Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying financial statements of Flagstar Bancorp, Inc. ("Flagstar," or the "Company"), including its wholly owned principal subsidiary, Flagstar Bank, FSB (the "Bank"), have been prepared using U.S. generally accepted accounting principles ("GAAP") for interim financial statements. Where we say "we," "us," or "our," we usually mean Flagstar Bancorp, Inc. However, in some cases, a reference to "we," "us," or "our" will include our wholly owned subsidiary Flagstar Bank, FSB (the "Bank"). These consolidated financial statements do not include all of the information and footnotes required by GAAP for a full year presentation and certain disclosures have been condensed or omitted in accordance with rules and regulations of the Securities and Exchange Commission. These interim financial statements are unaudited and include, in our opinion, all adjustments necessary for a fair statement of the results for the periods indicated, which are not necessarily indicative of results which may be expected for the full year. These consolidated financial statements and notes should be read in conjunction with the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015 , which is available on our website, at flagstar.com, and on the SEC website, at sec.gov. Certain prior period amounts have been reclassified to conform to the current period presentation.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Investment Securities As of March 31, 2016 and December 31, 2015 , investment securities were comprised of the following: Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (Dollars in millions) March 31, 2016 Available-for-sale securities Agency - Commercial $ 755 $ 12 $ — $ 767 Agency - Residential 497 10 — 507 Municipal obligations 39 1 — 40 Total available-for-sale securities (1) $ 1,291 $ 23 $ — $ 1,314 Held-to-maturity securities Agency - Commercial $ 641 $ 8 $ — $ 649 Agency - Residential 612 9 — 621 Total held-to-maturity securities (1) $ 1,253 $ 17 $ — $ 1,270 December 31, 2015 Available-for-sale securities Agency - Commercial $ 766 $ 3 $ (3 ) $ 766 Agency - Residential 514 2 (2 ) 514 Municipal obligations 14 — — 14 Total available-for-sale securities (1) $ 1,294 $ 5 $ (5 ) $ 1,294 Held-to-maturity securities Agency - Commercial $ 634 $ — $ (2 ) $ 632 Agency - Residential 634 — (4 ) 630 Total held-to-maturity securities (1) $ 1,268 $ — $ (6 ) $ 1,262 (1) There were no securities of a single issuer, which are not governmental or government-sponsored, that exceeded 10 percent of stockholders’ equity at March 31, 2016 or December 31, 2015 . Credit related declines in the available-for-sale and held-to-maturity securities are classified as other than temporary impairments ("OTTI") and are reported as a separate component of noninterest income within the Consolidated Statement of Operations. An impaired investment security is considered to be other than temporary if (1) we intend to sell the security; (2) it is more likely than not we will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not sufficient to recover all contractually required principal and interest payments. We evaluate our securities portfolio each quarter to determine if any security is considered to be other than temporarily impaired. In making this evaluation, management considers its ability and intent to hold securities to recover current market losses. During the three months ended March 31, 2016 and December 31, 2015 , we had no other-than-temporary impairments ("OTTI"). Available-for-sale securities Securities available-for-sale are carried at fair value, with unrealized gains reported as a component of other comprehensive income and unrealized losses reported as a component of other comprehensive income to the extent they are temporary in nature. We purchased $27 million of available-for-sale securities, which included U.S. government sponsored agency mortgage-backed securities and municipal obligations, during the three months ended March 31, 2016 . We purchased $652 million of available-for-sale securities, which included U.S. government sponsored agencies, comprised of mortgage-backed securities and collateralized mortgage obligations during the three months ended March 31, 2015 . Gains (losses) on sales of available-for-sale securities are reported in other noninterest income in the Consolidated Statements of Operations. During the three months ended March 31, 2016 and March 31, 2015 , there were no sales of available-for-sale securities, except those related to mortgage loans that had been securitized for sale in the normal course of business. During the three months ended March 31, 2015 , $2 million of municipal obligations matured. Held-to-maturity securities Investment securities held-to-maturity are carried at amortized cost and adjusted for amortization of premiums and accretion of discounts using the interest method. Transfers of investment securities into the held-to-maturity category from the available-for-sale category are accounted for at fair value at the date of transfer. The related unrealized holding gain, net of tax, that was included in the transfer is retained in other comprehensive income and is being amortized as an adjustment to interest income over the remaining life of the securities. We purchased $15 million of held-to-maturity securities, which included U.S. government sponsored agency mortgage-backed securities during the three months ended March 31, 2016 . During the three months ended March 31, 2015 , we had no purchases of held-to-maturity securities. Gains (losses) on sales of held-to-maturity securities are reported in other noninterest income in the Consolidated Statements of Operations. There were no sales of held-to-maturity securities during the three months ended March 31, 2016 and March 31, 2015 . The following table summarizes by duration the unrealized loss positions on investment securities: Unrealized Loss Position with Duration 12 Months and Over Unrealized Loss Position with Duration Under 12 Months Fair Value Number of Securities Unrealized Loss Fair Value Number of Securities Unrealized Loss Type of Security (Dollars in millions) March 31, 2016 Available-for-sale securities Agency - Commercial $ 13 3 $ — $ 71 7 $ — Agency - Residential $ 22 1 $ — $ — — $ — Held-to-maturity securities Agency - Commercial $ — — $ — $ 58 4 $ — Agency - Residential $ — — $ — $ 24 4 $ — December 31, 2015 Available-for-sale securities Agency - Commercial $ — — $ — $ 482 27 $ (3 ) Agency - Residential $ 8 2 $ — $ 224 15 $ (2 ) Held-to-maturity securities Agency - Commercial $ — — $ — $ 471 27 $ (2 ) Agency - Residential $ — — $ — $ 547 50 $ (4 ) The amortized cost and estimated fair value of securities at March 31, 2016 , are presented below by contractual maturity: Investment Securities Available-for-Sale Investment Securities Held-to-maturity Amortized Cost Fair Value Weighted Average Yield Amortized Cost Fair Value Weighted Average Yield March 31, 2016 (Dollars in millions) (Dollars in millions) Due after one year through five years $ 6 $ 6 1.98 % $ — $ — — % Due after five years through 10 years 26 27 3.50 % 61 62 2.50 % Due after 10 years 1,259 1,281 2.56 % 1,192 1,208 2.42 % Total $ 1,291 $ 1,314 $ 1,253 $ 1,270 We pledge investment securities, primarily municipal taxable and agency collateralized mortgage obligations, to collateralize lines of credit and/or borrowings.

Receivables Held-for-sale [Abstract]
Loans Held-for-Sale	Loans Held-for-Sale The majority of our mortgage loans originated as loans held-for-sale are sold into the secondary market on a whole loan basis or by securitizing the loans into securities. At both March 31, 2016 and December 31, 2015 , loans held-for-sale totaled $2.6 billion , respectively. For the three months ended March 31, 2016 , we reported net gain on loan sales of $75 million , compared to $91 million net gain on loan sales during the three months ended March 31, 2015 . At March 31, 2016 and December 31, 2015 , $20 million and $35 million , respectively, of loans held-for-sale were recorded at lower of cost or fair value. The remainder of the loans in the portfolio are recorded at fair value as we have elected the fair value option for such loans.

Loans and Leases Receivable Disclosure [Abstract]
Loans with Government Guarantees	Loans with Government Guarantees The majority of loans with government guarantees are insured or guaranteed by the Federal Housing Administration. These loans earn interest at a rate based upon the 10 -year U.S. Treasury note rate at the time the underlying loan becomes delinquent, which is not paid by the FHA until claimed. At March 31, 2016 and December 31, 2015 , loans with government guarantees totaled $462 million and $485 million , respectively. At March 31, 2016 , repossessed assets and the associated claims recorded in other assets totaled $202 million and $210 million at December 31, 2015 .

