Upon consummation of the reorganizations, PDI will acquire all of the assets and assume of all the liabilities of the Fund in exchange for additional common shares of beneficial interest of PDI (“Merger Shares”), and the Fund’s common shareholders will receive Merger Shares (and cash in lieu of fractional Merger Shares, if any), based on the relative net asset value per common share (“NAV”) of the Fund and PDI as of the close of business on December 10, 2021.

In connection with the reorganizations, shares of the Fund are expected to cease trading on the NYSE following the close of regular trading on December 10, 2021. Shares of PDI, including the Merger Shares issued in connection with the reorganizations, will continue to trade on the NYSE upon the opening of regular trading on December 13, 2021. Following the reorganizations, PDI will continue to be managed in accordance with its existing investment objectives and strategies. PDI seeks current income and capital appreciation by utilizing a dynamic asset allocation strategy among multiple sectors of the global credit markets.
