Operating model
- Revenue model
- Donor-supported. 100% of the money available for current operations came from contributions and gifts.
- 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 voting board members are independent.
