PIONEER FUNDS

APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES

PROVIDED BY THE INDEPENDENT AUDITOR

SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Amundi Asset Management US, Inc., the audit committee and the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund's independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7),sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approvalis required pursuant to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-auditservices that may be provided consistently with Rule 210.2-01may be approved by the Audit Committee itself and any pre-approvalthat may be waived in accordance with Rule 210.2-01(c)(7)(i)(C)is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.

ITEM 9. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR OPEN-ENDMANAGEMENT INVESTMENT COMPANIES. (Unaudited)

Introduction

This Proxy Voting policy and the procedures set forth below are designed to complement Amundi US' investment policies and procedures regarding its general responsibility to monitor the performance and/or corporate events of companies that are issuers of securities held in accounts managed by Amundi US. This policy sets forth Amundi US' position on a number of issues for which proxies may be solicited but it does not include all potential voting scenarios or proxy events. Furthermore, because of the special issues associated with proxy solicitations by closed-endFunds, Amundi US will vote shares of closed-endFunds on a case- by-casebasis.

Purpose

The purpose of this policy is to ensure that proxies for United States ("US") and non-UScompanies that are received in a timely manner will be voted in accordance with the principles stated above. Unless the Proxy Voting Oversight Group (as described below) specifically determines otherwise, all shares in a company held by Amundi US-managedaccounts for which Amundi US has proxy-voting authority will be voted alike, unless a client has given specific voting instructions on an issue.

Scope

Amundi US does not delegate the authority to vote proxies relating to securities held by its clients to any of its affiliates. Any questions about this policy should be directed to Amundi US' Chief of Staff U.S. Investments (the "Proxy Coordinator").

Oversight and Governance

Administration

The development, implementation, and management, to this Policy is the responsibility of the Policy Contact, in conjunction with the Policy Owner and relevant stakeholders.

Policy Exceptions

Temporary deviation from the requirements of this Policy is deemed an Exception. Exceptions are expected to be infrequent but may be justified to address and/or resolve specific internal business needs. Exceptions are to be raised to the Policy Owner for approval.

Policy Requirements

Roles and Responsibility

The below table outlines the roles and responsibilities applicable to this policy:

Individual Role Responsibility

Policy Owner and Contact Reviews and updates of this Policy as necessary.

Pioneer Funds Board of Trustees and US Compliance Committee Provides final approval of material updates to this Policy, as necessary.

Policy

Each of the Pioneer Funds and certain other clients of Amundi Asset Management US, Inc. ("Amundi US") have delegated responsibility to vote proxies related to portfolio holdings to Amundi US. Amundi US is a fiduciary that owes each of its clients the duties of care and loyalty with respect to all services undertaken on the client's behalf, including voting proxies for securities held by the client. When Amundi US has been delegated proxy-voting authority for a client, the duty of care requires Amundi US to monitor corporate events and to vote the proxies. To satisfy its duty of loyalty, Amundi US must place the client's interests ahead of its own and must cast proxy votes in a manner consistent with the best interest of the client. It is Amundi US' policy to vote proxies presented to Amundi US in a timely manner in accordance with these principles.

Amundi US' fundamental concern in voting proxies is the economic effect of the proposal on the value of portfolio holdings, considering both the short- and long-term impact. In many instances, Amundi US believes that supporting the company's strategy and voting "for" management's proposals builds portfolio value. In other cases, however, proposals set forth by management may have a negative effect on that value, while some shareholder proposals may hold the best prospects for enhancing it. Amundi US monitors developments in the proxy voting arena and will revise this policy as needed.

Amundi US believes that environmental, social and governance (ESG) factors can affect companies' long-term prospects for success and the sustainability of their business models. Since ESG factors that may affect corporate performance and economic value are considered by our investment professionals as part of the investment management process, Amundi US also considers these factors when reviewing proxy proposals. This approach is consistent with the stated investment objectives and policies of funds and investment strategies.

It should be noted that the proxy voting guidelines below are guidelines, not rules, and Amundi US reserves the right in all cases to vote contrary to guidelines where doing so is determined to represent the best economic interests of our clients. Further, the Pioneer Funds or other clients of Amundi US may direct Amundi US to vote contrary to guidelines.

Amundi US' clients may request copies of their proxy voting records and of Amundi US' proxy voting policies and procedures by either sending a written request to Amundi US' Proxy Coordinator, or clients may review Amundi US' proxy voting policies and procedures on-lineat amundi.com/usinvestors. Amundi US may describe to clients its proxy voting policies and procedures by delivering a copy of Amundi US' Form ADV (Part II), by separate notice to the client or by other means.

Procedures

Proxy Voting Service

Amundi US has engaged an independent proxy voting service to assist in the voting of proxies. The proxy voting service works with custodians to ensure that all proxy materials are received by the custodians and are processed in a timely fashion. The proxy voting service votes all proxies in accordance with the proxy voting guidelines established by Amundi US and set forth herein, to the extent applicable. The proxy voting service will refer proxy questions to the Proxy Coordinator (described below) for instructions under circumstances where: (1) the application of the proxy voting guidelines is unclear; (2) a particular proxy question is not covered by the guidelines; or (3) the guidelines call for specific instructions on a case-by-casebasis. The proxy voting service is also requested to call to the Proxy Coordinator's attention specific proxy questions that, while governed by a guideline, appear to involve unusual or controversial issues. Amundi US reserves the right to attend a meeting in person and may do so when it determines that the company or the matters to be voted on at the meeting are strategically important to its clients.

To supplement its own research and analysis in determining how to vote on a particular proxy proposal, Amundi US may utilize research, analysis or recommendations provided by the proxy voting service on a case-by-casebasis. Amundi US does not, as a policy, follow the assessments or recommendations provided by the proxy voting service without its own analysis and determination.

Proxy Coordinator

The Proxy Coordinator coordinates the voting, procedures and reporting of proxies on behalf of Amundi US' clients. The Proxy Coordinator will deal directly with the proxy voting service and, in the case of proxy questions referred by the proxy voting service, will solicit voting recommendations and instructions from the Portfolio Management Group, or, to the extent applicable, investment sub-advisers.The Proxy Coordinator is responsible for ensuring that these questions and referrals are responded to in a timely fashion and for transmitting appropriate voting instructions to the proxy voting service. The Proxy Coordinator is responsible for verifying with the General Counsel or his or her designee whether Amundi US' voting power is subject to any limitations or guidelines issued by the client (or in the case of an employee benefit plan, the plan's trustee or other fiduciaries).

Referral Items

The proxy voting service will refer proxy questions to the Proxy Coordinator or his or her designee that are described by Amundi US' proxy voting guidelines as to be voted on a case- by-casebasis, that are not covered by Amundi US' guidelines or where Amundi US' guidelines may be unclear with respect to the matter to be voted on. Under such circumstances, the Proxy Coordinator will seek a written voting recommendation from the Chief Investment Officer, U.S or his or her designated equity portfolio-management representative. Any such recommendation will include: (i) the manner in which the proxies should be voted; (ii) the rationale underlying any such decision; and (iii) the disclosure of any contacts or communications made between Amundi US and any outside parties concerning the proxy proposal prior to the time that the voting instructions are provided.

Securities Lending

In accordance with industry standards, proxies are not available to be voted when the shares are out on loan through either Amundi US' lending program or a client's managed security lending program. However, Amundi US will reserve the right to recall lent securities so that they may be voted according to Amundi US' instructions. If a portfolio manager would like to vote a block of previously lent shares, the Proxy Coordinator will work with the portfolio manager and Investment Operations to recall the security, to the extent possible, to facilitate the vote on the entire block of shares. Certain clients participate in securities lending programs. Although such programs allow for the recall of securities for any reason, Amundi US may determine not to vote securities on loan and it may not always be possible for securities on loan to be recalled in time to be voted.

Share-Blocking

"Share-blocking" is a market practice whereby shares are sent to a custodian (which may be different than the account custodian) for record keeping and voting at the general meeting. The shares are unavailable for sale or delivery until the end of the blocking period (typically the day after general meeting date).

Amundi US will vote in those countries with "share-blocking." In the event a manager would like to sell a security with "share-blocking", the Proxy Coordinator will work with the Portfolio Manager and Investment Operations Department to recall the shares (as allowable within the market time-frame and practices) and/or communicate with executing brokerage firm. A list of countries with "share-blocking" is available from the Investment Operations Department upon request.

Proxy Voting Oversight Group

The members of the Proxy Voting Oversight Group include Amundi US' Chief Investment Officer, U.S. or his or her designated equity portfolio management representative, the Chief of Staff, U.S., and the Chief Compliance Officer of the Adviser and Funds. Other members of Amundi US will be invited to attend meetings and otherwise participate as necessary. The Chief of Staff, U.S. will chair the Proxy Voting Oversight Group.

The Proxy Voting Oversight Group is responsible for developing, evaluating, and changing (when necessary) Amundi US' proxy voting policies and procedures. The Group meets at least annually to evaluate and review this policy and the services of its third-party proxy voting service. In addition, the Proxy Voting Oversight Group will meet as necessary to vote on referral items and address other business as necessary.

Amendments

Amundi US may not amend this policy without the prior approval of the Proxy Voting Oversight Group. Amendments to this policy with respect to votes to be cast on behalf of any of the Pioneer Funds also shall be presented to the Board of Trustees of the Pioneer Funds for its review and advance approval.

Form N-PX

The Proxy Coordinator and the Director of Regulatory Reporting are responsible for ensuring that Form NP-Xdocuments receive the proper review by a member of the Proxy Voting Oversight Group prior to a Fund officer signing the forms.

The Proxy Coordinator will provide the Compliance department with a copy of each Form N-PXfiling prepared by the proxy voting service.

Compliance files N-PX.The Compliance department will ensure that a corresponding Form N-PX exists for each Amundi US registered investment company.

Following this review, each Form N-PXis formatted for public dissemination via the EDGAR system.

Prior to submission, each Form N-PXis to be presented to the Fund officer for a final review and signature.

Copies of the Form N-PXfilings and their submission receipts are maintained according to Amundi US record keeping policies.

Proxy Voting Guidelines

Administrative

While administrative items appear infrequently in U.S. issuer proxies, they are quite common in non-U.S.proxies.

We will generally support these and similar management proposals:

•

Corporate name change.

•

A change of corporate headquarters.

•

Stock exchange listing.

•

Establishment of time and place of annual meeting.

•

Adjournment or postponement of annual meeting.

•

Acceptance/approval of financial statements.

•

Approval of dividend payments, dividend reinvestment plans and other dividend-related proposals.

•

Approval of minutes and other formalities.

•

Authorization of the transferring of reserves and allocation of income.

•

Amendments to authorized signatories.

•

Approval of accounting method changes or change in fiscal year-end.

•

Acceptance of labor agreements.

•

Appointment of internal auditors.

Amundi US will vote on a case-by-casebasis on other routine administrative items; however, Amundi US will oppose any routine proposal if insufficient information is presented in advance to allow Amundi US to judge the merit of the proposal. Amundi US has also instructed its proxy voting service to inform Amundi US of its analysis of any administrative items that may be inconsistent, in its view, with Amundi US' goal of supporting the value of its clients' portfolio holdings so that Amundi US may consider and vote on those items on a case-by-casebasis in its discretion.

Auditors

We normally vote for proposals to:

•

Ratify the auditors. We will consider a vote against if we are concerned about the auditors' independence or their past work for the company. Specifically, we will oppose the ratification of auditors and withhold votes for audit committee members if non-auditfees paid by the company to the auditing firm exceed the sum of audit fees plus audit-related fees plus permissible tax fees according to the disclosure categories proposed by the Securities and Exchange Commission.

•

Restore shareholder rights to ratify the auditors.

We will normally oppose proposals that require companies to:

•

Seek bids from other auditors.

•

Rotate auditing firms, except where the rotation is statutorily required or where rotation would demonstrably strengthen financial disclosure.

•

Indemnify auditors.

•

Prohibit auditors from engaging in non-auditservices for the company.

