1 The Fund is classified for U.S. federal income tax purposes as a taxable regular corporation or so-called Subchapter “C” corporation (a “C Corporation”). As a C Corporation, the Fund accrues deferred tax liability for its future tax liability associated with the capital appreciation of its investments. The Fund’s accrued deferred tax liability, if any, is reflected each day in the Fund’s net asset value per share. The deferred income tax expense/(benefit) represents an estimate of the Fund’s potential tax expense/(benefit) if it were to recognize the unrealized gains/(losses) in the portfolio. An estimate of deferred income tax expense/(benefit) is dependent upon the Fund’s net investment income/(loss) and realized and unrealized gains/(losses) on investments and such expenses may vary greatly from year to year and from day to day depending on the nature of the Fund’s investments, the performance of those investments and general market conditions. Therefore, any estimate of deferred income tax expense/(benefit) cannot be reliably predicted from year to year. The total net tax expense for the year ended October 31, 2025 was $4,599,174.

Portfolio Turnover [Text Block]

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes to the Fund. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 3% of the average value of its portfolio.
