Non-GAAP Information Certain non-GAAP measures are included in this presentation, including EBITDA, non-GAAP operating income and Adjusted EBITDA. We define EBITDA as GAAP net income (loss) plus income tax expense (benefit), net interest expense and depreciation and amortization expense. Non-GAAP operating income does not include impairment of goodwill, amortization of intangibles, restructuring charges, stock-based compensation expense and other infrequent or unusual charges. These non-GAAP measures are provided to enhance the user’s overall understanding of our financial performance. By excluding these charges our non-GAAP results provide information to management and investors that is useful in assessing NAPCO’s core operating performance and in comparing our results of operations on a consistent basis from period to period. The presentation of this information is not meant to be a substitute for the corresponding financial measures prepared in accordance with generally accepted accounting principles.
