At September 30, 2022, the Company did not have any securities held to maturity with an unrealized loss.
Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market conditions 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.
The total available for sale debt securities in loss positions at June 30, 2023, which consisted of U.S. Treasury bills and notes, agency mortgage-backed securities, agency CMOs, privately-issued CMOs, privately-issued ABS, municipal bonds and SBA certificates, had a fair value as a percentage of amortized cost of 90.4%. The municipal securities are issued by municipal governments, and are generally secured by municipal project revenues or general obligations of the municipality. The total available for sale debt securities in a loss position at September 30, 2022 had a fair value as a percentage of amortized cost of 88.9%.
The Company evaluates the existence of a potential credit loss component related to the decline in fair value of the privately issued CMO and ABS portfolios each quarter using an independent third party analysis. At June 30, 2023, the Company held four privately-issued CMO and ABS securities, acquired in a 2009 bank merger, with an aggregate amortized cost of $303,000 and fair value of $305,000 that have been downgraded to a substandard regulatory classification due to the securities credit quality rating by various rating agencies.
At June 30, 2023, two privately-issued CMO securities and one privately-issued ABS were in a loss position, and had depreciated approximately 4.67% from the Company’s carrying value and were collateralized by residential mortgage loans. These securities had a total fair value of $613,000 and a total unrealized loss of $30,000 at June 30, 2023. Based on the independent third party analysis of the expected cash flows, no other-than-temporary impairment was recognized during the three months ended June 30, 2023. An other-than temporary impairment charge of $28,000 was taken in the nine months ended June 30, 2023. While the Company does not anticipate additional credit-related impairment losses at June 30, 2023, additional deterioration in market and economic conditions may have an adverse impact on the credit quality of the portfolio, and therefore, require a credit related impairment charge in the future.
The unrealized losses on U.S. Treasury bills and notes, agency mortgage-backed securities, agency CMOs, SBA certificates and municipal bonds relate principally to changes in current interest rates for similar types of securities. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government, its agencies, or other governments, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition. As management has the intent and ability to hold debt securities to maturity, or for the foreseeable future if classified as available for sale, no declines are deemed to be other-than-temporary.
During the three and nine-month periods ended June 30, 2023, the Company recognized $341,000 of gross gains and $881,000 of gross losses on sales of available for sale securities. During the three and nine-month periods ended June 30, 2022, the Company recognized $489,000 of gross gains and $13,000 of gross losses on sales of available for sale securities.
At June 30, 2023 and September 30, 2022, available for sale debt securities with a total fair value of $56.2 million and $58.6 million, respectively, were pledged to secure FHLB borrowings.
