Intangible assets, net of accumulated amortization of $441,637 and $391,829 at September 30, 2012 and September 30, 2011	$	158,600	$	208,408

        Intangible assets consist of licensing and certification rights which are amortized over a defined number of units. The Company had no non-cash purchases of other assets in 2012, 2011 and 2010. No impairment charges were recorded in fiscal 2012, 2011 or 2010.

        Total intangible amortization expense was approximately $0.1 million, $0.1 million and $0.1 million for fiscal 2012, 2011 and 2010, respectively. Since the intangible assets are being amortized over a defined number of units, the timing of future amortization expense is not determinable.
