Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation Prior to the Restructuring, the Members were all under common control. For periods prior to Restructuring, the financial statements and notes to financial statements presented herein include the consolidated accounts of WOW and its subsidiaries and the combined accounts of its Affiliates and for periods subsequent to the Restructuring, the financial statements and notes to financial statements presented herein include the consolidated accounts of WOW and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation and combination. As a result, the combined consolidated financial statements of WOW reflect all transactions of the wholly owned subsidiaries of the former Parent and Racecar Acquisition. The Company operates as one operating segment. Certain employees of WOW participated in equity plans administered by the Company's former Parent. As the management units from the equity plan were issued from the former Parent's ownership structure, the management units' value directly correlated to the results of WOW, as the primary asset of the former Parent's investment in WOW. The management units for the equity plan have been "pushed down" to the Company, as the management units had been utilized as equity-based compensation for WOW management. Immediately prior to the Company's IPO, these management units were cancelled. Ownership Prior to the Company's IPO the former Parent's primary asset was its investment in WOW, the former Parent's ownership structure related to its ultimate ownership of WOW and consisting of various classes of common units that have been "pushed down" to the Company. Earnings or Loss per Share Basic earnings or loss per share attributable to the Company's common shareholders is computed by dividing net income or loss attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings or loss per share attributable to common shareholders presents the dilutive effect, if any, on a per share basis of potential common shares (such as restricted stock awards) as if they had been vested or converted during the periods presented. No such items were included in the computation of diluted loss per share for the year ended December 31, 2015 because the Company incurred a net loss in this period and the effect of inclusion would have been anti-dilutive. All of the shares outstanding and per share amounts have been retroactively adjusted to reflect the stock-split in the accompanying consolidated and combined consolidated financial statements.

These accounting principles require management to make assumptions and estimates that affect the reported amounts and disclosures of assets and liabilities, derivative financial instruments and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts and disclosures of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances. However, due to the inherent uncertainties in making estimates, actual results could differ from those estimates. Cash and Cash Equivalents Cash equivalents represent short-term investments consisting of money market funds that are carried at cost, which approximates fair value. The Company considers all short-term investments with an original maturity of three months or less at the date of purchase to be cash equivalents. Bad Debt Bad debt expense and the allowance for doubtful accounts are based on historical trends. The Company's policy to reserve for potential bad debts is based on the aging of the individual receivables. The Company manages credit risk by disconnecting services to customers who are delinquent, generally after sixty days of delinquency. The individual receivables are written-off after all reasonable efforts to collect the funds have been made. Actual write-offs may differ from the amounts reserved. The change in the allowance for doubtful accounts consists of the following for the years ended December 31, (in millions): 2017 2016 Balance at beginning of year $ $ Provision charged to expense Accounts written off ) ) Change in unreturned equipment reserves ) Other ​ ​ ​ ​ ​ ​ ​ ​ Balance at end of year $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Plant, Property and Equipment Plant, property and equipment are recorded at cost and include costs associated with the construction of cable transmission and distribution facilities and new service installations at the customer location. Capitalized costs include materials, labor, and certain indirect costs attributable to the capitalization activity. Maintenance and repairs are expensed as incurred. Upon sale or retirement of an asset, the cost and related depreciation are removed from the related accounts and resulting gains or losses are reflected in operating results. The Company makes judgments regarding the installation and construction activities to be capitalized. The Company capitalizes direct labor associated with capitalizable activities and indirect costs using standards developed from operational data, including the proportionate time to perform a new installation relative to the total installation activities and an evaluation of the nature of the indirect costs incurred to support capitalizable activities. Judgment is required to determine the extent to which indirect costs incurred related to capitalizable activities. Indirect costs include (i) employee benefits and payroll taxes associated with capitalized direct labor, (ii) direct variable costs of installation and construction vehicle costs, (iii) the direct variable costs of support personnel directly involved in assisting with installation activities, such as dispatchers and (iv) other indirect costs directly attributable to capitalizable activities. Plant, property and equipment are depreciated over the estimated useful life upon being placed into service. Depreciation of plant, property and equipment is provided on a straight-line method, over the following estimated useful lives: Asset Category Estimated Useful Office and technical equipment 3 - 10 Computer equipment and software 3 Customer premise equipment 5 Vehicles 5 Headend equipment 7 Distribution facilities 10 Building and leasehold improvements 5 - 20 Leasehold improvements are depreciated over the shorter of the estimated useful lives or lease terms. Intangible Assets and Goodwill Intangible assets consist primarily of acquired franchise operating rights, franchise related customer relationships and goodwill. Franchise operating rights represent the value attributable to agreements with local franchising authorities, which allow access to homes in the public right of way. The Company's franchise operating rights were acquired through business combinations. The Company does not amortize franchise operating rights as it has determined that they have an indefinite life. Costs incurred in negotiating and renewing franchise operating agreements are expensed as incurred. Franchise related customer relationships represent the value to the Company of the benefit of acquiring the existing cable subscriber base and are amortized over the estimated life of the subscriber base (four years) on a straight-line basis, which is shorter than the economic useful life, which approximates an accelerated method. Goodwill represents the excess purchase price over the fair value of the identifiable net assets acquired in business combinations. Asset Impairments Long-lived Assets The Company evaluates the recoverability of its long-lived assets whenever events or substantive changes in circumstances indicate that the carrying amount may not be recoverable. The evaluation is based on the undiscounted cash flows generated by the underlying asset groups, including estimated future operating results, trends or other determinants of fair value. If the total of the expected future undiscounted cash flows were less than the carrying amount of the asset group, the Company would recognize an impairment charge to the extent the carrying amount of the asset group exceeds its estimated fair value. The Company had no triggering events or impairment of its long-lived assets in any of the periods presented. Franchise Operating Rights The Company evaluates the recoverability of its franchise operating rights at least annually on October 1, or more frequently whenever events or substantive changes in circumstances indicate that the assets might be impaired. The Company evaluates the franchise operating rights for impairment by comparing the carrying value of the intangible asset to its estimated fair value utilizing both quantitative and qualitative methods. Any excess of the carrying value over the fair value would be expensed as an impairment loss. The Company calculates the fair value of franchise operating rights using the multi-period excess earnings method, an income approach, which calculates the value of an intangible asset by discounting its future cash flows. The fair value is determined based on estimated discrete discounted future cash flows attributable to each franchise operating right intangible asset using assumptions consistent with internal forecasts. Assumptions key in estimating fair value under this method include, but are not limited to, revenue and subscriber growth rates (less anticipated customer churn), operating expenditures, capital expenditures (including any build out), market share achieved, contributory asset charge rates, tax rates and discount rate. The discount rate used in the model represents a weighted average cost of capital and the perceived risk associated with an intangible asset such as franchise operating rights. See Note 7—Franchise Operating Rights & Goodwill for discussion of impairment charges recognized for the year ended December 31, 2017. Goodwill The Company assesses the recoverability of its goodwill at least annually on October 1, or more frequently whenever events or substantive changes in circumstances indicate that the asset might be impaired. The Company may first choose to assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. If the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the first and second steps of the goodwill impairment test are unnecessary. The Company may also choose to by-pass this assessment and proceed directly to the first step of the goodwill impairment test. In the first step of assessing goodwill for impairment, the Company assesses the recoverability for each reporting unit, which are represented by geographical operations of cable systems managed by the Company. The Company utilizes a discounted cash flow analysis to estimate the fair value of each reporting unit and compares such value to the carrying amount of the reporting unit. Any excess of the carrying value of goodwill over the estimated fair value of goodwill would be expensed as an impairment loss. Significant judgment by management is required to determine estimates and assumptions used in the valuation of plant, property and equipment, intangible assets and goodwill. See Note 7—Franchise Operating Rights & Goodwill for discussion of impairment charges recognized for the year ended December 31, 2017. Debt Issuance Costs Debt issuance costs incurred by the Company are capitalized and are amortized over the life of the related debt using the effective interest rate method and are included with long-term debt in the accompanying consolidated balance sheets. Other Noncurrent Assets Other noncurrent assets are comprised primarily of long-term prepaid software costs, prepaid franchise fees, and prepaid site leases. All prepaids are recognized as operating expenses and selling general and administrative expense over the period of usage. Fair Value of Financial Instruments Carrying amounts reported in the consolidated balance sheets for cash and cash equivalents are carried at fair value. The carrying amounts reported in the consolidated balance sheets for accounts receivable and accounts payable approximate fair value due to their short term maturities. The fair value of long-term debt is based on the debt's variable rate of interest and the Company's own credit risk and risk of nonperformance, as required by the authoritative guidance. Certain financial instruments potentially subject the Company to concentrations of credit risk. These financial instruments consist primarily of trade receivables and cash and cash equivalents. The Company places its cash and cash equivalents with high credit quality financial institutions. The Company does not enter into master netting arrangements. The Company periodically assesses the creditworthiness of the institutions with which it invests. The Company does, however, maintain invested balances in excess of federally insured limits. Programming Costs and Deferred Credits Programming is acquired for distribution to subscribers, generally pursuant to multi-year license agreements, with rates typically based on the number of subscribers that receive the programming. These programming costs are included in operating expenses in the month the programming is distributed. Deferred credits consist primarily of incentives received or receivable from cable networks for license of their programming. These incentive payments are deferred and recognized over the term of the related programming agreements as a reduction to programming costs in operating expenses. Asset Retirement Obligations The Company accounts for its asset retirement obligations in accordance with the authoritative guidance which requires an entity to recognize a liability for the fair value of a conditional asset retirement obligation when incurred if the fair value of the liability can be reasonably estimated. Certain of the Company's franchise agreements and leases contain provisions requiring the Company to restore facilities or remove equipment in the event that the franchise or lease agreement is not renewed. The Company expects to continually renew its franchise agreements. Accordingly, the possibility is remote that the Company would be required to incur significant restoration or removal costs related to these franchise agreements in the foreseeable future. An estimated liability, which could be significant, would be recorded in the unlikely event a franchise agreement containing such a provision were no longer expected to be renewed. An estimate of the obligations related to the removal provisions contained in the Company's lease agreements has been made and recorded in the consolidated and combined consolidated financial statements; however, the amount is not material. Revenue Recognition Charges for HSD, Video and Telephony services are billed in advance. Revenue for equipment rental, advertising, Video on Demand ("VOD") and pay-per-view programming is recognized as the service is provided based upon monthly service charges or fees per event in the period that the services are provided and are generally billed in arrears. Amounts billed in excess of recognized revenue are recorded as unearned service revenue. Installation revenue is recognized in the period the installation services are provided to the extent of direct selling costs. Any remaining amounts are deferred and recognized over the estimated average period that the subscribers are expected to remain connected to the cable system. The Company also leases to third parties some of its fiber network. Upfront fees for these lease agreements are recorded as unearned revenue and recognized as revenue over the term of the lease. Under the terms of the Company's non-exclusive franchise agreements, the Company is generally required to pay up to 5% of its gross revenues derived from providing video (but not HSD or telephony services) to the local franchise authority. The Company normally passes these fees through to its video subscribers. Franchise fees collected and paid are reported as revenues and operating expenses, respectively. Revenue from advertising sales is recognized when the commercial announcements are broadcast. The Company's trade receivables are subject to credit risk, as customer deposits are generally not required. The Company's credit risk is limited due to the large number of customers, individually small balances and short payment terms. The Company manages credit risk by screening applicants through the use of internal customer information, identification verification tools and credit bureau data. If a customer account is delinquent, various measures are used to collect amounts owed, including termination of the customer's service. Advertising Costs The cost of advertising is expensed as incurred and is included in selling, general and administrative expenses in the accompanying consolidated and combined consolidated statements of operations. Advertising expense during the years ended December 31, 2017, 2016 and 2015 was $23.3 million, $22.9 million and $20.4 million, respectively. Income Taxes The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax liabilities and assets are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the difference is expected to reverse. Additionally, the impact of changes in the tax rates and laws on deferred taxes, if any, is reflected in the financial statements in the period of enactment. As a result of the Restructuring, WOW Finance became a single member LLC for U.S. federal income tax purposes. The Restructuring is treated as a change in tax status related to WOW Finance, since a single member LLC is required to record current and deferred income tax taxes reflecting the results of its operations. From time to time, the Company engages in transactions in which the tax consequences may be subject to uncertainty. Examples of such transactions include business acquisitions and dispositions, including dispositions designed to be tax free, issues related to consideration paid or received, investments and certain financing transactions. Significant judgment is required in assessing and estimating the tax consequences of these transactions. The Company prepares and files tax returns based on interpretation of tax laws and regulations. In the normal course of business, the tax returns are subject to examination by various taxing authorities. Such examinations may result in future tax, interest and penalty assessments by these taxing authorities. In determining the Company's income tax provision for financial reporting purposes, the Company establishes a reserve for uncertain income tax positions unless such positions are determined to be more likely than not of being sustained upon examination, based on their technical merits. That is, for financial reporting purposes, the Company only recognizes tax benefits taken on the tax return that the Company believes are more likely than not of being sustained. There is considerable judgment involved in determining whether positions taken on the tax return are more likely than not of being sustained. The Company adjusts its tax reserve estimates periodically because of ongoing examinations by, and settlements with, the various taxing authorities, as well as changes in tax laws, regulations and interpretations. The consolidated income tax provision of any given year includes adjustments to prior year income tax accruals that are considered appropriate and any related estimated interest. The Company's policy is to recognize, when applicable, interest and penalties on uncertain income tax positions as part of income tax provision. Derivative Financial Instruments The Company has used derivative financial instruments to manage its exposure to fluctuations in interest rates by entering into interest rate exchange agreements such as interest rate swaps and interest rate caps. All derivatives, whether designated as a hedge or not, are required to be recorded on the consolidated balance sheet at fair value. If the derivative is not designated as a hedge, changes in the fair value of the derivative are recognized in earnings. None of the derivative instruments in effect during the period were designated as hedges for financial reporting purposes. No such derivative exists as of December 31, 2017. Share-based Compensation The Company's share-based compensation consists of awards of management incentive units, (prior to the Company's IPO) and restricted stock awards (subsequent to the Company's IPO). Compensation costs associated with these awards are based on the estimated fair value at the date of grant and are recognized over the period in which any related services are provided or when it is probable any related performance condition will be met and distributions are declared. The Company currently does not estimate forfeitures on the restricted stock awards but accounts for forfeitures as they occur. The Company recorded $13.4 million and $1.1 million of compensation expense during the years ended December 31, 2017 and 2016, respectively. Compensation expense was not significant for the year ended December 31, 2015. Segments The Company's chief operating decision maker ("CODM") regularly reviews the Company's results to assess the Company's performance and allocates resources at a consolidated level. Although the consolidated results include the Company's three products (i) HSD; (ii) Video; and (iii) Telephony and are used to assess performance by product(s), decisions to allocate resources (including capital) are made to benefit the consolidated Company. The three products are delivered through a unified network and have similar types or classes of customers. Furthermore, the decision to allocate resources to plant maintenance and to upgrade our service delivery over a unified network to the customer benefits all three product offerings and is not based on any given service product, management has determined that the Company has one reportable segment, broadband services. Recent Accounting Pronouncements In October 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory" ("ASU 2016-16"). ASU 2016-16 eliminates the current prohibition on the recognition of the income tax effects on the transfer of assets among subsidiaries. After adoption of this ASU, the income tax effects associated with these transfers, except for the transfer of inventory, will be recognized in the period the asset is transferred versus the current deferral and recognition upon either the sale of the asset to a third party or the remaining useful life of the asset. The standard will become effective for the Company beginning January 1, 2018, and will require any deferred taxes not yet recognized on intra-entity transfers to be recorded to retained earnings under a modified retrospective approach. The Company does not believe that the adoption of this pronouncement will have a material impact on its financial position, results of operations or cash flows. In August 2016, the FASB issued ASU No. 2016-15 to Topic 230 ("ASU 2016-15"), Statement of Cash Flows , making changes to the classification of certain cash receipts and cash payments in order to reduce diversity in presentation. This update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The update addresses eight specific cash flow issues, of which only one is applicable to the Company's financial statements. The Company does not believe that the adoption of this pronouncement will have a material impact on its financial position, results of operations or cash flows. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" ("ASU 2016-02"). Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company will adopt this guidance beginning with its first quarter ending March 31, 2019. The Company is in the process of evaluating the future impact of ASU 2016-02 on its financial position, results of operations and cash flows. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" ("ASU 2014-09"). ASU 2014-09 supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of the guidance in Accounting Standards Codification Topic 606 ("ASC 606") is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity is required to follow five steps which are comprised of (a) identifying the contract(s) with a customer; (b) identifying the performance obligations in the contract; (c) determining the transaction price; (d) allocating the transaction price to the performance obligations in the contract and (e) recognizing revenue when (or as) the entity satisfies a performance obligation. In August 2015, the FASB approved the deferral of the effective date of ASU 2014-09 by one year until January 1, 2018. The Company has completed its review of its revenue arrangements. Under current accounting policies, the Company recognizes upfront revenue related to installation activities to the extent of direct selling costs, which generally results in recognition of revenue when the installation related activities have been provided to the customer. Under the new revenue recognition standard, the Company's installation related activities will be recognized ratably over the period which the customer is expected to benefit from the initial installation fee. In addition, the Company will be required to capitalize direct costs associated with obtaining contracts with customers, primarily direct sales commissions, and will amortize the costs over a period consistent with the transfer of goods and services to the customer, including anticipated renewals. The Company's installation revenue represents less than 2% and direct sales commission expense represents approximately 3% of total revenue and expense, respectively, and any changes resulting from the adoption are not expected to have a material impact to the Company's financial position. The new standard also requires additional disclosures regarding the nature, timing and uncertainty of the Company's revenue arrangements. The Company adopted the guidance on January 1, 2018 using the cumulative effect transition method. In March 2016, the FASB issued ASU 2016-08, Principal Versus Agent Considerations (Reporting Revenue Gross Versus Net) ("ASU 2016-08"), which amends the principal-versus-agent implementation guidance and illustrations in ASC Topic 606. The FASB issued ASU 2016-08 in response to concerns identified by stakeholders, including those related to determining the appropriate unit of account under the revenue standard's principal-versus-agent guidance and applying the indicators of whether an entity is a principal or an agent in accordance with the revenue standard's control principle. ASU 2016-08 has the same effective date as ASU 2014-09 and requires adopting ASU 2016-08 by using the same transition method used to adopt ASU 2014-09. The Company does not believe adoption of the pronouncement will have a material impact on the Company's financial position, results of operations or cash flows. Recently Adopted Accounting Pronouncements In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2017-04 , Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , which eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under the amendments in the new ASU, goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The new standard is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis. Early adoption is permitted for annual or interim goodwill impairment testing performed after January 1, 2017. The Company early adopted this standard in the fourth quarter of 2017 in conjunction with its annual goodwill impairment assessment. See Note 7—Franchise Operating Rights & Goodwill for further discussion. In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09") which is intended to simplify certain aspects of the accounting for share-based payments to employees. The guidance in ASU 2016-09 requires all income tax effects of awards to be recognized in the statement of operations when the awards vest or are settled rather than recording excess tax benefits or deficiencies in additional paid-in capital. The guidance in ASU 2016-09 also allows an employer to repurchase more of an employee's shares than it could under prior guidance for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. For public companies, ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, and requires a modified retrospective approach to adoption. The adoption of this pronouncement did not have a material impact on the Company's financial position, results of operations or cash flows. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes ("ASU 2015-17"), which requires that all deferred tax liabilities and assets be classified as noncurrent amounts on the balance sheet. ASU 2015-17 became effective for interim and annual periods beginning after December 15, 2016. The Company early adopted this standard during the first quarter of 2016 and has applied prospective treatment. The adoption of this pronouncement did not have a material impact on the Company's financial position, results of operations or cash flows. |
