[1] The Adviser has contractually agreed, through March 31, 2027, to reduce its advisory fee by 0.18%. This fee waiver may only be terminated by the Fund’s Board of Trustees (and not by the Adviser) prior to such date.
[2] The Fund is classified for federal income tax purposes as a taxable regular corporation or so-called Subchapter ‘‘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 and the distributions received by the Fund on equity securities of master limited partnerships considered to be a return of capital and for any net operating gains. 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.
[3] The Fund’s management fees consist of a fee of 0.11% paid to the Fund’s investment adviser and a fee of 0.35% paid to the Fund’s sub-adviser.
