Without knowing what the total reimbursement that Momenta had to pay Sandoz (nowhere close to the previously estimated $60 mil) we now don't now what the total net profit percentage is.
For example if Momenta's liability was in the $25 mil. range the COGS number plus expenses would be in the mid to upper 40% range instead of your 33% projection.
It'll take another quarter or so to really determine the final answers.
