[3] The Total Return for the three months ended March 31, 2024 and 2023 was calculated by taking total income from investment operations for the period divided by the weighted average capital contributions from the Members during the period. The return does not reflect sales load and is net of management fees and expenses.

[4] The Internal Rate of Return (“IRR”) since inception for the Common Unitholders, after management fees, financing costs and operating expenses, but before incentive fees is 11.32% through March 31, 2024. The IRR since inception for the Common Unitholders, after management fees, financing costs and operating expenses is 9.61% through March 31, 2024. The IRR is computed based on cash flow due dates contained in notices to Members (contributions from and distributions to the Common Unitholders) and the net assets (residual value) of the Members’ Capital account at period end. The IRR is calculated based on the fair value of investments using principles and methods in accordance with GAAP and does not necessarily represent the amounts that may be realized from sales or other dispositions. Accordingly, the return may vary significantly upon realization.

[5] Annualized.
