Long-Lived Asset Impairment

10.  Long-Lived Asset Impairment

We review long-lived assets, including property, plant and equipment and identifiable intangibles, that are being amortized for impairment whenever events or changes in circumstances, including the removal of compressor units from our active fleet, indicate that the carrying amount of an asset may not be recoverable.

During the three months ended March 31, 2017 and 2016, we reviewed the future deployment of our idle compression assets for units that were not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. Based on these reviews, we determined that certain idle compressor units would be retired from the active fleet. The retirement of these units from the active fleet triggered a review of these assets for impairment, and as a result of our review, we recorded an asset impairment to reduce the book value of each unit to its estimated fair value. The fair value of each unit was estimated based on either the expected net sale proceeds compared to other fleet units we recently sold and/or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment we plan to use.

The following table presents the results of our impairment review for the three months ended March 31, 2017 and 2016:

	Three Months Ended March 31,
	2017				2016
Retired idle compressor units within the active fleet	80				80
Horsepower of retired idle compressor units within the active fleet	28,000				33,000
Impairment recorded on retired idle compressor units within the active fleet (in millions)	$	8.2			$	9.9
