G'day T7 .... In addition to your answers - here might be some extra "illogical" ... but "possible" answers...
Q1 - A2: Because they may have preferential knowledge
Q2 - A2: Because the Board recommends it and suggests it is in their best interests to do so
A3: Because they have no option but to do so .... (Review Chapters 6 & 6A of the Corporations Act 2001)
Q3 - A2: Preferential knowledge
Q4 - A2: Although valuation based on historic numbers is not obvious - DCF and/or the balance sheet (intangibles) may be more obvious
Q5 - A2: Make sure they don't get manipulated and by joining together to oppose unfair takeovers
Q7 - A2: Because it provides opportunity for those who might wish to accumulate and/or receive bonus issues and/or takeover the company
Are these the answers of a conspiracist ... or a demented holder ... or a holder who has witnessed the events of an unfair takeover?
We'll see.