Board of Directors

On issues related to the board of directors, Amundi US normally supports management. We will, however, consider a vote against management in instances where corporate performance has been poor or where the board appears to lack independence. We also believe that a well balanced board with diverse perspectives is conducive to sound corporate governance. In our view, diversity of expertise, skill, gender, ethnicity, and race may contribute to the overall quality of decision making and risk management.

General Board Issues

Amundi US will vote for:

•

Audit, compensation and nominating committees composed of independent directors exclusively.

•

Indemnification for directors for actions taken in good faith in accordance with the business judgment rule. We will vote against proposals for broader indemnification.

•

Changes in board size that appear to have a legitimate business purpose and are not primarily for anti-takeover reasons.

•

Election of an honorary director.

We will vote against:

•

Minimum stock ownership by directors.

•

Term limits for directors. Companies benefit from experienced directors, and shareholder control is better achieved through annual votes.

•

Requirements for union or special interest representation on the board.

•

Requirements to provide two candidates for each board seat.

We will vote on a case-bycase basis on these issues:

•

Separate chairman and CEO positions. We will consider voting with shareholders on these issues in cases of poor corporate performance.

Elections of Directors

In uncontested elections of directors we will vote against:

•

Individual directors with absenteeism above 25% without valid reason. We support proposals that require disclosure of director attendance.

•

Insider directors and affiliated outsiders who sit on the audit, compensation, stock option or nominating committees. For the purposes of our policy, we use the definition of affiliated directors provided by our proxy voting service.

We will also vote against:

•

Directors who have failed to act on a takeover offer where the majority of shareholders have tendered their shares.

•

Directors who appear to lack independence or are associated with poor corporate or governance performance.

We will vote on a case-bycase basis on these issues:

•

Re-electionof directors who have implemented or renewed a dead hand or modified dead-hand poison pill (a "dead-hand poison pill" is a shareholder rights plan that may be altered only by incumbent or "dead" directors. These plans prevent a potential acquirer from disabling a poison pill by obtaining control of the board through a proxy vote).

•

Contested election of directors.

•

Election of a greater number of independent directors (in order to move closer to a majority of independent directors) in cases of poor performance.

•

Mandatory retirement policies.

•

Directors who have ignored a shareholder proposal that has been approved by shareholders for two consecutive years.

We will vote for:

•

Precatory and binding resolutions requesting that the board changes the company's bylaws to stipulate that directors need to be elected with affirmative majority of votes cast, provided that the resolutions allow for plurality voting in cases of contested elections.

Takeover-Related Measures

Amundi US is generally opposed to proposals that may discourage takeover attempts. We believe that the potential for a takeover helps ensure that corporate performance remains high.

Amundi US will vote for:

•

Cumulative voting.

•

Increasing the ability for shareholders to call special meetings.

•

Increasing the ability for shareholders to act by written consent.

•

Restrictions on the ability to make greenmail payments.

•

Submitting rights plans to shareholder vote.

•

Rescinding shareholder rights plans ("poison pills").

•

Opting out of the following state takeover statutes:

•

Control share acquisition statutes, which deny large holders voting rights on holdings over a specified threshold.

•

Control share cash-outprovisions, which require large holders to acquire shares from other holders.

•

Freeze-outprovisions, which impose a waiting period on large holders before they can attempt to gain control.

•

Stakeholder laws, which permit directors to consider interests of non-shareholderconstituencies.

•

Disgorgement provisions, which require acquirers to disgorge profits on purchases made before gaining control.

•

Fair price provisions.

•

Authorization of shareholder rights plans.

•

Labor protection provisions.

•

Mandatory classified boards.

We will vote on a case-by-casebasis on the following issues:

•

Fair price provisions. We will vote against provisions requiring supermajority votes to approve takeovers. We will also consider voting against proposals that require a supermajority vote to repeal or amend the provision. Finally, we will consider the mechanism used to determine the fair price; we are generally opposed to complicated formulas or requirements to pay a premium.

•

Opting out of state takeover statutes regarding fair price provisions. We will use the criteria used for fair price provisions in general to determine our vote on this issue.

•

Proposals that allow shareholders to nominate directors.

