The following financial highlights show the Trust’s financial performance of the Trading units by class for the three and six month periods ended June 30, 2015, and 2014, respectively.  Total return is calculated as the change in a theoretical beneficial owner’s investment over the entire period, and is not annualized.  Total return is calculated based on the aggregate return of the Trust’s Trading units taken as a whole.  As of June 30, 2015, no Class D units had been sold and, therefore, the Trust’s financial performance with respect to the class D units is not reflected below.
