Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- MFS Original Research THE MFS(R) DIFFERENCE For 80 years MFS has been offering investors clear paths to pursuing specific investment objectives. Today, millions of individuals and thousands of institutions all over the world look to MFS to manage their assets with insight and care. Our success, we believe, has to do with the fact that we see investors as people with plans, not just dollars to invest. When you invest with MFS, you invest with a company dedicated to helping you realize your long-term financial goals. INVESTORS CHOOSE MFS FOR OUR o global asset management expertise across all asset classes o time-tested money management process for pursuing consistent results o full spectrum of investment products backed by MFS Original Research(R) o resources and services that match real-life needs TURNING INFORMATION INTO OPPORTUNITY Sound investments begin with sound information. MFS has been doing its own research and analyzing findings in-house for decades. The process we use to uncover opportunity is called MFS Original Research(R). MFS ORIGINAL RESEARCH INVOLVES: o meeting with the management of 3,000 companies each year to assess their business plans and the managers' ability to execute those plans o making onsite visits to more than 2,000 companies annually to gain first-hand knowledge of their operations and products o analyzing financial statements and balance sheets o talking extensively with companies' customers and competitors o developing our own proprietary estimates of companies' earnings - -------------------------------------------------------------------------------- MANAGEMENT REVIEW - -------------------------------------------------------------------------------- MARKET ENVIRONMENT Over the six-month period ended February 29, 2004, bond prices rallied dramatically as rates fell. On average, municipal issues modestly outperformed U.S. Treasury issues of similar maturities. (Principal and interest of U.S. Treasury securities, however, are guaranteed by the U.S. government if held to maturity.) The key driver of falling rates, in our view, was a turnaround in investor expectations. In September of 2003, we felt the market in general expected that continued consumer demand would lead to increased manufacturing output, increased capital spending by corporations, and increased hiring. Along with many investors, we believed those trends would potentially put upward pressure on inflation and lead the Federal Reserve Board to begin raising interest rates by the spring of 2004. However, while consumers did continue to spend over the period, corporate spending on plants and equipment rose only modestly, and job creation was disappointingly weak. This set of circumstances, in our opinion, confirmed the view of the Federal Reserve Board, stated late in the period, that it would leave short-term rates unchanged for the foreseeable future, in part due to excess capacity in the system. These factors, we believe, increased the perceived risk that the economic recovery could falter and, therefore, caused investors to push up long-term bond prices - because high-quality bonds are seen as a refuge in times of economic concern. As of period-end on February 29, 2004 we believe the consensus view among economists is that the Fed would not increase rates until December of 2004 at the earliest. PORTFOLIO CONCENTRATION AS OF 2/29/04 QUALITY RATINGS AAA 64.5% AA 12.4% A 13.5% BBB 8.7% BB 0.05% Not rated 0.8% Other 0.05% The portfolio is actively managed, and current holdings may be different. PERFORMANCE RELATIVE TO OUR LIPPER PEER GROUP Over the period, the fund underperformed the average fund in its Lipper peer group, general municipal debt funds. The key driver of that underperformance was a relatively short average duration, as compared with our Lipper peers. (Duration is a measure of a fund's sensitivity to changes in interest rates.) Historically, our investment philosophy has been to try to be duration-neutral relative to our peers. However, over the period we did manage the portfolio to be relatively short on duration - i.e., less sensitive to interest rate changes - because we felt there was a greater probability that rates would rise, which would have been negative for bond prices. When the opposite occurred and rates fell, our shorter duration caused us to benefit somewhat less than our peers from the rally in bond prices. Not owning lower-quality bonds was also negative for performance relative to our peers. The fund is positioned as a high-quality fund and our prospectus does not permit the purchase of non-investment-grade issues (those rated below "BBB" by the major rating agencies) or the purchase of unrated issues, unless our analysts deem those unrated bonds to be investment-grade. Our peer group, however, includes funds that do purchase lower-rated bonds. As corporate profits generally improved over the period and U.S. firms in general continued to strengthen their balance sheets, lower-rated corporate-backed municipal issues outperformed higher-grade issues. In that environment, our inability to purchase lower-rated issues hurt performance relative to our peers. Security selection, however, benefited performance against our peers. In the health care sector, our analysts' selections of hospital bonds were particularly strong. Lease-backed bonds were another area of relative outperformance compared with our peers. These portfolio holdings were largely state-appropriated debt issues, which are paid through annual state appropriations. PERFORMANCE RELATIVE TO THE LEHMAN INDEX Over the period, the fund also underperformed its benchmark, the Lehman Brothers Municipal Bond Index (the Lehman Index). Here again, our short duration posture was a key detractor from relative results, as explained above. A relative overweighting in housing bonds also dampened results. Over the longer term, we like this sector because it has historically delivered lower volatility of returns and higher levels of income than some sectors with similar risk levels. However, falling interest rates over the period increased the prepayment risks associated with housing bonds and therefore muted their performance. (Prepayment risk is the risk that homeowners will prepay their mortgages to refinance at a lower rate, forcing housing bond holders to reinvest at lower prevailing rates.) A relative underweighting in tobacco bonds also modestly held back performance. Tobacco bonds are state bonds backed by payments under the Master Settlement Agreement (MSA) between the states and the major tobacco companies, in which the states agreed to drop their lawsuits against the firms in return for a series of payments. An underweighting in those bonds had helped performance during the preceding one-year period that ended August 31, 2003, as other lawsuits raised concerns about the tobacco firms' ability to continue MSA payments. During the six-month period ended February 29, 2004, however, those litigation concerns appeared to subside, tobacco bonds rallied, and our underweighting proved somewhat detrimental to performance. Positioning on the yield curve, however, helped our relative performance against the Lehman Index. When interest rates fall, as they did over the period, bonds with longer maturities receive a greater benefit from the rate move than shorter-maturity bonds. In that environment, performance benefited from our overweighting relative to the Lehman Index in longer-maturity bonds and our underweighting in bonds with maturities below five years.

INDEX DEFINITION THE LEHMAN BROTHERS MUNICIPAL BOND INDEX - is a broad measure of the municipal bond market. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class A results, including sales charge, reflects the deduction of the maximum 4.75% sales charge. Class B results, including sales charge, reflects the deduction of the applicable contingent deferred sales charge (CDSC), which declines over six years from 4% to 0%. Performance for share classes offered after class A shares includes the performance of the fund's class A shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details. KEY RISK CONSIDERATIONS A small portion of income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax. Income earned on bonds issued by states of which you are not a resident, or their political subdivisions, may be subject to taxation by the state in which you reside. Investments in high yield or lower-rated securities may provide greater returns but are subject to greater-than-average risk. These risks may increase share price volatility. Please see the prospectus for further information regarding these and other risk considerations. This report is prepared for the general information of shareholders. It is authorized for distribution to prospective investors only when preceded or accompanied by a current prospectus. - -------------------------------------------------------------------------------------------- PORTFOLIO OF INVESTMENTS (unaudited) - 2/29/04 - -------------------------------------------------------------------------------------------- The Portfolio of Investments is a complete list of all securities owned by your fund.

