foreign tax filings, if applicable.

(d)All Other Fees include amounts for products and services provided by the principal accountant, other than the services reported in paragraphs (a) through (c) above and typically include SOC-1 reviews.

(e)(1) Audit Committee Pre-Approval Policies and Procedures The registrant's Audit Committee is required to pre-approve the engagement of the registrant's independent auditors to provide

audit and non-audit services to the registrant and non-audit services to its investment adviser (excluding any sub-adviser whose role is primarily portfolio management and is sub-contracted or overseen by another investment adviser (the "Adviser") or any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund (a "Control Affiliate") if the engagement relates directly to the operations and financial reporting of the registrant.

The Audit Committee has adopted a Policy for Engagement of Independent Auditors for Audit and Non- Audit Services (the "Policy"). The Policy sets forth the understanding of the Audit Committee regarding the engagement of the registrant's independent accountants to provide (i) audit and permissible audit- related, tax and other services to the registrant ("Fund Services"); (ii) nonaudit services to the registrant's Adviser and any Control Affiliates, that relates directly to the operations and financial reporting of a Fund ("Fund-related Adviser Services"); and (iii) certain other audit and non-audit services to the registrant's Adviser and its Control Affiliates. A service will require specific pre-approval by the Audit Committee if it is to be provided by the Fund's independent auditor; provided, however, that pre- approval of non-audit services to the Fund, the Adviser or Control Affiliates may be waived if certain de minimis requirements set forth in the SEC's rules are met.

Under the Policy, the Audit Committee may delegate pre-approval authority to any pre-designated member or members who are independent board members. The member(s) to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next regular meeting. The Audit Committee's responsibilities with respect to the pre- approval of services performed by the independent auditor may not be delegated to management.

On an annual basis, at a regularly scheduled Audit Committee meeting, the Fund's Treasurer or other Fund officer shall submit to the Audit Committee a schedule of the types of Fund Services and Fund- related Adviser Services that are subject to specific preapproval. This schedule will provide a description of each type of service that is subject to specific pre-approval, along with total projected fees for each service. The pre-approval will generally cover a one-year period. The Audit Committee will review and approve the types of services and the projected fees for the next one-year period and may add to, or subtract from, the list of preapproved services from time to time, based on subsequent determinations. This specific approval acknowledges that the Audit

Committee is in agreement with the specific types of services that the independent auditor will be permitted to perform and the projected fees for each service.

The Fund's Treasurer or other Fund officer shall report to the Audit Committee at each of its regular meetings regarding all Fund Services or Fund-related Adviser Services provided since the last such report was rendered, including a description of the services, by category, with forecasted fees for the annual reporting period, proposed changes requiring specific pre-approval and a description of services provided by the independent auditor, by category, with actual fees during the current reporting period.

(e)(2) None, or 0%, of the Audit-Related Fees, Tax Fees and All Other Fees paid by the Fund or affiliated entities relating directly to the operations and financial reporting of the Registrant disclosed above were approved by the audit committee pursuant to paragraphs (c)(7)(i)(C) of Rule 2-01 of Regulation S-X (which permits audit committee approval after the start of the engagement with respect to services other than audit, review or attest services, if certain conditions are satisfied).

(f)Not applicable.

(g)The aggregate non-audit fees billed by the registrant's accountant for services rendered to the registrant and rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the

adviser that provides ongoing services to the registrant.

(h)The registrant's Audit Committee of the Board of Directors has considered whether the provision of non-audit services that were rendered to the registrant's adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, is compatible with maintaining the principal accountant's independence.

(i)Not applicable.

(j)Not applicable.

Item 12. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

Proxy Voting Policies and Procedures

General. The Funds have delegated to the Investment Manager the responsibility to vote proxies relating to portfolio securities held by the Funds, including Funds managed by subadvisers. In deciding to delegate this responsibility to the Investment Manager, the Board reviewed the policies adopted by the Investment Manager. These included the procedures that the Investment Manager follows when a vote presents a conflict between the interests of the Funds and their shareholders and the Investment Manager and its affiliates.

The Investment Manager's policy is to vote all proxies for Fund securities in a manner considered by the Investment Manager to be in the best economic interests of its clients, including the Funds, without regard to any benefit or detriment to the Investment Manager, its employees or its affiliates. The best economic interests of clients is defined for this purpose as the interest of enhancing or protecting the value of client accounts, considered as a group rather than individually, as the Investment Manager determines in its discretion. The Investment Manager endeavors to vote all proxies of which it becomes aware prior to the vote deadline; provided, however, that in certain circumstances the Investment Manager may refrain from voting securities. For instance, the Investment Manager may refrain from voting foreign securities if it determines that the costs of voting outweigh the expected benefits of voting and typically will not vote securities if voting would impose trading restrictions.

