 ) $ 115 $ (101 ) $ 47 $ (69 ) Intersegment revenue $ (3 ) $ (2 ) $ 18 $ (13 ) $ — Average balances Loans held-for-sale $ 62 $ 1,472 $ 20 $ — 1,554 Loans with government guarantees — — 1,216 — 1,216 Loans held-for-investment 3,975 1 — 146 4,122 Total assets 3,943 1,630 1,349 2,964 9,886 Deposits 5,984 — 750 — 6,734

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation and Basis of Presentation	Consolidation and Basis of Presentation The accounting and financial reporting policies of us and our subsidiaries conform to accounting principles generally accepted in the United States. Additionally, where applicable the policies conform to the accounting and reporting guidelines prescribed by regulatory authorities. Certain prior period amounts have been reclassified to conform to the current period presentation. The preparation of the Consolidated Financial Statements, requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, revenues and expenses and disclosures of contingent assets and liabilities. Actual results could be materially different from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from correspondent banks and the FRB, and Short-term investments that have a maturity at the date of acquisition of three months or less and are readily convertible to cash.
Investment Securities	Investment Securities We measure securities classified as AFS at fair value, with unrealized gains and losses, net of tax, included in "other comprehensive income (loss)" in stockholders’ equity. We recognize realized gains and losses on AFS securities when securities are sold. The cost of securities sold is based on the specific identification method. Any gains or losses realized upon the sale of a security are reported in "other noninterest income" in the Consolidated Statements of Operations. The fair value of investment securities is based on observable market prices, when available. If observable market prices are not available, our valuations are based on alternative methods, including: quotes for similar fixed-income securities, matrix pricing, discounted cash flow using benchmark interest rate curves or other factors. The fair values, obtained through an independent third party utilizing a pricing service, are compared to independent pricing sources on a quarterly basis. For further information, see Note 2 - Investment Securities and Note 22 - Fair Value Measurements. Investment securities HTM are carried at amortized cost and adjusted for amortization of premiums and accretion of discounts using the interest method. Transfers of investment securities into the HTM category from the AFS category are accounted for at fair value at the date of transfer. Any related unrealized holding gain (loss), net of tax, that was included in the transfer is retained in other comprehensive income (loss) and is amortized as an adjustment to interest income over the remaining life of the securities. We 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) does 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). For the years ended December 31, 2014 through December 31, 2016, we did not recognize any OTTI losses. Investment securities transactions are recorded on the trade date for purchases and sales. Interest earned on investment securities, including the amortization of premiums and the accretion of discounts are determined using the effective interest method over the period of maturity, recorded in interest income in the Consolidated Statements of Operations. For further information, see Note 2 - Investment Securities.
Loans Held-for-Sale	Loans Held-for-Sale We classify loans as HFS when we originate or purchase loans that we intend to sell. We have elected the fair value option for the majority of our LHFS. We estimate the fair value of mortgage loans based on quoted market prices for securities backed by similar types of loans, where available, or by discounting estimated cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. LHFS that are recorded at lower of cost or fair value may be carried at fair value on a nonrecurring basis when the fair value is less than cost. For further information, see Note 22 - Fair Value Measurements. Loans that are transferred into the HFS portfolio from the HFI portfolio, due to a change in intent, are recorded at the lower of cost or fair value. Gains or losses recognized upon the sale of loans are determined using the specific identification method.
Loans Held-for-Investment	Loans Held-for-Investment We classify loans that we have the intent and ability to hold for the foreseeable future or until maturity as HFI. Loans held-for-investment are reported at their amortized cost, which includes the outstanding principal balance adjusted for any unamortized premiums, discounts, deferred fees and costs. Premiums and discounts on purchased loans and non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, are deferred and recognized over the estimated lives of the related loans as an adjustment to the loans’ effective yield, which is included in interest income on loans in the Consolidated Statements of Operations. Loans originally classified as HFS, for which we have elected the fair value option, and subsequently transferred to HFI continue to be measured and reported at fair value on a recurring basis. Changes in fair value are recorded to "other noninterest income" on the Consolidated Statements of Operations. The fair value of these loans is determined using the same methods described above for LHFS. For additional information relating to recurring fair value disclosures, see Note 22 - Fair Value Measurements. When loans originally classified as HFS or as HFI are reclassified due to a change in intent or ability to hold, cash flows associated with the loans will be classified in the Consolidated Statements of Cash Flows as operating or investing, as appropriate, in accordance with the initial classification of the loans.
