Reconciliation of Operating Income/Margin Before Reconciliation of Operating Income/Margin Before Restructuring to Operating Income/MarginRestructuring to Operating Income/Margin

Operating income before restructuring and operating margin before restructuring are non-GAAP financial measures. They are not intended as substitutes for GAAP financial measures. The Company has provided this supplemental non-GAAP financial information because it provides meaningful information regarding the Company’s results on a consistent and comparable basis for the periods presented. The Company believes investors use this information to evaluate period-to-period results and to understand potential future operating results. The Company encourages investors and other users of this information to review the Company’s financial statements and other information contained within its reports filed with the Securities and Exchange Commission and not to rely on any single financial measure. A reconciliation of the non-GAAP financial measure to the most comparable GAAP measure is set forth on the next slide.
