Supplement to the Prospectus and Statement of Additional Information dated
January 1, 1997 as revised April 10, 1997.
The following information should be read in conjunction with the Fund's
Prospectus and Statement of Additional Information ("SAI"), dated January 1,
1997 as revised April 10, 1997, and contains a description of Class I shares.
Class I shares are available for purchase only by certain investors as
described under the caption "Eligible Purchasers" below.
EXPENSE SUMMARY

Maximum Initial Sales Charge Imposed on Purchases of Fund

of original purchase price or redemption proceeds, as applicable). None

(1) "Other Expenses" is based on Class A expenses incurred during the fiscal
period ended August 31, 1996.
(2) The Fund has an expense offset arrangement which reduces the Fund's
custodian fee based upon the amount of cash maintained by the Fund with its
custodian and dividend disbursing agent, and may enter into other
such arrangements and directed brokerage arrangements (which would
also have the effect of reducing the Fund's expenses). Any such fee
reductions are not reflected under "Other Expenses."
(3) The Adviser has agreed to bear the Fund's expenses, subject to
reimbursement by the Fund, such that "Other Expenses" do not exceed 0.50%
per annum of its average daily net assets during the currect fiscal year.
Otherwise, "Other Expenses" and "Total Operating Expenses" would be 1.34%
and 2.09%, respectively. See "Other Information" below.
Example of Expenses
An investor would pay the following dollar amounts of expenses on a $1,000
investment in Class I shares of the Fund, assuming (a) a 5% annual return and
(b) redemption at the end of each of the time periods indicated:
Period Class I
1 year.................... $13
3 years................... 40
The purpose of the expense table above is to assist investors in
understanding the various costs and expenses that a shareholder of the Fund will
bear directly or indirectly. A more complete description of the Fund's
management fee is set forth under the caption "Management of the Fund" in the
Prospectus.
The "Example" set forth above should not be considered a representation of past
or future expenses of the Fund; actual expenses may be greater or less than
those shown.
ELIGIBLE PURCHASERS
Class I shares are available for purchase only by the following purchasers
("Eligible Purchasers"):
(i) certain retirement plans established for the benefit of employees of
Massachusetts Financial Services Company ("MFS"), the Fund's investment
adviser, and employees of MFS' affiliates;
<PAGE>
(ii) any fund distributed by MFS Fund Distributors, Inc. ("MFD"), the Fund's
distributor, if the fund seeks to achieve its investment objective by
investing primarily in shares of the Fund and other funds distributed by
MFD;
(iii)any retirement plan, endowment or foundation which (a) purchases shares
directly through MFD (rather than through a third party broker or dealer or
other financial intermediary); (b) has, at the time of purchase of Class I
shares, aggregate assets of at least $100 million; and (c) invests at least
$10 million in Class I shares of the Fund either alone or in combination
with investments in Class I shares of other MFS funds distributed by MFD
(additional investments may be made in any amount); provided that MFD may
accept purchases from smaller plans, endowments or foundations or in
smaller amounts if it believes, in its sole discretion, that such entity's
aggregate assets will equal or exceed $100 million, or that such entity
will make additional investments which will cause its total investment to
equal or exceed $10 million, within a reasonable period of time; and
(iv) bank trust departments which initially invest, on behalf of their trust
clients, at least $100,000 in Class I shares of the Fund (additional
investments may be made in any amount); provided that MFD may accept
smaller initial purchases if it believes, in its sole discretion, that the
bank trust department will make additional investments, on behalf of its
trust clients, which will cause its total investment to equal or exceed
$100,000 within a reasonable period of time.
In no event will the Fund, MFS, MFD or any of their affiliates pay any sales
commissions or compensation to any third party in connection with the sale of
Class I shares; the payment of any such sales commission or compensation would,
under the Fund's policies, disqualify the purchaser as an eligible investor in
Class I shares.
SHARE CLASSES OFFERED BY THE FUND
Four classes of shares of the Fund currently are offered for sale, Class A
shares, Class B shares, Class C shares and Class I shares. Class I shares are
available for purchase only by Eligible Purchasers, as defined above, and are
described in this Supplement. Class A shares, Class B shares and Class C shares
are described in the Fund's Prospectus and are available for purchase by the
general public.
Class A shares are offered at net asset value plus an initial sales charge
up to a maximum of 5.75% of the offering price (or a contingent deferred sales
charge (a "CDSC") of 1.00% upon redemption during the first year in the case of
purchases of $1 million or more and certain purchases by retirement plans), and
are subject to an annual distribution fee and service fee up to a maximum of
0.35% per annum. Class B shares are offered at net asset value without an
initial sales charge but are subject to a CDSC upon redemption (declining from
4.00% during the first year to 0% after six years) and an annual distribution
fee and service fee up to a maximum of 1.00% per annum; Class B shares convert
to Class A shares approximately eight years after purchase. Class C shares are
offered at net asset value without an initial sales charge but are subject to a
1.00% CDSC upon redemption during the first year and an annual distribution fee
and service fee up to a maximum of 1.00% per annum. Class I shares are offered
at net asset value without an initial sales charge or CDSC and are not subject
to a distribution or service fee. Class C shares and Class I shares do not
convert to any other class of shares of the Fund.
OTHER INFORMATION
Eligible Purchasers may purchase Class I shares only directly through MFD.
Eligible Purchasers may exchange Class I shares of the Fund for Class I shares
of any other MFS Fund available for purchase by such Eligible Purchasers at
their net asset value (if available for sale), and may exchange Class I shares
of the Fund for shares of the MFS Money Market Fund (if available for sale), and
may redeem Class I shares of the Fund at net asset value. Distributions paid by
the Fund with respect to Class I shares generally will be greater than those
paid with respect to Class A shares, Class B shares and Class C shares because
expenses attributable to Class A shares, Class B shares and Class C shares
generally will be higher.
Subject to termination or revision at the sole discretion of MFS, MFS has
agreed to bear the Fund's expenses such that the Fund's "Other Expenses," which
are defined to include all Fund expenses except for management fees and class
specific expenses, do not exceed 0.50% per annum of its average daily net assets
(the "Maximum Percentage"). The obligation of MFS to bear these expenses
terminates on the last day of the Fund's fiscal year in which the Fund's "Other
Expenses" are less than or equal to the Maximum Percentage. The payments made by
MFS on behalf of the Fund under this arrangement are subject to reimbursement by
the Fund to MFS, which will be accomplished by the payment of an expense
reimbursement fee by the Fund to MFS computed and paid monthly at a percentage
of its average daily net assets for its then current fiscal year, with a
limitation that immediately after such payment the Fund's "Other Expenses" will
not exceed the Maximum Percentage. This expense reimbursement by the Fund to MFS
terminates on the earlier of the date on which payments made by the Fund equal
the prior payment of such reimbursable expenses by MFS or April 10, 2000.
The date of this Supplement is April 10, 1997
