How to buy right issue with CommSec?, page-6

Here’s another way to lower your average buy price by putting some money in your pocket from this deal if you are committed to holding. Work out your allocation by dividing your current holding by 2.51. After the last day for holding shares to qualify for the allocation, sell the equivalent number of shares on market that you currently hold equalling the number you will be allocated. Today’s price 37c. Take up your allocation when it is offered and you’ve lowered your original total cost by 17c/share x the allocated amount.
You’ve thus maintained your current holding and put some money back in your pocket. You’re also giving the company some much needed funds which they may or may not use wisely (hopefully wisely). You will however have a lower percentage of your company.
This is all just my opinion and you should definitely do your own research and this is not financial advice in any way.
