      SHARES 13.58%, AND CLASS C SHARES 13.62% FOR THE 12 MONTHS ENDED AUGUST
      31, 1996. ALL OF THESE RETURNS ARE AT NET ASSET VALUE.
 
   *  BOND AND STOCK MARKETS AROUND THE WORLD POSTED GAINS OVER THE PAST YEAR
      DESPITE VERY DISSIMILAR ECONOMIC CONDITIONS IN KEY REGIONS. JAPAN BEGAN TO

      CONDITIONS, AND THE UNITED STATES CONTINUED ON ITS PATH OF GRADUAL 
      EXPANSION.
 
   *  THE FUND HAS FOLLOWED A DISTINCT POLICY OF FAVORING MARKETS OUTSIDE THE

      OF THE STATE OF THE GLOBAL ECONOMY.
 
   *  IN CONTRAST TO THE ROBUST GROWTH AND FEARS OF INFLATION IN THE UNITED

LETTER FROM THE CHAIRMAN                   


                           Dear Shareholders: 
                           
   [Photo of A.            In an environment of ever-changing market conditions
   Keith Brokin]           and changes among relative value rankings in
                           different asset types, Class A shares of the Fund
                           provided a total return of 14.23%, Class B shares
                           13.58%, and Class C shares 13.62% for the 12 months
                           ended August 31, 1996. All of these returns assume
                           the reinvestment of distributions but exclude the
                           effects of any sales charges, and they compare to the
one-year returns for the following unmanaged indices: 18.72% for the Standard &
Poor's 500 Composite Index, a popular index of common stock performance; 8.19%
for the Morgan Stanley Capital International EAFE (Europe, Australia, Far East)
Index, an index of international stocks; 4.11% for the Lehman Brothers Aggregate
Bond Index, an index of government and corporate bonds including U.S. Treasury,
government agency, corporate bond, and mortgage-backed securities; and 8.67% for
the J.P. Morgan Non-Dollar Government Bond Index, an international bond index.
We believe the Fund's relative favorable performance has been achieved with less
risk (lower volatility) than would have been achieved by investing exclusively
in any one class and stems from the combined effect of deliberate changes in
asset mix and issue selection, as well as from a bias toward the U.S. dollar
compared to local foreign currencies.
     During the past 12 months, bond and stock markets around the world posted
gains despite very dissimilar economic conditions in key regions. Japan began to
emerge from economic recession, Europe remained mired in recession-like
conditions, and the United States continued on its path of gradual expansion.
During this period, the Fund followed a distinct policy of favoring markets
(both bond and stock) outside the United States. Within that basic stance, we
made several changes in asset mix which could be described as both tactical
(shorter term) and strategic (longer term). A key example of these changes was a
selling off of U.S. bonds which anticipated the downturn in U.S. fixed-income
markets during 1996's first quarter. In the equity markets, we likewise changed
the Fund's positions among asset classes. For example, when U.S. small-company
stocks went into a corrective phase in June and July, we were extremely
underweighted in U.S. stocks (only 15% of the portfolio). We have recently begun
to add to this position in anticipation of a price recovery. During the past 12
months, we have also held positions in high-yield corporate bonds and in
emerging market bonds


                                                                           1

LETTER FROM THE CHAIRMAN - continued
 
(mostly Brady bonds). At present, however, both the high-yield corporate and
Brady bond positions have been reduced to zero after achieving gains.
     Some of the Fund's key investments represent consistently held positions
for us and have not involved major changes. These would include stock holdings
in Asia, notably in Malaysia and Hong Kong. Other consistent areas of interest
have been the United Kingdom and Sweden, particularly in the latter's
pharmaceutical industry.
     We continue to manage this Fund not as a market-timing vehicle or a
balanced fund, but rather as the expression of the best relative value choices
available to MFS experts that can be reasonably researched and managed. The
reports of the managers of each portfolio who have helped the Fund achieve good
performance over the past year may be found on the following pages.
     We appreciate your support and welcome any questions or comments you may
have.

Respectfully,


 
/s/ A. Keith Brodkin               /s/ James T. Swanson

PORTFOLIO ALLOCATION
 
                                 [PIE CHART]
 
U.S. STOCK MARKET - 16.6%
Our holdings in U.S. equities range across a variety of industries and
incorporate both value and growth strategies. Recent additions to the portfolio
include Alco Standard (paper and office products distribution); Cabletron
Systems (telecommunications equipment); and St. Jude Medical (medical-device
technology). Currently, our top three sectors are leisure (15.1%), technology
(13.8%), and financial services (12.0%). Our current outlook remains cautious.
Corporate profits have so far exceeded our expectations; however, we believe
that the rise in long-term interest rates is likely to have a dampening effect
on stock market performance.
                                                         -- John F. Brennan, Jr.

