Organization	'
	1. ORGANIZATION
	Basis of Preparation of Unaudited Consolidated Financial Statements
	Mediacom LLC (“Mediacom LLC” and collectively with its subsidiaries, “we,” “our” or “us”) is a New York 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 Broadband LLC, a Delaware limited liability company wholly-owned by MCC. As limited liability companies, we and Mediacom Broadband LLC are not subject to income taxes and, as such, are included in the consolidated federal and state income tax returns of MCC, which is 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 have prepared these unaudited consolidated financial statements in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of management, such statements include all adjustments, consisting of normal recurring accruals and adjustments, necessary for a fair presentation of our consolidated results of operations and financial position for the interim periods presented. The accounting policies followed during such interim periods reported are in conformity with generally accepted accounting principles in the United States of America and are consistent with those applied during annual periods. For a summary of our accounting policies and other information, refer to our Annual Report on Form 10-K for the year ended December 31, 2012. The results of operations for the interim periods are not necessarily indicative of the results that might be expected for future interim periods or for the full year ending December 31, 2013.
	Mediacom Capital Corporation (“Mediacom Capital”), a New York corporation wholly-owned by us, co-issued, jointly and severally with us, public debt securities. Mediacom Capital 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.
	Franchise fees imposed by local governmental authorities are collected on a monthly basis from our customers and are periodically remitted to the local governmental authorities. Because franchise fees are our obligation, we present them on a gross basis with a corresponding operating expense. Franchise fees reported on a gross basis amounted to approximately $3.1 million and $3.0 million for the three months ended September 30, 2013 and 2012, respectively, and approximately $9.2 million for each of the nine months ended September 30, 2013 and 2012.
	Reclassifications
	Certain reclassifications have been made to prior year amounts to conform to the current year presentation.

	2. RECENT ACCOUNTING PRONOUNCEMENTS
	In July 2012, the Financial Accounting Standards Board (“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 Accountings Standard Update No. 2011-08 (“ASU 2011-08”) Intangibles – Goodwill and Other 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 January 2013, the FASB issued Accounting Standards Update No. 2013-01 (“ASU 2013-01”), Balance Sheet (Topic 210). ASU 2013-01 contains amendments to balance sheet guidance. The amendments clarify the scope of ASU 2011-11 and apply to derivatives accounted for in accordance with Topic 815, Derivatives and Hedging. An entity is required to apply the amendments for fiscal years beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the required disclosures retrospectively for all comparative periods presented. The effective date is the same as the effective date of ASU 2011-11. We adopted ASU 2013-01 on January 1, 2013. ASU 2013-01 did not have a material impact on our financial statements or related disclosures.
	In February 2013, the FASB issued Accounting Standards Update No. 2013-02 (“ASU 2013-02”), Comprehensive Income (Topic 220). This ASU contains amendments to the guidance surrounding accumulated other comprehensive income. The amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. For public entities, ASU 2013-02 was effective prospectively for reporting periods beginning after December 15, 2012. We adopted ASU 2013-02 on January 1, 2013. ASU 2013-02 did not have an impact on our financial statements or related disclosures.

Fair Value	'
	3. 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 at September 30, 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 September 30, 2013, our interest rate exchange agreement liabilities, net, were valued at $34.1 million using Level 2 inputs, as follows (dollars in thousands):


			Fair Value as of September 30, 2013

	Interest rate exchange agreements—liabilities, net		$	—	$	34,053	$	—	$	34,053

	As of December 31, 2012, our interest rate exchange agreement liabilities, net, were valued at $48.0 million using Level 2 inputs, as follows (dollars in thousands):


