Such statements involve inherent risks and uncertainties, many of which are difficult to predict and are generally beyond the control of the Company. There can be no assurance that future developments affecting the Company will be the same as those anticipated by management. The Company cautions readers that a number of important factors could cause actual results to differ materially from those expressed in, or implied or projected by, such forward-looking statements.

Non-U.S. GAAP Financial Measures Tangible common equity to tangible assets (the "tangible common equity ratio") and tangible book value per share are a non-U.S. GAAP financial measures derived from U.S. GAAP-based amounts. We calculate the tangible common equity ratio by excluding the balance of intangible assets from common stockholders' equity and dividing by tangible assets. We calculate tangible book value per share by dividing tangible common equity by common shares outstanding, as compared to book value per common share, which we calculate by dividing common stockholders’ equity by common shares outstanding. We believe that this information is consistent with the treatment by bank regulatory agencies, which exclude intangible assets from the calculation of risk-based capital ratios. Accordingly, we believe that these non-U.S. GAAP financial measures provide information that is important to investors and that is useful in understanding our capital position and ratios. However, these non-U.S. GAAP financial measures are supplemental and are not a substitute for an analysis based on U.S. GAAP measures. As other companies may use different calculations for these measures, this presentation may not be comparable to other similarly titled measures reported by other companies. A reconciliation of the non-U.S. GAAP measure of tangible common equity ratio to the U.S. GAAP measure of common equity ratio and tangible book value per share to the U.S. GAAP measure of book value per share are set forth below.

Non-U.S. GAAP Financial Measures For quarter period presented below, adjusted net income and adjusted diluted earnings per share are non-U.S. GAAP financial measures derived from U.S. GAAP-based amounts. We calculate these figures by excluding merger related expenses and DTA revaluations in the period results. Management believes that the exclusion of such items from these financial measures provides useful information to an understanding of the operating results of our core business. For the quarter period presented below, adjusted net income for return on average tangible common equity and average tangible common equity are non-U.S. GAAP financial measures derived from U.S. GAAP-based amounts. We calculate return on average tangible common equity by adjusting net income for the effect of CDI amortization and exclude the average CDI and average goodwill from the average stockholders' equity during the period. We calculate adjusted return on average tangible common equity by adjusting net income for the effect of CDI amortization and merger related expense and exclude the average CDI and average goodwill from the average stockholders' equity during the period. We believe that this is consistent with the treatment by bank regulatory agencies, which exclude intangible assets from the calculation of risk-based capital ratios.
