Impairment charges are as follows (in millions):

	Year Ended December 31,

Impairment charges	$	2	$	86	$	2

During the year ended December 31, 2018, we identified an indicator of impairment associated with certain of our EfW facilities where the current expectation is that, more likely than not, the assets will not be operated through their previously estimated economic useful life. We performed recoverability tests to determine if these facilities were impaired as of the respective balance sheet date. As a result, based on expected cash flows utilizing Level 3 inputs, we recorded a non-cash impairment charge for the year ended December 31, 2018 of $86 million, to reduce the carrying value of the assets to their estimated fair value.

For more information regarding fair value measurements, see Note 12. Financial Instruments.
