As of June 30, 2026, the Company's securities portfolio included 577 securities of which 517 securities were in an unrealized loss position. As of December 31, 2025, the Company's securities portfolio included 573 securities of which 491 securities were in an unrealized loss position.
In the above tables, all of the securities that were in an unrealized loss position at June 30, 2026 and December 31, 2025 are bonds that the Company has determined are in a loss position due primarily to interest rate factors and not credit quality concerns. In arriving at this conclusion, the Company reviewed third-party credit ratings and considered the severity of the impairment. The state and local government investments are comprised almost entirely of highly-rated municipal bonds issued by state and local governments throughout the nation. The Company has no significant concentrations of bond holdings from any one state or local government entity. Substantially all of the Company's mortgage-backed securities were issued by Federal Home Loan Mortgage Corporation ("FHLMC"), Federal National Mortgage Association ("FNMA"), Government National Mortgage Association ("GNMA"), or Small Business Administration ("SBA"), each of which is a government agency or GSE and guarantees the repayment of its securities. The Company does not intend to sell these securities, and it is more likely than not that the Company will not be required to sell these securities before recovery of the amortized cost.
At June 30, 2026 and December 31, 2025, the Company determined that expected credit losses associated with HTM securities were insignificant.
The book values and fair values of investment securities at June 30, 2026, by contractual maturity, are summarized in the table below. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

At June 30, 2026 and December 31, 2025, investment securities with carrying values of $885.4 million and $876.8 million, respectively, were pledged as collateral for public deposits. In addition, at June 30, 2026 and December 31, 2025, investment securities with carrying values of $616.3 million and $622.1 million, respectively, were pledged as collateral to the Federal Reserve Bank ("Federal Reserve") to secure any such borrowings.
At June 30, 2026 and December 31, 2025, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies or GSEs, in an amount greater than 10% of shareholders' equity.
There were no sales of investment securities during the three and six months ended June 30, 2026 or June 30, 2025.
Included in “Other assets” in the consolidated balance sheets are investments in Federal Home Loan Bank (“FHLB”) and Federal Reserve stock totaling $42.0 million and $41.6 million at June 30, 2026 and December 31, 2025, respectively. These investments do not have readily determinable fair values. The FHLB stock had a cost of $8.9 million and $8.5 million at June 30, 2026 and December 31, 2025, respectively, and serves as part of the collateral for the Company’s line of credit with the FHLB and is also a requirement for membership in the FHLB system. The Federal Reserve stock had a cost of $33.1 million at both June 30, 2026 and December 31, 2025, and is a requirement for Federal Reserve member bank qualification. Periodically, both the FHLB and Federal Reserve recalculate the Company’s required level of holdings, and the Company either buys more stock or redeems a portion of the stock at cost. The Company determined that neither stock was impaired at either period end.
