Reconciliation of 2017 Non-GAAP Measures to GAAP December 31 In addition to the results presented in accordance with accounting (Dollars in thousands, except per share data) 2017 principles generally accepted in the United States of America (“GAAP”), this presentation contains certain non-GAAP financial Earnings per share YTD (GAAP) $ 1.50 measures. The Company believes that providing these non-GAAP financial measures provides investors with information useful in Tax Act adjustment (GAAP ) 0.25 understanding the Company's financial performance, performance trends, and financial position. While the Company uses these non- E arnings per share YTD (non-GAAP ) $ 1.75 GAAP measures in its analysis of the Company's performance, this information should not be considered an alternative to measurements Return on assets (GAAP) 1.20% required by GAAP. Tax Act adjustment (GAAP ) 0.21% This table provides a reconciliation of certain GAAP financial Return on assets (non-GAAP ) 1.41% measures to non-GAAP financial measures. The reconciling item between the GAAP and non-GAAP financial measures was the current quarter one-time tax expense of $19.7 million. The one-time Return on tangible equity (GAAP) 11.70% tax expense was driven by the Tax Cuts and Job Act (“Tax Act”) and Tax Act adjustment (GAAP ) 1.96% the change in the current year federal marginal rate of 35 percent to 21 percent for future years, which resulted in revaluation of deferred Return on tangible equity (non-GAAP ) 13.66% tax assets and deferred tax liabilities (“net deferred tax asset”). The Company believes that the financial results are more comparable excluding the impact of the revaluation of the net deferred tax asset. 13
