In the above tables, all of the securities that were in an unrealized loss position at March 31, 2020 and December 31, 2019 were bonds that the Company has determined are in a loss position due primarily to interest rate factors and not credit quality concerns. The Company evaluated the collectability of each of these bonds and concluded that there was no other-than-temporary impairment. The Company does not intend to sell these securities, and it is more likely than not that the Company will not be required to sell these securities before recovery of the amortized cost.

As of March 31, 2020 and December 31, 2019, the Company's security portfolio held 22 securities and 54 securities, respectively, that were in an unrealized loss position.

The book values and approximate fair values of investment securities at March 31, 2020, by contractual maturity, are summarized in the table 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.

At March 31, 2020 and December 31, 2019 investment securities with carrying values of $254,486,000 and $260,826,000, respectively, were pledged as collateral for public deposits.

Included in “other assets” in the Consolidated Balance Sheets are cost-method investments in Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank of Richmond (“FRB”) stock totaling $37,952,000 and $33,380,000 at March 31, 2020 and December 31, 2019, respectively. The FHLB stock had a cost and fair value of $20,329,000 and $15,789,000 at March 31, 2020 and December 31, 2019, respectively, and serves as part of the collateral for the Company’s line of credit with the FHLB and is also a requirement for membership in the FHLB system. The FRB stock had a cost and fair value of $17,623,000 and $17,591,000 at March 31, 2020 and December 31, 2019, respectively, and is a requirement for FRB member bank qualification. Periodically, both the FHLB and FRB recalculate the Company’s required level of holdings, and the Company either buys more stock or redeems a portion of the stock at cost. The Company determined that neither stock was impaired at either period end.

The Company owns 12,356 Class B shares of Visa, Inc. (“Visa”) stock that were received upon Visa’s initial public offering. These shares are expected to convert into Class A Visa shares subsequent to the settlement of certain litigation against Visa, to which the Company is not a party. The Class B shares have transfer restrictions, and the conversion rate into Class A shares is periodically adjusted as Visa settles litigation. The conversion rate at March 31, 2020 was approximately 1.62, which means the Company would receive approximately 20,051 Class A shares if the stock had converted on that date. This Class B stock does not have a readily determinable fair value and is carried at zero. If a readily determinable fair value becomes available for the Class B shares, or upon the conversion to Class A shares, the Company will adjust the carrying value of the stock to its market value with a credit to earnings.
