DESCRIPTION OF BUSINESS AND RELATED MATTERS	DESCRIPTION OF BUSINESS AND RELATED MATTERS The Company and Related Matters Altice USA, Inc. ("Altice USA") was incorporated in Delaware on September 14, 2015. Altice USA is majority-owned by Patrick Drahi through Next Alt. S.à.r.l. ("Next Alt"). Patrick Drahi also controls Altice Group Lux S.à.r.l, formerly Altice Europe N.V. ("Altice Europe") and its subsidiaries and other entities. Altice USA is a holding company that does not conduct any business operations of its own. Altice Europe, through a subsidiary, acquired Cequel Corporation ("Cequel") on December 21, 2015 (the "Cequel Acquisition") and Cequel was contributed to Altice USA on June 9, 2016. Altice USA acquired Cablevision Systems Corporation ("Cablevision") on June 21, 2016 (the "Cablevision Acquisition"). Altice USA, through CSC Holdings, LLC (a wholly-owned subsidiary of Cablevision) and its consolidated subsidiaries ("CSC Holdings," and collectively with Altice USA, the "Company"), principally provides broadband communications and video services in the United States. It had marketed its residential services primarily under two brands: Optimum, primarily in the New York metropolitan area, and Suddenlink, principally in markets in the south-central United States. On August 1, 2022, the Company began marketing the Suddenlink services under the Optimum brand. It operates enterprise services under the brands Lightpath and Optimum Business. It delivers broadband, video, telephony services, proprietary content and advertising services to residential and business customers. In addition, the Company offers a full service mobile offering to consumers across its footprint. As these brands are managed on a consolidated basis, the Company classifies its operations in one segment. The accompanying consolidated financial statements ("consolidated financial statements") of Altice USA include the accounts of Altice USA and its majority-owned subsidiaries and the accompanying consolidated financial statements of CSC Holdings include the accounts of CSC Holdings and its majority-owned subsidiaries. The consolidated balance sheets and statements of operations of Altice USA are essentially identical to the consolidated balance sheets and statements of operations of CSC Holdings, with the following exceptions: Altice USA primarily has additional cash and deferred taxes on its consolidated balance sheet. In addition, CSC Holdings and its subsidiaries have certain intercompany receivables from and payables to Altice USA. Differences between Altice USA's results of operations and those of CSC Holdings primarily include loss on investments, net in 2020, and income tax expense in 2022, 2021 and 2020. The combined notes to the consolidated financial statements relate to the Company, which, except as noted, are essentially identical for Altice USA and CSC Holdings. All significant intercompany transactions and balances between Altice USA and CSC Holdings and their respective consolidated subsidiaries are eliminated in both sets of consolidated financial statements. Intercompany transactions between Altice USA and CSC Holdings are not eliminated in the CSC Holdings consolidated financial statements, but are eliminated in the Altice USA consolidated financial statements. The financial statements of CSC Holdings are included herein as supplemental information as CSC Holdings is not an SEC registrant. Share Repurchase Plan In June 2018, the Board of Directors of Altice USA authorized a share repurchase program of $2,000,000 , and on July 30, 2019, the Board of Directors authorized a new incremental three-year share repurchase program of $5,000,000 that took effect following the completion in August 2019 of the $2,000,000 repurchase program. In November 2020, the Board of Directors authorized an additional $2,000,000 of share repurchases, bringing the total amount of cumulative share repurchases authorized to $9,000,000. Under these repurchase programs, shares of Altice USA Class A common stock may be purchased from time to time in the open market and may include trading plans entered into with one or more brokerage firms in accordance with Rule 10b5-1 under the Securities Exchange Act of 1934. Size and timing of these purchases will be determined based on market conditions and other factors. On November 23, 2020, the Company commenced a modified "Dutch auction" tender offer (the "Tender Offer") to purchase up to $2,500,000 in value of shares of its Class A Common Stock, at a price not greater than $36.00 per share nor less than $32.25 per share . The Tender Offer expired on December 21, 2020. On December 21, 2020, the Company accepted for purch ase 64,613,479 shares of its Class A Common Stock, at a price of $36.00 per share, plus related fees, for an aggregate purchase price of $2,326,949. The aggregate purchase price of these shares (including the fees relating to the Tender Offer), is reflected in stockholders' equity (deficiency) in the consolidated balance sheet of Altice USA as of December 31, 2020.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Summary of Significant Accounting Policies Revenue Recognition Residential Services The Company derives revenue through monthly charges to residential customers of its broadband, video, and telephony services, including installation services. In addition, the Company derives revenue from digital video recorder ("DVR"), video-on-demand ("VOD"), pay-per-view, and home shopping commissions which are reflected in "Residential video" revenues. The Company recognizes broadband, video, and telephony revenues as the services are provided to a customer on a monthly basis. Each service is accounted for as a distinct performance obligation. Revenue from the sale of bundled services at a discounted rate is allocated to each product based on the standalone selling price of each performance obligation within the bundled offer. The standalone selling price requires judgment and is typically determined based on the current prices at which the separate services are sold by the Company. Installation revenue for the Company's residential services is deferred and recognized over the benefit period, which is estimated to be less than one year. The estimated benefit period takes into account both quantitative and qualitative factors including the significance of average installation fees to total recurring revenue per customer. The Company is assessed non-income related taxes by governmental authorities, including franchising authorities (generally under multi-year agreements), and collects such taxes from its customers. In instances where the tax is being assessed directly on the Company, amounts paid to the governmental authorities are recorded as programming and other direct costs and amounts received from the customers are recorded as revenue. For the years ended December 31, 2022, 2021 and 2020, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $232,795, $257,364 and $257,405, respectively. Business and Wholesale Revenue The Company derives revenue from the sale of products and services to both large enterprise and small and medium-sized business ("SMB") customers, including broadband, telephony, networking, and video services reflected in "Business services and wholesale" revenues. The Company's business services also include Ethernet, data transport, and IP-based virtual private networks. The Company also provides managed services to businesses, including hosted telephony services (cloud based SIP-based private branch exchange), managed WiFi, managed desktop and server backup and managed collaboration services including audio and web conferencing. The Company also offers fiber-to-the-tower services to wireless carriers for cell tower backhaul, which enables wireline communications service providers to connect to customers that their own networks do not reach. The Company recognizes revenues for these services as the services are provided to a customer on a monthly basis. Substantially all of our SMB customers are billed monthly and large enterprise customers are billed in accordance with the terms of their contracts which is typically on a monthly basis. Contracts with large enterprise customers typically range from three News and Advertising Revenue As part of the agreements under which the Company acquires video programming, the Company typically receives an allocation of scheduled advertising time during such programming into which the Company's cable systems can insert commercials. In several of the markets in which the Company operates, it has entered into agreements commonly referred to as interconnects with other cable operators to jointly sell local advertising. In some of these markets, the Company represents the advertising sales efforts of other cable operators; in other markets, other cable operators represent the Company. The Company also offers customers the opportunity to advertise on digital platforms. Advertising revenues are recognized when the advertising is distributed. For 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 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. Revenue earned from the data-driven, audience-based advertising solutions using advanced analytics tools is recognized when services are provided. Affiliation fee revenue derived by our news business is recognized as the programming services are provided. Mobile Revenue The Company has a mobile service providing data, talk and text to consumers in or near our service areas. Customers can purchase or finance a variety of mobile devices. Revenue is recognized from the sale of equipment upon delivery and acceptance by the customer. Customers are billed monthly for access to and usage of our mobile services. The Company recognizes mobile service revenue as the services are provided to the customers. Other Revenue Revenues derived from other sources are recognized when services are provided or events occur. Customer Contract Costs Incremental costs incurred in obtaining a contract with a customer are deferred and recorded as an asset if the period of benefit is expected to be greater than one year. Sales commissions for enterprise customers are deferred and amortized over the average contract term. As the amortization period for sales commission expenses related to residential and SMB customers is less than one year, the Company is utilizing the practical expedient and is recognizing the costs when incurred. The costs of fulfilling a contract with a customer are deferred and recorded as an asset if they generate or enhance resources of the Company that will be used in satisfying future performance obligations and are expected to be recovered. Installation costs related to residential and SMB customers that are not capitalized as part of the initial deployment of new customer premise equipment are expensed as incurred pursuant to industry-specific guidance. Deferred enterprise sales commission costs are included in other current and noncurrent assets in the consolidated balance sheet and totaled $17,511 and $17,669 as of December 31, 2022 and 2021, respectively. A significant portion of our revenue is derived from residential and SMB customer contracts which are month-to month. 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. Contracts with enterprise customers generally range from three years to five years, and services may only be terminated in accordance with the contractual terms. The following table presents the composition of revenue: Years Ended December 31, 2022 2021 2020 Residential: Broadband $ 3,930,667 $ 3,925,089 $ 3,689,159 Video 3,281,306 3,526,205 3,670,859 Telephony 332,406 404,813 468,777 Business services and wholesale 1,473,837 1,586,044 1,454,532 News and advertising 520,293 550,667 519,205 Mobile 97,679 84,194 78,127 Other 11,471 13,837 13,983 Total revenue $ 9,647,659 $ 10,090,849 $ 9,894,642 Multiple-Element Transactions In the normal course of business, the Company may enter 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 contemporaneously with the purchase of a product or service, from a single counterparty. The Company's policy for accounting for each transaction negotiated contemporaneously is to record each deliverable of the transaction based on its best estimate of selling price in a manner consistent with that used to determine the price to sell each deliverable on a standalone basis. In determining the fair value of the respective deliverable, the Company utilizes historical transactions, quoted market prices (as available), or comparable transactions. Programming and Other Direct Costs Costs of revenue related to delivery of services and goods are classified as "programming and other direct costs" in the accompanying consolidated statements of operations. Programming Costs Programming expenses related to the Company's video service represent fees paid to programming distributors to license the programming distributed to video customers. This programming is acquired generally under multi-year distribution agreements, with rates usually based on the number of customers that receive the programming. If there are periods when an existing distribution agreement has expired and the parties have not finalized negotiations of either a renewal of that agreement or a new agreement for certain periods of time, the Company continues to carry and pay for these services until execution of definitive replacement agreements or renewals. The amount of programming expense recorded during the interim period is based on the Company's estimates of the ultimate contractual agreement expected to be reached, which is based on several factors, including previous contractual rates, customary rate increases and the current status of negotiations. Such estimates are adjusted as negotiations progress until new programming terms are finalized. In addition, the Company has received, or may receive, incentives from programming distributors for carriage of the distributors' programming. The Company generally recognizes these incentives as a reduction of programming costs and are recorded in "programming and other direct costs", generally over the term of the distribution agreement. Advertising Expenses Advertising costs are charged to expense when incurred and are reflected in "other operating expenses" in the accompanying consolidated statements of operations. Advertising costs amounted to $299,590, $274,639 and $213,474 for the years ended December 31, 2022, 2021 and 2020, respectively. Share-Based Compensation Share-based compensation expense which primarily relates to awards of stock options, restricted shares, performance stock units, and units in a carried unit plan is based on the fair value of share-based payment awards at the date of grant. The Company recognizes share-based compensation expense over the requisite service period or when it is probable any related performance condition will be met. For awards with graded vesting, compensation cost is recognized on an accelerated method under the graded vesting method over the requisite service period. Share-based compensation expense related to awards that vest entirely at the end of the vesting period are expensed on a straight-line basis. The Company accounts for forfeitures as they occur. See Note 15 to the consolidated financial statements for additional information about our share-based compensation. Income Taxes The Company's provision for income taxes is based on current period income, changes in deferred tax assets and liabilities and changes in estimates with regard to uncertain tax positions. Deferred tax assets are subject to an ongoing assessment of realizability. Cash and Cash Equivalents The Company's cash investments are placed with money market funds and financial institutions that are investment grade as rated by S&P Global Ratings and Moody's Investors Service. The Company selects money market funds that predominantly invest in marketable, direct obligations issued or guaranteed by the United States government or its agencies, commercial paper, fully collateralized repurchase agreements, certificates of deposit, and time deposits. The Company considers the balance of its investment in funds that substantially hold securities that mature within three months or less from the date the fund purchases these securities to be cash equivalents. The carrying amount of cash and cash equivalents either approximates fair value due to the short-term maturity of these instruments or are at fair value. Accounts Receivable Accounts receivable are recorded at net realizable value. 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. Investment Securities Investment securities and investment securities pledged as collateral are carried at fair value with realized and unrealized holding gains and losses included in the consolidated statements of operations. Long-Lived Assets and Amortizable Intangible Assets Property, plant and equipment, including construction materials, are carried at cost, and include all direct costs and certain indirect costs associated with the construction of cable systems, and the costs of new equipment installations. Equipment under finance leases is recorded at the present value of the total minimum lease payments. Depreciation on equipment is calculated on the straight-line basis over the estimated useful lives of the assets or, with respect to equipment under finance lease obligations and leasehold improvements, amortized over the lease term or the assets' useful lives and reported in depreciation and amortization (including impairments) in the consolidated statements of operations. The Company capitalizes certain internal and external costs incurred to acquire or develop internal-use software. Capitalized software costs are amortized over the estimated useful life of the software and reported in depreciation and amortization. Customer relationships, trade names and other intangibles established in connection with acquisitions that are finite-lived are amortized in a manner that reflects the pattern in which the projected net cash inflows to the Company are expected to occur, such as the sum of the years' digits method, or when such pattern does not exist, using the straight-line basis over their respective estimated useful lives. The Company reviews its long-lived assets (property, plant and equipment, and intangible assets subject to amortization) for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the expected cash flows, undiscounted and without interest, is less than the carrying amount of the asset, an impairment loss is recognized as the amount by which the carrying amount of the asset exceeds its fair value. Goodwill and Indefinite-Lived Intangible Assets Goodwill and the value of franchises acquired in business combinations which have indefinite useful lives are not amortized. Rather, such assets are tested for impairment annually or upon the occurrence of a triggering event. The Company assesses the recoverability of its goodwill annually, or more frequently whenever events or substantive changes in circumstances indicate that the carrying amount of its reporting units may exceed their fair value. The Company first considers qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more-likely- than-not that the fair value of a reporting unit is less than its carrying amount. 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 testing is performed. 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. The Company assesses qualitative factors to determine whether it is necessary to perform the quantitative identifiable indefinite-lived intangible assets impairment test. This quantitative test is required only if the Company concludes that it is more likely than not that a unit of accounting’s fair value is less than its carrying amount. When the qualitative assessment is not used, or if the qualitative assessment is not conclusive, the impairment test for other intangible assets not subject to amortization requires a comparison of the fair value of the intangible asset with its carrying value. If the carrying value of the indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Deferred Financing Costs Deferred financing costs, which are presented as a reduction of debt, are amortized to interest expense using the effective interest method over the terms of the related debt. Derivative Financial Instruments The Company accounts for derivative financial instruments as either assets or liabilities measured at fair value. The Company uses derivative instruments to manage its exposure to market risks from changes in certain equity prices and interest rates and does not hold or issue derivative instruments for speculative or trading purposes. These derivative instruments are not designated as hedges, and changes in the fair values of these derivatives are recognized in the consolidated statements of operations as gain (loss) on derivative contracts or gain (loss) on interest rate swap contracts. Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when the Company believes it is probable that a liability has been incurred and the amount of the contingency can be reasonably estimated. Foreign Currency Certain of the Company's subsidiaries (including subsidiaries of i24 News S.à.r.l ("i24NEWS")) are located outside the United States. The functional currency for these subsidiaries is determined based on the primary economic environment in which the subsidiary operates. Revenues and expenses for these subsidiaries are translated into U.S. dollars using rates that approximate those in effect during the period while the assets and liabilities are translated into U.S. dollars using exchange rates in effect at the end of each period. The resulting gains and losses from these translations are recognized in cumulative translation adjustment included in accumulated other comprehensive income (loss) in stockholders’/member's equity (deficiency) on the consolidated balance sheets.

