Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation, and Summary of Significant Accounting Standards	Description of Business, Basis of Presentation, and Summary of Significant Accounting Standards
	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 has 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"). 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 reporting policies of Flagstar and the methods of applying those policies that materially affect the consolidated financial statements conform with accounting principles generally accepted in the United States ("GAAP") and with general financial services industry practices. Certain prior period amounts have been reclassified to conform to the current period presentation.
	Restatement of Consolidated Statements of Cash Flows
	During the course of compiling the 2014 Consolidated Statements of Cash Flows utilizing an enhanced preparation and control process, the Company self-identified the need to reclassify the reporting of certain cash flows as coming from operating, financing and investing activities in the Consolidated Statements of Cash Flows for the year ended December 31, 2013 and each of the quarterly periods in the years 2013 and 2014. These reclassifications relate only to the presentation of certain cash flows among the cash flows from operating, financing and investing activities within the Consolidated Statements of Cash Flows and have no impact on the total cash flows for the periods impacted or beginning or ending cash balances for any of these periods.
	These reclassifications have no impact on the Consolidated Statements of Financial Condition, Consolidated Statements of Operations or the Consolidated Statements of Comprehensive Income (Loss) or on any of the Company’s key financial ratios, including liquidity measures and regulatory capital.
	On March 10, 2015, the Audit Committee of the Board of Directors of the Company, upon consultation with the Company’s independent auditors, determined that, as a result of the reclassification of the presentation of these cash flows within the Consolidated Statements of Cash Flows, the financial statements for the periods above should not be relied upon. The Company intends to file its Annual Report on Form 10-K for the year ended December 31, 2014 on March 16, 2015 with a restated Consolidated Statement of Cash Flows for the year ended December 31, 2013 and each of the quarterly periods in the years 2013 and 2014. The Company believes that the financial statements filed in that report can be relied upon.
	The primary cause of the reclassifications related to cash flows associated with our commercial loan sales that settled in the first quarter of 2013 and our nonperforming loan sales that occurred throughout 2013 and 2014, which were presented as cash flows provided from operating activities but should have been included in cash flows provided by investing activities. Prior to closing on these transactions, the Company in accordance with GAAP, transferred these assets from loans held-for-investment to loans held-for-sale. Cash Flows related to these assets are required to be classified consistent with the original balance sheet classification rather than their classification at the time of sale per ASC 230-45-12.
	The Consolidated Statement of Cash Flows for the year ended December 31, 2013, has been restated in this Form 10-K. The restated Consolidated Statements of Cash Flows revising the amounts as originally included in the Form 10-Q for the three months ended March 31, 2014 and 2013, the six months ended June 30, 2014 and 2013, and the nine months ended September 30, 2014 and 2013 are included in this Form 10-K, see Note 27 to the consolidated financial statements.
		For the Year Ended December 31, 2013
		As Reported			As Restated
		(Dollars in thousands)
	Net cash used in operating activities	$	(195,938	)	$	(1,561,388	)
	Net cash provided by investing activities	4,161,975			5,533,593
	Net cash used in financing activities	(4,638,325		)	(4,644,493		)
	Subsequent Events
	The Company has evaluated all subsequent events for potential recognition and disclosure through the filing date of this Form 10-K. In February of 2015, the Company no longer intends to hold certain TDR loans for investment purposes. As a result of this decision, the Company will transfer approximately $300.0 million (unpaid principal balance) loans currently classified as held-for-investment to loans held-for-sale in the first quarter of 2015. Management does not expect the impact of this subsequent event to have a detrimental impact in the first quarter of 2015. No other significant subsequent events have been identified.
	Use of Estimates
	The preparation of Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. Actual results could materially differ from the reported amounts due to estimates and assumptions used in a variety of areas, including but not limited to, assets and liabilities measured at fair value, other litigation accruals, the allowance for loan losses and the representation and warranty reserve.
	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.
	Cash and Cash Equivalents
	Cash on hand, cash items and amounts due from correspondent banks and the Federal Reserve Bank are included in cash and cash equivalents. Short-term investments that have a maturity at the date of acquisition of three months or less and are readily convertible to cash are considered cash equivalents.
	Investment Securities
	Trading securities are debt and equity securities that we purchase and hold but intend to sell in the near term. These assets are recorded at fair value in the Company’s Consolidated Statements of Financial Condition, with unrealized and realized gains or losses included as a component of "gain on trading securities" in the Consolidated Statements of Operations. As of December 31, 2014, the Company had no trading securities.
	The Company measures available-for-sale securities at fair value in the Consolidated Statements of Financial Condition, with unrealized gains and losses, net of tax, included in "other comprehensive income (loss)" in shareholders’ 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 "net gain on securities available-for-sale" in the Consolidated Statements of Operations.
	The fair value of available-for-sale 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 curves or other factors. The fair values are obtained through independent third parties from pricing services which the Company compares to independent pricing sources. Also included in available-for-sale securities is a municipal obligation which is valued based on similar non-rated bonds and cost approximates fair value. 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.
	The Company evaluates available-for-sale 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 cost and the Company intends to sell or it is more likely than not that the Company will be required to sell the security before recovery when a credit loss exists. At December 31, 2014, the Company had no OTTI on the available-for-sale investment securities held.
	Any security for which there has been an OTTI is written down to its estimated fair value through a charge to earnings 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. Realized securities gains and declines in value judged to be other-than-temporary representing credit losses are included in "net impairment losses" in the Consolidated Statements of Operations.
	Investment transactions are recorded on the trade date. Interest earned on 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.
	Reverse Repurchase Agreement
	The fair value of the reverse repurchase agreement is determined by cost, which approximates the fair value. The reverse repurchase agreement is guaranteed by a third party and secured by government and agency securities, which are held by a third party. In case of default, the Company would receive the collateral from the third party. The reverse repurchase agreement is included in other assets on the Consolidated Statements of Financial Condition and in Note 24 as an other investment. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional information on recurring fair value and investment security disclosures.
	Loans Held-for-Sale
	The Company classifies loans as held-for-sale when it originates or purchases loans that it intends to sell. For loans originated that the Company intends to sell, the Company has elected the fair value option. 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 is determined by discounting estimated cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures.
	Loans are transferred into the held-for-sale portfolio from the held-for-investment portfolio when there is an intent to sell these loans. Loans held-for-sale are recorded at lower of cost or fair value. Gains or losses recognized upon the sale of loans are determined using the specific identification method.
	Loans Held-for-Investment
	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 deferred and unamortized cost basis adjustments, including purchase premiums, discounts and other cost basis adjustments (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.
	As a result of the Company carrying its mortgage loans held-for-sale at fair value, any transfers of loans held-for-sale to loans held-for-investment continue to be measured and reported at fair value on a recurring basis with any changes in fair value reported in the Company’s Consolidated Statements of Operations. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures.
	Also included in loans held-for-investment are the reconsolidated VIE loans associated with the FSTAR 2005-1, 2006-1, and 2006-2 securitization trusts. The Company elected the fair value option for these assets and changes in fair value are recorded to "other noninterest income" on the Consolidated Statements of Operations. Fair value of these loans is calculated using a discounted cash flow model which utilizes observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral.
	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 rather than their current classification. As a result of the Company carrying its mortgage loans held-for-sale at fair value, any transfers of loans held-for-sale to loans held-for-investment continue to be reported at fair value with any changes in fair value reported in the Company’s Consolidated Statements of Operations.
	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, which includes reductions of interest rate, extensions of amortization period, principal and/or interest forgiveness and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral. If the 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 only 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 due. While it is the goal of management to collect on loans, a method we use is to work out a satisfactory repayment schedule or modification with a past due borrower, we 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 customarily mails several notices of past due payments to the borrower within 30 days after the due date and late charges are assessed in accordance with certain parameters. The Company's collection department makes telephone or personal contact with borrowers after loans are 30 days past due. In certain cases, the Company recommends that the borrower seek credit-counseling assistance and may grant forbearance if it is determined that the borrower is likely to correct a past due loan within a reasonable period of time. The Company ceases the accrual of interest on loans that we classify as "nonperforming" once they become 90 days past due or earlier when concerns exist as to the ultimate collection of principal or interest. Subsequently, interest is recognized as income only when it is actually collected.
	For all classes within the consumer and commercial loan portfolio, loans are placed on nonaccrual status when any portion of principal or interest is 90 days past due (or nonperforming), or earlier when the Company becomes aware of information indicating that collection of principal and interest is in doubt. When a loan is placed on nonaccrual status, the accrued interest income is reversed. Loans 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 (or nonperforming). See Note 24 of the Consolidated Financial Statements, herein, for additional non-recurring 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. 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 consumer portfolio segment includes residential first mortgages, second mortgages, HELOC and other consumer loans. The commercial portfolio segment includes commercial real estate, commercial and industrial, commercial lease financing and warehouse lending loans. 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, as of the date of the consolidated financial statements. 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).
	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. Fair value 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 if the loan is collateral dependent, reduced by estimated disposal costs.    A general allowance for losses inherent on non-impaired loans is calculated using 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 history is normally a one- to five-year rolling average updated periodically as new data becomes available. In addition to the loss history, the Company will also include a qualitative adjustment that considers economic risks, industry and geographic concentrations and other factors not adequately captured in the Company's loss methodology.
	Consumer loans.  For consumer loans that have not been identified for evaluation for impairment, the allowance for loan losses is determined based on a collective basis utilizing forecasted losses that represent management’s best estimate of inherent loss. Loans are pooled by loan types with similar risk characteristics. Historical loss models designed for each pool are utilized to develop the loss estimates based on historical losses. Management evaluates the results of the allowance for loan losses model and makes qualitative adjustments to the results of the model when it is determined that model results do not reflect all losses inherent in the loan portfolios due to changes in recent economic trends and conditions, or other relevant factors.
	For consumer 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.
	Loans secured by real estate are charged-off to the estimated fair value of the collateral when a loss is confirmed or at 120 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.
	Commercial loans. Commercial loans are assessed for estimated losses by grouping the portfolio into two segments based on underwriting and origination characteristics: legacy and new. For both segments, management observes historical losses over a relevant period. These loss estimates are adjusted as appropriate based on additional analysis of long-term average loss experience compared to previously forecasted losses, external loss data or other risks identified from current economic conditions and credit quality trends.
	The commercial loan portfolio is segmented into loans originated prior to January 1, 2011 and loans originated on or after January 1, 2011, while still retaining the segmentation by product type. The loss rates attributed to the loans originated prior to January 1, 2011 portfolio are based on historical losses of this segment. Due to the brief period of time that loans in the loans originated on or after January 1, 2011 portfolio have been outstanding, and thus the absence of a sufficient loss history for that portfolio, the Company uses loss data from a third party data aggregation firm (adjusting for the qualitative factors) as a proxy for estimating an allowance for loan losses. The Company separately identifies a population of commercial banks with similar size balance sheets (and loan portfolios) to serve as the Company's peer group. The Company utilizes this peer group's publicly available historical loss data (adjusted for the qualitative factors) as a proxy for loss rates used to determine the allowance for loan losses on the loans originated on or after January 1, 2011 commercial portfolio.
	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.
	Potential losses that may not be reflected in our model assumptions are captured through the qualitative factor adjustments discussed above. Management reviews these models on an ongoing basis and updates them as appropriate to reflect then-current industry conditions, heightened access to enhanced loss data and based upon continuous back testing of the allowance for loan losses model.
	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 whether the transferee would be a consolidated affiliate, the existence and extent of any continuing involvement in the transferred financial assets and 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 and judgment must 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 non-recurring fair value disclosures.
Loans Repurchased with Government Guarantees
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 and recognizes the loans as loans repurchased with government guarantees on the Consolidated Statements of Financial Condition and also recognizes a corresponding liability for a similar amount recorded in other liabilities on the Consolidated Statement of Financial Condition. If the loans are actually repurchased, the Company records the loans to loans repurchased with government guarantees and eliminates the corresponding liability.
Federal Home Loan Bank Stock
The Bank owns stock in the Federal Home Loan Bank of Indianapolis. No market quotes exists 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 approach 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. For the mortgage servicing rights, the gains and losses recorded in earnings are included in "net return on mortgage servicing" on the Consolidated Statements of Operations. 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 accounting model used to determine if the transfer of an MSR asset qualifies as a sale is based on a risks and rewards approach. Upon completion of MSR sales, we account for the transactions as a sale and derecognize the mortgage servicing rights from the Consolidated Statements of Financial Condition.
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 loan administration income.
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 hedges 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 hedge the cash flows on certain liabilities. The Company does not elect to apply or does not qualify for hedge accounting and therefore accounts for the derivatives as economic undesignated derivatives.
The Company recognizes all derivatives as either other assets or other liabilities in the Consolidated Statements of Financial Condition at their fair value. 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 also enters into various derivative agreements with customers desiring protection from possible adverse future fluctuations in interest rates using 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.
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, 2014 and 2013, 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 interest rate risk exposure. 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.
Additional information regarding the accounting for derivatives is provided in Note 12 and additional recurring fair value disclosures in Note 24 of the Notes to the Consolidated Financial Statements, herein.
Income Taxes
Our income tax expense, deferred tax assets and liabilities, and reserves for unrecognized tax benefits reflect management’s best assessment of estimated future taxes to be paid. Significant judgments and estimates are required in determining the income tax expense and the Company is subject to the income tax laws of the U.S., its states and municipalities.
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 records a valuation allowance to reduce its deferred tax assets to the amount it believes will be realized if, based on available evidence at the time the determination is made, it is more likely than not that some or all of the deferred tax assets will not be realized.
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 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. 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 regarding loan repurchases and indemnifications, and loss severity on repurchased and indemnified loans, among other factors. Increases to the representation and warranty reserve for current loan sales reduce the Company’s net gain on loan sales. Adjustments to the Company’s previous estimates are recorded as an increase or decrease to 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" expenses in the Consolidated Statements of Operations. Advertising expenses totaled $10.0 million, $8.9 million, and $11.9 million for the years ended December 31, 2014, 2013 and 2012, 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 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
The Company elected the fair value option to account for the liability representing the obligation to make additional payments under the DOJ Agreement. 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, 2014 the remaining future payments totaled $118.0 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, 2014, the liability was $81.6 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. At December 31, 2014, we discounted the expected cash flows using an 8.7 percent discount rate that is inclusive of the risk free rate based on the expected duration of the liability and an adjustment for nonperformance risk that represents our own credit risk. The recorded liability, at fair value, represents the present value of these estimated cash flows and is included in "other liabilities" on the Consolidated Financial Statements. We will estimate the fair value of this liability at each measurement date and record any changes in that estimate, as well as the effect of the accretion of the face amount of the liability, during the period in which these changes occur. See Note 24 of the Consolidated Financial Statements, herein, for additional information on the valuation of the litigation settlement.
Recently Issued Accounting Pronouncements
In January 2014, the FASB issued ASU No. 2014-04, "Receivables-Troubled Debt Restructurings by Creditors (Topic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure." The guidance amends the guidance in the FASB Accounting Standards Codification Topic 310-40, "Receivables - Troubled Debt Restructurings by Creditors," in efforts to reduce diversity in practice through clarifying when an in substance repossession or foreclosure occurs. Essentially, the guidance addresses when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan so that the loan should be derecognized and the real estate property recognized in the financial statements. This guidance is effective prospectively, for annual and interim periods, beginning after December 15, 2014. The Company's current policy reflects the practices discussed in this guidance. Therefore, the adoption of the guidance is not expected to have a material impact on the consolidated financial statements or the Notes thereto.
In April 2014, the FASB issued ASU No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." The amendments in this guidance will allow discontinued operations to include a component of an entity or a group of components of an entity. A disposal is required to be reported in discontinued operations if it represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. This guidance is effective prospectively, for annual and interim periods, beginning after December 15, 2014. The adoption of the guidance is not expected to have a material effect on the Company’s Consolidated Financial Statements or the Notes thereto.
In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." Under the amended guidance, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective prospectively, for annual and interim periods, beginning after December 15, 2016. 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 disclosures to the Notes thereto will be required.
In June 2014, the FASB issued ASU No. 2014-11, "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financing, and Disclosures." The amendments in this guidance requires repurchase-to-maturity transactions to be accounted for as secured borrowings. The guidance for certain transactions accounted for as a sale, repurchase agreements, securities lending transactions and repurchase-to-maturity transactions accounted for as secured borrowings is effective prospectively, for annual and interim periods, beginning after December 15, 2014. The adoption of the guidance is not expected to have a material effect on the Company’s Consolidated Financial Statements or the Notes thereto.
In August 2014, the FASB issued ASU No. 2014-13, Consolidation (Topic 810). A reporting entity that consolidates a collateralized financing entity within the scope of this update may elect to measure the financial assets and the financial liabilities of that collateralized financing entity using either the measurement alternative included in this update or Topic 820 on fair value measurement. When the measurement alternative is not elected for a consolidated collateralized financing entity within the scope of this update, the amendments clarify that (1) the fair value of the financial assets and the fair value of the financial liabilities of the consolidated collaterlized financing entity should be measured using the requirements of Topic 820 and (2) any differences in the fair value of the financial assets and the fair value of the financial liabilities of that consolidated collateralized financing entity should be reflected in earnings and attributed to the reporting entity in the consolidated statement of income (loss). The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. The Company's current policy reflects the practices discussed in this guidance. Therefore, 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 August 2014, the FASB issued ASU Update No. 2014-14, Receivables - Troubled Debt Restructuring by Creditors (Subtopic 310-40). The amendments in this update require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The adoption of this guidance is expected to move approximately $372.8 million of repossessed assets and claims receivable to other assets on the Consolidated Statements of Financial Condition.
In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40). In connection with preparing financial statements for each annual and interim reporting period, an entity's management should evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). Management's evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued (or at the date that the financial statements are available to be issued when applicable). The amendments in this update are effective for the annual period ending after December 15, 2016, and for annual periods and interim 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 January 2015, the FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual items (Subtopic 22-20). The amendments in this update eliminate the concept of extraordinary items. The amendments in this update are 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.

