The answer is "All" of the proceeds go to his 501(c)(3) and then the money is distributed from there. I am a trustee and the co-chair on a 501(c)(3) foundation.

So is it standard to keep some of the money to cover operating costs and not count that as "Proceeds"? (Sorry, I'm very uneducated about this.)
