Ladies and Gentlemen:

     We received comments from the Staff of the Securities and Exchange Commission (the “SEC”), pursuant to a phone conversation on January 15, 2009, regarding each Fund’s

preliminary proxy statement on Schedule 14A, which was filed on January 9, 2009. We responded to those comments in a letter dated January 21, 2009. On January 22, 2009, we discussed with the Staff one further comment, which is described below.

     We respectfully submit this response letter on behalf of the Funds. We have, for the Staff’s convenience, repeated below the comment that we received, followed immediately by the firm’s response as Fund counsel. The comment and our response, as summarized below, applies to all of the Funds. The Funds intend to file definitive proxy statements including the following response as soon as practicable.

Comment:

     In accordance with the Instructions to Item 22(a)(3)(iv) of Schedule 14A, disclose that the proposed revisions to the Funds’ advisory agreements would not result in any changes to the Funds’ fees and expenses that would be reflected in a pro forma fee table.

Response:

     In response to the staff’s comment, in the discussion of the proposal to revise the Funds’ advisory agreements, the following statement regarding the effect of the revised agreements on the Funds’ overall expenses will be amended to read as follows (amended language in bold):

The revisions to the Advisory Agreement will not result in
any change in advisory fee rates or the level or quality of
advisory services provided to the Funds, and will not
materially increase the Funds’ overall expense ratios.
Accordingly, the revisions to the Advisory Agreement
would not result in any changes to the information
presented in an annual operating expense table
summarizing each Fund's expenses.

General Comments and Responses Thereto

     It was requested that each Fund provide the following representations in its response to comments:

In connection with this filing, each Fund acknowledges that:

1. The Fund is responsible for the adequacy and accuracy of the disclosure in the filing;

2.	Staff comments or changes to disclosure in response to staff comments in the filing reviewed by the staff do not foreclose the SEC from taking any action with respect to the filing; and
3.	The Fund may not assert staff comments as a defense in any proceeding initiated by the SEC or any person under the federal securities laws of the United States.

     As previously noted, we intend to file definitive copies of the proxy, including the response outlined above, once the staff’s comments are resolved. We appreciate your continued cooperation in preparing these proxy statements.
