INVESTMENTS

Investments at March 31, 2015 and December 31, 2014 consist of auction-rate securities. During the three months ended March 31, 2014, the Company sold its investment in a corporate equity security, which resulted in a realized gain of $0.4 million recorded under interest and other income, net in the Condensed Consolidated Statements of Operations.

For the three months endedMarch 31, 2015, auctions for the Company's sole auction-rate security continued to fail and as a result this security continues to be illiquid. The Company concluded that the remaining 1.0 million (adjusted cost) of auction-rate security is unlikely to be liquidated within the next twelve months and classified this security as a long-term investment, which is included in other assets in the Condensed Consolidated Balance Sheets. This auction-rate security had a contractual maturity greater than 10 years and totaled $1.0 million (at adjusted cost) as of March 31, 2015.
