¹ The company’s projected adjusted cash earnings calculation excludes from its GAAP earnings amortization of intangible assets, stock-based compensation, restructuring expenses (income), and extraordinary items, if any, and employs the company’s actual tax provision. The company believes its adjusted cash earnings calculations are meaningful as they exclude any noncash charges which the company believes are not necessarily indicative of the performance of the company’s underlying business. Management believes the presentation of earnings excluding these charges provides useful information to investors as measures of operating performance basic to the company’s ongoing operations and comparable from period to period. The following table reconciles projected adjusted cash earnings per share to GAAP earnings per share:
