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.a.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, through CSC Holdings, LLC (a wholly-owned subsidiary of Cablevision Systems Corporation) 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 has marketed its residential services primarily under two brands: Optimum, 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, Altice Business, 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. Altice USA is a holding company and has no business operations independent of its CSC Holdings subsidiary, whose operating results and financial position are consolidated into Altice USA. 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 has additional cash and deferred taxes on its consolidated balance sheet. 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 or 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.

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and with the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, these financial statements do not include all the information and notes required for complete annual financial statements. The interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021. The financial statements presented in this report are unaudited; however, in the opinion of management, such financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the results for the periods presented. The results of operations for the interim periods are not necessarily indicative of the results that might be expected for future interim periods or for the full year ending December 31, 2022. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. See Note 10 for a discussion of fair value estimates.

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 such 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 for the three and nine months ended September 30, 2022 and 2021: Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 (in thousands) Basic weighted average shares outstanding 453,239 454,049 453,233 460,023 Effect of dilution: Stock options — 3,114 — 5,311 Restricted stock units 151 — 51 15 Diluted weighted average shares outstanding 453,390 457,163 453,284 465,349 Weighted average shares excluded from diluted weighted average shares outstanding: Anti-dilutive shares 57,538 26,453 57,950 9,381 Performance stock units and restricted stock whose performance metrics have not been achieved. 7,298 8,618 7,481 8,704 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.

(d) There were no borrowings outstanding under the Lightpath Revolving Credit Facility which provides for commitments in an aggregate principal amount of $100,000. Borrowings 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. (e) Includes $112,546 as of September 30, 2022 and $89,898 as of December 30, 2021 related to supply chain financing agreements that are required to be repaid within one year from the date of the respective agreement. (f) This indebtedness is collateralized by shares of Comcast common stock. Our intent is to settle such indebtedness with proceeds from new monetization contracts. To the extent we do not enter into new monetization contracts, we could settle the existing collateralized indebtedness by (i) delivering shares of Comcast common stock or (ii) delivering cash. Because this collateralized debt matures in May 2023, it has been classified as current in the accompanying balance sheet as of September 30, 2022, and because there is no assurance that a financing under new monetization contracts can be completed when this debt matures, the related investments held as collateral have also been classified as current. 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 and excludes Cablevision Lightpath LLC ("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. Both CSC Holdings and Lightpath's credit facilities agreements contain 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 credit facilities will be entitled to take various actions, including the acceleration of amounts due under the credit facilities and all actions permitted to be taken by a secured creditor. As of September 30, 2022, CSC Holdings and Cablevision 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. On July 13, 2022, CSC Holdings entered into an amendment (the "Twelfth Amendment") to its senior secured credit facility (the "Credit Agreement"). The Twelfth Amendment provides for, among other things, an extended maturity until the date that is the earlier of (i) July 13, 2027 and (ii) April 17, 2025 if, as of such date, any March 2017 Term Loans, as defined in the Credit Agreement are still outstanding, unless the March 2017 Term Loan Maturity Date (as defined in the Credit Agreement) 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. Summary of Debt Maturities The future maturities of debt payable by the Company under its various debt obligations outstanding as of September 30, 2022, including notes payable and collateralized indebtedness (see Note 9), but excluding finance lease obligations, are as follows: 2022 $ 52,965 2023 1,920,994 2024 828,889 2025 2,823,750 2026 1,224,938 Thereafter 19,311,500

