The Company places its cash equivalents with high credit quality financial institutions. As of December 29, 2018, the Company’s cash and cash equivalents were invested in investment-grade, highly-liquid U.S. government agency corporate money market accounts.</div></div><div style="font-size:10pt; color:#000000; font-family:'times new roman'; font-style:normal; font-variant-ligatures:normal; font-variant-caps:normal; font-weight:400; letter-spacing:normal; orphans:2; text-align:start; text-indent:0px; text-transform:none; white-space:normal; widows:2; word-spacing:0px; -webkit-text-stroke-width:0px; text-decoration-style:initial; text-decoration-color:initial; margin-top:12pt; margin-bottom:0pt"><div style="color: rgb(0, 0, 0); letter-spacing: 0px; top: 0px;;display:inline;">The Company sells primarily to a network of independent wholesalers in the United States and to a network of foreign wholesalers, importers or other agencies (collectively referred to as “Distributors”). In 2018, 2017 and 2016, sales to foreign Distributors were approximately 4% of total sales. Receivables arising from these sales are not collateralized; however, credit risk is minimized as a result of the large and diverse nature of the Company’s customer base. There were no individual customer accounts receivable balances outstanding at December 29, 2018 and December 30, 2017 that were in excess of 10% of the gross accounts receivable balance on those dates. No individual customers represented more than 10% of the Company’s revenues during fiscal years 2018, 2017, or 2016.</div></div><table border="0" style="width:100%; table-layout:fixed;" cellspacing="0" cellpadding="0"><tr><td></td></tr></table>
