Accounting Policies [Abstract]
Summary of Significant Accounting Principles	NOTE 1 – Summary of Significant Accounting Principles Bank of America Corporation (together with its consolidated subsidiaries, the Corporation), a bank holding company and a financial holding company, provides a diverse range of financial services and products throughout the U.S. and in certain international markets. The term "the Corporation" as used herein may refer to Bank of America Corporation individually, Bank of America Corporation and its subsidiaries, or certain of Bank of America Corporation's subsidiaries or affiliates. Principles of Consolidation and Basis of Presentation The Consolidated Financial Statements include the accounts of the Corporation and its majority-owned subsidiaries, and those variable interest entities (VIEs) where the Corporation is the primary beneficiary. Intercompany accounts and transactions have been eliminated. Results of operations of acquired companies are included from the dates of acquisition and for VIEs, from the dates that the Corporation became the primary beneficiary. Assets held in an agency or fiduciary capacity are not included in the Consolidated Financial Statements. The Corporation accounts for investments in companies for which it owns a voting interest and for which it has the ability to exercise significant influence over operating and financing decisions using the equity method of accounting. These investments are included in other assets. Equity method investments are subject to impairment testing and the Corporation's proportionate share of income or loss is included in equity investment income. The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts and disclosures. Realized results could differ from those estimates and assumptions. The Corporation's Annual Report on Form 10-K for the year ended December 31, 2014 as supplemented by a Current Report on Form 8-K filed on April 29, 2015 to reflect reclassified business segment information is referred to herein as the 2014 Annual Report on Form 10-K. These unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K. The nature of the Corporation's business is such that the results of any interim period are not necessarily indicative of results for a full year. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim period results have been made. The Corporation evaluates subsequent events through the date of filing with the Securities and Exchange Commission (SEC). Certain prior-period amounts have been reclassified to conform to current period presentation. In the Consolidated Statement of Cash Flows for the six months ended June 30, 2014 , the Corporation revised certain line item amounts (e.g., purchases and proceeds from sales of debt securities carried at fair value) in the investing activities section to appropriately reflect sweep activity. This had no impact on total cash flows from investing activities. New Accounting Pronouncements In February 2015, the Financial Accounting Standards Board (FASB) issued new accounting guidance that amends the criteria for determining whether limited partnerships and similar entities are VIEs, clarifies when a general partner or asset manager should consolidate an entity and eliminates the indefinite deferral of certain aspects of VIE accounting guidance for investments in certain investment funds. Money market funds registered under Rule 2a-7 of the Investment Company Act and similar funds are exempt from consolidation under the new guidance. The new accounting guidance is effective beginning on January 1, 2016. Early adoption is permitted; however, the Corporation does not expect to adopt this new guidance early. The Corporation does not expect the new guidance to have a material impact on its consolidated financial position or results of operations. In June 2014, the FASB issued new guidance on accounting and disclosure of repurchase-to-maturity (RTM) transactions and repurchase financings (repos). Under this new accounting guidance, RTMs are accounted for as secured borrowings rather than sales of an asset, and transfers of financial assets with a contemporaneous repo are no longer evaluated to determine whether they should be accounted for on a combined basis as forward contracts. The new guidance also prescribes additional disclosures particularly on the nature of collateral pledged in repos accounted for as secured borrowings. The new guidance was effective beginning on January 1, 2015 and did not have a material impact on the Corporation's consolidated financial position or results of operations. For the additional disclosures under this guidance, see Note 2 – Derivatives and Note 9 – Federal Funds Sold or Purchased, Securities Financing Agreements and Short-term Borrowings . In May 2014, the FASB issued new accounting guidance to clarify the principles for recognizing revenue from contracts with customers. The new accounting guidance, which does not apply to financial instruments, is effective on a retrospective basis beginning on January 1, 2018. The Corporation is assessing the impact of this new guidance on its consolidated financial position and results of operations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	NOTE 2 – Derivatives Derivative Balances Derivatives are entered into on behalf of customers, for trading, or to support risk management activities. Derivatives used in risk management activities include derivatives that may or may not be designated in qualifying hedge accounting relationships. Derivatives that are not designated in qualifying hedge accounting relationships are referred to as other risk management derivatives. For more information on the Corporation's derivatives and hedging activities, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . The following tables present derivative instruments included on the Consolidated Balance Sheet in derivative assets and liabilities at June 30, 2015 and December 31, 2014 .

Offsetting of Derivatives The Corporation enters into International Swaps and Derivatives Association, Inc. (ISDA) master netting agreements or similar agreements with substantially all of the Corporation's derivative counterparties. Where legally enforceable, these master netting agreements give the Corporation, in the event of default by the counterparty, the right to liquidate securities held as collateral and to offset receivables and payables with the same counterparty. For purposes of the Consolidated Balance Sheet, the Corporation offsets derivative assets and liabilities and cash collateral held with the same counterparty where it has such a legally enforceable master netting agreement. The Offsetting of Derivatives table presents derivative instruments included in derivative assets and liabilities on the Consolidated Balance Sheet at June 30, 2015 and December 31, 2014 by primary risk (e.g., interest rate risk) and the platform, where applicable, on which these derivatives are transacted. Exchange-traded derivatives include listed options transacted on an exchange. Over-the-counter (OTC) derivatives include bilateral transactions between the Corporation and a particular counterparty. OTC-cleared derivatives include bilateral transactions between the Corporation and a counterparty where the transaction is cleared through a clearinghouse. Balances are presented on a gross basis, prior to the application of counterparty and cash collateral netting. Total gross derivative assets and liabilities are adjusted on an aggregate basis to take into consideration the effects of legally enforceable master netting agreements which includes reducing the balance for counterparty netting and cash collateral received or paid. Other gross derivative assets and liabilities in the table represent derivatives entered into under master netting agreements where uncertainty exists as to the enforceability of these agreements under bankruptcy laws in some countries or industries and, accordingly, receivables and payables with counterparties in these countries or industries are reported on a gross basis. Also included in the table is financial instruments collateral related to legally enforceable master netting agreements that represents securities collateral received or pledged and customer cash collateral held at third-party custodians. These amounts are not offset on the Consolidated Balance Sheet but are shown as a reduction to total derivative assets and liabilities in the table to derive net derivative assets and liabilities.

ALM and Risk Management Derivatives The Corporation's asset and liability management (ALM) and risk management activities include the use of derivatives to mitigate risk to the Corporation including derivatives designated in qualifying hedge accounting relationships and derivatives used in other risk management activities. Interest rate, foreign exchange, equity, commodity and credit contracts are utilized in the Corporation's ALM and risk management activities. The Corporation maintains an overall interest rate risk management strategy that incorporates the use of interest rate contracts, which are generally non-leveraged generic interest rate and basis swaps, options, futures and forwards, to minimize significant fluctuations in earnings caused by interest rate volatility. The Corporation's goal is to manage interest rate sensitivity and volatility so that movements in interest rates do not significantly adversely affect earnings or capital. As a result of interest rate fluctuations, hedged fixed-rate assets and liabilities appreciate or depreciate in fair value. Gains or losses on the derivative instruments that are linked to the hedged fixed-rate assets and liabilities are expected to substantially offset this unrealized appreciation or depreciation. Market risk, including interest rate risk, can be substantial in the mortgage business. Market risk is the risk that values of mortgage assets or revenues will be adversely affected by changes in market conditions such as interest rate movements. To mitigate the interest rate risk in mortgage banking production income, the Corporation utilizes forward loan sale commitments and other derivative instruments, including purchased options, and certain debt securities. The Corporation also utilizes derivatives such as interest rate options, interest rate swaps, forward settlement contracts and eurodollar futures to hedge certain market risks of mortgage servicing rights (MSR). For more information on MSRs, see Note 17 – Mortgage Servicing Rights . The Corporation uses foreign exchange contracts to manage the foreign exchange risk associated with certain foreign currency-denominated assets and liabilities, as well as the Corporation's investments in non-U.S. subsidiaries. Foreign exchange contracts, which include spot and forward contracts, represent agreements to exchange the currency of one country for the currency of another country at an agreed-upon price on an agreed-upon settlement date. Exposure to loss on these contracts will increase or decrease over their respective lives as currency exchange and interest rates fluctuate. The Corporation enters into derivative commodity contracts such as futures, swaps, options and forwards as well as non-derivative commodity contracts to provide price risk management services to customers or to manage price risk associated with its physical and financial commodity positions. The non-derivative commodity contracts and physical inventories of commodities expose the Corporation to earnings volatility. Fair value accounting hedges provide a method to mitigate a portion of this earnings volatility. The Corporation purchases credit derivatives to manage credit risk related to certain funded and unfunded credit exposures. Credit derivatives include credit default swaps (CDS), total return swaps and swaptions. These derivatives are recorded on the Consolidated Balance Sheet at fair value with changes in fair value recorded in other income. Derivatives Designated as Accounting Hedges The Corporation uses various types of interest rate, commodity and foreign exchange derivative contracts to protect against changes in the fair value of its assets and liabilities due to fluctuations in interest rates, commodity prices and exchange rates (fair value hedges). The Corporation also uses these types of contracts and equity derivatives to protect against changes in the cash flows of its assets and liabilities, and other forecasted transactions (cash flow hedges). The Corporation hedges its net investment in consolidated non-U.S. operations determined to have functional currencies other than the U.S. Dollar using forward exchange contracts and cross-currency basis swaps, and by issuing foreign currency-denominated debt (net investment hedges). Fair Value Hedges The table below summarizes information related to fair value hedges for the three and six months ended June 30, 2015 and 2014 , including hedges of interest rate risk on long-term debt that were acquired as part of a business combination and redesignated at that time. At redesignation, the fair value of the derivatives was positive. As the derivatives mature, the fair value will approach zero. As a result, ineffectiveness will occur and the fair value changes in the derivatives and the long-term debt being hedged may be directionally the same in certain scenarios. Based on a regression analysis, the derivatives continue to be highly effective at offsetting changes in the fair value of the long-term debt attributable to interest rate risk.

Cash Flow and Net Investment Hedges The table below summarizes certain information related to cash flow hedges and net investment hedges for the three and six months ended June 30, 2015 and 2014 . Of the $1.4 billion net loss (after-tax) on derivatives in accumulated other comprehensive income (OCI) at June 30, 2015 , $698 million ( $436 million after-tax) is expected to be reclassified into earnings in the next 12 months. These net losses reclassified into earnings are expected to primarily reduce net interest income related to the respective hedged items. Amounts related to price risk on restricted stock awards reclassified from accumulated OCI are recorded in personnel expense.

(2) The hedge gain (loss) recognized in accumulated OCI is primarily related to the change in the Corporation's stock price for the period. Other Risk Management Derivatives Other risk management derivatives are used by the Corporation to reduce certain risk exposures. These derivatives are not qualifying accounting hedges because either they did not qualify for or were not designated as accounting hedges. The table below presents gains (losses) on these derivatives for the three and six months ended June 30, 2015 and 2014 . These gains (losses) are largely offset by the income or expense that is recorded on the hedged item. Other Risk Management Derivatives Gains (Losses) Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions) 2015 2014 2015 2014 Interest rate risk on mortgage banking income (1) $ (390 ) $ 196 $ (94 ) $ 376 Credit risk on loans (2) (31 ) (27 ) (58 ) (33 ) Interest rate and foreign currency risk on ALM activities (3) 585 (713 ) 266 (1,311 ) Price risk on restricted stock awards (4) 226 (338 ) (244 ) 26 Other (20 ) (1 ) (7 ) (4 ) (1) Net gains (losses) on these derivatives are recorded in mortgage banking income as they are used to mitigate the interest rate risk related to MSRs, interest rate lock commitments and mortgage loans held-for-sale, all of which are measured at fair value with changes in fair value recorded in mortgage banking income. The net gains on interest rate lock commitments related to the origination of mortgage loans that are held-for-sale, which are not included in the table but are considered derivative instruments, were $167 million and $427 million for the three and six months ended June 30, 2015 compared to $225 million and $398 million for the same periods in 2014 . (2) Primarily related to derivatives that are economic hedges of credit risk on loans. Net gains (losses) on these derivatives are recorded in other income. (3) Primarily related to hedges of debt securities carried at fair value and hedges of foreign currency-denominated debt. Gains (losses) on these derivatives and the related hedged items are recorded in other income. (4) Gains (losses) on these derivatives are recorded in personnel expense. Transfers of Financial Assets with Risk Retained through Derivatives The Corporation enters into certain transactions involving the transfer of financial assets that are accounted for as sales where substantially all of the economic exposure to the transferred financial assets is retained by the Corporation through a derivative agreement with the initial transferee. These transactions are accounted for as sales because the Corporation does not retain control over the assets transferred. Through June 30, 2015 , the Corporation transferred $8.9 billion of non-U.S. government-guaranteed mortgage-backed securities (MBS) and non-U.S. government securities primarily to a trust created by a third party. The Corporation received gross cash proceeds of $8.9 billion at the transfer dates. The Corporation simultaneously entered into derivatives with those counterparties whereby the Corporation retained certain economic exposures to those securities (e.g., interest rate and/or credit risk). Generally, the maturity of the derivatives is the same as the maturity of assets initially transferred. A derivative asset of $110 million and a liability of $15 million were recorded at June 30, 2015 and are included in credit derivatives in the derivative instruments table on page 142 . At June 30, 2015 , the fair value of the securities previously transferred was $9.1 billion . The economic exposure retained by the Corporation, which is primarily interest rate risk and prepayment risk, is typically hedged with interest rate swaps and interest rate swaptions and, to a lesser extent, total return swaps. Sales and Trading Revenue The Corporation enters into trading derivatives to facilitate client transactions and to manage risk exposures arising from trading account assets and liabilities. It is the Corporation's policy to include these derivative instruments in its trading activities which include derivatives and non-derivative cash instruments. The resulting risk from these derivatives is managed on a portfolio basis as part of the Corporation's Global Markets business segment. The related sales and trading revenue generated within Global Markets is recorded in various income statement line items including trading account profits and net interest income as well as other revenue categories. Sales and trading revenue includes changes in the fair value and realized gains and losses on the sales of trading and other assets, net interest income, and fees primarily from commissions on equity securities. Revenue is generated by the difference in the client price for an instrument and the price at which the trading desk can execute the trade in the dealer market. For equity securities, commissions related to purchases and sales are recorded in the "Other" column in the Sales and Trading Revenue table. Changes in the fair value of these securities are included in trading account profits. For debt securities, revenue, with the exception of interest associated with the debt securities, is typically included in trading account profits. Unlike commissions for equity securities, the initial revenue related to broker-dealer services for debt securities is typically included in the pricing of the instrument rather than being charged through separate fee arrangements. Therefore, this revenue is recorded in trading account profits as part of the initial mark to fair value. For derivatives, the majority of revenue is included in trading account profits. In transactions where the Corporation acts as agent, which include exchange-traded futures and options, fees are recorded in other income. The table below, which includes both derivatives and non-derivative cash instruments, identifies the amounts in the respective income statement line items attributable to the Corporation's sales and trading revenue in Global Markets , categorized by primary risk, for the three and six months ended June 30, 2015 and 2014 . The difference between total trading account profits in the table below and in the Consolidated Statement of Income represents trading activities in business segments other than Global Markets . This table includes debit valuation and funding valuation adjustment (DVA/FVA) gains (losses). Global Markets results in Note 18 – Business Segment Information are presented on a fully taxable-equivalent (FTE) basis. The table below is not presented on an FTE basis.

