WASTE MANAGEMENT, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

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 as described in Note 13. 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 “WM,” we are referring only to Waste Management, Inc., the parent holding company.

Through the third quarter of 2012, we managed and evaluated our operations primarily through our Eastern, Midwest, Southern, Western and Wheelabrator operating Groups. Our four geographic operating Groups provide collection, transfer, disposal (in both solid waste and hazardous waste landfills) and recycling services for residential, commercial, industrial and municipal customers throughout North America. Our Wheelabrator Group provides waste-to-energy services and manages waste-to-energy facilities and independent power production plants. We also provide additional services that are not managed through our five Groups, including the operations of Oakleaf Global Holdings acquired on July 28, 2011 (“Oakleaf”), which are presented in this report as “Other.” Additional information related to our segments and to our acquisition of Oakleaf can be found in Note 8 and in Note 9, respectively.

In July 2012, we announced a reorganization of our operations, designed to streamline management and staff support and reduce our cost structure, while not disrupting our front-line operations. We are in the process of implementing the reorganization and we expect it to be completed by the end of 2012. Once the reorganization has been completed, our reportable segments will be realigned to conform with our new management structure. See Note 10 for additional information related to this reorganization.

The Condensed Consolidated Financial Statements as of September 30, 2012 and for the three and nine months ended September 30, 2012 and 2011 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, 2011.

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. 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 present the greatest amount of uncertainty relate to our accounting for landfills, environmental remediation liabilities, asset impairments, deferred income taxes and reserves associated with our insured and self-insured claims. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements.

In the second quarter of 2012, we believed that the fair value of our Wheelabrator Group could potentially be less than its carrying amount because of the negative effect on our revenues of the continued deterioration of electricity commodity prices, coupled with our continued increased exposure to market prices as a result of the expiration of several long-term, fixed-rate electricity commodity contracts at our waste-to-energy and independent power facilities, and the expiration of several long-term disposal contracts at above-market rates. As a result, we performed an interim impairment analysis of our Wheelabrator Group’s goodwill balance, which was $788 million as of June 30, 2012.

6

WASTE MANAGEMENT, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

We performed an interim quantitative assessment using both an income and a market approach, which indicated that the estimated fair value of our Wheelabrator Group exceeded its carrying value; however, the amount by which the fair value exceeded the carrying value declined significantly from the most recent annual impairment test performed at October 1, 2011. At that time, our Wheelabrator Group’s estimated fair value exceeded its carrying value by approximately 30%, as compared with slightly greater than 10% as of the interim impairment test performed in the second quarter of 2012. If market prices for electricity worsen or do not recover as we have projected, if our disposal rates continue to decline, or if our costs and capital expenditures exceed our forecasts, the estimated fair value of our Wheelabrator Group could decrease further and potentially result in an impairment charge in a future period. We continue to monitor our Wheelabrator Group for possible impairment of their goodwill balance.

Adoption of New Accounting Pronouncements

Fair Value Measurement — In May 2011, the Financial Accounting Standards Board (“FASB”) amended authoritative guidance associated with fair value measurements. This amended guidance defines certain requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. generally accepted accounting principles. The amendments to authoritative guidance associated with fair value measurements were effective for the Company on January 1, 2012 and have been applied prospectively. The adoption of this guidance did not have a material impact on our consolidated financial statements.

Comprehensive Income — In June 2011, the FASB issued amended authoritative guidance associated with comprehensive income, which requires companies to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This update eliminates the option to present the components of other comprehensive income as part of the statement of changes in equity. In December 2011, the FASB deferred the effective date of the specific requirement to present items that are reclassified out of accumulated other comprehensive income to net income alongside their respective components of net income and other comprehensive income. The amendments to authoritative guidance associated with comprehensive income were effective for the Company on January 1, 2012 and have been applied retrospectively. The adoption of this guidance did not have a material impact on our consolidated financial statements.

Debt Classification

As of September 30, 2012, we had $708 million of debt maturing within the next twelve months, including U.S. $117 million of advances outstanding under our Canadian credit facility, $400 million of 6.375% senior notes that mature in November 2012 and $141 million of tax-exempt bonds. We also had $663 million of tax-exempt borrowings subject to repricing within the next twelve months. We have classified $545 million of these tax-exempt borrowings as long-term based on our intent and ability to fund any failed remarketings with available capacity under our revolving credit facility.

Revolving Credit and Letter of Credit Facilities

As of September 30, 2012, we had an aggregate committed capacity of $2.5 billion for letters of credit under various credit facilities. Our $2.0 billion revolving credit facility expires in May 2016 and is our primary source of letter of credit capacity. Our remaining letter of credit capacity is provided under facilities with terms that extend from June 2013 to June 2015. As of September 30, 2012, we had an aggregate of $1.5 billion of letters of credit outstanding under various credit facilities. Approximately $1.0 billion of these letters of credit have been issued under our revolving credit facility.

Debt Borrowings and Repayments

Revolving credit facility —During the nine months ended September 30, 2012, we have had net repayments under our revolving credit facility of $150 million.

Canadian credit facility —We repaid $27 million of net advances under our Canadian credit facility during the nine months ended September 30, 2012.

Senior notes —In September 2012, we issued $500 million of 2.9% senior notes due September 15, 2022. The net proceeds from the debt issuance were $495 million. We intend to use a portion of these proceeds to repay $400 million of 6.375% senior notes that mature in November 2012. All remaining proceeds will be used for general corporate purposes. Pending repayment of the senior notes due November 2012, we used a portion of the proceeds to repay borrowings outstanding under our revolving credit facility.

Tax-exempt bonds —During the nine months ended September 30, 2012, we repaid $91 million of our tax-exempt bonds with available cash at their scheduled maturities. In addition, we issued $43 million of tax-exempt bonds, the proceeds of which were used to repay tax-exempt bonds at their scheduled maturities.

4.    Derivative Instruments and Hedging Activities

We have not offset fair value amounts recognized for our derivative instruments. For information related to the inputs used to measure our derivative assets and liabilities at fair value, refer to Note 12.

Interest Rate Derivatives

Interest Rate Swaps

We have used interest rate swaps to maintain a portion of our debt obligations at variable market interest rates. As of September 30, 2012 and December 31, 2011, we had approximately $6.6 billion and $6.1 billion in fixed-rate senior notes outstanding, respectively. As of December 31, 2011, the interest payments on $1 billion, or 16%, of these senior notes were swapped to variable interest rates to protect the debt against changes in fair value due to changes in benchmark interest rates. In April 2012, we elected to terminate our interest rate swaps and, upon termination, we received $76 million in cash for their fair value plus accrued interest receivable. The terminated interest rate swaps were associated with senior notes that are scheduled to mature from November 2012 to March 2018. The associated fair value adjustments to long-term debt are being amortized as a reduction to interest expense over the remaining terms of the underlying debt using the effective interest method. The cash proceeds received from our termination of the swaps have been classified as a change in “Other assets” within “Net cash provided by operating activities” in the Condensed Consolidated Statement of Cash Flows.

We 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 our debt instruments by $85 million as of September 30, 2012 and $102 million as of December 31, 2011. 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 fair value adjustments from active interest rate swaps and the underlying hedged items on our results of operations (in millions):

(b) Due to our election to terminate our interest rate swap portfolio with a notional amount of $1 billion in April 2012, periodic settlements of active swap agreements have decreased and amortization to interest expense of terminated swap agreements has increased.

Forward-Starting Interest Rate Swaps

In 2009, we entered into forward-starting interest rate swaps with a total notional value of $525 million to hedge the risk of changes in semi-annual interest payments due to fluctuations in the forward ten-year LIBOR swap rate for anticipated fixed-rate debt issuances in 2011, 2012 and 2014. We designated these forward-starting interest rate swaps as cash flow hedges.

During the first quarter of 2011 and the third quarter of 2012, $150 million and $200 million, respectively, of these forward-starting interest rate swaps were terminated contemporaneously with the actual issuance of senior notes in February 2011 and September 2012, respectively, and we paid cash of $9 million and $59 million, respectively, to settle the liabilities related to these swap agreements. The ineffectiveness recognized upon termination of these hedges was immaterial and the related deferred losses continue to be recognized as a component of “Accumulated other comprehensive income.” The deferred losses are being amortized as an increase to interest expense over the ten-year life of the related senior note issuances using the effective interest method.

The active forward-starting interest rate swaps outstanding as of September 30, 2012 relate to an anticipated debt issuance in March 2014. As of September 30, 2012, the fair value of these active interest rate derivatives was comprised of $42 million of long-term liabilities compared with $32 million of long-term liabilities as of December 31, 2011.

We recognized pre-tax and after-tax losses of $3 million and $2 million, respectively, to other comprehensive income for changes in the fair value of our forward-starting interest rate swaps during the three months ended September 30, 2012 and pre-tax and after-tax losses of $28 million and $17 million, respectively, during the nine months ended September 30, 2012. We recognized pre-tax and after-tax losses of $46 million and $28 million, respectively, to other comprehensive income for changes in the fair value of our forward-starting interest rate swaps during the three months ended September 30, 2011 and $53 million and $33 million, respectively, during the nine months ended September 30, 2011. Pre-tax and after-tax losses of $2 million and $1 million, respectively, for the three and nine months ended September 30, 2012 were reclassified out of accumulated other comprehensive income and into interest expense. The losses reclassified to interest expense were immaterial for the three and nine months ended September 30, 2011. As of September 30, 2012, $7 million (on a pre-tax basis) is scheduled to be reclassified as an increase to interest expense over the next twelve months. There was no significant ineffectiveness associated with these hedges during the three and nine months ended September 30, 2012 or 2011.

Treasury Rate Locks

In prior years, we used Treasury rate locks to secure underlying interest rates in anticipation of senior note issuances. The deferred losses, net of taxes, associated with these cash flow hedges were $8 million at September 30, 2012 and $12 million at December 31, 2011, which are included in “Accumulated other comprehensive income.” These deferred losses are reclassified as an increase to interest expense over the life of the related senior note issuances, which extend through 2032. Pre-tax and after-tax losses of $2 million for the three-month period ended September 30, 2012 and pre-tax and after-tax losses of $6 million and $4 million, respectively, for the nine-month period ended September 30, 2012, were reclassified out of accumulated other comprehensive income and into interest expense. Pre-tax and after-tax losses of $2 million and $1 million, respectively, for the three-month period ended September 30, 2011, and pre-tax and after-tax losses of $6 million and $3 million, respectively, for the nine-month period ended September 30, 2011, were reclassified out of accumulated other comprehensive income and into interest expense. As of September 30, 2012, $2 million (on a pre-tax basis) is scheduled to be reclassified as an increase to interest expense over the next twelve months.

Credit-Risk-Related Contingent Features

Our interest rate derivative instruments have in the past and may in the future contain provisions related to the Company’s credit rating. These provisions generally provide that if the Company’s credit rating were to fall to specified levels below investment grade, the counterparties have the ability to terminate the derivative agreements, resulting in settlement of all affected transactions. As of September 30, 2012, we did not have any interest rate derivatives outstanding that contained these credit-risk related provisions.

Foreign Currency Derivatives

We use foreign currency exchange rate derivatives to hedge our exposure to fluctuations in exchange rates for anticipated intercompany cash transactions between Waste Management Holdings, Inc., a wholly-owned subsidiary (“WM Holdings”), and its Canadian subsidiaries. As of September 30, 2012, we had 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 as of September 30, 2012 include C$370 million of principal, which is scheduled for payment on October 31, 2013, and scheduled interest payments of C$11 million on November 30, 2012 and C$10 million on October 31, 2013. We designated the forward contracts as cash flow hedges.

Gains or losses on the underlying hedged items attributable to foreign currency exchange risk are recognized in current earnings. The gains or losses on our foreign currency forward contracts that are reclassified out of accumulated other comprehensive income are recognized as adjustments to other income and expense, which is the same financial statement line item where offsetting gains or 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 comprehensive income and results of operations (in millions):

Three Months Ended September 30,	Derivative Gain  or (Loss) Recognized in OCI (Effective Portion)			Statement of     Operations Classification	Derivative Gain  or (Loss) Reclassified from AOCI into Income (Effective Portion)
2012	$	(15	)	Other income (expense)	$	(14	)
2011	$	25		Other income (expense)	$	33

Nine Months Ended September 30,	Derivative Gain  or (Loss) Recognized in OCI (Effective Portion)			Statement of     Operations Classification	Derivative Gain  or (Loss) Reclassified from AOCI into Income (Effective Portion)
2012	$	(14	)	Other income (expense)	$	(17	)
2011	$	11		Other income (expense)	$	21

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 after-tax losses of $9 million and $8 million during the three and nine months ended September 30, 2012, respectively, and after-tax gains of $15 million and $7 million during the three and nine months ended September 30, 2011, respectively. After-tax adjustments for the reclassification of losses from accumulated other comprehensive income into income were $8 million and $10 million during the three and nine months ended September 30, 2012, respectively. After-tax adjustments for the reclassification of gains from accumulated other comprehensive income into income were $20 million and $13 million during the three and nine months ended September 30, 2011, respectively. Ineffectiveness has been included in other income and expense during each of the reported periods. There was no significant ineffectiveness associated with these hedges during the three and nine months ended September 30, 2012 or 2011.

Electricity Commodity Derivatives

We use short-term “receive fixed, pay variable” electricity commodity swaps to reduce the variability in our revenues and cash flows caused by fluctuations in the market prices for electricity. We hedged 1.55 million megawatt hours, or approximately 50%, of our Wheelabrator Group’s full year 2011 merchant electricity sales, and the swaps executed through September 30, 2012 are expected to hedge about 628,800 megawatt hours, or 20%, of the Wheelabrator Group’s full year 2012 merchant electricity sales. For the three-month periods ended September 30, 2012 and 2011, we hedged 16% and 46%, respectively, of our merchant electricity sales. For the nine-month periods ended September 30, 2012 and 2011, we hedged 21% and 49%, respectively, of our merchant electricity sales.

