Divestitures, Asset Impairments and Unusual Items	9. Divestitures, Asset Impairments and Unusual Items (Gain) Loss from Divestitures, Asset Impairments and Unusual Items, Net During the nine months ended September 30, 2021, we recognized net gains of $17 million consisting of (i) a $35 million pre-tax gain in the third quarter of 2021 from the recognition of cumulative translation adjustments on the divestiture of certain non-strategic Canadian operations in our Tier 3 segment and (ii) an $8 million gain in the first quarter of 2021 from divestitures of certain ancillary operations in our Other segment. These gains were partially offset by (i) a $20 million charge pertaining to reserves for loss contingencies in our Corporate and Other segment and (ii) $6 million of asset impairment charges primarily related to our WM Renewable Energy business within our Other segment. During the nine months ended September 30, 2020, we recognized non-cash impairment charges of $68 million primarily related to the following: Energy Services Asset Impairments— During the second quarter of 2020, the Company tested the recoverability of certain energy services assets in our Tier 2 segment. Indicators of impairment included (i) the sharp downturn in oil demand that has led to a significant decline in oil prices and production activities, which we project will have long-term impacts on the utilization of our assets and (ii) significant shifts in our business, including increases in competition and customers choosing to bury waste on site versus in a landfill, reducing our revenue outlook. The Company determined that the carrying amount of the asset group was not fully recoverable. As a result, we recognized $41 million of non-cash impairment charges primarily related to two landfills and an oil field waste injection facility in our Tier 2 segment. We wrote down the net book value of these assets to their estimated fair value using an income approach based on estimated future cash flow projections (Level 3). The aggregate fair value of the impaired asset group was $8 million as of June 30, 2020. Other Impairments — In addition to the energy services impairments noted above, during the second quarter of 2020, we recognized a $20 million non-cash impairment charge in our Tier 3 segment due to management’s decision to close a landfill once its constructed airspace is filled and abandon any remaining permitted airspace, which was considered an impairment indicator. As the carrying value was not recoverable, we wrote off the entire net book value of the asset using an income approach based on estimated future cash flow projections (Level 3). The impairment charge was comprised of $12 million related to the carrying value of the asset and $8 million related to the acceleration of the expected timing of capping, closure and post-closure activities. Additionally, during the third quarter of 2020, we recognized $7 million of net charges primarily related to non-cash impairments of certain assets within our WM Renewable Energy business in our Other segment. As the carrying values of the assets were not recoverable, we wrote off their entire net carrying value using an income approach based on estimated future cash flow projections (Level 3). Equity in Net Losses of Unconsolidated Entities During the first quarter of 2020, we recorded a non-cash impairment charge of $7 million related to our investment in a refined coal facility which is discussed further in Note 4. The fair value of our investment was not readily determinable; thus, we determined the fair value using management assumptions pertaining to investment value (Level 3). The remaining losses for each period 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. Refer to Note 4 for additional information related to these investments.
