PART I.     FINANCIAL INFORMATION

This Quarterly Report includes statements that express our opinions, expectations, beliefs, plans, objectives, assumptions or projections regarding future events or future results and therefore are, or may be deemed to be, “forward‑looking statements.” These “forward‑looking statements” appear throughout this Quarterly Report and relate to matters such as anticipated future growth in revenues, operating income, cash provided by operating activities and other financial measures. Words such as “expects,” “anticipates,” “believes,” “estimates,” “may,” “will,” “should,” “could,” “seeks,” “potential,” “continue,” “intends,” “plans” and similar words and terms used in the discussion of future operating results, future financial performance and future events identify forward‑looking statements. All of these forward‑looking statements are based on management’s current expectations and beliefs about future events. As with any projection or forecast, they are susceptible to uncertainty and changes in circumstances.

We operate in a highly competitive, consumer and technology driven and rapidly changing business that is affected by government regulation and economic, strategic, technological, political and social conditions. Various factors could adversely affect our operations, business or financial results in the future and cause our actual results to differ materially from those contained in the forward‑looking statements. In addition, important factors that could cause our actual results to differ materially from those in our forward‑looking statements include:

• competition for broadband, pay television and telephony customers from existing competitors (such as broadband communications companies, direct broadcast satellite ("DBS") providers and Internet‑based providers) and new competitors entering our footprint;

• changes in consumer preferences, laws and regulations or technology that may cause us to change our operational strategies;

• increased difficulty negotiating programming agreements on favorable terms, if at all, resulting in increased costs to us and/or the loss of popular programming;

• increasing programming costs and delivery expenses related to our products and services;

• our ability to achieve anticipated customer and revenue growth, to successfully introduce new products and services and to implement our growth strategy;

• our ability to complete our capital investment plans on time and on budget, including our plan to build a fiber-to-the-home ("FTTH") network, and deploy Altice One, our new home communications hub;

• our ability to develop and deploy mobile voice and data services pursuant to the agreement we entered into with Sprint in the fourth quarter of 2017;

• the effects of economic conditions or other factors which may negatively affect our customers’ demand for our products and services;

• the effects of industry conditions;

• demand for advertising on our cable systems;

• our substantial indebtedness and debt service obligations;

• adverse changes in the credit market;

• changes as a result of any tax reforms that may affect our business;

• financial community and rating agency perceptions of our business, operations, financial condition and the industries in which we operate;

• the restrictions contained in our financing agreements;

• our ability to generate sufficient cash flow to meet our debt service obligations;

• fluctuations in interest rates which may cause our interest expense to vary from quarter to quarter;

• technical failures, equipment defects, physical or electronic break‑ins to our services, computer viruses and similar problems;

1

• the disruption or failure of our network, information systems or technologies as a result of computer hacking, computer viruses, “cyber‑attacks,” misappropriation of data, outages, natural disasters and other material events;

• our ability to obtain necessary hardware, software, communications equipment and services and other items from our vendors at reasonable costs;

• our ability to effectively integrate acquisitions and to maximize expected operating efficiencies from our acquisitions or as a result of the transactions, if any;

• significant unanticipated increases in the use of bandwidth‑intensive Internet‑based services;

• the outcome of litigation, government investigations and other proceedings;

• our ability to successfully operate our business following the completion of our separation from Altice N.V.;and

• other risks and uncertainties inherent in our cable and other broadband communications businesses and our other businesses, including those listed under the caption “Risk Factors” in the Company's Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on March 6, 2018 (the "Annual Report").

These factors are not necessarily all of the important factors that could cause our actual results to differ materially from those expressed in any of our forward‑looking statements. Other unknown or unpredictable factors could cause our actual results to differ materially from those expressed in any of our forward‑looking statements.

Given these uncertainties, you are cautioned not to place undue reliance on such forward‑looking statements. The forward‑looking statements are made only as of the date of this Quarterly Report. Except to the extent required by law, we do not undertake, and specifically decline any obligation, to update any forward‑looking statements or to publicly announce the results of any revisions to any of such statements to reflect future events or developments. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.

You should read this Quarterly Report with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect. We qualify all forward‑looking statements by these cautionary statements.

Certain numerical figures included in this quarterly report have been subject to rounding adjustments. Accordingly, such numerical figures shown as totals in various tables may not be arithmetic aggregations of the figures that precede them.

NOTE 1.    DESCRIPTION OF BUSINESS AND RELATED MATTERS

The Company and Related Matters

Altice USA, Inc. ("Altice USA" or the "Company") was incorporated in Delaware on September 14, 2015. Prior to the Altice N.V. distribution discussed below, Altice USA was majority‑owned by Altice N.V., a public company with limited liability (naamloze vennootshcap) under Dutch law. Since the completion of the Altice N.V. distribution discussed below, the Company is no longer majority-owned by Altice N.V.

The Company provides broadband communications and video services in the United States. It delivers broadband, pay television, telephony services, proprietary content and advertising services to residential and business customers.

Altice N.V., through a subsidiary, acquired Cequel Corporation ("Cequel" or "Suddenlink") 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" or "Optimum") on June 21, 2016 (the "Cablevision Acquisition").

The Company classifies its operations into two reportable segments: Cablevision, which operates in the New York metropolitan area, and Cequel, which principally operates in markets in the south‑central United States.

The accompanying condensed combined consolidated financial statements ("condensed consolidated financial statements") include the accounts of the Company and all subsidiaries in which the Company has a controlling interest and gives effect to the ATS Acquisition and the i24 Acquisition discussed below on a combined basis. All significant inter-company accounts and transactions have been eliminated in consolidation.

The accompanying condensed consolidated operating results for the three and six months ended June 30, 2017 reflect the retrospective adoption of Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers and ASU No. 2017‑07 Compensation-Retirement Benefits (Topic 715). See Note 3 for further details of the impact on the Company's historical financial statements.

In June 2017, the Company completed its initial public offering ("IPO") of 71,724,139 shares of its Class A common stock. The Company’s Class A common stock began trading on June 22, 2017, on the New York Stock Exchange under the symbol "ATUS".

Acquisition of Altice Technical Services US Corp

ATS was formed in 2017 to provide network construction and maintenance services and commercial and residential installations, disconnections, and maintenance. During the second quarter of 2017, a substantial portion of the Company's technical workforce at the Cablevision segment either accepted employment with ATS or became employees of ATS and ATS commenced operations and began to perform services for the Company. A substantial portion of the Cequel segment technical workforce became employees of ATS in December 2017.

In January 2018, the Company acquired 70% of the equity interests in Altice Technical Services US Corp. ("ATS") for $1.00 (the "ATS Acquisition") and the Company became the owner of 100% of the equity interests in ATS in March 2018. ATS was previously owned by Altice N.V. and a member of ATS's management through a holding company. As the acquisition was a combination of businesses under common control, the Company combined the results of operations and related assets and liabilities of ATS for all periods since its formation. See Note 3 for the impact of the ATS Acquisition on the Company's condensed consolidated balance sheet as of December 31, 2017 and on the Company's statement of operations for the three and six months ended June 30, 2017.

Acquisition of i24NEWS

In April 2018, Altice N.V. transferred its ownership of i24 US and i24 Europe ("i24NEWS"), Altice N.V.'s 24/7 international news and current affairs channels to the Company for minimal consideration (the "i24 Acquisition"). As the acquisition was a combination of businesses under common control, the Company combined the results of operations and related assets and liabilities of i24NEWS as of April 1, 2018. Operating results for periods prior to April 1, 2018 and the balance sheet as of December 31, 2017 have not been revised to reflect the i24 Acquisition as the impact was deemed immaterial.

Altice N.V. Distribution

On June 8, 2018, Altice N.V. distributed substantially all of its equity interest in the Company through a distribution in kind to holders of Altice N.V.'s common shares A and common shares B (the “Distribution”). The Distribution took place by way of a special distribution in kind by Altice N.V. of its 67.2% interest in the Company to Altice N.V. shareholders. Each shareholder of Altice N.V. on May 23, 2018, the Distribution record date, received 0.4163 shares of the Company's common stock for every share held by such shareholder in Altice N.V. Between May 24, 2018 and June 4, 2018, each Altice N.V. shareholder was given the opportunity to elect the percentage of shares of the Company's Class A common stock and shares of the Company's Class B common stock such shareholder would receive in the Distribution, whereby the number of shares of the Company's Class B common stock to be distributed was subject to a cap of 50% of the total shares of the Company's common stock being distributed (the “Class B Cap”). Because the Class B Cap had been exceeded, the shares of the Company's Class B common stock delivered to Altice N.V.’s shareholders of record who elected to receive them were subject to proration, and such shareholders received shares of the Company's Class A common stock.

Immediately following the Distribution, there were 489,384,523 shares of Altice USA Class A common stock and 247,684,443 shares of Altice USA Class B common stock outstanding.

Prior to Altice N.V.'s announcement of the Distribution, the Board of Directors of Altice USA, acting through its independent directors, approved the payment of a $2.035 dividend to all shareholders of record on May 22, 2018. The payment of the dividend, aggregating $1,499,935, was made on June 6, 2018, and wasfunded with cash at CSC Holdings LLC, a wholly-owned subsidiary of Cablevision, from financings completed in January 2018 and cash generated from operations at Cequel. In connection with the payment of the dividend, the Company recorded a decrease in retained earnings of $536,224, representing the cumulative earnings through the payment date, and a decrease in paid in capital of $963,711.

In addition, the Board of Directors of Altice USA also authorized a share repurchase program of $2.0 billion, effective June 8, 2018.

In connection with the Distribution, the Management Advisory and Consulting Services Agreement with Altice N.V. which provided certain consulting, advisory and other services was terminated. Compensation under the terms of the agreement was an annual fee of $30,000 paid by the Company.

NOTE 2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accompanying unaudited condensed 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 condensed 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, 2017 and the Company's financial statements and notes thereto included on Form 8-K filed on May 21, 2018.

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, 2018.

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.

Recently Adopted Accounting Pronouncements

In February 2018, the FASB issued ASU No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The primary provision of ASU No. 2018-02 allows for the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. ASU No. 2018-02 also requires certain disclosures about stranded tax effects. ASU No. 2018‑02 is effective for the Company on January 1, 2019, with early adoption permitted and will be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company elected to adopt ASU No. 2018-02 during the first quarter of 2018. The adoption resulted in the reclassification of stranded tax amounts of $2,163 associated with net unrecognized losses from the Company's pension plans from accumulated other comprehensive loss to retained earnings.

In May 2017, the FASB issued ASU No. 2017-09, Compensation- Stock Compensation (Topic 718). ASU No. 2017‑09 provides clarity and guidance on which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU No. 2017‑09 was adopted by the Company on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits (Topic 715). ASU No. 2017‑07 requires that an employer disaggregate the service cost component from the other components of net benefit cost. It also provides guidance on how to present the service cost component and the other components of net benefit cost in the income statement and what component of net benefit cost is eligible for capitalization. ASU No. 2017‑07 was adopted by the Company on January 1, 2018 and was applied retrospectively. As a result of the adoption, the Company reclassified the non-service cost components of the Company's pension expense for the three and six months ended March 31, 2017 from other operating expenses to other income (expense), net. The Company elected to apply the practical expedient which allowed it to reclassify amounts disclosed previously in the benefits plan note as the basis for applying retrospective presentation for comparative periods, as the Company determined it was impracticable to disaggregate the cost components for amounts capitalized and amortized in those periods. See Note 3 for information on the impact of the adoption of ASU No. 2017-07.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business, which amends Topic 805 to interpret the definition of a business by adding guidance to assist in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company adopted the new guidance on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities.  ASU No. 2016-01 modifies how entities measure certain equity investments and also modifies the recognition of changes in the fair value of financial liabilities measured under the fair value option. Entities will be required to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income. For financial liabilities measured using the fair value option, entities will be required to record changes in fair value caused by a change in instrument-specific credit risk (own credit risk) separately in other comprehensive income. ASU No. 2016-01 was adopted by the Company on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ("ASC 606"), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASC 606 replaced most existing revenue recognition guidance in GAAP and allowed the use of either the retrospective or cumulative effect transition method.

