Two official figures, one label— reconciled below
Fiscal Receipts uses P-1/R-1 workbook total obligation authority (TOA) as the headline figure sitewide. The workbook TOA includes budget rows that the R-2/P-40 J-book program line excludes — advance procurement in an ordinary year, and in FY2026 the one-time reconciliation appropriation as well. Each row below names the one it is. How the two bases relate →
FY26 Request · $277.4M TOA − $135.9M J-book line = 141.6M (277.41 − 135.86 = 141.55) — $141.6M of one-time FY2026 reconciliation money accounts for this gap — not advance procurement
Figures in the sentence are rounded for reading; the parenthesised arithmetic is the same subtraction in USD millions, at the precision where it closes.
