​ During the year ended December 31, 2023, we recognized $243 million of net charges primarily consisting of (i) a $168 million goodwill impairment charge within our Recycling Processing and Sales segment related to a business engaged in accelerating film and plastic wrap recycling capabilities, with $22 million attributable to noncontrolling interests. This charge was partially offset by the recognition of $46 million of income related to the reversal of a liability for contingent consideration associated with our investment in such business; (ii) $107 million of impairment charges within Corporate and Other for certain investments in waste diversion technology businesses and (iii) a $17 million charge within Corporate and Other to adjust an indirect wholly-owned subsidiary’s estimated potential share of the liability for a proposed environmental remediation plan at a closed site. Refer to Notes 5 and 10 for further information. During the year ended December 31, 2022, we recognized $62 million of net charges consisting of (i) $50 million of asset impairment charges primarily related to management’s decision to close two landfills within our East Tier and (ii) a $17 million charge pertaining to reserves for loss contingencies within Corporate and Other to adjust an indirect wholly-owned subsidiary’s estimated potential share of the liability for a proposed environmental remediation plan at a closed site, as discussed in Note 10. These losses were partially offset by a $5 million gain from the divestiture of a collection and disposal business in our West Tier. During the year ended December 31, 2021, we recognized net gains of $16 million primarily consisting of (i) a $35 million pre-tax gain from the recognition of cumulative translation adjustments on the divestiture of certain non-strategic Canadian operations in our East Tier and (ii) an $8 million gain from divestitures of certain ancillary operations within our Collection and Disposal businesses. These gains were partially offset by (i) a $20 million charge pertaining to reserves for loss contingencies within Corporate and Other and (ii) $8 million of asset impairment charges primarily related to our WM Renewable Energy segment. See Note 2 for additional information related to the accounting policy and analysis involved in identifying and calculating impairments. See Note 19 for additional information related to the impact of impairments on the results of operations of our reportable segments. Equity in Net Losses of Unconsolidated Entities The losses for the reported years were primarily related to our noncontrolling interests in entities established to invest in and manage low-income housing properties. We generate tax benefits, including tax credits, from the losses incurred from these investments. The losses are more than offset by the tax benefits generated by these investments as further discussed in Note 8. Refer to Notes 8 and 18 for additional information related to these investments. Refer to (Gain) Loss from Divestitures, Asset Impairments and Unusual Items, Net above for more information on the impairment of an equity method investment.
