NKL Nuveen Insured California Dividend Advantage Municipal Fund Common Shares of Beneifical Interest

Nuveen Investments, a leading global provider of investment services to institutions as well as individual investors, today announced that the mergers of four California closed-end funds into a single, larger state fund were completed after the close of business on May 4, 2012. As part of the changes approved earlier this year by fund shareholders, each fund also will no longer focus its investment on insured municipal securities, but will continue to invest at least 80 percent of its assets in investment grade quality municipal securities.

The closed-end funds have been merged as follows:

Nuveen Insured California Premium Income Municipal Fund, Inc. (NPC)

Nuveen Insured California Premium Income Municipal Fund 2, Inc. (NCL)

Nuveen Insured California Dividend Advantage Municipal Fund (NKL)

Merged into

Nuveen Insured California Tax-Free Advantage Municipal Fund (NKX)

Concurrently, the Nuveen Insured California Tax-Free Advantage Municipal Fund changed its name to Nuveen California AMT-Free Municipal Income Fund.

In the merger, NKX acquired substantially all of the assets and liabilities of the California funds with which it was merged in a tax-free transaction in exchange for an equal aggregate value of newly-issued common shares. The exchanges took place based upon the funds’ closing net asset values on May 4, 2012, with California fund shareholders receiving shares of equivalent total net asset value. The exchange ratio at which common shares of each California fund were exchanged for common shares of the NXK is listed below:
