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. ("Flagstar" or the "Company"), 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. The Company is the largest bank headquartered in Michigan. The Bank is subject to regulation, examination and supervision by the Office of the Comptroller of the Currency ("OCC") of the U.S. Department of the Treasury ("U.S. Treasury"). The Bank is also subject to regulation, examination and supervision by the Federal Deposit Insurance Corporation ("FDIC") and the Consumer Financial Protection Bureau (the "CFPB"). The Bank's deposits are insured by the FDIC through the Deposit Insurance Fund. The Company is subject to regulation, examination and supervision by the Board of Governors of the Federal Reserve ("Federal Reserve"). The Bank is also a member of the Federal Home Loan Bank ("FHLB") of Indianapolis. Consolidation and Basis of Presentation The Consolidated Financial Statements include our accounts and accounts of all variable interest entities ("VIEs") for which we are the primary beneficiary. The accounting and financial reporting policies of Flagstar and its subsidiaries conform to accounting principles generally accepted in the United States ("GAAP"). 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 Subsequent to December 31, 2015, the Company transferred approximately $800 million conforming residential loans that remained eligible for sale to the Agencies previously classified as held-for-investment to held-for-sale. This transfer was due to a change in management’s intent in 2016 related to those specific loans driven by significant changes in market conditions during the first quarter of 2016 primarily related to a decline in interest rates. Management expects there will be no adverse material impact to the Consolidated Statements of Operations resulting from the change in classification. The Company has 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 amounts due from correspondent banks and the Federal Reserve Bank. 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 classified as trading are recorded at fair value, with unrealized and realized gains or losses included as a component of "other noninterest income" in the Consolidated Statements of Operations. The Company measures securities classified as available-for-sale at fair value, with unrealized gains and losses, net of tax, included in "other comprehensive income (loss)" in stockholders’ equity. The Company recognizes realized gains and losses on available-for-sale 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 are obtained through independent third parties from pricing services which the Company compares to independent pricing sources on a quarterly basis. See Note 2 and Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional information on recurring fair value and investment security disclosures. Investment securities held-to-maturity 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 held-to-maturity category from the available-for-sale 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. The Company evaluates available-for-sale and held-to-maturity investment securities for other-than-temporary impairment ("OTTI") 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 the Company (1) has 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 in "net impairment losses" in the Consolidated Statements of Operations for the amount representing the credit loss on the security and a charge is recognized in other comprehensive income (loss) related to gains (losses), reclassifications, impairments, credit loss and deferred tax. 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 using the effective interest method over the period of maturity, is included in interest income. For a discussion of valuation of securities, see Note 2 of the Notes to the Consolidated Financial Statements, herein. Loans Held-for-Sale The Company classifies loans as held-for-sale when it originates or purchases loans that it intends to sell. The Company has elected the fair value option for the majority of its loans held-for-sale. The Company estimates 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. Loans held-for-sale 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. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures. Loans that are transferred into the held-for-sale portfolio from the held-for-investment portfolio are recorded at the lower of cost or fair value when there is an intent to sell these loans. Gains or losses recognized upon the sale of loans are determined using the specific identification method. Loans Held-for-Investment The Company classifies loans that it has the intent and ability to hold until maturity as held-for-investment. Loans held-for-investment are reported at their outstanding principal balance adjusted for any unamortized premiums, discounts, deferred fees and costs (amortized cost). The Company recognizes interest income on held-for-investment loans using the interest method, including the amortization of any deferred cost basis adjustments; unless the Company believes that the ultimate collection of contractual principal or interest payments in full is not reasonably assured. Interest income recorded on our loans is adjusted by the amortization of net premiums, net deferred loan origination costs and the amount of negative amortization (i.e., capitalized interest) arising from our option ARM loans. Loans originally classified as held-for-sale and subsequently transferred to held-for-investment continue to be measured and reported at fair value on a recurring basis. As a result of the election of the fair value option, 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 loans held-for-sale. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures. When loans originally designated as held-for-sale or loans originally designated as held-for-investment are reclassified, 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. Loan Modifications (Troubled Debt Restructurings) The Company may modify certain loans in both consumer and commercial loan portfolio segments. Troubled Debt Restructurings ("TDRs") result in those instances in which a borrower demonstrates financial difficulty and for which a concession has been granted. Concessions include reduction of interest rate, extension 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. If a loan was nonperforming prior to restructuring, these 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 begin to accrue interest. Consumer loan modifications. For consumer loan programs (e.g., residential first mortgages, second mortgages, HELOC, and other consumer), the Company enters into a modification when the borrower has indicated a hardship, including illness or death in the family or a loss of employment. Other modifications occur when it is confirmed that the borrower does not possess the financial resources necessary to continue making loan payments at the current amount, but the Company’s expectation is that payments at lower amounts can be made. The primary concession given to consumer loan borrowers includes a reduced interest rate and/or an extension of the amortization period or maturity date. Commercial loan modifications. Modifications of terms for commercial loans are based on individual facts and circumstances. Commercial loan modifications may involve a reduction of the interest rate and/or an extension of the term of the loan. The Company also engages in other loss mitigation activities with troubled borrowers, which include repayment plans, forbearance arrangements, and the capitalization of past due amounts. 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, the Company attempts 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. The Company's practices regarding past due loans are designed to both assist borrowers in meeting their contractual obligations and minimize losses incurred by the bank. The Company ceases the accrual of interest on consumer and commercial loans once they become 90 days past due, or earlier when concerns exist as to the ultimate collection of principal or interest. 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 contractual terms of the loan agreement or when any portion of principal or interest is 90 days past due. See Note 24 of the Consolidated Financial Statements, herein, for additional nonrecurring fair value disclosures. When a loan within any class is impaired, the accrual of interest income is discontinued unless 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 receipts received on nonperforming impaired loans within any class 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. Cash receipts received on accruing impaired loans within any class are applied in the same manner as accruing loans that are not considered impaired. Allowance for Loan Losses The allowance for loan losses represents management's estimate of probable losses in the Company's loans held-for-investment portfolio, excluding loans carried under the fair value option. The Company establishes 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 a loan when it is probable all amounts due will not be collected pursuant to the 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 the Company's 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, the Company also includes a qualitative adjustment that considers economic risks, industry and geographic concentrations and other factors not adequately captured in the Company's methodology. For both consumer and commercial loans deemed impaired, the loans are evaluated on at least a quarterly basis for impairment. The Company measures the level of impairment based on the present value of the expected future cash flows discounted at the loan’s effective interest rate, the observable market price of the loan, or the fair value of the collateral if the loan is collateral dependent, reduced by estimated disposal costs. If the fair value less the costs to sell are less than the carrying value of the loan, an impairment is recorded, otherwise no allowance is recorded. 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, whatever 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 and Variable Interest Entities The Company’s recognition of gain or loss on the sale of loans for which it surrenders control is accounted for as a sale to the extent that consideration received does not include a beneficial interest in the transferred assets. In the event the Company retains a beneficial interest in the transferred assets, the carrying value of the assets sold is allocated between the assets sold and the retained interests, other than the mortgage servicing rights, based on their relative fair values. Retained mortgage servicing rights are recorded at fair value. In assessing whether control has been surrendered, the Company considers (1) whether the transferee would be a consolidated affiliate, (2) the existence and extent of any continuing involvement in the transferred financial assets and (3) the impact of all arrangements or agreements made contemporaneously with or in contemplation of the transfer, even if they were not entered into at the time of transfer. 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. For certain transfers, such as in connection with complex transactions or where the Company has continuing involvement such as servicing responsibilities, generally a legal opinion is obtained as to whether the transfer results in a "true sale" by law. In order to conclude whether or not a variable interest entity is required to be consolidated, careful consideration will be given to the Company's continuing involvement with the variable interest entity. In circumstances where the Company has both the power to direct the activities of the entity that most significantly impact the entity's performance and the obligation to absorb losses or the right to receive benefits of the entity that could be significant, the Company would conclude that it would consolidate the entity, which would also preclude the Company from recording an accounting sale on the transaction. In the case of a consolidated variable interest entity, the accounting is similar to a secured financing, (i.e., the Company continues to carry the loans and records the related securitized debt on the balance sheet). 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 at estimated fair value of the collateral, less estimated costs to sell. Losses arising from the initial acquisition of such properties are charged against the allowance for loan losses at the time of transfer. Subsequent valuation adjustments to reflect fair 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. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional nonrecurring fair value disclosures. Loans with Government Guarantees The Company originates government guaranteed loans which are pooled and sold as Ginnie Mae mortgage backed securities. Pursuant to Ginnie Mae servicing guidelines, the Company has the unilateral right to repurchase certain delinquent loans (loans past due 90 days or more) securitized in Ginnie Mae pools, if the loans meet defined delinquent loan criteria. As a result of this unilateral right, once the delinquency criteria have been met, and regardless of whether the repurchase option has been exercised, the Company accounts for the loans as if they had been repurchased. The Company recognizes the loans as loans with government guarantees on the Consolidated Statements of Financial Condition and also recognizes a corresponding liability for a corresponding amount recorded in other liabilities on the Consolidated Statement of Financial Condition. If the loan is repurchased, the liability is settled and the loan with government guarantee remains. Once repurchased, the Company may collect losses through a claims process with the FHA, as an approved lender. The Company adopted ASU Update No. 2014-14, Receivables - Troubled Debt Restructuring by Creditors (Subtopic 310-40) in the first quarter 2015 at which time repossessed assets and the associated claims were recorded separately from the associated loans. At December 31, 2015, repossessed assets and the associated claims were recorded in other assets and at December 31, 2014 repossessed assets and the associated claims were included in loans with government guarantees. Federal Home Loan Bank Stock The Bank owns stock in the Federal Home Loan Bank of Indianapolis. No market quotes exist for the stock. The stock is redeemable at par and is carried at cost. The investment is required to permit the Bank to obtain membership in and to borrow from the Federal Home Loan Bank. 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. Repair and maintenance costs and software expenditures that are considered general, administrative, or of a maintenance nature are expensed as incurred. Mortgage Servicing Rights ("MSRs") The Company purchases and originates mortgage loans for sale to the secondary market and sells the loans on either a servicing-retained or servicing-released basis. For servicing retained sales, an MSR is created at the time of sale which is recorded at fair value. The Company uses an option-adjusted spread valuation utilizing an internal valuation 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 experts to assess the reasonableness of the fair value calculated by its internal valuation model. Changes in fair value of the Company's mortgage servicing rights are reported on the Consolidated Statements of Operations in "net return on mortgage servicing". See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures. The Company periodically sells portions of its MSRs, and may simultaneously enter into an agreement to subservice the residential mortgage loans sold, 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. As MSRs are not considered financial assets for accounting purposes, the transfer of an MSR asset qualifies as a sale based on a risks and rewards approach. Servicing Fee Income Servicing fee income, which is included on the Consolidated Statements of Operations as loan administration income, is recorded for fees earned, net of third party subservicing costs for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees are also included on the Consolidated Statements of Operations as net return on mortgage servicing asset. Subservicing fee income is recorded for fees earned, net of third party subservicing costs, for loans subserviced. Contractual subservicing fees including late fees and other ancillary income are included within loan administration income on the Consolidated Statements of Operations. Financial Instruments and Derivatives The Company enters into derivative financial instruments to manage interest rate risk and to facilitate asset/liability management. The Company generally uses derivatives to manage its pipeline of loans held-for-sale with forward commitments to sell Fannie Mae or Freddie Mac or Ginnie Mae mortgage backed securities. Further, the Company occasionally enters into swap agreements to manage the cash flows on certain liabilities. For all derivatives outside of those noted below, the Company does not elect to apply or does not qualify for hedge accounting and therefore accounts for the derivatives as economic undesignated derivatives. Changes in the fair value of the derivatives and realized gains and losses are recognized immediately in total noninterest income on the Consolidated Statements of Operations. The Company uses interest rate swaps to hedge the forecasted cash flows from its underlying variable-rate Federal Home Loan Bank ("FHLB") advances in a qualifying cash flow hedge accounting relationship. 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 along with the debt interest expense in the same period in which the identified hedge transaction is recognized in earnings. Cash flows and the impact on income related to designated hedges is reported in the same category as the underlying hedged item. Derivatives that are designated in hedging relationships are evaluated for effectiveness using regression analysis at the time they are designated and throughout the hedge period. U.S. Treasury futures and U.S. Treasury options are actively traded and their fair values are obtained from an exchange. Forward loan sale commitments and interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable. Rate lock commitments are valued using internal models with significant unobservable market parameters. The Company assesses the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions at each period end. As of December 31, 2015 and 2014 , the Company determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. The Company writes and purchases interest rate swaps for customer-initiated trading derivatives which are used primarily to provide derivative products to customers enabling them to manage their interest rate risk. In the event that a customer requests early termination of a derivative transaction, a termination confirmation and transaction summary will be completed. If the market rate is higher at termination than at trade inception, the customer will receive a payment from the Company. In turn, the Company will receive that payment from the dealer due to the termination of the hedge. Conversely, if the market rate is lower at termination than at trade inception, the Company will be due a payment from the customer. In turn, the Company will owe that payment to the dealer due to the termination of the hedge. The Company also enters into various derivative agreements with customers in the form of interest-rate lock commitments. As an intermediary, the Company generally maintains a portfolio of matched offsetting derivative agreements. The Company takes into account the impact of bilateral collateral and master netting agreements that allow all derivative contracts held to settle with a single counterparty on a net basis, and to offset the net derivative position with the related collateral when recognizing derivative assets and liabilities. For the rate lock commitments, the gains and losses recorded in earnings are included in "net gain on loan sales" on the Consolidated Statements of Operations. The Company recognizes all derivatives as either other assets or other liabilities in the Consolidated Statements of Financial Condition at their fair value. Additional information regarding the accounting for derivatives is provided in Note 11 and additional recurring fair value disclosures in Note 24 of the Notes to the Consolidated Financial Statements, herein. 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. The Company evaluates its deferred tax assets to determine if, based on all available evidence, it is more likely than not that the deferred tax assets will be realized and establishes a valuation allowance when they are not. 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. Representation and Warranty Reserve When the Company sells mortgage loans into the secondary mortgage market, it makes 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. Typically, these representations and warranties are in place for the life of the loan. If a defect in the origination process is identified, the Company 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 the Company's 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 the Company’s most recent data including loss severity on repurchased and indemnified loans, and repurchase requests, among other factors. Changes to the Company’s previous estimates are recorded in the representation and warranty provision 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 $9 million , $10 million , and $9 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. Stock-Based Compensation All share-based payments to employees, including grants of employee stock options and restricted stock units, are recognized as expense 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 v

