Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	1. ORGANIZATION Mediacom Broadband LLC (“Mediacom Broadband” and collectively with its subsidiaries, “we,” “our” or “us”) is a Delaware limited liability company wholly-owned by Mediacom Communications Corporation (“MCC”). MCC is involved in the acquisition and operation of cable systems serving smaller cities and towns in the United States, and its cable systems are owned and operated through our operating subsidiaries and those of Mediacom LLC, a New York limited liability company wholly-owned by MCC. As limited liability companies, we and Mediacom LLC are not subject to income taxes and, as such, are included in the consolidated federal and state income tax returns of MCC, a C corporation. Our principal operating subsidiaries conduct all of our consolidated operations and own substantially all of our consolidated assets. Our operating subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to make funds available to us. We rely on our parent, MCC, for various services such as corporate and administrative support. Our financial position, results of operations and cash flows could differ from those that would have resulted had we operated autonomously or as an entity independent of MCC. See Notes 8 and 9. Mediacom Broadband Corporation, a Delaware corporation wholly-owned by us, co-issued, jointly and severally with us, public debt securities. Mediacom Broadband Corporation has no operations, revenues or cash flows and has no assets, liabilities or stockholders’ equity on its balance sheet, other than a one-hundred dollar receivable from an affiliate and the same dollar amount of common stock. Therefore, separate financial statements have not been presented for this entity.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Preparation of Consolidated Financial Statements The consolidated financial statements include the accounts of us and our subsidiaries. All significant intercompany transactions and balances have been eliminated. Comprehensive income is equal to net income for all periods presented. The preparation of the consolidated financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The accounting estimates that require management’s most difficult and subjective judgments include: assessment and valuation of intangibles, accounts receivable allowance, useful lives of property, plant and equipment and capitalized labor. Actual results could differ from those and other estimates. Reclassifications Certain reclassifications have been made to prior year amounts to conform to the current year presentation. Revenue Recognition Video, high speed data (“HSD”), phone and business services revenues are recognized when the services are provided to our customers. We generally bill customers in advance for the services and equipment they have chosen to use and record such amounts as deferred revenue until the services are provided and the equipment is used. Credit risk is managed by disconnecting services to customers who are deemed to be delinquent. Installation revenues are recognized as customer connections are completed because installation revenues are less than direct installation costs. Advertising sales are recognized in the period that the advertisements are exhibited. Deposits and up-front Allowance for Doubtful Accounts The allowance for doubtful accounts represents our best estimate of probable losses in the accounts receivable balance. The allowance is based on the number of days outstanding, customer balances, recoveries, historical experience and other currently available information. Concentration of Credit Risk Our accounts receivable are comprised of amounts due from customers in varying regions throughout the United States. Concentration of credit risk with respect to these receivables is limited due to the large number of customers comprising our customer base and their geographic dispersion. We invest our cash with high quality financial institutions. Property, Plant and Equipment Property, plant and equipment are recorded at cost. Additions to property, plant and equipment generally include material, labor and indirect costs. Depreciation is calculated on a straight-line basis over the following useful lives: Buildings 40 years Leasehold improvements Lesser of: life of respective lease or life of asset Cable systems, equipment and customer devices 5-20 years Vehicles 4-5 years Furniture, fixtures, and office equipment 5 years We capitalize improvements that extend asset lives and expense repairs and maintenance as incurred. At the time of retirements, write-offs, sales or other dispositions of property, the original cost and related accumulated depreciation are removed from the respective accounts and any resulting gains or losses are included in depreciation and amortization expense in the consolidated statement of operations. We capitalize the costs associated with the construction of cable transmission and distribution facilities, new customer installations and indirect costs associated with our phone service. Costs include direct labor and material, as well as certain indirect costs including capitalized interest. We perform periodic evaluations of the estimates used to determine the amount and extent that such costs are capitalized. Any changes to these estimates, which may be significant, are applied in the period in which the evaluations were completed. The costs of disconnecting service at a customer’s dwelling or reconnecting to a previously installed dwelling are charged as expense in the period incurred. Costs associated with subsequent installations of additional services not previously installed at a customer’s dwelling are capitalized to the extent such costs are incremental and directly attributable to the installation of such additional services. See Note 3. Capitalized Software Costs We account for internal-use 350-40- Intangibles-Goodwill and Other: Internal-Use Marketing and Promotional Costs Marketing and promotional costs are expensed as incurred and were $35.7 million, $31.9 million and $24.3 million for the years ended December 31, 2016, 2015 and 2014, respectively. Intangible Assets Our cable systems operate under non-exclusive Intangibles — Goodwill and Other We follow the provisions of ASC 350 to test our goodwill and franchise rights for impairment. We assess the fair values of our reporting