SIGNIFICANT CUSTOMERS AND EXPORT SALES [Text Block] | SIGNIFICANT CUSTOMERS AND GEOGRAPHIC NET REVENUES: Customer Concentration The Company's top ten customers accounted for approximately 54%, 60% and 61% in 2017, 2016 and 2015, respectively. A significant portion of these revenues are attributable to sales of the Company’s products to distributors of electronic components. These distributors sell the Company’s products to a broad, diverse range of end users, including OEMs and merchant power supply manufacturers. Sales to distributors in 2017, 2016 and 2015 were $330.9 million, $292.6 million and $261.4 million, respectively. Direct sales to OEMs and power-supply manufacturers accounted for the remainder. The following customers, distributors of the Company’s products, each accounted for 10% or more of total net revenues:
