Management’s Discussion and Analysis of Financial Condition and Results of Operations (continued)

OVERVIEW

Fifth Third Bancorp is a diversified financial services company headquartered in Cincinnati, Ohio. At March 31,June 30, 2018, the Bancorp had $141.5$140.7 billion in assets and operated 1,1531,158 full-service banking centers and 2,4592,458 Fifth Third branded ATMs in ten states throughout the Midwestern and Southeastern regions of the U.S. The Bancorp reports on four business segments: Commercial Banking, Branch Banking, Consumer Lending and Wealth and Asset Management. The Bancorp also has an approximate 4.9%3.3% interest in Vantiv Holding, LLC. The carrying value of the Bancorp’s investment in Vantiv Holding, LLC was $632$426 million at March 31,June 30, 2018.

This overview of MD&A highlights selected information in the financial results of the Bancorp and may not contain all of the information that is important to you. For a more complete understanding of trends, events, commitments, uncertainties, liquidity, capital resources and critical accounting policies and estimates, you should carefully read this entire document as well as the Bancorp’s Annual Report on Form10-K for the year ended December 31, 2017. Each of these items could have an impact on the Bancorp’s financial condition, results of operations and cash flows. In addition, refer to the Glossary of Abbreviations and Acronyms in this report for a list of terms included as a tool for the reader of this quarterly report on Form10-Q. The abbreviations and acronyms identified therein are used throughout this MD&A, as well as the Condensed Consolidated Financial Statements and Notes to Condensed Consolidated Financial Statements.

Net interest income, net interest margin, net interest rate spread and the efficiency ratio are presented in MD&A on an FTE basis. The FTE basis adjusts for thetax-favored status of income from certain loans and securities held by the Bancorp that are not taxable for federal income tax purposes. The Bancorp believes this presentation to be the preferred industry measurement of net interest income as it provides a relevant comparison between taxable andnon-taxable amounts. The FTE basis for presenting net interest income is anon-GAAP measure. For further information, refer to theNon-GAAP Financial Measures section of MD&A.

The Bancorp’s revenues are dependent on both net interest income and noninterest income. For the three months ended March 31,June 30, 2018, net interest income on an FTE basis and noninterest income provided 52%58% and 48%42% of total revenue, respectively. For the six months ended June 30, 2018, net interest income on an FTE basis and noninterest income provided 55% and 45% of total revenue, respectively. The Bancorp derives the majority of its revenues within the U.S. from customers domiciled in the U.S. Revenue from foreign countries and external customers domiciled in foreign countries was immaterial to the Condensed Consolidated Financial Statements for both the three and six months ended March 31,June 30, 2018. Changes in interest rates, credit quality, economic trends and the capital markets are primary factors that drive the performance of the Bancorp. As discussed later in the Risk Management section of MD&A, risk identification, measurement, monitoring, control and reporting are important to the management of risk and to the financial performance and capital strength of the Bancorp.

Net interest income is the difference between interest income earned on assets such as loans, leases and securities, and interest expense incurred on liabilities such as deposits, other short-term borrowings and long-term debt. Net interest income is affected by the general level of interest rates, the relative level of short-term and long-term interest rates, changes in interest rates and changes in the amount and composition of interest-earning assets and interest-bearing liabilities. Generally, the rates of interest the Bancorp earns on its assets and pays on its liabilities are established for a period of time. The change in market interest rates over time exposes the Bancorp to interest rate risk through potential adverse changes to net interest income and financial position. The Bancorp manages this risk by continually analyzing and adjusting the composition of its assets and liabilities based on their payment streams and interest rates, the timing of their maturities and their sensitivity to changes in market interest rates. Additionally, in the ordinary course of business, the Bancorp enters into certain derivative transactions as part of its overall strategy to manage its interest rate and prepayment risks. The Bancorp is also exposed to the risk of loss on its loan and lease portfolio, as a result of changing expected cash flows caused by borrower credit events, such as loan defaults and inadequate collateral.

Noninterest income is derived from service charges on deposits, wealth and asset management revenue, corporate banking revenue, card and processing revenue, mortgage banking net revenue, net securities gains or losses and other noninterest income. Noninterest expense includes personnel costs, net occupancy expense, technology and communication costs, equipment expense, card and processing expense and other noninterest expense.

Vantiv, Inc. and Vantiv Holding, LLC Transactions

On January 16, 2018, Vantiv, Inc. completed its previously announced acquisition of Worldpay Group plc. with the resulting combined company named Worldpay, Inc. As a result of this transaction, the Bancorp recognized a gain of $414 million in other noninterest income during the first quarter of 2018 associated with the dilution in its ownership interest in Vantiv Holding, LLC from approximately 8.6% to approximately 4.9%.

