A private foundation reports its assets twice. Book value is what it paid for them; fair market value is what they are worth now, and it is usually the larger of the two. Rankings on this site use book value, because that is the only measure a Form 990 and a Form 990-EZ also report, which keeps a foundation comparable with the charities beside it.

What this page cannot show
- Everything here is what the organization told the IRS about itself. The IRS publishes returns as filed and does not audit them first.
- The figures describe the most recent year on record, which is usually one to two years behind, and not the organization’s current position.
- Nothing here says whether the organization does its work well, or how it spends what it raises beyond the totals on the form.
