Government Sponsored Enterprise, Mortgage-Backed Securities: The Company owned mortgage-backed securities (“MBSs”), including collateralized mortgage obligations (“CMOs”), issued by government sponsored enterprises (“GSEs”) with an amortized cost of $396.9 million and $257.3 million and approximate fair value of $398.6 million and $265.4 million at September 30, 2021 and December 31, 2020, respectively. Unrealized losses on certain of these investments are not considered to be “other than temporary,” and the Company has the intent and ability to hold these until they mature or recover the current book value. The contractual cash flows of the investments are guaranteed by the GSEs. Accordingly, it is expected that the securities would not be settled at a price less than the amortized cost of the Company’s investment. Because 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 a recovery of its amortized cost, which may be maturity, the Company does not consider the investments to be other-than-temporarily impaired at September 30, 2021.

Non-agency Mortgage Backed Securities: The Company held private label mortgage-backed securities (“PLMBSs”), including CMOs, at September 30, 2021 with an amortized cost of $49.1 thousand and approximate fair value of $47.1 thousand. The Company held PLMBSs, including CMOs, at December 31, 2020 with an amortized cost of $57.4 thousand and approximate fair value of $54.7 thousand. Management monitors each of these securities on a quarterly basis to identify any deterioration in the credit quality, collateral values and credit support underlying the investments.

 

State and Local Governments and Other: Management monitors these securities on a quarterly basis to identify any deterioration in the credit quality. Included in the monitoring is a review of the credit rating, a financial analysis and certain demographic data on the underlying issuer. The Company does not consider these securities to be other-than-temporarily impaired at September 30, 2021.

 

The following sets forth the amortized cost and fair value of investment securities at September 30, 2021 by contractual maturity. Expected maturities differ from contractual maturities because borrowers may have the right to call or prepay the obligations with or without prepayment penalties. MBSs are based on average life at estimated prepayment speeds.
