Letter to Shareholders

Dear Shareholders:

Although  interest  rates  backed up  somewhat  during  February  as an apparent
firming of the economy diminished investors' hopes of further monetary easing by
the Federal Reserve Board, the municipal market performed very well over the six
months ended  February 29, 1996.  Long-term,  high-grade  municipal  bond yields
declined by about 40 basis points (0.40%), compared to a drop of 20 basis points
(0.20%) by long-term U.S.  Treasuries over the same period  (although  principal
value and interest on Treasury  securities are guaranteed by the U.S. government
if held to maturity).  During this period, Class A shares of the Fund provided a
total return of 5.33%, while Class B shares had a total return of 4.74%. 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 page five of this report.

Economic Environment

We believe the U.S.  economy will continue to grow in 1996 - although  "subdued"
may be the best way to describe this growth.  One factor holding growth in check
is the continued  sluggishness of the consumer  sector,  an area that represents
approximately  two-thirds of the economy.  Going into this year,  consumers have
been  left in a  somewhat  weakened  position,  due in part  to an  increase  in
consumer  installment  debt of some 30% over the past two years. A second reason
for the  economy's  weakness  is the "lag  effect" of  increases  in  short-term
interest rates by the Federal Reserve in 1994 and into 1995. This lag effect can
last up to two years, although a series of reductions in short-term rates by the
Fed,  which  began late last year,  could  provide  some  support to the economy
through  1996. A third reason for weakness is the ongoing  economic  doldrums in
Europe and Japan,  important markets for U.S. exports. Here again, we are seeing
a few signs,  particularly  in Japan,  of modest  recoveries  that could lead to
improved  prospects for U.S.  exporters.  Also, we believe lower  interest rates
will  give a boost to the U.S.  housing  market,  an  important  segment  of the
economy since it also affects such  industries as major  appliances,  furniture,
and building-supply companies. Finally, although the first few weeks of 1996 saw
some signs of inflationary  pressures,  caused primarily by rising energy prices
and followed by an upward  movement in gold,  we believe  inflation  will remain
under control this year, due mainly to the subdued level of economic growth.

Interest Rates

Persistent  signs of economic  weakness led to decreases in short-term  interest
rates by the Federal  Reserve in late 1995 and early 1996 and, we believe,  will
lead to some additional  reductions as the year progresses.  In the beginning of
the year,  bond markets  were  trading in a narrow  range as  investors  shifted
between  concern about the lack of a budget  resolution in Washington  and hopes
that sluggish  economic  reports and low inflation  might lead to lower interest
rates.

                                                                               1
<PAGE>

Letter to Shareholders - continued

In the recent  trading  period  not  covered by this  report,  the  fixed-income
markets  have  reacted to  conflicting  signals  regarding  the  strength of the
economy with more volatile trading patterns marked by an upward bias in interest
rates.  However, we believe the fundamentals of moderate economic growth and low
inflation will continue to benefit  long-term  investors.  Barring an unexpected
shock, we anticipate that the still-cheap dollar, low interest rates, and strong
total  employment  will likely cushion the economy from a sharp decline.  Still,
given the subdued state of the economy, we believe that some additional interest
rate reductions by the Fed are possible,  although their timing and magnitude is
uncertain, and that bonds continue to represent good value.

Municipal Bond Market

Supply in the new-issue  municipal bond market continued to be manageable during
the past six  months.  Volume in 1995  declined  5% from the  previous  year and
represented  only  slightly  more than half the issuance of 1993's record level.
Barring a sharp further decline in interest  rates,  issuance is not expected to
increase significantly during 1996. Besides generally favorable technicals,  the
municipal market's  outperformance relative to Treasuries can also be attributed
to an apparent  diminishing of investors' fears concerning major tax reform.  As
the "flat-tax" concept became an issue during the early presidential  primaries,
it became clear that there was significant  political  opposition to some of its
controversial elements, such as the elimination of popular deductions and making
all investment income tax exempt.  With the flat-tax concept facing  significant
questions of both fairness and revenue neutrality,  investors began to feel that
municipals would not lose their unique tax-exempt status and that any future tax
reform would be incremental,  practical,  and moderate.  Accordingly,  the yield
ratio of 30-year  AAA-rated  municipals to  Treasuries  declined from 87% to 84%
over the six-month period.

Portfolio

Performance and Strategy The total return of 5.33% for the Fund's Class A shares
for the six-month  period ended February 29, 1996 exceeded both the 4.87% return
of the Lehman  Brothers  Municipal Bond Index (the Lehman  Index),  an unmanaged
index of  municipal  bonds  rated Baa or better,  and the 4.98%  average  return
reported by Lipper Analytical Services,  Inc. (an independent firm which reports
mutual  fund  performance)  for its general  municipal  debt  category.  Class B
shares,  meanwhile,  slightly  underperformed  these indices.  Although the Fund
underperformed  during the first two months of 1996, its above-average  interest
rate sensitivity  contributed to its favorable results over the entire six-month
period.  Since  there  have  been  no  significant  changes  in  sector  trading
relationships,   performance  results  have  been  predominantly  attributed  to
decisions affecting portfolio duration.

