                              GENERAL INFORMATION
   
  John Hancock Variable Series Trust I is an open-end management investment
company reorganized as a business trust under the laws of Massachusetts
effective April 29, 1988. The Fund has twenty-four Portfolios, each with a
separate series of shares. The twenty-four Portfolios are listed on the cover
pages of this Prospectus and in the tables below. With the exception of the
Special Opportunities, Mid Cap Growth, and International Balanced Portfolios,
each of the Portfolios is a "diversified" Portfolio within the meaning of the
Investment Company Act of 1940. The Fund's Board of Trustees is authorized to
create additional Portfolios or delete Portfolios.     
 
  Shares of the Fund currently are sold to John Hancock Variable Life Accounts
U, V, and S to fund variable life insurance policies issued by John Hancock
Variable Life Insurance Company ("JHVLICO"); to John Hancock Variable Annuity
Accounts U and V to fund variable annuity contracts issued by John Hancock
Mutual Life Insurance Company ("John Hancock"); to John Hancock Variable
Annuity Account I to fund variable annuity contracts issued by JHVLICO; and to
John Hancock Mutual Variable Life Insurance Account UV to fund variable life
insurance policies issued by John Hancock. In the future, shares may be sold
to other separate investment accounts of JHVLICO and John Hancock. Each of
these accounts of JHVLICO and John Hancock is hereinafter referred to as a
"Separate Account". JHVLICO and John Hancock currently do not foresee any
disadvantages to contractholders arising out of the fact that the Fund offers
its shares to JHVLICO's variable life insurance policies and variable annuity
contracts and John Hancock's variable life insurance policies and variable
annuity contracts. However, should a material irreconcilable conflict arise
between the Separate Accounts, the conflict could result in one of the
Separate Accounts terminating its relationship with the Fund thus
necessitating the liquidation of Portfolio securities and thereby having an
adverse impact on the net asset value of the Fund. The Fund's Board of
Trustees monitors events to identify any possible material conflicts and to
determine what action should be taken to prevent any negative effect on the
Fund.
          
  Because Fund shares will be held in Separate Accounts of JHVLICO or John
Hancock, any reference in this Prospectus or in the Statement of Additional
Information to shareholders of the Fund refers to those insurance companies,
and not to the ultimate purchasers of policies or contracts whose benefits are
funded by the Portfolios (collectively, "contractholders") who may have an
indirect interest in the Fund. The rights of such contractholders are
described in the appropriate Separate Account Prospectus attached at the front
of this Prospectus.

(1) At the date of this prospectus, John Hancock is voluntarily waiving the
    management fees for this Portfolio, although it expects to discontinue the
    waiver in the near future. Absent such voluntary waiver by John Hancock,
    the management fees will be 0.20%, which reflects a 0.05% reduction
    effective May 1, 1997.
(2) Restated to reflect the estimated effect of expense reallocation expected
    to become effective July 1, 1997.
   
(3) John Hancock reimburses a Portfolio when the Portfolio's Other Expenses,
    excluding taxes, brokerage and the like, exceed 0.25% of its average daily
    net asset value. This was done for the year ended December 31, 1997 with
    respect to    of the Fund's Portfolios. Absent the reimbursement, the
    Other Expenses as a percentage of average daily net assets would have been
    as follows: Equity Index, 1.61%; Large Cap Value, 1.89%; Mid Cap Value,
    2.15%; Mid Cap Growth, 2.34%; Small Cap Value, 2.06%; Small Cap Growth,
    1.55%; International Balanced, 1.44%; International Opportunities, 2.76%;
    Short-Term U.S. Government, 0.79%; Strategic Bond, 1.57%. Also, John
    Hancock voluntarily reimbursed the Equity Index Portfolio for its first
    0.25% of Other Expenses for 1996. This additional reimbursement is not
    shown in the table because it is voluntary and is expected to be
    discontinued at some point in the foreseeable future.     
(4) Restated to reflect a 0.20% reduction in advisory fee effective May 1,
    1997.
   
(5) "Other Expenses" are based upon estimates for the current fiscal year. It
    is expected that, in the absence of the expense reimbursement arrangements
    referred to above, the actual expenses of this Portfolio may be greater.

  The following tables give information regarding income, expenses, and
capital changes in the Portfolios for a share outstanding throughout the
periods indicated, and other supplementary data. The tables have been audited
by Ernst & Young LLP, independent auditors of the Fund, whose report thereon,
and on the financial statements of the Fund for the year ended December 31,
1996, is incorporated by reference into the Statement of Additional
Information. These tables should be read in conjunction with the Fund's
financial statements and notes thereto. A copy of the Annual Report to

the Annual Report. No Management's Discussion and Analysis, financial
statements or financial highlights are provided for the Small/Mid Cap CORE
Equity, Global Equity, International Equity Index, Emerging Markets Equity,
Diversified Bond Index, or High Yield Bond Portfolios because they did not
have any assets, and had not commenced operations at December 31, 1997.

                      INVESTMENT OBJECTIVES AND POLICIES
 
  Each Portfolio of the Fund has a different investment objective, which it
pursues through the separate investment policies described below. Additional
investment practices of some or all of the Portfolios are discussed below
under "Investment Practices." The differences in objectives, policies, and
practices among the various Portfolios can be expected to affect each
Portfolio's investment return as well as the degree of market and financial
risks to which each Portfolio is subject. Please refer to "Risk Factors" below
for a discussion of certain risks applicable to each Portfolio.
 
  Managed Portfolio: The investment objective of the Managed Portfolio is to
achieve maximum long-term total return consistent with prudent investment
risk. Total return consists of income, including interest, dividends and
discount accruals, and capital appreciation.
 
  The Portfolio will invest in the following investment sectors:
 
    (1) Common stocks, convertible debentures and convertible preferred
  stock, and other equity investments, including the types of securities in
  which the Growth & Income and Large Cap Growth Portfolios invest;
 
    (2) Bonds and other fixed income securities with maturities generally in
  excess of twelve months, including the types of securities in which the
  Sovereign Bond Portfolio invests; and
 
    (3) Money market instruments, such as U.S. government obligations,
  certificates of deposit and commercial paper, and other debt securities
  with maturities generally not in excess of twelve months, including the
  types of securities in which the Money Market Portfolio invests.
 
  The sub-investment manager of this Portfolio (see "Management of the Fund,"
below) will make ongoing decisions as to the mix of investments of the
Portfolio among the three investment sectors in order to capitalize on short
and intermediate-term market trends and to improve the long-term overall
return of the Portfolio.
 
  Growth & Income Portfolio: The investment objective of the Growth & Income
Portfolio is to achieve intermediate and long-term growth of capital, with
income as a secondary consideration. This objective will be pursued by
investments principally in common stocks (and in securities convertible into
or with rights to purchase common stocks) of companies believed to offer
growth potential over both the intermediate and the long-term.
 
  The policy of the Portfolio is to diversify investments among a number of
companies without concentration in any particular industry. The Portfolio may
temporarily maintain a portion of its assets in cash or invest in preferred
stocks, non-convertible bonds, notes, government securities, or other fixed-
income securities. However, in pursuing its objective of capital growth, the
Portfolio's management may place emphasis on the selection of securities of
progressive companies with aggressive and experienced management.
 
  Although the Portfolio will not make a practice of short-term trading,
purchases and sales of securities will be made whenever believed necessary to
achieve the objective of the Portfolio without regard to resulting brokerage
costs.
 
  Equity Index Portfolio: The investment objective of the Equity Index
Portfolio is to provide investment results that correspond to the total return
of the U.S. market as represented by the Standard & Poor's 500
 
                                      24
<PAGE>
 
Composite Price Index (S&P 500) utilizing common stocks that are publicly
traded in the United States. The Portfolio attempts to achieve this objective
by investing in U.S. traded and denominated stocks to replicate the
characteristics of the S&P 500. For additional information about the S&P 500,
see "Investment Practices--The S&P 500" below.
 
  The Portfolio seeks to replicate the investment results of the S&P 500,
through passive investment management. The Portfolio will purchase the common
stock of those companies included in the S&P 500 in their capitalization
weighted proportions to attempt to replicate the aggregate risk
characteristics and industry diversification of the S&P 500. In this way, the
sub-investment manager attempts to minimize the degree to which the investment
results of the Portfolio differ from the results of the S&P 500.
 
  There is no fixed number of stocks in which the Portfolio will invest.
However, it is anticipated that under normal circumstances the Portfolio will
hold approximately 500 stocks. The Portfolio may purchase and sell stock index
futures, purchase options on stock indexes and purchase options on stock index
futures to maintain market exposure and manage cash flows. The Portfolio may
also invest in Standard & Poor's Depository Receipts. The Portfolio may
temporarily maintain cash balances for liquidity purposes or pending
investment, in short-term high quality debt instruments, including commercial
paper, bank obligations and U.S. Government securities.
 
  As changes are made to the S&P 500 during the year, they will be reflected
in the Portfolio as soon as deemed advisable. The Portfolio will, to the
extent feasible, remain fully invested. The Portfolio's ability to match the
performance of the S&P 500 will be affected to some extent by the size and
timing of cash flows into and out of the Portfolio. The Portfolio will be
managed to reduce such effects. Although the Portfolio will attempt to achieve
a high correlation with the target S&P 500, it cannot guarantee that a high
correlation will be achieved. Other factors that will affect the Portfolio's
ability to approximate the target index return are: commission expenses, other
operating expenses, the size of the bid-ask spread associated with stocks that
are traded in the over-the-counter market, portfolio management expenses
incurred, and the degree of success of the techniques employed by the
Portfolio's sub-investment manager.
 
  Large Cap Value Portfolio: The investment objective of the Large Cap Value
Portfolio is to provide substantial dividend income, as well as long-term
capital appreciation, through investment in the common stocks of established
companies believed to offer favorable prospects for increasing dividends and
capital appreciation. The Portfolio will invest primarily in the common stocks
of established companies paying above average dividends. Under normal
circumstances, at least 65% of the value of the Portfolio's total assets will
consist of equity securities of large capitalization ("large cap") companies.
The Fund's current definition of "large cap" companies is set forth below
under "Market Capitalization Risk."
 
  The Portfolio will tend to take a value approach and invest in stocks and
other securities that appear to be temporarily undervalued by various
measures, such as price/earnings ratios. The Portfolio will generally consider
companies with the following characteristics: established operating histories;
above average current dividend yields relative to the S&P 500 Index; low
price/earnings ratios relative to the S&P 500 Index; sound balance sheet and
other financial characteristics; and stock price relative to company's
underlying value measured by assets, earnings, cash flow, or business
franchises.
 
  Most of the assets will be invested in U.S. common stocks. However, the
Portfolio may also purchase other types of securities: for example, foreign
securities, convertible securities, money market securities and other short-
term securities, and warrants, when considered consistent with the Portfolio's
investment objective and program.

  Large Cap Growth Portfolio: The investment objective of the Large Cap Growth
Portfolio is above-average capital appreciation through the ownership of
common stocks (and securities convertible into or with rights to purchase
common stocks) of companies believed to offer above-average capital
appreciation opportunities. Current income is not an objective of the
Portfolio. In pursuing its investment objective, the Portfolio will generally
purchase securities of well-managed companies believed to offer growth
potential through their increasing earnings but will also invest in other
companies where unusual appreciation opportunities may exist.
 
  Under normal circumstances, at least 65% of the value of the Portfolio's
total assets will consist of equity investments in large capitalization
("large cap") companies. This is a non-fundamental policy that may be changed
without shareholder approval. The Fund's current definition of "large cap"
companies is set forth below under "Market Capitalization Risk."
 
  While this Portfolio generally will sell securities only after owning them
for more than six months, shorter term considerations may also govern the
purchase and sale of securities. Accordingly, the Portfolio may realize short-
term gains or losses as well as long-term gains or losses.
 
  Considering that the Portfolio will be aggressively managed and that the
investments which are believed to have the greatest growth potential may
present significant risks, an investment in this Portfolio involves a higher
degree of risk than more conservative large capitalization common stock funds
such as the Growth & Income and Equity Index Portfolios. In economic and
market environments that are considered favorable for achievement of capital
appreciation, the Large Cap Growth Portfolio will invest in securities more
volatile than the overall market. When poor market conditions exist, however,
the sub-investment manager may seek to reduce potential losses by holding
meaningful amounts of cash and short-term instruments, perhaps up to as much
as 50% of the Portfolio.
 
  Mid Cap Value Portfolio: The investment objective of the Mid Cap Value
Portfolio is to provide long-term growth of capital primarily through
investment in the common stocks of medium capitalization companies believed to
sell at a discount to their intrinsic value. The Portfolio may also invest in
larger or smaller issuers, although, under normal circumstances, at least 65%
of the value of its total assets will consist of equity investments in mid-cap
companies. The Fund's current definition of "mid cap" companies is set forth
below under "Market Capitalization Risk." The Portfolio seeks capital growth
through an investment approach that is intended to increase capital with the
intention of not subjecting the Portfolio to unreasonable risk.
 
  Its investment strategy is to invest in securities believed to be
undervalued based on strong fundamentals, including low price/earnings ratios,
strong balance sheet and financial positions, recent company restructuring
with the potential to realize hidden values, strong management, consistent
cash flow, or low price/book value.
 
  Most of the assets normally will be invested in U.S. common stocks. However,
the Portfolio may also purchase other types of securities: for example,
foreign securities, convertible securities, cash and short-term securities,
and warrants, when considered consistent with the Portfolio's investment
objective and program.
 
  Mid Cap Growth Portfolio: The investment objective of the Mid Cap Growth
Portfolio is to provide long-term growth of capital through a non-diversified
portfolio investing primarily in common stocks of medium capitalization ("mid
cap") companies. The Fund's current definition of "mid cap" companies is set
forth below under "Market Capitalization Risk." The Portfolio may also invest
in smaller or larger issuers, although, under
 
                                      26
<PAGE>
 
normal circumstances, at least 65% of the value of its total assets will
consist of equity investments in mid-cap companies. Realization of income is
not a significant investment consideration. Any income realized by the
Portfolio's investments will be incidental to its primary objective.
 
  The sub-investment manager takes a stock-by-stock approach to building the
Portfolio by seeking to identify individual companies with earnings growth
potential that may not be recognized by the market at large. Securities are
selected without regard to any defined industry sector or other similarly
defined selection procedure. For foreign securities, the Portfolio invests in
companies with earnings growth potential, regardless of country of
organization or place of principal business activity.
 
  Most of the assets normally will be invested in U.S. common stocks. However,
the Portfolio may also purchase other types of securities: for example,
foreign securities, convertible securities, preferred stocks, cash and short-
term securities, and warrants, when considered consistent with the Portfolio's
investment objective and program.
 
  Special Opportunities Portfolio: The investment objective of the Special
Opportunities Portfolio is to achieve long-term capital appreciation by
emphasizing investments in equity securities of issuers in various economic
sectors. This is a non-diversified Portfolio.
 
  The Portfolio seeks to achieve its investment objective by varying the
relative weighting of its portfolio securities among various economic sectors
based upon both macroeconomic factors and the outlook for each particular
sector. The sub-investment manager selects equity securities for the Fund from
various economic sectors, including, but not limited to, the following:
automotive and housing, consumer goods and services, defense and aerospace,
energy, financial services, health care, heavy industry, leisure and
entertainment, machinery and equipment, precious metals, retailing,
technology, transportation, utilities, foreign, and environmental. These
sectors may be modified at any time by the sub-investment manager without
notice.
 
  Under normal market conditions, at least 90% of the Portfolio's equity
investments will be in the equity securities of issuers in five or fewer of
the sectors. Subject to the Portfolio's policy of investing not more than 25%
of its total assets in any one industry, issuers in any one sector may
represent all of the Portfolio's assets. However, the Portfolio retains the
flexibility to invest its assets in a broader group of sectors in response to
changes in economic and market conditions. The Portfolio may not hold
securities of issuers in all of the sectors at any given time.
 
  In selecting securities, the sub-investment manager will determine the
allocation of assets among equity securities, fixed income securities, and
cash; the sectors that will be emphasized at any given time; the distribution
of securities among the various sectors; the specific industries within each
sector and the specific securities within each industry. In making the sector
analysis, the sub-investment manager considers the general economic
environment, the outlook for real economic growth in the United States and
abroad, trends and developments within specific sectors, and the outlook for
interest rates and the securities markets. A sector is a "special opportunity"
when in the opinion of the sub-investment manager the issuers in that sector
have a high earnings potential. In selecting particular issuers, the sub-
investment manager considers price/earnings ratios, ratios of market to book
value, earnings growth, product innovation, market share, management quality,
and capitalization.
 
  The Portfolio's investments may include securities of both large widely-
traded companies and smaller, less well-known issuers. The Portfolio seeks
investments in growth companies that either (1) occupy a dominant
 
                                      27
<PAGE>
 
position in a small emerging or established industry or (2) have a
significant, growing market share in a large, fragmented industry.
 
  The equity securities in which the Special Opportunities Portfolio invests
consist primarily of common stocks of U.S. and foreign issuers but may also
include preferred stocks, convertible debt securities and warrants.
 
  The Portfolio may also invest in the following fixed income securities: U.S.
Government securities and convertible and non-convertible corporate preferred
stocks and debt securities. The Portfolio may purchase fixed income debt
securities with stated maturities of up to thirty years. The corporate fixed
income securities in which the Portfolio may invest will be of investment
grade quality (as defined above under "Sovereign Bond Portfolio").
 
  Real Estate Equity Portfolio: The investment objective of the Real Estate
Equity Portfolio is to provide above-average income and long-term growth of
capital by investment principally in equity securities of companies in the
real estate and related industries.
 
  Under ordinary economic conditions, the major part of the Portfolio's
investments will be invested in the equity investments of equity real estate
investment trusts which own commercial and multi-family residential real
estate, commercial property companies and companies primarily engaged in the
real estate business, such as real estate development companies, commercial
and residential brokerage companies and natural resource companies.
 
  Investments may also be made in companies with activities related to the
real estate industry, such as mortgage real estate investment trusts which
make construction, development and long-term mortgage loans; financial
institutions, including thrift institutions and mortgage banking companies,
which originate or service mortgage loans; manufacturers and distributors of
building supplies, manufactured housing and mobile homes; and hotel companies,
entertainment companies, retailers, railroads and other companies engaged in
non-real estate businesses but whose real estate holdings are significant in
relation to the market value of their common stock.
 
  The securities purchased will be principally common stocks (and securities
convertible into or with rights to purchase common stocks) but a portion of
the Portfolio may be invested in preferred stock, in commercial mortgage
securities (debt obligations secured by commercial property) and in
collateralized mortgage obligations (mortgage pass-through securities secured
by commercial mortgage pools) which will primarily be of investment grade
quality as defined above under "Sovereign Bond Portfolio". The Portfolio may
also invest in master limited partnerships from time to time.
 
