Found this today in the Admin Tab in YSM by the current account balance:
"If you link your Yahoo! account to a Microsoft Advertising adCenter account, only accounts with pre-paid balances of $25 or more will have such balances transferred to the adCenter accounts. Customers with accounts having pre-paid balances of less than $25 will receive refunds for such balances."
This of course doesn't say what will happen if you have more than $25 in an unlinked account. I'm guessing the Monkey will eat it and then fling it at the walls.
