Interest Rate Risk Our exposure to interest rate risk primarily relates to the interest income generated by excess cash invested in liquid investments with original maturities of three months or less and term deposits with maturities of greater than three months and less than a year. We have not used any derivative financial instruments to manage our interest risk exposure. Interest-earning instruments carry a degree of interest rate risk. We have not been exposed, nor do we anticipate being exposed, to material risks due to changes in interest rates. However, our future interest income may be lower than expected due to changes in market interest rates. A hypothetical one percentage point decrease in interest rates would have resulted in a decrease of approximately US$51.4 million in our interest income for the year ended May 31, 2025. Foreign Exchange Risk The conversion of Renminbi into other currencies, including U.S. dollars, is based on rates set by the People’s Bank of China. The Renminbi has fluctuated against other currencies, at times significantly and unpredictably. The value of Renminbi against other currencies is affected by changes in China’s political and economic conditions and by China’s foreign exchange policies, among other things. It is difficult to predict how market forces or government policies may impact the exchange rate between Renminbi and other currencies in the future.
