Summary Of Significant Accounting Policies	'
	Note A -- 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 2014, 2013 and 2012 were $30.4 million, $36.5 million and $37.4 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 $38.9 million at both April 30, 2014 and 2013.
	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 2014, 2013 and 2012, 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 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 2014, 2013 and 2012 was $3.7 million, $4.0 million and $5.6 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.
	Recent Accounting Pronouncements:  In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-02, “Comprehensive Income (Topic 220): Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component.  In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period.  The ASU does not change the current requirements for reporting net income or other comprehensive income in financial statements.  The Company adopted this guidance effective May 1, 2013 with no significant impact on the Company’s results of operations or 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, including between components of property, plant and equipment.

	Total long-term debt													$	20,453
	The Company’s primary loan agreement is a $35 million secured revolving credit facility which expires on December 31, 2015 with Wells Fargo Bank, N.A. (Wells Fargo).  At April 30, 2014 and 2013, $10 million of loans were outstanding under this facility, and the Company had additional borrowing base availability of $25.0 million.  The Company incurs a fee for amounts not used under the revolving credit facility.  Fees paid by the Company related to non-usage of its current and former credit facilities have been included in interest expense and were $62,730, $61,000 and $54,158 for fiscal years 2014, 2013 and 2012, respectively.
	The Company’s outstanding indebtedness and other obligations to Wells Fargo are secured by substantially all of the Company’s assets.  The Company can borrow under the revolving credit facility up to the lesser of $35 million or the maximum borrowing base (which equals 75% of eligible accounts receivable, 50% of eligible pre bill reserves and up to $20 million for equipment value, each as defined in the agreement) less any outstanding loan balance.  Any outstanding loan balance bears interest at the London Interbank Offered Rate (LIBOR) (0.25% at April 30, 2014) plus 2.37%. Under the terms of the revolving credit facility, the Company must: (1) maintain at the end of each fiscal quarter a ratio of total liabilities to tangible net worth of not greater than 1.4 to 1.0; (2) maintain at the end of each fiscal quarter a ratio of cash flow to fixed charges of not less than 1.25 to 1.0 measured on a rolling four-quarter basis; and (3) comply with other customary affirmative and negative covenants.
	The Company was in compliance with all covenants specified in the amended revolving credit facility as of April 30, 2014,  including as follows: (1) the Company’s ratio of total liabilities to tangible net worth at April 30, 2014 was 0.73 to 1.0; and (2) cash flow to fixed charges for its most recent four quarters was 3.43 to 1.0.
	The revolving credit facility does not limit the Company’s ability to pay dividends or repurchase its common stock as long as the Company is in compliance with these covenants.
	In 2009, the Company entered into a loan agreement with the Board of County Commissioners of Garrett County as part of the Company’s capital investment in land located in Garrett County, Maryland.  This loan agreement is secured by a Deed of Trust on the property and bears interest at a fixed rate of 3%.  The agreement defers principal and interest during the term of the obligation and forgives any outstanding balance at December 31, 2019, if the Company complies with certain employment levels.  The outstanding balance as of April 30, 2014 and 2013 was $1,290,000.
	In 2005, the Company entered into two separate loan agreements with the Maryland Economic Development Corporation and the County Commissioners of Allegany County as part of the Company’s capital investment and operations at the Allegany County, Maryland site.  These loan agreements were amended in 2013 and 2008.  The aggregate balance of these loan agreements was $2,190,000 as of April 30, 2014 and 2013.  The loan agreements expire at December 31, 2018 and bear interest at a fixed rate of 3% per annum.  These loan agreements are secured by mortgages on the manufacturing facility constructed in Allegany County, Maryland.  These loan agreements defer principal and interest during the term of the obligation and forgive any outstanding balance at December 31, 2018, if the Company complies with certain employment levels at the facility.
	In 2002, the Company entered into a loan agreement with the Perry, Harlan, Leslie, Breathitt Regional Industrial Authority (a.k.a. Coalfields Regional Industrial Authority, Inc.) as part of the Company’s capital investment and operations at the Hazard, Kentucky site. This debt facility was a $6 million term loan, which was scheduled to expire November 13, 2017,  and bore interest at a fixed rate of 2% per annum. It was secured by a mortgage on the manufacturing facility constructed in Hazard, Kentucky. The loan required annual debt service payments consisting of principal and interest with a fixed balloon payment of $1.6 million at loan expiration.

