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. 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 share-based compensation. 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, HSD, phone and business services revenues are recognized when the services are provided to our customers. 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 fees collected from customers are recognized as deferred revenue until the earnings process is complete. Under the terms of our franchise agreements, we are required to pay local franchising authorities up to 5% of our gross revenues derived from providing cable services. We normally pass these fees through to our customers. Because franchise fees are our obligation, we present them on a gross basis with a corresponding expense. Franchise fees reported on a gross basis amounted to approximately $23.9 million, $24.7 million and $24.9 million for the years ended December 31, 2013, 2012 and 2011, respectively. Franchise fees are reported in their respective revenue categories and included in selling, general and administrative expenses.
	Restricted cash and cash equivalents
	Restricted cash and cash equivalents represent funds pledged to insurance carriers as security under a master pledge and security agreement. Pledged funds are invested in short-term, highly liquid investments. We retained ownership of the pledged funds, and under the terms of the pledge and security agreement, we can withdraw any of the funds, with the restrictions removed from such funds, provided comparable substitute collateral is pledged to the insurance carriers. During the year ended December 31, 2011, we redeemed $6.2 million of restricted cash and cash equivalents, representing the entire outstanding balance.
	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			Life of respective lease
	Cable systems and equipment and customer devices			5 to 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 the 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 also Note 3.
	Capitalized Software Costs
	We account for internal-use software development and related costs in accordance with ASC 350-40-Intangibles-Goodwill and Other: Internal-Use Software. Software development and other related costs consist of external and internal costs incurred in the application development stage to purchase and implement the software that will be used in our telephony business. Costs incurred in the development of application and infrastructure of the software is capitalized and will be amortized over our respective estimated useful life of 5 years. During the years ended December 31, 2013 and 2012, we capitalized approximately $0.2 million and $1.0 million, respectively of software development costs. Capitalized software had a net book value of $16.3 million and $16.1 million as of December 31, 2013 and 2012, respectively.
	Marketing and Promotional Costs
	Marketing and promotional costs are expensed as incurred and were $22.6 million, $22.9 million and $20.9 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	Intangible Assets
	Our cable systems operate under non-exclusive cable franchises, or franchise rights, granted by state and local governmental authorities for varying lengths of time. We acquired these cable franchises through acquisitions of cable systems and were accounted for using the purchase method of accounting. As of December 31, 2013, we held 494 franchises in areas located throughout the United States. The value of a franchise is derived from the economic benefits we receive from the right to solicit new customers and to market new products and services, such as digital video, HSD and phone, in a specific market territory. We concluded that our franchise rights have an indefinite useful life since, among other things, there are no legal, regulatory, contractual, competitive, economic or other factors limiting the period over which these franchise rights contribute to our revenues and cash flows. Goodwill is the excess of the acquisition cost of an acquired entity over the fair value of the identifiable net assets acquired. In accordance with ASC No. 350 — Intangibles — Goodwill and Other (“ASC 350”), we do not amortize franchise rights and goodwill. Instead, such assets are tested annually for impairment or more frequently if impairment indicators arise.
	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 Excess Earnings DCF methodology. Significant impairment in value resulting in impairment charges may result if the estimates and assumptions used in the fair value determination change in the future. Such impairments, if recognized, could potentially be material.
	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 LLC. Comprising cable system clusters across several states, Mediacom Broadband LLC 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 process. The first step compares the fair value of a reporting unit with our carrying amount, including goodwill. If the fair value of the reporting unit exceeds our carrying amount, goodwill of the reporting unit is considered not impaired and the second step is unnecessary. If the carrying amount of a reporting unit exceeds our fair value, the second step is performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of the reporting unit’s goodwill, calculated using the residual method, with the carrying amount of that goodwill. If the carrying amount of the goodwill exceeds the implied fair value, the excess is recognized as an impairment loss.
	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, 2013, 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), as of October 1, 2013, we have evaluated whether there are any adverse qualitative factors surrounding our Mediacom Broadband reporting unit (which has a negative carrying value) indicating that a goodwill impairment may exist. We do not believe that it is “more likely than not” that a goodwill impairment exists. As such, we have not performed Step 2 of the goodwill impairment test.
