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. As of December 31, 2017, Altice USA is majority‑owned by Altice N.V., a public company with limited liability (naamloze vennootshcap) under Dutch law. Upon the completion of the Altice N.V. distribution discussed below, the Company will no longer be 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 and Cequel was contributed to Altice USA on June 9, 2016. Altice USA had no operations of its own other than the issuance of debt prior to the contribution of Cequel on June 9, 2016 by Altice N.V. The results of operations of Cequel for the year ended December 31, 2016 have been included in the results of operations of Altice USA for the same periods, as Cequel was under common control with Altice USA.
Altice USA acquired Cablevision Systems Corporation ("Cablevision" or "Optimum") on June 21, 2016 (see discussion below) and the results of operations of Cablevision are included with the results of operations of Cequel for the year ended December 31, 2017. The year ended December 31, 2016 operating results include the operating results of Cablevision from the date of acquisition, June 21, 2016.
The accompanying combined consolidated financial statements ("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 discussed below. All significant inter-company accounts and transactions have been eliminated in consolidation.
The accompanying consolidated financial statements also 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 20 for further details of the impact on the Company's historical financial statements.
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.
Acquisition of Altice Technical Services US Corp
ATS was formed to provide network construction and maintenance services and commercial and residential installations, disconnections, and maintenance. In the second quarter of 2017, the Company entered into an Independent Contractor Agreement with ATS that governs the terms of the services described above. The Company believes the services it receives from ATS will be of higher quality and at a lower cost than the Company could achieve without ATS, including for the construction of our new fiber-to-the home ("FTTH") network. The Company also entered into a Transition Services Agreement for the use of the Company's resources to provide various overhead functions to ATS, including accounting, legal and human resources and for the use of certain facilities, vehicles and technician tools during a transitional period that generally ended on December 31, 2017, although the term can be extended on a service-by-service basis. The Transition Services Agreement requires ATS to reimburse the Company for its cost to provide such services.
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 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 its formation. See Note 20 for the impact of the ATS Acquisition on the Company's consolidated balance sheet and statement of operations as of and for the year ended December 31, 2017. In connection with the ATS Acquisition, the Company recorded goodwill of $23,101, representing the amount previously transferred to ATS.

In addition, the carried interest plans of the stockholders were cashed out whereby payments were made to participants in such carried interest plans, including certain officers and directors of Cequel.
Altice N.V. Distribution
On January 8, 2018, Altice N.V. announced plans for the separation of the Company from Altice N.V. Altice N.V. will distribute 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”). Following the Distribution, Altice N.V. will no longer own a controlling equity interest in the Company, and the Company will operate independently from Altice N.V.
The implementation of the Distribution is expected to be subject to certain conditions precedent being satisfied or waived. Although Altice N.V. and the Company have not yet negotiated the final terms of the Distribution and related transactions, the Company expects that the following will be conditions to the Distribution:
Approval of Altice N.V. shareholders of (i) the distribution in kind and (ii) the board resolution approving the change in identity and character of the business of Altice N.V. resulting from the Distribution;
Receipt of certain U.S. regulatory approvals, which could take up to 180 days;
This Registration Statement filed on January 8, 2018 being declared effective by the U.S. Securities and Exchange Commission (the ‘‘Commission’’);
The entry into the Master Separation Agreement and the entry into, amendments to or termination of various arrangements between Altice N.V. and the Company, such as a license to use the Altice brand, the stockholders’ agreement among Altice USA, Altice N.V. and certain other parties and the management agreement pursuant to which the Company pays a quarterly management fee to Altice N.V.; and
The declaration and payment of a one-time $1.5 billion dividend to Altice USA stockholders as of a record date prior to the Distribution (the ‘‘Pre-Distribution Dividend’’).
Prior to Altice N.V.'s announcement of the Distribution, the Board of Directors of Altice USA, acting through its independent directors, approved in principle the payment of the Pre-Distribution Dividend to all shareholders immediately prior to completion of the separation. Formal approval of the Pre-Distribution Dividend and setting of a record date are expected to occur in the second quarter of 2018. The payment of the Pre-Distribution Dividend will be funded with available Cablevision revolving facility capacity and available cash from new financings, completed in January 2018, at CSC Holdings LLC, a wholly-owned subsidiary of Cablevision. In addition, the Board of Directors of Altice USA has authorized a share repurchase program of $2.0 billion, effective following completion of the separation.
In connection with the Distribution, it is expected that the Management Advisory and Consulting Services Agreement with Altice N.V. which provides certain consulting, advisory and other services will be terminated. Compensation under the terms of the agreement is an annual fee of $30,000 paid by the Company.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Summary of Significant Accounting Policies
Revenue Recognition
Residential Services
The Company derives revenue through monthly charges to residential customers of its 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 years ended December 31, 2017 and 2016, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $259,075 and $154,732, 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:

(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.
Multiple-Element Transactions
In the normal course of business, the Company may enter into multiple-element transactions where it is simultaneously both a customer and a vendor with the same counterparty or in which it purchases multiple products and/or services, or settles outstanding items contemporaneously with the purchase of a product or service, from a single counterparty. The Company's policy for accounting for each transaction negotiated contemporaneously is to record each deliverable of the transaction based on its best estimate of selling price in a manner consistent with that used to determine the price to sell each deliverable on a standalone basis.  In determining the fair value of the respective deliverable, the Company will utilize quoted market prices (as available), historical transactions or comparable transactions.
Technical and Operating Expenses
Costs of revenue related to sales of services are classified as "programming and other direct costs" in the accompanying consolidated statements of operations.
Programming Costs
Programming expenses related to the Company's pay television service represent fees paid to programming distributors to license the programming distributed to customers.  This programming is acquired generally under multi-year distribution agreements, with rates usually based on the number of customers that receive the programming.  If there are periods when an existing distribution agreement has expired and the parties have not finalized negotiations of either a renewal of that agreement or a new agreement for certain periods of time, the Company continues to carry and pay for these services until execution of definitive replacement agreements or renewals.  The amount of programming expense recorded during the interim period is based on the Company's estimates of the ultimate contractual agreement expected to be reached, which is based on several factors, including previous contractual rates, customary rate increases and the current status of negotiations.  Such estimates are adjusted as negotiations progress until new programming terms are finalized.
In addition, the Company has received, or may receive, incentives from programming distributors for carriage of the distributors' programming.  The Company generally recognizes these incentives as a reduction of programming costs in "programming and other direct costs", generally over the term of the distribution agreement.
Advertising Expenses
Advertising costs are charged to expense when incurred and are reflected in "other operating expenses" in the accompanying consolidated statements of operations.  Advertising costs amounted to $224,120 and $135,513 for the years ended December 31, 2017 and 2016, respectively.
Share-Based Compensation
Share-based compensation expense is based on the fair value of the portion of share-based payment awards that are ultimately expected to vest. Share-based compensation cost relates to awards of units in a carried unit plan and options.
For carried interest units, the Company measures share-based compensation cost at the grant date fair value and recognizes the expense over the requisite service period or when it is probable any related performance condition will be met. For carried interest units with graded vesting requirement, compensation cost is recognized on an accelerated method under the graded vesting method over the requisite service period for the carried interest unit. Carried interest units that vest entirely at the end of the vesting requirement are expensed on a straight-line basis.
The Company estimated the fair value of carried interest units using an option pricing model. Key inputs that were used in applying the option pricing method were total equity value, equity volatility, risk free rate and time to liquidity event. The estimate of total equity value was determined using a combination of the income approach, which incorporated cash flow projections that were discounted at an appropriate rate, and the market approach, which involved applying a market multiple to the Company’s projected operating results. The Company estimated volatility based on the historical equity volatility of comparable publicly-traded companies. Subsequent to the IPO, such subjective valuations and estimates were no longer necessary as the Company relied on the market price of the Company’s common stock to determine the fair value of share-based compensation awards. See Note 13 to the consolidated financial statements for additional information about our share-based compensation.
For stock option awards, the Company recognizes compensation expense based on the estimated grant date fair value using the Black-Scholes valuation model. For options not subject to performance based vesting conditions, the Company recognizes the compensation expense using a straight-line amortization method.
Income Taxes
The Company's provision for income taxes is based on current period income, changes in deferred tax assets and liabilities and changes in estimates with regard to uncertain tax positions.  Deferred tax assets are subject to an ongoing assessment of realizability.  The Company provides deferred taxes for the outside basis difference of its investment in partnerships. 
Cash and Cash Equivalents
The Company's cash investments are placed with money market funds and financial institutions that are investment grade as rated by Standard & Poor's and Moody's Investors Service.  The Company selects money market funds that predominantly invest in marketable, direct obligations issued or guaranteed by the United States government or its agencies, commercial paper, fully collateralized repurchase agreements, certificates of deposit, and time deposits.
The Company considers the balance of its investment in funds that substantially hold securities that mature within three months or less from the date the fund purchases these securities to be cash equivalents.  The carrying amount of cash and cash equivalents either approximates fair value due to the short-term maturity of these instruments or are at fair value.
Accounts Receivable
Accounts receivable are recorded at net realizable value. The Company periodically assesses the adequacy of valuation allowances for uncollectible accounts receivable by evaluating the collectability of outstanding receivables and general factors such as historical collection experience, length of time individual receivables are past due, and the economic and competitive environment.
Investments
Investment securities and investment securities pledged as collateral are classified as trading securities and are stated at fair value with realized and unrealized holding gains and losses included in net income.
Long-Lived Assets and Amortizable Intangible Assets
Property, plant and equipment, including construction materials, are carried at cost, and include all direct costs and certain indirect costs associated with the construction of cable systems, and the costs of new equipment installations.  Equipment under capital leases is recorded at the present value of the total minimum lease payments.  Depreciation on equipment is calculated on the straight-line basis over the estimated useful lives of the assets or, with respect to equipment under capital leases and leasehold improvements, amortized over the shorter of the lease term or the assets' useful lives and reported in depreciation and amortization (including impairments) in the consolidated statements of operations.
The Company capitalizes certain internal and external costs incurred to acquire or develop internal-use software.  Capitalized software costs are amortized over the estimated useful life of the software and reported in depreciation and amortization.
Customer relationships, trade names and other intangibles established in connection with acquisitions that are finite-lived are amortized in a manner that reflects the pattern in which the projected net cash inflows to the Company are expected to occur, such as the sum of the years' digits method, or when such pattern does not exist, using the straight-line basis over their respective estimated useful lives.
The Company reviews its long-lived assets (property, plant and equipment, and intangible assets subject to amortization that arose from acquisitions) for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable.  If the sum of the expected cash flows, undiscounted and without interest, is less than the carrying amount of the asset, an impairment loss is recognized as the amount by which the carrying amount of the asset exceeds its fair value.
Goodwill and Indefinite-Lived Intangible Assets
Goodwill and the value of franchises acquired in purchase business combinations which have indefinite useful lives are not amortized.  Rather, such assets are tested for impairment annually or upon the occurrence of a triggering event.
The Company assesses qualitative factors for its reporting units that carry goodwill.  If the qualitative assessment results in a conclusion that it is more likely than not that the fair value of a reporting unit exceeds the carrying value, then no further testing is performed for that reporting unit.
When the qualitative assessment is not used, or if the qualitative assessment is not conclusive and it is necessary to calculate the fair value of a reporting unit, then the impairment analysis for goodwill is performed at the reporting unit level using a two-step approach.  The first step of the goodwill impairment test is used to identify potential impairment by comparing the fair value of the reporting unit with its carrying amount, including goodwill utilizing an enterprise-value based premise approach.  If the carrying amount of the reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of goodwill impairment loss, if any.  The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill.  If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess.  The implied fair value of goodwill is determined in the same manner as the amount of goodwill which would be recognized in a business combination.
The Company assesses qualitative factors to determine whether it is necessary to perform the one-step quantitative identifiable indefinite-lived intangible assets impairment test.  This quantitative test is required only if the Company concludes that it is more likely than not that a unit of accounting’s fair value is less than its carrying amount.  When the qualitative assessment is not used, or if the qualitative assessment is not conclusive, the impairment test for other intangible assets not subject to amortization requires a comparison of the fair value of the intangible asset with its carrying value.  If the carrying value of the indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.
Deferred Financing Costs
Deferred financing costs are being amortized to interest expense using the effective interest method over the terms of the related debt.
Derivative Financial Instruments
The Company accounts for derivative financial instruments as either assets or liabilities measured at fair value.  The Company uses derivative instruments to manage its exposure to market risks from changes in certain equity prices and interest rates and does not hold or issue derivative instruments for speculative or trading purposes.  These derivative instruments are not designated as hedges, and changes in the fair values of these derivatives are recognized in the statements of operations as gains (losses) on derivative contracts. 
Commitments and Contingencies
Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when the Company believes it is probable that a liability has been incurred and the amount of the contingency can be reasonably estimated.
Recently Adopted Accounting Pronouncements
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 20 for information on the impact of the adoption of ASC 606.
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 years ended December 31, 2017 and 2016 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 (Note 17 of the consolidated financial statements) 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 20 for information on the impact of the adoption of ASU No. 2017-07.
In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which provides simplification of income tax accounting for share-based payment awards. The new guidance became effective for the Company on January 1, 2017. Amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements, forfeitures, and intrinsic value were applied using the modified retrospective transition method. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement and the practical expedient for estimating expected term were applied prospectively. The Company elected to apply the amendments related to the presentation of excess tax benefits on the statement of cash flows using the prospective transition method. In connection with the adoption on January 1, 2017, a deferred tax asset of approximately $310,771 for previously unrealized excess tax benefits was recognized with the offset recorded to accumulated deficit.
Recently Issued But Not Yet 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 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.
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 is effective for the Company on January 1, 2018 and will be applied prospectively.
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 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 new guidance is effective for the Company on January 1, 2018 and will be applied prospectively.
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 new guidance is effective for the Company on January 1, 2018 and will be applied retrospectively. The Company does not believe that the adoption of ASU No. 2016-15 will have a material effect on its consolidated statements of cash flows.
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. The Company has not yet completed the evaluation of the effect that ASU No. 2016-02 will have on its 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 is effective for the Company on January 1, 2018.  The Company does expect the adoption of ASU No. 2016-01 to have any effect on its consolidated financial statements.
Common Stock of Altice USA
At December 31, 2017, the Company had 246,982,292 shares of Class A common stock and 490,086,674 shares of Class B common stock, with a par value of $0.01, issued and outstanding. Each holder of Class A common stock has one vote per share while holders of Class B common stock have twenty-five votes per share. Class B shares can be converted to Class A common stock at anytime with a conversion ratio of one Class A common share for one Class B common share. 
At December 31, 2016, the Company had 100 shares of common stock, with a par value of $0.01, issued and outstanding.
Dividends and Distributions
The Company may pay dividends on its capital stock only from net profits and surplus as determined under Delaware law.  If dividends are paid on the Altice USA common stock, holders of the Altice USA Class A common stock and Altice USA Class B common stock are entitled to receive dividends, and other distributions in cash, stock or property, equally on a per share basis, except that stock dividends with respect to Altice USA Class A common stock may be paid only with shares of Altice USA Class A common stock and stock dividends with respect to Altice USA Class B common stock may be paid only with shares of Altice USA Class B common stock.
The Company's indentures restrict the amount of dividends and distributions in respect of any equity interest that can be made.
Prior to the Company's IPO, the Company declared and paid cash distributions to stockholders aggregating $839,700 in the second quarter of 2017. In 2016, the Company declared cash distributions of $445,176 of which $365,559 were paid in 2016 and $79,617 were paid in the first quarter of 2017.
Net Income (Loss) Per Share
Basic net income (loss) per common share attributable to Altice USA stockholders is computed by dividing net income (loss) attributable to Altice USA stockholders by the weighted average number of common shares outstanding during the period.  Diluted income per common share attributable to Altice USA stockholders reflects the dilutive effects of stock options. 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 income (loss) per share reflect the retroactive impact of the organizational transactions, discussed in Note 1, that occurred prior to the Company's IPO.
The following table presents a reconciliation of weighted average shares used in the calculation of the basic and diluted net income per share attributable to Altice USA stockholders for the year ended December 31, 2017:
Basic weighted average shares outstanding
696,055,000

Anti-dilutive shares totaling approximately 14,000 shares, have been excluded from diluted weighted average shares outstanding for the year ended December 31, 2017. 
Concentrations of Credit Risk
Financial instruments that may potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents and trade account receivables.  The Company monitors the financial institutions and money market funds where it invests its cash and cash equivalents with diversification among counterparties to mitigate exposure to any single financial institution.  The Company's emphasis is primarily on safety of principal and liquidity and secondarily on maximizing the yield on its investments.  Management believes that no significant concentration of credit risk exists with respect to its cash and cash equivalents because of its assessment of the creditworthiness and financial viability of the respective financial institutions.
The Company did not have a single customer that represented 10% or more of its consolidated revenues for the years ended December 31, 2017 and 2016, or 10% or more of its consolidated net trade receivables at December 31, 2017 and 2016, respectively.
Use of Estimates in Preparation of Financial Statements
The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  See Note 11 for a discussion of fair value estimates.
Reclassifications
Certain reclassifications have been made to the 2016 financial statements to conform to the 2017 presentation.

BUSINESS COMBINATIONS
ATS Acquisition
As the ATS acquisition discussed in Note 1 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 its formation. See Note 20 for the impact of the ATS Acquisition on the Company's consolidated balance sheet and statement of operations as of and for the year ended December 31, 2017.
Cablevision Acquisition
As discussed in Note 1, the Company completed the Cablevision Acquisition on June 21, 2016. The acquisition was accounted for as a business combination in accordance with ASC Topic 805. Accordingly, the Company recorded the fair value of the assets and liabilities assumed at the date of acquisition.
The following table provides the allocation of the total purchase price of $9,958,323 to the identifiable tangible and intangible assets and liabilities of Cablevision based on their respective fair values. The remaining useful lives represent the period over which acquired tangible and intangible assets with a finite life are being depreciated or amortized.

(a)
See Note 8 for additional information regarding a change in the remaining estimated useful lives of the Company's trade names.
The fair value of customer relationships and cable television franchises were valued using derivations of the "income" approach. The future expected earnings from these assets were discounted to their present value equivalent.
Trade names were valued using the relief from royalty method, which is based on the present value of the royalty payments avoided as a result of the company owning the intangible asset.
The basis for the valuation methods was the Company’s projections. These projections were based on management’s assumptions including among others, penetration rates for pay television, broadband, and telephony; revenue growth rates; operating margins; and capital expenditures. The assumptions are derived based on the Company’s and its peers’ historical operating performance adjusted for current and expected competitive and economic factors surrounding the cable industry. The discount rates used in the analysis are intended to reflect the risk inherent in the projected future cash flows generated by the respective intangible asset. The value is highly dependent on the achievement of the future financial results contemplated in the projections. The estimates and assumptions made in the valuation are inherently subject to significant uncertainties, many of which are beyond the Company's control, and there is no assurance that these results can be achieved. The primary assumptions for which there is a reasonable possibility of the occurrence of a variation that would have significantly affected the value include the assumptions regarding revenue growth, programming expense growth rates, the amount and timing of capital expenditures and the discount rate utilized.
In establishing fair value for the vast majority of the acquired property, plant and equipment, the cost approach was utilized. The cost approach considers the amount required to replace an asset by constructing or purchasing a new asset with similar utility, then adjusts the value in consideration of physical depreciation, and functional and economic obsolescence as of the appraisal date. The cost approach relies on management’s assumptions regarding current material and labor costs required to rebuild and repurchase significant components of property, plant and equipment along with assumptions regarding the age and estimated useful lives of property, plant and equipment.
The estimates of expected useful lives take into consideration the effects of contractual relationships, customer attrition, eventual development of new technologies and market competition.
Long-term debt assumed was valued using quoted market prices (Level 2). The carrying value of most other assets and liabilities approximated fair value as of the acquisition date.
As a result of applying business combination accounting, the Company recorded goodwill, which represented the excess of organization value over amounts assigned to the other identifiable tangible and intangible assets arising from expectations of future operational performance and cash generation.
The following table presents the unaudited pro forma revenue and net loss for the period presented as if the Cablevision Acquisition had occurred on January 1, 2016:
 
Year Ended December 31, 2016

9,154,816

The pro forma results presented above include the impact of additional amortization expense related to the identifiable intangible assets recorded in connection with the Cablevision Acquisition, additional depreciation expense related to the fair value adjustment to property, plant and equipment and the incremental interest resulting from the issuance of debt to fund the Cablevision Acquisition, net of the reversal of interest and amortization of deferred financing costs related to credit facilities that were repaid on the date of the Cablevision Acquisition and the accretion/amortization of fair value adjustments associated with the long-term debt acquired.
Other Acquisitions
In connection with certain acquisitions completed in the first and fourth quarters of 2017, the Company recorded amortizable intangibles of $45,000 relating to customer relationships and $9,400 relating to other amortizable intangibles. The Company recorded goodwill of $23,948, which represents the excess of the estimated purchase price of approximately $80,000 (based on current probability of contingent consideration) over the net book value of assets acquired. These values are based on preliminary fair value information currently available, which is subject to change within the measurement period (up to one year from the acquisition date). The acquired entities are included in the Cablevision segment.

PROPERTY, PLANT AND EQUIPMENT
PROPERTY, PLANT AND EQUIPMENT
Costs incurred in the construction of the Company's cable systems, including line extensions to, and upgrade of, the Company's hybrid fiber/coaxial infrastructure, initial placement of the feeder cable to connect a customer that had not been previously connected, and headend facilities are capitalized.  These costs consist of materials, subcontractor labor, direct consulting fees, and internal labor and related costs associated with the construction activities.  The internal costs that are capitalized consist of salaries and benefits of the Company's employees and the portion of facility costs, including rent, taxes, insurance and utilities, that supports the construction activities.  These costs are depreciated over the estimated life of the plant (10 to 25 years) and headend facilities (4 to 25 years).  Costs of operating the plant and the technical facilities, including repairs and maintenance, are expensed as incurred.
Installation costs associated with the initial deployment of new customer premise equipment (“CPE”) necessary to provide pay television, broadband or telephony services are also capitalized. These costs include materials, subcontractor labor, internal labor, and other related costs associated with the connection activities.  The departmental activities supporting the connection process are tracked through specific metrics, and the portion of departmental costs that is capitalized is determined through a time weighted activity allocation of costs incurred based on time studies used to estimate the average time spent on each activity.  These installation costs are amortized over the estimated useful lives of the CPE necessary to provide pay television, broadband or telephony services.  In circumstances where CPE tracking is not available, the Company estimates the amount of capitalized installation costs based on whether or not the business or residence had been previously connected to the network. These installation costs are depreciated over their estimated useful life of 3-5 years. The portion of departmental costs related to disconnecting services and removing CPE from a customer, costs related to connecting CPE that has been previously connected to the network and repair and maintenance are expensed as incurred.
The estimated useful lives assigned to our property, plant and equipment are reviewed on an annual basis or more frequently if circumstances warrant and such lives are revised to the extent necessary due to changing facts and circumstances.  Any changes in estimated useful lives are reflected prospectively.
Property, plant and equipment (including equipment under capital leases) consist of the following assets, which are depreciated or amortized on a straight-line basis over the estimated useful lives shown below:

OPERATING LEASES
The Company leases certain office, production, and transmission facilities, as well as office equipment, under terms of leases expiring at various dates through 2100.  The leases generally provide for escalating rentals over the term of the lease plus certain real estate taxes and other costs or credits.  Costs associated with such operating leases are recognized on a straight-line basis over the initial lease term.  The difference between rent expense and rent paid is recorded as deferred rent.  In addition, the Company rents space on utility poles for its operations.  The Company's pole rental agreements are for varying terms, and management anticipates renewals as they expire.  Rent expense, including pole rentals, for the years ended December 31, 2017 and 2016 amounted to $95,017 and $65,881, respectively.
The minimum future annual payments for all operating leases (with initial or remaining terms in excess of one year) during the next five years and thereafter, including pole rentals from January 1, 2018 through December 31, 2022, at rates now in force are as follows:

On May 23, 2017, Altice N.V. announced the adoption of a global brand to replace the Company's brands in the future, reducing the remaining useful lives of these trade name intangibles to three years from the date of the adoption, which reflected one year as an in-use asset and two years as a defensive asset. In December 2017, the Company made a decision to postpone the adoption of a global brand that would have replaced the Optimum brand, increasing the useful life of the Optimum trade name intangible asset to 5 years.
Amortization expense for the years ended December 31, 2017 and 2016 and aggregated $1,341,807 and $653,410, respectively.

CSC Holdings Credit Facilities
In connection with the Cablevision Acquisition, in October 2015, Finco, a wholly-owned subsidiary of the Company, which merged with and into CSC Holdings on June 21, 2016, entered into a senior secured credit facility, which provides U.S. dollar term loans currently in an aggregate principal amount of $3,000,000 ($2,985,000 outstanding at December 31, 2017) (the “CVC Term Loan Facility”, and the term loans extended under the CVC Term Loan Facility, the “CVC Term Loans”) and U.S. dollar revolving loan commitments in an aggregate principal amount of $2,300,000 (the “CVC Revolving Credit Facility” and, together with the Term Loan Facility, the “CVC Credit Facilities”), which are governed by a credit facilities agreement entered into by, inter alios, CSC Holdings, certain lenders party thereto and JPMorgan Chase Bank, N.A. as administrative agent and security agent (as amended, restated, supplemented or otherwise modified on June 20, 2016, June 21, 2016, July 21, 2016, September 9, 2016, December 9, 2016 and March 15, 2017, respectively, and as further amended, restated, supplemented or otherwise modified from time to time, the “CVC Credit Facilities Agreement”).
The amendment to the CVC Credit Facilities Agreement entered into on September 9, 2016, extended the maturity date of the CVC Term Loan Facility to October 11, 2024. In October 2016, CSC Holdings used the net proceeds from the sale of $1,310,000 aggregate principal amount of 5.5% senior guaranteed notes due 2027 (the ‘‘2027 Guaranteed Notes’’) (after the deduction of fees and expenses) to prepay outstanding loans under the CSC Holdings Term Credit Facility that were not extended pursuant to this amendment. In connection with the prepayment of the Term Credit Facility, the Company wrote-off the deferred financing costs and the unamortized discount related to the existing term loan aggregating $102,894. Additionally, the Company recorded deferred financing costs and an original issue discount of $7,249 and $6,250, respectively, which are both being amortized to interest expense over the term of the Term Loan Facility.
The amendment to the CVC Credit Facilities Agreement entered into on March 15, 2017 (“Extension Amendment”) increased the Term Loan by $500,000 to $3,000,000 and the maturity date for this facility was extended to July 17, 2025. The closing of the Extension Amendment occurred in April 2017 and the proceeds were used to refinance the entire $2,493,750 principal amount of existing Term Loans and redeem $500,000 of the 8.625% Senior Notes due September 2017 issued by Cablevision.

On June 21, 2016, in connection with the Cablevision Acquisition, the Company issued notes payable to affiliates and related parties aggregating $1,750,000, of which $875,000 bore interest at 10.75% and matured on December 20, 2023 and $875,000 bore interest at 11% and matured on December 20, 2024.
As discussed in Note 1, in connection with the Company's IPO, the Company converted the notes payable to affiliates and related parties (together with accrued and unpaid interest of $529 and applicable premium of $513,723) into shares of the Company’s common stock at the IPO price. The premium was recorded as a loss on extinguishment of debt on the Company's statement of operations for the year ended December 31, 2017. In connection with the conversion of the notes, the Company recorded a credit to paid in capital of $2,264,252.
For the year ended December 31, 2017 and 2016, the Company recognized interest expense of $90,405 and $102,557 related to these notes prior to their conversion.
Summary of Debt Maturities
The future maturities of debt payable by the Company under its various debt obligations outstanding as of December 31, 2017, including notes payable, collateralized indebtedness (see Note 10), and capital leases, are as follows:

DERIVATIVE CONTRACTS AND COLLATERALIZED INDEBTEDNESS
DERIVATIVE CONTRACTS AND COLLATERALIZED INDEBTEDNESS
Prepaid Forward Contracts
The Company has entered into various transactions to limit the exposure against equity price risk on its shares of Comcast Corporation ("Comcast") common stock.  The Company has monetized all of its stock holdings in Comcast through the execution of prepaid forward contracts, collateralized by an equivalent amount of the respective underlying stock.  At maturity, the contracts provide for the option to deliver cash or shares of Comcast stock with a value determined by reference to the applicable stock price at maturity.  These contracts, at maturity, are expected to offset declines in the fair value of these securities below the hedge price per share while allowing the Company to retain upside appreciation from the hedge price per share to the relevant cap price.  
The Company received cash proceeds upon execution of the prepaid forward contracts discussed above which has been reflected as collateralized indebtedness in the accompanying consolidated balance sheets.  In addition, the Company separately accounts for the equity derivative component of the prepaid forward contracts.  These equity derivatives have not been designated as hedges for accounting purposes.  Therefore, the net fair values of the equity derivatives have been reflected in the accompanying consolidated balance sheets as an asset or liability and the net increases or decreases in the fair value of the equity derivative component of the prepaid forward contracts are included in gain (loss) on derivative contracts in the accompanying consolidated statements of operations.
All of the Company's monetization transactions are obligations of its wholly-owned subsidiaries that are not part of CSC Holdings' 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 December 31, 2017, the Company did not have an early termination shortfall relating to any of these contracts.
The Company monitors the financial institutions that are counterparties to its equity derivative contracts.  All of the counterparties to such transactions carry investment grade credit ratings as of December 31, 2017.
Put/Call Options
In the third quarter of 2017, the Company entered into a put-call contract that expired in the third quarter of 2018 whereby the Company sold a put option and purchased a call option with the same strike price. These put-call options were settled as of December 31, 2017 and the Company recorded a loss of $97,410 for the year ended December 31, 2017, which represents the difference between the strike price and the closing price of the underlying shares.
Interest Rate Swap Contracts
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 six-month LIBO rate and a second tranche of $750,000 from a fixed rate of 1.68% to six-month LIBO rate. The objective of these swaps is to cover the exposure of the Cequel 2026 Senior Secured Notes issued by Cequel to changes in the market interest rate. 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.

Loss related to the Company's derivative contracts related to the Comcast common stock for the years ended December 31, 2017 and 2016 of $(138,920) and $(53,696), respectively, are reflected in gain (loss) on derivative contracts, net in the Company's consolidated statements of operations.
For the years ended December 31, 2017 and 2016, the Company recorded a gain on investments of $237,354 and $141,896, respectively, primarily representing the net increase in the fair values of the investment securities pledged as collateral. 
For the years ended December 31, 2017 and 2016, the Company recorded a gain (loss) on interest rate swap contracts of $5,482 and $(72,961), 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 year ended December 31, 2017

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. In connection with the execution of these contracts, the Company recorded (i) the fair value of the equity derivative contracts of $53,316 (in a net asset position), (ii) notes payable of $111,657, representing the fair value of the existing equity derivative contracts, in a liability position, and (iii) a discount on notes payable of $58,341.

FAIR VALUE MEASUREMENT

Fair Value Disclosures [Abstract]  
FAIR VALUE MEASUREMENT
FAIR VALUE MEASUREMENT
The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable.  Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity's pricing based upon their own market assumptions.  The fair value hierarchy consists of the following three levels:
Level I - Quoted prices for identical instruments in active markets.
Level II - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
Level III - Instruments whose significant value drivers are unobservable.
The following table presents for each of these hierarchy levels, the Company's financial assets and financial liabilities that are measured at fair value on a recurring basis:

Level III
 
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 related to acquisitions in the first and fourth quarters of 2017 of $30,000 and $2,233, respectively, was estimated based on a probability assessment of attaining the targets. The estimated amount recorded as of December 31, 2017 is the full contractual amount for the first quarter acquisition and approximately 51% of the contractual amount for the acquisition that occurred in the fourth quarter.
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, Notes Payable to Affiliates and Related Parties 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 consolidated balance sheets, are summarized as follows:

Pursuant to the enactment of the Tax Cuts & Jobs Act ("Tax Reform") on December 22, 2017, the Company recorded a noncash deferred tax benefit of $2,332,677 to remeasure the net deferred tax liability to adjust for the reduction in the corporate federal income tax rate 35% to 21% which is effective on January 1, 2018. This adjustment results primarily from a decrease in the deferred tax liabilities with regard to fixed assets and intangibles, partially offset by a decrease in the deferred tax asset for the federal net operating loss carry forward (‘‘NOL’’). The noncash deferred tax benefit is provisional. Revised estimates and additional guidance regarding application of Tax Reform may require adjustments during the allowable measurement period.
Overall, Tax Reform will have a favorable impact on the Company’s income tax profile. Additional first-year depreciation deductions represent a significant timing benefit. Since Tax Reform only limits the deduction for NOLs arising in years beginning after December 31, 2017, the timing of the Company’s deductions with regard to its existing NOLs is largely unaffected. The Company will be subject to Tax Reform’s limitation on interest deductibility which is based on a limit calculated without regard to depreciation or amortization through 2021. The resulting interest deduction that is deferred, and can be carried forward indefinitely, is expected to fully reverse. However, as is the case with any future deductible temporary difference, management will evaluate realizability to determine whether a valuation allowance is required. Management does not expect that a valuation allowance will be required based on its preliminary estimate of the current facts and circumstances. Repeal of the alternative minimum tax will reduce projected tax payments in the short term while also providing for the refund of alternative minimum tax credits.
As described in Note 1, in June, 2016, (i) Cequel was contributed to Altice USA and (ii) Altice USA completed the Cablevision Acquisition. Accordingly, in the second quarter of 2016, Cequel and Cablevision joined the federal consolidated and certain state combined income tax returns of Altice USA. As a result, the applicate tax rate used to measure deferred tax assets and liabilities of Cequel increased, resulting in a noncash deferred income tax charge of $153,660.
The tax effects of temporary differences which give rise to significant portions of deferred tax assets or liabilities and the corresponding valuation allowance are as follows.

On January 1, 2017, the Company adopted ASU No. 2016-09 using the prospective transition method with respect to the presentation of excess tax benefits in the statement of cash flows. In connection with the adoption, a deferred tax asset of $310,771 for previously unrealized excess tax benefits related to share-based payment awards was recognized with the offset recorded to accumulated deficit.
As of December 31, 2017, the Company's federal NOLs were approximately $2,676,000.  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.
As of December 31, 2017, the Company has $48,995 of alternative minimum tax credits which do not expire and $17,806 of research credits, expiring in varying amounts from 2023 through 2035.
Deferred tax assets have resulted primarily from the Company's future deductible temporary differences and NOLs. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax asset will not be realized. In evaluating the need for a valuation allowance, management takes into account various factors, including the expected level of future taxable income, available tax planning strategies and reversals of existing taxable temporary differences. If such estimates and related assumptions change in the future, the Company may be required to record additional valuation allowances against its deferred tax assets, resulting in additional income tax expense in the Company's consolidated statements of operations. Management evaluates the realizability of the deferred tax assets and the need for additional valuation allowances quarterly. Pursuant to the Cablevision Acquisition and Cequel Acquisition, deferred tax liabilities resulting from the book fair value adjustment increased significantly and future taxable income that will result from the reversal of existing taxable temporary differences for which deferred tax liabilities are recognized is sufficient to conclude it is more likely than not that the Company will realize all of its gross deferred tax assets, except those deferred tax assets against which a valuation allowance has been recorded which relate to certain state NOLs.
In the normal course of business, the Company engages in transactions in which the income tax consequences may be uncertain. The Company's income tax returns are filed based on interpretation of tax laws and regulations. Such income tax returns are subject to examination by taxing authorities. For financial statement purposes, the Company only recognizes tax positions that it believes are more likely than not of being sustained. There is considerable judgment involved in determining whether positions taken or expected to be taken on the tax return are more likely than not of being sustained.
A reconciliation of the beginning and ending amount of unrecognized tax benefits associated with uncertain tax positions, excluding associated deferred tax benefits and accrued interest, is as follows:
Balance at January 1, 2016
$
4,025

Increases related to prior year tax positions
11

Balance at December 31, 2017
$
4,036


As of December 31, 2017, if all uncertain tax positions were sustained at the amounts reported or expected to be reported in the Company's tax returns, the elimination of the Company's unrecognized tax benefits, net of the deferred tax impact, would decrease income tax expense by $5,585.
In the second quarter of 2016, the Company changed its accounting policy on a prospective basis to present interest expense relating to uncertain tax positions as additional interest expense. For the year ended December 31, 2017, $659 of interest expense relating to uncertain tax position was recorded to interest expense.
The most significant jurisdictions in which the Company is required to file income tax returns include the states of New York, New Jersey, Connecticut, the City of New York, Texas and West Virginia. The State of New York is presently auditing income tax returns for years 2009 through 2011. The State of New Jersey is presently auditing income tax returns for years 2013 through 2015.
Management does not believe that the resolution of the ongoing income tax examination described above will have a material adverse impact on the financial position of the Company.  Changes in the liabilities for uncertain tax positions will be recognized in the interim period in which the positions are effectively settled or there is a change in factual circumstances.

SHARE BASED COMPENSATION
SHARE BASED COMPENSATION
Carry Unit Plan
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. The carry unit plan has 259,442,785 units authorized for issuance, of which 211,670,834 have been issued to employees of the Company and 11,300,000 have been issued to employees of Altice N.V. and affiliated companies as of December 31, 2017.
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 annual 60 day 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 than 3 years and 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 Company measures the cost of employee services received in exchange for carry units based on the fair value of the award at grant date. In addition these units are presented as temporary equity on our consolidated balance sheet at fair value. For carry unit awards granted in 2016, an option pricing model was used which requires subjective assumptions for which changes in these assumptions could materially affect the fair value of the carry units outstanding. The time to liquidity event assumption was based on management’s judgment. The equity volatility assumption was estimated using the historical weekly volatility of publicly traded comparable companies. The risk-free rate assumed was based on the U.S. Constant Maturity Treasury Rates for a period matching the expected time to liquidity event. The discount for lack of marketability was based on Finnerty's (2012) average-strike put option model.
For carry unit awards granted in the first and second quarter of 2017, the Company estimated the grant date fair value based on the value established in the Company's IPO.
The following table summarizes activity relating to carry units:

The weighted average fair value per unit was $1.76 and $2.50 as of December 31, 2016 and December 31, 2017, respectively. For the years ended December 31, 2017 and 2016, the Company recognized an expense of $57,430 and $14,368, respectively, related to the push down of share-based compensation related to the carry unit plan of which approximately $55,258 and $9,849 related to units granted to employees of the Company and $2,172 and $4,519 related to employees of Altice N.V. and affiliated companies allocated to the Company.
Stock Option Plan
In connection with the Company's IPO, the Company adopted the Altice USA 2017 Long Term Incentive Plan (the "2017 LTIP"). Under the 2017 LTIP, the Company may grant awards of options, restricted shares, restricted share units, stock appreciation rights, performance stock, performance stock units and other awards. Under the 2017 LTIP, awards may be granted to officers, employees and consultants of the Company or any of its affiliates. The 2017 LTIP will be administered by the Company's Board of Directors (the "Board"), subject to the provision of the stockholders' agreement. The Board has delegated its authority to the Company's Compensation Committee. The Compensation Committee has the full power and authority to, among other things, select eligible participants, to grant awards in accordance with the 2017 LTIP, to determine the number of shares subject to each award or the cash amount payable in connection with an award and determine the terms and conditions of each award. The maximum aggregate number of shares that may be issued under the 2017 LTIP is 9,879,291. The Board has the authority to amend, suspend, or terminate the 2017 LTIP. No amendment, suspension or termination will be effective without the approval of the Company's stockholders if such approval is required under applicable laws, rules and regulations.
On December 30, 2017, the Company granted 5,110,747 nonqualified stock options under the 2017 LTIP. The stock options were granted with an exercise price of $19.48, equal to the 30 day volume weighted average of the closing price of Class A common stock as of the grant date. Certain nonqualified stock options (2,730,949 awards) will vest 100% on December 21, 2020 and 2,379,798 awards will vest 50% on the second anniversary, 25% on the third anniversary and 25% on the fourth anniversary of the date of grant, generally subject to continued employment with the Company or any of its affiliates, and expire ten years from the date of grant.
The Company calculated the fair value of each option award on the date of grant using the Black-Scholes valuation model.  The Company's computation of expected life was determined based on the simplified method (the average of the vesting period and option term) due to the Company's lack of recent historical data for similar awards.  The interest rate for periods within the contractual life of the stock option was based on interest yields for U.S. Treasury instruments in effect at the time of grant.  The Company's computation of expected volatility was based on historical volatility of its common stock and the expected volatility of comparable publicly-traded companies who granted options that had similar expected lives.
The following aggregate assumptions were used to calculate the fair values of stock option awards granted on December 30, 2017:

(a)
Purchase obligations primarily include contractual commitments with various programming vendors to provide video services to customers and minimum purchase obligations to purchase goods or services.  Future fees payable under contracts with programming vendors are based on numerous factors, including the number of customers receiving the programming.  Amounts reflected above related to programming agreements are based on the number of customers receiving the programming as of December 31, 2017 multiplied by the per customer rates or the stated annual fee, as applicable, contained in the executed agreements in effect as of December 31, 2017
(b)
Includes franchise and performance surety bonds primarily for the Company's cable television systems. 
(c)
Represent letters of credit guaranteeing performance to municipalities and public utilities and payment of insurance premiums. Payments due by period for these arrangements represent the year in which the commitment expires although payments under these arrangements are required only in the event of nonperformance.
The table above does not include obligations for payments required to be made under multi-year franchise agreements based on a percentage of revenues generated from video service per year.
Many of the Company's franchise agreements and utility pole leases require the Company to remove its cable wires and other equipment upon termination of the respective agreements.  The Company has concluded that the fair value of these asset retirement obligations cannot be reasonably estimated since the range of potential settlement dates is not determinable.
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. The Court granted preliminary approval of the settlement agreement on January 8, 2018, and set a hearing for final approval on May 17, 2018. As of December 31, 2016, the Company had an estimated liability associated with a potential settlement totaling $5,200. During the year ended December 31, 2017, the Company recorded an additional liability of $800. 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 and intends to defend the actions vigorously, 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.

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:

BENEFIT PLANS
Qualified and Non-qualified Defined Benefit Plans
Retirement Plans (collectively, the "Defined Benefit Plans")
The Company sponsors a non-contributory qualified defined benefit cash balance retirement plan (the "Pension Plan") for the benefit of non-union employees of Cablevision, as well as certain employees covered by a collective bargaining agreement in Brooklyn.
The Company maintains an unfunded non-contributory non-qualified defined benefit excess cash balance plan ("Excess Cash Balance Plan") covering certain current and former employees of Cablevision who participate in the Pension Plan. The Company also maintained an additional unfunded non-contributory, non-qualified defined benefit plan ("CSC Supplemental Benefit Plan") for the benefit of certain former officers and employees of Cablevision which provided that, upon retiring on or after normal retirement age, a participant receives a benefit equal to a specified percentage of the participant's average compensation, as defined.  All participants were 100% vested in the CSC Supplemental Benefit Plan.  The benefits related to the CSC Supplemental Plan were paid to participants in January 2017 and the plan was terminated.   
Cablevision's Pension Plan and the Excess Cash Balance Plan are frozen and no employee of Cablevision who was not already a participant could participate in the plans and no further annual Pay Credits (a certain percentage of employees' eligible pay) are made.  Existing account balances under the plans continue to be credited with monthly interest in accordance with the terms of the plans.

The discount rate of 3.53% for the period June 21, 2016 through December 31, 2016, represents the average of the quarterly discount rates used to remeasure the Company's projected benefit obligation and benefit costs in connection with the recognition of settlement losses discussed above.
The discount rate used by the Company in calculating the benefit costs for the Cash Balance Plan and the Excess Cash Balance Plan was determined based on the expected future benefit payments for the plans and from the Towers Watson U.S. Rate Link: 40-90 Discount Rate Model. The model was developed by examining the yields on selected highly rated corporate bonds.
The Company's expected long-term return on Pension Plan assets is based on a periodic review and modeling of the plan's asset allocation structure over a long-term horizon.  Expectations of returns and risk for each asset class are the most important of the assumptions used in the review and modeling and are based on comprehensive reviews of historical data, forward looking economic outlook, and economic/financial market theory.  The expected long-term rate of return was chosen as a best estimate and was determined by (a) historical real returns, net of inflation, for the asset classes covered by the investment policy, and (b) projections of inflation over the long-term period during which benefits are payable to plan participants.

The Pension Plan's investment objectives reflect an overall low risk tolerance to stock market volatility.  This strategy allows for the Pension Plan to invest in portfolios that would obtain a rate of return throughout economic cycles, commensurate with the investment risk and cash flow needs of the Pension Plan. The investments held in the Pension Plan are readily marketable and can be sold to fund benefit payment obligations of the plan as they become payable.
Investment allocation decisions are formally made by the Company's Benefit Committee, which takes into account investment advice provided by its external investment consultant.  The investment consultant takes into account expected long-term risk, return, correlation, and other prudent investment assumptions when recommending asset classes and investment managers to the Company's Benefit Committee. The major categories of the Pension Plan assets are cash equivalents and bonds which are marked-to-market on a daily basis.  Due to the Pension Plan's significant holdings in long-term government and non-government fixed income securities, the Pension Plan's assets are subjected to interest rate risk; specifically, a rising interest rate environment. Consequently, an increase in interest rates may cause a decrease to the overall liability of the Pension Plan thus creating a hedge against rising interest rates. In addition, a portion of the Pension Plan's bond portfolio is invested in foreign debt securities where there could be foreign currency risks associated with them, as well as in non-government securities which are subject to credit risk of the bond issuer defaulting on interest and/or principal payments.

The Company currently expects to contribute approximately $18,000 to the Pension Plan in 2018. 
Defined Contribution Plans 
The Company maintains the Cablevision 401(k) Savings Plan, a contributory qualified defined contribution plan for the benefit of non-union employees of Cablevision.  Participants can contribute a percentage of eligible annual compensation and the Company will make a matching cash contribution or discretionary contribution, as defined in the plan.  In addition, the Company maintains an unfunded non-qualified excess savings plan which was frozen on January 1, 2017 for which the Company provided a matching contribution similar to the Cablevision 401(k) Savings Plan.  Applicable employees of the Company were eligible for an enhanced employer matching contribution, as well as a year-end employer discretionary contribution to the Cablevision 401(k) Savings Plan and the Cablevision Excess Savings Plan.
Through September 30, 2017, the Company also maintained a 401(k) plan for employees of Cequel. Cequel employees that qualified for participation were able to contribute a percentage of eligible annual compensation and the Company would make a matching cash contribution, as defined in the plan. During the fourth quarter of 2017, the Suddenlink 401(k) plan assets were transferred to the Cablevision 401(k) Savings Plan and the plan was renamed the Altice USA 401(k) Savings Plan.
The cost associated with these plans (including the enhanced employer matching and discretionary contributions on 2016) was $27,577 and $28,501 for the years ended December 31, 2017 and 2016, respectively.

CHANGE IN ACCOUNTING POLICIES AND ATS ACQUISITION (Notes)

Dec. 31, 2017
Accounting Changes and Error Corrections [Abstract]  
CHANGE IN ACCOUNTING POLICIES AND ATS ACQUISITION
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, Revenue from Contracts with Customers. 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 amortization 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 periods prior to January 1, 2018, costs 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.
Acquisition of Altice Technical Services US Corp
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 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 its formation, including goodwill of $23,101, representing the amount previously transferred to ATS.
The adoption of ASU No. 2017-07 had no impact on the Company's consolidated balance sheet. The following table summarizes the impact of adopting ASC 606 and the impact of the ATS Acquisition on the Company's consolidated balance sheets:

Subsequent Events [Abstract]  
Subsequent Event
SUBSEQUENT EVENT
In January 2018, CSC Holdings borrowed $150,000 under its revolving credit facility and entered into a new $1,500,000 incremental term loan facility (the "Incremental Term Loan") under its existing CVC Credit Facilities Agreement. The Incremental Term Loan was priced at 99.5% and will mature on January 25, 2026. The Incremental Term Loan is comprised of eurodollar borrowings or alternate base rate borrowings, and bears interest at a rate per annum equal to the adjusted LIBO rate or the alternate base rate, as applicable, plus the applicable margin, where the applicable margin is (i) with respect to any alternate base rate loan, 1.50% per annum and (ii) with respect to any eurodollar loan, 2.50% per annum.
In January 2018, CSC Holdings issued $1,000,000 aggregate principal amount of 5.375% senior guaranteed notes due February 1, 2028 (the "2028 Guaranteed Notes"). The 2028 Guaranteed Notes are senior unsecured obligations and rank pari passu in right of payment with all of the existing and future senior indebtedness, including the existing senior notes and the CVC Credit Facilities and rank senior in right of payment to all of existing and future subordinated indebtedness.
The proceeds from the 2028 Guaranteed Notes, together with proceeds from the Incremental Term Loan, borrowings under the CVC revolving credit facility and cash on hand, were used in February 2018 to repay certain senior notes ($300,000 principal amount of CSC Holdings' senior notes due in February 2018 and $750,000 principal amount of Cablevision senior notes due in April 2018) and will be used to fund a dividend of $1,500,000 to the Company's stockholders immediately prior to and in connection with the Distribution discussed in Note 1.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
12 Months Ended
Dec. 31, 2017
Accounting Policies [Abstract]  
Revenue Recognition
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 years ended December 31, 2017 and 2016, the amount of franchise fees and certain other taxes and fees included as a component of revenue aggregated $259,075 and $154,732, 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:

103,996

 
(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.
Multiple Element Transactions
Multiple-Element Transactions
In the normal course of business, the Company may enter into multiple-element transactions where it is simultaneously both a customer and a vendor with the same counterparty or in which it purchases multiple products and/or services, or settles outstanding items contemporaneously with the purchase of a product or service, from a single counterparty. The Company's policy for accounting for each transaction negotiated contemporaneously is to record each deliverable of the transaction based on its best estimate of selling price in a manner consistent with that used to determine the price to sell each deliverable on a standalone basis.  In determining the fair value of the respective deliverable, the Company will utilize quoted market prices (as available), historical transactions or comparable transactions.
Programming Costs
Technical and Operating Expenses
Costs of revenue related to sales of services are classified as "programming and other direct costs" in the accompanying consolidated statements of operations.
Programming Costs
Programming expenses related to the Company's pay television service represent fees paid to programming distributors to license the programming distributed to customers.  This programming is acquired generally under multi-year distribution agreements, with rates usually based on the number of customers that receive the programming.  If there are periods when an existing distribution agreement has expired and the parties have not finalized negotiations of either a renewal of that agreement or a new agreement for certain periods of time, the Company continues to carry and pay for these services until execution of definitive replacement agreements or renewals.  The amount of programming expense recorded during the interim period is based on the Company's estimates of the ultimate contractual agreement expected to be reached, which is based on several factors, including previous contractual rates, customary rate increases and the current status of negotiations.  Such estimates are adjusted as negotiations progress until new programming terms are finalized.
In addition, the Company has received, or may receive, incentives from programming distributors for carriage of the distributors' programming.  The Company generally recognizes these incentives as a reduction of programming costs in "programming and other direct costs", generally over the term of the distribution agreement.
Advertising Expenses
Advertising Expenses
Advertising costs are charged to expense when incurred and are reflected in "other operating expenses" in the accompanying consolidated statements of operations.
Share-based Compensation
Share-Based Compensation
Share-based compensation expense is based on the fair value of the portion of share-based payment awards that are ultimately expected to vest. Share-based compensation cost relates to awards of units in a carried unit plan and options.
For carried interest units, the Company measures share-based compensation cost at the grant date fair value and recognizes the expense over the requisite service period or when it is probable any related performance condition will be met. For carried interest units with graded vesting requirement, compensation cost is recognized on an accelerated method under the graded vesting method over the requisite service period for the carried interest unit. Carried interest units that vest entirely at the end of the vesting requirement are expensed on a straight-line basis.
The Company estimated the fair value of carried interest units using an option pricing model. Key inputs that were used in applying the option pricing method were total equity value, equity volatility, risk free rate and time to liquidity event. The estimate of total equity value was determined using a combination of the income approach, which incorporated cash flow projections that were discounted at an appropriate rate, and the market approach, which involved applying a market multiple to the Company’s projected operating results. The Company estimated volatility based on the historical equity volatility of comparable publicly-traded companies. Subsequent to the IPO, such subjective valuations and estimates were no longer necessary as the Company relied on the market price of the Company’s common stock to determine the fair value of share-based compensation awards. See Note 13 to the consolidated financial statements for additional information about our share-based compensation.
For stock option awards, the Company recognizes compensation expense based on the estimated grant date fair value using the Black-Scholes valuation model. For options not subject to performance based vesting conditions, the Company recognizes the compensation expense using a straight-line amortization method.
Income Taxes
Income Taxes
The Company's provision for income taxes is based on current period income, changes in deferred tax assets and liabilities and changes in estimates with regard to uncertain tax positions.  Deferred tax assets are subject to an ongoing assessment of realizability.  The Company provides deferred taxes for the outside basis difference of its investment in partnerships.
Cash and Cash Equivalents
Cash and Cash Equivalents
The Company's cash investments are placed with money market funds and financial institutions that are investment grade as rated by Standard & Poor's and Moody's Investors Service.  The Company selects money market funds that predominantly invest in marketable, direct obligations issued or guaranteed by the United States government or its agencies, commercial paper, fully collateralized repurchase agreements, certificates of deposit, and time deposits.
The Company considers the balance of its investment in funds that substantially hold securities that mature within three months or less from the date the fund purchases these securities to be cash equivalents.  The carrying amount of cash and cash equivalents either approximates fair value due to the short-term maturity of these instruments or are at fair value.
Accounts Receivable
Accounts Receivable
Accounts receivable are recorded at net realizable value. The Company periodically assesses the adequacy of valuation allowances for uncollectible accounts receivable by evaluating the collectability of outstanding receivables and general factors such as historical collection experience, length of time individual receivables are past due, and the economic and competitive environment.
Investments
Investments
Investment securities and investment securities pledged as collateral are classified as trading securities and are stated at fair value with realized and unrealized holding gains and losses included in net income.
Long-Lived Assets and Amortizable Intangible Assets - Property, Plant, and Equipment
The Company reviews its long-lived assets (property, plant and equipment, and intangible assets subject to amortization that arose from acquisitions) for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable.  If the sum of the expected cash flows, undiscounted and without interest, is less than the carrying amount of the asset, an impairment loss is recognized as the amount by which the carrying amount of the asset exceeds its fair value
Long-Lived Assets and Amortizable Intangible Assets
Property, plant and equipment, including construction materials, are carried at cost, and include all direct costs and certain indirect costs associated with the construction of cable systems, and the costs of new equipment installations.  Equipment under capital leases is recorded at the present value of the total minimum lease payments.  Depreciation on equipment is calculated on the straight-line basis over the estimated useful lives of the assets or, with respect to equipment under capital leases and leasehold improvements, amortized over the shorter of the lease term or the assets' useful lives and reported in depreciation and amortization (including impairments) in the consolidated statements of operations.
The Company capitalizes certain internal and external costs incurred to acquire or develop internal-use software.  Capitalized software costs are amortized over the estimated useful life of the software and reported in depreciation and amortization.
Amortizable Intangible Assets
Customer relationships, trade names and other intangibles established in connection with acquisitions that are finite-lived are amortized in a manner that reflects the pattern in which the projected net cash inflows to the Company are expected to occur, such as the sum of the years' digits method, or when such pattern does not exist, using the straight-line basis over their respective estimated useful lives.
The Company reviews its long-lived assets (property, plant and equipment, and intangible assets subject to amortization that arose from acquisitions) for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable.  If the sum of the expected cash flows, undiscounted and without interest, is less than the carrying amount of the asset, an impairment loss is recognized as the amount by which the carrying amount of the asset exceeds its fair value.
Goodwill and Indefinite-Lived Intangible Assets
Goodwill and Indefinite-Lived Intangible Assets
Goodwill and the value of franchises acquired in purchase business combinations which have indefinite useful lives are not amortized.  Rather, such assets are tested for impairment annually or upon the occurrence of a triggering event.
The Company assesses qualitative factors for its reporting units that carry goodwill.  If the qualitative assessment results in a conclusion that it is more likely than not that the fair value of a reporting unit exceeds the carrying value, then no further testing is performed for that reporting unit.
When the qualitative assessment is not used, or if the qualitative assessment is not conclusive and it is necessary to calculate the fair value of a reporting unit, then the impairment analysis for goodwill is performed at the reporting unit level using a two-step approach.  The first step of the goodwill impairment test is used to identify potential impairment by comparing the fair value of the reporting unit with its carrying amount, including goodwill utilizing an enterprise-value based premise approach.  If the carrying amount of the reporting unit exceeds its fair value, the second step of the goodwill impairment test is performed to measure the amount of goodwill impairment loss, if any.  The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill.  If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess.  The implied fair value of goodwill is determined in the same manner as the amount of goodwill which would be recognized in a business combination.
The Company assesses qualitative factors to determine whether it is necessary to perform the one-step quantitative identifiable indefinite-lived intangible assets impairment test.  This quantitative test is required only if the Company concludes that it is more likely than not that a unit of accounting’s fair value is less than its carrying amount.  When the qualitative assessment is not used, or if the qualitative assessment is not conclusive, the impairment test for other intangible assets not subject to amortization requires a comparison of the fair value of the intangible asset with its carrying value.  If the carrying value of the indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.
Deferred Financing Costs
Deferred Financing Costs
Deferred financing costs are being amortized to interest expense using the effective interest method over the terms of the related debt.
Derivative Financial Instruments
Derivative Financial Instruments
The Company accounts for derivative financial instruments as either assets or liabilities measured at fair value.  The Company uses derivative instruments to manage its exposure to market risks from changes in certain equity prices and interest rates and does not hold or issue derivative instruments for speculative or trading purposes.  These derivative instruments are not designated as hedges, and changes in the fair values of these derivatives are recognized in the statements of operations as gains (losses) on derivative contracts. 
Commitments and Contingencies
Commitments and Contingencies
Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when the Company believes it is probable that a liability has been incurred and the amount of the contingency can be reasonably estimated.
Recently Adopted Accounting Pronouncements and Recently Issued But Not Yet Adopted Accounting Pronouncements
Recently Adopted Accounting Pronouncements
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 20 for information on the impact of the adoption of ASC 606.
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 years ended December 31, 2017 and 2016 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 (Note 17 of the consolidated financial statements) 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 20 for information on the impact of the adoption of ASU No. 2017-07.
In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-09, Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which provides simplification of income tax accounting for share-based payment awards. The new guidance became effective for the Company on January 1, 2017. Amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements, forfeitures, and intrinsic value were applied using the modified retrospective transition method. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement and the practical expedient for estimating expected term were applied prospectively. The Company elected to apply the amendments related to the presentation of excess tax benefits on the statement of cash flows using the prospective transition method. In connection with the adoption on January 1, 2017, a deferred tax asset of approximately $310,771 for previously unrealized excess tax benefits was recognized with the offset recorded to accumulated deficit.
Recently Issued But Not Yet 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 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.
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 is effective for the Company on January 1, 2018 and will be applied prospectively.
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 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 new guidance is effective for the Company on January 1, 2018 and will be applied prospectively.
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 new guidance is effective for the Company on January 1, 2018 and will be applied retrospectively. The Company does not believe that the adoption of ASU No. 2016-15 will have a material effect on its consolidated statements of cash flows.
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. The Company has not yet completed the evaluation of the effect that ASU No. 2016-02 will have on its 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 is effective for the Company on January 1, 2018.  The Company does expect the adoption of ASU No. 2016-01 to have any effect on its consolidated financial statements.

The Company may pay dividends on its capital stock only from net profits and surplus as determined under Delaware law.  If dividends are paid on the Altice USA common stock, holders of the Altice USA Class A common stock and Altice USA Class B common stock are entitled to receive dividends, and other distributions in cash, stock or property, equally on a per share basis, except that stock dividends with respect to Altice USA Class A common stock may be paid only with shares of Altice USA Class A common stock and stock dividends with respect to Altice USA Class B common stock may be paid only with shares of Altice USA Class B common stock.
The Company's indentures restrict the amount of dividends and distributions in respect of any equity interest that can be made.
Net Income (Loss) Per Share
Net Income (Loss) Per Share
Basic net income (loss) per common share attributable to Altice USA stockholders is computed by dividing net income (loss) attributable to Altice USA stockholders by the weighted average number of common shares outstanding during the period.  Diluted income per common share attributable to Altice USA stockholders reflects the dilutive effects of stock options. 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 income (loss) per share reflect the retroactive impact of the organizational transactions, discussed in Note 1, that occurred prior to the Company's IPO.
Concentrations of Credit Risk
Concentrations of Credit Risk
Financial instruments that may potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents and trade account receivables.  The Company monitors the financial institutions and money market funds where it invests its cash and cash equivalents with diversification among counterparties to mitigate exposure to any single financial institution.  The Company's emphasis is primarily on safety of principal and liquidity and secondarily on maximizing the yield on its investments.  Management believes that no significant concentration of credit risk exists with respect to its cash and cash equivalents because of its assessment of the creditworthiness and financial viability of the respective financial institutions.
Use of Estimates in Preparation of Financial Statements
Use of Estimates in Preparation of Financial Statements
The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.  See Note 11 for a discussion of fair value estimates.

On May 23, 2017, Altice N.V. announced the adoption of a global brand to replace the Company's brands in the future, reducing the remaining useful lives of these trade name intangibles to three years from the date of the adoption, which reflected one year as an in-use asset and two years as a defensive asset. In December 2017, the Company made a decision to postpone the adoption of a global brand that would have replaced the Optimum brand, increasing the useful life of the Optimum trade name intangible asset to 5 years.