We recognized pre-tax and after-tax losses of $3 million and $2 million, respectively, in other comprehensive income for changes in the fair value of our electricity commodity derivatives during the three months ended September 30, 2012 and pre-tax and after-tax gains of $1 million and less than $1 million, respectively, for the nine months ended September 30, 2012. We recognized pre-tax and after-tax adjustments of $2 million and $1 million, respectively, for the reclassification of gains from accumulated other comprehensive income into income as a component of “Operating revenues” during the three months ended September 30, 2012 and $9 million and $5 million, respectively, for the nine months ended September 30, 2012. All financial statement impacts associated with these derivatives were immaterial for the three and nine months ended September 30, 2011. There was no significant ineffectiveness associated with these cash flow hedges during the three and nine months periods ended September 30, 2012 or 2011.

5.    Income Taxes

Our effective income tax rate for the three and nine months ended September 30, 2012 was 36.1% and 34.5%, respectively, compared with 32.3% and 34.0% for the comparable prior year periods. We evaluate our effective income tax rate at each interim period and adjust it accordingly as facts and circumstances warrant. The differences between federal income taxes computed at the federal statutory rate and reported income taxes for the three and nine months ended September 30, 2012 were primarily due to the favorable impact of federal tax credits, audit settlements and the realization of additional acquired federal net operating losses. These favorable items were more than offset during the third quarter and almost entirely offset during the nine months by the unfavorable impacts of adjustments to our accruals and related deferred taxes due to the filing of our 2011 income tax returns, state and local income taxes, a Canadian provincial tax rate increase and the tax implications of impairments of unconsolidated investments. The differences between federal income taxes computed at the federal statutory rate and reported income taxes for the three and nine months ended September 30, 2011 were primarily due to the favorable impact of federal tax credits, audit settlements and adjustments to our accruals due to the filing of our 2010 income tax returns, offset in part by the unfavorable impact of state and local income taxes.

Investment in Refined Coal Facility — In January 2011, we acquired a noncontrolling interest in a limited liability company, which was established to invest in and manage a refined coal facility in North Dakota. The facility’s refinement processes qualify for federal tax credits that are expected to be realized through 2019 in accordance with Section 45 of the Internal Revenue Code. Our initial consideration for this investment consisted of a cash payment of $48 million.

We account for our investment in this entity using the equity method of accounting, recognizing our share of the entity’s results and other reductions in “Equity in net losses of unconsolidated entities,” within our Condensed Consolidated Statement of Operations. During the three and nine months ended September 30, 2012 and 2011, we recognized less than $1 million and $2 million, respectively, of net losses resulting from our share of the entity’s operating losses. Our tax provision for the three and nine months ended September 30, 2012 and 2011 was reduced, primarily as a result of tax credits realized from this investment, by $6 million and $14 million and by $4 million and $11 million, respectively. See Note 13 for additional information related to this investment.

Investment in Federal Low-income Housing Tax Credits — In April 2010, we acquired a noncontrolling interest in a limited liability company established to invest in and manage low-income housing properties. The entity’s low-income housing investments qualify for federal tax credits that are expected to be realized through 2020 in accordance with Section 42 of the Internal Revenue Code.

We account for our investment in this entity using the equity method of accounting. We recognize our share of the entity’s results and reductions in the value of our investment in “Equity in net losses of unconsolidated entities,” within our Condensed Consolidated Statement of Operations. The value of our investment decreases as the tax credits are generated and utilized. During the three and nine months ended September 30, 2012, we recognized $6 million and $18 million of losses relating to our equity investment in this entity, $2 million and $5 million of interest expense, and a reduction in our tax provision of $11 million (including $8 million of tax credits) and $27 million (including $18 million of tax credits), respectively. During the three and nine months ended September 30, 2011, we recognized $5 million and $17 million of losses associated with our equity investment, $2 million and $6 million of interest expense, and a reduction in our tax provision of $9 million (including $7 million of tax credits) and $27 million (including $18 million of tax credits), respectively.

Recent Legislation — The Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act, signed into law on December 17, 2010, included an extension of the bonus depreciation allowance through the end of 2012 and increased the amount of qualifying capital expenditures that can be depreciated immediately from 50% to 100%. The 100% depreciation deduction applied to qualifying property placed in service from September 8, 2010 through December 31, 2011. The depreciation deduction for qualifying property placed in service in 2012 has been reduced to 50%. The acceleration of deductions on capital expenditures resulting from the bonus depreciation provisions has no impact on our effective tax rate, but reduces our cash taxes in the periods in which the deductions are taken.

The acceleration of depreciation deductions related to qualifying property additions in 2011 decreased our full year 2011 cash taxes by approximately $190 million and, based on our current forecast of 2012 capital expenditures, we estimate a reduction in our full year 2012 cash taxes of approximately $90 million related to qualifying property additions in 2012. However, taking accelerated deductions results in increased cash taxes in subsequent periods when the deductions for these capital expenditures would have otherwise been taken.

7.    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 final capping, 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 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 are 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 claims programs. “General liability” refers to the self-insured portion of specific third party claims made against us that may be covered under our commercial General Liability Insurance Policy. 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 accruals for these liabilities could be revised if future occurrences or loss development significantly differ from our 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.

Guarantees — In the ordinary course of our business, WM and WM Holdings enter into guarantee agreements associated with their subsidiaries’ operations. Additionally, WM 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 and certain performance requirements of, and provided indemnification to, third parties in the ordinary course of business for both consolidated and unconsolidated entities. Guarantee agreements outstanding as of September 30, 2012 include (i) guarantees of unconsolidated entities’ financial obligations maturing through 2020 for maximum future payments of $10 million; and (ii) agreements guaranteeing certain market value losses for approximately 850 homeowners’ properties adjacent to or near 20 of our landfills. Our indemnification obligations generally arise from 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, and 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 and 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. We recognize and accrue for an estimated remediation liability when we determine that such liability is both probable and reasonably estimable. 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 site remediation alternatives identified in the investigation of the extent of environmental impact. 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 $264 million recorded in the Condensed Consolidated Financial Statements as of September 30, 2012. Our ultimate responsibility may differ materially from current estimates. It is possible that technological, regulatory or enforcement developments, the results of environmental studies, the inability to identify other PRPs, the inability of other PRPs to contribute to the settlements of such liabilities, or other factors could require us to record additional liabilities. Our ongoing review of our remediation liabilities, in light of relevant internal and external facts and circumstances, 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 September 30, 2012, we had been notified that we are a PRP in connection with 80 locations listed on the EPA’s Superfund National Priorities List, or NPL. Of the 80 sites at which claims have been made against us, 16 are sites we own. Each of the NPL sites we own was initially developed as a landfill disposal facility by one or more other parties. 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 64 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 involving NPL sites that we do not own are based on 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.

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, or such proceedings are known to be contemplated, unless we reasonably believe that the matter will result in no monetary sanctions, or in monetary sanctions, exclusive of interest and costs, of less than $100,000. The following matters are disclosed in accordance with that requirement. We do not currently believe that the eventual outcome of any such matters, individually or in the aggregate, could have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

On April 4, 2006, the EPA issued a Notice of Violation (“NOV”) to Waste Management of Hawaii, Inc., an indirect wholly-owned subsidiary of WM, 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 (“GCCS”) for the Waimanalo Gulch Sanitary Landfill on Oahu. The EPA has also indicated that it will seek penalties and injunctive relief as part of the NOV enforcement for elevated landfill temperatures that were recorded after installation of the GCCS. 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.

On December 22, 2011, the Harris County Attorney in Houston, Texas filed suit against McGinnes Industrial Maintenance Corporation (“MIMC”), WM and Waste Management of Texas, Inc., et al, seeking civil penalties and attorneys’ fees for alleged violations of the Texas Water Code and the Texas Health and Safety Code. The County’s Original Petition pending in the District Court of Harris County, Texas alleges the mismanagement of certain waste pits that were operated from 1965 to 1966 by MIMC. In 1998, a predecessor of WM acquired the stock of the parent entity of MIMC.

On April 20, 2012, the Pennsylvania Department of Environmental Protection (“PADEP”) transmitted a proposed Consent Order and Agreement to Waste Management of Pennsylvania, Inc., an indirect wholly-owned subsidiary of WM, for alleged violations of Pennsylvania solid waste regulations, including certain operations failures, at the Northwest Sanitary Landfill. PADEP has indicated that it is seeking penalties and corrective action.

Additionally, the United States Attorney’s Office for the District of Hawaii has commenced an investigation prompted by allegations of violations of the federal Clean Water Act involving discharge of stormwater at the Waimanalo Gulch Sanitary Landfill, located on Oahu, in connection with three major storm events in December 2010 and January 2011. No formal enforcement action has been brought against the Company. While we could potentially be subject to sanctions, including requirements to pay monetary penalties, in connection with a future proceeding that may arise from the investigation, a range of loss cannot currently be estimated because no proceeding has yet commenced and significant factual and legal issues remain. We are cooperating with the U.S. Attorney’s Office.

Litigation — In April 2002, certain former participants in the ERISA plans of WM Holdings filed a lawsuit in the U.S. District Court for the District of Columbia in a case entitledWilliam S. Harris, et al. v. James E. Koenig, et al. The lawsuit attempts to increase the recovery of a class of ERISA plan participants on behalf of the plan 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, the litigation against WM in Texas that was settled in 2002, as well as the decision to offer WM common stock as an investment option within the plan beginning in 1990, despite alleged knowledge by at least two members of the investment committee of financial misstatement by WM during the relevant time period.

During the second quarter of 2010, the Court dismissed certain claims against individual defendants, including all claims against each of the current members of our Board of Directors. Previously, plaintiffs dismissed all claims related to the settlement of the securities class action against WM that was settled in 2002,

17

WASTE MANAGEMENT, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

and the court certified a limited class of participants who may bring claims on behalf of the plan, but not individually. During the third quarter of 2011, the Court ruled in favor of WM and two former employees dismissing all claims brought by the plaintiffs related to the decision to offer WM stock as an investment option within the plan. We have reached a settlement with the plaintiffs on this matter, with a proposed class settlement agreement submitted to the Court on October 17, 2012. We anticipate all the details with respect to the settlement will be resolved and finally approved by the Court within the next few months. We do not believe the settlement could have a material adverse effect on the Company’s business, financial condition, results of operations, or cash flows.

In October 2011 and January 2012, we were named as a defendant in a purported class action in the Circuit Court of Sarasota County, Florida and the Circuit Court of Lawrence County Alabama, respectively. These cases primarily pertain to our fuel and environmental charges included on our invoices, generally alleging that such charges were not properly disclosed, were unfair and were contrary to the customer service contracts. The law firm that filed these lawsuits had filed, in 2008, a purported class action against subsidiaries of WM in Bullock County, Alabama, making similar allegations. The prior Alabama suit was removed to federal court, where the federal court ultimately dismissed the plaintiffs’ national class action claims. The plaintiffs then elected to dismiss the case without prejudice. We will vigorously defend against these pending lawsuits. Given the inherent uncertainties of litigation, including the early stage of these cases, the unknown size of any potential class, and legal and factual issues in dispute, the outcome of these cases cannot be predicted and a range of loss cannot currently be estimated.

From time to time, we are also 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. Additionally, we often enter into contractual arrangements with landowners imposing obligations on us to meet certain regulatory or contractual conditions upon site closure or upon termination of the agreements. Compliance with these arrangements is inherently subject to subjective determinations and may result in disputes, including litigation.

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 sales and marketing practices and 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 the eventual outcome of any such actions could have a material adverse effect on the Company’s business, financial condition, results of operations, or cash flows.

WM’s charter and bylaws provide that WM shall indemnify against all liabilities and expenses, and upon request shall advance expenses to, any person who is subject to a pending or threatened proceeding because such person is a director or officer of the Company. Such indemnification is required to the maximum extent permitted under Delaware law. Accordingly, the director or officer must reimburse the Company for any fees advanced if it is later determined that the director or officer was not entitled to have such fees advanced under Delaware law. Additionally, WM has entered into separate indemnification agreements with each of the members of its Board

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

of Directors, and the employment agreements between WM and its Chief Executive Officer, Chief Financial Officer and other executive and senior vice presidents contain a direct contractual obligation of the Company to provide indemnification to the executive. 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 or other actions or proceedings that may be brought against its former or current officers, directors and employees.

Multiemployer Defined Benefit Pension Plans — About 20% of our workforce is covered by collective bargaining agreements with various union locals across the United States and Canada. As a result of some of these agreements, certain of our subsidiaries are participating employers in a number of trustee-managed multiemployer, defined benefit pension plans for the affected employees. In connection with our ongoing renegotiation of various collective bargaining agreements, we may discuss and negotiate for the complete or partial withdrawal from one or more of these pension plans. A complete or partial withdrawal from a multiemployer pension plan may also occur if employees covered by a collective bargaining agreement vote to decertify a union from continuing to represent them.

One of the most significant multiemployer pension plans in which we have participated is the Central States Southeast and Southwest Areas Pension Plan (“Central States Pension Plan”). The Central States Pension Plan is in “critical status” as defined by the Pension Protection Act of 2006. Since 2008, certain of our affiliates have bargained to remove covered employees from the Central States Pension Plan, resulting in a series of withdrawals. In October 2011, employees at the last of our affiliates with active participants in the Central States Pension Plan voted to decertify the union that represented them, withdrawing themselves from the Central States Pension Plan.