	At December 31, 2014 and 2013, $47.5 million and $340.0 million, respectively, of loans held-for-sale were recorded at lower of cost or fair value, based on the intent to sell the loans. Certain loans were transferred into the held-for-sale portfolio from the held-for-investment portfolio and after the transfer, any amount by which cost exceeded fair value was recorded as a valuation adjustment.

Loans Repurchased With Government Guarantees	Loans Repurchased with Government Guarantees
	At December 31, 2014, the amount of loans repurchased totaled $1.1 billion, and those loans which the Company had the unilateral right to repurchase which had not been exercised totaled $9.2 million and were classified as loans repurchased with government guarantees. At December 31, 2013, the amount of loans repurchased totaled $1.3 billion and were classified as loans repurchased with government guarantees, and those loans which the Company had the unilateral right to repurchase which had not been exercised totaled $20.8 million and were classified as loans held-for-sale.
	During the year ended December 31, 2014, the Company sold loans repurchased with government guarantees with UPB in the amount of $19.7 million, with an allowance for loan losses reserve release of $0.9 million and recognized a gain of $1.8 million.
	Substantially all of these loans continue to be insured or guaranteed by the FHA, and the Company's management believes that the reimbursement process is proceeding appropriately. These repurchased loans earn interest at a statutory rate, which varies and is based upon the 10-year U.S. Treasury note rate at the time the underlying loan becomes delinquent, which can be curtailed under certain circumstances.
	The Company has pledged certain loans repurchased with government guarantees to collateralize lines of credit and/or borrowings with the Federal Home Loan Bank of Indianapolis. At December 31, 2014 and 2013, the Company pledged $763.8 million and $787.1 million, respectively, of loans repurchased with government guarantees.

	For the years ended December 31, 2014, 2013 and 2012, the Company transferred $19.2 million, $64.3 million and $61.8 million, respectively, of loans held-for-sale to loans held-for-investment.
	The Company has pledged certain loans held-for-investment to collateralize lines of credit and/or borrowings with the Federal Reserve Bank of Chicago and the Federal Home Loan Bank of Indianapolis. At December 31, 2014 and 2013, the Company pledged $2.4 billion and $2.5 billion, respectively, of loans held-for-investment.
	The allowance for loan losses, other than those that have been identified for individual evaluation for impairment, is determined on a loan pool basis by grouping loan types with similar risk characteristics to determine the Company's best estimate of incurred losses. Management evaluates the results of the allowance for loan losses model and makes qualitative adjustments to the results of the model when it is determined that model results do not reflect all losses inherent in the loan portfolios due to changes in recent economic trends and conditions, or other relevant factors.
	For those loans not individually evaluated for impairment, management has sub-divided the commercial and consumer loans into portfolios with common risk characteristics.
	The allowance for loan losses by class of loan is summarized in the following tables.

-1	The allowance for loan losses on consumer TDR loans totaled $81.2 million and $82.3 million at December 31, 2014 and 2013, respectively.
-2	Includes $29.8 million and $31.3 million of TDR loans accounted for under the fair value option at December 31, 2014 and 2013, respectively.
TDRs returned to performing, or accrual, status totaled $6.9 million, $43.4 million and $117.7 million during the years ended December 31, 2014, 2013 and 2012, respectively, and are excluded from nonperforming loans. TDRs that have demonstrated a period of at least six months of consecutive performance under the modified terms, are returned to performing (i.e., accrual) status and are excluded from nonperforming loans. Although these TDRs have been returned to performing status, they will continue to be classified as impaired until they are repaid in full, or foreclosed and sold, and included as such in the tables within "repossessed assets." Although many of the TDRs continue to be performing, the full collection of principal and interest on some TDRs may not occur. The resulting potential incremental losses are measured through impairment analysis on all TDRs which are included in our allowance for loan losses.
Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, but may give rise to potential incremental losses. Such losses are factored into the Company's allowance for loan losses estimate. Management evaluates loans for impairment both collectively and individually depending on the risk characteristics underlying the loan and the availability of data. The Company measures impairment using the discounted cash flow method for performing TDRs and measures impairment based on collateral values for re-defaulted TDRs.
The following tables present the years ended December 31, 2014, 2013 and 2012 number of accounts, pre-modification unpaid principal balance (net of write downs), and post-modification unpaid principal balance (net of write downs) that were new modified TDRs during the years ended December 31, 2014, 2013 and 2012. In addition, the tables present the number of accounts and unpaid principal balance (net of write downs) of loans that have subsequently defaulted during the years ended December 31, 2014, 2013 and 2012 that had been modified in a TDR during the 12 months preceding each period. All TDR classes within consumer and commercial loan portfolios are considered subsequently defaulted when 90 days or greater past due.

The Company follows the guidance provided in the FFIEC’s "Uniform Retail Credit Classification and Account Management Policy" issued June 20, 2000 for Retail Credits. This policy focuses on the delinquency status, loan type, collateral protection, and other events influencing repayment, such as bankruptcy, death, and fraud, in determining the appropriate risk classification for a retail credit. The Company classifies performing retail loans that are 60 days delinquent as well as all performing retail TDRs as Watch. All non-accruing retail loans as well as retail loans 90 days or more delinquent are classified as Substandard. In cases of bankruptcy, death, or fraud, the Company will follow the FFIEC policy and classify the loans as appropriate.
The Company utilizes an internal risk rating system which is applied to all consumer and 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. 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. 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. Assets identified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of current existing facts, conditions and values, highly questionable and improbable. The possibility of a loss on a doubtful asset is high. However, due to important and reasonably specific pending factors, which may work to strengthen (or weaken) the asset, its classification as an estimated loss is deferred until its more exact status can be determined.
Loss. An asset classified 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.

Variable Interest Entities (VIEs)	Variable Interest Entities ("VIEs")
	The Company previously participated in four private-label securitizations of financial assets involving two HELOC loan transactions and two second mortgage loan transactions. The following private-label securitizations have been reconsolidated or dissolved as a result of settlement agreements. The Company has not engaged in any private-label securitization activity except for these securitizations.
	Due to the Assured Settlement Agreement in 2013, the Company became the primary beneficiary and reconsolidated the FSTAR 2005-1 HELOC securitization trust's assets and liabilities. The Company had elected the fair value option for these assets and liabilities. At December 31, 2014, the Company has a fair value of HELOC loans of $62.9 million and long-term debt of $41.9 million. At December 31, 2013, the Company has a fair value of HELOC loans of $78.0 million and long-term debt of $55.2 million.
	Due to the Assured Settlement Agreement in 2013, the Company became the primary beneficiary and reconsolidated the FSTAR 2006-2 HELOC securitization trust's assets and liabilities. The Company had elected the fair value option for these assets and liabilities. At December 31, 2014, the Company has a fair value of HELOC loans of $68.7 million and long-term debt of $41.8 million. At December 31, 2013, the Company has a fair value of HELOC loans of $77.0 million and long-term debt of $50.6 million.
	Due to the MBIA Settlement Agreement in 2013, the FSTAR 2006-1 mortgage securitization trust was collapsed and the Company consolidated the loans associated with the FSTAR 2006-1 mortgage securitization trust. The Company elected the fair value option for these assets. At December 31, 2014, the Company recorded a fair value of $53.2 million of second mortgage loans. At December 31, 2013, the Company recorded a fair value of $64.7 million of second mortgage loans.
	Consolidated VIEs
	The Company has consolidated VIEs, which consist of the HELOC securitization trusts formed in 2005 and 2006. The Company has determined the trusts are VIEs and has concluded that the Company is the primary beneficiary of these trusts because it has the power to direct the activities of the entity that most significantly affect the entity's economic performance and has either the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. The Company has the power to select the servicer of the whole loans held in the HELOC securitization trust. The beneficial owners of the trusts can look only to the assets of the securitization trusts for satisfaction of the debt issued by the securitization trusts.
	The following table provides a summary of the classifications of consolidated VIE assets and liabilities included in the Consolidated Financial Statements.

	The economic performance of the VIEs is most significantly impacted by the performance of the underlying loans. The principal risks to which the entities were exposed include credit risk and interest rate risk.
	Unconsolidated VIEs
	The Company sponsored nine trust subsidiaries, which issued trust preferred securities to third party investors and loaned the proceeds to the Company in the form of junior subordinated notes. The Company has determined that it is not the primary beneficiary of these entities as it does not possess the power to direct the activities that most significantly impact the economic performance of the VIEs. The Company's maximum exposure to losses is limited to its investment in the trusts, which was $7.4 million at both December 31, 2014 and 2013. See Note 15 of the Notes to the Consolidated Financial Statements, herein, for additional information regarding unconsolidated variable interest entities.
	The Company also has an unconsolidated VIE with which the Company has a significant continuing involvement, but is not the primary beneficiary. The financial assets were derecognized by the Company upon transfer to the FSTAR 2007-1 mortgage securitization trust, which then issued and sold mortgage-backed securities to third party investors. In accordance with the MBIA Settlement Agreement, MBIA is required to satisfy all of its obligation under the FSTAR 2007-1 insurance policy and related FSTAR 2007-1 obligations without further recourse to the Company. At December 31, 2014, the FSTAR 2007-1 mortgage securitization trust included 3,624 loans, with an aggregate principal balance of $141.3 million.

