On an on-going basis, the Group evaluates its estimates, including those related to the useful lives of long-lived assets including property and equipment, stock-based compensation, fair value of assets and liabilities acquired in business combinations, impairment of intangible assets and other long-lived assets, income taxes and provision for doubtful accounts. The Group bases its estimates of the carrying value of certain assets and liabilities on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, when these carrying values are not readily available from other sources. Actual results may differ from these estimates.</p>
