[1] The per unit data was derived by using the weighted average units outstanding during the nine months ended September 30, 2025 and 2024, which were 47,777,985 and 47,777,985, respectively.

[2] For financial statement reporting purposes under GAAP, as of September 30, 2025 and 2024, the Company recorded a liability in the amount of $363,000 and $352,000, respectively, for the estimated future amount of Class C distribution fees, Class I dealer manager fees, Class W dealer manager fees and Class W services fees payable. This liability is reflected in this table, which is consistent with the financial statements. While the Company follows GAAP for financial reporting purposes, it has determined that deducting the accrual for the estimated future amount of Class C distribution fees, Class I dealer manager fees, Class W dealer manager fees and Class W services fees may not be the appropriate approach for determining the net asset value used on the quarterly investor statements and for other purposes. The Company believes that not making such deduction for purposes of net asset value determination is consistent with the industry standard and is more appropriate since the Company intends for the net asset value to reflect the estimated value on the date that the Company determines its net asset value.

[3] Total return does not assume the reinvestment of distributions paid and is not annualized.

[4] The Company’s net investment income and expense ratios have been annualized assuming consistent results over a full fiscal year, however, this may not be indicative of actual results over a full fiscal year.
