The Labor Department has ordered Columbus-based Clark Graphics and owners Mary and James Clark to restore more than 500-thousand dollars to a pair of employee retirement plants. The Department sued the company for violations of the Employee Retirement Income Security act, alleging insufficient oversight and mishandling of the plans. The Department also says Marcia Dowdell, who administered the retirement plans, must make restitution.
