SIRIUS XM RADIO INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
(Dollar amounts in thousands, unless otherwise stated)

(1) Business

          We broadcast our music, sports, news, talk, entertainment, traffic and weather channels in the United States on a subscription fee basis through our two proprietary satellite radio systems. Subscribers can also receive certain of our music and other channels over the Internet, including through applications for Apple, Blackberry and Android-powered mobile devices.

          Our primary source of revenue is subscription fees, with most of our customers subscribing on an annual, semi-annual, quarterly or monthly basis. We offer discounts for prepaid and long-term subscription plans as well as discounts for multiple subscriptions on each platform. We also derive revenue from activation and other fees, the sale of advertising on select non-music channels, the direct sale of satellite radios and accessories, and other ancillary services, such as our weather, traffic, data and Backseat TV services.

          Our satellite radios are primarily distributed through automakers (“OEMs”); nationwide through retail locations; and through our website. We have agreements with every major automaker to offer satellite radios as factory or dealer-installed equipment in their vehicles. Satellite radio services are also offered to customers of certain daily rental car companies.

          In July 2008, our wholly owned subsidiary, Vernon Merger Corporation, merged (the “Merger”) with and into XM Satellite Radio Holdings Inc. On August 5, 2008, we changed our name from Sirius Satellite Radio Inc. to Sirius XM Radio Inc. On January 12, 2011, XM Satellite Radio Inc., our wholly-owned subsidiary, merged with and into Sirius XM Radio Inc. All outstanding debt instruments held by XM Satellite Radio Inc. were assumed by Sirius XM Radio Inc. in the merger.

(2) Principles of Consolidation and Basis of Presentation

     Principles of Consolidation

          The accompanying unaudited consolidated financial statements of Sirius XM Radio Inc. and subsidiaries have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), the instructions to Form 10-Q and Article 10 of Regulation S-X of the United States Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, these interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. All significant intercompany transactions have been eliminated in consolidation.

     Basis of Presentation

          In the opinion of management, all normal recurring adjustments necessary for the fair presentation of our unaudited consolidated financial statements as of June 30, 2011 and for the three and six months ended June 30, 2011 and 2010 have been made.

          Interim results are not necessarily indicative of the results that may be expected for a full year. This Quarterly Report on Form 10-Q should be read together with our Annual Report on Form 10-K for the year ended December 31, 2010, which was filed with the SEC on February 16, 2011.

          We have evaluated events subsequent to the balance sheet date and prior to the filing of this Quarterly Report on Form 10-Q for the three and six months ended June 30, 2011 and have determined that no events have occurred that would require adjustment to our unaudited consolidated financial statements.

(3) Summary of Significant Accounting Policies

     Use of Estimates

          In presenting unaudited consolidated financial statements, management makes estimates and assumptions that affect the reported amounts and accompanying notes. Estimates, by their nature, are based on judgment and available information at this time. Actual results could differ materially from those estimates.

          Significant estimates inherent in the preparation of the accompanying unaudited consolidated financial statements include revenue recognition, asset impairment, useful lives of our satellites, share-based payment expense, and valuation allowances against deferred tax assets. Economic conditions in the United States could have a material impact on our accounting estimates.

     Recent Accounting Pronouncements

          In May 2011, the FASB issued Accounting Standards Update No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (Topic 820) — Fair Value Measurement (ASU 2011-04), to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for level 3 fair value measurements. The amendments are not expected to have a significant impact on companies that apply U.S. GAAP. This standard is effective for interim and annual periods beginning after December 15, 2011 and will be applied prospectively. We are currently evaluating the impact of our pending adoption of ASU 2011-04 on our consolidated financial statements.

          In June 2011, the FASB issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220) — Presentation of Comprehensive Income (ASU 2011-05), to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. The standard does not change the items which must be reported in other comprehensive income, how such items are measured or when they must be reclassified to net income. This standard is effective for interim and annual periods beginning after December 15, 2011 and will be applied retrospectively. ASU 2011-05 affects financial statement presentation only and will have no impact on our results of operations.

     Earnings per Share (“EPS”)

          Basic net income per common share is calculated using the weighted average common shares outstanding during each reporting period. Diluted net income per common share adjusts the weighted average common shares outstanding for the potential dilution that could occur if common stock equivalents (convertible debt and preferred stock, warrants, stock options, restricted stock and restricted stock units) were exercised or converted into common stock, calculated using the treasury stock method. Common stock equivalents of approximately 96,155,764 and 686,407,346 for the three months ended June 30, 2011 and 2010, respectively, and 109,334,669 and 692,011,065 for the six months ended June 30, 2011 and 2010, respectively, were excluded from the calculation of diluted net income per common share as the effect would have been anti-dilutive.

          Accounts receivable, net, consists of the following:

     Fair Value of Financial Instruments

          The fair value of a financial instrument is the amount at which the instrument could be exchanged in an orderly transaction between market participants to sell the asset or transfer the liability. As of June 30, 2011 and December 31, 2010, the carrying amounts of cash and cash equivalents, accounts and other receivables, and accounts payable approximated fair value due to the short-term nature of these instruments.

          The fair value for publicly traded instruments is determined using quoted market prices while the fair value for non-publicly traded instruments is based upon estimates from a market maker and brokerage firm. As of June 30, 2011 and December 31, 2010, the carrying value of our debt was $3,024,960 and $3,217,578, respectively; and the fair value approximated $3,488,874 and $3,722,905, respectively.

     Reclassifications

          Certain amounts in our prior period consolidated financial statements have been reclassified to conform to our current period presentation.

(4) Goodwill

          Goodwill represents the excess of the purchase price over the estimated fair value of net tangible and identifiable intangible assets acquired in business combinations. Our annual impairment assessment is performed as of October 1^st of each year, and an assessment is performed at other times if events or circumstances indicate it is more likely than not that the asset is impaired. During the three and six months ended June 30, 2011 and 2010, there were no indicators of impairment and no impairment loss was recorded to our goodwill.

     Indefinite Life Intangible Assets

          We have identified our FCC licenses and the XM trademark as indefinite life intangible assets after considering the expected use of the assets, the regulatory and economic environment within which they are used and the effects of obsolescence on their use.

          We hold FCC licenses to operate our satellite digital audio radio service and provide ancillary services. The following table outlines the years in which each of our licenses expires:

FCC license	Expiration year
SIRIUS FM-1 satellite		2017
SIRIUS FM-2 satellite		2017

(1)	In 2010, we retired the FM-4 ground spare satellite. We still maintain the FCC license for this satellite.
(2)	We hold an FCC license for the FM-6 satellite. The FCC license will expire eight years from launch of this satellite.

          Prior to expiration, we are required to apply for a renewal of our FCC licenses. The renewal and extension of our licenses is reasonably certain at minimal cost, which is expensed as incurred. Each of the FCC licenses authorizes us to use the broadcast spectrum, which is a renewable, reusable resource that does not deplete or exhaust over time.

          In connection with the Merger, $250,000 of the purchase price was allocated to the XM trademark. As of June 30, 2011, there were no legal, regulatory or contractual limitations associated with the XM trademark.

          Our annual impairment assessment of our indefinite intangible assets is performed as of October 1st of each year. An assessment is made at other times if events or changes in circumstances indicate that it is more likely than not that the assets have been impaired. As of June 30, 2011, there were no indicators of impairment and no impairment loss was recorded for intangible assets with indefinite lives during the three and six months ended June 30, 2011 and 2010.

     Liberty Media

          In February 2009, we entered into an Investment Agreement (the “Investment Agreement”) with an affiliate of Liberty Media Corporation, Liberty Radio, LLC (collectively, “Liberty Media”). Pursuant to the Investment Agreement, in March 2009 we issued to Liberty Radio, LLC 12,500,000 shares of our Convertible Perpetual Preferred Stock, Series B-1 (the “Series B Preferred Stock”), with a liquidation preference of $0.001 per share in partial consideration for certain loan investments. Liberty Media has representatives on our board of directors.

          The Series B Preferred Stock is convertible into 2,586,976,000 shares of common stock. Liberty Media has agreed not to acquire more than 49.9% of our outstanding common stock prior to March 2012, except that Liberty Media may acquire more than 49.9% of our outstanding common stock at any time pursuant to any cash tender offer for all of the outstanding shares of our common stock that are not beneficially owned by Liberty Media or its affiliates at a price per share greater than the closing price of the common stock on the trading day preceding the earlier of the public announcement or commencement of such tender offer. The Investment Agreement also provides for certain other standstill provisions ending in March 2012.

          Liberty Media has advised us that as of June 30, 2011 and December 31, 2010, respectively, it owned the following amounts of our debt securities:

          As of June 30, 2011 and December 31, 2010, we recorded $9,723 and $9,765, respectively, related to accrued interest with Liberty Media to Related party current liabilities. We recognized Interest expense associated with debt held by Liberty Media of $8,851 and $10,902 for the three months ended June 30, 2011 and 2010, respectively, and $17,784 and $19,964 for the six months ended June 30, 2011 and 2010, respectively.

     Sirius XM Canada

          In June 2011, Canadian Satellite Radio Holdings Inc. (“CSR”), the parent company of XM Canada, and SIRIUS Canada completed a transaction to combine their operations (“the Canada Merger”). As a result of the Canada merger, SIRIUS Canada is a wholly-owned subsidiary of CSR. The combined company will operate as Sirius XM Canada. In connection with the transaction, we received:

• approximately 46,700,000 Class A shares of CSR, representing a 38.0% equity interest and a 25.0% voting interest;

12

SIRIUS XM RADIO INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

• $53,781 in cash as repayment of the XM Canada credit facility ($38,815) and consideration for our preferred stock in SIRIUS Canada ($10,117 as a return of capital and $4,849 in dividends); and

• approximately $4,100 in non-interest bearing notes of CSR, which primarily have a two year term.

          Our interest in Sirius XM Canada will be accounted for under the equity method. The transaction was accounted for as a reverse acquisition whereby SIRIUS Canada was deemed to be the acquirer of CSR. As a result of the transaction, we recognized an $83,718 gain in Interest and investment income during the three months ended June 30, 2011.

          The excess of the cost of our ownership interest in the equity of Sirius XM Canada over our share of the net assets is recognized as goodwill and intangible assets and is included in the carrying amount of our investment. Equity method goodwill is not amortized. We will periodically evaluate this investment to determine if there has been an other than temporary decline below carrying value. Equity method intangible assets are amortized over their respective useful lives, which is recorded in Interest and investment income. As of June 30, 2011, our investment balance in Sirius XM Canada was approximately $54,800, $30,000 of which represents equity method goodwill and intangible assets, and was recorded in Related party long-term assets. Sirius XM Canada is still evaluating the fair value allocation between goodwill and intangible assets; the final purchase price allocation is not expected to have a material effect on our financial statements.

          We provide Sirius XM Canada with chipsets and other services and we are reimbursed for these costs. As of June 30, 2011, amounts due for these costs totaled $6,264 and is reported as Related party current assets.

          As of June 30, 2011, amounts due from Sirius XM Canada also included $7,576 attributable to deferred programming costs and accrued interest, all of which is reported as Related party long-term assets.

          We hold an investment in Cdn$4,000 face value of 8% convertible unsecured subordinated debentures issued by XM Canada and assumed by Sirius XM Canada, for which the embedded conversion feature is bifurcated from the host contract. The host contract is accounted for at fair value as an available-for-sale security with changes in fair value recorded to Accumulated other comprehensive loss, net of tax. The embedded conversion feature is accounted for at fair value as a derivative with changes in fair value recorded in earnings as Interest and investment income (loss). As of June 30, 2011, the carrying values of the host contract and embedded derivative related to our investment in the debentures was $3,537 and $4, respectively. As of December 31, 2010, the carrying values of the host contract and embedded derivative related to our investment in the debentures was $3,302 and $11, respectively. The carrying values of the host contract and embedded derivative are recorded in Related party long-term assets.

          Our share of net earnings or losses of Sirius XM Canada will be recorded to Interest and investment income (loss) in our unaudited consolidated statements of operations on a one month lag.

     SIRIUS Canada

          We had an equity interest of 49.9% in SIRIUS Canada until June 21, 2011 when the transaction between XM Canada and SIRIUS Canada closed. Our investment balance was zero as of December 31, 2010 as our investment balance was absorbed by our share of net losses generated by SIRIUS Canada.

          In 2005, we entered into a license and services agreement with SIRIUS Canada. Pursuant to such agreement, we are reimbursed for certain costs incurred to provide SIRIUS Canada service, including certain costs incurred for the production and distribution of radios, as well as information technology support costs. In consideration for the rights granted pursuant to this license and services agreement, we have the right to receive a royalty equal to a percentage of SIRIUS Canada’s gross revenues based on subscriber levels (ranging between 5% to 15%) and the number of Canadian-specific channels made available to SIRIUS Canada.

          We recorded the following revenue from SIRIUS Canada. Royalty income is included in other revenue and dividend income is included in Interest and investment income (loss) in our unaudited consolidated statements of operations:

          In 2005, XM entered into agreements to provide XM Canada with the right to offer XM satellite radio service in Canada. The agreements have an initial ten year term and XM Canada has the unilateral option to extend the agreements for an additional five year term. We receive a 15% royalty for all subscriber fees earned by XM Canada each month for its basic service and an activation fee for each gross activation of an XM Canada subscriber on XM’s system. Sirius XM Canada is obligated to pay us a total of $70,300 for the rights to broadcast and market National Hockey League (“NHL”) games for a ten year term. We recognize these payments on a gross basis as a principal obligor pursuant to the provisions of ASC 605, Revenue Recognition. The estimated fair value of deferred revenue from XM Canada as of the Merger date was approximately $34,000, which is amortized on a straight-line basis through 2020, the end of the expected term of the agreements. As of June 30, 2011 and December 31, 2010, the carrying value of deferred revenue related to this agreement was $27,405 and $28,792, respectively.

(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.

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.

          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.

(13) Benefits Plans

          We recognized share-based payment expense of $10,735 and $15,682 for the three months ended June 30, 2011 and 2010, respectively, and $22,023 and $31,223 for the six months ended June 30, 2011 and 2010, respectively. We did not realize any income tax benefits from share-based benefits plans during the three and six months ended June 30, 2011 and 2010 as a result of the full valuation allowance that is maintained for substantially all net deferred tax assets.