In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, in order to clarify the Codification and to correct any unintended application of the guidance. The amendments in this update affected the guidance in ASC 606. ASC 606 was adopted by the Company on January 1, 2018 on a full retrospective basis, which required the Company to reflect the impact of the updated guidance for all periods presented. The adoption of ASC 606 did not have a material impact on the Company’s financial position or results of operations. See Note 3 for information on the impact of the adoption of ASC 606.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. ASU No. 2016-15 also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The Company adopted the new guidance on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

Recently Issued But Not Yet Adopted Accounting Pronouncements

In January 2017, the FASB issued ASU No. 2017‑04, Intangibles-Goodwill and Other (Topic 350). ASU No. 2017‑04 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. ASU No. 2017‑04 becomes effective for the Company on January 1, 2020 with early adoption permitted and will be applied prospectively.

In February 2016, the FASB issued ASU No. 2016-02, Leases, which increases transparency and comparability by recognizing a lessee’s rights and obligations resulting from leases by recording them on the balance sheet as lease assets and lease liabilities. The new guidance becomes effective for the Company on January 1, 2019. Although, the Company has not yet completed the evaluation of the effect that ASU No. 2016-02 will have on its consolidated financial statements, upon adoption, the Company expects to recognize a right of use asset and liability related to substantially all operating lease arrangements on the Company's consolidated balance sheet.

Reclassifications

Certain reclassifications have been made to the 2017 financial statements to conform to the 2018 presentation.

NOTE 3.    CHANGE IN ACCOUNTING POLICIES AND ATS ACQUISITION

Adoption of ASC 606 - Revenue from Contracts with Customers

On January 1, 2018, the Company adopted the guidance pursuant to ASC 606. The Company elected to apply the guidance on a full retrospective basis, which required the Company to reflect the impact of the updated guidance for all periods presented. The adoption of the guidance resulted in the deferral of certain installation revenue, the deferral of certain commission expenses, and a reduction of revenue due to the reclassification of certain third party giveaways and incentives from operating expense. Additionally, the Company made changes in the composition of revenue resulting from the allocation of value related to bundled services sold to residential customers at a discount.

Installation Services Revenue

Pursuant to ASC 606, the Company's installation services revenue is deferred and recognized over the benefit period. For residential customers, the benefit period is less than one year. For business and wholesale customers, the benefit period is the contract term. Prior to the adoption of ASC 606, the Company recognized installation services revenue for residential and small and medium-sized business ("SMB") customers when installations were completed. As a result of the deferral of installation services revenue for residential and SMB customers, the Company recognized contract liabilities of $6,978 and recorded a cumulative effect adjustment of $5,093 (net of tax of $1,885) to retained earnings. The accounting for installation services revenue related to business and wholesale customers has not changed.

Commission Expenses

Pursuant to ASC 606, the Company defers commission expenses related to obtaining a contract with a customer when the expected period of benefit is greater than one year and amortizes these costs over the average contract term. For commission expenses related to customer contracts with a term of one year or less, the Company is utilizing the practical expedient and is recognizing the costs when incurred.  Prior to the adoption of ASC 606, the Company recognized commission expenses related to the sale of its services when incurred. As a result of the change in the timing of recognition of these commission expenses, the Company recognized contract assets of $24,329 and recorded a cumulative effect adjustment of $17,759 (net of tax of $6,570) to retained earnings.

(Unaudited)

Third Party Product Giveaways and Incentives

When the Company acts as the agent in providing certain product giveaways or incentives, revenue is recorded net of the costs of the giveaways and incentives. For the three and six months ended June 30, 2017, costs of $5,979 and $9,396, respectively for the giveaways and incentives recorded in other operating expense have been reclassified to revenue.

Bundled Services

The Company provides bundled services at a discounted rate to its customers. Under ASC 606, revenue should be allocated to separate performance obligations within a bundled offering based on the relative stand-alone selling price of each service within the bundle.In connection with the adoption of ASC 606, the Company revised the amounts allocated to each performance obligation within its bundled offerings which reduced previously reported revenue for telephony services and increased previously reported revenue allocated to pay television and broadband services.

Adoption of ASU No. 2017-07 - Compensation-Retirement Benefits (Topic 715)

On January 1, 2018, the Company adopted the guidance pursuant to ASU No. 2017‑07. ASU No. 2017‑07 requires that an employer disaggregate the service cost component from the other components of net benefit cost. In connection with the adoption of ASU No. 2017‑07, the Company retroactively reclassified certain pension costs from other operating expenses to other income (expense), net. The adoption of ASU No. 2017-07 had no impact on the Company's condensed consolidated balance sheet.

Acquisition of ATS

As discussed in Note 1, the Company completed the ATS Acquisition in the first quarter of 2018. ATS was previously owned by Altice N.V. and a member of ATS's management through a holding company. As the acquisition is a combination of businesses under common control, the Company combined the results of operations and related assets and liabilities of ATS for all periods since the formation of ATS, including goodwill of $23,101, representing the amount previously transferred to ATS.

The following table summarizes the impact of adopting ASC 606 and the impact of the ATS Acquisition on the Company's condensed consolidated balance sheet:

NOTE 4.    NET LOSS PER SHARE ATTRIBUTABLE TO STOCKHOLDERS

Basic net loss per common share attributable to Altice USA stockholders is computed by dividing net loss attributable to Altice USA stockholders by the weighted average number of common shares outstanding during the period.  Diluted net loss per common share attributable to Altice USA stockholders excludes the effects of common stock equivalents as they are anti-dilutive.

The weighted average number of shares used to compute basic and diluted net loss per share for the three and six months ended June 30, 2017 reflect the retroactive impact of certain organizational transactions that occurred prior to the Company's IPO.

NOTE 5.    REVENUE AND CONTRACT ASSETS

Revenue Recognition

Residential Services

The Company derives revenue through monthly charges to residential customers of its pay television, broadband, 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 pay TV" revenues. The Company recognizes pay television, broadband, and telephony revenues as the services are provided to a customer on a monthly basis. 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 three and six months ended June 30, 2018 the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $63,362 and $127,192, respectively. For the three and six months ended June 30, 2017 the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $64,804 and $129,790, respectively.

Business and Wholesale Services

The Company derives revenue from the sale of products and services to both large enterprise and SMB customers, including broadband, telephony, networking, and pay television 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 Wi-Fi, 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 and enable 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 also on a monthly basis. Contracts with large enterprise customers typically range from three to five years. Installation revenue related to our large enterprise customers is deferred and recognized over the average contract term. Installation revenue related to SMB customers is deferred and recognized over the benefit period, which is less than a year. The estimated benefit period for SMB customers takes into account both quantitative and qualitative factors including the significance of average installation fees to total recurring revenue per customer.

Advertising

As part of the agreements under which the Company acquires pay television 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. Advertising revenues are recognized when commercials are aired. 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. 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.

The Company's advanced advertising businesses provide data-driven, audience-based advertising solutions using advanced analytics tools that provide granular measurement of consumer groups, accurate hyper-local ratings and other insights into target audience behavior not available through traditional sample-based measurement services. Revenue earned from the Company's advanced advertising businesses are recognized when services are provided.

Other

Revenues derived from other sources are recognized when services are provided or events occur.

Contract Assets

Incremental costs incurred in obtaining a contract with a customer are deferred and recorded as a contract asset if the period of benefit is expected to be greater than one year. Sales commissions for enterprise and certain SMB customers are deferred and amortized over the average contract term. For sales commission expenses related to residential and SMB customers with a term of one year or less, the Company is utilizing the practical expedient and is recognizing the costs when incurred.  Cost of fulfilling a contract with a customer are deferred and recorded as a contract 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.

The following table provides information about contracts assets and contract liabilities related to contracts with customers:

	June 30, 2018		December 31, 2017, as adjusted
Contract assets (a)	$	24,358	$	24,329
Deferred revenue (b)	138,165		117,679

(a) Contract assets include primarily sales commissions for enterprise customers that are deferred and amortized over the average contract term.

(b) Deferred revenue represents payments received from customers for services that have yet to be provided and installation revenue which is deferred and recognized over the benefit period. The majority of the Company's deferred revenue represents payments for services for up to one month in advance from residential and SMB customers which is realized within the following month as services are performed.

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 to five years, and services may only be terminated in accordance with the contractual terms.

NOTE 10.    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 condensed 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 condensed 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 condensed consolidated statements of operations.

(Unaudited)

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 were 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 June 30, 2018, 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 June 30, 2018.

Interest Rate Swap Contracts

In May 2018, the Company entered into two interest rate swap contracts whereby one contract converts the interest rate on $2,970,000 of the CSC Holdings Term Loan Facility from a one-month LIBO rate to a three-month LIBO rate minus 0.226% and the second contract converts the interest rate on $1,496,250 of the CSC Holdings Incremental Term Loan from a one-month LIBO rate to a three-month LIBO rate minus 0.226%. The objective of these swaps is to potentially pay a lower interest rate than what the Company can elect under the terms of the CSC Holdings credit facilities agreement.

In April 2018, the Company entered into an interest rate swap contract which converts the interest rate on $1,255,513 of the Cequel Term Loan B from a one-month LIBO rate to a three-month LIBO rate minus 0.225%. The objective of this swap is to potentially pay a lower interest rate than what the Company can elect under the terms of the Cequel credit facilities agreement.

In June 2016, the Company entered into two fixed to floating interest rate swap contracts. One fixed to floating interest rate swap is converting $750,000 from a fixed rate of 1.6655% to a six-month LIBO rate and a second tranche of $750,000 from a fixed rate of 1.68% to a six-month LIBO rate. The objective of these swaps is to adjust the proportion of total debt that is subject to fixed and variable interest rates.

These swap contracts were not designated as hedges for accounting purposes. Accordingly, the changes in the fair value of these interest rate swap contracts are recorded through the statements of operations.

The Company does not hold or issue 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 condensed consolidated balance sheets:

		Asset Derivatives				Liability Derivatives
Derivatives Not Designated as Hedging Instruments	Balance Sheet Location	Fair Value at June 30, 2018		Fair Value at December 31, 2017		Fair Value at June 30, 2018			Fair Value at December 31, 2017
Interest rate swap contracts	Derivative contracts, current	$	369	$	—	$	—		$	—
Prepaid forward contracts	Derivative contracts, current	9,623		52,545		(9,623		)	(52,545		)

		$	110,999	$	52,545	$	(133,093	)	$	(239,951	)

Gains from the Company's derivative contracts related to the Comcast common stock for the three and six months ended June 30, 2018 of $42,159 and $210,511, respectively, are reflected in gain (loss) on derivative contracts, net in the Company's condensed consolidated statement of operations.

