Risks and Uncertainties [Abstract] |
Concentration Risk Disclosure [Text Block] | Financial Instruments and Concentration of Credit RiskFinancial instruments that potentially subject the Company to credit risk consist primarily of cash, cash equivalents, trade accounts receivable, foreign currency forward contracts and interest rate swap agreements. 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 and interest rate swaps 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.Nokia represented 10% or more of the Company's net sales in 2023 and 2021. Nokia and Motorola each represented 10% or more of the Company’s net sales in 2022. No customer represented 10% or more of the Company’s gross accounts receivable as of September 30, 2023 and Motorola represented 10% or more of the Company’s gross accounts receivable as of October 1, 2022.