See notes to financial statements. - -------------------------------------------------------------------------------- NOTES TO FINANCIAL STATEMENTS (unaudited) - -------------------------------------------------------------------------------- (1) BUSINESS AND ORGANIZATION MFS Municipal Bond Fund (the fund) is a diversified series of MFS Series Trust IV (the trust). The trust is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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. Municipal securities backed by current or anticipated revenues from a specific project or specific assets can be negatively affected by the discontinuance of the taxation supporting the projects or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service determines an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could become taxable and the security could decline in value. INVESTMENT VALUATIONS - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Bonds and other fixed income securities (other than short-term obligations) in the fund's portfolio are valued at an evaluated bid price as reported by an independent pricing service, or to the extent a valuation is not reported by a pricing service, such securities are valued on the basis of quotes from brokers and dealers. Prices obtained from pricing services utilize both dealer-supplied valuations and electronic data processing techniques which take into account appropriate 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 without exclusive reliance upon quoted prices or exchange or over-the-counter prices, since such valuations are believed to reflect more accurately the fair value of such securities. Bonds and other fixed income securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. SWAP AGREEMENTS - The fund may enter into swap agreements. A swap is an exchange of cash payments between the fund and another party, which is based on a specific financial index. Cash payments are exchanged at specified intervals and the expected income or expense is recorded on the accrual basis. The value of the swap is adjusted daily and the change in value is recorded as unrealized appreciation or depreciation. Risks may arise upon entering into these agreements from the potential inability of counterparties to meet the terms of their contract and from unanticipated changes in the value of the financial index on which the swap agreement is based. The fund uses swaps for both hedging and non-hedging purposes. For hedging purposes, the fund may use swaps to reduce its exposure to interest rate fluctuations. For non-hedging purposes, the fund may use swaps to take a position on anticipated changes in the underlying financial index. RATE LOCK SWAPS - The fund may enter into rate lock swaps, which are used to reduce the interest rate risk of the portfolio. A rate lock swap is a payment or receipt of cash on a specified future date, calculated as the difference between the strike rate and a specific index yield on that date. The payment received or made at the end of the measurement period is recorded as a realized gain or loss in the Statement of Operations. The value of the swap is adjusted daily and the change in value is recorded as unrealized appreciation or depreciation. 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 accounting principles generally accepted in the United States of America. All premium and original issue discount is amortized or accreted for tax reporting purposes as required by federal income tax regulations. Some securities may be purchased on a "when-issued" or "forward delivery" basis, which means that the securities will be delivered to the fund at a future date, usually beyond customary settlement time. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. This amount, for the six months ended February 29, 2004, is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund's policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net tax- exempt and taxable net income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions paid by the fund from net interest received on tax-exempt municipal bonds are not includable by shareholders as gross income for federal income tax purposes because the fund intends to meet certain requirements of the Code applicable to regulated investment companies, which will enable the fund to pay exempt-interest dividends. The portion of such interest, if any, earned on private activity bonds issued after August 7, 1986 may be considered a tax-preference item to shareholders. Distributions to shareholders are recorded on the ex-dividend date. The fund distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in capital. Differences in the recognition or classification of income between the financial statements and tax earnings and profits, which result in temporary over-distributions for financial statement purposes, are classified as distributions in excess of net investment income or net realized gains. Common types of book and tax differences that could occur include differences in accounting for derivatives and amortization and accretion on debt securities. The tax character of distributions declared for the years ended August 31, 2003 and August 31, 2002 was as follows: 8/31/03 8/31/02 Distributions declared from tax exempt income $67,795,702 $67,782,333 - --------------------------------------------------------------------- As of August 31, 2003, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed tax-exempt income $5,225,211 - -------------------------------------------------------------------------------- Capital loss carryforward (9,231,853) - -------------------------------------------------------------------------------- Unrealized appreciation 107,491,691 - -------------------------------------------------------------------------------- Post-October capital loss deferral (2,779,802) - -------------------------------------------------------------------------------- Other temporary differences (5,770,223) - -------------------------------------------------------------------------------- Post-October capital loss deferrals represent losses realized during the current fiscal year, but recognized for tax purposes in the next fiscal year. For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on August 31, 2009, ($8,819,272) and August 31, 2011 ($412,581). MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on the value of settled shares outstanding of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class B shares will convert to Class A shares approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at the following annual rates: First $1.3 billion of average net assets 0.40% - -------------------------------------------------------------------------------- Average net assets in excess of $1.3 billion 0.37% - -------------------------------------------------------------------------------- Average net assets in excess of $2 billion 0.35% - -------------------------------------------------------------------------------- Management fees incurred for the six months ended February 29, 2004 were 0.40% of average daily net assets on an annualized basis. As part of the settlement agreement with the New York Attorney General concerning market timing and related matters, MFS has agreed to reduce the fund's management fee to 0.30% of average daily net assets for the period March 1, 2004 through February 28, 2009. During this time period, the Board of Trustees will continue to review the appropriateness of all advisory fees in accordance with their oversight responsibilities. After February 28, 2009 the management fee will be determined in accordance with then existing review policies approved by the Board of Trustees overseeing the fund. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded, defined benefit plan for retired Independent Trustees. Included in Trustees' compensation is a pension expense of $3,281 for retired Independent Trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund's average daily net assets: First $2 billion 0.0175% - -------------------------------------------------------------------------------- Next $2.5 billion 0.0130% - -------------------------------------------------------------------------------- Next $2.5 billion 0.0005% - -------------------------------------------------------------------------------- In excess of $7 billion 0.0000% - -------------------------------------------------------------------------------- DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received $91,432 for the six months ended February 29, 2004, as its portion of the sales charge on sales of Class A shares of the fund. The Trustees have adopted a distribution plan for Class B shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. These fees are calculated based on each class' average daily net assets.

Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $55,463 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors.

Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the bank's base rate plus 0.50%. In addition, a commitment fee, based on the average daily unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004, was $4,424. The fund had no borrowings during the period. (7) FINANCIAL INSTRUMENTS The fund trades financial instruments with off-balance-sheet risk in the normal course of its investing activities in order to manage exposure to market risks such as interest rates. These financial instruments include swap agreements. The notional or contractual amounts of these instruments represent the investment the fund has in particular classes of financial instruments and does not necessarily represent the amounts potentially subject to risk. The measurement of the risks associated with these instruments is meaningful only when all related and offsetting transactions are considered.

Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust IV, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

Manning] Dear Shareholders, As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. - ------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - ------------------------------------------------------------------------------- THE MFS(R) DIFFERENCE For 80 years MFS has been offering investors clear paths to pursuing specific investment objectives.

INVESTORS CHOOSE MFS FOR OUR o global asset management expertise across all asset classes o time-tested money management process for pursuing consistent results o full spectrum of investment products backed by MFS Original Research(R) o resources and services that match real-life needs TURNING INFORMATION INTO OPPORTUNITY Sound investments begin with sound information. MFS has been doing its own research and analyzing findings in-house for decades. The process we use to uncover opportunity is called MFS Original Research(R).

The release of increasingly positive economic numbers as the period progressed, particularly with regard to corporate earnings and GDP (gross domestic product) growth, helped drive the equity rally. Another driver of the equity rally, in our view, was the U.S. Federal Reserve Board's decision to leave interest rates at a four-decade low throughout the period. While energy prices rose late in the period, core inflation -- excluding volatile food and energy prices -- remained low relative to historical averages. For the period, the portfolio underperformed its benchmark, the Russell Midcap Growth Index, but outperformed its peers, as measured by the average mid-cap growth fund tracked by Lipper Inc. DETRACTORS FROM PERFORMANCE On a sector basis, leisure, business services and health care were the strongest detractors from relative performance. Among our leisure investments, media holdings such as broadcast and programming services provider Westwood One detracted from performance because of a slower-than-expected recovery in advertising. As of period-end, the stock remained in the portfolio based on our expectation of increasing advertising spending in 2004. In the business services area, online recruitment advertiser Monster Worldwide weighed on results, reflecting concerns about increasing competition, management's decision not to renew a large contract, and the weak recovery in the job market. - ----------------------------------------------- TOP 5 STOCK HOLDINGS AS OF 2/29/04 NTL, INC. 2.9% Broadband and cable services provider - ----------------------------------------------- CYTYC CORPORATION 2.5% Medical diagnostics technology firm - ----------------------------------------------- MILLIPORE CORP. 2.3% Life sciences company - ----------------------------------------------- CAREER EDUCATION CORPORATION 2.3% Adult education and training services provider - ----------------------------------------------- MEDICIS PHARMACEUTICAL CORPORATION 1.8% Pharmaceutical manufacturer - ----------------------------------------------- The portfolio is actively managed, and current holdings may be different. - ----------------------------------------------- Among our health care holdings, shares of acute care provider Tenet Healthcare declined amid weak admissions and pricing trends and ongoing concerns about the investigation of past billing practices. Relative to our benchmark, not owning medical and reconstructive devices firm Zimmer Holdings also held back performance, as the firm's shares rose during the period. Individual stocks in other areas that held back relative performance included jetBlue Airways, whose shares fell because of increasing competition in the low-cost airline market and rising fuel prices. In the technology sector, we held storage solution provider VERITAS Software, whose shares posted a negative return for the period. Our holding in clothing retailer Talbots also held back results. The company's shares declined after the firm posted relatively weak profits during the 2003 fall and holiday shopping seasons. Talbots was sold out of the portfolio by period-end. Although it averaged less than 4% of fund assets over the period, the portfolio's cash position was also a detractor from relative performance. In a period when equity markets rose sharply, cash held back performance against our benchmark, the Russell Midcap Growth Index, which has no cash position. CONTRIBUTORS TO PERFORMANCE Relative to our benchmark, the portfolio fared most favorably in the technology, industrial goods and services, and consumer staples sectors. Stockpicking in these three sectors had the largest positive effect on returns during the period. On a sector basis, technology was the largest contributor to performance relative to the benchmark. Technology holdings that rose sharply included communications semiconductor company PMC-Sierra and programmable logic design company Xilinx. Both firms benefited from an upswing in semiconductor demand and market share gains for their well-positioned products. Also, not owning semiconductor equipment maker KLA-Tencor benefited relative performance as the firm's stock declined during the period. While the industrial goods and services sector did not hold any of the portfolio's top contributors, several of our stock holdings in this area made material contributions to overall relative performance, including plumbing and HVAC equipment maker American Standard Cos. and industrial automation manufacturer Rockwell Automation. Also, not owning Jacobs Engineering helped relative performance, as the construction firm's shares posted negative returns for the period. In consumer staples, manufacturer and marketer of ice cream, frozen dessert, and frozen novelty products CoolBrands International was among the portfolio's top relative performers for the period. Individual stock holdings in other sectors that helped performance included NTL, which was the portfolio's best performer on a relative basis, Investors Financial Services, MedImmune, Royal Caribbean Cruises, and Invitrogen. In the leisure sector, shares of NTL, the largest broadband services and cable operator in Great Britain, posted strong returns after the company emerged from bankruptcy and continued to strengthen its balance sheet and improve cash flow growth. Our position in Royal Caribbean Cruises also posted strong results for the period, as the firm experienced improving booking trends. In financial services, our position in Investors Financial Services contributed to performance. The administration services provider's shares rose on a stronger capital markets environment, healthy earnings growth, and new business wins. In health care, medical equipment firm Invitrogen, which sells life science tools used in research and drug manufacturing, benefited from an industry recovery and from improved product offerings and efficiency gains under a new CEO. Our relative underweighting in biotech company MedImmune also helped portfolio performance, as its shares declined during the period. Respectfully, /s/ Eric B. Fischman /s/ David E.

INDEX DEFINITION THE RUSSELL MIDCAP GROWTH INDEX - measures the performance of U.S. mid-cap growth stocks. It is not possible to invest directly in an index. NOTES TO PERFORMANCE SUMMARY Class A and 529A results, including sales charge, reflect the deduction of the maximum 5.75% sales charge. Class B and 529B results, including sales charge, reflect the deduction of the applicable contingent deferred sales charge (CDSC), which declines over six years from 4% to 0%. Class C and 529C results, including sales charge, redeemed within one year from the end of the calendar month of purchase, reflect the deduction of the 1% CDSC. Class I shares have no sales charges and are available only to certain investors. Class R1 and R2 shares have no sales charges and are available only to certain retirement plans. Class 529A, 529B, and 529C shares are only available in conjunction with qualified tuition programs, such as the MFS 529 Savings Plan. Performance for share classes offered after class A shares includes the performance of the fund's class A shares for periods prior to their offering. Blended class performance has been adjusted to take into account differences in sales loads, if any, applicable to these share classes, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Compared to performance these share classes would have experienced had they been offered for the entire period, the use of blended performance generally results in higher performance for share classes with higher operating expenses than the initial share class, and lower performance for share classes with lower operating expenses than the initial share class. Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown. Without such subsidies and waivers the fund's performance results would be less favorable. Please see the prospectus and financial statements for complete details. KEY RISK CONSIDERATIONS Investing in foreign and/or emerging markets securities involves risks relating to interest rates, currency exchange rates, economic, and political conditions. These risks may increase share price volatility. Please see the prospectus for further information regarding these and other risk considerations.

