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.
