Manning] Dear Shareholders, Most investors are familiar with the basic principles of investing - focus on the long term and keep your assets diversified across different investment categories. Still, it is surprising how often we forget these basic lessons. Certainly, the dot-com euphoria that overtook Wall Street in the late 1990s had many people hoping they could become millionaires overnight. But the market decline that started in the spring of 2000 taught everyone how misguided those hopes had been. Now, less than five years after the market taught a harsh lesson in the follies of speculative investing, we are seeing a number of trends that suggest many investors, including professionals, are hoping for overnight miracles again. We see a steady stream of market "gurus" on television news shows, promising to teach amateur investors the strategies that will allow them to get rich quick. Hedge funds - which by their nature move in and out of investments rapidly - have soared in popularity over the past five years. We are reminded every day that we live in a "what have you done for me lately?" world, but this mindset should not influence how we invest and manage our money. In fact, investors often fall short of their goals because they trade in and out of investments too frequently and at inopportune times. Throughout our entire 80-year history, MFS" money management process has focused on long-term investment opportunities. We firmly believe that one of the best ways to realize long-term financial goals - be it a college education, a comfortable retirement, or a secure family legacy - is to follow a three-pronged approach that focuses on longer time horizons. Allocate holdings across the major asset classes - including stocks, bonds, and cash. Diversify within each class to take advantage of different market segments and investing styles. And rebalance assets regularly to maintain a desired asset allocation.* This long-term approach requires diligence and patience, two traits that in our experience are essential to capitalizing on the many opportunities the financial markets can offer. Respectfully, /s/ Robert J. Manning Robert J. Manning Chief Executive Officer and Chief Investment Officer MFS Investment Management(R) October 17, 2005 * Asset allocation, diversification, and rebalancing does not guarantee a profit or protect against a loss. The opinions expressed in this letter are those of MFS, and no forecasts can be guaranteed.

If not rated by Moody's, the rating will be that assigned by Standard & Poor's. Likewise, if not assigned a rating by Standard & Poor's, it will be based on the rating assigned by Fitch, Inc. For those portfolios that hold a security which is not rated by any of the three agencies, the security if considered Not Rated. Holdings in U.S. Treasuries and mortgage-backed securities, if any, are included in a "AAA"-rating category. Percentages are based on market value of investments as of 8/31/05. *** The average maturity shown is calculated using the final stated maturity on the portfolio's holdings without taking into account any holdings which have been pre- refunded to an earlier date or which have a mandatory put date prior to the stated maturity. The average life shown takes into account these earlier dates. **** The Portfolio Average Credit Quality is based upon a market weighted average of portfolio holdings. Percentages are based on net assets as of 8/31/05, unless otherwise noted. The portfolio is actively managed, and current holdings may be different. EXPENSE TABLE FUND EXPENSES BORNE BY THE SHAREHOLDERS DURING THE PERIOD, MARCH 1, 2005 THROUGH AUGUST 31, 2005. As a shareholder of the fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on certain purchase or redemption payments and redemption fees on certain exchanges and redemptions, and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period March 1, 2005 through August 31, 2005. ACTUAL EXPENSES The first line for each share class in the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line for each share class in the table below provides information about hypothetical account values and hypothetical expenses based on the fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption fees. Therefore, the second line for each share class in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - -------------------------------------------------------------------------------- Expenses Paid During Annualized Beginning Ending Period** Share Expense Account Value Account Value 12/01/04- Class Ratio 12/01/04 5/31/05 5/31/05 - -------------------------------------------------------------------------------- Actual 0.79% $1,000.00 $1,026.70 $4.04 A ------------------------------------------------------------------- Hypothetical* 0.79% $1,000.00 $1,021.22 $4.02 - -------------------------------------------------------------------------------- Actual 1.54% $1,000.00 $1,022.90 $7.85 B ------------------------------------------------------------------- Hypothetical* 1.54% $1,000.00 $1,017.44 $7.83 - -------------------------------------------------------------------------------- Actual 1.54% $1,000.00 $1,022.90 $7.85 C ------------------------------------------------------------------- Hypothetical* 1.54% $1,000.00 $1,017.44 $7.83 - -------------------------------------------------------------------------------- Actual 0.55% $1,000.00 $1,028.00 $2.81 I ------------------------------------------------------------------- Hypothetical* 0.55% $1,000.00 $1,022.43 $2.80 - -------------------------------------------------------------------------------- R Actual 1.04% $1,000.00 $1,024.40 $5.31 (formerly R1)------------------------------------------------------------------- Hypothetical* 1.04% $1,000.00 $1,019.96 $5.30 - -------------------------------------------------------------------------------- Actual 1.73% $1,000.00 $1,022.10 $8.82 R1 ------------------------------------------------------------------- Hypothetical* 1.73% $1,000.00 $1,016.48 $8.79 - -------------------------------------------------------------------------------- Actual 1.44% $1,000.00 $1,023.30 $7.34 R2 ------------------------------------------------------------------- Hypothetical* 1.44% $1,000.00 $1,017.95 $7.32 - -------------------------------------------------------------------------------- R3 Actual 1.29% $1,000.00 $1,023.10 $6.58 (formerly R2)------------------------------------------------------------------- Hypothetical* 1.29% $1,000.00 $1,018.70 $6.56 - -------------------------------------------------------------------------------- Actual 0.94% $1,000.00 $1,026.10 $4.80 R4 ------------------------------------------------------------------- Hypothetical* 0.94% $1,000.00 $1,020.47 $4.79 - -------------------------------------------------------------------------------- Actual 0.63% $1,000.00 $1,027.40 $3.22 R5 ------------------------------------------------------------------- Hypothetical* 0.63% $1,000.00 $1,022.03 $3.21 - -------------------------------------------------------------------------------- Actual 1.14% $1,000.00 $1,023.90 $5.82 529A ------------------------------------------------------------------- Hypothetical* 1.14% $1,000.00 $1,019.46 $5.80 - -------------------------------------------------------------------------------- Actual 1.78% $1,000.00 $1,020.60 $9.07 529B ------------------------------------------------------------------- Hypothetical* 1.78% $1,000.00 $1,016.23 $9.05 - -------------------------------------------------------------------------------- Actual 1.79% $1,000.00 $1,020.60 $9.12 529C ------------------------------------------------------------------- Hypothetical* 1.79% $1,000.00 $1,016.18 $9.10 - -------------------------------------------------------------------------------- * 5% class return per year before expenses. ** Expenses paid is equal to each class" annualized expense ratio, as shown above, multiplied by the average account value over the period, multiplied by the number of days in the period, divided by the number of days in the year.

(ct) The per share amount is not in accordance with the net realized and unrealized gain/loss for the period because of the timing of sales of fund shares and the amount of per share realized and unrealized gains and losses at such time. (+) Total returns do not include any applicable sales charges. (S) Effective March 1, 2001, the fund adopted the provisions of the AICPA Audit and Accounting Guide for Investment Companies and began amortizing and accreting all premiums and discounts on debt securities. Per share data and ratios for periods prior to March 1, 2001 have not been restated to reflect this change. = Redemption fees charged by the fund during this period resulted in a per share impact of less than $0.01. @ Due to a revision, certain amounts for the year ended February 28, 2005 have been changed from what was previously reported. The impact of the revision was an increase to the ratio of net investment income to average net assets and a corresponding decrease to the ratio of expenses to average net assets. Additionally, the revision resulted in rounding the net asset value for certain classes up to the next cent, increasing total return for these classes. As a result of these revised net asset values, no shareholder accounts were materially effected. The impact for each share class is summarized as follows: Financial Highlights - continued INCREASE IN INCREASE IN NET NET ASSET VALUE INVESTMENT DECREASE IN PER SHARE INCREASE TO SHARE CLASS INCOME RATIO EXPENSE RATIO (ROUNDED) TOTAL RETURN Class A 0.04% 0.04% N/A N/A Class B 0.03% 0.03% N/A N/A Class C 0.03% 0.03% N/A N/A Class I 0.05% 0.05% $0.01 0.11% Class R (formerly Class R1) 0.05% 0.05% $0.01 0.10% Class R3 (formerly Class R2) 0.10% 0.10% $0.01 0.11% Class 529A 0.04% 0.04% $0.01 0.11% Class 529B 0.03% 0.03% $0.01 0.10% Class 529C 0.04% 0.04% $0.01 0.10% SEE NOTES TO FINANCIAL STATEMENTS NOTES TO FINANCIAL STATEMENTS (unaudited) (1) BUSINESS AND ORGANIZATION MFS Government Securities Fund (the fund) is organized as a Massachusetts business trust and is registered under the Investment Company Act of 1940, as amended, as a diversified open-end management investment company. (2) SIGNIFICANT ACCOUNTING POLICIES GENERAL - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. INVESTMENT VALUATIONS - 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. Futures contracts are valued at the settlement price as reported by an independent pricing service on the primary exchange on which they are traded. 