NOTE 5. CONCENTRATION OF CREDIT RISK

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents, short-term investments and accounts receivable, including receivables from major customers.

The Company has financial institutions for banking operations that hold 10% or more of the Company’s cash and cash equivalents. As of September 30, 2018, three of the Company's financial institutions held 57%, 31% and 12% of the Company’s cash and cash equivalents, respectively. As of December 31, 2017, two of the Company's financial institutions held 82% and 12% of the Company’s cash and cash equivalents, respectively.

The Company grants credit to domestic and international clients in various industries. Exposure to losses on accounts receivable is principally dependent on each client's financial position. The Company had two customers that accounted for 18% and 13% of the Company’s net accounts receivable balance as of September 30, 2018, and one customer that accounted for 24% of the Company's net accounts receivable balance as of December 31, 2017.