For the three and six months ended June 30, 2018 , the Company recorded a loss on investments of $58,420 and $310,996, respectively, primarily representing the net decrease in the fair values of the investment securities pledged as collateral. 

24

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

(Dollars in thousands, except share and per share amounts)

(Unaudited)

For the three and six months ended June 30, 2018, the Company recorded a loss on interest rate swap contracts of $12,929 and $44,851, respectively.

Settlements of Collateralized Indebtedness

The following table summarizes the settlement of the Company's collateralized indebtedness relating to Comcast shares that were settled by delivering cash equal to the collateralized loan value, net of the value of the related equity derivative contracts during the six months ended June 30, 2018: 

Number of shares (a)	10,802,118
Collateralized indebtedness settled	$	(337,148	)
Derivatives contracts settled	24
	(337,124		)
Proceeds from new monetization contracts	337,124
Net cash proceeds	$	—

The cash to settle the collateralized indebtedness was obtained from the proceeds of new monetization contracts covering an equivalent number of Comcast shares.  The terms of the new contracts allow the Company to retain upside participation in Comcast shares up to each respective contract's upside appreciation limit with downside exposure limited to the respective hedge price. 

NOTE 11.    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 for each of these hierarchy levels, the Company's financial assets and financial liabilities that are measured at fair value on a recurring basis:

	Fair Value Hierarchy	June 30, 2018		December 31, 2017
Assets:
Money market funds	Level I	$	218,940	$	5,949
Investment securities pledged as collateral	Level I	1,409,361		1,720,357
Prepaid forward contracts	Level II	110,630		52,545
Interest rate swap contracts	Level II	369		—
Liabilities:
Prepaid forward contracts	Level II	9,623		162,049
Interest rate swap contracts	Level II	123,470		77,902
Contingent consideration related to 2017 acquisitions	Level III	2,233		32,233

The Company's cash equivalents, investment securities 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 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

25

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

(Dollars in thousands, except share and per share amounts)

(Unaudited)

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 June 30, 2018 related to the acquisition in the fourth quarter of 2017 amounted to approximately $2,233. The estimated amount recorded as of June 30, 2018 is approximately 51% of the contractual amount. The fair value of the consideration was estimated based on a probability assessment of attaining the targets as of June 30, 2018.

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 and Debentures, Senior Secured Notes, Senior Guaranteed Notes, and Notes Payable

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 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 condensed consolidated balance sheets, are summarized as follows:

		June 30, 2018				December 31, 2017
	Fair Value Hierarchy	Carrying Amount (a)		Estimated Fair Value		Carrying Amount (a)		Estimated Fair Value
CSC Holdings debt instruments:
Credit facility debt	Level II	$	4,435,479	$	4,470,000	$	3,393,306	$	3,435,000
Collateralized indebtedness	Level II	1,392,648		1,338,105		1,349,474		1,305,932
Senior guaranteed notes	Level II	3,283,795		3,195,375		2,291,185		2,420,000
Senior notes and debentures	Level II	6,107,472		6,727,849		6,409,889		7,221,846
Notes payable	Level II	36,161		35,962		56,956		55,289
Cablevision senior notes:
Senior notes and debentures	Level II	1,072,340		1,165,034		1,818,115		1,931,239
Cequel debt instruments:
Cequel credit facility debt	Level II	1,244,153		1,252,350		1,250,217		1,258,675
Senior secured notes	Level II	2,572,438		2,535,500		2,570,506		2,658,930
Senior notes	Level II	2,804,435		2,942,800		2,770,737		2,983,615
Notes payable	Level II	36,356		36,356		8,946		8,946
		$	22,985,277	$	23,699,331	$	21,919,331	$	23,279,472

(a) Amounts are net of unamortized deferred financing costs, premiums and discounts.

The fair value estimates related to the Company's debt instruments presented above are made at a specific point in time, based on relevant market information and information about the financial instrument.  These estimates are subjective in nature and involve uncertainties and matters of significant judgments and therefore cannot be determined with precision.  Changes in assumptions could significantly affect the estimates.

NOTE 12.    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

26

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

(Dollars in thousands, except share and per share amounts)

(Unaudited)

income tax expense or benefit associated with these discrete items is fully recognized in the interim period in which the items occur.

The Company recorded income tax benefit of $5,590 and $66,293 for the three and six months ended June 30, 2018, reflecting an effective tax rate of approximately 5% and 23%, respectively. The tax benefit was calculated based upon the actual effective tax rate for the year-to-date period. The Company determined this to represent the best estimate of the annual effective tax rate in light of the magnitude of the expected income and the significant permanent differences.

The Company recorded income tax benefit of $252,487 and $298,395 for the three and six months ended June 30, 2017, reflecting the AETR of approximately 34% and 35%, respectively.

As of June 30, 2018, the Company's federal net operating losses (“NOLs”) were approximately $2,274,000. The utilization of certain pre-merger NOLs of Cablevision and Cequel are limited pursuant to Internal Revenue Code Section 382. The Company does not expect such limitations to impact the ability to utilize the NOLs prior to their expiration.

NOTE 13.    SHARE BASED COMPENSATION

Certain employees of the Company and its affiliates received awards of units in a carry unit plan of Neptune Management LP, an entity which has an ownership interest in the Company. The awards generally vest as follows: 50% on the second anniversary of June 21, 2016 for Cablevision employees or December 21, 2015 for Cequel employees ("Base Date"), 25% on the third anniversary of the Base Date, and 25% on the fourth anniversary of the Base Date.  Neptune Holding US GP LLC, the general partner of Neptune Management LP, has the right to repurchase (or to assign to an affiliate, including the Company, the right to repurchase) vested awards held by employees for sixty days following their termination.  For performance-based awards under the plan, vesting occurs upon achievement or satisfaction of a specified performance condition. The Company considered the probability of achieving the established performance targets in determining the share-based compensation with respect to these awards at the end of each reporting period.

Beginning on the fourth anniversary of the Base Date, the holders of carry units have an annual opportunity (a sixty day period determined by the administrator of the plan) to sell their units back to Neptune Holding US GP LLC (or affiliate, including the Company, designated by Neptune Holding US GP LLC). Accordingly, the carry units are presented as temporary equity on the consolidated balance sheets at fair value. Adjustments to fair value at each reporting period are recorded in paid-in capital.

The right of Neptune Holding US GP LLC to assign to an affiliate, including the Company, the right to repurchase an employee’s vested units during the sixty-day period following termination, or to satisfy its obligation to repurchase an employee’s vested units during annual60day periods following the fourth anniversary of the Base Date, may be exercised by Neptune Holding US GP LLC in its discretion at the time a repurchase right or obligation arises. The carry unit plan requires the purchase price payable to the employee or former employee, as the case may be, to be paid in cash, a promissory note (with a term of not more than3 yearsand bearing interest at the long-term applicable federal rate under Section 1274(d) of the Internal Revenue Code) or combination thereof, in each case as determined by Neptune Holding US GP LLC in its discretion at the time of the repurchase. Neptune Holding US GP LLC expects that vested units will be redeemed for shares of the Company's Class A common stock upon vesting.

The following table summarizes activity relating to carry units:

	Number of Time Vesting Awards		Number of Performance Based Vesting Awards	Weighted Average Grant Date Fair Value
Balance, December 31, 2017	168,550,001		10,000,000	$	0.71
Vested	(43,462,500	)	—	0.37

Balance, June 30, 2018	117,712,500		10,000,000	0.94

The weighted average fair value per unit was $2.14 and $2.50 as of June 30, 2018 and December 31, 2017, respectively. For the three and six months ended June 30, 2018, the Company recognized an expense of $7,993 and $25,494 related to the push down of share-based compensation expense related to the carry unit plan. For the three and six months ended

NOTE 14.    AFFILIATE AND RELATED PARTY TRANSACTIONS

Equity Method Investments

In April 2018, Altice N.V. transferred its ownership of i24 US and i24 Europe ('i24NEWS"), Altice N.V.'s 24/7 international news and current affairs channels to the Company for minimal consideration (the "i24NEWS Acquisition"). As the acquisition was a combination of businesses under common control, the Company combined the results of operations and related assets and liabilities of i24NEWS as of April 1, 2018. Operating results for periods prior to April 1, 2018 and the balance sheet as of December 31, 2017 have not been revised to reflect the combination of i24NEWS as the impact was deemed immaterial.

The Company's equity in the net losses of i24NEWS prior to April 1, 2018 of $1,130 for the six months ended June 30, 2018 and $1,338 and $2,585 for three and six months ended June 30, 2017 were recorded using the equity method and reflected in other expense, net in the Company's statements of operations. The Company's investment in i24NEWS as of December 31, 2017 of $930 is included in investment in affiliates on the Company's condensed consolidated balance sheet.

In April 2018, the Company redeemed a 24% interest in Newsday LLC ("Newsday") and recognized a gain of $13,298, reflected in gain (loss) on investments and sale of affiliate interests, net in the Company's statements of operations.

NOTE 15.    COMMITMENTS AND CONTINGENCIES

Legal Matters

Following expiration of the affiliation agreements for carriage of certain Fox broadcast stations and cable networks on October 16, 2010, News Corporation terminated delivery of the programming feeds to Cablevision, and as a result, those stations and networks were unavailable on Cablevision's cable television systems. On October 30, 2010, Cablevision and Fox reached an agreement on new affiliation agreements for these stations and networks, and carriage was restored. Several purported class action lawsuits alleging breach of contract, unjust enrichment, and consumer fraud and seeking unspecified compensatory damages, punitive damages and attorneys' fees were subsequently filed on behalf of Cablevision's customers seeking recovery for the lack of Fox programming. Those lawsuits were consolidated in an action before the U. S. District Court for the Eastern District of New York, and a consolidated complaint was filed in that court on February 22, 2011. On March 28, 2012, in ruling on Cablevision's motion to dismiss, the Court dismissed all of plaintiffs’ claims, except for breach of contract.  On March 30, 2014, the Court granted plaintiffs’ motion for class certification. The parties have entered into a settlement agreement, which was granted final approval by the Court on May 17, 2018. As of December 31, 2017, the Company had an estimated liability associated with a potential settlement totaling $6,000. The amount ultimately paid in connection with the proposed settlement could exceed the amount recorded.

In October 2015, the New York Attorney General began an investigation into whether the major Internet Service Providers in New York State deliver advertised Internet speeds. The Company is cooperating with this investigation and is currently in discussions with the New York Attorney General about resolving the investigation as to the Company, which resolution

30

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (continued)

(Dollars in thousands, except share and per share amounts)

(Unaudited)

may involve operational and or financial components. While the Company is unable to predict the outcome of the investigation or these discussions, at this time it does not expect that the outcome will have a material adverse effect on its operations, financial conditions or cash flows.

The Company receives notices from third parties and, in some cases, is named as a defendant in certain lawsuits claiming infringement of various patents relating to various aspects of the Company's businesses.  In certain of these cases other industry participants are also defendants.  In certain of these cases the Company expects that any potential liability would be the responsibility of the Company's equipment vendors pursuant to applicable contractual indemnification provisions.  The Company believes that the claims are without merit, but is unable to predict the outcome of these matters or reasonably estimate a range of possible loss.

In addition to the matters discussed above, the Company is party to various lawsuits, some involving claims for substantial damages.  Although the outcome of these other matters cannot be predicted and the impact of the final resolution of these other 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 other lawsuits will have a material adverse effect on the financial position of the Company or the ability of the Company to meet its financial obligations as they become due.

