Impairment of Long Lived Assets

Note 7 — Impairment of Long Lived Assets

In an effort to reduce ongoing operating costs and improve our organizational structure, efficiency and productivity, on March 20, 2012, we announced a plan to consolidate our U.S.-based research activities at our existing San Francisco location and to cease the use of and sell one of our buildings located in Huntsville, Alabama that was dedicated to research activities. As a result, we performed a preliminary analysis of the fair value of the land, building and related improvements based primarily on market data, concluded that the combined carrying value of the land and building exceeded fair value and recorded an impairment loss of $1.7 million. Until we have disposed of these assets, we will update our analysis of their fair value on a regular basis and such updates could result in further impairment charges in future periods.
