The investment securities designated as having a continuous loss position for twelve months or more at March 31, 2023 consisted of fifty-four agency collateralized mortgage obligations, six capital trusts notes, seven asset-backed securities, eight corporate bonds, thirty-three US government agency bonds, 242 mortgage-backed securities, one mutual fund, and one municipal bond. The investment securities designated as having a continuous loss position for twelve months or more at December 31, 2022 consisted of twenty-three agency collateralized mortgage obligations, five capital trusts notes, seven asset-backed securities, two corporate bonds, thirty-three US government agency bonds, 133 mortgage-backed securities, one mutual fund, and one municipal bond.

The Company evaluates available-for-sale debt securities in unrealized loss positions at least quarterly to determine if an allowance for credit losses is required. We also assess whether (i) we intend to sell, or (ii) it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either of these criteria is met, any previously recognized allowances are charged off and the security’s amortized cost basis is written down to fair value through income. If neither of the aforementioned criteria are met, we evaluate whether the decline in fair value has resulted from credit losses or other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income.
In the first quarter of 2023, the company held a $20 million corporate bond in Signature Bank which was placed into receivership on March 12, 2023. We have taken a $20 million provision for credit loss and charged-off this security during the three months ended March 31, 2023.

None of the remaining unrealized losses identified as of March 31, 2023 or December 31, 2022 relates to the marketability of the securities or the issuers’ ability to honor redemption obligations. Rather, the unrealized losses relate to changes in interest rates relative to when the investment securities were purchased, and do not indicate credit-related impairment. Management based this conclusion on an analysis of each issuer including a detailed credit assessment of each issuer. The Company does not intend to sell, and it is not more likely than not that the Company will be required to sell the positions before the recovery of their amortized cost basis, which may be at maturity. As such, no allowance for credit losses remains with respect to debt securities as of March 31, 2023.