	The Company’s investment in Federal Home Loan Bank ("FHLB") stock was $155.4 million at December 31, 2014 compared to $209.7 million at December 31, 2013.

Transfers and Servicing [Abstract]
Mortgage Servicing Rights	Mortgage Servicing Rights
	The Company has investments in MSRs to support mortgage strategies and to deploy capital at acceptable returns. The Company also deploys derivatives and other fair value assets as economic hedges to offset changes in 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. The primary risk associated with MSRs is the potential value as a result of higher than anticipated prepayments due to loan refinancing prompted, in part, by declining interest rates. Conversely, these assets generally increase in value in a rising interest rate environment to the extent that prepayments are slower than anticipated. 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 12 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments
	Derivative assets and liabilities are recorded at fair value on the Consolidated Statements of Financial Condition, after taking into account the effects of legally enforceable bilateral collateral and master netting agreements. Gross positive fair values are netted with gross negative fair values by counterparty pursuant to a valid master netting agreement. In addition, collateral received from or paid to a given counterparty are considered in this netting. These agreements allow the Company to settle all derivative contracts held with a single counterparty on a net basis in a single currency, and to offset net derivative positions with related collateral, where applicable.
	Counterparty credit risk. The Bank is exposed to credit loss in the event of nonperformance by the counterparties to its various derivative financial instruments. Should a counterparty fail to perform under the terms of a derivative contract, the Company’s counterparty credit risk is equal to the amount reported as a derivative asset in the Consolidated Statements of Condition. The Company manages this risk by selecting only well-established, financially strong counterparties, spreading the credit risk among such counterparties, and by placing contractual limits on the amount of unsecured credit risk from any single counterparty. Counterparties to the Company's derivatives include major financial institutions with investment grade credit ratings from the major rating agencies.
	Collateral agreements require the counterparty to post, on a daily basis, collateral (typically cash or investment securities) equal to the Company’s net derivative receivable. For highly-rated counterparties, the agreements may include minimum dollar posting thresholds, but allow for the Company to call for immediate, full collateral coverage when credit-rating thresholds are triggered by counterparties. The Company’s collateral agreements contain provisions that require collateralization of the Company’s net liability derivative positions. Required collateral coverage is based on certain net liability thresholds. Under circumstances which constitute default under the agreements, the counterparties to the derivatives could request immediate full collateral coverage for derivatives in net liability positions. The Company's collateral agreements in which the collateral is restricted include provisions requiring unilateral funding of coverage for derivatives in net liability positions, as well as minimum collateral positions.
	The Company originates loans and extends credit, both of which expose the Company to interest rate risk. The Company actively manages the overall loan portfolio and the associated interest rate risk in a manner consistent with asset quality objectives. This objective is accomplished primarily through the use of an investment-grade diversified dealer-traded basket of swaps. These transactions may generate fee income, and diversify and reduce overall portfolio interest rate risk volatility. Although the Company utilizes swaps for risk management purposes, they are not treated as or do not qualify as hedging instruments.
	The Company hedges the risk of overall changes in fair value of loans held-for-sale and rate lock commitments generally by selling forward contracts on securities of the Agencies. The forward contracts used to economically hedge the loan commitments are accounted for as non-designated hedges and naturally offset rate lock commitment mark-to-market gains and losses recognized as a component of gain on loan sale. Additionally, the Company hedges the risk of overall changes in fair value of MSRs through the use of various derivatives including purchases of forward contracts on securities of Fannie Mae and Freddie Mac, the purchase/sale of U.S. Treasury futures contracts and the purchase/sale of euro dollar future contracts. These derivatives are accounted for as non-designated hedges against changes in the fair value of MSRs and recognized as a component of net return on mortgage servicing asset.
	The Company uses a combination of derivatives (U.S. Treasury futures, euro dollar futures, swap futures, and "to be announced" forwards with settlement dates beyond the next regular settlement date for such securities) and certain trading securities to hedge the MSRs. For accounting purposes, these hedges represent economic hedges of the MSR asset with both the hedges and the MSR asset carried at fair value on the balance sheet. Certain derivative strategies that the Company uses to manage its investment in MSRs may not fully offset changes in the fair value of such asset due to changes in interest rates and market liquidity.
	The Company writes and purchases interest rate swaps to accommodate the needs of customers requesting such services. Customer-initiated trading derivatives are used primarily to provide derivative products to customers enabling them to manage interest rate risk exposure. The Company mitigates most of the inherent market risk of customer-initiated interest rate swap contracts by entering into offsetting derivative contracts with other counterparties. The offsetting derivative contracts have nearly identical notional values, terms and indices. The difference in the asset and liability is an adjustment for non-performance risk in the measurement of fair value of derivative instruments, which is insignificant. The performance risk is established annually and reviewed quarterly. The Company's interest rate swap agreements are structured such that variable payments are primarily based on LIBOR (one-month, three-month or six-month). Fee income on customer-initiated trading derivatives is earned from entering into various transactions at the request of the customer, primarily interest rate swap contracts. Changes in fair value are recognized in "other noninterest income" on the Consolidated Statements of Operations.
	Fair values of derivative instruments represent the net unrealized gains or losses on such contracts and are recorded in the consolidated balance sheets. Changes in fair value are recognized in the consolidated statements of income. The net gains recognized in income on derivative instruments, net of the impact of offsetting positions, were as follows.

	-2	The interest rate for the notes may adjust monthly and will be subject to (i) a cap based on the weighted average of the loan rates on the mortgage loans, minus the rates at which certain fees and expenses of the issuing entity are calculated and minus any required spread and adjusted for actual days and (ii) a fixed cap of 16.00 percent.
	At December 31, 2014 and 2013 the three-month LIBOR interest rate was 0.26 percent and 0.25 percent, respectively. At both December 31, 2014 and 2013, the one-month LIBOR interest rate was 0.17 percent.
	Trust Preferred Securities
	The trust preferred securities outstanding are callable by the Company and are junior subordinated notes. Under the terms of the related indentures interest is payable quarterly, however, the Company may defer interest payments for up to 20 consecutive quarters without default or penalty. In January 2012, the Company exercised its contractual rights to defer its interest payments with respect to trust preferred securities. The payments are periodically evaluated and will be reinstated when appropriate, subject to the provisions of the Company's Supervisory Agreement and Consent Order. The Company has $20.3 million accrued at December 31, 2014, for these deferred interest payments.
	Notes Associated with Consolidated VIEs
	As previously discussed in Note 8 of the Notes to the Consolidated Financial Statements, herein, the Company determined it was the primary beneficiary of VIEs associated with HELOC securitizations and such VIEs are therefore consolidated in the Consolidated Financial Statements. As of June 30, 2013, the Company reconsolidated the assets and liabilities associated with the HELOC securitization trusts, the proceeds of which were used by the trust to repay outstanding debt.
	The Company has elected the fair value option for these liabilities and changes in fair value are recorded to "other noninterest income" on the Consolidated Statements of Operations. Fair value is estimated using quantitative models which incorporate observable and, in some instances, unobservable inputs including security prices, interest rate yield curves, option volatility, currency, commodity or equity rates and correlations between these inputs. The Company also considers the impact of its own observable credit spreads in the secondary bond markets in determining the discount rate used to value these liabilities. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures.
	The final legal maturities of the long-term debt associated with the VIEs are June 2018 and June 2019, respectively, however these debt agreements have contractual provisions that allow for the debt to be paid off based on the cash flows of the collateral. As of December 31, 2014, the Company's cash flow analysis indicated that the notes are estimated to be paid off by June 2015 for FSTAR 2005-1 (LIBOR plus 0.46 percent) and June 2016 for FSTAR 2006-2 (LIBOR plus 0.16 percent). The estimated maturity dates may change going forward as the inputs used (prepayments, defaults, etc.) for the cash flow analysis will likely change. The debt pays interest based on a spread over the 30-day LIBOR interest rate.

Warrant Liabilities	Warrant Liabilities
	May Investors
	In full satisfaction of the Company’s obligations under anti-dilution provisions applicable to certain investors (the "May Investors") in the Company’s May 2008 private placement capital raise, the Company granted warrants (the "May Investor Warrants") to the May Investors on January 30, 2009 for the purchase of 142,598 shares of Common Stock at $62.00 per share. The holders of such warrants are entitled to acquire shares of Common Stock for a period of ten years. During 2009, May Investors exercised May Investor Warrants to purchase 31,484 shares of Common Stock.
	As a result of the Company’s registered offering on March 31, 2010, of 5.8 million shares of Common Stock at a price per share of $50.00, the number of shares of the Company’s Common Stock issuable to the May Investors under the May Investor Warrants was increased by 26,667 shares and the exercise price was decreased to $50.00 pursuant to the antidilution provisions of the May Investors Warrants.
	As a result of the Company’s registered offering on November 2, 2010 of 11.6 million shares of Common Stock at a price per share of $10.00, the number of shares of Common Stock issuable to the May Investors under the May Investor Warrants was increased by 551,126 shares and the exercise price was decreased to $10.00 pursuant to the antidilution provisions of the May Investors Warrants.
	For the year ended December 31, 2014, no shares of Common Stock were issued upon exercise of May Investor Warrants, and at December 31, 2014, the May Investors held warrants to purchase 688,907 shares at an exercise price of $10.00.
	The May Investor Warrants do not meet the definition of a contract that is indexed to the Company’s own stock under U.S. GAAP. Therefore, the May Investor Warrants are classified as "other liabilities" on the Consolidated Statements of Financial Condition and are measured at fair value, with changes in fair value recognized through operations.
	At December 31, 2014 and 2013, the Company’s liabilities to the holders of May Investors Warrants amounted to $6.3 million and $10.8 million, respectively. Warrant liabilities are valued using a binomial lattice model and are classified within Level 2 of the valuation hierarchy. Significant observable inputs include expected volatility, a risk free rate and an expected life. 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.

