Summary of Significant Accounti

Summary of Significant Accounting and Reporting Policies	12 Months Ended
	Dec. 31, 2017
Basis of Presentation
Summary of Significant Accounting and Reporting Policies	1 . SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES Nature of Operations Fifth Third Bancorp, an Ohio corporation, conducts its principal lending, deposit gathering, transaction processing and service advisory activities through its banking and non-banking subsidiaries from banking centers located throughout the Midwestern and Southeastern regions of the United States. Basis of Presentation The 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 e quity method of accounting and not consolidated. The investments in 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 bala nces among consolidated entities have been eliminated. Use of Estimates 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. Cash and Due From Banks Cash and due from banks consist of currency and coin, cash items in the process of collection and due from banks. Currency and coin includes both U.S. and f oreign currency owned and held at Fifth Third offices and that is in-transit to the FRB. Cash items in the process of collection include checks and drafts that are drawn on another depository institution or the FRB that are payable immediately upon present ation in the U.S. Balances due from banks include noninterest-bearing balances that are funds on deposit at other depository institutions or the FRB. Securities Securities are classified as held-to-maturity, available-for-sale or trading on the date of pu rchase. Only those securities which management has the intent and ability to hold to maturity are classified as held-to-maturity and reported at amortized cost. Securities are classified as available-for-sale when, in management’s judgment, they may be sol d in response to, or in anticipation of, changes in market conditions. Securities are classified as trading when bought and held principally for the purpose of selling them in the near term. Available-for-sale securities are reported at fair value with unr ealized gains and losses, net of related deferred income taxes, included in OCI. Trading securities are reported at fair value with unrealized gains and losses included in noninterest income. The fair value of a security is determined based on quoted marke t prices. If quoted market prices are not available, fair value is determined based on quoted prices of similar instruments or DCF models that incorporate market inputs and assumptions including discount rates, prepayment speeds and loss rates. Realized se curities gains or losses are reported within noninterest income in the Consolidated Statements of Income. The cost of securities sold is based on the specific identification method. Available-for-sale and held-to-maturity securities with unrealized losses are reviewed quarterly for possible OTTI. For debt securities, if the Bancorp intends to sell the debt security or will more likely than not be required to sell the debt security before recovery of the entire amortized cost basis, then an OTTI has occurred . However, even if the Bancorp does not intend to sell the debt security and will not likely be required to sell the debt security before recovery of its entire amortized cost basis, the Bancorp must evaluate expected cash flows to be received and determin e if a credit loss has occurred. In the event of a credit loss, the credit component of the impairment is recognized within noninterest income and the non-credit component is recognized through OCI. For equity securities, the Bancorp’s management evaluates the securities in an unrealized loss position in the available-for-sale portfolio for OTTI on the basis of the duration of the decline in value of the security and severity of that decline as well as the Bancorp’s intent and ability to hold these securiti es for a period of time sufficient to allow for any anticipated recovery in the market value. If it is determined that the impairment on an equity security is other-than-temporary, an impairment loss equal to the difference between the amortized cost of th e security and its fair value is recognized within noninterest income. Portfolio Loans and Leases Basis of a ccounting Portfolio loans and leases are generally reported at the principal amount outstanding, net of unearned income, deferred direct loan origination fees and costs and any direct principal charge-offs. Direct loan origination fees and costs are deferred and the net amount is amortized over the estimated life of the related loans as a yield adjustment. Interest income is recognized based on the principal balance outstanding computed using the effective interest method. Loans acquired by the Bancorp through a purchase business combination are recorded at fair value as of the acquisition date. The Bancorp does not carry over the acquired compan y’s ALLL, nor does the Bancorp add to its existing ALLL as part of purchase accounting. Purchased loans are evaluated for evidence of credit deterioration at acquisition and recorded at their initial fair value. For loans acquired with no evidence of credi t deterioration, the fair value discount or premium is amortized over the contractual life of the loan as an adjustment to yield. For loans acquired with evidence of credit deterioration, the Bancorp determines at the acquisition date the excess of the loa n’s contractually required payments over all cash flows expected to be collected as an amount that should not be accreted into interest income (nonaccretable difference). The remaining amount representing the difference in the expected cash flows of acquir ed loans and the initial investment in the acquired loans is accreted into interest income over the remaining life of the loan or pool of loans (accretable yield). Subsequent to the acquisition date, increases in expected cash flows over those expected at the acquisition date are recognized prospectively as interest income over the remaining life of the loan. The present value of any decreases in expected cash flows resulting directly from a change in the contractual interest rate are recognized prospective ly as a reduction of the accretable yield. The present value of any decreases in expected cash flows after the acquisition date as a result of credit deterioration is recognized by recording an ALLL or a direct charge-off. Subsequent to the acquisition dat e, the methods utilized to estimate the required ALLL are similar to originated loans. This method of accounting for loans acquired with deteriorated cr edit quality does not apply to loans carried at fair value, residential mortgage loans held for sale and loans un der revolving credit agreements. The Bancorp’s lease portfolio consists of both direct financing and leveraged leases. Direct financing leases are carried at the aggregate of lease payments plus estimated residual value of the leased property, les s unearned income. Interest income on direct financing leases is recognized over the term of the lease to achieve a constant periodic rate of return on the outstanding investment. Leveraged leases are carried at the aggregate of lease payments (less nonrec ourse debt payments) plus estimated residual value of the leased property, less unearned income. Interest income on leveraged leases is recognized over the term of the lease to achieve a constant rate of return on the outstanding investment in the lease, n et of the related deferred income tax liability, in the years in which the net investment is positive. Nonaccrual loans and l eases When a loan is placed on nonaccrual status, the accrual of interest, amortization of loan premium, accretion of loan discount and amortization/accretion of deferred net direct loan origination fees or costs are discontinued and all previously accrued and u npaid interest is charged against income. Commercial loans are placed on nonaccrual status when there is a clear indication that the borrower’s cash flows may not be sufficient to meet payments as they become due. Such loans are also placed on nonaccrual s tatus when the principal or interest is past due 90 days or more, unless the loan is both well-secured and in the process of collection. The Bancorp classifies residential mortgage loans that have principal and interest payments that have become past due 1 50 days as nonaccrual unless the loan is both well-secured and in the process of collection. Residential mortgage loans may stay on non accrual status for an extended time as the foreclosure process typically lasts longer than 180 days. Home equity loans an d lines of credit are reported on nonaccrual status if principal or interest has been in default for 90 days or more unless the loan is both well-secured and in the process of collection. Home equity loans and lines of credit that have been in default for 60 days or more are also reported on nonaccrual status if the senior lien has been in default 120 days or more, unless the loan is both well secured and in the process of collection. Residential mortgage, home equity, automobile and other consumer loans an d leases that have been modified in a TDR and subsequently become past due 90 days are placed on nonaccrual status unless the loan is both well-secured and in the process of collection. Commercial and credit card loans that have been modified in a TDR are classified as nonaccrual unless such loans have sustained repayment performance of six months or more and are reasonably assured of repayment in accordance with the restructured terms. Well-secured loans are collateralized by perfected security interests i n real and/or personal property for which the Bancorp estimates proceeds from the sale would be sufficient to recover the outstanding principal and accrued interest balance of the loan and pay all costs to sell the collateral. The Bancorp considers a loan in the process of collection if collection efforts or legal action is proceeding and the Bancorp expects to collect funds sufficient to bring the loan current or recover the entire outstanding principal and accrued interest balance. Nonaccrual commercial l oans and nonaccrual credit card loans are generally accounted for on the cost recovery method. The Bancorp believes the cost recovery method is appropriate for nonaccrual commercial loans and nonaccrual credit card loans because the assessment of collectab ility of the remaining recorded investment of these loans involves a high degree of subjectivity and uncertainty due to the nature or absence of underlying collateral. Under the cost recovery method, any payments received are applied to reduce principal. O nce the entire recorded investment is collected, additional payments received are treated as recoveries of amounts previously charged-off until recovered in full, and any subsequent payments are treated as interest income. Nonaccrual residential mortgage l oans and other nonaccrual consumer loans are generally accounted for on the cash basis method. The Bancorp believes the cash basis method is appropriate for nonaccrual residential mortgage and other nonaccrual consumer loans because such loans have general ly been written down to estimated collateral values and the collectability of the remaining investment involves only an assessment of the fair value of the underlying collateral, which can be measured more objectively with a lesser degree of uncertainty th an assessments of typical commercial loan collateral. Under the cash basis method, interest income is recognized when cash is received, to the extent such income would have been accrued on the loan’s remaining balance at the contractual rate. Nonaccrual lo ans may be returned to accrual status when all delinquent interest and principal payments become current in accordance with the loan agreement and are reasonably assured of repayment in accordance with the contractual terms of the loan agreement, or when t he loan is both well-secured and in the process of collection. Commercial loans on nonaccrual status, including those modified in a TDR, as well as criticized commercial loans with aggregate borrower relationships exceeding $1 million, are subject to an in dividual review to identify charge-offs. The Bancorp does not have an established delinquency threshold for partially or fully charging off commercial loans. Residential mortgage loans, home equity loans and lines of credit and credit card loans that have principal and interest payments that have become past due 180 days are assessed for a charge-off to the ALLL, unless such loans are both well-secured and in the process of collection. Home equity loans and lines of credit are also assessed for charge-off t o the ALLL when such loans or lines of credit have become past due 120 days if the senior lien is also 120 days past due, unless such loans are both well-secured and in the process of collection. Automobile and other consumer loans and leases that have pri ncipal and interest payments that have become past due 120 days are assessed for a charge-off to the ALLL, unless such loans are both well-secured and in the process of collection. Restructured loans and l eases A loan is accounted for as a TDR if the Banc orp, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. A TDR typically involves a modification of terms such as a reduction of the stated interest rate or remaining principal amount of the loan, a reduction of accrued interest or an extension of the maturity date at a stated interest rate lower than the current market rate for a new loan with similar risk. In 2012, the OCC, a national bank regulatory agen cy, issued interpretive guidance that requires non-reaffirmed loans included in Chapter 7 bankruptcy filings to be accounted for as nonperforming TDRs and collateral dependent loans regardless of their payment history and capacity to pay in the future. The Bancorp’s banking subsidiary is a state chartered bank which therefore is not subject to guidance of the OCC. The Bancorp does not consider the bankruptcy court’s discharge of the borrower’s debt a concession when the discharged debt is not reaffirmed and as such, these loans are classified as TDRs only if one or more of the previously mentioned concessions are granted. The Bancorp measures the impairment loss of a TDR based on the difference between the original loan’s carrying amount and the present valu e of expected future cash flows discounted at the original, effective yield of the loan. Residential mortgage loans, home equity loans, automobile loans and other consumer loans modified as part of a TDR are maintained on accrual status, provided there is reasonable assurance of repayment and of performance according to the modified terms based upon a current, well-documented credit evaluation. Commercial loans and credit card loans modified as part of a TDR are maintained on accrual status provided there i s a sustained payment history of six months or more prior to the modification in accordance with the modified terms and collectability is reasonably assured for all remaining contractual pa yments under the modified terms . TDRs of commercial loans and credi t cards that do not have a sustained payment history of six months or more in accordance with their modified terms remain on nonaccrual status until a six month payment history is sustained. In certain cases, commercial TDRs on nonaccrual status may be acc ounted for using the cash basis method for income recognition, provided that full repayment of principal under the modified terms of the loan is reasonably assured. Impaired loans and l eases A loan is considered to be impaired when, based on current infor mation and events, it is probable that the Bancorp will be unable to collect all amounts due (including both principal and interest) according to the contractual terms of the loan agreement. Impaired loans generally consist of nonaccrual loans and leases, loans modified in a TDR and loans over $ 1 million that are currently on accrual status and not yet modified in a TDR, but for which the Bancorp has determined that it is probable that it will grant a payment concession in the near term due to the borrower’ s financial difficulties. For loans modified in a TDR, the contractual terms of the loan agreement refer to the terms specified in the original loan agreement. A loan restructured in a TDR is no longer considered impaired in years after the restructuring i f the restructuring agreement specifies a rate equal to or greater than the rate the Bancorp was willing to accept at the time of the restructuring for a new loan with comparable risk and the loan is not impaired based on the terms specified by the restruc turing agreement. Refer to the ALLL section for discussion regarding the Bancorp’s methodology for identifying impaired loans and determination of the need for a loss accrual. Loans and Leases Held for Sale Loans and leases held for sale primarily represent conforming fixed-rate residential mortgage loans originated or acquired with the intent to sell in the secondary market and jumbo residential mortgage loans, commercial loans, other residential mortgage loans and other consumer loans that managem ent has the intent to sell. Loans and leases held for sale may be carried at the lower of cost or fair value, or carried at fair value where the Bancorp has elected the fair value option of accounting under U.S. GAAP. The Bancorp has elected to measure cer tain groups of loans held for sale under the fair value option, including certain residential mortgage loans originated as held for sale and certain purchased commercial loans designated as held for sale at acquisition . For loans in which the Bancorp has n ot elected the fair value option, the lower of cost or fair value is determined at the individual loan level. The fair value of residential mortgage loans held for sale for which the fair value election has been made 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 portfo lio composition includes the effects 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. These fair value marks are recorded as a component of nonin terest income in mortgage banking net revenue. The Bancorp generally has commitments to sell residential mortgage loans held for sale in the secondary market. Gains or losses on sales are recognized in mortgage banking net revenue. Management’s intent to s ell 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 recla ssified to loans held for investment and, thereafter, reported within the Bancorp’s residential mortgage class of portfolio loans and leases. In such cases, the residential mortgage loans will continue to be measured at fair value, which is based on mortga ge-backed securities prices, interest rate risk and an internally developed credit component. Loans and leases held for sale are placed on nonaccrual status consistent with the Bancorp’s nonaccrual policy for portfolio loans and leases. Other Real Estate Owned OREO, which is included in other assets, represents property acquired through foreclosure or other proceedings and is carried at the lower of cost or fair value, less costs to sell. All OREO property is periodically evaluated for impairment and decre ases in carrying value are recognized as reductions in other noninterest income in the Consolidated Statements of Income. For government-guaranteed mortgage loans, upon foreclosure, a separate other receivable is recognized if certain conditions are met fo r the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. This receivable is also included in other assets, separate from OREO, in the Consolidated Balance Sheets. ALLL The Bancorp disaggregates its portfolio l oans and leases into portfolio segments for purposes of determining the ALLL. The Bancorp’s portfolio segments include commercial, residential mortgage and consumer. The Bancorp further disaggregates its portfolio segments into classes for purposes of moni toring and assessing credit quality based on certain risk characteristics. Classes within the commercial portfolio segment include commercial and industrial, commercial mortgage owner-occupied, commercial mortgage nonowner-occupied, commercial construction and commercial leasing. The residential mortgage portfolio segment is also considered a class. Classes within the consumer portfolio segment include home equity, automobile, credit card and other consumer loans and leases. For an analysis of the Bancorp’s ALLL by portfolio segment and credit quality information by class, refer to Note 6 . The Bancorp maintains the ALLL to absorb probable loan and lease losses inherent in its portfolio segments. The ALLL is maintained at a level the Bancorp considers to be adequate and is based on ongoing quarterly assessments and evaluations of the collectability and historical loss experience of loans and leases. Credit losses are charged and recoveries are credited to the ALLL. Provisions for loan and lease losses are based on the Bancorp’s review of the historical credit loss experience and such factors that, in management’s judgment, deserve consideration under existing economic conditions in estimating probable credit losses. The Bancorp’s strategy for credit risk ma nagement includes a combination of conservative exposure limits significantly below legal lending limits and conservative underwriting, documentation and collections standards. The strategy also emphasizes diversification on a geographic, industry and cust omer level, regular credit examinations and quarterly management reviews of large credit exposures and loans experiencing deterioration of credit quality. The Bancorp’s methodology for determining the ALLL is based on historical loss rates, current credit grades, specific allocation on loans modified in a TDR and impaired commercial credits above specified thresholds and other qualitative adjustments. Allowances on individual commercial loans, TDRs and historical loss rates are reviewed quarterly and adjust ed as necessary based on changing borrower and/or collateral conditions and actual collection and charge-off experience. An unallocated allowance is maintained to recognize the imprecision in estimating and measuring losses when evaluating allowances for p ools of loans. Larger commercial loans included within aggregate borrower relationship balances exceeding $ 1 million that exhibit probable or observed credit weaknesses, as well as loans that have been modified in a TDR, 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 individua l loan is impaired. Other factors may include the industry and geographic region 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. When individua l loans are impaired, allowances are determined based on management’s estimate of the borrower’s ability to repay the loan given the availability of collateral and other sources of cash flow, as well as an evaluation of legal options available to the Banco rp. Allowances for impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, fair value of the underlying collateral or readily observable secondary market values. The Bancorp eva luates the collectability of both principal and interest when assessing the need for a loss accrual. Historical credit loss rates are applied to commercial loans that are not impaired or are impaired, but smaller than the established threshold of $ 1 millio n and thus not subject to specific allowance allocations. The loss rates are derived from migration analyses for several portfolio stratifications, which track the historical net charge-off experience sustained on loans according to their internal risk gra de. The risk grading system utilized for allowance analysis purposes encompasses ten categories. Homogenous loans and leases in the residential mortgage and consumer portfolio segments are not individually risk graded. Rather, standard credit scoring syst ems and delinquency monitoring are used to assess credit risks and allowances are established based on the expected net charge-offs. Loss rates are based on the trailing twelve month net charge-off history by loan category. Historical loss rates may be adj usted for certain prescriptive and qualitative factors that, in management’s judgment, are necessary to reflect losses inherent in the portfolio. The prescriptive loss rate factors include adjustments for delinquency trends, LTV trends and refreshed FICO s core trends. The Bancorp also considers qualitative factors in determining the ALLL. These include adjustments for changes in policies or procedures in underwriting, monitoring or collections, economic conditions, portfolio mix, lending and risk management personnel, results of internal audit and quality control reviews, collateral values and geographic concentrations. The Bancorp considers home price index trends when determining the collateral value qualitative factor. The Bancorp’s primary market areas for lending are the Midw estern and Southeastern regions of the U .S. When evaluating the adequacy of allowances, consideration is given to these regional geographic concentrations and the closely associated effect changing economic conditions have on the Ba ncorp’s customers. In the current year, the Bancorp has not substantively changed any material aspect to its overall approach to determining its ALLL for any of its portfolio segments. There have been no material changes in criteria or estimation technique s as compared to prior periods that impacted the determination of the current period ALLL for any of the Bancorp’s portfolio segments. Reserve for Unfunded Commitments The reserve for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded credit facilities and is included in other liabilities in the Consolidated Balance Sheets. The determination of the adequacy of the reserve is based upon an evaluation of the unfunded c redit facilities, including an assessment of historical commitment utilization experience, credit risk grading and historical loss rates based on credit grade migration. This process takes into consideration the same risk elements that are analyzed in the determination of the adequacy of the Bancorp’s ALLL, as previously discussed. Net adjustments to the reserve for unfunded commitments are included in other noninterest expense in the Consolidated Statements of Income. Loan Sales and Securitizations The Bancorp periodically sells loans through either securitizations or individual loan sales in accordance with its investment policies. The sold loans are removed from the Consolidated Balance S heet and a net gain or loss is recognized in the Consolidated Financial Statements at the time of sale. The Bancorp typically isolates the loans through the use of a VIE and thus is required to assess whether the entity holding the sold or securitized loans is a VIE and whether the Bancorp is the primary beneficiary and therefore consolidator of that VIE. If the Bancorp holds the power to direct activities most significant to the economic performance of the VIE and has the obligation to absorb losses or right to receive benefits that could potentially be significant to the VIE, then the Bancorp will generally be deemed the primary beneficiary of the VIE. 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 t he equity method of accounting or other accounting standards as appropriate. Refer to Note 11 for further information on consolidated and non-consolidated VIEs. The Bancorp’s loan sales and securitizations are generally structured with servicing r etaine d, which often results in the recording of servicing rights. The Bancorp may also purchase servicing rights. Effective January 1, 2017, the Bancorp elected to prospectively adopt the fair value method for all existing classes of its residential mortgage se rvicing rights portfolio. Upon this election, all servicing rights are measured at fair value at each reporting date and changes in the fair value of servicing rights are reported in mortgage banking net revenue in the Consolidated Statements of Income in the period in which the changes occur. The election of the fair value method did not require a cumulative effect adjustment to retained earnings as there was no difference between the carrying value of the servicing rights, net of valuation allowance, and the fair value. Servicing rights are valued using internal OAS models. Key economic assumptions used in estimating the fair value of the servicing rights include the prepayment speeds of the underlying loans, the weighted-average life, the OAS spread and t he weighted-average coupon rate, as applicable. The primary risk of material changes to the value of the servicing rights resides in the potential volatility in the economic assumptions used, particularly the prepayment speeds. In order to assist in the as sessment of the fair value of servicing rights, the Bancorp obtains external valuations of the servicing rights portfolio from third parties and participates in peer surveys that provide additional confirmation of the reasonableness of the key assumptions utilized in the internal OAS model. Prior to the election of the fair value method, servicing rights were initially recorded at fair value and subsequently amortized in proportion to, and over the period of, estimated net servicing revenue. Servicing right s were tested for impairment monthly, based on fair value, with temporary impairment recognized through a valuation allowance and other-than-temporary impairment recognized through a write-off of the servicing asset and related valuation allowance. Amortiz ation and provisions for impairment of servicing rights were recorded as a component of mortgage banking net revenue in the Consolidated Statements of Income. Fees received for servicing loans owned by investors are based on a percentage of the outstandin g monthly principal balance of such loans and are included in noninterest income in the Consolidated Statements of Income as loan payments are received. Costs of servicing loans are charged to expense as incurred. Reserve for Representation and Warranty P rovisions 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 gen eral, 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 m a

