(12) Stockholders’ Equity
    
        Common Stock, par value $0.001 per share
    
             We were authorized to issue up to 9,000,000,000 shares of common stock as of June 30, 2011 and
   December 31, 2010. There were 3,948,913,078 and 3,933,195,112 shares of common stock issued and
   outstanding as of June 30, 2011 and December 31, 2010, respectively.
    
             As of June 30, 2011, approximately 3,287,210,000 shares of common stock were reserved for
   issuance in connection with outstanding convertible debt, preferred stock, warrants, incentive
   stock awards and common stock to be granted to third parties upon satisfaction of performance
   targets.
    
             To facilitate the offering of the Exchangeable Notes, we entered into share lending agreements
   with Morgan Stanley Capital Services Inc. (“MS”) and UBS AG London Branch (“UBS”) in July 2008,
   under which we loaned MS and UBS an aggregate of 262,400,000 shares of our common stock in exchange
   for a fee of $0.001 per share. The obligations of MS to us under its share lending agreement are
   guaranteed by its parent company, Morgan Stanley. During the third quarter of 2009, MS returned to
   us 60,000,000 shares of our common stock borrowed in July 2008, which were retired upon receipt. As
   of June 30, 2011, there were 202,400,000 shares loaned under the facilities.
    
             Under each share lending agreement, the share loan will terminate in whole or in part, as the
   case may be, and the relevant borrowed shares must be returned to us upon the earliest of the
   following: (i) the share borrower terminates all or a portion of the loan between it and us,
   (ii) we notify the share borrower that some of the Exchangeable Notes as to which borrowed shares
   relate have been exchanged, repaid or repurchased or are otherwise no longer outstanding, (iii) the
   maturity date of the Exchangeable Notes, December 1, 2014, (iv) the date as of which the entire
   principal amount of the Exchangeable Notes ceases to be outstanding as a result of exchange,
   repayment, repurchase or otherwise or (v) the termination of the share lending agreement by the
   share borrower or by us upon default by the other party, including the bankruptcy of us or the
   share borrower or, in the case of the MS share lending agreement, the guarantor. A share borrower
   may delay the return of borrowed shares for up to 30 business days (or under certain circumstances,
   up to 60 business days) if such share borrower is legally prevented from returning the borrowed
   shares to us, in which case the share borrower may, under certain circumstances, choose to pay us
   the value of the borrowed shares in cash instead of returning the borrowed shares. Once borrowed
   shares are returned to us, they may not be re-borrowed under the share lending agreements. There
   were no requirements for the share borrowers to provide collateral.
    
             The shares we loaned to the share borrowers are issued and outstanding for corporate law
   purposes, and holders of borrowed shares (other than the share borrowers) have the same rights
   under those shares as holders of any of our other outstanding common shares. Under GAAP, the
   borrowed shares are not considered outstanding for the purpose of computing and reporting our net
   income (loss) per common share. The accounting method may change if, due to a default by either UBS
   or MS (or Morgan Stanley, as guarantor), the borrowed shares, or the equivalent value of those
   shares, will not be returned to us as required under the share lending agreements.
    
             We recorded interest expense related to the amortization of the costs associated with the
   share-lending arrangement and other issuance costs of $2,760 and $2,491, respectively, for the
   three months ended June 30, 2011 and 2010 and $5,450 and $4,918, respectively, for the six months
   ended June 30, 2011 and 2010. As of June 30, 2011, the unamortized balance of the debt issuance
   costs was $45,793, with $44,877 recorded in deferred financing fees, net, and $916 recorded in
   long-term related party assets. As of December 31, 2010, the unamortized balance of the debt
   issuance costs was $51,243, with $50,218 recorded in deferred financing fees, net, and $1,025
   recorded in long-term related party assets. As of June 30, 2011 and December 31, 2010, the
   estimated fair value of the remaining 202,400,000 loaned shares was approximately $443,256 and
   $329,912, respectively.
    