	Preferred Stock and Other Warrants
	On January 30, 2009, the Company sold to the U.S. Treasury 266,657 shares of Series C fixed rate cumulative non-convertible perpetual preferred stock ("Series C Preferred Stock") and a warrant to purchase up to approximately 0.7 million shares of Common Stock at an exercise price of $62.00 per share (the "Warrant") for $266.7 million. The issuance and the sale of the Series C Preferred Stock and Warrant were exempt from the registration requirements of the Securities Act of 1933, as amended. The Series C Preferred Stock qualifies as Tier 1 capital and pays cumulative dividends quarterly at a rate of 5 percent per annum for the first five years, and 9 percent per annum thereafter. The Warrant is exercisable through 2019.
	In 2013 the U.S. Treasury sold the Series C Preferred Stock and Warrants which are now held by unrelated third party investors and are no longer held by the U.S. government under the TARP Capital Purchase Program. The warrants are valued utilizing the equity method. In 2013, the U.S. Treasury sold the preferred stock and warrants. The U.S. Treasury also auctioned the Warrant, which closed on June 5, 2013, to purchase up to approximately 645,138 shares of Common Stock at an exercise price of $62.00 per share. At December 31, 2014 and 2013, the Company’s warrant value was $6.3 million and $10.8 million, respectively.
	Preferred stock with a par value of $0.01 and a liquidation value of $1,000 and additional paid in capital attributable to preferred shares at December 31, 2014 is summarized as follows.

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.

	The December 31, 2014 diluted loss per share calculation excludes all Common Stock equivalents, including 1,334,045 shares pertaining to warrants and 263,267 shares pertaining to stock-based awards. The inclusion of these securities would be anti-dilutive.
	Under the terms of the Fixed Rate Cumulative Perpetual Preferred Stock, Series C (the "Series C Preferred Stock") the Company may defer dividend payments. The Company elected to defer dividend payments beginning in February 2012 payment and is currently in arrears in the amount of $56.3 million at December 31, 2014.

	During the year ended December 31, 2014, the effective tax rate was a benefit of 32.9 percent, compared to a not meaningful tax rate during the year ended December 31, 2013 and 29.7 percent for the year ended December 31, 2012. For the year ended December 31, 2014, the effective tax rate varies from the statutory rates primarily due to non-taxable income and expense items, primarily the exclusion of the non-deductible penalty paid to the CFPB and the non-taxable impact of changes related to our warrants. The effective rate during the year ended December 31, 2013 differs from the combined statutory rate principally due to the change in valuation allowance for net deferred taxes, as well as the recognition of the residual tax effect associated with previously unrealized losses on securities recorded in other comprehensive income (loss) had the most significant impacts on the difference between our statutory U.S. federal income tax rate of 35 percent and our effective tax rate.

	During the years ended December 31, 2014 and 2013, the Company had a federal net operating loss carry forwards of $743.1 million and $882.9 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 net operating loss carry forwards that existed at that time. At December 31, 2014 and 2013, $174.1 million of the total net operating loss carry forwards of $743.1 million and $882.9 million respectively, is subject to an annual use limitation of approximately $17.4 million and will expire in calendar years 2028 through 2029.
	The Company has not provided deferred income taxes for the Bank’s pre-1988 tax bad debt reserve of approximately $4.0 million because it is not anticipated that this temporary difference will reverse in the foreseeable future. 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 and profits, or ceases to qualify as a bank for tax purposes.
	At December 31, 2014 and 2013, the deferred tax assets were primarily the result of U.S. net operating loss carryforwards.
	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.
The evaluation of deferred tax assets requires judgment in assessing the likely future tax consequences of events that have been recognized in the financial statements or tax returns and future profitability. The Company's accounting for deferred taxes represents management's best estimate of those future events. Changes in the current estimates, due to unanticipated events or otherwise, could have a material effect on the Company's financial condition and results of operations.
Culminating in the fourth quarter 2013, the Company had taken significant actions to transform its business and reduce uncertainty. These actions included the following:
-1	the retirement of higher cost long-term Federal Home Loan Bank advances;
-2	the related loss on extinguishment of debt as a result of the prepayment of the higher cost long-term Federal Home Loan Bank advances;
-3	the payment of litigation settlement costs incurred in connection with Assured and MBIA litigation settlements;
-4	the sale of mortgage servicing rights while retaining the subservicing; and
-5	the settlements reached with Fannie Mae and Freddie Mac.
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 December 31, 2014. The Company believes that this evidence is sufficient to overcome the unadjusted cumulative losses in recent years.
Other positive evidence considered in connection with the Company's decision to release its federal deferred tax asset valuation allowance include the historic ability to utilize deferred tax assets before they expire, as well as its detailed forecasts projecting the complete realization of all federal deferred tax assets before expiration under the most conservative and stressed earnings scenarios. In order to realize the deferred tax assets, the Company needs to generate approximately $1.1 billion of pre-tax income over the next 20 years. The Company believes this level of pre-tax income will be achievable even under stressed scenarios.
The Company also considered actions taken during the year ended December 31, 2013, which create more certainty regarding its future taxable income including settlements reached with Fannie Mae, Freddie Mac, MBIA and Assured litigation settlements, prepayment of higher cost long-term Federal Home Loan Bank advances and the sale of mortgage servicing rights while retaining the subservicing. The Company has a history of utilizing 100 percent of deferred tax assets before they expire. Forecasts of taxable earnings project a complete realization of all federal deferred tax assets before they expire, including under stressed forecast scenarios. The unprecedented mortgage market conditions have been managed by the Company to minimize the impact should similar volatility recur in the future through cost containment, employee reductions, etc. which give further support to the reliability of forecasted taxable earnings.
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, as of and for the years ended December 31, 2014 and 2013.
The Company had a total state deferred tax asset before valuation allowance of $42.3 million and total state net operating loss carryforwards of $723.6 million at December 31, 2014. 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, 2014, the state deferred tax assets which will more likely than not be realized was $9.3 million and have maintained a valuation allowance of $33.1 million due to 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, 2014, the Internal Revenue Service had completed an examination of the Company through the taxable year ended December 31, 2010. The years open to examination by state and local government authorities vary by jurisdiction.
The following table provides a reconciliation of the total amounts of unrecognized tax benefits for the years ended December 31, 2014, 2013 and 2012.
	December 31,
	2014			2013			2012

Balance at December 31,	$	1,175,632		$	1,277,892		$	837,557
The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. For the years ended December 31, 2014, 2013 and 2012, the Company recognized interest income of approximately $0.3 million and expense of $0.1 million and $0.1 million respectively. In addition, the Company recognized a benefit in penalty of approximately $0.1 million for the year ended December 31, 2014 and no penalty expense for the years ended December 31, 2013 and 2012. The total accrual for interest and penalties related to uncertain tax positions on the balance sheet is not material for the years ended December 31, 2014, 2013 and 2012. At December 31, 2014, approximately $0.2 million of the above tax positions are expected to reverse during the next 12 months, all of which relates to state tax controversies expected to be settled on resolution of a state tax audit.

Regulatory Matters	Regulatory Matters
	Regulatory Capital
	Under capital adequacy guidelines and the regulatory framework for prompt corrective action, 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 classification are also subject to qualitative judgments by regulators about components, risk weightings, and other factors. 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.
	The Bank’s primary regulatory agency, the OCC, requires that the Bank maintain minimum ratios of tangible capital, which are shown in the following table.
	31-Dec-14	Regulatory Minimums		Regulatory Minimums to be Well-Capitalized
	Basel I Ratios
	Tier 1 leverage ratio	4	%	5	%
	Tier 1 risk-based capital ratio	4	%	6	%
	Total risk-based capital ratio	8	%	10	%
	To be categorized as "well capitalized," the Bank must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the table below. The Bank is considered "well capitalized" at both December 31, 2014 and 2013. There have been no conditions or events that management believes have changed the Bank’s category.
	The following table shows the regulatory capital ratios as of the dates indicated. These ratios are applicable to the Bank only.

