Notes To Financial Statements
Operating Leases of Lessee Disclosure [Table Text Block]	(9) LEASEHOLD IMPROVEMENTS AND DEFERRED RENT We record tenant improvements made to our leased facilities based on the amount of the total cost to construct the improvements regardless of whether a portion of that cost was paid through an allowance provided by the facility's landlord. The amount of the allowance, if any, is recorded as deferred rent. We amortize deferred rent on a straight-line basis over the lease term and record the amortization as a reduction of rent expense. During 2005, we recorded $854 of additions to our leasehold improvements which were paid for on our behalf by the landlord of our facility in San Jose, California. We occupied this facility during the first quarter of 2005. We also recorded this amount as deferred rent. Amortization of deferred rent for the years ended December 31, 2011 and 2010 was $118 and $118, respectively. The current portion of deferred rent is included in Other Current Liabilities on our balance sheet.
