(1)The per share data for distributions was derived by using the actual shares outstanding at the date of the relevant transaction (refer to Note 4).
(2)The per share data was derived by using the weighted average shares outstanding during the applicable period.
(3)The amount shown at this caption is the balancing amount derived from the other figures in the table. The amount shown at this caption for a share outstanding throughout the period may not agree with the change in the aggregate gains and losses in investments for the period because of the timing of sales of Series I shares in relation to fluctuating market value for the portfolio.
(4)Actual results may not be indicative of future results. Additionally, an individual shareholder's ratio may vary from the ratios presented for a share class as a whole.
(5)The ratios were derived using the simple average net assets during the applicable period.
(6)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 our distribution reinvestment plan. The Series I 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 Series I shares.

(1)The per share data for distributions was derived by using the actual shares outstanding at the date of the relevant transaction (refer to Note 8).
(2)The per share data was derived by using the weighted average shares outstanding during the applicable period.
(3)The amount shown at this caption is the balancing amount derived from the other figures in the table. The amount shown at this caption for a share outstanding throughout the period may not agree with the change in the aggregate gains and losses in investments for the period because of the timing of sales of Series II shares in relation to fluctuating market value for the portfolio.
(4)Actual results may not be indicative of future results. Additionally, an individual shareholder's ratio may vary from the ratios presented for a share class as a whole.
(5)The ratios were derived using the simple average net assets during the applicable period.
(6)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. Amounts are not representative of total return as calculated for purposes of the Performance Participation Allocation as described in Note 6. The Series II 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 Series II shares.
(7)Class I shares and Class J shares were first issued on June 1, 2026 and May 1, 2026, respectively. Amounts presented are for the period from issuance date through June 30, 2026. The ratios of expense and net investment income (loss) and the total return for these share classes have not been annualized.