During the year ended December 31, 2013 , the Company sold $170 million of trading securities, which resulted in a realized gain of less than $1 million . Available-for-Sale The Company purchased $1.1 billion of investment securities, all of which were U.S. government sponsored agencies, comprised of mortgage-backed securities and collateralized mortgage obligations and $14 million of municipal obligations during the year ended December 31, 2015 . During the year ended December 31, 2014 the Company purchased $1.2 billion of investment securities, all of which were U.S. government sponsored agencies, comprised of mortgage-backed securities and collateralized mortgage obligations, compared to $1.1 billion of investment securities issued by U.S. government sponsored agencies and $20 million of municipal obligations during the year ended December 31, 2013 . Gains (losses) on the sales of investment securities available-for-sale are reported in other noninterest income in the Consolidated Statements of Operations. During the year ended December 31, 2015 , there were $170 million in sales of U.S. government sponsored agency securities, which resulted in a gain of $3 million . During the year ended December 31, 2014 , the Company sold $414 million of U.S. government sponsored agency securities, which resulted in a gain of $4 million , compared to $39 million of U.S. government sponsored agencies, which resulted in a gain of $1 million during the year ended December 31, 2013 . Held-to-Maturity During the year ended December 31, 2015 , the Company transferred $1.1 billion of available-for-sale securities to held-to-maturity securities including a premium of $8 million , reflecting the Company’s intent and ability to hold those securities to maturity. Transfers of investment securities into the held-to-maturity category from the available-for-sale category are accounted for at fair value at the date of transfer. 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. The Company did not have any investment securities classified as held-to-maturity at December 31, 2014 . The Company purchased $217 million of held-to-maturity securities, which included agency-collateralized mortgage obligations during the year ended December 31, 2015 . There were no purchases during the years ended December 31, 2014 and December 31, 2013 . The Company had no sales in held-to-maturity securities during the years ending December 31, 2015 , 2014 and 2013 , respectively. The following table summarizes by duration the unrealized loss positions on investment securities. Unrealized Loss Position with Duration 12 Months and Over Unrealized Loss Position with Duration Under 12 Months Fair Value Number of Securities Unrealized Loss Fair Value Number of Securities Unrealized Loss (Dollars in millions) December 31, 2015 Available-for-sale securities Agency - Commercial $ 482 27 $ (3 ) $ — — $ — Agency - Residential $ 224 15 $ (2 ) $ 8 2 $ — Held-to-maturity securities Agency - Commercial $ 471 27 $ (2 ) $ — — $ — Agency - Residential $ 547 50 $ (4 ) $ — — $ — December 31, 2014 Available-for-sale securities Agency - Commercial $ 53 6 $ — $ 305 21 $ (2 ) Agency - Residential $ 98 10 $ (1 ) $ 37 4 $ — December 31, 2013 Available-for-sale securities Agency - Commercial $ — — $ — $ 326 19 $ (4 ) Agency - Residential $ — — $ — $ 500 44 $ (6 ) Credit related declines in the available-for-sale and held-to-maturity securities are classified as other-than temporary impairments ("OTTI") and are reported as a separate component of noninterest income within the Consolidated Statement of Operations. If an impaired investment security is considered to be other than temporary if (1) the Company intends to sell the security; (2) it is more likely than not the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not sufficient to recover all contractually required principal and interest payments. Management evaluates its securities portfolio each quarter to determine if any security is considered to be other than temporarily impaired. In making this evaluation, management considers its ability and intent to hold securities to recover current market losses. During the years ended December 31, 2015 and December 31, 2014 , the Company had no other-than-temporary impairments ("OTTI"). During the year ended December 31, 2013 , the Company recognized $9 million of OTTI on the FSTAR 2006-1 mortgage securitization, which was subsequently dissolved at June 30, 2013. The Company recognized a tax benefit of $6 million during the second quarter 2013 representing the recognition of the residual tax effect associated with the previously unrealized losses on the mortgage securitization recorded in other comprehensive income (loss). At December 31, 2013 , the Company had no OTTI. The following table shows the OTTI roll forward.

