All cash equivalents are managed within established guidelines which limit the amount which may be invested with one issuer. A significant percentage of our accounts receivable have been, and will continue to be, concentrated among a relatively small number of automotive retailers and warehouse distributors in the United States. Our five largest customers accounted for 85% of net accounts receivable as of December 30, 2017 and 87% of net accounts receivable as of December 31, 2016. We continually monitor the credit terms and credit limits to these and other customers. In fiscal 2017, approximately 71% of our products were purchased from suppliers located in a variety of foreign countries, with the largest portion coming from China.</font></p></div> | |
