(1) Organization

     Mediacom Broadband LLC (“Mediacom Broadband,” and collectively with its subsidiaries, the “Company”), 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.

     Mediacom Broadband relies on its parent, MCC, for various services such as corporate and administrative support. The financial position, results of operations and cash flows of Mediacom Broadband could differ from those that would have resulted had Mediacom Broadband operated autonomously or as an entity independent of MCC.

     Mediacom Broadband Corporation (“Broadband Corporation”), a Delaware corporation wholly-owned by Mediacom Broadband, co-issued, jointly and severally with Mediacom Broadband, 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 on its consolidated balance sheets. Therefore, separate financial statements have not been presented for this entity.

(2) Statement of Accounting Presentation and Other Information

  Basis of Preparation of Unaudited Consolidated Financial Statements

     Mediacom Broadband has prepared these unaudited consolidated financial statements as of March 31, 2005 and 2004. In the opinion of management, such statements include all adjustments, consisting of normal recurring accruals and adjustments, necessary for a fair presentation of the Company’s 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 additional disclosures, including a summary of the Company’s accounting policies, the interim unaudited consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2004 (File Nos. 333-72440 and 333-72440-01). 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, 2005.

  Revenue Recognition

     Revenues include amounts billed to customers for services provided, installations, advertising and other services. Revenues from video and data services are recognized when the services are provided to the customers. Installation revenues are less than direct installation costs. Therefore, installation revenues are recognized as connects are completed. Advertising sales are recognized in the period that the advertisements are exhibited. Franchise fees are collected on a monthly basis and are periodically remitted to local franchise authorities. Franchise fees collected and paid are reported as revenues and expenses as a component of selling, general and administrative.

  Programming Costs

     The Company has various fixed-term carriage contracts to obtain programming for its 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. The Company recognizes programming costs when it distributes the related programming. These programming costs are usually payable each month based on calculations performed by the Company and are subject to adjustments based on the results of periodic audits by the content suppliers. Historically, such audit adjustments have been immaterial to the Company’s 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, the Company defers them within non-current liabilities and recognizes 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.

  Allowance for Doubtful Accounts

     The allowance for doubtful accounts represents the Company’s best estimate of probable losses in the accounts receivable balance. The allowance is based on the number of days outstanding, customer balances, historical experience and other currently available information.

  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:

     The Company capitalizes improvements that extend asset lives and expenses repairs and maintenance as incurred. At the time of retirements, 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 presented as a separate component on the statement of operations.

     The Company capitalizes the costs associated with the construction of cable transmission and distribution facilities, the addition of network and other equipment and new customer installations. Costs include direct labor and material, as well as certain indirect costs including interest. The Company performs periodic evaluations of certain estimates used to determine the amount and extent that such costs that are capitalized. Any changes to these estimates, which may be significant, are applied prospectively 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.

  Long-Lived Assets

     In accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” the Company periodically evaluates the recoverability and estimated lives of its 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. When the carrying amount is not recoverable, 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.

  Intangible Assets

     In accordance with FASB 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. The Company has determined that its cable franchise costs and goodwill are indefinite-lived assets and therefore not amortizable. Other finite-lived intangible assets, which consist primarily of subscriber lists and covenants not to compete, continue to be amortized over their useful lives of 5 to 10 years and 5 years, respectively.

  Derivative Instruments

     The Company accounts for derivative instruments in accordance with SFAS No. 133, SFAS No. 138 and SFAS No. 149. These pronouncements require that all derivative instruments be recognized on the balance sheet at fair value. The Company’s stated strategy is to manage its interest expense using a combination of fixed and variable interest rate debt. The Company enters into interest rate exchange agreements to fix the interest rate on a portion of its variable interest rate debt to reduce the potential volatility in its interest expense that would otherwise result from changes in market interest rates. The Company’s derivative instruments are recorded at fair value and are included in other current assets, other assets and other liabilities. The Company’s accounting policies for these instruments are based on whether they meet the Company’s criteria for designation as hedging transactions. The criteria for designating a derivative as a hedge include the instrument’s effectiveness in risk reduction and, in most cases, a one-to-one matching of the derivative instrument to its underlying transaction. Gains and losses from changes in fair values of derivatives that are not designated as hedges for accounting purposes are recognized currently in earnings. The Company had no derivative financial instruments designated as hedges. Therefore, changes in fair value for the respective periods were recognized in earnings.

