Basis of Presentation


1.	Basis of Presentation

The financial statements presented in this report represent the consolidation of Waste Management, Inc., a Delaware corporation; Waste Management’s wholly-owned and majority-owned subsidiaries; and certain variable interest entities for which Waste Management or its subsidiaries are the primary beneficiary. Waste Management is a holding company and all operations are conducted by its subsidiaries. When the terms “the Company,” “we,” “us” or “our” are used in this document, those terms refer to Waste Management, Inc., its consolidated subsidiaries and consolidated variable interest entities. When we use the term “WMI,” we are referring only to Waste Management, Inc., the parent holding company.

We manage and evaluate our principal operations through five Groups. Our four geographic operating Groups, which include our Eastern, Midwest, Southern and Western Groups, provide collection, transfer, recycling and disposal services. Our fifth operating group is the Wheelabrator Group, which provides waste-to-energy services. We also provide additional services that are not managed through our five Groups, which are presented in this report as “Other.” Additional information related to our segments can be found in Note 10.

The Condensed Consolidated Financial Statements as of and for the three months ended March 31, 2010 and 2009 are unaudited. In the opinion of management, these financial statements include all adjustments, which, unless otherwise disclosed, are of a normal recurring nature, necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. The results for interim periods are not necessarily indicative of results for the entire year. The financial statements presented herein should be read in connection with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2009.

In preparing our financial statements, we make numerous estimates and assumptions that affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with a high degree of precision from data available or simply cannot be readily calculated based on generally accepted methods. In some cases, these estimates are particularly difficult to determine and we must exercise significant judgment. In preparing our financial statements, the most difficult, subjective and complex estimates and the assumptions that deal with the greatest amount of uncertainty relate to our accounting for landfills, environmental remediation liabilities, asset impairments, and self-insurance reserves and recoveries. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements.

Subsequent events have been evaluated through the date and time the financial statements were issued. No material subsequent events have occurred since March 31, 2010 that required recognition or disclosure in our current period financial statements.

Adoption of New Accounting Standards

Consolidation of Variable Interest Entities — In June 2009, the FASB issued revised authoritative guidance associated with the consolidation of variable interest entities. The revised guidance replaced the previous quantitative-based assessment for determining which enterprise has a controlling interest in a variable interest entity with an approach that is now primarily qualitative. This qualitative approach focuses on identifying the enterprise that has (i) the power to direct the activities of the variable interest entity that can most significantly impact the entity’s performance; and (ii) the obligation to absorb losses and the right to receive benefits from the entity that could potentially be significant to the variable interest entity. The revised guidance also requires an ongoing assessment of whether an enterprise is the primary beneficiary of a variable interest entity rather than a reassessment only upon the occurrence of specific events.

As a result of our implementation of this guidance, effective January 1, 2010, we deconsolidated certain closure, post-closure and environmental remediation trusts for which power over significant activities is shared. Our financial interests in these entities are discussed below. The deconsolidation of these trusts has not materially affected our financial position, results of operations or cash flows during the periods presented.

Following is a description of our financial interests in variable interest entities that we consider significant, including (i) those for which we have determined that we are the primary beneficiary of the entities and, therefore, have continued to consolidate the entities into our financial statements; and (ii) those that represent a significant interest in an unconsolidated entity.

Consolidated Variable Interest Entities

Waste-to-Energy LLCs — In June 2000, two limited liability companies were established to purchase interests in existing leveraged lease financings at three waste-to-energy facilities that we lease, operate and maintain. We own a 0.5% interest in one of the LLCs (“LLC I”) and a 0.25% interest in the second LLC (“LLC II”). John Hancock Life Insurance Company owns 99.5% of LLC I and 99.75% of LLC II is owned by LLC I and the CIT Group. In 2000, Hancock and CIT made an initial investment of $167 million in the LLCs, which was used to purchase the three waste-to-energy facilities and assume the seller’s indebtedness.

Income, losses and cash flows of the LLCs are allocated to the members based on their initial capital account balances until Hancock and CIT achieve targeted returns; thereafter, we will receive 80% of the earnings of each of the LLCs and Hancock and CIT will be allocated the remaining 20% proportionate to their respective equity interests. All capital allocations made through March 31, 2010 have been based on initial capital account balances as the target returns have not yet been achieved.

Our obligations associated with our interests in the LLCs are primarily related to the lease of the facilities. In addition to our minimum lease payment obligations, we are required to make cash payments to the LLCs for differences between fair market rents and our minimum lease payments. We may also be required under certain circumstances to make capital contributions to the LLCs based on differences between the fair market value of the facilities and defined termination values as provided for in the underlying lease agreements, although we believe the likelihood of the occurrence of these circumstances is remote.

