Business and Credit Risk Concentration

(8) Business and Credit Risk Concentration

A substantial portion of our revenue has been generated under contracts with the U.S. Government. During the three months ended September 30, 2011 and 2010, approximately 68% and 61%, respectively, of our revenues were generated under U.S. Government contracts. Accounts receivable totaled $1.4 million at September 30, 2011, of which 77% was attributable to the U.S. Government.

The Company maintains funds in bank accounts that may exceed the limit insured by the Federal Deposit Insurance Corporation, or “FDIC.” In October 2008, the FDIC increased its insurance to $250,000 per depositor, and to an unlimited amount for non-interest bearing accounts. The risk of loss attributable to these uninsured balances is mitigated by depositing funds in what we believe to be high credit quality financial institutions. The Company has not experienced any losses in such accounts.
