Attachment A – Code of Ethics

INTRODUCTION

This Code of Ethics (the “Code”) was originally adopted by Trillium Asset Management, LLC (“Trillium” or the “Company”) effective November 28, 2005, and has been updated to deal with changing circumstances. The most recent revision to this Code was on June 30, 2022. Trillium serves as the investment adviser to several client accounts, including the Trillium Funds, investment companies registered under the Investment Company Act of 1940 (the “Company Act”). This Code pertains to Trillium’s investment advisory and sub-advisory services. This Code establishes standards and procedures for the detection and prevention of activities by which persons having knowledge of the investments and investment intentions of a Client may abuse their fiduciary duties to the Client and addresses other types of conflict of interest situations. Definitions of underlined terms are included in Appendix A.

Nothing in this Code prohibits employees or Access Persons from reporting possible violations of federal law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal law or regulation.

1. WHO IS COVERED BY THIS CODE

This Code applies to all Access Persons (collectively the “Access Persons” and each an “Access Person” of Trillium (See Attachment A). “Access Person(s)” includes all Trillium full-time and part-time employees, manager trainees, interns, officers and directors.

Access Persons and their Immediate Family are required to strictly adhere to personal securities policies and procedures of this Code.

Directors who are not employees of Trillium and do not have access to confidential information regarding client securities transactions or recommendations are exempt from certain reporting provisions of this Code.

2. POLICY STATEMENT

The purpose of this Code of Ethics is to set forth certain key guidelines that have been adopted pursuant to Rule 204A-1 under the of the Investment Advisers Act of 1940 (the “Advisers Act”) and Rule 17j- 1 under the Company Act by Trillium as office policy for the guidance of all personnel and to specify the responsibility of all Access Persons of the Company to act in accordance with their fiduciary duty to Company clients and to comply with applicable federal and state laws and regulations, including, but not limited to, securities laws, governing their conduct. In particular, Access Persons should be aware of the requirements of the Advisers Act and Company Act. Careful adherence is essential to safeguard the interests of the Company and its clients. The Company expects that all Access Persons will conduct themselves in accordance with high ethical standards, which should be premised on the concepts of integrity, honesty and trust.

As noted, all Access Persons of the Company must conduct themselves in full compliance with all applicable federal and state laws and regulations concerning the securities industry. In particular, Access Persons should be familiar with those laws and regulations governing “insider trading” and

1

fiduciary duties. It is the responsibility of every Access Person to know these laws and regulations and to comply with them. Please consult Compliance for copies of any laws and regulations concerning the securities business or for any questions about the legality of any transaction.

Although our fiduciary duties require more than simply avoiding illegal and inappropriate behavior, at a minimum all Employees should be aware that, as a matter of policy and the terms of their employment with the Company, the following types of activities are strictly prohibited, in connection with the Purchase or sale, directly or indirectly, of a Security held or to be acquired by a client or prospective client or the Funds:

(1) Using any device, scheme or artifice to defraud a client or prospective client or the Funds

(2) Making any untrue statement of a material fact to a client or prospective client or the Funds or omitting to state a material fact necessary in order to make the statements made to a client or prospective client or the Funds, in light of the circumstances under which they are made, not misleading;

(3) Engaging in any act, practice, or course of business that operates or would operate as a fraud or deceit on a client or prospective client or the Funds;

(4) Engaging in any manipulative practice with respect to a client or prospective client or the Funds; and

(5) Causing the Company, acting as principal for its own account or for any account in which the Company or any person associated with the Company is a beneficial owner, to sell any security to or purchase any security from a client or the Funds in violation of any applicable law, rule or regulation of a governmental agency.

Trillium has always held itself and its Access Persons to the highest ethical standards. While this Code is only one manifestation of those standards, compliance with its provisions is essential. Failure to comply with this Code is a very serious matter and may result in disciplinary action being taken. Such action can include, among other things, private reprimand, disgorgement of profits, suspension or even termination of employment. Failure to submit personal security transactions report on a timely basis is a violation of this Code.

Access Persons must promptly report any suspected violations of the Code of Ethics to Compliance or an Officer. To the extent practicable, Trillium will protect the identity of an Access Person who reports a suspected violation. However, the Company remains responsible for satisfying the regulatory reporting, investigative and other obligations that may follow the reporting of a potential violation.

Retaliation against any Access Person who reports a violation of the Code of Ethics is strictly prohibited and will be cause for corrective action, up to and including dismissal.