The Board may, in its discretion, vote proxies for the Funds. For instance, the Board may determine to vote on matters that may present a material conflict of interest to the Investment Manager. In addition, the Board may instruct the Investment Manager to vote in accordance with guidelines approved by the Board.

Oversight. The operation of the Investment Manager's proxy voting policy and procedures is overseen by a group of representatives from the Investment Manager and its advisory affiliates. Oversight of the Investment Manager's proxy voting is also provided by a committee within the Investment Manager comprised of portfolio managers and research analysts. The Board reviews on an annual basis, or more frequently if determined appropriate, the Investment Manager's administration of the proxy voting process.

Corporate Governance and Proxy Voting Guidelines (the Guidelines). The Investment Manager has adopted the Guidelines, which set out voting stances on key issues and the broad principles shaping its approach, as well as the types of related voting action the Investment Manager may take. The Guidelines also provide indicative examples of key guidelines used in any given region, which illustrate the standards against which voting decisions are considered. The Investment Manager has developed voting stances that align with the Guidelines and will generally vote in accordance with such voting stances. The Investment Manager may determine to vote differently from the voting stances on particular proposals in the event it determines that doing so is in the clients' best economic interests. The Investment Manager may consider the voting recommendations of analysts, portfolio managers, subadvisers and information obtained from outside resources, including one or more third party research providers. When proposals are not covered by the voting stances or a voting determination must be made on a case-by-casebasis, a portfolio manager or analyst will make the voting determination based on his or her determination of the clients' best economic interests.

Addressing Conflicts of Interest. The Investment Manager seeks to address potential material conflicts of interest by voting in accordance with predetermined voting stances. In addition, if the Investment Manager determines that a material conflict of interest exists, the Investment Manager will invoke one or more of the following conflict management practices: (i) causing the proxies to be voted in accordance with the recommendations of an independent third party (which may be the Investment Manager's proxy voting administrator or research provider); (ii) causing the proxies to be delegated to an independent third party (which may be the Investment Manager's proxy voting administrator or research provider); and (iii) in infrequent cases, forwarding the proxies to an Independent Trustee authorized to vote the proxies for the Funds. A member of a governing body responsible for overseeing proxy voting is prohibited from voting on any proposal for which he or she has a conflict of interest by reason of a direct relationship with the issuer or other party affected by a given proposal. Persons making recommendations are required to disclose any relationship with a party making a proposal or other matter known to the person that would create a potential conflict of interest.

Voting Proxies of Affiliated Underlying Funds. Certain Funds may invest in shares of other Columbia Funds (referred to in this context as "underlying funds") and may own substantial portions of these underlying funds. If such Funds are in a master-feeder structure, the feeder fund will either seek instructions from its shareholders with regard to the voting of proxies with respect to the master fund's shares and vote such proxies in accordance with such instructions or vote the shares held by it in the same proportion as the vote of all other master fund shareholders. With respect to Funds that hold shares of underlying funds other than in a master-feeder structure, the holding Funds will typically vote proxies of the underlying funds in the same proportion as the vote of all other holders of the underlying fund's shares, unless the Board otherwise instructs.

Proxy Voting Agents. The Investment Manager has retained Institutional Shareholder Services Inc., a third- party vendor, as its proxy voting administrator to implement its proxy voting process and to provide recordkeeping and vote disclosure services. Typically, Institutional Shareholder Services Inc. populates

ballots for issuers deemed to present potential material conflicts of interest in accordance with predetermined voting stances, as described above under Addressing Conflicts of Interest. The Investment Manager has retained both Institutional Shareholder Services Inc. and Glass Lewis & Company, LLC to provide proxy research services.

Additional Information. Information regarding how the Columbia Funds (except certain Columbia Funds that do not invest in voting securities) voted proxies relating to portfolio securities during the most recent twelve month period ended June 30 will be available by August 31 of this year free of charge: (i) through the Columbia Funds' website at columbiathreadneedleus.com and/or (ii) on the SEC's website at www.sec.gov.

Mr. Callan joined the Investment Manager in 2007. Mr. Callan began his investment career in 2003 and earned a B.S. from the University of Minnesota and an M.B.A. from the University of Minnesota Carlson School of Management.

