Manning] Dear Shareholders, It has been said that change is the only constant in life. As investors have seen, that theme is still accurate today as we recently have experienced shifting economic cycles because of natural disasters and political instability around the globe. Markets worldwide have fluctuated in the past year as devastating hurricanes had a dramatic effect on the international economy, particularly on oil prices. We witnessed political unrest in the Middle East, highlighted by instability in Iraq, and in Africa, the usually stable Nigeria also experienced violence. As a result, energy prices have bounced up and down, with crude oil prices at one point topping a record $70 per barrel. Such cycles are not uncommon and in fact have almost become the norm in our everyday lives. What does all of this mean to you as an investor? In times like these, it helps to know that you're working with a seasoned investment professional who has experience to guide you through difficult times. At MFS(R), we believe our investment management team has the knowledge and confidence to navigate through difficult cycles and at the same time see through adversity to find investment opportunities for our clients and shareholders. Our investment management process, honed over 80 years, combines a unique concept of teamwork with our unwavering focus on the long term. We firmly believe that the best way to realize long-term financial goals - be it a college education, a comfortable retirement, or a secure family legacy - is to follow a three-pronged approach that focuses on longer time horizons. Allocate holdings across the major asset classes - including stocks, bonds, and cash. Diversify within each class to take advantage of different market segments and investing styles. Rebalance assets regularly to maintain a desired asset allocation. Of course, these strategies cannot guarantee a profit or protect against a loss. This long-term approach requires diligence and patience, two traits that in our experience are essential to capitalizing on the many opportunities the financial markets can offer - through both up and down economic cycles. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) July 17, 2006 The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

(d) Duration is a measure of how much a bond price is likely to fluctuate with general changes in interest rates, e.g., if rates rise 1.00%, a fund with a 5-year duration is likely to lose about 5.00% of its value. (i) For purposes of this graphical presentation, the bond component includes both accrued interest amounts and the equivalent exposure from any derivative holdings, if applicable. (m) The average maturity shown is calculated using the final stated maturity on the portfolio's holdings without taking into account any holdings which have been pre- refunded to an earlier date or which have a mandatory put date prior to the stated maturity. The average life shown takes into account these earlier dates. (r) Each security is assigned a rating from Moody's Investors Service. If not rated by Moody's, the rating will be that assigned by Standard & Poor's. Likewise, if not assigned a rating by Standard & Poor's, it will be based on the rating assigned by Fitch, Inc. For those portfolios that hold a security which is not rated by any of the three agencies, the security is considered Not Rated. Holdings in U.S. Treasuries and government agency mortgage-backed securities, if any, are included in a "AAA"-rating category. Percentages are based on the total market value of investments as of 5/31/06. Percentages are based on net assets as of 5/31/06, unless otherwise noted. The portfolio is actively managed, and current holdings may be different. PORTFOLIO MANAGER PROFILE Geoffrey L.

