Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Basis of Presentation | 1. Basis of Presentation The financial statements presented in this report represent the consolidation of Waste Management, Inc., a Delaware corporation; Waste Management’s wholly-owned and majority-owned subsidiaries; and certain variable interest entities for which Waste Management or its subsidiaries are the primary beneficiary as described in Note 14. 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. We are North America’s leading provider of comprehensive waste management environmental services. We partner with our residential, commercial, industrial and municipal customers and the communities we serve to manage and reduce waste at each stage from collection to disposal, while recovering valuable resources and creating clean, renewable energy. Our “Solid Waste” business is operated and managed locally by our subsidiaries that focus on distinct geographic areas and provides collection, transfer, recycling and resource recovery, and disposal services. Through our subsidiaries, we are also a leading developer, operator and owner of waste-to-energy and landfill gas-to-energy facilities in the United States. Through the third quarter of 2012, the operations of our local subsidiaries were primarily organized under our Eastern, Midwest, Southern, Western and Wheelabrator operating Groups. 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. Principal organizational changes included removing the management layer of our four geographic Groups, each of which previously constituted a reportable segment, and consolidating and reducing the number of geographic Areas from 22 to 17. Following our reorganization, our senior management now evaluates, oversees and manages the financial performance of our Solid Waste business subsidiaries through these 17 Areas. Our reportable segments have been realigned to conform with our new organizational structure. Our Wheelabrator business 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 Solid Waste or Wheelabrator businesses, including our strategic accounts program that expanded with the acquisition of Oakleaf Global Holdings on July 28, 2011 (“Oakleaf”), which are presented in this report as “Other.” Additional information related to our segments can be found in Note 8. The Condensed Consolidated Financial Statements as of June 30, 2013 and for the three and six months ended June 30, 2013 and 2012 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, comprehensive income, cash flows, and changes in equity 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, 2012. 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.
Adoption of New Accounting Pronouncement Comprehensive Income — In February 2013, the Financial Accounting Standards Board issued amended authoritative guidance associated with comprehensive income, which requires companies to provide information about the amounts that are reclassified out of accumulated other comprehensive income by component. Additionally, companies are required to present significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amendment to authoritative guidance associated with comprehensive income was effective for the Company on January 1, 2013. The adoption of this guidance did not have a material impact on our consolidated financial statements. We have presented the information required by this amendment in Note 12. Reclassifications Certain reclassifications have been made to our prior period consolidated financial information in order to conform to the current year presentation. |

Debt | 3. Debt The following table summarizes the major components of debt at each balance sheet date (in millions) and provides the maturities and interest rate ranges of each major category as of June 30, 2013:
Debt Classification As of June 30, 2013, we had (i) $902 million of debt maturing within the next 12 months, including $335 million of borrowings outstanding under the revolving credit facility, U.S.$24 million of advances outstanding under our Canadian credit facility, $350 million of 5.0% senior notes that mature in March 2014 and $110 million of tax-exempt bonds and (ii) $577 million of tax-exempt borrowings subject to repricing within the next 12 months. Based on our intent and ability to refinance a portion of this debt on a long-term basis as of June 30, 2013, we have classified $703 million of this debt as long-term and the remaining $776 million as current obligations. Revolving Credit and Letter of Credit Facilities As of June 30, 2013, we had an aggregate committed capacity of $2.4 billion for letters of credit under various credit facilities. Our $2.0 billion revolving credit facility is our primary source of letter of credit capacity. As of June 30, 2013, we had an aggregate of $1.4 billion of letters of credit outstanding under various credit facilities. Approximately $961 million of these letters of credit have been issued under our revolving credit facility. We had $335 million of outstanding borrowings under our revolving credit facility as of June 30, 2013, leaving $704 million of unused and available capacity. In July 2013, we amended and restated our $2.0 billion revolving credit facility, increasing our total credit capacity to $2.25 billion and extending the term through July 2018. Significant Changes in Debt Balances Net Debt Repayments — We had net debt repayments of $197 million during the six months ended June 30, 2013, largely attributable to (i) $65 million of net repayments under our revolving credit facility; (ii) U.S.$50 million of repayments of net advances under our Canadian credit facility; and (iii) the repayment of $67 million of tax-exempt bonds.
Other — We had increases in our other obligations during the six months ended June 30, 2013, primarily related to the deferred purchase price of (i) land needed to support a landfill expansion and (ii) Greenstar, LLC, which is discussed further in Note 9. |

