2. Investments

Management determines the appropriate classification of securities at the time of purchase and reevaluates such designation as of each balance sheet date. Currently, we classify all securities as available-for-sale. We carry available-for-sale securities at fair value, with temporary unrealized gains and losses, net of tax, reported in accumulated other comprehensive income, a component of stockholders’ investment. The amortized cost of debt securities in this category reflects amortization of premiums and accretion of discounts to maturity computed under the effective interest method. We include this amortization in the caption “Net investment income and other” within the Condensed Consolidated Statement of Operations and Comprehensive Loss. We also include in “Net investment income and other” realized gains and losses and declines in value determined to be other-than-temporary. We base the cost of securities sold upon the specific identification method. We include interest and dividends on securities classified as available-for-sale in “Net investment income and other.”

We held certificates of deposit with an adjusted cost basis and fair value of $2.0 million at March 31, 2014 and December 31, 2013. We did not recognize any realized or unrealized gains or losses on the sale of investment securities during the three months ended March 31, 2014 and 2013. We realized no gains or losses on the sale of investment securities for the three months ended March 31, 2014.