See notes to financial statements. - ------------------------------------------------------------------------------ NOTES TO FINANCIAL STATEMENTS (unaudited) - ------------------------------------------------------------------------------ (1) BUSINESS AND ORGANIZATION MFS Mid Cap Growth Fund (the fund) is a diversified series of MFS Series Trust IV (the trust). The trust is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 fund can invest in foreign securities. 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. INVESTMENT VALUATIONS - The fund uses independent pricing services approved by the Board of Trustees wherever possible to value its portfolio securities. Portfolio securities are valued at current market prices where current market prices are readily available, or the fund may fair value portfolio securities under the direction of the Board of Trustees when a determination is made that current market prices are not readily available. Equity securities in the fund's portfolio for which market quotations are available are valued at the last sale or official closing price as reported by an independent pricing service on the primary market or exchange on which they are primarily traded, or at the last quoted bid price for securities in which there were no sales during the day. Equity securities traded over the counter are valued at the last sales price traded each day as reported by an independent pricing service, or to the extent there are no sales reported, such securities are valued on the basis of quotations obtained from brokers and dealers. Equity securities for which it is determined that current market prices are not readily available will be fair valued under the direction of the Board of Trustees. The fund may also fair value foreign equity securities in cases where closing market prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that foreign markets close (where the security is principally traded) and the time that the fund calculates its net asset value (generally, the close of the NYSE) that may impact the value of securities traded in these foreign markets. In these cases, the fund may utilize information from an external vendor or other sources to adjust closing market prices of foreign equity securities to reflect what it believes to be the fair value of the securities as of the fund's valuation time. Because the frequency of significant events is not predictable, fair valuation of foreign equity securities may occur on a frequent basis. Short-term obligations with a remaining maturity in excess of 60 days will be valued upon dealer-supplied valuations. All other short-term obligations in the fund's portfolio are valued at amortized cost, which constitutes market value as determined by the Board of Trustees. Money market mutual funds are valued at net asset value. Investment valuations, other assets, and liabilities initially expressed in foreign currencies are converted each business day into U.S. dollars based upon current exchange rates. REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with institutions that the fund's investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. The fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. The fund 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 fund under each such repurchase agreement. The fund, 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. 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. SECURITY LOANS - State Street Bank and Trust Company ("State Street") and J.P. Morgan Chase and Co. ("Chase"), as lending agents, may loan the securities of the fund to certain qualified institutions (the "Borrowers") approved by the fund. The loans are collateralized at all times by cash and/or U.S. Treasury securities in an amount at least equal to the market value of the securities loaned. State Street and Chase provide the fund with indemnification against Borrower default. The fund bears the risk of loss with respect to the investment of cash collateral. On loans collateralized by cash, the cash collateral is invested in a money market fund or short-term securities. A portion of the income generated upon investment of the collateral is remitted to the Borrowers, and the remainder is allocated between the fund and the lending agents. On loans collateralized by U.S. Treasury securities, a fee is received from the Borrower, and is allocated between the fund and the lending agents. The dividend and interest income earned on the securities loaned is accounted for in the same manner as other dividend and interest income. 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 accounting principles generally accepted in the United States of America. All discount is accreted for tax reporting purposes as required by federal income tax regulations. Dividends received in cash are recorded on the ex-dividend date. Dividend and interest payments received in additional securities are recorded on the ex-dividend or ex-interest date in an amount equal to the value of the security on such date. FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. During the six months ended February 29, 2004, the fund's custodian fees were reduced by $7,296 under this arrangement. The fund has entered into a commission recapture agreement under which certain brokers will credit the fund a portion of the commissions generated, to offset certain expenses of the fund. For the six months ended February 29, 2004, the fund's miscellaneous expenses were reduced by $64,994 under this agreement. These amounts are shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The fund's policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The fund distinguishes between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in capital. Differences in the recognition or classification of income between the financial statements and tax earnings and profits, which result in temporary over-distributions for financial statement purposes, are classified as distributions in excess of net investment income or net realized gains. Common types of book and tax differences that could occur include differences in accounting for currency transactions and passive foreign investment companies. The tax character of distributions declared for the years ended August 31, 2003 and August 31, 2002 was as follows: 8/31/03* 8/31/02 Distributions declared from - ------------------------------------------------------------------------------- Ordinary income $-- $29,844,255 - ------------------------------------------------------------------------------- Tax return of capital -- $1,957,586 - ------------------------------------------------------------------------------- Long-term capital gain -- 5,313 - ------------------------------------------------------------------------------- Total distributions declared $-- $31,807,154 - ------------------------------------------------------------------------------- * The fund made no distributions for the fiscal year ended August 31, 2003. As of August 31, 2003, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Capital loss carryforward $(1,858,981,945) - --------------------------------------------------------------------------- Unrealized appreciation 304,267,437 - --------------------------------------------------------------------------- Post-October capital loss deferral (27,202,174) - --------------------------------------------------------------------------- Other temporary differences (90,258) - --------------------------------------------------------------------------- Post-October capital loss deferrals represent losses realized during the current fiscal year, but recognized for tax purposes in the next fiscal year. For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on August 31, 2010, $(71,932,545) and August 31, 2011 $(1,787,049,400). MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple classes of shares, which differ in their respective distribution and service fees. All shareholders bear the common expenses of the fund based on daily net assets of each class, without distinction between share classes. Dividends are declared separately for each class. Differences in per share dividend rates are generally due to differences in separate class expenses. Class B and Class 529B shares will convert to Class A and Class 529A shares, respectively approximately eight years after purchase. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - The fund 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 0.75% of the fund's average daily net assets. The fund pays compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pays no compensation directly to its Trustees who are officers of the investment adviser, or to officers of the fund, all of whom receive remuneration for their services to the fund from MFS. Certain officers and Trustees of the fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an unfunded, defined benefit plan for retired Trustees and an unfunded retirement benefit deferral plan for current Trustees. Included in Trustees' compensation is a net increase of $7,607 as a result of the change in the fund's pension liability for current Trustees and a pension expense of $1,465 for retired Independent Trustees for the six months ended February 29, 2004. ADMINISTRATOR - The fund has an administrative services agreement with MFS to provide the fund with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, the fund pays MFS an administrative fee up to the following annual percentage rates of the fund's average daily net assets: First $2 billion 0.0175% --------------------------------------------------------- Next $2.5 billion 0.0130% --------------------------------------------------------- Next $2.5 billion 0.0005% --------------------------------------------------------- In excess of $7 billion 0.0000% --------------------------------------------------------- In addition to the administrative services provided by MFS to the fund as described above, MFS is responsible for providing certain administrative services with respect to Class R2 shares. These services include various administrative, recordkeeping, and communication/educational services with respect to the retirement plans which invest in Class R2 shares, and may be provided directly by MFS or by a third party. The fund pays an annual 0.25% administrative service fee solely from the assets of Class R2 shares to MFS for the provision of these services. DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received $81,513 and $682 for the six months ended February 29, 2004, as its portion of the sales charge on sales of Class A and Class 529A shares of the fund, respectively. The Trustees have adopted a distribution plan for Class A, Class B, Class C, Class R1, Class R2, Class 529A, Class 529B and Class 529C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows: The fund's distribution plan provides that the fund will pay MFD an annual percentage of its average daily net assets attributable to certain share classes in order that MFD may pay expenses on behalf of the fund related to the distribution and servicing of its shares. These expenses include a service fee paid to each securities dealer that enters into a sales agreement with MFD based on the average daily net assets of accounts attributable to such dealers. These fees are calculated based on each class' average daily net assets. The maximum distribution and service fees for each class of shares are as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Distribution Fee 0.10% 0.75% 0.75% 0.25% 0.25% - ------------------------------------------------------------------------------------------------------------------ Service Fee 0.25% 0.25% 0.25% 0.25% 0.25% - ------------------------------------------------------------------------------------------------------------------ Total Distribution Plan 0.35% 1.00% 1.00% 0.50% 0.50% - ------------------------------------------------------------------------------------------------------------------ CLASS 529A CLASS 529B CLASS 529C Distribution Fee 0.25% 0.75% 0.75% - ------------------------------------------------------------------------------------------------------------------ Service Fee 0.25% 0.25% 0.25% - ------------------------------------------------------------------------------------------------------------------ Total Distribution Plan 0.50% 1.00% 1.00% - ------------------------------------------------------------------------------------------------------------------ MFD retains the service fee for accounts not attributable to a securities dealer, which for the six months ended February 29, 2004, amounted to: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Service Fee Retained by MFD $77,264 $1,976 $2,023 $-- $-- - -------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Service Fee Retained by MFD $100 $6 $26 - ------------------------------------------------------------------------------ Fees incurred under the distribution plan during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS R1 CLASS R2 Effective Annual Percentage Rates 0.25% 1.00% 1.00% 0.50% 0.50% - -------------------------------------------------------------------------------- CLASS 529A CLASS 529B CLASS 529C Effective Annual Percentage Rates 0.35% 1.00% 1.00% - -------------------------------------------------------------------------------- Payment of the 0.10% per annum Class A distribution fee will be implemented on such a date as the Trustees of the Trust may determine. Payment of the 0.15% per annum portion of the Class 529A distribution fee that is not currently being charged will be implemented on such a date as the Trustees of the Trust may determine. Certain Class A, Class C and Class 529C shares are subject to a contingent deferred sales charge in the event of a shareholder redemption within, for Class A shares, 12 months following the purchase, and, for Class C and 529C shares, the first year from the end of the calendar month of purchase. A contingent deferred sales charge is imposed on shareholder redemptions of Class B and Class 529B shares in the event of a shareholder redemption within six years from the end of the calendar month of purchase. MFD receives all contingent deferred sales charges. Contingent deferred sales charges imposed during the six months ended February 29, 2004, were as follows: CLASS A CLASS B CLASS C CLASS 529B CLASS 529C Contingent Deferred Sales Charges Imposed $46,748 $582,186 $6,077 $-- $-- - -------------------------------------------------------------------------------- The fund has and may from time to time enter into contracts with program managers and other parties which administer the tuition programs through which an investment in the fund's 529 share classes is made. The fund has entered into an agreement with MFD pursuant to which MFD receives an annual fee of up to 0.35% from the fund based solely upon the value of the fund's 529 share classes attributable to tuition programs to which MFD or a third party which contracts with MFD provides administrative services. The current fee has been established at 0.25% annually of average net assets of the fund's 529 share classes attributable to such programs. The fee may only be increased with the approval of the Board of Trustees that oversees the fund. The services provided by MFD or a third party with which MFD contracts include recordkeeping and tax reporting and account services, as well as services designed to maintain the program's compliance with the Internal Revenue Code and other regulatory requirements. SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of the fund's average daily net assets at an annual rate of 0.11%, which amounted to $1,141,385 for the six months ended February 29, 2004. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $582,600 for the six months ended February 29, 2004, as well as other expenses paid to unaffiliated vendors.