NOTE 16.    SEGMENT INFORMATION

The Company classifies its operations into two reportable segments: Cablevision and Cequel. The Company's reportable segments are strategic business units that are managed separately.  The Company evaluates segment performance based on several factors, of which the primary financial measure is business segment Adjusted EBITDA, a non-GAAP measure.  The Company defines Adjusted EBITDA as net income (loss) excluding income taxes, income (loss) from discontinued operations, non-operating other income or expenses, loss on extinguishment of debt and write-off of deferred financing costs, gain (loss) on interest rate swap contracts, gain (loss) on derivative contracts, gain (loss) on investments, interest expense (including cash interest expense), interest income, depreciation and amortization (including impairments), share-based compensation expense or benefit, restructuring expense or credits and transaction expenses.  The Company has presented the components that reconcile Adjusted EBITDA to operating income, an accepted GAAP measure:

Item 2.         Management's Discussion and Analysis of Financial Condition and Results of Operations

All dollar amounts, except per customer and per share data, included in the following discussion, are presented in thousands.

The preparation of our condensed consolidated financial statements requires us to make estimates that affect the reported amounts of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and contingent liabilities. For a complete discussion of the accounting judgments and estimates that we have identified as critical in the preparation of our condensed consolidated financial statements, please refer to our Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2017 Annual Report on Form 10-K.

Overview

Our Business

We deliver broadband, pay television, telephony services, proprietary content and advertising services to approximately 4.9 million residential and business customers. Our footprint extends across 21 states through a fiber‑rich broadband network with approximately 8.7 million homes passed as of June 30, 2018. We have two reportable segments: Cablevision and Cequel. Cablevision provides broadband, pay television and telephony services to residential and business customers in and around the New York metropolitan area. Cequel provides broadband, pay television and telephony services to residential and business customers in the south‑central United States, with the majority of its customers located in the ten states of Texas, West Virginia, Louisiana, Arkansas, North Carolina, Oklahoma, Arizona, California, Missouri and Ohio.

Key Factors Impacting Operating Results and Financial Condition

Our future performance is dependent, to a large extent, on the impact of direct competition, general economic conditions (including capital and credit market conditions), our ability to manage our businesses effectively, and our relative strength and leverage in the marketplace, both with suppliers and customers. For more information see “Risk Factors” and “Business-Competition” included in our Annual Report on Form 10-K for the year ended December 31, 2017.

We derive revenue principally through monthly charges to residential subscribers of our pay television, broadband, and telephony services. We also derive revenue from DVR, VOD, pay‑per‑view, installation and home shopping commissions. Our residential pay television, broadband and telephony services accounted for approximately 44%, 30% and 7%, respectively, of our consolidated revenue for the six months ended June 30, 2018. We also derive revenue from the sale of a wide and growing variety of products and services to both large enterprise and SMB customers, including broadband, telephony, networking and pay television services. For the six months ended June 30, 2018, 14% of our consolidated revenue was derived from these business services and wholesale. In addition, we derive revenues from the sale of advertising time available on the programming carried on our cable television systems, which accounted for approximately 4% of our consolidated revenue for the six months ended June 30, 2018. Our other revenue for the six months ended June 30, 2018 accounted for less than 1% of our consolidated revenue.

Revenue is impacted by rate increases, changes in the number of customers to our services, including additional services sold to our existing customers, programming package changes by our pay television customers, speed tier changes by our broadband customers, and acquisitions of cable systems that result in the addition of new subscribers.

Our ability to increase the number of customers to our services is significantly related to our penetration rates.

We operate in a highly competitive consumer‑driven industry and we compete against a variety of broadband, pay television and telephony providers and delivery systems, including broadband communications companies, wireless data and telephony providers, satellite‑delivered video signals, Internet‑delivered video content and broadcast television signals available to residential and business customers in our service areas. Our competitors include AT&T and its DirecTV subsidiary, CenturyLink, DISH Network, Frontier and Verizon. Consumers’ selection of an alternate source of service, whether due to economic constraints, technological advances or preference, negatively impacts the demand for our services. For more information on our competitive landscape, see “Risk Factors” and “Business-Competition” included our Annual Report on Form 10-K for the year ended December 31, 2017.

Our programming costs, which are the most significant component of our operating expenses, have increased and are expected to continue to increase primarily as a result of contractual rate increases and new channel launches. See “-

34

Results of Operations” below for more information regarding our key factors impacting our revenues and operating expenses.

Historically, we have made substantial investments in our network and the development of new and innovative products and other service offerings for our customers as a way of differentiating ourselves from our competitors and may continue to do so in the future. We have commenced construction on a fiber-to-the-home ("FTTH") network, which will enable us to deliver more than 10 Gbps broadband speeds across our entire Optimum footprint and part of our Suddenlink footprint. We may incur greater than anticipated capital expenditures in connection with this initiative, fail to realize anticipated benefits, experience delays and business disruptions or encounter other challenges to executing it as planned. See “Liquidity and Capital Resources-Capital Expenditures” for additional information regarding our capital expenditures.

Acquisition of Altice Technical Services US Corp

As discussed in Note 1 of the Company's condensed consolidated financial statements, the Company completed the ATS Acquisition in January 2018. ATS was previously owned by Altice N.V. and a member of ATS's management through a holding company. As the acquisition is a combination of businesses under common control, the Company combined the results of operations and related assets and liabilities of ATS for all periods since the formation of ATS.

Acquisition of i24NEWS

In April 2018, the Company and Altice N.V. completed the i24NEWS Acquisition. As the acquisition was a combination of businesses under common control, the Company combined the results of operations and related assets and liabilities of i24NEWS as of April 1, 2018. Operating results for periods prior to April 1, 2018 and the balance sheet as of December 31, 2017 have not been revised to reflect the combination of i24NEWS as the impact was deemed immaterial.

Non-GAAP Financial Measures

We define Adjusted EBITDA, which is a non-GAAP financial measure, as net income (loss) excluding income taxes, income (loss) from discontinued operations, other non-operating income or expenses, loss on extinguishment of debt and write-off of deferred financing costs, gain (loss) on interest rate swap contracts, gain (loss) on derivative contracts, gain (loss) on investments, interest expense (including cash interest expense), interest income, depreciation and amortization (including impairments), share-based compensation expense or benefit, restructuring expense or credits and transaction expenses. We believe Adjusted EBITDA is an appropriate measure for evaluating the operating performance of the Company. Adjusted EBITDA and similar measures with similar titles are common performance measures used by investors, analysts and peers to compare performance in our industry. Internally, we use revenue and Adjusted EBITDA measures as important indicators of our business performance, and evaluate management’s effectiveness with specific reference to these indicators. We believe Adjusted EBITDA provides management and investors a useful measure for period-to-period comparisons of our core business and operating results by excluding items that are not comparable across reporting periods or that do not otherwise relate to the Company’s ongoing operating results. Adjusted EBITDA should be viewed as a supplement to and not a substitute for operating income (loss), net income (loss), and other measures of performance presented in accordance with GAAP. Since Adjusted EBITDA is not a measure of performance calculated in accordance with GAAP, this measure may not be comparable to similar measures with similar titles used by other companies.

(a) Represents the estimated number of single residence homes, apartments and condominium units passed by the cable distribution network in areas serviceable without further extending the transmission lines. In addition, it includes commercial establishments that have connected to our cable distribution network. For Cequel, broadband services were not available to approximately 100 homes passed and telephony services were not available to approximately 500 homes passed.

(b) Represents number of households/businesses that receive at least one of the Company's services.

(c) Customers represent each customer account (set up and segregated by customer name and address), weighted equally and counted as one customer, regardless of size, revenue generated, or number of boxes, units, or outlets.  In calculating the

37

number of customers, we count all customers other than inactive/disconnected customers.  Free accounts are included in the customer counts along with all active accounts, but they are limited to a prescribed group.  Most of these accounts are also not entirely free, as they typically generate revenue through pay-per-view or other pay services and certain equipment fees.  Free status is not granted to regular customers as a promotion.  In counting bulk residential customers, such as an apartment building, we count each subscribing family unit within the building as one customer, but do not count the master account for the entire building as a customer. We count a bulk commercial customer, such as a hotel, as one customer, and do not count individual room units at that hotel.

(d) Represents the number of customers that subscribe to three of our services divided by total residential customer relationships.

(e) Represents the number of total customer relationships divided by homes passed.

(f) Calculated by dividing the average monthly revenue for the respective quarter (fourth quarter for annual periods) derived from the sale of broadband, pay television and telephony services to residential customers for the respective quarter by the average number of total residential customers for the same period.

Altice USA - Comparison of Results for the Three and Six Months Ended June 30, 2018 compared to the Three and Six Months Ended June 30, 2017.

Pay Television Revenue

Pay television revenue for the three and six months ended June 30, 2018 was $1,034,404 and $2,068,112, respectively, of which $766,257 and $1,529,977 was derived from the Cablevision segment and $268,147 and $538,135 relates to our Cequel segment. Pay television revenue for the three and six months ended June 30, 2017 was $1,071,163 and $2,155,041, respectively, of which $796,456 and $1,598,650 was derived from the Cablevision segment and $274,707 and $556,391 relates to our Cequel segment. Pay television revenue is derived principally through monthly charges to residential customers of our pay television services. Revenue is impacted by rate increases, changes in the number of customers, including additional services sold to our existing customers, and changes in programming packages.

Pay television revenue for our Cablevision segment decreased $30,199 (4%) and $68,673 (4%) for the three and six months ended June 30, 2018 as compared to the three and six months ended June 30, 2017, respectively. The decreases were due primarily due to a decline in pay television customers and lower average revenue per pay television customer.

Pay television revenue for our Cequel segment decreased $6,560 (2%) and $18,256 (3%) for the three and six months ended June 30, 2018 as compared to the three and six months ended June 30, 2017, respectively. The decreases were due primarily to a decline in the number of pay television customers, partially offset by an increase in average revenue per pay television customer.

We believe our pay television customer declines noted in the table above are largely attributable to competition, particularly from Verizon in our Cablevision footprint and DBS providers in our Cequel footprint, as well as competition from companies that deliver video content over the Internet directly to customers. These factors are expected to continue to impact our ability to maintain or increase our existing customers and revenue in the future.

Programming and other direct costs include cable programming costs, which are costs paid to programmers (net of amortization of any incentives received from programmers for carriage) for cable content (including costs of VOD and pay‑per‑view) and are generally paid on a per‑customer basis. These costs typically rise due to increases in contractual rates and new channel launches and are also impacted by changes in the number of customers receiving certain programming services. These costs also include interconnection, call completion, circuit and transport fees paid to other telecommunication companies for the transport and termination of voice and data services, which typically vary based on rate changes and the level of usage by our customers. These costs also include franchise fees which are payable to the state governments and local municipalities where we operate and are primarily based on a percentage of certain categories of revenue derived from the provision of pay television service over our cable systems, which vary by state and municipality. These costs change in relation to changes in such categories of revenues or rate changes.

