As a result, we performed an impairment review and recorded a $2.5 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.   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 260 idle compressor units, representing approximately 69,000 horsepower, that we previously used to provide services. As a result, we performed an impairment review and recorded a $21.5 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 $7.4 million to reduce the book value of each unit to its estimated fair value.   </div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for the details of the charge against earnings resulting from the aggregate write down of all assets from their carrying value to their fair value.
