Explanatory Note
This Quarterly Report on Form 10-Q is for the three and six months ended March 31,June 30, 2021. This Quarterly Report on Form 10-Q modifies and supersedes documents filed before it. The U.S. Securities and Exchange Commission (“SEC”) allows us to “incorporate by reference” information that we file with it, which means that we can disclose important information to you by referring you directly to those documents. Information incorporated by reference is considered to be part of this Quarterly Report on Form 10-Q. In addition, information that we file with the SEC in the future will automatically update and supersede information contained in this Quarterly Report on Form 10-Q.
Unless indicated otherwise, throughout this Quarterly Report on Form 10-Q, we refer to Comcast and its consolidated subsidiaries, as “Comcast,” “we,” “us” and “our;” Comcast Cable Communications, LLC and its consolidated subsidiaries as “Comcast Cable;” Comcast Holdings Corporation as “Comcast Holdings;” NBCUniversal Media, LLC and its consolidated subsidiaries as “NBCUniversal;” and Sky Limited and its consolidated subsidiaries as “Sky.”
Numerical information in this report is presented on a rounded basis using actual amounts. Minor differences in totals and percentage calculations may exist due to rounding.
CAUTION CONCERNING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q includes statements that may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements are not historical facts or statements of current conditions, but instead represent only our beliefs regarding future events, many of which, by their nature, are inherently uncertain and outside of our control. These may include estimates, projections and statements relating to our business plans, objectives and expected operating results, which are based on current expectations and assumptions that are subject to risks and uncertainties that may cause actual results to differ materially. These forward-looking statements are generally identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “potential,” “strategy,” “future,” “opportunity,” “commit,” “plan,” “may,” “should,” “could,” “will,” “would,” “will be,” “will continue,” “will likely result” and similar expressions.
In evaluating forward-looking statements, you should consider various factors, including the risks and uncertainties we describe in the “Risk Factors” sections of our Forms 10-K and 10-Q and other reports we file with the SEC. Additionally, we operate in a highly competitive, consumer-driven and rapidly changing environment. This environment is affected by government regulation; economic, strategic, political and social conditions; consumer response to new and existing products and services; technological developments; and the ability to develop and protect intellectual property rights. Any of these factors could cause



our actual results to differ materially from our forward-looking statements, which could adversely affect our businesses, results of operations or financial condition. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date they are made. We undertake no obligation to update or revise publicly any forward-looking statements, whether because of new information, future events or otherwise.



Our businesses may be affected by, among other things, the following:
the COVID-19 pandemic has had, and will likely continue to have, a material adverse effect on our businesses and results of operations
our businesses operate in highly competitive and dynamic industries, and our businesses and results of operations could be adversely affected if we do not compete effectively
changes in consumer behavior driven by online video distribution platforms for viewing content continue to adversely affect our businesses and challenge existing business models
a decline in advertisers’ expenditures or changes in advertising markets could negatively impact our businesses
programming expenses for our video services are increasing, which could adversely affect Cable Communications’ video businesses
NBCUniversal’s and Sky’s success depends on consumer acceptance of their content, and their businesses may be adversely affected if their content fails to achieve sufficient consumer acceptance or the costs to create or acquire content increase
the loss of programming distribution and licensing agreements, or the renewal of these agreements on less favorable terms, could adversely affect our businesses
less favorable European telecommunications access regulations, the loss of Sky’s transmission access agreements with satellite or telecommunications providers or the renewal of these agreements on less favorable terms could adversely affect Sky’s businesses
our businesses depend on using and protecting certain intellectual property rights and on not infringing the intellectual property rights of others
we may be unable to obtain necessary hardware, software and operational support
weak economic conditions may have a negative impact on our businesses
acquisitions and other strategic initiatives present many risks, and we may not realize the financial and strategic goals that we had contemplated
we face risks relating to doing business internationally that could adversely affect our businesses
our businesses depend on keeping pace with technological developments
we rely on network and information systems and other technologies, as well as key properties, and a disruption, cyber attack, failure or destruction of such networks, systems, technologies or properties may disrupt our businesses
the loss of key management personnel or popular on-air and creative talent could have an adverse effect on our businesses
we are subject to regulation by federal, state, local and foreign authorities, which impose additional costs and restrictions on our businesses
unfavorable litigation or governmental investigation results could require us to pay significant amounts or lead to onerous operating procedures
labor disputes, whether involving employees or sports organizations, may disrupt our operations and adversely affect our businesses
our Class B common stock has substantial voting rights and separate approval rights over several potentially material transactions, and our Chairman and CEO has considerable influence over our company through his beneficial ownership of our Class B common stock

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
Note 1: Condensed Consolidated Financial Statements
Basis of Presentation
We have prepared these unaudited condensed consolidated financial statements based on SEC rules that permit reduced disclosure for interim periods. These financial statements include all adjustments that are necessary for a fair presentation of our consolidated results of operations, cash flows and financial condition for the periods shown, including normal, recurring accruals and other items. The consolidated results of operations for the interim periods presented are not necessarily indicative of results for the full year.
The year-end condensed consolidated balance sheet was derived from audited financial statements but does not include all disclosures required by generally accepted accounting principles in the United States (“GAAP”). For a more complete discussion of our accounting policies and certain other information, refer to our consolidated financial statements included in our 2020 Annual Report on Form 10-K and the notes within this Form 10-Q.
Reclassifications
Reclassifications have been made to our notes to condensed consolidated financial statements for the prior year period to conform to classifications used in 2021. See Note 2 for a discussion of the changes in our presentation of segment operating results.
Note 2: Segment Information
In the first quarter of 2021, we changed our presentation of segment operating results. We now present our operations in 5 reportable business segments: (1) Comcast Cable in 1 reportable business segment, referred to as Cable Communications; (2) NBCUniversal in 3 reportable business segments: Media, Studios and Theme Parks (collectively, the “NBCUniversal segments”); and (3) Sky in 1 reportable business segment. The changes reflect a reorganized operating structure in NBCUniversal’s television and streaming businesses and primarily include: (i) the combination of NBCUniversal’s television networks (previously reported in Cable Networks and Broadcast Television) with the operations of Peacock (previously reported in Corporate and Other) in the Media segment, and (ii) the presentation of NBCUniversal’s television studio production operations (previously reported in Cable Networks and Broadcast Television) with the studio operations of Filmed Entertainment in the Studios segment. Prior periods have been adjusted to reflect this presentation.
Cable Communications is a leading provider of broadband, video, voice, wireless, and security and automation services to residential customers under the Xfinity brand; we also provide these and other services to business customers and sell advertising. Revenue is generated primarily from residential and business customers that subscribe to our services, which are marketed individually and as bundled services, and from the sale of advertising.
Media consists primarily of NBCUniversal’s television and streaming platforms, including national, regional and international cable networks; the NBC and Telemundo broadcast networks; NBC and Telemundo owned local broadcast television stations; Peacock, our direct-to-consumer streaming service; and various digital properties. Revenue is generated primarily from the sale of advertising on our television networks, Peacock and digital properties; and the fees received from the distribution of our television network programming to traditional and virtual multichannel video providers and from NBC-affiliated and Telemundo-affiliated local broadcast television stations. Media also generates other revenue from various digital properties.
Studios consists primarily of NBCUniversal’s film and television studio production and distribution operations. Revenue is generated primarily from the licensing of our owned film and television content to broadcast, cable and premium networks, and to direct-to-consumer streaming service providers, as well as through video on demand and pay-per-view services provided by multichannel video providers and over-the-top service providers; from the worldwide distribution of our produced and acquired films for exhibition in movie theaters; and from the sale of owned content on DVDs, Blu-ray discs and through digital distribution services.
Theme Parks consists primarily of our Universal theme parks in Orlando, Florida; Hollywood, California; and Osaka, Japan. In addition, we are developing a theme park in Beijing, China along with a consortium of Chinese state-owned companies, and an additional theme park in Orlando, Florida. Revenue is generated primarily from guest spending at our Universal theme parks.
Sky is one of Europe’s leading entertainment companies, which primarily includes a direct-to-consumer business, providing video, broadband, voice and wireless phone services, and a content business, operating entertainment networks, the Sky News broadcast network and Sky Sports networks. Revenue is generated primarily from residential and business customers that

