        There were no debt securities that had been in an unrealized loss position for more than 12 months as of December 31, 2014. There were 34 debt securities in an unrealized loss position for less than 12 months at December 31, 2014. The aggregate unrealized loss on these securities as of December 31, 2014 was less than $34 thousand and the fair value was $68.9 million. As it was not more likely than not that the Company would be required to sell these securities before the recovery of their amortized cost basis, which may be maturity, the Company did not consider these investments to be other-than-temporarily impaired as of December 31, 2014.

        The contractual term to maturity of all marketable securities held by the Company as of December 31, 2014 is less than one year.
