The following table presents the interest rate and foreign exchange assets and liabilities subject to an enforceable master netting arrangement as of September 30, 2023 and December 31, 2022. The interest rate and foreign exchange agreements the Corporation has with its commercial customers are not subject to an enforceable master netting arrangement and are therefore excluded from this table:
