General Information
General Information	Note 1. General Information WideOpenWest, Inc. (“WOW” or the “Company”) was organized in Delaware in July 2012 as WideOpenWest Kite, Inc. WideOpenWest Kite, Inc. subsequently changed its name to WideOpenWest, Inc. in March 2017. On April 1, 2016, the Company consummated a restructuring (“Restructuring”) whereby WideOpenWest Finance, LLC (“WOW Finance”) became a wholly owned subsidiary of WOW. Previously, WOW Finance was owned by WOW, WideOpenWest Illinois, Inc., WideOpenWest Ohio, Inc. and Sigecom, Inc. (collectively, the “Members”, or WOW and “Affiliates”). Prior to the Restructuring, the Members were wholly owned subsidiaries of Racecar Acquisition, LLC (“Racecar Acquisition”). As a result of the Restructuring, the Affiliates merged with and into WOW, WOW became the sole subsidiary of Racecar Acquisition and WOW Finance became a wholly owned subsidiary of WOW. On May 25, 2017, the Company completed an initial public offering (“IPO”) of shares of its common stock, which are listed on the New York Stock Exchange (“NYSE”) under the ticker symbol “WOW”. Prior to its IPO, WOW was wholly owned by Racecar Acquisition, which is a wholly owned subsidiary of WideOpenWest Holdings, LLC (“Parent”). Subsequent to the IPO, Racecar Acquisition and former Parent do not own any shares in the Company as a result of a distribution of shares to their respective owners. In the following context, the terms we, us, WOW, or the Company may refer, as the context requires, to WOW or, collectively, WOW and its subsidiaries. The Company is a fully integrated provider of high-speed data (“HSD”), cable television (“Video”), and digital telephony (“Telephony”) services. The Company serves customers in nineteen Midwestern and Southeastern markets in the United States. The Company manages and operates its Midwestern broadband cable systems in Detroit and Lansing, Michigan; Chicago, Illinois; Cleveland and Columbus, Ohio; Evansville, Indiana and Baltimore, Maryland. The Southeastern systems are located in Augusta, Columbus, Newnan and West Point, Georgia; Charleston, South Carolina; Dothan, Auburn, Huntsville and Montgomery, Alabama; Knoxville, Tennessee; and Panama City and Pinellas County, Florida.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation Prior to the Restructuring, the Members were all under common control. The financial statements presented herein include the consolidated accounts of WOW and its subsidiaries and the combined accounts of its Affiliates. All significant intercompany accounts and transactions have been eliminated in consolidation and combination. As a result, the unaudited condensed 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. Because 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. The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and with the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, they do not include all of the information required by GAAP or Securities and Exchange Commission (“SEC”) rules and regulations for complete financial statements. The December 31, 2016 balance and results of operations for the nine months ended September 30, 2016 are presented on a combined condensed consolidated basis. The year-end combined condensed consolidated balance sheet was derived from audited financial statements. In the opinion of management, all normally recurring adjustments considered necessary for the fair presentation of the financial statements have been included, and the financial statements present fairly the financial position and results of operations for the interim periods presented. The results of operations for any interim period are not necessarily indicative of results expected for the full year or any future period. These unaudited condensed consolidated financial statements should be read in conjunction with the 2016 combined consolidated financial statements and notes thereto, together with the Company’s final prospectus filed with the SEC on May 25, 2017. Earnings or Loss per Share Basic earnings or loss per share attributable to the Company’s common shareholders is computed by dividing net earnings 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 units) 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 three months ended September 30, 2017 and 2016 and the nine months ended September 30, 2016 because the Company incurred a net loss in each of these periods 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 unaudited condensed consolidated financial statements. For the nine months ended September 30, 2017, the diluted earnings per share calculation resulted in an immaterial change in the weighted average number of common shares outstanding.

These accounting principles require management to make assumptions and estimates that affect the reported amounts and disclosures of assets and liabilities 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. To the extent there are differences between those estimates and actual results, the unaudited condensed consolidated financial statements may be materially affected. Recently Issued Accounting Standards 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 is currently evaluating the impact and timing of adopting this guidance. 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 substantially 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 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 and sales commission expense represents approximately 2% 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 intends to adopt 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 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.

