Seats are bought and sold via CBOE's membership department using an auction method in which bids and offers are submitted to the Exchange on an as-desired basis, and should a certain bid match a certain offer, a sale is made and the respective parties are notified.
CBOE, the world's largest options marketplace and the creator of listed options, is regulated by the SEC. For additional information about the CBOE and its products, access the CBOE website at: http://www.cboe.com/
