Actual results could differ from these estimates. Acacia believes that, of the significant accounting policies described herein, the accounting policies associated with revenue recognition, estimates of variable consideration for revenue, including sales returns, the valuation of equity securities without readily determinable fair value, the determination of excess and obsolete inventories, bad debt allowances and product warranty liabilities, the valuation of Series A redeemable convertible preferred stock (the “Series A Redeemable Convertible Preferred Stock”), embedded derivatives, Series A warrants (the “Series A Warrants”) and Series B warrants (the “Series B Warrants”), stock-based compensation expense, impairment of goodwill, patent-related and other intangible assets, the determination of the economic useful life of amortizable intangible assets, and income taxes and valuation allowances against net deferred tax assets, require its most difficult, subjective or complex judgments.</span></div>
