Representatives of mutual fund giant Fidelity Investments tried to impede two shareholders from voting against the company's board in a proxy contest over a human rights issue, the shareholders said. Shareholders of nine funds will vote on Friday on a resolution urging Fidelity to bar holdings in companies that "contribute to genocide or crimes against humanity.”...Only a "negligible" number of shareholders have complained about the voting, said a Fidelity spokesman...[T]he two shareholders say they received calls from employees of Fidelity's proxy-solicitation firm, D.F. King & Co, who made it hard for them to record their votes in favor of the proposal by phone. [also refers to PetroChina]