			Fair Value as of December 31, 2012

	Interest rate exchange agreements—liabilities, net		$	—	$	48,015	$	—	$	48,015

	The fair value of our interest rate exchange agreements is the estimated amount that we would receive or pay to terminate such agreements, taking into account projected interest rates, based on quoted LIBOR futures, and the remaining time to maturities. While our interest rate exchange agreements 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. Based upon the mark-to-market valuation of these interest rate exchange agreements, all of our interest rate exchange agreements were in a liability position as of September 30, 2013 and December 31, 2012, and therefore no assets were recorded on our consolidated balance sheets. As of both September 30, 2013 and December 31, 2012, based on such mark-to-market valuations, we recorded an accumulated current liability in “accounts payable, accrued expenses and other current liabilities” of $19.3 million and, as of the same dates, an accumulated long-term liability in “other non-current liabilities” of $14.8 million and $28.7 million, respectively.
	As a result of the mark-to-market valuations on these interest rate exchange agreements, we recorded a net gain on derivatives of $2.8 million and a net loss on derivatives of $0.1 million for the three months ended September 30, 2013 and 2012, respectively, and a net gain on derivatives of $14.0 million and $0.4 million for the nine months ended September 30, 2013 and 2012, respectively.

	Less: current portion			9,000		9,000

	Total long-term debt		$	1,488,000	$	1,513,000

	Bank Credit Facility
	As of September 30, 2013, we maintained a $1.073 billion bank credit facility (the “credit facility”), comprising:

		•		$225.2 million of revolving credit commitments, which expire on December 31, 2014; if we do not refinance the existing Term Loan C under the credit facility prior to June 30, 2014, our existing revolving credit commitments will expire, and any amounts outstanding would then become due on such date;

		•		$606.1 million of outstanding Term Loan C borrowings, which mature on January 31, 2015; and

		•		$241.9 million of outstanding Term Loan E borrowings, which mature on October 23, 2017.

	As of September 30, 2013, we had $166.8 million of unused revolving credit commitments, all of which were available to be borrowed and used for general corporate purposes, after giving effect to $49.0 million of outstanding loans and $9.4 million of letters of credit issued thereunder to various parties as collateral.
	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 September 30, 2013, the credit agreement governing the credit facility (the “credit agreement”) required us 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. As of September 30, 2013, we were in compliance with all covenants under the credit agreement, including a total leverage ratio of 3.1 to 1.0 and an interest coverage ratio of 2.9 to 1.0.
	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 three and nine months ended, September 30, 2013 and 2012. As of September 30, 2013:

		•		We had current interest rate swaps that fixed the variable portion of $700 million of borrowings under the credit facility at a rate of 3.0%, of which $400 million and $300 million expire during the years ending December 31, 2014 and 2015, respectively; and

		•		We had forward-starting interest rate swaps that will fix the variable portion of $200 million of borrowings under the credit facility at a rate of 3.0% for one year commencing December 2014.
	As of September 30, 2013, the weighted average interest rate on outstanding borrowings under the credit facility, including the effect of our interest rate swaps, was 4.6%.
	Senior Notes
	As of September 30, 2013, we had $600 million of outstanding senior notes, comprising $350 million of 91/8% senior notes due August 2019 and $250 million of 71/4% senior notes due February 2022. Our senior notes are unsecured obligations, and the indenture governing our senior notes (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 September 30, 2013, we were in compliance with all covenants under the indenture, including a debt to operating cash flow ratio of 5.3 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 $5.6 million and $6.4 million as of September 30, 2013 and December 31, 2012, respectively.
	Debt Ratings
	MCC’s corporate credit rating is B1, with a stable outlook, by Moody’s, and B+, with a positive outlook, by Standard and Poor’s. Our senior unsecured credit rating is B3, with a stable outlook, by Moody’s, and B-, with a positive outlook, by Standard and Poor’s.
	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
	As of September 30, 2013 and December 31, 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):


			September 30, 2013		December 31, 2012
	9 1⁄8% senior notes due 2019		$	384,125	$	388,719
	7 1⁄4% senior notes due 2022			262,500		271,250

