Propublica has a nonprofit explorer (similar to Guidestar, but free) and tax filing viewer here: https://projects.propublica.org/nonprofits/organizations/460...

According to their FY2021 990 filing, they had $442k of "other" expenses.

It seems like they're required to disclose what those expenses are on the Schedule O form if they exceed 10% of all expenses, which they do, but I don't see the expenses enumerated there. (edit: oops, now I see)

I am, err, not a tax professional so I stopped here..