Assets Held for Sale On August 1, 2017, the Company entered into a definitive agreement to sell a portion of its fiber network in the Company’s Chicago market to a subsidiary of Verizon for $225.0 million in cash. The Company anticipates the sale to be completed in the fourth quarter of 2017. In addition, at the closing of the definitive agreement, the Company and Verizon will enter into a new agreement pursuant to which the Company will complete the build-out of the network in exchange for approximately $50.0 million, which represented the estimated remaining build-out costs to complete the network at the time the definitive agreement was entered into. The $50.0 million will be payable as such network elements are completed. The Company anticipates such network would be completed in the second half of 2018. As a result of the definitive agreement, the Company concluded that as of September 30, 2017, the assets and liabilities associated with the fiber network met the criteria to be classified as held for sale. As of September 30, 2017, the Chicago fiber network has $149.2 million in total assets and $15.5 million in total liabilities held for sale that are included in the Company’s unaudited condensed consolidated balance sheets which includes approximately $7.0 million the Company has spent on construction subsequent to the signing of the definitive agreement on August 1, 2017.

Refinancing of the Term B Loans and Revolving Credit Facility On July 17, 2017, the Company entered into an eighth amendment (“Eighth Amendment”) to its Credit Agreement, with JPMorgan Chase Bank, N.A., as the administrative agent and revolver agent. Under the Eighth Amendment, (i) the Company borrowed new Term B loans in an aggregate principal amount of $230.5 million, for a total outstanding Term B loan principal amount of $2.28 billion and (ii) the revolving credit commitments were increased by an aggregate principal amount of $100.0 million, for a total outstanding revolving credit commitment of $300.0 million available to the Company under the revolving credit facility. The new Term B loans will mature on August 19, 2023 and bear interest, at the Company’s option, at a rate equal to ABR plus 2.25% or LIBOR plus 3.25%. Loans under the revolving credit facility will mature on May 31, 2022 and bear interest, at the Company’s option, at a rate equal to ABR plus 2.00% or LIBOR plus 3.00%. The guarantees, collateral and covenants in the Eighth Amendment remain unchanged from those contained in the credit agreement prior to the Eighth Amendment. The Company recorded a $6.3 million loss on early extinguishment of debt in the three months ended September 30, 2017 related to the write off of unamortized debt issuance costs and third party costs. As of September 30, 2017, the Company was in compliance with all debt covenants. On May 31, 2017, the Company entered into a seventh amendment (“Seventh Amendment”) to its Credit Agreement. The Seventh Amendment (i) refinanced the then-existing $200.0 million of borrowings available to the Company under the revolving credit facility and (ii) extended the maturity date of the revolving credit facility to May 31, 2022, unless an earlier date was triggered under certain circumstances. The interest rate margins applicable to the revolving credit facility bore interest at a rate equal to ABR plus 2.00% or LIBOR plus 3.00%. Additionally, the Company entered into an Incremental Commitment Letter to its revolving credit facility that increased the available borrowings to $300.0 million that became available upon compliance by the Company with certain conditions (see redemption of 10.25% senior notes whereby such conditionality was subsequently achieved as a result of the eighth amendment). The guarantees, collateral and covenants in the Seventh Amendment remained unchanged from those contained in the credit agreement prior to the Seventh Amendment. The Company recorded a $1.0 million loss on early extinguishment of debt in the three months ended June 30, 2017, primarily related to the write-off of deferred financing costs and third party