Distribution Fees

The Distribution Plan provides that the Fund may pay MFD a distribution fee based on the average daily net assets attributable to the Designated Class as partial consideration for distribution services performed and expenses incurred in the performance of MFD’s obligations under its distribution agreement with the Fund. Distribution fees compensate MFD and/or financial intermediaries for their expenses in connection with the distribution of Fund shares, including, but not limited to, commissions to financial intermediaries, printing prospectuses and reports used for sales purposes, the preparation and printing of sales literature, personnel, travel, office expense and equipment, payments made to wholesalers employed by MFD (employees may receive additional compensation if they meet certain targets for sales of one or more MFS Funds), and other distribution-related expenses. The amount of the distribution fee paid by the Fund with respect to each class differs under the Distribution Plan, as does the use by MFD of such distribution fees. While the amount of compensation received by MFD in the form of distribution fees during any year may be more or less than the expenses incurred by MFD under its distribution agreement with the Fund, the Fund is not liable to MFD for any losses MFD may incur in performing services under its Distribution Agreement with the Fund.

FINANCIAL INTERMEDIARY COMPENSATION

MFD and/or its affiliates may pay commissions, Rule 12b-1 distribution and service fees, 529 administrative services fees, shareholder servicing fees, and other payments to financial intermediaries that sell Fund shares as described in Appendix D of this Part II.

INVESTMENT STRATEGIES, RISKS AND RESTRICTIONS

Set forth in Appendix E of this Part II is a description of investment strategies which the MFS Funds may generally use in pursuing their investment objectives and investment policies to the extent such strategies are consistent with their investment objectives and investment policies, and a description of the risks associated with these investment strategies. Set forth in Appendix F of this Part II is a description of investment restrictions to which the Fund is subject.

NET INCOME AND DISTRIBUTIONS

Money Market Funds

The net income attributable to each MFS Fund that is a money market fund is determined each day during which the New York Stock Exchange is open for trading (see “Determination of Net Asset Value” below for a list of days that the Exchange is closed).

For this purpose, the net income attributable to shares of a money market fund (from the time of the immediately preceding determination thereof) shall consist of (i) all interest income accrued on the portfolio assets of the money market fund less (ii) all actual and accrued expenses of the money market fund determined in accordance with generally accepted accounting principles. Interest income shall include discount earned (including both original issue and market discount) on discount paper accrued ratably to the date of maturity.

Since the net income is declared as a dividend each time the net income is determined, the net asset value per share (i.e., the value of the net assets of the money market fund divided by the number of shares outstanding) is expected to remain at $1.00 per share immediately after each such determination and dividend declaration. Any increase in the value of a shareholder’s investment, representing the reinvestment of dividend income, is reflected by an increase in the number of shares in the shareholder’s account.

13

Table of Contents

It is expected that the shares of the money market fund will have a positive net income at the time of each determination thereof. If for any reason the net income determined at any time is a negative amount, which could occur, for instance, upon default by an issuer of a portfolio security, the money market fund would first offset the negative amount with respect to each shareholder account from the dividends declared during the month with respect to each such account. If and to the extent that such negative amount exceeds such declared dividends at the end of the month (or during the month in the case of an account liquidated in its entirety), the money market fund could reduce the number of its outstanding shares by treating each shareholder of the money market fund as having contributed to its capital that number of full and fractional shares of the money market fund in the account of such shareholder which represents its proportion of such excess. Each shareholder of the money market fund will be deemed to have agreed to such contribution in these circumstances by his or her investment in the money market fund. This procedure would permit the net asset value per share of the money market fund to be maintained at a constant $1.00 per share.

In addition, the money market funds intend to distribute net realized short- and long-term capital gains, if any, at least annually.

Other Funds

Each MFS Fund other than the MFS money market funds intends to distribute to its shareholders all or substantially all of its net investment income. The net investment income of these Funds consists of non-capital gain income less expenses. In addition, these Funds intend to distribute net realized short- and long-term capital gains, if any, at least annually. Shareholders will be informed of the tax consequences of such distributions, including whether any portion represents a return of capital, after the end of each calendar year.

TAX CONSIDERATIONS

The following discussion is a brief summary of some of the important U.S. federal (and, where noted, state) income tax consequences affecting the Fund and its shareholders. The discussion is very general, and therefore prospective investors are urged to consult their tax advisers about the impact an investment in the Fund may have on their own tax situations.

Tax Treatment of the Fund

Federal Taxes — The Fund (even if it is a Fund in a Trust with multiple series) is treated as a separate entity for federal income tax purposes under the Internal Revenue Code of 1986, as amended (the “Code”). The Fund has elected (or in the case of a new Fund, intends to elect) to be, and intends to qualify to be treated each year as, a “regulated investment company” under Subchapter M of the Code.

14

Table of Contents

In order to qualify for the special tax treatment accorded regulated investment companies and their shareholders, the Fund must, among other things:

(a) derive at least 90% of its gross income for each taxable year from (i) dividends, interest, payments with respect to certain securities loans, and gains from the sale or other disposition of stock, securities or foreign currencies, or other income (including but not limited to gains from options, futures, or forward contracts) derived with respect to its business of investing in such stock, securities, or currencies and (ii) net income derived from interests in “qualified publicly traded partnerships” (as defined below);

(b) diversify its holdings so that, at the end of each quarter of the Fund’s taxable year, (i) at least 50% of the market value of the Fund’s total assets is represented by cash and cash items, U.S. Government securities, securities of other regulated investment companies, and other securities limited in respect of any one issuer to a value not greater than 5% of the value of the Fund’s total assets and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of the Fund’s total assets is invested (x) in the securities (other than those of the U.S. Government or other regulated investment companies) of any one issuer or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses or (y) in the securities of one or more qualified publicly traded partnerships (as defined below); and

(c) distribute with respect to each taxable year at least 90% of the sum of its investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid; generally, taxable ordinary income and the excess, if any, of the net short-term capital gains over net long-term capital losses) and net tax-exempt interest income, for such year.

In general, for purposes of the 90% income requirement described in paragraph (a) above, income derived from a partnership will be treated as qualifying income only to the extent such income is attributable to items of income of the partnership which would be qualifying income if realized directly by the regulated investment company. However, 100% of the net income derived from an interest in a “qualified publicly traded partnership” (which is defined as any partnership (x) whose interests are traded on an established securities market or whose interests are readily traded on a secondary market or the substantial equivalent thereof, (y) that derives at least 90% of its income from passive income sources defined in Code section 7704(d), and (z) that derives less than 90% of its income from the qualifying income described in paragraph (a)(i) above) will be treated as qualifying income. In addition, although in general the passive loss rules of the Code do not apply to regulated investment companies, such rules do apply to a regulated investment company with respect to items

15

Table of Contents

attributable to an interest in a qualified publicly traded partnership. In the case of the Fund’s investment in loan participations, the Fund shall treat both the entity from whom the loan participation is acquired and the borrower as an issuer for the purposes of meeting the diversification requirement described in paragraph (b). Finally, for purposes of paragraph (b) above, the term “outstanding voting securities of such issuer” will include the equity securities of a qualified publicly traded partnership.

As a regulated investment company, the Fund will not be subject to any U.S. federal income or excise taxes on its net investment income and net realized capital gains that it distributes to shareholders in accordance with the timing requirements imposed by the Code. The Fund’s foreign-source income, if any, may be subject to foreign withholding taxes, which could decrease the Fund’s return on the underlying investments. If the Fund failed to qualify as a “regulated investment company” in any year, it would incur a regular federal corporate income tax on all of its taxable income, whether or not distributed, and Fund distributions, including any distributions of net tax-exempt income and net long-term capital gains, would generally be taxable as dividend income to the shareholders. Some portions of such distributions may be eligible for the dividends received deduction in case of corporate shareholders and may be eligible to be treated as “qualified dividend income” in the case of shareholders taxed as individuals. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

If the Fund fails to distribute in a calendar year substantially all (at least 98%) of its ordinary income for such year and substantially all (at least 98%) of its capital gain net income for the one-year period ending October 31 (or later if the Fund is permitted so to elect and so elects), plus any retained amount from the prior year, the Fund will be subject to a non-deductible 4% excise tax on the undistributed amounts. A dividend paid to shareholders by the Fund in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November, or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax, although there can be no assurance that it will be able to do so.

Massachusetts Taxes — As long as it qualifies as a regulated investment company under the Code, the Fund will not be required to pay Massachusetts income or excise taxes.

Taxation of Shareholders

Tax Treatment of Distributions — Subject to the special rules discussed below for Municipal Funds, shareholders of the Fund normally will have to pay federal income tax and any state or local income taxes on the dividends and “Capital Gain Dividends” (as defined below) they receive from the Fund. Except as described below, any distributions from ordinary income or from net short-term capital gains are taxable to shareholders as ordinary income for federal income tax purposes whether paid in cash or reinvested in additional shares.

For taxable years beginning before January 1, 2011, “qualified dividend income” received by an individual will be taxed at the rates applicable to long-term capital gains. In order for some portion of the Fund’s dividends to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend-paying stocks in its portfolio and the Fund shareholder must meet holding period and other requirements with respect to the Fund’s shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. Payments in lieu of dividends, such as payments pursuant to securities lending arrangements, also do not qualify to be treated as qualified dividend income.

In general, a distribution of investment income designated by the Fund as derived from qualified dividend income will be treated as qualified dividend income by a shareholder taxed as an individual provided the shareholder meets the holding period and other requirements described above with respect to the Fund’s shares. In any event, if the qualified dividend income received by the Fund during any taxable year is 95% or more of its gross income for that taxable year, then 100% of the Fund’s dividends (other than Capital Gain Dividends), will be eligible to be treated as qualified dividend income. For this purpose, in the case of a sale or other disposition of the Fund of stock or securities, the only gain included in the term “gross income” is the excess of net short-term capital gain from such sales or dispositions over the net long-term capital loss from such sales or dispositions.

17

Table of Contents

Properly designated distributions of net capital gain (i.e., the excess of net long-term capital gain over the net short-term capital loss) (“Capital Gains Dividends”), whether paid in cash or reinvested in additional shares, are taxable to shareholders as long-term capital gains for federal income tax purposes without regard to the length of time the shareholders have held their shares.

Long-term capital gain rates applicable to individuals have been temporarily reduced – in general, to 15% with lower rates applying to taxpayers in the 10% and 15% rate brackets – for taxable years beginning before January 1, 2011.

Any Fund dividend that is declared in October, November, or December of any calendar year, payable to shareholders of record in such a month and paid during the following January, will be treated as if received by the shareholders on December 31 of the year in which the dividend is declared. The Fund will notify shareholders regarding the federal tax status of its distributions after the end of each calendar year.

Any Fund distribution, other than dividends that are declared by the Fund on a daily basis, will have the effect of reducing the per share net asset value of Fund shares by the amount of the distribution. If you buy shares when a Fund has unrealized or realized but not yet distributed ordinary income or capital gains, you will pay full price for the shares and then receive a portion back as a taxable distribution even though such distribution may economically represent a return of your investment.

Capital Loss Carryforwards— Distributions from capital gains are generally made after applying any available capital loss carryforwards. The amounts and expiration dates of any capital loss carryforwards available to the Fund are shown in the notes to the financial statements for the Fund.

Dividends-Received Deduction— A portion of the dividends the Fund receives from U.S. corporations is normally eligible for the dividends-received deduction for corporate shareholders if the shareholder otherwise qualifies for that deduction with respect to its holding of Fund shares. Availability of the deduction for particular corporate shareholders is subject to certain limitations, and deducted amounts may be subject to the alternative minimum tax or result in certain basis adjustments.

Disposition of Shares— In general, any gain or loss realized upon a disposition of Fund shares by a shareholder that holds such shares as a capital asset will be treated as a long-term capital gain or loss if the shares have been held for more than 12 months and otherwise as a short-term capital gain or loss. However, any loss realized upon a disposition of Fund shares held for six months or less will be treated as a long-term capital loss to the extent of any Capital Gain Dividends received (or deemed received) by the shareholder with respect to those shares. All or a portion of any loss realized upon a taxable disposition of Fund shares will be disallowed if other substantially identical shares of the Fund are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

18

Table of Contents

Shares Purchased Through Tax-Qualified Plans — Distributions by the Fund to retirement plans that qualify for tax-exempt treatment under federal income tax laws will not be taxable. Special tax rules apply to investments through such plans. You should consult your tax adviser to determine the suitability of the Fund as an investment through such a plan and the tax treatment of distributions (including distributions of amounts attributable to an investment in the Fund) from such a plan.

U.S. Taxation of Non-U.S. Persons — Capital Gain Dividends and exempt-interest dividends, if any, will not be subject to withholding of federal income tax. However, distributions properly designated as exempt-interest dividends may be subject to backup withholding, as discussed below. In general, dividends other than Capital Gain Dividends and exempt-interest dividends, if any, paid by the Fund to a shareholder that is not a “U.S. person” within the meaning of the Code (such shareholder, a “Non-U.S. Person”) are subject to withholding of U.S federal income tax at a rate of 30% (or lower applicable treaty rate) even if they are derived from income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a Non-U.S. Person directly, would not be subject to withholding. However, effective for taxable years of the Fund beginning after December 31, 2004, and before January 1, 2008, the Fund will not be required to withhold any amounts with respect to (i) distributions (other than distributions to a Non-U.S. Person (w) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (x) to the extent that the dividend is attributable to certain interest on an obligation if the Non-U.S. Person is the issuer or is a 10% shareholder of the issuer, (y) that is within certain foreign countries that have inadequate information exchange with the United States, or (z) to the extent the dividend is attributable to interest paid by a person that is a related person of the Non-U.S. Person and the Non-U.S. Person is a controlled foreign corporation) from U.S.-source interest income that would not be subject to U.S. federal income tax if earned directly by an individual Non-U.S. Person (an “interest-related dividend”), and (ii) distributions (other than (a) distributions to an individual Non-U.S. Person who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution and (b) distributions subject to special rules regarding the disposition of U.S. real property interests as described below) of net short-term capital gains in excess of net long-term capital losses (a “short-term capital gain dividend”), in each such case to the extent such distributions are properly designated by the Fund. Depending on the circumstances, the Fund may make such designations with respect to all, some or none of its potentially eligible dividends and/or treat such dividends, in whole or in part, as ineligible for this exemption for withholding. Pending legislation would extend the exemption from withholding for interest-related and short-term capital gain dividends. As of the date of this SAI, it is unclear whether the legislation will be enacted. The Fund does not currently intend to, but may in certain circumstances, designate

19

Table of Contents

distributions as interest-related dividends or as short-term capital gain dividends except with respect to shares of Research Bond Fund J . In order to qualify for this exemption from withholding, a foreign person will need to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN or substitute Form). In the case of shares held through an intermediary, the intermediary may withhold even if the Fund makes a designation with respect to a payment. Foreign persons should contact their intermediaries with respect to the application of these rules to their accounts.

If a beneficial holder who is a Non-U.S. Person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Special rules apply to distributions to foreign shareholders from a Fund that is either a “U.S. real property holding corporation” (“USRPHC”) or would be a USRPHC but for the operation of certain exceptions to the definition thereof. Additionally, special rules apply to the sale of shares in a Fund that is a USRPHC. Very generally, a USRPHC is a domestic corporation that holds U.S. real property interests (“USRPIs”) – USRPIs are defined very generally as any interest in U.S. real property or any equity interest in a USRPHC – the fair market value of which equals or exceeds 50% of the sum of the fair market values of the corporation’s USRPIs, interests in real property located outside the United States and other assets. A Fund that holds (directly or indirectly) significant interests in REITs may be a USRPHC. The special rules discussed below will also apply to distributions from a Fund that would be a USRPHC absent exclusions from USRPI treatment for interests in domestically controlled REITs and not-greater-than-5% interests in publicly traded classes of stock in REITs.

In the case of a Fund that would be a USRPHC but for the exceptions from the definition of USRPIs (described above), amounts the Fund receives from REITs derived from gains realized from USRPIs will retain their character as gains realized from USRPIs in the hands of the Fund’s foreign shareholders. Under current law, any direct USPRI gain the Fund recognizes does not retain its character as USPRI gain in the hands of foreign shareholders of the Fund, although this may change if certain legislation is enacted. In the hands of a foreign shareholder that holds (or has held in the prior year) more than a 5% interest in the Fund, such amounts will be treated as gains “effectively connected” with the conduct of a “U.S. trade or business,” and subject to tax at graduated rates. Moreover, such shareholders will be required to file a U.S. income tax return for the year in which the gain was recognized and the Fund will be required to withhold 35% of the amount of such distribution. In the case of all other foreign shareholders (i.e., those with a 5% or smaller interest in the Fund), the USRPI distribution will be treated as ordinary income (regardless

20

Table of Contents

of any designation by the Fund that such distribution is a short-term gain or a Capital Gain Dividend), and the Fund must withhold 30% (or a lower applicable treaty rate) of the amount of the distribution paid to such foreign shareholder. Foreign shareholders of such Funds are also subject to “wash sale” rules to prevent the avoidance of the tax-filing and -payment obligations discussed above through the sale and repurchase of Fund shares.

