Non-GAAP Reconciliation The Company does not provide reconciliations of forward-looking non-GAAP financial measures, such as outlook for net debt to adjusted EBITDA leverage, to the most comparable GAAP financial measures on a forward-looking basis because the Company is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of certain items, such as, but not limited to, restructuring costs, environmental remediation costs, acquisition-related costs, and other non-routine costs.