subscribe to our services; from the distribution of Sky’s owned television networks on third-party platforms and the licensing of owned and acquired programming to third-party video providers; and from the sale of advertising.
Our other business interests consist primarily of the operations of Comcast Spectacor, which owns the Philadelphia Flyers and the Wells Fargo Center arena in Philadelphia, Pennsylvania, and other business initiatives.
We use Adjusted EBITDA to evaluate the profitability of our operating segments and the components of net income attributable to Comcast Corporation excluded from Adjusted EBITDA are not separately evaluated. Our financial data by businessreportable segment is presented in the tables below.

(a)Included in Eliminations are transactions that our segments enter into with one another. Our segments generally report transactions with one another as if they were stand-alone businesses in accordance with GAAP, and these transactions are eliminated in consolidation. When multiple segments enter into transactions to provide products and services to third parties, revenue is generally allocated to our segments based on relative value. The most significant transactions between our segments include distribution revenue at Media for fees received from Cable Communications for the sale of cable network programming and under retransmission consent agreements; content licensing revenue at Studios for licenses of owned content to Media and Sky; and advertising revenue at Media and Cable Communications. Revenue for licenses of content from Studios to Media and Sky is generally recognized at a point in time, consistent with the recognition of transactions with third parties, when the content is delivered and made available for use. The costs of these licenses at Media and Sky are recognized as the content is used over the license period. The difference in timing of recognition between segments results in an Adjusted EBITDA impact in eliminations, as the profits (losses) on these transactions are deferred in our consolidated results and recognized as the content is used over the license period. Under the previous segment structure, revenue for licenses of content between our previous NBCUniversal segments was recognized over time to correspond with the amortization of the costs of licensed content over the license period.
A summary of revenue for each of our segments resulting from transactions with other segments and eliminated in consolidation is presented in the table below.

From time to time we may report the impact of certain events, gains, losses or other charges related to our operating segments (such as certain costs incurred in response to COVID-19, including severance charges), within Corporate and Other. Our reconciliation of the aggregate amount of Adjusted EBITDA for our reportable segments to consolidated income before income taxes is presented in the table below.

Note 5: Long-Term Debt
As of March 31,June 30, 2021, our debt had a carrying value of $103.7$98.6 billion and an estimated fair value of $117.8$114.7 billion. As of December 31, 2020, our debt had a carrying value of $103.8 billion and an estimated fair value of $125.6 billion. The estimated fair value of our publicly traded debt was primarily based on Level 1 inputs that use quoted market value for the debt. The estimated fair value of debt for which there are no quoted market prices was based on Level 2 inputs that use interest rates available to us for debt with similar terms and remaining maturities.
In March 2021, we entered into a new $11 billion revolving credit facility due March 30, 2026 with a syndicate of banks that may be used for general corporate purposes. We may increase the commitments under the revolving credit facility up to a total of $14 billion, as well as extend the expiration date to no later than March 30, 2028, subject to approval of the lenders. The interest rate on the revolving credit facility consists of a base rate plus a borrowing margin that is determined based on Comcast’s credit rating. As of March 31,June 30, 2021, the borrowing margin for borrowings based on the London Interbank Offered Rate was 1.00%. Our revolving credit facility requires that we maintain certain financial ratios based on debt and EBITDA, as defined in the revolving credit facility. We were in compliance with all financial covenants for all periods presented. The new

