Operating model

Revenue model
Cannot be determined from the filing. The filing does not provide enough consistent revenue detail to tell how this nonprofit funds its work.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

SUPPORTED - A large share of available resources goes toward mission work and the filed numbers largely add up. Program spending has declined or grown slowly and revenue has declined or grown slowly.
