INVESTMENTS IN MARKETABLE SECURITIES

The Company’s investments in marketable debt and equity securities as of September 30, 2013 and December 31, 2012 by security class and by level within the fair value hierarchy have been disclosed in Note 3 — Fair Value. The security classes are determined based on the nature and risk of a security and are consistent with how the Company manages, monitors and measures its marketable securities. As of September 30, 2013, all available-for-sale debt securities had stated maturities within one year.

The following table summarizes the pretax gains and losses related to available-for-sale and trading securities for the three and nine months ended September 30, 2013 and 2012. Gains and losses on the sale of investments are determined using the specific-identification method. For the three and nine months ended September 30, 2013 and 2012, there were no realized losses on the sale of available-for-sale securities and no other-than-temporary impairment of marketable securities recognized in earnings or other comprehensive income.
