LETTER TO SHAREHOLDERS


Dear Shareholders:

The municipal  bond market has recovered  handsomely  from 1994's sharp setback.
Yields of  longer-term  high-grade  bonds have  declined  about 75 basis  points
(0.75%)  from the end of 1994 through  August 31,  1995,  as the bond market has
responded to the economy's slowing growth rate consistent with diminishing fears
of inflation.  Intense price competition,  restrained wage growth and government
downsizing have contributed to the positive outlook for inflation.  This outlook
has also been improved by prospects for meaningful federal deficit reduction and
the recent recovery of the dollar in currency markets. For the year ended August
31, 1995,  Class A shares of the Fund  provided a total return of +7.31%,  while
Class B shares had a total return of +6.35%.  Both of these  figures  assume the
reinvestment  of  distributions  but exclude  the effects of any sales  charges.
Complete performance information for the Fund is provided on pages four and five
of this report.

Economic Outlook

Moderate,  but  sustainable  growth  appears to be the  hallmark of the economic
expansion's  fifth year. After slowing earlier in the summer,  consumer spending
and  homebuying  were showing  renewed  strength by August 31, while  businesses
continued to work off excess  inventories and reduce factory output.  Meanwhile,
overseas economies,  particularly those of Germany and Japan, have not recovered
as  expected,  limiting  U.S.  export  growth.  However,  we believe the Federal
Reserve Board's  consistent and, so far,  successful  efforts to fight inflation
seem to be giving  consumers and businesses  enough  confidence to help maintain
2 1/2% to 3% real (adjusted for inflation) growth in gross domestic  product, at
least through 1995.

Interest Rates

Although the Federal Reserve implemented a one-quarter percentage point decrease
in short-term  interest rates in July, the effects of its seven rate  increases,
which began in early 1994 and ended in  February  of this year,  are still being
felt  throughout the economy.  While there have been some increases in commodity
prices,  companies  have not been able to pass along most of those higher costs,
partly  because of the need to keep fighting for market share,  but also because
wages and benefits of U.S.  workers are still  growing at a pace that is near or
perhaps below the inflation rate,  limiting consumer buying power. At the end of
July, the nation's  employment  cost index had risen at a rate of just 2.8% over
the previous year, helping to contain cost pressures. At the same time, however,
the bond markets have apparently  become  convinced that economic growth will be
contained  for the near  future and have  allowed  long-term  interest  rates to
decline slightly. Although previous monetary easing by the Federal Reserve has


                                                                               1

LETTER TO SHAREHOLDERS - continued

been followed by additional rate reductions,  prospects for further decreases in
the current  environment are uncertain.  Still, with long-term  government bonds
yielding  approximately  6.6%, in an environment of 2 1/2% to 3% inflation, real
rates of return in the fixed-income markets remain relatively attractive.

Municipal Bond Market

While  municipal bonds have provided  impressive  returns so far this year, they
have  significantly  underperformed  many  segments of the taxable  bond market.
Indeed,  for the six-month  period ended August 31, yields of  longer-term  U.S.
Treasuries  declined by about 85 basis points (0.85%),  while  municipal  yields
declined by a meager 10 basis points  (0.10%).  Over this  period,  the ratio of
long-term,  AAA-rated  municipal yields to comparable U.S.  Treasury yields rose
from 80% to 87%,  the  highest  level for this ratio  since  late 1993,  leaving
municipals very  attractively  priced (although  principal value and interest on
Treasury securities are guaranteed by the U.S. government if held to maturity).

      The municipal  bond market's  underperformance  seemed to begin soon after
the media  began to focus on  various  proposals  for  radical  tax  reform.  If
enacted, a substantial  reduction in federal income tax rates, some type of flat
tax and/or the loss of municipal bonds' unique tax-exempt status would certainly
have negative  implications  for valuations of outstanding  municipal bonds. The
unresolved  status of the Orange County,  California  bankruptcy  also depressed
market  psychology,  while the  soaring  equity  markets  have  offered a strong
challenge to all fixed-income investments.  Thus, while the supply of new issues
is down 25% from the corresponding  period in 1994, and despite the continuation
of a heavy  volume of bond  calls,  demand  for  long-term  municipals  has been
disappointing  this  year,  leading to the  dramatic  increase  in yield  ratios
between the tax-exempt and taxable markets.