Includes investment and brokerage services revenue of $544 million and $1.1 billion for the three and six months ended June 30, 2015 and $540 million and $1.1 billion for the same periods in 2014 . Credit Derivatives The Corporation enters into credit derivatives primarily to facilitate client transactions and to manage credit risk exposures. Credit derivatives derive value based on an underlying third-party referenced obligation or a portfolio of referenced obligations and generally require the Corporation, as the seller of credit protection, to make payments to a buyer upon the occurrence of a pre-defined credit event. Such credit events generally include bankruptcy of the referenced credit entity and failure to pay under the obligation, as well as acceleration of indebtedness and payment repudiation or moratorium. For credit derivatives based on a portfolio of referenced credits or credit indices, the Corporation may not be required to make payment until a specified amount of loss has occurred and/or may only be required to make payment up to a specified amount. Credit derivative instruments where the Corporation is the seller of credit protection and their expiration are summarized in the table below. These instruments are classified as investment and non-investment grade based on the credit quality of the underlying referenced obligation.

However, the Corporation does not monitor its exposure to credit derivatives based solely on the notional amount because this measure does not take into consideration the probability of occurrence. As such, the notional amount is not a reliable indicator of the Corporation's exposure to these contracts. Instead, a risk framework is used to define risk tolerances and establish limits to help ensure that certain credit risk-related losses occur within acceptable, predefined limits. The Corporation manages its market risk exposure to credit derivatives by entering into a variety of offsetting derivative contracts and security positions. For example, in certain instances, the Corporation may purchase credit protection with identical underlying referenced names to offset its exposure. The carrying value and notional amount of written credit derivatives for which the Corporation held purchased credit derivatives with identical underlying referenced names and terms were $5.1 billion and $814.1 billion at June 30, 2015 , and $5.7 billion and $880.6 billion at December 31, 2014 . Credit-related notes in the table on page 150 include investments in securities issued by collateralized debt obligation (CDO), collateralized loan obligation (CLO) and credit-linked note vehicles. These instruments are primarily classified as trading securities. The carrying value of these instruments equals the Corporation's maximum exposure to loss. The Corporation is not obligated to make any payments to the entities under the terms of the securities owned. Credit-related Contingent Features and Collateral The Corporation executes the majority of its derivative contracts in the OTC market with large, international financial institutions, including broker-dealers and, to a lesser degree, with a variety of non-financial companies. Substantially all of the derivative transactions are executed on a daily margin basis. Therefore, events such as a credit rating downgrade (depending on the ultimate rating level) or a breach of credit covenants would typically require an increase in the amount of collateral required of the counterparty, where applicable, and/or allow the Corporation to take additional protective measures such as early termination of all trades. Further, as previously discussed on page 142 , the Corporation enters into legally enforceable master netting agreements which reduce risk by permitting the closeout and netting of transactions with the same counterparty upon the occurrence of certain events. A majority of the Corporation's derivative contracts contain credit risk-related contingent features, primarily in the form of ISDA master netting agreements and credit support documentation that enhance the creditworthiness of these instruments compared to other obligations of the respective counterparty with whom the Corporation has transacted. These contingent features may be for the benefit of the Corporation as well as its counterparties with respect to changes in the Corporation's creditworthiness and the mark-to-market exposure under the derivative transactions. At June 30, 2015 and December 31, 2014 , the Corporation held cash and securities collateral of $73.5 billion and $82.0 billion , and posted cash and securities collateral of $62.5 billion and $67.7 billion in the normal course of business under derivative agreements. In connection with certain OTC derivative contracts and other trading agreements, the Corporation can be required to provide additional collateral or to terminate transactions with certain counterparties in the event of a downgrade of the senior debt ratings of the Corporation or certain subsidiaries. The amount of additional collateral required depends on the contract and is usually a fixed incremental amount and/or the market value of the exposure. At June 30, 2015 , the amount of collateral, calculated based on the te

The Corporation recorded other-than-temporary impairment (OTTI) losses on AFS debt securities for the three and six months ended June 30, 2015 and 2014 as presented in the Net Credit-related Impairment Losses Recognized in Earnings table. Substantially all OTTI losses in the three and six months ended June 30, 2015 and 2014 consisted of credit losses on non-agency residential mortgage-backed securities (RMBS) and were recorded in other income in the Consolidated Statement of Income. The credit losses on the RMBS during the six months ended June 30, 2015 were driven by decreases in the estimated RMBS cash flows primarily due to a model change resulting in the refinement of the expected cash flows. A debt security is impaired when its fair value is less than its amortized cost. If the Corporation intends or will more-likely-than-not be required to sell a debt security prior to recovery, the entire impairment loss is recorded in the Consolidated Statement of Income. For AFS debt securities the Corporation does not intend or will not more-likely-than-not be required to sell, an analysis is performed to determine if any of the impairment is due to credit or whether it is due to other factors (e.g., interest rate). Credit losses are considered unrecoverable and are recorded in the Consolidated Statement of Income with the remaining unrealized losses recorded in OCI. In certain instances, the credit loss on a debt security may exceed the total impairment, in which case, the excess of the credit loss over the total impairment is recorded as an unrealized gain in OCI.

Assumptions used for the underlying loans that support the MBS can vary widely from loan to loan and are influenced by such factors as loan interest rate, geographic location of the borrower, borrower characteristics and collateral type. Based on these assumptions, the Corporation then determines how the underlying collateral cash flows will be distributed to each MBS issued from the applicable special purpose entity. Expected principal and interest cash flows on an impaired AFS debt security are discounted using the effective yield of each individual impaired AFS debt security. Significant assumptions used in estimating the expected cash flows for measuring credit losses on non-agency RMBS were as follows at June 30, 2015 . Significant Assumptions Range (1) Weighted- average 10th Percentile (2) 90th Percentile (2) Annual prepayment speed 12.0 % 3.7 % 24.2 % Loss severity 38.9 13.2 48.0 Life default rate 34.6 1.3 97.5 (1) Represents the range of inputs/assumptions based upon the underlying collateral. (2) The value of a variable below which the indicated percentile of observations will fall. Annual constant prepayment speed and loss severity rates are projected considering collateral characteristics such as loan-to-value (LTV), creditworthiness of borrowers as measured using FICO scores, and geographic concentrations. The weighted-average severity by collateral type was 35.6 percent for prime, 37.4 percent for Alt-A and 50.4 percent for subprime at June 30, 2015 . Additionally, default rates are projected by considering collateral characteristics including, but not limited to, LTV, FICO and geographic concentration. Weighted-average life default rates by collateral type were 21.5 percent for prime, 36.9 percent for Alt-A and 38.2 percent for subprime at June 30, 2015 . The expected maturity distribution of the Corporation's MBS, the contractual maturity distribution of the Corporation's other debt securities carried at fair value and HTM debt securities, and the yields on the Corporation's debt securities carried at fair value and HTM debt securities at June 30, 2015 are summarized in the table below. Actual maturities may differ from the contractual or expected maturities since borrowers may have the right to prepay obligations with or without prepayment penalties.

(9) Total outstandings includes U.S. commercial real estate loans of $45.2 billion and non-U.S. commercial real estate loans of $2.5 billion . The Corporation has entered into long-term credit protection agreements with FNMA and FHLMC on loans totaling $8.3 billion and $17.2 billion at June 30, 2015 and December 31, 2014 , providing full credit protection on residential mortgage loans that become severely delinquent. All of these loans are individually insured and therefore the Corporation does not record an allowance for credit losses related to these loans. Nonperforming Loans and Leases The Corporation classifies junior-lien home equity loans as nonperforming when the first-lien loan becomes 90 days past due even if the junior-lien loan is performing. At June 30, 2015 and December 31, 2014 , $599 million and $800 million of such junior-lien home equity loans were included in nonperforming loans. The Corporation classifies consumer real estate loans that have been discharged in Chapter 7 bankruptcy and not reaffirmed by the borrower as troubled debt restructurings (TDR), irrespective of payment history or delinquency status, even if the repayment terms for the loan have not been otherwise modified. The Corporation continues to have a lien on the underlying collateral. At June 30, 2015 , nonperforming loans discharged in Chapter 7 bankruptcy with no change in repayment terms were $980 million of which $585 million were current on their contractual payments, while $334 million were 90 days or more past due. Of the contractually current nonperforming loans, more than 75 percent were discharged in Chapter 7 bankruptcy more than 12 months ago, and more than 55 percent were discharged 24 months or more ago. As subsequent cash payments are received on these nonperforming loans that are contractually current, the interest component of the payments is generally recorded as interest income on a cash basis and the principal component is recorded as a reduction in the carrying value of the loan. During the three and six months ended June 30, 2015 , the Corporation sold nonperforming and other delinquent consumer real estate loans with a carrying value of $1.0 billion and $1.9 billion , including $401 million and $987 million of purchased credit-impaired (PCI) loans, compared to $2.1 billion and $2.8 billion , including $98 million and $552 million of PCI loans, for the same periods in 2014. The Corporation recorded recoveries related to these sales of $27 million and $67 million for the three and six months ended June 30, 2015 compared to recoveries of $185 million for both of the same periods in 2014. Gains in noninterest income of $40 million and $75 million were also recorded for the three and six months ended June 30, 2015 compared to gains of $158 million and $170 million for the same periods in 2014. The table below presents the Corporation's nonperforming loans and leases including nonperforming TDRs, and loans accruing past due 90 days or more at June 30, 2015 and December 31, 2014 . Nonperforming loans held-for-sale (LHFS) are excluded from nonperforming loans and leases as they are recorded at either fair value or the lower of cost or fair value. For more information on the criteria for classification as nonperforming, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K .

At June 30, 2015 and December 31, 2014 , residential mortgage includes $5.5 billion and $7.3 billion of loans on which interest has been curtailed by the FHA, and therefore are no longer accruing interest, although principal is still insured, and $3.4 billion and $4.1 billion of loans on which interest is still accruing. n/a = not applicable Credit Quality Indicators The Corporation monitors credit quality within its Consumer Real Estate, Credit Card and Other Consumer, and Commercial portfolio segments based on primary credit quality indicators. For more information on the portfolio segments, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . Within the Consumer Real Estate portfolio segment, the primary credit quality indicators are refreshed LTV and refreshed FICO score. Refreshed LTV measures the carrying value of the loan as a percentage of the value of the property securing the loan, refreshed quarterly. Home equity loans are evaluated using combined loan-to-value (CLTV) which measures the carrying value of the combined loans that have liens against the property and the available line of credit as a percentage of the value of the property securing the loan, refreshed quarterly. FICO score measures the creditworthiness of the borrower based on the financial obligations of the borrower and the borrower's credit history. At a minimum, FICO scores are refreshed quarterly, and in many cases, more frequently. FICO scores are also a primary credit quality indicator for the Credit Card and Other Consumer portfolio segment and the business card portfolio within U.S. small business commercial. Within the Commercial portfolio segment, loans are evaluated using the internal classifications of pass rated or reservable criticized as the primary credit quality indicators. The term reservable criticized refers to those commercial loans that are internally classified or listed by the Corporation as Special Mention, Substandard or Doubtful, which are asset quality categories defined by regulatory authorities. These assets have an elevated level of risk and may have a high probability of default or total loss. Pass rated refers to all loans not considered reservable criticized. In addition to these primary credit quality indicators, the Corporation uses other credit quality indicators for certain types of loans. The following tables present certain credit quality indicators for the Corporation's Consumer Real Estate, Credit Card and Other Consumer, and Commercial portfolio segments, by class of financing receivables, at June 30, 2015 and December 31, 2014 .

Impaired Loans and Troubled Debt Restructurings A loan is considered impaired when, based on current information, it is probable that the Corporation will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming commercial loans and all consumer and commercial TDRs. Impaired loans exclude nonperforming consumer loans and nonperforming commercial leases unless they are classified as TDRs. Loans accounted for under the fair value option are also excluded. PCI loans are excluded and reported separately on page 177 . For additional information, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . Consumer Real Estate Impaired consumer real estate loans within the Consumer Real Estate portfolio segment consist entirely of TDRs. Excluding PCI loans, most modifications of consumer real estate loans meet the definition of TDRs when a binding offer is extended to a borrower. Modifications of consumer real estate loans are done in accordance with the government's Making Home Affordable Program (modifications under government programs) or the Corporation's proprietary programs (modifications under proprietary programs). These modifications are considered to be TDRs if concessions have been granted to borrowers experiencing financial difficulties. Concessions may include reductions in interest rates, capitalization of past due amounts, principal and/or interest forbearance, payment extensions, principal and/or interest forgiveness, or combinations thereof. Prior to permanently modifying a loan, the Corporation may enter into trial modifications with certain borrowers under both government and proprietary programs. Trial modifications generally represent a three - to four -month period during which the borrower makes monthly payments under the anticipated modified payment terms. Upon successful completion of the trial period, the Corporation and the borrower enter into a permanent modification. Binding trial modifications are classified as TDRs when the trial offer is made and continue to be classified as TDRs regardless of whether the borrower enters into a permanent modification. Consumer real estate loans that have been discharged in Chapter 7 bankruptcy with no change in repayment terms and not reaffirmed by the borrower of $2.2 billion were included in TDRs at June 30, 2015 , of which $980 million were classified as nonperforming and $915 million were loans fully-insured by the Federal Housing Administration (FHA). For more information on loans discharged in Chapter 7 bankruptcy, see Nonperforming Loans and Leases in this Note. A consumer real estate loan, excluding PCI loans which are reported separately, is not classified as impaired unless it is a TDR. Once such a loan has been designated as a TDR, it is then individually assessed for impairment. Consumer real estate TDRs are measured primarily based on the net present value of the estimated cash flows discounted at the loan's original effective interest rate, as discussed in the following paragraph. If the carrying value of a TDR exceeds this amount, a specific allowance is recorded as a component of the allowance for loan and lease losses. Alternatively, consumer real estate TDRs that are considered to be dependent solely on the collateral for repayment (e.g., due to the lack of income verification) are measured based on the estimated fair value of the collateral and a charge-off is recorded if the carrying value exceeds the fair value of the collateral. Consumer real estate loans that reached 180 days past due prior to modification had been charged off to their net realizable value, less costs to sell, before they were modified as TDRs in accordance with established policy. Therefore, modifications of consumer real estate loans that are 180 or more days past due as TDRs do not have an impact on the allowance for loan and lease losses nor are additional charge-offs required at the time of modification. Subsequent declines in the fair value of the collateral after a loan has reached 180 days past due are recorded as charge-offs. Fully-insured loans are protected against principal loss, and therefore, the Corporation does not record an allowance for loan and lease losses on the outstanding principal balance, even after they have been modified in a TDR. The net present value of the estimated cash flows used to measure impairment is based on model-driven estimates of projected payments, prepayments, defaults and loss-given-default (LGD). Using statistical modeling methodologies, the Corporation estimates the probability that a loan will default prior to maturity based on the attributes of each loan. The factors that are most relevant to the probability of default are the refreshed LTV, or in the case of a subordinated lien, refreshed CLTV, borrower credit score, months since origination (i.e., vintage) and geography. Each of these factors is further broken down by present collection status (whether the loan is current, delinquent, in default or in bankruptcy). Severity (or LGD) is estimated based on the refreshed LTV for first mortgages or CLTV for subordinated liens. The estimates are based on the Corporation's historical experience as adjusted to reflect an assessment of environmental factors that may not be reflected in the historical data, such as changes in real estate values, local and national economies, underwriting standards and the regulatory environment. The probability of default models also incorporate recent experience with modification programs including redefaults subsequent to modification, a loan's default history prior to modification and the change in borrower payments post-modification. At June 30, 2015 and December 31, 2014 , remaining commitments to lend additional funds to debtors whose terms have been modified in a consumer real estate TDR were immaterial. Consumer real estate foreclosed properties totaled $553 million and $630 million at June 30, 2015 and December 31, 2014 . The carrying value of consumer real estate loans, including fully-insured and PCI loans, for which formal foreclosure proceedings were in process as of June 30, 2015 was $6.7 billion . The table below provides the unpaid principal balance, carrying value and related allowance at June 30, 2015 and December 31, 2014 , and the average carrying value and interest income recognized for the three and six months ended June 30, 2015 and 2014 for impaired loans in the Corporation's Consumer Real Estate portfolio segment and includes primarily loans managed by Legacy Assets & Servicing ( LAS) . Certain impaired consumer real estate loans do not have a related allowance as the current valuation of these impaired loans exceeded the carrying value, which is net of previously recorded charge-offs.

