NOTE 5. CONCENTRATION OF RISK

Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of trade accounts receivable. We perform ongoing credit evaluations on the financial condition of our customers and generally do not require collateral. Our allowance for doubtful accounts balance was zero at March 31, 2018, and at December 31, 2017.

Revenues and accounts receivable from significant customers (customers with revenue or accounts receivable in excess of 10% of consolidated totals) are stated below as a percent of consolidated totals.
