Principles of Consolidation
Principles of Consolidation

The accompanying 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 a fair presentation of our unaudited consolidated financial statements as of September 30, 2012 and for the three and nine months ended September 30, 2012 and 2011 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, 2011, which was filed with the SEC on February 9, 2012.

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 nine months ended September 30, 2012 and have determined that no events have occurred that would require adjustment to our unaudited consolidated financial statements.

Use of Estimates
Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and footnotes. Estimates, by their nature, are based on judgment and available information. Actual results could differ materially from those estimates.

Significant estimates inherent in the preparation of the accompanying unaudited consolidated financial statements include asset impairment, depreciable lives of our satellites, share-based payment expense, and valuation allowances against deferred tax assets.
Income Taxes
Income Taxes

Income tax expense is the sum of current income tax plus the change in deferred tax assets and liabilities.

Deferred income taxes represent the tax consequences related to temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for tax purposes at each reporting period, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. In determining the period in which related tax benefits are realized for book purposes, excess share-based compensation deductions included in net operating losses are realized after regular net operating losses are exhausted; excess tax compensation benefits are recorded off balance-sheet as a memo entry until the period the excess tax benefit is realized through a reduction of taxes payable. A valuation allowance is recognized or maintained when, based on the weight of all available evidence, it is considered more likely than not that all, or some portion, of the deferred tax assets will not be realized.

ASC 740, Income Taxes, requires a company to first determine whether it is more likely than not that a tax position will be sustained based on its technical merits as of the reporting date, assuming that taxing authorities will examine the position and have full knowledge of all relevant information. A tax position that meets this more likely than not threshold is then measured and recognized at the largest amount of benefit that is greater than fifty percent likely to be realized upon effective settlement with a taxing authority. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We record interest and penalties related to uncertain tax positions in Income tax expense in our unaudited consolidated statements of comprehensive income.

We report revenues net of any tax assessed by a governmental authority that is both imposed on, and concurrent with, a specific revenue-producing transaction between ourselves and a customer in our unaudited consolidated statements of comprehensive income.
Fair Value of Financial Instruments
Fair Value of Financial 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.

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. This standard is effective for interim and annual periods beginning after December 15, 2011 and is applied on a prospective basis. We adopted ASU 2011-04 as of January 1, 2012 and the impact was not material to our unaudited 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 single continuous statements 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 is to be applied retrospectively. The FASB has deferred the requirement to present reclassification adjustments for each component of accumulated other comprehensive income in both net income and other comprehensive income. Companies are required to either present amounts reclassified out of other comprehensive income on the face of the financial statements or disclose those amounts in the notes to the financial statements. During the deferral period, there is no requirement to separately present or disclose the reclassification adjustments into net income. The effective date of this deferral will be consistent with the effective date of ASU 2011-05. We adopted ASU 2011-05 as of January 1, 2012 and disclosed comprehensive income in our unaudited consolidated statements of comprehensive income. ASU 2011-05 affects financial statement presentation and has no impact on our results of unaudited consolidated financial statements.

In July 2012, the FASB issued Accounting Standards Update 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment ("ASU 2012-02"). The guidance gives companies the option to first perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired. If the qualitative assessment supports that it is more likely than not the fair value of the asset exceeds its carrying amount, the company would not be required to perform a quantitative impairment test. If the qualitative assessment does not support the fair value of the asset, then a quantitative assessment is performed. ASU 2012-02 provides for public entities for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. We early adopted ASU 2012-02 and will perform a qualitative assessment to determine whether our indefinite-lived intangible assets are impaired as of October 1, 2012, our annual impairment testing date.
