Impairment of Long Lived Assets	9 Months Ended
Sep. 30, 2012
Impairment of Long Lived Assets	Note 8 — Impairment of Long Lived Assets In an effort to reduce ongoing operating costs and improve our organizational structure, efficiency and productivity, in March 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 available market data. Based upon this analysis, we concluded that the combined carrying value of the land and building exceeded fair value and we recorded an impairment loss of $1.7 million in March 2012. No further impairment losses were recorded in the quarters ended June 30, 2012 and September 30, 2012, however, until we dispose 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.
