Subsequent Event
Subsequent Event	Note 16. Subsequent Event In October 2011, we entered into a lease agreement for approximately 100,000 square feet of office space. Pursuant to the lease agreement, the landlord will construct a single, three-story building of rentable space located at 590 Middlefield Road in Mountain View, California which we will subsequently lease. The term of the lease agreement is for a period of 120 months, expected to commence November 2012, with a base lease commitment of approximately $40.0 million. We have two options to extend the term of the lease agreement at market rates; both extensions are for an additional 60 month term.
