What Southern Arizona Tennis Association does
Mission
To promote the sport of tennis
As stated on its FY2019 Form 990-EZ.
Program
Promoting the growth of recreational tennis through tournaments leagues and tennis clinics. Estimated number of participants is 2,000.
The first program described on its most recent Form 990-EZ.
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 2018 to 2019, from $135k to $0 (−100%).
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.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 3 reported years ran a deficit.
Who funds it, year by year
2017 → 2019: the base broadened from 1 funder to 2 funders, grant income fell $56k → $19k.

How concentrated its funding is
SOUTHERN ARIZONA TENNIS ASSOCIATION leans on a few funders — its largest provides 87% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% 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 SOUTHERN ARIZONA TENNIS ASSOCIATION.
Largest funder’s share by year: 2017 100% · 2019 53% — diversifying over time.
