Revenue and segment income from continuing operations

Segment income from operations, as shown below, is the performance measure used by management to assess segment performance and excludes the effects of stock-based compensation, amortization of intangible assets and corporate expenses, as these items are excluded from the segment performance measures utilized by the Company's chief operating decision maker in evaluating the performance of the segments. Corporate expenses consist of those costs not directly attributable to a business segment, and include: salaries and benefits for the Company’s executive, finance, legal, corporate governance, human resources, and facilities organizations; fees for professional service providers including audit, tax and Sarbanes-Oxley compliance; certain legal fees not directly attributable to a business segment; insurance; acquisition related costs; and, other corporate expenses.