In addition, a Fund that is a USRPHC must withhold 10% of the amount realized in a redemption by a greater-than-5% foreign shareholder, and that shareholder must file a U.S. income tax return for the year of the disposition of the USRPI and pay any additional tax due on the gain. Before January 1, 2008, no withholding was generally required with respect to amounts paid in redemption of shares of a Fund that was a USRPHC and was also “domestically controlled.” It is possible that Congress will extend this exemption from withholding to the current or future years, but no such legislation has been enacted as of the date of this SAI.

Under U.S. federal tax law, a beneficial holder of shares who is a Non-U.S. Person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met, or (iii) the shares are USRPIs or the Capital Gain Dividends are USRPI Distributions.

Foreign investors in the Fund should consult their tax advisers with respect to the potential application of the these rules.

Backup Withholding — The Fund is also required in certain circumstances to apply backup withholding on taxable dividends, including Capital Gain Dividends, redemption proceeds (except for redemptions by money market funds), and certain other payments that are paid to any non-corporate shareholder (including a Non-U.S. Person) who does not furnish to the Fund certain information and certifications or who is otherwise subject to backup withholding. The backup withholding rate is currently 28% and will be 31% for amounts paid after December 31, 2010, unless Congress enacts tax legislation providing otherwise. Shareholders who are neither citizens nor residents of the United States may qualify for exemption from backup withholding and should consult their tax advisors in the regard. The back-up withholding rules may also apply to distributions that are properly designated as exempt-interest dividends.

Foreign Income Taxation of a Foreign Investor — Distributions received from the Fund by a foreign investor may also be subject to tax under the laws of the investor’s own jurisdiction.

21

Table of Contents

State and Local Income Taxes: U.S. Government Securities — Dividends paid by the Fund that are derived from interest on obligations of the U.S. Government and certain of its agencies and instrumentalities (but generally not distributions of capital gains realized upon the disposition of such obligations) may be exempt from state and local income taxes. The Fund generally intends to advise shareholders of the extent, if any, to which its dividends consist of such interest. Shareholders are urged to consult their tax advisers regarding the possible exclusion of such portion of their dividends for state and local income tax purposes.

Certain Investments — Any investment in zero coupon bonds, deferred interest bonds, payment-in-kind bonds, certain inflation-adjusted debt instruments, certain stripped securities, and certain securities purchased at a market discount (including certain high yield debt obligations) will cause the Fund to recognize income prior to the receipt of cash payments with respect to those securities. To distribute this income and avoid a tax on the Fund, the Fund may be required to liquidate portfolio securities that it might otherwise have continued to hold, potentially resulting in additional taxable gain or loss to the Fund. In the event the Fund realizes net capital gains from such transactions, its shareholders may receive a larger capital gain distribution than they would in the absence of such transactions.Such investments may also affect the character of income recognized by the Fund.

Investments in debt obligations that are at risk of or in default present special tax issues for the Fund. Tax rules are not entirely clear about issues such as when the Fund may cease to accrue interest, original issue discount or market discount, when and to what extent deductions may be taken for bad debts or worthless securities and how payments received on obligations in default should be allocated between principal and income. These and other related issues will be addressed by the Fund when, as and if it invests in such securities, in order to seek to ensure that it distributes sufficient income to preserve its status as a regulated investment company and does not become subject to U.S. federal income or excise tax.

Mortgage Pooling Vehicles — Under a notice issued by the IRS in October 2006 and Treasury regulations that have yet to be issued but may apply retroactively, a portion of a Fund’s income (including income allocated to the Fund from a REIT or other pass-through entity) that is attributable to a residual interest in a real estate mortgage investment conduit (“REMIC”) or an equity interest in a taxable mortgage pool (“TMP”) (referred to in the Code as an “excess inclusion”) will be subject to federal income tax in all events. This notice also provides, and the regulations are expected to provide, that excess inclusion income of a regulated investment company will be allocated to shareholders of the regulated investment company in proportion to the dividends received by such shareholders, with the same consequences as if the shareholders held the related residual interest directly. As a result, a Fund investing in such interests may not be a suitable investment for charitable remainder trusts (“CRTs”) (see below).

22

Table of Contents

In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income (“UBTI”) to entities (including a qualified pension plan, an individual retirement account, a 401(k) plan, a Keogh plan or other tax-exempt entity) subject to tax on UBTI, thereby potentially requiring such an entity that is allocated excess inclusion income, and otherwise might not be required to file a tax return, to file a tax return and pay tax on such income, and (iii) in the case of a Non-U.S. Person, will not qualify for any reduction in U.S. federal withholding tax. In addition, if at any time during any taxable year a “disqualified organization” (as defined in the Code generally to mean governmental and certain other tax-exempt organizations) is a record holder of a share in the Fund, then the Fund will be subject to a tax equal to that portion of its excess inclusion income for the taxable year that is allocable to the disqualified organization, multiplied by the highest federal income tax rate imposed on corporations. To the extent permitted under the 1940 Act, the Fund may elect to specially allocate any such tax to the applicable disqualified organization, and thus reduce such shareholder’s distributions for the year by the amount of the tax that relates to such shareholder’s interest in the Fund. The Fund has not yet determined whether such an election will be made.

Under current law, the Fund serves to “block” the attribution of UBTI to tax-exempt shareholders. Notwithstanding this “blocking” effect, a tax-exempt shareholder could realize UBTI by virtue of its investment in the Fund if shares in the Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Code Section 514(b).

In addition, special tax consequences apply to CRTs that invest in regulated investment companies that invest directly or indirectly in residual interests in REMICs or equity interests in TMPs. Under legislation enacted in December 2006, a charitable remainder trust, as defined in section 664 of the Code, that realizes UBTI for a taxable year must pay an excise tax annually of an amount equal to such UBTI. Under IRS guidance issued in November 2006, a CRT that invests in the Fund should not recognize UBTI as a result of the Fund recognizing “excess inclusion income.” Rather, as described above, the Fund will be subject to a tax on that portion of its “excess inclusion income” that is allocable to the CRT (and any other disqualified organizations) for the taxable year at the highest federal corporate income tax rate. The extent to which the IRS guidance remains applicable to CRTs in light of the December 2006 CRT legislation is unclear. CRTs are urged to consult their tax advisors concerning the consequences of investing in the Fund.

Derivatives, Hedging, and Related Transactions — The Fund’s transactions in options, futures contracts, forward contracts, short sales, swaps, foreign currencies, and related transactions will be subject to special tax rules (which may include mark-to-market, constructive sale, notional principal contract, straddle, and wash sale rules) that may affect the amount, timing, and character of Fund income and distributions to shareholders. For example, certain positions held by the Fund may be “Section 1256 contracts.” On the last business day of each taxable year, these positions will be marked to market (i.e., treated as if closed out on that day), and any gain or loss associated with such positions will be treated as 60% long-term and 40% short-term capital gain or loss (except that foreign currency gain or loss arising from Section 1256 contracts may be ordinary in character). Certain positions held by the Fund that substantially diminish its risk of loss with respect to other positions in its portfolio may constitute “straddles” for federal income tax purposes. The straddle rules may cause deferral of Fund losses, adjustments in the holding periods of Fund securities, and conversion of short-term capital losses into long-term capital losses and long-term capital gains into short-term capital gains. Certain tax elections exist for straddles that may alter the effects with respect to those investments. These rules can cause the Fund to recognize income for tax purposes prior to the receipt of cash payments with respect to the underlying investments; in order to distribute this income and avoid a tax on the Fund, the Fund may be required to liquidate portfolio securities that it might otherwise have continued to hold, potentially resulting in additional taxable gain or loss to the Fund and additional taxable distributions to shareholders. The Fund intends to limit its activities in options, futures contracts, forward contracts, short sales, and swaps and related transactions to the extent necessary to meet the requirements for qualification and treatment as a regulated investment company under Subchapter M of the Code.

