Operating model

Revenue model
Donor-supported. 67% 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

SUPPORTED - A large share of available resources goes toward mission work and the filed numbers largely add up. Some filing-based governance responses are negative or unanswered and total assets are small relative to annual expenses; liquid coverage is unknown.
