Basis of Presentation
Summary of Significant Accounting and Reporting Policies	1. Basis of Presentation
	The Condensed Consolidated Financial Statements include the accounts of the Bancorp and its majority-owned subsidiaries and VIEs in which the Bancorp has been determined to be the primary beneficiary. Other entities, including certain joint ventures, in which the Bancorp has the ability to exercise significant influence over operating and financial policies of the investee, but upon which the Bancorp does not possess control, are accounted for by the equity method and not consolidated. Those entities in which the Bancorp does not have the ability to exercise significant influence are generally carried at the lower of cost or fair value. Intercompany transactions and balances have been eliminated.
	In the opinion of management, the unaudited Condensed Consolidated Financial Statements include all adjustments, which consist of normal recurring accruals, necessary to present fairly the results for the periods presented. In accordance with U.S. GAAP and the rules and regulations of the SEC for interim financial information, these statements do not include certain information and footnote disclosures required for complete annual financial statements and it is suggested that these Condensed Consolidated Financial Statements be read in conjunction with the Bancorp's Annual Report on Form 10-K. The results of operations and comprehensive income for the three months ended March 31, 2015 and 2014 and the cash flows and changes in equity for the three months ended March 31, 2015 and 2014 are not necessarily indicative of the results to be expected for the full year. Financial information as of December 31, 2014 has been derived from the Bancorp's Annual Report on Form 10-K.
	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Accounting and Reporting Developments
Accounting and Reporting Developments	3. Accounting and Reporting Developments
	Accounting for Investments in Qualified Affordable Housing Projects
	In January 2014, the FASB issued amended guidance which would permit the Bancorp to make an accounting policy election to account for its investments in qualified affordable housing projects using a proportional amortization method if certain conditions are met and to present the amortization as a component of income tax expense. The amended guidance would be applied retrospectively to all periods presented and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014, with early adoption permitted. Regardless of the policy election, the amended guidance requires disclosures to enable the users of the financial statements to understand the nature of the Bancorp's investments in qualified affordable housing projects and the effect of the measurement of the investments in qualified affordable housing projects and the related tax credits on the Bancorp's financial position and results of operation.
	The Bancorp adopted the amended guidance on January 1, 2015, and did not make an accounting policy election to apply the proportional amortization method for its investments in qualified affordable housing projects. Therefore, the adoption of the amended guidance did not have a material impact on the Condensed Consolidated Financial Statements. The required disclosures are included in Note 10.
	Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure
	In January 2014, the FASB issued amended guidance that clarifies when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. The amended guidance clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. In addition, the amended guidance requires interim and annual disclosures of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. The amended guidance may be applied prospectively or through a modified retrospective approach and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014, with early adoption permitted. The Bancorp adopted the amended guidance prospectively on January 1, 2015 and the adoption of the amended guidance did not have a material impact on the Condensed Consolidated Financial Statements. The required disclosures are included in Note 6.
	Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity
	In April 2014, the FASB issued amended guidance that changes the criteria for reporting discontinued operations. The amended guidance requires a disposal of a component of an entity or a group of components of an entity to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results when any of the following occurs: 1) the component of an entity or group of components of an entity meets the criteria to be classified as held for sale; 2) the component of an entity or group of components of an entity is disposed of by sale; or 3) the component of an entity or group of components of an entity is disposed of other than by sale (for example, by abandonment or in a distribution to owners in a spinoff). The amended guidance requires an entity to present, for each comparative period, the assets and liabilities of a disposal group that includes a discontinued operation separately in the asset and liability sections, respectively, of the statement of financial position, as well as additional disclosures about discontinued operations. The amended guidance is to be applied prospectively for 1) all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years; and 2) all businesses or nonprofit activities that, on acquisition, are classified as held for sale that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. The Bancorp adopted the amended guidance on January 1, 2015 and the adoption of the amended guidance did not have a material impact on the Condensed Consolidated Financial Statements.
	Revenue from Contracts with Customers
	In May 2014, the FASB issued amended guidance on revenue recognition from contracts with customers. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most contract revenue recognition guidance, including industry-specific guidance. The core principle of the amended guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amended guidance is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those years, and should be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the amendments recognized at the date of initial application. Early adoption is prohibited. In April 2015, the FASB tentatively decided to extend the adoption date to annual periods beginning after December 15, 2017, and interim periods within those years. The FASB announced they intend to expose this tentative decision for a 30-day comment period under a proposed ASU during the second quarter of 2015. The Bancorp is currently in the process of evaluating the impact of adopting the amended guidance on its Condensed Consolidated Financial Statements.
	Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures
	In June 2014, the FASB issued amended guidance that changes the accounting for repurchase-to-maturity transactions to secured borrowing accounting. The amended guidance also requires separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty, which will result in secured borrowing accounting for the repurchase agreement. The amended guidance requires disclosures for certain transactions comprising: 1) a transfer of a financial asset accounted for as a sale and 2) an agreement with the same transferee entered into in contemplation of the initial transfer that results in the transferor retaining substantially all of the exposure to the economic return on the transferred financial asset throughout the term of the transaction. The amended guidance also requires new disclosures for repurchase agreements, securities lending transactions and repurchase-to-maturity transactions accounted for as secured borrowings. The amended guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014, with early adoption prohibited. Changes in accounting for transactions outstanding on the effective date should be presented as a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The disclosures for certain transactions accounted for as a sale are required to be presented for interim and annual periods beginning after December 15, 2014, and the disclosures for repurchase agreements, securities lending transactions and repurchase-to-maturity transactions accounted for as secured borrowings are required to be presented for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. The Bancorp adopted the amended guidance on January 1, 2015 and the adoption of the amended guidance did not have a material impact on the Condensed Consolidated Financial Statements.
	Accounting for Share-Based Payments When the Terms of the Award Provide That a Performance Target Could be Achieved after the Requisite Service Period
	In June 2014, the FASB issued amended guidance which clarifies that a performance target that affects vesting and can be achieved after the requisite service period be treated as a performance condition. The amended guidance provides that an entity should apply existing guidance as it relates to awards with performance conditions that affect vesting to account for such awards. As such, the performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved. The amended guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015, with early adoption permitted. The amended guidance may be adopted either prospectively to all awards granted or modified after the effective date or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. If retrospective transition is adopted, the cumulative effect of applying the amended guidance as of the beginning of the earliest annual period presented in the financial statements should be recognized as an adjustment to the opening retained earnings balance at that date. The adoption of the amended guidance is not expected to have a material impact on the Condensed Consolidated Financial Statements.
	Measuring the Financial Assets and Financial Liabilities of a Consolidated Collateralized Financing Entity
	In August 2014, the FASB issued amended guidance that provides an alternative to ASC Topic 820: Fair Value Measurement for measuring the financial assets and financial liabilities of a CFE, such as a collateralized debt obligation or a collateralized loan obligation entity consolidated as a VIE when 1) all of the financial assets and the financial liabilities of that CFE are measured at fair value in the consolidated financial statements and 2) the changes in the fair values of those financial assets and financial liabilities are reflected in earnings. If elected, the measurement alternative would allow the Bancorp to measure both the financial assets and the financial liabilities of the CFE by using the more observable of the fair value of the financial assets or the fair value of the financial liabilities and to eliminate any measurement difference. When the measurement alternative is not elected for a consolidated CFE within the scope of this amended guidance, the amendments clarify that 1) the fair value of the financial assets and the fair value of the financial liabilities of the consolidated CFE should be measured using the requirements of Topic 820 and 2) any difference in the fair value of the financial assets and the fair value of the financial liabilities of that consolidated CFE should be reflected in earnings and attributed to the Bancorp in the Condensed Consolidated Statements of Income. The amended guidance may be applied retrospectively or through a modified retrospective approach and is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The adoption of the amended guidance is not expected to have a material impact on the Condensed Consolidated Financial Statements.
	Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure
	In August 2014, the FASB issued amended guidance clarifying the classification of certain foreclosed mortgage loans that are either full or partially guaranteed under government programs. The amended guidance requires that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: 1) the loan has a government guarantee that is not separable from the loan before foreclosure; 2) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and 3) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable would be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The amended guidance may be applied prospectively or through a modified retrospective approach and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014, with early adoption permitted. The Bancorp adopted the amended guidance prospectively on January 1, 2015 and the adoption of the amended guidance did not have a material impact on the Condensed Consolidated Financial Statements. The disclosures of the Bancorp's foreclosed mortgage loans that are either fully or partially guaranteed under government programs are included in Note 6.
	Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or Equity
	In November 2014, the FASB issued amended guidance that clarifies how current GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features—including the embedded derivative features being evaluated for bifurcation—in evaluating the nature of the host contract. Furthermore, the amendments clarify that no single term or feature would necessarily determine the economic characteristics and risks of the host contract. Rather, the nature of the host contract depends upon the economic characteristics and risks of the entire hybrid financial instrument. The amended guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The effects of initially adopting the amended guidance should be applied on a modified retrospective basis to existing hybrid financial instruments issued in the form of a share as of the beginning of the fiscal year for which the amendments are effective and shall be reported as a cumulative-effect adjustment directly to retained earnings as of the beginning of the year of adoption. The adoption of the amended guidance is not expected to have a material impact on the Condensed Consolidated Financial Statements.
	Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items
	In January 2015, the FASB issued amended guidance that eliminates the concept of extraordinary items from GAAP. Presently, an event or transaction is presumed to be an ordinary and usual activity of a reporting entity unless evidence clearly supports its classification as an extraordinary item, which must be both unusual in nature and infrequent in occurrence. An entity was required to segregate the extraordinary item from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. An entity was also required to disclose applicable income taxes and either present or disclose earnings-per-share data applicable to the extraordinary item. The presentation and disclosure guidance for items that are unusual in nature or occur infrequently will be retained and will be expanded to include items that are both unusual in nature and infrequently occurring. The amended guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The amended guidance may be applied prospectively or retrospectively to all periods presented in the financial statements. The adoption of the amended guidance is not expected to have a material impact on the Condensed Consolidated Financial Statements.
	Amendments to the Consolidation Analysis
	In February 2015, the FASB issued amended guidance that changes the analysis a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amended guidance 1) modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities; 2) eliminates the presumption that a general partner should consolidate a limited partnership; 3) affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and 4) provides a scope exception from consolidation guidance for reporting entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. The amended guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015, with early adoption permitted. The amended guidance may be applied using either a retrospective approach or a modified retrospective approach with a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. The Bancorp is currently in the process of evaluating the impact of adopting the amended guidance on the Condensed Consolidated Financial Statements.
	Simplifying the Presentation of Debt Issuance Costs
	In April 2015, the FASB issued amended guidance to address the different balance sheet presentation requirements for debt issuance costs and debt discounts and premiums. The amended guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amended guidance. The amended guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted for financial statements that have not been previously issued. The amended guidance should be applied retrospectively, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the amended guidance. The Bancorp currently has approximately $33 million of debt issuance costs recorded within Other Assets in the Condensed Consolidated Balance Sheets that will be required to be reclassified and presented as a direct deduction from the debt liability upon adoption of the amended guidance. The adoption of the amended guidance is not expected to have an impact on the Bancorp's Condensed Consolidated Statements of Income.