costs. On August 19, 2016, the Company entered into a sixth amendment (“Sixth Amendment”) to its Credit Agreement. The Sixth Amendment provided for the addition of a $2.065 billion seven year Term B Loan which bore interest at LIBOR plus 3.50% or ABR plus 2.50% and included a 1.00% LIBOR floor. The Term B Loan had a maturity date of August 19, 2023, unless the earlier maturity dates set forth below was triggered under the following circumstances: the Term B Loan matured on April 15, 2019 if (i) any of the Company’s existing outstanding Senior Notes were outstanding on April 15, 2019, or (ii) any future indebtedness with a final maturity date prior to the date that is 91 days after August 19, 2023 was incurred to refinance the Company’s existing Senior Notes. The Term B Loan matured on July 15, 2019 if (i) any of the Company’s existing Senior Subordinated Notes were outstanding on July 15, 2019, or (ii) any indebtedness with a final maturity prior to the date that is 91 days after August 19, 2023 was incurred to refinance the Company’s existing Senior Subordinated Notes. As described below, the Senior Subordinated Notes were fully redeemed on December 18, 2016 and the Senior Notes were fully redeemed on July 17, 2017. Proceeds from the issuance of the Term B Loans pursuant to the Sixth Amendment were used to repay in full the existing $1.825 billion Term B Loan, which had a maturity date of April 15, 2019 and which bore interest at the same rates described above. The Company used the remaining $240.0 million in proceeds to fund the Company’s acquisition of HC Cable Opco, LLC (“NuLink”) and to redeem a portion of the Company’s 13.38% Senior Subordinated Notes. The Company recorded a loss on early extinguishment of debt of $32.1 million during the three months ended September 30, 2016. The loss primarily relates to the write off of the unamortized debt issuance costs and third part costs associated with the pre-existing Term B Loans. On May 11, 2016, the Company entered into a fifth amendment (“Fifth Amendment”) to its Credit Agreement. The Fifth Amendment provided for the addition of an incremental $432.5 million Term B Loan with a maturity date of April 2019 and which bore interest, at the Company’s option, at LIBOR plus 3.50% or ABR plus 2.50% and included a 1.00% LIBOR floor. Proceeds from the issuance of the Term B Loans were used to repay all remaining $382.5 million outstanding principal under the Company’s Term B-1 Loans which had a maturity date of July 2017 and which bore interest at LIBOR plus 3.00% or ABR plus 2.00% and included a 0.75% LIBOR floor. Partial Redemption of 10.25% Senior Notes On March 20, 2017, the Company utilized cash on hand to redeem $95.1 million in aggregate principal amount outstanding of the 10.25% Senior Notes. In addition to the partial redemption, the Company paid accrued interest on the 10.25% Senior Notes of $1.7 million and a call premium of $4.9 million. The Company recorded a loss on early extinguishment of debt of $5.0 million, primarily representing the cash call premium paid. Redemption of 10.25% Senior Notes On July 17, 2017, the Company used the proceeds of the new Term B loans under the Eighth Amendment, and borrowed $180.0 million under its revolving credit facility and cash on hand to fully redeem all of the Company’s remaining outstanding 10.25% Senior Notes due 2019 (the “Senior Notes”) and to pay certain fees and expenses. In connection with the redemption of the 10.25% Senior Notes, the Company satisfied and discharged the indenture governing the Senior Notes. The Company paid $729.9 million in principal amount, incurred prepayment fees of $18.7 million and paid accrued interest of $37.6 million. The Company recorded a loss on early extinguishment of debt of $19.8 million related to the write-off of deferred financing costs, premium, and prepayment fees. Retirement of 13.38% Senior Subordinated Notes During the year ended December 31, 2016, the Company made two redemption payments to early retire its 13.38% Senior Subordinated Notes. The final redemption payment was made on December 18, 2016.

Equity	Note 7. Equity Initial Public Offering On May 25, 2017, the Company completed an IPO of shares of its common stock, which are listed on the NYSE under the ticker symbol “WOW”. The Company sold 20,970,589 shares of its common stock at a price of $17 per share (including the exercise of the overallotment) for $356.5 million in gross proceeds. The Company incurred costs directly associated with the IPO of $21.8 million. Proceeds from the IPO (net of issuance costs) of $334.7 million are reflected in the Company’s unaudited condensed consolidated statement of stockholders’ deficit during the nine months ended September 30, 2017. Outstanding shares and per-share amounts disclosed as of September 30, 2017 and for all other comparative periods presented have been retroactively adjusted to reflect the effects of the May 25, 2017, 66,498.762 to 1 stock-split.

Stock-Based Compensation
Stock-Based Compensation	Note 8. Stock-Based Compensation 2017 Omnibus Incentive Plan In connection with the Company’s IPO, the Company’s Board of Directors adopted and approved the 2017 Omnibus Incentive Plan (“2017 Plan”) and cancelled its former management D units equity incentive plan (“2016 Profit Interest Plan”). The 2017 Plan provides for grants of stock options, restricted stock and performance awards. The Company’s directors, officers and other employees and persons who engage in services for the Company are eligible for grants under the 2017 Plan. The purpose of the 2017 Plan is to provide the individuals with incentives to maximize stockholder value and otherwise contribute to the Company’s success and to enable the Company to attract, retain and reward the best available persons for positions of responsibility. The 2017 Plan has authorized 6,355,054 shares of its common stock to be available for issuance under the 2017 Plan, subject to adjustment in the event of a reorganization, stock split, merger or similar change in the Company’s corporate structure or the outstanding shares of common stock. The Company’s Compensation Committee will administer the 2017 Plan. The Board of Directors also has the authority to administer the 2017 Plan and to take all actions that the Company’s Compensation Committee is otherwise authorized to take under the 2017 Plan. The terms and conditions of each award made under the 2017 Plan, including vesting requirements, will be set forth consistent with the 2017 Plan in a written agreement with the grantee. Employee Grants Senior management that had participated in the 2016 Profit Interest Plan were granted (based on a conversion factor of management units to new common shares) new restricted stock to replace the shares that were cancelled in the 2016 Profit Interest Plan. Under the 2017 Plan, 394,052 shares of restricted stock were granted that will vest ratably at 33% per year beginning on June 30, 2018 assuming the award recipient continues to be employed by the Company. Senior management also received 450,356 shares of restricted stock in connection with long-term incentive compensation under the 2017 Plan. These restricted stock grants will vest ratably at 33% per year beginning on June 30, 2018 assuming the award recipient continues to be employed by the Company. Employees that had participated in the 2016 Director Appreciation Rights Plan were granted new restricted stock (based on a conversion factor of the then calculated value of such pool). These employees were granted 78,050 shares of restricted stock under the 2017 Plan that will vest ratably at 33% per year beginning on June 30, 2018 assuming the award recipient continues to be employed by the Company. Each year, the Company’s Compensation Committee, in consultation with the Company’s Chief Executive Officer (“CEO”), establishes an annual incentive bonus plan. In 2017, the 2017 Management Bonus Plan (“2017 MBP”) was established, which provides incentive cash bonuses for the majority of the Company’s employees based upon the achievement of certain business and individual or department objectives, including most prominently adjusted consolidated earnings before interest, tax, depreciation and amortization. Bonus payouts were established based on a percentage of the participant’s base salary based on the title/position. In connection with the Company’s IPO, the Compensation Committee, in consultation with the Company’s CEO, granted restricted shares out of the 2017 Plan. The Compensation Committee granted restricted shares equal to 100% to 150% achievement of the 2017 MBP. Such grant in aggregate totaled 866,708 shares and will vest 100% on June 30, 2018 assuming the participant continues to be employed by the Company. Furthermore, the members of the Company’s Board of Directors received 54,361 shares, in aggregate, of restricted stock that will vest 100% beginning on June 30, 2018. The following table summarizes the restricted stock awards granted during the nine months ended September 30, 2017. Number of Outstanding January 1, 2017 — Granted Cancelled — Forfeited ) Outstanding September 30, 2017 The above table includes 472,102 of restricted shares that were granted from plans prior to the 2017 Plan, thus these restricted shares do not count towards the 6,355,054 shares authorized by the plan. These shares represented the unvested shares from the old 2016 Profit Interest Plan that will vest ratably at 33% per year beginning on June 30, 2018. For restricted stock awards that contain only service conditions for vesting, the Company calculates the award fair value based on the closing stock price on the accounting grant date. For the three months ended September 30, 2017 and 2016 the Company recorded $5.2 million and $0.4 million, respectively, of non-cash compensation expense which is reflected in selling, general and administrative expense and operating expenses (excluding depreciation and amortization), depending on the recipients’ duties, in the Company’s unaudited condensed consolidated statements of operations. During the nine months ended September 30, 2017 and 2016, the Company recorded $8.3 million and $0.5 million, respectively, of non-cash compensation expense which is reflected in selling, general and administrative expense and operating (excluding depreciation and amortization), depending on participants’ duties, in the Company’s unaudited condensed consolidated statements of operations.