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 approximates market value as determined by the Board of Trustees. When pricing service information or market quotations are not readily available, securities are priced at fair value as determined under the direction of the Board of Trustees. 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. FUTURES CONTRACTS - The fund may enter into futures contracts for the delayed delivery of securities or currency, or contracts based on financial indices at a fixed price on a future date. In entering such contracts, the fund is required to deposit with the broker, either in cash or securities, an amount equal to a certain percentage of the contract amount. Subsequent payments are made or received by the fund each day, depending on the daily fluctuations in the value of the contract, and are recorded for financial statement purposes as unrealized gains or losses by the fund. The fund's investment in futures contracts is designed to hedge against anticipated future changes in interest or exchange rates or securities prices. Investments in interest rate futures for purposes other than hedging may be made to modify the duration of the portfolio without incurring the additional transaction costs involved in buying and selling the underlying securities. Investments in currency futures for purposes other than hedging may be made to change the fund's relative position in one or more currencies without buying and selling portfolio assets. Investments in equity index contracts or contracts on related options for purposes other than hedging, may be made when the fund has cash on hand and wishes to participate in anticipated market appreciation while the cash is being invested. Should interest or exchange rates or securities prices move unexpectedly, the fund may not achieve the anticipated benefits of the futures contracts and may realize a loss. SHORT TERM FEES - For purchases made on or after July 1, 2004 and before April 1, 2005, the fund charged a 2% redemption fee (which is retained by the fund) on proceeds from Class A, Class B, Class C, and Class I shares redeemed or exchanged within 5 business days following their acquisition (either by purchase or exchange). Effective April 1, 2005, the fund no longer charges a redemption fee. See the fund's prospectus for details. Any redemption fees charged are accounted for as an addition to paid-in capital. INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the trade date. 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. Interest income is recorded on the accrual basis. All premium and discount is amortized or accreted for financial statement purposes in accordance with U.S. generally accepted accounting principles. All discount is accreted for tax reporting purposes as required by federal income tax regulations. The fund may enter into "TBA" (to be announced) purchase commitments to purchase securities for a fixed unit price at a future date. Although the unit price has been established, the principal value has not been finalized. However, the principal amount of the commitments will not fluctuate more than 0.01%. The fund holds, and maintains until settlement date, cash or high-grade debt obligations in an amount sufficient to meet the purchase price, or the fund may enter into offsetting contracts for the forward sale of other securities it owns. Income on the securities will not be earned until settlement date. TBA purchase commitments may be considered securities in themselves, and involve a risk of loss if the value of the security to be purchased declines prior to settlement date, which is in addition to the risk of decline in the value of the fund's other assets. Unsettled TBA purchase commitments are valued at the current market value of the underlying securities. The fund may enter into "TBA" (to be announced) sale commitments to hedge its portfolio positions or to sell mortgage-backed securities it owns under delayed delivery arrangements. Proceeds of TBA sale commitments are not received until the contractual settlement date. During the time a TBA sale commitment is outstanding, equivalent deliverable securities, or an offsetting TBA purchase commitment deliverable on or before the sale commitment date, are held as "cover" for the transaction. 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 August 31, 2005, 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 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 derivatives, amortization and accretion on debt securities, wash sales, and non-deductible pension expense. The tax character of distributions declared for the years ended February 28, 2005 and February 29, 2004 was as follows: 2/28/05 2/29/04 Distributions declared from: Ordinary income $48,761,052 $55,327,053 As of February 28, 2005, the components of distributable earnings (accumulated losses) on a tax basis were as follows: Undistributed ordinary income $1,528,214 Capital loss carryforward (57,454,896) Unrealized appreciation (depreciation) 898,761 Other temporary differences (5,288,879) 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. EXPIRATION DATE February 28, 2006 $(5,100,994) February 28, 2007 (5,253,445) February 29, 2008 (15,270,459) February 28, 2009 (3,477,230) February 28, 2011 (11,527,172) February 29, 2012 (5,729,829) February 28, 2013 (11,095,767) ---------------------------------------------------------- Total $(57,454,896) The availability of a portion of the capital loss carryforwards, which were acquired on November 19, 2004, in connection with the MFS Government Mortgage Fund merger, may be limited in a given year. 