OCI (XAMS:OCI) (-21%; -0.9%), a global fertilizer and chemical producer, was the primary detractor from the Fund’s strong return. The stock fell early in the quarter, in line with a decline in the underlying urea commodity price which recovered somewhat by quarter-end. Global excess supply should diminish as nitrogen fertilizer demand grows approximately 2% per year while no additional plant capacity is scheduled for at least five years out. Uncertainty around OCI’s planned sale of its U.S. and European assets to CF Industries also weighed on the stock. A major hurdle to the deal was removed in mid-March, when OCI announced that Consolidated Energy Limited would jointly invest in the methanol plant, Natgasoline, which would fall outside of the scope of the assets going to CF. OCI is trading at a steep discount to our appraisal and even more cheaply assuming the CF deal closes in the second quarter of 2016 as planned.
