Our investigation concerns whether Transocean, which permitted investment of Company stock in Transocean's retirement plans, breached its fiduciary duty to plan participants by failing to disclose known hazards associated with its use of certain blowout preventers on ultra-deepwater drilling engagements from investors in its 2009 and 2010 statements. These actions made investing in Transocean stock by plan participants an imprudent investment.
