In a prepared statement, the 63-year-old Mr. McColl said he was happy to stay longer than planned because he and other BankAmerica executives are "committed to working together to build America's bank. This will allow us to keep our team together." R. Harold Schroeder, an analyst at Keefe, Bruyette & Woods, said the action was not surprising. "There has been enough turmoil that I'm sure at least several of the board members would feel more comfortable not changing captains in mid- storm," Mr. Schroeder said. BankAmerica's stock fell $5.875 on Oct. 14, the day of its earnings announcement, to $48.0625. It closed at $54.875 Wednesday, up 93.75 cents. Also Wednesday, the BankAmerica board voted to increase the company's quarterly dividend by 7 cents to 45 cents per share. The dividend is payable Dec. 23 to shareholders of record Dec. 4. The board also declared a $1.75 cash dividend and a 62.5 cent- dividend on two preferred stock issues.
