Retirement Benefits [Abstract] |
Retirement and Benefit Plans | Retirement and Benefit Plans The Bancorp acquired various retirement and employee benefit plans in connection with the acquisition of Comerica Incorporated, which was completed on February 1, 2026. These plans provide retirement, health care and life insurance benefits to eligible employees and retirees and include both qualified and non‑qualified defined benefit arrangements. For information on the Bancorp’s previously existing plans, refer to Note 22 of the Notes to Consolidated Financial Statements included in the Bancorp’s Annual Report on Form 10-K for the year ended December 31, 2025. The Bancorp recognizes the overfunded or underfunded status of the plans in other assets and accrued taxes, interest and expenses, respectively, in the Condensed Consolidated Balance Sheets. The following sections provide further information regarding the defined benefit pension and postretirement benefit obligations, plan structures and funding practices for these plans. The following table presents the components of the Bancorp’s net periodic pension (benefit) expense, which includes the effects of the plans acquired from Comerica on February 1, 2026:
($ in millions) | For the three months ended June 30, 2026 | For the six months ended June 30, 2026 |
Service cost(a) | $ | 10 |  | 17 |  |
Other components of net periodic pension (benefit) expense: |  |  |
Interest cost | 24 |  | 42 |  |
Expected return on plan assets | (50) |  | (83) |  |
Amortization of net actuarial losses | 1 |  | 1 |  |
Curtailment gain | (6) |  | (6) |  |
Retirement termination benefits | — |  | 11 |  |
Total other components of net periodic pension benefit(b) | $ | (31) |  | (35) |  |
Net periodic pension benefit | $ | (21) |  | (18) |  |
(a)Included in compensation and benefits expense in the Condensed Consolidated Statements of Income. (b)Included in other noninterest expense in the Condensed Consolidated Statements of Income. Net periodic pension benefit for both the three and six months ended June 30, 2026 included a $6 million gain related to a curtailment associated with a reduction in plan participants as a result of position eliminations in connection with the Comerica acquisition. Additionally, other net periodic pension benefit for the six months ended June 30, 2026 included $11 million of expense related to retirement termination benefits associated with former employees of Comerica. Comerica Defined Benefit Retirement Plans The Bancorp acquired both a qualified and non-qualified defined benefit retirement plan in connection with the Comerica acquisition. Plan participants primarily include individuals who were previously employed by Comerica or its subsidiaries prior to the acquisition. These plans primarily utilize a cash balance benefit structure which vests after three years of service, with additional benefits available for certain individuals who were participants in the plan prior to 2017. Benefits earned under the cash balance formula include contribution credits, which are based on eligible compensation, age and years of service, and interest credits which are based on U.S. Treasury securities. The benefit structure of the non-qualified plan is similar to the qualified plan except that the non-qualified plan considers compensation in excess of applicable IRS limitations. The assets and obligations of these acquired defined benefit plans were remeasured as of June 30, 2026 in connection with the curtailment. The following table summarizes the acquired plans:
As of June 30, 2026 ($ in millions) | Qualified Plan | Non-Qualified Plan |
Fair value of plan assets | $ | 3,040 |  | — |  |
Projected benefit obligation | 1,574 |  | 152 |  |
Accumulated benefit obligation | 1,557 |  | 149 |  |
Funded status(a) | $ | 1,466 |  | (152) |  |
(a)Based on projected benefit obligation. Weighted-Average Assumptions The plans’ actuarial assumptions were evaluated as of June 30, 2026 in connection with the curtailment remeasurement and will be updated annually and as necessary thereafter. The expected long-term rate of return on plan assets is the average rate of return expected to be realized on funds invested or expected to be invested over the life of the plan. The expected long-term rate of return on plan assets is set after considering both long-term returns in the general market and long-term returns experienced by the assets in the plan. The returns on the various asset categories are blended to derive an equity and a fixed income long-term rate of return. The following table summarizes the weighted-average plan assumptions:
As of June 30, 2026 | Qualified Plan | Non-Qualified Plan |
Discount rate | 5.79 |  | % | 5.75 |  |
Rate of compensation increase | 4.50 |  |  | 4.50 |  |
Interest crediting rate | 4.87-5.25 |  | 4.87-5.25 |
Expected long-term return on plan assets | 6.75 |  |  | N/A |
