Significant estimates made by management include estimation for reserves for legal contingencies, the standalone selling price related to revenue recognition, the provision for credit losses related to accounts receivable, contract assets, and available-for-sale debt securities, the provision to reduce obsolete or excess inventory to net realizable value, the provision for estimated returns, as well as sales allowances, the assumptions used in the valuation of stock-based awards and measurement of expense related to performance stock units, the assumptions used in the discounted cash flows to mark certain of its investments to market, the valuation of the Company’s goodwill, net realizable value of product related and other intangible assets, the provision for income taxes, valuation allowance for deferred tax assets, uncertain tax positions, and the amortization and depreciation periods for contract acquisition costs, intangible and long-lived assets. While the Company believes that such estimates are fair when considered in conjunction with the consolidated financial position and results of operations taken as a whole, the actual amounts of such items, when known, will vary from these estimates.</span></div>
