NOTES TO FINANCIAL STATEMENTS
Unaudited

NOTE A
Accounting policies
John Hancock European Equity Fund (the "Fund") is a diversified series of John
Hancock World Fund, an open-end management investment company registered under
the Investment Company Act of 1940. The investment objective of the Fund is to
achieve long-term capital growth.

The Trustees have authorized the issuance of multiple classes of shares of the
Fund, designated as Class A, Class B and Class C shares. The shares of each
class represent an interest in the same portfolio of investments of the Fund and
have equal rights as to voting, redemptions, 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 that bears distribution and service expenses under terms
of a distribution plan have exclusive voting rights to that 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, if quotations are not
readily available, or the value has been materially affected by events occurring
after the closing of a foreign market, 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. All portfolio transactions initially expressed in
terms of foreign currencies have been translated into U.S. dollars as described
in "Foreign currency translation" below.

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, LLC (the "Adviser"), a wholly owned
subsidiary of The Berkeley Financial Group, LLC, may participate in a joint
repurchase agreement transaction. Aggregate cash balances are invested in one or
more large repurchase agreements, whose underlying securities are obligations 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.

Foreign currency translation
All assets or liabilities initially expressed in terms of foreign currencies are
translated into U.S. dollars based on London currency exchange quotations as of
5:00 P.M., London time, on the date of any determination of the net asset value
of the Fund. Transactions affecting statement of operations accounts and net
realized gain (loss) on investments are translated at the rates prevailing at
the dates of the transactions.

The Fund does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
arising from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from sales of
foreign currency, currency gains or losses realized between the trade and
settlement dates on securities transactions and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains and losses arise from changes


                                       12


in the value of assets and liabilities, other than investments in securities,
resulting from changes in the exchange rates.

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. Capital gains realized on some foreign securities
are subject to foreign taxes, which are accrued as applicable.

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.

Expenses
The majority of the expenses are directly identifiable to an individual fund.
Expenses that are not readily identifiable to a specific fund will be allocated
in such a manner as deemed equitable, taking into consideration, among other
things, the nature and type of expense and the relative sizes of the funds.

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 has entered into a
syndicated line of credit agreement with various banks. This agreement enables
the Fund to participate with other funds managed by the Adviser in an unsecured
line of credit with banks, which permits borrowings of up to $250 million,
collectively. Interest is charged to each fund, based on its borrowing. In
addition, a commitment fee is charged to each fund based on the average daily
unused portion of the line of credit and is allocated among the participating
funds. The Fund had no borrowing activity under the line of credit during the
period ended April 30, 2003.

Options
The Fund may enter into option contracts. Listed options will be valued at the
last quoted sales price on the exchange on which they are primarily traded.
Over-the-counter options are valued at the mean between the last bid and asked
prices. Upon the writing of a call or put option, an amount equal to the premium
received by the Fund will be included in the Statement of Assets and Liabilities
as an asset and corresponding liability. The amount of the liability will be
subsequently marked to market to reflect the current market value of the written
option.

The Fund may use option contracts to manage its exposure to the price volatility
of financial instruments. Writing puts and buying calls will tend to increase
the Fund's exposure to the underlying instrument and buying puts and writing
calls will tend to decrease the Fund's exposure to the underlying instrument, or
hedge other Fund investments.

The maximum exposure to loss for any purchased options will be limited to the
premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

Risks may also arise if counterparties do not perform under the contracts' terms
("credit risk") or if the Fund is unable to offset a contract with a
counterparty on a timely basis ("liquidity risk"). Exchange-traded options have
minimal credit risk as the exchanges act as counterparties to each transaction,
and only present liquidity risk in highly unusual market conditions. To minimize
credit


                                       13


and liquidity risks in over-the-counter option contracts, the Fund will
continuously monitor the creditworthiness of all its counterparties.

At any particular time, except for purchased options, market or credit risk may
involve amounts in excess of those reflected in the Fund's Statement of Assets
and Liabilities.

The Fund had no written option transactions during the period ended April 30,
2003.

Forward foreign currency exchange contracts
The Fund may enter into forward foreign currency exchange contracts as a hedge
against the effect of fluctuations in currency exchange rates. A forward foreign
currency exchange contract involves an obligation to purchase or sell a specific
currency at a future date at a set price. The aggregate principal amounts of the
contracts are marked to market daily at the applicable foreign currency exchange
rates. Any resulting unrealized gains and losses are included in the
determination of the Fund's daily net assets. The Fund records realized gains
and losses at the time the forward foreign currency exchange contracts are
closed out. Risks may arise upon entering these contracts from the potential
inability of counterparties to meet the terms of the contract and from
unanticipated movements in the value of a foreign currency relative to the U.S.
dollar. These contracts involve market or credit risk in excess of the
unrealized gain or loss reflected in the Fund's Statement of Assets and
Liabilities.

The Fund may also purchase and sell forward contracts to facilitate the
settlement of foreign currency denominated portfolio transactions, under which
it intends to take delivery of the foreign currency. Such contracts normally
involve no market risk if they are offset by the currency amount of the
underlying transactions. The Fund had no open forward foreign currency exchange
contracts on April 30, 2003.

Federal income taxes
The Fund qualifies as a "regulated investment company" by complying with the
applicable provisions of the Internal Revenue Code and will not be subject to
federal income tax on taxable income that is distributed to shareholders.
Therefore, no federal income tax provision is required. For federal income tax
purposes, the Fund has $8,741,298 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 loss carryforward expires as follows:

October 31, 2006, -- $821,474, October 31, 2007 -- $1,234,369,  October 31, 2009
- --$3,678,367 and October 31, 2010 - $3,007,088.

Dividends, interest and distributions
Dividend income on investment securities is recorded on the ex-dividend date or,
in the case of some foreign securities, on the date thereafter when the Fund
identifies the dividend. Interest income on investment securities is recorded on
the accrual basis. Foreign income may be subject to foreign withholding taxes,
which are accrued as applicable.

The Fund records distributions to shareholders from net investment income and
net realized gains on the ex-dividend date. Distributions paid by the Fund with
respect to each class of shares are calculated in the same manner, at the same
time and are in the same amount, except for the effect of expenses that may be
applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. Distributions in excess of tax basis earnings and
profits, if any, are reported in the Fund's financial statements as a return of
capital.

Use of estimates
The preparation of these financial statements, in accordance with accounting
principles generally accepted in the United States of America, incorporates
estimates made by management in

determining the reported amount of assets, liabilities, revenues and expenses of
the Fund. Actual results could differ from these estimates.

NOTE B
Management fee and transactions
with affiliates and others
The Fund has an investment management contract with the Adviser. Under the
investment management contract, the Fund pays a monthly management fee to the
Adviser equivalent, on an annual basis, to the sum of: (a) 0.90% of the first
$500,000,000 of the Fund's average daily net asset value and (b) 0.70% of the
Fund's average daily net asset value in excess of $500,000,000. The Adviser has
a subadvisory agreement with Nicholas-Applegate Capital Management LP. The Fund
is not responsible for payment of the subadvisory fees.

The Adviser has agreed to limit the Fund's total expenses to 1.90%, 2.60% and
2.60% of the Fund's average daily net assets attributable to Class A, Class B
and Class C shares, respectively. Accordingly, the expense reduction amounted to
$76,982 for the period ended April 30, 2003. The Adviser reserves the right to
terminate this limitation in the future.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH Funds"), a
wholly owned subsidiary of the Adviser. The Fund has adopted Distribution Plans
with respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940 to reimburse JH Funds for the services it
provides as distributor of shares of the Fund. Accordingly, the Fund makes
monthly payments to JH Funds at an annual rate not to exceed 0.30% of Class A
average daily net assets and 1.00% of Class B and Class C average daily net
assets. A maximum of 0.25% of such payments may be service fees as defined by
the Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During the
period ended April 30, 2003, JH Funds received net up-front sales charges of
$3,447 with regard to sales of Class A shares. Of this amount, $387 was retained
and used for printing prospectuses, advertising, sales literature and other
purposes, $2,340 was paid as sales commissions to unrelated broker-dealers and
$720 was paid as sales commissions to sales personnel of Signator Investors,
Inc. ("Signator Investors"), a related broker-dealer. The Adviser's indirect
parent, John Hancock Life Insurance Company ("JHLICo"), is the indirect sole
shareholder of Signator Investors. During the period ended April 30, 2003, JH
Funds received net up-front sales charges of $62 with regard to sales of Class C
shares, all of which was paid as sales commissions to unrelated broker-dealers.

Class B shares that are redeemed within six years of purchase are subject to a
contingent deferred sales charge ("CDSC") at declining rates, beginning at 5.00%
of the lesser of the current market value at the time of redemption or the
original purchase cost of the shares being redeemed. Class C shares that are
redeemed within one year of purchase are subject to a CDSC at a rate of 1.00% of
the lesser of the current market value at the time of redemption or the original
purchase cost of the shares being redeemed. Proceeds from the CDSCs are paid to
JH Funds and are used in whole or in part to defray its expenses for providing
distribution related services to the Fund in connection with the sale of Class B
and Class C shares. During the period ended April 30, 2003, CDSCs received by JH
Funds amounted to $8,338 for Class B shares and none for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature Services,
Inc., an indirect subsidiary of JHLICo. The Fund pays a monthly transfer agent
fee at an annual rate of 0.05% of the Fund's average daily net asset value, plus
a fee based on the number of shareholder accounts and reimbursement for certain
out-of-pocket expenses.


                                       15


The Fund has an agreement with the Adviser to perform necessary tax, accounting
and legal services for the Fund. The compensation for the period was at an
annual rate of approximately 0.03% of the average net assets of the Fund.

The Adviser and other subsidiaries of JHLICo owned 150,000 shares of beneficial
interest of the Fund on April 30, 2003.

Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors 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. The Deferred Compensation
Plan investments had no impact on the operations of the Fund.

Investment transactions
Purchases and proceeds from sales or maturities of securities, other than

The cost of investments owned on April 30, 2003, including short-term
investments, for federal income tax purposes was $8,945,637. Gross unrealized
appreciation and depreciation of investments aggregated $1,112,730 and $136,713,
respectively, resulting in net unrealized appreciation of $976,017. The
difference between book basis and tax basis net unrealized appreciation of
investments is attributable primarily to the tax deferral of losses on wash
sales and the realization for tax purposes of unrealized gains on certain
forward foreign currency contracts.