- -------------------------------------------------------------------------------
 
INTERNATIONAL STOCK MARKETS - 43.2%
Internationally, we emphasize stock selection as opposed to country or industry
selection. Priority is placed on companies which we believe will generate
above-average earnings growth and which are trading at attractive valuations,
regardless of their home country.











 
                                                                              3
<PAGE>   6
 
INTERNATIONAL STOCK MARKETS - continued
 
As of August 31, 1996, approximately 43% of the Fund's assets were invested in
international stocks. Over the past quarter, there has been little change to the
broad regional exposures, which are 50% for Europe, 46% for Asia/Pacific, and 4%
for the Americas. The largest individual country exposures are Japan (20%), the
United Kingdom (15%), and Sweden (11%). Roughly 20% of our international
holdings are in emerging markets, 18% of which are in Southeast Asia.
 
We continue to find few opportunities in cyclical stocks due to our view on
valuations at this point in the economic cycle. As a result, most of our recent
purchases and additions have been in companies which we believe will show steady
earnings growth regardless of the state of the global economy. Examples include
Canadian National Railway, Rhone Poulenc Rorer (a French pharmaceuticals
company), Nitto Denko (a Japanese industrial materials conglomerate), and Enator
(a Swedish information technology company).

- -------------------------------------------------------------------------------
 
U.S. GOVERNMENT BOND MARKET
The U.S. government bond market retreated during the past 12 months as the U.S.
economic outlook brightened significantly. Rates on 10-year Treasury bonds
increased from 6.25% at the beginning of the year to around 7% at the end of
August. After being concerned about slow growth at the end of 1995, the market
is currently concerned that faster growth could lead the Federal Reserve Board
to raise interest rates during the next few months. U.S. payrolls continue to
grow at a brisk rate of approximately 250,000 per month and hourly earnings have
begun to increase, albeit gradually. Despite the backup in rates, new home sales
and auto sales continue to increase. Looking forward, we suspect that the brisk
pace of economic activity could lead to higher interest rates over the balance
of 1996. Given our cautious view for this sector, the Fund continues to maintain
no exposure at this time.

INTERNATIONAL BOND MARKETS - 13.9%
 
While the U.S. bond market barely kept pace with short-term money market
instruments over the past 12 months, most foreign markets generated double-digit
returns. Signs of robust growth and fears of rising inflation ended the U.S.
rally in early 1996. In contrast, the rally in the major foreign markets has
been sustained by moderate to slow growth, benign inflation, fiscal austerity
programs, and/or easing monetary policy. As we anticipated, this environment
brought about substantial tightening of yield spreads. Thus, the higher-yielding
markets, such as Italy, Spain, Sweden, and Australia, provided the best
performance. The portfolio benefited from our emphasis on these markets as well
as from our investments in some of the less-developed markets.
 
We recently adopted a more cautious stance with regard to prospects for further
spread tightening within Europe, since the markets there are once again focused
on the risk that the European Monetary Union planned for 1999 will shake itself
apart. A clearer picture should emerge this fall during the 1997 budget
negotiations and as evidence accumulates regarding convergence or divergence of
growth and inflation within Europe. Australia and Canada remain attractive based
upon what we regard as improving fundamentals. In Japan, we believe the fragile
nature of the recovery could support the bond market over the near term, but it
may also hamper plans to reduce fiscal stimulus. Over time, we expect improved
growth and/or fiscal pressure to push yields higher.

PERFORMANCE SUMMARY
 
The information on the following page illustrates the historical performance of
MFS World Asset Allocation Fund in comparison to various market indicators. In
the graph Class A share results reflect the deduction of the 4.75% maximum sales
charge on the initial investment, while Class B share results reflect the
applicable contingent deferred sales charge (CDSC) which declines over six years
as follows: 4%, 4%, 3%, 3%, 2%, 1%, 0%. Class C shares have no initial sales
charge but, along with Class B shares, have higher annual fees and expenses than
Class A shares. Class C share purchases made on or after April 1, 1996 will be
subject to a 1% CDSC if redeemed within 12 months of purchase. Benchmark
comparisons are unmanaged and do not reflect the deduction of any fees or
expenses. You cannot invest in an index. All results reflect the reinvestment of
all dividends and capital gains.

AVERAGE ANNUAL TOTAL RETURNS - continued
 
In the previous table, we have included the average annual total returns of all
global flexible portfolio funds (including the Fund) tracked by Lipper
Analytical Services, Inc. for the applicable time periods (42 and 40 funds for
the one-year period ended August 31, 1996, and for the period from August 1,
1994 through August 31, 1996, respectively). Because these returns do not
reflect any applicable sales charges, we have also included the Fund's results
at net asset value (no sales charge) for comparison.
 
All results are historical and, therefore, are not an indication of future
results. The principal value and income return of an investment in a mutual fund
will vary with changes in market conditions, and shares, when redeemed, may be
worth more or less than their original cost. Performance results reflect any
applicable expense subsidies and waivers, without which the performance results
would have been less favorable. The subsidy may be rescinded by MFS at any time.
 
- --------------------------------------------------------------------------------
TAX FORM SUMMARY
 
In January 1997, shareholders will be mailed a Tax Form Summary reporting the
federal tax status of all distributions paid during the calendar year 1996.
 
FEDERAL INCOME TAX INFORMATION ON DISTRIBUTIONS
 
MFS World Asset Allocation Fund has designated $2,458,766 as a long-term capital
gain distribution.
 
FOREIGN TAX CREDIT
 
The Fund is estimated to have derived approximately 24.82% of its ordinary
income from dividends paid by foreign companies, and to have paid foreign taxes
equivalent to approximately 3.39% of its ordinary income.
 
DIVIDENDS RECEIVED DEDUCTION
 
For the year ended August 31, 1996, the amount of distributions from ordinary
income eligible for the 70% dividends-received deduction for corporations came
to 2.21%.

NOTES TO FINANCIAL STATEMENTS
 
(1) BUSINESS AND ORGANIZATION
MFS World Asset Allocation Fund (the Fund) is a non-diversified series of MFS
Series Trust I (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. 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 effects of changes in
each country's legal, political and economic environment.
 
Investment Valuations - Equity securities listed on securities exchanges or
reported through the NASDAQ system are valued at last sale prices. Unlisted
equity securities or listed equity securities for which last sale prices are not
available are valued at last quoted bid prices. 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. Non-U.S. dollar denominated short-term
obligations are valued at amortized cost as calculated in the base currency and
translated into U.S. dollars at the closing daily exchange rate. Futures
contracts, options and options on futures contracts listed on commodities
exchanges are valued at closing settlement prices. Over-the-counter options are
valued by brokers through the use of a pricing model which takes into account
closing bond valuations, implied volatility and short-term repurchase rates.
 
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
 



                                   
                                                                              23
<PAGE>   26
 
NOTES TO FINANCIAL STATEMENTS - continued
 
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.
 
Deferred Organization Expenses - Costs incurred by the Fund in connection with
its organization have been deferred and are being amortized on a straight-line
basis over a five-year period beginning on the date of commencement of
investment operations of the Fund.
 
Written Options - The Fund may write covered call or put options for which
premiums are received and are recorded as liabilities, and are subsequently
adjusted to the current value of the options written. Premiums received from
writing options which expire are treated as realized gains. Premiums received
from writing options which are exercised or are closed are offset against the
proceeds or amount paid on the transaction to determine the realized gain or
loss. If a put option is exercised, the premium reduces the cost basis of the
securities purchased by the Fund. The Fund, as writer of an option, may have no
control over whether the underlying securities may be sold (call) or purchased
(put) and, as a result, bears the market risk of an unfavorable change in the
price of the securities underlying the written option. In general, written call
options may serve as a partial hedge against decreases in value in the
underlying securities to the extent of the premium received. Written options may
also be used as a part of an income producing strategy reflecting the view of
the Fund's management on the direction of interest rates.
 
