LETTER FROM THE CEO

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%. As of mid-May 2007, it
had returned another 8% and continued to reach new highs. But the Dow's upward
rise has not been without hiccups. After hitting new records in February, the
Dow lost 5.8% between February 20 and March 5, as stocks were sold off around
the globe. As we have said before, markets are 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

Percentages are based on net assets as of 5/31/07.

EXPENSE TABLE

Fund expenses borne by the shareholders during the period, December 1, 2006
through May 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 redemption fees on certain exchanges and redemptions, and (2)
ongoing costs, including management fees; distribution and service (12b-1)
fees; and other fund expenses. This example is intended to help you understand
your ongoing costs (in dollars) of investing in the fund and to compare these
costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the entire period December 1, 2006 through May 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) or redemption fees. Therefore, the second line for each share
class in the table is useful in comparing ongoing costs only, and will not help
you determine the relative total costs of owning different funds. In addition,
if these transactional costs were included, your costs would have been higher.

(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.

SEE NOTES TO FINANCIAL STATEMENTS

Any redemption fees charged by the fund during the 2004 and 2005 fiscal years resulted in a per share impact of less than $0.01.

(a) Annualized.
(b) The fund's net asset value and total return calculation include a non-recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales. The
    non-recurring accrual resulted in an increase in the net asset value of $0.03 per share based on shares outstanding on the
    day the proceeds were recorded. Excluding the effect of this accrual from the ending net asset value per share, Class A,
    Class B, Class C, Class I, Class J, Class R, Class R3, Class 529A, Class 529B and Class 529C total returns for the year
    ended November 30, 2004 would have each been lower by 0.25%.
(d) Per share data are based on average shares outstanding.
(f) Ratios do not reflect reductions from fees paid indirectly.
(g) The per share amount is not in accordance with the net realized and unrealized gain/loss for the period because of the
    timing of sales of fund shares and the per share amount of realized and unrealized gains and losses at such time.
(i) For the period from the class' inception, July 31, 2002 (Classes 529A, 529B, and 529C), December 31, 2002 (Class R),
    October 31, 2003 (Class R3), and April 1, 2005 (Classes R1, R2, R4, and R5) through the stated period end.
(j) The fund's total return calculation includes proceeds received on March 26, 2003 from a non-recurring litigation
    settlement, recorded as a realized gain on investment transactions. The proceeds resulted in an increase in the net asset
    value of less than $0.01 per share based on shares outstanding on the day the proceeds were received. Excluding the effect
    of this payment from the fund's ending net asset value per share, the Class A, Class B, Class C, Class I, Class J, Class R,
    Class 529A, Class 529B and Class 529C total returns for the year ended November 30, 2003 would have been lower by
    approximately 0.07%, 0.08%, 0.08%, 0.07%, 0.09%, 0.08%, 0.08%, 0.09%, and 0.09%, respectively.
(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.

(unaudited)

(1) BUSINESS AND ORGANIZATION

Massachusetts Investors Growth Stock Fund (the fund) 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 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. Short-term instruments with a maturity at issuance of 60 days
or less may be valued at amortized cost, which approximates market value.
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. 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.
Events that occur on a frequent basis after foreign markets close (such as
developments in foreign markets and significant movements in the U.S. markets)
and prior to the determination of the fund's net asset value may be deemed to
have a material affect on the value of securities traded in foreign markets.
Accordingly, the fund's foreign equity securities may often be valued at fair
value. 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.

SECURITY LOANS - State Street Bank and Trust Company ("State Street") and
JPMorgan Chase and Co. ("Chase"), as lending agents, may loan the securities of
the fund to certain qualified institutions (the "Borrowers") approved by the
fund. The loans are collateralized at all times by cash and/or U.S. Treasury
securities in an amount at least equal to the market value of the securities
loaned. Security lending activity through Chase is further collateralized by an
irrevocable standby letter of credit. State Street and Chase provide the fund
with indemnification against Borrower default. The fund bears the risk of loss
with respect to the investment of cash collateral. On loans collateralized by
cash, the cash collateral is invested in a money market fund or short-term
securities. A portion of the income generated upon investment of the collateral
is remitted to the Borrowers, and the remainder is allocated between the fund
and the lending agents. On loans collateralized by U.S. Treasury securities, a
fee is received from the Borrower, and is allocated between the fund and the
lending agents. Net income from securities lending is included in interest
income on the Statement of Operations. The dividend and interest income earned
on the securities loaned is accounted for in the same manner as other dividend
and interest income.

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.

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. 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 May 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 wash sale loss deferrals.

The fund declared no distributions for the year ended November 30, 2006.

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

          AS OF 5/31/07

          Cost of investments                         $5,323,313,141

          Net unrealized appreciation (depreciation)     284,903,960

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

As of November 30, 2006, the fund had capital loss carryforwards available to
offset future realized gains. Such losses expire as follows:

              11/30/09                           $(2,112,952,292)
              11/30/10                            (2,299,721,199)
              --------------------------------------------------
                                                 $(4,412,673,491)

In June 2006, FASB Interpretation No. 48, Accounting for Uncertainty in Income
Taxes (the "Interpretation") was issued, and is effective for fiscal years
beginning after December 15, 2006 and is to be applied to all open tax years as
of the effective date. On December 22, 2006, the SEC delayed the implementation
of the Interpretation for regulated investment companies for an additional six
months. This Interpretation prescribes a minimum threshold for financial
statement recognition of the benefit of a tax position taken or expected to be
taken in a tax return, and requires certain expanded disclosures. Management
has evaluated the application of the Interpretation to the fund, and has
determined that there is no impact resulting from the adoption of this
Interpretation on the fund's financial statements.