  Although the Portfolio will not make a practice of short-term trading,
purchases and sales of securities will be made whenever believed necessary to
achieve the objectives of the Portfolio, giving secondary consideration to
resulting brokerage costs.
   
  Small/Mid Cap CORE Equity Portfolio: The investment objective of the
Small/Mid Cap CORE Equity Portfolio is to achieve long-term growth of capital
through a broadly diversified portfolio of securities of U.S. issuers which
are included in the Russell 2500 Index at the time of investment. The sub-
investment manager utilizes optimization techniques (described below) to seek
to maximize the Portfolio's expected return, while maintaining a risk profile,
style, capitalization and industry characteristics similar to the Russell 2500
Index. At least 90% of total assets will be invested in equity securities of
U.S. issuers, including certain foreign issues     
 
                                      28
<PAGE>
 
   
traded in the U.S. and that comply with U.S. accounting standards. Under
normal circumstances at least 65% of this Portfolio's total assets will
consist of equity investments in small capitalization ("small cap") or medium
capitalization ("mid cap") companies. The Fund's current definitions of "small
cap" and "mid cap" companies are set forth below under "Market Capitalization
Risk."     
   
  Within these general parameters, the Portfolio's investments are selected
using a "Computer-Optimized, Research-Enhanced ("CORE") investment process. An
important component of the CORE process is a rigorous computerized system for
forecasting returns in the U.S. equity market, and returns on individual
equity securities, according to fundamental investment characteristics. This
proprietary computerized system incorporates measures of value, growth,
momentum and risk (e.g., book/price ratio, earnings/price ratio, price
momentum, price volatility, consensus growth forecasts, earnings estimate
revisions, and earnings stability). All of these factors have been shown to
significantly impact the performance of the securities and markets they were
designed to forecast. The weightings that the computerized system assigns to
these factors are derived using a statistical formulation that considers each
factor's historical performance in different market environments. Moreover,
the computerized system is designed to evaluate each security using only the
factors that are statistically related to returns in the anticipated market
environment. Because it includes many disparate factors, the sub-investment
manager believes that this computerized system is broader in scope and
provides more thorough evaluation than most conventional quantitative models.
Securities and markets ranked highest by this computerized system do not have
one dominant investment characteristic; rather, they possess an attractive
combination of investment characteristics.     
   
  The sub-investment manager seeks to "enhance" the above described
computerized analysis of a security with more traditional types of research
provided by the Goldman Sachs Global Investment Research Department or other
appropriate sources. The resulting evaluations reflect analysts' judgments as
to the investment merits of each specific security and incorporate economic
outlook, valuation, risk and a variety of other factors.     
   
  Securities owned by this Portfolio will generally be sold when the sub-
investment manager believes that the market price fully reflects or exceeds
the securities fundamental valuation or when more attractive investments are
identified. By employing both a quantitative (i.e., "Computer-Optimized") and
a qualitative (i.e., "Research-Enhanced") method of selecting securities,
Small/Mid Cap CORE Equity Portfolio seeks to capitalize on the strengths of
each discipline.     
   
  Although most of the assets normally will be invested in U.S. common stocks,
the Portfolio may also purchase other types of securities: for example,
foreign securities, convertible securities, preferred stocks, and warrants,
when considered consistent with the Portfolio's investment objective and
program. The Portfolio will invest in equity securities of foreign issuers
only if traded in the U.S. and if the issuer complies with U.S. accounting
standards. The Portfolio will invest only in those fixed income securities
that are considered cash equivalents.     
 
  Small Cap Value Portfolio: The investment objective of the Small Cap Value
Portfolio is to provide long-term growth of capital by investing in a well
diversified portfolio of equity securities of small capitalization companies
exhibiting value characteristics. Under normal circumstances, the Portfolio
will invest at least 65% of the value of its total assets in the equity
securities of U.S. small cap companies. The Fund's current definition of
"small cap" companies is set forth below under "Market Capitalization Risk."
However, the Portfolio may invest to a lesser degree in equity securities of
companies whose capitalizations exceed that of small cap companies. The
Portfolio normally will be highly diversified, containing 150 to 250
securities.
 
 
                                      29
<PAGE>
 
  In managing the Portfolio, the sub-investment manager will apply a
combination of quantitative strategies and traditional stock selection methods
to a very broad universe of stocks of small companies in order to uncover the
best possible values. Typically, over 2,500 stocks will be examined
quantitatively for their exposure to certain factors. The sub-investment
manager has identified specific factors which it believes are helpful in
selecting equities which may provide superior performance. These factors may
include earnings-to-price ratios, book value-to-price ratios, earnings
estimate revision momentum, relative market strength compared to competitors,
inventory/sales trend and financial leverage. Once an initial suggested
portfolio is generated through an optimization process, traditional
fundamental analysis is used to provide a final review before stocks are
selected for purchase for the Portfolio.
 
  Most of the assets normally will be invested in U.S. common stocks. However,
the Portfolio may also purchase other types of securities: for example,
foreign securities, convertible securities, cash and short-term securities,
and warrants, when considered consistent with the Portfolio's investment
objective and program.
 
  Small Cap Growth Portfolio: The investment objective of the Small Cap Growth
Portfolio is to provide long-term growth of capital through a diversified
portfolio investing primarily in common stocks of small capitalization ("small
cap") emerging growth companies. The potential for growth of capital is the
sole basis for selection of securities, with current income not a factor in
the security selection process.
 
  The management expects that common stocks of rapidly growing smaller
companies that tend to be in an emerging growth stage of development generally
offer the most attractive growth prospects. However, the Portfolio may also
invest in equity securities of larger, more established companies that the
management believes offer superior growth potential. Nevertheless, under
normal circumstances, at least 65% of the value of the Portfolio's total
assets will consist of equity investments in small cap companies. The Fund's
current definition of "small cap" companies is set forth below under "Market
Capitalization Risk." The Portfolio will be invested in securities that
management believes will offer growth potential higher than average for all
companies.
       
  Most of the assets normally will be invested in U.S. common stocks. However,
the Portfolio may also purchase other types of securities: for example,
foreign securities, convertible securities, cash and short-term securities,
and warrants, when considered consistent with the Portfolio's investment
objective and program.
   
  Global Equity Portfolio: The investment objective of the Global Equity
Portfolio is to achieve long-term growth of capital through a diversified
portfolio of marketable securities, primarily equity securities. The Portfolio
invests on a worldwide basis in equity securities of companies which are
incorporated in the U.S. or in foreign countries. Income is an incidental
consideration.     
   
  The Portfolio invests in companies that the Portfolio's sub-investment
manager believes will benefit from global economic trends, promising
technologies or products and specific country opportunities resulting from
changing geopolitical, currency or economic relationships. It is expected that
investments will be spread broadly around the world. The Portfolio will be
invested usually in securities of issuers located in at least three countries,
one of which may be the U.S. The Portfolio may be invested 100% in non-U.S.
issues, and for temporary defensive purposes may be invested 100% in U.S.
issues, although under normal circumstances it is expected that both foreign
and U.S. investments will be represented in this Portfolio.     
   
  It is expected that investments will include companies of varying size as
measured by assets, sales or capitalization. The Portfolio generally invests
in equity securities of established companies listed on U.S. or foreign
securities exchanges, but also may invest in securities traded over-the-
counter. It also may invest in debt     
 
                                      30
<PAGE>
 
   
securities convertible into common stock, convertible and non-convertible
preferred stock, and fixed-income securities of governments, government
agencies, supranational agencies and companies when the sub-investment manager
believes the potential for appreciation will equal or exceed that available
from investments in equity securities. These debt and fixed-income securities
will be predominantly of investment grade quality (as defined below under
"Sovereign Bond Portfolio"). The Portfolio may not invest more than 5% of its
total assets in debt securities of the type commonly referred to as "high
yield" or "junk" bonds. See "Risks of Other Debt Securities" below.     
 
  International Balanced Portfolio: The investment objective of the
International Balanced Portfolio is to provide maximum total U.S. dollar
return, consisting of capital appreciation and current income. The Portfolio
seeks to achieve its objective by pursuing active asset allocation strategies
across non-U.S. equity and fixed income markets and active security selection
within each market. This is a non-diversified portfolio.
 
  The sub-investment manager's investment perspective for the Portfolio is to
determine fundamental value (i.e., whether an investment is fairly priced)
based on long-term sustainable future cash flows associated with given asset
classes and securities. The sub-investment manager will focus on comparing
current market prices to fundamental values, rather than on either forecasts
of future price changes or extrapolations of historical price relationships.
In determining fundamental value, the sub-investment manager takes into
consideration broadly based indices representing asset classes or markets and
various economic variables such as productivity, inflation and global
competitiveness. The valuation of asset classes reflects an integrated,
fundamental analysis of non-U.S. markets. The sub-investment manager believes
that, over the long term, investing across non-U.S. equity and fixed income
markets based upon discrepancies between market prices and fundamental values
may achieve enhanced return.
 
  It is expected that the Portfolio will invest its assets primarily in
developed equity markets other than the U.S. and in developed fixed income
markets other than the U.S. and to a lesser extent invest in equity and debt
securities of issuers in emerging markets. Under normal circumstances, fixed
income senior securities will constitute at least 25% of the value of the
Portfolio's total assets and the Portfolio will invest in issuers of at least
three different countries other than the United States.
   
  International Equity Index Portfolio: The investment objective of the
International Equity Index Portfolio is to provide investment results that
correspond to the total return of the major developed international (non-U.S.)
equity markets as represented by the MSCI EAFE GDP Index. This is the Gross
Domestic Product Weighted Morgan Stanley Capital International Europe,
Australasia and Far East (Free) Index, which is a broad-based benchmark made
up of more than 1,000 companies in Europe and the Pacific Rim. The MSCI EAFE
GDP Index is constructed by Morgan Stanley Capital International (MSCI), which
chooses countries commonly known as developed markets and weights them in the
index based on their Gross Domestic Product (GDP). Within each country, stocks
are weighted by their market capitalization. Most of the largest companies
listed on each country's stock exchange, by market value, are included in the
MSCI EAFE GDP Index for diversification purposes. For additional information
about this index, see "Investment Practices--The MSCI EAFE GDP Index" below.
    
          
  The Portfolio attempts to track the capital appreciation and dividend income
of the Index by investing in a representative portion of the stocks which
matches as closely as possible the characteristics of the stocks which
comprise the Index. The Portfolio will also invest in stock index futures. The
Portfolio will attempt to achieve a correlation between the performance of its
Portfolio and that of MSCI EAFE GDP Index of at least 0.90, without taking
into account fees and expenses. A perfect correlation would be 1.00.     
 
                                      31
<PAGE>
 
   
  The Portfolio's ability to track the performance of the Index will depend to
some extent on the size and timing of cash flows into and out of the
Portfolio, as well as on the level of the Portfolio's expenses, and the
capability of the sub-investment manager to select a representative sample of
the securities included in the Index. To the extent that the size of the
Portfolio's assets limits the number of issues that the Portfolio can
purchase, or is relatively small in relation to cash flows, there is more
potential for deviation from the MSCI EAFE GDP Index's performance than at
higher asset levels.     
   
  The Portfolio normally invests at least 65% of its total assets in foreign
equity securities, consisting of common stocks (including American Depository
Receipts) and preferred stocks, securities convertible to common stock
(provided they are traded on an exchange or over-the-counter), warrants and
receipts. No more than 10% of the Portfolio's assets will be held in cash or
cash equivalents. The Portfolio may invest up to 20% of its net assets at time
of purchase in securities of emerging international markets, such as Mexico,
Chile and Brazil, either directly through local exchanges, through publicly-
traded closed-end country funds or through "passive foreign investment
companies." A substantial portion of the Portfolio's assets will be
denominated in foreign currencies. See "Risks of Foreign Securities" below.
       
  MSCI EAFE GDP Index is a registered service mark of Morgan Stanley Capital
International, which does not sponsor and is not in any way affiliated with
the Fund. Inclusion of a security in the Index in no way implies an opinion as
to its attractiveness or appropriateness as an investment.     
 
  International Equities Portfolio: The investment objective of the
International Equities Portfolio is to achieve long-term growth of capital by
investing primarily in foreign equity securities.
 
  Under normal circumstances, at least 80% of the Portfolio's total assets
will be invested in equity securities of issuers located in various countries
around the world. Generally, the Portfolio will contain securities of issuers
from at least three countries other than the United States. The Portfolio
normally will invest substantially all of its assets in equity securities,
such as common stock, preferred stock and securities convertible into common
and preferred stock. However, if deemed advisable by the sub-investment
managers, the Portfolio may invest in any other type of security, including
warrants, bonds, notes and other debt securities (including Eurodollar
securities) or obligations of domestic or foreign governments and their
political subdivisions, or domestic or foreign corporations. It is the
intention of the Portfolio generally to invest in debt securities only for
defensive purposes.
 
  The Portfolio will maintain a flexible investment policy and will invest in
a diversified portfolio of securities of companies and governments located
throughout the world. In making the allocation of assets among various
countries and geographic regions, the sub-investment managers ordinarily
consider such factors as prospects for relative economic growth among foreign
countries; expected levels of inflation and interest rates; government
policies influencing business conditions; and other pertinent financial, tax,
social, political and national factors--all in relation to the prevailing
prices of the securities in each country or region.
 
  In choosing investments for the Portfolio, the sub-investment managers
generally look for companies whose earnings show a strong growth trend or
companies whose current market value per share is undervalued. The Portfolio
will not restrict its investments to any particular size company and,
consequently, the Portfolio may include the securities of small and relatively
less well-known companies.
 
  International Opportunities Portfolio: The investment objective of the
International Opportunities Portfolio is to provide capital appreciation
through investment in common stocks of primarily well-established non-United
States companies. The Portfolio expects to diversify broadly among countries
throughout the world,
 
                                      32
<PAGE>
 
including developed countries, newly-industrialized countries and to a
moderate degree in emerging markets. The Portfolio expects, under normal
circumstances, to invest substantially all of its assets in common stocks
outside the United States. However, the Portfolio may also invest in a variety
of other equity-related securities, such as common stocks, preferred stocks,
warrants, and convertible securities, as well as money market and short-term
securities.
 
  In determining the appropriate distribution of investments among various
countries and geographic regions, the sub-investment manager ordinarily
considers the following factors: prospects for relative economic growth
between foreign countries; expected levels of inflation; government policies
influencing business conditions; the outlook for currency relationships; and
the range of individual investment opportunities available to international
investors.
 
  In analyzing companies for investment, the sub-investment manager ordinarily
looks for one or more of the following characteristics: an above average
earnings growth per share; high return on invested capital; a healthy balance
sheet; sound financial and accounting policies and overall financial strength;
strong competitive advantages; effective research and product development and
marketing; efficient service; pricing flexibility; strength of management; and
general operating characteristics which will enable the companies to compete
successfully in their market place. While current dividend income is not a
prerequisite in the selection of portfolio companies, the companies in which
the Portfolio invests normally will have a record of paying dividends, and
will generally be expected to increase the amounts of such dividends in future
years as earnings increase.
 
  Most of the assets normally will be invested in non-U.S. equity-related
securities. However, the Portfolio may also purchase other types of
securities: for example, domestic securities, cash and short-term securities,
when considered consistent with the Portfolio's investment objective and
program.
   
  Emerging Markets Equity Portfolio: The investment objective of the Emerging
Markets Equity Portfolio is capital appreciation which, under normal
conditions, it seeks by investing at least 65% of its total assets in equity
securities of emerging markets companies. Under normal conditions, the
Portfolio maintains investments in at least six emerging markets countries at
all times and invests no more than 35% of its total assets in any one emerging
markets country.     
   
  The sub-investment manager currently regards the following to be emerging
markets countries: Latin America (Argentina, Brazil, Chile, Colombia, Costa
Rica, Jamaica, Mexico, Peru, Trinidad and Tobago, Uruguay and Venezuela); Asia
(Bangladesh, China, India, Indonesia, Korea, Malaysia, Pakistan, the
Philippines, Singapore, Sri Lanka, Taiwan, Thailand and Vietnam); southern and
eastern Europe (Czech Republic, Greece, Hungary, Kazakistan, Poland, Portugal,
Romania, Russia, Slovakia, Slovenia, Turkey, and the Ukraine); the Middle East
(Israel and Jordan); and Africa (Egypt, Ghana, Ivory Coast, Kenya, Morocco,
Nigeria, South Africa, Tunisia and Zimbabwe). In the future the Portfolio may
invest in other emerging markets countries. The Portfolio considers a company
to be an emerging market company if its securities are principally traded in
the capital market of an emerging market country; it derives at least 50% of
its total revenue from either goods produced or services rendered in emerging
market countries or from sales made in such emerging market countries,
regardless of where the securities of such companies are principally traded;
or it is organized under the laws or and has a principal office in an emerging
market country.     
   
  This Portfolio uses a proprietary, quantitative asset allocation model
created by the sub-investment manager. This model employs mean-variance
optimization, a process used in developed markets based on modern portfolio
theory and statistics. Mean-variance optimization helps determine the
percentage of assets to invest in each country to maximize expected returns
for a given risk level. The Portfolio's aims are to invest in those countries
    
                                      33
<PAGE>
 
   
that are expected to have the highest risk/reward trade-off when incorporated
into a total portfolio context. This "top-down" country selection is combined
with "bottom-up" fundamental industry analysis and stock selection based on
original research and publicly available information and company visits.     
   
  This Portfolio invests primarily in common stock, but also may invest in
other types of equity and equity derivative securities (such as convertible
debt). This includes certain debt securities issued by the governments of
emerging markets countries that are, or may be eligible for, conversion into
investments in emerging markets companies under debt conversion programs
sponsored by such governments. It may invest up to 35% of its total assets at
the time of purchase in debt securities, including up to 5% in debt securities
rated below investment grade (as defined under "Sovereign Bond Portfolio"
below).     
   
  Investors in this Portfolio should expect greater fluctuations in share
price and total return compared with less aggressive funds. These
fluctuations, whether positive or negative, may be sharp and unanticipated.
See "Risks of Foreign Securities," below.     
 
  Short-Term U.S. Government Portfolio: The investment objective of the Short-
Term U.S. Government Portfolio is to provide a high level of current income
consistent with the maintenance of principal, through investment in a
portfolio of short-term U.S. Treasury securities and U.S. Government agency
securities.
 
  The Portfolio will invest substantially in high-quality U.S. Government
securities. These securities include U.S. Treasury notes, bills, and bonds
which are direct obligations of the U.S. Government and, as such, backed by
the full faith and credit of the United States. These securities also include
U.S. Government agency securities which also represent a low credit risk
because they are sponsored or guaranteed by Federal agencies or
instrumentalities; U.S. Government agency securities may or may not be backed
by the full faith and credit of the United States.
 
