Failure To Deliver
  
Yep, doc. The baby's just gonna stay in there. Or not.
"Deliver" in this parlance also does not mean to surgically remove a liver. Instead, it refers to the delivery or documents supporting a given securities transaction.
Let's say the person buying the securities ended up being a Somalian warlord, and their cashola was frozen by the FBI. In that case, the salesperson could not deliver the securities fairly without violating all kinds of U.S. securities laws. It was a failure to deliver sitch.
