Non-GAAP Adjusted EBITDA is defined as earnings before interest, income taxes, depreciation and amortization, acquisition-related transaction costs and stock-based compensation. It is presented as a supplemental measure of the Company’s performance. However, Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of the Company’s results as reported under GAAP.Non-GAAP Adjusted Net Income is defined as net income before stock-based compensation, acquisition-related transaction costs and amortization of purchased intangibles and any tax impact related to these items. Non-GAAP Adjusted Net Income Per Diluted Share is defined as Non-GAAP Adjusted Net Income divided by the weighted average diluted shares outstanding. Management considers all of these non-GAAP financial measures to be useful indicators of the Company’s performance and a measure of historical trends. The following items are excluded from non-GAAP Adjusted Net Income and related Per Diluted Share financial measures referenced above, and the reasons therefore are:
- Stock-based compensation — Excluded because these are non-cash expenses that management does not consider useful in assessing ongoing operating results or performance of the business, and also because the amount of the expense is not totally within the Company’s control since it is based on factors such as stock price, volatility and interest rates which may be unrelated to the Company’s performance during the period the expense is incurred.
- Amortization of purchased intangibles — Purchased intangibles are amortized over their estimated useful life and generally cannot be influenced after the acquisition. Accordingly, this item is not considered by management in making operating decisions. Thus, including such charges does not accurately reflect the performance for the period in which such charge is incurred.
- Acquisition-related transaction costs — Transaction costs associated with acquisitions are non-recurring and related specifically to a subject acquisition. Accordingly, management does not believe that they reflect the underlying performance of ongoing business operations for the period incurred.