  The Portfolio will invest only in U.S. Government securities with maturities
of five years or less. The Portfolio can also make investments of less than
one year when, in the judgment of the sub-investment manager, potential
returns hold a relative advantage over longer maturities.
 
  The Portfolio would be suitable for investors seeking to enhance their
income and returns above those available from money market funds. In low
interest rate environments, the higher returns are attractive. In rising
interest rate environments, a short-term U.S. Government portfolio offers
greater stability and defensive characteristics than a longer maturity bond
account.
          
  Diversified Bond Index Portfolio: The initial investment objective of the
Diversified Bond Index Portfolio will be to provide investment results that
correspond to the total return and risk characteristics of the Lehman Brothers
Government/Corporate Index (the "Government/Corporate Index"). Over time, as
the portfolio reaches sufficient size, it is expected that the Portfolio will
seek to match the performance of the Lehman Brothers Aggregate Bond Index (the
"Aggregate Bond Index"), which is made up of the Government/Corporate Index,
the Lehman Brothers Mortgage-Backed Securities Index, and the Lehman Brothers
Asset-Backed Securities Index. The sub-investment manager estimates that,
under current conditions, this transition would occur when and if the
Portfolio's assets reach approximately $50 million.     
   
  Each of these indexes includes fixed rate debt issues rated investment grade
(as defined below under "Sovereign Bond Portfolio") by Moody's Investors
Service, Inc., or by Standard & Poor's Ratings Group if unrated by Moody's.
All issues have at least one year to maturity and an outstanding par value of
at least $100 million. For additional information about these indexes, see
"Investment Practices--the Lehman Brothers Government/Corporate and Aggregate
Bond Indexes."     
 
                                      34
<PAGE>
 
   
  The sub-investment manager will monitor to determine whether any of the
Portfolio's securities have ceased to meet any of these criteria, and, if so,
the Portfolio may dispose of such securities or retain them, regardless of
whether they have yet been removed from the relevant index. However, such
"ineligible" investments, together with cash and money market instruments may
not exceed 20% (and are not expected to exceed 10%) of the Portfolio's net
assets. Nor will more than 5% of the Portfolio's net assets comprise either
(a) cash or money-market instruments or (b) debt securities of the type
commonly referred to as "high yield" or "junk" bonds. See "Risks of Other Debt
Securities" below.     
   
  Within the foregoing parameters, the Portfolio will invest primarily in the
following obligations: (i) debt obligations issued or guaranteed by the United
States Government or its agencies or instrumentalities; (ii) debt obligations
issued by U.S. corporations; (iii) debt obligations issued or guaranteed by
foreign sovereign governments, municipalities, governmental agencies or
international agencies; (iv) mortgage-backed securities; (v) asset-backed
securities; and (vi) any other issues that are included in the
Government/Corporate or Aggregate Bond Index. Although the sub-investment
manager will manage the Portfolio in a passive manner, the Portfolio generally
will not hold all of the individual issues which comprise the
Government/Corporate or Aggregate Bond Index, because of the large number of
securities involved. Instead, the Portfolio will hold a representative sample
of the securities in the index, selecting issues so that certain critical
statistics of the Portfolio match those of the index to the greatest extent
feasible. Those factors include, but are not limited to: duration, cash flow
structure, industry sector, credit quality, and callability.     
   
  The Portfolio's ability to duplicate the performance of the relevant index
will depend to some extent on the size and timing of cash flows into and out
of the Portfolio, as well as on the level of the Portfolio's expenses, and the
capability of the sub-investment manager to select a representative sample of
the securities included in the index. To the extent that the size of the
Portfolio's assets limits the number of issues that the Portfolio can
purchase, or is relatively small in relation to cash flows, there is more
potential for deviation from the relevant index's performance than at greater
asset levels.     
       
  Sovereign Bond Portfolio: The investment objective of the Sovereign Bond
Portfolio is to provide as high a level of long-term total rate of return as
is consistent with prudent investment risk, through investment primarily in a
diversified portfolio of freely marketable debt securities. Total rate of
return consists of current income, including interest and discount accruals,
and capital appreciation.
 
  The Portfolio will purchase debt securities only as follows: (a) corporate
debt securities which are issued by United States or Canadian corporations,
(b) debt securities which are issued by other foreign corporations,
denominated in United States dollars, and publicly traded in the United States
or Europe and (c) governmental securities, domestic and foreign. It is the
Portfolio's present intent to purchase principally those governmental
securities which are issued or guaranteed by the United States government and
its agencies or instrumentalities and by the Government of Canada or any
Canadian province, municipality or governmental agency. Canadian and other
foreign securities will be purchased only if they are payable in United States
dollars. It is anticipated that, under normal conditions, the Portfolio will
not invest more than 25% of its total assets in foreign corporate securities
(excluding U.S. dollar denominated Canadian corporate securities).
 
  The Portfolio may not purchase securities unless the issuer or any company
on whose credit the purchase was based has a record of at least three years of
continuous operation, except for investments which in the aggregate taken at
cost do not exceed 5% of the Portfolio's total assets taken at market value.
 
                                      35
<PAGE>
 
  As set forth more fully in the Statement of Additional Information under
"Sovereign Bond Portfolio Securities," it is contemplated that at least 75% of
the Sovereign Bond Portfolio's debt securities (other than commercial paper)
will have a rating at the time of their purchase within the four highest
grades as determined by Moody's Investors Service, Inc., or Standard & Poor's
Corporation or be unrated debt securities considered to be of comparable
quality. Debt securities within the four highest grades are commonly referred
to as investment grade. Investments in lower-rated ("high yield") securities
are subject to greater risks of loss. The meanings of these ratings are
further discussed under "Types of Investment Instruments and Ratings--
Corporate Bond Ratings" in the Statement of Additional Information.
 
  When management believes it would be beneficial to the Portfolio, the
Sovereign Bond Portfolio intends to engage in short-term trading of its
securities. (See "Short-Term Trading" in the Statement of Additional
Information.)
 
  Strategic Bond Portfolio: The investment objective of the Strategic Bond
Portfolio is to provide a high total return consistent with moderate risk of
capital from a portfolio that invests in the debt obligations primarily of
U.S. issuers and to a more limited extent foreign issuers, including issuers
in emerging market countries. Total return will consist of income plus
realized and unrealized capital gains and losses. Although the net asset value
of the Portfolio will fluctuate, the Portfolio attempts to preserve the value
of its investments to the extent consistent with its objective.
 
  The sub-investment manager actively manages the Portfolio's duration, the
allocation of securities across market sectors, the allocation of securities
across countries, and the selection of specific securities within sectors
and/or countries. Based on fundamental, economic, and capital markets
research, the sub-investment manager adjusts the duration of the Portfolio in
light of market conditions and the sub-investment manager's interest rate
outlook. For non-U.S. investments, the Portfolio's assets are primarily
allocated to securities of developed countries.
 
  The sub-investment manager also actively allocates the Portfolio's assets
among the broad sectors of the fixed income market including, but not limited
to, debt obligations of governments, agencies and supranational organizations,
corporate securities, 144A securities, and asset-backed and mortgage-related
securities. Specific securities which the sub-investment manager believes are
undervalued are selected for purchase within the sectors using advanced
quantitative tools, analysis of credit risk, the expertise of a dedicated
trading desk, and the judgment of fixed income portfolio managers and
analysts.
 
  It is a current policy of the Portfolio that, under normal circumstances,
its assets primarily will consist of securities that are of at least
investment grade quality (as defined above under "Sovereign Bond Portfolio").
   
  High Yield Bond Portfolio: The investment objective of the High Yield Bond
Portfolio is to provide high current income and capital appreciation through
investing primarily in high yield (below investment grade) debt securities.
Under normal market and economic conditions, the Portfolio will invest at
least 65% of its assets in debt obligations considered to be below investment
grade, including high yield/high risk, preferred stock and convertible
securities. High yield/high risk debt securities, which are frequently
referred to as "junk bonds," are considered to be those securities rated Bal
or lower by Moody's Investors Service, or BB+ or lower by Standard & Poor's
Corporation, or unrated securities deemed to be of comparable credit quality
by the sub-investment manager. The meanings of these ratings are further
discussed under "Types of Investment Instruments and Ratings--Corporate Bond
Ratings" in the Statement of Additional Information. Generally, the
Portfolio's average maturity is expected to range between 3 and 15 years,
although there are no specific maturity restrictions.     
 
                                      36
<PAGE>
 
   
  The Portfolio may invest in debt obligations issued by foreign governments,
their agencies and instrumentalities, supranational entities, and companies
located outside of the United States. These will be primarily denominated in
U.S. dollars, and no more than 20% of the Portfolio's assets at the time of
purchase will be invested in issuers domiciled in countries whose credit
rating is below investment grade (e.g., emerging market countries). For
liquidity and flexibility or for defensive purposes in unusual market
conditions, the Portfolio may invest all or any portion of its assets in
investment-grade short term securities, cash or cash equivalents.     
   
  The Portfolio will be managed using a bottom-up decision-making process.
That is, decisions about which high yield/high risk bonds are to be bought,
held or sold will be based primarily on the investment merits of the
particular security. Top-down considerations (such as the macroeconomic
outlook or industry trends) will play an important role in new idea
generation, but the emphasis is on individual security selection based on
fundamental research. Such research will be performed largely at the sub-
investment manager by its staff of research analysts. Generally, the Portfolio
will not trade in securities for short-term profits but, when circumstances
warrant, securities may be sold without regard to the length of time held.
       
  Investors in this Portfolio should expect greater fluctuations in share
price, yield and total return, compared with less aggressive debt-oriented
funds. These fluctuations, whether positive or negative, may be sharp and
unanticipated. See also "Risks of Lower-Quality Instruments" under "Risks of
Other Debt Securities" below.     
 
  Money Market Portfolio: The investment objective of the Money Market
Portfolio is to provide maximum current income consistent with capital
preservation and liquidity. The Portfolio seeks to achieve this objective by
investing in a managed portfolio of high quality money market instruments
while ensuring that the weighted average to maturity of portfolio securities
does not exceed 90 days, including:
 
    (1) obligations issued or guaranteed as to principal or interest by the
  United States Government, or any agency or authority thereof;
 
    (2) obligations (including certificates of deposit and bankers
  acceptances) of U.S. banks and savings and loan associations which at the
  date of the investment have capital, surplus and undivided profits (as of
  the date of their most recent published financial statements) in excess of
  $100,000,000, including obligations of foreign branches of United States
  banks and United States branches of foreign banks if such banks meet the
  stated qualifications;
 
    (3) commercial paper which at the date of the investment is rated A-1 by
  Standard & Poor's Corporation, P-1 by Moody's Investors Service, Inc., or
  F-1 by Fitch's Investors Service or, if not rated, is issued by a company
  which at the date of the investment has an outstanding debt issue rated AAA
  or AA by Standard & Poor's or Aaa or Aa by Moody's; and
 
    (4) corporate obligations which at the date of the investment are rated A
  or higher by Standard & Poor's or A or higher by Moody's.
 
(For a more complete description of these money market obligations and ratings
, please refer to "U.S. Government Obligations," "Other Money Market Portfolio
Securities," "Commercial Paper Ratings," and "Corporate Bond Ratings" under
"Types of Investment Instruments and Ratings," in the Statement of Additional
Information).
 
  By limiting the maturity of its investments, the Money Market Portfolio
seeks to lessen the changes in the value of its assets caused by market
factors. As a fundamental investment policy, the Portfolio will endeavor to
maintain a constant net asset value of $10.00 per share. Nevertheless, no
assurances can be given that it will be able to do so or that the per share
net asset value of this Portfolio may not vary at times.
 
                                      37
<PAGE>
 
  The Portfolio, consistent with its investment objective, will attempt to
maximize yield through portfolio trading. For this reason, and because the
Portfolio's investments will have relatively short maturities, the Portfolio
may have a significant turnover.
 
                 BROKERAGE COMMISSIONS AND PORTFOLIO TURNOVER
   
  To the extent that brokerage commissions (or dealer "spreads" or "mark-ups")
are incurred in buying and selling portfolio securities, the rate of portfolio
turnover could affect each Portfolio's net asset value. The historical rates
of portfolio turnover for the Portfolios are set forth under "Financial
Highlights," above. The annual portfolio turnover rates for the Portfolios as
to which no historical information is yet available are expected to be
approximately the following percentages of those Portfolios' average daily net
assets:    % for the Small/Mid Cap CORE Equity Portfolio, 150% for the Global
Equity Portfolio, 15% for the International Equity Index Portfolio,   % for
the Emerging Markets Equity Portfolio, at least 30% for the Diversified Bond
Index Portfolio, and not more than 100% for the High Yield Bond Portfolio.
       
  Certain option and futures contract strategies which may be employed, in
varying degrees, by all of the Portfolios except the Growth & Income, Real
Estate Equity, Diversified Bond Index, and Money Market Portfolios can
increase the turnover rate and commission expenses and entail other risks to
those Portfolios employing such strategies. See "Investment Practices," below.
    
                                 RISK FACTORS
   
  The difference in objectives, policies, and practices of the various
Portfolios can be expected to affect each Portfolio's investment return as
well as the degree of financial and market risks to which each Portfolio is
subject. Financial risk refers to the ability of an issuer of a debt security
to pay principal and interest on such security; and it refers to the earnings
stability and overall financial soundness of an issuer of an equity security.
Market risk refers to the volatility of the conditions in the securities
markets in general and, with particular reference to debt securities, how
changes in the overall level of interest rates affect their prices.     
 
  In addition to the general risks discussed in the paragraphs that follow,
risks relating to certain specific investment practices in which a Portfolio
may engage are discussed below under "Investment Practices" and under "Types
of Investment Instruments and Ratings" in the Statement of Additional
Information.
 
RISKS OF MONEY MARKET INSTRUMENTS
 
  The Money Market Portfolio invests exclusively in money market instruments;
all the other Portfolios may invest in these instruments to some extent. Money
market instruments generally do not have maturities that exceed thirteen
months. Such securities can include short-term paper such as certificates of
deposit and commercial paper, and U.S. government obligations and other debt
securities with maturities generally not in excess of thirteen months. Money
market instruments offer investors liquidity. Although money market
instruments are subject to decreases and increases in market value resulting
from changes in interest rates, for the most part these changes are small due
to the instruments' short term to maturity.
 
                                      38
<PAGE>
 
RISKS OF OTHER DEBT SECURITIES
   
  The following Portfolios are primarily invested in non-money market debt
securities: the Short-Term U.S. Government, Diversified Bond Index, Sovereign
Bond, Strategic Bond, and High Yield Bond. The Managed, Emerging Markets
Equity, and International Balanced Portfolios can vary their holdings of these
securities within a broad range. All the other Portfolios (except the Money
Market Portfolio) may invest in these securities to some extent.     
 
  Interest Rate Risk: In general, debt securities having longer maturities
than money market instruments have exposure to interest rate risk. Changes in
generally prevailing market interest rates alter a debt security's market
value and introduce volatility into the rate of return of a Portfolio that
invests in such securities. This sensitivity of the market value of a debt
security to changes in interest rates is generally related to the duration of
the instrument. The market value of a shorter-term fixed income security is
generally less sensitive to interest rate moves than that of a longer-term
security. The interest rate risk of the Short-Term U.S. Government Portfolio,
although moderate, is well below that of traditional intermediate or long-term
bond portfolios.
   
  Credit Risk: The value of a fixed income security may also change as a
result of market perceptions regarding its default or credit risk, defined as
the ability of the borrower to repay its debts. The market value of a fixed
income security can fall when the market perceives the borrower to be less
credit worthy. Conversely, the market value of a fixed income security can
increase due to its borrower being perceived as financially stronger. All
Portfolios that invest in non-money market debt securities may have some
exposure to credit risk. The Short-Term U.S. Government and Money Market
Portfolios have negligible exposure to credit risk.     
   
  Risk of Lower-Quality Instruments: High-yield/high-risk bonds (or "junk"
bonds) are debt securities rated below investment grade as defined above under
"Investment Objectives and Policies--Sovereign Bond Portfolio." The value of
lower rated securities generally is more subject to credit risk than is the
case for higher rated securities, and their values tend to respond more to
changes in generally prevailing interest rates. Issuers of high yield/high
risk securities are typically in weak financial health and their ability to
pay back principal and interest on the bonds they issue is uncertain. Some of
these issuers may be in default or bankruptcy. Compared with issuers of
investment-grade bonds, they are more likely to encounter financial
difficulties and to be
       
materially affected by these difficulties when they do encounter them. Junk
bond markets may react strongly to adverse news about an issuer or the
economy, or to the perception or expectations of adverse news. These debt
securities may also have less liquid markets than higher rated securities.
       
  Investments in companies issuing high-yield securities are considered to be
more speculative than higher quality instruments. As such, these securities
typically pay a higher interest rate than investment grade securities. The
High Yield Bond Portfolio intends to invest primarily in these securities. The
other Portfolios most likely to invest a significant portion of their assets
in high-yield securities are the Managed, Large Cap Value, International
Balanced, Sovereign Bond, and Strategic Bond Portfolios. In contrast, the
Special Opportunities and Diversified Bond Index Portfolios will not invest in
debt securities that are not at least investment grade at the time of
purchase. However, all Portfolios (other than the Equity Index, Short-Term
U.S. Government, and Money Market Portfolios) that invest in debt securities
may at times have some exposure to high yield securities.     
 
  Although not customarily referred to as "high yield" securities or "junk
bonds," debt securities that fall in the lowest rating within the investment
grade category are considered medium grade securities that have some
speculative characteristics. Accordingly, to a lesser degree, they may present
the same risks discussed above with respect to high yield securities.
 
                                      39
<PAGE>
 
   
  Prepayment Risk: Prepayment risk is the risk that a borrower of a debt
security repays an outstanding loan before it is due. Such prepayment is most
likely to occur when interest rates have declined and a borrower can refinance
the debt at a lower interest rate level. Most mortgage backed, asset backed,
other public bond debt securities and 144A securities are exposed to this
risk. U.S. Government securities have minimal exposure to this risk. Issuers
of public debt securities may be required to pay a penalty in order to
exercise this prepayment right. Generally, a Portfolio reinvests the proceeds
resulting from prepayments in a lower yielding instrument. This results in a
decrease in the Portfolio's current yield. The values of securities that are
subject to prepayment risk also tend to increase less in response to declining
interest rates and decrease more in response to increasing interest rates than
would the value of otherwise similar securities that do not have prepayment
features. The Portfolios most likely to invest a significant position of their
assets in debt securities with prepayment features are Managed, Real Estate
Equity, International Balanced, Emerging Markets Equity, Short-Term U.S.
Government, Diversified Bond Index, Sovereign Bond, Strategic Bond, and High-
Yield Bond Portfolios. However, all Portfolios that invest in debt securities
(other than the Money Market Portfolio) may at times have some exposure to
prepayment risk.     
   
  Risks of "Zero Coupon" Instruments: All of the Portfolios may, in varying
degrees, invest in debt instruments that provide for payment of interest at
the maturity date of the instrument rather than periodically over the life of
the instrument. The values such instruments tend to respond more to changes in
interest rates than do otherwise comparable debt obligations that provide for
periodic interest payments. The Portfolios most likely to invest a significant
amount of their assets in instruments that are subject to this volatility risk
are the Managed, Real Estate Equity, International Balanced, Emerging Markets
Equity, Short-Term U.S. Government, Diversified Bond Index, Sovereign Bond,
Strategic Bond, and High-Yield Bond Portfolios. However, all Portfolios that
invest in debt securities may at times have some exposure to this risk.     
 
RISKS OF EQUITY SECURITIES
   
  All of the Portfolios intend to invest to some degree in common stock or
other equity securities, except for the Short-Term U.S. Government,
Diversified Bond Index, Sovereign Bond, Strategic Bond, and Money Market
Portfolios. All of the Portfolios that invest in equity securities expect to
make such securities their primary investment (except for the Managed
Portfolio, which may nevertheless do so in the discretion of its sub-
investment manager). The Managed Portfolio and International Balanced
Portfolio, though investing in equity securities, expect under normal
conditions also to have a substantial amount of their assets invested in debt
obligations.     
 
  Equity Risk: Investments in common stock or other equity securities may
offer a higher rate of return than those in money market instruments and
longer term debt securities. However, the risks associated with investments in
equity securities may also be higher, because the investment performance of
equity securities depends upon factors which are difficult to predict. Such
factors include overall market price trends for securities and operating
results of particular issuers. The fundamental risk associated with any equity
portfolio is the risk that the value of the investments it holds might
decrease in value. Equity security values may fluctuate in response to the
activities of an individual company or in response to general market and/or
economic conditions. Historically, equity securities have provided greater
long-term returns and have entailed greater short-term risks than other
investment choices.
 
  Market Capitalization Risk: Another indication of the relative risk of a
common stock investment is defined by the size of the company, which is
typically referred to as its market capitalization. Market capitalization is
computed by multiplying current market price of a share of the company's stock
by the total
 
                                      40
<PAGE>
 
number of its shares outstanding. Investing in larger capitalization companies
generally involves a lesser degree of risk than investing in smaller
capitalization companies.
   
  Companies with market capitalizations of greater than $2 billion qualify as
large capitalization ("large cap") companies that are the primary focus of the
Large Cap Value and Large Cap Growth Portfolios. Companies with market
capitalizations of less than $1 billion qualify as small capitalization
("small cap") companies that are the primary focus of the Small Cap Value and
Small Cap Growth Portfolios. Companies qualify as medium capitalization ("mid
cap") companies that are the primary focus of the Mid Cap Value and Mid Cap
Growth Portfolios, if they have market capitalizations that range from $500
million to $6 billion. A company will continue to qualify as a large cap, mid
cap or small cap company even though, sometime after a Portfolio invests in
it, the company ceases to be within the definition.     
   
  The equity securities of the Managed, Growth & Income, Equity Index, Large
Cap Value, Large Cap Growth, Global Equity, and International Equity Index
Portfolios are generally expected to represent primarily companies that
qualify as large cap issuers. These Portfolios also may invest in the equity
securities of companies that qualify as small and mid cap issuers.     
   
  The equity securities of the Mid Cap Value, and Mid Cap Growth Portfolios
are generally expected to represent primarily companies that qualify as mid
cap issuers. These Portfolios also may invest in the equity securities of
companies that qualify as small or large cap issuers.     
 
  The equity securities of the Real Estate Equity Portfolio are generally
expected to represent primarily companies that qualify as mid cap issuers. The
Portfolio also may invest significant amounts in the equity securities of
companies that qualify as small cap or mid cap issuers.
   
  The equity securities of the Small/Mid Cap CORE Equity and Emerging Markets
Equity Portfolios are generally expected to represent companies that are small
cap and mid cap issuers. These Portfolios also may invest in the equity
securities of companies that qualify as large cap issuers.     
   
  Small Cap Risk: The very nature of investing in the equity securities of
smaller companies involves greater risks and potential rewards than investing
in larger, more established companies. Emerging growth companies often have
limited product lines, markets or financial resources, and they may depend
upon a small group of inexperienced managers. Investments in such companies
can be both more volatile and more speculative. These securities may have
limited marketability and are subject to more abrupt or erratic market
movements than securities of larger companies or the market in general. The
Small Cap Value and Small Cap Growth Portfolios are generally expected to
invest primarily in equity securities of companies that qualify as small cap
issuers. Although these Portfolios also may invest significant amounts in the
equity securities of companies that qualify as mid cap issuers, it is expected
that they would only rarely invest in the equity securities of companies that
qualify only as large cap issuers.     
 
REAL ESTATE RISK
 
  Investments in the Real Estate Equity Portfolio will be affected by risks
related to the direct ownership of real estate, as well as by market risks due
to changes in interest rates and by the overall volatility of the equities
markets. The market value of shares in equity real estate investment trusts
and commercial property companies in particular is heavily dependent upon the
value of their underlying properties. Overbuilding, declines in local or
regional economic conditions, financial difficulties on the part of major
tenants and increases in real estate
 
                                      41
<PAGE>
 
   
taxes and operating expenses all could decrease the value of the real estate
investments. In addition to the Real Estate Portfolio, all of the other
Portfolios (except for the U.S. Short-Term Government and Money Market
Portfolios) may have some exposure to real estate risks through investments in
companies engaged in real estate related businesses or investments in debt
instruments secured by real estate.     
 
RISKS OF FOREIGN SECURITIES
   
  The following Portfolios invest primarily in foreign securities: the
International Balanced, International Equity Index, International Equities,
International Opportunities, and Emerging Markets Equity Portfolios. The
Managed, Special Opportunities, Global Equity, Strategic Bond, and High-Yield
Bond Portfolios can vary their holdings of these securities within a broad
range. All the other Portfolios can invest in these securities to some extent,
except for the Real Estate Equity and Short-Term U.S. Government Portfolios.
The Emerging Markets Equity Portfolio invests primarily in developing
countries commonly known as "emerging markets." To a lesser extent, the
Special Opportunities, Global Equity, International Balanced, International
Equity Index, International Equities, International Opportunities, Diversified
Bond, Strategic Bond, and High-Yield Bond Portfolios may also invest in such
emerging markets.     
 
  Currency Risk: Portfolios that invest in foreign securities typically buy
the local currency when they acquire foreign securities and sell the local
currency when they dispose of these securities. As long as Portfolios hold a
security denominated or quoted in a foreign currency, the security's value
will be affected by the value of the local currency relative to that of the
U.S. dollar. In other words, when Portfolios sell a foreign security, the
security's value may be worth more or less in U.S. dollars. Currency risk may
be greater in emerging markets. Strategies that some Portfolios may use to
manage their foreign currency exposure also present certain risks. See
"Foreign Currency Management Strategies," below.
 
  Political and Economic Risk: Foreign securities are subject to heightened
political and economic risks, particularly in underdeveloped or developing
countries, which may have relatively unstable governments and economies based
on only a few industries. Foreign governments may take over the assets or
operations of a company, may impose additional taxes, or may place limits on
the removal of the Portfolio's assets from that country. However, investments
in foreign securities also offer the opportunity to diversify equity holdings
and to invest in economies whose growth may outpace that of the United States.
 
  Regulatory Risk: Generally, there is less government supervision of foreign
markets. Foreign issuers generally are not subject to uniform accounting,
auditing, and financial reporting standards and practices applicable to
domestic issuers. There may be less publicly available information about
foreign issuers than domestic issuers. These risks may be greater in emerging
markets.
 
  Market Risk: Foreign securities markets, particularly those of
underdeveloped or developing countries, may be less liquid and more volatile
than domestic markets. Certain markets may require payments for securities
before delivery and delays may be encountered in settling securities
transactions. In some foreign markets, there may not be protection against
failures by other parties to complete transactions. There may be limited legal
recourse against an issuer in the event of a default on a debt instrument.
 
  Transaction Costs: Transaction costs of buying and selling foreign
securities, including brokerage, tax, and custody costs, are generally higher
than those involved in domestic transactions.
 
                                      42
<PAGE>
 
RISKS OF REALLOCATION
   
  The continual reallocation of assets among the major asset classes (e.g.,
stocks, bonds, and cash) involves the risk that the investment manager may
reduce the Portfolio's holdings in an asset class whose value increases
unexpectedly, or may increase the Portfolio's holdings in an asset class just
prior to it experiencing a loss of value. The Managed and International
Balanced Portfolios tend to exercise broad discretion in reallocating assets
across asset classes. The Strategic Bond Portfolio intends to exercise
discretion to reallocate assets across domestic and international fixed income
asset classes. All of the other Portfolios, with the exception of the Short-
Term U.S. Government and Money Market Portfolios, generally allow the sub-
investment manager some latitude to allocate across asset classes.
Nevertheless, this latitude is expected to be exercised to a lesser degree
than in the case of the Managed and International Balanced Portfolios.     
 
RISKS OF FULL INVESTMENT
   
  The Equity Index, International Equity Index, and Diversified Bond Index
Portfolios expect to invest substantially all of their assets in equity or
debt securities within their investment objectives and policies at all times.
Accordingly, these Portfolios may carry more risk in times of declining
markets than Portfolios that are more likely to adopt a defensive investment
posture in such circumstances by reallocating their assets in a manner
different from that contemplated by their primary investment objective and
policies. Except for the Short-Term U.S. Government and Money Market
Portfolios, all of the Portfolios have authority to assume such a defensive
position, and they may or may not do so, in the discretion of the sub-
investment managers. However, the Equity Index, International Equity Index,
and Diversified Bond Index Portfolios are less likely to assume such a
defensive position than any of such other Portfolios.     
 
RISKS OF NON-DIVERSIFIED PORTFOLIOS
   
  The Mid Cap Growth, Special Opportunities, and International Balanced
Portfolios are non-diversified Portfolios. A "non-diversified" portfolio has
the ability to take larger positions in a smaller number of issuers than
"diversified" portfolios. Because the appreciation or depreciation of a single
security may have a greater impact on the net asset value of a non-diversified
portfolio, its share price can be expected to fluctuate more than a comparable
diversified portfolio. Non-diversified Portfolios are less restricted in the
extent to which they may invest more than 5% of their assets in any issuer or
purchase more than 10% of the voting securities of any issuer. Because a
relatively high percentage of a non-diversified Portfolios' assets may be
invested in the obligations of a limited number of issuers, the value of these
Portfolios' shares may be more susceptible to any single economic, political,
or regulatory event, and to credit and market risks associated with a single
issuer, than would the shares of a diversified portfolio. Non-diversified
Portfolios, like the other Portfolios, are subject to certain federal income
tax law requirements that limit the amounts invested in a single issuer or in
a small group of issuers. See "Taxes" in the Statement of Additional
Information.     
 
                            INVESTMENT RESTRICTIONS
   
  The following is a abbreviated summary of certain restrictions on the
investments of each Portfolio's assets. (A more complete statement of these
and other restrictions is included in the Statement of Additional Information
under "Investment Restrictions.") No Portfolio will: (1) purchase real estate
or any interest in real estate, but investments of the type permitted in the
Real Estate Equity Portfolio are not deemed interests in real estate for the
purposes of this restriction; (2) make loans, other than as described below
under "Investment Practices--Portfolio Lending"; (3) invest in commodities,
commodity contracts, puts, or calls, except within certain limits, the
Managed, Equity Index, Large Cap Value, Large Cap Growth, Mid Cap Value, Mid
Cap Growth, Small/Mid     
 
                                      43

Cap CORE Equity, Small Cap Value, Small Cap Growth, Global Equity, Special
Opportunities, International Balanced, International Equity Index,
International Opportunities, Emerging Markets Growth, Short-Term U.S.
Government, Sovereign Bond, Strategic Bond, and High Yield Bond Portfolios;
(4) engage in the underwriting of securities of other issuers; (5) borrow
money except from banks as a temporary measure; (6) purchase securities
subject to delays or restrictions on resale, subject to exceptions for some
Portfolios; (7) purchase securities on margin; (8) invest for control
purposes; or (9) issue senior securities.     
   
  The Portfolios' investment restrictions described under "Investment
Restrictions" in the Statement of Additional Information are considered
"fundamental," in that they may not be changed without the approval of a
"majority" of outstanding voting shares of each affected Portfolio, as defined
in the Investment Company Act of 1940. Nor may the investment objectives and
policies that are set forth above under "Investment Objectives and Policies"
for the Managed, Growth & Income, Large Cap Growth, Special Opportunities,
Real Estate Equity, International Equities, Short-Term U.S. Government, and
Sovereign Bond Portfolios be changed without such a vote, unless otherwise
there indicated. Such investment objectives and policies of any other
Portfolio may, however, be changed without a vote, to the extent permitted by
its fundamental investment policies or restrictions and applicable law.     
 
                             INVESTMENT PRACTICES
 
REPURCHASE AGREEMENTS
   
  A repurchase agreement is a contract under which a Portfolio would acquire a
security for a relatively short period, e.g. 7 days, subject to the seller's
obligation to repurchase the security at a fixed time and price (representing
the Portfolio's cost plus interest). Repurchase agreements will be entered
into only with member banks of the Federal Reserve System and with "primary
dealers" in United States government securities. The Managed, Growth & Income,
Large Cap Growth, Real Estate Equity, Sovereign Bond and Money Market
Portfolios may not invest in repurchase agreements maturing in more than 7
days. No more than 15% (10% as to the Special Opportunities, International
Equities, and Short-Term U.S. Government Portfolios) of the net assets of any
other Portfolio will be invested in repurchase agreements maturing in more
than 7 days. All of the Portfolios may enter into repurchase agreements.     
   
  The Special Opportunities, Small Cap Growth, and International Equities
Portfolios, along with other registered investment companies having a
management contract with John Hancock Advisers, Inc. ("Advisers"), an indirect
wholly-owned subsidiary of John Hancock and sub-investment manager of the
Special Opportunities, Small Cap Growth, and International Equities
Portfolios, may participate in a joint repurchase agreement pursuant to an
exemptive order issued by the Securities and Exchange Commission ("SEC").
Aggregate cash balances are invested in one or more repurchase agreements,
whose underlying securities are obligations of the U.S. Government and/or its
agencies. Advisers is responsible for ensuring that the agreement is fully
collateralized at all times.     
   
  In addition, the Managed, Growth & Income, Large Cap Growth, Real Estate
Equity, Small Cap Value, International Equity Index, Sovereign Bond, and Money
Market Portfolios have entered into a joint trading account pursuant to an SEC
exemptive order. Under this arrangement, John Hancock is responsible for
investing the aggregate cash balances into one or more repurchase agreements,
as described above, or in other money market instruments. In the case of
repurchase agreements acquired pursuant to this arrangement, John Hancock is
responsible for ensuring that the agreement is fully collateralized at all
times. The other Portfolios also may participate in this joint trading account
advised by John Hancock or any similar joint trading account established
pursuant to an SEC exemptive order for investment companies advised by their
respective sub-investment managers.     
 
                                      44
<PAGE>
 
   
  Furthermore, Goldman Sachs Asset Management ("GSAM") has also received a
similar SEC exemptive order which permits GSAM to invest the aggregate cash
balances of the Small/Mid Cap CORE Equity Portfolio in one or more repurchase
agreements with other GSAM-advised mutual funds.     
   
USE OF OPTIONS ON SECURITIES BY THE MANAGED, EQUITY INDEX, LARGE CAP VALUE,
 LARGE CAP GROWTH, MID CAP VALUE, SMALL CAP VALUE, AND INTERNATIONAL
 OPPORTUNITIES PORTFOLIOS     
          
  Writing Exchange-Traded Covered Call Options. These Portfolios may write
"covered" call options on national securities exchanges. In such transactions,
the Portfolio receives an option "premium" in return for which it agrees to
sell specific securities held in its portfolio for a specified "exercise"
price at any time prior to the expiration period of the option. Although the
premium represents income to the Portfolio, the Portfolio in effect foregoes
the benefit of any appreciation in the price of the security in excess of the
exercise price during the option period.     
   
  Purchasing Exchange-Traded Protective Put Options. These Portfolios also may
purchase "protective" put options on national securities exchanges. In such
transactions, the Portfolio pays a "premium" for the right to sell particular
securities held by it for a specified "exercise" price at any time prior to
the expiration of the option period. If, over such period, the market value of
such underlying securities remains above the exercise price, the Portfolio
will, in effect, lose the premium it has paid. The Portfolio, however, avoids
the risk of loss on the underlying securities, to the extent that the market
value of the underlying security falls below the exercise price of the put
option.     
   
  Liquidity Risk. These Portfolios intend to write and purchase options only
if adequate liquidity exists. If for any reason a Portfolio cannot, however,
close out its open option position when deemed advisable, the Portfolio's
investment performance could be adversely affected.     
   
OTHER HEDGING STRATEGIES BY THE MANAGED, EQUITY INDEX, LARGE CAP VALUE, LARGE
 CAP GROWTH, MID CAP VALUE, SMALL CAP VALUE, AND INTERNATIONAL OPPORTUNITIES
 PORTFOLIOS     
          
  These Portfolios (other than the Equity Index Portfolio) may use exchange-
traded financial futures contracts and options thereon. These Portfolios will
use those instruments solely as a hedge to protect against possible changes in
interest rates, currency exchange rates, and stock prices. These Portfolios
also may purchase exchange-traded put or call options on stock indexes; but
again, solely for hedging purposes.     
   
  Similarly, the Equity Index Portfolio may purchase and sell stock index
futures and may purchase options on such futures contracts or on stock indexes
to maintain market exposure and manage cash flows.     
 
  Financial Futures Contracts. Financial futures contracts consist of interest
rate futures contracts, stock index futures contracts, and currency futures
contracts. An interest rate futures contract is a contract to buy or sell
specified debt securities at a future time for a fixed price. A stock index
futures contract is similar in economic effect, except that rather than being
based on specified debt securities, it is based on a specified index of
stocks. A currency futures contract is a contract to buy or sell a specified
currency at a future time for a fixed price.
   
  To hedge against the possibility that increases in interest rates may
adversely affect the market values of debt securities held by them, these
Portfolios (other than the Equity Index Portfolio) may enter into interest
rate futures sale contracts. Similarly, to hedge against the possibility that
interest rates or other factors may result in a general decline in prices of
equity securities of a type owned by them, these Portfolios may sell stock
index     
 
                                      45
<PAGE>
 
futures contracts. Assuming that any decline in the securities being hedged is
accompanied by a decline in the stock index or debt instrument chosen, the
futures sale contracts on that index or instrument may generate gains which
can wholly or partially offset any decline in the value of the Portfolio
securities which have been hedged.
   