     2009 Long-Term Stock Incentive Plan

          In May 2009, our stockholders approved the Sirius XM Radio Inc. 2009 Long-Term Stock Incentive Plan (the “2009 Plan”). Employees, consultants and members of our board of directors are eligible to receive awards under the 2009 Plan. The 2009 Plan provides for the grant of stock options, restricted stock, restricted stock units and other stock-based awards that the compensation committee of our board of directors may deem appropriate. Vesting and other terms of stock-based awards are set forth in the agreements with the individuals receiving the awards. Stock-based awards granted under the 2009 Plan are generally subject to a vesting requirement. Stock-based awards generally expire ten years from the date of grant. Each restricted stock unit entitles the holder to receive one share of common stock upon vesting. As of June 30, 2011, approximately 271,986,000 shares of common stock were available for future grants under the 2009 Plan.

     Other Plans

          We maintain four other share-based benefit plans — the XM 2007 Stock Incentive Plan, the Amended and Restated Sirius Satellite Radio 2003 Long-Term Stock Incentive Plan, the XM 1998 Shares Award Plan and the XM Talent Option Plan. No further awards may be made under these plans. Outstanding awards under these plans are being continued.

          The following table summarizes the weighted-average assumptions used to compute the fair value of options granted to employees and members of our board of directors:

	For the Three Months						For the Six Months
	Ended June 30,						Ended June 30,
	2011			2010			2011			2010
Risk-free interest rate		1.8	%		2.2	%		1.8	%		2.5	%
Expected life of options — years		5.25			5.11			5.25			5.06
Expected stock price volatility		56	%		86	%		56	%		85	%
Expected dividend yield		0	%		0	%		0	%		0	%

          There were no options granted to third parties during the three and six months ended June 30, 2011 and 2010.

          We estimate fair value of awards granted using the hybrid approach for volatility, which weights observable historical volatility and implied volatility of qualifying actively traded options on our common stock. In 2010, due to the lack of qualifying actively traded options on our common stock, we utilized a 100% weighting to observable historical volatility.

          The following table summarizes stock option activity under our share-based payment plans for the six months ended June 30, 2011 (shares in thousands):

						Weighted-Average

          The weighted average grant date fair value of options granted during the six months ended June 30, 2011 and 2010 was $1.17 and $0.47, respectively. The total intrinsic value of stock options exercised during the six months ended June 30, 2011 and 2010 was $7,393 and $221, respectively.

          We recognized share-based payment expense associated with stock options of $9,920 and $10,254 for the three months ended June 30, 2011 and 2010, respectively, and $19,897 and $20,780 for the six months ended June 30, 2011 and 2010, respectively.

          The Sirius XM Plan allows eligible employees to voluntarily contribute from 1% to 50% of their pre-tax eligible earnings, subject to certain defined limits. We match 50% of an employee’s voluntary contributions, up to 6% of an employee’s pre-tax salary, in the form of shares of common stock. Employer matching contributions under the Sirius XM Plan vest at a rate of 33¹/₃% for each year of employment and are fully vested after three years of employment for all current and future contributions. Share-based payment expense resulting from the matching contribution to the plans was $814 and $718 for the three months ended June 30, 2011 and 2010, respectively, and $1,583 and $1,925 for the six months ended June 30, 2011 and 2010, respectively.

          We may also elect to contribute to the profit sharing portion of the Sirius XM Plan based upon the total eligible compensation of eligible participants. These additional contributions in the form of shares of common stock are determined by the compensation committee of our board of directors. Employees are only eligible to receive profit-sharing contributions during any year in which they are employed on the last day of the year. We currently do not anticipate contributing to the profit sharing portion of the Sirius XM Plan in 2011. Profit-sharing contribution expense was $0 and $2,594 for the three months ended June 30, 2011 and 2010, respectively, and $0 and $3,844 for the six months ended June 30, 2011 and 2010, respectively.

(1)	Includes captial lease obligations.
(2)	The table does not include our reserve for uncertain taxes, which at June 30, 2011 totaled $1,496, as the specific timing of any cash payments relating to this obligation cannot be projected with reasonable certainty.

          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.

21

SIRIUS XM RADIO INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

          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.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

               (All dollar amounts referenced in this Item 2 are in thousands, unless otherwise stated)

Special Note Regarding Forward-Looking Statements

          The following cautionary statements identify important factors that could cause our actual results to differ materially from those projected in forward-looking statements made in this Quarterly Report on Form 10-Q and in other reports and documents published by us from time to time. Any statements about our beliefs, plans, objectives, expectations, assumptions, future events or performance are not historical facts and may be forward-looking. These statements are often, but not always, made through the use of words or phrases such as “will likely result,” “are expected to,” “will continue,” “is anticipated,” “estimated,” “intend,” “plan,” “projection” and “outlook.” Any forward-looking statements are qualified in their entirety by reference to the factors discussed throughout this Quarterly Report on Form 10-Q and in other reports and documents published by us from time to time, particularly the risk factors described under “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2010 and “Management’s Discussion and Analysis of Financial Condition and Results or Operations” herein and in Part II, Item 7, of our Annual Report on Form 10-K for the year ended December 31, 2010.

          Among the significant factors that could cause our actual results to differ materially from those expressed in the forward-looking statements are:

• our competitive position versus other forms of audio and video entertainment including terrestrial radio, HD radio, Internet radio, mobile phones, iPods and other MP3 devices, and emerging next-generation networks and technologies;

• our ability to retain subscribers and maintain our average monthly revenue per subscriber;

• our dependence upon automakers and other third parties, such as manufacturers and distributors of satellite radios, retailers and programming providers;

• the first quarter tragedy in Japan, which may have certain adverse effects on automakers, radio manufacturers and other third parties that play a role in the supply of satellite radios;

• our substantial indebtedness; and

• the useful life of our satellites, which, in most cases, are not insured.

          Because the risk factors referred to above could cause actual results or outcomes to differ materially from those expressed in any forward-looking statements made by us or on our behalf, you should not place undue reliance on any of these forward-looking statements. In addition, any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which the statement is made, to reflect the occurrence of unanticipated events or otherwise. New factors emerge from time to time, and it is not possible for us to predict which will arise or to assess with any precision the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Executive Summary

          We broadcast our music, sports, news, talk, entertainment, traffic and weather channels in the United States on a subscription fee basis through two proprietary satellite radio systems. Subscribers can also receive certain of our music and other channels over the Internet, including through an application on Apple, Blackberry and Android-powered mobile devices.

          We have agreements with every major automaker (“OEMs”) to offer satellite radios as factory- or dealer-installed equipment in their vehicles. We also distribute our satellite radios through retail locations nationwide and through our website. Satellite radio services are also offered to customers of certain daily rental car companies.

          As of June 30, 2011, we had 21,016,175 subscribers. Our subscriber totals include subscribers under our regular pricing plans; discounted pricing plans; subscribers that have prepaid, including payments either made or due from automakers and dealers for subscriptions included in the sale or lease price of a vehicle; activated radios in daily rental fleet vehicles; certain subscribers to our Internet services; and certain subscribers to our weather, traffic, data and video services.

          Our primary source of revenue is subscription fees, with most of our customers subscribing on an annual, semi-annual, quarterly or monthly basis. We offer discounts for prepaid and long-term subscription plans, as well as discounts for multiple subscriptions on each platform. We also derive revenue from activation and other subscription-related fees, the sale of advertising on select non-music channels, the direct sale of satellite radios, components and accessories, and other ancillary services, such as our Backseat TV, data and weather services.

23

          In certain cases, automakers include a subscription to our radio services in the sale or lease price of new and certified pre-owned vehicles. The length of these prepaid subscriptions varies but is typically three to twelve months. In many cases, we receive subscription payments from automakers in advance of the activation of our service. We also reimburse various automakers for certain costs associated with satellite radios installed in their vehicles.

               We also have an interest in the satellite radio services offered in Canada. In June 2011, Canadian Satellite Radio Holdings Inc. (“CSR”), the parent company of XM Canada, and SIRIUS Canada completed a transaction to combine their operations (“the Canada Merger”). Following the Canada Merger, we own approximately 38.0% of the equity of CSR, which operates as Sirius XM Canada.

     Total Revenue

          Subscriber Revenue includes subscription fees, activation and other fees and the effects of rebates.

• Three Months: For the three months ended June 30, 2011 and 2010, subscriber revenue was $639,642 and $601,630, respectively, an increase of 6%, or $38,012. The increase was primarily attributable to an increase of 8% in daily weighted average subscribers and an increase in sales of premium services, including “Best of” programming, data services and streaming, partially offset by the impact of customer retention programs.

• Six Months: For the six months ended June 30, 2011 and 2010, subscriber revenue was $1,262,080 and $1,181,139, respectively, an increase of 7%, or $80,941. The increase was primarily attributable to an increase of 8% in daily weighted average subscribers and an increase in sales of premium services, including “Best of” programming, data services and streaming, partially offset by the impact of customer retention programs.

          The growth of future subscriber revenue will be dependent, among other things, upon the growth of our subscriber base, conversion and churn rates, promotions, rebates offered to subscribers and corresponding take-rates, plan mix, subscription prices and the identification of additional revenue streams from subscribers.

          Advertising Revenue includes the sale of advertising on our non-music channels, net of agency fees. Agency fees are based on a contractual percentage of the gross advertising billing revenue.

24

• Three Months: For the three months ended June 30, 2011 and 2010, advertising revenue was $18,227 and $15,797, respectively, an increase of 15%, or $2,430. The increase was primarily due to more effective sales efforts and improvements in the national market for advertising.

• Six Months: For the six months ended June 30, 2011 and 2010, advertising revenue was $34,785 and $30,323, respectively, an increase of 15%, or $4,462. The increase was primarily due to more effective sales efforts and improvements in the national market for advertising.

          Our advertising revenue is subject to fluctuation based on the effectiveness of our sales efforts and the national economic environment. We expect advertising revenue to grow as advertisers are attracted by the growth in our subscriber base and national advertising spend increases.

          Equipment Revenue includes revenue and royalties from the sale of satellite radios, components and accessories.

• Three Months: For the three months ended June 30, 2011 and 2010, equipment revenue was $17,022 and $18,520, respectively, a decrease of 8%, or $1,498. The decrease was driven by a decline in royalties from OEM installations due to the impact in the first quarter of the tragedy in Japan on automakers.

• Six Months: For the six months ended June 30, 2011 and 2010, equipment revenue was $32,889 and $32,802, respectively, an increase of $87. The increase was driven by royalties from increased OEM installations, partially offset by the impact in the first quarter of the tragedy in Japan on automakers.

          We expect equipment revenue to fluctuate based on OEM installations for which we receive royalty payments for our technology and, to a lesser extent, on the volume and mix of equipment sales in our direct to consumer business.

          Other Revenue primarily includes the U.S. Music Royalty Fee and revenue from affiliates.

• Three Months: For the three months ended June 30, 2011 and 2010, other revenue was $69,506 and $63,814, respectively, an increase of 9%, or $5,692. The increase was primarily due to an increase in subscribers subject to the U.S. Music Royalty Fee, which was partially offset by a reduction to that fee, and increased royalty revenue from Sirius Canada.

• Six Months: For the six months ended June 30, 2011 and 2010, other revenue was $138,482 and $119,280, respectively, an increase of 16%, or $19,202. The increase was primarily due to an increase in subscribers subject to the U.S. Music Royalty Fee, which was partially offset by a reduction to that fee, and increased royalty revenue from Sirius Canada.

               Future other revenues will be dependent upon revenues from our Canadian affiliate and the amount assessed for the U.S. Music Royalty Fee. We expect other revenue will grow as our subscribers subject to the U.S. Music Royalty Fee grow and as our Canadian affiliate grows.

     Operating Expenses

          Revenue Share and Royalties include distribution and content provider revenue share, advertising revenue share, residuals and broadcast and web streaming royalties. Residuals are monthly fees paid based upon the number of subscribers using satellite radios purchased from retailers. Advertising revenue share is recognized as a component of revenue share and royalties in the period in which the advertising is broadcast.

• Three Months: For the three months ended June 30, 2011 and 2010, revenue share and royalties were $116,741 and $107,901, respectively, an increase of 8%, or $8,840 and increased as a percentage of total revenue. The increase was primarily attributable to a 17% increase in our revenues subject to royalty and/or revenue sharing arrangements and a 7% increase in the statutory royalty rate for the performance of sound recordings, partially offset by a $4,717 increase in the benefit to earnings from the amortization of deferred credits on executory contracts initially recognized in purchase price accounting associated with the Merger.

• Six Months: For the six months ended June 30, 2011 and 2010, revenue share and royalties were $223,670 and $206,085, respectively, an increase of 9%, or $17,585 and remained flat as a percentage of total revenue. The increase was primarily attributable to a 16% increase in our revenues subject to royalty and/or revenue sharing arrangements and a 7% increase in the statutory royalty rate for the performance of sound recordings, partially offset by a $9,295 increase in the benefit to earnings from the amortization of deferred credits on executory contracts initially recognized in purchase price accounting associated with the Merger.

25

          We expect our revenue share and royalty costs to increase as our revenues grow, as we expand our distribution of satellite radios through automakers, and as a result of statutory increases in the royalty rate for the performance of sound recordings. Under the terms of the Copyright Royalty Board’s decision, we paid royalties of 7.5% and 7.0% of gross revenues, subject to certain exclusions, for the six months ended June 30, 2011 and 2010, respectively, and will pay royalties of 8.0% for 2012. The deferred credits on executory contracts initially recognized in purchase price accounting associated with the Merger are expected to provide increasing benefits to revenue share and royalties through the expiration of the acquired executory contracts, principally in 2012 and 2013.

          Programming and Content includes costs to acquire, create and produce content and on-air talent costs. We have entered into various agreements with third parties for music and non-music programming that require us to pay license fees, share advertising revenue, purchase advertising on media properties owned or controlled by the licensor and pay other guaranteed amounts.