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 daily net
assets 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 an annual rate of 0.33% of the fund's average daily net assets.

DISTRIBUTOR - MFS Fund Distributors, Inc. (MFD), a wholly-owned subsidiary of
MFS, as distributor, received $74,635 and $980 for the six months ended May 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.

(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
    May 31, 2007 based on each class' average daily net assets. Assets attributable to Class A shares sold prior to
    March 1, 1991 are subject to a service fee of 0.15% annually. 0.10% of the Class 529A distribution fee is
    currently being paid by the fund. Payment of the remaining 0.15% of the Class 529A distribution fee is not yet
    in effect and will be implemented on such date as the fund's Board of Trustees may determine.
(f) Includes fees that MFD pays to financial intermediaries and for services rendered as the fund's agent company
    in Japan.


Certain Class A, Class C and Class 529C shares are subject to a contingent
deferred sales charge in the event of a shareholder redemption within 12 months
of purchase. Class B and Class 529B 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 May 31, 2007, were as follows:

                                                          AMOUNT

              Class 529C                                      --

The fund has entered into and may from time to time enter into contracts with
program managers and other parties which administer the tuition programs
through which an investment in the fund's 529 share classes is made. The fund
has entered into an agreement with MFD pursuant to which MFD receives an annual
fee of up to 0.35% of the average daily net assets attributable to each 529
share class. The fee is based on average daily net assets and is currently
established at 0.25% annually of average daily net assets of the fund's 529
share classes. The fee may only be increased with the approval of the Board of
Trustees who oversees the fund. The services provided by MFD, or a third party
with which MFD contracts, include recordkeeping and tax reporting and account
services, as well as services designed to maintain the program's compliance
with the Internal Revenue Code and other regulatory requirements. Program
manager fees for the six months ended May 31, 2007, were as follows:

                                                          AMOUNT

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 May 31, 2007, the fee was $1,670,619,
which equated to 0.0582% 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 May 31, 2007, these
out-of-pocket expenses, sub-accounting and other shareholder servicing costs
amounted to $3,389,709. 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 calendar year average net assets. The fund's annual
fixed amount is $17,500.

The administrative services fee incurred for the six months ended May 31, 2007
was equivalent to an annual effective rate of 0.0106% of the fund's average
daily net assets.

In addition to the administrative services provided by MFS to the fund as
described above, MFS is responsible for providing certain retirement plan
administration and services with respect to certain shares. These services
include various administrative, recordkeeping, and communication/educational
services with respect to the retirement plans which invest in these shares, and
may be provided directly by MFS or by a third party. MFS may subsequently pay
all, or a portion, of the retirement plan administration and services fee to
affiliated or unaffiliated third parties. For the six months ended May 31,
2007, the fund paid MFS an annual retirement plan administration and services
fee up to the following annual percentage rates of each class' average daily
net assets:

(g) Prior to April 1, 2007, MFS had agreed in writing to waive a portion of
    the retirement plan administration and services fee equal to 0.10% for
    Class R1, 0.15% for Class R2, and 0.10% for Class R3 shares. This
    agreement was discontinued on March 31, 2007. On April 1, 2007, the annual
    retirement plan administration and services fee for Class R1, Class R2,
    and Class R3 shares was lowered to 0.35%, 0.25%, and 0.15%, respectively.
    For the six months ended May 31, 2007, the waiver amounted to $4,228 and
    is reflected as a reduction of total expenses in the Statement of
    Operations.

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 $6,148. The fund also has an
unfunded retirement benefit deferral plan for certain independent trustees
which resulted in an expense of $10,414. Both amounts are included in
independent trustees' compensation for the six months ended May 31, 2007. The
liability for deferred retirement benefits payable to certain independent
trustees under both plans amounted to $225,471 at May 31, 2007, and is included
in payable for independent trustees' compensation.

DEFERRED TRUSTEE COMPENSATION - Under a Deferred Compensation Plan (the Plan)
independent trustees previously were allowed to elect to defer receipt of all
or a portion of their annual compensation. Trustees are no longer allowed to
defer compensation under the Plan. Amounts previously deferred are treated as
though equivalent dollar amounts had been invested in shares of certain MFS
funds selected by the trustee. Deferred amounts represent an unsecured
obligation of the fund until distributed in accordance with the Plan. Included
in other assets and payable for independent trustees' compensation is $75,285
of deferred 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 May 31, 2007, the fee paid to Tarantino LLC
was $22,547. MFS has agreed to reimburse the fund for a portion of the payments
made by the funds to Tarantino LLC in the amount of $14,390, 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.

(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 May 31, 2007, the fund's commitment fee and interest expense were $17,131
and $0, respectively, and are included in miscellaneous expense on the
Statement of Operations.

(7) SUBSEQUENT EVENT

On February 27, 2007, the trustees of the fund approved the proposed Agreement
and Plan of Reorganization, whereby MFS Growth Opportunities Fund would be
reorganized into Massachusetts Investors Growth Stock Fund. The Agreement and
Plan of Reorganization provides for the transfer of the assets of the MFS
Growth Opportunities Fund to the Massachusetts Investors Growth Stock Fund and
the assumption by the Massachusetts Investors Growth Stock Fund of the
liabilities of the MFS Growth Opportunities Fund in exchange solely for shares
of beneficial interest in the Massachusetts Investors Growth Stock Fund.
Immediately following the transfer, the Massachusetts Investors Growth Stock
Fund shares received by the MFS Growth Opportunities Fund will be distributed
to shareholders, pro rata, and the MFS Growth Opportunities Fund will be
liquidated and terminated. The reorganization occurred on June 22, 2007.

Effective June 15, 2007, Class J shares of the fund were terminated.