Estimated future benefit payments The Bancorp did not make contributions to the plans during the period from February 1, 2026 to June 30, 2026, and, based on actuarial assumptions, does not expect to make contributions to the plans for the remainder of 2026, except to the extent necessary for benefit payments made under the Non-Qualified Plan. The following table summarizes the estimated future benefit payments:
As of June 30, 2026 ($ in millions) | Qualified Plan | Non-Qualified Plan |
Remainder of 2026 | $ | 227 |  | 18 |  |
2027 | 144 |  | 15 |  |
2028 | 140 |  | 15 |  |
2029 | 140 |  | 15 |  |
2030 | 139 |  | 14 |  |
2031 - 2035 | 643 |  | 67 |  |
Fair Value Measurements of Plan Assets The following table summarizes the Qualified Plan assets measured at fair value on a recurring basis:

Investments measured at NAV: |  |  |  |  |  |  |
Collective investment funds |  |  |  |  |  |  | $ | 1,336 |
Total plan assets at fair value(c) |  |  |  |  |  |  | $ | 3,021 |
(a)For further information on fair value hierarchy levels, refer to Note 1 of the Notes to Consolidated Financial Statements included in the Bancorp’s Annual Report on Form 10-K for the year ended December 31, 2025. (b)Includes corporate and municipal bonds and notes. (c)Excludes accrued interest receivable of $19. 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. 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, then fair values are estimated using pricing models which primarily utilize quoted prices of securities with similar characteristics. Level 2 securities may include federal agencies securities, asset-backed securities and other debt securities and private placement securities. Collective investment funds NAV is used as a practical expedient to determine the fair value of investments in collective funds, so these investments are not classified within the fair value hierarchy. There are no unfunded commitments or redemption restrictions on the collective investment funds. The investments are redeemable daily. There were no assets in the Non-Qualified Plan at June 30, 2026. Investment Policies and Strategies The Bancorp’s objectives for the Qualified Plan are to maintain a portfolio of assets of appropriate liquidity and diversification; to generate investment returns (net of all operating costs) that are reasonably anticipated to maintain the plan’s fully funded status or to reduce a funding deficit, after taking into account various factors, including reasonably anticipated future contributions, expense and the interest rate sensitivity of the plan’s assets relative to that of the plan’s liabilities; and to generate investment returns (net of all operating costs) that meet or exceed a customized benchmark as defined in the plan’s investment policy. The Bancorp’s target allocations for plan investments are 55 percent to 65 percent for fixed-income securities and 35 percent to 45 percent for equity securities. There were no significant concentrations of risk associated with the investments of the Qualified Plan at June 30, 2026. Permitted asset classes of the Qualified Plan include fixed-income (U.S. Treasury and other U.S. government agency securities, corporate bonds and notes, municipal bonds, collateralized mortgage obligations and money market funds) and equities (collective investment funds). Derivative instruments are permissible for hedging and transactional efficiency, but only to the extent that the derivative use enhances the efficient execution of the Qualified Plan’s investment policy. The Qualified Plan does not directly invest in securities issued by the Bancorp and its subsidiaries. Fifth Third Bank, National Association, (the “Trustee”), is expected to manage plan assets in a manner consistent with the Qualified Plan agreement and other regulatory, federal and state laws. The Fifth Third Bank Pension, 401(k) and Medical Plan Committee (the “Committee”) is the plan administrator. The Trustee provides to the Committee quarterly reports and is also required to keep the Committee apprised of any material changes in the Trustee’s outlook and recommended investment policy. There were no fees paid by the Plan for accounting or administrative services provided by the Trustee for the period from February 1, 2026 to June 30, 2026. Comerica Postretirement Benefit Plan The Bancorp also acquired a postretirement benefit plan in connection with the Comerica acquisition, which provides postretirement health care and life insurance benefits for certain former Comerica employees. This plan is frozen and has been closed to new participants since January 1, 2007 but primarily provides benefits to participants who retired prior to January 1, 2000. The Plan’s health benefits are structured as a funded Health Reimbursement Arrangement for participants covered by Medicare or individual marketplace insurance plans. At February 1, 2026, the plan’s accumulated benefit obligation was $13 million and the plan was overfunded.