• Three Months: For the three months ended June 30, 2011 and 2010, programming and content expenses were $67,399 and $72,019, respectively, a decrease of 6%, or $4,620, and decreased as a percentage of total revenue. The decrease was primarily due to savings in content agreements, production costs and general operating costs, partially offset by increases in personnel costs and a $1,915 reduction in the benefit to earnings from purchase price accounting adjustments associated with the Merger attributable to the amortization of the deferred credit on acquired programming executory contracts.

• Six Months: For the six months ended June 30, 2011 and 2010, programming and content expenses were $140,358 and $150,452, respectively, a decrease of 7%, or $10,094, and decreased as a percentage of total revenue. The decrease was primarily due to savings in content agreements, production costs and general operating costs, partially offset by increases in personnel costs and a $4,239 reduction in the benefit to earnings from purchase price accounting adjustments associated with the Merger attributable to the amortization of the deferred credit on acquired programming executory contracts.

               Based on our current programming offerings, we expect our programming and content expenses to decrease as agreements expire and are renewed or replaced on more cost effective terms. The impact of purchase price accounting adjustments associated with the Merger attributable to the amortization of the deferred credit on acquired programming executory contracts will continue to decline, in absolute amount and as a percentage of reported programming and content costs, through 2013.

          Customer Service and Billing includes costs associated with the operation of third party customer service centers and our subscriber management systems as well as bad debt expense.

• Three Months: For the three months ended June 30, 2011 and 2010, customer service and billing expenses were $62,592 and $58,414, respectively, an increase of 7%, or $4,178, and remained flat as a percentage of total revenue. The increase was primarily attributable to an increase of 8% in daily weighted average subscribers which drove higher call volume, billing and collection costs, transaction fees and personnel costs, partially offset by lower general operating costs.

• Six Months: For the six months ended June 30, 2011 and 2010, customer service and billing expenses were $128,429 and $114,625, respectively, an increase of 12%, or $13,804, and increased as a percentage of total revenue. The increase was primarily attributable to an increase of 8% in daily weighted average subscribers which drove higher call volume, billing and collection costs, transaction fees, bad debt expense and personnel costs, partially offset by lower general operating costs.

          We expect our customer service and billing expenses to increase as our subscriber base grows due to increased call center operating costs, transaction fees and bad debt expense.

          Satellite and Transmission consists of costs associated with the operation and maintenance of our satellites; satellite telemetry, tracking and control systems; terrestrial repeater networks; satellite uplink facilities; and broadcast studios.

• Three Months: For the three months ended June 30, 2011 and 2010, satellite and transmission expenses were $18,998 and $19,982, respectively, a decrease of 5%, or $984, and decreased as a percentage of total revenue. The decrease was primarily due to savings in repeater expenses and personnel costs.

• Six Months: For the six months ended June 30, 2011 and 2010, satellite and transmission expenses were $37,558 and $40,100, respectively, a decrease of 6%, or $2,542, and decreased as a percentage of total revenue. The decrease was primarily due to savings in repeater expenses and personnel costs.

          We expect satellite and transmission expenses to remain relatively flat as decreasing operating costs associated with our current in-orbit satellite fleet are offset by operating costs incurred on new satellites and increasing costs as we enhance our terrestrial repeater network.

26

          Cost of Equipment includes costs from the sale of satellite radios, components and accessories and provisions for inventory allowance attributable to products purchased for resale in our direct to consumer distribution channels.

• Three Months: For the three months ended June 30, 2011 and 2010, cost of equipment was $7,601 and $7,805, respectively, a decrease of 3%, or $204, and remained flat as a percentage of total revenue. The decrease was primarily due to lower inventory write-downs.

• Six Months: For the six months ended June 30, 2011 and 2010, cost of equipment was $14,006 and $15,724, respectively, a decrease of 11%, or $1,718, and remained flat as a percentage of total revenue. The decrease was primarily due to lower inventory write-downs and reduced costs to produce aftermarket radios.

          We expect cost of equipment to vary with changes in sales, supply chain management and inventory valuations.

          Subscriber Acquisition Costs include hardware subsidies paid to radio manufacturers, distributors and automakers, including subsidies paid to automakers who include a satellite radio and subscription to our service in the sale or lease price of a new vehicle; subsidies paid for chip sets and certain other components used in manufacturing radios; device royalties for certain radios; commissions paid to retailers and automakers as incentives to purchase, install and activate satellite radios; product warranty obligations; and provisions for inventory allowances attributable to inventory consumed in our OEM and retail distribution channels. The majority of subscriber acquisition costs are incurred and expensed in advance of, or concurrent with, acquiring a subscriber. Subscriber acquisition costs do not include advertising, loyalty payments to distributors and dealers of satellite radios and revenue share payments to automakers and retailers of satellite radios.

• Three Months: For the three months ended June 30, 2011 and 2010, subscriber acquisition costs were $105,162 and $110,383, respectively, a decrease of 5%, or $5,221, and decreased as a percentage of total revenue. The decrease was primarily a result of improved OEM subsidy rates per vehicle and a $1,510 increase in the benefit to earnings from the amortization of the deferred credit for acquired executory contracts recognized in purchase price accounting associated with the Merger, partially offset by the 8% increase in gross subscriber additions.

• Six Months: For the six months ended June 30, 2011 and 2010, subscriber acquisition costs were $210,432 and $199,762, respectively, an increase of 5%, or $10,670, but decreased as a percentage of total revenue. The increase was primarily a result of the 13% increase in gross subscriber additions and higher subsidies related to the 16% increase in OEM installations, partially offset by improved OEM subsidy rates per vehicle and a $5,500 increase in the benefit to earnings from the amortization of the deferred credit for acquired executory contracts recognized in purchase price accounting associated with the Merger.

          We expect total subscriber acquisition costs to fluctuate with increases or decreases in OEM installations and changes in our gross subscriber additions. Declines in the cost of subsidized radio components will also impact total subscriber acquisition costs. The impact of purchase price accounting adjustments associated with the Merger attributable to the amortization of the deferred credit for acquired executory contracts will vary, in absolute amount and as a percentage of reported subscriber acquisition costs, through the expiration of the acquired contracts, primarily in 2013. We intend to continue to offer subsidies, commissions and other incentives to acquire subscribers.

          Sales and Marketing includes costs for advertising, media and production, including promotional events and sponsorships; cooperative marketing; customer retention and personnel. Cooperative marketing costs include fixed and variable payments to reimburse retailers and automakers for the cost of advertising and other product awareness activities performed on our behalf.

• Three Months: For the three months ended June 30, 2011 and 2010, sales and marketing expenses were $51,442 and $56,177, respectively, a decrease of 8%, or $4,735, and decreased as a percentage of total revenue. The decrease was primarily due to reductions in consumer advertising and event marketing, partially offset by increased subscriber communications and retention programs.

• Six Months: For the six months ended June 30, 2011 and 2010, sales and marketing expenses were $99,261 and $105,294, respectively, a decrease of 6%, or $6,033, and decreased as a percentage of total revenue. The decrease was primarily due to reductions in consumer advertising and event marketing, partially offset by increased subscriber communications and retention programs.

          We expect sales and marketing expenses to increase as we increase advertising and promotional initiatives to attract new subscribers in existing and new distribution channels, and launch and expand programs to retain our existing subscribers and win-back former subscribers.

27

          Engineering, Design and Development includes costs to develop chip sets and new products, research and development for broadcast information systems and costs associated with the incorporation of our radios into vehicles manufactured by automakers.

• Three Months: For the three months ended June 30, 2011 and 2010, engineering, design and development expenses were $13,939 and $11,247, respectively, an increase of 24%, or $2,692, but remained flat as a percentage of total revenue. The increase was primarily due to higher aftermarket product development costs, partially offset by lower share-based payment expenses.

• Six Months: For the six months ended June 30, 2011 and 2010, engineering, design and development expenses were $25,074 and $22,684, respectively, an increase of 11%, or $2,390, but remained flat as a percentage of total revenue. The increase was primarily due to higher aftermarket product development costs, partially offset by lower share-based payment expenses.

          We expect engineering, design and development expenses to increase in future periods as we develop our next generation chip sets and products.

          General and Administrative includes rent and occupancy, finance, legal, human resources, information technology and investor relations costs.

• Three Months: For the three months ended June 30, 2011 and 2010, general and administrative expenses were $60,479 and $59,166, respectively, an increase of 2%, or $1,313, and remained flat as a percentage of total revenue. The increase was primarily due to an increase in legal settlement costs, partially offset by lower personnel costs and share-based payment expense.

• Six Months: For the six months ended June 30, 2011 and 2010, general and administrative expenses were $116,831 and $116,746, respectively, an increase of $85, but decreased as a percentage of total revenue. The increase was primarily due to higher legal costs, including settlement costs, partially offset by lower personnel costs and share-based payment expense.

          We expect our general and administrative expenses to increase in future periods primarily as a result of increased information technology and personnel costs to support the growth of our business, as well as rising legal costs.

          Depreciation and Amortization represents the systematic recognition in earnings of the acquisition cost of assets used in operations, including our satellite constellations, property, equipment and intangible assets, over their estimated service lives.

• Three Months: For the three months ended June 30, 2011 and 2010, depreciation and amortization expense was $67,062 and $69,230, respectively, a decrease of 3%, or $2,168, and decreased as a percentage of total revenue. The decrease was primarily due to a reduction in the amortization of subscriber relationships, partially offset by depreciation recognized on additional assets placed in service.

• Six Months: For the six months ended June 30, 2011 and 2010, depreciation and amortization expense was $135,462 and $139,495, respectively, a decrease of 3%, or $4,033, and decreased as a percentage of total revenue. The decrease was primarily due to a reduction in the amortization of subscriber relationships, partially offset by depreciation recognized on additional assets placed in service.

          We expect depreciation and amortization expenses to increase in future periods as we recognize depreciation expense on our recently launched satellite, XM-5, and complete the construction and launch of our FM-6 satellite, which will be partially offset by reduced depreciation and amortization associated with the stepped-up basis in assets acquired in the Merger (including intangible assets, satellites, property and equipment) through the end of their estimated service lives, principally through 2017.

          Restructuring, Impairments and Related Costs represents charges related to the re-organization of our staff and restructuring of contracts, as well as charges related to the impairment of assets when those costs are deemed to provide no future benefit.

• Three Months: For the three months ended June 30, 2010, restructuring, impairments and related costs were $1,803. The costs were related to the re-organization of our staff and contract termination costs in the three months ended June 30, 2010 with no such costs in 2011.

• Six Months: For the six months ended June 30, 2010, restructuring, impairments and related costs were $1,803. The costs were related to the re-organization of our staff and contract termination costs in the six months ended June 30, 2010 with no such costs in 2011.

28

     Other Income (Expense)

          Interest Expense, Net of Amounts Capitalized, includes interest on outstanding debt, reduced by interest capitalized in connection with the construction of our satellites and related launch vehicles.

• Three Months: For the three months ended June 30, 2011 and 2010, interest expense was $76,196 and $76,802, respectively, a decrease of $606. The decrease was primarily due to the mix of outstanding debt with lower interest rates, partially offset by lower capitalized interest related to the construction of our satellites and related launch vehicles.

• Six Months: For the six months ended June 30, 2011 and 2010, interest expense was $154,414 and $154,670, respectively, a decrease of $256. The decrease was primarily due to the mix of outstanding debt with lower interest rates, partially offset by lower capitalized interest related to the construction of our satellites and related launch vehicles.

          We expect interest expense to decline as debt outstanding declines due to retirements at maturity or call dates and through debt repurchases.

          Loss on Extinguishment of Debt and Credit Facilities, Net, includes losses incurred as a result of the conversion and retirement of certain debt.

• Three Months: For the three months ended June 30, 2011 and 2010, loss on extinguishment of debt and credit facilities, net, was $1,212 and $31,987, respectively, a decrease of 96%, or $30,775. During the three months ended June 30, 2011, the loss was incurred on the partial repayment of our 3.25% Convertible Notes due 2011. During the three months ended June 30, 2010, the loss was incurred on the repayment of SIRIUS’ 9.625% Senior Notes due 2013 and XM’s 10% Senior PIK Secured Notes due 2011.

• Six Months: For the six months ended June 30, 2011 and 2010, loss on extinguishment of debt and credit facilities, net, was $7,206 and $34,437, respectively, a decrease of 79%, or $27,231. During the six months ended June 30, 2011, the loss was incurred on the repayment of our 11.25% Senior Secured Notes due 2013 and the partial repayment of our 3.25% Convertible Notes due 2011. During the six months ended June 30, 2010, the loss was incurred on the repayment of SIRIUS’ Senior Secured Term Loan due 2012 and 9.625% Senior Notes due 2013 and XM’s 10% Senior PIK Secured Notes due 2011.

          Interest and Investment Income (Loss) includes realized gains and losses, dividends, interest income, our share of SIRIUS Canada’s and XM Canada’s net losses, the losses of our equity method affiliate, Sirius XM Canada net losses and losses recorded from investments in those entities, as well as debt instruments issued by XM Canada, when the fair value of those instruments falls below carrying value and the decline is determined to be other than temporary.

• Three Months: For the three months ended June 30, 2011 and 2010, interest and investment income was $80,182 and $378, respectively, an increase of $79,804. The increase was attributable to a gain realized as a result of the Canada Merger. This transaction resulted in the recognition of an $83,718 gain recorded in interest and investment income. The gain was partially offset by our share of higher net losses at XM Canada.

• Six Months: For the six months ended June 30, 2011 and 2010, interest and investment income (loss) was $78,298 and ($2,892), respectively, an increase of $81,190. The increase was attributable to a net gain realized as a result of the Canada Merger. This transaction resulted in the recognition of an $83,718 gain recorded in interest and investment income. The gain was partially offset by our share of higher net losses at XM Canada.

     Income Taxes

          Income Tax Expense primarily represents the deferred tax liability related to the difference in accounting for our FCC licenses, which are amortized over 15 years for tax purposes but not amortized for book purposes in accordance with GAAP and foreign withholding taxes on royalty income.

• Three Months: For the three months ended June 30, 2011 and 2010, income tax expense was $2,620 and $1,466, respectively, an increase of 79%, or $1,154. The increase was primarily due to an increase in foreign withholding taxes as a result of the Canada Merger and an increase in reserves for uncertain tax positions in various state jurisdictions.

