Organization and Basis of Presentation [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Organization Charter Communications, Inc. (together with its controlled subsidiaries, “Charter,” or the “Company”) is the second largest cable operator in the United States and a leading broadband communications services company providing video, Internet and voice services to residential and small and medium business customers. The Company also offers mobile service to residential customers and recently launched mobile service to small and medium business customers. In addition, the Company sells video and online advertising inventory to local, regional and national advertising customers and tailored communications and managed solutions to larger enterprise customers. The Company also owns and operates regional sports networks and local sports, news and community channels. Charter is a holding company whose principal asset is a controlling equity interest in Charter Communications Holdings, LLC (“Charter Holdings”), an indirect owner of Charter Communications Operating, LLC (“Charter Operating”) under which substantially all of the operations reside. All significant intercompany accounts and transactions among consolidated entities have been eliminated. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Areas involving significant judgments and estimates include capitalization of labor and overhead costs, impairments of franchises and goodwill, pension benefits and income taxes. Actual results could differ from those estimates. Certain prior period amounts have been reclassified to conform with the 2019 presentation.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Consolidation The accompanying consolidated financial statements include the accounts of Charter and all entities in which Charter has a controlling interest, including variable interest entities ("VIEs") where Charter is the primary beneficiary. The Company consolidates based upon evaluation of the Company’s power, through voting rights or similar rights, to direct the activities of another entity that most significantly impact the entity’s economic performance; its obligation to absorb the expected losses of the entity; and its right to receive the expected residual returns of the entity. Charter controls and consolidates Charter Holdings. The noncontrolling interest on the Company’s balance sheet primarily represents Advance/Newhouse Partnership's (“A/N”) minority equity interests in Charter Holdings. See Note 11. All significant intercompany accounts and transactions among consolidated entities have been eliminated in consolidation. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. These investments are carried at cost, which approximates market value. Restricted Cash Restricted cash represents amounts held in escrow related to the Company's build-to-suit lease arrangement with a VIE. See Note 6. The amounts held in escrow are classified as noncurrent restricted cash in the Company's consolidated balance sheets. The Company's restricted cash was primarily invested in a federal funds deposit account. Property, Plant and Equipment Additions to property, plant and equipment are recorded at cost, including all material, labor and certain indirect costs associated with the construction of cable transmission and distribution facilities. While the Company’s capitalization is based on specific activities, once capitalized, costs are tracked on a composite basis by fixed asset category at the cable system level and not on a specific asset basis. For assets that are sold or retired, the estimated historical cost and related accumulated depreciation is removed. Costs associated with the placement of the customer drop to the dwelling and the placement of outlets within a dwelling along with the costs associated with the deployment of new customer premise equipment necessary to provide video, Internet or voice services are capitalized. Costs capitalized include materials, direct labor and overhead costs. The Company capitalizes direct labor and overhead using standards developed from actual costs and applicable operational data. The Company calculates standards annually (or more frequently if circumstances dictate) for items such as the labor rates, overhead rates, and the actual amount of time required to perform a capitalizable activity. Overhead costs are associated with the activities of the Company’s personnel who assist in installation activities and consist of compensation and other indirect costs associated with these support functions. Indirect costs primarily include employee benefits and payroll taxes, and vehicle and occupancy costs. The costs of disconnecting service and removing customer premise equipment from a dwelling and the costs to reconnect a customer drop or to redeploy previously installed customer premise equipment are charged to operating expense as incurred. Costs for repairs and maintenance are charged to operating expense as incurred, while plant and equipment replacement, including replacement of certain components, betterments, including replacement of cable drops and outlets, are capitalized. Depreciation is recorded using the straight-line composite method over management’s estimate of the useful lives of the related assets as follows: Cable distribution systems 8-20 years Customer premise equipment and installations 3-8 years Vehicles and equipment 6-21 years Buildings and improvements 10-40 years Furniture, fixtures and equipment 2-10 years Asset Retirement Obligations Certain of the Company’s franchise agreements and leases contain provisions requiring the Company to restore facilities or remove equipment in the event that the franchise or lease agreement is not renewed. The Company expects to continually renew its franchise agreements and therefore cannot reasonably estimate any liabilities associated with such agreements. A remote possibility exists that franchise agreements could be terminated unexpectedly, which could result in the Company incurring significant expense in complying with restoration or removal provisions. The Company does not have any significant liabilities related to asset retirements recorded in its consolidated financial statements. Valuation of Long-Lived Assets The Company evaluates the recoverability of long-lived assets (e.g., property, plant and equipment and finite-lived intangible assets) to be held and used when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Such events or changes in circumstances could include such factors as impairment of the Company’s indefinite life assets, changes in technological advances, fluctuations in the fair value of such assets, adverse changes in relationships with local franchise authorities, adverse changes in market conditions or a deterioration of current or expected future operating results. If a review indicates that the carrying value of such asset is not recoverable from estimated undiscounted cash flows, the carrying value of such asset is reduced to its estimated fair value. While the Company believes that its estimates of future cash flows are reasonable, different assumptions regarding such cash flows could materially affect its evaluations of asset recoverability. No impairments of long-lived assets held for use were recorded in 2019 , 2018 and 2017 . For non-strategic long-lived assets held for sale and ultimately sold, the Company recorded impairments of approximately $41 million and $75 million during the years ended December 31, 2019 and 2018, respectively, to other operating expenses, net. Leases The primary leased asset classes of the Company include real estate, dark fiber, colocation facilities and other equipment. The lease agreements include both lease and non-lease components, which the Company accounts for separately depending on the election made for each leased asset class. For real estate and dark fiber leased asset classes, the Company accounts for lease and non-lease components as a single lease component and includes all fixed payments in the measurement of lease liabilities and lease assets. For colocation facilities leased asset class, the Company accounts for lease and non-lease components separately including only the fixed lease payment component in the measurement of lease liabilities and lease assets. In addition to fixed lease payments, certain of the Company’s lease agreements include variable lease payments which are tied to an index or rate such as the change in the Consumer Price Index. These variable payments are not included in the measurement of the lease liabilities and lease assets. Lease assets and lease liabilities are initially recognized based on the present value of the future lease payments over the expected lease term. As for most leases the implicit rate is not readily determinable, the Company uses a discount rate in determining the present value of future payments based on the yield-to-maturity of the Company’s secured publicly traded United States dollars denominated debt instruments interpolating the duration of the debt to the term of the executed lease. The Company’s leases have base rent periods and some with optional renewal periods. Leases with base rent periods of less than 12 months are not recorded on the balance sheet. For purposes of measurement of lease liabilities, the expected lease terms may include renewal options when it is reasonably certain that the Company will exercise such options. Based on conditions of the Company's existing leases and its overall business strategies, the majority of the Company's renewal options are not reasonably certain in determining the expected lease term. The Company will periodically reassess expected lease terms (and purchase options, if applicable) based on significant triggering events or compelling economic reasons to exercise such options. The Company’s primary lease income represents sublease income on certain real estate leases. Sublease income is included in other revenue and presented gross from rent expense. For customer premise equipment ("CPE") where such CPE would qualify as a lease, the Company applies the practical expedient to combine the operating lease with the subscription service revenue as a single performance obligation in accordance with revenue recognition accounting guidance as the subscription service is the predominant component. Other Noncurrent Assets Other noncurrent assets primarily include investments, trademarks, customer contract costs and other intangible assets. The Company accounts for its investments in less than majority owned investees under either the equity method or as equity securities. The Company applies the equity method to investments when it has the ability to exercise significant influence over the operating and financial policies of the investee. The Company’s share of the investee’s earnings (losses) is included in other expense, net in the consolidated statements of operations. The Company monitors its investments for indicators that a decrease in investment value has occurred that is other than temporary. If it has been determined that an investment has sustained an other than temporary decline in value, the investment is written down to fair value with a charge to earnings. Investments acquired are measured at fair value utilizing the acquisition method of accounting. The difference between the fair value and the amount of underlying equity in net assets for most equity method investments is due to previously unrecognized intangible assets at the investee. These amounts are amortized as a component of equity earnings (losses), recorded within other expense, net over the estimated useful life of the asset. Trademarks have been determined to have an indefinite life and are tested annually for impairment. Customer contract costs are deferred in other noncurrent assets for upfront costs incurred to obtain a customer contract and upfront costs to fulfill a customer contract, as further discussed below under the Customer Contract Costs accounting policy. Revenue Recognition Nature of Services Residential Services Residential customers are offered video, Internet, and voice services primarily on a subscription basis. Residential customers may generally cancel their subscriptions at the end of their monthly service period without penalty. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized ratably over the monthly service period as the subscription services are delivered. Each optional service purchased is generally accounted for as a distinct performance obligation when purchased and revenue is recognized when the service is provided. Residential video customers have the option to purchase additional tiers of services, as well as video-on-demand (“VOD”) programming and pay-per-view programming on a per-event basis. Video revenues consist primarily of revenues from the selected programming service tier, as well as VOD fees, pay-per-view fees, retransmission fees, regulatory fees, equipment service fees and video installation fees. Residential Internet customers receive data download and upload services with speeds dependent on the selected tier of service. Customers are also offered a security suite, an in-home WiFi product, and an out-of-home WiFi service. Internet revenues consist primarily of data services, WiFi service fees and Internet installation fees. Residential voice customers receive unlimited local and long distance calling to United States, Canada, Mexico, and Puerto Rico, voicemail, call waiting, caller ID, call forward and other features. Customers may also purchase international calling either by the minute, or through packages of minutes per month. Voice revenues consist primarily of voice services and regulatory fees. Small and Medium Business Small and medium business customers are offered video, Internet and voice services similar to those provided to residential customers. Small and medium business customers may generally cancel their subscriptions at the end of their monthly service period without penalty. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized ratably over the monthly service period as the subscription services are delivered. Enterprise Services to enterprise clients include more tailored communications products and managed service solutions to larger businesses, as well as high-capacity last-mile data connectivity services to mobile and wireline carriers on a wholesale basis. Services are primarily offered on a subscription basis with a contractually specified and non-cancelable service period. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized ratably over the contract period as the subscription services are delivered. Enterprise subscription services are billed as monthly recurring charges to customers and related installation services, if applicable, are billed upon completion of the customer installation. Installation services are not accounted for as distinct performance obligations, but rather a component of the connectivity services, and therefore upfront installation fees are deferred and recognized as revenue over the related contract period. Advertising Services The Company offers local, regional and national businesses the opportunity to advertise in individual and multiple service areas on cable television networks and digital outlets. Placement of advertising is accounted for as a distinct performance obligation and revenue is recognized at the point in time when the advertising is distributed. In some service areas, the Company has formed advertising interconnects or entered into representation agreements with other video distributors, under which the Company sells advertising on behalf of those distributors. In other service areas, the Company has entered into representation agreements under which another operator in the area will sell advertising on the Company’s behalf. For representation arrangements in which the Company controls the sale of advertising and acts as the principal to the transaction, the Company recognizes revenue earned from the advertising customer on a gross basis and the amount remitted to the distributor as an operating expense. For other representation arrangements in which the Company does not control the sale of advertising and acts as an agent to the transaction, the Company recognizes revenue net of any fee remitted to the distributor. Mobile We also offer mobile service to residential customers and recently launched mobile service to small and medium business customers. Mobile services are sold under an unlimited data plan or a by-the-gig data usage plan and revenue is recognized ratably over the monthly service period as the services are delivered. Customers can purchase mobile equipment, including devices and accessory products, and have the option to pay for devices under interest-free monthly installment plans. The sale of equipment is a separate performance obligation. Revenue is recognized from the sale of equipment upon delivery and acceptance by the customer, as this is when control passes to the customer. The Company’s revenues by product line are as follows: Year Ended December 31, 2019 2018 2017 Video $ 17,607 $ 17,348 $ 16,621 Internet 16,667 15,181 14,101 Voice 1,920 2,114 2,542 Residential revenue 36,194 34,643 33,264 Small and medium business 3,868 3,665 3,547 Enterprise 2,556 2,528 2,373 Commercial revenue 6,424 6,193 5,920 Advertising sales 1,568 1,785 1,510 Mobile 726 106 — Other 852 907 887 $ 45,764 $ 43,634 $ 41,581 Fees imposed on the Company by various governmental authorities are passed through on a monthly basis to the Company’s customers and are periodically remitted to authorities. Fees of $1.1 billion , $1.0 billion and $961 million for the years ended December 31, 2019 , 2018 and 2017 , respectively, are reported in video, voice, mobile and commercial revenues, on a gross basis with a corresponding operating expense because the Company is acting as a principal. Certain taxes, such as sales taxes imposed on the Company’s customers, collected and remitted to state and local authorities, are recorded on a net basis because the Company is acting as an agent in such situations. A significant portion of our revenue is derived from customers who may generally cancel their monthly subscriptions at any time without penalty. As such, the amount of revenue related to unsatisfied performance obligations is not necessarily indicative of the future revenue to be recognized from our existing customer base. Revenue from customers with a contractually specified term and non-cancelable service period will be recognized over the term of such contracts, which is generally two to seven years for our enterprise contracts with a weighted average term of approximately three years. Significant Judgments in Evaluating Revenue Recognition The Company often provides multiple services to a customer. Provision of customer premise equipment, installation services, and additional service tiers may have a significant level of integration and interdependency with the subscription video, Internet, voice, or connectivity services provided. Judgment is required to determine whether provision of customer premise equipment, installation services, and additional service tiers are considered distinct and accounted for separately, or not distinct and accounted for together with the subscription services. Allocation of the transaction price to the distinct performance obligations in bundled residential service subscriptions requires judgment. The transaction price for a bundle of residential services is frequently less than the sum of the standalone selling prices of each individual service. The Company allocates the residential services bundle discount among the services to which the discount relates based on the relative standalone selling prices of those services. Standalone selling prices for the Company’s residential video and Internet services are directly observable, while standalone selling price for the Company’s residential voice service is estimated using the adjusted market assessment approach which relies upon information from peers and competitors who sell residential voice services individually. The Company believes residential and small and medium business non-refundable upfront installation fees charged to customers result in a material right to renew the contract as such fees are not required to be paid upon subsequent renewals. The residential and small and medium business upfront fee is deferred over the period the fee remains material to the customer, which the Company has estimated to be approximately six months. Estimation of the period the fee remains material to the customer requires consideration of both quantitative and qualitative factors including average installation fee, average revenue per customer, and customer behavior, among others. Deferred Revenue Contract Liabilities Timing of revenue recognition may differ from the timing of invoicing to customers. Residential, small and medium business, and enterprise customers are invoiced for subscription services in advance of the service period. Deferred revenue liabilities, or contract liabilities, are recorded when the Company collects payments in advance of performing the services. Deferred revenue liabilities, or contract liabilities, are also recorded when the Company invoices customers upfront for installation services that are recognized as revenue over time. Residential and small and medium business installation revenues are deferred over the period the fee remains material to the customer. Enterprise installation revenues are deferred using a portfolio approach over the average contract life of each enterprise service category. As of December 31, 2019 and 2018 , current deferred revenue liabilities consisting of customer prepayments of $366 million and $410 million , respectively, and upfront installation fees of $94 million and $84 million , respectively, were included in accounts payable and accrued liabilities. As of December 31, 2019 and 2018 , long-term deferred revenue liabilities consisting of enterprise upfront installation fees of $34 million were included in other long-term liabilities. Customer Contract Costs The Company recognizes an asset for incremental costs of obtaining a contract with a customer if the amortization period of those costs is expected to be longer than one year and the costs are expected to be recovered. Enterprise sales commission costs meet the requirements to be deferred and, as a result, are recognized using a portfolio approach over a commission expense weighted-average enterprise contract period. Deferred enterprise commission costs are included in other noncurrent assets in the consolidated balance sheet and totaled $143 million and $142 million as of December 31, 2019 and 2018 , respectively. As the amortization period of residential and small and medium business commissions costs is less than one year, the Company applies the practical expedient that allows such costs to be expensed as incurred. The Company has determined that the amortization period associated with residential and small and medium business commission costs is less than one year based on qualitative and quantitative factors. The Company recognizes an asset for costs incurred to fulfill a contract when those costs are directly related to services provided under the contract, generate or enhance resources of the entity that will be used in performing service obligations under the contract, and are expected to be recovered. Right-of-entry costs represent upfront costs incurred related to agreements entered into with multiple dwelling units (“MDUs”) including landlords, real estate companies or owners to gain access to a building in order to market and service customers who reside in the building. Right-of-entry costs meet the requirements to be deferred and, as a result, are recognized over the term of the contracts. Deferred right-of-entry costs are included in other noncurrent assets in the consolidated balance sheet and totaled $284 million and $273 million as of December 31, 2019 and 2018 , respectively. Amortization expense of $67 million and $62 million was included in regulatory, connectivity and produced content within operating costs and expenses in the consolidated statements of operations for the year ended December 31, 2019 and 2018 , respectively. Residential and small and medium business installation costs not capitalized into property, plant and equipment are expensed as incurred under cable industry-specific guidance. Programming Costs The Company has various contracts to obtain video programming from vendors whose compensation is typically based on a flat fee per customer. The cost of the right to exhibit network programming under such arrangements is recorded in operating expenses in the month the programming is available for exhibition. Programming costs are paid each month based on calculations performed by the Company and are subject to periodic audits performed by the programmers. Certain programming contracts contain cash and non-cash consideration from the programmers. If consideration received does not relate to a separate product or service, the Company recognizes the consideration on a straight-line basis over the life of the programming agreement as a reduction of programming expense. Programming costs included in the statements of operations were $11.3 billion , $11.1 billion and $10.6 billion for the years ended December 31, 2019 , 2018 and 2017 , respectively. Advertising Costs Advertising costs associated with marketing the Company’s products and services are generally expensed as costs are incurred. Multiple-Element Transactions In the normal course of business, the Company enters into multiple-element transactions where it is simultaneously both a customer and a vendor with the same counterparty or in which it purchases multiple products and/or services, or settles outstanding items contemporaneous with the purchase of a product or service from a single counterparty. Transactions, although negotiated contemporaneously, may be documented in one or more contracts. The Company’s policy for accounting for each transaction negotiated contemporaneously is to record each element of the transaction based on the respective estimated fair values of the products or services purchased and the products or services sold. In determining the fair value of the respective elements, the Company refers to quoted market prices (where available), historical transactions or comparable cash transactions. Cash consideration received from a vendor is recorded as a reduction in the price of the vendor’s product unless (i) the consideration is for the reimbursement of a specific, incremental, identifiable cost incurred, in which case the cash consideration received would be recorded as a reduction in such cost (e.g., marketing costs), or (ii) an identifiable benefit in exchange for the consideration is provided, in which case revenue would be recognized for this element. Stock-Based Compensation Restricted stock, restricted stock units, stock options as well as equity awards with market conditions are measured at the grant date fair value and amortized to stock compensation expense over the requisite service period. The fair value of options is estimated on the date of grant using the Black-Scholes option-pricing model and the fair value of equity awards with market conditions is estimated on the date of grant using Monte Carlo simulations. The grant date weighted average assumptions used during the years ended December 31, 2019 , 2018 and 2017 , respectively, were: risk-free interest rate of 2.5% , 2.4% and 1.8% ; expected volatility of 27% , 25% and 25% ; and expected lives of 4.9 years, 5.1 years and 4.6 years. The Company’s volatility assumptions represent management’s best estimate and were based on historical volatility. Expected lives were estimated using historical exercise data. The valuations assume no dividends are paid. The Company has elected an accounting policy to assume zero forfeitures for stock awards grants and account for forfeitures when they occur. Defined Benefit Pension Plans The Company sponsors three qualified defined benefit pension plans and one nonqualified defined benefit pension plan that provide pension benefits to a majority of employees who were employed by Time Warner Cable Inc. ("TWC") before the merger with TWC. Pension benefits are based on formulas that reflect the employees’ years of service and compensation during their employment period. Actuarial gains or losses are changes in the amount of either the benefit obligation or the fair value of plan assets resulting from experience different from that assumed or from changes in assumptions. The Company has elected to follow a mark-to-market pension accounting policy for recording the actuarial gains or losses annually during the fourth quarter, or earlier if a remeasurement event occurs during an interim period. Income Taxes The Company recognizes deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities and expected benefits of utilizing loss carryforwards. Since substantially all the Company’s operations are held through its partnership interest in Charter Holdings, the primary deferred tax component recorded in the consolidated balance sheet relates to the excess financial reporting outside basis, excluding amounts attributable to nondeductible goodwill, over Charter’s tax basis in its investment in the partnership. Valuation allowances are established when management determines that it is more likely than not that some portion or the entire deferred tax asset will not be realized. The impact on deferred taxes of changes in tax rates and tax law, if any, applied to the years during which temporary differences are expected to be settled, are reflected in the consolidated financial statements in the period of enactment. In determining the Company’s tax provision for financial reporting purposes, the Company establishes a reserve for uncertain tax positions unless such positions are determined to be “more likely than not” of being sustained upon examination, based on their technical merits. There is considerable judgment involved in making such a determination. Interest and penalties are recognized on uncertain income tax positions as part of the income tax provision. See Note 17. Segments The Company’s operations are managed and reported to its Chief Executive Officer (“CEO”), the Company’s chief operating decision maker, on a consolidated basis. The CEO assesses performance and allocates resources based on the consolidated results of operations. Under this organizational and reporting structure, the Company has one

