(1) The 2009 and 2008 financial information has been recast so that the basis of presentation is consistent with that of the 2010 and 2011 financial information. This recast reflects (i) the adoption of accounting guidance that amends the model for determining whether an entity should consolidate a variable interest entity, which resulted in the deconsolidation of the Oprah Winfrey Network and Animal Planet Japan and (ii) the results of operations of the Antenna Audio business as discontinued operations.

(2) The results for 2007 reflect only the results of Discovery Communications Inc.’s predecessor, Discovery Holding Company.
