INVESTMENTS IN MARKETABLE SECURITIES

The Company’s investments in marketable debt and equity securities as of December 31, 2014 and 2013 by security class and by level within the fair value hierarchy have been disclosed in Note 4—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 December 31, 2014, $676 million of available-for-sale ("AFS") debt securities had stated maturities within one year and $33 million had stated maturities between one and three years. Gains and losses on the sale of investments are determined using the specific-identification method. Pretax gains and losses related to AFS and trading securities are generally immaterial for disclosure purposes. For the years ended December 31, 2014, 2013, and 2012, there were no realized losses on the sale of AFS securities and no other-than-temporary impairment of marketable securities recognized in earnings or other comprehensive income. The following table summarizes the gross proceeds from sale of AFS securities for the years ended December 31, 2014, 2013, and 2012:
