"While the most recent suit covers much of the same ground as the earlier litigation ... it includes as a defendant GreatBanc Trust Company, who was appointed independent fiduciary to act as a named fiduciary for limited purposes in connection with the ESOP provisions of the plan in 2012.... The suit also highlights the role of defendant Hope A. Hardison, Senior Executive VP, Chief Administrative Officer and HR Director, who 'ultimately oversaw both the Plan and the termination of thousands of employees as a direct result of fraud surrounding the Company's primary business strategy,' according to the complaint."
