The carrying amounts reported in the condensed consolidated balance sheet approximate the fair value based on quoted market prices or alternative pricing sources and models utilizing market observable inputs. As of June 30, 2015, the Company does not consider any of its marketable securities to be other than temporarily impaired. During the six months ended June 30, 2015 and 2014, the Company did not reclassify any items out of accumulated other comprehensive income to net income. All investments in marketable securities are classified as a current asset on the balance sheet because the underlying securities mature within one year from the balance sheet date.