StockBased_Compensation

Stock-Based Compensation	12 Months Ended
	Apr. 30, 2014
Stock-Based Compensation [Abstract]	'
Stock-Based Compensation	'
	Note G – Stock-Based Compensation
	The Company has two types of stock-based compensation awards in effect for its employees and directors. The Company has issued stock options since 1986 and restricted stock units (RSUs) since fiscal 2010. Total compensation expense related to stock-based awards for the fiscal years ended April 30, 2014, 2013 and 2012 was $3.3 million, $3.5 million and $3.4 million, respectively.  The Company recognizes stock-based compensation costs net of an estimated forfeiture rate for those shares expected to vest on a straight-line basis over the requisite service period of the award. The Company estimates the forfeiture rates based upon its historical experience.
	Stock Incentive Plans
	At April 30, 2014, the Company had stock option and RSU awards outstanding under four different plans: (1) 1999 stock option plan for employees; (2) second amended and restated 2004 stock incentive plan for employees; (3) 2006 non-employee directors equity ownership plan; and (4) 2011 non-employee directors equity ownership plan.  As of April 30, 2014, there were 1,075,350 shares of common stock available for future stock-based compensation awards under the Company’s stock incentive plans.
	Methodology Assumptions
	For purposes of valuing stock option grants, the Company has identified one employee group and one non-employee director group, based upon observed option exercise patterns. The Company uses the Black-Scholes option-pricing model to value the Company’s stock options for each of the groups. Using this option-pricing model, the fair value of each stock option award is estimated on the date of grant. The fair value of the Company’s stock option awards is expensed on a straight-line basis over the vesting period of the stock options. The expected volatility assumption is based on the historical volatility of the Company’s stock over a term equal to the expected term of the option granted. The expected term of stock option awards granted is derived from the Company’s historical exercise experience and represents the period of time that stock option awards granted are expected to be outstanding for each of the identified groups. The expected term assumption incorporates the contractual term of an option grant, which is generally ten years for employees and from four to ten years for non-employee directors, as well as the vesting period of an award, which is typically three years. The risk-free interest rate is based on the implied yield on a U.S. Treasury constant maturity with a remaining term equal to the expected term of the option granted.
	For purposes of determining the fair value of RSUs, the Company uses the closing stock price of its common stock as reported on the NASDAQ Global Select Market on the date of grant, reduced by the discounted value of future expected dividend payments during the vesting period, since the recipients are not entitled to dividends during the vesting period. The fair value of the Company’s RSU awards is expensed on a straight-line basis over the vesting period of the RSUs to the extent the Company believes it is probable the related performance criteria, if any, will be met.  The risk-free interest rate is based on the implied yield on a U.S. Treasury constant maturity with a remaining term equal to the vesting period of the RSU grant.
	The weighted-average assumptions and valuation of the Company’s stock options were as follows:
			FISCAL YEARS ENDED APRIL 30
			2014				2013				2012
	Weighted-average fair value of grants	$	14.46			$	7.39			$	5.43
	Expected volatility		38.2	%			42.5	%			35.1	%
	Expected term in years		6.1				6.1				6.0
	Risk-free interest rate		1.59	%			1.09	%			2.24	%
	Expected dividend yield		0.0	%			0.0	%			2.0	%
	Stock Option Activity
	Stock options granted and outstanding under each of the Company’s plans vest evenly over a three-year period and have contractual terms of ten years. The exercise price of all stock options granted is equal to the fair market value of the Company’s common stock on the option grant date.
	The following table presents a summary of the Company’s stock option activity for the fiscal years ended April 30, 2014, 2013 and 2012 (remaining contractual term in years and exercise prices are weighted-averages):