Restriction On Cash
Restriction on Cash, Dividends and Other Capital Actions	3 . RESTRICTIONS ON CASH, DIVIDENDS AND OTHER CAPITAL ACTIONS Reserve Requirement The FRB, under Regulation D, requires that banks hold cash in reserve against deposit liabilities when total reservable deposit liabilities are greater than the regulatory exemption , kn own as the reserve requirement. The reserve requirement is calculated based on a two-week average of daily net transaction account deposits as defined by the FRB and may be satisfied with average vault cash during the following two-week maintenance period . When vault cash is not suffici ent to meet the reserve requirement, the remaining amount must be satisfied with average funds held at the FRB. At December 31, 2017 and 2016 , th e Bancorp’s banking subsidiary reserve requirement was $ 1. 5 billion and $ 1. 6 billion, respectively. Addit ionally, the Bancorp’s banking subsidiary average reserve requirement was $ 1.4 b illion and $ 1. 6 billion in 2017 and 2016 , respectively. Restrictions on Cash Dividends The principal source of income and funds for the Bancorp (parent company) are divi dends from its subsidiaries. The dividends paid by the Bancorp’s banking subsidiary are subject to regulations and limitations prescribed by state and federal supervisory agencies. The Bancorp’s banking subsidiary paid the Bancorp’s nonbank subsidiary hold ing company , which in turn paid the Bancorp $ 2.3 billion and $ 1.9 b illion in dividends during the years ended December 31, 2017 and 2016 , respectively. The Bancorp’s nonbank-subsidiaries are also limited by certain federal and state statutory provisi ons and regulations covering the amount of dividends that may be paid in any given year. Capital Actions In 2011, the FRB adopted the capital plan rule, which requires BHCs with consolidated assets of $ 50 billion or more to submit annual capital plans to the FRB for review. Under the rule, these capital plans must include detailed descriptions of the following: the BHC’s internal processes for assessing capital adequacy; the policies governing capital actions such as common stock issuances, dividends and s hare repurchases; and all planned capital actions over a nine-quarter planning horizon. Further, each BHC must also report to the FRB the results of stress tests conducted by the BHC under a number of scenarios that assess the sources and uses of capital u nder baseline and stressed economic scenarios. The FRB launched the 2017 stress testing program and CCAR on February 3, 2017 , with submissions of stress te st results and capital plans to the FRB due on April 5, 2017 , which the Bancorp submitted as required. The FRB’s review of the capital plan assessed the comprehensiveness of the capital plan, the reasonableness of the assumptions and the analysis underlying the capital plan. Additionally, the FRB reviewed the robustness of the capital adequacy pro cess, the capital policy and the Bancorp’s ability to maintain capital above each minimum regulatory capital ratio on a pro forma basis under expected and stressful conditions throughout the planning horizon. On June 28, 2017, the Bancorp announced the re sults of its capital plan submitted to the FRB as part of the 2017 CCAR. For BHCs that proposed capital distributions in their plans, the FRB either objected to the plan or provided a non-objection whereby the FRB permitted the proposed capital distributio ns. The FRB indicated to the Bancorp that it did not object to the following capital actions for the period beginning July 1, 2017 and ending June 30, 2018: The increase in the quarterly common stock dividend to $0.16 from $0.14 beginning in the third quar ter of 2017 and to $0.18 beginning in the second quarter of 2018 ; The repurchase of common shares in an amount up to $ 1.161 billion, or a 76% increase over the 2016 capital plan. These repurchases include $ 88 million in repurchases related to share issuan ces under employee benefit plans and $ 48 million in repurchases related to previously-recognized TRA transaction after-tax gains; The additional ability to repurchase common shares in the amount of any after-tax capital generated from the sale of Vantiv, Inc. common stock; The additional ability to repurchase common shares in the amount of any after-tax cash income generated from the termination and settlement of gross cash flows from existing TRAs with Vantiv, Inc. or potential future TRAs that may be generated from additional sales of Vantiv, Inc. The Bancorp recognized a gain on sale of Vantiv, Inc. shares of $ 1.0 billion during the year ended December 31, 2017 and also entered into accelerated share repurchase transactions during the years ended December 31, 2017 and 2016 . For more information related to these transactions, refer to Note 19 and Note 23 . In the third quarter of 2017, the Bancorp increased the quarterly common stock dividend to $ 0.16 .

Refer to Note 11 for further discussion on the deconsolidation of a VIE associated with these loans in the third quarter of 2017. C REDIT RISK PROFILE Commercial Portfolio Segment For purposes of analyzing historical loss rates used in the determination of the ALLL and 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 non owner- occupied, commerc ial construction and commercial leas es . 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 and loss. The five categories, which are derived from standard regulatory rating definitions, are assigned upon initial approval of credit to borr owers 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 ba sed 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 potent ial 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 doubtf ul 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 questionab le 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 estima ted 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 cl assified as loss are considere d uncollectible and are charged- off in the period in which they are determined to be uncollectible. Because loans and leases in this category are ful ly 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 December 31, 2017 ($ in millions) Pass Mention Substandard Doubtful Total Commercial and industrial loans $ 38,813 1,115 1,235 7 41,170 Commercial mortgage owner-occupied loans 3,207 75 80 - 3,362 Commercial mortgage nonowner-occupied loans 3,117 28 97 - 3,242 Commercial construction loans 4,553 - - - 4,553 Commercial leases 3,922 72 74 - 4,068 Total commercial loans and leases $ 53,612 1,290 1,486 7 56,395 Special As of December 31, 2016 ($ in millions) Pass Mention Substandard Doubtful Total Commercial and industrial loans $ 38,844 1,204 1,604 24 41,676 Commercial mortgage owner-occupied loans 3,168 72 117 3 3,360 Commercial mortgage nonowner-occupied loans 3,466 4 69 - 3,539 Commercial construction loans 3,902 1 - - 3,903 Commercial leases 3,894 54 26 - 3,974 Total commercial loans and leases $ 53,274 1,335 1,816 27 56,452 Residential Mortgage and Consumer Portfolio Segments 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 nonper forming status is presented in the following table . Refer to the nonaccrual loans and leases section of Note 1 for additional delinquenc y and nonperforming information .

Impaired Portfolio 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 individu al 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.

Excludes $ 19 of restructured nonaccrua l loans at December 31, 2016 associated with a consolidated VIE in which the Bancorp had no continuing credit risk due the risk being assumed by a third party. Refer to Note 11 for further discussion on the deconsolidation of the VIE associated with these loans in the third quarte 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 $ 235 million and $ 260 million as of December 31, 2017 and 2016 , respectively. 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 amount s 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 o f the loan’s maturity date 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 measur e the ALLL for a loan prior to modification, and whether any charge-offs were recorded on the loan before o r at the time of modification. Ref er to the ALLL section of Note 1 for information on the Bancorp’s ALLL methodology. Upon modification of a loa n , the Bancorp measures the related imp airment as the difference between the estimated future cash fl ows 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 resultin g measurement may result in the need for minimal or no 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 i nterest, that amount is charged- off to the ALLL. The Bancorp had commitments to lend additional funds to borrowers whose terms have been m odified in a TDR, consisting of line of credit and letter of credit commitments of $ 53 million and $ 78 million, respectively, as of December 31, 2017 compared with $ 82 million and $ 57 million, respectively, as of December 31, 2016 .

Represents number of loans post-modification and excludes loans previously modified in a TDR. 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 consum er 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, auto mobile 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 a s a charge-off or an increase in ALLL. The Bancorp recognizes ALLL for the entire balance of the credit card loans modified in a TDR that subsequently default . The following tables provide a summary of TDRs that subsequently defaulted during the years ended December 31, 2017, 2016 and 2015 and were within twelve months of the restructuring date: Number of Recorded December 31, 2017 ($ in millions) (a) Contracts Investment Commercial loans: Commercial and industrial loans 7 $ 17 Commercial mortgage owner-occupied loans 4 1 Residential mortgage loans 172 24 Consumer loans: Home equity 16 2 Credit card 1,633 8 Total portfolio loans 1,832 $ 52 (a) Excludes all loans and leases held for sale and loans acquired with deteriorated credit quality.

Depreciation and amortization expense related to bank premises and equipment was $ 234 million, $ 2 42 million and $ 2 56 million for the years ended December 31, 2017 , 2016 and 2015 , respectively . The Bancorp monitors changing customer preferences associated with the channels it uses for banking transacti ons to evaluate the efficiency, competitiveness and quality of the customer service experience in its consumer distribution network. As part of this ongoing assessment, the Bancorp may determine tha t 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 lan d which had previously been held for future branch expansion. The Bancorp performs assessments of the recoverability of long-lived assets when events or changes in circumstances indicate that their carrying values may not be recoverable . Impairment losses associated with such assessments and lower of cost or market adjustments were $ 7 million , $ 32 million and $ 109 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. The recognized impairment losses were recorded in other no ninterest income in the Consolidated Statements of Income. Gross occupancy expense for cancelable and noncancelable leases, which is included in net occupancy expense in the Consolidated Statements of Income , was $ 1 01 million , $ 100 million and $ 110 million for the years ended December 31, 2017 , 2016 and 2015 , respectively, which was reduced by rental income from leased premises of $ 1 3 million , $ 16 million and $ 18 million during the years ended December 31, 2017 , 2016 and 2015 , respectively.

Goodwill
Goodwill	9 . GOODWILL Business combinations entered into by the Bancorp typically include the acquisition of goodwill. Acquisition activity includes acquis itions in the respective period in addition to purchase accounting adjustments related to previous acquisitions , if any . The Bancorp completed its annual goodwill impairment test as of September 30, 2017 by performing a qualitative assessment of goodwill at the reporting unit level to determine whether any indicators of impairment existed. In performing this qualitative asses sment, the Bancorp evaluated events and circumstances since the last impairment analysis, macroeconomic conditions, banking industry and market conditions and key financial metrics of the Bancorp as well as reporting unit and overall Bancorp financial perf ormance. After assessing the totality of the events and circumstances, the Bancorp determined that it was not more likely than not that the fair values of the Commercial Banking, Branch Banking and Wealth and Asset Management reporting units were less than their respective carrying amounts and, therefore, the first and second steps of the quantitative goodwill impairment test were deemed unnecessary . Changes in the net carrying amount of goodwill, by reporting unit, for the years ended December 31, 2017 and 2016 were as follows: Commercial Branch Consumer Wealth and Asset ($ in millions) Banking Banking Lending Management Total Goodwill $ 1,363 1,655 215 148 3,381 Accumulated impairment losses (750) - (215) - (965) Net carrying amount as of December 31, 2015 $ 613 1,655 - 148 2,416 Acquisition activity - - - - - Net carrying amount as of December 31, 2016 $ 613 1,655 - 148 2,416 Acquisition activity - - - 29 29 Net carrying amount as of December 31, 2017 $ 613 1,655 - 177 2,445

Variable Interest Entities
Variable Interest Entities	11 . 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 equ ity at risk to finance their activities without additional subordinated financial support or the equity investors of the entities as a group lack any of the characteri stics of a controlling interest . The Bancorp evaluates its interest 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 require s a reconsideration. If the Bancorp is determined to be the primary beneficiary of a VI E, 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 accountin g or other accou nting standards as appropriate. Consolidated VIEs The following tables provide a summary of the classifications of consolidated VIE assets, liabilities and noncontrolling interests included in the Consolidated Balance Sheets as of: Automobile Loan CDC December 31, 2017 ($ in millions) Securitizations Investments Total Assets: Other short-term investments $ 62 - 62 Commercial mortgage loans - 20 20 Automobile loans 1,277 - 1,277 ALLL (6) - (6) Other assets 7 - 7 Total assets $ 1,340 20 1,360 Liabilities: Other liabilities $ 2 - 2 Long-term debt 1,190 - 1,190 Total liabilities $ 1,192 - 1,192 Noncontrolling interests $ - 20 20 Automobile Loan CDC December 31, 2016 ($ in millions) Securitizations Investments Total Assets: Cash and due from banks $ 84 1 85 Commercial mortgage loans - 46 46 Automobile loans 1,170 - 1,170 ALLL (6) (20) (26) Other assets 9 - 9 Total assets $ 1,257 27 1,284 Liabilities: Other liabilities $ 3 - 3 Long-term debt 1,094 - 1,094 Total liabilities $ 1,097 - 1,097 Noncontrolling interests $ - 27 27 Automobile l oan s ecuritization s In a securitization transaction that occurred in September of 2017, the Bancorp transferred an aggregate amount of $ 1.1 billion in consumer automobile loans to a bankruptcy remote trust which was deemed to be a VIE. This trust then subsequently issued approximately $ 1.0 billion of asset-backed notes, of which approximately $ 261 million were retained by the Bancorp. Refer to Note 16 for further information. Additionally, in prior years the Bancorp completed securitizatio n transactions in which the Bancorp transferred certain consumer automobile loans to bankruptcy remote trusts which were also deemed to be VIEs. The primary purposes of the VIEs were to issue asset-backed securities with varying levels of credit subordinat ion 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 rec eive 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 t he economic performance of the VIEs. As a result, the Bancorp concluded that it is the primary beneficiary of the VIEs and has consolidated these VIEs. Th e assets of the VIEs are restricted to the settlement of the asset-backed securities and other obligat ions of the VIEs. Third-party holders of the notes do not have recourse to the general assets of the Bancorp. T he economic performance of the VIE s is most significantly impacted by the performance of the underlying loans. The principal risks to which th e VIE s 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 classe s of asset-backed securities to other classes. CDC i nvestment s 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 a s limited par tnerships 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. The Bancorp’s subsidiaries serve as the managing member of certain LLCs invested in business revitalization projects and h ave the right to make decisions that most significantly impact the economic performance of the LLCs. Additionally, the investor members do not own substantive kick-out rights or substantive participating rights over the managing member. The Bancorp has pro vided an indemnification guarante e to the investor member of these LLC s 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 con solidated these VIE s . As a result, the investor members’ interests in these VIE s are presented as noncontrolling interest s in the Consolidated Financial Statements. This presentation includes reporting separately the equity attributable to the noncontrolli ng interest s in the Consolidated Balance Sheets and Consolidated Statements of Changes in Equity and reporting separately the comprehensive income attributable to the noncontrolling interests in the Consolidated Statements of Comprehensive Income and the n et income attributable to the noncontrolling interest s in the Con solidated Statements of Income. During the third quarter of 2017, the Bancorp’s indemnification guarantee for one of the CDC investments for which a Bancorp subsidiary served as the managing member expired and the Bancorp transferred its remaining ownership interest in the VIE to the investor member thus removing the Bancorp from future operations of the VIE. As a result, the Bancorp deconsolidated the VIE during the third quarter of 2017 resu lting in a decrease of $ 27 million in commercial mortgage loans, a decrease of $ 20 million in ALLL associated with the commercial mortgage loans and a decrease of $ 18 million in indemnification guarantee exposure. The Bancorp’s maximum exposure related to these indemnifications at December 31, 2017 and 2016 was $ 17 million and $ 31 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 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 December 31, 2017 ($ in millions) Assets Liabilities Exposure CDC investments $ 1,376 355 1,376 Private equity investments 102 - 150 Loans provided to VIEs 1,845 - 2,910 Total Total Maximum December 31, 2016 ($ in millions) Assets Liabilities Exposure CDC investments $ 1,421 357 1,421 Private equity investments 176 - 232 Loans provided to VIEs 1,735 - 2,672 CDC i nvestments As noted previously, CDC typically invests in VIEs as a limited partner or investor member in the form of equity contributions and has no substantive kick-out or substantive participating rights over the managing member . 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 rul es and regulations necessary for the qualification of tax credits generated by equity investments. This power is held by the 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. During the fourth quarter of 2017, the Bancorp recognized $68 million of impairment on certain affordable housing investments primarily due to the change in the federal statutory corporate tax rate pursuant to the TCJA. This impairment charge was recorded in other noninterest expense in the Consolidated Statements of Income. Refer to Note 27 for further information. The Bancorp’s funding requirements are limited to its invested capital and any additional unfun ded 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 in vestments, which are included in other assets in the Consolidated Balance Sheets, and the liabilities related to the unfunded commitments, which are included in other liabilities in the Consolidated Balance Sheets, are included in the previous tables for a ll 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 p rojected tax credits to be received by the limited partners/investor members, thereby minimizing a portion of the Bancorp’s risk. At both December 31, 2017 and 2016 , the Bancorp’s CDC investments included $ 1.3 billion of investments in affordable hou sing tax credits recognized in other assets in the Consolidated Balance Sheets. The unfunded commitments related to these investments were $ 355 million and $ 349 million at December 31, 2017 and 2016 , respectively. The unfunded commitments as of Decem ber 31, 2017 are expected to be funded from 2018 to 2034. 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 Consolidated Statements of Income relating to investments in qualified affordable housing investments: Consolidated Statements of For the years ended December 31 ($ in millions) Income Caption 2017 2016 2015 Pre-tax investment and impairment losses (a) Other noninterest expense $ 207 144 126 Tax credits and other benefits Applicable income tax expense (246) (220) (205) (a) The Bancorp recognized $68 of impairment losses primarily due to the change in the federal statutory corporate tax rate during the year ended December 31, 2017 and did not recognize impairment losses resulting from the forfeiture or ineligibility of tax credits or othe r circumstances during the years ended December 31, 2017 , 2016 and 2015 . Private e quity i nvestments The Bancorp , through Fifth Third Capital Holdings, a wholly-owned indirect subsidiary of the Bancorp, invests as a limited partner in private equity investments 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 par tner responsible for appointing the fund manager. The Bancorp has not been appointed fund manager for any of these private equity investments . The funds finance primarily all of their activities from the partners’ capital contributions and investment retur ns. T he Bancorp has determined that it is not the primary beneficiary of the funds because it does not have the obligation to absorb the funds’ expected losses or the right to receive the funds’ expected residual returns that could potentially be significa nt to the funds and lacks the power to direct the activities that most significantly impact the economic performance of the funds . The Bancorp, as a limited partner, does not have substantive participating or substantive kick-out rights over the general pa rtner. 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 inv estments in the private equity inves tments . 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 Consolidated Balance Sheets, are included in previous tables. Also, a t December 31, 2017 and 2016 , the Bancorp’s unfunded commitment amounts to the private equity funds were $ 48 million and $ 56 million, respectively. As part of previous commitments, t he Bancorp made capi tal contributions to private equity investments of $ 11 million and $ 14 million during the years ended December 31, 2017 and 2016 , respe ctively. The Bancorp recognized a gain of $ 11 million on the sales of certain private equity funds during the year ended December 31, 2017 . The Bancorp recognized $ 1 million, $ 9 million and $ 1 million of OTTI primarily associated with certain nonconforming investments affected by the Volcker Rule during the year s ended December 31, 2017 , 2016 , 2015 , respec tively. Refer to Note 27 for further information. Loans p rovided 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 l oans 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 underlyin g 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 e xposure to loss is equal to the carrying amounts of the loans and unfunded commitments to the VIEs. The Bancorp’s o utstanding loans to these VIEs are included in commercial loans in Note 5 . As of December 31, 2017 and 2016 , the Bancorp’s unfunded commitments to these entities were $ 1.1 b illion and $ 937 m illion, 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, respe ctively. The Bancorp does not provide any implicit or explicit liquidity guarantees or principal value guarantees to these VIEs.