      For the long-term  municipal bond  investor,  we believe the current yield
ratios  may  provide  an   attractive   opportunity,   in  spite  of   near-term
uncertainties. Serious consideration of tax reform, for example, is probably two
years off, in our opinion,  and a truly radical  overhaul of the current  system
still seems politically unlikely.  At today's ratios,  municipals have seemingly
already  adjusted  for a more  moderate  version  of  tax  reform,  such  as the
imposition of lower marginal rates as part of a flat-tax  system.  As for Orange
County,  the market  clearly  recognized  that  situation as a unique,  isolated
instance of fiscal  irresponsibility.  We believe the overall  fiscal  health of
state and local  governments is its strongest in years. As for the stock market,
clearly it is not going to go up forever.  Thus, its strength as a competitor to
municipal  bonds seems likely to weaken at some point.

Portfolio Performance and Strategy 

Total  returns  for the  Fund's  Class A and Class B shares  for the year  ended
August  31,  1995  underperformed  the  +8.86%  return  of the  Lehman  Brothers
Municipal Bond Index (the Lehman Index),  an unmanaged  index of municipal bonds
rated Baa or better.  The performance of Class A shares was nearly identical to,
while  Class B shares  slightly  underperformed  the  average  return  of +7.34%
reported by Lipper Analytical Services,  Inc. (an independent firm which reports
mutual fund performance) for other municipal bond funds with similar  investment
objectives and policies.  In the general  municipal  debt  category,  the Fund's
Class A shares  ranked  109th out of 211 funds for the past year.  Nevertheless,
over longer time periods,  the Fund has one of the better performance records in
its peer group;  according to Lipper,  the Fund's Class A shares ranked 24th out
of 99 funds in its general  municipal debt category for the past five years, and
13th out of 54 fund for the past 10 years.  Also,  the Fund would have performed
better,  compared to the Lehman Index,  had it  restructured  itself earlier and
more  aggressively to take advantage of this year's trend of declining  interest
rates.

      Given  our  generally  favorable  outlook  for the bond  market,  the Fund
remains  well-invested  in long-term  maturities  seeking to  participate in the
price  appreciation  resulting from declining  interest  rates.  In an effort to
maximize  performance and minimize call risk,  about 33% of the Fund is invested
in  bonds  that are  non-callable.  Finally,  reflecting  the  fact  that  yield
differentials  between qualities remain  historically  narrow,  the Fund remains
predominantly invested in high-quality  securities;  currently nearly 70% of the
Fund is invested in  securities  rated by  Standard & Poor's  Corporation  AA or
higher.

      We  appreciate  your support and welcome any questions or comments you may
have.


Respectfully,

/s/ A. Keith Brodkin                           /s/ Robert A. Dennis

In the above table,  we have  included the average  annual total  returns of all
general  municipal debt funds (including the Fund) tracked by Lipper  Analytical
Services,  Inc. for the applicable  time periods (211,  117, 99 and 54 funds for
the 1-, 3-, 5- and 10-year periods ended August 31, 1995, 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.

NOTES TO FINANCIAL STATEMENTS

(1) Business and Organization

MFS Municipal  Bond Fund (the Fund) is a diversified  series of MFS Series Trust
IV (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

Investment Valuations - Debt securities (other than short-term obligations which
mature in 60 days or less),  including listed issues, 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.  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.
Securities  for which there are no such  quotations or valuations  are valued at
fair value as determined in good faith by or at the direction of the Trustees.

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 purchased 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  securities  transferred  to  ensure  that the  value,
including accrued interest, of the securities under each repurchase agreement is
greater than amounts owed to the Fund under each such repurchase agreement.

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
security  purchased by the Fund.  The Fund, as writer of an option,  may have no
control  over  whether the  underlying  security 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.


22


<PAGE>


NOTES TO FINANCIAL STATEMENTS - continued

Futures  Contracts - The Fund may enter into futures  contracts  for the delayed
delivery of securities or contracts based on financial  indices at a fixed price
on a future date.  In entering such  contracts,  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  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.
Should interest rates or securities prices move  unexpectedly,  the Fund may not
achieve the  anticipated  benefits of the  futures  contracts  and may realize a
loss.

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 financial  statement and
tax reporting purposes as required by federal income tax regulations.

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 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.

Distributions  paid  by the  Fund  from  net  interest  received  on  tax-exempt
municipal  bonds are not includable by  shareholders as gross income for federal
income tax purposes because the Fund intends to meet certain requirements of the
Code applicable to regulated investment companies, which will enable the Fund to
pay exempt-interest  dividends.  The portion of such interest, if any, earned on
private  activity  bonds  issued  after  August  7,  1986  may be  considered  a
tax-preference item to shareholders.  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 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.


                                                                              23


<PAGE>


NOTES TO FINANCIAL STATEMENTS - continued

During  the year  ended  August  31,  1995,  $1,335,235  was  reclassified  from
accumulated   net  investment   income  to  accumulated  net  realized  gain  on
investments due to differences between book and tax accounting.  This change had
no effect on the net assets or net asset value per share.

At August 31, 1995, the accumulated  distributions  exceeded book income because
of differences in book and tax accounting for dividends declared but not paid at
year end.

At August 31, 1995,  the Fund,  for federal  income tax purposes,  had a capital
loss  carryforward of $16,113,077,  which may be applied against any net taxable
realized gains of each  succeeding  year until the earlier of its utilization or
expiration on August 31, 2002 ($5,959,343) and August 31, 2003 ($10,153,734).

Multiple Classes of Shares of Beneficial  Interest - The Fund offers Class A and
Class B shares. The two 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 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
0.19% of average daily net assets and 3.59% of investment income.

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 of its  independent  Trustees  and Mr.  Bailey.  Included  in  Trustees'
compensation  is a net  periodic  pension  expense of $21,347 for the year ended
August 31, 1995.

Distributor - MFD, a wholly owned  subsidiary of MFS, as  distributor,  received
$329,416  as its  portion of the sales  charge on sales of Class A shares of the
Fund. The Trustees have adopted a distribution  plan relating  solely to Class B
shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows:

The Class B 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 shares. The service fee
is not charged on Class B shares held over one year.  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 shares.  The service fee is intended to be
additional consideration for services rendered by the dealer with

NOTES TO FINANCIAL STATEMENTS - continued

respect  to Class B  shares.  MFD  retains  the  service  fee for  accounts  not
attributable  to a  securities  dealer,  which  amounted to $106,468 for Class B
shares for the year ended August 31, 1995. Fees incurred under the  distribution
plan  during the year  ended  August  31,  1995 were 0.88% of average  daily net
assets attributable to Class B shares on an annualized basis.

A contingent  deferred  sales charge is imposed on  shareholder  redemptions  of
Class  A  shares,  on  purchases  of $1  million  or  more,  in the  event  of a
shareholder  redemption  within twelve months  following the share  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 August 31, 1995 were $6,621 and $221,978
for Class A and Class B 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  average  daily  net  assets  of each  class of  shares at an
effective annual rate of up to 0.15% and up to 0.22% attributable to Class A and
Class B shares, respectively.

(4) Portfolio Securities

Purchases  and sales of  investments,  other  than U.S.  government  securities,
purchased   option   transactions   and   short-term   obligations,   aggregated
$1,725,547,749 and $1,887,039,954, 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                                                  $ 1,796,032,798

(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,
1995 was $34,272.


(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. These financial  instruments  include futures 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.  A summary of
obligations under these financial instruments at August 31, 1995, is as follows:

The Fund  also  invests  in  indexed  securities  whose  value  may be linked to
interest  rates  or  other   financial   indicators.   Indexed   securities  are
fixed-income   securities   whose   proceeds  at   maturity   (principal-indexed
securities)  or  interest  rates  (coupon-indexed   securities)  rise  and  fall
according to the change in one or more specified underlying instruments. Indexed
securities  may be more  volatile than the  underlying  instrument  itself.  The
following is a summary of such securities held at August 31, 1995:

INDEPENDENT AUDITORS' REPORT

To the Trustees of MFS Series Trust IV and Shareholders
of MFS Municipal Bond Fund:

We have audited the accompanying statement of assets and liabilities,  including
the  portfolio of  investments,  of MFS  Municipal  Bond Fund (one of the series
constituting  MFS Series Trust IV) as of August 31, 1995, the related  statement
of  operations  for the year then ended,  the statement of changes in net assets
for the year then ended, the ten months ended August 31, 1994 and the year ended
October 31,  1993,  and the  financial  highlights  for each of the years in the
ten-year period ended August 31, 1995. 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
August 31, 1995 by correspondence  with the custodian and brokers. 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,  such  financial  statements  and financial  highlights  present
fairly, in all material  respects,  the financial position of MFS Municipal Bond
Fund at August 31, 1995, the results of its  operations,  the changes in its net
assets,  and its  financial  highlights  for the  respective  stated  periods in
conformity with generally accepted accounting principles.
