                               Chairman's Message

DEAR FELLOW SHAREHOLDERS:

The stock market has certainly put on a show since the start of the year. Stocks
began 1997 on the high wires, bolstered by a near-perfect "Goldilocks" economy -
not too hot, not too cold. In almost a straight shot,  the Dow Jones  Industrial
Average  soared  through the 7000 level for the first time in early March.  Just
days later,  stocks lost their  footing and staged a  month-long  free-fall in a
nervous  reaction to rising  interest rates and data that showed the economy was
picking up steam.  Stocks gave back all of their year's gain and suffered  their
worst decline  since 1990 during this period.  No sooner had real fears begun to
beset investors than they were gone, erased in a euphoric rally caused by strong
earnings  and no signs of  inflation.  By the end of May,  the Dow had  risen by
14.6% and the  broader  Standard & Poor's 500 Stock  Index by 15.4% - levels not
many  thought  the  market  would  reach  all year,  let  alone in five  months.
Bondholders  have not  enjoyed  the same  bounty,  as the bond market has mostly
stayed  worried  about the  strength of the economy,  the  direction of interest
rates, and the Federal Reserve's next moves to pre-empt inflation. 

   But the stock market's  latest advance has amazed many analysts and left them
pondering their valuation models, since the market is now more expensive than it
has been in  decades.  It's  impossible  to know  what will  happen  next in the
markets. But whether it's another strong move forward or a retreat, we recommend
keeping a long-term perspective, rather than over-focusing on the market's daily
twists and turns. While the economic backdrop seems to remain near perfect,  the
one thing we believe investors should be prepared for is more market volatility.
It also makes  sense to do  something  we've  always  advocated:  set  realistic
expectations, since, as we've also seen this year, markets can move down as fast
as they go up.

[A 1 1/4" x 1" photo of Edward J.  Boudreau  Jr.,  Chairman and Chief  Executive
Officer, flush right, next to second paragraph.]

   Use this time of  heightened  volatility  as an  opportunity  to review  your
portfolio's  asset allocations with your investment  professional.  After such a
strong advance in equities over the last two and a half years,  it could be time
to rebalance your portfolio,  if you haven't  already,  to maintain your desired
targets  of  diversification.  As part of that  process,  make  sure  that  your
investment  strategies  still reflect your individual time horizons,  objectives
and  risk  tolerance.   Despite  turbulence,   one  thing  remains  constant.  A
well-constructed  plan and a cool head can be the best tools for  reaching  your
financial goals. 

Sincerely,

/s/ Edward J. Boudreau, Jr.

EDWARD J. BOUDREAU, JR., CHAIRMAN AND CHIEF EXECUTIVE OFFICER

                     By James K. Ho, CFA, Portfolio Manager

                                  John Hancock

                Bonds experience a yar of changing expectations
                -----------------------------------------------

Recently,  the Fund's fiscal year end changed from December to May. What follows
is a discussion of the Fund's performance for the 12 months ended May 31, 1997.

During the 12 months ended May 31, 1997,  fixed-income  securities  had to dance
for their dinner amid a most fitful  investment  environment.  Leading  economic
indicators  continually  produced  mixed  signals  about the economy and lurking
inflation, causing investors to speculate on the Federal Reserve Board's actions
and the direction of interest  rates.  

   Last July,  when the bond market sold off amid concerns about the strength of
the economy and higher inflation,  the yield on the 30-year Treasury bond peaked
above the  psychologically  important 7% mark. As yields  generally  rose,  bond
prices declined. The bond market then rebounded in the fall as signs of economic
slowing eased investors'  inflation fears.  However,  no sooner did bonds regain
their  footing and rally when another  spate of data had  investors  questioning
their optimism by calendar year end. Further volatility accompanied the new year
as  investors  worried  about  the  Fed  raising  rates  at its  March  meeting.
Expectations  were realized when the Fed did indeed raise the federal funds rate
by .25% to 5.50%. The market has remained unsettled since.

Against this backdrop,  John Hancock  Sovereign Bond Fund  maintained an
even keel and closed fiscal 1997 on a positive  note. For the year ended May 31,
1997,  the Fund posted a total  return of 9.07% for Class A shares and 8.31% for
Class B shares at net asset value. The Fund  outperformed the average  corporate
debt  A-rated  fund,  as  tracked by Lipper  Analytical

Timely duration  adjustments  helped Fund 
While we generally try to avoid making major shifts in the  portfolio's  average
duration,  a measure of the Fund's  sensitivity to  interest-rate  changes,  the
adjustments  we did make  proved  timely.  At the  outset,  we kept  the  Fund's
duration shorter than other comparable bond funds and its benchmark,  the Lehman
Brothers Government/Corporate Bond Index. In addition, we "barbelled" the Fund's
holdings by aligning  assets at opposite  ends of the yield  curve,  owning both
short-term  and long-term  securities.  A defensive  orientation,  this strategy
helped provide a level of stability  when the yield curve  flattened last summer
and yields rose while prices declined.

left  column  is  "Investment";  the  header  for the right  column  is  "Recent
performance  ... and  what's  behind the  numbers."  The first  listing is Owens

the phrase "Paper prices  stabilize." The third listing is PageNet followed by a
down arrow and the phrase "Paging industry fundamentals deteriorating." Footnote
below reads: "See "Schedule of Investments."  Investment holdings are subject to
change."]

   Once the turbulence  settled in the fall, we extended  duration  slightly and
moved toward a more neutral  posture,  easing up on the barbell  structure.  The
Fund was then able to take full advantage of the market's price  appreciation in
October and November.  Coming into January,  we shortened duration yet again and
re-emphasized the barbell, allowing the Fund to weather the tumult caused by the
Fed's  action in March and  inaction  in May.  Given the  likelihood  of further
market  turbulence and Fed rate  increases,  we believe  maintaining a defensive
position is the most prudent course of action.

Tightening yield spreads 
Over the year,  yield spreads -- the  difference in yields  offered by corporate
and  Treasury  bonds,  and  corporate  bonds of varying  credit  quality -- have
narrowed,  contributing to the Fund's solid performance.  Healthy demand for new
corporate issues,  investors'  continuing  appetite for yield, and the financial
strength of corporate America helped boost corporate bond prices and push yields
lower, bringing them closer to one another and to the yields offered by Treasury
securities.

   Going  forward,  should the Fed raise rates yet again, a weaker equity market
and  economy  may be down the road.  Given  this  possibility,  we have begun to
upgrade the  portfolio's  credit  quality by slightly  reducing  our exposure to
high-yield  bonds and cyclical  issues,  those whose fortunes rise and fall with
the state of the economy.

   One way we have been able to improve  quality without  sacrificing  yield has
been to explore  opportunities in  emerging-market  corporate bonds whose values
are pegged to the U.S. dollar. As privatization and fiscal  responsibility  take
hold in many emerging  nations,  attractive  opportunities are coming to market,
such as Camuzzi Gas, a gas company in Argentina. Because no

corporation's  credit  rating  is  allowed  to be  higher  than that of its home
country's  government  bonds,  the  creditworthiness  of  many  emerging  market
corporate  debt  securities is often masked.  As a result,  the  emerging-market
bonds we have  selected for  inclusion  in the Fund offer high yields  with,  we
believe, comparatively low credit risk.

Pockets of strength 
In  creating a well  diversified  portfolio,  we often  uncover  new  investment
opportunities  that have not been well  researched  by market  analysts  and are
often misunderstood.  Such investments have the potential to generate high total
return.  Two more recent  structured  debt issues we purchased  include  capital
notes  and  home  equity  loan-backed  securities.   Capital  notes  are  junior
subordinated  debt securities of a bank or corporation.  Banks can carry them on
their  balance  sheets  as  equity  yet  deduct  their  interest.   Home  equity
loan-backed securities are asset-backed instruments that are rated AAA and offer
less prepayment risk than traditional  mortgage-backed  bonds. These issues came
to market fairly  cheaply  because  relatively  few analysts  followed  them. By
buying them early on, we capitalized on their price  appreciation as they gained
recognition and popularity in the marketplace.

- --------------------------------------------------------------------------------
"... we believe  maintaining a defensive  position is the most prudent course of
action."
- --------------------------------------------------------------------------------

   Holdings in the media and cable sectors,  which benefited from  industry-wide
consolidation,  also contributed to performance. Merger and acquisition activity
pervaded  the utility  industry as well.  The Fund owned  several  lower-quality
utility  bonds  that  instantly  traded  as  higher-quality   issues,   enjoying
substantial  price  appreciation,  once  higher-quality  companies took steps to
acquire  them.  Cleveland  Electric  and  Long  Island  Lighting  are two  worth
mentioning.

Outlook: caution is the watchword
Given the implications for economic growth, along with the fact that the Fed did
not  raise  interest  rates in May,  the  stage  appears  set for  further  rate
increases  this summer or fall.  We plan to stay  defensively  positioned in the
near term,  maintaining  a duration  shorter than that of the Fund's  benchmark.
With  corporate  bond spreads  still  historically  narrow,  the  yield-enhanced
sectors -- such as foreign  corporate bonds,  asset-backed  and  mortgage-backed
securities -- will continue to be our focus. Selectivity will be key in terms of
credit  quality and price.  Once the market  settles  down,  we will look for an
entry point to take on more interest rate exposure by increasing  our allocation
to Treasury bonds

                             A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total  returns  for the John  Hancock  Sovereign  Bond Fund.  Total  return is a
performance  measure  that  equals  the  sum  of all  income  and  capital  gain
distributions,  assuming  reinvestment of these  distributions and the change in
the price of the Fund's  shares,  expressed  as a  percentage  of the Fund's net
asset value per share.  Performance figures include the maximum applicable sales
charge of 4.5% for Class A shares. The effect of the maximum contingent deferred
sales  charge  for Class B shares  (maximum  5.0% and  declining  to 0% over six
years) is included in Class B performance.  For Class A shares,  different sales
charge  schedules  were in  effect  prior  to  September  28,  1989  and are not
reflected in the performance  information.  Remember that all figures  represent
past  performance  and are no  guarantee  of how the Fund  will  perform  in the
future.  Also,  keep in mind that the total return and share price of the Fund's
investments will fluctuate. As a result, your Fund's shares may be worth more or
less than their original cost, depending on when you sell them.

had  invested  on the day each  class of shares  started,  or that you have been
invested for the most recent 10 years. In either case, they assume that you have
reinvested  all  distributions.  For  comparison,  we've shown the same  $10,000
investment in the Lehman Brothers Corporate Bond Index - an unmanaged index that
mirrors the investment objectives and characteristics of the Fund.

[Line chart with the heading  Sovereign  Bond Fund:  Class A,  representing  the
growth  of a  hypothetical  $10,000  investment  over the most  recent 10 years.
Within the chart are three  lines.  The first line  represents  the value of the
Lehman Brothers Corporate Bond Index and is equal to $24,365 as of May 31, 1997.
The second line represents the value of the hypothetical $10,000 investment made
in the Sovereign Bond Fund, on May 31, 1987,  before sales charge,  and is equal
to  $23,420  as of May 31,  1997.  The third  line  represents  the value of the
Sovereign Bond Fund,  after sales charge,  and is equal to $22,366 as of May 31,
1997.]

[Line chart with the heading  Sovereign  Bond Fund:  Class B,  representing  the
growth of a hypothetical  $10,000  investment over the life of the fund.  Within
the chart are three  lines.  The first line  represents  the value of the Lehman
Brothers  Corporate  Bond Index and is equal to $12,248 as of May 31, 1997.  The
second line represents the value of the hypothetical  $10,000 investment made in
the Sovereign Bond Fund, on November 23, 1993, and is equal to $12,222 as of May
31, 1997. The third line represents the value of the Sovereign Bond Fund,  after
sales charge, and is equal to $11,922 as of May 31, 1997.]

                         NOTES TO FINANCIAL STATEMENTS

                    John Hancock Funds - Sovereign Bond Fund


NOTE A -
ACCOUNTING POLICIES
John  Hancock  Sovereign  Bond  Fund  (the  "Fund")  is a  diversified  open-end
investment  management  company,  registered under the Investment Company Act of
1940.  On May 21,  1996 the  Trustees  voted to  approve a change in the  fiscal
period end from  December 31 to May 31. This change is  effective  May 31, 1997.
The  investment  objective  of the Fund is to  generate  a high level of current
income,  consistent  with  prudent  investment  risk,  through  investment  in a
diversified  portfolio of freely  marketable debt securities.  

   The Trustees have  authorized  the issuance of multiple  classes of the Fund,
designated  as Class A and  Class B.  The  shares  of each  class  represent  an
interest in the same  portfolio of investments of the Fund and have equal rights
to voting, redemption,  dividends and liquidation, except that certain expenses,
subject to the  approval of the  Trustees,  may be applied  differently  to each
class of shares in accordance  with current  regulations  of the  Securities and
Exchange  Commission and the Internal Revenue  Service.  Shareholders of a class
which bears  distribution and service expenses under the terms of a distribution
plan, have exclusive voting rights regarding such distribution plan.

   Significant accounting policies of the Fund are as follows:

VALUATION OF  INVESTMENTS  Securities in the Fund's  portfolio are valued on the
basis of market quotations,  valuations provided by independent pricing services
or at fair value as  determined  in good  faith in  accordance  with  procedures
approved by the Trustees.  Short-term debt  investments  maturing within 60 days
are valued at amortized cost which approximates market value.

JOINT  REPURCHASE  AGREEMENT  Pursuant  to an  exemptive  order  issued  by  the
Securities  and  Exchange  Commission,  the Fund,  along with  other  registered
investment  companies having a management  contract with John Hancock  Advisers,
Inc. (the "Adviser"),a  wholly owned subsidiary of The Berkeley Financial Group,
may  participate in a joint  repurchase  agreement  transaction.  Aggregate cash
balances are invested in one or more  repurchase  agreements,  whose  underlying
securities are  obli-gations  of the U.S.  government  and/or its agencies.  The
Fund's  custodian bank receives  delivery of the  underlying  securities for the
joint account on the Fund's behalf. The Adviser is responsible for ensuring that
the agreement is fully collateralized at all times.

INVESTMENT  TRANSACTIONS  Investment transactions are recorded as of the date of
purchase,  sale  or  maturity.  Net  realized  gains  and  losses  on  sales  of
investments are determined on the identified cost basis.

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated  investment companies and
to  distribute  all of its taxable  income,  including  any net realized gain on
investment,  to its shareholders.  Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $29,796,705 of a capital
loss carryforward  available,  to the extent provided by regulations,  to offset
future net realized capital gains. To the extent that such  carryforward is used
by the Fund,  no  capital  gain  distributions  will be made.  The  carryforward
expires as follows: May 31, 1999 - $755,945, May 31, 2001 - $10,107,031, May 31,
2002 -  $9,347,493,  May 31, 2004 -  $8,402,805  and May 31, 2005 -  $1,183,431.
Expired capital loss  carryforwards  are  reclassified to capital paid-in in the
year of expiration.

DIVIDENDS,  DISTRIBUTIONS AND INTEREST Interest income on investment  securities
is  recorded  on the  accrual  basis.  The Fund  records  all  distributions  to
shareholders  from net investment  income and realized gains on the  ex-dividend
date.  Such   distributions   are  determined  in  conformity  with  income  tax
regulations,  which may differ from generally  accepted  accounting  principles.
Dividends  paid by the  Fund  with  respect  to each  class  of  shares  will be
calculated in the same manner,  at the same time and will be in the same amount,
except for the effect of expenses that may be applied differently to each class.

DISCOUNT ON SECURITIES  The Fund accretes  discount from par value on securities
from  either  the date of issue  or the  date of  purchase  over the life of the
security,  as required by the Internal Revenue Code. 

CLASS  ALLOCATIONS  Income,  common  expenses and realized and unrealized  gains
(losses) are  determined at the Fund level and allocated  daily to each class of
shares  based  on  the  appropriate  net  assets  of  the  respective   classes.
Distribution  and service fees, if any, are calculated  daily at the class level
based on the  appropriate  net  assets of each  class and the  specific  expense
rate(s) applicable to each class.

                    John Hancock Funds - Sovereign Bond Fund


USE OF ESTIMATES The  preparation  of these  financial  statements in accordance
with generally accepted  accounting  principles  incorporates  estimates made by
management in determining the reported amounts of assets, liabilities,  revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK  BORROWINGS The Fund is permitted to have bank  borrowings for temporary or
emergency purposes,  including the meeting of redemption requests that otherwise
might require the untimely disposition of securities.  The Fund had no borrowing
activity for the period ended May 31, 1997.

FINANCIAL  FUTURES  CONTRACTS  The  Fund  may buy  and  sell  financial  futures
contracts to hedge  against the effects of  fluctuations  in interest  rates and
other market conditions. Buying futures tends to increase the Fund's exposure to
the underlying instrument. Selling futures tends to decrease the Fund's exposure
to the underlying  instrument or hedge other Fund  instruments.  At the time the
Fund enters into a financial  futures  contract,  it will be required to deposit
with its  custodian a specified  amount of cash or U.S.  government  securities,
known as "initial  margin,"  equal to a certain  percentage  of the value of the
financial  future  contracts  being  traded.  Each day, the futures  contract is
valued  at the  official  settlement  price  of  the  board  of  trade  or  U.S.
commodities  exchange  on  which  it  trades.   Subsequent  payments,  known  as
"variation  margin,"  to and from the  broker  are made on a daily  basis as the
market price of the  financial  futures  contract  fluctuates.  Daily  variation
margin adjustments, arising from this "mark to market," are recorded by the Fund
as unrealized gains or losses.

   When the contracts are closed,  the Fund recognizes a gain or loss.  Risks of
entering into futures  contracts  include the  possibility  that there may be an
illiquid  market  and/or  that a change  in the  value of the  contract  may not
correlate with changes in the value of the underlying  securities.  In addition,
the Fund could be prevented  from  opening or realizing  the benefits of closing
out  futures  positions  because  of  position  limits or limits on daily  price
fluctuations imposed by an exchange.

   For federal  income tax  purposes,  the amount,  character  and timing of the
Fund's gains and/or losses can be affected as a result of futures transactions.

   At May 31,  1997,  open  positions  in financial  futures  contracts  were as
follows:

MANAGEMENT FEE AND TRANSACTIONS WITH
AFFILIATES AND OTHERS
Under the present investment management contract, the Fund pays a monthly fee to
the Adviser for a continuous investment program equivalent on an annual basis to
the sum of (a) 0.50% of the first $1,500,000,000 of the Fund's average daily net

   The Fund has a  distribution  agreement  with John Hancock  Funds,  Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser.  For the period ended May 31,
1997,  JH Funds  received net sales  charges of $695,419 with regard to sales of

shares.  For the period ended May 31, 1997,  contingent  deferred  sales charges
received by JH Funds amounted to $185,280.

   In  addition,  to  reimburse  JH  Funds  for  the  services  it  provides  as
distributor of shares of the Fund, the Fund has adopted  Distribution Plans with
respect  to Class A and Class B  pursuant  to Rule  12b-1  under the  Investment
Company Act of 1940.  Accordingly,  the Fund will make  payments to JH Funds for
distribution and service expenses at an annual rate not to exceed 0.30% of Class
A average  daily net assets and 1.00% of Class B average  daily net  assets,  to
reimburse JH Funds for its  distribution  and service costs.  Up to a maximum of
0.25% of these  payments may be service fees as defined by the amended  Rules of
Fair  Practice of the National  Association  of  Securities  Dealers.  Under the
amended  Rules of Fair  Practice  curtailment  of a portion of the Fund's  12b-1
payments could occur under certain circumstances.

   The Fund has a transfer agent agreement with John Hancock Signature Services,
Inc.  ("Signature  Services"),  an indirect subsidiary of JHMLICo. The Fund pays
transfer  agent fees based on the number of  shareholder  accounts  and  certain
out-of-pocket expenses.

   The Fund has an  agreement  with the  Adviser  to perform  necessary  tax and
financial  management services for the Fund. The compensation for the period was
at an annual rate of 0.01875% of the average net assets of the Fund.

   Mr. Edward J. Boudreau,  Jr., Ms. Anne C. Hodsdon and Mr. Richard S. Scipione
are trustees and/or officers of the Adviser,  and/or its affiliates,  as well as
Trustees of the Fund. The compensation of unaffiliated  Trustees is borne by the
Fund.  The  unaffiliated  Trustees  may  elect to defer for tax  purposes  their
receipt of this  compensation  under the John  Hancock  Group of Funds  Deferred
Compensation  Plan. The Fund makes investments into other John Hancock Funds, as
applicable, to cover its liability for the deferred compensation. Investments to
cover the Fund's  deferred  compensation  liability  are  recorded on the Fund's
books as an other asset.  The deferred  compensation  liability  and the related
other  asset are always  equal and are  marked to market on a periodic  basis to
reflect any income earned by the investment as well as any  unrealized  gains or
losses.   At  May  31,  1997,  the  Fund's  investment  to  cover  the  deferred
compensation had unrealized appreciation of $11,737.

REPORT OF INDEPENDENT AUDITORS
To the Board of Trustees and Shareholders of
John Hancock Sovereign Bond Fund

We have audited the accompanying statement of assets and liabilities of the John
Hancock Sovereign Bond Fund (the "Fund"), including the schedule of investments,
as of May 31, 1997, and the related  statement of operations for the period from
January 1, 1997 to May 31, 1997 and for the year ended  December 31,  1996,  the
statement of changes in net assets and the financial  highlights for each of the
periods indicated therein.  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 May
31, 1997, by correspondence  with the custodian and brokers,  and other auditing
procedures  when 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 the John Hancock Sovereign Bond Fund at May 31, 1997, the results of
its  operations for the period from January 1, 1997 to May 31, 1997 and the year
ended  December  31, 1996,  and the changes in its net assets and the  financial
highlights  for each of the  indicated  periods,  in conformity  with  generally
accepted  accounting  principles.
