Our Sirius XM business features music, sports, entertainment, comedy, talk, news, traffic and weather channels and other content, as well as podcasts and infotainment services, in the United States on a subscription fee basis. Sirius XM bundles include live, curated and certain exclusive and on demand programming. The Sirius XM service is distributed through our two proprietary satellite radio systems and streamed via applications for mobile devices, home devices and other consumer electronic equipment. Satellite radios are primarily distributed through automakers, retailers and our website. Our Sirius XM service is also available through our user interface, which we call “360L,” that combines our satellite and streaming services into a single, cohesive in-vehicle entertainment experience.
The primary source of revenue from our Sirius XM business is subscription fees, with most of our customers subscribing to monthly, quarterly, semi-annual or annual plans. We also derive revenue from advertising on select non-music channels, which is sold under the SXM Media brand, direct sales of our satellite radios and accessories, and other ancillary services. As of September 30, 2021, our Sirius XM business had approximately 34.3 million subscribers.
In addition to our audio entertainment businesses, we provide connected vehicle services to several automakers. These services are designed to enhance the safety, security and driving experience of consumers. We also offer a suite of data services that includes graphical weather, fuel prices, sports schedules and scores and movie listings, a traffic information service that includes information as to road closings, traffic flow and incident data to consumers with compatible in-vehicle navigation systems, and real-time weather services in vehicles, boats and planes.
In May 2020, we terminated the Automatic Labs Inc. (“Automatic”) service, which was part of our connected vehicle services business. Automatic operated a service for consumers and auto dealers and offered an install-it-yourself adapter and mobile application, which transformed older vehicles into connected vehicles. During the nine months ended September 30, 2020, we recorded $24 of restructuring expenses in our unaudited consolidated statements of comprehensive income related to this termination of the service. Refer to Note 4 for more information.
Sirius XM also holds a 70% equity interest and 33% voting interest in Sirius XM Canada Holdings Inc. (“Sirius XM Canada”). Sirius XM Canada's subscribers are not included in our subscriber count or subscriber-based operating metrics.
Pandora
Our Pandora business operates a music, comedy and podcast streaming discovery platform, offering a personalized experience for each listener wherever and whenever they want to listen, whether through mobile devices, car speakers or connected devices. Pandora enables listeners to create personalized stations and playlists, discover new content, hear artist- and expert-curated playlists, podcasts and select Sirius XM content as well as search and play songs and albums on-demand. Pandora is available as (1) an ad-supported radio service, (2) a radio subscription service (Pandora Plus) and (3) an on-demand subscription service (Pandora Premium). As of September 30, 2021, Pandora had approximately 6.5 million subscribers.

(Dollars and shares in millions, except per share amounts)
The majority of revenue from our Pandora business is generated from advertising on our Pandora ad-supported radio service which is sold under the SXM Media brand. We also derive subscription revenue from our Pandora Plus and Pandora Premium subscribers.
Our Pandora business also sells advertising on audio platforms and in podcasts unaffiliated with us. Pandora has an arrangement with SoundCloud Holdings, LLC ("SoundCloud") to be its exclusive US ad sales representative. Through this arrangement, Pandora is able to offer advertisers the ability to execute campaigns in the US across the Pandora and SoundCloud listening platforms. We also have arrangements to serve as the ad sales representative for certain podcasts. In addition, through AdsWizz Inc., Pandora provides a comprehensive digital audio and programmatic advertising technology platform, which connects audio publishers and advertisers with a variety of ad insertion, campaign trafficking, yield optimization, programmatic buying, marketplace and podcast monetization solutions.
On February 10, 2020, Sirius XM invested $75 in SoundCloud. SoundCloud is a next-generation music entertainment company, powered by an ecosystem of artists, listeners, and curators on the pulse of what's new, now and next in culture. SoundCloud’s platform enables its users to upload, promote, share and create audio entertainment. The minority investment complements the existing ad sales relationship between SoundCloud and Pandora. Refer to Note 12 for more information on this investment.
On June 16, 2020, Sirius XM acquired Simplecast for $28 in cash. Simplecast is a podcast management and analytics platform. Refer to Note 3 for more information on this acquisition.
On October 16, 2020, Sirius XM acquired certain assets and liabilities of Stitcher from The E.W. Scripps Company and certain of its subsidiaries (“Scripps”) for total consideration of $302, which included $266 in cash and $36 related to the acquisition date fair value of contingent consideration. As of September 30, 2021, we will potentially make up to $30 in additional payments to Scripps related to the contingent consideration based on Stitcher's achievement of certain financial metrics in 2021. During the three and nine months ended September 30, 2021, we recognized a $17 benefit related to the change in fair value of the 2021 portion of the contingent consideration. The acquisition of Stitcher, in conjunction with Simplecast, created a full-service platform for podcast creators, publishers and advertisers. Refer to Note 3 for more information on this acquisition.
Liberty Media
As of September 30, 2021, Liberty Media Corporation (“Liberty Media”) beneficially owned, directly and indirectly, approximately 79% of the outstanding shares of our common stock. As a result, we are a “controlled company” for the purposes of the NASDAQ corporate governance requirements.
Basis of Presentation
The accompanying unaudited consolidated financial statements of Holdings have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). All significant intercompany transactions have been eliminated in consolidation. Certain numbers in our prior period consolidated financial statements and footnotes have been reclassified or consolidated to conform to our current period presentation.
In the opinion of our management, all normal recurring adjustments necessary for a fair presentation of our unaudited consolidated financial statements as of September 30, 2021 and for the three and nine months ended September 30, 2021 and 2020 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, 2020, which was filed with the SEC on February 2, 2021.
Public companies are required to disclose certain information about their reportable operating segments. Operating segments are defined as significant components of an enterprise for which separate financial information is available and is evaluated on a regular basis by the chief operating decision maker in deciding how to allocate resources to an individual segment and in assessing performance of the segment. We have determined that we have two reportable segments as our chief

(Dollars and shares in millions, except per share amounts)
operating decision maker, our Chief Executive Officer, assesses performance and allocates resources based on the financial results of these segments. Refer to Note 18 for information related to our segments.
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, 2021 and have determined that no events have occurred that would require adjustment to our unaudited consolidated financial statements. For a discussion of subsequent events that do not require adjustment to our unaudited consolidated financial statements refer to Note 19.
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 income taxes.
(2)Summary of Significant Accounting Policies
Fair Value Measurements
For assets and liabilities required to be reported at fair value, GAAP provides a hierarchy that prioritizes inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are based on unadjusted quoted prices in active markets for identical instruments. Level 2 inputs are inputs, other than quoted market prices included within Level 1, that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. As of September 30, 2021 and December 31, 2020, the carrying amounts of cash and cash equivalents, receivables and accounts payable approximated fair value due to the short-term nature of these instruments.
Our liabilities measured at fair value were as follows:

| September 30, 2021 |  | December 31, 2020
| Level 1 |  | Level 2 |  | Level 3 |  | Total Fair Value |  | Level 1 |  | Level 2 |  | Level 3 |  | Total Fair Value
Liabilities: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Debt (a) | — |  |  | $ | 9,132 |  |  | — |  |  | $ | 9,132 |  |  | — |  |  | $ | 9,011 |  |  | — |  |  | $ | 9,011 |

(a)The fair value for non-publicly traded debt is based upon estimates from a market maker and brokerage firm. Refer to Note 13 for information related to the carrying value of our debt as of September 30, 2021 and December 31, 2020.
Accumulated Other Comprehensive Income (Loss)
Accumulated other comprehensive income of $17 was primarily comprised of the cumulative foreign currency translation adjustments related to our investment in and loan to Sirius XM Canada (refer to Note 12 for additional information). During the three and nine months ended September 30, 2021, we recorded foreign currency translation adjustment (loss) income of $(10) and $2, respectively, net of tax benefit (expense) of $3 and $(1), respectively. During the three and nine months ended September 30, 2020, we recorded foreign currency translation adjustment income (loss) of $7 and $(8), respectively, net of a tax (expense) benefit of $(2) and $3, respectively.

(3)Acquisitions
Stitcher
On October 16, 2020, Sirius XM acquired certain assets and liabilities of Stitcher from Scripps for $266 in cash, which amount includes net working capital adjustments. The total purchase consideration of $302 includes $36 related to the acquisition date fair value of the contingent consideration. As of September 30, 2021, we will potentially make up to $30 in additional payments to Scripps related to the contingent consideration based on Stitcher's achievement of certain financial metrics in 2021. During the three and nine months ended September 30, 2021, we recognized a $17 benefit related to the change in fair value of the 2021 portion of the contingent consideration in Impairment, restructuring and acquisition costs on our unaudited consolidated statements of comprehensive income. The fair value of the contingent consideration was determined using a probability-weighted cash flow model and will be remeasured to fair value at each subsequent reporting period. Stitcher is included in our Pandora reporting unit.
The table below summarizes the fair value of the assets acquired and liabilities assumed as of the acquisition date:

Acquired Assets: |
Receivables, net | $ | 21 |
Prepaid expenses and other current assets | 16 |
Property and equipment | 8 |
Intangible assets | 38 |
Goodwill | 224 |
Operating lease right-of-use assets | 11 |
Total assets | 318 |
Assumed Liabilities: |
Accounts payable and accrued expenses | 4 |
Deferred revenue | 1 |
Operating lease current liabilities | 2 |
Operating lease liabilities | 9 |
Total liabilities | 16 |
Total consideration | $ | 302 |

The Stitcher acquisition was accounted for using the acquisition method of accounting and was financed through borrowings under our Credit Facility.
Simplecast
On June 16, 2020, Sirius XM acquired Simplecast for $28 in cash. Simplecast is a podcast management and analytics platform. Simplecast complements AdsWizz's advertising technology platform, allowing the company to offer podcasters of all sizes a powerful, comprehensive solution for publishing, analytics, distribution and advertising sales, and is included in the Pandora reporting unit. The Simplecast acquisition was accounted for using the acquisition method of accounting. We recognized goodwill of $17, amortizable intangible assets of $12, other assets of less than $1 and deferred tax liabilities of $1.
Other acquisitions
On April 23, 2021, we completed a small acquisition for total consideration of $27 which includes $20 in cash, a $3 deferred cash payment and $4 in restricted stock units. We recognized goodwill of $22 and other assets of $5.
Acquisition related costs of $3 were recognized for the nine months ended September 30, 2021.

(4)Restructuring Costs
During the nine months ended September 30, 2021, we evaluated our office space needs and, as a result of such analysis, surrendered certain office leases primarily in New York, New York and Oakland, California. We assessed the recoverability of the carrying value of the operating lease right of use assets related to these locations. Based on that assessment, the carrying values of the assets were not recoverable and we recorded an impairment of $18 to reduce the carrying value of the assets to their fair values. Additionally, we accrued expenses of $6 for which we will not recognize any future economic benefits and wrote off leasehold improvements of $1. The fair values of the assets were determined using a discounted cash flow model based on management's assumptions regarding the ability to sublease the locations and the remaining term of the leases. The total charge of $25 was recorded to Impairment, restructuring and acquisition costs in our unaudited consolidated statement of comprehensive income for the nine months ended September 30, 2021. There were no restructuring charges recorded during the three months ended September 30, 2021.
In May 2020, we terminated the Automatic service, which was part of our connected services business. During the nine months ended September 30, 2020, we recorded $24 of restructuring expenses primarily related to the write down of property and equipment, definite lived intangible assets and certain other assets in Acquisition and restructuring costs in our unaudited consolidated statements of comprehensive income. We did not record any restructuring expenses during the three months ended September 30, 2020. The termination of the Automatic service does not meet the requirements to be reported as a discontinued operation in our unaudited consolidated statements of comprehensive income because the termination of the service does not represent a strategic shift that will have a major effect on our operations and financial results.
(5)Earnings per Share
Basic net income per common share is calculated by dividing the income available to common stockholders by the weighted average common shares outstanding during each reporting period. Diluted net income per common share adjusts the weighted average number of common shares outstanding for the potential dilution that could occur if common stock equivalents (stock options, restricted stock units and convertible debt) were exercised or converted into common stock, calculated using the treasury stock method. We had no participating securities during the three and nine months ended September 30, 2021 and 2020.

(6)Receivables, net
Receivables, net, includes customer accounts receivable, receivables from distributors and other receivables. We do not have any customer receivables that individually represent more than ten percent of our receivables.
Customer accounts receivable, net, includes receivables from our subscribers and advertising customers, including advertising agencies and other customers, and is stated at amounts due, net of an allowance for doubtful accounts. Our allowance for doubtful accounts is based upon our assessment of various factors. We consider historical experience, the age of the receivable balances, current economic conditions, industry experience and other factors that may affect the counterparty’s ability to pay. Bad debt expense is included in Customer service and billing expense in our unaudited consolidated statements of comprehensive income.
Receivables from distributors primarily include billed and unbilled amounts due from automakers for services included in the sale or lease price of vehicles, as well as billed amounts due from wholesale distributors of our satellite radios. Other receivables primarily include amounts due from manufacturers of our radios, modules and chipsets where we are entitled to subsidies and royalties based on the number of units produced. We have not established an allowance for doubtful accounts for our receivables from distributors or other receivables as we have historically not experienced any significant collection issues with automakers or other third parties and do not expect issues in the foreseeable future.

(7)Inventory, net
Inventory consists of finished goods and refurbished goods. Inventory is stated at the lower of cost or market. We record an estimated allowance for inventory that is considered slow moving or 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 comprehensive income. The provision related to inventory consumed in our OEM channel is reported as a component of Subscriber acquisition costs in our unaudited consolidated statements of comprehensive income.
Inventory, net, consists of the following:

| September 30, 2021 |  | December 31, 2020
Finished goods | $ | 7 |  |  | $ | 13 |
Allowance for obsolescence | (3) |  |  | (3) |
Total inventory, net | $ | 4 |  |  | $ | 10 |

(8)Goodwill
Goodwill represents the excess of the purchase price over the estimated fair value of the net tangible and identifiable intangible assets acquired in business combinations. Our annual impairment assessment of our two reporting units is performed as of the fourth quarter of each year, and an assessment is performed at other times if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. ASC 350, Intangibles - Goodwill and Other, states that an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. ASC 350 also states that a reporting unit with a zero or negative carrying amount is not required to perform a qualitative assessment. Our Sirius XM reporting unit, which has an allocated goodwill balance of $2,290, had a negative carrying amount as of September 30, 2021.
As of September 30, 2021, there were no indicators of impairment, and no impairment losses were recorded for goodwill during the three and nine months ended September 30, 2021 and 2020. As of September 30, 2021, the cumulative balance of goodwill impairments recorded was $5,722, of which $4,766 was recognized during the year ended December 31, 2008 and is included in the carrying amount of the goodwill allocated to our Sirius XM reporting unit and $956 was recognized during the year ended December 31, 2020 and is included in the carrying amount of the goodwill allocated to our Pandora reporting unit.
As of September 30, 2021, the carrying amount of goodwill for our Sirius XM and Pandora reporting units was $2,290 and $860, respectively. During the nine months ended September 30, 2021, we recorded $6 of goodwill related to purchase accounting adjustments for the acquisition of Stitcher and $22 of goodwill related to a small acquisition which was recorded to our Pandora reporting unit. As of December 31, 2020, the carrying amount of goodwill for our Sirius XM and Pandora reporting units was $2,290 and $832, respectively.

Indefinite Life Intangible Assets
We have identified our FCC licenses and XM and Pandora trademarks 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. Each of the FCC licenses authorizes us to use radio spectrum, a reusable resource that does not deplete or exhaust over time.
Our annual impairment assessment of our identifiable indefinite lived intangible assets is performed as of the fourth quarter of each year. An assessment is performed at other times if an event occurs or circumstances change that would more likely than not reduce the fair value of the asset below its carrying value. If the carrying value of the intangible assets exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. As of September 30, 2021, there were no indicators of impairment, and no impairment loss was recognized for intangible assets with indefinite lives during the three and nine months ended September 30, 2021. During the nine months ended September 30, 2020, we recognized an impairment loss of less than $1 for intangible assets with indefinite lives related to the termination of the Automatic service. No impairment loss was recognized during the three months ended September 30, 2020.
Definite Life Intangible Assets
Amortization expense for all definite life intangible assets was $38 and $37 for the three months ended September 30, 2021 and 2020, respectively, and $115 and $113 for the nine months ended September 30, 2021 and 2020, respectively. There were retirements of definite lived intangible assets of $17, which included a loss of $4, due to the termination of the Automatic service, during the nine months ended September 30, 2020. There were no retirements of definite lived intangible assets during the nine months ended September 30, 2021.

There were no retirements of property and equipment during the three months ended September 30, 2020.
We capitalize a portion of the interest on funds borrowed to finance the construction and launch of our satellites. Capitalized interest is recorded as part of the asset’s cost and depreciated over the satellite’s useful life. Capitalized interest costs were and $1 and $5 for the three months ended September 30, 2021 and 2020, respectively, and $6 and $14 for the nine

months ended September 30, 2021 and 2020, respectively, which related to the construction of our SXM-8 satellite. We also capitalize a portion of share-based compensation related to employee time for capitalized software projects. Capitalized share-based compensation costs were $4 for each of the three months ended September 30, 2021 and 2020 and $10 and $13 for the nine months ended September 30, 2021 and 2020, respectively.
Satellites
As of September 30, 2021, we operated a fleet of six satellites. Each satellite requires an FCC license, and prior to the expiration of each license, we are required to apply for a renewal of the FCC satellite license. The renewal and extension of our licenses is reasonably certain at minimal cost, which is expensed as incurred. The chart below provides certain information on our satellites as of September 30, 2021:

Satellite Description |  | Year Delivered |  | Estimated End of Depreciable Life |  | FCC License Expiration Year
SIRIUS FM-5 |  | 2009 |  | 2024 |  | 2025
SIRIUS FM-6 |  | 2013 |  | 2028 |  | 2022
XM-3 |  | 2005 |  | 2020 |  | 2026
XM-4 |  | 2006 |  | 2021 |  | 2022
XM-5 |  | 2010 |  | 2025 |  | 2026
SXM-8 |  | 2021 |  | 2036 |  | 2029

On December 13, 2020, our SXM-7 satellite was launched and in-orbit testing of SXM-7 began on January 4, 2021. During in-orbit testing of SXM-7, events occurred which caused failures of certain SXM-7 payload units. The evaluation of SXM-7 concluded that the satellite will not function as intended, which we considered to be a triggering event prompting the assessment as to whether the asset's carrying value of $220 was recoverable. In determining recoverability of SXM-7, we compared the asset's carrying value to the undiscounted cash flows derived from the satellite. SXM-7 was determined to be a total loss and therefore, we determined that the carrying value of the satellite is not recoverable and an impairment charge of $220 was recorded to Impairment, restructuring and acquisition costs in our unaudited consolidated statements of comprehensive income for the nine months ended September 30, 2021. SXM-7 remains in-orbit at its assigned orbital location, but is not being used to provide satellite radio service.
We procured insurance for SXM-7 to cover the risks associated with the satellite's launch and first year of in-orbit operation. The aggregate coverage under the insurance policies with respect to SXM-7 is $225. During the nine months ended September 30, 2021, we collected $225 of insurance recoveries. Of this amount, $80 and $220 have been recorded as a reduction to Impairment, restructuring and acquisition costs during the three and nine months ended September 30, 2021, respectively. The remaining $5 has been recorded in Other income during the three and nine months ended September 30, 2021.
Our SXM-8 satellite was successfully launched into a geostationary orbit on June 6, 2021 and was placed into service on September 8, 2021 following the completion of in-orbit testing. The SXM-8 satellite replaced the XM-3 satellite, which remains available as an in-orbit spare along with XM-5.
(11)Leases
We have operating and finance leases for offices, terrestrial repeaters, data centers and certain equipment. Our leases have remaining lease terms of less than 1 year to 17 years, some of which may include options to extend the leases for up to 5 years, and some of which may include options to terminate the leases within 1 year. We elected the practical expedient to account for the lease and non-lease components as a single component. Additionally, we elected the practical expedient to not recognize right-of-use assets or lease liabilities for short-term leases, which are those leases with a term of twelve months or less at the lease commencement date.