Derivative Instruments and Hedging Activities | 4. Derivative Instruments and Hedging Activities The following table summarizes the fair values of derivative instruments recorded in our Condensed Consolidated Balance Sheet (in millions):
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 13. Fair Value Hedges Interest Rate Swaps In prior years, we used interest rate swaps to maintain a portion of our debt obligations at variable market interest rates. As of June 30, 2013 and December 31, 2012, we did not have any of these swaps outstanding. In April 2012, we elected to terminate our interest rate swaps related to the interest payments on $1 billion of our senior notes 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 with maturities between November 2012 and 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. 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 $69 million as of June 30, 2013 and $79 million as of December 31, 2012, representing the unamortized portion of our terminated swaps. We recognize the impacts of (i) net periodic settlements of current interest on our active interest rate swaps, if any, and (ii) the amortization of previously terminated interest rate swap agreements as adjustments to interest expense. The following table summarizes the impact of periodic settlements of active swap agreements and the impact of terminated swap agreements on our results of operations (in millions):
Cash Flow Hedges Forward-Starting Interest Rate Swaps In prior years, 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 third quarter of 2012, $200 million of these forward-starting interest rate swaps were terminated contemporaneously with the actual issuance of senior notes in September 2012, and we paid cash of $59 million to settle the liabilities related to these swap agreements. The ineffectiveness recognized upon termination of these hedges was immaterial. At June 30, 2013 and December 31, 2012, our “Accumulated other comprehensive income” included $36 million and $39 million, respectively, of after-tax deferred losses related to all previously terminated swaps, which 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. As of June 30, 2013, $7 million (on a pre-tax basis) is scheduled to be reclassified as an increase to interest expense over the next 12 months. The active forward-starting interest rate swaps outstanding as of June 30, 2013 relate to an anticipated debt issuance to repay the $350 million of 5.0% senior notes that mature in March 2014. As of June 30, 2013, the fair value of these active interest rate derivatives was comprised of $30 million of current liabilities compared with $42 million of long-term liabilities as of December 31, 2012. Treasury Rate Locks As of both June 30, 2013 and December 31, 2012, our “Accumulated other comprehensive income” included $7 million of after-tax deferred losses associated with Treasury rate locks that had been executed in previous years in anticipation of senior note issuances. These deferred losses are reclassified as an increase to interest expense over the life of the related senior note issuances, which extend through 2032. As of June 30, 2013, $2 million (on a pre-tax basis) is scheduled to be reclassified as an increase to interest expense over the next 12 months. 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 WM Holdings and one of its Canadian subsidiaries. As of June 30, 2013, 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 June 30, 2013 include C$370 million of principal and C$10 million of interest which are scheduled to be repaid on October 31, 2013. We designated these 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. Electricity Commodity Derivatives We use “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 628,800 megawatt hours, or approximately 20%, of Wheelabrator’s full year 2012 merchant electricity sales and the swaps executed through June 30, 2013 are expected to hedge about 1.75 million megawatt hours, or approximately 55%, of Wheelabrator’s full year 2013 merchant electricity sales. For the three-month periods ended June 30, 2013 and 2012, we hedged 56% and 16%, respectively, of our merchant electricity sales. For the six-month periods ended June 30, 2013 and 2012, we hedged 54% and 24%, respectively, of our merchant electricity sales. Amounts reported in other comprehensive income and accumulated other comprehensive income are reported net of tax. The following table summarizes the pre-tax impacts of our cash flow derivatives on our comprehensive income and results of operations (in millions):
There was no significant ineffectiveness associated with our cash flow hedges during the three and six months ended June 30, 2013 or 2012. 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 June 30, 2013 and December 31, 2012, we did not have any interest rate derivatives outstanding that contained these credit-risk-related features. |