	The following table details changes in the carrying value of goodwill for the years ended December 31, 2013 and 2012, respectively, (dollars in thousands):
	Balance - December 31, 2011		$	195,945
	Acquisitions			—
	Dispositions			—
	Balance - December 31, 2012		$	195,945
	Acquisitions			—
	Dispositions			—
	Balance - December 31, 2013		$	195,945
	Segment Reporting
	ASC 280 — Segment Reporting (“ASC 280”), requires the disclosure of factors used to identify an enterprise’s reportable segments. Our operations are organized and managed on the basis of cable system clusters within our service area. Each cable system cluster derives revenues from the delivery of similar products and services to a customer base that is also similar. Each cable system cluster deploys similar technology to deliver our products and services, operates within a similar regulatory environment and has similar economic characteristics. Management evaluated the criteria for aggregation under ASC 280 and believes that we meet each of the respective criteria set forth. Accordingly, management has identified broadband services as our one reportable segment.
	Accounting for Derivative Instruments
	We account for derivative instruments in accordance with ASC 815 — Derivatives and Hedging (“ASC 815”). These pronouncements require that all derivative instruments be recognized on the balance sheet at fair value. We enter into interest rate swaps to fix the interest rate on a portion of our variable interest rate debt to reduce the potential volatility in our interest expense that would otherwise result from changes in market interest rates. Our derivative instruments are recorded at fair value and are included in other current assets, other assets and other liabilities of our consolidated balance sheet. Our accounting policies for these instruments are based on whether they meet our criteria for designation as hedging transactions, which include the instrument’s effectiveness, risk reduction and, in most cases, a one-to-one matching of the derivative instrument to our underlying transaction. Gains and losses from changes in fair values of derivatives that are not designated as hedges for accounting purposes are recognized in the consolidated statement of operations. We have no derivative financial instruments designated as hedges. Therefore, changes in fair value for the respective periods were recognized in the consolidated statement of operations.
	Accounting for Asset Retirement
	We adopted ASC 410 — Asset Retirement Obligations (“ASC 410”), on January 1, 2003. ASC 410 addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. We reviewed our asset retirement obligations to determine the fair value of such liabilities and if a reasonable estimate of fair value could be made. This entailed the review of leases covering tangible long-lived assets as well as our rights-of-way under franchise agreements. Certain of our franchise agreements and leases contain provisions that require restoration or removal of equipment if the franchises or leases are not renewed. Based on historical experience, we expect to renew our franchise or lease agreements. In the unlikely event that any franchise or lease agreement is not expected to be renewed, we would record an estimated liability. However, in determining the fair value of our asset retirement obligation under our franchise agreements, consideration will be given to the Cable Communications Policy Act of 1984, which generally entitles the cable operator to the “fair market value” for the cable system covered by a franchise, if renewal is denied and the franchising authority acquires ownership of the cable system or effects a transfer of the cable system to another person. Changes in these assumptions based on future information could result in adjustments to estimated liabilities.
	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 December 31, 2013 and 2012, the corresponding asset, net of accumulated amortization, was $0.
	Accounting for Long-Lived Assets
	In accordance with ASC 360 — Property, Plant and Equipment (“ASC 360”), we periodically evaluate the recoverability and estimated lives of our long-lived assets, including property and equipment and intangible assets subject to amortization, whenever events or changes in circumstances indicate that the carrying amount may not be recoverable or the useful life has changed. The measurement for such impairment loss is based on the fair value of the asset, typically based upon the future cash flows discounted at a rate commensurate with the risk involved. Unless presented separately, the loss is included as a component of either depreciation expense or amortization expense, as appropriate.
	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 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. Some content suppliers offer financial incentives to support the launch of a channel and ongoing marketing support. When such financial incentives are received, we defer them within non-current liabilities in our consolidated balance sheets and recognize such amounts as a reduction of programming costs (which are a component of service costs in the consolidated statement of operations) over the carriage term of the programming contract.
	Recent Accounting Pronouncements
	In July 2012, the FASB issued Accounting Standards Update No. 2012-02 (“ASU 2012-02”) Testing Indefinite-Lived Intangible Assets for Impairment. ASU 2012-02 expands the guidance in ASU 2011-08 to include indefinite-lived intangible assets other than goodwill. We adopted this ASU on December 1, 2012. ASU 2012-02 did not have a material impact on our financial statements or related disclosures.
	In December 2013, the FASB issued Accounting Standards Update No. 2013-12 (“ASU 2013-12”) Definition of a Public Business Entity. ASU 2013-12 defines a public business entity which will be used in considering the scope of new financial guidance and will identify whether the guidance does or does not apply to public business entities. The Accounting Standards Codification includes multiple definitions of the terms nonpublic entity and public entity. ASU 2013-12 states that an entity that is required by the SEC to file or furnish financial statements with the SEC, or does file or furnish financial statements with the SEC, is considered a public business entity. There is no actual effective date for ASU 2013-12. We adopted ASU 2013-12 as of December 31, 2013. We are deemed to be a public entity per this guidance.

