During the year ended December 31, 2014, we recognized a $2.2 million gain on the sale of detector tube assets. See Note 19 for further information. During the year ended December 31, 2013, impairment charges were taken on land not used in operations. During the year ended December 31, 2012, we settled an escrow claim for indemnification with the sellers of General Monitors. Under the terms of the settlement, we received $4.8 million in December 2012. The settlement proceeds have been recognized in other income because the settlement occurred after the business combination measurement period ended. The escrow agreement has now expired and the remaining escrow account balance was released to the sellers. In addition, we recognized gains on the sale of assets totaling $8.4 million in 2012. These gains were primarily related to property sales in our Cranberry Woods office park. We also recognized a $4.3 million intangible asset impairment loss in 2012 when we discontinued our firefighter location development project.