Income Tax Disclosure [Abstract] | |||
Income Taxes |
Our effective income tax rate for the three and six months ended June 30, 2013 was 33.2% and 33.0%, respectively, compared with 34.3% and 33.6%, respectively, for the comparable prior year periods. We evaluate our effective income tax rate at each interim period and adjust it as facts and circumstances warrant. The differences between federal income taxes computed at the federal statutory rate and reported income taxes for the reported periods were primarily due to the favorable impact of federal and state tax credits and tax audit settlements 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. 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 Statements of Operations. During the three and six months ended June 30, 2013, we recognized $2 million and $3 million of net losses resulting from our share of the entity’s operating losses and $1 million and $2 million during the three and six months ended June 30, 2012. Our tax provision for the three and six months ended June 30, 2013 was reduced by $6 million and $9 million, respectively, primarily as a result of tax credits realized from this investment and by $5 million and $8 million for the three and six months ended June 30, 2012, respectively. See Note 14 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 Statements of Operations. The value of our investment decreases as the tax credits are generated and utilized. During the three and six months ended June 30, 2013, we recognized $6 million and $12 million of losses relating to our equity investment in this entity, $2 million and $3 million of interest expense, and a reduction in our tax provision of $10 million (including $7 million of tax credits) and $17 million (including $11 million of tax credits), respectively. During the three and six months ended June 30, 2012, we recognized $6 million and $12 million of losses relating to our equity investment in this entity, $2 million and $3 million of interest expense, and a reduction in our tax provision of $9 million (including $6 million of tax credits) and $16 million (including $10 million of tax credits), respectively. See Note 14 for additional information related to this investment. Recent Legislation — The American Taxpayer Relief Act of 2012 was signed into law on January 2, 2013 and includes an extension for one year of the bonus depreciation allowance. As a result, 50% of qualifying capital expenditures on property placed in service before January 1, 2014 can be depreciated immediately. The acceleration of deductions on 2013 qualifying capital expenditures resulting from the bonus depreciation provision will have no impact on our 2013 effective tax rate although it will reduce our cash taxes. |

Commitments And Contingencies Disclosure [Abstract] | |||
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. 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 for both consolidated and unconsolidated entities. Guarantee agreements outstanding as of June 30, 2013 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 or other market conditions 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. We do not currently believe that contingent obligations to provide indemnification or pay additional post-closing consideration in connection with our divestitures or acquisitions will have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.
Environmental Matters — A significant portion of our operating costs and capital expenditures could be characterized as costs of environmental protection as we are subject to an array of laws and regulations relating to the protection of the environment. Under current laws and regulations, we may have liabilities for environmental damage caused by our operations, or for damage caused by conditions that existed before we acquired a site. In addition to remediation activity required by state or local authorities, such liabilities include potentially responsible party, or PRP, investigations. The costs associated with these liabilities can include settlements, certain legal and consultant fees, as well as incremental internal and external costs directly associated with site investigation and clean-up. Estimating our degree of responsibility for remediation is inherently difficult. 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 $145 million higher than the $239 million recorded in the Condensed Consolidated Financial Statements as of June 30, 2013. 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 June 30, 2013, we had been notified by the government 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, 15 are sites we own. Each of the NPL sites we own was initially developed by others as a landfill disposal facility. At each of these facilities, we are working in conjunction with the government to evaluate 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 65 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 matter is disclosed in accordance with that requirement. We do not currently believe that the eventual outcome of such matter could have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows. 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. Additionally, the United States Attorney’s Office for the District of Hawaii has been conducting 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 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 execute an undertaking to 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 of Directors, its Chief Executive Officer and each of its executive vice presidents. The employment agreements between WM and its Chief Executive Officer and other executive and senior vice presidents also 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, and we have recognized charges to “Operating” expense associated with the withdrawal of certain bargaining units from the Central States Pension Plan and other underfunded multiemployer pension plans. 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 certain previous withdrawals. Except in the case of our withdrawals from the Central States Pension Plan, 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, liquidity, results of operations or cash flows. In addition to charges recognized in prior years, we currently estimate that we could incur up to approximately $40 million in future charges based on demands from representatives of the Central States Pension Plan. As a result, we do not anticipate that the final resolution of the Central States Pension Plan matter could be material to the Company’s business, financial condition or liquidity; however, such loss could have a material adverse effect on our cash flows and, to a lesser extent, our results of operations, for a particular reporting period. Similarly, we also do not believe that any future withdrawals, individually or in the aggregate, from the multiemployer pension 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 or cash flows for a particular reporting period, depending on the number of employees withdrawn in any future period and the financial condition of the multiemployer pension 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 2012 and 2013 and expect these audits to be completed within the next nine and 21 months, respectively. We participate in the IRS’s Compliance Assurance Process, which means we work with the IRS throughout the year in order to resolve any material issues prior to the filing of our annual tax return. We are also currently undergoing audits by various state and local jurisdictions that date back to 2000. We are not currently under audit in Canada and, due to the expiration of statutes of limitations, all tax years prior to 2008 are closed. Oakleaf is subject to potential IRS examinations for years dating back to 2009. Pursuant to the terms of our acquisition of Oakleaf, we are entitled to indemnification for Oakleaf’s pre-acquisition period 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. |

Segment and Related Information |
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 included removing the management layer of our four geographic Groups, each of which previously constituted a reportable segment, and consolidating and reducing the number of our geographic Areas from 22 to 17. Following our reorganization, our senior management now evaluates, oversees and manages the financial performance of our Solid Waste subsidiaries through these 17 Areas. The 17 Areas constitute our operating segments and none of the Areas individually meet the quantitative criteria to be a separate reportable segment. We considered the similarities between our Areas, including the fact that our Solid Waste business is homogenous across geography with the same services offered across the Areas, and we concluded that aggregation of our Areas is appropriate for purposes of presenting our reportable segments. Accordingly, we have aggregated our 17 Areas into three tiers that we believe have similar economic characteristics and future prospects based in large part on a review of the Areas’ operating margins. The economic variations experienced by our Areas is attributable to a variety of factors, including regulatory environment of the Area; economic environment of the Area, including level of commercial and industrial activity; population density; service offering mix and disposal logistics, with no one factor being singularly determinative of an Area’s current or future economic performance. As a result of our consideration of economic and other similarities, we have established the following three reportable segments for our Solid Waste business: Tier 1, which is comprised almost exclusively of Areas in the Southern United States; Tier 2, which is comprised predominately of Areas located in the Midwest and Northeast United States; and Tier 3, which encompasses all Areas not included in Tier 1 or Tier 2. Our Wheelabrator business, which manages waste-to-energy facilities and independent power production plants, continues to be a separate reportable segment as it meets one of the quantitative disclosure thresholds. The operating segments not evaluated and overseen through the 17 Areas and Wheelabrator are presented herein as “Other” as these operating segments do not meet the criteria to be aggregated with other operating segments and do not meet the quantitative criteria to be separately reported.
Summarized financial information concerning our reportable segments for the three and six months ended June 30 is shown in the following table (in millions):
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, changes in commodity prices and by general economic conditions. In addition, our revenues and income from operations typically reflect seasonal patterns. Our operating revenues tend to be somewhat higher in the summer months, primarily due to the higher volume of construction and demolition waste. The volumes of industrial and residential waste in certain regions where we operate also tend to increase during the summer months. Our second and third quarter revenues and results of operations typically reflect these seasonal trends. Additionally, certain destructive weather conditions that tend to occur during the second half of the year, such as the hurricanes that most often impact our operations in the Southern and Eastern U.S., can actually increase our revenues in the areas affected. While weather-related and other “one-time” occurrences can boost revenues through additional work for a limited time span, 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. |

Business Combinations [Abstract] | |
Acquisitions | 9. Acquisitions Greenstar, LLC — On January 31, 2013, we paid $170 million inclusive of certain adjustments, to acquire Greenstar, LLC (“Greenstar”). Pursuant to the sale and purchase agreement, up to an additional $40 million is payable to the sellers during the period from 2014 to 2018; a portion of this consideration is contingent based on changes in certain recyclable commodity indexes. This additional consideration had a preliminary estimated fair value at closing of $36 million. Greenstar is an operator of recycling and resource recovery facilities. This acquisition will provide the Company’s customers with greater access to recycling solutions by supplementing the Company’s extensive nationwide recycling network with the operations of one of the nation’s largest private recyclers. For the three and six months ended June 30, 2013, Greenstar recognized revenues of $40 million and $65 million, respectively, and net losses of $4 million and $7 million, respectively, which are included in our Condensed Consolidated Statements of Operations. The preliminary allocation of purchase price was primarily to “Other intangible assets,” consisting primarily of supplier relationships, which had an estimated fair value of $32 million; “Property and equipment,” which had an estimated fair value of $57 million; and “Goodwill” of $122 million. Goodwill is the result of synergies expected to be achieved from combining the operations of Greenstar with those of the Company. Goodwill has been assigned predominantly to our Areas and, to a lesser extent, our recycling brokerage services, as they are expected to benefit from the synergies of the combination. Goodwill related to this acquisition is deductible for income tax purposes. Adjustments to the preliminary allocation of the purchase price of Greenstar were immaterial for the three and six months ended June 30, 2013. Other — During the first half of 2013, we also paid approximately $40 million primarily to acquire seven businesses related to our collection and energy services operations. During the first half of 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, we acquired eight other businesses related to our collection and recycling operations in the first half of 2012. |

Restructuring And Related Activities [Abstract] | |
Restructuring | 10. Restructuring During the first half of 2013, we recognized a total of $10 million of pre-tax restructuring charges, of which $3 million was related to employee severance and benefit costs, including costs associated with our acquisition of Greenstar and our 2012 restructuring. The remaining charges were primarily related to operating lease obligations for property that will no longer be utilized.
During the first half of 2012, we recognized a total of $7 million of employee severance and benefit restructuring charges, including $3 million associated with the reorganization of Oakleaf and certain other actions taken by the Company. Through June 30, 2013, we had recognized charges of $77 million related to employee severance and benefits associated with our restructuring efforts beginning in 2011 and we have paid approximately $65 million of these costs. At June 30, 2013, we had approximately $9 million of accrued employee severance related to our restructuring efforts, which will be paid through the end of 2014. |

Extraordinary And Unusual Items [Abstract] | |
Asset Impairments and Unusual Items | 11. Asset Impairments and Unusual Items (Income) expense from divestitures, asset impairments and unusual items During the first half of 2013, we recognized net charges of $15 million, primarily related to a $14 million impairment charge at a waste-to-energy facility as a result of projected operating losses. We wrote down the carrying value of the facility’s property, plant and equipment to its estimated fair value. Also included are (i) $6 million of losses on divestitures related to investments in oil and gas producing properties and (ii) $4 million of charges primarily to impair goodwill related to certain of our operations, which are included in our “Other” operations in Note 8. These charges were offset, in part, by gains on divestures of $9 million, largely attributable to the sale of a transfer station in our Greater Mid-Atlantic Area. During the first half 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. Other income (expense) During the first quarter of 2013, we recognized impairment charges of $11 million relating to other-than-temporary declines in the value of two investments in waste diversion technologies accounted for under the cost method. Partially offsetting these charges was a $4 million gain on the sale of a similar investment recognized in the second quarter of 2013. These net charges are recorded in “Other, net” in our Condensed Consolidated Statement of Operations. |

Fair Value Measurements |
Assets and Liabilities Accounted for at Fair Value Our assets and liabilities that are measured at fair value on a recurring basis include the following (in millions):
Fair Value of Debt At June 30, 2013 and December 31, 2012, the carrying value of our debt was approximately $9.8 billion and $9.9 billion, respectively. 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 $10.5 billion at June 30, 2013 and approximately $11.3 billion at December 31, 2012. 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 decrease in the fair value of our debt when comparing June 30, 2013 with December 31, 2012 is primarily related to recent increases in long-term interest rates, which have caused a decline in market prices for fixed-rate corporate debt securities. 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 June 30, 2013 and December 31, 2012. These amounts have not been revalued since those dates, and current estimates of fair value could differ significantly from the amounts presented. |

Accounting Policies [Abstract] | |||
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 equity ownership percentages until Hancock and CIT achieve targeted returns on their initial capital investments in each respective LLC. All allocations made through June 30, 2013 have been based on initial equity ownership percentages as the target returns have not yet been achieved for either LLC. We currently expect Hancock and CIT to achieve their targeted return on LLC II in late 2013 and Hancock to receive its targeted return on LLC I in late 2014. After the investors have achieved their targeted returns, the LLC agreements provide that we will receive 80% of the earnings of each of the LLCs and Hancock and CIT will be allocated the remaining 20%. 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 June 30, 2013 and December 31, 2012, our Condensed Consolidated Balance Sheets included $290 million and $296 million, respectively, of net property and equipment associated with the LLCs’ waste-to-energy facilities and $244 million and $245 million, respectively, in noncontrolling interests associated with Hancock’s and CIT’s interests in the LLCs. We recognized reductions in consolidated earnings of $11 million and $22 million for the three and six months ended June 30, 2013, respectively, and $12 million and $25 million for the three and six months ended June 30, 2012, respectively, for Hancock’s and CIT’s noncontrolling interests in the LLCs’ earnings, which are included in our consolidated net income. 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 Recycling Entity — In the first quarter of 2012, we formed a U.K. joint venture (the “JV”), together with a commercial waste management company (“Partner”), to develop, construct, operate and maintain a waste-to-energy and recycling facility in England. We own a 50% interest in the JV. The total cost of constructing this facility is expected to be £200 million, or $304 million based on the exchange rate as of June 30, 2013. The JV will be funded primarily through loans from the joint venture partners and loans under the JV’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 $87 million based on the exchange rate as of June 30, 2013, of funding to the JV. Our actual commitment may be more or less depending on the actual cost of the facility. Through June 30, 2013, we had funded approximately £10 million, or $14 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 JV has entered into certain foreign currency and interest rate derivatives at the direction of the governmental authority that awarded the project to the JV. The impacts of gains or losses incurred on these derivatives will ultimately be remitted to or recoverable from the governmental 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 is not material. In addition, a wholly-owned subsidiary of WM will be responsible for constructing the waste-to-energy facility for the JV under a fixed-price construction contract. Once the facility is constructed, a majority-owned subsidiary of WM will be responsible for operating and maintaining the facility for the JV 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 achievable. We also will be jointly responsible, along with our Partner, for the performance of sales and marketing services for the JV through a 50%-owned 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 may not achieve the financial results anticipated and could incur losses if the actual costs differ from the costs established in the contracts. A range of our exposure to potential loss under these contracts cannot presently be estimated. We determined that we are not the primary beneficiary of the JV as all decision-making responsibility is shared jointly with our 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 another 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 June 30, 2013 and December 31, 2012, our investment balance was $25 million and $19 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. Required capital contributions commenced in the first quarter of 2013 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 June 30, 2013 and December 31, 2012, our investment balance was $142 million and $153 million, respectively, and our debt balance was $140 million and $152 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. 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.” These trusts had a fair value of $126 million at June 30, 2013 and $125 million at December 31, 2012. 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 $108 million as of June 30, 2013 and $110 million as of December 31, 2012. 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. |

Subsequent Events [Abstract] | |
Subsequent Event | 16. Subsequent Event On July 5, 2013, we acquired substantially all of the assets of RCI Environnement Inc., the largest waste management company in Quebec, and certain related entities for a price of C$480 million, or $454 million. Total consideration, inclusive of amounts for estimated working capital, paid at closing was C$509 million, or $481 million, and is subject to certain post-closing adjustments. The acquisition was funded primarily with C$500 million, or $473 million, of cash proceeds from a term loan under our 2012 Canadian credit facility. Under the terms and conditions of our 2012 Canadian credit facility, interest on our term loan advances will be based on a 1.4% spread from the applicable Canadian Dealer Offered Rate (CDOR). Our initial CDOR-based advances, which have terms of one month and three months, have a weighted average effective rate of approximately 2.7%. While our outstanding advances have short-term maturities, they may be renewed under the terms of the facility through its maturity. The maturity date of the Canadian credit facility, including the term loan, is November 7, 2017. Waste Management of Canada Corporation and WM Quebec Inc. are the borrowers under the Canadian credit facility, and WM and WM Holdings are guarantors. |

Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
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 14. 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. We are North America’s leading provider of comprehensive waste management environmental services. We partner with our residential, commercial, industrial and municipal customers and the communities we serve to manage and reduce waste at each stage from collection to disposal, while recovering valuable resources and creating clean, renewable energy. Our “Solid Waste” business is operated and managed locally by our subsidiaries that focus on distinct geographic areas and provides collection, transfer, recycling and resource recovery, and disposal services. Through our subsidiaries, we are also a leading developer, operator and owner of waste-to-energy and landfill gas-to-energy facilities in the United States. Through the third quarter of 2012, the operations of our local subsidiaries were primarily organized under our Eastern, Midwest, Southern, Western and Wheelabrator operating Groups. 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. Principal organizational changes included removing the management layer of our four geographic Groups, each of which previously constituted a reportable segment, and consolidating and reducing the number of geographic Areas from 22 to 17. Following our reorganization, our senior management now evaluates, oversees and manages the financial performance of our Solid Waste business subsidiaries through these 17 Areas. Our reportable segments have been realigned to conform with our new organizational structure. Our Wheelabrator business 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 Solid Waste or Wheelabrator businesses, including our strategic accounts program that expanded with the acquisition of Oakleaf Global Holdings on July 28, 2011 (“Oakleaf”), which are presented in this report as “Other.” Additional information related to our segments can be found in Note 8. The Condensed Consolidated Financial Statements as of June 30, 2013 and for the three and six months ended June 30, 2013 and 2012 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, comprehensive income, cash flows, and changes in equity 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, 2012. 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.

Comprehensive Income | Comprehensive Income — In February 2013, the Financial Accounting Standards Board issued amended authoritative guidance associated with comprehensive income, which requires companies to provide information about the amounts that are reclassified out of accumulated other comprehensive income by component. Additionally, companies are required to present significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amendment to authoritative guidance associated with comprehensive income was effective for the Company on January 1, 2013. The adoption of this guidance did not have a material impact on our consolidated financial statements. We have presented the information required by this amendment in Note 12. |

Investment in short-term money-market instruments (such as commercial paper, banker's acceptances, repurchase agreements, government securities, certificates of deposit, and so forth) which are highly liquid (that is, readily convertible to known amounts of cash) and so near their maturity that they present an insignificant risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify as cash equivalents by definition. Original maturity means an original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef
