All of the $12 million in unrealized losses at September 30, 2012 arose within the last 12 months and are related to the Company’s investment in two securities.  The market value of the available-for-sale equity securities that have been in an unrealized loss position for less than 12 months is $108 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 September 30, 2012.
