From CDE7, each Friday as part of end of day processing, a trigger on behalf of ASX Operations will be received by the CSP and the CSP will process that trigger to establish if an eligible set of Corporate Action data exists. This will prompt the CSP to generate a Corporate Action Election Status Advice (evnt_743) for eligible requests according to the following rule:
When the CSP is ready to process Takeovers and Buybacks events that have an option offer close date in past 7 days (including current business date), a trigger on behalf of ASX Operations is automatically generated and sent to the CSP. The CSP will process that trigger and identify eligible Takeover and Buybacks according to rule mentioned earlier, if criteria is met then the CSP will generate and send a Corporate Action Election Status Advice (evnt_743) to the Controlling Participant of the Account (HIN) where a Locked Balance exists for the related Option Number of the Corporate Action Event Id.
For a detailed breakdown of available functionality, refer to the Takeovers and Buybacks (Bid Offers) Overview.
