Diluted earnings per common share attributable to Comcast Corporation shareholders (“diluted EPS”) considers the impact of potentially dilutive securities using the treasury stock method. Our potentially dilutive securities include potential common shares related to our stock options and our restricted share units (“RSUs”). Diluted EPS excludes the impact of potential common shares related to our stock options in periods in which the combination of the option exercise price and the associated unrecognized compensation expense is greater than the average market price of our common stock. The amount of potential common shares related to our share-based compensation plans that were excluded from diluted EPS because their effect would have been antidilutive was not material for the three and six months ended June 30, 2020 or 2019.

Recent Accounting Pronouncements (Policies)	Jun. 30, 2020
Accounting Policies [Abstract]
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 2019 Annual Report on Form 10-K and the notes within this Form 10-Q.
Film and Television Costs	We capitalize costs for owned film and television content, including direct costs, production overhead, print costs, development costs and interest, as well as acquired libraries. Amortization for content predominantly monetized on an individual basis and accrued costs associated with participations and residual payments are recorded using the individual film forecast computation method, which recognizes the costs in the same ratio as the associated ultimate revenue. Estimates of ultimate revenue and total costs are based on anticipated release patterns, public acceptance and historical results for similar productions. Amortization for content predominantly monetized with other owned or licensed content is recorded based on estimated usage. In determining the method of amortization and estimated life of an acquired film or television library, we generally use the method and the life that most closely follow the undiscounted cash flows over the estimated life of the asset. We do not capitalize costs related to the distribution of a film in movie theaters or the licensing or sale of a film or television production, which primarily include costs associated with marketing and distribution. We may enter into cofinancing arrangements with third parties to jointly finance or distribute certain of our film productions. Cofinancing arrangements can take various forms, but in most cases involve the grant of an economic interest in a film to an investor who owns an undivided copyright interest in the film. The number of investors and the terms of these arrangements can vary, although investors generally assume the full risks and rewards for the portion of the film acquired in these arrangements. We account for the proceeds received from the investor under these arrangements as a reduction of our capitalized film costs and the investor’s interest in the profit or loss of the film is recorded as either a charge or a benefit, respectively, in programming and production costs. The investor’s interest in the profit or loss of a film is recorded each period using the individual film forecast computation method.
Entertainment Entities	We capitalize the costs of programming rights for content that we license but do not own when the license period begins, the content is made available for use and the costs of programming licenses are known. Programming rights are amortized as the associated programs are broadcast.
Film Costs and Entertainment Entities	Owned film and television costs and programming rights are presented as noncurrent assets in film and television costs. We present amortization of film and television costs and accrued costs associated with participation and residual payments in programming and production costs. When an event or a change in circumstance occurs that was known or knowable as of the balance sheet date and that indicates the fair value of either owned film and television content or programming rights is less than the unamortized costs in the balance sheet, we determine the fair value and record an impairment charge to the extent the unamortized costs exceed the fair value. Owned film and television costs are assessed either individually or in identified film groups, for content predominantly monetized on an individual basis or with other content, respectively. The substantial majority of our owned film and television costs are evaluated for impairment on an individual title basis. Programming rights that are not part of a film group are generally assessed in packages, channels, or dayparts. A daypart is an aggregation of programs broadcast during a particular time of day or programs of a similar type. Programming rights licensed by Cable Networks are primarily tested on a channel basis for impairment, whereas programming rights licensed by Broadcast Television are tested on a daypart basis. Estimated fair values of owned film and television costs or programming rights are generally based on level 3 inputs including analysis of market participant estimates of future cash flows. We record charges related to impairments or content that is substantively abandoned to programming and production costs. Impairments of capitalized film and television costs were not material in any of the periods presented. Sports Programming Rights We recognize the costs of multiyear, live-event sports programming rights as the rights are utilized over the contract term based on estimated relative value. Estimated relative value is generally based on the ratio of the current period revenue to the estimated ultimate revenue or the terms of the contract. When cash payments, including advanced payments, exceed the relative value of the programming delivered, we recognize an asset in programming rights. Production costs incurred in advance of airing are also presented in programming rights.
Earnings Per Share	Diluted earnings per common share attributable to Comcast Corporation shareholders (“diluted EPS”) considers the impact of potentially dilutive securities using the treasury stock method. Our potentially dilutive securities include potential common shares related to our stock options and our restricted share units (“RSUs”). Diluted EPS excludes the impact of potential common shares related to our stock options in periods in which the combination of the option exercise price and the associated unrecognized compensation expense is greater than the average market price of our common stock.
Recent Accounting Pronouncements	Film and Television Costs In March 2019, the Financial Accounting Standards Board (“FASB”) updated the accounting guidance related to film and television costs. The updated guidance aligned the accounting for production costs of episodic television series with those of films, allowing for costs to be capitalized in excess of amounts of revenue contracted for each episode. The guidance also updated certain presentation and disclosure requirements for capitalized film and television costs, and when content is predominantly monetized with other owned or licensed content the guidance requires impairment testing for capitalized film and television costs to be performed at a film group level and amortization to be based on usage. We adopted the updated guidance on January 1, 2020 on a prospective basis and as a result, prior period amounts were not adjusted. Following the adoption, we now present all film and television costs, including acquired programming rights previously classified as current, as noncurrent in the condensed consolidated balance sheet. The adoption of the updated accounting guidance did not have a material impact on our consolidated results of operations or financial position. See Note 4 for further information. Credit Losses In June 2016, the FASB updated the accounting guidance related to the measurement of credit losses on financial instruments, including trade receivables and loans. The updated guidance requires the recognition of credit losses on financial instruments based on an estimate of expected losses, replacing the incurred loss model in the prior guidance. We adopted the updated guidance on January 1, 2020 on a prospective basis, recording $124 million, net of tax, as a cumulative effect adjustment to retained earnings and as a result, prior period amounts were not adjusted. The adoption of the updated accounting guidance did not have a material impact on our consolidated results of operations or financial position for any periods presented.

