Ann: Settlement of Class Action Proceedings, page-25

This is my understanding.

Every claimant should have already supplied the purchases that they made during the qualifying periods.
Shares bought outside the qualifying periods aren't part of the claim.
The claim was calculated as the difference between the purchase prices & a price at the time the claim was entered.
I believe that was $4.40 based on the Maurice Blackburn website,I could be wrong with that price.
If the claim was 100% successful you'd get the difference between the $4.40 & your purchase price less legal costs which appear to be around 25%.
As there was a settlement it's not 100% but likely (IMO) between 50% & 75%.

An example
(Purchase price $12.00 - Claim price $4.40) × 50% settlement -25% costs =$2.85 per share settlement

I don't believe the price you sold out at, if you have, is valid in calculating your settlement.