unit using the Excess Earnings Method of the Income Approach as our discounted cash flow (“DCF”) methodology, under which the fair value of cable franchise rights are determined in a direct manner. We employ the Multi-Period Excess Earnings Method to calculate the fair values of our cable franchise rights, using unobservable inputs (Level 3). This assessment involves significant judgment, including certain assumptions and estimates that determine future cash flow expectations and other future benefits, which are consistent with the expectations of buyers and sellers of cable systems in determining fair value. These assumptions and estimates include discount rates, estimated growth rates, terminal growth rates, comparable company data, revenues per customer, market penetration as a percentage of homes passed and operating margin. We also consider market transactions, market valuations, research analyst estimates and other valuations using multiples of operating income before depreciation and amortization to confirm the reasonableness of fair values determined by the DCF methodology. We also employ the Greenfield model to corroborate the fair values of our cable franchise rights determined under the In-use Based on the guidance outlined in ASC 350, we have determined that the unit of accounting or reporting unit, for testing goodwill and franchise rights is Mediacom Broadband. Comprising cable system clusters across several states, Mediacom Broadband is at the financial reporting level that is managed and reviewed by the corporate office (i.e., chief operating decision maker) including our determination as to how we allocate capital resources and utilize the assets. The reporting unit level also reflects the level at which the purchase method of accounting for our acquisitions was originally recorded. In accordance with ASC 350, we are required to determine goodwill impairment using a two-step The impairment test for our franchise rights and other intangible assets not subject to amortization consists of a comparison of the fair value of the intangible asset with its carrying value. If the carrying value of the intangible asset exceeds its fair value, the excess is recognized as an impairment loss. Since our adoption of ASC 350 in 2002, we have not recorded any impairments as a result of our impairment testing. We completed our most recent impairment test as of October 1, 2016, which reflected no impairment of our franchise rights, goodwill or other intangible assets. We could record impairments in the future if there are changes in the long-term fundamentals of our business, in general market conditions or in the regulatory landscape that could prevent us from recovering the carrying value of our long-lived intangible assets. The economic conditions affecting the U.S. economy, and how that may impact the fundamentals of our business, may have a negative impact on the fair values of the assets in our reporting unit. In accordance with Accounting Standards Update No. 2010-28 When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts (a consensus of the FASB Emerging Issues Task Force) The following table details changes in the carrying value of goodwill for the years ended December 31, 2016 and 2015 (dollars in thousands): Balance - December 31, 2014 $ 195,945 Acquisitions — Dispositions — Balance - December 31, 2015 $ 195,945 Acquisitions — Dispositions — Balance - December 31, 2016 $ 195,945 Segment Reporting ASC 280 — Segment Reporting Accounting for Derivative Instruments We account for derivative instruments in accordance with ASC 815 — Derivatives and Hedging one-to-one Accounting for Asset Retirement We adopted ASC 410 — Asset Retirement Obligations rights-of-way Upon adoption of ASC 410, we determined that in certain instances, we are obligated by contractual terms or regulatory requirements to remove facilities or perform other remediation activities upon the retirement of our assets. We initially recorded a $1.8 million asset in property, plant and equipment and a corresponding liability of $1.8 million. As of both December 31, 2016 and 2015, the corresponding asset, net of accumulated amortization, was $0. Accounting for Long-Lived Assets In accordance with ASC 360 — Property, Plant and Equipment Programming Costs We have various fixed-term carriage contracts to obtain programming for our cable systems from content suppliers whose compensation is generally based on a fixed monthly fee per video customer. These programming contracts are subject to negotiated renewal. Programming costs are recognized when we distribute the related programming. These programming costs are usually payable each month based on calculations performed by us and are subject to adjustments based on the results of periodic audits by the content suppliers. Historically, such audit adjustments have been immaterial to our total programming costs. Financial incentives, when received, are deferred within non-current Recent Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09 (“ASU 2014-09”) – Revenue from Contracts with Customers Financial Reporting by Cable Television Companies ASU 2014-09 ASU 2014-09 In August 2014, the FASB issued new guidance that requires management to assess the Company’s ability to continue as a going concern and to provide related disclosures in certain circumstances. This guidance is effective for interim and fiscal years ending after December 15, 2016, with early adoption permitted. This guidance did not have a material impact on our financial position, operations or cash flows. In April 2015 (as amended in August 2015), the FASB issued ASU No. 2015-03 2015-15) Interest—Imputation of Interest 835-30) Simplifying the Presentation of Debt Issuance Costs 2015-03”). 2015-03 2015-15 In April 2015, the FASB issued ASU 2015-05 Intangibles—Goodwill and Other—Internal-Use 350-40) 2015-05”). 2015-05 2015-05 paid by a customer in a cloud computing arrangement by providing guidance as to whether an arrangement includes the sale or license of software. Examples of cloud computing arrangements include software as a service, platform as a service, infrastructure as a service, and other similar hosting arrangements. This guidance is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. We adopted this new guidance as of January 1, 2016 and determined that there was not a material impact to our operations.

