Overview
Mission
The preservation of south mare island navy shipyard buildings dating from 1854-1996 and other artifacts.
Operating model
- 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.
The verdict
STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Revenue has declined or grown slowly and expenses are high relative to revenue.