Mr. Osborn joined the Investment Manager in 2004. Mr. Osborn began his investment career in 2004 and earned a B.B.A. from the University of Wisconsin-Madison.

Other Accounts Managed by the Portfolio Managers:

AS OF FYE 7/31/25

*RIC refers to a Registered Investment Company; PIV refers to a Pooled Investment Vehicle.

**Number and type of accounts for which the advisory fee paid is based in part or wholly on performance and the aggregate net assets in those accounts.

Potential Conflicts of Interest:

Columbia Management: Like other investment professionals with multiple clients, a Fund's portfolio manager(s)

may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The Investment Manager and the Funds have adopted compliance policies and procedures that attempt to address certain of the potential conflicts that portfolio managers face in this regard. Certain of these conflicts of interest are summarized below.

The management of funds or other accounts with different advisory fee rates and/or fee structures, including accounts, such as the Investment Manager's hedge funds, that pay advisory fees based on account performance (performance fee accounts), may raise potential conflicts of interest for a portfolio manager by creating an incentive to favor accounts that pay higher fees, including performance fee accounts, such that the portfolio manager may have an incentive to allocate attractive investments disproportionately to performance fee accounts.

Similar conflicts of interest also may arise when a portfolio manager has personal investments in other accounts that may create an incentive to favor those accounts. When the Investment Manager determines it necessary or appropriate in order to ensure compliance with restrictions on joint transactions under the 1940 Act, a Fund may not be able to invest in privately-placed securities in which other accounts advised by the Investment Manager using a similar style, including performance fee accounts, are able to invest, even when the Investment Manager believes such securities would otherwise represent attractive investment opportunities. As a general matter and subject to the Investment Manager's Code of Ethics and certain limited exceptions, including for investments in the Investment Manager's hedge funds, the Investment Manager's investment professionals do not have the opportunity to invest in client accounts, other than the Funds.

A portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those Funds and/or accounts. The effects of this potential conflict may be more pronounced where Funds and/or accounts managed by a particular portfolio manager have different investment strategies.

A portfolio manager may be able to select or influence the selection of the broker/dealers that are used to execute securities transactions for the Funds. A portfolio manager's decision as to the selection of broker/dealers could produce disproportionate costs and benefits among the Funds and the other accounts the portfolio manager manages.

A potential conflict of interest may arise when a portfolio manager buys or sells the same securities for a Fund and other accounts. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Investment Manager's trading desk may, to the extent consistent with applicable laws and regulations, aggregate the securities to be sold or bought in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if a portfolio manager favors one account over another in allocating the securities bought or sold. The Investment Manager and its Participating Affiliates may coordinate their trading operations for certain types of securities and transactions pursuant to personnel-sharing agreements or similar intercompany arrangements. However, typically the Investment Manager does not coordinate trading activities with a Participating Affiliate with respect to accounts of that Participating Affiliate unless such Participating Affiliate is also providing trading services for accounts managed by the Investment Manager. Similarly, a Participating Affiliate typically does not coordinate trading activities with the Investment Manager with respect to accounts of the Investment Manager unless the Investment Manager is also providing trading services for accounts managed by such Participating Affiliate. As a result, it is possible that the Investment Manager and its Participating Affiliates may trade in the same instruments at the same time,

in the same or opposite direction or in different sequence, which could negatively impact the prices paid by the Fund on such instruments. Additionally, in circumstances where trading services are being provided on a coordinated basis for the Investment Manager's accounts (including the Funds) and the accounts of one or more Participating Affiliates in accordance with applicable law, it is possible that the allocation opportunities available to the Funds may be decreased, especially for less actively traded securities, or orders may take longer to execute, which may negatively impact Fund performance.

"Cross trades," in which a portfolio manager sells a particular security held by a Fund to another account (potentially saving transaction costs for both accounts), could involve a potential conflict of interest if, for example, a portfolio manager is permitted to sell a security from one account to another account at a higher price than an independent third party would pay. The Investment Manager and the Funds have adopted compliance procedures that provide that any transactions between a Fund and another account managed by the Investment Manager are to be made at a current market price, consistent with applicable laws and regulations.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts managed by its portfolio manager(s). Depending on another account's objectives and other factors, a portfolio manager may give advice to and make decisions for a Fund that may differ from advice given, or the timing or nature of decisions made, with respect to another account. A portfolio manager's investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a portfolio manager may buy or sell a particular security for certain accounts, and not for a Fund, even though it could have been bought or sold for the Fund at the same time. A portfolio manager also may buy a particular security for one or more accounts when one or more other accounts are selling the security (including short sales). There may be circumstances when a portfolio manager's purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts, including the Funds.