During the three and six months ended June 30, 2015 , for the PCI loan portfolio, the Corporation recorded provision expense of $78 million and $28 million with a corresponding increase in the valuation allowance included as part of the allowance for loan and lease losses. This compared to a benefit of $106 million in the provision for credit losses for both of the same periods in 2014 . Write-offs in the PCI loan portfolio totaled $290 million and $578 million with a corresponding decrease in the PCI valuation allowance during the three and six months ended June 30, 2015 compared to $160 million and $551 million for the same periods in 2014 . Write-offs included $65 million and $175 million associated with the sale of PCI loans during the three and six months ended June 30, 2015 compared to $28 million and $186 million for the same periods in 2014 . The valuation allowance associated with the PCI loan portfolio was $1.1 billion and $1.7 billion at June 30, 2015 and December 31, 2014 .

Securitizations and Other Varia

Securitizations and Other Variable Interest Entities	6 Months Ended
	Jun. 30, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Securitizations and Other Variable Interest Entities	NOTE 6 – Securitizations and Other Variable Interest Entities The Corporation utilizes variable interest entities (VIEs) in the ordinary course of business to support its own and its customers' financing and investing needs. The Corporation routinely securitizes loans and debt securities using VIEs as a source of funding for the Corporation and as a means of transferring the economic risk of the loans or debt securities to third parties. The assets are transferred into a trust or other securitization vehicle such that the assets are legally isolated from the creditors of the Corporation and are not available to satisfy its obligations. These assets can only be used to settle obligations of the trust or other securitization vehicle. The Corporation also administers, structures or invests in other VIEs including CDOs, investment vehicles and other entities. For more information on the Corporation's utilization of VIEs, see Note 1 – Summary of Significant Accounting Principles and Note 6 – Securitizations and Other Variable Interest Entities to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . The tables in this Note present the assets and liabilities of consolidated and unconsolidated VIEs at June 30, 2015 and December 31, 2014 , in situations where the Corporation has continuing involvement with transferred assets or if the Corporation otherwise has a variable interest in the VIE. The tables also present the Corporation's maximum loss exposure at June 30, 2015 and December 31, 2014 resulting from its involvement with consolidated VIEs and unconsolidated VIEs in which the Corporation holds a variable interest. The Corporation's maximum loss exposure is based on the unlikely event that all of the assets in the VIEs become worthless and incorporates not only potential losses associated with assets recorded on the Consolidated Balance Sheet but also potential losses associated with off-balance sheet commitments such as unfunded liquidity commitments and other contractual arrangements. The Corporation's maximum loss exposure does not include losses previously recognized through write-downs of assets. The Corporation invests in asset-backed securities (ABS) issued by third-party VIEs with which it has no other form of involvement and enters into certain commercial lending arrangements that may also incorporate the use of VIEs to hold collateral. These securities and loans are included in Note 3 – Securities or Note 4 – Outstanding Loans and Leases . In addition, the Corporation uses VIEs such as trust preferred securities trusts in connection with its funding activities. For additional information, see Note 11 – Long-term Debt to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . The Corporation uses VIEs, such as cash funds managed within Global Wealth & Investment Management (GWIM) , to provide investment opportunities for clients. These VIEs, which are not consolidated by the Corporation, are not included in the tables in this Note. Except as described below and in Note 6 – Securitizations and Other Variable Interest Entities to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K , the Corporation did not provide financial support to consolidated or unconsolidated VIEs during the three and six months ended June 30, 2015 or the year ended December 31, 2014 that it was not previously contractually required to provide, nor does it intend to do so. Mortgage-related Securitizations First-lien Mortgages As part of its mortgage banking activities, the Corporation securitizes a portion of the first-lien residential mortgage loans it originates or purchases from third parties, generally in the form of RMBS guaranteed by government-sponsored enterprises, FNMA and FHLMC (collectively the GSEs), or GNMA primarily in the case of FHA-insured and U.S. Department of Veterans Affairs (VA)-guaranteed mortgage loans. Securitization usually occurs in conjunction with or shortly after origination or purchase and the Corporation may also securitize loans held in its residential mortgage portfolio. In addition, the Corporation may, from time to time, securitize commercial mortgages it originates or purchases from other entities. The Corporation typically services the loans it securitizes. Further, the Corporation may retain beneficial interests in the securitization trusts including senior and subordinate securities and equity tranches issued by the trusts. Except as described below and in Note 7 – Representations and Warranties Obligations and Corporate Guarantees , the Corporation does not provide guarantees or recourse to the securitization trusts other than standard representations and warranties. The table below summarizes select information related to first-lien mortgage securitizations for the three and six months ended June 30, 2015 and 2014 . First-lien Mortgage Securitizations Three Months Ended June 30 Residential Mortgage Agency Non-agency - Subprime Commercial Mortgage (Dollars in millions) 2015 2014 2015 2014 2015 2014 Cash proceeds from new securitizations (1) $ 7,101 $ 7,552 $ — $ 809 $ 2,732 $ 1,508 Gain (loss) on securitizations (2) 184 (21 ) — 49 39 24 Six Months Ended June 30 2015 2014 2015 2014 2015 2014 Cash proceeds from new securitizations (1) $ 14,672 $ 15,018 $ — $ 809 $ 4,888 $ 2,212 Gain (loss) on securitizations (2) 357 (32 ) — 49 32 51 (1) The Corporation transfers residential mortgage loans to securitizations sponsored by the GSEs or GNMA in the normal course of business and receives RMBS in exchange which may then be sold into the market to third-party investors for cash proceeds. (2) A majority of the first-lien residential and commercial mortgage loans securitized are initially classified as LHFS and accounted for under the fair value option. Gains recognized on these LHFS prior to securitization, which totaled $262 million and $431 million , net of hedges, during the three and six months ended June 30, 2015 compared to $185 million and $383 million for the same periods in 2014 , are not included in the table above. In addition to cash proceeds as reported in the table above, the Corporation received securities with an initial fair value of $5.9 billion and $11.3 billion in connection with first-lien mortgage securitizations for the three and six months ended June 30, 2015 compared to $354 million and $860 million for the same periods in 2014 . All of these securities were initially classified as Level 2 assets within the fair value hierarchy. During the three and six months ended June 30, 2015 and 2014 , there were no changes to the initial classification. The Corporation recognizes consumer MSRs from the sale or securitization of first-lien mortgage loans. Servicing fee and ancillary fee income on consumer mortgage loans serviced, including securitizations where the Corporation has continuing involvement, were $353 million and $741 million during the three and six months ended June 30, 2015 compared to $454 million and $948 million for the same periods in 2014 . Servicing advances on consumer mortgage loans, including securitizations where the Corporation has continuing involvement, were $8.9 billion and $10.4 billion at June 30, 2015 and December 31, 2014 . The Corporation may have the option to repurchase delinquent loans out of securitization trusts, which reduces the amount of servicing advances it is required to make. During the three and six months ended June 30, 2015 , $775 million and $1.9 billion of loans were repurchased from first-lien securitization trusts primarily as a result of loan delinquencies or to perform modifications compared to $1.1 billion and $2.4 billion for the same periods in 2014 . The majority of these loans repurchased were FHA-insured mortgages collateralizing GNMA securities. For more information on MSRs, see Note 17 – Mortgage Servicing Rights . During the three months ended June 30, 2015 , the Corporation deconsolidated agency residential mortgage securitization vehicles with total assets of $1.5 billion following the sale of retained interests to third parties, after which the Corporation no longer had the unilateral ability to liquidate the vehicles.

For additional information, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees and Note 17 – Mortgage Servicing Rights . (2) As a holder of these securities, the Corporation receives scheduled principal and interest payments. During the three and six months ended June 30, 2015 and 2014 , there were no OTTI losses recorded on those securities classified as AFS debt securities. (3) Not included in the table above are all other assets of $180 million and $635 million , representing the unpaid principal balance of mortgage loans eligible for repurchase from unconsolidated residential mortgage securitization vehicles, principally guaranteed by GNMA, and all other liabilities of $180 million and $635 million , representing the principal amount that would be payable to the securitization vehicles if the Corporation was to exercise the repurchase option, at June 30, 2015 and December 31, 2014 . (4) Principal balance outstanding includes loans the Corporation transferred with which it has continuing involvement, which may include servicing the loans. Home Equity Loans The Corporation retains interests in home equity securitization trusts to which it transferred home equity loans. These retained interests include senior and subordinate securities and residual interests. In addition, the Corporation may be obligated to provide subordinate funding to the trusts during a rapid amortization event. The Corporation typically services the loans in the trusts. Except as described below and in Note 7 – Representations and Warranties Obligations and Corporate Guarantees , the Corporation does not provide guarantees or recourse to the securitization trusts other than standard representations and warranties. There were no securitizations of home equity loans during the three and six months ended June 30, 2015 and 2014 , and all of the home equity trusts that hold revolving home equity lines of credit have entered the rapid amortization phase. The table below summarizes select information related to home equity loan securitization trusts in which the Corporation held a variable interest at June 30, 2015 and December 31, 2014 .

The maximum loss exposure in the table above includes the Corporation's obligation to provide subordinate funding to the consolidated and unconsolidated home equity loan securitizations that have entered a rapid amortization period. During this period, cash payments from borrowers are accumulated to repay outstanding debt securities and the Corporation continues to make advances to borrowers when they draw on their lines of credit. At June 30, 2015 and December 31, 2014 , home equity loan securitizations in rapid amortization for which the Corporation has a subordinate funding obligation, including both consolidated and unconsolidated trusts, had $5.7 billion and $6.3 billion of trust certificates outstanding. This amount is significantly greater than the amount the Corporation expects to fund. The charges that will ultimately be recorded as a result of the rapid amortization events depend on the undrawn available credit on the home equity lines, which totaled $27 million and $39 million at June 30, 2015 and December 31, 2014 , as well as performance of the loans, the amount of subsequent draws and the timing of related cash flows. Credit Card Securitizations The Corporation securitizes originated and purchased credit card loans. The Corporation's continuing involvement with the securitization trust includes servicing the receivables, retaining an undivided interest (seller's interest) in the receivables, and holding certain retained interests including senior and subordinate securities, subordinate interests in accrued interest and fees on the securitized receivables, and cash reserve accounts. The seller's interest in the trust, which is pari passu to the investors' interest, is classified in loans and leases. The table below summarizes select information related to consolidated credit card securitization trusts in which the Corporation held a variable interest at June 30, 2015 and December 31, 2014 .

(2) At June 30, 2015 and December 31, 2014 , all other assets included restricted cash, certain short-term investments, and unbilled accrued interest and fees. During the three and six months ended June 30, 2015 , $1.2 billion and $2.3 billion of new senior debt securities were issued to third-party investors from the credit card securitization trust compared to $1.3 billion and $3.0 billion for the same periods in 2014 . The Corporation held subordinate securities issued by the credit card securitization trust with a notional principal amount of $7.7 billion and $7.4 billion at June 30, 2015 and December 31, 2014 . These securities serve as a form of credit enhancement to the senior debt securities and have a stated interest rate of zero percent . There were $194 million and $371 million of these subordinate securities issued during the three and six months ended June 30, 2015 compared to $202 million and $484 million for the same periods in 2014 . Other Asset-backed Securitizations Other asset-backed securitizations include resecuritization trusts, municipal bond trusts, and automobile and other securitization trusts.

During the three and six months ended June 30, 2015 and 2014 , there were no OTTI losses recorded on those securities classified as AFS debt securities. (2) The retained senior and subordinate securities were valued using quoted market prices or observable market inputs (Level 2 of the fair value hierarchy). (3) The retained residual interests are carried at fair value which was derived using model valuations (Level 2 of the fair value hierarchy). (4) Total assets include loans the Corporation transferred with which the Corporation has continuing involvement, which may include servicing the loan. Resecuritization Trusts The Corporation transfers existing securities, typically MBS, into resecuritization vehicles at the request of customers seeking securities with specific characteristics. The Corporation may also resecuritize securities within its investment portfolio for purposes of improving liquidity and capital, and managing credit or interest rate risk. Generally, there are no significant ongoing activities performed in a resecuritization trust and no single investor has the unilateral ability to liquidate the trust. The Corporation resecuritized $6.9 billion and $13.0 billion of securities during the three and six months ended June 30, 2015 compared to $3.9 billion and $6.1 billion for the same periods in 2014 . Securities transferred into resecuritization vehicles during the three and six months ended June 30, 2015 and 2014 were classified as trading account assets. As such, changes in fair value were recorded in trading account profits prior to the resecuritization and no gain or loss on sale was recorded. Municipal Bond Trusts The Corporation administers municipal bond trusts that hold highly-rated, long-term, fixed-rate municipal bonds. The trusts obtain financing by issuing floating-rate trust certificates that reprice on a weekly or other short-term basis to third-party investors. The Corporation may transfer assets into the trusts and may also serve as remarketing agent and/or liquidity provider for the trusts. The floating-rate investors have the right to tender the certificates at specified dates. Should the Corporation be unable to remarket the tendered certificates, it may be obligated to purchase them at par under standby liquidity facilities. The Corporation also provides credit enhancement to investors in certain municipal bond trusts whereby the Corporation guarantees the payment of interest and principal on floating-rate certificates issued by these trusts in the event of default by the issuer of the underlying municipal bond. The Corporation's liquidity commitments to unconsolidated municipal bond trusts, including those for which the Corporation was transferor, totaled $1.8 billion and $2.1 billion at June 30, 2015 and December 31, 2014 . The weighted-average remaining life of bonds held in the trusts at June 30, 2015 was 7.1 years. There were no material write-downs or downgrades of assets or issuers during the three and six months ended June 30, 2015 and 2014 . Automobile and Other Securitization Trusts The Corporation transfers automobile and other loans into securitization trusts, typically to improve liquidity or manage credit risk. At June 30, 2015 and December 31, 2014 , the Corporation serviced assets or otherwise had continuing involvement with automobile and other securitization trusts with outstanding balances of $440 million and $1.9 billion , including trusts collateralized by automobile loans of $238 million and $400 million , student loans of $0 and $609 million , and other loans of $202 million and $876 million . Other Variable Interest Entities The table below summarizes select information related to other VIEs in which the Corporation held a variable interest at June 30, 2015 and December 31, 2014 .

