Item 3. Quantitative and Qualitative Disclosures about Market Risk
Interest Rate Sensitivity
We had cash and cash equivalents of $368.7 million and $149.7 million as of March 31, 2026 and June 30, 2025, 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.
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 Taiwanese 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 $2.9 million for the three months ended March 31, 2026.
We have certain bank accounts outside the U.S., which 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 Taiwanese Dollar. A 10% appreciation or depreciation in the value of the U.S. dollar relative to the other currencies in which bank accounts as of March 31, 2026 are denominated would result in a charge or benefit to our income before income taxes of approximately $5.8 million for the three months ended March 31, 2026.
