Securities
At June 30, 2025, total debt securities decreased $107.2 million, or 8.8% compared to December 31, 2024. The size of the Company’s securities portfolio is determined by the Company’s liquidity and asset/liability management. The net unrealized loss on debt securities available for sale, before taxes, was $23.0 million at June 30, 2025, compared to a net unrealized loss of $43.1 million at December 31, 2024. These unrealized losses of $17.6 million at June 30, 2025 and $32.9 million at December 31, 2024 are included in the Company’s stockholders’ equity as accumulated other comprehensive loss, net of income tax.

Allowance for Credit Losses
The overall credit quality of the Company's loan portfolio has remained strong. If unforeseen adverse changes occur in the national or local economy, or in the credit markets, it would be reasonable to expect that the allowance for credit losses would increase in future periods.
Nonaccrual Loans
Nonaccrual loans totaled $49.9 million at June 30, 2025 compared to $58.0 million at December 31, 2024. The Company’s nonaccrual commercial non-real estate loans made up 14% and nonaccrual commercial real estate made up 59% of nonaccrual loans. Nonaccrual loans negatively impact the Company’s net interest margin. A loan is placed on nonaccrual status when, in the opinion of management, the future collectability of both interest and principal is in serious doubt. Interest income is not recognized until the principal balance is fully collected. However, if the full collection of the remaining principal balance is not in doubt, interest income is recognized on certain of these loans on a cash basis. Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of approximately $2.3 million for the six months ended June 30, 2025 and $1.8 million for the six months ended June 30, 2024. Only a small amount of this interest is expected to be ultimately collected. Approximately $9.5 million of nonaccrual loans were guaranteed by government agencies at June 30, 2025.
The classification of a loan as nonaccrual does not necessarily indicate that loan principal and interest will ultimately be uncollectible; although, in an economic downturn, the Company’s experience has been that the level of collections decline. The above normal risk associated with nonaccrual loans has been considered in the determination of the allowance for credit losses. The level of nonaccrual loans and credit losses could rise over time as a result of adverse economic conditions.
Modified Loans
The current and future financial effects of the recorded balance of loans considered to be modified during the period were not material. The recorded balance of loans modified during the six months ended June 30, 2025 was approximately $3.6 million compared to $14.8 million during the year ended December 31, 2024.
Other Real Estate Owned and Repossessed Assets
OREO consists of properties acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure and premises held for sale. These properties are carried at the lower of the book values of the related loans or fair values based upon appraisals of the properties, less estimated costs to sell. Write-downs arising at the time of reclassification of such properties from loans to OREO are charged directly to the allowance for credit losses. Any losses on bank premises designated to be sold are charged to operating expense at the time of transfer from premises to OREO. Decreases in values of properties subsequent to their classification as OREO are charged to operating expense. During the six months ended June 30, 2025 the Company foreclosed on a construction and