             In January 2004, SIRIUS signed a seven-year agreement with a sports programming provider which
   expired in February 2011. Upon execution of this agreement, SIRIUS delivered 15,173,070 shares of
   common stock valued at $40,967 to that programming provider. These shares of common stock were
   subject to transfer restrictions which lapsed over time. We recognized share-based payment expense
   associated with these shares of $0 and $219 in the three months ended June 30, 2011 and 2010,
   respectively, and $1,568 and $1,860 in the six months ended June 30, 2011 and 2010, respectively.
   As of June 30, 2011 and December 31, 2010, there was $0 and $1,568 remaining balance of common
   stock value included in other current assets, respectively.
    
        Preferred Stock, par value $0.001 per share
    
             We were authorized to issue up to 50,000,000 shares of undesignated preferred stock as of June
   30, 2011 and December 31, 2010.
    
   
   
             There were no shares of Series A Convertible Preferred Stock (“Series A Preferred Stock”)
   issued and outstanding as of June 30, 2011 and December 31, 2010.
    
             There were 12,500,000 shares of Series B Preferred Stock issued and outstanding as of June 30,
   2011 and December 31, 2010. The Series B Preferred Stock is convertible into shares of our common
   stock at the rate of 206.9581409 shares of common stock for each share of Series B Preferred Stock,
   representing approximately 40% of our outstanding shares of common stock (after giving effect to
   such conversion). As the holder of the Series B Preferred Stock, Liberty Radio LLC is entitled to a
   number of votes equal to the number of shares of our common stock into which such shares of Series
   B Preferred Stock are convertible. Liberty Radio LLC will also receive dividends and distributions
   ratably with our common stock, on an as-converted basis. With respect to dividend rights, the
   Series B Preferred Stock ranks evenly with our common stock and each other class or series of our
   equity securities not expressly provided as ranking senior to the Series B Preferred Stock. With
   respect to liquidation rights, the Series B Preferred Stock ranks evenly with each other class or
   series of our equity securities not expressly provided as ranking senior to the Series B Preferred
   Stock, and will rank senior to our common stock.
    
             There were no shares of Preferred Stock, Series C Junior (the “Series C Junior Preferred
   Stock”), issued and outstanding as of June 30, 2011 and December 31, 2010. In 2009, our board of
   directors created and reserved for issuance in accordance with the Rights Plan (as described below)
   9,000 shares of the Series C Junior Preferred Stock. The shares of Series C Junior Preferred Stock
   are not redeemable and rank, with respect to the payment of dividends and the distribution of
   assets, junior to all other series of our preferred stock, unless the terms of such series shall so
   provide. The Rights Plan expired on August 1, 2011.
    
        Warrants
    
             We have issued warrants to purchase shares of common stock in connection with distribution and
   programming agreements, satellite purchase agreements and certain debt issuances. As of June 30,
   2011, approximately 24,346,000 warrants to acquire an equal number of shares of common stock with
   an average exercise price of $2.96 per share were outstanding and fully vested as of December 31,
   2009 and expire at various times through 2015. For the three and six months ended June 30, 2011,
   525,000 and 1,575,000 of warrants expired, respectively.
    
             In February 2011, Daimler AG exercised 16,500,000 warrants to purchase shares of common stock
   on a net settlement basis, resulting in the issuance of 7,122,951 shares of our common stock.
    
        Rights Plan
    
             In April 2009, our board of directors adopted a rights plan. The terms of the rights and the
   rights plan are set forth in a Rights Agreement dated as of April 29, 2009 (the “Rights Plan”). The
   Rights Plan was intended to act as a deterrent to any person or group acquiring 4.9% or more of our
   outstanding common stock (assuming for purposes of this calculation that all of our outstanding
   convertible preferred stock is converted into common stock) without the approval of our board of
   directors. The Rights Plan expired on August 1, 2011.
