Cautionary Note Regarding Forward-Looking Statements

Certain statements in the Quarterly Report on Form 10-Q may constitute “forward-looking” statements as defined in Section 27A of the Securities Act of 1933 (the “Securities Act”), Section 21E of the Securities Exchange Act of 1934 (the “Exchange Act”), the Private Securities Litigation Reform Act of 1995 (the “PSLRA”) or in releases made by the Securities and Exchange Commission (“SEC”), all as may be amended from time to time. Such forward-looking statements involve known and unknown risks, uncertainties and other important factors that could cause the actual results, performance or achievements of MSW Energy Holdings LLC (together with its subsidiaries, “MSW I”), and MSW Energy Holdings II LLC (together with its subsidiaries, “MSW II”), or industry results, to differ materially from any future results, performance or achievements expressed or implied by such forward-looking statements. Statements that are not historical fact are forward-looking statements. Forward-looking statements can be identified by, among other things, the use of forward-looking language, such as the words “plan,” “believe,” “expect,” “anticipate,” “intend,” “estimate,” “project,” “may,” “will,” “would,” “could,” “should,” “seeks,” or “scheduled to,” or other similar words, or the negative of these terms or other variations of these terms or comparable language, or by discussion of strategy or intentions. These cautionary statements are being made pursuant to the Securities Act, the Exchange Act and the PSLRA with the intention of obtaining the benefits of the “safe harbor” provisions of such laws. MSW I and MSW II caution investors that any forward-looking statements made by MSW I and MSW II are not guarantees nor are they indicative of future performance. Important assumptions and other important factors that could cause actual results to differ materially from those forward-looking statements with respect to MSW I and MSW II, include, but are not limited to, the risks and uncertainties affecting their businesses described in Item 1A of their respective MSW I and MSW II Annual Reports on Form 10-K for the year ended December 31, 2005 and in other securities filings by MSW I and MSW II and in Item 1A of Covanta Holding Corporation’s (“Covanta”) Annual Report on Form 10-K for the year ended December 31, 2005 and Item 1A of Part II of Covanta’s Quarterly Report on form 10-Q for the quarter ended September 30, 2006 and in other securities filings by Covanta.

Although MSW I and MSW II believe that their plans, intentions and expectations reflected in or suggested by such forward-looking statements are reasonable, actual results could differ materially from a projection or assumption in any of their forward-looking statements. The future financial condition and results of operations for MSW I and MSW II, as well as any forward-looking statements, are subject to change and inherent risks and uncertainties. The forward-looking statements contained in this Quarterly Report on Form 10-Q are made only as of the date hereof and MSW I and MSW II do not have or undertake any obligation to update or revise any forward-looking statements whether as a result of new information, subsequent events or otherwise, unless otherwise required by law.

Note 1.	Organization and Basis of Presentation

Organization

MSW Energy Holdings LLC

MSW Energy Holdings LLC, a Delaware limited liability company (collectively herein with its subsidiaries “MSW I”) and currently a subsidiary of Covanta ARC Holdings Inc. (“Covanta ARC Holdings”), was formed in March 2003 for the purpose of acquiring a 50% indirect membership interest in Covanta Ref-Fuel Holdings LLC (“Covanta Ref-Fuel”). At the initial closing on June 30, 2003, MSW I acquired MSW Energy Hudson LLC (“MSW Hudson”), which held a 49.8% membership interest in Covanta Ref-Fuel. MSW I had agreed to acquire MSW Energy Erie LLC, formerly known as Duke Energy Erie LLC (“Erie”), a wholly-owned subsidiary of Duke Energy Corporation (“Duke”) that held an additional 0.2% membership interest in Covanta Ref-Fuel within two years and six months after the purchase of MSW Hudson. MSW I consummated this transaction and acquired the remaining 0.2% membership interest on September 30, 2005. MSW Energy Finance Co., Inc. (“MSW Energy Finance”), a Delaware corporation and wholly-owned subsidiary of MSW I, was formed in June 2003 solely for the purpose of serving as a co-issuer of the MSW I 8.50% Senior Notes due 2010 described below. Other than serving as a co-issuer of the MSW I 8.50% Senior Notes due 2010, MSW Energy Finance does not have any operations or assets and does not have any revenues.

MSW Energy Holdings II LLC

MSW Energy Holdings II LLC, a Delaware limited liability company (collectively herein with its subsidiaries “MSW II”), and its wholly-owned subsidiary MSW Energy Finance Co. II, Inc. (“MSW Energy Finance II”), a Delaware corporation, were formed in August 2003 for the purpose of issuing debt, the proceeds of which, along with capital contributions, were used to fund the merger of MSW Merger LLC, MSW II’s then indirect parent, with and into an indirect, wholly-owned subsidiary of Covanta ARC Holdings (the “Merger”). After the Merger, Covanta Ref-Fuel II Corp. (“Covanta Ref-Fuel II”), a Delaware corporation and an indirect subsidiary of Covanta ARC Holdings, became a subsidiary of MSW II. The Merger was completed on December 12, 2003, and after the completion of the Merger, MSW II held a direct 49.9% capital interest in Covanta Ref-Fuel and wholly-owned Covanta Ref-Fuel II, which owned a 0.1% capital interest in Covanta Ref-Fuel. Both interests were contributed to MSW II by Covanta ARC Holdings. Other than serving as a co-issuer of the MSW II 7.375% Senior Notes due 2010, MSW Energy Finance II does not have any operations or assets and does not have any revenues.