Dividends and Distributions Altice USA Altice USA may pay dividends on its capital stock only from net profits and surplus as determined under Delaware law. If dividends are paid on the Altice USA common stock, holders of the Altice USA Class A common stock and Altice USA Class B common stock are entitled to receive dividends, and other distributions in cash, stock or property, equally on a per share basis, except that stock dividends with respect to Altice USA Class A common stock may be paid only with shares of Altice USA Class A common stock and stock dividends with respect to Altice USA Class B common stock may be paid only with shares of Altice USA Class B common stock. The Company's indentures restrict the amount of dividends and distributions in respect of any equity interest that can be made. During 2022, 2021 and 2020, there were no dividends paid to shareholders by Altice USA. CSC Holdings CSC Holdings may make distributions on its membership interests only if sufficient funds exist as determined under Delaware law. See Note 16 for a discussion of equity distributions that CSC Holdings made to its parent. Concentrations of Credit Risk Financial instruments that may potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents and trade account receivables. The Company monitors the financial institutions and money market funds where it invests its cash and cash equivalents with diversification among counterparties to mitigate exposure to any single financial institution. The Company's emphasis is primarily on safety of principal and liquidity and secondarily on maximizing the yield on its investments. Management believes that no significant concentration of credit risk exists with respect to its cash and cash equivalents because of its assessment of the creditworthiness and financial viability of the respective financial institutions. The Company did not have a single customer that represented 10% or more of its consolidated revenues for the years ended December 31, 2022, 2021 and 2020 or 10% or more of its consolidated net trade receivables at December 31, 2022, and 2021, respectively. Use of Estimates in Preparation of Financial Statements The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See Note 13 for a discussion of fair value estimates. Reclassifications Certain reclassifications have been made to the 2021 and 2020 amounts to conform to the 2022 presentation.

Accounting Changes and Error Corrections [Abstract]
CHANGE IN ACCOUNTING POLICIES AND ATS ACQUISITION	ACCOUNTING STANDARDS Accounting Standards Adopted in 2020 ASU No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04") In March 2020, the Financial Accounting Standards Board ("FASB") issued new accounting guidance related to the effects of reference rate reform on financial reporting. The guidance, effective for reporting periods through December 31, 2022, provides accounting relief for contract modifications that replace an interest rate impacted by reference rate reform (e.g., LIBOR) with a new alternative reference rate. The Company adopted the guidance as of March 31, 2020. The adoption of this guidance did not have an impact on the Company's consolidated financial statements. ASU No. 2019-12, Simplifying the Accounting for Income Taxes ("ASU 2019-12") In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740). ASU 2019-12 simplifies the accounting for income taxes by eliminating certain exceptions for investments, intraperiod allocations and interim calculations. The new guidance also simplifies aspects of the accounting for franchise taxes, enacted changes in tax laws or rates, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The amendments did not create new accounting requirements. The Company adopted the standard as of January 1, 2020. The adoption of this standard did not have a significant impact on 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 the standard as of January 1, 2020. The adoption of this standard did not have a significant impact on the Company's consolidated financial statements. ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350) ("ASU 2017-04") In January 2017, the FASB issued ASU 2017-04 which simplifies the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The amendment requires an entity to perform its annual, or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The Company adopted the standard as of January 1, 2020. The adoption of this standard did not have an impact on the Company's consolidated financial statements. 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 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. ASU 2016-13 became effective for the Company on January 1, 2020 and the adoption of this standard did not have a significant impact on the Company's consolidated financial statements. Accounting Standards Adopted in 2022 ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers , which will require companies to apply the definition of a performance obligation under ASC Topic 606, Revenue from Contracts with Customers, to recognize and measure contract assets and contract liabilities relating to contracts with customers that are acquired in a business combination. Under current GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded before the acquisition under ASC Topic 606. ASU No. 2021-08 is effective for the Company on January 1, 2023, however the Company elected to early adopt this ASU on January 1, 2022 and the Company will provide required disclosures for any future material transactions. ASU No. 2021-10, Government Assistance (Topic 832) In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832) , which requires business entities to disclose information about transactions with a government that are accounted for by applying a grant or contribution model by analogy (for example, IFRS guidance in IAS 20 or guidance on contributions for not-for-profit entities in ASC 958-605). For transactions in the scope of the new standard, business entities will need to provide information about the nature of the transaction, including significant terms and conditions, as well as the amounts and specific financial statement line items affected by the transaction. The Company adopted the new guidance on January 1, 2022 and it did not have a material impact on the Company's consolidated financial statements. The Company will provide the required disclosures for any future material transactions. Recently Issued But Not Yet Adopted Accounting Pronouncements ASU No. 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations In September 2022, the FASB issued ASU 2022-04, Liabilities—Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations , to enhance transparency about an entity’s use of supplier finance programs. ASU 2022-04 would require the buyer in a supplier finance program to disclose (a) information about the key terms of the program, (b) the amount outstanding that remains unpaid by the buyer as of the end of the period, (c) a rollforward of such amounts during each annual period, and (d) a description of where in the financial statements outstanding amounts are being presented. ASU 2022-04 is effective for the Company on January 1, 2023, except for the amendment on rollforward information which will be effective for the Company on January 1, 2024. Early adoption is permitted. The Company will provide any necessary disclosures upon adoption.