	As of December 31, 2013 and 2012, respectively, our financial assets and liabilities consisted of interest rate exchange agreements.
	The tables below set forth our financial assets and liabilities measured at fair value, on a recurring basis, using a market-based approach at December 31, 2013. These assets and liabilities have been categorized according to the three-level fair value hierarchy established by ASC 820, which prioritizes the inputs used in measuring fair value, as follows:
	•		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.
	As of December 31, 2013, our interest rate exchange agreement liabilities, net, were valued at $34.3 million using Level 2 inputs, as follows (dollars in thousands):

	The fair value of our interest rate swaps is the estimated amount that we would receive or pay to terminate such agreements, taking into account market interest rates and the remaining time to maturities. As of December 31, 2013, based upon mark-to-market valuation, we recorded on our consolidated balance sheet, an accumulated current liability in accounts payable, accrued expenses and other current liabilities of $24.5 million and an accumulated long-term liability in other non-current liabilities of $9.8 million. As of December 31, 2012, based upon mark-to-market valuation, we recorded on our consolidated balance sheet, an accumulated current liability in accounts payable, accrued expenses and other current liabilities of $24.2 million and an accumulated long-term liability in other non-current liabilities of $32.9 million. As a result of the mark-to-market valuations on these interest rate swaps, we recorded a net gain on derivatives of $22.8 million and $6.2 million for the years ended December 31, 2013 and 2012, respectively, and a net loss on derivatives of $17.9 million for the year ended December 31, 2011.

	Total long-term debt		$	1,892,000	$	1,943,000
	Bank Credit Facility
	As of December 31, 2013, we maintained a $1.755 billion bank credit facility (the “credit facility”), comprising $1.539 billion of outstanding term loans and $216.0 million of revolving credit commitments. 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.
	On August 2, 2013, we entered into an amended and restated credit agreement (the “credit agreement”) governing the credit facility that replaced the prior credit agreement in its entirety. The credit agreement included certain amendments to a number of terms and conditions, including covenants relating to restricted payments, excess cash recapture, asset sales and acquisitions.
	As of December 31, 2013, the credit agreement required us to maintain a total leverage ratio (as defined in the credit agreement) of no more than 5.5 to 1.0 and an interest coverage ratio (as defined in the credit agreement) of no less than 1.75 to 1.0. The total leverage ratio covenant will be reduced to 5.0 to 1.0 commencing on April 1, 2014. For all periods through December 31, 2013, we were in compliance with all covenants under the credit agreement, including a total leverage ratio of 4.2 to 1.0 and an interest coverage ratio of 3.1 to 1.0, respectively.
	Revolving Credit Commitments
	On November 10, 2011, we entered into an incremental facility agreement for $216.0 million of new revolving credit commitments, which expire on December 31, 2016 (or July 31, 2014 if Term Loan D under the credit facility has not been repaid or refinanced prior to that date).
	Interest on our revolving credit commitments is payable at a floating rate equal to, at our discretion, the London Interbank Offered Rate (“LIBOR”) plus a margin ranging from 2.25% to 3.00%, or the Prime rate plus a margin ranging from 1.25% to 2.00%, with the applicable margin determined by certain financial ratios pursuant to the credit agreement. Commitment fees on the unused portion of revolving credit commitments are payable at a rate of 0.50% or 0.63%, determined by certain financial ratios pursuant to the credit agreement.
	As of December 31, 2013, we had $135.6 million of unused revolving credit commitments, all of which were able to be borrowed and used for general corporate purposes, after giving effect to $69.5 million of outstanding loans and $10.9 million of letters of credit issued to various parties as collateral.
	Term Loan D
	In May 2006, we entered into an incremental facility agreement that provided for a term loan in the original principal amount of $800.0 million (“Term Loan D”). Term Loan D matures on January 31, 2015 and, since March 31, 2007, has been subject to quarterly reductions of $2.0 million, representing 0.25% of the original principal amount, with a final payment of $736.0 million at maturity representing 92.00% of the original principal amount. As of December 31, 2013, the outstanding balance under Term Loan D was $744.0 million.
	Interest on Term Loan D is payable at a floating rate equal to, at our discretion, LIBOR plus a margin of 1.50% or 1.75%, or the Prime Rate plus a margin of 0.50% or 0.75%, with the applicable margin determined by certain financial ratios pursuant to the credit agreement.
