Our customers can always choose month-to-month services at the outset of their arrangement with us, or if they enter into a contract, they can exit at any time. In the case of our TV contracts, which we're talking about here today, they may refund to us a portion or all of the credit we gave them toward the cost of the professional install. If you enter into a contract, we waive the cost of the professional install, and then you can exit that contract any time and pay back, in the first year, the cost of that install, or, in the second year, half the cost of that install.
