A coalition of gold investors, including firms backed by billionaires John Paulson and Naguib Sawiris, is urging changes at miners as performance “continues to fall short” in some areas even as prices rise.

In an open letter to the mining industry, prominent gold investors including money managers at Franklin Templeton, CI Investments and members of the Shareholders’ Gold Council are targeting issues including executive compensation and directors who don’t have enough skin in the game because they don’t hold a meaningful amount of shares in the firms they represent. The signatories offered 16 suggestions to better align the interest of managers, boards and shareholders.
