Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The accompanying 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. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission (“SEC”); however, in the opinion of management, the disclosures made are adequate to ensure the information presented is not misleading. The year-end 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 2020 Annual Report filed with the SEC on February 24, 2021. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in accordance with GAAP requires 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, including but not limited to the potential impacts arising from COVID-19. 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 ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ​ In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 provides optional guidance, expedients and exceptions for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this update apply to all entities, subject to meeting the criteria, which participate in contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. ASU 2020-04 was subsequently amended by ASU 2021-01, Reference Rate Reform (Topic 848), Scope, which refines the scope of Topic 848 and permits optional expendients and exceptions when accounting for derivative contracts and certain hedging relationships. The amendments of these updates are available to all entities as of March 12, 2020 through December 31, 2022. The Company has not yet adopted these amendments, but has determined the impact of adopting this guidance will not have a material impact on its financial position, results of operations and cash flows. ​ Recently Adopted Accounting Pronouncements ASU 2019-12, Income Taxes —Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted this guidance prospectively as of January 1, 2021. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows. ​ ​

Stock-Based Compensation
Stock-Based Compensation	Note 7. Stock-Based Compensation WOW’s 2017 Omnibus Incentive 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 Omnibus Incentive Plan. The 2017 Omnibus Incentive Plan has authorized 12,074,128 shares of common stock to be available for issuance, subject to adjustment in the event of a reorganization, stock split, merger or similar change in the Company’s corporate structure of the outstanding shares of common stock. The following table presents restricted stock activity during the three months ended March 31, 2021: ​ ​ ​ ​ ​ Number of ​ ​ Unvested ​ ​ Restricted Stock ​ ​ Shares Outstanding, beginning of period ​ 4,990,971 Granted ​ 767,689 Vested ​ (1,233,213) Forfeited ​ (101,562) Outstanding, end of period(1) ​ 4,423,885 (1) The total outstanding non-vested shares of restricted stock awards granted to employees and directors are included in total outstanding shares as of March 31, 2021. 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. Restricted stock generally vests ratably over a four year period based on the date of grant. Nonvested Performance Shares On March 3, 2021, the Company granted 209,621 performance shares which will vest based on the Company’s achievement level relative to the following performance measures at December 31, 2023: 50% based upon the Company’s Total Shareholder Return (“TSR”) relative to the TSRs of the Company’s peer group and 50% based on the Company’s three-year cumulative EBITDA metric. EBITDA is defined as net income (loss) before net interest expense, income taxes, depreciation and amortization (including impairments), impairment losses on intangibles and goodwill, management fees to related party, the write-off of any asset, loss on early extinguishment of debt, integration and restructuring expenses and all non-cash charges and expenses (including stock compensation expense) and certain other income and expenses. Upon achievement of the minimum threshold performance metric, the grantee may earn 50% to 200% of their respective target shares based on the performance goal. The performance shares based on relative TSR performance have a market condition and are valued using a Monte Carlo simulation model on the grant date, which resulted in a grant date fair value of $27.76 per share. The estimated fair value is amortized to expense over the requisite service period, which ends on December 31, 2023. The following assumptions were used in the Monte Carlo simulation for computing the grant date fair value of the performance shares with a market condition: risk-free interest rate of 0.26%, volatility factors in the expected market price of the Company's common shares of 59.77% and an expected life of three years. ​ The performance shares based on three-year cumulative EBITDA have a performance condition. The probability of achieving the performance condition is assessed at each reporting period. If it is deemed probable that the performance condition will be met, compensation cost will be recognized based on the closing price per share of the Company's common stock on the date of the grant multiplied by the number of awards expected to be earned. If it is deemed that it is not probable that the performance condition will be met, the Company will discontinue the recognition of compensation cost and any compensation cost previously recorded will be reversed. At March 31, 2021, achievement of the performance condition for the performance shares was deemed probable. ​ The Company recorded $3.1 million and $2.7 million for the three months ended March 31, 2021 and 2020, respectively, of non-cash stock-based compensation expense which is reflected in selling, general and administrative expense in the Company’s unaudited condensed consolidated statements of operations.