We have determined that we are the primary beneficiary of the LLCs because (i) all of the equity owners of the LLCs are considered related parties for purposes of applying this accounting guidance; (ii) the equity owners share power over the significant activities of the LLCs; and (iii) we are the entity within the related party group whose activities are most closely associated with the LLCs.

As of March 31, 2010, our Condensed Consolidated Balance Sheet includes $328 million of net property and equipment associated with the LLCs’ waste-to-energy facilities and $239 million in noncontrolling interests associated with Hancock’s and CIT’s interests in the LLCs. As of March 31, 2010, all debt obligations of the LLCs have been paid in full and, therefore, the LLCs have no liabilities. We recognized expense of $13 million during both the three months ended March 31, 2010 and the three months ended March 31, 2009 for Hancock’s and CIT’s noncontrolling interests in the LLCs’ earnings. The LLCs’ earnings relate to the rental income generated from leasing the facilities to our subsidiaries, reduced by depreciation expense. The LLCs’ rental income is eliminated in WMI’s consolidation.

Significant Unconsolidated Variable Interest Entities

Trusts for Closure, Post-Closure or Environmental Remediation Obligations — We have significant financial interests in trust funds that were created to settle certain of our closure, post-closure or environmental remediation obligations. We have determined that, under the current guidance, we are not the primary beneficiary of certain of these trust funds because power over the trusts’ significant activities is shared.

The deconsolidation of these variable interest entities as of January 1, 2010 reduced our restricted trust and escrow accounts by $109 million; our long-term receivables by $27 million; and noncontrolling interests by $31 million. Beginning in 2010, our interests in these trust funds have been accounted for as investments in unconsolidated entities, which had a fair value of $105 million as of January 1, 2010 and $107 million as of March 31, 2010. We continue to reflect our interests in the unrealized gains and losses on marketable securities held by these trusts as a component of accumulated other comprehensive income. The deconsolidation of these variable interest entities has not materially affected our financial position or results of operations for the periods presented.

As the party with primary responsibility to fund the related closure, post-closure or environmental remediation activities, we are exposed to risk of loss as a result of potential changes in the fair value of the trusts assets. The fair value of trust assets can fluctuate due to (i) changes in the market value of the investments held by the trusts; and (ii) credit risk associated with trust receivables. Although we are exposed to changes in the fair value of the trust assets, we currently expect the trust funds to continue to meet the statutory requirements for which they were established.

At several of our landfills, we provide financial assurance by depositing cash into restricted trust funds or escrow accounts for purposes of settling closure, post-closure and environmental remediation obligations. Generally, these trust funds are established to comply with statutory requirements and operating agreements and we are the sole beneficiary of the restricted balances. However, certain of the funds have been established for the benefit of both the Company and the host community in which we operate.

The fair value of trust funds and escrow accounts for which we are the sole beneficiary was $123 million at March 31, 2010. As discussed in Note 1, effective January 1, 2010, we deconsolidated the trusts for which power over significant activities of the trust is shared, which reduced our restricted trust and escrow accounts by $109 million as of January 1, 2010. Beginning in 2010, our interest in these trust funds has been accounted for as investments in unconsolidated entities. The fair value of our investment in these entities was $107 million as of March 31, 2010. These amounts are included as long-term “Other assets” in our Condensed Consolidated Balance Sheet.

Debt Classification

As of March 31, 2010, we had $1,108 million of debt maturing within twelve months. We have classified $476 million of these borrowings as long-term as of March 31, 2010 based on our intent and ability to refinance these borrowings on a long-term basis.

Net Debt Repayments

During the three months ended March 31, 2010, we repaid $35 million of our tax-exempt bonds, $9 million of advances outstanding under our Canadian credit facility and $11 million of capital leases and other debt with available cash.

Letter of Credit Facilities

In addition to our $2.4 billion revolving credit facility, we had an aggregate capacity of $580 million for letters of credit under a $175 million letter of credit facility expiring June 2010; a $105 million letter of credit facility expiring June 2013; a $100 million letter of credit facility expiring December 2014; and a $200 million letter of credit facility expiring June 2015. These facilities provide for commitments from counterparties to issue letters of credit at our request. To the extent there are any unreimbursed draws on letters of credit under these facilities, the drawn amounts convert to term loans under the respective facility. Through March 31, 2010, we had not experienced any unreimbursed draws on letters of credit under these facilities.

As of March 31, 2010, no borrowings were outstanding under our revolving credit facility or these letter of credit facilities. We currently have $1,447 million of letters of credit outstanding under our revolving credit facility and an aggregate of $572 million of letters of credit outstanding under our letter of credit facilities.

Interest Rate Derivatives

Interest Rate Swaps

We use interest rate swaps to maintain a portion of our debt obligations at variable market interest rates. As of March 31, 2010, the outstanding principal of our fixed-rate senior notes was approximately $5.4 billion. The interest payments on $1.1 billion, or 20%, of these senior notes have been swapped to variable interest rates to protect the debt against changes in fair value due to changes in benchmark interest rates.

