The accounting estimates that require management’s most significant, complex, and subjective judgments include the valuation and recognition of investments, revenue recognition and the valuation of revenue and allowances for sales returns and doubtful accounts, the valuation of inventory, the valuation of and assessment of recoverability of intangible assets and their estimated useful lives, the valuation and recognition of share-based compensation, the recognition and measurement of current and deferred income tax assets, along with the assessment of recoverability, and liabilities, and the estimates for legal contingencies.
