Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We typically invest in a limited number of financial instruments, consisting principally of investments in money market accounts, certificates of deposit, and corporate and municipal bonds with a typical long-term debt rating of “A” or better by any nationally recognized statistical rating organization, denominated in U.S. dollars. All of our cash equivalents and investments are treated as “available-for-sale”. To quantify our interest rate risk exposure, we perform a sensitivity analysis based on hypothetical changes in interest rates. Based on investment positions as of December 31, 2024, a hypothetical 100 basis point increase in interest rates across all maturities would result in a $0.7 million decline in the fair market value of the portfolio. Such losses would only be realized if we sold the investments prior to maturity. For additional details, refer to Note 1 in Part II, Item 8 of this Amended 2024 Annual Report on Form 10-K/A.

Additionally, we have access to a $200.0 million line of credit borrowing facility which bears interest at SOFR plus 1.25 to 1.75% per year determined in accordance with a pricing grid based on our net leverage ratio and consolidated interest coverage ratio. Under the terms of the line of credit, available borrowings are reduced by outstanding letters of credit, which totaled $7.8 million at December 31, 2024. At December 31, 2024, there was no amount outstanding under the line of credit, and the available borrowing under the line of credit was $192.2 million. We have not borrowed any funds under the line of credit since its inception; however, should we need to do so in the future, such borrowings could be subject to adverse or favorable changes in the underlying interest rate.

There have been no other material changes in our primary risk exposures or management of risks since the prior year.

Exchange Rate Risk

Our results of operations and cash flows are subject to fluctuations due to changes in foreign currency exchange rates, in each case compared to the U.S. dollar, related to transactions by our foreign subsidiaries. The majority of our sales to international customers are transacted in foreign currencies and therefore are subject to exchange rate fluctuations on these transactions. The cost of our products to our customers increases when the U.S. dollar strengthens against their local currency, and we may have more sales and expenses denominated in foreign currencies in future years which could increase our foreign exchange rate risk. Additionally, intercompany sales to our non-U.S. dollar functional currency international subsidiaries are transacted in U.S. dollars which could increase our foreign exchange rate risk caused by foreign currency transaction gains and losses.

To date, we have not engaged in any currency hedging activities. However, we may enter into foreign currency forward and option contracts with financial institutions to protect against foreign exchange risks associated with certain existing assets and liabilities, certain firmly committed transactions, forecasted future cash flows and net investments in foreign subsidiaries. However, we may choose not to hedge certain foreign exchange exposures for a variety of reasons, including, but not limited to, the prohibitive economic cost of hedging particular exposures. As such, fluctuations in currency exchange rates could harm our business in the future.
