LETTER FROM THE CEO

[Photo of Robert J. Manning]

Dear Shareholders:

The past year has been a great example of why investors should keep their eyes
on the long term.

In 2006 the Dow Jones Industrial Average returned 19%. But the Dow's upward
rise has not been without hiccups. After hitting new records in July 2007, the
Dow lost 8% in the following weeks as a crisis swept global credit markets. As
we have said before, markets can be volatile, and investors should make sure
they have an investment plan that can carry them through the peaks and troughs.

If you are focused on a long-term investment strategy, the short-term ups and
downs of the markets should not necessarily dictate portfolio action on your
part. Both the bond and stock markets are cyclical. In our view, investors who
remain committed to a long-term plan are more likely to achieve their financial
goals. We believe you should not let the headlines guide you in your investment
decisions and should be cautious about overreacting to short-term volatility.

In any market environment, we believe individual investors are best served by
following a three-pronged investment strategy of allocating their holdings
across the major asset classes, diversifying within each class, and regularly
rebalancing their portfolios to maintain their desired allocations. Of course,
these strategies cannot guarantee a profit or protect against a loss. Investing
and planning for the long term require diligence and patience, two traits that
in our experience are essential to capitalizing on the many opportunities the
financial markets can offer -- through both up and down economic cycles.

    Respectfully,

/s/ Robert J. Manning

              Average Credit Quality of
              Rated Securities (short-term) (a)            A-1
              ------------------------------------------------

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(d) Duration is a measure of how much a bond's price is likely to fluctuate
    with general changes in interest rates, e.g., if rates rise 1.00%, a bond
    with a 5-year duration is likely to lose about 5.00% of its value.
(i) For purposes of this presentation, the bond component includes both accrued
    interest amounts and the equivalent exposure from any derivative holdings,
    if applicable.
(m) The average maturity shown is calculated using the final stated maturity on
    the portfolio's holdings without taking into account any holdings which
    have been pre-refunded or pre-paid to an earlier date or which have a
    mandatory put date prior to the stated maturity. The average life shown
    takes into account these earlier dates.
(o) Less than 0.1%.
(r) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based
    on the rating assigned by Fitch, Inc. For those portfolios that hold a
    security which is not rated by any of the three agencies, the security is
    considered Not Rated. Holdings in U.S. Treasuries and government agency
    mortgage-backed securities, if any, are included in the "AAA"-rating
    category. Percentages are based on the total market value of investments as
    of 07/31/07.

From time to time "Cash & Other Net Assets" may be negative due to timing of
cash receipts.

Percentages are based on net assets as of 07/31/07, unless otherwise noted.

The portfolio is actively managed and current holdings may be different.


EXPENSE TABLE

Fund Expenses Borne by the Shareholders During the Period,
February 1, 2007 through July 31, 2007

As a shareholder of the fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on certain purchase or redemption
payments, and (2) ongoing costs, including management fees; distribution and
service (12b-1) fees; and other fund expenses. This example is intended to help
you understand your ongoing costs (in dollars) of investing in the fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the entire period February 1, 2007 through July 31,
2007.

ACTUAL EXPENSES

The first line for each share class in the following table provides information
about actual account values and actual expenses. You may use the information in
this line, together with the amount you invested, to estimate the expenses that
you paid over the period. Simply divide your account value by $1,000 (for
example, an $8,600 account value divided by $1,000 = 8.6), then multiply the
result by the number in the first line under the heading entitled "Expenses
Paid During Period" to estimate the expenses you paid on your account during
this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line for each share class in the following table provides
information about hypothetical account values and hypothetical expenses based
on the fund's actual expense ratio and an assumed rate of return of 5% per year
before expenses, which is not the fund's actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line for each share class in the table
is useful in comparing ongoing costs only, and will not help you determine the
relative total costs of owning different funds. In addition, if these
transactional costs were included, your costs would have been higher.

(h) 5% class return per year before expenses.
(p) Expenses paid is equal to each class' annualized expense ratio, as shown
    above, multiplied by the average account value over the period, multiplied
    by the number of days in the period, divided by the number of days in the
    year. Expenses paid do not include any applicable sales charges (loads). If
    these transaction costs had been included, your costs would have been
    higher.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the fund's financial performance for the semiannual period and
the past 5 fiscal years (or life of a particular share class, if shorter). Certain information reflects financial results for a
single fund share. The total returns in the table represent the rate by which an investor would have earned (or lost) on an
investment in the fund share class (assuming reinvestment of all distributions) held for the entire period.

NOTES TO FINANCIAL STATEMENTS
(unaudited)

(1) BUSINESS AND ORGANIZATION

MFS High Income Fund (the fund) is a series of MFS Series Trust III (the
trust). The trust is organized as a Massachusetts business trust and is
registered under the Investment Company Act of 1940, as amended, as an open-
end management investment company.

(2) SIGNIFICANT ACCOUNTING POLICIES

GENERAL - The preparation of financial statements in conformity with U.S.
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The fund
can invest up to 100% of its portfolio in high-yield securities rated below
investment grade. Investments in high-yield securities involve greater degrees
of credit and market risk than investments in higher-rated securities and tend
to be more sensitive to economic conditions. The fund can invest in foreign
securities, including securities of emerging market issuers. Investments in
foreign securities are vulnerable to the effects of changes in the relative
values of the local currency and the U.S. dollar and to the effects of changes
in each country's legal, political, and economic environment. The markets of
emerging markets countries are generally more volatile than the markets of
developed countries with more mature economies. All of the risks of investing
in foreign securities previously described are heightened when investing in
emerging markets countries.

INVESTMENT VALUATIONS - Equity securities, including restricted equity
securities, are generally valued at the last sale or official closing price as
reported 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 reported by an independent pricing service on the market
or exchange on which they are primarily traded. For securities held short for
which there were no sales reported for the day, the position is generally
valued at the last quoted daily ask quotation as reported by an independent
pricing service on the market or exchange on which such securities are
primarily traded. Debt instruments (other than short-term instruments),
including restricted debt instruments, are generally valued at an evaluated or
composite bid as reported by an independent pricing service. Short-term
instruments with a maturity at issuance of 60 days or less may be valued at
amortized cost, which approximates market value. Futures contracts are
generally valued at last posted settlement price as reported by an independent
pricing service on the market on which they are primarily traded. Futures
contracts for which there were no trades that day for a particular position are
generally valued at the closing bid quotation as reported by an independent
pricing service on the market on which 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 reported by an
independent pricing service for proximate time periods. Swaps are generally
valued at an evaluated bid as reported by an independent pricing service.
Open-end investment companies are generally valued at their net asset value per
share. 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 reported by an
independent pricing service.

The Board of Trustees has delegated primary responsibility for determining or
causing to be determined the value of the fund's investments (including any
fair valuation) to the adviser pursuant to valuation policies and procedures
approved by the Board. If the adviser determines that reliable market
quotations are not readily available, investments are valued at fair value as
determined in good faith by the adviser in accordance with such procedures
under the oversight of the Board of Trustees. Under the fund's valuation
policies and procedures, market quotations are not considered to be readily
available for many types of debt instruments and certain types of derivatives.
These investments are generally valued at fair value based on information from
independent pricing services. In addition, investments may be valued at fair
value if the adviser determines that an investment's value has been materially
affected by events occurring after the close of the exchange or market on which
the investment is principally traded (such as foreign exchange or market) and
prior to the determination of the fund's net asset value, or after the halting
of trading of a specific security where trading does not resume prior to the
close of the exchange or market on which the security is principally traded.
The adviser may rely on independent pricing services or other information (such
as the correlation with price movements of similar securities in the same or
other markets; the type, cost and investment characteristics of the security;
the business and financial condition of the issuer; and trading and other
market data) to assist in determining whether to fair value and at what value
to fair value an investment. The value of an investment for purposes of
calculating the fund's net asset value can differ depending on the source and
method used to determine value. When fair valuation is used, the value of
investments used to determine the fund's net asset value may differ from quoted
or published prices for the same investments.

In September 2006, FASB Statement No. 157, Fair Value Measurements (the
"Statement") was issued, and is effective for fiscal years beginning after
November 15, 2007 and for all interim periods within those fiscal years. This
Statement provides a single definition of fair value, a hierarchy for measuring
fair value and expanded disclosures about fair value measurements. Management
is evaluating the application of the Statement to the fund, and believes the
impact will be limited to expanded disclosures resulting from the adoption of
this Statement in the fund's financial statements.

REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with
institutions that the fund's investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The fund requires
that the securities collateral in a repurchase transaction be transferred to
the custodian in a manner sufficient to enable the fund to obtain those
securities in the event of a default under the repurchase agreement. The fund
monitors, on a daily basis, the value of the collateral to ensure that its
value, including accrued interest, is greater than amounts owed to the fund
under each such repurchase agreement. The fund and other funds managed by
Massachusetts Financial Services Company (MFS), may utilize a joint trading
account for the purpose of entering into one or more repurchase agreements.

FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments,
income, and expenses are converted into U.S. dollars based upon currency
exchange rates prevailing on the respective dates of such transactions. Gains
and losses attributable to foreign currency exchange rates on sales of
securities are recorded for financial statement purposes as net realized gains
and losses on investments. Gains and losses attributable to foreign exchange
rate movements on income and expenses are recorded for financial statement
purposes as foreign currency transaction gains and losses. That portion of both
realized and unrealized gains and losses on investments that results from
fluctuations in foreign currency exchange rates is not separately disclosed.

DERIVATIVE RISK - The fund may invest in derivatives for hedging or non-
hedging purposes. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains. When the fund uses derivatives as an investment to
gain market exposure, or for hedging purposes, gains and losses from derivative
instruments may be substantially greater than the derivative's original cost.
Derivative instruments include futures contracts, forward foreign currency
exchange contracts, and swap agreements.

FUTURES CONTRACTS - The fund may enter into futures contracts for the delayed
delivery of securities or currency, or contracts based on financial indices at
a fixed price on a future date. In entering such contracts, the fund is
required to deposit with the broker either in cash or securities an amount
equal to a certain percentage of the contract amount. Subsequent payments are
made or received by the fund each day, depending on the daily fluctuations in
the value of the contract, and are recorded for financial statement purposes as
unrealized gains or losses by the fund. Upon entering into such contracts, the
fund bears the risk of interest or exchange rates or securities prices moving
unexpectedly, in which case, the fund may not achieve the anticipated benefits
of the futures contracts and may realize a loss.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS - The fund may enter into forward
foreign currency exchange contracts for the purchase or sale of a specific
foreign currency at a fixed price on a future date. Risks may arise upon
entering into these contracts from the potential inability of counterparties to
meet the terms of their contracts and from unanticipated movements in the value
of the contract. The fund may enter into forward foreign currency exchange
contracts for hedging purposes as well as for non-hedging purposes. For hedging
purposes, the fund may enter into contracts to deliver or receive foreign
currency it will receive from or require for its normal investment activities.
The fund may also use contracts in a manner intended to protect foreign
currency denominated securities from declines in value due to unfavorable
exchange rate movements. For non-hedging purposes, the fund may enter into
contracts with the intent of changing the relative exposure of the fund's
portfolio of securities to different currencies to take advantage of
anticipated changes. The forward foreign currency exchange contracts are
adjusted by the daily exchange rate of the underlying currency and any gains or
losses are recorded as unrealized until the contract settlement date. On
contract settlement date, the gains or losses are recorded as realized gains or
losses on foreign currency transactions.

