(6) Represents the weighted peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each measurement period for which a return is indicated. The peer group used for this purpose is the following published industry index: S&P 500 Banks. “Measurement period” is defined as: for 2020, the one-year period from market close on December 31, 2019 through December 31, 2020; for 2021, the two-year period from market close on December 31, 2019 through December 31, 2021; and for 2022, the three-year period from market close on December 31, 2019 through December 31, 2022. (7) The dollar amounts reported represent the amount of net income reflected in the Company’s audited financial statements for the applicable year. (8) For each applicable year, ROAA is defined as that year’s net income as a percentage of average total assets for such year. While TrustCo uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation programs, TrustCo has determined that ROAA is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used to link Compensation Actually Paid to the Company’s NEO’s, for the most recently completed fiscal year, to Company performance. | ||
