 enters into residential mortgage loan sale agreements with investors in the normal course of business. The Company’s practice is generally not to retain long-term fixed-rate mortgages on its balance sheet in order to mitigate interest rate risk, and consequently sells most of such mortgages into the secondary market. These agreements provide recourse to investors through certain representations concerning credit information, loan documentation, collateral and insurability. Investors request the Company to indemnify them against losses on certain loans or to repurchase loans which the investors believe do not comply with applicable representations. An increase in requests for loss indemnification can negatively impact mortgage banking revenue as additional recourse expense.  The liability for estimated losses on repurchase and indemnification claims for residential mortgage loans previously sold to investors was approximately $188,000 at December 31, 2024 and $152,000 at December 31, 2023.   

Community Banking

Through our community banking franchise, we provide banking and financial services primarily to individuals, small to mid-sized businesses, local governmental units and institutional clients residing primarily in the local areas we service. Profitability of this franchise is primarily driven by our net interest income and margin, our funding mix and related costs, the measurement of the allowance for credit losses and the impact of current and forecasted macroeconomic conditions on such measurement, the level of non-performing loans and other real estate owned, the amount of mortgage banking revenue and our history of acquiring banking operations and establishing de novo banking locations.  

Net interest income and margin. The primary source of our revenue is net interest income. Net interest income is the difference between interest income and fees on earning assets, such as loans and securities, and interest expense on liabilities to fund those assets, including deposits and other borrowings. Net interest income can change significantly from period to period based on general levels of interest rates, customer prepayment patterns, the mix of interest-earning assets and the mix of interest-bearing and non-interest-bearing deposits and borrowings.

Funding mix and related costs. The most significant source of funding in community banking is core deposits, which are comprised of non-interest-bearing deposits, non-brokered interest-bearing transaction accounts, savings deposits and domestic time deposits. Our branch network is the principal source of core deposits, which generally carry lower interest rates than wholesale funds of comparable maturities. Community banking profitability has been favorably impacted in recent years as the Company funded strong loan growth with a more desirable blend of funds. 

Measurement of the allowance for credit losses.  The Company adopted CECL as of January 1,
