Compensation Actually Paid vs. Total Shareholder Return | TSR amounts reported in the graph assume an initial fixed investment of $100, and that all dividends, if any, were reinvested. |  |  |  |
Compensation Actually Paid vs. Net Income | The following graph compares (i) Compensation Actually Paid to our PEOs and the average Compensation Actually Paid to our other NEOs to (ii) our net income, for the fiscal years ended December 31, 2020, 2021, 2022, 2023 and 2024. |  |  |  |
Compensation Actually Paid vs. Company Selected Measure | The following graph compares (i) Compensation Actually Paid to our PEOs and the average Compensation Actually Paid to our other NEOs to (ii) our adjusted operating leverage, for the fiscal years ended December 31, 2020, 2021, 2022, 2023 and 2024. (1) Operating Leverage is calculated by taking the year over year percentage change in Total Revenue Before Long-Term Credit Charge minus the percentage change in Total Noninterest Expense. A positive ratio shows that revenue is growing faster than expenses. Whereas a negative ratio indicates that expenses are accumulating faster than revenue. The 2021 and 2020 ratios have been adjusted to exclude the gain on the June 30, 2020 sale of ABRC. The 2023 ratio has been adjusted to exclude a loss on a mortgage portfolio sale and investment securities losses associated with nonrecurring losses from the balance sheet repositioning announced during the fourth quarter of 2023 and expenses for certain FDIC assessments impacts. The 2024 ratio has been adjusted to exclude a loss on a mortgage portfolio sale, investment securities losses, interest income and expense for prepayment on FHLB advances with nonrecurring transactions from the balance sheet repositioning announced during the fourth quarter of 2024. See further details of these adjustments within the non-GAAP tables in Appendix B. |  |  |  |

Non-GAAP Measure Description | Operating Leverage is calculated by taking the year over year percentage change in Total Revenue Before Long-Term Credit Charge minus the percentage change in Total Noninterest Expense. A positive ratio shows that revenue is growing faster than expenses. Whereas a negative ratio indicates that expenses are accumulating faster than revenue. The 2021 and 2020 ratios have been adjusted to exclude the gain on the June 30, 2020 sale of Associated Benefits and Risk Consulting (“ABRC”). The 2023 ratio has been adjusted to exclude a loss on a mortgage portfolio sale and investment securities losses associated with nonrecurring losses from the balance sheet repositioning announced during the fourth quarter of 2023 and expense for certain FDIC assessments impacts.The 2024 ratio has been adjusted to exclude a loss on a mortgage portfolio sale, investment securities losses, interest income and expense for prepayment FHLB advances with nonrecurring transactions from the balance sheet repositioning announced during the fourth quarter of 2024. See further details of these adjustments within the non-GAAP tables in Appendix B. (6) Compensation Actually Paid includes the ASC 718 fair value of option awards. For 2023, there is a change in the methodology to determine the value of option awards, which has been updated in response to recent SEC guidance and interpretation. The change in methodology does not represent a material change in the underlying value of the option awards, and thus does not represent a material change in Compensation Actually Paid. |  |  |  |