ITEM 2: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion is provided as a supplement to, and should be read in conjunction with, the condensed consolidated financial statements and related notes included in this Quarterly Report on Form 10-Q and our 2020 Annual Report on Form 10-K.
Overview
We are a global media and technology company with three primary businesses: Comcast Cable, NBCUniversal, and Sky. We present our operations for (1) Comcast Cable in one reportable business segment, referred to as Cable Communications; (2) NBCUniversal in three reportable business segments: Media, Studios and Theme Parks (collectively, the “NBCUniversal segments”); and (3) Sky in one reportable business segment. Refer to Note 2 for information on our reportable segments, including a description of the segment change implemented in the first quarter of 2021. All amounts are presented on a consistent basis under the new segment structure.
Impacts of COVID-19
The novel coronavirus disease 2019 (“COVID-19”) and measures taken to prevent its spread across the globe have impacted our businesses in a number of ways. COVID-19 has had and we expect will continue to have, material negative impacts on NBCUniversal and Sky results of operations primarily due to the temporary restrictions and closures at our theme parks and the impacts of professional sports, respectively. We expect the impactseffects of the COVID-19 pandemic will continue to have a material adverseadversely impact on our consolidated results of operations over the near to medium term, although the extent of such impact will depend on restrictive governmental measures, further deterioration of theU.S. and global economy, widespreadeconomic conditions, expanded availability and acceptance of vaccines and consumer behavior in response to COVID-19. The most significant effects of COVID-19 began in the second halflatter part of the first quarter of 2020.2020, affecting the comparability of periods included in this report. The following summary provides a discussion of current and potential future effects of the pandemic with direct impacts to our businesses.
Cable Communications
Beginning in March 2020, and continuing through June 2021, new qualifying customers for Internet Essentials, our low-income internet adoption program, receive 60 days of free broadband services. Our customer metrics do not include customers in the free Internet Essentials offer or certain high-risk customers who continued to receive service following nonpayment as a result of COVID-19 programs. The number of customers excluded from our customer metrics has continued to decrease as some of these customers either began paying for service, resulting in customer net additions, or disconnected and no longer receive service, and we expect this to continue in future periods. We alsohave experienced improvement in customer collections; however, we believe there continues to be a risk associated with collections on customer accounts.our outstanding receivables as a result of COVID-19.
NBCUniversal
In the first quarter of 2021, ourOur theme parks in Orlando and JapanHollywood were openoperating without capacity restrictions as of the end of the second quarter of 2021, following periods with limited capacity while our parkrestrictions in Hollywood remained closed. In April 2021, our theme park in Hollywood reopened with limited capacity, but ourplace. Our theme park in Japan haswas temporarily closed.closed for a period in the second quarter of 2021, but was reopened and operating with capacity restrictions as of the end of the quarter. The limited capacity restrictions and closuretemporary closures of our theme parks had a significant impact on our revenue and Adjusted EBITDA for the three and six months ended March 31,June 30, 2021 on a consolidated basis. We expect the results of operations at our theme parks will continue to be negatively impacted and we cannot predict if anyour parks will remain open or be subject to capacity restrictions, or the level of attendance at our reopened parks. We currently expect that Universal Beijing Resort will open during summer 2021 and we have resumed thelater in 2021. The development of the Epic Universe theme park in Orlando resumed in the first quarter of 2021.
Delays to the start of current seasons for certain professional sports leagues, including the 2020-2021 NHL and NBA seasons, resulted in the shift of additional events into the first quarterand second quarters of 2021 compared to a normal year, which impacted the timing of revenue and expense recognition, sincebecause both advertising revenue and costs associated with broadcasting these programs are recognized when events are broadcast. We also expect additional eventsthe timing of sports seasons to generally return to a normal calendar beginning in the secondthird quarter of 2021 compared to the same period in the prior year. We cannot predict the ultimate timing of when, or the extent to which, sporting events will occur in future periods.2021. In addition, the 2020 Tokyo Olympics have beenwere postponed from the third quarter of 2020 to the third quarter of 2021, resulting in a corresponding delay of the associated revenue and costs.
Our studio production operations have resumed, with some at a limitedgenerally returned to full capacity. Additionally, withWith the temporary closure and limited-capacitylimited capacity operation of many movie theaters worldwide, we have delayed or altered the theatrical distribution strategy for certain of our films, both domestically and internationally. Delays in theatrical releases will affect both current and future periods as a result of corresponding delays in subsequent content licensing windows. We expect results of

operations in our Studios segment to continue to be negatively impacted over the near to medium term as a result of COVID-19.

Direct-to-consumer revenue has been negatively impacted, and future periods may be negatively impacted, as a result of lower sports subscription revenue due to the closures and extent of reopening of our commercial customers.customers locations. In addition, delays to the start of the current2020-2021 seasons for certain sports, including European football, resulted in the shift of additional events and the significant costs associated with broadcasting these programs into the first quarter of 2021.

We cannot predict the ultimate timingthird quarter of when, or the extent to which, sporting events will occur in future periods.2021.
In 2020, our businesses implemented separate cost savings initiatives, with the most significant relating to severance at NBCUniversal in connection with the realignment of the operating structure in our television businesses as well as overall reductions in the cost base. The costs of these initiatives were presented in Corporate and Other. Payments related to NBCUniversal employee severance are expected to be completed in 2021 and the related costs savings will be realized in operating costs and expenses primarily beginning in 2021. A portion of these cost savings may be reallocated to investments in content and other strategic initiatives.

Consolidated Income Tax Expense
Income tax expense for the three and six months ended March 31,June 30, 2021 and 2020 reflects an effective income tax rate that differs from the federal statutory rate primarily due to state and foreign income taxes and adjustments associated with uncertain tax positions. The increaseincreases in income tax expense for the three and six months ended March 31,June 30, 2021 compared to the same periodperiods in 2020 waswere primarily due to higher income before income taxes. We also recognized income tax expense of $498 million related to an increase in our net deferred tax liability as a result of the enactment of tax law changes in the United Kingdom in the second quarter of 2021. Refer to Note 9 for further discussion.

Customer metrics are presented based on actual amounts. Minor differences may exist due to rounding. Customer relationships represent the number of residential and business customers that subscribe to at least one of our services. One product, two product, and three or more product customers represent residential customers that subscribe to one, two, or three or more of our services, respectively. For multiple dwelling units (“MDUs”), including buildings located on college campuses, whose residents have the ability to receive additional services, such as additional programming choices or our high-definition video (“HD”) or digital video recorder (“DVR”) services, we count and report customers based on the number of potential billable relationships within each MDU. For MDUs whose residents are not able to receive additional services, the MDU is counted as a single customer. Residential broadband and video customer metrics include certain customers that have prepaid for services. Business customers are generally counted based on the number of locations receiving services within our distribution system, with certain offerings such as Ethernet network services counted as individual customer relationships. Wireless lines represent the number of activated, eligible wireless devices on customers’ accounts. Individual customer relationships may have multiple wireless lines. Customer metrics for 2021 and 2020 do not include customers in the free Internet Essentials offer or certain high-risk customers who continued to receive service following nonpayment (refer to “Impacts of COVID-19” for further discussion). Total residential customer relationships and broadband customers were updated in the first quarter of 2021 due to a conforming change to methodology, resulting in a reduction of approximately 26,000 customers. There was no impact to net additions and information for all periods presented have been recast on a comparable basis.

Average monthly total revenue per customer relationship is impacted by rate adjustments and changes in the types and levels of services received by our residential and business services customers, as well as changes in advertising revenue. While revenue from our residential broadband, video and voice services is also impacted by changes in the allocation of revenue among services sold in a bundle, the allocation does not impact average monthly total revenue per customer relationship.
Each of our services has a different contribution to operating margin and we also use average monthly Adjusted EBITDA per customer relationship to evaluate the profitability of our customer base across our service offerings. We believe these metrics are useful to understand the trends in our business and average monthly Adjusted EBITDA per customer relationship is useful particularly as we continue to focus on growing our higher-margin businesses, including residential broadband and business services.

Media Segment – Revenue
Revenue increased for the three and six months ended March 31,June 30, 2021 compared to the same periodperiods in 2020 due to increases in advertising revenue, distribution revenue and other revenue. Advertising revenue increased primarily due to an increased number of sporting events and higher pricing in the current year periods, reduced spending from advertisers in the prior year periods as a result of COVID-19 and increased advertising revenue at Peacock. These increases were partially offset by a decrease in advertising revenue.continued audience ratings declines at our networks. Distribution revenue increased due to contractual rate increases in the current year periods and credits accrued in the prior year periods at some of our regional sports networks resulting from the reduced number of games played by professional sports leagues due to COVID-19, partially offset by declines in the number of subscribers at our networks. Other revenue increased primarily due to an increase inincreased revenue from our digital properties. Advertising revenue decreased primarily due to continued audience ratings declines at our networks, partially offset by higher prices for advertising units sold, an increase in the number of units sold related to sports and an increase in advertising revenue at Peacock.
We expect the number of subscribers and audience ratings at our networks towill continue to decline as a result of the competitive environment and shifting video consumption patterns. Revenue included $91$122 million and $213 million related to Peacock for the three and six months ended March 31, 2021.June 30, 2021, respectively. Revenue included $6 million related to Peacock for both the three and six months ended June 30, 2020.

