(in millions)	2023	2022		2023	2022
Weighted-average number of common shares outstanding – basic	4,109	4,377		4,160	4,449

Weighted-average number of common shares outstanding – diluted	4,141	4,377		4,184	4,477

Antidilutive securities	86	288		172	156

Diluted earnings per common share attributable to Comcast Corporation shareholders (“diluted EPS”) considers the impact of potentially dilutive securities using the treasury stock method. There were no potentially dilutive shares included for the three months ended September 30, 2022 because their effect would be antidilutive as a result of the loss for the period. Antidilutive securities represent the number of potential common shares related to share-based compensation awards that were excluded from diluted EPS because their effect would have been antidilutive.

Share-Based Compensation

Our share-based compensation plans consist primarily of awards of restricted share units (“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 2023, we granted 22 million RSUs and 57 million stock options related to our annual management awards. The weighted-average fair values associated with these grants were $36.62 per RSU and $8.33 per stock option.

During the three months ended September 30, 2023 and 2022, share-based compensation expense recognized in our condensed consolidated statements of income was $238 million and $256 million, respectively. During the nine months ended September 30, 2023 and 2022, share-based compensation expense recognized in our condensed consolidated statements of income was $786 million and $802 million, respectively. As of September 30, 2023, we had unrecognized pretax compensation expense of $2.2 billion related to nonvested RSUs and nonvested stock options.

Condensed Consolidated Financial Statements (Policies)	Sep. 30, 2023
Organization, Consolidation and Presentation of Financial Statements [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 2022 Annual Report on Form 10-K.
Reclassifications	Reclassifications have been made to our notes to condensed consolidated financial statements for the prior year periods to conform to classifications used in 2023.
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. There were no potentially dilutive shares included for the three months ended September 30, 2022 because their effect would be antidilutive as a result of the loss for the period. Antidilutive securities represent the number of potential common shares related to share-based compensation awards that were excluded from diluted EPS because their effect would have been antidilutive.

(a)Included in Eliminations are transactions that our segments enter into with one another. The most significant of these transactions include distribution revenue in Media related to fees from Residential Connectivity & Platforms for the rights to distribute television programming and content licensing revenue in Studios for licenses of owned content to Media. Revenue for licenses of content from Studios to Media 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 in Media 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.

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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Condensed Consolidated Financial Statements	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 2022 Annual Report on Form 10-K. Reclassifications Reclassifications have been made to our notes to condensed consolidated financial statements for the prior year periods to conform to classifications used in 2023. See Note 2 for a discussion of the changes in our presentation of segment operating results.

In the third quarter of 2022, we recorded a goodwill impairment of $8.1 billion in our Sky reporting unit. The fair value of the reporting unit was estimated using a discounted cash flow analysis. When performing this analysis, we also considered multiples of earnings from comparable public companies and recent market transactions. The decline in fair value primarily resulted from an increased discount rate and reduced estimated future cash flows as a result of macroeconomic conditions in the Sky territories. In connection with this assessment, in the third quarter of 2022, we also recorded impairments of intangible assets related to Sky, which primarily related to customer relationship assets. These impairments totaled $485 million and are presented in goodwill and long-lived asset impairments in the consolidated statement of income.

Debt Disclosure [Abstract]
Long-Term Debt	Long-Term DebtAs of September 30, 2023, our debt had a carrying value of $97.3 billion and an estimated fair value of $85.5 billion. As of December 31, 2022, our debt had a carrying value of $94.8 billion and an estimated fair value of $86.9 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.

Segment Information

Segment Reporting [Abstract]

Segment Information

Beginning in the first quarter of 2023, we changed our presentation of segment operating results around our two primary businesses: Connectivity & Platforms and Content & Experiences.

Connectivity & Platforms: Contains our broadband and wireless connectivity businesses operated under the Xfinity and Comcast brands in the United States and under the Sky brand in certain territories in Europe (the “Connectivity & Platforms markets”). Also includes our video services businesses and the operations of our Sky-branded entertainment television channels in the Connectivity & Platforms markets. Our Connectivity & Platforms business is reported in two reportable business segments:

•Residential Connectivity & Platforms Segment: Includes our residential broadband and wireless connectivity services, residential and business video services, advertising sales and Sky channels. Revenue is generated primarily from customers that subscribe to our services and from the sale of advertising and wireless devices.

•Business Services Connectivity Segment: Includes our connectivity services for small business locations in the United States, which include broadband, voice and wireless services, as well as our solutions for medium-sized customers and larger enterprises, and our small business connectivity service offerings for international locations. Revenue is generated primarily from customers that subscribe to our services.