(b)All material domestic subsidiaries, including Pandora and its subsidiaries, that guarantee the Credit Facility have guaranteed these notes.
(c)Holdings has unconditionally guaranteed all of the payment obligations of Pandora under these notes.
(d)We acquired $193 in principal amount of the 1.75% Convertible Senior Notes due 2023 as part of the acquisition of Pandora Media, Inc. in 2019. We allocate the principal amount of the 1.75% Convertible Senior Notes due 2023 between the liability and equity components. The value assigned to the debt components of the 1.75% Convertible Senior Notes due 2023 is the estimated fair value as of the issuance date of similar debt without the conversion feature. The difference between the fair value of the debt and this estimated fair value represents the value which has been assigned to the equity component. The equity component is recorded to additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the Notes over the carrying amount of the liability component is recorded as a debt discount and is being amortized to interest expense using the effective interest method through the December 1, 2023 maturity date. The 1.75% Convertible Senior Notes due 2023 were not convertible into common stock and not redeemable as of September 30, 2021. As a result, we have classified the debt as Long-term within our unaudited consolidated balance sheets.
(e)In August 2021, Sirius XM entered into an amendment to extend the maturity of the $1,750 Credit Facility to August 31, 2026. Sirius XM's obligations under the Credit Facility are guaranteed by certain of its material domestic subsidiaries, including Pandora and its subsidiaries, and are secured by a lien on substantially all of Sirius XM's assets and the assets of its material domestic subsidiaries. Interest on borrowings is payable on a monthly basis and accrues at a rate based on LIBOR plus an applicable rate. Sirius XM is also required to pay a variable fee on the average daily unused portion of the Credit Facility which is payable on a

quarterly basis. The variable rate for the unused portion of the Credit Facility was 0.25% per annum as of September 30, 2021. All of Sirius XM's outstanding borrowings under the Credit Facility are classified as Long-term debt within our unaudited consolidated balance sheets due to the long-term maturity of this debt. Additionally, the amount available for future borrowing under the Credit Facility is reduced by letters of credit issued for the benefit of Pandora, which were $1 as of September 30, 2021.
(f)On August 2, 2021, Sirius XM redeemed $1,000 in outstanding principal amount of the 3.875% Senior Notes due 2022 for an aggregate purchase price, including interest, of $1,019.

On September 2, 2021, Sirius XM redeemed $1,000 in outstanding principal amount of the 5.375% Senior Notes due 2026 for an aggregate purchase price, including premium and interest, of $1,034. During the three and nine months ended September 30, 2021, we recognized $83 to Loss on extinguishment of debt, consisting primarily of redemption premiums of $62, unamortized discount and unamortized deferred financing fees, as a result of these redemptions.
(g)On August 16, 2021, Sirius XM issued $1,000 aggregate principal amount of the 3.125% Senior Notes due 2026 and $1,500 aggregate principal amount of the 3.875% Senior Notes due 2031 with a net original issuance discount and deferred financing costs in aggregate of $13 and $19, respectively.
Retired Debt

On July 9, 2020, Sirius XM also redeemed $1,000 of its then outstanding 5.375% Senior Notes due 2025 for an aggregate purchase price, including premium and interest, of $1,039. During the three and nine months ended September 30, 2020, we recognized $40 to Loss on extinguishment of debt, consisting primarily of redemption premiums, unamortized discount and deferred financing fees, as a result of these redemptions.
Covenants and Restrictions
Under the Credit Facility, Sirius XM, our wholly owned subsidiary, must comply with a debt maintenance covenant that it cannot exceed a total leverage ratio, calculated as consolidated total debt to consolidated operating cash flow, of 5.0 to 1.0. The Credit Facility generally requires compliance with certain covenants that restrict Sirius XM's ability to, among other things, (i) incur additional 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 Sirius XM's assets, and (vii) make voluntary prepayments of certain debt, in each case subject to exceptions.
The indentures governing Sirius XM's notes restrict Sirius XM's non-guarantor subsidiaries' ability to create, assume, incur or guarantee additional indebtedness without such non-guarantor subsidiary guaranteeing each such series of notes on a pari passu basis. The indentures governing the notes also contain covenants that, among other things, limit Sirius XM's ability and the ability of its subsidiaries to create certain liens; enter into sale/leaseback transactions; and merge or consolidate.
Under Sirius XM's 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. If an event of default occurs and is continuing, our debt could become immediately due and payable.
The indenture governing the Pandora 2023 Notes (as defined below) contains covenants that limit Pandora’s ability to merge or consolidate and provides for customary events of default, which include nonpayment of principal or interest, breach of covenants, payment defaults or acceleration of other indebtedness and certain events of bankruptcy.
At September 30, 2021 and December 31, 2020, we were in compliance with our debt covenants.

2015 Long-Term Stock Incentive Plan

24

(Dollars and shares in millions, except per share amounts)
2015 Plan provides for the grant of stock options, restricted stock awards, restricted stock units and other stock-based awards that the Compensation Committee of our Board of Directors deems appropriate. Stock-based awards granted under the 2015 Plan are generally subject to a graded vesting requirement, which is generally three to four years from the grant date. Stock options generally expire ten years from the date of grant. Restricted stock units include performance-based restricted stock units (“PRSUs”), the vesting of which are subject to the achievement of performance goals and the employee's continued employment and generally cliff vest on the third anniversary of the grant date. Each restricted stock unit entitles the holder to receive one share of common stock upon vesting. As of September 30, 2021, 128 shares of common stock were available for future grants under the 2015 Plan.
In February 2021, the Compensation Committee of our Board of Directors approved a modification to the design of our long-term equity compensation program for our senior management. The Compensation Committee intends to award equity-based compensation to our senior management in the form of: 25% stock options, which awards will vest in installments on the first three anniversaries of the date of grant; 25% restricted stock units, which awards will vest in installments on the first three anniversaries of the date of grant; 25% PRSUs, which will cliff vest on the third anniversary of the date of grant after a two-year performance period if the free cash flow target established by the Compensation Committee is achieved; and 25% PRSUs, which will cliff vest after a three-year performance period based on the performance of our common stock relative to the companies included in the S&P 500 Index. We refer to this performance measure as a relative “TSR” or “total stockholder return” metric. PRSUs based on the relative total stockholder return metric will only vest if our performance achieves at least the 25th percentile, with a target payout requiring performance at the 50th percentile. The settlement of PRSUs earned in respect of the applicable three-year performance period will be generally subject to the executive’s continued employment with us through the date the total stockholder return performance is certified by the Compensation Committee.
In connection with our February 2019 acquisition of Pandora, we assumed all shares available for issuance (including any shares that later become available for issuance in accordance with the terms of the applicable plans) under each of the 2014 Stock Incentive Plan of AdsWizz Inc., the Pandora Media, Inc. 2011 Equity Incentive Plan, the Pandora Media, Inc. 2004 Stock Plan and the TheSavageBeast.com, Inc. 2000 Stock Incentive Plan, which were previously approved by stockholders of Pandora or the applicable adopting entity. All shares available under these stock plans became additional shares available for grant pursuant to the terms of the 2015 Plan (as adjusted, to the extent appropriate, to reflect the application of the exchange ratio). Subject to certain limitations set forth in the 2015 Plan, such shares may be used for awards under the 2015 Plan.
Other Plans
We maintain six share-based benefit plans in addition to the 2015 Plan — the Sirius XM Radio Inc. 2009 Long-Term Stock Incentive Plan, the Amended and Restated Sirius Satellite Radio 2003 Long-Term Stock Incentive Plan, the 2014 Stock Incentive Plan of AdsWizz Inc., the Pandora Media, Inc. 2011 Equity Incentive Plan, the Pandora Media, Inc. 2004 Stock Plan and the TheSavageBeast.com, Inc. 2000 Stock Incentive Plan. Excluding dividend equivalent units granted as a result of a declared dividend, no further awards may be made under these plans.
The following table summarizes the weighted-average assumptions used to compute the fair value of options granted to employees, members of our board of directors and non-employees:

The following table summarizes stock option activity under our share-based plans for the nine months ended September 30, 2021:

| Options |  | Weighted-Average Exercise Price Per Share |  | Weighted-Average Remaining Contractual Term (Years) |  | Aggregate Intrinsic Value
Outstanding as of December 31, 2020 | 184 |  |  | $ | 4.73 |  |  |  |  |

Outstanding as of September 30, 2021 | 170 |  |  | $ | 5.40 |  |  | 5.85 |  | $ | 144 |
Exercisable as of September 30, 2021 | 99 |  |  | $ | 4.80 |  |  | 4.79 |  | $ | 142 |

The weighted average grant date fair value per stock option granted during the nine months ended September 30, 2021 was $1.77. The total intrinsic value of stock options exercised during the nine months ended September 30, 2021 and 2020 was $149 and $53, respectively. During the nine months ended September 30, 2021, the number of net settled shares issued as a result of stock option exercises was 20.
We recognized share-based payment expense associated with stock options of $10 and $11 for the three months ended September 30, 2021 and 2020, respectively, and $32 and $34 for the nine months ended September 30, 2021 and 2020, respectively.
The following table summarizes the restricted stock unit, including PRSU, activity under our share-based plans for the nine months ended September 30, 2021:

| Shares |  | Grant Date Fair Value Per Share
Nonvested as of December 31, 2020 | 75 |  |  | $ | 6.06 |
Granted | 39 |  |  | $ | 6.35 |
Vested | (24) |  |  | $ | 6.02 |
Forfeited | (8) |  |  | $ | 6.09 |
Nonvested as of September 30, 2021 | 82 |  |  | $ | 6.21 |

The total intrinsic value of restricted stock units, including PRSUs, vesting during the nine months ended September 30, 2021 and 2020 was $154 and $168, respectively. During the nine months ended September 30, 2021, the number of net settled shares issued as a result of restricted stock units vesting totaled 15. During the nine months ended September 30, 2021, we granted 7 PRSUs to certain employees. We believe it is probable that the performance target applicable to these PRSUs will be achieved.
In connection with the cash dividends paid during the nine months ended September 30, 2021, we granted less than 1 restricted stock units, including PRSUs, in accordance with the terms of existing award agreements. These grants did not result in any additional incremental share-based payment expense being recognized during the nine months ended September 30, 2021.
We recognized share-based payment expense associated with restricted stock units, including PRSUs, of $41 and $47 for the three months ended September 30, 2021 and 2020, respectively, and $117 and $131 for the nine months ended September 30, 2021 and 2020, respectively.
Total unrecognized compensation costs related to unvested share-based payment awards for stock options and restricted stock units, including PRSUs, granted to employees, members of our board of directors and third parties at September 30, 2021 and December 31, 2020 was $513 and $385, respectively. The total unrecognized compensation costs at September 30, 2021 are expected to be recognized over a weighted-average period of 2.6 years.

401(k) Savings Plans
Sirius XM Radio Inc. 401(k) Savings Plan
Sirius XM sponsors the Sirius XM Radio Inc. 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 per pay period on the first 6% of an employee’s pre-tax salary up to a maximum of 3% of eligible compensation. We may also make additional discretionary matching, true-up matching and non-elective contributions to the Sirius XM Plan. Employer matching contributions under the Sirius XM Plan vest at a rate of 33.33% for each year of employment and are fully vested after three years of employment for all current and future contributions. Our cash employer matching contributions are not used to purchase shares of our common stock on the open market, unless the employee elects our common stock as their investment option for this contribution. In October 2020, the Pandora Media, LLC 401(k) Profit Sharing Plan and Trust merged with the Sirius XM Plan.
We recognized expenses of $4 for each of the three months ended September 30, 2021 and 2020, and $17 and $12 for the nine months ended September 30, 2021 and 2020, respectively, in connection with the Sirius XM and Pandora Plans.
Sirius XM Holdings Inc. Deferred Compensation Plan
The Sirius XM Holdings Inc. Deferred Compensation Plan (the “DCP”) allows members of our board of directors and certain eligible employees to defer all or a portion of their base salary, cash incentive compensation and/or board of directors’ cash compensation, as applicable. Pursuant to the terms of the DCP, we may elect to make additional contributions beyond amounts deferred by participants, but we are under no obligation to do so. We have established a grantor (or “rabbi”) trust to facilitate the payment of our obligations under the DCP.
Contributions to the DCP, net of withdrawals, were less than $1 and $1 for the three months ended September 30, 2021 and 2020, respectively, and $3 and $8 for the nine months ended September 30, 2021 and 2020, respectively. As of September 30, 2021 and December 31, 2020, the fair value of the investments held in the trust were $53 and $46, respectively, which is included in Other long-term assets in our unaudited consolidated balance sheets and classified as trading securities. Trading gains and losses associated with these investments are recorded in Other (expense) income within our unaudited consolidated statements of comprehensive income. The associated liability is recorded within Other long-term liabilities in our unaudited consolidated balance sheets, and any increase or decrease in the liability is recorded in General and administrative expense within our unaudited consolidated statements of comprehensive income. We recorded (losses) gains on investments held in the trust of less than $(1) and $2 for the three months ended September 30, 2021 and 2020, respectively, and $4 and $1 for the nine months ended September 30, 2021 and 2020, respectively.

(Dollars and shares in millions, except per share amounts)
Cash interest payments. Cash interest payments include interest due on outstanding debt and capital lease payments through maturity.
Satellite and transmission. We have entered into agreements with a third party to design and build two new satellites, SXM-9 and SXM-10. We also have entered into agreements with third parties to operate and maintain satellite telemetry, tracking and control facilities and certain components of our terrestrial repeater networks.
Programming and content. We have entered into various programming and content agreements. Under the terms of these agreements, our obligations include fixed payments, advertising commitments and revenue sharing arrangements. In certain of these agreements, the future revenue sharing costs are dependent upon many factors and are difficult to estimate; therefore, they are not included in our minimum contractual cash commitments.
Sales and marketing. We have entered into various marketing, sponsorship and distribution agreements to promote our brands and are obligated to make payments to sponsors, retailers, automakers, radio manufacturers and other third parties under these agreements. Certain programming and content agreements also require us to purchase advertising on properties owned or controlled by the licensors.
Satellite incentive payments. Boeing Satellite Systems International, Inc., the manufacturer of certain of our in-orbit satellites, may be entitled to future in-orbit performance payments upon XM-4 meeting its fifteen-year design life, which we expect to occur. Boeing may also be entitled to up to $10 of additional incentive payments if our XM-4 satellite continues to operate above baseline specifications during the five years beyond the satellite’s fifteen-year design life.
Maxar Technologies (formerly Space Systems/Loral), the manufacturer of certain of our in-orbit satellites, may be entitled to future in-orbit performance payments upon XM-5, SIRIUS FM-5, SIRIUS FM-6, and SXM-8 meeting their fifteen-year design life, which we expect to occur.
Operating lease obligations. We have entered into both cancelable and non-cancelable operating leases for office space, terrestrial repeaters, data centers and equipment. 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 have options to renew.
Royalties, Minimum Guarantees and Other. We have entered into music royalty arrangements that include fixed payments. Certain of our content agreements also contain minimum guarantees. During the nine months ended September 30, 2021, we prepaid $5 in content costs related to minimum guarantees. As of September 30, 2021, we had future fixed minimum guarantee commitments of $576, of which $172 will be paid in 2021 and the remainder will be paid thereafter. On a quarterly basis, we record the greater of the cumulative actual content costs incurred or the cumulative minimum guarantee based on forecasted usage for the minimum guarantee period. The minimum guarantee period is the period of time that the minimum guarantee relates to, as specified in each agreement, which may be annual or a longer period. The cumulative minimum guarantee, based on forecasted usage, considers factors such as listening hours, revenue, subscribers and other terms of each agreement that impact our expected attainment or recoupment of the minimum guarantees based on the relative attribution method.
Several of our content agreements also include provisions related to the royalty payments and structures of those agreements relative to other content licensing arrangements, which, if triggered, cause our payments under those agreements to escalate. In addition, record labels, publishers and performing rights organizations (“PROs”) with whom we have entered into direct license agreements have the right to audit our content payments, and such audits often result in disputes over whether we have paid the proper content costs.
We have also entered into various agreements with third parties for general operating purposes. The cost of our common stock acquired in our capital return program but not paid for as of September 30, 2021 was also included in this category.
In addition to the minimum contractual cash commitments described above, we have entered into other variable cost arrangements. These future costs are dependent upon many factors 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 also have a surety bond of approximately $45 primarily used as security against non-performance

in the normal course of business. We do not have any other significant off-balance sheet financing 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 or party to various claims and lawsuits, including those discussed below.
We record a liability when we believe that it is both probable that a liability will be incurred, and the amount of loss can be reasonably estimated. We evaluate developments in legal matters that could affect the amount of liability that has been previously accrued and make adjustments as appropriate. Significant judgment is required to determine both probability and the estimated amount of a loss or potential loss. We may be unable to reasonably estimate the reasonably possible loss or range of loss for a particular legal contingency for various reasons, including, among others, because: (i) the damages sought are indeterminate; (ii) the proceedings are in the relative early stages; (iii) there is uncertainty as to the outcome of pending proceedings (including motions and appeals); (iv) there is uncertainty as to the likelihood of settlement and the outcome of any negotiations with respect thereto; (v) there remain significant factual issues to be determined or resolved; (vi) the relevant law is unsettled; or (vii) the proceedings involve novel or untested legal theories. In such instances, there may be considerable uncertainty regarding the ultimate resolution of such matters, including the likelihood or magnitude of a possible eventual loss, if any.
Pre-1972 Sound Recording Litigation. On October 2, 2014, Flo & Eddie Inc. filed a class action suit against Pandora in the federal district court for the Central District of California. The complaint alleges a violation of California Civil Code Section 980, unfair competition, misappropriation and conversion in connection with the public performance of sound recordings recorded prior to February 15, 1972 (which we refer to as, “pre-1972 recordings”). On December 19, 2014, Pandora filed a motion to strike the complaint pursuant to California’s Anti-Strategic Lawsuit Against Public Participation (“Anti-SLAPP”) statute, which following denial of Pandora’s motion was appealed to the Ninth Circuit Court of Appeals. In March 2017, the Ninth Circuit requested certification to the California Supreme Court on the substantive legal questions. The California Supreme Court accepted certification. In May 2019, the California Supreme Court issued an order dismissing consideration of the certified questions on the basis that, following the enactment of the Orrin G. Hatch-Bob Goodlatte Music Modernization Act, Pub. L. No. 115-264, 132 Stat. 3676 (2018) (the “MMA”), resolution of the questions posed by the Ninth Circuit Court of Appeals was no longer “necessary to . . . settle an important question of law.”
The MMA grants a potential federal preemption defense to the claims asserted in the aforementioned lawsuits. In July 2019, Pandora took steps to avail itself of this preemption defense, including making the required payments under the MMA for certain of its uses of pre-1972 recordings. Based on the federal preemption contained in the MMA (along with other considerations), Pandora asked the Ninth Circuit to order the dismissal of the Flo & Eddie, Inc. v. Pandora Media, Inc. case. On October 17, 2019, the Ninth Circuit Court of Appeals issued a memorandum disposition concluding that the question of whether the MMA preempts Flo and Eddie's claims challenging Pandora's performance of pre-1972 recordings “depends on various unanswered factual questions” and remanded the case to the District Court for further proceedings.
In October 2020, the District Court denied Pandora’s renewed motion to dismiss the case under California’s anti-SLAPP statute, finding the case no longer qualified for anti-SLAPP due to intervening changes in the law, and denied Pandora’s renewed attempt to end the case. Alternatively, the District Court ruled that the preemption defense likely did not apply to Flo & Eddie’s claims, in part because the District Court believed that the MMA did not apply retroactively. Pandora promptly appealed the District Court’s decision to the Ninth Circuit, and moved to stay appellate briefing pending the appeal of a related case against Sirius XM. On January 13, 2021, the Ninth Circuit issued an order granting the stay of appellate proceedings pending the resolution of a related case against Sirius XM.
On August 23, 2021, the United States Court of Appeals for the Ninth Circuit issued an Opinion in a related case, Flo & Eddie Inc. v. Sirius XM Radio Inc. The related case also concerned a class action suit brought by Flo & Eddie Inc. regarding the public performance of pre-1972 recordings under California law. Relying on California’s copyright statute, Flo & Eddie argued that California law gave it the “exclusive ownership” of its pre-1972 songs, including the right of public performance. The Ninth Circuit reversed the District Court’s grant of partial summary judgment to Flo & Eddie Inc. The Ninth Circuit held that the District Court in this related case erred in concluding that “exclusive ownership” under California’s copyright statute