  If they wish to hedge against the possibility of lower interest rates or
increases in equity prices, these Portfolios (other than the Equity Index
Portfolio) may purchase financial futures contracts. These Portfolios (as well
as the Equity Index Portfolio) may purchase futures contracts only when (a)
they intend to purchase securities or wish to establish or maintain market
exposure to securities that the Portfolio would be authorized to purchase and
(b) the values of such securities are expected to change by approximately the
same amount as the value of the futures contracts used to hedge them. When an
increase in the price of the securities is matched by a similar increase in
the value of the financial futures contracts, then the gains so generated will
achieve the Portfolio's objective for the hedge transaction.     
   
  Each of these Portfolios (other than the Equity Index Portfolio) may use
foreign currency futures contracts to manage their exposure to foreign
currencies. Foreign currency futures contracts could be used by a Portfolio
for this purpose in any manner that such Portfolio could use forward currency
contracts as described under "Foreign Currency Management Strategies" below.
       
  Options on Futures Contracts and on Stock Indexes. These Portfolios (other
than the Equity Index Portfolio) also may purchase options on appropriate
financial futures contracts and stock indexes in connection with the above
hedging strategies. Similarly, the Sovereign Bond Portfolio may purchase
options on financial futures contracts in connection with such strategies. An
option on a financial futures contract gives the purchaser the right to assume
a position in the underlying futures contract, and therefore can serve the
same hedging function as owning the futures contract directly. Purchase of an
option on a stock index has a very similar economic effect.     
   
  The purchase of a put or call option entails the payment by a Portfolio of a
non-refundable option premium. The use of options for hedging purposes is in
this sense more costly to the Fund than the purchase of futures contracts
directly. Nevertheless, if a Portfolio purchases an option, the maximum loss
it can suffer is the option premium plus commission costs. The potential loss
on a futures contract transaction is not so limited, because the Portfolio
would be obligated, as the case may be, to purchase or sell the full amount of
the securities or index amount on which the futures contract is based.     
   
  Limitations. None of the Managed, Equity Index, Large Cap Value, Large Cap
Growth, Mid Cap Value, Small Cap Value, or International Opportunities
Portfolios will enter into any financial futures contract or purchase any
option thereon, if, immediately thereafter, the total amount of its assets
required by commodities exchanges to be on deposit as margin to secure its
obligations under futures contracts, plus the amount of premiums paid by the
Portfolio for outstanding options to purchase futures contracts, exceeds 5% of
the market value of the Portfolio's total assets. For more information about
margin deposits, see "Financial Futures Contracts" in the Statement of
Additional Information.     
   
  Nor will any of the Managed, Large Cap Value, Large Cap Growth, Mid Cap
Value, or Small Cap Value Portfolios enter into any transaction in interest
rate, stock index or currency futures, or options thereon, or stock index
options, if the value of the securities being hedged by all of such
instruments would immediately thereafter be more than one-third of the value
of the Portfolio's total assets. Nor will any Portfolio consider as "hedging"
any transaction that is intended to leverage the Portfolio's investment
exposure to the type of security being hedged or to leverage the Portfolio's
currency exposure. Additional limitations may occur as a result of the tax
treatment of these hedging strategies.     
       
                                      46
<PAGE>
 
RISKS OF OPTIONS AND FUTURES TRANSACTIONS
   
  Risks of Hedging. If, after a Portfolio establishes a hedge position, the
value of the securities or currencies being hedged moves in the opposite
direction from that anticipated, the Portfolio as a whole will perform less
well than it would have had it not entered into the futures or options
positions.     
 
  The success of the Portfolios in using hedging techniques depends, among
other things, on the sub-investment manager's ability to predict the direction
and volatility of price movements in the futures or options markets, as well
as the securities markets and, in some cases, currency markets, and on the
sub-investment manager's ability to select the proper type, time and duration
of hedges. The sub-investment managers have limited experience in utilizing
these hedging techniques and there can be no assurance that these techniques
will produce their intended result. Also, use of these techniques may
complicate management of the Portfolios and make compliance with the
Portfolios' tax and other restrictions more difficult.
 
  The prices of the futures and options contracts used for hedging may not
vary as contemplated in relation to changes in the price of the securities or
currencies being hedged. Accordingly, there is a risk that transactions in
these instruments, if used by a Portfolio, may not in fact offset the impact
of adverse market developments in the manner or to the extent contemplated or
that such transactions may result in losses to the Portfolio which would not
be offset by gains with respect to corresponding portfolio securities owned or
to be purchased by that Portfolio. Although the Portfolios intend to establish
appropriate positions in these instruments only when there appears to be an
active market, there is no assurance that a liquid market will exist at a time
when the Portfolio seeks to close a particular futures or option position.
Hedging transactions also may be more, rather than less, favorable to a
Portfolio than originally anticipated.
   
  Other Risks for the Mid Cap Growth, Special Opportunities, Small/Mid Cap
CORE Equity, Small Cap Growth, Global Equity, International Balanced,
International Equity Index, Emerging Markets Equity, Short-Term U.S.
Government, Sovereign Bond, Strategic Bond, and High Yield Bond
Portfolios. These Portfolios may engage in types of options and futures
transactions not permitted to the Funds' other Portfolios, including over-the-
counter options, writing covered put options, and non-hedging (speculative)
transactions. Also, even as to options and futures transactions of a type that
are permitted to other Portfolios, these Portfolios are, in certain cases, not
as limited regarding the amount of their assets that may be so employed. To
the extent that these Portfolios exercise their broader authority to enter
into options and futures transactions, they may incur greater risks than the
other Portfolios.     
          
USE OF OPTIONS AND FUTURES BY THE MID CAP GROWTH, SPECIAL OPPORTUNITIES,
SMALL/MIDCAP CORE EQUITY, SMALL CAP GROWTH, GLOBAL EQUITY, INTERNATIONAL
BALANCED, INTERNATIONAL EQUITY INDEX, EMERGING MARKETS EQUITY, SHORT-TERM U.S.
GOVERNMENT, SOVEREIGN BOND, STRATEGIC BOND, AND HIGH YIELD BOND PORTFOLIOS
       
  Writing Exchange-Traded Covered Call Options and Purchasing Exchange-Traded
Protective Put Options. These Portfolios (other than the Sovereign Bond
Portfolio) may engage in the same transactions described above under "Writing
Exchange-Traded Covered Call Options" and "Purchasing Exchange-Traded
Protective Put Options."     
   
  Writing Covered Put Options. These Portfolios (other than the Sovereign Bond
Portfolio) may also write "covered" put options on securities. A put option
written by a Portfolio will be deemed to be "covered" if the Portfolio
maintains in a segregated account with its custodian cash, U.S. Government
securities or other high-grade liquid debt securities with a value at all
times at least equal to the exercise price of the put. Put and call     
 
                                      47
<PAGE>
 
   
options written by Portfolios will also be considered to be "covered" to the
extent that the Portfolio's liabilities under these options are fully offset
by its rights under put or call options purchased by the Portfolio. Although a
Portfolio receives a "premium" for writing a covered put option, it incurs the
risk that the put will be exercised and the Portfolio will be required to
purchase the securities subject to the put for a price that is higher than the
then-current market value of such securities.     
   
  Purchasing Other Put and Call Options on Securities and Securities Indexes.
These Portfolios (which for this purpose include the Sovereign Bond Portfolio)
may also purchase put and call options in the same types of transactions
described above under "Other Hedging Strategies by the Managed, Equity Index,
Large Cap Value, Large Cap Growth, Mid Cap Value, Small Cap Value, and
International Opportunities Portfolios."     
   
  The Mid Cap Growth, Special Opportunities, Small/Mid Cap CORE Equity, Small
Cap Growth, Global Equity, International Balanced, International Equity Index,
Emerging Markets Equity, Short-Term U.S. Government, Strategic Bond, and High
Yield Bond Portfolios also may, for other purposes, purchase put and call
options on indexes composed of securities in which those Portfolios may
invest.     
   
  The Mid Cap Growth, Small/Mid Cap CORE Equity, Small Cap Growth, Global
Equity, International Balanced, International Equity Index, Emerging Markets
Equity, Strategic Bond, and High Yield Bond Portfolios may also purchase put
and call options (in addition to those described above under "Purchasing
Exchange-Traded Protective Put Options") on securities in which they may
invest.     
   
  In purchasing a put or call option, a Portfolio may lose up to the entire
amount of the premium that it pays for the option, if the price of the
securities or index subject to the option moves adversely to the Portfolio's
position so that the option cannot be profitably exercised prior to its
expiration. None of these Portfolios may invest more than 5% of its total
assets, taken at market value at the time of investment, in call and put
options on domestic and foreign securities and indexes (excluding protective
put options purchased on securities and index options purchased as part of
hedging strategies).     
   
  Covered Put and Call Options Written on Securities Indexes by the Mid Cap
Growth, Special Opportunities, Small/Mid Cap CORE Equity, Small Cap Growth,
Global Equity, International Balanced, International Equity Index, Short-Term
U.S. Government, Strategic Bond, and High Yield Bond Portfolios. These
Portfolios (but not the Emerging Markets Equity or Sovereign Bond Portfolios)
may also write covered put or call options on indexes composed of securities
in which the Portfolio may invest, in any manner that such Portfolio would be
permitted to write such options on specific securities.     
   
  Using Options Traded Over-the-Counter or on Foreign Exchanges. These
Portfolios (which for this purpose include the Emerging Markets Equity
Portfolio but not the Sovereign Bond Portfolio) may also use options on
securities and options on indexes that are traded "over-the-counter" and on
foreign exchanges in any manner that they are otherwise permitted to use such
options. These Portfolios will engage in over-the-counter options only with
member banks of the Federal Reserve System and primary dealers in U.S.
Government securities. These Portfolios will treat purchased over-the-counter
options and assets used to cover written over-the-counter options as illiquid
securities. However, with respect to options written with primary dealers in
U.S. Government securities pursuant to an agreement requiring a closing
purchase transaction at a formula price, the amount of illiquid securities may
be calculated with reference to the formula price.     
   
  Using Futures Contracts and Options on Futures Contracts. These Portfolios
(which for this purpose include the Emerging Markets Equity and Sovereign Bond
Portfolios) may use futures contracts on securities or     
 
                                      48
<PAGE>
 
   
on market indexes, and options on such futures contracts, to hedge against
changes in securities prices, interest rates, and currency exchange rates
(including the techniques described above under "Other Hedging Strategies by
the Managed, Equity Index, Large Cap Value, Large Cap Growth, Mid Cap Value,
Small Cap Value, and International Opportunities Portfolios") or for non-
hedging (speculative) purposes. Such futures and options contracts will in all
cases be traded on U.S. commodity exchanges, boards of trade, or other
recognized exchanges and may be based upon various securities, financial
instruments or indexes thereof. None of these Portfolios may purchase, sell or
write futures contracts or options other than for "bona-fide" hedging purposes
(as defined by the U.S. Commodity Futures Trading Commission) if immediately
thereafter the Portfolio's initial margin deposits on such outstanding non-
hedging futures and options positions and the amount of premiums paid by the
Portfolio for such outstanding non-hedging options on futures contracts
exceeds 5% of the market value of the Portfolio's net assets. For the purpose
of this calculation, any amount by which an option is "in the money" at the
time of its purchase is excluded from the premium paid therefor.     
   
  There is no specific overall limit on the amount of these Portfolios that
may be exposed to the risks of financial futures contracts and options thereon
that are used for non-hedging purposes. Nevertheless (except through the
purchase of options, as discussed below) the Portfolios will not use these
techniques for purpose of "leveraging" the Portfolio's exposure to the
securities underlying any futures contract or option thereon or its exposure
to foreign currencies. Although this limitation does not apply to options on
futures contracts that are purchased by a Portfolio, the total amount of
premiums paid by a Portfolio for such options is, as discussed above, limited
to 5% of the Portfolio's net assets, and the Portfolio will have no liability
in connection with such options beyond payment of the option premium and
related commissions.     
   
OTHER DERIVATIVE TRANSACTIONS     
   
  The International Balanced, International Equity Index, Strategic Bond, and
High Yield Bond Portfolios may engage in swap transactions, specifically
interest rate, currency and index swaps and in the purchase or sale of related
caps, floors and collars. The Emerging Markets Equity Portfolio may also
engage in those transactions and, in addition, may engage in equity swap
transactions. In a typical interest rate swap agreement, one party agrees to
make payments equal to a floating interest rate on a specified amount (the
"notional amount") in return for payments equal to a fixed interest rate on
the same amount for a specified period. If a swap agreement provides for
payments in different currencies, the parties might agree to exchange the
notional amount as well. The purchaser of an interest rate cap or floor, upon
payment of a fee, has the right to receive payments (and the seller of the cap
is obligated to make payments) to the extent a specified interest rate exceeds
(in the case of a cap) or is less than (in the case of a floor) a specified
level over a specified period of time or at specified dates. The purchaser of
an interest rate collar, upon payment of a fee, has the right to receive
payments (and the seller of the collar is obligated to make payments) to the
extent that a specified interest rate falls outside an agreed upon range over
a specified period of time or at specified dates.     
   
  Currency, index and equity swaps, caps, floors, and collars are similar to
those described in the preceding paragraph, except that, rather than being
determined by variations in specified interest rates, the obligations of the
parties are determined by variations in specified currency interest rate or
equity indexes.     
   
  The amount of a Portfolio's potential gain or loss on any swap transaction
is not subject to any fixed limit. Nor is there any fixed limit on the
Portfolio's potential loss if it sells a cap, floor or collar. If a Portfolio
buys a cap, floor or collar, however, the Portfolio's potential loss is
limited to the amount of the fee that it has paid. Swaps, caps, floors and
collars tend to be more volatile than many other types of investments.
Nevertheless, a Portfolio will use these techniques only as a risk management
tool and not for purposes of leveraging the     
 
                                      49
<PAGE>
 
   
Portfolio's market exposure or its exposure to changing interest rates,
security values or currency values. Rather, a portfolio will use these
transactions only to preserve a return or spread on a particular investment or
portion of its investments, to protect against currency fluctuations, as a
duration management technique, to protect against any increase in the price of
securities the Portfolio anticipates purchasing at a later date, or to gain
exposure to certain markets in the most economical way possible. Nor will a
Portfolio sell interest rate caps, floors or collars if it does not own
securities providing the interest that the Portfolio may be required to pay.
       
  The use of swaps, caps, floors and collars involves investment techniques
and risks different from those associated with other portfolio security
transactions. If the sub-investment manager is incorrect in its forecasts of
market values, interest rates, currency rates and other applicable factors,
the investment performance of a Portfolio will be less favorable than if these
techniques had not been used. These instruments are typically not traded on
exchanges. Accordingly, there is a risk that the other party to certain of
these instruments will not perform its obligations to the Fund or that a
Portfolio may be unable to enter into offsetting positions to terminate its
exposure or liquidate its investment under certain of these instruments when
it wishes to do so. Such occurrences could result in losses to the Portfolio.
The sub-investment manager, however, will consider such risks and will enter
into swap, cap, floor, and collar transactions only when it believes that the
risks are not unreasonable.     
 
FOREIGN CURRENCY MANAGEMENT STRATEGIES
   
  The extent to which the several Portfolios may invest in foreign securities
is summarized above under "Risk Factors--Risks of Foreign Securities." Ways in
which some of these Portfolios may use forward currency contracts, and some
may use currency option contracts, to manage their currency exposure are
discussed in the paragraphs that follow. Certain Portfolios also may use
currency futures contracts and options thereon for these purposes, as
discussed above under "Financial Futures Contracts" and "Options on Futures
Contracts and Stock Indexes." In addition to the Portfolios listed there, the
Mid Cap Growth, Special Opportunities, Small Cap Growth, Global Equity,
International Balanced, International Equity Index, Short-Term U.S.
Government, and Strategic Bond Portfolios may use those same currency
management techniques. Finally, currency swaps, caps, floors or collars may
also be used for these purposes by the Global Equity, International Balanced,
International Equity Index, Emerging Markets Equity, Strategic Bond, and High
Yield Bond Portfolios to the extent discussed above under "Other Derivative
Transactions" (although the Global Equity Portfolio will not use these
techniques for the other purposes described there).     
   
  Transaction Hedging. When any Portfolio enters into a contract for purchase
or sale of a security denominated in a foreign currency, it may be required to
settle a purchase transaction in the relevant foreign currency or receive the
proceeds of a sale in that currency. In either event, the Fund may be obliged
to acquire or dispose of such foreign currency as is presented by the
transaction by selling or buying an equivalent amount of United States
dollars. Furthermore, the Portfolio may wish to "lock in" the United States
dollar value of the transaction at or near the time of a purchase or sale of
securities at the exchange rate or rates then prevailing between the United
States dollar and the currency in which the foreign security is denominated.
Therefore, certain of the Portfolios may, for a fixed amount of United States
dollars, enter into a forward foreign exchange contract to implement a
strategy known as "transaction hedging." The Portfolios that may enter into
forward exchange contracts are the Large Cap Value, Mid Cap Value, Mid Cap
Growth, Special Opportunities, Small Cap Value, Small Cap Growth, Global
Equity, International Balanced, International Equity Index, International
Equities, International Opportunities, Emerging Markets Equity, Short-Term
U.S. Government, Strategic Bond, and High Yield Bond Portfolios.     
 
                                      50
<PAGE>
 
  To effect the translation of the amount of foreign currencies involved in
the purchase and sale of foreign securities and to effect the "transaction
hedging" described above, the Portfolio may purchase or sell such foreign
currencies on a "spot" (i.e. cash) basis. Alternatively, the Portfolios listed
in the preceding paragraph may enter into forward exchange purchase or sale
contracts, whereby the Portfolio purchases or sells a specific amount of
foreign currency, at a price set at the time of the contract, for receipt or
delivery at a specified date which may be any fixed number of days in the
future. Such spot and forward foreign exchange transactions may also be
utilized to reduce the risk inherent in fluctuations in the exchange rate
between the United States dollar and the relevant foreign currency when
foreign securities are purchased or sold for settlement beyond customary
settlement time. Neither type of foreign currency transaction will eliminate
fluctuations in the prices of the Portfolio's securities or prevent loss if
the price of such securities should decline.
   
