PAY VERSUS PERFORMANCE

As discussed in the CD&A above, the Compensation Committee has implemented an executive compensation program designed to link a substantial portion of the NEOs’ realized compensation to the achievement of the Corporation’s financial and strategic objectives. As required by SEC rules, the following information is being presented to disclose the relationship during 2023, 2022, 2021 and 2020 between (i) executive compensation actually paid (“CAP”), as such term is defined in accordance with SEC rules, to the Corporation’s (a) CEO, and (b) our other NEOs on an average basis, and (ii) the Corporation’s financial performance. The methodology followed for calculating amounts presented in the columns “Compensation Actually Paid to CEO” and “Average Compensation Actually Paid to non-CEO NEOs,” including details of the amounts that were added to, and deducted from, the Summary Compensation Table totals to determine the CAP, are provided in the footnotes to the table. Please refer to the “Executive Compensation Disclosure – Compensation Discussion & Analysis” section in this Proxy Statement for a complete description of how executive compensation relates to the Corporation’s performance and how the Compensation Committee makes its decisions.

(b)

The Corporation’s peer group for purposes of Item 201(e) of Regulation S-K, which is the S&P Supercom Banks Index, was utilized for purposes of calculating peer group TSR for years 2023, 2022, 2021 and 2020. The TSR for both the Corporation and the peer group is based on an initial investment of $100, measured on a cumulative basis from market close on December 31, 2019, through and including the end of the fiscal year for which the TSR is being presented in the table. The TSR calculations reflect the investment of dividends.

(c)	The Corporation has identified pre-tax, pre-provision income as our Company-Selected Measure. Pre-tax, pre-provision income is a non-GAAP financial measure. See Appendix A for a reconciliation of the most directly comparable GAAP financial measure to this non-GAAP financial measure.

(d)	The CEO and the non-CEO NEOs included in this calculation for each fiscal year were as indicated in the table below:

Compensation Actually Paid vs. Total Shareholder Return

Descriptions of the Information Presented in the Pay Versus Performance Table

One of the objectives of the SEC’s “Pay Versus Performance Table” required disclosures is to illustrate the relationship between the CAP under the Corporation’s executive compensation program and certain financial performance metrics, as well as the Corporation’s TSR and the TSR of the peer group. The Corporation believes that the below information reflects an alignment of the CAP with the Corporation’s strong performance, including on the highlighted key financial performance.

The illustrations below compare CAP and the following measures:

•	The Corporation’s cumulative TSR;

•	The peer group cumulative TSR;

•	The Corporation’s Net Income; and

•	The Corporation’s Pre-Tax, Pre-Provision Income.