MSW I and MSW II

The following chart reflects a simplified ownership structure of MSW I, MSW Energy Finance, MSW II and MSW Energy Finance II. Unless otherwise noted, ownership interests are 100%:

Notes to Condensed Consolidated Financial Statements — (Unaudited)

Covanta ARC LLC (“Covanta ARC”), a wholly-owned subsidiary of Covanta Ref-Fuel, owns partnerships that develop, own and operate waste-to-energy facilities, which combust municipal solid waste and produce energy in the form of electricity and steam. Through such partnerships, Covanta ARC owns or controls six waste-to-energy facilities located in the northeastern United States (the “ARC operating facilities”). The subsidiaries of Covanta ARC that operate the ARC operating facilities (the “ARC operating companies”) derive revenues principally from disposal or tipping fees received for accepting waste and from the sale of electricity and steam produced by the ARC operating facilities. ARC operating subsidiaries include: (a) Covanta ARC Company; (b) TransRiver Marketing Company, L.P.; (c) Covanta Hempstead Company (“Hempstead”); (d) Covanta Essex Company (“Essex”); (e) Covanta Southeastern Connecticut Company (“Seconn”); (f) Covanta Niagara, L.P. (“Niagara”); (g) Covanta Company of Semass, L.P. (“Semass”); (h) Covanta of Semass, L.P.; and (i) Covanta Delaware Valley, L.P. (“Delaware Valley”).

Effective June 24, 2005, Covanta Holding Corporation (“Covanta”), a Delaware corporation, through its wholly-owned subsidiary, Covanta Energy Corporation (“Covanta Energy”), a Delaware corporation, acquired all of the issued and outstanding shares of capital stock of Covanta ARC Holdings (the “Acquisition”). The Acquisition was made pursuant to the terms of a Stock Purchase Agreement, dated as of January 31, 2005 among Covanta, Covanta ARC Holdings and the stockholders of Covanta ARC Holdings. As a result of the Acquisition, Covanta, through Covanta Energy, owns 100% of the voting securities of Covanta ARC Holdings.

Covanta Energy paid approximately $747 million, including transaction costs, for the shares of Covanta ARC Holdings and assumed the consolidated net debt of Covanta ARC Holdings, which was approximately $1.3 billion as of June 24, 2005 ($1.5 billion of consolidated indebtedness net of $0.2 billion of cash and restricted cash). Upon consummation of the Acquisition, a change in ownership occurred, and in accordance with Emerging Issues Task Force (“EITF”) Topic D-97, “Push-Down Accounting” (“EITF D-97”), the financial statements of MSW I and MSW II reflect the effects of their change in ownership and the new owner’s basis in the net assets and liabilities acquired. Further, the change in basis in the net assets and liabilities acquired, including goodwill that was recorded in connection with the Acquisition, was pushed down to Covanta ARC and certain of its subsidiaries in accordance with EITF D-97. As a result, the statement of operations and the statement of cash flows for the period from January 1 through June 24, 2005 reflect the results of operations prior to purchase accounting adjustments and the balance sheet at December 31, 2005, the statements of operations for the three and nine months ended September 30, 2006 and for the period from June 25 through September 30, 2005 and statements of cash flows for the nine months ended September 30, 2006 and for the period from June 25 through September 30, 2005, reflect the impact of the purchase price allocation arising from the Acquisition.

Basis of Presentation

This combined Quarterly Report on Form 10-Q is filed for MSW I, MSW Energy Finance, MSW II and MSW Energy Finance II. Information contained herein relating to any individual company is filed by such company on its own behalf. MSW I, MSW Energy Finance, MSW II and MSW Energy Finance II each make representations only as to itself and its subsidiaries and make no other representations whatsoever as to any other company.

The statements of operations, balance sheets and cash flow statements for MSW I and MSW II each include the consolidated results of their respective operations and the results of operations of Covanta Ref-Fuel and its subsidiaries. As shown in the chart above, MSW I and MSW II each own, directly and indirectly, 50% of Covanta Ref-Fuel, which owns 100% of Covanta ARC. As such, the results of operations, balance sheets and cash flow statements for each of MSW I and MSW II include the consolidated results of Covanta Ref-Fuel along with the minority interest adjustment for the 50% ownership interest of the other.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q. As permitted by the rules and regulations of the Securities and Exchange Commission (the “SEC”), the financial statements contain certain condensed financial information and exclude certain footnote disclosures normally included in audited consolidated financial statements prepared in accordance with United States generally accepted accounting principles. In presenting the unaudited condensed consolidated

Notes to Condensed Consolidated Financial Statements — (Unaudited)

financial statements, management made estimates and assumptions that affected the amounts reported and related disclosures. Estimates, by their nature, are based on judgments and available information. Accordingly, actual results could differ from those estimates. In the opinion of management, the accompanying financial statements contain all adjustments, including normal recurring accruals, necessary to fairly present the accompanying condensed consolidated financial statements. Operating results for the interim period are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2006. Certain prior period amounts have been reclassified to conform to the current year’s presentation. For further information, refer to the consolidated financial statements and footnotes thereto included in the respective MSW I and MSW II Annual Reports on Form 10-K for the year ended December 31, 2005.


