Actual results could differ from these estimates. Significant estimates include excess or obsolete inventories, valuation of inventory, warranty accruals, employee bonus, clinical study expenses, allowances for returned product, allowance for bad debt, deferral period for recognizing revenue on future performance obligations, accounting for the SweetSpot acquisition including contingent consideration, and share-based compensation expense. Excess and obsolete inventories are estimated by identifying the amount of on hand and on order materials compared to expected future sales, taking into account clinical trial and development usage along with new product introductions. Employee bonus estimates are based, in part, on the 2012 bonus plan’s authorized target bonus amounts to be awarded from the bonus pool based on the weighted average achievement of certain objectives. Clinical trial expenses are accrued based on estimates of progress under related contracts and include initial set up costs as well as ongoing monitoring over multiple sites in the U.S. and abroad. An allowance for refunds for returned products is determined by analyzing the timing and amounts of past refund activity and considering the impact of newly introduced products.</font></p> </div>
