The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. Each Fund pays all of its other costs and expenses of its operations, including compensation of its Board Members (other than those affiliated with the Adviser), custodian, transfer agency and dividend disbursing expenses, legal fees, expenses of independent auditors, expenses of repurchasing shares, expenses of issuing any preferred shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies, listing fees and taxes, if any.

Each Fund also pays a complex-level fee to Nuveen Fund Advisors, which is payable monthly and is in addition to the fund-level fee. The complex-level fee is based on the aggregate daily amount of eligible assets for all Nuveen-branded closed- and open-end registered investment companies organized in the United States, as stated in the table below. As of August 31, 2025, the complex-level fee rate for each Fund was 0.1568%.

The annual complex-level fee for each Fund, payable monthly, is calculated by multiplying the current complex-wide fee rate, determined according to the following schedule, by a Fund’s daily managed assets:
