Sources and method
Figures on this page are computed from public federal award records. Numbers are never estimated or generated; where a figure is withheld, the reason is stated rather than filled in.
This page is a record of one federal award, assembled from the transactions the government published against it. Note 1 describes where the rollup came from. Values are award values, not unit prices.
- 1Rollup values derive from 80 transaction records parsed from USAspending.gov, retrieved Aug 17, 2026 by transform awards@2026.08.1.
- 2Obligations are the sum of signed federal action obligations across all transactions; deobligations are negative and remain negative.
- 3Current and potential award values are taken from the latest reported action, not summed across modifications.
