Capital Stock [Table Text Block]					4. CAPITAL SHARES The Fund currently offers its Shares on a continuous basis and was granted Multi-Class Exemptive Relief by the SEC that permits the Fund to issue multiple classes of shares and to impose asset-based distribution fees and early-withdrawal fees. In addition to the Class I Shares, Class D Shares, Class S Shares, and Class T Shares, the Fund may offer additional classes of shares in the future. The Shares are continuously offered each month at an offering price equal to NAV per share (plus an applicable front-end sales load, where relevant), which is calculated: (i) as of the close of business on the last business day of each month; (ii) on each date that Shares are to be repurchased in connection with the Fund's offer to purchase Shares; and (iii) at such other times as the Board shall determine. The differences among the Shares relate to front-end sales loads and ongoing distribution and shareholder servicing fees. No front-end sales load or distribution and shareholder servicing fees are paid with respect to Class I Shares. The Class D Shares and the Class S Shares are each subject to a front-end sales load of up to 2.00% and 3.50%, respectively. Investors purchasing Class T Shares may be charged a sales load of up to 3.00% and a maximum dealer fee of 0.50% of the investment amount, for a total front-end sales load of up to 3.50%. Holders of the Shares have equal rights and privileges with each other, except with respect to front-end sales loads and certain ongoing distribution and shareholder servicing fees. For the six months ended June 30, 2024, distribution and shareholder servicing fees totaled $834,000 for Class S Shares. Distribution and shareholder servicing fees for Class D Shares were less than $1,000 for the period from March 1, 2024 (inception date) to June 30, 2024. At June 30, 2024, 10.56% of the shares of the Fund were owned by Brookfield and its affiliates.