On June 27, 2018, the Bancorp completed the sale of 5 million shares of Class A common stock of Worldpay, Inc., formerly Vantiv, Inc. The Bancorp had previously received these Class A shares in exchange for Class B Units of Vantiv Holding, LLC. The Bancorp recognized a gain of $205 million related to the sale. As a result of the sale, the Bancorp beneficially owns approximately 3.3% of Worldpay’s equity through its ownership of approximately 10.3 million Class B Units. The Bancorp’s remaining interest in Vantiv Holding, LLC of $632$426 million continues to be accounted for as an equity method investment given the nature of Vantiv Holding, LLC’s structure as a limited liability company and contractual arrangements between Vantiv Holding, LLC and the Bancorp.

GS Holdings Transactions

In May 2018, GreenSky, Inc. launched an IPO and issued 38 million shares of Class A common stock for a valuation of $23 per share. In connection with this IPO, the Bancorp’s investment in GreenSky, LLC, which was comprised of 252,550 membership units, was converted to 2,525,498 units of the newly formed GreenSky Holdings, LLC (“GS Holdings”), representing a 1.4% interest in GS Holdings. The Bancorp’s units in GS Holdings are exchangeable on aone-to-one basis for Class A common stock or cash after the initial180-daylock-up period expires.

Management’s Discussion and Analysis of Financial Condition and Results of Operations (continued)

At the time of the IPO, the Bancorp recognized a $16 million gain on its investment in GreenSky, LLC, which was included in other noninterest income in the Condensed Consolidated Statements of Income for the three and six months ended June 30, 2018. At June 30, 2018, the investment in GS Holdings was $53 million, which was included in equity securities in the Condensed Consolidated Balance Sheets.

Accelerated Share Repurchase Transactions

During the threesix months ended March 31,June 30, 2018, the Bancorp entered into or settled accelerated share repurchase transactions. As part of these transactions, the Bancorp entered into forward contracts in which the final number of shares delivered at settlement was based generally on a discount to the average daily volume weighted-average price of the Bancorp’s common stock during the term of the repurchase agreements. For more information on the accelerated share repurchase program, refer to Note 14 of the Notes to Condensed Consolidated Financial Statements. For a summary of the Bancorp’s accelerated share repurchase transactions that were entered into or settled during the threesix months ended March 31,June 30, 2018, refer to Table 2.

Senior Notes Offering

On March 14, 2018, the Bancorp issued and sold $650 million of 3.95% senior fixed-rate notes, with a maturity of ten years, due on March 14, 2028. These notes will be redeemable by the Bancorp, in whole or in part, on or after the date that is 30 days prior to the maturity date at a redemption price equal to 100% of the principal amount of the notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

On June 5, 2018, the Bancorp issued and sold $250 million of senior floating-rate notes, with a maturity of three years, due on June 4, 2021. Interest on the floating-rate notes is3-month LIBOR plus 47 bps. These notes will be redeemable, in whole or in part, on or after the date that is 30 days prior to the maturity date at a redemption price equal to 100% of the principal amount of the notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

2018 Branch Optimization Plan

Customer interactions and service and sales activity in Branch Banking continue to evolve with changing demographics and technology applications. Customers are increasingly utilizing digital tools to interact with their financial institutions in conducting their transactions while still utilizing physical branches for consultations and new product and service initiation. During the past three years, these developments and other business strategies led to a net decrease of 141 in the number of retail branches, or 11% of the Bancorp’s total branch count, through consolidations and sales.

The Bancorp continues to evaluate its retail network distribution in light of changes in customer behavior while developing new analytical tools that provide enhanced capabilities to optimize the profitability and growth potential of branches. In slower growth mature markets these developments enable the Bancorp to achieve efficiencies through well-executed branch consolidations without materially impacting deposit flows and/or revenue growth while maintaining the service quality standards. While continuing to evaluate such actions, the Bancorp is also focused on achieving higher retail household and deposit growth in other parts of its footprint – mainly in markets that exhibit faster economic growth and where the Bancorp has significant opportunities to capture higher market share. To that extent, based on the strategic business evaluation that was performed during the second quarter of 2018, over the next2-3 years, as part of the 2018 Branch Optimization Plan, the Bancorp plans to close between100-125 branches in more mature markets and open between100-125 new branches in higher growth markets where the Bancorp already has a strong and high performing retail branch presence. With the existing local presence and familiarity with the customer demographics, and with newly developed analytical tools, the Bancorp expects to achieve higher growth rates as a result of these actions.

As of June 30, 2018, the Bancorp had identified 29 specific branches for closure under the 2018 Branch Optimization Plan with these closures expected to be completed prior to December 31, 2018. The Bancorp expects to identify the remaining branches to be closed under the 2018 Branch Optimization Plan over the next 12 to 18 months. Additionally, the Bancorp has elected to sell 21 parcels of land which had previously been held for future branch expansion.

The adoption of the 2018 Branch Optimization Plan during the second quarter of 2018 required the Bancorp to perform assessments of the recoverability of the long-lived assets for which the Bancorp believes that it is more likely than not that the assets will be disposed of significantly before the end of their previously estimated useful lives. As a result, during the second quarter of 2018 the Bancorp recognized impairment losses of $33 million associated with these lower of cost or market adjustments in other noninterest income in the Condensed Consolidated Statements of Income. For further information about the 2018 Branch Optimization plan, refer to Note 7 of the Notes to Condensed Consolidated Financial Statements.

NON-GAAP FINANCIAL MEASURES

The following arenon-GAAP measures which provide useful insight to the reader of the Condensed Consolidated Financial Statements but should be supplemental to primary U.S. GAAP measures and should not be read in isolation or relied upon as a substitute for the primary U.S. GAAP measures.

The FTE basis adjusts for thetax-favored status of income from certain loans and securities held by the Bancorp that are not taxable for federal income tax purposes. The Bancorp believes this presentation to be the preferred industry measurement of net interest income as it provides a relevant comparison between taxable andnon-taxable amounts.

The following table reconciles thenon-GAAP financial measures of net interest income on an FTE basis, interest income on an FTE basis, net interest margin, net interest rate spread and the efficiency ratio to U.S. GAAP:

The following table reconciles thenon-GAAP financial measure of income before income taxes on an FTE basis to U.S. GAAP:

TABLE 4:Non-GAAP Financial Measure - Income Before Income Taxes on an FTE Basis    

The Bancorp believes return on average tangible common equity is an important measure for comparative purposes with other financial institutions, but is not defined under U.S. GAAP, and therefore is considered anon-GAAP financial measure. This measure is useful for evaluating the performance of a business as it calculates the return available to common shareholders without the impact of intangible assets and their related amortization.

The following table reconciles thenon-GAAP financial measure of return on average tangible common equity to U.S. GAAP for the three months ended:GAAP:

TABLE 5:4:Non-GAAP Financial Measures - Return on Average Tangible Common Equity

The Bancorp considers various measures when evaluating capital utilization and adequacy, including the tangible equity ratio and tangible common equity ratio, in addition to capital ratios defined by the U.S. banking agencies. These calculations are intended to complement the capital ratios defined by the U.S. banking agencies for both absolute and comparative purposes. Because U.S. GAAP does not include capital ratio measures, the Bancorp believes there are no comparable U.S. GAAP financial measures to these ratios. These ratios are not formally defined by U.S. GAAP or codified in the federal banking regulations and, therefore, are considered to benon-GAAP financial measures. The Bancorp encourages readers to consider its Condensed Consolidated Financial Statements in their entirety and not to rely on any single financial measure.

RECENT ACCOUNTING STANDARDS

Note 3 of the Notes to Condensed Consolidated Financial Statements provides a discussion of the significant new accounting standards applicable to the Bancorp and the expected impact of significant accounting standards issued, but not yet required to be adopted.

CRITICAL ACCOUNTING POLICIES

The Bancorp’s Condensed Consolidated Financial Statements are prepared in accordance with U.S. GAAP. Certain accounting policies require management to exercise judgment in determining methodologies, economic assumptions and estimates that may materially affect the Bancorp’s financial position, results of operations and cash flows. The Bancorp’s critical accounting policies include the accounting for the ALLL, reserve for unfunded commitments, income taxes, valuation of servicing rights, fair value measurements, goodwill and legal contingencies. These accounting policies are discussed in detail in the Critical Accounting Policies section of the Bancorp’s Annual Report on Form10-K for the year ended December 31, 2017. There have been no material changes to the valuation techniques or models during the threesix months ended March 31,June 30, 2018.

STATEMENTS OF INCOME ANALYSIS

Net Interest Income

Net interest income is the interest earned on loans and leases (including yield-related fees), securities and other short-term investments less the interest paid for core deposits (includes transaction deposits and other time deposits) and wholesale funding (includes certificates $100,000 and over, other deposits, federal funds purchased, other short-term borrowings and long-term debt). The net interest margin is calculated by dividing net interest income by average interest-earning assets. Net interest rate spread is the difference between the average yield earned on interest-earning assets and the average rate paid on interest-bearing liabilities. Net interest margin is typically greater than net interest rate spread due to the interest income earned on those assets that are funded by noninterest-bearing liabilities, or free funding, such as demand deposits or shareholders’ equity.

TableTables 6 and 7 presentspresent the components of net interest income, net interest margin and net interest rate spread for the three and six months ended March 31,June 30, 2018 and 2017, as well as the relative impact of changes in the balance sheet and changes in interest rates on net interest income. Nonaccrual loans and leases and loans and leases held for sale have been included in the average loan and lease balances. Average outstanding securities balances are based on amortized cost with any unrealized gains or losses included in other assets.

Net interest income on an FTE basis(non-GAAP) was $999 million$1.0 billion and $939 million$2.0 billion for the three and six months ended March 31,June 30, 2018, respectively, an increase of $79 million and March 31, 2017, respectively.$139 million compared to the same periods in the prior year. Net interest income was positively impacted by an increase in yields on average loans and leases of 4256 bps and an increase49 bps for the three and six months ended June 30, 2018, respectively and increases in average taxable securities of $1.3 billion for both the three and six months ended March 31,June 30, 2018 compared to the three months ended March 31, 2017.same periods in the prior year. Additionally, net interest income was positively impacted by the decisions of the FOMC to raise the target range of the federal funds rate 25 bps in June 2017, December 2017, March 2018 and MarchJune 2018. These positive impacts were partially offset by increases in the rates paid on average interest-bearing core deposits average long-term debt and average other short-term borrowings for the three months ended March 31, 2018 compared to the three months ended March 31, 2017. The rates paid on both average interest-bearing core deposits and average long-term debt increased 21 bps and the rates paid on average other short-term borrowings increased 79 bps for both the three and six months ended March 31,June 30, 2018 compared to the same periodperiods in the prior year. The rates paid on average interest-bearing core deposits increased 31 bps and 25 bps, respectively, for the three and six months ended June 30, 2018 compared to the same periods in the prior year. The rates paid on average long-term debt increased 35 bps and 27 bps for the three and six months ended June 30, 2018, respectively, compared to the same periods in the prior year.

Net interest rate spread on an FTE basis(non-GAAP) was 2.88%2.86% during both the three and six months ended March 31,June 30, 2018 compared to 2.78%2.75% and 2.77% in the same periodperiods in 2017.the prior year. Yields on average interest-earning assets increased 3444 bps and 38 bps for the three and six months ended June 30, 2018, respectively, partially offset by a 2433 bps and 29 bps increase in the rates paid on average interest-bearing liabilities for the three and six months ended March 31,June 30, 2018, respectively, compared to the three months ended March 31, 2017.same periods in the prior year.

Net interest margin on an FTE basis(non-GAAP) was 3.18%3.21% and 3.19% for the three and six months ended March 31,June 30, 2018, respectively, compared to 3.02%3.01% for both the three and six months ended March 31,June 30, 2017. The increase from March 31, 2017for both periods was driven primarily by the previously mentioned increaseincreases in the net interest rate spread partially offset by a decreasedecreases in average free funding balances. The decreasedecreases in average free funding balances wasfor both periods were driven by a decrease in average demand deposits of $1.3$2.1 billion and $1.7 billion for the three and six months ended March 31,June 30, 2018, respectively, compared to the three months ended March 31, 2017.same periods in the prior year.

Interest income on an FTE basis from loans and leases(non-GAAP) increased $96$136 million duringand $232 million for the three and six months ended March 31,June 30, 2018, respectively, compared to the three months ended March 31, 2017.same periods in the prior year. The increase wasincreases were primarily due to an increasethe aforementioned increases in yields on average commercial and industrial loans, average construction loans, average commercial mortgage loans and leases, as well as increases in the volume of average home equityother consumer loans.

Interest income from investment securities and other short-term investments increased $21$25 million duringand $45 million for the three and six months ended March 31,June 30, 2018, respectively, compared to the three months ended March 31, 2017 driven bysame periods in the prior year primarily as a result of the aforementioned increases in average taxable securities and yields on average taxable securities.

Interest expense on core deposits increased $36$56 million and $91 million for the three and six months ended March 31,June 30, 2018, respectively, compared to the three months ended March 31, 2017same periods in the prior year. The increases were primarily due to an increaseincreases in the cost of average interest-bearing core deposits to 5265 bps and 58 bps for the three and six months ended March 31,June 30, 2018, respectively, from 3134 bps and 33 bps for the three and six months ended March 31, 2017.June 30, 2017, respectively. The increaseincreases in the cost of average interest-bearing core deposits wasfor both periods were primarily due to an increaseincreases in the cost ofrates paid on average interest checking deposits and average money market deposits.
