[2] Total return based on net asset value is based upon the change in net asset value per share between the opening and ending net asset values per share in the period. The total returns are not annualized.
[3] Per share data based on weighted average shares outstanding.
[4] Financial Highlights for the periods of less than one year are annualized and the ratios of operating expenses to average net assets and net investment loss to average net assets are adjusted accordingly. Non-recurring expenses are not annualized. For the nine months ended September 30, 2025 and 2024, the Company did not exclude any nonrecurring expenses. Because the ratios are calculated for the Company’s common stock taken as a whole, an individual investor’s ratios may vary from these ratios.
