 meet at its regular quarterly meetings with members of senior management to discuss various topics, including market conditions, industry developments and any significant developments or strategic plans for the Fund Advisers, if
any.

To help with the review of performance, the Board and/or its committees periodically received and discussed presentations from member(s) of investment
teams throughout the year, culminating in an annual performance review of the Nuveen funds at the Board’s meeting held on February 25-26, 2025 (the “February Meeting”). The presentations,
discussions and meetings during the year provide a means for the Board Members to evaluate and consider the level, breadth and quality of services provided by the Fund Advisers and any changes to such services over time in light of new or modified
regulatory requirements, changes to market conditions or other factors.

In addition to the materials and discussions that occurred at prior meetings, the
Board, through its independent legal counsel, requested and received extensive materials and information prepared specifically for its review of the Advisory Agreements. During the year, management worked with an ad hoc committee established by the
Board to help enhance and streamline the materials provided in connection with the annual review of the Advisory Agreements. The materials provided at the Meeting and/or prior meetings covered a wide range of matters including, but not limited to, a
description of the nature, extent and quality of services provided by the Fund Advisers; a review of the Sub-Adviser and applicable investment team; an analysis of fund performance with a focus on funds
considered to have met certain challenged performance measurements; an analysis of the fees and expense ratios of the Nuveen funds with a focus on funds considered to have certain expense characteristics; a list of management fee and sub-advisory fee schedules; an analysis of advisory fees compared to fees assessed to other types of clients; a description of portfolio manager compensation; certain profitability and/or financial data; and a
description of indirect benefits received by the Fund Advisers as a result of their relationships with the Nuveen funds. The Board also considered information provided by Broadridge Financial Solutions, Inc. (“Broadridge”), an independent
provider of investment company data, comparing fee and expense levels of each respective Fund to those of a peer universe.