We are still negotiating and litigating final resolutions of our withdrawal liability for previous withdrawals, including our recent final withdrawal mentioned above, but we do not believe any additional liability above the charges we have already recognized for such previous withdrawals could be material to the Company’s business, financial condition, results of operations or cash flows. We also do not believe that any future withdrawals, individually or in the aggregate, from the multiemployer plans to which we contribute, could have a material adverse effect on our business, financial condition or liquidity. However, such withdrawals could have a material adverse effect on our results of operations for a particular reporting period, depending on the number of employees withdrawn in any future period and the financial condition of the multiemployer plan(s) at the time of such withdrawal(s).

Tax Matters — We are currently in the examination phase of IRS audits for the tax years 2011 and 2012 and expect these audits to be completed within the next three and 15 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 2000. We have finalized audits in Canada through the 2005 tax year and are not currently under audit for any subsequent tax years in Canada. On July 28, 2011, we acquired Oakleaf, which is subject to IRS examinations for years dating back to 2009 and state income tax examinations for years dating back to 2002. Pursuant to the terms of our acquisition of Oakleaf, we are entitled to indemnification for Oakleaf’s pre-acquisition tax liabilities. We maintain a liability for uncertain tax positions, 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.

8.    Segment and Related Information

Through the third quarter of 2012, we managed and evaluated our operations primarily through our Eastern, Midwest, Southern, Western and Wheelabrator operating Groups. These five Groups are presented below as our reportable segments. Our four geographic operating Groups provide collection, transfer, disposal (in both solid waste and hazardous waste landfills) and recycling services for residential, commercial, industrial and municipal

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

customers throughout North America. Our fifth Group is the Wheelabrator Group, which provides waste-to-energy services and manages waste-to-energy facilities and independent power production plants in the United States and participates in the design, construction, operation and management of waste-to-energy facilities through investments and consolidated entities in China and Europe. In addition, the Oakleaf operations we acquired on July 28, 2011 represent a separate operating segment; however, they do not meet the criteria to be presented as a separate reportable segment. The operations not managed through our five operating Groups, including the Oakleaf operations, are presented herein as “Other.” See Note 9 for additional information related to our acquisition of Oakleaf.

In July 2012, we announced a reorganization of our operations, designed to streamline management and staff support and reduce our cost structure, while not disrupting our front-line operations. We are in the process of implementing the reorganization, which includes the elimination of our four existing geographic Groups, and we expect it to be completed by the end of 2012. Once the reorganization has been completed, our reportable segments will be realigned to conform with our new management structure. See Note 10 for additional information related to this reorganization.

WASTE MANAGEMENT, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

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, changes in commodity prices and by general economic conditions. In addition, our revenues and income from operations typically reflect seasonal patterns. Our operating revenues normally tend to be somewhat higher in the summer months, primarily due to the traditional seasonal increase in the volume of construction and demolition waste. Historically, the volumes of industrial and residential waste in certain regions in which we operate have tended 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 that most often impact our Southern Group, can actually increase our revenues in the areas affected. While weather-related and other “one-time” occurrences can boost revenues through additional work, as a result of significant start-up costs and other factors, such revenue sometimes 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.

9.    Acquisitions

Oakleaf— On July 28, 2011, we paid $432 million, net of cash received of $4 million and inclusive of certain adjustments, to acquire Oakleaf. Oakleaf provides outsourced waste and recycling services principally through a nationwide network of third-party haulers. The operations we acquired generated approximately $580 million in revenues in 2010. We acquired Oakleaf to advance our growth and transformation strategies and increase our national accounts customer base while enhancing our ability to provide comprehensive environmental solutions. For the year ended December 31, 2011, we incurred $1 million of acquisition-related costs, which were classified as “Selling, general and administrative” expenses. For the three- and nine-month periods ended September 30, 2012, Oakleaf recognized revenues of $143 million and $438 million, respectively, and net losses of $4 million and $8 million, respectively. These amounts are included in our Condensed Consolidated Statement of Operations.

The following table shows adjustments since December 31, 2011 to the allocation of the purchase price of Oakleaf to the assets acquired and liabilities assumed based on their estimated fair value and is final as of September 30, 2012 (in millions):

	December  31, 2011			Adjustments			September  30, 2012
Accounts and other receivables	$	70		$	1		$	71

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The following table presents the final allocation of the purchase price to other intangible assets (amounts in millions, except for amortization periods):

	Amount		Weighted Average Amortization Periods (In Years)
Customer relationships	$	74	10.0
Vendor relationships		4	10.0
Trademarks		9	15.0
	$	87	10.5

Goodwill of $328 million was calculated as the excess of the consideration paid over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Goodwill is a result of expected synergies from combining the Company’s operations with Oakleaf’s national accounts customer base and vendor network. The vendor-hauler network expands our partnership with third-party service providers. In many cases we can provide vendor-haulers with opportunities to maintain and increase their business by utilizing our extensive post-collection network. We believe this will generate significant benefits for the Company and for the vendor-haulers. Goodwill has been assigned to our four geographic Groups as they are expected to benefit from the synergies of the combination. Goodwill related to this acquisition is not deductible for income tax purposes.

The following pro forma consolidated results of operations for the three and nine months ended September 30, 2011 have been prepared as if the acquisition of Oakleaf occurred at January 1, 2011 (in millions, except per share amounts):

	Three Months  Ended September 30, 2011		Nine Months  Ended September 30, 2011
Operating revenues	$	3,566	$	10,287
Net income attributable to Waste Management, Inc.		272		689
Basic earnings per common share		0.58		1.46
Diluted earnings per common share		0.58		1.45

Other — During the nine months ended September 30, 2012, we paid $94 million for interests in oil and gas producing properties through two transactions. The purchase price was allocated primarily to “Property and equipment.” Additionally, during the nine months ended September 30, 2012 we acquired 21 other businesses related to our collection and recycling operations.

10.    Restructuring

2012 Restructurings —In July 2012, we announced a reorganization of operations, designed to streamline management and staff support and reduce our cost structure, while not disrupting our front-line operations. Principal organizational changes being implemented include removal of the management layer consisting of our four existing geographic Groups; consolidation and reduction of the number of Areas managing the core collection, disposal and recycling businesses from 22 to 17; and reduction of corporate support staff in an effort to better align support with the needs of the operating units.

We are in the process of implementing this restructuring plan and we expect it to be completed by the end of 2012. We currently estimate that approximately 700 employee positions throughout the Company, including positions at both the management and support levels, will be eliminated. Voluntary separation arrangements were offered to many in certain levels of management.

23

WASTE MANAGEMENT, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Additionally, during the first nine months of 2012, we recognized employee severance and benefits restructuring charges associated with the reorganization of Oakleaf that began in 2011 and certain other actions taken by the Company in early 2012.

During the third quarter of 2012, we recognized pre-tax charges of $44 million associated with these restructuring activities, $39 million of which related to employee severance and benefit costs. The remainder of the charge was primarily related to abandoned operating leases. We currently expect to incur additional restructuring charges in the fourth quarter of 2012, consisting of employee severance and benefits expenses and facility, lease and other related expenses, in the range of $20 million to $30 million. The additional restructuring charges are an estimate, and actual charges may vary materially based on various factors, including the number of employee terminations; facility, lease or other restructuring charges that are not yet estimable; and changes in management’s objectives.

The following table summarizes the employee severance and benefit costs and other charges recognized for these restructuring activities by each of our current reportable segments and our Corporate and Other organizations for the three and nine months ended September 30, 2012 (in millions):

	Three Months  Ended September 30, 2012		Nine Months  Ended September 30, 2012
Eastern	$	3	$	4
Midwest		5		5
Southern		5		7
Western		9		9
Wheelabrator		1		1
Corporate and Other		21		25
Total	$	44	$	51

2011 Restructurings — Beginning in July 2011, we took steps to streamline our organization as part of our cost savings programs. This reorganization eliminated over 700 employee positions throughout the Company, including approximately 300 open positions. Additionally, subsequent to our acquisition of Oakleaf, we incurred charges in connection with restructuring that organization. During the year ended December 31, 2011, we recognized a total of $19 million of pre-tax restructuring charges, of which $18 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.

Through September 30, 2012, we have paid a total of approximately $29 million of the employee severance and benefit costs incurred as a result of these combined 2012 and 2011 restructuring efforts.

11.    Asset Impairments and Unusual Items

(Income) expense from divestitures, asset impairments and unusual items — During the third quarter of 2012, we recognized impairment charges aggregating $21 million, relating in large part to (i) the impairment of a note receivable from an entity that we invested in that is now being liquidated (see “Equity in net losses of unconsolidated entities”discussion below), (ii) the impairment of certain related assets due to our decision not to use or develop those assets and (iii) the impairment of an oil and gas well as a result of projected operating losses that caused us to write-down the carrying value of the oil and gas well to its estimated fair value. These charges are included in our “Other” operations in Note 8.

During the second quarter of 2012, we recognized impairment charges of $34 million, relating primarily to two facilities in our medical waste services business as a result of projected operating losses at each of these facilities. We wrote down the carrying values of the facilities’ operating permits and property, plant and equipment to their estimated fair values. Our medical waste services business is included in our “Other” operations in Note 8.

24

WASTE MANAGEMENT, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

During the third quarter of 2011, we recognized impairment charges relating to two facilities in our medical waste services business, in addition to the two facilities impaired in the second quarter and discussed above, as a result of the closure of one site and as a result of continuing operating losses at the other site. We wrote down the net book values of the sites to their estimated fair values.

Equity in net losses of unconsolidated entities — During the third quarter of 2012, we recognized a charge of $10 million related to a payment we made under a guarantee on behalf of an unconsolidated entity accounted for under the equity method.

Other income (expense) — During the third quarter of 2012, we recognized an impairment charge of $14 million relating to an other-than-temporary decline in the value of an investment accounted for under the cost method. We wrote down the carrying value of our investment to its fair value based on other third-party investors’ recent transactions in these securities, which are considered to be the best evidence of fair value currently available. This charge is recorded in “Other, net” in our Condensed Consolidated Statement of Operations.

Fair Value of Available-for-sale Securities — The available-for-sale securities measured using Level 1 inputs are primarily included in long-term “Other assets” in our Condensed Consolidated Balance Sheets. The fair value of available-for-sale securities measured using Level 3 inputs consists of redeemable preferred stock that was acquired in November 2011 and is included in “Investments in unconsolidated entities” in our Condensed Consolidated Balance Sheets. The redeemable preferred stock is recorded at fair value based on other third-party investors’ recent or pending transactions in these securities, which are considered to be the best evidence of fair value currently available. When this evidence is not available, we use other valuation techniques as appropriate and available. These valuation methodologies may include transactions in similar instruments, discounted cash flow techniques, third-party appraisals or industry multiples and public comparables.

Fair Value of Debt

At September 30, 2012, the carrying value of our debt was approximately $10.0 billion compared with $9.8 billion at December 31, 2011. The carrying value of our debt includes adjustments associated with fair value hedge accounting related to our interest rate swaps as discussed in Note 4.

The estimated fair value of our debt was approximately $11.5 billion at September 30, 2012 and approximately $10.8 billion at December 31, 2011. The estimated fair value of our senior notes is based on quoted market prices. The carrying value of remarketable debt and borrowings under our revolving credit facilities approximates fair value due to the short-term nature of the interest rates. The fair value of our other debt is estimated using discounted cash flow analysis, based on current market rates for similar types of instruments. The increase in the fair value of our debt when comparing September 30, 2012 with December 31, 2011 is attributable to net borrowings during 2012, increases in market prices for corporate debt securities and decreases in current market rates on fixed-rate tax-exempt bonds.

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 Level 2 inputs of the fair value hierarchy available as of September 30, 2012 and December 31, 2011. These amounts have not been revalued since those dates, and current estimates of fair value could differ significantly from the amounts presented.

13.    Variable Interest Entities

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 entity and, therefore, have consolidated 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 (“Hancock”) owns 99.5% of LLC I and 99.75% of LLC II is owned by LLC I and the CIT Group (“CIT”). 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. Under the LLC agreements, the LLCs shall be dissolved upon the occurrence of any of the following events: (i) a written decision of all members of the LLCs; (ii) December 31, 2063; (iii) a court’s dissolution of the LLCs; or (iv) the LLCs ceasing to own any interest in the waste-to-energy facilities.

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 September 30, 2012 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. These payments are subject to adjustment based on factors that include the fair market value of rents for the facilities and lease payments made through the re-measurement dates. In addition, 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 and consolidate these entities in our Consolidated Financial Statements 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 September 30, 2012 and December 31, 2011, our Condensed Consolidated Balance Sheets included $299 million and $308 million, respectively, of net property and equipment associated with the LLCs’ waste-to-energy facilities and $250 million and $246 million, respectively, in noncontrolling interests associated with Hancock’s and CIT’s interests in the LLCs. As of September 30, 2012 and December 31, 2011, all debt obligations of the LLCs had been paid in full and, therefore, the LLCs had no liabilities. We recognized reductions in earnings of $9 million and $34 million for the three and nine months ended September 30, 2012 respectively, and $13 million and $38 million for the three and nine months ended September 30, 2011, respectively, 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 WM’s consolidation.

Significant Unconsolidated Variable Interest Entities

Investment in U.K. Waste-to-Energy and RecyclingEntity — In the first quarter of 2012, we established a U.K. limited liability company (the “Ltd.”) along with our joint venture partner, a commercial entity in the waste management industry, to develop, construct, operate and maintain a waste-to-energy and recycling facility in England. We own a 50% interest in this joint venture. The total cost of constructing this facility is expected to be £200 million, or $323 million based on the exchange rate as of September 30, 2012. The Ltd. will be funded primarily through loans from the joint venture partners and loans under the Ltd.’s credit facility agreements with third-party financial institutions. The funds loaned under the credit facility agreements will be used for the development and construction of the facility. We are committed to provide up to £57 million, or $92 million based on the exchange rate as of September 30, 2012, of funding to the Ltd. Our actual commitment may be more or less depending on the actual cost of the facility. Through September 30, 2012, we had funded approximately £7 million, or $11 million, through loans and less than $1 million through equity contributions. These amounts are included in our Condensed Consolidated Balance Sheet as long-term “Other assets” and “Investments in unconsolidated entities,” respectively. In addition to the funding commitments described above, the Ltd. has entered into certain foreign currency and interest rate derivatives at the direction of the authority. The impacts of gains or losses incurred on these derivatives will ultimately be remitted to or recoverable from the authority under the terms of the project, and accordingly, are not reflected in our equity in net losses of unconsolidated entities. We also have guaranteed the performance of certain management services for the project for which our maximum exposure under the guarantee is not material.