A significant change in assumptions about the extent or timing of future asset retirements, or in the Company’s use of new technology and upgrade programs, could materially affect future depreciation expense. Depreciation expense for the years ended December 31, 2019 , 2018 and 2017 was $7.8 billion , $7.9 billion , and $7.8 billion

Franchises, Goodwill and Other

Franchises, Goodwill and Other Intangible Assets (Notes)	12 Months Ended

Goodwill and Intangible Assets Disclosure [Abstract]
Franchises, Goodwill and Other Intangible Assets	Franchises, Goodwill and Other Intangible Assets Franchise rights represent the value attributed to agreements or authorizations with local and state authorities that allow access to homes in cable service areas. For valuation purposes, they are defined as the future economic benefits of the right to solicit and service potential customers (customer marketing rights), and the right to deploy and market new services to potential customers (service marketing rights). Management estimates the fair value of franchise rights at the date of acquisition and determines if the franchise has a finite life or an indefinite life. The Company has concluded that all of its franchises qualify for indefinite life treatment given that there are no legal, regulatory, contractual, competitive, economic or other factors which limit the period over which these rights will contribute to the Company's cash flows. The Company reassesses this determination periodically or whenever events or substantive changes in circumstances occur. All franchises are tested for impairment annually or more frequently as warranted by events or changes in circumstances. Franchise assets are aggregated into essentially inseparable units of accounting to conduct valuations. The units of accounting generally represent geographical clustering of the Company's cable systems into groups. The Company assesses qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that an indefinite lived intangible asset has been impaired. If, after this optional qualitative assessment, the Company determines that it is not more likely than not that an indefinite lived intangible asset has been impaired, then no further quantitative testing is necessary. In completing the qualitative impairment testing, the Company evaluates a multitude of factors that affect the fair value of our franchise assets. Examples of such factors include environmental and competitive changes within our operating footprint, actual and projected operating performance, the consistency of our operating margins, equity and debt market trends, including changes in our market capitalization, and changes in our regulatory and political landscape, among other factors. The Company performed a qualitative assessment in 2019 , which also included consideration of a fair value appraisal performed for tax purposes in the beginning of 2019 as of a December 31, 2018 valuation date (the "Appraisal"). After consideration of the qualitative factors in 2019 , including the results of the Appraisal, the Company concluded that it is more likely than not that the fair value of the franchise assets in each unit of accounting exceeds the carrying value of such assets and therefore did not perform a quantitative analysis at the assessment date. Periodically, the Company will elect to perform a quantitative analysis for impairment testing. If the Company elects or is required to perform a quantitative analysis to test its franchise assets for impairment, the methodology described below is utilized. If a quantitative analysis is performed, the estimated fair value of franchises is determined utilizing an income approach model based on the present value of the estimated discrete future cash flows attributable to each of the intangible assets identified assuming a discount rate. The fair value of franchises is determined based on estimated discrete discounted future cash flows using assumptions consistent with internal forecasts. The franchise after-tax cash flow is calculated as the after-tax cash flow generated by the potential customers obtained. The sum of the present value of the franchises’ after-tax cash flow in years 1 through 10 and the continuing value of the after-tax cash flow beyond year 10 yields the fair value of the franchises. This approach makes use of unobservable factors such as projected revenues, expenses, capital expenditures, customer trends, and a discount rate applied to the estimated cash flows. The determination of the franchise discount rate is derived from the Company’s weighted average cost of capital, which uses a market participant’s cost of equity and after-tax cost of debt and reflects the risks inherent in the cash flows. The Company estimates discounted future cash flows using reasonable and appropriate assumptions including among others, penetration rates; revenue growth rates; operating margins; and capital expenditures. The assumptions are based on the Company’s and its peers’ historical operating performance adjusted for current and expected competitive and economic factors surrounding the cable industry. The estimates and assumptions made in the Company’s valuations are inherently subject to significant uncertainties, many of which are beyond its control, and there is no assurance that these results can be achieved. The primary assumptions for which there is a reasonable possibility of the occurrence of a variation that would significantly affect the measurement value include the assumptions regarding revenue growth, programming expense growth rates, the amount and timing of capital expenditures, actual customer trends and the discount rate utilized. The Company has determined that it has one reporting unit for purposes of the assessment of goodwill impairment. The fair value of the reporting unit is determined using both an income approach and market approach. The Company’s income approach model used for its reporting unit valuation is consistent with that used for its franchise valuation noted above except that cash flows from the entire business enterprise are used for the reporting unit valuation. The Company’s market approach model estimates the fair value of the reporting unit based on market prices in actual precedent transactions of similar businesses and market valuations of guideline public companies. Goodwill is tested for impairment as of November 30 of each year , or more frequently as warranted by events or changes in circumstances. Accounting guidance also permits an optional qualitative assessment for goodwill to determine whether it is more likely than not that the carrying value of a reporting unit exceeds its fair value. If, after this qualitative assessment, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount then no further quantitative testing would be necessary. A quantitative assessment is performed if the qualitative assessment results in a more likely than not determination or if a qualitative assessment is not performed. The quantitative assessment considers whether the carrying amount of a reporting unit exceeds its fair value, in which case an impairment charge is recorded to the extent the reporting unit’s carrying value exceeds its fair value. As with the Company’s franchise impairment testing, in 2019 the Company elected to perform a qualitative goodwill impairment assessment, which incorporated the results of the Appraisal and consideration of the same qualitative factors relevant to the Company's franchise impairment testing. As a result of that assessment, the Company concluded that goodwill is not impaired. Customer relationships are recorded at fair value as of the date acquired less accumulated amortization. Customer relationships, for valuation purposes, represent the value of the business relationship with existing customers, and are calculated by projecting the discrete future after-tax cash flows from these customers, including the right to deploy and market additional services to these customers. The present value of these after-tax cash flows yields the fair value of the customer relationships. The use of different valuation assumptions or definitions of franchises or customer relationships, such as our inclusion of the value of selling additional services to our current customers within customer relationships versus franchises, could significantly impact our valuations and any resulting impairment. Customer relationships are amortized on an accelerated sum of years’ digits method over useful lives of 8 - 15 years based on the period over which current customers are expected to generate cash flows. The Company periodically evaluates the remaining useful lives of its customer relationships to determine whether events or circumstances warrant revision to the remaining periods of amortization. Customer relationships are evaluated for impairment upon the occurrence of events or changes in circumstances indicating that the carrying amount of an asset may not be recoverable. Customer relationships are deemed impaired when the carrying value exceeds the projected undiscounted future cash flows associated with the customer relationships. No impairment of customer relationships was recorded in the years ended December 31, 2019 , 2018 or 2017 . The fair value of trademarks is determined using the relief-from-royalty method, a variation of the income approach, which applies a fair royalty rate to estimated revenue derived under the Company’s trademarks. The fair value of the intangible is estimated to be the present value of the royalty saved because the Company owns the trademarks. Royalty rates are estimated based on a review of market royalty rates in the communications and entertainment industries. As the Company expects to continue to use each trademark indefinitely, trademarks have been assigned an indefinite life and are tested annually for impairment using either a qualitative analysis or quantitative analysis as elected by management. As with the Company’s franchise impairment testing, in 2019 the Company elected to perform a qualitative trademark impairment assessment and concluded that trademarks are not impaired. As of December 31, 2019 and 2018 , indefinite-lived and finite-lived intangible assets are presented in the following table: December 31, 2019 2018 Gross Carrying Amount Accumulated Amortization Net Carrying Amount Gross Carrying Amount Accumulated Amortization Net Carrying Amount Indefinite-lived intangible assets: Franchises $ 67,322 $ — $ 67,322 $ 67,319 $ — $ 67,319 Goodwill 29,554 — 29,554 29,554 — 29,554 Trademarks 159 — 159 159 — 159 $ 97,035 $ — $ 97,035 $ 97,032 $ — $ 97,032 Finite-lived intangible assets: Customer relationships $ 18,230 $ (10,777 ) $ 7,453 $ 18,229 $ (8,664 ) $ 9,565 Other intangible assets 405 (122 ) 283 409 (92 ) 317 $ 18,635 $ (10,899 ) $ 7,736 $ 18,638 $ (8,756 ) $ 9,882 Amortization expense related to customer relationships and other intangible assets for the years ended December 31, 2019 , 2018 and 2017 was $2.2 billion , $2.4 billion and $2.7 billion , respectively. The Company expects amortization expense on its finite-lived intangible assets will be as follows. 2020 $ 1,874 2021 1,599 2022 1,329 2023 1,072 2024 821 Thereafter 1,041 $ 7,736

