Non-GAAP Financial Measures
In addition to disclosing financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), this press release and the accompanying tables contain certain non-GAAP financial measures. We calculate adjusted gross profit and adjusted gross margin by adding back the following items to gross profit: depreciation, intangibles amortization, stock-based compensation, acquisition and related transaction costs and one-time integration costs, lease amortization for finance leases, and costs related to a reduction in force plan. We calculate adjusted EBITDA by adding back or removing the following items to or from GAAP net income (loss): depreciation and amortization, stock-based compensation, interest expense, gain on early extinguishment of debt, interest income and other, exit costs related to closure and relocation of our Russian operations, acquisition and related transaction costs and one-time integration costs, lease amortization for finance leases, costs related to a reduction in force plan, one-time expenses related to strategic consulting services for operational review, other cost-reduction and productivity initiatives, legal fees related to the securities class action, office closure lease termination costs, and provision for income taxes. We calculate non-GAAP operating income by adding back or removing the following items to or from GAAP loss from operations: stock-based compensation, intangibles amortization, exit costs related to the closure and relocation of our Russian operations, acquisition related transaction costs and one-time integration costs, costs related to a reduction in force plan, one-time expenses related to strategic consulting services for operational review, other cost-reduction and productivity initiatives, legal fees related to the securities class action, and office closure lease termination costs. We calculate non-GAAP net income by adding back or removing the following items to or from GAAP net loss: stock-based compensation, intangibles amortization, amortization of discount and issuance costs on convertible senior notes, gain on early extinguishment of debt, exit costs related to the closure and relocation of our Russian operations, acquisition and related transaction costs and one-time integration costs, costs related to a reduction in force plan, one-time expenses related to strategic consulting services for operational review, other cost-reduction and productivity initiatives, legal fees related to the securities class action, and office closure lease termination costs. For the periods presented, these adjustments from GAAP net income (loss) to non-GAAP net income do not include any presentation of the net tax effect of such adjustments given our significant net operating loss carryforwards. Non-GAAP financial measures do not have any standardized meaning and are therefore
3


unlikely to be comparable to similarly titled measures presented by other companies. The Company considers these non-GAAP financial measures to be important because they provide useful measures of the operating performance of the Company, exclusive of factors that do not directly affect what we consider to be our core operating performance, as well as unusual events. The Company’s management uses these measures to (i) illustrate underlying trends in the Company’s business that could otherwise be masked by the effect of income or expenses that are excluded from non-GAAP measures, and (ii) establish budgets and operational goals for managing the Company’s business and evaluating its performance. In addition, investors often use similar measures to evaluate the operating performance of a company. Non-GAAP financial measures are presented only as supplemental information for purposes of understanding the Company’s operating results. The non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP. Please see the reconciliation of non-GAAP financial measures set forth in this release.
