We have improved our method for quality adjusting China delivered iron ore costs. We are now using value in use (VIU) adjustments where we adjust costs for iron silica and alumina content as well as lump and pellet premia. In the past we adjusted costs based on iron content alone. The change in methodology has led to a US$3/dmt fall in the weighted average North China delivered quality adjusted cost from last quarter to US$32.77/dmt. Under our previous methodology average quality adjusted China delivered costs would have increased by US$0.30/dmt this quarter mostly because of slightly higher sea freight costs.
