These fees were billed to the registrant or 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 ("control affiliates"). The nature of the services provided was related to a software licensing fee.

The nature of the services comprising all other fees is advisory services provided to the investment manager. These fees were approved by the registrant's audit committee.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

The trust's Audit Committee must pre-approve all audit and non-audit services provided by the independent registered public accounting firm (the "Auditor") relating to the operations or financial reporting of the funds. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The trust's Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee's consideration of audit-related and non-audit services by the Auditor. The policies and procedures require that any audit-related and non-audit service provided by the Auditor and any non-audit service provided by the Auditor to a fund service provider that relates directly to the operations and financial reporting of a fund are subject to approval by the Audit Committee before such service is provided. Audit-related services provided by the Auditor that are expected to exceed $25,000 per instance/per fund are subject to specific pre-approval by the Audit Committee. Tax services provided by the Auditor that are expected to exceed $30,000 per instance/per fund are subject to specific pre-approval by the Audit Committee.

All audit services, as well as the audit-related and non-audit services that are expected to exceed the amounts stated above, must be approved in advance of provision of the service by formal resolution of the Audit Committee. At the regularly scheduled Audit Committee meetings, the Committee reviews a report summarizing the services, including fees, provided by the Auditor.

(e)(2) Services approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X: Audit-Related Fees, Tax Fees and All Other Fees:

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception under Rule 2-01 of Regulation S-X.

(f)According to the registrant's principal accountant, for the fiscal year ended December 31, 2023, the percentage of hours spent on the audit of the registrant's financial statements for the most recent fiscal year that were attributed to work performed by persons who were not full-time, permanent employees of principal accountant was less than 50%.

(g)The aggregate non-audit fees billed by the registrant's accountant(s) for services rendered to the registrant and rendered to the registrant's control affiliates for each of the last two fiscal years of the registrant were $1,370,062 for the fiscal year ended December 31, 2023 and $1,328,389 for the fiscal year ended December 31, 2022.

(h)The audit committee of the registrant has considered the non-audit services provided by the registrant's principal accountant(s) to the control affiliates and has determined that the services that were not pre-approved are compatible with maintaining the principal accountant(s)' independence.

(i)Not applicable.

(j)Not applicable.

Other Accounts the Portfolio Managers are Managing

The table below indicates, for each portfolio manager, information about the accounts over which the portfolio manager has day-to-day investment responsibility. All information on the number of accounts and total assets in the table is as of December 31, 2023. For purposes of the table, "Other Pooled Investment Vehicles" may include investment partnerships and group trusts, and "Other Accounts" may include separate accounts for institutions or individuals, insurance company general or separate accounts, pension funds and other similar institutional accounts.

Accounts within the total accounts that are subject to a performance-based advisory fee: 0.

Conflicts of Interest. When a portfolio manager is responsible for the management of more than one account, the potential arises for the portfolio manager to favor one account over another. The principal types of potential conflicts of interest that may arise are discussed below. For the reasons outlined below, the Fund does not believe that any material conflicts are likely to arise out of a portfolio manager's responsibility for the management of the Fund as well as one or more other accounts. The Advisor and Subadvisor have adopted procedures that are intended to monitor compliance with the policies referred to in the following paragraphs. Generally, the risks of such conflicts of interests are increased to the extent that a portfolio manager has a financial

incentive to favor one account over another. The Advisor and Subadvisor have structured their compensation arrangements in a manner that is intended to limit such potential for conflicts of interests. See "Compensation of Portfolio Managers" below.

•A portfolio manager could favor one account over another in allocating new investment opportunities that have limited supply, such as initial public offerings and private placements. If, for example, an initial public offering that was expected to appreciate in value significantly shortly after the offering was allocated to a single account, that account may be expected to have better investment performance than other accounts that did not receive an allocation on the initial public offering. The Subadvisor has policies that require a portfolio manager to allocate such investment opportunities in an equitable manner and generally to allocate such investments proportionately among all accounts with similar investment objectives.