• Six Months: For the six months ended June 30, 2011 and 2010, income tax expense was $4,192 and $2,633, respectively, an increase of 59%, or $1,559. The increase was primarily due to an increase in foreign withholding taxes as a result of the Canada Merger and an increase in reserves for uncertain tax positions in various state jurisdictions.

29

          We have previously disclosed the details of our deferred tax assets, including the amount of our net tax loss carryforwards, the expiration dates thereof and the valuation allowance related to our deferred tax assets. (See Note 14, Income Taxes, to the Consolidated Financial Statements in our Form 10-K for the year ended December 31, 2010 for further details regarding our deferred tax assets). In assessing the recoverability of our deferred tax assets, management regularly considers whether some portion or all of the deferred tax assets will not be realized based on the recognition threshold and measurement of a tax position in accordance with the Income Tax Topic of the FASB Accounting Standards Codification (the “Income Taxes Topic”). The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected taxable income and tax planning strategies in making this assessment. In accordance with the Income Taxes Topic, based upon the level of historical taxable losses, we have maintained a deferred tax valuation allowance against our deferred tax assets through June 30, 2011. In 2010, we had our first full year of pre-tax earnings yet continued to generate taxable losses. The first half of 2011 has continued with positive earnings and has generated taxable income. If such earnings trends continue, we may realize the benefits of all or a significant portion of our net deferred tax assets in 2012 through a reduction in our deferred tax valuation allowance. This would result in an income tax benefit that would be reflected in net income. As of December 31, 2010, we had $3.5 billion of valuation allowances established against the deferred tax assets.

          Subscribers. As of June 30, 2011 and 2010, subscribers were 21,016,175 and 19,527,448, an increase of 8%, or 1,488,727. Self-pay subscribers were 17,170,306 and 16,077,714, respectively, an increase of 7%, or 1,092,592. Paid promotional subscribers were 3,845,869 and 3,449,734, respectively, an increase of 11%, or 396,135. These improvements were primarily driven by an increase in U.S. light vehicle sales, new vehicle penetration and returning activations.

30

          Average Self-pay Monthly Churn is derived by dividing the monthly average of self-pay deactivations for the quarter by the average self-pay subscriber balance for the quarter. (See accompanying footnotes on pages 38 through 44 for more details.)

• Three Months: For the three months ended June 30, 2011 and 2010, our average self-pay monthly churn rate was 1.9% and 1.8%, respectively. Churn increased 6% primarily due to increases in deactivations due to changes in vehicle ownership, partially offset by reductions in non-pay cancellation rates.

• Six Months: For the six months ended June 30, 2011 and 2010, our average self-pay monthly churn rate was 1.9%.

          Conversion Rate is the percentage of owners and lessees of new vehicles that receive our service and convert to become self-paying subscribers after an initial promotional period. (See accompanying footnotes on pages 38 through 44 for more details.)

• Three Months: For the three months ended June 30, 2011 and 2010, our conversion rate was 45.2% and 46.7%, respectively. The decrease was primarily due to the changing mix of sales among auto manufacturers.

• Six Months: For the six months ended June 30, 2011 and 2010, our conversion rate was 44.9% and 45.9%, respectively. The decrease was primarily due to the changing mix of sales among auto manufacturers.

Adjusted Results of Operations

          In this section, we present certain financial performance measures that are not calculated and presented in accordance with generally accepted accounting principles in the United States of America (“Non-GAAP”). These Non-GAAP financial measures include: average monthly revenue per subscriber, or ARPU; subscriber acquisition cost, or SAC, per gross subscriber addition; customer service and billing expenses, per average subscriber; free cash flow; adjusted total revenue; and adjusted EBITDA. These measures exclude the impact of certain purchase price accounting adjustments. We use these Non-GAAP financial measures to manage our business, set operational goals and as a basis for determining performance-based compensation for our employees.

          The purchase price accounting adjustments include the elimination of the earnings benefit of deferred revenue associated with the investment in XM Canada, the recognition of subscriber revenues not recognized in purchase price accounting and the elimination of the earnings benefit of deferred credits on executory contracts, which are primarily attributable to third party arrangements with an OEM and programming providers.

          Our adjusted EBITDA also reallocates share-based payment expense from functional operating expense line items to a separate line within operating expenses. We believe the exclusion of share-based payment expense from functional operating expenses is useful given the significant variation in expense that can result from changes in the fair value as determined by the Black-Scholes-Merton model which varies based on assumptions used for the expected life, expected stock price volatility and risk-free interest rates; the effect of which is unrelated to the operational conditions that give rise to variations in the components of our operating costs.

          Free cash flow is a metric that our management and Board of Directors use to evaluate the cash generated by our operations, net of capital expenditures and other investment activity. In a capital intensive business, with significant historical and current investments in satellites, we look at our operating cash flow, net of these investing cash outflows, to determine cash available for future subscriber acquisition and capital expenditures, to repurchase or retire debt, to acquire other companies and to evaluate our ability to return capital to stockholders. We believe free cash flow is an indicator of the long-term financial stability of our business. Free cash flow, which is reconciled to “Net cash provided by (used in) operating activities”, is a financial measure that is not calculated and presented in accordance with generally accepted accounting principles in the United States of America. This measure can be calculated by deducting amounts under the captions “Additions to property and equipment” and deducting or adding “Restricted and other investment activity” from “Net cash provided by (used in) operating activities” from the consolidated statements of cash flows. Free cash flow should be used in conjunction with other GAAP financial performance measures and may not be comparable to free cash flow measures presented by other companies. Free cash flow should be viewed as a supplemental measure rather than an alternative measure of cash flows from operating activities, as determined in accordance with GAAP. Free cash flow is limited and does not represent remaining cash flows available for discretionary expenditures due to the fact that the measure does not deduct the payments required for debt maturities. We believe free cash flow provides useful supplemental information to investors regarding our current and projected cash flow, along with other GAAP measures (such as cash flows from operating and investing activities), to determine our financial condition and, to compare our operating performance to other communications, entertainment and media companies.

          We believe these Non-GAAP financial measures provide useful information to investors regarding our financial condition and results of operations. We believe investors find these Non-GAAP financial performance measures useful in evaluating our core trends because it provides a direct view of our underlying contractual costs. We believe investors use our current and projected adjusted EBITDA to estimate our current or prospective enterprise value and to make investment decisions. By providing these Non-GAAP financial measures, together with the reconciliations to the most directly comparable GAAP measure, we believe we are enhancing

31

investors’ understanding of our business and our results of operations. These Non-GAAP financial measures should be viewed in addition to, and not as an alternative for or superior to, our reported results prepared in accordance with GAAP. Please refer to the footnotes (pages 38 through 44) for a further discussion of such Non-GAAP financial measures and reconciliations to the most directly comparable GAAP measure.

          The following table contains our key operating metrics based on our unaudited adjusted results of operations for the three and six months ended June 30, 2011 and 2010, respectively:

	Unaudited
	For the Three Months Ended June 30,				For the Six Months Ended June 30,
(in thousands, except for per subscriber amounts)	2011		2010		2011		2010
ARPU (3)	$	11.53	$	11.81	$	11.53	$	11.65
SAC, per gross subscriber addition (4)	$	54	$	59	$	56	$	59
Customer service and billing expenses, per average subscriber (5)	$	1.00	$	1.01	$	1.04	$	1.00
Free cash flow (6)	$	165,433	$	108,331	$	148,559	$	(18,872	)
Adjusted total revenue (8)	$	747,335	$	705,560	$	1,474,896	$	1,376,122
Adjusted EBITDA (7)	$	185,094	$	154,313	$	366,454	$	312,070

Note: See pages 38 through 44 for footnotes.

          ARPU is derived from total earned subscriber revenue, net advertising revenue and other subscription-related revenue, net of purchase price accounting adjustments, divided by the number of months in the period, divided by the daily weighted average number of subscribers for the period. (See accompanying footnotes on pages 38 through 44 for more details.)

• Three Months: For the three months ended June 30, 2011 and 2010, ARPU was $11.53 and $11.81, respectively. The decrease was driven primarily by an increase in subscriber retention programs, the number of subscribers on OEM paid promotional plans and the decrease in the U.S. Music Royalty rate, partially offset by an increase in sales of premium services, including “Best of” programming, data services and streaming.

• Six Months: For the six months ended June 30, 2011 and 2010, ARPU was $11.53 and $11.65, respectively. The decrease was driven primarily by an increase in subscriber retention programs, the number of subscribers on promotional plans and the decrease in the U.S. Music Royalty rate, partially offset by an increase in sales of premium services, including “Best of” programming, data services and streaming.

          SAC, Per Gross Subscriber Addition is derived from subscriber acquisition costs and margins from the direct sale of radios and accessories, excluding share-based payment expense and purchase price accounting adjustments, divided by the number of gross subscriber additions for the period. (See accompanying footnotes on pages 38 through 44 for more details.)

• Three Months: For the three months ended June 30, 2011 and 2010, SAC, per gross subscriber addition was $54 and $59, respectively. The decrease was primarily due to an 8% increase in gross subscribers and lower per radio subsidy rates for certain OEMs.

• Six Months: For the six months ended June 30, 2011 and 2010, SAC, per gross subscriber addition was $56 and $59, respectively. The decrease was primarily due to a 13% increase in gross subscribers, lower per radio subsidy rates for certain OEMs and growth in subscriber reactivations and royalties from radio manufacturers, partially offset by an increase in OEM production with factory-installed satellite radios compared to the six months ended June 30, 2010.

          Customer Service and Billing Expenses, Per Average Subscriber is derived from total customer service and billing expenses, excluding share-based payment expense and purchase price accounting adjustments, divided by the number of months in the period, divided by the daily weighted average number of subscribers for the period. (See accompanying footnotes on pages 38 through 44 for more details.)

• Three Months: For the three months ended June 30, 2011 and 2010, customer service and billing expenses, per average subscriber was $1.00 and $1.01, respectively. The decrease was primarily due to the 8% growth in daily weighted average subscribers relative to an increase of 7% in customer service and billing expenses due to higher call volume and handle time per call and personnel costs.

• Six Months: For the six months ended June 30, 2011 and 2010, customer service and billing expenses, per average subscriber was $1.04 and $1.00, respectively. The increase was primarily due to higher call volume and handle time per

32

call, an increase to bad debt expense and personnel costs, partially offset by lower general operating costs and the 8% growth in daily weighted average subscribers.

          Free Cash Flow includes the net cash provided by operations, additions to property and equipment, merger related costs and restricted and other investment activity. (See accompanying footnotes on pages 38 through 44 for more details.)

• Three Months: For the three months ended June 30, 2011 and 2010, free cash flow was $165,433 and $108,331, respectively, an increase of $57,102. Net cash provided by operating activities increased $16,706 to $195,381 for the three months ended June 30, 2011 compared to the $178,675 provided by operations for the three months ended June 30, 2010. Capital expenditures for property and equipment for the three months ended June 30, 2011 decreased $30,033 to $40,315 compared to $70,348 for the three months ended June 30, 2010. Restricted and other investing activities increased $10,363 for the three months ended June 30, 2011. The increase in net cash provided by operating activities was primarily the result of improved operating performance driving higher adjusted EBITDA, cash received from the Canada Merger and higher collections from subscribers and distributors. The decrease in capital expenditures for the three months ended June 30, 2011 was primarily the result of decreased satellite construction and launch expenditures due to the launch in the fourth quarter of 2010 of our XM-5 satellite. The increase in restricted and other investment activities was driven by the return of capital resulting from the Canada Merger.

• Six Months: For the six months ended June 30, 2011 and 2010, free cash flow was $148,559 and ($18,872), respectively, an increase of $167,431. Net cash provided by operating activities increased $72,503 to $213,490 for the six months ended June 30, 2011 compared to the $140,987 provided by operations for the six months ended June 30, 2010. Capital expenditures for property and equipment for the six months ended June 30, 2011 decreased $94,015 to $75,298 compared to $169,313 for the six months ended June 30, 2010. Restricted and other investing activities increased $913 for the six months ended June 30, 2011. The increase in net cash provided by operating activities was primarily the result of improved operating performance driving higher adjusted EBITDA, cash received from the Canada Merger, higher collections from subscribers and distributors, and the repayment in the first quarter of 2010 of liabilities deferred in 2009. The decrease in capital expenditures for the six months ended June 30, 2011 was primarily the result of decreased satellite construction and launch expenditures due to the launch in the fourth quarter of 2010 of our XM-5 satellite. The increase in restricted and other investment activities was driven by the return of capital resulting from the Canada Merger, partially offset by proceeds from the sale of investment securities in the six months ended June 30, 2010.

          Adjusted Total Revenue. Our adjusted total revenue includes the recognition of deferred subscriber revenues acquired in the Merger that are not recognized in our results under purchase price accounting and the elimination of the benefit in earnings from deferred revenue associated with our investment in XM Canada acquired in the Merger. (See accompanying footnotes on pages 38 through 44 for more details.)

• Three Months: Our adjusted total revenue increased 6%, or $41,775, in the three months ended June 30, 2011 compared to the three months ended June 30, 2010. Subscriber revenue increased 6%, or $38,012, in the three months ended June 30, 2011 compared to the three months ended June 30, 2010. The increase in subscriber revenue was primarily attributable to an 8% increase in daily weighted average subscribers and an increase in sales of premium services, including “Best of” programming, data services and streaming. Other revenue increased 9%, or $5,692, in the three months ended June 30, 2011 compared to the three months ended June 30, 2010. The increase in other revenue was driven by an increase in subscribers subject to the U.S. Music Royalty Fee and increased royalty revenue from Sirius Canada. The purchase price accounting impact to subscriber revenue decreased $2,861 in the three months ended June 30, 2011 compared to the three months ended June 30, 2010.

