10. BENEFIT PLAN

10. BENEFIT PLAN

During fiscal year 1997, we adopted a 401(k) benefit plan (the “Plan”) for all full-time employees who are at least the age of 21 and have three or more months of continuous service. The Plan provides for employee contributions of up to 100% of their compensation on a tax deferred basis up to the maximum amount permitted by the Internal Revenue Code. We are not required to make matching contributions under the Plan and we have made no matching contributions to the Plan since its inception through December 2009. Effective January 2010, we voluntarily agreed to match 50% of employee contributions of up to the first 6% of a participant’s annual salary for all Plan contributions, subject to certain IRS limitations. Under the Plan, each participating employee is fully vested in his or her contributions to the Plan and our contributions to the Plan will fully vest after six years of service. The expense related to our matching contributions to the Plan was $284,000, $232,000 and $210,000 for the fiscal years ended April 30, 2013, 2012 and 2011, respectively.