Customer Vehicles Customer vehicles include credit-linked, equity-linked and commodity-linked note vehicles, repackaging vehicles, and asset acquisition vehicles, which are typically created on behalf of customers who wish to obtain market or credit exposure to a specific company, index, commodity or financial instrument. The Corporation may transfer assets to and invest in securities issued by these vehicles. The Corporation typically enters into credit, equity, interest rate, commodity or foreign currency derivatives to synthetically create or alter the investment profile of the issued securities. The Corporation's maximum loss exposure to consolidated and unconsolidated customer vehicles totaled $3.4 billion and $4.7 billion at June 30, 2015 and December 31, 2014 , including the notional amount of derivatives to which the Corporation is a counterparty, net of losses previously recorded, and the Corporation's investment, if any, in securities issued by the vehicles. The maximum loss exposure has not been reduced to reflect the benefit of offsetting swaps with the customers or collateral arrangements. The Corporation also had liquidity commitments, including written put options and collateral value guarantees, with certain unconsolidated vehicles of $655 million and $658 million at June 30, 2015 and December 31, 2014 , that are included in the table above. Collateralized Debt Obligation Vehicles The Corporation receives fees for structuring CDO vehicles, which hold diversified pools of fixed-income securities, typically corporate debt or ABS, which they fund by issuing multiple tranches of debt and equity securities. Synthetic CDOs enter into a portfolio of CDS to synthetically create exposure to fixed-income securities. CLOs, which are a subset of CDOs, hold pools of loans, typically corporate loans. CDOs are typically managed by third-party portfolio managers. The Corporation typically transfers assets to these CDOs, holds securities issued by the CDOs and may be a derivative counterparty to the CDOs, including a CDS counterparty for synthetic CDOs. The Corporation has also entered into total return swaps with certain CDOs whereby the Corporation absorbs the economic returns generated by specified assets held by the CDO. The Corporation's maximum loss exposure to consolidated and unconsolidated CDOs totaled $628 million and $780 million at June 30, 2015 and December 31, 2014 . This exposure is calculated on a gross basis and does not reflect any benefit from insurance purchased from third parties. At June 30, 2015 , the Corporation had $998 million of aggregate liquidity exposure, included in the Other VIEs table net of previously recorded losses, to unconsolidated CDOs which hold senior CDO debt securities or other debt securities on the Corporation's behalf. For additional information, see Note 10 – Commitments and Contingencies . Investment Vehicles The Corporation sponsors, invests in or provides financing, which may be in connection with the sale of assets, to a variety of investment vehicles that hold loans, real estate, debt securities or other financial instruments and are designed to provide the desired investment profile to investors or the Corporation. At June 30, 2015 and December 31, 2014 , the Corporation's consolidated investment vehicles had total assets of $1.2 billion and $1.1 billion . The Corporation also held investments in unconsolidated vehicles with total assets of $9.8 billion and $11.2 billion at June 30, 2015 and December 31, 2014 . The Corporation's maximum loss exposure associated with both consolidated and unconsolidated investment vehicles totaled $3.9 billion and $5.1 billion at June 30, 2015 and December 31, 2014 comprised primarily of on-balance sheet assets less non-recourse liabilities. The Corporation transferred servicing advance receivables to independent third parties in connection with the sale of MSRs. Portions of the receivables were transferred into unconsolidated securitization trusts. The Corporation retained senior interests in such receivables with a maximum loss exposure and funding obligation of $250 million and $660 million , including a funded balance of $138 million and $431 million at June 30, 2015 and December 31, 2014 , which were classified in other debt securities carried at fair value. Leveraged Lease Trusts The Corporation's net investment in consolidated leveraged lease trusts totaled $3.1 billion and $3.3 billion at June 30, 2015 and December 31, 2014 . The trusts hold long-lived equipment such as rail cars, power generation and distribution equipment, and commercial aircraft. The Corporation structures the trusts and holds a significant residual interest. The net investment represents the Corporation's maximum loss exposure to the trusts in the unlikely event that the leveraged lease investments become worthless. Debt issued by the leveraged lease trusts is non-recourse to the Corporation. Real Estate Vehicles The Corporation held investments in unconsolidated real estate vehicles with total assets of $6.2 billion at both June 30, 2015 and December 31, 2014 , which primarily consisted of investments in unconsolidated limited partnerships that finance the construction and rehabilitation of affordable rental housing and commercial real estate. An unrelated third party is typically the general partner and has control over the significant activities of the partnership. The Corporation earns a return primarily through the receipt of tax credits allocated to the real estate projects. The Corporation's risk of loss is mitigated by policies requiring that the project qualify for the expected tax credits prior to making its investment. The Corporation may from time to time be asked to invest additional amounts to support a troubled project. Such additional investments have not been and are not expected to be significant.

