Patricio Contesse, SQM's Chief Executive Officer, stated, "Following the strong results posted in the first half of 2012, we are pleased to announce our financial results achieved during the third quarter. Margins have been driven primarily by increased prices in iodine and by increased sales volumes in the potassium, lithium, and industrial chemical business lines." Mr. Contesse continued, "These strong results though, pose a new set of challenges for the next months. On one hand, potash price environment has been relatively unstable in the past weeks and difficult to predict for the near future. On the other hand, European economy slowdown is starting to show some effect in volumes across all our business lines. However, our unique commercial flexibility and operational synergies will allow us to continue maintaining our competitive advantage and to react and benefit to changing market needs."
