I now leave you with our COO, Patricio de Solminihac, for brief comments before we move to Q&A.
Patricio de Solminihac T. - EVP and COO: Good morning and thank you for joining the SQM earning conference call. I will start with a brief introduction before I open up the lines for questions. For the first quarter, gross profit was slightly better than both the first and the last quarter of 2012. Having said this, we expect the remainder of 2013 to be lower than the first part of this year.
In the SPN business line, we saw increased demand during the first quarter of 2013. During this strong quarter, our volumes increased over 35% when compared to the relatively weak first quarter of 2012. Most product within the SPN business line saw higher sales volume during the first three months of 2013, which contribute to our increased revenues. However, as anticipated, average price for the business line fell about 3% when compared to the fourth quarter of 2012.
On the potash side, it is anticipated that the total market demand will exceed market demand seen in 2012, although we're seeing the impact of lower prices. We believe this market condition will continue throughout the years as market demand is expected to surpass 54 million metric ton during 2013, an increase of about 8% over last year.
As expected, the first quarter of 2013 showed strong sales volume of potassium chloride; volumes increased over 25% when compared to the first quarter of the previous year. We expect our total sales volumes of MOP and SOP fertilizers from the Salar de Atacama to be over 20% higher than the sales volumes seen last year.
