Overseas Equity Fund (Formerly Global Balanced Fund)
Capital Guardian Trust Company                                   Management Team
- --------------------------------------------------------------------------------

..    In 2003, the Fund returned 39.85% underperforming its custom benchmark.

..    On May 1st, the Fund's name and strategy were changed, with no change in
     sub-adviser. The Fund now invests primarily in foreign large and mid sized
     equities, while previously, it invested globally in equity and fixed income
     securities.

..    Since May 1st, the Fund underperformed its benchmark primarily due to a
     modest cash exposure during the year. The Fund's performance did benefit
     from both favorable stock selection and country allocation decisions.

..    The Fund's exposures to selected sectors -- financials and information
     technology and countries -- Japan, UK and France -- contributed the most to
     absolute performance.

..    The top contributing stocks to absolute returns included Tokyo Electron and
     Sanofi-Synthelabo, while the key detractors included Yahoo Japan and
     Holcim.

..    The manager employs a multiple portfolio manager system, with each
     portfolio managed by several portfolio managers and research analysts. The
     manager selects securities using proprietary fundamental research
     Fundamental research seeks to uncover companies that are undervalued and
     asset rich.

*    Total returns are for the period ended December 31, 2003. Returns represent
     past performance, assume reinvestment of all distributions and are not
     indicative of future performance. Investment returns and principal value of
     fund shares will fluctuate so that shares, when redeemed, may be worth more
     or less than their original cost. There are special risks associated with
     international investing including currency fluctuations, political and
     economic instability, foreign taxation and different accounting standards,
     as outlined in the current prospectus. The performance of the fund on this
     page is reported net of Trust level charges (i.e. investment management
     fees and operating expenses). It does not reflect expense and charges of
     the applicable separate accounts and variable products, all of which vary
     to a considerable extent and are described in your product prospectus.
     Performance would be lower if expenses and charges of the separate accounts
     and products were reflected.

(a)  The amount shown at this caption for each share outstanding throughout the
     year may not accord with the change in the aggregate gains and losses in
     the portfolio securities for the year because of the timing of the
     purchases and withdrawals of the shares in relation to the fluctuating
     market values of the portfolio.

(b)  The performance does not reflect expenses and charges of the applicable
     separate accounts and variable products, all of which vary to a
     considerable extent and are described in your product's prospectus.

(c)  The Fund entered into a new sub-advisory agreement with Capital Guardian
     Trust Company during the period shown.

(d)  Expense ratio is net of expense reimbursements. Had such reimbursements not
     been made the expense ratio would have been 1.39%, 1.45%, 1.36%, 1.27%, and
     1.31%, for the years ended December 31, 2003, 2002, 2001, 2000, and 1999,
     respectively.

(e)  Had the Fund not amortized premiums and accreted discounts on debt
     securities, the annual ratio of net investment income to average net assets
     would have been 1.38% for the years ended December 31, 2001.

(f)  The Fund is required to calculate an expense ratio without taking into
     consideration any expense reductions related to expense offset
     arrangements.

NOTE A--ORGANIZATION

     John Hancock Overseas Equity Fund, (formerly John Hancock Global Balanced
Fund), (the "Fund") is a diversified series of John Hancock Variable Series
Trust I (the "Trust"), an open-end investment management company registered
under the Investment Company Act of 1940. The Trust is organized as a
Massachusetts business trust and consists of thirty different funds as of
December 31, 2003. The results of this Fund are included in this report. The
results of the other Funds in the Trust are presented under separate cover. The
Trust may add or delete Funds in the future to accommodate various investment
objectives. The Trust has issued shares of beneficial interest exclusively to
John Hancock Variable Life Account U ("JHVLAU"), John Hancock Variable Life
Account V ("JHVLAV"), John Hancock Variable Life Account S ("JHVLAS"), and John
Hancock Variable Annuity Account I ("JHVAAI") to fund policies and contracts
issued by the John Hancock Variable Life Insurance Company ("JHVLICO"), and to
John Hancock Variable Annuity Account U ("JHVAAU"), John Hancock Variable
Annuity Account V ("JHVAAV"), John Hancock Variable Life Account UV ("JHVLAUV"),
John Hancock Variable Annuity Account H ("JHVAAH"), and John Hancock Variable
Annuity Account JF ("JHVAAJF") to fund contracts and policies issued by John
Hancock Life Insurance Company ("John Hancock" or "JHLICO"), to John Hancock
Variable Life Account PPM-1 ("PPM-1"), and to John Hancock Variable Life Account
PPM-2 ("PPM-2").

