NON-GAAP FINANCIAL MEASURESThis presentation contains certain financial measures that are not measures recognized under U.S. generally accepted accounting principles (GAAP) and, therefore, are considered non-GAAP financial measures. Members of the Company’s management use these non-GAAP financial measures in their analysis of the Company’s performance, financial condition, and efficiency of operations. Management of the Company believes that these non-GAAP financial measures provide a greater understanding of ongoing operations, enhance comparability of results with prior periods, and demonstrate the effects of significant gains and charges in the current period. Management of the Company also believes that investors find these non-GAAP financial measures useful as they assist investors in understanding underlying operating performance and the analysis of ongoing operating trends. However, the non-GAAP financial measures discussed herein should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which the non-GAAP financial measures discussed herein are calculated may differ from that of other companies reporting measures with similar names. You should understand how such other banking organizations calculate their financial measures similar to, or with names similar to, the non-GAAP financial measures we have discussed herein when comparing such non-GAAP financial measures.The non-GAAP financial measures contained in this presentation include, without limitation, adjusted net income attributable to common shareholders, adjusted return on averageassets (adjusted ROAA), adjusted return on average tangible common equity (adjusted ROATCE), ROATCE, adjusted quarterly earnings per share,adjusted net interest rate spread, adjusted NIM, tangible assets, tangible common equity, tangible book value per share (TBVPS), tangible common equity to tangible assets,adjusted non-interest expense, efficiency ratio, core bank efficiency ratio, and allowance for loan losses plus unamortized loan accretion to total loans.