Earnings Per Share [Abstract]
Earnings Per Share	NET INCOME PER SHARE Basic net income per common share attributable to Altice USA stockholders is computed by dividing net income attributable to Altice USA stockholders by the weighted average number of common shares outstanding during the period. Diluted income per common share attributable to Altice USA stockholders reflects the dilutive effects of stock options, restricted stock and restricted stock units. For awards that are performance based, the diluted effect is reflected upon the achievement of the performance criteria. The following table presents a reconciliation of weighted average shares used in the calculations of the basic and diluted net income per share attributable to Altice USA stockholders: Years Ended December 31, 2022 2021 2020 (in thousands) Basic weighted average shares outstanding 453,244 458,311 581,057 Effect of dilution: Stock options — 3,972 2,617 Restricted stock 38 11 15 Restricted stock units — 1 — Diluted weighted average shares outstanding 453,282 462,295 583,689 Weighted average shares excluded from diluted weighted average shares outstanding: Anti-dilutive shares 57,961 15,856 25,768 Performance stock units and restricted stock whose performance metrics have not been achieved 7,309 8,557 8,308 Net income per membership unit for CSC Holdings is not presented since CSC Holdings is a limited liability company and a wholly-owned subsidiary of Altice USA.

PROPERTY, PLANT AND EQUIPMENT	PROPERTY, PLANT AND EQUIPMENTCosts incurred in the construction of the Company's cable systems, including line extensions to, and upgrade of, the Company's hybrid fiber/coaxial infrastructure and construction of the parallel fiber-to-the-home ("FTTH") infrastructure, are capitalized. This includes headend facilities and initial placement of the feeder cable to connect a customer that had not been previously connected. These costs consist of materials, subcontractor labor, direct consulting fees, and internal labor and related costs associated with the construction activities (including interest related to FTTH construction). The internal costs that are capitalized consist of salaries and benefits of the Company's employees and the portion of facility costs, including rent, taxes, insurance and utilities that supports the construction activities. These costs are depreciated over the estimated life of the plant (10 to 25 years) and headend facilities (5 to 25 years). Costs of operating the plant and the technical facilities, including repairs and maintenance, are expensed as incurred. Costs associated with the initial deployment of new customer premise equipment ("CPE") necessary to provide broadband, video and telephony services are also capitalized. These costs include materials, subcontractor labor, internal labor, and other related costs associated with the connection activities. The departmental activities supporting the connection process are tracked through specific metrics, and the portion of departmental costs that is capitalized is determined through a time weighted activity allocation of costs incurred based on time studies used to estimate the average time spent on each activity. These installation costs are amortized over the estimated useful lives of the CPE necessary to provide broadband, video and telephony services. The portion of departmental costs related to disconnecting services and removing CPE from a customer, costs related to connecting CPE that has been previously connected to the network, and repairs and maintenance are expensed as incurred. The estimated useful lives assigned to our property, plant and equipment are reviewed on an annual basis or more frequently if circumstances warrant and such lives are revised to the extent necessary due to changing facts and circumstances. Any changes in estimated useful lives are reflected prospectively. Property, plant and equipment (including equipment under finance leases) consist of the following assets, which are depreciated or amortized on a straight-line basis over the estimated useful lives shown below: December 31, Estimated 2022 2021 Customer premise equipment $ 2,134,561 $ 1,991,746 3 to 5 years Headends and related equipment 2,493,208 2,327,642 5 to 25 years Infrastructure 7,711,815 6,606,817 5 to 25 years Equipment and software 1,434,742 1,362,770 3 to 10 years Construction in progress (including materials and supplies) 499,598 291,611 Furniture and fixtures 81,518 74,481 5 to 8 years Transportation equipment 145,413 145,531 5 to 10 years Buildings and building improvements 550,884 506,363 10 to 40 years Leasehold improvements 185,645 127,565 Term of lease Land 48,793 48,793 15,286,177 13,483,319 Less accumulated depreciation and amortization (7,785,397) (7,142,852) $ 7,500,780 $ 6,340,467 For the years ended December 31, 2022, 2021 and 2020, the Company capitalized certain costs aggregating $138,845, $145,837 and $134,857, respectively, related to the acquisition and development of internal use software, which are included in the table above. Depreciation expense on property, plant and equipment (including finance leases) for the years ended December 31, 2022, 2021 and 2020 amounted to $1,218,365, $1,145,316 and $1,344,732, respectively.

LEASES

LEASES	12 Months Ended

Leases [Abstract]
LEASES	LEASESThe Company's operating leases are comprised primarily of facility leases and finance leases are comprised primarily of vehicle and equipment leases. The Company determines if an arrangement is a lease at inception and lease assets and liabilities are recognized upon commencement of the lease based on the present value of the future minimum lease payments over the lease term. Lease assets and liabilities are not recorded for leases with an initial term of one year or less. The Company generally uses its incremental borrowing rate as the discount rate for leases, unless an interest rate is implicitly stated in the lease. The lease term will include options to extend the lease when it is reasonably certain that the Company will exercise that option. Balance sheet information related to our leases is presented below: Balance Sheet location December 31, 2022 2021 Operating leases: Right-of-use lease assets Right-of-use operating lease assets $ 250,601 $ 222,124 Right-of-use lease liability, current Other current liabilities 38,740 38,545 Right-of-use lease liability, long-term Right-of-use operating lease liability 260,237 237,226 Finance leases: Right-of-use lease assets Property, plant and equipment 332,217 272,948 Right-of-use lease liability, current Current portion of long-term debt 129,657 109,204 Right-of-use lease liability, long-term Long-term debt 114,938 109,531 The following provides details of the Company's lease expense: Years Ended December 31, 2022 2021 Operating lease expense, net $ 58,124 $ 56,951 Finance lease expense: Amortization of assets 86,455 56,945 Interest on lease liabilities 11,332 8,966 Total finance lease expense 97,787 65,911 $ 155,911 $ 122,862 Other information related to leases is presented below: As of December 31, 2022 2021 Right-of-use assets acquired in exchange for operating lease obligations $ 74,063 $ 26,008 Cash Paid For Amounts Included In Measurement of Liabilities: Operating cash flows from finance leases 11,332 8,966 Operating cash flows from operating leases 65,879 61,443 Weighted Average Remaining Lease Term: Operating leases 8.1 years 8.4 years Finance leases 2.0 years 2.2 years Weighted Average Discount Rate: Operating leases 5.63 % 5.51 % Finance leases 5.49 % 4.63 % The minimum future annual payments under non-cancellable leases during the next five years and thereafter, at rates now in force, are as follows: Finance leases Operating leases 2023 $ 139,462 $ 48,284 2024 89,098 54,435 2025 29,126 46,806 2026 934 43,155 2027 716 40,556 Thereafter 335 144,837 Total future minimum lease payments, undiscounted 259,671 378,073 Less: Imputed interest (15,076) (79,096) Present value of future minimum lease payments $ 244,595 $ 298,977