NOTE B--ACCOUNTING POLICIES

     Valuation of investments: Investments in securities traded on national
securities exchanges in the United States or on equivalent foreign exchanges are
normally valued at the last quoted sales price on such exchanges as of the close
of business on the date of which assets are valued. Securities traded in the
over-the-counter market and securities traded with no sales on the day of
valuation are normally valued at their last available bid price. All Fund
securities initially expressed in terms of foreign currencies have been
translated into U.S. Dollars as described in "Currency Translation" below.

     Short-term investments, with a maturity not to exceed 60 days, are valued
at amortized cost, which approximates market value.

     Fair value pricing, determined in good faith by the Board of Trustees, may
be used by the Fund when current market values are unavailable or when an event
occurs after the close of the exchange on which the Fund's portfolio securities
are principally traded that is likely to have changed the value of the
securities. The use of fair value pricing by the Fund may cause the net asset
value of its shares to differ significantly from the net asset value that would
be calculated using current market values. Securities for which prices are not
available from an independent pricing service, but where an active market
exists, are valued using market quotations obtained from one or more dealers
that make markets in the securities.

     Investment security transactions are recorded on the date of purchase or
sale.

     Repurchase agreements: The Fund may enter into repurchase agreements which
are contracts under which the Fund would acquire a security for a relatively
short period (usually not more than 7 days) subject to the obligation of the
seller to repurchase and the Fund to resell such security at a fixed time and
price (representing the Fund's cost plus interest). The Fund will enter into
repurchase agreements only with member banks of the Federal Reserve System and
with "primary dealers" in United States Government Securities. The underlying
securities, which represent the collateral of the agreement, must be marked to
market daily to ensure that each repurchase agreement is fully collateralized at
all times. The Fund will not invest more than 10% of its net assets in
repurchase agreements maturing in more than 7 days.

     Joint trading account: Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the order permits the Fund to pool daily
uninvested cash balances into a joint account for the purpose of investing the
cash balances in short-term repurchase agreements, commercial paper and other
short-term investments which in no event will have a maturity in excess of 7
days. Joint account holdings as of December 31, 2003 are as follows:

                                                     ========

     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. Unrealized exchange
adjustments are included in unrealized appreciation (depreciation) of
investments. Transactions affecting statement of operations accounts and net
realized gain (loss) on investments are translated at the rates prevailing at
the dates of 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 gains or losses
from investments.

     Reported net realized gains and losses on foreign currency transactions
represent net gains and losses from sales and maturities of forward foreign
currency contracts, disposition of foreign currencies, currency gains and losses
realized between trade and settlement dates of security transactions, and the
difference between the amounts of net investment income accrued and the U.S.
dollar amount actually received. 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 rate.

     Expenses: Expenses directly attributable to the Fund are charged to the
Fund. Expenses not directly attributed to the Fund are allocated on the basis of
relative net assets of the Fund.

     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 syndicated line of credit agreements with State Street Bank and
Trust Company ("SSBT"), the Trust's record keeper and custodian and the Bank of
New York. These agreements enable the Fund to participate in an unsecured line
of credit, which permits borrowings up to $125 and $75 million, respectively.
Interest is charged to the Fund, based on its borrowing. In addition, a
commitment fee is charged to the Fund based on the average daily unused portion
of the line of credit and is allocated among the participating Funds in the
Trust. Interest expense paid under the line of credit is included under the
caption "Other fees" in the Statement of Operations.

     The Fund had borrowings under the line of credit during the year ended
December 31, 2003 as follows:

NOTE B--ACCOUNTING POLICIES--Continued

     Financial futures contracts: The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates and
other market conditions. At the time the Fund enters into a financial futures
contract, it will be required to deposit with its custodian a specified amount
of cash or U.S. government securities, known as "initial margin". Each day, the
futures contract is valued at the official settlement price of the Chicago Board
of Trade or U.S. commodities exchange. Daily adjustments, called variation
margin, arising from this "mark to market", are recorded by the Fund as
unrealized gains or losses.