SWAP AGREEMENTS - The fund may enter into swap agreements. A swap is an
exchange of cash payments between the fund and another party. Net cash payments
are exchanged at specified intervals and are recorded as a realized gain or
loss in the Statement of Operations. The value of the swap is adjusted daily
and the change in value, including accruals of periodic amounts of interest to
be paid or received, is recorded as unrealized appreciation or depreciation in
the Statement of Operations. A liquidation payment received or made upon early
termination is recorded as a realized gain or loss in the Statement of
Operations. Collateral, in the form of cash or securities, may be required to
be held in segregated accounts with the fund's custodian in connection with
these agreements. Risk of loss may exceed amounts recognized on the Statement
of Assets and Liabilities. These risks include the possible lack of a liquid
market, failure of the counterparty to perform under the terms of the
agreements, and unfavorable market movement of the underlying instrument. All
swap agreements entered into by the fund with the same counterparty are
generally governed by a single master agreement, which provides for the netting
of all amounts owed by the parties under the agreement upon the occurrence of
an event of default, thereby reducing the credit risk to which such party is
exposed.

The fund holds a credit default swap in which one party makes a stream of
payments based on a fixed percentage applied to the notional amount to another
party in exchange for the right to receive a specified return in the event of a
default by a third party, such as a corporate issuer or foreign issuer, on its
obligation. The fund may enter into credit default swaps to limit or to reduce
its risk exposure to defaults of corporate and sovereign issuers or to create
direct or synthetic short or long exposure to corporate debt securities or
certain sovereign debt securities to which it is not otherwise exposed.

LOANS AND OTHER DIRECT DEBT INSTRUMENTS - The fund may invest in loans and loan
participations or other receivables. These investments may include standby
financing commitments, including revolving credit facilities, which obligate
the fund to supply additional cash to the borrower on demand. Loan
participations involve a risk of insolvency of the lending bank or other
financial intermediary.

INDEMNIFICATIONS - Under the fund's organizational documents, its officers and
trustees may be indemnified against certain liabilities and expenses arising
out of the performance of their duties to the fund. Additionally, in the normal
course of business, the fund enters into agreements with service providers that
may contain indemnification clauses. The fund's maximum exposure under these
agreements is unknown as this would involve future claims that may be made
against the fund that have not yet occurred.

SHORT TERM FEES - The fund charged a 1% redemption fee on proceeds from Class
A, Class B, Class C, and Class I shares redeemed or exchanged within 30
calendar days following their acquisition. Effective December 1, 2006, the fund
no longer charges a redemption fee. Any redemption fees charged are accounted
for as an addition to paid-in-capital.

INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All premium
and discount is amortized or accreted for financial statement purposes in
accordance with U.S. generally accepted accounting principles. All discount is
accreted for tax reporting purposes as required by federal income tax
regulations. The fund earns certain fees in connection with its floating rate
loan purchasing activities. These fees are in addition to interest payments
earned and may include amendment fees, commitment fees, facility fees, consent
fees, and prepayment fees. These fees are recorded on an accrual basis as
income in the accompanying financial statements. Dividends received in cash are
recorded on the ex-dividend date. Certain dividends from foreign securities
will be recorded when the fund is informed of the dividend if such information
is obtained subsequent to the ex-dividend date. Dividend and interest payments
received in additional securities are recorded on the ex- dividend or
ex-interest date in an amount equal to the value of the security on such date.

The fund may receive proceeds from litigation settlements. Any proceeds
received from litigation involving portfolio holdings are reflected in the
Statement of Operations in realized gain/loss if the security has been disposed
of by the fund or in unrealized gain/loss if the security is still held by the
fund. Any other proceeds from litigation not related to portfolio holdings are
reflected as other income in the Statement of Operations.

Legal fees and other related expenses incurred to preserve and protect the
value of a security owned are added to the cost of the security; other legal
fees are expensed. Capital infusions made directly to the security issuer,
which are generally non-recurring, incurred to protect or enhance the value of
high-yield debt securities, are reported as additions to the cost basis of the
security. Costs that are incurred to negotiate the terms or conditions of
capital infusions or that are expected to result in a plan of reorganization
are reported as realized losses. Ongoing costs incurred to protect or enhance
an investment, or costs incurred to pursue other claims or legal actions, are
expensed.

FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by the
fund. This amount, for the six months ended July 31, 2007, is shown as a
reduction of total expenses on the Statement of Operations.

TAX MATTERS AND DISTRIBUTIONS - The fund intends to qualify as a regulated
investment company, as defined under Subchapter M of the Internal Revenue Code,
and to distribute all of its taxable income, including realized capital gains.
Accordingly, no provision for federal income tax is required in the financial
statements. Foreign taxes, if any, have been accrued by the fund in the
accompanying financial statements.

Distributions to shareholders are recorded on the ex-dividend date. Income and
capital gain distributions are determined in accordance with income tax
regulations, which may differ from U.S. generally accepted accounting
principles. Certain capital accounts in the financial statements are
periodically adjusted for permanent differences in order to reflect their tax
character. These adjustments have no impact on net assets or net asset value
per share. Temporary differences which arise from recognizing certain items of
income, expense, gain or loss in different periods for financial statement and
tax purposes will reverse at some time in the future. Distributions in excess
of net investment income or net realized gains are temporary overdistributions
for financial statement purposes resulting from differences in the recognition
or classification of income or distributions for financial statement and tax
purposes.

Book/tax differences primarily relate to expiration of capital loss
carryforwards, amortization and accretion of debt securities, defaulted bonds,
and foreign currency transactions.

The tax character of distributions made during the current period will be
determined at fiscal year end. The tax character of distributions declared to
shareholders is as follows:

                                                               1/31/07

          Ordinary income (including any
          short-term capital gains)                         $88,555,797

The federal tax cost and the tax basis components of distributable earnings
were as follows:

          AS OF 7/31/07

          Other temporary differences                        (6,707,798)
          Net unrealized appreciation (depreciation)         27,733,739

The aggregate cost above includes prior fiscal year end tax adjustments.

As of January 31, 2007, the fund had capital loss carryforwards available to
offset future realized gains. Such losses expire as follows:

              1/31/08                              $(10,853,391)

                                                  $(414,691,473)

MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple
classes of shares, which differ in their respective distribution and service
fees. All shareholders bear the common expenses of the fund based on the value
of settled shares outstanding of each class, without distinction between share
classes. Dividends are declared separately for each class. Differences in per
share dividend rates are generally due to differences in separate class
expenses. Class B and Class 529B shares will convert to Class A and Class 529A
shares, respectively, approximately eight years after purchase.

(3) TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISER - The fund has an investment advisory agreement with MFS to
provide overall investment management and related administrative services and
facilities to the fund.

The management fee is computed daily and paid monthly at the following annual
rates:

          First $1.4 billion of average daily net assets          0.46%
          Average daily net assets in excess of $1.4 billion      0.44%

As part of a settlement agreement with the New York Attorney General concerning
market timing and related matters, MFS has agreed to reduce the management fee
to 0.39% of the fund's average daily net assets in excess of $1.4 billion for
the period March 1, 2004 through February 28, 2009. For the six months ended
July 31, 2007, the fund's average daily net assets did not exceed $1.4 billion
and therefore, the management fee was not reduced.

The management fee incurred for the six months ended July 31, 2007 was
equivalent to an annual effective rate of 0.46% of the fund's average daily net
assets.

DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of
MFS, as distributor, received $33,029 and $485 for the six months ended July
31, 2007, as its portion of the initial sales charge on sales of Class A and
Class 529A shares of the fund, respectively.

The Board of Trustees has adopted a distribution plan for certain class shares
pursuant to Rule 12b-1 of the Investment Company Act of 1940.

The fund's distribution plan provides that the fund will pay MFD for services
provided by MFD and financial intermediaries in connection with the
distribution and servicing of certain share classes. One component of the plan
is a distribution fee paid to MFD and another component of the plan is a
service fee paid to MFD. MFD may subsequently pay all, or a portion, of the
distribution and/or service fees to financial intermediaries.

unaffiliated service providers. For the six months ended July 31, 2007, these
out-of-pocket expenses, sub-accounting and other shareholder servicing costs
amounted to $481,209. The fund may also pay shareholder servicing related costs
directly to non-related parties.

Effective May 1, 2007, under a Special Servicing Agreement among MFS, each MFS
fund which invests in other MFS funds ("MFS fund-of-funds") and each underlying
fund in which a MFS fund-of-funds invests ("underlying funds"), each underlying
fund may pay a portion of each MFS fund-of-fund's transfer agent-related
expenses, including sub-accounting fees payable to financial intermediaries, to
the extent such payments do not exceed the benefits realized or expected to be
realized by the underlying fund from the investment in the underlying fund by
the MFS fund-of-fund. For the six months ended July 31, 2007, these costs for
the fund amounted to $75,399 and are reflected in the shareholder servicing
costs on the Statement of Operations.

amount is $17,500.

The administrative services fee incurred for the six months ended July 31, 2007
was equivalent to an annual effective rate of 0.0180% of the fund average daily
net assets.

The fund is one of several mutual funds in which the MFS funds-of-funds may
invest. The MFS funds-of-funds do not invest in the underlying MFS funds for
the purpose of exercising management or control. At the end of the period, the
MFS Moderate Allocation Fund and MFS Growth Allocation Fund were the owners of
record of approximately 10% and 12%, respectively, of the value of outstanding
voting shares. In addition, the MFS Lifetime 2020 Fund and the MFS Lifetime
2030 Fund were each the owners of record of less than 1% of the value of
outstanding voting shares.

(6) LINE OF CREDIT

The fund and other funds managed by MFS participate in a $1 billion unsecured
committed line of credit provided by a syndication of banks under a credit
agreement. In addition, the fund and other funds managed by MFS have
established uncommitted borrowing arrangements with certain banks. Borrowings
may be made for temporary financing needs. Interest is charged to each fund,
based on its borrowings, generally at a rate equal to the Federal Reserve funds
rate plus 0.30%. In addition, a commitment fee, based on the average daily,
unused portion of the committed line of credit, is allocated among the
participating funds at the end of each calendar quarter. For the six months
ended July 31, 2007, the fund's commitment fee and interest expense were $3,853
and $0, respectively, and are included in miscellaneous expense on the
Statement of Operations.

(7) TRANSACTIONS IN SECURITIES OF AFFILIATED ISSUERS

Affiliated issuers, as defined under the Investment Company Act of 1940, are
those in which the fund's holdings of an issuer represent 5% or more of the
outstanding voting securities of the issuer. A summary of the fund's
transactions in the securities of these issuers during the six months ended
July 31, 2007, is set forth below:

BOARD REVIEW OF INVESTMENT

ADVISORY AGREEMENT

The Investment Company Act of 1940 requires that both the full Board of
Trustees and a majority of the non-interested ("independent") Trustees, voting
separately, annually approve the continuation of the Fund's investment advisory
agreement with MFS. The Trustees consider matters bearing on the Fund and its
advisory arrangements at their meetings throughout the year, including a review
of performance data at each regular meeting. In addition, the independent
Trustees met several times over the course of three months beginning in May and
ending in July, 2007 ("contract review meetings") for the specific purpose of
considering whether to approve the continuation of the investment advisory
agreement for the Fund and the other investment companies that the Board
oversees (the "MFS Funds"). The independent Trustees were assisted in their
evaluation of the Fund's investment advisory agreement by independent legal
counsel, from whom they received separate legal advice and with whom they met
separately from MFS during various contract review meetings. The independent
Trustees were also assisted in this process by the MFS Funds' Independent Chief
Compliance Officer, a full-time senior officer appointed by and reporting to
the independent Trustees.

In connection with their deliberations regarding the continuation of the
investment advisory agreement, the Trustees, including the independent
Trustees, considered such information and factors as they believed, in light of
the legal advice furnished to them and their own business judgment, to be
relevant. The investment advisory agreement for the Fund was considered
separately, although the Trustees also took into account the common interests
of all MFS Funds in their review. As described below, the Trustees considered
the nature, quality, and extent of the various investment advisory,
administrative, and shareholder services performed by MFS under the existing
investment advisory agreement and other arrangements with the Fund.

