21.    Business and Credit Concentration

Financial instruments

        Financial instruments which potentially subject us to credit risk consist primarily of cash and cash equivalents (the amounts of which may, at times, exceed Federal Deposit Insurance Corporation limits on insurable amounts), investments and trade accounts receivable. We mitigate our risk by investing in or through major financial institutions.

Customers

        We perform on-going credit evaluations of our customers and adjust credit limits based upon payment history and the customers' current creditworthiness, as determined by review of their current credit information. Customers' account activity is continuously monitored. As a result of this review process, we record bad debt expense, which is based upon historical experience as well as specific customer collection issues that have been identified, to adjust the carrying amount of the related receivable to its estimated realizable value. While such bad debt expenses historically have been within expectations and the allowances established, if the financial condition of one or more of our customers were to deteriorate, additional bad debt provisions may be required.

        One customer accounted for the following percentages of net sales for the fiscal years ended September 30:

 
  Wholesale/US Nutrition Segment
Net Sales
  Total Consolidated
Net Sales
 
 
  2013   2012   2011   2013   2012   2011  

Customer A

    21 %   23 %   25 %   13 %   14 %   15 %

        The loss of this customer, or any of our other major customers, would have a material adverse effect on our consolidated results of operations if we were unable to replace such customer(s).

        The following customers accounted for the following percentages of the Wholesale/US Nutrition segment's gross accounts receivable at fiscal years ended:

 
  2013   2012  

Customer A

    12 %   18 %

Customer B

    11 %   9 %

Suppliers

        During fiscal 2013, 2012 and 2011, no one supplier provided more than 10% of our raw material purchases. We do not believe that the loss of any single supplier would have a material adverse effect on our consolidated financial condition or results of operations.