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 and the fair value of the remaining interest payments on the debt less the sum of the fair values of the underlying stock and equity collars calculated at the termination date. As of September 30, 2022, the Company had an early termination shortfall of $449 relating to such 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 September 30, 2022. In January 2021, the Company settled collateralized indebtedness and an equity derivative contract aggregating $185,105 upon maturity related to 5,337,750 shares of Comcast common stock held by us, with proceeds of $185,105 received in January 2021 pursuant to the synthetic monetization closeout transaction in November 2019. In connection with this transaction the Company recorded (i) a decrease in notes payable of $59,451 and (ii) an increase in collateralized debt of $59,451. 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. All such contracts are carried at their fair market values on our consolidated balance sheets, with changes in fair value reflected in the consolidated statements of operations. As of September 30, 2022, the Company did not hold and has not issued derivative instruments for trading or speculative purposes. The following represents the location of the assets and liabilities associated with the Company's derivative instruments within the consolidated balance sheets: Derivatives Not Designated as Hedging Instruments Balance Sheet Location Fair Value at September 30, 2022 December 31, 2021 Asset Derivatives: Interest rate swap contracts Prepaid expenses and other current assets $ — $ 2,993 Prepaid forward contracts Derivative contracts 481,914 — Interest rate swap contracts Other asset, long-term 188,970 — 670,884 2,993 Liability Derivatives: Interest rate swap contracts Other current liabilities — (3,441) Prepaid forward contracts Liabilities under derivative contracts, long-term — (161,942) Interest rate swap contracts Liabilities under derivative contracts, long-term — (114,991) $ — $ (280,374) The following table presents certain consolidated statement of operations data related to our interest rate swaps, our derivative contracts and the underlying common stock relating to the derivative contracts: Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Gain (loss) on derivative contracts related to change in the value of equity derivative contracts related to Comcast common stock $ 323,668 $ 43,385 $ 643,856 $ (109,020) Change in the fair value of Comcast common stock included in gain (loss) on investments (425,686) (46,821) (902,060) 151,632 Gain on interest rate swap contracts, net 105,945 5,521 268,960 59,600 The following is a summary of interest rate swap contracts outstanding at September 30, 2022: Maturity Date Notional Amount Company Pays Company Receives CSC Holdings: January 2025 $ 500,000 Fixed rate of 1.53% Three-month LIBOR January 2025 500,000 Fixed rate of 1.625% Three-month LIBOR January 2025 500,000 Fixed rate of 1.458% Three-month LIBOR December 2026 750,000 Fixed rate of 2.9155% Three-month LIBOR December 2026 750,000 Fixed rate of 2.9025% Three-month LIBOR Lightpath: December 2026 (a) 300,000 Fixed rate of 2.161% One-month LIBOR (a) Interest rate swap contract was effective April 2022.

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT	9 Months Ended
	Sep. 30, 2022
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENTThe 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 September 30, 2022 December 31, 2021 Assets: Money market funds Level I $ 128,616 $ 100,015 Investment securities pledged as collateral Level I 1,259,877 2,161,937 Prepaid forward contracts Level II 481,914 — Interest rate swap contracts Level II 188,970 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 6,698 — 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 September 30, 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: September 30, 2022 December 31, 2021 Fair Value Carrying Estimated Carrying Estimated Credit facility debt Level II $ 8,844,687 $ 8,887,375 $ 8,495,611 $ 8,546,438 Collateralized indebtedness Level II 1,736,294 1,717,146 1,706,997 1,741,710 Senior guaranteed notes and senior secured notes Level II 8,080,433 6,568,450 8,077,372 8,180,813 Senior notes Level II 7,321,810 5,391,150 7,950,241 7,883,071 Notes payable and supply chain financing Level II 116,644 116,231 97,804 97,588 $ 26,099,868 $ 22,680,352 $ 26,328,025 $ 26,449,620 (a) Amounts are net of unamortized deferred financing costs and discounts/premiums and with respect to certain notes, a fair value adjustment resulting from the Cequel and Cablevision acquisitions.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES In general, the Company is required to use an estimated annual effective tax rate ("AETR") to measure the income tax expense or benefit recognized on a year to date basis in an interim period. In addition, certain items included in income tax expense as well as the tax impact of certain items included in pretax income must be treated as discrete items. The income tax expense or benefit associated with these discrete items is fully recognized in the interim period in which the items occur. For the three and nine months ended September 30, 2022, the Company recorded a tax expense of $35,827 and $152,563 on pre-tax income of $133,448 and $565,865, respectively, resulting in an effective tax rate that was higher than the U.S. statutory tax rate. The higher tax rate was primarily due to the impact of certain non-deductible expenses and state tax expense. For the three and nine months ended September 30, 2021, the Company recorded a tax expense of $105,226 and $279,053 on pre-tax income of $375,975 and $1,029,275, respectively, resulting in an effective tax rate that was higher than the U.S. statutory tax rate. The higher tax rate was due to the impact of certain non-deductible expenses and state tax expense.

COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Matters On June 23, 2020, a purported stockholder of the Company filed a complaint in the Court of Chancery of the State of Delaware, derivatively on behalf of the Company, against Patrick Drahi, Next Alt S.à.r.l., and those directors of the Company who are members of the Compensation Committee (collectively, the “Director Defendants”). The Company is also named as a nominal defendant in the complaint. The complaint alleges that the Director Defendants breached their fiduciary duties to the Company’s stockholders, and wasted corporate assets, by approving certain equity grants for Patrick Drahi. The complaint seeks rescission of the equity awards, monetary damages, and costs and disbursements for the plaintiff. On October 15, 2020, the Director Defendants answered the complaint and the Company filed a general denial of liability. Following negotiations with plaintiff, the parties executed a stipulation and agreement of compromise, settlement, and release on April 27, 2022 to settle the litigation. On November 1, 2022, the settlement was approved by the court. 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. Trial is scheduled to commence on December 12, 2022, at which we expect Sprint to seek as much as $250 million in damages. The Company intends to vigorously defend the lawsuit. The Company has received from UMG Recordings, Inc., Capitol Records, LLC, and BMG Rights Management (US) LLC letters alleging that the Company has not adequately addressed copyright infringement on its networks and is subject to liability and damages for secondary copyright infringement. The Company intends to vigorously defend these claims. Although the outcome of the above matters cannot be predicted and the impact of a final resolution of these matters on the Company’s results of operations or financial position is not known or reasonably estimable at this time, management does not believe that the ultimate resolution of the matters, individually or together, will have a material adverse effect on the operations or financial position of the Company or the ability of the Company to meet its financial obligations as they become due, but they could be material to the Company’s consolidated results of operations or cash flows for any one period. In addition to the matters discussed above, the Company also receives notices from third parties, and in some cases is named as a defendant in lawsuits, claiming infringement of various patents or copyrights relating to various aspects of the Company's businesses. In certain of these cases other industry participants are also defendants, and in certain of these cases the Company expects that some or all potential liability would be the responsibility of the Company's vendors pursuant to applicable contractual indemnification provisions. In the event that the Company is found to infringe on any patent or other intellectual property rights, the Company may be subject to substantial damages and/or an injunction that could require the Company or its vendors to modify certain products and services the Company offers to its subscribers, as well as enter into royalty or license agreements with respect to the patents at issue. The Company is also party to various other lawsuits, disputes and investigations arising in the ordinary course of its business, some of which may involve claims for substantial damages, fines or penalties. Although the outcome of these matters cannot be predicted and the impact of the final resolution of these matters on the Company's results of operations in a particular subsequent reporting period is not known, management does not believe that the resolution of these matters, individually, will have a material adverse effect on the operations or financial position of the Company or the ability of the Company to meet its financial obligations as they become due.

Recently Adopted Accounting Pronouncements and Recently Issued But Not Yet Adopted Accounting Pronouncements	ACCOUNTING STANDARDS 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 Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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. The guidance will be applied to any future business combinations. 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 the Company will provide 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.

(b) At September 30, 2022, $131,894 of the revolving credit facility was restricted for certain letters of credit issued on behalf of the Company and $1,043,106 of the facility was undrawn and available, subject to covenant limitations. (c) The revolving credit facility provides for commitments in an aggregate principal amount of $2,475,000. (d) There were no borrowings outstanding under the Lightpath Revolving Credit Facility which provides for commitments in an aggregate principal amount of $100,000. Borrowings 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. (e) Includes $112,546 as of September 30, 2022 and $89,898 as of December 30, 2021 related to supply chain financing agreements that are required to be repaid within one year from the date of the respective agreement. (f) This indebtedness is collateralized by shares of Comcast common stock. Our intent is to settle such indebtedness with proceeds from new monetization contracts. To the extent we do not enter into new monetization contracts, we could settle the existing collateralized indebtedness by (i) delivering shares of Comcast common stock or (ii) delivering cash. Because this collateralized debt matures in May 2023, it has been classified as current in the accompanying balance sheet as of September 30, 2022, and because there is no assurance that a financing under new monetization contracts can be completed when this debt matures, the related investments held as collateral have also been classified as current.