• Six Months: Our adjusted total revenue increased 7%, or $98,774, in the six months ended June 30, 2011 compared to the six months ended June 30, 2010. Subscriber revenue increased 7%, or $80,941, in the six months ended June 30, 2011 compared to the six months ended June 30, 2010. The increase in subscriber revenue was primarily attributable to an 8% increase in daily weighted average subscribers and an increase in sales of premium services, including “Best of” programming, data services and streaming. Other revenue increased 16%, or $19,202, in the six months ended June 30, 2011 compared to the six months ended June 30, 2010. The increase in other revenue was driven by an increase in subscribers subject to the U.S. Music Royalty Fee and increased royalty revenue from Sirius Canada. The purchase price accounting impact to subscriber revenue decreased $5,918 in the six months ended June 30, 2011 compared to the six months ended June 30, 2010.

          Adjusted EBITDA. EBITDA is defined as net income (loss) before interest and investment income (loss); interest expense, net of amounts capitalized; income tax expense and depreciation and amortization. Adjusted EBITDA removes the impact of other income and expense, losses on extinguishment of debt as well as certain other charges, such as goodwill impairment; restructuring, impairments and related costs; certain purchase price accounting adjustments and share-based payment expense. (See accompanying footnotes on pages 38 through 44 for more details):

• Three Months: For the three months ended June 30, 2011 and 2010, adjusted EBITDA was $185,094 and $154,313, respectively, an increase of 20%, or $30,781. The increase was primarily due to an increase of 6%, or $41,775, in adjusted revenues, partially offset by an increase of 2%, or $10,994, in expenses included in adjusted EBITDA. The increase in adjusted revenues was primarily due to the increase in our subscriber base and the additional subscribers subject to the U.S. Music Royalty Fee. The increase in expenses was primarily driven by higher revenue share and royalties expenses associated with growth in revenues and increased customer service and billing expenses associated with subscriber growth, partially offset by lower subscriber acquisition costs, sales and marketing expenses, and programming and content costs.

• Six Months: For the six months ended June 30, 2011 and 2010, adjusted EBITDA was $366,454 and $312,070, respectively, an increase of 17%, or $54,384. The increase was primarily due to an increase of 7%, or $98,774 in adjusted revenues, partially offset by an increase of 4%, or $44,390, in expenses included in adjusted EBITDA. The increase in adjusted revenues was primarily due to the increase in our subscriber base and the additional subscribers subject to the U.S. Music Royalty Fee. The increase in expenses was primarily driven by higher revenue share and royalties expenses associated with growth in revenues, increased customer service and billing expenses associated with subscriber growth and higher subscriber acquisition costs related to the 13% increase in gross additions, partially offset by lower programming and content costs and sales and marketing expenses.

Liquidity and Capital Resources

Cash Flows for the Six Months Ended June 30, 2011 Compared with the Six Months Ended June 30, 2010

          As of June 30, 2011 and December 31, 2010, we had $528,327 and $586,691, respectively, of cash and cash equivalents. The following table presents a summary of our cash flow activity for the periods set forth below:

	For the Six Months Ended June 30,
	2011			2010			2011 vs. 2010
Net cash provided by operating activities	$	213,490		$	140,987		$	72,503
Net cash used in investing activities		(64,931	)		(159,859	)		94,928
Net cash used in financing activities		(206,923	)		(105,763	)		(101,160	)

Cash and cash equivalents at beginning of period		586,691			383,489			203,202
Cash and cash equivalents at end of period	$	528,327		$	258,854		$	269,473

Cash Flows Provided by Operating Activities

          Cash provided by operating activities increased by $72,503, or 51%, to $213,490 for the six months ended June 30, 2011 from cash provided by operating activities of $140,987 for the six months ended June 30, 2010. The primary drivers of our operating cash flow growth have been improvements in profitability and changes in operating assets and liabilities.

• Our net income was $251,440 and $56,870 for the six months ended June 30, 2011 and 2010, respectively. The increase in net income was primarily due to an increase in our subscriber revenues of $80,941, or 7%, for the six months ended June 30, 2011.

• Adjustments to net income were ($3,345) and $132,705 for the six months ended June 30, 2011 and 2010, respectively. Significant components of adjustments to net income, and their impact on cash flows from operating activities, include the following:

	For the Six Months Ended June 30,
	2011			2010
Depreciation and amortization	$	135,462		$	139,495
Loss on extinguishment of debt and credit facilities, net		7,206			34,437
Gain on merger of unconsolidated entities		(83,718	)		—
Share-based payment expense		23,591			33,083
Other non-cash purchase price adjustments		(134,862	)		(120,706	)

          Depreciation and amortization expense is expected to increase in future periods as we recognize depreciation expense on our recently launched satellite, XM-5, and complete the construction and launch of our FM-6 satellite.

          Loss on extinguishment of debt and credit facilities, net, includes losses incurred as a result of the conversion and retirement of certain debt instruments. Future charges related to the retirement or conversions of debt are dependent upon many factors, including the conversion price of debt or our ability to refinance or retire specific debt instruments.

          Gain on merger of unconsolidated entities represents the gain on the Canada Merger which closed in June 2011.

          Share-based payment expense is expected to increase in future periods as we grant equity awards to our employees and directors. Compensation expense for share-based awards is recorded in the financial statements based on the fair value of the underlying equity awards. The fair value of stock option awards is determined using the Black-Scholes-Merton option-pricing model which is subject to various assumptions including the market price of our stock, estimated forfeiture rates of awards and the volatility of our stock price. The fair value of restricted shares and restricted stock units is based on the market price of our stock at date of grant.

          Other non-cash purchase price adjustments include liabilities recorded as a result of the Merger related to executory contracts with an OEM and certain programming providers, as well as amortization resulting from changes in the value of deferred revenue as a result of the Merger.

35

• Changes in operating assets and liabilities reduced operating cash flows for the six months ended June 30, 2011 and 2010, $34,605 and $48,588, respectively. Significant changes in operating assets and liabilities include the timing of collections from our customers, the repayment of the XM Canada credit facility and the timing of payments to vendors and related parties. As we continue to grow our subscriber and revenue base, we expect that deferred revenue and amounts due from customers and distributors will continue to increase. Amounts payable to vendors are also expected to increase as our business grows. The timing of payments to vendors and related parties are based on both contractual commitments and the terms and conditions of each of our vendors.

Cash Flows Used in Investing Activities

               Cash used for investing activities consists primarily of capital expenditures for property and equipment. Capital expenditures have decreased following the successful launch of XM-5. We will continue to incur significant costs to construct and launch our new satellite and improve our terrestrial repeater network and broadcast and administrative infrastructure. We have entered into various agreements to design, construct and launch satellites in the normal course of business.

Cash Flows Used in Financing Activities

          Cash flows used in financing activities have generally been the result of the issuance and repayment of long-term debt and related party debt and cash proceeds from equity issuances. Proceeds from long-term debt, related party debt and equity issuances have been used to fund our operations, construct and launch new satellites and invest in other infrastructure improvements.

Financings and Capital Requirements

          We have historically financed our operations through the sale of debt and equity securities. The Certificate of Designations for our Series B-1 Preferred Stock provides that, so long as Liberty Media beneficially owns at least half of its initial equity investment, Liberty Media’s consent is required for certain actions, including the grant or issuance of our equity securities and the incurrence of debt (other than, in general, debt incurred to refinance existing debt) in amounts greater than $10,000 in any calendar year.

Future Liquidity and Capital Resource Requirements

          As disclosed in Note 14 to our unaudited consolidated financial statements, as of June 30, 2011, we are contractually obligated to incur capital expenditures of approximately $57,826 and $27,150 in 2011 and 2012, respectively, and an additional $53,272 over the next five years, the majority of which is attributable to the construction and launch of our FM-6 satellite and related launch vehicle.

          Based upon our current plans, we believe that we have sufficient cash, cash equivalents and marketable securities to cover our estimated funding needs. We expect to fund operating expenses, capital expenditures, working capital requirements, interest payments, taxes and scheduled maturities of our debt with existing cash and cash flow from operations, and we believe that we will be able to generate sufficient revenues to meet our cash requirements.

          Our ability to meet our debt and other obligations depends on our future operating performance and on economic, financial, competitive and other factors. We continually review our operations for opportunities to adjust the timing of expenditures to ensure that sufficient resources are maintained. Our financial projections are based on assumptions, which we believe are reasonable but contain significant uncertainties.

          We regularly evaluate our business plans and strategy. These evaluations often result in changes to our business plans and strategy, some of which may be material and significantly change our cash requirements. These changes in our business plans or strategy may include: the acquisition of unique or compelling programming; the introduction of new features or services; significant new or enhanced distribution arrangements; investments in infrastructure, such as satellites, equipment or radio spectrum; and acquisitions, including acquisitions that are not directly related to our satellite radio business.

Debt Covenants

          The indentures governing our debt include restrictive covenants. As of June 30, 2011, we were in compliance with our debt covenants.

          For a discussion of our “Debt Covenants”, refer to Note 11 to our unaudited consolidated financial statements in Item 1 of this Quarterly Report on Form 10-Q.

36

Off-Balance Sheet Arrangements

          We do not have any significant off-balance sheet arrangements other than those disclosed in Note 14 to our unaudited consolidated financial statements in Item 1 of this Quarterly Report on Form 10-Q that are reasonably likely to have a material effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources.

2009 Long-Term Stock Incentive Plan

          In May 2009, our stockholders approved the Sirius XM Radio Inc. 2009 Long-Term Stock Incentive Plan (the “2009 Plan”). Employees, consultants and members of our board of directors are eligible to receive awards under the 2009 Plan, which provides for the grant of stock options, restricted stock, restricted stock units and other stock-based awards that the compensation committee of our board of directors may deem appropriate. Vesting and other terms of stock-based awards are set forth in the agreements with the individuals receiving the awards. Stock-based awards granted under the 2009 Plan are generally subject to a vesting requirement. Stock-based awards generally expire ten years from the date of grant. Each restricted stock unit entitles the holder to receive one share of common stock upon vesting. As of June 30, 2011, approximately 271,986,000 shares of common stock were available for future grants under the 2009 Plan.

Other Plans

          We maintain four other share-based benefit plans — the XM 2007 Stock Incentive Plan, the Amended and Restated Sirius Satellite Radio 2003 Long-Term Stock Incentive Plan, the XM 1998 Shares Award Plan and the XM Talent Option Plan. No further awards may be made under these plans. Outstanding awards under these plans are being continued.

          For a discussion of our “Contractual Cash Commitments,” refer to Note 14 to our unaudited consolidated financial statements in Item 1 of this Quarterly Report on Form 10-Q.

Related Party Transactions

          For a discussion of “Related Party Transactions,” refer to Note 9 to our unaudited consolidated financial statements in Item 1 of this Quarterly Report on Form 10-Q.

Footnotes

(1)	Average self-pay monthly churn represents the monthly average of self-pay deactivations for the quarter divided by the average number of self-pay subscribers for the quarter.
(2)	We measure the percentage of owners and lessees of new vehicles that receive our service and convert to become self-paying subscribers after the initial promotion period. We refer to this as the “conversion rate.” At the time satellite radio enabled vehicles are sold or leased, the owners or lessees generally receive trial subscriptions ranging from three to twelve months. Promotional periods generally include the period of trial service plus 30 days to handle the receipt and processing of payments. We measure conversion rate three months after the period in which the trial service ends.
(3)	ARPU is derived from total earned subscriber revenue, net advertising revenue and other subscription-related revenue, net of purchase price accounting adjustments, divided by the number of months in the period, divided by the daily weighted average number of subscribers for the period. Other subscription-related revenue includes the U.S. Music Royalty Fee. Purchase price accounting adjustments include the recognition of deferred subscriber revenues not recognized in purchase price accounting associated with the Merger. ARPU is calculated as follows (in thousands, except for subscriber and per subscriber amounts):

(4) Subscriber acquisition cost, per gross subscriber addition (or SAC, per gross subscriber addition) is derived from subscriber acquisition costs and margins from the direct sale of radios and accessories, excluding purchase price accounting adjustments, divided by the number of gross subscriber additions for the period. Purchase price accounting adjustments associated with the Merger include the elimination of the benefit of amortization of deferred credits on executory contracts recognized at the Merger date attributable to an OEM. SAC, per gross subscriber addition, is calculated as follows (in thousands, except for subscriber and per subscriber amounts):

	Unaudited

(5) Customer service and billing expenses, per average subscriber, is derived from total customer service and billing expenses, excluding share-based payment expense and purchase price accounting adjustments associated with the Merger, divided by the number of months in the period, divided by the daily weighted average number of subscribers for the period. We believe the exclusion of share-based payment expense in our calculation of customer service and billing expenses, per average subscriber, is useful given the significant variation in expense that can result from changes in the fair market value of our common stock, the effect of which is unrelated to the operational conditions that give rise to variations in the components of our customer service and billing expenses. Purchase price accounting adjustments associated with the Merger include the elimination of the benefit associated with incremental share-based payment arrangements recognized at the Merger date. Customer service and billing expenses, per average subscriber, is calculated as follows (in thousands, except for subscriber and per subscriber amounts):

EBITDA is defined as net income before interest and investment income (loss); interest expense, net of amounts capitalized; taxes expense and depreciation and amortization. We adjust EBITDA to remove the impact of other income and expense, loss on extinguishment of debt as well as certain other charges discussed below. This measure is one of the primary Non-GAAP financial measures on which we (i) evaluate the performance of our businesses, (ii) base our internal budgets and (iii) compensate management. Adjusted EBITDA is a Non-GAAP financial performance measure that excludes (if applicable): (i) certain adjustments as a result of the purchase price accounting for the Merger, (ii) goodwill impairment, (iii) restructuring, impairments, and related costs, (iv) depreciation and amortization and (v) share-based payment expense. The purchase price accounting adjustments include: (i) the elimination of deferred revenue associated with the investment in XM Canada, (ii) recognition of deferred subscriber revenues not recognized in purchase price accounting, and (iii) elimination of the benefit of deferred credits on executory contracts, which are primarily attributable to third party arrangements with an OEM and programming providers. We believe adjusted EBITDA is a useful measure of the underlying trend of our operating performance, which provides useful information about our business apart from the costs associated with our physical plant, capital structure and purchase price accounting. We believe investors find this Non-GAAP financial measure useful when analyzing our results and comparing our operating performance to the performance of other communications, entertainment and media companies. We believe investors use current and projected adjusted EBITDA to estimate our current and prospective enterprise value and to make investment decisions. Because we fund and build-out our satellite radio system through the periodic raising and expenditure of large amounts of capital, our results of operations reflect significant charges for depreciation expense. The exclusion of depreciation and amortization expense is useful given significant variation in depreciation and amortization expense that can result from the potential variations in estimated useful lives, all of which can vary widely across different industries or among companies within the same industry. We believe the exclusion of restructuring, impairments and related costs is useful given the nature of these expenses. We also believe the exclusion of share-based payment expense is useful given the significant variation in expense that can result from changes in the fair value as determined using the Black-Scholes-Merton model which varies based on assumptions used for the expected life, expected stock price volatility and risk-free interest rates.

Adjusted EBITDA has certain limitations in that it does not take into account the impact to our statement of operations of certain expenses, including share-based payment expense and certain purchase price accounting for the Merger. We endeavor to compensate for the limitations of the Non-GAAP measure presented by also providing the comparable GAAP measure with equal or greater prominence and descriptions of the reconciling items, including quantifying such items, to derive the Non-GAAP measure. Investors that wish to compare and evaluate our operating results after giving effect for these costs, should refer to net income as disclosed in our consolidated statements of operations. Since adjusted EBITDA is a Non-GAAP financial performance measure, our calculation of adjusted EBITDA may be susceptible to varying calculations; may not be comparable to other similarly titled measures of other companies; and should not be considered in isolation, as a substitute for, or superior to measures of financial performance prepared in accordance with GAAP. The reconciliation of net income to the adjusted EBITDA is calculated as follows (in thousands):

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS

          As of June 30, 2011, we did not have any derivative financial instruments. We do not hold or issue any free-standing derivatives. We hold investments in marketable securities consisting of money market funds, and we also hold certificates of deposit and investments in debt and equity securities of other entities. We classify our investments in marketable securities as available-for-sale. These securities are consistent with the objectives in our investment policy. The basic objectives of our investment policy are the preservation of capital, maintaining sufficient liquidity to meet operating requirements and maximizing yield.

          Our debt includes fixed rate instruments and the fair market value of our debt is sensitive to changes in interest rates. Under our current policies, we do not use interest rate derivative instruments to manage our exposure to interest rate fluctuations.

ITEM 4. CONTROLS AND PROCEDURES

     Controls and Procedures

          As of June 30, 2011, an evaluation was performed under the supervision and with the participation of our management, including Mel Karmazin, our Chief Executive Officer, and David J. Frear, our Executive Vice President and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as that term is defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act). Based on that evaluation, our management, including our Chief Executive Officer and our Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of June 30, 2011. There has been no change in our internal control over financial reporting (as that term is defined in Rule 13a-15(f) and 15d-15(f) under the Securities Exchange Act) during the quarter ended June 30, 2011 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

          State Consumer Investigations. A Multistate Working Group of 28 State Attorneys General, led by the Attorney General of the State of Ohio, is investigating certain of our consumer practices. The investigation focuses on practices relating to the cancellation of subscriptions; automatic renewal of subscriptions; charging, billing, collecting, and refunding or crediting of payments from consumers; and soliciting customers.

          A separate investigation into our consumer practices is being conducted by the Attorney General of the State of Florida. In addition, in September 2010, the Attorney General of the State of Missouri commenced an action against us in Missouri Circuit Court, Twenty-Second Judicial Circuit, St. Louis, Missouri, alleging violations of various consumer protection statutes, including the Missouri Telemarketing No-Call List Act. The suit seeks, among other things, a permanent injunction prohibiting us from making, or causing to be made, telephone solicitations to our subscribers in the State of Missouri who are on Missouri’s no-call list, statutory penalties and reimbursement of costs.

          We are cooperating with these investigations and believe our consumer practices comply with all applicable federal and state laws and regulations.

          Carl Blessing et al. v. Sirius XM Radio Inc. In May 2011, we reached an agreement to settle the pending case entitled, Carl Blessing et al. v. Sirius XM Radio Inc. The settlement is contingent upon approval by the United States District Court for the Southern District of New York.

          Carl Blessing, a subscriber, filed a lawsuit against us in the United States District Court for the Southern District of New York. Mr. Blessing and several other plaintiffs purport to represent all subscribers who were subject to: an increase in the price for additional-radio subscriptions from $6.99 to $8.99; the imposition of the US Music Royalty Fee; and the elimination of our free streaming internet service. The suit claims that the pricing changes show that our merger with XM lessened competition or led to a monopoly in violation of the Clayton Act and that the merger led to monopolization in violation of the Sherman Act. Earlier the Court dismissed the plaintiffs’ claims for breach of contract and granted our motion for summary judgment as to various state law claims.

          As part of the settlement, we agreed that commencing on July 28, 2011, the date on which our voluntary commitment not to raise rates on our basic satellite programming package lapsed, through December 31, 2011, we will not: raise the price of our basic satellite radio service, our other programming packages or our internet streaming services; increase our US Music Royalty Fee; or decrease our multi-radio discount. Existing subscribers may renew their current subscription plans at our current rates prior to

45

December 31, 2011. Former subscribers who terminated their subscriptions after July 29, 2009 will be entitled to receive, at their election, either: one month of our basic satellite radio service or one month of our Internet streaming, at no charge. We have also agreed to pay the costs of providing notice to the plaintiff class and not to oppose an application by counsel for the plaintiffs for reimbursement of up to $13 million of their fees and expenses. The settlement does not require us to make any other cash payments to the plaintiff class or counsel to the plaintiffs.

          In connection with the settlement, we did not admit any wrongdoing, any violation of any statute or law, or the truth of any claims or allegations of the plaintiffs. Despite our belief that the claims asserted by the plaintiffs were untrue, we entered into this settlement because we believe it was in the best interest of our stockholders to avoid further legal expense and inconvenience and eliminate the distraction of this protracted litigation.

          One Twelve, Inc. and Don Buchwald v. Sirius XM Radio Inc. In March 2011, One Twelve, Inc., Howard Stern’s production company, and Don Buchwald, Stern’s agent, commenced an action against us in the Supreme Court of the State of New York, County of New York. The action alleges that, upon the Merger, we failed to honor our obligations under the performance-based compensation provisions of our prior agreement dated October 2004 with One Twelve and Buchwald, as agent; One Twelve and Buchwald each assert a claim of breach of contract. More specifically, the complaint alleges that subscribers to the XM Satellite Radio service should have been counted as “Sirius subscribers” following the Merger for purposes of provisions entitling One Twelve and Buchwald to compensation in the event that the number of “Sirius subscribers” exceeded the projected growth amounts of Sirius subscribers by certain magnitudes specified in the 2004 agreement for each year of that agreement. The suit seeks damages, plus interest and costs, in an amount to be determined. We believe that the claims are without merit and intend to vigorously defend this action.

          In July 2011, we filed a motion for summary judgment on the basis that the 2004 agreement is unambiguous; specifically, that the term “Sirius subscribers,” as used in the 2004 agreement, does not include subscribers to XM Satellite Radio following the merger and, as a result, One Twelve and Buchwald were not entitled to additional compensation for exceeding projected growth amounts of Sirius subscribers. The Court has scheduled oral argument on our motion for summary judgment for September 2011.

          Other Matters. 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. None of these actions are, in our opinion, likely to have a material adverse effect on our business, financial condition or results of operations.

     Indefinite Life Intangible Assets

          We have identified our FCC licenses and the XM trademark as indefinite life intangible assets after considering the expected use of the assets, the regulatory and economic environment within which they are used and the effects of obsolescence on their use.

          We hold FCC licenses to operate our satellite digital audio radio service and provide ancillary services. The following table outlines the years in which each of our licenses expires:

FCC license	Expiration year
SIRIUS FM-1 satellite		2017
SIRIUS FM-2 satellite		2017
SIRIUS FM-3 satellite		2017
SIRIUS FM-4 satellite(1)		2017
SIRIUS FM-5 satellite		2017
SIRIUS FM-6 satellite		(2)
XM-1 satellite		2014
XM-2 satellite		2014
XM-3 satellite		2013
XM-4 satellite		2014
XM-5 satellite		2018

(1)	In 2010, we retired the FM-4 ground spare satellite. We still maintain the FCC license for this satellite.
(2)	We hold an FCC license for the FM-6 satellite. The FCC license will expire eight years from launch of this satellite.

          Prior to expiration, we are required to apply for a renewal of our FCC licenses. The renewal and extension of our licenses is reasonably certain at minimal cost, which is expensed as incurred. Each of the FCC licenses authorizes us to use the broadcast spectrum, which is a renewable, reusable resource that does not deplete or exhaust over time.

          In connection with the Merger, $250,000 of the purchase price was allocated to the XM trademark. As of June 30, 2011, there were no legal, regulatory or contractual limitations associated with the XM trademark.

          Our annual impairment assessment of our indefinite intangible assets is performed as of October 1st of each year. An assessment is made at other times if events or changes in circumstances indicate that it is more likely than not that the assets have been impaired. As of June 30, 2011, there were no indicators of impairment and no impairment loss was recorded for intangible assets with indefinite lives during the three and six months ended June 30, 2011 and 2010.

     Definite Life Intangible Assets

          Subscriber relationships are amortized on an accelerated basis over 9 years, which reflects the estimated pattern in which the economic benefits will be consumed. Other definite life intangible assets include certain licensing agreements, which are amortized over a weighted average useful life of 9.1 years on a straight-line basis.

          Amortization expense for definite life intangible assets was $14,960 and $16,818 for the three months ended June 30, 2011 and 2010, respectively, and $30,263 and $34,114 for the six months ended June 30, 2011 and 2010, respectively. Expected amortization expense for the remaining period in 2011, each of the years 2012 through 2015 and for periods thereafter is as follows:

Year ending December 31,	Amount
Remaining 2011	$	28,817
2012		53,680

     Auction Rate Certificates

          Auction rate certificates are long-term securities structured to reset their coupon rates by means of an auction. We accounted for our investment in auction rate certificates as available-for-sale securities. In January 2010, our investment in the auction rate certificates was called by the issuer at par plus accrued interest, or $9,456, resulting in a gain of $425 in the six months ended June 30, 2010.

     Restricted Investments

          Restricted investments relate to reimbursement obligations under letters of credit issued for the benefit of lessors of office space. As of June 30, 2011 and December 31, 2010, our Long-term restricted investments were $3,146 and $3,396, respectively. During the three months ended June 30, 2011, $250 of obligations relating to these letters of credit were terminated.

Business

(1) Business

          We broadcast our music, sports, news, talk, entertainment, traffic and weather channels in the United States on a subscription fee basis through our two proprietary satellite radio systems. Subscribers can also receive certain of our music and other channels over the Internet, including through applications for Apple, Blackberry and Android-powered mobile devices.

          Our primary source of revenue is subscription fees, with most of our customers subscribing on an annual, semi-annual, quarterly or monthly basis. We offer discounts for prepaid and long-term subscription plans as well as discounts for multiple subscriptions on each platform. We also derive revenue from activation and other fees, the sale of advertising on select non-music channels, the direct sale of satellite radios and accessories, and other ancillary services, such as our weather, traffic, data and Backseat TV services.

          Our satellite radios are primarily distributed through automakers (“OEMs”); nationwide through retail locations; and through our website. We have agreements with every major automaker to offer satellite radios as factory or dealer-installed equipment in their vehicles. Satellite radio services are also offered to customers of certain daily rental car companies.

          In July 2008, our wholly owned subsidiary, Vernon Merger Corporation, merged (the “Merger”) with and into XM Satellite Radio Holdings Inc. On August 5, 2008, we changed our name from Sirius Satellite Radio Inc. to Sirius XM Radio Inc. On January 12, 2011, XM Satellite Radio Inc., our wholly-owned subsidiary, merged with and into Sirius XM Radio Inc. All outstanding debt instruments held by XM Satellite Radio Inc. were assumed by Sirius XM Radio Inc. in the merger.

Stockholders' Equity

Stockholders' Equity [Abstract]

Stockholders' Equity

(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.

(2) Principles of Consolidation and Basis of Presentation

     Principles of Consolidation

          The accompanying unaudited consolidated financial statements of Sirius XM Radio Inc. and subsidiaries have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), the instructions to Form 10-Q and Article 10 of Regulation S-X of the United States Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, these interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. All significant intercompany transactions have been eliminated in consolidation.

     Basis of Presentation

          In the opinion of management, all normal recurring adjustments necessary for the fair presentation of our unaudited consolidated financial statements as of June 30, 2011 and for the three and six months ended June 30, 2011 and 2010 have been made.

          Interim results are not necessarily indicative of the results that may be expected for a full year. This Quarterly Report on Form 10-Q should be read together with our Annual Report on Form 10-K for the year ended December 31, 2010, which was filed with the SEC on February 16, 2011.

          We have evaluated events subsequent to the balance sheet date and prior to the filing of this Quarterly Report on Form 10-Q for the three and six months ended June 30, 2011 and have determined that no events have occurred that would require adjustment to our unaudited consolidated financial statements.

Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

(3) Summary of Significant Accounting Policies

     Use of Estimates

          In presenting unaudited consolidated financial statements, management makes estimates and assumptions that affect the reported amounts and accompanying notes. Estimates, by their nature, are based on judgment and available information at this time. Actual results could differ materially from those estimates.

          Significant estimates inherent in the preparation of the accompanying unaudited consolidated financial statements include revenue recognition, asset impairment, useful lives of our satellites, share-based payment expense, and valuation allowances against deferred tax assets. Economic conditions in the United States could have a material impact on our accounting estimates.

     Recent Accounting Pronouncements

          In May 2011, the FASB issued Accounting Standards Update No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (Topic 820) — Fair Value Measurement (ASU 2011-04), to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for level 3 fair value measurements. The amendments are not expected to have a significant impact on companies that apply U.S. GAAP. This standard is effective for interim and annual periods beginning after December 15, 2011 and will be applied prospectively. We are currently evaluating the impact of our pending adoption of ASU 2011-04 on our consolidated financial statements.