Past Due and Impaired Loans	Past Due and Impaired Loans Loans are considered to be past due when any payment of principal or interest is 30 days past the scheduled payment date. While it is the goal of management to collect on loans, we attempt to work out a satisfactory repayment schedule or modification with past due borrowers and will undertake foreclosure proceedings if the delinquency is not satisfactorily resolved. Our practices regarding past due loans are designed to both assist borrowers in meeting their contractual obligations and minimize losses incurred by the bank. We cease the accrual of interest on all classes of consumer and commercial loans once they become 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 may only return to accrual status when principal and interest become current and are anticipated to be fully collectible. Loans are considered impaired if it is probable that payment of interest and principal will not be made in accordance with the original contractual terms of the loan agreement or when any portion of principal or interest is 90 days past due. This classification includes both performing and nonperforming modified loans. For further information, see Note 22 - Fair Value Measurements. When a loan is considered impaired, the accrual of interest income is discontinued until the receipt of principal and interest is no longer in doubt. Interest income is recognized on impaired loans using a cost recovery method unless amounts contractually due are not in doubt. Cash received on impaired loans are applied entirely against principal until the loan has been collected in full, after which time any additional cash receipts are recognized as interest income.
Loan Modifications (Troubled Debt Restructurings)	Loan Modifications (Troubled Debt Restructurings) We may modify certain loans in both our consumer and commercial loan portfolios to retain customers or to maximize collection of the outstanding loan balance. We have programs designed to assist borrowers by extending payment dates or reducing the borrower's contractual payments. All loan modifications are made on a case-by-case basis. Our standards relating to loan modifications consider, among other factors, minimum verified income requirements, cash flow analysis, and collateral valuations. TDRs result in those instances in which a borrower demonstrates financial difficulty and for which a concession has been granted, 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.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses represents management's estimate of probable losses in our LHFI portfolio, excluding loans carried under the fair value option. We establish an allowance when (a) available information indicates that it is probable that a loss has occurred and (b) the amount of the loss can be reasonably estimated. The allowance provides for probable losses that have been identified with specific customer relationships (individually evaluated) and for probable losses believed to be inherent in the loan portfolio but that have not been specifically identified (collectively evaluated). Management assigns qualitative factors to each loan portfolio segment based on consideration of the following factors: changes in lending policies and procedures, changes in economic and business conditions, changes in the nature and volume of the portfolio, changes in lending management, changes in credit quality statistics, changes in the quality of the loan review system, changes in the value of underlying collateral for collateral-dependent loans, changes in concentrations of credit, 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 disposal costs if the loan is collateral dependent. A general allowance is established for losses inherent on non-impaired loans by segmenting the portfolio based upon common risk characteristics. The general loss is then determined by using a historical loss model which utilizes our loss history by specific product, or if the product is not sufficiently seasoned, per readily available industry peer loss data. The loss model utilizes a loss emergence period that represents the average amount of time between when the loss event first occurs and when the specific loan is charged-off. In addition to the loss history or peer data, we also include a qualitative adjustment that considers economic risks, industry and geographic concentrations and other factors not adequately captured in our methodology. Consumer loans secured by real estate are charged-off to the estimated fair value of the collateral when a loss is confirmed or at 180 days past due, whichever is sooner. Loss confirming events include, but are not limited to, bankruptcy (unsecured), continued delinquency, foreclosure or receipt of an asset valuation indicating a collateral deficiency and the asset is the sole source of repayment. For consumer loans not secured by real estate, the charge-off is taken upon confirmation or 120 days past due. Commercial loans are evaluated on a loan level basis and either charged-off or written down to net realizable value if a loss confirming event has occurred. Loss confirming events include, but are not limited to, bankruptcy (unsecured), continued delinquency, foreclosure, or receipt of an asset valuation indicating a collateral deficiency and that asset is the sole source of repayment.
