In 2017, the Company changed its presentation of loans on the face of the Consolidated Balance Sheets to combine originated loans with purchased loans. See Note 5 - Loans for more information. The Company also changed its presentation of the Noninterest Income section on the face of the Consolidated Statements of Operations to separate card services revenue from other service charges and fee income. The difference was reclassified into miscellaneous income. Merger related expenses were reclassified from other expenses to be a separate component of the Noninterest Expense section on the Consolidated Statements of Operations. Reclassifications had no effect on prior year net income or shareholders' equity.</font></div></div>

In preparing the consolidated financial statements, management is required to make estimates and assumptions, which significantly affect the reported amounts in the consolidated financial statements. Such estimates include the valuation of loans, goodwill, intangible assets, indemnification assets, and other long-lived assets, along with assumptions used in the calculation of income taxes, among others. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. Decreased real estate values, volatile credit markets, and unemployment have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. </font></div></div>