Fair Value	4. FAIR VALUE The tables below set forth our financial assets and liabilities measured at fair value on a recurring basis using a market-based approach. Our financial assets and liabilities, all of which represent interest rate exchange agreements (which we refer to as “interest rate swaps”) have been categorized according to the three-level fair value hierarchy established by ASC 820 – Fair Value Measurement • Level 1 — Quoted market prices in active markets for identical assets or liabilities. • Level 2 — Observable market based inputs or unobservable inputs that are corroborated by market data. • Level 3 — Unobservable inputs that are not corroborated by market data. Fair Value as of December 31, 2016 Level 1 Level 2 Level 3 Total Assets Interest rate exchange agreements $ — $ 1,089 $ — $ 1,089 Liabilities Interest rate exchange agreements $ — $ 1,763 $ — $ 1,763 Fair Value as of December 31, 2015 Level 1 Level 2 Level 3 Total Assets Interest rate exchange agreements $ — $ 1,818 $ — $ 1,818 Liabilities Interest rate exchange agreements $ — $ 3,695 $ — $ 3,695 The fair value of our interest rate swaps represents the estimated amount that we would receive or pay to terminate such agreements, taking into account projected interest rates, based on quoted London Interbank Offered Rate (“LIBOR”) futures and the remaining time to maturity. While our interest rate swaps are subject to contractual terms that provide for the net settlement of transactions with counterparties, we do not offset assets and liabilities under these agreements for financial statement presentation purposes, and assets and liabilities are reported on a gross basis. As of December 31, 2016, we recorded a long-term asset of $1.1 million, a current liability in accounts payable, accrued expenses and other current liabilities of $1.8 million and no current asset or long-term liability. As of December 31, 2015, we recorded a long-term asset of $1.8 million, a current liability in accounts payable, accrued expenses and other current liabilities of $3.7 million and no current asset or long-term liability.

The credit facility is collateralized by our ownership interests in our operating subsidiaries and is guaranteed by us on a limited recourse basis to the extent of such ownership interests. As of December 31, 2016, we had the ability to repay all outstanding debt under the credit facility at par value any time prior to maturity. As of December 31, 2016, the credit agreement governing the credit facility (the “credit agreement”) required our operating subsidiaries to maintain a total leverage ratio (as defined in the credit agreement) of no more than 5.0 to 1.0 and an interest coverage ratio (as defined in the credit agreement) of no less than 2.0 to 1.0. For all periods through December 31, 2016, our operating subsidiaries were in compliance with all covenants under the credit agreement. Revolving Credit Commitments On October 10, 2014, we terminated our existing revolving credit commitments and, on the same date, entered into an incremental facility agreement that provided for $216.0 million of new revolving credit commitments, which are scheduled to expire on October 10, 2019. On December 9, 2014, August 12, 2015 and November 23, 2015, we entered into incremental facility agreements that provided for an additional $40.0 million, $25.0 million and $87.5 million of revolving credit commitments, respectively. Borrowings under our revolving credit commitments bear interest at a floating rate or rates equal to, at our discretion, LIBOR plus a margin ranging from 2.00% to 2.75%, or the Prime Rate plus a margin ranging from 1.00% to 1.75%. Commitment fees on the unused portion of our revolving credit commitments are payable at a rate of 0.50% or 0.63%. The applicable margin and commitment fees charged are determined by certain financial ratios pursuant to the credit agreement. As of December 31, 2016, we had $246.2 million of unused revolving credit commitments, all of which were available to be borrowed and used for general corporate purposes, after giving effect to $112.6 million of outstanding loans and $9.7 million of letters of credit issued to various parties as collateral. Term Loan A On December 17, 2015, we entered into an incremental facility agreement that provided for a new term loan in the original principal amount of $151.5 million (“Term Loan A”). Term Loan A matures on January 15, 2021 and, since March 31, 2016, has been subject to quarterly principal payments of $1.9 million, representing 1.25% of the original principal amount, with a final payment at maturity of $113.6 million, representing 75.00% of the original principal amount. Borrowings under Term Loan A bear interest at a floating rate or rates equal to, at our discretion, LIBOR plus a margin ranging from 2.25% to 3.50%, or the Prime Rate plus a margin ranging from 1.25% to 2.50%. The applicable margin and commitment fees charged are determined by certain financial ratios pursuant to the credit agreement. Term Loan H On May 29, 2013, we entered into an incremental facility agreement that provided for a new term loan in the original principal amount of $600.0 million (“Term Loan H”). Term Loan H matures on January 29, 2021 and, since September 30, 2013, has been subject to quarterly principal payments of $1.5 million, representing 0.25% of the original principal amount, with a final payment at maturity of $555.0 million, representing 92.5% of the original principal amount. Borrowings under Term Loan H bear interest at a floating rate or rates equal to, at our discretion, LIBOR plus a margin of 2.50% (subject to a minimum LIBOR of 0.75%), or the Prime Rate plus a margin of 1.50% (subject to a minimum Prime Rate of 1.75%). Term Loan J On June 20, 2014, we entered into an amended and restated credit agreement that, among other things, provided for a new term loan in the original principal amount $300.0 million (“Term Loan J”). Term Loan J matures on June 30, 2021 and, since September 30, 2014, has been subject to quarterly principal payments of $0.8 million, representing 0.25% of the original principal amount, with a final payment at maturity of $279.8 million, representing 93.25% of the original principal amount.

The applicable margin charged is determined by certain financial ratios pursuant to the credit agreement. Interest Rate Swaps We have entered into several interest rate exchange agreements (which we refer to as “interest rate swaps”) with various banks to fix the variable rate on a portion of our borrowings under the credit facility to reduce the potential volatility in our interest expense that may result from changes in market interest rates. Our interest rate swaps have not been designated as hedges for accounting purposes, and have been accounted for on a mark-to-market As of December 31, 2016, the weighted average interest rate on outstanding borrowings under the credit facility, including the effect of our interest rate swaps, was 3.5%. Senior Notes As of December 31, 2016, we had $500.0 million of outstanding senior notes, comprising $200.0 million of 5 1 2 1 2 3 8 3 8 Our senior notes are unsecured obligations and, as of December 31, 2016, the indentures governing our senior notes (the “indentures”) limits the incurrence of additional indebtedness based upon a maximum debt to operating cash flow ratio (as defined in the indentures) of 8.5 to 1.0. For all periods through December 31, 2016, we were in compliance with all of the covenants under the indentures. 5 1 2 On March 17, 2014, we issued the 5 1 2 1 2 As a percentage of par value, the 5 1 2 6 3 8 On August 28, 2012, we issued the 6 3 8 3 8 As a percentage of par value, the 6 3 8 Loss on Early Extinguishment of Debt Loss on early extinguishment of debt totaled $1.2 million, $4.4 million and $0.3 million for the years ended December 31, 2016, 2015 and 2014, respectively, which represented the write-off Deferred Financing Costs We adopted ASU 2015-03 2015-15 Debt Ratings MCC’s corporate credit ratings are currently Ba3 by Moody’s, with a positive outlook, and BB by Standard and Poor’s (“S&P”), with a stable outlook, and our senior unsecured ratings are currently B2 by Moody’s, with a positive outlook, and B+ by S&P, with a stable outlook. There are no covenants, events of default, borrowing conditions or other terms in the credit agreement or indentures that are based on changes in our credit rating assigned by any rating agency. Fair Value and Debt Maturities The fair values of our senior notes and outstanding debt under the credit facility (which were calculated based upon market prices of such issuances in an active market when available) were as follows as of December 31, 2016 and 2015 (dollars in thousands): December 31, 2016 2015 5 1 2 $ 205,500 $ 191,500 6 3 8 316,500 291,750 Total senior notes $ 522,000 $ 483,250 Bank credit facility $ 1,135,633 $ 1,317,990 The scheduled maturities of all debt outstanding as of December 31, 2016 are as follows (dollars in thousands): Bank Credit Facility Senior Revolving Credit Term Loans Notes Total January 1, 2017 to December 31, 2017 $ — $ 16,575 $ — $ 16,575 January 1, 2018 to December 31, 2018 — 16,575 — 16,575 January 1, 2019 to December 31, 2019 112,575 16,575 — 129,150 January 1, 2020 to December 31, 2020 — 16,575 — 16,575 January 1, 2021 to December 31, 2021 — 949,125 200,000 1,149,125 Thereafter — — 300,000 300,000 Total $ 112,575 $ 1,015,425 $ 500,000 $ 1,628,000

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Preparation of Consolidated Financial Statements	Basis of Preparation of Consolidated Financial Statements The consolidated financial statements include the accounts of us and our subsidiaries. All significant intercompany transactions and balances have been eliminated. Comprehensive income is equal to net income for all periods presented. The preparation of the consolidated financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The accounting estimates that require management’s most difficult and subjective judgments include: assessment and valuation of intangibles, accounts receivable allowance, useful lives of property, plant and equipment and capitalized labor. Actual results could differ from those and other estimates.
Reclassifications	Reclassifications Certain reclassifications have been made to prior year amounts to conform to the current year presentation.
Revenue Recognition	Revenue Recognition Video, high speed data (“HSD”), phone and business services revenues are recognized when the services are provided to our customers. We generally bill customers in advance for the services and equipment they have chosen to use and record such amounts as deferred revenue until the services are provided and the equipment is used. Credit risk is managed by disconnecting services to customers who are deemed to be delinquent. Installation revenues are recognized as customer connections are completed because installation revenues are less than direct installation costs. Advertising sales are recognized in the period that the advertisements are exhibited. Deposits and up-front
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The allowance for doubtful accounts represents our best estimate of probable losses in the accounts receivable balance. The allowance is based on the number of days outstanding, customer balances, recoveries, historical experience and other currently available information.
Concentration of Credit Risk	Concentration of Credit Risk Our accounts receivable are comprised of amounts due from customers in varying regions throughout the United States. Concentration of credit risk with respect to these receivables is limited due to the large number of customers comprising our customer base and their geographic dispersion. We invest our cash with high quality financial institutions.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are recorded at cost. Additions to property, plant and equipment generally include material, labor and indirect costs. Depreciation is calculated on a straight-line basis over the following useful lives: Buildings 40 years Leasehold improvements Lesser of: life of respective lease or life of asset Cable systems, equipment and customer devices 5-20 years Vehicles 4-5 years Furniture, fixtures, and office equipment 5 years We capitalize improvements that extend asset lives and expense repairs and maintenance as incurred. At the time of retirements, write-offs, sales or other dispositions of property, the original cost and related accumulated depreciation are removed from the respective accounts and any resulting gains or losses are included in depreciation and amortization expense in the consolidated statement of operations. We capitalize the costs associated with the construction of cable transmission and distribution facilities, new customer installations and indirect costs associated with our phone service. Costs include direct labor and material, as well as certain indirect costs including capitalized interest. We perform periodic evaluations of the estimates used to determine the amount and extent that such costs are capitalized. Any changes to these estimates, which may be significant, are applied in the period in which the evaluations were completed. The costs of disconnecting service at a customer’s dwelling or reconnecting to a previously installed dwelling are charged as expense in the period incurred. Costs associated with subsequent installations of additional services not previously installed at a customer’s dwelling are capitalized to the extent such costs are incremental and directly attributable to the installation of such additional services. See Note 3.
Capitalized Software Costs	Capitalized Software Costs We account for internal-use 350-40- Intangibles-Goodwill and Other: Internal-Use
Marketing and Promotional Costs	Marketing and Promotional Costs Marketing and promotional costs are expensed as incurred and were $35.7 million, $31.9 million and $24.3 million for the years ended December 31, 2016, 2015 and 2014, respectively.
Intangible Assets	Intangible Assets Our cable systems operate under non-exclusive Intangibles — Goodwill and Other We follow the provisions of ASC 350 to test our goodwill and franchise rights for impairment. We assess the fair values of our reporting unit using the Excess Earnings Method of the Income Approach as our discounted cash flow (“DCF”) methodology, under which the fair value of cable franchise rights are determined in a direct manner. We employ the Multi-Period Excess Earnings Method to calculate the fair values of our cable franchise rights, using unobservable inputs (Level 3). This assessment involves significant judgment, including certain assumptions and estimates that determine future cash flow expectations and other future benefits, which are consistent with the expectations of buyers and sellers of cable systems in determining fair value. These assumptions and estimates include discount rates, estimated growth rates, terminal growth rates, comparable company data, revenues per customer, market penetration as a percentage of homes passed and operating margin. We also consider market transactions, market valuations, research analyst estimates and other valuations using multiples of operating income before depreciation and amortization to confirm the reasonableness of fair values determined by the DCF methodology. We also employ the Greenfield model to corroborate the fair values of our cable franchise rights determined under the In-use Based on the guidance outlined in ASC 350, we have determined that the unit of accounting or reporting unit, for testing goodwill and franchise rights is Mediacom Broadband. Comprising cable system clusters across several states, Mediacom Broadband is at the financial reporting level that is managed and reviewed by the corporate office (i.e., chief operating decision maker) including our determination as to how we allocate capital resources and utilize the assets. The reporting unit level also reflects the level at which the purchase method of accounting for our acquisitions was originally recorded. In accordance with ASC 350, we are required to determine goodwill impairment using a two-step The impairment test for our franchise rights and other intangible assets not subject to amortization consists of a comparison of the fair value of the intangible asset with its carrying value. If the carrying value of the intangible asset exceeds its fair value, the excess is recognized as an impairment loss. Since our adoption of ASC 350 in 2002, we have not recorded any impairments as a result of our impairment testing. We completed our most recent impairment test as of October 1, 2016, which reflected no impairment of our franchise rights, goodwill or other intangible assets. We could record impairments in the future if there are changes in the long-term fundamentals of our business, in general market conditions or in the regulatory landscape that could prevent us from recovering the carrying value of our long-lived intangible assets. The economic conditions affecting the U.S. economy, and how that may impact the fundamentals of our business, may have a negative impact on the fair values of the assets in our reporting unit. In accordance with Accounting Standards Update No. 2010-28 When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts (a consensus of the FASB Emerging Issues Task Force) The following table details changes in the carrying value of goodwill for the years ended December 31, 2016 and 2015 (dollars in thousands): Balance - December 31, 2014 $ 195,945 Acquisitions — Dispositions — Balance - December 31, 2015 $ 195,945 Acquisitions — Dispositions — Balance - December 31, 2016 $ 195,945

Accounting for Asset Retirement	Accounting for Asset Retirement We adopted ASC 410 — Asset Retirement Obligations rights-of-way Upon adoption of ASC 410, we determined that in certain instances, we are obligated by contractual terms or regulatory requirements to remove facilities or perform other remediation activities upon the retirement of our assets. We initially recorded a $1.8 million asset in property, plant and equipment and a corresponding liability of $1.8 million. As of both December 31, 2016 and 2015, the corresponding asset, net of accumulated amortization, was $0.
Accounting for Long-Lived Assets	Accounting for Long-Lived Assets In accordance with ASC 360 — Property, Plant and Equipment
Programming Costs	Programming Costs We have various fixed-term carriage contracts to obtain programming for our cable systems from content suppliers whose compensation is generally based on a fixed monthly fee per video customer. These programming contracts are subject to negotiated renewal. Programming costs are recognized when we distribute the related programming. These programming costs are usually payable each month based on calculations performed by us and are subject to adjustments based on the results of periodic audits by the content suppliers. Historically, such audit adjustments have been immaterial to our total programming costs. Financial incentives, when received, are deferred within non-current
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09 (“ASU 2014-09”) – Revenue from Contracts with Customers Financial Reporting by Cable Television Companies ASU 2014-09 ASU 2014-09 In August 2014, the FASB issued new guidance that requires management to assess the Company’s ability to continue as a going concern and to provide related disclosures in certain circumstances. This guidance is effective for interim and fiscal years ending after December 15, 2016, with early adoption permitted. This guidance did not have a material impact on our financial position, operations or cash flows.
