Long-Lived Asset Impairment
Long-Lived Asset Impairment	13. Long-Lived Asset Impairment During 2013, we evaluated the future deployment of our idle fleet and determined to retire and either sell or re-utilize the key components of approximately 280 idle compressor units, representing approximately 76,000 horsepower, previously used to provide services in our North America contract operations segment. As a result, we performed an impairment review and recorded a $14.9 million 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. In July 2013, as part of our continued emphasis on simplification and focus on our core business, we sold the entity that owned our fabrication facility in the United Kingdom. As a result, we recorded impairment charges of $11.9 million during the year ended December 31, 2013. During 2013, we evaluated other long-lived assets for impairment and recorded long-lived asset impairments of $1.8 million on these assets. During 2012, we evaluated the future deployment of our idle fleet and determined to retire and either sell or re-utilize the key components of approximately 930 idle compressor units, representing approximately 318,000 horsepower, previously used to provide services in our North America contract operations segment. As a result, we performed an impairment review and recorded a $97.1 million 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. In connection with our 2012 fleet review, we evaluated for impairment idle units that had been culled from our fleet in prior years and were available for sale. Based upon that review, we reduced the expected proceeds from disposition for most of the remaining units and increased the weighted average disposal period for the units from the assumptions used in prior periods. This resulted in an additional impairment of $34.8 million to reduce the book value of each unit to its estimated fair value. During 2012, we evaluated other long-lived assets for impairment and recorded long-lived asset impairments of $4.7 million on these assets. During 2011, we reviewed our idle compression assets used in our contract operations segments for units that were not of the type, configuration, make or model that are cost effective to maintain and operate. As a result, we performed an impairment review and recorded a $5.7 million 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. During 2011, we evaluated other long-lived assets for impairment and recorded long-lived asset impairments of $0.4 million on these assets.