We will vote against:

•

Classified boards, except in the case of closed-endfunds, where we shall vote on a case-by-casebasis.

•

Limiting shareholder ability to remove or appoint directors. We will support proposals to restore shareholder authority in this area. We will review on case-by-casebasis proposals that authorize the board to make interim appointments.

•

Classes of shares with unequal voting rights.

•

Supermajority vote requirements.

•

Severance packages ("golden" and "tin" parachutes). We will support proposals to put these packages to shareholder vote.

•

Reimbursement of dissident proxy solicitation expenses. While we ordinarily support measures that encourage takeover bids, we believe that management should have full control over corporate funds.

•

Extension of advance notice requirements for shareholder proposals.

•

Granting board authority normally retained by shareholders, particularly the right to amend the corporate charter.

•

Shareholder rights plans ("poison pills"). These plans generally allow shareholders to buy additional shares at a below-market price in the event of a change in control and may deter some bids.

Capital Structure

Managements need considerable flexibility in determining the company's financial structure, and Amundi US normally supports managements' proposals in this area. We will, however, reject proposals that impose high barriers to potential takeovers.

Amundi US will vote for:

•

Changes in par value.

•

Reverse splits, if accompanied by a reduction in number of shares.

•

Shares repurchase programs, if all shareholders may participate on equal terms.

•

Bond issuance.

•

Increases in "ordinary" preferred stock.

•

Proposals to have blank-check common stock placements (other than shares issued in the normal course of business) submitted for shareholder approval.

•

Cancellation of company treasury shares.

We will vote on a case-by-casebasis on the following issues:

•

Reverse splits not accompanied by a reduction in number of shares, considering the risk of delisting.

•

Increase in authorized common stock. We will make a determination considering, among other factors:

•

Number of shares currently available for issuance;

•

Size of requested increase (we would normally approve increases of up to 100% of current authorization);

•

Proposed use of the proceeds from the issuance of additional shares; and

•

Potential consequences of a failure to increase the number of shares outstanding (e.g., delisting or bankruptcy).

•

Blank-check preferred. We will normally oppose issuance of a new class of blank-check preferred, but may approve an increase in a class already outstanding if the company has demonstrated that it uses this flexibility appropriately.

•

Proposals to submit private placements to shareholder vote.

•

Other financing plans.

We will vote against preemptive rights that we believe limit a company's financing flexibility.

Compensation

Amundi US supports compensation plans that link pay to shareholder returns and believes that management has the best understanding of the level of compensation needed to attract and retain qualified people. At the same time, stock-related compensation plans have a significant economic impact and a direct effect on the balance sheet. Therefore, while we do not want to micromanage a company's compensation programs, we place limits on the potential dilution these plans may impose.

Amundi US will vote for:

•

401(k) benefit plans.

•

Employee stock ownership plans (ESOPs), as long as shares allocated to ESOPs are less than 5% of outstanding shares. Larger blocks of stock in ESOPs can serve as a takeover defense. We will support proposals to submit ESOPs to shareholder vote.

•

Various issues related to the Omnibus Budget and Reconciliation Act of 1993 (OBRA), including:

•

Amendments to performance plans to conform with OBRA;

•

Caps on annual grants or amendments of administrative features;

•

Adding performance goals; and

•

Cash or cash-and-stockbonus plans.

•

Establish a process to link pay, including stock-option grants, to performance, leaving specifics of implementation to the company.

•

Require that option repricing be submitted to shareholders.

•

Require the expensing of stock-option awards.

•

Require reporting of executive retirement benefits (deferred compensation, split dollar life insurance, SERPs, and pension benefits).

•

Employee stock purchase plans where the purchase price is equal to at least 85% of the market price, where the offering period is no greater than 27 months and where potential dilution (as defined below) is no greater than 10%.

We will vote on a case-by-casebasis on the following issues:

•

Shareholder proposals seeking additional disclosure of executive and director pay information.

•

Executive and director stock-related compensation plans. We will consider the following factors when reviewing these plans:

•

The program must be of a reasonable size. We will approve plans where the combined employee and director plans together would generate less than 15% dilution. We will reject plans with 15% or more potential dilution.

Dilution = (A + B + C) / (A + B + C + D), where

A = Shares reserved for plan/amendment,

B = Shares available under continuing plans,

C = Shares granted but unexercised and

D = Shares outstanding.

•

The plan must not:

•

Explicitly permit unlimited option repricing authority or have allowed option repricing in the past without shareholder approval.

•

Be a self-replenishing "evergreen" plan or a plan that grants discount options and tax offset payments.

•

We are generally in favor of proposals that increase participation beyond executives.

•

We generally support proposals asking companies to adopt rigorous vesting provisions for stock option plans such as those that vest incrementally over, at least, a three- or four-year period with a pro rata portion of the shares becoming exercisable on an annual basis following grant date.

•

We generally support proposals asking companies to disclose their window period policies for stock transactions. Window period policies ensure that employees do not exercise options based on insider information contemporaneous with quarterly earnings releases and other material corporate announcements.

•

We generally support proposals asking companies to adopt stock holding periods for their executives.

•

All other employee stock purchase plans.

•

All other compensation-related proposals, including deferred compensation plans, employment agreements, loan guarantee programs and retirement plans.

•

All other proposals regarding stock compensation plans, including extending the life of a plan, changing vesting restrictions, repricing options, lengthening exercise periods or accelerating distribution of awards and pyramiding and cashless exercise programs.

We will vote against:

•

Pensions for non-employeedirectors. We believe these retirement plans reduce director objectivity.

•

Elimination of stock option plans.

We will vote on a case-bycase basis on these issues:

•

Limits on executive and director pay.

•

Stock in lieu of cash compensation for directors.

Corporate Governance

Amundi US will vote for:

•

Confidential voting.

•

Equal access provisions, which allow shareholders to contribute their opinions to proxy materials.

•

Proposals requiring directors to disclose their ownership of shares in the company.

We will vote on a case-by-casebasis on the following issues:

•

Change in the state of incorporation. We will support reincorporations 16 supported by valid business reasons. We will oppose those that appear to be solely for the purpose of strengthening takeover defenses.

•

Bundled proposals. We will evaluate the overall impact of the proposal.

•

Adopting or amending the charter, bylaws or articles of association.

•

Shareholder appraisal rights, which allow shareholders to demand judicial review of an acquisition price.

We will vote against:

•

Shareholder advisory committees. While management should solicit shareholder input, we prefer to leave the method of doing so to management's discretion.

•

Limitations on stock ownership or voting rights.

•

Reduction in share ownership disclosure guidelines.

Mergers and Restructurings

Amundi US will vote on the following and similar issues on a case-by-casebasis:

•

Mergers and acquisitions.

•

Corporate restructurings, including spin-offs, liquidations, asset sales, joint ventures, conversions to holding company and conversions to self-managed REIT structure.

•

Debt restructurings.

•

Conversion of securities.

•

Issuance of shares to facilitate a merger.

•

Private placements, warrants, convertible debentures.

•

Proposals requiring management to inform shareholders of merger opportunities.

We will normally vote against shareholder proposals requiring that the company be put up for sale.

Investment Companies

Many of our portfolios may invest in shares of closed-endfunds or open-endfunds (including exchange-traded funds). The non-corporatestructure of these investments raises several unique proxy voting issues.

Amundi US will vote for:

•

Establishment of new classes or series of shares.

•

Establishment of a master-feeder structure.

Amundi US will vote on a case-by-casebasis on:

•

Changes in investment policy. We will normally support changes that do not affect the investment objective or overall risk level of the fund. We will examine more fundamental changes on a case-by-casebasis.

•

Approval of new or amended advisory contracts.

•

Changes from closed-endto open-endformat.

•

Election of a greater number of independent directors.

•

Authorization for, or increase in, preferred shares.

•

Disposition of assets, termination, liquidation, or mergers.

•

Classified boards of closed-endfunds, but will typically support such proposals.

In general, business development companies (BDCs) are not considered investment companies for these purposes but are treated as corporate issuers.

Environmental and Social Issues

Amundi US believes that environmental and social issues may influence corporate performance and economic return. Indeed, by analyzing all of a company's risks and opportunities, Amundi US can better assess its intrinsic value and long-term economic prospects.

