Under the terms of a stockholders agreement, Liberty Media and Comcast are required to attempt to reach agreement on the fair market value of QVC within 30 days. Comcast will then have 30 days to elect to purchase Liberty’s stake in QVC. Should Comcast decline to purchase Liberty’s stake, Liberty has 30 days to purchase Comcast’s stake in the home shopping channel. If both companies decline their purchase options, QVC is required to be sold, and both parties are still eligible to bid.
