(14) Commitments and Contingencies
    
             The following table summarizes our expected contractual cash commitments as of June 30, 2011:
    
   
 
           Long-term debt obligations. Long-term debt obligations include principal payments on
   outstanding debt and capital lease obligations.
    
             Cash interest payments. Cash interest payments include interest due on outstanding debt
   through maturity.
    
             Satellite and transmission. We have entered into agreements with third parties to operate and
   maintain the off-site satellite telemetry, tracking and control facilities and certain components
   of our terrestrial repeater networks. We have also entered into various agreements to design and
   construct a satellite and related launch vehicle for use in our systems.
    
   
   
             We have an agreement with Space Systems/Loral to design and construct a fifth satellite, FM-6,
   for use in the SIRIUS system. In January 2008, we entered into an agreement with International
   Launch Services (ILS) to secure a satellite launch on a Proton rocket for this satellite.
    
             Programming and content. We have entered into various programming agreements. Under the terms
   of these agreements, we are obligated to provide payments to other entities that may include fixed
   payments, advertising commitments and revenue sharing arrangements.
    
             Marketing and distribution. We have entered into various marketing, sponsorship and
   distribution agreements to promote our brand and are obligated to make payments to sponsors,
   retailers, automakers and radio manufacturers under these agreements. Certain programming and
   content agreements also require us to purchase advertising on properties owned or controlled by the
   licensors. We also reimburse automakers for certain engineering and development costs associated
   with the incorporation of satellite radios into vehicles they manufacture. In addition, in the
   event certain new products are not shipped by a distributor to its customers within 90 days of the
   distributor’s receipt of goods, we have agreed to purchase and take title to the product.
    
             Satellite incentive payments. Boeing Satellite Systems International, Inc., the manufacturer
   of four of XM’s in-orbit satellites, may be entitled to future in-orbit performance payments with
   respect to two of our satellites. As of June 30, 2011, we have accrued $29,240 related to
   contingent in-orbit performance payments for XM-3 and XM-4 based on expected operating performance
   over their fifteen year design life. Boeing may also be entitled to an additional $10,000 if XM-4
   continues to operate above baseline specifications during the five years beyond the satellite’s
   fifteen-year design life.
    
             Space Systems/Loral may be entitled to future in-orbit performance payments. As of June 30,
   2011, we have accrued $11,659 and $21,450 related to contingent performance payments for FM-5 and
   XM-5, respectively, based on expected operating performance over their fifteen-year design life.
    
             Operating lease obligations. We have entered into cancelable and non-cancelable operating
   leases for office space, equipment and terrestrial repeaters. These leases provide for minimum
   lease payments, additional operating expense charges, leasehold improvements and rent escalations
   that have initial terms ranging from one to fifteen years, and certain leases that have options to
   renew. The effect of the rent holidays and rent concessions are recognized on a straight-line basis
   over the lease term, including reasonably assured renewal periods.
    
             Other. We have entered into various agreements with third parties for general operating
   purposes. In addition to the minimum contractual cash commitments described above, we have entered
   into agreements with other variable cost arrangements. These future costs are dependent upon many
   factors, including subscriber growth, and are difficult to anticipate; however, these costs may be
   substantial. We may enter into additional programming, distribution, marketing and other agreements
   that contain similar variable cost provisions.
    
             We do not have any other significant off-balance sheet arrangements that are reasonably likely
   to have a material effect on our financial condition, results of operations, liquidity, capital
   expenditures or capital resources.
    
        Legal Proceedings
    
             In the ordinary course of business, we are a defendant in various lawsuits and arbitration
   proceedings, including derivative actions; actions filed by subscribers, both on behalf of
   themselves and on a class action basis; former employees; parties to contracts or leases; and
   owners of patents, trademarks, copyrights or other intellectual property. Our significant legal
   proceedings are discussed under Item 1, Legal Proceedings in Part II, Other Information.