     When the contracts are closed, the Fund recognizes a gain or a loss. Risks
of entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contract may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuations imposed by an exchange.At December 31, 2003, the Fund had no open
financial futures contracts.

     Forward foreign currency contracts: The Fund may use forward foreign
currency contracts to facilitate transactions in foreign securities and to
manage the Fund's currency exposure. Contracts to buy generally are used to
acquire exposure to foreign currencies, while contracts to sell are used to
hedge the Fund's investments against currency fluctuations. Neither type of
forward foreign currency transaction will eliminate fluctuations in the prices
of the Fund's securities or prevent loss if the price of such securities should
decline. The U.S. dollar value of a forward foreign currency contract is
determined using forward exchange rates supplied by a quotation service.
Realized gain (loss) on the purchases and sales of forward foreign currency
contracts is recognized on settlement date.

     As of December 31, 2003, the Fund had open forward foreign currency
contracts which contractually obligate the Fund to deliver or receive currencies
at a specified date, as follows:

                       Principal Amount                       Unrealized
                     Covered by Contract   Expiration Month   Gain (Loss)

     Federal income taxes: The Fund intends to comply with the requirements of
Subchapter M of the Internal Revenue Code applicable to regulated investment
companies and to distribute substantially all of its taxable income to
shareholders. Therefore, no federal income tax provision is required.

     As of December 31, 2003, the Fund had approximate net tax basis capital
loss carryforwards, which may be applied against any net taxable gains, as
follows: $478, $2,241 and $1,032 which expire in 2009, 2010 and 2011,
respectively.

     In addition, from the period November 1, 2003 through December 31, 2003,
the Fund incurred approximately $37 in net realized currency losses. As
permitted by tax regulations, the Fund intends to elect to defer these losses
and treat them as arising in the fiscal year ending on December 31, 2004.

NOTE B--ACCOUNTING POLICIES--Continued

     Dividends, Interest and Distributions: Dividend income is recorded on the
ex-dividend date and interest income is recorded on the accrual basis. Dividend
income for the Fund is shown net of foreign taxes withheld of $55. Realized
gains and losses from security transactions are determined on the basis of
identified cost.

     Dividends of net investment income will be declared and distributed monthly
by the Fund. The Fund will distribute all of its net realized capital gains
annually, at the end of its fiscal year.

     Estimates: The preparation of the financial statements in conformity with
accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

NOTE C--INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

     On February 5, 2003, the Board of Trustees of the Trust renewed its
Investment Advisory Agreement with John Hancock. For its services, John Hancock
receives monthly compensation at the following rate on an annual basis of the
Fund's net assets:

                         Between            Between
                     $150 Million and   $300 Million and   Excess Over
First $150 Million     $300 Million       $500 Million     $500 Million
- ------------------   ----------------   ----------------   ------------
      1.05%                0.95%             0.80%            0.75%

     In the event that normal operating expenses of the Fund, exclusive of
investment advisory fees, taxes, interest, brokerage commissions and
extraordinary expenses, shall exceed 0.10% of the Fund's daily net asset value,
John Hancock and JHVLICO will reimburse the Fund for such excess. Accordingly,
for the year ended December 31, 2003, the reimbursements paid from John Hancock
and JHVLICO were $87 to the Fund.

     The Fund entered into a commission recapture program, which enables it to
pay some of its operational expenses by recouping a portion of the commissions
it pays to a broker that is not a related party of the Fund. Expenses paid
through this program may include costs of custodial, transfer agency or
accounting services. The impact of this arrangement was a reduction of $1.

     John Hancock has entered into a Sub-Advisory Agreement with Capital
Guardian Trust Company, with respect to the Fund. Capital Guardian Trust Company
is an affiliate of John Hancock, and under its supervision, is responsible for
the day-to-day investment management of the Fund.

