3 Non-GAAP Financial Measures This presentation contains financial information determined by methods other than in accordance with generally accepted accounting principles in the United States (“GAAP”). These non-GAAP measures include tangible book value per share and return on average tangible common equity. Management uses these non-GAAP financial measures because this information is commonly utilized by regulators and investors to evaluate financial condition, and is therefore useful to investors. These disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. A reconciliation of the non-GAAP measures, tangible book value per share and return on average tangible common equity, used in this presentation to the related GAAP measure is included in the appendix to this presentation.