Investments [Abstract]
Investments	Investments Investments consisted of the following as of December 31, 2019 and 2018 : December 31, 2019 2018 Equity-method investments $ 309 $ 454 Other investments 21 22 Total investments $ 330 $ 476 The Company’s equity-method investments consist of investments in companies that develop sports programming services, develop applications to improve the security, control and privacy of connected devices in homes and businesses for broadband network operators, distribute multi-video programs to national advertisers, provide programming on a video on demand, pay-per-view and subscription basis and develop and deploy cloud-based software video user interfaces. The Company's equity-method investments balances reflected in the table above includes differences between the acquisition date fair value of certain investments acquired and the underlying equity in the net assets of the investee, referred to as a basis difference. This basis difference is amortized as a component of equity earnings. The remaining unamortized basis difference was $203 million and $396 million as of December 31, 2019 and 2018 , respectively. The Company applies the equity method of accounting to these and other less significant equity-method investments, all of which are recorded in other noncurrent assets in the consolidated balance sheets as of December 31, 2019 and 2018 . For the years ended December 31, 2019 , 2018 and 2017 , net losses from equity-method investments were $137 million , $77 million and $18 million , respectively, which were recorded in other expense, net in the consolidated statements of operations. Net losses from equity-method investments for the years ended December 31, 2019 and 2018 included impairments on equity investments of approximately $121 million and $58 million , respectively. Real Estate Investments through Variable Interest Entities In July 2018, the Company's build-to-suit lease arrangement with a single-asset special purpose entity ("SPE") to build a new Charter headquarters in Stamford, Connecticut obtained all approvals and was made effective. The SPE obtained a first-lien mortgage note to finance the construction with fixed monthly payments through July 15, 2035 with a 5.612% coupon interest rate. All payments of the mortgage note are guaranteed by Charter. The initial term of the lease is 15 years commencing August 1, 2020, with no termination options. At the end of the lease term there is a mirrored put option for the SPE to sell the property to Charter and call option for Charter to purchase the property for a fixed purchase price. As the Company has determined the SPE is a VIE of which it became the primary beneficiary upon the effectiveness of the arrangement, the Company has consolidated the assets and liabilities of the SPE in its consolidated balance sheet as of December 31, 2019 and 2018 as follows. December 31, 2019 2018 Assets Current assets $ — $ 2 Restricted cash $ 66 $ 214 Property, plant and equipment $ 295 $ 130 Liabilities Current liabilities $ 11 $ — Other long-term liabilities $ 350 $ 346 Property, plant and equipment includes land, a parking garage and building construction costs, including the capitalization of qualifying interest. As of December 31, 2019 and 2018 , other long-term liabilities include $339 million and $342 million , respectively, in VIE's mortgage note liability and $11 million and $4 million , respectively, in liability-classified noncontrolling interest recorded at amortized cost with accretion towards settlement of the put/call option in the lease. The consolidated statement of cash flows for the year ended December 31, 2019 includes a decrease to restricted cash of $148 million primarily related to building construction costs. The consolidated statement of cash flows for the year ended December 31, 2018 includes an increase to restricted cash of $214 million as a result of activity in the VIE including borrowings of $342 million by the VIE on the mortgage note liability offset by distributions by the VIE to the noncontrolling interest of $107 million for the contributed land and parking garage and $21 million incurred by the VIE for building construction costs. In October 2017, the Company acquired a defaulted mortgage loan issued to a single-asset SPE. The consolidated statement of cash flows for the year ended December 31, 2017 includes $105 million related to the acquisition of the mortgage loan. As the Company has determined the SPE is a VIE of which it is the primary beneficiary, the Company has consolidated the assets and liabilities of the SPE in its consolidated balance sheet which are primarily comprised of the building securing the mortgage loan.

As of December 31, 2019 , there was no default under any of these indentures or credit facilities and each subsidiary met its applicable leverage ratio tests based on December 31, 2019 financial results. There can be no assurance that they will satisfy these tests at the time of the contemplated distribution. Distributions by Charter Operating for payment of principal on parent company (CCO Holdings) notes are further restricted by the covenants in its credit facilities. However, without regard to leverage, during any calendar year or any portion thereof during which the borrower is a flow-through entity for tax purposes, and so long as no event of default exists, the borrower may make distributions to the equity interests of the borrower in an amount sufficient to make permitted tax payments. In addition to the limitation on distributions under the various indentures, distributions by the Company’s subsidiaries may be limited by applicable law, including the Delaware Limited Liability Company Act, under which the Company’s subsidiaries may make distributions if they have “surplus” as defined in the act.

The timing and terms of any refinancing transactions will be subject to market conditions.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Noncontrolling interests represents consolidated subsidiaries of which the Company owns less than 100% . The Company is a holding company whose principal asset is a controlling equity interest in Charter Holdings, the indirect owner of the Company’s cable systems. Noncontrolling interests on the Company’s balance sheet primarily includes A/N’s equity interests in Charter Holdings, which is comprised of a common ownership interest and a convertible preferred ownership interest. As of December 31, 2019 , A/N held 17.9 million Charter Holdings common units which are exchangeable at any time into either Charter Class A common stock on a one-for-one basis, or, at Charter’s option, cash, based on the then current market price of Charter Class A common stock. Net income (loss) of Charter Holdings attributable to A/N’s common noncontrolling interest for financial reporting purposes is based on the weighted average effective common ownership interest of approximately 8% , 8% and 9% and was $173 million , $125 million and $69 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. Charter Holdings is required to make quarterly cash tax distributions (with annual true-ups) on a pro rata basis to its partners based on the partner with the highest proportionate cash tax requirement. To the extent such tax distributions would exceed Charter’s cash tax requirements, it may waive its entitlement to tax distributions and, instead, issue a non-pro rata "advance" to A/N, which will accrue interest at a money market rate and will reduce A/N’s exchange value into cash or Charter Class A common stock. Charter Holdings distributed $2 million to A/N as a pro rata tax distribution on its common units during the year ended December 31, 2019 and $3 million during each of the years ended December 31, 2018 and 2017 . The following table represents Charter Holdings' purchase of Charter Holdings common units from A/N pursuant to the Letter Agreement (see Note 20) and the effect on total shareholders' equity during the years ended December 31, 2019 , 2018 and 2017 . Year Ended December 31, 2019 2018 2017 Number of units purchased 2,276,906 2,125,190 4,798,367 Average price per unit $ 388.72 $ 308.90 $ 347.03 Amount of units purchased $ 885 $ 656 $ 1,665 Decrease in noncontrolling interest based on carrying value $ (565 ) $ (518 ) $ (1,187 ) Decrease in additional paid-in-capital, net of tax $ (240 ) $ (104 ) $ (295 ) Total shareholders' equity was also adjusted during the years ended December 31, 2019 , 2018 and 2017 due to changes in Charter Holdings' ownership as follows. Year Ended December 31, 2019 2018 2017 Decrease in noncontrolling interest $ (226 ) $ (72 ) $ (362 ) Increase in additional paid-in-capital, net of tax $ 170 $ 54 $ 223 The following table represents the exchange of Charter Holdings common units held by A/N for shares of Charter Class A common stock pursuant to the Letter Agreement (see Note 20) and the effect on total shareholders' equity during the year ended December 31, 2017 . The exchange of A/N common units resulted in a step-up in the tax-basis of the assets of Charter Holdings which is further discussed in Note 17. Year Ended December 31, 2017 Number of units exchanged 1,263,497 Amount of units exchanged $ 400 Decrease in noncontrolling interest based on carrying value $ (298 ) Increase in additional paid-in-capital, net of tax and TRA effects $ 265 As of December 31, 2019 , A/N also held 25 million Charter Holdings convertible preferred units with a face amount of $2.5 billion that pays a 6% annual preferred dividend. The 6% annual preferred dividend is paid quarterly in cash, if and when declared, provided that, if dividends are suspended at any time, the dividends will accrue until they are paid. Net income (loss) of Charter Holdings attributable to A/N's preferred noncontrolling interest for financial reporting purposes is based on the preferred dividend which was $150 million for each of the years ended December 31, 2019 , 2018 and 2017 . Each convertible preferred unit is convertible into either 0.37334 of a Charter Holdings common unit (if then held by A/N) or 0.37334 of a share of Charter Class A common stock (if then held by a third party), representing a conversion price of $267.85 per unit, based on a conversion feature as defined in the Limited Liability Company Agreement of Charter Holdings. After May 18, 2021, Charter may redeem the convertible preferred units if the price of Charter Class A common stock exceeds 130% of the conversion price, or $348.205

Accounting for Derivative Instruments and Hedging Activities [Abstract]
Accounting for Derivative Instruments and Hedging Activities	Accounting for Derivative Instruments and Hedging Activities The Company uses derivative instruments to manage foreign exchange risk on the Sterling Notes, and does not hold or issue derivative instruments for speculative trading purposes. Cross-currency derivative instruments are used to effectively convert £1.275 billion aggregate principal amount of fixed-rate British pound sterling denominated debt, including annual interest payments and the payment of principal at maturity, to fixed-rate U.S. dollar denominated debt. The cross-currency swaps have maturities of June 2031 and July 2042. The Company is required to post collateral on the cross-currency derivative instruments when the derivative contracts are in a liability position. In April 2019, the Company entered into a collateral holiday agreement for 60% of both the 2031 and 2042 cross-currency swaps, which eliminates the requirement to post collateral for three years , as well as a ten year collateral cap on the remaining 40% of the cross-currency swaps which limits the required collateral posting on that 40% of the cross-currency swaps to $150 million . The fair value of the Company's cross-currency derivatives included in other long-term liabilities on the Company's consolidated balance sheets was $224 million and $237 million as of December 31, 2019 and 2018 , respectively. The Company’s derivative instruments are not designated as hedges and are marked to fair value each period, with the impact recorded as a gain or loss on financial instruments, net in the consolidated statements of operations. While these derivative instruments are not designated as hedges for accounting purposes, management continues to believe such instruments are closely correlated with the respective debt, thus managing associated risk. The effect of financial instruments on the consolidated statements of operations is presented in the table below. Year Ended December 31, 2019 2018 2017 Gain (Loss) on Financial Instruments, Net: Change in fair value of cross-currency derivative instruments $ 13 $ (212 ) $ 226 Foreign currency remeasurement of Sterling Notes to U.S. dollars (67 ) 102 (157 ) $ (54 ) $ (110 ) $ 69

Fair Value Measurements [Abstract]
Fair Value Measurements	Fair Value Measurements Accounting guidance establishes a three-level hierarchy for disclosure of fair value measurements, based on the transparency of inputs to the valuation of an asset or liability as of the measurement date, as follows: • Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement. Financial Assets and Liabilities The Company has estimated the fair value of its financial instruments as of December 31, 2019 and 2018 using available market information or other appropriate valuation methodologies. Considerable judgment, however, is required in interpreting market data to develop the estimates of fair value. Accordingly, the estimates presented in the accompanying consolidated financial statements are not necessarily indicative of the amounts the Company would realize in a current market exchange. The carrying amounts of cash and cash equivalents, restricted cash, receivables, payables and other current assets and liabilities approximate fair value because of the short maturity of those instruments. Financial instruments accounted for at fair value on a recurring basis and classified within Level 2 of the valuation hierarchy include the Company's cross-currency derivative instruments and were valued at $224 million and $237 million as of December 31, 2019 and December 31, 2019 , respectively. The estimated fair value of the Company’s senior notes and debentures as of December 31, 2019 and 2018 is based on quoted market prices in active markets and is classified within Level 1 of the valuation hierarchy, while the estimated fair value of the Company’s credit facilities is based on quoted market prices in inactive markets and is classified within Level 2. The carrying amount of the consolidated variable interest entity's mortgage note liability approximates fair value. A summary of the carrying value and fair value of the Company’s debt at December 31, 2019 and 2018 is as follows: December 31, 2019 2018 Carrying Value Fair Value Carrying Value Fair Value Debt Senior notes and debentures $ 68,733 $ 74,938 $ 62,868 $ 61,087 Credit facilities $ 10,345 $ 10,448 $ 9,959 $ 9,608 Non-financial Assets and Liabilities