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 and Class 529B shares will convert to Class A and Class 529A shares, respectively, approximately eight years after purchase. OTHER - Due to a revision to miscellaneous expenses, certain amounts on the Statement of Changes in Net Assets and Financial Highlights for the year ended February 28, 2005, have been changed from what was previously reported. The impact of the revision was to reduce expenses related to this item and thereby increase net investment income, changes in net assets from operations and net assets at end of period for the year ended February 28, 2005, by $541,341. (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 an annual rate of 0.40% of the fund's average daily net assets. As part of a settlement agreement with the New York Attorney General concerning market timing and related matters, MFS has agreed to reduce the management fee to 0.30% of the fund's average daily net assets for the period March 1, 2004 through February 28, 2009. For the six months ended August 31, 2005, this waiver is reflected as a reduction of total expenses in the Statement of Operations. The management fee incurred for the six months ended August 31, 2005 was equivalent to an annual effective rate of 0.30% of the fund's average daily net assets. The investment adviser has contractually agreed to pay a portion of the fund's operating expenses, exclusive of management, distribution and service, retirement plan administration and services, program manager, and certain other fees and expenses, such that operating expenses do not exceed 0.25% annually of the fund's average daily net assets. This is reflected as a reduction of total expenses in the Statement of Operations. This contractual fee arrangement will continue until June 30, 2006, unless the fund's Board of Trustees consents to an earlier revision or termination of this agreement. DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly owned subsidiary of MFS, as distributor, received $29,823 and $156 for the six months ended August 31, 2005, as its portion of the initial sales charge on sales of Class A and Class 529A shares of the fund, respectively. The Board of Trustees has adopted a distribution plan for certain class shares pursuant to Rule 12b-1 of the Investment Company Act of 1940. The fund's distribution plan provides that the fund will pay MFD for services provided by MFD and financial intermediaries in connection with the distribution and servicing of certain share classes. One component of the plan is a distribution fee paid to and retained by MFD. Another component of the plan is a service fee paid to MFD which subsequently pays a portion of this fee to financial intermediaries that enter into sales or service agreements with MFD, or its affiliates, based on the average daily net assets of accounts attributable to such intermediaries.

The fund is one of several mutual funds in which the MFS fund-of-funds may invest. The MFS fund-of-funds do not invest in the underlying MFS funds for the purpose of exercising management or control. At the end of the period, the MFS Conservative Allocation Fund, the MFS Moderate Allocation Fund and MFS Growth Allocation Fund were the owners of record of approximately 4%, 11% and 6% respectively, of the value of outstanding voting shares. (6) LINE OF CREDIT The fund and other affiliated funds participate in a $1 billion unsecured line of credit provided by a syndication of banks under a 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 Federal Reserve funds rate plus 0.35%. 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 August 31, 2005 was $7,660 and is included in miscellaneous expense. The fund had no significant borrowings during the six months ended August 31, 2005. (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 and foreign currency exchange rates. These financial instruments include futures contracts. 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.

(8) ACQUISITIONS At close of business on November 19, 2004, the fund acquired all of the assets and liabilities of the MFS Government Mortgage Fund. The acquisition was accomplished by a tax-free exchange of 48,701,178 shares of the fund (valued at $473,323,224) for all of the assets and liabilities of the MFS Government Mortgage Fund. MFS Government Mortgage Fund then converted all of its outstanding shares for the shares of the fund and distributed those shares to its shareholders. MFS Government Mortgage Fund's net assets on that date were $473,323,224, including $3,693,881 of unrealized appreciation, $157,151 of accumulated distributions in excess of net investment income, and $31,781,771 of accumulated net realized loss on investments. These assets were combined with those of the fund. The aggregate net assets of the fund after the acquisition were $1,217,628,851.

The Trustees consider matters bearing on the Fund and its advisory arrangements at their meetings throughout the year, including a review of performance data at each regular meeting. In addition, the independent Trustees met several times over the course of three months beginning in May and ending in July, 2005 ("contract review meetings") for the specific purpose of considering whether to approve the continuation of the investment advisory agreement for the Fund and the other investment companies that the Board oversees (the "MFS Funds"). The independent Trustees were assisted in their evaluation of the Fund's investment advisory agreement by independent legal counsel, from whom they received separate legal advice and with whom they met separately from MFS during various contract review meetings. The independent Trustees were also assisted in this process by the MFS Funds" Independent Chief Compliance Officer, a full-time senior officer appointed by and reporting to the independent Trustees. In connection with their deliberations regarding the continuation of the investment advisory agreement, the Trustees, including the independent Trustees, considered such information and factors as they believed, in light of the legal advice furnished to them and their own business judgment, to be relevant. The investment advisory agreement for the Fund was considered separately, although the Trustees also took into account the common interests of all MFS Funds in their review. As described below, the Trustees considered the nature, quality, and extent of the various investment advisory, administrative, and shareholder services performed by MFS under the existing investment advisory agreement and other arrangements with the Fund. In connection with their contract review meetings, the Trustees received and relied upon materials which included, among other items: (i) information provided by Lipper Inc. on the investment performance of the Fund for various time periods ended December 31, 2004 and the investment performance of a group of funds with substantially similar investment classifications/objectives (the "Lipper performance universe"), as well as the investment performance of a group of funds identified by objective criteria suggested by MFS ("peer funds"), (ii) information provided by Lipper Inc. on the Fund's advisory fees and other expenses and the advisory fees and other expenses of comparable funds identified by Lipper (the "Lipper expense group"), as well as the advisory fees and other expenses of peer funds identified by objective criteria suggested by MFS, (iii) information provided by MFS on the advisory fees of comparable portfolios of other clients of MFS, including institutional separate account and other clients, (iv) information as to whether and to what extent applicable expense waivers, reimbursements or fee "breakpoints" are observed for the Fund, (v) information regarding MFS" financial results and financial condition, including MFS" and certain of its affiliates" estimated profitability from services performed for the Fund and the MFS Funds as a whole, (vi) MFS" views regarding the outlook for the mutual fund industry and the strategic business plans of MFS, (vii) descriptions of various functions performed by MFS for the Funds, such as compliance monitoring and portfolio trading practices, and (viii) information regarding the overall organization of MFS, including information about MFS" senior management and other personnel providing investment advisory, administrative and other services to the Fund and the other MFS Funds. The comparative performance, fee and expense information prepared and provided by Lipper Inc. was not independently verified and the independent Trustees did not independently verify any information provided to them by MFS. The Trustees" conclusion as to the continuation of the investment advisory agreement was based on a comprehensive consideration of all information provided to the Trustees and not the result of any single factor. Some of the factors that figured particularly in the Trustees" deliberations are described below, although individual Trustees may have evaluated the information presented differently from one another, giving different weights to various factors. It is also important to recognize that the fee arrangements for the Fund and other MFS Funds are the result of years of review and discussion between the independent Trustees and MFS, that certain aspects of such arrangements may receive greater scrutiny in some years than others, and that the Trustees" conclusions may be based, in part, on their consideration of these same arrangements during the course of the year and in prior years. Based on information provided by Lipper Inc. and MFS, the Trustees reviewed the Fund's total return investment performance as well as the performance of peer groups of funds over various time periods. The Trustees placed particular emphasis on the total return performance of the Fund's Class A shares in comparison to the performance of funds in its Lipper performance universe over the three-year period ended December 31, 2004, which the Trustees believed was a long enough period to reflect differing market conditions. The Fund's performance was in the 48th percentile relative to the other funds in the universe for this three-year period (the 1st percentile being the best performers and the 100th percentile being the worst performers). The total return performance of the Fund's Class A shares was in the 40th percentile for the one-year period and the 42nd percentile for the five-year period ended December 31, 2004 relative to the Lipper performance universe. Because of the passage