- Sum checks: major-funds expenses excluding transfers exact at $3,698,892,988 across all Table 1 lines; revenues and expenses both $4,387,962,174 including transfers; sales tax $1,514,673,289 + $129,611,658 = $1,644,284,947.
- What is not claimed: no separate General Fund total is headlined because the plan's headline is the major-funds total; the General Fund table inside the plan shows expenses and revenues of $2,850,101,265. NIFA's approval carried a condition requiring a modified financial plan addressing a potential sales-tax shortfall, health-insurance estimates, voluntary-separation savings, and unrecognized debt proceeds.
- Jurisdiction palette: no verified Nassau County palette was on file, so this page uses the neutral Hometown Numbers dark-glass theme rather than a county color.
