1. Organization and Basis of Presentation Organization  WideOpenWest, Inc. (WOW or 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 networks 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. 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, LLC, which is a wholly owned subsidiary of WideOpenWest Holdings, LLC (former Parent). Prior to the IPO, the former Parents investment in WOW consisted of various classes of common units, which have been pushed down to the Company. Subsequent to the IPO, Racecar Acquisition, LLC (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. Basis of Presentation  The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and the rules and regulations of the Securities and Exchange Commission (the SEC).  These accounting principles require management to make assumptions and estimates that affect the reported amounts and disclosures of assets and liabilities, 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. Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation with no effect on the Companys previously reported results of operations, financial position, or cash flows.  Revision of Prior Period Financial Statements  In connection with the preparation of its consolidated financial statements, the Company identified an immaterial error related to the recognition of deferred tax assets related to state bonus depreciation modification in certain states in prior periods. In accordance with SEC Staff Accounting Bulletins SAB Topic 1.M, Assessing Materiality and SAB Topic 1.N Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, the Company evaluated the error, considering both quantitative and qualitative factors, and determined (i) that the related impact was immaterial to its financial statements for any prior annual or interim period, (ii) leaving it uncorrected, however, would misstate the current period, and (iii) that correcting the impact of the error in the respective annual or interim periods would be helpful to understanding our results of operations for the year ended December 31, 2019. Accordingly, the Company has revised previously reported financial information for such immaterial error. A summary of revisions to certain previously reported financial information presented herein for comparative purposes is included in Note 21.
