Appendix 13

Non-GAAP Financial Measures Tangible common equity and tangible book value per share are non-GAAP financial measures derived from GAAP-based amounts. We calculate tangible common equity by excluding the balance of intangible assets from common stockholders’ equity. We calculate tangible book value per share by dividing tangible common equity by common shares outstanding, as compared to book value per common share, which we calculate by dividing common stockholders’ equity by common shares outstanding. We believe that this is consistent with the treatment by bank regulatory agencies, which exclude intangible assets from the calculation of risk-based capital ratios. Accordingly, we believe that these non-GAAP financial measures provide information that is important to investors and that is useful in understanding our capital position and ratios. However, these non-GAAP financial measures are supplemental and are not a substitute for an analysis based on GAAP measures. As other companies may use different calculations for these measures, this presentation may not be comparable to other similarly titled measures reported by other companies. A reconciliation of the non-GAAP measures of tangible common equity and tangible book value per share to the GAAP measures of common stockholders’ equity and book value per share is set forth.