We have designated our interest rate swaps as fair value hedges of our fixed-rate senior notes. Fair value hedge accounting for interest rate swap contracts increased the carrying value of debt instruments by $87 million as of March 31, 2010 and $91 million as of December 31, 2009.

Gains or losses on the derivatives as well as the offsetting losses or gains on the hedged items attributable to our interest rate swaps are recognized in current earnings. We include gains and losses on our interest rate swaps as adjustments to interest expense, which is the same financial statement line item where offsetting gains and losses on the related hedged items are recorded. The following table summarizes the impact of changes in the fair value of our interest rate swaps and the underlying hedged items on our results of operations (in millions):


Three Months Ended		Statement of Operations		Gain (Loss) on			Gain (Loss) on
March 31,		Classification		Swap			Fixed-Rate Debt

	2010		Interest expense	$	1		$	(1	)
	2009		Interest expense	$	(9	)	$	9

We also recognize the impacts of (i) net periodic settlements of current interest on our active interest rate swaps and (ii) the amortization of previously terminated interest rate swap agreements as adjustments to interest expense. The following table summarizes the impact of periodic settlements of active swap agreements and the impact of terminated swap agreements on our results of operations (in millions):


	Three Months
Reductions to Interest Expense Due to	Ended March 31,
Hedge Accounting for Interest Rate Swaps	2010		2009

Periodic settlements of active swap agreements(a)	$	10	$	12
Terminated swap agreements(b)		5		6

	$	15	$	18


(a)		These amounts represent the net of our periodic variable-rate interest obligations and the swap counterparties’ fixed-rate interest obligations. Our variable-rate obligations are based on a spread from the three-month LIBOR.

(b)		The amortization to interest expense of terminated swap agreements has decreased due to the maturity of certain previously hedged senior notes.

Treasury Rate Locks

During the third quarter of 2009, we entered into Treasury rate locks with a total notional amount of $200 million to hedge the risk of changes in semi-annual interest payments for a portion of the senior notes that the Company plans to issue late in the second quarter of 2010. We have designated our Treasury rate lock derivatives as cash flow hedges. As of March 31, 2010, the fair value of these interest rate derivatives is comprised of $1 million of current assets. We recognized pre-tax and after-tax losses of $3 million and $2 million, respectively, to other comprehensive income for changes in their fair value during the three months ended March 31, 2010. There was no significant ineffectiveness associated with these hedges during the three months ended March 31, 2010.

Our “Accumulated other comprehensive income” also includes deferred losses, net of taxes, of $15 million as of March 31, 2010 and $16 million as of December 31, 2009 related to Treasury rate locks that had been executed in previous years in anticipation of senior note issuances. As these instruments also were designated as cash flow hedges, the deferred losses are being reclassified to earnings over the term of the hedged cash flows, which extend through 2032.

The Company currently expects to issue fixed-rate debt in March 2011, November 2012 and March 2014 and has executed forward-starting interest rate swaps for these anticipated debt issuances with notional amounts of $150 million, $200 million and $175 million, respectively. We entered into the forward-starting interest rate swaps during the fourth quarter of 2009 to hedge the risk of changes in the anticipated semi-annual interest payments due to fluctuations in the forward ten-year LIBOR swap rate. Each of the forward-starting swaps has an effective date of the anticipated date of debt issuance and a term of ten years.

We have designated our forward-starting interest rate swaps as cash flow hedges. As of March 31, 2010, the fair value of these interest rate derivatives is comprised of $4 million of long-term assets. We recognized pre-tax and after-tax losses of $5 million and $3 million, respectively, to other comprehensive income for changes in the fair value of our forward-starting interest rate swaps during the three months ended March 31, 2010. There was no significant ineffectiveness associated with these hedges during the three months ended March 31, 2010.

Credit-Risk Features

Certain of our interest rate derivative instruments contain provisions related to the Company’s credit ratings. If the Company’s credit rating were to fall below investment grade, the counterparties have the ability to cancel the derivative agreements and request immediate payment of any net liability positions. We do not have any derivative instruments with credit-risk-related contingent features that are in a net liability position at March 31, 2010.

Foreign Exchange Derivatives

We use foreign currency exchange rate derivatives to hedge our exposure to changes in exchange rates for anticipated intercompany cash transactions between WM Holdings and its Canadian subsidiaries. As of March 31, 2010, we have foreign currency forward contracts outstanding for all of the anticipated cash flows associated with a debt arrangement between these wholly-owned subsidiaries. The hedged cash flows include C$370 million of principal, which is scheduled for repayment on December 31, 2010, and C$22 million of interest payments scheduled for December 31, 2010. We have designated our foreign currency derivatives as cash flow hedges.