  Portfolio Hedging. Some portion of those Portfolios that can invest in
foreign securities will be denominated or quoted in foreign currencies. As a
result, the value of each Portfolio in United States dollars is subject to
fluctuations in the exchange rate between such foreign currencies and the
United States dollar. When, in the opinion of the sub-investment managers, it
is desirable to limit or reduce exposure in a foreign currency in order to
moderate potential changes in the United States dollar value of the Portfolio,
certain of the Portfolios may enter into a forward foreign currency exchange
contract by which the United States dollar value of all or part of the
underlying foreign portfolio securities can be approximately matched by an
equivalent United States dollar liability. This technique is known as
"portfolio hedging" and moderates or reduces the risk of change in the United
States dollar value of the Portfolio's securities only during the period
before the maturity of the forward contract (which will not be in excess of
one year). The Portfolios that can engage in this technique are those listed
above that are authorized to enter engage in "Transaction Hedging". Hedging
against a decline in the value of currency does not eliminate fluctuations in
the prices of the Portfolio's securities or prevent losses if the prices of
such securities decline.     
   
  Proxy Currencies. In implementing the above-described currency hedging
techniques, the Mid Cap Growth, Global Equity, International Balanced, and
International Equity Index Portfolios may use a forward contract on a "proxy"
currency, instead of the currency being hedged. A proxy currency is one that
the sub-investment manager believes will bear a close relationship to the
currency being hedged and believes will at least equal the performance of such
currency relative to the U.S. dollar.     
   
  Other Techniques for Managing Currency Exposure. The Mid Cap Growth, Global
Equity, International Balanced, International Equity Index, International
Opportunities, Emerging Markets Equity, and Strategic Bond Portfolios may use
additional techniques when the sub-investment manager for one of these
Portfolios believes that the currency of a particular country may suffer a
significant decline against the U.S. dollar or against another currency. In
that case, the Portfolio may enter into a currency contract to sell, for a
fixed amount of U.S. dollars or other appropriate currency, the amount of
foreign currency approximating the value of some or all of the Portfolio's
securities denominated in such foreign currency. The currency contract may
call for the Portfolio to receive a currency other than U.S. dollars, for
example, if such other currency is believed to be undervalued or necessary to
bring the Portfolio's overall exposure to various currencies into a more
desirable balance. For similar purposes, International Balanced, International
Opportunities, and Strategic Bond Portfolios may also enter into contracts to
purchase, for a fixed amount of U.S. dollars, or other appropriate currency,
an amount of foreign currency corresponding to the value of some of the
Portfolio's securities.     
   
  If a Portfolio is to receive a currency other than U.S. dollars pursuant to
a forward currency sales contract, or if the Portfolio enters into a forward
currency purchase contract, a risk exists that the value of the currency to
    
                                      51
<PAGE>
 
be received by the Portfolio could vary differently in relation to the U.S.
dollar than does the currency in which the related securities are denominated.
This could result in gains or losses to the Portfolio.
   
  Options on Currencies. The Mid Cap Growth, Global Equity, International
Balanced, International Equity Index, International Opportunities, Emerging
Markets Equity, Strategic Bond, and High Yield Bond Portfolios may also
purchase and write put and call options on foreign currencies (traded on U.S.
and foreign exchanges or over-the-counter markets) to manage the Portfolios'
exposure to changes in currency exchange rates. Call options on foreign
currencies written by a Portfolio will be "covered," which means that the
Portfolio will own at all times an equal amount of, or an offsetting position
in, the underlying foreign currency. With respect to put options on foreign
currencies written by a Portfolio, the Portfolio will establish a segregated
account with its custodian bank consisting of cash, U.S. Government securities
or other high grade liquid debt securities in an amount equal at all times to
the amount the Portfolio would be required to deliver upon exercise of the
put. The characteristics and risks of these currency option transactions are
similar to those with respect to put and call options on securities. See
"Writing Exchange-Traded Covered Call Options," "Purchasing Exchange-Traded
Protective Put Options," "Risks of Options and Futures Transactions," and "Use
of Options and Futures by the Mid Cap Growth, Special Opportunities, Small/Mid
Cap CORE Equity, Small Cap Growth, Global Equity, International Balanced,
International Equity Index, Emerging Markets Equity, Short-Term U.S.
Government, Sovereign Bond, Strategic Bond, and High Yield Bond Portfolios"
above.     
 
RULE 144A SECURITIES
   
  All Portfolios, other than the Growth & Income, Large Cap Growth and Real
Estate Equity Portfolio, may purchase unregistered securities that are
eligible for resale to "qualified institutional buyers" pursuant to Rule 144A
under the Securities Act of 1933. The Trustees have directed the sub-
investment manager of each of the eligible Portfolios to determine on a case-
by-case basis whether each issue of Rule 144A securities owned by the
Portfolio is an illiquid security. If illiquid, a Rule 144A security may not
be purchased by the Money Market Portfolio, but may be purchased by any other
eligible Portfolio, subject to such Portfolio's limit on the amount of its
assets that can be invested in any illiquid securities (10% in the case of the
Special Opportunities, International Equities, and Short-Term U.S. Government,
and 15% as to all other eligible Portfolios). Purchasing this type of
unregistered security could have the effect of increasing the level of
illiquidity and volatility in the Portfolio.     
 
WHEN ISSUED SECURITIES AND FORWARD COMMITMENTS
   
  The Equity Index, Large Cap Value, Mid Cap Value, Mid Cap Growth, Special
Opportunities, Small/Mid Cap CORE Equity, Small Cap Value, Small Cap Growth,
Global Equity, International Balanced, International Equity Index,
International Equities, International Opportunities, Emerging Markets Equity,
Short-Term U.S. Government, Diversified Bond Index, Sovereign Bond, Strategic
Bond, and High Yield Bond Portfolios may purchase securities on a when-issued
or delayed delivery basis. When such transactions are negotiated, the price of
such securities is fixed at the time of commitment, but delivery and payment
for the securities may take place a month or more after the date of the
commitment to purchase. The securities so purchased are subject to market
fluctuations, and no interest rate accrues to the purchaser during this
period.     
 
  In addition, these Portfolios may make contracts to purchase securities for
a fixed price at a future date beyond customary settlement time ("forward
commitments") because new issues of securities are typically offered to
investors on that basis. Forward commitments involve a risk of loss if the
value of the security to be purchased declines prior to the settlement date.
This risk is in addition to the risk of decline in value of the
 
                                      52
<PAGE>
 
Portfolio's other assets. Although the Portfolio will enter into such
contracts with the intention of acquiring the securities, the Portfolio may
dispose of a commitment prior to settlement if the sub-investment managers
deem it appropriate to do so. The Portfolio may realize short-term profits or
losses upon the sale of forward commitments.
 
  Each Portfolio will maintain in a segregated account with its custodian cash
or liquid high grade debt securities that at all times equal the amount of its
when-issued and forward commitments.
 
PORTFOLIO LENDING
   
  The Equity Index, Large Cap Value, Mid Cap Value, Mid Cap Growth, Special
Opportunities, Small/Mid Cap CORE Equity, Small Cap Value, Small Cap Growth,
Global Equity, International Balanced, International Equity Index,
International Opportunities, Emerging Markets Equity, Short-Term U.S.
Government, Diversified Bond Index, Strategic Bond, and High Yield Bond
Portfolios may lend portfolio securities to brokers, dealers, and financial
institutions if the loan is collateralized in accordance with applicable
regulatory requirements. When lending portfolio securities, there is a risk
that the borrower may fail to return the securities involved in the
transactions, in which case the Portfolio may incur a loss. It is a
fundamental restriction of the Portfolio not to lend portfolio securities
having a total value in excess of 33 1/3% of the total assets of the Portfolio
from which the securities have been lent.     
 
THE S&P 500
 
  The Equity Index Portfolio seeks to provide investment results that
correspond to the total return of the U.S. market as represented by the S&P
500. The S&P 500 is an index that is constructed by the Standard & Poor's
Corporation ("Standard & Poor's" or "S&P"), which chooses stocks on the basis
of market values and industry diversification. Most of the largest 500
companies listed on the U.S. stock exchanges are included in the index.
Additional stocks that are not among the 500 largest stocks, by market value,
are included in the S&P 500 for diversification purposes. The index is
capitalization weighted--that is, stocks with a larger capitalization (shares
outstanding times current price) have a greater weight in the index. Selection
of a stock for inclusion in the S&P 500 Index in no way implies an opinion by
S&P as to its attractiveness as an investment.
 
  The Fund and the insurance products supported by the Fund are not sponsored,
endorsed, sold or promoted by Standard & Poor's. Standard & Poor's makes no
representation or warranty, express or implied, to the owners of the insurance
products supported by the Fund or any member of the public regarding the

THE LEHMAN BROTHERS GOVERNMENT/CORPORATE AND AGGREGATE BOND INDEXES     
   
  The Lehman Brothers Government/Corporate Index (the "Government/Corporate
Index") is intended to measure the performance of the domestic, fixed-rate
investment grade debt market. The Government/Corporate Index is composed of
(1) all public obligations of the U.S. Government, its agencies and
instrumentalities (excluding "flower" bonds and pass-through issues such as
GNMA certificates) and (2) all publicly issued, fixed-rate nonconvertible,
investment grade, dollar-denominated, SEC-registered obligations of domestic
corporations, foreign governments and supranational organizations.     
   
  The Lehman Brothers Aggregate Bond Index (the "Aggregate Bond Index") covers
the U.S. investment grade fixed-rate bond market, including government and
corporate securities, agency mortgage pass-through securities, and asset-
backed securities. The Aggregate Bond Index covers those securities in the
Government/Corporate Bond Index, plus those covered by the Lehman Mortgage-
Backed Securities Index ("MBS Index") and the Lehman Asset-Backed Securities
Index ("ABS Index"). The MBS Index covers all fixed-rate securities backed by
mortgage pools of the Government National Mortgage Association ("GNMA"),
Freddie Mac and Fannie Mae. The ABS Index covers several subsectors--including
credit and charge cards, auto, utilities and home equity loans--and includes
pass-through, bullet, and controlled amortization structures.     
   
  All non-U.S. Government issues in the Government/Corporate Index and the
Aggregate Bond Index are rated at least Baa by Moody's Investors Service, Inc.
("Moody's") or, if unrated by Moody's, BBB by Standard & Poor's Ratings Group
("Standard & Poor's").     
   
  Lehman Brothers, Inc. is neither a sponsor of nor in any other way
affiliated with the Portfolio or the insurance products supported by the
Portfolio. Inclusion of a security in the Government/Corporate or Aggregate
Bond Indexes in no way implies an opinion of Lehman Brothers, Inc. as to its
attractiveness or appropriateness as an investment. The Portfolio and the

THE MSCI EAFE GDP INDEX     
   
  The International Equity Index Portfolio seeks to provide investment results
that correspond to the total return of the MSCI EAFE GDP Index. The MSCI EAFE
GDP Index weights countries such that a country with a larger GDP will have a
greater weight in the index. Stocks within those countries are capitalization
weighted; that is stocks with a larger capitalization have a greater weight in
the index.

INVESTMENT COMPANIES     
   
  Each Portfolio may invest up to 10% of its total assets in shares of other
investment companies investing exclusively in securities in which it may
otherwise invest. Because of restrictions on direct investment by U.S.
entities in certain countries, other investment companies may provide the most
practical or only way for a     
 
                                      55
<PAGE>
 
   
Portfolio to invest in certain markets. Such investments may involve the
payment of substantial premiums above the net asset value of those investment
companies' portfolio securities and are subject to limitations under the
Investment Company Act. A Portfolio also may incur tax liability to the extent
it invests in the stock of a foreign issuer that is a "passive foreign
investment company" regardless of whether such "passive foreign investment
company" makes distributions to the Portfolio. the Portfolios do not intend to
invest in other investment companies unless the potential benefits are judged
to exceed the associated costs. As a shareholder in an investment company, a
Portfolio would bear its ratable share of that investment company's expenses,
including advisory and administration fees. The Emerging Markets Equity
Portfolio is the most likely to invest in other investment companies; and John
Hancock and the sub-investment manager have agreed to waive their own
management fees with respect to the portion of that Portfolio's assets
invested in other open-end (but not closed-end) investment companies.     
 
                            MANAGEMENT OF THE FUND
 
  The Board of Trustees of the Fund is responsible for the administration of
the affairs of the Fund. The Board may exercise all powers of the Fund except
those powers which are conferred upon or reserved to the shareholders.
   
  John Hancock serves as the Fund's investment manager. Total assets under
management by John Hancock and its subsidiaries as of December 31, 1997,
amounted to over $    billion, of which over $   billion was owned by John
Hancock. John Hancock's offices are located at John Hancock Place, Boston,
Massachusetts 02117.     
   
  Pursuant to five Investment Management Agreements (two dated as of April 12,
1988, one dated April 15, 1994, one dated February 14, 1996, and one dated
        , 1998), as amended, John Hancock, a registered investment adviser
under the Investment Advisers Act of 1940, advises the Fund in connection with
policy decisions; provides administration of day-to-day operations; serves as
the Fund's transfer agent and dividend disbursing agent; provides personnel,
office space, equipment, and supplies for the Fund; maintains records required
by the Investment Company Act of 1940 computes income and yield of each
Portfolio; and supervises activities of the sub-investment managers referred
to below and of other service providers to the Fund.

MONEY MARKET PORTFOLIO     
   
  John Hancock has day-to-day responsibility for making investment decisions
and placing investment orders for the Money Market Portfolio.     
 
                               ----------------
 
  John Hancock pays the fees of each of the sub-investment managers pursuant
to the agreements with each and Advisers likewise pays the fee of
International Advisers. Therefore, the sub-investment management arrangements
result in no additional charge to the Fund or to the contractholders. (Further
discussion of the Fund's management is included in the Statement of Additional
Information under "Board of Trustees and Officers of the Fund.")
   
  John Hancock also performs investment advisory services for a number of
other accounts and clients, none of which is given preference over the Fund in
allocating investment opportunities. When opportunities occur which are
consistent with the investment objective of more than one account, it is the
policy of each not to favor any one account over another, and investment
opportunities are allocated in a manner deemed equitable to the particular
accounts involved based on such factors as their respective investment
objectives and then current investment and cash positions. Subject to these
requirements, Fund orders may be combined with orders of other accounts or
clients advised by John Hancock or any of the sub-investment managers at
prices which are averaged.     
 
  Under the Investment Management Agreements, as amended, John Hancock
provides the Fund with office space, supplies and other facilities required
for the business of the Fund. It pays the compensation of Fund officers and
employees and the expenses of clerical services relating to the administration
of the Fund. Expenses not expressly assumed by John Hancock under the
Investment Advisory Agreement are paid by the Fund. These include, but are not
limited to, taxes, custodian and auditing fees, brokerage commissions,
advisory fees, compensation of unaffiliated trustees, the Fund's fidelity bond
coverage, printing and distributing to
 
                                      63
<PAGE>
 
   
contractholders of annual and semi-annual reports and voting materials,
tabulating votes,compensation for certain accounting, valuation, and
compliance services, legal expenses, registration costs, proxy costs,
organizational costs, association dues, and other expenses related to the
Fund's operations. (A further discussion of the Fund expenses is included in
the Statement of Additional Information under "Investment Management and
Operating Expenses" and "Portfolio Transactions and Brokerage Allocation.")
       
  Registered broker/dealers affiliated with any one of the sub-investment
managers may be used to execute a transaction on behalf of the Portfolios but
only if the price and execution is as favorable as that which would be
available from an unaffiliated broker/dealer and no less favorable than the
affiliated broker/dealer's contemporaneous charges to its other most favored,
but unaffiliated, customers. During 1997, the International Opportunities
Portfolio paid commissions of $    and $    to Robert Fleming Securities
Limited ("Robert Fleming") and Jardine Fleming & Co. ("JFC"), respectively,
which represented approximately 5% and 1.6%, respectively, of total
commissions paid during 1996 by the International Opportunities Portfolio. For
that Portfolio, transactions effected through Robert Fleming and JFC
represented   % and   % of the aggregate dollar amount of transactions
involving payment of commissions. Robert Fleming and JFC are affiliates of
Rowe Price-Fleming, sub-investment manager of the International Opportunities
Portfolio. Also during 1997, Neuberger & Berman, a registered broker-dealer
that also serves as sub-investment manager of the Mid Cap Value Portfolio,
executed transactions representing approximately   % of the aggregate dollar
amount of transactions for that Portfolio involving the payment of
commissions. Commissions for the transactions executed by Neuberger & Berman
totaled approximately $   , which represented just under   % of all
commissions paid by that Portfolio during 1997. Finally, also during 1997, the
Small Cap Growth and Special Opportunities Portfolios paid commissions of $
and $  , respectively, to J.P. Morgan Securities, Inc. ("J.P. Morgan
Securities"), which represented approximately   % and   %, respectively, of
total commissions paid during 1997 by each Portfolio. For each of these
Portfolios, transactions effected through J.P. Morgan Securities represented
  % and   %, respectively, of the aggregate dollar amount of transactions
involving payment of commissions. J.P. Morgan Securities is an affiliate of
J.P. Morgan, sub-investment manager of the Strategic Bond Portfolio. The Fund
may not engage in any transactions in which John Hancock, any of the sub-
investment managers, or any of their affiliates acts as principal.     
 
                         SHARES, TAXES, AND DIVIDENDS
 
  The Fund issues a separate series of shares of beneficial interest for each
Portfolio. Each share issued with respect to a Portfolio has a pro rata
interest in the net assets of that Portfolio. Each share is entitled to one
vote on matters submitted to a vote of shareholders of the Fund. The votes of
all classes are cast on an aggregate basis, except that if the interests of
the Portfolios differ, voting is on a Portfolio-by-Portfolio basis. In the
latter case, approval or disapproval by the shareholders in one Portfolio
would not generally be a prerequisite of approval or disapproval by
shareholders in another Portfolio. All shares may be redeemed at any time. The
assets of each Portfolio are charged with the liabilities of that Portfolio
and a proportionate share of the general liabilities of the Fund. Because John
Hancock Variable Annuity Accounts U, V, and I; John Hancock Variable Life
Accounts U, V, and S; and John Hancock Mutual Variable Life Insurance Account
UV currently hold all of Fund's shares, those Separate Accounts may be deemed
to control the Fund.
 
  The Fund intends to qualify as a regulated investment company under
Subchapter M of the Internal Revenue Code ("Code"). It is the Fund's policy to
comply with the provisions of the Code regarding distribution of investment
income and capital gains so that the Fund will not be subject to Federal
income tax on amounts distributed. The Fund expects to distribute to the
Separate Accounts owning its shares all or substantially all net investment
income and net realized capital gains, if any, from the sale of investments.
 
                                      64
<PAGE>
 
  A dividend from the net investment income of the Money Market Portfolio will
be declared and distributed daily. Dividends from net investment income of the
other Portfolios, except for the Special Opportunities Portfolio, will be
declared and distributed monthly. Dividends, if any, from net investment
income of the Special Opportunities Portfolio will be declared and distributed
annually. The Fund will distribute all of its net realized capital gains
annually. Dividends and capital gains distributions will normally be
reinvested in additional full or fractional shares of the Portfolio to which
they relate and will be appropriately credited to investment performance under
John Hancock and JHVLICO variable life insurance and annuity contracts. (A
more complete discussion of taxes and dividends is included in the Statement
of Additional Information under "Redemption and Pricing of Shares" and
"Taxes.")
 
