Debt Disclosure [Abstract]
Debt	Debt Credit Agreement On April 23, 2012, we entered into an Amendment to our $20.0 million Credit Agreement (the “Amendment”) with Wells Fargo Bank, National Association. The Amendment changes the Credit Agreement from a secured revolving credit facility to an unsecured revolving credit facility and extends the maturity date of the credit facility from July 1, 2012 to April 23, 2015. The amended credit facility contains an accordion feature that allows us to increase the amount of the line from $20.0 million to up to $50.0 million in total availability, subject to lender approval. The Amendment also decreases the amount of commitment fees, lowers the rate at which interest accrues and increases the financial flexibility with regard to our financial covenants.
