The Company generally does not require its customers to provide collateral or other security to support accounts receivable. To manage credit risk, management performs ongoing credit evaluations of its customers’ financial condition.  The Company requires cash in advance for certain customers in addition to ongoing credit evaluations for those where credit has been extended.

Significant estimates and assumptions used in these consolidated financial statements primarily include those related to revenue recognition, inventory valuation, valuation of share-based awards, valuation of goodwill and acquisition-related intangible assets, contingencies and tax valuation allowances. Actual results could differ from those estimates.</div></div></div></div></div></div></div></div></div></div></div></div></div></div>