	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, which the OCC terminated simultaneous with issuance of the Consent Order. The Company is still subject to the Supervisory Agreement with the Federal Reserve (discussed below).
	Under the Consent Order, the Bank is required to adopt or review and revise various plans, policies and procedures related to, among other things, regulatory capital, enterprise risk management and liquidity. Specifically, under the terms of the Consent Order, the Bank's board of directors has agreed to, among other things, which include but 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 is 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 complete description of all of the terms of the Supervisory Agreement and is qualified in its entirety by reference to the copy of the Supervisory Agreement 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 is currently subject to regulatory capital rules based on the framework established by the 1988 capital accord (“Basel I”) of the Basel Committee on Banking Supervision. Savings and loan holding companies are not subject to the Basel I capital requirements. In July 2013, the Federal Reserve Board and the FDIC promulgated interim final rules implementing Basel III, providing for a strengthened set of capital requirements, as well as a standardized risk-weighting approach. In October 2013, the OCC and Federal Reserve adopted a final rule consistent with Basel III that replaces their existing risk-based and leverage capital rules. The Bank and Bank Holding Company are subject to the capital requirements of the Basel III rules effective January 1, 2015.
	The capital framework under the Basel III final rule will replace the existing 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. Effective on January 1, 2015 the final rules require the Bank and Holding Company to maintain Tier 1 capital of at least 6 percent of risk-weighted assets and off-balance sheet items, total capital (the sum of Tier 1 capital and Tier 2 capital) of at least 8 percent of risk-weighted assets and off-balance sheet items, and Tier 1 capital of at least 4 percent of adjusted quarterly average assets. In addition, the final rule implements a new common equity Tier 1 minimum capital requirement of at least 4.5 percent of risk-weighted assets.
	In addition, the new regulations would 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 will be 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, which the Company has used in the past as a tool for raising additional Tier 1 capital and otherwise improving its regulatory capital ratios. Although the Company may continue to include our existing trust preferred securities as Tier 1 capital, the prohibition on the use of these securities as Tier 1 capital going forward may limit the Company’s ability to raise capital in the future.

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings, Contingencies and Commitments	Legal Proceedings, Contingencies and Commitments
	On at least a quarterly basis, the Company assesses the liabilities and loss contingencies in connection with pending or threatened legal and regulatory proceedings utilizing the latest information available. The Company establishes accruals for legal claims and regulatory matters 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 from time to time, as appropriate, in light of additional information.
	Legal Proceedings
	The Company and certain subsidiaries are subject to various pending or threatened legal proceedings arising out of the normal course of business or operations. On the basis of information currently available, advice of counsel, available insurance coverage, and established reserves, it is the opinion of management that the eventual outcome of the current actions against us will not have a material adverse effect on our consolidated financial condition, results of operations, or cash flows. However, it is possible that the ultimate resolution of legal matters, if unfavorable, may be material to our consolidated financial condition, results of operations, or cash flows in a particular period.
	From time to time, governmental agencies 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. 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.
	On August 15, 2013, shareholder Kenneth Taylor filed a derivative action against several current and former members of the Company's board of directors and executive officers. The lawsuit requests unspecified monetary damages and purports to seek to remedy defendants’ alleged breaches of fiduciary duties and unjust enrichment from 2011 to present, focusing on the events leading up to the Company's February 24, 2012 settlement with the U.S. Department of Justice, as well as the settlement itself. On October 23, 2013, Joel Rosenfeld filed a second derivative action in the same court alleging similar claims based on the February 24, 2012 settlement, as well as Flagstar’s prior litigation with Assured Guaranty. The Court consolidated the matters and appointed Rosenfeld as lead plaintiff and Rosenfeld’s counsel and lead plaintiffs’ counsel. The plaintiffs then filed a consolidated complaint. The parties have been facilitating the matter and the litigation has been stayed while they do so. A parallel action was filed by Kenneth Taylor on January 24, 2014 in the Federal Court for the Eastern District of Michigan. The Taylor matter was also stayed by the court to allow the parties to facilitate.
	In May 2012, the Bank and its subsidiary, Flagstar Reinsurance Company, were named as defendants in a putative class action lawsuit alleging a violation of Section 2607 of the Real Estate Settlement Procedures Act ("RESPA"). The Court granted summary judgment on June 26, 2014, and dismissed the case. Rather than proceed with an appeal, the parties have reached an agreement in principle to settle the matter. Management does not believe that the settlement amount will be material to the Company’s results of operations.
	Consumer Financial Protection Bureau Settlement
	On August 26, 2014, the Company disclosed that the Bank had commenced discussions with the Consumer Financial Protection Bureau ("CFPB"), related to alleged violations of federal consumer financial laws arising from the Bank’s loss mitigation practices and default servicing operations dating back to 2011. On September 29, 2014, the Bank reached a settlement with the CFPB pursuant to the CFPB Consent Order. The settlement required the Bank to pay $27.5 million to the CPFB for borrower remediation and $10.0 million in civil monetary penalties. The settlement did not involve any admission of wrongdoing on the part of the Company or its employees, directors, officers or agents.
	DOJ litigation settlement
	Per the February 2012 DOJ Agreement, the Company is required to make future additional payments of approximately $118.0 million contingent upon the occurrence of certain future events. The Company elected the fair value option to account for this liability and uses a discounted cash flow model to measure fair value. The fair value of the DOJ liability was $81.6 million and $93.0 million using a discount rate of 8.7 percent and 9.9 percent at December 31, 2014 and 2013 respectively. The undiscounted amount of the DOJ liability remains at $118.0 million.
	The DOJ Agreement does not have any effect on FHA insured loans in the Company's portfolio, including loans classified as loans repurchased with government guarantees as discussed in Notes 1 and 4 of the Notes to the Consolidated Financial Statements, herein.
	Litigation Accruals
	As of December 31, 2014, the Company's total accrual for contingent liabilities was $86.3 million, which includes the fair value liability relating to the DOJ Agreement and other pending cases.
	Commitments
	A summary of the contractual amount of significant commitments is as follows.
		December 31,
		2014		2013
		(Dollars in thousands)
	Commitments to extend credit
	Mortgage loans (interest-rate lock commitments)	$	2,171,890	$	1,857,775
	HELOC trust commitments	88,291		67,060
	Other consumer commitments	7,326		7,430
	Standby and commercial letters of credit	9,502		7,982
	Other commercial commitments	444,880		296,713
	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.
	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 as an other asset. Further discussion on derivative instruments is included in Note 12 of the Notes to the Consolidated Financial Statements, herein.
	The Company has unfunded commitments under its contractual arrangement with the HELOC securitization trusts to fund future advances on the underlying HELOC. Refer to further discussion of this issue as presented in Note 8 of the Notes to the Consolidated Financial Statements, herein.
	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.
	These instruments involve, to varying degrees, elements of credit and interest rate risk beyond the amount recognized on the Consolidated Statement of Financial Condition. The contractual amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments. 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.
	Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. 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 counter parties.
	The Company maintains a reserve for letters of credit which is included in other liabilities, 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 $1.4 million and less than $0.1 million for December 31, 2014 and 2013, respectively, are reflected in other liabilities on the Consolidated Statements of Operations.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements
	The Company utilizes fair value measurements to record certain assets and liabilities at fair value. A description of the valuation methodologies used for instruments measured at fair value is provided in Note1, above, of the Notes to the Consolidated Financial Statements, herein,
	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, 2014 and 2013, by caption on the Consolidated Statements of Financial Condition and by the valuation hierarchy (as described above).

The Company transferred $3.5 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.
A determination to classify a financial instrument within Level 3 of the valuation hierarchy is based upon the significance of the unobservable inputs to the overall fair value measurement. The Company manages the risk associated with the observable components of Level 3 financial instruments using securities and derivative positions that are classified within Level 1 or Level 2 of the valuation hierarchy. If the market for an instrument becomes more liquid or active and pricing models become available which allow for readily observable inputs, the Company will transfer the instruments from Level 3 to Level 2 valuation hierarchy. The assets and/or liabilities transferred are valued at the end of the period. Gains and losses in the tables do not reflect the effect of the Company's risk management activities related to such Level 3 instruments

Recurring Significant Unobservable Inputs
The significant unobservable inputs used in the fair value measurement of the second mortgage loans associated with the FSTAR 2006-1 mortgage securitization trust are discount rates, prepayment rates and default rates. Significant increase (decreases) in the discount rate in isolation would result in a significantly lower (higher) fair value measurement. Increases in both prepay rates and default rates in isolation result in a higher fair value; however, generally a change in the assumption used for the probability of default is accompanied by a directionally opposite change in the assumption used for prepayment rates, which would offset a portion of the fair value change.
The significant unobservable inputs used in the fair value measurement of the HELOC securitization trusts are internal rates of return, discount rates, prepayment rates, loss rates and loss severity. For the assets, increases (decreases) in the internal rate of return in isolation would result in a lower (higher) fair value measurement; increases (decreases) in prepay rates in isolation would result in a higher (lower) fair value measurement; while increases (decreases) in defaults and loss severities in isolation would result in a lower (higher) fair value. For the liabilities, increases (decreases) in the discount rate in isolation would result in a lower (higher) fair value measurement; increases (decreases) in prepayment rates 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 the assumptions in isolation would result in a significantly lower (higher) fair value measurement. The fair value of MSRs is estimated using a valuation model that calculates the present value of estimated future net servicing cash flows, taking into consideration expected mortgage loan prepayment rates, discount rates, servicing costs, and other economic factors, which are determined based on current market conditions. The Company obtains third-party valuations of its MSRs on a quarterly basis to assess the reasonableness of the fair value calculated by the valuation model. In certain circumstances, based on the probability of the completion of a sale of MSRs pursuant to a bona-fide purchase offer, the Company considers the bid price of that offer and identifiable transaction costs in comparison to the calculated fair value and may adjust the estimate of fair value to reflect the terms of the pending transaction.
The key economic assumptions used in determining the fair value of those MSRs capitalized during the years ended December 31, 2014, 2013 and 2012 were as follows.
	For the Years Ended December 31,
	2014			2013			2012
Weighted-average life (in years)	7.8			6.1			6.1
Weighted-average constant prepayment rate	12.3	%		13.8	%		14.8	%
Weighted-average discount rate	11.7	%		8.5	%		7.1	%
The key economic assumptions reflected in the overall fair value of the entire portfolio of MSRs were as follows.
	December 31,
	2014			2013			2012
Weighted-average life (in years)	6.6			7.3			5.3
Weighted-average constant prepayment rate	15	%		11.9	%		17.3	%
Weighted-average discount rate	10.9	%		10.2	%		7	%
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 fall out 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. Generally, a change in the assumption utilized for the probability of default is accompanied by a directionally similar change in the assumption utilized for the loss severity and a directionally opposite change in assumption utilized for prepayment rates.
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 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). The Bank's target asset growth rate post 2015 is based off of growth in the balance sheet. Significant increases (decreases) in the bank's growth rate in isolation could result in a significantly lower (higher) fair value measurement. Significant increases (decreases) in the bank's MSR growth rate in isolation could result in a marginally lower (higher) fair value measurement. Significant increases (decreases) in the peer group's return on assets improvement in isolation could result in a marginally higher (lower) fair value measurement. Significant increases (decreases) in the bank's return on assets improvement 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 non-recurring 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.

The methods and assumptions used by the Company in estimating fair value of financial instruments which are required for disclosure only, are as follows:
Cash and cash equivalents. Due to their short-term nature, the carrying amount of cash and cash equivalents approximates fair value.
Loans repurchased 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 by using internally developed discounted cash flow models using market interest rate inputs as well as management’s best estimate of spreads for similar collateral.
Federal Home Loan Bank stock. No secondary market exists for 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.
Deposit accounts. The fair value of demand deposits and savings accounts approximates the carrying amount. 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 above of the Notes to the Consolidated Financial Statements, herein, to mitigate a divergence between accounting losses and economic exposure.
The following table reflects the change in fair value included in earnings (and the account recorded in) for the assets and liabilities for which the fair 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. Certain prior period amounts have been reclassified to conform to current year presentation.
	In January 2014, the Company reorganized the way its operations are managed based on core functions. The segments are based on an internally-aligned segment leadership structure, which is also how the results are monitored and performance assessed. The Company expects that the combination of the business model and the services that the operating segments provide will result in a competitive advantage that supports revenue and earnings. The Company's business model emphasizes the delivery of a complete set of mortgage and banking products and services, including originating, acquiring, selling and servicing one-to-four family residential mortgage loans, which we believe is distinguished by timely processing and customer service.
	The Mortgage Originations segment originates, acquires and sells one-to-four family residential mortgage loans. The origination and acquisition of mortgage loans comprises the majority of the lending activity. Mortgage loans are originated through home loan centers, national call centers, the Internet and unaffiliated banks and mortgage banking and brokerage companies, where the net interest income and the gains from sales associated with these loans are recognized in the Mortgage Originations segment.
	The Mortgage Servicing segment services and subservices mortgage loans, on a fee basis, for others. Also, the Mortgage Servicing segment services, on a fee basis, residential mortgages 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 earn 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, charges or credits of an unusual or infrequent nature that are not reflective of the normal operations of the operating segments 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, hedging 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 maybe subject to periodic adjustment as the internal management accounting system is revised and the business or product lines within the segments change. Also, because the development and application of these methodologies is a dynamic process, the financial results presented may be periodically revised.
	The following tables present financial information by business segment for the periods indicated.

