Securities Collateral Deposit The Clearing Member opens a pledge account in one of ECCs securities collateral locations. All transfers to this account are automatically credited in ECCs clearing system near-time. If a collateral is not acceptable, the EUREX system instructs a deposit reversal.

ECC has concentration limits in place. The limits are published in the document "Accepted Securities". If a concentration limit is violated, ECC's Clearing & Settlement team will contact the member to initiate a replacement of securities.

The Collateral Transaction Overview window in the EUREX system provides an on-line view of the collateral posted.
 

Securities Collateral ReleaseWithdrawals are requested using the Security Collateral Transaction Entry window. Once the collateral is released, the securities are debited in near-time from the Clearing Member's collateral account

• If a withdrawal request leads to under-collateralisation in the member's account, the transfer of the requested securities is postponed.
• If a request is postponed, a cash call is initiated and the transfer is executed as soon as sufficient collateral is available.