          In June 2011, the FASB issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220) — Presentation of Comprehensive Income (ASU 2011-05), to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. The standard does not change the items which must be reported in other comprehensive income, how such items are measured or when they must be reclassified to net income. This standard is effective for interim and annual periods beginning after December 15, 2011 and will be applied retrospectively. ASU 2011-05 affects financial statement presentation only and will have no impact on our results of operations.

     Earnings per Share (“EPS”)

          Basic net income per common share is calculated using the weighted average common shares outstanding during each reporting period. Diluted net income per common share adjusts the weighted average common shares outstanding for the potential dilution that could occur if common stock equivalents (convertible debt and preferred stock, warrants, stock options, restricted stock and restricted stock units) were exercised or converted into common stock, calculated using the treasury stock method. Common stock equivalents of approximately 96,155,764 and 686,407,346 for the three months ended June 30, 2011 and 2010, respectively, and 109,334,669 and 692,011,065 for the six months ended June 30, 2011 and 2010, respectively, were excluded from the calculation of diluted net income per common share as the effect would have been anti-dilutive.

	For the Three Months				For the Six Months
	Ended June 30,				Ended June 30,
(in thousands, except per share data)	2011		2010		2011		2010

     Accounts Receivable

          Accounts receivable, net, is stated at amounts due from customers net of an allowance for doubtful accounts. Our allowance for doubtful accounts considers historical experience, the age of amounts due, current economic conditions and other factors that may affect the counterparty’s ability to pay.

          Accounts receivable, net, consists of the following:

	June 30,			December 31,
	2011			2010
Gross accounts receivable	$	112,661		$	131,880
Allowance for doubtful accounts		(11,827	)		(10,222	)
Total accounts receivable, net	$	100,834		$	121,658

          Receivables from distributors include billed and unbilled amounts due from OEMs for radio services included in the sale or lease price of vehicles, as well as billed amounts due from retailers. Receivables from distributors consist of the following:

	June 30,		December 31,
	2011		2010
Billed	$	43,997	$	30,456
Unbilled		37,017		37,120
Total	$	81,014	$	67,576

     Inventory

          Inventory consists of finished goods, refurbished goods, chip sets and other raw material components used in manufacturing radios. Inventory is stated at the lower of cost, determined on a first-in, first-out or market basis. We record an estimated allowance for inventory that is considered slow moving, obsolete or whose carrying value is in excess of net realizable value. The provision related to products purchased for resale in our direct to consumer distribution channel and components held for resale by us is reported as a component of Cost of equipment in our unaudited consolidated statements of operations. The provision related to inventory consumed in our OEM and retail distribution channel is reported as a component of Subscriber acquisition costs in our unaudited consolidated statements of operations.

          Inventory, net, consists of the following:

	June 30,			December 31,
	2011			2010
Raw materials	$	25,870		$	18,181
Finished goods		27,430			24,492
Allowance for obsolescence		(20,983	)		(20,755	)
Total inventory, net	$	32,317		$	21,918

     Fair Value of Financial Instruments

          The fair value of a financial instrument is the amount at which the instrument could be exchanged in an orderly transaction between market participants to sell the asset or transfer the liability. As of June 30, 2011 and December 31, 2010, the carrying amounts of cash and cash equivalents, accounts and other receivables, and accounts payable approximated fair value due to the short-term nature of these instruments.

          The fair value for publicly traded instruments is determined using quoted market prices while the fair value for non-publicly traded instruments is based upon estimates from a market maker and brokerage firm. As of June 30, 2011 and December 31, 2010, the carrying value of our debt was $3,024,960 and $3,217,578, respectively; and the fair value approximated $3,488,874 and $3,722,905, respectively.

     Reclassifications

          Certain amounts in our prior period consolidated financial statements have been reclassified to conform to our current period presentation.

     (a) 3.25% Convertible Notes due 2011

          In October 2004, we issued $230,000 in aggregate principal amount of 3.25% Convertible Notes due October 15, 2011 (the “3.25% Notes”), which are convertible, at the option of the holder, into shares of our common stock at any time at a conversion rate of 188.6792 shares of common stock for each $1,000 principal amount, or $5.30 per share of common stock, subject to certain adjustments. Interest is payable semi-annually on April 15 and October 15 of each year. The obligations under the 3.25% Notes are not secured by any of our assets.

          In 2011, we purchased $168,113 of the outstanding 3.25% Notes at prices between 100.75% and 101% of the principal amount plus accrued interest. We recognized a loss on extinguishment of debt for the 3.25% Notes of $1,212 for the three months ended June 30, 2011 and $2,291 for the six months ended June 30, 2011, which consists primarily of cash premiums paid, unamortized discount and deferred financing fees.

Substantially all of our domestic wholly-owned subsidiaries guarantee our obligations under the 7.625% Senior Notes.

     Covenants and Restrictions

          Our debt generally requires compliance with certain covenants that restrict our ability to, among other things, (i) incur additional indebtedness unless our consolidated leverage ratio would be no greater than 6.00 to 1.00 after the incurrence of the indebtedness, (ii) incur liens, (iii) pay dividends or make certain other restricted payments, investments or acquisitions, (iv) enter into certain transactions with affiliates, (v) merge or consolidate with another person, (vi) sell, assign, lease or otherwise dispose of all or substantially all of our assets, and (vii) make voluntary prepayments of certain debt, in each case subject to exceptions.

          Under our debt agreements, the following generally constitute an event of default: (i) a default in the payment of interest; (ii) a default in the payment of principal; (iii) failure to comply with covenants; (iv) failure to pay other indebtedness after final maturity or acceleration of other indebtedness exceeding a specified amount; (v) certain events of bankruptcy; (vi) a judgment for payment of money exceeding a specified aggregate amount; and (vii) voidance of subsidiary guarantees, subject to grace periods where applicable.

          Goodwill represents the excess of the purchase price over the estimated fair value of net tangible and identifiable intangible assets acquired in business combinations. Our annual impairment assessment is performed as of October 1^st of each year, and an assessment is performed at other times if events or circumstances indicate it is more likely than not that the asset is impaired. During the three and six months ended June 30, 2011 and 2010, there were no indicators of impairment and no impairment loss was recorded to our goodwill.

(1)	Includes captial lease obligations.
(2)	The table does not include our reserve for uncertain taxes, which at June 30, 2011 totaled $1,496, as the specific timing of any cash payments relating to this obligation cannot be projected with reasonable certainty.

          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.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Summary of Significant Accounting Policies [Abstract]

Principles of Consolidation

     Principles of Consolidation

          The accompanying unaudited consolidated financial statements of Sirius XM Radio Inc. and subsidiaries have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), the instructions to Form 10-Q and Article 10 of Regulation S-X of the United States Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, these interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. All significant intercompany transactions have been eliminated in consolidation.

Basis of Presentation

     Basis of Presentation

          In the opinion of management, all normal recurring adjustments necessary for the fair presentation of our unaudited consolidated financial statements as of June 30, 2011 and for the three and six months ended June 30, 2011 and 2010 have been made.

          Interim results are not necessarily indicative of the results that may be expected for a full year. This Quarterly Report on Form 10-Q should be read together with our Annual Report on Form 10-K for the year ended December 31, 2010, which was filed with the SEC on February 16, 2011.

          We have evaluated events subsequent to the balance sheet date and prior to the filing of this Quarterly Report on Form 10-Q for the three and six months ended June 30, 2011 and have determined that no events have occurred that would require adjustment to our unaudited consolidated financial statements.

Use of Estimates

     Use of Estimates

          In presenting unaudited consolidated financial statements, management makes estimates and assumptions that affect the reported amounts and accompanying notes. Estimates, by their nature, are based on judgment and available information at this time. Actual results could differ materially from those estimates.

          Significant estimates inherent in the preparation of the accompanying unaudited consolidated financial statements include revenue recognition, asset impairment, useful lives of our satellites, share-based payment expense, and valuation allowances against deferred tax assets. Economic conditions in the United States could have a material impact on our accounting estimates.

Recent Accounting Pronouncements

     Recent Accounting Pronouncements

          In May 2011, the FASB issued Accounting Standards Update No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (Topic 820) — Fair Value Measurement (ASU 2011-04), to provide a consistent definition of fair value and ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and International Financial Reporting Standards. ASU 2011-04 changes certain fair value measurement principles and enhances the disclosure requirements particularly for level 3 fair value measurements. The amendments are not expected to have a significant impact on companies that apply U.S. GAAP. This standard is effective for interim and annual periods beginning after December 15, 2011 and will be applied prospectively. We are currently evaluating the impact of our pending adoption of ASU 2011-04 on our consolidated financial statements.

          In June 2011, the FASB issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220) — Presentation of Comprehensive Income (ASU 2011-05), to require an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of equity. The standard does not change the items which must be reported in other comprehensive income, how such items are measured or when they must be reclassified to net income. This standard is effective for interim and annual periods beginning after December 15, 2011 and will be applied retrospectively. ASU 2011-05 affects financial statement presentation only and will have no impact on our results of operations.

Earnings per Share

     Earnings per Share (“EPS”)

          Basic net income per common share is calculated using the weighted average common shares outstanding during each reporting period. Diluted net income per common share adjusts the weighted average common shares outstanding for the potential dilution that could occur if common stock equivalents (convertible debt and preferred stock, warrants, stock options, restricted stock and restricted stock units) were exercised or converted into common stock, calculated using the treasury stock method. Common stock equivalents of approximately 96,155,764 and 686,407,346 for the three months ended June 30, 2011 and 2010, respectively, and 109,334,669 and 692,011,065 for the six months ended June 30, 2011 and 2010, respectively, were excluded from the calculation of diluted net income per common share as the effect would have been anti-dilutive.

Accounts Receivable

     Accounts Receivable

          Accounts receivable, net, is stated at amounts due from customers net of an allowance for doubtful accounts. Our allowance for doubtful accounts considers historical experience, the age of amounts due, current economic conditions and other factors that may affect the counterparty’s ability to pay.

Inventory

     Inventory

          Inventory consists of finished goods, refurbished goods, chip sets and other raw material components used in manufacturing radios. Inventory is stated at the lower of cost, determined on a first-in, first-out or market basis. We record an estimated allowance for inventory that is considered slow moving, obsolete or whose carrying value is in excess of net realizable value. The provision related to products purchased for resale in our direct to consumer distribution channel and components held for resale by us is reported as a component of Cost of equipment in our unaudited consolidated statements of operations. The provision related to inventory consumed in our OEM and retail distribution channel is reported as a component of Subscriber acquisition costs in our unaudited consolidated statements of operations.

Fair Value of Financial Instruments

     Fair Value of Financial Instruments

          The fair value of a financial instrument is the amount at which the instrument could be exchanged in an orderly transaction between market participants to sell the asset or transfer the liability. As of June 30, 2011 and December 31, 2010, the carrying amounts of cash and cash equivalents, accounts and other receivables, and accounts payable approximated fair value due to the short-term nature of these instruments.

          The fair value for publicly traded instruments is determined using quoted market prices while the fair value for non-publicly traded instruments is based upon estimates from a market maker and brokerage firm. As of June 30, 2011 and December 31, 2010, the carrying value of our debt was $3,024,960 and $3,217,578, respectively; and the fair value approximated $3,488,874 and $3,722,905, respectively.

Reclassifications

     Reclassifications

          Certain amounts in our prior period consolidated financial statements have been reclassified to conform to our current period presentation.

ASC 605 Revenue Recognition

          In 2005, XM entered into agreements to provide XM Canada with the right to offer XM satellite radio service in Canada. The agreements have an initial ten year term and XM Canada has the unilateral option to extend the agreements for an additional five year term. We receive a 15% royalty for all subscriber fees earned by XM Canada each month for its basic service and an activation fee for each gross activation of an XM Canada subscriber on XM’s system. Sirius XM Canada is obligated to pay us a total of $70,300 for the rights to broadcast and market National Hockey League (“NHL”) games for a ten year term. We recognize these payments on a gross basis as a principal obligor pursuant to the provisions of ASC 605, Revenue Recognition. The estimated fair value of deferred revenue from XM Canada as of the Merger date was approximately $34,000, which is amortized on a straight-line basis through 2020, the end of the expected term of the agreements. As of June 30, 2011 and December 31, 2010, the carrying value of deferred revenue related to this agreement was $27,405 and $28,792, respectively.

* SIRIUS Canada and XM Canada combined in June 2011. The combined entity now operates as Sirius XM Canada.

     Liberty Media

          In February 2009, we entered into an Investment Agreement (the “Investment Agreement”) with an affiliate of Liberty Media Corporation, Liberty Radio, LLC (collectively, “Liberty Media”). Pursuant to the Investment Agreement, in March 2009 we issued to Liberty Radio, LLC 12,500,000 shares of our Convertible Perpetual Preferred Stock, Series B-1 (the “Series B Preferred Stock”), with a liquidation preference of $0.001 per share in partial consideration for certain loan investments. Liberty Media has representatives on our board of directors.

          The Series B Preferred Stock is convertible into 2,586,976,000 shares of common stock. Liberty Media has agreed not to acquire more than 49.9% of our outstanding common stock prior to March 2012, except that Liberty Media may acquire more than 49.9% of our outstanding common stock at any time pursuant to any cash tender offer for all of the outstanding shares of our common stock that are not beneficially owned by Liberty Media or its affiliates at a price per share greater than the closing price of the common stock on the trading day preceding the earlier of the public announcement or commencement of such tender offer. The Investment Agreement also provides for certain other standstill provisions ending in March 2012.

          Liberty Media has advised us that as of June 30, 2011 and December 31, 2010, respectively, it owned the following amounts of our debt securities:

	June 30,		December 31,
	2011		2010
8.75% Senior Notes due 2015	$	150,000	$	150,000
9.75% Senior Secured Notes due 2015		50,000		50,000
13% Senior Notes due 2013		76,000		76,000
7% Exchangeable Senior Subordinated Notes due 2014		11,000		11,000

Less: discounts		9,704		11,093
Total carrying value debt	$	327,296	$	325,907

          As of June 30, 2011 and December 31, 2010, we recorded $9,723 and $9,765, respectively, related to accrued interest with Liberty Media to Related party current liabilities. We recognized Interest expense associated with debt held by Liberty Media of $8,851 and $10,902 for the three months ended June 30, 2011 and 2010, respectively, and $17,784 and $19,964 for the six months ended June 30, 2011 and 2010, respectively.