	Repayment of the remaining outstanding principal amount of Term Loan D on, or prior to, maturity depends on our ability to access the debt markets to refinance such loans. If we are unable to obtain financing to refinance the remaining principal amount outstanding under Term Loan D, we would need to take other actions, including selling assets or seeking strategic investments from third parties, and deferring capital expenditures or other discretionary uses of cash. A failure to complete such scheduled debt repayment would permit the lenders in the credit facility to accelerate all obligations thereunder, and would also trigger a cross-default under the indenture governing our senior notes (the “indenture”), which could result in most, or all, of our long-term debt becoming due and payable.
	Term Loan G
	In August 2012, we entered into an amended and restated credit agreement that, among other things, provided for a new term loan in the principal amount of $200.0 million (“Term Loan G”). Term Loan G matures on January 20, 2020 and, since December 31, 2013, has been subject to quarterly reductions of $0.5 million, representing 0.25% of the original principal amount, with a final payment at maturity of $185.5 million, representing 92.75% of the original principal amount. As of December 31, 2013, the outstanding balance under Term Loan G was $197.5 million.
	Interest on Term Loan G is payable at a floating rate equal to, at our discretion, LIBOR plus a margin of 3.00% (subject to a minimum LIBOR of 1.00%), or the Prime Rate plus a margin of 2.00% (subject to a minimum Prime Rate of 2.00%).
	Term Loan H
	On May 29, 2013, we entered into an incremental facility agreement that provided for a new term loan in the principal amount of $600.0 million (“Term Loan H”), and borrowed the full amount of such term loan on the same date. Net proceeds from Term Loan H of $594.8 million, after giving effect to financing costs of $5.2 million, were used to repay all outstanding borrowings under Term Loan F under the credit facility, to pay related fees and expenses, and for general corporate purposes. Term Loan H matures on January 29, 2021 and, since September 30, 2013, has been subject to quarterly reductions 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. As of December 31, 2013, the outstanding balance under Term Loan H was $597.0 million.
	Interest on Term Loan H is payable 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%).
	Interest Rate Exchange Agreements
	We use interest rate exchange agreements (which we refer to as “interest rate swaps”) with various banks to fix the variable portion of borrowings under the credit facility. We believe this reduces the potential volatility in our interest expense that would otherwise 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 basis as of, and for the years ended, December 31, 2013, 2012 and 2011. As of December 31, 2013:
		•		We had current interest rate swaps which fixed the variable portion of $800 million of borrowings under the credit facility at a rate of 3.3%, of which $600 million and $200 million during the years ending December 31, 2014 and 2015, respectively.
		•		We had forward-starting interest rate swaps which will fix the variable portion of $300 million of borrowings under the credit facility at a rate of 2.6% for one year commencing December 31, 2014.
	As of December 31, 2013, the average interest rate on outstanding borrowings under the credit facility, including the effect of our interest rate swaps, was 4.2%.
	Senior Notes
	As of December 31, 2013, we had $300.0 million of outstanding principal amount under our 6 3⁄8% senior notes due April 2023 (the “6 3⁄8% Notes”). On August 28, 2012, we issued the 6 3⁄8% Notes in the aggregate principal amount of $300.0 million. Together with borrowings under the credit facility, the net proceeds from the 6 3⁄8% Notes of $294.5 million were used to repay certain existing senior notes.
	Our senior notes are unsecured obligations, and the indenture limits the incurrence of additional indebtedness based upon a maximum debt to operating cash flow ratio (as defined in the indenture) of 8.5 to 1.0. As of December 31, 2013, we were in compliance with all of the covenants under the indenture, including a debt to operating cash flow ratio of 5.2 to 1.0.
	Other Assets
	Other assets, net, primarily include financing costs and original issue discount incurred to raise debt, which are deferred and amortized as interest expense over the expected term of such financings. Original issue discount, as recorded in other assets, net, was $8.2 million and $10.0 million as of December 31, 2013 and 2012, respectively.
	Debt Ratings
	MCC’s corporate credit rating is B1 by Moody’s, with a positive outlook, and BB- by Standard and Poor’s (“S&P”), with a stable outlook. Our senior unsecured credit rating is B3 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 indenture that are based on changes in our credit rating assigned by any rating agency.
