Restructuring Costs

In October 2007, we relocated our corporate headquarters to Mountain View, California. During fiscal year 2008, which ended on July 31, 2008 under our prior fiscal calendar, we recorded a restructuring charge of $2.2 million for the remaining facility space and leasehold improvements at our former corporate headquarters located in Fremont, California. At December 31, 2011 and December 31, 2010 all restructuring liabilities have been settled and no restructuring liabilities remain.

Below is a summary of the restructuring charges, net (in thousands):
