Release Items/Participants Requirements



Action Item  

Cash settlement of exercised/assigned OSTK contracts 

Corporate action processing of cash transactions resulting from exercise/assignment of stock option contracts (e.g. cash settled flexible contracts or settlement of fractions) will be brought in line with the migration to C7 SCS. Cash transaction types 294 CASH SETTLEMENT PAID and 296 CASH SETTLEMENT RCV will be generated and processed with a value date T+1. 

Clearing Members need to make the necessary adjustments on the reporting tools to support the new values. No new fields are being introduced. Reports impacted:  

  • “RPTCB702” Cash Settled Contracts Overview  

  • “RPTCE770” Exercise and Assign Overview 

  • “RPTCD710” Daily Cash Account CM 

Deliverable Bonds 

The text version of the “RPTCE038” Deliverable Bonds Report will be decommissioned. Only the xml version and csv format of the report will be generated and provided. 

Clearing Members are requested to make the necessary adjustments on the reporting tools. 

Collateral security enhancements 

Collateral reports will be affected by the removal of obsolete fields and smaller enhancements providing additional security information such as Country Code and additional parameters (pool/inflation factor) for a transparent representation of the collateral value calculation.  

Clearing Members need to make the necessary adjustments on the reporting tools. The following reports are affected:

This is an optional enhancement and no action required form Clearing Members. Configuration can be changed in “Modify Account” window in the “Account Overview” in C7 GUI. 

Existing close-out parameters are displayed on CA770 “Account Maintenance” report.

FIXML Broker migration 

Eurex Clearing FIXML broker will be migrated from qpid C++ to qpid Java. At the same time, TLS 1.0 and TLS 1.1 versions will be decommissioned and only security protocol TLS 1.2 and above will be supported.

In order to be compatible with qpid Java,customers need to ensure to be on AMQP version 1.0 or above.

Clearing Members are advised to note the differences in FIXML behavior with Java protocol compared to C++. 

Re-send test and failover test dedicated focus days are being offered to facilitate clearing participants to test system behavior.
