Debt Disclosure [Abstract]
DEBT	NOTE H – DEBT Senior Notes: In August 2015, the Company issued $400 million of 3.600% Senior Notes due August 2020 (3.600% Notes) for proceeds of approximately $400 million, reflecting a discount of less than $1 million. The 3.600% Notes are senior unsecured obligations that rank equally in right of payment with all of the Company’s existing and future unsecured and unsubordinated obligations and are redeemable by the Company at any time, subject to a “make-whole” premium of 30 basis points. Interest on the 3.600% Notes is payable semiannually in February and August, beginning February 2016. In the event of a change of control, each note holder will have the right to require the Company to repurchase all or any part of the holder’s 3.600% Notes in cash at a price equal to 101% of the principal amount of such 3.600% Notes plus accrued and unpaid interest, if any, to the date of repurchase. This is subject to the right of holders of record on the relevant interest payment date to receive interest due. The 3.600% Notes contain customary covenants and events of default. The maturity of the 3.600% Notes may be accelerated by holders upon certain events of default, including failure to make payments when due and failure to comply with covenants. The Company capitalized transaction costs of approximately $3 million associated with the 3.600% Notes and will amortize these costs to “Interest expense, net” in the Company's Condensed Consolidated Statements of Operations. Revolving Credit Facility: In April 2015, the Company amended its revolving credit facility to extend the termination date from June 2018 to June 2019. The maximum committed amount available under the revolving credit facility is $1 billion. The facility also provides the Company with an option to increase the available credit by an amount up to $500 million. This option is subject to certain conditions and the agreement of the facility lenders. The Company capitalized transaction costs of less than $1 million associated with the April 2015 amendment of the revolving credit facility. These fees are being amortized to “Interest expense, net” in the Company’s Condensed Consolidated Statements of Operations. In July 2015 and in connection with the acquisition of Rally, the Company borrowed $400 million under its revolving credit facility. The interest rate applicable to the Company at the time of borrowing under the revolving credit facility was approximately 1.19%. In August 2015, the Company repaid the $400 million borrowing under its revolving credit facility with proceeds received from the Company’s issuance of the 3.600% Notes described above. Interest expense in connection with the borrowing under the revolving credit facility was less than $1 million for the three and six months ended September 30, 2015. At September 30, 2015 and March 31, 2015, there were no outstanding borrowings under the revolving credit facility.
