Operating model

Revenue model
Membership-supported. 70% of the money available for current operations came from membership dues.
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. A relatively small share of available resources goes toward mission work and a relatively small share of total spending goes to programs.
