Operating model
- Revenue model
- Cannot be determined from the filing. The filing does not provide enough consistent revenue detail to tell how this nonprofit funds its work.
- 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
MIXED - The filed numbers largely add up and revenue comfortably covers expenses. A relatively small share of available resources goes toward mission work and program spending has declined or grown slowly.
