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 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.
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 2024, 2023 and 2022.
Fair Value Measurements Policy | 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. The Company estimates the fair value of its financial instruments 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 Company’s nonfinancial assets such as equity method investments, franchises, property, plant, and equipment, and other intangible assets are not measured at fair value on a recurring basis; however, they are subject to fair value adjustments in certain circumstances, such as when there is evidence that an impairment may exist. When such impairments are recorded, fair values are generally classified within Level 3 of the valuation hierarchy. The carrying amounts of cash and cash equivalents, receivables, payables and other current assets and liabilities approximate fair value because of the short maturity of those instruments.
Government Assistance Policy | Government Assistance The Company's government assistance primarily consists of federal subsidies from the Rural Development Opportunity Fund (“RDOF”) and state broadband grants primarily funded by the American Rescue Plan Act of 2021 (“ARPA”). The Company was awarded approximately $1.1 billion in federal subsidies in phase I of the RDOF auction to be received monthly over ten years to deploy and operate broadband services to unserved communities to more than one million estimated passings. For accounting purposes, RDOF subsidies are recorded as other revenues since the primary conditions for the receipt of the subsidies are the build out and operation of the broadband network over the ten years. During the years ended December 31, 2024, 2023 and 2022, other revenues included approximately $108 million, $116 million and $107 million of RDOF subsidy revenue, respectively. The Company has also been awarded broadband grants to construct broadband infrastructure to unserved and underserved communities by various state and local governments. As of December 31, 2024, the Company has been publicly awarded approximately $1.3 billion in state grants, of which approximately $1.1 billion of these state grants have been formalized into executed agreements. State grants are either a fixed subsidy or variable with a subsidy cap conditioned upon construction. Cash is paid either upon project completion, milestone completion, or in some instances a portion of grant is paid in advance. Prefunded grants are subject to recapture if buildouts are not completed. For accounting purposes state broadband grants are generally recorded as a reduction to property, plant and equipment using a percentage of completion, since the primary conditions for these grants are to build out the broadband network. During the years ended December 31, 2024, 2023 and 2022, the amount of state broadband grants recorded in the consolidated financial statements was not material.
Advertising Costs Policy | Advertising Costs Advertising costs associated with marketing the Company’s products and services are generally expensed as costs are incurred.