The increases of $36,433 (5%) and $65,442 (4%) in programming and other direct costs for the three and six months ended June 30, 2018, net of inter-segment eliminations, as compared to the prior year periods are attributable to the following:

Cablevision segment:	Three Months			Six Months
Increase in costs of digital media and linear advertising spots for resale	$	14,248		$	28,274
Increase in programming costs due primarily to contractual rate increases, partially offset by lower pay television customers and lower video-on-demand and pay-per-view costs	10,082			14,557
Other net decreases (including an increase of $1,266 in costs related to i24NEWS)	(3,423		)	(1,654		)
	20,907			41,177

Cequel segment:
Increase in programming costs due primarily to contractual rate increases and new channel launches, partially offset by lower pay television customers and lower video-on-demand and pay-per-view costs	18,503			30,222
Other net increases	1,045			1,909
	19,548			32,131
Inter-segment eliminations	(4,022		)	(7,866		)
	$	36,433		$	65,442

Other operating expenses include staff costs and employee benefits including salaries of company employees and related taxes, benefits and other employee related expenses, as well as third party labor costs. Other operating expenses also include network management and field service costs, which represent costs associated with the maintenance of our broadband network, including costs of certain customer connections and other costs associated with providing and maintaining services to our customers.

Customer installation and repair and maintenance costs may fluctuate as a result of changes in the level of activities and the utilization of contractors as compared to employees. Also, customer installation costs fluctuate as the portion of our expenses that we are able to capitalize changes. Costs associated with the initial deployment of new customer premise equipment necessary to provide broadband, pay television and telephony services are capitalized (asset-based). Network repair and maintenance and utility costs also fluctuate as capitalizable network upgrade and enhancement activity changes.

Other operating expenses also include costs related to the operation and maintenance of our call center facilities that handle customer inquiries and billing and collection activities and sales and marketing costs, which include advertising production and placement costs associated with acquiring and retaining customers. These costs vary period to period and certain of these costs, such as sales and marketing, may increase with intense competition. Additionally, other operating expenses include various other administrative costs, including legal fees, and product development costs.

These amounts primarily relate to costs incurred in connection with severance and other employee related costs resulting from headcount reductions related to initiatives which commenced in 2016 that are intended to simplify the Company's organizational structure. We currently anticipate that additional restructuring expenses will be recognized as we continue to analyze our organizational structure.

Adjusted EBITDA is a non-GAAP measure that is defined as net income (loss) excluding income taxes, income (loss) from discontinued operations, non-operating income or expenses, loss on extinguishment of debt and write-off of deferred financing costs, gain (loss) on interest rate swap contracts, gain (loss) on derivative contracts, gain (loss) on investments, interest expense (including cash interest expense), interest income, depreciation and amortization (including impairments), share-based compensation expense or benefit, restructuring expense or credits and transaction expenses. See reconciliation of net loss to adjusted EBITDA above.

The increases in adjusted EBITDA of our Cablevision segment for the three months ended June 30, 2018 as compared to the prior year periods were due to an increase in revenue, partially offset by an increase in operating expenses (excluding depreciation and amortization expense, restructuring expense, share-based compensation and transaction expenses) as discussed above. The increases in adjusted EBITDA of our Cablevision segment for the six months ended June 30, 2018 as compared to the prior year periods were due to an increase in revenue and a decrease in operating expenses (excluding depreciation and amortization expense, restructuring expense, share-based compensation and transaction expenses).

The decreases in adjusted EBITDA of our Cequel segment for the three and six months ended June 30, 2018 as compared to the prior year periods were due primarily to an increase in operating expenses (excluding depreciation and amortization expense, restructuring expense, share-based compensation and transaction expenses), partially offset by an increase in revenue as discussed above.

Liquidity and Capital Resources

Altice USA has no operations independent of its subsidiaries, Cablevision and Cequel. Funding for our subsidiaries has generally been provided by cash flow from their respective operations, cash on hand and borrowings under their revolving credit facilities and the proceeds from the issuance of securities and borrowings under syndicated term loans in the capital markets.  Our decision as to the use of cash generated from operating activities, cash on hand, borrowings under the revolving credit facilities or accessing the capital markets has been based upon an ongoing review of the funding needs of the business, the optimal allocation of cash resources, the timing of cash flow generation and the cost of borrowing under the revolving credit facilities, debt securities and syndicated term loans. We manage our business to a long-term net leverage ratio target of 4.5x to 5.0x. We calculate our consolidated net leverage ratio as net debt to L2QA EBITDA (Adjusted EBITDA for the two most recent consecutive fiscal quarters multiplied by 2.0).

We expect to utilize free cash flow and availability under the revolving credit facilities, as well as future refinancing transactions, to further extend the maturities of, or reduce the principal on, our debt obligations. The timing and terms of any refinancing transactions will be subject to, among other factors, market conditions. Additionally, we may, from time to time, depending on market conditions and other factors, use cash on hand and the proceeds from other borrowings to repay the outstanding debt securities through open market purchases, privately negotiated purchases, tender offers, or redemptions.

44

We believe existing cash balances, operating cash flows and availability under our revolving credit facilities will provide adequate funds to support our current operating plan, make planned capital expenditures and fulfill our debt service requirements for the next twelve months. However, our ability to fund our operations, make planned capital expenditures, make scheduled payments on our indebtedness and repay our indebtedness depends on our future operating performance and cash flows and our ability to access the capital markets, which, in turn, are subject to prevailing economic conditions and to financial, business and other factors, some of which are beyond our control. Our collateralized debt maturing in the next 12 months will be settled with proceeds from monetization contracts entered into pursuant to the Synthetic Monetization Closeout discussed below. However, competition, market disruptions or a deterioration in economic conditions could lead to lower demand for our products, as well as lower levels of advertising, and increased incidence of customers' inability to pay for the services we provide.  These events would adversely impact our results of operations, cash flows and financial position.  Although we currently believe that amounts available under the revolving credit facilities will be available when, and if, needed, we can provide no assurance that access to such funds will not be impacted by adverse conditions in the financial markets or other conditions.  The obligations of the financial institutions under the revolving credit facilities are several and not joint and, as a result, a funding default by one or more institutions does not need to be made up by the others.

In the longer term, we do not expect to be able to generate sufficient cash from operations to fund anticipated capital expenditures, meet all existing future contractual payment obligations and repay our debt at maturity.  As a result, we will be dependent upon our continued access to the capital and credit markets to issue additional debt or equity or refinance existing debt obligations.  We intend to raise significant amounts of funding over the next several years to fund capital expenditures, repay existing obligations and meet other obligations, and the failure to do so successfully could adversely affect our business.  If we are unable to do so, we will need totake other actions including deferring capital expenditures, selling assets, seeking strategic investments from third parties or reducing or eliminating discretionary uses of cash.

In 2017, the Company's financing activities consisted primarily of proceeds from credit facility debt of $4,977,425 and collateralized indebtedness of $490,816, proceeds from IPO, net of fees of $349,156, and contributions from noncontrolling interests of $51,135, partially offset by repayments of credit facility debt of $3,573,750, redemption of senior notes, including premiums and fees of $979,280, dividends to stockholders of $919,317, repayments of collateralized indebtedness and related derivative contracts of $483,081, principal payments on capital lease obligations of $8,061 and additions to deferred financing costs of $7,352.

Settlements of Collateralized Indebtedness

The following table summarizes the settlement of the Company's collateralized indebtedness relating to Comcast shares that were settled by delivering cash equal to the collateralized loan value, net of the value of the related equity derivative contracts during the six months ended June 30, 2018: 

Number of shares (a)	10,802,118
Collateralized indebtedness settled	$	(337,148	)
Derivatives contracts settled	24
	(337,124		)
Proceeds from new monetization contracts	337,124
Net cash proceeds	$	—

The cash to settle the collateralized indebtedness was obtained from the proceeds of new monetization contracts covering an equivalent number of Comcast shares.  The terms of the new contracts allow the Company to retain upside participation in Comcast shares up to each respective contract's upside appreciation limit with downside exposure limited to the respective hedge price. 

In April 2017, the Company entered into new monetization contracts related to 32,153,118 shares of Comcast common stock held by Cablevision, which synthetically reversed the existing contracts related to these shares (the "Synthetic Monetization Closeout"). As the existing collateralized debt matures, the Company will settle the contracts with proceeds received from the new monetization contracts. The new monetization contracts mature on April 28, 2021. The new monetization contracts provide the Company with downside protection below the hedge price of $35.47 and upside benefit of stock price appreciation up to $44.72 per share.

Commitments and Contingencies

As of June 30, 2018, the Company's commitments and contingencies not reflected in the Company's balance sheet decreased to approximately $7,872,000 as compared to approximately $9,069,000 at December 31, 2017. This decrease relates primarily to payments made pursuant to programming commitments, offset by renewed multi-year programming agreements entered into during the six months ended June 30, 2018.

Recently Issued But Not Yet Adopted Accounting Pronouncements

In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017‑04, Intangibles-Goodwill and Other (Topic 350). ASU No. 2017‑04 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. ASU No. 2017‑04 becomes effective for the Company on January 1, 2020 with early adoption permitted and will be applied prospectively.

In February 2016, the FASB issued ASU No. 2016-02, Leases, which increases transparency and comparability by recognizing a lessee’s rights and obligations resulting from leases by recording them on the balance sheet as lease assets and lease liabilities. The new guidance becomes effective for the Company on January 1, 2019 with early adoption permitted and will be applied using the modified retrospective method. Although, the Company has not yet completed the evaluation of the effect that ASU No. 2016-02 will have on its consolidated financial statements, upon adoption, the Company expects to recognize a right of use asset and liability related to substantially all operating lease arrangements on the Company's consolidated balance sheet.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

All dollar amounts, except per share data, included in the following discussion are presented in thousands.

Equity Price Risk

We are exposed to market risks from changes in certain equity security prices.  Our exposure to changes in equity security prices stems primarily from the shares of Comcast common stock we hold.  We have entered into equity derivative contracts consisting of a collateralized loan and an equity collar to hedge our equity price risk and to monetize the value of these securities.  These contracts, at maturity, are expected to offset declines in the fair value of these securities below the hedge price per share while allowing us to retain upside appreciation from the hedge price per share to the relevant cap price.  The contracts' actual hedge prices per share vary depending on average stock prices in effect at the time the contracts were executed.  The contracts' actual cap prices vary depending on the maturity and terms of each contract, among other factors.  If any one of these contracts is terminated prior to its scheduled maturity date due to the occurrence of an event specified in the contract, we 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 June 30, 2018, we did not have an early termination shortfall relating to any of these contracts.

The underlying stock and the equity collars are carried at fair value on our condensed consolidated balance sheet and the collateralized indebtedness is carried at its principal value, net of discounts and the unamortized fair value adjustment for contracts that existed at the date of the Cablevision Acquisition. The fair value adjustment is being amortized over the term of the related indebtedness.  The carrying value of our collateralized indebtedness amounted to $1,392,648 at June 30, 2018.  At maturity, the contracts provide for the option to deliver cash or shares of Comcast common stock, with a value determined by reference to the applicable stock price at maturity.

As of June 30, 2018, the fair value and the carrying value of our holdings of Comcast common stock aggregated $1,409,361.  Assuming a 10% change in price, the potential change in the fair value of these investments would be approximately $140,936.  As of June 30, 2018, the net fair value and the carrying value of the equity collar component of the equity derivative contracts entered into to partially hedge the equity price risk of our holdings of Comcast common stock aggregated $101,007, a net asset position.  For the three and six months ended June 30, 2018, we recorded a net gain of $42,159 and $210,511, respectively, related to our outstanding equity derivative contracts and recorded an unrealized loss of $58,420 and $310,996, respectively, related to the Comcast common stock that we held.

