Goldman Sachs Group Inc., the sixth-largest U.S. bank by assets, can't omit a shareholder proposal calling for an independent chairman from its annual meeting, the Securities and Exchange Commission said. The SEC's Office of Chief Counsel said it didn't agree with Goldman Sachs's claim that the proposal was "inherently vague or indefinite," according to a letter dated March 5 that was posted today on the agency's website. The proposal says that the bank must appoint a chairman that's independent of management whenever possible.
