All of the $4 million in unrealized losses at June 30, 2011 arose within the last 12 months. The market value of the investments that have been in an unrealized loss position for less than 12 months is $9 million. The $4 million in unrealized losses associated with available-for-sale equity securities is related to the Company’s investment in one security. The Company evaluated the near-term prospects of the issuer in relation to the severity and duration of the impairment. Based on that evaluation and the Company’s ability and intent to hold this investment for a reasonable period of time sufficient for a forecasted recovery of fair value, the Company does not consider this investment to be other-than-temporarily impaired at June 30, 2011.
