Purse Distribution - New York

I noticed over the weekend (while watching the stakes action from Belmont) that all the horses in the stakes races in NY received a portion of the purse. Is this the case in all races in NY? And if so, what is the percent distribution? Also, I love this idea and I think that everyone should get some sort of purse allocation for at least running in the race. Certainly would help the little guys and really not make that much of a difference to the big guys.
