Concentration of Credit Risks
Financial instruments which potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents and trade receivables. The Company places its cash and cash equivalents with high credit quality financial institutions. Concentrations of credit risk with respect to sales and trade receivables are limited due to the large number of customers comprising the Company's customer base and their dispersion across geographic areas. The Company performs periodic credit evaluations of its customers' financial condition and generally does not require collateral.
For the year ended December 30, 2017, the largest three customers accounted for 45.8% of sales and 27.0% of the year-end accounts receivable balance. For the year ended December 31, 2016, the largest three customers accounted for 46.1% of sales and 34.3% of the year-end accounts receivable balance. No other customer accounted for more than 5.0% of the Company's total sales in 2017, 2016, or 2015. In each of the years ended December 30, 2017, December 31, 2016, and December 31, 2015, the Company derived over 10% of its total revenues from two separate customers which operated in the following segments: United States, Canada, and Mexico.
