[1] Based on change in net asset value per Unit except for Class D Units.

[3] Does not include the expenses of the Trading Companies in which the Partnership invests.

[4] The increase in Class D’s net income allocation, while incurring a net loss per unit for the quarter ended September 30, 2012, is due to the timing of redemptions of units throughout the quarter.

[5] This amount represents March 1, 2013, net asset value per Unit prior to conversion from Class D to Class Z Units. There were no Class D Units outstanding at September 30, 2013.
