Grants paid on this return

Grants paid, cash basis (Part I, line 25, column (d))
$235,359,065
As filed, and sometimes filed as 0.
Grants paid, Part XV total (line 3a)
$235,359,065
The foundation's own total of the grants it itemizes.

These are the grants the foundation paid during the year. The “Contributions, gifts and grants paid” total above is the figure on the foundation's books. This return marks the accrual method, under which a grant is recorded when the foundation commits to it rather than when it pays, so the books total need not agree with the cash figures in this section: a grant promised one year and paid in another is counted in different years.