Representations and Warranties Obligations and Corporate Guarantees [Abstract]
Representations and Warranties Obligations and Corporate Guarantees	NOTE 7 – Representations and Warranties Obligations and Corporate Guarantees Background The Corporation securitizes first-lien residential mortgage loans generally in the form of RMBS guaranteed by the GSEs or by GNMA in the case of FHA-insured, VA-guaranteed and Rural Housing Service-guaranteed mortgage loans, and sells pools of first-lien residential mortgage loans in the form of whole loans. In addition, in prior years, legacy companies and certain subsidiaries sold pools of first-lien residential mortgage loans and home equity loans as private-label securitizations (in certain of these securitizations, monoline insurers or other financial guarantee providers insured all or some of the securities) or in the form of whole loans. In connection with these transactions, the Corporation or certain of its subsidiaries or legacy companies made various representations and warranties. These representations and warranties, as set forth in the agreements, related to, among other things, the ownership of the loan, the validity of the lien securing the loan, the absence of delinquent taxes or liens against the property securing the loan, the process used to select the loan for inclusion in a transaction, the loan's compliance with any applicable loan criteria, including underwriting standards, and the loan's compliance with applicable federal, state and local laws. Breaches of these representations and warranties have resulted in and may continue to result in the requirement to repurchase mortgage loans or to otherwise make whole or provide other remedies to the GSEs, U.S. Department of Housing and Urban Development (HUD) with respect to FHA-insured loans, VA, whole-loan investors, securitization trusts, monoline insurers or other financial guarantors as applicable (collectively, repurchases). In all such cases, subsequent to repurchasing the loan, the Corporation would be exposed to any credit loss on the repurchased mortgage loans after accounting for any mortgage insurance (MI) or mortgage guarantee payments that it may receive. Subject to the requirements and limitations of the applicable sales and securitization agreements, including the applicable statute of limitations for contractual claims, these representations and warranties can be enforced by the GSEs, HUD, VA, the whole-loan investor, the securitization trustee or others as provided by the applicable agreement or, in certain first-lien and home equity securitizations where monoline insurers or other financial guarantee providers have insured all or some of the securities issued, by the monoline insurer or other financial guarantor, where the contract so provides. In the case of private-label securitizations, the applicable agreements may permit investors, which in some instances include the GSEs, with sufficient holdings to direct or influence action by the securitization trustee. In the case of loans sold to parties other than the GSEs or GNMA, the contractual liability to repurchase typically arises only if there is a breach of the representations and warranties that materially and adversely affects the interest of the investor, or investors, or of the monoline insurer or other financial guarantor (as applicable) in the loan. Contracts with the GSEs do not contain equivalent language. The Corporation believes that the longer a loan performs prior to default, the less likely it is that an alleged underwriting breach of representations and warranties would have a material impact on the loan's performance. Currently, the volume of unresolved repurchase claims from the FHA and VA for loans in GNMA-guaranteed securities is not significant because the claims are typically resolved promptly. New York Court Decision on Statute of Limitations On June 11, 2015, the New York Court of Appeals, New York's highest appellate court , issued its opinion in ACE Securities Corp. v. DB Structured Products, Inc. (ACE), holding that, under New York law the six -year statute of limitations starts to run at the time the representations and warranties are made , not the date when the repurchase demand was denied. In addition, the Court of Appeals held that compliance with the contractual notice and cure period was a pre-condition to filing suit, and claims that did not comply with such contractual requirements prior to the expiration of the statute of limitations period were invalid. While no entity affiliated with the Corporation was a party to this litigation, the vast majority of the private-label RMBS trusts into which entities affiliated with the Corporation sold loans and made representations and warranties are governed by New York law, and the ACE decision should therefore apply to representations and warranties claims and litigation brought on those RMBS trusts. A significant number of representations and warranties claims and lawsuits brought against the Corporation have involved or may involve claims where the statute of limitations has expired under the ACE decision and are therefore time-barred. The Corporation treats time-barred claims as resolved and no longer outstanding; however, while post-ACE case law is in very early stages, investors or trustees may seek to distinguish certain aspects of the ACE ruling or to assert other claims seeking to avoid the impact of the ACE ruling. The impact on the Corporation, if any, of such claims is unclear at this time. For more information on repurchase demands, see Unresolved Repurchase Claims in this Note. The liability for representations and warranties exposures and the corresponding estimated range of possible loss are based upon currently available information, significant judgment, and a number of factors and assumptions, including those discussed in Liability for Representations and Warranties and Corporate Guarantees in this Note, that are subject to change. Changes to any one of these factors could significantly impact the liability for representations and warranties exposures and the corresponding estimated range of possible loss and could have a material adverse impact on the Corporation's results of operations for any particular period. Given that these factors vary by counterparty, the Corporation analyzes representations and warranties obligations based on the specific counterparty, or type of counterparty, with whom the sale was made. For additional information, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . Settlement Actions The Corporation has vigorously contested any request for repurchase where it has concluded that a valid basis for repurchase does not exist and will continue to do so in the future. However, in an effort to resolve legacy mortgage-related issues, the Corporation has reached bulk settlements, including various settlements with the GSEs, and including settlement amounts which have been significant, with counterparties in lieu of a loan-by-loan review process. These bulk settlements generally did not cover all transactions with the relevant counterparties or all potential claims that may arise, including in some instances securities law, fraud and servicing claims, which may be addressed separately. The Corporation's liability in connection with the transactions and claims not covered by these settlements could be material to the Corporation's results of operations or cash flows for any particular reporting period. The Corporation may reach other settlements in the future if opportunities arise on terms it believes to be advantageous. However, there can be no assurance that the Corporation will reach future settlements or, if it does, that the terms of past settlements can be relied upon to predict the terms of future settlements. The following provides a summary of the settlement with Bank of New York Mellon (BNY Mellon), which remains subject to the satisfaction of certain conditions. For a discussion of other large settlement actions entered into by the Corporation in recent years, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . Settlement with the Bank of New York Mellon, as Trustee On March 5, 2015, the New York Appellate Division, First Department issued an order unanimously approving the BNY Mellon Settlement in all respects. The deadline for further appeal has passed. On April 22, 2015, the New York County Supreme Court entered final judgment approving the settlement. The BNY Mellon Settlement remains subject to certain conditions, including that an Internal Revenue Service private letter ruling be obtained confirming that the settlement will not impact the real estate mortgage investment conduit tax status of the trusts and that certain state tax opinions be obtained. If those conditions are not satisfied by December 31, 2015, the Corporation and Countrywide may withdraw from the BNY Mellon Settlement, if the Trustee consents. If the conditions are not satisfied, or if the Corporation and Countrywide withdraw from the BNY Mellon Settlement in accordance with its terms, the Corporation's future representations and warranties losses could be substantially different from existing accruals and the estimated range of possible loss over existing accruals described under Private-label Securitizations and Whole-loan Sales Experience in this Note. For a description of the BNY Mellon Settlement, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K and Note 7 – Representations and Warranties Obligations and Corporate Guarantees of the Corporation’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2015 . Unresolved Repurchase Claims Unresolved representations and warranties repurchase claims represent the notional amount of repurchase claims made by counterparties, typically the outstanding principal balance or the unpaid principal balance at the time of default . In the case of first-lien mortgages, the claim amount is often significantly greater than the expected loss amount due to the benefit of collateral and, in some cases , MI or mortgage guarantee payments. Claims received from a counterparty remain outstanding until the underlying loan is repurchased, the claim is rescinded by the counterparty, the Corporation determines that the applicable statute of limitations has expired (beginning in this quarter, this is determined, where applicable, in accordance with the ACE decision), or representations and warranties claims with respect to the applicable trust are settled, and fully and finally released. When a claim is denied and the Corporation does not receive a response from the counterparty, the claim remains in the unresolved repurchase claims balance until resolution in one of the ways described above . Certain of the claims that have been received are duplicate claims which represent more than one claim outstanding related to a particular loan, typically as the result of bulk claims submitted without individual file reviews. The table below presents unresolved repurchase claims at June 30, 2015 and December 31, 2014 . The unresolved repurchase claims include only claims where the Corporation believes that the counterparty has the contractual right to submit claims. For additional information, see Private-label Securitizations and Whole-loan Sales Experience in this Note . Unresolved Repurchase Claims by Counterparty and Product Type (Dollars in millions) June 30 December 31 2014 (1) By counterparty Private-label securitization trustees, whole-loan investors, including third-party securitization sponsors and other (2, 3) $ 19,431 $ 24,489 Monolines (4) 1,631 1,546 GSEs 31 59 Total gross claims (3) 21,093 26,094 Duplicate claims (5) (2,622 ) (3,248 ) Total unresolved repurchase claims by counterparty, net of duplicate claims $ 18,471 $ 22,846 By product type Prime loans $ 200 $ 587 Alt-A 1,208 2,397 Home equity 2,195 2,485 Pay option 4,986 6,294 Subprime 12,495 14,121 Other 9 210 Total (3) 21,093 26,094 Duplicate claims (5) (2,622 ) (3,248 ) Total unresolved repurchase claims by product type, net of duplicate claims $ 18,471 $ 22,846 (1) The December 31, 2014 amounts have been updated to reflect additional claims submitted from a single monoline, currently pursuing litigation, served in the fourth quarter of 2014, and addressed by the Corporation in 2015 pursuant to an existing litigation schedule. For more information on bond insurance litigation, see Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . (2) The total notional amount of unresolved repurchase claims does not include repurchase claims related to the trusts covered by the BNY Mellon Settlement. (3) Includes $12.0 billion and $14.1 billion of claims based on individual file reviews and $7.4 billion and $10.4 billion of claims submitted without individual file reviews at June 30, 2015 and December 31, 2014 . (4) At June 30, 2015 , substantially all of the unresolved monoline claims are currently the subject of litigation with a single monoline insurer and predominately pertain to second-lien loans. (5) Represents more than one claim outstanding related to a particular loan, typically as the result of bulk claims submitted without individual file reviews. The June 30, 2015 and December 31, 2014 amounts include approximately $2.5 billion and $2.9 billion of duplicate claims related to private-label investors submitted without individual loan file reviews. During the three and six months ended June 30, 2015 , the Corporation received $224 million and $3.6 billion in new repurchase claims, primarily $3.2 billion in claims submitted without individual loan file reviews. During the three and six months ended June 30, 2015 , $7.3 billion and $7.5 billion in claims, net of duplicate claims, were resolved, including $7.1 billion which are deemed resolved as a result of the ACE decision. In addition to the unresolved repurchase claims in the Unresolved Repurchase Claims by Counterparty and Product Type table, the Corporation has received notifications from sponsors of third-party securitizations with whom the Corporation engaged in whole-loan transactions indicating that the Corporation may have indemnity obligations with respect to loans for which the Corporation has not received a repurchase request . These notifications totaled $2.0 billion at both June 30, 2015 and December 31, 2014 . The Corporation has considered this risk in the estimated range of possible loss . The Corporation also from time to time receives correspondence purporting to raise representations and warranties breach issues from entities that do not have contractual standing or ability to bring such claims . The Corporation believes such communications to be procedurally and/or substantively invalid, and generally does not respond . The presence of repurchase claims on a given trust, receipt of notices of indemnification obligations and receipt of other communications, as discussed above, are all factors that inform the Corporation's liability for representations and warranties and the corresponding estimated range of possible loss . Government-sponsored Enterprises Experience As a result of various bulk settlements with the GSEs, the Corporation has resolved substantially all outstanding and potential representations and warranties repurchase claims on whole loans sold by legacy Bank of America and Countrywide to FNMA and FHLMC through June 30, 2012 and December 31, 2009, respectively. After these settlements, the Corporation's exposure to representations and warranties liability for loans originated prior to 2009 and sold to the GSEs is limited to loans with an original principal balance of $18.3 billion and loans with certain characteristics excluded from the settlements that the Corporation does not believe will be material, such as certain specified violations of the GSEs' charters, fraud and title defects. As of June 30, 2015 , of the $18.3 billion , approximately $15.9 billion in principal has been paid and $986 million in principal has defaulted or was severely delinquent. At June 30, 2015 , the notional amount of unresolved repurchase claims submitted by the GSEs was $25 million related to these vintages. Private-label Securitizations and Whole-loan Sales Experience In prior years, legacy companies and certain subsidiaries sold pools of first-lien residential mortgage loans and home equity loans as private-label securitizations or in the form of whole loans. In connection with these transactions, the Corporation or certain of its subsidiaries or legacy companies made various representations and warranties. When the Corporation provided representations and warranties in connection with the sale of whole loans, the whole-loan investors may retain the right to make repurchase claims even when the loans were aggregated with other collateral into private-label securitizations sponsored by the whole-loan investors. In other third-party securitizations, the whole-loan investors' rights to enforce the representations and warranties were transferred to the securitization trustees. Private-label securitization investors generally do not have the contractual right to demand repurchase of loans directly or the right to access loan files directly. In private-label securitizations, the applicable contracts provide that investors must meet certain presentation thresholds to issue a binding direction to a trustee to assert repurchase claims. However, in certain circumstances, the Corporation believes that trustees have presented repurchase claims without requiring investors to meet contractual voting rights thresholds. New private-label claims are primarily related to repurchase requests received from trustees for private-label securitization transactions not included in the BNY Mellon Settlement . At June 30, 2015 and December 31, 2014 , for loans originated between 2004 and 2008 , the notional amount of unresolved repurchase claims, net of duplicate claims, submitted by private-label securitization trustees, whole-loan investors, including third-party securitization sponsors, and others was $16.8 billion and $21.2 billion . These repurchase claims at June 30, 2015 exclude claims in the amount of $7.1 billion , net of duplicate claims, where the statute of limitations has expired without litigation being commenced (beginning in this quarter, this is determined, where applicable, in accordance with the ACE decision). At December 31, 2014 , time-barred claims of $5.2 billion , net of duplicate claims, were included in unresolved repurchase claims . The notional amount of unresolved repurchase claims at both June 30, 2015 and December 31, 2014 includes $3.5 billion of claims, net of duplicate claims, related to loans in specific private-label securitization groups or tranches where the Corporation owns substantially all of the outstanding securities. The decrease in the notional amount of outstanding unresolved repurchase claims, net of duplicate claims, in the three and six months ended June 30, 2015 is primarily due to the impact of the ACE decision. Excluding time-barred claims that were treated as outstanding at December 31, 2014, the remaining outstanding unresolved repurchase claims are driven by: (1) continued submission of claims by private-label securitization trustees, (2) the level of detail, support and analysis accompanying such claims, which impact overall claim quality and, therefore, claims resolution and (3) the lack of an established process to resolve disputes related to these claims . For example, claims submitted without individual file reviews generally lack the level of detail and analysis of individual loans that is necessary to evaluate a claim . The Corporation reviews properly presented repurchase claims on a loan-by-loan basis. Claims that are time-barred under the ACE decision are treated as resolved. If, after the Corporation's review of timely claims, it does not believe a claim is valid, it will deny the claim and generally indicate a reason for the denial. When the counterparty agrees with the Corporation's denial of the claim, the counterparty may rescind the claim. When there is disagreement as to the resolution of the claim, meaningful dialogue and negotiation between the parties are generally necessary to reach a resolution on an individual claim. When a claim has been denied and the Corporation does not hear from the counterparty for six months, the Corporation views these claims as inactive; however, they remain in the outstanding claims balance until resolution in one of the manners described above. In the case of private-label securitization trustees and third-party sponsors, there is currently no established process in place for the parties to reach a conclusion on an individual loan if there is a disagreement on the resolution of the claim. The Corporation has performed an initial review with respect to substantially all of these claims and, although the Corporation does not believe a valid basis for repurchase has been established by the claimant, it considers such claims activity in the computation of its liability for representations and warranties. Parties seeking to pursue claims and/or lawsuits with respect to trusts where the statute of limitations for representations and warranties claims against the sponsor has expired may pursue other claims against the sponsor and/or assert claims against other contractual parties. For example, institutional investors have filed lawsuits against trustees based upon alleged contractual, statutory and tort theories of liability and alleging failure to pursue representations and warranties claims and servicer defaults. The impact on the Corporation, if any, of such legal theories or claims is unclear at this time. Monoline Insurers Experience For a description of the Corporation's experience with monoline insurers, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees and Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . Open Mortgage Insurance Rescission Notices In addition to repurchase claims, the Corporation receives notices from mortgage insurance companies of claim denials, cancellations or coverage rescission (collectively, MI rescission notices). For more information, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . Liability for Representations and Warranties and Corporate Guarantees The liability for representations and warranties and corporate guarantees is included in accrued expenses and other liabilities on the Consolidated Balance Sheet and the related provision is included in mortgage banking income in the Consolidated Statement of Income . The liability for representations and warranties is established when those obligations are both probable and reasonably estimable. The Corporation's liability and corresponding estimated range of possible loss at June 30, 2015 for obligations under representations and warranties given to the GSEs considers a number of factors. These include the Corporation's experience related to actual defaults, projected future defaults, historical loss experience, estimated home prices and other economic conditions. In addition, the liability for representations and warranties and corporate guarantees and corresponding estimated range of possible loss consider such factors as the number of payments made by the borrower prior to default as well as certain other assumptions and judgmental factors. The Corporation's non-GSE representations and warranties liability and the corresponding estimated range of possible loss at June 30, 2015 considers, among other things, implied repurchase experience based on the BNY Mellon Settlement, adjusted to reflect differences between the trusts covered by the settlement and the remainder of the population of private-label securitizations where the statute of limitations for representations and warranties claims has not expired, and assumes that, for those trusts where timely representations and warranties claims exist or are still possible, the conditions to the BNY Mellon Settlement will be met. Since the securitization trusts that were included in the BNY Mellon Settlement differ from those that were not included in the BNY Mellon Settlement, the Corporation adjusted the repurchase experience implied in the settlement in order to determine the non-GSE representations and warranties liability and the corresponding estimated range of possible loss. The judgmental adjustments made include consideration of the differences in the mix of products in the subject securitizations, loan originator, likelihood of claims expected, the differences in the number of payments that the borrower has made prior to default and the sponsor of the securitizations. Where relevant, the Corporation also considers more recent experience, such as claim activity, notification of potential indemnification obligations, its experience with various counterparties, the ACE decision summarized above and other facts and circumstances, such as bulk settlements, as the Corporation believes appropriate. A factor that impacts the non-GSE representations and warranties liability and the portion of the estimated range of possible loss corresponding to non-GSE representations and warranties exposures is the likelihood that timely claims will be presented, which is impacted by a number of factors, including whether the applicable statute of limitations has lapsed, as well as the contractual provisions that investors meet certain presentation thresholds under the non-GSE securitization agreements. A securitization trustee may investigate or demand repurchase on its own action, and most agreements contain a presentation threshold, for example 25 percent of the voting rights per trust, that allows investors to declare a servicing event of default under certain circumstances or to request certain action, such as requesting loan files, that the trustee may choose to accept and follow, exempt from liability, provided the trustee is acting in good faith. If there is an uncured servicing event of default and the trustee fails to bring suit during a 60-day period, then, under most agreements, investors may file suit. In addition to this, most agreements allow investors to direct the securitization trustee to investigate loan files or demand the repurchase of loans if security holders hold a specified percentage, for example, 25 percent , of the voting rights of each tranche of the outstanding securities. However, in certain circumstances, the Corporation believes that trustees have presented repurchase claims without requiring investors to meet contractual voting rights thresholds. The population of private-label securitizations included in the BNY Mellon Settlement encompasses almost all Countrywide first-lien private-label securitizations including loans originated principally between 2004 and 2008 . For the remainder of the population of private-label securitizations, claimants have come forward on certain securitizations and the Corporation believes it is probable that other claimants may continue to come forward with claims that meet the contractual requirements of other securitizations. For more information on the representations and warranties liability and the corresponding estimated range of possible loss, see Estimated Range of Possible Loss in this Note. The table below presents a rollforward of the liability for representations and warranties and corporate guarantees. Representations and Warranties and Corporate Guarantees Three Months Ended June 30 Six Months Ended June 30 (Dollars in millions) 2015 2014 2015 2014 Liability for representations and warranties and corporate guarantees, beginning of period $ 11,992 $ 13,411 $ 12,081 $ 13,282 Additions for new sales 2 2 3 5 Net reductions (233 ) (1,417 ) (407 ) (1,469 ) Provision (benefit) (205 ) 88 (121 ) 266 Liability for representations and warranties and corporate guarantees, June 30 $ 11,556 $ 12,084 $ 11,556 $ 12,084 The representations and warranties liability represents the Corporation's best estimate of probable incurred losses as of June 30, 2015 . However, it is reasonably possible that future representations and warranties losses may occur in excess of the amounts recorded for these exposures. The benefit in the provision for representations and warranties for the three and six months compared to a provision in the same periods in 2014 was primarily driven by the impact of the ACE decision , as time-barred claims are now treated as resolved . Estimated Range of Possible Loss The Corporation currently estimates that the range of possible loss for representations and warranties exposures could be up to $2 billion over existing accruals at June 30, 2015 compared to up to $4 billion at March 31, 2015 . The decrease in the estimated range of possible loss is primarily driven by the impact of the ACE decision on the Corporation's estimate of ongoing representations and warranties risk . The Corporation treats claims that are time-barred under the ACE decision as resolved and no longer considers such claims in the estimated range of possible loss. The estimated range of possible loss reflects principally non-GSE exposures. It represents a reasonably possible loss, but does not represent a probable loss, and is based on currently available information, significant judgment and a number of assumptions that are subject to change. The liability for representations and warranties exposures and the corresponding estimated range of possible loss do not consider losses related to servicing (except as such losses are included as potential costs of the BNY Mellon Settlement), including foreclosure and related costs, fraud, indemnity, or claims (including for RMBS) related to securities law or monoline insurance litigation. Losses with respect to one or more of these matters could be material to the Corporation's results of operations or cash flows for any particular reporting period. Future provisions and/or ranges of possible loss for representations and warranties may be significantly impacted if actual experiences are different from the Corporation's assumptions in predictive models, including, without limitation, ultimate resolution of the BNY Mellon Settlement, the actual repurchase rates on loans in trusts not settled as part of the BNY Mellon settlement which may be different than the implied repurchase experience, estimated MI rescission rates, economic conditions, estimated home prices, consumer and counterparty behavior, the applicable statute of limitations, potential indemnity obligations to third parties to whom the Corporation has sold loans subject to representations and warranties and a variety of other judgmental factors. Adverse developments with respect to one or more of the assumptions underlying the liability for representations and warranties and the corresponding estimated range of possible loss could result in significant increases to future provisions and/or the estimated range of possible loss. Finally, although the Corporation believes that the representations and warranties typically given in non-GSE transactions are less rigorous than those given in GSE transactions, the Corporation does not have sufficient experience resolving loan-level claims in non-GSE transactions to measure the impact of these differences on the probability that a loan will be required to be repurchased. Cash Payments The Loan Repurchases and Indemnification Payments table presents first-lien and home equity loan repurchases and indemnification payments made by the Corporation to reimburse the investor or securitization trust for losses they incurred, and to resolve repurchase claims. Cash paid for loan repurchases includes the unpaid principal balance of the loan plus past due interest. The amount of loss for loan repurchases is reduced by the fair value of the underlying loan collateral. The repurchase of loans and indemnification payments related to first-lien and home equity repurchase claims generally resulted from material breaches of representations and warranties related to the loans' material compliance with the

The Corporation offsets repurchase and resale transactions with the same counterparty on the Consolidated Balance Sheet where it has such a legally enforceable master netting agreement and the transactions have the same maturity date. Substantially all securities borrowing and lending activities are transacted under legally enforceable master securities lending agreements that give the Corporation, in the event of default by the counterparty, the right to liquidate securities held and to offset receivables and payables with the same counterparty. The Corporation offsets securities borrowing and lending transactions with the same counterparty on the Consolidated Balance Sheet where it has such a legally enforceable master netting agreement and the transactions have the same maturity date. The Securities Financing Agreements table presents securities financing agreements included on the Consolidated Balance Sheet in federal funds sold and securities borrowed or purchased under agreements to resell, and in federal funds purchased and securities loaned or sold under agreements to repurchase at June 30, 2015 and December 31, 2014 . Balances are presented on a gross basis, prior to the application of counterparty netting. Gross assets and liabilities are adjusted on an aggregate basis to take into consideration the effects of legally enforceable master netting agreements. For more information on the offsetting of derivatives, see Note 2 – Derivatives . The "Other" amount in the table, which is included on the Consolidated Balance Sheet in accrued expenses and other liabilities, relates to transactions where the Corporation acts as the lender in a securities lending agreement and receives securities that can be pledged or sold as collateral. In these transactions, the Corporation recognizes an asset at fair value, representing the securities received, and a liability, representing the obligation to return those securities. Gross assets and liabilities in the table include activity where uncertainty exists as to the enforceability of certain master netting agreements under bankruptcy laws in some countries or industries and, accordingly, these are reported on a gross basis. The column titled "Financial Instruments" in the table includes securities collateral received or pledged under repurchase or securities lending agreements where there is a legally enforceable master netting agreement. These amounts are not offset on the Consolidated Balance Sheet, but are shown as a reduction to the net balance sheet amount in this table to derive a net asset or liability. Securities collateral received or pledged where the legal enforceability of the master netting agreements is not certain is not included.