Note 2.	New Accounting Pronouncements

In June 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109” (“FIN 48”). This interpretation increases the relevancy and comparability of financial reporting by clarifying the way companies account for uncertainty in income taxes. FIN 48 prescribes a consistent recognition threshold and measurement attribute, as well as clear criteria for subsequently recognizing, derecognizing and measuring such tax positions for financial statement purposes. The interpretation also requires expanded disclosure with respect to the uncertainty in income taxes. FIN 48 is effective for fiscal years beginning after December 15, 2006. MSW I and MSW II are currently evaluating the potential impact of this interpretation on its consolidated financial statements.

In September 2006, the FASB issued Statement of Financial Accounting Standards (“SFAS”) No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS 157 will be applied under other accounting principles that require or permit fair value measurements, as this is a relevant measurement attribute. This statement does not require any new fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. MSW I and MSW II are currently evaluating the impact of this statement on its consolidated financial statements.

Note 3. Business Combinations

MSW I and MSW II

In connection with the Acquisition, the assets of Covanta ARC Holdings were valued by independent appraisers in order to assist Covanta management in the determination of the purchase price allocations relating to the fair market value of the assets and liabilities acquired on June 24, 2005.

Note 9.	Commitments and Contingencies

MSW I and MSW II

MSW I and MSW II and/or their subsidiaries are party to a number of claims, lawsuits and pending actions, most of which are routine and all of which are incidental to their business. MSW I and MSW II assess the likelihood of potential losses on an ongoing basis and when losses are considered probable and reasonably estimable, record as a loss an estimate of the ultimate outcome. If MSW I and MSW II can only estimate the range of a possible loss, an amount representing the low end of the range of possible outcomes is recorded. The final consequences of these proceedings are not presently determinable with certainty.

Environmental Matters

MSW I and MSW II

MSW I and MSW II operate in an environmentally sensitive industry and are subject to extensive federal, state and local laws and regulations adopted for the protection of the environment. The laws and regulations primarily applicable to MSW I and MSW II are those related to discharge of emissions into the air and management of solid waste, but can also include those related to water use, discharges to water, wetlands preservation and hazardous waste management. Certain of these laws have extensive and complex requirements relating to obtaining construction and operating permits, monitoring, record keeping and reporting. While management of each respective company believes that it is in substantial compliance with permits and other applicable environmental laws relating to MSW I and MSW II, their facilities, from time to time, may not be in full compliance with all such laws.

Noncompliance with environmental laws and regulations can result in the imposition of civil or criminal fines or penalties. In some instances, environmental laws may also impose clean-up or other remedial obligations in the event of a release of pollutants or contaminants into the environment. MSW I and MSW II incur operating costs and

Notes to Condensed Consolidated Financial Statements — (Unaudited)

capital expenditures related to various environmental protection and monitoring programs. Such expenditures have not had a material adverse effect on the consolidated financial position or results of operations of MSW I and MSW II, respectively. However, federal, state and local regulatory authorities may consider proposals to restrict or tax certain emissions, which proposals, if adopted, could impose additional costs on the operation of MSW I and MSW II.

By letters dated August 13, 2004 and May 3, 2005, the Environmental Protection Agency (“EPA”) notified the Essex facility that it was potentially liable under Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) Section 107(a) for response actions in the Lower Passaic River Study Area (“LPRSA”), a 17-mile stretch of river in northern New Jersey. Essex is one of at least 60 potentially responsible parties (“PRPs”) named thus far. EPA alleged that hazardous substances found in the LPRSA were being released from the Essex site, which abuts the river. EPA’s notice letters stated that Essex may be liable for costs related to a proposed remedial investigation and feasibility study (“RI/FS”) of the Lower Passaic River, for certain past costs incurred by EPA and for unspecified natural resource damages. Essex entered into an arrangement with EPA and the cooperating PRP group of which Essex is a member to settle the potential liability Essex might have for the $2.8 million in past costs incurred by EPA, and for the $10 million then estimated by EPA as the cost of the RI/FS by contributing $0.25 million to the cost of the RI/FS and by agreeing to share in certain past and ongoing legal fees and other costs of the cooperating PRP group. It is anticipated that additional contributions to the cost of the RI/FS will be required of PRP’s, including Essex, as the RI/FS proceeds through its predicted completion in 2010. Considering the history of industrial and other discharges into the LPRSA from other sources, including named PRPs, Essex believes any releases from its site to be de minimus in comparison; however, it is not possible at this time to predict that outcome with certainty or to estimate Essex’s ultimate liability in the matter, including for natural resource damages.

Other Matters

MSW I and MSW II

MSW I and MSW II are involved in various claims or litigation in the ordinary course of business. Management believes that the ultimate resolution of these matters, either individually or in the aggregate, will not have a material impact on the future results of operations, cash flows or financial position of MSW I or MSW II.

