In March 2022, the Company transferred 41 investment securities that were classified as AFS to HTM. The investment securities had an amortized cost basis of $361.8 million and a fair market value of $329.5 million. On the date of transfer, these securities had a total net unrealized loss of $32.3 million. There was no impact to net income as a result of the reclassification. In May 2022, the Company transferred 40 investment securities that were classified as AFS to HTM. The investment securities had an amortized cost basis of $400.9 million and a fair market value of $343.7 million. On the date of transfer, these securities had a total net unrealized loss of $57.2 million. There was no impact to net income as a result of the reclassification. During the three months ended March 31, 2023, the Company recorded a total of $1.7 million in amortization of unrecognized losses on the aforementioned investment securities transferred from AFS to HTM. As of March 31, 2023, the Company has recorded a total of $7.9 million in amortization of unrecognized losses on the aforementioned investment securities transferred from AFS to HTM. These transfers were executed to mitigate the potential future impact to capital through accumulated other comprehensive loss in consideration of a rising interest rate environment and the impact of rising rates on the market value of the investment securities. The Company believes that it maintains sufficient liquidity for future business needs and it has the positive intent and ability to hold these securities to maturity. The amortized cost, estimated fair value and weighted average yield of our HTM and AFS debt securities at March 31, 2023, by contractual maturity, are shown 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. Securities not due at a single maturity date are shown separately.

Investment securities in an unrecognized or unrealized loss position are evaluated on at least a quarterly basis, and include evaluating the changes in the investment securities' ratings issued by rating agencies and changes in the financial condition of the issuer. For mortgage-related securities, delinquency and loss information with respect to the underlying collateral, changes in levels of subordination for the Company's particular position within the repayment structure, and remaining credit enhancement as compared to projected credit losses of the security are also evaluated. The Company has evaluated its HTM and AFS investment securities that are in an unrecognized or unrealized loss position and has determined that the unrecognized or unrealized losses on the Company's investment securities are unrelated to credit quality and are primarily attributable to changes in interest rates and volatility in the financial markets since purchase. All of the investment securities in an unrecognized or unrealized loss position continue to be rated investment grade by one or more major rating agencies. As the Company does not intend to sell the HTM and AFS securities that are in an unrecognized or unrealized loss position and it is unlikely that we will be required to sell these securities before recovery of its amortized cost basis that may be at maturity, the Company has not recorded an ACL on these securities and the unrecognized or unrealized losses on these securities have not been recognized into income. Visa Class B Common Stock During the second quarter of 2022, the Company sold its 34,631 shares of Class B common stock of Visa, Inc. ("Visa") and received net proceeds of $8.5 million. As of March 31, 2023, the Company no longer owns any shares of Class B common stock of Visa. The Company received these shares in 2008 as part of Visa's initial public offering ("IPO"). These shares were transferable only under limited circumstances until they could be converted into shares of the publicly traded Class A common stock. This conversion will not occur until the resolution of certain litigation, which is indemnified by Visa members. Since its IPO, Visa has funded a litigation reserve to settle these litigation claims. At its discretion, Visa may continue to increase the litigation reserve based upon a change in the conversion ratio of each member bank’s restricted Class B common stock to unrestricted Class A common stock. Due to the existing transfer restriction and the uncertainty of the outcome of the Visa litigation, the Company determined that the Visa Class B common stock did not have a readily determinable fair value and chose to carry the shares on the Company's consolidated balance sheets at zero cost basis. As a result, the entire net proceeds of $8.5 million were recognized as a pre-tax gain and included in net gain on sales of investment securities in the Company's consolidated statements of income in 2022.