Gains or losses on the derivatives and the offsetting losses or gains on the hedged items attributable to foreign currency exchange risk are recognized in current earnings. We include gains and losses on our foreign currency forward contracts as adjustments to other income and expense, which is the same financial statement line item where offsetting gains and losses on the related hedged items are recorded. The following table summarizes the pre-tax impacts of our foreign currency cash flow derivatives on our results of operations and comprehensive income (in millions):


		Amount of Gain or				Amount of Gain or
		(Loss) Recognized				(Loss) Reclassified
		in OCI on				from AOCI into

	2010	$	(12	)	Other income (expense)	$	(12	)
	2009	$	12		Other income (expense)	$	12

The above table represents the impacts of our foreign exchange contracts on a pre-tax basis. Amounts reported in other comprehensive income and accumulated other comprehensive income are reported net of tax. Adjustments to other comprehensive income for changes in the fair value of our foreign currency cash flow hedges resulted in the recognition of an after-tax loss of $7 million during the three months ended March 31, 2010 and an after-tax gain of $8 million during the three months ended March 31, 2009. Adjustments for the reclassification of gains or (losses) from accumulated other comprehensive income into income were $(8) million during the three months ended March 31, 2010 and $7 million during the three months ended March 31, 2009. There was no significant ineffectiveness associated with these hedges during the three months ended March 31, 2010 or 2009.

Electricity Commodity Derivatives

During the first quarter of 2010, we entered into “receive fixed, pay variable” electricity swaps to mitigate the variability in our revenues and cash flows caused by fluctuations in the market prices for electricity. The swaps collectively hedge 568,200 megawatt hours over either two- or nine-month periods. The electricity swaps in place are expected to hedge approximately 40% of our Wheelabrator Group’s 2010 merchant electricity sales. We have designated our electricity swaps as cash flow hedges. As of March 31, 2010, the fair value of these derivatives is comprised of $1 million of current assets. We recognized pre-tax and after-tax gains of approximately $1 million to other comprehensive income for changes in their fair value during the three months ended March 31, 2010. There was no significant ineffectiveness associated with these hedges during the three months ended March 31, 2010.

5.	Income Taxes

Our effective tax rate for the three months ended March 31, 2010 was 36.6% compared with 37.2% for the comparable prior-year period. The differences between federal income taxes computed at the federal statutory rate and reported income taxes for the three-month periods ended March 31, 2010 and 2009 were primarily due to the unfavorable impact of state and local income taxes. We evaluate our effective tax rate at each interim period and adjust it accordingly as facts and circumstances warrant.

The Patient Protection and Affordable Care Act, which was signed into law in March 2010, includes a provision that eliminates the tax deductibility of retiree health care costs to the extent that retiree prescription drug benefits are reimbursed under Medicare Part D coverage. Although this provision of the Act does not take effect until 2013, we were required to recognize the full accounting impact of the change in law on our deferred tax assets during the first quarter of 2010, the period in which the law was enacted. The remeasurement of our deferred tax assets did not affect our financial position or results of operations as of and for the three months ended March 31, 2010.

Commitments and Contingencies

Commitments and Contingencies [Abstract]

Commitments and Contingencies


8.	Commitments and Contingencies

Financial instruments — We have obtained letters of credit, performance bonds and insurance policies and have established trust funds and issued financial guarantees to support tax-exempt bonds, contracts, performance of landfill closure and post-closure requirements, environmental remediation, and other obligations. Letters of credit generally are supported by our revolving credit facility and other credit facilities established for that purpose. We obtain surety bonds and insurance policies from an entity in which we have a noncontrolling financial interest. We also obtain insurance from a wholly-owned insurance company, the sole business of which is to issue policies for us. In those instances where our use of financial assurance from entities we own or have financial interests in is not allowed, we generally have available alternative financial assurance mechanisms.

Management does not expect that any claims against or draws on these instruments would have a material adverse effect on our consolidated financial statements. We have not experienced any unmanageable difficulty in obtaining the required financial assurance instruments for our current operations. In an ongoing effort to mitigate risks of future cost increases and reductions in available capacity, we continue to evaluate various options to access cost-effective sources of financial assurance.

Insurance — We carry insurance coverage for protection of our assets and operations from certain risks including automobile liability, general liability, real and personal property, workers’ compensation, directors’ and officers’ liability, pollution legal liability and other coverages we believe are customary to the industry. Our exposure to loss for insurance claims is generally limited to the per incident deductible under the related insurance policy. Our exposure, however, could increase if our insurers were unable to meet their commitments on a timely basis.

We have retained a significant portion of the risks related to our automobile, general liability and workers’ compensation insurance programs. For our self-insured retentions, the exposure for unpaid claims and associated expenses, including incurred but not reported losses, is based on an actuarial valuation and internal estimates. The estimated accruals for these liabilities could be affected if future occurrences or loss development significantly differ from the assumptions used. We do not expect the impact of any known casualty, property, environmental or other contingency to have a material impact on our financial condition, results of operations or cash flows.

Purchase Commitments — We continue to focus on the expansion of our waste-to-energy business and are actively pursuing various projects in the United States and internationally. As of December 31, 2009, we had a commitment to purchase a 40% equity investment in Shanghai Environment Group (“SEG”), a subsidiary of Shanghai Chengtou Holding Co., Ltd. During the first quarter of 2010, the Ministry of Commerce of the People’s Republic of China approved the transaction and we paid $142 million for our investment. As a joint venture partner in SEG, we will participate in the operation and management of waste-to-energy and other waste services in the Chinese market. SEG will also focus on building new waste-to-energy facilities in China.

Additionally, our acquisition of a waste-to-energy facility in Portsmouth, Virginia has been approved by both the Southeastern Public Service Authority of Virginia, or SPSA, and the Virginia Resources Authority. We currently expect the acquisition to be completed in April of 2010. The expected purchase price for the facility is approximately $150 million.

Guarantees — In the ordinary course of our business, WMI and WM Holdings enter into guarantee agreements associated with their subsidiaries’ operations. Additionally, WMI and WM Holdings have each guaranteed all of the senior debt of the other entity. No additional liabilities have been recorded for these intercompany guarantees because all of the underlying obligations are reflected in our Condensed Consolidated Balance Sheets.

We also have guaranteed the obligations of, and provided indemnification to, third parties in the ordinary course of business. Guarantee agreements outstanding as of March 31, 2010 include (i) guarantees of unconsolidated entities’ financial obligations maturing through 2020 for maximum future payments of $9 million; and (ii) agreements guaranteeing the market value of homeowners’ properties adjacent to or near certain of our landfills. Our indemnification obligations generally arise in divestitures and provide that we will be responsible for liabilities associated with our operations for events that occurred prior to the sale of the operations. Additionally, under certain of our acquisition agreements, we have provided for additional consideration to be paid to the sellers if established financial targets are achieved post-closing. We have recognized liabilities for these contingent obligations based on an estimate of the fair value of these contingencies at the time of acquisition. Contingent obligations related to indemnifications arising from our divestitures and contingent consideration provided for by our acquisitions are not expected to be material to our financial position, results of operations or cash flows.

Environmental matters — A significant portion of our operating costs and capital expenditures could be characterized as costs of environmental protection, as we are subject to an array of laws and regulations relating to the protection of the environment. Under current laws and regulations, we may have liabilities for environmental damage caused by our operations, or for damage caused by conditions that existed before we acquired a site. In addition to remediation activity required by state or local authorities, such liabilities include potentially responsible party, or PRP, investigations. The costs associated with these liabilities can include settlements, certain legal and consultant fees, as well as incremental internal and external costs directly associated with site investigation and clean-up.

Estimating our degree of responsibility for remediation is inherently difficult. Determining the method and ultimate cost of remediation requires that a number of assumptions be made. There can sometimes be a range of reasonable estimates of the costs associated with the likely remedy of a site. In these cases, we use the amount within the range that constitutes our best estimate. If no amount within a range appears to be a better estimate than any other, we use the amount that is the low end of such range. If we used the high ends of such ranges, our aggregate potential liability would be approximately $150 million higher than the $257 million recorded in the Condensed Consolidated Financial Statements as of March 31, 2010. Our ongoing review of our remediation liabilities could result in revisions to our accruals that could cause upward or downward adjustments to income from operations. These adjustments could be material in any given period.

As of March 31, 2010, we had been notified that we are a PRP in connection with 74 locations listed on the EPA’s National Priorities List, or NPL. Of the 74 sites at which claims have been made against us, 16 are sites we own. Each of the NPL sites we own was initially developed by others as a landfill disposal facility. At each of these facilities, we are working in conjunction with the government to characterize or remediate identified site problems, and we have either agreed with other legally liable parties on an arrangement for sharing the costs of remediation or are working toward a cost-sharing agreement. We generally expect to receive any amounts due from other participating parties at or near the time that we make the remedial expenditures. The other 58 NPL sites, which we do not own, are at various procedural stages under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, known as CERCLA or Superfund.

The majority of these proceedings involve allegations that certain of our subsidiaries (or their predecessors) transported hazardous substances to the sites, often prior to our acquisition of these subsidiaries. CERCLA generally provides for liability for those parties owning, operating, transporting to or disposing at the sites. Proceedings arising under Superfund typically involve numerous waste generators and other waste transportation and disposal companies and seek to allocate or recover costs associated with site investigation and remediation, which costs could be substantial and could have a material adverse effect on our consolidated financial statements. At some of the sites at which we have been identified as a PRP, our liability is well defined as a consequence of a governmental decision and an agreement among liable parties as to the share each will pay for implementing that remedy. At other sites, where no remedy has been selected or the liable parties have been unable to agree on an appropriate allocation, our future costs are uncertain.

