[1] The net investment loss per unit is calculated by dividing the net investment loss by the average number of Class A, B or I Units outstanding during the period. Gain (loss) from trading is a balancing amount necessary to reconcile the change in net asset value per unit with the other per unit information. Such balancing amount may differ from the calculation of gain (loss) from trading per unit due to the timing of trading gains and losses during the period relative to the number of units outstanding.

[2] Ratios have not been annualized.

[3] The net investment loss includes interest income and excludes net realized and net change in unrealized gain (loss) from trading activities as shown in the consolidated statements of operations. The total amount is then reduced by all expenses, excluding brokerage commissions, which are included in net trading gain (loss) in the consolidated statements of operations. The resulting amount is divided by the average net asset value for the period.

[4] Ratios have been annualized.

[5] Ratio excludes Trading Advisor incentive fees and General Partner 1% allocation.