The Corporation is required to post collateral with a market value equal to or in excess of the principal amount borrowed under repurchase agreements. For securities loaned transactions, the Corporation receives collateral in the form of cash, letters of credit or other securities. To ensure that the market value of the underlying collateral remains sufficient, collateral is generally valued daily and the Corporation may be required to deposit additional collateral or may receive or return collateral pledged when appropriate. Repurchase agreements and securities loaned transactions are generally either overnight, continuous (i.e., no stated term) or short-term. The Corporation manages liquidity risks related to these agreements by sourcing funding from a diverse group of counterparties, providing a range of securities collateral and pursuing longer durations, when appropriate.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 10 – Commitments and Contingencies In the normal course of business, the Corporation enters into a number of off-balance sheet commitments. These commitments expose the Corporation to varying degrees of credit and market risk and are subject to the same credit and market risk limitation reviews as those instruments recorded on the Consolidated Balance Sheet. For more information on commitments and contingencies, see Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . Credit Extension Commitments The Corporation enters into commitments to extend credit such as loan commitments, standby letters of credit (SBLCs) and commercial letters of credit to meet the financing needs of its customers. The table below includes the notional amount of unfunded legally binding lending commitments net of amounts distributed (e.g., syndicated) to other financial institutions of $13.7 billion and $15.7 billion at June 30, 2015 and December 31, 2014 . At June 30, 2015 , the carrying value of these commitments, excluding commitments accounted for under the fair value option, was $606 million , including deferred revenue of $18 million and a reserve for unfunded lending commitments of $588 million . At December 31, 2014 , the comparable amounts were $546 million , $18 million and $528 million , respectively. The carrying value of these commitments is classified in accrued expenses and other liabilities on the Consolidated Balance Sheet. The table below also includes the notional amount of commitments of $8.1 billion and $9.9 billion at June 30, 2015 and December 31, 2014 that are accounted for under the fair value option. However, the table below excludes cumulative net fair value adjustments of $392 million and $405 million on these commitments, which are classified in accrued expenses and other liabilities. For more information regarding the Corporation's loan commitments accounted for under the fair value option, see Note 15 – Fair Value Option .

Amounts include consumer SBLCs of $399 million and $396 million at June 30, 2015 and December 31, 2014 . (2) Includes business card unused lines of credit. Legally binding commitments to extend credit generally have specified rates and maturities. Certain of these commitments have adverse change clauses that help to protect the Corporation against deterioration in the borrower's ability to pay. Other Commitments At June 30, 2015 and December 31, 2014 , the Corporation had commitments to purchase loans (e.g., residential mortgage and commercial real estate) of $1.5 billion and $1.8 billion , which upon settlement will be included in loans or LHFS. At June 30, 2015 and December 31, 2014 , the Corporation had commitments to purchase commodities, primarily liquefied natural gas of $3.0 billion and $241 million , which upon settlement will be included in trading account assets. At June 30, 2015 and December 31, 2014 , the Corporation had commitments to enter into forward-dated resale and securities borrowing agreements of $95.0 billion and $73.2 billion , and commitments to enter into forward-dated repurchase and securities lending agreements of $81.0 billion and $55.8 billion . These commitments expire within the next 12 months. The Corporation is a party to operating leases for certain of its premises and equipment. Commitments under these leases are approximately $1.3 billion , $2.4 billion , $2.0 billion , $1.6 billion and $1.3 billion for the remainder of 2015 and the years through 2019 , respectively, and $5.3 billion in the aggregate for all years thereafter . Other Guarantees Bank-owned Life Insurance Book Value Protection The Corporation sells products that offer book value protection to insurance carriers who offer group life insurance policies to corporations, primarily banks. The book value protection is provided on portfolios of intermediate investment-grade fixed-income securities and is intended to cover any shortfall in the event that policyholders surrender their policies and market value is below book value. These guarantees are recorded as derivatives and carried at fair value in the trading portfolio. At June 30, 2015 and December 31, 2014 , the notional amount of these guarantees totaled $13.7 billion and $13.6 billion . At both June 30, 2015 and December 31, 2014 the Corporation's maximum exposure related to these guarantees totaled $3.1 billion with estimated maturity dates between 2031 and 2039. The net fair value including the fee receivable associated with these guarantees was $16 million and $25 million at June 30, 2015 and December 31, 2014 , and reflects the probability of surrender as well as the multiple structural protection features in the contracts. Merchant Services In accordance with credit and debit card association rules, the Corporation sponsors merchant processing servicers that process credit and debit card transactions on behalf of various merchants. In connection with these services, a liability may arise in the event of a billing dispute between the merchant and a cardholder that is ultimately resolved in the cardholder's favor. If the merchant defaults on its obligation to reimburse the cardholder, the cardholder, through its issuing bank, generally has until six months after the date of the transaction to present a chargeback to the merchant processor, which is primarily liable for any losses on covered transactions. However, if the merchant processor fails to meet its obligation to reimburse the cardholder for disputed transactions, then the Corporation, as the sponsor, could be held liable for the disputed amount. For the three and six months ended June 30, 2015 , the sponsored entities processed and settled $171.0 billion and $325.6 billion of transactions and recorded losses of $6 million and $10 million . For the three and six months ended June 30, 2014 , the sponsored entities processed and settled $164.3 billion and $313.7 billion of transactions and recorded losses of $4 million and $8 million . A significant portion of this activity was processed by a joint venture in which the Corporation holds a 49 percent ownership. At June 30, 2015 and December 31, 2014 , the sponsored merchant processing servicers held as collateral $164 million and $130 million of merchant escrow deposits which may be used to offset amounts due from the individual merchants. The Corporation believes the maximum potential exposure for chargebacks would not exceed the total amount of merchant transactions processed through Visa and MasterCard for the last six months, which represents the claim period for the cardholder, plus any outstanding delayed-delivery transactions. As of June 30, 2015 and December 31, 2014 , the maximum potential exposure for sponsored transactions totaled $262.4 billion and $269.3 billion . However, the Corporation believes that the maximum potential exposure is not representative of the actual potential loss exposure and does not expect to make material payments in connection with these guarantees. Other Derivative Contracts The Corporation funds selected assets, including securities issued by CDOs and CLOs, through derivative contracts, typically total return swaps, with third parties and VIEs that are not consolidated by the Corporation. The total notional amount of these derivative contracts was $464 million and $527 million with commercial banks at June 30, 2015 and December 31, 2014 , and $998 million and $1.2 billion with VIEs at June 30, 2015 and December 31, 2014 . The underlying securities are senior securities and substantially all of the Corporation's exposures are insured. Accordingly, the Corporation's exposure to loss consists principally of counterparty risk to the insurers. In certain circumstances, generally as a result of ratings downgrades, the Corporation may be required to purchase the underlying assets, which would not result in additional gain or loss to the Corporation as such exposure is already reflected in the fair value of the derivative contracts. Other Guarantees The Corporation has entered into additional guarantee agreements and commitments, including sold risk participation swaps, liquidity facilities, lease-end obligation agreements, partial credit guarantees on certain leases, real estate joint venture guarantees, divested business commitments and sold put options that require gross settlement. The maximum potential future payment under these agreements was approximately $6.1 billion and $6.2 billion at June 30, 2015 and December 31, 2014 . The estimated maturity dates of these obligations extend up to 2040. The Corporation has made no material payments under these guarantees. In the normal course of business, the Corporation periodically guarantees the obligations of its affiliates in a variety of transactions including ISDA-related transactions and non-ISDA related transactions such as commodities trading, repurchase agreements, prime brokerage agreements and other transactions. Payment Protection Insurance Claims Matter In the U.K., the Corporation previously sold payment protection insurance (PPI) through its international card services business to credit card customers and consumer loan customers. PPI covers a consumer's loan or debt repayment if certain events occur such as loss of job or illness. In response to an elevated level of customer complaints across the industry, heightened media coverage and pressure from consumer advocacy groups, the U.K. Financial Services Authority, which has subsequently been replaced by the Prudential Regulation Authority (PRA) and the Financial Conduct Authority (FCA), investigated and raised concerns about the way some companies have handled complaints related to the sale of these insurance policies. In connection with this matter, the Corporation established a reserve for PPI. The reserve was $205 million and $378 million at June 30, 2015 and December 31, 2014 . The Corporation recorded expense of $16 million for the three and six months ended June 30, 2015 compared to $43 million and $184 million for the same periods in 2014 . It is reasonably possible that the Corporation will incur additional expense related to PPI claims; however, the amount of such additional expense cannot be reasonably estimated. Litigation and Regulatory Matters The following supplements the disclosure in Note 12 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K and in Note 10 – Commitments and Contingencies to the Consolidated Financial Statements of the Corporation's Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2015 (the prior commitments and contingencies disclosure). In the ordinary course of business, the Corporation and its subsidiaries are routinely defendants in or parties to many pending and threatened legal actions and proceedings, including actions brought on behalf of various classes of claimants. These actions and proceedings are generally based on alleged violations of consumer protection, securities, environmental, banking, employment, contract and other laws. In some of these actions and proceedings, claims for substantial monetary damages are asserted against the Corporation and its subsidiaries. In the ordinary course of business, the Corporation and its subsidiaries are also subject to regulatory and governmental examinations, information gathering requests, inquiries, investigations, and threatened legal actions and proceedings. For example, certain subsidiaries of the Corporation are registered broker-dealers or investment advisors and are subject to regulation by the SEC, the Financial Industry Regulatory Authority, the European Commission, the PRA, the FCA and other international, federal and state securities regulators. In connection with formal and informal inquiries, the Corporation and its subsidiaries receive numerous requests, subpoenas and orders for documents, testimony and information in connection with various aspects of the Corporation's regulated activities. In view of the inherent difficulty of predicting the outcome of such litigation, regulatory and governmental matters, particularly where the claimants seek very large or indeterminate damages or where the matters present novel legal theories or involve a large number of parties, the Corporation generally cannot predict what the eventual outcome of the pending matters will be, what the timing of the ultimate resolution of these matters will be, or what the eventual loss, fines or penalties related to each pending matter may be. In accordance with applicable accounting guidance, the Corporation establishes an accrued liability for litigation, regulatory and governmental matters when those matters present loss contingencies that are both probable and estimable. In such cases, there may be an exposure to loss in excess of any amounts accrued. As a litigation, regulatory or governmental matter develops, the Corporation, in conjunction with any outside counsel handling the matter, evaluates on an ongoing basis whether such matter presents a loss contingency that is probable and estimable. When a loss contingency is not both probable and estimable, the Corporation does not establish an accrued liability. If, at the time of evaluation, the loss contingency related to a litigation, regulatory or governmental matter is not both probable and estimable, the matter will continue to be monitored for further developments that would make such loss contingency both probable and estimable. Once the loss contingency related to a litigation, regulatory or governmental matter is deemed to be both probable and estimable, the Corporation will establish an accrued liability with respect to such loss contingency and record a corresponding amount of litigation-related expense. The Corporation continues to monitor the matter for further developments that could affect the amount of the accrued liability that has been previously established. Excluding expenses of internal and external legal service providers, litigation-related expense of $175 million and $545 million was recognized for the three and six months ended June 30, 2015 compared to $4.0 billion and $10.0 billion for the same periods in 2014 . For a limited number of the matters disclosed in this Note, and in the prior commitments and contingencies disclosure, for which a loss, whether in excess of a related accrued liability or where there is no accrued liability, is reasonably possible in future periods, the Corporation is able to estimate a range of possible loss. In determining whether it is possible to estimate a range of possible loss, the Corporation reviews and evaluates its material litigation, regulatory and governmental matters on an ongoing basis, in conjunction with any outside counsel handling the matter, in light of potentially relevant factual and legal developments. These may include information learned through the discovery process, rulings on dispositive motions, settlement discussions, and other rulings by courts, arbitrators or others. In cases in which the Corporation possesses sufficient appropriate information to estimate a range of possible loss, that estimate is aggregated and disclosed below. There may be other disclosed matters for which a loss is probable or reasonably possible but such an estimate of the range of possible loss may not be possible. For those matters where an estimate of the range of possible loss is possible, management currently estimates the aggregate range of possible loss is $0 to $2.3 billion in excess of the accrued liability (if any) related to those matters. This estimated range of possible loss is based upon currently available information and is subject to significant judgment and a variety of assumptions, and known and unknown uncertainties. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from the current estimate. Those matters for which an estimate is not possible are not included within this estimated range. Therefore, this estimated range of possible loss represents what the Corporation believes to be an estimate of possible loss only for certain matters meeting these criteria. It does not represent the Corporation's maximum loss exposure. Information is provided below, or in the prior commitments and contingencies disclosure, regarding the nature of all of these contingencies and, where specified, the amount of the claim associated with these loss contingencies. Based on current knowledge, management does not believe that loss contingencies arising from pending matters, including the matters described herein and in the prior commitments and contingencies disclosure, will have a material adverse effect on the consolidated financial position or liquidity of the Corporation. However, in light of the inherent uncertainties involved in these matters, some of which are beyond the Corporation's control, and the very large or indeterminate damages sought in some of these matters, an adverse outcome in one or more of these matters could be material to the Corporation's results of operations or cash flows for any particular reporting period. Bond Insurance Litigation Ambac Countrywide Litigation On July 2, 2015, the court in the Wisconsin action issued an order dismissing the complaint for lack of personal jurisdiction. Ambac appealed the Wisconsin court order on July 21, 2015. Also on July 21, 2015, Ambac filed a complaint in New York Supreme Court, New York County, regarding the same claims asserted in the Wisconsin complaint. Interchange and Related Litigation On May 19, 2015, one of the two opt-out suits naming the Corporation as a defendant was settled for an amount not material to the Corporation's results of operations. LIBOR, Other Reference Rate and Foreign Exchange (FX) Inquiries and Litigation On May 20, 2015, the Corporation agreed to pay $205 million in civil penalties and to undertake various remedial measures pursuant to a consent order with the Board of Governors of the Federal Reserve System regarding the Corporation’s FX business and related systems and controls. Montgomery Following the district court's dismissal of plaintiffs' complaint and subsequent denial of plaintiffs' motion to amend, on June 15, 2015, the U.S. Court of Appeals for the Second Circuit affirmed the district court’s denial of plaintiffs' motion to amend. On June 29, 2015, plaintiffs filed a petition for rehearing en banc. Mortgage Repurchase Litigation U.S. Bank Summonses with Notice The Trustee has served complaints on four of the seven Trusts. Defendants have until January 8, 2016 to demand complaints relating to the final three Trusts.

