LETTER FROM THE CHAIRMAN

[Photo of Jeffrey L. Shames]
     Jeffrey L. Shames

Dear Shareholders,
One could easily argue that the Internet represents the greatest technological
development most of us may see in our lifetimes. There is no disputing that
this new communication medium is changing forever the way we work, play, and
shop. One might also argue that investing in this new technology represents
the investment opportunity of a lifetime. The question for any investor is
whether and how to take advantage of it.

The popular press, it seems, would have us believe that by surfing the Web, we
can learn everything we need to know about investing. Indeed, there is no
doubt that Internet-delivered information and brokerage services enable
individual investors to be well informed and to trade at bargain prices. But
we believe the numbers and facts argue that, for most of us, mutual funds
purchased through an investment professional will continue to be one of the
best products for long-term investing in this new millennium.

According to a survey by the Investment Company Institute, the national
association of American investment companies, 44% of American households own
stock or bond mutual funds, while only 25.5% own individual stocks.(1) Of
course that doesn't tell us how well they did owning those funds or stocks,
but another statistic gives us a clue. In the third quarter of 1999, during a
period of volatility in the greatest bull market in history, a quarter of the
7,500 stocks tracked by Morningstar, a popular rating service, lost more than
20% of their value. But during the same period, less than 1% of the mutual
funds tracked by Morningstar -- 6 out of 10,000 funds -- were down by a
similar amount.(2) So an investor's chance of picking one of those losing
stocks was about 25 times greater than his or her chance of picking an equally
losing fund.

The numbers also show that a majority of Americans seek professional advice
when buying mutual funds. Outside of employer-sponsored retirement plans,
approximately 68% of fund shareholders state that their primary method of
purchasing shares is through an investment professional.(1)

Why do we at MFS(R) believe that mutual funds plus professional advice will
continue to define the best course of action for many investors? Let's look at
some of the characteristics of a successful long-term investment approach:

o HAVING A PLAN AND STICKING TO IT: Our experience is that successful investors
  -- those whose lives are enriched by the fruits of their investing -- share
  two characteristics. They have a plan for reaching their monetary goals, and
  they stick with that plan through up as well as down markets. And for many
  investors, working with an investment professional may be the best way to
  develop a plan. Although the Internet abounds with calculators for developing
  all sorts of investment plans, none has your investment professional's high
  level of experience and an understanding of your unique situation. And no
  calculator can counsel you during a down market, when you may be tempted to
  abandon your goals and your plan.

o DIVERSIFICATION: Few investors can afford to own a large number of holdings,
  so poor performance of one company can potentially drag down their entire
  portfolio. This is especially true when investing in volatile new areas such
  as the Internet. On the other hand, a diversified mutual fund that owns dozens
  or even hundreds of holdings is better positioned to survive a disappointment
  in one or several investments.

o GOOD IN A DOWN MARKET: As we enter the tenth year of the greatest bull market
  in history, it's easy to forget that market downturns are an almost inevitable
  part of investing. Few mutual funds, of course, are going to be up when the
  overall market is down. But as the numbers above from the third quarter of
  1999 demonstrate, mutual funds may be less likely to suffer the extreme
  downturns experienced by a large number of individual holdings when the market
  heads south.

o MFS ORIGINAL RESEARCH(R): The Internet is one of the greatest research tools
  ever invented, but it's still not the same as being eyeball to eyeball with
  the management of a company and discussing their plans for their firm's
  future.

o GOOD PERFORMANCE AT AN ACCEPTABLE LEVEL OF RISK: Investing in individual
  stocks or bonds does indeed offer the potential of exhilarating performance
  that few mutual funds even attempt. The downside is that the most exciting
  investments are also likely to be the ones that give you sleepless nights. The
  diversification and professional management of mutual funds help make them
  inherently less risky than individual stock picking, and funds are available
  in a wide range of risk profiles.