Loans Held-for-Investment	Loans Held-for-Investment Loans held-for-investment are summarized as follows: March 31, December 31, (Dollars in millions) Consumer loans Residential first mortgage $ 2,410 $ 3,100 Second mortgage 129 135 HELOC 366 384 Other 31 31 Total consumer loans 2,936 3,650 Commercial loans Commercial real estate 851 814 Commercial and industrial 571 552 Warehouse lending 1,282 1,336 Total commercial loans 2,704 2,702 Total loans held-for-investment 5,640 6,352 Less allowance for loan losses (162 ) (187 ) Loans held-for-investment, net $ 5,478 $ 6,165 For the three months ended March 31, 2016 and March 31, 2015 , we transferred zero and $5 million , respectively, of loans held-for-sale to loans held-for-investment. During the three months ended March 31, 2016 , we sold nonperforming, TDR and non-agency loans with unpaid principal balances of $96 million . Upon a change in our intent, the loans were transferred to held-for-sale and subsequently sold resulting in a loss on sale of $2 million during the three months ended March 31, 2016 , which is recorded in net loss on sale of assets on the Consolidated Statements of Operations. The loans sold also resulted in a charge-off of $6 million during the three months ended March 31, 2016 . Also, during the three months ended March 31, 2016 , we sold performing residential first mortgage loans with unpaid principal balances of $787 million . Upon a change in our intent, the loans were transferred to held-for-sale and subsequently sold resulting in a gain of $9 million , which is recorded in net gain on loan sales on the Consolidated Statements of Operations. During the three months ended March 31, 2015 , we re-measured the specifically identified reserve relating to the troubled debt restructured loans, resulting in a $36 million reduction in reserve based on a change in expected future cash flows. During the three months ended March 31, 2015 , we changed our intent to hold these loans for investment and instead decided to hold these loans for sale. The loans for which the intent changed had an approximate unpaid principal balance of $331 million , including approximately $291 million of troubled debt restructured residential first mortgage loans, and $30 million in specifically identified reserves at the time this intent was changed. These loans were transferred to loans held-for-sale and subsequently sold. During the three months ended March 31, 2016 , we purchased jumbo residential first mortgage loans with an unpaid principal balance of $147 million . We have pledged certain loans held-for-investment, loans held-for-sale, and loans with government guarantees to collateralize lines of credit and/or borrowings with the Federal Reserve Bank of Chicago and the Federal Home Loan Bank of Indianapolis. At March 31, 2016 and December 31, 2015 , we pledged $5.3 billion and $5.8 billion , respectively. Allowance for Loan Losses We determine the appropriate level of the allowance on at least a quarterly basis. Refer to Note 1, "Description of Business, Basis of Presentation, and Summary of Significant Accounting Policies" to the consolidated financial statements in the Annual Report on Form 10-K for the year ended December 31, 2015, for a description of the methodology. The allowance for loan losses, other than for loans that have been identified for individual evaluation for impairment, is determined on a loan pool basis by grouping loan types with similar risk characteristics to determine our best estimate of incurred losses. The allowance for loan losses by class of loan are summarized in the following table: Residential First Mortgage Second Mortgage HELOC Other Consumer Commercial Real Estate Commercial and Industrial Warehouse Lending Total (Dollars in millions) Three Months Ended March 31, 2016 Beginning balance allowance for loan losses $ 116 $ 11 $ 21 $ 2 $ 18 $ 13 $ 6 $ 187 Charge-offs (1) (11 ) (1 ) (1 ) (1 ) — — — (14 ) Recoveries — — 1 1 — — — 2 (Benefit) provision (10 ) — (1 ) — 1 (3 ) — (13 ) Ending balance allowance for loan losses $ 95 $ 10 $ 20 $ 2 $ 19 $ 10 $ 6 $ 162 Three Months Ended March 31, 2015 Beginning balance allowance for loan losses $ 234 $ 12 $ 19 $ 1 $ 17 $ 11 $ 3 $ 297 Charge-offs (1) (40 ) (1 ) (1 ) (1 ) — — — (43 ) Recoveries — — — 1 2 — — 3 (Benefit) provision (6 ) 1 3 (1 ) (3 ) 1 1 (4 ) Ending balance allowance for loan losses $ 188 $ 12 $ 21 $ — $ 16 $ 12 $ 4 $ 253 (1) Includes charge-offs of $6 million and $36 million related to the sale or transfer of loans during the three months ended March 31, 2016 and March 31, 2015 , respectively. The loans held-for-investment and allowance for loan losses by class of loan is summarized in the following table: Residential First Mortgage Second Mortgage HELOC Other Consumer Commercial Real Estate Commercial and Industrial Warehouse Lending Total (Dollars in millions) March 31, 2016 Loans held-for-investment Individually evaluated $ 47 $ 28 $ 4 $ — $ — $ 1 $ — $ 80 Collectively evaluated (1) 2,357 60 307 31 851 570 1,282 5,458 Total loans $ 2,404 $ 88 $ 311 $ 31 $ 851 $ 571 $ 1,282 $ 5,538 Allowance for loan losses Individually evaluated $ 9 $ 5 $ 2 $ — $ — $ — $ — $ 16 Collectively evaluated (1) 86 5 18 2 19 10 6 146 Total allowance for loan losses $ 95 $ 10 $ 20 $ 2 $ 19 $ 10 $ 6 $ 162 December 31, 2015 Loans held-for-investment Individually evaluated $ 87 $ 28 $ 3 $ — $ — $ 2 $ — $ 120 Collectively evaluated (1) 3,007 65 318 31 814 550 1,336 6,121 Total loans $ 3,094 $ 93 $ 321 $ 31 $ 814 $ 552 $ 1,336 $ 6,241 Allowance for loan losses Individually evaluated $ 12 $ 6 $ 1 $ 1 $ — $ — $ — $ 20 Collectively evaluated (1) 104 5 20 1 18 13 6 167 Total allowance for loan losses $ 116 $ 11 $ 21 $ 2 $ 18 $ 13 $ 6 $ 187 (1) Excludes loans carried under the fair value option. The following table sets forth the loans held-for-investment aging analysis as of March 31, 2016 and December 31, 2015 , of past due and current loans: 30-59 Days Past Due 60-89 Days Past Due 90 Days or Greater Past Due (1) Total Past Due Current Total Investment Loans (Dollars in millions) March 31, 2016 Consumer loans Residential first mortgage $ 5 $ 2 $ 41 $ 48 $ 2,362 $ 2,410 Second mortgage 1 — 2 3 126 129 HELOC 2 1 9 12 354 366 Other — — — — 31 31 Total consumer loans 8 3 52 63 2,873 2,936 Commercial loans Commercial real estate — — — — 851 851 Commercial and industrial — — 1 1 570 571 Warehouse lending — — — — 1,282 1,282 Total commercial loans — — 1 1 2,703 2,704 Total loans (2) $ 8 $ 3 $ 53 $ 64 $ 5,576 $ 5,640 December 31, 2015 Consumer loans Residential first mortgage $ 7 $ 3 $ 53 $ 63 $ 3,037 $ 3,100 Second mortgage — — 2 2 133 135 HELOC 2 1 9 12 372 384 Other 1 — — 1 30 31 Total consumer loans 10 4 64 78 3,572 3,650 Commercial loans Commercial real estate — — — — 814 814 Commercial and industrial — — 2 2 550 552 Warehouse lending — — — — 1,336 1,336 Total commercial loans — — 2 2 2,700 2,702 Total loans (2) $ 10 $ 4 $ 66 $ 80 $ 6,272 $ 6,352 (1) Includes loans that are less than 90 days past due, which continue to be placed on nonaccrual. (2) Includes $11 million and $10 million of loans 90 days or greater past due accounted for under the fair value option at March 31, 2016 and December 31, 2015 , respectively. 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 we become 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. Interest income is recognized on nonaccrual loans using a cash basis method. Interest that would have been accrued on impaired loans totaled approximately $1 million during both the three months ended March 31, 2016 and the three months ended March 31, 2015 . At March 31, 2016 and December 31, 2015 , we had no loans 90 days past due and still accruing. Troubled Debt Restructuring We may modify certain loans in both consumer and commercial loan portfolios to retain customers or to maximize collection of the outstanding loan balance. We have programs designed to assist borrowers by extending payment dates or reducing the borrower's contractual payments. All loan modifications are made on a case-by-case basis. Our standards relating to loan modifications consider, among other factors, minimum verified income requirements, cash flow analysis, and collateral valuations. TDRs result in those instances in which a borrower demonstrates financial difficulty and for which a concession has been granted, which includes reductions of interest rate, extensions of amortization period, principal and/or interest forgiveness and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral. These loans are classified as nonperforming TDRs if the loan was nonperforming prior to the restructuring, or based upon the results of a contemporaneous credit evaluation. Such loans will continue on nonaccrual status until the borrower has established a willingness and ability to make the restructured payments for at least six months, after which they will begin to accrue interest. The following table provides a summary of TDRs outstanding by type and performing status: TDRs Performing Nonperforming Total March 31, 2016 (Dollars in millions) Consumer loans Residential first mortgage $ 21 $ 16 $ 37 Second mortgage 32 1 33 HELOC 22 8 30 Total consumer loans 75 25 100 Commercial loans Commercial and industrial — 1 1 Total commercial loans — 1 1 Total TDRs (1)(2) $ 75 $ 26 $ 101 December 31, 2015 Consumer loans Residential first mortgage $ 49 $ 27 $ 76 Second mortgage 32 1 33 HELOC 20 7 27 Total TDRs (1)(2) $ 101 $ 35 $ 136 (1) The allowance for loan losses on consumer TDR loans totaled $12 million and $15 million at March 31, 2016 and December 31, 2015 , respectively. (2) Includes $33 million and $32 million of TDR loans accounted for under the fair value option at March 31, 2016 and December 31, 2015 , respectively. Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, but may give rise to potential incremental losses. We measure impairments using a discounted cash flow method for performing TDRs and measure impairment based on collateral values for re-defaulted TDRs. The following table provides a summary of newly modified TDRs during the three months ended March 31, 2016 and 2015 .

Descriptions of our internal risk ratings as they relate to credit quality follow the ratings used by the U.S. bank regulatory agencies as listed below. Pass. Pass assets are not impaired nor do they have any known deficiencies that could impact the quality of the asset. Watch. Watch assets are defined as pass rated assets that exhibit elevated risk characteristics or other factors that deserve management’s close attention and increased monitoring. However, the asset does not exhibit a potential or well-defined weakness that would warrant a downgrade to criticized or adverse classification. Special mention. Assets identified as special mention possess credit deficiencies or potential weaknesses deserving management's close attention. Special mention assets have a potential weakness or pose an unwarranted financial risk that, if not corrected, could weaken the assets and increase risk in the future. Special mention assets are criticized, but do not expose an institution to sufficient risk to warrant adverse classification. Substandard . Assets identified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. For HELOC loans and other consumer loans, we evaluate credit quality based on the aging and status of payment activity and any other known credit characteristics that call into question full repayment of the asset. Nonperforming loans are classified as either substandard, doubtful or loss. Doubtful . An asset classified as doubtful has all the weaknesses inherent in one classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. A doubtful asset has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral, and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Because of high probability of loss, non-accrual accounting treatment is required for doubtful assets. Loss. An asset classified as loss is considered uncollectible and of such little value that the continuance as bankable asset is not warranted. This classification does not mean that an asset has absolutely no recovery or salvage value, but, rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future. Commercial Loans Management conducts periodic examinations which serve as an independent verification of the accuracy of the ratings assigned. Loan grades are based on different factors within the borrowing relationship: entity sales, debt service coverage, debt/total net worth, liquidity, balance sheet and income statement trends, management experience, business stability, financing structure of the deal, and financial reporting requirements. The underlying collateral is also rated based on the specific type of collateral and corresponding LTV. The combination of the borrower and collateral risk ratings result in the final rating for the borrowing relationship. Consumer Loans The same rating principles are used for consumer and commercial loans, but the principles are applied differently for consumer loans. Consumer loans consist of open and closed end loans extended to individuals for household, family, and other personal expenditures, and includes consumer loans, loans to individuals secured by their personal residence, including first mortgage, home equity, and home improvement loans. Because consumer loans are usually relatively small-balance, homogeneous exposures, consumer loans are rated primarily on payment performance. Payment performance is a proxy for the strength of repayment capacity and loans are generally classified based on their payment status rather than by an individual review of each loan. In accordance with regulatory guidance, we assign risk ratings to consumer loans in the following manner: • Consumer loans are classified as Watch once the loan becomes 60 days past due. • Open and closed-end consumer loans 90 days or more past due are classified Substandard.

