Debt Instruments [Abstract]
Credit Facilities	Credit Facilities On March 20, 2012, the Company entered into a credit agreement with certain lenders (the “Prior Lenders”) and Jefferies Finance LLC, as administrative and collateral agent (the “Prior Credit Agreement”). Pursuant to the Prior Credit Agreement, the Prior Lenders provided the Company with senior secured first lien credit facilities in an aggregate principal amount of $350 million (the “Prior Credit Facilities”), consisting of term A loans in an aggregate principal amount of $100 million (the “Term A Loans”) and term B loans in an aggregate principal amount of $250 million (the “Term B Loans”). The initial carrying amounts totaled $99.5 million (net of original issue discount of $0.5 million) for the Term A Loans and $247.5 million (net of original issue discount of $2.5 million) for the Term B Loans. The respective amounts of original issue discount are being amortized using the effective interest method and are included in “Interest expense” in the consolidated statements of income. Debt issuance costs incurred in connection with the Prior Credit Agreement totaled $8.9 million and are being amortized using the effective interest method over the terms of the loans, and are included in “Interest expense” in the unaudited consolidated condensed statements of income. Interest on the Term A Loans and Term B Loans accrued at certain reference rates plus specified applicable margins. The reference rates are equivalent to, at the Company’s option, either: (i) LIBOR for interest periods of 1, 2, 3 or 6 months or, subject to certain conditions, 9 or 12 months (“LIBOR”) or (ii) the highest of (a) the prime rate, (b) the federal funds effective rate plus 1/2% or (c) one-month LIBOR plus 1.00% (“Base Rate”). For the Term B Loans, LIBOR was subject to a floor of 1.00% and Base Rate was subject to a floor of 2.00%. For the Term A Loans, the applicable margin for LIBOR loans ranged from 2.50% to 2.75% and the applicable margin for Base Rate loans ranged from 1.50% to 1.75%, in each case depending upon the total leverage ratio. For the Term B Loans, the applicable margin for LIBOR loans was 3.25% and the applicable margin for Base Rate loans was 2.25%. Interest was payable at least quarterly. As of April 28, 2013, the interest rates payable on the Term A Loans and Term B Loans were 2.95% and 4.25%, respectively. In accordance with the Prior Credit Agreement, and as described in Note 11, in June 2012, the Company entered into an interest rate hedging agreement protecting at least 50% of the variable interest rate exposure on the term loans. Pursuant to the Prior Credit Agreement, under certain circumstances, the Company was obligated to apply 50% of its excess cash flow (as defined in the Prior Credit Agreement) for each fiscal year, as well as net cash proceeds from specified other sources, such as asset sales, debt issuances or insurance proceeds, to prepay the Term A Loans and Term B Loans. Excess cash flow may be primarily summarized as cash provided by operating activities less capital expenditures and loan principal payments. The earliest date that any such payment may be due was 95 days after the last day of the fiscal year ending closest to January 31, 2013. On May 2, 2013, the Company entered into new senior secured first lien credit facilities (the “New Credit Agreement”) in an aggregate principal amount of $400 million to replace its existing $350 million Prior Credit Facilities. As a result, the Company is no longer obligated to make the early excess cash flows payment for the Prior Credit Facilities discussed above. As of April 28, 2013, the current portion of the long-term debt of $13.5 million has been recorded based on payments that will be made for the New Credit Agreement in the next twelve months. In addition, the Company has classified the early prepayment of $26 million for the New Credit Agreement from “Long term debt” to “Current portion - long term debt” in the unaudited consolidated condensed balance sheets as of April 28, 2013. The prepayment of $26 million was made on June 3, 2013. The terms of the New Credit Agreement are discussed in Note 17.

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.
