​ ​ During the year ended December 31, 2020, we recognized $35 million of net charges primarily related to the following: Gain from Divestitures, Net — As discussed further in Note 18, we and Advanced Disposal entered into an agreement that provided for GFL Environmental to acquire a combination of assets from us and Advanced Disposal to address divestitures required by the U.S. Department of Justice in connection with our acquisition of Advanced Disposal (as subsequently amended, the “Divestiture Agreement”). Immediately following the closing of the Advanced Disposal acquisition, the transactions contemplated by the Divestiture Agreement were consummated and the Company subsequently received cash proceeds of $856 million, subject to certain post-closing adjustments. We recognized a net gain of $33 million on our net assets divested under the Divestiture Agreement, primarily within our Tier 2 segment. Energy Services Asset Impairments — During the second quarter of 2020, the Company tested the recoverability of certain energy services assets in our Tier 1 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 1 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. The Company tested the recoverability of an additional $239 million in energy services assets and determined that the carrying amount was recoverable as of June 30, 2020. No new indicators of impairment were identified during the second half of 2020. Other Impairments — In addition to the energy services impairments noted above, 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, which is discussed further in Note 4. 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). During the year ended December 31, 2019, we recognized asset impairments of $42 million, related to (i) $27 million of goodwill impairment charges of which $17 million related to our EES business and $10 million related to our LampTracker® reporting unit and (ii) $15 million of asset impairment charges primarily related to certain solid waste operations. During the year ended December 31, 2018, we recognized net gains of $58 million, primarily related to (i) a $52 million gain associated with the sale of certain hauling operations in our Tier 1 segment and (ii) net gains of $44 million substantially all from divestitures of certain ancillary operations. These gains were partially offset by (i) a $30 million charge to impair a landfill in our Tier 3 segment based on an internally developed discounted projected cash flow analysis, taking into account continued volume decreases and revised capping cost estimates and (ii) $8 million of impairment charges primarily related to our LampTracker® reporting unit. See Note 3 for additional information related to the accounting policy and analysis involved in identifying and calculating impairments. See Note 20 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 During the year ended December 31, 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 Notes 9 and 19. 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). Other, Net During the first quarter of 2019, we recognized a $52 million non-cash impairment charge related to our minority-owned investment in a waste conversion technology business. We wrote down our investment to its estimated fair value as the result of recent third-party investor’s transactions in these securities. The fair value of our investment was not readily determinable; thus, we determined the fair value utilizing a combination of quoted price inputs for the equity in our investment (Level 2) and certain management assumptions pertaining to investment value (Level 3).
