5 NON-GAAP FINANCIAL MEASURES Statements included in this presentation include non-GAAP financial measures and should be read along with the accompanying tables, which provide a reconciliation of non-GAAP financial measures to GAAP financial measures. The non-GAAP financial measures used in this presentation include the following: operating noninterest income, operating noninterest expense, operating net income, adjusted earnings per diluted share, operating return on average assets, operating return on average equity, tangible book value per common share, tangible equity to tangible assets, operating efficiency ratio, operating net noninterest expense to average assets and pre-provision net revenue. The most comparable GAAP measures are noninterest income, noninterest expense, net income, diluted earnings per share, return on average assets, return on average equity, book value per common share, total equity to total assets, efficiency ratio, net noninterest expense to average assets and net interest income before provision for credit losses, respectively. Operating noninterest income excludes loss on sales of securities. Operating noninterest expense excludes severance costs, acquisition-related expenses and loss related to wire fraud incident. Operating net income, operating return on average assets, operating return on average equity and operating efficiency ratio all exclude severance costs, acquisition-related expenses, loss on sales of securities, and loss related to wire fraud incident from net income, return on average assets, return on average equity and efficiency ratio, respectively. Operating net noninterest expense to average assets ratio excludes from net noninterest expense, severance costs, acquisition-related expenses, loss on sales of securities, and loss related to wire fraud incident. Acquisition-related expenses includes fees associated with acquisitions and vendor contract buyouts. Severance costs includes costs associated with termination and retirement of employees. Adjusted earnings per diluted share includes the adjustments to operating net income. Tangible book value per common share and tangible equity to tangible assets exclude goodwill and other intangibles from book value per common share and total equity to total assets, respectively. Pre-provision net revenue is calculated by adding noninterest income to net interest income before provision for credit losses, and subtracting noninterest expense. Management uses these non-GAAP financial measures in its analysis of the Company's performance and believes these presentations provide useful supplemental information, and a clearer understanding of the Company’s performance, and if not provided would be requested by the investor community. The Company believes the non-GAAP measures enhance investors' understanding of the Company's business and performance. These measures are also useful in understanding performance trends and facilitate comparisons with the performance of other financial institutions. The limitations associated with operating measures are the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently. Non-GAAP financial measures should not be considered as an alternative to any measure of performance or financial condition as promulgated under GAAP, and investors should consider Colony Bankcorp, Inc. performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of Colony Bankcorp, Inc. Non-GAAP financial measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the results or financial condition as reported under GAAP.
