Allowance for Credit Losses The Company has adopted ASU 2016-13 that makes improvements to the accounting for credit losses on securities available for sale. The concept of other than-temporarily impaired securities has been replaced with the allowance for credit losses. Securities available for sale are evaluated on an individual level and pooling of securities is no longer an option. During this evaluation process, management considers the extent to which the fair value has been less than cost, the financial condition and near term prospects of the issuer, and the intent and ability of the Company to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. If the Company determines that a credit loss exists, the credit portion of the allowance will be measured using a discounted cash flow analysis using the effective interest rate as of the security’s purchase date. As of September 30, 2021, the Company’s security portfolio consisted of 718 securities, 146 of which were in an unrealized loss position. The majority of the unrealized losses on the Company’s securities are related to its holdings of U.S. Treasury and U.S. government sponsored entities and mortgage-backed securities. The Company does not consider its AFS securities with unrealized losses to be attributable to credit-related factors, as the unrealized losses have occurred as a result of changes in noncredit related factors such as changes in interest rates, market spreads and market conditions subsequent to purchase, not credit deterioration. As of September 30, 2021 the Company has no t recorded an allowance for credit losses on AFS securities.
