Risks and Uncertainties [Abstract]
Concentration Risk Disclosure [Text Block]	Financial Instruments and Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk consist primarily of cash, cash equivalents, trade accounts receivable and foreign currency forward contracts. The carrying value of assets such as cash, cash equivalents and accounts receivable is expected to approximate fair value due to the short duration of the assets. The Company maintains its cash and cash equivalents with recognized financial institutions that management believes to be of high credit quality. One of the Company's most significant credit risks is the ultimate realization of accounts receivable. This risk is mitigated by ongoing credit evaluations of, and frequent contact with, the Company's customers, especially its most significant customers, thus enabling it to monitor changes in business operations and respond accordingly. The Company generally does not require collateral for sales on credit. The Company considers these concentrations of credit risks when estimating its allowance for doubtful accounts. Foreign currency forward contracts are maintained with high quality counterparties to reduce the Company's credit risk and are recorded on the Company's balance sheets at fair value. Two customers represented more than 10% of the Company's net sales in 2017, one customer represented more than 10% of the Company's net sales in 2016 and no customer represented more than 10% of the Company's net sales in 2015. One customer represented 10% or more of the Company's gross accounts receivable as of September 30, 2017 and October 1, 2016.
