MARKETABLE SECURITIES

NOTE 3. MARKETABLE SECURITIES

Our portfolio of marketable securities was comprised of debt securities that were classified as trading securities. Our marketable securities consisted of investments in mortgage-backed securities issued by the Government National Mortgage Association (“GNMA securities”). We reported our trading securities at fair value, using prices provided by independent market participants that were based on observable inputs using market-based valuation techniques (Level 2 of the fair value hierarchy-see Note 4). On August 20, 2012, we sold all of our outstanding GNMA securities with a realized loss of $0.7 million for the year ended December 31, 2012. For the three months ended March 31, 2012, gains and losses resulting from the mark-to-market of these securities were recognized as unrealized gains in income. Unrealized gain in our statement of income for the three months ended March 31, 2012 was $0.2 million and is included in other income (expense), net on the accompanying consolidated statement of income.