Loan Sales	Transfers of Financial Assets Our recognition of gain or loss on the sale of loans for which we surrender control is accounted for as a sale to the extent that 1) the transferred assets are legally isolated from the us or our consolidated affiliates, even in bankruptcy or other receivership, 2) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company, and 3) we do not maintain the obligation or unilateral ability to reclaim or repurchase the assets. If the sale criteria are met, the transferred financial assets are removed from the Consolidated Statements of Financial Condition and a gain or loss on sale is recognized.
Variable Interest Entities	Variable Interest Entities An entity that has a controlling financial interest in a variable interest entity ("VIE") is referred to as the primary beneficiary and consolidates the VIE. The Corporation is deemed to have a controlling financial interest and is the primary beneficiary of a VIE if it has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.
Repossessed Assets	Repossessed Assets Repossessed assets include one-to-four family residential property, commercial property and one-to-four family homes under construction that were acquired through foreclosure or acceptance of a deed-in-lieu of foreclosure. Repossessed assets are initially recorded in other assets at the estimated fair value of the collateral less estimated costs to sell. Losses arising from the initial acquisition of such properties are charged against the ALLL at the time of transfer. Subsequent declines in value, as well as gains and losses on disposal of these properties, are charged to "asset resolution" within noninterest expense in the Consolidated Statements of Operations as incurred.
Loans with Government Guarantees	Loans with Government Guarantees We originate government guaranteed loans which are pooled and sold as Ginnie Mae MBS. Pursuant to Ginnie Mae servicing guidelines, we have the unilateral right to repurchase loans 90 days or more past due securitized in Ginnie Mae pools. As a result, once the delinquency criteria have been met, and regardless of whether the repurchase option has been exercised, we account for the loans as if they had been repurchased. We recognize the loans and corresponding liability as loans with government guarantees and other liabilities, respectively, in the Consolidated Statements of Financial Condition. If the loan is repurchased, the liability is cash settled and the loan with government guarantee remains. Once repurchased, we may collect losses through a claims process with the government agency, as an approved lender.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock We own stock in the FHLB of Indianapolis as required to permit us to obtain membership in and to borrow from the FHLB. No market quotes exist for the stock. The stock is redeemable at par and is carried at cost.
Premises and Equipment	Premises and Equipment Premises and equipment are carried at cost less accumulated depreciation. Land is carried at historical cost. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets which generally ranges from three to thirty years. Capitalized software is amortized on a straight-line basis over its useful life, which generally ranges from three to seven years. Software expenditures, repair and maintenance costs that are considered general, administrative, or of a maintenance nature are expensed as incurred.
Mortgage Servicing Rights (MSRs)	Mortgage Servicing Rights We purchase and originate mortgage loans for sale to the secondary market and sell the loans on either a servicing-retained or servicing-released basis. If we retain the right to service the loan, an MSR is created at the time of sale which is recorded at fair value. We use an internal valuation model that utilizes an option-adjusted spread and other assumptions to determine the fair value of MSRs. The key assumptions used in the valuation of MSRs include mortgage prepayment speeds and discount rates. Management obtains third-party valuations of the MSR portfolio on a quarterly basis from independent valuation services to assess the reasonableness of the fair value calculated by our internal valuation model. Changes in fair value of our MSRs are reported on the Consolidated Statements of Operations in "net return on mortgage servicing." For Further information, see Note 22 - Fair Value Measurements. We periodically enter into agreements to sell certain of our MSRs, which qualify as sales transactions. A transfer of servicing rights related to loans previously sold qualifies as a sale at the date on which title passes, if substantially all risks and rewards of ownership have irrevocably passed to the transferee and any protection provisions retained by the transferor are minor and can be reasonably estimated. In addition, if a sale is recognized and only minor protection provisions exist, a liability is accrued for the estimated obligation associated with those provisions.
Servicing Fee Income	Servicing Fee Income Servicing fee income, late fees and ancillary fees received on loans for which we own the MSR, are included in the net return on MSR line of the Consolidated Statements of Operations. The fees are based on a contractual percentage of the outstanding principal and are recorded as income when earned. Subservicing fees, which are included in loan administration income on the Consolidated Statements of Operations are based on a contractual monthly amount per loan including late fees and other ancillary income.