Loans with Government Guarantees	Loans with Government Guarantees The majority of loans with government guarantees continue to be insured or guaranteed by the Federal Housing Administration ("FHA"). These 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. At December 31, 2015 and December 31, 2014 , respectively, loans with government guarantees totaled $485 million and $1.1 billion . The Company adopted ASU Update No. 2014-14, Receivables - Troubled Debt Restructuring by Creditors (Subtopic 310-40) in the first quarter 2015 at which time repossessed assets and the associated claims were recorded separately from the associated loans. At December 31, 2015 , repossessed assets and the associated claims recorded in other assets totaled $210 million and at December 31, 2014 repossessed assets and the associated claims were $373 million included in loans with government guarantees.

Descriptions of the Company's 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 the Company will sustain some loss if the deficiencies are not corrected. For HELOC loans and other consumer loans, the Company evaluates credit quality based on the aging and status of payment activity and includes all nonperforming loans. Doubtful . An asset classified as doubtful has all the weaknesses inherent in one classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. A doubtful asset has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral, and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Because of high probability of loss, non-accrual accounting treatment is required for doubtful assets. Loss. An asset classified as loss is considered uncollectible and of such little value that the continuance as 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, the Company assigns 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
	Dec. 31, 2015
Transfers and Servicing [Abstract]
Mortgage Servicing Rights	Mortgage Servicing Rights The Company has investments in mortgage servicing rights ("MSRs") resulting from the sale of loans to the secondary market and retaining the servicing. The primary risk associated with MSRs is the potential change in 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. The Company also utilizes 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. The Company's portfolio of MSRs is highly sensitive to movements in interest rates. There is also a risk of valuation decline due to higher than expected increases in default rates, which the Company does not believe can be effectively hedged. See Note 11 of the Notes to the Consolidated Financial Statements, herein, for additional information regarding the instruments utilized to hedge the risks of MSRs. Changes in the carrying value of residential first mortgage MSRs, accounted for at fair value, were as follows. For the Years Ended December 31, 2015 2014 2013 (Dollars in millions) Balance at beginning of period $ 258 $ 285 $ 711 Additions from loans sold with servicing retained 260 272 402 Reductions from sales (176 ) (232 ) (835 ) Changes due to (1) Decrease in MSR value due to pay-offs and pay-downs (43 ) (31 ) (99 ) Changes in estimates of fair value (2) (3 ) (36 ) 106 Fair value of MSRs at end of period $ 296 $ 258 $ 285 (1) Changes in fair value are included within net return on mortgage servicing asset on the Consolidated Statements of Operations.

(3) Changes in the derivatives utilized as economic hedges to offset changes in fair value of the MSRs. Contractual servicing and subservicing fees . Contractual servicing and subservicing fees, including late fees and other ancillary income are presented below. Contractual servicing fees are included within net return on mortgage servicing asset on the Consolidated Statements of Operations. Contractual subservicing fees including late fees and other ancillary income are included within loan administration income on the Consolidated Statements of Operations. Subservicing fee income is recorded for fees earned, net of third party subservicing costs, for loans subserviced. The following table summarizes income and fees associated with subserviced mortgage loans. For the Years Ended December 31, 2015 2014 2013 (Dollars in millions) Income (expenses) on mortgage loans subserviced Servicing fees, ancillary income and late fees (1) $ 33 $ 28 $ 17 Other servicing charges (7 ) (4 ) (11 ) Total income on mortgage loans subserviced, included in loan administration $ 26 $ 24 $ 6 (1) Servicing fees are recorded on the accrual basis. Ancillary income and late fees are recorded on cash basis. The following table summarizes the hypothetical effect on the fair value of servicing rights carried at fair value using adverse changes of 10 percent and 20 percen t to the weighted-average of certain significant assumptions used in valuing these assets. December 31, 2015 December 31, 2014 Fair value due to Fair value due to Actual 10% adverse change 20% adverse change Actual 10% adverse change 20% adverse change (Dollars in millions) Option adjusted spread 8.24 % $ 287 $ 279 8.88 % $ 250 $ 243 Constant prepayment rate 12.63 % 285 275 14.98 % 253 245 Weighted average cost to service per loan $ 71.86 292 288 $ 74.49 258 255 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 impacting the fair value constant on the fair value of the servicing rights. In practice, a change in one assumption generally impacts other assumptions, which may either magnify or counteract the effect of the change.

Derivative Financial Instrument

Derivative Financial Instruments	12 Months Ended

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. The Company is exposed to non-performance risk by the counterparties to its various derivative financial instruments. The Company believes that the non-performance risk inherent in all its derivative contracts is minimal based on credit standards and the collateral provisions of the derivative agreements. A majority of the Company’s derivatives are centrally cleared through a Central Counterparty Clearing House or consist of residential mortgage interest rate lock commitments further limiting non-performance risk. Derivatives not designated as hedging instruments: The Company maintains 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. The Company also enters 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 loans held-for-sale 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: The Company uses interest rate swaps to hedge the forecasted cash flows from its underlying variable-rate Federal Home Loan Bank (FHLB) advances in a qualifying cash flow hedge accounting relationship. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense in the same period in which the hedge transaction is recognized in earnings. At December 31, 2015 , the Company had $3 million (net-of-tax) of unrealized losses on derivatives classified as cash flow hedges recorded in other comprehensive income (loss), compared to zero at December 31, 2014 . The estimated amount to be reclassified from other comprehensive income into earnings during the next 12 months represents $7 million of losses (net-of-tax). Derivatives that are designated in hedging relationships are assessed for effectiveness using regression analysis at the time they are designated and throughout the hedge period. All cash flow hedges were highly effective as of December 31, 2015 .

Therefore, the May Investor Warrants are classified as "other liabilities" on the Consolidated Statements of Financial Condition and are measured at fair value. Warrant liabilities are valued using a binomial lattice 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, 2015 and 2014 , the liability from May Investors Warrants amounted to $8 million and $6 million , respectively. Warrant liabilities are reported in "other liabilities" on the Consolidated Statements of Financial Condition. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures. TARP Warrant A warrant associated with Series C fixed rate cumulative non-convertible perpetual preferred stock ("Series C Preferred Stock") to purchase up to 645,138 shares of Common Stock remains outstanding through December 2019 at an exercise price of $62.00 per share.

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 the earnings of the Company. The following table sets forth the computation of basic and diluted earnings (loss) per share of common stock. For the Years Ended December 31, 2015 2014 2013 (In millions, except share data) Net income (loss) $ 158 $ (69 ) $ 267 Less: preferred stock dividend/accretion — (1 ) (6 ) Net income (loss) from continuing operations 158 (70 ) 261 Deferred cumulative preferred stock dividends (30 ) (26 ) (14 ) Net income (loss) applicable to Common Stockholders $ 128 $ (96 ) $ 247 Weighted Average Shares Weighted average common shares outstanding 56,426,977 56,246,528 56,063,282 Effect of dilutive securities May Investor Warrants (1) 305,484 — 237,412 Stock-based awards 432,062 — 217,487 Weighted average diluted common shares 57,164,523 56,246,528 56,518,181 Earnings (loss) per common share Basic earnings (loss) per common share $ 2.27 $ (1.72 ) $ 4.40 Effect of dilutive securities May Investor Warrants (0.01 ) — (0.02 ) Stock-based awards (0.02 ) — (0.01 ) Diluted earnings (loss) per common share $ 2.24 $ (1.72 ) $ 4.37 (1) Includes the May Warrants at an exercise price of $10.00 per share and a fair value of $8 million and $11 million at December 31, 2015 and 2013 , respectively. The December 31, 2014 diluted loss per share calculation excludes all common stock equivalents, including 263,267 pertaining to stock based awards and 306,310 pertaining to warrants, respectively. The inclusion of these securities would be anti-dilutive. Under the terms of the Series C Preferred Stock the Company may defer dividend payments. The Company elected to defer dividend payments beginning with the February 2012 dividend. Although not included in quarterly net income (loss) from continuing operations, the deferral still impacts net income (loss) applicable to common stock for the purpose of calculating earnings per share, as shown above. The cumulative amount in arrears as of December 31, 2015 is $86 million .

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, 2015 and 2014 , the Company had federal net operating loss carry forwards of $660 million and $743 million , respectively. These carry forwards, if unused, expire in calendar years 2028 through 2033 . 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 the Company's new operating loss carry forwards that existed at that time. At December 31, 2015 the Company had $154 million of net operating loss carry forwards subject to certain annual use limitations which expire in calendar years 2028 through 2029 . The Company regularly evaluates 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. The Company considers the following possible sources of taxable income when assessing the realization of deferred tax assets: • future reversals of existing taxable temporary differences; • future taxable income exclusive of reversing temporary differences and carryforwards; • taxable income in prior carryback years; and • tax planning strategies. The assessment regarding whether a valuation allowance is required or should be adjusted also considers all available positive and negative evidence factors, including but not limited to: • nature, frequency and severity of recent losses; • duration of statutory carryforward periods; • historical experience with tax attributes expiring unused; and • near- and medium-term financial outlook. As indicated by applicable accounting standards, it is inherently difficult to conclude a valuation allowance is not required when there is significant objective and verifiable negative evidence, such as cumulative losses in recent years. The Company utilizes a rolling three years of actual and current year anticipated results as the primary measure of cumulative losses. When evaluating whether the Company has overcome the significant negative evidence attributable to actual cumulative losses in recent years, the Company adjusted those losses for items that the Company believes are not indicative of its ability to generate taxable income in future years. The Company reflects adjusted cumulative income after applying those items that are not indicative of its ability to generate taxable income in future years. The Company considers this objectively verifiable evidence that its current earnings model is capable of generating future taxable income sufficient to utilize substantially all of the net operating loss carryforwards as of each period end. The Company believes that this evidence is sufficient to overcome the unadjusted cumulative losses in recent years . Upon considering all of the available positive and negative evidence, and the extent to which that evidence was objectively verifiable, the Company determined that the positive evidence outweighed the negative evidence and the deferred tax assets are more likely than not realizable. The Company released its valuation allowance in the fourth quarter of 2013 and continued to conclude that its Federal deferred tax assets are more likely than not realizable as of December 31, 2015 and 2014. The Company had a total state deferred tax asset before valuation allowance of $33 million and total state net operating loss carryforwards of $621 million at December 31, 2015 . In connection with its ongoing assessment of deferred taxes, the Company analyzed each state net operating loss separately 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 for state net operating losses to the amount which is more likely than not to be realized. At December 31, 2015 , the state deferred tax assets which will more likely than not be realized, was $11 million and we have maintained a valuation allowance of $22 million due to state loss carryover limitations. The Company will continue to regularly assess the realizability of its deferred tax assets. Changes in earnings performance and future earnings projections, among other factors, may cause the Company to adjust its valuation allowance, which will impact the Company's income tax expense in the period it determines that these factors have changes. The Company’s 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, 2015 , the Internal Revenue Service had completed an examination of the Company through the taxable year ended December 31, 2011 . The years open to examination by state and local government authorities vary by jurisdiction. The total amounts of unrecognized tax benefits for the years ended December 31, 2015 , 2014 and 2013 was $1 million for each year. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. For the years ended December 31, 2015 , 2014 and 2013 , the Company 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 T he Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by regulators that could have a material effect on the Consolidated Financial Statements. On January 1, 2015, the Basel III rules became effective and include transition provisions through 2018. To be categorized as "well-capitalized," the Company and the Bank must maintain minimum tangible capital, Tier 1 capital, common equity Tier 1, and total capital ratios as set forth in the table below. The Company and the Bank are considered "well-capitalized" at both December 31, 2015 and December 31, 2014 . There have been no conditions or events that management believes have changed the Company's or the Bank’s category. The following tables show the regulatory capital ratios as of the dates indicated.