Customer metrics are presented based on actual amounts. Minor differences may exist due to rounding. Customer relationships represent the number of residential customers that subscribe to at least one of Sky’s four primary services of video, broadband, voice and wireless phone service. Sky reports commercial customers, including hotels, bars, workplaces and restaurants, generally based on the number of locations receiving our services. In the first quarter of 2021, we implemented conforming changes to our methodology for counting commercial customers in Italy and Germany, which are now counted as described above, consistent with customers in the United Kingdom. Previously these customers were counted based on a residential equivalent unit in Italy and the number of active venues or rooms in Germany. This change resulted in a reduction in Sky’s total customer relationships of 714,000 as of December 31, 2020. The impact of the change in methodology to customer relationship net additions for any period was not material. For comparative purposes, we have updated Sky’s historical total customer relationships and average monthly direct-to-consumer revenue per customer relationship to reflect this adjustment.

Average monthly direct-to-consumer revenue per customer relationship is impacted by rate adjustments and changes in the types and levels of services received by Sky’s customers. Each of Sky’s services has a different contribution to Adjusted EBITDA. We believe average monthly direct-to-consumer revenue per customer relationship is useful in understanding the trends in our business across all of our direct-to-consumer service offerings.

Direct-to-Consumer

Non-GAAP Financial Measures
Consolidated Adjusted EBITDA
Adjusted EBITDA is a non-GAAP financial measure and is the primary basis used to measure the operational strength and performance of our businesses as well as to assist in the evaluation of underlying trends in our businesses. This measure eliminates the significant level of noncash depreciation and amortization expense that results from the capital-intensive nature of certain of our businesses and from intangible assets recognized in business combinations. It is also unaffected by our capital and tax structures, and by our investment activities, including the results of entities that we do not consolidate, as our management excludes these results when evaluating our operating performance. Our management and Board of Directors use this financial measure to evaluate our consolidated operating performance and the operating performance of our operating segments and to allocate resources and capital to our operating segments. It is also a significant performance measure in our annual incentive compensation programs. Additionally, we believe that Adjusted EBITDA is useful to investors because it is one of the bases for comparing our operating performance with that of other companies in our industries, although our measure of Adjusted EBITDA may not be directly comparable to similar measures used by other companies.
2426

Table of ContentsContents
We define Adjusted EBITDA as net income attributable to Comcast Corporation before net income (loss) attributable to noncontrolling interests and redeemable subsidiary preferred stock, income tax expense, investment and other income (loss), net, interest expense, depreciation and amortization expense, and other operating gains and losses (such as impairment charges related to fixed and intangible assets and gains or losses on the sale of long-lived assets), if any. From time to time, we may exclude from Adjusted EBITDA the impact of certain events, gains, losses or other charges (such as significant legal settlements) that affect the period-to-period comparability of our operating performance.
We reconcile consolidated Adjusted EBITDA to net income attributable to Comcast Corporation. This measure should not be considered a substitute for operating income, net income (loss), net income attributable to Comcast Corporation, or net cash provided by operating activities that we have reported in accordance with GAAP.

Certain of our businesses, including Sky, have operations outside the United States that are conducted in local currencies. As a result, the comparability of the financial results reported in U.S. dollars is affected by changes in foreign currency exchange rates. In our Sky segment, we use constant currency and constant currency growth rates to evaluate the underlying performance of the business, and we believe it is helpful for investors to present operating results on a comparable basis period over period to evaluate its underlying performance.
Constant currency and constant currency growth rates are calculated by comparing the comparative period results in the prior year adjusted to reflect the average exchange rates from the current year period rather than the actual exchange rates in effect during the respective prior year periods.

