Fair Value Disclosures [Abstract]  
Fair value of financial instruments Fair value of financial instruments
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A fair value hierarchy is established, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs for the valuation of an asset or liability as of the measurement date. The three levels of inputs that may be used to measure fair value are defined as follows:
Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.
Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for assets or liabilities, either directly or indirectly. If the assets or liabilities have a specified (contractual) term, Level 2 inputs must be observable for substantially the full term of assets or liabilities.
Level 3 inputs are unobservable inputs for assets or liabilities, which require the reporting entity to develop its own valuation techniques and assumptions.
The Company utilizes the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.
The following table provides details of the financial instruments measured at fair value on a recurring basis, including:

Derivative Financial Instruments
The Company utilizes derivative financial instruments to hedge (i) foreign exchange risk associated with certain foreign currency denominated assets and liabilities and other foreign currency transactions, and (ii) interest rate risk associated with its long-term debt.
The Company minimizes the credit risk associated with its derivative instruments by limiting the exposure to any single counterparty and by entering into derivative instruments only with counterparties that meet the Company’s minimum credit quality standard.
Foreign Currency Forward and Option Contracts
As a result of foreign currency rate fluctuations, the U.S. dollar equivalent values of the Company’s foreign currency denominated assets and liabilities fluctuate. The Company uses foreign currency forward and option contracts to manage the foreign exchange risk associated with a portion of its foreign currency denominated assets and liabilities and other foreign currency transactions. The Company enters into foreign currency forward and option contracts to hedge
fluctuations in the U.S. dollar value of forecasted transactions denominated in Thai baht and Canadian dollars with counterparties that meet the Company’s minimum credit quality standard.
The Company may enter into foreign currency forward contracts with maturities of up to 12 months to hedge fluctuations in the U.S. dollar value of forecasted transactions denominated in Thai baht, including inventory purchases, payroll and other operating expenses. The Company considers these forward contracts as dual-purpose hedges, that hedge both the foreign exchange fluctuation (i) from inception through the forecasted expenditure, and (ii) any subsequent revaluation of the account payable or accrual. The Company may designate the forward contracts that hedge the foreign exchange fluctuation from inception through the forecasted expenditure as cash flow hedges. The gain or loss on a derivative instrument designated and qualified as a cash flow hedging instrument is recorded as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings. The reclassified amounts are presented in the same income statement line item as the earnings effect of the hedged item. Once the forecasted transactions are recorded, the Company will discontinue the hedging relationship by de-designating the derivative instrument and recording subsequent changes in fair value through contract maturity to foreign exchange gain (loss), net in the consolidated statements of operations and comprehensive income as a natural hedge against the Thai baht denominated assets and liabilities.
The Company may also enter into non-designated foreign currency forward and option contracts to provide an offset to the re-measurement of foreign currency denominated assets and liabilities and to hedge certain forecasted exposures. Changes in the fair value of these non-designated derivatives are recorded through foreign exchange gain (loss), net in the consolidated statements of operations and comprehensive income.
As of June 27, 2025, the Company had 165 outstanding U.S. dollar foreign currency forward contracts against Thai baht with an aggregate notional amount of $165.0 million and with maturity dates ranging from July 2025 through December 2025, and one foreign currency contract with a notional amount of 0.5 million Canadian dollars and with a maturity date in September 2025.
As of June 28, 2024, the Company had 135 outstanding U.S. dollar foreign currency forward contracts against Thai baht with an aggregate notional amount of $135.0 million and with maturity dates ranging from July 2024 through January 2025, and one foreign currency contract with a notional amount of 0.4 million Canadian dollars and with a maturity date in September 2024.
As of June 27, 2025, the hedging relationship over foreign currency forward contracts which were designated for hedge accounting had been tested to be highly effective based on the performance of retrospective and prospective regression testing. As of June 27, 2025, the amount in AOCI that is expected to be reclassified into earnings within 12 months as gain was $1.5 million.
During the year ended June 27, 2025 and June 28, 2024, the Company included an unrealized gain of $1.9 million and $0.7 million, respectively, from changes in fair value of foreign currency forward and option contracts which were not designated for hedge accounting in earnings as foreign exchange gain (loss), net in the consolidated statements of operations and comprehensive income.
