The unrealized loss of $0.3 million in the table above relates to fifty-eight securities with an aggregate fair value of $123.2 million. 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, 2014. All of the Company’s marketable debt securities are rated investment grade. The gross unrealized losses on the marketable debt securities relate principally to changes in interest rates. Because the Company does not intend to sell any marketable debt securities and it is not more likely than not that the Company will be required to sell any marketable debt securities before recovery of their amortized cost bases, which may be maturity, the Company does not consider any of its marketable debt securities to be other-than-temporarily impaired at December 31, 2014. At December 31, 2013, current available-for-sale marketable securities are as follows:
| Amortized Cost |  | Gross Unrealized Gains |  | Gross Unrealized Losses |  | Estimated Fair Value

Total marketable securities | $ | 1,220 |  |  | $ | 4,784 |  |  | $ | — |  |  | $ | 6,004 |