(1) On January 1, 2015, the Basel III rules became effective, subject to transition provisions primarily related to regulatory deductions and adjustments impacting common equity Tier 1 capital and Tier 1 capital. The Company and the Bank reported under Basel I (which included the Market Risk Final Rules) at December 31, 2014. Consent Orders Effective October 23, 2012, the Bank's board of directors executed a Stipulation and Consent (the "Stipulation"), accepting the issuance of a Consent Order (the "Consent Order") by the OCC. The Consent Order replaces the supervisory agreement entered into between the Bank and the Office of Thrift Supervision (the "OTS") on January 27, 2010. Under the Consent Order, the Bank is required to adopt or review and revise various plans, policies and procedures. Specifically, under the terms of the Consent Order, the Bank's board of directors has agreed to, among other things, which include but is not limited to the following: • Review, revise, and forward to the OCC a written capital plan for the Bank covering at least a three -year period and establishing projections for the Bank's overall risk profile, earnings performance, growth expectations, balance sheet mix, off-balance sheet activities, liability and funding structure, capital and liquidity adequacy, as well as a contingency capital funding process and plan that identifies alternative capital sources should the primary sources not be available; • Adopt and forward to the OCC a comprehensive written liquidity risk management policy that systematically requires the Bank to reduce liquidity risk; and • Develop, adopt, and forward to the OCC a written enterprise risk management program that is designed to ensure that the Bank effectively identifies, monitors, and controls its enterprise-wide risks, including by developing risk limits for each line of business. Each of the plans, policies and procedures referenced above in the Consent Order, as well as any subsequent amendments or changes thereto, must be submitted to the OCC for a determination that the OCC has no supervisory objection to them. Upon receiving a determination of no supervisory objection from the OCC, the Bank must implement and adhere to the respective plan, policy or procedure. The foregoing summary of the Consent Order does not purport to be a complete description of all of the terms of the Consent Order, and is qualified in its entirety by reference to the copy of the Consent Order filed with the SEC as an exhibit to the Company's Current Report on Form 8-K filed on October 24, 2012. The Bank intends to address the banking issues identified by the OCC in the manner required for compliance by the OCC. There can be no assurance that the OCC will not provide substantive comments on the capital plan or other submissions that the Bank makes pursuant to the Consent Order that will have a material impact on the Company. The Company believes that the actions taken, or to be taken, to address the banking issues set forth in the Consent Order should, over time, improve its enterprise risk management practices and risk profile. 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. The failure to comply with the Supervisory Agreement could result in the initiation of further enforcement action by the Federal Reserve, including the imposition of further operating restrictions, and could result in additional enforcement actions against the Company. 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. 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. 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 capital framework under the Basel III final rule replaces the regulatory capital rules for all banks, savings associations and U.S. bank holding companies with greater than $500 million in total assets, and all savings and loan holding companies. Beginning January 1, 2015 the final rules required 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, and Tier 1 capital of at least 4 percent of adjusted quarterly average assets. In addition, the final rule implemented a new common equity Tier 1 minimum capital requirement of at least 4.5 percent of risk-weighted assets. In addition, the new regulations subject a banking organization to certain limitations on capital distributions and discretionary bonus payments to executive officers if the organization did not maintain a capital conservation buffer of common equity tier 1 capital in an amount greater than 2.5 percent of its total risk-weighted assets. The effect of the capital conservation buffer is to increase the minimum common equity tier 1 capital ratio to 7.0 percent , the minimum tier 1 risk-based capital ratio to 8.5 percent and the minimum total risk-based capital ratio to 10.5 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 issued on or after May 19, 2010. Among the hybrid debt and equity securities included in this prohibition are trust preferred securities. 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 The Company and its 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. The Company assesses the liabilities and loss contingencies in connection with such pending or threatened legal and regulatory proceedings on at least a quarterly basis and establishes accruals when the Company believes 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, including the matters described below, will be material to the Company’s financial statements, or that the ultimate outcome of these actions will have a material adverse effect on its financial condition, results of operations or cash flows. DOJ litigation settlement The Company elected the fair value option to account for the liability representing the obligation to make future additional payments under the DOJ litigation settlement. The executed settlement agreement with the DOJ establishes a legally enforceable contract with a stipulated payment plan that meets the definition of a financial liability. As of December 31, 2015 the remaining future payments totaled $118 million for which the Company used a discounted cash flow model to estimate the current fair value. The model utilizes estimates including the Company's forecasts of net income, balance sheet and capital levels and considers multiple scenarios and possible outcomes as a result of the uncertainty inherent in those inputs which impact the estimated timing of the additional payments. These scenarios are probability weighted and consider the view of a market participant to estimate the fair value of the liability. The fair value of the DOJ litigation settlement liability was $84 million and $82 million using a discount rate of 7.2 percent and 8.7 percent at December 31, 2015 and 2014 respectively. At both December 31, 2015 and December 31, 2014 , excluding the fair value liability relating to the DOJ litigation settlement, the Company's total accrual for contingent liabilities was $2 million and $4 million , respectively. Commitments A summary of the contractual amount of significant commitments is as follows. December 31, 2015 2014 (Dollars in millions) Commitments to extend credit Mortgage loans interest-rate lock commitments $ 3,792 $ 2,172 HELOC commitments 150 88 Other consumer commitments 22 7 Warehouse loan commitments 871 827 Standby and commercial letters of credit 13 10 Commercial and industrial commitments 151 276 Other commercial commitments 497 169 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. The Company evaluates each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company, upon extension of credit is based on management's credit evaluation of the counterparties. The Company enters into mortgage interest-rate lock commitments with its customers. These commitments are considered to be derivative instruments and changes in the fair value of these commitments are recorded in the Consolidated Statements of Financial Condition in other assets. Further discussion on derivative instruments is included in Note 11 of the Notes to the Consolidated Financial Statements, herein. The Company has unfunded commitments under its contractual arrangement with the HELOC loans. 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 the Company to cancel the commitment due to deterioration in the borrowers’ creditworthiness. Other consumer commitments are conditional commitments issued to accommodate the financial needs of customers. The commitments are under various terms to lend funds to consumers, which include revolving credit agreements, term loan commitments and short-term borrowing agreements. Warehouse loan commitments are lines of credit provided to mortgage originators to fund loans they originate and then sell. The proceeds of the sale of the loan is used to repay the draw on the line used to fund the loan. Standby and commercial letters of credit are 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 are 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. These instruments involve, to varying degrees, elements of credit and interest rate risk beyond the amount recognized on the Consolidated Statements of Financial Condition. The Company's 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. The Company utilizes the same credit policies in making commitments and conditional obligations as it does 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 Company maintains a reserve for letters of credit, which represents the estimate for 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 balances of $2 million and $1 million for December 31, 2015 and 2014 , respectively, are reflected in other liabilities on the Consolidated Statements of Operations.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company utilizes 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, the Company uses present value techniques and other valuation methods to estimate the fair values of its 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, the Company's 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 the Company 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 the Company's own assumptions about the assumptions that market participants would use in pricing and 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, 2015 and 2014 , by caption on the Consolidated Statements of Financial Condition and by the valuation hierarchy (as described above).

The Company transferred $4 million of municipal obligation to Level 3 from Level 2 in the valuation hierarchy during the year ended December 31, 2014 . 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 Company had no other transfers during the year ended December 31, 2014 . The Company had no transfers of assets or liabilities recorded at fair value between fair value levels during the year ended December 31, 2013 . The Company utilized US Treasury future, forward agency and loan sales and interest rate swaps to manage the risk associated with mortgage servicing rights and rate lock commitments. The assets and/or liabilities transferred are valued at the end of the period.