(6) LINE OF CREDIT The fund and other affiliated funds participate in an $800 million unsecured line of credit provided by a syndication of banks under a line of credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the bank's base rate plus 0.50%. In addition, a commitment fee, based on the average daily, unused portion of the line of credit, is allocated among the participating funds at the end of each calendar quarter. The commitment fee allocated to the fund for the six months ended February 29, 2004, was $6,823. The fund had no borrowings during the period. (7) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust IV, of which the fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.

Manning] As the firm's new Chief Executive Officer, I want to thank you for your continued trust in MFS and tell you about the series of actions we have taken since our recent settlements with the regulators. These actions are designed to enhance the governance structure of the MFS funds, tighten our business practices, and strengthen the management team at MFS. In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned veteran of the mutual fund industry, Bob has held prior positions as President of Fidelity Management & Research Company, as Associate General Counsel of the Securities and Exchange Commission, and as a visiting professor at Harvard Law School. In an effort to develop and implement policies that we believe will set a new standard in regulatory compliance, MFS has hired two new senior executives. Jeffrey Carp is joining us as General Counsel with responsibility for all of our legal affairs. Previously he was a senior partner with the law firm of Hale and Dorr LLP. Also joining MFS in the new position of Executive Vice President of Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal audit, and fund treasury. In the area of governance, we have taken steps to enhance the independence of our funds' boards of trustees to better protect the interests of shareholders. We have independent board chairs and at least 75% of the trustees are independent. The trustees will appoint not only their own counsel but also an independent compliance officer. This officer will assist the boards and their committees in monitoring the MFS funds' compliance with federal and state regulations. In February, MFS reached agreements with federal and state regulators to settle their administrative proceedings against the firm and two senior executives in connection with market timing and related issues. Under the terms of the settlements, we agreed to pay $225 million to compensate affected retail fund shareholders. The $225 million will be distributed in accordance with a distribution plan developed by an independent consultant. We have further agreed with state regulators to reduce management fees on certain funds we advise by approximately $25 million annually over the next five years and to pay an administrative fine of $1 million, which will be used for the purpose of investor education. We have introduced a set of policies designed to protect the MFS funds and MFS fund shareholders from market timing abuses. By July, all MFS retail funds, except money market funds, will have a 2% redemption fee on short-term trades. Our global, international, high-yield, mid- and small-cap funds will impose the 2% fee on redemptions or exchanges of fund shares made within 30 calendar days of a share purchase. For all other MFS funds, except money market funds, the 2% fee will be imposed on redemptions or exchanges made within 5 business days of a share purchase. See the fund prospectus for more information. We continue to use fair value pricing, a strategy that minimizes the potential for investors to take advantage of "stale" prices. These can occur, as one example, when funds own foreign securities whose prices close on overseas exchanges in different time zones. At the same time, we enhanced our monitoring of excessive trading. We did so by increasing our staff and updating our computer systems to improve our ability to detect excessive trading in our funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m. close on all trading, which would prevent the possibility of late trading. In March, MFS reached a second settlement with the SEC under an administrative proceeding resolving the SEC's investigation into how we disclosed brokerage allocation practices in connection with fund sales. According to the settlement order, we did not effectively disclose the potential conflict of interest that may arise from these arrangements. Under the terms of the settlement, MFS has agreed to pay one dollar in disgorgement and $50 million in penalty to MFS fund shareholders. The settlement noted that MFS had policies in place designed to obtain best execution of all trades of securities within MFS portfolios. This past November, MFS eliminated the above mentioned practice of directing brokerage commissions to certain firms in recognition of fund sales. Additionally, we announced in March that we would ban the use of soft dollars to acquire third-party securities research and market data. Soft dollars are permitted under federal securities laws. In fact, it is a common industry practice to use a portion of the brokerage commissions to pay for certain research and execution products and services that are provided to asset managers. MFS will now pay cash out of its own pocket for third-party research and market data. MFS continues to be financially strong, with more than U.S. $140 billion (as of 12/31/03) in assets under management, which continued to be stable during the first quarter of 2004. We also have the full support of our parent company, Sun Life Financial, an internationally diversified financial services firm that manages more than U.S. $269 billion (as of 12/31/03). We chose to settle these two proceedings with the SEC so we could concentrate on serving our fund shareholders. As Chief Investment Officer, my focus is on ensuring that our portfolio teams work closely together and take full advantage of all the resources available to them to deliver the best possible investment performance. As the inventor of the open-end mutual fund in America in 1924, MFS has a strong tradition and culture of innovation. By strengthening our business and governance practices, we believe we have an unprecedented opportunity to set a new standard in the mutual fund industry. As I look ahead, I do so with confidence. The collaboration among MFS employees, many of whom have worked at the firm for their entire careers, continues as we remain singularly dedicated to our clients. It has been our sincere privilege to serve you, and we thank you for the confidence that you have shown in MFS. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer MFS Investment Management(R) March 15, 2004 Note to Shareholders: On February 6, 2004, Jeffrey L. Shames retired as Chairman of MFS. Robert Pozen was named as non-executive Chairman. Also, on February 6, 2004, Robert J. Manning was appointed Chief Executive Officer, President, and Chief Investment Officer. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed. - -------------------------------------------------------------------------------- MFS ORIGINAL RESEARCH(R) - -------------------------------------------------------------------------------- THE MFS(R) DIFFERENCE For 80 years MFS has been offering investors clear paths to pursuing specific investment objectives. Today, millions of individuals and thousands of institutions all over the world look to MFS to manage their assets with insight and care. Our success, we believe, has to do with the fact that we see investors as people with plans, not just dollars to invest. When you invest with MFS, you invest with a company dedicated to helping you realize your long-term financial goals. INVESTORS CHOOSE MFS FOR OUR o global asset management expertise across all asset classes o time-tested money management process for pursuing consistent results o full spectrum of investment products backed by MFS Original Research(R) o resources and services that match real-life needs TURNING INFORMATION INTO OPPORTUNITY Sound investments begin with sound information. MFS has been doing its own research and analyzing findings in-house for decades. The process we use to uncover opportunity is called MFS Original Research(R). MFS ORIGINAL RESEARCH INVOLVES: o meeting with the management of 3,000 companies each year to assess their business plans and the managers' ability to execute those plans o making onsite visits to more than 2,000 companies annually to gain first-hand knowledge of their operations and products o analyzing financial statements and balance sheets o talking extensively with companies' customers and competitors o developing our own proprietary estimates of companies' earnings - -------------------------------------------------------------------------------- MANAGEMENT REVIEW - -------------------------------------------------------------------------------- MARKET ENVIRONMENT The reporting period began with an unsettled market environment characterized by high jobless claims, mixed economic news, and volatile energy prices. By the end of the six-month period on February 29, 2004, economic conditions appeared to be improving as jobless claims were down. However, energy prices still appeared high to us. In an effort to continue to stabilize prices and stimulate the economy, the Federal Reserve Board (the Fed) maintained the federal funds overnight borrowing rate at 1.00% throughout the period -- a 46-year low. The Fed maintained in February that it would "...continue to be patient..." before it began to raise rates. CONTINUED SHORT SUPPLY OF COMMERCIAL PAPER Despite signs of growing economic strength, the supply of commercial paper continued to be constrained by cautious corporate spending in our view. Businesses, taking advantage of low absolute yields, issued longer-term debt in place of commercial paper. FUND POSITIONING As of February 29, 2004, about 92% of MFS Money Market Fund was invested in commercial paper with the balance of the portfolio invested in U.S. government discount, and U.S. government agency notes. Discount agency notes and repurchase agreements collateralized by U.S. government agency discount notes form the core of MFS Government Money Market Fund. During this reporting period, when interest rates were at historical lows and the Fed continued its accommodative stance, we strategically targeted an average maturity range for the portfolio of 45 to 55 days. COMMITMENT TO QUALITY Regardless of market or economic conditions, we intend to maintain the funds' high quality as we focus on the funds' objectives of income, capital preservation, and liquidity.

THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE RESULTS. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. THE PERFORMANCE SHOWN DOES NOT REFLECT THE DEDUCTION OF TAXES, IF ANY, THAT A SHAREHOLDER WOULD PAY ON FUND DISTRIBUTIONS OR THE REDEMPTION OF FUND SHARES. MFS MONEY MARKET FUND(1)(2) MFS GOVERNMENT MONEY MARKET FUND(1)(2) 6-month total return: 0.23% 6-month total return: 0.17% - -------------------------------------------------------------------------------- 7-day current yield with and 7-day current yield with and without waiver: 0.40% without waiver: 0.28% - -------------------------------------------------------------------------------- NOTES TO PERFORMANCE SUMMARY Yields quoted are based on the latest seven days ended as of February 29, 2004, with dividends annualized. The yield quotations more closely reflect the current earnings of the portfolios than a total return quotation would. Performance results reflect any applicable expense subsidies and waivers in effect during the periods shown; without these, the results would have been less favorable. Please see the prospectus and financial statements for complete details. All results are historical and assume the reinvestment of dividends and capital gains.

