- Why can a contract amount be negative?
- The city records revisions and de-obligations as separate rows with negative award amounts. That means a vendor total is the net of original awards plus every later adjustment, not a running tally of payments. Awarded dollars are also not the same as dollars spent — a contract can be awarded and only partly drawn down.
