Implications of Sale, page-7

You would need to do some calcs however, my quick calc shows that the franking credits is the way to go to get the best return if you are on a low tax of say no more than 10%.
My calcs assumed a 100% payout fully franked, though in reality they may only disburse 90% (my guess)

After that the sale at $0.45 and subject to CGT becomes attractive.
It must be pointed out that to get to $0.45 the share price would need to appreciate by some 15% from today's close of $0.39.

Furtherfor comparison purposes, assuming the share price moves in line with SYR, SYR would need to reach $6.80 and CSE would incur a tax liability of $20.7m reducing net amount available for distribution to $48.3m which works out to $0.45 for each of the 106.8m shares on issue by CSE.

I hope you get your sale price of $0.45