Certain hedging activities (including its transactions, if any, in foreign currencies or foreign currency-denominated instruments) are likely to produce a difference between its book income and its taxable income. If the Fund’s book income exceeds its taxable income, the distribution (if any) of such excess generally will be treated as (i) a dividend to the extent of the Fund’s remaining earnings and profits (including earnings and profits arising from any tax-exempt income), (ii) thereafter, as a return of capital to the extent of the recipient’s basis in its shares, and (iii) thereafter, as gain from the sale or exchange of a capital asset. If the Fund’s book income is less than the sum of its taxable income and net tax-exempt income (if any), the Fund could be required to make distributions exceeding book income to qualify as a regulated investment company that is accorded special tax treatment.

Foreign Investments and Foreign Currencies — Special tax considerations apply with respect to any foreign investments by the Fund. Foreign exchange gains and losses realized by the Fund may be treated as ordinary income and loss. The Code grants the Secretary of Treasury the right to issue tax regulations that would exclude income and gains from direct investments in foreign currencies from treatment as qualifying income for purposes of the qualifying income test

24

Table of Contents

for regulated investment companies described earlier in cases where the foreign currency gains are not directly related to the company’s principal business of investing in stocks or securities (or options or futures with respect to stocks or securities). If the Secretary of the Treasury were to issue such regulations, a Fund may need to change its investment practices in order to qualify as a regulated investment company. In addition, there is a remote possibility that such regulations may be applied retroactively. Use of foreign currencies for non-hedging purposes and investment by the Fund in certain “passive foreign investment companies” may be limited in order to avoid a tax on the Fund. The Fund may elect to mark to market certain investments in “passive foreign investment companies” on the last day of each year. This election may cause the Fund to recognize income prior to the receipt of cash payments with respect to those investments; in order to distribute this income and avoid a tax on the Fund, the Fund may be required to liquidate portfolio securities that it might otherwise have continued to hold, potentially resulting in additional taxable gain or loss to the Fund and additional taxable distributions to shareholders.

Foreign Income Taxes — Investment income received by the Fund and gains with respect to foreign securities may be subject to foreign income taxes withheld at the source. The United States has entered into tax treaties with many foreign countries that may entitle the Fund to a reduced rate of tax or an exemption from tax on such income; the Fund intends to qualify for treaty reduced rates where available. It is not possible, however, to determine the Fund’s effective rate of foreign tax in advance, since the amount of the Fund’s assets to be invested within various countries is not known.

If more than 50% of the total assets of a Fund are represented by direct investments in foreign stock and securities at the close of its taxable year, the Fund may elect to “pass through” to its shareholders foreign income taxes paid by it. If the Fund so elects, shareholders will be required to treat as part of the amounts distributed to them by the Fund their pro rata portions of qualified taxes paid by the Fund to foreign countries in respect of foreign securities that the Fund has held for at least the minimum period specified in the Code and thus include those portions in their gross income for federal income tax purposes. Therefore, shareholders my in turn claim a credit or deduction on their income tax returns for their pro rata portions of such qualified taxes. Shareholders who do not itemize deductions would (subject to such limitations) be able to claim a credit but not a deduction. No deduction will be permitted to individuals in computing their alternative minimum tax liability. If the Fund is not eligible, or does not elect, to “pass through” to its shareholders foreign income taxes it has paid, shareholders will not be able to claim any deduction or credit for any part of the foreign taxes paid by the Fund. In addition, investments in certain foreign securities (including fixed income securities and derivatives) denominated in foreign currencies may increase or accelerate the Fund’s recognition of ordinary income and may affect the timing, amount, or character of the Fund’s distributions.

Tax Shelter Reporting — Under Treasury regulations, if a shareholder recognizes a loss with respect to the Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the Internal Revenue Service a disclosure statement on Form 8886. Shareholders should consult their tax advisers to determine the applicability of these regulations in light of their individual circumstances.

Underlying Funds — If the Fund invests all of its assets in shares of underlying Funds, its distributable income and gains will normally consist entirely of distributions from the underlying Funds’ income and gains and gains and losses on the dispositions of shares of underlying Funds. To the extent that an underlying Fund realizes net losses on its investments for a given taxable year, the Fund will not be able to recognize its share of those losses (so as to offset distributions of net income or capital gains from other underlying Funds) until it disposes of shares of the underlying Fund. Moreover, even when the Fund does make such a disposition, a portion of its loss may be recognized as a long-term capital loss, which will not be treated as favorably for federal income tax purposes as a short-term capital loss or an ordinary deduction. In particular, the Fund will not be able to offset any capital losses from its dispositions of underlying Fund shares against its ordinary income, which includes distributions of any net short-term capital gains realized by an underlying Fund. In addition, in certain circumstances, the “wash sale” rules under Section 1091 of the Code may apply to a Fund’s sales of underlying Fund shares that have generated losses. A wash sale occurs if shares of an underlying Fund are sold by the Fund at a loss and the Fund acquires additional shares of that same underlying Fund thirty days before or after the date of the sale. The wash sale rules could defer losses of the Fund on sales of underlying Fund shares (to the extent such sales are wash sales) for extended (and, in certain cases, potentially indefinite) periods of time. As a result of the foregoing rules, and certain other special rules, it is possible that the amounts of net investment income and net capital gains that the Fund will be required to distribute to shareholders will be greater than such amounts would have been had the Fund invested directly in the securities held by the underlying Funds, rather than investing in shares of the underlying Funds. For similar reasons, the character of distributions from a Fund (e.g., capital gains as compared to ordinary income, eligibility for the dividends-received deduction, etc.) will not necessarily be the same as it would have been had the Fund invested directly in the securities held by the underlying Funds.

If the Fund received dividends from an underlying Fund that qualifies as a regulated investment company, and the underlying Fund designates such dividends as “qualified dividend income,” then the Fund is permitted in turn to designate a portion of its distributions as “qualified dividend income” as well, provided the Fund meets holding period and other requirements with respect to shares of the underlying Fund.

26

Table of Contents

Depending on the Fund’s percentage ownership in an underlying Fund before and after a redemption of shares of such underlying Fund, such a redemption may cause the Fund to be treated as receiving a dividend on the full amount of the distribution instead of receiving capital gain income on the shares of the underlying Fund. This would be the case where the Fund holds a significant interest in an underlying Fund and redeems only a small portion of such interest. It is possible that such a dividend will qualify as “qualified dividend income;” otherwise, it will be taxable as ordinary income.

The fact that a Fund achieves its investment objectives by investing in underlying Funds will generally not adversely affect the Fund’s ability to pass on to foreign shareholders the full benefit of the interest-related dividends and short-term capital gain dividends that it receives from its underlying investments in the Funds, except possibly to the extent that (1) interest-related dividends received by the Fund are offset by deductions allocable to the Fund’s qualified interest income or (2) short-term capital gain dividends received by the Fund are offset by the Fund’s net short- or long-term capital losses, in which case the amount of a distribution from the Fund to a foreign shareholder that is properly designated as either an interest-related dividend or a short-term capital gain dividend, respectively, may be less than the amount that such shareholder would have received had they invested directly in the underlying Funds. Furthermore, if the Fund is a QIE and invests in an underlying Fund that is a QIE, a distribution to a foreign shareholder that is attributable to a USRPI Distribution received by the Fund will retain its character as a USRPI Distribution when passed through to the foreign shareholder regardless of the Fund’s percentage ownership of the underlying Fund.

Under the current law, a Fund of Funds cannot pass through to shareholders foreign tax credits borne in respect of foreign securities income earned by an underlying Fund. A Fund is permitted to elect to pass through to its shareholders foreign income taxes it pays only if it directly holds more than 50% of its assets in foreign stock and securities at the close of its taxable year. Foreign securities held indirectly through an underlying Fund do not contribute to this 50% threshold.

Special Rules for Municipal Fund Distributions

The following special rules apply to shareholders of Funds whose objective is to invest primarily in obligations that pay interest that is exempt from federal income tax (“Municipal Funds”).

Tax-Exempt Distributions — The portion of a Municipal Fund’s distributions of net investment income that is attributable to interest from tax-exempt securities will be designated by the Fund as an “exempt-interest dividend” under the Code and will generally be exempt from federal income tax in the hands of shareholders so long as at least 50% of the total value of the Fund’s assets consists of tax-exempt securities at the close of each quarter of the Fund’s

27

Table of Contents

taxable year. Distributions of tax-exempt interest earned from certain securities may, however, be treated as an item of tax preference for shareholders under the federal alternative minimum tax, and all exempt-interest dividends will increase a corporate shareholder’s alternative minimum tax. Except when the Fund provides actual monthly percentage breakdowns, the percentage of income designated as tax-exempt will be applied uniformly to all distributions by the Fund of net investment income made during each fiscal year of the Fund and may differ from the percentage of distributions consisting of tax-exempt interest in any particular month. Shareholders are required to report exempt-interest dividends received from the Fund on their federal income tax returns.

Taxable Distributions — A Municipal Fund may also earn some income that is taxable as ordinary income (including interest from any obligations that lose their federal tax exemption, proceeds from the disposition of certain market discount bonds, and income received in lieu of tax-exempt interest with respect to securities on loan) and may recognize capital gains and losses as a result of the disposition of securities and from certain options and futures transactions. Shareholders normally will have to pay federal income tax on the non-exempt interest dividends and capital gain distributions they receive from the Fund, whether paid in cash or reinvested in additional shares. However, such Funds do not expect that the non-tax-exempt portion of their net investment income, if any, will be substantial. Because Municipal Funds expect to earn primarily tax-exempt interest income, it is expected that dividends from such Funds will not qualify for the dividends-received deduction for corporations and will not be treated as “qualified dividend income” taxable to non-corporate shareholders at reduced rates.

Consequences of Distributions by a Municipal Fund: Effect of Accrued Tax-Exempt Income — Shareholders redeeming shares after tax-exempt income has been accrued but not yet declared as a dividend should be aware that a portion of the proceeds realized upon redemption of the shares will reflect the existence of such accrued tax-exempt income and that this portion may be subject to tax as a capital gain even though it would have been tax-exempt had it been declared as a dividend prior to the redemption. For this reason, if a shareholder wishes to redeem shares of a Municipal Fund that does not declare dividends on a daily basis, the shareholder may wish to consider whether he or she could obtain a better tax result by redeeming immediately after the Fund declares dividends representing substantially all the ordinary income (including tax-exempt income) accrued for that period.

Certain Additional Information for Municipal Fund Shareholders — Interest on indebtedness incurred by shareholders to purchase or carry Municipal Fund shares will not be deductible for federal income tax purposes. Exempt-interest dividends are taken into account in calculating the amount of social security and railroad retirement benefits that may be subject to federal income tax. You should consult your tax adviser to determine what effect, if any, an investment

28

Table of Contents

in a Fund may have on the federal taxation of your benefits. Entities or persons who are “substantial users” (or persons related to “substantial users”) of facilities financed by private activity bonds should consult their tax advisers before purchasing Fund shares.

Consequences of Redeeming Shares — Any loss realized on a redemption of Municipal Fund shares held for six months or less will be disallowed to the extent of any exempt-interest dividends received with respect to those shares. To the extent not disallowed, any such loss will be treated as a long-term capital loss to the extent of any distributions of long-term capital gain received (or deemed received) with respect to those shares.

State and Local Income Taxes: Municipal Obligations — The exemption of exempt-interest dividends for federal income tax purposes does not necessarily result in exemption under the income tax laws of any state or local taxing authority. Some states do exempt from tax that portion of an exempt interest dividend that represents interest received by a regulated investment company on its holdings of securities issued by that state and its political subdivisions and instrumentalities. Therefore, the Fund will report annually to its shareholders the percentage of interest income earned by it during the preceding year on Municipal Bonds and will indicate, on a state-by-state basis only, the source of such income.

Special Considerations for 529 Share Classes

The following special consideration applies specifically to the ownership of a Fund’ 529 share classes through a tuition program that qualifies under Section 529 of the Code.

The 529 share classes are an investment option under one or more tuition programs designed to qualify under Section 529 of the Code so that earnings on investments are not subject to federal income tax (to either a contributor to the tuition program or a designated beneficiary) until the earnings are withdrawn. Withdrawals of earnings that are used to pay “qualified higher education expenses” are tax-free for federal income tax purposes. State and local taxes may still apply. These tax benefits are not available to 529 shares that are not owned through a qualifying Section 529 tuition program.

Withdrawals of earnings that are not used for the designated beneficiary’s qualified higher education expenses generally are subject not only to federal income tax but also to a 10% penalty tax unless such amounts are transferred within sixty (60) days to another tuition program for the same designated beneficiary (only one such transfer may be made in any twelve (12) month period) or another designated beneficiary who is a member of the family of the designated beneficiary with respect to which the distribution was made and certain other conditions are satisfied. The 10% penalty tax will not apply to withdrawals made under certain circumstances, including certain withdrawals

29

Table of Contents

made after the designated beneficiary dies, becomes disabled, or receives a scholarship or other tax-free payment for educational expenses that does not exceed the amount of the distribution. Withdrawals attributable to contributions to the tuition program (including the portion of any rollover from another tuition program that is attributable to contributions to that program) are not subject to tax.

PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS

For the purposes of this section, all references to the “Adviser” shall include Sun Capital with respect to the portion of the MFS Diversified Income Fund for which Sun Capital provides investment advisory services, UBS with respect to the portion of the MFS Diversified Target Return Fund for which UBS provides investment advisory services, and Valley Forge with respect to the MFS Sector Rotational Fund.

Specific decisions to purchase or sell securities for the Funds are made by persons affiliated with the Adviser. Any such person may serve other clients of the Adviser or any subsidiary of the Adviser in a similar capacity.

In connection with the selection of broker/dealers and the placing of Fund portfolio transactions, the Adviser seeks to achieve for the Funds the best overall price and execution available from responsible brokerage firms, taking account of all factors it deems relevant, including by way of illustration: price; the size of the transaction; the nature of the market of the security; the amount of the commission; the timing and impact of the transaction taking into account market prices and trends; the reputation, experience and financial stability of the broker/dealer involved; the willingness of the broker/dealer to commit capital; the need for anonymity in the market; and the quality of services rendered by the broker/dealer in that and other transactions, including the quality of the broker/dealer’s research.

In the case of securities traded in the over-the-counter market, portfolio transactions may be effected either on an agency basis, which involves the payment of negotiated brokerage commissions to the broker/dealer, including electronic communication networks, or on a principal basis at net prices without commissions, but which include compensation to the broker/dealer in the form of a mark-up or mark-down, depending on where the Adviser believes best execution is available. In the case of securities purchased from underwriters, the cost of such securities generally includes a fixed underwriting commission or concession. From time to time, soliciting dealer fees are available to the Adviser on tender or exchange offers. Such soliciting or dealer fees are, in effect, recaptured by the Funds.

30

Table of Contents

As permitted by Section 28(e) of the Securities Exchange Act of 1934, as amended (“Section 28(e)”), the Adviser may cause the Funds to pay a broker/dealer which provides “brokerage and research services” (as defined by the Securities Exchange Act of 1934, as amended) to the Adviser an amount of commission for effecting a securities transaction for the Funds in excess of the amount other broker/dealers would have charged for the transaction if the Adviser determines in good faith that the greater commission is reasonable in relation to the value of the brokerage and research services provided by the effecting broker/dealer viewed in terms of either a particular transaction or the Adviser’s overall responsibilities to the Funds and its other clients. “Commissions,” as interpreted by the SEC, include fees paid to brokers for trades conducted on an agency basis, and certain mark-ups, markdowns, commission equivalents and other fees received by dealers in riskless principal transactions placed in the NASDAQ market.

The term “brokerage and research services” includes advice as to the value of securities, the advisability of investing in, purchasing or selling securities, and the availability of securities or purchasers or sellers of securities; furnishing analyses and reports concerning issuers, industries, securities, economic factors and trends, portfolio strategy, and the performance of accounts; and effecting securities transactions and performing functions incidental thereto (such as clearance and settlement) or required in connection therewith by applicable rules. In determining whether a service or product qualifies as “brokerage and research services,” the Adviser evaluates whether the service or product provides lawful and appropriate assistance to the Adviser in carrying out its investment decision-making responsibilities. It is often not possible to place a dollar value on the brokerage and research services the Adviser receives from brokers. The determination and evaluation of the reasonableness of the brokerage commissions paid in connection with portfolio transactions is based primarily on the professional opinions of the persons responsible for the placement and review of such transactions.

