U.S. GAAP Reconciliations 32 Non - GAAP Financial Measures included in 2018 Guidance The Company's fiscal 2018 guidance for adjusted non - GAAP EBITDA and adjusted non - GAAP diluted earnings per share is not reconciled to the most comparable GAAP measure. This is due to the inherent difficulty of forecasting the timing or amount of items that would be included in a reconciliation to the most directly comparable forward - looking GAAP financial measures. Because a reconciliation is not available without unreasonable effort, it is not included in this presentation.
