Marketable Securities

Our marketable securities consist primarily of investments in preferred stock of $22.3 million and $22.2 million as of June 30, 2014 and December 31, 2013, respectively. We classify our marketable securities as available-for-sale and carry them at fair value with unrealized gains or losses classified as a component of accumulated other comprehensive income. There were no gains or losses recognized on sales of marketable securities for the three and six months ended June 30, 2014 and 2013.
