National Academy of Sciences

One award, start to finish

Everything here is this single award's whole record — signed, amended, paid — not a fiscal-year slice. The by-year charts elsewhere split an award across the years it was committed; this page keeps it whole.

Committed vs. ceiling

Committed is what the government has legally promised on this award so far. Contracts can also carry a ceiling — the maximum if every option is exercised. Unspent ceiling is headroom, not money owed.

Paid out

The cash actually disbursed against this award. The gap from committed is the disbursement pipeline: promised, not yet cashed.

The ledger

Each transaction is a signing event — an action that created or changed the award, dated the day it was signed — not a payment. Negative amounts are real: money de-committed at closeout or renegotiation.

The money bar

One bar, the award’s whole arithmetic: paid out, then committed, not yet paid, then .