  It is the policy of each of the Portfolios to comply with certain investment
diversification requirements set forth in Treasury Department regulations. A
variable life insurance policy or annuity contract investing in a Portfolio
that failed to meet these diversification requirements would, unless and until
the failure can be corrected in a procedure afforded by the Internal Revenue
Service, subject contractholders to taxation of income in the contract or
policy for that or any subsequent period. For a discussion of the tax
implications of owning a variable annuity contract or a variable life
insurance policy for which the Fund serves as the investment medium, please
refer to the Prospectus for such contract or policy attached at the front of
this Prospectus.
 
  Those Portfolios that invest substantial amounts of their assets in foreign
securities may make an election to pass through John Hancock or JHVLICO any
taxes withheld by foreign taxing jurisdictions on foreign source income. Such
an election will result in additional taxable income and income tax to John
Hancock. The amount of additional income tax, however, may be more than offset
by credits for the foreign taxes withheld, which are also passed through.
These credits may provide a benefit to John Hancock or JHVLICO.
 
                       PURCHASE AND REDEMPTION OF SHARES
 
  Shares of beneficial interest of each Portfolio of the Fund are offered only
to the corresponding subaccount of a Separate Account to which premiums have
been allocated by the owner of an insurance policy or an annuity contract.
Shares are sold at their net asset value as next determined after receipt of a
net premium by the Separate Account, without the addition of any selling
commission or sales load.
 
  Shares are redeemed at their net asset value as next determined after
receipt of a surrender request by the Separate Account. No fee is charged on
redemption. Redemption payments will usually be paid within seven days after
receipt of the redemption request, except that the right of redemption may be
suspended or payments postponed whenever permitted by applicable law and
regulations. Fund shares are also purchased and redeemed as a result of
transfer requests, loans, loan repayments, and similar Separate Account
transactions, in each case without any sales load or commission and at the net
asset value per share computed for the day as of which such Separate Account
transactions are effected. (Further discussion of the purchase and redemption
of shares is included in the Statement of Additional Information under
"Redemption and Pricing of Shares.")
 
                                NET ASSET VALUE
 
  The net asset value per share of each Portfolio is determined once daily,
after the declaration of dividends, if any, as of 4:00 p.m., New York City
time, on each business day the New York Stock Exchange ("Exchange") is open
for unrestricted trading.
 
                                      65
<PAGE>
 
  The net asset value per share of each Portfolio is determined by adding the
value of all portfolio securities and other assets, deducting all portfolio
liabilities, and dividing by the number of outstanding shares. All Fund
expenses will be accrued daily for this purpose.
 
  Securities and covered call and put options that are listed on a stock
exchange are normally valued at the closing sales price. If there were no
sales during the day, they are normally valued at the last previous sale or
bid price reported, as are equity securities that are traded in the over-the-
counter market.
 
  Non-exchange traded debt securities (other than certain short-term
investments) are valued on the basis of valuations furnished by a pricing
service which uses electronic data processing techniques, without exclusive
reliance upon quoted prices. Short-term investments with a remaining maturity
of 60 days or less, and all investments of the Money Market Portfolio, are
valued at amortized cost which approximates market value. The amortized cost
method involves valuing a security at its cost on the date of purchase and
thereafter assuming a constant amortization to maturity of the difference
between the principal amount due at maturity and the cost of the security to
the Portfolio.
 
  Any other security for which market quotations are not readily available and
any other property for which valuation is not otherwise available is valued at
fair value as determined in good faith by, or under the direction of, the
Board of Trustees.
 
  Financial futures contracts, options thereon and options on stock indexes
are valued at the last trade price of the day. In the absence of a trade on a
given day, the value is used which is established by the exchange on which the
instrument is traded.
 
  Trading in the Portfolios that may purchase securities on European and Far
Eastern securities exchanges and over-the-counter markets is normally
completed at various times before the close of business on each day on which
the New York Stock Exchange is open. The values of such securities used in
computing net asset value per share are determined as of such times. Trading
of these securities may not take place on every New York Stock Exchange
business day and may take place on days which are not business days in New
York. With the exception of certain holidays, the Fund calculates net asset
value per share as of the close of regular trading on the New York Stock
Exchange on each day on which that Exchange is open. Therefore, such
calculation does not take place contemporaneously with the determination of
the prices of many of the International and Special Opportunities Portfolios'
securities used in such calculation. If events materially affecting the value
of such securities occur between the time when their price is determined and
the time when net asset value is calculated, such securities will be valued at
fair value as determined by or under the direction of the Board of Trustees in
good faith.
 
                            INVESTMENT PERFORMANCE
 
  From time to time, the Portfolios may advertise certain investment
performance figures. THESE FIGURES ARE BASED ON HISTORICAL EARNINGS AND ARE
NOT INTENDED TO INDICATE FUTURE PERFORMANCE.
 
  The Money Market Portfolio may advertise its current yield and its effective
yield. The current yield of the Money Market Portfolio refers to the income
earned by the Portfolio during a seven-day period which is specified in the
advertisement. The income earned during that week is then assumed to be earned
each week for 52 weeks. The effective yield is calculated similarly, but the
income earned by an investment in the Portfolio is assumed to be reinvested
daily.
 
                                      66
<PAGE>
 
  The other Portfolios may also advertise yield. The yield for each of these
Portfolios refers to the net investment income earned by the Portfolio during
a 30-day period which is specified in the advertisement. The income earned
during this period is then assumed to be earned for a full year and to be
reinvested each month for six months. The resulting semi-annual yield is
doubled.
 
  Each of the Portfolios may advertise its average annual total return. In
general, total return is based upon the overall dollar or percentage change in
the value of a hypothetical investment in a Portfolio over a period of time
(which is specified in the advertisement), assuming all distributions are
reinvested. Average annual total return reflects the hypothetical annually
compounded return that would have produced the same cumulative rate of return
if the Portfolio's performance had been constant over the entire period.
Average annual returns tend to smooth out variations in a Portfolio's return;
they are not the same as actual year-by-year results.
 
  Yields and total returns advertised for the Portfolios include the effect of
deducting each Portfolio's expenses, but may not include charges and expenses
attributable to any particular insurance product. Because shares of the
Portfolios can only be purchased through a variable annuity contract or
variable life insurance policy, a prospective contractholder should carefully
review the separate account prospectus attached at the front of this
prospectus for information on relevant charges and expenses. For more
information about performance advertising, see "Calculation of Performance
Data" in the Statement of Additional Information to this prospectus.
 
  Additional performance information is also included in the Fund's Annual
Report to contractholders which will be made available upon request and
without charge.
 
    CHANGES IN INTERNATIONAL EQUITIES PORTFOLIO'S INVESTMENT OBJECTIVE AND
                                   POLICIES
 
  The current investment objective and policies of the International Equities
Portfolio (formerly, International Portfolio) were approved by vote of that
Portfolio's shareholders, effective May 1, 1994, and that Portfolio's name was
changed from "Global Portfolio" to "International Portfolio." The principal
changes were to eliminate investments in debt securities (other than for
defensive purposes) as one of the Portfolio's principal investment strategies;
to add a policy that at least 80% of the Portfolio's total assets be invested
in equity securities; to increase from two to three the minimum number of
countries other than the United States in which the Portfolio generally will
invest; and to add a new policy that the Portfolio will invest primarily in
foreign (non-United States) securities.

                        APPENDIX A--PERFORMANCE FIGURES
   
  This Appendix includes historical total return information for each of the
Portfolios, that existed at December 31, 1997, other than the Money Market
Portfolio. This information represents past performance and assumes
reinvestment of all distributions. For information as to how this information
was computed for such existing Portfolios, see "Investment Performance" and
"Changes in International Equities Portfolio's Investment Objectives and
Policies" in this Prospectus and "Calculation of Performance Data" in the
Fund's Statement of Additional Information.     
   
  Certain Portfolios have been offered only commencing in May, 1996: Equity
Index, Large Cap Value, Mid Cap Growth, Mid Cap Value, Small Cap Growth, Small
Cap Value, Strategic Bond, International Opportunities, and International
Balanced. Certain other Portfolios have been offered only commencing in May
1998: Small/Mid Cap CORE Equity, Global Equity, International Equity Index,
Emerging Market Equity, Diversified Bond Index, and High Yield Bond
Portfolios. Since the Portfolios that commenced in May 1996 have only limited
performance history, and since the Portfolios that commenced in May 1998 do
not have any performance history, this Appendix also includes total return
information for certain similar accounts that are managed by these Portfolios'
respective sub-investment managers. In each case the Portfolio's actual or
estimated expenses (after reimbursement) as set forth in this Prospectus under
"Synopsis of Expense Information" have been substituted for the actual fees
and expenses (other than brokerage, interest, and other such portfolio
transaction expenses) of the accounts for which performance figures are shown.
Also, except as otherwise noted, the accounts for which performance figures
are shown include all of the investment company and other accounts of the
appropriate sub-investment manager or management team that (a) have been
managed with investment objectives, policies, and strategies substantially
similar to those used in managing the Portfolio and (b) are of sufficient size
that their performance would be considered relevant to the owner of a policy
or contract investing in that Portfolio.     
 
  THE PERFORMANCE FIGURES SET FORTH ON THE FOLLOWING PAGES DO NOT REFLECT THE
DEDUCTION OF SALES, TAX, RISK, ADMINISTRATIVE, MORTALITY, OR OTHER CHARGES
UNDER THE TERMS OF THE VARIABLE ANNUITY CONTRACTS AND VARIABLE LIFE INSURANCE
POLICIES THAT MAY INVEST IN THE FUND. THESE CHARGES MAY BE SUBSTANTIAL AND
WILL CAUSE THE INVESTMENT RETURN UNDER SUCH A CONTRACT OR POLICY TO BE LESS
THAN THAT OF THE PORTFOLIOS SELECTED BY THE CONTRACTOWNER. YOU SHOULD REVIEW
THE SEPARATE ACCOUNT PROSPECTUS ATTACHED AT THE FRONT OF THIS PROSPECTUS FOR
DETAILED INFORMATION ABOUT SUCH CHARGES.
 
  The information set forth in this Appendix should not be interpreted as
indicative of future performance of any Portfolio.

1. The Strategic Bond Composite represents the performance of all accounts 
   included in two composites, as follows:
   a) a 75% allocation to the Public Only Active Fixed Income Composite.
   b) a 25% allocation to the Non-US Hedged Fixed Income Composite.
   c) Each of these is an asset-weighted composite representing all accounts
      with assets of at least $1 million managed using a substantially similar
      investment strategy.
2. The Strategic Bond Benchmark represents the following weighting of two 
   indices:
   a) a 75% allocation to the Lehman Brothers Aggregate Bond Index, composed of
      securities from the Lehman Brothers Government/Corporate Bond Index, the
      Mortgage-Backed Securities Index and the Asset-Backed Securities Index.
      Total return comprises price appreciation/depreciation and income as a
      percentage of the original investment. Indexes are rebalanced monthly by
      market capitalization. It is a capitalization-weighted index calculated on
      a total return basis with income reinvested.
   b) a 25% allocation to the JP Morgan Non-US Government Bond Index, Hedged,
      which is a total return, market capitalization weighted index, rebalanced
      monthly consisting of the following countries: Australia, Belgium, Canada,
      Denmark, France, Germany, Italy, Japan, Netherlands, Spain, Sweden, and
      United Kingdom. This index is hedged into US dollars using a rolling 1-
      month forward exchange contract as the hedging instrument. It is a
      capitalization-weighted index calculated on a total return basis with
      income reinvested.
3. The performance results are net of Fund asset management expenses and are
   total returns, which assume the reinvestment of dividends and interest. The
   total return figure reflects the expense reimbursements and capital
   contribution described in the footnotes to the "Financial Highlights" in this
   Prospectus.

                               BUSINESS HISTORY
   
  John Hancock Variable Series Trust I, (the "Fund") is an open-end management
investment company which was incorporated on September 23, 1985, under the
laws of the State of Maryland and was reorganized as a Massachusetts business
trust, effective April 29, 1988. See the heading "The Trust's Organization and
Shares" below. The Fund has twenty-four separate Portfolios, each with a
separate series of shares. Shares of the Fund are currently sold to John
Hancock Variable Life Accounts U, V, and S to fund variable life insurance
policies issued by John Hancock Variable Life Insurance Company ("JHVLICO");
John Hancock Variable Annuity Accounts U and V, to fund variable annuity
contracts issued by John Hancock Mutual Life Insurance Company ("John
Hancock"); John Hancock Variable Annuity Account I, to fund variable annuity
contracts issued by JHVLICO and John Hancock Mutual Variable Life Insurance
Account UV to fund variable life insurance policies issued by John Hancock. It
is anticipated that, in the future, Fund shares may be sold to other separate
investment accounts of JHVLICO and John Hancock. Each of these separate
accounts is hereinafter referred to as a "Separate Account."     
 
  The Fund is, in part, a successor to three separate investment accounts of
JHVLICO as well as the six separate accounts of John Hancock described below.
On March 28, 1986, all of the investment assets and related liabilities of the
Variable Life Stock, Bond, and Money Market Accounts were transferred to the
Stock, Bond, and Money Market Portfolios of the Fund, respectively, in
exchange for shares of these Portfolios. These transactions were effected
simultaneously pursuant to an Agreement and Plan of Reorganization dated
November 5, 1985, entered into by JHVLICO, the Variable Life Stock, Bond, and
Money Market Accounts, and the Fund.
 
  On February 20, 1987, all of the investment assets and related liabilities
of six Variable Annuity Stock, Bond and Money Market Accounts were transferred
to the Stock, Bond and Money Market Portfolios of the Fund, respectively, in
exchange for shares of these Portfolios. These transactions were effected
simultaneously pursuant to an Agreement and Plan of Reorganization dated June
10, 1986, entered into by John Hancock, the six Variable Annuity Stock, Bond
and Money Market Accounts, and the Fund.
 
  In 1996, the Stock Portfolio was renamed the Growth & Income Portfolio, and,
in 1995, the Bond Portfolio was renamed the Sovereign Bond Portfolio.
 
                             INVESTMENT TECHNIQUES
 
HEDGING STRATEGIES
   
  Certain hedging strategies are discussed in the Fund's prospectus, under the
heading "Other Hedging Strategies by the Managed, Equity Index, Large Cap
Value, Large Cap Growth, Mid Cap Value, Small Cap Value, and International
Opportunities Portfolios." These strategies are discussed further below. The
Managed, Equity Index, Large Cap Value, Large Cap Growth, Mid Cap Value, Mid
Cap Growth, Special Opportunities, Small/Mid Cap CORE Equity, Small Cap Value,
Small Cap Growth, Global Equity, International Balanced, International Equity
Index, International Opportunities, Emerging Markets Equity, Short-Term U.S.
Government, Strategic Bond, and High Yield Bond Portfolios may engage in
transactions in futures contracts, options on futures contracts, and options
on indexes for hedging purposes. Similarly, the Sovereign Bond Portfolio may
engage in transactions in futures contracts and options thereon for hedging
purposes.     
 
  For example, during a market decline, the selling of the appropriate futures
contract or the purchase of the appropriate put option could enable a
Portfolio to retain securities held in its portfolio, while avoiding part or
all
 
                                       1
<PAGE>
 
of any loss resulting from a decline in their value. Outright sales of such
securities may not be advantageous at that time, for example, because (in the
case of debt instruments) the proceeds would have to be invested in lower-
yielding, shorter-term instruments. Also, with respect to both debt and equity
securities held by a Portfolio, it may be difficult to liquidate positions
quickly when a market decline is anticipated. Similarly, it may be difficult
to re-establish such positions quickly when the decline is over or if the
decline fails to materialize. These difficulties can be reduced by, for
example, selling the appropriate futures contracts when a decline is
anticipated and closing out the futures position when such anticipations
changes.
 
  Similarly, purchasing futures contracts and call options would enable a
Portfolio to take the approximate economic equivalent of a substantial
position in bonds or equity securities more quickly or economically than may
be possible through direct purchases of debt or equity instruments.
 
FURTHER CONSIDERATIONS AS TO OPTIONS AND FUTURES CONTRACTS
 
  Restrictions. A Portfolio will maintain at all times in a segregated account
with its custodian cash or cash equivalents at least equal to the sum of the
purchase prices of all of the Portfolio's open futures purchase positions,
plus the current value of the securities underlying all of the Portfolio's
open futures sales positions that are maintained for non-hedging (speculative)
purposes, plus the exercise price of all outstanding put options on futures
contracts written by the Portfolio, minus the amount of margin deposits with
respect thereto as marked to market each day. Regarding such margin deposits,
see "Margin Requirements for Futures and Options."
 
  Certain Risks. Financial futures, options thereon, and stock index options,
if used by the Fund, will in most cases be based on securities or stock
indexes the components of which are not identical to the portfolio securities
owned or intended to be acquired by a Portfolio and in connection with which
such instruments are used. Furthermore, due to supply and demand imbalances
and other market factors, the price movements of financial futures, options
thereon, and stock index options do not necessarily correspond exactly to the
price movements of the securities, currencies, or stock index on which such
instruments are based. These factors increase the difficulty of implementing a
successful strategy using futures and options contracts.
 
  The Portfolios generally will not take delivery of debt instruments pursuant
to purchasing an interest rate futures contract, nor make a delivery of debt
instruments pursuant to selling an interest rate futures contract. Nor will
the Portfolios necessarily take delivery of or deliver currencies in
connection with currency futures contracts. Instead, a Portfolio may close out
such futures positions by entering into closing futures contract transactions.
Trading in futures or options could be interrupted, for example, because of
supply and demand imbalances arising from a lack of either buyers or sellers.
The futures and options exchanges also may suspend trading after the price has
risen or fallen more than the maximum amount specified by the exchange.
Exercise of options could also be restricted or delayed because of regulatory
restrictions or other factors. Although the sub-investment managers will seek
to avoid situations where these factors would be likely to cause a problem for
the Fund, in some cases they could adversely affect the particular Portfolio's
transactions in these instruments.
 
  Custodial Aspects. In certain circumstances, brokers may have access to
Portfolio assets posted as margin in connection with futures and options
transactions.
 
  In such circumstances, the Fund will use only brokers in whose reliability
and financial soundness it has full confidence, and the Fund will adopt
certain other procedures and limitations to reduce the risk of loss to any
Fund assets which brokers hold or to which they may have access. Nevertheless,
in the event of a broker's insolvency or bankruptcy, it is possible that a
Portfolio may experience a delay or incur costs in recovering such
 
                                       2
<PAGE>
 
assets or might recover less than the full amount due. Also the value of such
assets could decline by the time the Fund could effect such recovery.
 