Futures Contracts - The Fund may enter into futures contracts for the delayed
delivery of securities, currency or contracts based on financial indices at a
fixed price on a future date. The Fund is required to deposit 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 underlying security, and are recorded for
financial statement purposes as unrealized gains or losses by the Fund. The
Fund's investment in futures contracts is designed to hedge against anticipated
future changes in interest or exchange rates or securities prices. Investments
in interest rate futures for purposes other than hedging may be made to modify
the duration of the portfolio without incurring the additional transaction costs
involved in buying and selling the underlying securities. Investments in
currency futures for purposes other than hedging may be made to change the
Fund's relative position in one or more currencies without buying and selling
portfolio assets. Investments in equity-index contracts, or contracts on related
options, for purposes other than hedging may be made when the Fund has cash on
hand and wishes to participate in anticipated market appreciation while cash is
being invested. Should interest or exchange rates
 




24
<PAGE>   27
 
NOTES TO FINANCIAL STATEMENTS - continued
 
or securities prices move unexpectedly, 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 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 will 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.
It 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 for financial statement purposes as unrealized until the contract
settlement date.
 
Swap Agreements - The Fund may enter into swap agreements. A swap is an exchange
of cash payments between the Fund and another party which is based on a specific
financial index. Cash payments are exchanged at specified intervals and the
expected income or expense is recorded on the accrual basis. The value of the
swap is adjusted daily and change in value is recorded as unrealized
appreciation and depreciation. Risks may arise upon entering into these
agreements from the potential inability of counterparties to meet the terms of
their contract and from unanticipated changes in the value of the financial
index on which the swap agreement is based. The Fund uses swaps for both hedging
and non-hedging purposes. For hedging purposes, the Fund may use swaps to reduce
its exposure to interest and foreign exchange rate fluctuations. For non-hedging
purposes, the Fund may use swaps to take a position on anticipated changes in
the underlying financial index.
 
Investment Transactions and Income - Investment transactions are recorded on the
trade date. Interest income is recorded on the accrual basis. All premium and
original issue discount are amortized or accreted for both financial statement
and tax reporting purposes as required by federal income tax regulations.
Dividend income is recorded on the ex-dividend date for dividends received in
cash. 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, whereby interest income on PIK bonds is recorded
ratably by the Fund at a constant yield to maturity. Legal fees and other
related





 
                                                                              25
<PAGE>   28
 
NOTES TO FINANCIAL STATEMENTS - continued
 
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, which are generally non-recurring, incurred to protect or enhance the
value of high-yield debt securities, are reported as an addition 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 reported as operating expenses.
 
Fees Paid Indirectly - The Fund's custodian bank calculates its fee based on the
Fund's average daily net assets. This fee is reduced according to an expense
offset arrangement with Investors Bank & Trust Co., the dividend disbursing
agent, which provides for partial reimbursement of custody fees based on a
formula developed to measure the value of cash deposited by the Fund with the
custodian and with the dividend disbursing agent. 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 net taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided.
 
The Fund files a tax return annually using tax accounting methods required under
provisions of the Code which may differ from generally accepted accounting
principles, the basis on which these financial statements are prepared.
Accordingly, the amount of net investment income and net realized gain reported
on these financial statements may differ from that reported on the Fund's tax
return, and consequently, the character of distributions to shareholders
reported in the financial highlights may differ from that reported to
shareholders on Form 1099-DIV. Foreign taxes have been provided for on interest
and dividend income earned on foreign investments in accordance with the
applicable country's tax rates and to the extent unrecoverable are recorded as a
reduction of investment income. 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 are reported in the financial statements as a tax return of
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 accumulated net realized
gains. During the year ended August 31, 1996, $3,065,668 was reclassified from
accumulated net realized gain on investments to accumulated undistributed net
investment income due to differences between book

NOTES TO FINANCIAL STATEMENTS - continued
 
and tax accounting for mortgage-backed securities and currency transactions.
This change had no effect on the net assets or net asset value per share. At
August 31, 1996, accumulated undistributed net investment income under book
accounting was different from tax accounting due to temporary differences in
accounting for foreign currency transactions.
 
Multiple Classes of Shares of Beneficial Interest - The Fund offers Class A,
Class B and Class C shares. The three classes of shares differ in their
respective shareholder servicing agent, distribution and service fees. All
shareholders bear the common expenses of the Fund pro rata based on the average
daily net assets of each class, without distinction between share classes.
Dividends are declared separately for each class. No class has preferential
dividend rights; differences in per share dividend rates are generally due to
differences in separate class expenses.
 
(3) TRANSACTIONS WITH AFFILIATES
Investment Adviser - The Fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services, and general office facilities. The
management fee is computed daily and paid monthly at an effective annual rate of
0.60% of average daily net assets.
 
