In the fourth quarter of fiscal 2013, as a result of a contraction in the Brazil economy, the Company experienced reduced demand for inspection services and a decline in recent and projected operating results. As a result of the completion of step one of the impairment analysis, the Company concluded that, as of March 1, 2013, the fair value of the Brazil reporting unit was below its respective carrying value and the step two analysis was performed. As a result, the Company recorded a goodwill impairment charge in the amount of $9.9 million in fiscal 2013, within its International segment, which also represents the Company's cumulative impairment charge as of May 31, 2015.
