Debt Disclosure [Abstract]
State of Oregon Loan	State of Oregon Loan In the first quarter of Fiscal 2012, we received a loan from the State of Oregon for $0.5 million for the purpose of facility renovations. The loan bore interest at 5% per annum and contained provisions relating to forgiveness if we met certain requirements. On April 3, 2013, the loan was forgiven in full. The balance of this loan was recorded as an offset to leasehold improvements and will be amortized as an offset to depreciation expense over the life of the lease, which expires in 2023. See Note 13.
