NOTE 3. 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 June 30, 2019, two of the Company's financial institutions held 55% and 41% of the Company’s cash and cash equivalents, respectively. As of December 31, 2018, two of the Company's financial institutions held 46% and 43% of the Company’s cash and cash equivalents, respectively.

The Company grants credit to domestic and international customers. Exposure to losses on accounts receivable is principally dependent on each client's financial position. The Company had one customer that accounted for 19% of the Company’s net accounts receivable balance as of June 30, 2019, and one customer that accounted for 10% of the Company's net accounts receivable balance as of December 31, 2018.

Customers who represented 10% or more of the Company’s total revenue for the three and six months ended June 30, 2019 and 2018 were as follows:
