A.D. Marble became an Employee Stock Ownership Plan (ESOP) company on April 1, 2002 when Anne D. Marble decided to reward those current employees for helping the company grow, while developing a succession plan for the company.

What is ESOP?
An ESOP is a tax-qualified retirement benefit plan for employees, which turns A.D. Marble employees into owners of stock in the company. This plan is 100 percent company funded (employees do not make contributions), and the stock is not publicly traded.

What does it mean?
When you join A.D. Marble, you become an ESOP participant. You become eligible for allocation of ESOP shares following your first 1,000 hours within a fiscal year. You become vested in those shares (20 percent) following two years of employment, and become 100 percent vested after six years of service.

ESOP companies have traditionally fared better than non-ESOP companies, as employees truly benefit directly from their productivity and the growth of the business. As a result, ESOPs have greater employee morale and experience less turnover. For more information about ESOPs, their benefits, and local chapter events, visit The ESOP Association’s website.