Stock Compensation Plans [Abstract]
Stock Compensation Plans	Stock Compensation Plans Charter’s stock incentive plan provides for grants of nonqualified stock options, incentive stock options, stock appreciation rights, dividend equivalent rights, performance units and performance shares, share awards, phantom stock, restricted stock units and restricted stock. Directors, officers and other employees of the Company and its subsidiaries, as well as others performing consulting services for the Company, are eligible for grants under the stock incentive plan. The stock incentive plan allows for the issuance of up to 16 million shares of Charter Class A common stock (or units convertible into Charter Class A common stock). Charter Stock options and restricted stock units generally cliff vest upon the three year anniversary of each grant. Certain stock options and restricted stock units vest based on achievement of stock price hurdles. Stock options generally expire ten years from the grant date and restricted stock units have no voting rights. Restricted stock generally vests one year from the date of grant. TWC restricted stock units that were converted into Charter restricted stock units in 2016 generally vest 50% on each of the third and fourth anniversary of the grant date. As of December 31, 2019 , total unrecognized compensation remaining to be recognized in future periods totaled $175 million for stock options, $0.9 million for restricted stock and $205 million for restricted stock units and the weighted average period over which they are expected to be recognized is 2 years for stock options, 4 months for restricted stock and 2 years for restricted stock units. The Company recorded $315 million , $285 million and $261 million of stock compensation expense for the years ended December 31, 2019 , 2018 and 2017 , respectively, which is included in operating costs and expenses.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Substantially all of the Company’s operations are held through Charter Holdings and its direct and indirect subsidiaries. Charter Holdings and the majority of its subsidiaries are generally limited liability companies that are not subject to income tax. However, certain of these limited liability companies are subject to state income tax. In addition, the subsidiaries that are corporations are subject to income tax. Generally, the taxable income, gains, losses, deductions and credits of Charter Holdings are passed through to its members, Charter and A/N. Charter is responsible for its share of taxable income or loss of Charter Holdings allocated to it in accordance with the Charter Holdings Limited Liability Company Agreement ("LLC Agreement") and partnership tax rules and regulations. As a result, Charter's primary deferred tax component recorded in the consolidated balance sheets relates to its excess financial reporting outside basis, excluding amounts attributable to nondeductible goodwill, over Charter's tax basis in the investment in Charter Holdings. Charter Holdings, the indirect owner of the Company’s cable systems, generally allocates its taxable income, gains, losses, deductions and credits proportionately according to the members’ respective ownership interests, except for special allocations required under Section 704(c) of the Internal Revenue Code and the Treasury Regulations (“Section 704(c)”). Pursuant to Section 704(c) and the LLC Agreement, each item of income, gain, loss and deduction with respect to any property contributed to the capital of the partnership shall, solely for tax purposes, be allocated among the members so as to take into account any variation between the adjusted basis of such property to the partnership for U.S. federal income tax purposes and its initial gross asset value using the “traditional method” as described in the Treasury Regulations. Income Tax Benefit (Expense) For the years ended December 31, 2019 , 2018 , and 2017 , the Company recorded deferred income tax benefit (expense) as shown below. The tax provision in future periods will vary based on current and future temporary differences, as well as future operating results. Year Ended December 31, 2019 2018 2017 Current expense: Federal income taxes $ (6 ) $ (23 ) $ (4 ) State income taxes (113 ) (47 ) (25 ) Current income tax expense (119 ) (70 ) (29 ) Deferred benefit (expense): Federal income taxes (358 ) (204 ) 9,082 State income taxes 38 94 34 Deferred income tax benefit (expense) (320 ) (110 ) 9,116 Income tax benefit (expense) $ (439 ) $ (180 ) $ 9,087 Income tax benefit for the year ended December 31, 2017 was recognized primarily as a result of the enactment of Tax Reform in December 2017. Among other things, the primary provisions of Tax Reform impacting the Company are the reductions to the U.S. corporate income tax rate from 35% to 21% and temporary 100% bonus depreciation for certain assets. The change in tax law required the Company to remeasure existing net deferred tax liabilities using the lower rate in the period of enactment resulting in an income tax benefit of approximately $9.3 billion to reflect these changes in the year ended December 31, 2017. The Company’s effective tax rate differs from that derived by applying the applicable federal income tax rate of 21% for the years ended December 31, 2019 and 2018 and 35% for the year ended December 31, 2017 , respectively, as follows: Year Ended December 31, 2019 2018 2017 Statutory federal income taxes $ (510 ) $ (354 ) $ (360 ) Statutory state income taxes, net (57 ) (54 ) (34 ) Change in uncertain tax positions (64 ) (24 ) 3 Nondeductible expenses (24 ) (25 ) (21 ) Net income attributable to noncontrolling interest 80 68 84 Excess stock compensation 63 34 88 Federal tax credits 46 77 21 Tax rate changes 15 107 9,293 Other 12 (9 ) 13 Income tax benefit (expense) $ (439 ) $ (180 ) $ 9,087 Deferred Tax Assets (Liabilities) The tax effects of these temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2019 and 2018 are presented below. December 31, 2019 2018 Deferred tax assets: Loss carryforwards $ 1,839 $ 2,453 Accrued and other 664 578 Total gross deferred tax assets 2,503 3,031 Less: valuation allowance (46 ) (89 ) Deferred tax assets $ 2,457 $ 2,942 Deferred tax liabilities: Investment in partnership $ (20,159 ) $ (20,319 ) Accrued and other (9 ) (12 ) Deferred tax liabilities (20,168 ) (20,331 ) Net deferred tax liabilities $ (17,711 ) $ (17,389 ) The deferred tax liabilities on the investment in partnership above includes approximately $55 million net deferred tax liabilities and $3 million net deferred tax assets relating to certain indirect subsidiaries that file separate state income tax returns at December 31, 2019 and 2018 , respectively. Valuation Allowance In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. In evaluating the need for a valuation allowance, management takes into account various factors, including the expected level of future taxable income, available tax planning strategies and reversals of existing taxable temporary differences. As of December 31, 2019 , approximately $9 million of the valuation allowance is associated with federal capital loss carryforwards and $37 million is associated with state tax loss carryforwards and other miscellaneous deferred tax assets. As of December 31, 2018 , approximately $39 million of the valuation allowance is associated with federal tax net operating loss carryforwards acquired in acquisitions and approximately $50 million is associated with state tax loss carryforwards and tax credits. Net Operating Loss Carryforwards As of December 31, 2019 , Charter had approximately $7.5 billion of federal tax net operating loss carryforwards resulting in a gross deferred tax asset of approximately $1.6 billion . Federal tax net operating loss carryforwards expire in the years 2020 through 2035. These losses resulted from the operations of Charter Communications Holdings Company, LLC ("Charter Holdco") and its subsidiaries. In addition, as of December 31, 2019 , Charter had state tax net operating loss carryforwards, resulting in a gross deferred tax asset (net of federal tax benefit) of approximately $257 million . State tax net operating loss carryforwards generally expire in the years 2020 through 2039. Upon closing of the merger with TWC in 2016, Charter experienced a third “ownership change” as defined in Section 382 of the Internal Revenue Code; resulting in a third set of limitations on Charter’s use of its existing federal and state net operating losses, capital losses, and tax credit carryforwards. Both the first ownership change limitations that applied as a result of Charter’s emergence from bankruptcy in 2009 and second ownership change limitations that applied as a result of Liberty Media Corporation’s purchase in 2013 of a 27% beneficial interest in Charter will also continue to apply. After December 31, 2019 , $905 million of Charter's federal tax loss carryforwards are subject to Section 382 and other restrictions. Pursuant to these restrictions, Charter estimates that approximately $226 million annually over each of the next four years of federal tax loss carryforwards should become unrestricted and available for Charter’s use. Since the limitation amounts accumulate for future use to the extent they are not utilized in any given year, Charter believes its loss carryforwards should become fully available to offset future taxable income. Charter’s state loss carryforwards are subject to similar, but varying, limitations on their future use. If Charter was to experience another “ownership change” in the future, its ability to use its loss carryforwards could be subject to further limitations. Tax Receivable Agreement Under the LLC Agreement, A/N has rights to: (1) convert at any time some or all of its preferred units in Charter Holdings for common units in Charter Holdings, and (2) exchange at any time some or all of its common units in Charter Holdings for Charter’s Class A common stock or cash, at Charter’s option. Pursuant to a TRA between Charter and A/N, Charter must pay to A/N 50% of the tax benefit when realized by Charter from the step-up in tax basis resulting from any future exchange or sale of the preferred and common units. Charter did not record a liability for this obligation as of the acquisition date since the tax benefit is dependent on uncertain future events that are outside of Charter’s control, such as the timing of a conversion or exchange. A future exchange or sale is not based on a fixed and determinable date and the exchange or sale is not certain to occur. If all of A/N's partnership units were to be exchanged or sold in the future, the undiscounted value of the obligation is currently estimated to be in the range of zero to $3 billion depending on measurement of the tax step-up in the future and Charter’s ability to realize the tax benefit in the periods following the exchange or sale. Factors impacting these calculations include, but are not limited to, the fair value of the equity at the time of the exchange and the effective tax rates when the benefits are realized. In connection with the Letter Agreement between Charter and A/N (see Note 20) whereby 1.3 million Charter Holdings common units held by A/N during the year ended December 31, 2017 were exchanged for shares of Charter Class A common stock for an aggregate purchase price of $400 million , an immediate step-up of $487 million in the tax basis of the assets of Charter Holdings occurred. As it relates to the exchange and tax step-up, a net deferred tax asset of approximately $85 million was recorded and a resulting TRA liability owed to A/N of $118 million which, as a transaction with a shareholder, was recorded directly to additional paid in capital, net of tax during the year ended December 31, 2017 . The TRA liability is recorded on an iterative, undiscounted basis. During the year ended December 31, 2017, the TRA liability was remeasured as a result of the enactment of Tax Reform resulting in a $101 million benefit recorded to other operating expenses, net. See Note 15. Following such remeasurement, the TRA liability of $150 million and $151 million is reflected in other long-term liabilities on the consolidated balance sheets as of December 31, 2019 and 2018 , respectively. Uncertain Tax Positions The net amount of the unrecognized tax benefits recorded as of December 31, 2019 that could impact the effective tax rate is $242 million . The Company has determined that it is reasonably possible that its existing reserve for uncertain tax positions as of December 31, 2019 could decrease by approximately $31 million during the year ended December 31, 2020 related to various ongoing audits, settlement discussions and expiration of statute of limitations with various state and local agencies; however, various events could cause the Company’s current expectations to change in the future. These uncertain tax positions, if ever recognized in the financial statements, would be recorded in the consolidated statements of operations as part of the income tax provision. A reconciliation of the beginning and ending amount of unrecognized tax benefits, exclusive of interest and penalties, included in other long-term liabilities on the accompanying consolidated balance sheets of the Company is as follows: BALANCE, December 31, 2017 $ 164 Additions on prior year tax positions 7 Additions on current year tax positions 25 Reductions on settlements and expirations with taxing authorities (16 ) BALANCE, December 31, 2018 $ 180 Additions on prior year tax positions 15 Additions on current year tax positions 44 Reductions on settlements and expirations with taxing authorities (9 ) BALANCE, December 31, 2019 $ 230 The Company recognizes interest and penalties accrued on uncertain income tax positions as part of the income tax provision. Interest and penalties included in other long-term liabilities on the accompanying consolidated balance sheets of the Company were $56 million and $45 million as of December 31, 2019 and 2018 , respectively. No tax years for Charter are currently under examination by the Internal Revenue Service ("IRS") for income tax purposes. Charter's 2016 through 2019 tax years remain open for examination and assessment. Charter’s short period return dated May 17, 2016 (prior to the TWC and Bright House Networks, LLC transactions) remain subject to examination and assessment. Years prior to 2016 remain open solely for purposes of examination of Charter’s loss and credit carryforwards. The IRS is currently examining Charter Holdings’ income tax return for 2016. Charter Holdings’ 2017 through 2019 tax years remain open for examination and assessment. The IRS is currently examining TWC’s income tax returns for 2011 through 2014. TWC’s tax year 2015 remains subject to examination and assessment. Prior to TWC’s separation from Time Warner Inc. (“Time Warner”) in March 2009, TWC was included in the consolidated U.S. federal and certain state income tax returns of Time Warner. The IRS has examined Time Warner’s 2008 through 2010 income tax returns and the results are under appeal. The Company does not anticipate that these examinations will have a material impact on the Company’s consolidated financial position or results of operations. In addition, the Company is also subject to ongoing examinations of the Company’s tax returns by state and local tax authorities for various periods. Activity related to these state and local examinations did not have a material impact on the Company’s consolidated financial position or results of operations during the year ended December 31, 2019 , nor does the Company anticipate a material impact in the future.

Earnings (Loss) Per Share [Abstract]
Earnings per Share	Earnings Per Share Basic earnings per common share is computed by dividing net income attributable to Charter shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per common share considers the impact of potentially dilutive securities using the treasury stock and if-converted methods and is based on the weighted average number of shares used for the basic earnings per share calculation, adjusted for the dilutive effect of stock options, restricted stock, restricted stock units, equity awards with market conditions and Charter Holdings convertible preferred units and common units. Charter Holdings common and convertible preferred units of 29 million and 31 million for the years ended December 31, 2019 and 2018 were not included in the computation of diluted earnings per share as their effect would have been antidilutive. The following is the computation of diluted earnings per common share for the years presented. Year Ended December 31, 2019 2018 2017 Numerator: Net income attributable to Charter shareholders $ 1,668 $ 1,230 $ 9,895 Effect of dilutive securities: Charter Holdings common units — — 69 Charter Holdings convertible preferred units — — 150 Net income attributable to Charter shareholders after assumed conversions $ 1,668 $ 1,230 $ 10,114 Denominator: Weighted average common shares outstanding, basic 219,506,735 232,356,665 256,720,715 Effect of dilutive securities: Assumed exercise or issuance of shares relating to stock plans 4,279,645 3,168,561 4,012,145 Weighted average Charter Holdings common units — — 26,637,596 Weighted average Charter Holdings convertible preferred units — — 9,333,500 Weighted average common shares outstanding, diluted 223,786,380 235,525,226 296,703,956 Basic earnings per common share attributable to Charter shareholders $ 7.60 $ 5.29 $ 38.55 Diluted earnings per common share attributable to Charter shareholders $ 7.45 $ 5.22 $ 34.09

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions The following sets forth certain transactions in which the Company and the directors, executive officers, and affiliates of the Company are involved or, in the case of the management arrangements, subsidiaries that are debt issuers that pay certain of their parent companies for services. Charter is a party to management arrangements with one of its subsidiaries, Spectrum Management Holding Company, LLC ("Spectrum Management") and certain of their subsidiaries. Under these agreements, Charter, Spectrum Management and Charter Holdco provide management services for the cable systems owned or operated by their subsidiaries. Costs associated with providing these services are charged directly to the Company’s operating subsidiaries. All other costs incurred on behalf of Charter’s operating subsidiaries are considered a part of the management fee. These costs are recorded as a component of operating costs and expenses, in the accompanying consolidated financial statements. The management fee charged to the Company’s operating subsidiaries approximated the expenses incurred by Spectrum Management, Charter Holdco and Charter on behalf of the Company’s operating subsidiaries in 2019 , 2018 and 2017 . Liberty Broadband and A/N Under the terms of the Amended and Restated Stockholders Agreement with Liberty Broadband, A/N and Legacy Charter, dated May 23, 2015, (the “Stockholders Agreement”), the number of Charter’s directors is fixed at 13, and includes its CEO. Two designees selected by A/N are members of the board of directors of Charter and three designees selected by Liberty Broadband are members of the board of directors of Charter. The remaining eight directors are not affiliated with either A/N or Liberty Broadband. Each of A/N and Liberty Broadband is entitled to nominate at least one director to each of the committees of Charter's board of directors, subject to applicable stock exchange listing rules and certain specified voting or equity ownership thresholds for each of A/N and Liberty Broadband, and provided that the Nominating and Corporate Governance Committee and the Compensation and Benefit Committee each have at least a majority of directors independent from A/N, Liberty Broadband and Charter (referred to as the “unaffiliated directors”). Each of the Nominating and Corporate Governance Committee and the Compensation and Benefits Committee is currently comprised of three unaffiliated directors and one designee of each of A/N and Liberty Broadband. A/N and Liberty Broadband also have certain other committee designation and other governance rights. Mr. Thomas Rutledge, the Company’s CEO, is the chairman of the board of Charter. In December 2017, Charter and A/N entered into an amendment to the letter agreement (the “Letter Agreement”) that requires A/N to sell to Charter or to Charter Holdings, on a monthly basis, a number of shares of Charter Class A common stock or Charter Holdings common units that represents a pro rata participation by A/N and its affiliates in any repurchases of shares of Charter Class A common stock from persons other than A/N effected by Charter during the immediately preceding calendar month, at a purchase price equal to the average price paid by Charter for the shares repurchased from persons other than A/N during such immediately preceding calendar month. A/N and Charter both have the right to terminate or suspend the pro rata repurchase arrangement on a prospective basis. Pursuant to the TRA between Charter and A/N, Charter must pay to A/N 50% of the tax benefit when realized by Charter from the step-up in tax basis resulting from any future exchange or sale of the preferred and common units. See Note 17 for more information. The Company is aware that Dr. John Malone, a director emeritus of Charter and Chairman of the board of directors and holder of 49.0% of voting interest in Liberty Broadband, may be deemed to have a 39.9% voting interest in Qurate Retail, Inc. ("Qurate") and is on the board of directors of Qurate. Qurate wholly owns HSN, Inc. (“HSN”) and QVC, Inc. (“QVC”). The Company has programming relationships with HSN and QVC. For the years ended December 31, 2019 , 2018 and 2017 , the Company recorded revenue in aggregate of approximately $50 million , $73 million and $77 million , respectively, from HSN and QVC as part of channel carriage fees and revenue sharing arrangements for home shopping sales made to customers in the Company’s footprint. Dr. Malone and Mr. Steven Miron, a member of Charter’s board of directors, also serve on the board of directors of Discovery Communications, Inc., (“Discovery”). The Company is aware that Dr. Malone owns 1.2% of the series A common stock, 93.6% of the series B common stock and 2.6% of the series C common stock of Discovery and has a 28.2% voting interest in Discovery for the election of directors. The Company is aware that Advance/Newhouse Programming Partnership (“A/N PP”), an affiliate of A/N and in which Mr. Miron is the CEO, owns 100% of the Series A-1 preferred stock of Discovery and 100% of the Series C-1 preferred stock of Discovery and has a 24.1% voting interest for matters other than the election of directors. A/N PP also has the right to appoint three directors out of a total of twelve directors to Discovery’s board. The Company purchases programming from Discovery pursuant to agreements entered into prior to Dr. Malone and Mr. Miron joining Charter’s board of directors. Based on publicly available information, the Company does not believe that Discovery would currently be considered a related party. The amount paid to Discovery represents less than 3% of total operating costs and expenses for the years ended December 31, 2019 , 2018 and 2017 . Equity Investments The Company has agreements with certain equity investees (see Note 6) pursuant to which the Company has made or received related party transaction payments. The Company recorded payments to equity investees totaling $314 million , $361 million and $317 million during the years ended December 31, 2019 , 2018 and 2017

Commitments and Contingencies	Commitments and Contingencies Commitments The following table summarizes the Company’s payment obligations as of December 31, 2019 for its contractual obligations. Total 2020 2021 2022 2023 2024 Thereafter Programming Minimum Commitments (a) $ 276 $ 216 $ 37 $ 12 $ 11 $ — $ — Other (b) 12,658 2,536 2,598 436 366 526 6,196 $ 12,934 $ 2,752 $ 2,635 $ 448 $ 377 $ 526 $ 6,196 (a) The Company pays programming fees under multi-year contracts ranging from three to ten years , typically based on a flat fee per customer, which may be fixed for the term, or may in some cases escalate over the term. Programming costs included in the statement of operations were 11.3 billion , 11.1 billion and 10.6 billion for the years ended December 31, 2019 , 2018 and 2017 respectively. Certain of the Company’s programming agreements are based on a flat fee per month or have guaranteed minimum payments. The table sets forth the aggregate guaranteed minimum commitments under the Company’s programming contracts. (b) “Other” represents other guaranteed minimum commitments, including rights negotiated directly with content owners for distribution on company-owned channels or networks, commitments related to our role as an advertising and distribution sales agent for third party-owned channels or networks, commitments to our customer premise equipment and device vendors and contractual obligations related to third-party network augmentation. The following items are not included in the contractual obligation table due to various factors discussed below. However, the Company incurs these costs as part of its operations: • The Company rents utility poles used in its operations. Generally, pole rentals are cancelable on short notice, but the Company anticipates that such rentals will recur. Rent expense incurred for pole rental attachments for the years ended December 31, 2019 , 2018 and 2017 was $180 million , $171 million and $167 million , respectively. • The Company pays franchise fees under multi-year franchise agreements based on a percentage of revenues generated from video service per year. The Company also pays other franchise related costs, such as public education grants, under multi-year agreements. Franchise fees and other franchise-related costs included in the accompanying statement of operations were $750 million , $747 million and $705 million for the years ended December 31, 2019 , 2018 and 2017 respectively. • The Company has $363 million in letters of credit, of which $36 million is secured under the Charter Operating credit facility, primarily to its various casualty carriers as collateral for reimbursement of workers' compensation, auto liability and general liability claims. • Minimum pension funding requirements have not been presented in the table above as such amounts have not been determined beyond 2019 . The Company made no cash contributions to the qualified pension plans in 2019 ; however, the Company is permitted to make discretionary cash contributions to the qualified pension plans in 2020 . For the nonqualified pension plan, the Company contributed $4 million during 2019 and will continue to make contributions in 2020 to the extent benefits are paid. Legal Proceedings In August 2015, a purported stockholder of Charter, Matthew Sciabacucchi, filed a lawsuit in the Delaware Court of Chancery, on behalf of a putative class of Charter stockholders, challenging the transactions involving Charter, TWC, A/N, and Liberty Broadband announced by Charter on May 26, 2015. The lawsuit, which named as defendants Charter and its board of directors, alleged that the transactions resulted from breaches of fiduciary duty by Charter’s directors and that Liberty Broadband improperly benefited from the challenged transactions at the expense of other Charter stockholders. The lawsuit has proceeded to the discovery phase. Charter denies any liability, believes that it has substantial defenses, and is vigorously defending this lawsuit. Although Charter is unable to predict the outcome of this lawsuit, it does not expect the outcome will have a material effect on its operations, financial condition or cash flows. The California Attorney General and the Alameda County, California District Attorney are investigating whether certain of Charter’s waste disposal policies, procedures and practices are in violation of the California Business and Professions Code and the California Health and Safety Code. That investigation was commenced in January 2014. A similar investigation involving TWC was initiated in February 2012. Charter is cooperating with these investigations. While the Company is unable to predict the outcome of these investigations, it does not expect that the outcome will have a material effect on its operations, financial condition, or cash flows. On December 19, 2011, Sprint Communications Company L.P. (“Sprint”) filed a complaint in the U.S. District Court for the District of Kansas alleging that TWC infringed certain U.S. patents purportedly relating to Voice over Internet Protocol (“VoIP”) services. At the trial, the jury returned a verdict of $140 million against TWC and further concluded that TWC had willfully infringed Sprint’s patents. The court subsequently declined to enhance the damage award as a result of the purported willful infringement and awarded Sprint an additional $6 million , representing pre-judgment interest on the damages award. The Company appealed the case to the United States Court of Appeals for the Federal Circuit where the Company lost the appeal. The Company filed a petition for writ of certiorari with the United States Supreme Court which was denied on November 4, 2019. The Company has now paid the verdict, interest and costs in full. The Company continues to pursue indemnity from one of its vendors and has brought a patent suit against Sprint (TC Tech, LLC v. Sprint) in the U.S. District Court for the District of Delaware implicating Sprint's LTE technology. The ultimate outcomes of the pursuit of indemnity against the Company’s vendor and the TC Tech litigation cannot be predicted. The Company does not expect the outcome of its indemnity claim nor the outcome of the TC Tech litigation will have a material adverse effect on its operations or financial condition. Sprint filed a second suit against Charter and Bright House Networks, LLC on December 2, 2017 in the United States District Court for the District of Delaware. This suit alleges infringement of 15 patents related to the Company's provision of Voice over Internet Protocol (“VoIP”) services (ten of which were asserted against Legacy TWC in the matter described above). Charter is vigorously defending this case. While the Company is unable to predict the outcome of this Sprint suit, it does not expect that this litigation will have a material effect on its operations, financial condition, or cash flows. Sprint filed a third suit against Charter on May 17, 2018 in the United States District Court for the Eastern District of Virginia. This suit alleges infringement of three patents related to the Company's video on demand services. The Company is vigorously defending this case. The court transferred this case to the United States District Court for the District of Delaware on December 20, 2018 pursuant to an agreement between the parties. While the Company is unable to predict the outcome of this litigation, it does not expect that this litigation will have a material effect on its operations, financial condition, or cash flows. In addition to the Sprint litigation described above, the Company is a defendant or co-defendant in several additional lawsuits involving alleged infringement of various intellectual property relating to various aspects of its businesses. Other industry participants are also defendants in certain of these cases. In the event that a court ultimately determines that the Company infringes on any intellectual property, the Company may be subject to substantial damages and/or an injunction that could require the Company or its vendors to modify certain products and services the Company offers to its subscribers, as well as negotiate royalty or license agreements with respect to the intellectual property at issue. While the Company believes the lawsuits are without merit and intends to defend the actions vigorously, no assurance can be given that any adverse outcome would not be material to the Company’s consolidated financial condition, results of operations, or liquidity. The Company cannot predict the outcome of any such claims nor can it reasonably estimate a range of possible loss. The Company is party to other lawsuits, claims and regulatory inquiries that arise in the ordinary course of conducting its business. The ultimate outcome of these other legal matters pending against the Company cannot be predicted, and although such lawsuits and claims are not expected individually to have a material adverse effect on the Company’s consolidated financial condition, results of operations or liquidity, such lawsuits could have, in the aggregate, a material adverse effect on the Company’s consolidated financial condition, results of operations or liquidity. Whether or not the Company ultimately prevails in any particular lawsuit or claim, litigation can be time consuming and costly and injure the Company’s reputation.