SALES OF RECEIVABLES AND SERVICING RIGHTS Residential Mortgage TDR Loan Sale In March of 2015, the Bancorp recognized a $ 37 million gain, included in other noninterest income in the 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 which have expired. Additionally, the Bancorp did not obtain servicing responsibilities on the sales of these loan s 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 Ba ncorp sold fixed and adjustable- rate residential mortgag e loans during the years ended December 31, 2017 , 2016 and 2015 . In those sales, the Bancorp obtained servicing responsibilities and provided certain standard representations and warranties, however the investors have no recourse to the Bancorp’s other assets for failure of debtors to pay wh en 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 Consolidated Statements of Income, for the years ended December 31 is as follows: ($ in millions) 2017 2016 2015 Residential mortgage loan sales (a) $ 6,369 6,927 5,078 (b) Origination fees and gains on loan sales 138 186 171 Gross mortgage servicing fees 206 199 222 Represents the unpaid principal balance at the time of the sale . Excludes $ 568 of HFS residential mortgage loans previously modified in a TDR that were sold d uring the first quarter of 2015. Servicing Righ ts Effective January 1, 2017, the Bancorp elected to prospectively adopt the fair value method for all classes of its residential mortgage servicing rights portfolio. Upon this election, all servicing rights are measured at fair value at each reporting date and changes in the fair value of servicing rights are reported in mort gage banking net revenue in the Consolidated Statements of Income in the period in which the changes occur. The election of the fair value method did not require a cu mulative effect adjustment to retained earnings as there was no difference between the carrying value of the servicing rights, net of valuation allowance, and the fair value. Prior to the election of the fair value method, servicing rights were in itially recorded at fair value and subsequently amortized in proportion to, and over the period of, estimated net servicing revenue. Servicing rights were assessed for impairment monthly, based on fair value, with temporary impairment recognized through a valuation allowance . The following tables present changes in the servicing rights related to residential mortgage and automobile loans for the years ended December 31: ($ in millions) 2017 Balance, beginning of period $ 744 Servicing rights originated - residential mortgage loans 127 Servicing rights acquired - residential mortgage loans 109 Changes in fair value: Due to changes in inputs or assumptions (a) (1) Other changes in fair value (b) (121) Balance, end of period $ 858 Primarily reflects changes in prepayment speed and OAS spread assumptions which are updated based on market interest rates.

Amortization expense recognized on servicing rights for the years ended December 31, 2016 and 2015 was $ 131 million and $ 140 million, respectively . The Bancorp maintains a non-qualifying hedging strategy to manage a portion of the risk associated with changes in the value of th e MSR portfolio. This strategy may include the purchase of free-standing derivatives and various available-for-sale and trading 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 OA S spreads , earnings rates and prepayment speeds. The fair value of the servicing asset is based on the p resent value of expected future cash flows. The following table displays the beginning and ending fair value of the servicing rights for the years ended December 31: ($ in millions) 2017 2016 Fixed-rate residential mortgage loans: Balance, beginning of period $ 722 757 Balance, end of period 841 722 Adjustable-rate residential mortgage loans: Balance, beginning of period 22 27 Balance, end of period 17 22 Fixed-rate automobile loans: Balance, beginning of period - 1 Balance, end of period - - The following table presents activity related to valuations of the MSR portfolio and the impact of the non-qualifying hedging strategy for the years ended December 31: ($ in millions) 2017 2016 2015 Securities gains, net - non-qualifying hedges on MSRs $ 2 - - Changes in fair value and settlement of free-standing derivatives purchased to economically hedge the MSR portfolio (a) 2 24 90 MSR fair value adjustment (a) (122) - - Recovery of MSR impairment (a) - 7 4 Included in mortgage banking net revenue in the Consolidated Statements of Income. 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, securitization, or purchase resulting from transactions completed during the years ended December 31 were as follows: 2017 2016 Weighted- Prepayment Weighted- Prepayment Average Life Speed OAS Spread Average Life Speed OAS Spread Rate (in years) (annual) (bps) (in years) (annual) (bps) Residential mortgage loans: Servicing rights Fixed 7.5 9.1 % 497 7.2 10.3 % 584 Servicing rights Adjustable 2.7 32.1 660 2.8 30.2 679 Based on historical credit experience, expected credit losses for residential mortgage loan servicing assets have been deemed immaterial, as the Bancorp sold the majority of the underlying loans without recourse. At December 31, 2017 and 2016 , the Bancorp serviced $ 60.0 billion and $ 53.6 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 December 31, 2017, 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 OAS spread are as follows: Prepayment OAS Speed Assumption Spread Assumption Fair Weighted-Average Life Impact of Adverse Change on Fair Value OAS Spread Impact of Adverse Change on Fair Value ($ in millions) (a) Rate Value (in years) Rate 10% 20% 50% (bps) 10% 20% Residential mortgage loans: Servicing rights Fixed $ 841 6.0 11.4 % $ (36) (69) (158) 549 $ (17) (33) Servicing rights Adjustable 17 3.3 24.6 (1) (2) (5) 785 - (1) (a) 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 variation s 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	13 . DERIVA TIVE FINANCIAL INSTRUMENTS T he 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 s peculative derivative positions. The Bancorp’s interest rate risk management strategy involves modifying the repricing charac teristics 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 inc lude interest rate swaps, interest rate floors, interest rate caps, forward contracts, forward starting interest rate swaps, options and swaptions. Interest rate swap contracts are exchanges of interest payments, such as fixed-rate payments for floating-ra te 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, a nd 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 rat e floors, mortgage options, TBA securities and interest rate swaps) to economically hedge prepayment volat ility. Principal-only swaps are total return swaps that are based on changes in the value of the underlying mortgage principal-only trust. TBA securities are a forward purchase agreement for a mortgage-backed securities trade whereby the terms of the security are u ndefined 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 inc lude 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 economically hedge s significant exposures related to these free-standing derivatives by entering into offsetting third-party contracts with approved, reputable and independent counterparties with substantially matching terms and currencies. C redit 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 minimi zed through credit approvals, limits, counterparty collateral and monitoring procedures. The fair value of derivative instruments is presented on a gross basis, even when the derivative instruments are subject to master netting arrangements. Derivative in struments with a positive fair value are reported in other assets in the Consolidated Balance Sheets while derivative instruments with a negative fair value are reported in other liabilities in the Consolidated Balance Sheets. Cash collateral payables and receivables associated with the derivative instruments are not added to or nette d against the fair value amounts with the exception of certain variation margin payments that are considered legal settlements of the derivative contracts. For derivative contr acts cleared through certain central clearing parties who have modified their rules to treat variation margin payments as settlements, the variation margin payments are applied to net the fair value of the respective derivative contracts. The Bancorp’s der ivative assets include c ertain 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 December 31, 2017 and 2016 , the balance of collateral held by the Bancorp for derivative assets was $ 409 million and $ 444 m illion, respectively. For derivative contracts cleared through certain central clearing parties who have modified their rules to treat variation margin payments as settlement of the derivative contract, the payments for variation margin of $ 74 million were applied to reduce the respective derivative contracts and were also not included in th e total amount of collateral held as of December 31, 2017 . The credit component negatively impacting the fair value of derivative assets associated with customer accommodation contracts as of December 31, 2017 and 2016 was $ 3 million and $ 6 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 wit h 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 December 31, 2017 and 2016 , the balance of collateral posted by the Bancorp for derivative liabilities was $ 365 million and $ 399 million, respectively. Additionally, $ 31 million of variation margin payments were applied to the resp ective derivative contracts to reduce the Bancorp’s derivative liabilities as of December 31, 2017 and were also not included in the total amount of collateral posted. Certain of the Bancorp’s derivative liabilities contain credit-risk related contingen t features that could result in the requirement to post additional collateral upon the occurrence of specified events. As of December 31, 2017 and 2016 , 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 Bancorp’s 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 determi ned that the impact of the Bancorp’s credit risk to the valuation of its derivative liabilities was immaterial to the Bancorp’s 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 accommodati on derivatives are he ld as free-standing derivatives. The following tables reflect the notional amounts and fair values for all derivative instruments included in the Consolidated Balance Sheets as of: Fair Value Notional Derivative Derivative December 31, 2017 ($ in millions) Amount Assets Liabilities Derivatives Designated as Qualifying Hedging Instruments Fair value hedges: Interest rate swaps related to long-term debt $ 3,705 297 5 Total fair value hedges 297 5 Cash flow hedges: Interest rate swaps related to C&I loans 4,475 - 12 Total cash flow hedges - 12 Total derivatives designated as qualifying hedging instruments 297 17 Derivatives Not Designated as Qualifying Hedging Instruments Free-standing derivatives - risk management and other business purposes: Interest rate contracts related to MSRs 11,035 54 15 Forward contracts related to residential mortgage loans held for sale 1,284 1 1 Stock warrant 20 20 - Swap associated with the sale of Visa, Inc.

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. For all interest rate swaps designated as fair value hedges as of December 31, 2017 , an assessment of hedge effectiveness using regression analysis was performed 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. Hedge ineffectiveness is the difference between the change s 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 ineffectivenes s on interest rate swaps hedging fixed-rate funding is reported within interest expense in the 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 Consolidated Statements of Income: Consolidated Statements of Income Caption For the years ended December 31 ($ in millions) 2017 2016 2015 Change in fair value of interest rate swaps hedging long-term debt Interest on long-term debt $ (33) (59) (29) Change in fair value of hedged long-term debt attributable to the risk being hedged Interest on long-term debt 31 54 25 Cash Flow Hedges 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 s hare the same risk exposure that the Bancorp desires to hedge. The Bancorp may also enter into interest rate caps and floors to limit ca sh flow variability of floating- rate assets and liabilities. As of December 31, 2017 , all hedges designated as cash flow hedges were asses sed 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 Consolidated Statements of Income. The effective portion of the cumulative gains or losses on cash flow hedges are reported within AOCI an d are reclassified from AOCI to current period earnings when the forecasted transaction affects earnings. As of December 31, 2017 , the maximum length of time over which the Bancorp is hedging its exposure to the variability in future cash flows is 24 months. Re classified gains and losses on interest rate contracts related to commercial and industrial loans are recorded within interest income in the Consolidated Statements of Income. As of December 31, 2017 and 2016 , $ 9 million of net deferred losses, net of tax and $ 10 million of net deferred gains, net of tax, respectively, on cash flow hedges were recorded in AOCI in the Consolidated Balance Sheets. As of December 31, 2017 , $ 3 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 December 31 , 2017 . D uring the years ended 2017 and 2016 , 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 . The following table presents the pre-tax net (losses) gains recorded in the Consolidated Statements of Income and in the Consolidated Statements of Comprehensive Income relating to derivative instruments designated as cash flow hedges: For the years ended December 31 ($ in millions) 2017 2016 2015 Amount of pre-tax net (losses) gains recognized in OCI $ (11) 30 74 Amount of pre-tax net gains reclassified from OCI into net income 19 48 75 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, TBA s ecurities and interest rate swaps) to economically hedge changes in fair value of its largely fixed-rate MSR portfolio. Principal-only swaps hedge the mortgage-LIBO R 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 en vironment. 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 va lue of certain residential mortgage loans held for sale du e to changes in interest rates. IRLC s issued on residential mortgage loan commitments that will be held for sale are also considered free-standing derivative instruments and the interest rate exposu re on these commitments is economically hedged pr imarily 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 Consolidate d Statements of Income. In conjunction with the initial sale of the Bancorp’s 51 % interest in Vantiv Holding, LLC in 2009 , the Ban corp received a warrant which was accounted for as a free-standing derivative . During the year ended December 31, 2015, the Bancorp bo th sold and exercised part of the warrant. During the year ended December 31, 2016, the Bancorp exercised the remaining portion of the warrant. In conjunction with the sale of Visa, Inc. Class B S hares 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 rat e of the Class B Shares into Class A S hares. This total return swap is accounted for as a free-standing derivative. Refer to Note 27 for further discu ssion of significant inputs and assumptions used in the valuation of this instrument. The net gains (losses) recorded in the Consolidated Statements of Income relating to free-standing derivative instruments used for risk management and other business purposes are summarized in the following table: Consolidated Statements of Income Caption For the years ended December 31 ($ in millions) 2017 2016 2015 Interest rate contracts: Forward contracts related to residential mortgage loans held for sale Mortgage banking net revenue $ (17) 14 8 Interest rate contracts related to MSR portfolio Mortgage banking net revenue 2 24 90 Foreign exchange contracts: Foreign exchange contracts for risk management purposes Other noninterest income (7) 2 23 Equity contracts: Stock warrant associated with Vantiv Holding, LLC Other noninterest income - 73 (a) 325 (a) Stock warrant Other noninterest income (1) - - Swap associated with sale of Visa, Inc. Class B Shares Other noninterest income (80) (56) (37) ( a) The Bancorp recognized a net gain of $ 9 on the exercise of the remaining warrant during the fourth quarter of 2016 and a net gain of $89 on both the sale and partial exercise of the warrant during the fourth quarter of 2015 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 specif ic assets or liabilities on the 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 banki ng revenue in the 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 the se 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 December 31, 2017 and 2016 , the total notional amount of the risk participation agreements was $2.8 billion and $2.5 billion, respectively , and the fair value w as a liability of $ 5 million at December 31, 2017 and $ 4 million at December 31, 2016 , which is included in other liabilities in the Consolidated Balance Sheets . As of December 31, 2017 , the risk participation agreements had a weighted- average remaining life of 2.9 year s. The Bancorp’s maximum exposure in the risk participation agreements is cont ingent 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 th e underlying customers in the risk participation agreements through the same risk grading system currently utilized for establishing loss reserves i n 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: At December 31 ($ in millions) 2017 2016 Pass $ 2,748 2,447 Special mention 66 14 Substandard 24 6 Total $ 2,838 2,467 The net gains (losses) recorded in the Consolidated Statements of Income relating to free-standing derivative instruments used for customer accommodation are summarized in the following table: Consolidated Statements of For the years ended December 31 ($ in millions) Income Caption 2017 2016 2015 Interest rate contracts: Interest rate contracts for customers (contract revenue) Corporate banking revenue $ 21 22 23 Interest rate contracts for customers (credit losses) Other noninterest expense (5) - (1) Interest rate contracts for customers (credit portion of fair value adjustment) Other noninterest expense 2 1 1 Interest rate lock commitments Mortgage banking net revenue 93 114 111 Commodity contracts: Commodity contracts for customers (contract revenue) Corporate banking revenue 6 6 5 Commodity contracts for customers (credit losses) Other noninterest expense 1 (1) (2) Commodity contracts for customers (credit portion of fair value adjustment) Other noninterest expense - 1 6 Foreign exchange contracts: Foreign exchange contracts for customers (contract revenue) Corporate banking revenue 48 62 70 Foreign exchange contracts for customers (credit losses) Other noninterest expense 2 (2) - Foreign exchange contracts for customers (credit portion of fair value adjustment) Other noninterest expense 1 1 - 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 amoun ts 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 der ivative liabilities on the Consolidated Balance Sheets on a gross basis, even when provisions allowing for setoff are in place. However, for derivative contracts cleared through certain central clearing parties who have modified their rules to treat variat ion margin payments as settlements, the fair value of the respective derivative contracts are reported net of the variation margin payments. Collateral amounts included in the table s below consist primarily of cash and highly-rated government-backed securi ties and do not include variation margin payments for derivative contracts with legal rights of setoff for the year ended December 31, 2017 . The following tables provide a summary of offsetting derivative financial instruments: Gross Amount Gross Amounts Not Offset in the Recognized in the Consolidated Balance Sheets As of December 31, 2017 ($ in millions) Consolidated Balance Sheets (a) Derivatives Collateral (b) Net Amount Assets: Derivatives $ 815 (213) (362) 240 Total assets 815 (213) (362) 240 Liabilities: Derivatives 602 (213) (155) 234 Total liabilities $ 602 (213) (155) 234 (a) Amount does not include IRLCs because these instruments are not subject to master netting or similar arrangements.

