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
REVIEW - The filed numbers largely add up and revenue comfortably covers expenses. A relatively small share of available resources goes toward mission work and a relatively small share of total spending goes to programs.
