USAspending caveat. Figures are obligations reported by federal agencies to USAspending.gov, not payments. In USAspending's words: "An outlay occurs when federal money is actually paid out, not just promised to be paid ('obligated')." "Every agency has a Senior Accountable Official who must officially certify that the quarterly financial data submitted by their agency is accurate and complete." "If there are any discrepancies in procurement data, FPDS is the authoritative source."

The contracts column is listed only where contract obligations alone reached $1.0M; the assistance figure is the remainder and may therefore include up to $1.0M of contracts.