	The aggregate intrinsic value in the previous table of the outstanding options on April 30, 2014 represents the total pre-tax intrinsic value (the excess, if any, of the Company’s closing stock price on the last trading day of fiscal 2014 over the exercise price, multiplied by the number of in-the-money options) of the shares of the Company’s common stock that would have been received by the option holders had all option holders exercised their options on April 30, 2014. This amount changes based upon the fair market value of the Company’s common stock.  The total fair value of options vested for the fiscal years ended April 30, 2014, 2013 and 2012 was $0.7 million, $1.2 million and $2.4 million, respectively.
	As of April 30, 2014, there was $0.8 million of total unrecognized compensation expense related to unvested stock options granted under the Company’s stock-based compensation plans. This expense is expected to be recognized over a weighted-average period of 1.7 years.
	Cash received from option exercises for the fiscal years ended April 30, 2014, 2013 and 2012, was an aggregate of $14.7 million, $5.9 million and $0.0 million, respectively.  The actual tax benefit realized for the tax deduction from option exercises of stock option awards totaled $2,011,000, $729,000 and $3,000 for the fiscal years ended April 30, 2014, 2013 and 2012, respectively.
	The following table summarizes information about stock options outstanding at April 30, 2014 (remaining lives in years and exercise prices are weighted-averages):

Restricted Stock Tracking Units:
During fiscal 2014, the Board of Directors of the Company approved grants of 9,486 cash-settled performance-based restricted stock tracking units (RSTUs) and 3,264 cash-settled service-based RSTUs for more junior level employees who previously received RSU grants under the Company’s shareholder approved plan.  Each performance-based RSTU entitles the recipient to receive a payment in cash equal to the fair market value of a share of the Company’s common stock as of the payment date if applicable performance conditions are met and the recipient remains continuously employed with the Company until the units vest.  The service-based RSTUs entitle the recipients to receive a payment in cash equal to the fair market value of a share of our common stock as of the payment date if they remain continuously employed with the Company until the units vest.  The RSTUs cliff-vest three years from the grant date.  Since the RSTUs will be settled in cash, the grant date fair value of these awards is recorded as a liability until the date of payment.  The fair value of each cash-settled RSTU award is remeasured at the end of each reporting period and the liability is adjusted, and related expense recorded, based on the new fair value.  The Company recognized expense of $78 thousand related to RSTUs for the fiscal year ended April 30, 2014.

Employee Benefit And Retirement Plans [Abstract]	'
Employee Benefit And Retirement Plans	'
	Note H – Employee Benefit and Retirement Plans
	Employee Stock Ownership Plan
	In fiscal 1990, the Company instituted the American Woodmark Investment Savings Stock Ownership Plan. Under this plan, all employees who are at least 18 years old and have been employed by the Company for at least six consecutive months are eligible to receive Company stock through a discretionary profit-sharing contribution and a 401(k) matching contribution based upon the employee's contribution to the plan.
	Beginning in fiscal 2013, discretionary profit-sharing contributions ranging from 0-5%, based on predetermined net income levels of the Company, may be made annually in the form of Company stock.  Prior to fiscal 2013, profit-sharing contributions in the form of Company stock were 3% of after-tax earnings, calculated on a quarterly basis.  The Company recognized expenses for profit-sharing contributions of $818,000 and $293,000 in fiscal years 2014 and 2013, respectively.  The Company did not make, or recognize any expenses for, discretionary profit-sharing contributions in fiscal 2012.
	Beginning in fiscal 2013, as part of the realignment of its retirement plans, the Company increased the match on 401(k) contributions in the form of Company stock to 100% of an employee’s annual contribution to the plan up to 4% of base earnings.  Prior to fiscal 2013, the Company matched 401(k) contributions in the form of Company stock at 50% of an employee's annual contribution to the plan up to 4% of base earnings for an effective maximum Company contribution of 2% of base earnings.  The expense for 401(k) matching contributions for this plan was $4,054,000, $2,547,000 and $1,284,000, in fiscal years 2014, 2013 and 2012, respectively.
	Pension Benefits
	The Company has two defined benefit pension plans covering many of the Company’s employees hired prior to April 30, 2012. These plans provide defined benefits based on years of service and final average earnings (for salaried employees) or benefit rate (for hourly employees).
	Effective April 30, 2012, the Company froze all future benefit accruals under the Company’s hourly and salaried defined benefit pension plans.
	Included in accumulated other comprehensive loss at April 30, 2014 is $42.6 million ($26.0 million net of tax) related to net unrecognized actuarial losses that have not yet been recognized in net periodic pension benefit costs. The Company expects to recognize $0.9 million ($0.5 million net of tax) in net actuarial losses in net periodic pension benefit costs during fiscal 2015.  The Company uses an April 30 measurement date for its benefit plans.
	The following provides a reconciliation of benefit obligations, plan assets and funded status of the Company’s non-contributory defined benefit pension plans as of April 30:
			30-Apr

	Actuarial Assumptions:  The discount rate at April 30 was used to measure the year-end benefit obligations and the earnings effects for the subsequent year. Actuarial assumptions used to determine benefit obligations and earnings effects for the pension plans follow:
		FISCAL YEARS ENDED APRIL 30
		2014		2013
	WEIGHTED-AVERAGE ASSUMPTIONS TO DETERMINE BENEFIT OBLIGATIONS
	Discount rate	4.56	%	4.21	%
		FISCAL YEARS ENDED APRIL 30
		2014		2013		2012
	WEIGHTED-AVERAGE ASSUMPTIONS TO DETERMINE NET PERIODIC PENSION BENEFIT COST
	Discount rate	4.21	%	4.66	%	5.66%/4.76%  1
	Expected return on plan assets	7.5	%	7.5	%	8	%
	Rate of compensation increase	*		*		4	%
	1 The discount rate was 5.66% from May 1, 2011 to December 31, 2011 and 4.76% from January 1, 2012 to April 30, 2012.  The rate changed during fiscal 2012 as a result of the required re-measurement of the Company's pension liability upon its decision to freeze its pension plans.
	*  The rate of compensation increase is not applicable for periods beyond April 30, 2012 because the Company froze its pension plans effective as of that date.
	In fiscal years 2014, 2013 and 2012, the Company determined the discount rate by referencing the Aon Hewitt AA Bond Universe Yield Curve.  The Company believes that using a yield curve approach accurately reflects changes in the present value of liabilities over time since each cash flow is discounted at the rate at which it could effectively be settled.
	In developing the expected long-term rate of return assumption for the assets of the defined benefit pension plans, the Company evaluated input from its third party pension plan asset managers, including their review of asset class return expectations and long-term inflation assumptions.  The Company also considered the related historical ten-year average asset returns at April 30, 2014.
	The Company amortizes experience gains and losses, as well as the effects of changes in actuarial assumptions and plan provisions, over the average remaining lifetime of the active participants.
	Contributions:  The Company funds the pension plans in amounts sufficient to meet minimum funding requirements under applicable employee benefit and tax laws plus additional amounts the Company deems appropriate.
	The Company expects to contribute $4.3 million to its pension plans in fiscal 2015.  The Company made contributions of $2.3 million and $4.9 million to its pension plans in fiscal 2014 and 2013, respectively.
	Estimated Future Benefit Payments: The following benefit payments, which reflect expected future service, are expected to be paid:
	FISCAL YEAR		BENEFIT PAYMENTS (in thousands)
	2015		$	4,719
2016			5,135

Investment Strategy:  The Company has established formal investment policies for the assets associated with its pension plans.  The objectives of the investment strategies include preservation of capital and long-term growth of capital while avoiding excessive risk.  Target allocation percentages are established at an asset class level by the Company’s Pension Committee.  Target allocation ranges are guidelines, not limitations, and the Pension Committee may approve allocations above or below a target range.
During a period of uncertainty in the equity and fixed income markets, the Pension Committee may suspend the Target Asset Allocation and manage the investment mix as it sees reasonable, prudent and in the best interest of the plans to better protect the value of the plan assets.
The Company’s pension plans’ weighted-average asset allocations at April 30, 2014 and 2013, by asset category, were as follows:
	PLAN ASSET ALLOCATION
	2014			2014			2013
30-Apr	TARGET			ACTUAL			ACTUAL
Equity Funds	50	%		50	%		50.2	%
Fixed Income Funds	50	%		50	%		49.8	%
Total	100	%		100	%		100	%
Within the broad categories outlined in the preceding table, the Company has targeted the following specific allocations as a percentage of total funds invested:  17% Capital Preservation, 33% Bond, 20% Large Capital Growth, 20% Large Capital Value, 6% Small Capital and 4% International.