In addition, a wholly-owned subsidiary of the Company will be responsible for constructing the waste-to-energy facility for the Ltd. under a fixed-price construction contract. Once the facility is constructed, a majority-owned subsidiary of the Company will be responsible for operating and maintaining the facility for the Ltd. under a substantially fixed-price operating and maintenance contract. Under the operating and maintenance contract, we have guaranteed our ability to operate this facility at certain performance levels that we believe are within our control to achieve. We also will be jointly responsible, along with our Ltd. joint venture partner, for the performance of sales and marketing services for the Ltd. through a 50%-owned and unconsolidated entity. The fixed-price components of the above-mentioned contracts were established based on estimates of expected construction, operation and maintenance costs. However, we are subject to variation in our expected profits or potential losses if the actual costs differ from the costs established in the contracts. Our maximum exposure to loss under these contracts cannot be quantified.

We determined that we are not the primary beneficiary of the Ltd. as all decision-making responsibility is shared jointly with our joint venture partner. As such, we do not have the power to individually direct the entity’s activities. Accordingly, we account for this investment under the equity method of accounting and do not consolidate this entity.

Investment in Refined Coal Facility — In January 2011, we acquired a noncontrolling interest in a limited liability company, which was established to invest in and manage a refined coal facility. Along with the other equity investor, we support the operations of the entity in exchange for a pro-rata share of the tax credits it generates. Our initial consideration for this investment consisted of a cash payment of $48 million. As of September 30, 2012 and December 31, 2011, our investment balance was $27 million and $35 million, respectively, representing our current maximum pre-tax exposure to loss. Under the terms and conditions of the transaction, we do not believe that we have any material exposure to loss. Future contributions will commence once certain levels of tax credits have been generated and will continue through the expiration of the tax credits under Section 45 of the Internal Revenue Code, which occurs at the end of 2019. We are only obligated to make future contributions to the extent tax credits are generated. We determined that we are not the primary beneficiary of this entity as we do not have the power to individually direct the entity’s activities. Accordingly, we account for this investment under the equity method of accounting and do not consolidate the entity. Additional information related to this investment is discussed in Note 5.

Investment in Federal Low-income Housing Tax Credits — In April 2010, we acquired a noncontrolling interest in a limited liability company established to invest in and manage low-income housing properties. We support the operations of the entity in exchange for a pro-rata share of the tax credits it generates. Our target return on the investment is guaranteed and, therefore, we do not believe that we have any material exposure to loss. Our consideration for this investment totaled $221 million, which was comprised of a $215 million note payable and an initial cash payment of $6 million. As of September 30, 2012 and December 31, 2011, our investment balance was $160 million and $178 million, respectively, and our debt balance was $158 million and $176 million, respectively. We determined that we are not the primary beneficiary of this entity as we do not have the power to individually direct the entity’s activities. Accordingly, we account for this investment under the equity method of accounting and do not consolidate the entity. Additional information related to this investment is discussed in Note 5.

Trusts for Final Capping, Closure, Post-Closure or Environmental Remediation Obligations — We have significant financial interests in trust funds that were created to settle certain of our final capping, closure, post-closure or environmental remediation obligations. Generally, we are the sole beneficiary of these 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. We have determined that these trust funds are variable interest entities; however, we are not the primary beneficiary of these entities because either (i) we do not have the power to direct the significant activities of the trusts or (ii) power over the trusts’ significant activities is shared.

We account for the trusts for which we are the sole beneficiary as long-term “Other assets” in our Condensed Consolidated Balance Sheet. These trusts had a fair value of $121 million at September 30, 2012 and $123 million at December 31, 2011. Our interests in the trusts that have been established for the benefit of both the Company and the host community in which we operate are accounted for as investments in unconsolidated entities and receivables. These amounts are recorded in “Other receivables,” “Investments in unconsolidated entities” and long-term “Other assets” in our Condensed Consolidated Balance Sheet, as appropriate. Our investments and receivables related to these trusts had an aggregate carrying value of $111 million as of September 30, 2012 and $107 million as of December 31, 2011. We reflect our interests in the unrealized gains and losses on available-for-sale securities held by these trusts as a component of “Accumulated other comprehensive income.”

As the party with primary responsibility to fund the related final capping, 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 assets of the trust. 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.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion should be read in conjunction with the Condensed Consolidated Financial Statements and notes thereto included under Item 1 and our Consolidated Financial Statements and notes thereto and related Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2011.

In an effort to keep our stockholders and the public informed about our business, we may make “forward-looking statements.” Forward-looking statements usually relate to future events and anticipated revenues, earnings, cash flows or other aspects of our operations or operating results. Forward-looking statements are often identified by the words, “will,” “may,” “should,” “continue,” “anticipate,” “believe,” “expect,” “plan,” “forecast,” “project,” “estimate,” “intend,” and words of similar nature and generally include statements containing:

Ÿ projections about accounting and finances;

Ÿ plans and objectives for the future;

Ÿ any projections of the amount, timing or impact of cost savings, restructuring actions, workforce reductions or related charges;

Ÿ projections or estimates about assumptions relating to our performance; or

Ÿ our opinions, views or beliefs about the effects of current or future events, circumstances or performance.

You should view these statements with caution. These statements are not guarantees of future performance, circumstances or events. They are based on the facts and circumstances known to us as of the date the statements are made. All aspects of our business are subject to uncertainties, risks and other influences, many of which we do not control. Any of these factors, either alone or taken together, could have a material adverse effect on us and could change whether any forward-looking statement ultimately turns out to be true. Additionally, we assume no obligation to update any forward-looking statement as a result of future events, circumstances or developments. The following discussion should be read together with the Condensed Consolidated Financial Statements and the notes thereto.

Some of the risks that we believe could affect our financial statements for 2012 and beyond and that could cause actual results to be materially different from those that may be set forth in forward-looking statements made by the Company include the following:

Ÿ competition may negatively affect our profitability or cash flows, our pricing strategy may have negative effects on volumes, and inability to execute our pricing strategy in order to retain and attract customers may negatively affect our average yield on collection and disposal business;

Ÿ we may fail in implementing our optimization and growth initiatives and overall business strategy, which could adversely impact our financial performance and growth;

Ÿ our restructuring may not achieve the goals and cost savings intended, implementing the restructuring may result in business disruption and employee distraction, and changes in our organizational structure and workforce could result in significant restructuring charges;

Ÿ regulations may negatively impact our business by, among other things, restricting our operations, increasing costs of operations or requiring additional capital expenditures;

Ÿ possible changes in our estimates of costs for site remediation requirements, final capping, closure and post-closure obligations, compliance and regulatory developments may increase our expenses;

Ÿ certain materials processed by our recycling operations are subject to significant commodity price fluctuations, as are methane gas, electricity and other energy-related products marketed and sold by our landfill gas recovery, waste-to-energy and independent power production plant operations; fluctuations in commodity prices may have negative effects on our operating results;

37

Ÿ increasing customer preference for alternatives to traditional disposal, government mandates requiring recycling and prohibiting disposal of certain types of waste, and overall reduction of waste generated could continue to have a negative effect on volumes of waste going to landfills and waste-to-energy facilities;

Ÿ developments in technology could trigger a fundamental change in the waste management industry, as waste streams are increasingly viewed as a resource, which may adversely impact volumes at our landfills and waste-to-energy facilities and our profitability;

Ÿ our existing and proposed service offerings to customers may require that we develop or license, and protect, new technologies; and our inability to obtain or protect new technologies could impact our services to customers and development of new revenue sources;

Ÿ adverse publicity (whether or not justified) relating to activities by our operations, employees or agents could tarnish our reputation and reduce the value of our brand;

Ÿ there is a risk of incurring significant environmental liabilities in the use, treatment, storage, transfer and disposal of waste materials; any substantial liability for environmental damage could have a material adverse effect on our financial condition and cash flows;

Ÿ weak economic conditions may negatively affect the volumes of waste generated;

Ÿ some of our customers, including governmental entities, have suffered financial difficulties that could affect our business and operating results, due to their credit risk and the impact of the municipal debt market on remarketing of our tax-exempt bonds;

Ÿ if we are unable to obtain and maintain permits needed to open, operate, and/or expand our facilities, our results of operations will be negatively impacted;

Ÿ fuel price increases or fuel supply shortages may increase our expenses and restrict our ability to operate;

Ÿ problems with the operation of current information technology or the development and deployment of new information systems could decrease our efficiencies and increase our costs;

Ÿ a cybersecurity incident could negatively impact our business and our relationships with customers;

Ÿ efforts by labor unions to organize our employees may increase operating expenses and we may be unable to negotiate acceptable collective bargaining agreements with those who have chosen to be represented by unions, which could lead to labor disruptions, including strikes and lock-outs, which could adversely affect our results of operations and cash flows;

Ÿ we could face significant liability for withdrawal from multiemployer pension plans;

Ÿ we are subject to operational and safety risks, including the risk of personal injury to employees and others;

Ÿ increased costs for financial assurance or the inadequacy of our insurance coverage could negatively impact our liquidity and increase our liabilities;

Ÿ possible charges as a result of shut-down operations, uncompleted development or expansion projects or other events may negatively affect earnings;

Ÿ we may reduce or suspend capital expenditures, acquisition activity, dividend declarations or share repurchases if we suffer a significant reduction in cash flows;

Ÿ we may be unable to incur future indebtedness on terms we deem acceptable or to refinance our debt obligations, including near-term maturities, on acceptable terms and higher interest rates and market conditions may increase our expense;

Ÿ climate change legislation, including possible limits on carbon emissions, may negatively impact our results of operations by increasing expenses;

We are the leading provider of comprehensive waste management services in North America. Our subsidiaries provide collection, transfer, recycling and disposal services. We are also a leading developer, operator and owner of waste-to-energy and landfill gas-to-energy facilities in the United States. Our customers include residential, commercial, industrial and municipal customers throughout North America.

Overview

Our Company is dedicated to three transformational goals that we believe will drive continued growth and leadership in a dynamic industry: know more about our customers and how to service them than anyone else; use conversion and processing technology to extract more value from the materials we manage; and continuously improve our operational efficiency. Our strategy supports diversion from landfills and converting waste into valuable products as customers seek more economically and environmentally sound alternatives. We intend to pursue achievement of our long-term goals in the short-term through efforts to:

Ÿ grow our markets by implementing customer-focused growth, through customer segmentation and through strategic acquisitions, while maintaining our pricing discipline and increasing the amount of recyclable materials we manage each year;

Ÿ grow our customer loyalty;

Ÿ grow into new markets by investing in greener technologies; and

Ÿ pursue initiatives that improve our operations and cost structure.

These efforts will be supported by ongoing improvements in information technologies. We believe that execution of our strategy will provide long-term value to our stockholders.

Highlights of our financial results for the current quarter include:

Ÿ Revenues of $3,461 million compared with $3,522 million in the third quarter of 2011, a decrease of $61 million, or 1.7%. This decrease in revenues is primarily attributable to:

Ÿ The continued decline in recyclable commodity prices which decreased our revenues by $176 million; partially offset by,

Ÿ Increases associated with acquired businesses of $95 million; and

39

Ÿ Internal revenue growth from yield on our collection and disposal business of 0.8%, or $22 million, in the current period, including a negative impact of 0.2%, or $5 million, from our waste-to-energy business, primarily as a result of lower disposal rates associated with the expiration and renegotiation of a long-term disposal contracts;

Ÿ Operating expenses of $2,229 million, or 64.4% of revenues, compared with $2,261 million, or 64.2% of revenues, in the third quarter of 2011. This decrease of $32 million is due primarily to a decrease in customer rebates because of lower recyclable commodity prices, partially offset by increases due to acquisitions and growth initiatives;

Ÿ Selling, general and administrative expenses decreased by $45 million, or 11.8%, from $380 million in the third quarter of 2011 to $335 million in the third quarter of 2012, largely due to reductions in our bonus and long-term incentive plan expenses;

Ÿ Income from operations of $500 million, or 14.4% of revenues, compared with $543 million, or 15.4% of revenues, in the third quarter of 2011; and

Ÿ Net income attributable to Waste Management, Inc. of $214 million, or $0.46 per diluted share, as compared with $272 million, or $0.58 per diluted share in the third quarter of 2011.

The comparability of our diluted earnings per share has been affected by the following items that occurred in the third quarter of 2012:

Ÿ Pre-tax costs aggregating $47 million related to our July 2012 restructuring and integration costs associated with our acquisition of Oakleaf, which had a negative impact of $0.06 on our diluted earnings per share;

Ÿ The recognition of impairment charges of $45 million, primarily associated with certain of our investments in unconsolidated entities and related assets, which had an unfavorable impact of $0.08 on our diluted earnings per share; and

Ÿ The recognition of a pre-tax charge of $6 million resulting from a union labor dispute in our Western Group, which had a negative impact of $0.01 on our diluted earnings per share.