  Income Taxes

     Since the Company is a limited liability company, it is not subject to federal or state income taxes and no provision for income taxes relating to its operations has been reflected in the accompanying consolidated financial statements. Income or loss of the Company is reported in MCC’s income tax returns.

  Comprehensive Income

     SFAS No. 130, “Reporting Comprehensive Income,” requires companies to classify items of other comprehensive income by their nature in the financial statements and display the accumulated balance of other comprehensive income separately from retained earnings and paid-in capital in the equity section of a statement of financial position. The Company has had no other comprehensive income items to report.

  Reclassifications

     Certain reclassifications have been made to the prior year’s amounts to conform to the current year’s presentation.

(3) Recent Accounting Pronouncements

     In December 2004, the FASB issued SFAS No. 123R, “Amendment of Statement 123 on Share-Based Payment.” SFAS No. 123R requires companies to expense the value of employee stock options, stock granted through the employee stock purchase program and similar awards. On April 14, 2005, the SEC approved a new rule delaying the effective date until the beginning of a company’s next fiscal year that commences after June 15, 2005. The Company plans on adopting SFAS No. 123R effective January 1, 2006 and expects that the adoption of SFAS No. 123R will have a material impact on its consolidated results of operations.

(4) Property, Plant and Equipment

     As of March 31, 2005 and December 31, 2004, property, plant and equipment consisted of (dollars in thousands):

     Depreciation expenses for the three months ended March 31, 2005 and 2004 were approximately $28.4 million and $24.8 million, respectively. As of March 31, 2005 and 2004, the Company had property under capitalized leases of $5.5 million and $5.6 million, respectively, before accumulated depreciation, and $3.4 million and $4.8 million, respectively, net of accumulated depreciation. During the quarter ended March 31, 2005 and 2004, the Company incurred interest expense, net of interest income, of $23.7 million and $21.3 million, respectively, of which $0.3 million was capitalized for each period.

(5) Intangible Assets

     The Company operates its cable systems under non-exclusive cable franchises that are granted by state or local government authorities for varying lengths of time. The Company acquired these cable franchises through acquisitions of cable systems and the acquisitions were accounted for using the purchase method of accounting.

     On January 1, 2002, the Company adopted SFAS No. 142, “Goodwill and Other Intangible Assets,” which eliminates amortization of goodwill and certain intangibles that have indefinite lives but requires that such assets be tested for impairment at least annually. The Company evaluated the expected useful life of its cable franchises, also referred to as franchise costs, upon adoption of SFAS No. 142 and determined that all of its cable franchises have an indefinite useful life. As such, the Company ceased amortizing its cable franchises effective January 1, 2002.

     The Company has assessed franchise value for impairment under SFAS No. 142 by utilizing a discounted cash flow methodology. In performing an impairment test in accordance with SFAS No. 142, the Company considers the guidance contained in EITF Issue No. 02-7, “Recognition of Customer Relationship Intangible Assets acquired in a Business Combination,” whereby the Company considers assumptions, such as future cash flow expectations and other future benefits related to the intangible assets, when measuring the fair value of each cable systems other net assets. If the determined fair value of the Company’s franchise costs 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 the assets. To test the impairment of the goodwill carried on the Company’s financial statements, the fair value of the cable system cluster’s tangible and intangible assets (includes franchise costs) other than goodwill is deducted from the cable system cluster’s fair value. The balance represents the fair value of goodwill which is then compared to the carrying value of goodwill to determine if there is any impairment. The Company completed its last impairment test in accordance with SFAS No. 142 as of October 1, 2004, which reflected no impairment of franchise costs or goodwill. As of March 31, 2005, there were no events since then that would require an impairment analysis to be completed before the next annual test date.

     The following table summarizes the net asset value for each intangible asset category as of March 31, 2005 and December 31, 2004 (dollars in thousands):

     Amortization expense for the three months ended March 31, 2005 was approximately $0.5 million, as compared to $1.0 million for the respective period in 2004. The Company’s estimated future aggregate amortization expense for 2005 through 2009 and beyond are $1.6 million, $2.1 million, $2.1 million, $2.1 million and $7.5 million, respectively.