(2) Refer to Note 1 and Note 23 o for a further discussion of the fair value of the DOJ litigation settlement 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. Our HELOC loans 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 HELOAN. 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 HELOC portfolio contain FICO scores with a minimum of 446 , maximum of 818 , and a weighted average of 681 . For the HELOC loans, increases (decreases) in the discount rate, in isolation, would lower (higher) the fair value measurement and increases (decreases) in the volume of loans expected to default in isolation, would lower (higher) the fair value measurement. For the HELOC loan related debt carried at fair value in 2014, increases (decreases) in the discount rate in isolation would result in a lower (higher) fair value measurement; increases (decreases) in prepayment rates (based on three month historical average) in isolation results in a shorter (longer) weighted average life and ultimately a higher (lower) 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 during the years ended December 31, 2015 , 2014 and 2013 were as follows. For the Years Ended December 31, 2015 2014 2013 Weighted-average life (in years) 7.9 7.8 6.1 Weighted-average constant prepayment rate 11.3 % 12.3 % 13.8 % Weighted-average discount rate 10.9 % 11.7 % 8.5 % The key economic assumptions reflected in the overall fair value of the MSRs were as follows. December 31, 2015 2014 2013 Weighted-average life (in years) 7.3 6.6 7.3 Weighted-average constant prepayment rate 12.6 % 15.0 % 11.9 % Weighted-average discount rate 10.2 % 10.9 % 10.2 % 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 the Company's 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. The significant unobservable inputs used in the fair value measurement of the DOJ litigation settlement are future balance sheet and growth rate projections for overall discount rate, including asset growth, MSR growth, peer group return on assets and return on assets improvement. The current assumptions are based on management's approved, strategic performance targets beyond the current strategic modeling horizon (2015). Significant increases (decreases) in the discount rate in isolation could result in a marginally higher (lower) fair value measurement. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The Company also has 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.

(3) The Company recorded $84 million , $49 million and $155 million in fair value losses on impaired loans held-for-investment for which the Company did not elect the fair value option (included in provision for loan losses on the Consolidated Statements of Operations) during the years ended December 31, 2015 , 2014 and 2013 , respectively. (4) The Company recorded $2 million , $4 million and $10 million in losses related to write downs of repossessed assets based on the estimated fair value of the specific assets, and recognized net losses of $2 million , $5 million and $26 million on sales of repossessed assets (both write downs and net gains/losses are included in assets resolution expense on the Consolidated Statements of Operations) during the years ended December 31, 2015 , 2014 and 2013 , respectively.