Equity [Abstract]
Shareholders' Equity	NOTE 11 – Shareholders' Equity Common Stock The table below presents the declared quarterly cash dividends on common stock in 2015 and through July 29, 2015 . Declaration Date Record Date Payment Date Dividend Per Share July 23, 2015 September 4, 2015 September 25, 2015 $0.05 April 16, 2015 June 5, 2015 June 26, 2015 0.05 February 10, 2015 March 6, 2015 March 27, 2015 0.05 On March 11, 2015, the Corporation announced that the Federal Reserve completed its 2015 Comprehensive Capital Analysis and Review (CCAR) and advised that it did not object to the 2015 capital plan but gave a conditional, non-objection under which the Corporation is required to resubmit its capital plan by September 30, 2015 and address certain weaknesses identified in the capital planning process. The requested capital actions include a request to repurchase $4.0 billion of common stock over five quarters that began in the second quarter of 2015, and to maintain the quarterly common stock dividend at the current rate of $0.05 per share. During the three months ended June 30, 2015 , the Corporation repurchased and retired 48.7 million shares of common stock in connection with the 2015 capital plan, which reduced shareholders' equity by $775 million . During the six months ended June 30, 2015 , in connection with employee stock plans, the Corporation issued approximately 7 million shares and repurchased approximately 3 million shares of its common stock to satisfy tax withholding obligations. At June 30, 2015 , the Corporation had reserved 1.8 billion unissued shares of common stock for future issuances under employee stock plans, common stock warrants, convertible notes and preferred stock. The Corporation has certain warrants outstanding and exercisable to purchase 150.4 million shares of its common stock, expiring on January 16, 2019 and warrants outstanding and exercisable to purchase 121.8 million shares of its common stock, expiring on October 28, 2018. These warrants were originally issued in connection with preferred stock issuances to the U.S. Department of the Treasury in 2009 and 2008, and are listed on the New York Stock Exchange. The exercise price of the warrants expiring on January 16, 2019 is subject to continued adjustment each time the quarterly cash dividend is in excess of $0.01 per common share to compensate the holders of the warrants for dilution resulting from an increased dividend. As a result of the Corporation's second-quarter 2015 dividend of $0.05 per common share, the exercise price of these warrants was adjusted to $13.171 . The warrants expiring on October 28, 2018 also contain this anti-dilution provision except the adjustment is triggered only when the Corporation declares quarterly dividends at a level greater than $0.32 per common share. Preferred Stock During the three months ended March 31, 2015 and June 30, 2015 , the Corporation declared $382 million and $330 million of cash dividends on preferred stock, or a total of $712 million for the six months ended June 30, 2015 . Restricted Stock Units During the six months ended June 30, 2015 , the Corporation granted 131 million restricted stock unit (RSU) awards to certain employees under the Bank of America Corporation 2003 Key Associate Stock Plan (KASP). On May 6, 2015, Bank of America shareholders approved the amendment and restatement of KASP, and renamed it the Bank of America Corporation Key Employee Equity Plan. Generally, one-third of the RSUs vest on each of the first three anniversaries of the grant date provided that the employee remains continuously employed with the Corporation during that time. Except for two million RSUs that are authorized to settle in shares of common stock of the Corporation, the RSUs will be paid in cash to the employees on the vesting date based on the fair value of the Corporation's common stock as of the vesting date. The RSUs are expensed ratably over the vesting period, net of estimated forfeitures, for non-retirement eligible employees based upon the fair value of the Corporation's common stock on the accrual date. For RSUs granted to employees who are retirement eligible or will become retirement eligible during the vesting period, the RSUs are expensed as of the grant date or ratably over the period from the grant date to the date the employee becomes retirement eligible, net of estimated forfeitures. The accrued liability for the RSUs is adjusted to fair value based on changes in the fair value of the Corporation's common stock. The Corporation enters into cash-settled equity derivatives for a significant portion of the RSUs to minimize the change in expense driven by fluctuations in the fair value of the RSUs over the applicable vesting period. For additional information, see Note 18 – Stock-based Compensation Plans to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K .

Earnings Per Common Share	NOTE 13 – Earnings Per Common Share The calculation of earnings per common share (EPS) and diluted EPS for both the three and six months ended June 30, 2015 and 2014 is presented below. For more information on the calculation of EPS, see Note 1 – Summary of Significant Accounting Principles to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K .

The Corporation previously issued a warrant to purchase 700 million shares of the Corporation's common stock to the holder of the Series T Preferred Stock. The warrant may be exercised, at the option of the holder, through tendering the Series T Preferred Stock or paying cash. For the three and six months ended June 30, 2015 , the 700 million average dilutive potential common shares were included in the diluted share count under the "if-converted" method. For the three months ended June 30, 2014 , the 700 million average dilutive potential common shares were included in the diluted share count under the "if-converted" method. For the six months ended June 30, 2014 , the 700 million average dilutive potential common shares were not included in the diluted share count because the result would have been antidilutive under the "if-converted" method. For both the three and six months ended June 30, 2015 and 2014 , 62 million average dilutive potential common shares associated with the 7.25% Non-Cumulative Perpetual Convertible Preferred Stock, Series L were not included in the diluted share count because the result would have been antidilutive under the "if-converted" method. For the three and six months ended June 30, 2015 , average options to purchase 64 million and 68 million shares of common stock were outstanding but not included in the computation of EPS because the result would have been antidilutive under the treasury stock method compared to 89 million and 95 million for the same periods in 2014 . For both the three and six months ended June 30, 2015 and 2014 , average warrants to purchase 122 million shares of common stock were outstanding but not included in the computation of EPS because the result would have been antidilutive under the treasury stock method and average warrants to purchase 150 million shares of common stock were included in the diluted EPS calculation using the treasury stock method.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 14 – Fair Value Measurements Under applicable accounting guidance, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Corporation determines the fair values of its financial instruments based on the fair value hierarchy established under applicable accounting guidance which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs used to measure fair value. The Corporation conducts a review of its fair value hierarchy classifications on a quarterly basis. Transfers into or out of fair value hierarchy classifications are made if the significant inputs used in the financial models measuring the fair values of the assets and liabilities became unobservable or observable, respectively, in the current marketplace. These transfers are considered to be effective as of the beginning of the quarter in which they occur. For more information regarding the fair value hierarchy and how the Corporation measures fair value, see Note 1 – Summary of Significant Accounting Principles and Note 20 – Fair Value Measurements to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . The Corporation accounts for certain financial instruments under the fair value option. For additional information, see Note 15 – Fair Value Option . Valuation Processes and Techniques The Corporation has various processes and controls in place to ensure that fair value is reasonably estimated. A model validation policy governs the use and control of valuation models used to estimate fair value. This policy requires review and approval of models by personnel who are independent of the front office, and periodic reassessments of models to ensure that they are continuing to perform as designed. In addition, detailed reviews of trading gains and losses are conducted on a daily basis by personnel who are independent of the front office. A price verification group, which is also independent of the front office, utilizes available market information including executed trades, market prices and market-observable valuation model inputs to ensure that fair values are reasonably estimated. The Corporation performs due diligence procedures over third-party pricing service providers in order to support their use in the valuation process. Where market information is not available to support internal valuations, independent reviews of the valuations are performed and any material exposures are escalated through a management review process. While the Corporation believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. During the six months ended June 30, 2015 , there were no changes to the valuation techniques that had, or are expected to have, a material impact on the Corporation's consolidated financial position or results of operations. Level 1, 2 and 3 Valuation Techniques Financial instruments are considered Level 1 when the valuation is based on quoted prices in active markets for identical assets or liabilities. Level 2 financial instruments are valued using quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or models using inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Financial instruments are considered Level 3 when their values are determined using pricing models, discounted cash flow methodologies or similar techniques, and at least one significant model assumption or input is unobservable and when determination of the fair value requires significant management judgment or estimation. Recurring Fair Value Assets and liabilities carried at fair value on a recurring basis at June 30, 2015 and December 31, 2014 , including financial instruments which the Corporation accounts for under the fair value option, are summarized in the following tables.

(6) Other assets is primarily comprised of certain long-term fixed-rate margin loans and private equity investments that are accounted for under the fair value option. During the three months ended June 30, 2015 , the transfers into Level 3 included $835 million of trading account assets, $112 million of loans and leases, $326 million of federal funds purchased and securities loaned or sold under agreements to repurchase and $403 million of long-term debt. Transfers into Level 3 for trading account assets were primarily the result of decreased availability of third-party prices for certain corporate debt securities. Transfers into Level 3 for loans and leases were primarily due to decreased price observability. Transfers into Level 3 for federal funds purchased and securities loaned or sold under agreements to repurchase were due to decreased price availability for certain structured secured financing agreements. Transfers into Level 3 for long-term debt were primarily due to changes in the impact of unobservable inputs on the value of certain structured liabilities. Transfers occur on a regular basis for these long-term debt instruments due to changes in the impact of unobservable inputs on the value of the embedded derivative in relation to the instrument as a whole. During the three months ended June 30, 2015 , the transfers out of Level 3 included $110 million of trading account assets and $368 million of long-term debt. Transfers out of Level 3 for trading account assets were primarily the result of increased market liquidity and price observability for certain corporate debt securities. Transfers out of Level 3 for long-term debt were primarily due to changes in the impact of unobservable inputs on the value of certain structured liabilities.

During the three months ended June 30, 2014 , the transfers into Level 3 included $258 million of trading account assets and $676 million of long-term debt. Transfers into Level 3 for trading account assets were primarily the result of decreased availability of third-party prices for certain corporate loans and securities. Transfers into Level 3 for long-term debt were primarily due to changes in the impact of unobservable inputs on the value of certain structured liabilities. Transfers occur on a regular basis for these long-term debt instruments due to changes in the impact of unobservable inputs on the value of the embedded derivative in relation to the instrument as a whole. During the three months ended June 30, 2014 , the transfers out of Level 3 included $224 million of trading account assets and $274 million of net derivative assets. Transfers out of Level 3 for trading account assets were primarily the result of increased market liquidity and availability of third-party prices for certain corporate loans and securities. Transfers out of Level 3 for net derivative assets were primarily due to increased price observability for certain equity derivatives.

During the six months ended June 30, 2015 , the transfers into Level 3 included $1.0 billion of trading account assets, $132 million of AFS debt securities, $118 million of loans and leases, $177 million of LHFS, $326 million of federal funds purchased and securities loaned or sold under agreements to repurchase and $1.1 billion of long-term debt. Transfers into Level 3 for trading account assets were primarily the result of decreased availability of third-party prices for certain corporate debt securities. Transfers into Level 3 for AFS debt securities were primarily due to decreased price observability on certain CLOs. Transfers into Level 3 for loans and leases were primarily due to decreased price observability. Transfers into Level 3 for LHFS were primarily due to decreased price observability due to a decline in trading activity. Transfers into Level 3 for federal funds purchased and securities loaned or sold under agreements to repurchase were due to decreased price availability for certain structured secured financing agreements. Transfers into Level 3 for long-term debt were primarily due to changes in the impact of unobservable inputs on the value of certain structured liabilities. Transfers occur on a regular basis for these long-term debt instruments due to changes in the impact of unobservable inputs on the value of the embedded derivative in relation to the instrument as a whole. During the six months ended June 30, 2015 , the transfers out of Level 3 included $410 million of trading account assets, $122 million of net derivative assets, $933 million of AFS debt securities and $494 million of long-term debt. Transfers out of Level 3 for trading account assets were primarily the result of increased market liquidity and price observability for certain corporate debt securities. Transfers out of Level 3 for net derivative assets were primarily due to increased price observability related to certain equity derivatives. Transfers out of Level 3 for AFS debt securities were primarily due to increased price observability for certain corporate debt securities. Transfers out of Level 3 for long-term debt were primarily due to changes in the impact of unobservable inputs on the value of certain structured liabilities.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	NOTE 16 – Fair Value of Financial Instruments Financial instruments are classified within the fair value hierarchy using the methodologies described in Note 14 – Fair Value Measurements . The following disclosures include financial instruments where only a portion of the ending balance at June 30, 2015 and December 31, 2014 was carried at fair value on the Consolidated Balance Sheet. For more information on these financial instruments and their valuation methodologies, see Note 20 – Fair Value Measurements and Note 22 – Fair Value of Financial Instruments to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . Fair Value of Financial Instruments The carrying values and fair values by fair value hierarchy of certain financial instruments where only a portion of the ending balance was carried at fair value at June 30, 2015 and December 31, 2014 are presented in the table below.

The Corporation accounts for certain loan commitments under the fair value option. The carrying values and fair values of the Corporation's commercial unfunded lending commitments were $981 million and $4.1 billion at June 30, 2015 , and $932 million and $3.8 billion at December 31, 2014 . Commercial unfunded lending commitments are primarily classified as Level 3. The carrying value of these commitments is classified in accrued expenses and other liabilities. The Corporation does not estimate the fair values of consumer unfunded lending commitments because, in many instances, the Corporation can reduce or cancel these commitments by providing notice to the borrower. For more information on commitments, see Note 10 – Commitments and Contingencies .

Transfers and Servicing [Abstract]
Mortgage Servicing Rights	NOTE 17 – Mortgage Servicing Rights The Corporation accounts for consumer MSRs at fair value with changes in fair value recorded in mortgage banking income in the Consolidated Statement of Income. The Corporation manages the risk in these MSRs with derivatives such as options and interest rate swaps, which are not designated as accounting hedges, as well as securities including MBS and U.S. Treasury securities. The securities used to manage the risk in the MSRs are classified in other assets with changes in the fair value of the securities and the related interest income recorded in mortgage banking income. The table below presents activity for residential mortgage and home equity MSRs for the three and six months ended June 30, 2015 and 2014 . Rollforward of Mortgage Servicing Rights Three Months Ended Six Months Ended (Dollars in millions) 2015 2014 2015 2014 Balance, beginning of period $ 3,394 $ 4,765 $ 3,530 $ 5,042 Additions 204 113 383 378 Sales (312 ) (26 ) (312 ) (46 ) Amortization of expected cash flows (1) (223 ) (235 ) (453 ) (467 ) Impact of changes in interest rates and other market factors (2) 468 (310 ) 292 (627 ) Model and other cash flow assumption changes: (3) Projected cash flows, including changes in costs to service loans (1 ) 82 86 46 Impact of changes in the Home Price Index 2 4 (10 ) (7 ) Impact of changes to the prepayment model — — 9 160 Other model changes (4) (11 ) (25 ) (4 ) (111 ) Balance, June 30 (5) $ 3,521 $ 4,368 $ 3,521 $ 4,368 Mortgage loans serviced for investors (in billions) $ 425 $ 521 $ 425 $ 521 (1) Represents the net change in fair value of the MSR asset due to the recognition of modeled cash flows. (2) These amounts reflect the changes in modeled MSR fair value primarily due to observed changes in interest rates, volatility, spreads and the shape of the forward swap curve and periodic adjustments to valuation based on third-party price discovery. (3) These amounts reflect periodic adjustments to the valuation model to reflect changes in the modeled relationship between inputs and their impact on projected cash flows as well as changes in certain cash flow assumptions such as cost to service and ancillary income per loan. (4) These amounts include the impact of periodic recalibrations of the model to reflect changes in the relationship between market interest rate spreads and projected cash flows. (5) At June 30, 2015 , includes $3.2 billion of U.S. and $320 million of non-U.S. consumer MSR balances compared to $4.1 billion and $234 million at June 30, 2014 . The Corporation primarily uses an option-adjusted spread (OAS) valuation approach which factors in prepayment risk 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. In addition to updating the valuation model for interest, discount and prepayment rates, periodic adjustments are made to recalibrate the valuation model for factors used to project cash flows. The changes to the factors capture the effect of variances related to actual versus estimated servicing proceeds. Significant economic assumptions in estimating the fair value of MSRs at June 30, 2015 and December 31, 2014 are presented below. The change in fair value as a result of changes in OAS rates is included within "Model and other cash flow assumption changes" in the Rollforward of Mortgage Servicing Rights table. The weighted-average life is not an input in the valuation model but is a product of both changes in market rates of interest and changes in model and other cash flow assumptions. The weighted-average life represents the average period of time that the MSRs' cash flows are expected to be received. Absent other changes, an increase (decrease) to the weighted-average life would generally result in an increase (decrease) in the fair value of the MSRs. Significant Economic Assumptions June 30, 2015 December 31, 2014 Fixed Adjustable Fixed Adjustable Weighted-average OAS 4.56 % 7.67 % 4.52 % 7.61 % Weighted-average life, in years 4.89 3.36 4.53 2.95 The table below presents the sensitivity of the weighted-average lives and fair value of MSRs to changes in modeled assumptions. These sensitivities are hypothetical and should be used with caution. As the amounts indicate, changes in fair value based on variations in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of MSRs that continue to be held by the Corporation is calculated without changing any other assumption. In reality, changes in one factor may result in changes in another, which might magnify or counteract the sensitivities. The below sensitivities do not reflect any hedge strategies that may be undertaken to mitigate such risk. Sensitivity Impacts June 30, 2015 Change in Weighted-average Lives (Dollars in millions) Fixed Adjustable Change in Fair Value Prepayment rates Impact of 10% decrease 0.23 years 0.20 years $ 200 Impact of 20% decrease 0.49 0.43 424 Impact of 10% increase (0.21 ) (0.18 ) (181 ) Impact of 20% increase (0.39 ) (0.33 ) (344 ) OAS level Impact of 100 bps decrease $ 156 Impact of 200 bps decrease 327 Impact of 100 bps increase (144 ) Impact of 200 bps increase (278 )