•A portfolio manager could favor one account over another in the order in which trades for the accounts are placed. If a portfolio manager determines to purchase a security for more than one account in an aggregate amount that may influence the market price of the security, accounts that purchased or sold the security first may receive a more favorable price than accounts that made subsequent transactions. The less liquid the market for the security or the greater the percentage that the proposed aggregate purchases or sales represent of average daily trading volume, the greater the potential for accounts that make subsequent purchases or sales to receive a less favorable price. When a portfolio manager intends to trade the same security for more than one account, the policies of the Subadvisor generally require that such trades be "bunched," which means that the trades for the individual accounts are aggregated and each account receives the same price. There are some types of accounts as to which bunching may not be possible for contractual reasons (such as directed brokerage arrangements). Circumstances may also arise where the trader believes that bunching the orders may not result in the best possible price. Where those accounts or circumstances are involved, the Subadvisor will place the order in a manner intended to result in as favorable a price as possible for such client.

•A portfolio manager could favor an account if the portfolio manager's compensation is tied to the performance of that account rather than all accounts managed by the portfolio manager. If, for example, the portfolio manager receives a bonus based upon the performance of certain accounts relative to a benchmark while other accounts are disregarded for this purpose, the portfolio manager will have a financial incentive to seek to have the accounts that determine the portfolio manager's bonus achieve the best possible performance to the possible detriment of other accounts. Similarly, if the Subadvisor receives a performance-based advisory fee, the portfolio manager may favor that account, whether or not the performance of that account directly determines the portfolio manager's compensation. The investment performance on specific accounts is not a factor in determining the portfolio manager's compensation. See "Compensation of Portfolio Managers" below. Neither the Advisor nor the Subadvisor receives a performance-based fee with respect to any of the accounts managed by the portfolio managers.

•A portfolio manager could favor an account if the portfolio manager has a beneficial interest in the account, in order to benefit a large client or to compensate a client that had poor returns. For example, if the portfolio manager held an interest in an investment partnership that was one of the accounts managed by the portfolio manager, the portfolio manager would have an economic incentive to favor the account in which the portfolio manager held an interest. The Subadvisor imposes certain trading restrictions and reporting requirements for accounts in which a portfolio manager or certain family

members have a personal interest in order to confirm that such accounts are not favored over other accounts.

•If the different accounts have materially and potentially conflicting investment objectives or strategies, a conflict of interest may arise. For example, if a portfolio manager purchases a security for one account and sells the same security short for another account, such trading pattern could disadvantage either the account that is long or short. In making portfolio manager assignments, the Subadvisor seeks to avoid such potentially conflicting situations. However, where a portfolio manager is responsible for accounts with differing investment objectives and policies, it is possible that the portfolio manager will conclude that it is in the best interest of one account to sell a portfolio security while another account continues to hold or increase the holding in such security.

Compensation of Portfolio Managers. The Subadvisor has adopted a system of compensation for portfolio managers and others involved in the investment process that is applied systematically among investment professionals. At the Subadvisor, the structure of compensation of investment professionals is currently composed of the following basic components: base salary and short- and long-term incentives. The following describes each component of the compensation package for the individuals identified as a portfolio manager for the Funds.

•Base salary. Base compensation is fixed and normally reevaluated on an annual basis. The Subadvisor seeks to set compensation at market rates, taking into account the experience and responsibilities of the investment professional.

•Incentives. Only investment professionals are eligible to participate in the short-and long-term incentive plan. Under the plan, investment professionals are eligible for an annual cash award. The plan is intended to provide a competitive level of annual bonus compensation that is tied to the investment professional achieving superior investment performance and aligns the financial incentives of the Subadvisor and the investment professional. Any bonus under the plan is completely discretionary, with a maximum annual bonus that may be well in excess of base salary. Payout of a portion of this bonus may be deferred for up to five years. While the amount of any bonus is discretionary, the following factors are generally used in determining bonuses under the plan:

•Investment Performance: The investment performance of all accounts managed by the investment professional over one, three and five-year periods are considered. With respect to fixed income accounts, relative yields are also used to measure performance. The pre-tax performance of each account is measured relative to an appropriate benchmark and universe as identified in the table below.

•Financial Performance: The profitability of the Subadvisor and its parent company are also considered in determining bonus awards.

•In addition to the above, compensation may also include a revenue component for an investment team derived from a number of factors including, but not limited to client assets under management, investment performance, and firm metrics.

•Manulife Equity Awards. A limited number of senior investment professionals may receive options to purchase shares of Manulife Financial stock. Generally, such option would permit the investment professional to purchase a set amount of stock at the market price on the date of grant. The option can be exercised for a set period (normally a number of years or until termination of employment) and the investment

professional would exercise the option if the market value of Manulife Financial stock increases. Some investment professionals may receive restricted stock grants, where the investment professional is entitled to receive the stock at no or nominal cost, provided that the stock is forgone if the investment professional's employment is terminated prior to a vesting date.

•Deferred Incentives. Investment professionals may receive deferred incentives which are fully invested in strategies managed by the team/individuals as well as other Manulife Asset Management strategies.

The Subadvisor also permits investment professionals to participate on a voluntary basis in a deferred compensation plan, under which the investment professional may elect on an annual basis to defer receipt of a portion of their compensation until retirement. Participation in the plan is voluntary.

Share Ownership by Portfolio Managers. For purposes of these tables, "similarly managed accounts" include all accounts that are managed (i) by the same portfolio managers that are jointly and primarily responsible for the day-to-day management of the Fund; and (ii) with an investment style, objective, policies and strategies substantially similar to those that are used to manage the Fund.

(d) Exhibit 99. CONSENT - Consent of Independent Registered Public Accounting Firm

SIGNATURES

Pursuant to the requirements of the Securities Exchange Act of 1934 and the Investment Company Act of 1940, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.

John Hancock Financial Opportunities Fund

Pursuant to the requirements of the Securities Exchange Act of 1934 and the Investment Company Act of 1940, this report has been signed below by the following persons on behalf of the registrant and in the capacities and on the dates indicated.

Each of the Covered Officers should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

II.Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest Overview

A "conflict of interest" occurs when a Covered Officer's private interest interferes with the interests of, or his service to, the Fund. For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position with the Fund. Certain conflicts of interest arise out of the relationships between the Covered Officers and the Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940, as amended (the "Investment Company Act") and the Investment Advisers Act of 1940, as amended (the "Investment Advisers Act"). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as "affiliated persons" of the Fund. Each of the Covered Officers is an officer or employee of the investment adviser or a service provider ("Service Provider") to the Fund. The Fund's, the investment adviser's and the Service Provider's compliance programs and procedures are designed to prevent, or identify and correct, violations of these provisions. This Code does not, and is not intended to, repeat or replace these programs and procedures, and such conflicts fall outside of the parameters of this Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Fund and the investment adviser and the Service Provider of which the Covered Officers are also officers or employees. As a result, this Code recognizes that the Covered Officers will, in the normal course of their duties (whether formally for the Fund, for the investment adviser or for the Service Provider), be involved in establishing policies and implementing decisions which will have different effects on the investment adviser, the Service Provider and the Fund. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Fund and the investment adviser and the Service Provider and is consistent with the performance by the Covered Officers of their duties as officers of the Fund. Thus, if such participation is performed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, it will be deemed to have been handled ethically. In addition, it is recognized by the Fund's Board of Trustees/Directors (the "Board") that the Covered Officers may also be officers or employees of one or more other investment companies covered by other Codes.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act. The following list provides examples of conflicts of interest under the Code, but the Covered Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of a Covered Officer should not be placed improperly before the interest of the Fund.

***

2 of 6

Each Covered Officer must:

not use his/her personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Fund whereby the Covered Officer would benefit personally to the detriment of the Fund;

not cause the Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than for the benefit of the Fund; and

not use material non-public knowledge of portfolio transactions made or contemplated for the Fund to trade personally or cause others to trade personally in contemplation of the market effect of such transactions.