Mercury Regulation at Essex. On December 6, 2004, the New Jersey Department of Environmental Protection (“NJDEP”) promulgated regulations applicable to the Essex facility that will make mercury emission requirements more stringent. Specifically, the new regulations increase the required removal efficiency to 85% removal on January 3, 2006 and 95% removal on January 3, 2012, while retaining the alternative limit of 28 micrograms per cubic meter. As a result of the new regulations, there is an increased risk that emission exceedances will occur and therefore an increased probability that additional controls will ultimately be required to prevent such exceedances. MSW I and MSW II believe that the new requirements may at a minimum result in increased operating costs due to increased use of activated carbon in the existing control equipment. MSW I and MSW II have not incurred increased costs to date as the facility is in compliance with the currently applicable mercury regulations, but cannot currently determine the likelihood of additional future capital and operating costs being incurred to maintain compliance with those changes in regulations, or the total of any such costs. If additional cost is required, it is not anticipated to have a material impact on MSW I or MSW II because the Essex service agreement provides a mechanism for a pass-through to the Port Authority of New York and New Jersey for the majority of any additional capital costs and all operating costs that may be required.

CMW Landfill. Semass Partnership, a 90% owned subsidiary of Semass, has a waste management agreement (the “WMA”) dated May 25, 1982, as amended, with the Carver, Marion, Wareham Regional Refuse Disposal District (“CMW”). The WMA allows Semass Partnership to utilize a portion of a landfill (the “CMW Landfill”), which CMW leases from Wankinco River, Inc. (“Wankinco”).

In March 1990, the Semass Partnership, CMW and Wankinco entered into an agreement related to the CMW Landfill, as amended (the “Settlement Agreement”), which requires, among other things, the Semass Partnership to

Notes to Condensed Consolidated Financial Statements — (Unaudited)

make annual deposits into an environmental protection trust fund (the “Fund”) in lieu of obtaining environmental impairment liability insurance for the CMW Landfill. The Semass Partnership is required under the Settlement Agreement to deposit $0.5 million annually into the Fund, payable in equal quarterly installments. Certain additional deposits are required subject to the availability of cash in accordance with the Loan Agreement. The Semass Partnership’s obligation to make deposits into the Fund ceases when the Fund reaches a balance of $20 million unless the fund limit is increased by agreement of the parties, or absent such agreement, by arbitration, wherein it is determined the fund limit needs to be increased to adequately protect against environmental damage. Wankinco by letter dated March 29, 2005, and pursuant to its rights under the Settlement Agreement, has requested a re-evaluation of the Fund limit and an increase of such limit to $29.7 million. Management believes that the $20 million fund limit is adequate for its intended purpose. Discussions between Semass Partnership and Wankinco about the Fund limit are ongoing; no arbitration has been commenced. Proceeds from the Fund are to be used primarily for remediation of the CMW Landfill in the event of environmental damage. The Semass Partnership and Wankinco are each entitled to receive one-half of the balance of the Fund upon final closure of the CMW Landfill and receipt of required governmental approvals. During the nine months ended September 30, 2006 and the year ended December 31, 2005, the Semass Partnership made the required quarterly deposits into the Fund and charged operations for one-half of the deposits into the Fund, representing one-half of the balance of the Fund which will be disbursed to Wankinco upon final closure of the CMW Landfill. Additional charges to operations may be required in future years if any disbursements are required from the Fund to remediate any environmental damages. To date, management is not aware of any such environmental damages. As of September 30, 2006 and December 31, 2005, the balance in the Fund was approximately $18.0 million and $17.3 million, respectively, and was included in the long-term portion of restricted funds held in trust. A corresponding liability, representing approximately one-half of the deposits and related earnings in the Fund, was included in other long-term liabilities.

MSW I and MSW II and certain of their subsidiaries have issued or are party to performance guarantees and related contractual support obligations undertaken mainly pursuant to agreements to construct and operate certain waste-to-energy facilities. MSW I and MSW II and certain of their subsidiaries have issued guarantees to municipal clients and other parties that their subsidiaries will perform in accordance with contractual terms, including, where required, the payment of damages or other obligations. Such contractual damages or other obligations could be material, and in circumstances where one or more subsidiary’s contract has been terminated for its default, such damages could include amounts sufficient to repay project debt. MSW I and MSW II have not recorded any amount as a liability in their condensed consolidated balance sheet as of September 30, 2006 as they believe that they have not incurred such liability at the date of the financial statements. If MSW I and MSW II are asked to perform under one or more such guarantees, their liability for damages upon contract termination could be reduced by funds held in trust and proceeds from sales of the facilities securing the project debt, which is presently not estimable.

MSW I

Agreements dated June 30, 2003 between MSW I and Duke Capital Corporation (the “Duke Agreement”) and the related escrow agreement entered into as of the same date have been terminated effective as of June 14, 2006. MSW I’s liability related to the Duke Agreement has been adjusted to recognize a reduction of an obligation of MSW I and the termination of the excess liability. See Note 4 — Intangible Assets and Goodwill of the Notes to Condensed Consolidated Financial Statements for the adjustment made to the purchase price allocation in connection with the termination of the Duke Agreement.

Note 10.	Employee Compensation and Benefit Plans

Stock Option Plan

MSW I and MSW II

During 2005, the MSW I and MSW II stock plans were cancelled as a result of the Acquisition and there were no stock options or shares of restricted stock outstanding as of December 31, 2005. The employees of MSW I and MSW II are eligible to participate in Covanta’s equity award plans. Certain employees are covered under comparable Covanta long-term incentive plans, which costs are allocated to MSW I and MSW II from Covanta.

