Appendix: Non-GAAP Measures The Company’s earnings release and accompanying presentation contain certain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States (GAAP). Such non-GAAP financial information should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. However, we believe that non-GAAP reporting provides meaningful information and therefore we use it to supplement our GAAP information. We have chosen to provide this supplemental information to investors, analysts and other interested parties to enable them to perform additional analyses of operating results, to illustrate the results of operations giving effect to the non-GAAP adjustments and to provide an additional measure of performance. We believe this information is helpful in understanding the results of operations separate and apart from items that may, or could, have a disproportional positive or negative impact in any given period. For a reconciliation of the differences between the non-GAAP financial measures and the most comparable GAAP measures, please refer to the following reconciliation tables. to GAAP Reconciliation 31

Appendix: Non-GAAP to GAAP Reconciliation Net interest income and net interest margin - fully tax equivalent Three months ended Mar. 31, Dec. 31, Sep. 30, June 30, Mar. 31, 2019 2018 2018 2018 2018 Net interest income $ 121,515 $ 125,959 $ 123,485 $ 123,979 $ 75,812 Tax equivalent adjustment 1,523 1,442 1,567 1,420 718 Net interest income - tax equivalent $ 123,038 $ 127,401 $ 125,052 $ 125,399 $ 76,530 Average earning assets $ 12,163,751 $ 12,003,073 $ 12,056,627 $ 12,120,000 $ 8,087,848 Net interest margin* 4.05 % 4.16 % 4.06 % 4.10 % 3.80 % Net interest margin (fully tax equivalent)* 4.10 % 4.21 % 4.12 % 4.15 % 3.84 % * Margins are calculated using net interest income annualized divided by average earning assets. The tax equivalent adjustment to net interest income recognizes the income tax savings when comparing taxable and tax-exempt assets and assumes a 21% tax rate. Management believes that it is a standard practice in the banking industry to present net interest margin and net interest income on a fully tax equivalent basis. Therefore, management believes these measures provide useful information to investors by allowing them to make peer comparisons. Management also uses these measures to make peer comparisons.