We believe that now, more than ever, mutual funds sold by an investment
professional may offer many investors the best way to participate in whatever
investment opportunities the new millennium may bring. The combination of
professional portfolio management and professional advice recognizes the key
reason that investors give us their money: because they don't want to make a
hobby or a second profession out of investing; they simply want their money to
work for them so they have a better likelihood of realizing their dreams.

As always, we appreciate your confidence in MFS and welcome any questions or
comments you may have.

    Respectfully,

/s/ Jeffrey L. Shames

    9/30/99, of the 7,500 stocks tracked by Morningstar, 1,865 lost 20% or more;
    of the 10,000 mutual funds tracked by Morningstar, six lost 20% or more.
    Mutual fund results are at net asset value; if sales charges had been
    reflected, results would have been lower.

Investments in mutual funds will fluctuate and may be worth more or less upon
redemption.

MANAGEMENT REVIEW AND OUTLOOK

[Photo of Robert J. Manning]
     Robert J. Manning

For the 12 months ended January 31, 2000, Class A shares of the Fund provided
a total return of 4.35%, Class B shares 3.63%, Class C shares 3.83%, and Class
I shares 4.68%. These returns include the reinvestment of any distributions
but exclude the effects of any sales charges and compare to a 0.53% return for
its benchmark, the Lehman Brothers High Yield Bond Index (the Lehman Index),
an unmanaged index of noninvestment-grade corporate debt. The Fund's returns
also compare to a 2.29% return for the average high current yield fund tracked
by Lipper Inc., an independent firm that reports mutual fund performance.

Q.  WHAT FACTORS CONTRIBUTED TO THE FUND'S OUTPERFORMANCE OF ITS BENCHMARK
    DURING THE PERIOD?

A.  There were two main factors that benefited the Fund's performance. First and
    foremost, we feel our bottom-up credit research led to successful avoidance
    of credit problems and bankruptcies across a variety of sectors in the
    market. Additionally, strong security selection within the
    telecommunications, media, and cable industries contributed significantly to
    total return.

Q.  CAN YOU DESCRIBE THE MARKET ENVIRONMENT FOR HIGH-YIELD SECURITIES DURING
    THE PERIOD? HOW DID THIS ENVIRONMENT AFFECT PERFORMANCE?

A.  During much of the period, the market environment for high-yield bonds was
    difficult due to the heavy supply of new bonds, which exerted downward
    pressure on the prices of existing issues. Credit problems within a variety
    of sectors, including health care and energy, caused additional weakness.
    Concerns over Medicare reforms undermined investor sentiment toward health
    care companies, and previously low oil prices resulted in earnings weakness
    at energy companies. These factors hurt bond prices in these sectors and the
    high-yield market in general. Recently, however, the market has recovered
    due to generally strong corporate earnings and attractive yields, which we
    believe will help lure investors back to the high-yield marketplace.

Q.  COULD YOU PROVIDE SOME ADDITIONAL DETAILS REGARDING THE INDUSTRIES YOU'RE
    EMPHASIZING AND WHICH HOLDINGS PRODUCED STRONG PERFORMANCE?

A.  In the telecommunications industry, widespread consolidation and
    accelerating earnings growth worldwide provided a strong boost to the Fund's
    relative performance. In the media and cable industries, robust demand for
    data transmission provided a favorable backdrop for strong anticipated
    growth. In addition, advertising spending by Internet and technology
    companies contributed solidly to earnings growth for media and cable
    companies. Given the strong demand for voice, data, and wireless
    communications, we favored the issues of telecommunications companies such
    as VoiceStream, Nextlink, Nextel Communications, and MetroNet. Our position
    in Nextel rose considerably following Microsoft's announcement that it would
    invest $600 million with the company. MetroNet, a competitive local exchange
    company (CLEC) that provides a broad range of telecommunications services,
    saw its bonds rally after it announced plans to merge with AT&T of Canada. A
    core holding in the cable and media industry was Charter Communications,
    which continued to experience rapid earnings and customer growth fueled by
    the increased usage of cable lines to access the Internet.

