It's whatever they can afford that week. As I understand it, "asylum" has been audited several times for hollywood accounting.
For instance, by hollywood accounting, the Harry Potter series has yet to make one dollar of profit. But they have lawyers that could make satan back down, like the episode of Metalocalypse where he band tries to buy blues skills for merchandising rights and some sort of "store credit" with the band.
He says he needs to sleep on it, and bails as fast as he can.
Which actually benefits the band, as all the previous people to sign he contract went on murder sprees. I'm thinkin fine print.