Disclosure of Transfer of Securitizations or Asset-backed Financing Financial Assets Accounted for as Sale [Abstract]
Variable Interest Entities (VIEs)	Variable Interest Entities ("VIEs") In 2015, we executed clean-up calls of the FSTAR 2005-1 and FSTAR 2006-2 long-term debt associated with the HELOC securitization trusts. The transactions resulted in cash payments of $52 million to the debt bondholders during the year ended December 31, 2015 . After payment of the debt, the FSTAR 2005-1 and FSTAR 2006-2 HELOC securitization trusts were dissolved and we no longer have any consolidated VIEs as of December 31, 2015 . We have a continuing involvement, but are not the primary beneficiary for one unconsolidated VIE related to the FSTAR 2007-1 mortgage securitization trust. In accordance with the settlement agreement with MBIA, there is no further recourse to us related to FSTAR 2007-1, unless MBIA fails to meet their obligations. At March 31, 2016 and December 31, 2015 , the FSTAR 2007-1 mortgage securitization trust included 2,904 loans and 3,061 loans, respectively, with an aggregate principal balance of $109 million and $117 million , respectively.

Mortgage Servicing Rights

Transfers and Servicing [Abstract]
Mortgage Servicing Rights	Mortgage Servicing Rights We have investments in mortgage servicing rights ("MSRs") resulting from the sale of loans to the secondary market and retaining the servicing. The primary risk associated with MSRs is the potential change in value as a result of higher than anticipated prepayments due to loan refinancing prompted, in part, by declining interest rates or government intervention. Conversely, these assets generally increase in value in a rising interest rate environment to the extent that prepayments are slower than anticipated. We also utilize derivatives as economic hedges to offset changes in the fair value of the MSRs resulting from the actual or anticipated changes in prepayments stemming from changing interest rate environments. Our portfolio of MSRs is highly sensitive to movements in interest rates. There is also a risk of valuation decline due to higher than expected increases in default rates, which we do not believe can be effectively hedged. See Note 8 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: Three Months Ended March 31, 2016 2015 (Dollars in millions) Balance at beginning of period $ 296 $ 258 Additions from loans sold with servicing retained 57 68 Reductions from sales (24 ) (21 ) Changes in fair value due to (1) Decrease in MSR due to pay-offs, pay-downs and run-off (11 ) (15 ) Changes in estimates of fair value (2) (37 ) (11 ) Fair value of MSRs at end of period $ 281 $ 279 (1) Changes in fair value are included within net loss on mortgage servicing asset on the Consolidated Statements of Operations. (2) Represents estimated MSR value change resulting primarily from market-driven changes in interest rates. See Note 19 of the Notes to the Consolidated Financial Statements, herein, for additional fair value disclosures relating to mortgage servicing rights. The following table summarizes income and fees associated with the mortgage servicing rights: Three Months Ended March 31, 2016 2015 (Dollars in millions) Income on mortgage servicing rights Servicing fees, ancillary income and late fees (1) $ 17 $ 17 Fair value adjustments (48 ) (26 ) Gain on MSR derivatives (2) 26 9 Net transaction costs (1 ) (2 ) Total loss, included in net return on mortgage servicing rights $ (6 ) $ (2 ) (1) Servicing fees are recorded on the accrual basis. Ancillary income and late fees are recorded on a cash basis. (2) Changes in the derivatives utilized as economic hedges to offset changes in fair value of the MSRs. Contractual servicing and subservicing fees . Contractual servicing and subservicing fees, including late fees and other ancillary income are presented below. Contractual servicing fees are included within net return on mortgage servicing rights on the Consolidated Statements of Operations. Contractual subservicing fees including late fees and other ancillary income are included within loan administration income on the Consolidated Statements of Operations. Subservicing fee income is recorded for fees earned, net of third party subservicing costs, for loans subserviced. The following table summarizes income and fees associated with the mortgage loans subserviced: Three Months Ended March 31, 2016 2015 (Dollars in millions) Income on mortgage loans subserviced Servicing fees, ancillary income and late fees (1) $ 8 $ 8 Other servicing charges (2 ) (4 ) Total income, included in loan administration $ 6 $ 4 (1) Servicing fees are recorded on the accrual basis. Ancillary income and late fees are recorded on cash basis. The following table summarizes the hypothetical effect on the fair value of servicing rights carried at fair value using adverse changes of 10 percent and 20 percent to the weighted average of certain significant assumptions used in valuing these assets: March 31, 2016 December 31, 2015 Fair value due to Fair value due to Actual 10% adverse change 20% adverse change Actual 10% adverse change 20% adverse change (Dollars in millions) Option adjusted spread 8.18 % $ 273 $ 264 8.24 % $ 287 $ 279 Constant prepayment rate 15.21 % 268 257 12.63 % 285 275 Weighted average cost to service per loan $ 71.68 277 273 $ 71.86 292 288 The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. To isolate the effect of the specified change, the fair value shock analysis is consistent with the identified adverse change, while holding all other assumptions constant. In practice, a change in one assumption generally impacts other assumptions, which may either magnify or counteract the effect of the change.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments Derivative financial instruments are recorded at fair value in other assets and other liabilities on the Consolidated Statements of Financial Condition after taking into account the effects of legally enforceable bilateral collateral and master netting agreements. The Company is exposed to non-performance risk by the counterparties to its various derivative financial instruments. The Company believes that the non-performance risk inherent in all its derivative contracts is minimal based on credit standards and the collateral provisions of the derivative agreements. A majority of the Company’s derivatives are centrally cleared through a Central Counterparty Clearing House or consist of residential mortgage interest rate lock commitments further limiting non-performance risk. Derivatives not designated as hedging instruments: The Company maintains a derivative portfolio of interest rate swaps, futures and forward commitments used to manage exposure to changes in interest rates, MSR asset values and to meet the needs of customers. The Company also enters into interest rate lock commitments, which are commitments to originate mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. Market risk on interest rate lock commitments and mortgage loans held-for-sale is managed using corresponding forward sale commitments. Changes in fair value of derivatives not designated as hedging instruments are recognized in the Consolidated Statements of Income. Derivatives designated as hedging instruments: We use interest rate swaps to hedge the forecasted cash flows from our underlying variable-rate Federal Home Loan Bank (FHLB) advances in a qualifying cash flow hedge accounting relationship. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense in the same period in which the hedge transaction is recognized in earnings. At March 31, 2016 , we had $31 million (net-of-tax) recorded of unrealized losses on derivatives classified as cash flow hedges recorded in other comprehensive income (loss) related to derivatives classified as cash flow hedges, compared to $3 million at December 31, 2015 . The estimated amount to be reclassified from other comprehensive income into earnings during the next 12 months represents $9 million of losses (net-of-tax). Derivatives that are designated in hedging relationships are assessed for effectiveness using regression analysis at inception and throughout the hedge period. All cash flow hedges were highly effective as of March 31, 2016 . Cash flows and the profit impact associated with designated hedges are reported in the same category as the underlying hedged item.

We settled $375 million in long-term fixed rate Federal Home Loan Bank advances during the fourth quarter 2015, which resulted in a gain on extinguishment of debt of $3 million , included in other noninterest income. At March 31, 2016 , we had the authority and approval from the Federal Home Loan Bank to utilize a line of credit of up to $7.0 billion and we may access that line to the extent that collateral is provided. At March 31, 2016 , we had $2.9 billion of advances outstanding and an additional $0.7 billion of collateralized borrowing capacity available at Federal Home Loan Bank. The advances can be collateralized by non-delinquent single-family residential first mortgage loans, loans with government guarantees, certain other loans and investment securities. At March 31, 2016 , $1.0 billion of the outstanding advances were adjustable rate based on the three -month LIBOR index. Interest rates on these advances reset every three months and the advances may be prepaid without penalty, with notification at scheduled three month intervals after an initial 12 month lockout period. The outstanding advances included $1.0 billion in a cash flow hedge relationship as discussed in Note 8 of the Notes to the Consolidated Financial Statements, herein.

The notes held by each trust are the sole assets of that trust. The trust preferred securities outstanding are junior subordinated notes which are callable by us. Interest is payable quarterly at a rate equal to the interest rate being earned by the trust on the notes held by the trusts; however, we may defer interest payments for up to 20 quarters without default or penalty. In January 2012, we exercised our contractual rights to defer interest payments with respect to trust preferred securities. The payments are periodically evaluated and will be reinstated when appropriate, subject to the provisions of our Supervisory Agreement and Consent Order. At March 31, 2016 , we have deferred for 17 quarters and have $29 million accrued for these deferred interest payments.

Warrants	Warrants May Investor Warrant We granted warrants (the "May Investor Warrants") to the May Investors on January 30, 2009 under anti-dilution provisions applicable to certain investors (the "May Investors") in our May 2008 private placement capital raise. For the three months ended March 31, 2016 , there were no May Investor Warrants exercised. The May Investors held warrants to purchase 615,962 shares at an exercise price of $10.00 at March 31, 2016 . The May Investor Warrants do not meet the definition of a contract that is indexed to our own stock under U.S. GAAP. Therefore, the May Investor Warrants are classified as "other liabilities" on the Consolidated Statements of Financial Condition and are measured at fair value. Warrant liabilities are valued using a binomial lattice model and are classified within Level 2 of the valuation hierarchy. Significant observable inputs include share price, expected volatility, a risk free rate and an expected life. At March 31, 2016 and December 31, 2015 , the liability from May Investors Warrants amounted to $7 million and $8 million , respectively. Warrant liabilities are reported in "other liabilities" on the Consolidated Statements of Financial Condition. See Note 19 of the Notes to the Consolidated Financial Statements, herein, for additional recurring fair value disclosures. The warrants are accounted for under the equity method. TARP Warrant On January 30, 2009, we 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 645,138 shares of Common Stock at an exercise price of $62.00 per share (the "Warrant") for $267 million . The Series C Preferred Stock qualifies as Tier 1 capital and currently pays cumulative dividends quarterly at a rate of 9 percent per annum. The Warrant is exercisable through 2019.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share, excluding dilution, is computed by dividing earnings available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised and converted into common stock or resulted in the issuance of common stock that could then share in our earnings. The following table sets forth the computation of basic and diluted earnings per share of common stock: Three Months Ended March 31, 2016 2015 (Dollars in millions, except share data) Net income $ 39 $ 32 Deferred cumulative preferred stock dividends (8 ) (7 ) Net income applicable to common stock $ 31 $ 25 Weighted average shares Weighted average common shares outstanding 56,513,715 56,385,454 Effect of dilutive securities May Investor warrants (1) 305,219 232,474 Stock-based awards 782,050 157,111 Weighted average diluted common shares 57,600,984 56,775,039 Earnings per common share Basic earnings per common share $ 0.56 $ 0.43 Effect of dilutive securities May Investor warrants (1) — — Stock-based awards (0.02 ) — Diluted earnings per share $ 0.54 $ 0.43 (1) Exercise price of $10.00 per share and a fair value of $7 million at March 31, 2016 . Under the terms of the Series C Preferred Stock we may defer dividend payments. We elected to defer dividend payments beginning with the February 2012 dividend. Although not included in quarterly net income from continuing operations, the deferral still impacts net income applicable to common stock for the purpose of calculating earnings per share, as shown above. The cumulative amount in arrears as of March 31, 2016 is $94 million .

