​ | ​ | $ | 179,717 | ​
​ The Company’s other investment securities consist of non-marketable equity securities that have no readily determinable market value. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value. As of December 31, 2023, the Company has determined that there was no impairment on its other investment securities. ​ The amortized cost and fair value of debt and equity securities at December 31, 2023 by contractual maturity are detailed below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without prepayment penalties. ​

​ Each quarter, management evaluates impairment where there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value. Management continues to monitor all of our securities with a high degree of scrutiny. There can be no assurance that we will not conclude in future periods that conditions existing at that time indicate some or all of its securities may be sold or would require a charge to earnings as a provision for credit losses in such periods. See Note 1—Summary of Significant Account Policies for further discussion. ​ ​ At December 31, 2023, investment securities with a market value of $3.0 billion and a carrying value of $3.2 billion were pledged to secure public funds deposits and for other purposes required and permitted by law (excluding securities pledged to secure repurchase agreement disclosed in Note 11 — Other Borrowings, under the “Short-Term Borrowings”, “Securities Sold Under Agreements to Repurchase (“Repurchase agreements”)” section).
