The $1 million in unrealized losses at June 30, 2015 is related to the Company’s investment in one available-for-sale equity security that has been in an unrealized loss position for 12 months or longer with a fair value of $5 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 June 30, 2015.
