	1. ORGANIZATION
	Basis of Preparation of Unaudited Consolidated Financial Statements
	Mediacom Broadband LLC (“Mediacom Broadband,” and collectively with its subsidiaries, “we,” “our” or “us”) is a Delaware limited liability company wholly-owned by Mediacom Communications Corporation (“MCC”). MCC is involved in the acquisition and operation of cable systems serving smaller cities and towns in the United States, and its cable systems are owned and operated through our operating subsidiaries and those of Mediacom LLC, a New York limited liability company wholly-owned by MCC. As limited liability companies, we and Mediacom LLC are not subject to income taxes and, as such, are included in the consolidated federal and state income tax returns of MCC, a C corporation.
	Our principal operating subsidiaries conduct all of our consolidated operations and own substantially all of our consolidated assets. Our operating subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to make funds available to us.
	We 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, 2013. 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, 2014.
	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 $5.8 million and $6.0 million for the three months ended September 30, 2014 and 2013, respectively, and approximately $17.4 million and $18.0 million for the nine months ended September 30, 2014 and 2013, respectively.
	Reclassifications
	Certain reclassifications have been made to prior year amounts to conform to the current year presentation.

	2. RECENT ACCOUNTING PRONOUNCEMENTS
	In December 2013, the Financial Accounting Standards Board (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 to be used in considering the scope of new financial guidance and identifies whether the guidance does or does not apply to public business entities. The Accounting Standards Codification (“ASC”) 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 effective date for ASU 2013-12. We adopted ASU 2013-12 as of December 31, 2013. We are deemed to be a public entity according to this guidance.
	In May 2014, the FASB issued ASU No. 2014-09 (“ASU 2014-09”) – Revenue from Contracts with Customers. The guidance states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity should also disclose sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance supersedes most industry-specific guidance, including Statement of Financial Accounting Standards No. 51 – Financial Reporting by Cable Television Companies. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. We have not completed our evaluation of this new guidance to determine its impact on our financial statements, financial disclosures and our method of adoption.

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, 2014 and December 31, 2013. Our financial assets and liabilities, all of which represent interest rate exchange agreements (which we refer to as “interest rate swaps”) have been categorized according to the three-level fair value hierarchy established by ASC No. 820 — Fair Value Measurement, 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, 2014, our interest rate swap liabilities, net, were valued at $16.8 million using Level 2 inputs, as follows (dollars in thousands):


			Fair Value as of September 30, 2014
			Level 1		Level 2		Level 3		Total

	Interest rate exchange agreements		$	—	$	—	$	—	$	—

	Interest rate exchange agreements—liabilities, net		$	—	$	16,849	$	—	$	16,849

	As of December 31, 2013, our interest rate swap liabilities, net, were valued at $34.3 million using Level 2 inputs, as follows (dollars in thousands):


			Fair Value as of December 31, 2013
			Level 1		Level 2		Level 3		Total
	Assets
	Interest rate exchange agreements		$	—	$	—	$	—	$	—

	Interest rate exchange agreements—liabilities, net		$	—	$	34,275	$	—	$	34,275

	The fair value of our interest rate swaps represents the estimated amount that we would receive or pay to terminate such agreements, taking into account projected interest rates, based on quoted London Interbank Offered Rate (“LIBOR”) futures and the remaining time to maturity. While our interest rate swaps are subject to contractual terms that provide for the net settlement of transactions with counterparties, we do not offset assets and liabilities under these agreements for financial statement presentation purposes, and assets and liabilities are reported on a gross basis.
	All of our interest rate swaps were in a liability position as of each of September 30, 2014 and December 31, 2013, based upon their mark-to-market valuation, and therefore no assets were recorded on our consolidated balance sheets. As of September 30, 2014, we recorded a current liability in accounts payable, accrued expenses and other current liabilities of $14.7 million and a long-term liability in other non-current liabilities of $2.1 million. As of December 31, 2013, we recorded a current liability in accounts payable, accrued expenses and other current liabilities of $24.5 million and a long-term liability in other non-current liabilities of $9.8 million.
	As a result of the changes in the mark-to-market valuations on our interest rate swaps, we recorded a net gain on derivatives of $6.3 million and $3.9 million for the three months ended September 30, 2014 and 2013, respectively, and a net gain on derivatives of $17.4 million and $17.6 million for the nine months ended September 30, 2014 and 2013, respectively.