Additionally, conflicts of interest may arise in other situations, the propriety of which may be discussed, if material, with the Fund's Chief Compliance Officer ("CCO"). Examples of these include:

serve as a director/trustee on the board of any public or private company;

the receipt of any non-nominal gifts;

the receipt of any entertainment from any company with which the Fund has current or prospective business dealings unless such entertainment is business-related, reasonable in cost, appropriate as to time and place, and not so frequent as to raise any question of impropriety (or other formulation as the Fund already uses in another code of conduct);

any ownership interest in, or any consulting or employment relationship with, any of the Fund's service providers, other than its investment adviser, any sub-adviser, principal underwriter, administrator or any affiliated person thereof; and

a direct or indirect financial interest in commissions, transaction charges or spreads paid by the Fund for effecting portfolio transactions or for selling or redeeming shares other than an interest arising from the Covered Officer's employment, such as compensation or equity ownership.

III.Disclosure & Compliance

Each Covered Officer should familiarize himself or herself with the disclosure requirements generally applicable to the Fund;

Each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Fund to others, whether within or outside the Fund, including to the Fund's directors and auditors, and to governmental regulators and self- regulatory organizations;

3 of 6

Each Covered Officer should, to the extent appropriate within his/her area of responsibility, consult with other officers and employees of the Fund and the Fund's adviser or any sub-adviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fund files with, or submits to, the SEC and in other public communications made by the Fund; and

It is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

IV. Reporting & Accountability

Each Covered Officer must:

upon adoption of the Code (or thereafter as applicable, upon becoming an Covered Officer), affirm in writing to the Fund's CCO that he/she has received, read, and understands the Code;

annually thereafter affirm to the Fund's CCO that he/she has complied with the requirements of the Code;

not retaliate against any employee or Covered Officer or their affiliated persons for reports of potential violations that are made in good faith;

notify the Fund's CCO promptly if he/she knows of any violation of this Code (Note: failure to do so is itself a violation of this Code); and

report at least annually any change in his/her affiliations from the prior year.

The Fund's CCO is responsible for applying this Code to specific situations in which questions are presented under it and has the authority to interpret this Code in any particular situation. However, any approvals or waivers sought by the Principal Executive Officer will be considered by the Fund's Board or the Compliance Committee thereof (the "Committee").

The Fund will follow these procedures in investigating and enforcing this Code:

the Fund's CCO will take all appropriate action to investigate any potential violations reported to him/her;

if, after such investigation, the CCO believes that no violation has occurred, the CCO is not required to take any further action;

any matter that the CCO believes is a violation will be reported to the Board or, if applicable, Compliance Committee;

if the Board or, if applicable, Compliance Committee concurs that a violation has occurred, the Board, either upon its determination of a violation or upon

4 of 6

recommendation of the Compliance Committee, if applicable, will consider appropriate action, which may include review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the Service Provider or the investment adviser or its board; or a recommendation to dismiss the Registrant's Executive Officer;

the Board, or if applicable the Compliance Committee, will be responsible for granting waivers, as appropriate; and

any changes to or waivers of this Code will, to the extent required, be disclosed as provided by SEC rules.

V.Other Policies & Procedures

This Code shall be the sole code of ethics adopted by the Fund for purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered investment companies thereunder. Insofar as other policies or procedures of the Fund, the Fund's adviser, any sub- adviser, principal underwriter or other service providers govern or purport to govern the behavior or activities of the Covered Officers who are subject to this Code, they are superseded by this Code to the extent that they overlap or conflict with the provisions of this Code. The Fund's and its investment adviser's codes of ethics under Rule 204A-1 under the Investment Advisers Act and Rule 17j-1 under the Investment Company Act, respectively, are separate requirements applying to the Covered Officers and others and are not part of this Code.

VI. Amendments

Any amendments to this Code, other than amendments to Exhibit A, must be approved or ratified by a majority vote of the Fund's Board, including a majority of independent directors.

VII. Confidentiality

All reports and records prepared or maintained pursuant to this Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Code, such matters shall not be disclosed to anyone other than the Fund's Board and its counsel, the investment adviser and the relevant Service Providers.

VIII. Internal Use

The Code is intended solely for the internal use by the Fund and does not constitute an admission, by or on behalf of the Fund, as to any fact, circumstance, or legal conclusion.

