JPMorgan Chase (JPM) will improve risk management of its Chief Investment Office, the unit that racked up more than $2 billion of trading losses, while avoiding big bets on derivative and private-equity investments, The Wall Street Journal reported, citing people close to the bank. But the CIO intends to stick with a strategy permitting a wide variety of other, potentially risky investments, the people told the newspaper.

An internal review by senior bankers of what went wrong isn't complete, but early conclusions focus on improving the unit's risk-management processes rather than curtailing investment options or broadly reining in risk, people close to the matter said.

Research In Motion (RIMM), the BlackBerry maker, could split its business in two by separating its handset manufacturing unit from its messaging network, according to The Sunday Times, which didn't cite sources.

RIM may break off the handset division into a separate listed company or try to sell it, the British newspaper said. Amazon (AMZN) or Facebook (FB) were listed as potential buyers, The Sunday Times said.

Anheuser-Busch InBev (BUD), the world's biggest brewer, is in talks to buy the 50% of Corona beer maker Grupo Modelo that it doesn't already own, Reuters reported, citing a person familiar with the matter. The deal could be valued at more than $10 billion, Reuters said.