(6) Accrued Liabilities

     Accrued liabilities consist of the following as of March 31, 2005 and December 31, 2004 (dollars in thousands):

(7) Debt

     As of March 31, 2005 and December 31, 2004, debt consisted of (dollars in thousands):

     The average interest rates on outstanding debt under the bank credit facility were 4.8% and 3.3% as of March 31, 2005 and 2004, respectively, before giving effect to the interest rate exchange agreements discussed below. As of March 31, 2005, the Company had unused credit commitments of approximately $470.0 million under its bank credit facility, all of which could be borrowed and used for general corporate purposes based on the terms and conditions of the Company’s debt arrangements. The Company was in compliance with all covenants under its debt arrangements as of and for all periods through March 31, 2005.

     The Company uses interest rate exchange agreements in order to fix the interest rate on its floating rate debt. As of March 31, 2005, the Company had interest rate exchange agreements with various banks pursuant to which the interest rate on $500.0 million is fixed at a weighted average rate of approximately 3.4%. Under the terms of the interest rate exchange agreements, which expire from 2005 through 2007, the Company is exposed to credit loss in the event of nonperformance by the other parties. However, due to the creditworthiness of the Company’s counterparties, which are major banking firms with investment grade ratings, the Company does not anticipate their nonperformance. At the end of each quarterly reporting period, the carrying values of these swap agreements are marked to market. The fair values of these agreements is the estimated amount that the Company would receive or pay to terminate such agreements, taken into account market interest rates, the remaining time to maturity and the creditworthiness of the Company’s counterparties. At March 31, 2005, based on the mark-to-market valuation, the Company recorded on its consolidated balance sheet an accumulated investment in derivatives of $5.1 million, which is a component of other assets, and a derivative liability of $1.4 million, which is divided between accrued liabilities and other non-current liabilities.

     As a result of the mark-to-market valuations of these interest rate swaps, the Company recorded a gain of $5.0 million for the three months ended March 31, 2005, as compared to a loss of $4.2 million for the three months ended March 31, 2004.

     On January 25, 2005, the Company received an $88.0 million loan from Mediacom LLC, a New York limited liability company wholly- owned by MCC. This loan was in the form of a demand note, with 6.7% annual interest rate payable semi-annually in cash, and recorded as a component of the current portion of debt in the Company’s consolidated balance sheets and as new borrowings in its consolidated statements of cash flows. The proceeds from the loan were used to repay outstandings under the Company’s revolving credit facility.

     As of March 31, 2005, approximately $10.0 million letters of credit were issued to various parties as collateral for our performance relating primarily to insurance and franchise requirements.

(8) Preferred Members’ Interests

     Mediacom LLC has a $150.0 million preferred equity investment in the Company. The preferred equity investment has a 12% annual dividend, payable quarterly in cash. During the three months ended March 31, 2005 and 2004, the Company paid $4.5 million in cash dividends on the preferred equity.

(9) Stock-Based Compensation

     The Company accounts for stock-based compensation in accordance with APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations, as permitted by SFAS No. 123, “Accounting for Stock-Based Compensation,” (“SFAS No. 123”) as amended. Compensation expense for stock options, restricted stock units and other equity awards to employees is recorded by measuring the intrinsic value, defined as the excess, if any, of the quoted market price of the stock at the date of the grant over the amount an employee must pay to acquire the stock, and amortizing the intrinsic value to compensation expense over the vesting period of the award.

     During the quarter ended March 31, 2005, certain employees received grants of stock options and restricted stock units exercisable on underlying MCC shares. The stock option grants totaled 36,000 options which had an exercise price of $5.42 and vest equally over four years. The restricted stock units were granted in two tranches. The first tranche was a grant of 42,600 restricted stock units at a grant price of $5.69 and vests equally over four years. The second tranche was a grant of 145,000 restricted stock units at a grant price of $5.42 with a cliff vest at the end of four years.