Broker/dealers may be willing to furnish statistical, research and other factual information or services (“Research”), for example, investment research reports; access to analysts; execution systems and trading analytics; reports or databases containing corporate, fundamental, and technical analyses; portfolio modeling strategies; and economic research services, such as publications, chart services, and advice from economists concerning macroeconomics information, and analytical investment information about particular corporations to the Adviser for no consideration other than brokerage or underwriting commissions. Such broker/dealers (or affiliates of such broker/dealers) may be involved from time to time in executing, clearing or settling securities transactions on behalf of the Funds (“Executing Brokers”), or may have entered into agreements with one or more Executing Brokers pursuant to which they are responsible for performing one or more functions, the performance of which has been identified by the SEC as being sufficient to constitute effecting securities transactions within the meaning of Section 28(e) as interpreted by the SEC (collectively, together with Executing Brokers, “Effecting Brokers”). In reliance on this interpretation the Adviser has entered into Commission Sharing Agreements with Executing

31

Table of Contents

Brokers which will provide for the Executing Brokers to pay a portion of the Commissions paid by the Funds for securities transactions to Effecting Brokers. In addition to effecting securities transactions on behalf of the Funds pursuant to a Commission Sharing Agreement, the Effecting Brokers will also provide Research for the benefit of the Adviser. If a government agency with regulatory authority over the affairs of the Adviser or its subsidiaries, or a court of competent jurisdiction, were to determine that an Effecting Broker is not effecting a securities transaction within the meaning of Section 28(e), the Adviser believes that such Research should be considered to be Research provided by the relevant Executing Broker and permitted by Section 28(e), provided that the relationship with such Executing Broker is otherwise consistent with the requirement for Research under Section 28(e). In such circumstances the Adviser will in effect be paying a greater commission in order to obtain third party research. The Adviser may use brokerage commissions from the Funds’ portfolio transactions to acquire Research, subject to the procedures and limitations described in this discussion.

The advisory fee paid by each of the Funds to the Adviser is not reduced as a consequence of the Adviser’s receipt of Research. To the extent the Funds’ portfolio transactions are used to obtain Research, the brokerage commissions paid by the Funds might exceed those that might otherwise be paid for execution only. The Research received may be useful and of value to the Adviser or its affiliates in serving both the Funds and other clients of the Adviser or its affiliates; accordingly, not all of the Research provided by brokers through which the Funds effect securities transactions may be used by the Adviser in connection with the Funds. The Adviser would, through the use of the Research, avoid the additional expenses that would be incurred if it attempted to develop comparable information through its own staff or if it purchased such Research with its own resources.

From time to time, the Adviser prepares a list of broker/dealer firms that have been deemed by the Adviser to provide valuable Research (“Research Firms”) as determined periodically by the Adviser’s investment staff (“Research Votes”). All trades with Research Firms will be effected in accordance with the Adviser’s obligation to seek best execution for its client accounts. The Adviser uses a research vote as a guide for allocating payments for Research to Research Firms. Payments for Research to Executing Brokers and other research providers who are registered as broker-dealers (“Broker Providers”) may occur through the use of commissions pooled pursuant to Commission Sharing Agreements (“Pooled Commissions”) or may be made pursuant to commissions paid on trades executed by a Broker Provider (“Trade Commissions”). To the extent that payments for Research to a Broker Provider are made pursuant Trade Commissions, the Adviser will reduce the amount of Pooled Commissions to be paid to that Broker Provider for its research. However, the Adviser will reduce the amount of Pooled Commissions to be paid to that Broker Provider by less than the full amount of Trade Commissions paid to that Broker Provider. The research vote is also used as a guide for allocating cash payments made by the Adviser from its own resources to Research Firms that are not Broker Providers.

32

Table of Contents

If the Adviser determines that any service or product has a mixed use (i.e., it also serves functions that do not assist the investment decision-making or trading process), the Adviser may allocate the costs of such service or product accordingly in its reasonable discretion. The Adviser will allocate brokerage commissions to Research Firms only for the portion of the service or product that the Adviser determines assists it in the investment decision-making or trading process and will pay for the remaining value of the product or service in cash.

In effecting portfolio transactions on behalf of the Funds and the Adviser’s other clients, the Adviser from time to time may instruct the broker/dealer that executes a transaction to allocate, or “step out,” a portion of such transaction to another broker/dealer. The broker/dealer to which the Adviser has “stepped out” would then settle and complete the designated portion of the transaction, and the executing broker/dealer would settle and complete the remaining portion of the transaction that has not been “stepped out.” Each broker/dealer may receive a commission or brokerage fee with respect to that portion of the transaction that it settles and completes.

In certain instances there may be securities that are suitable for the Funds’ portfolios as well as for one or more of the other clients of the Adviser or of any affiliate of the Adviser (or that the Adviser believes should no longer be held by the Funds’ portfolios or by other clients of the Adviser or any subsidiary of the Adviser). It may develop that a particular security is bought or sold for only one client even though it might be held by, or bought or sold for, other clients. Likewise, a particular security may be bought for one or more clients when one or more other clients are selling that same security. Some simultaneous transactions are inevitable when several clients receive investment advice from the same investment adviser, particularly when the same security is suitable for the investment objectives of more than one client. Transactions for each client are generally effected independently unless the Adviser determines to purchase or sell the same securities for several clients at approximately the same time. The Adviser may, but is not required to, aggregate together purchases and sales for several clients and will allocate the trades in a fair and equitable manner, across participating clients. The Adviser has adopted policies that are reasonably designed to ensure that when two or more clients are simultaneously engaged in the purchase or sale of the same security, the securities are allocated among clients in a manner believed by the Adviser to be fair and equitable to each. Among other things, these policies prohibit allocations of equity initial public offerings, equity limited offerings or fixed income new issues to, among others: (1) Private Portfolio Management accounts; (2) private funds or other accounts principally owned by the Adviser’s officers and employees or Trustees of any MFS fund which are not being offered to the public; and (3) any accounts

33

Table of Contents

owned beneficially solely by the Adviser or any direct or indirect subsidiary of the Adviser except accounts in which the Adviser or any of its direct or indirect subsidiaries is the sole beneficial owner, which generally will be allocated investment opportunities (other than with respect to equity initial public offerings, equity limited offerings or fixed income new issues) on the same basis as Funds or other clients of the Adviser when the account has been established and seeded by the Adviser or the subsidiary with a limited amount of assets either for the purpose of establishing a performance record to enable the Adviser or the subsidiary to offer the account’s investment style to unaffiliated third parties or if the account is being offered to the general public. However, these policies do not prohibit allocations to funds or other accounts owned beneficially by Sun Life of Canada (U.S.) Financial Services Holdings, Inc., or Sun Life Financial Inc., or their affiliates other than the Adviser and its direct and indirect subsidiaries.

It is recognized that in some cases this system could have a detrimental effect on the price or availability of a security as far as the Funds are concerned.

DISCLOSURE OF PORTFOLIO HOLDINGS

Each Fund has established a policy governing the disclosure of its portfolio holdings that is reasonably designed to protect the confidentiality of the Fund’s non-public portfolio holdings and prevent inappropriate selective disclosure of such holdings. The Fund’s Board of Trustees has approved this policy and will be asked to approve any material amendments to this policy. Exceptions to this policy may be authorized by MFS’ general counsel or a senior member of the MFS legal department acting under the supervision of MFS’ general counsel (an “Authorized Person”).

Neither MFS nor the Fund nor, if applicable, a sub-adviser, will receive any compensation or other consideration in connection with its disclosure of Fund portfolio holdings.

Public Disclosure of Portfolio Holdings

In addition to the public disclosure of Fund portfolio holdings through required SEC quarterly filings, a Fund may make its portfolio holdings publicly available on the MFS Web site in such scope and form and with such frequency as MFS may reasonably determine.

34

Table of Contents

The following information is generally available to you on the MFS Web site ( mfs.com ):

If a fund has substantial investments in both equity and debt instruments, the fund’s top 10 equity holdings and top 10 debt holdings will be made available. In addition, for fund’s that primarily invest in shares of the other MFS funds, all securities holdings in shares of MFS funds, the top 10 aggregated equity holdings within the underlying MFS funds, and the top 10 aggregated debt holdings within the underlying MFS funds will be made available.

