| http://www.w3.org/ns/prov#value | - Assuming Vale's average sales price for iron ore of $100/ton in 2012 and $90/ton in 2013 and 100% of its capital expenditures, including all projects approved and undergoing, we expect Vale to maintain comfortable credit metrics for the rating category--such as total adjusted net debt to EBITDA below 1.5x in the next two years.
