We hold equity investments in certain publicly traded companies and privately held entities primarily involved in the life science industry.  Investments in “available for sale” securities with gross unrealized losses as of June 30, 2012, had been in a continuous unrealized loss position for less than 12 months.  We have the ability and intent to hold these investments for a reasonable period of time sufficient for the recovery of our investment.  We believe that these unrealized losses are temporary, and accordingly we have not recognized an other-than-temporary impairment related to “available for sale” securities as of June 30, 2012.  As of June 30, 2012, and December 31, 2011, there were no unrealized losses in our investments in privately held entities.
