I honestly have no idea as to how many have been bought back, but i agree with CYRXorbust that the company has bought back close to their goal of 150 million. XDrewX mentioned AYME has bought and kept around 150 million shares and he is a reliable member of this board. Keep in mind though that the company can only buy back 25% of the average daily volume so at most the company could theoretically buy back around 20-30 million shares a day, however they are also restricted to buying back shares at prices lower than the highest independent bid of any given session which doesn't mean much considering the u-shaped intraday pattern we have seen nearly every day the last month or so. All in all, buying back 150 million shares wouldn't take that long if the company has the cash, which i believe they do (thanks again to SM), so i would say they have bought back between 100-150 million shares, but until we get the K, your guess is as good as mine.
