Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Foreign Currency Exchange Risk

Our results of operations and cash flows are subject to fluctuations due to changes in foreign currency exchange rates, particularly changes in the British Pound Sterling, Euro, Japanese Yen, and Chinese Yuan, and may be adversely affected in the future due to changes in foreign currency exchange rates. We continue to experience foreign currency fluctuations primarily due to the periodic re-measurement of our foreign currency monetary account balances that are denominated in currencies other than the functional currency of the entities in which they are recorded. Changes in exchange rates may negatively affect our revenues and other operating results as expressed in U.S. dollars. For the fiscal years ended January 31, 2021, 2020 and 2019, we had foreign currency gains of $2 million, losses of $1 million, and losses of $2 million, respectively.

We have experienced and will continue to experience fluctuations in our net income as a result of gains or losses related to revaluing certain current asset and current liability balances that are denominated in currencies other than the functional currency of the entities in which they are recorded. We engage in the hedging of our foreign currency transactions as described in note 8 of the notes to our consolidated financial statements and may, in the future, hedge selected significant transactions or net monetary exposure positions denominated in currencies other than the U.S. dollar.

Interest Rate Sensitivity

We had cash, cash equivalents and short-term investments totaling $1,664 million as of January 31, 2021. This amount was held primarily in demand deposit accounts, money market funds, U.S. treasury securities and agency obligations, corporate notes and bonds, asset-backed securities, commercial paper, foreign government bonds, and agency mortgage-backed securities. The cash and cash equivalents are held for working capital purposes. We do not enter into investments for trading or speculative purposes.

Our cash equivalents and our portfolio of marketable securities are subject to market risk due to changes in interest rates, which could affect our results of operations. Fixed rate securities may have their market value adversely affected due to a rise in interest rates, while floating rate securities may produce less income than expected if interest rates fall. Due in part to these factors, our future investment income may fluctuate due to changes in interest rates or we may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in interest rates. However, because we classify our marketable securities as “available for sale,” no gains or losses are recognized due to changes in interest rates unless such securities are sold prior to maturity or declines in fair value are determined to be other-than-temporary. Our fixed-income portfolio is subject to interest rate risk.

An immediate increase of 100-basis points in interest rates would have resulted in a $9 million market value reduction in our investment portfolio as of January 31, 2021. An immediate decrease of 100-basis points in interest rates would have increased the market value by $3 million as of January 31, 2021. This estimate is based on a sensitivity model that measures market value changes when changes in interest rates occur. Fluctuations in the value of our investment securities caused by a change in interest rates (gains or losses on the carrying value) are recorded in other comprehensive income, and are realized only if we sell the underlying securities.
