In July 2012, the DOL filed suit against Metavation, a Revstone subsidiary, in U.S. District Court, Eastern District of Kentucky, alleging Hofmeister and plan fiduciaries allowed $34.6 million in prohibited loans from two retirement plans.

In March 2013, the Pension Benefit Guaranty Corp. announced it was taking over the two Metavation plans, the Hillsdale Salaried Pension Plan, and the Hillsdale Hourly Pension Plan, according to PBGC's website.

Less than three months later, the DOL filed another suit in Kentucky federal court, alleging more breeches against defined benefit plans of Iowa-based Fairfield Castings, and Michigan-based Fourslides Inc., both Revstone companies.

So far, the DOL has been able to recover $12 million. Previous judgments have been issued against William Tweardy and Nelson Clemmens, members of the investment committee for Metavation and Fairfield pension plans.

All of the suits name Bernard Tew, and his advisory companies Bluegrass Investment Management and Tew Enterprises, as defendants, according to a release from the DOL.

The DOL's investigation has found that among other prohibited transactions, the pilfered pension assets went to pay excessive fees to Tew's provider companies.

Commenting on the most recent judgment, Phyllis Borzi, Assistant Secretary of Labor for Employee Benefits Security, said, "this order marks another step in recovering plan assets, but importantly, it keeps Hofmeister away from benefits plans entirely."

In February 2014, the PBGC reached a settlement agreement with Revstone and a bankruptcy court, securing as much as $95 million in assets as the company moves through liquidation.

For its part, the DOL is continuing to pursue judgments in ongoing litigation, according to a statement from the agency.