Regulatory Capital Requirements [Abstract]
Regulatory Matters	Regulatory Matters Regulatory Capital We, along with the Bank, must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by regulators that could have a material effect on the Consolidated Financial Statements. On January 1, 2015, the Basel III rules became effective and include transition provisions through 2018. To be categorized as "well-capitalized," the Company and the Bank must maintain minimum tangible capital, Tier 1 capital, common equity Tier 1, and total capital ratios as set forth in the table below. We, along with the Bank, are considered "well-capitalized" at both March 31, 2016 and December 31, 2015 . There have been no conditions or events that management believes have changed our or the Bank’s category.

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings, Contingencies and Commitments	Legal Proceedings, Contingencies and Commitments Legal Proceedings We and our subsidiaries are subject to various pending or threatened legal proceedings arising out of the normal course of business operations. In addition, the Bank is routinely named in civil actions throughout the country by borrowers and former borrowers relating to the origination, purchase, sale, and servicing of mortgage loans. From time to time, governmental agencies also conduct investigations or examinations of various mortgage-related practices of the Bank. In the course of such investigations or examinations, the Bank cooperates with such agencies and provides information as requested. We assess the liabilities and loss contingencies in connection with such pending or threatened legal and regulatory proceedings on at least a quarterly basis and establish accruals when we believe it is probable that a loss may be incurred and that the amount of such loss can be reasonably estimated. Once established, litigation accruals are adjusted, as appropriate, in light of additional information. Management does not believe that the amount of any reasonably possible losses in excess of any amounts accrued with respect to ongoing proceedings or any other known claims will be material to our financial statements, or that the ultimate outcome of these actions will have a material adverse effect on our financial condition, results of operations or cash flows. DOJ litigation settlement We elected the fair value option to account for the liability representing the obligation to make future additional payments under the DOJ litigation settlement. The executed settlement agreement with the DOJ establishes a legally enforceable contract with a stipulated payment plan that meets the definition of a financial liability. At March 31, 2016 the remaining future payments totaled $118 million for which we used a discounted cash flow model to estimate the current fair value. The model utilizes estimates including our forecasts of net income, balance sheet and capital levels and considers multiple scenarios and possible outcomes as a result of the uncertainty inherent in those inputs which impact the estimated timing of the additional payments. These scenarios are probability weighted and consider the view of a market participant to estimate the fair value of the liability. The fair value of the DOJ litigation settlement liability was $84 million at both March 31, 2016 and December 31, 2015 , respectively. At both March 31, 2016 and December 31, 2015 , excluding the fair value liability relating to the DOJ litigation settlement, our total accrual for contingent liabilities was $2 million . Commitments A summary of the contractual amount of significant commitments is as follows: March 31, 2016 December 31, 2015 (Dollars in millions) Commitments to extend credit Mortgage loans interest-rate lock commitments $ 5,710 $ 3,792 HELOC commitments 166 150 Other consumer commitments 31 22 Warehouse loan commitments 973 871 Standby and commercial letters of credit 13 13 Commercial and industrial commitments 157 151 Other commercial commitments 683 497 Commitments to extend credit are agreements to lend. Since many of these commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements. Commitments generally have fixed expiration dates or other termination clauses. We evaluate each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by us, upon extension of credit is based on management's credit evaluation of the counterparties. We enter into mortgage interest-rate lock commitments with our customers. These commitments are considered to be derivative instruments and changes in the fair value of these commitments are recorded in the Consolidated Statements of Financial Condition in other assets. Further discussion on derivative instruments is included in Note 8 of the Notes to the Consolidated Financial Statements, herein. We have unfunded commitments under our contractual arrangement with the HELOC borrowers. Commitments to extend, originate or purchase credit are primarily lines of credit to consumers and have specified rates and maturity dates. Many of these commitments also have adverse change clauses, which allow us to cancel the commitment due to deterioration in the borrowers’ creditworthiness. Other consumer commitments are conditional commitments issued to accommodate the financial needs of customers. The commitments are under various terms to lend funds to consumers, which include revolving credit agreements, term loan commitments and short-term borrowing agreements. Warehouse loan commitments are lines of credit provided to mortgage originators to fund loans they originate and then sell. The proceeds of the sale of the loans are used to repay the draw on the line used to fund the loans. Standby and commercial letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party, while commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and the third party. Commercial and industrial and other commercial commitments are conditional commitments issued under various terms to lend funds to business and other entities. These commitments include revolving credit agreements, term loan commitments and short-term borrowing agreements. Many of these loan commitments have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of these commitments are expected to expire without being funded, the total commitment amounts do not necessarily represent future liquidity requirements. These instruments involve, to varying degrees, elements of credit and interest rate risk beyond the amount recognized on the Consolidated Statements of Financial Condition. Our exposure to credit losses in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. We utilize the same credit policies in making commitments and conditional obligations as we do for balance sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is not a violation of any condition established in the contract. We maintain a reserve for the estimate of probable credit losses inherent in unfunded commitments to extend credit. Unfunded commitments to extend credit include unfunded loans with available balances, new commitments to lend that are not yet funded, and standby and commercial letters of credit. The balance of $3 million and $2 million for March 31, 2016 and December 31, 2015 , respectively, is reflected in other liabilities on the Consolidated Statements of Financial Condition.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We utilize fair value measurements to record or disclose the fair value on certain assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability through an orderly transaction between market participants at the measurement date. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation models rely on market-based parameters when available, such as interest rate yield curves or credit spreads. Unobservable inputs may be based on management's judgment, assumptions and estimates related to credit quality, our future earnings, interest rates and other relevant inputs. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. Valuation Hierarchy U.S. GAAP establishes a three-level valuation hierarchy for disclosure of fair value measurements. The hierarchy is based on the transparency of the inputs used in the valuation process with the highest priority given to quoted prices available in active markets and the lowest priority to unobservable inputs where no active market exists, as discussed below. Level 1 - Quoted prices (unadjusted) for identical assets or liabilities in active markets in which we can participate as of the measurement date; Level 2 - Quoted prices for similar instruments in active markets, and other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument; and Level 3 - Unobservable inputs that reflect our own assumptions about the assumptions that market participants would use in pricing 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. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy. Assets Investment securities available-for-sale. These securities are comprised of U.S. government sponsored agencies and municipal obligations. We measure fair value using prices obtained from pricing services. A review is performed on the security prices received from the pricing services, which includes discussion and analysis of the inputs used by the pricing services to value our securities and comparisons to independent pricing. Where possible, fair values are generated using market inputs including quoted prices (the closing price in an exchange market), bid prices (the price at which a buyer stands ready to purchase), and other market information. For fixed income securities that are not actively traded, the pricing services use alternative methods to determine fair value for the securities, including quotes for similar fixed-income securities, matrix pricing, discounted cash flow using benchmark curves or other factors to determine fair value. Investment securities are classified within level 2 of the valuation hierarchy. Loans held-for-sale. We generally estimate the fair value of loans held-for-sale based on quoted market prices for securities backed by similar types of loans. Where quoted market prices were available, such market prices were utilized as estimates for fair values. Otherwise, the fair value of loans was computed by discounting cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. These loans are classified as level 2. Loans held-for-investment. Loans held-for-investment are generally recorded at amortized cost. Such loans are not recorded at fair value on a recurring basis. However, from time to time, a loan becomes impaired when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Once a loan is identified as impaired, the fair value of the impaired loan is estimated using one of several methods, including collateral value less costs to sell, market value of similar debt, or discounted cash flows. The fair value of the underlying collateral is determined, where possible, using market prices derived from appraisals or market evaluations which are considered a nonrecurring level 3 valuation. Fair value may also be measured using the present value of expected cash flows discounted at the loan's effective interest rate. Loans held-for-investment that are recorded at fair value on a recurring basis are loans that were previously recorded as loans held-for-sale but subsequently transferred to the held-for-investment category. As we elected the fair value option for the held-for-sale loans, they continue to be reported at fair value and measured consistent with the level 2 methodology for loans held-for-sale. Certain HELOC loans have been recorded in the Consolidated Financial Statement as loans held-for-investment at fair value. We record these loans as a recurring level 3 valuation. Also included in loans held-for-investment are the second mortgage loans which are carried at fair value and valued using a discounted estimated net future cash flow model and are classified within the level 3 valuation hierarchy as the model utilizes significant inputs which are unobservable. Repossessed assets. Repossessed assets are measured and reported at fair value through a charge-off to the allowance for loan losses based upon the fair value of the repossessed asset. The fair value of repossessed assets, upon initial recognition, are estimated using level 3 inputs based on appraisals or evaluations. The significant unobservable inputs used in the level 3 fair value measurements of our impaired loans and repossessed assets primarily relate to internal valuations or analysis. Mortgage Servicing Rights. The current market for MSRs is not sufficiently liquid to provide participants with quoted market prices. Therefore, we use an option-adjusted spread valuation approach to determine the fair value of MSRs. This approach consists of projecting servicing cash flows under multiple interest rate scenarios and discounting these cash flows using risk-adjusted discount rates. 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 our internal valuation model. In certain circumstances, based on the probability of the completion of a sale of MSRs pursuant to a bona-fide purchase offer, we consider 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. Due to the nature of the valuation inputs, MSRs are classified within level 3 of the valuation hierarchy. Derivative financial instruments. Certain classes of derivative contracts are listed on an exchange and are actively traded, and they are therefore classified within level 1 of the valuation hierarchy. These include U.S. Treasury futures and U.S. Treasury options. Our forward loan sale commitments, swap futures and interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable and are classified within level 2 of the valuation hierarchy. Rate lock commitments are valued using internal models with significant unobservable market parameters and therefore are classified within level 3 of the valuation hierarchy. We assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and determined that the credit valuation adjustments were not significant to the overall valuation of our derivatives. We use interest rate swaps to hedge the forecasted cash flows from our underlying variable-rate FHLB advances in a qualifying cash flow hedge accounting relationship. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense along with the debt interest expense in the same period in which the identified hedge transaction is recognized in earnings. The derivatives are reported in either other assets or other liabilities on the Consolidated Statements of Financial Condition. Liabilities Warrants. 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. Litigation settlement. Upon settlement of the DOJ litigation settlement, we elected the fair value option to account for the liability representing the remaining future payments. As of March 31, 2016 the fair value totaled $84 million , using a discount rate of 7.3 percent for which we use a discounted cash flow model to determine the current fair value. The model utilizes our forecast and considers multiple scenarios including possible outcomes that impact the timing of the additional payments which are discounted using a risk free rate adjusted for nonperformance risk that represents our credit risk. These scenarios are probability weighted and consider the view of an independent market participant to estimate the most likely fair value of the liability. The liability is classified within level 3 of the valuation hierarchy as the projections of earnings and growth rate and other assumptions are unobservable inputs which affect the estimated timing of the cash flow payments. We consider factors which could affect those projections from the perspective of a market participant, which is incorporated into the assessment of fair value. The litigation settlement is included in other liabilities on the Consolidated Statements of Financial Condition and changes in the fair value of the litigation settlement will be recorded each quarter in other noninterest expense on the Consolidated Statements of Operations. Assets and liabilities measured at fair value on a recurring basis The following tables present the financial instruments carried at fair value as of March 31, 2016 and December 31, 2015 , by caption on the Consolidated Statement of Financial Condition and by level in the valuation hierarchy (as described above): Level 1 Level 2 Level 3 Total Fair Value March 31, 2016 (Dollars in millions) Investment securities available-for-sale Agency - Commercial $ — $ 767 $ — $ 767 Agency - Residential — 507 — 507 Municipal obligations — 40 — 40 Loans held-for-sale Residential first mortgage loans — 2,571 — 2,571 Loans held-for-investment Residential first mortgage loans — 7 — 7 Second mortgage loans — — 40 40 HELOC loans — — 55 55 Mortgage servicing rights — — 281 281 Derivative assets Rate lock commitments — — 61 61 U.S. Treasury, swap and euro dollar futures 2 — — 2 Mortgage backed securities forwards — 1 — 1 Interest rate swaps and swaptions — 56 — 56 Total derivative assets 2 57 61 120 Total assets at fair value $ 2 $ 3,949 $ 437 $ 4,388 Derivative liabilities U.S. Treasury, swap and euro dollar futures $ (1 ) $ — $ — $ (1 ) Interest rate swap on FHLB advances — (47 ) — (47 ) Mortgage backed securities forwards — (29 ) — (29 ) Interest rate swaps and swaptions — (14 ) — (14 ) Total derivative liabilities (1 ) (90 ) — (91 ) Warrant liabilities — (7 ) — (7 ) DOJ litigation settlement — — (84 ) (84 ) Total liabilities at fair value $ (1 ) $ (97 ) $ (84 ) $ (182 ) Level 1 Level 2 Level 3 Total Fair Value December 31, 2015 (Dollars in millions) Investment securities available-for-sale Agency - Commercial $ — $ 766 $ — $ 766 Agency - Residential — 514 — 514 Municipal obligations — 14 — 14 Loans held-for-sale Residential first mortgage loans — 2,541 — 2,541 Loans held-for-investment Residential first mortgage loans — 6 — 6 Second mortgage loans — — 42 42 HELOC loans — — 64 64 Mortgage servicing rights — — 296 296 Derivative assets