The Company's investments in marketable securities consist primarily of investments in common stock of entities in the medical device and healthcare industries. One of the Company's investments is in an unrealized loss position of $7.3 million, and the Company has evaluated the near-term prospects of this investment in relation to the severity and duration of the unrealized loss. The near-term prospects since the initial investment have not changed significantly and the unrealized losses have been deemed to be of a short-term nature. Based on that evaluation and the Company's ability and intent to hold this investment to full recovery of its carrying cost, the Company does not consider this investment to be other-than-temporarily impaired at June 27, 2015.
