There were no holdings of securities of any one issuer, other than the U.S. Government and its sponsored entities, in an amount greater than 10% of shareholders’ equity. At September 30, 2020, the Company held 421 securities (122 available-for-sale and 299 held-to-maturity), of which one had fair value below amortized cost. At September 30, 2020, there were $245,000 of agency mortgage-backed securities held-to-maturity, at amortized cost, with an unrealized loss for less than 12 months. The total unrealized loss for securities less than 12 months was ($1,000) at September 30, 2020. The unrealized loss was due to higher interest rates in comparison to when the security was purchased. The issuer is of high credit quality and all principal amounts are expected to be paid when securities mature. The fair value is expected to recover as the securities approach their maturity date and/or market rates decline. The Company does not believe that it is more likely than not that the Company will be required to sell a security in an unrealized loss position prior to recovery in value. Therefore, the Company does not consider these debt securities to have credit related losses as of September 30, 2020.

The agency mortgage-backed securities and U.S. Treasury securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies, and have a long history of no credit losses.Therefore, for those securities, we do not record expected credit losses.

The proceeds from sales of securities and the resulting gains and losses were as follows for the periods indicated:

	Three Months Ended				Nine Months Ended

The amortized cost and estimated fair values of securities as of September 30, 2020 are shown by contractual maturity below. The expected maturities will differ from contractual maturities if borrowers have the right to call or pre-pay obligations with or without call or pre-payment penalties. Securities not due at a single maturity date are shown separately.

The table below presents a rollforward by major security type for the nine months ended September 30, 2020 of the allowance for credit losses on debt securities held-to-maturity held at period end:

For the nine months ended September 30, 2020, there was a reduction of $3,000 to the allowance for losses on the Company’s held-to-maturity municipal investment securities portfolio. This reduction was the result of a reduction in municipal securities amortized balances resulting from regular payments. The bond ratings for the Company’s municipal investment securities at September 30, 2020 were consistent with the ratings at January 1, 2020.