Commitments and Contingencies	Commitments and Contingencies Redeemable Subsidiary Preferred Stock None of the holders of the Series A cumulative preferred stock of NBCUniversal Enterprise exercised their right to cause NBCUniversal Enterprise to redeem their shares during the first 30 day election period beginning March 19, 2020. As of June 30, 2020, the fair value of the NBCUniversal Enterprise redeemable subsidiary preferred stock was $728 million. The estimated fair value is based on level 2 inputs that use pricing models whose inputs are derived primarily from or corroborated by observable market data through correlation or other means for substantially the full term of the financial instrument. Contingencies We are subject to legal proceedings and claims that arise in the ordinary course of our business. While the amount of ultimate liability with respect to such actions is not expected to materially affect our results of operations, cash flows or financial position, any litigation resulting from any such legal proceedings or claims could be time-consuming and injure our reputation.

Equity Method

Atairos

Atairos follows investment company accounting and records its investments at their fair values each reporting period with the net gains or losses reflected in its statement of operations. We recognize our share of these gains and losses in equity in net income (losses) of investees, net. For the three and six months ended June 30, 2020, we recognized income of $446 million and a loss of $135 million, respectively. For the three and six months ended June 30, 2019, we recognized a loss of $106 million and income of $268 million, respectively. For the six months ended June 30, 2020 and 2019, we made cash capital contributions to Atairos totaling $172 million and $463 million, respectively. As of both June 30, 2020 and December 31, 2019, our investment in Atairos was $3.2 billion.

Hulu and Collateralized Obligation

For the three and six months ended June 30, 2020, we recognized losses of $79 million and $161 million, respectively, in equity in net income (losses) of investees, net. For the three and six months ended June 30, 2019, we recognized losses of $109 million and $250 million, respectively, and in the first quarter 2019, we recognized a previously deferred dilution gain of $159 million in other income (loss), net. For the six months ended June 30, 2019, we made cash capital contributions totaling $903 million to Hulu, inclusive of the funding to acquire our proportionate share of AT&T’s previously held 10% interest. There were no cash capital contributions made during the six months ended June 30, 2020. As of June 30, 2020 and December 31, 2019, our investment was $533 million and $694 million, respectively.

In 2019, we borrowed $5.2 billion under a term loan facility due March 2024 which is fully collateralized by the minimum guaranteed proceeds of the put/call option related to our investment in Hulu. As of June 30, 2020, both the carrying value and fair value of our collateralized obligation was $5.2 billion. The estimated fair value was based on level 2 inputs that use interest rates for debt with similar terms and remaining maturities. We present our investment in Hulu and the term loan separately in our condensed consolidated balance sheet in the captions “investment securing collateralized obligation” and “collateralized obligation,” respectively. The recorded value of our investment reflects our historical cost in applying the equity method, and as a result, is less than its fair value.

Marketable Equity Securities

Peloton

Following Peloton’s initial public offering in September 2019, we presented our investment in Peloton in marketable equity securities, which was previously presented in nonmarketable equity securities. In the second quarter of 2020, we sold our investment in Peloton. For the three and six months ended June 30, 2020, we recognized gains of $86 million and $67 million, respectively, in realized and unrealized gains (losses) on equity securities, net. As of December 31, 2019, our investment in Peloton was $294 million.

Snap

In the fourth quarter of 2019, we sold our investment in Snap. For the three and six months ended June 30, 2019, we recognized unrealized gains of $96 million and $258 million, respectively, in realized and unrealized gains (losses) on equity securities, net.

