Rio will announce its full year profit and dividend on February 11, and Citi analyst Clarke Wilkins said he did not think Rio's dividend was at risk of being cut. "While we have halved BHP's [expected] dividend due to concerns over BHP's balance sheet we think that Rio still has more levers to pull and at this stage do not see a significant risk to the forecast dividend of US$2.28 per share," he said in a note to clients. S&P reaffirmed Fortescue Metals Group's BB credit rating on Wednesday, and kept the iron ore miner's outlook on negative.
