A worker watches aluminium ingots on a conveyor belt at the Rusal Khakassia aluminium smelter outside the town of Sayanogorsk, Russia, September 3, 2015. Russia's Rusal has decided to delay a decision on its possible first dividend since listing five years ago though its second-quarter core profit more than doubled thanks to cost cuts and a weaker rouble.