(g) Approximately $1,299,158 of the Term Loan B and approximately $700,174 of the Incremental Term Loan B-3 were repaid with proceeds from the Incremental Term Loan B-6 entered into by the Company in December 2022. CSC Holdings Credit Facilities For financing purposes, the Company has two debt silos: CSC Holdings and Lightpath. The CSC Holdings silo is structured as a restricted group (the "Restricted Group") and an unrestricted group, which includes certain designated subsidiaries and investments (the "Unrestricted Group"). The Restricted Group is comprised of CSC Holdings and substantially all of its wholly-owned operating subsidiaries excluding Lightpath, a 50.01% owned subsidiary of the Company, which became an unrestricted subsidiary in September 2020. These Restricted Group subsidiaries are subject to the covenants and restrictions of the credit facility and indentures governing the notes issued by CSC Holdings. The Lightpath silo includes all of its operating subsidiaries which are subject to the covenants and restrictions of the credit facility and indentures governing the notes issued by Lightpath. See discussion below regarding the Lightpath debt financing. In October 2015, a wholly-owned subsidiary of Altice USA, which merged with and into CSC Holdings on June 21, 2016, entered into a senior secured credit facility, which currently provides U.S. dollar term loans currently in an aggregate principal amount of $3,000,000 ($1,535,842 outstanding at December 31, 2022) (the "CSC Term Loan Facility", and the term loans extended under the CSC Term Loan Facility, the "CSC Term Loans") and U.S. dollar revolving loan commitments in an aggregate principal amount of $2,475,000 ($1,575,000 outstanding at December 31, 2022) (the "CSC Revolving Credit Facility" and, together with the CSC Term Loan Facility, the "CSC Credit Facilities"), which are governed by a credit facilities agreement entered into by, inter alios, CSC Holdings certain lenders party thereto and JPMorgan Chase Bank, N.A. as administrative agent and security agent (as amended, restated, supplemented or otherwise modified from time to time, the "CSC Credit Facilities Agreement"). The Term Loan B is comprised of eurodollar borrowings or alternate base rate borrowings, and bears interest at a rate per annum equal to the adjusted LIBOR or the alternate base rate, as applicable, plus the applicable margin, where the applicable margin is (i) with respect to any alternate base rate loan, 1.25% per annum and (ii) with respect to any eurodollar loan, 2.25% per annum. The Company is required to make scheduled quarterly payments equal to 0.25% of the principal amount of the Term Loan B, beginning with the fiscal quarter ended September 30, 2017, with the remaining balance scheduled to be paid on July 17, 2025. In October 2019, CSC Holdings entered into a $3,000,000 ($2,917,500 outstanding at December 31, 2022), incremental term loan facility ("Incremental Term Loan B-5") under its existing credit facilities agreement, out of which $500,000 was available on a delayed draw basis. The Incremental Term Loan B-5 matures on April 15, 2027 and was issued at par. The Incremental Term Loan B-5 may be comprised of eurodollar borrowings or alternative base rate borrowings, and will bear interest at a rate per annum equal to the Adjusted LIBOR or the alternate base rate, as applicable, plus the applicable margin, where the applicable margin is (i) with respect to any alternate base rate loan, 1.50% per annum and (ii) with respect to any eurodollar loan, 2.50% per annum. The Company is required to make scheduled quarterly payments equal to 0.25% (or $7,500) of the principal amount of the Incremental Term Loan B-5, beginning with the fiscal quarter ended June 30, 2020. On July 13, 2022, CSC Holdings entered into an amendment (the "Twelfth Amendment") under its existing credit facilities agreement. The Twelfth Amendment provides for, among other things, an extended maturity on the CSC Revolving Credit Facility until the date that is the earlier of (i) July 13, 2027 and (ii) April 17, 2025 if, as of such date, any Term Loan B borrowings are still outstanding, unless the Term Loan B maturity date has been extended to a date falling after July 13, 2027. Interest on borrowings under the Twelfth Amendment are calculated based on the Term Secured Overnight Financing Rate ("SOFR") or alternative base rate borrowings, at a rate per annum equal to the Term SOFR rate (plus a Term SOFR credit adjustment spread of 0.10%) or the alternate base rate, as applicable, plus the applicable margin, where the applicable margin is (i) with respect to any alternate base rate loan, 1.25% per annum and (ii) with respect to any Term SOFR loan, 2.25% per annum. On December 19, 2022, CSC Holdings entered into the thirteenth amendment under its existing credit facilities agreement (the "Thirteenth Amendment" or "Incremental Term Loan B-6"). The Incremental Term Loan B-6 provides for, among other things, new refinancing term loan commitments in an aggregate principal amount of $2,001,942 issued with an original issue discount of 200 basis points, with an extended maturity until the date that is the earlier of (i) January 15, 2028 and (ii) April 15, 2027 if, as of such date, any Incremental Term Loan B-5 borrowings are still outstanding, unless the Incremental Term Loan B-5 maturity date has been extended to a date falling after January 15, 2028. Interest on the Incremental Term Loan B-6 will be calculated at a rate per annum equal to the Term SOFR rate or the alternate base rate, as applicable, plus the applicable margin, where the applicable margin is (i) with respect to any alternate base rate loan, 3.50% per annum and (ii) with respect to any Term SOFR loan, 4.50% per annum. The proceeds from the Incremental Term Loan B-6 were used to refinance (including by way of cashless roll) a portion of the Company's Term Loan B and Incremental Term Loan B-3. The Company is required to make scheduled quarterly payments equal to 0.25% (or $5,004) of the principal amount of the Incremental Term Loan B-6, beginning with the fiscal quarter ended June 30, 2023. During the year ended December 31, 2022, CSC Holdings borrowed $2,315,000 under its revolving credit facility and repaid $1,640,000 of amounts outstanding under the revolving credit facility. A portion of these borrowings were used to redeem at maturity $649,024 aggregate outstanding principal amount of CSC Holdings 5.875% senior notes due September 2022. The CSC Credit Facilities Agreement requires the prepayment of outstanding CSC Term Loans, subject to certain exceptions and deductions, with (i) 100% of the net cash proceeds of certain asset sales, subject to reinvestment rights and certain other exceptions; and (ii) on a pari ratable share (based on the outstanding principal amount of the Term Loans divided by the sum of the outstanding principal amount of all pari passu indebtedness and the Term Loans) of 50% of annual excess cash flow, which will be reduced to 0% if the consolidated net senior secured leverage ratio of CSC Holdings is less than or equal to 4.5 to 1. The obligations under the CSC Credit Facilities are guaranteed by each restricted subsidiary of CSC Holdings (other than CSC TKR, LLC and its subsidiaries, Lightpath, and certain excluded subsidiaries) (the "Initial Guarantors") and, subject to certain limitations, will be guaranteed by each future material wholly-owned restricted subsidiary of CSC Holdings. The obligations under the CSC Credit Facilities (including any guarantees thereof) are secured on a first priority basis, subject to any liens permitted by the Credit Facilities, by capital stock held by CSC Holdings or any guarantor in certain subsidiaries of CSC Holdings, subject to certain exclusions and limitations. The CSC Credit Facilities Agreement includes certain negative covenants which, among other things and subject to certain significant exceptions and qualifications, limit CSC Holdings' ability and the ability of its restricted subsidiaries to: (i) incur or guarantee additional indebtedness, (ii) make investments, (iii) create liens, (iv) sell assets and subsidiary stock, (v) pay dividends or make other distributions or repurchase or redeem our capital stock or subordinated debt, (vi) engage in certain transactions with affiliates, (vii) enter into agreements that restrict the payment of dividends by subsidiaries or the repayment of intercompany loans and advances; and (viii) engage in mergers or consolidations. In addition, the CSC Revolving Credit Facility includes a financial maintenance covenant solely for the benefit of the lenders under the CSC Revolving Credit Facility consisting of a maximum consolidated net senior secured leverage ratio of CSC Holdings and its restricted subsidiaries of 5.0 to 1.0. The financial covenant will be tested on the last day of any fiscal quarter, but only if on such day there are outstanding borrowings, as defined, under the CSC Revolving Credit Facility. The CSC Credit Facilities Agreement also contains certain customary representations and warranties, affirmative covenants and events of default (including, among others, an event of default upon a change of control). If an event of default occurs, the lenders under the CSC Credit Facilities will be entitled to take various actions, including the acceleration of amounts due under the CSC Credit Facilities and all actions permitted to be taken by a secured creditor. Issuances of Senior Guaranteed Notes and Senior Notes In May 2021, CSC Holdings issued $1,500,000 in aggregate principal amount of senior guaranteed notes that bear interest at a rate of 4.500% and mature on November 15, 2031 and $500,000 in aggregate principal amount of senior notes that bear interest at a rate of 5.000% which also mature on November 15, 2031. The net proceeds from the sale of these notes were used to early redeem the $1,498,806 aggregate principal amount of CSC Holdings' 5.500% senior guaranteed notes due May 15, 2026, plus pay accrued interest and the associated premium related to the early redemption of these notes. The remaining proceeds were used for general corporate purposes, including repayment of borrowings under the CSC Holdings revolving credit facility and share repurchases. The indentures under which the Senior Guaranteed Notes and Senior Notes were issued contain certain customary covenants and agreements, including limitations on the ability of CSC Holdings and its restricted subsidiaries to (i) incur or guarantee additional indebtedness, (ii) make investments or other restricted payments, (iii) create liens, (iv) sell assets and subsidiary stock, (v) pay dividends or make other distributions or repurchase or redeem our capital stock or subordinated debt, (vi) engage in certain transactions with affiliates, (vii) enter into agreements that restrict the payment of dividends by subsidiaries or the repayment of intercompany loans and advances, and (viii) engage in mergers or consolidations, in each case subject to certain exceptions. The indentures also contain certain customary events of default. If an event of default occurs, the obligations under the notes may be accelerated. Subject to customary conditions, the Company may redeem some or all of the notes at the redemption price set forth in the relevant indenture, plus accrued and unpaid interest, plus a specified "make-whole" premium (in the event the notes are redeemed prior to a certain specified time set forth in the indentures). Lightpath Credit Facility On September 29, 2020, Lightpath entered into a credit agreement between, inter alios, certain lenders party thereto and Goldman Sachs Bank USA, as administrative agent, and Deutsche Bank Trust Company Americas, as collateral agent, (the "Lightpath Credit Agreement") which provides for, among other things, (i) a term loan in an aggregate principal amount of $600,000 (the “Lightpath Term Loan Facility”) at a price of 99.5% of the aggregate principal amount, which was drawn on November 30, 2020, and (ii) revolving loan commitments in an aggregate principal amount of $100,000 (the “Lightpath Revolving Credit Facility"). As of December 31, 2022 and 2021, there were no borrowings outstanding under the Lightpath Revolving Credit Facility. The Company is required to make scheduled quarterly payments equal to 0.25% (or $1,500) of the principal amount of the Lightpath Term Loan Facility, beginning with the fiscal quarter ended March 31, 2021. The loans made pursuant to the Lightpath Credit Agreement are comprised of eurodollar borrowings or alternative base rate borrowings, and bear interest at a rate per annum equal to the adjusted LIBOR rate or the alternate base rate, as applicable, plus the applicable margin, where the applicable margin is (i) with respect to any alternate base rate loan, 2.25% per annum and (ii) with respect to any eurodollar loan, 3.25% per annum. As of December 31, 2022, CSC Holdings and Lightpath were in compliance with applicable financial covenants under their respective credit facilities and with applicable financial covenants under each respective indenture by which the senior guaranteed notes, senior secured notes and senior notes were issued.

