        Intangible assets consist of licensing and certification rights which are amortized over a defined number of units. The Company had non-cash purchases of other assets of $0, $0 and $100,000 in 2011, 2010 and 2009, respectively. No impairment charge was recorded in fiscal 2011, 2010 or 2009.

        Total intangible amortization expense was approximately $0.1 million, $0.1 million and $0.2 million for fiscal 2011, 2010 and 2009, respectively. Since the intangible assets are being amortized over a defined number of units, the future amortization expense over the next five years cannot be determined at this time.
