Information sharing on defaulter members: automatic cross-exchange defaulter recognition and action against associated parties required. When a member is declared a defaulter, the declaring Exchange/Clearing Corporation must immediately declare it a defaulter in all its segments and inform other Exchanges/Clearing Corporations of the member's identifying details; on receipt, those other Exchanges/Clearing Corporations must immediately declare the member a defaulter across their segments. Exchanges/Clearing Corporations must take appropriate action against associates of the defaulter, where associate covers control relationships, substantial shareholding, and overlapping directors or partners, with 'control' as defined under takeover regulations.