Dear Fellow Shareholders,

After a strong start to 2003, the stock market succumbed to the pressures of a
weak economy, rising oil prices, concerns about corporate earnings and
uncertainties about the war in Iraq. The tide turned in April, when the war
ended and first-quarter corporate earnings came in better than expected. As a
result, the major indexes all gained some ground year to date through April 30,
2003, with the Dow Jones Industrial Average returning 2.50%, the Standard &
Poor's 500 Index returning 4.82% and the tech-heavy Nasdaq Composite Index up
9.64%. Bonds, which have outperformed stocks for the last three years, continued
their upward trend this year, as investors still sought their relative safety.

After the jarring stock market losses of the last three years, it's a relief for
investors to be reminded that the market is indeed cyclical, and does eventually
move up - not just down. But while the stock market has been clawing its way
back, the ride has been extremely volatile. Uncertainty still abounds about the
strength of the economy, geopolitical issues, corporate governance problems,
rising unemployment and the sustainability of corporate earnings growth. And
despite rallies late last year and in April, many investors are still so bruised
and skeptical that they have remained on the sidelines. Even though the
statistics suggest we might be emerging from this long, difficult bear market,
we're not quite ready to call it history.

While no one can predict when this bear market cycle will turn, investors can
take charge of how they maneuver through such uncertain times. First, take a
look at how your portfolio is allocated among stocks, bonds and cash to make
sure it's in the proper balance. Work with your investment professional, who
knows your long-term goals and can help keep you on the right track, rather than
being lured by today's stars, which could wind up tomorrow's laggards. And as
always, keep a long-term investment horizon. We believe this offers the best way
for you to survive the tough times and reach your investment objectives.

Sincerely,


/s/Maureen R. Ford,

MANAGER'S REPORT


The biotechnology stock sector
posted positive returns during the six months ended April 30, 2003, a welcome
relief after its disappointing losses in the previous year. During the period,
investors seemingly became more optimistic - albeit cautiously so - about the
group, buoyed by a number of favorable developments. More drugs were put into
clinical trials, which underscored the longer-term promise of this industry. In
addition, large pharmaceutical companies continued to pay a premium for
innovative new therapies, scooping up small biotech firms in the process. In
another positive development, a spate of FDA approvals seemingly signaled an
effective agenda on the part of the new commissioner of that agency. And a
number of biotechnology companies reported revenue and earnings gains that
exceeded investor expectations. Against that backdrop, large, well-established
biotech companies tended to outperform smaller, more speculative ventures.

"The biotechnology stock sector posted a positive return..."

PERFORMANCE AND STRATEGY REVIEW
For the six months ended April 30, 2003, John Hancock Biotechnology Fund's Class
A, Class B and Class C shares posted total returns of 0.54%, 0.18% and 0.18%,
respectively, at net asset value. During the same period, the more broadly
diversified average health/biotechnology fund had a total return of 4.99%,
according to Lipper, Inc.1, while the Standard & Poor's 500 Index returned
4.47%. Keep in mind that your net asset value return will be different from the
Fund's performance if you were not invested in the Fund for the entire period
and did not reinvest all distributions. See pages six and seven for historical
performance results.

While we were  gratified that the  biotechnology  sector showed renewed signs of
life during the past six months, our stock

selection  worked  against us during the period.  Additionally,  our  investment
focus on the narrow biotech sector may have curtailed our  performance  relative
to our peers. Other funds in the peer group had broader  investment  parameters,
giving them the ability to venture into  better-performing  health-care industry
groups.

LEADERS AND LAGGARDS
Our largest holding was also one of the best performers. Amgen, the world's
largest biotechnology company, enjoyed significantly higher sales and earnings.
It benefited from its 2002 acquisition of Immunex, which gave it the arthritis
drug Enbrel. Higher sales of anemia treatments Epogen and Aranesp, and drugs for
boosting the immune systems of chemotherapy patients also helped. According to
the company, another factor working in its favor was its ability to fill
prescriptions for thousands of patients on a waiting list, thanks to increased
manufacturing capacity. Another large holding that boosted performance was
Genzyme, helped by the expected FDA approval of two new drugs used to treat rare
genetic disorders, as well as its ability to correct problems with supplies of
existing drugs.

Another winner was MedImmune, helped in part by the excitement generated by the
company's expected introduction before the next flu season of a product called
FluMist. This nasal spray influenza vaccine is considered by many users to be a
more pleasant alternative to a flu shot. The company's existing products,
particularly Synagis, used to treat premature infants at risk for respiratory
distress, continued to gain wide acceptance by the medical community. Our
holdings in Scios also posted attractive gains, in part because it

                                                                               3



was purchased by  health-care  giant  Johnson & Johnson,  which was attracted to
Scios partly due to the company's experimental  rheumatoid arthritis drug. Scios
also enjoyed  success from its  congestive  heart failure drug,  which is in the
process of early acceptance by hospitals.

SPENDING SLOWDOWN HURTS SUPPLIERS
Suppliers to the biotech industry generally disappointed us during the period.
Many of these companies' earnings and revenues fell short of expectations due to
cautious spending in the academic, pharmaceutical and biotech industries.
Companies that were negatively affected by this trend included Affymetrix,

which makes chips used for genetic research;  Albany Molecular Research,  a drug
research and development company; and Charles River Laboratories, which provides
research tools and support that enable drug discovery and development.  Enzon, a
biopharmaceutical company that develops,  manufactures and markets therapies for
life-threatening  diseases,  was also a disappointment  mainly because investors
tended to view with some  skepticism the company's  proposed merger with another
biotech company.

OUTLOOK
In our opinion, it's quite likely that the biotech group will continue to face
some challenges in 2003, which may mean that the group will experience more
volatility. There are always ongoing hurdles for the group, such as the risks
involved in new product development; the rising costs of research, development,
manufacturing and sales; and the weaker financial condition of payers for health
care around the world. That said, we believe that there are things working in
the group's longer-term favor, specifically the fact that as we live longer
lives, we will require more and more health-care services and new biotech
products. As a growing number of people enter their mature years, new scientific
developments and improved efficiencies could serve as a catalyst for continued
growth of the biotechnology sector.


"...we  believe  that  there  are  things  working  in the  group's  longer-term
favor..."

Performance  figures  assume all  distributions  are  reinvested.  Returns  with
maximum sales charge  reflect a sales charge on Class A shares of 5% and Class C
shares of 1%, and the  applicable  contingent  deferred  sales charge  (CDSC) on
Class B and Class C shares.  The Class B shares' CDSC declines  annually between
years  1-6  according  to the  following  schedule:  5, 4, 3, 3, 2, 1%. No sales
charge will be assessed after the sixth year.  Class C shares held for less than
one  year are  subject  to a 1%  CDSC.  The  return  and  principal  value of an
investment in the Fund will  fluctuate,  so that shares,  when redeemed,  may be
worth more or less than the original cost.

The returns  reflect past  results and should not be  considered  indicative  of
future  performance.  The performance table above and the chart on the next page
do not  reflect  the  deduction  of taxes that a  shareholder  would pay on fund
distributions or the redemption of fund shares.

The Fund's  performance  results  reflect  any  applicable  expense  reductions,
without  which the  expenses  would  increase  and results  would have been less
favorable.  These reductions can be terminated in the future. See the prospectus
for details.

GROWTH OF
$10,000


This chart shows what happened to a hypothetical  $10,000  investment in Class A
shares for the period indicated. For comparison, we've shown the same investment
in the two indexes described on page 6.

- --------------------------------------------------------------------------------
Line chart with the heading "GROWTH OF $10,000." Within the chart are four
lines. The first line represents Index 1 and is equal to $7,638 as of April 30,
2003. The second line represents Index 2 and is equal to $5,966 as of April 30,
2003. The third line represents the value of the hypothetical $10,000 investment
made in the John Hancock Biotechnology Fund, before sales charge, and is equal
to $5,586 as of April 30, 2003. The fourth line represents the value of the same
hypothetical $10,000 investment made in the John Hancock Biotechnology Fund,
after sales charge, and is equal to $5,305 as of April 30, 2003.
- --------------------------------------------------------------------------------

Assuming all distributions  were reinvested for the period indicated,  the table
above shows the value of a $10,000  investment in the Fund's Class B and Class C
shares, respectively, as of April 30, 2003. Performance of the classes will vary
based on the difference in sales charges paid by  shareholders  investing in the
different classes and the fee structure of those classes.

1 No contingent deferred sales charge applicable.

NOTES TO
STATEMENTS

Unaudited

NOTE A
Accounting policies
John Hancock Biotechnology Fund (the "Fund") is a nondiversified series of John
Hancock World Fund, an open-end management investment company registered under
the Investment Company Act of 1940. The investment objective of the Fund is to
achieve long-term capital appreciation.

The Trustees have authorized the issuance of multiple classes of shares of the
Fund, designated as Class A, Class B and Class C shares. The shares of each
class represent an interest in the same portfolio of investments of the Fund and
have equal rights as to voting, redemptions, 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 that bears distribution and service expenses under terms
of a distribution plan have exclusive voting rights to that 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. Investments in AIM Cash Investment Trust
are valued at their net asset value each business day.

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, LLC (the "Adviser"), a wholly owned
subsidiary of The Berkeley Financial Group, LLC, may participate in a joint
repurchase agreement transaction. Aggregate cash balances are invested in one or
more large repurchase agreements, whose underlying securities are obligations of
the U.S. government and/or its agencies. The Fund's


16



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.

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.

Expenses

The majority of the expenses are directly  identifiable  to an individual  fund.
Expenses that are not readily  identifiable to a specific fund will be allocated
in such a manner as deemed  equitable,  taking into  consideration,  among other
things, the nature and type of expense and the relative sizes of the funds.

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 has entered into a
syndicated line of credit agreement with various banks. This agreement enables
the Fund to participate with other funds managed by the Adviser in an unsecured
line of credit with banks, which permits borrowings of up to $250 million,
collectively. Interest is charged to each fund, based on its borrowing. In
addition, a commitment fee is charged to each fund based on the average daily
unused portion of the line of credit and is allocated among the participating
funds. The Fund had no borrowing activity under the line of credit during the
period ended April 30, 2003.