Q.  WHICH HOLDINGS DETRACTED FROM FUND PERFORMANCE?

A.  While the Fund's exposure to supermarket operators was relatively small,
    this highly defensive industry did not perform well during the period. Our
    holdings in companies such as Pathmark and Jitney-Jungle Stores produced
    weak results due to concerns about increasing competition from the likes of
    Wal-Mart and a generally weak pricing environment.

Q.  WHAT IS YOUR OUTLOOK FOR THE HIGH-YIELD MARKET IN THE COMING MONTHS?

A.  We expect the high-yield market to perform well in 2000. The premiums --
    that is, the yield difference that investors are being paid for owning
    high-yield bonds versus U.S. Treasury bonds -- are at historically high
    levels and, over the long term, we expect these premiums to more than
    compensate for credit risks. (Principal value and interest on Treasury
    securities are guaranteed by the U.S. government if held to maturity.) In
    addition, we think the present environment of healthy economic growth and
    low inflation is a favorable one for high-yield bonds. However, given
    interest-rate uncertainties in the world economies, careful credit selection
    will remain a primary focus for the Fund and crucial to performance.

NOTES TO PERFORMANCE SUMMARY

Class A Share Performance Including Sales Charge takes into account the
deduction of the maximum 4.75% sales charge. Class B Share Performance Including
Sales Charge takes into account the deduction of the applicable contingent
deferred sales charge (CDSC), which declines over six years from 4% to 0%. Class
C Share Performance Including Sales Charge takes into account the deduction of
the 1% CDSC applicable to Class C shares redeemed within 12 months. Class I
shares have no sales charge and are only available to certain institutional
investors.

Class B, C, and I share performance include the performance of the Fund's
Class A shares for periods prior to their inception (blended performance).
Class B and C blended performance has been adjusted to take into account the
CDSC applicable to Class B and C shares rather than the initial sales charge
(load) applicable to Class A shares. Class I share blended performance has
been adjusted to account for the fact that Class I shares have no sales
charge. These blended performance figures have not been adjusted to take into
account differences in class-specific operating expenses. Because operating
expenses of Class B and C shares are higher than those of Class A, the blended
Class B and C share performance is higher than it would have been had Class B
and C shares been offered for the entire period. Conversely, because operating
expenses of Class I shares are lower than those of Class A, the blended Class
I share peformance is lower than it would have been had Class I shares been
offered for the entire period.

All performance results reflect any applicable expense subsidies and waivers,
without which the results would have been less favorable. Subsidies and
waivers may be rescinded at any time. See the prospectus for details.
All results are historical and assume the reinvestment of capital gains.

INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE, AND SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. MORE RECENT
RETURNS MAY BE MORE OR LESS THAN THOSE SHOWN. PAST PERFORMANCE IS NO GUARANTEE
OF FUTURE RESULTS.

Lower-rated securities may provide greater returns, but they are also
associated with greater-than-average risk. These risks may increase share
price volatility. See the prospectus for details.

Investments in foreign and emerging market securities may provide superior
returns but also involve greater risk than U.S. investments. Investments in
foreign and emerging market securities may be favorably or unfavorably
affected by changes in interest rates and currency exchange rates, market

NOTES TO FINANCIAL STATEMENTS

(1) Business and Organization
MFS High Income Fund (the Fund) is a diversified 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 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. Investments in foreign securities are vulnerable to the effects of
changes in the relative values of the local currency and the U.S. dollar and to
the effects of changes in each country's legal, political, and economic
environment.

