Filing excerpt
The proceeds of the Existing 364-Day Credit Facility may be used to provide temporary liquidity in the unlikely event a clearing firm fails to promptly discharge an obligation to the clearing house operated by CME, in the event of a liquidity constraint or default by a depositary (custodian for our collateral), in the event of a temporary disruption with the domestic payments system that would delay payment of settlement variation between CME and its clearing firms, or in other cases as provided by the CME rulebook.
