Tombstone
  
It’s an announcement. And yes, it might seem strange for that to be on a tombstone, because usually you’d put something that...died. Or, at least, died the first time.
So tombstones used to be a common way of announcing a security’s offering in one form or another. That is, a company completed an IPO, a company placed a billion dollars of debt securities, a company was sold to a much bigger company, or a company was taken out of bankruptcy with the kindly, loving care of banks and, uh...other interested parties.
So then why the tombstone, when it feels like these companies have been given life all of a sudden? What was put to rest?
Answer: uncertainty. The tombstone was the death of confusion surrounding a particular security or offering or company.