Investment Valuations - Debt securities (other than short-term obligations
which mature in 60 days or less), including listed issues, and forward
contracts are valued on the basis of valuations furnished by dealers or by a
pricing service with consideration to factors such as institutional-size
trading in similar groups of securities, yield, quality, coupon rate,
maturity, type of issue, trading characteristics, and other market data,
without exclusive reliance upon exchange or over-the-counter prices. Short-
term obligations, which mature in 60 days or less, are valued at amortized
cost, which approximates market value. Securities for which there are no such
quotations or valuations are valued in good faith, by the Trustees. Equity
securities listed on securities exchanges or reported through the NASDAQ
system are reported at market value using last sale prices. Unlisted equity
securities or listed equity securities for which last sale prices are not
available are reported at market value using last quoted bid prices.
Securities for which there are no such quotations or valuations are valued in
good faith, at fair value, by the Trustees.

Foreign Currency Translation - Investment valuations, other assets, and
liabilities initially expressed in foreign currencies are converted each
business day into U.S. dollars based upon current exchange rates. 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.

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 a foreign currency relative to the U.S. dollar. The Fund may enter
into forward 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 gains or losses are recorded as unrealized
until the contract settlement date. On contract settlement date, the gains or
losses are recorded as realized gains or losses on foreign currency
transactions.

Investment Transactions and Income - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All discount
is accreted for financial statement and tax reporting purposes as required by
federal income tax regulations. Dividends received in cash are recorded on the
ex-dividend date. Dividend and interest payments received in additional
securities are recorded on the ex-dividend or ex-interest date in an amount
equal to the value of the security on such date. The Fund uses the effective
interest method for reporting interest income on payment-in-kind (PIK) bonds.
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 calculated as a percentage of
the Fund's month end net assets. The fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by
the Fund. This amount is shown as a reduction of expenses on the Statement of
Operations.

Tax Matters and Distributions - The Fund's policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided.

Distributions to shareholders are recorded on the ex-dividend date. The Fund
distinguishes between distributions on a tax basis and a financial reporting
basis and requires that only distributions in excess of tax basis earnings and
profits be reported in the financial statements as a distribution from paid-in
capital. Differences in the recognition or classification of income between
the financial statements and tax earnings and profits, which result in
temporary over-distributions for financial statement purposes, are classified
as distributions in excess of net investment income or net realized gains.
During the year ended January 31, 2000, $63,696,263 and $409,049 were
reclassified to accumulated net realized loss on investments and foreign
currency transactions and accumulated distributions in excess of net
investment income, respectively, from paid-in capital, due to differences
between book and tax accounting for defaulted securities, currency
transactions and the expiration of capital loss carryforwards. This change had
no effect on the net assets or net asset value per share.

At January 31, 2000, the Fund, for federal income tax purposes, had a capital
loss carryforward of $111,204,470 which may be applied against any net taxable
realized gains of each succeeding year until the earlier of its utilization or
expiration on January 31, 2001, ($16,884,352), January 31, 2003, ($30,373,319),
January 31, 2004, ($35,661,057), January 31, 2007, ($17,432,351), and January
31, 2008, ($10,853,391).

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

(3) Transactions with Affiliates
Investment Adviser - The Fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services, and general office facilities. The
management fee is computed daily and paid monthly at the following annual
rates:

BASED ON AVERAGE NET ASSETS                BASED ON GROSS INCOME
- ---------------------------------------    -----------------------------------
First $200 million                0.22%    First $22 million             3.00%
In excess of $200 million        0.187%    In excess of $22 million      2.55%

The Fund pays no compensation directly to its Trustees who are officers of the
investment adviser, or to officers of the Fund, all of whom receive
remuneration for their services to the Fund from MFS. Certain officers and
Trustees of the Fund are officers or directors of MFS, MFS Fund Distributors,
Inc. (MFD), and MFS Service Center, Inc. (MFSC). The Fund has an unfunded
defined benefit plan for all of its independent Trustees and Mr. Bailey.
Included in Trustees' compensation is a net periodic pension expense of
$31,198 for the year ended January 31, 2000.

