Organization [Abstract]
ORGANIZATION	1. ORGANIZATION *Basis of Preparation of Unaudited Consolidated Financial Statements* Mediacom Broadband LLC (“Mediacom Broadband,” and collectively with its subsidiaries, “we,” “our” or “us”), a Delaware limited liability company wholly-owned by Mediacom Communications Corporation (“MCC”), is involved in the acquisition and operation of cable systems serving smaller cities and towns in the United States. 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, 2010. 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, 2010. Mediacom Broadband Corporation (“Broadband Corporation”), a Delaware corporation wholly-owned by us, co-issued, jointly and severally with us, public debt securities. 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. 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 $6.3 million for each of the three months ended June 30, 2011 and 2010, and approximately $12.6 million for each of the six months ended June 30, 2011 and 2010. 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 retain 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. Reclassifications Certain reclassifications have been made to prior year amounts to conform to the current year presentation.

Recently Issued Accounting Pronouncements [Abstract]
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS	2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In December 2010, FASB issued Accounting Standards Update 2010-28 (“ASU 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 amendments to ASC 350 — Intangibles—Goodwill and Other in ASU 2010-28 affect all entities that have recognized goodwill and have one or more reporting units whose carrying amount for purposes of performing Step 1 of the goodwill impairment test is zero or negative. The amendments modify Step 1 so that for those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors are consistent with existing guidance, which requires that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. We adopted ASU 2010-28 as of January 1, 2011. The adoption of ASU 2010-28 did not have a material impact on our financial statements. In January 2010, the FASB issued Accounting Standards Update No. 2010-06 (“ASU 2010-06”), Improving Disclosures about Fair Value Measurements, which amends Accounting Standards Codification (“ASC”) No. 820 — Fair Value Measurements and Disclosures (“ASC 820”) to add new requirements for disclosures about transfers into and out of Levels 1 and 2 and separate disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements. The ASU also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value. The ASU is effective for the first reporting period (including interim periods) beginning after December 15, 2009, except for the requirement to provide the Level 3 activity of purchases, sales, issuances, and settlements on a gross basis, which will be effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. Early adoption is permitted. The adoption of this ASU did not have a material impact on our financial statements or related disclosures. In May 2011, the FASB issued Accounting Standards Update No. 2011-04 (“ASU 2011-04”), Fair Value Measurement (Topic 820) - Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, which provides a converged framework for fair value measurements and related disclosures between generally accepted accounting principles in the U.S. and International Financial Reporting Standards. ASU 2011-04 amends the fair value measurement and disclosure guidance in the following areas: (i) Highest-and-best use and the valuation-premise concepts for non-financial assets, (ii) application to financial assets and liabilities with offsetting positions in market or counterparty credit risk, (iii) premiums or discounts in fair value measurement, (iv) fair value measurements for amounts classified in equity; and, (v) other disclosure requirements particularly involving Level 3 inputs. This guidance will be effective for us as of January 1, 2012. We do not expect that ASU 2011-04 will have a material impact on our financial statements or related disclosures.

Fair Value [Abstract]

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 June 30, 2011. 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 June 30, 2011, our interest rate exchange agreement liabilities, net, were valued at $49.6 million using Level 2 inputs, as follows:


	Fair Value as of June 30, 2011

As of December 31, 2010, our interest rate exchange agreement liabilities, net, were valued at $45.4 million using Level 2 inputs, as follows:

Interest rate exchange agreements — liabilities, net	$	—	$	45,363	$	—	$	45,363

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 market interest rates and the remaining time to maturities. As of June 30, 2011, based upon mark-to-market valuation, we recorded on our consolidated balance sheet, a long-term asset of $0.8 million, an accumulated current liability of $20.8 million and an accumulated long-term liability of $29.5 million. As of December 31, 2010, based upon mark-to-market valuation, we recorded on our consolidated balance sheet, a long-term asset of $2.3 million, an accumulated current liability of $18.0 million and an accumulated long-term liability of $29.7 million. As a result of the mark-to-market valuations on these interest rate exchange agreements, we recorded a net loss on derivatives of $11.6 million and $14.6 million for the three months ended June 30, 2011 and 2010, respectively. As a result of the mark-to-market valuations on these interest rate exchange agreements, we recorded a net loss on derivatives of $4.2 million and $19.9 million for the six months ended June 30, 2011 and 2010, respectively.

