Method and limits
Download File A for FY2026 P11 at the TAS level, keep fixed-period accounts ending 2026 or 2027 with an unobligated balance above zero, and compute share unobligated.
Not a forecast of contract awards. Part of an unobligated balance may be reserved, apportioned for later, or legally unavailable. No-year accounts are excluded. Expired money can still pay for adjustments to existing obligations for five years.