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 of the 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 its independent Trustees and Mr. Bailey. Included in Trustees'
compensation is a net periodic pension expense of $6,406 for the year ended
August 31, 1996.
 
Distributor - MFD, a wholly owned subsidiary of MFS, as distributor, received
$114,694 for the year ended August 31, 1996, as its portion of the sales charge
on sales of Class A shares of the Fund. The Trustees have adopted separate
distribution plans for Class A, Class B and Class C shares pursuant to Rule
12b-1 of the Investment Company Act of 1940 as follows:
 
The Class A distribution plan provides that the Fund will pay MFD up to 0.50%
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
to each securities dealer that enters into a sales agreement with MFD of up to
0.25% per annum of the Fund's average daily net assets attributable to Class A

other such distribution-related expenses that are approved by the Fund. MFD
retains the service fee for accounts not attributable to a securities dealer
which amounted to $7,610 for the year ended August 31, 1996. MFD waived a
portion of its fee, which is reflected as a reduction of expenses on the
Statement of Operations. Fees, net of waiver, incurred under the distribution
plan during the year ended August 31, 1996 were 0.45% of average daily net
assets attributable to Class A shares on an annualized basis.

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 additional
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 $5,617 and $2,269 for Class B and Class C
shares, respectively, for the year ended August 31, 1996. Fees incurred under
the distribution plans during the year ended August 31, 1996 were 1.00% of

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.
A contingent deferred sales charge is imposed on shareholder redemptions of
Class C shares in the event of a shareholder redemption within twelve months of
purchases made on or after April 1, 1996. MFD receives all contingent deferred
sales charges. Contingent deferred sales charges imposed during the year ended
August 31, 1996 were $40, $142,038 and $887 for Class A, Class B and Class C
shares, respectively.

effective annual rate of up to 0.15%, up to 0.22% and up to 0.15% attributable
to Class A, Class B and Class C shares, respectively.

(6) LINE OF CREDIT
The Fund entered into an agreement which enables it to participate with other
funds managed by MFS in an unsecured line of credit with a bank which permits
borrowings up to $350 million, collectively. 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 August 31,
1996 was $2,362.
 
(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 written options and 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
do 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. A summary of
obligations under these financial instruments at August 31, 1996, is as follows:

INDEPENDENT AUDITORS' REPORT
 
To the Trustees of MFS Series Trust I and Shareholders of MFS World Asset
Allocation Fund:
 
We have audited the accompanying statement of assets and liabilities of MFS
World Asset Allocation Fund (the Fund) (one of the portfolios constituting MFS
Series Trust I), including the schedule of portfolio investments, as of August
31, 1996, the related statement of operations for the year then ended, and 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 two years in the period then
ended, and for the period from July 22, 1994 (commencement of operations) to
August 31, 1994. 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 securities owned as of
August 31, 1996, by correspondence with the custodian and brokers, or other
appropriate auditing procedures where replies from brokers were not received. 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 referred to
above present fairly, in all material respects, the financial position of MFS
World Asset Allocation Fund at August 31, 1996, the results of its operations
for the year then ended, and 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 two
years in the period then ended, and for the period from July 22, 1994
(commencement of operations) to August 31, 1994, in conformity with generally
accepted accounting principles.

A WORD ABOUT MFS PRODUCTS AND SERVICES

MAKING ADDITIONAL INVESTMENTS AT YOUR CONVENIENCE

There are several easy ways to make additional single investments of at least
$50:

        - send a check with the lower portion of your account statement

        - contact your financial adviser to purchase shares on your behalf

        - wire additional investments through your bank; call us first for
          instructions

MAKING ADDITIONAL INVESTMENTS AUTOMATICALLY

By investing a set amount at regular intervals, over time you will buy more
shares when prices are low, and fewer shares when prices are high. Because
dollar-cost averaging involves periodic purchases regardless of fluctuating
share prices, you should consider your financial ability to continue investing
in periods of low prices.  MFS offers two dollar-cost averaging programs. See
the prospectus for further details. Dollar-cost averaging does not assure a
profit or avoid a loss.

THE AUTOMATIC INVESTMENT PLAN offers a simple way to make regular investments
of at least $50 through automatic withdrawals from your checking account.

THE AUTOMATIC EXCHANGE PLAN automatically exchanges shares from any MFS fund
with $5,000 or more into the same class of shares in up to four other MFS
funds. You choose the amounts of the exchanges (as little as $50) and their
frequency.