Content & Experiences: Contains our media and entertainment businesses that develop, produce, and distribute entertainment, news and information, sports, and other content for global audiences and that own and operate theme parks in the United States and Asia. Our Content & Experiences business is reported in three reportable business segments:

•Media Segment: Includes primarily NBCUniversal’s television and streaming business, including national and regional cable networks; the NBC and Telemundo broadcast networks; NBC and Telemundo owned local broadcast television stations; and Peacock, our direct-to-consumer streaming service. Also includes international networks, including most of the Sky Sports channels, and other digital properties. Revenue is generated primarily from the distribution of our television and streaming programming and from the sale of advertising on our television networks, Peacock and other digital properties.

•Studios Segment: Includes primarily our NBCUniversal and Sky film and television studio production and distribution operations. Revenue is generated primarily from licensing our owned film and television content in the United States and internationally; and from the worldwide distribution of our produced and acquired films for exhibition in movie theaters.

•Theme Parks Segment: Includes primarily the operations of our Universal theme parks in Orlando, Florida; Hollywood, California; Osaka, Japan; and Beijing, China. Revenue is generated primarily from guest spending at our theme parks.

Our other business interests consist primarily of Sky operations outside of the Connectivity & Platforms markets, the operations of Comcast Spectacor, which owns the Philadelphia Flyers and the Wells Fargo Center arena in Philadelphia, Pennsylvania, and the operations of Xumo, our consolidated streaming platform joint venture with Charter Communications formed in June 2022.

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. Transactions between our Connectivity & Platforms and Content & Experiences businesses, and between segments within the Content & Experiences business, generally include intercompany profit consistent with third-party transactions. The segments within our Connectivity & Platforms business use certain shared infrastructure, including the cable distribution network in the United States, and each segment is presented with its direct costs and an allocation of shared costs, as well as revenue from its customers.

Equity Method Investments

The amount of cash distributions received from equity method investments presented within operating activities in the condensed consolidated statements of cash flows in the nine months ended September 30, 2023 and 2022 was $185 million and $114 million, respectively.

Atairos

Atairos is a variable interest entity (“VIE”) that 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 nine months ended September 30, 2023 and 2022, we made cash capital contributions to Atairos totaling $132 million and $39 million, respectively. As of September 30, 2023 and December 31, 2022, our investment in Atairos, inclusive of certain distributions retained by Atairos on our behalf and classified as advances within other investments, was $5.1 billion and $4.3 billion, respectively. As of September 30, 2023, our remaining unfunded capital commitment was $1.4 billion.

Hulu and Collateralized Obligation

In the third quarter of 2023, we amended our agreements with The Walt Disney Company and certain of its subsidiaries regarding our ownership interest in Hulu and the related put and call provisions. As part of the amendments, among other things, we agreed that the put/call provisions regarding our interest may now be exercised in November 2023 (in addition to subsequent periods).

In 2019, we borrowed $5.2 billion under a term loan facility, which is fully collateralized by the minimum guaranteed proceeds of the put/call option related to our investment in Hulu. The term loan is due at the earlier of March 2024 or upon receipt of proceeds under the put/call provisions. As of both September 30, 2023 and December 31, 2022, the carrying value and estimated fair value of our collateralized obligation were each $5.2 billion. The estimated fair values were 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 sheets 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.

Other Investments

Other investments also includes investments in certain short-term instruments with maturities over three months when purchased, such as commercial paper, certificates of deposit and U.S. government obligations, which are generally accounted for at amortized cost. These short-term instruments totaled $253 million and $304 million as of September 30, 2023 and December 31, 2022, respectively. The carrying amounts of these investments approximate their fair values, which are primarily based on Level 2 inputs that use interest rates for instruments with similar terms and remaining maturities. Proceeds from short-term instruments for the nine months ended September 30, 2023 and 2022 were $339 million and $874 million, respectively. Purchases of short-term instruments for the nine months ended September 30, 2023 and 2022 were $286 million and $1.8 billion, respectively.

Consolidated Variable Interest Entity

Universal Beijing Resort

We own a 30% interest in a Universal theme park and resort in Beijing, China (“Universal Beijing Resort”), which opened in September 2021. Universal Beijing Resort is a consolidated VIE with the remaining interest owned by a consortium of Chinese state-owned companies. The construction was funded through a combination of debt financing and equity contributions from the partners in accordance with their equity interests. As of September 30, 2023, Universal Beijing Resort had $3.4 billion of debt outstanding, including $3.0 billion principal amount of a term loan outstanding under the debt financing agreement.

As of September 30, 2023, our condensed consolidated balance sheets included assets and liabilities of Universal Beijing Resort totaling $7.8 billion and $7.1 billion, respectively. The assets and liabilities of Universal Beijing Resort primarily consist of property and equipment, operating lease assets and liabilities, and debt.