     No compensation cost has been recognized for any option grants in the accompanying consolidated statements of operations since the price of the options was at their fair market value at the date of grant. As of March 31, 2005, the Company has recorded $1.0 million of intrinsic value related to the restricted stock unit awards as deferred compensation and paid-in capital in its consolidated balance sheets. During the three months ended March 31, 2005, the Company amortized $27,000 of deferred compensation as compensation expense in its consolidated statements of operations.

     Had the Company applied the fair value recognition provisions of SFAS No. 123 to stock-based compensation, the Company’s net income would have been changed from the “as reported” amounts to the “pro forma” amounts as follows (dollars in thousands):

(10) Legal Proceedings

     On April 5, 2004, a lawsuit was filed against MCC Georgia LLC, one of the Company’s subsidiaries, MCC, and other, currently unnamed potential defendants in the United States District Court for the District of Colorado by Echostar Satellite LLC, which operates a direct broadcast satellite business under the name “Dish Network”. Echostar alleges that systems operated by MCC Georgia LLC have used, without authorization, Dish Network satellite dishes activated under residential accounts to receive the signals of certain broadcast television stations in one or more locations in Georgia and that it has then been redistributing those signals, through its cable systems, to its subscribers. Among other claims, the complaint filed by Echostar alleges that these actions violate a provision of the Communications Act of 1934 (47 U.S.C. Sec. 605) that prohibits unauthorized interception of radio communications. The plaintiff seeks injunctive relief, actual and statutory damages, disgorgement of profits, punitive damages and litigation costs, including attorneys’ fees.

     On June 29, 2004, Echostar amended its complaint to also allege that this conduct amounted to a breach of the contract between Echostar and one of MCC’s employees, who allegedly acted as an agent for MCC, by which MCC received the Echostar satellite signal. On September 7, 2004, the U.S. District Court granted MCC’s motion to transfer the case to the Middle District of Georgia, where venue is proper and where personal jurisdiction over MCC exists. There were no proceedings for several months until Echostar filed a motion for default judgment on April 6, 2005. MCC filed a response opposing the motion and the court has not yet acted upon it.

     MCC and MCC Georgia LLC have advised the Company that they intend to vigorously defend against the claims made by Echostar. They have also informed the Company that they are unable to reasonably evaluate the likelihood of an unfavorable outcome or quantify the possible damages, if any, associated with these matters, or judge whether or not those damages would be material to their consolidated financial position, results of operations, cash flows or business.

     The Company, MCC and its subsidiaries or other affiliated companies 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 matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations, cash flows or business.

(11) Subsequent Events

     On April 26, 2005, the Company repaid the $88.0 million loan plus accrued interest to Mediacom LLC. The Company funded the repayment of this loan including accrued interest with a borrowing of $89.0 million under its revolving credit facility. As of this same date, after giving effect to the loan repayment and the accrued interest, the Company had unused commitments of about $375.0 million, all of which could be borrowed and used for general corporate purposes based on the terms and conditions of the Company’s debt arrangements.

     On May 3, 2005, the Company refinanced a $496.5 million term loan with a new term loan in the amount of $500.0 million. Borrowings under the new term loan bear interest at a rate that is 0.5% less than the interest rate of the term loan it replaced. The new term loan matures in February 2014, whereas the term loan it replaced had a maturity of September 2010.

     ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion should be read in conjunction with the Company’s unaudited consolidated financial statements as of, and for the three months ended, March 31, 2005 and 2004, and with the Company’s annual report on Form 10-K for the year ended December 31, 2004.

Overview

     We are a wholly-owned subsidiary of Mediacom Communications Corporation (“MCC”). Through our interactive broadband network, we provide our customers with a wide array of broadband products and services, including analog and digital video services, such as video-on-demand (“VOD”), high-definition television (“HDTV”), digital video recorders (“DVRs”) and high-speed data access (“HSD”) and beginning in the second quarter of 2005, cable telephony. We currently offer video and HSD bundles, and, when we introduce cable telephony, we will offer triple-play bundles of video, HSD and voice. Bundled products and services offer our subscribers a single provider contact for provisioning, billing and customer care.

     As of March 31, 2005, our cable systems passed an estimated 1.46 million homes and served 787,500 basic video subscribers. We provide digital video services to 254,500 digital customers, representing a penetration of 32.3% of our basic subscribers. We also currently provide HSD to 226,000 data customers, representing a penetration of 15.5% of our estimated homes passed.

