Economic consequences of privatization and liberal institutions have meant changes in taxation to attract foreign investment. Colombia will lose another $800 million over the next 90 years that Glencore International operates in El Cerrejon Zona Media, if the company continues to produce coal at a rate of 5 million tons/year, because of the reduction of the royalty tax from 10-15% to .04%. If the company, as is plausible, doubles or triples its production, the losses will be proportionally greater. The operational losses from the three large mining projects (El Cerrejon, La Loma, operated by Drummond, and Montelíbano, which produces ferronickel) for Colombia to more than 12 billion.
