Debt Disclosure [Abstract]
Long-Term Debt	NOTE 3 – Long-Term Debt Credit Facility On December 14, 2010, the Company entered into an Amended and Restated Credit Facility Agreement (Credit Facility), with Bank of America, N.A. The Credit Facility was an unsecured credit agreement providing for (i) a $100.0 million revolving credit facility, including a $100.0 million alternative currency borrowing sublimit and a $50.0 million letter of credit sublimit and (ii) a term loan facility of $400.0 million. On September, 29, 2011, the Company amended the Credit Facility increasing the amount of the term loan facility from $400.0 million to $500.0 million. Credit Agreement On December 3, 2014, the Company entered into a Credit Agreement with Wells Fargo Bank, National Association, as administrative agent, and Bank of America, N.A., as syndication agent, which superseded the Credit Facility. The Credit Agreement provides for (a) a secured revolving loan facility in an aggregate principal amount of up to $300.0 million, none of which was drawn at closing, or at October 31, 2015 (Revolving Loan Facility), and (b) a secured term loan facility in an aggregate principal amount of $300.0 million (Term Loan), which was fully drawn at closing. Proceeds from the Credit Agreement were used to repay all outstanding amounts under the Credit Facility totaling $275.0 million at December 3, 2014. The remaining proceeds are being used for general corporate purposes. The Revolving Loan Facility and the Term Loan facility mature on December 3, 2019. The Term Loan, which as of October 31, 2015, had $225.0 million outstanding, amortizes $18.8 million each quarter beginning December 31, 2014 through December 31, 2015, then amortizes $7.5 million each quarter, with all outstanding borrowings due on December 3, 2019. All amounts borrowed under the Term Loan may be prepaid without premium or penalty. The Revolving Loan Facility and Term Loan under the Credit Agreement bear interest, at the election of the Company, at either (a) the Base Rate, which is defined as a fluctuating rate per annum equal to the greatest of (i) the Prime Rate in effect on such day; (ii) the Federal Funds Rate in effect on such date plus 0.50%; or (iii) an adjusted LIBOR rate determined on the basis of a one-month interest period plus 1.0%, in each case plus an applicable margin ranging from 0.25% to 1.0% based on the Company’s consolidated total net leverage ratio during the preceding fiscal quarter; or (b) an adjusted LIBOR rate plus an applicable margin ranging from 1.25% to 2.0% depending on the Company’s consolidated total net leverage ratio during the preceding fiscal quarter. Interest is due and payable quarterly, in arrears, for loans bearing interest at the Base Rate, and at the end of an interest period (or at each three month interval in the case of loans with interest periods greater than three months) in the case of loans bearing interest at the adjusted LIBOR rate. The interest rate as of October 31, 2015 on the Company’s variable interest rate debt was the one month LIBOR rate of 0.19% plus an applicable margin of 1.25%. The carrying amount of the Credit Agreement is comprised of borrowings under which interest accrues under a fluctuating interest rate structure. Accordingly, the carrying value approximates fair value at October 31, 2015, and was classified within Level II of the fair value hierarchy. Amounts borrowed under the Revolving Loan Facility may be repaid and reborrowed until the maturity date of December 3, 2019. The Company is obligated to pay a commitment fee on the unused portion of the Revolving Loan Facility. The commitment fee rate ranges from 0.20% to 0.35%, depending on the Company’s consolidated total net leverage ratio during the preceding fiscal quarter, on the average daily unused portion of the revolving credit commitment under the Credit Agreement. The Company had no outstanding borrowings under the Revolving Loan Facility as of October 31, 2015. The Company’s obligations under the Credit Agreement are guaranteed by certain of the Company’s domestic subsidiaries meeting materiality thresholds set forth in the Credit Agreement. Such obligations, including the guaranties, are secured by substantially all of the assets of the Company and the assets of the subsidiary guarantors pursuant to a Security Agreement, dated December 3, 2014, among the Company, the subsidiary guarantors from time to time party thereto, and Wells Fargo Bank, National Association, as collateral agent. The Credit Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries’ ability to, among other things, incur indebtedness, grant liens, merge or consolidate, dispose of assets, make investments, make acquisitions, enter into transactions with affiliates, pay dividends, or make distributions on and repurchase stock, in each case subject to certain exceptions. The Company is also required to maintain compliance, measured at the end of each fiscal quarter, with a consolidated total net leverage ratio and a consolidated interest coverage ratio. The Company was in compliance with all covenants related to the Credit Agreement as of October 31, 2015. Note Purchase Agreement On December 3, 2014, the Company entered into a Note Purchase Agreement and sold to certain purchasers (collectively, the Purchasers) $400.0 million in aggregate principal amount of senior secured notes (Senior Notes) consisting of (i) $100.0 million aggregate principal amount of 4.07% Senior Notes, Series A, due December 3, 2024; (ii) $100.0 million aggregate principal amount of 4.19% Senior Notes, Series B, due December 3, 2026; (iii) $100.0 million aggregate principal amount of 4.25% Senior Notes, Series C, due December 3, 2027; and (iv) $100.0 million aggregate principal amount of 4.35% Senior Notes, Series D, due December 3, 2029. Interest is due and payable quarterly, in arrears, on each of the Senior Notes. Proceeds from the Note Purchase Agreement are being used for general corporate purposes. The Company may prepay the Senior Notes, in whole or in part, at any time, subject to certain conditions, including minimum amounts and payment of a make-whole amount equal to the discounted value of the remaining scheduled interest payments under the Senior Notes. The Company’s obligations under the Note Purchase Agreement are guaranteed by certain of the Company’s domestic subsidiaries meeting materiality thresholds set forth in the Note Purchase Agreement. Such obligations, including the guaranties, are secured by substantially all of the assets of the Company and the subsidiary guarantors. The obligations of the Company and its subsidiary guarantors under the Note Purchase Agreement will be treated on a pari passu basis with the obligations of those entities under the Credit Agreement as well as any additional debt the Company may obtain. The Note Purchase Agreement contains customary affirmative and negative covenants, including covenants that limit or restrict the Company and its subsidiaries’ ability to, among other things, incur indebtedness, grant liens, merge or consolidate, dispose of assets, make investments, make acquisitions, enter into transactions with affiliates, pay dividends, or make distributions and repurchase stock, in each case subject to certain exceptions. The Company is also required to maintain compliance, measured at the end of each fiscal quarter, with a consolidated total net leverage ratio and a consolidated interest coverage ratio. The Company was in compliance with all covenants related to the Note Purchase Agreement as of October 31, 2015. Related to the execution of the Credit Agreement and the Note Purchase Agreement, the Company incurred $2.1 million in costs, of which $1.0 million was capitalized as debt issuance fees and $1.1 million was recorded as a reduction of the long-term debt proceeds as a debt discount. Both the debt issuance fees and debt discount are amortized to interest expense over the term of the respective debt instruments.
