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 total spending goes to programs.
