The Company did not hold any trading securities at September 30, 2020 and December 31, 2019. Securities available for sale are recorded at fair value. Securities held-to-maturity (“HTM”) are recorded at amortized cost.

The Company’s estimate of expected credit losses for held-to-maturity debt securities is based on historical information, current conditions and a reasonable and supportable forecast. The Company’s portfolio is made up of three securities, two of which are structured similar to a commercial owner occupied loan, which is modeled for credit losses similar to commercial business loans secured by real estate. The other security is issued and guaranteed by Fannie Mae, which is a government sponsored enterprise that has a credit rating and perceived credit risk comparable to the U.S. government and therefore the Company assumes a zero loss expectation. As of September 30, 2020, we have one active forbearance for held-to-maturity securities with an outstanding balance of $20.9 million. During the time this security is in forbearance, it is considered current and as such, continues to accrue interest at its original contractual terms. Accrued interest receivable on held-to-maturity securities totaled $0.1 million at September 30, 2020 and is excluded from estimates of credit losses.

The following table summarizes the Company’s portfolio of securities held-to-maturity at September 30, 2020:

The Company reviewed each available for sale debt security that had an unrealized loss at September 30, 2020 and December 31, 2019. At September 30, 2020, the Company evaluated whether the decline in fair value of a debt security resulted from credit losses or other factors under ASC 326. The Company does not have the intent to sell these securities and it is more likely than not the Company will not be required to sell the securities before recovery of the securities’ amortized cost basis. This conclusion is based upon considering the Company’s cash and working capital requirements and contractual and regulatory obligations, none of which the Company believes would cause the sale of the securities. All of these securities are rated investment grade or above and have a long history of no credit losses. It is not anticipated that these securities would be settled at a price that is less than the amortized cost of the Company’s investment.

In determining the risk of loss for available for sale securities, the Company considered that mortgage-backed securities are either fully guaranteed or issued by a government sponsored enterprise, which has a credit rating and perceived credit risk comparable to U.S. government, the issuer of Corporate securities are global systematically important banks, and the tranche of the purchased CLO’s. Each of these securities is performing according to its terms and, in the opinion of management, will continue to perform according to its terms. Based on this review, management believes that the unrealized losses have resulted from other factors not deemed credit-related and no allowance for credit loss was recorded.

Accrued interest receivable on available-for-sale debt securities totaled $1.4 million at September 30, 2020 and is excluded from the estimate of credit losses.

Upon adoption of ASC Topic 326, “Credit Losses” on January 1, 2020, see Note 17 related to the adoption of Topic 326, we recorded a transition adjustment of $0.3 million in the allowance for credit losses for held-to-maturity debt securities.
