Note 12 - Contingencies

The medical device market in which we participate is largely technology driven. As a result, intellectual property rights, particularly patents, play a significant role in product development and differentiation. However, intellectual property litigation is inherently complex and unpredictable. Furthermore, appellate courts can overturn lower court patent decisions.

In addition, competing parties may file suits to balance risk and exposure between the parties. Adverse outcomes in proceedings against us could limit our ability to sell certain products in certain jurisdictions, or reduce our operating margin on the sale of these products and could have a material adverse effect on our financial position, results of operations or liquidity.

In addition, although monetary and injunctive relief is typically sought, remedies and restitution are generally not determined until the conclusion of the trial court proceedings and can be modified on appeal. Accordingly, the outcomes of individual cases are difficult to time, predict or quantify.

We are not insured with respect to intellectual property infringement and maintain an insurance policy providing limited coverage against securities claims and product liability claims. The absence of significant third-party insurance coverage increases our potential exposure to unanticipated claims or adverse decisions.

We continually assess litigation to determine if an unfavorable outcome would lead to a probable loss or reasonably possible loss which could be estimated. In accordance with the FASB's guidance on accounting for contingencies, we accrue for all direct costs associated with the estimated resolution of contingencies at the earliest date at which it is deemed probable that a liability has been incurred and the amount of such liability can be reasonably estimated. If the estimate of a probable loss is a range and no amount within the range is more likely, we accrue the minimum amount of the range.
