Investment Policy Revision

Effective August 5, 2016, a number of Nuveen AMT-Free and non-AMT municipal closed-end funds have approved changes to their investment policies altering the limits on exposure to securities subject to the federal alternative minimum tax applicable to individuals (AMT).

AMT FREE MUNICIPAL FUNDS

The two AMT-Free funds listed below adopted a new investment policy to require the funds to invest 100% of its managed assets in securities the income from which is exempt from AMT at the time of purchase. While the funds were previously being managed as such, the new AMT policy will be in addition to the current policy which requires that only 80% of the funds’ assets be invested in securities exempt from the AMT. The 80% policy was adopted to meet the “Names Rule” under the Investment Company Act of 1940 and is subject to change by the board upon 60 days’ notice to shareholders. The new 100% AMT policy is subject to change by the fund’s board without shareholder notice. The new AMT policy is consistent with Nuveen’s other AMT-Free funds. The new policy was adopted for the following funds:

NRK		Nuveen New York AMT-Free Municipal Income Fund
NKX		Nuveen California AMT-Free Municipal Income Fund

MUNICIPAL FUNDS THAT ARE NOT AMT-FREE

All of the Nuveen municipal closed-end funds listed below have adopted an investment policy to limit the amount securities subject to AMT to no more than 20% of a fund’s managed assets. As set forth below the vast majority of these funds previously did not have a limit on AMT securities while six funds had a 30% limit on AMT securities. The new AMT investment policy will replace each fund’s old investment policy. Together with a number of other Nuveen funds, these changes will create a uniform 20% limit on AMT securities across Nuveen’s municipal complex. The following is a list of the funds adopting the new 20% limit and each fund’s previous investment policy with respect to AMT securities.