Securities lending
The Fund may lend securities to certain qualified brokers who pay the Fund
negotiated lender fees. The loans are collateralized at all times with cash or
securities with a market value at least equal to the market value of the
securities on loan. As with other extensions of credit, the Fund may bear the
risk of delay of the loaned securities in recovery or even loss of rights in the
collateral, should the borrower of the securities fail financially. On April 30,
2003, the Fund loaned securities having a market value of $2,127,251
collateralized by cash in the amount of $2,169,796. The cash collateral was
invested in a short-term instrument.

Federal income taxes
The Fund  qualifies as a "regulated  investment  company" by complying  with the
applicable  provisions  of the Internal  Revenue Code and will not be subject to
federal  income tax on  taxable  income  that is  distributed  to  shareholders.
Therefore,  no federal income tax provision is required.  For federal income tax
purposes, the Fund has $5,313,084 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 loss carryforward  expires as follows:  October
31, 2009 - $139,642 and October 31, 2010 - $5,173,442.

Dividends, interest and distributions
Dividend income on investment securities is recorded on the ex-dividend date or,
in the case of some foreign securities, on the date thereafter when the Fund
identifies the dividend. Interest income on investment securities is recorded on
the accrual basis. Foreign income may be subject to foreign withholding taxes,
which are accrued as applicable.

The Fund records distributions to shareholders from


                                                                              17



net  investment   income  and  net  realized  gains  on  the  ex-dividend  date.
Distributions  paid by the  Fund  with  respect  to each  class  of  shares  are
calculated  in the same  manner,  at the same  time and are in the same  amount,
except for the effect of expenses that may be applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with income tax
regulations,  which may differ from accounting  principles generally accepted in
the United States of America.  Distributions in excess of tax basis earnings and
profits, if any, are reported in the Fund's financial  statements as a return of
capital.

Use of estimates
The preparation of these financial statements, in accordance with accounting
principles generally accepted in the United States of America, incorporates
estimates made by management in determining the reported amount of assets,
liabilities, revenues and expenses of the Fund. Actual results could differ from
these estimates.

NOTE B
Management fee and transactions with affiliates and others
The Fund has an investment management contract with the Adviser. Under the
investment management contract, the Fund pays a monthly management fee to the
Adviser equivalent, on an annual basis, to the sum of: (a) 0.90% of the first
$500,000,000 of the Fund's average daily net asset value, (b) 0.85% of the next
$500,000,000 and (c) 0.80% of the Fund's average daily net asset value in excess
of $1,000,000,000.

The Adviser has agreed to limit the Fund's expenses,  excluding the distribution
and service  fees,  to 1.30% of the Funds'  average  daily net assets,  at least
until February 28, 2004. Accordingly,  the expense reduction amounted to $68,586
for the period ended April 30, 2003. The Adviser reserves the right to terminate
this limitation in the future.

The Fund has  Distribution  Plans with John Hancock Funds,  LLC ("JH Funds"),  a
wholly owned subsidiary of the Adviser.  The Fund has adopted Distribution Plans
with  respect to Class A, Class B and Class C pursuant  to Rule 12b-1  under the
Investment  Company  Act of 1940 to  reimburse  JH  Funds  for the  services  it
provides  as  distributor  of shares of the Fund.  Accordingly,  the Fund  makes
monthly  payments to JH Funds at an annual  rate not to exceed  0.30% of Class A
average  daily net  assets  and  1.00% of Class B and Class C average  daily net
assets.  A maximum of 0.25% of such  payments  may be service fees as defined by
the Conduct Rules of the National  Association of Securities Dealers.  Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During the
period ended April 30, 2003, JH Funds received net up-front sales charges of
$6,938 with regard to sales of Class A shares. Of this amount, $1,037 was
retained and used for printing prospectuses, advertising, sales literature and
other purposes, $4,488 was paid as sales commissions to unrelated broker-dealers
and $1,413 was paid as sales commissions to sales personnel of Signator
Investors, Inc. ("Signator Investors"), a related broker-dealer. The Adviser's
indirect parent, John Hancock Life Insurance Company ("JHLICo"), is the indirect
sole shareholder of Signator Investors. During the period ended April 30, 2003,
JH Funds received net up-front sales charges of $531 with regard to sales of
Class C shares. Of this amount, $422 was paid as sales commissions to unrelated
broker-dealers and $109 was paid as sales commissions to sales personnel of
Signator Investors.

Class B shares that are redeemed within six years of purchase are subject to a
contingent deferred sales charge ("CDSC") at declining rates, beginning at 5.00%
of the lesser


18



of the current  market value at the time of redemption or the original  purchase
cost of the shares being  redeemed.  Class C shares that are redeemed within one
year of  purchase  are subject to a CDSC at a rate of 1.00% of the lesser of the
current market value at the time of redemption or the original  purchase cost of
the shares being redeemed.  Proceeds from the CDSCs are paid to JH Funds and are
used in whole or in part to  defray  its  expenses  for  providing  distribution
related  services to the Fund in connection with the sale of Class B and Class C
shares.  During the period  ended  April 30,  2003,  CDSCs  received by JH Funds
amounted to $8,186 for Class B shares and $119 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature Services,
Inc., an indirect subsidiary of JHLICo. The Fund pays a monthly transfer agent
fee at an annual rate of 0.05% of the average daily net asset value, plus a fee
based on the number of shareholder accounts and reimbursement for certain
out-of-pocket expenses.

The Fund has an agreement with the Adviser to perform necessary tax, accounting
and legal services for the Fund. The compensation for the period was at an
annual rate of approximately 0.03% of the average net assets of the Fund.

The Fund has an  independent  advisory  board composed of scientific and medical
experts  who  provide  the  investment  officers  of the Fund  with  advice  and
consultation on health-care  developments,  for which the Fund pays the advisory
board a fee.

The Adviser and other  subsidiaries of JHLICo owned 300,000 shares of beneficial
interest of the Fund on April 30, 2003.

Ms.  Maureen R. Ford and Mr. John M. DeCiccio are directors  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
investments as well as any unrealized gains or losses. The Deferred Compensation
Plan investments had no impact on the operations of the Fund.

Dear Fellow Shareholders,

After a strong start to 2003, the stock market succumbed to the
pressures of a weak economy, rising oil prices, concerns about corporate
earnings and uncertainties about the war in Iraq. The tide turned in
April, when the war ended and first-quarter corporate earnings came in
better than expected. As a result, the major indexes all gained some
ground year to date through April 30, 2003, with the Dow Jones
Industrial Average returning 2.50%, the Standard & Poor's 500 Index
returning 4.82% and the tech-heavy Nasdaq Composite Index up 9.64%.
Bonds, which have outperformed stocks for the last three years,
continued their upward trend this year, as investors still sought their
relative safety.

After the jarring stock market losses of the last three years, it's a
relief for investors to be reminded that the market is indeed cyclical,
and does eventually move up -- not just down. But while the stock market
has been clawing its way back, the ride has been extremely volatile.
Uncertainty still abounds about the strength of the economy,
geopolitical issues, corporate governance problems, rising unemployment
and the sustainability of corporate earnings growth. And despite rallies
late last year and in April, many investors are still so bruised and
skeptical that they have remained on the sidelines. Even though the
statistics suggest we might be emerging from this long, difficult bear
market, we're not quite ready to call it history.

While no one can predict when this bear market cycle will turn,
investors can take charge of how they maneuver through such uncertain
times. First, take a look at how your portfolio is allocated among
stocks, bonds and cash to make sure it's in the proper balance. Work
with your investment professional, who knows your long-term goals and
can help keep you on the right track, rather than being lured by today's
stars, which could wind up tomorrow's laggards. And as always, keep a
long-term investment horizon. We believe this offers the best way for
you to survive the tough times and reach your investment objectives.

Sincerely,

/S/ MAUREEN R. FORD

Maureen R. Ford,
Chairman and Chief Executive Officer

MANAGER'S
REPORT

BY LINDA I. MILLER, CFA, PORTFOLIO MANAGER

John Hancock
Health Sciences Fund

As a group, health-care stocks generally performed in line with the
overall stock market over the last six months, enjoying a bit of a
rebound. Part of health care's strength stemmed from investors' concerns
about the strength of an economic recovery. Health-care companies
generally aren't dependent on an upturn in the economy to do well. That
said, the various industry groups that comprise the health-care sector
posted mixed results. Makers of high-technology medical equipment --
such as those offering orthopedic implants, cardiovascular devices,
diagnostic and oncology treatment systems and others -- benefited from a
robust new-product cycle, industry consolidation, the relatively strong
financial position of their customers (primarily hospitals) and
increasing demand from the aging U.S. and European populations. In
addition, these companies generally were helped by favorable currency
trends. As the U.S. dollar declined in value relative to the euro, many
of these companies -- whose products became cheaper in euro terms and
thus more competitive -- enjoyed significant increases in European
sales. Managed care companies such as HMOs benefited from better
financial results based on some moderation in medical cost increases,
rising premiums for health insurance products and seasonal factors. Drug
stocks continued to face the challenges of patent expirations,
regulatory scrutiny of manufacturing procedures, inventory management
and the lack of new-product approvals. Biotech stock returns, generally
the most volatile in this group, varied from relatively strong gains for
the more visible, established companies and those who enjoyed positive
new-product or reimbursement developments, to weaker results for
companies with negative clinical developments or disappointing revenue
and earnings performance.

"...health-care stocks
 generally performed
 in line with the overall
 stock market..."

PERFORMANCE AND STRATEGY REVIEW

For the six months ended April 30, 2003, John Hancock Health Sciences
Fund's Class A, Class B and Class C shares posted total returns of
1.70%, 1.33% and 1.33%, respectively, at net asset value. The Fund's
returns lagged the 4.99% return of the average health-care/biotechnology
fund, according to Lipper, Inc.1 In this period, the broad Standard &
Poor's 500 Index returned 4.47%. Keep in mind that your net asset value
return will be different from the Fund's performance if you were not
invested in the Fund for the entire period and did not reinvest all
distributions. Please see pages six and seven for longer-term
performance information.

[A photo of Linda Miller flush right next to first paragraph.]

We believe a key reason for the Fund's lag was our overweighting --
relative to the overall health sector -- in companies that distribute
drugs. It stands to reason that if drug companies sell more drugs, which
they did during the period, then companies that distribute those drugs
would prosper. Unfortunately, many drug distributors came under pressure
because the drug companies streamlined operations, cutting into the
margins of the companies that service them. Against that backdrop,
Cardinal Health was one of our biggest disappointments during the
period.