In connection with their contract review meetings, the Trustees received and
relied upon materials that included, among other items: (i) information
provided by Lipper Inc. on the investment performance of the Fund for various
time periods ended December 31, 2006 and the investment performance of a group
of funds with substantially similar investment classifications/objectives (the
"Lipper performance universe"), as well as the investment performance of a
group of funds identified by objective criteria suggested by MFS ("MFS peer
funds"), (ii) information provided by Lipper Inc. on the Fund's advisory fees
and other expenses and the advisory fees and other expenses of comparable funds
identified by Lipper (the "Lipper expense group"), as well as the advisory fees
and other expenses of MFS peer funds, (iii) information provided by MFS on the
advisory fees of comparable portfolios of other clients of MFS, including
institutional separate accounts and other clients, (iv) information as to
whether and to what extent applicable expense waivers, reimbursements or fee
"breakpoints" are observed for the Fund, (v) information regarding MFS'
financial results and financial condition, including MFS' and certain of its
affiliates' estimated profitability from services performed for the Fund and
the MFS Funds as a whole, (vi) MFS' views regarding the outlook for the mutual
fund industry and the strategic business plans of MFS, (vii) descriptions of
various functions performed by MFS for the Funds, such as compliance monitoring
and portfolio trading practices, and (viii) information regarding the overall
organization of MFS, including information about MFS' senior management and
other personnel providing investment advisory, administrative and other
services to the Fund and the other MFS Funds. The comparative performance, fee
and expense information prepared and provided by Lipper Inc. was not
independently verified and the independent Trustees did not independently
verify any information provided to them by MFS.

The Trustees' conclusion as to the continuation of the investment advisory
agreement was based on a comprehensive consideration of all information
provided to the Trustees and not the result of any single factor. Some of the
factors that figured particularly in the Trustees' deliberations are described
below, although individual Trustees may have evaluated the information
presented differently from one another, giving different weights to various
factors. It is also important to recognize that the fee arrangements for the
Fund and other MFS Funds are the result of years of review and discussion
between the independent Trustees and MFS, that certain aspects of such
arrangements may receive greater scrutiny in some years than in others, and
that the Trustees' conclusions may be based, in part, on their consideration of
these same arrangements during the course of the year and in prior years.

Based on information provided by Lipper Inc. and MFS, the Trustees reviewed the
Fund's total return investment performance as well as the performance of peer
groups of funds over various time periods. The Trustees placed particular
emphasis on the total return performance of the Fund's Class A shares in
comparison to the performance of funds in its Lipper performance universe over
the three-year period ended December 31, 2006, which the Trustees believed was
a long enough period to reflect differing market conditions. The total return
performance of the Fund's Class A shares was in the 3rd quintile relative to
the other funds in the universe for this three-year period (the 1st quintile
being the best performers and the 5th quintile being the worst performers). The
total return performance of the Fund's Class A shares was in the 2nd quintile
for the one-year period and the 3rd quintile for the five-year period ended
December 31, 2006 relative to the Lipper performance universe. Because of the
passage of time, these performance results may differ from the performance
results for more recent periods, including those shown elsewhere in this
report.

In addition to considering the performance information provided in connection
with the contract review meetings, the independent Trustees noted that, in
light of the Fund's substandard relative performance at the time of their
contract review meetings in 2006, they had met at each of their regular
meetings since then with MFS' senior investment management personnel to discuss
the Fund's performance and MFS' efforts to improve the Fund's performance. The
independent Trustees further noted that the Fund's relative performance for the
three-year period ended December 31, 2006 had improved in comparison to the
prior year. Taking this information into account, the Trustees concluded,
within the context of their overall conclusions regarding the investment
advisory agreement, that they were satisfied with MFS' responses and efforts
relating to investment performance.

In assessing the reasonableness of the Fund's advisory fee, the Trustees
considered, among other information, the Fund's advisory fee and the total
expense ratio of the Fund's Class A shares as a percentage of average daily net
assets and the advisory fee and total expense ratios of peer groups of funds
based on information provided by Lipper Inc. and MFS. The Trustees considered
that there is an advisory fee reduction on average daily net assets over $1.4
billion, which is in effect for the Fund through February 28, 2009 as part of
MFS' settlement with the New York Attorney General concerning market timing and
related matters. The Trustees also considered that, according to the Lipper
data, the Fund's effective advisory fee rate and total expense ratio were each
lower than the Lipper expense group median.

The Trustees also considered the advisory fees charged by MFS to institutional
accounts. In comparing these fees, the Trustees considered information provided
by MFS as to the generally broader scope of services provided by MFS to the
Fund in comparison to institutional accounts, the higher demands placed on MFS'
investment personnel and trading infrastructure as a result of the daily cash
in-flows and out-flows of the Fund, and the impact on MFS and expenses
associated with the more extensive regulatory regime to which the Fund is
subject in comparison to institutional accounts.

The Trustees also considered whether the Fund is likely to benefit from any
economies of scale in the management of the Fund in the event of growth in
assets of the Fund. They noted that the Fund's advisory fee rate schedule is
subject to a contractual breakpoint that reduces the Fund's advisory fee rate
on average daily net assets over $1.4 billion and that the advisory fee rate
associated with such breakpoint is reduced during the period in which the
advisory fee reduction described above is in effect. The Trustees concluded
that the existing breakpoint was sufficient to allow the Fund to benefit from
economies of scale as its assets grow.

The Trustees also considered information prepared by MFS relating to MFS' costs
and profits with respect to the Fund, the MFS Funds considered as a group, and
other investment companies and accounts advised by MFS, as well as MFS'
methodologies used to determine and allocate its costs to the MFS Funds, the
Fund and other accounts and products for purposes of estimating profitability.

After reviewing these and other factors described herein, the Trustees
concluded, within the context of their overall conclusions regarding the
investment advisory agreement, that the advisory fees charged to the Fund
represent reasonable compensation in light of the services being provided by
MFS to the Fund.

In addition, the Trustees considered MFS' resources and related efforts to
continue to retain, attract and motivate capable personnel to serve the Fund.
The Trustees also considered current and developing conditions in the financial
services industry, including the entry into the industry of large and
well-capitalized companies which are spending, and appear to be prepared to
continue to spend, substantial sums to engage personnel and to provide services
to competing investment companies. In this regard, the Trustees also considered
the financial resources of MFS and its ultimate parent, Sun Life Financial Inc.
The Trustees also considered the advantages and possible disadvantages to the
Fund of having an adviser that also serves other investment companies as well
as other accounts.

The Trustees also considered the nature, quality, cost, and extent of
administrative, transfer agency, and distribution services provided to the Fund
by MFS and its affiliates under agreements and plans other than the investment
advisory agreement, including any 12b-1 fees the Fund pays to MFS Fund
Distributors, Inc., an affiliate of MFS. The Trustees also considered the
nature, extent and quality of certain other services MFS performs or arranges
for on the Fund's behalf, which may include securities lending programs,
directed expense payment programs, class action recovery programs, and MFS'
interaction with third-party service providers, principally custodians and
sub-custodians. The Trustees concluded that the various non-advisory services
provided by MFS and its affiliates on behalf of the Funds were satisfactory.

The Trustees also considered benefits to MFS from the use of the Fund's
portfolio brokerage commissions, if applicable, to pay for investment research
(excluding third-party research, for which MFS pays directly) and various other
factors. Additionally, the Trustees considered so-called "fall-out benefits" to
MFS such as reputational value derived from serving as investment manager to
the Fund.

Based on their evaluation of factors that they deemed to be material, including
those factors described above, the Board of Trustees, including a majority of
the independent Trustees, concluded that the Fund's investment advisory
agreement with MFS should be continued for an additional one-year period,
commencing August 1, 2007.

A discussion regarding the Board's most recent review and renewal of the Fund's
investment advisory agreement will be available on or before November 1, 2007
by clicking on the fund's name under "Select a fund" on the MFS Web site

LETTER FROM THE CEO

[Photo of Robert J. Manning]

Dear Shareholders:

The past year has been a great example of why investors should keep their eyes
on the long term.

In 2006 the Dow Jones Industrial Average returned 19%. But the Dow's upward
rise has not been without hiccups. After hitting new records in July 2007, the
Dow lost 8% in the following weeks as a crisis swept global credit markets. As
we have said before, markets can be volatile, and investors should make sure
they have an investment plan that can carry them through the peaks and troughs.

If you are focused on a long-term investment strategy, the short-term ups and
downs of the markets should not necessarily dictate portfolio action on your
part. Both the bond and stock markets are cyclical. In our view, investors who
remain committed to a long-term plan are more likely to achieve their financial
goals. We believe you should not let the headlines guide you in your investment
decisions and should be cautious about overreacting to short-term volatility.

In any market environment, we believe individual investors are best served by
following a three-pronged investment strategy of allocating their holdings
across the major asset classes, diversifying within each class, and regularly
rebalancing their portfolios to maintain their desired allocations. Of course,
these strategies cannot guarantee a profit or protect against a loss. Investing
and planning for the long term require diligence and patience, two traits that
in our experience are essential to capitalizing on the many opportunities the
financial markets can offer -- through both up and down economic cycles.

    Respectfully,

/s/ Robert J. Manning

    Robert J. Manning
    Chief Executive Officer and Chief Investment Officer
    MFS Investment Management(R)

    September 14, 2007

              Average Credit Quality of
              Rated Securities (short-term) (a)            A-1
              ------------------------------------------------

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(d) Duration is a measure of how much a bond's price is likely to fluctuate with
    general changes in interest rates, e.g., if rates rise 1.00%, a bond with a
    5-year duration is likely to lose about 5.00% of its value.
(i) For purposes of this presentation, the bond component includes both accrued
    interest amounts and the equivalent exposure from any derivative holdings,
    if applicable.
(m) The average maturity shown is calculated using the final stated maturity on
    the portfolio's holdings without taking into account any holdings which have
    been pre- refunded or pre-paid to an earlier date or which have a mandatory
    put date prior to the stated maturity. The average life shown takes into
    account these earlier dates.
(o) Less than 0.1%.
(r) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based on
    the rating assigned by Fitch, Inc. For those portfolios that hold a security
    which is not rated by any of the three agencies, the security is considered
    Not Rated. Holdings in U.S. Treasuries and government agency mortgage-backed
    securities, if any, are included in the "AAA"-rating category. Percentages
    are based on the total market value of investments as of 07/31/07.

From time to time "Cash & Other Net Assets" may be negative due to the timing
of cash receipts and/or equivalent exposure from derivative holdings.

Percentages are based on net assets as of 07/31/07, unless otherwise noted.

The portfolio is actively managed and current holdings may be different.


EXPENSE TABLE

Fund Expenses Borne by the Shareholders During the Period,
February 1, 2007 through July 31, 2007

As a shareholder of the fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on certain purchase or redemption
payments and (2) ongoing costs, including management fees; distribution and
service (12b-1) fees; and other fund expenses. This example is intended to help
you understand your ongoing costs (in dollars) of investing in the fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the entire period February 1, 2007 through July 31,
2007.

ACTUAL EXPENSES

The first line for each share class in the following table provides information
about actual account values and actual expenses. You may use the information in
this line, together with the amount you invested, to estimate the expenses that
you paid over the period. Simply divide your account value by $1,000 (for
example, an $8,600 account value divided by $1,000 = 8.6), then multiply the
result by the number in the first line under the heading entitled "Expenses
Paid During Period" to estimate the expenses you paid on your account during
this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line for each share class in the following table provides
information about hypothetical account values and hypothetical expenses based
on the fund's actual expense ratio and an assumed rate of return of 5% per year
before expenses, which is not the fund's actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line for each share class in the table
is useful in comparing ongoing costs only, and will not help you determine the
relative total costs of owning different funds. In addition, if these
transactional costs were included, your costs would have been higher.

(h) 5% class return per year before expenses.
(p) Expenses paid is equal to each class' annualized expense ratio, as shown
    above, multiplied by the average account value over the period, multiplied
    by the number of days in the period, divided by the number of days in the
    year. Expenses paid do not include any applicable sales charges (loads).
    If these transaction costs had been included, your costs would have been
    higher.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the fund's financial performance for the semiannual period and the
past 5 fiscal years. Certain information reflects financial results for a single fund share. The total returns in the table
represent the rate by which an investor would have earned (or lost) on an investment in the fund share class (assuming reinvestment
of all distributions) held for the entire period.

(a) Annualized.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(l) Interest expense and fees relate to payments made to the holder of the
    floating rate certificate from trust assets.
(n) Not annualized.
(r) Certain expenses have been reduced without which performance would have been
    lower.
(s) From time to time the fund may receive proceeds from litigation settlements,
    without which performance would be lower.
(t) Total returns do not include any applicable sales charges.
(w) Per share amount was less than $0.01.
(z) After the fund issued its January 31, 2006 financial statements, the fund
    determined that the criteria for sale accounting in FASB Statement No. 140
    had not been met for certain transfers of municipal bonds in connection with
    self-deposited inverse floaters should have been accounted for as secured
    borrowings rather than as sales. Accordingly, the expense ratio has been
    restated to reflect interest expense and fees related to payments made to
    the holder of the floating rate certificate from trust assets in connection
    with self-deposited inverse floater transactions. The impact of the
    restatement was to increase the expense ratio by 0.12%.

(1) BUSINESS AND ORGANIZATION

MFS Municipal High Income Fund (the fund) is a series of MFS Series Trust III
which is organized as a Massachusetts business trust and is registered under
the Investment Company Act of 1940, as amended, as an open-end management
investment company.

(2) SIGNIFICANT ACCOUNTING POLICIES

GENERAL - The preparation of financial statements in conformity with U.S.
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The fund
can invest up to 100% of its portfolio in high-yield securities rated below
investment grade. Investments in high-yield securities involve greater degrees
of credit and market risk than investments in higher-rated securities and tend
to be more sensitive to economic conditions. Municipal securities backed by
current or anticipated revenues from a specific project or specific assets can
be negatively affected by the discontinuance of the taxation supporting the
projects or assets or the inability to collect revenues for the project or from
the assets. If the Internal Revenue Service determines an issuer of a municipal
security has not complied with applicable tax requirements, the security could
decline in value, interest from the security could become taxable and the fund
may be required to issue Forms 1099-DIV.

INVESTMENT VALUATIONS - Debt instruments (other than short-term instruments),
including restricted debt instruments, are generally valued at an evaluated or
composite bid as reported by an independent pricing service. Short-term
instruments with a maturity at issuance of 60 days or less may be valued at
amortized cost, which approximates market value. Swaps are generally valued at
an evaluated bid as reported 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 Board of Trustees has delegated primary responsibility for determining or
causing to be determined the value of the fund's investments (including any
fair valuation) to the adviser pursuant to valuation policies and procedures
approved by the Board. If the adviser determines that reliable market
quotations are not readily available, investments are valued at fair value as
determined in good faith by the adviser in accordance with such procedures
under the oversight of the Board of Trustees. Under the fund's valuation
policies and procedures, market quotations are not considered to be readily
available for many types of debt instruments and certain types of derivatives.
These investments are generally valued at fair value based on information from
independent pricing services. In addition, investments may be valued at fair
value if the adviser determines that an investment's value has been materially
affected by events occurring after the close of the exchange or market on which
the investment is principally traded (such as foreign exchange or market) and
prior to the determination of the fund's net asset value, or after the halting
of trading of a specific security where trading does not resume prior to the
close of the exchange or market on which the security is principally traded.
The adviser may rely on independent pricing services or other information (such
as the correlation with price movements of similar securities in the same or
other markets; the type, cost and investment characteristics of the security;
the business and financial condition of the issuer; and trading and other
market data) to assist in determining whether to fair value and at what value
to fair value an investment. The value of an investment for purposes of
calculating the fund's net asset value can differ depending on the source and
method used to determine value. When fair valuation is used, the value of
investments used to determine the fund's net asset value may differ from quoted
or published prices for the same investments.

In September 2006, FASB Statement No. 157, Fair Value Measurements (the
"Statement") was issued, and is effective for fiscal years beginning after
November 15, 2007 and for all interim periods within those fiscal years. This
Statement provides a single definition of fair value, a hierarchy for measuring
fair value and expanded disclosures about fair value measurements. Management
is evaluating the application of the Statement to the fund, and believes the
impact will be limited to expanded disclosures resulting from the adoption of
this Statement in the fund's financial statements.

DERIVATIVE RISK - The fund may invest in derivatives for hedging or non-
hedging purposes. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains. When the fund uses derivatives as an investment to
gain market exposure, or for hedging purposes, gains and losses from derivative
instruments may be substantially greater than the derivative's original cost.
Derivative instruments include swap agreements.

SWAP AGREEMENTS - The fund may enter into swap agreements. A swap is an
exchange of cash payments between the fund and another party. Net cash payments
are exchanged at specified intervals and are recorded as a realized gain or
loss in the Statement of Operations. The value of the swap is adjusted daily
and the change in value, including accruals of periodic amounts of interest to
be paid or received, is recorded as unrealized appreciation or depreciation in
the Statement of Operations. A liquidation payment received or made upon early
termination is recorded as a realized gain or loss in the Statement of
Operations. Collateral, in the form of cash or securities, may be required to
be held in segregated accounts with the fund's custodian in connection with
these agreements. Risk of loss may exceed amounts recognized on the Statement
of Assets and Liabilities. These risks include the possible lack of a liquid
market, failure of the counterparty to perform under the terms of the
agreements, and unfavorable market movement of the underlying instrument. All
swap agreements entered into by the fund with the same counterparty are
generally governed by a single master agreement, which provides for the netting
of all amounts owed by the parties under the agreement upon the occurrence of
an event of default, thereby reducing the credit risk to which such party is
exposed.

The fund holds interest rate swap agreements which involve the periodic
exchange of cash flows, such as the exchange of fixed rate interest payments
for floating rate interest payments based on a notional principal amount. The
interest rates may be based on a specific financial index or the exchange of
two distinct floating rate payments. The fund may enter into an interest rate
swap in order to manage its exposure to interest rate fluctuations.

INVERSE FLOATERS - The fund invests in municipal inverse floating rate
securities which are structured by the issuer (known as primary market inverse
floating rate securities) or by an investment banker utilizing municipal bonds
which have already been issued (known as secondary market inverse floating rate
securities) to have variable rates of interest which typically move in the
opposite direction of short term interest rates. A secondary market inverse
floating rate security is created when an investment banker transfers a fixed
rate municipal bond to a special purpose trust, and causes the trust to (a)
issue floating rate certificates to third parties, in an amount equal to a
fraction of the par amount of the deposited bonds (these certificates usually
pay tax-exempt interest at short-term interest rates that typically reset
weekly; and the certificate holders typically, on seven days notice, have the
option to tender their certificates to the investment banker or another party
for redemption at par plus accrued interest), and (b) issue inverse floating
rate certificates (sometimes referred to as "inverse floaters"). If the holder
of the inverse floater transfers the municipal bonds to an investment banker
for the purpose of depositing the municipal bonds into the special purpose
trust, the inverse floating rate certificates that are issued by the trust are
referred to as "self-deposited inverse floaters." If the bonds held by the
trust are purchased by the investment banker for deposit into the trust from
someone other than the purchasers of the inverse floaters, the inverse floating
rate certificates that are issued by the trust are referred to as "externally
deposited inverse floaters." Such self-deposited inverse floaters held by the
fund are accounted for as secured borrowings, with the municipal bonds
reflected in the investments of the fund and amounts owed to the holder of the
floating rate certificate under the provisions of the trust, which amounts are
paid solely from the assets of the trust, reflected as liabilities of the fund
in the Statement of Assets and Liabilities under the caption, "Payable to the
holder of the floating rate certificate from trust assets". At July 31, 2007,
the fund's payable to the holder of the floating rate certificate from trust
assets was $56,095,831. The weighted average interest rate on the floating rate
certificates issued by the trust was 4.25%. Interest expense and fees relate to
payments made to the holder of the floating rate certificate from trust assets
in connection with self-deposited inverse floater transactions. Interest
expense and fees are recorded as incurred. For the six months ended July 31,
2007, interest expense and fess in connection with self-deposited inverse
floaters was $1,132,340. Primary and externally deposited inverse floaters held
by the fund are not accounted for as secured borrowings.

INDEMNIFICATIONS - Under the fund's organizational documents, its officers and
trustees may be indemnified against certain liabilities and expenses arising
out of the performance of their duties to the fund. Additionally, in the normal
course of business, the fund enters into agreements with service providers that
may contain indemnification clauses. The fund's maximum exposure under these
agreements is unknown as this would involve future claims that may be made
against the fund that have not yet occurred.

SHORT TERM FEES - The fund charged a 1% redemption fee on proceeds from Class
A, Class B, and Class C shares redeemed or exchanged within 30 calendar days
following their acquisition. Effective December 1, 2006, the fund no longer
charges a redemption fee. Any redemption fees charged are accounted for as an
addition to paid-in-capital.

INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All premium
and discount is amortized or accreted for financial statement purposes in
accordance with U.S. generally accepted accounting principles. All premium and
original issue discount is amortized or accreted for tax reporting purposes as
required by federal income tax regulations.

The fund may receive proceeds from litigation settlements. Any proceeds
received from litigation involving portfolio holdings are reflected in the
Statement of Operations in realized gain/loss if the security has been disposed
of by the fund or in unrealized gain/loss if the security is still held by the
fund. Any other proceeds from litigation not related to portfolio holdings are
reflected as other income in the Statement of Operations.

Legal fees and other related expenses incurred to preserve and protect the
value of a security owned are added to the cost of the security; other legal
fees are expensed. Capital infusions made directly to the security issuer,
which are generally non-recurring, incurred to protect or enhance the value of
high-yield debt securities, are reported as additions to the cost basis of the
security. Costs that are incurred to negotiate the terms or conditions of
capital infusions or that are expected to result in a plan of reorganization
are reported as realized losses. Ongoing costs incurred to protect or enhance
an investment, or costs incurred to pursue other claims or legal actions, are
expensed.

FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by the
fund. This amount, for the six months ended July 31, 2007, is shown as a
reduction of total expenses on the Statement of Operations.

TAX MATTERS AND DISTRIBUTIONS - The fund intends to qualify as a regulated
investment company, as defined under Subchapter M of the Internal Revenue Code,
and to distribute all of its taxable and tax-exempt income, including realized
capital gains. Accordingly, no provision for federal income tax is required in
the financial statements.

Distributions to shareholders are recorded on the ex-dividend date. Income and
capital gain distributions are determined in accordance with income tax
regulations, which may differ from U.S. generally accepted accounting
principles. Certain capital accounts in the financial statements are
periodically adjusted for permanent differences in order to reflect their tax
character. These adjustments have no impact on net assets or net asset value
per share. Temporary differences which arise from recognizing certain items of
income, expense, gain or loss in different periods for financial statement and
tax purposes will reverse at some time in the future. Distributions in excess
of net investment income or net realized gains are temporary overdistributions
for financial statement purposes resulting from differences in the recognition
or classification of income or distributions for financial statement and tax
purposes.

Book/tax differences primarily relate to expiration of capital loss
carryforwards, amortization and accretion of debt securities, defaulted bonds,
and secured borrowings.

The tax character of distributions made during the current period will be
determined at fiscal year end. The tax character of distributions declared to
shareholders is as follows:

                                                                1/31/07

          Ordinary income (including any
          short-term capital gains)                            $301,170
          Tax-exempt income                                  75,822,754
          -------------------------------------------------------------

          Net unrealized appreciation (depreciation)         71,034,441

The aggregate cost above includes prior fiscal year end tax adjustments.

As of January 31, 2007, the fund had capital loss carryforwards available to
offset future realized gains. Such losses expire as follows:

MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple
classes of shares, which differ in their respective distribution and service
fees. All shareholders bear the common expenses of the fund based on the value
of settled shares outstanding of each class, without distinction between share
classes. Dividends are declared separately for each class. Differences in per
share dividend rates are generally due to differences in separate class
expenses. Class B shares will convert to Class A shares approximately eight
years after purchase.

(3) TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISER - The fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
management and related administrative services and facilities to the fund.

The management fee is computed daily and paid monthly at the following annual
rates:

    First $1.4 billion of average daily net assets            0.60%
    Average daily net assets in excess of $1.4 billion        0.57%

As part of a settlement agreement with the New York Attorney General concerning
market timing and related matters, MFS has agreed to reduce the management fee
to 0.50% of the fund's average daily net assets for the period March 1, 2004
through February 28, 2009. For the six months ended July 31, 2007, this waiver
amounted to $803,786 and is reflected as a reduction of total expenses in the
Statement of Operations.

The management fee incurred for the six months ended July 31, 2007 was
equivalent to an annual effective rate of 0.50% of the fund's average daily net
assets.

DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of
MFS, as distributor, received $247,660 for the six months ended July 31, 2007,
as its portion of the initial sales charge on sales of Class A shares of the
fund.

The Board of Trustees has adopted a distribution plan for certain class shares
pursuant to Rule 12b-1 of the Investment Company Act of 1940.

The fund's distribution plan provides that the fund will pay MFD for services
provided by MFD and financial intermediaries in connection with the
distribution and servicing of certain share classes. One component of the plan
is a distribution fee paid to MFD and another component of the plan is a
service fee paid to MFD. MFD may subsequently pay all, or a portion, of the
distribution and/or service fees to financial intermediaries.


Distribution Fee Plan Table:

Total Distribution and Service Fees                                                           $1,519,874

(d) In accordance with the distribution plan for certain classes, the fund pays distribution and/or
    service fees up to these annual percentage rates of each class' average daily net assets.
(e) The annual effective rates represent actual fees incurred under the distribution plan for the six
    months ended July 31, 2007 based on each class' average daily net assets. For one year from the date
    of sale of Class B shares, assets attributable to such Class B shares are subject to the 25% annual
    Class B service fee. On assets attributable to all other Class B shares, the service fee is not
    currently in effect, but may be implemented on such date as the fund's Board of Trustees may
    determine.


Certain Class A and Class C shares are subject to a contingent deferred sales
charge in the event of a shareholder redemption within 12 months of purchase.
Class B shares are subject to a contingent deferred sales charge in the event
of a shareholder redemption within six years of purchase. All contingent
deferred sales charges are paid to MFD and during the six months ended July 31,
2007, were as follows:

                                                   AMOUNT

              Class A                             $21,538
              Class B                            $127,750
              Class C                             $23,897

SHAREHOLDER SERVICING AGENT - MFS Service Center, Inc. (MFSC), a wholly-owned
subsidiary of MFS, receives a fee from the fund for its services as shareholder
servicing agent calculated as a percentage of the average daily net assets of
the fund as determined periodically under the supervision of the fund's Board
of Trustees. For the six months ended July 31, 2007, the fee was $441,509,
which equated to 0.0519% annually of the fund's average daily net assets. MFSC
also receives payment from the fund for out-of-pocket expenses, sub-accounting
and other shareholder servicing costs which may be paid to affiliated and
unaffiliated service providers. For the six months ended July 31, 2007, these
out-of-pocket expenses, sub-accounting and other shareholder servicing costs
amounted to $267,795. The fund may also pay shareholder servicing related costs
directly to non-related parties.

ADMINISTRATOR - MFS provides certain financial, legal, shareholder
communications, compliance, and other administrative services to the fund.
Under an administrative services agreement, the fund partially reimburses MFS
the costs incurred to provide these services. The fund is charged a fixed
amount plus a fee based on average daily net assets. The fund's annual fixed
amount is $17,500.

The administrative services fee incurred for the six months ended July 31, 2007
was equivalent to an annual effective rate of 0.0177% of the fund's average
daily net assets.

TRUSTEES' AND OFFICERS' COMPENSATION - The fund pays compensation to
independent trustees in the form of a retainer, attendance fees, and additional
compensation to Board and Committee chairpersons. The fund does not pay
compensation directly to trustees or officers of the fund who are also officers
of the investment adviser, all of whom receive remuneration for their services
to the fund from MFS. Certain officers and trustees of the fund are officers or
directors of MFS, MFD, and MFSC. The fund has an unfunded, defined benefit plan
for certain retired independent trustees which resulted in a pension expense of
$2,390. This amount is included in independent trustees' compensation for the
six months ended July 31, 2007. The liability for deferred retirement benefits
payable to certain retired independent trustees amounted to $44,814 at July 31,
2007, and is included in payable for independent trustees' compensation.

OTHER - This fund and certain other MFS funds (the funds) have entered into a
services agreement (the Agreement) which provides for payment of fees by the
funds to Tarantino LLC in return for the provision of services of an
Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an
officer of the funds and the sole member of Tarantino LLC. The funds can
terminate the Agreement with Tarantino LLC at any time under the terms of the
Agreement. For the six months ended July 31, 2007, the fee paid to Tarantino
LLC was $6,285. MFS has agreed to reimburse the fund for a portion of the
payments made by the funds to Tarantino LLC in the amount of $4,211, which is
shown as a reduction of total expenses in the Statement of Operations.
Additionally, MFS has agreed to bear all expenses associated with office space,
other administrative support, and supplies provided to the ICCO.

(4) PORTFOLIO SECURITIES

Purchases and sales of investments, other than U.S. government securities,
purchased option transactions, and short-term obligations, aggregated
$306,733,522 and $263,244,874, respectively.

(5) SHARES OF BENEFICIAL INTEREST

The fund's Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest. Transactions in
fund shares were as follows:

(6) LINE OF CREDIT

The fund and other funds managed by MFS participate in a $1 billion unsecured
committed line of credit provided by a syndication of banks under a credit
agreement. In addition, the fund and other funds managed by MFS have
established uncommitted borrowing arrangements with certain banks. Borrowings
may be made for temporary financing needs. Interest is charged to each fund,
based on its borrowings, generally at a rate equal to the Federal Reserve funds
rate plus 0.30%. In addition, a commitment fee, based on the average daily,
unused portion of the committed line of credit, is allocated among the
participating funds at the end of each calendar quarter. For the six months
ended July 31, 2007, the fund's commitment fee and interest expense on the line
of credit were $4,854 and $0, respectively, and are included in miscellaneous
expense and interest expense and fees, respectively, on the Statement of
Operations.


BOARD REVIEW OF INVESTMENT

ADVISORY AGREEMENT

The Investment Company Act of 1940 requires that both the full Board of
Trustees and a majority of the non-interested ("independent") Trustees, voting
separately, annually approve the continuation of the Fund's investment advisory
agreement with MFS. The Trustees consider matters bearing on the Fund and its
advisory arrangements at their meetings throughout the year, including a review
of performance data at each regular meeting. In addition, the independent
Trustees met several times over the course of three months beginning in May and
ending in July, 2007 ("contract review meetings") for the specific purpose of
considering whether to approve the continuation of the investment advisory
agreement for the Fund and the other investment companies that the Board
oversees (the "MFS Funds"). The independent Trustees were assisted in their
evaluation of the Fund's investment advisory agreement by independent legal
counsel, from whom they received separate legal advice and with whom they met
separately from MFS during various contract review meetings. The independent
Trustees were also assisted in this process by the MFS Funds' Independent Chief
Compliance Officer, a full-time senior officer appointed by and reporting to
the independent Trustees.

In connection with their deliberations regarding the continuation of the
investment advisory agreement, the Trustees, including the independent
Trustees, considered such information and factors as they believed, in light of
the legal advice furnished to them and their own business judgment, to be
relevant. The investment advisory agreement for the Fund was considered
separately, although the Trustees also took into account the common interests
of all MFS Funds in their review. As described below, the Trustees considered
the nature, quality, and extent of the various investment advisory,
administrative, and shareholder services performed by MFS under the existing
investment advisory agreement and other arrangements with the Fund.

In connection with their contract review meetings, the Trustees received and
relied upon materials that included, among other items: (i) information
provided by Lipper Inc. on the investment performance of the Fund for various
time periods ended December 31, 2006 and the investment performance of a group
of funds with substantially similar investment classifications/objectives (the
"Lipper performance universe"), as well as the investment performance of a
group of funds identified by objective criteria suggested by MFS ("MFS peer
funds"), (ii) information provided by Lipper Inc. on the Fund's advisory fees
and other expenses and the advisory fees and other expenses of comparable funds
identified by Lipper (the "Lipper expense group"), as well as the advisory fees
and other expenses of MFS peer funds, (iii) information provided by MFS on the
advisory fees of comparable portfolios of other clients of MFS, including
institutional separate accounts and other clients, (iv) information as to
whether and to what extent applicable expense waivers, reimbursements or fee
"breakpoints" are observed for the Fund, (v) information regarding MFS'
financial results and financial condition, including MFS' and certain of its
affiliates' estimated profitability from services performed for the Fund and
the MFS Funds as a whole, (vi) MFS' views regarding the outlook for the mutual
fund industry and the strategic business plans of MFS, (vii) descriptions of
various functions performed by MFS for the Funds, such as compliance monitoring
and portfolio trading practices, and (viii) information regarding the overall
organization of MFS, including information about MFS' senior management and
other personnel providing investment advisory, administrative and other
services to the Fund and the other MFS Funds. The comparative performance, fee
and expense information prepared and provided by Lipper Inc. was not
independently verified and the independent Trustees did not independently
verify any information provided to them by MFS.

The Trustees' conclusion as to the continuation of the investment advisory
agreement was based on a comprehensive consideration of all information
provided to the Trustees and not the result of any single factor. Some of the
factors that figured particularly in the Trustees' deliberations are described
below, although individual Trustees may have evaluated the information
presented differently from one another, giving different weights to various
factors. It is also important to recognize that the fee arrangements for the
Fund and other MFS Funds are the result of years of review and discussion
between the independent Trustees and MFS, that certain aspects of such
arrangements may receive greater scrutiny in some years than in others, and
that the Trustees' conclusions may be based, in part, on their consideration of
these same arrangements during the course of the year and in prior years.

Based on information provided by Lipper Inc. and MFS, the Trustees reviewed the
Fund's total return investment performance as well as the performance of peer
groups of funds over various time periods. The Trustees placed particular
emphasis on the total return performance of the Fund's Class A shares in
comparison to the performance of funds in its Lipper performance universe over
the three-year period ended December 31, 2006, which the Trustees believed was
a long enough period to reflect differing market conditions. The total return
performance of the Fund's Class A shares was in the 2nd quintile relative to
the other funds in the universe for this three-year period (the 1st quintile
being the best performers and the 5th quintile being the worst performers). The
total return performance of the Fund's Class A shares was in the 3rd quintile
for the one-year period and the 2nd quintile for the five-year period ended
December 31, 2006 relative to the Lipper performance universe. Because of the
passage of time, these performance results may differ from the performance
results for more recent periods, including those shown elsewhere in this
report.

In the course of their deliberations, the Trustees took into account
information provided by MFS in connection with the contract review meetings, as
well as during investment review meetings conducted with portfolio management
personnel during the course of the year regarding the Fund's performance. After
reviewing these and related factors, the Trustees concluded, within the context
of their overall conclusions regarding the investment advisory agreement, that
they were satisfied with MFS' responses and efforts relating to investment
performance.

