investment in the market, incurring the risk that the value of the replacement security is greater than the value of the collateral. The Fund is also subject to all investment risks associated with the reinvestment of any cash collateral received, including, but not limited to, interest rate, credit and liquidity risk associated with such investments.
As of April 30, 2022, the Fund had securities on loan, which were classified as equity securities in the Investment Portfolio. The value of the related collateral exceeded the value of the securities loaned at period end. As of period end, the remaining contractual maturity of the collateral agreements was overnight and continuous.
Taxes. The Fund’s policy is to comply with the requirements of the Internal Revenue Code, as amended, which are applicable to regulated investment companies, and to distribute all of its taxable income to its shareholders.
Additionally, the Fund may be subject to taxes imposed by the governments of countries in which it invests and are generally based on income and/or capital gains earned or repatriated. Estimated tax liabilities on certain foreign securities are recorded on an accrual basis and are reflected as components of interest income or net change in unrealized gain/loss on investments. Tax liabilities realized as a result of security sales are reflected as a component of net realized gain/loss on investments.
At April 30, 2022, the aggregate cost of investments for federal income tax purposes was $284,177,012. The net unrealized appreciation for all investments based on tax cost was $8,152,823. This consisted of aggregate gross unrealized appreciation for all investments for which there was an excess of value over tax cost of $32,135,833 and aggregate gross unrealized depreciation for all investments for which there was an excess of tax cost over value of $23,983,010.
The Fund has reviewed the tax positions for the open tax years as of October 31, 2021 and has determined that no provision for income tax and/or uncertain tax positions is required in the Fund’s financial statements. The Fund’s federal tax returns for the prior three fiscal years remain open subject to examination by the Internal Revenue Service.
Distribution of Income and Gains. Distributions from net investment income of the Fund, if any, are declared and distributed to shareholders annually. Net realized gains from investment transactions, in excess of available capital loss carryforwards, would be taxable to the Fund if not distributed, and, therefore, will be distributed to shareholders at least annually. The Fund may also make additional distributions for tax purposes if necessary.
The timing and characterization of certain income and capital gain distributions are determined annually in accordance with federal tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences primarily
