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 December 31, 2018, the Company had approximately $794,000 of cash not insured. 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.