"We also enjoyed good
 returns from our holdings
 in health-care equipment
 companies..."

BIOTECH, EQUIPMENT STOCKS BOOST RETURNS

One of the biggest positive contributors to the Fund's performance
during the period was Amgen, the world's largest biotechnology company.
Amgen enjoyed significantly higher sales, benefiting from its 2002
acquisition of Immunex, which gave it the arthritis drug Enbrel. Higher
sales of anemia treatments Epogen and Aranesp and drugs for boosting the
immune systems of chemotherapy patients also helped. According to the
company, another factor working in its favor was its ability to fill
prescriptions for thousands of patients on a waiting list, thanks to
increased manufacturing capacity. Another biotech company that helped
performance was Genzyme, profiting from the expected FDA approval of two
new drugs, as well as its ability to correct problems with supplies of
existing drugs.

[Table at top left-hand side of page entitled "Top five industry groups."
The first listing is Medical devices & products 22%, the second is
Drugs-biotechnology 21%, the third Drugs-major 15%, the fourth
Drugs-specialty & generic 11% and the fifth Drugs-diversified 8 %.]

We also enjoyed good returns from our holdings in health-care equipment
companies -- the manufacturers of heart devices, artificial knees, hips
and shoulders and other medical products -- including Medtronic, St.
Jude Medical, Integra LifeSciences and Stryker. While the weak economy,
war with Iraq and bad weather curtailed demand for nonessential medical
procedures, the demand for life-saving and essential medical procedures
continued to expand. Many of these companies also were helped by new
products and improving reimbursement trends. Thoratech, for example, was
boosted by Medicare's decision to pay for an artificial pump to keep the
blood flowing in heart-failure patients too sick for a heart transplant.

[Pie chart at middle of page with heading "Portfolio diversification As
a percentage of net assets on 4-30-03." The chart is divided into two
sections (from top to left): Common stocks 94% and Short-term
investments & other 6%.]

War, weather and the economy, however, did hold back some of our
health-care facilities companies, which saw a decline in patient
traffic. HCA, a leading hospital company, posted lower-than-expected
earnings due to those factors and others, including intensifying
pressure from managed care companies and heightened competition in some
markets.

[Table at top of page entitled "SCORECARD." The header for the left
column is "INVESTMENT" and the header for the right column is "PERIOD'S
PERFORMANCE...AND WHAT'S BEHIND THE NUMBERS." The first listing is Amgen
followed by an up arrow with the phrase "Strong demand for company's
products." The second listing is Thoratech followed by an up arrow with
the phrase "Medicare agrees to pay for heart pump." The third listing is
Cardinal Health followed by a down arrow with the phrase "Revenues
squeezed by drug makers."]

Large pharmaceutical company returns were inconsistent. Merck and Eli
Lilly turned in positive results, while Pfizer -- plagued by investors'
concerns over its mega-acquisition of Pharmacia -- lagged during the
period.

OUTLOOK

In our opinion, it's quite likely that the health-care group will
continue to face some challenges in 2003, which may mean that the group
experiences ongoing volatility. A rebound in economic growth, for
example, may prompt investors to move away from this sector into
faster-growing industry groups. And there are always ongoing hurdles for
the group, such as the risks involved in new-product development; the
rising costs of research, development, manufacturing and sales; and the
weaker financial condition of payers for health care around the world.
That said, we believe that there are also a number of positives working
in the group's longer-term favor including an aging world population,
continued innovation and discovery in the field of medical sciences and
reduced near-term political risk.

"...we believe that there are
 also a number of positives
 working in the group's
 longer-term favor..."

Performance figures assume all distributions are reinvested. Returns
with maximum sales charge reflect a sales charge on Class A shares of 5%
and Class C shares of 1%, and the applicable contingent deferred sales
charge (CDSC) on Class B and Class C shares. The Class B shares' CDSC
declines annually between years 1-6 according to the following
schedule: 5, 4, 3, 3, 2, 1%. No sales charge will be assessed after the
sixth year. Class C shares held for less than one year are subject to a
1% CDSC. The return and principal value of an investment in the Fund
will fluctuate, so that shares, when redeemed, may be worth more or less
than the original cost. Index figures do not reflect sales charges and
would be lower if they did.

Assuming all distributions were reinvested for the period indicated, the
table above shows the value of a $10,000 investment in the Fund's Class
B and Class C shares, respectively, as of April 30, 2003. Performance of
the classes will vary based on the difference in sales charges paid by
shareholders investing in the different classes and the fee structure of
those classes.

1 No contingent deferred sales charge applicable.

NOTE A
Accounting policies

John Hancock Health Sciences Fund (the "Fund") is a non-diversified
series of John Hancock World Fund, an open-end management investment
company registered under the Investment Company Act of 1940. The
investment objective of the Fund is to achieve long-term growth of
capital.

The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B and Class C shares. The
shares of each class represent an interest in the same portfolio of
investments of the Fund and have equal rights as to voting, redemptions,
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 that bears distribution and service expenses under terms of a
distribution plan have exclusive voting rights to that 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, if
quotations are not readily available, or the value has been materially
affected by events occurring after the closing of a foreign market, 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.
Investments in AIM Cash Investment Trust are valued at their net asset
value each business day. All portfolio transactions initially expressed
in terms of foreign currencies have been translated into U.S. dollars as
described in "Foreign currency translation" below.

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, LLC (the
"Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
LLC, may participate in a joint repurchase agreement transaction.
Aggregate cash balances are invested in one or more large repurchase
agreements, whose underlying securities are obligations 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.

Foreign currency translation

All assets or liabilities initially expressed in terms of foreign
currencies are translated into U.S. dollars based on London currency
exchange quotations as of 5:00 P.M., London time, on the date of any
determination of the net asset value of the Fund. Transactions affecting
statement of operations accounts and net realized gain (loss) on
investments are translated at the rates prevailing at the dates of the
transactions.

The Fund does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from the
fluctuations arising from changes in market prices of securities held.
Such fluctuations are included with the net realized and unrealized gain
or loss from investments.

Reported net realized foreign exchange gains or losses arise from sales
of foreign currency, currency gains or losses realized between the trade
and settlement dates on securities transactions and the difference
between the amounts of dividends, interest and foreign withholding taxes
recorded on the Fund's books and the U.S. dollar equivalent of the
amounts actually received or paid. Net unrealized foreign exchange gains
and losses arise from changes in the value of assets and liabilities,
other than invest -ments in securities, resulting from changes in the
exchange rates.

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. Capital gains realized on some
foreign securities are subject to foreign taxes, which are accrued as
applicable.

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. Distri
bution and service fees, ifany, 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.

Expenses

The majority of the expenses are directly identifiable to an individual
fund. Expenses that are not readily identifiable to a specific fund will
be allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and
the relative sizes of the funds.

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 has
entered into a syndicated line of credit agreement with various banks.
This agreement enables the Fund to participate with other funds managed
by the Adviser in an unsecured line of credit with banks, which permits
borrowings of up to $250 million, collectively. Interest is charged to
each fund, based on its borrowing. In addition, a commit -ment fee is
charged to each fund based on the average daily unused portion of the
line of credit and is allocated among the participating funds. The Fund
had no borrowing activity under the line of credit during the period
ended April 30, 2003.

Securities lending

The Fund may lend securities to certain qualified brokers who pay the
Fund negotiated lender fees. The loans are collateralized at all times
with cash or securities with a market value at least equal to the market
value of the securities on loan. As with other extensions of credit, the
Fund may bear the risk of delay of the loaned securities in recovery or
even loss of rights in the collateral, should the borrower of the
securities fail financially. On April 30, 2003, the Fund loaned
securities having a market value of $72,954,607 collateralized by cash
in the amount of $74,413,699. The cash collateral was invested in a
short-term instrument.

Federal income taxes

The Fund qualifies as a "regulated investment company" by complying with
the applicable provisions of the Internal Revenue Code and will not be
subject to federal income tax on taxable income that is distributed to
shareholders. Therefore, no federal income tax provision is required.
For federal income tax purposes, the Fund has $29,055,115 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 loss carryforward expires as follows: October 31, 2009 --
$16,212,040 and October 31, 2010 -- $12,843,075.

Dividends, interest and distributions

Dividend income on investment securities is recorded on the ex-dividend
date or, in the case of some foreign securities, on the date thereafter
when the Fund identifies the dividend. Interest income on investment
securities is recorded on the accrual basis. Foreign income may be
subject to foreign withholding taxes, which are accrued as applicable.

The Fund records distributions to shareholders from net investment
income and net realized gains on the ex-dividend date. Distributions
paid by the Fund with respect to each class of shares are calculated in
the same manner, at the same time and are in the same amount, except for
the effect of expenses that may be applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with
income tax regulations, which may differ from accounting principles
generally accepted in the United States of America. Distributions in
excess of tax basis earnings and profits, if any, are reported in the
Fund's financial statements as a return of capital.

Use of estimates

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

NOTE B
Management fee and transactions with affiliates and others

The Fund has an investment management contract with the Adviser. Under
the investment management contract, the Fund pays a quarterly management
fee to the Adviser equivalent, on an annual basis, to the sum of: (a)
0.80% of the first $200,000,000 of the Fund's average daily net asset
value and (b) 0.70% of the Fund's daily average net asset value in
excess of $200,000,000.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH
Funds"), a wholly owned subsidiary of the Adviser. The Fund has adopted
Distribution Plans with respect to Class A, Class B and Class C pursuant
to Rule 12b-1 under the Investment Company Act of 1940 to reimburse JH
Funds for the services it provides as distributor of shares of the Fund.
Accordingly, the Fund makes monthly payments to JH Funds at an annual
rate not to exceed 0.30% of Class A average daily net assets and 1.00%
of Class B and Class C average daily net assets. A maximum of 0.25% of
such payments may be service fees as defined by the Conduct Rules of the
National Association of Securities Dealers. Under the Conduct Rules,
curtailment of a portion of the Fund's 12b-1 payments could occur under
certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During
the period ended April 30, 2003, JH Funds received net up-front sales
charges of $92,746 with regard to sales of Class A shares. Of this
amount, $11,688 was retained and used for printing prospectuses,
advertising, sales literature and other purposes, $64,852 was paid as
sales commissions to unrelated broker-dealers and $16,206 was paid as
sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer. The Adviser's indirect
parent, John Hancock Life Insurance Company ("JHLICo"), is the indirect
sole shareholder of Signator Investors. During the period ended April
30, 2003, JH Funds received net up-front sales charges of $9,183 with
regard to sales of Class C shares. Of this amount, $8,905 was paid as
sales commissions to unrelated broker-dealers and $278 was paid as sales
commissions to sales personnel of Signator Investors.

