Operating model

Revenue model
Other-operating. 78% of the money available for current operations came from other operating revenue.
Distribution model
Direct operator. The filing allocates 93% 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.
  • Includes noncash contributions: Reported contributions include donated property or goods.

The verdict

STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. The filing reports few safeguards for money sent abroad and some filing-based governance responses are negative or unanswered.
