If I were running this business the Incentive for getting Marketing Approval for Copaxone would have been structured like this
Marketing approval before March 2012 - 300K shares Marketing approval before March 2013 - 200K shares Marketing approval before March 2015 - 100K shares
Currently, the only incentive to get this approval done as quickly as possible before 2015 is the immediate vesting of half of the shares on approval date.
The only reason I can think of is maybe FDA is years away from really approving this very complex drug.
My guess is copaxone is nowhere near approval before 2013 ??