Class B shares that are redeemed within six years of purchase are
subject to a contingent deferred sales charge ("CDSC") at declining
rates, beginning at 5.00% of the lesser of the current market value at
the time of redemption or the original purchase cost of the shares being
redeemed. Class C shares that are redeemed within one year of purchase
are subject to a CDSC at a rate of 1.00% of the lesser of the current
market value at the time of redemption or the original purchase cost of
the shares being redeemed. Proceeds from the CDSCs are paid to JH Funds
and are used in whole or in part to defray its expenses for providing
distribution-related services to the Fund in connection with the sale of
Class B and Class C shares. During the period ended April 30, 2003,
CDSCs received by JH Funds amounted to $182,298 for Class B shares and
$903 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc., an indirect subsidiary of JHLICo. The Fund pays a
monthly transfer agent fee at an annual rate of 0.05%, plus a fee based
on the number of shareholder accounts and reimbursement for certain
out-of-pocket expenses.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the
period was at an annual rate of approximately 0.04% of the average net
assets of the Fund.

The Fund has an independent advisory board composed of scientific and
medical experts who provide the investment officers of the Fund with
advice and consultation on health-care developments, for which the Fund
pays the advisory board a fee.

Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors 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 investments as well as any unrealized gains or losses. The
Deferred Compensation Plan investments had no impact on the operations
of the Fund.

NOTE D
Investment transactions

Purchases and proceeds from sales or maturities of securities, other
than short-term securities and obligations of the U.S. government,
during the period ended April 30, 2003, aggregated $97,931,460 and
$133,045,745, respectively.

The cost of investments owned on April 30, 2003, including short-term
investments, for federal income tax purposes was $285,767,749. Gross
unrealized appreciation and depreciation of investments aggregated
$60,621,022 and $4,671,633, respectively, resulting in net unrealized
appreciation of $55,949,389. The difference between book basis and tax
basis net unrealized appreciation of investments is attributable
primarily to the tax deferral of losses on wash sales.

Dear Fellow Shareholders,

After a strong start to 2003, the stock market succumbed to the
pressures of a weak economy, rising oil prices, concerns about corporate
earnings and uncertainties about the war in Iraq. The tide turned in
April, when the war ended and first-quarter corporate earnings came in
better than expected. As a result, the major indexes all gained some
ground year to date through April 30, 2003, with the Dow Jones
Industrial Average returning 2.50%, the Standard & Poor's 500 Index
returning 4.82% and the tech-heavy Nasdaq Composite Index up 9.64%.
Bonds, which have outperformed stocks for the last three years,
continued their upward trend this year, as investors still sought their
relative safety.

After the jarring stock market losses of the last three years, it's a
relief for investors to be reminded that the market is indeed cyclical,
and does eventually move up -- not just down. But while the stock market
has been clawing its way back, the ride has been extremely volatile.
Uncertainty still abounds about the strength of the economy,
geopolitical issues, corporate governance problems, rising unemployment
and the sustainability of corporate earnings growth. And despite rallies
late last year and in April, many investors are still so bruised and
skeptical that they have remained on the sidelines. Even though the
statistics suggest we might be emerging from this long, difficult bear
market, we're not quite ready to call it history.

While no one can predict when this bear market cycle will turn,
investors can take charge of how they maneuver through such uncertain
times. First, take a look at how your portfolio is allocated among
stocks, bonds and cash to make sure it's in the proper balance. Work
with your investment professional, who knows your long-term goals and
can help keep you on the right track, rather than being lured by today's
stars, which could wind up tomorrow's laggards. And as always, keep a
long-term investment horizon. We believe this offers the best way for
you to survive the tough times and reach your investment objectives.

Sincerely,

/S/ MAUREEN R. FORD

Maureen R. Ford,
Chairman and Chief Executive Officer

MANAGERS'
REPORT

The international stock markets endured yet another challenging period
during the six months ended April 30, 2003. Sluggish economic growth
worldwide, the specter of war in Iraq and deteriorating conditions in
the German and Japanese financial systems dampened investor sentiment.
Amid such uncertainty, Pacific Rim equities lost ground in the period,
with the representative MSCI All Country Pacific Free Index returning
- -4.98%.

In early October, shortly before the period began, international
equities, which became sharply oversold in the third quarter, rallied as
many beaten-down stocks rebounded. Late in 2002, international stocks
retreated somewhat as concerns arose that per-share earnings estimates
remained high.

"Amid such uncertainty,
 Pacific Rim equities lost
 ground in the period..."

The new year opened with investors holding high hopes, but declines in
each month of the first quarter dashed those hopes, as a combination of
war worries and weak economic data spurred a sell-off in stocks. In
developed markets, European equities outperformed Japanese equities, in
part due to a somewhat stronger euro and slightly weaker yen. Asian
performance was hurt most by negative returns in Korea, India and China.
In April, the international stock markets staged a strong rally as the
situation in Iraq appeared to be nearing resolution, energy prices
moderated and earnings -- although still weak -- came in slightly better
than anticipated. However, Pacific Rim equities advanced significantly
less than their counterparts in the United States and Europe.

FUND PERFORMANCE EXPLAINED

For the six months ended April 30, 2003, John Hancock Pacific Basin
Equities Fund's Class A, Class B and Class C shares posted total returns
of -11.81%, -12.16% and -12.16%, respectively, at net asset value.
During the same period, the average Pacific region fund returned
- -6.57%, according to Lipper, Inc.,1 while the benchmark MSCI All
Country Pacific Free Index fell 4.98%. Keep in mind that your net asset
value return will be different from the Fund's performance if you were
not invested in the Fund for the entire period and did not reinvest all
distributions. See pages six and seven for historical performance
information.

The Fund's underperformance relative to its peers and benchmark was
largely the result of disappointing stock selection in the
producers/manufacturing, financial services and consumer services
sectors. In particular, holdings in Japanese financial firms negatively
influenced both absolute and relative returns, as did investments in
leisure/gaming companies and electronic instruments manufacturers. By
country, Japanese and Australian stocks hurt the portfolio despite
underweight positions in both nations.

"...stock selection and over
 weight exposure to the
 consumer nondurables
 sector...proved to be the
 lone bright spot..."

On the positive side, stock selection and overweight exposure to the
consumer nondurables sector, while down slightly in absolute terms,
proved to be the lone bright spot for the portfolio. Industry holdings
that supported performance included agriculture, telephone companies and
advertising firms. By country, our overweight positions in Indonesia,
whose stock market rose 37%, and stock selection in Thailand and the
Philippines proved positive.

Top-performing holdings during the reporting period included Philippine
Long Distance Telephone Co., the leading supplier of domestic and
international telecommunications services in the Philippines, and Thai
Union Frozen Products, which specializes in frozen packaged seafood
products. Philippine Long Distance benefited from continuing
stronger-than-expected results at its Smart subsidiary, the removal of
provisions for its Piltel subsidiary, and lower compensation expenses as
it continues to substantially reduce headcount. Thai Union gained on
strong sales growth of its tuna products, particularly in the European
Union and the Middle East. The company is the only supplier of tuna
products to the U.S. military, so it also advanced on the prospect of
increased war-related spending. Decliners included numerous Japanese
companies, such as Nomura Securities, Mitsubishi Tokyo, Sony and
Hitachi.

groups." The first listing is Electronics 25%, the second is
Automobiles/trucks 9%, the third Retail 6%, the fourth Finance 5%, and
the fifth Leisure 4%.]

FUND MOVES

During the period, based on our assessment of individual stocks'
appreciation potential, we shifted assets out of Japan and Australia in
favor of opportunities in South Korea and China. We believe easing of
tensions with North Korea should help the South Korean stock market
regain its footing. Meanwhile, China -- despite the impact of Severe
Acute Respiratory Syndrome, or SARS -- continues to experience strong
export growth.

[Bar chart at middle of page with heading "Top Countries As a percentage
of net assets on 4-30-03." The chart is divided into five sections:
Japan 37%, South Korea 17%, Taiwan 8%, Hong Kong 6% and Singapore 6%. ]

OUTLOOK

On a macro level, geopolitical concerns are currently driving the equity
markets. Fundamentals remain weak, especially in Germany, France and
Japan. Capital equipment spending is beginning to stabilize, which bodes
well for future growth, and inflation remains tame. Although U.S.
companies generally have been meeting or beating earnings expectations,
international companies are not yet doing so. Positive developments
include a stability pact in the European Union that allows higher budget
deficits and government spending during exceptional periods, as well as
a reform package in Germany tightening unemployment and insurance
benefits. Japan was under selling pressure because its fiscal year ended
March 31, but we believe this pressure should be abating now that its
new fiscal year has begun.

[Table at top of page entitled "SCORECARD." The header for the left
column is "INVESTMENT" and the header for the right column is "PERIOD'S
PERFORMANCE...AND WHAT'S BEHIND THE NUMBERS." The first listing is
Philippine Long Distance Telephone followed by an up arrow with the
phrase "Stronger-than-expected performance; successful cost-control
measures. " The second listing is Sony Corp. followed by a down arrow
with the phrase "Weak sales and uncertainty regarding planned
restructuring." The third listing is Thai Union Frozen Products followed
by an up arrow with the phrase "Accelerating sales of tuna products."]

"Currently, Asia is
 posting attractive
 relative trade figures."

Currently, Asia is posting attractive relative trade figures. China, in
particular, is experiencing strong export growth. China is a source of
production for Taiwan, which has the technological know-how and the
customer base while China supplies the manufacturing capacity and labor.
Recently, Thailand has been the best-performing market in Asia.
Thailand's financial sector is undergoing recovery and the government
has placed a fiscal stimulus package in place.

Now that the overhang of Iraq is behind us, we believe the financial
markets should begin to normalize and investors should once again reward
fundamental strength.

Performance figures assume all distributions are reinvested. Returns
with maximum sales charge reflect a sales charge on Class A shares of 5%
and Class C shares of 1%, and the applicable contingent deferred sales
charge (CDSC) on Class B and Class C shares. The Class B shares' CDSC
declines annually between years 1-6 according to the following
schedule: 5, 4, 3, 3, 2, 1%. No sales charge will be assessed after the
sixth year. Class C shares held for less than one year are subject to a
1% CDSC. The return and principal value of an investment in the Fund
will fluctuate, so that shares, when redeemed, may be worth more or less
than the original cost. Index figures do not reflect sales charges and
would be lower if they did.

The returns reflect past results and should not be considered indicative
of future performance. The performance table above and the chart on the
next page do not reflect the deduction of taxes that a shareholder would
pay on fund distributions or the redemption of fund shares.



GROWTH OF

NOTE A
Accounting policies

John Hancock Pacific Basin Equities Fund (the "Fund") is a diversified
series of John Hancock World Fund, an open-end management investment
company registered under the Investment Company Act of 1940. The
investment objective of the Fund is to seek long-term capital
appreciation.

The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B and Class C shares. The
shares of each class represent an interest in the same portfolio of
investments of the Fund and have equal rights as to voting, redemptions,
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 that bears distribution and service expenses under terms of a
distribution plan have exclusive voting rights to that 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, if
quotations are not readily available or the value has been materially
affected by events occurring after the closing of a foreign market, 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. All
portfolio transactions initially expressed in terms of foreign
currencies have been translated into U.S. dollars as described in
"Foreign currency translation" below.

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, LLC (the
"Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
LLC, may participate in a joint repurchase agreement transaction.
Aggregate cash balances are invested in one or more large repurchase
agreements, whose underlying securities are obligations 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.

Foreign currency translation

All assets or liabilities initially expressed in terms of foreign
currencies are translated into U.S. dollars based on London currency
exchange quotations as of 5:00 P.M., London time, on the date of any
determination of the net asset value of the Fund. Transactions affecting
statement of operations accounts and net realized gain (loss) on
investments are translated at the rates prevailing at the dates of the
transactions.

The Fund does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from the
fluctuations arising from changes in market prices of securities held.
Such fluctuations are included with the net realized and unrealized gain
or loss from investments.

Reported net realized foreign exchange gains or losses arise from sales
of foreign currency, currency gains or losses realized between the trade
and settlement dates on securities transactions and the difference
between the amounts of dividends, interest and foreign withholding taxes
recorded on the Fund's books and the U.S. dollar equivalent of the
amounts actually received or paid. Net unrealized foreign exchange gains
and losses arise from changes in the value of assets and liabilities,
other than investments in securities, resulting from changes in the
exchange rates.

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. Capital gains realized on some
foreign securities are subject to foreign taxes, which are accrued as
applicable.

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.

Expenses

The majority of the expenses are directly identifiable to an individual
fund. Expenses that are not readily identifiable to a specific fund will
be allocated in such a manner as deemed equitable, taking into
consideration, among other things, the nature and type of expense and
the relative sizes of the funds.

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 has
entered into a syndicated line of credit agreement with various banks.
This agreement enables the Fund to participate with other funds managed
by the Adviser in an unsecured line of credit with banks, which permits
borrowings of up to $250 million, collectively. Interest is charged to
each fund, based on its borrowing. In addition, a commitment fee is
charged to each fund based on the average daily unused portion of the
line of credit and is allocated among the participating funds. The Fund
had no borrowing activity under the line of credit during the period
ended April 30, 2003.

Forward foreign currency exchange contracts

The Fund may enter into forward foreign currency exchange contracts as a
hedge against the effect of fluctuations in currency exchange rates. A
forward foreign currency exchange contract involves an obligation to
purchase or sell a specific currency at a future date at a set price.
The aggregate principal amounts of the contracts are marked to market
daily at the applicable foreign currency exchange rates. Any resulting
unrealized gains and losses are included in the determination of the
Fund's daily net assets. The Fund records realized gains and losses at
the time the forward foreign currency exchange contracts are closed out.
Risks may arise upon entering these contracts from the potential
inability of counterparties to meet the terms of the contracts and from
unanticipated movements in the value of a foreign currency relative to
the U.S. dollar. These contracts involve market or credit risk in excess
of the unrealized gain or loss reflected in the Fund's statement of
assets and liabilities.

The Fund may also purchase and sell forward contracts to facilitate the
settlement of foreign currency denominated portfolio transactions, under
which it intends to take delivery of the foreign currency. Such
contracts normally involve no market risk if they are offset by the
currency amount of the underlying transactions.

The Fund had no open forward foreign currency exchange contracts on
April 30, 2003.

Federal income taxes

The Fund qualifies as a "regulated investment company" by complying with
the applicable provisions of the Internal Revenue Code and will not be
subject to federal income tax on taxable income that is distributed to
shareholders. Therefore, no federal income tax provision is required.
For federal income tax purposes, the Fund has $13,280,111 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 entire amount of the loss carryforward expires October 31,
2009.

Dividends, interest and distributions

Dividend income on investment securities is recorded on the ex-dividend
date or, in the case of some foreign securities, on the date thereafter
when the Fund identifies the dividend. Interest income on investment
securities is recorded on the accrual basis. Foreign income may be
subject to foreign withholding taxes, capital gains and repatriation
taxes imposed by certain countries in which the Fund invests, which are
accrued as applicable.

The Fund records distributions to shareholders from net investment
income and net realized gains on the ex-dividend date. Distributions
paid by the Fund with respect to each class of shares are calculated in
the same manner, at the same time and are in the same amount, except for
the effect of expenses that may be applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with
income tax regulations, which may differ from accounting principles
generally accepted in the United States of America. Distributions in
excess of tax basis earnings and profits, if any, are reported in the
Fund's financial statements as a return of capital.

Use of estimates

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

NOTE B
Management fee and transactions with affiliates and others

The Fund has an investment management contract with the Adviser. Under
the investment management contract, the Fund pays a quarterly management
fee to the Adviser equivalent, on an annual basis, to the sum of: (a)
0.80% of the first $200,000,000 of the Fund's average daily net asset
value and (b) 0.70% of the Fund's average daily net asset value in
excess of $200,000,000. The Adviser has a subadvisory agreement with
Nicholas-Applegate Capital Management LP. The Fund is not responsible
for payment of the subadvisory fees.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH
Funds"), a wholly owned subsidiary of the Adviser. The Fund has adopted
Distribution Plans with respect to Class A, Class B and Class C pursuant
to Rule 12b-1 under the Investment Company Act of 1940 to reimburse JH
Funds for the services it provides as distributor of shares of the Fund.
Accordingly, the Fund makes monthly payments to JH Funds at an annual
rate not to exceed 0.30% of Class A average daily net assets and 1.00%
of Class B and Class C average daily net assets. A maximum of 0.25% of
such payments may be service fees as defined by the Conduct Rules of the
National Association of Securities Dealers. Under the Conduct Rules,
curtailment of a portion of the Fund's 12b-1 payments could occur under
certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During
the period ended April 30, 2003, JH Funds received net up-front sales
charges of $5,073 with regard to sales of Class A shares. Of this
amount, $619 was retained and used for printing prospectuses,
advertising, sales literature and other purposes, $3,075 was paid as
sales commissions to unrelated broker-dealers and $1,379 was paid as
sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer. The Adviser's indirect
parent, John Hancock Life Insurance Company ("JHLICo"), is the indirect
sole shareholder of Signator Investors. During the period ended April
30, 2003, JH Funds received net up-front sales charges of $1,632 with
regard to sales of Class C shares. Of this amount, $1,626 was paid as
sales commissions to unrelated broker-dealers and $6 was paid as sales
commissions to sales personnel of Signator Investors.

Class B shares that are redeemed within six years of purchase are
subject to a contingent deferred sales charge ("CDSC") at declining
rates, beginning at 5.00% of the lesser of the current market value at
the time of redemption or the original purchase cost of the shares being
redeemed. Class C shares that are redeemed within one year of purchase
are subject to a CDSC at a rate of 1.00% of the lesser of the current
market value at the time of redemption or the original purchase cost of
the shares being redeemed. Proceeds from the CDSCs are paid to JH Funds
and are used in whole or in part to defray its expenses for providing
distribution-related services to the Fund in connection with the sale of
Class B and Class C shares. During the period ended April 30, 2003,
CDSCs received by JH Funds amounted to $11,702 for Class B shares and
$523 for Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc., an indirect subsidiary of JHLICo. The Fund pays a
monthly transfer agent fee at an annual rate of 0.05% of the average
daily net asset value, plus a fee based on the number of shareholder
accounts and reimbursement for certain out-of-pocket expenses.

The Fund has an agreement with the Adviser to perform necessary tax,
accounting and legal services for the Fund. The compensation for the
period was at an annual rate of approximately 0.04%
of the average net assets of the Fund.

Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors 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 investments as well as any unrealized gains or losses. The
Deferred Compensation Plan investments had no impact on the operations
of the Fund.

NOTE D
Investment transactions

Purchases and proceeds from sales or maturities of securities, including
short-term securities and obligations of the U.S. government, during the
period ended April 30, 2003, aggregated $28,757,593 and $31,686,830,
respectively.

The cost of investments owned on April 30, 2003, including short-term
investments, for federal income tax purposes was $18,207,013. Gross
unrealized appreciation and depreciation of investments aggregated
$564,675 and $2,135,917, respectively, resulting in net unrealized
depreciation of $1,571,242. The difference between book basis and tax
basis net unrealized depreciation of investments is attributable
primarily to the tax deferral of losses on wash sales and the
realization for tax purposes of unrealized gains on certain forward
foreign currency contracts.

NOTES TO FINANCIAL STATEMENTS
Unaudited

NOTE A
Accounting policies
John Hancock International Small Cap Growth Fund (the "Fund") is a diversified
series of John Hancock World Fund, an open-end management investment company
registered under the Investment Company Act of 1940. The investment objective of
the Fund is to achieve long-term capital appreciation.

The Trustees have authorized the issuance of multiple classes of shares of the
Fund, designated as Class A, Class B and Class C shares. The shares of each
class represent an interest in the same portfolio of investments of the Fund and
have equal rights as to voting, redemptions, 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 that bears distribution and service expenses under terms
of a distribution plan have exclusive voting rights to that 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, if quotations are not
readily available, or the value has been materially affected by events occurring
after the closing of a foreign market, 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. All portfolio transactions initially expressed in
terms of foreign currencies have been translated into U.S. dollars as described
in "Foreign currency translation" below.