Rate lock commitments — — 26 26 Mortgage backed securities forwards — 7 — 7 Interest rate swaps and swaptions — 25 — 25 Total derivative assets — 32 26 58 Total assets at fair value $ — $ 3,873 $ 428 $ 4,301 Derivative liabilities U.S. Treasury, swap and euro dollar futures $ (1 ) $ — $ — $ (1 ) Mortgage backed securities forwards — (6 ) — (6 ) Interest rate swap on FHLB advances — (4 ) — (4 ) Interest rate swaps — (7 ) — (7 ) Total derivative liabilities (1 ) (17 ) — (18 ) Warrant liabilities — (8 ) — (8 ) DOJ litigation settlement — — (84 ) (84 ) Total liabilities at fair value $ (1 ) $ (25 ) $ (84 ) $ (110 ) We had no transfers of assets or liabilities recorded at fair value between fair value levels during the three months ended March 31, 2016 and 2015 . We utilized US Treasury future, forward agency and loan sales and interest rate swaps to manage the risk associated with mortgage servicing rights and rate lock commitments. The assets and/or liabilities transferred are valued at the end of the period. Gains and losses for individual lines in the tables do not reflect the effect of our risk management activities related to such level 3 instruments. Fair value measurements using significant unobservable inputs The tables below include a roll forward of the Consolidated Statement of Financial Condition amounts for the three months ended March 31, 2016 and 2015 (including the change in fair value) for financial instruments classified by us within level 3 of the valuation hierarchy: Recorded in Earnings Recorded in OCI Three Months Ended March 31, 2016 Balance at Beginning of Period Total Unrealized Gains / (Losses) Total Realized Gains / (Losses) Total Unrealized Gains / (Losses) Purchases / Originations Sales Settlements Balance at End of Period Changes in Unrealized Gains / (Losses) Held at End of Period Assets (Dollars in millions) Loans held-for-investment Second mortgage loans $ 42 $ 1 $ — $ — $ — $ — $ (3 ) $ 40 $ 1 HELOC loans 64 — — — — — (9 ) 55 — Mortgage servicing rights 296 (48 ) — — 57 (24 ) — 281 (32 ) Totals $ 402 $ (47 ) $ — $ — $ 57 $ (24 ) $ (12 ) $ 376 $ (31 ) Liabilities DOJ litigation settlement $ (84 ) $ — $ — $ — $ — $ — $ — $ (84 ) $ — Derivative financial instruments (net) Rate lock commitments $ 26 $ 62 $ — $ — $ 81 $ (95 ) $ (13 ) $ 61 $ 20 Three Months Ended March 31, 2015 Assets Other investments $ 100 $ — $ — $ — $ — $ — $ — $ 100 $ — Investment securities available-for-sale Municipal obligation 2 — — — — — (2 ) — — Loans held-for-investment Second mortgage loans 53 — — — — — (3 ) 50 — HELOC loans 132 (4 ) — — — — (15 ) 113 (2 ) Mortgage servicing rights 258 (26 ) — — 68 (22 ) — 278 (8 ) Totals $ 545 $ (30 ) $ — $ — $ 68 $ (22 ) $ (20 ) $ 541 $ (10 ) Liabilities Long-term debt $ (84 ) $ — $ (2 ) $ — $ — $ — $ 16 $ (70 ) $ — DOJ litigation settlement (82 ) — — — — — — (82 ) — Totals $ (166 ) $ — $ (2 ) $ — $ — $ — $ 16 $ (152 ) $ — Derivative financial instruments (net) Rate lock commitments $ 31 $ 37 $ — $ — $ 98 $ (97 ) $ (14 ) $ 55 $ 17 Totals $ 31 $ 37 $ — $ — $ 98 $ (97 ) $ (14 ) $ 55 $ 17 The following tables present the quantitative information about recurring level 3 fair value financial instruments and the fair value measurements as of March 31, 2016 and December 31, 2015 : Fair Value Valuation Technique Unobservable Input Range (Weighted Average) March 31, 2016 (Dollars in millions) Assets Second mortgage loans $ 40 Discounted cash flows Discount rate 7.2% - 10.8% (9.0%) HELOC loans $ 55 Discounted cash flows Discount rate 7.4% - 11.1% (9.2%) Mortgage servicing rights $ 281 Discounted cash flows Option adjusted spread 6.5% - 9.8% (8.2%) Liabilities DOJ litigation settlement $ (84 ) Discounted cash flows Discount rate 5.9% - 8.8% (7.3%) Derivative financial instruments Rate lock commitments $ 61 Consensus pricing Origination pull-through rate 65.0% - 97.4% (81.2%) Fair Value Valuation Technique Unobservable Input Range (Weighted Average) December 31, 2015 (Dollars in millions) Assets Second mortgage loans $ 42 Discounted cash flows Discount rate 7.2% - 10.8% (9.0%) HELOC loans $ 64 Discounted cash flows Discount rate 6.8% - 10.1% (8.4%) Mortgage servicing rights $ 296 Discounted cash flows Option adjusted spread 6.6% - 9.9% (8.2%) Liabilities DOJ litigation settlement $ (84 ) Discounted cash flows Discount rate 4.9% - 9.5% (7.2%) Derivative financial instruments Rate lock commitments $ 26 Consensus pricing Origination pull-through rate 67.6% - 101.5% (84.6%) Recurring Significant Unobservable Inputs The significant unobservable inputs used in the fair value measurement of the second mortgage loans are discount rates, constant prepayment rates, and default rates. The constant prepayment and default rates are based on a 12 month historical average. Significant increases (decreases) in the discount rate in isolation would result in a significantly lower (higher) fair value measurement. Increases (decreases) in prepay rates in isolation result in a higher (lower) fair value and increases (decreases) in default rates in isolation result in a lower (higher) fair value. The HELOC loans are valued utilizing a loan-level discounted cash flow model which projects expected cash flows given three potential outcomes: (1) paid-in-full at scheduled maturity, (2) default at scheduled maturity (foreclosure), and (3) modification at scheduled maturity into an amortizing HELOC. Loans are placed into the potential outcome buckets based on their underlying current delinquency, FICO scores and property CLTV all of which are unobservable inputs. Estimated cash flows are then discounted back using an unobservable discount rate. Loans within the HELOC portfolio contain FICO scores with a minimum of 447 , maximum of 817 , and a weighted average of 673 . For the HELOC loans, increases (decreases) in the discount rate, in isolation, would lower (higher) the fair value measurement. The significant unobservable inputs used in the fair value measurement of the MSRs are option adjusted spreads, prepayment rates, and cost to service. Significant increases (decreases) in all three assumptions in isolation would result in a significantly lower (higher) fair value measurement. Additionally, the key economic assumptions used in determining the fair value of MSRs capitalized during the three months ended March 31, 2016 and 2015 periods were as follows: Three Months Ended March 31, 2016 2015 Weighted average life (in years) 7.3 7.3 Weighted average constant prepayment rate 13.8 % 13.6 % Weighted average option adjusted spread 7.29 % 8.53 % The key economic assumptions reflected in the overall fair value of the entire portfolio of MSRs were as follows: March 31, December 31, Weighted average life (in years) 6.4 7.3 Weighted average constant prepayment rate 15.2 % 12.6 % Weighted average option adjusted spread 8.18 % 8.24 % The significant unobservable input used in the fair value measurement of the rate lock commitments is the pull through rate. The pull through rate is a statistical analysis of our actual rate lock fallout history to determine the sensitivity of the residential mortgage loan pipeline compared to interest rate changes and other deterministic values. New market prices are applied based on updated loan characteristics and new fallout ratios (i.e., the inverse of the pull through rate) are applied accordingly. Significant increases (decreases) in the pull through rate in isolation would result in a significantly higher (lower) fair value measurement. The significant unobservable input used in the fair value measurement of the DOJ litigation settlement is the discount rate. Significant increases (decreases) in the discount rate in isolation could result in a marginally lower (higher) fair value measurement. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis We also have assets that under certain conditions are subject to measurement at fair value on a nonrecurring basis. These assets are measured at the lower of cost or market and had a fair value below cost at the end of the period as summarized below: Total (1) Level 2 Level 3 (Dollars in millions) March 31, 2016 Loans held-for-sale (2) $ 7 $ 7 $ — Impaired loans held-for-investment (3) Residential first mortgage loans 16 — 16 Commercial and industrial loans 1 — 1 Repossessed assets (4) 14 — 14 Totals $ 38 $ 7 $ 31 December 31, 2015 Loans held-for-sale (2) $ 8 $ 8 $ — Impaired loans held-for-investment (3) Residential first mortgage loans 40 — 40 Commercial real estate loans 2 — 2 Repossessed assets (4) 17 — 17 Totals $ 67 $ 8 $ 59 (1) The fair values are obtained at various dates during the three months ended March 31, 2016 and the year ended December 31, 2015 , respectively. (2) We recorded less than $1 million and $1 million in fair value losses on loans held-for-sale for which we did not elect the fair value option (included in interest income on the Consolidated Statements of Operations) during the three months ended March 31, 2016 and March 31, 2015 , respectively. (3) We recorded $11 million and $4 million in fair value losses on impaired loans (included in provision (benefit) for loan losses on Consolidated Statements of Operations) during the three months ended March 31, 2016 and March 31, 2015 , respectively. (4) We recorded less than $1 million in losses related to write downs of repossessed assets based on the estimated fair value of the specific assets during the three months ended March 31, 2016 and recognized net gain of $1 million on sales of repossessed assets (both write downs and net gains/losses are included in assets resolution expense on the Consolidated Statements of Operations) during the three months ended March 31, 2016 . We recorded $1 million in losses related to write downs of repossessed assets based on the estimated fair value of the specific assets during the three months ended March 31, 2015 and recognized a net loss of zero on sales of repossessed assets during the three months ended March 31, 2015 . The following tables present the quantitative information about nonrecurring level 3 fair value financial instruments and the fair value measurements as of March 31, 2016 and December 31, 2015 : Fair Value Valuation Technique Unobservable Input Range (Weighted Average) March 31, 2016 (Dollars in millions) Impaired loans held-for-investment Residential first mortgage loans $ 16 Fair value of collateral Loss severity discount 35% - 45% (40.2%) Commercial and industrial loans $ 1 Fair value of collateral Loss severity discount 50% - 60% (55.1%) Repossessed assets $ 14 Fair value of collateral Loss severity discount 12% - 88% (57.3%) Fair Value Valuation Technique Unobservable Input Range (Weighted Average) December 31, 2015 (Dollars in millions) Impaired loans held-for-investment Residential first mortgage loans $ 40 Fair value of collateral Loss severity discount 35% - 45% (35.2%) Commercial real estate loans $ 2 Fair value of collateral Loss severity discount 45% - 55% (50.1%) Repossessed assets $ 17 Fair value of collateral Loss severity discount 16% - 100% (48.7%) Nonrecurring Significant Unobservable Inputs The significant unobservable inputs used in the fair value measurement of the impaired loans and repossessed assets are appraisals or other third-party price evaluations which incorporate measures such as recent sales prices for comparable properties. Fair Value of Financial Instruments The following table presents the carrying amount and estimated fair value of financial instruments that are carried either at fair value, cost, or amortized cost: March 31, 2016 Estimated Fair Value Carrying Value Total Level 1 Level 2 Level 3 (Dollars in millions) Assets Cash and cash equivalents $ 724 $ 724 $ 724 $ — $ — Investment securities 2,567 2,584 — 2,584 — Loans held-for-sale 2,591 2,593 — 2,593 — Loans with government guarantees 462 447 — 447 — Loans held-for-investment, net 5,478 5,442 — 7 5,435 Repossessed assets 14 14 — — 14 Federal Home Loan Bank stock 172 172 — 172 — Mortgage servicing rights 281 281 — — 281 Bank owned life insurance 265 265 — 265 — Other assets, foreclosure claims 202 202 — 202 — Derivative financial instruments, assets 120 120 2 57 61 Liabilities Retail deposits Demand deposits and savings accounts (5,024 ) (4,790 ) — (4,790 ) — Certificates of deposit (905 ) (918 ) — (918 ) — Government deposits (1,112 ) (1,098 ) — (1,098 ) — Company controlled deposits (1,428 ) (1,370 ) — (1,370 ) — Federal Home Loan Bank advances (2,875 ) (2,865 ) — (2,865 ) — Other long-term debt (247 ) (81 ) — (81 ) — Warrant liabilities (7 ) (7 ) — (7 ) — DOJ litigation settlement (84 ) (84 ) — — (84 ) Derivative financial instruments, liabilities (91 ) (91 ) (1 ) (90 ) — December 31, 2015 Estimated Fair Value Carrying Value Total Level 1 Level 2 Level 3 (Dollars in millions) Assets Cash and cash equivalents $ 208 $ 208 $ 208 $ — $ — Investment securities available-for-sale 1,294 1,294 — 1,294 — Investment securities held-to-maturity 1,268 1,262 — 1,262 — Loans held-for-sale 2,576 2,578 — 2,578 — Loans with government guarantees 485 469 — 469 — Loans held-for-investment, net 6,165 6,121 — 6 6,115 Repossessed assets 17 17 — — 17 Federal Home Loan Bank stock 170 170 — 170 — Mortgage servicing rights 296 296 — — 296 Bank owned life insurance 178 178 — 178 — Other assets, foreclosure claims 210 210 — 210 — Derivative financial instruments, assets 58 58 — 32 26 Liabilities Retail deposits Demand deposits and savings accounts (5,008 ) (4,744 ) — (4,744 ) — Certificates of deposit (826 ) (833 ) — (833 ) — Government deposits (1,062 ) (1,045 ) — (1,045 ) — Company controlled deposits (1,039 ) (947 ) — (947 ) — Federal Home Loan Bank advances (3,541 ) (3,543 ) — (3,543 ) — Long-term debt (247 ) (89 ) — (89 ) — Warrant liabilities (8 ) (8 ) — (8 ) — DOJ litigation settlement (84 ) (84 ) — — (84 ) Derivative financial instruments, liabilities (18 ) (18 ) (1 ) (17 ) — The methods and assumptions used by us in estimating fair value of financial instruments which are required for disclosure only, are as follows: Cash and cash equivalents. Due to their short-term nature, the carrying amount of cash and cash equivalents approximates fair value. Investment securities held-to-maturity. Fair values are generated using market inputs, where possible, including quoted prices (the closing price in an exchange market), bid prices (the price at which a buyer stands ready to purchase), and other market information. Loans with government guarantees. The fair value is estimated by using internally developed discounted cash flow models using market interest rate inputs as well as management’s best estimate of spreads for similar collateral. Loans held-for-investment. The fair value is estimated using internally developed discounted cash flow models using market interest rate inputs as well as management’s best estimate of spreads for similar collateral. Federal Home Loan Bank stock. No secondary market exists for Federal Home Loan Bank stock. The stock is bought and sold at par by the Federal Home Loan Bank. Management believes that the recorded value equals the fair value. Bank owned life insurance. The fair value of bank owned life insurance policies is based on the cash surrender values of the policies as reported by the insurance companies. Other assets, foreclosure claims. The fair value of foreclosure claims with government guarantees approximates the carrying amount. Deposit accounts. The fair value of deposits with no defined maturity is estimated based on a discounted cash flow model that incorporates current market rates for similar products and expected attrition. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for certificates of deposit with similar remaining maturities. Federal Home Loan Bank advances. Rates currently available for debt with similar terms and remaining maturities are used to estimate the fair value of the existing debt. Long-term debt. The fair value of the long-term debt is estimated based on a discounted cash flow model that incorporates current borrowing rates for similar types of borrowing arrangements. Fair Value Option We elected the fair value option for certain items as discussed throughout the Notes to the Consolidated Financial Statements to mitigate a divergence between accounting losses and economic exposure. Interest income on loans held-for-sale is accrued on the principal outstanding primarily using the "simple-interest" method. The following table reflects the change in fair value included in earnings of financial instruments for which the fair value option has been elected: Three Months Ended March 31, 2016 2015 Assets (Dollars in millions) Loans held-for-sale Net gain on loan sales $ 144 $ 105 Loans held-for-investment Other noninterest income — (20 ) Liabilities Long-term debt Other noninterest income $ — $ (15 ) The following table reflects the difference between the aggregate fair value and aggregate remaining contractual principal balance outstanding as of March 31, 2016 and December 31, 2015 for assets and liabilities for which the fair value option has been elected: March 31, 2016 December 31, 2015 (Dollars in millions) Unpaid Principal Balance Fair Value Fair Value Over / (Under) Unpaid Principal Balance Unpaid Principal Balance Fair Value Fair Value Over / (Under) Unpaid Principal Balance Assets Nonaccrual loans Loans held-for-sale $ 1 $ 1 $ — $ 1 $ — $ (1 ) Loans held-for-investment 21 11 (10 ) 21 10 (11 ) Total nonaccrual loans $ 22 $ 12 $ (10 ) $ 22 $ 10 $ (12 ) Other performing loans Loans held-for-sale $ 2,457 $ 2,570 $ 113 $ 2,451 $ 2,541 $ 90 Loans held-for-investment 102 91 (11 ) 112 101 (11 ) Total other performing loans $ 2,559 $ 2,661 $ 102 $ 2,563 $ 2,642 $ 79 Total loans Loans held-for-sale $ 2,458 $ 2,571 $ 113 $ 2,452 $ 2,541 $ 89 Loans held-for-investment 123 102 (21 ) 133 111 (22 ) Total loans $ 2,581 $ 2,673 $ 92 $ 2,585 $ 2,652 $ 67 Liabilities Litigation settlement (1) $ (118 ) (84 ) $ 34 $ (118 ) (84 ) $ 34 (1) We are obligated to pay $118 million in installment payments upon meeting certain performance conditions.