Liquidity and Capital Resources
Our businesses generate significant cash flows from operating activities. We believe that we will be able to continue to meet our current and long-term liquidity and capital requirements, including fixed charges, through our cash flows from operating activities; existing cash, cash equivalents and investments; available borrowings under our existing credit facility; and our ability to obtain future external financing.
We maintain significant availability under our revolving credit facility and commercial paper program to meet our short-term liquidity requirements. As of March 31,June 30, 2021, amounts available under our revolving credit facility, net of amounts outstanding under our commercial paper program and outstanding letters of credit and bank guarantees, totaled $11.0 billion. We entered into a new revolving credit facility in March 2021 (see Note 5).
We are subject to customary covenants and restrictions set forth in agreements related to debt issued at Comcast and certain of our subsidiaries, including the indentures governing our public debt securities and the credit agreements governing the Comcast revolving credit facility. Our credit facility contains a financial covenant pertaining to leverage, which is the ratio of debt to EBITDA, as defined in the credit facility. Compliance with this financial covenant is tested on a quarterly basis under the terms of the credit facility. As of March 31,June 30, 2021, we met this financial covenant by a significant margin and we would expect to remain in compliance with this financial covenant and other covenants related to our debt. The covenants and restrictions in our revolving credit facility do not apply to certain entities, including Sky and our international theme parks.

The new agreement includes exhibition rights for three additional Super Bowls and certain other rights, including streaming rights and additional exclusive games on Peacock.
The increase in income tax payments for the six months ended June 30, 2021 compared to the same period in 2020 was primarily due to the extension of due dates for estimated second quarter 2020 federal income tax payments to the third quarter of 2020.

As of March 31,June 30, 2021, we had no commercial paper outstanding and there were no amounts outstanding under our revolving credit facility.
We have made, and may from time to time in the future make, optional repayments on our debt obligations, which may include repurchases or exchanges of our outstanding public notes and debentures, depending on various factors, such as market conditions. See Notes 5 and 6 for additional information on our financing activities.
Share Repurchases and Dividends
In the second quarter of 2021, we restarted our share repurchase program. Effective May 25, 2021, our Board of Directors increased our share repurchase program authorization to $10 billion, which does not have an expiration date. During the six months ended June 30, 2021, we repurchased a total of 8.8 million shares of our Class A common stock for $500 million. Under the authorization, we expect to repurchase additional shares during the remainder of 2021, which may be in the open market or in private transactions.
In addition, we paid $459 million for the six months ended June 30, 2021 related to employee taxes associated with the administration of our share-based compensation plans.
In January 2021, our Board of Directors approved a 9% increase in our dividend to $1.00 per share on an annualized basis. On April 28, 2021, we paid dividends of $1.2 billion. In JanuaryMay 2021, our Board of Directors approved our firstsecond quarter dividend of $0.25 per share, which was paid in AprilJuly 2021. We expect to continue to pay quarterly dividends, although each dividend is subject to approval by our Board of Directors. On January 27, 2021, we paid dividends of $1.1 billion.
Guarantee Structure
Our debt is primarily issued at Comcast, although we also have debt at certain of our subsidiaries as a result of acquisitions and other issuances. A substantial amount of this debt is subject to guarantees by Comcast and by certain subsidiaries that we have put in place to simplify our capital structure. We believe this guarantee structure provides liquidity benefits to debt investors and helps to simplify credit analysis with respect to relative value considerations of guaranteed subsidiary debt.

Cross-guarantees
Comcast, NBCUniversal and Comcast Cable (the “Guarantors”) fully and unconditionally, jointly and severally, guarantee each other’s debt securities. NBCUniversal and Comcast Cable also guarantee other borrowings of Comcast, including its revolving credit facility. These guarantees rank equally with all other general unsecured and unsubordinated obligations of the respective Guarantors. However, the obligations of the Guarantors under the guarantees are structurally subordinated to the indebtedness and other liabilities of their respective non-guarantor subsidiaries. The obligations of each Guarantor are limited to the maximum amount that would not render such Guarantor’s obligations subject to avoidance under applicable fraudulent conveyance provisions of U.S. and non-U.S. law. Each Guarantor’s obligations will remain in effect until all amounts payable with respect to the guaranteed securities have been paid in full. However, a guarantee by NBCUniversal or Comcast Cable of Comcast’s debt securities, or by NBCUniversal of Comcast Cable’s debt securities, will terminate upon a disposition of such Guarantor entity or all or substantially all of its assets.

