We evaluate securities with unrealized losses quarterly to determine if the decline in fair value has resulted from credit losses or other factors. We do not believe any individual unrealized loss as of December 31, 2022 represents a credit impairment. There were 147 debt securities in an unrealized loss position at December 31, 2022 and 31 debt securities in an unrealized loss position at December 31, 2021. The unrealized losses on debt securities were primarily attributable to changes in interest rates and not related to the credit quality of the issuers. All debt securities are determined to be investment grade and paying principal and interest according to the contractual terms of the security. We do not intend to sell and it is more likely than not that we will not be required to sell any of the securities in an unrealized loss position before recovery of their amortized cost.
