"As of 14 July 2018, listed entities will be required to identify whether an announcement is "market sensitive" at the point of E-Lodgment on ASX online. Although ASX will still make the final determination before releasing the announcement, this new requirement reinforces the need for listed entities to be cognisant of what constitutes "market sensitive".
What are the changes?
An additional check-box will be included on the E-Lodgment form for ASX announcements made via ASX's online company announcement platform, which will require listed entities to identify whether or not the announcement is "market sensitive". Previously ASX was responsible for determining whether an announcement was "market sensitive" before releasing it. The changes are designed to improve the time taken to process and release announcements on ASX.
ASX is also introducing another change which will require listed entities to indicate whether or not the announcement materially references another listed entity."