Litigation — In April 2002, two former participants in the ERISA plans of Waste Management Holdings, Inc., a wholly-owned subsidiary we acquired in 1998 (“WM Holdings”), filed a lawsuit in the U.S. District Court for the District of Columbia in a case entitled William S. Harris, et al. v. James E. Koenig, et al. The lawsuit named as defendants WM Holdings; the members of WM Holdings’ Board of Directors prior to July 1998; the administrative and investment committees of WM Holdings’ ERISA plans and their individual members; WMI’s retirement savings plan; the investment committees of WMI’s plan and its individual members; and State Street Bank & Trust, the trustee and investment manager of the ERISA plans. The lawsuit attempts to increase the recovery of a class of ERISA plan participants based on allegations related to both the events alleged in, and the settlements relating to, the securities class action against WM Holdings that was settled in 1998 and the securities class action against WMI that was settled in 2001. The defendants filed motions to dismiss the complaints on the pleadings, and the Court granted in part and denied in part the defendants’ motions in the first quarter of 2009. However, in December 2009, the Court granted the plaintiffs’ motion for leave to file a fourth amended complaint to overcome the dismissal of certain complaints and motion for leave to file a substitute fourth amended complaint to add two new claims. Each of Mr. Pope, Mr. Rothmeier and Ms. San Juan Cafferty, members of our Board of Directors, was a member of the WM Holdings’ Board of Directors and therefore is a named defendant in these actions, as is Mr. Simpson, our Chief Financial Officer, by virtue of his membership on the WMI ERISA plan Investment Committee at that time. All of the defendants intend to continue to defend themselves vigorously.

There are two separate wage and hour lawsuits pending against certain of our subsidiaries in California, each seeking class certification. The actions were coordinated to proceed in San Diego County. Both lawsuits make the same general allegations that the defendants failed to comply with certain California wage and hour laws, including allegedly failing to provide meal and rest periods, and failing to properly pay hourly and overtime wages. We deny the claims and intend to continue to vigorously defend these matters. Given the inherent uncertainties of litigation, the ultimate outcome cannot be predicted at this time, nor can possible damages, if any, be reasonably estimated.

From time to time, we also are named as defendants in personal injury and property damage lawsuits, including purported class actions, on the basis of having owned, operated or transported waste to a disposal facility that is alleged to have contaminated the environment or, in certain cases, on the basis of having conducted environmental remediation activities at sites. Some of the lawsuits may seek to have us pay the costs of monitoring of allegedly affected sites and health care examinations of allegedly affected persons for a substantial period of time even where no actual damage is proven. While we believe we have meritorious defenses to these lawsuits, the ultimate resolution is often substantially uncertain due to the difficulty of determining the cause, extent and impact of alleged contamination (which may have occurred over a long period of time), the potential for successive groups of complainants to emerge, the diversity of the individual plaintiffs’ circumstances, and the potential contribution or indemnification obligations of co-defendants or other third parties, among other factors.

As a large company with operations across the United States and Canada, we are subject to various proceedings, lawsuits, disputes and claims arising in the ordinary course of our business. Many of these actions raise complex factual and legal issues and are subject to uncertainties. Actions filed against us include commercial, customer, and employment-related claims, including purported class action lawsuits related to our customer service agreements and purported class actions involving federal and state wage and hour and other laws. The plaintiffs in some actions seek unspecified damages or injunctive relief, or both. These actions are in various procedural stages, and some are covered in part by insurance. We currently do not believe that any such actions will ultimately have a material adverse impact on our consolidated financial statements.

WMI’s charter and bylaws require indemnification of its officers and directors if statutory standards of conduct have been met and allow the advancement of expenses to these individuals upon receipt of an undertaking by the individuals to repay all expenses if it is ultimately determined that they did not meet the required standards of conduct. Additionally, WMI has entered into separate indemnification agreements with each of the members of its Board of Directors as well as its Chief Executive Officer, its President and its Chief Financial Officer. The Company may incur substantial expenses in connection with the fulfillment of its advancement of costs and indemnification obligations in connection with current actions involving former officers of the Company or its subsidiaries, including the Harris lawsuit mentioned above, or other actions or proceedings that may be brought against its former or current officers, directors and employees.

In March 2008, we filed a lawsuit in state district court in Harris County, Texas against SAP AG and SAP America, Inc. The lawsuit related to our 2005 software license from SAP for a waste and recycling revenue management system and SAP’s implementation of the software. In April 2010, we settled the lawsuit, receiving a one-time cash payment, and all parties dismissed their claims with prejudice.