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 Federal Home Loan Bank stock. The stock is bought and sold at par by the Federal Home Loan Bank. 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 The Company 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 loans held-for-sale 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 value option has been elected.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company’s operations are conducted through four operating segments: Mortgage Originations, Mortgage Servicing, Community Banking 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. 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 sub-services mortgage loans, on a fee basis, for others. Also, the Mortgage Servicing segment services, on a fee basis, residential mortgages held-for-investment by the Community Banking segment and mortgage servicing rights held by the Other 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 Community Banking segment originates loans, provides deposits and fee based services to consumer, business, and mortgage lending customers through its Branch Banking, Business, and Commercial Banking, Government Banking, Warehouse Lending and Held-for-Investment Portfolio groups. Products offered through these teams include checking accounts, savings accounts, money market accounts, certificates of deposit, other services, consumer loans, commercial 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 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, interest rate risk management and MSR asset valuation, certain derivative and sales into the secondary market. 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 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation and Basis of Presentation	Consolidation and Basis of Presentation The Consolidated Financial Statements include our accounts and accounts of all variable interest entities ("VIEs") for which we are the primary beneficiary. The accounting and financial reporting policies of Flagstar and its subsidiaries conform to accounting principles generally accepted in the United States ("GAAP"). 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 amounts due from correspondent banks and the Federal Reserve Bank. 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 Investment securities classified as trading are recorded at fair value, with unrealized and realized gains or losses included as a component of "other noninterest income" in the Consolidated Statements of Operations. The Company measures securities classified as available-for-sale at fair value, with unrealized gains and losses, net of tax, included in "other comprehensive income (loss)" in stockholders’ equity. The Company recognizes realized gains and losses on available-for-sale 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 are obtained through independent third parties from pricing services which the Company compares to independent pricing sources on a quarterly basis. See Note 2 and Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional information on recurring fair value and investment security disclosures. Investment securities held-to-maturity 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 held-to-maturity category from the available-for-sale 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. The Company evaluates available-for-sale and held-to-maturity investment securities for other-than-temporary impairment ("OTTI") 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 the Company (1) has 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 in "net impairment losses" in the Consolidated Statements of Operations for the amount representing the credit loss on the security and a charge is recognized in other comprehensive income (loss) related to gains (losses), reclassifications, impairments, credit loss and deferred tax. 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 using the effective interest method over the period of maturity, is included in interest income. For a discussion of valuation of securities, see Note 2 of the Notes to the Consolidated Financial Statements, herein.
Loans Held-for-Sale	Loans Held-for-Sale The Company classifies loans as held-for-sale when it originates or purchases loans that it intends to sell. The Company has elected the fair value option for the majority of its loans held-for-sale. The Company estimates 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. Loans held-for-sale 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. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures. Loans that are transferred into the held-for-sale portfolio from the held-for-investment portfolio are recorded at the lower of cost or fair value when there is an intent to sell these loans. Gains or losses recognized upon the sale of loans are determined using the specific identification method.
Loans Held-for-Investment	Loans Held-for-Investment The Company classifies loans that it has the intent and ability to hold until maturity as held-for-investment. Loans held-for-investment are reported at their outstanding principal balance adjusted for any unamortized premiums, discounts, deferred fees and costs (amortized cost). The Company recognizes interest income on held-for-investment loans using the interest method, including the amortization of any deferred cost basis adjustments; unless the Company believes that the ultimate collection of contractual principal or interest payments in full is not reasonably assured. Interest income recorded on our loans is adjusted by the amortization of net premiums, net deferred loan origination costs and the amount of negative amortization (i.e., capitalized interest) arising from our option ARM loans. Loans originally classified as held-for-sale and subsequently transferred to held-for-investment continue to be measured and reported at fair value on a recurring basis. As a result of the election of the fair value option, 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 loans held-for-sale. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures. When loans originally designated as held-for-sale or loans originally designated as held-for-investment are reclassified, 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.
Loan Modifications (Troubled Debt Restructurings)	Loan Modifications (Troubled Debt Restructurings) The Company may modify certain loans in both consumer and commercial loan portfolio segments. Troubled Debt Restructurings ("TDRs") result in those instances in which a borrower demonstrates financial difficulty and for which a concession has been granted. Concessions include reduction of interest rate, extension 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. If a loan was nonperforming prior to restructuring, these 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 begin to accrue interest. Consumer loan modifications. For consumer loan programs (e.g., residential first mortgages, second mortgages, HELOC, and other consumer), the Company enters into a modification when the borrower has indicated a hardship, including illness or death in the family or a loss of employment. Other modifications occur when it is confirmed that the borrower does not possess the financial resources necessary to continue making loan payments at the current amount, but the Company’s expectation is that payments at lower amounts can be made. The primary concession given to consumer loan borrowers includes a reduced interest rate and/or an extension of the amortization period or maturity date. Commercial loan modifications. Modifications of terms for commercial loans are based on individual facts and circumstances. Commercial loan modifications may involve a reduction of the interest rate and/or an extension of the term of the loan. The Company also engages in other loss mitigation activities with troubled borrowers, which include repayment plans, forbearance arrangements, and the capitalization of past due amounts.
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, the Company attempts 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. The Company's practices regarding past due loans are designed to both assist borrowers in meeting their contractual obligations and minimize losses incurred by the bank. The Company ceases the accrual of interest on consumer and commercial loans once they become 90 days past due, or earlier when concerns exist as to the ultimate collection of principal or interest. 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 contractual terms of the loan agreement or when any portion of principal or interest is 90 days past due. See Note 24 of the Consolidated Financial Statements, herein, for additional nonrecurring fair value disclosures. When a loan within any class is impaired, the accrual of interest income is discontinued unless 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 receipts received on nonperforming impaired loans within any class 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. Cash receipts received on accruing impaired loans within any class are applied in the same manner as accruing loans that are not considered impaired.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses represents management's estimate of probable losses in the Company's loans held-for-investment portfolio, excluding loans carried under the fair value option. The Company establishes 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 a loan when it is probable all amounts due will not be collected pursuant to the 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 the Company's 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, the Company also includes a qualitative adjustment that considers economic risks, industry and geographic concentrations and other factors not adequately captured in the Company's methodology. For both consumer and commercial loans deemed impaired, the loans are evaluated on at least a quarterly basis for impairment. The Company measures the level of impairment based on the present value of the expected future cash flows discounted at the loan’s effective interest rate, the observable market price of the loan, or the fair value of the collateral if the loan is collateral dependent, reduced by estimated disposal costs. If the fair value less the costs to sell are less than the carrying value of the loan, an impairment is recorded, otherwise no allowance is recorded. 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, whatever 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	The Company’s recognition of gain or loss on the sale of loans for which it surrenders control is accounted for as a sale to the extent that consideration received does not include a beneficial interest in the transferred assets. In the event the Company retains a beneficial interest in the transferred assets, the carrying value of the assets sold is allocated between the assets sold and the retained interests, other than the mortgage servicing rights, based on their relative fair values. Retained mortgage servicing rights are recorded at fair value. In assessing whether control has been surrendered, the Company considers (1) whether the transferee would be a consolidated affiliate, (2) the existence and extent of any continuing involvement in the transferred financial assets and (3) the impact of all arrangements or agreements made contemporaneously with or in contemplation of the transfer, even if they were not entered into at the time of transfer. 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. For certain transfers, such as in connection with complex transactions or where the Company has continuing involvement such as servicing responsibilities, generally a legal opinion is obtained as to whether the transfer results in a "true sale" by law.
Variable Interest Entities	In order to conclude whether or not a variable interest entity is required to be consolidated, careful consideration will be given to the Company's continuing involvement with the variable interest entity. In circumstances where the Company has both the power to direct the activities of the entity that most significantly impact the entity's performance and the obligation to absorb losses or the right to receive benefits of the entity that could be significant, the Company would conclude that it would consolidate the entity, which would also preclude the Company from recording an accounting sale on the transaction. In the case of a consolidated variable interest entity, the accounting is similar to a secured financing, (i.e., the Company continues to carry the loans and records the related securitized debt on the balance sheet).
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 at estimated fair value of the collateral, less estimated costs to sell. Losses arising from the initial acquisition of such properties are charged against the allowance for loan losses at the time of transfer. Subsequent valuation adjustments to reflect fair 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 The Company originates government guaranteed loans which are pooled and sold as Ginnie Mae mortgage backed securities. Pursuant to Ginnie Mae servicing guidelines, the Company has the unilateral right to repurchase certain delinquent loans (loans past due 90 days or more) securitized in Ginnie Mae pools, if the loans meet defined delinquent loan criteria. As a result of this unilateral right, once the delinquency criteria have been met, and regardless of whether the repurchase option has been exercised, the Company accounts for the loans as if they had been repurchased. The Company recognizes the loans as loans with government guarantees on the Consolidated Statements of Financial Condition and also recognizes a corresponding liability for a corresponding amount recorded in other liabilities on the Consolidated Statement of Financial Condition. If the loan is repurchased, the liability is settled and the loan with government guarantee remains. Once repurchased, the Company may collect losses through a claims process with the FHA, as an approved lender. The Company adopted ASU Update No. 2014-14, Receivables - Troubled Debt Restructuring by Creditors (Subtopic 310-40) in the first quarter 2015 at which time repossessed assets and the associated claims were recorded separately from the associated loans. At December 31, 2015, repossessed assets and the associated claims were recorded in other assets and at December 31, 2014 repossessed assets and the associated claims were included in loans with government guarantees.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock The Bank owns stock in the Federal Home Loan Bank of Indianapolis. No market quotes exist for the stock. The stock is redeemable at par and is carried at cost. The investment is required to permit the Bank to obtain membership in and to borrow from the Federal Home Loan Bank.
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. Repair and maintenance costs and software expenditures that are considered general, administrative, or of a maintenance nature are expensed as incurred.
