(each, an “Acquired Fund”)

As previously announced in August 2010, the Board of Trustees of each Acquired Fund approved a proposal to merge the Acquired Fund with and into the corresponding acquiring fund listed in the table below (each, an “Acquiring Fund”). Each merger is expected to be a tax-free reorganization for U.S. federal income tax purposes. More information about each Acquiring Fund and the definitive terms of each of the proposed mergers will be included in proxy materials.

Each of the mergers identified in the table below is subject to certain conditions, including final approval by the Board of the Acquired Fund and the Acquiring Fund of the definitive terms of each proposed merger and approval by shareholders of the Acquired Fund. It is currently anticipated that proxy materials regarding the mergers will be distributed to shareholders of the Acquired Funds in early 2011, and that meetings of shareholders to consider the mergers will be held in the first half of 2011.
