What The Tumori Foundation does
Mission
The Tumori Foundation is dedicated to improving our understanding and treatment of cancers of the eye and the surrounding area. It supports and performs eye tumor research. There is also a small fund set up to support the care of indigent patients who do not have resources to pay for care themselves.
As stated on its FY2019 Form 990.
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. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $3.3M to $2.6M (−21%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
74% of THE TUMORI FOUNDATION’s revenue is contributions — about as donation-reliant as the typical peer (82% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 3 reported years ran a deficit.

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.
