The above table includes 198 securities as of April 30, 2023, where the current fair value is less than the related amortized cost. Unrealized losses on the Company’s debt securities included in the above table are not considered to be credit-related based upon an analysis that considered the extent to which the fair value is less than the amortized basis of a security, adverse conditions specifically related to the security, changes to credit rating of the instrument subsequent to Company purchase, and the strength of the underlying collateral, if any.
