Payments for YouTube Rental Revenue
Videos that are monetized with Rentals will be paid through your linked Google Checkout business account. You will receive payments on a monthly schedule (subject to a minimum balance of $100) to the bank account you specified in Google Checkout.
You can track your Rentals earnings by logging into your Checkout account at http://checkout.google.com/sell and going to the Payouts tab.