Total long-term debt	$	2,020,600	$	1,851,000

Bank Credit Facility

As of June 30, 2011, we maintained a $1.788 billion bank credit facility (the “credit facility”), comprised of:

•		$430.3 million of revolving credit commitments, which expire on December 31, 2012;

•		$764.0 million of outstanding Term Loan D borrowings, which mature on January 31, 2015; and

•		$594.0 million of outstanding Term Loan F borrowings, which mature on October 23, 2017.

As of June 30, 2011, we had $244.1 million of unused revolving credit commitments, after giving effect to $176.6 million of outstanding loans and $9.6 million of letters of credit issued to various parties as collateral, all of which were unused and available to be borrowed and used for general corporate purposes.

The credit agreement governing the credit facility requires us to maintain a senior leverage ratio (as defined) of no more than 6.0 to 1.0. For all periods through June 30, 2011, we were in compliance with all of the covenants under the credit agreement and, as of June 30, 2011, our senior leverage ratio was 4.4 to 1.0.

Interest Rate Exchange Agreements

We use interest rate exchange agreements, or interest rate swaps, with various banks that fixes 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 six months ended June 30, 2011, and 2010. As of June 30, 2011:

•

We had current interest rate swaps which fix the variable portion of $700 million of borrowings under the credit facility at a rate of 3.2%. Our current interest rate swaps are scheduled to expire in the amounts of $100 million and $600 million during the years ending December 31, 2011 and 2012, respectively; and

•

We had forward-starting interest rate swaps which will fix the variable portion of $900 million of borrowings under the credit facility at a rate of 3.3%. Our forward-starting interest rate swaps are scheduled to commence in the amounts of $100 million, $700 million and $100 million during the years ending December 31, 2011, 2012 and 2014, respectively.

As of June 30, 2011, the average interest rate on outstanding borrowings under the credit facility, including the effect of our interest rate swaps was 4.3%, as compared to 5.0% as of the same date last year.

Senior Notes

As of June 30, 2011, we had $500.0 million of senior notes outstanding. The indenture governing our senior notes requires a total leverage ratio (as defined) of no more than 8.5 to 1.0. As of June 30, 2011, we were in compliance with all of the covenants under the indenture, and our total leverage ratio was 6.1 to 1.0.

Debt Ratings

Our future access to the debt markets and the terms and conditions we receive are influenced by our debt ratings. Our corporate credit ratings are B1, with a stable outlook, by Moody’s, and B+, with a stable outlook, by Standard and Poor’s. Any future downgrade to our credit ratings could result in higher interest rates on future debt issuance than we currently experience, or adversely impact our ability to raise additional funds.

There are no covenants, events of default, borrowing conditions or other terms in our credit agreement or senior note indenture that are based on changes in our credit rating assigned by any rating agency.

Fair Value

As of June 30, 2011, the fair values of our senior notes and outstanding debt under our credit facility are as follows (dollars in thousands):


8¹/2% senior notes due 2015	$	510,625

Going Private Transaction

On November 12, 2010, MCC entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among MCC, JMC Communications LLC (“JMC”) and Rocco B. Commisso, MCC’s founder, Chairman and Chief Executive Officer, who was also the sole member and manager of JMC, for the purpose of taking MCC private (the “Going Private Transaction”).

At a special meeting of stockholders on March 4, 2011, MCC’s stockholders voted to adopt the Merger Agreement. On the same date, JMC was merged with and into MCC, with MCC continuing as the surviving corporation, a private company that is wholly-owned by Mr. Commisso (the “Merger”).

