Biggest changeSome of these limitations are: • Adjusted EBITDA does not consider any expenses for assets being depreciated and amortized that are necessary to our business; • Adjusted EBITDA does not consider the impact of income tax provisions or benefits, other income/expense, stock-based compensation and related taxes, amortization of acquired intangible assets and other acquisition-related charges, restructuring charges and certain litigation costs that are not recurring in nature; and • Other companies, including companies in our industry, may calculate Adjusted EBITDA differently, which reduces its usefulness as a comparative measure.
Biggest changeSome of these limitations are: • Adjusted EBITDA does not consider the impact of interest and other income/expense and does not reflect income tax payments that may represent a reduction in cash available to us; • Adjusted EBITDA does not consider any expenses for assets being depreciated and amortized that are necessary to our business; although these are non-cash charges, the property and equipment being depreciated and amortized often will have to be replaced in the future, and Adjusted EBITDA does not reflect any cash capital expenditure requirements for such replacements; • Adjusted EBITDA and non-GAAP net income exclude stock-based compensation expense and related payroll taxes because we believe these adjustments provide better comparability to peer company results and because these charges are not viewed by management as part of our core operating performance ; • Adjusted EBITDA and non-GAAP net income exclude acquisition-related costs including the amortization of acquired intangible assets, as well as third-party transaction costs incurred for legal and other professional services, and an acquisition-related income tax benefit.
