Operating model

Revenue model
Donor-supported. 75% of the money available for current operations came from contributions and gifts.
Distribution model
Transfer-based 990-EZ. The 990-EZ reports grants or member benefits, but it does not separate enough spending to show the nonprofit’s full delivery mix.

The verdict

REVIEW - The filed numbers largely add up and program spending has grown recently. A relatively small share of available resources goes toward mission work and revenue has declined or grown slowly.