	Note K -- Commitments and Contingencies
	Legal Matters
	The Company is involved in suits and claims in the normal course of business, including without limitation product liability and general liability claims, and claims pending before the Equal Employment Opportunity Commission. On at least a quarterly basis, the Company consults with its legal counsel to ascertain the reasonable likelihood that such claims may result in a loss. As required by ASC Topic 450, “Contingencies” (ASC 450), the Company categorizes the various suits and claims into three categories according to their likelihood for resulting in potential loss:  those that are probable, those that are reasonably possible and those that are deemed to be remote.  Where losses are deemed to be probable and estimable, accruals are made.  Where losses are deemed to be reasonably possible, a range of loss estimates is determined and considered for disclosure.  In determining these loss range estimates, the Company considers known values of similar claims and consultation with independent counsel.
	The Company believes that the aggregate range of loss stemming from the various suits and asserted and unasserted claims which were deemed to be either probable or reasonably possible was not material as of April 30, 2014.
	Product Warranty
	The Company estimates outstanding warranty costs based on the historical relationship between warranty claims and revenues. The warranty accrual is reviewed monthly to verify that it properly reflects the remaining obligation based on the anticipated expenditures over the balance of the obligation period. Adjustments are made when actual warranty claim experience differs from estimates. Warranty claims are generally made within two months of the original shipment date.
	The following is a reconciliation of the Company’s warranty liability:
			30-Apr

	Lease Agreements
	The Company leases certain office buildings, manufacturing buildings, service centers and equipment. Total rental expenses under operating leases amounted to approximately $8,005,000, $7,378,000 and $7,206,000, in fiscal years 2014, 2013 and 2012, respectively. Minimum rental commitments as of April 30, 2014, under noncancelable leases with terms in excess of one year are as follows:

	Related Parties
	During fiscal 1985, prior to becoming a publicly held corporation, the Company entered into an agreement with a partnership which includes certain former executive officers and current significant shareholders of the Company, including one current member of the Board of Directors of the Company, to lease the Company’s headquarters building which was constructed and is owned by the partnership. The Company has subsequently renewed this lease in accordance with Company policy and procedures which includes approval by the Board of Directors. As of April 30, 2014, the Company is in the fourth year of the latest five-year renewal period, which expires in 2016. Under this agreement, rental expense was $470,000, $461,000 and $460,000, in fiscal years 2014, 2013 and 2012, respectively. Rent during the remaining term of approximately $927,000 (included in the preceding table) is subject to annual increases of 2%  through the remaining term of the lease.

	Credit is extended to customers based on an evaluation of each customer's financial condition and generally collateral is not required. The Company's customers operate in the new home construction and home remodeling markets.
	The Company maintains an allowance for bad debt based upon management's evaluation and judgment of potential net loss. The allowance is estimated based upon historical experience, the effects of current developments and economic conditions and of each customer’s current and anticipated financial condition. Estimates and assumptions are periodically reviewed and updated. Any resulting adjustments to the allowance are reflected in current operating results.
	At April 30, 2014, the Company's two largest customers, Customers A and B, represented 21.0% and 21.4% of the Company's gross customer receivables, respectively. At April 30, 2013, Customers A and B represented 21.1% and 21.1% of the Company’s gross customer receivables, respectively.

	The Company utilizes the hierarchy of fair value measurements to classify certain of its assets and liabilities based upon the following definitions:
	Level 1 – Investments with quoted prices in active markets for identical assets or liabilities.  The Company’s cash equivalents are invested in money market funds, mutual funds and United States Treasury instruments.  The Company’s mutual fund investment assets represent contributions made and invested on behalf of the Company’s named executive officers in a supplementary employee retirement plan.
	Level 2 – Investments with observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.  The Company has no Level 2 assets or liabilities.
	Level 3 – Investments with unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.  The Company has no Level 3 assets or liabilities.
	The following table summarizes the fair value of assets that are recorded in the Company’s consolidated financial statements as of April 30, 2014 and 2013 at fair value on a recurring basis:

Restructuring Charges	'
	Note N -- Restructuring Charges
	In the third quarter of fiscal 2012, the Company announced a restructuring initiative (“2012 Restructuring Plan”) that committed to the closing of two of the Company’s manufacturing plants located in Hardy County, West Virginia and Hazard, Kentucky, offering its previously idled plant in Tahlequah, Oklahoma for sale, and realigning its retirement program, including freezing the Company’s defined benefit pension plans.  Operations ceased at the Hazard plant in April 2012 and at the Hardy County plant in May 2012.   The 2012 Restructuring Plan was adopted to reduce costs and increase the Company’s capacity utilization rates.
	In the fourth quarter of fiscal 2009, the Company announced a restructuring plan (“2009 Restructuring Plan”) to close two of its manufacturing plants, located in Berryville, Virginia and Moorefield, West Virginia and suspend operations in a third manufacturing plant located in Tahlequah, Oklahoma.  These actions were completed during the first quarter of fiscal 2010.  These initiatives were intended to increase the Company’s capacity utilization rates and decrease overhead costs.  In addition to these initiatives, the Company made other staffing reductions during the fourth quarter of fiscal 2009.
	During fiscal years 2014, 2013 and 2012, the Company recognized total pre-tax restructuring charges for both the 2012 Restructuring Plan and the 2009 Restructuring Plan of $(234,000), $1.4 million and $16.3 million, respectively.  The Company recognized recurring operating costs for the facilities closed as part of the 2012 Restructuring Plan of $0.3 million in fiscal 2014.  These costs will continue until the remaining closed plant is sold.
	The Company has one manufacturing plant classified as held for sale, which was closed in the 2012 Restructuring Plan.  During the fourth quarter of fiscal 2014, the Company sold its closed plant located in Hazard, Kentucky and recognized a gain of $0.3 million on the sale.  The gain was included in restructuring charges on the Company’s statements of operations.  The Company believes that the remaining $1.0 million net book value of the property classified as held for sale is fully recoverable.  This asset is included in Other Assets on the Company’s balance sheet at April 30, 2014.

Summary_Of_Significant_Account1

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Apr. 30, 2014
Summary Of Significant Accounting Policies [Abstract]	'
Principles Of Consolidation And Basis Of Presentation	'
	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	'
	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:  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:  Advertising costs are expensed as incurred. Advertising expenses for fiscal years 2014, 2013 and 2012 were $30.4 million, $36.5 million and $37.4 million, respectively.
Cash And Cash Equivalents	'
	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 $38.9 million at both April 30, 2014 and 2013.
Inventories	'
	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:  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	'
	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 2014, 2013 and 2012, the Company concluded no impairment existed, except for impairments related to restructuring activities.
Promotional Displays	'
	Promotional Displays:  The Company invests in promotional displays in retail stores to demonstrate product features, product and quality specifications and 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 2014, 2013 and 2012 was $3.7 million, $4.0 million and $5.6 million, respectively, and is included in selling and marketing expenses.
Income Taxes	'
	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	'
	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	'
	Stock-Based Compensation:  The Company recognizes stock-based compensation expense based on the grant date fair value over the requisite service period.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements:  In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2013-02, “Comprehensive Income (Topic 220): Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component.  In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period.  The ASU does not change the current requirements for reporting net income or other comprehensive income in financial statements.  The Company adopted this guidance effective May 1, 2013 with no significant impact on the Company’s results of operations or financial position.
Use Of Estimates	'
	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	'
	Reclassifications:  Certain reclassifications have been made to prior period balances to conform to the current year presentation, including between components of property, plant and equipment.
