If you have not already done so, please fill out and return the enclosed proxy card in a timely fashion. Thank you for your support of the Nuveen family of Closed-End Exchange-Traded portfolios. Q. WHY AM I RECEIVING THIS PROXY STATEMENT? A. Closed-end investment companies listed on the New York Stock Exchange such as your Fund are required to hold annual meetings to approve the election of Trustees. In addition, such companies are required to obtain shareholder approval for certain changes to their organizational documents and changes to their investment policies. Your Fund is seeking shareholder approval on the following items: - An amendment to the Declaration of Trust. - To elect seven (7) trustees to serve for each Fund until the next annual meeting. Please refer to the proxy statement for a detailed explanation of the proposed items. Q. HOW WILL THE PROPOSAL TO AMEND THE DECLARATION OF TRUST AFFECT ME AS A FUND SHAREHOLDER? A. The investment manager for your Fund is seeking to maintain competitive dividend rates. If the amendments to the Declarations of Trust are approved, the Funds' investment manager will have greater ability to invest in higher yielding, longer-term investment grade municipal obligations. The amendments will accomplish this by eliminating the 2017 termination date for each Fund and permit it to operate indefinitely. Q. HAVE SHAREHOLDERS PREVIOUSLY CONSIDERED THE PROPOSAL TO AMEND THE DECLARATION OF TRUST? A. Yes, shareholders considered this proposal at the last annual meeting. However, the proposal failed to receive enough votes to pass. While the vast majority of the shareholders that voted on the proposal voted in favor of the proposal, the solicitation period for the proposal was prematurely terminated as a result of a vote counting error. As a result, the proposal needs to be reconsidered this year. Q. HOW DO THE TRUSTEES OF MY FUND SUGGEST THAT I VOTE? A. After careful consideration, the trustees of your Fund unanimously recommend that you vote "FOR" each of the items proposed. Q. WILL MY VOTE MAKE A DIFFERENCE? A. Your vote is needed to ensure that the proposals can be acted upon. Additionally, your immediate response to these items will help save on the costs of any further solicitations for a shareholder vote. We encourage all shareholders to participate in the governance of their Fund. Q. WHO DO I CALL IF I HAVE QUESTIONS? A. If you need any assistance, or have any questions regarding the proposals or how to vote your shares, please call Nuveen at (800) 257-8787 weekdays from 8:00 a.m. to 6:00 p.m. Central time or your financial advisor.