Fair Value Measurements
Fair Value Measurements	Note 9. Fair Value Measurements The fair values of cash and cash equivalents, receivables, trade payables, short-term borrowings and the current portions of long-term debt approximate carrying values due to the short-term nature of these instruments. For assets and liabilities of a long-term nature, the Company determines fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. Market or observable inputs are the preferred source of values, followed by unobservable inputs or assumptions based on hypothetical transactions in the absence of market inputs. The Company applies the following hierarchy in determining fair value: · Level 1, defined as observable inputs being quoted prices in active markets for identical assets; · Level 2, defined as observable inputs other than quoted prices included in Level 1, including quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and · Level 3, defined as unobservable inputs for which little or no market data exists, consistent with reasonably available assumptions made by other participants therefore requiring assumptions based on the best information available. The estimated fair value of the Company’s long-term debt, which includes debt subject to the effects of interest rate risk, was based on dealer quotes considering current market rates and was approximately $2,457.2 million compared to carrying value of $2,460.0 million, not including debt issuance costs, discount and premium as of September 30, 2017. As the Company’s ratio of its aggregate debt balance has trended from quoted market prices in active markets to quoted prices in non-active markets, the Company has concluded that the fair value of debt should be classified as a Level 2.

Income Taxes

Income Taxes
Income Taxes	Note 10. 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 unaudited condensed consolidated financial statements in the period of enactment. The Company assesses the available positive and negative evidence to estimate whether sufficient taxable income will be generated to permit the utilization of existing deferred tax assets. On the basis of this evaluation, as of September 30, 2017, a valuation allowance of $128.0 million has been recorded to recognize only the portion of the deferred tax asset that is more likely than not to be realized. The valuation allowance is based on the Company’s existing positive and negative evidence. The amount of the deferred tax assets considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased based on the Company’s future operating results. The Company reported total income tax expense of $1.6 million and $2.7 million for the three months ended September 30, 2017 and 2016, respectively, and reported total income tax benefit of $16.4 million and $7.4 million for the nine months ended September 30, 2017 and 2016, respectively. On January 12, 2017, the Company and MidCo consummated an asset purchase agreement pursuant to which MidCo acquired the Company’s Lawrence, Kansas system for net proceeds of approximately $213.0 million in cash, subject to certain normal and customary purchase price adjustments set forth in the agreement. As a result of the sale, the Company has recorded $11.1 million of income tax expense. In addition, a deferred income tax benefit of $36.3 million was recognized as a result in the change of valuation allowance. The change in valuation allowance was due primarily to the utilization of NOLs from the disposal of indefinite lived assets related to the Lawrence, Kansas system sale transaction. The Company files income tax returns in the U.S. federal jurisdiction, and various state jurisdictions. For federal tax purposes, the Company’s 2013 through 2016 tax years remain open for examination by the tax authorities under the normal three year statute of limitations. Generally, for state tax purposes, the Company’s 2013 through 2016 tax years remain open for examination by the tax authorities under a three year statute of limitations. Should the Company utilize any of its U.S. or state loss carryforwards, their carryforward losses, which date back to 1995, would be subject to examination. As of September 30, 2017, the Company recorded gross unrecognized tax benefits of $31.2 million, all of which, if recognized, would affect the Company’s effective tax rate. Interest and penalties related to income tax liabilities, if incurred, are included in income tax benefit (expense) in the unaudited condensed consolidated statement of operations. The Company has accrued gross interest and penalties of $0.5 million. Management believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues are addressed in the Company’s tax audits in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. Unrecognized tax benefits consist primarily of tax positions related to issues associated with the Restructuring of WOW Finance and the acquisition of Knology, Inc. Depending on the resolution with certain state taxing authorities that is expected to occur within the next twelve months, there could be an adjustment to the Company’s unrecognized tax benefits and certain state tax matters. The Company is not currently under examination for U.S. federal income tax purposes, but does have various open tax controversy matters with various state taxing authorities.

Commitments and Contingencies	Note 11. Commitments and Contingencies The Company is party to various legal proceedings (including individual, class and putative class actions) arising in the normal course of its business covering a wide range of matters and types of claims including, but not limited to, general contracts, billing disputes, rights of access, programming, taxes, fees and surcharges, consumer protection, trademark and patent infringement, employment, regulatory, tort, claims of competitors and disputes with other carriers. In accordance with GAAP, WOW accrues an expense for pending litigation when it determines that an unfavorable outcome is probable and the amount of the loss can be reasonably estimated. Legal defense costs are expensed as incurred. None of the Company’s existing accruals for pending matters are material. WOW regularly monitors its pending litigation for the purpose of adjusting its accruals and revising its disclosures accordingly, in accordance with GAAP, when required. Litigation is, however, subject to uncertainty, and the outcome of any particular matter is not predictable. The Company vigorously defends its interests in pending litigation, and as of this date, WOW believes that the ultimate resolution of all such matters, after considering insurance coverage or other indemnities to which it is entitled, will not have a material adverse effect on its unaudited condensed consolidated financial position, results of operations, or cash flows.