Note that the Fund or MFS may suspend the posting of this information or modify the elements of this Web posting policy without notice to shareholders. Once posted, the above information will remain available on the Web site until at least the date on which the Fund files a Form N-CSR or Form N-Q for the period that includes the date as of which the Web site information is current.

Certain registered investment companies that are advised by MFS and registered investment companies that are sub-advised by MFS or its affiliates are subject to different portfolio holdings disclosure policies that may permit public disclosure of portfolio holdings information in different forms and at different times. In addition, separate account and unregistered product clients of MFS or its affiliates have same day access to their portfolio holdings, and prospective clients and their advisers have access to representative portfolio holdings. Some of these registered investment companies, sub-advised Funds, separate accounts, and unregistered products, all advised or sub-advised by MFS or its affiliates, have substantially similar, or in some cases nearly identical, portfolio holdings to certain Funds (Similarly Managed Investment Products). A Similarly Managed Investment Product is not subject to the portfolio holdings disclosure policies of the Fund to which it is similar and may disclose its similar or nearly identical portfolio holdings information in different forms and at different times than such Fund.

A Fund’s portfolio holdings are considered to be publicly disclosed: (a) upon the disclosure of the portfolio holdings in a publicly available, routine filing with the SEC that is required to include the information; (b) the day after the Fund makes such information available on its Web site (assuming that it discloses in its prospectus that such information is available on its Web site); or (c) at such additional times and on such additional basis as determined by the SEC or its staff.

Disclosure of Non-Public Portfolio Holdings

A Fund may, in certain cases, disclose to third parties its portfolio holdings which have not been made publicly available. Disclosure of non-public portfolio holdings to third parties may only be made if an Authorized Person determines that such disclosure is not impermissible under applicable law or regulation. In the case of a sub-adviser, this determination may be made by a senior member of the sub-adviser’s legal or compliance departments (a “Sub-Adviser Authorized Person”); provided, however, an Authorized Person may override such determination. In addition, the third party receiving the non-public portfolio holdings may, at the discretion of an Authorized Person, be required to agree in writing to keep the information confidential and/or agree not to trade directly or indirectly based on the information. Such agreements may not be required in circumstances such as where portfolio securities are disclosed to brokers to obtain bids/prices or in interviews with the media. MFS will use reasonable efforts to monitor a recipient’s use of non-public portfolio holdings provided under these agreements by means that may include contractual provisions, notices reminding a recipient of their obligations or other commercially reasonable means. The restrictions and obligations described in this paragraph do not apply to non-public portfolio holdings provided to MFS or its affiliates.

In addition, to the extent that an Authorized Person determines that there is a potential conflict with respect to the disclosure of information that is not publicly available between the interests of a Fund’s shareholders, on the one hand, and MFS, MFD or an affiliated person of MFS, MFD, or the Fund, on the other hand, the Authorized Person must inform MFS’ conflicts officer of such potential conflict, and MFS’ conflicts officer shall determine whether, in light of the potential conflict, disclosure is reasonable under the circumstances, and shall report such potential conflict of interest determinations to the Fund’s Independent Chief Compliance Officer and the Board of Trustees of the Fund. MFS also reports to the Board of Trustees of the Fund regarding the disclosure of information regarding the Fund that is not publicly available.

Subject to compliance with the standards set forth in the previous two paragraphs, non-public portfolio holdings may be disclosed in the following circumstances:

Employees of MFS or MFD or, if applicable, a sub-adviser, (collectively “Fund representatives”) disclose non-public portfolio holdings in connection with the day-to-day operations and management of the Fund. Full portfolio holdings are disclosed to a Fund’s custodians, independent registered accounting firm, financial printers, regulatory authorities, and stock exchanges and other listing organizations. Portfolio holdings are disclosed to a Fund’s pricing service vendors and broker/dealers when requesting bids for, or price quotations on, securities, and to other persons (including independent contractors) who provide systems or software support in connection with Fund operations, including accounting, compliance support, and pricing. Portfolio holdings may

36

Table of Contents

also be disclosed to persons assisting a Fund in the voting of proxies or in connection with litigation relating to Fund portfolio holdings. In connection with managing the Funds, MFS or, if applicable, a sub-adviser, may use analytical systems provided by third parties who may have access to Fund portfolio holdings.

Non-public portfolio holdings may be disclosed in connection with other activities, such as to participants in in-kind purchases and redemptions of Fund shares, to service providers facilitating the distribution or analysis of portfolio holdings, once the information is public, and in other circumstances not described above. All such disclosures are subject to compliance with the applicable disclosure standards.

In addition, subject to such disclosure not being impermissible under applicable law or regulation, Fund representatives may disclose Fund portfolio holdings and related information, which may be based on non-public portfolio holdings, under the following circumstances (among others):

Fund representatives may provide oral or written information (“portfolio commentary”) about a Fund, including, but not limited to, how the Fund’s investments are divided among various sectors, industries, countries, value and growth stocks, small, mid, and large-cap stocks, among stocks, bonds, currencies and cash, types of bonds, bond maturities, bond coupons, and bond credit quality ratings. This portfolio commentary may also include information on how these various weightings and factors contributed to Fund performance. Fund representatives may also express their views orally or in writing on one or more of a Fund’s portfolio holdings or may state that a Fund has recently purchased or sold one or more holdings.

Fund representatives may also provide oral or written information (“statistical information”) about various financial characteristics of a Fund or its underlying portfolio securities including, but not limited to, alpha, beta, coefficient of determination, duration, maturity, information ratio, Sharpe ratio, earnings growth, payout ratio, price/book value, projected earnings growth, return on equity, standard deviation, tracking error, weighted average quality, market capitalization, percent debt to equity, price to cash flow, dividend yield or growth, default rate, portfolio turnover, and risk and style characteristics.

The portfolio commentary and statistical information may be provided to members of the press, shareholders in the Fund, persons considering investing in the Fund, or representatives of such shareholders or potential shareholders, such as fiduciaries of a 401(k) plan or a trust and their advisers, and the content and nature of the information provided to each of these persons may differ.

Ongoing Arrangements To Make Non-Public Portfolio Holdings Available

With authorization from an Authorized Person or, as applicable, a Sub-Adviser Authorized Person, consistent with “Disclosure of Non-Public Portfolio Holdings” above, Fund representatives may disclose non-public Fund portfolio holdings to the recipients identified on Appendix G , of this SAI Part II or permit the recipients identified in Appendix G of this SAI Part II to have access to non-public Fund portfolio holdings, on an on-going basis.

This list of recipients in Appendix G of this SAI Part II is current as of February 1, 2008, and any additions, modifications, or deletions to this list that have occurred since February 1, 2008, are not reflected. The portfolio holdings of the Fund which are provided to these recipients, or to which these recipients have access, may be the Fund’s current portfolio holdings. As a condition to receiving or being provided access to non-public Fund portfolio holdings, the recipients listed in Appendix G of this SAI Part II must agree, or otherwise have an independent duty, to maintain this information in confidence.

DETERMINATION OF NET ASSET VALUE

The net asset value per share of each class of the Funds is determined each day during which the New York Stock Exchange (the “Exchange”) is open for trading. (As of the date of this SAI, the Exchange is open for trading every weekday except in an emergency and for the following holidays (or the days on which they are observed): New Year’s Day; Martin Luther King Day; Presidents’ Day; Good Friday; Memorial Day; Independence Day; Labor Day; Thanksgiving Day, and Christmas Day.) This determination is made once each day as of the close of regular trading on the Exchange (generally, 4 p.m., Eastern time) (the “valuation time”) by deducting the amount of the liabilities attributable to the class from the value of the assets attributable to the class and dividing the difference by the number of Fund shares outstanding for that class. In accordance with regulations for regulated investment companies and except for money market funds, changes in portfolio holdings and number of shares outstanding are generally reflected in a Fund’s net asset value the next business day after such change.

Money Market Funds

Money market instruments are valued at amortized cost, which approximates market value. Amortized cost involves valuing an instrument at its cost as adjusted for amortization of premium or accretion of discount rather than its current market value. Each money market fund’s use of amortized cost is subject to the Fund’s compliance with Rule 2a-7 under the Investment Company Act of 1940. The amortized cost value of an instrument can be different from the market value of an instrument.