Item 103 of the SEC’s Regulation S-K requires disclosure of certain environmental matters when a governmental authority is a party to the proceedings and the proceedings involve potential monetary sanctions that we reasonably believe could exceed $100,000. The following matter pending as of March 31, 2010 is disclosed in accordance with that requirement:

On April 4, 2006, the EPA issued a Finding and Notice of Violation (“FNOV”) to Waste Management of Hawaii, Inc., an indirect wholly-owned subsidiary of WMI, and to the City and County of Honolulu for alleged violations of the federal Clean Air Act, based on alleged failure to submit certain reports and design plans required by the EPA, and the failure to begin and timely complete the installation of a gas collection and control system for the Waimanalo Gulch Sanitary Landfill on Oahu. The FNOV did not propose a penalty amount and the parties have been in confidential settlement negotiations. Pursuant to an indemnity agreement, any penalty assessed will be paid by the Company, and not by the City and County of Honolulu.

Multi-Employer, Defined Benefit Pension Plans — Over 20% of our workforce is covered by collective bargaining agreements, which are with various union locals across the United States. As a result of some of these agreements, certain of our subsidiaries are participating employers in a number of trustee-managed multi-employer, defined benefit pension plans for the affected employees. One of the multi-employer pension plans in which we participate is the Central States Southeast and Southwest Areas Pension Plan (“Central States Pension Plan”), which has reported that it adopted a rehabilitation plan as a result of its actuarial certification for the plan year beginning January 1, 2008. The Central States Pension Plan is in “critical status,” as defined by the Pension Protection Act of 2006.

In connection with our ongoing re-negotiation of various collective bargaining agreements, we may discuss and negotiate for the complete or partial withdrawal from one or more of these pension plans. In the first quarter of 2010, we recognized a $28 million charge to “Operating” expenses for the agreed-upon withdrawals of three bargaining units from the Central States Pension Plan in connection with our negotiations of those units’ agreements. We do not believe that our withdrawals from multi-employer plans, individually or in the aggregate, will have a material adverse effect on our financial condition or liquidity. However, depending on the number of employees withdrawn in any future period and the financial condition of the multi-employer plans at the time of withdrawal, such withdrawals could materially affect our results of operations in the period of the withdrawal.

Tax Matters — We are currently in the examination phase of IRS audits for the tax years 2009 and 2010 and expect these audits to be completed within the next nine and 21 months, respectively. We participate in the IRS’s Compliance Assurance Program, which means we work with the IRS throughout the year in order to resolve any material issues prior to the filing of our year-end tax return. We are also currently undergoing audits by various state and local jurisdictions that date back to 1999 and examinations associated with Canada that date back to 1998. To provide for certain potential tax exposures, we maintain a liability for unrecognized tax benefits, the balance of which management believes is adequate. Results of audit assessments by taxing authorities are not currently expected to have a material adverse impact on our results of operations or cash flows.

Restructuring


9.	Restructuring

In January 2009, we took steps to streamline our organization by (i) consolidating many of our Market Areas; (ii) integrating the management of our recycling operations with the remainder of our solid waste business; and (iii) realigning our corporate organization with this new structure in order to provide support functions more efficiently.

This reorganization eliminated over 1,500 employee positions throughout the Company. During the three months ended March 31, 2009, we recognized $38 million of pre-tax restructuring charges associated with this reorganization, of which $36 million were related to employee severance and benefit costs. During the remainder of 2009, we incurred an additional $12 million of pre-tax restructuring charges associated with this reorganization, of which $5 million were related to employee severance and benefit costs. The remaining charges were primarily related to operating lease obligations for property that will no longer be utilized. The following table summarizes the charges recognized for this restructuring by each of our current reportable segments and our Corporate and Other organizations for the three months ended March 31, 2009 (in millions):

We currently manage and evaluate our operations primarily through our Eastern, Midwest, Southern, Western and Wheelabrator Groups. These five Groups are presented below as our reportable segments. Our segments provide integrated waste management services consisting of collection, disposal (solid waste and hazardous waste landfills), transfer, waste-to-energy facilities and independent power production plants that are managed by Wheelabrator, recycling services and other services to commercial, industrial, municipal and residential customers throughout the United States and in Puerto Rico and Canada. The operations not managed through our five operating Groups are presented herein as “Other.”

Fluctuations in our operating results may be caused by many factors, including period-to-period changes in the relative contribution of revenue by each line of business and operating segment and by general economic conditions. In addition, our revenues and income from operations typically reflect seasonal patterns. Our operating revenues tend to be somewhat higher in the summer months, primarily due to the traditional seasonal increase in the volume of construction and demolition waste. The volumes of industrial and residential waste in certain regions where we operate also tend to increase during the summer months. Our second and third quarter revenues and results of operations typically reflect these seasonal trends.

