Financial Tables Table 1 – Explanation of Non-GAAP Financial Measures In addition to results presented in accordance with GAAP, this annual report on Form 10-K includes certain  designated net interest income amounts presented on a tax-equivalent basis, a non-GAAP financial measure, including the  presentation of total revenue and the calculation of the efficiency ratio.  The Company believes the presentation of net interest income on a tax-equivalent basis provides comparability of  net interest income from both taxable and tax-exempt sources and facilitates comparability within the industry. Although the  Company believes these non-GAAP financial measures enhance investors’ understanding of its business and performance,  these non-GAAP financial measures should not be considered an alternative to GAAP. The reconciliation of these non- GAAP financial measures from GAAP to non-GAAP are presented below. 2011 2010 Fourth Third Second First Fourth Third Second First (in thousands) Quarter Quarter Quarter Quarter Quarter Quarter Quarter Quarter Net interest income (GAAP) $ 4,509 4,845 5,057 4,814 4,642 4,738 4,688 4,831 Tax-equivalent adjustment 415 429 440 435 441 449 438 437 Net interest income (Tax-equivalent) $ 4,924 5,274 5,497 5,249 5,083 5,187 5,126 5,268 (In thousands) 2011 2010 2009 2008 2007 Net interest income (GAAP) $ 19,225 18,899 18,815 17,870 15,605 Tax-equivalent adjustment 1,719 1,765 1,633 1,361 1,123 Net interest income (Tax-equivalent) $ 20,944 20,664 20,448 19,231 16,728 Year ended December 31 page 23