	11. GOODWILL AND OTHER INTANGIBLE ASSETS
	In accordance with ASC 350 – Intangibles – Goodwill and Other (“ASC 350”), the amortization of goodwill and indefinite-lived intangible assets is prohibited and requires such assets to be tested annually for impairment, or more frequently if impairment indicators arise. We have determined that our cable franchise rights and goodwill are indefinite-lived assets and therefore not amortizable.
	We have evaluated the qualitative factors surrounding our Mediacom LLC reporting unit as of October 1, 2012, which has negative equity carrying value. 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 economic conditions currently affecting the U.S. economy and the long-term impact on the fundamentals of our business may have a negative impact on the fair values of the assets in our reporting units. This may result in the recognition of an impairment loss in the future.
	Because we believe there has not been a meaningful change in the long-term fundamentals of our business during the first nine months of 2013, we have determined that there has been no triggering event under ASC 350 and, as such, no interim impairment test was required as of September 30, 2013.

Accounting Changes And Error Corrections [Abstract]	'
Basis of Preparation of Unaudited Consolidated Financial Statements	'
	Basis of Preparation of Unaudited Consolidated Financial Statements
	Mediacom LLC (“Mediacom LLC” and collectively with its subsidiaries, “we,” “our” or “us”) is a New York 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 Broadband LLC, a Delaware limited liability company wholly-owned by MCC. As limited liability companies, we and Mediacom Broadband LLC are not subject to income taxes and, as such, are included in the consolidated federal and state income tax returns of MCC, which is 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 have prepared these unaudited consolidated financial statements in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of management, such statements include all adjustments, consisting of normal recurring accruals and adjustments, necessary for a fair presentation of our consolidated results of operations and financial position for the interim periods presented. The accounting policies followed during such interim periods reported are in conformity with generally accepted accounting principles in the United States of America and are consistent with those applied during annual periods. For a summary of our accounting policies and other information, refer to our Annual Report on Form 10-K for the year ended December 31, 2012. The results of operations for the interim periods are not necessarily indicative of the results that might be expected for future interim periods or for the full year ending December 31, 2013.
	Mediacom Capital Corporation (“Mediacom Capital”), a New York corporation wholly-owned by us, co-issued, jointly and severally with us, public debt securities. Mediacom Capital 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.
	Franchise fees imposed by local governmental authorities are collected on a monthly basis from our customers and are periodically remitted to the local governmental authorities. Because franchise fees are our obligation, we present them on a gross basis with a corresponding operating expense. Franchise fees reported on a gross basis amounted to approximately $3.1 million and $3.0 million for the three months ended September 30, 2013 and 2012, respectively, and approximately $9.2 million for each of the nine months ended September 30, 2013 and 2012.

Testing Indefinite-Lived Intangible Assets for Impairment	'
Testing Indefinite-Lived Intangible Assets for Impairment	In July 2012, the Financial Accounting Standards Board (“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 Accountings Standard Update No. 2011-08 (“ASU 2011-08”) Intangibles – Goodwill and Other 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.
Balance Sheet	'
Balance Sheet	In January 2013, the FASB issued Accounting Standards Update No. 2013-01 (“ASU 2013-01”), Balance Sheet (Topic 210). ASU 2013-01 contains amendments to balance sheet guidance. The amendments clarify the scope of ASU 2011-11 and apply to derivatives accounted for in accordance with Topic 815, Derivatives and Hedging. An entity is required to apply the amendments for fiscal years beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the required disclosures retrospectively for all comparative periods presented. The effective date is the same as the effective date of ASU 2011-11. We adopted ASU 2013-01 on January 1, 2013. ASU 2013-01 did not have a material impact on our financial statements or related disclosures.
Comprehensive Income	'
Comprehensive Income	In February 2013, the FASB issued Accounting Standards Update No. 2013-02 (“ASU 2013-02”), Comprehensive Income (Topic 220). This ASU contains amendments to the guidance surrounding accumulated other comprehensive income. The amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. For public entities, ASU 2013-02 was effective prospectively for reporting periods beginning after December 15, 2012. We adopted ASU 2013-02 on January 1, 2013. ASU 2013-02 did not have an impact on our financial statements or related disclosures.
