We define segment profit as segment revenues less costs of services, segment selling, general and administrative, depreciation and amortization, and other income (excluding the movement in foreign currency exchange rates on our foreign currency denominated assets and liabilities and the related economic hedges). The Company does not allocate to its segments certain operating expenses managed at the corporate level. These unallocated costs generally include certain corporate function costs, stock-based compensation expense, pension and other post-retirement benefits (“OPEB”) actuarial and settlement gains and losses, restructuring costs, transaction, separation and integration-related costs, and amortization of acquired intangible assets.