Letter to Shareholders - continued

     While we will be closely monitoring economic developments, the Fund remains
structured  in a way that we  believe  will allow it to  perform  well  during a
period of stable to declining interest rates. More than 30% of the Fund's assets
are invested in long-term,  non-callable  bonds,  and much of the balance of the
portfolio also consists of bonds that are structured to benefit from a declining
interest rate environment.

     Yield differentials  between high- and low-quality bonds remain very narrow
despite the fact that several  sectors of municipal  finance face serious future
challenges.  General  obligation  bonds,  for  example,  would  be  affected  by
declining federal aid for local programs; issuers of electric revenue bonds face
an environment of increasing competition;  and hospitals struggle in an industry
marked by continuing cost  pressures.  Thus, we believe the Fund's 70% weighting
of  securities  rated AA or higher by Standard & Poor's  Corporation  to be very
appropriate.

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

Respectfully,

Portfolio Manager Profile

A graduate of  Massachusetts  Institute  of  Technology  and its Sloan School of
Management,  Robert  Dennis  began his career at MFS in 1980 and was promoted to
Vice  President  -  Investments  in 1983.  In 1986,  he was  named  Senior  Vice
President.  He has been the Portfolio  Manager of MFS Municipal  Bond Fund since
1984. Mr. Dennis is a Chartered Financial Analyst (C.F.A.).


Objective and Policies

The Fund's investment  objective is to provide as high a level of current income
exempt from  federal  income  taxes as is  considered  consistent  with  prudent
investing while seeking  protection of investors'  capital.  A portion of income
may be subject to state, federal, and/or alternative minimum tax. Capital gains,
if  any,  are  subject  to a  capital  gains  tax.  The  Fund  normally  invests
substantially  all of its assets (i.e.,  at least 80%) in debt securities in the
highest  three  grades of  Standard & Poor's  Corporation  or Moody's  Investors
Service,  Inc. (and  comparable  unrated  securities),  the interest on which is
exempt from federal income tax. As a temporary defensive measure during times of
adverse  market  conditions,  up to 50% of the Fund's  assets may be invested in
obligations  issued or  guaranteed  by the U.S.  government  or its  agencies or
instrumentalities,  commercial  paper,  obligations of larger banks or cash. The
Fund may enter into options and futures  transactions and purchase securities on
a "when-issued" basis.

Notes to Financial Statements (Unaudited)

(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.

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.
Investments in equity-indexed  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 the cash is being
invested. 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.
Interest  payments  received  in  additional  securities  are  recorded  on  the
ex-interest date in an amount equal to the value of the security on such date.

Fees Paid  Indirectly -- The Fund's  custodian bank  calculates its fee based on
the Fund's  average  daily net  assets.  The fee is reduced  according  to a fee
arrangement,  which  provides for custody fees to be reduced  based on a formula

Notes to Financial Statements (Unaudited) -- continued

developed to measure the value of cash deposited with the custodian by the Fund.
This amount is shown as a reduction of expenses on the Statement of Operations.

Tax  Matters  and  Distributions  -- The  Fund's  policy is to  comply  with the
provisions  of the  Internal  Revenue  Code (the Code)  applicable  to regulated
investment  companies and to distribute to  shareholders  all of its 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.

At August 31, 1995,  the Fund,  for federal  income tax purposes,  had a capital
loss carry-forward 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 both 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.

                                                                              23

(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 0.21% 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 $11,968 for the period ended
February 29, 1996.

Distributor -- MFD, a wholly owned  subsidiary of MFS, as distributor,  received
$159,663  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  currently  suspended  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 respect
to Class B shares.  MFD retains the service fee for accounts not attributable to
a  securities  dealer,  which  amounted  to $0 for Class B shares for the period
ended February 29, 1996.  Fees incurred under the  distribution  plan during the
period  ended  February  29,  1996  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  12  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 period ended February 29, 1996 were $118 and $179,716
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
$815,537,114 and $862,926,672, 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                                                   $1,744,459,300

(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 period ended February
29, 1996 was $25,069.

(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 February  29,  1996,  is as
follows:

Futures Contracts
                                                                      Unrealized

March 1996            48 Municipal Bonds             Long                 10,500
                                                                         -------
                                                                         $23,625
                                                                         -------

At February 29, 1996,  the Fund had sufficient  cash and/or  securities to cover
margin requirements on open futures contracts.

The Fund  also  invests  in  indexed  securities  whose  value  may be linked to
interest rates,  indices or other financial  indicators.  Indexed securities are
fixed-income  securities whose 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
February 29, 1996:

(8) Restricted Securities

The Fund may invest not more than 15% of its total  assets in  securities  which
are subject to legal or  contractual  restrictions  on resale.  At February  29,
1996, the Fund owned the following restricted securities  (constituting 0.70% of
total  assets)  which may not be publicly  sold without  registration  under the
Securities  Act of 1933.  The Fund does not have the  right to demand  that such
securities  be  registered.  The  value of these  securities  is  determined  by
valuations supplied by a pricing service or brokers.