	2014 Financings
	On March 17, 2014, we issued 5 1⁄2% senior notes due April 2021 in the aggregate principal amount of $200.0 million (the “5 1⁄2% Notes”). The 5 1⁄2% Notes are unsecured obligations, and their indenture is substantially similar to the indenture governing our 6 3/8% senior notes due 2023 (the “6 3⁄8% Notes”). After giving effect to $3.8 million of financing costs, net proceeds from the 5 1⁄2% Notes of $196.2 million substantially funded a $200.0 million partial repayment of the existing Term Loan D under our bank credit facility (the “credit facility”). As a percentage of par value, the 5 1⁄2% Notes are redeemable at 102.750% commencing April 1, 2017, 101.375% commencing April 1, 2018 and at par value commencing April 1, 2019.
	On June 20, 2014, we entered into an amended and restated credit agreement (the “credit agreement”) under the credit facility that provided for new term loans in the amount of $250.0 million (“Term Loan I”) and $300.0 million (“Term Loan J” and, together with Term Loan I, the “new term loans”), and on the same date, borrowed the full amounts under the new term loans. The credit agreement replaced the previously existing credit agreement in its entirety and amended certain terms and conditions, including the ability to amend and extend existing term loans and to prepay existing term loans on a non-pro rata basis. After giving effect to $6.6 million of financing costs, net proceeds of $543.4 million from the new term loans were substantially used to fund the full repayment of the remaining $542.5 million balance under Term Loan D. As a result of the repayment of Term Loan D, we recorded in our consolidated statements of operations a loss on early extinguishment of $0.3 million for the nine months ended September 30, 2014, which represented the write-off of certain unamortized financing costs.
	Borrowings under Term Loan I bear interest at a floating rate or rates equal to, at our discretion, LIBOR plus a margin of 2.50%, or the Prime Rate (subject to a minimum as provided in the credit agreement) plus a margin of 1.50%. Term Loan I matures on June 30, 2017 and, since September 30, 2014, has been subject to quarterly principal reductions of $0.6 million, representing 0.25% of the original principal amount, with a final payment at maturity of $243.1 million, representing 97.25% of the original principal amount.
	Borrowings under Term Loan J bear interest at a floating rate or rates equal to, at our discretion, LIBOR plus a margin of 3.00%, subject to a minimum LIBOR of 0.75%, or the Prime Rate plus a margin of 2.00%, subject to a minimum Prime Rate of 1.75%. For any quarterly period ending on or after September 30, 2014 in which our operating subsidiaries’ total leverage ratio (as defined in the credit agreement) is 3.0 to 1.0 or below, the margin on LIBOR and Prime Rate borrowings will be reduced to 2.75% and 1.75%, respectively. Term Loan J matures on June 30, 2021 and, since September 30, 2014, has been subject to quarterly principal reductions of $0.8 million, representing 0.25% of the original principal amount, with a final payment at maturity of $279.8 million, representing 93.25% of the original principal amount.
	Bank Credit Facility
	As of September 30, 2014, we maintained a $1.553 billion credit facility, comprising:

		•		$216.0 million of revolving credit commitments, which expire on December 31, 2016;

		•		$196.0 million of outstanding borrowings under Term Loan G, which matures on January 20, 2020;

		•		$592.5 million of outstanding borrowings under Term Loan H, which matures on January 29, 2021;

		•		$249.4 million of outstanding borrowings under Term Loan I, which matures on June 30, 2017; and

		•		$299.3 million of outstanding borrowings under Term Loan J, which matures on June 30, 2021.

	As of September 30, 2014, we had $205.6 million of unused revolving credit commitments, all of which were available to be borrowed and used for general corporate purposes, after giving effect to no outstanding loans and $10.4 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, 2014, the credit agreement required our operating subsidiaries to maintain a total leverage ratio (as defined in the credit agreement) of no more than 5.0 to 1.0 and an interest coverage ratio (as defined in the credit agreement) of no less than 1.75 to 1.0. For all periods through September 30, 2014, our operating subsidiaries were in compliance with all covenants under the credit agreement.
	On October 10, 2014, we terminated our existing revolving credit commitments and entered into an incremental facility agreement under the credit agreement, which provided for $216.0 million of new revolving credit commitments, with such commitments scheduled to expire on October 10, 2019. On the same date as the new revolver became effective, the interest coverage ratio financial covenant was amended to increase the minimum from 1.75 to 1.0 to 2.0 to 1.0. See Note 12.
	Interest Rate Swaps
	We have entered into several interest rate swaps with various banks to fix the variable rate of borrowings to reduce the potential volatility in our interest expense that may result from changes in market interest rates. Our interest rate swaps have not been designated as hedges for accounting purposes, and have been accounted for on a mark-to-market basis as of, and for the three and nine months ended, September 30, 2014 and 2013.
	As of September 30, 2014, we had interest rate swaps that fixed the variable rate of $800 million of borrowings at a rate of 3.3%, of which $600 million and $200 million expire during December 2014 and 2015, respectively. As of the same date, we also had forward starting interest rate swaps that will fix the variable rate of $300 million of borrowings at a rate of 2.6% for a one year period commencing December 2014.
	As of September 30, 2014, the weighted average interest rate on outstanding borrowings under the credit facility, including the effect of our interest rate swaps, was 5.2%.
	Senior Notes
	As of September 30, 2014, we had $500 million of outstanding senior notes, comprising $200 million of 5 1⁄2% senior notes due April 2021 and $300 million of 6 3⁄8% senior notes due April 2023. Our senior notes are unsecured obligations, and the indentures governing our senior notes (the “indentures”) limit the incurrence of additional indebtedness based upon a maximum debt to operating cash flow ratio (as defined in the indentures) of 8.5 to 1.0. For all periods through September 30, 2014, we were in compliance with all covenants under the indentures.
	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 $9.1 million and $8.2 million as of September 30, 2014 and December 31, 2013, 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 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 indentures that are based on changes in our credit rating assigned by any rating agency.

	Fair Value
	As of September 30, 2014 and December 31, 2013, 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,		December 31,
			2014		2013
	5 1⁄2% senior notes due 2021		$	198,750	$	—
	6 3⁄8% senior notes due 2023			307,500		308,250

	Total senior notes		$	506,250	$	308,250

	Bank credit facility		$	1,310,967	$	1,602,472

	11. GOODWILL AND OTHER INTANGIBLE ASSETS
	In accordance with the FASB’s Accounting Standards Codification No. 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 last evaluated the qualitative factors surrounding our Mediacom Broadband reporting unit as of October 1, 2013, and did not believe that it was “more likely than not” that a goodwill impairment existed at that time. As such, we did not perform Step 2 of the goodwill impairment test.

	Because we believe there has not been a meaningful change in the long-term fundamentals of our business during the first nine months of 2014, we determined that there has been no triggering event under ASC 350 and, as such, no interim impairment test was required as of September 30, 2014.

	12. SUBSEQUENT EVENTS
	On October 10, 2014, we terminated our existing $216.0 million of revolving credit commitments and entered into an incremental facility agreement under the credit agreement that provided for $216.0 million of new revolving credit commitments (the “new revolver”). The new revolver expires on the earliest of: (i) October 10, 2019; (ii) 91 days prior to the final maturity of any term loan under the credit facility if $200.0 million or more remains outstanding under such term loan on that date; or (iii) six months prior to the scheduled maturity date of any affiliated subordinated indebtedness that is then outstanding.
	Borrowings under the new revolver bear interest at a floating rate equal to, at our discretion, LIBOR plus a margin ranging from 2.00% to 2.75%, or the Prime Rate (subject to a minimum as provided in the credit agreement) plus a margin ranging from 1.00% to 1.75%. Commitment fees on the unused portion of the new revolver are payable at a rate of 0.375% or 0.50%. The applicable margin on outstanding borrowings under the new revolver and commitment fees charged on the unused portion of the new revolver are determined by certain financial ratios pursuant to the credit agreement.
	On the same date as the new revolver became effective, the interest coverage ratio financial covenant was amended to increase the minimum from 1.75 to 1.0 to 2.0 to 1.0.

	Basis of Preparation of Unaudited Consolidated Financial Statements
	Mediacom Broadband LLC (“Mediacom Broadband,” and collectively with its subsidiaries, “we,” “our” or “us”) is a Delaware limited liability company wholly-owned by Mediacom Communications Corporation (“MCC”). MCC is involved in the acquisition and operation of cable systems serving smaller cities and towns in the United States, and its cable systems are owned and operated through our operating subsidiaries and those of Mediacom LLC, a New York limited liability company wholly-owned by MCC. As limited liability companies, we and Mediacom LLC are not subject to income taxes and, as such, are included in the consolidated federal and state income tax returns of MCC, a C corporation.
	Our principal operating subsidiaries conduct all of our consolidated operations and own substantially all of our consolidated assets. Our operating subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to make funds available to us.
	We 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, 2013. 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, 2014.
	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 $5.8 million and $6.0 million for the three months ended September 30, 2014 and 2013, respectively, and approximately $17.4 million and $18.0 million for the nine months ended September 30, 2014 and 2013, respectively.
