The Company’s business is exposed to risk resulting from fluctuations in interest rates on certain LIBOR-based variable rate debt. Increases in interest rates would increase interest expenses relating to the outstanding variable rate borrowings and increase the cost of debt. Fluctuations in interest rates can also lead to significant fluctuations in the fair value of the debt obligations.

On May 15, 2018, the Company entered into a four-year pay-fixed, receive floating (1-month LIBOR), interest rate swap arrangement with a notional amount of $400,000 for the period beginning June 1, 2018 and ending on June 1, 2022. Under the terms of the interest rate swap, the Company pays a fixed rate of 2.84% against a portion of its LIBOR-based debt and receives floating 1-month LIBOR during the swap period.

At inception, the Company designated the interest rate swap as a cash flow hedge and the fair value of the interest rate swap was zero. As of September 27, 2021, the fair value of the interest rate swap was recorded as a liability in the amount of $7,372 and included as a component of other current liabilities. The change in the fair value of the interest rate swap is recorded as a component of accumulated other comprehensive loss, net of tax. No ineffectiveness was recognized for the quarter and three quarters ended September 27, 2021 and September 28, 2020. The interest rate swap increased interest expense by $2,775 and $2,707 for the quarters ended September 27, 2021 and September 28, 2020, respectively, and $8,278 and $6,224 for the three quarters ended September 27, 2021 and September 28, 2020, respectively.

The Company enters into foreign currency forward contracts to mitigate the impact of changes in foreign currency exchange rates and to reduce the volatility of purchases and other obligations generated in currencies other than its functional currencies. The Company’s foreign subsidiaries may at times purchase forward exchange contracts to manage their foreign currency risks in relation to certain purchases of machinery denominated in foreign currencies other than the Company’s functional currencies. The notional amount of the foreign exchange contracts as of September 27, 2021 and December 28, 2020 was approximately $1,245 (Japanese Yen (JPY) 132.3 million) and $1,181 (JPY 125.0 million), respectively. The Company has designated certain of these foreign exchange contracts as cash flow hedges.

The Company uses various raw materials in the manufacturing of PCBs. In particular, the Company has been experiencing increasing prices and lead times of copper clad laminates (CCLs), a key raw material for the manufacture of PCBs. CCLs are made from epoxy resin, glass cloth and copper foil, all of which are seeing limited supply and resulting increased prices. The Company only buys a small amount of copper directly. However, copper is a major driver of laminate cost. As such, the Company enters into commodity contracts to hedge copper as a proxy for hedging laminate. As of September 27, 2021, the Company has commodity contracts with a notional quantity of 0.5 metric tonnes each for the periods (i) beginning September 28, 2021 and ending on December 30, 2021, (ii) beginning January 4, 2022 and ending on March 31, 2022, and (iii) beginning April 5, 2022 and ending on June 29, 2022, and 0.6 metric tonnes for the period beginning June 30, 2022 and ending on October 3, 2022. As of September 27, 2021, the fair value of the commodity contracts was recorded as a liability in the amount of $65 and included as a component of other current liabilities. The changes in the fair value of these commodity contracts are recorded in cost of goods sold in the consolidated

condensed statements of operations. The commodity contracts increased cost of goods sold by $164 and $65 for the quarter and three quarters ended September 27, 2021, respectively. These commodity contracts are not designated as accounting hedges.