     Sirius XM Canada

          In June 2011, Canadian Satellite Radio Holdings Inc. (“CSR”), the parent company of XM Canada, and SIRIUS Canada completed a transaction to combine their operations (“the Canada Merger”). As a result of the Canada merger, SIRIUS Canada is a wholly-owned subsidiary of CSR. The combined company will operate as Sirius XM Canada. In connection with the transaction, we received:

• approximately 46,700,000 Class A shares of CSR, representing a 38.0% equity interest and a 25.0% voting interest;

• $53,781 in cash as repayment of the XM Canada credit facility ($38,815) and consideration for our preferred stock in SIRIUS Canada ($10,117 as a return of capital and $4,849 in dividends); and

• approximately $4,100 in non-interest bearing notes of CSR, which primarily have a two year term.

          Our interest in Sirius XM Canada will be accounted for under the equity method. The transaction was accounted for as a reverse acquisition whereby SIRIUS Canada was deemed to be the acquirer of CSR. As a result of the transaction, we recognized an $83,718 gain in Interest and investment income during the three months ended June 30, 2011.

          The excess of the cost of our ownership interest in the equity of Sirius XM Canada over our share of the net assets is recognized as goodwill and intangible assets and is included in the carrying amount of our investment. Equity method goodwill is not amortized. We will periodically evaluate this investment to determine if there has been an other than temporary decline below carrying value. Equity method intangible assets are amortized over their respective useful lives, which is recorded in Interest and investment income. As of June 30, 2011, our investment balance in Sirius XM Canada was approximately $54,800, $30,000 of which represents equity method goodwill and intangible assets, and was recorded in Related party long-term assets. Sirius XM Canada is still evaluating the fair value allocation between goodwill and intangible assets; the final purchase price allocation is not expected to have a material effect on our financial statements.

          We provide Sirius XM Canada with chipsets and other services and we are reimbursed for these costs. As of June 30, 2011, amounts due for these costs totaled $6,264 and is reported as Related party current assets.

          As of June 30, 2011, amounts due from Sirius XM Canada also included $7,576 attributable to deferred programming costs and accrued interest, all of which is reported as Related party long-term assets.

          We hold an investment in Cdn$4,000 face value of 8% convertible unsecured subordinated debentures issued by XM Canada and assumed by Sirius XM Canada, for which the embedded conversion feature is bifurcated from the host contract. The host contract is accounted for at fair value as an available-for-sale security with changes in fair value recorded to Accumulated other comprehensive loss, net of tax. The embedded conversion feature is accounted for at fair value as a derivative with changes in fair value recorded in earnings as Interest and investment income (loss). As of June 30, 2011, the carrying values of the host contract and embedded derivative related to our investment in the debentures was $3,537 and $4, respectively. As of December 31, 2010, the carrying values of the host contract and embedded derivative related to our investment in the debentures was $3,302 and $11, respectively. The carrying values of the host contract and embedded derivative are recorded in Related party long-term assets.

          Our share of net earnings or losses of Sirius XM Canada will be recorded to Interest and investment income (loss) in our unaudited consolidated statements of operations on a one month lag.

     SIRIUS Canada

          We had an equity interest of 49.9% in SIRIUS Canada until June 21, 2011 when the transaction between XM Canada and SIRIUS Canada closed. Our investment balance was zero as of December 31, 2010 as our investment balance was absorbed by our share of net losses generated by SIRIUS Canada.

          In 2005, we entered into a license and services agreement with SIRIUS Canada. Pursuant to such agreement, we are reimbursed for certain costs incurred to provide SIRIUS Canada service, including certain costs incurred for the production and distribution of radios, as well as information technology support costs. In consideration for the rights granted pursuant to this license and services agreement, we have the right to receive a royalty equal to a percentage of SIRIUS Canada’s gross revenues based on subscriber levels (ranging between 5% to 15%) and the number of Canadian-specific channels made available to SIRIUS Canada.

          We recorded the following revenue from SIRIUS Canada. Royalty income is included in other revenue and dividend income is included in Interest and investment income (loss) in our unaudited consolidated statements of operations:

	For the Three Months				For the Six Months
	Ended June 30,				Ended June 30,
	2011*		2010		2011*		2010
Royalty income	$	5,475	$	1,765	$	9,945	$	3,440
Dividend income		222		231		460		457
Total revenue from SIRIUS Canada	$	5,697	$	1,996	$	10,405	$	3,897

* SIRIUS Canada combined with XM Canada in June 2011.

          Receivables from royalty and dividend income were utilized to absorb a portion of our share of net losses generated by SIRIUS Canada during the three and six months ended June 30, 2011 and 2010. Total costs that have been or will be reimbursed by SIRIUS Canada for the three months ended June 30, 2011 and 2010 were $2,763 and $2,393, respectively, and for the six months ended June 30, 2011 and 2010 were $5,253 and $4,835, respectively.

          Our share of net earnings or losses of SIRIUS Canada is recorded to Interest and investment income (loss) in our unaudited consolidated statements of operations on a one month lag. Our share of SIRIUS Canada’s net loss was $5,259 and $1,316 for the three months ended June 30, 2011 and 2010, respectively, and $9,717 and $3,218 for the six months ended June 30, 2011 and 2010, respectively. The payments received from SIRIUS Canada in excess of carrying value was $3,868 and $3,710 for the three months ended June 30, 2011 and 2010, respectively, and $6,748 and $3,710 for the six months ended June 30, 2011 and 2010, respectively.

     XM Canada

          We had an equity interest of 21.5% in XM Canada until June 21, 2011 when transaction between XM Canada and SIRIUS Canada closed. Our investment balance was zero as of December 31, 2010 as our investment balance was absorbed by our share of net losses generated by XM Canada.

          In 2005, XM entered into agreements to provide XM Canada with the right to offer XM satellite radio service in Canada. The agreements have an initial ten year term and XM Canada has the unilateral option to extend the agreements for an additional five year term. We receive a 15% royalty for all subscriber fees earned by XM Canada each month for its basic service and an activation fee for each gross activation of an XM Canada subscriber on XM’s system. Sirius XM Canada is obligated to pay us a total of $70,300 for the rights to broadcast and market National Hockey League (“NHL”) games for a ten year term. We recognize these payments on a gross basis as a principal obligor pursuant to the provisions of ASC 605, Revenue Recognition. The estimated fair value of deferred revenue from XM Canada as of the Merger date was approximately $34,000, which is amortized on a straight-line basis through 2020, the end of the expected term of the agreements. As of June 30, 2011 and December 31, 2010, the carrying value of deferred revenue related to this agreement was $27,405 and $28,792, respectively.

          The Cdn$45,000 standby credit facility we extended to XM Canada was paid and terminated as a result of the Canada Merger. We received $38,815 in cash upon payment of the standby credit facility. As a result of the repayment of the credit facility and completion of the Canada Merger, we released a $15,649 valuation allowance related to the absorption of our share of the net loss from our investment in XM Canada as of June 21, 2011.

          As of December 31, 2010, amounts due from XM Canada also included $7,201 attributable to deferred programming costs and accrued interest, all of which is reported as Related party long-term assets.

          We recorded the following revenue from XM Canada as Other revenue in our unaudited consolidated statements of operations:

	For the Three Months				For the Six Months

	2011*		2010		2011*		2010

     General Motors and American Honda

          We have a long-term distribution agreement with General Motors Company (“GM”). GM had a representative on our board of directors and was considered a related party through May 27, 2010. During the term of the agreement, GM has agreed to distribute the XM service. We subsidize a portion of the cost of satellite radios and make incentive payments to GM when the owners of GM vehicles with factory- or dealer- installed satellite radios become self-paying subscribers. We also share with GM a percentage of the subscriber revenue attributable to GM vehicles with factory- or dealer- installed satellite radios. As part of the agreement, GM provides certain call-center related services directly to subscribers who are also GM customers for which we reimburse GM.

          We make bandwidth available to OnStar LLC for audio and data transmissions to owners of enabled GM vehicles, regardless of whether the owner is a subscriber. OnStar’s use of our bandwidth must be in compliance with applicable laws, must not compete or adversely interfere with our business, and must meet our quality standards. We also granted to OnStar a certain amount of time to use our studios on an annual basis and agreed to provide certain audio content for distribution on OnStar’s services.

          We have a long-term distribution agreement with American Honda. American Honda had a representative on our board of directors and was considered a related party through May 27, 2010. We have an agreement to make a certain amount of our bandwidth available to American Honda. American Honda’s use of our bandwidth must be in compliance with applicable laws, must not compete or adversely interfere with our business, and must meet our quality standards. This agreement remains in effect so long as American Honda holds a certain amount of its investment in us. We make incentive payments to American Honda for each purchaser of a Honda or Acura vehicle that becomes a self-paying subscriber and we share with American Honda a portion of the subscriber revenue attributable to Honda and Acura vehicles with installed satellite radios.

          We recorded the following total related party revenue from GM and American Honda, primarily consisting of subscriber revenue, in connection with the agreements above:

Benefits Plans [Abstract]

Benefits Plans

(13) Benefits Plans

          We recognized share-based payment expense of $10,735 and $15,682 for the three months ended June 30, 2011 and 2010, respectively, and $22,023 and $31,223 for the six months ended June 30, 2011 and 2010, respectively. We did not realize any income tax benefits from share-based benefits plans during the three and six months ended June 30, 2011 and 2010 as a result of the full valuation allowance that is maintained for substantially all net deferred tax assets.

     2009 Long-Term Stock Incentive Plan

          In May 2009, our stockholders approved the Sirius XM Radio Inc. 2009 Long-Term Stock Incentive Plan (the “2009 Plan”). Employees, consultants and members of our board of directors are eligible to receive awards under the 2009 Plan. The 2009 Plan provides for the grant of stock options, restricted stock, restricted stock units and other stock-based awards that the compensation committee of our board of directors may deem appropriate. Vesting and other terms of stock-based awards are set forth in the agreements with the individuals receiving the awards. Stock-based awards granted under the 2009 Plan are generally subject to a vesting requirement. Stock-based awards generally expire ten years from the date of grant. Each restricted stock unit entitles the holder to receive one share of common stock upon vesting. As of June 30, 2011, approximately 271,986,000 shares of common stock were available for future grants under the 2009 Plan.

     Other Plans

          We maintain four other share-based benefit plans — the XM 2007 Stock Incentive Plan, the Amended and Restated Sirius Satellite Radio 2003 Long-Term Stock Incentive Plan, the XM 1998 Shares Award Plan and the XM Talent Option Plan. No further awards may be made under these plans. Outstanding awards under these plans are being continued.

          The following table summarizes the weighted-average assumptions used to compute the fair value of options granted to employees and members of our board of directors:

	For the Three Months						For the Six Months
	Ended June 30,						Ended June 30,
	2011			2010			2011			2010
Risk-free interest rate		1.8	%		2.2	%		1.8	%		2.5	%
Expected life of options — years		5.25			5.11			5.25			5.06
Expected stock price volatility		56	%		86	%		56	%		85	%
Expected dividend yield		0	%		0	%		0	%		0	%

          There were no options granted to third parties during the three and six months ended June 30, 2011 and 2010.

          We estimate fair value of awards granted using the hybrid approach for volatility, which weights observable historical volatility and implied volatility of qualifying actively traded options on our common stock. In 2010, due to the lack of qualifying actively traded options on our common stock, we utilized a 100% weighting to observable historical volatility.

          The following table summarizes stock option activity under our share-based payment plans for the six months ended June 30, 2011 (shares in thousands):

						Weighted-Average
						Remaining		Aggregate
				Weighted-Average		Contractual Term		Intrinsic
	Shares			Exercise Price		(Years)		Value
Outstanding, December 31, 2010		401,870		$	1.32
Granted		719		$	2.33
Exercised		(7,346	)	$	0.94
Forfeited, cancelled or expired		(17,613	)	$	4.30
Outstanding, June 30, 2011		377,630		$	1.19		6.14	$	495,613
Exercisable, June 30, 2011		113,277		$	2.42		4.67	$	90,035

          The weighted average grant date fair value of options granted during the six months ended June 30, 2011 and 2010 was $1.17 and $0.47, respectively. The total intrinsic value of stock options exercised during the six months ended June 30, 2011 and 2010 was $7,393 and $221, respectively.

          We recognized share-based payment expense associated with stock options of $9,920 and $10,254 for the three months ended June 30, 2011 and 2010, respectively, and $19,897 and $20,780 for the six months ended June 30, 2011 and 2010, respectively.

          The following table summarizes the nonvested restricted stock and restricted stock unit activity under our share-based payment plans for the six months ended June 30, 2011 (shares in thousands):

The weighted-average period over which the compensation expense for these awards is expected to be recognized is three years as of June 30, 2011.

     401(k) Savings Plan

          We sponsor the Sirius XM Radio 401(k) Savings Plan (the “Sirius XM Plan”) for eligible employees.

          The Sirius XM Plan allows eligible employees to voluntarily contribute from 1% to 50% of their pre-tax eligible earnings, subject to certain defined limits. We match 50% of an employee’s voluntary contributions, up to 6% of an employee’s pre-tax salary, in the form of shares of common stock. Employer matching contributions under the Sirius XM Plan vest at a rate of 33¹/₃% for each year of employment and are fully vested after three years of employment for all current and future contributions. Share-based payment expense resulting from the matching contribution to the plans was $814 and $718 for the three months ended June 30, 2011 and 2010, respectively, and $1,583 and $1,925 for the six months ended June 30, 2011 and 2010, respectively.

          We may also elect to contribute to the profit sharing portion of the Sirius XM Plan based upon the total eligible compensation of eligible participants. These additional contributions in the form of shares of common stock are determined by the compensation committee of our board of directors. Employees are only eligible to receive profit-sharing contributions during any year in which they are employed on the last day of the year. We currently do not anticipate contributing to the profit sharing portion of the Sirius XM Plan in 2011. Profit-sharing contribution expense was $0 and $2,594 for the three months ended June 30, 2011 and 2010, respectively, and $0 and $3,844 for the six months ended June 30, 2011 and 2010, respectively.
