You clearly have no idea what you're talking about. The cash portion of the deal is $2.85. You aren't getting the CVR for "free" as you seem to think because the stock closed at $3.26. This will not be a CVR that trades like CELGZ or GCRVZ. You're locked in. So if you're certain the drug's sales will be good, great. Keep it. But if, several quarters from now, sales are stagnant, or if there's a health scare, or if a competing drug comes along, you're stuck. So, while a misinformed simpleton such as yourself can make an idiotic statement such as "you have to do nothing...", that's only true in the sense that you'll BE ABLE TO DO NOTHING as the CVR goes to zero, because you're stuck with the thing, unable to get out of the trap your arrogance and stupidity put you in.
So, once this deal closes, you'd better believe they hit their sales target with the drug, because $2.85 is all you get. If sales targets get made, great, but if ENDO can't make the drug sell, you will not be able to change your mind and dump the things.