When evaluating proxy proposals relating to environmental or social issues, decisions are made on a case-by-casebasis. We consider each of these proposals based on the impact to the company's shareholders and economic return, the specific circumstances at each individual company, any potentially adverse economic concerns, and the current policies and practices of the company.

For example, shareholder proposals relating to environmental and social issues, and on which we will vote on a base-by-casebasis, may include those seeking that a company:

•

Conduct studies regarding certain environmental or social issues;

•

Study the feasibility of the company taking certain actions with regard to such issues; or

•

Take specific action, including adopting or ceasing certain behavior and adopting company standards and principles, in relation to such issues.

In general, Amundi US believes these issues are important and should receive management attention. Amundi US will support proposals where we believe the proposal, if implemented, would improve the prospects for the long-term success of the business and would provide value to the company and its shareholders. Amundi US may abstain on shareholder proposals with regard to environmental and social issues in cases where we believe the proposal, if implemented, would not be in the economic interests of the company, or where implementing the proposal would constrain management flexibility or would be unduly difficult, burdensome or costly.

When evaluating proxy proposals relating to environmental or social issues, Amundi US may consider the following factors or other factors deemed relevant, given such weight as deemed appropriate:

•

approval of the proposal helps improve the company's practices;

•

approval of the proposal can improve shareholder value;

•

the company's current stance on the topic is likely to have negative effects on its business position or reputation in the short, medium, or long term;

•

the company has already put appropriate action in place to respond to the issue contained in the proposal;

•

the company's reasoning against approving the proposal responds appropriately to the various points mentioned by the shareholder when the proposal was presented;

•

the solutions recommended in the proposal are relevant and appropriate, and if the topic of the proposal would not be better addressed through another means.

In the event of failures in risk management relating to environmental and social issues, Amundi US may vote against the election of directors responsible for overseeing those areas. Issues of special concern to Amundi US include corporate commitments to mitigating climate effects; achieving a diverse board of directors and employee base; And maintaining sound and safe working conditions, equitable compensation practices, and opportunities for career advancement. Amundi US will vote against proposals calling for substantial changes in the company's business or activities. We will also normally vote against proposals with regard to contributions, believing that management should control the routine disbursement of funds. In each case, fundamental consideration governing votes cast on behalf of any of the Pioneer Funds in these areas is Amundi US' assessment of the potential impact on shareholder value.

Conflicts of Interest

Amundi US recognizes that in certain circumstances a conflict of interest may arise when Amundi US votes a proxy.

A conflict of interest occurs when Amundi US' interests interfere, or appear to interfere, with the interests of Amundi US' clients.

A conflict may be actual or perceived and may exist, for example, when the matter to be voted on concerns:

•

An affiliate of Amundi US, such as another company belonging to the Credit Agricole banking group ( "Credit Agricole Affiliate");

•

An issuer of a security for which Amundi US acts as a sponsor, advisor, manager, custodian, distributor, underwriter, broker, or other similar capacity (including those securities specifically declared by its parent Amundi to present a conflict of interest for Amundi US);

•

An issuer of a security for which Amundi has informed Amundi US that a Credit Agricole Affiliate acts as a sponsor, advisor, manager, custodian, distributor, underwriter, broker, or other similar capacity; or

•

A person with whom Amundi US (or any of its affiliates) has an existing, material contract or business relationship.

Any member of the Proxy Voting Oversight Group and any other associate involved in the proxy voting process with knowledge of any apparent or actual conflict of interest must disclose such conflict to the Proxy Coordinator and the Chief Compliance Officer of Amundi US and the Funds. If any associate is lobbied or pressured with respect to any voting decision, whether within or outside of Amundi US, he or she should contact a member of the Proxy Voting Oversight Group or Amundi US' Chief Compliance Officer.

The Proxy Voting Oversight Group will review each item referred to Amundi US by the proxy voting service to determine whether an actual or potential conflict of interest exists in connection with the proposal(s) to be voted upon. The review will be conducted by comparing the apparent parties affected by the proxy proposal being voted upon against the Controller's and Compliance Department's internal list of interested persons and, for any matches found, evaluating the anticipated magnitude and possible probability of any conflict of interest being present. The Proxy Voting Oversight Group may cause any of the following actions to be taken when a conflict of interest is present:

•

Vote the proxy in accordance with the vote indicated under "Voting Guidelines," if a vote is indicated, or

•

Direct the independent proxy voting service to vote the proxy in accordance with its independent assessment or that of another independent adviser appointed by Amundi US or the applicable client for this purpose.

If the Proxy Voting Oversight Group perceives a material conflict of interest, the Group may also choose to disclose the conflict to the affected clients and solicit their consent to proceed with the vote or their direction (including through a client's fiduciary or other adviser), or may take such other action in good faith (in consultation with counsel) that would protect the interests of clients.

For each referral item, the determination regarding the presence or absence of any actual or potential conflict of interest will be documented in a Conflicts of Interest Report prepared by the Proxy Coordinator.

The Proxy Voting Oversight Group will review periodically the independence of the proxy voting service. This may include a review of the service's conflict management procedures and other documentation and an evaluation as to whether the service continues to have the competency and capacity to vote proxies.

Decisions Not to Vote Proxies

Although it is Amundi US' general policy to vote all proxies in accordance with the principles set forth in this policy, there may be situations in which the Proxy Voting Oversight Group does not vote a proxy referred to it. For example, because of the potential conflict of interest inherent in voting shares of a Credit Agricole Affiliate, Amundi US will abstain from voting the shares unless otherwise directed by a client. In such a case, the Proxy Coordinator will inform Amundi Compliance before exercising voting rights.

There exist other situations in which the Proxy Voting Oversight Group may refrain from voting a proxy. For example, if the cost of voting a foreign security outweighs the benefit of voting, the Group may not vote the proxy. The Group may not be given enough time to process a vote, perhaps because its receives a meeting notice too late or it cannot obtain a translation of the agenda in the time available. If Amundi US has outstanding "sell" orders, the proxies for shares subject to the order may not be voted to facilitate the sale. Although Amundi US may hold shares on a company's record date, if the shares are sold prior to the meeting date the Group may decide not to vote those shares.

Recordkeeping

The Proxy Coordinator shall ensure that Amundi US' proxy voting service:

•

Retains a copy of each proxy statement received (unless the proxy statement is available from the SEC's Electronic Data Gathering, Analysis, and Retrieval (EDGAR) system);

•

Retains a record of the vote cast;

•

Prepares Form N-PXfor filing on behalf of each client that is a registered investment company; and

•

Is able to promptly provide Amundi US with a copy of the voting record upon its request.

The Proxy Coordinator shall ensure that for those votes that may require additional documentation (i.e. conflicts of interest, exception votes and case-by-casevotes) the following records are maintained:

•

A record memorializing the basis for each referral vote cast;

•

A copy of any document created by Amundi US that was material in making the decision on how to vote the subject proxy;

•

A copy of any recommendation or analysis furnished by the proxy voting service; and

•

A copy of any conflict notice, conflict consent or any other written communication (including emails or other electronic communications) to or from the client (or in the case of an employee benefit plan, the plan's trustee or other fiduciaries) regarding the subject proxy vote cast by, or the vote recommendation of, Amundi US.

Amundi US shall maintain the above records in the client's file in accordance with applicable regulations. Copies of this policy, and copies of records related to this policy shall be kept in accordance with Amundi US' Books and Records Policy. This policy and procedure shall be periodically reviewed and updated consistent with the requirements and standards established by Amundi US.

Escalation and Management Reporting

Escalation

It is each associate's responsibility to contact his or her business unit head, the Proxy Coordinator, a member of the Proxy Voting Oversight Group or Amundi US' Chief Compliance Officer if he or she becomes aware of any possible noncompliance with this policy.

Management Reporting

Reporting is done to senior leadership on an as needed basis.

Training

Amundi US will conduct periodic training regarding proxy voting and this policy. It is the responsibility of the business line policy owner and the applicable Compliance Department to coordinate and conduct such training.
