Long-Term Debt	NOTE 3 – Long-Term Debt On December 14, 2010, the Company entered into an Amended and Restated Credit Facility Agreement (Credit Facility), which supersedes the Company’s previously disclosed credit agreement with Bank of America, N.A. (Bank of America). The Credit Facility is 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 (Revolving Credit) and (ii) a term loan facility of $400.0 million (Term Loan). On January 14, 2011, the full $400.0 million provided under the Term Loan was borrowed. On September, 29, 2011, the Company amended the credit agreement increasing the amount of the Term Loan facility from $400.0 million to $500.0 million. On March 1, 2013, the Company amended the credit agreement to increase the net leverage ratio at which restrictive spending covenants are introduced from 1:1 to 1.5:1. The Term Loan, which at April 30, 2013 had $387.5 million outstanding, amortizes $18.8 million each quarter beginning December 31, 2011, with all outstanding borrowings due on December 14, 2015. All amounts borrowed under the Term Loan may be prepaid without premium or penalty. Amounts borrowed under the Credit Facility bear interest, subject to certain restrictions, at a fluctuating rate based on (i) the Eurocurrency Rate; (ii) the Federal Funds Rate; or (iii) the Prime Rate as described in the Credit Facility. The Company has entered into two interest rate swaps (see Note 4. Derivatives and Hedging) to exchange its variable interest rate payments commitment for fixed interest rate payments on the Term Loan balance, which at April 30, 2013, totaled $387.5 million. A default interest rate applies on all obligations during an event of default under the credit facility, at a rate per annum equal to 2.0% above the otherwise applicable interest rate. The Company’s interest rate at April 30, 2013 is the 0.20% Eurocurrency Rate plus the 1.75% Applicable Rate. The Applicable Rate can fluctuate between 1.5% and 2.0% depending on the Company’s consolidated net leverage ratio (as defined in the Credit Facility). The Credit Facility is guaranteed by the Company’s material domestic subsidiaries. The carrying amount of the Credit Facility is comprised of borrowing under which interest accrues under a fluctuating interest rate structure. Accordingly, the carrying value approximates fair value at April 30, 2013 and is classified within Level II of the fair value hierarchy. Amounts borrowed under the Revolving Credit may be repaid and reborrowed until the maturity date, which is December 14, 2015. The Credit Facility requires the Company to pay a commitment fee on the unused portion of the Revolving Credit. The commitment fee ranges from 0.075% to 0.125% per annum depending on the Company's leverage ratio. The Company had no outstanding borrowings under the Revolving Credit at the end of the period. The Credit Facility contains customary representations and warranties and may place certain business operating restrictions on the Company relating to, among other things, indebtedness, liens and other encumbrances, investments, mergers and acquisitions, asset sales, dividends and distributions and redemptions of capital stock. In addition, the Credit Facility provides for the following financial covenants: (i) earnings before income tax, depreciation and amortization (EBITDA); (ii) leverage ratio; (iii) interest coverage ratio; and (iv) limitations on capital expenditures. The Credit Facility contains events of default that include, among others, non-payment of principal, interest or fees, violation of covenants, inaccuracy of representations and warranties, cross-defaults to certain other indebtedness, bankruptcy and insolvency defaults, material judgments, invalidity of the loan documents and events constituting a change of control. The Company is in compliance with all covenants as of April 30, 2013.