Executive summary

Each investment team at Manulife Investment Management (Manulife IM)1 is responsible for investing in line with its investment philosophy and clients' objectives. Manulife IM's approach to proxy voting aligns with its organizational structure and encourages best practices in governance and management of environmental and social risks and opportunities. Manulife IM has adopted and implemented proxy voting policies and procedures to ensure that proxies are voted in the best interests of its clients for whom it has proxy voting authority.

This global proxy voting policy and procedures (policy) applies to each of the Manulife IM advisory affiliates listed in Appendix A. In seeking to adhere to local regulatory requirements of the jurisdiction in which an advisory affiliate operates, additional procedures specific to that affiliate may be implemented to ensure compliance, where applicable. The policy is not intended to cover every possible situation that may arise in the course of business, but rather to act as a decision-making guide. It is therefore subject to change and interpretation from time to time as facts and circumstances dictate.

Statement of policy

•The right to vote is a basic component of share ownership and is an important control mechanism to ensure that a company is managed in the best interests of its shareholders. Where clients delegate proxy voting authority to Manulife IM, Manulife IM has a fiduciary duty to exercise voting rights responsibly.

•Where Manulife IM is granted and accepts responsibility for voting proxies for client accounts, it will seek to ensure proxies are received and voted in the best interests of the client with a view to maximize the economic value of their equity securities unless it determines that it is in the best interests of the client to refrain from voting a given proxy.

•If there is any potential material proxy-related conflict of interest between Manulife IM and its clients, identification and resolution processes are in place to provide for determination in the best interests of the client.

•Manulife IM will disclose information about its proxy voting policies and procedures to its clients.

•Manulife IM will maintain certain records relating to proxy voting.

1Manulife Investment Management is the unified global brand for Manulife's global wealth and asset management business, which serves individual investors and institutional clients in three businesses: retirement, retail, and institutional asset management (Public markets and private markets).

Philosophy on sustainable investing

Manulife IM's commitment to sustainable investment2 is focused on protecting and enhancing the value of our clients' investments and, as active owners in the companies in which we invest, we believe that voting at shareholder meetings can contribute to the long-term sustainability of our investee companies. Manulife IM will seek to exercise the rights and responsibilities associated with equity ownership, on behalf of its clients, with a focus on maximizing long-term shareholder returns, as well as enhancing and improving the operating strength of the companies to create sustainable value for shareholders.

Manulife IM invests in a wide range of securities across the globe, ranging from large multinationals to smaller early-stage companies, and from well-developed markets to emerging and frontier markets. Expectations of those companies vary by market to reflect local standards, regulations, and laws. Manulife IM believes, however, that successful companies across regions are generally better positioned over the long term if they have:

•Robust oversight, including a strong and effective board with independent and objective leaders working on behalf of shareholders;

•Mechanisms to mitigate risk such as effective internal controls, board expertise covering a firm's unique risk profile, and routine use of key performance indicators to measure and assess long-term risks;

•A management team aligned with shareholders through remuneration structures that incentivize long- term performance through the judicious and sustainable stewardship of company resources;

•Transparent and thorough reporting of the components of the business that are most significant to shareholders and stakeholders with focus on the firm's long-term success; and

•Management focused on all forms of capital, including environmental, social, and human capital.

The Manulife Investment Management voting principles (voting principles) outlined in Appendix B provide guidance for our voting decisions. An active decision to invest in a firm reflects a positive conviction in the investee company and we generally expect to be supportive of management for that reason. Manulife IM may seek to challenge management's recommendations, however, if they contravene these voting principles or Manulife IM otherwise determines that doing so is in the best interest of its clients.

Manulife IM also regularly engages with boards and management on environmental, social, or corporate governance issues consistent with the principles stipulated in our sustainable investing statement and our ESG

engagement policy. Manulife IM may, through these engagements, request certain changes of the portfolio company to mitigate risks or maximize opportunities. In the context of preparing for a shareholder meeting, Manulife IM will review progress on requested changes for those companies engaged. In an instance where Manulife IM determines that the issuer has not made sufficient improvements on an issue, then we may take voting action to demonstrate our concerns.