Additionally, certain destructive weather conditions that tend to occur during the second half of the year, such as hurricanes typically experienced by our Southern Group, can actually increase our revenues in the areas affected. However, for several reasons, including significant mobilization costs, such revenue often generates earnings at comparatively lower margins. Certain weather conditions, including severe winter storms, may result in the temporary suspension of our operations, which can significantly affect the operating results of the affected regions. The operating results of our first quarter also often reflect higher repair and maintenance expenses because we rely on the slower winter months, when waste flows are generally lower, to perform scheduled maintenance at our waste-to-energy facilities.

From time to time, the operating results of our reportable segments are significantly affected by unusual or infrequent transactions or events. During the first quarter of 2010, our Midwest Group recognized a $28 million charge as a result of bargaining unit employees in Michigan and Ohio agreeing to our proposal to withdraw them from an under-funded multi-employer pension plan. Refer to Note 8 for additional information related to our participation in multi-employer pension plans. Further, as disclosed in Note 9, the income from operations of each of our geographic Groups for the three months ended March 31, 2009 was affected by our January 2009 reorganization.

11.	(Income) Expense from Divestitures, Asset Impairments and Unusual Items

Through December 31, 2008, we had capitalized $70 million of accumulated costs associated with the development of a new waste and recycling revenue management system. A significant portion of these costs was specifically associated with the purchase of a license for waste and recycling revenue management software and the efforts required to develop and configure that software for our use. After a failed pilot implementation of the software in one of our smallest Market Areas, the development efforts associated with the revenue management system were suspended in 2007. During 2009, we determined to enhance and improve our existing revenue management system and not pursue alternatives associated with the development and implementation of the licensed software. Accordingly, in 2009, we recognized a non-cash charge of $51 million, $49 million of which was recognized during the first quarter of 2009 and $2 million of which was recognized during the fourth quarter of 2009 for the abandonment of the licensed software. Refer to Note 8 for additional information related to the licensed software.

Fair Value of Debt

At March 31, 2010, the carrying value of our debt was approximately $8.8 billion compared with $8.9 billion at December 31, 2009. The carrying value of our debt includes adjustments for both the unamortized fair value adjustments related to terminated hedge arrangements and fair value adjustments of debt instruments that are currently hedged.

The estimated fair value of our debt was approximately $9.1 billion at March 31, 2010 and approximately $9.3 billion at December 31, 2009. The estimated fair value of our senior notes is based on quoted market prices. The carrying value of remarketable debt approximates fair value due to the short-term nature of the attached interest rates. The fair value of our other debt is estimated using discounted cash flow analysis, based on rates we would currently pay for similar types of instruments.

Although we have determined the estimated fair value amounts using available market information and commonly accepted valuation methodologies, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, our estimates are not necessarily indicative of the amounts that we, or holders of the instruments, could realize in a current market exchange. The use of different assumptions and/or estimation methodologies could have a material effect on the estimated fair values. The fair value estimates are based on information available as of March 31, 2010 and December 31, 2009. These amounts have not been revalued since those dates, and current estimates of fair value could differ significantly from the amounts presented.

Text block that encapsulates the detailed table comprising the condensed financial statements (balance sheet, income statement and statement of cash flows), normally using the registrant (parent) as the sole domain member. If condensed consolidating financial statements are being presented, other domain members (in addition to parent) such as guarantor subsidiaries, non-guarantor subsidiaries, and the consolidation eliminations, will be included in order that the respective monetary amounts for each of the domains will aggregate to the respective amounts on the consolidated financial statements. The line items are the various captions used to compile the condensed financial statements. Using extensions, most, if not all, of the elements representing condensed financial statement captions will be the same as those used for the consolidated financial statements captions.

New Accounting Standards Pending Adoption [Abstract]

New Accounting Standards Pending Adoption


14.	New Accounting Standards Pending Adoption

Multiple-Deliverable Revenue Arrangements — In September 2009, the FASB amended authoritative guidance associated with multiple-deliverable revenue arrangements. This amended guidance addresses the determination of when individual deliverables within an arrangement may be treated as separate units of accounting and modifies the manner in which consideration is allocated across the separately identifiable deliverables. The amendments to authoritative guidance associated with multiple-deliverable revenue arrangements are effective for the Company on January 1, 2011, although the FASB does permit early adoption of the guidance provided that it is retroactively applied to the beginning of the year of adoption. The new accounting standard may be applied either retrospectively for all periods presented or prospectively to arrangements entered into or materially modified after the date of adoption. We are in the process of assessing the provisions of this new guidance and currently do not expect that the adoption will have a material impact on our consolidated financial statements. However, our adoption of this guidance may significantly impact our accounting and reporting for future revenue arrangements to the extent they are material.
