By fiscal year
Dollars committed from DOI to Solv LLC, per fiscal year (FY2018–FY2026).
* FY2026 is year-to-date — the fiscal year is still in progress, so its total is still filling in. The striped band and dashed line mark that provisional stretch.
How to read these numbers
- Just these two
Every figure is money committed between this agency (or bureau) and this recipient — nothing either did with anyone else.
- Totals by action year
The aggregates reflect the fiscal year picked at the top, counted in the year each action happened.
- “Active in FY X”
The award list shows every award between the two with an action that year, at its full lifetime value — so a single award's amount can top that year's committed total.
- Flags, not verdicts
Competition marks contracts competed on paper that drew a single offer; Where the money went next is the sub-awards the recipient itself reported — which can lag or under-report.
- From FY2018 on
Pairing pages start at fiscal year 2018, the first year of complete assistance reporting.
