EQUIPMENT IMPAIRMENT AND RESTRUCTURING
13. EQUIPMENT IMPAIRMENT AND RESTRUCTURING

In 2009, the Company recorded a $6.5 million charge for the impairment of certain excess semiconductor manufacturing equipment which was removed from service and was held for sale as of December 31, 2009. The $7.4 million net book value of the equipment held for sale was reduced to its estimated sales value of $910,000. Due to increased manufacturing output requirements which resulted from increased product demand in 2010, this equipment was placed back in service at $910,000 as of December 31, 2010.
