Item 3. Quantitative and Qualitative Disclosures About Market Risk

CURRENCY EXCHANGE RATE RISK

Due to the global nature of our operations, we are exposed to currency exchange rate changes, which may cause fluctuations in earnings and cash flows. Fluctuations in the currency exchange rates of currency exposures that are unhedged, such as in certain emerging markets, may result in future earnings and cash flow volatility. The gross notional amount of all currency exchange rate derivative instruments outstanding at October 27, 2023 and April 28, 2023 was $21.3 billion and $22.0 billion, respectively. At October 27, 2023, these contracts were in a net unrealized gain position of $662 million. Additional information regarding our currency exchange rate derivative instruments is included in Note 8 to the current period's consolidated financial statements.

A sensitivity analysis of changes in the fair value of all currency exchange rate derivative contracts at October 27, 2023 indicates that, if the U.S. dollar uniformly strengthened/weakened by 10 percent against all currencies, the fair value of these contracts would increase/decrease by approximately $1.6 billion. Any gains and losses on the fair value of derivative contracts would generally be offset by gains and losses on the underlying transactions. These offsetting gains and losses are not reflected in the above analysis.

INTEREST RATE RISK

We are subject to interest rate risk on our short-term investments and our borrowings. We manage interest rate risk in the aggregate, while focusing on our immediate and intermediate liquidity needs. Our debt portfolio at October 27, 2023 was comprised of debt predominantly denominated in U.S. dollars and Euros, of which substantially all is fixed rate debt. We are also exposed to interest rate changes affecting our investments in interest rate sensitive instruments, which include our marketable debt securities.

A sensitivity analysis of the impact on our interest rate-sensitive financial instruments of a hypothetical 50 basis point change in interest rates, as compared to interest rates at October 27, 2023, indicates that the fair value of these instruments would correspondingly change by $57 million.