Administrator - The Fund has an administrative services agreement with MFS to
provide the Fund with certain financial, legal, shareholder servicing,
compliance, and other administrative services. As a partial reimbursement for
the cost of providing these services, the Fund pays MFS an administrative fee
at the following annual percentages of the Fund's average daily net assets:

            First $1 billion                               0.0150%
            Next $1 billion                                0.0125%
            Next $1 billion                                0.0100%
            In excess of $3 billion                        0.0000%

Distributor - MFD, a wholly owned subsidiary of MFS, as distributor, received
$449,010 for the year ended Janauary 31, 2000, as its portion of the sales
charge on sales of Class A shares of the Fund.

The Trustees have adopted a distribution plan for Class A, Class B, and Class
C shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as
follows:

The Fund's distribution plan provides that the Fund will pay MFD up to 0.35%
per annum of its average daily net assets attributable to Class A shares in
order that MFD may pay expenses on behalf of the Fund related to the
distribution and servicing of its shares. These expenses include a service fee
paid to each securities dealer that enters into a sales agreement with MFD of
up to 0.25% per annum (reduced to a maximum of 0.15% per annum for shares
purchased prior to March 1, 1991) of the Fund's average daily net assets
attributable to Class A shares and a distribution fee to MFD of up to 0.10%
per annum (reduced to a maximum of 0.05% per annum for an indefinite period)
of the Fund's average daily net assets attributable to Class A shares. MFD
retains the service fee for accounts not attributable to a securities dealer,
which amounted to $273,415 for the year ended January 31, 2000. Fees incurred
under the distribution plan during the year ended January 31, 2000, were 0.30%
of average daily net assets attributable to Class A shares on an annualized
basis.

The Fund's distribution plan provides that the Fund will pay MFD a
distribution fee of 0.75% per annum, and a service fee of up to 0.25% per
annum, of the Fund's average daily net assets attributable to Class B and
Class C shares. MFD will pay to securities dealers that enter into a sales
agreement with MFD all or a portion of the service fee attributable to Class B
and Class C shares, and will pay to such securities dealers all of the
distribution fee attributable to Class C shares. The service fee is intended
to be consideration for services rendered by the dealer with respect to Class
B and Class C shares. MFD retains the service fee for accounts not
attributable to a securities dealer, which amounted to $36,535 and $1,863 for
Class B and Class C shares, respectively, for the year ended January 31, 2000.
Fees incurred under the distribution plan during the year ended January 31,
2000, were 1.00% of average daily net assets attributable to Class B and Class
C shares, on an annualized basis.

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 following
purchase. A contingent deferred sales charge is imposed on shareholder
redemptions of Class B shares in the event of a shareholder redemption within
six years of purchase. MFD receives all contingent deferred sales charges.
Contingent deferred sales charges imposed during the year ended January 31,
2000, were $23,149, $1,382,253, and $80,596 for Class A, Class B, and Class C
shares, respectively.

Shareholder Servicing Agent - MFSC, a wholly owned subsidiary of MFS, earns a
fee for its services as shareholder servicing agent. The fee is calculated as
a percentage of the Fund's average daily net assets at an annual rate of
0.10%. Prior to April 1, 1999, the fee was calculated as a percentage of the
Fund's average daily net assets at an annual rate of 0.1125%.

(4) Portfolio Securities
Purchases and sales of investments, other than U.S. government securities,
purchased option transactions, and short-term obligations, aggregated
$1,351,706,293 and $1,224,421,533, respectively.

The cost and unrealized appreciation or depreciation in value of the
investments owned by the Fund, as computed on a federal income tax basis, are
as follows:

Aggregate cost                                                 $1,437,337,239

(6) Line of Credit
The Fund and other affiliated funds participate in an $820 million unsecured
line of credit provided by a syndication of banks under a line of credit
agreement. Borrowings may be made to temporarily finance the repurchase of Fund
shares. Interest is charged to each fund, based on its borrowings, at a rate
equal to the bank's base rate. In addition, a commitment fee, based on the
average daily unused portion of the line of credit, is allocated among the
participating funds at the end of each quarter. The commitment fee allocated to
the Fund for the year ended January 31, 2000, was $10,903. The Fund had no
borrowings during the period.

