What Inter-American Tropical Tuna Commission does
Mission
The iattc is responsible for the conservation and management of fisheries for tunas and other species taken by tuna-fishing vessels in the eastern pacific ocean.
As stated on its FY2024 Form 990.
Programs
Aidcp on-board observer program to assess the status of dolphin populations by providing funding for observers on 100% of the fishing trips in large purse-seine size class 6 vessels. Its goal is to ensure the long-term sustainability of the tuna stocks in the agreement area, as well as that of the marine resources related to this fishery, taking into consideration the interrelationship among species in the ecosystem, with special emphasis on, inter alia, avoiding, reducing and minimizing bycatch and discards of juvenile tunas and non-target species.

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 2020 to 2021, from $6.8M to $11M (+57%).
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.
Government-grant reliance: 2017 65% · 2018 54% · 2019 59% · 2020 47% · 2021 67% · 2022 63% · 2023 64% · 2024 68%. Grants only. Government contracts and fees sit inside program revenue.
68% of INTER-AMERICAN TROPICAL TUNA COMMISSION’s revenue is contributions — more donation-reliant than the typical peer (67% for the typical peer).

Who funds it, year by year
2018 → 2020: the base held at 1 funder, grant income fell $16k → $14k.
1 of 2 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 54% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of INTER-AMERICAN TROPICAL TUNA COMMISSION’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
INTER-AMERICAN TROPICAL TUNA COMMISSION leans on a few funders — its largest provides 54% 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 INTER-AMERICAN TROPICAL TUNA COMMISSION.
Largest funder’s share by year: 2018 100% · 2020 100% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
54% of INTER-AMERICAN TROPICAL TUNA COMMISSION's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $14k that is directly attributable, 100% of it comes from funders outside California, across 1 state.
Funder states come from each funder’s own filing. $16k arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
