(1) Per share data may be rounded in order to recompute the ending net asset value per share.

(2) The per share data was derived by using the weighted average shares outstanding during the applicable period.

(3) The per share data for distributions declared reflect the actual amount of distributions declared per share during the applicable period.

(4) The amount shown is the balancing amount derived from the other figures in the schedule. The amount shown for a share outstanding throughout the period may not agree with the change in the aggregate gains and losses in Infrastructure Assets for the period because of the timing of sales of the Company’s shares in relation to fluctuating market values for the portfolio.

(5) Actual results may not be indicative of future results. Additionally, an individual Shareholder’s ratios may vary from the ratios presented for a share class as a whole.

(6) Weighted average net assets during the applicable period are used for this calculation.

(7) Ratios presented before accounting for the accrual of the Performance Participation Allocation.

(8) Ratios presented after accounting for the accrual of the Performance Participation Allocation.

(9) Ratios presented after expenses reimbursed and/or recouped by Manager.

(10) The Total return is calculated for each share class as the change in the net asset value for such share class during the period plus any distributions per share declared in the period, and assumes any distributions are reinvested in accordance with the Company’s distribution reinvestment plan. Amounts are not annualized and are not representative of total return as calculated for purposes of the Performance Participation Allocation as described in “Note 6. Related Party Transactions.” The Company’s performance changes over time and currently may be different than that shown above. Past performance is no guarantee of future results. Investment performance is presented without regard to sales load that may be incurred by Shareholders in the purchase of the Company’s shares.
