Includes an impairment loss aggregating $853 thousand primarily related to investment in two private life science companies. During the three months ended December 31, 2013, we reduced the cost basis of an investment in a life science company from $350 thousand to zero. The cost basis of this investment was reduced by $400 thousand and $200 thousand in aggregate during the years ended December 31, 2012 and 2011, respectively, to our estimate of fair value as of the date of each reduction. During the three months ended December 31, 2013, we also reduced the cost basis of another investment in a life science company by $488 thousand to its estimated fair value. This life science company was subsequently acquired by a public company in the first quarter of 2014 at a value approximating our cost basis.
