        On November 29, 2011, AMR Corporation, the parent company of American Airlines, Inc. and certain of its other U.S.-based subsidiaries filed voluntary petitions for Chapter 11 reorganization in the U.S. Bankruptcy Court for the Southern District of New York (the "bankruptcy"). The Company's revenues from American Airlines, Inc. accounted for 8%, 8% and 24% total revenue for the fiscal years 2011, 2010 and 2009, respectively. As of November 29, 2011, the Company had outstanding accounts receivable of $760,000 from American Airlines, Inc. for sales made after September 30, 2011.

        As of September 30, 2011, the Company had accounts receivable of $667,000 from American Airlines, Inc., all of which were collected in the normal course of business prior to November 29, 2011. Under the U.S. bankruptcy laws, debtors have the right to avoid certain payments made during the 90 days preceding the filing of the bankruptcy petition. No such avoidance action has been asserted or filed, and the Company believes that it would have valid defenses against any such action. In the 90 days preceding the filing of the Bankruptcy petition, the Company received $828,000 from American Airlines, Inc. in the ordinary course of business, which includes collections of $161,000 related to revenue recognized by the Company from August 2011 through September 30, 2011.
