IMPORTANT NOTICE:

Shareholder Meeting Adjourned until March 2, 2016

Please exercise your right to vote as soon as possible!

Dear Shareholder:

It is urgent for you to vote as soon as possible on a proposal that affects your investment in your Nuveen fund.

The shareholder meeting has been adjourned. In October, we mailed you a Joint Proxy Statement/Prospectus requesting your vote on an important proposal affecting your fund. The meeting to decide on this proposal has adjourned several times. This meeting will be reconvened on March 2, 2016 at 2:00 PM CT, at the offices of Nuveen Investments, 333 West Wacker Drive, Chicago, IL 60606. This letter was sent because you held shares in the fund on the record date and we have not received your vote.

YOUR FUND’S BOARD RECOMMENDS YOU VOTE “FOR” THE PROPOSAL