Derivatives	Derivatives We utilize derivative instruments to manage the fair value changes in our MSR asset, interest rate lock commitments and loans held for sale portfolio which are exposed to price and interest rate risk, facilitate asset/liability management, minimize the variability of future cash flows on long-term debt, and to meet the needs of our customers. All derivatives are recognized on the Consolidated Statements of Financial Condition as other assets and liabilities, as applicable, at their estimated fair value. For those derivatives designated as qualified cash flow hedges, changes in the fair value of the derivatives, to the extent effective as a hedge, are recorded in accumulated other comprehensive income, net of income taxes, and reclassified into earnings concurrently with the earnings of the hedged item. For derivative instruments designated as qualified fair value hedges, which are used to hedge the exposure of fair value changes of an asset or liability attributable to a particular risk, the gain or loss on the derivative instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in current earnings during the period of the change in fair values. For all other derivatives, changes in the fair value of the derivative are recognized immediately in earnings. A majority of these derivatives are subject to master netting agreements and cleared through a Central Counterparty Clearing House, which mitigates non-performance risk with counterparties and enables us to settle activity on a net basis. We use interest rate swaps, swaptions, futures, and forward loan sale commitments to mitigate the impact of fluctuations in interest rates and interest rate volatility on the fair value of the MSRs. These derivatives are not designated as qualifying hedges. Accordingly, changes in their fair value are reflected in current period earnings under the "net return on MSRs." Interest rate swaps, swaptions, futures, and forward loan sale commitments are valued based on quoted prices for similar assets in an active market with inputs that are observable. We also enter into various derivative agreements with customers and correspondents in the form of interest-rate lock commitments and forward purchase contracts which are commitments to originate or purchase mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The derivatives are valued using internal models that utilize market interest rates and other unobservable inputs. Changes in the fair value of these commitments due to fluctuations in interest rates that are to be originated to our HFS portfolio are economically hedged through the use of forward loan sale commitments of MBS. The gains and losses arising from this derivative activity are reflected in current period earnings under the "net gain on loan sales." Interest rate lock commitments are valued using internal models with significant unobservable market parameters. Forward loan sale commitments are valued based on quoted prices for similar assets in an active market with inputs that are observable. At certain times we may also enter into various derivative agreements with correspondents in the form of forward purchase contracts at the time the correspondent customer enters into an interest-rate lock commitment. The derivatives are valued using internal models that utilize market interest rates and other unobservable inputs. We utilize interest rate swaps to hedge the forecasted cash flows from our underlying variable-rate FHLB advances and forecasted FHLB advances in qualifying cash flow hedge accounting relationships. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense concurrently with the interest expense on the debt. Interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable. These hedges are evaluated for effectiveness using regression analysis at the time they are designated and throughout the hedge period. For forecasted FHLB advances being hedged, each reporting period we evaluate the likelihood of the transaction occurring based on the current facts and circumstances to ensure the hedge relationship still qualifies for hedge accounting. If we de-designate a hedge relationship or determine that an interest rate swap no longer qualifies for hedge accounting changes in fair value are no longer recorded in other comprehensive income. If the hedged item remains probable to occur, the effective amounts previously recorded in other comprehensive income are recognized in earnings over the remaining life of the hedged item as an adjustment to yield. We also utilize interest rate swaps to manage fair value changes of our fixed-rate FHLB advances in a qualifying fair value hedge accounting relationship. Changes in the fair value of derivatives designated as fair value hedges, as well as the change in fair value of the hedged item, are recognized in current period earnings. The corresponding adjustment is recorded as a basis adjustment to the hedged item and hedging instrument. Interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable. These hedges are evaluated for effectiveness using regression analysis at the time they are designated and throughout the hedge period. If the Company determines an interest rate swap no longer qualifies for fair value hedge accounting or is de-designated, the hedged item will no longer be adjusted for changes in fair value and the amounts previously recorded as a basis adjustment are recognized in earnings over the remaining life of the hedged item as an adjustment to yield. If a previously hedged item is extinguished or sold, the remaining unamortized balance in other comprehensive income balance for prior cash flow hedges and the remaining basis adjustment of the hedged item for prior fair value hedges will be reclassified to current period earnings. To assist our customers in meeting their needs to manage interest rate risk, we enter into interest rate swap derivative contracts. To economically hedge this risk, we enter into offsetting derivative contracts to effectively eliminate the interest rate risk associated with these contracts.
Income Taxes	Income Taxes We evaluate two components of income tax expense: current and deferred. Current income tax expense represents our estimated taxes to be paid or refunded for the current period. Deferred taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates that will apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date. We evaluate our deferred tax assets to determine if, based on all available evidence, it is more likely than not that they will be realized. If it is determined that it is more likely than not that the deferred taxes will not be realized, we establish a valuation allowance. For further information, see Note 19 - Income Taxes.
Representation and Warranty Reserve	Representation and Warranty Reserve When we sell mortgage loans into the secondary mortgage market, we make customary representations and warranties to the purchasers about various characteristics of each loan, such as the manner of origination, the nature and extent of underwriting standards applied and the types of documentation being provided. For eligible loans sold to the Agencies after December 31, 2014, certain of these representations and warranties expire after 36 months. Typically, all other representations and warranties are in place for the life of the loan. If a defect in the origination process is identified, we may be required to either repurchase the loan, pay a fee or indemnify the purchaser for losses it sustains on the loan. If there are no such defects, the Company has no liability to the purchaser for losses it may incur on such loan. Upon the sale of a loan, the Company recognizes a liability for that guarantee at its fair value as a reduction of our net gain on loan sales. Subsequent to the sale, the liability is re-measured on an ongoing basis based on an estimate of probable future losses. In each case, these estimates are based on our most recent data including loss severity on repurchased and indemnified loans, repurchase requests and other factors. Changes to our previous estimates are recorded in the representation and warranty (provision) benefit in the Consolidated Statements of Operations.
Advertising Costs	Advertising Costs Advertising costs are expensed in the period they are incurred and are included as part of other noninterest expense in the Consolidated Statements of Operations.
Stock-based Compensation	Stock-Based Compensation All share-based payments to employees, including grants of employee stock options and restricted stock units, are classified as equity with expenses being recognized in compensation and benefits in the Consolidated Statements of Operations based on their fair values. The amount of compensation is measured at the grant date and is expensed over the requisite service period, which is normally the vesting period.
Department of Justice Litigation Settlement	Department of Justice Litigation Settlement The executed settlement agreement with the DOJ representing the obligation to make future additional payments establishes a legally enforceable contract with a stipulated payment plan that meets the definition of a financial liability. We have elected the fair value option to account for this financial liability included in "other liabilities" on the Consolidated Financial Statements. For further information on the valuation of the DOJ litigation settlement, see Note 22 - Fair Value Measurements.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Business Combinations - In January 2017, the FASB issued ASU 2017-1, Business Combinations (Topic 805): Clarifying the Definition of a Business. Under the current implementation guidance in Topic 805, there are three elements of a business—inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a "set") that is a business usually has outputs, outputs are not required to be present. This amendment provides a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. ASU 2017-1 is effective for fiscal years beginning after December 15, 2017. We are currently evaluating this guidance. Statement of Cash Flows - Restricted Cash - In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force). ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendment does not provide a definition of restricted cash or restricted cash equivalents. The amendments in this update apply to all entities that have restricted cash or restricted cash equivalents and are required to present a statement of cash flows under Topic 230. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017. We are currently evaluating this guidance. Consolidation - In October 2016, the FASB issued ASU 2016-17, Consolidation (Topic 810): Interests held through related parties that are under Common Control. ASU 2016-17 amends the consolidation guidance on how a reporting entity that is the single decision maker of a VIE should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The amendments in this update are effective for fiscal years beginning after December 15, 2016. Income Taxes - In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. ASU 2016-16 improves the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The amendments in this update are effective for annual reporting periods beginning after December 15, 2017. We are currently evaluating this guidance and the impact it will have on our Consolidated Financial Statements. Statement of Cash Flows - In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. This amendment addresses eight issues which current GAAP does not include specific guidance or is unclear, pertaining to: Debt Prepayment or Debt Extinguishment Costs, Settlement of Zero-Coupon Debt Instruments, Contingent Consideration Payments Made after a Business Combination, Proceeds from the Settlement of Insurance Claims, Proceeds from the Settlement of Corporate-Owned or Bank-Owned Life Insurance Policies, Distributions Received from Equity Method Investees, Beneficial Interest in Securitization Transactions, and Separately Identifiable Cash Flows and Application of the Predominance Principle. ASU 2016-16 is effective for fiscal years beginning after December 15, 2017 and early adoption is permitted. We are currently evaluating this guidance and the impact it will have on our Consolidated Financial Statements. 