At June 30, 2025, Park’s debt securities portfolio consisted of $954.5 million of securities, $795.3 million of which were in an unrealized loss position with aggregate unrealized losses of $62.0 million. Of the $795.3 million of securities in an unrealized loss position, $642.9 million were in an unrealized loss position for 12 months or longer. Of the $62.0 million in unrealized losses, $43.2 million were related to Park's "U.S. Government sponsored entities' asset-backed securities" portfolios. For non-agency debt securities, Park verified that the current credit ratings remain above investment grade. On a quarterly basis, management reviews the credit profile of each non-agency debt security and assesses whether any impairment to the contractually obligated cash flow is likely to occur. Based on these reviews, management has concluded that the underlying creditworthiness for each security remains sufficient to maintain required payment obligations and that changes in value are largely the result of changes in the yield curve, therefore, unrealized losses have not been recognized into net income. Management does not intend to sell, and it is not more likely than not that management would be required to sell, the securities prior to their anticipated recovery in respect of the unrealized losses. Management believes the value will recover as the securities approach maturity or market interest rates change.