     We have faced increasing levels of competition for our video programming services over the past few years, mostly from direct broadcast satellite (“DBS”) service providers. Since they have been permitted to deliver local television broadcast signals beginning in 1999, DirecTV, Inc. and Echostar Communications Corporation, the two largest DBS service providers, have been increasing the number of markets in which they deliver these local television signals. These “local-into-local” launches have been the primary cause of our loss of basic subscribers in recent periods. By year-end 2004, competitive local-into-local services in our markets covered an estimated 92% of our basic subscribers, as compared to an estimated 75% at year-end 2003. We believe, based on publicly announced new market launches, that DBS service providers will launch local television channels in additional markets representing a modest amount of our subscriber base in 2005.

Actual Results of Operations

  Three Months Ended March 31, 2005 Compared to Three Months Ended March 31, 2004

     The following table sets forth the unaudited consolidated statement of operations for the three months ended March 31, 2005 and 2004 (dollars in thousands and percentage changes that are not meaningful are marked NM):

  Revenues

     The following table sets forth revenue information for the three months ended March 31, 2005 and 2004 (dollars in millions):

13

     Video revenues decreased 0.7%, as a result of a 2.9% reduction in basic video subscribers from 811,000 as of March 31, 2004, to 787,500 as of March 31, 2005, significantly offset by the full impact of basic rate increases applied on our video subscribers during 2004 and higher service fees from advanced video products. Average monthly video revenue per basic video subscriber increased 3.1% from $47.36 to $48.82. Our loss in basic video subscribers in 2004 resulted primarily from increased competitive pressures by DBS service providers, and, to a lesser extent, from our tightened customer credit policies, which were imposed throughout 2004. To reverse this video subscriber trend, we have been increasing customer retention efforts and our emphasis on product bundling, as well as enhancing and differentiating our video products and services with new digital packages, VOD, HDTV, DVRs and more local programming. As a result of these efforts, basic video subscribers and digital customers increased by 4,500 and 18,500, respectively during the three months ended March 31, 2005.

     Data revenues rose 20.6% primarily due to a 33.7% year-over-year increase in data customers from 169,000 to 226,000 and, to a lesser extent, an increased contribution from our commercial enterprise business. Average monthly data revenue per data customer decreased from $42.48 to $38.97, largely due to discounted video and data bundles introduced in mid-year 2004.

     Advertising revenues increased 6.3%, as a result of stronger national advertising. This was offset in part by a decline in political advertising, which is expected to be much lower in 2005 when compared to the 2004 election year.

  Costs and Expenses

     Service costs include: fees paid to programming suppliers; employee expenses related to wages and salaries of technical personnel who maintain our cable network and perform customer installation activities; data costs, including costs of bandwidth connectivity, customer provisioning and technical support and field operating costs, including outside contractors, vehicle, utilities and pole rental expenses. Programming costs, which are payments to programmers for content and are generally paid on a per subscriber basis, have historically increased due to both increases in the rates charged for existing programming services and the introduction of new programming services to our customers.

     Service costs increased 5.1%, primarily due to increases in programming, field operating, data and employee costs. Programming costs increased 2.3%, as a result of higher unit costs charged by programming suppliers and lower launch support received from them in return for our carriage of their services, significantly offset by our basic video subscriber losses in 2004. Field operating costs rose 34.7%, primarily due to the greater use of outside contractors to service higher levels of customer activity and, to a lesser extent, increases in converter repair and vehicle fuel costs. Data costs increased 14.9% to service the growth in our data customers. Employee related costs grew 0.9%, primarily due to increased overtime and commissions related to higher levels of customer activity, significantly offset by a decrease in certain employee insurance expenses. Service costs as a percentage of revenues were 39.0% and 38.2% for the three months ended March 31, 2005 and March 31, 2004, respectively.

     Selling, general and administrative expenses include: wages and salaries for our call center, customer service and support and administrative personnel; franchise fees and taxes; and office costs related to billing, telecommunications, marketing, bad debt, advertising and office administration.

