CONCENTRATION OF RISK [Abstract]
CONCENTRATION OF RISK	15. Concentration of risk Credit Risk Credit risk is the potential financial loss resulting from the failure of a customer or counterparty to settle its financial and contractual obligations to the Company, as and when they become due. The primary credit risk for the Company is its accounts receivable due from customers. The Company has established credit limits for customers and monitors their balances to mitigate the risk of loss. As of December 29, 2018 and December 30, 2017, there were no significant concentrations of credit risk. No single customer represented more than 10% of the Company's net accounts receivable as of December 29, 2018 or at December 30, 2017. The maximum exposure to credit risk is primarily represented by the carrying amount of the Company's accounts receivable. Interest Rate Risk The Company's exposure to the risk of changes in market interest rates relates primarily to the Company's debt, which bears interest at variable rates based on the LIBOR rate plus a margin spread of 1.75% to 2.50%. The Company has an interest rate swap with a notional amount of $14,337,500 on December 29, 2018 to convert a portion of its 2017 Term Loan from variable to fixed rates. The valuation of this swap is determined using the three month LIBOR rate index and mitigates the Company's exposure to interest rate risk. Additionally, interest rates on the Company's debt are susceptible to changes to the method that LIBOR rates are determined and to the potential phasing out of LIBOR after 2021. More information regarding the potential phasing out of LIBOR is discussed in greater detail under Note 7 to Consolidated Financial Statements. Currency Exchange Rate Risk The Company's currency exposure is concentrated in the Canadian dollar, Mexican peso, New Taiwan dollar, Chinese RMB and the Hong Kong dollar. Because of the Company's limited exposure to any single foreign market, any exchange gains or losses have not been material and are not expected to be material in the future. As a result, the Company does not attempt to mitigate its foreign currency exposure through the acquisition of any speculative or leveraged financial instruments.
