Operating model

Revenue model

Distribution model
Cannot be determined from the filing. The program-spending lines do not add up, so the filing cannot show reliably whether the nonprofit works directly or through others.

The verdict

SUPPORTED - A large share of available resources goes toward mission work and the filed numbers largely add up. Some filing-based governance responses are negative or unanswered and program spending has declined or grown slowly.