     Selling, general and administrative expenses rose 3.9%, principally due to higher marketing, office and employee costs, partially offset by a significant decrease in bad debt expense. Marketing costs grew 30.6% as a result of increased costs associated with contracted direct sales personnel and advertising campaigns to support greater sales of our products and services. Office costs rose 32.6%, mainly due to higher telephone costs related to the greater call volumes and the use of contracted call center services. Employee costs increased 2.9% due to higher employee compensation, including commissions. This increase in selling, general and administrative expense was significantly offset by a 35.4% decrease in bad debt expense as a result of improved customer credit and collection policies. As a percentage of revenues, selling, general and administrative expenses were 22.3% and 22.0% for the three months ended March 31, 2005 and 2004, respectively.

14

     We expect continued revenue growth in advanced services, which include digital video, HDTV, DVRs, and HSD and, in the first half of 2005, the launch of cable telephony service. As a result, we expect our service costs and selling, general and administrative expenses to increase.

     Management fee expense reflects charges incurred under our management arrangements with our parent, MCC. Management fee expense increased 7.9%, which reflects greater overhead costs charged by MCC during the three month period ended March 31, 2005. As a percentage of revenues, management fee expense was 1.9% for the three months ended March 31, 2005 and 2004.

     Depreciation and amortization increased 11.7%, principally due to increased depreciation for ongoing investments to continue the rollout of products and services such as VOD, HDTV, DVRs and HSD and the investments in our cable network.

  Interest Expense, Net

     Interest expense, net, increased 11.7%, primarily due to higher market interest rates on variable rate debt and to a lesser extent, higher average indebtedness for the three months ended March 31, 2005 as compared to the respective period in 2004.

  Gain (loss) on Derivatives, Net

     We enter into interest rate exchange agreements or “interest rate swaps”, with counterparties to fix the interest rate on a portion of our variable rate debt to reduce the potential volatility in our interest expense that would otherwise result from changes in variable market interest rates. As of March 31, 2005, we had interest rate swaps with an aggregate principal amount of $500.0 million. The changes in their mark-to-market values are derived from changes in market interest rates, the decrease in their time to maturity and the creditworthiness of the counterparties. As a result of the mark-to-market valuation of these interest rate swaps, we recorded a gain on derivatives amounting to $5.0 million for the three months ended March 31, 2005, as compared to a loss on derivatives of $4.2 million for the three months ended March 31, 2004.

  Other Expense

     Other expense was $1.0 million and $1.1 million for the three months ended March 31, 2005 and 2004, respectively. Other expense primarily represents amortization of deferred financing costs and fees on unused credit commitments.

  Net Income

     As a result of the factors described above, we generated net income for the three months ended March 31, 2005 of $6.3 million, as compared to net income of $2.7 million for the three months ended March 31, 2004.

Liquidity and Capital Resources

  Overview

     As an integral part of our business plan, we have invested, and will continue to invest significant amounts in our cable systems to enhance their reliability and capacity, which allows for the introduction of new advanced broadband services. Our capital investments have recently shifted away from the cable systems’ broadband network and to the deployment of new products and services, including VOD, HDTV, DVRs, HSD and cable telephony. In the three months ended March 31, 2005, we made $22.8 million of capital expenditures. Although we did not make any strategic acquisitions or sales of cable systems during the three months ended March 31, 2005, we have historically entered into such transactions and may continue to do so in the future.

     We have a significant level of debt. As of March 31, 2005, our total debt was $1.37 billion. Of this amount, $38.2 million and $49.5 million will mature within the twelve months ending March 31, 2006 and 2007, respectively, excluding the $88.0 million loan we repaid on April 26, 2005, as discussed below. Given our level of indebtedness, we also have significant interest expense obligations. During the quarter ended March 31, 2005 we paid cash interest of $30.3 million. Our cash interest payments have historically been higher in the first and third calendar quarters of the year due to the timing of the cash interest payments on our senior notes.

     During the three months ended March 31, 2005, we generated $25.9 million of net cash flows from operating activities. We had cash flows from financing activities of $6.1 million, and a decrease in cash of $3.0 million. We used these sources to fund our cash requirements, including capital expenditures.

     As of March 31, 2005, we had unused credit commitments of about $470.0 million under our credit facility, all of which could be borrowed and used for general corporate purposes based on the terms and conditions of our debt arrangements. For all periods through March 31, 2005, we were in compliance with all of the covenants under our debt arrangements. Continued access to our credit facility is subject to our remaining in compliance with the covenants of our credit facility, including covenants tied to our operating performance. We believe that we will not have any difficulty in the foreseeable future complying with these covenants and that we will meet our current and long-term debt service, capital spending and other cash requirements through a combination of our net cash flows from operating activities, borrowing availability under our bank credit facility and our ability to secure future external financing. However, there can be no assurance that we will be able to obtain sufficient future financing, or, if we were able to do so, that the terms would be favorable to us.

  Operating Activities

     Net cash flows provided by operating activities were $25.9 million and $20.7 million for the three months ended March 31, 2005 and 2004, respectively. This increase was principally due to the timing of cash receipts and expenses in our working capital accounts, mainly from accrued liabilities, offset in part by a decline in operating income.

  Investing Activities

     Net cash flows used in investing activities were $22.8 million and $17.5 million for the three months ended March 31, 2005 and 2004, respectively. Substantially all of the cash flows used in investing activities have been for capital expenditures. Capital expenditures were $22.8 million and $17.2 million for the three months ended March 31, 2005 and 2004, respectively. For the three month period ending March 31, 2005, these expenditures increased mainly as a result of purchases of more units of customer premise equipment, including higher-cost advanced digital boxes, and increased installation activity.

  Financing Activities

     Net cash flows used in financing activities were $6.1 million and $7.7 million for the three months ended March 31, 2005 and 2004, respectively. During the three months ended March 31, 2005, we borrowed $88.0 million in the form of a demand note from Mediacom LLC, a wholly-owned subsidiary of MCC, and used the proceeds to repay a portion of our indebtedness under our revolving credit facility.

16

  Other

     On April 26, 2005, we repaid the loan plus accrued interest to Mediacom LLC. We funded the repayment of the loan including accrued interest with a borrowing of $89.0 million under our revolving credit facility. As of that same date, after giving effect to the loan repayment and the accrued interest, we had unused commitments of about $375.0 million, all of which could be borrowed and used for general corporate purposes based on the terms and conditions of our debt arrangements.

     On May 3, 2005, we refinanced a $496.5 million term loan with a new term loan in the amount of $500.0 million. Borrowings under the new term loan bear interest at a rate that is 0.5% less than the interest rate of the term loan it replaced. The new term loan matures in February 2014, whereas the term loan it replaced had a maturity of September 2010.

     We have entered into interest rate exchange agreements with counterparties, which expire from September 2005 through March 2007, to hedge $500.0 million of floating rate debt. Under the terms of all of our interest rate exchange agreements, we are exposed to credit loss in the event of nonperformance by the other parties of the agreements. However, due to the high creditworthiness of our counterparties, which are major banking firms with investment grade ratings, we do not anticipate their nonperformance. As of March 31, 2005, about 73% of our outstanding indebtedness was at fixed interest rates or subject to interest rate protection and our annualized cost of debt capital was approximately 6.8%.

     As of March 31, 2005, approximately $10.0 million of letters of credit were issued to various parties as collateral for our performance relating primarily to insurance and franchise requirements.

Contractual Obligations and Commercial Commitments

     The following table summarizes our contractual obligations and commercial commitments, and the effects they are expected to have on our liquidity and cash flow, for the five years subsequent to March 31, 2005 and thereafter (dollars in thousands)*:

Critical Accounting Policies

     The foregoing discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Periodically, we evaluate our estimates, including those related to doubtful accounts, long-lived assets, capitalized costs and accruals. We base our estimates on historical experience and on various other assumptions that we believe are reasonable. Actual results may differ from these estimates

under different assumptions or conditions. We believe that the application of the critical accounting policies discussed below requires significant judgments and estimates on the part of management. For a summary of our accounting policies, see Note 2 of our unaudited consolidated financial statements.

  Revenue Recognition

     Revenues include amounts billed to customers for services provided, installations, advertising and other services. Revenues from video and data services are recognized when the services are provided to the customers. Installation revenues are less than direct installation costs. Therefore, installation revenues are recognized as connects are completed. Advertising sales are recognized in the period that the advertisements are exhibited. Franchise fees are collected on a monthly basis and are periodically remitted to local franchise authorities. Franchise fees collected and paid are reported as revenues and expenses as a component of selling, general and administrative.

