Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivative Financial Instruments | Derivative Financial Instruments We enter into foreign currency forward contracts to mitigate the impact of foreign currency exchange rate movements on our operating expenses. These contracts are designated as cash flow hedges for hedge accounting treatment. Gains or losses on the contracts are recorded in accumulated other comprehensive income or loss and reclassified to operating expense when the related operating expenses are recognized in earnings or ineffectiveness should occur. The fair value of the contracts was not significant as of January 31, 2021 and January 26, 2020. We enter into foreign currency forward contracts to mitigate the impact of foreign currency movements on monetary assets and liabilities that are denominated in currencies other than U.S. dollar. These forward contracts were not designated for hedge accounting treatment. Therefore, the change in fair value of these contracts is recorded in other income or expense and offsets the change in fair value of the hedged foreign currency denominated monetary assets and liabilities, which is also recorded in other income or expense. The table below presents the notional value of our foreign currency forward contracts outstanding as of January 31, 2021 and January 26, 2020:
| January 31, 2021 |  | January 26, 2020
| (In millions)
Designated as cash flow hedges | $ | 840 |  |  | $ | 428 |
Not designated for hedge accounting | $ | 441 |  |  | $ | 287 |
As of January 31, 2021, all designated foreign currency forward contracts mature within eighteen months. The expected realized gains and losses deferred into accumulated other comprehensive income (loss) related to foreign currency forward contracts within the next twelve months was not significant. During fiscal years 2021 and 2020, the impact of derivative financial instruments designated for hedge accounting treatment on other comprehensive income or loss was not significant and all such instruments were determined to be highly effective. Therefore, there were no gains or losses associated with ineffectiveness.