	CREDIT RISK PROFILE
	Commercial Portfolio Segment
	For purposes of monitoring the credit quality and risk characteristics of its commercial portfolio segment, the Bancorp disaggregates the segment into the following classes: commercial and industrial, commercial mortgage owner-occupied, commercial mortgage nonowner-occupied, commercial construction and commercial leasing.
	To facilitate the monitoring of credit quality within the commercial portfolio segment, and for purposes of analyzing historical loss rates used in the determination of the ALLL for the commercial portfolio segment, the Bancorp utilizes the following categories of credit grades: pass, special mention, substandard, doubtful or loss. The five categories, which are derived from standard regulatory rating definitions, are assigned upon initial approval of credit to borrowers and updated periodically thereafter.
	Pass ratings, which are assigned to those borrowers that do not have identified potential or well defined weaknesses and for which there is a high likelihood of orderly repayment, are updated at least annually based on the size and credit characteristics of the borrower. All other categories are updated on a quarterly basis during the month preceding the end of the calendar quarter.
	The Bancorp assigns a special mention rating to loans and leases that have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may, at some future date, result in the deterioration of the repayment prospects for the loan or lease or the Bancorp's credit position.
	The Bancorp assigns a substandard rating to loans and leases that are inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged. Substandard loans and leases have well defined weaknesses or weaknesses that could jeopardize the orderly repayment of the debt. Loans and leases in this grade also are characterized by the distinct possibility that the Bancorp will sustain some loss if the deficiencies noted are not addressed and corrected.
	The Bancorp assigns a doubtful rating to loans and leases that have all the attributes of a substandard rating with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonable specific pending factors that may work to the advantage of and strengthen the credit quality of the loan or lease, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors may include a proposed merger or acquisition, liquidation proceeding, capital injection, perfecting liens on additional collateral or refinancing plans.
	Loans and leases classified as loss are considered uncollectible and are charged-off in the period in which they are determined to be uncollectible. Because loans and leases in this category are fully charged-off, they are not included in the following tables.
	The following tables summarize the credit risk profile of the Bancorp’s commercial portfolio segment, by class:
					Special
	As of March 31, 2015 ($ in millions)		Pass		Mention		Substandard		Doubtful		Total

Consumer Portfolio Segment
For purposes of monitoring the credit quality and risk characteristics of its consumer portfolio segment, the Bancorp disaggregates the segment into the following classes: home equity, automobile loans, credit card, and other consumer loans and leases. The Bancorp's residential mortgage portfolio segment is also a separate class.
The Bancorp considers repayment performance as the best indicator of credit quality for residential mortgage and consumer loans, which includes both the delinquency status and performing versus nonperforming status of the loans. The delinquency status of all residential mortgage and consumer loans is presented by class in the age analysis section while the performing versus nonperforming status is presented in the table below. Refer to the nonaccrual loans and leases section of Note 1 in the Bancorp's Annual Report on Form 10-K for the year ended December 31, 2014 for additional delinquency and nonperforming information.
The following table presents a summary of the Bancorp’s residential mortgage and consumer portfolio segments, by class, disaggregated into performing versus nonperforming status as of:

Includes accrual and nonaccrual loans and leases.
Impaired Loans and Leases
Larger commercial loans and leases included within aggregate borrower relationship balances exceeding $1 million that exhibit probable or observed credit weaknesses are subject to individual review for impairment. The Bancorp also performs an individual review on loans and leases that are restructured in a TDR. The Bancorp considers the current value of collateral, credit quality of any guarantees, the loan structure, and other factors when evaluating whether an individual loan or lease is impaired. Other factors may include the geography and industry of the borrower, size and financial condition of the borrower, cash flow and leverage of the borrower, and the Bancorp's evaluation of the borrower's management. Smaller-balance homogenous loans or leases that are collectively evaluated for impairment are not included in the following tables.
The following tables summarize the Bancorp’s impaired loans and leases (by class) that were subject to individual review, which includes all loans and leases restructured in a TDR:

Excludes $2 and $39 of nonaccrual loans held for sale at March 31, 2015 and December 31, 2014, respectively.
Includes $9 of nonaccrual government insured commercial loans whose repayments are insured by the SBA at March 31, 2015 and December 31, 2014 and $4 of restructured nonaccrual government insured commercial loans at March 31, 2015 and December 31, 2014.
Excludes $42 and $71 of OREO related to government insured loans at March 31, 2015 and December 31, 2014, respectively. The Bancorp has historically excluded government guaranteed loans classified in OREO from its nonperforming asset disclosures. Upon the prospective adoption on January 1, 2015 of ASU 2014-14 “Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure,” government guaranteed loans meeting certain criteria will be reclassified to other receivables rather than OREO upon foreclosure. As of March 31, 2015, the Bancorp had $21 of government guaranteed loans classified as other receivables. Refer to Note 3 for further information on the adoption of this amended guidance.
The Bancorp's recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process according to local requirements of the applicable jurisdiction was $355 million as of March 31, 2015.
Troubled Debt Restructurings
If a borrower is experiencing financial difficulty, the Bancorp may consider, in certain circumstances, modifying the terms of their loan to maximize collection of amounts due. Within each of the Bancorp's loan classes, TDRs typically involve either a reduction of the stated interest rate of the loan, an extension of the loan's maturity date(s) with a stated rate lower than the current market rate for a new loan with similar risk, or in limited circumstances, a reduction of the principal balance of the loan or the loan's accrued interest. Modifying the terms of a loan may result in an increase or decrease to the ALLL depending upon the terms modified, the method used to measure the ALLL for a loan prior to modification, and whether any charge-offs were recorded on the loan before or at the time of modification. Refer to the ALLL section of Note 1 in the Bancorp's Annual Report on Form 10-K for the year ended December 31, 2014 for information on the Bancorp's ALLL methodology. Upon modification of a loan, the Bancorp measures the related impairment as the difference between the estimated future cash flows expected to be collected on the modified loan, discounted at the original effective yield of the loan, and the carrying value of the loan. The resulting measurement may result in the need for minimal or no valuation allowance because it is probable that all cash flows will be collected under the modified terms of the loan. In addition, if the stated interest rate was increased in a TDR, the cash flows on the modified loan, using the pre-modification interest rate as the discount rate, often exceed the recorded investment of the loan. Conversely, upon a modification that reduces the stated interest rate on a loan, the Bancorp recognizes an impairment loss as an increase to the ALLL. If a TDR involves a reduction of the principal balance of the loan or the loan's accrued interest, that amount is charged off to the ALLL.
As of March 31, 2015, the Bancorp had $56 million and $23 million in line of credit and letter of credit commitments, respectively, compared to $63 million and $26 million in line of credit and letter of credit commitments as of December 31, 2014, respectively, to lend additional funds to borrowers whose terms have been modified in a TDR.

Excludes all loans and leases held for sale and loans acquired with deteriorated credit quality which were accounted for within a pool.
Represents number of loans post-modification.
The Bancorp considers TDRs that become 90 days or more past due under the modified terms as subsequently defaulted. For commercial loans not subject to individual review for impairment, loss rates that are applied for purposes of determining the ALLL include historical losses associated with subsequent defaults on loans previously modified in a TDR. For consumer loans, the Bancorp performs a qualitative assessment of the adequacy of the consumer ALLL by comparing the consumer ALLL to forecasted consumer losses over the projected loss emergence period (the forecasted losses include the impact of subsequent defaults of consumer TDRs). When a residential mortgage, home equity, automobile or other consumer loan that has been modified in a TDR subsequently defaults, the present value of expected cash flows used in the measurement of the potential impairment loss is generally limited to the expected net proceeds from the sale of the loan's underlying collateral and any resulting impairment loss is reflected as a charge-off or an increase in ALLL. The Bancorp fully reserves for credit card loans modified in a TDR that subsequently default.
The following tables provide a summary of subsequent defaults of TDRs that occurred during the three months ended March 31, 2015 and 2014 and within 12 months of the restructuring date:

	At both March 31, 2015 and December 31, 2014, land and improvements included $165 million associated with parcels of undeveloped land intended for future branch expansion. The Bancorp monitors changing customer preferences associated with the channels it uses for banking transactions to evaluate the efficiency, competitiveness and quality of the customer service experience of its retail transaction network. As part of this ongoing assessment the Bancorp may determine that it is no longer fully committed to maintaining full-service branches at certain of its existing banking center locations. Similarly, the Bancorp may also determine that it is no longer fully committed to building banking centers on certain parcels of land which had previously been held for future branch expansion. In these circumstances, the Bancorp performs an assessment of the recoverability of these long-lived assets. Impairment losses associated with such assessments and lower of cost or market adjustments were $4 million for the three months ended March 31, 2015 and immaterial for the three months ended March 31, 2014. The Bancorp's assessment of the recoverability of these asset groups requires the exercise of judgment in projecting the extent and nature of their future use and the related cash flows which may be impacted by unanticipated events or circumstances.

	As part of a periodic review of long lived assets for impairment associated with operating lease assets, the Bancorp identified an impairment regarding certain medium and large cabin corporate aircraft subject to leases expiring in 2017 and later. After applying the appropriate tests under current accounting guidance, it was determined that such recoverability was in doubt and the assets had, in fact, been impaired. The impact of the impairment was $30 million which was recognized as a reduction to corporate banking revenue in the Condensed Consolidated Statements of Income during the three months ended March 31, 2015 as such diminution in value of the assets was associated with both the period ended March 31, 2015 and prior periods. The Bancorp assessed the materiality of this impairment and concluded it was immaterial to currently reported interim amounts and previously reported annual and interim amounts.

Variable Interest Entities
Variable Interest Entities	10. Variable Interest Entities
	The Bancorp, in the normal course of business, engages in a variety of activities that involve VIEs, which are legal entities that lack sufficient equity to finance their activities, or the equity investors of the entities as a group lack any of the characteristics of a controlling interest. The primary beneficiary of a VIE is generally the enterprise that has both the power to direct the activities most significant to the economic performance of the VIE and the obligation to absorb losses or receive benefits that could potentially be significant to the VIE. For certain investment funds, the primary beneficiary is the enterprise that will absorb a majority of the fund's expected losses or receive a majority of the fund's expected residual returns. The Bancorp evaluates its interests in certain entities to determine if these entities meet the definition of a VIE and whether the Bancorp is the primary beneficiary and should consolidate the entity based on the variable interests it held both at inception and when there is a change in circumstances that requires a reconsideration. If the Bancorp is determined to be the primary beneficiary of a VIE, it must account for the VIE as a consolidated subsidiary. If the Bancorp is determined not to be the primary beneficiary of a VIE but holds a variable interest in the entity, such variable interests are accounted for under the equity method of accounting or other accounting standards as appropriate.

	Automobile Loan Securitizations
	In securitization transactions that occurred during 2014, the Bancorp transferred an aggregate amount of $3.8 billion in consumer automobile loans to bankruptcy remote trusts which were deemed to be VIEs. The primary purposes of the VIEs were to issue asset-backed securities with varying levels of credit subordination and payment priority, as well as residual interests, and to provide the Bancorp with access to liquidity for its originated loans. The Bancorp retained residual interests in the VIEs and, therefore, has an obligation to absorb losses and a right to receive benefits from the VIEs that could potentially be significant to the VIEs. In addition, the Bancorp retained servicing rights for the underlying loans and, therefore, holds the power to direct the activities of the VIEs that most significantly impact the economic performance of the VIEs. As a result, the Bancorp concluded that it is the primary beneficiary of the VIEs and, therefore, has consolidated these VIEs. The assets of the VIEs are restricted to the settlement of the notes and other obligations of the VIEs. Third-party holders of the notes do not have recourse to the general assets of the Bancorp.
	The economic performance of the VIEs is most significantly impacted by the performance of the underlying loans. The principal risks to which the VIEs are exposed include credit risk and prepayment risk. The credit and prepayment risks are managed through credit enhancements in the form of reserve accounts, overcollateralization, excess interest on the loans and the subordination of certain classes of asset-backed securities to other classes.
	CDC Investments
	CDC, a wholly-owned indirect subsidiary of the Bancorp, was created to invest in projects to create affordable housing, revitalize business and residential areas, and preserve historic landmarks. CDC generally co-invests with other unrelated companies and/or individuals and typically makes investments in a separate legal entity that owns the property under development. The entities are usually formed as limited partnerships and LLCs, and CDC typically invests as a limited partner/investor member in the form of equity contributions. The economic performance of the VIEs is driven by the performance of their underlying investment projects as well as the VIEs' ability to operate in compliance with the rules and regulations necessary for the qualification of tax credits generated by equity investments. Typically, the general partner or managing member will be the party that has the right to make decisions that will most significantly impact the economic performance of the entity. The Bancorp's subsidiaries serve as the managing member of certain LLCs invested in business revitalization projects. The Bancorp has provided an indemnification guarantee to the investor member of these LLCs related to the qualification of tax credits generated by the investor members' investment. Accordingly, the Bancorp concluded that it is the primary beneficiary and, therefore, has consolidated these VIEs. As a result, the investor members' interests in these VIEs are presented as noncontrolling interests in the Condensed Consolidated Financial Statements. This presentation includes reporting separately the equity attributable to the noncontrolling interests in the Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Changes in Equity and reporting separately the comprehensive income attributable to the noncontrolling interests in the Condensed Consolidated Statements of Comprehensive Income and the net income attributable to the noncontrolling interests in the Condensed Consolidated Statements of Income. The Bancorp's maximum exposure related to these indemnifications at March 31, 2015 and December 31, 2014 was $25 million and $24 million, respectively, which is based on an amount required to meet the investor member's defined target rate of return.
	Non-consolidated VIEs
	The following tables provide a summary of assets and liabilities carried on the Condensed Consolidated Balance Sheets related to non-consolidated VIEs for which the Bancorp holds an interest, but is not the primary beneficiary of the VIE, as well as the Bancorp’s maximum exposure to losses associated with its interests in the entities as of:
			Total		Total		Maximum

	CDC investments	$	1,402		341		1,402

	Loans provided to VIEs		1,900		-		2,759
	Automobile loan securitization		2		-		2
	CDC Investments
	As noted previously, CDC typically invests in VIEs as a limited partner or investor member in the form of equity contributions. The Bancorp has determined that it is not the primary beneficiary of these VIEs because it lacks the power to direct the activities that most significantly impact the economic performance of the underlying project or the VIEs' ability to operate in compliance with the rules and regulations necessary for the qualification of tax credits generated by equity investments. This power is held by the general partners/managing members who exercise full and exclusive control of the operations of the VIEs. Accordingly, the Bancorp accounts for these investments under the equity method of accounting.
	The Bancorp's funding requirements are limited to its invested capital and any additional unfunded commitments for future equity contributions. The Bancorp's maximum exposure to loss as a result of its involvement with the VIEs is limited to the carrying amounts of the investments, including the unfunded commitments. The carrying amounts of these investments, which are included in other assets in the Condensed Consolidated Balance Sheets, and the liabilities related to the unfunded commitments, which are included in other liabilities in the Condensed Consolidated Balance Sheets, are included in the previous tables for all periods presented. The Bancorp has no other liquidity arrangements or obligations to purchase assets of the VIEs that would expose the Bancorp to a loss. In certain arrangements, the general partner/managing member of the VIE has guaranteed a level of projected tax credits to be received by the limited partners/investor members, thereby minimizing a portion of the Bancorp's risk.
	As of March 31, 2015 and December 31, 2014 the Bancorp's CDC investments included $1.2 billion and $1.3 billion, respectively, of investments in affordable housing tax credits recognized in other assets in the Condensed Consolidated Balance Sheets. The unfunded commitments related to these investments were $331 million and $357 million as of March 31, 2015 and December 31, 2014, respectively, which are expected to be funded from 2015 to 2031.
	The Bancorp has accounted for all of its investments in qualified affordable housing tax credits using the equity method of accounting. The following table summarizes the impact to the Condensed Consolidated Statements of Income relating to investments in qualified affordable housing investments:
				Affected Line Item in the Condensed				For the three months ended March 31,
	($ in millions)			Consolidated Statements of Income				2015	2014
	Pre-tax investment losses			Other noninterest expense			$	34	29
	Impairment losses(a)			Other noninterest expense				33	29
	Tax credits and other benefits			Applicable income tax expense				52	47
	The Bancorp did not recognize impairment losses resulting from the forfeiture or ineligibility of tax credits or other circumstances during the three months ended March 31, 2015 and 2014.
	Private Equity Investments
	The Bancorp, through a wholly owned subsidiary, invests as a limited partner in private equity funds which provide the Bancorp an opportunity to obtain higher rates of return on invested capital, while also creating cross-selling opportunities for the Bancorp's commercial products. Each of the limited partnerships has an unrelated third-party general partner responsible for appointing the fund manager. The Bancorp has not been appointed fund manager for any of these private equity funds. The funds finance primarily all of their activities from the partners' capital contributions and investment returns. Under the VIE consolidation guidance still applicable to the funds, the Bancorp has determined that it is not the primary beneficiary of the funds because it does not absorb a majority of the funds' expected losses or receive a majority of the funds' expected residual returns. Therefore, the Bancorp accounts for its investments in these limited partnerships under the equity method of accounting.
The Bancorp is exposed to losses arising from the negative performance of the underlying investments in the private equity funds. As a limited partner, the Bancorp's maximum exposure to loss is limited to the carrying amounts of the investments plus unfunded commitments. The carrying amounts of these investments, which are included in other assets in the Condensed Consolidated Balance Sheets, are included in the previous tables. Also, as of March 31, 2015 and December 31, 2014, the unfunded commitment amounts to the funds were $68 million and $78 million, respectively. The Bancorp made capital contributions of $10 million and $7 million, respectively, to private equity funds during the three months ended March 31, 2015 and 2014.
Loans Provided to VIEs
The Bancorp has provided funding to certain unconsolidated VIEs sponsored by third parties. These VIEs are generally established to finance certain consumer and small business loans originated by third parties. The entities are primarily funded through the issuance of a loan from the Bancorp or a syndication through which the Bancorp is involved. The sponsor/administrator of the entities is responsible for servicing the underlying assets in the VIEs. Because the sponsor/administrator, not the Bancorp, holds the servicing responsibilities, which include the establishment and employment of default mitigation policies and procedures, the Bancorp does not hold the power to direct the activities that most significantly impact the economic performance of the entity and, therefore, is not the primary beneficiary.
The principal risk to which these entities are exposed is credit risk related to the underlying assets. The Bancorp's maximum exposure to loss is equal to the carrying amounts of the loans and unfunded commitments to the VIEs. The Bancorp's outstanding loans to these VIEs, included in commercial loans in Note 5, are included in the previous tables for all periods presented. As of March 31, 2015 and December 31, 2014, the Bancorp's unfunded commitments to these entities were $957 million and $859 million, respectively. The loans and unfunded commitments to these VIEs are included in the Bancorp's overall analysis of the ALLL and reserve for unfunded commitments, respectively. The Bancorp does not provide any implicit or explicit liquidity guarantees or principal value guarantees to these VIEs.
Automobile Loan Securitization
The Bancorp previously securitized and sold certain automobile loans with a carrying amount of approximately $509 million in a transaction that qualified for sale accounting. The Bancorp has concluded that it is not the primary beneficiary of the trust because it has neither the obligation to absorb losses of the entity that could potentially be significant to the VIE nor the right to receive benefits from the entity that could potentially be significant to the VIE. The Bancorp is not required and does not currently intend to provide any additional financial support to the trust. Investors and creditors only have recourse to the assets held by the trust. The interest the Bancorp holds in the VIE relates to servicing rights which are included in the Condensed Consolidated Balance Sheets. The maximum exposure to loss is equal to the carrying value of the servicing asset.

	Residential Mortgage TDR Loan Sale
	In March of 2015, the Bancorp recognized a $37 million gain, included in other noninterest income in the Bancorp's Condensed Consolidated Statements of Income, on the sale of certain HFS residential mortgage loans with a carrying value of $568 million that were previously modified in a TDR. As part of this sale, the Bancorp provided certain standard representations and warranties. Additionally, the Bancorp did not obtain servicing responsibilities on the sales of these loans and the investors have no credit recourse to the Bancorp's other assets for failure of debtors to pay when due.
	Residential Mortgage Loan Sales
	The Bancorp sold fixed and adjustable rate residential mortgage loans during the three months ended March 31, 2015 and 2014. In those sales, the Bancorp obtained servicing responsibilities and the investors have no recourse to the Bancorp's other assets for failure of debtors to pay when due. The Bancorp receives annual servicing fees based on a percentage of the outstanding balance. The Bancorp identifies classes of servicing assets based on financial asset type and interest rates.
	Information related to residential mortgage loan sales and the Bancorp’s mortgage banking activity, which is included in mortgage banking net revenue in the Condensed Consolidated Statements of Income, is as follows:

	The Bancorp's projections of amortization expense shown below are based on existing asset balances and static key economic assumptions as of March 31, 2015. Future amortization expense may vary from these projections.
	Estimated amortization expense for the remainder of 2015 through 2019 is as follows:

	Temporary impairment or impairment recovery, affected through a change in the MSR valuation allowance, is captured as a component of mortgage banking net revenue in the Condensed Consolidated Statements of Income. The Bancorp maintains a non-qualifying hedging strategy to manage a portion of the risk associated with changes in the value of the MSR portfolio. This strategy may include the purchase of free-standing derivatives and various available-for-sale securities. The interest income, mark-to-market adjustments and gain or loss from sale activities associated with these portfolios are expected to economically hedge a portion of the change in value of the MSR portfolio caused by fluctuating discount rates, earnings rates and prepayment speeds. The fair value of the servicing asset is based on the present value of expected future cash flows.
	The following table displays the beginning and ending fair value of the servicing rights for the three months ended March 31:
	($ in millions)		2015		2014
	Fixed-rate residential mortgage loans:
	Beginning balance	$	823		929

	(Provision for) recovery of MSR impairment		-48		4
	As of March 31, 2015 and 2014, the key economic assumptions used in measuring the interests in residential mortgage loans that continued to be held by the Bancorp at the date of sale or securitization resulting from transactions completed during the three months ended were as follows:
			31-Mar-15								31-Mar-14
		Rate	Weighted-Average Life (in years)		Prepayment Speed (annual)		OAS Spread (bps)		Weighted-Average Default Rate		Weighted-Average Life (in years)	Prepayment Speed (annual)		Discount Rate (annual)		Weighted-Average Default Rate
	Residential mortgage loans:
	Servicing rights	Fixed	6.2		12.6	%	900		N/A		6.7	10.8	%	10	%	N/A
	Servicing rights	Adjustable	3.6		23.4		1,180		N/A		3.7	22.5		11.7		N/A
	During the first quarter of 2015, the Bancorp adopted an OAS valuation approach for valuing its MSRs. This approach projects servicing cash flows over multiple interest rate scenarios, which are then discounted at risk-adjusted rates. The change to the OAS valuation approach did not have a material impact on the valuation of the MSRs for the three months ended March 31, 2015.
	Based on historical credit experience, expected credit losses for residential mortgage loan servicing rights have been deemed immaterial, as the Bancorp sold the majority of the underlying loans without recourse. At March 31, 2015 and December 31, 2014, the Bancorp serviced $64.2 billion and $65.4 billion, respectively, of residential mortgage loans for other investors. The value of MSRs that continue to be held by the Bancorp is subject to credit, prepayment and interest rate risks on the sold financial assets.
	At March 31, 2015, the sensitivity of the current fair value of residual cash flows to immediate 10%, 20% and 50% adverse changes in prepayment speed assumptions and immediate 10% and 20% adverse changes in other assumptions are as follows:
								Prepayment							Residual Servicing
								Speed Assumption							Cash Flows
			Fair		Weighted-Average Life (in					Impact of Adverse Change on Fair Value				OAS			Impact of Adverse Change on Fair Value
($ in millions)(a)	Rate		Value		years)		Rate			10%	20%	50%		Spread (bps)			10%	20%
Residential mortgage loans:
Servicing rights	Fixed	$	759		6.4		10	%	$	-32	-62	-139		920		$	-25	-47
Servicing rights	Adjustable		29		2.6		32.2			-2	-4	-8		640			-	-1
The impact of the weighted-average default rate on the current fair value of residual cash flows for all scenarios is immaterial.
These sensitivities are hypothetical and should be used with caution. As the figures indicate, changes in fair value based on these variations in the assumptions typically cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. The Bancorp believes variations of these levels are reasonably possible; however, there is the potential that adverse changes in key assumptions could be even greater. Also, in the previous table, the effect of a variation in a particular assumption on the fair value of the interests that continue to be held by the Bancorp is calculated without changing any other assumption; in reality, changes in one factor may result in changes in another (for example, increases in market interest rates may result in lower prepayments), which might magnify or counteract these sensitivities.

