Operating model
- Revenue model
- Mixed. Its operating money came from several sources; no one source provided a clear majority.
- Distribution model
- Cannot be determined from the filing. The filing does not provide enough consistent spending detail to tell whether the nonprofit works directly or through others.
The verdict
STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Some filed totals do not add up and revenue has declined or grown slowly.
