Accounting Policies [Abstract]
Derivatives, Policy	Hedge Accounting and Hedging Programs We recognize derivative instruments and hedging activities as either assets or liabilities in our condensed consolidated balance sheets and measure them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting. We evaluate hedge effectiveness at the inception of the hedge prospectively as well as retrospectively, and record any ineffective portion of the hedging instruments in interest and other income (expense), net on our condensed consolidated statements of income. The net gain (loss) recognized in interest and other income (expense), net for cash flow hedges due to hedge ineffectiveness was insignificant for all fiscal years presented. The time value of purchased contracts is recorded in interest and other income (expense), net in our condensed consolidated statements of income. The bank counterparties to these contracts expose us to credit-related losses in the event of their nonperformance which are largely mitigated with collateral security agreements that provide for collateral to be received or posted when the net fair value of certain financial instruments fluctuates from contractually established thresholds. In addition, we enter into master netting arrangements which have the ability to further limit credit-related losses with the same counterparty by permitting net settlement of transactions. Balance Sheet Hedging—Hedges of Foreign Currency Assets and Liabilities We also hedge our net recognized foreign currency denominated assets and liabilities with foreign exchange forward contracts to reduce the risk that the value of these assets and liabilities will be adversely affected by changes in exchange rates. These contracts hedge assets and liabilities that are denominated in foreign currencies and are carried at fair value with changes in the fair value recorded to interest and other income (expense), net in our condensed consolidated statements of income. These contracts do not subject us to material balance sheet risk due to exchange rate movements because gains and losses on these derivatives are intended to offset gains and losses on the assets and liabilities being hedged. Cash Flow Hedging—Hedges of Forecasted Foreign Currency Revenue and Interest Rate Risk In countries outside the United States, we transact business in U.S. Dollars and in various other currencies. We may use foreign exchange option contracts or forward contracts to hedge certain cash flow exposures resulting from changes in these foreign currency exchange rates. These foreign exchange contracts, carried at fair value, have maturities of up to twelve months. We enter into these foreign exchange contracts to hedge a portion of our forecasted foreign currency denominated revenue in the normal course of business and accordingly, they are not speculative in nature. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge, and the hedges must be highly effective in offsetting changes to future cash flows on hedged transactions. We record changes in the intrinsic value of these cash flow hedges in accumulated other comprehensive income (loss) in our condensed consolidated balance sheets, until the forecasted transaction occurs. When the forecasted transaction occurs, we reclassify the related gain or loss on the cash flow hedge to revenue. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, we reclassify the gain or loss on the related cash flow hedge from accumulated other comprehensive income (loss) to interest and other income (expense), net in our condensed consolidated statements of income at that time. If we do not elect hedge accounting, or the contract does not qualify for hedge accounting treatment, the changes in fair value from period to period are recorded in interest and other income (expense), net in our condensed consolidated statements of income. Fair Value Hedging - Hedges of Interest Rate Risk In fiscal 2014, we entered into interest rate swaps designated as fair value hedges related to our $900 million of 4.75% fixed interest rate senior notes due February 1, 2020. In effect, the interest rate swaps convert the fixed interest rate on these senior notes to a floating interest rate based on LIBOR. Under the terms of the swaps, we will pay monthly interest at the one-month LIBOR interest rate plus a fixed number of basis points on the $900 million notional amount through February 1, 2020. In exchange, we will receive 4.75% fixed rate interest from the swap counterparties. See Note 13 for further details regarding our debt. The interest rate swaps are accounted for as fair value hedges and substantially offset the changes in fair value of the hedged portion of the underlying debt that are attributable to the changes in market risk. Therefore, the gains and losses related to changes in the fair value of the interest rate swaps are included in interest and other income (expense), net in our condensed consolidated statements of income. The fair value of the interest rate swaps is reflected in other liabilities or other assets in our condensed consolidated balance sheets.

Hedge Accounting and Hedging Programs

We recognize derivative instruments and hedging activities as either assets or liabilities in our condensed consolidated balance sheets and measure them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting.

We evaluate hedge effectiveness at the inception of the hedge prospectively as well as retrospectively, and record any ineffective portion of the hedging instruments in interest and other income (expense), net on our condensed consolidated statements of income. The net gain (loss) recognized in interest and other income (expense), net for cash flow hedges due to hedge ineffectiveness was insignificant for all fiscal years presented. The time value of purchased contracts is recorded in interest and other income (expense), net in our condensed consolidated statements of income.

Balance Sheet Hedging—Hedges of Foreign Currency Assets and Liabilities

We also hedge our net recognized foreign currency denominated assets and liabilities with foreign exchange forward contracts to reduce the risk that the value of these assets and liabilities will be adversely affected by changes in exchange rates. These contracts hedge assets and liabilities that are denominated in foreign currencies and are carried at fair value with changes in the fair value recorded to interest and other income (expense), net in our condensed consolidated statements of income. These contracts do not subject us to material balance sheet risk due to exchange rate movements because gains and losses on these derivatives are intended to offset gains and losses on the assets and liabilities being hedged.

In countries outside the United States, we transact business in U.S. Dollars and in various other currencies. We may use foreign exchange option contracts or forward contracts to hedge certain cash flow exposures resulting from changes in these foreign currency exchange rates. These foreign exchange contracts, carried at fair value, have maturities of up to twelve months.

In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, we reclassify the gain or loss on the related cash flow hedge from accumulated other comprehensive income (loss) to interest and other income (expense), net in our condensed consolidated statements of income at that time.

Fair Value Hedging - Hedges of Interest Rate Risk

In fiscal 2014, we entered into interest rate swaps designated as fair value hedges related to our $900 million of 4.75% fixed interest rate senior notes due February 1, 2020. In effect, the interest rate swaps convert the fixed interest rate on these senior notes to a floating interest rate based on LIBOR. Under the terms of the swaps, we will pay monthly interest at the one-month LIBOR interest rate plus a fixed number of basis points on the $900 million notional amount through February 1, 2020. In exchange, we will receive 4.75% fixed rate interest from the swap counterparties. See Note 13 for further details regarding our debt.

The interest rate swaps are accounted for as fair value hedges and substantially offset the changes in fair value of the hedged portion of the underlying debt that are attributable to the changes in market risk. Therefore, the gains and losses related to changes in the fair value of the interest rate swaps are included in interest and other income (expense), net in our condensed consolidated statements of income. The fair value of the interest rate swaps is reflected in other liabilities or other assets in our condensed consolidated balance sheets.
