[1] Net investment income (loss) per Redeemable Unit is calculated by dividing the interest income less total expenses by the average number of Redeemable Units outstanding during the period. The net realized and unrealized gains (losses) per Redeemable Unit is a balancing amount necessary to reconcile the change in net asset value per Redeemable Unit with the other per unit information.
[2] Annualized (except for incentive fees).
[3] Interest income less total expenses.
