Note 4—Securities (continued) Certain securities have fair values less than amortized cost and, therefore, contain unrealized losses. The Company evaluated the securities which had unrealized losses for potential credit losses and determined there were none. There were 334 securities available-for-sale with unrealized losses at December 31, 2024, compared to 283 at December 31, 2023. There was one security held-to-maturity with unrealized losses at December 31, 2024 and two securities held-to-maturity with unrealized losses at December 31, 2023. In January 2025, we received payment in full for the one security held-to-maturity outstanding at December 31, 2024. There was no allowance for credit losses for held-to-maturity debt securities at December 31, 2024 or December 31, 2023. The evaluation for potential credit losses is based upon factors such as the creditworthiness of the issuers/guarantors, the underlying collateral, if applicable, and the continuing payment performance of the securities. Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security types. The Company’s held-to-maturity portfolio consisted of municipal bonds that are typically rated by major rating agencies as ‘Aa’ or better. The Company uses industry historical credit loss information adjusted for current conditions to establish an allowance for credit losses. Accrued interest receivable on securities available-for-sale and held-to-maturity totaled $4.9 million and $4.5 million at December 31, 2024 and December 31, 2023, respectively, and are excluded from the estimate of credit losses. The Company anticipates full recovery of amortized cost with respect to these securities by maturity, or sooner, in the event of a more favorable market interest rate environment. The Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell them before recovery of their amortized cost basis, which may be at maturity. The proceeds from all sales and calls of securities were available-for-sale, and the associated gains and losses for the years ended December 31, 2024, 2023, and 2022 are listed below:
|  | 2024 |  |  | 2023 |  |  | 2022 |
Proceeds |  | $ | 8,949 |  |  | $ | 163,649 |  |  | $ | 23,293 |
Gross gains |  |  | — |  |  |  | — |  |  |  | 100 |
Gross losses |  |  | 699 |  |  |  | — |  |  |  | 50 |
There were $163.6 million of sales of acquired Inland securities during the year ended December 31, 2023. The sales did not result in gains or losses given their close proximity to the acquisition date. Securities posted and pledged as collateral at December 31, 2024 and 2023 had carrying amounts of $540.0 million and $464.5 million, respectively. At December 31, 2024 and 2023, the carrying amounts of those securities pledged as collateral for public fund deposits were $471.2 mil lion and $390.3 million, respectively, and for customer repurchase agreements of $42.0 million and $47.8 million, respectively. At December 31, 2024 and 2023, there were no securities pledged for advances from the Federal Home Loan Bank. Other securities were pledged for derivative positions, letters of credit and for purposes required or permitted by law. At December 31, 2024 and 2023, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders’ equity. At December 31, 2024, the amortized cost and fair value of debt securities are shown by contractual maturity. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties.
