Slight correction to what you said- Pierre has said that they would use 15% of revenue to buy back stock (not buy back 15% of the stock). I assume that is still the plan. As to how long such a buyback program would continue or how much of the stock SFMI will eventually buy back, that as far as I remember wasn't mentioned. A lot would depend on what SFMI's share price is at the time, and of course the buyback is intended to increase the share price, meaning the program will be able to buy less stock as things move along.
