Renault CEO Carlos Ghosn publicly apologized for wrongly accusing three of his managers of corporate espionage. The automaker fired the men in January, claiming they had taken payments from Chinese firms for company secrets. After French police discredited the claims this month, Ghosn gave up his 2010 bonus and offered to reinstate and compensate the managers. COO Patrick Pélata and other executives involved in the mishandled probe will also return their bonuses. The French government, which owns a 15 percent stake in Renault, is demanding an independent inquiry.

HP also plans to create a cloud app store aimed at both businesses and consumers, seeing this as a way to unite its printer, PC, and infrastructure equipment empires. So far, the strategy is long on vision and thin on details. Still, it marks a major shift in thinking from HP's previous CEO Mark Hurd, who largely ignored the rise of cloud services.

American International Group: A Vote of Confidence in Japan

Despite the devastation in Japan following the Mar. 11 earthquake, AIG (AIG) says it remains committed to its Feb. 10 agreement to buy the 45 percent of Osaka-based Fuji Fire & Marine Insurance it doesn't already own. The $565 million offer will close on Mar. 24. Standard & Poor's (MHP) on Mar. 15 changed its outlook for Japan's non-life insurers to negative. Insurers may face claims of as much as $35 billion, which would make Japan's disaster the second-costliest ever, after Hurricane Katrina's $50 billion bill, according to risk consultants AIR Worldwide.
