Dear Shareholder:

Unless sufficient shareholders vote by February 22, 2013, the adjournment date for your fund’s Special Shareholders Meeting, your fund will not be able to implement these proposals and may incur additional proxy solicitation costs. The Special Shareholders Meeting will reconvene on February 22, 2013 at 2:30 p.m., Central Time at the offices of Nuveen Investments, 333 West Wacker Drive, Chicago, IL.

 

YOUR FUND’S BOARD RECOMMENDS YOU VOTE “FOR” EACH OF THE PROPOSALS.

Please vote now to help your fund avoid further adjournments.

 

PROPOSALS HAVE THE SUPPORT OF AN INDEPENDENT,

NATIONALLY-RECOGNIZED PROXY ADVISORY FIRM.

Sophisticated institutional investors often look to independent proxy advisory firms for guidance on how to vote their shares. Your fund’s proposals were reviewed and received the support of ISS Governance Services Inc. (ISS), widely recognized as one of the leading independent proxy advisory firms in the nation. Hundreds of major institutional investment firms, mutual funds, and other fiduciaries throughout the country rely upon ISS’ recommendations. ISS recommends that its clients vote “FOR” each of the proposals contained in the proxy.

 

SHAREHOLDERS ARE URGED TO VOTE NOW ON THESE IMPORTANT MATTERS REGARDING THEIR FUND

It’s extremely important that you participate in the management of your investment by voting. Please take a few moments to review the information in the Joint Proxy Statement/Prospectus previously provided to you, and cast your vote now. You may obtain a copy of the Joint Proxy Statement/Prospectus at

The Board has determined that the proposed Reorganizations would be in the best interests of each Fund. The Acquiring Fund and the Acquired Funds have substantially similar investment objectives and policies, substantially similar portfolio compositions, and are managed by the same portfolio manager. The proposed Reorganizations are intended to result in lower operating expenses (excluding costs of leverage) as a result of the larger size of the combined fund and to enhance the secondary trading market for common shares of the Funds.
