Debt Disclosure [Abstract]
Loans Payable and Long-Term Debt	Loans Payable and Long-Term Debt On December 29, 2017, the Company entered into a credit agreement (as subsequently amended, the "Credit Agreement") with a syndicate of lenders and Wells Fargo Bank, National Association, as administrative agent, providing for a $100 million, 5-year revolving loan facility with a $25 million sub-facility for the issuance of letters of credit (the “Revolving Facility”), a $250 million, 5-year initial term loan facility (the "Initial Term Loan") and a $250 million delayed draw term loan facility (the "Delayed Draw Term Loan" and, together with the Revolving Facility and the Initial Term Loan, the "Credit Facilities"). The Company borrowed the entire $250 million available under each of the Initial Term Loan and the Delayed Draw Term Loan on December 29, 2017 and February 12, 2018, respectively, in connection with its acquisition of RSI Home Products, Inc. (“RSI”) and subsequent refinancing of RSI’s debt. The Company is required to make specified quarterly installments on both the Initial Term Loan and the Delayed Draw Loan. As of October 31, 2019, $134 million was outstanding on each of the Initial Term Loan and the Delayed Draw Loan for a total of $268 million. As of April 30, 2019, $170 million was outstanding on each of the Initial Term Loan and the Delayed Draw Loan for a total of $340 million. The outstanding balance approximates fair value as the Initial Term Loan and Delayed Draw Term Loan have a floating interest rate. There were no amounts outstanding on the Revolving Facility as of October 31, 2019 or April 30, 2019. The Credit Facilities mature on December 29, 2022. Amounts outstanding under the Credit Facilities bear interest based on a fluctuating rate measured by reference to either, at the Company’s option, a base rate plus an applicable margin or LIBOR plus an applicable margin, with the applicable margin being determined by reference to the Company’s then-current “Total Funded Debt to EBITDA Ratio.” The Company also incurs a quarterly commitment fee on the average daily unused portion of the Revolving Facility during the applicable quarter at a rate per annum also determined by reference to the Company’s then-current “Total Funded Debt to EBITDA Ratio.” In addition, a letter of credit fee will accrue on the face amount of any outstanding letters of credit at a per annum rate equal to the applicable margin on LIBOR loans, payable quarterly in arrears. As of October 31, 2019, the applicable margin with respect to base rate loans and LIBOR loans was 0.50% and 1.50%, respectively, and the commitment fee was 0.18%. The Credit Agreement includes certain financial covenants, including a maximum “Total Funded Debt to EBITDA Ratio” as of the last day of any fiscal quarter ending through January 31, 2020 of no more than 3.50 to 1.00 and thereafter, of no more than 3.25 to 1.00 (with an increase to 3.75 to 1.00 for a certain period upon the consummation of a “Qualified Acquisition”). The Company is also required to maintain a “Fixed Charge Coverage Ratio” of no less than 1.25 to 1.00. The Credit Agreement includes certain additional covenants, including negative covenants that restrict the ability of the Company and certain of its subsidiaries to incur additional indebtedness, create additional liens on its assets, dispose of its assets or engage in a merger or another similar transaction or engage in transactions with affiliates, subject, in each case, to the various exceptions and conditions described in the Credit Agreement. The negative covenants also restrict the Company’s ability to make certain investments and to make certain restricted payments, including the payment of dividends and repurchase of common stock, in certain limited circumstances. The Company is, however, permitted to make unlimited investments so long as the “Total Funded Debt to EBITDA Ratio” is less than or equal to 3.00 to 1.00 after giving effect to any such investment and no default or event of default has occurred and is continuing or would result from any such investment. The Company is also permitted to make (i) unlimited restricted payments so long as the “Total Funded Debt to EBITDA Ratio” would be less than or equal to 2.75 to 1.00 after giving effect to any such payment and no default or event of default has occurred and is continuing or would result from any such payment and (ii) up to an aggregate of $50 million in restricted payments not otherwise permitted under the Credit Agreement so long as no default or event of default has occurred and is continuing or would result from any such payment. As of October 31, 2019, the Company was in compliance with the covenants included in the Credit Agreement. The Company’s obligations under the Credit Agreement are guaranteed by the Company’s subsidiaries and the obligations of the Company and its subsidiaries are secured by a pledge of substantially all of their respective personal property. On February 12, 2018, the Company issued $350 million in aggregate principal amount of 4.875% Senior Notes due 2026 (the “Senior Notes”). The Senior Notes mature on March 15, 2026 and interest on the Senior Notes is payable semi-annually in arrears on March 15 and September 15 of each year. The Senior Notes are fully and unconditionally guaranteed by each of the Company’s current and future wholly-owned domestic subsidiaries that guarantee the Company’s obligations under the Credit Agreement. The indenture governing the Senior Notes restricts the ability of the Company and the Company’s “restricted subsidiaries” to, as applicable, (i) incur additional indebtedness or issue certain preferred shares, (ii) create liens, (iii) pay dividends, redeem or repurchase stock or make other distributions or restricted payments, (iv) make certain investments, (v) create restrictions on the ability of the “restricted subsidiaries” to pay dividends to the Company or make other intercompany transfers, (vi) transfer or sell assets, (vii) merge or consolidate with a third party and (viii) enter into certain transactions with affiliates of the Company, subject, in each case, to certain qualifications and exceptions as described in the indenture. As of October 31, 2019, the Company and its restricted subsidiaries were in compliance with all covenants under the indenture governing the Senior Notes. At October 31, 2019, the book value of the Senior Notes was $350 million and the fair value was $357 million, based on Level 1 inputs.