In rare circumstances, Manulife IM may consider filing, or co-filing, a shareholder resolution at an investee company. This may occur where our team has engaged with management regarding a material sustainability risk or opportunity, and where we determine that the company has not made satisfactory progress on the matter within a reasonable time period. Any such decision will be in the sole discretion of Manulife IM and acted on where we believe filing, or co-filing, a proposal is in the best interests of our clients.

Manulife IM may also divest of holdings in a company where portfolio managers are dissatisfied with company financial performance, strategic direction, and/or management of material sustainability risks or opportunities.

Procedures

Receipt of ballots and proxy materials

Proxies received are reconciled against the client's holdings, and the custodian bank will be notified if proxies have not been forwarded to the proxy service provider when due.

Voting proxies

Manulife IM has adopted the voting principles contained in Appendix B of this policy.

Manulife IM has deployed the services of a proxy voting services provider to ensure the timely casting of votes, and to provide relevant and timely proxy voting research to inform our voting decisions. Through this process, the proxy voting services provider populates initial recommended voting decisions that are aligned with the Manulife IM voting principles outlined in Appendix B. These voting recommendations are then submitted, processed, and ultimately tabulated. Manulife IM retains the authority and operational functionality to submit different voting instructions after these initial recommendations from the proxy voting services provider have been submitted, based on Manulife IM's assessment of each situation. As Manulife IM reviews voting recommendations and decisions, as articulated below, Manulife IM will often change voting instructions based on those reviews. Manulife IM periodically reviews the detailed policies created by the proxy voting service provider to ensure consistency with our voting principles, to the extent this is possible.

Manulife IM also has procedures in place to review additional materials submitted by issuers often in response to voting recommendations made by proxy voting service providers. Manulife IM will review additional materials related to proxy voting decisions in those situations where Manulife IM becomes aware of those additional materials, is considering voting contrary to management, and where Manulife IM owns 2% or more of the subject issuer as aggregated across the funds.

INTERNAL

Manulife Investment Management global proxy voting policy and procedures

Portfolio managers actively review voting options and make voting decisions for their holdings. Where Manulife IM holds a significant ownership position in an issuer, the rationale for a portfolio manager's voting decision is specifically recorded, including whether the vote cast aligns with the recommendations of the proxy voting services provider or has been voted differently. A significant ownership position in an investment is defined as those cases where Manulife IM holds at least 2% of a company's issued share capital in aggregate across all Manulife IM client accounts.

The Manulife IM ESG research and integration team (ESG team) is an important resource for portfolio management teams on proxy matters. This team provides advice on specific proxy votes for individual issuers if needed. ESG team advice is supplemental to the research and recommendations provided by our proxy voting services provider. In particular, ESG analysts actively review voting resolutions for companies in which:

•Manulife IM's aggregated holdings across all client accounts represent 2% or greater of issued capital;

•A meeting agenda includes shareholder resolutions related to environmental and social risk management issues, or where the subject of a shareholder resolution is deemed to be material to our investment decision; or

Manulife IM may also review voting resolutions for issuers where an investment team engaged with the firm within the previous two years to seek a change in behavior.

After review, the ESG team may provide research and advice to investment staff in line with the voting principles.

Manulife IM also has an internal proxy voting working group (working group) comprising senior managers from across Manulife IM including the equity investment team, legal, compliance, and the ESG team. The working Group operates under the auspices of the Manulife IM Public Markets Sustainable Investing Committee. The Working group regularly meets to review and discuss voting decisions on shareholder proposals or instances where a portfolio manager recommends a vote different than the recommendation of the proxy voting services provider.

Manulife IM clients retain the authority and may choose to lend shareholdings. Manulife IM, however, generally retains the ability to restrict shares from being lent and to recall shares on loan in order to preserve proxy voting rights. Manulife IM is focused in particular on preserving voting rights for issuers where funds hold 2% or more of an issuer as aggregated across funds. Manulife IM has a process in place to systematically restrict and recall shares on a best efforts basis for those issuers where we own an aggregate of 2% or more.