In assessing the reasonableness of the Fund's advisory fee, the Trustees
considered, among other information, the Fund's advisory fee and the total
expense ratio of the Fund's Class A shares as a percentage of average daily net
assets and the advisory fee and total expense ratios of peer groups of funds
based on information provided by Lipper Inc. and MFS. The Trustees considered
that there is an advisory fee reduction in effect for the Fund through February
28, 2009 as part of MFS' settlement with the New York Attorney General
concerning market timing and related matters. The Trustees also considered
that, according to the Lipper data, the Fund's effective advisory fee rate
(taking into account the advisory fee reduction) was approximately at the
Lipper expense group median, and the Fund's total expense ratio was lower than
the Lipper expense group median.

The Trustees also considered the advisory fees charged by MFS to institutional
accounts. In comparing these fees, the Trustees considered information provided
by MFS as to the generally broader scope of services provided by MFS to the
Fund in comparison to institutional accounts, the higher demands placed on MFS'
investment personnel and trading infrastructure as a result of the daily cash
in-flows and out-flows of the Fund, and the impact on MFS and expenses
associated with the more extensive regulatory regime to which the Fund is
subject in comparison to institutional accounts.

The Trustees also considered whether the Fund is likely to benefit from any
economies of scale in the management of the Fund in the event of growth in
assets of the Fund. They noted that the Fund's advisory fee rate schedule is
subject to a contractual breakpoint. However, such breakpoint is not applicable
because the Fund is currently subject to the advisory fee reduction described
above. Accordingly, the Trustees determined not to recommend any advisory fee
breakpoint changes at this time.

The Trustees also considered information prepared by MFS relating to MFS' costs
and profits with respect to the Fund, the MFS Funds considered as a group, and
other investment companies and accounts advised by MFS, as well as MFS'
methodologies used to determine and allocate its costs to the MFS Funds, the
Fund and other accounts and products for purposes of estimating profitability.

After reviewing these and other factors described herein, the Trustees
concluded, within the context of their overall conclusions regarding the
investment advisory agreement, that the advisory fees charged to the Fund
represent reasonable compensation in light of the services being provided by
MFS to the Fund.

In addition, the Trustees considered MFS' resources and related efforts to
continue to retain, attract and motivate capable personnel to serve the Fund.
The Trustees also considered current and developing conditions in the financial
services industry, including the entry into the industry of large and
well-capitalized companies which are spending, and appear to be prepared to
continue to spend, substantial sums to engage personnel and to provide services
to competing investment companies. In this regard, the Trustees also considered
the financial resources of MFS and its ultimate parent, Sun Life Financial Inc.
The Trustees also considered the advantages and possible disadvantages to the
Fund of having an adviser that also serves other investment companies as well
as other accounts.

The Trustees also considered the nature, quality, cost, and extent of
administrative, transfer agency, and distribution services provided to the Fund
by MFS and its affiliates under agreements and plans other than the investment
advisory agreement, including any 12b-1 fees the Fund pays to MFS Fund
Distributors, Inc., an affiliate of MFS. The Trustees also considered the
nature, extent and quality of certain other services MFS performs or arranges
for on the Fund's behalf, which may include securities lending programs,
directed expense payment programs, class action recovery programs, and MFS'
interaction with third-party service providers, principally custodians and
sub-custodians. The Trustees concluded that the various non-advisory services
provided by MFS and its affiliates on behalf of the Funds were satisfactory.

The Trustees also considered benefits to MFS from the use of the Fund's
portfolio brokerage commissions, if applicable, to pay for investment research
(excluding third-party research, for which MFS pays directly) and various other
factors. Additionally, the Trustees considered so-called "fall-out benefits" to
MFS such as reputational value derived from serving as investment manager to
the Fund.

Based on their evaluation of factors that they deemed to be material, including
those factors described above, the Board of Trustees, including a majority of
the independent Trustees, concluded that the Fund's investment advisory
agreement with MFS should be continued for an additional one-year period,
commencing August 1, 2007.

A discussion regarding the Board's most recent review and renewal of the Fund's
investment advisory agreement will be available on or before November 1, 2007
by clicking on the fund's name under "Select a fund" on the MFS Web site

LETTER FROM THE CEO

[Photo of Robert J. Manning]

Dear Shareholders:

The past year has been a great example of why investors should keep their eyes
on the long term.

In 2006 the Dow Jones Industrial Average returned 19%. But the Dow's upward
rise has not been without hiccups. After hitting new records in July 2007, the
Dow lost 8% in the following weeks as a crisis swept global credit markets. As
we have said before, markets can be volatile, and investors should make sure
they have an investment plan that can carry them through the peaks and troughs.

If you are focused on a long-term investment strategy, the short-term ups and
downs of the markets should not necessarily dictate portfolio action on your
part. Both the bond and stock markets are cyclical. In our view, investors who
remain committed to a long-term plan are more likely to achieve their financial
goals. We believe you should not let the headlines guide you in your investment
decisions and should be cautious about overreacting to short- term volatility.

In any market environment, we believe individual investors are best served by
following a three-pronged investment strategy of allocating their holdings
across the major asset classes, diversifying within each class, and regularly
rebalancing their portfolios to maintain their desired allocations. Of course,
these strategies cannot guarantee a profit or protect against a loss. Investing
and planning for the long term require diligence and patience, two traits that
in our experience are essential to capitalizing on the many opportunities the
financial markets can offer -- through both up and down economic cycles.

    Respectfully,

/s/ Robert J. Manning

              ------------------------------------------------

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(d) Duration is a measure of how much a bond's price is likely to fluctuate with
    general changes in interest rates, e.g., if rates rise 1.00%, a bond with a
    5-year duration is likely to lose about 5.00% of its value.
(i) For purposes of this presentation, the bond component includes both accrued
    interest amounts and the equivalent exposure from any derivative holdings,
    if applicable.
(m) The average maturity shown is calculated using the final stated maturity on
    the portfolio's holdings without taking into account any holdings which have
    been pre- refunded or pre-paid to an earlier date or which have a mandatory
    put date prior to the stated maturity. The average life shown takes into
    account these earlier dates.
(r) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based on
    the rating assigned by Fitch, Inc. For those portfolios that hold a security
    which is not rated by any of the three agencies, the security is considered
    Not Rated. Holdings in U.S. Treasuries and government agency mortgage-backed
    securities, if any, are included in the "AAA"-rating category. Percentages
    are based on the total market value of investments as of 07/31/07.

From time to time "Cash & Other Net Assets" may be negative due to timing of
cash receipts.

Percentages are based on net assets as of 07/31/07, unless otherwise noted.

The portfolio is actively managed and current holdings may be different.

February 1, 2007 through July 31, 2007

As a shareholder of the fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on certain purchase or redemption
payments and (2) ongoing costs, including management fees; distribution and
service (12b-1) fees; and other fund expenses. This example is intended to help
you understand your ongoing costs (in dollars) of investing in the fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the entire period February 1, 2007 through July 31,
2007.

ACTUAL EXPENSES

The first line for each share class in the following table provides information
about actual account values and actual expenses. You may use the information in
this line, together with the amount you invested, to estimate the expenses that
you paid over the period. Simply divide your account value by $1,000 (for
example, an $8,600 account value divided by $1,000 = 8.6), then multiply the
result by the number in the first line under the heading entitled "Expenses
Paid During Period" to estimate the expenses you paid on your account during
this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line for each share class in the following table provides
information about hypothetical account values and hypothetical expenses based
on the fund's actual expense ratio and an assumed rate of return of 5% per year
before expenses, which is not the fund's actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the fund and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line for each share class in the table
is useful in comparing ongoing costs only, and will not help you determine the
relative total costs of owning different funds. In addition, if these
transactional costs were included, your costs would have been higher.

(h) 5% class return per year before expenses.
(p) Expenses paid is equal to each class' annualized expense ratio, as shown
    above, multiplied by the average account value over the period, multiplied
    by the number of days in the period, divided by the number of days in the
    year. Expenses paid do not include any applicable sales charges (loads).
    If these transaction costs had been included, your costs would have been
    higher.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the fund's financial performance for the semiannual period
and the past 5 fiscal years. Certain information reflects financial results for a single fund share. The total returns in the
table represent the rate by which an investor would have earned (or lost) on an investment in the fund share class (assuming
reinvestment of all distributions) held for the entire period.

NOTES TO FINANCIAL STATEMENTS
(unaudited)

(1) BUSINESS AND ORGANIZATION

MFS High Yield Opportunities Fund (the fund) is a series of MFS Series Trust
III (the trust). The trust is organized as a Massachusetts business trust and
is registered under the Investment Company Act of 1940, as amended, as an
open-end management investment company.

(2) SIGNIFICANT ACCOUNTING POLICIES

GENERAL - The preparation of financial statements in conformity with U.S.
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The fund
can invest up to 100% of its portfolio in high-yield securities rated below
investment grade. Investments in high-yield securities involve greater degrees
of credit and market risk than investments in higher-rated securities and tend
to be more sensitive to economic conditions. The fund can invest in foreign
securities, including securities of emerging market issuers. Investments in
foreign securities are vulnerable to the effects of changes in the relative
values of the local currency and the U.S. dollar and to the effects of changes
in each country's legal, political, and economic environment. The markets of
emerging markets countries are generally more volatile than the markets of
developed countries with more mature economies. All of the risks of investing
in foreign securities previously described are heightened when investing in
emerging markets countries.

INVESTMENT VALUATIONS - Equity securities, including restricted equity
securities, are generally valued at the last sale or official closing price as
reported 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 reported by an independent pricing service on the market
or exchange on which they are primarily traded. For securities held short for
which there were no sales reported for the day, the position is generally
valued at the last quoted daily ask quotation as reported by an independent
pricing service on the market or exchange on which such securities are
primarily traded. Debt instruments (other than short-term instruments),
including restricted debt instruments, are generally valued at an evaluated or
composite bid as reported by an independent pricing service. Short-term
instruments with a maturity at issuance of 60 days or less may be valued at
amortized cost, which approximates market value. Futures contracts are
generally valued at last posted settlement price as reported by an independent
pricing service on the market on which they are primarily traded. Futures
contracts for which there were no trades that day for a particular position are
generally valued at the closing bid quotation as reported by an independent
pricing service on the market on which 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 reported by an
independent pricing service for proximate time periods. Swaps are generally
valued at an evaluated bid as reported 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 reported by an
independent pricing service.

The Board of Trustees has delegated primary responsibility for determining or
causing to be determined the value of the fund's investments (including any
fair valuation) to the adviser pursuant to valuation policies and procedures
approved by the Board. If the adviser determines that reliable market
quotations are not readily available, investments are valued at fair value as
determined in good faith by the adviser in accordance with such procedures
under the oversight of the Board of Trustees. Under the fund's valuation
policies and procedures, market quotations are not considered to be readily
available for many types of debt instruments and certain types of derivatives.
These investments are generally valued at fair value based on information from
independent pricing services. In addition, investments may be valued at fair
value if the adviser determines that an investment's value has been materially
affected by events occurring after the close of the exchange or market on
which the investment is principally traded (such as foreign exchange or
market) and prior to the determination of the fund's net asset value, or after
the halting of trading of a specific security where trading does not resume
prior to the close of the exchange or market on which the security is
principally traded. The adviser may rely on independent pricing services or
other information (such as the correlation with price movements of similar
securities in the same or other markets; the type, cost and investment
characteristics of the security; the business and financial condition of the
issuer; and trading and other market data) to assist in determining whether to
fair value and at what value to fair value an investment. The value of an
investment for purposes of calculating the fund's net asset value can differ
depending on the source and method used to determine value. When fair
valuation is used, the value of investments used to determine the fund's
net asset value may differ from quoted or published prices for the
same investments.

In September 2006, FASB Statement No. 157, Fair Value Measurements (the
"Statement") was issued, and is effective for fiscal years beginning after
November 15, 2007 and for all interim periods within those fiscal years. This
Statement provides a single definition of fair value, a hierarchy for measuring
fair value and expanded disclosures about fair value measurements. Management
is evaluating the application of the Statement to the fund, and believes the
impact will be limited to expanded disclosures resulting from the adoption of
this Statement in the fund's financial statements.

REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with
institutions that the fund's investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The fund requires
that the securities collateral in a repurchase transaction be transferred to
the custodian in a manner sufficient to enable the fund to obtain those
securities in the event of a default under the repurchase agreement. The fund
monitors, on a daily basis, the value of the collateral to ensure that its
value, including accrued interest, is greater than amounts owed to the fund
under each such repurchase agreement. The fund and other funds managed by
Massachusetts Financial Services Company (MFS), may utilize a joint trading
account for the purpose of entering into one or more repurchase agreements.

FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments,
income, and expenses are converted into U.S. dollars based upon currency
exchange rates prevailing on the respective dates of such transactions. Gains
and losses attributable to foreign currency exchange rates on sales of
securities are recorded for financial statement purposes as net realized gains
and losses on investments. Gains and losses attributable to foreign exchange
rate movements on income and expenses are recorded for financial statement
purposes as foreign currency transaction gains and losses. That portion of both
realized and unrealized gains and losses on investments that results from
fluctuations in foreign currency exchange rates is not separately disclosed.

DERIVATIVE RISK - The fund may invest in derivatives for hedging or non-
hedging purposes. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains. When the fund uses derivatives as an investment to
gain market exposure, or for hedging purposes, gains and losses from derivative
instruments may be substantially greater than the derivative's original cost.
Derivative instruments include futures contracts and swap agreements.

FUTURES CONTRACTS - The fund may enter into futures contracts for the delayed
delivery of securities or currency, or contracts based on financial indices at
a fixed price on a future date. In entering such contracts, the fund is
required to deposit with the broker either in cash or securities an amount
equal to a certain percentage of the contract amount. Subsequent payments are
made or received by the fund each day, depending on the daily fluctuations in
the value of the contract, and are recorded for financial statement purposes as
unrealized gains or losses by the fund. Upon entering into such contracts, the
fund bears the risk of interest or exchange rates or securities prices moving
unexpectedly, in which case, the fund may not achieve the anticipated benefits
of the futures contracts and may realize a loss.

SWAP AGREEMENTS - The fund may enter into swap agreements. A swap is an
exchange of cash payments between the fund and another party. Net cash payments
are exchanged at specified intervals and are recorded as a realized gain or
loss in the Statement of Operations. The value of the swap is adjusted daily
and the change in value, including accruals of periodic amounts of interest to
be paid or received, is recorded as unrealized appreciation or depreciation in
the Statement of Operations. A liquidation payment received or made upon early
termination is recorded as a realized gain or loss in the Statement of
Operations. Collateral, in the form of cash or securities, may be required to
be held in segregated accounts with the fund's custodian in connection with
these agreements. Risk of loss may exceed amounts recognized on the Statement
of Assets and Liabilities. These risks include the possible lack of a liquid
market, failure of the counterparty to perform under the terms of the
agreements, and unfavorable market movement of the underlying instrument. All
swap agreements entered into by the fund with the same counterparty are
generally governed by a single master agreement, which provides for the netting
of all amounts owed by the parties under the agreement upon the occurrence of
an event of default, thereby reducing the credit risk to which such party is
exposed. The fund holds a credit default swap in which one party makes a stream
of payments based on a fixed percentage applied to the notional amount to
another party in exchange for the right to receive a specified return in the
event of a default by a third party, such as a corporate issuer or foreign
issuer, on its obligation. The fund may enter into credit default swaps to
limit or to reduce its risk exposure to defaults of corporate and sovereign
issuers or to create direct or synthetic short or long exposure to corporate
debt securities or certain sovereign debt securities to which it is not
otherwise exposed.

HYBRID INSTRUMENTS - The fund may invest in indexed or hybrid securities on
which any combination of interest payments, the principal or stated amount
payable at maturity is determined by reference to prices of other securities,
currencies, indexes, economic factors or other measures, including interest
rates, currency exchange rates, or securities indices. The risks of investing
in hybrid instruments reflect a combination of the risks of investing in
securities, swaps, options, futures and currencies. Hybrid instruments are
potentially more volatile and carry greater market risks than traditional debt
instruments. Depending on the structure of the particular hybrid instrument,
changes in a benchmark, underlying assets or economic indicator may be
magnified by the terms of the hybrid instrument and have an even more dramatic
and substantial effect upon the value of the hybrid instrument. Also, the
prices of the hybrid instrument and the benchmark, underlying asset or economic
indicator may not move in the same direction or at the same time.

LOANS AND OTHER DIRECT DEBT INSTRUMENTS - The fund may invest in loans and loan
participations or other receivables. These investments may include standby
financing commitments, including revolving credit facilities, which obligate
the fund to supply additional cash to the borrower on demand. Loan
participations involve a risk of insolvency of the lending bank or other
financial intermediary.

INDEMNIFICATIONS - Under the fund's organizational documents, its officers and
trustees may be indemnified against certain liabilities and expenses arising
out of the performance of their duties to the fund. Additionally, in the normal
course of business, the fund enters into agreements with service providers that
may contain indemnification clauses. The fund's maximum exposure under these
agreements is unknown as this would involve future claims that may be made
against the fund that have not yet occurred.

SHORT TERM FEES - The fund charged a 1% redemption fee on proceeds from Class
A, Class B, Class C, and Class I shares redeemed or exchanged within 30
calendar days following their acquisition. Effective December 1, 2006, the fund
no longer charges a redemption fee. Any redemption fees charged are accounted
for as an addition to paid-in-capital.

INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All premium
and discount is amortized or accreted for financial statement purposes in
accordance with U.S. generally accepted accounting principles. All discount is
accreted for tax reporting purposes as required by federal income tax
regulations. The fund earns certain fees in connection with its floating rate
loan purchasing activities. These fees are in addition to interest payments
earned and may include amendment fees, commitment fees, facility fees, consent
fees, and prepayment fees. These fees are recorded on an accrual basis as
income in the accompanying financial statements. Dividends received in cash are
recorded on the ex-dividend date. Certain dividends from foreign securities
will be recorded when the fund is informed of the dividend if such information
is obtained subsequent to the ex-dividend date. Dividend and interest payments
received in additional securities are recorded on the ex- dividend or
ex-interest date in an amount equal to the value of the security on such date.

The fund may receive proceeds from litigation settlements. Any proceeds
received from litigation involving portfolio holdings are reflected in the
Statement of Operations in realized gain/loss if the security has been disposed
of by the fund or in unrealized gain/loss if the security is still held by the
fund. Any other proceeds from litigation not related to portfolio holdings are
reflected as other income in the Statement of Operations.

FEES PAID INDIRECTLY - The fund's custody fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by the
fund. This amount, for the six months ended July 31, 2007, is shown as a
reduction of total expenses on the Statement of Operations.

TAX MATTERS AND DISTRIBUTIONS - The fund intends to qualify as a regulated
investment company, as defined under Subchapter M of the Internal Revenue Code,
and to distribute all of its taxable income, including realized capital gains.
Accordingly, no provision for federal income tax is required in the financial
statements. Foreign taxes, if any, have been accrued by the fund in the
accompanying financial statements.

Distributions to shareholders are recorded on the ex-dividend date. Income and
capital gain distributions are determined in accordance with income tax
regulations, which may differ from U.S. generally accepted accounting
principles. Certain capital accounts in the financial statements are
periodically adjusted for permanent differences in order to reflect their tax
character. These adjustments have no impact on net assets or net asset value
per share. Temporary differences which arise from recognizing certain items of
income, expense, gain or loss in different periods for financial statement and
tax purposes will reverse at some time in the future. Distributions in excess
of net investment income or net realized gains are temporary overdistributions
for financial statement purposes resulting from differences in the recognition
or classification of income or distributions for financial statement and tax
purposes.

Book/tax differences primarily relate to amortization and accretion of debt
securities, defaulted bonds, derivative transactions, and treating a portion of
the proceeds from redemptions as a distribution for tax purposes.

The tax character of distributions made during the current period will be
determined at fiscal year end. The tax character of distributions declared to
shareholders is as follows:

                                                                1/31/07

MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple
classes of shares, which differ in their respective distribution and service
fees. All shareholders bear the common expenses of the fund based on the value
of settled shares outstanding of each class, without distinction between share
classes. Dividends are declared separately for each class. Differences in per
share dividend rates are generally due to differences in separate class
expenses. Class B shares will convert to Class A shares approximately eight
years after purchase.

(3) TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISER - The fund has an investment advisory agreement with MFS to
provide overall investment management and related administrative services and
facilities to the fund. The management fee is computed daily and paid monthly
at an annual rate of 0.65% of the fund's average daily net assets. As part of a
settlement agreement with the New York Attorney General concerning market
timing and related matters, MFS has agreed to reduce the management fee to
0.50% of the fund's average daily net assets for the period March 1, 2004
through February 28, 2009. For the six months ended July 31, 2007, this waiver
amounted to $598,735 and is reflected as a reduction of total expenses in the
Statement of Operations.

The investment adviser has agreed in writing to pay all of the fund's operating
expenses, exclusive of management, distribution and service, and certain other
fees and expenses, This written agreement will continue through May 31, 2008
unless changed or rescinded by the fund's Board of Trustees. For the six months
ended July 31, 2007, this reduction amounted to $721,505 and is reflected as a
reduction of total expenses in the Statement of Operations.

DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of
MFS, as distributor, received $89,820 for the six months ended July 31, 2007,
as its portion of the initial sales charge on sales of Class A shares of the
fund.

The Board of Trustees has adopted a distribution plan for certain class shares
pursuant to Rule 12b-1 of the Investment Company Act of 1940.

The fund's distribution plan provides that the fund will pay MFD for services
provided by MFD and financial intermediaries in connection with the
distribution and servicing of certain share classes. One component of the plan
is a distribution fee paid to MFD and another component of the plan is a
service fee paid to MFD. MFD may subsequently pay all, or a portion, of the
distribution and/or service fees to financial intermediaries.

(d) In accordance with the distribution plan for certain classes, the fund
    pays distribution and/or service fees up to these annual percentage rates
    of each class' average daily net assets.
(e) The annual effective rates represent actual fees incurred under the
    distribution plan for the six months ended July 31, 2007 based on each
    class' average daily net assets.

Certain Class A and Class C shares are subject to a contingent deferred sales
charge in the event of a shareholder redemption within 12 months of purchase.
Class B shares are subject to a contingent deferred sales charge in the event
of a shareholder redemption within six years of purchase. All contingent
deferred sales charges are paid to MFD and during the six months ended July 31,
2007, were as follows:

                                                          AMOUNT

              Class A                                     $2,159
              Class B                                    111,098
              Class C                                      6,867

SHAREHOLDER SERVICING AGENT - MFS Service Center, Inc. (MFSC), a wholly-owned
subsidiary of MFS, receives a fee from the fund for its services as shareholder
servicing agent calculated as a percentage of the average daily net assets of
the fund as determined periodically under the supervision of the fund's Board
of Trustees. For the six months ended July 31, 2007, the fee was $206,893,
which equated to 0.0518% annually of the fund's average daily net assets. MFSC
also receives payment from the fund for out-of-pocket expenses, sub-accounting
and other shareholder servicing costs which may be paid to affiliated and
unaffiliated service providers. For the six months ended July 31, 2007, these
out-of-pocket expenses, sub-accounting and other shareholder servicing costs
amounted to $231,359. The fund may also pay shareholder servicing related costs
directly to non-related parties.

