The only ways I can think of.... 1. They were issued as restricted, then the investors maybe had a lawyrer's letter to allow the restrictive legend to be removed and then the shares may have been sold. 2. The 2 billion shares they got back from recision were used to give out at a steep discount for cash (dilution). Then see #1 above.
1 means a one 1 year wait still 2 I think they would be reset and still have a year on them. I am not by sure though.
