Item 3. Legal Proceedings

Please see Note 20 to our Consolidated Financial Statements in this Annual Report for a description of our legal proceedings, which is incorporated by reference herein.

We are subject to various environmental laws and regulations both within and outside of the United States. Our operations, like those of other medical device companies, involve the use of substances regulated under environmental laws, primarily in manufacturing and sterilization processes. While it is difficult to quantify the potential impact of continuing compliance with environmental protection laws, management believes that such compliance will not have a material impact on our financial results. Our threshold for disclosing material environmental legal proceedings involving a governmental authority where potential monetary sanctions are involved is $1 million.
