Description of Conditions Relating to Clearing of Interest rate Swaps | As a result of the Bank exceeding $10 billion in assets, federal regulations required the Bank, beginning in January 2019, to clear most interest rate swaps through a clearing house (“centrally cleared”). These instruments contain language outlining collateral pledging requirements for each counterparty, in which collateral must be posted if market value exceeds certain agreed upon threshold limits. Cash or securities are pledged as collateral. |
