We have derived income principally from interest charged on loans and, to a lesser extent, from interest and dividends earned on investment securities. We have also derived income from noninterest sources, such as: fees received in connection with various lending and deposit services; wealth management services; mortgage loan originations, sales and servicing; and, from time to time, gains on sales of assets. Our principal expenses include interest expense on deposits and borrowings, operating expenses, such as salaries and employee benefits, occupancy and equipment expenses, data processing costs, professional fees and other noninterest expenses, provisions for credit losses and income tax expense.</span></div><div style="margin-bottom:6pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Basis of Presentation</span></div><div style="margin-bottom:12pt;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with GAAP and guidance provided by the SEC for interim financial information.

Certain reclassifications of 2023 amounts have been made to conform to the 2024 presentation. All significant transactions and accounts between subsidiaries have been eliminated.
