The Company transferred certain agency-issued securities from the available-for-sale to held-to-maturity portfolio on January 1, 2022 having a book value of approximately $320.1 million and a market value of approximately $309.7 million. As of the date of transfer, the related pre-tax net unrecognized losses of approximately $10.4 million within the accumulated other comprehensive loss balance are being amortized over the remaining term of the securities using the effective interest method. This transfer was completed after careful consideration of the Company’s intent and ability to hold these securities to maturity. Factors used in assessing the ability to hold these securities to maturity were future liquidity needs and sources of funding.

The amortized cost and fair value of investment securities as of June 30, 2022, by contractual maturity, are shown hereafter. Expected maturities may differ from contractual maturities for certain investments because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. This is often the case with mortgage-backed securities,

which are disclosed separately in the table below.

Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.

At June 30, 2022, there were 369 available-for-sale securities and 77 held-to-maturity securities that had unrealized losses. These securities are guaranteed by either the U.S. Government, other governments or U.S. corporations. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred and the results of reviews of the issuer’s financial condition. The unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying securities were purchased. As management has the ability to hold debt securities until maturity, or for the foreseeable future if classified as available-for-sale, no declines are deemed to be other than temporary.