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]
Employee Benefit Plans	Employee Benefit Plans Pension Plans The Company sponsors three qualified defined benefit pension plans and one nonqualified defined benefit pension plan that provide pension benefits to a majority of employees who were employed by TWC before the merger with TWC. Changes in the projected benefit obligation, fair value of plan assets and funded status of the pension plans from January 1 through December 31 are presented below: 2019 2018 Projected benefit obligation at beginning of year $ 3,041 $ 3,569 Interest cost 129 128 Actuarial (gain) loss 499 (438 ) Settlement (257 ) (169 ) Benefits paid (51 ) (49 ) Projected benefit obligation at end of year (a) $ 3,361 $ 3,041 Accumulated benefit obligation at end of year (a) $ 3,361 $ 3,041 Fair value of plan assets at beginning of year $ 2,943 $ 3,273 Actual return on plan assets 559 (118 ) Employer contributions 4 6 Settlement (257 ) (169 ) Benefits paid (51 ) (49 ) Fair value of plan assets at end of year (b) $ 3,198 $ 2,943 Funded status $ (163 ) $ (98 ) (a) As of December 31, 2019 and 2018, qualified pension plans represented $3.3 billion and $3.0 billion , respectively, of both the projected benefit obligation and accumulated benefit obligation while the Company’s nonqualified pension plan represented $35 million and $34 million , respectively. (b) The fair value of plan assets consists entirely of the Company’s qualified pension plans. Pretax amounts recognized in the consolidated balance sheet as of December 31, 2019 and 2018 consisted of the following: December 31, 2019 2018 Noncurrent asset $ 1 $ 1 Current liability (4 ) (4 ) Long-term liability (160 ) (95 ) Net amounts recognized in consolidated balance sheet $ (163 ) $ (98 ) The components of net periodic benefit (cost) for the years ended December 31, 2019 , 2018 and 2017 consisted of the following: Year Ended December 31, 2019 2018 2017 Interest cost $ (129 ) $ (128 ) $ (133 ) Expected return on plan assets 164 198 189 Remeasurement gain (loss) (104 ) 122 (55 ) Net periodic pension benefit (cost) $ (69 ) $ 192 $ 1 The remeasurement gains (losses) recorded during the years ended December 31, 2019, 2018 and 2017 were primarily driven by changes in the discount rate as well as gains or losses to record pension assets to fair value. The remeasurement loss recorded during the year ended December 31, 2017 was also impacted by the adoption of the revised lump sum conversion mortality tables published by the IRS effective January 1, 2018. The discount rates used to determine benefit obligations as of December 31, 2019 and 2018 were 3.48% and 4.37% , respectively. The Company utilized the RP 2015/MP2015 mortality tables published by the Society of Actuaries to measure the benefit obligations as of December 31, 2019 and 2018 . Weighted average assumptions used to determine net periodic benefit costs consisted of the following: Year ended December 31, 2019 2018 2017 Expected long-term rate of return on plan assets 5.75 % 5.75 % 6.50 % Discount rate 4.37 % 4.24 % 3.88 % In developing the expected long-term rate of return on plan assets, the Company considered the pension portfolio’s composition, past average rate of earnings and the Company’s future asset allocation targets. The weighted average expected long-term rate of return on plan assets and discount rate used to determine net periodic pension benefit for the year ended December 31, 2020 are expected to be 5.00% and 3.48% , respectively. The Company determined the discount rates used to determine benefit obligations and net periodic pension benefit based on the yield of a large population of high quality corporate bonds with cash flows sufficient in timing and amount to settle projected future defined benefit payments. Pension Plan Assets The assets of the qualified pension plans are held in a master trust in which the qualified pension plans are the only participating plans (the “Master Trust”). The investment policy for the qualified pension plans is to manage the assets of the Master Trust with the objective to provide for pension liabilities to be met, maintaining retirement income security for the participants of the plans and their beneficiaries. The investment portfolio is a mix of pooled funds invested in fixed income securities, equity securities and certain alternative investments with the objective of matching plan liability performance, diversifying risk and achieving a target investment return. Pension assets are managed in a balanced portfolio comprised of two major components: a return-seeking portion and a liability-matching portion. The Company uses an investment strategy designed to increase the fixed income allocation as the funded status of the qualified pension plans improves. As the qualified pension plans reach set funded status milestones, the assets will be rebalanced to shift more assets from equity to fixed income. Based on the progress with this strategy, the target investment allocation for pension fund assets is permitted to vary within specified ranges subject to Investment Committee approval for return-seeking securities and liability-matching securities. The target and actual investment allocation of the qualified pension plans by asset category consisted of the following: December 31, 2019 December 31, 2018 Target Allocation Actual Allocation Target Allocation Actual Allocation Return-seeking securities 60.0 % 56.2 % 60.0 % 54.6 % Liability-matching securities 40.0 % 43.7 % 40.0 % 45.1 % Other investments — % 0.1 % — % 0.3 % The following tables set forth the investment assets of the qualified pension plans by level within the fair value hierarchy as of December 31, 2019 and 2018 : December 31, 2019 December 31, 2018 Fair Value Level 1 Level 2 Fair Value Level 1 Level 2 Cash $ 4 $ 4 $ — $ 4 $ 4 $ — Commingled bond funds (a) 1,335 — 1,335 1,270 — 1,270 Commingled equity funds (a) 1,135 — 1,135 952 — 952 Collective trust funds (b) 139 — 139 113 — 113 Total investment assets 2,613 $ 4 $ 2,609 2,339 $ 4 $ 2,335 Accrued investment income and other receivables 1 11 Investments measured at net asset value (c) 584 593 Fair value of plan assets $ 3,198 $ 2,943 (a) Commingled funds include bond funds with corporate and U.S. treasury debt securities and equity funds with global equity index, infrastructure and real estate securities that have a readily determinable fair value and are valued using the net assets provided by the administrator of the fund. The value of each fund is based on the fair value of underlying securities in the portfolio, which represents the amount that the fund might reasonably expect to receive for the securities upon a sale, less liabilities, and then divided by the number of units outstanding. Equity securities within the funds are valued using observable inputs on either a daily or weekly basis and the resulting per share value serves as a basis for current redemption value. Debt securities within the funds are valued based on observable prices from the new issue market, benchmark quotes, secondary trading and dealer quotes. (b) Collective trust funds consist of short-term investment strategies comprised of instruments issued or fully guaranteed by the U.S. government and/or its agencies and multi-strategy funds, which are valued using the net assets provided by the administrator of the fund. The value of each fund is based on the readily determinable fair value of the underlying assets owned by the fund, less liabilities, and then divided by the number of units outstanding. (c) As a practical expedient, certain investment classes which hold securities that are not readily available for redemption and are measured at fair value using the net asset value ("NAV") per share (or its equivalent) have not been classified in the fair value hierarchy. Investments Measured at Net Asset Value per Share Practical Expedient The following table summarizes the investment classes for which fair value is measured using the NAV per share (or its equivalent) practical expedient as of December 31, 2019 and 2018. These investment classes are not readily available for redemption. The NAV of each fund is based on the fair value of underlying assets in the portfolio. Certain investments report NAV per share on a month or quarter lag. There are no material unfunded commitments with respect to these investment classes. Fair Value December 31, Redemption Frequency (if currently eligible) Redemption Notice Period 2019 2018 Alternative funds (a) $ 271 $ 301 weekly, monthly, quarterly 1-180 days Fixed income funds (b) 177 164 daily, monthly 10-40 days Real estate funds (c) 136 128 quarterly 45-90 days Investments measured at NAV $ 584 $ 593 (a) The alternative fund investment class includes funds with various securities selected to provide complimentary sources of return with our equity and bond portfolios that better manage risk. The Company’s alternative fund investments include holdings such as public equities, exchange traded derivatives, and corporate bonds, among others. A portion of the alternative funds cannot be redeemed until the one year anniversary of the purchase date. (b) Fixed income funds invest in residential and commercial mortgages, as well as global sovereign securities. (c) Real estate funds are not publicly traded and invest primarily in unlisted direct core real estate, including super-regional malls, shopping centers, and commercial real estate (e.g. education, healthcare and storage). Pension Plan Contributions The Company made no cash contributions to the qualified pension plans during the years ended December 31, 2019 , 2018 and 2017 ; however, the Company may make discretionary cash contributions to the qualified pension plans in the future. Such contributions will be dependent on a variety of factors, including current and expected interest rates, asset performance, the funded status of the qualified pension plans and management’s judgment. For the nonqualified unfunded pension plan, the Company will continue to make contributions during 2020 to the extent benefits are paid. Benefit payments for the pension plans are expected to be $183 million in 2020 , $186 million in 2021 , $188 million in 2022 , $190 million in 2023 , $190 million in 2024 and $929 million in 2025 to 2029. Multiemployer Plans The Company contributes to multiemployer plans under the terms of collective-bargaining agreements that cover its union-represented employees. Such multiemployer plans provide medical, pension and retirement savings benefits to active employees and retirees. The Company made contributions to multiemployer plans of $9 million , $9 million and $18 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. As of December 31, 2019 and 2018 , other long-term liabilities includes approximately $101 million and $104 million , respectively, related to the Company's withdrawal from a multiemployer pension plan. Defined Contribution Benefit Plans The Company’s employees may participate in the Charter Communications, Inc. 401(k) Savings Plan (the “401(k) Plan”). Employees that qualify for participation can contribute up to 50% of their salary, on a pre-tax basis, subject to a maximum contribution limit as determined by the Internal Revenue Service. The Company’s matching contribution is discretionary and is equal to 100% of the amount of the salary reduction the participant elects to defer (up to 6% of the participant’s eligible compensation), excluding any catch-up contributions and is paid by the Company on a per pay period basis. The Company made contributions to the 401(k) plan totaling $303 million , $290 million and $274 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. For employees who are not eligible to participate in the Company’s long-term incentive plan and who are not covered by a collective bargaining agreement, the Company offers a contribution to the Retirement Accumulation Plan ("RAP"), equal to 3% of eligible pay. The Company made contributions to the RAP totaling $152 million , $151 million and $139 million for the years ended December 31, 2019 , 2018 and 2017 , respectively.

