(a) | 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.
Income from operations in our Solid Waste business increased in 2022, as compared with 2021, primarily due to revenue growth in our collection and disposal businesses driven by both yield and volume. This increase was partially offset by (i) inflationary cost pressures; (ii) labor cost increases from frontline employee wage adjustments; (iii) divestitures, asset impairments and unusual items, discussed in Note 11 above, that impacted our East Tier results and (iv) reduced profitability in our recycling business from the decline in recycling commodity prices and lower volumes. Income from operations in our Solid Waste business increased in 2021, as compared with 2020, primarily due to (i) revenue growth in our collection and disposal businesses driven by both yield and volume, as well as the acquisition of Advanced Disposal; (ii) improved profitability in our recycling business from higher market prices for recycling commodities and improved costs at facilities where we have made investments in enhanced technology and equipment and (iii) changes from divestitures, asset impairments and unusual items, discussed in Note 11, that impacted both Tiers’ results. These increases were partially offset by (i) labor cost pressure from frontline employee wage adjustments, increased turnover driving up training costs and higher overtime due to driver shortages and volume growth; (ii) increased landfill depletion from higher volumes and revisions in landfill estimates, including the anticipated timing of capping, closure and post-closure activities at certain landfills and adjustments in 2020 to the inflation rate used to estimate capping, closure, and post-closure asset retirement obligations that benefitted costs in 2020 and (iii) inflationary cost pressures. During 2021, the positive earnings contributions from Advanced Disposal were offset by elevated depreciation, depletion and amortization of acquired assets.
(b) | “Other” includes (i) elements of our Strategic Business Solutions (“WMSBS”) business that are not included in the operations of our reportable segments; (ii) elements of our sustainability business that includes landfill gas-to-energy operations managed by our WM Renewable Energy business, our SES business and recycling brokerage services and not included in the operations of our reportable segments; (iii) certain other expanded service offerings and solutions and (iv) the results of non-operating entities that provide financial assurance and self-insurance support for our Solid Waste business, net of intercompany activity.
The decrease in income from operations in 2022, as compared with 2021, was due to the recognition of acquisition and integration-related costs, as well as, a prior year gain from divestitures of certain ancillary operations in our Other segment, discussed in Note 11, partially offset by improved profitability in our SES and WMSBS businesses. The increase in income from operations for 2021, as compared to 2020, was primarily driven by increased market values for renewable energy credits generated by our WM Renewable Energy business.
(c) | “Corporate and other” 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.
These costs increased in 2022, as compared with 2021, primarily due to strategic investments in our digital platform and sustainability initiatives, partially offset by lower acquisition and integration related costs. These costs increased in 2021, as compared with 2020, due to (i) higher incentive compensation costs; (ii) increased labor, support and integration costs following our acquisition of Advanced Disposal; (iii) strategic investments in our digital platform; (iv) increased health and welfare costs attributable to medical care activity generally returning to pre-pandemic levels from the lower levels experienced during 2020 and (v) charges pertaining to reserves for certain loss contingencies during 2021. These increases were partially offset by lower consulting, advisory and legal fees following the completion of our acquisition of Advanced Disposal in the fourth quarter of 2020 and changes in the measurement of our environmental remediation obligations and recovery assets in both 2020 and 2021.
(d) | 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.
(e) | 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 2.
(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, include timing differences for amounts 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):

​ |  | 2022 |  | 2021 |  | 2020