On August 11, 2004, the Board of Directors of Covanta ARC Holdings adopted the 2004 Stock Option Plan (the “2004 Plan”), effective January 1, 2004, as further modified on September 16, 2004. The 2004 Plan was designed to link the interests of former officers of Covanta ARC Holdings (who were also the senior management of Covanta Ref-Fuel) to the interests of Covanta ARC Holdings shareholders through the granting of options to purchase stock of Covanta ARC Holdings. Covanta ARC Holdings was at that time a privately held company. During 2004, Covanta ARC Holdings granted 13,199 options to the executive officers of Covanta Ref-Fuel under the 2004 Plan, with a weighted average exercise price per share of $1,189.51.

On January 31, 2005, in conjunction with the Acquisition, the Board of Directors of Covanta ARC Holdings and optionees under the 2004 Plan adopted an Option Modification Agreement (“OMA”). Under the terms of the OMA, immediately prior to the Acquisition, the 2004 Plan was terminated, and on June 24, 2005, a cash payment representing all outstanding options granted or ungranted, but authorized under the terms of the 2004 Plan, together with certain amounts due and anticipated under other long-term compensation plans, was made in the amount of approximately $30.2 million and was recorded as compensation expense prior to the Acquisition.

MSW I and MSW II applied the recognition provisions of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations in accounting for their stock-based compensation plans. No compensation cost was recognized for the 2004 Plan during the period from January 1 through June 24, 2005.


Note 11.	Related Party Transactions

MSW I and MSW II

As a result of the Acquisition, Covanta and its subsidiaries became affiliates of MSW I and MSW II. As of September 30, 2006 and December 31, 2005, MSW I had a net payable to affiliate of $9.5 million and $4.2 million, respectively, and MSW II had a net payable to affiliate of $9.5 million and $4.2 million, respectively, which related to certain costs that were paid on behalf of MSW I and MSW II by their affiliates. The affiliate balances are and will continue to be cash settled, and relate to services in the ordinary course of business.


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

The following discussion addresses the financial condition of MSW Energy Holdings LLC (collectively herein with its subsidiaries “MSW I”) and MSW Energy Holdings II LLC (collectively herein with its subsidiaries “MSW II”) as of September 30, 2006, and its results of operations for the three and nine months ended September 30, 2006, compared with the same periods last year. It should be read in conjunction with the Unaudited Condensed Consolidated Financial Statements and Notes thereto for the period ended September 30, 2006 which is included elsewhere in this quarterly report. Additionally, it should be read in conjunction with the MSW I and MSW II Audited Consolidated Financial Statements and Notes thereto for the year ended December 31, 2005 and Management’s Discussion and Analysis included in their respective Annual Reports on Form 10-K for the year ended December 31, 2005.

The preparation of interim financial statements necessarily relies heavily on estimates. Due to the use of estimates and certain other factors, such as the seasonal nature of portions of the MSW I and MSW II businesses as well as competitive and other market conditions, MSW I and MSW II do not believe that interim results of operations are indicative of full year results of operations. The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts and classification of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.

MSW Energy Finance Co., Inc. (“MSW Energy Finance”), a Delaware corporation and wholly-owned subsidiary of MSW I, was formed in June 2003 solely for the purpose of serving as a co-issuer of the MSW I 8.50% Senior Notes due 2010 and it does not have any operations, assets or revenues. MSW Energy Finance Co. II, Inc. (“MSW Energy Finance II”), a Delaware corporation and wholly-owned subsidiary of MSW II, was formed in August 2003 solely for the purpose of serving as a co-issuer of the MSW II 7.375% Senior Notes due 2010 and it does not have any operations, assets or revenues.

On June 24, 2005, Covanta Holding Corporation (“Covanta”), a Delaware corporation, through its wholly-owned subsidiary, Covanta Energy Corporation (“Covanta Energy”), a Delaware corporation, acquired all of the issued and outstanding shares of capital stock of Covanta ARC Holdings, Inc. (“Covanta ARC Holdings”) (the “Acquisition”). The Acquisition was made pursuant to the terms of a Stock Purchase Agreement, dated as of January 31, 2005 among Covanta, Covanta ARC Holdings and the stockholders of Covanta ARC Holdings. As a result of the Acquisition, Covanta, through Covanta Energy, owns 100% of the voting securities of Covanta ARC Holdings.

Covanta Energy paid approximately $747 million, including transaction costs, for the shares of Covanta ARC Holdings and assumed the consolidated net debt of Covanta ARC Holdings, which was approximately $1.3 billion as of June 24, 2005 ($1.5 billion of consolidated indebtedness net of $0.2 billion of cash and restricted cash). Upon consummation of the Acquisition, a change in ownership occurred, and in accordance with Emerging Issues Task Force (“EITF”) Topic D-97, “Push-Down Accounting” (“EITF D-97”), the MSW I and MSW II financial statements reflect the effects of their change in ownership and the new owner’s basis in the net assets and liabilities acquired. As a result, the statements of operations and the statements of cash flows for the period from January 1, 2005 through June 24, 2005, reflect the results of MSW I and MSW II prior to purchase accounting adjustments and the balance sheet at December 31, 2005, the statements of operations for the three and nine months ended September 30, 2006 and for the period from June 25 through September 30, 2005 and statements of cash flows for the nine months ended September 30, 2006 and for the period from June 25 through September 30, 2005, reflect the impact of the purchase price allocation arising from the Acquisition.

The following chart reflects a simplified ownership structure of MSW I, MSW Energy Finance, MSW II and MSW Energy Finance II. Unless otherwise noted, ownership interests are 100%:

Covanta ARC LLC (“Covanta ARC”), a wholly-owned subsidiary of Covanta Ref-Fuel Holdings LLC (“Covanta Ref-Fuel”) owns partnerships that develop, own and operate waste-to-energy facilities, which combust municipal solid waste and produce energy in the form of electricity and steam. Through such partnerships, Covanta ARC owns or controls six waste-to-energy facilities located in the northeastern United States (the “ARC operating facilities”). The subsidiaries of Covanta ARC that operate the ARC operating facilities (the “ARC operating companies”) derive revenues principally from disposal or tipping fees received for accepting waste and from the sale of electricity and steam produced by the ARC operating facilities.

MSW I and MSW II are organized as holding companies with all of their operations conducted through subsidiaries in the waste and energy services business. As of June 24, 2005, Covanta purchased 100% of the stock of Covanta ARC Holdings. Covanta also conducts its operations through subsidiaries in the waste and energy services business, and the management for MSW I and MSW II, and that of their subsidiaries, is now controlled by Covanta.

MSW I has issued 8.50% Senior Notes due 2010 and MSW II has issued 7.375% Senior Notes due 2010. MSW I and MSW II rely on cash distributions from their subsidiaries in order to pay periodic debt service when due on their respective senior notes. Their ability to pay such debt service is dependent upon the ability of the ARC operating subsidiaries to generate cash flow for distributions, and upon the ability of their intermediate subsidiary, Covanta ARC, to satisfy financial and other covenants applicable to it under their respective debt arrangements. MSW I and MSW II have historically received sufficient cash distributions to pay periodic debt service on their respective senior notes. For additional detail regarding risks attendant to the businesses of the operating subsidiaries of MSW I and MSW II, see “Risk Factors” in Item 1A of the respective MSW I and MSW II Annual Reports on Form 10-K for the year ended December 31, 2005.

MSW I and MSW II quarterly operating income within the same fiscal year typically differs substantially due to seasonal factors, primarily as a result of the timing of scheduled plant maintenance. MSW I and MSW II have typically experienced lower operating income from their projects during the first six months of each year when they conduct their plant maintenance and higher operating income during the second six months of each year.

The following discussion of MSW I and MSW II financial condition and operating results should be read in conjunction with the condensed consolidated financial statements and related notes appearing in this Quarterly

Report on Form 10-Q, and in the respective MSW I and MSW II Annual Reports on Form 10-K for the year ended December 31, 2005.

Results of Operations

The results of operations for MSW I and MSW II for the nine months ended September 30, 2006 are not comparable to their respective results of operations for the nine months ended September 30, 2005, due to the revaluation of each of their respective balance sheets as of June 24, 2005 in connection with the Acquisition. The respective results of operations for MSW I and MSW II for the three months ended September 30, 2006 and 2005 are comparable as both periods have reflected the revaluation of each of their respective balance sheets in connection with the acquisition.

MSW I and MSW II believe that an understanding of their reported results, trends and ongoing performance is enhanced by presenting results on a pro forma basis as if the Acquisition occurred on January 1, 2005. This pro forma supplemental data is presented because MSW I and MSW II believe that it provides a more useful presentation of their financial condition than the data included in their respective historical financial statements. Additionally, these results are presented because MSW I and MSW II believe they may be useful in measuring their respective ability to meet debt service obligations, but they are not necessarily indicative of actual results and should not be considered as an alternative to cash flow from operating activities as a measure of liquidity. However, the pro forma results are equivalent to reported results for the nine months ended September 30, 2006, as there are no pro forma adjustments for this period. The consolidated results of operations for MSW I and MSW II, as reported and where applicable, on a pro forma basis, are summarized in the tables and discussions below. The pro forma reconciliations and description of adjustments are described starting on page 32. The pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the Acquisition had taken place on January 1, 2005.

The results of operations for the period from January 1 through June 24, 2005 and June 25 through September 30, 2005 have been combined for the nine months ended September 30, 2005 for informational and comparative purposes only. It is not appropriate under United States generally accepted accounting principles (“US GAAP”) to combine two different bases of accounting; however, in order to provide a more useful comparison, these periods have been combined in the discussion below.

Comparison of Reported Results for the Three Months Ended September 30, 2006 vs. Reported Results for the Three Months Ended September 30, 2005

Total Operating Revenues. Total operating revenues were $129.1 million for the three months ended September 30, 2006, an increase of $3.9 million when compared to the same period in the prior year. Waste and service revenues increased by $0.8 million due primarily due to higher volumes and higher scrap metal pricing during the three months ended September 30, 2006, compared to the same period in 2005. Electricity and steam sales increased by $3.1 million for the three months ended September 30, 2006, compared to the same period in 2005 due primarily to improved energy pricing and increased production.

Plant Operating Expenses. Plant operating expenses were $45.9 million for the three months ended September 30, 2006, a decrease of $1.1 million when compared to the same period in the prior year. This decrease is attributed to cost reduction initiatives.

