Just signed on to check my option settlement. It looks like I have some zombie COP options left unassigned. I had 300 shares of COP at the close of Friday so it looks like they took the shares (I was also short 1 other 55 strike call that is now gone), but I have some options that definitely should have been assigned that were left behind. I assume that this is just a glitch and that the positions will be gone on Monday. All other expired option positions have been removed.