Our third quarter of 2011 results were affected by the following:

Ÿ The recognition of pre-tax restructuring charges, excluding charges recognized in the operating results of Oakleaf, of $14 million related to our cost savings programs. These charges were primarily related to employee severance and benefit costs and had a negative impact of $0.02 on our diluted earnings per share;

Ÿ The recognition of net non-cash, pre-tax charges of $8 million arising from the accounting effect of lower ten-year Treasury rates, which are used to discount remediation reserves and related recovery assets at our landfills, offset in part by the favorable impact from a revision to an environmental remediation liability at a closed landfill. The net charges had a negative impact of $0.01 on our diluted earnings per share;

Ÿ The reduction in pre-tax earnings of approximately $6 million related to the Oakleaf acquisition, which includes the operating results of Oakleaf and related interest expense and integration costs. These items had a negative impact of $0.01 on our diluted earnings per share;

Ÿ The recognition of non-cash, pre-tax charges of $6 million related to impairments at two of our medical waste services facilities. The impairment charges had a negative impact of $0.01 on our diluted earnings per share; and

Ÿ The recognition of a tax benefit of $10 million due to favorable tax audit settlements and favorable adjustments relating to the finalization of our 2010 tax returns. These items had a positive impact of $0.02 on our diluted earnings per share.

We anticipate continued improvement in our pricing and cost savings initiatives, particularly our July 2012 restructuring activities; however, throughout the remainder of 2012, we expect to see a continued year-over-year

40

decline in recyclable commodity prices and from our waste-to-energy business. Because commodity markets are inherently volatile, this prediction could materially change if markets either improve or deteriorate beyond our current predictions.

Free Cash Flow — As is our practice, we are presenting free cash flow, which is a non-GAAP measure of liquidity, in our disclosures because we use this measure in the evaluation and management of our business. We define free cash flow as net cash provided by operating activities, less capital expenditures, plus proceeds from divestitures of businesses (net of cash divested) and other sales of assets. We believe it is indicative of our ability to pay our quarterly dividends, repurchase common stock, fund acquisitions and other investments and, in the absence of refinancings, to repay our debt obligations. Free cash flow is not intended to replace “Net cash provided by operating activities,” which is the most comparable U.S. GAAP measure. However, we believe free cash flow gives investors useful insight into how we view our liquidity. Nevertheless, the use of free cash flow as a liquidity measure has material limitations because it excludes certain expenditures that are required or that we have committed to, such as declared dividend payments and debt service requirements.

Our calculation of free cash flow and reconciliation to “Net cash provided by operating activities” is shown in the table below (in millions), and may not be calculated the same as similarly-titled measures presented by other companies:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2012			2011			2012			2011
Net cash provided by operating activities	$	574		$	659		$	1,718		$	1,737
Capital expenditures		(402	)		(313	)		(1,132	)		(909	)
Proceeds from divestitures of businesses (net of cash divested) and other sales of assets(a)		8			26			28			39
Free cash flow	$	180		$	372		$	614		$	867

(a) Proceeds from divestitures of businesses for the three and nine months ended September 30, 2011 includes the receipt of a payment of $17 million related to a note receivable from a prior year divestiture. This receipt is included as a component of “Other” within “Cash flows from investing activities” in our Condensed Consolidated Statement of Cash Flows.

When comparing our cash flow from operating activities for the three and nine months ended September 30, 2012 to the comparable periods in 2011, the decrease was primarily related to the payment of $59 million to settle the liabilities associated with the termination of forward-starting swaps in September 2012, as well as the impact of lower cash earnings and the unfavorable impacts of working capital changes. These decreases were partially offset by a decrease in tax payments of $70 million for the nine months ended September 30, 2012 as compared with the nine months ended September 30, 2011 and a favorable cash receipt of $72 million resulting from the termination of interest rate swaps in April 2012.

The increase in capital expenditures when comparing the nine months ended September 30, 2012 with the prior year period can generally be attributed to increased spending on compressed natural gas vehicles, related fueling infrastructure and growth initiatives, and the impact of timing differences associated with cash payments for the previous years’ fourth quarter capital spending. We generally use a significant portion of our free cash flow on capital spending in the fourth quarter of each year. A more significant portion of our fourth quarter 2011 spending was paid in cash in 2012 than in the preceding year.

Acquisition of Oakleaf — On July 28, 2011, we paid $432 million, net of cash received of $4 million and inclusive of certain adjustments, to acquire Oakleaf. Oakleaf provides outsourced waste and recycling services principally through a nationwide network of third-party haulers. The operations we acquired generated approximately $580 million in revenues in 2010. We acquired Oakleaf to advance our growth and transformation strategies and increase our national accounts customer base while enhancing our ability to provide comprehensive environmental solutions. For the year ended December 31, 2011, we incurred $1 million of

41

acquisition-related costs, which were classified as “Selling, general and administrative” expenses. For the three- and nine-month periods ended September 30, 2012, Oakleaf recognized revenues of $143 million and $438 million, respectively, and net losses of $4 million and $8 million, respectively. These amounts are included in our Condensed Consolidated Statement of Operations.

The following pro forma consolidated results of operations for the three and nine months ended September 30, 2011 have been prepared as if the acquisition of Oakleaf occurred at January 1, 2011 (in millions, except per share amounts):

	Three Months  Ended September 30, 2011		Nine Months  Ended September 30, 2011
Operating revenues	$	3,566	$	10,287
Net income attributable to Waste Management, Inc.		272		689
Basic earnings per common share		0.58		1.46
Diluted earnings per common share		0.58		1.45

Adoption of New Accounting Pronouncements

Fair Value Measurement — In May 2011, the Financial Accounting Standards Board (“FASB”) amended authoritative guidance associated with fair value measurements. This amended guidance defines certain requirements for measuring fair value and for disclosing information about fair value measurements in accordance with U.S. generally accepted accounting principles. The amendments to authoritative guidance associated with fair value measurements were effective for the Company on January 1, 2012 and have been applied prospectively. The adoption of this guidance did not have a material impact on our consolidated financial statements.

Comprehensive Income — In June 2011, the FASB issued amended authoritative guidance associated with comprehensive income, which requires companies to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. This update eliminates the option to present the components of other comprehensive income as part of the statement of changes in equity. In December 2011, the FASB deferred the effective date of the specific requirement to present items that are reclassified out of accumulated other comprehensive income to net income alongside their respective components of net income and other comprehensive income. The amendments to authoritative guidance associated with comprehensive income were effective for the Company on January 1, 2012 and have been applied retrospectively. The adoption of this guidance did not have a material impact on our consolidated financial statements.

Critical Accounting Estimates and Assumptions

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 present the greatest amount of uncertainty relate to our accounting for landfills, environmental remediation liabilities, asset impairments, deferred income taxes and reserves associated with our insured and self-insured claims, as described in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2011. Actual results could differ materially from the estimates and assumptions that we use in the preparation of our financial statements.

In the second quarter of 2012, we believed that the fair value of our Wheelabrator Group could potentially be less than its carrying amount because of the negative effect on our revenues of the continued deterioration of electricity commodity prices, coupled with our continued increased exposure to market prices as a result of the expiration of several long-term, fixed-rate electricity commodity contracts at our waste-to-energy and

42

independent power facilities, and the expiration of several long-term disposal contracts at above-market rates. As a result, we performed an interim impairment analysis of our Wheelabrator Group’s goodwill balance, which was $788 million as of June 30, 2012.

We performed an interim quantitative assessment using both an income and a market approach, which indicated that the estimated fair value of our Wheelabrator Group exceeded its carrying value; however, the amount by which the fair value exceeded the carrying value declined significantly from the most recent annual impairment test performed at October 1, 2011. At that time, our Wheelabrator Group’s estimated fair value exceeded its carrying value by approximately 30%, as compared with slightly greater than 10% as of the interim impairment test performed in the second quarter of 2012. If market prices for electricity worsen or do not recover as we have projected, if our disposal rates continue to decline, or if our costs and capital expenditures exceed our forecasts, the estimated fair value of our Wheelabrator Group could decrease further and potentially result in an impairment charge in a future period. We continue to monitor our Wheelabrator Group for possible impairment of their goodwill balance.

Results of Operations

Operating Revenues

Through the third quarter of 2012, we managed and evaluated our principal operations through our Eastern, Midwest, Southern, Western and Wheelabrator Groups. These five Groups are our reportable segments. Our four geographic operating Groups provide collection, transfer, disposal (in both solid waste and hazardous waste landfills) and recycling services for residential, commercial, industrial and municipal customers throughout North America. Our fifth Group is the Wheelabrator Group, which provides waste-to-energy services and manages waste-to-energy facilities and independent power production plants in the United States and through investments in China and Europe. In addition, the Oakleaf operations we acquired on July 28, 2011 represent a separate operating segment; however, they do not meet the criteria to be presented as a separate reportable segment.

We also provide additional services that are not managed through our five Groups, including the Oakleaf operations referenced above, recycling brokerage services, electronic recycling services, in-plant services, landfill gas-to-energy services, integrated medical waste services and expanded service offerings and solutions. Part of our expansion of services includes offering portable self-storage services and fluorescent bulb and universal waste mail-back through our LampTracker^® program. In addition, we have made investments that involve the acquisition and development of interests in oil and gas producing properties. These operations are presented as “Other” in the table below.

In July 2012, we announced a reorganization of our operations, designed to streamline management and staff support and reduce our cost structure, while not disrupting our front-line operations. We are in the process of implementing the reorganization, which includes the elimination of our four existing geographic Groups, and we expect it to be completed by the end of 2012. Once the reorganization has been completed, our reportable segments will be realigned to conform with our new management structure. Refer to Note 10 to the Condensed Consolidated Financial Statements for more information related to this reorganization.

Total Company	$	3,521	$	9,970

(ii) Average revenue growth from yield for “Collection and disposal” excludes all electricity-related revenues generated by our Wheelabrator Group, which are reported as “Electricity” revenues.

Our revenues decreased $61 million, or 1.7%, during the three months ended September 30, 2012 as compared with the prior year period. This decrease was primarily driven by a decline in recyclable commodity prices, which was partially offset by revenue growth from acquisitions and yield on our collection and disposal lines of business. Our revenue growth from acquisitions includes $44 million from our acquisition of Oakleaf. Note that the overall rate of revenue growth due to acquisitions for the three months ended September 30, 2012 has decreased significantly as compared to previous quarters in 2012 as a result of the anniversary of our Oakleaf acquisition at the end of July 2012.

Our revenues increased $243 million, or 2.4%, for the nine months ended September 30, 2012 as compared with the prior year period. During the nine-month period, our revenue growth has been driven by (i) acquisitions, particularly the acquisition of Oakleaf, which increased consolidated revenues $314 million for the nine months ended September 30, 2012, (ii) increased collection and disposal average yield, and (iii) increased volume. Offsetting these revenue increases were market factors, including lower recyclable commodity prices, primarily driven by the continued increase in supply and lower demand; lower electricity prices and foreign currency translation. Electricity prices correlate with natural gas prices and cause fluctuations in the rates we receive for electricity under our power purchase contracts and merchant transactions. Foreign currency translation affects revenues from our Canadian operations.

The following provides further details associated with our period-to-period change in revenues.

Average yield

Collection and disposal average yield — This measure reflects the effect on our revenue from the pricing activities of our collection, transfer, landfill and waste-to-energy disposal operations, exclusive of volume changes. Revenue growth from collection and disposal average yield includes not only base rate changes and environmental and service fee increases, but also (i) certain average price changes related to the overall mix of services, which are due to both the types of services provided and the geographic locations where our services are provided; (ii) changes in average price from new and lost business; and (iii) price decreases to retain customers.

Our revenue growth from yield on our collection and disposal lines of business was $22 million, or 0.8%, and $60 million, or 0.7%, for the three and nine months ended September 30, 2012, respectively. This increase in revenue from yield was primarily driven by our collection operations, particularly in our commercial and industrial lines of business. Our overall revenue growth from yield in our residential line of business improved

46

for the quarter ended September 30, 2012 and was favorable for the first nine months of 2012. However, our Eastern and Southern Groups continued to experience downward pressure on our revenue growth from yield in our residential line of business, where we experienced negative revenue growth from yield for the first nine months of 2012. Due to competition, it is increasingly difficult to retain customers and to win new contracts at current average rates; as a result, in many instances, the Company has offered increased services without a commensurate increase in pricing when bidding on or renewing residential contracts and pursuing residential subscription business. These increased services are principally recycling services, which are typically priced lower than our average rates. This combination of increased competition and bundling of complementary services, such as recycling, in the residential line of business has put added pressure on our revenue growth from yield.

For the three and nine months ended September 30, 2012, our total collection and disposal revenue growth from yield was negatively affected by $7 million and $24 million, respectively, as a result of the expiration and renegotiation of a long-term disposal contract in August 2011 at one of our waste-to-energy facilities in South Florida. Certain of the franchise agreements serviced by our collection companies in South Florida contain specific language that ties a portion of their total rate to the disposal rate charged by this waste-to-energy facility to our collection companies. The expiration and renegotiation of this contract decreased revenues both in our waste-to-energy disposal line of business, by approximately $5 million and $17 million for the three and nine months ended September 30, 2012, and in our collection line of business, by approximately $2 million and $7 million for the three and nine months ended September 30, 2012, respectively. Additionally, for the three and nine months ended September 30, 2012, we experienced further downward pressure on our revenue growth from yield in our waste-to-energy disposal line of business of approximately $2 million and $4 million, respectively, resulting from the expiration and renegotiation of a second similar long-term waste-to-energy disposal contract in South Florida at the end of March 2012.

Revenues from our environmental fee, which are included in average revenue growth from yield on collection and disposal, increased $8 million and $40 million for the three and nine months ended September 30, 2012, respectively. These revenues were $90 million and $257 million for the three and nine months ended September 30, 2012 as compared with $82 million and $217 million for the three and nine months ended September 30, 2011, respectively.

