Non-GAAP Financial Measure

This press release contains a discussion of consolidated segment profit that would be deemed a non-GAAP financial measure under SEC rules. Segment profit is calculated as revenue less cost of revenue and earnings attributable to noncontrolling interests excluding: corporate general and administrative expense; interest expense; interest income; domestic and foreign income taxes; and other non-operating income and expense items. The company believes that consolidated segment profit provides a meaningful perspective on its business results as it is the aggregation of individual segment profit measures that the company utilizes to evaluate and manage its business performance. A reconciliation of this measure to earnings (loss) before taxes is included in the press release tables.