Net Interest Expense on Project Debt. Net interest expense on project debt decreased $1.2 million for the three months ended September 30, 2006 primarily as a result of lower project debt balances, as compared to the three months ended September 30, 2005.

General and Administrative Expenses. General and Administrative expenses were $6.4 million for the three months ended September 30, 2006, an increase of $2.7 million when compared to the same period in the prior year. This increase is due primarily to the allocation of costs for support services received from Covanta ARC Holdings, its parent company, which were not allocated in the same quarter of the prior year.

Comparison of Reported Results for the Nine Months Ended September 30, 2006 vs. Combined Results for the Nine Months Ended September 30, 2005

Total Operating Revenues. Total operating revenues were $376.2 million for the nine months ended September 30, 2006, an increase of $13.9 million when compared to the same period in the prior year. Waste and service revenues increased by $6.1 million due primarily to favorable pricing and higher volume during the nine months ended September 30, 2006, compared to the same period in 2005. Electricity and steam sales increased by $7.8 million for the nine months ended September 30, 2006, compared to the same period in 2005 due primarily to improved energy pricing and increased production.

Total Operating Expenses. Total operating expenses were $289.9 million for the nine months ended September 30, 2006, a decrease of $15.1 million when compared to the same period in the prior year. The reduction was primarily attributable to an expense in the three months ended June 30, 2005 of $30.2 million related to payments made to Covanta ARC Holdings’ management, in connection with the Acquisition, which did not occur in the same period of the current year, offset by normal expense escalations.

Operating Income. Total operating income was $86.3 million for the nine months ended September 30, 2006, an increase of $29.0 million from the same period in 2005.

Comparison of Reported Results for the Nine Months Ended September 30, 2006 vs. Pro Forma Results for the Nine Months Ended September 30, 2005

Total Operating Revenues. Total operating revenues were $376.2 million for the nine months ended September 30, 2006, an increase of $12.1 million over the comparable prior year period. Waste and service revenues were $242.3 million for the nine months ended September 30, 2006, an increase of $4.3 million when compared to the same period in 2005. The increase in waste and service revenue was primarily attributable to favorable pricing and higher volumes and higher scrap metal pricing during the nine months ended September 30, 2006 when compared to the same period in 2005. Electricity and steam sales were $133.9 million for the nine months ended September 30, 2006, an increase of $7.8 million compared to the same period in 2005. This increase was primarily attributable to improved energy pricing and increased production in 2006 as compared to the same period in 2005.

due to normal expense escalations, offset by cost reduction initiatives in the current period as compared to the period from the prior year.

Net Interest Expense on Project Debt. Net interest expense on project debt decreased approximately $3.2 million for the nine months ended September 30, 2006 primarily as a result of lower project debt balances, as compared to the nine months ended September 30, 2005.

General and Administrative Expenses. General and Administrative expenses were $19.3 million for the nine months ended September 30, 2006, an increase of $4.3 million when compared to the same period in the prior year. This increase is due primarily to the allocation of costs for support services received from Covanta ARC Holdings, its parent company, which were not allocated in the same period of the prior year.

The increase was primarily due to normal expense escalations, offset by cost reduction initiatives in the current period as compared to the period from the prior year.

General and Administrative Expenses. General and Administrative expenses were $19.2 million for the nine months ended September 30, 2006, an increase of $4.5 million when compared to the same period in the prior year. This increase is due primarily to the allocation of costs for support services received from Covanta ARC Holdings, its parent company, which were not allocated in the same period of the prior year.

Notes to Pro Forma Reconciliations

Pro Forma Assumptions

The unaudited pro forma condensed combined financial statements reflect the following assumptions:


	•	Covanta, through Covanta Energy, purchased 100% of the issued and outstanding shares of Covanta ARC Holdings’ capital stock on January 1, 2005 following the same terms as the Acquisition. As a result of this assumption, each of the respective assets and liabilities of MSW I and MSW II were assumed to be stated at their acquired fair value as of January 1, 2005.

Pro Forma Adjustments

The following is a summary of the pro forma adjustments made:


	•	Waste and service revenues: To record additional revenues prior to June 25, 2005 as a result of conforming debt service revenue recognition to Covanta’s debt service revenue recognition policy, which policy has been implemented for the periods subsequent to June 25, 2005.

	•	Plant operating expenses: To record as rent expense the net impact of the change in the fair value of the lease for the Delaware Valley facility as of January 1, 2005.

	•	Depreciation and amortization expense: To reverse historical depreciation and amortization expense and record pro forma depreciation and amortization expense based on fair values assigned to property, plant and equipment, amortizable intangible assets and waste contract liabilities as part of the Acquisition.

	•	General and administrative expenses: To reverse compensation and related expenses associated with the MSW I and MSW II executives in the periods prior to the Acquisition. Additionally, the expense associated with the MSW I and MSW II headquarters was removed. An estimated allocation of overhead expenses for certain Covanta key senior management, as well as building services was added.

	•	Net interest expense on project debt: To reverse the prior amortization of the project debt and to record the impact of the fair value adjustment as a result of the Acquisition.

Liquidity and Capital Resources

MSW I and MSW II

As of September 30, 2006, the assets of MSW I and MSW II related primarily to their indirect membership interests in the ARC operating facilities. Covanta ARC and the ARC operating facilities have historically generated adequate funds from operations for working capital requirements, capital spending, debt repayments and dividend payouts. Accordingly, MSW I and MSW II’s performance and source of future liquidity will depend solely on cash distributions, if any, from Covanta ARC and the ARC operating facilities. MSW I and MSW II will need to continue to receive sufficient ongoing cash distributions from these entities in order to pay principal and interest on their respective senior notes, however such distributions are not assured. Interest only is payable throughout the term of their respective senior notes with principal and unpaid interest payable at maturity on September 1, 2010.

Sources and Uses of Cash for the Nine Months Ended September 30, 2006

A condensed statement of cash flows follows (unaudited, in thousands of dollars):

Cash and cash equivalents, end of period	$	46,233		$	39,917		$	21,536

Operating Activities

The net cash provided by operating activities was $138.2 million for the nine months ended September 30, 2006, compared to $96.5 million for the combined nine months ended September 30, 2005. The increase in net cash provided by operating activities was primarily attributable to higher earnings in the nine months ended September 30, 2006 compared to the prior year and a payment of $30.2 million made to Covanta ARC Holdings management in the nine months ended September 30, 2005, which did not recur in the current period.

Investing Activities

The net cash used in investing activities was $9.8 million for the nine months ended September 30, 2006, compared to $25.3 million for the combined nine months ended September 30, 2005. Capital expenditures were the primary use of cash from investing activities and were $10.1 million and $27.1 million for the nine months ended September 30, 2006 and the combined nine months ended September 30, 2005, respectively.

Financing Activities

The net cash used in financing activities was $131.1 million for the nine months ended September 30, 2006, compared to $117.6 million for the combined nine months ended September 30, 2005. Cash used in the current period primarily related to $31.8 million of repayments of project debt, a $22.4 million repayment of intermediate debt, distributions of $39.2 million to MSW I’s members, $40.4 million paid to holders of minority interests in consolidated subsidiary. This use of cash was partially offset by a net decrease of $2.7 million to restricted funds held in trust which was used to make project and intermediate debt payments. Cash used in the combined nine months ended September 30, 2005 primarily related to $42.1 million of repayments of project debt, a $10.3 million repayment of intermediate debt, distributions of $23.2 million to MSW I’s members, $41.0 million paid to holders of minority interests in consolidated subsidiary, and a net increase of $1.0 million to restricted funds held in trust which was funded to make project and intermediate debt payments.

Duke Agreement

Agreements dated June 30, 2003 between MSW I and Duke Capital Corporation (the “Duke Agreement”) and the related escrow agreement entered into as of the same date, have been terminated effective as of June 14, 2006.

Debt Covenants

MSW I and MSW II

The indentures under which each of the MSW I and MSW II senior notes were issued contain certain restrictions which will, among other things, prevent MSW I and MSW II each from incurring additional indebtedness, making restricted payments, making investments, selling assets or merging with other companies, subject to certain exceptions. Each of the MSW I and MSW II senior notes are redeemable with the payment of certain stated make whole amounts before September 1, 2007 and, thereafter, at the face amount of such senior notes, plus accrued interest. Restricted payments are not permitted unless certain ratio covenants based on the proportionate ownership of Covanta Ref-Fuel have been met. As of September 30, 2006, MSW I and MSW II were in compliance with all of their respective debt covenants.

Critical Accounting Policies

MSW I and MSW II

In preparing their respective condensed consolidated financial statements in accordance with US GAAP, MSW I and MSW II are required to use judgment in making estimates and assumptions that affect the amounts reported in their respective financial statements and related notes. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Many of the critical accounting policies of MSW I and MSW II are those subject to significant judgments and uncertainties which could potentially result in materially different results under different conditions and assumptions. Future events rarely develop exactly as forecast, and the best estimates routinely require adjustment. See the Discussion of Critical Accounting Policies in Item 7 of the respective MSW I and MSW II Annual Reports on Form 10-K for the year ended December 31, 2005.

The item has been intentionally omitted as allowed under General Instruction H(2)(c) on Form 10-Q.


ITEM 4.	*CONTROLS AND PROCEDURES*

MSW I and MSW II

As of September 30, 2006, the management of each of MSW I and MSW II, with the participation of the Chief Executive Officer and Chief Financial Officer of each respective company, have reviewed and evaluated the effectiveness of their respective disclosure controls and procedures, as required by Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934. The disclosure controls and procedures for MSW I and MSW II are designed to reasonably assure that information required to be disclosed in reports they file or submit under the Securities Exchange Act of 1934 is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer of each respective company, as appropriate to allow timely decisions regarding disclosure and is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Accordingly, management of each of MSW I and MSW II have concluded that the disclosure controls and procedures for each of MSW I and MSW II were effective as of September 30, 2006.

Management of MSW I and MSW II, with the participation of its Chief Executive Officer and Chief Financial Officer of each respective company, believes that its disclosure controls and procedures are effective to provide such reasonable assurance.

The management of MSW I and MSW II, including the Chief Executive Officer and Chief Financial Officer of each respective company, believe that any disclosure controls and procedures or internal controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, they cannot provide absolute assurance that all control issues and instances of fraud, if any, have been prevented or detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by unauthorized override of the control. The design of any systems of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Accordingly, because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.
