All of the $38 million in unrealized losses at March 31, 2013, arose within the last 12 months and are related to the Company’s investment in three available-for-sale equity securities with a market value of $571 million.  The Company evaluated the near-term prospects of the issuers in relation to the severity and duration of the impairment.  Based on that evaluation and the Company’s ability and intent to hold these investments for a reasonable period of time sufficient for a forecasted recovery of fair value, the Company does not consider these investments to be other-than-temporarily impaired at March 31, 2013.