Description of Business, Basis of Presentation, and Summary of Significant Accounting Standards (Policies)	12 Months Ended
	Dec. 31, 2014
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 reporting policies of Flagstar and the methods of applying those policies that materially affect the consolidated financial statements conform with accounting principles generally accepted in the United States ("GAAP") and with general financial services industry practices. Certain prior period amounts have been reclassified to conform to the current period presentation.
Use of Estimates	Use of Estimates
	The preparation of Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. Actual results could materially differ from the reported amounts due to estimates and assumptions used in a variety of areas, including but not limited to, assets and liabilities measured at fair value, other litigation accruals, the allowance for loan losses and the representation and warranty reserve.
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.
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash on hand, cash items and amounts due from correspondent banks and the Federal Reserve Bank are included in cash and cash equivalents. Short-term investments that have a maturity at the date of acquisition of three months or less and are readily convertible to cash are considered cash equivalents.
Investment Securities	Investment Securities
	Trading securities are debt and equity securities that we purchase and hold but intend to sell in the near term. These assets are recorded at fair value in the Company’s Consolidated Statements of Financial Condition, with unrealized and realized gains or losses included as a component of "gain on trading securities" in the Consolidated Statements of Operations. As of December 31, 2014, the Company had no trading securities.
	The Company measures available-for-sale securities at fair value in the Consolidated Statements of Financial Condition, with unrealized gains and losses, net of tax, included in "other comprehensive income (loss)" in shareholders’ 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 "net gain on securities available-for-sale" in the Consolidated Statements of Operations.
	The fair value of available-for-sale 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 curves or other factors. The fair values are obtained through independent third parties from pricing services which the Company compares to independent pricing sources. Also included in available-for-sale securities is a municipal obligation which is valued based on similar non-rated bonds and cost approximates fair value. 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.
	The Company evaluates available-for-sale 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 cost and the Company intends to sell or it is more likely than not that the Company will be required to sell the security before recovery when a credit loss exists. At December 31, 2014, the Company had no OTTI on the available-for-sale investment securities held.
	Any security for which there has been an OTTI is written down to its estimated fair value through a charge to earnings 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. Realized securities gains and declines in value judged to be other-than-temporary representing credit losses are included in "net impairment losses" in the Consolidated Statements of Operations.
	Investment transactions are recorded on the trade date. Interest earned on 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.
Reverse Repurchase Agreements	Reverse Repurchase Agreement
	The fair value of the reverse repurchase agreement is determined by cost, which approximates the fair value. The reverse repurchase agreement is guaranteed by a third party and secured by government and agency securities, which are held by a third party. In case of default, the Company would receive the collateral from the third party. The reverse repurchase agreement is included in other assets on the Consolidated Statements of Financial Condition and in Note 24 as an other investment. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional information on recurring fair value and investment security disclosures.
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. For loans originated that the Company intends to sell, the Company has elected the fair value option. 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 is determined by discounting estimated cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures.
	Loans are transferred into the held-for-sale portfolio from the held-for-investment portfolio when there is an intent to sell these loans. Loans held-for-sale are recorded at lower of cost or fair value. Gains or losses recognized upon the sale of loans are determined using the specific identification method.
Loans Held-for-Investment	Loans Held-for-Investment
	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 deferred and unamortized cost basis adjustments, including purchase premiums, discounts and other cost basis adjustments (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.
	As a result of the Company carrying its mortgage loans held-for-sale at fair value, any transfers of loans held-for-sale to loans held-for-investment continue to be measured and reported at fair value on a recurring basis with any changes in fair value reported in the Company’s Consolidated Statements of Operations. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures.
	Also included in loans held-for-investment are the reconsolidated VIE loans associated with the FSTAR 2005-1, 2006-1, and 2006-2 securitization trusts. The Company elected the fair value option for these assets and changes in fair value are recorded to "other noninterest income" on the Consolidated Statements of Operations. Fair value of these loans is calculated using a discounted cash flow model which utilizes observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral.
	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 rather than their current classification. As a result of the Company carrying its mortgage loans held-for-sale at fair value, any transfers of loans held-for-sale to loans held-for-investment continue to be reported at fair value with any changes in fair value reported in the Company’s Consolidated Statements of Operations.
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, which includes reductions of interest rate, extensions of amortization period, principal and/or interest forgiveness and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral. If the 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 only of past due amounts.
Past Due Loan 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 due. While it is the goal of management to collect on loans, a method we use is to work out a satisfactory repayment schedule or modification with a past due borrower, we 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 customarily mails several notices of past due payments to the borrower within 30 days after the due date and late charges are assessed in accordance with certain parameters. The Company's collection department makes telephone or personal contact with borrowers after loans are 30 days past due. In certain cases, the Company recommends that the borrower seek credit-counseling assistance and may grant forbearance if it is determined that the borrower is likely to correct a past due loan within a reasonable period of time. The Company ceases the accrual of interest on loans that we classify as "nonperforming" once they become 90 days past due or earlier when concerns exist as to the ultimate collection of principal or interest. Subsequently, interest is recognized as income only when it is actually collected.
	For all classes within the consumer and commercial loan portfolio, loans are placed on nonaccrual status when any portion of principal or interest is 90 days past due (or nonperforming), or earlier when the Company becomes aware of information indicating that collection of principal and interest is in doubt. When a loan is placed on nonaccrual status, the accrued interest income is reversed. Loans 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 (or nonperforming). See Note 24 of the Consolidated Financial Statements, herein, for additional non-recurring 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. 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 consumer portfolio segment includes residential first mortgages, second mortgages, HELOC and other consumer loans. The commercial portfolio segment includes commercial real estate, commercial and industrial, commercial lease financing and warehouse lending loans. 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, as of the date of the consolidated financial statements. 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).
	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. Fair value 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 if the loan is collateral dependent, reduced by estimated disposal costs.    A general allowance for losses inherent on non-impaired loans is calculated using 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 history is normally a one- to five-year rolling average updated periodically as new data becomes available. In addition to the loss history, the Company will also include a qualitative adjustment that considers economic risks, industry and geographic concentrations and other factors not adequately captured in the Company's loss methodology.
	Consumer loans.  For consumer loans that have not been identified for evaluation for impairment, the allowance for loan losses is determined based on a collective basis utilizing forecasted losses that represent management’s best estimate of inherent loss. Loans are pooled by loan types with similar risk characteristics. Historical loss models designed for each pool are utilized to develop the loss estimates based on historical losses. Management evaluates the results of the allowance for loan losses model and makes qualitative adjustments to the results of the model when it is determined that model results do not reflect all losses inherent in the loan portfolios due to changes in recent economic trends and conditions, or other relevant factors.
	For consumer 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.
	Loans secured by real estate are charged-off to the estimated fair value of the collateral when a loss is confirmed or at 120 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.
	Commercial loans. Commercial loans are assessed for estimated losses by grouping the portfolio into two segments based on underwriting and origination characteristics: legacy and new. For both segments, management observes historical losses over a relevant period. These loss estimates are adjusted as appropriate based on additional analysis of long-term average loss experience compared to previously forecasted losses, external loss data or other risks identified from current economic conditions and credit quality trends.
	The commercial loan portfolio is segmented into loans originated prior to January 1, 2011 and loans originated on or after January 1, 2011, while still retaining the segmentation by product type. The loss rates attributed to the loans originated prior to January 1, 2011 portfolio are based on historical losses of this segment. Due to the brief period of time that loans in the loans originated on or after January 1, 2011 portfolio have been outstanding, and thus the absence of a sufficient loss history for that portfolio, the Company uses loss data from a third party data aggregation firm (adjusting for the qualitative factors) as a proxy for estimating an allowance for loan losses. The Company separately identifies a population of commercial banks with similar size balance sheets (and loan portfolios) to serve as the Company's peer group. The Company utilizes this peer group's publicly available historical loss data (adjusted for the qualitative factors) as a proxy for loss rates used to determine the allowance for loan losses on the loans originated on or after January 1, 2011 commercial portfolio.
	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.
	Potential losses that may not be reflected in our model assumptions are captured through the qualitative factor adjustments discussed above. Management reviews these models on an ongoing basis and updates them as appropriate to reflect then-current industry conditions, heightened access to enhanced loss data and based upon continuous back testing of the allowance for loan losses model.
Loan Sales	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 whether the transferee would be a consolidated affiliate, the existence and extent of any continuing involvement in the transferred financial assets and 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 and judgment must 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. See Note 24 of the Notes to the Consolidated Financial Statements, herein, for additional non-recurring fair value disclosures.
Loans Repurchased with Government Guarantees	Loans Repurchased with Government Guarantees
	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 and recognizes the loans as loans repurchased with government guarantees on the Consolidated Statements of Financial Condition and also recognizes a corresponding liability for a similar amount recorded in other liabilities on the Consolidated Statement of Financial Condition. If the loans are actually repurchased, the Company records the loans to loans repurchased with government guarantees and eliminates the corresponding liability.
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 exists 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 approach 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. For the mortgage servicing rights, the gains and losses recorded in earnings are included in "net return on mortgage servicing" on the Consolidated Statements of Operations. 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 accounting model used to determine if the transfer of an MSR asset qualifies as a sale is based on a risks and rewards approach. Upon completion of MSR sales, we account for the transactions as a sale and derecognize the mortgage servicing rights from the Consolidated Statements of Financial Condition.
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 loan administration income.
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 hedges 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 hedge the cash flows on certain liabilities. The Company does not elect to apply or does not qualify for hedge accounting and therefore accounts for the derivatives as economic undesignated derivatives.
	The Company recognizes all derivatives as either other assets or other liabilities in the Consolidated Statements of Financial Condition at their fair value. 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 also enters into various derivative agreements with customers desiring protection from possible adverse future fluctuations in interest rates using 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.
	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, 2014 and 2013, 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 interest rate risk exposure. 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.
	Additional information regarding the accounting for derivatives is provided in Note 12 and additional recurring fair value disclosures in Note 24 of the Notes to the Consolidated Financial Statements, herein.
Income Taxes	Income Taxes
	Our income tax expense, deferred tax assets and liabilities, and reserves for unrecognized tax benefits reflect management’s best assessment of estimated future taxes to be paid. Significant judgments and estimates are required in determining the income tax expense and the Company is subject to the income tax laws of the U.S., its states and municipalities.
	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 records a valuation allowance to reduce its deferred tax assets to the amount it believes will be realized if, based on available evidence at the time the determination is made, it is more likely than not that some or all of the deferred tax assets will not be realized.
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 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. 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 regarding loan repurchases and indemnifications, and loss severity on repurchased and indemnified loans, among other factors. Increases to the representation and warranty reserve for current loan sales reduce the Company’s net gain on loan sales. Adjustments to the Company’s previous estimates are recorded as an increase or decrease to 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" expenses 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.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements
	In January 2014, the FASB issued ASU No. 2014-04, "Receivables-Troubled Debt Restructurings by Creditors (Topic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure." The guidance amends the guidance in the FASB Accounting Standards Codification Topic 310-40, "Receivables - Troubled Debt Restructurings by Creditors," in efforts to reduce diversity in practice through clarifying when an in substance repossession or foreclosure occurs. Essentially, the guidance addresses when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan so that the loan should be derecognized and the real estate property recognized in the financial statements. This guidance is effective prospectively, for annual and interim periods, beginning after December 15, 2014. The Company's current policy reflects the practices discussed in this guidance. Therefore, the adoption of the guidance is not expected to have a material impact on the consolidated financial statements or the Notes thereto.
	In April 2014, the FASB issued ASU No. 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." The amendments in this guidance will allow discontinued operations to include a component of an entity or a group of components of an entity. A disposal is required to be reported in discontinued operations if it represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. This guidance is effective prospectively, for annual and interim periods, beginning after December 15, 2014. The adoption of the guidance is not expected to have a material effect on the Company’s Consolidated Financial Statements or the Notes thereto.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." Under the amended guidance, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance is effective prospectively, for annual and interim periods, beginning after December 15, 2016. 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 disclosures to the Notes thereto will be required.
	In June 2014, the FASB issued ASU No. 2014-11, "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financing, and Disclosures." The amendments in this guidance requires repurchase-to-maturity transactions to be accounted for as secured borrowings. The guidance for certain transactions accounted for as a sale, repurchase agreements, securities lending transactions and repurchase-to-maturity transactions accounted for as secured borrowings is effective prospectively, for annual and interim periods, beginning after December 15, 2014. The adoption of the guidance is not expected to have a material effect on the Company’s Consolidated Financial Statements or the Notes thereto.
	In August 2014, the FASB issued ASU No. 2014-13, Consolidation (Topic 810). A reporting entity that consolidates a collateralized financing entity within the scope of this update may elect to measure the financial assets and the financial liabilities of that collateralized financing entity using either the measurement alternative included in this update or Topic 820 on fair value measurement. When the measurement alternative is not elected for a consolidated collateralized financing entity within the scope of this update, the amendments clarify that (1) the fair value of the financial assets and the fair value of the financial liabilities of the consolidated collaterlized financing entity should be measured using the requirements of Topic 820 and (2) any differences in the fair value of the financial assets and the fair value of the financial liabilities of that consolidated collateralized financing entity should be reflected in earnings and attributed to the reporting entity in the consolidated statement of income (loss). The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. The Company's current policy reflects the practices discussed in this guidance. Therefore, 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 August 2014, the FASB issued ASU Update No. 2014-14, Receivables - Troubled Debt Restructuring by Creditors (Subtopic 310-40). The amendments in this update require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) the loan has a government guarantee that is not separable from the loan before foreclosure, (2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim, and (3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amendments in this update are effective for public business entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The adoption of this guidance is expected to move approximately $372.8 million of repossessed assets and claims receivable to other assets on the Consolidated Statements of Financial Condition.
	In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40). In connection with preparing financial statements for each annual and interim reporting period, an entity's management should evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). Management's evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued (or at the date that the financial statements are available to be issued when applicable). The amendments in this update are effective for the annual period ending after December 15, 2016, and for annual periods and interim 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 January 2015, the FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual items (Subtopic 22-20). The amendments in this update eliminate the concept of extraordinary items. The amendments in this update are 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.