(7) Financial Instruments
The Fund trades financial instruments with off-balance-sheet risk in the
normal course of its investing activities in order to manage exposure to
market risks such as interest rates and foreign currency exchange rates. These
financial instruments include, forward foreign currency exchange contracts.
The notional or contractual amounts of these instruments represent the
investment the Fund has in particular classes of financial instruments and
does not necessarily represent the amounts potentially subject to risk. The
measurement of the risks associated with these instruments is meaningful only
when all related and offsetting transactions are considered.

At January 31, 2000, forward foreign currency sales under master netting
agreements amounted to a net receivable of $258,465 with Merrill Lynch and
$460,805 with Deutsche Bank. The Fund had sufficient cash and/or securities to
cover any commitments under these contracts.

(8) 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 year ended January
31, 2000, is set forth below:

</TABLE>

(9) Restricted Securities
The Fund may invest not more than 15% of its net assets in securities which
are subject to legal or contractual restrictions on resale. At January 31,
2000, the Fund owned the following restricted securities, excluding securities
issued under Rule 144A, constituting 1.1% of net assets which may not be
publicly sold without registration under the Securities Act of 1933. The Fund
does not have the right to demand that such securities be registered. The
value of these securities is determined by valuations furnished by dealers or
by a pricing service, or if not available, in good faith, at fair value, by
the Trustees.

INDEPENDENT AUDITORS' REPORT

To the Trustees of MFS Series Trust III and Shareholders of MFS High Income
Fund:

We have audited the accompanying statement of assets and liabilities, of MFS
High Income Fund (a series of MFS Series Trust III), including the portfolio
of investments, as of January 31, 2000, and the related statement of
operations for the year then ended, the statement of changes in net assets for
each of the two years in the period then ended, and the financial highlights
for each of the five years in the period then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of the
securities owned at January 31, 2000 by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights present
fairly, in all material respects, the financial position of MFS High Income Fund
at January 31, 2000, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then ended,
and the financial highlights for each of the five years in the period then
ended, in conformity with generally accepted accounting principles.

MFS' YEAR 2000 READINESS DISCLOSURE

MFS Investment Management(R), as an investment adviser and
on behalf of the MFS funds, is committed to the effective
use of technology in managing our portfolio investments,
delivering high-quality service to MFS fund shareholders,     [Graphic Omitted]
retirement plan participants, and MFS' institutional
clients, and supporting the financial consultants who sell
our products.

MFS can now say that it is ready for the Year 2000. Our testing has demonstrated
that MFS' computer hardware and software will recognize "00" as the Year 2000
and will not confuse those digits with 1900. All of our critical business
applications and processes have been successfully tested, and we have adopted
companywide policies that will help us maintain our readiness through the
remainder of the year. Any new technology that is brought into the company
before the end of the year will be held to the same stringent standards as our
current technology. We have also developed a vendor readiness survey, contacted
over 700 of our vendors, and established an ongoing process to review responses,
as well as to review readiness statements of new vendors and products.

MFS recognizes that fund shareholders and institutional clients also are
concerned about whether the companies whose securities are held in their
portfolios are addressing Y2K issues. As part of the MFS Original Research(R)
process of evaluating portfolio investments, one of the many relevant factors
that MFS' portfolio managers and research analysts may consider is a company's
Y2K readiness.

Y2K readiness is an enormously complex, worldwide issue. No company or
institution can guarantee that it will be unaffected by the Y2K issue. While MFS
is taking significant steps to protect the integrity of its internal systems,
there can be no assurance that these steps will be sufficient to avoid any
adverse impact on MFS fund shareholders, retirement plan participants, or
institutional clients.

If you have further questions regarding MFS' Year 2000 Readiness Program, please
