The following disclosure related to Mellon is hereby added to the end of the "POTENTIAL CONFLICTS OF INTEREST-Conflicts of Interest Relating to the Sub-Adviserand Sub-Sub-Advisers"section of the SAI Part II:

Mellon

It is the policy of Mellon to make business decisions free from conflicting outside influences. Mellon's objective is to recognize potential conflicts of interest and work to eliminate or control and disclose such conflicts as they are identified. Mellon's business decisions are based on its duty to its clients, and not driven by any personal interest or gain. As an asset manager operating in several different jurisdictions with a diverse client and strategy base, conflicts of interest are inherent. Furthermore, as an indirect subsidiary of The Bank of New York Mellon Corporation ("BNY"), potential conflicts may also arise between Mellon and other BNY companies.

Mellon will take steps to provide reasonable assurance that no client or group of clients is advantaged at the expense of any other client. As such, Mellon has adopted a Code of Ethics and compliance policy manual to address such conflicts. These potential and inherent conflicts include but are not limited to:

Our compliance policies are designed to ensure that all client accounts are treated equitably over time. Additionally, Mellon has structured compensation of investment personnel to reasonably safeguard client accounts from being adversely impacted by any potential or related conflicts.

All material conflicts of interest are presented in greater detail within Part 2A of our Form ADV.

The following disclosure related to Mellon is hereby added to the end of the "PORTFOLIO MANAGER COMPENSATION" section of the SAI Part II:

The firm's rewards program is designed to be market-competitive and align our compensation with the goals of our clients.

Our incentive model is designed to compensate for quantitative and qualitative objectives achieved during the performance year.

Awards are paid in cash on an annual basis; however, some senior individuals may receive a portion of their annual incentive award in deferred vehicles. The following factors encompass our rewards program:

The following disclosure related to Mellon is hereby added to the end of "APPENDIX C - PROXY VOTING POLICIES" section of the SAI Part II:

Mellon Investments Corporation ("Mellon")

Mellon, through its Proxy Voting Committee (the "Proxy Voting Committee"), applies detailed, pre-determined,written proxy voting guidelines for specific types of proposals and matters commonly submitted to shareholders of U.S. and Japanese companies and those other companies established in non-U.S.jurisdictions that have significant operations occurring within the U.S. (the "Mellon Voting Guidelines"). For non-U.S.companies without significant U.S. operations, Mellon seeks to vote proxies through application of the ISS Global Voting Principles and Regional Policies/Principles (the "ISS Voting Guidelines" and, collectively with the Mellon Voting Guidelines, each as in effect from time-to-time,the "Voting Guidelines").

Mellon, in voting proxies, will seek to act solely in the best financial and economic interests of its clients, including the funds.

Mellon takes seriously its responsibility to vote proxies on behalf of its clients as a prudent fiduciary. In general, we employ proxy voting to:

Securities of Non-U.S.Companies. With regard to voting proxies with respect to shares of non-U.S.companies, Mellon weighs the cost of voting, and potential inability to sell, the shares against the benefit of voting the shares to determine whether or not to vote. However, corporate governance practices, disclosure requirements and voting operations vary significantly among the markets in which the funds may invest. In these markets, Mellon generally seeks to submit proxy votes in a manner consistent with the ISS Voting Guidelines, while taking into account the different legal and regulatory requirements. For example, proxy voting in certain countries requires "share blocking" pursuant to which a fund must deposit before the meeting date its holdings of securities with a designated depositary in order to vote proxies with respect to such securities. During this time, the shares cannot be sold until the meeting has taken place and the shares are returned to the fund's custodian bank. Mellon generally believes that the benefit of exercising the vote in these countries is outweighed by the cost of voting (i.e., the funds' portfolio managers not being able to sell the funds' shares of such securities while the shares are blocked). Therefore, if share blocking is required, Mellon typically elects not to vote the shares. Voting proxies of issuers in non-U.S.markets also raises administrative issues that may prevent voting such proxies. For example, meeting notices may be received with insufficient time to fully consider the proposal(s) or after the deadline for voting has passed. Other markets require the provision of local agents with a power of attorney before acting on the voting instructions. In some cases the power of attorney may be unavailable prior to the meeting date or rejected by the local agent on a technical basis. Additionally, the costs of voting in certain non-U.S.markets may be substantially higher than in the United States.

Securities Out on Loan. For securities that a fund has loaned to another party, any voting rights that accompany the loaned securities generally pass to the borrower of the securities, but the fund retains the right to recall a security and may then exercise the security's voting rights. In order to vote the proxies of securities out on loan, the securities must be recalled prior to the established record date. A fund may recall the loan to vote proxies if a material issue affecting the fund's investment is to be voted upon.

Material Conflicts of Interest. Mellon seeks to avoid material conflicts of interest between a fund and the fund's shareholders, on the one hand, and Mellon, or any affiliated person of the fund or Mellon, on the other, through several layers of controls, including its participation in the Proxy Voting Committee. The Proxy Voting Committee seeks to avoid material conflicts of interest through the establishment of the committee structure, the members of which are senior officers and investment professionals, and do not include individuals whose primary duties relate to sales, marketing or client services. The Proxy Committee applies detailed, pre-determinedproxy voting guidelines (the applicable Voting Guidelines) in an objective and consistent manner across client accounts, based on, as applicable, internal and external research and recommendations provided by third party proxy advisory services (including ISS and Glass Lewis, together the "Proxy Advisors") and without consideration of any client relationship factors. When proxies are voted in accordance with these pre-determinedVoting Guidelines, it is Mellon's view that these votes do not present the potential for a material conflict of interest and no additional safeguards are needed. In addition, Mellon engages a third party as an independent fiduciary to vote all proxies for securities of the Bank of New York Mellon Corporation ("BNY") and may engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law. These instances typically arise due to relationships between proxy issuers or companies and BNY, a BNY affiliate, a BNY executive, or a member of BNY's Board of Directors, but material conflicts of interests may also arise due to relationships involving Mellon and/or Mellon employees, officers and directors. When an independent fiduciary is engaged, the fiduciary either will vote the involved proxy, or provide Mellon with instructions as to how to vote such proxy. In the latter case, Mellon will vote the proxy in accordance with the independent fiduciary's determination. Other possible conflict resolutions may include: (1) voting in proportion to other shareholders ("mirror voting"); (2) erecting informational barriers around, or recusal from the vote decision making process by, the person or persons making voting decisions; and (3) voting in other ways that are consistent with our obligation to vote in our clients' best interest.

Operations of the Proxy Voting Committee. The Proxy Voting Committee also has engaged ISS as its proxy voting agent to administer the ministerial, nondiscretionary elements of proxy voting and reporting. In that role, ISS is required to follow the Voting Guidelines and apply them to the corresponding proxy proposals or matters on which a shareholder vote is sought. Accordingly, proxies that can be appropriately categorized and matched will be voted in accordance with the applicable Voting Guideline, or a proxy proposal will be referred to the Proxy Voting Committee if the Voting Guidelines so require, and generally for those proxy proposals or shareholder voting matters that are contested or similarly controversial and require a case-by-caseanalysis, as determined by the Committee in its discretion (e.g., proxy contests, potentially excessive executive compensation issues, or certain shareholder proposals). In addition, the Proxy Voting Committee has directed ISS to refer to it for discussion and vote all proxy proposals of those issuers: (1) where the percentage of their outstanding voting securities held in the aggregate in accounts managed Mellon is deemed significant or (2) that are at or above a certain specified market capitalization size (each, as determined by the Proxy Voting Committee in its discretion). For items referred to it, the Proxy Voting Committee may determine to accept or reject any recommendation based on the Voting Guidelines, research and analysis provided by its Proxy Advisors, or on any independent research and analysis obtained or generated by Mellon.

Mellon will furnish a copy of its Proxy Voting Policy and its Voting Guidelines upon request to each advisory client that has delegated voting authority. Our Voting Guidelines are also available publicly on our website at www.Mellon.com.