Recycling commodities — Decreases in the prices of recyclable commodities resulted in a decline in revenues of $176 million and $345 million, with an estimated negative impact on income from operations of approximately $60 million and $100 million, for the three and nine months ended September 30, 2012, respectively. During the fourth quarter of 2011, we saw commodity prices decline 4% as compared with the prior year. During the first nine months of 2012, we saw the downward trend continue as year-over-year commodity prices declined almost 30%, driven by the continued increase in supply and lower demand.

Fuel surcharges and mandated fees — These revenues, which are predominantly generated by our fuel surcharge program, increased by $8 million and $17 million over the comparable prior year periods during the three and nine months ended September 30, 2012, respectively. This increase is directly attributable to higher national average prices for diesel fuel that we use for our fuel surcharge program and increased mandated fees, which are primarily related to the pass-through of fees and taxes assessed by various state, county and municipal governmental agencies at our landfills and transfer stations.

Volume

Changes in our volume caused our revenues to decrease $5 million and increase $53 million during the three and nine months ended September 30, 2012, respectively, as compared with the same prior year periods. The current quarter revenue decline due to volume was primarily driven by one less workday in the current period as compared with the prior year period. Nevertheless, this is a notable improvement from 2011 when lower volumes caused our revenue to decrease $64 million and $167 million as compared with the three and nine months ended September 30, 2010, respectively.

47

Our total landfill revenues increased $12 million and $42 million for the three and nine months ended September 30, 2012, respectively, over the comparable prior year periods due to higher third-party volumes, primarily driven by higher special waste volumes in our Eastern and Midwest geographic Groups. In addition, revenues increased from year-over-year volume growth in our recycling brokerage business and our material recovery facilities by $13 million and $26 million for the three and nine months ended September 30, 2012, respectively. The additional recycling capacity that we added during 2011 and 2012, as well as our continued pursuit of municipal volumes, contributed to these increases in revenues due to volume.

Volume declines from our collection business accounted for a $35 million revenue decline during the nine months ended September 30, 2012, which we experienced entirely in the second and third quarters of 2012. The decline was primarily driven by our commercial and, to a lesser extent, our residential collection lines of business, which we attribute to the effects of pricing, competition and diversion of waste by customers, as well as the overall continued weakness in the economy. Revenue declines due to lower volumes in these two collection lines of business were offset, in part, by revenue increases in our industrial collection line of business, driven in large part by the growth of our oilfield services business in our Eastern Group. Additionally, during the nine months ended September 30, 2012, revenue increased due to volume growth in our non-traditional collection businesses, as well as in our ancillary services, primarily driven by increases in our medical waste services, our in-plant services and our portable self-storage services businesses.

Acquisitions

Revenues increased $95 million and $490 million for the three and nine months ended September 30, 2012, respectively, due to acquisitions. The increase was principally associated with our acquisition of Oakleaf, which is reported in our “Other” line of business. Additionally, acquisitions increased our revenues in the current period in our collection line of business, due in part to our oilfield services business in our Eastern Group, and in our recycling line of business. These acquisitions demonstrate our focus on identifying strategic growth opportunities in new, complementary lines of business. Note that the rate of revenue growth due to acquisitions for the three months ended September 30, 2012 has decreased significantly as compared to previous quarters in 2012 as a result of the anniversary of our Oakleaf acquisition at the end of July 2012.

Operating Expenses

Our operating expenses decreased by $32 million, or 1.4%, and increased by $259 million, or 4.0% for the three and nine months ended September 30, 2012 as compared with the three and nine months ended September 30, 2011, respectively. Our operating expenses as a percentage of revenues increased from 64.2% in the third quarter of 2011 to 64.4% in the current quarter, and increased from 64.1% for the nine months ended September 30, 2011 to 65.1% for the nine months ended September 30, 2012. The changes in our operating expenses during the three and nine months ended September 30, 2012 can largely be attributed to the following:

Ÿ Acquisitions and growth initiatives — We have experienced cost increases attributable to recently acquired businesses and, to a lesser extent, our various growth and business development initiatives, although much of this impact began to anniversary during the third quarter of 2012. The increase in operating expenses resulting from acquired businesses was more than offset by increased revenues from acquired businesses. Recent acquisitions include Oakleaf, a number of collection operations, including oilfield services in our Eastern Group, and several recycling operations. These cost increases affected each of the operating cost categories identified in the table below and were the main driver of our total increase in operating expenses for the nine months ended September 30, 2012. In particular, the acquisition of Oakleaf increased operating costs by $35 million in the current quarter and $263 million for the nine months ended September 30, 2012, primarily increasing subcontractor costs and, to a lesser extent, the cost of goods sold and other categories;

Ÿ Volume changes — During the three and nine months ended September 30, 2012, we experienced an increase in variable costs attributable to higher volumes in certain lines of business, particularly our recycling, industrial collection and non-traditional collection businesses. In our non-traditional collection businesses, we experienced volume increases primarily in our in-plant services and largely during the first

48

quarter. We continue to manage our fixed costs and control our variable costs as we experience volume increases and decreases. Note that during the third quarter 2012, collection volumes decreased slightly and, as a result, we were able to reduce related variable costs as compared with the third quarter of 2011. These cost fluctuations due to volume have impacted each of the operating cost categories identified in the table below; and

Ÿ Lower market prices for recyclable commodities — Overall, market prices for recyclable commodities decreased on a year-over-year basis by approximately 40% and 30% for the three and nine months ended September 30, 2012, respectively, as a result of the continued decrease in recyclable commodity market prices that began during late 2011 from the near-historic highs reached during the second and third quarters of 2011. This decrease in market prices was the primary driver of the current quarter and year-to-date decrease in cost of goods sold, primarily customer rebates, and has also resulted in decreased revenues and earnings during the current year.

The following table summarizes the major components of our operating expenses, which include the impact of foreign currency translation, for the three- and nine-month periods ended September 30 (dollars in millions):

	Three Months Ended September 30,				Period-to- Period Change					Nine Months Ended September 30,				Period-to- Period Change
	2012		2011							2012		2011
Labor and related benefits	$	595	$	598	$	(3	)	(0.5	)%	$	1,793	$	1,743	$	50		2.9	%

	$	2,229	$	2,261	$	(32	)	(1.4	)%	$	6,655	$	6,396	$	259		4.0	%

In addition to the significant items noted above, other factors contributing to the changes in our operating expenses are discussed below:

Ÿ Labor and related benefits — The year-to-date increase was largely due to (i) additional employee expenses incurred as a result of acquisitions and growth opportunities; (ii) higher hourly and salaried wages due to merit increases effective April 2011 and increases stipulated in union labor agreements; and (iii) a non-cash charge incurred during the three months ended June 30, 2012 by our Eastern Group as a result of our partial withdrawal from an underfunded multiemployer pension plan in New England. Note that during the current quarter, labor costs were slightly lower than the prior year period, reversing the trend of the year-over-year increases seen in the first and second quarters of 2012. This was partially the result of (i) the anniversary of a number of acquisitions during the current quarter, including Oakleaf, which reduced the impacts of year-over-year cost increases as a result of acquisitions compared to recent quarters, (ii) lower year-to-date bonus expense in 2012 when compared with 2011; and (iii) one less workday in the current quarter than in the third quarter of 2011.

Ÿ Maintenance and repairs — The increase was primarily due to (i) higher costs in our geographic Groups, largely attributable to increased fleet maintenance costs, (ii) differences in the timing and scope of planned maintenance projects at our waste-to-energy facilities, principally during the first quarter, a portion of which was offset by an increase in revenues related to the reimbursement of certain of these costs by a municipality, and (iii) an increase in container maintenance costs as a result of our third quarter 2011 acquisition of Oakleaf. Our fleet maintenance costs include services provided by third parties, tires,

49

parts and internal shop labor costs. The increase in expense for tires and parts reflects the worldwide increase in related commodity prices. Through our Oakleaf acquisition, we operate a nationwide compactor leasing business (Greenleaf Compaction) which has increased our container maintenance costs in the current year when compared with the nine months ended September 30, 2011.

Ÿ Subcontractor costs — The current year increase in subcontractor costs was primarily a result of the Oakleaf acquisition and, to a much lesser extent, (i) other recent acquisitions, (ii) our various growth and business development initiatives, primarily associated with servicing our in-plant services and healthcare solutions customers, and (iii) as discussed further below, higher fuel prices, which resulted in an increase in the fuel component of our subcontractor costs during the current year. Oakleaf principally utilizes a nationwide network of third-party haulers to service its customers. As a result, this acquisition increased our subcontractor costs by $32 million and $213 million for the current quarter and year-to-date as compared with the three- and nine-month periods of 2011, respectively.

Ÿ Fuel — On average, diesel fuel prices increased 3.1% from $3.84 per gallon for the nine months ended September 30, 2011 to $3.96 per gallon for the nine months ended September 30, 2012. Higher fuel costs experienced during the current year caused increases in both our direct fuel costs and in the fuel component of our subcontractor costs as compared with the nine months ended September 30, 2011. Increased revenues attributable to our fuel surcharge largely offset the higher fuel costs incurred during the current year.

Ÿ Landfill operating costs — The decrease in these costs during the current year was due largely to:

Ÿ The prior year recognition of an unfavorable adjustment of $17 million during the three and nine months ended September 30, 2011, due to a decrease from 3.50% to 2.00% in United States Treasury rates used as the discount rate to estimate the present value of our environmental remediation obligations and recovery assets; and

Ÿ Additional landfill site costs experienced along the East Coast during the second and third quarters of 2011, which were due to significant rainfall events, including the effects from spring flooding in the second quarter and Hurricane Irene and Tropical Storm Lee during the third quarter; partially offset by

Ÿ The third quarter 2011 recognition of a $9 million favorable revision to an environmental liability at a closed site based on the estimated cost of the remediation alternative selected by the EPA.

Ÿ Other — The current year increase was due to our Oakleaf acquisition, other recent acquisitions and our various growth and business development initiatives. The increase from our various initiatives is associated with the rental of facilities and equipment for these operations. The current quarter included additional costs associated with a union labor dispute in Seattle, which also contributed to the current year increase in this category for the three and nine months ended September 30, 2012.

Selling, General and Administrative

Our selling, general and administrative expenses decreased by $45 million, or 11.8%, and $28 million, or 2.4%, when comparing the three and nine months ended September 30, 2012 with the comparable prior year periods, respectively. As a percentage of revenue, our selling, general and administrative expenses decreased from 10.8% for the third quarter of 2011 to 9.7% for the third quarter of 2012, and decreased from 11.5% for the nine months ended September 30, 2011 to 10.9% for the nine months ended September 30, 2012. The most significant items affecting the year-over-year comparison of selling, general and administrative costs for the three and nine months ended September 30, 2012 include the following:

Ÿ A decrease in bonus expense of $44 million and $57 million, respectively, and a decrease in non-cash compensation expense attributable to our long-term incentive plan, or LTIP, of $4 million and $15 million, respectively;

Ÿ A decrease in consulting costs of $5 million and $26 million, respectively. We incurred higher consulting costs in 2011 during the start-up phase of our company-wide initiatives focusing on procurement, operational and back-office efficiency. However, the decrease in consulting costs was partially offset by

50

additional costs associated with our efforts to implement these initiatives. These additional costs were principally labor-related and resulted in increases of $1 million and $10 million for the three- and nine-month comparisons, respectively; and

Ÿ Our acquisition of Oakleaf, which increased costs by $5 million and $36 million, respectively. The year-over-year impact of Oakleaf has decreased significantly as compared with previous quarters in 2012 as a result of the anniversary of the acquisition at the end of July 2012.

In addition, in July 2012, we announced a reorganization of our operations, designed to streamline management and staff support and reduce our cost structure, while not disrupting our front-line operations. We are in the process of implementing the reorganization and we expect it to be completed by the end of 2012. During the three and nine months ended September 30, 2012, we realized labor and related benefits cost savings of $6 million.

The following table summarizes the major components of our selling, general and administrative expenses for the three- and nine-month periods ended September 30 (dollars in millions):

	Three Months									Nine Months
	Ended				Period-to- Period Change					Ended				Period-to- Period Change
	September 30,									September 30,
	2012		2011							2012		2011
Labor and related benefits	$	187	$	233	$	(46	)	(19.7	)%	$	643	$	676	$	(33	)	(4.9	)%
Professional fees		35		39		(4	)	(10.3	)		122		146		(24	)	(16.4	)

	$	335	$	380	$	(45	)	(11.8	)%	$	1,116	$	1,144	$	(28	)	(2.4	)%

Other significant changes in our selling, general and administrative expenses are discussed below:

Ÿ Labor and related benefits — During the three and nine months ended September 30, 2012 we experienced higher expenses associated with our executive salary deferral plan, which are directly affected by equity-market conditions. During the nine months ended September 30, 2012, compensation expense was higher than the same prior year period due to average headcount increases from the acquisition of Oakleaf and the company-wide initiatives mentioned above, as well as our sales and marketing initiatives. However, compensation expense was lower in the third quarter of 2012 as compared with the same prior year period as a result of the savings realized from our July 2012 restructuring activities.

Ÿ Provision for bad debts — During the current quarter, our provision for bad debts decreased due in part to the unfavorable impact of a reserve recorded in 2011 associated with the bankruptcy of one of our recycling paper mill customers. The current quarter decrease was more than offset during the nine months ended September 30, 2012, as a result of (i) increased collection risk resulting from work we are performing in certain new businesses in our Eastern Group; (ii) collection issues we are experiencing in our Puerto Rico operations in our Southern Group; and (iii) increases due to our Oakleaf acquisition.

Ÿ Other — In 2012, we experienced increases in our (i) travel and entertainment costs to support our strategic efforts; (ii) building and equipment costs, which include rental and utilities; (iii) computer and telecommunications costs, due in part to improvements we are making to our information technology systems; and (iv) litigation settlement costs, principally noted in the three-month comparison.

