- CONCENTRATIONS
 
Credit Risk
 
Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of temporary cash investments and unsecured trade accounts receivable. The Company maintains cash balances at a financial institution in San Diego, California. Our cash balance at this institution is secured by the Federal Deposit Insurance Corporation up to $250,000. As of
September 30, 2016, cash totaled approximately $88,000, which consists of funds held in a non-interest bearing bank deposit account. The Company has not experienced any losses in such accounts. Management believes that the Company is not exposed to any significant credit risk with respect to its cash.
