Because they love to waste our tax dollars. I'm very ticked off that the SEC is dragging this out. IDLM is taking the punishment as a legitimate company for all the scams that are out there. This is what they should have done with 100 other companies that they let through.
Though possible, it's unlikely they found anything not already addressed with amendments. It is more likely just foot dragging so MMs with short positions won't complain that they didn't have enough time to cover.
