On an ongoing basis, we reconsider and evaluate our estimates and assumptions, including those that impact revenue recognition, long-lived and intangible assets, income taxes, business combinations, stock-based compensation, capitalization of software development costs, our allowances for credit losses and sales returns, costs of obtaining contracts, valuation of derivative instruments, loss contingencies and insurance recoveries, among others. Changes in the facts or circumstances underlying these estimates could result in material changes and actual results could materially differ from these estimates.</span></div>
