What this page does not know

  • Wrong if: a figure recovered from a subtotal is read as the sum of the recovered rows. A subtotal divides onto a whole penny whatever its parts did, so rows the per-row rule refuses are inside these figures.
  • What they say they exist to do
  • What each grant was for
  • What they fund, by theme
  • Balance sheet and financials
  • Who runs it