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, LLC (the "Adviser"), a wholly owned
subsidiary of The Berkeley Financial Group, LLC, may participate in a joint
repurchase agreement transaction. Aggregate cash balances are invested in one or
more large repurchase agreements, whose underlying securities are obligations 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.

Foreign currency translation
All assets or liabilities initially expressed in terms of foreign currencies are
translated into U.S. dollars based on London currency exchange quotations as of
5:00 P.M., London time, on the date of any determination of the net asset value
of the Fund. Transactions affecting statement of operations accounts and net
realized gain (loss) on investments are translated at the rates prevailing at
the dates of the transactions.

The Fund does not isolate that portion of the results of operations resulting
from changes in foreign exchange rates on investments from the fluctuations
arising from changes in market prices of securities held. Such fluctuations are
included with the net realized and unrealized gain or loss from investments.

Reported net realized foreign exchange gains or losses arise from sales of
foreign currency, currency gains or losses realized between the trade and
settlement dates on securities


13


transactions and the difference between the amounts of dividends, interest and
foreign withholding taxes recorded on the Fund's books and the U.S. dollar
equivalent of the amounts actually received or paid. Net unrealized foreign
exchange gains and losses arise from changes in the value of assets and
liabilities, other than investments in securities, resulting from changes in the
exchange rates.

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. Capital gains realized on some foreign securities
are subject to foreign taxes, which are accrued as applicable.

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.

Expenses
The majority of the expenses are directly identifiable to an individual fund.
Expenses that are not readily identifiable to a specific fund will be allocated
in such a manner as deemed equitable, taking into consideration, among other
things, the nature and type of expense and the relative sizes of the funds.

Forward foreign currency exchange contracts
The Fund may enter into forward foreign currency exchange contracts as a hedge
against the effect of fluctuations in currency exchange rates. A forward foreign
currency exchange contract involves an obligation to purchase or sell a specific
currency at a future date at a set price. The aggregate principal amounts of the
contracts are marked to market daily at the applicable foreign currency exchange
rates. Any resulting unrealized gains and losses are included in the
determination of the Fund's daily net assets. The Fund records realized gains
and losses at the time the forward foreign currency exchange contracts are
closed out. Risks may arise upon entering these contracts from the potential
inability of counterparties to meet the terms of the contract and from
unanticipated movements in the value of a foreign currency relative to the U.S.
dollar. These contracts involve market or credit risk in excess of the
unrealized gain or loss reflected in the Fund's Statement of Assets and
Liabilities.

The Fund may also purchase and sell forward contracts to facilitate the
settlement of foreign currency denominated portfolio transactions, under which
it intends to take delivery of the foreign currency. Such contracts normally
involve no market risk if they are offset by the currency amount of the
underlying transactions.

The Fund had no open forward foreign currency exchange contracts on April 30,
2003.

Federal income taxes
The Fund qualifies as a "regulated investment company" by complying with the
applicable provisions of the Internal Revenue Code and will not be subject to
federal income tax on taxable income that is distributed to shareholders.
Therefore, no federal income tax provision is required. For federal income tax
purposes, the Fund has $728,552 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 loss carryforward expires as follows: October
31, 2009 - $271,490 and October 31, 2010 - $457,062.

Dividend income on investment securities is recorded on the ex-dividend or, in
the case of some foreign securities, on the date thereafter when the Fund
identifies the dividend date. Interest income on investment securities is
recorded on the accrual basis. Foreign income may be subject to foreign
withholding taxes, which are accrued as applicable.

The Fund records distributions to shareholders from net investment income and
net realized gains on the ex-dividend date. Distributions paid by the Fund with
respect to each class of shares are calculated in the same manner, at the same
time and are in the same amount, except for the effect of expenses that may be
applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. Distributions in excess of tax basis earnings and
profits, if any, are reported in the Fund's financial statements as a return of
capital.

Use of estimates
The preparation of these financial statements, in accordance with accounting
principles generally accepted in the United States of America, incorporates
estimates made by management in determining the reported amount of assets,
liabilities, revenues and expenses of the Fund. Actual results could differ from
these estimates.

NOTE B
Management fee and transactions with affiliates and others
The Fund has an investment management contract with the Adviser. Under the
investment management contract, the Fund pays a monthly management fee to the
Adviser equivalent, on an annual basis, to the sum of: (a) 1.00% of the first
$500,000,000 of the Fund's average daily net asset value, (b) 0.90% of the next
$500,000,000 and (c) 0.85% of the Fund's average daily net asset value in excess
of $1,000,000,000. The Adviser has a subadvisory agreement with
Nicholas-Applegate Capital Management LP. The Fund is not responsible for
payment of the subadvisory fees.

The Adviser has agreed to limit the Fund's expenses, excluding the distribution
and service fees, to 1.30% of the Fund's average daily net assets, at least
until February 28, 2004. Accordingly, the expense reduction amounted to $41,782
for the period ended April 30, 2003. The Adviser reserves the right to terminate
this limitation in the future.

The Fund has Distribution Plans with John Hancock Funds, LLC ("JH Funds"), a
wholly owned subsidiary of the Adviser. The Fund has adopted Distribution Plans
with respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940 to reimburse JH Funds for the services it
provides as distributor of shares of the Fund. Accordingly, the Fund makes
monthly payments to JH Funds at an annual rate not to exceed 0.30% of Class A
average daily net assets and 1.00% of Class B and Class C average daily net
assets. A maximum of 0.25% of such payments may be service fees as defined by
the Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During the
period ended April 30, 2003, JH Funds received no up-front sales charges with
regard to Class A and Class C shares.

Class B shares that are redeemed within six years of purchase are subject to a
contingent deferred sales charge ("CDSC") at declining rates, beginning at 5.00%
of the lesser of the current market value at the time of redemption or the
original purchase cost of the shares being redeemed. Class C shares that are
redeemed within one year of purchase are subject to a CDSC at a rate of 1.00% of
the lesser of the current market value at the time of redemption or


15


the original purchase cost of the shares being redeemed. Proceeds from the CDSCs
are paid to JH Funds and are used in whole or in part to defray its expenses for
providing distribution related services to the Fund in connection with the sale
of Class B and Class C shares. During the period ended April 30, 2003, JH Funds
received no CDSCs with regard to Class B and Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature Services,
Inc., an indirect subsidiary of John Hancock Life Insurance Company ("JHlLCo").
The Fund pays a monthly transfer agent fee at an annual rate of 0.05% of the
average daily net asset value, plus a fee based on the number of shareholder
accounts and reimbursement for certain out-of-pocket expenses.

The Adviser and other subsidiaries of JHLICo owned 300,000 shares of beneficial
interest of the Fund on April 30, 2003.

The Fund has an agreement with the Adviser to perform necessary tax, accounting
and legal services for the Fund. The compensation for the period was at an
annual rate of approximately 0.03% of the average net assets of the Fund.

Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors 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
investments as well as any unrealized gains or losses. The Deferred Compensation
Plan investments had no impact on the operations of the Fund.

NOTE C
Fund share transactions
The Fund had no shares sold and repurchased during the last two periods. The
Fund has an unlimited number of shares authorized with no par value.

NOTE D
Investment transactions
Purchases and proceeds from sales or maturities of securities, other than
short-term securities and obligations of the U.S. government, during the period
ended April 30, 2003, aggregated $1,089,747 and $1,042,429, respectively

The cost of investments owned on April 30, 2003, including short-term
investments, for federal income tax purposes was $2,104,087. Gross unrealized
appreciation and depreciation of investments aggregated $235,671 and $88,945,
respectively, resulting in net unrealized appreciation of $146,726. The
difference between book basis and tax basis net unrealized appreciation of
investments is attributable primarily to the tax deferral of losses on wash
sales.

NOTE E
Subsequent events
On June 23, 2003, the Trustees approved the liquidation of the Fund.

NOTES TO FINANCIAL STATEMENTS
Unaudited

NOTE A
Accounting policies
John Hancock Consumer Industries Fund (the "Fund") is a non-diversified series
of John Hancock World Fund, an open-end management investment company registered
under the Investment Company Act of 1940. The investment objective of the Fund
is to achieve long term capital appreciation.

The Trustees have authorized the issuance of multiple classes of shares of the
Fund, designated as Class A, Class B and Class C shares. The shares of each
class represent an interest in the same portfolio of investments of the Fund and
have equal rights as to voting, redemptions, 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 that bears distribution and service expenses under terms
of a distribution plan have exclusive voting rights to that 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. Investments in AIM Cash Investment Trust
are valued at their net asset value each business day.

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, LLC (the "Adviser"), a wholly owned
subsidiary of The Berkeley Financial Group, LLC, may participate in a joint
repurchase agreement transaction. Aggregate cash balances are invested in one or
more large repurchase agreements, whose underlying securities are obligations 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.

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.

Expenses
The majority of the expenses are directly identifiable to an individual fund.
Expenses that are not readily identifiable to a specific fund will be allocated
in such a manner as deemed equitable, taking into consideration, among other
things, the nature and type of expense and the relative sizes of the funds.


                                       10


Securities lending
The Fund may lend securities to certain qualified brokers who pay the Fund
negotiated lender fees. These fees are included in interest income. The loans
are collateralized at all times with cash or securities with a market value at
least equal to the market value of the securities on loan. As with other
extensions of credit, the Fund may bear the risk of delay of the loaned
securities in recovery or even loss of rights in the collateral, should the
borrower of the securities fail financially. On April 30, 2003, the Fund loaned
securities having a market value of $67,197 collateralized by cash in the amount
of $68,422. The cash collateral was invested in a short-term instrument.

Federal income taxes
The Fund qualifies as a "regulated investment company" by complying with the
applicable provisions of the Internal Revenue Code and will not be subject to
federal income tax on taxable income that is distributed to shareholders.
Therefore, no federal income tax provision is required. For federal income tax
purposes, the Fund has $443,618 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 loss carryforward expires as follows: October
31, 2009 - $114,047 and October 31, 2010 - $329,571.

Dividends, interest and distributions
Dividend income on investment securities is recorded on the ex-dividend date or,
in the case of some foreign securities, on the date thereafter when the Fund
identifies the dividend. Interest income on investment securities is recorded on
the accrual basis. Foreign income may be subject to foreign withholding taxes,
which are accrued as applicable.

