Each of the Registrant’s Executive 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 an Executive 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 Registrant’s Executive Officers, 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 Executive 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, Executive 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 Registrant’s Executive Officers is a n 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 Executive Officers are also officers or employees. As a result, this Code recognizes that the Registrant’s Executive 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 Executive 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 Executive Officers of their duties as officers of the Fund. Thus, if such participation is performed in confor mity 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 Executive 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 Registrant’s Executive Officers should keep in mind that these examples are not exhaustive. The overarching principle is that the personal interest of an Executive Officer should not be placed improperly before the interest of the Fund.

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 Executive 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 Executive 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:

►	service 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 Executive Officer’s employment, such as compensation
	or equity ownership.

III. Disclosure & Compliance

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

3 of 6 

	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 Executive Officer to promote compliance with the
	standards and restrictions imposed by applicable laws, rules and regulations.

IV. Reporting & Accountability

Each Executive Officer must:

►	upon adoption of the Code (or thereafter as applicable, upon becoming an Executive
	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 Executive 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
	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;

4 of 6 

►	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 Registrant’s Executive 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 Registrant’s Executive 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.
