What Do You Think of the Larger Trend of Activism in Corporate America?

Ackman compared his amassing, his stake in Allergan and stealth to your purchase of Coca-Cola in the 1980s. What do you make of the covert tactic Ackman is using from a policy perspective for the markets? And just as important, what do you made of the larger trend of activism in corporate America? I'm really not sure how that would come about; we bought stock in the open market. We never used a derivative transaction or any sort in buying it or anything.