Table of Contents
The Guarantors are each holding companies that principally hold investments in, borrow from and lend to non-guarantor subsidiary operating companies; issue and service third-party debt obligations; repurchase shares and pay dividends; and engage in certain corporate and headquarters activities. The Guarantors are generally dependent on non-guarantor subsidiary operating companies to fund these activities.
As of March 31,June 30, 2021 and December 31, 2020, the combined Guarantors have noncurrent notes payable to non-guarantor subsidiaries of $125 billion and $124 billion, respectively, and for both periods have noncurrent notes receivable from non-guarantor subsidiaries of $28 billion and $26 billion.billion, respectively. This financial information is that of the Guarantors presented on a combined basis with intercompany balances between the Guarantors eliminated. The combined financial information excludes financial information of non-guarantor subsidiaries. The underlying net assets of the non-guarantor subsidiaries are significantly in excess of the Guarantor obligations. Excluding investments in non-guarantor subsidiaries, external debt and the noncurrent notes payable and receivable with non-guarantor subsidiaries, the Guarantors do not have material assets, liabilities or results of operations.
One-way Guarantees
Comcast provides full and unconditional guarantees of certain debt issued by Sky and other consolidated subsidiaries not subject to the periodic reporting requirements of the SEC.
Comcast also provides a full and unconditional guarantee of $138 million principal amount of subordinated debt issued by Comcast Holdings. Comcast’s obligations under this guarantee are subordinated and subject, in right of payment, to the prior payment in full of all of Comcast’s senior indebtedness, including debt guaranteed by Comcast on a senior basis; and are
30

Table of Contents
structurally subordinated to the indebtedness and other liabilities of its non-guarantor subsidiaries (for purposes of this Comcast Holdings discussion, Comcast Cable and NBCUniversal are included within the non-guarantor subsidiary group). Comcast’s obligations as guarantor will remain in effect until all amounts payable with respect to the guaranteed debt have been paid in full. However, the guarantee will terminate upon a disposition of Comcast Holdings or all or substantially all of its assets. Comcast Holdings is a consolidated subsidiary holding company that directly or indirectly holds 100% and approximately 37% of our equity interests in Comcast Cable and NBCUniversal, respectively.
As of March 31,June 30, 2021 and December 31, 2020, Comcast and Comcast Holdings, the combined issuer and guarantor of the guaranteed subordinated debt, have noncurrent senior notes payable to non-guarantor subsidiaries of $95$97 billion and $94 billion, respectively, and noncurrent notes receivable from non-guarantor subsidiaries of $24$25 billion and $23 billion, respectively. This financial information is that of Comcast and Comcast Holdings presented on a combined basis with intercompany balances between Comcast and Comcast Holdings eliminated. The combined financial information excludes financial information of non-guarantor subsidiaries of Comcast and Comcast Holdings. The underlying net assets of the non-guarantor subsidiaries of Comcast and Comcast Holdings are significantly in excess of the obligations of Comcast and Comcast Holdings. Excluding investments in non-guarantor subsidiaries, external debt and the noncurrent notes payable and receivable with non-guarantor subsidiaries, Comcast and Comcast Holdings do not have material assets, liabilities or results of operations.
Critical Accounting Judgments and Estimates
The preparation of our condensed consolidated financial statements requires us to make estimates that affect the reported amounts of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and contingent liabilities. We base our judgments on our historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making estimates about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Following the change in presentation of our segment operating results in the first quarter of 2021, we reassessed the reporting units related to goodwill in our NBCUniversal segments and concluded that our reporting units are the same as our reportable segments. See Note 2 for additional information.
For a more complete discussion of the accounting judgments and estimates that we have identified as critical in the preparation of our condensed consolidated financial statements, please refer to our Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2020 Annual Report on Form 10-K.