51

Depreciation and Amortization

The following table summarizes the components of our depreciation and amortization expense for the three- and nine-month periods ended September 30 (dollars in millions):

	Three Months Ended September 30,				Period-to- Period-to-Period Change				Nine Months Ended September 30,				Period-to- Period-to-Period  Change
	2012		2011						2012		2011
Depreciation of tangible property and equipment	$	207	$	200	$	7	3.5	%	$	622	$	599	$	23		3.8	%
Amortization of landfill airspace		107		103		4	3.9			297		300		(3	)	(1.0	)
Amortization of intangible assets		17		14		3	21.4			52		36		16		44.4
	$	331	$	317	$	14	4.4	%	$	971	$	935	$	36		3.9	%

The increase in amortization expense of intangible assets in 2012 is due to our focus on the growth and development of our business through acquisitions and other investments. The increase is primarily related to the amortization of customer lists, which were acquired through our acquisition of Oakleaf and various collection and recycling operations.

Restructuring

2012 Restructurings—In July 2012, we announced a reorganization of operations, designed to streamline management and staff support and reduce our cost structure, while not disrupting our front-line operations. Principal organizational changes being implemented include removal of the management layer consisting of our four existing geographic Groups; consolidation and reduction of the number of Areas managing the core collection, disposal and recycling businesses from 22 to 17; and reduction of corporate support staff in an effort to better align support with the needs of the operating units.

We are in the process of implementing this restructuring plan and we expect it to be completed by the end of 2012. We currently estimate that approximately 700 employee positions throughout the Company, including positions at both the management and support levels, will be eliminated. Voluntary separation arrangements were offered to many in certain levels of management.

Additionally, during the first nine months of 2012, we recognized employee severance and benefits restructuring charges associated with the reorganization of Oakleaf that began in 2011 and certain other actions taken by the Company in early 2012.

During the third quarter of 2012, we recognized pre-tax charges of $44 million associated with these restructuring activities, $39 million of which related to employee severance and benefit costs. The remainder of the charge was primarily related to abandoned operating leases. We currently expect to incur additional restructuring charges in the fourth quarter of 2012, consisting of employee severance and benefits expenses and facility, lease and other related expenses, in the range of $20 million to $30 million. The additional restructuring charges are an estimate, and actual charges may vary materially based on various factors, including the number of employee terminations; facility, lease or other restructuring charges that are not yet estimable; and changes in management’s objectives.

2011 Restructurings—Beginning in July 2011, we took steps to streamline our organization as part of our cost savings programs. This reorganization eliminated over 700 employee positions throughout the Company, including approximately 300 open positions. Additionally, subsequent to our acquisition of Oakleaf, we incurred charges in connection with restructuring that organization. During the year ended December 31, 2011, we recognized a total of $19 million of pre-tax restructuring charges, of which $18 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.

52

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

During the third quarter of 2012, we recognized impairment charges aggregating $21 million, relating in large part to (i) the impairment of a note receivable from an entity that we invested in that is now being liquidated (see “Equity in net losses of unconsolidated entities”discussion below), (ii) the impairment of certain related technology assets due to our decision not to use or develop those assets and (iii) the impairment of an oil and gas well as a result of projected operating losses that caused us to write-down the carrying value of the oil and gas well to its estimated fair value. These charges are included in our “Other” operations in Note 8.

Additionally, we are in the process of evaluating opportunities associated with the sale or discontinued use of underperforming assets or assets that may no longer meet our strategic objectives. Accordingly, it is possible that additional impairments may be recorded as assets are sold or become held-for-sale.

During the second quarter of 2012, we recognized impairment charges of $34 million, relating primarily to two facilities in our medical waste services business as a result of projected operating losses at each of these facilities. We wrote down the carrying values of the facilities’ operating permits and property, plant and equipment to their estimated fair values. Our medical waste services business is included in our “Other” operations in Note 8.

During the third quarter of 2011, we recognized impairment charges relating to two facilities in our medical waste services business, in addition to the two facilities impaired in the second quarter and discussed above, as a result of the closure of one site and as a result of continuing operating losses at the other site. We wrote down the net book values of the sites to their estimated fair values.

Income from Operations by Reportable Segment

Reportable Segments — The most significant items affecting the results of operations of our four geographic Groups during the three and nine months ended September 30, 2012 as compared with the prior year periods are summarized below:

Ÿ A decrease in recyclable commodity prices with an estimated impact on income from operations of approximately $60 million and $100 million for the three and nine months ended September 30, 2012, respectively;

Ÿ Revenue growth from yield on our base business of approximately $91 million, noted particularly in our Midwest and Western Groups and, to a lesser extent, in our Southern Group. Our Eastern Group

53

experienced favorable revenue growth from yield on its base business during the nine months ended September 30, 2012; however, revenue growth from yield declined slightly during the third quarter of 2012;

Ÿ The accretive benefits of recent acquisitions, particularly in our Eastern Group;

Ÿ Restructuring charges recognized during the third quarter of 2012;

Ÿ Higher maintenance and repair costs of approximately $29 million during the nine months ended September 30, 2012; although the impact in our Eastern Group was principally during the first quarter of 2012;

Ÿ An increase of $14 million in fuel costs during the nine months ended September 30, 2012, consisting of an increase of $18 million in the first quarter of 2012, offset to a small extent by a decrease of $4 million in the second quarter of 2012. This net increase in fuel costs during the first half of 2012 outpaced the related revenue growth from our fuel surcharge program. During the third quarter of 2012, fuel costs were approximately the same as during the third quarter of 2011; and

Ÿ Lower salaries and wages due to the transfer of certain field customer service employees from our reportable segments to Corporate and Other. The decreases during the nine months ended September 30, 2012 were offset, in part, by higher salaries and wages during the first quarter of 2012 due to annual merit increases effective April 2011 for salaried and hourly employees.

The significant decrease in income from operations of our Wheelabrator Group for the three and nine months ended September 30, 2012 as compared with the respective prior year periods was driven largely by (i) lower revenues due to the expiration of long-term contracts at certain of our waste-to-energy facilities; (ii) lower energy pricing at our merchant facilities; and (iii) increased international development costs.

Other significant items affecting the comparability of our Groups’ results of operations for the three and nine months ended September 30, 2012 and 2011 are summarized below:

Eastern — The Eastern Group’s revenues and income from operations for the three and nine months ended September 30, 2012 as compared with the prior year periods were favorably affected by the growth of our oilfield services business. These services, which focus principally on the hauling and disposal of drill cuttings and fluids and various well pad services, favorably affected both our landfill and collection lines of business. Further favorably affecting the Group’s income from operations was (i) a decrease in landfill amortization expense, which was principally due to both a decline in rates relating to the addition of expansion airspace at one of our landfills in the third quarter of 2011 and a nonrecurring amortization expense adjustment recognized in the second quarter of 2011 at a separate landfill; and (ii) higher landfill site costs in the prior year for the collection and disposal of leachate, which was largely the result of significant rainfall events during the second and third quarters of 2011. These favorable impacts were offset, in part, by the recognition of a non-cash charge in June 2012 resulting from the partial withdrawal from an underfunded multiemployer pension plan in New England.

Midwest — The income from operations for our Midwest Group for the nine months ended September 30, 2012 as compared with the prior year period was driven in part by improvement in landfill special waste volumes experienced during the first quarter of 2012.

Southern — The Southern Group’s income from operations was impacted by an improvement in landfill volumes, driven in part by our oilfield services business, and a $3 million increase in bad debt expense recognized during the quarter ended June 30, 2012 as a result of collection issues in Puerto Rico. The comparability of the Group’s year-over-year results was further affected by a charge of $11 million during the nine months ended September 30, 2011 related to a litigation reserve. The litigation reserve was the result of a court judgment issued in a litigation matter related to our Southern Group; however, due to the timing of the judgment, the reserve was recorded after the general ledgers of our operating segments for the year 2010 were closed. As a result, the charge was initially recorded and reported in “Other” and reflected in our consolidated operating measures in the fourth quarter of 2010. In the first quarter of 2011, the charge was reversed out of “Other” and recorded in the appropriate reportable segment.

54

Western — The income from operations of our Western Group for the nine months ended September 30, 2012 was negatively affected by $6 million of additional operating expenses incurred as a result of a union labor dispute in Seattle.

Significant items affecting the comparability of the remaining components of our results of operations for the three and nine months ended September 30, 2012 and 2011 are summarized below:

Other — It is our policy to report adjustments that are recorded after the closing date of our reportable segment ledgers in “Other” when they are initially recorded. We then report these late adjustments in the appropriate reportable segment in the next reporting period, with a corresponding reversal out of “Other.”

The favorable change in operating results during the three months ended September 30, 2012 as compared to the prior year period is largely due to a late favorable adjustment recorded in the third quarter of 2012 to reduce bonus expense for our reportable segments. The favorable change during the three months ended September 30, 2012 was offset, in part, by impairment charges associated with a note receivable from an entity that we invested in that is now being liquidated and an oil and gas well.

The unfavorable change in operating results during the nine months ended September 30, 2012 as compared with the prior year period is largely due to (i) impairment charges recognized during 2012 relating primarily to two facilities in our medical waste services business, a note receivable from an entity that we invested in that is now being liquidated and an oil and gas well; (ii) costs associated with our Waste Management Sustainability Services business, which includes both our historical national accounts customers and the customers acquired through Oakleaf, and (iii) the reversal in 2011 of expense adjustments related to our reportable segments that were initially reported in “Other” in the fourth quarter of 2010. These expense adjustments were reported in the applicable reportable segment in the first quarter of 2011. The most significant adjustment reversed out of “Other” in the first quarter of 2011 was $11 million of additional expense for litigation reserves in our Southern Group, as discussed above. The unfavorable change during the nine months ended September 30, 2012 was offset, in part, by the favorable effect of late adjustments recorded in the third quarter of 2012 to reduce bonus expense for our reportable segments.

Corporate and Other — The increase in expenses during the three and nine months ended September 30, 2012 is the result of cost increases attributable to (i) additional compensation expense due to transfers of certain field customer service employees to our Corporate sales organization; (ii) restructuring charges recognized during the third quarter of 2012; and (iii) headcount increases due to our sales and marketing initiatives and implementation of our company-wide initiatives focusing on procurement, operational and back-office efficiency. These increases were partially offset by (i) a reduction in bonus expense; (ii) a decrease in professional fees, primarily due to the discontinuation of consulting services and related fees incurred during 2011 associated with the start-up phase of our above-mentioned company-wide initiatives; and (iii) lower non-cash compensation expense attributable to our LTIP. Our year-over-year comparisons for the three and nine months ended September 30, 2012 were also affected by the benefits realized as a result of our July 2012 restructuring activities.

Renewable Energy Operations

Our current operations produce renewable energy through the waste-to-energy facilities that are managed by our Wheelabrator Group and our landfill gas-to-energy operations. We are actively seeking opportunities to enhance our existing renewable energy service offerings so that we can respond to the shifting demands of consumers and act as a leader in environmental stewardship.

We are disclosing the following supplemental information related to the operating results of our renewable energy operations for the three and nine months ended September 30, 2012 and 2011 (in millions) because we believe that it provides information about the significance of our current renewable energy operations, the profitability of these operations, and the costs we are incurring to develop these operations.

(a) Our landfill gas-to-energy business focuses on generating a renewable energy source from the methane that is produced as waste decomposes. The operating results include the revenues and expenses of landfill gas-to-energy plants that we own and operate, as well as revenues generated from the sale of landfill gas to third-party owner/operators. The operating results of our landfill gas-to-energy business are included within our geographic reportable segments and “Other.”

(b) Includes businesses and entities we have acquired or invested in through our Organic Growth Group’s business development efforts. These businesses include a landfill gas-to-LNG facility; landfill gas-to-diesel fuels technologies; organic waste streams-to-fuels technologies; and other engineered fuels technologies. The operating results of our Growth Opportunities are included within “Other” in our assessment of our income from operations by segment.

Interest Expense

Our interest expense was $123 million during the three months ended September 30, 2012, an increase of $5 million, or 4.2% from the comparable prior year period. For the nine months ended September 30, 2012, interest expense was $366 million compared with $358 million during the nine months ended September 30, 2011, an increase of $8 million, or 2.2%. The year-over-year increases in interest expense are attributable to higher debt balances. Our average debt balances for both the three- and nine-month periods ended September 30, 2012 are over 6% higher than our average debt balances in the prior year periods due to our use of debt to fund spending on acquisitions and investments.

56

The increase in interest expense is less significant than the increase in our debt balances due to interest expense reductions resulting from (i) a decrease in our weighted average borrowing rate that has been achieved by issuing new debt at much lower fixed interest rates than debt repaid upon scheduled maturities; and (ii) a decrease in the costs attributable to our revolving credit facility, which was refinanced in May 2011.

Equity in Net Losses of Unconsolidated Entities

Our “Equity in net losses of unconsolidated entities” is primarily related to our noncontrolling interests in two limited liability companies established to invest in and manage low-income housing properties and a refined coal facility, as well as (i) noncontrolling investments made to support our strategic initiatives and (ii) unconsolidated trusts for final capping, closure, post-closure or environmental obligations. The tax impacts realized as a result of our investments in low-income housing properties and the refined coal facility are discussed below inProvision for Income Taxes.Refer to Notes 5 and 13 to the Condensed Consolidated Financial Statements for more information related to these investments.

During the third quarter of 2012, we recognized a charge of $10 million related to a payment we made under a guarantee on behalf of an unconsolidated entity accounted for under the equity method.

Other, net

During the third quarter of 2012, we recognized an impairment charge of $14 million relating to an other-than-temporary decline in the value of an investment accounted for under the cost method. We wrote down the carrying value of our investment to its fair value based on other third-party investors’ recent transactions in these securities, which are considered to be the best evidence of fair value currently available.

