Our United Kingdom building services segment recognized income of $4.8 million during the second quarter of 2014, which has been recorded as a reduction of "Cost of sales" in the Consolidated Statements of Operations for the year ended December 31, 2014, as a result of a reduction in the estimate of certain accrued contract costs that were no longer expected to be incurred within its building services operations. Our corporate administration operating loss for the year ended December 31, 2013 was reduced by the receipt of an insurance recovery of approximately $2.6 million that was received in January 2013 associated with a previously disposed of operation, which is classified as a component of "Cost of sales" in the Consolidated Statements of Operations.