As a result of the Merger, (i) each outstanding share of MCC’s common stock (other than shares held by Mr. Commisso and his affiliates) was converted into the right to receive promptly after the Merger $8.75 in cash and (ii) each vested option held by an employee of MCC (other than Mr. Commisso) and each vested option and each unvested option and restricted stock unit held by a non-employee director of MCC was converted into the right to receive promptly after the Merger a cash payment calculated in accordance with the terms of the Merger Agreement. In addition, each unvested option and restricted stock unit held by an employee of MCC (other than Mr. Commisso) was converted into the right to receive upon vesting a cash payment calculated in accordance with the terms of the Merger Agreement. As a result of the Merger, MCC terminated all of its share-based compensation plans including its employee stock purchase plan and other plans which granted stock options and restricted stock units.

The Going Private Transaction required funding of approximately $381.5 million, including related transaction expenses, and was funded, in part, by capital distributions to MCC from us, consisting of $200.0 million of borrowings under our revolving credit facility and $45.0 million of cash on hand. The balance was funded by Mediacom LLC, another wholly-owned subsidiary of MCC.

Deferred Compensation

For the three and six months ended June 30, 2011, we recorded $0.5 million and $0.9 million, respectively, of deferred compensation expense (formerly share-based compensation expense). This represents the recognition of expenses incurred (based upon terms of the Merger Agreement) for (i) the unvested stock options and restricted stock units under the former share-based compensation plans at their original grant-date fair value and (ii) adjustments to recognize the right to receive $8.75 in cash. In addition, this amount includes the recognition of new, cash-based deferred compensation awarded in 2011 which has vesting attributes similar to the former share-based awards.

Total share-based compensation for the three and six months ended June 30, 2010 (prior to the Going Private Transaction) was as follows (dollars in thousands):


	Three Months Ended		Six Months Ended

Under MCC’s former employee stock purchase plan, all employees were allowed to participate in the purchase of shares of MCC’s Class A common stock at a 15% discount on the date of the allocation. As a result of the Going Private Transaction, the employee stock purchase plan terminated in March 2011. The net employee proceeds were $0 and approximately $0.2 million for the three months ended June 30, 2011 and 2010, respectively. The net employee proceeds were approximately $0.3 million and $0.4 million for the six months ended June 30, 2011 and 2010, respectively.

