We have revised our prior period segment information to reflect this reorganization and a related reclassification of certain Corporate expenses. See Note </font><font style="font-family:Arial;font-size:10pt;">18</font><font style="font-family:Arial;font-size:10pt;">, “Segment and Geographic Information,” for further details. Concurrent with the reorganization, we recategorized certain expenses that were historically included in operating expenses to selling, general and administrative expenses. To conform to the new categorization, we reclassified operating expenses of </font><font style="font-family:Arial;font-size:10pt;">$20.0 million</font><font style="font-family:Arial;font-size:10pt;"> and </font><font style="font-family:Arial;font-size:10pt;">$17.7 million</font><font style="font-family:Arial;font-size:10pt;"> for 2016 and 2015, respectively, to selling, general and administrative expenses. In addition, based on the terms of the agreement to sell the Government Services business, we reclassified certain of the prior year amounts in the accompanying consolidated balance sheets and statements of cash flows from held-for-sale to held-and-used.</font></div></div>
