Unless sufficient shareholders vote by April 4, 2014, the adjournment date for your fund’s Annual Shareholders Meeting, your fund will not be able to implement these proposals and may incur additional proxy solicitation costs. The Annual Shareholders Meeting will reconvene on April 4, 2014 at 2:00 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,

Sophisticated institutional investors often look to independent proxy advisory firms for guidance on how to vote their shares. Your fund’s proposals were reviewed by and received the support of Institutional Shareholder Services Inc.

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.