Fair Value of Equity Derivative Contracts
Fair value as of December 31, 2017, net liability position	$	(109,504	)
Change in fair value, net	210,511
Fair value as of June 30, 2018, net asset position	$	101,007

The maturity, number of shares deliverable at the relevant maturity, hedge price per share, and the lowest and highest cap prices received for the Comcast common stock monetized via an equity derivative prepaid forward contract are summarized in the following table:

		Hedge Price	Cap Price (b)
# of Shares Deliverable (a)	Maturity	per Share (a)	Low		High
5,337,750	2018	$33.61	$	40.33	$	40.33
37,617,486	2021	$29.25- $35.47	$	43.88	$	44.80

(a) Represents the price below which we are provided with downside protection and above which we retain upside appreciation.  Also represents the price used in determining the cash proceeds payable to us at inception of the contracts.

(b) Represents the price up to which we receive the benefit of stock price appreciation.

52

Fair Value of Debt

At June 30, 2018, the fair value of our fixed rate debt of $17,976,981 was higher than its carrying value of $17,305,645 by $671,336.  The fair value of these financial instruments is estimated based on reference to quoted market prices for these or comparable securities.  Our floating rate borrowings bear interest in reference to current LIBOR-based market rates and thus their principal values approximate fair value.  The effect of a hypothetical 100 basis point decrease in interest rates prevailing at June 30, 2018 would increase the estimated fair value of our fixed rate debt by $619,120 to $18,596,101. This estimate is based on the assumption of an immediate and parallel shift in interest rates across all maturities.

Interest Rate Risk

In May 2018, the Company entered into two interest rate swap contracts whereby one contract converts the interest rate on $2,970,000 of the CSC Holdings Term Loan Facility from a one-month LIBO rate to a three-month LIBO rate minus 0.226% and the second contract converts the interest rate on $1,496,250 of the CSC Holdings Incremental Term Loan from a one month LIBO rate to a three-month LIBO rate minus 0.226%. The objective of these swaps is to potentially pay a lower interest rate than what the Company can elect under the terms of the CSC Holdings Credit Facilities Agreement.

In April 2018, the Company entered into an interest rate swap contract which converts the interest rate on $1,255,513 of the Cequel Term Loan B from a one month LIBO rate to a three-month LIBO rate minus 0.225%. The objective of this swap is to potentially pay a lower interest rate than what the Company can elect under the terms of the Cequel Credit Facilities Agreement.

In June 2016, a subsidiary of Cequel entered into two fixed to floating interest rate swaps. One fixed to floating interest rate swap is converting $750,000 from a fixed rate of 1.6655% to six-month LIBOR and a second tranche of $750,000 from a fixed rate of 1.68% to six-month LIBOR. The objective of these swaps is to adjust the proportion of total debt that is subject to fixed and variable interest rates.

These swap contracts are not designated as hedges for accounting purposes. Accordingly, the changes in the fair value of these interest rate swap contracts are recorded through the statement of operations. For the three and six months ended June 30, 2018, the Company recorded a loss on interest rate swap contracts of $12,929 and $44,851, respectively.

As of June 30, 2018, our outstanding interest rate swap contracts in a liability position had an aggregate fair value and carrying value of $123,470 reflected in “Liabilities under derivative contracts” on our condensed consolidated balance sheet. Our outstanding interest rate swap contracts in an asset position had an aggregate fair value and carrying value of $369 reflected in “Derivative contracts” in our condensed consolidated balance sheet.

We do not hold or issue derivative instruments for trading or speculative purposes.

Item 4.        Controls and Procedures

Evaluation of Disclosure Controls and Procedures

An evaluation was carried out under the supervision and with the participation of Altice USA's management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined under SEC rules).  Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the design and operation of these disclosure controls and procedures were effective as of June 30, 2018.

Changes in Internal Control

During the six months ended June 30, 2018, there were no changes in the Company's internal control over financial reporting that materially affected or are reasonably likely to materially affect the Company's internal control over financial reporting.

The Company plans to migrate Cequel’s customer billing system to the Cablevision billing system platform in 2018. Additionally, the Company plans to implement and upgrade certain other customer billing systems.

DESCRIPTION OF BUSINESS AND RELATED MATTERS

DESCRIPTION OF BUSINESS AND RELATED MATTERS

The Company and Related Matters

Altice USA, Inc. ("Altice USA" or the "Company") was incorporated in Delaware on September 14, 2015. Prior to the Altice N.V. distribution discussed below, Altice USA was majority‑owned by Altice N.V., a public company with limited liability (naamloze vennootshcap) under Dutch law. Since the completion of the Altice N.V. distribution discussed below, the Company is no longer majority-owned by Altice N.V.

The Company provides broadband communications and video services in the United States. It delivers broadband, pay television, telephony services, proprietary content and advertising services to residential and business customers.

Altice N.V., through a subsidiary, acquired Cequel Corporation ("Cequel" or "Suddenlink") 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" or "Optimum") on June 21, 2016 (the "Cablevision Acquisition").

The Company classifies its operations into two reportable segments: Cablevision, which operates in the New York metropolitan area, and Cequel, which principally operates in markets in the south‑central United States.

The accompanying condensed combined consolidated financial statements ("condensed consolidated financial statements") include the accounts of the Company and all subsidiaries in which the Company has a controlling interest and gives effect to the ATS Acquisition and the i24 Acquisition discussed below on a combined basis. All significant inter-company accounts and transactions have been eliminated in consolidation.

The accompanying condensed consolidated operating results for the three and six months ended June 30, 2017 reflect the retrospective adoption of Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers and ASU No. 2017‑07 Compensation-Retirement Benefits (Topic 715). See Note 3 for further details of the impact on the Company's historical financial statements.

In June 2017, the Company completed its initial public offering ("IPO") of 71,724,139 shares of its Class A common stock. The Company’s Class A common stock began trading on June 22, 2017, on the New York Stock Exchange under the symbol "ATUS".

Acquisition of Altice Technical Services US Corp

ATS was formed in 2017 to provide network construction and maintenance services and commercial and residential installations, disconnections, and maintenance. During the second quarter of 2017, a substantial portion of the Company's technical workforce at the Cablevision segment either accepted employment with ATS or became employees of ATS and ATS commenced operations and began to perform services for the Company. A substantial portion of the Cequel segment technical workforce became employees of ATS in December 2017.

In January 2018, the Company acquired 70% of the equity interests in Altice Technical Services US Corp. ("ATS") for $1.00 (the "ATS Acquisition") and the Company became the owner of 100% of the equity interests in ATS in March 2018. ATS was previously owned by Altice N.V. and a member of ATS's management through a holding company. As the acquisition was a combination of businesses under common control, the Company combined the results of operations and related assets and liabilities of ATS for all periods since its formation. See Note 3 for the impact of the ATS Acquisition on the Company's condensed consolidated balance sheet as of December 31, 2017 and on the Company's statement of operations for the three and six months ended June 30, 2017.

Acquisition of i24NEWS

In April 2018, Altice N.V. transferred its ownership of i24 US and i24 Europe ("i24NEWS"), Altice N.V.'s 24/7 international news and current affairs channels to the Company for minimal consideration (the "i24 Acquisition"). As the acquisition was a combination of businesses under common control, the Company combined the results of operations and related assets and liabilities of i24NEWS as of April 1, 2018. Operating results for periods prior to April 1, 2018 and the balance sheet as of December 31, 2017 have not been revised to reflect the i24 Acquisition as the impact was deemed immaterial.

Altice N.V. Distribution

On June 8, 2018, Altice N.V. distributed substantially all of its equity interest in the Company through a distribution in kind to holders of Altice N.V.'s common shares A and common shares B (the “Distribution”). The Distribution took place by way of a special distribution in kind by Altice N.V. of its 67.2% interest in the Company to Altice N.V. shareholders. Each shareholder of Altice N.V. on May 23, 2018, the Distribution record date, received 0.4163 shares of the Company's common stock for every share held by such shareholder in Altice N.V. Between May 24, 2018 and June 4, 2018, each Altice N.V. shareholder was given the opportunity to elect the percentage of shares of the Company's Class A common stock and shares of the Company's Class B common stock such shareholder would receive in the Distribution, whereby the number of shares of the Company's Class B common stock to be distributed was subject to a cap of 50% of the total shares of the Company's common stock being distributed (the “Class B Cap”). Because the Class B Cap had been exceeded, the shares of the Company's Class B common stock delivered to Altice N.V.’s shareholders of record who elected to receive them were subject to proration, and such shareholders received shares of the Company's Class A common stock.

Immediately following the Distribution, there were 489,384,523 shares of Altice USA Class A common stock and 247,684,443 shares of Altice USA Class B common stock outstanding.

Prior to Altice N.V.'s announcement of the Distribution, the Board of Directors of Altice USA, acting through its independent directors, approved the payment of a $2.035 dividend to all shareholders of record on May 22, 2018. The payment of the dividend, aggregating $1,499,935, was made on June 6, 2018, and wasfunded with cash at CSC Holdings LLC, a wholly-owned subsidiary of Cablevision, from financings completed in January 2018 and cash generated from operations at Cequel. In connection with the payment of the dividend, the Company recorded a decrease in retained earnings of $536,224, representing the cumulative earnings through the payment date, and a decrease in paid in capital of $963,711.

In addition, the Board of Directors of Altice USA also authorized a share repurchase program of $2.0 billion, effective June 8, 2018.

In connection with the Distribution, the Management Advisory and Consulting Services Agreement with Altice N.V. which provided certain consulting, advisory and other services was terminated. Compensation under the terms of the agreement was an annual fee of $30,000 paid by the Company.

Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accompanying unaudited condensed 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 condensed 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, 2017 and the Company's financial statements and notes thereto included on Form 8-K filed on May 21, 2018.

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, 2018.

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.

Recently Adopted Accounting Pronouncements

In February 2018, the FASB issued ASU No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The primary provision of ASU No. 2018-02 allows for the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. ASU No. 2018-02 also requires certain disclosures about stranded tax effects. ASU No. 2018‑02 is effective for the Company on January 1, 2019, with early adoption permitted and will be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company elected to adopt ASU No. 2018-02 during the first quarter of 2018. The adoption resulted in the reclassification of stranded tax amounts of $2,163 associated with net unrecognized losses from the Company's pension plans from accumulated other comprehensive loss to retained earnings.

In May 2017, the FASB issued ASU No. 2017-09, Compensation- Stock Compensation (Topic 718). ASU No. 2017‑09 provides clarity and guidance on which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU No. 2017‑09 was adopted by the Company on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits (Topic 715). ASU No. 2017‑07 requires that an employer disaggregate the service cost component from the other components of net benefit cost. It also provides guidance on how to present the service cost component and the other components of net benefit cost in the income statement and what component of net benefit cost is eligible for capitalization. ASU No. 2017‑07 was adopted by the Company on January 1, 2018 and was applied retrospectively. As a result of the adoption, the Company reclassified the non-service cost components of the Company's pension expense for the three and six months ended March 31, 2017 from other operating expenses to other income (expense), net. The Company elected to apply the practical expedient which allowed it to reclassify amounts disclosed previously in the benefits plan note as the basis for applying retrospective presentation for comparative periods, as the Company determined it was impracticable to disaggregate the cost components for amounts capitalized and amortized in those periods. See Note 3 for information on the impact of the adoption of ASU No. 2017-07.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business, which amends Topic 805 to interpret the definition of a business by adding guidance to assist in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company adopted the new guidance on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities.  ASU No. 2016-01 modifies how entities measure certain equity investments and also modifies the recognition of changes in the fair value of financial liabilities measured under the fair value option. Entities will be required to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income. For financial liabilities measured using the fair value option, entities will be required to record changes in fair value caused by a change in instrument-specific credit risk (own credit risk) separately in other comprehensive income. ASU No. 2016-01 was adopted by the Company on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ("ASC 606"), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASC 606 replaced most existing revenue recognition guidance in GAAP and allowed the use of either the retrospective or cumulative effect transition method.

