Insights

Closed-End Funds Strategist

Aberdeen is signaling a credit-quality shift contingent on approvals.

The filing states Aberdeen intends to propose amending the Fund's fundamental investment policy to require an average portfolio credit quality that qualifies as investment grade, conditional upon shareholder approvals and completion of the announced reorganizations.

This would formally bind portfolio-credit quality under the Fund's fundamental policies; timing and final terms depend on shareholder votes and the adviser-transition mechanics disclosed in the joint prospectus/proxy materials.

Institutional Product Analyst

Reorganization and adviser change are the gating events for the policy amendment.

The announcement ties the proposed fundamental-policy change to the planned reorganizations of MFS funds into MMT and the adviser transition to Aberdeen, making the proposal conditional on those approvals.

Investors should note Aberdeen's scale: it reports $506B AUM and management of 27 closed-end funds totaling $25.6B as of March 31, 2026, which provides context for its closed-end fund experience.

closed-end fund financial

"Shares of closed-end funds are listed for trading on national securities exchanges"

A closed-end fund is a pool of money collected from many investors to buy a diversified mix of stocks, bonds, or other assets, and it is managed by professionals. Unlike some investment options, its shares are bought and sold on stock exchanges at prices determined by supply and demand, which can be above or below the fund's actual value. This structure allows investors to buy or sell shares easily, but the value may fluctuate based on market conditions.

dividend reinvestment plan financial

"Shareholders whose fund shares trade at a premium and who participate in the fund’s dividend reinvestment plan"

A dividend reinvestment plan lets shareholders automatically use cash dividends to buy more shares of the same company instead of receiving the money. It matters to investors because it turns regular payouts into a steady way to grow ownership and take advantage of compound returns—like having your savings automatically buy additional slices of a pie over time—while often reducing transaction costs and smoothing purchase timing.

abrdn Inc. Announces Intention to Propose a Future Policy Amendment for Aberdeen Multimarket
Income Trust, Subject to Shareholder Approval

(Philadelphia, May 11, 2026) – abrdn Inc. (“Aberdeen”), the proposed investment adviser to the MFS Multimarket Income Trust (“MMT” or the “Fund”), which is expected to be renamed the “Aberdeen Multimarket Income Fund” upon completion of the proposed transaction, announced today that, subject to applicable approvals, it intends to propose a future policy amendment to Fund shareholders for consideration and approval.

As previously announced by MFS on December 11, 2025, and as described in more detail in a joint prospectus/proxy statement mailed to shareholders of the Fund and the other participating funds and filed with the U.S. Securities and Exchange Commission (the “SEC”), it is proposed that, subject to shareholder approval, Aberdeen serve as investment adviser to MMT, together with the reorganization of certain other MFS closed-end funds; MFS Charter Income (“MCR”) and MFS Intermediate High Income (“CIF”), with and into MMT (collectively, the “Reorganizations”).

In additional proxy solicitation materials filed with the SEC on February 23, 2026, Aberdeen disclosed that, under normal market conditions, it intends to manage MMT to maintain an average investment grade credit quality portfolio.

Intended Future Proposed Fundamental Investment Policy

Following the completion of the Transaction, which remains subject to certain shareholder approvals, Aberdeen intends to submit a proposal to the Fund’s Board of Trustees and, if approved, to shareholders, to amend the Fund’s fundamental investment policies in order to require the Fund, under normal circumstances, to maintain an investment portfolio with an average credit quality qualifying as investment grade.

Any such proposal would be made only if shareholders of MCR approve the proposed reorganization and the adviser transition to Aberdeen is completed.

No Immediate Change to Investment Policies

Unless otherwise announced or until completion of the proposed Reorganizations and the investment adviser transition described in the aforementioned MMT joint prospectus/proxy statement, MMT will continue to operate in accordance with its current investment objectives, policies, and restrictions.

Circular 230 disclosure: To ensure compliance with requirements imposed by the U.S. Treasury, we inform you that any U.S. tax advice contained in this communication (including any attachments) is not intended or written to be used, and cannot be used, for the purpose of (i) avoiding penalties under the Internal Revenue Code or (ii) promoting, marketing or recommending to another party any transaction or matter addressed herein.

Important Information

Shares of closed-end funds are listed for trading on national securities exchanges and are bought and sold in the secondary market. The market price of a fund’s shares is determined by supply and demand and may be greater than (a “premium”) or less than (a “discount”) the fund’s net asset value (NAV). A fund’s investment return and principal value will fluctuate, and investors may receive more or less than their original investment upon the sale of shares. There is no assurance that a fund will achieve its investment objective. Past performance is not indicative of future results.

The trading price of a closed-end fund’s shares may be influenced by various factors, including market conditions, investor sentiment, and other external forces, and is not directly controlled by the fund, its Board of Directors, or its investment adviser. As a result, shares may trade at a premium to or discount from NAV at any given time. A premium to NAV may not be sustained, and a discount to NAV may increase or decrease over time. Investors should consider these risks when purchasing or selling closed-end fund shares.

Shareholders whose fund shares trade at a premium to NAV and who participate in the fund’s dividend reinvestment plan should be aware that distributions may be reinvested at prices above NAV, which may adversely affect investment results.