included the right of public performance. The Ninth Circuit remanded the case for entry of judgment consistent with the terms of the parties’ contingent settlement agreement, and on October 6, 2021, the parties to the related case stipulated to its dismissal with prejudice.
Following issuance of the Flo & Eddie Inc. v. Sirius XM Radio Inc. opinion, on September 3, 2021, the Ninth Circuit lifted the stay of appellate proceedings in Flo & Eddie, Inc. v. Pandora Media, LLC. The Flo & Eddie Inc. v. Sirius XM Radio Inc. decision is precedential in the Ninth Circuit, and therefore we believe substantially narrows the claims that Flo & Eddie may continue to assert against Pandora. We believe we have substantial defenses to the remaining claims asserted in this action, and we intend to defend this action vigorously.
Other Matters. In the ordinary course of business, we are a defendant in various other 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 other matters, in our opinion, is likely to have a material adverse effect on our business, financial condition or results of operations.
(17)Income Taxes
We file a consolidated federal income tax return for all of our wholly owned subsidiaries. For the three months ended September 30, 2021 and 2020, income tax expense was $90 and $72, respectively, and $157 and $226 for the nine months ended September 30, 2021 and 2020, respectively.
Our effective tax rate for the three months ended September 30, 2021 and 2020 was 20.8% and 20.9%, respectively. Our effective tax rate for the nine months ended September 30, 2021 and 2020 was 13.6% and 21.9%, respectively. The effective tax rate for the three months ended September 30, 2021 was primarily impacted by the recognition of excess tax benefits related to share-based compensation. The effective tax rate for the nine months ended September 30, 2021 was primarily impacted by a $95 benefit associated with a state tax audit settlement and the recognition of excess tax benefits related to share-based compensation. The effective tax rates for the three and nine months ended September 30, 2020 were primarily impacted by federal and state tax credits and the recognition of excess tax benefits related to share-based compensation. We estimate our effective tax rate for the year ending December 31, 2021 will be approximately 16%.
As of September 30, 2021 and December 31, 2020, we had a valuation allowance related to deferred tax assets of $76 and $54, respectively, that were not likely to be realized due to the timing of certain federal and state net operating loss limitations.
We are participating in the Compliance Assurance Process of the U.S. Internal Revenue Service (“IRS”) for 2021 which is expected to conclude during 2022. This program allows us to work with the IRS to identify and resolve potential U.S. Federal tax issues before the filing of tax returns. We are continuously audited by various taxing jurisdictions. There are no material assessments which we believe are probable at this time.
On February 1, 2021, Holdings entered into a tax sharing agreement with Liberty Media governing the allocation of consolidated U.S. income tax liabilities and setting forth agreements with respect to other tax matters.
Under the Internal Revenue Code, two corporations may form a consolidated tax group, and file a consolidated federal income tax return, if one corporation owns stock representing at least 80% of the voting power and value of the outstanding capital stock of the other corporation. As of September 30, 2021, Liberty Media beneficially owned, directly and indirectly, approximately 79% of the outstanding shares of our common stock. We expect that Liberty Media could beneficially own, directly and indirectly, over 80% of the outstanding shares of our common stock at some time in 2021, and Holdings and Liberty Media would then become members of the same consolidated tax group. Should that happen, the tax sharing agreement would govern certain matters related to the resulting consolidated federal income tax returns, as well as state and local returns filed on a consolidated or combined basis.
The tax sharing agreement contains provisions that Holdings believes are customary for tax sharing agreements between members of a consolidated group. The tax sharing agreement and our inclusion in Liberty Media’s consolidated tax group is not expected to have any material adverse effect on us.

(18)Segments and Geographic Information
In accordance with FASB ASC Topic 280, Segment Reporting, we disaggregate our operations into two reportable segments: Sirius XM and Pandora. The financial results of these segments are utilized by the chief operating decision maker, who is our Chief Executive Officer, for evaluating segment performance and allocating resources. We report our segment information based on the "management" approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of our reportable segments. For additional information on our segments refer to Note 1.
Segment results include the revenues and cost of services which are directly attributable to each segment. There are no indirect revenues or costs incurred that are allocated to the segments. There are planned intersegment advertising campaigns which will be eliminated. We had less than $1 of intersegment advertising revenue during each of the three and nine months ended September 30, 2021 and 2020.
Segment revenue and gross profit were as follows during the period presented:

All amounts referenced in this Item 2 are in millions, except subscriber amounts are in thousands and per subscriber and per installation amounts are in ones, unless otherwise stated.
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q and with our Annual Report on Form 10-K for the year ended December 31, 2020.
This Quarterly Report on Form 10-Q presents information for Sirius XM Holdings Inc. (“Holdings”). The terms “Holdings,” “we,” “us,” “our,” and “our company” as used herein, and unless otherwise stated or indicated by context, refer to Sirius XM Holdings Inc. and its subsidiaries. "Sirius XM" refers to our wholly owned subsidiary Sirius XM Radio Inc. and its subsidiaries. "Pandora" refers to Sirius XM's wholly owned subsidiary Pandora Media, LLC and its subsidiaries. Holdings has no operations independent of Sirius XM and Pandora.
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, including the risk factor described under “Risk Factors” in Part I, Item 1A of this Quarterly Report on Form 10-Q, 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, 2020 and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” herein and in Part II, Item 7, of our Annual Report on Form 10-K for the year ended December 31, 2020.
Among the significant factors that could cause our actual results to differ materially from those expressed in the forward-looking statements are:
•We face substantial competition and that competition is likely to increase over time
•Our business depends in part upon the auto industry; vehicle production and sales are dependent on many factors, including the availability of consumer credit, general economic conditions, consumer confidence, fuel costs and component supply shortages
•If our efforts to attract and retain subscribers and listeners, or convert listeners into subscribers, are not successful, our business will be adversely affected
•We engage in extensive marketing efforts and the continued effectiveness of those efforts is an important part of our business
•We rely on third parties for the operation of our business, and the failure of third parties to perform could adversely affect our business
•We may not realize the benefits of acquisitions or other strategic investments and initiatives
•A substantial number of our Sirius XM service subscribers periodically cancel their subscriptions and we cannot predict how successful we will be at retaining customers
•Our ability to profitably attract and retain subscribers to our Sirius XM service as our marketing efforts reach more price-sensitive consumers is uncertain
•The impact of COVID-19, including its variant strains, on our business
•Failure of our satellites would significantly damage our business
•Our Sirius XM service may experience harmful interference from wireless operations
•Our Pandora ad-supported business has suffered a substantial and consistent loss of monthly active users, which may adversely affect our Pandora business
•Our failure to convince advertisers of the benefits of our Pandora ad-supported service could harm our business
•If we are unable to maintain revenue growth from our advertising products, particularly in mobile advertising, our results of operations will be adversely affected
•Changes to mobile operating systems and browsers may hinder our ability to sell advertising and market our services
•If we fail to accurately predict and play music, comedy or other content that our Pandora listeners enjoy, we may fail to retain existing and attract new listeners
•Privacy and data security laws and regulations may hinder our ability to market our services, sell advertising and impose legal liabilities
•Consumer protection laws and our failure to comply with them could damage our business

•Failure to comply with FCC requirements could damage our business
•If we fail to protect the security of personal information about our customers, we could be subject to costly government enforcement actions and private litigation and our reputation could suffer
•Interruption or failure of our information technology and communications systems could impair the delivery of our service and harm our business
•The market for music rights is changing and is subject to significant uncertainties
•Our Pandora services depend upon maintaining complex licenses with copyright owners, and these licenses contain onerous terms
•The rates we must pay for “mechanical rights” to use musical works on our Pandora service have increased substantially and these rates may adversely affect our business
•Our use of pre-1972 sound recordings on our Pandora service could result in additional costs
•Failure to protect our intellectual property or actions by third parties to enforce their intellectual property rights could substantially harm our business and operating results
•Some of our services and technologies may use “open source” software, which may restrict how we use or distribute our services or require that we release the source code subject to those licenses
•Rapid technological and industry changes and new entrants could adversely impact our services
•We have a significant amount of indebtedness, and our debt contains certain covenants that restrict our operations
•We are a “controlled company” within the meaning of the NASDAQ listing rules and, as a result, qualify for, and rely on, exemptions from certain corporate governance requirements
•While we currently pay a quarterly cash dividend to holders of our common stock, we may change our dividend policy at any time
•Our principal stockholder has significant influence, including over actions requiring stockholder approval, and its interests may differ from the interests of other holders of our common stock
•If we are unable to attract and retain qualified personnel, our business could be harmed
•Our facilities could be damaged by natural catastrophes or terrorist activities
•The unfavorable outcome of pending or future litigation could have an adverse impact on our operations and financial condition
•We may be exposed to liabilities that other entertainment service providers would not customarily be subject to
•Our business and prospects depend on the strength of our brands
•We face supply chain risks as a result of the global semiconductor supply shortage.
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, except as required by law. 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 operate two complementary audio entertainment businesses - our Sirius XM business and our Pandora business.
Sirius XM
Our Sirius XM business features music, sports, entertainment, comedy, talk, news, traffic and weather channels and other content, as well as podcasts and infotainment services, in the United States on a subscription fee basis. Sirius XM's bundles include live, curated and certain exclusive and on demand programming. The Sirius XM service is distributed through our two proprietary satellite radio systems and streamed via applications for mobile devices, home devices and other consumer electronic equipment. Satellite radios are primarily distributed through automakers, retailers and our website. Our Sirius XM service is also available through our user interface, which we call “360L,” that combines our satellite and streaming services into a single, cohesive in-vehicle entertainment experience.
The primary source of revenue from our Sirius XM business is subscription fees, with most of our customers subscribing to monthly, quarterly, semi-annual or annual plans. We also derive revenue from advertising on select non-music channels, which is sold under the SXM Media brand, direct sales of our satellite radios and accessories, and other ancillary services. As of September 30, 2021, our Sirius XM business had approximately 34.3 million subscribers.

Table of Contents
In addition to our audio entertainment businesses, we provide connected vehicle services to several automakers. These services are designed to enhance the safety, security and driving experience of consumers. We also offer a suite of data services that includes graphical weather, fuel prices, sports schedules and scores and movie listings, a traffic information service that includes information as to road closings, traffic flow and incident data to consumers with compatible in-vehicle navigation systems, and real-time weather services in vehicles, boats and planes.
Sirius XM also holds a 70% equity interest and 33% voting interest in Sirius XM Canada Holdings Inc. (“Sirius XM Canada”). Sirius XM Canada's subscribers are not included in our subscriber count or subscriber-based operating metrics.
Pandora
Our Pandora business operates a music, comedy and podcast streaming discovery platform, offering a personalized experience for each listener wherever and whenever they want to listen, whether through mobile devices, car speakers or connected devices. Pandora enables listeners to create personalized stations and playlists, discover new content, hear artist- and expert-curated playlists, podcasts and select Sirius XM content as well as search and play songs and albums on-demand. Pandora is available as (1) an ad-supported radio service, (2) a radio subscription service (Pandora Plus) and (3) an on-demand subscription service (Pandora Premium). As of September 30, 2021, Pandora had approximately 6.5 million subscribers.
The majority of revenue from our Pandora business is generated from advertising on our Pandora ad-supported radio service which is sold under the SXM Media brand. We also derive subscription revenue from our Pandora Plus and Pandora Premium subscribers.
Our Pandora business also sells advertising on audio platforms and in podcasts unaffiliated with us. Pandora is the exclusive US ad sales representative for SoundCloud. Through this arrangement, Pandora offers advertisers the ability to execute campaigns in the US across the Pandora and SoundCloud listening platforms. We also have arrangements to serve as the ad sales representative for certain podcasts. In addition, through AdsWizz, Pandora provides a comprehensive digital audio advertising technology platform, which connects audio publishers and advertisers with a variety of ad insertion, campaign trafficking, yield optimization, programmatic buying, marketplace and podcast monetization solutions. As of September 30, 2021, our Pandora business had approximately 52.6 million monthly active users.
In February 2020, Sirius XM completed a $75 investment in SoundCloud. SoundCloud is a next-generation music entertainment company, powered by an ecosystem of artists, listeners, and curators on the pulse of what's new, now and next in culture. SoundCloud’s platform enables its users to upload, promote, share and create audio entertainment. The minority investment complements the existing ad sales relationship between SoundCloud and Pandora.
In June 2020, Sirius XM acquired Simplecast for $28 in cash. Simplecast is a podcast management and analytics platform. Refer to Note 3 to our unaudited consolidated financial statements for more information on this acquisition.
In October 2020, Sirius XM acquired the assets of Stitcher from The E.W. Scripps Company and certain of its subsidiaries (“Scripps”) for total consideration of $302, which included $266 in cash and $36 related to contingent consideration. As of September 30, 2021, we will potentially make up to $30 in additional payments to Scripps related to the contingent consideration based on Stitcher's achievement of certain financial metrics in 2021. During each of the three and nine months ended September 30, 2021, we recognized a $17 benefit related to the change in fair value of the 2021 portion of the contingent consideration. The acquisition of Stitcher, in conjunction with Simplecast, creates a full-service platform for podcast creators, publishers and advertisers. Refer to Note 3 to our unaudited consolidated financial statements for more information on this acquisition.
Liberty Media
As of September 30, 2021, Liberty Media beneficially owned, directly and indirectly, approximately 79% of the outstanding shares of our common stock. As a result, we are a “controlled company” for the purposes of the NASDAQ corporate governance requirements.

