There are no investments in current available-for-sale marketable debt securities that have been in a continuous unrealized loss position for longer than twelve months as of December 31, 2016. The gross unrealized losses on the marketable debt securities relate primarily to changes in interest rates. The Company does not consider the gross unrealized losses to be other-than-temporary because the Company does not intend to sell the marketable debt securities that generated the gross unrealized losses at December 31, 2016, and it is not more likely than not that the Company will be required to sell these securities before recovery of their amortized costs bases, which may be maturity.
