(1)These amounts consist of reverse repurchase transactions with overnight maturities. Reverse repurchase transactions are valued daily and are subject to collateral provisions based on which the counterparty must provide additional collateral if the underlying securities decrease in value, in an amount sufficient to maintain collateralization of at least 102%. Collateral received from the respective counterparties consists of sovereign bonds, consistent with Cboe Clear Europe's investment policy.

(2)These amounts are not reflected in the condensed consolidated balance sheets, as Cboe Clear Europe does not have the ability to sell or repledge the amounts absent a clearing member default.