To the extent a Fund invests in underlying funds, a portfolio manager will be subject to additional potential conflicts of interest. Because of the structure of funds-of-funds, the potential conflicts of interest for the portfolio managers may be different than the potential conflicts of interest for portfolio managers who manage other Funds. The Investment Manager and its affiliates may receive higher compensation as a result of allocations to underlying funds with higher fees.

AFund's portfolio manager(s) also may have other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could exist in managing the Fund and other accounts. Many of the potential conflicts of interest to which the Investment

Manager's portfolio managers are subject are essentially the same or similar to the potential conflicts of interest related to the investment management activities of the Investment Manager and its affiliates.

In addition, a portfolio manager's responsibilities may include working as a securities analyst. This dual role may give rise to conflicts with respect to making investment decisions for accounts that he/she manages versus communicating his/her analyses to other portfolio managers concerning securities that he/she follows as an analyst.

Structure of Compensation

Columbia Management: Portfolio manager direct compensation is typically comprised of a base salary, and an annual incentive award that is paid either in the form of a cash bonus if the size of the award is under a specified threshold, or, if the size of the award is over a specified threshold, the award is paid in a combination of a cash bonus, an equity incentive award, and deferred compensation. Equity incentive awards are made in the form of Ameriprise Financial restricted stock or, for more senior employees, both Ameriprise Financial restricted stock and stock options. The investment return credited on deferred compensation is based on the performance of specified Columbia Funds, in most cases including the Columbia Funds the portfolio manager manages.

Base salary is typically determined based on market data relevant to the employee's position, as well as other factors including internal equity. Base salaries are reviewed annually, and increases are typically given as promotional increases, internal equity adjustments, or market adjustments.

Under the Columbia Management annual incentive plan for investment professionals, awards are discretionary, and the amount of incentive awards for investment team members is variable based on

(1)an evaluation of the investment performance of the investment team of which the investment professional is a member, reflecting the performance (and client experience) of the funds or accounts the investment professional manages and, if applicable, reflecting the individual's work as an investment research analyst, (2) the results of a peer and/or management review of the individual, taking into account attributes such as team participation, investment process followed, communications, and leadership, and (3) the amount of aggregate funding of the plan determined by senior management of Columbia Threadneedle Investments and Ameriprise Financial, which takes into account Columbia Threadneedle Investments revenues and profitability, as well as Ameriprise Financial profitability, historical plan funding levels and other factors. Columbia Threadneedle Investments revenues and profitability are largely determined by assets under management. In determining the allocation of incentive compensation to investment teams, the amount of assets and related revenues managed by the team is also considered, alongside investment performance. Individual awards are subject to a comprehensive risk adjustment review process to ensure proper reflection in remuneration of adherence to our controls and Code of Conduct.

Investment performance for a fund or other account is measured using a scorecard that compares account performance against benchmarks, custom indexes and/or peer groups. Account performance may also be compared to unaffiliated passively managed ETFs, taking into consideration the management fees of comparable passively managed ETFs, when available and as determined by the Investment Manager. Consideration is given to relative performance over the one-, three- and five-year periods, with the largest weighting on the three-year comparison. For individuals and teams that manage multiple strategies and accounts, relative asset size is a key determinant in calculating the aggregate score, with weighting typically proportionate to actual assets. For investment leaders who have group management responsibilities, another factor in their evaluation is an assessment of the group's overall investment performance. Exceptions to this general approach to bonuses exist for certain teams and individuals.

Equity incentive awards are designed to align participants' interests with those of the shareholders of Ameriprise Financial. Equity incentive awards vest over multiple years, so they help retain employees.

Deferred compensation awards are designed to align participants' interests with the investors in the Columbia Funds and other accounts they manage. The value of the deferral account is based on the performance of Columbia Funds. Employees have the option of selecting from various Columbia Funds for their deferral account, however portfolio managers must (other than by strict exception) allocate a minimum of 25% of their incentive awarded through the deferral program to the Columbia Fund(s) they manage. Deferrals vest over multiple years, so they help retain employees.

For all employees the benefit programs generally are the same and are competitive within the financial services industry. Employees participate in a wide variety of plans, including options in Medical, Dental, Vision, Health Care and Dependent Spending Accounts, Life Insurance, Long Term Disability Insurance, 401(k), and a cash balance pension plan.