Derivative Financial Instruments
Derivative Financial Instruments	12. Derivative Financial Instruments
	The Bancorp maintains an overall risk management strategy that incorporates the use of derivative instruments to reduce certain risks related to interest rate, prepayment and foreign currency volatility. Additionally, the Bancorp holds derivative instruments for the benefit of its commercial customers and for other business purposes. The Bancorp does not enter into unhedged speculative derivative positions.
	The Bancorp's interest rate risk management strategy involves modifying the repricing characteristics of certain financial instruments so that changes in interest rates do not adversely affect the Bancorp's net interest margin and cash flows. Derivative instruments that the Bancorp may use as part of its interest rate risk management strategy include interest rate swaps, interest rate floors, interest rate caps, forward contracts, options and swaptions. Interest rate swap contracts are exchanges of interest payments, such as fixed-rate payments for floating-rate payments, based on a stated notional amount and maturity date. Interest rate floors protect against declining rates, while interest rate caps protect against rising interest rates. Forward contracts are contracts in which the buyer agrees to purchase, and the seller agrees to make delivery of, a specific financial instrument at a predetermined price or yield. Options provide the purchaser with the right, but not the obligation, to purchase or sell a contracted item during a specified period at an agreed upon price. Swaptions are financial instruments granting the owner the right, but not the obligation, to enter into or cancel a swap.
	Prepayment volatility arises mostly from changes in fair value of the largely fixed-rate MSR portfolio, mortgage loans and mortgage-backed securities. The Bancorp may enter into various free-standing derivatives (principal-only swaps, interest rate swaptions, interest rate floors, mortgage options, TBAs and interest rate swaps) to economically hedge prepayment volatility. Principal-only swaps are total return swaps based on changes in the value of the underlying mortgage principal-only trust. TBAs are a forward purchase agreement for a mortgage-backed securities trade whereby the terms of the security are undefined at the time the trade is made.
	Foreign currency volatility occurs as the Bancorp enters into certain loans denominated in foreign currencies. Derivative instruments that the Bancorp may use to economically hedge these foreign denominated loans include foreign exchange swaps and forward contracts.
	The Bancorp also enters into derivative contracts (including foreign exchange contracts, commodity contracts and interest rate contracts) for the benefit of commercial customers and other business purposes. The Bancorp may economically hedge significant exposures related to these free-standing derivatives by entering into offsetting third-party contracts with approved, reputable counterparties with substantially matching terms and currencies. Credit risk arises from the possible inability of counterparties to meet the terms of their contracts. The Bancorp's exposure is limited to the replacement value of the contracts rather than the notional, principal or contract amounts. Credit risk is minimized through credit approvals, limits, counterparty collateral and monitoring procedures.
	The Bancorp's derivative assets include certain contractual features in which the Bancorp requires the counterparties to provide collateral in the form of cash and securities to offset changes in the fair value of the derivatives, including changes in the fair value due to credit risk of the counterparty. As of March 31, 2015 and December 31, 2014, the balance of collateral held by the Bancorp for derivative assets was $952 million and $830 million, respectively. The credit component negatively impacting the fair value of derivative assets associated with customer accommodation contracts as of March 31, 2015 and December 31, 2014 was $13 million and $16 million, respectively.
	In measuring the fair value of derivative liabilities, the Bancorp considers its own credit risk, taking into consideration collateral maintenance requirements of certain derivative counterparties and the duration of instruments with counterparties that do not require collateral maintenance. When necessary, the Bancorp posts collateral primarily in the form of cash and securities to offset changes in fair value of the derivatives, including changes in fair value due to the Bancorp's credit risk. As of March 31, 2015 and December 31, 2014, the balance of collateral posted by the Bancorp for derivative liabilities was $613 million and $574 million, respectively. Certain of the Bancorp's derivative liabilities contain credit-risk related contingent features that could result in the requirement to post additional collateral upon the occurrence of specified events. As of March 31, 2015, the fair value of the additional collateral that could be required to be posted as a result of the credit-risk related contingent features being triggered was immaterial to the Condensed Consolidated Financial Statements. The posting of collateral has been determined to remove the need for further consideration of credit risk. As a result, the Bancorp determined that the impact of the Bancorp's credit risk to the valuation of its derivative liabilities was immaterial to the Condensed Consolidated Financial Statements.
	The Bancorp holds certain derivative instruments that qualify for hedge accounting treatment and are designated as either fair value hedges or cash flow hedges. Derivative instruments that do not qualify for hedge accounting treatment, or for which hedge accounting is not established, are held as free-standing derivatives. All customer accommodation derivatives are held as free-standing derivatives.
	The fair value of derivative instruments is presented on a gross basis, even when the derivative instruments are subject to master netting arrangements. Derivative instruments with a positive fair value are reported in other assets in the Condensed Consolidated Balance Sheets while derivative instruments with a negative fair value are reported in other liabilities in the Condensed Consolidated Balance Sheets. Cash collateral payables and receivables associated with the derivative instruments are not added to or netted against the fair value amounts.

	Fair Value Hedges
The Bancorp may enter into interest rate swaps to convert its fixed-rate funding to floating-rate. Decisions to convert fixed-rate funding to floating are made primarily through consideration of the asset/liability mix of the Bancorp, the desired asset/liability sensitivity and interest rate levels. As of March 31, 2015, the assessment of hedge effectiveness for all interest rate swaps was performed using regression analysis and such swaps were accounted for using the “long-haul” method. The long-haul method requires a quarterly assessment of hedge effectiveness and measurement of ineffectiveness. For interest rate swaps accounted for as a fair value hedge using the long-haul method, ineffectiveness is the difference between the changes in the fair value of the interest rate swap and changes in fair value of the related hedged item attributable to the risk being hedged. The ineffectiveness on interest rate swaps hedging fixed-rate funding is reported within interest expense in the Condensed Consolidated Statements of Income.
The following table reflects the change in fair value of interest rate contracts, designated as fair value hedges, as well as the change in fair value of the related hedged items attributable to the risk being hedged, included in the Condensed Consolidated Statements of Income:

The Bancorp may enter into interest rate swaps to convert floating-rate assets and liabilities to fixed rates or to hedge certain forecasted transactions. The assets or liabilities may be grouped in circumstances where they share the same risk exposure for which the Bancorp desires to hedge. The Bancorp may also enter into interest rate caps and floors to limit cash flow variability of floating rate assets and liabilities. As of March 31, 2015, all hedges designated as cash flow hedges were assessed for effectiveness using regression analysis. Ineffectiveness is generally measured as the amount by which the cumulative change in the fair value of the hedging instrument exceeds the present value of the cumulative change in the hedged item's expected cash flows attributable to the risk being hedged. Ineffectiveness is reported within other noninterest income in the Condensed Consolidated Statements of Income. The effective portion of the cumulative gains or losses on cash flow hedges are reported within AOCI and are reclassified from AOCI to current period earnings when the forecasted transaction affects earnings. As of March 31, 2015, the maximum length of time over which the Bancorp is hedging its exposure to the variability in future cash flows is 57 months.
Reclassified gains and losses on interest rate contracts related to commercial and industrial loans are recorded within interest income in the Condensed Consolidated Statements of Income. As of March 31, 2015 and December 31, 2014, $47 million and $23 million, respectively, of net deferred gains, net of tax, on cash flow hedges were recorded in AOCI in the Condensed Consolidated Balance Sheets. As of March 31, 2015, approximately $44 million in net deferred gains, net of tax, recorded in AOCI are expected to be reclassified into earnings during the next twelve months. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to March 31, 2015.
During the three months ended March 31, 2015 and 2014, there were no gains or losses reclassified from AOCI into earnings associated with the discontinuance of cash flow hedges because it was probable that the original forecasted transaction would no longer occur by the end of the originally specified time period or within the additional period of time as defined by U.S. GAAP.

Free-Standing Derivative Instruments – Risk Management and Other Business Purposes
As part of its overall risk management strategy relative to its mortgage banking activity, the Bancorp may enter into various free-standing derivatives (principal-only swaps, interest rate swaptions, interest rate floors, mortgage options, TBAs and interest rate swaps) to economically hedge changes in fair value of its largely fixed-rate MSR portfolio. Principal-only swaps hedge the mortgage-LIBOR spread because these swaps appreciate in value as a result of tightening spreads. Principal-only swaps also provide prepayment protection by increasing in value when prepayment speeds increase, as opposed to MSRs that lose value in a faster prepayment environment. Receive fixed/pay floating interest rate swaps and swaptions increase in value when interest rates do not increase as quickly as expected.
The Bancorp enters into forward contracts and mortgage options to economically hedge the change in fair value of certain residential mortgage loans held for sale due to changes in interest rates. IRLCs issued on residential mortgage loan commitments that will be held for sale are also considered free-standing derivative instruments and the interest rate exposure on these commitments is economically hedged primarily with forward contracts. Revaluation gains and losses from free-standing derivatives related to mortgage banking activity are recorded as a component of mortgage banking net revenue in the Condensed Consolidated Statements of Income.
In conjunction with the initial sale of the Bancorp's 51% interest in Vantiv Holding, LLC, the Bancorp received a warrant which is accounted for as a free-standing derivative. Refer to Note 19 for further discussion of significant inputs and assumptions used in the valuation of the warrant.
In conjunction with the initial sale of Visa, Inc. Class B shares in 2009, the Bancorp entered into a total return swap in which the Bancorp will make or receive payments based on subsequent changes in the conversion rate of the Class B shares into Class A shares. This total return swap is accounted for as a free-standing derivative. Refer to Note 19 for further discussion of significant inputs and assumptions used in the valuation of this instrument.
The net gains (losses) recorded in the Condensed Consolidated Statements of Income relating to free-standing derivative instruments used for risk management and other business purposes are summarized in the following table:

Free-Standing Derivative Instruments – Customer Accommodation
The majority of the free-standing derivative instruments the Bancorp enters into are for the benefit of its commercial customers. These derivative contracts are not designated against specific assets or liabilities on the Condensed Consolidated Balance Sheets or to forecasted transactions and, therefore, do not qualify for hedge accounting. These instruments include foreign exchange derivative contracts entered into for the benefit of commercial customers involved in international trade to hedge their exposure to foreign currency fluctuations and commodity contracts to hedge such items as natural gas and various other derivative contracts. The Bancorp may economically hedge significant exposures related to these derivative contracts entered into for the benefit of customers by entering into offsetting contracts with approved, reputable, independent counterparties with substantially matching terms. The Bancorp hedges its interest rate exposure on commercial customer transactions by executing offsetting swap agreements with primary dealers. Revaluation gains and losses on interest rate, foreign exchange, commodity and other commercial customer derivative contracts are recorded as a component of corporate banking revenue in the Condensed Consolidated Statements of Income.
The Bancorp enters into risk participation agreements, under which the Bancorp assumes credit exposure relating to certain underlying interest rate derivative contracts. The Bancorp only enters into these risk participation agreements in instances in which the Bancorp has participated in the loan that the underlying interest rate derivative contract was designed to hedge. The Bancorp will make payments under these agreements if a customer defaults on its obligation to perform under the terms of the underlying interest rate derivative contract. As of March 31, 2015 and December 31, 2014, the total notional amount of the risk participation agreements was $1.2 billion and $1.1 billion, respectively, and the fair value was a liability of $2 million at March 31, 2015 and December 31, 2014, respectively, which is included in interest rate contracts for customers. As of March 31, 2015, the risk participation agreements had an average remaining life of 2.3 years.
The Bancorp's maximum exposure in the risk participation agreements is contingent on the fair value of the underlying interest rate derivative contracts in an asset position at the time of default. The Bancorp monitors the credit risk associated with the underlying customers in the risk participation agreements through the same risk grading system currently utilized for establishing loss reserves in its loan and lease portfolio.
Risk ratings of the notional amount of risk participation agreements under this risk rating system are summarized in the following table as of:

Offsetting Derivative Financial Instruments
The Bancorp's derivative transactions are generally governed by ISDA Master Agreements and similar arrangements, which include provisions governing the setoff of assets and liabilities between the parties. When the Bancorp has more than one outstanding derivative transaction with a single counterparty, the setoff provisions contained within these agreements generally allow the non-defaulting party the right to reduce its liability to the defaulting party by amounts eligible for setoff, including the collateral received as well as eligible offsetting transactions with that counterparty, irrespective of the currency, place of payment, or booking office. The Bancorp's policy is to present its derivative assets and derivative liabilities in the Condensed Consolidated Balance Sheets on a gross basis, even when provisions allowing for setoff are in place.
Collateral amounts included in the tables below consist primarily of cash and highly-rated government-backed securities.