INDEX DEFINITION Lehman Brothers U.S. Government/Mortgage Bond Index - measures debt issued by the U.S. Government as well as mortgage-backed pass-through securities of Ginnie Mae (GNMA), Fannie Mae (FNMA), and Freddie Mac (FHLMC). It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY The trust's shares may trade at a discount to net asset value. Shareholders do not have the right to cause the trust to repurchase their shares at net asset value. When trust shares trade at a premium, buyers pay more than the asset value underlying trust shares, and shares purchased at a premium would receive less than the amount paid for them in the event of the trust's liquidation. As a result, the total returns that are calculated based on the net asset value and New York Stock Exchange prices can be different. The trust's monthly distributions may include a return of capital to shareholders. 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 have the effect of reducing the trust's assets and may increase the trust's expense ratio. From time to time the trust may receive proceeds from litigation settlements, without which performance would be lower. KEY RISK CONSIDERATIONS The portfolio's yield and share prices change daily based on the credit quality of its investments and changes in interest rates. In general, the value of debt securities will decline when interest rates rise and will increase when interest rates fall. Debt securities with longer maturity dates will be subject to greater price fluctuations than those with shorter maturities. Mortgage securities are subject to prepayment risk which can offer less potential for gains in a declining interest rate environment and greater potential for loss in a rising interest rate environment. Derivatives involve risks different from, and potentially greater than, those of the underlying indicator's in whose value the derivative is based. The value of the derivative can move in unexpected ways and result in unanticipated losses and increased volatility if the value of the underlying indicator(s) does not move in the direction or the extent anticipated. Interest payments on inflation adjusted debt instruments can be unpredictable and vary based on the level of inflation. The value of floating rate loans depends on the credit quality and adequacy of the collateral securing the loan. Enforcing rights against the collateral may be difficult or insufficient if the borrower of the floating rate loan defaults. Foreign investments can be more volatile than U.S. investments. Changes in currency exchange rates may affect the portfolio's net asset value, the value of dividends and interest earned and gains and losses realized on the sale of securities. Investing in emerging markets can involve risks in addition to those generally associated with investing in more developed foreign markets. When you sell your shares, they may be worth more or less than the amount you paid for them. These risks may increase share price volatility. In accordance with Section 23(c) of the Investment Company Act of 1940, the trust hereby gives notice that it may from time to time repurchase shares of the trust in the open market at the option of the Board of Trustees and on such terms as the Trustees shall determine. DIVIDEND REINVESTMENT AND CASH PURCHASE PLAN The trust offers a Dividend Reinvestment and Cash Purchase Plan that allows you to reinvest either all of the distributions paid by the trust or only the long-term capital gains. Purchases are made at the market price unless that price exceeds the net asset value (the shares are trading at a premium). If the shares are trading at a premium, purchases will be made at a discounted price of either the net asset value or 95% of the market price, whichever is greater. Twice each year you can also buy shares. Investments may be made in any amount over $100 in January and July on the 15th of the month or shortly thereafter. If your shares are in the name of a brokerage firm, bank, or other nominee, you can ask the firm or nominee to participate in the plan on your behalf. If the nominee does not offer the plan, you may wish to request that your shares be re-registered in your own name so that you can participate. There is no service charge to reinvest distributions, nor are there brokerage charges for shares issued directly by the trust. However, when shares are bought on the New York Stock Exchange or otherwise on the open market, each participant pays a pro rata share of the commissions. The automatic reinvestment of distributions does not relieve you of any income tax that may be payable (or required to be withheld) on the distributions. To enroll in or withdraw from the plan, or if you have any questions, call 1-800-637-2304 any business day from 8 a.m. to 8 p.m. Eastern time. Please have available the name of the trust and your account and Social Security numbers. For certain types of registrations, such as corporate accounts, instructions must be submitted in writing. Please call for additional details. When you withdraw from the plan, you can receive the value of the reinvested shares in one of two ways: a check for the value of the full and fractional shares, or a certificate for the full shares and a check for the fractional shares.

SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Government Markets Income Trust (the trust) is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as a closed-end management investment company. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The trust can invest in foreign securities, including securities of emerging market issuers. Investments in foreign securities are vulnerable to the effects of changes in the relative values of the local currency and the U.S. dollar and to the effects of changes in each country's legal, political, and economic environment. The markets of emerging markets countries are generally more volatile than the markets of developed countries with more mature economies. All of the risks of investing in foreign securities previously described are heightened when investing in emerging markets countries. INVESTMENT VALUATIONS - Debt instruments (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated or composite bid as reported by an independent pricing service. Values of debt instruments obtained from pricing services can utilize both dealer-supplied valuations and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics and other market data. Short-term instruments with a maturity at issuance of 397 days or less are generally valued at amortized cost, which approximates market value. Futures contracts are generally valued at last posted settlement price as reported by an independent pricing service on the market on which they are primarily traded. Futures contracts for which there were no trades that day for a particular position are generally valued at the closing bid quotation as reported by an independent pricing service on the market on which they are primarily traded. Forward foreign currency contracts are generally valued at the mean of bid and asked prices for the time period interpolated from rates reported by an independent pricing service for proximate time periods. Securities and other assets generally valued on the basis of information from an independent pricing service may also be valued at a broker-dealer bid quotation. The values of foreign securities and other assets and liabilities expressed in foreign currencies are converted to U.S. dollars using the mean of bid and asked prices for rates reported by an independent pricing service. The Board of Trustees has delegated primary responsibility for determining or causing to be determined the value of the trust's investments (including any fair valuation) to the adviser pursuant to valuation policies and procedures approved by the Board. If the adviser determines that reliable market quotations are not readily available, investments are valued at fair value as determined in good faith by the adviser in accordance with such procedures under the oversight of the Board of Trustees. Under the trust's valuation policies and procedures, market quotations are not considered to be readily available for many types of debt instruments. These investments are generally valued at fair value based on information from independent pricing services. The adviser may rely on independent pricing services or other information (such as the correlation with price movements of similar securities in the same or other markets; the type, cost and investment characteristics of the security; the business and financial condition of the issuer; and trading and other market data) to assist in determining whether to fair value and at what value to fair value an investment. The value of an investment for purposes of calculating the trust's net asset value can differ depending on the source and method used to determine value. When fair valuation is used, the value of investments used to determine the trust's net asset value may differ from quoted or published prices for the same investments. REPURCHASE AGREEMENTS - The trust may enter into repurchase agreements with institutions that the trust's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The trust requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the trust to obtain those securities in the event of a default under the repurchase agreement. The trust monitors, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the trust under each such repurchase agreement. The trust, along with other affiliated entities of Massachusetts Financial Services Company (MFS), may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. INFLATION-ADJUSTED DEBT SECURITIES - The trust invests in inflation-adjusted debt securities issued by the U.S. Treasury. The trust may also invest in inflation-adjusted debt securities issued by U.S. Government agencies and instrumentalities other than the U.S. Treasury and by other entities such as U.S. and foreign corporations and foreign governments. The principal value of these debt securities is adjusted by references to changes in the Consumer Price Index or another general price or wage index. These debt securities typically pay a fixed rate of interest, but this fixed rate is applied to the inflation-adjusted principal amount. The principal paid at maturity of the debt security is typically equal to the inflation-adjusted principal amount, or the security's original par value, whichever is greater. Other types of inflation-adjusted securities may use other methods to adjust for other measures of inflation. FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments, income, and expenses are converted into U.S. dollars based upon currency exchange rates prevailing on the respective dates of such transactions. Gains and losses attributable to foreign currency exchange rates on sales of securities are recorded for financial statement purposes as net realized gains and losses on investments. Gains and losses attributable to foreign exchange rate movements on income and expenses are recorded for financial statement purposes as foreign currency transaction gains and losses. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed. DERIVATIVE RISK - The trust may invest in derivatives for hedging or non- hedging purposes. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. When the trust uses derivatives as an investment to gain market exposure, or for hedging purposes, gains and losses from derivative instruments may be substantially greater than the derivative's original cost. Derivative instruments include forward foreign currency exchange contracts and futures contracts. FUTURES CONTRACTS - The trust may enter into futures contracts for the delayed delivery of securities or currency, or contracts based on financial indices at a fixed price on a future date. In entering such contracts, the trust is required to deposit with the broker either in cash or securities an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the trust each day, depending on the daily fluctuations in the value of the contract, and are recorded for financial statement purposes as unrealized gains or losses by the trust. Upon entering into such contracts, the trust bears the risk of interest or exchange rates or securities prices moving unexpectedly, in which case, the trust may not achieve the anticipated benefits of the futures contracts and may realize a loss. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS - The trust may enter into forward foreign currency exchange contracts for the purchase or sale of a specific foreign currency at a fixed price on a future date. Risks may arise upon entering into these contracts from the potential inability of counterparties to meet the terms of their contracts and from unanticipated movements in the value of the contract. The trust may enter into forward foreign currency exchange contracts for hedging purposes as well as for non-hedging purposes. For hedging purposes, the trust may enter into contracts to deliver or receive foreign currency it will receive from or require for its normal investment activities. The trust may also use contracts in a manner intended to protect foreign currency denominated securities from declines in value due to unfavorable exchange rate movements. For non-hedging purposes, the trust may enter into contracts with the intent of changing the relative exposure of the trust's portfolio of securities to different currencies to take advantage of anticipated changes. The forward foreign currency exchange contracts are adjusted by the daily exchange rate of the underlying currency and any gains or losses are recorded as unrealized until the contract settlement date. On contract settlement date, the gains or losses are recorded as realized gains or losses on foreign currency transactions. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. The trust may receive proceeds from litigation settlements involving its portfolio holdings. Any proceeds received are reflected in realized gain/loss in the Statement of Operations, or in unrealized gain/loss if the security is still held by the trust. FEES PAID INDIRECTLY - The trust's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the trust. This amount, for the six months ended May 31, 2006, is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The trust intends to continue to qualify as a regulated investment company, as defined under Subchapter M of the Internal Revenue Code, and to distribute all of its taxable income, including realized capital gains. Accordingly, no provision for federal income tax is required in the financial statements. Foreign taxes, if any, have been accrued by the trust in the accompanying financial statements. Distributions to shareholders are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Certain capital accounts in the financial statements are periodically adjusted for permanent differences in order to reflect their tax character. These adjustments have no impact on net assets or net asset value per share. Temporary differences which arise from recognizing certain items of income, expense, gain or loss in different periods for financial statement and tax purposes will reverse at some time in the future. Distributions in excess of net investment income or net realized gains are temporary overdistributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Book/tax differences primarily relate to amortization and accretion of debt securities, wash sale loss deferrals, straddle loss deferrals, foreign currency transactions, and derivative transactions. The tax character of distributions made during the current period will be determined at fiscal year end. The tax character of distributions declared to shareholders is as follows: NOVEMBER 30, 2005 NOVEMBER 30, 2004 Ordinary income (including any short-term capital gains) $16,936,571 $17,946,379 The federal tax cost and the tax basis components of distributable earnings were as follows: AS OF MAY 31, 2006 Cost of investments $382,079,279 ---------------------------------------------------------- Gross appreciation $1,508,879 Gross depreciation (17,427,396) ---------------------------------------------------------- Net unrealized appreciation (depreciation) $(15,918,517) AS OF NOVEMBER 30, 2005 Undistributed ordinary income 2,880,349 Capital loss carryforwards (21,219,412) Net unrealized appreciation (depreciation) (8,755,619) Other temporary differences (753,251) The aggregate cost above includes prior fiscal year end tax adjustments. As of November 30, 2005, the trust had available capital loss carryforwards to offset future realized gains. Such losses expire as follows: November 30, 2007 $(11,594,208) November 30, 2008 (5,988,179) November 30, 2012 (3,637,025) -------------------------------------------------- $(21,219,412) (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The trust has an investment advisory agreement with MFS to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at an annual rate of 0.32% of the trust's average daily net assets and 5.33% of gross investment income. MFS has agreed to temporarily reduce its management fee to the lesser of the contractual management fee as set forth above or 0.85% of the average daily net assets. The management fee, from net assets and gross investment income, incurred for the six months ended May 31, 2006 was equivalent to an annual effective rate of 0.62% of the trust's average daily net assets. TRANSFER AGENT - The trust pays a portion of transfer agent and dividend- disbursing costs to MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary of MFS. MFSC receives a fee from the trust, for its services as registrar and dividend-disbursing agent. The agreement provides that the trust will pay MFSC an account maintenance fee of no more than $9.00 and a dividend services fee of $0.75 per reinvestment. For the six months ended May 31, 2006, these fees amounted to $48,640. MFSC also receives payment from the trust for out-of-pocket expenses paid by MFSC on behalf of the trust. For the six months ended May 31, 2006, these costs amounted to $22,847. ADMINISTRATOR - MFS provides certain financial, legal, shareholder communications, compliance, and other administrative services to certain funds for which MFS acts as investment adviser. Under an administrative services agreement, the funds may partially reimburse MFS the costs incurred to provide these services, subject to review and approval by the Board of Trustees. Each fund is charged a fixed amount plus a fee based on calendar year average net assets. From July 1, 2005 through March 31, 2006, the trust's annual fixed amount was $10,000. Effective April 1, 2006, the trust's annual fixed amount is $17,500. The administrative services fee incurred for the six months ended May 31, 2006 was equivalent to an annual effective rate of 0.0152% of the trust's average daily net assets. TRUSTEES' AND OFFICERS' COMPENSATION - The trust pays compensation to Independent Trustees in the form of a retainer, attendance fees, and additional compensation to Board and Committee chairpersons. The trust does not pay compensation directly to Trustees or to officers of the trust who are also officers of the investment adviser, all of whom receive remuneration for their services to the trust from MFS. Certain officers and Trustees of the trust are officers or directors of MFS and MFSC. The trust has an unfunded, defined benefit plan for certain retired Independent Trustees which resulted in a pension expense of $7,396. The trust also has an unfunded retirement benefit deferral plan for certain Independent Trustees which resulted in an expense of $380. Both amounts are included in Independent trustees' compensation for the six months ended May 31, 2006. The deferred liability for retirement benefits payable to certain Trustees under both plans amounted to $170,593 at May 31, 2006, and is included in payable for independent trustees' compensation. DEFERRED TRUSTEE COMPENSATION - Under a Deferred Compensation Plan (the Plan) Independent Trustees previously were allowed to elect to defer receipt of all or a portion of their annual compensation. Trustees are no longer allowed to defer compensation under the Plan. Amounts previously deferred are treated as though equivalent dollar amounts had been invested in shares of the trust or other MFS funds selected by the Trustee. Deferred amounts represent an unsecured obligation of the trust until distributed in accordance with the Plan. Included in other assets and payable for independent trustees' compensation is $11,839 of Deferred Trustees' Compensation. OTHER - This trust and certain other MFS funds (the funds) have entered into a services agreement (the Agreement) which provides for payment of fees by the funds to Tarantino LLC in return for the provision of services of an Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the funds and the sole member of Tarantino LLC. The funds can terminate the Agreement with Tarantino LLC at any time under the terms of the Agreement. For the six months ended May 31, 2006, the fee paid to Tarantino LLC was $1,513.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Trustees and Shareholders of MFS Government Markets Income Trust: We have reviewed the accompanying statement of assets and liabilities of MFS Government Markets Income Trust (the "Trust"), including the portfolio of investments, as of May 31, 2006, and the related statement of operations, changes in net assets, and financial highlights for the six-month period ended May 31, 2006. These interim financial statements and financial highlights are the responsibility of the Trust's management. We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion. Based on our review, we are not aware of any material modifications that should be made to the accompanying interim financial statements and financial highlights referred to above for them to be in conformity with accounting principles generally accepted in the United States of America. We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the statement of changes in net assets for the year ended November 30, 2005, and financial highlights for each of the five years in the period ended November 30, 2005, and in our report dated January 23, 2006, we expressed an unqualified opinion on such statement of changes in net assets and financial highlights.

PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES. GENERAL. Information regarding the portfolio managers of the MFS Government Markets Income Trust (the "Fund") provided as of May 31, 2006 is set forth below. TITLE AND FIVE YEAR PORTFOLIO MANAGER PRIMARY ROLE SINCE HISTORY ----------------- ------------ ----- -------------------- Geoffrey L. Schechter Portfolio Manager April Senior Vice President of 2006 MFS; employed in the investment management area of MFS since 1993. COMPENSATION. Portfolio manager total cash compensation as of May 31, 2006 is a combination of base salary and performance bonus: o Base Salary - Base salary represents a relatively smaller percentage of portfolio manager total cash compensation (generally below 33%) than incentive compensation. o Performance Bonus - Generally, incentive compensation represents a majority of portfolio manager total cash compensation. The performance bonus is based on a combination of quantitative and qualitative factors, with more weight given to the former (generally over 60%) and less weight given to the latter. => The quantitative portion is based on pre-tax performance of all of the accounts managed by the portfolio manager (which includes the Fund and any other accounts managed by the portfolio manager) over a one-, three- and five-year period relative to the appropriate Lipper peer group universe and/or one or more benchmark indices with respect to each account. The primary weight is given to portfolio performance over a three-year time period with lesser consideration given to portfolio performance over one- and five-year periods (adjusted as appropriate if the portfolio manager has served for shorter periods). => The qualitative portion is based on the results of an annual internal peer review process (conducted by other portfolio managers, analysts and traders) and management's assessment of overall portfolio manager contributions to the investment process (distinct from portfolio performance). Portfolio managers also typically benefit from the opportunity to participate in the MFS Equity Plan. Equity interests in MFS or its parent company are awarded by management, on a discretionary basis, taking into account tenure at MFS, contribution to the investment process and other factors. Finally, portfolio managers are provided with a benefits package including a defined contribution plan, health coverage and other insurance, which are available to other employees of MFS on substantially similar terms. The percentage of compensation provided by these benefits depends upon the length of the individual's tenure at MFS and salary level as well as other factors. OWNERSHIP OF FUND SHARES. The following table shows the dollar range of equity securities of the Fund beneficially owned by the Fund's portfolio manager as of the Fund's semi-annual period ended May 31, 2006. The following dollar ranges apply: N. None A. $1 - $10,000 B. $10,001 - $50,000 C. $50,001 - $100,000 D. $100,001 - $500,000 E. $500,001 - $1,000,000 F. Over $1,000,000 NAME OF PORTFOLIO MANAGER DOLLAR RANGE OF EQUITY SECURITIES IN FUND ------------------------- ----------------------------------------- Geoffrey L. Schechter N OTHER ACCOUNTS. In addition to the Fund, the Fund's portfolio manager is responsible (either individually or jointly) for the day-to-day management of certain other accounts, the number and total assets of which as of the Fund's semi-annual period ended May 31, 2006 were as follows: REGISTERED INVESTMENT OTHER POOLED INVESTMENT COMPANIES VEHICLES OTHER ACCOUNTS -------------------- ------------------------ -------------- NUMBER OF NUMBER OF NUMBER OF NAME ACCOUNTS* TOTAL ASSETS* ACCOUNTS TOTAL ASSETS ACCOUNTS TOTAL ASSETS Geoffrey L. Schechter 10 $6 billion 1 $224 million 2 $198 million -------------- * Includes the Fund. Advisory fees are not based upon performance of any of the accounts identified in the table above. POTENTIAL CONFLICTS OF INTEREST. MFS seek to identify potential conflicts of interest resulting from a portfolio manager's management of both the Fund and other accounts and has adopted policies and procedures designed to address such potential conflicts. In certain instances there may be securities which are suitable for the Fund's portfolio as well as for accounts with similar investment objectives of the Adviser or subsidiary of the Adviser. Securities transactions for the Fund and other accounts with similar investment objectives are generally executed on the same day, or the next day. Nevertheless, it may develop that a particular security is bought or sold for only one client even though it might be held by, or bought or sold for, other clients. Likewise, a particular security may be bought for one or more clients when one or more other clients are selling that same security. When two or more clients are simultaneously engaged in the purchase or sale of the same security, the securities are allocated among clients in a manner believed by MFS to be fair and equitable to each. It is recognized that in some cases this system could have a detrimental effect on the price or volume of the security as far as the Fund is concerned. In most cases, however, MFS believes that the Fund's ability to participate in volume transactions will produce better executions for the Fund. MFS does not receive a performance fee for its management of the Fund. MFS and/or a portfolio manager may have an incentive to allocate favorable or limited opportunity investments or structure the timing of investments to favor accounts other than the Fund--for instance, those that pay a higher advisory fee and/or have a performance fee.
