Bank of America - CEO Brian Moynihan earned $12.1 million in 2012, up 73 percent from the prior year, due to increased stock awards. His salary was $950,000 with no cash bonus, with an increase to $1.5 million for 2013.

Apple - The company may lose its case against investor David Einhorn, though a judge did not make an immediate ruling on Einhorn's attempt to halt a vote on a new procedure for issuing preferred stock shares. He did say he is likely to rule in Einhorn's favor when the ruling is handed down.

Starwood Hotels - Jefferies is downgrading the stock to "hold" from "buy," saying it likes management's current strategy, but noting that the benefits from that strategy are already reflected in the stock's price.

Analog Devices - Analog earned $0.44 per share, excluding certain items, for its fiscal first quarter, one cent below estimates, with revenue also falling short. The chipmaker continued to see weaker demand, especially in its automotive business. It raised its quarterly dividend to $0.34 per share from $0.30.

The provider of nutrition products is at the center of a battle between investor Bill Ackman, who has a large short position and calls the company a "pyramid scheme," and Carl Icahn, who has taken a 13 percent stake. Herbalife also said the U.S. Securities and Exchange Commission has requested information regarding the company's business and financial operations.
