Russ kinda touched on what I was going to say...
Do the fraternities & sororities themselves have a good amount of donations (of $$, materials and/or time) from their alums? If so, I'm guessing the school would like to divert some of that to their own coffers. It's one of those things where I guess it's hard to tell if alums will increase the amount of their donating and give to the college AND the GLO, or if they'll move their money.
Sorry if this makes no sense, I had a very festive night.
