The Company has evaluated its AFS investment securities that are in an unrealized loss position and has determined that the 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. Investment securities in an 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. All of the investment securities in an unrealized loss position continue to be rated investment grade by one or more major rating agencies. Because we have no intent to sell securities in an unrealized loss position and it is not more likely than not that we will be required to sell such securities before recovery of its amortized cost basis, the Company has not recorded an ACL and unrealized losses on these securities and have not been recognized into income.

Visa and MasterCard Class B Common Stock

As of September 30, 2020, the Company owns 34,631 shares of Class B common stock of Visa, Inc. ("Visa"). These shares were received in 2008 as part of Visa's initial public offering ("IPO"). These shares are transferable only under limited circumstances until they can 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 has determined that the Visa Class B common stock does not have a readily determinable fair value and chooses to carry the shares on the Company's consolidated balance sheets at zero cost basis.

During the first quarter of 2019, the Company converted the 11,170 shares of Class B common stock of MasterCard, Inc. ("MasterCard") it received during their initial public offering to an equal number of Class A common stock and sold the shares for $2.6 million. The shares were carried on the Company's consolidated balance sheets at zero cost basis and the proceeds received were recorded as a gain in other operating income - other in the Company's consolidated statements of income. The Company no longer owns any shares of MasterCard common stock.