Accounting Standards Adopted January 1, 2019 ASU No. 2016-02, Leases (“ASU 2016-02”) In February 2016, the FASB issued ASU 2016-02 which requires lessees to recognize almost all leases on their balance sheet as a lease asset and a lease liability. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification is based on criteria largely similar to the criteria applied under legacy lease accounting, but without explicit bright lines. The Company adopted ASU 2016-02 using the modified retrospective approach with a cumulative-effect adjustment recorded at the beginning of the period of adoption (January 1, 2019). Therefore, the Company recognized and measured operating leases on the consolidated balance sheet without revising comparative period information or disclosure. At transition, the Company elected the package of practical expedients permitted under the transition guidance within the standard, which eliminates the reassessment of past leases, classification and initial direct costs. The Company did not elect to use hindsight to reassess lease terms or impairment at the adoption date. The Company elected the land easements practical expedient which allows the Company not to retrospectively treat land easements as leases; however, must apply lease accounting prospectively to land easements if they meet the definition of a lease. The Company implemented internal controls and key system functionality to enable the preparation of financial information on adoption. The new standard resulted in the recording of leased assets and lease liabilities for the Company’s operating leases of approximately $1.1 billion and $1.2 billion , respectively, as of January 1, 2019. The difference between the leased assets and lease liabilities primarily represents the prior year end deferred rent liabilities balance, resulting from historical straight-lining of operating leases, which was effectively reclassified upon adoption to reduce the measurement of the leased assets. The adoption of the standard did not have an impact on the Company’s shareholders equity, results from operations and cash flows. The adoption of the new standard resulted in additional interim and annual lease disclosures. See Note 8. ASU No. 2018-13, Changes to the Disclosure Requirements for Fair Value Measurement ("ASU 2018-13") In August 2018, the FASB issued ASU 2018-13 which amends fair value measurement disclosure requirements to eliminate, add and modify certain disclosures to improve the effectiveness of such disclosure in the notes to the financial statements. ASU 2018-13 will be effective for interim and annual periods beginning after December 15, 2019. Early adoption is permitted. The Company early adopted ASU 2018-13 on January 1, 2019. The adoption of ASU 2018-13 did not have a material impact to the Company's consolidated financial statements. ASU No. 2018-14, Changes to the Disclosure Requirements for Defined Benefit Plans ("ASU 2018-14") In August 2018, the FASB issued ASU 2018-14 which amends defined benefit plan disclosure requirements to eliminate, add and modify certain disclosures to improve the effectiveness of such disclosure in the notes to the financial statements. ASU 2018-14 will be effective for interim and annual periods beginning after December 15, 2021. Early adoption is permitted. The Company early adopted ASU 2018-14 on January 1, 2019. The adoption of ASU 2018-14 did not have a material impact to the Company's consolidated financial statements. ASU No. 2017-04, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”) In January 2017, the FASB issued ASU 2017-04 which eliminates step two from the goodwill impairment test. Under the new standard, to the extent the carrying amount of a reporting unit exceeds the fair value, the Company will record an impairment charge equal to the difference. ASU 2017-04 will be effective for interim and annual periods beginning after December 15, 2019. The Company elected to early adopt ASU 2017-04 in connection with the completion of its November 30, 2019 annual impairment assessment. The adoption of ASU 2017-04 did not have a material impact to the Company's consolidated financial statements. Accounting Standards Adopted January 1, 2020 ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) In June 2016, the FASB issued ASU 2016-13, which requires a financial asset (or a group of financial assets) measured at amortized cost basis to be assessed for impairment under the current expected credit loss model rather than an incurred loss model. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount. The primary financial assets of the Company in scope of ASU 2016-13 include accounts receivables and equipment installment plan notes receivables. The Company adopted ASU 2016-13 on January 1, 2020. The adoption of ASU 2016-13 did not have a material impact to the Company's consolidated financial statements. ASU No. 2018-15, Customer’s Accounting for Implementation Costs in a Cloud Computing Arrangement That Is a Service Contract ("ASU 2018-15") In August 2018, the FASB issued ASU 2018-15 which requires upfront implementation costs incurred in a cloud computing arrangement (or hosting arrangement) that is a service contract to be amortized to hosting expense over the term of the arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. The Company adopted ASU 2018-15 on January 1, 2020. The adoption of ASU 2018-15 did not have a material impact to the Company's consolidated financial statements. ASU No. 2019-02, Improvements to Accounting for Costs of Films and License Agreements for Program Materials ("ASU 2019-02") In March 2019, the FASB issued ASU 2019-02 which aligns the accounting for production costs of an episodic television series with the accounting for production costs of films regarding cost capitalization, amortization, impairment, presentation and disclosure. The Company adopted ASU 2019-02 on January 1, 2020. The adoption of ASU 2019-02 did not have a material impact to the Company's consolidated financial statements. Accounting Standards Not Yet Adopted ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”) In December 2019, the FASB issued ASU 2019-12, which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Summary of Significant Accounting Policies [Abstract]
Consolidation Policy	Consolidation The accompanying consolidated financial statements include the accounts of Charter and all entities in which Charter has a controlling interest, including variable interest entities ("VIEs") where Charter is the primary beneficiary. The Company consolidates based upon evaluation of the Company’s power, through voting rights or similar rights, to direct the activities of another entity that most significantly impact the entity’s economic performance; its obligation to absorb the expected losses of the entity; and its right to receive the expected residual returns of the entity. Charter controls and consolidates Charter Holdings. The noncontrolling interest on the Company’s balance sheet primarily represents Advance/Newhouse Partnership's (“A/N”) minority equity interests in Charter Holdings. See Note 11. All significant intercompany accounts and transactions among consolidated entities have been eliminated in consolidation.
Cash and Cash Equivalents Policy	Cash and Cash Equivalents
Restricted Cash Policy	Restricted Cash Restricted cash represents amounts held in escrow related to the Company's build-to-suit lease arrangement with a VIE. See Note 6. The amounts held in escrow are classified as noncurrent restricted cash in the Company's consolidated balance sheets. The Company's restricted cash was primarily invested in a federal funds deposit account.
Property, Plant and Equipment Policy	Property, Plant and Equipment Additions to property, plant and equipment are recorded at cost, including all material, labor and certain indirect costs associated with the construction of cable transmission and distribution facilities. While the Company’s capitalization is based on specific activities, once capitalized, costs are tracked on a composite basis by fixed asset category at the cable system level and not on a specific asset basis. For assets that are sold or retired, the estimated historical cost and related accumulated depreciation is removed. Costs associated with the placement of the customer drop to the dwelling and the placement of outlets within a dwelling along with the costs associated with the deployment of new customer premise equipment necessary to provide video, Internet or voice services are capitalized. Costs capitalized include materials, direct labor and overhead costs. The Company capitalizes direct labor and overhead using standards developed from actual costs and applicable operational data. The Company calculates standards annually (or more frequently if circumstances dictate) for items such as the labor rates, overhead rates, and the actual amount of time required to perform a capitalizable activity. Overhead costs are associated with the activities of the Company’s personnel who assist in installation activities and consist of compensation and other indirect costs associated with these support functions. Indirect costs primarily include employee benefits and payroll taxes, and vehicle and occupancy costs. The costs of disconnecting service and removing customer premise equipment from a dwelling and the costs to reconnect a customer drop or to redeploy previously installed customer premise equipment are charged to operating expense as incurred. Costs for repairs and maintenance are charged to operating expense as incurred, while plant and equipment replacement, including replacement of certain components, betterments, including replacement of cable drops and outlets, are capitalized. Depreciation is recorded using the straight-line composite method over management’s estimate of the useful lives of the related assets as follows: Cable distribution systems 8-20 years Customer premise equipment and installations 3-8 years Vehicles and equipment 6-21 years Buildings and improvements 10-40 years Furniture, fixtures and equipment 2-10 years
Asset Retirement Obligations Policy	Asset Retirement Obligations Certain of the Company’s franchise agreements and leases contain provisions requiring the Company to restore facilities or remove equipment in the event that the franchise or lease agreement is not renewed. The Company expects to continually renew its franchise agreements and therefore cannot reasonably estimate any liabilities associated with such agreements. A remote possibility exists that franchise agreements could be terminated unexpectedly, which could result in the Company incurring significant expense in complying with restoration or removal provisions. The Company does not have any significant liabilities related to asset retirements recorded in its consolidated financial statements.
Valuation of Long-Lived Assets Policy	Valuation of Long-Lived Assets The Company evaluates the recoverability of long-lived assets (e.g., property, plant and equipment and finite-lived intangible assets) to be held and used when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Such events or changes in circumstances could include such factors as impairment of the Company’s indefinite life assets, changes in technological advances, fluctuations in the fair value of such assets, adverse changes in relationships with local franchise authorities, adverse changes in market conditions or a deterioration of current or expected future operating results. If a review indicates that the carrying value of such asset is not recoverable from estimated undiscounted cash flows, the carrying value of such asset is reduced to its estimated fair value. While the Company believes that its estimates of future cash flows are reasonable, different assumptions regarding such cash flows could materially affect its evaluations of asset recoverability. No impairments of long-lived assets held for use were recorded in 2019 , 2018 and 2017 . For non-strategic long-lived assets held for sale and ultimately sold, the Company recorded impairments of approximately $41 million and $75 million during the years ended December 31, 2019 and 2018, respectively, to other operating expenses, net.
Leases Policy	Leases The primary leased asset classes of the Company include real estate, dark fiber, colocation facilities and other equipment. The lease agreements include both lease and non-lease components, which the Company accounts for separately depending on the election made for each leased asset class. For real estate and dark fiber leased asset classes, the Company accounts for lease and non-lease components as a single lease component and includes all fixed payments in the measurement of lease liabilities and lease assets. For colocation facilities leased asset class, the Company accounts for lease and non-lease components separately including only the fixed lease payment component in the measurement of lease liabilities and lease assets. In addition to fixed lease payments, certain of the Company’s lease agreements include variable lease payments which are tied to an index or rate such as the change in the Consumer Price Index. These variable payments are not included in the measurement of the lease liabilities and lease assets. Lease assets and lease liabilities are initially recognized based on the present value of the future lease payments over the expected lease term. As for most leases the implicit rate is not readily determinable, the Company uses a discount rate in determining the present value of future payments based on the yield-to-maturity of the Company’s secured publicly traded United States dollars denominated debt instruments interpolating the duration of the debt to the term of the executed lease. The Company’s leases have base rent periods and some with optional renewal periods. Leases with base rent periods of less than 12 months are not recorded on the balance sheet. For purposes of measurement of lease liabilities, the expected lease terms may include renewal options when it is reasonably certain that the Company will exercise such options. Based on conditions of the Company's existing leases and its overall business strategies, the majority of the Company's renewal options are not reasonably certain in determining the expected lease term. The Company will periodically reassess expected lease terms (and purchase options, if applicable) based on significant triggering events or compelling economic reasons to exercise such options. The Company’s primary lease income represents sublease income on certain real estate leases. Sublease income is included in other revenue and presented gross from rent expense. For customer premise equipment ("CPE") where such CPE would qualify as a lease, the Company applies the practical expedient to combine the operating lease with the subscription service revenue as a single performance obligation in accordance with revenue recognition accounting guidance as the subscription service is the predominant component.
Other Noncurrent Assets Policy	Other Noncurrent Assets Other noncurrent assets primarily include investments, trademarks, customer contract costs and other intangible assets. The Company accounts for its investments in less than majority owned investees under either the equity method or as equity securities. The Company applies the equity method to investments when it has the ability to exercise significant influence over the operating and financial policies of the investee. The Company’s share of the investee’s earnings (losses) is included in other expense, net in the consolidated statements of operations. The Company monitors its investments for indicators that a decrease in investment value has occurred that is other than temporary. If it has been determined that an investment has sustained an other than temporary decline in value, the investment is written down to fair value with a charge to earnings. Investments acquired are measured at fair value utilizing the acquisition method of accounting. The difference between the fair value and the amount of underlying equity in net assets for most equity method investments is due to previously unrecognized intangible assets at the investee. These amounts are amortized as a component of equity earnings (losses), recorded within other expense, net over the estimated useful life of the asset. Trademarks have been determined to have an indefinite life and are tested annually for impairment. Customer contract costs are deferred in other noncurrent assets for upfront costs incurred to obtain a customer contract and upfront costs to fulfill a customer contract, as further discussed below under the Customer Contract Costs accounting policy.
Revenue Recognition Policy	Revenue Recognition Nature of Services Residential Services Residential customers are offered video, Internet, and voice services primarily on a subscription basis. Residential customers may generally cancel their subscriptions at the end of their monthly service period without penalty. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized ratably over the monthly service period as the subscription services are delivered. Each optional service purchased is generally accounted for as a distinct performance obligation when purchased and revenue is recognized when the service is provided. Residential video customers have the option to purchase additional tiers of services, as well as video-on-demand (“VOD”) programming and pay-per-view programming on a per-event basis. Video revenues consist primarily of revenues from the selected programming service tier, as well as VOD fees, pay-per-view fees, retransmission fees, regulatory fees, equipment service fees and video installation fees. Residential Internet customers receive data download and upload services with speeds dependent on the selected tier of service. Customers are also offered a security suite, an in-home WiFi product, and an out-of-home WiFi service. Internet revenues consist primarily of data services, WiFi service fees and Internet installation fees. Residential voice customers receive unlimited local and long distance calling to United States, Canada, Mexico, and Puerto Rico, voicemail, call waiting, caller ID, call forward and other features. Customers may also purchase international calling either by the minute, or through packages of minutes per month. Voice revenues consist primarily of voice services and regulatory fees. Small and Medium Business Small and medium business customers are offered video, Internet and voice services similar to those provided to residential customers. Small and medium business customers may generally cancel their subscriptions at the end of their monthly service period without penalty. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized ratably over the monthly service period as the subscription services are delivered. Enterprise Services to enterprise clients include more tailored communications products and managed service solutions to larger businesses, as well as high-capacity last-mile data connectivity services to mobile and wireline carriers on a wholesale basis. Services are primarily offered on a subscription basis with a contractually specified and non-cancelable service period. Each subscription service provided is accounted for as a distinct performance obligation and revenue is recognized ratably over the contract period as the subscription services are delivered. Enterprise subscription services are billed as monthly recurring charges to customers and related installation services, if applicable, are billed upon completion of the customer installation. Installation services are not accounted for as distinct performance obligations, but rather a component of the connectivity services, and therefore upfront installation fees are deferred and recognized as revenue over the related contract period. Advertising Services The Company offers local, regional and national businesses the opportunity to advertise in individual and multiple service areas on cable television networks and digital outlets. Placement of advertising is accounted for as a distinct performance obligation and revenue is recognized at the point in time when the advertising is distributed. In some service areas, the Company has formed advertising interconnects or entered into representation agreements with other video distributors, under which the Company sells advertising on behalf of those distributors. In other service areas, the Company has entered into representation agreements under which another operator in the area will sell advertising on the Company’s behalf. For representation arrangements in which the Company controls the sale of advertising and acts as the principal to the transaction, the Company recognizes revenue earned from the advertising customer on a gross basis and the amount remitted to the distributor as an operating expense. For other representation arrangements in which the Company does not control the sale of advertising and acts as an agent to the transaction, the Company recognizes revenue net of any fee remitted to the distributor. Mobile We also offer mobile service to residential customers and recently launched mobile service to small and medium business customers. Mobile services are sold under an unlimited data plan or a by-the-gig data usage plan and revenue is recognized ratably over the monthly service period as the services are delivered. Customers can purchase mobile equipment, including devices and accessory products, and have the option to pay for devices under interest-free monthly installment plans. The sale of equipment is a separate performance obligation. Revenue is recognized from the sale of equipment upon delivery and acceptance by the customer, as this is when control passes to the customer. The Company’s revenues by product line are as follows: Year Ended December 31, 2019 2018 2017 Video $ 17,607 $ 17,348 $ 16,621 Internet 16,667 15,181 14,101 Voice 1,920 2,114 2,542 Residential revenue 36,194 34,643 33,264 Small and medium business 3,868 3,665 3,547 Enterprise 2,556 2,528 2,373 Commercial revenue 6,424 6,193 5,920 Advertising sales 1,568 1,785 1,510 Mobile 726 106 — Other 852 907 887 $ 45,764 $ 43,634 $ 41,581 Fees imposed on the Company by various governmental authorities are passed through on a monthly basis to the Company’s customers and are periodically remitted to authorities. Fees of $1.1 billion , $1.0 billion and $961 million for the years ended December 31, 2019 , 2018 and 2017 , respectively, are reported in video, voice, mobile and commercial revenues, on a gross basis with a corresponding operating expense because the Company is acting as a principal. Certain taxes, such as sales taxes imposed on the Company’s customers, collected and remitted to state and local authorities, are recorded on a net basis because the Company is acting as an agent in such situations. A significant portion of our revenue is derived from customers who may generally cancel their monthly subscriptions at any time without penalty. As such, the amount of revenue related to unsatisfied performance obligations is not necessarily indicative of the future revenue to be recognized from our existing customer base. Revenue from customers with a contractually specified term and non-cancelable service period will be recognized over the term of such contracts, which is generally two to seven years for our enterprise contracts with a weighted average term of approximately three years. Significant Judgments in Evaluating Revenue Recognition The Company often provides multiple services to a customer. Provision of customer premise equipment, installation services, and additional service tiers may have a significant level of integration and interdependency with the subscription video, Internet, voice, or connectivity services provided. Judgment is required to determine whether provision of customer premise equipment, installation services, and additional service tiers are considered distinct and accounted for separately, or not distinct and accounted for together with the subscription services. Allocation of the transaction price to the distinct performance obligations in bundled residential service subscriptions requires judgment. The transaction price for a bundle of residential services is frequently less than the sum of the standalone selling prices of each individual service. The Company allocates the residential services bundle discount among the services to which the discount relates based on the relative standalone selling prices of those services. Standalone selling prices for the Company’s residential video and Internet services are directly observable, while standalone selling price for the Company’s residential voice service is estimated using the adjusted market assessment approach which relies upon information from peers and competitors who sell residential voice services individually. The Company believes residential and small and medium business non-refundable upfront installation fees charged to customers result in a material right to renew the contract as such fees are not required to be paid upon subsequent renewals. The residential and small and medium business upfront fee is deferred over the period the fee remains material to the customer, which the Company has estimated to be approximately six months. Estimation of the period the fee remains material to the customer requires consideration of both quantitative and qualitative factors including average installation fee, average revenue per customer, and customer behavior, among others. Deferred Revenue Contract Liabilities Timing of revenue recognition may differ from the timing of invoicing to customers. Residential, small and medium business, and enterprise customers are invoiced for subscription services in advance of the service period. Deferred revenue liabilities, or contract liabilities, are recorded when the Company collects payments in advance of performing the services. Deferred revenue liabilities, or contract liabilities, are also recorded when the Company invoices customers upfront for installation services that are recognized as revenue over time. Residential and small and medium business installation revenues are deferred over the period the fee remains material to the customer. Enterprise installation revenues are deferred using a portfolio approach over the average contract life of each enterprise service category. As of December 31, 2019 and 2018 , current deferred revenue liabilities consisting of customer prepayments of $366 million and $410 million , respectively, and upfront installation fees of $94 million and $84 million , respectively, were included in accounts payable and accrued liabilities. As of December 31, 2019 and 2018 , long-term deferred revenue liabilities consisting of enterprise upfront installation fees of $34 million
Customer Contract Costs Policy	Customer Contract Costs The Company recognizes an asset for incremental costs of obtaining a contract with a customer if the amortization period of those costs is expected to be longer than one year and the costs are expected to be recovered. Enterprise sales commission costs meet the requirements to be deferred and, as a result, are recognized using a portfolio approach over a commission expense weighted-average enterprise contract period. Deferred enterprise commission costs are included in other noncurrent assets in the consolidated balance sheet and totaled $143 million and $142 million as of December 31, 2019 and 2018 , respectively. As the amortization period of residential and small and medium business commissions costs is less than one year, the Company applies the practical expedient that allows such costs to be expensed as incurred. The Company has determined that the amortization period associated with residential and small and medium business commission costs is less than one year based on qualitative and quantitative factors. The Company recognizes an asset for costs incurred to fulfill a contract when those costs are directly related to services provided under the contract, generate or enhance resources of the entity that will be used in performing service obligations under the contract, and are expected to be recovered. Right-of-entry costs represent upfront costs incurred related to agreements entered into with multiple dwelling units (“MDUs”) including landlords, real estate companies or owners to gain access to a building in order to market and service customers who reside in the building. Right-of-entry costs meet the requirements to be deferred and, as a result, are recognized over the term of the contracts. Deferred right-of-entry costs are included in other noncurrent assets in the consolidated balance sheet and totaled $284 million and $273 million as of December 31, 2019 and 2018 , respectively. Amortization expense of $67 million and $62 million was included in regulatory, connectivity and produced content within operating costs and expenses in the consolidated statements of operations for the year ended December 31, 2019 and 2018 , respectively. Residential and small and medium business installation costs not capitalized into property, plant and equipment are expensed as incurred under cable industry-specific guidance.
Programming Costs Policy	Programming Costs The Company has various contracts to obtain video programming from vendors whose compensation is typically based on a flat fee per customer. The cost of the right to exhibit network programming under such arrangements is recorded in operating expenses in the month the programming is available for exhibition. Programming costs are paid each month based on calculations performed by the Company and are subject to periodic audits performed by the programmers. Certain programming contracts contain cash and non-cash consideration from the programmers. If consideration received does not relate to a separate product or service, the Company recognizes the consideration on a straight-line basis over the life of the programming agreement as a reduction of programming expense. Programming costs included in the statements of operations were $11.3 billion , $11.1 billion and $10.6 billion for the years ended December 31, 2019 , 2018 and 2017
Advertising Costs Policy	Advertising Costs Advertising costs associated with marketing the Company’s products and services are generally expensed as costs are incurred.
Multiple-Element Transactions Policy	Multiple-Element Transactions In the normal course of business, the Company enters into multiple-element transactions where it is simultaneously both a customer and a vendor with the same counterparty or in which it purchases multiple products and/or services, or settles outstanding items contemporaneous with the purchase of a product or service from a single counterparty. Transactions, although negotiated contemporaneously, may be documented in one or more contracts. The Company’s policy for accounting for each transaction negotiated contemporaneously is to record each element of the transaction based on the respective estimated fair values of the products or services purchased and the products or services sold. In determining the fair value of the respective elements, the Company refers to quoted market prices (where available), historical transactions or comparable cash transactions. Cash consideration received from a vendor is recorded as a reduction in the price of the vendor’s product unless (i) the consideration is for the reimbursement of a specific, incremental, identifiable cost incurred, in which case the cash consideration received would be recorded as a reduction in such cost (e.g., marketing costs), or (ii) an identifiable benefit in exchange for the consideration is provided, in which case revenue would be recognized for this element.
Stock-Based Compensation Policy	Stock-Based Compensation Restricted stock, restricted stock units, stock options as well as equity awards with market conditions are measured at the grant date fair value and amortized to stock compensation expense over the requisite service period. The fair value of options is estimated on the date of grant using the Black-Scholes option-pricing model and the fair value of equity awards with market conditions is estimated on the date of grant using Monte Carlo simulations. The grant date weighted average assumptions used during the years ended December 31, 2019 , 2018 and 2017 , respectively, were: risk-free interest rate of 2.5% , 2.4% and 1.8% ; expected volatility of 27% , 25% and 25% ; and expected lives of 4.9 years, 5.1 years and 4.6 years. The Company’s volatility assumptions represent management’s best estimate and were based on historical volatility. Expected lives were estimated using historical exercise data. The valuations assume no dividends are paid. The Company has elected an accounting policy to assume zero forfeitures for stock awards grants and account for forfeitures when they occur.
Defined Benefit Pension Plans Policy	Defined Benefit Pension Plans The Company sponsors three qualified defined benefit pension plans and one nonqualified defined benefit pension plan that provide pension benefits to a majority of employees who were employed by Time Warner Cable Inc. ("TWC") before the merger with TWC. Pension benefits are based on formulas that reflect the employees’ years of service and compensation during their employment period. Actuarial gains or losses are changes in the amount of either the benefit obligation or the fair value of plan assets resulting from experience different from that assumed or from changes in assumptions. The Company has elected to follow a mark-to-market pension accounting policy for recording the actuarial gains or losses annually during the fourth quarter, or earlier if a remeasurement event occurs during an interim period.
Income Taxes Policy	Income Taxes The Company recognizes deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities and expected benefits of utilizing loss carryforwards. Since substantially all the Company’s operations are held through its partnership interest in Charter Holdings, the primary deferred tax component recorded in the consolidated balance sheet relates to the excess financial reporting outside basis, excluding amounts attributable to nondeductible goodwill, over Charter’s tax basis in its investment in the partnership. Valuation allowances are established when management determines that it is more likely than not that some portion or the entire deferred tax asset will not be realized. The impact on deferred taxes of changes in tax rates and tax law, if any, applied to the years during which temporary differences are expected to be settled, are reflected in the consolidated financial statements in the period of enactment. In determining the Company’s tax provision for financial reporting purposes, the Company establishes a reserve for uncertain tax positions unless such positions are determined to be “more likely than not” of being sustained upon examination, based on their technical merits. There is considerable judgment involved in making such a determination. Interest and penalties are recognized on uncertain income tax positions as part of the income tax provision. See Note 17.
Segments Policy	Segments The Company’s operations are managed and reported to its Chief Executive Officer (“CEO”), the Company’s chief operating decision maker, on a consolidated basis. The CEO assesses performance and allocates resources based on the consolidated results of operations. Under this organizational and reporting structure, the Company has one reportable segment, cable services.