     Signator Investors, Inc., a wholly owned subsidiary of John Hancock is the
principal underwriter and transfer agent of the Trust. Certain officers and
trustees of the Trust are officers and directors of JHVLICO, JHVLAU, JHVLAV,
JHVLAS, JHVAAI, JHVLAUV, JHVAAV, JHVAAU, JHVAAH, JHVAAJF, PPM-1, and PPM-2, and
some are also officers of John Hancock. Fees for independent trustees are paid
by the Trust.

NOTE D--INVESTMENT TRANSACTIONS

     Purchases and proceeds from sales and maturities of investments, excluding
short-term securities and obligations of the U.S. government, for the Fund for
the year ended December 31, 2003 were as follows:

Purchases   Sales and Maturities
- ---------   --------------------
 $36,265          $30,303

     The identified cost of investments owned by the Fund (including earned
discount on corporate short-term notes, and commercial paper) and their
respective gross unrealized appreciation and depreciation for Federal income tax
purposes at December 31, 2003 were as follows:

Identified    Unrealized     Unrealized    Net Unrealized
   Cost      Appreciation   Depreciation    Appreciation
- ----------   ------------   ------------   --------------
  $40,215       $9,900         $(273)          $9,627

     Distribution of Income and Gains: Distributions of net investment income,
if any, are made at least annually. Net realized gains from investment
transactions, in excess of available capital loss carryforwards, would be
taxable to the Fund if not distributed, and, therefore, will be distributed to
shareholders at least annually. Earnings and profits distributed to shareholders
on redemption of fund shares may be utilized by the Fund, to the extent
permissible, as part of the Fund's dividends-paid deduction on its federal
income tax returns.

     The timing and characterization of certain income and capital gains
distributions are determined annually in accordance with federal tax
regulations, which may differ from accounting principles generally accepted in
the United States of America. These differences primarily relate to certain
securities sold at a loss, premium amortization and market discount accretion on
debt securities and investments in passive foreign investment companies and
foreign currency denominated investments. Additionally, as a result, net
investment income (loss) and net realized gain (loss) on investment transactions
for a reporting period may differ significantly from distributions during such
period. Accordingly, the Fund may periodically make reclassifications among
certain of its capital accounts without impacting the net asset value of the
Fund.

     At December 31, 2003, the Fund's components of distributable earnings on a
tax basis were as follows:

Undistributed   Undistributed
  Ordinary      Net Long-Term    Capital Loss   Net Unrealized
   Income       Capital Gain    Carryforwards    Appreciation
- -------------   -------------   -------------   --------------
     $--             $--            $3,751          $9,627

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

To the Contractowners, Policyholders, and
Board of Trustees of
John Hancock Variable Series Trust I

     We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of the Overseas Equity Fund (formerly,
Global Balanced Fund) (a portfolio included in the series of John Hancock
Variable Series Trust I {the "Trust"}) as of December 31, 2003, and the related
statement of operations for the year then ended, the statements of changes in
net assets for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended. These financial
statements and financial highlights are the responsibility of the Trust's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
and financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of December 31, 2003, by correspondence with the custodian and brokers,
or by other appropriate auditing procedures where replies from brokers were not
received. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Overseas Equity Fund of John Hancock Variable Series Trust I at December 31,
2003, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended, in conformity
with accounting principles generally accepted in the United States.

The John Hancock Variable Series Trust I consists of funds used as investment
options for various John Hancock variable life and variable annuity contracts.
Investors are not able to invest directly in the John Hancock Variable Series
Trust I.

If the total investment return for any fund for any given year appears unusually
high, the return may be attributable to unusually favorable market conditions
which will probably not be sustainable. For instance, a high total investment
return may reflect participation in IPOs, "hot" industries (e.g.,
internet-related companies), private placements, and/or leveraging investment
techniques during the period indicated. There is no assurance that any of those
methods, or any other investment technique will continue to have the same impact
on the fund's total investment returns.

All of the funds (except bond funds and equity index funds) may participate in
initial public offerings (IPOs). Under certain market conditions, such
participation could significantly improve a fund's total investment return.
There is no assurance that such market conditions will continue and provide the
same favorable impact on future investment returns.

Please refer to the prospectus for your product for additional information about
the investment options available. Variable life insurance and variable annuities
are sold by prospectus. These reports may be used as sales literature when
preceeded or accompanied by the funds' prospectus, which detail charges,
investment objectives, and operating policies.
