Welcome to PP.
From your screenshot I assume that you use P6. Check the time for your "Must Finish By" - User Preferences --> show time.
It seems that it is earlier than the working time set by your standard calendar. So the assumed final activity is set to Oct 9, the Friday before. In my opinion it is easier to have a milestone "Contractual Finish" with a mandatory constrint, which is more visible than the Must Finish By.
Good luck!

Becuase that's how they work.Must finish by date on the project means the backward pass calc starts from the must finish by constraint date instead of the project early finish date, as normal. You wouldn't get negative float if the late date wasn't earlier than the early date -that's what negative float means.
