Segment Reporting. 280 Segment Reporting Use of Estimates. may Revenue Recognition. 606 Revenue from Contracts with Customers . one The Company also generally receives an allocation of scheduled advertising time as part of its distribution agreements with cable and broadcast networks, which the Company sells to local, regional and national advertisers under contracts with terms that are typically less than one third not The unit of accounting for revenue recognition is a performance obligation, which is a requirement to transfer a distinct good or service to a customer. Customers are billed for the services to which they subscribe based upon published or contracted rates, with the sales price being allocated to each performance obligation. For arrangements with multiple performance obligations, the sales price is allocated based on the relative standalone selling price for each subscribed service. Generally, performance obligations are satisfied, and revenue is recognized, over the period of time in which customers simultaneously receive and consume the Company’s defined performance obligations, which are delivered in a similar pattern of transfer. Advertising revenue is recognized at the point in time when the underlying performance obligation is complete. The Company also incurs certain incremental costs to acquire residential and business customers, such as commission costs and third tely five Fees imposed on the Company by various governmental authorities, including franchise fees, are passed through on a monthly basis to the Company’s customers and are periodically remitted to authorities. As the Company acts as principal, these fees are reported in video and voice revenues on a gross basis with corresponding expenses included within operating expenses in the consolidated statements of operations and comprehensive income. Concentrations of Credit Risk. Programming Costs. Advertising Costs 2021 2020 2019 Cash Equivalents three Allowance for Credit Losses. may Fair Value Measurements. three 1 2 3 may For assets and liabilities that are measured using quoted prices in active markets, the total fair value is the published market price per unit multiplied by the number of units held, without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs are primarily valued by reference to quoted prices of similar assets or liabilities in active markets, adjusted for any terms specific to that asset or liability. Assets and liabilities that are measured using significant unobservable inputs are valued using various valuation techniques, including Monte Carlo simulations. The Company measures certain assets, including property, plant and equipment, intangible assets and goodwill, at fair value on a nonrecurring basis when they are deemed to be impaired. The fair value of these assets is determined with valuation techniques using the best information available and may The carrying amounts reported in the Company’s consolidated financial statements for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value because of the short-term nature of these financial instruments. Equity Investments. not Equity investments that do provide the Company with the ability to exert significant influence over the operating or financial decisions of the investee are accounted for under the equity method. The equity method requires the initial fair value of the investment to be recorded as an asset within the consolidated balance sheet. Based on its ownership percentage, the Company then recognizes its proportionate share of the investee’s net income (loss) each period within equity method investment income (loss) in the consolidated statement of operations and comprehensive income and a corresponding increase (decrease) to the investment’s carrying value within the consolidated balance sheet. As permitted by GAAP, the Company elected to recognize its proportionate share of such net income (loss) for each of its equity method investments on a one For each of the Company’s equity investments that have readily determinable fair values, the Company assesses each investment for indicators of impairment on a quarterly basis based primarily on the investee’s most recently available financial and operating information. If it is determined that the fair value of an investment has fallen below its carrying value, the carrying value is adjusted down to fair value and an impairment loss equal to the amount of the adjustment is recognized within the period’s statement of operations and comprehensive income.

Cable distribution systems 5 25 Customer premise equipment 3 5 Other equipment and fixtures 3 10 Buildings and improvements 10 20 Capitalized software 3 7 Right-of-use (“ROU”) assets 1 5 The costs of leasehold improvements are amortized over the lesser of their useful lives or the remaining terms of the respective leases. Costs associated with the installation and upgrade of services and acquiring and deploying of customer premise equipment, including materials, internal and external labor costs and related indirect and overhead costs, are capitalized. Capitalized labor costs include the direct costs of engineers and technical personnel involved in the design and implementation of plant and infrastructure; the costs of technicians involved in the installation and upgrades of services and customer premise equipment; and the costs of support personnel directly involved in capitalizable activities, such as project managers and supervisors. These costs are capitalized based on internally developed standards by position, which are updated annually (or more frequently if required). These standards are developed utilizing a combination of actual costs incurred where applicable, survey information, operational data and management judgment. Overhead costs are capitalized based on standards developed from historical information. Indirect and overhead costs include payroll taxes; insurance and other benefits; and vehicle, tool and supply expense related to installation activities. Costs for repairs and maintenance, disconnecting service or reconnecting service are expensed as incurred.

