Marketable Securities – Unrealized Losses

The Company owned 47 available-for-sale securities as of June 30, 2015. Of these 47 securities, 33 had combined unrealized losses of less than $0.1 million as of June 30, 2015. The Company did not have any investments in a loss position for greater than 12 months as of June 30, 2015. The Company has evaluated its marketable securities and has determined that none of these investments has an other-than-temporary impairment, as it has no intent to sell securities with unrealized losses and it is not more likely than not that the Company will be required to sell any securities with unrealized losses, given the Company’s current and anticipated financial position.