Commitments and Contingencies [Abstract]
COMMITMENTS AND CONTINGENCIES	10. COMMITMENTS AND CONTINGENCIES *Legal Proceedings* Jim Knight v. Mediacom Communications Corp. A purported class action in the United States District Court for the Southern District of New York entitled Jim Knight v. Mediacom Communications Corp., in which MCC is named as the defendant, was filed on March 4, 2010. The complaint asserts that the potential class is comprised of all persons who purchased premium cable services from MCC and rented a cable box distributed by MCC. The plaintiff alleges that MCC improperly “ties” the rental of cable boxes to the provision of premium cable services in violation of Section 1 of the Sherman Antitrust Act. The plaintiff also alleges a claim for unjust enrichment and seeks injunctive relief and unspecified damages. MCC was served with the complaint on April 16, 2010. On August 8, 2011 Mr. Knight dismissed his claim with prejudice and the case was closed. Mediacom Communications Shareholders Litigation Between June 3, 2010 and June 10, 2010, three purported class actions lawsuits were filed against MCC and its individual directors, including Mr. Commisso, all in the Court of Chancery of the State of Delaware (which we refer to as the “Delaware Court”), under the captions Colleen Witmer v. Mediacom Communications Corporation, et al., J. Malcolm Gray v. Mediacom Communications Corporation, et al. and Haverhill Retirement System v. Mediacom Communications Corporation, et al. The lawsuits were subsequently consolidated for all purposes in the Delaware Court of Chancery under the caption In Re Mediacom Communications Corporation Shareholders Litigation. On January 4, 2011, a Second Verified Consolidated Amended Class Action Complaint was filed that alleged, among other things, that the defendant directors breached their fiduciary duties to the stockholders of MCC in connection with Mr. Commisso’s proposal to take MCC private, including among other things their fiduciary duty of disclosure, and that MCC, Mr. Commisso and JMC Communications LLC aided and abetted such breaches. The plaintiffs sought injunctive relief, rescission of the transaction or rescissory damages, and an accounting of all damages. On November 18, 2010, another purported class action lawsuit was filed against MCC and its individual directors, including Mr. Commisso, in the Supreme Court of the State of New York, Orange County, under the caption Wendy Kwait v. Mediacom Communications Corporation, et al. The lawsuit alleged, among other things, that the director defendants breached their fiduciary duties to the stockholders of MCC in connection with Mr. Commisso’s proposal to take MCC private and that MCC and Mr. Commisso aided and abetted such breaches. The plaintiffs sought injunctive relief, rescission of the transaction or rescissory damages. On November 29, 2010, another purported class action lawsuit was filed against MCC and its individual directors, including Mr. Commisso, in the United States District Court for the Southern District of New York, under the caption Thomas Turberg v. Mediacom Communications Corporation, et al. The lawsuit alleged, among other things, that the director defendants breached their fiduciary duties to the stockholders of MCC in connection with Mr. Commisso’s proposal to take MCC private and that MCC and JMC Communications LLC aided and abetted such breaches. The plaintiffs sought injunctive relief and damages. On December 10, 2010, another purported class action lawsuit was filed against MCC and its individual directors, including Mr. Commisso, in the United States District Court for the Southern District of New York, under the caption Ella Mae Pease v. Rocco Commisso, et al. The lawsuit alleged, among other things, that the director defendants breached their fiduciary duties to the stockholders of MCC in connection with Mr. Commisso’s proposal to take MCC private; that MCC, Mr. Commisso and JMC Communications LLC aided and abetted such breaches; and that the defendants violated Section 14(a) of the Exchange Act and Rule 14a-9 promulgated thereunder. The plaintiffs sought declaratory and injunctive relief, rescission of the transaction or rescissory damages, and an accounting of all damages, profits and special benefits. The director defendants, MCC, JMC Communications LLC and Mr. Commisso, as defendants in the foregoing actions, reached agreement with the plaintiffs in all of the foregoing actions providing for the settlement of the actions on the terms and subject to the conditions set forth in a settlement agreement (the “Agreement”), which terms included, but were not limited to, a settlement payment made by MCC on behalf of and for the benefit of the parties to the actions in the amount of $0.25 per share for each share of MCC common stock held by the plaintiff class as of March 4, 2011. The settlement payment to the plaintiff class was reduced by any attorneys’ fees and expenses awarded to plaintiffs’ counsel. On June 6, 2011, the Agreement was approved by the Delaware Court. All litigation related to the going private transaction has been dismissed with prejudice. As of July 25, 2011, all of the conditions to the Agreement had been satisfied. A settlement payment of $10.3 million was subsequently made, of which we funded $5.7 million through a capital distribution to MCC, with the remainder funded by Mediacom LLC. We are also involved in various other legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these other matters will not have a material adverse effect on our consolidated financial position, results of operations, cash flows or business.

Goodwill and Other Intangible Assets [Abstract]
GOODWILL AND OTHER INTANGIBLE ASSETS	11. GOODWILL AND OTHER INTANGIBLE ASSETS In accordance with ASC 350 — Intangibles — Goodwill and Other (“ASC 350”) (formerly SFAS No. 142, “Goodwill and Other Intangible Assets”), 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 directly assess the value of cable franchise rights for impairment under ASC 350 by utilizing a discounted cash flow methodology. In performing an impairment test in accordance with ASC 350, we make assumptions, such as future cash flow expectations, customer growth, competition, industry outlook, capital expenditures, and other future benefits related to cable franchise rights, which are consistent with the expectations of buyers and sellers of cable systems in determining fair value. If the determined fair value of our cable franchise rights is less than the carrying amount on the financial statements, an impairment charge would be recognized for the difference between the fair value and the carrying value of such assets. Goodwill impairment is determined 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 a 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. We have determined that we have one reporting unit for the purpose of applying ASC 350, Mediacom Broadband. Our most recently completed annual impairment test was conducted as of October 1, 2010, and we will be conducting our next annual impairment test as of October 1, 2011. In accordance with ASU 2010-28, we have evaluated the qualitative factors surrounding our Mediacom Broadband reporting unit with its 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 six months of 2011, we have determined that there has been no triggering event under ASC 350, and as such, no interim impairment test was required as of June 30, 2011.