	Fair Value and Debt Maturities
	As of December 31, 2013 and 2012, 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 (dollars in thousands):

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. 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 share-based compensation. 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, HSD, phone and business services revenues are recognized when the services are provided to our customers. 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 fees collected from customers are recognized as deferred revenue until the earnings process is complete. Under the terms of our franchise agreements, we are required to pay local franchising authorities up to 5% of our gross revenues derived from providing cable services. We normally pass these fees through to our customers. Because franchise fees are our obligation, we present them on a gross basis with a corresponding expense. Franchise fees reported on a gross basis amounted to approximately $23.9 million, $24.7 million and $24.9 million for the years ended December 31, 2013, 2012 and 2011, respectively. Franchise fees are reported in their respective revenue categories and included in selling, general and administrative expenses.
Restricted cash and cash equivalents	'
	Restricted cash and cash equivalents
	Restricted cash and cash equivalents represent funds pledged to insurance carriers as security under a master pledge and security agreement. Pledged funds are invested in short-term, highly liquid investments. We retained ownership of the pledged funds, and under the terms of the pledge and security agreement, we can withdraw any of the funds, with the restrictions removed from such funds, provided comparable substitute collateral is pledged to the insurance carriers. During the year ended December 31, 2011, we redeemed $6.2 million of restricted cash and cash equivalents, representing the entire outstanding balance.
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		Life of respective lease
	Cable systems and equipment and customer devices		5 to 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 the 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 also Note 3.
Capitalized Software Costs	'
	Capitalized Software Costs
	We account for internal-use software development and related costs in accordance with ASC 350-40-Intangibles-Goodwill and Other: Internal-Use Software. Software development and other related costs consist of external and internal costs incurred in the application development stage to purchase and implement the software that will be used in our telephony business. Costs incurred in the development of application and infrastructure of the software is capitalized and will be amortized over our respective estimated useful life of 5 years. During the years ended December 31, 2013 and 2012, we capitalized approximately $0.2 million and $1.0 million, respectively of software development costs. Capitalized software had a net book value of $16.3 million and $16.1 million as of December 31, 2013 and 2012, respectively.
Marketing and Promotional Costs	'
	Marketing and Promotional Costs
	Marketing and promotional costs are expensed as incurred and were $22.6 million, $22.9 million and $20.9 million for the years ended December 31, 2013, 2012 and 2011, respectively.
Intangible Assets	'
	Intangible Assets
	Our cable systems operate under non-exclusive cable franchises, or franchise rights, granted by state and local governmental authorities for varying lengths of time. We acquired these cable franchises through acquisitions of cable systems and were accounted for using the purchase method of accounting. As of December 31, 2013, we held 494 franchises in areas located throughout the United States. The value of a franchise is derived from the economic benefits we receive from the right to solicit new customers and to market new products and services, such as digital video, HSD and phone, in a specific market territory. We concluded that our franchise rights have an indefinite useful life since, among other things, there are no legal, regulatory, contractual, competitive, economic or other factors limiting the period over which these franchise rights contribute to our revenues and cash flows. Goodwill is the excess of the acquisition cost of an acquired entity over the fair value of the identifiable net assets acquired. In accordance with ASC No. 350 — Intangibles — Goodwill and Other (“ASC 350”), we do not amortize franchise rights and goodwill. Instead, such assets are tested annually for impairment or more frequently if impairment indicators arise.
	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 Excess Earnings DCF methodology. Significant impairment in value resulting in impairment charges may result if the estimates and assumptions used in the fair value determination change in the future. Such impairments, if recognized, could potentially be material.
	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 LLC. Comprising cable system clusters across several states, Mediacom Broadband LLC 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 process. The first step compares the fair value of a reporting unit with our carrying amount, including goodwill. If the fair value of the reporting unit exceeds our carrying amount, goodwill of the reporting unit is considered not impaired and the second step is unnecessary. If the carrying amount of a reporting unit exceeds our fair value, the second step is performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of the reporting unit’s goodwill, calculated using the residual method, with the carrying amount of that goodwill. If the carrying amount of the goodwill exceeds the implied fair value, the excess is recognized as an impairment loss.
	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, 2013, 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), as of October 1, 2013, we have evaluated whether there are any adverse qualitative factors surrounding our Mediacom Broadband reporting unit (which has a negative carrying value) indicating that a goodwill impairment may exist. We do not believe that it is “more likely than not” that a goodwill impairment exists. As such, we have not performed Step 2 of the goodwill impairment test.
