[1] The amounts reported for a Unit outstanding may not accord with the change in aggregate gains and losses on investments for the period due to the timing of Unit transactions in relation to the fluctuating fair values of the Fund’s investments.
[2] Percentage is not annualized.
[3] Total return is calculated for each Unit class as the change in the net asset value per each Unit class during the period, plus any distributions per Unit declared in the period, and assumes any distributions are reinvested in accordance with the Fund’s distribution reinvestment plan.
[4] Ratio does not include the effects of any Performance Participation Allocation.
