U S Bancorp : Asset Management, Inc. : Announces Distribution for American Municipal Income Portfolio Inc.

U.S. Bancorp Asset Management, Inc. (NYSE:USB) today announced a distribution for American Municipal Income Portfolio Inc. (NYSE: XAA) (the “Fund”).

As previously announced, shareholders of the Fund approved a proposal to merge the Fund into Nuveen Investment Quality Municipal Fund, Inc. (NYSE: NQM) (the “Acquiring Fund”), a closed-end fund managed by Nuveen Fund Advisors, LLC and sub-advised by Nuveen Asset Management, LLC, both current sub-advisors of the fund. The merger is expected to become effective on October 6, 2014.

Regulations require that acquired funds in any reorganization fully distribute any accumulated undistributed net investment income prior to effecting the reorganization. Accordingly, the Fund is declaring a distribution which will comply with this regulation, payable October 22, 2014 to shareholders of record on October 3, 2014.

The following dates apply to the distribution declaration for the Fund:

The distribution is payable in cash or, pursuant to the Acquiring Fund’s dividend reinvestment plan, reinvested in additional shares of the Acquiring Fund’s common stock. Under the Acquiring Fund’s plan, the number of common shares received will be determined as follows: (1) If the common shares are trading at or above net asset value at the time of valuation, the Acquiring Fund will issue new common shares at a price equal to the greater of (i) net asset value per common share on that date or (ii) 95% of the market price on that date. (2) If common shares are trading below net asset value at the time of valuation, the plan agent will receive the dividend or distribution in cash and will purchase common shares in the open market, on the New York Stock Exchange or elsewhere, for the participants’ accounts. It is possible that the market price for the common shares may increase before the plan agent has completed its purchases. Therefore, the average purchase price per share paid by the plan agent may exceed the market price at the time of valuation, resulting in the purchase of fewer common shares than if the dividend or distribution had been paid in common shares issued by the Acquiring Fund. The plan agent will use all dividends and distributions received in cash to purchase common shares in the open market within 30 days of the valuation date. Interest will not be paid on any uninvested cash payments. The plan provides that if common shares start trading at or above net asset value before the plan agent has completed its purchases, the plan agent may cease purchasing common shares in the open market, and may invest the uninvested portion in new common shares at a price equal to the greater of (i) net asset value per common share determined on the last business day immediately prior to the purchase date or (ii) 95% of the market price on that date.

Minneapolis-based U.S. Bancorp Asset Management, Inc. serves as investment advisor to the Fund.