	Accelerated Share Repurchase Transactions
	During the three months ended March 31, 2015, the Bancorp entered into or settled a number of accelerated share repurchase transactions. As part of these transactions, the Bancorp entered into forward contracts in which the final number of shares delivered at settlement was based generally on a discount to the average daily volume weighted average price of the Bancorp's common stock during the term of these repurchase agreements. The accelerated share repurchases were treated as two separate transactions (i) the acquisition of treasury shares on the acquisition date and (ii) a forward contract indexed to the Bancorp's stock.

	The Bancorp, in the normal course of business, enters into financial instruments and various agreements to meet the financing needs of its customers. The Bancorp also enters into certain transactions and agreements to manage its interest rate and prepayment risks, provide funding, equipment and locations for its operations and invest in its communities. These instruments and agreements involve, to varying degrees, elements of credit risk, counterparty risk and market risk in excess of the amounts recognized in the Condensed Consolidated Balance Sheets. The creditworthiness of counterparties for all instruments and agreements is evaluated on a case-by-case basis in accordance with the Bancorp's credit policies. The Bancorp's significant commitments, contingent liabilities and guarantees in excess of the amounts recognized in the Condensed Consolidated Balance Sheets are discussed in further detail below:
	Commitments
	The Bancorp has certain commitments to make future payments under contracts. The following table reflects a summary of significant commitments as of:
			March 31,		December 31,
	($ in millions)		2015		2014
	Commitments to extend credit	$	64,425		63,827

	Capital commitments for private equity investments		68		78
	Capital expenditures		37		37
	Capital lease obligations		30		28
	Commitments to extend credit
	Commitments to extend credit are agreements to lend, typically having fixed expiration dates or other termination clauses that may require payment of a fee. Since many of the commitments to extend credit may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements. The Bancorp is exposed to credit risk in the event of nonperformance by the counterparty for the amount of the contract. Fixed-rate commitments are also subject to market risk resulting from fluctuations in interest rates and the Bancorp's exposure is limited to the replacement value of those commitments. As of March 31, 2015 and December 31, 2014, the Bancorp had a reserve for unfunded commitments, including letters of credit, totaling $130 million and $135 million, respectively, included in other liabilities in the Condensed Consolidated Balance Sheets. The Bancorp monitors the credit risk associated with commitments to extend credit using the same risk rating system utilized within its loan and lease portfolio.
	Risk ratings under this risk rating system are summarized in the following table as of:
			March 31,		December 31,
	($ in millions)		2015		2014

	Total	$	64,425		63,827
	Letters of credit
	Standby and commercial letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party and expire as summarized in the following table as of March 31, 2015:
	($ in millions)
	Less than 1 year(a)	$	2,245
	1 - 5 years(a)		1,484
	Over 5 years		52
	Total	$	3,781
	Includes $84 and $22 issued on behalf of commercial customers to facilitate trade payments in U.S. dollars and foreign currencies which expire less than one year and between one and five years, respectively.
	Standby letters of credit accounted for 97% of total letters of credit at March 31, 2015 and December 31, 2014 and are considered guarantees in accordance with U.S. GAAP. Approximately 61% and 60% of the total standby letters of credit were collateralized as of March 31, 2015 and December 31, 2014, respectively. In the event of nonperformance by the customers, the Bancorp has rights to the underlying collateral, which can include commercial real estate, physical plant and property, inventory, receivables, cash and marketable securities. The reserve related to these standby letters of credit, which was included in the total reserve for unfunded commitments, was immaterial at March 31, 2015 and $1 million at December 31, 2014. The Bancorp monitors the credit risk associated with letters of credit using the same risk rating system utilized within its loan and lease portfolio.
	Risk ratings under this risk rating system are summarized in the following table as of:
			March 31,		December 31,
	($ in millions)		2015		2014

	Total	$	3,781		3,974
	At March 31, 2015 and December 31, 2014, the Bancorp had outstanding letters of credit that were supporting certain securities issued as VRDNs. The Bancorp facilitates financing for its commercial customers, which consist of companies and municipalities, by marketing the VRDNs to investors. The VRDNs pay interest to holders at a rate of interest that fluctuates based upon market demand. The VRDNs generally have long-term maturity dates, but can be tendered by the holder for purchase at par value upon proper advance notice. When the VRDNs are tendered, a remarketing agent generally finds another investor to purchase the VRDNs to keep the securities outstanding in the market. As of March 31, 2015 and December 31, 2014, total VRDNs in which the Bancorp was the remarketing agent or were supported by a Bancorp letter of credit were $1.5 billion and $1.7 billion, respectively, of which FTS acted as the remarketing agent to issuers on $1.3 billion and $1.4 billion, respectively. As remarketing agent, FTS is responsible for finding purchasers for VRDNs that are put by investors. The Bancorp issued letters of credit, as a credit enhancement, to $1.1 billion and $1.2 billion of the VRDNs remarketed by FTS, in addition to $234 million and $247 million in VRDNs remarketed by third parties at March 31, 2015 and December 31, 2014, respectively. These letters of credit are included in the total letters of credit balance provided in the previous table. The Bancorp held $20 million and an immaterial amount of these VRDNs in its portfolio and classified them as trading securities at March 31, 2015 and December 31, 2014, respectively.
	Forward contracts to sell mortgage loans
	The Bancorp enters into forward contracts to economically hedge the change in fair value of certain residential mortgage loans held for sale due to changes in interest rates. The outstanding notional amounts of these forward contracts are included in the summary of significant commitments table for all periods presented.
	Noncancelable operating lease obligations and other commitments
	The Bancorp's subsidiaries have entered into a number of noncancelable lease agreements. The minimum rental commitments under noncancelable lease agreements are shown in the summary of significant commitments table. The Bancorp has also entered into a limited number of agreements for work related to banking center construction and to purchase goods or services.
	Contingent Liabilities
	Private mortgage reinsurance
	For certain mortgage loans originated by the Bancorp, borrowers may be required to obtain PMI provided by third-party insurers. In some instances, these insurers cede a portion of the PMI premiums to the Bancorp, and the Bancorp provides reinsurance coverage within a specified range of the total PMI coverage. The Bancorp's reinsurance coverage typically ranges from 5% to 10% of the total PMI coverage. The Bancorp's maximum exposure in the event of nonperformance by the underlying borrowers is equivalent to the Bancorp's total outstanding reinsurance coverage, which was $28 million at March 31, 2015 and $29 million at December 31, 2014. As of March 31, 2015 and December 31, 2014, the Bancorp maintained a reserve of $2 million related to exposures within the reinsurance portfolio which was included in other liabilities in the Condensed Consolidated Balance Sheets. During 2009, the Bancorp suspended the practice of providing reinsurance of PMI for newly originated mortgage loans.
	Legal claims
	There are legal claims pending against the Bancorp and its subsidiaries that have arisen in the normal course of business. Refer to Note 15 for additional information regarding these proceedings.
	Guarantees
	The Bancorp has performance obligations upon the occurrence of certain events under financial guarantees provided in certain contractual arrangements as discussed in the following sections.
	Residential mortgage loans sold with representation and warranty provisions
	Conforming residential mortgage loans sold to unrelated third parties are generally sold with representation and warranty provisions. A contractual liability arises only in the event of a breach of these representations and warranties and, in general, only when a loss results from the breach. The Bancorp may be required to repurchase any previously sold loan or indemnify (make whole) the investor or insurer for which the representation or warranty of the Bancorp proves to be inaccurate, incomplete or misleading.
	The Bancorp establishes a residential mortgage repurchase reserve related to various representations and warranties that reflects management's estimate of losses based on a combination of factors. The Bancorp's estimation process requires management to make subjective and complex judgments about matters that are inherently uncertain, such as future demand expectations, economic factors and the specific characteristics of the loans subject to repurchase. Such factors incorporate historical investor audit and repurchase demand rates, appeals success rates, historical loss severity and any additional information obtained from the GSEs regarding future mortgage repurchase and file request criteria. At the time of a loan sale, the Bancorp records a representation and warranty reserve at the estimated fair value of the Bancorp's guarantee and continually updates the reserve during the life of the loan as losses in excess of the reserve become probable and reasonably estimable. The provision for the estimated fair value of the representation and warranty guarantee arising from the loan sales is recorded as an adjustment to the gain on sale, which is included in noninterest income at the time of sale. Updates to the reserve are recorded in other noninterest expense.
	During the fourth quarter of 2013, the Bancorp settled certain repurchase claims related to mortgage loans originated and sold to FHLMC prior to January 1, 2009 for $25 million, after paid claim credits and other adjustments. The settlement removes the Bancorp's responsibility to repurchase or indemnify FHLMC for representation and warranty violations on any loan sold prior to January 1, 2009 except in limited circumstances.
	As of March 31, 2015 and December 31, 2014, the Bancorp maintained reserves related to loans sold with representation and warranty provisions totaling $36 million and $35 million, respectively, included in other liabilities in the Condensed Consolidated Balance Sheets.
	The Bancorp uses the best information available to it in estimating its mortgage representation and warranty reserve; however, the estimation process is inherently uncertain and imprecise and, accordingly, losses in excess of the amounts reserved as of March 31, 2015, are reasonably possible. The Bancorp currently estimates that it is reasonably possible that it could incur losses related to mortgage representation and warranty provisions in an amount up to approximately $44 million in excess of amounts reserved. This estimate was derived by modifying the key assumptions previously discussed to reflect management's judgment regarding reasonably possible adverse changes to those assumptions. The actual repurchase losses could vary significantly from the recorded mortgage representation and warranty reserve or this estimate of reasonably possibly losses, depending on the outcome of various factors, including those previously discussed.
	For the three months ended March 31, 2015 and 2014, the Bancorp paid $1 million and $7 million, respectively, in the form of make whole payments and repurchased $9 million and $23 million, respectively, in outstanding principal of loans to satisfy investor demands. Total repurchase demand requests during the three months ended March 31, 2015 and 2014 were $9 million and $35 million, respectively. Total outstanding repurchase demand inventory was $4 million at March 31, 2015 compared to $7 million at December 31, 2014.
	The following table summarizes activity in the reserve for representation and warranty provisions:

Residential mortgage loans sold with credit recourse
The Bancorp sold certain residential mortgage loans in the secondary market with credit recourse. In the event of any customer default, pursuant to the credit recourse provided, the Bancorp is required to reimburse the third party. The maximum amount of credit risk in the event of nonperformance by the underlying borrowers is equivalent to the total outstanding balance. In the event of nonperformance, the Bancorp has rights to the underlying collateral value securing the loan. The outstanding balances on these loans sold with credit recourse were $535 million and $548 million at March 31, 2015 and December 31, 2014, respectively, and the delinquency rates were 3.4% at March 31, 2015 and 4.0% at December 31, 2014. The Bancorp maintained an estimated credit loss reserve on these loans sold with credit recourse of $10 million and $11 million at March 31, 2015 and December 31, 2014, respectively, recorded in other liabilities in the Condensed Consolidated Balance Sheets. To determine the credit loss reserve, the Bancorp used an approach that is consistent with its overall approach in estimating credit losses for various categories of residential mortgage loans held in its loan portfolio.
Margin accounts
FTS, a subsidiary of the Bancorp, guarantees the collection of all margin account balances held by its brokerage clearing agent for the benefit of its customers. FTS is responsible for payment to its brokerage clearing agent for any loss, liability, damage, cost or expense incurred as a result of customers failing to comply with margin or margin maintenance calls on all margin accounts. The margin account balance held by the brokerage clearing agent was $14 million and $13 million at March 31, 2015 and December 31, 2014, respectively. In the event of any customer default, FTS has rights to the underlying collateral provided. Given the existence of the underlying collateral provided and negligible historical credit losses, the Bancorp does not maintain a loss reserve related to the margin accounts.
Long-term borrowing obligations
The Bancorp had certain fully and unconditionally guaranteed long-term borrowing obligations issued by wholly-owned issuing trust entities of $62 million at March 31, 2015 and December 31, 2014.
Visa litigation
The Bancorp, as a member bank of Visa prior to Visa's reorganization and IPO (the “IPO”) of its Class A common shares (the “Class A Shares”) in 2008, had certain indemnification obligations pursuant to Visa's certificate of incorporation and by-laws and in accordance with their membership agreements. In accordance with Visa's by-laws prior to the IPO, the Bancorp could have been required to indemnify Visa for the Bancorp's proportional share of losses based on the pre-IPO membership interests. As part of its reorganization and IPO, the Bancorp's indemnification obligation was modified to include only certain known or anticipated litigation (the “Covered Litigation”) as of the date of the restructuring. This modification triggered a requirement for the Bancorp to recognize a liability equal to the fair value of the indemnification liability.
In conjunction with the IPO, the Bancorp received 10.1 million of Visa's Class B common shares (the “Class B Shares”) based on the Bancorp's membership percentage in Visa prior to the IPO. The Class B Shares are not transferable (other than to another member bank) until the later of the third anniversary of the IPO closing or the date which the Covered Litigation has been resolved; therefore, the Bancorp's Class B Shares were classified in other assets and accounted for at their carryover basis of $0. Visa initially deposited $3 billion of the proceeds from the IPO into a litigation escrow account, established for the purpose of funding judgments in, or settlements of, the Covered Litigation. Since then, when Visa's litigation committee determined that the escrow account was insufficient, Visa issued additional Class A Shares and deposited the proceeds from the sale of the Class A Shares into the litigation escrow account. When Visa funded the litigation escrow account, the Class B Shares were subjected to dilution through an adjustment in the conversion rate of Class B Shares into Class A Shares.
In 2009, the Bancorp completed the sale of Visa, Inc. Class B Shares and entered into a total return swap in which the Bancorp will make or receive payments based on subsequent changes in the conversion rate of the Class B Shares into Class A Shares. The swap terminates on the later of the third anniversary of Visa's IPO or the date on which the Covered Litigation is settled. Refer to Note 19 for additional information on the valuation of the swap. The counterparty to the swap as a result of its ownership of the Class B Shares will be impacted by dilutive adjustments to the conversion rate of the Class B Shares into Class A Shares caused by any Covered Litigation losses in excess of the litigation escrow account. If actual judgments in, or settlements of, the Covered Litigation significantly exceed current expectations, then additional funding by Visa of the litigation escrow account and the resulting dilution of the Class B Shares could result in a scenario where the Bancorp's ultimate exposure associated with the Covered Litigation (the “Visa Litigation Exposure”) exceeds the value of the Class B Shares owned by the swap counterparty (the “Class B Value”). In the event the Bancorp concludes that it is probable that the Visa Litigation Exposure exceeds the Class B Value, the Bancorp would record a litigation reserve liability and a corresponding amount of other noninterest expense for the amount of the excess. Any such litigation reserve liability would be separate and distinct from the fair value derivative liability associated with the total return swap.
As of the date of the Bancorp's sale of Visa Class B Shares and through March 31, 2015, the Bancorp has concluded that it is not probable that the Visa Litigation Exposure will exceed the Class B value. Based on this determination, upon the sale of Class B Shares, the Bancorp reversed its net Visa litigation reserve liability and recognized a free-standing derivative liability associated with the total return swap. The fair value of the swap liability was $60 million at March 31, 2015 and $49 million at December 31, 2014. Refer to Notes 12 and 15 for further information.
After the Bancorp's sale of Visa Class B Shares, Visa has funded additional amounts into the litigation escrow account which have resulted in further dilution in the conversion of Class B Shares into Class A Shares, and along with other terms of the total return swap, required the Bancorp to make cash payments to the swap counterparty as follows:

Legal And Regulatory Proceedings
Legal and Regulatory Proceedings	15. Legal and Regulatory Proceedings
	During April 2006, the Bancorp was added as a defendant in a consolidated antitrust class action lawsuit originally filed against Visa®, MasterCard® and several other major financial institutions in the United States District Court for the Eastern District of New York. The plaintiffs, merchants operating commercial businesses throughout the U.S. and trade associations, claimed that the interchange fees charged by card-issuing banks were unreasonable and sought injunctive relief and unspecified damages. In addition to being a named defendant, the Bancorp is also subject to a possible indemnification obligation of Visa as discussed in Note 14 and has also entered into judgment and loss sharing agreements with Visa, MasterCard and certain other named defendants. In October 2012, the parties to the litigation entered into a settlement agreement. The court entered a Class Settlement Preliminary Approval Order in November 2012. Pursuant to the terms of the settlement agreement, the Bancorp paid $46 million into a class settlement escrow account. Previously, the Bancorp paid an additional $4 million in another settlement escrow in connection with the settlement of claims from plaintiffs not included in the class action. More than 7,900 merchants have requested exclusion from the class settlement. Pursuant to the terms of the settlement agreement, 25% of the funds paid into the class settlement escrow account have been returned to the control of the defendants through Class Exclusion Takedown Payments. Approximately 460 of the merchants who requested exclusion from the class have filed separate federal lawsuits against Visa, MasterCard and certain other defendants alleging similar antitrust violations. These “opt-out” federal lawsuits have been transferred to the United States District Court for the Eastern District of New York. The Bancorp was not named as a defendant in any of the opt-out federal lawsuits, but may have obligations pursuant to indemnification arrangements and/or the judgment or loss sharing agreements noted above. In addition, one merchant filed a separate state court lawsuit against Visa, MasterCard and certain other defendants, including the Bancorp, alleging similar antitrust violations. On January 14, 2014, the court entered a final order approving the class settlement. A number of merchants have filed appeals from that approval. On July 18, 2014, the court in which all but one of the opt-out federal lawsuits have been consolidated denied defendants' motion to dismiss the complaints. Several of the opt-out federal lawsuits have been resolved. Refer to Note 14.
	In 2008, two cases were filed in the United States District Court for the Southern District of Ohio against the Bancorp and certain officers styled Dudenhoeffer v Fifth Third Bancorp et al. Case No. 1:08-cv-538. The complaints alleged violations of ERISA based on allegations similar to those set forth in the previously reported securities class action cases. The ERISA actions were dismissed by the trial court, but the Sixth Circuit Court of Appeals reversed the trial court decision. The Bancorp petitioned the United States Supreme Court to review and reverse the Sixth Circuit decision and sought a stay of proceedings in the trial court pending appeal. On December 13, 2013, the Supreme Court granted certiorari and agreed to hear the appeal. Oral arguments were held on April 2, 2014 and on June 25, 2014 the Supreme Court unanimously vacated the Sixth Circuit decision and remanded the case for further proceedings consistent with the standards articulated in its decision.  The Supreme Court issued its mandate remanding the case back to the Sixth Circuit Court of Appeals but no further proceedings have occurred.
	In November 2014, a shareholder of the Bancorp filed a shareholder derivative suit in the Court of Common Pleas for Hamilton County, Ohio, against current and former members of the Bancorp's Board of Directors, the Bancorp's former Chief Financial Officer and current Executive Vice President, Daniel T. Poston, the Bancorp's Chief Executive Officer, Kevin T. Kabat, and, nominally, the Bancorp. The suit alleges breach of fiduciary duty, waste of corporate assets and unjust enrichment in connection with the Bancorp's alleged violations of federal and state securities laws, among other charges, in relation to its administrative settlement with the United States Securities and Exchange Commission announced on December 4, 2013 to resolve the previously reported investigation of the Bancorp's historical accounting and reporting with respect to certain commercial loans that were sold or reclassified as held for sale by the Company in the fourth quarter of 2008. The suit seeks, among other things, unspecified monetary damages, disgorgement of profits, certain corporate governance and personnel actions and compliance and disclosure changes. On January 16, 2015, a motion to dismiss the complaint was filed on behalf of all defendants, which the plaintiff opposed. The impact of the final disposition of this lawsuit cannot be assessed at this time.
	The Bancorp and its subsidiaries are not parties to any other material litigation. However, there are other litigation matters that arise in the normal course of business. While it is impossible to ascertain the ultimate resolution or range of financial liability with respect to these contingent matters, management believes any resulting liability from these other actions would not have a material effect upon the Bancorp's consolidated financial position, results of operations or cash flows.
	The Bancorp and/or its affiliates are involved in information-gathering requests, reviews, investigations and proceedings (both formal and informal) by various governmental regulatory agencies and law enforcement authorities, as well as self-regulatory bodies regarding their respective businesses. Additional matters will likely arise from time to time. Any of these matters may result in material adverse consequences to the Bancorp, its affiliates and/or their respective directors, officers and other personnel, including adverse judgments, findings, settlements, fines, penalties, orders, injunctions or other actions, amendments and/or restatements of the Bancorp's SEC filings and/or financial statements, as applicable, and/or determinations of material weaknesses in our disclosure controls and procedures. Investigations by regulatory authorities may from time to time result in civil or criminal referrals to law enforcement authorities such as the Department of Justice or a United States Attorney. Among other matters, the Bancorp has been cooperating with the Department of Justice, the Department of Housing and Urban Development and the Federal Housing Finance Authority in civil investigations regarding compliance with requirements relating to certain Federal Housing Agency-insured loans and certain loans sold to government sponsored entities originated by affiliates of the Bancorp. The investigations could lead to liability under the Federal False Claims Act and the Federal Financial Institutions Reform, Recovery and Enforcement Act of 1989, which allow up to treble and other special damages substantially in excess of actual losses. Additionally, the Bancorp is also cooperating with an investigation by the Department of Justice to determine whether the Bank engaged in any discriminatory practices in connection with the Bank's indirect automobile loan portfolio. Any claim resulting from this investigation could include direct and indirect damages and civil money penalties.
	The Bancorp is party to numerous claims and lawsuits as well as threatened or potential actions or claims concerning matters arising from the conduct of its business activities. The outcome of claims or litigation and the timing of ultimate resolution are inherently difficult to predict. The following factors, among others, contribute to this lack of predictability: plaintiff claims often include significant legal uncertainties, damages alleged by plaintiffs are often unspecified or overstated, discovery may not have started or may not be complete and material facts may be disputed or unsubstantiated. As a result of these factors, the Bancorp is not always able to provide an estimate of the range of reasonably possible outcomes for each claim. An accrual for a potential litigation loss is established when information related to the loss contingency indicates both that a loss is probable and that the amount of loss can be reasonably estimated. Any such accrual is adjusted from time to time thereafter as appropriate to reflect changes in circumstances. The Bancorp also determines, when possible (due to the uncertainties described above), estimates of reasonably possible losses or ranges of reasonably possible losses, in excess of amounts accrued. Under U.S. GAAP, an event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely” and an event is “remote” if “the chance of the future event or events occurring is slight.” Thus, references to the upper end of the range of reasonably possible loss for cases in which the Bancorp is able to estimate a range of reasonably possible loss mean the upper end of the range of loss for cases for which the Bancorp believes the risk of loss is more than slight. For matters where the Bancorp is able to estimate such possible losses or ranges of possible losses, the Bancorp currently estimates that it is reasonably possible that it could incur losses related to legal and regulatory proceedings including the matters discussed above in an aggregate amount up to approximately $61 million in excess of amounts accrued, with it also being reasonably possible that no losses will be incurred in these matters. The estimates included in this amount are based on the Bancorp's analysis of currently available information, and as new information is obtained the Bancorp may change its estimates.
	For these matters and others where an unfavorable outcome is reasonably possible but not probable, there may be a range of possible losses in excess of the established accrual that cannot be estimated. Based on information currently available, advice of counsel, available insurance coverage and established accruals, the Bancorp believes that the eventual outcome of the actions against the Bancorp and/or its subsidiaries, including the matters described above, will not, individually or in the aggregate, have a material adverse effect on the Bancorp's consolidated financial position. However, in the event of unexpected future developments, it is possible that the ultimate resolution of those matters, if unfavorable, may be material to the Bancorp's results of operations for any particular period, depending, in part, upon the size of the loss or liability imposed and the operating results for the applicable period.

