The following post comes to us from Dr. John Montgomery, Senior Vice President with NERA Economic Consulting, and is based on a NERA publication by Dr. Montgomery which previously appeared in the July, August, and September 2011 issues of the Employment Law Strategist.
In the past decade, numerous lawsuits have been brought under ERISA against the fiduciaries and sponsors of 401(k) and other defined contribution retirement plans. Many of these lawsuits have been pled as class actions on behalf of all or many participants of the plan. The most common lawsuits have involved declines in the value of employer stock offered in the plans and allegations that decisions to maintain employer stock in the plans were imprudent. There have also been some lawsuits over other investment options, as well as lawsuits over the management of collateral from securities lending programs run by plan trustees. Another substantial category of litigation has involved allegations of excessive fees. Many of these cases, both investments and fees, have also involved allegedly inadequate disclosure of information to plan participants.
Economic analysis plays an important role in many of these cases. The purpose of this paper is to discuss some of the important economic issues that arise in ERISA litigation, both in establishing liability and in calculating damages.
