Actual results could differ from those estimates. The most significant management estimates used in the preparation of the accompanying consolidated financial statements are associated with the expected net collectable value of its accounts receivable and related revenue, inventory reserves, the life of its leased unit devices, stock-based compensation, valuation of long-lived assets acquired in business combinations, valuation of contingent consideration, and realizability of deferred tax assets.</p>
