The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2017 to 2018, from $16M to $8.8M (−45%).
Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Left out of every figure on this page: $11M from one payer (the payer shares this organization's board, largest Grout Museum Inc). These are real filings, and they are not money HW GROUT TRUST raised.

the vertical line marks half of all grant income — 1 funder to its left
61% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund HW GROUT TRUST.
Largest funder’s share by year: 2017 85% · 2018 100% · 2019 68% · 2023 100% — growing more concentrated.