Provision for Income Taxes

We recorded a provision for income taxes of $125 million during the third quarter of 2012, representing an effective income tax rate of 36.1%, compared with a provision for income taxes of $136 million during the third quarter of 2011, representing an effective income tax rate of 32.3%. Our effective income tax rate for the nine months ended September 30, 2012 was 34.5% compared with 34.0% for the nine months ended September 30, 2011. The increase in our provision for income taxes when comparing the three months ended September 30, 2012 with the prior year is due primarily to the unfavorable impact of adjustments to our accruals and related deferred taxes due to the filing of our 2011 income tax returns and the tax implications of impairments of unconsolidated investments.

Our investments in low-income housing properties and the refined coal facility reduced our provision for income taxes by $11 million and $6 million, respectively, for the three months ended September 30, 2012 and by $27 million and $14 million, respectively, for the nine months ended September 30, 2012. These investments reduced our provision for income taxes by $9 million and $4 million, respectively, for the three months ended September 30, 2011 and by $27 million and $11 million, respectively, for the nine months ended September 30, 2011. Refer to Note 5 to the Condensed Consolidated Financial Statements for more information related to these investments.

On July 28, 2011, we acquired Oakleaf and its primary operations. As a result of the acquisition, we received income tax attributes (primarily federal and state net operating losses) and allocated a portion of the purchase price to these acquired assets. At the time of the acquisition, we fully recognized all of the tax attributes identified by the seller and concluded the realization of these attributes would not affect our overall provision for income taxes. In the third quarter of 2012, as a result of new information, we recognized a tax benefit of approximately $8 million related to additional Oakleaf federal net operating losses received in the acquisition. At this time we do not anticipate the remaining tax attributes, when realized, to affect our overall provision for income taxes. While these tax attributes are not expected to affect our provision for income taxes, they will have a favorable impact on our cash taxes, although we do not anticipate the impact to be material to our overall cash flow from operations.

57

Noncontrolling Interests

Net income attributable to noncontrolling interests was $9 million and $32 million for the three and nine months ended September 30, 2012 and $13 million and $36 million for the three and nine months ended September 30, 2011, respectively. These amounts are principally related to third parties’ equity interests in two limited liability companies that own three waste-to-energy facilities operated by our Wheelabrator Group. Refer to Note 13 to the Condensed Consolidated Financial Statements for information related to the consolidation of these variable interest entities.

As of September 30, 2012, we had $708 million of debt maturing within the next twelve months, including U.S. $117 million of advances outstanding under our Canadian credit facility, $400 million of 6.375% senior notes that mature in November 2012 and $141 million of tax-exempt bonds. We also had $663 million of tax-exempt borrowings subject to repricing within the next twelve months. We have classified $545 million of these tax-exempt borrowings as long-term based on our intent and ability to fund any failed remarketings with available capacity under our revolving credit facility.

Summary of Cash Flow Activity

The following is a summary of our cash flows for the nine-month periods ended September 30 (in millions):

	Nine Months Ended September 30,

Net Cash Provided by Operating Activities — We generated $1,718 million of cash flows from operating activities during the nine-month period ended September 30, 2012 compared with $1,737 million during the nine-month period ended September 30, 2011. The $19 million decrease was primarily driven by the following:

Ÿ Decrease in earnings — Our income from operations, excluding depreciation and amortization, decreased by $73 million on a year-over-year basis. Included in the $73 million decrease are the following offsetting charges and expense reversals that, when combined, had very little impact on the overall decrease in our net cash provided by operating activities:

Ÿ Higher non-cash charges in 2012 related to impairments and restructuring costs of $49 million and $36 million, respectively;

Ÿ Lower non-cash charges attributable to equity-based compensation expense and interest accretion of $17 million and $19 million, respectively; and

Ÿ Lower year-to-date bonus expense in 2012 when compared with 2011.

Ÿ Forward-starting swaps — During the first quarter of 2011 and the third quarter of 2012, forward-starting interest rate swaps associated with anticipated fixed-rate debt issuances were terminated contemporaneously with the issuance of senior notes and we paid cash of $9 million and $59 million, respectively, to settle the liabilities related to these swap agreements. These cash payments have been classified as a change in “Other liabilities” within “Net cash provided by operating activities” in the Condensed Consolidated Statement of Cash Flows; and

Ÿ Changes in assets and liabilities, net of effects from business acquisitions and divestitures — Our cash flow from operations was unfavorably impacted in 2012 by changes in our working capital accounts. Although our working capital changes may vary from year to year, they are typically driven by changes in accounts receivable, which are affected by both revenue changes and timing of payments received, and accounts payable changes, which are affected by both cost changes and timing of payments; partially offset by,

Ÿ Decreased income tax payments — Cash paid for income taxes, net of excess tax benefits associated with equity-based transactions, was approximately $70 million lower on a year-over-year basis; however, we currently expect our full year cash tax payments to increase on a year-over-year basis as a result of the decrease in the bonus depreciation allowance from a deduction of 100% of qualifying capital expenditures for property placed in service in 2011 to a deduction of 50% of qualifying capital expenditures for property placed in service in 2012. SeeLiquidity Impacts of Income Tax Itemsbelow for additional information; and

Ÿ Termination of interest rate swaps — In April 2012, we elected to terminate our $1 billion interest rate swap portfolio associated with senior notes that were scheduled to mature from November 2012 through March 2018. Upon termination of the swaps, we received $72 million in cash for their fair value. The cash proceeds received from the termination of interest rate swap agreements have been classified as a change in “Other assets” within “Net cash provided by operating activities” in the Condensed Consolidated Statement of Cash Flows.

Net Cash Used in Investing Activities — The most significant items included in our investing cash flows for the nine-month periods ended September 30, 2012 and 2011 are summarized below:

Ÿ Capital expenditures — We used $1,132 million during the first nine months of 2012 for capital expenditures compared with $909 million in the first nine months of 2011, an increase of $223 million. The increase in capital expenditures in 2012 is a result of our increased spending on compressed natural gas vehicles, related fueling infrastructure and growth initiatives. The comparison was also affected by timing differences associated with cash payments for the previous years’ fourth quarter capital spending. Approximately $244 million of our fourth quarter 2011 spending was paid in cash in the first quarter of 2012 compared with approximately $206 million of our fourth quarter 2010 spending that was paid in the first quarter of 2011.

Ÿ Acquisitions — Our spending on acquisitions was $178 million in the first nine months of 2012 compared with $645 million in the first nine months of 2011. In 2012, our acquisitions consisted primarily of

59

interests in oil and gas producing properties through two transactions, for which we paid $94 million. The remainder of our 2012 acquisitions related to collection and recycling operations. In 2011, we paid $432 million, net of cash received of $4 million and inclusive of certain other adjustments, to acquire Oakleaf, which continues to provide outsourced waste and recycling services.

Ÿ Investments in unconsolidated entities — We made $61 million and $92 million of cash investments in unconsolidated entities during the first nine months of 2012 and 2011, respectively. The investments in 2012 were related to furthering our goal of growing into new markets, while the investments made in 2011 were primarily related to a $48 million payment made to acquire a noncontrolling interest in a limited liability company that generates refined coal tax credits and $43 million of investments in greener technologies related to our growth initiatives.

Ÿ Other — Net cash used by our other investing activities of $33 million during the first nine months of 2012 was primarily associated with the funding of notes receivable associated with our Wheelabrator Group’s investments in Europe. Net cash provided by our other investing activities of $15 million during the first nine months of 2011 was primarily related to the receipt of a payment of $17 million associated with a note receivable from a prior year divestiture.

Net Cash Used in Financing Activities — During the nine months ended September 30, 2012, net cash used in financing activities was $219 million compared with $459 million during the comparable prior year period. The most significant items affecting the comparison of our financing cash flows for the nine-month periods ended September 30, 2012 and 2011 are summarized below:

Ÿ Debt borrowings and repayments — The following summarizes our cash borrowings and debt repayments during each period (in millions):

	Nine Months Ended September 30,
	2012			2011
Borrowings:
Revolving credit facility	$	—		$	100

	$	(473	)	$	(425	)
Net borrowings	$	212		$	576

Refer to Note 3 to the Condensed Consolidated Financial Statements for additional information related to our debt borrowings and repayments.

Ÿ Dividend payments and share repurchases — We paid $493 million in cash dividends in the first nine months of 2012 compared with $481 million in the first nine months of 2011. The increase in dividend payments is due to our quarterly per share dividends increasing from $0.34 in 2011 to $0.355 in 2012, partially offset by a reduction in the number of outstanding shares as a result of our share repurchase program in 2011.

60

We repurchased 16.4 million shares of our common stock for $546 million during the first nine months of 2011, of which approximately $18 million was paid in October 2011. There were no share repurchases during the first nine months of 2012.

Ÿ Other — Net cash provided by our other financing activities was $44 million during the first nine months of 2012 compared with net cash used of $43 million during the first nine months of 2011 (including $7 million of financing costs paid to amend and restate our $2.0 billion revolving credit facility). The remaining use of cash in 2011 and the source of cash in 2012 were driven by changes in our accrued liabilities for checks written in excess of related cash balances due to the timing of cash deposits or payments.

Liquidity Impacts of Income Tax Items

Recent Legislation — The Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act, signed into law on December 17, 2010, included an extension of the bonus depreciation allowance through the end of 2012 and increased the amount of qualifying capital expenditures that can be depreciated immediately from 50% to 100%. The 100% depreciation deduction applied to qualifying property placed in service from September 8, 2010 through December 31, 2011. The depreciation deduction for qualifying property placed in service in 2012 has been reduced to 50%. The acceleration of deductions on capital expenditures resulting from the bonus depreciation provisions has no impact on our effective tax rate, but reduces our cash taxes in the periods in which the deductions are taken.

The acceleration of depreciation deductions related to qualifying property additions in 2011 decreased our full year 2011 cash taxes by approximately $190 million and, based on our current forecast of 2012 capital expenditures, we estimate a reduction in our full year 2012 cash taxes of approximately $90 million related to qualifying property additions in 2012. However, taking accelerated deductions results in increased cash taxes in subsequent periods when the deductions for these capital expenditures would have otherwise been taken. On a net basis, after taking into account the effect of all applicable years’ bonus depreciation programs, our full year 2011 cash taxes benefitted by approximately $139 million and the deductions taken in previous years from acceleration programs will more than offset the $90 million benefit expected to be received from accelerated depreciation deductions in 2012.

In addition, as a result of the application of the depreciation safe harbor provisions of the Income Tax Regulations, our estimated income tax payments during the first nine months of 2012 were lower than the estimated income tax payments made during the first nine months of 2011. However, we currently expect our full year tax payments to be approximately $100 million higher than the full year tax payments made in 2011.

Uncertain Tax Positions — We have liabilities associated with unrecognized tax benefits and related interest. These liabilities are primarily included as a component of long-term “Other liabilities” in our Condensed Consolidated Balance Sheet because the Company generally does not anticipate that settlement of the liabilities will require payment of cash within the next twelve months. We are not able to reasonably estimate when we would make any cash payments required to settle these liabilities, but do not believe that the ultimate settlement of our obligations will materially affect our liquidity. We anticipate that approximately $8 million of liabilities for uncertain tax positions, including accrued interest, and $3 million of related deferred tax assets may be reversed within the next twelve months. The anticipated reversals are related to state tax items, none of which are material, and are expected to result from audit settlements or the expiration of the applicable statute of limitations period.

Off-Balance Sheet Arrangements

We have financial interests in unconsolidated variable interest entities as discussed in Note 13 to the Condensed Consolidated Financial Statements. Additionally, we are party to guarantee arrangements with unconsolidated entities as discussed in theGuaranteessection of Note 7 to the Condensed Consolidated Financial Statements. These arrangements have not materially affected our financial position, results of operations or liquidity during the nine months ended September 30, 2012, nor are they expected to have a material impact on our future financial position, results of operations or liquidity.

61

Seasonal Trends

Our operating revenues normally tend to be somewhat higher in the summer months, primarily due to the traditional seasonal increase in the volume of construction and demolition waste. Historically, the volumes of industrial and residential waste in certain regions in which we operate have tended 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 the hurricanes that most often impact our Southern Group, can actually increase our revenues in the areas affected. While weather-related and other “one-time” occurrences can boost revenues through additional work, as a result of significant start-up costs and other factors, such revenue sometimes 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.

Inflation

While inflationary increases in costs, including the cost of diesel fuel, have affected our operating margins in recent years, we believe that inflation generally has not had, and in the near future is not expected to have, any material adverse effect on our results of operations. However, a portion of our collection revenues are generated under long-term agreements with price adjustments based on various indices intended to measure inflation. Additionally, management’s estimates associated with inflation have had, and will continue to have, an impact on our accounting for landfill and environmental remediation liabilities.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Information about market risks as of September 30, 2012, does not differ materially from that discussed under Item 7A in our Annual Report on Form 10-K for the year ended December 31, 2011.

Item 4. Controls and Procedures.

Effectiveness of Controls and Procedures

Our management, with the participation of our principal executive and financial officers, has evaluated the effectiveness of our disclosure controls and procedures in ensuring that the information required to be disclosed in reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including ensuring that such information is accumulated and communicated to management (including the principal executive and financial officers) as appropriate to allow timely decisions regarding required disclosure. Based on such evaluation, our principal executive and financial officers have concluded that such disclosure controls and procedures were effective as of September 30, 2012 (the end of the period covered by this Quarterly Report on Form 10-Q).

Changes in Internal Controls over Financial Reporting

Management, together with our principal executive and financial officers, evaluated the changes in our internal control over financial reporting during the quarter ended September 30, 2012. We determined that there were no changes in our internal control over financial reporting during the quarter ended September 30, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
