In a statement quoted by Bloomberg, a Moody's representative said, "[t]he negative outlook assigned to Gold Fields Ltd. (GFI)'s ratings is primarily driven by the near-term deterioration of free cash flow and higher reliance of cash flows from its operations in Ghana in the short to medium term, until the South Deep project is complete and can contribute towards healthy positive free cash flows." Gold Field's share price is trading $0.04 lower, at $11.33.
