Foreign Currency Derivative Instruments [Abstract]
Foreign Currency Derivative Instruments	Note 7-Foreign Currency Derivative Instruments As a large global organization, the Company faces exposure to adverse movements in foreign currency exchange rates. During the ordinary course of business, the Company enters into certain contracts denominated in foreign currency. Potential foreign currency exposures arising from these contracts are analyzed during the contract bidding process. The Company generally manages these transactions by incurring costs to service contracts in the same currency in which revenue is received. Short-term contract financing requirements are met by borrowing in the same currency. By generally matching revenues, costs and borrowings to the same currency, the Company has been able to substantially mitigate foreign currency risk to earnings. However, as business practices evolve, the Company is increasing its use of offshore support and is therefore becoming more exposed to currency fluctuations. The Company established policies and procedures to manage the exposure to fluctuations in foreign currency by using short-term foreign currency forwards and option contracts to manage risk of certain foreign currency assets and liabilities, including intercompany loans, and certain revenue streams denominated in non-functional currencies. For accounting purposes, these foreign currency contracts are not designated as hedges, as defined under ASC 815, “Derivatives and Hedging” and all changes in fair value are reported as part of other (income) expense, but the Company uses these instruments as economic hedges and not for speculative or trading purposes. The notional amount of the foreign currency forward contracts outstanding as of December 30, 2011, and April 1, 2011, was $1,590 million and $787 million, respectively. The notional amount of option contracts outstanding as of December 30, 2011, and April 1, 2011, was $957 million and $676 million, respectively. The estimated fair values of the foreign currency derivative assets and liabilities were $12 million and $25 million, respectively, as of December 30, 2011. The estimated fair values of the foreign currency derivative assets and liabilities were $9 million and $4 million, respectively, as of April 1, 2011 (see Note 6). As a result of the use of derivative instruments, the Company is subject to counterparty credit risks. To mitigate this risk, the Company enters into forward and option contracts with several financial institutions and regularly reviews its credit exposure and the creditworthiness of the counterparties. As of December 30, 2011, there were four counterparties with concentration of credit risk and the maximum amount of loss, based on gross fair value of the foreign currency derivative instruments, that the Company would incur is $11 million.

Note 7-Foreign Currency Derivative Instruments

As a large global organization, the Company faces exposure to adverse movements in foreign currency exchange rates. During the ordinary course of business, the Company enters into certain contracts denominated in foreign currency. Potential foreign currency exposures arising from these contracts are analyzed during the contract bidding process. The Company generally manages these transactions by incurring costs to service contracts in the same currency in which revenue is received. Short-term contract financing requirements are met by borrowing in the same currency. By generally matching revenues, costs and borrowings to the same currency, the Company has been able to substantially mitigate foreign currency risk to earnings. However, as business practices evolve, the Company is increasing its use of offshore support and is therefore becoming more exposed to currency fluctuations.

The Company established policies and procedures to manage the exposure to fluctuations in foreign currency by using short-term foreign currency forwards and option contracts to manage risk of certain foreign currency assets and liabilities, including intercompany loans, and certain revenue streams denominated in non-functional currencies. For accounting purposes, these foreign currency contracts are not designated as hedges, as defined under ASC 815, “Derivatives and Hedging” and all changes in fair value are reported as part of other (income) expense, but the Company uses these instruments as economic hedges and not for speculative or trading purposes.

The notional amount of the foreign currency forward contracts outstanding as of December 30, 2011, and April 1, 2011, was $1,590 million and $787 million, respectively. The notional amount of option contracts outstanding as of December 30, 2011, and April 1, 2011, was $957 million and $676 million, respectively.

The estimated fair values of the foreign currency derivative assets and liabilities were $12 million and $25 million, respectively, as of December 30, 2011. The estimated fair values of the foreign currency derivative assets and liabilities were $9 million and $4 million, respectively, as of April 1, 2011 (see Note 6).

As a result of the use of derivative instruments, the Company is subject to counterparty credit risks. To mitigate this risk, the Company enters into forward and option contracts with several financial institutions and regularly reviews its credit exposure and the creditworthiness of the counterparties. As of December 30, 2011, there were four counterparties with concentration of credit risk and the maximum amount of loss, based on gross fair value of the foreign currency derivative instruments, that the Company would incur is $11 million.
