Disclosures about Segments of an Enterprise and Related Information. We conduct our business activities in seven business segments within the Mailstream Solutions and Mailstream Services business groups. As a result of these changes, we have reclassified the prior year amounts for the segment changes. EBIT is determined by deducting from revenue the related costs and expenses attributable to the segment. Segment EBIT excludes general corporate expenses, restructuring charges, interest expense, other income (expense) and income taxes.
