Debt Disclosure [Abstract]
DEBT	NOTE H – DEBT Term Loan: On October 20, 2015, the Company entered into a Term Loan Agreement with Bank of America, N.A. (Term Loan Agreement). The Term Loan Agreement provides for a $300 million term loan (Term Loan) with a maturity date of April 20, 2022. From April 1, 2017 through January 1, 2021, the Term Loan Agreement will require quarterly principal amortization payments in an amount equal to 1.25%, and, commencing April 1, 2021 and thereafter, 2.50%, of the stated principal amount of the Term Loan made on the funding date of October 22, 2015. The Company may, at any time on or after October 20, 2016, prepay the outstanding principal amount of the Term Loan in whole or in part without premium or penalty. The Term Loan will bear interest at a rate dependent on the Company’s credit ratings applicable from time to time and, at the Company’s option, will be calculated according to a base rate or a Eurodollar rate, as the case may be, plus an applicable margin. Depending on the Company’s credit ratings, the applicable margin for any portion of the Term Loan accruing interest based on the base rate ranges from 0.125% to 1.000% and the applicable margin for any portion of the Term Loan accruing interest based on the Eurodollar rate ranges from 1.125% to 2.000%. At the Company’s current credit ratings, the applicable margin would be 0.500% for interest at the base rate and 1.500% for interest at the Eurodollar rate. The Term Loan Agreement provides that the Company may use the proceeds of the Term Loan for general corporate purposes of the Company and its subsidiaries, which may include, but is not limited to, share repurchases, acquisitions and the refinancing of existing indebtedness. The Term Loan Agreement also contains covenants and events of default consistent with the Company’s revolving credit facility. 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 nine months ended December 31, 2015. At December 31, 2015 and March 31, 2015, there were no outstanding borrowings under the revolving credit facility.