These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, the Company’s equity-based compensation expense could be materially different for future SAR grants. The assumptions for 2021 ● Fair Value of Common Stock — Valued by reference to the closing price of the Company’s publicly traded common stock on the date of grant. ● Expected Volatility — The Company estimated the expected future stock price volatility for its common stock by using its life-to-date historical volatility based on daily price observations since it became a publicly traded company on July 1, 2015. ● Risk-Free Interest Rate — The risk-free interest rate assumption was based on the yields of U.S. Treasury securities with maturities similar to the expected term of the SARs being valued. ● Expected Term — The expected term represents the period that the Company’s SARs are expected to be outstanding. The expected term of the Company’s SARs is based on the “simplified method” which defines the expected term as the average of the contractual term and the weighted-average vesting period for all tranches. ● Expected Dividend Yield — The Company expects to continue to pay quarterly dividends in the future and, as such, the expected dividend yield was calculated as the Company’s current annual dividend divided by the Company’s closing stock price on the grant date.

Customers are billed for the services to which they subscribe based upon published or contracted rates, with the sales price being allocated to each performance obligation. For arrangements with multiple performance obligations, the sales price is allocated based on the relative standalone selling price for each subscribed service. Generally, performance obligations are satisfied, and revenue is recognized, over the period of time in which customers simultaneously receive and consume the Company’s defined performance obligations, which are delivered in a similar pattern of transfer. Advertising revenue is recognized at the point in time when the underlying performance obligation is complete. The Company also incurs certain incremental costs to acquire residential and business customers, such as commission costs and third tely five Fees imposed on the Company by various governmental authorities, including franchise fees, are passed through on a monthly basis to the Company’s customers and are periodically remitted to authorities.

Fair Value Measurement, Policy [Policy Text Block]	Fair Value Measurements. three 1 2 3 may For assets and liabilities that are measured using quoted prices in active markets, the total fair value is the published market price per unit multiplied by the number of units held, without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs are primarily valued by reference to quoted prices of similar assets or liabilities in active markets, adjusted for any terms specific to that asset or liability. Assets and liabilities that are measured using significant unobservable inputs are valued using various valuation techniques, including Monte Carlo simulations. The Company measures certain assets, including property, plant and equipment, intangible assets and goodwill, at fair value on a nonrecurring basis when they are deemed to be impaired. The fair value of these assets is determined with valuation techniques using the best information available and may The carrying amounts reported in the Company’s consolidated financial statements for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value because of the short-term nature of these financial instruments.
Investment, Policy [Policy Text Block]	Equity Investments. not Equity investments that do provide the Company with the ability to exert significant influence over the operating or financial decisions of the investee are accounted for under the equity method. The equity method requires the initial fair value of the investment to be recorded as an asset within the consolidated balance sheet. Based on its ownership percentage, the Company then recognizes its proportionate share of the investee’s net income (loss) each period within equity method investment income (loss) in the consolidated statement of operations and comprehensive income and a corresponding increase (decrease) to the investment’s carrying value within the consolidated balance sheet. As permitted by GAAP, the Company elected to recognize its proportionate share of such net income (loss) for each of its equity method investments on a one For each of the Company’s equity investments that have readily determinable fair values, the Company assesses each investment for indicators of impairment on a quarterly basis based primarily on the investee’s most recently available financial and operating information. If it is determined that the fair value of an investment has fallen below its carrying value, the carrying value is adjusted down to fair value and an impairment loss equal to the amount of the adjustment is recognized within the period’s statement of operations and comprehensive income.

