This is the "Takeover Bid by TIO (NZ) Limited (ASX:FMS)" document dated 17/3/2016.
Please see the link above but I draw your attention to their previous takeover proposal on page 31-32 where TIO's intentions are stated. They acknowledge there would be a need for a special resolution requiring 75% of the votes to delist the company. There is also a condition stating there must be less than 150 minority shareholders with a minimum balance of $500 to allow for de-listing. (Safe to assume this is one of the main reasons for the 10% buyback announced on Thursday.)
Page 32 also mentions the "3% creep provision" rule under the Corporations Act and I do wonder how a 10% buy back gets around this legislation.
