The total number of securities positions in the investment portfolio in an unrealized loss position at September 30, 2020 was 16 compared to 91 at December 31, 2019. At September 30, 2020, the Company had a position in one investment security with a fair value of $8 thousand and a total unrealized loss of less than $1 thousand that has been in a continuous unrealized loss position for more than 12 months. At September 30, 2020, there were a total of 15 securities positions in the Company’s investment portfolio with a fair value of $83.2 million and a total unrealized loss of $206 thousand that had been in a continuous unrealized loss position for less than 12 months. At December 31, 2019, the Company had positions in 34 investment securities with a fair value of $47.2 million and a total unrealized loss of $659 thousand that had been in a continuous unrealized loss position for more than 12 months. At December 31, 2019, there were a total of 57 securities positions in the Company’s investment portfolio with a fair value of $178.7 million and a total unrealized loss of $1.6 million that had been in a continuous unrealized loss position for less than 12 months. The unrealized loss on investment securities was predominantly caused by changes in market interest rates subsequent to purchase. The fair value of most of the investment securities in the Company’s portfolio fluctuates as market interest rates change.

Securities Available for Sale

As of September 30, 2020, no allowance for credit losses has been recognized on available for sale securities in an unrealized loss position as management does not believe any of the securities are impaired due to reasons of credit quality. This is based upon our analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors related to our available for sale securities and in consideration of our historical credit loss experience and internal forecasts. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. Furthermore, management does not have the intent to sell any of the securities classified as available for sale in the table above and believes that it is more likely than not that we will not have to sell any such securities before a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline.

Securities Held to Maturity

The Company’s HTM investment securities include debt securities that are issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. In addition, the Company’s HTM investment securities include debt securities that are issued by state and local government agencies, or municipal bonds.

The Company monitors the credit quality of our municipal bonds through the use of a credit rating agency or by ratings that are derived by an internal scoring model. The scoring methodology for the internally derived ratings is based on a series of financial ratios for the municipality being reviewed as compared to typical industry figures. This information is used to determine the financial strengths and weaknesses of the municipality, which is indicated with a numeric rating. This number is then converted into a letter rating to better match the system used by the credit rating agencies. As of September 30, 2020, $151.6 million of our municipal bonds were rated as an equivalent to Standard & Poor’s A/AA/AAA, with $8.5 million internally rated to be the equivalent of Standard & Poor’s A/AA/AAA rating. Additionally, one municipal bond is rated below investment grade, with a BB+ Standard & Poor’s equivalent rating. The below investment grade bond was recently upgraded from a Standard & Poor’s equivalent rating of BB-, represents exposure of $279 thousand, or 0.18% of the municipal bond portfolio and is closely monitored for repayment.

As of September 30, 2020, the Company had no past due or nonaccrual held to maturity investment securities.