Sirius XM Revenue
Sirius XM Subscriber Revenue includes fees charged for self-pay and paid promotional subscriptions, U.S. Music Royalty Fees and other ancillary fees.
For the three months ended September 30, 2021 and 2020, subscriber revenue was $1,532 and $1,462, respectively, an increase of 5%, or $70. For the nine months ended September 30, 2021 and 2020, subscriber revenue was $4,521 and $4,372, respectively, an increase of 3% or $149. The increases were primarily driven by growth in our self-pay subscriber base of 5% driving higher self-pay revenue and U.S. Music Royalty Fees, partially offset by lower revenue generated from automakers offering paid promotional subscriptions.
We expect subscriber revenues to increase based on increases in the average price charged and the sale of additional services to subscribers.
Sirius XM Advertising Revenue includes the sale of advertising on Sirius XM’s non-music channels.
For the three months ended September 30, 2021 and 2020, advertising revenue was $47 and $39, respectively, an increase of 21%, or $8. For the nine months ended September 30, 2021 and 2020, advertising revenue was $135 and $108, respectively, an increase of 25% or $27. The increases were due to higher advertising primarily on news and sports channels as we continue to recover to pre-COVID-19 levels.
We expect our Sirius XM advertising revenue to grow as we continue to offer a broader set of channels.
Sirius XM Equipment Revenue includes revenue and royalties from the sale of satellite radios, components and accessories.
For the three months ended September 30, 2021 and 2020, equipment revenue was $41 and $47, respectively, a decrease of 13%, or $6. For the nine months ended September 30, 2021 and 2020, equipment revenue was $149 and $113, respectively, an increase of 32% or $36. The decrease for the three month period was primarily driven by semiconductor supply shortages, automaker plant closings during the quarter due to COVID-19, and lower sales of components and accessories. The increase for the nine month period was driven by higher royalty revenue from new vehicle production as automakers pushed to get back to pre-COVID-19 manufacturing levels during the first half of 2021 and due to our transition to a new generation of chipsets, partially offset by semiconductor supply shortages in the third quarter of 2021.
We expect equipment revenue to increase as the volume of chipsets sold and revenue per unit so ld increases.
Sirius XM Other Revenue includes service and advisory revenue from Sirius XM Canada, our connected vehicle services, and ancillary revenues.
For the three months ended September 30, 2021 and 2020, other revenue was $40 and $39, respectively, an increase of 3%, or $1. For the nine months ended September 30, 2021 and 2020, other revenue was $113 and $115, respectively, a decrease of 2% or $2. The increase for the three month period was primarily driven by higher revenue generated by our connected vehicle services and Sirius XM Canada, partially offset by lower revenue generated by rental car arrangements. The decrease for the nine month period was primarily driven by lower revenue generated by rental car arrangements.
We expect other revenue to remain relatively flat.

Operating Costs
Subscriber Acquisition Costs are costs associated with our satellite radio service and include hardware subsidies paid to radio manufacturers, distributors and automakers; subsidies paid for chipsets and certain other components used in manufacturing radios; device royalties for certain radios and chipsets; product warranty obligations; and freight. The majority of subscriber acquisition costs are incurred and expensed in advance of acquiring a subscriber.

For the three months ended September 30, 2021 and 2020, subscriber acquisition costs were $71 and $110, respectively, a decrease of 35%, or $39, and decreased as a percentage of total revenue. For the nine months ended September 30, 2021 and 2020, subscriber acquisition costs were $245 and $257, respectively, a decrease of 5%, or $12, and decreased as a percentage of total revenue. The decrease for the three month period was driven by lower OEM installations as a result of factory shutdowns during the three months ended September 30, 2021 as well as the semiconductor supply shortages and lower subsidies from contract improvements with certain automakers. The decrease for the nine month period was driven by lower subsidies from contract improvements with certain automakers as well as lower costs resulting from the semiconductor supply shortages during the three months ended September 30, 2021, partially offset by higher OEM installations following factory shutdowns in the second quarter of 2020 associated with the COVID-19 pandemic.
We expect subscriber acquisition costs to grow as the semiconductor supply shortages abate and production returns to normal levels. We intend to continue to offer subsidies and other incentives to induce OEMs to include our technology in their vehicles.

The increases were primarily due to higher streaming and trial-related direct marketing costs as well as higher personnel-related costs.
We anticipate that sales and marketing expenses will increase as we expand programs to retain our existing subscribers,
win back former subscribers, and attract new subscribers and listeners.

Key Financial and Operating Performance Metrics
In this section, we present certain financial performance measures, some of which are presented as Non-GAAP items, which include free cash flow and adjusted EBITDA. We also present certain operating performance measures. Our adjusted EBITDA excludes the impact of share-based payment expense and certain purchase price accounting adjustments related to the merger of Sirius and XM ("XM Merger") and our February 2019 acquisition of Pandora ("the Pandora Acquisition"). Additionally, when applicable, our adjusted EBITDA metric excludes the effect of significant items that do not relate to the on-going performance of our business. We use these Non-GAAP financial and operating performance measures to manage our business, to set operational goals and as a basis for determining performance-based compensation for our employees. See the accompanying glossary on pages 51 through 54 for more details and for the reconciliation to the most directly comparable GAAP measure (where applicable).
We believe these Non-GAAP financial and operating performance measures provide useful information to investors regarding our financial condition and results of operations. We believe these Non-GAAP financial and operating performance measures may be useful to investors in evaluating our core trends because they provide a more direct view of our underlying costs.

Sirius XM
Subscribers. At September 30, 2021, Sirius XM had approximately 34,265 subscribers, a decrease of 170, from the approximately 34,435 subscribers as of September 30, 2020. The decrease was due to the decrease in paid promotional subscribers generated by automakers driven by a shift to shorter paid trials and unpaid trials, partially offset by the growth in our self-pay subscriber base as a result of vehicle sales growth, lower churn rate, and higher new vehicle penetration rate.
For the three months ended September 30, 2021 and 2020, net subscriber additions were (212) and 186, respectively. For the nine months ended September 30, 2021 and 2020, net subscriber additions were (450) and (473), respectively. Paid promotional subscribers decreased due to a shift to shorter paid or free trials at certain automakers, and to a lesser extent, lower vehicle shipments due to semiconductor supply shortages. Self-pay net additions increased driven by higher new vehicle conversion resulting from vehicle sales growth during the first half of 2021 and automakers shift to shorter trial periods than 2020 which drove higher conversion opportunities.
Traffic Users. We offer services that provide graphic information as to road closings, traffic flow and incident data to consumers with compatible in-vehicle navigation systems. At September 30, 2021, Sirius XM had approximately 8,886 traffic users, a decrease of 544 users, or 6%, from the approximately 9,430 traffic users as of September 30, 2020.
Sirius XM Canada Subscribers. At September 30, 2021, Sirius XM Canada had approximately 2,262 subscribers, a decrease of 350, or 13%, from the approximately 2,612 Sirius XM Canada subscribers as of September 30, 2020.
Average Self-pay Monthly Churn is derived by dividing the monthly average of self-pay deactivations for the period by the average number of self-pay subscribers for the period. (See accompanying glossary on pages 51 through 54 for more details.)
For the three months ended September 30, 2021 and 2020, our average self-pay monthly churn rate was 1.5% and 1.7%, respectively. For the nine months ended September 30, 2021 and 2020, our average self-pay monthly churn rate was 1.6% and 1.7%, respectively. The decrease for the three month period was driven by lower vehicle related churn. The decrease for the nine month period was driven by lower non-pay churn and voluntary churn.
ARPU is derived from total earned Sirius XM subscriber revenue (excluding revenue derived from our connected vehicle services) and net advertising revenue, divided by the number of months in the period, divided by the daily weighted average number of subscribers for the period. (See the accompanying glossary on pages 51 through 54 for more details.)
For the three months ended September 30, 2021 and 2020, subscriber ARPU - Sirius XM was $14.84 and $14.15, respectively. For the nine months ended September 30, 2021 and 2020, subscriber ARPU - Sirius XM was $14.57 and $14.02, respectively. The increases were driven by an increase in certain subscription rates and the U.S. Music Royalty Fee and the decline in paid trials as well as higher advertising revenue as we continue to recover to pre-COVID-19 levels.
SAC, Per Installation, is derived from subscriber acquisition costs and margins from the sale of radios, components and accessories (excluding connected vehicle services), divided by the number of satellite radio installations in new vehicles and shipments of aftermarket radios for the period. (See the accompanying glossary on pages 51 through 54 for more details.)
For the three months ended September 30, 2021 and 2020, SAC, per installation, was $13.66 and $20.98, respectively. For the nine months ended September 30, 2021 and 2020, SAC, per installation, was $13.14 and $20.49, respectively. The decreases were driven by reductions to OEM hardware subsidy rates.
Pandora
Monthly Active Users. At September 30, 2021, Pandora had approximately 52,618 monthly active users, a decrease of 5,965 monthly active users, or 10%, from the 58,583 monthly active users as of September 30, 2020. The decrease in monthly active users was driven by a decline in the number of new users.
Subscribers. At September 30, 2021, Pandora had approximately 6,523 subscribers, an increase of 119, or 2%, from the approximately 6,404 subscribers as of September 30, 2020.
For the three months ended September 30, 2021 and 2020, net subscriber additions were (55) and 102, respectively. For the nine months ended September 30, 2021 and 2020, net subscriber additions were 181 and 190, respectively. The decreases were driven by a decline in trial starts, partially offset by lower churn.

