Operating model
- Revenue model
- Earned-program. 81% 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 - A large share of available resources goes toward mission work and the filed numbers largely add up. Total assets are small relative to annual expenses; liquid coverage is unknown and expenses are high relative to revenue.