	The following table details changes in the carrying value of goodwill for the years ended December 31, 2013 and 2012, respectively, (dollars in thousands):
	Balance - December 31, 2011	$	195,945

Segment Reporting	'
	Segment Reporting
	ASC 280 — Segment Reporting (“ASC 280”), requires the disclosure of factors used to identify an enterprise’s reportable segments. Our operations are organized and managed on the basis of cable system clusters within our service area. Each cable system cluster derives revenues from the delivery of similar products and services to a customer base that is also similar. Each cable system cluster deploys similar technology to deliver our products and services, operates within a similar regulatory environment and has similar economic characteristics. Management evaluated the criteria for aggregation under ASC 280 and believes that we meet each of the respective criteria set forth. Accordingly, management has identified broadband services as our one reportable segment.
Accounting for Derivative Instruments	'
	Accounting for Derivative Instruments
	We account for derivative instruments in accordance with ASC 815 — Derivatives and Hedging (“ASC 815”). These pronouncements require that all derivative instruments be recognized on the balance sheet at fair value. We enter into interest rate swaps to fix the interest rate on a portion of our variable interest rate debt to reduce the potential volatility in our interest expense that would otherwise result from changes in market interest rates. Our derivative instruments are recorded at fair value and are included in other current assets, other assets and other liabilities of our consolidated balance sheet. Our accounting policies for these instruments are based on whether they meet our criteria for designation as hedging transactions, which include the instrument’s effectiveness, risk reduction and, in most cases, a one-to-one matching of the derivative instrument to our underlying transaction. Gains and losses from changes in fair values of derivatives that are not designated as hedges for accounting purposes are recognized in the consolidated statement of operations. We have no derivative financial instruments designated as hedges. Therefore, changes in fair value for the respective periods were recognized in the consolidated statement of operations.
Accounting for Asset Retirement	'
	Accounting for Asset Retirement
	We adopted ASC 410 — Asset Retirement Obligations (“ASC 410”), on January 1, 2003. ASC 410 addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. We reviewed our asset retirement obligations to determine the fair value of such liabilities and if a reasonable estimate of fair value could be made. This entailed the review of leases covering tangible long-lived assets as well as our rights-of-way under franchise agreements. Certain of our franchise agreements and leases contain provisions that require restoration or removal of equipment if the franchises or leases are not renewed. Based on historical experience, we expect to renew our franchise or lease agreements. In the unlikely event that any franchise or lease agreement is not expected to be renewed, we would record an estimated liability. However, in determining the fair value of our asset retirement obligation under our franchise agreements, consideration will be given to the Cable Communications Policy Act of 1984, which generally entitles the cable operator to the “fair market value” for the cable system covered by a franchise, if renewal is denied and the franchising authority acquires ownership of the cable system or effects a transfer of the cable system to another person. Changes in these assumptions based on future information could result in adjustments to estimated liabilities.
	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 December 31, 2013 and 2012, 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 (“ASC 360”), we periodically evaluate the recoverability and estimated lives of our long-lived assets, including property and equipment and intangible assets subject to amortization, whenever events or changes in circumstances indicate that the carrying amount may not be recoverable or the useful life has changed. The measurement for such impairment loss is based on the fair value of the asset, typically based upon the future cash flows discounted at a rate commensurate with the risk involved. Unless presented separately, the loss is included as a component of either depreciation expense or amortization expense, as appropriate.
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 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. Some content suppliers offer financial incentives to support the launch of a channel and ongoing marketing support. When such financial incentives are received, we defer them within non-current liabilities in our consolidated balance sheets and recognize such amounts as a reduction of programming costs (which are a component of service costs in the consolidated statement of operations) over the carriage term of the programming contract.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In July 2012, the FASB issued Accounting Standards Update No. 2012-02 (“ASU 2012-02”) Testing Indefinite-Lived Intangible Assets for Impairment. ASU 2012-02 expands the guidance in ASU 2011-08 to include indefinite-lived intangible assets other than goodwill. We adopted this ASU on December 1, 2012. ASU 2012-02 did not have a material impact on our financial statements or related disclosures.
	In December 2013, the FASB issued Accounting Standards Update No. 2013-12 (“ASU 2013-12”) Definition of a Public Business Entity. ASU 2013-12 defines a public business entity which will be used in considering the scope of new financial guidance and will identify whether the guidance does or does not apply to public business entities. The Accounting Standards Codification includes multiple definitions of the terms nonpublic entity and public entity. ASU 2013-12 states that an entity that is required by the SEC to file or furnish financial statements with the SEC, or does file or furnish financial statements with the SEC, is considered a public business entity. There is no actual effective date for ASU 2013-12. We adopted ASU 2013-12 as of December 31, 2013. We are deemed to be a public entity per this guidance.