Earnings (Loss) per Common Share
Earnings (Loss) per Common Share	Note 8. Earnings per Common Share Basic earnings or loss per share attributable to the Company’s common stockholders is computed by dividing net income or loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings or loss per share attributable to common stockholders 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. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ ​ March 31, ​ 2021 2020 ​ ​ (in millions, except share data) Net income ​ $ 9.6 ​ $ 0.1 ​ ​ ​ ​ ​ ​ ​ Basic weighted-average shares ​ 82,031,043 ​ 81,037,633 Effect of dilutive securities: ​ ​ ​ ​ Restricted stock awards ​ 3,598,940 ​ 499,180 Diluted weighted-average shares ​ 85,629,983 ​ 81,536,813 ​ ​ ​ ​ ​ ​ ​ Basic earnings per share ​ $ 0.12 ​ $ 0.00 Diluted earnings per share ​ $ 0.11 ​ $ 0.00 ​ The dilutive effect of the potential common shares from the performance shares is included in diluted earnings per share upon the satisfaction of certain performance and market conditions. These conditions are evaluated at each reporting period and if the conditions have been satisfied during the reporting period, the number of contingently issuable shares are included in the computation of diluted earnings per share. As of March 31, 2021, the Company determined the performance conditions were not yet achieved; however, the market conditions indicated a certain level of achievement within the payout range. Therefore, the contingently issuable performance shares associated with the market condition were included in the computation of diluted earnings per share.

Fair Value Measurements
Fair Value Measurements	Note 9. Fair Value Measurements The fair values of cash and cash equivalents, receivables and trade payables approximate their 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 values determined using models that utilize significant unobservable inputs for which little or no market data exists, discounted cash flow methodologies or similar techniques, or other determinations requiring significant management judgment or estimation. ​ The Company’s derivative instrument is accounted for at fair value on a recurring basis and classified within Level 2 of the valuation hierarchy and was valued at $3.8 million and $9.4 million as of March 31, 2021 and December 31, 2020, respectively. The fair value of the derivative instrument is measured as the present value of all expected future cash flows based on the LIBOR-based swap yield curves as of March 31, 2021. The present value calculation uses discount rates that have been adjusted to reflect the credit quality of the Company and its counterparties. ​ The estimated fair value of the Company’s long-term debt is based on dealer quotes considering current market rates for the Company’s credit facility and is classified as Level 2. The inputs used to determine the fair value of the Company’s aggregate debt balance has trended from quoted market prices in active markets to quoted prices in non-active markets. The fair value of the Company’s long-term debt was valued at $2,200.2 million and $2,203.1 million as of March 31, 2021 and December 31, 2020, respectively. Long-term debt fair value does not include debt issuance costs and discounts. ​ There were no transfers into or out of Level 1, 2 or 3 during the periods ended March 31, 2021 and December 31, 2020. ​ The Company’s nonfinancial assets such as franchise operating rights, property, plant, and equipment, and other intangible assets are not measured at fair value on a recurring basis; however, they are subject to fair value adjustments in certain circumstances, such as when there is evidence that an impairment may exist. When such impairments are recorded, fair values are generally classified within Level 3 of the valuation hierarchy. ​

