(a) | “Other” includes (i) our Strategic Business Solutions (‘WMSBS”) business; (ii) those elements of our landfill gas-to-energy operations and third-party subcontract and administration revenues managed by our Energy and Environmental (“EES”) and WM Renewable Energy businesses that are not included in the operations of our reportable segments; (iii) our recycling brokerage services and (iv) certain other expanded service offerings and solutions. In addition, our “Other” segment reflects the results of non-operating entities that provide financial assurance and self-insurance support for our Solid Waste business, net of intercompany activity.
Income from operations for the Other segment for the twelve months ended December 31, 2020 was impacted primarily by an increase in revenue for (i) our WMSBS business as a result of new contract activities in the current year periods and (ii) our WM Renewable Energy business, as a result of a new renewable energy facility coming online, which drove an increase in commodity sales. Additionally, the twelve month period is impacted by a $16 million non-cash charge to write off certain equipment costs recorded in the prior year period offset, in part, by (i) a decrease in revenue within our EES business and (ii) the non-cash impairment of certain assets within our WM Renewable Energy business in the current year period.
(b) | Corporate operating results reflect certain costs incurred for various support services that are not allocated to our reportable segments. These support services include, among other things, treasury, legal, digital, tax, insurance, centralized service center processes, other administrative functions and the maintenance of our closed landfills. Income from operations for “Corporate and Other” also includes costs associated with our long-term incentive program and any administrative expenses or revisions to our estimated obligations associated with divested operations.
(c) | Intercompany operating revenues reflect each segment’s total intercompany sales, including intercompany sales within a segment and between segments. Transactions within and between segments are generally made on a basis intended to reflect the market value of the service.
(d) | For those items included in the determination of income from operations, the accounting policies of the segments are the same as those described in Note 3.
(e) | The income from operations provided by our Solid Waste business is generally indicative of the margins provided by our collection, landfill, transfer and recycling lines of business. From time to time, the operating results of our reportable segments are significantly affected by certain transactions or events that management believes are not indicative or representative of our results. In 2020, we revised allocations between our segments including (i) the discontinuation of certain allocations from Corporate and Other to Solid Waste and (ii) allocating certain insurance costs from Other to Solid Waste. Reclassifications have been made to our prior period information for comparability purposes.
In the second quarter of 2020, we recognized $61 million of non-cash impairment charges, including $41 million related to our energy services assets in our Tier 1 segment. Refer to Note 12 for additional information. Our 2020 operating results were also negatively impacted by revenue declines, as a result of the COVID-19 pandemic, in our landfill and industrial and commercial collection businesses beginning in March 2020 and continuing through the date of this report, although we began to experience improvement in volumes during the second half of 2020 when compared to the more acute impacts we experienced earlier in the year.
(f) | Includes non-cash items. Capital expenditures are reported in our reportable segments at the time they are recorded within the segments’ property and equipment balances and, therefore, may include amounts that have been accrued but not yet paid.
(g) | The reconciliation of total assets reported above to total assets in the Consolidated Balance Sheets as of December 31 is as follows (in millions):
​
