NEW YORK (AP) — Offshore driller Transocean Ltd. said Thursday that Ricardo H. Rosa is stepping down as chief financial officer after just two years in the position and will retire from the company in April.
The company did not explain why Rosa, 55, is leaving his post effective Monday. The Transocean veteran previously served as senior vice president of the company's Europe and Africa unit and of its Asia and Pacific unit, as well as in a variety of international positions in finance over two decades. He took over as CFO in May 2009 when Gregory L. Cauthen retired.
Until a permanent successor is found, Cauthen, 54, will return to step in as CFO on an interim basis.
Transocean owned the Deepwater Horizon drilling rig that exploded and sank in the Gulf of Mexico in April 2010, killing 11 workers and causing the nation's worst offshore oil spill. Transocean, well operator BP PLC and other companies have filed lawsuits blaming each other for the incident.
Transocean shares fell 82 cents, or 2 percent, to close earlier at $39.73. The stock was little changed in after-hours trading.
