| Capital Stock [Table Text Block] | The Fund offers four separate classes of shares of beneficial interest designated as Class I Shares, Class D Shares, Class S Shares and Class T Shares. Each class of Shares is subject to different fees and expenses. The minimum initial investment in Class I Shares by an investor in the Fund is $1.0 million. The minimum initial investment in Class D Shares, Class S Shares and Class T Shares by an investor is $50,000. The minimum initial investment may be reduced at the Adviser's discretion. Investors purchasing Class S Shares and Class T Shares may be charged a sales load up to a maximum of 3.50% and investors purchasing Class D Shares may be charged a sales load up to a maximum of 1.50%. Investors purchasing Class I Shares are not charged a sales load. The Fund accepts initial and additional purchases of Shares as of the first business day of each calendar month at the Fund’s then-current NAV per share (determined as of the close of business on the last business day of the immediately preceding month). The following table summarizes the Capital Share transactions for the year ended March 31, 2024 and the period ended March 31, 2023: For the Year Ended For the Period Ended Shares Dollar Amounts Shares Dollar Amounts Class I Proceeds from shares issued 5,807,404 $ 193,234,285 6,167,112 $ 161,808,088 Reinvestment of distributions — — — — Repurchase of shares (14,118 ) (516,166 ) — — Exchange of shares 3,215 108,765 — — Net increase (decrease) 5,796,501 $ 192,826,884 6,167,112 $ 161,808,088 Class D Proceeds from shares issued 62,190 $ 2,050,000 25,073 $ 743,000 Reinvestment of distributions — — — — Repurchase of shares — — — — Exchange of shares 660 17,815 — — Net increase (decrease) 62,850 $ 2,067,815 25,073 $ 743,000 Class S Proceeds from shares issued 1,699,031 $ 58,938,930 1,000 $ 25,000 Reinvestment of distributions — — — — Repurchase of shares — — — — Exchange of shares (1,491 ) (52,236 ) — — Net increase (decrease) 1,697,540 $ 58,886,694 1,000 $ 25,000 Class T Proceeds from shares issued 4,397 $ 142,375 1,000 $ 25,000 Reinvestment of distributions — — — — Repurchase of shares — — — — Exchange of shares (2,401 ) (74,344 ) — — Net increase (decrease) 1,996 $ 68,031 1,000 $ 25,000 * The Fund commenced operations on November 1, 2022. The Adviser intends to recommend to the Board, subject to the Board’s discretion, that the Fund offer a quarterly share repurchase program where the total aggregate amount of Share repurchases will be up to 2.50% of the Fund’s outstanding Shares each quarter. In the event that Shareholders, in the aggregate, submit for repurchase more than the number of Shares that the Fund will offer to repurchase, the Fund may repurchase the Shares on a pro rata basis, which may result in the Fund not honoring the full amount of a Share repurchase requested by a Shareholder. Any repurchase of Shares which have been held for less than one year by a Shareholder, as measured through the date of redemption, will be subject to an early repurchase fee equal to 2.00% of the NAV of the Shares repurchased by the Fund. The Fund has no obligation to repurchase Shares at any time; any such repurchases will only be made at such times, in such amounts and on such terms as may be determined by the Board of Trustees, in its sole discretion. |