Segment Reporting [Abstract]
Segment Information	Segment Information Our operations are conducted through four operating segments: 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. Effective January 1, 2016, we reorganized our reportable segments to align with our new management reporting structure and to align with our long-term strategy. All prior periods were reclassified to be consistent with the current presentation. Prior to the reorganization, representation and warranty reserves were reported in the Mortgage Servicing segment and the MSR asset and associated costs were reported in the Other segment. As a result of this change, representation and warranty reserves, as well as the MSR asset and associated costs are now reported in the Mortgage Originations segment. The Mortgage Originations segment originates, acquires and sells one-to-four family residential mortgage loans. The origination and acquisition of mortgage loans comprises the majority of the lending activity. Mortgage loans are originated through home loan centers, national call centers, the Internet and unaffiliated banks and mortgage banking and brokerage companies, where the net interest income and the gains from sales associated with these loans are recognized in the Mortgage Originations segment. The Mortgage Servicing segment services and sub-services mortgage loans, on a fee basis, for others. Also, the Mortgage Servicing segment services, on a fee basis, residential mortgages held-for-investment by the Community Banking segment and mortgage servicing rights held by the Mortgage Originations segment. The Mortgage Servicing segment may also collect ancillary fees, such as late fees, and earns income through the use of noninterest-bearing escrows. The 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, consumer loans, commercial loans, and warehouse lines of credit. Other financial services available to consumer and commercial customers include lines of credit, revolving credit, customized treasury management solutions, equipment leasing, inventory, and accounts receivable lending and capital markets services such as interest rate risk protection products. The Other segment includes the treasury functions, funding revenue associated with stockholders' equity, the impact of interest rate risk management, the impact of balance sheet funding activities, and miscellaneous other expenses of a corporate nature. Treasury functions include administering the investment securities portfolios, balance sheet funding, and interest rate risk management. In addition, the Other segment includes revenue and expenses related to treasury and corporate assets and liabilities and equity not directly assigned or allocated to the Mortgage Originations, Mortgage Servicing or Community Banking operating segments. Revenues are comprised of net interest income (before the provision (benefit) for loan losses) and noninterest income. Noninterest expenses are fully allocated to each operating segment. Allocation methodologies may be subject to periodic adjustment as the internal management accounting system is revised and the business or product lines within the segments change.

Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." Under the amended guidance, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The FASB has voted to approve a year deferral of the effective date from January 1, 2017 to January 1, 2018, while allowing for early adoption. In April 2016, the FASB clarified the following two aspects: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. Management is currently evaluating this guidance and does not expect this guidance to have a material impact on our Consolidated Financial Statements, but significant changes to disclosures in the Notes thereto will be required. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The new standard significantly revises an entity’s accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. It also amends certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 is effective retrospectively for fiscal years beginning after December 15, 2017 and early adoption is permitted. Management is currently evaluating this guidance and does not expect this guidance to have a material impact on our Consolidated Financial Statements, if any. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842): Section A - Leases: Amendments to the FASB Accounting Standards Codification, Section B - Conforming Amendments Related to Leases: Amendment to the FASB Accounting Standards Codification, Section C - Background Information and Basis For Conclusions. Lessees will need to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting. ASU 2016-02 is effective retrospectively for fiscal years beginning after December 15, 2019 and early adoption is permitted. The guidance in ASU 2016-02 supersedes Topic 840, Leases. Management is currently evaluating this guidance and does not expect this guidance to have a material impact on our Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815) - Contingent Put and Call Options in Debt Instruments. The amendments in ASU 2016-06 clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in ASU 2016-06 is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. ASU 2016-06 is effective retrospectively for fiscal years beginning after December 15, 2016 and early adoption is permitted. This guidance is not expected to have a material impact upon adoption on our Consolidated Financial Statements, but disclosures to the Notes thereto will be updated per the requirements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The amendments in ASU 2016-09 affect all entities that issue share-based payment awards to their employees. The areas for simplification in ASU 2016-09 involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective retrospectively for fiscal years beginning after December 15, 2016 and early adoption is permitted. Management is currently evaluating this guidance and does not expect this guidance to have a material impact on our Consolidated Financial Statements.