Related Party Transactions	Note 12. Related Party Transactions Prior to the Company’s IPO, the Company paid a quarterly management fee of $0.4 million plus travel and miscellaneous expenses, if any, to Avista Capital Partners (“Avista”) and Crestview Advisors, LLC (“Crestview”), majority owners of the Company’s former Parent. In addition, pursuant to a consulting agreement dated as of December 18, 2015 by and among Parent, Avista and Crestview, Crestview is entitled to 50% of any management fee actually received by Avista. Such fee will no longer be paid in future periods. The management fee paid by the Company for the three months ended September 30, 2017 and 2016 amounted to nil and $0.4 million, respectively. The management fee paid by the Company for the nine months ended September 30, 2017 and 2016 amounted to $1.0 million and $1.3 million, respectively. On December 18, 2015, Crestview and the Company’s former Parent consummated a transaction whereby Crestview became the beneficial owner of approximately 35% of the Company’s former Parent. Under the terms of the agreement, Crestview’s funds purchased units held by Avista and other unit holders, and separately made a $125.0 million primary investment in newly-issued units. On April 29, 2016, funds managed by Avista and Crestview made an additional $40.0 million investment in newly-issued membership units in the Company’s former Parent. As of September 30, 2017, all the proceeds from the funds’ investments of Avista and Crestview in the amount of $143.3 million, net of transaction costs have been contributed to the Company. During the nine months ended September 30, 2017, the Company’s former Parent bought back vested Class A and Class B units from certain former employees of the Company. The former employees had the option to sell their units at a price set by the Company’s former Parent or decline such offer. The cash proceeds used to repurchase such units have been contributed down to the Company and reflected as such. The Company repurchased 415,494 of Class A units and 243,270 of Class B units for $8.8 million. As a result of the Company’s IPO, the Class A and Class B shares were converted to common shares of the Company. As of September 30, 2017 and December 31, 2016, the receivable balance from the former Parent and Members amounted to nil and $0.3 million, respectively.

Summary of Significant Accounting Policies
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation Prior to the Restructuring, the Members were all under common control. The financial statements presented herein include the consolidated accounts of WOW and its subsidiaries and the combined accounts of its Affiliates. All significant intercompany accounts and transactions have been eliminated in consolidation and combination. As a result, the unaudited condensed 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. Because 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. The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and with the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, they do not include all of the information required by GAAP or Securities and Exchange Commission (“SEC”) rules and regulations for complete financial statements. The December 31, 2016 balance and results of operations for the nine months ended September 30, 2016 are presented on a combined condensed consolidated basis. The year-end combined condensed consolidated balance sheet was derived from audited financial statements. In the opinion of management, all normally recurring adjustments considered necessary for the fair presentation of the financial statements have been included, and the financial statements present fairly the financial position and results of operations for the interim periods presented. The results of operations for any interim period are not necessarily indicative of results expected for the full year or any future period. These unaudited condensed consolidated financial statements should be read in conjunction with the 2016 combined consolidated financial statements and notes thereto, together with the Company’s final prospectus filed with the SEC on May 25, 2017.
Earnings or Loss per Share	Earnings or Loss per Share Basic earnings or loss per share attributable to the Company’s common shareholders is computed by dividing net earnings 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 units) 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 three months ended September 30, 2017 and 2016 and the nine months ended September 30, 2016 because the Company incurred a net loss in each of these periods 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 unaudited condensed consolidated financial statements. For the nine months ended September 30, 2017, the diluted earnings per share calculation resulted in an immaterial change in the weighted average number of common shares outstanding.

Use of Estimates	Use of Estimates The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP. These accounting principles require management to make assumptions and estimates that affect the reported amounts and disclosures of assets and liabilities 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. To the extent there are differences between those estimates and actual results, the unaudited condensed consolidated financial statements may be materially affected.
Recently Issued Accounting Standards and Recently Adopted Accounting Pronouncements	Recently Issued Accounting Standards 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 is currently evaluating the impact and timing of adopting this guidance. 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 substantially 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 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 and sales commission expense represents approximately 2% 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 intends to adopt 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 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.