Other Investments

AirTouch

In April 2020, Verizon Americas, Inc., formerly known as AirTouch Communications, Inc. (“AirTouch”), redeemed the two series of preferred stock and we received cash payments totaling $1.7 billion. Subsequently, we redeemed and repurchased the three series of preferred shares issued by one of our consolidated subsidiaries and made cash payments totaling $1.8 billion.

As of December 31, 2019, our AirTouch investment was $1.6 billion, and the associated liability related to redeemable subsidiary preferred shares was $1.7 billion.

Recent Accounting Pronouncements	Jun. 30, 2020
Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Film and Television Costs In March 2019, the Financial Accounting Standards Board (“FASB”) updated the accounting guidance related to film and television costs. The updated guidance aligned the accounting for production costs of episodic television series with those of films, allowing for costs to be capitalized in excess of amounts of revenue contracted for each episode. The guidance also updated certain presentation and disclosure requirements for capitalized film and television costs, and when content is predominantly monetized with other owned or licensed content the guidance requires impairment testing for capitalized film and television costs to be performed at a film group level and amortization to be based on usage. We adopted the updated guidance on January 1, 2020 on a prospective basis and as a result, prior period amounts were not adjusted. Following the adoption, we now present all film and television costs, including acquired programming rights previously classified as current, as noncurrent in the condensed consolidated balance sheet. The adoption of the updated accounting guidance did not have a material impact on our consolidated results of operations or financial position. See Note 4 for further information. Credit Losses In June 2016, the FASB updated the accounting guidance related to the measurement of credit losses on financial instruments, including trade receivables and loans. The updated guidance requires the recognition of credit losses on financial instruments based on an estimate of expected losses, replacing the incurred loss model in the prior guidance. We adopted the updated guidance on January 1, 2020 on a prospective basis, recording $124 million, net of tax, as a cumulative effect adjustment to retained earnings and as a result, prior period amounts were not adjusted. The adoption of the updated accounting guidance did not have a material impact on our consolidated results of operations or financial position for any periods presented.

(a)	NBCUniversal Headquarters and Other activities include costs associated with overhead, allocations, personnel costs and headquarter initiatives.

(b)

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 Cable Networks for the sale of programming to Cable Communications; content licensing revenue in our NBCUniversal segments (Broadcast Television, Filmed Entertainment and Cable Networks) for the license of owned content to Peacock and Sky, and for licenses of owned content to other NBCUniversal segments; advertising revenue at Cable Communications, Cable Networks and Broadcast Television; and distribution revenue at Broadcast Television for fees received under retransmission consent agreements from Cable Communications. For segment reporting purposes, we account for intercompany content licenses as follows:

•

Revenue for licenses of content from NBCUniversal segments to Peacock and Sky are 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 Peacock 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 on these transactions are deferred in our consolidated results and recognized as the content is used over the license period.


•	Revenue for licenses of content between NBCUniversal segments is recognized over time to correspond with the amortization of the programming rights asset for the licensed content as the content is used over the license period.


(c)	Corporate and Other activities include costs associated with overhead and personnel, revenue and expenses associated with our other business interests, including Peacock.

(d)

We use Adjusted EBITDA as the measure of profit or loss for our operating segments. Adjusted EBITDA is defined 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. 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.

Share-Based Compensation

Our share-based compensation plans consist primarily of awards of RSUs and stock options to certain employees and directors as part of our approach to long-term incentive compensation. Additionally, through our employee stock purchase plans, employees are able to purchase shares of our common stock at a discount through payroll deductions.

In March 2020, we granted 15.8 million RSUs and 59.9 million stock options related to our annual management awards. The weighted-average fair values associated with these grants were $42.47 per RSU and $6.53 per stock option.

Segment Reporting [Abstract]

Segment Information

We present our operations in six reportable business segments: (1) Comcast Cable in one reportable business segment, referred to as Cable Communications; (2) NBCUniversal in four reportable business segments: Cable Networks, Broadcast Television, Filmed Entertainment and Theme Parks (collectively, the “NBCUniversal segments”); and (3) Sky in one reportable business segment.

Cable Communications is a leading provider of high-speed internet, 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.

Cable Networks consists primarily of our national cable networks that provide a variety of entertainment, news and information, and sports content; our regional sports and news networks; our international cable networks; our cable television studio production operations; and various digital properties.

Broadcast Television consists primarily of the NBC and Telemundo broadcast networks, our NBC and Telemundo owned local broadcast television stations, the NBC Universo national cable network, our broadcast television studio production operations, and various digital properties.