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, 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, but highlight that any impact will be contingent upon the underlying characteristics of the affected portfolio and macroeconomic and internal forecasts at adoption date. Stock Compensation - In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments in ASU 2016-09 affect all entities that issue share-based payment awards to their employees. The areas for simplification in ASU 2016-09 involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective retrospectively for fiscal years beginning after December 15, 2016 and early adoption is permitted. This Update was adopted in the current reporting period with no significant impact recognized on our Consolidated Financial Statements. Derivatives and Hedging - In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815) - Contingent Put and Call Options in Debt Instruments. The amendments in ASU 2016-06 clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in ASU 2016-06 is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. ASU 2016-06 is effective retrospectively for fiscal years beginning after December 15, 2016 and early adoption is permitted. This guidance is not expected to have a material impact upon adoption on our Consolidated Financial Statements, but disclosures to the Notes thereto will be updated per the requirements. 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 almost 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. Financial Instruments - In January 2016, the FASB issued Update 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The new standard significantly revises an entity’s accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. It also amends certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 is effective retrospectively for fiscal years beginning after December 15, 2017 and early adoption is permitted. We are currently evaluating this guidance and does not expect this guidance to have a material impact on the Company’s Consolidated Financial Statements, if any. 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 expect to implement the revenue recognition guidance in the first quarter of 2018 utilizing the cumulative-effect approach. Our implementation of the guidance will include creation of 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 includes 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 Statements of Financial Condition.
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.

(3) The municipal obligation was historically priced using Level 2 inputs and was transferred into a Level 3 asset due to the obligation not being a readily marketable security.
Fair Value Inputs, Assets and Liabilities Measured on Recurring Basis, Quantitative Information	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) December 31, 2016 (Dollars in millions) Assets Second mortgage loans $ 41 Discounted cash flows Discount rate 8.10% HELOC loans $ 24 Discounted cash flows Discount rate 6.0% - 9.0% (7.5%) 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%) Fair Value Valuation Technique Unobservable Input Range (Weighted Average) December 31, 2015 (Dollars in millions) Assets Second mortgage loans $ 42 Discounted cash flows Discount rate 7.2% - 10.8% (9.0%) HELOC loans $ 64 Discounted cash flows Discount rate 6.8% - 10.1% (8.4%) Mortgage servicing rights $ 296 Discounted cash flows Option adjusted spread 6.6% - 9.9% (8.2%) Rate lock commitments $ 26 Consensus pricing Origination pull-through rate 67.6% - 100.0% (84.6%) Liabilities DOJ litigation settlement $ (84 ) Discounted cash flows Discount rate 4.9% - 9.5% (7.2%)
Fair Value Inputs, Assets, Quantitative Information	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. Additionally, the key economic assumptions used in determining the fair value of MSRs capitalized were as follows: For the Years Ended December 31, 2016 2015 2014 Weighted-average life (in years) 7.1 7.9 7.8 Weighted-average constant prepayment rate 13.2 % 11.3 % 12.3 % Weighted-average option adjusted spread 10.1 % 8.8 % 9.4 % The key economic assumptions reflected in the overall fair value of the MSRs were as follows: December 31, 2016 2015 2014 Weighted-average life (in years) 6.6 7.3 6.6 Weighted-average constant prepayment rate 16.7 % 12.6 % 15.0 % Weighted-average option adjusted spread 7.8 % 8.2 % 8.9 %
Fair Value Measurements, Nonrecurring	We also have assets that under certain conditions are subject to measurement at fair value on a nonrecurring basis. These assets are measured at the lower of cost or market and had a fair value below cost at the end of the period as summarized below: Total (1) Level 2 Level 3 Gains/(Losses) (Dollars in millions) 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 ) December 31, 2015 Loans held-for-sale (2) $ 8 $ 8 $ — $ (2 ) Impaired loans held-for-investment (2) Residential first mortgage loans 40 — 40 (83 ) Commercial real estate loans 2 — 2 (1 ) Repossessed assets (3) 17 — 17 — Totals $ 67 $ 8 $ 59 $ (86 ) (1) The fair values are determined at various dates during the years ended December 31, 2016 and 2015 , respectively.
