Because of the history of just doing a R/S in the past. Looks like they've changed tactics now to just increasing the A/S; 350,000,000 in June and now another 750,000,000 5 months later.
I never thought they would stop printing shares, it's the only way they can generate money. As I posted last summer, since Cillo took over the company in 2008, they've increased shares something like 1.8+ billion, but it used to be done through R/S's and keeping the A/S capped.
