[1] Interest income and expenses per unit are calculated by dividing these amounts by the average number of units outstanding during the period. The net gain/(loss) on investments, net of non-controlling interests is a balancing amount necessary to reconcile the change in net asset value per unit with the other per unit information.
[2] Expense ratios do not include management and incentive fees charged at the Galaxy Plus entities. The ratios would have been higher had those expenses been included. The impact of those fees is included in the total return.
[3] Expense ratios do not reflect interest allocated to the Managing Owner as such expenses are not included in the consolidated statements of operations of the Series.
[4] Impact of incentive fee computed using average net assets, otherwise computed using average units outstanding during the period prior to the effects of any non-controlling transactions. An owner’s total returns may vary from the above returns based on the timing of contributions and withdrawals.