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 r ecognized in the 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 Consolidated Balance Sheets are discussed in the following sections. Commitments The Bancorp has certain commitments to make future payments under contracts. The following table reflects a summary of significant commitments as of December 31: ($ in millions) 2017 2016 Commitments to extend credit $ 68,106 67,909 Letters of credit 2,185 2,583 Forward contracts related to residential mortgage loans held for sale 1,284 1,823 Noncancelable operating lease obligations 568 576 Purchase obligations 144 57 Capital commitments for private equity investments 48 59 Capital expenditures 37 29 Capital lease obligations 26 19 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 a lso 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 both December 31, 2017 and 2016 , the Bancorp had a reserve for unfunded commitments , i ncluding letters of credit, totaling $ 161 million included in other liabilities in the Consolidated Balance Sheets. The Bancorp monitors the credit risk associated with commitments to extend credit using the same risk rating system uti lized withi n its loan and lease portfolio. Risk ratings under this risk rating system are summarized in the following table as of December 31: ($ in millions) 2017 2016 Pass $ 67,254 66,802 Special mention 330 338 Substandard 522 753 Doubtful - 16 Total commitments to extend credit $ 68,106 67,909 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 December 31, 2017: ($ in millions) Less than 1 year (a) $ 1,170 1 - 5 years (a) 999 Over 5 years 16 Total letters of credit $ 2,185 (a) Includes $ 7 and $ 1 issued on behalf of commercial customers to facilitate trade payments in U.S. dollars and foreign currencies which expire less than 1 year and between 1 - 5 years, respectively. Standby letters of credit accounted for approximately 99 % of total letters of credit at both December 31, 2017 and 2016 and are considered guarantees in accordance with U.S. GAAP. Approximately 61 % and 6 2 % of the total standby letters of credit were collateralized as of December 31, 2017 and 2016 , respectively . In the event of nonperformance by the customers, the Bancorp has rights to the underlying collateral, which can include commercial real estate, p hysical plant and property, inventory, receivables, cash and marketable securities.

As remarketing agent, FTS is responsible fo r finding purchasers for VRDNs that are put by investors. The Bancorp issued letters of credit, as a credit enhancement, to $ 331 million and $ 609 million of the VRDNs remarketed by FTS, in addition to $ 9 4 million and $ 145 million in VRDNs remarketed by thi rd parties at December 31, 2017 and 2016 , respectively.

The Bancorp uses the best information available when 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 Decembe r 31, 2017 , 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 $ 11 million in excess of amounts r eserved. 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 rec orded mortgage representation and warranty reserve or this estimate of reasonably possible losses, depending on the outcome of various factors, including those previously discussed . During both the years ended December 31, 2017 and 2016 , the Bancorp paid $ 1 million in the form of make whole payments and repurchased $ 12 million and $ 17 million, respectively, in outstanding principal of loans to satisfy investor demands. Total repurchase demand requests during the years ended December 31, 2017 and 2016 were $ 15 million and $ 22 million, respectively. Total outstanding repurchase demand inventory was $ 1 million at December 31, 2017 compared to $ 2 million at December 31, 2016 . The following table summarizes activity in the reserve for representation and warranty provisions for the years ended December 31: ($ in millions) 2017 2016 Balance, beginning of period $ 13 25 Net reductions to the reserve (3) (10) Losses charged against the reserve (1) (2) Balance, end of period $ 9 13 The following tables provide a rollforward of unresolved claims by claimant type for the years ended December 31: GSE Private Label 2017 ($ in millions) Units Dollars Units Dollars Balance, beginning of period 13 $ 2 - $ - New demands 109 15 1 - Loan paydowns/payoffs (2) - - - Resolved demands (114) (16) - - Balance, end of period 6 $ 1 1 $ - GSE Private Label 2016 ($ in millions) Units Dollars Units Dollars Balance, beginning of period 16 $ 4 2 $ - New demands 309 22 4 - Loan paydowns/payoffs (8) (1) - - Resolved demands (304) (23) (6) - Balance, end of period 13 $ 2 - $ - 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 v alue securing the loan. The outstanding balances on these loans sold with credit recourse were $ 312 million and $ 374 million at December 31, 2017 and 2016 , respectively, and the delinquency rates were 3.0 % at December 31, 2017 and 3.2 % at December 31, 2016 . The Bancorp maintained an estimated credit loss reserve on these loans sold with credit recourse of $ 5 million and $ 7 million at December 31, 2017 and 2016 , respectively, recorded in other liabilities in the Consolidated Balance Sheets. To determine th e 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 n indirect wholly-owned sub sidiary 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 $ 15 million at both December 31, 2017 and 2016 . In the event of an y 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 both December 31, 2017 and 2016 . Visa litigation The Bancor p, 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 accordanc e 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 reorgani zation 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 recog nize 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 classi fied in other assets and accounted for at their carryover basis of $ 0 . Visa 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 retur n 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 27 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 Cl ass 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 Vis a 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 Sh ares 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 amoun t 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 the Vi sa Class B Shares and through December 31, 2017 , 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 the Class B Shares, the Bancorp reversed its net Vi sa litigation reserve liability and recognized a free-standing derivative liability associated with the total return swap. The fair value of the swap liability was $ 137 million and $ 91 million at December 31, 2017 and 2016 , respectively. Refer to Note 13 and Note 27 for further information. After the Bancorp’s sale of the Class B Shares, Visa has funded additional amounts into the litigation escrow account which have resulted in further dilutive adjustments to the conversion of Class B Shares into C lass A Shares, and along with other terms of the total return swap, required the Bancorp to make cash payments in varying amounts to the swap counterparty as follows: Visa Bancorp Cash Period ($ in millions) Funding Amount Payment Amount Q2 2010 $ 500 20 Q4 2010 800 35 Q2 2011 400 19 Q1 2012 1,565 75 Q3 2012 150 6 Q3 2014 450 18

Legal And Regulatory Proceedings
Legal and Regulatory Proceedings	18 . LEGAL AND REGULATORY PROCEEDINGS Litigation Visa/Mastercard Merchant Interchange Litigation In 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 (In re: Payment Card Interchange Fee and Merchant Discount Antitrust Litigation). 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 po ssible indemnification obligatio n of Visa as discussed in Note 17 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 settlem ent agreement. On January 14, 2014, the trial court entered a final order approving the class settlement. A number of merchants filed appeals from that approval. The U.S. Court of Appeals for the Second Circuit held a hearing on those appeals and on June 3 0, 2016, reversed the district court’s approval of the class settlement, remanding the case to the district court for further proceedings. On March 27, 2017, the Supreme Court of the United States denied a petition for writ of certiorari seeking to review the Second Circuit’s decision. Pursuant to the terms of the overturned settlement agreement, the Bancorp previously paid $ 46 million into a class settlement escrow account. Because the appellate court ruling remands the case to the district court for furth er proceedings, the ultimate outcome in this matter is uncertain. Approximately 8,000 merchants requested exclusion from the class settlement, and therefore, pursuant to the terms of the overturned settlement agreement, approximately 25% of the funds paid into the class settlement escrow account were already returned to the control of the defendants. The remaining approximately 75% of the settlement funds paid by the Bancorp are maintained in the escrow account. More than 500 of the merchants who requested exclusion from the class filed separate federal lawsuits against Visa, MasterCard and certain other defendants alleging similar antitrust violations. These individual federal lawsuits were transferred to the United States District Court for the Eastern Dis trict of New York. While t he Bancorp is only named as a defendant in one of the individual federal lawsuits, i t may have obligations pursuant to indemnification arrangements and/or the judgment or loss sharing agreements noted above. Refer to Note 17 f or further information. Klopfenstein v. Fifth Third Bank On August 3, 2012, William Klopfenstein and Adam McKinney filed a lawsuit against Fifth Third Bank in the United States District Court for the Northern District of Ohio (Klopfenstein et al. v. Fifth Third Bank), alleging that the 120% APR that Fifth Third disclosed on its Early Access program was misleading. Early Access is a deposit-advance program offered to eligible customers with checking accounts. The plaintiffs sought to represent a nationwide class of customers who used the Early Access program and repaid their cash advances within 30 days. On October 31, 2012, the case was transferred to the United States District Court for the Southern District of Ohio. In 2013, four similar putative class ac tions were filed against Fifth Third Bank in federal courts throughout the country (Lori and Danielle Laskaris v. Fifth Third Bank, Janet Fyock v. Fifth Third Bank, Jesse McQuillen v. Fifth Third Bank, and Brian Harrison v. Fifth Third Bank). Those four la wsuits were transferred to the Southern District of Ohio and consolidated with the original lawsuit as In re: Fifth Third Early Access Cash Advance Litigation. On behalf of a putative class, the plaintiffs seek unspecified monetary and statutory damages, i njunctive relief, punitive damages, attorney’s fees, and pre- and post-judgment interest. On March 30, 2015, the court dismissed all claims alleged in the consolidated lawsuit except a claim under the federal Truth-In-Lending Act . No trial date has been sc heduled. Nina Investments, LLC v. Fifth Third Bank On July 5, 2012, Nina Investments, LLC (“Nina”) filed a lawsuit against Fifth Third Bank (Nina Investments, LLC. v. Fifth Third Bank, et al.) in the Circuit Court of Cook County, Illinois, alleging fraud and conspiracy to commit fraud related to a credit facility established by Fifth Third Bank in 2007 to finance life insurance premiums. Nina invested funds in an entity related to the borrower under the credit facility and is claiming over $ 70 million in d amages based on its alleged loss of these funds. Nina alleges that it would have made different investment decisions if Fifth Third had disclosed fraud committed by the borrower with the alleged knowledge of Fifth Third employees. Nina filed this lawsuit i n response to a lawsuit filed by Fifth Third Bank in the same court on June 11, 2010 against Nina and other defendants (Fifth Third Bank v. Concord Capital Management, LLC, et al.) alleging fraud and breach of contract. In 2015, the court dismissed Fifth T hird’s contract and fraud claims against certain defendants. On March 17, 2017, after hearing motions for summary judgment, the court dismissed, in part, Nina’s fraud claims against Fifth Third, Fifth Third’s claims against the other defendants and Fifth T hird’s claim for fraudulent conveyance against Nina. On June 9, 2017, the parties entered into a confidential settlement agreement fully and finally resolving their respective claims in this action within existing accruals for this matter and before accoun ting for any recovery on related insurance policies. The Court entered an order dismissing the matter with prejudice on June 20, 2017. H elton v. Fifth Third Bank On August 31, 2015, trust beneficiaries filed an action against Fifth Third Bank, as trustee, in the Probate Court for Hamilton County, Ohio (Helen Clarke Helton, et a l. v. Fifth Third Bank). The plaintiffs allege breach of the duty to diversi f y, breach of the duty of impartiality, breach of trust/fiduciary duty, and unjust enrichment, based on Fi fth Third’s alleged failure to diversify assets held in two trusts f or the plaintiffs’ benefit. The lawsuit seeks over $ 800 million in alleged damages, attorney’s fees, removal of Fifth Third as trustee, and injunctive relief. Fifth Third denies all liabil ity. On January 5, 2016, the Court denied Fi fth Third’s motion to dismiss. On January 4, 2018, Fifth Third moved for summary judgment seeking dismissal of all the plaintiffs’ claims on statute of limitations and other grounds. Plaintiffs also moved for su mmary judgment on their breach of fiduciary duty claim. Trial is currently scheduled for June 18, 2018 . Upsher-Smith Laboratories, Inc. v. Fifth Third Bank On February 12, 2016 , Upsher-Smith Laboratories, Inc. (“Upsher-Smith”) filed suit against Fifth Third Bank in the Fourth Judicial District, Hennepin County, Minnesota (Upsher-Smith Laboratories Inc. v. Fifth Third Bank), alleging that Fifth Third improperly implemented foreign exchange transactions requested by plaintiff’s authorized employee who all egedly was the victim of fraud by a third party. Plaintiff asserts claims for breach of contract and the implied covenant of good faith and fair dealing under Article 4A-202 of the Uniform Commercial Code, with losses allegedly totaling almost $40 million. Fifth Third denies all liability in this matter. On March 3, 2016, Fifth Third removed the case to the United States District Court for the District of Minnesota. Fifth Third filed a motion to transfer venue to the United States District Court for the Sou thern District of Ohio on April 7, 2016, which was denied on December 29, 2016. No trial date has been scheduled. The Champions Home Owners Association, Inc. v. Jeffrey D. Quammen, et al. On July 12, 2017, Fifth Third Bank and Royce Pulliam, P&P Re al Estate, LLC and Global Fitness Holdings, LLC (“Plaintiffs”) entered into a settlement agreement pursuant to which the Plaintiffs paid Fifth Third Bank $2.2 million following a 2017 bench trial and ruling and award in favor of Fifth Third Bank in the Cir cuit Court of Jessamine County, Kentucky. The Plaintiffs had filed their cross-complaint against Fifth Third Bank on September 12, 2013, alleging that Fifth Third Bank breached a contract to provide commercial funding for Plaintiffs’ national fitness franc hise. The Plaintiffs claimed to have sustained over $50 million in damages from the alleged contract breach. Fifth Third Bank denied that any breach of contract occurred, and further asserted that Plaintiffs executed multiple releases waiving the claims at issue in the litigation. Other l itigation 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 that the resulting liability, if any, from these other actions would not have a material effect upon the Bancorp’s consolidated financial posi tion, results of operations or cash flows. Governmental Investigations and Proceedings The Bancorp and/or its affiliates are or may become involved in information-gathering requests, reviews, investigations and proceedings (both formal and informal) by various governmental regulatory agencies and law enforcement authorities, including but not limited to the FRB, CFPB, SEC, FINRA, U.S. Depart ment of Justice, etc., as well as state and other governmental authorities and 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 consequ ences 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 en forcement. Additionally, in some cases, regulatory authorities may take supervisory actions that are considered to be confidential supervisory information which may not be publicly disclosed. Reasonably Possible Losses in Excess of Accruals The Bancorp and its subsidiaries are parties 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 res olution are inherently difficult to predict. The following factors, among others, contribute to this lack of predictability: 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 f or 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 appr opriate 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. GA AP, 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 in an aggregate amount up to approximately $ 31 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 informatio n, 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 t he 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 .

Related Party Transactions
Related Party Transactions	19 . RELATED PARTY TRANSACTIONS The Bancorp maintains written policies and procedures covering related party transactions with principal shareholders, directors and executives of the Bancorp. These procedures cover transactions such as employee-stock purchase loans, personal lines of credit, residential secured loans, overdrafts, letters of credit and increases in indebtedness. Such transactions are subject to the Bancorp’s normal underwriting and approval procedures. Prior to approving a loan to a related party, Compliance Risk Manage ment must review and determine whether the transaction requires approval from or a post notification to the Bancorp’s Board of Directors. At December 31, 2017 and 2016 , certain directors, executive officers, principal holders of Bancorp common stock and thei r related interests were indebted, including undrawn commitments to lend, to the Bancorp’s banking subsidiary. The following table summarizes the Bancorp’s lending activities with its principal shareholders, directors, executives and their related interests at December 31: ($ in millions) 2017 2016 Commitments to lend, net of participations: Directors and their affiliated companies $ 546 618 Executive officers 6 4 Total $ 552 622 Outstanding balance on loans, net of participations and undrawn commitments $ 20 54 The commitments to lend are in the form of loans and guarantees for various business and personal interests. This indebtedness was incurred in the ordinary course of business on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated parties. This indebtedness does not involve more than the normal risk of repayment or present other features unfavorable to the Bancorp. Vantiv Holding, LLC On June 30, 2009, the Ban corp completed the sale of a majority interest in its p rocessing b usiness, Vantiv Holding, LLC . Advent International acquired an approximate 51% interest in Vantiv Holding, LLC for cash and a warrant . The Bancorp retained the remaining approximate 49 % inte rest in Vantiv Holding, LLC. During the first quarter of 2012, Vantiv, Inc. priced an IPO of its shares and contributed the net proceeds to Vantiv Holding, LLC for additional ownership interests. As a result of this offering, the Bancorp’s ownership of Va ntiv Holding, LLC was reduced to approximately 39%. The impact of the capital contributions to Vantiv Holding, LLC and the resulting dilution in the Bancorp’s interest resulted in a gain of $ 115 million recognized by the Bancorp i n the first quarter of 201 2. The following table provides a summary of the sales transactions that impacted the Bancorp's ownership interest in Vantiv Holding, LLC after the initial IPO: Remaining Ownership ($ in millions) Gain on Sale Percentage (a) Q4 2012 $ 157 33.1 % Q2 2013 242 27.7 Q3 2013 85 25.1 Q2 2014 125 22.8 Q4 2015 331 18.3 Q3 2017 1,037 8.6 (a) The Bancorp’s remaining investment in Vantiv Holding, LLC of $ 219 as of December 31, 201 7 was accounted for as an equity method investment in the Bancorp’s Consolidated Financial Statements. The Bancorp agreed during the fourth quarter of 2015 to cancel rights to purchase approximately 4.8 million Class C Units in Vantiv Holding, LLC, the wholly-owned principal operating subsidiary of Vantiv, Inc., underlying the warrant in exchange for a cash payment of $200 million. Subsequent to this cancellation, the Bancorp exercised its right to purchase approximately 7.8 million Class C Units underlying the warrant at the $15.98 strike price. This exercise was settled on a net basis for approximately 5.4 million Class C Units, which were then exchanged for approximately 5.4 million shares of Vantiv, Inc. Class A Common Stock that were sold in the secondary offering. The Bancorp recognized a gain of $89 million in other noninterest income on the 62% of the warrant that was settled or net exercised. Additionally, during the fourth quarter of 2015, the Bancorp exchanged 8 million Class B Units of Vantiv Holding, LLC for 8 million Class A Shares in Vantiv, Inc., which were also sold in the secondary offeri ng and on which the Bancorp recognized a gain of $331 million in other noninterest income. During the fourth quarter of 2016, the Bancorp exercised its right to purchase approximately 7.8 million Class C Units underlying the warrant at the $15.98 strike p rice. This exercise was settled on a net basis for approximately 5.7 million Class C Units, which were then exchanged for approximately 5.7 million shares of Vantiv, Inc. Class A Common Stock of which 4.8 million shares were sold in a secondary offering an d 0.9 million shares were repurchased by Vantiv, Inc. The Bancorp recognized a gain of $9 million in other noninterest income in the Consolidated Statements of Income in 2016 on the exercise of the remaining warrant in Vantiv Holding, LLC. During the third quarter of 2017, the Bancorp and Fifth Third Bank entered into a transaction agreement with Vantiv, Inc. and Vantiv Holding, LLC under which Fifth Third Bank agreed to exercise its right to exchange 19.79 million of its Class B Units in Vantiv Holding, LL C for 19.79 million shares of Vantiv, Inc.’s Class A Common Stock and Vantiv, Inc. agreed to repurchase the newly issued shares of Class A Common Stock upon issue directly from Fifth Third Bank at a price of $64.04 per share, the closing share price of the Class A Common Stock on the New York Stock Exchange on August 4, 2017. As a result of these transactions, the Bancorp recognized a gain of approximately $ 1.0 billion during the third quarter of 201 7. As of December 31, 2017 , the Bancorp continued to h old ap proximately 15 million Class B U nits of Vantiv Holding, LLC whic h may be exchanged for Class A Common S tock of Vantiv, Inc. (now Worldpay, Inc.), on a one-for-one basis or at Worldpay , Inc.’s option for cash which represented approximately 8.6% owner ship of Vantiv Holding, LLC as of December 31, 2017 . In addition, the Bancorp holds ap proximately 15 million Class B Common S har es of Worldpay, Inc. which give the Bancorp voting rights, but no ec onomic interest in Worldpay, Inc. These securities are su bject to certain terms and restrictions. For more information on a subsequent event related to Vantiv Holding, LLC, refer to Note 31 . The Ban corp recognized $47 million, $66 million and $63 million, respectively, in other noninterest income as part of its equity method investment in Vantiv Holding , LLC for the years ended December 31, 2017 , 2016 and 2015 and received cash distributions totaling $ 19 million , $ 9 million and $ 11 milli on during the year s ended December 31, 2017 , 2016 and 2015 , respectively. Given the nature of Vantiv Holding, LLC’s structure as a limited liability company and contractual arrangements with Vantiv Holding, LLC, the Bancorp’s remaining investment in Vantiv Holding, LLC continues to be accounted for under the equity method of accounting as of December 31, 2017. During the fourth quarter of 2015, the Bancorp entered into an agreement with Vantiv, Inc. under which a portion of its TRA with Vantiv, In c. was terminated and settled in full for a cash payment of approximately $49 million from Vantiv, Inc. Under the agreement, the Bancorp sold certain TRA cash flows it expected to receiv e from 2017 to 2030, totaling to a then estimated $140 million. Approx imately half of the sold TRA cash flows related to 2025 and later. This sale did not impact the TRA payment recognized during the fourth quarter of 2015. During the third quarter of 2016, the Bancorp entered into an agreement with Vantiv, Inc. under which a portion of its TRA with Vantiv, Inc. was terminated and settled in full for consideration of a cash payment in the amount of $116 million from Vantiv, Inc. Under the agreement, the Bancorp terminated and settled certain TRA cash flows it expected to rec eive in the years 2019 to 2035, totaling to a then estimated $331 million. The Bancorp recognized a gain of $116 million in other noninterest income from this settlement. Additionally, the agreement provides that Vantiv, Inc. may be obligated to pay up to a total of approximately $171 million to the Bancorp to terminate and settle certain remaining TRA cash flows, totaling to a then estimated $394 million, upon the exercise of certain call options by Vantiv, Inc. or certain put options by the Bancorp. In 20 16, the Bancorp recognized a gain of $164 million in other noninterest income associated with these options. The Bancorp received $ 63 million in settlement for the call options and put options exercised during 2017 . If the remaining associated call options or put options are exercised during 2018, the Bancorp expects to receive $ 108 million in 2018. This agreement did not impact the TRA payments recognized in the fourth quarter of both 2017 and 2016 . In addition to the impact of the TRA termination s discuss ed above, the Bancorp recognized $44 million , $3 3 million and $31 million in other noninterest income in the Consolidated Statements of Income associated with the TRA during the years ended December 31, 2017 , 2016 and 2015 , respectively. The following table provides the estimated cash flows to be received as of December 31, 2017 associated with the TRA for the years ending December 31, 2018 and thereafter: Cash Flows to be Received Estimated Cash Flows to from Put/Call Option be Received not Subject ($ in millions) Exercises (Fixed Amounts) (b) to Put/Call Option (a) 2018 108 44 2019 - 20 2020 - 25 2021 - 26 2022 - 26 2023 - 27 2024 - 27 2025 - 28 2026 - 29 Thereafter - 279 Total $ 108 531 (a) The 2018 cash flow of $44 has been agreed upon with Vantiv, Inc.

The remaining estimated cash flows in this column (which include TRA benefits associated with the net exercise of the warrant in 2016 and the subsequent exchange of Vantiv Holding units in the third quarter of 2017) will be recognized in future periods when the related uncertainties are resolved. ( b) As part of the agreement the Bancorp entered into with Vantiv, Inc. on July 27, 2016, Vantiv, Inc. made payments to the Bancorp of $63 during the year ended December 31, 2017 and may be obligated to pay a total of approximately $108 to the Bancorp to terminate certain remaining TRA cash flows, initially estimated to be $394, upon the exercise of certain call options by Vantiv, Inc.

The services provided by the Bancorp to Vantiv Holding, LLC were initially required to support Vantiv Holding, LLC as a standalone entity during the deconversion period. The majority of services previously provided by the Bancorp to support Vantiv Holding, Inc. as a standalone entity are no longer necessary and are now limited to certain general business resources. Vanti v Holding, LLC paid the Bancorp $ 1 million for these services for each of the years ended December 31, 2017 , 2016 and 2015 .

In addition to the previously menti oned services, the Bancorp previously entered into an agreement under which Vantiv Holding, LLC will provide processing services to the Bancorp. The total amount of fees relating to the processing services provided to the Bancorp by Vantiv Holding, LLC tot aled $ 72 million , $ 76 million and $ 8 9 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. These fees are reported as a component of card and processing expense in the Consolidated Statements of Income.

Income Taxes	20 . IN COME TAXES The Bancorp and its subsidiaries file a consolidated federal income tax return. The following is a summary of applicable income taxes included in the Consolidated Statements of Income for the years ended December 31: ($ in millions) 2017 2016 2015 Current income tax expense: U.S. Federal income taxes $ 763 598 662 State and local income taxes 68 55 55 Foreign income taxes (3) - 13 Total current income tax expense 828 653 730 Deferred income tax benefit: U.S. Federal income taxes (252) (133) (78) State and local income taxes 1 (14) 6 Foreign income taxes - (1) 1 Total deferred income tax benefit (251) (148) (71) Applicable income tax expense $ 577 505 659 The following is a reconciliation between the federal statutory corporate tax rate and the Bancorp’s effective tax rate for the years ended December 31: 2017 2016 2015 Federal statutory corporate tax rate 35.0 % 35.0 35.0 Increase (decrease) resulting from: State taxes, net of federal benefit 1.6 1.3 1.7 Tax-exempt income (1.2) (2.7) (1.7) Low-income housing tax credits (6.0) (7.9) (6.6) Other tax credits (0.5) (0.9) (0.9) U.S. tax legislation impact on deferred taxes (7.9) - - Other, net (0.2) (0.4) 0.3 Effective tax rate 20.8 % 24.4 27.8 Other tax credits in the rate reconciliation table include New Markets, Rehabilitation Investment and Qualified Zone Academy Bond tax credits. Tax-exempt income in the rate reconciliation table includes interest on municipal bonds, interest on tax-exempt lending, income on life insurance policies held by the Bancorp, and certain gains on sales of leases that are exempt from federal taxation . On December 22, 2017, the U.S. government enacted comprehensive tax legislation known as the TCJA. The TCJA makes br oad and complex changes to the U.S. tax code including, but not limited to, reducing the top federal statutory corporate tax rate from 35 percent to 21 percent effective for tax years beginning after December 31, 2017. U.S. GAAP requires the Bancorp to rec ognize the tax effects of changes in tax laws and rates on its deferred taxes in the period in which the law is enacted. As a result, for the year ended December 31, 2017, the Bancorp remeasured its deferred tax assets and liabilities and recognized an inc ome tax benefit of approximately $ 220 million . The following table provides a reconciliation of the beginning and ending amounts of the Bancorp’s unrecognized tax benefits: ($ in millions) 2017 2016 2015 Unrecognized tax benefits at January 1 $ 24 13 11 Gross increases for tax positions taken during prior period 17 9 1 Gross decreases for tax positions taken during prior period (1) - - Gross increases for tax positions taken during current period 3 2 2 Settlements with taxing authorities (7) - - Lapse of applicable statute of limitations (2) - (1) Unrecognized tax benefits at December 31 (a) $ 34 24 13 (a ) Amounts represent unrecognized tax benefits that, if recognized, would affect the annual effective tax rate. The Bancorp’s unrecognized tax benefits as of December 31, 2017, 2016 and 2015 primarily relate to state income tax exposures from taking tax positions where the Bancorp believes it is likely that, upon examination, a state will take a position contrary to the position taken by the Bancorp. 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 twelve months, the Bancorp be lieves it is unlikely that its unrecognized tax benefits will change by a material amount durin g the next twelve months. Deferred income taxes are comprised of the following items at December 31: ($ in millions) 2017 2016 Deferred tax assets: Allowance for loan and lease losses $ 251 439 Deferred compensation 77 122 Reserve for unfunded commitments 34 56 Reserves 29 57 State net operating loss carryforwards 9 9 Other 102 223 Total deferred tax assets $ 502 906 Deferred tax liabilities: Lease financing $ 616 940 MSRs and related economic hedges 111 202 State deferred taxes 64 64 Bank premises and equipment 42 61 Investments in joint ventures and partnership interests 34 219 Other comprehensive income 21 34 Other 137 173 Total deferred tax liabilities $ 1,025 1,693 Total net deferred tax liability $ (523) (787) At both December 31, 2017 and 2016, the Bancorp recorded deferred tax assets of $ 9 million, related to state net operating loss carryforwards. The deferred tax assets relating to state net operating losses (primarily resulting from leasing operations) are presented net of specific valuation allowances of $ 27 million and $ 25 million at December 31, 2017 and 2016, respectively. If these carryforwards are not utilized, they will expire in varying amounts through 2037. At December 31, 2017 and 2016, the Bancor p recorded a deferred tax asset of $ 2 million and $ 3 million, respectively, related to a foreign tax credit carryforward. If not utilized, the deferred tax asset relating to the foreign tax credit carryforward will begin to expire in 2025. The Bancorp has determined that a valuation allowance is not needed against the remaining deferred tax assets as of December 31, 2017 or 2016. The Bancorp considered all of the positive and negative evidence available to determine whether it is more likely than not that t he deferred tax assets will ultimately be realized and, based upon that evidence, the Bancorp believes it is more likely than not that the deferred tax assets recorded at December 31, 2017 and 2016 will ultimately be realized. The Bancorp reached this conc lusion as the Bancorp has taxable income in the carryback period and it is expected that the Bancorp’s remaining deferred tax assets will be realized through the reversal of its existing taxable temporary differences and its projected future taxable income . The IRS has concluded its examination of the Bancorp’s 2012 and 2013 federal income tax returns and is currently examining the Bancorp’s 2014 federal income tax return. The statute of limitations for the Bancorp’s federal income tax returns remains open for tax years 2012-2017. On occasion, as various state and local taxing jurisdictions examine the returns of the Bancorp and its subsidiaries, the Bancorp may agree to extend the statute of limitations for a reasonable period of time. Otherwise, the statu tes of limitations for state income tax returns remain open only for tax years in accordance with each state’s statutes. Any interest and penalties incurred in connection with income taxes are recorded as a component of income tax expense in the Consolidat ed Financial Statements. During the years ended December 31, 2017 and 2016, the Bancorp recognized $ 2 million and $ 1 million, respectively, of interest expense in connection with income taxes and an immaterial amount of interest benefit for the year ended December 31, 2015. At December 31, 2017 and 2016, the Bancorp had accrued interest liabilities, net of the related tax benefits, of $ 3 million and $ 1 million, respectively. No material liabilities were recorded for penalties related to income taxes. Retain ed earnings at December 31, 2017 and 2016 included $ 157 million in allocations of earnings for bad debt deductions of former thrift subsidiaries for which no income tax has been provided. Under current tax law, if certain of the Bancorp’s subsidiaries use these bad debt reserves for purposes other than to absorb bad debt losses, they will be subject to federal income tax at the current federal statutory corporate tax rate.

Retirement and Benefit Plans
Retirement and Benefit Plans	21 . RETIR EMENT AND BENEFIT PLANS The Bancorp’s qualified defined benefit plan’s benefits were frozen in 1998, except for grandfathered employees. The Bancorp’s other retirement plans consist of non - qualified defined benefit plans which are frozen and funded on an as needed basis. A majority of these plans were obtained in acquisitions from prior years and are included with the qualified defined benefit plan in the following tables (“the Plan”) . The Bancorp recognizes the overfunded and underfu nded status of the Plan as an ass et and l iability, respectively, in the Consolidated Balance Sheets. The Plan had an underfunded projected benefit obligation at both December 31, 2017 and 2016 . The underfunded amounts recognized in other liabilities in the Consolidated Balance Sheets were $ 2 4 million and $ 34 million at December 31, 2017 and 2016 , respectively. The following table summarizes the Plan as of and for the years ended December 31: ($ in millions) 2017 2016 Fair value of plan assets at January 1 $ 172 166 Actual return on assets 28 11 Contributions 6 20 Settlement (11) (15) Benefits paid (10) (10) Fair value of plan assets at December 31 $ 185 172 Projected benefit obligation at January 1 $ 206 220 Interest cost 8 9 Settlement (11) (15) Actuarial loss 16 2 Benefits paid (10) (10) Projected benefit obligation at December 31 $ 209 206 Underfunded projected benefit obligation at December 31 $ (24) (34) Accumulated benefit obligation at December 31 (a) $ 209 206 (a) Since the Plan’s benefits are frozen , the rate of compensation increase is no longer an assumption used to calculate the accumulated benefit obligation. Therefore, the accumulated benefit obligation was the same as the projected benefit obligation at both December 31, 2017 and 2016 . T he estimated net actuarial loss for the Plan that will be amortized from AOCI into net periodic benefit cost during 2018 is $ 7 million. The estimated net prior service cost for the Plan that will be amortized from AOCI into net periodic benefit cost during 2018 is immaterial to the Consolidated Financial Statements. The following table summarizes net periodic benefit cost and other changes in the Plan's assets and benefit obligations recognized in OCI for the years ended December 31: ($ in millions) 2017 2016 2015 Components of net periodic benefit cost: Interest cost $ 8 9 9 Expected return on assets (10) (11) (13) Amortization of net actuarial loss 7 11 10 Settlement 4 7 7 Net periodic benefit cost $ 9 16 13 Other changes in plan assets and benefit obligations recognized in other comprehensive income: Net actuarial (gain) loss $ (1) 2 9 Amortization of net actuarial loss (7) (11) (10) Settlement (4) (7) (7) Total recognized in other comprehensive income (12) (16) (8) Total recognized in net periodic benefit cost and other comprehensive income $ (3) - 5 Fair Value Measurements of Plan Assets The following tables summarize plan assets measured at fair value on a recurring basis as of December 31: Fair Value Measurements Using (a) 2017 ($ in millions) Level 1 Level 2 Level 3 Total Fair Value Equity securities $ 73 - - 73 Mutual and exchange-traded funds: Money market funds 7 - - 7 International funds - 30 - 30 Domestic funds - 29 - 29 Debt funds - 1 - 1 Alternative strategies 1 9 - 10 Commodity funds 5 - - 5 Total mutual and exchange-traded funds $ 13 69 - 82 Debt securities: U.S. Treasury and federal agencies securities 8 2 - 10 Mortgage-backed securities: Agency residential mortgage-backed securities - 1 - 1 Agency commercial mortgage-backed securities - 2 - 2 Non-agency commercial mortgage-backed securities - 1 - 1 Asset-backed securities and other debt securities (b) - 16 - 16 Total debt securities $ 8 22 - 30 Total plan assets $ 94 91 - 185 For further information on fair value hierarchy levels, refer to Note 1 .

Includes holdings in Bancorp common stock. Includes corporate bonds. The following is a description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy. Equity securities The P lan measures common stock using quoted prices which are available in an active market and classifies these investments within Level 1 of the valuation hierarchy. Mutual and exchange- traded funds All of the Plan’s mutual and exchange- traded funds are publicly traded. The P lan meas u res the value of these investments using the fund’s quoted prices which are available in an active market and classifies these investments within Level 1 of the valuation hierarchy. Level 1 securities include money market funds, alternative strategies and commodity funds. Where quoted prices are not available, the Plan measures the fair value of these investments based on the redemption price of units held, which is based on the current fair value of the fund’s underlyi ng assets. Unit values are determined by dividing the fund’s net assets at fair value by its units outstanding at the valuation dates to obtain the investment’s net asset value. Therefore, investments such as international funds, domestic funds, debt funds and alternative strategies are classified within Level 2 of the valuation hierarchy. Debt securities Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include U. S. Treasury securities. If quoted market prices are not available, the n 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 securities, agency residential mortgage-backed securities, agency commercial mortgage-backed securities, non-agency commercial mortgage-backed securities and asset-backed securities and other debt securities. Plan Assumptions The P lan ’s assumptions are evaluated annually and are updated as necessary. The discount rate assumption reflects the yield on a portfolio of high quality fixed-income instruments th at have a similar duration to the P lan’s liabilities. The expected long-term rate of return assumption reflects the average return expected on the assets invested to provide for the P lan’s liabilities. In determining the expected long-term rate of return, the Bancorp evaluated actuarial and economic inputs, including long-term inflation rate assumptions and broad equity and bond indices long-term return projections, as well as actual long-t erm historical plan performance. The following table summarizes the weighted-average plan assumptions for the years ended December 31: 2017 2016 2015 For measuring benefit obligations at year end: (a) Discount rate 3.47 % 3.97 4.16 Expected return on plan assets 6.00 7.00 7.00 For measuring net periodic benefit cost: (a) Discount rate 3.97 4.16 3.82 Expected return on plan assets 6.00 7.00 7.00 (a) Since the Plan’s benefits were frozen , except for grandfathered employees, the rate of compensation increase is no longer applicable beginning in 2014 since minimal grandfathered employees are still accruing benefits. Lowering both the expected rate of return on the plan assets and the discount rate by 0.25% would have increased the 2017 pension expense by approximately $ 1 million. Based on the actuarial assumptions, the Bancorp expects to contribute $ 3 million to the Plan in 2018 . Esti mated pension benefit payments are $ 17 million for each of the years 2018 through 2022 . The total estimated payments for the years 202 3 through 202 7 is $ 77 million. Investment Policies and Strategies The Bancorp’s policy fo r the investment of plan assets is to employ investment strategies that achieve a range of weighted-average target asset allocations relating to equity securities (including the Bancorp’s common stock), fixed- income securities (including U.S. Treasury and federal agencies securities , mortgage-backed securities, asset-backed securities and corporate bonds ) , alternative strategies (including traditional mutual funds, precious metals and commodities) and cash. The following table provides the Bancorp’s targeted and actual weighted-average asset allocations by asset category for the years ended December 31: Targeted Range (b) 2017 2016 Equity securities 76 % 73 Bancorp common stock 1 2 Total equity securities (a) 60-90 % 77 75 Fixed-income securities 5-25 16 14 Alternative strategies 3-11 3 6 Cash 0-13 4 5 Total 100 % 100 Includes mutual and exchange- traded funds . These reflect the targeted ranges for both the years ended December 31, 2017 and 2016 . The risk tolerance for the Plan is determined by management to be “moderate to aggressive”, recognizing that higher returns involve some volatility and that periodic declines in the portfolio’s value are tolerated in an effort to achieve real capital growth. There were no significant co ncentrations of risk associated with the investments of th e Plan at December 31, 2017 and 2016 . Permitted asset classes of the Plan include c ash and cash equivalents, fixed- income (domestic and non-U.S. bonds), equities (U.S., non-U.S., emerging mark ets and real estate investment trusts ), equipment leasing , precious metals, commod ity transactions and mortgages. The Plan utilizes derivative instruments including puts, calls, straddles or other option strategies , as approved by management. Per ERISA, th e Bancorp’s common stock cannot exceed 10% of the fair value of plan assets. Fifth Third Bank, as Trustee, is expected to manage plan assets in a manner consistent with the plan agreement and other regulatory, federal and state laws. As of December 31, 2017 and 2016 , $ 1 85 million and $ 172 million, respectively, of plan assets were managed by Fifth Third Bank. The Fifth Third Bank Pension, 401(k) and Medical Plan Committee (the “Committee”) is the plan administrator. The Trustee is required to provide to the Committee monthly and quarterly reports covering a list of plan assets, portfolio performance, transactions and asset allocation. The Trustee is also required to keep the Committee apprised of any material changes in the Trustee’s outlook and recomm ended investment policy. There were no fees paid by the Plan for investment management, accounting or administrative services provided by the Trustee. As of December 31, 2017 , there was no Bancorp common stock in Plan assets. As of December 31, 2016 , Plan assets included $ 5 million of Bancorp common stock, which was below the 10% ERISA threshold previously discussed . Plan assets are not expected to be returned to the Bancorp during 2018 . Other Information on Retirement and Benefit Plans The Bancorp has a qualified defined contribution savings plan that allows participants to make voluntary 401(k) contributions on a pre-tax or Roth basis, subject to statutory limitations. The Bancorp amended and restated the qualified defined contribution savings plan in its entirety, effective as of January 1, 2015. Beginning with the 2015 plan year, the Bancorp provides a higher company 401(k) match contribution. Expenses recognized for matching contributions to the Bancorp’s qualified defined contributio n savings plan were $ 7 9 million , $ 7 5 million and $ 71 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. The Bancorp did not make profit sharing contributions during the years ended December 31, 2017 , 2016 and 2015 . In a ddition, the Bancorp has a non-qualified defined contribution plan that allows certain employees to make voluntary contributions into a deferred compensation plan. Expenses recognized by the Bancorp for its non-qualified defined contribution plan were $ 4 m illion for the year ended December, 31 2017 and $ 3 million for both of the years ended December 31, 2016 and 2015 .