In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, in order to clarify the Codification and to correct any unintended application of the guidance. The amendments in this update affected the guidance in ASC 606. ASC 606 was adopted by the Company on January 1, 2018 on a full retrospective basis, which required the Company to reflect the impact of the updated guidance for all periods presented. The adoption of ASC 606 did not have a material impact on the Company’s financial position or results of operations. See Note 3 for information on the impact of the adoption of ASC 606.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. ASU No. 2016-15 also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The Company adopted the new guidance on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

Recently Issued But Not Yet Adopted Accounting Pronouncements

In January 2017, the FASB issued ASU No. 2017‑04, Intangibles-Goodwill and Other (Topic 350). ASU No. 2017‑04 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. ASU No. 2017‑04 becomes effective for the Company on January 1, 2020 with early adoption permitted and will be applied prospectively.

In February 2016, the FASB issued ASU No. 2016-02, Leases, which increases transparency and comparability by recognizing a lessee’s rights and obligations resulting from leases by recording them on the balance sheet as lease assets and lease liabilities. The new guidance becomes effective for the Company on January 1, 2019. Although, the Company has not yet completed the evaluation of the effect that ASU No. 2016-02 will have on its consolidated financial statements, upon adoption, the Company expects to recognize a right of use asset and liability related to substantially all operating lease arrangements on the Company's consolidated balance sheet.

Adoption of ASC 606 - Revenue from Contracts with Customers

On January 1, 2018, the Company adopted the guidance pursuant to ASC 606. The Company elected to apply the guidance on a full retrospective basis, which required the Company to reflect the impact of the updated guidance for all periods presented. The adoption of the guidance resulted in the deferral of certain installation revenue, the deferral of certain commission expenses, and a reduction of revenue due to the reclassification of certain third party giveaways and incentives from operating expense. Additionally, the Company made changes in the composition of revenue resulting from the allocation of value related to bundled services sold to residential customers at a discount.

Installation Services Revenue

Pursuant to ASC 606, the Company's installation services revenue is deferred and recognized over the benefit period. For residential customers, the benefit period is less than one year. For business and wholesale customers, the benefit period is the contract term. Prior to the adoption of ASC 606, the Company recognized installation services revenue for residential and small and medium-sized business ("SMB") customers when installations were completed. As a result of the deferral of installation services revenue for residential and SMB customers, the Company recognized contract liabilities of $6,978 and recorded a cumulative effect adjustment of $5,093 (net of tax of $1,885) to retained earnings. The accounting for installation services revenue related to business and wholesale customers has not changed.

Commission Expenses

Pursuant to ASC 606, the Company defers commission expenses related to obtaining a contract with a customer when the expected period of benefit is greater than one year and amortizes these costs over the average contract term. For commission expenses related to customer contracts with a term of one year or less, the Company is utilizing the practical expedient and is recognizing the costs when incurred.  Prior to the adoption of ASC 606, the Company recognized commission expenses related to the sale of its services when incurred. As a result of the change in the timing of recognition of these commission expenses, the Company recognized contract assets of $24,329 and recorded a cumulative effect adjustment of $17,759 (net of tax of $6,570) to retained earnings.

Third Party Product Giveaways and Incentives

When the Company acts as the agent in providing certain product giveaways or incentives, revenue is recorded net of the costs of the giveaways and incentives. For the three and six months ended June 30, 2017, costs of $5,979 and $9,396, respectively for the giveaways and incentives recorded in other operating expense have been reclassified to revenue.

Bundled Services

The Company provides bundled services at a discounted rate to its customers. Under ASC 606, revenue should be allocated to separate performance obligations within a bundled offering based on the relative stand-alone selling price of each service within the bundle.In connection with the adoption of ASC 606, the Company revised the amounts allocated to each performance obligation within its bundled offerings which reduced previously reported revenue for telephony services and increased previously reported revenue allocated to pay television and broadband services.

Adoption of ASU No. 2017-07 - Compensation-Retirement Benefits (Topic 715)

On January 1, 2018, the Company adopted the guidance pursuant to ASU No. 2017‑07. ASU No. 2017‑07 requires that an employer disaggregate the service cost component from the other components of net benefit cost. In connection with the adoption of ASU No. 2017‑07, the Company retroactively reclassified certain pension costs from other operating expenses to other income (expense), net. The adoption of ASU No. 2017-07 had no impact on the Company's condensed consolidated balance sheet.

Acquisition of ATS

As discussed in Note 1, the Company completed the ATS Acquisition in the first quarter of 2018. ATS was previously owned by Altice N.V. and a member of ATS's management through a holding company. As the acquisition is a combination of businesses under common control, the Company combined the results of operations and related assets and liabilities of ATS for all periods since the formation of ATS, including goodwill of $23,101, representing the amount previously transferred to ATS.

The following table summarizes the impact of adopting ASC 606 and the impact of the ATS Acquisition on the Company's condensed consolidated balance sheet:

Revenue from Contract with Customer [Abstract]

REVENUE AND CONTRACT ASSETS

REVENUE AND CONTRACT ASSETS

Revenue Recognition

Residential Services

The Company derives revenue through monthly charges to residential customers of its pay television, broadband, 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 pay TV" revenues. The Company recognizes pay television, broadband, and telephony revenues as the services are provided to a customer on a monthly basis. 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 three and six months ended June 30, 2018 the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $63,362 and $127,192, respectively. For the three and six months ended June 30, 2017 the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $64,804 and $129,790, respectively.

Business and Wholesale Services

The Company derives revenue from the sale of products and services to both large enterprise and SMB customers, including broadband, telephony, networking, and pay television 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 Wi-Fi, 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 and enable 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 also on a monthly basis. Contracts with large enterprise customers typically range from three to five years. Installation revenue related to our large enterprise customers is deferred and recognized over the average contract term. Installation revenue related to SMB customers is deferred and recognized over the benefit period, which is less than a year. The estimated benefit period for SMB customers takes into account both quantitative and qualitative factors including the significance of average installation fees to total recurring revenue per customer.

Advertising

As part of the agreements under which the Company acquires pay television 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. Advertising revenues are recognized when commercials are aired. 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. 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.

The Company's advanced advertising businesses provide data-driven, audience-based advertising solutions using advanced analytics tools that provide granular measurement of consumer groups, accurate hyper-local ratings and other insights into target audience behavior not available through traditional sample-based measurement services. Revenue earned from the Company's advanced advertising businesses are recognized when services are provided.

Other

Revenues derived from other sources are recognized when services are provided or events occur.

Contract Assets

Incremental costs incurred in obtaining a contract with a customer are deferred and recorded as a contract asset if the period of benefit is expected to be greater than one year. Sales commissions for enterprise and certain SMB customers are deferred and amortized over the average contract term. For sales commission expenses related to residential and SMB customers with a term of one year or less, the Company is utilizing the practical expedient and is recognizing the costs when incurred.  Cost of fulfilling a contract with a customer are deferred and recorded as a contract 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.

The following table provides information about contracts assets and contract liabilities related to contracts with customers:

	June 30, 2018		December 31, 2017, as adjusted
Contract assets (a)	$	24,358	$	24,329
Deferred revenue (b)	138,165		117,679

(a) Contract assets include primarily sales commissions for enterprise customers that are deferred and amortized over the average contract term.

(b) Deferred revenue represents payments received from customers for services that have yet to be provided and installation revenue which is deferred and recognized over the benefit period. The majority of the Company's deferred revenue represents payments for services for up to one month in advance from residential and SMB customers which is realized within the following month as services are performed.

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 to five years, and services may only be terminated in accordance with the contractual terms.

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 condensed 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 condensed 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 condensed 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 were 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 June 30, 2018, 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 June 30, 2018.

Interest Rate Swap Contracts

In May 2018, the Company entered into two interest rate swap contracts whereby one contract converts the interest rate on $2,970,000 of the CSC Holdings Term Loan Facility from a one-month LIBO rate to a three-month LIBO rate minus 0.226% and the second contract converts the interest rate on $1,496,250 of the CSC Holdings Incremental Term Loan from a one-month LIBO rate to a three-month LIBO rate minus 0.226%. The objective of these swaps is to potentially pay a lower interest rate than what the Company can elect under the terms of the CSC Holdings credit facilities agreement.

In April 2018, the Company entered into an interest rate swap contract which converts the interest rate on $1,255,513 of the Cequel Term Loan B from a one-month LIBO rate to a three-month LIBO rate minus 0.225%. The objective of this swap is to potentially pay a lower interest rate than what the Company can elect under the terms of the Cequel credit facilities agreement.

In June 2016, the Company entered into two fixed to floating interest rate swap contracts. One fixed to floating interest rate swap is converting $750,000 from a fixed rate of 1.6655% to a six-month LIBO rate and a second tranche of $750,000 from a fixed rate of 1.68% to a six-month LIBO rate. The objective of these swaps is to adjust the proportion of total debt that is subject to fixed and variable interest rates.

These swap contracts were not designated as hedges for accounting purposes. Accordingly, the changes in the fair value of these interest rate swap contracts are recorded through the statements of operations.

The Company does not hold or issue 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 condensed consolidated balance sheets:

		Asset Derivatives				Liability Derivatives
Derivatives Not Designated as Hedging Instruments	Balance Sheet Location	Fair Value at June 30, 2018		Fair Value at December 31, 2017		Fair Value at June 30, 2018			Fair Value at December 31, 2017

		$	110,999	$	52,545	$	(133,093	)	$	(239,951	)

Gains from the Company's derivative contracts related to the Comcast common stock for the three and six months ended June 30, 2018 of $42,159 and $210,511, respectively, are reflected in gain (loss) on derivative contracts, net in the Company's condensed consolidated statement of operations.

For the three and six months ended June 30, 2018 , the Company recorded a loss on investments of $58,420 and $310,996, respectively, primarily representing the net decrease in the fair values of the investment securities pledged as collateral. 

For the three and six months ended June 30, 2018, the Company recorded a loss on interest rate swap contracts of $12,929 and $44,851, respectively.

Settlements of Collateralized Indebtedness

The following table summarizes the settlement of the Company's collateralized indebtedness relating to Comcast shares that were settled by delivering cash equal to the collateralized loan value, net of the value of the related equity derivative contracts during the six months ended June 30, 2018: 

Number of shares (a)	10,802,118
Collateralized indebtedness settled	$	(337,148	)
Derivatives contracts settled	24
	(337,124		)
Proceeds from new monetization contracts	337,124
Net cash proceeds	$	—

The cash to settle the collateralized indebtedness was obtained from the proceeds of new monetization contracts covering an equivalent number of Comcast shares.  The terms of the new contracts allow the Company to retain upside participation in Comcast shares up to each respective contract's upside appreciation limit with downside exposure limited to the respective hedge price.