Table of Contents
ARPU is defined as average monthly revenue per paid subscriber on our Pandora subscription services. (See the accompanying glossary on pages 51 through 54 for more details.)
For the three months ended September 30, 2021 and 2020, subscriber ARPU - Pandora was $6.70 and $6.83, respectively. For the nine months ended September 30, 2021 and 2020, subscriber ARPU - Pandora was $6.68 and $6.79, respectively. The decreases in subscriber ARPU were primarily due to a change in the mix of Pandora's premium plans.
Ad supported listener hours are a key indicator of our Pandora business and the engagement of our Pandora listeners. We include ad supported listener hours related to Pandora's non-radio content offerings in the definition of listener hours.
For the three months ended September 30, 2021 and 2020, ad supported listener hours were 2,890 and 3,120, respectively. For the nine months ended September 30, 2021 and 2020, ad supported listener hours were 8,780 and 9,530, respectively. The decreases in ad supported listener hours were primarily driven by the decline in monthly active users, partially offset by higher hours per active user.
RPM is a key indicator of our ability to monetize advertising inventory created by our listener hours on the Pandora services. Ad RPM is calculated by dividing advertising revenue by the number of thousands of listener hours of our Pandora advertising-based service.
For the three months ended September 30, 2021 and 2020, RPM was $109.02 and $84.46, respectively. For the nine months ended September 30, 2021 and 2020, RPM was $98.44 and $68.83, respectively. The increases were the result of higher sell-through and pricing increases in advertising implemented by Pandora.
LPM is tracked for our non-subscription, ad-supported service across all Pandora delivery platforms. The content acquisition costs included in our ad LPM calculations are based on the rates set by our license agreements with record labels, performing rights organizations and music publishers or the applicable rates set by the Copyright Royalty Board if we have not entered into a license agreement with the copyright owner of a particular sound recording.
For the three months ended September 30, 2021 and 2020, LPM was $51.08 and $40.16, respectively. For the nine months ended September 30, 2021 and 2020, LPM was $46.93 and $38.11, respectively. The increases were primarily due to the provisions of certain direct licenses between Pandora and the owners of copyrights in sound recordings which require Pandora, under certain circumstances, to pay royalties on the greater of a percentage of its applicable revenue or a per play per consumer basis as well as higher statutory webcasting royalty rates.
LPU is defined as average monthly licensing costs per paid subscriber on our Pandora subscription services. LPU is a key measure of our ability to manage costs for our subscription services.
For the three months ended September 30, 2021 and 2020, LPU was $4.16 and $4.19, respectively. For the nine months ended September 30, 2021 and 2020, LPU was $4.18 and $4.12, respectively. The decrease for the three month period was driven by lower publisher rates. The increase for the nine month period was due to lower minimum guarantees during the nine months ended September 30, 2020 compared to the nine months ended September 30, 2021.
Total Company
Adjusted EBITDA. A djusted EBITDA is defined as net income before interest expense, income tax expense and depreciation and amortization. Adjusted EBITDA excludes the impact of other expense (income), loss on extinguishment of debt, other non-cash charges, such as certain purchase price accounting adjustments, share-based payment expense, legal settlements and reserves, and impairment, restructuring and acquisition costs (if applicable). (See the accompanying glossary on pages 51 through 54 for a reconciliation to GAAP and for more details.)
For the three months ended September 30, 2021 and 2020, adjusted EBITDA was $719 and $661, respectively, an increase of 9%, or $58. For the nine months ended September 30, 2021 and 2020, adjusted EBITDA was $2,101 and $1,915, respectively, an increase of 10%, or $186. The increases were driven by higher advertising and subscriber revenue as well as lower subscriber acquisition costs, partially offset by higher revenue share and royalties, sales and marketing, programming, and personnel-related costs.
Free Cash Flow includes cash provided by operations, net of additions to property and equipment, and restricted and other investment activity. (See the accompanying glossary on pages 51 through 54 for a reconciliation to GAAP and for more details.)

Table of Contents
For the three months ended September 30, 2021 and 2020, free cash flow was $588 and $361, respectively, an increase of $227, or 63%. For the nine months ended September 30, 2021 and 2020, free cash flow was $1,349 and $1,212, respectively, an increase of $137 or 11%. The increases were primarily driven by satellite insurance recoveries and growth in cash generated by operations, partially offset by higher spending on property and equipment and a decrease in deferred revenue driven by a shift to shorter term self-pay and trial subscriptions as well as a shift to free trials at certain automakers.
Liquidity and Capital Resources
Cash Flows for the nine months ended September 30, 2021 compared with the nine months ended September 30, 2020.
The following table presents a summary of our cash flow activity for the periods set forth below:

| For the Nine Months Ended September 30, |  |  |  | 2021 vs 2020 |  |
| 2021 |  | 2020 |  |  |  | Amount |  |
Net cash provided by operating activities | $ | 1,371 |  |  | $ | 1,450 |  |  |  |  | $ | (79) |  |  |
Net cash used in investing activities | (50) |  |  | (344) |  |  |  |  | 294 |  |  |
Net cash used in financing activities | (1,232) |  |  | (1,182) |  |  |  |  | (50) |  |  |

Cash, cash equivalents and restricted cash at end of period | $ | 172 |  |  | $ | 44 |  |  |  |  | $ | 128 |  |  |

Cash Flows Provided by Operating Activities
Cash flows provided by operating activities decreased by $79 to $1,371 for the nine months ended September 30, 2021 from $1,450 for the nine months ended September 30, 2020.
Our largest source of cash provided by operating activities is cash generated by subscription and subscription-related revenues. We also generate cash from the sale of advertising through our Pandora business, advertising on certain non-music channels on Sirius XM and the sale of satellite radios, components and accessories. Our primary uses of cash from operating activities include revenue share and royalty payments to distributors, programming and content providers, and payments to radio manufacturers, distributors and automakers. In addition, uses of cash from operating activities include payments to vendors to service, maintain and acquire listeners and subscribers, general corporate expenditures, and compensation and related costs.
Cash Flows Used in Investing Activities
Cash flows used in investing activities in the nine months ended September 30, 2021 were primarily due to spending primarily for capitalized software and hardware, and to construct a replacement satellite, partially offset by proceeds collected from satellite insurance policies associated with SXM-7. Cash flows used in investing activities in the nine months ended September 30, 2020 were primarily due to our $75 investment in SoundCloud, the acquisition of Simplecast for $28, spending for capitalized software and hardware, and to construct replacement satellites. We spent $172 and $167 on capitalized software and hardware as well as $39 and $36 to construct replacement satellites during the nine months ended September 30, 2021 and 2020, respectively.
Cash Flows Used in Financing Activities
Cash flows used in financing activities consists of the issuance and repayment of long-term debt, the purchase of common stock under our share repurchase program, the payment of cash dividends and taxes paid in lieu of shares issued for stock-based compensation. Proceeds from long term debt have been used to fund our operations, construct and launch new satellites, invest in other infrastructure improvements and purchase shares of our common stock.
Cash flows used in financing activities in the nine months ended September 30, 2021 were primarily due to the redemptions of Sirius XM's 3.875% Senior Notes due 2022 for $1,019, 4.625% Senior Notes due 2024 for $1,541 and 5.375% Senior Notes due 2026 for $1,034, the purchase and retirement of shares of our common stock under our repurchase program for $1,174, the payment of cash dividends of $180, payment of $88 for taxes in lieu of shares issued for share-based compensation, and the repayment of borrowings under our Credit Facility of $654; partially offset by the issuance of $2,000 in aggregate principal amount of 4.00% Senior Notes due 2028, $1,000 in aggregate principal amount of the 3.125% Senior Notes due 2026, and $1,500 in aggregate principal amount of the 3.875% Senior Notes due 2031. Cash flows used in financing

Table of Contents
activities in the nine months ended September 30, 2020 were primarily due to the redemption of Sirius XM's 4.625% Senior Notes due 2023 in the aggregate amount of $507 and Sirius XM's 5.375% Senior Notes due 2025 in the aggregate amount of $1,039, the purchase and retirement for $870 of shares of our common stock under our repurchase program, the payment of cash dividends of $175 and payment of $81 for taxes in lieu of shares issued for share-based compensation; partially offset by the issuance of $1,481 in aggregate principal amount of Sirius XM's 4.125% Senior Notes due 2030, net of costs.
Future Liquidity and Capital Resource Requirements
Based upon our current business plans, we expect to fund operating expenses, capital expenditures, including the construction of replacement satellites, working capital requirements, interest payments, taxes and scheduled maturities of our debt with existing cash, cash flow from operations and borrowings under our Credit Facility. As of September 30, 2021, no amounts were outstanding under our Credit Facility. As the amount available for future borrowing is reduced by $1 related to letters of credit issued for the benefit of Pandora, $1,749 was available for future borrowing under our Credit Facility. We believe that we have sufficient cash and cash equivalents, as well as debt capacity, to cover our estimated short-term and long-term funding needs, including amounts to construct, launch and insure replacement satellites, as well as fund future stock repurchases, future dividend payments and to pursue strategic opportunities.
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.
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 development and introduction of new features or services; significant new or enhanced distribution arrangements; investments in infrastructure, such as satellites, equipment or radio spectrum; and acquisitions and investments, including acquisitions and investments that are not directly related to our existing business.
We may from time to time purchase our outstanding debt through open market purchases, privately negotiated transactions or otherwise. Purchases or retirement of debt, if any, will depend on prevailing market conditions, liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.
Capital Return Program
As of September 30, 2021, our board of directors had authorized for repurchase an aggregate of $18,000 of our common stock. As of September 30, 2021, our cumulative repurchases since December 2012 under our stock repurchase program totaled 3,504 shares for $15,576, and $2,424 remained available for additional repurchases under our existing stock repurchase program authorization.
Shares of common stock may be purchased from time to time on the open market and in privately negotiated transactions, including in accelerated stock repurchase transactions and transactions with Liberty Media and its affiliates. We intend to fund the additional repurchases through a combination of cash on hand, cash generated by operations and future borrowings. The size and timing of any purchases will be based on a number of factors, including price and business and market conditions.
On October 25, 2021, our board of directors declared a quarterly dividend in the amount of $0.0219615 per share of common stock payable on November 29, 2021 to stockholders of record as of the close of business on November 5, 2021. Our board of directors expects to declare regular quarterly dividends, in an aggregate annual amount of $0.087846 per share of common stock.
Debt Covenants
The indentures governing Sirius XM's senior notes and Pandora's convertible notes and the agreement governing the Sirius XM Credit Facility include restrictive covenants. As of September 30, 2021, we were in compliance with such covenants. For a discussion of our “Debt Covenants,” refer to Note 13 to our unaudited consolidated financial statements in this Quarterly Report on Form 10-Q.

