Operating model
- Revenue model
- Earned-program. 89% of the money available for current operations came from fees and other program revenue.
- 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
STRONG - The filed numbers largely add up and a large share of available resources goes toward mission work. A relatively small share of total spending goes to programs and expenses are high relative to revenue.