The Fund records distributions to shareholders from net investment income and
net realized gains on the ex-dividend date. Distributions paid by the Fund with
respect to each class of shares are calculated in the same manner, at the same
time and are in the same amount, except for the effect of expenses that may be
applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. Distributions in excess of tax basis earnings and
profits, if any, are reported in the Fund's financial statements as a return of
capital.

Use of estimates
The preparation of these financial statements, in accordance with accounting
principles generally accepted in the United States of America, incorporates
estimates made by management in determining the reported amount of assets,
liabilities, revenues and expenses of the Fund. Actual results could differ from
these estimates.

NOTE B
Management fee and transactions with affiliates and others
The Fund has an investment management contract with the Adviser. Under the
investment management contract, the Fund pays a monthly management fee to the
Adviser equivalent, on an annual basis, to the sum of: (a) 0.85% of the first
$500,000,000 of the Fund's average daily net asset value, (b) 0.80% of the next
$500,000,000 and (c) 0.75% in excess of $1,000,000,000.

The Adviser has agreed to limit the Fund's expenses, excluding the distribution
and service fees, to 1.25% of the Fund's average daily net assets, at least
until February 28, 2004. Accordingly, the expense reduction amounted to $12,356
for the period ended April 30, 2003. The Adviser reserves the right to terminate
this limitation in the future.


                                       11


The Fund has Distribution Plans with John Hancock Funds, LLC ("JH Funds"), a
wholly owned subsidiary of the Adviser. The Fund has adopted Distribution Plans
with respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940 to reimburse JH Funds for the services it
provides as distributor of shares of the Fund. Accordingly, the Fund makes
monthly payments to JH Funds at an annual rate not to exceed 0.30% of Class A
average daily net assets and 1.00% of Class B and Class C average daily net
assets. A maximum of 0.25% of such payments may be service fees as defined by
the Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During the
period ended April 30, 2003, JH Funds received no up-front sales charges with
regard to sales of Class A and Class C shares.

Class B shares that are redeemed within six years of purchase are subject to a
contingent deferred sales charge ("CDSC") at declining rates, beginning at 5.00%
of the lesser of the current market value at the time of redemption or the
original purchase cost of the shares being redeemed. Class C shares that are
redeemed within one year of purchase are subject to a CDSC at a rate of 1.00% of
the lesser of the current market value at the time of redemption or the original
purchase cost of the shares being redeemed. Proceeds from the CDSCs are paid to
JH Funds and are used in whole or in part to defray its expenses for providing
distribution related services to the Fund in connection with the sale of Class B
and Class C shares. During the period ended April 30, 2003, JH Funds received no
CDSCs with regard to Class B and Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature Services,
Inc., an indirect subsidiary of John Hancock Life Insurance Company ("JHLICo").
The Fund pays a monthly transfer agent fee at an annual rate of 0.05% of the
average daily net asset value, plus a fee based on the number of shareholder
accounts and reimbursement for certain out-of-pocket expenses.

The Fund has an agreement with the Adviser to perform necessary tax, accounting
and legal services for the Fund. The compensation for the period was at an
annual rate of approximately 0.03% of the average net assets of the Fund.

The Adviser and other subsidiaries of JHLICo owned 300,000 shares of beneficial
interest of the Fund on April 30, 2003.

Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors 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. The Deferred Compensation
Plan investments had no impact on the operations of the Fund.

NOTE C
Fund share transactions
The Fund has an unlimited number of shares authorized with no par value.


                                       12


NOTE D
Investment transactions
Purchases and proceeds from sales or maturities of securities, other than
short-term securities and obligations of the U.S. government, during the period
ended April 30, 2003, aggregated $1,518,005 and $1,459,115, respectively.

The cost of investments owned on April 30, 2003, including short-term
investments, for federal income tax purposes was $2,513,672. Gross unrealized
appreciation and depreciation of investments aggregated $336,241 and $77,407,
respectively, resulting in net unrealized appreciation of $258,834. The
difference between book basis and tax basis net unrealized appreciation of
investments is attributable primarily to the tax deferral of losses on wash
sales.

NOTE E
Subsequent events
On May 20, 2003, the Trustees approved the liquidation of the Fund after the
close of business on May 7, 2003.

NOTES TO FINANCIAL STATEMENTS
Unaudited

NOTE A
Accounting policies
John Hancock Communications Fund (the "Fund") is a non-diversified series of
John Hancock World Fund, an open-end management investment company registered
under the Investment Company Act of 1940. The investment objective of the Fund
is to seek long-term capital appreciation.

The Trustees have authorized the issuance of multiple classes of shares of the
Fund, designated as Class A, Class B and Class C shares. The shares of each
class represent an interest in the same portfolio of investments of the Fund and
have equal rights as to voting, redemptions, 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 that bears distribution and service expenses under terms
of a distribution plan have exclusive voting rights to that distribution plan.

Significant accounting policies of the Fund were 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. Investments in AIM Cash Investment Trust
are valued at their net asset value each business day.

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, LLC (the "Adviser"), a wholly owned
subsidiary of The Berkeley Financial Group, LLC, may participate in a joint
repurchase agreement transaction. Aggregate cash balances are invested in one or
more large repurchase agreements, whose underlying securities are obligations 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.

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.

Expenses
The majority of the expenses are directly identifiable to an individual fund.
Expenses that are not readily identifiable to a specific fund will be allocated
in such a manner as deemed equitable, taking into consideration, among other
things, the nature and type of expense and the relative sizes of the funds.


                                       9


Securities lending
The Fund may lend securities to certain qualified brokers who pay the Fund
negotiated lender fees. The loans are collateralized at all times with cash or
securities with a market value at least equal to the market value of the
securities on loan. As with other extensions of credit, the Fund may bear the
risk of delay of the loaned securities in recovery or even loss of rights in the
collateral, should the borrower of the securities fail financially. On April 30,
2003, the Fund loaned securities having a market value of $33,748 collateralized
by cash in the amount of $34,303. The cash collateral was invested in a
short-term instrument.

Federal income taxes
The Fund qualifies as a "regulated investment company" by complying with the
applicable provisions of the Internal Revenue Code and will not be subject to
federal income tax on taxable income that is distributed to shareholders.
Therefore, no federal income tax provision is required. For federal income tax
purposes, the Fund has $1,426,509 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 loss carryforward expires as follows: October
31, 2009 - $558,949 and October 31, 2010 - $867,560.

Dividends, interest and distributions
Dividend income on investment securities is recorded on the ex-dividend date or,
in the case of some foreign securities, on the date thereafter when the Fund
identifies the dividend. Interest income on investment securities is recorded on
the accrual basis. Foreign income may be subject to foreign withholding taxes,
which are accrued as applicable.

The Fund records distributions to shareholders from net investment income and
net realized gains on the ex-dividend date. Distributions paid by the Fund with
respect to each class of shares are calculated in the same manner, at the same
time and are in the same amount, except for the effect of expenses that may be
applied differently to each class.

Such distributions, on a tax basis, are determined in conformity with income tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. Distributions in excess of tax basis earnings and
profits, if any, are reported in the Fund's financial statements as a return of
capital.

Use of estimates
The preparation of these financial statements, in accordance with accounting
principles generally accepted in the United States of America, incorporates
estimates made by management in determining the reported amount of assets,
liabilities, revenues and expenses of the Fund. Actual results could differ from
these estimates.

NOTE B
Management fee and transactions
with affiliates and others
The Fund has an investment management contract with the Adviser. Under the
investment management contract, the Fund pays a monthly management fee to the
Adviser equivalent, on an annual basis, to the sum of: (a) 0.90% of the first
$500,000,000 of the Fund's average daily net asset value (b) 0.85% of the next
$500,000,000 and (c) 0.80% of the Fund's average daily net asset value in excess
of $1,000,000,000.

The Adviser has agreed to limit the Fund's expenses, excluding distribution and
service fees, to 1.30% of the Fund's average daily net assets, at least until
February 28, 2004. Accordingly, the expense reduction amounted to $15,154 for
the period ended April 30, 2003. The Adviser reserves the right to terminate
this limitation in the future.


                                       10


The Fund has Distribution Plans with John Hancock Funds, LLC ("JH Funds"), a
wholly owned subsidiary of the Adviser. The Fund has adopted Distribution Plans
with respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940 to reimburse JH Funds for the services it
provides as distributor of shares of the Fund. Accordingly, the Fund makes
monthly payments to JH Funds at an annual rate not to exceed 0.30% of Class A
average daily net assets and 1.00% of Class B and Class C average daily net
assets. A maximum of 0.25% of such payments may be service fees as defined by
the Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, curtailment of a portion of the Fund's 12b-1 payments could occur
under certain circumstances.

Class A and Class C shares are assessed up-front sales charges. During the
period ended April 30, 2003, JH Funds received no up-front sales charges with
regard to sales of Class A and Class C shares.

Class B shares that are redeemed within six years of purchase are subject to a
contingent deferred sales charge ("CDSC") at declining rates, beginning at 5.00%
of the lesser of the current market value at the time of redemption or the
original purchase cost of the shares being redeemed. Class C shares that are
redeemed within one year of purchase are subject to a CDSC at a rate of 1.00% of
the lesser of the current market value at the time of redemption or the original
purchase cost of the shares being redeemed. Proceeds from the CDSCs are paid to
JH Funds and are used in whole or in part to defray its expenses for providing
distribution related services to the Fund in connection with the sale of Class B
and Class C shares. During the period ended April 30, 2003, JH Funds received no
CDSCs with regard to Class B and Class C shares.

The Fund has a transfer agent agreement with John Hancock Signature Services,
Inc., an indirect subsidiary of John Hancock Life Insurance Company ("JHLICo").
The Fund pays a monthly transfer agent fee at an annual rate of 0.05% of the
average daily net asset value, plus a fee based on the number of shareholder
accounts and reimbursement for certain out-of-pocket expenses.

The Fund has an agreement with the Adviser to perform necessary tax, accounting
and legal services for the Fund. The compensation for the period was at an
annual rate of approximately 0.03% of the average net assets of the Fund.

The Adviser and other subsidiaries of JHLICo owned 300,000 shares of beneficial
interest of the Fund on April 30, 2003.

Ms. Maureen R. Ford and Mr. John M. DeCiccio are directors 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. The Deferred Compensation
Plan investments had no impact on the operations of the Fund.