  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. We recognize programming costs 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 and recognize such amounts as a reduction of programming costs (which are a component of service costs in our consolidated statement of operations) over the carriage term of the programming contract.

  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, historical experience and other currently available information.

  Property, Plant and Equipment

     We capitalize the costs of new construction and replacement of our cable transmission and distribution facilities; the addition of network and other equipment, and new customer service installations. Capitalized costs include all direct labor and materials as well as certain indirect costs and are based on historical construction and installation costs. Capitalized costs are recorded as additions to property, plant and equipment and depreciate over the life of the related asset. We perform periodic evaluations of certain estimates used to determine the amount and extent of such costs that are capitalized. Any changes to these estimates, which may be significant, are applied prospectively in the periods in which the evaluations were completed.

  Long-Lived Assets

     In accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” 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. When the carrying amount is not recoverable, 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. Any loss is included as a component of either depreciation expense or amortization expense, as appropriate, unless it is material to the period in question whereby we would present it separately.

18

  Intangible Assets

     In accordance with 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 costs are indefinite-lived assets. We completed our most recent impairment test as of October 1, 2004, which reflected no impairment of our franchise costs and goodwill. As of March 31, 2005, there were no events since then that would require an analysis to be completed before the next annual test date.

  Derivative Instruments

     We account for derivative instruments in accordance with SFAS No. 133, SFAS No. 138 and SFAS No. 149. Our primary objective for holding derivative financial instruments is to manage interest rate risk. Our derivative instruments are recorded at fair value and are included in other current assets, other assets and other liabilities. Our accounting policies for these instruments are based on whether they meet our criteria for designation as hedging transactions. The criteria for designating a derivative as a hedge include the instrument’s effectiveness in risk reduction and, in most cases, a one-to-one matching of the derivative instrument to its underlying transaction. We have no derivative financial instruments designated as hedges. Gains and losses from changes in the mark-to-market values are currently recognized in earnings. Short-term valuation changes derived from changes in market interest rates, time to maturity and the creditworthiness of the counterparties may increase the volatility of earnings.

Recent Accounting Pronouncements

     In December 2004, the FASB issued SFAS No. 123R, “Amendment of Statement 123 on Share-Based Payment.” SFAS No. 123R requires companies to expense the value of employee stock options, stock granted through the employee stock purchase program and similar awards. SFAS No. 123R was originally effective for interim periods beginning after June 15, 2005. On April 14, 2005, the Securities and Exchange Commission approved a new rule delaying the effective date the beginning of a company’s next fiscal year that commences after June 15, 2005. We plan on adopting SFAS No. 123R effective January 1, 2006 and expect that the adoption of SFAS No. 123R will have a material impact on our consolidated results of operations.

Inflation and Changing Prices

     Our systems’ costs and expenses are subject to inflation and price fluctuations. Such changes in costs and expenses can generally be passed through to subscribers. Programming costs have historically increased at rates in excess of inflation and are expected to continue to do so. We believe that under the Federal Communications Commission’s existing cable rate regulations we may increase rates for cable television services to more than cover any increases in programming. However, competitive conditions and other factors in the marketplace may limit our ability to increase our rates.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     In the normal course of business, we use interest rate swaps to fix the interest rate on our variable interest rate debt. As of March 31, 2005, we had $500.0 million of interest rate swaps with various banks at a weighted average fixed rate of approximately 3.4%. The fixed rates of the interest rate swaps are offset against the applicable three-month London Interbank Offering Rate to determine the related interest expense. Under the terms of the interest rate exchange agreements, which expire from 2005 through 2007, we are exposed to credit loss in the event of nonperformance by the other parties. However, due to the high creditworthiness of our counterparties, which are major banking firms with investment grade ratings, we do not anticipate their nonperformance. At March 31, 2005, based on the mark-to-market valuation, we would have received approximately $3.7 million, including accrued interest, if we terminated these agreements.

     The table below provides the expected maturity and estimated fair value of our debt as of March 31, 2005 (dollars in thousands). See Note 7 to our unaudited consolidated financial statements.
