"One of the nation's largest unions is calling for 29 financial-services companies to investigate more than $5 billion in pay given to the firms' five highest-paid executives," according to Dow Jones Newswires. "The pension funds of the Service Employees International Union wants the companies' boards to review whether the compensation was 'tied to derivatives and other questionable instruments that are now worthless.'"