The Board of Trustees for each money market fund has established procedures designed to stabilize its net asset value per share at $1.00 and has delegated to the Adviser the responsibility for the implementation and administration of such procedures. Under the procedures, the adviser is responsible for

monitoring and notifying the Board of Trustees of circumstances where the net asset value calculated by using market valuations may deviate from the $1.00 per share calculated using amortized cost and might result in a material dilution or other unfair result to investors or existing shareholders. Under such circumstances, the Board may take such corrective action, if any, as it deems appropriate to eliminate or reduce, to the extent reasonably practicable, any such dilution or unfair results. Such corrective action could include selling portfolio instruments prior to maturity to realize capital gains or losses; shortening average portfolio maturity; withholding dividends; calculating net asset value by using available market quotations; and such other measures as the Trustees may deem appropriate.

Non-Money Market Funds

Open-end investment companies are generally valued at their net asset value per share. The underlying investments of open-end investment companies managed by the Adviser are valued as described below.

Equity securities, including restricted equity securities, are generally valued at the last sale or official closing price as provided by an independent pricing service on the market or exchange on which they are primarily traded. For securities for which there were no sales reported that day, equity securities are generally valued at the last quoted daily bid quotation as provided by an independent pricing service on the market or exchange on which such securities are primarily traded. For securities held short for which there were no sales reported that day, the position is generally valued at the last quoted daily ask quotation as provided by an independent pricing service on the market or exchange on which such securities are primarily traded.

Debt instruments and floating rate loans (other than short-term instruments), including restricted debt instruments, are generally valued at an evaluated or composite bid as provided by an independent pricing service.

Short-term instruments with a maturity at issuance of 60 days or less may be valued at amortized cost, which approximates market value.

Exchange-traded options are generally valued at the last sale or official closing price as provided by an independent pricing service on the exchange on which such options are primarily traded. Exchange-traded options for which there were no sales reported that day are generally valued at the last daily bid quotation as provided by an independent pricing service on the exchange on which such options are primarily traded. Options not traded on an exchange are generally valued at a broker/dealer bid quotation. Foreign currency options are generally valued using an external pricing model that uses market data from an independent source.

Futures contracts are generally valued at last posted settlement price as provided by an independent pricing service on the market on which they are primarily traded. Futures contracts for which there were no trades that day for a particular position are generally valued at the closing bid quotation as provided by an independent pricing service on the market on which such futures contracts are primarily traded.

Forward foreign currency contracts are generally valued at the mean of bid and asked prices for the time period interpolated from rates provided by an independent pricing service for proximate time periods.

Swaps are generally valued at valuations provided by an independent pricing service.

Securities and other assets generally valued on the basis of information from an independent pricing service may also be valued at a broker/dealer bid quotation.

Values obtained from pricing services can utilize both dealer-supplied valuations and electronic data processing techniques, which take into account factors such as institutional-size trading in similar groups of securities, yield, quality, coupon rate, maturity, type of issue, trading characteristics, and other market data.

The values of foreign securities and other assets and liabilities expressed in foreign currencies are converted to U.S. dollars using the mean of bid and asked prices for rates provided by an independent pricing service.

SHAREHOLDER SERVICES

Investment and Withdrawal Programs

The Fund makes available certain programs designed to enable shareholders to add to or withdraw from their investment with applicable sales charges reduced or waived. These programs are generally described in the prospectus and additional details regarding certain of these programs are set forth below. These programs or waivers may be changed or discontinued by the Fund at any time without notice. Some of these programs and waivers may not be available to you if your shares are held through certain types of accounts, such as certain retirement accounts and 529 plans, or certain accounts that you maintain with your financial intermediary. You or your financial intermediary must inform MFSC of your intention to invest in the Fund under one of the programs below upon purchasing Fund shares. You can provide this information in your account application or through a separate document provided by your financial intermediary.

Letter of Intent. Out of the shareholder’s initial purchase (or subsequent purchases if necessary), 5% of the dollar amount specified in the Letter of Intent application shall be held in escrow by MFSC in the form of shares registered in the shareholder’s name. All distributions on escrowed shares will be paid to the shareholder or to the shareholder’s order. When the minimum investment so specified is completed (either prior to or by the end of the 13-month period or 36-month period, as applicable), the shareholder will be notified, the escrowed shares will be released, and the Letter of Intent will be terminated.

If the intended minimum investment amount is not completed, MFSC will redeem an appropriate number of the escrowed shares in order to pay the higher sales charge level for the amount actually purchased. Shares remaining after any such redemption will be released by MFSC. By completing and signing the Account Application or separate Service Application, the shareholder irrevocably appoints MFSC his or her attorney to surrender for redemption any or all escrowed shares with full power of substitution in the premises.

Systematic Withdrawal Plan (“SWP”). To initiate this service, shares having an aggregate value of at least $5,000 in your account in the Fund must be held on deposit by, or certificates for such shares must be deposited with, MFSC. MFSC may charge the account for services rendered and expenses incurred beyond those normally assumed by the Fund with respect to the redemption of shares. No charge is currently assessed against the account, but one could be instituted by MFSC on 60 days’ notice in writing to the shareholder in the event that the Fund ceases to assume the cost of these services. The Fund may terminate any SWP for an account if the value of the account falls below $5,000 as a result of share redemptions (other than as a result of a SWP). Any SWP may be terminated at any time by either the shareholder or the Fund.

Group Purchases. A bona fide group and all its members may be treated at MFD’s discretion as a single purchaser and, under the Right of Accumulation (but not the Letter of Intent), obtain quantity sales charge discounts on the purchase of Class A, Class A1, or 529A shares if the group (1) gives its endorsement or authorization to the investment program so that it may be used by the financial intermediary to facilitate solicitation of the membership, thus effecting economies of sales effort; (2) has a legitimate purpose other than to purchase mutual fund shares at a discount; (3) is not a group of individuals whose sole organizational nexus is as credit cardholders of a company, policyholders of an insurance company, customers of a bank or financial intermediary, clients of an investment adviser, or other similar groups; and (4) agrees to provide certification of membership of those members investing money in the MFS Funds upon the request of MFD.

Exchange Privilege

Money Market Funds

If you exchange your shares out of MFS Cash Reserve Fund, MFS Government Money Market Fund, or MFS Money Market Fund into Class A (or Class 529A shares with respect to MFS Cash Reserve Fund) of any other MFS Fund, you will pay the initial sales charge, if applicable, if you have not already paid this charge on these shares. You will not pay the charge if:

DESCRIPTION OF SHARES, VOTING RIGHTS, AND LIABILITIES

The Trust’s Declaration of Trust, as amended or amended and restated from time to time, permits the Trust’s Board of Trustees to issue an unlimited number of full and fractional shares of beneficial interest (without par value) of each series, to divide or combine the shares of any series into a greater or lesser number of shares without thereby changing the proportionate beneficial interests in that series, and to divide such shares into classes. The Board of Trustees has reserved the right to create and issue additional series and classes of shares and to classify or reclassify outstanding shares.

Each shareholder of the Fund is entitled to one vote for each dollar of net asset value (number of shares of the Fund owned times net asset value per share) of the Fund, on each matter on which the shareholder is entitled to vote. Each fractional dollar amount is entitled to a proportionate fractional vote. Except when a larger vote is required by applicable law, a majority of the voting power of the shares voted in person or by proxy on a matter will decide that matter and a plurality of the voting power of the shares voted in person or by proxy will elect a Trustee. Shareholders of all series of the Trust generally will vote together on all matters except when a particular matter affects only shareholders of a particular class or series or when applicable law requires shareholders to vote separately by series or class.

Except in limited circumstances, the Trustees may, without any shareholder vote, amend or otherwise supplement the Trust’s Declaration of Trust. Each Trust except MFS Series Trust XII and MFS Series Trust XV, or any series or class thereof, may merge or consolidate or may sell, lease, or exchange all or substantially all of its assets if authorized (either at a meeting or by written consent) by a Majority Shareholder Vote of the class, series, or trust, as applicable. MFS Series Trust XII and MFS Series Trust XV, or any series or class of MFS Series Trust XII and MFS Series Trust XV, may merge or consolidate or may sell, lease, or exchange all or substantially all of their assets without any shareholder vote to the extent permitted by law. Each Trust, or any series or class, may reincorporate or reorganize (but not with another operating entity) without any shareholder vote. The Trust, any series of the Trust, or any class of any series, may be terminated at any time: 1) by a Majority Shareholder Vote; or 2) by the Trustees by written notice to the shareholders of that series or class.