Mortgage Servicing Rights (MSRs)	Mortgage Servicing Rights ("MSRs") The Company purchases and originates mortgage loans for sale to the secondary market and sells the loans on either a servicing-retained or servicing-released basis. For servicing retained sales, an MSR is created at the time of sale which is recorded at fair value. The Company uses an option-adjusted spread valuation utilizing an internal valuation 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 experts to assess the reasonableness of the fair value calculated by its internal valuation model. Changes in fair value of the Company's mortgage servicing rights are reported on the Consolidated Statements of Operations in "net return on mortgage servicing". See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures. The Company periodically sells portions of its MSRs, and may simultaneously enter into an agreement to subservice the residential mortgage loans sold, 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. As MSRs are not considered financial assets for accounting purposes, the transfer of an MSR asset qualifies as a sale based on a risks and rewards approach.
Servicing Fee Income	Servicing Fee Income Servicing fee income, which is included on the Consolidated Statements of Operations as loan administration income, is recorded for fees earned, net of third party subservicing costs for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Late fees and ancillary fees are also included on the Consolidated Statements of Operations as net return on mortgage servicing asset. Subservicing fee income is recorded for fees earned, net of third party subservicing costs, for loans subserviced. Contractual subservicing fees including late fees and other ancillary income are included within loan administration income on the Consolidated Statements of Operations.
Financial Instruments and Derivatives	Financial Instruments and Derivatives The Company enters into derivative financial instruments to manage interest rate risk and to facilitate asset/liability management. The Company generally uses derivatives to manage its pipeline of loans held-for-sale with forward commitments to sell Fannie Mae or Freddie Mac or Ginnie Mae mortgage backed securities. Further, the Company occasionally enters into swap agreements to manage the cash flows on certain liabilities. For all derivatives outside of those noted below, the Company does not elect to apply or does not qualify for hedge accounting and therefore accounts for the derivatives as economic undesignated derivatives. Changes in the fair value of the derivatives and realized gains and losses are recognized immediately in total noninterest income on the Consolidated Statements of Operations. The Company uses interest rate swaps to hedge the forecasted cash flows from its underlying variable-rate Federal Home Loan Bank ("FHLB") advances in a qualifying cash flow hedge accounting relationship. 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 along with the debt interest expense in the same period in which the identified hedge transaction is recognized in earnings. Cash flows and the impact on income related to designated hedges is reported in the same category as the underlying hedged item. Derivatives that are designated in hedging relationships are evaluated for effectiveness using regression analysis at the time they are designated and throughout the hedge period. U.S. Treasury futures and U.S. Treasury options are actively traded and their fair values are obtained from an exchange. Forward loan sale commitments and interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable. Rate lock commitments are valued using internal models with significant unobservable market parameters. The Company assesses the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions at each period end. As of December 31, 2015 and 2014 , the Company determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. The Company writes and purchases interest rate swaps for customer-initiated trading derivatives which are used primarily to provide derivative products to customers enabling them to manage their interest rate risk. In the event that a customer requests early termination of a derivative transaction, a termination confirmation and transaction summary will be completed. If the market rate is higher at termination than at trade inception, the customer will receive a payment from the Company. In turn, the Company will receive that payment from the dealer due to the termination of the hedge. Conversely, if the market rate is lower at termination than at trade inception, the Company will be due a payment from the customer. In turn, the Company will owe that payment to the dealer due to the termination of the hedge. The Company also enters into various derivative agreements with customers in the form of interest-rate lock commitments. As an intermediary, the Company generally maintains a portfolio of matched offsetting derivative agreements. The Company takes into account the impact of bilateral collateral and master netting agreements that allow all derivative contracts held to settle with a single counterparty on a net basis, and to offset the net derivative position with the related collateral when recognizing derivative assets and liabilities. For the rate lock commitments, the gains and losses recorded in earnings are included in "net gain on loan sales" on the Consolidated Statements of Operations. The Company recognizes all derivatives as either other assets or other liabilities in the Consolidated Statements of Financial Condition at their fair value.
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. The Company evaluates its deferred tax assets to determine if, based on all available evidence, it is more likely than not that the deferred tax assets will be realized and establishes a valuation allowance when they are not. 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.
Representation and Warranty Reserve	Representation and Warranty Reserve When the Company sells mortgage loans into the secondary mortgage market, it makes 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. Typically, these representations and warranties are in place for the life of the loan. If a defect in the origination process is identified, the Company 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 the Company's 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 the Company’s most recent data including loss severity on repurchased and indemnified loans, and repurchase requests, among other factors. Changes to the Company’s previous estimates are recorded in the representation and warranty provision 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 recognized as expense 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. The Company utilizes the weighted average assumptions in applying a Black-Scholes model to determine the fair value of employee stock options. See Note 20 of the Notes to the Consolidated Financial Statements, herein, for further discussion and details of stock-based compensation.
Department of Justice (DOJ) Litigation Settlement	Department of Justice ("DOJ") Litigation Settlement The Company elected the fair value option to account for the liability representing the obligation to make future additional payments under the DOJ litigation settlement. The executed settlement agreement with the DOJ establishes a legally enforceable contract with a stipulated payment plan that meets the definition of a financial liability. As of December 31, 2015 the remaining future payments totaled $118 million for which the Company used a discounted cash flow model to estimate the current fair value. The model utilizes estimates including the Company's forecasts of net income, balance sheet and capital levels and considers multiple scenarios and possible outcomes as a result of the uncertainty inherent in those inputs which impact the estimated timing of the additional payments. These scenarios are probability weighted and consider the view of a market participant to estimate the fair value of the liability. As of December 31, 2015 , the liability was $84 million . We value our contractual obligation to pay utilizing a discounted cash flow model that incorporates our current estimate of the most likely timing and amount of the cash flows necessary to satisfy the obligation. These cash flow estimates are reflective of our detailed financial and operating projections for the next three years, as well as more general earnings and capital assumptions for subsequent periods. The liability is included in "other liabilities" on the Consolidated Financial Statements.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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 to which the entity expects to be entitled in exchange for those goods or services. The FASB has voted to approve another year deferral of the effective date from January 1, 2017 to January 1, 2019, while allowing for early adoption as of January 1, 2018. Management is currently evaluating this guidance and does not expect this guidance to have a material impact on the Company’s Consolidated Financial Statements, but significant changes to disclosures in the Notes thereto will be required. In January 2015, the FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual items (Subtopic 225-20). ASU 2015-01 eliminates from U.S. GAAP the concept of extraordinary items, which, among other things, required an entity to segregate extraordinary items considered to be unusual and infrequent from the results of ordinary operations and show the item separately in the financial statements. The ASU is effective for the annual period beginning after December 15, 2015, though early adoption is permitted. The adoption of this guidance is not expected to have a material effect on the Company’s Consolidated Financial Statements or the Notes thereto. In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810) - Amendments to the Consolidation Analysis. Under the amended guidance all reporting entities are within the scope of Subtopic 810-10, Consolidation - Overall, including limited partnerships and similar legal entities, unless a scope exception applies. The presumption that a general partner controls a limited partnership has been eliminated. The ASU is effective for the annual period beginning after December 15, 2015, and all reporting periods thereafter. The adoption of this guidance is not expected to have a material effect on the Company’s Consolidated Financial Statements or the Notes thereto. In April 2015, the FASB issued ASU No. 2015-03, Interest-Imputation of Interest (Subtopic 835-30). The amendments will require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The ASU is effective prospectively or retrospectively for annual and interim periods beginning after December 15, 2015. The adoption of this guidance is not expected to have a material effect on the Company’s Consolidated Financial Statements or the Notes thereto. In April 2015, the FASB issued ASU No. 2015-05, Intangibles - Goodwill and Other Internal-Use Software. The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other licenses. If it does not include a software license, the customer should account for the arrangement as a service contract. The ASU is effective for the annual period beginning after December 15, 2015, and all reporting periods thereafter. The adoption of this guidance is not expected to have a material effect on the Company’s Consolidated Financial Statements or the Notes thereto. In May 2015, the FASB issued ASU No. 2015-07, Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or its equivalent). The amendments in this ASU remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient pursuant to ASC 820, Fair Value Measurement. Instead, those investments must be included as a reconciling line item so that the total fair value amount of investments in the disclosure is consistent with the amount on the balance sheet. Further, the ASU specifies that for purposes of calculating historical earnings per unit under the two-class method, the earnings (losses) of a transferred business before the date of a dropdown transaction should be allocated entirely to the general partner. ASU 2015-07 is effective for interim and annual periods beginning after December 15, 2015 and early adoption is permitted. This guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements or the Notes thereto. In July 2015, the FASB issued ASU No 2015-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965): (Part I) Fully Benefit-Responsive Investment Contracts, (Part II) Plan Investment Disclosures, (Part III) Measurement Date Practical Expedient (consensuses of the FASB Emerging Issues Task Force). Under the amendments, fully benefit-responsive investment contracts are measured, presented, and disclosed only at contract value. A plan will continue to provide disclosures that help users understand the nature and risks of fully benefit-responsive investment contracts. ASU 2015-12 is effective retrospectively for fiscal years beginning after December 15, 2015 and early adoption is permitted. This guidance is not expected to have a material impact on the Company’s Consolidated Financial Statements, but disclosures to the Notes thereto will be updated per the requirements. In September 2015, the FASB issued ASU No 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. The amendments in this ASU require that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined and in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. In addition, the amendments require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective retrospectively for fiscal years beginning after December 15, 2015 and early adoption is permitted. This guidance is not expected to have a material impact upon adoption on the Company’s Consolidated Financial Statements, but disclosures to the Notes thereto will be updated per the requirements. 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. Management is currently evaluating this guidance and does not expect this guidance to have a material impact on the Company’s Consolidated Financial Statements, if any. In February 2016, the FASB issued Update 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, 2019 and early adoption is permitted. The guidance in the Update supersedes Topic 840, Leases. Management is currently evaluating this guidance and does not expect this guidance to have a material impact on the Company’s Consolidated Financial Statements.
Fair Value Measurements	Fair Value Measurements The Company utilizes 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, the Company uses present value techniques and other valuation methods to estimate the fair values of its 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, the Company's 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 the Company 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 the Company's own assumptions about the assumptions that market participants would use in pricing and 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.

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 during the years ended December 31, 2015 , 2014 and 2013 were as follows. For the Years Ended December 31, 2015 2014 2013 Weighted-average life (in years) 7.9 7.8 6.1 Weighted-average constant prepayment rate 11.3 % 12.3 % 13.8 % Weighted-average discount rate 10.9 % 11.7 % 8.5 % The key economic assumptions reflected in the overall fair value of the MSRs were as follows. December 31, 2015 2014 2013 Weighted-average life (in years) 7.3 6.6 7.3 Weighted-average constant prepayment rate 12.6 % 15.0 % 11.9 % Weighted-average discount rate 10.2 % 10.9 % 10.2 %
