Standard life flotation. windfalls? for all?

I hold a standard life mortgage and was contacted with the option of buying discounted shares but not to vote. am i eligible for the windfall payment? if so what is the average amount? should those qualifying expect payout this year?
Answer
You will only get a windafall if you hold a standard life policy - a mortgage is not enough. you have missed the date when you could have purchased discounted shares. shares were issued last week.
