(1) In fiscal year 2014, we recovered a portion of the purchase price holdback amount we had previously paid and were relieved of any potential contingent consideration obligation associated with the acquisition of an industrial service management business completed earlier in fiscal year 2014. As a result, we recorded a $1,058 gain on settlement of acquisition related contingent consideration in fiscal year 2014.
