We identify certain financial measures discussed in this Quarterly Report as being “non-GAAP financial measures.” In accordance with SEC’s rules, we classify a financial measure as being a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, that are included or excluded, as the case may be, in the most directly comparable measure calculated and presented in accordance with GAAP in our statements of income, balance sheet or statements of cash flows. Non-GAAP financial measures do not include operating and other statistical measures or ratios, or statistical measures calculated using exclusively either financial measures calculated in accordance with GAAP, operating measures or other measures that are not non-GAAP financial measures or both.

The non-GAAP financial measures that we discuss in this Quarterly Report 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 way we calculate the non-GAAP financial measures that we discuss in this Quarterly Report 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 like, the non-GAAP financial measures we have discussed in this Quarterly Report when comparing such non-GAAP financial measures.

Tangible Book Value Per Common Share and Tangible Book Value Per Diluted Common Share: Tangible book value is a non-GAAP measure generally used by financial analysts and investment bankers to evaluate financial institutions. We calculate: (a) tangible common equity as total stockholders’ equity less preferred stock, goodwill, core deposit intangibles (net of accumulated amortization), and other intangible assets (net of accumulated amortization); (b) tangible book value per common share as tangible common equity (as described in clause (a)) divided by shares of common stock outstanding; and (c) tangible book value per diluted common share as tangible common equity (as described in clause (a)) divided by diluted shares of common stock outstanding. For tangible book value, the most directly comparable financial measure calculated in accordance with GAAP is book value.

Management believes that these measures are important to many investors interested in changes from period to period in book value per common share exclusive of changes in intangible assets. Goodwill and other intangible assets have the effect of increasing total book value while not increasing our tangible book value.

The following table reconciles, as of the dates set forth below, total stockholders’ equity to tangible common equity, tangible book value per common share, and tangible book value per diluted common share and compares these values with book value per common share.

Tangible Common Equity to Tangible Assets: Tangible common equity to tangible assets is a non-GAAP measure generally used by financial analysts and investment bankers to evaluate financial institutions. We calculate (a) tangible common equity as total stockholders’ equity less preferred stock, goodwill, core deposit intangibles (net of accumulated amortization), and other intangible assets (net of accumulated amortization); (b) tangible assets as total assets less goodwill, core deposit intangibles (net of accumulated amortization), and other intangible assets (net of accumulated amortization); and (c) tangible common equity to tangible assets as tangible common equity (as described in clause (a)) divided by tangible assets (as described in clause (b)). For tangible common equity to tangible assets, the most directly comparable financial measure calculated in accordance with GAAP is total stockholders’ equity to total assets.

Management believes that this measure is important to many investors in the marketplace interested in the relative changes from period to period in common equity and total assets, each exclusive of changes in intangible assets. Goodwill and other intangible assets have the effect of increasing both total stockholders’ equity and total assets while not increasing tangible common equity or tangible assets.

The following table reconciles, as of the dates set forth below, total stockholders’ equity to tangible common equity and total assets to tangible assets.

Adjusted Operating Return on Average Assets: Adjusted operating return on average assets is a non-GAAP measure generally used by financial analysts and investment bankers to evaluate financial institutions. We calculate (a) adjusted non-core items as net income (loss) allocable to common stockholders plus tax effected day one provision day one provisioning to a competed merger transaction, merger expenses, tax effected non-core items and BOLI tax adjustment, less gain (loss) from securities transactions; (b) adjusted operating net income as net income (loss) allocable to common stockholders plus adjusted non-core items, tax effected non-core items and BOLI tax adjustments.

Return on Average Tangible Common Equity: Return on average tangible common equity is a non-GAAP measure generally used by financial analysts and investment bankers to evaluate financial institutions. We calculate (a) average tangible common equity as total average stockholders’ equity less average goodwill, core deposit intangibles (net of accumulated amortization), and other intangible assets (net of accumulated amortization); (b) adjusted net income allocable to common stockholders as net income allocable to common stockholders plus intangible asset amortization (net of taxes); and (c) return on average tangible common equity as annualized adjusted net income allocable to common stockholders (as described in clause (b)) divided by average tangible common equity (as described in clause (a)). For return on average tangible common equity, the most directly comparable financial measure calculated in accordance with GAAP is return on average equity.

Management believes that this measure is important to many investors in the marketplace who are interested in earnings quality on tangible common equity. Goodwill and other intangible assets have the effect of increasing total stockholders’ equity while not increasing tangible common equity.

The following table reconciles, as of the dates set forth below, return on average stockholders’ equity and return on average tangible common equity.

Efficiency Ratio: The efficiency ratio is a non-GAAP measure generally used by financial analysts and investment bankers to evaluate financial institutions. We calculate the efficiency ratio by dividing non-interest expense, excluding merger expenses, by the sum of net interest income and non-interest income, excluding net gain on acquisition and branch sales, and net gain (loss) from securities transactions. The GAAP-based efficiency ratio is non-interest expense divided by net interest income plus non-interest income.

In management’s judgment, the adjustments made to non-interest expense and non-interest income allow investors and analysts to better assess operating expenses in relation to operating revenue by removing merger expenses, net gain (loss) from securities transactions, and net gain in acquisition and branch sales.

The following table reconciles, as of the dates set forth below, the efficiency ratio to the GAAP-based efficiency ratio.
