During the three months ended March 31, 2011, we determined that certain patents within our portfolio in the United States and Europe had no value based upon an analysis of expected economic benefits. As a result, we recorded an impairment charge of $0.1 million for the write-down of these patents. During the three months ended June 30, 2010, we incurred $0.1 million of impairment charges related to a customer relationship associated with our Biomateriali subsidiary based upon an analysis of expected economic benefits.
