A Delaware bankruptcy judge has ordered Yucaipa Cos. to turn over information about director compensation, investments and employee performance reviews, ruling it is relevant to claims that Allied Systems Holdings suffered from breaches of fiduciary duties by the private equity firm.

U.S. Bankruptcy Judge Christopher S. Sontchi of the District of Delaware sided with the committee of unsecured creditors, which argued Yucaipa, with the help of Allied's board, took over Allied's debt for its own benefit.

The committee said the directors' compensation documents and informal communications, such as emails, are relevant to its inquiry surrounding alleged good faith and fair dealings by Yucaipa.