Manulife IM may refrain from voting a proxy where we have agreed with a client in advance to limit the situations in which we will execute votes. Manulife IM may also refrain from voting due to logistical considerations that may have a detrimental effect on our ability to vote. These issues may include, but are not limited to:

•Costs associated with voting the proxy exceed the expected benefits to clients;

April 2021 5

INTERNAL

Manulife Investment Management global proxy voting policy and procedures

•Underlying securities have been lent out pursuant to a client's securities lending program and have not been subject to recall;

•Short notice of a shareholder meeting;

•Requirements to vote proxies in person;

•Restrictions on a nonnational's ability to exercise votes, determined by local market regulation;

•Restrictions on the sale of securities in proximity to the shareholder meeting (i.e., share blocking);

•Requirements to disclose commercially sensitive information that may be made public (i.e., reregistration);

•Requirements to provide local agents with power of attorney to facilitate the voting instructions (such proxies are voted on a best-efforts basis); or

•The inability of a client's custodian to forward and process proxies electronically.

If a Manulife IM portfolio manager believes it is in the best interest of a client to vote proxies in a manner inconsistent with the policy, the portfolio manager will submit new voting instructions to a member of the ESG team with rationale for the new instructions. The ESG team will then support the portfolio manager in developing voting decision rationale that aligns with this policy and the voting principles. The ESG team will then submit the vote change to the working group. The working group will review the change and ensure that the rationale is sound, and the decision will promote the long-term success of the issuer.

On occasion, there may be proxy votes that are not within the research and recommendation coverage universe of the proxy voting service provider. Portfolio managers responsible for the proxy votes will provide voting recommendations to the ESG team, and those items may be escalated to the working group for review to ensure that the voting decision rationale is sound, and the decision will promote the long-term success of the issuer. the Manulife IM proxy operations team will be notified of the voting decisions and execute the votes accordingly.

Manulife IM does not engage in the practice of "empty voting" (a term embracing a variety of factual circumstances that result in a partial, or total, separation of the right to vote at a shareholders meeting from beneficial ownership of the shares on the meeting date). Manulife IM prohibits investment managers from creating large hedge positions solely to gain the vote while avoiding economic exposure to the market. Manulife IM will not knowingly vote borrowed shares (for example, shares borrowed for short sales and hedging transactions).

Engagement of the proxy voting service provider

Manulife IM has contracted with a third-party proxy service provider to assist with the proxy voting process. Except in instances where a client retains voting authority, Manulife IM will instruct custodians of client accounts to forward all proxy statements and materials received in respect of client accounts to the proxy service provider.

Manulife IM has engaged its proxy voting service provider to:

•Research and make voting recommendations;

•Ensure proxies are voted and submitted in a timely manner;

•Provide alerts when issuers file additional materials related to proxy voting matters;

•Perform other administrative functions of proxy voting;

•Maintain records of proxy statements and provide copies of such proxy statements promptly upon request;

•Maintain records of votes cast; and

•Provide recommendations with respect to proxy voting matters in general.

Scope of proxy voting authority

Manulife IM and our clients shape the proxy voting relationship by agreement provided there is full and fair disclosure and informed consent. Manulife IM may agree with clients to other proxy voting arrangements in which Manulife IM does not assume proxy voting responsibility or will only vote in limited circumstances.3

While the application of our fiduciary duty in the context of proxy voting will vary with the scope of the voting authority we assume, we acknowledge the relationship in all cases remains that of a fiduciary to the client. Beyond the general discretion retained by Manulife IM to withhold from voting as outlined above, Manulife IM may enter a specific agreement with a client not to exercise voting authority on certain matters where the cost of voting would be high or the benefit to the client would be low.

Disclosure of proxy votes

Manulife IM may inform company management of our voting intentions ahead of casting the vote. This is in line with Manulife IM's objective to provide the opportunity for companies to better understand our investment process, policies, and objectives.

We will not intentionally disclose to anyone else, including other investors, our voting intention prior to casting the vote.

Manulife IM keeps records of proxy voting available for inspection by clients, regulatory authorities, or government agencies.