Income Taxes	16. Income Taxes
	The Bancorp's provision for income taxes was $124 million and $119 million for the three months ended March 31, 2015 and 2014, respectively. The effective tax rates for the three months ended March 31, 2015 and 2014 were 25.6% and 27.3%, respectively. The decrease in the effective tax rate for the three months ended March 31, 2015 compared to the same period in the prior year included the benefit from an increase in the amount of 2015 forecasted income tax credits.
	While it is reasonably possible that the amount of the unrecognized tax benefits with respect to certain of the Bancorp's uncertain tax positions could increase or decrease during the next 12 months, the Bancorp believes it is unlikely that its unrecognized tax benefits will change by a material amount during the next 12 months.

	Shares are excluded from the computation of net income per diluted share when their inclusion has an anti-dilutive effect on earnings per share. The diluted earnings per share computation for the three months ended March 31, 2015 and 2014 excludes 18 million and 11 million, respectively, of SARs and an immaterial amount of stock options because their inclusion would have been anti-dilutive.
	The diluted earnings per share computation for the three months ended March 31, 2015 excludes the impact of the forward contract related to the January 27, 2015 accelerated share repurchase transaction. Based upon the average daily volume weighted average price of the Bancorp's common stock during the first quarter of 2015, the counterparty to the transaction would have been required to deliver additional shares for the settlement of the forward contract as of March 31, 2015, and thus the impact of the accelerated share repurchase transaction would have been anti-dilutive to earnings per share.

Fair Value Measurements
Fair Value Measurements	19. Fair Value Measurements
	The Bancorp measures certain financial assets and liabilities at fair value in accordance with U.S. GAAP, which defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP also establishes a fair value hierarchy, which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the instrument's fair value measurement. For more information regarding the fair value hierarchy, refer to Note 1 in the Bancorp's Annual Report on Form 10-K for the year ended December 31, 2014.

During the three months ended March 31, 2015 and the year ended December 31, 2014, no assets or liabilities were transferred between Level 1 and Level 2.
The following is a description of the valuation methodologies used for significant instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy.
Available-for-sale and other securities and trading securities
Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include government bonds and exchange traded equities. If quoted market prices are not available, then fair values are estimated using pricing models, quoted prices of securities with similar characteristics, or DCFs. Examples of such instruments, which are classified within Level 2 of the valuation hierarchy, include federal agencies, obligations of states and political subdivisions, agency residential mortgage-backed securities, agency and non-agency commercial mortgage-backed securities and asset-backed securities and other debt securities. Corporate bonds are included in asset-backed securities and other debt securities in the previous table. Federal agencies, obligations of states and political subdivisions, agency residential mortgage-backed securities, agency and non-agency commercial mortgage-backed securities and asset-backed securities and other debt securities are generally valued using a market approach based on observable prices of securities with similar characteristics.
Residential mortgage loans held for sale
For residential mortgage loans held for sale for which the fair value election has been made, fair value is estimated based upon mortgage-backed securities prices and spreads to those prices or, for certain ARM loans, DCF models that may incorporate the anticipated portfolio composition, credit spreads of asset-backed securities with similar collateral and market conditions. The anticipated portfolio composition includes the effect of interest rate spreads and discount rates due to loan characteristics such as the state in which the loan was originated, the loan amount and the ARM margin. Residential mortgage loans held for sale that are valued based on mortgage-backed securities prices are classified within Level 2 of the valuation hierarchy as the valuation is based on external pricing for similar instruments. ARM loans classified as held for sale are also classified within Level 2 of the valuation hierarchy due to the use of observable inputs in the DCF model. These observable inputs include interest rate spreads from agency mortgage-backed securities, market rates and observable discount rates.
Residential mortgage loans
Residential mortgage loans held for sale that are reclassified to held for investment are transferred from Level 2 to Level 3 of the fair value hierarchy. It is the Bancorp's policy to value any transfers between levels of the fair value hierarchy based on end of period fair values.
For residential mortgage loans reclassified from held for sale to held for investment, the fair value estimation is based on mortgage-backed securities prices, interest rate risk and an internally developed credit component. Therefore, these loans are classified within Level 3 of the valuation hierarchy. An adverse change in the loss rate or severity assumption would result in a decrease in fair value of the related loan. The Secondary Marketing Department, which reports to the Bancorp's Chief Operating Officer, in conjunction with the Consumer Credit Risk Department, which reports to the Bancorp's Chief Risk Officer, are responsible for determining the valuation methodology for residential mortgage loans held for investment. The Secondary Marketing Department reviews loss severity assumptions quarterly to determine if adjustments are necessary based on decreases in observable housing market data. This group also reviews trades in comparable benchmark securities and adjusts the values of loans as necessary. Consumer Credit Risk is responsible for the credit component of the fair value which is based on internally developed loss rate models that take into account historical loss rates and loss severities based on underlying collateral values.
Derivatives
Exchange-traded derivatives valued using quoted prices and certain over-the-counter derivatives valued using active bids are classified within Level 1 of the valuation hierarchy. Most of the Bancorp's derivative contracts are valued using DCF or other models that incorporate current market interest rates, credit spreads assigned to the derivative counterparties and other market parameters and, therefore, are classified within Level 2 of the valuation hierarchy. Such derivatives include basic and structured interest rate, foreign exchange and commodity, swaps and options. Derivatives that are valued based upon models with significant unobservable market parameters are classified within Level 3 of the valuation hierarchy. At March 31, 2015 and December 31, 2014, derivatives classified as Level 3, which are valued using models containing unobservable inputs, consisted primarily of a warrant associated with the initial sale of the Bancorp's 51% interest in Vantiv Holding, LLC to Advent International and a total return swap associated with the Bancorp's sale of Visa, Inc. Class B shares. Level 3 derivatives also include IRLCs, which utilize internally generated loan closing rate assumptions as a significant unobservable input in the valuation process.
The warrant allows the Bancorp to purchase approximately 20 million incremental nonvoting units in Vantiv Holding, LLC at an exercise price of $15.98 per unit and requires settlement under certain defined conditions involving change of control. The fair value of the warrant is calculated in conjunction with a third party valuation provider by applying Black-Scholes option valuation models using probability weighted scenarios which contain the following inputs: Vantiv, Inc. stock price, strike price per the Warrant Agreement and several unobservable inputs, such as expected term, expected volatility and expected dividend rate.
For the warrant, an increase in the expected term (years) and the expected volatility assumptions would result in an increase in the fair value; conversely, a decrease in these assumptions would result in a decrease in the fair value. The Accounting and Treasury Departments, both of which report to the Bancorp's Chief Financial Officer, determined the valuation methodology for the warrant. Accounting and Treasury review changes in fair value on a quarterly basis for reasonableness based on changes in historical and implied volatilities, expected terms, probability weightings of the related scenarios, and other assumptions.
Under the terms of the total return swap, the Bancorp will make or receive payments based on subsequent changes in the conversion rate of the Visa, Inc. Class B shares into Class A shares. Additionally, the Bancorp will make a quarterly payment based on Visa's stock price and the conversion rate of the Visa, Inc. Class B shares into Class A shares until the date on which the Covered Litigation is settled. The fair value of the total return swap was calculated using a DCF model based on unobservable inputs consisting of management's estimate of the probability of certain litigation scenarios, the timing of the resolution of the Covered Litigation and Visa litigation loss estimates in excess, or shortfall, of the Bancorp's proportional share of escrow funds.
An increase in the loss estimate or a delay in the resolution of the Covered Litigation would result in an increase in fair value; conversely, a decrease in the loss estimate or an acceleration of the resolution of the Covered Litigation would result in a decrease in fair value. The Accounting and Treasury Departments determined the valuation methodology for the total return swap. Accounting and Treasury review the changes in fair value on a quarterly basis for reasonableness based on Visa stock price changes, litigation contingencies, and escrow funding.
The net fair value asset of the IRLCs at March 31, 2015 was $19 million. Immediate decreases in current interest rates of 25 bps and 50 bps would result in increases in the fair value of the IRLCs of approximately $7 million and $14 million, respectively. Immediate increases of current interest rates of 25 bps and 50 bps would result in decreases in the fair value of the IRLCs of approximately $8 million and $16 million, respectively. The decrease in fair value of IRLCs due to immediate 10% and 20% adverse changes in the assumed loan closing rates would be approximately $2 million and $4 million, respectively, and the increase in fair value due to immediate 10% and 20% favorable changes in the assumed loan closing rates would be approximately $2 million and $4 million, respectively. These sensitivities are hypothetical and should be used with caution, as changes in fair value based on a variation in assumptions typically cannot be extrapolated because the relationship of the change in assumptions to the change in fair value may not be linear.
The Consumer Line of Business Finance Department, which reports to the Bancorp's Chief Financial Officer, and the aforementioned Secondary Marketing Department are responsible for determining the valuation methodology for IRLCs. Secondary Marketing, in conjunction with a third party valuation provider, periodically review loan closing rate assumptions and recent loan sales to determine if adjustments are needed for current market conditions not reflected in historical data.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
Certain assets and liabilities are measured at fair value on a nonrecurring basis. These assets and liabilities are not measured at fair value on an ongoing basis; however, they are subject to fair value adjustments in certain circumstances, such as when there is evidence of impairment.
The following tables provide the fair value hierarchy and carrying amount of all assets that were held as of March 31, 2015 and 2014, and for which a nonrecurring fair value adjustment was recorded during the three months ended March 31, 2015 and 2014, and the related gains and losses from fair value adjustments on assets sold during the period as well as assets still held as of the end of the period.

Commercial loans held for sale
During the three months ended March 31, 2015 and 2014, the Bancorp transferred an immaterial amount of commercial loans from the portfolio to loans held for sale that upon transfer were measured at lower of cost or fair value. There were immaterial amounts of fair value adjustments for the three months ended March 31, 2015 and 2014 that were generally based on appraisals of the underlying collateral and were therefore, classified within Level 3 of the valuation hierarchy. Additionally, there were $1 million of fair value adjustments on existing commercial loans held for sale for the three months ended March 31, 2015 and 2014. The fair value adjustments were also based on appraisals of the underlying collateral and were therefore classified within Level 3 of the valuation hierarchy. During the three months ended March 31, 2015 the Bancorp recognized a $5 million gain on sale of certain commercial loans held for sale. There were no gains recognized during the three months ended March 31, 2014. An adverse change in the fair value of the underlying collateral would result in a decrease in the fair value measurement.
The Accounting Department determines the procedures for valuation of commercial HFS loans which may include a comparison to recently executed transactions of similar type loans. A monthly review of the portfolio is performed for reasonableness. Quarterly, appraisals approaching a year-old are updated and the Real Estate Valuation group, which reports to the Chief Risk Officer, in conjunction with the Commercial Line of Business review the third party appraisals for reasonableness. Additionally, the Commercial Line of Business Finance Department, which reports to the Bancorp's Chief Financial Officer, in conjunction with the Accounting Department reviews all loan appraisal values, carrying values and vintages.
Commercial loans held for investment
During the three months ended March 31, 2015 and 2014, the Bancorp recorded nonrecurring impairment adjustments to certain commercial and industrial, commercial mortgage and commercial construction loans held for investment. Larger commercial loans included within aggregate borrower relationship balances exceeding $1 million that exhibit probable or observed credit weaknesses are subject to individual review for impairment. The Bancorp considers the current value of collateral, credit quality of any guarantees, the guarantor's liquidity and willingness to cooperate, the loan structure and other factors when evaluating whether an individual loan is impaired. When the loan is collateral dependent, the fair value of the loan is generally based on the fair value of the underlying collateral supporting the loan and therefore these loans were classified within Level 3 of the valuation hierarchy. In cases where the carrying value exceeds the fair value, an impairment loss is recognized.
An adverse change in the fair value of the underlying collateral would result in a decrease in the fair value measurement. The fair values and recognized impairment losses are reflected in the previous table. Commercial Credit Risk, which reports to the Chief Risk Officer, is responsible for preparing and reviewing the fair value estimates for commercial loans held for investment.
Residential mortgage loans
During the three months ended March 31, 2015, the Bancorp transferred approximately $55 million of restructured residential mortgage loans from held for sale to portfolio as the Bancorp no longer had the intent to sell the loans. Upon transfer, the Bancorp recognized a nonrecurring fair value adjustment of $1 million on these loans, which had previously been transferred to held for sale in the fourth quarter of 2014.
MSRs
Mortgage interest rates decreased during the three months ended March 31, 2015 and the Bancorp recognized temporary impairment in certain classes of the MSR portfolio and the carrying value was adjusted to the fair value. The Bancorp recognized a recovery of temporary impairment on servicing rights during the three months ended March 31, 2014. MSRs do not trade in an active, open market with readily observable prices. While sales of MSRs do occur, the precise terms and conditions typically are not readily available. Accordingly, the Bancorp estimates the fair value of MSRs using internal OAS models with certain unobservable inputs, primarily prepayment speed assumptions, OAS and weighted average lives, resulting in a classification within Level 3 of the valuation hierarchy. Refer to Note 11 for further information on the assumptions used in the valuation of the Bancorp's MSRs. The Secondary Marketing Department and Treasury Department are responsible for determining the valuation methodology for MSRs. Representatives from Secondary Marketing, Treasury, Accounting and Risk Management are responsible for reviewing key assumptions used in the internal OAS model. Two external valuations of the MSR portfolio are obtained from third parties that use valuation models in order to assess the reasonableness of the internal OAS model. Additionally, the Bancorp participates in peer surveys that provide additional confirmation of the reasonableness of key assumptions utilized in the MSR valuation process and the resulting MSR prices.
OREO
During the three months ended March 31, 2015, the Bancorp recorded nonrecurring adjustments to certain commercial and residential real estate properties classified as OREO and measured at the lower of carrying amount or fair value. These nonrecurring losses are primarily due to declines in real estate values of the properties recorded in OREO. For the three months ended March 31, 2015 and 2014, these losses include $5 million and $3 million respectively, recorded as charge-offs, on new OREO properties transferred from loans during the respective periods and $3 million and $10 million, respectively, recorded as negative fair value adjustments on OREO in other noninterest expense and other noninterest income, respectively, subsequent to their transfer from loans. As discussed in the following paragraphs, the fair value amounts are generally based on appraisals of the property values, resulting in a classification within Level 3 of the valuation hierarchy. In cases where the carrying amount exceeds the fair value, less costs to sell, an impairment loss is recognized. The previous tables reflect the fair value measurements of the properties before deducting the estimated costs to sell.
The Real Estate Valuation department, which reports to the Chief Risk Officer, is solely responsible for managing the appraisal process and evaluating the appraisal for all commercial properties transferred to OREO. All appraisals on commercial OREO properties are updated on at least an annual basis.
The Real Estate Valuation department reviews the BPO data and internal market information to determine the initial charge-off on residential real estate loans transferred to OREO. Once the foreclosure process is completed, the Bancorp performs an interior inspection to update the initial fair value of the property. These properties are reviewed at least every 30 days after the initial interior inspections are completed. The Asset Manager receives a monthly status report for each property which includes the number of showings, recently sold properties, current comparable listings and overall market conditions.
Bank premises
The Bancorp monitors consumer preferences for banking interactions and related customer behavior patterns in an effort to ensure that its retail distribution network is both responsive to such trends and efficient. As part of this ongoing assessment, the Bancorp determined that certain components of its bank premises would no longer be held for or used for their intended purposes and therefore these properties were written down to their lower of cost or market value. At least annually thereafter, the Bancorp will review these properties for market fluctuations. The fair value amounts were generally based on appraisals of the property values received from a third party appraiser, resulting in a classification within Level 3 of the valuation hierarchy. Corporate Facilities, which reports to the Chief Strategy and Administrative Officer, in conjunction with Accounting are responsible for preparing and reviewing the fair value estimates for bank premises.
Operating lease equipment
During the three months ended March 31, 2015, the Bancorp recorded nonrecurring impairment adjustments to certain operating lease equipment. When evaluating whether an individual asset is impaired, the Bancorp considers the current fair value of the asset, the changes in overall market demand for the asset and the rate of change in advancements associated with technological improvements that impact the demand for the specific asset under review. As part of this ongoing assessment, the Bancorp determined that the carrying values of certain operating lease equipment were not recoverable and as a result, the Bancorp recorded an impairment loss equal to the amount by which the carrying value of the assets exceeded the fair value. The fair value amounts were generally based on appraised values of the assets, resulting in a classification within Level 3 of the valuation hierarchy. The Commercial Leasing Department, which reports to the Chief Operating Officer, is responsible for preparing and reviewing the fair value estimates for operating lease equipment. Refer to Note 8 for further information on the impairment charge related to certain operating lease equipment.
Fair Value Option
The Bancorp elected to measure certain residential mortgage loans held for sale under the fair value option as allowed under U.S. GAAP. Electing to measure residential mortgage loans held for sale at fair value reduces certain timing differences and better matches changes in the value of these assets with changes in the value of derivatives used as economic hedges for these assets. Management's intent to sell residential mortgage loans classified as held for sale may change over time due to such factors as changes in the overall liquidity in markets or changes in characteristics specific to certain loans held for sale. Consequently, these loans may be reclassified to loans held for investment and maintained in the Bancorp's loan portfolio. In such cases, the loans will continue to be measured at fair value.
Fair value changes recognized in earnings for instruments held at March 31, 2015 and 2014 for which the fair value option was elected as well as the changes in fair value of the underlying IRLCs, included gains of $30 million and $23 million, respectively. These gains are reported in mortgage banking net revenue in the Condensed Consolidated Statements of Income.
Valuation adjustments related to instrument-specific credit risk for residential mortgage loans measured at fair value negatively impacted the fair value of those loans by $1 million and $2 million at March 31, 2015 and December 31, 2014, respectively. Interest on residential mortgage loans measured at fair value is accrued as it is earned using the effective interest method and is reported as interest income in the Condensed Consolidated Statements of Income.
The following tables summarize the difference between the fair value and the principal balance for residential mortgage loans measured at fair value as of:
		Aggregate	Aggregate Unpaid

Cash and due from banks, other securities, other short-term investments, deposits, federal funds purchased and other short-term borrowings
For financial instruments with a short-term or no stated maturity, prevailing market rates and limited credit risk, carrying amounts approximate fair value. Those financial instruments include cash and due from banks, FHLB and FRB restricted stock, other short-term investments, certain deposits (demand, interest checking, savings, money market and foreign office deposits), federal funds purchased, and other short-term borrowings excluding FHLB borrowings. Fair values for other time deposits, certificates of deposit $100,000 and over and FHLB borrowings were estimated using a DCF calculation that applies prevailing LIBOR/swap interest rates and a spread for new issuances with similar terms.
Held-to-maturity securities
The Bancorp's held-to-maturity securities are primarily composed of instruments that provide income tax credits as the economic return on the investment. The fair value of these instruments is estimated based on current U.S. Treasury tax credit rates.
Loans held for sale
Fair values for commercial loans held for sale were valued based on executable bids when available, or on DCF models incorporating appraisals of the underlying collateral, as well as assumptions about investor return requirements and amounts and timing of expected cash flows. Fair values for residential mortgage loans held for sale were valued based on estimated third-party valuations utilizing recent sales data from similar transactions. Broker opinion statements were also obtained as additional evidence to support the third-party valuations. Fair values for other consumer loans held for sale were based on contractual values upon which the loans may be sold to a third party, and approximate their carrying value.
Portfolio loans and leases, net
Fair values were estimated by discounting future cash flows using the current market rates of loans to borrowers with similar credit characteristics, similar remaining maturities, prepayment speeds and loss severities. The Bancorp estimates fair values at the transaction level whenever possible. For certain products with a very large number of homogenous transactions, like residential mortgage loans, the Bancorp employs a pool approach. This approach involves stratifying and sorting the entire population of transactions into a smaller number of pools with like characteristics. Characteristics may include maturity date, coupon, origination date and principal amortization method.
Long-term debt
Fair value of long-term debt was based on quoted market prices, when available, or a DCF calculation using LIBOR/swap interest rates and, in some cases, Fifth Third credit and/or debt instrument spreads for new issuances with similar terms.

Business_Segments

Business Segments	3 Months Ended
	Mar. 31, 2015
Segment Reporting
Business Segments	20. Business Segments
	The Bancorp reports on four business segments: Commercial Banking, Branch Banking, Consumer Lending and Investment Advisors. Results of the Bancorp's business segments are presented based on its management structure and management accounting practices. The structure and accounting practices are specific to the Bancorp; therefore, the financial results of the Bancorp's business segments are not necessarily comparable with similar information for other financial institutions. The Bancorp refines its methodologies from time to time as management's accounting practices and businesses change.
	The Bancorp manages interest rate risk centrally at the corporate level by employing an FTP methodology. This methodology insulates the business segments from interest rate volatility, enabling them to focus on serving customers through loan originations and deposit taking. The FTP system assigns charge rates and credit rates to classes of assets and liabilities, respectively, based on expected duration and the U.S. swap curve. Matching duration allocates interest income and interest expense to each business segment so its resulting net interest income is insulated from interest rate risk. In a rising rate environment, the Bancorp benefits from the widening spread between deposit costs and wholesale funding costs. However, the Bancorp's FTP system credits this benefit to deposit-providing businesses, such as Branch Banking and Investment Advisors, on a duration-adjusted basis. The net impact of the FTP methodology is captured in General Corporate and Other.
	The Bancorp adjusts the FTP charge and credit rates as dictated by changes in interest rates for various interest-earning assets and interest-bearing liabilities and by the review of the estimated durations for the indeterminate-lived deposits. The credit rate provided for demand deposit accounts is reviewed annually based upon the account type, its estimated duration and the corresponding fed funds, U.S. swap curve or swap rate. The credit rates for several deposit products were reset January 1, 2015 to reflect the current market rates and updated market assumptions. These rates were generally lower than those in place during 2014, thus net interest income for deposit providing businesses was negatively impacted during 2015.
	The business segments are charged provision expense based on the actual net charge-offs experienced by the loans and leases owned by each business segment. Provision expense attributable to loan and lease growth and changes in ALLL factors are captured in General Corporate and Other. The financial results of the business segments include allocations for shared services and headquarters expenses. Additionally, the business segments form synergies by taking advantage of cross-sell opportunities and when funding operations, by accessing the capital markets as a collective unit.
	The results of operations and financial position for the three months ended March 31, 2014 were adjusted to reflect the transfer of certain customers and Bancorp employees from Commercial Banking to Branch Banking, effective January 1, 2015. In addition, the prior year balances were adjusted to reflect a change in internal allocation methodology.
	The following is a description of each of the Bancorp's business segments, and the products and services they provide to their respective client bases.

	Nonperforming Assets
	Nonperforming assets include nonaccrual loans and leases for which ultimate collectability of the full amount of the principal and/or interest is uncertain; restructured commercial and credit card loans which have not yet met the requirements to be classified as a performing asset; restructured consumer loans which are 90 days past due based on the restructured terms unless the loan is both well-secured and in the process of collection; and certain other assets, including OREO and other repossessed property. The following table summarizes the Bancorp’s nonperforming loans and leases, by class, as of:

	Excludes $42 and $71 of OREO related to government insured loans at March 31, 2015 and December 31, 2014, respectively. The Bancorp has historically excluded government guaranteed loans classified in OREO from its nonperforming asset disclosures. Upon the prospective adoption on January 1, 2015 of ASU 2014-14 “Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure,” government guaranteed loans meeting certain criteria will be reclassified to other receivables rather than OREO upon foreclosure. As of March 31, 2015, the Bancorp had $21 of government guaranteed loans classified as other receivables. Refer to Note 3 for further information on the adoption of this amended guidance.