[1]	Consists of approximately $2.0 billion of cash for the additional approximately 85% equity interest in Hargray that the Company did not already own and the $146.6 million May 3, 2021 fair value of the Company’s existing approximately 15% equity investment in Hargray. The Company recognized a $33.4 million non-cash gain within other income in the consolidated statement of operations and comprehensive income upon the acquisition, representing the difference between the existing equity investment’s fair value and $113.2 million carrying value. The fair value of the existing investment was calculated as approximately 15% of the fair value of Hargray’s total equity value (determined using the discounted cash flow method of the income approach, less debt), excluding the impact of any synergies or control premium that would be realized by a controlling interest.

Refer to notes 6 and 13 for further information on the MBI Net Option (as defined in note 6).
[2]	The Company holds a call option to purchase all but not less than all of the remaining equity interests in MBI that the Company does not already own between January 1, 2023 and June 30, 2024. If the call option is not exercised, certain investors in MBI hold a put option to sell (and to cause all members of MBI other than the Company to sell) to the Company all but not less than all of the remaining equity interests in MBI that the Company does not already own between July 1, 2025 and September 30, 2025. The call and put options (collectively referred to as the "MBI Net Option") are measured at fair value using Monte Carlo simulations that rely on assumptions around MBI’s equity value, MBI’s and the Company’s equity volatility, MBI’s and the Company’s EBITDA volatility, risk adjusted discount rates and the Company’s cost of debt, among others. The final MBI purchase price allocation resulted in $630.7 million being allocated to the MBI equity investment and $19.7 million and $75.5 million being allocated to the call and put options, respectively. The MBI Net Option is remeasured at fair value on a quarterly basis. The carrying value of the MBI Net Option liability was $123.6 million and $73.3 million as of December 31, 2021 and December 31, 2020, respectively, and was included within other noncurrent liabilities in the consolidated balance sheets.

[1]	The Company holds a call option to purchase all but not less than all of the remaining equity interests in MBI that the Company does not already own between January 1, 2023 and June 30, 2024. If the call option is not exercised, certain investors in MBI hold a put option to sell (and to cause all members of MBI other than the Company to sell) to the Company all but not less than all of the remaining equity interests in MBI that the Company does not already own between July 1, 2025 and September 30, 2025. The call and put options (collectively referred to as the "MBI Net Option") are measured at fair value using Monte Carlo simulations that rely on assumptions around MBI’s equity value, MBI’s and the Company’s equity volatility, MBI’s and the Company’s EBITDA volatility, risk adjusted discount rates and the Company’s cost of debt, among others.

The MBI Net Option is remeasured at fair value on a quarterly basis. The carrying value of the MBI Net Option liability was $123.6 million and $73.3 million as of December 31, 2021 and December 31, 2020, respectively, and was included within other noncurrent liabilities in the consolidated balance sheets. Refer to note 13 for further information on the MBI Net Option.
[2]	As a result of the Company’s May 3, 2021 acquisition of the remaining equity interests in Hargray that it did not already own, Hargray’s assets and liabilities were separately reflected within the Company’s consolidated balance sheet as of the acquisition date and the existing cost method investment was eliminated, resulting in a $33.4 million non-cash gain recognized within other income in the condensed consolidated statement of operations and comprehensive income on the acquisition date.
[3]	Upon initial investment, the Company calculated the fair value of Hargray’s total enterprise value using a hybrid of both the discounted cash flow method of the income approach and the guideline public company method of the market approach. Significant assumptions used in the valuation include projected revenue growth rates, future EBITDA margins, future capital expenditures and an appropriate discount rate. The enterprise value less Hargray’s debt and unamortized debt issuance costs was multiplied by Cable One’s minority equity interest percentage to determine the Hargray investment’s carrying value. The resulting $82.6 million non-cash gain was calculated as the difference between this carrying value and the book value of the Anniston System’s net assets, including its proportionate share of the Company’s franchise agreement and goodwill assets. The approximately 15% equity interest in Hargray as of December 31, 2020 was on a fully diluted basis.
