LETTER FROM THE CHAIR AND CEO
Dear Shareholders:
Global markets have recently been buffeted by a series of crosscurrents, including rising inflation, tighter financial conditions, the continued spread of the coronavirus (particularly in Asia), and the evolving geopolitical landscape in the wake of Russia’s invasion of Ukraine. Consequently, at a time when global growth faces multiple headwinds, central banks have been presented with the challenge of reining in rising prices without tipping economies into recession. At its June meeting, the US Federal Reserve undertook a 0.75% rate hike, its largest since 1994. Additional larger-than-normal hikes are expected in coming meetings as the Fed seeks to move policy into restrictive territory by year-end to slow the economy and dampen inflation. Richly valued, rate-sensitive growth equities have been hit particularly hard by higher interest rates, and volatility in credit markets has picked up too.
There are, however, encouraging signs for the markets. The latest wave of COVID-19 cases appears to be receding in Asia, cases outside of Asia remain well below prior peaks, and fewer are seriously ill. Meanwhile, unemployment is low and there are signs that some global supply chain bottlenecks are beginning to ease, though lingering coronavirus restrictions in China and disruptions stemming from Russia’s invasion of Ukraine could hamper these advances. Additionally, easier Chinese monetary and regulatory policies and the record pace of corporate stock buybacks are supportive elements, albeit in an otherwise turbulent investment environment.
It is important to have a deep understanding of company fundamentals during times of market transition, and we have built our unique global research platform to do just that.
At MFS®, we put our clients’ assets to work responsibly by carefully navigating increasingly complex global capital markets. Our investment team is guided by a commitment to long-term fundamental investing. Our global investment platform — combining collective expertise, long-term discipline, and thoughtful risk management — seeks to uncover what we believe are the best, most durable investment ideas in markets around the world, enabling us to potentially create value for investors.
Respectfully,
Michael W. Roberge
Chair and Chief Executive Officer

Portfolio Composition - continued
(a) For all securities other than those specifically described below, ratings are assigned to underlying securities utilizing ratings from Moody’s, Fitch, and Standard & Poor’s rating agencies and applying the following hierarchy: If all three agencies provide a rating, the middle rating (after dropping the highest and lowest ratings) is assigned; if two of the three agencies rate a security, the lower of the two is assigned. If none of the 3 rating agencies above assign a rating, but the security is rated by DBRS Morningstar, then the DBRS Morningstar rating is assigned. If none of the 4 rating agencies listed above rate the security, but the security is rated by the Kroll Bond Rating Agency (KBRA), then the KBRA rating is assigned. Ratings are shown in the S&P and Fitch scale (e.g., AAA). Securities rated BBB or higher are considered investment grade. All ratings are subject to change. Not Rated includes fixed income securities and fixed income derivatives that have not been rated by any rating agency. The fund may or may not have held all of these instruments on this date. The fund is not rated by these agencies.
(b) Cash & Cash Equivalents (Less Liabilities) includes any cash, investments in money market funds, short-term securities, and other assets less liabilities. Liabilities include the value of the aggregate liquidation preference of the remarketable variable rate munifund term preferred shares (RVMTP shares) issued by the fund. Cash & Cash Equivalents (Less Liabilities) is negative due to the aggregate liquidation value of RVMTP shares. Please see the Statement of Assets and Liabilities for additional information related to the fund’s cash position and other assets and liabilities. Please see Note 8 in the Notes to Financial Statements for more information on the RVMTP shares issued by the fund.
(d) Duration is a measure of how much a bond’s price is likely to fluctuate with general changes in interest rates, e.g., if rates rise 1.00%, a bond with a 5-year duration is likely to lose about 5.00% of its value due to the interest rate move. This calculation is based on net assets applicable to common shares as of May 31, 2022.
(i) For purposes of this presentation, the components include the value of securities, and reflect the impact of the equivalent exposure of derivative positions, if any. These amounts may be negative from time to time. Equivalent exposure is a calculated amount that translates the derivative position into a reasonable approximation of the amount of the underlying asset that the portfolio would have to hold at a given point in time to have the same price sensitivity that results from the portfolio’s ownership of the derivative contract. When dealing with derivatives, equivalent exposure is a more representative measure of the potential impact of a position on portfolio performance than value. The bond component will include any accrued interest amounts.
(m) In determining each instrument’s effective maturity for purposes of calculating the fund’s dollar-weighted average effective maturity, MFS uses the instrument’s stated maturity or, if applicable, an earlier date on which MFS believes it is probable that a maturity-shortening device (such as a put, pre-refunding or prepayment) will cause the instrument to be repaid. Such an earlier date can be substantially shorter than the instrument’s stated maturity. This calculation is based on gross assets, which consists of net assets applicable to common shares plus the value of preferred shares, as of May 31, 2022.
(o) Less than 0.1%.
Other includes equivalent exposure from currency derivatives and/or any offsets to derivative positions and/or the leverage created through the issuance of self-deposited inverse floaters and may be negative.
Percentages are based on net assets applicable to common shares as of May 31, 2022.
The portfolio is actively managed and current holdings may be different.

Portfolio Managers' Profiles
Portfolio Manager Primary Role Since Title and Five Year History
Michael Dawson Portfolio Manager 2007 Investment Officer of MFS; employed in the investment management area of MFS since 1998.
Jason Kosty Portfolio Manager March 2022 Investment Officer of MFS; employed in the investment management area of MFS since 2014.
Geoffrey Schechter Portfolio Manager 2007 Investment Officer of MFS; employed in the investment management area of MFS since 1993.

Other Notes
The fund’s shares may trade at a discount or premium to net asset value. When fund shares trade at a premium, buyers pay more than the net asset value underlying fund shares, and shares purchased at a premium would receive less than the amount paid for them in the event of the fund’s concurrent liquidation.
The fund’s monthly distributions may include a return of capital to shareholders to the extent that distributions are in excess of the fund’s net investment income and net capital gains, determined in accordance with federal income tax regulations. Distributions that are treated for federal income tax purposes as a return of capital will reduce each shareholder’s basis in his or her shares and, to the extent the return of capital exceeds such basis, will be treated as gain to the shareholder from a sale of shares. Returns of shareholder capital may have the effect of reducing the fund’s assets and increasing the fund’s expense ratio.
In accordance with Section 23(c) of the Investment Company Act of 1940, the fund hereby gives notice that it may from time to time repurchase shares of the fund in the open market at the option of the Board of Trustees and on such terms as the Trustees shall determine.
