Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risks, which include significant deterioration of the U.S. and foreign markets, changes in U.S. interest rates, foreign currency exchange rate fluctuations, and the effects of economic uncertainty which may affect the prices we pay our vendors in the foreign countries in which we do business. We do not engage in financial transactions for trading or speculative purposes.

Interest Rate Risk

Our revolver has a variable interest rate which, when drawn upon, subjects us to risks associated with changes in that interest rate. During the third quarter of fiscal 2021, we had no borrowings under the revolver.

In addition, we have fixed and variable income investments consisting of short-term investments classified as cash and cash equivalents, which are also affected by changes in market interest rates. As of October 31, 2021, our investments, made primarily in interest-bearing demand deposit accounts and money market funds, are stated at cost and approximate their fair values.

Foreign Currency Risks

We purchase the majority of our inventory from vendors outside of the U.S. in transactions that are denominated in U.S. dollars and, as such, any foreign currency impact related to our international purchase transactions was not significant to us during the third quarter of fiscal 2021 or the third quarter of fiscal 2020. Since we pay for the majority of our international purchases in U.S. dollars, however, a decline in the U.S. dollar relative to other foreign currencies would subject us to risks associated with increased purchasing costs from our vendors in their effort to offset any lost profits associated with any currency devaluation. We cannot predict with certainty the effect these increased costs may have on our financial statements or results of operations.

In addition, our businesses in Canada, Australia and the United Kingdom, and our operations throughout Asia and Europe, expose us to market risk associated with foreign currency exchange rate fluctuations. Substantially all of our purchases and sales are denominated in U.S. dollars, which limits our exposure to this risk. However, some of our foreign operations have a functional currency other than the U.S. dollar. While the impact of foreign currency exchange rate fluctuations was not material to us in the third quarter of fiscal 2021 or the third quarter of fiscal 2020, we have continued to see volatility in the exchange rates in the countries in which we do business. As we continue to expand globally, the foreign currency exchange risk related to our foreign operations may increase. To mitigate this risk, we hedge a portion of our foreign currency exposure with foreign currency forward contracts in accordance with our risk management policies (see Note H to our Condensed Consolidated Financial Statements).
