Accrued interest receivable on available-for-sale debt securities, included in the "Accrued Interest Receivable" line item on the Company's Consolidated Balance Sheets, amounted to $3.2 million at March 31, 2025 and $2.7 million at December 31, 2024.

At March 31, 2025, management performed its quarterly analysis of all securities with unrealized losses and concluded that the unrealized losses resulted from significant increases in market interest rates relative to the book yield on the securities held. Management concluded that no ACL for available-for-sale securities was necessary as of March 31, 2025 and anticipates they will mature or be called at par value. The Company does not intend to sell these investments prior to maturity and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell each security before the recovery of its amortized cost basis.
The following tables summarize the duration of unrealized losses for debt securities at March 31, 2025 and December 31, 2024:

The scheduled contractual maturities shown above may not reflect the actual maturities of the investments. The actual MBS/CMO cash flows likely will be faster than presented above due to prepayments and amortization. Similarly, included in the table above are callable securities, comprised of municipal securities and corporate bonds, with a fair value of $130.5 million, which can be redeemed by the issuers prior to the maturity presented above. Management considers these factors when evaluating the interest-rate risk in the Company's asset-liability management program.

From time to time, the Company may pledge debt securities as collateral for deposit account balances of municipal customers, and for borrowing capacity with the FHLB and the FRB. The fair value of debt securities pledged as collateral for these purposes was $585.9 million and $575.2 million at March 31, 2025 and December 31, 2024, respectively.

There were no sales of debt securities for the three months ended March 31, 2025 and March 31, 2024.

At December 31, 2024, the Company held equity securities with a fair value of $9.7 million, which consisted of $6.3 million in management directed investments and $3.4 million in mutual funds held in conjunction with the Company's supplemental executive retirement and deferred compensation plan.
