Terence & Jennifer Adderley Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation accepts requests by invitation only and does not take unsolicited applications, and its filing says its contributions are limited to preselected charitable organisations, so a small charity should not send a cold request and should first find a route to an invitation.
- Its filing states no geographic focus, although its grants have mainly gone to Michigan, so location is worth noting but is not a stated condition.
- About 8 in 10 of its 19 grants to organisations fall between $25,000 and $250,000, with a median of $50,000, so a request near that middle figure is in the typical range; its largest grant was $1,000,000, so that band is not a ceiling.
- In the latest filing, 94% of grant dollars to organisations went to groups it had also funded in one of its two previous filings, which suggests that existing relationships weigh heavily in who receives support.