Stock-Based Compensation
Stock-Based Compensation	24 . STOCK-BASED COMPENSATION The Bancorp has histori cally emphasized employee stock ownership. The following table provides detail of the number of shares to be issued upon exercise of outstanding stock-based awards and remaining shares available for future issuance under all of the Bancorp’s equity compensation plans approved by shareholders as of December 31, 2017 : Plan Category (shares in thousands) Number of Shares to be Issued Upon Exercise Weighted-Average Exercise Price Per Share Shares Available for Future Issuance Equity compensation plans 21,687 (a) SARs (b) - (a) RSAs 2,321 - (a) RSUs 6,986 - (a) Stock options 2 $16.50 (a) PSAs (c) - (a) Employee stock purchase plan 5,653 (d) Total shares 9,309 27,340 Under the 2017 Incentive Compensation Plan, 17.5 million shares were authorized for issuance as SARs, RSAs, RSUs, stock options, performance share or unit awards, dividend or dividend equivalent rights and stock awards . The number of shares to be issued upon exercise will be determined at exercise based on the difference between the gra nt price and the market price on the date of exercise and the calculation of taxes owed on the exercise . The number of shares to be issued is dependent upon the Bancorp achieving certain predefined performance targets and ranges from zero shares to approximately 2 million shares. Represents remaining shares of Fifth Third common stock under the Bancorp’s 1993 Stock Purchase Plan, as amended and restated, including an additional 1.5 million shares approved by shareholders on March 28, 2007 and an additional 12 million shares approved by shareholders on April 21, 2009 . Stock-based awards are eligible for issuance under the Bancorp’s Incentive Compensation Plan to executives, directors and key employees of the Bancorp and its subsidiaries. The 2017 Incentive Compensation Plan was approved by shareholders on April 18, 2017 and authorized the issuance of up to 6 million shares, in addition to the 11.5 million unused shares from the 2014 Incentive Compensation Plan , as equity compensation and provides for SARs, RSAs, RSUs, stock options, performance share or unit awards, dividend or dividend equi valent rights and stock awards. Based on total stock-based awards outstanding (including SARs, RSAs, RSUs, stock options and PSA s) and shares remaining for future grants under the 20 17 Incentive Compensation Plan, the potential dilution to which the Bancorp’s shareholders of common stock are exposed due to the potential that stock-based compensation will be awarded to executives, d irectors or key employees of the Bancorp and its subsidiaries is 9%. SARs, RSAs, RSUs, stock options and PSAs outstanding represent 6% of the Bancorp’s issued shares at December 31, 2017 . All of the Bancorp’s stock-based awards are to be settled with st ock. The Bancorp has historically used treasury stock to settle stock-based awards, when available. SARs, issued at fair value based on the closing price of the Bancorp’s common stock on the date of grant, have up to ten year terms and vest and b ecome exer cisable ratably over a three or four year period of continued employment . The Bancorp does not grant discounted SARs or stock options, re-price previousl y granted SARs or stock options or grant reload stock options. RSAs and RSUs are released after three o r four years or ratably over three or four years of continued employment . RSAs include dividend and voting rights while RSUs receive dividend equivalents only . Stock options were previously issued at fair value based on the closing price of the Bancorp’s c ommon stock on the date of grant, had up to ten year terms and vested and became fully exercisable ratably over a three or four year period of continued employment. PSAs have three year cliff vesting terms with market conditions and/or performance conditio ns as defined by the plan. All of the Bancorp’s executive stock-based awards contain an annual performance hurdle of 2% return on tangible common equity. If this threshold is not met in any one of the three years during the performance period, one-third of PSAs are forfeited. Additionally, i f this threshold is not met , all SARs, RSAs and RSUs that would vest in the next year may also be forfeited at the discretion of the Human Capital and Compensation Committee of the Board of Directors. The Bancorp met thi s threshold as of December 31, 2017 . Stock-based compensation expense was $ 118 million, $ 111 million and $ 100 million for the years ended December 31, 2017 , 2016 and 2015 , r espectively, and is included in salaries, wages and incentives in the Consolidated Statements of Income. The total related income tax benefit recognized was $ 41 million, $ 39 million and $ 36 million for the years ended December 31 , 2017 , 2016 and 2015 , respectively. Stock Appreciation Rights The Bancorp uses assumptions, which are evaluated and revised as necessary, in estimating the grant-date fair value of each SAR grant. The weighted-average assumptions were as follows for the years ended December 31: 2017 2016 2015 Expected life (in years) 6 6 6 Expected volatility 37 % 37 35 Expected dividend yield 2.1 3.1 2.7 Risk-free interest rate 2.1 1.5 1.6 The expected life is generally derived from historical exercise patterns and represents the amount of time that SARs granted are expected to be outstanding. The expected volatility is based on a combination of historical and implied volatilities of the Bancorp’s common stock. The expected dividend yield is based on annual dividends divided by the Bancorp’s stock price. Annual dividends are based on projected dividends, estimated using a n expected long-term dividend payout ratio, over the estimated life of the awards. The risk-free interest rate for periods within th e contractual life of the SARs is based on the U.S. Trea sury yield curve in effect at the time of grant. The grant-date fair value of SARs is measured using the Black-Scholes option-pricing model. The weighted-average grant-date fair value of SARs granted was $ 8.55 , $ 5 . 16 and $ 5.52 per share for the years end ed December 31, 2017 , 2016 and 2015 , respectively. The total grant-date fair value of SARs that vested during the years ended December 31, 2017 , 2016 and 2015 was $ 29 million , $ 32 million and $ 35 million , respectively. At December 31, 2017 , there was $ 36 million of stock -based compensation expense related to outstanding SARs not yet recognized.

Fair Value Measurements
Fair Value Measurements	27 . 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. For more information regarding the fair value hierarchy and how the Bancorp measures fair value, refer to Note 1 . Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables summarize assets and liabilities measured at fair value on a recurring basis as of: Fair Value Measurements Using December 31, 2017 ($ in millions) Level 1 (c) Level 2 (c) Level 3 Total Fair Value Assets: Available-for-sale and other securities: U.S. Treasury and federal agencies securities $ 98 - - 98 Obligations of states and political subdivisions securities - 44 - 44 Mortgage-backed securities: Agency residential mortgage-backed securities - 15,319 - 15,319 Agency commercial mortgage-backed securities - 10,167 - 10,167 Non-agency commercial mortgage-backed securities - 3,293 - 3,293 Asset-backed securities and other debt securities - 2,218 - 2,218 Equity securities (a) 68 1 - 69 Available-for-sale and other securities (a) 166 31,042 - 31,208 Trading securities: U.S. Treasury and federal agencies securities 1 11 - 12 Obligations of states and political subdivisions securities - 22 - 22 Mortgage-backed securities: Residential mortgage-backed securities - 395 - 395 Asset-backed securities and other debt securities - 63 - 63 Equity securities 370 - - 370 Trading securities 371 491 - 862 Residential mortgage loans held for sale - 399 - 399 Residential mortgage loans (b) - - 137 137 MSRs (f) - - 858 858 Derivative assets: Interest rate contracts 1 505 8 514 Foreign exchange contracts - 124 - 124 Equity contracts - 20 - 20 Commodity contracts 39 126 - 165 Derivative assets (d) 40 775 8 823 Total assets $ 577 32,707 1,003 34,287 Liabilities: Derivative liabilities: Interest rate contracts $ 1 172 5 178 Foreign exchange contracts - 120 - 120 Equity contracts - - 137 137 Commodity contracts 38 129 - 167 Derivative liabilities (e) 39 421 142 602 Short positions (e) 25 6 - 31 Total liabilities $ 64 427 142 633 Excludes FHLB, FRB and DTCC restricted stock holdings totaling $ 248 , $ 362 and $ 2 , respectively, at December 31, 2017 .

During the year ended December 31, 2016 , no assets or liabilities were transferred between Level 1 and Level 2. Included in other assets in the Consolidated Balance Sheets. Included in other liabilities in the Consolidated Balance Sheet s. 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 U.S. Treasury securities and exchange- traded equities. If quo ted market prices are not available, then fair values are estimated using pricing models, quoted prices of securities with similar characteristics or DCFs . Level 2 securities include federal agencies securities, obligations of states and political subdivis ions securities, residential mortgage-backed securities, agency and non-agency commercial mortgage-backed securities, asset-backed securities and other debt securities and equity securities . These securities are generally valued using a market approach bas ed 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 portfol io 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 th at are valued base d 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 loan s 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 value s. For residential mortgage loans for which the fair value election has been made, and that are 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 Ma rketing d epartment, which reports to the Bancorp’s Head of the Consumer Bank , in conjunction with the Consumer Credit Risk d epartment, which reports to the Bancorp’s Chief Risk Officer, are responsible for determining the valuation methodology for resident ial mortgage loans held for inves tment. The Secondary Marketing d epartment 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 compara ble 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 l oss severities based on underlying collateral values. MSRs Effective January 1, 2017, the Bancorp elected the fair value measurement method for all existing classes of its residential mortgage servicing rights. 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, primar ily prepayment speed assumptions, OAS and weighted-average lives, resulting in a classification within Level 3 of the valuation hierarchy. Refer to Note 12 for further information on the assumptions used in the valuation of the Bancorp’s MSRs. The Sec ondary 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 quarterly that use valuation models in order to assess the reasonableness of the internal OAS model. Additionally, the Bancorp participates in peer survey s that provide additional confirmation of the reasonableness of key assumptions utilized in the MSR valuation process and the resulting MSR prices. 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 . During the years ended December 31, 2017 and 2016 , derivatives classified as Level 3, which are valued using models containing unobservable inputs, consisted primarily of a total return swap associated with the Bancor p’s sale of Visa, Inc. Class B S hares. Level 3 derivatives also include IRLCs, which utilize internally generated loan closing rate assumptions as a significant unob servable input in the valuation process. 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 S hares. 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 estimate s in excess, or shortfall, of the Banco rp’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 the fair value of the derivative liability ; conversely , a decrease in the loss estimate or an ac celeration of the resolution of the Covered Litigation would result in a decrease in the fair valu e of the derivative liability. The Accounting and Treasury d epartments , both of which report to the Bancorp’s Chief Financial Officer, determined the valuatio n 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 asset fair value of the IRLCs at December 31, 2017 was $ 8 million. I mmediate decreases in current interest rates of 25 bp s and 50 bp s would result in increases in fair value of the IRLC s of approximately $ 3 million and $ 7 million, respectively. Immediate increases of current intere st rates of 25 bp s and 50 bp s would result in decreases in fair value of the IRLC s of approximately $ 4 million and $ 8 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 $ 1 million and $ 2 million, re spectively, and the increase in fair value due to immediate 10% and 20% favorable changes in the assumed loan closing rates would be approximately $ 1 million and $ 2 million, respectively. These sensitivit ies 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 assumpti ons to the change in fair value may not be linear. The Co nsumer 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 Marketi ng, in conjuncti on 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.

These loans had fair value adjustments during the years ended December 31, 2017 and 2016 totaling $ 3 1 million and $ 30 million, respectively, and were generally based on appraisals of the underlying collateral and were, therefore, classified within Level 3 of the valuation hierarchy. Additionally, during the years ended December 31, 2017 and 2016 there were fair valu e adjustments on existing loans held for sale of an immaterial amount and $ 2 million, respectively. The fair value adjustments were also based on appraisals of the underlying collateral . The Bancorp recognized $ 2 million in losses on the sale of certain co mmercial loans held for sale during the year ended December 31, 2017 and an immaterial amount of net gains on the sale of certain commercial loans held for sale during the year ended December 31, 2016 . The Accounting department determines the procedures for the valuation of commercial loans held for sale using appraised value which may include a comparison to recently executed transactions of similar type loans. A monthly review of the portfolio is performed for reasonableness. Qua rterly, appra isals approaching a year old are updated and the Real Estate Valuation group, which reports to the Bancorp’s Chief Risk Officer, in conjunction with the Commercial Line o f Business, review the third party appraisals for reasonableness. Additionally, the Co mmercial Line of Business Finance department, which reports to the Bancorp’s Chief Financial Officer, in conjunction with the Accounting department review s all loan appraisal values, carry values and vintages. Commercial loans and leases held for investment During the years ended December 31, 2017 and 2016 , the Bancorp recorded nonrecurring impairment adjustments to certain commercial and industrial l oans, commercial mortgage loans, commercial construction loans and commercial lease s 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 curr ent 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 impair ment loss is recognized. The fair values and recognized impairment losses are reflected in the previous table s . Commercial Credit Risk, which reports to the Bancorp’s Chief Risk Officer, is responsible for preparing and reviewing the fair value estimates f or commercial loans held for investment. MSRs Effective January 1, 2017, the Bancorp elected the fair value measurement method for all existing classes of its residential mortgage servicing rights. The servicing rights were measured at fair value at Decem ber 31, 2017 and under the amortization method at December 31, 2016. Mortgage interest rates increased during the year ended December 31, 2016 and the Bancorp recognized a recovery of temporary impairment in certain classes of the MSR portfolio and the car rying value was adjusted to fair value. Refer to the MSRs section of the Assets and Liabilities Measured at Fair Value on a Recurring Basis discussion for additional information. OREO During the years ended December 31, 2017 and 2016 , the Bancorp re corded 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 were primarily due to declines in real estate values of th e properties recorded in OREO. For the years ended December 31, 2017 and 2016 , these losses include $ 4 million and $ 8 million, respectively, recorded as charge-offs, on new OREO properties transferred from loans during the respective periods and $ 6 million and $ 9 million, respectively, recorded as negative fair value adjustments on OREO in other noninterest expense in the Consolidated Statements of Income subsequent to their transfer from loans. As discussed in the following paragraphs, the fair val ue 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. T he previous tables reflect the fair value measurements of the properties before deducting the estimated costs to sell. The Re al Estate Valuation department is solely responsible for managing the appraisal process and evaluating the appraisal for comme rcial 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 in itial 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 and e quipment The Bancorp performs assessments of the recoverability of long-lived assets when events or changes in circumstances indicate that their carrying values may not be recoverable. These properties were written down to their lower of cost or market val ues. 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, resulting in a classification within Level 3 of the valuation hierarchy. Corporate Facilities, which reports to the Bancorp’s Chief Administrative Officer, in conjunction with Accounting , are responsible for preparing and reviewing the fair value estimates for bank premises and equipment . For further information on bank premise s and equipment refer to Note 7 . Operating lease equipment During the years ended December 31, 2017 and 2016 , the Bancorp recorded nonrecurring impairment adjustments to certain operating lease equipment. When evaluating whether an individu al 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 as set 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 carryi ng 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. During the years ended December 31, 2017 and 2016 , the Bancorp recorded net losses of $ 42 million and $ 9 million, respectively, as a reduction to corporate banking revenue in the Consolidated Statements of Income.

Regulatory Capital Requirements and Capital Ratios
Regulatory Capital Requirements and Capital Ratios	28 . REGULATORY CAPITAL REQUIREMENTS AND CAPIT AL RATIOS The Board of Governors of the Federal Reserve System issued capital adequacy guidelines pursuant to which it assesses the adequacy of capital in examining and supervising a BHC and in analyzing applications to it under the BHCA of 1956, as amended. These guidelines include quantitative measures that assign risk weightings to assets and off-balance sheet items, as well as define and set minimum regulatory capital requirements . The regulatory capital requirements were revised by the Basel III Final Rule whic h was effective for the Bancorp on January 1, 2015, subject to phase-in periods for certain of its components and other provisions. It established quantitative measures defining mini mum regulatory capital requirements as well as the measure of “well-capitalized ” status. Additionally, the Board of Governors of the Federal Reserve System issued similar guidelines for minimum regulatory capital requirements and “well-capitalized” measur ements for banking subsidiaries. Quarterly average assets are a component of the Tier I leverage ratio and for this purpose do not include goodwill and any other intangible assets and other investments that the FRB determines should be deducted from Tier I capital.

Business Segments
Business Segments	30 . BUSIN ESS SEGMENTS The Bancorp reports on four business segments: Commercial Banking, Branch Banking, Consumer Lending and Wealth and Asset Management . 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 . B y employing a n FTP methodology, the business segments are insulated from most benchma rk interest rate volatility, enabling them to focus on serving customers through the origination of loans and acceptance of deposits . The FTP methodology assigns charge rates and credit rates to classes of assets and liabilities, respectively, based on the estimated amount and timing of cash flows for each transaction . Assigning the FTP rate based on matching the duration of cash flows allocates interest income and interest expense to each business segment so its resulting net interest income is insulated f rom future changes in benchmark interest rates. The Bancorp’s FTP methodology also allocates the contribution to net interest income of the asset-generating and deposit-providing businesses on a duration-adjusted basis to better attribute the driver of the performance. As the asset and liability durations are not perfectly matched, the residual impact of the FTP methodology is captured in General Corporate and Other. The charge rates and credit rates are determined using the FTP rate curve, which is based o n an estimate of Fifth Third’s marginal borrowing cost in the wholesal e funding markets. The FTP curve is constructed using the U.S. swap curve, brokered CD pricing and unsecured debt pricing. The Bancorp adjusts the FTP charge rates and credit rates as di ctated by changes in interest rates for various interest-earning assets and interest-bearing liabilities and by the review of behavioral assumptions, such as prepayment rates on interest-earning assets and the estimated durations for indeterminate-lived de posits. Key assumptions, including t he credit rate s provided for deposit accounts, are reviewed annually. Credit rates for deposit products and charge rates for loan products may be reset more frequently in response to changes in market conditions. The cre dit rates for several deposit prod ucts were reset January 1, 2017 to reflect the current market rates and updated market assumptions. These rates were generally higher than those in place during 2016 , thus net interest income for deposit -providing business segments was positively impacted during 2017 . FTP charge rates on assets were affected by the prevailing level of interest rates and by the duration and repricing characteristics of the portfolio. As overall market rates increased, the FTP char ge increased for asset-generating business segments during 2017 . The Bancorp’s methodology for allocating provision for loan and lease losses expense to the business segments includes charges or benefits associated with changes in criticized commercial loan levels in addition to actual net charge-offs experienced by the loans and leases owned by each business segment. Provision for loan and lease losses expense attributable to loan and lease growth and changes in ALLL factors is captured in General Corp orate 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 operation s by accessing the capital markets as a collective unit. The following is a description of each of the Bancorp’s business s egments and the products and services they provide to their respective client bases. Commercial Banking offers credit intermediation , cash management and financial services to large and middle-market businesses and government and professional customers.

