Non-GAAP Measures

The Company believes that the presentation of its earnings per share, return on average assets, and efficiency ratio excluding the effects of non-cash expenses for intangible asset and restricted stock amortization is a better representation of the Company’s economic reality and important to gaining an understanding of the Company’s financial performance.  Accordingly, the following table, which is a non-GAAP presentation, shows the Company’s cash earnings per share, cash returns on average assets, and cash efficiency ratios for the periods presented, along with a reconciliation to the GAAP-equivalent measure for each.
