Operating model

Revenue model
Mixed. Its operating money came from several sources; no one source provided a clear majority.
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.
  • Includes noncash contributions: Reported contributions include donated property or goods.

The verdict

SUPPORTED - A large share of available resources goes toward mission work and the filed numbers largely add up. Fundraising costs are high for each dollar raised and expenses are high relative to revenue.
