These lawsuits seek a variety of remedies, including unspecified monetary damages. We are vigorously defending ourselves in these matters. During the three months ended September 30, 2016, we recorded an accrual, most of which relates to legal defense costs, as an adjustment to pre-acquisition liabilities assumed in the Cordis acquisition. Refer to Note 2 for further information regarding this adjustment. We do not believe that reasonably possible losses in excess of this accrued amount will be material to our financial statements.
