Significant estimates, assumptions, and judgments are used for, but not limited to: revenue recognition, share-based compensation expense including grant-date fair value of PSUs with a market-based condition and estimated forfeitures, accounting for income taxes, useful lives assigned to long-lived assets for depreciation and amortization, impairment of goodwill and long-lived assets, the valuation of acquired intangible assets, and internal-use software and website development costs. We base our estimates on historical experience, knowledge of current business conditions, and various other factors we believe to be reasonable under the circumstances. These estimates are based on management’s knowledge about current events and expectations about actions we may undertake in the future. Actual results could differ from these estimates, and such differences could be material to our financial position and results of operations.</span></div>