ADMINISTRATOR - MFS provides certain financial, legal, shareholder
communications, compliance, and other administrative services to the fund.
Under an administrative services agreement, the fund partially reimburses MFS
the costs incurred to provide these services. The fund is charged a fixed
amount plus a fee based on average daily net assets. The fund's annual fixed
amount is $17,500. The administrative services fee incurred for the six months
ended July 31, 2007 was equivalent to an annual effective rate of 0.0186% of
the fund's average daily net assets.

TRUSTEES' AND OFFICERS' COMPENSATION - The fund pays compensation to
independent trustees in the form of a retainer, attendance fees, and additional
compensation to Board and Committee chairpersons. The fund does not pay
compensation directly to trustees or officers of the fund who are also officers
of the investment adviser, all of whom receive remuneration for their services
to the fund from MFS. Certain officers and trustees of the fund are officers or
directors of MFS, MFD, and MFSC. The fund has an unfunded, defined benefit plan
for certain retired independent trustees which resulted in an expense of $797.
This amount is included in independent trustees' compensation for the six
months ended July 31, 2007. The liability for deferred retirement benefits
payable to certain retired independent trustees amounted to $9,678 at July 31,
2007, and is included in payable for independent trustees' compensation.

OTHER - This fund and certain other MFS funds (the funds) have entered into a
services agreement (the Agreement) which provides for payment of fees by the
funds to Tarantino LLC in return for the provision of services of an
Independent Chief Compliance Officer (ICCO) for the funds. The ICCO is an
officer of the funds and the sole member of Tarantino LLC. The funds can
terminate the Agreement with Tarantino LLC at any time under the terms of the
Agreement. For the six months ended July 31, 2007, the fee paid to Tarantino
LLC was $2,913. MFS has agreed to reimburse the fund for a portion of the
payments made by the funds to Tarantino LLC in the amount of $1,976, which is
shown as a reduction of total expenses in the Statement of Operations.
Additionally, MFS has agreed to bear all expenses associated with office space,
other administrative support, and supplies provided to the ICCO.

The fund may invest in a money market fund managed by MFS which seeks
preservation of capital and current income. Income earned on this investment is
included in income distributions from affiliated funds on the Statement of
Operations. This money market fund does not pay a management fee to MFS.

(6) LINE OF CREDIT

The fund and other funds managed by MFS participate in a $1 billion unsecured
committed line of credit provided by a syndication of banks under a credit
agreement. In addition, the fund and other funds managed by MFS have
established uncommitted borrowing arrangements with certain banks. Borrowings
may be made for temporary financing needs. Interest is charged to each fund,
based on its borrowings, generally at a rate equal to the Federal Reserve funds
rate plus 0.30%. In addition, a commitment fee, based on the average daily,
unused portion of the committed line of credit, is allocated among the
participating funds at the end of each calendar quarter. For the six months
ended July 31, 2007, the fund's commitment fee and interest expense were $2,098
and $0, respectively, and are included in miscellaneous expense on the
Statement of Operations.


BOARD REVIEW OF INVESTMENT

ADVISORY AGREEMENT

The Investment Company Act of 1940 requires that both the full Board of
Trustees and a majority of the non-interested ("independent") Trustees, voting
separately, annually approve the continuation of the Fund's investment advisory
agreement with MFS. The Trustees consider matters bearing on the Fund and its
advisory arrangements at their meetings throughout the year, including a review
of performance data at each regular meeting. In addition, the independent
Trustees met several times over the course of three months beginning in May and
ending in July, 2007 ("contract review meetings") for the specific purpose of
considering whether to approve the continuation of the investment advisory
agreement for the Fund and the other investment companies that the Board
oversees (the "MFS Funds"). The independent Trustees were assisted in their
evaluation of the Fund's investment advisory agreement by independent legal
counsel, from whom they received separate legal advice and with whom they met
separately from MFS during various contract review meetings. The independent
Trustees were also assisted in this process by the MFS Funds' Independent Chief
Compliance Officer, a full-time senior officer appointed by and reporting to
the independent Trustees.

In connection with their deliberations regarding the continuation of the
investment advisory agreement, the Trustees, including the independent
Trustees, considered such information and factors as they believed, in light of
the legal advice furnished to them and their own business judgment, to be
relevant. The investment advisory agreement for the Fund was considered
separately, although the Trustees also took into account the common interests
of all MFS Funds in their review. As described below, the Trustees considered
the nature, quality, and extent of the various investment advisory,
administrative, and shareholder services performed by MFS under the existing
investment advisory agreement and other arrangements with the Fund.

In connection with their contract review meetings, the Trustees received and
relied upon materials that included, among other items: (i) information
provided by Lipper Inc. on the investment performance of the Fund for various
time periods ended December 31, 2006 and the investment performance of a group
of funds with substantially similar investment classifications/objectives (the
"Lipper performance universe"), as well as the investment performance of a
group of funds identified by objective criteria suggested by MFS ("MFS peer
funds"), (ii) information provided by Lipper Inc. on the Fund's advisory fees
and other expenses and the advisory fees and other expenses of comparable funds
identified by Lipper (the "Lipper expense group"), as well as the advisory fees
and other expenses of MFS peer funds, (iii) information provided by MFS on the
advisory fees of comparable portfolios of other clients of MFS, including
institutional separate accounts and other clients, (iv) information as to
whether and to what extent applicable expense waivers, reimbursements or fee
"breakpoints" are observed for the Fund, (v) information regarding MFS'
financial results and financial condition, including MFS' and certain of its
affiliates' estimated profitability from services performed for the Fund and
the MFS Funds as a whole, (vi) MFS' views regarding the outlook for the mutual
fund industry and the strategic business plans of MFS, (vii) descriptions of
various functions performed by MFS for the Funds, such as compliance monitoring
and portfolio trading practices, and (viii) information regarding the overall
organization of MFS, including information about MFS' senior management and
other personnel providing investment advisory, administrative and other
services to the Fund and the other MFS Funds. The comparative performance, fee
and expense information prepared and provided by Lipper Inc. was not
independently verified and the independent Trustees did not independently
verify any information provided to them by MFS.

The Trustees' conclusion as to the continuation of the investment advisory
agreement was based on a comprehensive consideration of all information
provided to the Trustees and not the result of any single factor. Some of the
factors that figured particularly in the Trustees' deliberations are described
below, although individual Trustees may have evaluated the information
presented differently from one another, giving different weights to various
factors. It is also important to recognize that the fee arrangements for the
Fund and other MFS Funds are the result of years of review and discussion
between the independent Trustees and MFS, that certain aspects of such
arrangements may receive greater scrutiny in some years than in others, and
that the Trustees' conclusions may be based, in part, on their consideration of
these same arrangements during the course of the year and in prior years.

Based on information provided by Lipper Inc. and MFS, the Trustees reviewed the
Fund's total return investment performance as well as the performance of peer
groups of funds over various time periods. The Trustees placed particular
emphasis on the total return performance of the Fund's Class A shares in
comparison to the performance of funds in its Lipper performance universe over
the three-year period ended December 31, 2006, which the Trustees believed was
a long enough period to reflect differing market conditions. The total return
performance of the Fund's Class A shares was in the 1st quintile relative to
the other funds in the universe for this three-year period (the 1st quintile
being the best performers and the 5th quintile being the worst performers). The
total return performance of the Fund's Class A shares was in the 1st quintile
for each of the one- and five-year periods ended December 31, 2006 relative to
the Lipper performance universe. Because of the passage of time, these
performance results may differ from the performance results for more recent
periods, including those shown elsewhere in this report.

In the course of their deliberations, the Trustees took into account
information provided by MFS in connection with the contract review meetings, as
well as during investment review meetings conducted with portfolio management
personnel during the course of the year regarding the Fund's performance. After
reviewing these and related factors, the Trustees concluded, within the context
of their overall conclusions regarding the investment advisory agreement, that
they were satisfied with MFS' responses and efforts relating to investment
performance.

In assessing the reasonableness of the Fund's advisory fee, the Trustees
considered, among other information, the Fund's advisory fee and the total
expense ratio of the Fund's Class A shares as a percentage of average daily net
assets and the advisory fee and total expense ratios of peer groups of funds
based on information provided by Lipper Inc. and MFS. The Trustees considered
that there is an advisory fee reduction in effect for the Fund through February
28, 2009 as part of MFS' settlement with the New York Attorney General
concerning market timing and related matters, and that MFS currently observes
an expense limitation for the Fund. The Trustees also considered that,
according to the Lipper data (which takes into account the advisory fee
reduction and expense limitation), the Fund's effective advisory fee rate and
total expense ratio were each lower than the Lipper expense group median.

The Trustees also considered the advisory fees charged by MFS to institutional
accounts. In comparing these fees, the Trustees considered information provided
by MFS as to the generally broader scope of services provided by MFS to the
Fund in comparison to institutional accounts, the higher demands placed on MFS'
investment personnel and trading infrastructure as a result of the daily cash
in-flows and out-flows of the Fund, and the impact on MFS and expenses
associated with the more extensive regulatory regime to which the Fund is
subject in comparison to institutional accounts.

The Trustees also considered whether the Fund is likely to benefit from any
economies of scale in the management of the Fund in the event of growth in
assets of the Fund. They noted that the Fund's advisory fee rate schedule is
not currently subject to any breakpoints. Taking into account the advisory fee
reduction and the expense limitation noted above, the Trustees determined not
to recommend any advisory fee breakpoints for the Fund at this time.

The Trustees also considered information prepared by MFS relating to MFS' costs
and profits with respect to the Fund, the MFS Funds considered as a group, and
other investment companies and accounts advised by MFS, as well as MFS'
methodologies used to determine and allocate its costs to the MFS Funds, the
Fund and other accounts and products for purposes of estimating profitability.

After reviewing these and other factors described herein, the Trustees
concluded, within the context of their overall conclusions regarding the
investment advisory agreement, that the advisory fees charged to the Fund
represent reasonable compensation in light of the services being provided by
MFS to the Fund.

In addition, the Trustees considered MFS' resources and related efforts to
continue to retain, attract and motivate capable personnel to serve the Fund.
The Trustees also considered current and developing conditions in the financial
services industry, including the entry into the industry of large and
well-capitalized companies which are spending, and appear to be prepared to
continue to spend, substantial sums to engage personnel and to provide services
to competing investment companies. In this regard, the Trustees also considered
the financial resources of MFS and its ultimate parent, Sun Life Financial Inc.
The Trustees also considered the advantages and possible disadvantages to the
Fund of having an adviser that also serves other investment companies as well
as other accounts.

The Trustees also considered the nature, quality, cost, and extent of
administrative, transfer agency, and distribution services provided to the Fund
by MFS and its affiliates under agreements and plans other than the investment
advisory agreement, including any 12b-1 fees the Fund pays to MFS Fund
Distributors, Inc., an affiliate of MFS. The Trustees also considered the
nature, extent and quality of certain other services MFS performs or arranges
for on the Fund's behalf, which may include securities lending programs,
directed expense payment programs, class action recovery programs, and MFS'
interaction with third-party service providers, principally custodians and
sub-custodians. The Trustees concluded that the various non-advisory services
provided by MFS and its affiliates on behalf of the Funds were satisfactory.

The Trustees also considered benefits to MFS from the use of the Fund's
portfolio brokerage commissions, if applicable, to pay for investment research
(excluding third-party research, for which MFS pays directly) and various other
factors. Additionally, the Trustees considered so-called "fall-out benefits" to
MFS such as reputational value derived from serving as investment manager to
the Fund.

Based on their evaluation of factors that they deemed to be material, including
those factors described above, the Board of Trustees, including a majority of