Subsequent Events [Abstract]
Subsequent Event	On January 16, 2018, Vantiv, Inc. completed its previously announced acquisition of Worldpay Group plc. with the resulting c ombined company named Worldpay, Inc. As a result of thi s transaction, the Bancorp expects to recognize a gain of approximately $ 415 million in other noninterest income in the Bancorp’s first quarter of 2018 Quarterly Report on Form 10-Q for the dilution in its ownership interest in Vantiv Holding, LLC from approximately 8.6% to approximately 4.9%. The Bancorp’s remaining interest in Vantiv Holding, LLC continues to be accounted for as an equity method in vestment given the nature of Vantiv Holding, LLC’s structure as a limited liability company and contractual arrangements between Vantiv Holding, LLC and the Bancorp. On February 8 , 2018 the Bancorp entered into an accelerated share repurchase transaction with a counterparty pursuan t to which the Bancorp paid $ 318 million on February 12, 2018 to repurchase shares of its outstanding common stock. The Bancorp is repurc hasing the shares of its common stock as part of its Board approved 100 million share repurchase program previously announced on March 1 5 , 2016. The Ba ncorp expects the settlement of the transaction to occur on or before May 14, 2018.

Summary of Significant Accounting and Reporting Policies
Nature of Operations	Nature of Operations Fifth Third Bancorp, an Ohio corporation, conducts its principal lending, deposit gathering, transaction processing and service advisory activities through its banking and non-banking subsidiaries from banking centers located throughout the Midwestern and Southeastern regions of the United States.
Basis of Presentation	Basis of Presentation The 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 e quity method of accounting and not consolidated. The investments in 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 bala nces among consolidated entities have been eliminated.
Use of Estimates	Use of Estimates 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.
Cash and Due from Banks	Cash and Due From Banks Cash and due from banks consist of currency and coin, cash items in the process of collection and due from banks. Currency and coin includes both U.S. and f oreign currency owned and held at Fifth Third offices and that is in-transit to the FRB. Cash items in the process of collection include checks and drafts that are drawn on another depository institution or the FRB that are payable immediately upon present ation in the U.S. Balances due from banks include noninterest-bearing balances that are funds on deposit at other depository institutions or the FRB.
Securities	Securities Securities are classified as held-to-maturity, available-for-sale or trading on the date of pu rchase. Only those securities which management has the intent and ability to hold to maturity are classified as held-to-maturity and reported at amortized cost. Securities are classified as available-for-sale when, in management’s judgment, they may be sol d in response to, or in anticipation of, changes in market conditions. Securities are classified as trading when bought and held principally for the purpose of selling them in the near term. Available-for-sale securities are reported at fair value with unr ealized gains and losses, net of related deferred income taxes, included in OCI. Trading securities are reported at fair value with unrealized gains and losses included in noninterest income. The fair value of a security is determined based on quoted marke t prices. If quoted market prices are not available, fair value is determined based on quoted prices of similar instruments or DCF models that incorporate market inputs and assumptions including discount rates, prepayment speeds and loss rates. Realized se curities gains or losses are reported within noninterest income in the Consolidated Statements of Income. The cost of securities sold is based on the specific identification method. Available-for-sale and held-to-maturity securities with unrealized losses are reviewed quarterly for possible OTTI. For debt securities, if the Bancorp intends to sell the debt security or will more likely than not be required to sell the debt security before recovery of the entire amortized cost basis, then an OTTI has occurred . However, even if the Bancorp does not intend to sell the debt security and will not likely be required to sell the debt security before recovery of its entire amortized cost basis, the Bancorp must evaluate expected cash flows to be received and determin e if a credit loss has occurred. In the event of a credit loss, the credit component of the impairment is recognized within noninterest income and the non-credit component is recognized through OCI. For equity securities, the Bancorp’s management evaluates the securities in an unrealized loss position in the available-for-sale portfolio for OTTI on the basis of the duration of the decline in value of the security and severity of that decline as well as the Bancorp’s intent and ability to hold these securiti es for a period of time sufficient to allow for any anticipated recovery in the market value. If it is determined that the impairment on an equity security is other-than-temporary, an impairment loss equal to the difference between the amortized cost of th e security and its fair value is recognized within noninterest income.
Basis of Presentation for Portfolio Loans and Leases	Basis of a ccounting Portfolio loans and leases are generally reported at the principal amount outstanding, net of unearned income, deferred direct loan origination fees and costs and any direct principal charge-offs. Direct loan origination fees and costs are deferred and the net amount is amortized over the estimated life of the related loans as a yield adjustment. Interest income is recognized based on the principal balance outstanding computed using the effective interest method. Loans acquired by the Bancorp through a purchase business combination are recorded at fair value as of the acquisition date. The Bancorp does not carry over the acquired compan y’s ALLL, nor does the Bancorp add to its existing ALLL as part of purchase accounting. Purchased loans are evaluated for evidence of credit deterioration at acquisition and recorded at their initial fair value. For loans acquired with no evidence of credi t deterioration, the fair value discount or premium is amortized over the contractual life of the loan as an adjustment to yield. For loans acquired with evidence of credit deterioration, the Bancorp determines at the acquisition date the excess of the loa n’s contractually required payments over all cash flows expected to be collected as an amount that should not be accreted into interest income (nonaccretable difference). The remaining amount representing the difference in the expected cash flows of acquir ed loans and the initial investment in the acquired loans is accreted into interest income over the remaining life of the loan or pool of loans (accretable yield). Subsequent to the acquisition date, increases in expected cash flows over those expected at the acquisition date are recognized prospectively as interest income over the remaining life of the loan. The present value of any decreases in expected cash flows resulting directly from a change in the contractual interest rate are recognized prospective ly as a reduction of the accretable yield. The present value of any decreases in expected cash flows after the acquisition date as a result of credit deterioration is recognized by recording an ALLL or a direct charge-off. Subsequent to the acquisition dat e, the methods utilized to estimate the required ALLL are similar to originated loans. This method of accounting for loans acquired with deteriorated cr edit quality does not apply to loans carried at fair value, residential mortgage loans held for sale and loans un der revolving credit agreements. The Bancorp’s lease portfolio consists of both direct financing and leveraged leases. Direct financing leases are carried at the aggregate of lease payments plus estimated residual value of the leased property, les s unearned income. Interest income on direct financing leases is recognized over the term of the lease to achieve a constant periodic rate of return on the outstanding investment. Leveraged leases are carried at the aggregate of lease payments (less nonrec ourse debt payments) plus estimated residual value of the leased property, less unearned income. Interest income on leveraged leases is recognized over the term of the lease to achieve a constant rate of return on the outstanding investment in the lease, n et of the related deferred income tax liability, in the years in which the net investment is positive.
Nonaccrual Loans	Nonaccrual loans and l eases When a loan is placed on nonaccrual status, the accrual of interest, amortization of loan premium, accretion of loan discount and amortization/accretion of deferred net direct loan origination fees or costs are discontinued and all previously accrued and u npaid interest is charged against income. Commercial loans are placed on nonaccrual status when there is a clear indication that the borrower’s cash flows may not be sufficient to meet payments as they become due. Such loans are also placed on nonaccrual s tatus when the principal or interest is past due 90 days or more, unless the loan is both well-secured and in the process of collection. The Bancorp classifies residential mortgage loans that have principal and interest payments that have become past due 1 50 days as nonaccrual unless the loan is both well-secured and in the process of collection. Residential mortgage loans may stay on non accrual status for an extended time as the foreclosure process typically lasts longer than 180 days. Home equity loans an d lines of credit are reported on nonaccrual status if principal or interest has been in default for 90 days or more unless the loan is both well-secured and in the process of collection. Home equity loans and lines of credit that have been in default for 60 days or more are also reported on nonaccrual status if the senior lien has been in default 120 days or more, unless the loan is both well secured and in the process of collection. Residential mortgage, home equity, automobile and other consumer loans an d leases that have been modified in a TDR and subsequently become past due 90 days are placed on nonaccrual status unless the loan is both well-secured and in the process of collection. Commercial and credit card loans that have been modified in a TDR are classified as nonaccrual unless such loans have sustained repayment performance of six months or more and are reasonably assured of repayment in accordance with the restructured terms. Well-secured loans are collateralized by perfected security interests i n real and/or personal property for which the Bancorp estimates proceeds from the sale would be sufficient to recover the outstanding principal and accrued interest balance of the loan and pay all costs to sell the collateral. The Bancorp considers a loan in the process of collection if collection efforts or legal action is proceeding and the Bancorp expects to collect funds sufficient to bring the loan current or recover the entire outstanding principal and accrued interest balance. Nonaccrual commercial l oans and nonaccrual credit card loans are generally accounted for on the cost recovery method. The Bancorp believes the cost recovery method is appropriate for nonaccrual commercial loans and nonaccrual credit card loans because the assessment of collectab ility of the remaining recorded investment of these loans involves a high degree of subjectivity and uncertainty due to the nature or absence of underlying collateral. Under the cost recovery method, any payments received are applied to reduce principal. O nce the entire recorded investment is collected, additional payments received are treated as recoveries of amounts previously charged-off until recovered in full, and any subsequent payments are treated as interest income. Nonaccrual residential mortgage l oans and other nonaccrual consumer loans are generally accounted for on the cash basis method. The Bancorp believes the cash basis method is appropriate for nonaccrual residential mortgage and other nonaccrual consumer loans because such loans have general ly been written down to estimated collateral values and the collectability of the remaining investment involves only an assessment of the fair value of the underlying collateral, which can be measured more objectively with a lesser degree of uncertainty th an assessments of typical commercial loan collateral. Under the cash basis method, interest income is recognized when cash is received, to the extent such income would have been accrued on the loan’s remaining balance at the contractual rate. Nonaccrual lo ans may be returned to accrual status when all delinquent interest and principal payments become current in accordance with the loan agreement and are reasonably assured of repayment in accordance with the contractual terms of the loan agreement, or when t he loan is both well-secured and in the process of collection. Commercial loans on nonaccrual status, including those modified in a TDR, as well as criticized commercial loans with aggregate borrower relationships exceeding $1 million, are subject to an in dividual review to identify charge-offs. The Bancorp does not have an established delinquency threshold for partially or fully charging off commercial loans. Residential mortgage loans, home equity loans and lines of credit and credit card loans that have principal and interest payments that have become past due 180 days are assessed for a charge-off to the ALLL, unless such loans are both well-secured and in the process of collection. Home equity loans and lines of credit are also assessed for charge-off t o the ALLL when such loans or lines of credit have become past due 120 days if the senior lien is also 120 days past due, unless such loans are both well-secured and in the process of collection. Automobile and other consumer loans and leases that have pri ncipal and interest payments that have become past due 120 days are assessed for a charge-off to the ALLL, unless such loans are both well-secured and in the process of collection.
Restructured Loans	Restructured loans and l eases A loan is accounted for as a TDR if the Banc orp, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower that it would not otherwise consider. A TDR typically involves a modification of terms such as a reduction of the stated interest rate or remaining principal amount of the loan, a reduction of accrued interest or an extension of the maturity date at a stated interest rate lower than the current market rate for a new loan with similar risk. In 2012, the OCC, a national bank regulatory agen cy, issued interpretive guidance that requires non-reaffirmed loans included in Chapter 7 bankruptcy filings to be accounted for as nonperforming TDRs and collateral dependent loans regardless of their payment history and capacity to pay in the future. The Bancorp’s banking subsidiary is a state chartered bank which therefore is not subject to guidance of the OCC. The Bancorp does not consider the bankruptcy court’s discharge of the borrower’s debt a concession when the discharged debt is not reaffirmed and as such, these loans are classified as TDRs only if one or more of the previously mentioned concessions are granted. The Bancorp measures the impairment loss of a TDR based on the difference between the original loan’s carrying amount and the present valu e of expected future cash flows discounted at the original, effective yield of the loan. Residential mortgage loans, home equity loans, automobile loans and other consumer loans modified as part of a TDR are maintained on accrual status, provided there is reasonable assurance of repayment and of performance according to the modified terms based upon a current, well-documented credit evaluation. Commercial loans and credit card loans modified as part of a TDR are maintained on accrual status provided there i s a sustained payment history of six months or more prior to the modification in accordance with the modified terms and collectability is reasonably assured for all remaining contractual pa yments under the modified terms . TDRs of commercial loans and credi t cards that do not have a sustained payment history of six months or more in accordance with their modified terms remain on nonaccrual status until a six month payment history is sustained. In certain cases, commercial TDRs on nonaccrual status may be acc ounted for using the cash basis method for income recognition, provided that full repayment of principal under the modified terms of the loan is reasonably assured.
Impaired Loans	Impaired loans and l eases A loan is considered to be impaired when, based on current infor mation and events, it is probable that the Bancorp will be unable to collect all amounts due (including both principal and interest) according to the contractual terms of the loan agreement. Impaired loans generally consist of nonaccrual loans and leases, loans modified in a TDR and loans over $ 1 million that are currently on accrual status and not yet modified in a TDR, but for which the Bancorp has determined that it is probable that it will grant a payment concession in the near term due to the borrower’ s financial difficulties. For loans modified in a TDR, the contractual terms of the loan agreement refer to the terms specified in the original loan agreement. A loan restructured in a TDR is no longer considered impaired in years after the restructuring i f the restructuring agreement specifies a rate equal to or greater than the rate the Bancorp was willing to accept at the time of the restructuring for a new loan with comparable risk and the loan is not impaired based on the terms specified by the restruc turing agreement. Refer to the ALLL section for discussion regarding the Bancorp’s methodology for identifying impaired loans and determination of the need for a loss accrual.
Loans Held for Sale	Loans and Leases Held for Sale Loans and leases held for sale primarily represent conforming fixed-rate residential mortgage loans originated or acquired with the intent to sell in the secondary market and jumbo residential mortgage loans, commercial loans, other residential mortgage loans and other consumer loans that managem ent has the intent to sell. Loans and leases held for sale may be carried at the lower of cost or fair value, or carried at fair value where the Bancorp has elected the fair value option of accounting under U.S. GAAP. The Bancorp has elected to measure cer tain groups of loans held for sale under the fair value option, including certain residential mortgage loans originated as held for sale and certain purchased commercial loans designated as held for sale at acquisition . For loans in which the Bancorp has n ot elected the fair value option, the lower of cost or fair value is determined at the individual loan level. The fair value of residential mortgage loans held for sale for which the fair value election has been made 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 portfo lio composition includes the effects 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. These fair value marks are recorded as a component of nonin terest income in mortgage banking net revenue. The Bancorp generally has commitments to sell residential mortgage loans held for sale in the secondary market. Gains or losses on sales are recognized in mortgage banking net revenue. Management’s intent to s ell 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 recla ssified to loans held for investment and, thereafter, reported within the Bancorp’s residential mortgage class of portfolio loans and leases. In such cases, the residential mortgage loans will continue to be measured at fair value, which is based on mortga ge-backed securities prices, interest rate risk and an internally developed credit component. Loans and leases held for sale are placed on nonaccrual status consistent with the Bancorp’s nonaccrual policy for portfolio loans and leases.
Other Real Estate Owned	Other Real Estate Owned OREO, which is included in other assets, represents property acquired through foreclosure or other proceedings and is carried at the lower of cost or fair value, less costs to sell. All OREO property is periodically evaluated for impairment and decre ases in carrying value are recognized as reductions in other noninterest income in the Consolidated Statements of Income. For government-guaranteed mortgage loans, upon foreclosure, a separate other receivable is recognized if certain conditions are met fo r the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. This receivable is also included in other assets, separate from OREO, in the Consolidated Balance Sheets.
Allowance for Loans and Leases	ALLL The Bancorp disaggregates its portfolio l oans and leases into portfolio segments for purposes of determining the ALLL. The Bancorp’s portfolio segments include commercial, residential mortgage and consumer. The Bancorp further disaggregates its portfolio segments into classes for purposes of moni toring and assessing credit quality based on certain risk characteristics. Classes within the commercial portfolio segment include commercial and industrial, commercial mortgage owner-occupied, commercial mortgage nonowner-occupied, commercial construction and commercial leasing. The residential mortgage portfolio segment is also considered a class. Classes within the consumer portfolio segment include home equity, automobile, credit card and other consumer loans and leases. For an analysis of the Bancorp’s ALLL by portfolio segment and credit quality information by class, refer to Note 6 . The Bancorp maintains the ALLL to absorb probable loan and lease losses inherent in its portfolio segments. The ALLL is maintained at a level the Bancorp considers to be adequate and is based on ongoing quarterly assessments and evaluations of the collectability and historical loss experience of loans and leases. Credit losses are charged and recoveries are credited to the ALLL. Provisions for loan and lease losses are based on the Bancorp’s review of the historical credit loss experience and such factors that, in management’s judgment, deserve consideration under existing economic conditions in estimating probable credit losses. The Bancorp’s strategy for credit risk ma nagement includes a combination of conservative exposure limits significantly below legal lending limits and conservative underwriting, documentation and collections standards. The strategy also emphasizes diversification on a geographic, industry and cust omer level, regular credit examinations and quarterly management reviews of large credit exposures and loans experiencing deterioration of credit quality. The Bancorp’s methodology for determining the ALLL is based on historical loss rates, current credit grades, specific allocation on loans modified in a TDR and impaired commercial credits above specified thresholds and other qualitative adjustments. Allowances on individual commercial loans, TDRs and historical loss rates are reviewed quarterly and adjust ed as necessary based on changing borrower and/or collateral conditions and actual collection and charge-off experience. An unallocated allowance is maintained to recognize the imprecision in estimating and measuring losses when evaluating allowances for p ools of loans. Larger commercial loans included within aggregate borrower relationship balances exceeding $ 1 million that exhibit probable or observed credit weaknesses, as well as loans that have been modified in a TDR, 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 individua l loan is impaired. Other factors may include the industry and geographic region 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. When individua l loans are impaired, allowances are determined based on management’s estimate of the borrower’s ability to repay the loan given the availability of collateral and other sources of cash flow, as well as an evaluation of legal options available to the Banco rp. Allowances for impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, fair value of the underlying collateral or readily observable secondary market values. The Bancorp eva luates the collectability of both principal and interest when assessing the need for a loss accrual. Historical credit loss rates are applied to commercial loans that are not impaired or are impaired, but smaller than the established threshold of $ 1 millio n and thus not subject to specific allowance allocations. The loss rates are derived from migration analyses for several portfolio stratifications, which track the historical net charge-off experience sustained on loans according to their internal risk gra de. The risk grading system utilized for allowance analysis purposes encompasses ten categories. Homogenous loans and leases in the residential mortgage and consumer portfolio segments are not individually risk graded. Rather, standard credit scoring syst ems and delinquency monitoring are used to assess credit risks and allowances are established based on the expected net charge-offs. Loss rates are based on the trailing twelve month net charge-off history by loan category. Historical loss rates may be adj usted for certain prescriptive and qualitative factors that, in management’s judgment, are necessary to reflect losses inherent in the portfolio. The prescriptive loss rate factors include adjustments for delinquency trends, LTV trends and refreshed FICO s core trends. The Bancorp also considers qualitative factors in determining the ALLL. These include adjustments for changes in policies or procedures in underwriting, monitoring or collections, economic conditions, portfolio mix, lending and risk management personnel, results of internal audit and quality control reviews, collateral values and geographic concentrations. The Bancorp considers home price index trends when determining the collateral value qualitative factor. The Bancorp’s primary market areas for lending are the Midw estern and Southeastern regions of the U .S. When evaluating the adequacy of allowances, consideration is given to these regional geographic concentrations and the closely associated effect changing economic conditions have on the Ba ncorp’s customers. In the current year, the Bancorp has not substantively changed any material aspect to its overall approach to determining its ALLL for any of its portfolio segments. There have been no material changes in criteria or estimation technique s as compared to prior periods that impacted the determination of the current period ALLL for any of the Bancorp’s portfolio segments.