Franchises, Goodwill and Othe_2

Franchises, Goodwill and Other Intangible Assets (Policies)	12 Months Ended
	Dec. 31, 2019
Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Policy	Franchise rights represent the value attributed to agreements or authorizations with local and state authorities that allow access to homes in cable service areas. For valuation purposes, they are defined as the future economic benefits of the right to solicit and service potential customers (customer marketing rights), and the right to deploy and market new services to potential customers (service marketing rights). Management estimates the fair value of franchise rights at the date of acquisition and determines if the franchise has a finite life or an indefinite life. The Company has concluded that all of its franchises qualify for indefinite life treatment given that there are no legal, regulatory, contractual, competitive, economic or other factors which limit the period over which these rights will contribute to the Company's cash flows. The Company reassesses this determination periodically or whenever events or substantive changes in circumstances occur. All franchises are tested for impairment annually or more frequently as warranted by events or changes in circumstances. Franchise assets are aggregated into essentially inseparable units of accounting to conduct valuations. The units of accounting generally represent geographical clustering of the Company's cable systems into groups. The Company assesses qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that an indefinite lived intangible asset has been impaired. If, after this optional qualitative assessment, the Company determines that it is not more likely than not that an indefinite lived intangible asset has been impaired, then no further quantitative testing is necessary. In completing the qualitative impairment testing, the Company evaluates a multitude of factors that affect the fair value of our franchise assets. Examples of such factors include environmental and competitive changes within our operating footprint, actual and projected operating performance, the consistency of our operating margins, equity and debt market trends, including changes in our market capitalization, and changes in our regulatory and political landscape, among other factors. The Company performed a qualitative assessment in 2019 , which also included consideration of a fair value appraisal performed for tax purposes in the beginning of 2019 as of a December 31, 2018 valuation date (the "Appraisal"). After consideration of the qualitative factors in 2019 , including the results of the Appraisal, the Company concluded that it is more likely than not that the fair value of the franchise assets in each unit of accounting exceeds the carrying value of such assets and therefore did not perform a quantitative analysis at the assessment date. Periodically, the Company will elect to perform a quantitative analysis for impairment testing. If the Company elects or is required to perform a quantitative analysis to test its franchise assets for impairment, the methodology described below is utilized. If a quantitative analysis is performed, the estimated fair value of franchises is determined utilizing an income approach model based on the present value of the estimated discrete future cash flows attributable to each of the intangible assets identified assuming a discount rate. The fair value of franchises is determined based on estimated discrete discounted future cash flows using assumptions consistent with internal forecasts. The franchise after-tax cash flow is calculated as the after-tax cash flow generated by the potential customers obtained. The sum of the present value of the franchises’ after-tax cash flow in years 1 through 10 and the continuing value of the after-tax cash flow beyond year 10 yields the fair value of the franchises. This approach makes use of unobservable factors such as projected revenues, expenses, capital expenditures, customer trends, and a discount rate applied to the estimated cash flows. The determination of the franchise discount rate is derived from the Company’s weighted average cost of capital, which uses a market participant’s cost of equity and after-tax cost of debt and reflects the risks inherent in the cash flows. The Company estimates discounted future cash flows using reasonable and appropriate assumptions including among others, penetration rates; revenue growth rates; operating margins; and capital expenditures. The assumptions are based on the Company’s and its peers’ historical operating performance adjusted for current and expected competitive and economic factors surrounding the cable industry. The estimates and assumptions made in the Company’s valuations are inherently subject to significant uncertainties, many of which are beyond its control, and there is no assurance that these results can be achieved. The primary assumptions for which there is a reasonable possibility of the occurrence of a variation that would significantly affect the measurement value include the assumptions regarding revenue growth, programming expense growth rates, the amount and timing of capital expenditures, actual customer trends and the discount rate utilized. The Company has determined that it has one reporting unit for purposes of the assessment of goodwill impairment. The fair value of the reporting unit is determined using both an income approach and market approach. The Company’s income approach model used for its reporting unit valuation is consistent with that used for its franchise valuation noted above except that cash flows from the entire business enterprise are used for the reporting unit valuation. The Company’s market approach model estimates the fair value of the reporting unit based on market prices in actual precedent transactions of similar businesses and market valuations of guideline public companies. Goodwill is tested for impairment as of November 30 of each year , or more frequently as warranted by events or changes in circumstances. Accounting guidance also permits an optional qualitative assessment for goodwill to determine whether it is more likely than not that the carrying value of a reporting unit exceeds its fair value. If, after this qualitative assessment, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount then no further quantitative testing would be necessary. A quantitative assessment is performed if the qualitative assessment results in a more likely than not determination or if a qualitative assessment is not performed. The quantitative assessment considers whether the carrying amount of a reporting unit exceeds its fair value, in which case an impairment charge is recorded to the extent the reporting unit’s carrying value exceeds its fair value. As with the Company’s franchise impairment testing, in 2019 the Company elected to perform a qualitative goodwill impairment assessment, which incorporated the results of the Appraisal and consideration of the same qualitative factors relevant to the Company's franchise impairment testing. As a result of that assessment, the Company concluded that goodwill is not impaired. Customer relationships are recorded at fair value as of the date acquired less accumulated amortization. Customer relationships, for valuation purposes, represent the value of the business relationship with existing customers, and are calculated by projecting the discrete future after-tax cash flows from these customers, including the right to deploy and market additional services to these customers. The present value of these after-tax cash flows yields the fair value of the customer relationships. The use of different valuation assumptions or definitions of franchises or customer relationships, such as our inclusion of the value of selling additional services to our current customers within customer relationships versus franchises, could significantly impact our valuations and any resulting impairment. Customer relationships are amortized on an accelerated sum of years’ digits method over useful lives of 8 - 15 years based on the period over which current customers are expected to generate cash flows. The Company periodically evaluates the remaining useful lives of its customer relationships to determine whether events or circumstances warrant revision to the remaining periods of amortization. Customer relationships are evaluated for impairment upon the occurrence of events or changes in circumstances indicating that the carrying amount of an asset may not be recoverable. Customer relationships are deemed impaired when the carrying value exceeds the projected undiscounted future cash flows associated with the customer relationships. No impairment of customer relationships was recorded in the years ended December 31, 2019 , 2018 or 2017 . The fair value of trademarks is determined using the relief-from-royalty method, a variation of the income approach, which applies a fair royalty rate to estimated revenue derived under the Company’s trademarks. The fair value of the intangible is estimated to be the present value of the royalty saved because the Company owns the trademarks. Royalty rates are estimated based on a review of market royalty rates in the communications and entertainment industries. As the Company expects to continue to use each trademark indefinitely, trademarks have been assigned an indefinite life and are tested annually for impairment using either a qualitative analysis or quantitative analysis as elected by management. As with the Company’s franchise impairment testing, in 2019 the Company elected to perform a qualitative trademark impairment assessment and concluded that trademarks are not impaired.
