APPENDIX
Unaudited Reconciliation of Non-GAAP Financial Measure

Return on average tangible equity should not be considered an alternative to return on average shareholders’ equity or other financial statement data, but rather as a non-GAAP measure of financial performance. Return on average tangible equity is computed by dividing the annualized net earnings available to common shareholders by the average tangible shareholders’ equity.

Average tangible shareholders’ equity equals average shareholders’ equity less goodwill and identifiable intangible assets. Management believes that return on average tangible equity is a meaningful measure because it reflects the equity deployed in BancorpSouth’s businesses. Because return on average tangible equity is not a measurement determined in accordance with GAAP and is susceptible to varying calculations, return on average tangible equity as presented may not be comparable to other similarly titled measures of other companies. The following table sets forth a reconciliation of return on average shareholders’ equity to return on average tangible equity:
