Unless I read the filings wrong, they listed out all of the notes that are/were convertible, and the ones that aren't(maturity dates, etc). I subtracted the differences and got about $332k as the amount that could have been converted after 7/31. Considering the approximate 1.86 billion shares traded since going current, even if a quarter of that was convertibles, that's 465 million(a fifth is 372 million). Figure out a median price, and you have how much debt may or may not have been erased.
I would think it should be somewhere near over, hence all the dooms-dayers, but that's just guesstimation...imo
Sooner or later, it will end. It always does, and this will move back up. It's just going to take time, and a solid multi-day bottom to do so.
