[1] Net Asset Value Per Unit (accrual base) equates to the aggregate of the Total Members' Capital and Common Unitholders' undrawn commitment divided by total Common Units outstanding.
[2] Per unit data was calculated using the number of Units issued and outstanding as of June 30, 2026 and 2025.
[3] Not annualized.
[4] The Total Return for the six months ended June 30, 2026 and 2025 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.
[5] 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 13.36% through June 30, 2026. The IRR since inception for the Common Unitholders, after management fees, financing costs and operating expenses is 11.54% through June 30, 2026. 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 actual return may vary significantly upon realization.
[6] Annualized.