(2) Investments in the portfolio are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the portfolio seeks to preserve the value of your investment, it is possible to lose money by investing in the portfolio. The portfolio's yield will fluctuate with changes in market conditions. These risks may increase share price volatility. Please see the prospectus for these and other risk considerations.

See notes to financial statements. - ------------------------------------------------------------------------------ NOTES TO FINANCIAL STATEMENTS (unaudited) - ------------------------------------------------------------------------------ (1) BUSINESS AND ORGANIZATION MFS Money Market Fund and MFS Government Money Market Fund (the funds) are each a diversified series of MFS Series Trust IV (the trust). The trust is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as an open-end management investment company. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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. INVESTMENT VALUATIONS - Money market instruments are valued at amortized cost, which the Trustees have determined in good faith approximates market value. The funds' use of amortized cost is subject to the funds' compliance with certain conditions as specified under Rule 2a-7 of the Investment Company Act of 1940. REPURCHASE AGREEMENTS - The funds may enter into repurchase agreements with institutions that each funds' investment adviser has determined are creditworthy. Each repurchase agreement is recorded at cost. Each fund requires that the securities collateral in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the funds to obtain those securities in the event of a default under the repurchase agreement. The funds' monitor, on a daily basis, the value of the collateral to ensure that its value, including accrued interest, is greater than amounts owed to the funds under each such repurchase agreement. The funds 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. 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 and accreted for financial statement purposes and tax reporting purposes in accordance with generally accepted accounting principles and federal tax regulations, respectively. FEES PAID INDIRECTLY - The funds' custody fee is reduced according to an arrangement that measures the value of cash deposited with the custodian by the fund. This amount for the six months ended February 29, 2004 is shown as a reduction of total expenses on the Statement of Operations. TAX MATTERS AND DISTRIBUTIONS - The funds' policy is to comply with the provisions of the Internal Revenue Code (the Code) applicable to regulated investment companies and to distribute to shareholders all of its net taxable income, including any net realized gain on investments. Accordingly, no provision for federal income or excise tax is provided. Distributions to shareholders are recorded on the ex-dividend date. The funds distinguish between distributions on a tax basis and a financial reporting basis and only distributions in excess of tax basis earnings and profits are reported in the financial statements as distributions from paid-in capital. Differences in the recognition or classification of income between the financial statements and tax earnings and profits, which result in temporary over-distributions for financial statement purposes, are classified as distributions in excess of net investment income or net realized gains. The tax character of distributions declared for the years ended August 31, 2003 and August 31, 2002 was as follows: Government Money Money Market Fund Market Fund 8/31/03 8/31/02 8/31/03 8/31/02 Distributions declared from ordinary income $15,391,590 $25,276,859 $772,690 $927,415 - -------------------------------------------------------------------------------- As of August 31, 2003, the components of distributable earnings on a tax basis were as follows: Government Money Money Market Fund Market Fund 8/31/03 8/31/03 Undistributed ordinary income $236,442 $2,606 - -------------------------------------------------------------------------------- Capital loss carryforward (11,496) -- - -------------------------------------------------------------------------------- Other temporary differences (224,946) (10,319) - -------------------------------------------------------------------------------- For federal income tax purposes, the capital loss carryforward may be applied against any net taxable realized gains of each succeeding year until the earlier of its utilization or expiration on August 31, 2011 for MFS Money Market Fund. (3) TRANSACTIONS WITH AFFILIATES INVESTMENT ADVISER - Each fund has an investment advisory agreement with Massachusetts Financial Services Company (MFS) to provide overall investment advisory and administrative services, and general office facilities. The management fee is computed daily and paid monthly at the following annual rates: First $300 million of average net assets 0.50% ------------------------------------------------------- Next $400 million of average net assets 0.45% ------------------------------------------------------- Next $400 million of average net assets 0.40% ------------------------------------------------------- Average net assets in excess of $1 billion 0.35% ------------------------------------------------------- Management fees incurred for the six months ended February 29, 2004 were 0.44% and 0.50% of average daily net assets on an annualized basis for the MFS Money Market Fund and the MFS Government Money Market Fund, respectively. As part of the settlement agreement with the New York Attorney General concerning market timing and related matters, MFS has agreed to reduce each fund's management fee to 0.15% of average daily net assets for the period March 1, 2004 through February 28, 2009. During this time period, the Board of Trustees will continue to review the appropriateness of all advisory fees in accordance with their oversight responsibilities. After February 28, 2009 the management fees will be determined in accordance with then existing review policies approved by the Board of Trustees overseeing the funds. The funds pay compensation to the Independent Trustees ("Trustees") in the form of both a retainer and attendance fees, and pay no compensation directly to their Trustees who are officers of the investment adviser, or to officers of the funds, all of whom receive remuneration for their services to the funds from MFS. Certain officers and Trustees of the funds are officers or directors of MFS and MFS Service Center, Inc. (MFSC). The funds have an unfunded, defined benefit plan for retired Trustees. Included in Trustees' compensation is a pension expense of $2,991 and $590 for retired Trustees for the six months ended February 29, 2004 for the MFS Money Market Fund and MFS Government Money Market Fund, respectively. ADMINISTRATOR - Each fund has an administrative services agreement with MFS to provide the funds with certain financial, legal, shareholder communications, compliance, and other administrative services. As a partial reimbursement for the cost of providing these services, each fund pays MFS an administrative fee up to the following annual percentage rates of each fund's average daily net assets: First $2 billion 0.0175% ------------------------------------------------------- Next $2.5 billion 0.0130% ------------------------------------------------------- Next $2.5 billion 0.0005% ------------------------------------------------------- In excess of $7 billion 0.0000% ------------------------------------------------------- SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder servicing agent. The fee is calculated as a percentage of each fund's average daily net assets at an annual rate of 0.11%, which amounted to $569,639 and $66,556 for the six months ended February 29, 2004 for the MFS Money Market Fund and MFS Government Money Market Fund, respectively. Also included in shareholder servicing costs are out-of-pocket expenses, paid to MFSC, which amounted to $37,182 and $1,662 for the six months ended February 29, 2004 for the MFS Money Market Fund and MFS Government Money Market Fund, respectively, as well as other expenses paid to unaffiliated vendors. (4) PORTFOLIO SECURITIES Purchases and sales of money market investments, exclusive of securities subject to repurchase agreements, for MFS Money Market Fund aggregated $6,448,691,350 and $7,635,082,569 respectively. Purchases and sales of money market investments, exclusive of securities subject to repurchase agreements, for