Non-GAAP Measures

In evaluating the business, the company considers and uses non-GAAP measures, such as non-GAAP gross profit and non-GAAP gross margin, as supplemental measures to review and assess operating performance. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The company defines non-GAAP gross profit as gross profit excluding depreciation and amortization. The company defines non-GAAP gross margin as gross margin excluding depreciation and amortization.

The company presents these non-GAAP financial measures because they are used by management to evaluate operating performance and formulate business plans. The company believe non-GAAP gross profit and non-GAAP gross margin excluding non-cash impact of depreciation and amortization reflect the company’s ongoing business operations in a manner that allows more meaningful period-to-period comparisons.