FAIR VALUE MEASUREMENT

Jun. 30, 2018

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 for each of these hierarchy levels, the Company's financial assets and financial liabilities that are measured at fair value on a recurring basis:

	Fair Value Hierarchy	June 30, 2018		December 31, 2017
Assets:
Money market funds	Level I	$	218,940	$	5,949
Investment securities pledged as collateral	Level I	1,409,361		1,720,357
Prepaid forward contracts	Level II	110,630		52,545
Interest rate swap contracts	Level II	369		—
Liabilities:
Prepaid forward contracts	Level II	9,623		162,049
Interest rate swap contracts	Level II	123,470		77,902
Contingent consideration related to 2017 acquisitions	Level III	2,233		32,233

The Company's cash equivalents, investment securities 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 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 June 30, 2018 related to the acquisition in the fourth quarter of 2017 amounted to approximately $2,233. The estimated amount recorded as of June 30, 2018 is approximately 51% of the contractual amount. The fair value of the consideration was estimated based on a probability assessment of attaining the targets as of June 30, 2018.

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 and Debentures, Senior Secured Notes, Senior Guaranteed Notes, and Notes Payable

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 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 condensed consolidated balance sheets, are summarized as follows:

		June 30, 2018				December 31, 2017
	Fair Value Hierarchy	Carrying Amount (a)		Estimated Fair Value		Carrying Amount (a)		Estimated Fair Value
CSC Holdings debt instruments:
Credit facility debt	Level II	$	4,435,479	$	4,470,000	$	3,393,306	$	3,435,000
Collateralized indebtedness	Level II	1,392,648		1,338,105		1,349,474		1,305,932
Senior guaranteed notes	Level II	3,283,795		3,195,375		2,291,185		2,420,000
Senior notes and debentures	Level II	6,107,472		6,727,849		6,409,889		7,221,846

Cablevision senior notes:
Senior notes and debentures	Level II	1,072,340		1,165,034		1,818,115		1,931,239
Cequel debt instruments:

Senior secured notes	Level II	2,572,438		2,535,500		2,570,506		2,658,930
Senior notes	Level II	2,804,435		2,942,800		2,770,737		2,983,615

		$	22,985,277	$	23,699,331	$	21,919,331	$	23,279,472

(a) Amounts are net of unamortized deferred financing costs, premiums and discounts.

The fair value estimates related to the Company's debt instruments presented above are made at a specific point in time, based on relevant market information and information about the financial instrument.  These estimates are subjective in nature and involve uncertainties and matters of significant judgments and therefore cannot be determined with precision.  Changes in assumptions could significantly affect the estimates.

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.

The Company recorded income tax benefit of $5,590 and $66,293 for the three and six months ended June 30, 2018, reflecting an effective tax rate of approximately 5% and 23%, respectively. The tax benefit was calculated based upon the actual effective tax rate for the year-to-date period. The Company determined this to represent the best estimate of the annual effective tax rate in light of the magnitude of the expected income and the significant permanent differences.

The Company recorded income tax benefit of $252,487 and $298,395 for the three and six months ended June 30, 2017, reflecting the AETR of approximately 34% and 35%, respectively.

As of June 30, 2018, the Company's federal net operating losses (“NOLs”) were approximately $2,274,000. The utilization of certain pre-merger NOLs of Cablevision and Cequel are limited pursuant to Internal Revenue Code Section 382. The Company does not expect such limitations to impact the ability to utilize the NOLs prior to their expiration.

SHARE BASED COMPENSATION

SHARE BASED COMPENSATION

Certain employees of the Company and its affiliates received awards of units in a carry unit plan of Neptune Management LP, an entity which has an ownership interest in the Company. The awards generally vest as follows: 50% on the second anniversary of June 21, 2016 for Cablevision employees or December 21, 2015 for Cequel employees ("Base Date"), 25% on the third anniversary of the Base Date, and 25% on the fourth anniversary of the Base Date.  Neptune Holding US GP LLC, the general partner of Neptune Management LP, has the right to repurchase (or to assign to an affiliate, including the Company, the right to repurchase) vested awards held by employees for sixty days following their termination.  For performance-based awards under the plan, vesting occurs upon achievement or satisfaction of a specified performance condition. The Company considered the probability of achieving the established performance targets in determining the share-based compensation with respect to these awards at the end of each reporting period.

Beginning on the fourth anniversary of the Base Date, the holders of carry units have an annual opportunity (a sixty day period determined by the administrator of the plan) to sell their units back to Neptune Holding US GP LLC (or affiliate, including the Company, designated by Neptune Holding US GP LLC). Accordingly, the carry units are presented as temporary equity on the consolidated balance sheets at fair value. Adjustments to fair value at each reporting period are recorded in paid-in capital.

The right of Neptune Holding US GP LLC to assign to an affiliate, including the Company, the right to repurchase an employee’s vested units during the sixty-day period following termination, or to satisfy its obligation to repurchase an employee’s vested units during annual60day periods following the fourth anniversary of the Base Date, may be exercised by Neptune Holding US GP LLC in its discretion at the time a repurchase right or obligation arises. The carry unit plan requires the purchase price payable to the employee or former employee, as the case may be, to be paid in cash, a promissory note (with a term of not more than3 yearsand bearing interest at the long-term applicable federal rate under Section 1274(d) of the Internal Revenue Code) or combination thereof, in each case as determined by Neptune Holding US GP LLC in its discretion at the time of the repurchase. Neptune Holding US GP LLC expects that vested units will be redeemed for shares of the Company's Class A common stock upon vesting.

The following table summarizes activity relating to carry units:

Legal Matters

Following expiration of the affiliation agreements for carriage of certain Fox broadcast stations and cable networks on October 16, 2010, News Corporation terminated delivery of the programming feeds to Cablevision, and as a result, those stations and networks were unavailable on Cablevision's cable television systems. On October 30, 2010, Cablevision and Fox reached an agreement on new affiliation agreements for these stations and networks, and carriage was restored. Several purported class action lawsuits alleging breach of contract, unjust enrichment, and consumer fraud and seeking unspecified compensatory damages, punitive damages and attorneys' fees were subsequently filed on behalf of Cablevision's customers seeking recovery for the lack of Fox programming. Those lawsuits were consolidated in an action before the U. S. District Court for the Eastern District of New York, and a consolidated complaint was filed in that court on February 22, 2011. On March 28, 2012, in ruling on Cablevision's motion to dismiss, the Court dismissed all of plaintiffs’ claims, except for breach of contract.  On March 30, 2014, the Court granted plaintiffs’ motion for class certification. The parties have entered into a settlement agreement, which was granted final approval by the Court on May 17, 2018. As of December 31, 2017, the Company had an estimated liability associated with a potential settlement totaling $6,000. The amount ultimately paid in connection with the proposed settlement could exceed the amount recorded.

In October 2015, the New York Attorney General began an investigation into whether the major Internet Service Providers in New York State deliver advertised Internet speeds. The Company is cooperating with this investigation and is currently in discussions with the New York Attorney General about resolving the investigation as to the Company, which resolution may involve operational and or financial components. While the Company is unable to predict the outcome of the investigation or these discussions, at this time it does not expect that the outcome will have a material adverse effect on its operations, financial conditions or cash flows.

The Company receives notices from third parties and, in some cases, is named as a defendant in certain lawsuits claiming infringement of various patents relating to various aspects of the Company's businesses.  In certain of these cases other industry participants are also defendants.  In certain of these cases the Company expects that any potential liability would be the responsibility of the Company's equipment vendors pursuant to applicable contractual indemnification provisions.  The Company believes that the claims are without merit, but is unable to predict the outcome of these matters or reasonably estimate a range of possible loss.

In addition to the matters discussed above, the Company is party to various lawsuits, some involving claims for substantial damages.  Although the outcome of these other matters cannot be predicted and the impact of the final resolution of these other 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 other lawsuits will have a material adverse effect on the financial position of the Company or the ability of the Company to meet its financial obligations as they become due.

Accounting Policies [Abstract]

Recently Adopted Accounting Pronouncements and Recently Issued But Not Yet Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In February 2018, the FASB issued ASU No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The primary provision of ASU No. 2018-02 allows for the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. ASU No. 2018-02 also requires certain disclosures about stranded tax effects. ASU No. 2018‑02 is effective for the Company on January 1, 2019, with early adoption permitted and will be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company elected to adopt ASU No. 2018-02 during the first quarter of 2018. The adoption resulted in the reclassification of stranded tax amounts of $2,163 associated with net unrecognized losses from the Company's pension plans from accumulated other comprehensive loss to retained earnings.

In May 2017, the FASB issued ASU No. 2017-09, Compensation- Stock Compensation (Topic 718). ASU No. 2017‑09 provides clarity and guidance on which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU No. 2017‑09 was adopted by the Company on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits (Topic 715). ASU No. 2017‑07 requires that an employer disaggregate the service cost component from the other components of net benefit cost. It also provides guidance on how to present the service cost component and the other components of net benefit cost in the income statement and what component of net benefit cost is eligible for capitalization. ASU No. 2017‑07 was adopted by the Company on January 1, 2018 and was applied retrospectively. As a result of the adoption, the Company reclassified the non-service cost components of the Company's pension expense for the three and six months ended March 31, 2017 from other operating expenses to other income (expense), net. The Company elected to apply the practical expedient which allowed it to reclassify amounts disclosed previously in the benefits plan note as the basis for applying retrospective presentation for comparative periods, as the Company determined it was impracticable to disaggregate the cost components for amounts capitalized and amortized in those periods. See Note 3 for information on the impact of the adoption of ASU No. 2017-07.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business, which amends Topic 805 to interpret the definition of a business by adding guidance to assist in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company adopted the new guidance on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities.  ASU No. 2016-01 modifies how entities measure certain equity investments and also modifies the recognition of changes in the fair value of financial liabilities measured under the fair value option. Entities will be required to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income. For financial liabilities measured using the fair value option, entities will be required to record changes in fair value caused by a change in instrument-specific credit risk (own credit risk) separately in other comprehensive income. ASU No. 2016-01 was adopted by the Company on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ("ASC 606"), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASC 606 replaced most existing revenue recognition guidance in GAAP and allowed the use of either the retrospective or cumulative effect transition method.

In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, in order to clarify the Codification and to correct any unintended application of the guidance. The amendments in this update affected the guidance in ASC 606. ASC 606 was adopted by the Company on January 1, 2018 on a full retrospective basis, which required the Company to reflect the impact of the updated guidance for all periods presented. The adoption of ASC 606 did not have a material impact on the Company’s financial position or results of operations. See Note 3 for information on the impact of the adoption of ASC 606.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. ASU No. 2016-15 also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The Company adopted the new guidance on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements.

Recently Issued But Not Yet Adopted Accounting Pronouncements

In January 2017, the FASB issued ASU No. 2017‑04, Intangibles-Goodwill and Other (Topic 350). ASU No. 2017‑04 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. ASU No. 2017‑04 becomes effective for the Company on January 1, 2020 with early adoption permitted and will be applied prospectively.

In February 2016, the FASB issued ASU No. 2016-02, Leases, which increases transparency and comparability by recognizing a lessee’s rights and obligations resulting from leases by recording them on the balance sheet as lease assets and lease liabilities. The new guidance becomes effective for the Company on January 1, 2019. Although, the Company has not yet completed the evaluation of the effect that ASU No. 2016-02 will have on its consolidated financial statements, upon adoption, the Company expects to recognize a right of use asset and liability related to substantially all operating lease arrangements on the Company's consolidated balance sheet.
