Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Exchange Risk

From time to time, we use foreign exchange forward contracts to hedge a portion of our exposures to changes in currency exchange rates, which result from our global operating and financing activities. We do not use derivative financial instruments for trading or speculative purposes. Neither gains and losses from foreign currency transactions nor foreign exchange forward contracts were significant for any period presented in the consolidated financial statements included in this Form 10-K. We did not have any outstanding foreign exchange forward contracts as of October 29, 2023 or October 30, 2022.

Interest Rate Risk

Changes in interest rates affect the fair value of our outstanding debt. As of October 29, 2023 and October 30, 2022, we had $40.8 billion and $41.2 billion in principal amount of debt outstanding, and the estimated aggregate fair value of debt was $33.2 billion and $33.0 billion, respectively. As of October 29, 2023 and October 30, 2022, a hypothetical 50 basis points increase or decrease in market interest rates would change the fair value of debt by a decrease or increase of approximately $1.4 billion and $1.6 billion, respectively. However, this hypothetical change in interest rates would not impact the interest expense on our debt as we only had fixed rate senior notes outstanding. To hedge variability of cash flows due to changes in the benchmark interest rate of anticipated future debt issuances, we have entered, and in the future may enter, into treasury rate lock contracts.
