Item 3. Quantitative and Qualitative Disclosures about Market Risk
Interest Rate Sensitivity
We had cash and cash equivalents of $97.6 million and $114.8 million as of December 31, 2023 and June 30, 2023, respectively. Cash and cash equivalents includes securities that have a maturity of three months or less at the date of purchase. These amounts were held primarily in cash deposit accounts in U.S. dollars. The fair value of our cash and cash equivalents would not be significantly affected by either a 10% increase or decrease in interest rates due mainly to the short-term nature of these instruments.
Debt
We are exposed to interest rates risks primarily through borrowing under our credit facility. Interest on our borrowings is based on variable rates. Based on a sensitivity analysis, as of December 31, 2023, an instantaneous and sustained 200-basis-point increase in interest rates affecting our floating rate debt obligations, and assuming that we take no counteractive measures, would result in an incremental charge to our income before income taxes of approximately $19.9 million over the next twelve months.
Foreign Currency Risk
Certain of our sales, labor and other costs included in costs of revenue and operating expenses are denominated in the currencies of the countries in which our operations are located and may be subject to fluctuations due to changes in foreign currency exchange rates, particularly changes in the Chinese Yuan, Euro, and Taiwan Dollar. A 10% appreciation or depreciation in the value of the U.S. dollar relative to the other currencies in which our revenue and expenses are denominated would result in a charge or benefit to our income before income taxes of approximately $1.0 million for the three months ended December 31, 2023.
