EMPLOYEE 401(k) PLANS [Abstract]
EMPLOYEE 401(k) PLANS	8. EMPLOYEE 401(k) PLANS The Company maintains a 401(k) plan (the "Plan"), qualified under the Internal Revenue Code, in which all eligible employees, as defined in the Internal Revenue Code, may elect to participate. Under the Plan, employees may voluntarily make tax-deferred contributions of up to 15% of their compensation to a trust, which provides the participant with various investment alternatives. In addition, for each fiscal year, the Company, at the discretion of the Board of Directors, may contribute an amount of Company stock with a fair market value that does not exceed 5% of the annual compensation of all participants in the Plan. The Company made no contributions during the years ended April 30, 2013 or 2012. The Company also maintains another 401(k) plan in which long-tenured employees maintain accounts; however, the Company and its employees are no longer contributing to this plan.

The entire disclosure for pension and other postretirement benefits.