Off-Balance Sheet Arrangements
We do not have any significant off-balance sheet arrangements other than those disclosed in Note 16 to our unaudited consolidated financial statements in 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.
Contractual Cash Commitments
For a discussion of our “Contractual Cash Commitments,” refer to Note 16 to our unaudited consolidated financial statements in this Quarterly Report on Form 10-Q.
Related Party Transactions
For a discussion of “Related Party Transactions,” refer to Note 12 to our unaudited consolidated financial statements in this Quarterly Report on Form 10-Q.
On February 1, 2021, Holdings entered into a tax sharing agreement with Liberty Media governing the allocation of consolidated U.S. income tax liabilities and setting forth agreements with respect to other tax matters. The tax sharing agreement was negotiated and approved by a special committee of Holdings’ board of directors, all of whom are independent of Liberty Media.
Under the Internal Revenue Code, two corporations may form a consolidated tax group, and file a consolidated federal income tax return, if one corporation owns stock representing at least 80% of the voting power and value of the outstanding capital stock of the other corporation. As of September 30, 2021, Liberty Media beneficially owned, directly and indirectly, approximately 79% of the outstanding shares of our common stock. We expect that Liberty Media could beneficially own, directly and indirectly, over 80% of the outstanding shares of our common stock in the fourth quarter of 2021, and Holdings and Liberty Media would then become members of the same consolidated tax group. Should that happen, the tax sharing agreement would govern certain matters related to the resulting consolidated federal income tax returns, as well as state and local returns filed on a consolidated or combined basis.
The tax sharing agreement contains provisions that Holdings believes are customary for tax sharing agreements between members of a consolidated group. The tax sharing agreement and our inclusion in Liberty Media’s consolidated tax group is not expected to have any material adverse effect on us.
Critical Accounting Policies and Estimates
For a discussion of our “Critical Accounting Policies and Estimates,” refer to “Management's Discussion and Analysis of
Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2020.
There have been no material changes to our critical accounting policies and estimates since December 31, 2020.
Glossary
Monthly active users - the number of distinct registered users on the Pandora services, including subscribers, which have consumed content within the trailing 30 days to the end of the final calendar month of the period. The number of monthly active users on the Pandora services may overstate the number of unique individuals who actively use our Pandora service, as one individual may use multiple accounts. To become a registered user on the Pandora services, a person must sign-up using an email address or phone number, or access our service using a device with a unique identifier, which we use to create an account for our service.
Average self-pay monthly churn - the Sirius XM monthly average of self-pay deactivations for the period divided by the average number of self-pay subscribers for the period.
Adjusted EBITDA - EBITDA is defined as net income before interest expense, income tax expense and depreciation and amortization. We adjust EBITDA to exclude the impact of other expense (income) as well as certain other charges discussed below. Adjusted EBITDA is a Non-GAAP financial measure that excludes or adjusts for (if applicable): (i) certain adjustments as a result of the purchase price accounting for the XM Merger and the Pandora Acquisition, (ii) share-based payment expense, (iii) impairment, restructuring and acquisition costs, (iv) legal settlements/reserves and (v) other significant operating expense (income) that do not relate to the on-going performance of our business. 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 capital structure and purchase price accounting.

Table of Contents
We believe investors find this Non-GAAP financial measure useful when analyzing our past operating performance with our current performance and comparing our operating performance to the performance of other communications, entertainment and media companies. We believe investors use adjusted EBITDA to estimate our current enterprise value and to make investment decisions. As a result of large capital investments in our satellite radio system, our results of operations reflect significant charges for depreciation expense. We believe the exclusion of share-based payment expense is useful as it is not directly related to the operational conditions of our business. We also believe the exclusion of the legal settlements and reserves, impairment, restructuring and acquisition related costs, and loss on extinguishment of debt, to the extent they occur during the period, is useful as they are significant expenses not incurred as part of our normal operations for the period.
Adjusted EBITDA has certain limitations in that it does not take into account the impact to our consolidated statements of comprehensive income of certain expenses, including share-based payment expense and certain purchase price accounting for the XM Merger and the Pandora Acquisition. 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 unaudited consolidated statements of comprehensive income. 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:

Free cash flow - is derived from cash flow provided by operating activities plus insurance recoveries on our satellites, net of additions to property and equipment and purchases of other investments. 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 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 exclude from free cash flow certain items that do not relate to the on-going performance of our business, such as cash flows related to acquisitions, strategic and short-term investments, and net loan activity with related parties and other equity investees. 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 operating activities,” is a Non-GAAP financial measure. 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 operating activities” from the unaudited 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 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. Free cash flow is calculated as follows:

Ad supported listener hours - is based on the total bytes served over our Pandora advertising supported platforms for each track that is requested and served from our Pandora servers, as measured by our internal analytics systems, whether or not a listener listens to the entire track. For non-music content such as podcasts, episodes are divided into approximately track-length parts, which are treated as tracks. To the extent that third-party measurements of advertising hours are not calculated using a similar server-based approach, the third-party measurements may differ from our measurements.
RPM - is calculated by dividing advertising revenue, excluding AdsWizz and other off-platform revenue, by the number of thousands of listener hours on our Pandora advertising-based service.
LPM - is calculated by dividing advertising licensing costs by the number of thousands of listener hours on our Pandora advertising-based service.
LPU - is calculated by dividing subscriber licensing costs by the number of paid subscribers on our Pandora subscription services.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS
As of September 30, 2021, we did not hold or issue any free-standing derivatives. We hold investments in money market funds and certificates of deposit. These securities are consistent with the objectives contained within 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. As of September 30, 2021, we also held the following material investment:
•In connection with the recapitalization of Sirius XM Canada, on May 25, 2017, we loaned Sirius XM Canada $131 million. The loan is denominated in Canadian dollars and is subject to changes in foreign currency. It is considered a long-term investment with any unrealized gains or losses reported within Accumulated other comprehensive (loss) income. Such loan has a term of fifteen years, bears interest at a rate of 7.62% per annum and includes customary covenants and events of default, including an event of default relating to Sirius XM Canada’s failure to maintain specified leverage ratios. The carrying value of the loan as of September 30, 2021 was $121.0 million and approximates its fair value as of such date. Had the Canadian to U.S. dollar exchange rate been 10% lower as of September 30, 2021, the value of this loan would have been approximately $12 million lower.
Our debt includes fixed rate instruments and the fair market value of our debt is sensitive to changes in interest rates. Sirius XM’s borrowings under the Credit Facility carry a variable interest rate based on London Inter-bank Offered Rate (“LIBOR”) plus a n applicable rate based on its debt to operating cash flow ratio. LIBOR is the subject of national, international and other regulatory guidance and proposals for reform. On July 27, 2017, the United Kingdom's Financial Conduct Authority (“FCA”), which regulates LIBOR, announced that it intends to phase out LIBOR. On March 5, 2021, the FCA announced that all LIBOR settings will either cease to be provided by any administrator or no longer be representative: (a) immediately after December 31, 2021, in the case of the one week and two month U.S. dollar settings; and (b) immediately after June 30, 2023, in the case of the remaining U.S. dollar settings. The United States Federal Reserve has also advised banks to cease entering into new contracts that use USD LIBOR as a reference rate. The Alternative Reference Rate Committee, a committee convened by
54

Table of Contents
the Federal Reserve that includes major market participants, has identified the Secured Overnight Financing Rate, or SOFR, a new index calculated by short-term repurchase agreements, backed by Treasury securities, as its preferred alternative rate for LIBOR. At this time, it is not possible to predict how markets will respond to SOFR or other alternative reference rates as the transition away from the LIBOR benchmarks is anticipated in coming years. Accordingly, the outcome of these reforms is uncertain and any changes in the methods by which LIBOR is determined or regulatory activity related to LIBOR’s phaseout could cause LIBOR to perform differently than in the past or cease to exist. The consequences of these developments cannot be entirely predicted, but could include an increase in the cost of our borrowings under the Credit Facility. In addition, we may, in the future, hedge against interest rate fluctuations by using hedging instruments such as swaps, caps, options, forwards, futures or other similar products. These instruments may be used to selectively manage risks, but there can be no assurance that we will be fully protected against material interest rate fluctuations.
ITEM 4. CONTROLS AND PROCEDURES
Controls and Procedures
We maintain a set of disclosure controls and procedures designed to ensure that information required to be disclosed in reports that we file or submit under the Exchange Act of 1934, is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosures. The design of any disclosure controls and procedures is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Any controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving the desired control objectives.
As of September 30, 2021, an evaluation was performed under the supervision and with the participation of our management, including our Chief Executive Officer 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 of 1934). 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 September 30, 2021.
Changes in Internal Control Over Financial Reporting
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 of 1934) during the quarter ended September 30, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1. LEGAL PROCEEDINGS
For a discussion of our “Legal Proceedings,” refer to Note 16 to our unaudited consolidated financial statements in this Quarterly Report on Form 10-Q.
ITEM 1A. RISK FACTORS
The following risk factor supplements the Risk Factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the Securities and Exchange Commission on February 2, 2021.
We face supply chain risks as a result of the global semiconductor supply shortage.
The global semiconductor supply shortage is having wide-ranging effects across multiple industries, including direct and indirect effects on our business. We have experienced, and may continue to experience, delays in securing certain application specific integrated circuits (which are commonly referred to as "chipsets") that are essential components of our satellite radios. In addition, automakers are experiencing, and may continue to experience, delays in securing certain chipsets that are essential components of new vehicles for a variety of reasons, including due to closures at semiconductor manufacturing facilities. All of these affected automakers manufacture and sell vehicles that include our satellite radios. For example, some automobile plants in North America and elsewhere have halted or reduced vehicle production due to the shortage of semiconductors used in the production of their vehicles. As a result, the semiconductor supply shortage has had, and may continue to have, an impact on new vehicle deliveries, which in turn may affect our subscriber acquisition efforts.
ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
As of September 30, 2021, our board of directors had approved for repurchase an aggregate of $18.0 billion of our common stock. Our board of directors did not establish an end date for this stock repurchase program. Shares of common stock may be purchased from time to time on the open market, pursuant to pre-set trading plans meeting the requirements of Rule 10b5-1 under the Exchange Act, in privately negotiated transactions, including transactions with Liberty Media and its affiliates, or otherwise. As of September 30, 2021, our cumulative repurchases since December 2012 under our stock repurchase program totaled 3.5 billion shares for $15.6 billion, and $2.4 billion remained available under our existing $18.0 billion stock repurchase program. The size and timing of these purchases will be based on a number of factors, including price and business and market conditions.
The following table provides information about our purchases of equity securities registered pursuant to Section 12 of the Exchange Act, as amended, during the quarter ended September 30, 2021:

Period |  | Total Number of Shares Purchased |  | Average Price Paid Per Share (a) |  | Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs |  | Approximate Dollar Value of Shares that May Yet Be Purchased Under the Plans or Programs (a)