Accounting Policies [Abstract]
Credit Quality	Credit Quality We utilize an internal risk rating system in accordance with the Rating Credit Risk booklet of the Comptroller's Handbook, April 2011 and the Uniform Retail Credit classification and Account Management Policy issued June 20, 2000 by the Federal Financial Institution Examination Council (FFIEC) which is applied to all consumer and commercial loans. Descriptions of our internal risk ratings as they relate to credit quality follow the ratings used by the U.S. bank regulatory agencies as listed below. Pass. Pass assets are not impaired nor do they have any known deficiencies that could impact the quality of the asset. Watch. Watch assets are defined as pass rated assets that exhibit elevated risk characteristics or other factors that deserve management’s close attention and increased monitoring. However, the asset does not exhibit a potential or well-defined weakness that would warrant a downgrade to criticized or adverse classification. Special mention. Assets identified as special mention possess credit deficiencies or potential weaknesses deserving management's close attention. Special mention assets have a potential weakness or pose an unwarranted financial risk that, if not corrected, could weaken the assets and increase risk in the future. Special mention assets are criticized, but do not expose an institution to sufficient risk to warrant adverse classification. Substandard . Assets identified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. For HELOC loans and other consumer loans, we evaluate credit quality based on the aging and status of payment activity and any other known credit characteristics that call into question full repayment of the asset. Nonperforming loans are classified as either substandard, doubtful or loss. Doubtful . An asset classified as doubtful has all the weaknesses inherent in one classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. A doubtful asset has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral, and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Because of high probability of loss, non-accrual accounting treatment is required for doubtful assets. Loss. An asset classified as loss is considered uncollectible and of such little value that the continuance as bankable asset is not warranted. This classification does not mean that an asset has absolutely no recovery or salvage value, but, rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future.
Derivative Financial Instruments	Derivative Financial Instruments Derivative financial instruments are recorded at fair value in other assets and other liabilities on the Consolidated Statements of Financial Condition after taking into account the effects of legally enforceable bilateral collateral and master netting agreements. The Company is exposed to non-performance risk by the counterparties to its various derivative financial instruments. The Company believes that the non-performance risk inherent in all its derivative contracts is minimal based on credit standards and the collateral provisions of the derivative agreements. A majority of the Company’s derivatives are centrally cleared through a Central Counterparty Clearing House or consist of residential mortgage interest rate lock commitments further limiting non-performance risk. Derivatives not designated as hedging instruments: The Company maintains a derivative portfolio of interest rate swaps, futures and forward commitments used to manage exposure to changes in interest rates, MSR asset values and to meet the needs of customers. The Company also enters into interest rate lock commitments, which are commitments to originate mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. Market risk on interest rate lock commitments and mortgage loans held-for-sale is managed using corresponding forward sale commitments. Changes in fair value of derivatives not designated as hedging instruments are recognized in the Consolidated Statements of Income. Derivatives designated as hedging instruments: We use interest rate swaps to hedge the forecasted cash flows from our underlying variable-rate Federal Home Loan Bank (FHLB) advances in a qualifying cash flow hedge accounting relationship. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense in the same period in which the hedge transaction is recognized in earnings. At March 31, 2016 , we had $31 million (net-of-tax) recorded of unrealized losses on derivatives classified as cash flow hedges recorded in other comprehensive income (loss) related to derivatives classified as cash flow hedges, compared to $3 million at December 31, 2015 . The estimated amount to be reclassified from other comprehensive income into earnings during the next 12 months represents $9 million of losses (net-of-tax). Derivatives that are designated in hedging relationships are assessed for effectiveness using regression analysis at inception and throughout the hedge period. All cash flow hedges were highly effective as of March 31, 2016 . Cash flows and the profit impact associated with designated hedges are reported in the same category as the underlying hedged item.
Fair Value Measurements	Fair Value Measurements We utilize fair value measurements to record or disclose the fair value on certain assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability through an orderly transaction between market participants at the measurement date. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation models rely on market-based parameters when available, such as interest rate yield curves or credit spreads. Unobservable inputs may be based on management's judgment, assumptions and estimates related to credit quality, our future earnings, interest rates and other relevant inputs. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. Valuation Hierarchy U.S. GAAP establishes a three-level valuation hierarchy for disclosure of fair value measurements. The hierarchy is based on the transparency of the inputs used in the valuation process with the highest priority given to quoted prices available in active markets and the lowest priority to unobservable inputs where no active market exists, as discussed below. Level 1 - Quoted prices (unadjusted) for identical assets or liabilities in active markets in which we can participate as of the measurement date; Level 2 - Quoted prices for similar instruments in active markets, and other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument; and Level 3 - Unobservable inputs that reflect our own assumptions about the assumptions that market participants would use in pricing 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. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy. Assets Investment securities available-for-sale. These securities are comprised of U.S. government sponsored agencies and municipal obligations. We measure fair value using prices obtained from pricing services. A review is performed on the security prices received from the pricing services, which includes discussion and analysis of the inputs used by the pricing services to value our securities and comparisons to independent pricing. Where possible, fair values are generated using market inputs including quoted prices (the closing price in an exchange market), bid prices (the price at which a buyer stands ready to purchase), and other market information. For fixed income securities that are not actively traded, the pricing services use alternative methods to determine fair value for the securities, including quotes for similar fixed-income securities, matrix pricing, discounted cash flow using benchmark curves or other factors to determine fair value. Investment securities are classified within level 2 of the valuation hierarchy. Loans held-for-sale. We generally estimate the fair value of loans held-for-sale based on quoted market prices for securities backed by similar types of loans. Where quoted market prices were available, such market prices were utilized as estimates for fair values. Otherwise, the fair value of loans was computed by discounting cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. These loans are classified as level 2. Loans held-for-investment. Loans held-for-investment are generally recorded at amortized cost. Such loans are not recorded at fair value on a recurring basis. However, from time to time, a loan becomes impaired when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Once a loan is identified as impaired, the fair value of the impaired loan is estimated using one of several methods, including collateral value less costs to sell, market value of similar debt, or discounted cash flows. The fair value of the underlying collateral is determined, where possible, using market prices derived from appraisals or market evaluations which are considered a nonrecurring level 3 valuation. Fair value may also be measured using the present value of expected cash flows discounted at the loan's effective interest rate. Loans held-for-investment that are recorded at fair value on a recurring basis are loans that were previously recorded as loans held-for-sale but subsequently transferred to the held-for-investment category. As we elected the fair value option for the held-for-sale loans, they continue to be reported at fair value and measured consistent with the level 2 methodology for loans held-for-sale. Certain HELOC loans have been recorded in the Consolidated Financial Statement as loans held-for-investment at fair value. We record these loans as a recurring level 3 valuation. Also included in loans held-for-investment are the second mortgage loans which are carried at fair value and valued using a discounted estimated net future cash flow model and are classified within the level 3 valuation hierarchy as the model utilizes significant inputs which are unobservable. Repossessed assets. Repossessed assets are measured and reported at fair value through a charge-off to the allowance for loan losses based upon the fair value of the repossessed asset. The fair value of repossessed assets, upon initial recognition, are estimated using level 3 inputs based on appraisals or evaluations. The significant unobservable inputs used in the level 3 fair value measurements of our impaired loans and repossessed assets primarily relate to internal valuations or analysis. Mortgage Servicing Rights. The current market for MSRs is not sufficiently liquid to provide participants with quoted market prices. Therefore, we use an option-adjusted spread valuation approach to determine the fair value of MSRs. This approach consists of projecting servicing cash flows under multiple interest rate scenarios and discounting these cash flows using risk-adjusted discount rates. 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 our internal valuation model. In certain circumstances, based on the probability of the completion of a sale of MSRs pursuant to a bona-fide purchase offer, we consider 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. Due to the nature of the valuation inputs, MSRs are classified within level 3 of the valuation hierarchy. Derivative financial instruments. Certain classes of derivative contracts are listed on an exchange and are actively traded, and they are therefore classified within level 1 of the valuation hierarchy. These include U.S. Treasury futures and U.S. Treasury options. Our forward loan sale commitments, swap futures and interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable and are classified within level 2 of the valuation hierarchy. Rate lock commitments are valued using internal models with significant unobservable market parameters and therefore are classified within level 3 of the valuation hierarchy. We assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and determined that the credit valuation adjustments were not significant to the overall valuation of our derivatives. We use interest rate swaps to hedge the forecasted cash flows from our underlying variable-rate FHLB advances in a qualifying cash flow hedge accounting relationship. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense along with the debt interest expense in the same period in which the identified hedge transaction is recognized in earnings. The derivatives are reported in either other assets or other liabilities on the Consolidated Statements of Financial Condition. Liabilities Warrants. 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. Litigation settlement. Upon settlement of the DOJ litigation settlement, we elected the fair value option to account for the liability representing the remaining future payments. As of March 31, 2016 the fair value totaled $84 million , using a discount rate of 7.3 percent for which we use a discounted cash flow model to determine the current fair value. The model utilizes our forecast and considers multiple scenarios including possible outcomes that impact the timing of the additional payments which are discounted using a risk free rate adjusted for nonperformance risk that represents our credit risk. These scenarios are probability weighted and consider the view of an independent market participant to estimate the most likely fair value of the liability. The liability is classified within level 3 of the valuation hierarchy as the projections of earnings and growth rate and other assumptions are unobservable inputs which affect the estimated timing of the cash flow payments. We consider factors which could affect those projections from the perspective of a market participant, which is incorporated into the assessment of fair value.

Fair Value Inputs, Assets and Liabilities Measured on Recurring Basis, Quantitative Information	The following tables present the quantitative information about recurring level 3 fair value financial instruments and the fair value measurements as of March 31, 2016 and December 31, 2015 : Fair Value Valuation Technique Unobservable Input Range (Weighted Average) March 31, 2016 (Dollars in millions) Assets Second mortgage loans $ 40 Discounted cash flows Discount rate 7.2% - 10.8% (9.0%) HELOC loans $ 55 Discounted cash flows Discount rate 7.4% - 11.1% (9.2%) Mortgage servicing rights $ 281 Discounted cash flows Option adjusted spread 6.5% - 9.8% (8.2%) Liabilities DOJ litigation settlement $ (84 ) Discounted cash flows Discount rate 5.9% - 8.8% (7.3%) Derivative financial instruments Rate lock commitments $ 61 Consensus pricing Origination pull-through rate 65.0% - 97.4% (81.2%) Fair Value Valuation Technique Unobservable Input Range (Weighted Average) December 31, 2015 (Dollars in millions) Assets Second mortgage loans $ 42 Discounted cash flows Discount rate 7.2% - 10.8% (9.0%) HELOC loans $ 64 Discounted cash flows Discount rate 6.8% - 10.1% (8.4%) Mortgage servicing rights $ 296 Discounted cash flows Option adjusted spread 6.6% - 9.9% (8.2%) Liabilities DOJ litigation settlement $ (84 ) Discounted cash flows Discount rate 4.9% - 9.5% (7.2%) Derivative financial instruments Rate lock commitments $ 26 Consensus pricing Origination pull-through rate 67.6% - 101.5% (84.6%)
Fair Value Inputs, Assets, Quantitative Information	The significant unobservable inputs used in the fair value measurement of the MSRs are option adjusted spreads, prepayment rates, and cost to service. Significant increases (decreases) in all three assumptions in isolation would result in a significantly lower (higher) fair value measurement. Additionally, the key economic assumptions used in determining the fair value of MSRs capitalized during the three months ended March 31, 2016 and 2015 periods were as follows: Three Months Ended March 31, 2016 2015 Weighted average life (in years) 7.3 7.3 Weighted average constant prepayment rate 13.8 % 13.6 % Weighted average option adjusted spread 7.29 % 8.53 % The key economic assumptions reflected in the overall fair value of the entire portfolio of MSRs were as follows: March 31, December 31, Weighted average life (in years) 6.4 7.3 Weighted average constant prepayment rate 15.2 % 12.6 % Weighted average option adjusted spread 8.18 % 8.24 %
Fair Value Measurements, Nonrecurring	These assets are measured at the lower of cost or market and had a fair value below cost at the end of the period as summarized below: Total (1) Level 2 Level 3 (Dollars in millions) March 31, 2016 Loans held-for-sale (2) $ 7 $ 7 $ — Impaired loans held-for-investment (3) Residential first mortgage loans 16 — 16 Commercial and industrial loans 1 — 1 Repossessed assets (4) 14 — 14 Totals $ 38 $ 7 $ 31 December 31, 2015 Loans held-for-sale (2) $ 8 $ 8 $ — Impaired loans held-for-investment (3) Residential first mortgage loans 40 — 40 Commercial real estate loans 2 — 2 Repossessed assets (4) 17 — 17 Totals $ 67 $ 8 $ 59 (1) The fair values are obtained at various dates during the three months ended March 31, 2016 and the year ended December 31, 2015 , respectively. (2) We recorded less than $1 million and $1 million in fair value losses on loans held-for-sale for which we did not elect the fair value option (included in interest income on the Consolidated Statements of Operations) during the three months ended March 31, 2016 and March 31, 2015 , respectively. (3) We recorded $11 million and $4 million in fair value losses on impaired loans (included in provision (benefit) for loan losses on Consolidated Statements of Operations) during the three months ended March 31, 2016 and March 31, 2015 , respectively. (4) We recorded less than $1 million in losses related to write downs of repossessed assets based on the estimated fair value of the specific assets during the three months ended March 31, 2016 and recognized net gain of $1 million on sales of repossessed assets (both write downs and net gains/losses are included in assets resolution expense on the Consolidated Statements of Operations) during the three months ended March 31, 2016 . We recorded $1 million in losses related to write downs of repossessed assets based on the estimated fair value of the specific assets during the three months ended March 31, 2015 and recognized a net loss of zero on sales of repossessed assets during the three months ended March 31, 2015 .