Filmed Entertainment consists primarily of the operations of Universal Pictures, which produces, acquires, markets and distributes filmed entertainment worldwide; our films are also produced under the Illumination, DreamWorks Animation and Focus Features names.

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.

Sky is one of Europe’s leading entertainment companies, which primarily includes a direct-to-consumer business, providing video, high-speed internet, voice and wireless phone services, and a content business, operating entertainment networks, the Sky News broadcast network and Sky Sports networks.

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, such as Peacock, our new direct-to-consumer streaming service that primarily features NBCUniversal content.

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 business segment is presented in the tables below.

Programming and Production Costs

Other Industries [Abstract]

Programming and Production Costs

Film and Television Costs

Cable Networks, Broadcast Television, Filmed Entertainment and Sky produce owned content or acquire the rights to programming from third parties, which are described as owned film and television costs and programming rights, respectively. We adopted new accounting guidance related to film and television costs in the first quarter of 2020 (see Note 8), and accordingly amounts presented below for periods in 2020 and the policy discussion reflect the updated accounting guidance, and amounts presented for 2019 reflect the accounting guidance in effect at that time. Under the new accounting guidance, we have determined that the predominant monetization strategy for the substantial majority of our content is on an individual basis.

Amortization of Film and Television Costs



(in millions)	Three Months Ended June 30, 2020		Six Months Ended June 30, 2020
Owned film and television costs	$	1,539	$	3,327
Programming rights	$	1,584	$	4,248

Capitalized Film and Television Costs

Capitalization and Recognition of Film and Television Costs

We capitalize costs for owned film and television content, including direct costs, production overhead, print costs, development costs and interest, as well as acquired libraries. Amortization for content predominantly monetized on an individual basis and accrued costs associated with participations and residual payments are recorded using the individual film forecast computation method, which recognizes the costs in the same ratio as the associated ultimate revenue. Estimates of ultimate revenue and total costs are based on anticipated release patterns, public acceptance and historical results for similar productions. Amortization for content predominantly monetized with other owned or licensed content is recorded based on estimated usage. In determining the method of amortization and estimated life of an acquired film or television library, we generally use the method and the life that most closely follow the undiscounted cash flows over the estimated life of the asset. We do not capitalize costs related to the distribution of a film in movie theaters or the licensing or sale of a film or television production, which primarily include costs associated with marketing and distribution.

We may enter into cofinancing arrangements with third parties to jointly finance or distribute certain of our film productions. Cofinancing arrangements can take various forms, but in most cases involve the grant of an economic interest in a film to an investor who owns an undivided copyright interest in the film. The number of investors and the terms of these arrangements can vary, although investors generally assume the full risks and rewards for the portion of the film acquired in these arrangements. We account for the proceeds received from the investor under these arrangements as a reduction of our capitalized film costs and the investor’s interest in the profit or loss of the film is recorded as either a charge or a benefit, respectively, in programming and production costs. The investor’s interest in the profit or loss of a film is recorded each period using the individual film forecast computation method.

We capitalize the costs of programming rights for content that we license but do not own when the license period begins, the content is made available for use and the costs of programming licenses are known. Programming rights are amortized as the associated programs are broadcast.

Owned film and television costs and programming rights are presented as noncurrent assets in film and television costs. We present amortization of film and television costs and accrued costs associated with participation and residual payments in programming and production costs.

When an event or a change in circumstance occurs that was known or knowable as of the balance sheet date and that indicates the fair value of either owned film and television content or programming rights is less than the unamortized costs in the balance sheet, we determine the fair value and record an impairment charge to the extent the unamortized costs exceed the fair value. Owned film and television costs are assessed either individually or in identified film groups, for content predominantly monetized on an individual basis or with other content, respectively. The substantial majority of our owned film and television costs are evaluated for impairment on an individual title basis. Programming rights that are not part of a film group are generally assessed in packages, channels, or dayparts. A daypart is an aggregation of programs broadcast during a particular time of day or programs of a similar type. Programming rights licensed by Cable Networks are primarily tested on a channel basis for impairment, whereas programming rights licensed by Broadcast Television are tested on a daypart basis. Estimated fair values of owned film and television costs or programming rights are generally based on level 3 inputs including analysis of market participant estimates of future cash flows. We record charges related to impairments or content that is substantively abandoned to programming and production costs. Impairments of capitalized film and television costs were not material in any of the periods presented.

Sports Programming Rights

We recognize the costs of multiyear, live-event sports programming rights as the rights are utilized over the contract term based on estimated relative value. Estimated relative value is generally based on the ratio of the current period revenue to the estimated ultimate revenue or the terms of the contract. When cash payments, including advanced payments, exceed the relative value of

the programming delivered, we recognize an asset in programming rights. Production costs incurred in advance of airing are also presented in programming rights.
