 for an economic benefit by the narrowing of the discount or widening of the premium. To the extent MVT’s, MIY’s or MVF’s common shares are trading at a narrower discount (or wider premium) than the Acquiring Fund at the time of its Reorganization, MVT’s, MIY’s or MVF’s common shareholders may be negatively impacted if its Reorganization is consummated. Acquiring Fund common shareholders would only benefit from a premium/discount perspective to the extent the post-Reorganization discount (or premium) of the Acquiring Fund common shares improves. There can be no assurance that, after the Reorganizations, common shares of the Combined Fund will trade at, above or below NAV. Upon consummation of the Reorganizations, the Combined Fund common shares may trade at a price that is less than the current market price of Acquiring Fund common shares. In the Reorganizations, common shareholders of MVT, MIY and MVF will receive Acquiring Fund common shares based on the relative NAVs (not the market values) of the respective Fund’s common shares. The market value of the common shares of the Combined Fund may be less than the market value of the common shares of a Fund prior to the Reorganizations. If the Reorganization is approved by shareholders, effective upon the closing of the Reorganization, the Combined Fund will adopt a discount management program under which the Combined Fund will, beginning in 2026, intend to offer to purchase a minimum of 5% of its outstanding common shares, subject to the Board’s discretion, at a price equal to 98% of NAV per common share via annual tender offer if the Combined Fund’s common shares trade at an average daily discount to NAV of more than 10.00% during a measurement period beginning on January 1st and concluding on September 30th of each calendar year (the “Discount Management 134

Program”). Even if a tender offer is triggered under the Discount Management Program, there is no guarantee that Combined Fund shareholders will be able to sell all of the shares that they desire to sell in any particular tender offer and there can be no assurances as to the effect that the Discount Management Program will have on the market for the Combined Fund’s shares or the discount at which the Combined Fund’s shares may trade relative to its NAV.
