Note 2: Securities

The amortized cost and estimated fair value of debt securities at December 31, 2022 and 2021, by contractual maturity, are shown below. Maturities may differ from contractual maturities in mortgage-backed securities because the mortgages underlying the securities may be called or repaid without any penalties, therefore, these securities have been included in 1 to 5 years based on average remaining life.

As of December 31, 2022 and 2021, no securities were pledged to secure public deposits or for other purposes as required or permitted by law. At December 31, 2022 and 2021, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of equity. 

Information pertaining to securities with gross unrealized losses at December 31, 2022 and 2021, aggregated by investment category and length of time that individual securities have been in a continuous loss position, is as follows:

There were no securities with other than temporary impairment losses at December 31, 2022 or 2021 respectively.  

Unrealized losses have not been recognized into income because, based on management’s evaluation, the decline in fair value is largely due to increased market rates, temporary market conditions and trading spreads, and, as such, are considered to be temporary by the Bank. In addition, management has the intent and ability to hold these securities until they mature or they recover their carrying values.

All U.S. Treasuries, U.S. government agency obligations, mortgage-backed residential obligations and collateralized mortgage obligations are agency-issued or government-sponsored enterprise issued. Agency-issued securities are generally guaranteed by a U.S. government agency, such as the Government National Mortgage Association. Government-sponsored enterprises, such as the Federal Home Loan Mortgage Corporation, the Federal National Mortgage Association, or the Small Business Administration, have either a direct or implied guarantee by the U.S. government.  

The Bank holds two classifications of municipal bonds, general obligation bonds and revenue bonds. General obligation bonds are backed by the general revenue of the issuing municipality, while revenue bonds are supported by a specific revenue source. All general obligation and revenue bonds have a bond rating of investment grade by Standard and Poor’s or Moody’s Investor Services or are not rated. The bonds that are not rated have been in a loss position less than 12 months. As of December 31, 2022, all municipal bond securities are paying as agreed. 

The following table represents the proceeds from the sale of securities available-for-sale and the related gross gains and losses during the periods presented.
