It probably allocates a certain amount of funding per year to be used at HC’s discretion for what he feels is urgent.
It is vague of course. I know hockey coaches have something similar. Say there is something they feel is important for in the hockey lounge or something like that which is not covered by building fund, they can use some of these funds.
I was actually shocked once to hear that if Guy wanted to put up a hockey sweater of every HS team in the state, he would have to find funding for it, out of such funds, unless he could find a donor to specifically fund it. Pegula Bldg fund was not an option.