Manulife IM quarterly discloses voting records aggregated across funds.4

Conflicts of interest

Manulife IM has an established infrastructure designed to identify conflicts of interest throughout all aspects of the business. Proxy voting proposals may raise conflicts between the interests of Manulife IM's clients and the interests of Manulife IM, its affiliates, or employees. Apparent conflicts are reviewed by the working group to

3We acknowledge SEC guidance on this issue from August 2019, which lists several nonexhaustive examples of possible voting arrangements between the client and investment advisor, including (i) an agreement with the client to exercise voting authority pursuant to specific parameters designed to serve the client's best interest; (ii) an agreement with the client to vote in favor of all proposals made by particular shareholder proponents; or (iii) an agreement with the client to vote in accordance with the voting recommendations of management of the issuer. All such arrangements could be subject to conditions depending on instruction from the client.

determine whether there is a conflict of interest and, if so, whether the conflict is material. Manulife IM shall consider any of the following circumstances a potential material conflict of interest:

•Manulife IM has a business relationship or potential relationship with the issuer;

•Manulife IM has a business relationship with the proponent of the proxy proposal; or

•Manulife IM members, employees, or consultants have a personal or other business relationship with managers of the business such as top-level executives, corporate directors, or director candidates.

In addressing any such potential material conflict, Manulife IM will seek to ensure proxy votes are cast in the advisory client's best interests and are not affected by Manulife IM's potential conflict. In the event a potential material conflict of interest exists, the working group or its designee will either (i) review the proxy voting decisions to ensure robust rationale, that the voting decision will protect or enhance shareholder value over the long term, and is in line with the best interest of the client; (ii) vote such proxy according to the specific recommendation of the proxy voting services provider; (iii) abstain; or (iv) request the client vote such proxy. The basis for the voting decision, including the process for the determination of the decision that is in the best interests of the client, is recorded.

Voting shares of Manulife Financial Corporation

Manulife Financial Corporation (MFC) is the publicly listed parent company of Manulife IM. Generally, legislation restricts the ability of a public company (and its subsidiaries) to hold shares in itself within its own accounts. Accordingly, the MFC share investment policy outlines the limited circumstances in which MFC or its subsidiaries may, or may not, invest or hold shares in MFC on behalf of MFC or its subsidiaries.5

The MFC share investment policy does not apply to investments made on behalf of unaffiliated third parties, which remain assets of the client. 6 Such investing may be restricted, however, by specific client guidelines, other Manulife policies, or other applicable laws.

Where Manulife IM is charged with voting MFC shares, we will execute votes in proportion with all other shareholders (i.e., proportional or echo vote). This is intended to neutralize the effect of our vote on the meeting outcome.

Policy responsibility and oversight

The working group oversees and monitors the policy and Manulife IM's proxy voting function. The working group is responsible for reviewing regular reports, potential conflicts of interest, vote changes, and nonroutine proxy voting items. The working group also oversees the third-party proxy voting service provider. The working group

will meet at least monthly and report to the Manulife IM public markets sustainable investing committee and, where requested, the Manulife IM operating committee.

Manulife IM's proxy operations team is responsible for the daily administration of the proxy voting process for all Manulife IM operations that have contracted with a third-party proxy voting services provider. Significant proxy voting issues identified by Manulife IM's proxy operations team are escalated to the chief compliance officer or its designee, and the working group.

The working group is responsible for the proper oversight of any service providers hired by Manulife IM to assist it in the proxy voting process. This oversight includes:

Annual due diligence: Manulife IM conducts an annual due diligence review of the proxy voting research service provider. This oversight includes an evaluation of the service provider's industry reputation, points of risk, compliance with laws and regulations, and technology infrastructure. Manulife IM also reviews the provider's capabilities to meet Manulife IM's requirements, including reporting competencies; the adequacy and quality of the proxy advisory firm's staffing and personnel; the quality and accuracy of sources of data and information; the strength of policies and procedures that enable it to make proxy voting recommendations based on current and accurate information; and the strength of policies and procedures to address conflicts of interest of the service provider related to its voting recommendations.

Regular Updates: Manulife also requests that the proxy voting research service provider deliver updates regarding any business changes that alter that firm's ability to provide independent proxy voting advice and services aligned with our policies.
