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.

Core Return on Average Equity: Core return on average 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 intangible assets and preferred stock; (b) core net income allocable to common stockholders as net income allocable to common stockholders less net gain on acquisition, less gain(loss) on securities transactions, plus loss on debt extinguishment, plus merger expenses, plus BOLI tax expense, plus goodwill impairment, net of actual tax effect, plus amortization of intangible assets less estimated tax effect on adjustments (c) core return on average equity as core net income allocable to common stockholders (as described in clause (b)) divided by a simple average of net income and core net income plus average stockholders' equity. For return on average equity, the most directly comparable financial measure calculated in accordance with GAAP is return on average equity.

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 intangible assets and preferred stock; (b) core net income allocable to common stockholders as net income allocable to common stockholders plus goodwill impairment, net of actual tax effect, plus amortization of intangible assets less estimated tax effect on amortization of intangible assets (c) return on average tangible common equity as core 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 because it measures the return on equity, exclusive of the effects of intangible assets on earnings and capital. Goodwill and other intangible assets have the effect of increasing average stockholders’ equity and, through amortization, decreasing net income allocable to common stockholders while not increasing average tangible common equity or decreasing core net income allocable to common stockholders.

The following table reconciles, as of the dates set forth below, total average stockholders’ equity to average equity and net income allocable to common stockholders to core net income allocable to common stockholders.

Core income calculations: Core income calculations are a non-GAAP measure that management believes is an effective alternative measure of how efficiently the company utilizes its asset base. Core income is calculated by adjusting GAAP income by non-core gains and losses and excluding non-core expenses, net of tax, as outlined in the table below. We calculate (a) core net income (loss) allocable to common stockholders plus merger expenses, tax effected non-core items, goodwill impairment 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.

Core Net Income and Earnings Per Share: Core net income and Core earnings per share are non-GAAP financial measures generally used to disclose core net income from the Company's operations and earnings per share. We calculated this by taking GAAP net income less non-core impacts to net income to arrive at core net income and core diluted earnings per share. These financial measures are used by financial statement users to evaluate the core financial performance of the Company. Management believes that these measures are important to many investors who are interested in changes from period to period in the Company's financial performance and quality of earnings.

The following table reconciles as of the dates set forth below, core net income and earnings per share and compares them to GAAP net income and earnings per share.

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 goodwill impairment, merger expenses and loss on debt extinguishment, by the sum of net interest income and non-interest income, excluding net gains on the sale of available-for-sale securities and other securities transactions, and the net gain on acquisition. The GAAP-based efficiency ratio is non-interest expense less goodwill impairment, 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, loss on debt extinguishment, net gains on the sale of available-for-sale securities and other securities transactions, and the net gain on acquisition.

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