Basis of Presentation | ​ 1. Basis of Presentation The financial statements presented in this report represent the consolidation of Waste Management, Inc., a Delaware corporation; its wholly-owned and majority-owned subsidiaries; and certain variable interest entities for which Waste Management, Inc. or its subsidiaries are the primary beneficiaries as described in Note 14. Waste Management, Inc. 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 provide collection, transfer, disposal, and recycling and resource recovery services. Through our subsidiaries, we are also a leading developer, operator and owner of landfill gas-to-energy facilities in the United States (“U.S.”). We evaluate, oversee and manage the financial performance of our Solid Waste business subsidiaries through our 17 Areas. We also provide additional services that are not managed through our Solid Waste business, which are presented in this report as “Other.” Additional information related to our segments is included in Note 8. The Condensed Consolidated Financial Statements as of June 30, 2019 and for the three and six months ended June 30, 2019 and 2018 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 conjunction with the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2018. 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 precision from available data or simply cannot be calculated. In some cases, these estimates are 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, long-lived asset impairments 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. Revenue Recognition We generally recognize revenue as services are performed or products are delivered. For example, revenue typically is recognized as waste is collected, tons are received at our landfills or transfer stations, or recycling commodities are collected or delivered as product. We bill for certain services prior to performance. Such services include, among others, certain commercial and residential contracts and equipment rentals. These advance billings are included in deferred revenues and recognized as revenue in the period service is provided. Substantially all our deferred revenues during the reported periods are realized as revenues within one to three months when the related services are performed. Contract Acquisition Costs Our incremental direct costs of obtaining a contract, which consist primarily of sales incentives, are generally deferred and amortized to selling, general and administrative expense over the estimated life of the relevant customer relationship, ranging from 5 to 13 years. Contract acquisition costs that are paid to the customer are deferred and amortized as a reduction in revenue over the contract life. Our contract acquisition costs are classified as current or noncurrent based on the timing of when we expect to recognize amortization and are included in other assets in our Condensed Consolidated Balance Sheet. As of June 30, 2019 and December 31, 2018, we had $149 million and $145 million, respectively, of deferred contract costs, of which $113 million and $109 million, respectively, was related to deferred sales incentives. During the three and six months ended June 30, 2019, we amortized $6 million and $11 million of sales incentives to selling, general and administrative expense, and $5 million and $11 million of other contract acquisition costs as a reduction in revenue, respectively. During the three and six months ended June 30, 2018, we amortized $5 million and $11 million of sales incentives to selling, general and administrative expense, and $9 million and $19 million of other contract acquisition costs as a reduction in revenue, respectively. Adoption of New Accounting Standard Leases — In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02 associated with lease accounting. There were further amendments, including practical expedients, with the issuance of ASU 2018-01 in January 2018, ASU 2018-11 in July 2018 and ASU 2018-20 in December 2018. On January 1, 2019, we adopted these ASUs using the optional transition method which allows entities to continue to apply historical accounting guidance in the comparative periods presented in the year of adoption. Accordingly, our financial statements for the reported periods after January 1, 2019 are presented under this amended guidance, while prior period amounts are not adjusted and continue to be reported in accordance with historical accounting guidance. We elected to apply the following package of practical expedients on a consistent basis permitting entities not to reassess: (i) whether any expired or existing contracts are or contain a lease; (ii) lease classification for any expired or existing leases and (iii) whether initial direct costs for any expired or existing leases qualify for capitalization under the amended guidance. In addition, we applied (i) the practical expedient for land easements, which allows the Company to not apply the lease standard to certain existing land easements at transition and (ii) the practical expedient to include both the lease and non-lease components as a single component and account for it as a lease. The impact of adopting the amended guidance primarily relates to the recognition of lease assets and lease liabilities on the balance sheet for all leases previously classified as operating leases. We recognized $385 million of right-of-use assets and $385 million of related lease liabilities as of January 1, 2019 for our contracts that are classified as operating leases. Leases with an initial term of 12 months, which are not expected to be renewed beyond one year, are not recorded on the balance sheet and are recognized as lease expense on a straight-line basis over the lease term. Our accounting for financing leases, which were formerly referred to as capital leases, remained substantially unchanged. There were no other material impacts on our consolidated financial statements. See Note 4 for additional information and disclosures related to our adoption of this amended guidance. New Accounting Standard Pending Adoption Financial Instrument Credit Losses — In June 2016, the FASB issued ASU 2016-13 associated with the measurement of credit losses on financial instruments. The amended guidance replaces the current incurred loss impairment methodology of recognizing credit losses when a loss is probable, with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to assess credit loss estimates. The amended guidance is effective for the Company on January 1, 2020. We are assessing the provisions of this amended guidance and evaluating the impact on our consolidated financial statements. Reclassifications When necessary, reclassifications have been made to our prior period financial information to conform to the current year presentation and are not material to our consolidated financial statements.
