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 six months ended December 31, 2012 and 2011, approximately 58% and 63%, respectively, of our revenues were generated under U.S. Government contracts. Accounts receivable totaled $3.7 million at December 31, 2012, of which 15% 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.
