Page 31 While average stockholders’ equity, average assets, return on average assets, and return on average stockholders’ equity are financial measures that are recorded in accordance with U.S. generally accepted accounting principles ("GAAP"), average tangible stockholders’ equity, average tangible assets, return on average tangible assets, and return on average tangible stockholders’ equity are not. Nevertheless, it is management’s belief that these non-GAAP measures should be disclosed in our SEC filings, earnings releases, and other investor communications, for the following reasons: 1. Average tangible stockholders’ equity is an important indication of the Company’s ability to grow organically and through business combinations, as well as our ability to pay dividends and to engage in various capital management strategies. 2. Returns on average tangible assets and average tangible stockholders’ equity are among the profitability measures considered by current and prospective investors, both independent of, and in comparison with, our peers. We calculate average tangible stockholders’ equity by subtracting from average stockholders’ equity the sum of our average goodwill and core deposit intangibles (“CDI”), and calculate average tangible assets by subtracting the same sum from our average assets. Average tangible stockholders’ equity, average tangible assets, and the related non-GAAP profitability measures should not be considered in isolation or as a substitute for average stockholders’ equity, average assets, or any other profitability or capital measure calculated in accordance with GAAP. Moreover, the manner in which we calculate these non-GAAP measures may differ from that of other companies reporting non-GAAP measures with similar names.

(2) To calculate our returns on average tangible assets and average tangible common stockholders’ equity for a period, we adjust the net income available to common shareholders generated during that period by adding back the amortization of CDI, net of tax, and then divide that adjusted net income by the average tangible assets and the average tangible common stockholders’ equity recorded during that time.
