Investments in residential and commercial mortgage-backed securities represent securities issued by the Government National Mortgage Association, Federal National Mortgage Association and Federal Home Loan Mortgage Corporation. Investments in government agency securities represent securities issued by the United States Small Business Administration. Investments in corporate bonds and marketable equity securities represent positions in securities of other financial institutions. Other held to maturity investments include certificates of deposit with other financial institutions.

BancShares also holds approximately 298,000 shares of Visa Class B common stock. BancShares’ Visa Class B shares are not considered to have a readily determinable fair value and are recorded with no fair value. BancShares held FHLB stock of $51.1 million and $43.0 million and other non-marketable equity securities of $12.9 million and $12.5 million at March 31, 2020 and December 31, 2019, respectively. Both are included in other assets.

As of March 31, 2020 and January 1, 2020, no allowance for credit losses was required for available for sale and held to maturity debt securities. Accrued interest receivable on debt securities at March 31, 2020 was $22.1 million and was excluded from the estimate of credit losses. During the three months ended March 31, 2020, no accrued interest was deemed uncollectible and written off against interest income.

The following table provides the amortized cost and fair value by contractual maturity for investment securities available for sale and held to maturity. Expected maturities will differ from contractual maturities on certain securities because borrowers and issuers may have the right to call or prepay obligations with or without prepayment penalties. Repayments of mortgage-backed securities and government agency securities are dependent on the repayments of the underlying loan balances. Repayments of certain corporate bonds are subject to call provisions which can be exercised by the issuer at their discretion.

As of March 31, 2020, there were 53 investment securities available for sale that had continuous losses for more than 12 months of which 51 were government sponsored enterprise-issued mortgage-backed securities or government agency securities and two were corporate bonds.

None of the unrealized losses identified as of March 31, 2020 or December 31, 2019 relate to the marketability of the securities or the issuers’ ability to honor redemption obligations. Rather, the unrealized losses relate to changes in interest rates relative to when the investment securities were purchased, and do not indicate credit-related impairment. BancShares considered other factors including changes in credit ratings, delinquencies, and other macroeconomic factors in this determination. As a result, none of the securities were deemed to require an allowance for credit losses. BancShares has the ability and intent to retain these securities for a period of time sufficient to recover all unrealized losses.

Investment securities having an aggregate carrying value of $4.02 billion at March 31, 2020 and $3.93 billion at December 31, 2019 were pledged as collateral to secure public funds on deposit and certain short-term borrowings, and for other purposes as required by law.

Bancshares’ portfolio of held to maturity debt securities consists of mortgage-backed securities issued by government agencies and government sponsored entities. Given the consistently strong credit rating of the U.S. Treasury and the long history of no credit losses on debt securities issued by government agencies and government sponsored entities, no further credit monitoring is performed over these portfolios. Should there be downgrades to the credit rating of the U.S. Treasury or losses reported on securities issued by government agencies and government sponsored entities, Bancshares will reevaluate its determination of zero expected credit losses on held to maturity debt securities.

There were no debt securities held to maturity on nonaccrual status as of March 31, 2020.

A security is considered past due once it is 30 days contractually past due under the terms of the agreement. There were no securities past due as of March 31, 2020.
