Operating model
- Revenue model
- Mixed. Its operating money came from several sources; no one source provided a clear majority.
- 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
MIXED - 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.
