A note on the totals: the city files revisions and de-obligations as their own records with negative award amounts, so the total above is the net of awards and adjustments. An awarded amount is also not money paid — it is the ceiling the city agreed to, and actual spending can come in lower.

- 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.
