Long-Lived Asset Impairment
Long-Lived Asset Impairment	9. Long-Lived Asset Impairment During the six months ended June 30, 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 170 idle compressor units, representing approximately 40,000 horsepower, that we previously used to provide services in our North America contract operations segment. As a result, we performed an impairment review and recorded a $7.1 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 the expected net sale proceeds compared to other fleet units we recently sold, as well as our 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, we sold the entity that owned our fabrication facility in the United Kingdom. As of June 30, 2013, all assets and liabilities of this entity met the criteria for held for sale and were reported at the lower of their carrying value or their fair value based on the net transaction value of the agreement entered into subsequent to the balance sheet date. As a result, we recorded impairment charges of $11.9 million to reduce the book value of the business to its estimated fair value. During the six months ended June 30, 2013, we evaluated other long-lived assets for impairment and recorded long-lived asset impairments of $1.1 million on these assets. During the six months ended June 30, 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 920 idle compressor units, representing approximately 316,000 horsepower, that we previously used to provide services in our North America contract operations segment. As a result, we performed an impairment review and recorded a $96.5 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 the expected net sale proceeds compared to other fleet units we recently sold, as well as our 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 review of our fleet in 2012, 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 the six months ended June 30, 2012, we evaluated other long-lived assets for impairment and recorded long-lived asset impairments of $1.5 million on these assets.