Derivative Instruments and Hedging Activities
Derivative Instruments and Hedging Activities	Note 10. Derivative Instruments and Hedging Activities The Company is exposed to certain risks during the normal course of its business arising from adverse changes in interest rates. The Company selectively uses derivative financial instruments (“derivatives”), including interest rate swaps, to manage interest rate risk. The Company does not hold or issue derivative instruments for speculative purposes. Fluctuations in interest rates can be volatile, and the Company’s risk management activities do not totally eliminate these risks. Consequently, these fluctuations could have a significant effect on the Company’s financial results. ​ The Company’s exposure to interest rate risk results primarily from its variable rate borrowings. On May 9, 2018, the Company entered into variable to fixed interest rate swap agreements for a notional amount of $1,361.2 million to hedge the outstanding principal balance of its variable rate term loan debt. ​ As of March 31, 2021, the Company is the fixed rate payor on two interest rate swap contracts that effectively fix the LIBOR-based index used to determine the interest rates charged on the Company’s total long-term debt of $2,259.2 million, not including unamortized debt issuance costs and discount. These contracts fix approximately 60% of the Company’s term loan variable rate exposure at 2.7% and have an expiration date of May 2021. These swap agreements qualify as hedging instruments and have been designated as cash flow hedges of forecasted LIBOR-based interest payments. As all of the critical terms of each of the derivative instruments matched the underlying terms of the hedged debt and related forecasted interest payments, these hedges were considered highly effective. Based on LIBOR-based swap yield curves as of March 31, 2021, the Company expects to reclassify losses of $3.8 million out of accumulated other comprehensive loss (“AOCL”) into earnings within the next 12 months. The following table summarizes the notional amounts and fair values of the Company’s outstanding derivatives by risk category and instrument type within the unaudited condensed consolidated balance sheet as of March 31, 2021 and December 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value ​ ​ ​ ​ ​ Accrued ​ ​ Notional ​ Liabilities ​ ​ Amount ​ and Other Derivatives Designated as Hedging Instruments ​ (in millions) Interest rate swap contracts as of March 31, 2021 ​ $ 1,320.1 ​ $ 3.8 Interest rate swap contracts as of December 31, 2020 ​ $ 1,323.5 ​ $ 9.4 ​ Gains and losses on derivatives designated as cash flow hedges included in the unaudited condensed consolidated statements of comprehensive income (loss) for the three months ended March 31, 2021 and 2020 are shown in the table below: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended ​ ​ March 31, ​ 2021 2020 Interest rate swap contracts(1) ​ (in millions) Gain (loss) recorded in AOCL on derivatives, before tax ​ $ 5.6 ​ $ (3.9) Tax impact ​ ​ (1.3) ​ ​ 0.9 Gain (loss) recorded in AOCL on derivatives, net ​ ​ 4.3 ​ ​ (3.0) (1) Gains (losses) on derivatives reclassified from AOCL into income will be included in “Interest expense” in the unaudited condensed consolidated statements of operations, the same income statement line item as the earnings effect of the hedged item. Losses recognized in the unaudited condensed consolidated statements of operations for the three months ended March 31, 2021 and 2020 total $5.7 million and $3.8 million, respectively. For the periods presented, all cash flows associated with derivatives are classified as operating cash flows in the unaudited condensed consolidated statements of cash flows.

Income Taxes
Income Taxes	Note 11. Income Taxes The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets and liabilities 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 on deferred tax assets and liabilities of changes in tax rates is reflected in the financial statements in the period that includes the date of enactment. The Company reported income tax expense of $0.9 million and $0.8 million for the three months ended March 31, 2021 and 2020, respectively. The slight increase in expense is primarily related to an increase in income before tax while the lower effective income tax rate was primarily driven by the windfall deduction related to equity compensation, an increase in the research and development credit, and a decrease in state valuation allowance. The near breakeven income before tax for the three months ended March 31, 2020 resulted in tax adjustments having a larger impact on the effective tax rate as compared to the three months ended March 31, 2021. ​

Kirkland Kirkland ​ Sprint Patent Infringement Claim ​ 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, the Company 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. The Company consistently monitors its pending litigation for the purpose of adjusting its accruals and revising its disclosures accordingly, in accordance with GAAP, when required. However, litigation is subject to uncertainty, and the outcome of any particular matter is not predictable. The Company will vigorously defend its interests in pending litigation, and the Company 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 consolidated financial position, results of operations, or cash flows. ​

Summary of Significant Accounting Policies
Principles of Consolidation	Principles of Consolidation and Basis of Presentation The accompanying 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. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission (“SEC”); however, in the opinion of management, the disclosures made are adequate to ensure the information presented is not misleading. The year-end 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 2020 Annual Report filed with the SEC on February 24, 2021. All significant intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires 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, including but not limited to the potential impacts arising from COVID-19. 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 ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ​ In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 provides optional guidance, expedients and exceptions for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this update apply to all entities, subject to meeting the criteria, which participate in contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. ASU 2020-04 was subsequently amended by ASU 2021-01, Reference Rate Reform (Topic 848), Scope, which refines the scope of Topic 848 and permits optional expendients and exceptions when accounting for derivative contracts and certain hedging relationships. The amendments of these updates are available to all entities as of March 12, 2020 through December 31, 2022. The Company has not yet adopted these amendments, but has determined the impact of adopting this guidance will not have a material impact on its financial position, results of operations and cash flows. ​ Recently Adopted Accounting Pronouncements ASU 2019-12, Income Taxes —Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted this guidance prospectively as of January 1, 2021. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows.
