SHORT-TERM INVESTMENTS

Short-term investments at December 31, 2011 were comprised of an equity investment in the common stock of a technology company, classified as available-for-sale, with a cost basis of $8,427,000, unrealized losses of $1,830,000 included in other comprehensive loss in the consolidated statement of stockholder's equity as of December 31, 2011, and a recorded basis of $6,597,000. For the periods presented, equity investments in common stock are reported at fair value on a recurring basis using significant observable inputs (Level 1). Unrealized loss positions related to equity investments have existed for less than twelve months, and are due to market price movements. Acacia's management does not believe any remaining unrealized losses represent other-than-temporary impairments based on its evaluation of available evidence as of December 31, 2011.
