During August 2020, we performed an engine overhaul on one of our energy assets, however, the engine consistently failed to achieve emissions compliance and we considered the engine unsalvageable. As a result of this event, we performed an impairment analysis on this energy asset group within the Non-Solar DG segment and recorded an impairment charge of $1,028, which fully impaired this asset group. The impairment charge is included in selling, general and administrative expenses within the consolidated statements of income for the year ended December 31, 2020.
We assessed the impact that the current macroeconomic environment surrounding the COVID-19 pandemic has or is expected to have on the business, and concluded that it was not a triggering event for impairment purposes and there was no indication of impairment of long-lived assets, except as indicated above, for the year ended December 31, 2020.
As of December 31, 2020 and 2019, there were three ESPC asset projects which were included in energy assets, net. We control and operate the assets as well as obtain financing during the construction period of the assets. We record a liability associated with these energy assets as we have an obligation to the customer for performance of the asset, although, the customer is responsible for payments to the lender based on the energy asset’s production.
The liabilities recognized in association with these ESPC assets were as follows:
December 31,
Location 2020 2019
Accrued expenses and other current liabilities $ 229  $ 827 
Other liabilities 10,794  9,416 
Total ESPC projects liability $ 11,023  $ 10,243