DERIVATIVE CONTRACTS AND COLLAT

DERIVATIVE CONTRACTS AND COLLATERALIZED INDEBTEDNESS	12 Months Ended
	Dec. 31, 2022
Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE CONTRACTS AND COLLATERALIZED INDEBTEDNESS	DERIVATIVE CONTRACTS AND COLLATERALIZED INDEBTEDNESS Prepaid Forward Contracts The Company has entered into various transactions to limit the exposure against equity price risk on its shares of Comcast Corporation ("Comcast") common stock. The Company has monetized all of its stock holdings in Comcast through the execution of prepaid forward contracts, collateralized by an equivalent amount of the respective underlying stock. At maturity, the contracts provide for the option to deliver cash or shares of Comcast stock with a value determined by reference to the applicable stock price at maturity. These contracts, at maturity, are expected to offset declines in the fair value of these securities below the hedge price per share while allowing the Company to retain upside appreciation from the hedge price per share to the relevant cap price. The Company received cash proceeds upon execution of the prepaid forward contracts discussed above which has been reflected as collateralized indebtedness in the accompanying consolidated balance sheets. In addition, the Company separately accounts for the equity derivative component of the prepaid forward contracts. These equity derivatives have not been designated as hedges for accounting purposes. Therefore, the net fair values of the equity derivatives have been reflected in the accompanying consolidated balance sheets as an asset or liability and the net increases or decreases in the fair value of the equity derivative component of the prepaid forward contracts are included in gain (loss) on derivative contracts in the accompanying consolidated statements of operations. All of the Company's monetization transactions are obligations of its wholly-owned subsidiaries that are not part of the Restricted Group; however, CSC Holdings has provided guarantees of the subsidiaries' ongoing contract payment expense obligations and potential payments that could be due as a result of an early termination event (as defined in the agreements). If any one of these contracts was terminated prior to its scheduled maturity date, the Company would be obligated to repay the fair value of the collateralized indebtedness less the sum of the fair values of the underlying stock and equity collar, calculated at the termination date. As of December 31, 2022, the Company did not have an early termination shortfall relating to any of these contracts. The Company monitors the financial institutions that are counterparties to its equity derivative contracts. All of the counterparties to such transactions carry investment grade credit ratings as of December 31, 2022. In January 2023, the Company settled its outstanding collateralized indebtedness by delivering the Comcast shares it held and the related equity derivative contracts which resulted in the Company receiving net cash of approximately $50,500. Interest Rate Swap Contracts To manage interest rate risk, we have from time to time entered into interest rate swap contracts to adjust the proportion of total debt that is subject to variable and fixed interest rates. Such contracts effectively fix the borrowing rates on floating rate debt to provide an economic hedge against the risk of rising rates and/or effectively convert fixed rate borrowings to variable rates to permit the Company to realize lower interest expense in a declining interest rate environment. We monitor the financial institutions that are counterparties to our interest rate swap contracts and we only enter into interest rate swap contracts with financial institutions that are rated investment grade.

FAIR VALUE MEASUREMENT

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENT The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity's pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels: • Level I - Quoted prices for identical instruments in active markets. • Level II - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level III - Instruments whose significant value drivers are unobservable. The following table presents the Company's financial assets and financial liabilities that are measured at fair value on a recurring basis and their classification under the fair value hierarchy: Fair Value December 31, 2022 2021 Assets: Money market funds Level I $ 141,137 $ 100,015 Investment securities pledged as collateral Level I 1,502,145 2,161,937 Prepaid forward contracts Level II 263,873 — Interest rate swap contracts Level II 185,622 2,993 Liabilities: Prepaid forward contracts Level II — 161,942 Interest rate swap contracts Level II — 118,432 Contingent consideration related to acquisition Level III 8,383 — The Company's money market funds which are classified as cash equivalents and investment securities pledged as collateral are classified within Level I of the fair value hierarchy because they are valued using quoted market prices. The Company's derivative contracts and liabilities under derivative contracts on the Company's consolidated balance sheets are valued using market-based inputs to valuation models. These valuation models require a variety of inputs, including contractual terms, market prices, yield curves, and measures of volatility. When appropriate, valuations are adjusted for various factors such as liquidity, bid/offer spreads and credit risk considerations. Such adjustments are generally based on available market evidence. Since model inputs can generally be verified and do not involve significant management judgment, the Company has concluded that these instruments should be classified within Level II of the fair value hierarchy. The fair value of the contingent consideration as of December 31, 2022 related to an acquisition in the third quarter of 2022 was determined using a probability assessment of the contingent payment. Fair Value of Financial Instruments The following methods and assumptions were used to estimate fair value of each class of financial instruments for which it is practicable to estimate: Credit Facility Debt, Collateralized Indebtedness, Senior Notes, Senior Guaranteed Notes, Senior Secured Notes, Notes Payable and Supply Chain Financing The fair values of each of the Company's debt instruments are based on quoted market prices for the same or similar issues or on the current rates offered to the Company for instruments of the same remaining maturities. The fair value of notes payable is based primarily on the present value of the remaining payments discounted at the borrowing cost. The carrying value of outstanding amounts related to supply chain financing agreements approximates the fair value due to their short-term maturity (less than one year). The carrying values, estimated fair values, and classification under the fair value hierarchy of the Company's financial instruments, excluding those that are carried at fair value in the accompanying consolidated balance sheets, are summarized below: December 31, 2022 December 31, 2021 Fair Value Carrying Estimated Carrying Estimated Credit facility debt Level II $ 9,063,495 $ 9,145,298 $ 8,495,611 $ 8,546,438 Collateralized indebtedness Level II 1,746,281 1,731,771 1,706,997 1,741,710 Senior guaranteed and senior secured notes Level II 8,081,489 6,154,075 8,077,372 8,180,813 Senior notes Level II 7,324,238 4,531,300 7,950,241 7,883,071 Notes payable and supply chain financing Level II 127,635 127,608 97,804 97,588 $ 26,343,138 $ 21,690,052 $ 26,328,025 $ 26,449,620 (a) Amounts are net of unamortized deferred financing costs and discounts/premiums.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXESAltice USA files a federal consolidated and certain state combined income tax returns with its 80% or more owned subsidiaries. CSC Holdings and its subsidiaries are included in the consolidated federal income tax returns of Altice USA. The income tax provision for CSC Holdings is determined on a stand-alone basis for all periods presented as if CSC Holdings filed separate consolidated income tax returns. In accordance with a tax sharing agreement between CSC Holdings and Altice USA, CSC Holdings has an obligation to Altice USA for its stand-alone current tax liability as if it filed separate income tax returns. Income tax expense for the years ended December 31, 2022, 2021 and 2020 consist of the following components: Altice USA CSC Holdings Years Ended December 31, Years Ended December 31, 2022 2021 2020 2022 2021 2020 Current expense (benefit): Federal $ 133,329 $ 168,397 $ — $ 133,329 $ 179,032 $ (55,044) State 81,076 56,211 65,804 88,068 56,211 82,238 Foreign 128 (3) — 128 (3) — 214,533 224,605 65,804 221,525 235,240 27,194 Deferred expense (benefit): Federal (43,797) 70,989 113,871 (43,797) 70,989 156,338 State 80,356 (30,108) (38,359) 69,676 (38,608) (55,121) Foreign (174) (180) — (174) (180) — 36,385 40,701 75,512 25,705 32,201 101,217 250,918 265,306 141,316 247,230 267,441 128,411 Tax expense (benefit) relating to uncertain tax positions 44,922 29,669 (1,568) 44,922 29,669 (1,568) Income tax expense $ 295,840 $ 294,975 $ 139,748 $ 292,152 $ 297,110 $ 126,843 The income tax expense attributable to operations differs from the amount derived by applying the statutory federal rate to pretax income principally due to the effect of the following items: Altice USA CSC Holdings Years Ended December 31, Years Ended December 31, 2022 2021 2020 2022 2021 2020 Federal tax expense at statutory rate $ 108,513 $ 274,240 $ 122,478 $ 108,513 $ 274,240 $ 122,363 State income taxes, net of federal impact 26,527 21,492 59,383 28,768 13,973 58,802 Changes in the valuation allowance 20,176 13,573 10,333 15,494 12,793 10,598 Change in New York state rate to measure deferred taxes, net of federal impact 112,117 — — 112,117 — — Other changes in the state rates used to measure deferred taxes, net of federal impact (9,603) (6,924) (46,768) (10,849) (7,125) (46,768) Tax expense (benefit) relating to uncertain tax positions 36,281 24,580 (1,568) 36,281 24,580 (1,568) Tax credits (3,544) (2,500) (17,205) (3,544) (2,500) (17,205) Excess tax deficiencies (benefits) related to share-based compensation including non-deductible carried unit plans 10,321 (2,602) (116) 10,321 (2,602) (116) Non-deductible officers compensation 4,916 7,201 6,715 4,916 7,201 6,715 Foreign losses of disregarded entities (6,352) — — (6,352) — — Other permanent differences — (35,256) — — (35,256) — Other non-deductible expenses (benefits) 1,588 1,483 1,340 1,588 1,483 (886) Other, net (5,100) (312) 5,156 (5,101) 10,323 (5,092) Income tax expense $ 295,840 $ 294,975 $ 139,748 $ 292,152 $ 297,110 $ 126,843 In December 2022, the New York State Division of Tax Appeals, via an Administrative Law Judge determination, published a decision in Charter Communications, Inc. versus New York State, which concluded that each corporation in a combined reporting group would have to separately qualify as a qualified emerging technology company (“QETC”) to use the preferential QETC tax rate. As the Company had been historically using the QETC rate at the combined reporting group level, it recorded a cumulative income tax expense of $157,300 that included both a revaluation of state deferred taxes and an increase to the Company's uncertain tax positions reserve for tax years 2017 through 2022 based on this published decision. In 2021, due to internal restructuring of i24NEWS and a permanent reduction in tax relating to the Opportunity Zones commitment (see note below), a permanent tax benefit of $35,256 was recognized. In 2020, the Company recorded a $17,205 benefit resulting from research and development tax credits for the years 2016 through 2019. In March 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. Included in the CARES Act, was a revision to IRC Sec 163(j) increasing the ATI (adjusted taxable income) limit of deductible interest from 30% to 50% for tax years 2019 and 2020. The additional deductible interest on the 2019 federal return was $176,539, tax-effected; as a result, the previously reported federal net operating loss carryforwards (“NOLs”) were increased by $176,539, resulting in a net zero tax impact for CSC Holdings and Altice USA. The tax effects of temporary differences which give rise to significant portions of deferred tax assets or liabilities and the corresponding valuation allowance are as follows: Altice USA CSC Holdings December 31, December 31, 2022 2021 2022 2021 Noncurrent NOLs, capital loss, and tax credit carry forwards (a) $ 117,995 $ 171,705 $ 86,547 $ 134,259 Compensation and benefit plans 97,115 63,870 97,115 63,870 Restructuring liability 2,079 2,208 2,079 2,208 Other liabilities 48,433 40,946 48,433 40,946 Research and experimental expenditures 22,292 — 22,292 — Liabilities under derivative contracts 315,861 475,970 315,861 475,970 Interest deferred for tax purposes 272,842 63,402 272,842 63,402 Operating lease liability 71,232 65,538 71,232 65,538 Deferred tax assets 947,849 883,639 916,401 846,193 Less: Valuation allowance (73,560) (53,384) (50,745) (35,251) Net deferred tax assets, noncurrent 874,289 830,255 865,656 810,942 Deferred tax liabilities: Fixed assets and intangibles (5,185,319) (4,955,405) (5,185,319) (4,955,405) Operating lease asset (58,360) (51,494) (58,360) (51,494) Investments (393,700) (559,919) (393,700) (559,919) Partnership investments (155,434) (143,908) (155,434) (143,908) Prepaid expenses (11,477) (13,042) (11,477) (13,042) Fair value adjustments related to debt and deferred financing costs (5,698) (11,985) (5,698) (11,985) Opportunity Zone tax deferral (145,608) (142,631) (145,608) (142,631) Deferred tax liability, noncurrent (5,955,596) (5,878,384) (5,955,596) (5,878,384) Total net deferred tax liabilities $ (5,081,307) $ (5,048,129) $ (5,089,940) $ (5,067,442) (a) Includes deferred tax assets of $354 as of December 31, 2022 that relate to the net operating losses of foreign subsidiaries which are presented under Other assets on the consolidated balance sheets. Under the Tax Cuts & Jobs Act (“TCJA”) enacted in December 2017, research and experimental expenditures are required to be capitalized and amortized for the tax years beginning after December 31, 2021. As a result, the Company has capitalized (net of amortization) $22,292 in 2022. As a result of the Company selling its 1% interest in Newsday LLC, as well as internal restructuring of i24NEWS in 2021, capital losses of $235,316 and $104,171, respectively, were recognized for tax purposes. In the fourth quarter of 2022, the Company carried back the net capital loss against the taxable capital gain generated in connection with the 49.99% sale of Lightpath in 2020. In addition, the Company received $48,645 in 2021 relating to a refund request for prior year AMT credits, including $12,161 claimed in 2020 due to the CARES Act acceleration of credits. Deferred tax assets have resulted primarily from the Company's future deductible temporary differences and NOLs. 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 asset will not 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. If such estimates and related assumptions change in the future, the Company may be required to record additional valuation allowances against its deferred tax assets, resulting in additional income tax expense in the Company's consolidated statements of operations. Management evaluates the realizability of the deferred tax assets and the need for additional valuation allowances quarterly. Due to the significant deferred tax liabilities associated with our fixed assets and intangibles, primarily due to the change in the 2017 TCJA, allowing 100% bonus depreciation on most fixed assets, as well as the continued taxable income adjustments associated with the deferred tax liabilities established under purchase accounting pursuant to the Cablevision and Cequel acquisitions in 2016, the future taxable income that will result from the reversal of existing taxable temporary differences for which deferred tax liabilities are recognized is sufficient to conclude it is more likely than not that the Company will realize all of its gross deferred tax assets, except those deferred tax assets against which a valuation allowance has been recorded which relate to certain state NOLs and the foreign NOLs in i24NEWS. In the normal course of business, the Company engages in transactions in which the income tax consequences may be uncertain. The Company's income tax returns are filed based on interpretation of tax laws and regulations. Such income tax returns are subject to examination by taxing authorities. For financial statement purposes, the Company only recognizes tax positions that it believes are more likely than not of being sustained. There is considerable judgment involved in determining whether positions taken or expected to be taken on the tax return are more likely than not of being sustained. Changes in the liabilities for uncertain tax positions are recognized in the interim period in which the positions are effectively settled or there is a change in factual circumstances. The following is the activity relating to the Company's liability for uncertain tax positions: Years Ended December 31, 2022 2021 2020 Balance at beginning of year $ 25,296 $ 1,301 $ 2,093 Increases (decreases) from prior period positions 871 (637) (792) Increases from current period positions 44,426 24,632 — Balance at end of year $ 70,593 $ 25,296 $ 1,301 Interest and penalties related to unrecognized tax benefits (“UTBs”) are included in our provision for income taxes. We recognized a net expense (benefit) for interest and penalties of $9,683, $6,159, and $(1,301) during the years ended December 31, 2022, 2021, and 2020, respectively. As of December 31, 2022 and 2021, accrued interest and penalties associated with UTBs were $16,789 and $7,106, respectively. The increase in interest and penalties for the year ended December 31, 2022 was primarily due to the addition of the QETC tax rate position (see note above). We are not expecting a material change in the reserve due to expiring statutes, audit activity, or tax payments in the next twelve months. If we were to prevail on all uncertain positions, the net effect would result in an income tax benefit of $56,398. The most significant jurisdictions in which the Company is required to file income tax returns include the states of New York, New Jersey, Connecticut, and the City of New York. The State and City of New York are presently auditing income tax returns for tax years 2012 through 2018 and 2015 through 2019, respectively. The State of New Jersey is presently auditing income tax returns for tax years 2014 through 2017, and for tax years 2019 and 2020. Management does not believe that the resolution of these ongoing income tax examinations will have a material adverse impact on the financial position of the Company.

Share-Based Payment Arrangement [Abstract]
SHARE-BASED COMPENSATION	SHARE-BASED COMPENSATION The following table presents share-based compensation expense and unrecognized compensation cost: Share-Based Compensation Unrecognized Compensation Cost 2022 2021 2020 Awards issued pursuant to 2017 LTIP: Stock Option Awards $ 86,307 $ 87,697 $ 98,380 $ 75,493 Performance Stock Units 10,220 8,675 14,395 28,603 Restricted Share Units 63,458 1,120 2,276 60,927 Carry Unit Awards — 804 10,036 — $ 159,985 $ 98,296 $ 125,087 $ 165,023 Long Term Incentive Plan In connection with Altice USA's IPO, the Company adopted the Altice USA 2017 Long Term Incentive Plan (the "2017 LTIP"). Under the 2017 LTIP, the Company may grant awards of options, restricted shares, restricted share units, stock appreciation rights, performance stock, performance stock units and other awards. Under the 2017 LTIP, awards may be granted to officers, employees and consultants of the Company or any of its affiliates. The 2017 LTIP is administered by Altice USA's Board of Directors (the "Board"), subject to the provision of the stockholders' agreement. The Board has delegated its authority to the Company's Compensation Committee. The Compensation Committee has the full power and authority to, among other things, select eligible participants, to grant awards in accordance with the 2017 LTIP, to determine the number of shares subject to each award or the cash amount payable in connection with an award and determine the terms and conditions of each award. In November 2018, the Board and the Company's stockholders holding a majority of the voting power of its capital stock approved an amendment to the 2017 LTIP, which increased the maximum aggregate number of shares that may be issued for all purposes under the Plan to 19,879,291. In June 2020, stockholders of the Company approved an increase to the number of shares authorized for issuance under the 2017 LTIP by 35,000,000 shares to 54,879,291 and approved the extension of the term to June 10, 2030. In June 2022, stockholders of the Company approved an increase to the number of shares authorized for issuance under the 2017 LTIP, as amended, by 35,000,000 shares to 89,879,291 shares. The Board has the authority to amend, suspend, or terminate the 2017 LTIP. No amendment, suspension or termination will be effective without the approval of the Company's stockholders if such approval is required under applicable laws, rules and regulations. Stock Option Awards Options outstanding under the 2017 LTIP Plan either (i) cliff vest on the third anniversary of the date of grant, (ii) vest over 3 years in annual increments of 33-1/3%, or (iii) vest over 4 years, where 50% vest on the second anniversary, 25% on the third anniversary and 25% on the fourth anniversary of the date of grant. The option awards generally are subject to continued employment with the Company, and expire 10 years from the date of grant. Performance based option awards vest upon achievement of performance criteria. The following table summarizes activity related to stock options granted to Company employees: Shares Under Option Weighted Average Weighted Average Remaining Time Aggregate Intrinsic Balance at December 31, 2019 14,083,741 $ 19.12 8.74 $ 112,915 Granted 26,569,892 28.41 Exercised (824,227) 17.46 Forfeited (2,767,260) 23.05 Balance at December 31, 2020 37,062,146 25.52 8.69 457,608 Granted 18,192,257 16.87 Exercised (1,368,156) 17.47 Forfeited and Cancelled (2,887,431) 28.02 Balance at December 31, 2021 50,998,816 22.51 8.29 6,801 Granted 7,888,472 9.30 Forfeited and Cancelled (7,811,613) 23.84 Balance at December 31, 2022 51,075,675 $ 20.27 7.73 $ 184 Options exercisable at December 31, 2022 29,446,269 $ 23.26 6.81 $ — (a) The aggregate intrinsic value is calculated as the difference between the exercise price and the closing price of Altice USA's Class A common stock at the respective date. As of December 31, 2022, the total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of approximately 2.24 years. The Company calculated the fair value of each option award on the date of grant using the Black-Scholes valuation model. The Company's computation of expected life was determined based on the simplified method (the average of the vesting period and option term) due to the Company's lack of recent historical data for similar awards. The interest rate for periods within the contractual life of the stock option was based on interest yields for U.S. Treasury instruments in effect at the time of grant. The Company's computation of expected volatility was based on historical volatility of its common stock and the expected volatility of comparable publicly-traded companies who granted options that had similar expected lives. The weighted-average fair values of stock option awards granted during the years ended December 31, 2022, 2021 and 2020 were $3.76, $6.42 and $7.82, respectively. The following weighted-average assumptions were used to calculate these fair values: Years Ended December 31, 2022 2021 2020 Risk-free interest rate 3.42% 1.36% 1.43% Expected life (in years) 6.24 6.02 6.38 Dividend yield —% —% —% Volatility 41.79% 35.80% 28.53% In January 2023, the Company commenced a stock option exchange program (the “Exchange Offer”) to cancel certain stock options granted with a per share exercise price greater than $6.00, held by certain eligible individuals who are current employees of the Company in exchange for restricted stock units (“RSU”) and deferred cash-denominated awards (“DCA”) at the exchange ratio of one RSU and $10 of DCAs for every seven eligible options in the Exchange Offer. Based on the terms of the Exchange Offer, if all eligible options are exchanged, (i) options to purchase 28,943,193 shares of our Class A common stock will be surrendered and cancelled; and (ii) 4,134,306 restricted stock units and $41,349 of deferred cash-denominated awards will be granted. The exchange of eligible options for RSUs will be accounted for as a modification of stock-based compensation awards. Accordingly, the Company expects to recognize the unamortized compensation cost of the surrendered eligible options, as well as any incremental compensation cost of the replacement awards granted in the Exchange Offer. Performance Stock Units In January 2020, certain employees of the Company were granted performance stock units ("PSUs"). Each PSU gives the employee the right to receive one share of Altice USA class A common stock, upon achievement of a specified stock price hurdle. The PSUs will be forfeited if the applicable performance measure is not achieved prior to January 29, 2026 or if the employee does not continue to provide services to the Company through the achievement date of the applicable performance measure.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments Future cash payments and commitments required under arrangements pursuant to contracts entered into by the Company in the normal course of business as of December 31, 2022 are as follows: Payments Due by Period Total Year 1 Years 2-3 Years 4-5 More than Off balance sheet arrangements: Purchase obligations (a) $ 7,892,430 $ 2,976,753 $ 4,067,055 $ 840,486 $ 8,136 Guarantees (b) 75,318 62,703 12,615 — — Letters of credit (c) 130,994 1,513 720 — 128,761 Total $ 8,098,742 $ 3,040,969 $ 4,080,390 $ 840,486 $ 136,897 (a) Purchase obligations primarily include contractual commitments with various programming vendors to provide video services to customers and minimum purchase obligations to purchase goods or services, including contracts to acquire handsets and other equipment. Future fees payable under contracts with programming vendors are based on numerous factors, including the number of customers receiving the programming. Amounts reflected above related to programming agreements are based on the number of customers receiving the programming as of December 31, 2022 multiplied by the per customer rates or the stated annual fee, as applicable, contained in the executed agreements in effect as of December 31, 2022. (b) Includes franchise and performance surety bonds primarily for the Company's cable television systems. (c) Represent letters of credit guaranteeing performance to municipalities and public utilities and payment of insurance premiums. Payments due by period for these arrangements represent the year in which the commitment expires although payments under these arrangements are required only in the event of nonperformance. The table above does not include obligations for payments required to be made under multi-year franchise agreements based on a percentage of revenues generated from video service per year. Many of the Company's franchise agreements and utility pole leases require the Company to remove its cable wires and other equipment upon termination of the respective agreements. The Company has concluded that the fair value of these asset retirement obligations cannot be reasonably estimated since the range of potential settlement dates is not determinable. The table above does not include obligations for rent related to utility poles used in our operations. The Company's pole rental agreements are for varying terms, and management anticipates renewals as they expire. Rent expense incurred for pole rental attachments for the years ended December 31, 2022, 2021 and 2020 was $40,277, $37,545, and $36,364, respectively. Legal Matters On November 6, 2018, Sprint Communications Company L.P ("Sprint") filed a complaint in the U.S. District Court for the District of Delaware alleging that the Company infringes Sprint’s patents purportedly by providing Voice over Internet Protocol ("VoIP") services. The lawsuit is part of a pattern of litigation that was initiated as far back as 2005 by Sprint against numerous broadband and telecommunications providers, which has resulted in judgments and settlements of significant value for Sprint. Sprint and the Company have reached a settlement of the foregoing suit for $112,500. The Company paid $65,000 to T-Mobile, the successor-in-interest to Sprint as of December 31, 2022, and the balance of $47,500 is payable on or before June 30, 2024. The Company is evaluating indemnity claims against certain suppliers in connection with this matter. On December 14, 2022, BMG Rights Management (US) LLC, UMG Recordings, Inc., Capitol Records, LLC, Concord Music Group, Inc., and Concord Bicycle Assets, LLC (collectively, “BMG” or “Plaintiffs”) filed a complaint in the U.S. District Court for the Eastern District of Texas, alleging that certain of the Company’s Internet subscribers directly infringed over 7,700 of Plaintiffs’ copyrighted works. Plaintiffs seek to hold the Company liable for claims of contributory infringement of copyright and vicarious copyright infringement. The Company intends to vigorously defend these claims.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended

Entity Information [Line Items]
Revenue Recognition	Revenue Recognition Residential Services The Company derives revenue through monthly charges to residential customers of its broadband, video, and telephony services, including installation services. In addition, the Company derives revenue from digital video recorder ("DVR"), video-on-demand ("VOD"), pay-per-view, and home shopping commissions which are reflected in "Residential video" revenues. The Company recognizes broadband, video, and telephony revenues as the services are provided to a customer on a monthly basis. Each service is accounted for as a distinct performance obligation. Revenue from the sale of bundled services at a discounted rate is allocated to each product based on the standalone selling price of each performance obligation within the bundled offer. The standalone selling price requires judgment and is typically determined based on the current prices at which the separate services are sold by the Company. Installation revenue for the Company's residential services is deferred and recognized over the benefit period, which is estimated to be less than one year. The estimated benefit period takes into account both quantitative and qualitative factors including the significance of average installation fees to total recurring revenue per customer. The Company is assessed non-income related taxes by governmental authorities, including franchising authorities (generally under multi-year agreements), and collects such taxes from its customers. In instances where the tax is being assessed directly on the Company, amounts paid to the governmental authorities are recorded as programming and other direct costs and amounts received from the customers are recorded as revenue. For the years ended December 31, 2022, 2021 and 2020, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $232,795, $257,364 and $257,405, respectively. Business and Wholesale Revenue The Company derives revenue from the sale of products and services to both large enterprise and small and medium-sized business ("SMB") customers, including broadband, telephony, networking, and video services reflected in "Business services and wholesale" revenues. The Company's business services also include Ethernet, data transport, and IP-based virtual private networks. The Company also provides managed services to businesses, including hosted telephony services (cloud based SIP-based private branch exchange), managed WiFi, managed desktop and server backup and managed collaboration services including audio and web conferencing. The Company also offers fiber-to-the-tower services to wireless carriers for cell tower backhaul, which enables wireline communications service providers to connect to customers that their own networks do not reach. The Company recognizes revenues for these services as the services are provided to a customer on a monthly basis. Substantially all of our SMB customers are billed monthly and large enterprise customers are billed in accordance with the terms of their contracts which is typically on a monthly basis. Contracts with large enterprise customers typically range from three News and Advertising Revenue As part of the agreements under which the Company acquires video programming, the Company typically receives an allocation of scheduled advertising time during such programming into which the Company's cable systems can insert commercials. In several of the markets in which the Company operates, it has entered into agreements commonly referred to as interconnects with other cable operators to jointly sell local advertising. In some of these markets, the Company represents the advertising sales efforts of other cable operators; in other markets, other cable operators represent the Company. The Company also offers customers the opportunity to advertise on digital platforms. Advertising revenues are recognized when the advertising is distributed. For 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 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. Revenue earned from the data-driven, audience-based advertising solutions using advanced analytics tools is recognized when services are provided. Affiliation fee revenue derived by our news business is recognized as the programming services are provided. Mobile Revenue The Company has a mobile service providing data, talk and text to consumers in or near our service areas. Customers can purchase or finance a variety of mobile devices. Revenue is recognized from the sale of equipment upon delivery and acceptance by the customer. Customers are billed monthly for access to and usage of our mobile services. The Company recognizes mobile service revenue as the services are provided to the customers. Other Revenue Revenues derived from other sources are recognized when services are provided or events occur. Customer Contract Costs Incremental costs incurred in obtaining a contract with a customer are deferred and recorded as an asset if the period of benefit is expected to be greater than one year. Sales commissions for enterprise customers are deferred and amortized over the average contract term. As the amortization period for sales commission expenses related to residential and SMB customers is less than one year, the Company is utilizing the practical expedient and is recognizing the costs when incurred. The costs of fulfilling a contract with a customer are deferred and recorded as an asset if they generate or enhance resources of the Company that will be used in satisfying future performance obligations and are expected to be recovered. Installation costs related to residential and SMB customers that are not capitalized as part of the initial deployment of new customer premise equipment are expensed as incurred pursuant to industry-specific guidance. Deferred enterprise sales commission costs are included in other current and noncurrent assets in the consolidated balance sheet and totaled $17,511 and $17,669 as of December 31, 2022 and 2021, respectively. A significant portion of our revenue is derived from residential and SMB customer contracts which are month-to month. 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. Contracts with enterprise customers generally range from three years to five years, and services may only be terminated in accordance with the contractual terms. Multiple-Element Transactions In the normal course of business, the Company may enter 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 contemporaneously with the purchase of a product or service, from a single counterparty. The Company's policy for accounting for each transaction negotiated contemporaneously is to record each deliverable of the transaction based on its best estimate of selling price in a manner consistent with that used to determine the price to sell each deliverable on a standalone basis. In determining the fair value of the respective deliverable, the Company utilizes historical transactions, quoted market prices (as available), or comparable transactions.
Technical and Operating Expenses and Programming Costs	Programming and Other Direct Costs Costs of revenue related to delivery of services and goods are classified as "programming and other direct costs" in the accompanying consolidated statements of operations. Programming Costs Programming expenses related to the Company's video service represent fees paid to programming distributors to license the programming distributed to video customers. This programming is acquired generally under multi-year distribution agreements, with rates usually based on the number of customers that receive the programming. If there are periods when an existing distribution agreement has expired and the parties have not finalized negotiations of either a renewal of that agreement or a new agreement for certain periods of time, the Company continues to carry and pay for these services until execution of definitive replacement agreements or renewals. The amount of programming expense recorded during the interim period is based on the Company's estimates of the ultimate contractual agreement expected to be reached, which is based on several factors, including previous contractual rates, customary rate increases and the current status of negotiations. Such estimates are adjusted as negotiations progress until new programming terms are finalized. In addition, the Company has received, or may receive, incentives from programming distributors for carriage of the distributors' programming. The Company generally recognizes these incentives as a reduction of programming costs and are recorded in "programming and other direct costs", generally over the term of the distribution agreement.
Advertising Expenses	Advertising Expenses Advertising costs are charged to expense when incurred and are reflected in "other operating expenses" in the accompanying consolidated statements of operations. Advertising costs amounted to $299,590, $274,639 and $213,474 for the years ended December 31, 2022, 2021 and 2020, respectively.
Share-based Compensation	Share-Based Compensation Share-based compensation expense which primarily relates to awards of stock options, restricted shares, performance stock units, and units in a carried unit plan is based on the fair value of share-based payment awards at the date of grant. The Company recognizes share-based compensation expense over the requisite service period or when it is
Income Taxes	Income TaxesThe Company's provision for income taxes is based on current period income, changes in deferred tax assets and liabilities and changes in estimates with regard to uncertain tax positions. Deferred tax assets are subject to an ongoing assessment of realizability.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company's cash investments are placed with money market funds and financial institutions that are investment grade as rated by S&P Global Ratings and Moody's Investors Service. The Company selects money market funds that predominantly invest in marketable, direct obligations issued or guaranteed by the United States government or its agencies, commercial paper, fully collateralized repurchase agreements, certificates of deposit, and time deposits. The Company considers the balance of its investment in funds that substantially hold securities that mature within three months or less from the date the fund purchases these securities to be cash equivalents. The carrying amount of cash and cash equivalents either approximates fair value due to the short-term maturity of these instruments or are at fair value.
Accounts Receivable	Accounts ReceivableAccounts receivable are recorded at net realizable value. 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.
Investments	Investment SecuritiesInvestment securities and investment securities pledged as collateral are carried at fair value with realized and unrealized holding gains and losses included in the consolidated statements of operations.
Long-Lived Assets and Amortizable Intangible Assets	Long-Lived Assets and Amortizable Intangible AssetsProperty, plant and equipment, including construction materials, are carried at cost, and include all direct costs and certain indirect costs associated with the construction of cable systems, and the costs of new equipment installations. Equipment under finance leases is recorded at the present value of the total minimum lease payments. Depreciation on equipment is calculated on the straight-line basis over the estimated useful lives of the assets or, with respect to equipment under finance lease obligations and leasehold improvements, amortized over the lease term or the assets' useful lives and reported in depreciation and amortization (including impairments) in the consolidated statements of operations.
Internal Use Software	The Company capitalizes certain internal and external costs incurred to acquire or develop internal-use software. Capitalized software costs are amortized over the estimated useful life of the software and reported in depreciation and amortization.
Amortizable Intangible Assets	Customer relationships, trade names and other intangibles established in connection with acquisitions that are finite-lived are amortized in a manner that reflects the pattern in which the projected net cash inflows to the Company are expected to occur, such as the sum of the years' digits method, or when such pattern does not exist, using the straight-line basis over their respective estimated useful lives.
Asset Impairment	The Company reviews its long-lived assets (property, plant and equipment, and intangible assets subject to amortization) for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the expected cash flows, undiscounted and without interest, is less than the carrying amount of the asset, an impairment loss is recognized as the amount by which the carrying amount of the asset exceeds its fair value.
Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets Goodwill and the value of franchises acquired in business combinations which have indefinite useful lives are not amortized. Rather, such assets are tested for impairment annually or upon the occurrence of a triggering event. The Company assesses the recoverability of its goodwill annually, or more frequently whenever events or substantive changes in circumstances indicate that the carrying amount of its reporting units may exceed their fair value. The Company first considers qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more-likely- than-not that the fair value of a reporting unit is less than its carrying amount. 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 testing is performed. 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. The Company assesses qualitative factors to determine whether it is necessary to perform the quantitative identifiable indefinite-lived intangible assets impairment test. This quantitative test is required only if the Company concludes that it is more likely than not that a unit of accounting’s fair value is less than its carrying amount. When the qualitative assessment is not used, or if the qualitative assessment is not conclusive, the impairment test for other intangible assets not subject to amortization requires a comparison of the fair value of the intangible asset with its carrying value. If the carrying value of the indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs, which are presented as a reduction of debt, are amortized to interest expense using the effective interest method over the terms of the related debt.
Derivative Financial Instruments	Derivative Financial InstrumentsThe Company accounts for derivative financial instruments as either assets or liabilities measured at fair value. The Company uses derivative instruments to manage its exposure to market risks from changes in certain equity prices and interest rates and does not hold or issue derivative instruments for speculative or trading purposes. These derivative instruments are not designated as hedges, and changes in the fair values of these derivatives are recognized in the consolidated statements of operations as gain (loss) on derivative contracts or gain (loss) on interest rate swap contracts.
Commitments and Contingencies	Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when the Company believes it is probable that a liability has been incurred and the amount of the contingency can be reasonably estimated.
Foreign Currency	Foreign CurrencyCertain of the Company's subsidiaries (including subsidiaries of i24 News S.à.r.l ("i24NEWS")) are located outside the United States. The functional currency for these subsidiaries is determined based on the primary economic environment in which the subsidiary operates. Revenues and expenses for these subsidiaries are translated into U.S. dollars using rates that approximate those in effect during the period while the assets and liabilities are translated into U.S. dollars using exchange rates in effect at the end of each period. The resulting gains and losses from these translations are recognized in cumulative translation adjustment included in accumulated other comprehensive income (loss) in stockholders’/member's equity (deficiency) on the consolidated balance sheets.
Common Stock and Membership Interests	Common Stock of Altice USA Each holder of Class A common stock has one vote per share while holders of Class B common stock have twenty-five votes per share. Class B shares can be converted to Class A common stock at anytime with a conversion ratio of one Class A common share for one Class B common share. The following table provides details of Altice USA's shares of common stock outstanding: Shares of Common Stock Outstanding Class A Class B Balance at December 31, 2019 446,749,307 186,245,832 Conversion of Class B common stock to Class A common stock 349,929 (349,929) Issuance of common shares 40,000 — Option exercises 822,732 — Repurchase and retirement of Class A common shares in connection with the Company's stock repurchase plan (see Note 1) (161,216,653) — Treasury shares reissued 3,828,357 — Balance at December 31, 2020 290,573,672 185,895,903 Conversion of Class B common stock to Class A common stock 1,562,561 (1,562,561) Option exercises 1,080,548 — Repurchase and retirement of Class A common shares in connection with the Company's stock repurchase plan (see Note 1) (23,593,728) — Treasury shares reissued 697,745 — Balance at December 31, 2021 270,320,798 184,333,342 Conversion of Class B common stock to Class A common stock 4,113 (4,113) Issuance of common shares in connection with the vesting of restricted stock units 1,506,186 — Treasury shares reissued 1,966 — Balance at December 31, 2022 271,833,063 184,329,229 CSC Holdings Membership Interests As of December 31, 2022 and 2021, CSC Holdings had 100 membership units issued and outstanding, which are all indirectly owned by Altice USA.
Dividends and Distributions	Dividends and Distributions Altice USA Altice USA may pay dividends on its capital stock only from net profits and surplus as determined under Delaware law. If dividends are paid on the Altice USA common stock, holders of the Altice USA Class A common stock and Altice USA Class B common stock are entitled to receive dividends, and other distributions in cash, stock or property, equally on a per share basis, except that stock dividends with respect to Altice USA Class A common stock may be paid only with shares of Altice USA Class A common stock and stock dividends with respect to Altice USA Class B common stock may be paid only with shares of Altice USA Class B common stock. The Company's indentures restrict the amount of dividends and distributions in respect of any equity interest that can be made. During 2022, 2021 and 2020, there were no dividends paid to shareholders by Altice USA. CSC Holdings CSC Holdings may make distributions on its membership interests only if sufficient funds exist as determined under Delaware law. See Note 16 for a discussion of equity distributions that CSC Holdings made to its parent.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that may potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents and trade account receivables. The Company monitors the financial institutions and money market funds where it invests its cash and cash equivalents with diversification among counterparties to mitigate exposure to any single financial institution. The Company's emphasis is primarily on safety of principal and liquidity and secondarily on maximizing the yield on its investments. Management believes that no significant concentration of credit risk exists with respect to its cash and cash equivalents because of its assessment of the creditworthiness and financial viability of the respective financial institutions. The Company did not have a single customer that represented 10% or more of its consolidated revenues for the years ended December 31, 2022, 2021 and 2020 or 10% or more of its consolidated net trade receivables at December 31, 2022, and 2021, respectively.
Use of Estimates in Preparation of Financial Statements	Use of Estimates in Preparation of Financial Statements The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. See Note 13 for a discussion of fair value estimates.
Reclassifications	Reclassifications Certain reclassifications have been made to the 2021 and 2020 amounts to conform to the 2022 presentation.

The Company adopted the guidance as of March 31, 2020. The adoption of this guidance did not have an impact on the Company's consolidated financial statements. ASU No. 2019-12, Simplifying the Accounting for Income Taxes ("ASU 2019-12") In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740). ASU 2019-12 simplifies the accounting for income taxes by eliminating certain exceptions for investments, intraperiod allocations and interim calculations. The new guidance also simplifies aspects of the accounting for franchise taxes, enacted changes in tax laws or rates, and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The amendments did not create new accounting requirements. The Company adopted the standard as of January 1, 2020. The adoption of this standard did not have a significant impact on 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 the standard as of January 1, 2020. The adoption of this standard did not have a significant impact on the Company's consolidated financial statements. ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350) ("ASU 2017-04") In January 2017, the FASB issued ASU 2017-04 which simplifies the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The amendment requires an entity to perform its annual, or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The Company adopted the standard as of January 1, 2020. The adoption of this standard did not have an impact on the Company's consolidated financial statements. 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 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. ASU 2016-13 became effective for the Company on January 1, 2020 and the adoption of this standard did not have a significant impact on the Company's consolidated financial statements. Accounting Standards Adopted in 2022 ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers , which will require companies to apply the definition of a performance obligation under ASC Topic 606, Revenue from Contracts with Customers, to recognize and measure contract assets and contract liabilities relating to contracts with customers that are acquired in a business combination. Under current GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded before the acquisition under ASC Topic 606. ASU No. 2021-08 is effective for the Company on January 1, 2023, however the Company elected to early adopt this ASU on January 1, 2022 and the Company will provide required disclosures for any future material transactions. ASU No. 2021-10, Government Assistance (Topic 832) In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832) , which requires business entities to disclose information about transactions with a government that are accounted for by applying a grant or contribution model by analogy (for example, IFRS guidance in IAS 20 or guidance on contributions for not-for-profit entities in ASC 958-605). For transactions in the scope of the new standard, business entities will need to provide information about the nature of the transaction, including significant terms and conditions, as well as the amounts and specific financial statement line items affected by the transaction. The Company adopted the new guidance on January 1, 2022 and it did not have a material impact on the Company's consolidated financial statements. The Company will provide the required disclosures for any future material transactions.
