CharityIndex rating
One independent A+ to F grade from four published criteria, each scored separately from IRS filings and combined by weight.
C+
—Program efficiency40% of the ratingNo expense breakdown in filings
Measures how much of every dollar spent actually reaches programs, plus what it costs to raise $100 of donations. The worse of the two measures sets the letter (85%+ to programs is an A; under $15 to raise $100 is an A), averaged over the three most recent filings. Not scored for Whitney and Anne M Stone Foundation— this filing type doesn't report it, and the rating simply skips it (never counts it against the organization). See the exact thresholds →
B+Financial health25% of the rating87 mo reserves · -3% margin
Measures whether the organization is built to last: how many months its reserves would cover expenses (3+ months earns an A-range score, but hoarding 5+ years of budget is capped) and whether it runs a surplus or a deficit. For Whitney and Anne M Stone Foundation: 87 mo reserves · -3% margin earns a B+ on this criterion. See the exact thresholds →
—Governance25% of the ratingNot reported in this filing type
Checks how the organization is run, from its own Form 990: an independent board majority, a board of five or more, conflict-of-interest, whistleblower and document-retention policies, and independently audited financials. The share of disclosed checks that pass sets the letter. Not scored for Whitney and Anne M Stone Foundation— this filing type doesn't report it, and the rating simply skips it (never counts it against the organization). See the exact thresholds →
DTransparency10% of the rating1 of 5 disclosure signals
Counts five disclosure signals: a recent filing, a mission statement, program descriptions, a listed website, and the full expense breakdown. More disclosure, better letter. For Whitney and Anne M Stone Foundation: 1 of 5 disclosure signals earns a D on this criterion. See the exact thresholds →