MFS Government Money Market Fund aggregated $1,584,034,000 and $1,586,880,000 respectively. (5) SHARES OF BENEFICIAL INTEREST The funds' Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares of beneficial interest. (6) LINE OF CREDIT The funds and other affiliated funds participate in an $800 million unsecured line of credit provided by a syndication of banks under a line of credit agreement. Borrowings may be made for temporary financing needs. Interest is charged to each fund, based on its borrowings, at a rate equal to the bank's base rate. In addition, a commitment fee, based on the average daily unused portion of the line of credit, is allocated among the participating funds at the end of each quarter. The commitment fee allocated to the funds for the six months ended February 29, 2004, was $3,004 and $473 for the MFS Money Market Fund and the MFS Government Money Market Fund, respectively. The funds had no borrowings during the period. (7) LEGAL PROCEEDINGS On March 31, 2004, MFS settled an administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. Under the terms of the settlement, in which MFS neither admitted nor denied any wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50 million in penalty to certain MFS funds, pursuant to a plan to be approved by an independent distribution consultant. The agreement with the SEC is reflected in an order of the SEC. The settlement order states that MFS failed to adequately disclose to the Boards of Trustees and to shareholders of the MFS funds the specifics of its preferred arrangements with certain brokerage firms selling MFS fund shares. The settlement order states that MFS had in place policies designed to obtain best execution of all fund trades. As part of the settlement, MFS also agreed to retain an independent compliance consultant to review the completeness of its disclosure to fund trustees and to fund shareholders of strategic alliances between MFS or its affiliates and broker-dealers and other financial advisers who support the sale of fund shares. The brokerage allocation practices which were the subject of this proceeding were discontinued by MFS in November 2003. In addition, in February, 2004, MFS reached agreement with the Securities and Exchange Commission ("SEC"), the New York Attorney General ("NYAG") and the Bureau of Securities Regulation of the State of New Hampshire ("NH") to settle administrative proceedings alleging false and misleading information in certain MFS fund prospectuses regarding market timing and related matters (the "February Settlements"). These regulators alleged that prospectus language for certain MFS funds was false and misleading because, although the prospectuses for those funds in the regulators' view indicated that the funds prohibited market timing, MFS did not limit trading activity in 11 domestic large cap stock, high grade bond and money market funds. MFS' former Chief Executive Officer, John W. Ballen, and former President, Kevin R. Parke, have also reached agreement with the SEC (Messrs. Ballen and Parke resigned their director and officer positions with MFS on February 13, 2004). Under the terms of the February Settlements, MFS and the executives neither admit nor deny wrongdoing. Under the terms of the February Settlements, a $225 million pool has been established for distribution to shareholders in certain of the MFS funds offered to retail investors ("Retail Funds"), which has been funded by MFS and of which $50 million is characterized as a penalty. This pool will be distributed in accordance with a methodology developed by an independent distribution consultant in consultation with MFS and the Boards of Trustees of the Retail Funds, and acceptable to the SEC. MFS has further agreed with the NYAG to reduce its management fees in the aggregate amount of approximately $25 million annually over the next five years, and not to increase certain management fees during this period. MFS has also paid an administrative fine to NH in the amount of $1 million, which will be used for investor education purposes (NH will retain $250,000 and $750,000 will be contributed to the North American Securities Administrators Association's Investor Protection Trust). In addition, MFS and the Retail Funds will adopt certain governance changes. Messrs. Ballen and Parke have agreed to temporary suspensions from association with any registered investment company or investment adviser, will pay approximately $315,000 each to the SEC, and resigned their positions as trustees of all MFS funds, and Mr. Ballen resigned his position as President of all MFS funds, effective February 6, 2004. Messrs. Ballen and Parke will not be returning to MFS or the MFS funds after their suspensions. Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the Trustees of these MFS funds, and certain officers of MFS have been named as defendants in multiple lawsuits filed in federal and state courts. The lawsuits variously have been commenced as class actions or individual actions on behalf of investors who purchased, held or redeemed shares of the funds during specified periods, as class actions on behalf of participants in certain retirement plan accounts, or as derivative actions on behalf of the MFS funds. The lawsuits generally allege that some or all of the defendants (i) permitted or acquiesced in market timing and/or late trading in some of the MFS funds, inadequately disclosed MFS' internal policies concerning market timing and such matters, and received excessive compensation as fiduciaries to the MFS fund, or (ii) permitted or acquiesced in the improper use of fund assets by MFS to support the distribution of fund shares and inadequately disclosed MFS' use of fund assets in this manner. The actions assert that some or all of the defendants violated the federal securities laws, including the Securities Act of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of 1940 and the Investment Advisers Act of 1940, the Employee Retirement Income Security Act of 1974, as well as fiduciary duties and other violations of common law. The lawsuits seek unspecified compensatory damages. Insofar as any of the actions is appropriately brought derivatively on behalf of any of the MFS funds, any recovery will inure to the benefit of the funds. The defendants are reviewing the allegations of the multiple complaints and will respond appropriately. Additional lawsuits based on similar allegations may be filed in the future. Any potential resolution of these matters may include, but not be limited to, judgments or settlements for damages against MFS, the MFS funds, or any other named defendant. As noted above, as part of the regulatory settlements, MFS has established a restitution pool in the amount of $225 million to compensate certain shareholders of the Retail Funds for damages that they allegedly sustained as a result of market timing or late trading in certain of the funds, and will pay $50 million to compensate certain MFS funds based upon the amount of brokerage commissions allocated in recognition of fund sales. It is not clear whether these amounts will be sufficient to compensate shareholders for all of the damage they allegedly sustained, whether certain shareholders or putative class members may have additional claims to compensation, or whether the damages that may be awarded in any of the actions will exceed these amounts. In the event the MFS funds incur any losses, costs or expenses in connection with such lawsuits, the Boards of Trustees of the affected funds may pursue claims on behalf of such funds against any party that may have liability to the funds in respect thereof. Review of these matters by the independent Trustees of the MFS funds and their counsel is continuing. There can be no assurance that these regulatory actions and lawsuits, or the adverse publicity associated with these developments will not result in increased fund redemptions, reduced sales of fund shares, or other adverse consequences to the funds. - -------------------------------------------------------------------------------------------------------------- TRUSTEES AND OFFICERS - -------------------------------------------------------------------------------------------------------------- The following tables present certain information regarding the Trustees and officers of MFS Series Trust IV, of which each fund is a series, including their principal occupations, which, unless specific dates are shown, are of more than five years' duration, although the titles may not have been the same throughout.
