CONCENTRATIONS

The Company has identified certain concentrations that are present in their business operations. The Company's revenue from ethanol sales is derived from a single customer under an ethanol marketing agreement described in Note 12. Sales under that agreement account for approximately 80%, 83%, and 86% of the Company's revenues, net of derivative activity, during fiscal 2012, 2011 and 2010, respectively. Accordingly, 79% and 81% of the Company's receivables are regularly due from that same customer at October 31, 2012 and 2011, respectively.