Business Segment Information	NOTE 18 – Business Segment Information Effective January 1, 2015, to align the segments with how the Corporation manages the businesses in 2015, it changed its basis of presentation, and following such change, reports its results of operations through the following five business segments: Consumer Banking , Global Wealth & Investment Management (GWIM) , Global Banking , Global Markets and Legacy Assets & Servicing (LAS) , with the remaining operations recorded in All Other . The Home Loans business, which was included in the former Consumer Real Estate Services ( CRES) segment, is now included in Consumer Banking , and LAS (also in the former CRES segment) became a separate segment. A portion of the Business Banking business, based on the size of the client, was moved from the former Consumer & Business Banking (CBB) segment to Global Banking , and the former CBB segment was renamed Consumer Banking . Also, the merchant services joint venture moved from the former CBB segment to All Other . In addition, certain management accounting methodologies, including the treatment of intersegment assets and liabilities, and related allocations were refined. Prior periods have been reclassified to conform to the current period presentation. Consumer Banking Consumer Banking offers a diversified range of credit, banking and investment products and services to consumers and small businesses. Consumer Banking product offerings include traditional savings accounts, money market savings accounts, CDs and IRAs, noninterest- and interest-bearing checking accounts, investment accounts and products , as well as credit and debit cards, residential mortgages and home equity loans, and direct and indirect loans to consumers and small businesses in the U.S. Customers and clients have access to a franchise network that stretches coast to coast through 33 states and the District of Columbia. The franchise network includes approximately 4,800 financial centers, 16,000 ATMs, nationwide call centers, and online and mobile platforms. Global Wealth & Investment Management GWIM provides a high-touch client experience through a network of financial advisors focused on clients with over $250,000 in total investable assets , as well as tailored solutions to meet clients' needs through a full set of brokerage, banking and retirement products. GWIM also provides comprehensive wealth management solutions targeted to high net worth and ultra high net worth clients, as well as customized solutions to meet clients' wealth structuring, investment management, trust and banking needs, including specialty asset management services. Global Banking Global Banking provides a wide range of lending-related products and services, integrated working capital management and treasury solutions to clients, and underwriting and advisory services through the Corporation's network of offices and client relationship teams. Global Banking's lending products and services include commercial loans, leases, commitment facilities, trade finance, real estate lending and asset-based lending. Global Banking's treasury solutions business includes treasury management, foreign exchange and short-term investing options. Global Banking also provides investment banking products to clients such as debt and equity underwriting and distribution, and merger-related and other advisory services. The economics of most investment banking and underwriting activities are shared primarily between Global Banking and Global Markets based on the activities performed by each segment . Global Banking clients generally include middle-market companies, commercial real estate firms, auto dealerships , not-for-profit companies , large global corporations, financial institutions , leasing clients , and mid-sized U.S.-based businesses requiring customized and integrated financial advice and solutions . Global Markets Global Markets offers sales and trading services, including research, to institutional clients across fixed-income, credit, currency, commodity and equity businesses. Global Markets product coverage includes securities and derivative products in both the primary and secondary markets. Global Markets provides market-making, financing, securities clearing, settlement and custody services globally to institutional investor clients in support of their investing and trading activities. Global Markets also works with commercial and corporate clients to provide risk management products using interest rate, equity, credit, currency and commodity derivatives, foreign exchange, fixed-income and mortgage-related products. As a result of market-making activities in these products, Global Markets may be required to manage risk in a broad range of financial products including government securities, equity and equity-linked securities, high-grade and high-yield corporate debt securities, syndicated loans, MBS, commodities and ABS. In addition, the economics of most investment banking and underwriting activities are shared primarily between Global Markets and Global Banking based on the activities performed by each segment . Legacy Assets & Servicing LAS is responsible for mortgage servicing activities related to residential first mortgage and home equity loans serviced for others and loans held by the Corporation, including loans that have been designated as the LAS Portfolios, and manages certain legacy exposures related to mortgage origination, sales and servicing activities (e.g., litigation, representations and warranties). LAS also includes the results of MSR activities, including net hedge results . Home equity loans are held on the balance sheet of LAS , and residential mortgage loans are included as part of All Other . The financial results of the on-balance sheet loans are reported in the segment that owns the loans or in All Other . All Other All Other consists of ALM activities, equity investments, the international consumer card business, liquidating businesses, residual expense allocations and other. ALM activities encompass residential mortgages, MBS, interest rate and foreign currency risk management activities including the residual net interest income allocation, the impact of certain allocation methodologies and accounting hedge ineffectiveness. Additionally, certain residential mortgage loans that are managed by LAS are held in All Other . The results of certain ALM activities are allocated to the business segments . Basis of Presentation The management accounting and reporting process derives segment and business results by utilizing allocation methodologies for revenue and expense. The net income derived for the businesses is dependent upon revenue and cost allocations using an activity-based costing model, funds transfer pricing, and other methodologies and assumptions management believes are appropriate to reflect the results of the business. Total revenue, net of interest expense, includes net interest income on an FTE basis and noninterest income. The adjustment of net interest income to an FTE basis results in a corresponding increase in income tax expense. The segment results also reflect certain revenue and expense methodologies that are utilized to determine net income. The net interest income of the businesses includes the results of a funds transfer pricing process that matches assets and liabilities with similar interest rate sensitivity and maturity characteristics. In segments where the total of liabilities and equity exceeds assets, which are generally deposit-taking segments, the Corporation allocates assets to match liabilities. Net interest income of the business segments also includes an allocation of net interest income generated by certain of the Corporation's ALM activities. Further, net interest income on an FTE basis includes market-related adjustments, which are driven by the impact of changes in long-term interest rates on the estimated lives of mortgage-related debt securities thereby impacting premium amortization. Also included in market-related adjustments is hedge ineffectiveness that impacted net interest income. In addition, the business segments are impacted by the migration of customers and clients and their deposit, loan and brokerage balances between client-managed businesses. Subsequent to the date of migration, the associated net interest income, noninterest income and noninterest expense are recorded in the business to which the customers or clients migrated. The Corporation's ALM activities include an overall interest rate risk management strategy that incorporates the use of various derivatives and cash instruments to manage fluctuations in earnings and capital that are caused by interest rate volatility. The Corporation's goal is to manage interest rate sensitivity so that movements in interest rates do not significantly adversely affect earnings and capital. The results of a majority of the Corporation's ALM activities are allocated to the business segments and fluctuate based on the performance of the ALM activities. ALM activities include external product pricing decisions including deposit pricing strategies, the effects of the Corporation's internal funds transfer pricing process and the net effects of other ALM activities. Certain expenses not directly attributable to a specific business segment are allocated to the segments. The most significant of these expenses include data and item processing costs and certain centralized or shared functions. Data processing costs are allocated to the segments based on equipment usage. Item processing costs are allocated to the segments based on the volume of items processed for each segment. The costs of certain other centralized or shared functions are allocated based on methodologies that reflect utilization. The following tables present net income (loss) and the components thereto (with net interest income on an FTE basis) for the three and six months ended June 30, 2015 and 2014 , and total assets at June 30, 2015 and 2014 for each business segment, as well as All Other .

Accounting Policies [Abstract]
Consolidation	The Consolidated Financial Statements include the accounts of the Corporation and its majority-owned subsidiaries, and those variable interest entities (VIEs) where the Corporation is the primary beneficiary. Intercompany accounts and transactions have been eliminated. Results of operations of acquired companies are included from the dates of acquisition and for VIEs, from the dates that the Corporation became the primary beneficiary. Assets held in an agency or fiduciary capacity are not included in the Consolidated Financial Statements. The Corporation accounts for investments in companies for which it owns a voting interest and for which it has the ability to exercise significant influence over operating and financing decisions using the equity method of accounting. These investments are included in other assets. Equity method investments are subject to impairment testing and the Corporation's proportionate share of income or loss is included in equity investment income.
Basis of Accounting	The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts and disclosures. Realized results could differ from those estimates and assumptions. The Corporation's Annual Report on Form 10-K for the year ended December 31, 2014 as supplemented by a Current Report on Form 8-K filed on April 29, 2015 to reflect reclassified business segment information is referred to herein as the 2014 Annual Report on Form 10-K. These unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K. The nature of the Corporation's business is such that the results of any interim period are not necessarily indicative of results for a full year. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim period results have been made. The Corporation evaluates subsequent events through the date of filing with the Securities and Exchange Commission (SEC). Certain prior-period amounts have been reclassified to conform to current period presentation. In the Consolidated Statement of Cash Flows for the six months ended June 30, 2014 , the Corporation revised certain line item amounts (e.g., purchases and proceeds from sales of debt securities carried at fair value) in the investing activities section to appropriately reflect sweep activity. This had no impact on total cash flows from investing activities.
New Accounting Pronouncements	In February 2015, the Financial Accounting Standards Board (FASB) issued new accounting guidance that amends the criteria for determining whether limited partnerships and similar entities are VIEs, clarifies when a general partner or asset manager should consolidate an entity and eliminates the indefinite deferral of certain aspects of VIE accounting guidance for investments in certain investment funds. Money market funds registered under Rule 2a-7 of the Investment Company Act and similar funds are exempt from consolidation under the new guidance. The new accounting guidance is effective beginning on January 1, 2016. Early adoption is permitted; however, the Corporation does not expect to adopt this new guidance early. The Corporation does not expect the new guidance to have a material impact on its consolidated financial position or results of operations. In June 2014, the FASB issued new guidance on accounting and disclosure of repurchase-to-maturity (RTM) transactions and repurchase financings (repos). Under this new accounting guidance, RTMs are accounted for as secured borrowings rather than sales of an asset, and transfers of financial assets with a contemporaneous repo are no longer evaluated to determine whether they should be accounted for on a combined basis as forward contracts. The new guidance also prescribes additional disclosures particularly on the nature of collateral pledged in repos accounted for as secured borrowings. The new guidance was effective beginning on January 1, 2015 and did not have a material impact on the Corporation's consolidated financial position or results of operations. For the additional disclosures under this guidance, see Note 2 – Derivatives and Note 9 – Federal Funds Sold or Purchased, Securities Financing Agreements and Short-term Borrowings . In May 2014, the FASB issued new accounting guidance to clarify the principles for recognizing revenue from contracts with customers. The new accounting guidance, which does not apply to financial instruments, is effective on a retrospective basis beginning on January 1, 2018. The Corporation is assessing the impact of this new guidance on its consolidated financial position and results of operations.

Derivative [Line Items]
Schedule of Derivative Instruments in Statement of Financial Position, Fair Value	The table below summarizes information related to fair value hedges for the three and six months ended June 30, 2015 and 2014 , including hedges of interest rate risk on long-term debt that were acquired as part of a business combination and redesignated at that time. At redesignation, the fair value of the derivatives was positive. As the derivatives mature, the fair value will approach zero. As a result, ineffectiveness will occur and the fair value changes in the derivatives and the long-term debt being hedged may be directionally the same in certain scenarios. Based on a regression analysis, the derivatives continue to be highly effective at offsetting changes in the fair value of the long-term debt attributable to interest rate risk.

Cash Flow and Net Investment Hedges	The table below summarizes certain information related to cash flow hedges and net investment hedges for the three and six months ended June 30, 2015 and 2014 . Of the $1.4 billion net loss (after-tax) on derivatives in accumulated other comprehensive income (OCI) at June 30, 2015 , $698 million ( $436 million after-tax) is expected to be reclassified into earnings in the next 12 months.

Corporation Recorded Other-than-Temporary Impairment Losses on AFS Debt Securities	The Corporation recorded other-than-temporary impairment (OTTI) losses on AFS debt securities for the three and six months ended June 30, 2015 and 2014 as presented in the Net Credit-related Impairment Losses Recognized in Earnings table. Substantially all OTTI losses in the three and six months ended June 30, 2015 and 2014 consisted of credit losses on non-agency residential mortgage-backed securities (RMBS) and were recorded in other income in the Consolidated Statement of Income. The credit losses on the RMBS during the six months ended June 30, 2015 were driven by decreases in the estimated RMBS cash flows primarily due to a model change resulting in the refinement of the expected cash flows. A debt security is impaired when its fair value is less than its amortized cost. If the Corporation intends or will more-likely-than-not be required to sell a debt security prior to recovery, the entire impairment loss is recorded in the Consolidated Statement of Income. For AFS debt securities the Corporation does not intend or will not more-likely-than-not be required to sell, an analysis is performed to determine if any of the impairment is due to credit or whether it is due to other factors (e.g., interest rate). Credit losses are considered unrecoverable and are recorded in the Consolidated Statement of Income with the remaining unrealized losses recorded in OCI. In certain instances, the credit loss on a debt security may exceed the total impairment, in which case, the excess of the credit loss over the total impairment is recorded as an unrealized gain in OCI.

Accretable Yield Activity	The table below shows activity for the accretable yield on PCI loans, which includes the Countrywide Financial Corporation (Countrywide) portfolio and loans repurchased in connection with the settlement with FNMA. For more information on the settlement with FNMA, see Note 7 – Representations and Warranties Obligations and Corporate Guarantees to the Consolidated Financial Statements of the Corporation's 2014 Annual Report on Form 10-K . The amount of accretable yield is affected by changes in credit outlooks, including metrics such as default rates and loss severities, prepayment speeds, which can change the amount and period of time over which interest payments are expected to be received, and the interest rates on variable rate loans. The reclassifications from nonaccretable difference in the three and six months ended June 30, 2015 were primarily due to a decrease in forecasted prepayment speeds as a result of higher interest rates. Changes in the prepayment assumption affect the expected remaining life of the portfolio which results in a change to the amount of future interest cash flows. Rollforward of Accretable Yield (Dollars in millions) Three Months Ended June 30, 2015 Six Months Ended June 30, 2015 Accretable yield, beginning of period $ 5,167 $ 5,608 Accretion (220 ) (453 ) Disposals/transfers (129 ) (265 ) Reclassifications from nonaccretable difference 150 78 Accretable yield, June 30, 2015 $ 4,968 $ 4,968

(4) These amounts include the impact of periodic recalibrations of the model to reflect changes in the relationship between market interest rate spreads and projected cash flows. (5) At June 30, 2015 , includes $3.2 billion of U.S. and $320 million of non-U.S. consumer MSR balances compared to $4.1 billion and $234 million at June 30, 2014 .

Sensitivity of the Weighted-Average Lives and Fair Value of MSRs	The table below presents the sensitivity of the weighted-average lives and fair value of MSRs to changes in modeled assumptions. These sensitivities are hypothetical and should be used with caution. As the amounts indicate, changes in fair value based on variations in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of MSRs that continue to be held by the Corporation is calculated without changing any other assumption. In reality, changes in one factor may result in changes in another, which might magnify or counteract the sensitivities. The below sensitivities do not reflect any hedge strategies that may be undertaken to mitigate such risk.
