EBITDA is a Non-GAAP financial measure. EBITDA is defined as income (loss) from operations plus net interest expense, provision for income taxes, depreciation and amortization. EBITDA has certain material limitations, including:
For the purposes of performing the calculation of EBITDA, we may also add back all non cash equity based compensation.
We have included these non-GAAP financial measures, because we believe EBITDA and EBITDA plus non cash equity based compensation are indicators of the profitability and performance of our core operations and reflect the changes in our operating results. These Non-GAAP financial measures are not intended to be an alternative measure of operating income or gross profit margin as determined in accordance with generally accepted accounting principles. We compensate for these limitations by using Non-GAAP financial measures as only one of several comparative tools, together with GAAP measurements, to assist in the evaluation of our profitability and operating results.
