Details of how to accept were in SGH's original bidder's statement of 10/5/21, you will find it now on the SGH investor website or through the ASX announcements but an excerpt is... It may be too late to do the acceptance form now given it was posted to you (I assume it is misplaced or you wouldn't be asking your Q) and the risk it won't make it by post by the cut off date. Best of luck.
