These estimates and judgments, include but are not limited to, revenue recognition (specifically sales returns and other allowances); valuation of goodwill and acquired intangible assets; accounting for business combinations; evaluating loss contingencies; and accounting for income taxes and related valuation allowances. The Company bases these estimates and judgments on historical experience, market participant fair value considerations, projected future cash flows and various other factors that the Company believes are reasonable under the circumstances. Actual results may differ from the Company’s estimates. </font></div></div>
