Credit And Term Loan Facilities [Abstract]
Credit And Term Loan Facilities	Note 8. Credit and Term Loan Facilities On February 17, 2012, the Company entered into an amended and restated credit agreement with several lenders (the "Credit Agreement") providing for (i) a $350.0 million senior unsecured revolving credit facility (the "Revolver") and (ii) a $150.0 million senior unsecured term loan facility (the "Term Loan"). The Credit Agreement amended and restated the Company's previous credit agreement dated October 14, 2011 in order to add a new term loan facility primarily to finance a portion of the purchase price for the acquisition of Magma on February 22, 2012. The Credit Agreement terminates on October 14, 2016. Subject to obtaining additional commitments from lenders, the principal amount of the loans provided under the Credit Agreement may be increased by the Company by up to an additional $150.0 million. The Credit Agreement contains financial covenants requiring the Company to operate within a maximum leverage ratio and maintain specified levels of cash, as well as other non-financial covenants. Borrowings bear interest at a floating rate based on a margin over the Company's choice of market observable base rates as defined in the Credit Agreement. At April 30, 2012, borrowings under the Revolver bore interest at LIBOR + 0.975% and borrowings under the Term Loan bore interest at LIBOR + 1.125%. In addition, commitment fees are payable on the Revolver at rates between 0.150% and 0.300% per year based on the Company's leverage ratio on the daily amount of the revolving commitment. As of April 30, 2012, the Company had outstanding balances of $100.0 million under the Revolver and $150.0 million under the Term Loan, respectively, and is in compliance with all covenants. The Company had no outstanding debt balances as of October 31, 2011. Principal payments on a portion of the Term Loan are due in equal quarterly installments of $7.5 million beginning in the third quarter of our fiscal 2012, with the remainder due in October 2016. The Company can elect to make prepayments on the Term Loan, in whole or in part, without premium or penalty. During the three months ended April 30 2012, the Company made no principal repayments under the Credit Agreement. All borrowings under the Revolver are considered short term and $120.0 million of the borrowings under the Term Loan are classified as long term. The Company expects its borrowings under the Revolver will fluctuate from quarter to quarter. These borrowings under the Credit Agreement have a variable interest rate structure and are classified within Level 2 of the fair value hierarchy. The carrying amount of the short-term and long-term debt approximates the estimated fair value.

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.
