Well Positioned for the Future

The following information provides reconciliations of the supplemental non-GAAP financial measures, as defined under SEC rules, presented in this presentation to the most directly comparable financial measures calculated and presented in accordance with generally accepted accounting principles in the United States (GAAP). The company has provided these non-GAAP financial measures in the presentation, which are not calculated or presented in accordance with GAAP, as supplemental information in addition to the financial measures that are calculated and presented in accordance with GAAP. These supplemental non-GAAP financial measures are presented because management has evaluated the company’s financial results both including and excluding the adjusted items and believes that the non-GAAP financial measures presented provide additional perspective and insights when analyzing the core operating performance of the Company’s business from period to period and trends in the company’s historical operating results. The company does not provide a non-GAAP reconciliation for non-GAAP estimates on a forward-looking basis where it is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. The supplemental non-GAAP financial measures presented should not be considered superior to, as a substitute for or as an alternative to, and should be considered in conjunction with, the GAAP financial measures presented in the presentation.

1. Free cash flow is defined as net cash provided by operating activities in a period minus additions to property, plant and equipment (capital expenditures) made in that period. This measure does not represent residual cash flows available for discretionary expenditures as the measure does not deduct the payments required for debt service and other contractual obligations or payments for future business acquisitions. Therefore, we believe it is important to view free cash flow as a measure that provides supplemental information to our entire statements of cash flows. Reconciliation of Non-GAAP financial measures
