Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The Company manufactures and distributes kitchen cabinets and vanities for the remodeling and new home construction markets. The Company's products are sold across the United States through a network of independent dealers and distributors and directly to home centers and major builders. The following is a description of the Company’s significant accounting policies: Principles of Consolidation and Basis of Presentation: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. Significant inter-company accounts and transactions have been eliminated in consolidation. Revenue Recognition: The Company recognizes revenue when product is delivered to the customer and title has passed. Revenue is based on invoice price less allowances for sales returns, cash discounts and other deductions. Cost of Sales and Distribution: Cost of sales and distribution includes all costs associated with the manufacture and distribution of the Company’s products including the costs of shipping and handling. Advertising Costs: Advertising costs are expensed as incurred. Advertising expenses for fiscal years 2017, 2016 and 2015 were $41.0 million, $38.1 million and $34.3 million, respectively. Cash and Cash Equivalents: Cash in excess of operating requirements is invested in money market accounts which are carried at cost (which approximates fair value). The Company considers all highly liquid short-term investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents were $50.1 million and $34.0 million at April 30, 2017 and 2016, respectively. Investments in Certificates of Deposit: The Company invests excess cash in certificates of deposit which are carried at cost (which approximates fair value). Certificates of deposit with original maturities greater than three months and remaining maturities less than one year are classified as current assets. Certificates of deposit with remaining maturities greater than one year are classified as long-term assets. Inventories: Inventories are stated at lower of cost or market. Inventory costs are determined by the last-in, first-out (LIFO) method. The LIFO cost reserve is determined in the aggregate for inventory and is applied as a reduction to inventories determined on the first-in, first-out method (FIFO). FIFO inventory cost approximates replacement cost. Property, Plant and Equipment: Property, plant and equipment is stated on the basis of cost less accumulated depreciation. Depreciation is provided by the straight-line method over the estimated useful lives of the related assets, which range from 15 to 30 years for buildings and improvements and 3 to 10 years for machinery and equipment. Assets under capital leases are amortized over the shorter of their estimated useful lives or the term of the related lease. Impairment of Long-Lived Assets: The Company reviews its long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. During fiscal years 2017, 2016 and 2015, the Company concluded no impairment existed, except for impairments related to restructuring activities. Promotional Displays: The Company invests in promotional displays in retail stores to demonstrate product features, product and quality specifications and to serve as a training tool for retail kitchen designers. The Company invests in these long-lived productive assets to provide the aforementioned benefits. The Company's investment in promotional displays is carried at cost less applicable amortization. Amortization is provided by the straight-line method on an individual display basis over periods of 30 to 36 months (the estimated period of benefit). Promotional display amortization expense for fiscal years 2017, 2016 and 2015 was $3.4 million, $3.4 million and $3.6 million, respectively, and is included in selling and marketing expenses. Income Taxes: The Company accounts for deferred income taxes utilizing the asset and liability method, whereby deferred tax assets and liabilities are recognized based on the tax effects of temporary differences between the financial statement amounts and the tax basis of assets and liabilities, using enacted tax rates in effect for the year in which these items are expected to reverse. At each reporting date, the Company evaluates the need for a valuation allowance to adjust deferred tax assets and liabilities to an amount that more likely than not will be realized. Pensions: The Company has two non-contributory defined benefit pension plans covering many of the Company’s employees hired before April 30, 2012. Both defined benefit pension plans were frozen effective April 30, 2012. The Company recognizes the overfunded or underfunded status of its defined benefit pension plans, measured as the difference between the fair value of plan assets and the benefit obligation, in its consolidated balance sheets. The Company also recognizes the actuarial gains and losses and the prior service costs, credits and transition costs as a component of other comprehensive income (loss), net of tax. Stock-Based Compensation: The Company recognizes stock-based compensation expense based on the grant date fair value over the requisite service period. Self Insurance: The Company is self-insured for certain costs related to employee medical coverage, workers’ compensation liability, general liability, auto liability and property insurance. The Company maintains stop-loss coverage with third-party insurers to limit total exposure. The Company establishes a liability at each balance sheet date based on estimates for a variety of factors that influence the Company’s ultimate cost. In the event that actual experience is substantially different from the estimates, the financial results for the period could be adversely affected. The Company believes that the methodologies used to estimate insurance liabilities are an accurate reflection of the liabilities as of the date of the balance sheet. Recent Accounting Pronouncements: In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, “Revenue from Contracts with Customers: Topic 606.” ASU 2014-09 supersedes the revenue recognition requirements in “Accounting Standard Codification 605 - Revenue Recognition” and most industry-specific guidance. The standard requires that entities recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which a company expects to be entitled in exchange for those goods or services. ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date." ASU 2015-14 defers the effective date of ASU 2014-09 by one year to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that period. The Company does not expect the adoption of ASU 2014-09 and ASU 2015-14 to have a material impact on results of operations, cash flows and financial position. The Company is continuing to evaluate the impact of ASU 2014-09 primarily to determine the transition method to utilize at adoption and the additional disclosures required. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)." ASU 2016-02 requires lessees to recognize most leases on-balance sheet, which will increase reported assets and liabilities. Lessor accounting remains substantially similar to current U.S. GAAP. ASU 2016-02 supersedes "Topic 840 - Leases." ASU 2016-02 is effective for public companies for annual and interim periods in fiscal years beginning after December 15, 2018. ASU 2016-02 mandates a modified retrospective transition method for all entities. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements, however, if at adoption the Company has similar obligations for leases as it had at April 30, 2017, the Company believes this guidance will not have a material impact on its results of operations, cash flows and financial position. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Shares-Based Payment Accounting.” ASU 2016-09 is intended to improve the accounting for share-based payment transactions as part of the FASB’s simplification initiative. ASU 2016-09 changes several aspects of the accounting for share-based payment award transactions, including: (1) accounting for income taxes; (2) classification of excess tax benefits on the statement of cash flows; (3) forfeitures; (4) minimum statutory tax withholding requirements; and (5) classification of employee taxes paid on the statement of cash flows when an employer withholds shares for tax-withholding purposes. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those years for public companies. The Company early adopted this standard as of May 1, 2016. As a result, during fiscal 2017, it recognized the excess tax benefit of $1.3 million as income tax benefit on the condensed consolidated statements of income (adopted prospectively). The adoption did not impact the existing classification of the awards. Excess tax benefits from stock based compensation is now classified in net income in the statement of cash flows instead of being separately stated in financing activities for the twelve months ended April 30, 2017 (adopted prospectively). Additionally, the Company reclassified $2.8 million and $1.4 million of employee withholding taxes paid from operating activities into financing activities in the statement of cash flows for the twelve month periods ended April 30, 2016 and 2015, respectively, as required by ASU 2016-09 (adopted retrospectively). Following the adoption of the new standard, the Company elected to continue estimating the number of awards expected to be forfeited and adjust its estimate on an ongoing basis. In April 2015, the FASB issued ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The Company retrospectively adopted this standard on April 30, 2016, which resulted in the reclassification of approximately $0.3 million of debt issuance costs from other assets to long-term debt as of April 30, 2016. Adoption of the new guidance did not impact the Company's shareholder's equity, results of operations or statements of cash flows. In May 2015, the FASB issued ASU No. 2015-07, Disclosures for Investments in Certain Entities that Calculate Net Asset Value per Share (or its Equivalent), which amends the disclosure requirements of Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures, for reporting entities that measure the fair value of an investment using the net asset value per share (or its equivalent) as a practical expedient. The amendments in ASU 2015-07 remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient and also remove the requirements to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. The Company retrospectively adopted this standard on April 30, 2017, which impacted the disclosure of investments, see Note H for additional information. In March 2017, the FASB issued ASU No. 2017-07, "Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost." ASU 2017-07 requires an employer to disaggregate the service cost component from the other components of net benefit (income) cost. The other components of net benefit (income) cost are required to be presented in the income statement separately from the service cost component and outside of operating income. The amendments also allow only the service cost component of net benefit (income) cost to be eligible for capitalization. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017. The amendments in this ASU should be applied (1) retrospectively for the presentation of the service cost component and the other components of net periodic pension (income) cost and net periodic postretirement benefit (income) cost on the income statement, and (2) prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension (income) cost and net periodic postretirement benefit (income) cost in assets. The Company is evaluating the effect this guidance will have on its results of operations, cash flows and financial position. Use of Estimates: The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during each reporting period. Actual results could differ from those estimates. Reclassifications: Certain reclassifications have been made to prior period balances to conform to the current year presentation.