of time, these performance results are likely to differ from the performance results for more recent periods, including those shown elsewhere in this report. In the course of their deliberations, the Trustees took into account information provided by MFS in connection with the contract review meetings, as well as during investment review meetings conducted with portfolio management personnel during the course of the year regarding the Fund's performance. After reviewing these and related factors, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreement, that they were satisfied with MFS" responses and efforts relating to investment performance. In assessing the reasonableness of the Fund's advisory fee, the Trustees considered, among other information, the Fund's advisory fee and the total expense ratio of the Fund's Class A shares as a percentage of average net assets and the advisory fee and total expense ratios of peer groups of funds based on information provided by Lipper Inc. and MFS. The Trustees considered whether the Fund was subject to any fee waivers or reductions or expense limitations. The Trustees also considered that, according to the Lipper data, the Fund's effective advisory fee rate was lower than the Lipper expense group median, and the Fund's total expense ratio was approximately at the Lipper expense group median. The Trustees also considered the advisory fees charged by MFS to institutional accounts. In comparing these fees, the Trustees considered information provided by MFS as to the generally broader scope of services provided by MFS to the Fund in comparison to institutional accounts, the higher demands placed on MFS" investment personnel and trading infrastructure as a result of the daily cash in-flows and out-flows of the Fund, and the impact on MFS and expenses associated with the more extensive regulatory regime to which the Fund is subject in comparison to institutional accounts. The Trustees also considered whether the Fund is likely to benefit from any economies of scale in the management of the Fund in the event of growth in assets of the Fund. They noted that the Fund's advisory fee rate schedule is not currently subject to any breakpoints. Taking into account fee waivers or reductions or expense limitations, if any, the Trustees determined not to recommend any advisory fee breakpoints for the Fund at this time. The Trustees also considered information prepared by MFS relating to MFS" costs and profits with respect to the Fund, the MFS Funds considered as a group, and other investment companies and accounts advised by MFS, as well as MFS" methodologies used to determine and allocate its costs to the MFS Funds, the Fund and other accounts and products for purposes of estimating profitability. After reviewing these and other factors described herein, the Trustees concluded, within the context of their overall conclusions regarding the investment advisory agreement, that the advisory fees charged to the Fund represent reasonable compensation in light of the nature and quality of the services being provided by MFS to the Fund. In addition, the Trustees considered MFS" resources and related efforts to continue to retain, attract and motivate capable personnel to serve the Fund. The Trustees also considered current and developing conditions in the financial services industry, including the entry into the industry of large and well-capitalized companies which are spending, and appear to be prepared to continue to spend, substantial sums to engage personnel and to provide services to competing investment companies. In this regard, the Trustees also considered the financial resources of MFS and its ultimate parent, Sun Life Financial Inc. The Trustees also considered the advantages and possible disadvantages to the Fund of having an adviser which also serves other investment companies as well as other accounts. The Trustees also considered the nature, quality, cost, and extent of administrative, transfer agency, and distribution services provided to the Fund by MFS and its affiliates under agreements and plans other than the investment advisory agreement, including any 12b-1 fees the Fund pays to MFS Fund Distributors, Inc., an affiliate of MFS. The Trustees also considered the nature, extent and quality of certain other services MFS performs or arranges for on the Fund's behalf, including securities lending programs, directed expense payment programs, class action recovery programs, and MFS" interaction with third-party service providers, principally custodians and sub-custodians. The Trustees concluded that the various non-advisory services provided by MFS and its affiliates on behalf of the Funds were satisfactory. The Trustees also considered benefits to MFS from the use of the Fund's portfolio brokerage commissions to pay for research and other similar services (including MFS" general policy to pay directly for third-party research), and various other factors. Additionally, the Trustees considered so-called "fall- out benefits" to MFS such as reputational value derived from serving as investment manager to the Fund. Based on their evaluation of factors that they deemed to be material, including those factors described above, the Board of Trustees, including a majority of the independent Trustees, concluded that the Fund's investment advisory agreement with MFS should be continued for an additional one-year period, commencing August 1, 2005. A discussion regarding the Board's most recent review and renewal of the Fund's investment advisory agreement will be available on or before December 1, 2005 by clicking on the fund's name under "Select a fund" on the MFS website (mfs.com).