Reserve for Unfunded Commitments	Reserve for Unfunded Commitments The reserve for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded credit facilities and is included in other liabilities in the Consolidated Balance Sheets. The determination of the adequacy of the reserve is based upon an evaluation of the unfunded c redit facilities, including an assessment of historical commitment utilization experience, credit risk grading and historical loss rates based on credit grade migration. This process takes into consideration the same risk elements that are analyzed in the determination of the adequacy of the Bancorp’s ALLL, as previously discussed. Net adjustments to the reserve for unfunded commitments are included in other noninterest expense in the Consolidated Statements of Income.
Loan Sales and Securitizations	Loan Sales and Securitizations The Bancorp periodically sells loans through either securitizations or individual loan sales in accordance with its investment policies. The sold loans are removed from the Consolidated Balance S heet and a net gain or loss is recognized in the Consolidated Financial Statements at the time of sale. The Bancorp typically isolates the loans through the use of a VIE and thus is required to assess whether the entity holding the sold or securitized loans is a VIE and whether the Bancorp is the primary beneficiary and therefore consolidator of that VIE. If the Bancorp holds the power to direct activities most significant to the economic performance of the VIE and has the obligation to absorb losses or right to receive benefits that could potentially be significant to the VIE, then the Bancorp will generally be deemed the primary beneficiary of the VIE. 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 t he equity method of accounting or other accounting standards as appropriate. Refer to Note 11 for further information on consolidated and non-consolidated VIEs. The Bancorp’s loan sales and securitizations are generally structured with servicing r etaine d, which often results in the recording of servicing rights. The Bancorp may also purchase servicing rights. Effective January 1, 2017, the Bancorp elected to prospectively adopt the fair value method for all existing classes of its residential mortgage se rvicing rights portfolio. Upon this election, all servicing rights are measured at fair value at each reporting date and changes in the fair value of servicing rights are reported in mortgage banking net revenue in the Consolidated Statements of Income in the period in which the changes occur. The election of the fair value method did not require a cumulative effect adjustment to retained earnings as there was no difference between the carrying value of the servicing rights, net of valuation allowance, and the fair value. Servicing rights are valued using internal OAS models. Key economic assumptions used in estimating the fair value of the servicing rights include the prepayment speeds of the underlying loans, the weighted-average life, the OAS spread and t he weighted-average coupon rate, as applicable. The primary risk of material changes to the value of the servicing rights resides in the potential volatility in the economic assumptions used, particularly the prepayment speeds. In order to assist in the as sessment of the fair value of servicing rights, the Bancorp obtains external valuations of the servicing rights portfolio from third parties and participates in peer surveys that provide additional confirmation of the reasonableness of the key assumptions utilized in the internal OAS model. Prior to the election of the fair value method, servicing rights were initially recorded at fair value and subsequently amortized in proportion to, and over the period of, estimated net servicing revenue. Servicing right s were tested for impairment monthly, based on fair value, with temporary impairment recognized through a valuation allowance and other-than-temporary impairment recognized through a write-off of the servicing asset and related valuation allowance. Amortiz ation and provisions for impairment of servicing rights were recorded as a component of mortgage banking net revenue in the Consolidated Statements of Income. Fees received for servicing loans owned by investors are based on a percentage of the outstandin g monthly principal balance of such loans and are included in noninterest income in the Consolidated Statements of Income as loan payments are received. Costs of servicing loans are charged to expense as incurred.
Reserve For Representation And Warranty Provisions	Reserve for Representation and Warranty P rovisions 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 gen eral, 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 m anagement 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 in vestor 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 other noninterest income at the time of sale. Updates to the reserve ar e recorded in other noninterest expense.
Legal Contingencies	Legal Contingencies The Bancorp and its subsidiaries are parties 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 and significant judgment may be required in the determination of both the probability of loss and whether the amount of the loss is reasonably estimable. The Bancorp’s estimates are subjective and are based on the status of legal and regulatory proceedings, the merit of the Bancorp’s defenses and consultation with internal and e xternal legal counsel. 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. This accrual is included in ot her liabilities in the Consolidated Balance Sheets and is adjusted from time to time as appropriate to reflect changes in circumstances. Legal expenses are recorded in other noninterest expense in the Consolidated Statements of Income.
Bank Premises and Equipment	Bank Premises and Equipment and Other Long-Lived Assets Bank premises and equipment, including leasehold improvements, are carried at cost less accumulated depreciation and amortization. Depreciation is calculated using the straight-line method based on estimated useful liv es of the assets for book purposes, while accelerated depreciation is used for income tax purposes. Amortization of leasehold improvements is computed using the straight-line method over the lives of the related leases or useful lives of the related assets , whichever is shorter. Whenever events or changes in circumstances dictate, the Bancorp tests its long-lived assets for impairment by determining whether the sum of the estimated undiscounted future cash flows attributable to a long-lived asset or asset g roup is less than the carrying amount of the long-lived asset or asset group through a probability-weighted approach. In the event the carrying amount of the long-lived asset or asset group is not recoverable, an impairment loss is measured as the amount b y which the carrying amount of the long-lived asset or asset group exceeds its fair value. Maintenance, repairs and minor improvements are charged to noninterest expense in the Conso lidated Statements of Income as incurred.
Derivative Financial Instruments	Derivative Financial Instrument s The Bancorp accounts for its derivatives as either assets or liabilities measured at fair value through adjustments to AOCI and/or current earnings, as appropriate. On the date the Bancorp enters into a derivative contract, the Bancorp designates the der ivative instrument as either a fair value hedge, cash flow hedge or as a free-standing derivative instrument. For a fair value hedge, changes in the fair value of the derivative instrument and changes in the fair value of the hedged asset or liability attr ibutable to the hedged risk are recorded in current period net income. For a cash flow hedge, changes in the fair value of the derivative instrument, to the extent that it is effective, are recorded in AOCI and subsequently reclassified to net income in th e same period(s) that the hedged transaction impacts net income. For free-standing derivative instruments, changes in fair values are reported in current period net income. Prior to entering into a hedge transaction, the Bancorp formally documents the rela tionship between the hedging instrument and the hedged item, as well as the risk management objective and strategy for undertaking the hedge transaction. This process includes linking the derivative instrument designated as a fair value or cash flow hedge to a specific asset or liability on the balance sheet or to specific forecasted transactions and the risk being hedged, along with a formal assessment at both inception of the hedge and on an ongoing basis as to the effectiveness of the derivative instrume nt in offsetting changes in fair values or cash flows of the hedged item. If it is determined that the derivative instrument is not highly effective as a hedge, hedge accounting is discontinued.
Tax Receivable Agreement Policy [Policy Text Block]	Tax Receivable Agreements In conjunction with Vantiv, Inc.’s IPO in 2012, the Bancorp entered into two TRAs with Vantiv, Inc. The TRAs provide for payments by Vantiv, Inc. to the Bancorp of 85% of the cash savings actually realized as a result of the increase in tax basis that results from the h istorical or future purchase of equity in Vantiv Holding, LLC from the Bancorp or from the exchange of equity units in Vantiv Holding, LLC for cash or Class A Stock, as well as any tax benefits attributable to payments made under the TRA. Any actual increa se in tax basis, as well as the amount and timing of any payments made under the TRA depend on a number of uncertain factors, the most significant of which is the realization of the tax benefits by Vantiv, Inc., which depends on the amount and timing of Va ntiv, Inc.’s reportable taxable income. The Bancorp accounts for these TRAs as gain contingencies and recognizes income when all uncertainties surrounding the realization of such amounts are resolved.
Income Taxes	Income Taxes The Bancorp accounts for income taxes usi ng the asset and liability method, which requires the recognition of deferred tax assets and liabilities for expected future tax consequences. Under the asset and liability method, deferred tax assets and liabilities are determined by applying the federal and state tax rates to the differences between financial statement carrying amounts and the corresponding tax bases of assets and liabilities. Deferred tax assets are also recorded for any tax attributes, such as tax credits and net operating loss carryfor wards. The net balances of deferred tax assets and liabilities are reported in other assets and accrued taxes, interest and expenses in the Consolidated Balance Sheets. Any effect of a change in federal or state tax rates on deferred tax assets and liabili ties is recognized in income tax expense in the period that includes the enactment date. The Bancorp reflects the expected amount of income tax to be paid or refunded during the year as current income tax expense or benefit. Accrued taxes represent the net expected amount due to and/or from taxing jurisdictions and are reported in accrued taxes , interest and expenses in the Consolidated Balance S heets. The Bancorp evaluates the realization of deferred tax assets based on all positive and negative evidence a vailable at the balance sheet date. Realization of deferred tax assets is based on the Bancorp’s judgment about relevant factors affecting their realization, including the taxable income within any applicable carryback periods, future projected taxable inc ome, the reversal of taxable temporary differences and tax-planning strategies. The Bancorp records a valuation allowance for deferred tax assets where the Bancorp does not believe that it is more-likely-than-not that the deferred tax assets will be realiz ed. Income tax benefits from uncertain tax positions are recognized in the financial statements only if the Bancorp believes that it is more-likely-than-not that the uncertain tax position will be sustained based solely on the technical merits of the tax position and consideration of the relevant taxing authority’s widely understood administrative practices and precedents. If the Bancorp does not believe that it is more-likely-than-not that an uncertain tax position will be sustained, the Bancorp records a liability for the uncertain tax position. If the Bancorp believes that it is more likely than not that an uncertain tax position will be sustained, the Bancorp only records a tax benefit for the portion of the uncertain tax position where the likelihood o f realization is greater than 50% upon settlement with the relevant taxing authority that has full knowledge of all relevant information. The Bancorp recognizes interest expense, interest income and penalties related to unrecognized tax benefits within cur rent income tax expense. Refer to Note 20 for further discussion regarding income taxes .
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income available to common shareholders by the weighted-average number of shares of commo n stock outstanding during the period. Earnings per diluted share is computed by dividing adjusted net income available to common shareholders by the weighted-average number of shares of common stock and common stock equivalents outstanding during the peri od. Dilutive common stock equivalents represent the exercise of dilutive stock-based awards and the dilutive effect of the settlement of outstanding forward contracts. The Bancorp calculates earnings per share pursuant to the two-class method. The two-clas s method is an earnings allocation formula that determines earnings per share separately for common stock and participating securities according to dividends declared and participation rights in undistributed earnings. For purposes of calculating earnings per share under the two-class method, restricted shares that contain nonforfeitable rights to dividends are considered participating securities until vested. While the dividends declared per share on such restricted shares are the same as dividends declare d per common share outstanding, the dividends recognized on such restricted shares may be less because dividends paid on restricted shares that are expected to be forfeited are reclassified to compensation expense during the period when forfeiture is expec ted.
Goodwill	Goodwill Business combinations entered into by the Bancorp typically include the acquisition of goodwill. Goodwill is required to be tested for impairment at the Bancorp’s reporting unit level on an annual basis, which for the Bancorp is September 30, and more frequently if events or circumstances indicate that there may b e impairment. The Bancorp has determined that its segments qualify as reporting units under U.S. GAAP. Impairment exists when a reporting unit’s carrying amount of goodwill exceeds its implied fair value. In testing goodwill for impairment, U.S. GAAP permi ts the Bancorp to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. In this qualitative assessment, the Bancorp evaluates events and circumstances whic h may include, but are not limited to, the general economic environment, banking industry and market conditions, the overall financial performance of the Bancorp, the performance of the Bancorp’s common stock, the key financial performance metrics of the B ancorp’s reporting units and events affecting the reporting units. If, after assessing the totality of events and circumstances, the Bancorp determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test would be unnecessary. However, if the Bancorp concludes otherwise or elects to bypass the qualitative assessment, it would then be required to perform the first step (Step 1) of the goodwill impairment test, an d continue to the second step (Step 2), if necessary. Step 1 of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, Step 2 of the goodwill impairment test is performed to measure the amount of impairment loss, if any. The fair value of a reporting unit is the price that would be received to sell the unit as a whole in an orderly transaction between market participants at th e measurement date. As none of the Bancorp’s reporting units are publicly traded, individual reporting unit fair value determinations cannot be directly correlated to the Bancorp’s stock price. To determine the fair value of a reporting unit, the Bancorp e mploys an income-based approach, utilizing the reporting unit’s forecasted cash flows (including a terminal value approach to estimate cash flows beyond the final year of the forecast) and the reporting unit’s estimated cost of equity as the discount rate. Additionally, the Bancorp determines its market capitalization based on the average of the closing price of the Bancorp’s stock during the month including the measurement date, incorporating an additional control premium, and compares this market-based fa ir value measurement to the aggregate fair value of the Bancorp’s reporting units in order to corroborate the results of the income approach. When required to perform Step 2, the Bancorp compares the implied fair value of a reporting unit’s goodwill with t he carrying amount of that goodwill. If the carrying amount exceeds the implied fair value, an impairment loss equal to that excess amount is recognized. A recognized impairment loss cannot exceed the carrying amount of that goodwill and cannot be reversed in future periods even if the fair value of the reporting unit subsequently recovers. During Step 2, the Bancorp determines the implied fair value of goodwill for a reporting unit by assigning the fair value of the reporting unit to all of the assets and liabilities of that unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination. The excess of the fair value of the reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill. This assignment process is only performed for purposes of testing goodwill for impairment. The Bancorp does not adjust the carrying values of recognized assets or liabilities (other than goodwill, if appropriate), nor does i t recognize previously unrecognized intangible assets in the Consolidated Financial Statements as a result of this assignment process. Refer to Note 9 for further information regarding the Bancorp’s goodwill.
Fair Value of Financial Instruments	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 participant s at the measurement date. The Bancorp employs various valuation approaches to measure fair value including the market, income and cost approach es . The market approach uses prices or relevant information generated by market transactions involving identical or comparable assets or liabilities. The income approach involves discounting future amounts to a single present amount and is based on current market expectations about those future amounts. The cost approach is based on the amount that currently would b e required to replace the service capacity of the asset. U.S. GAAP 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 prior ity 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 t hat is significant to the instrument’s fair value measurement. The three levels within the fair value hierarchy are described as follows: Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Bancorp has the ab ility to access at the measurement date. Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include: quoted prices for similar assets or liabiliti es in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 – Unobservable inputs for the asset or liability for which there is little, if any, market activity at the measurement date. Unobservable inputs reflect the Bancorp’s own assumptions about w hat market participants would use to price the asset or liability. The inputs are developed based on the best information available in the circumstances, which might include the Bancorp’s own financial data such as internally developed pricing models and D CF methodologies, as well as instruments for which the fair value determination requires significant management judgment. The Bancorp’s fair value measurements involve various valuation techniques and models, which involve inputs that are observable, when available. Valuation techniques and parameters used for measuring assets and liabilities are reviewed and validated by the Bancorp on a quarterly basis. Additionally, the Bancorp monitors the fair values of significant assets and liabilities using a varie ty of methods including the evaluation of pricing runs and exception reports based on certain analytical criteria, comparison to previous trades and overall review and assessments for reasonableness. The Bancorp may, as a practical expedient, measure the f air value of certain investments on the basis of the net asset value per share of the investment, or its equivalent. Any investments which are valued using this practical expedient are not classified in the fair value hierarchy. Refer to Note 27 for f urther information on fair value measurements.
Stock-Based Compensation	Stock-Based Compensation The Bancorp recognizes compensation expense for the grant-date fair value of stock-based awards that are expected to vest over the requisite service period. All awards, both those with cliff vesting and graded vesting, are expensed on a straight-line basis. Awards to employees that meet eligible retirement status are expensed immediately. As compensation expense is recognized, a deferred tax asset is recorded that represents an esti mate of the future tax deduction from exercise or release of restrictions. At the time awards are exercised, cancelled, expire or restrictions are released, the Bancorp recognizes an adjustment to income tax expense for the difference between the previousl y estimated tax deduction and the actual tax deduction realized. For further information on the Bancorp’s stock-based compensation plans, refer to Note 24 .
Pension Plans	Pension Plans The Bancorp uses an expected long-term rate of return applied to the fair mark et value of assets as of the beginning of the year and the expected cash flow during the year for calculating the expected investment return on all pension plan assets. Amortization of the net gain or loss resulting from experience different from that assu med and from changes in assumptions (excluding asset gains and losses not yet reflected in market-related value) is included as a component of net periodic benefit cost. If, as of the beginning of the year, that net gain or loss exceeds 10% of the greater of the projected benefit obligation and the market-related value of plan assets, the amortization is that excess divided by the average remaining service period of participating employees expected to receive benefits under the plan. The Bancorp uses a thir d-party actuary to compute the remaining service period of participating employees. This period reflects expected turnover, pre-retirement mortality and other applicable employee demographics.
Other	Other Securities and other property held by Fifth Third Wealth and Asset Management , a division of the Bancorp’s banking subsidiary, in a fiduciary or agency capacity are not included in the Consolidated Balance Sheets because such items are not assets of the subsidiaries. Wealth and asset management revenue in the C onsolidated Statements of Income is recognized on the accrual basis. Wealth and asset management service revenues are recognized monthly based on a fee charged per transaction processed and/or a fee charged on the market value of average account balances a ssociated with individual contracts. The Bancorp recognizes revenue from its card and processing services on an accrual basis as such services are performed, recording revenues net of certain costs (primarily interchange fees charged by credit card associa tions) not controlled by the Bancorp. The Bancorp purchases life insurance policies on the lives of certain directors, officers and employees and is the owner and beneficiary of the policies. The Bancorp invests in these policies, known as BOLI, to provide an efficient form of funding for long-term retirement and other employee benefits costs. The Bancorp records these BOLI policies within other assets in the Consolidated Balance Sheets at each policy’s respective cash surrender value, with changes recorded in other noninterest income in the Consolidated Statements of Income. I ntangible assets consist of core deposit intangibles, customer lists, customer relationships, non-compete agreements, trade names and rent intangibles. I ntangible assets are amortized on either a straight-line or an accelerated basis over their estimated useful lives. T he Bancorp reviews intangible assets for impairment whenever events or changes in circumstances indicate that carrying amounts may not be recoverable. Securities sold und er repurchase agreements are accounted for as secured borrowings and included in other short-term borrowings in the Consolidated Balance Sheets at the amounts at which the securities were sold plus accrued interest. Acquisitions of treasury stock are carri ed at cost. Reissuance of shares in treasury for acquisitions, exercises of stock-based awards or other corporate purposes is recorded based on the specific identification method. Advertising costs are generally expensed as incurred.
