Appendix

Non - GAAP Financial Measures Tangible common equity, tangible assets and tangible book value per common share are financial measures not recognized in generally accepted accounting principles ("GAAP"). Our management, banking regulators, many financial analysts and other investors use these non - GAAP financial measures to compare the capital adequacy of banking organizations with significant amounts of preferred equity and/or goodwill or other intangible assets, which typically stem from the use of the purchase accounting method of accounting for mergers and acquisitions. Tangible common equity, tangible assets, tangible book value per share or related measures should not be considered as a substitute for total shareholders' equity, total assets, book value per share or any other measure calculated in accordance with GAAP. Moreover , the manner in which we calculate these measures may differ from those of other companies reporting measures with similar names. The following table reconciles these non - GAAP performance measures and a capital ratio using such measures to the most directly comparable GAAP measure or ratio.