  If on any day a Portfolio experiences net realized or unrealized gains with
respect to financial futures contracts held through a given broker, it will be
entitled immediately to receive from the broker the net amount of such gains.
The Fund will request payment of such amounts promptly after notification by
the broker that such amounts are due. Thereupon, these assets will be
deposited in the Fund's general or segregated account with the custodian, as
appropriate.
 
SHORT-TERM TRADING
   
  The Large Cap Value, Mid Cap Value, Mid Cap Growth, Special Opportunities,
Small/Mid Cap CORE Equity, Small Cap Value, Small Cap Growth, International
Balanced, International Equity Index, International Opportunities, Diversified
Bond Index, Sovereign Bond, Strategic Bond, and High Yield Bond Portfolios
intend to use short-term trading of securities as a means of managing their
portfolios to achieve their investment objectives. As used herein, "short-term
trading" means the purchase and subsequent sale of a security after it has
been held for a relatively brief period of time, in some instances for less
than three months. A Portfolio may engage in short-term trading in such
instances as the following if the investment manager, or sub-investment
manager, believes the transactions, net of costs (including commissions, if
any), will benefit the Portfolio:     
 
    (a) To avoid potential depreciation in the value of a security held in
  the Portfolio where the Portfolio anticipates that it may decline in market
  value as a result of unfavorable earnings trends and/or an unfavorable
  investment environment.
 
    (b) To increase the return by taking advantage of yield disparities
  between various fixed-income securities in order to realize capital gains
  or improved income on the Portfolio.
 
    (c) To take advantage of movements in the price of a security that the
  sub-investment manager expects to be of relatively short duration.
 
  The investment manager, or sub-investment manager, in reaching a decision to
sell one security and purchase another security at approximately the same
time, will take into account a number of factors, including the quality
ratings, interest rates, yields, maturity dates, call prices, and refunding
and sinking fund provisions of the securities under consideration, as well as
historical yield spreads and current economic information. The success of
short-term trading will depend upon the ability of the investment manager, or
sub-investment manager, to evaluate particular securities, to anticipate
relevant market factors, including trends of interest rates and earnings and
variations from such trends, to obtain relevant information, to evaluate it
promptly, and to take advantage of its evaluations by completing transactions
on a favorable basis. It is expected that the expenses involved in short-term
trading, which would not be incurred by an investment company which does not
use this portfolio technique, will be taken into account.
 
FOREIGN CURRENCY EXCHANGE TRANSACTIONS
 
  The foreign currency exchange transactions of those Portfolios that can
invest in foreign securities may be conducted on a spot, i.e., cash, basis at
the spot rate for purchasing or selling currency prevailing in the foreign
exchange market. Certain of such Portfolios also have authority to deal in
forward foreign currency exchange contracts involving currencies of the
different countries in which they invest as a hedge against possible
variations in the foreign exchange rate between these currencies. The
Portfolios' hedging transactions in forward foreign currency exchange
contracts may involve either specific transactions or portfolio positions.
Transaction
 
                                       3
<PAGE>
 
   
hedging is the forward purchase or sale of foreign currency with respect to
specific receivables or payables of the Portfolio accruing in connection with
the purchase and sale of its securities denominated in foreign currencies.
Portfolio hedging is the use of forward foreign currency exchange contracts
with respect to the Portfolio's security positions denominated or quoted in
such foreign currencies. Except as described in the Fund's Prospectus as to
the Mid Cap Growth, Global Equity, International Balanced, International
Equity Index, International Equities, and Strategic Bond Portfolios, the
Portfolios may not engage in portfolio hedging with respect to the currency of
a particular country to an extent greater than the aggregate market value (at
the time of making such sale) of the securities which the Portfolio holds
denominated or quoted in that particular foreign country. The Portfolios may
or may not attempt to hedge all of their foreign portfolio positions and will
enter into such transactions only to the extent, if any, deemed appropriate by
the sub-investment managers. The Portfolios will not use forward foreign
currency exchange contracts for the purpose of leveraging the Portfolio's
currency exposure.     
   
  In implementing the above-described currency techniques, the Mid Cap Growth,
Global Equity, International Balanced and International Equity Index
Portfolios may use forward contracts in a "proxy" currency instead of the
foreign currency being hedged. A "proxy" currency is one that the sub-
investment manager believes will bear a close relationship to the currency
being hedged and believes will at least equal the performance of such currency
relative to the U.S. dollar. A proxy currency might be used, for example,
where the market for such currency was more liquid or involved lower
transaction costs than the market being hedged. The Portfolios do not intend
to speculate in foreign currencies. Nevertheless, changes in the value of the
currency being hedged may not correspond to changes in the value of the proxy
currency as expected, which could result in the currency hedge being more
favorable or less favorable to the Portfolio.     
 
  If a Portfolio enters into a portfolio hedging transaction, the Portfolio
may cover outstanding forward currency sale contracts by maintaining portfolio
securities denominated in the currency of such contracts or of an appropriate
proxy currency. To the extent a Portfolio does not thus cover all of its
forward currency sales positions with its portfolio securities, or if it has
outstanding any forward currency purchase contracts, its custodian bank will
segregate cash or liquid assets in a separate account of the Portfolio in an
amount at all times at least equal to the value of the Portfolio's net
obligation with respect to forward contracts in a particular currency or, in
the case of the International Balanced Portfolio only, the Portfolio's net
"out of the money" obligation (if any) with respect to all of the Portfolio's
outstanding forward currency contracts. If the value of the portfolio
securities used to cover a position or the value of the assets in the separate
account declines, the Portfolio will find additional cover or additional cash
or liquid assets will be placed in the account so that the value of the
account will equal the amount of the Portfolio's net obligation with respect
to such contracts as described in the preceding sentence.
   
  At the maturity of a forward currency sale contract, a Portfolio may either
sell a portfolio security and make delivery of the foreign currency, or it may
retain the security and terminate its contractual obligation to deliver the
foreign currency by purchasing an "offsetting" contract obligating it to
purchase, on the same maturity date, the same amount of the foreign currency.
Similarly, at the maturity of a foreign currency purchase contract, a
Portfolio may take delivery of the currency, if needed to purchase a portfolio
security, or may enter into an offsetting transaction to close out its
position. The Portfolio may realize a gain or loss from currency transactions.
    
  Hedging against a decline in the value of a currency does not eliminate
fluctuations in the prices of portfolio securities or prevent losses if the
prices of such securities decline. Such transactions also preclude the
opportunity for gain if the value of the hedged currency should rise.
Moreover, it may not be possible for the Portfolios to hedge against a
devaluation that is so generally anticipated that the Portfolios are not able
to contract to sell the
 
                                       4
<PAGE>
 
currency at a price above the devaluation level it anticipates. The cost to
the Portfolios of engaging in foreign currency exchange transactions varies
with such factors as the currency involved, the length of the contract period
and the market conditions then prevailing. Since transactions in foreign
currency exchange are usually conducted on a principal basis, no fees or
commissions are involved.
 
FORWARD COMMITMENTS
   
  As described in the Fund's Prospectus, the Equity Index, Large Cap Value,
Mid Cap Value, Mid Cap Growth, Special Opportunities, Small/Mid Cap CORE
Equity, Small Cap Value, Small Cap Growth, Global Equity, International
Balanced, International Equity Index, International Equities, International
Opportunities, Emerging Markets Equity, Short-Term U.S. Government,
Diversified Bond Index, Sovereign Bond, Strategic Bond, and High Yield Bond
Portfolios may enter into contracts to purchase securities for a fixed price
at a future date beyond customary settlement time ("forward commitments")
because new issues of securities are typically offered on such a basis. On the
date when the Portfolio enters into a forward commitment, it will segregate in
a separate account cash or liquid assets denominated in the currency of the
security contracted to be purchased having a value at least equal to the
amount required to assure the availability of funds for the purchase price.
These assets will be valued at market daily and additional cash or liquid
assets will be added to the separate account to the extent the total value of
the assets in the account declines below the amount of the commitment.     
 
REPURCHASE AGREEMENTS
 
  As described in the Fund's Prospectus, a Portfolio may enter into repurchase
agreements with respect to its portfolio securities. Each such Portfolio has
established a procedure providing that the securities serving as collateral
for each repurchase agreement must be delivered to the Portfolio's custodian
or sub-custodian either physically or in book-entry form and that the
collateral must be marked-to-market daily to ensure that each repurchase
agreement is fully collateralized at all times. In the event of a bankruptcy
or other default by a seller of a repurchase agreement, the Portfolio could
experience delays in liquidating the underlying securities and could
experience losses, including the possible decline in the value of the
underlying securities during the period while the Portfolio seeks to enforce
its rights thereto, possible subnormal levels of income and lack of access to
income during this period, and expenses of enforcing its rights.
 
LENDING OF PORTFOLIO SECURITIES
   
  In order to generate additional income, the Equity Index, Large Cap Value,
Mid Cap Value, Mid Cap Growth, Special Opportunities, Small/Mid Cap CORE
Equity, Small Cap Value, Small Cap Growth, Global Equity, International
Balanced, International Equity Index, International Opportunities, Emerging
Markets Equity, Short-Term U.S. Government, Diversified Bond Index, Strategic
Bond, and High Yield Bond Portfolios may from time to time lend securities
from its portfolio to brokers, dealers and financial institutions such as
banks and trust companies. Such loans will be secured by collateral consisting
of cash or U.S. Government securities, which will be maintained in an amount
equal to at least 100% of the current market value of the loaned securities.
During the period of the loan, the Portfolio receives the income on the loaned
securities and the compensation for making the loan and thereby increases its
return. Cash collateral may be invested in short-term securities, which will
increase the current income of the Portfolio. Such loans will not be for more
than 60 days and will be terminable by the Portfolio at any time. The
Portfolio will have the right to regain record ownership of loaned securities
in order to exercise rights of a holder thereof including receiving interest
or other distributions or exercising voting rights. The Portfolio may pay
reasonable fees to persons unaffiliated with the Portfolio for     
 
                                       5

services in arranging such loans. Lending of portfolio securities involves a
risk of failure by the borrower to return the loaned securities, in which
event the Portfolio may incur a loss.
 
                  TYPES OF INVESTMENT INSTRUMENTS AND RATINGS
 
FOREIGN SECURITIES
 
  As discussed in the prospectus under "Risks Factors--Risks of Foreign
Securities," all of the Portfolios may invest at least some of their assets in
foreign securities, except for the Real Estate Equity and Short-Term U.S.
Government Portfolios. The purchase of foreign securities could involve risks
not associated with domestic securities. Among others, there may be risks of
political and economic instability, foreign taxes, liquidity, predictability
of international trade patterns, and fluctuations in rates of currency
exchange. Less information with respect to a foreign issuer may be publicly
available, the accounting, auditing, and financial standards may be lower, the
issuer may be subjected to less regulation or to a greater risk of
expropriation or confiscatory taxation and, in the event of default, a
judgment against the issuer may be difficult to obtain or enforce.
 
  The securities markets of many countries have in the past moved relatively
independent of one another, due to differing economic, financial, political
and social factors. When markets move in different directions, there may be a
corresponding reduction in risk for those Portfolios that can invest in
foreign securities as a whole. This lack of correlation among the movements in
the world's securities markets may also affect unrealized gains these
Portfolios may derive from movements in any one market. If the securities of
markets moving in different directions are combined in any of these
Portfolios, total volatility of the Portfolio is reduced.
 
  Because these Portfolios may invest in securities denominated or quoted in
currencies other than United States dollars, changes in foreign currency
exchange rates will affect the value of the securities. Exchange rates may not
move in the same direction as the securities markets in a particular country.
As a result, the gain realized on a foreign investment may be offset by an
unfavorable exchange rate.
   
  The Special Opportunities, Global Equity, International Balanced,
International Equity Index, International Equities, International
Opportunities, Emerging Markets Equity, Strategic Bond, and High Yield Bond
Portfolios may invest in companies located in emerging countries which,
compared to the U.S. and other developed countries, may have relatively
unstable governments, economies and currencies, based on only a few
industries, and securities markets which trade only a small number of
securities. Prices on exchanges located in developing countries tend to be
volatile and, in the past, securities traded on those exchanges have offered a
greater potential for gain (and loss) than securities traded on exchanges in
the U.S. and more developed countries.     
 
  The Portfolios that are authorized to purchase foreign securities may also
do so in the form of American Depositary Receipts (ADRs), European Depositary
Receipts (EDRs) or other securities representing underlying shares of foreign
issuers. These securities may not necesssarily be denominated in the same
currency as the securities into which they may be converted but rather in the
currency of the market in which they are traded. ADRs are receipts typically
issued by an American bank or trust company which evidence ownership of
underlying securities issued by a foreign corporation. EDRs are receipts
issued in Europe by banks or depositories which evidence a similar ownership
arrangement. Generally, ADRs, in registered form, are designed for use in U.S.
securities markets and EDRs, in bearer form, are designed for use in European
securities markets.
 
  The Portfolios that are authorized to purchase foreign securities may invest
in U.S. dollar denominated debt securities issued by foreign corporations and
publicly traded in the United States (Yankees) or Europe (Euros).
 
                                       6
<PAGE>
 
Because Yankees and Euros are U.S. dollar denominated, the risks associated
with foreign currency conversions are not present.
 
DEBT SECURITIES GENERALLY
 
  The value of the debt securities in any Portfolio can be expected to vary
inversely to changes in prevailing interest rates, with the amount of such
variation depending primarily on the remaining duration of the security. Long-
term obligations usually fluctuate more in value than short-term obligations.
If interest rates increase after a security is purchased, the security, if
sold, could be sold for a loss. On the other hand, if interest rates decline
after a purchase, the security, if sold, could be sold at a profit. If,
however, the security is held to maturity, no gain or loss will be realized as
a result of interest rate fluctuations, although the day-to-day valuation of
the Portfolio could fluctuate. As in the case of any other security,
substantial redemptions could require a Portfolio to sell debt securities at a
time when a sale might not be favorable. The value of a portfolio security may
also be affected by other factors, including factors bearing on the
creditworthiness of its issuer. Generally, lower-rated securities are subject
to greater price fluctuations.
 
  Securities having one of the four highest rating categories for debt
securities as defined by Moody's Investors Services, Inc. (Aaa, Aa, A, or Baa)
or Standard and Poor's Corporation (AAA, AA, A, or BBB) or, if unrated,
determined to be of comparable quality by the sub-investment manager, are
referred to as investment grade. The meanings of such ratings are discussed
further under "Corporate Bond Ratings," below.
 
DEBT SECURITIES OF THE INTERNATIONAL EQUITIES PORTFOLIO
 
  It is the intention of the International Equities Portfolio generally to
invest in debt securities only for temporary defensive purposes. Accordingly,
when the sub-investment managers believe unfavorable investment conditions
exist requiring the Portfolio to assume a temporary defensive investment
posture, the Portfolio may hold cash or invest all or a portion of its assets
in short-term domestic as well as foreign instruments, including: short-term
U.S. Government securities and repurchase agreements in connection with such
instruments; bank certificates of deposit, bankers' acceptances, time deposits
and letters of credit; and commercial paper (including so called Section 4(2)
paper) rated at least A-1 or A-2 by Standard & Poor's Corporation ("S&P") or
P-1 or P-2 by Moody's Investors Service, Inc. ("Moody's") or if unrated
considered by the sub-investment managers to be of comparable quality. The
Portfolio's temporary defensive investments may also include: investment grade
debt obligations of U.S companies; commercial paper and corporate debt
obligations not satisfying the above credit standards if they are (a) subject
to demand features or puts or (b) guaranteed as to principal and interest by a
domestic or foreign bank having total assets in excess of $1 billion, by a
corporation whose commercial paper may be purchased by the Portfolio or by a
foreign government having an existing debt security rated investment grade by
S&P or Moody's; and other short-term investments which the Fund's Trustees
determine present minimal credit risks and which are of "high quality" as
determined by any major rating service, or in the case of an instrument that
is not rated, of comparable quality as determined by the sub-investment
managers. If the rating of a debt security is reduced below the minimums
discussed above, the sub-investment managers will consider whatever action is
appropriate consistent with the Portfolio's investment objectives and
policies.
 
SOVEREIGN BOND PORTFOLIO SECURITIES
 
  It is contemplated that at least 75% of the value of the Sovereign Bond
Portfolio's total investment in debt securities (other than commercial paper)
will be represented by debt securities which have, at the time of purchase, an
investment grade rating and debt securities of banks and other issuers which,
although not rated as
 
                                       7
<PAGE>
 
a matter of policy by either Moody's or S&P, are considered by the sub-
investment manager to have comparable investment quality. The Portfolio will,
as a rule, seek to purchase debt securities which have protection against
immediate refunding. In recent years, corporate debt securities have
frequently been issued which have refunding protection for a period of five to
ten years and, in some cases, longer, although there can be no assurance that
securities containing similar provisions will continue to be issued.
 
  The Portfolio may purchase corporate debt securities bearing fixed interest
as well as those which carry certain equity features, such as conversion or
exchange rights or warrants for the acquisition of stock of the same or a
different issuer, or participations based on revenues, sales, or profits. The
Portfolio will not exercise any such conversion, exchange or purchase rights
if, at the time, the value of all equity interests so owned would exceed 10%
of the Portfolio's total assets taken at market value.
 
  The Portfolio may also purchase U.S. dollar-denominated securities issued by
foreign corporations and publicly traded in either the United States (Yankees)
or Europe (Euros).
 
  The Portfolio may include debt securities which sell at substantial
discounts from par. These securities are low coupon bonds which, during
periods of high interest rates, because of their lower acquisition cost, tend
to sell on a yield basis approximating current interest rates.
   
DEBT SECURITIES OF THE HIGH YIELD BOND PORTFOLIO     
   
  Under normal market and economic conditions, the High Yield Bond Portfolio
will invest at least 65% of its assets in debt obligations considered to be
below investment grade, including high yield/high risk or "junk" bonds,
preferred stock and convertible securities. High yield/high risk securities
are considered speculative and involve greater risk of default or price
changes due to changes in the issuer's creditworthiness than higher-rated
securities, and are more sensitive to changes in the issuer's capacity to pay.
Investing in high yield/high risk securities is an aggressive approach to
income investing. The 1980s saw a dramatic increase in the use of high
yield/high risk securities to finance highly leveraged corporate acquisitions
and restructurings. Past experience may not provide an accurate indication of
future performance of high yield/high risk securities, especially during
periods of economic recession. In fact, from 1989 to 1991, the percentage of
high yield/high risk securities that defaulted rose significantly above prior
levels.     
   
  High yield/high risk securities may be thinly traded, which can adversely
affect the prices at which they can be sold and can result in high transaction
costs. If market quotations are not available, these securities will be valued
in accordance with standards set by the Board of Trustees, including the use
of outside pricing services. Judgment plays a greater role in valuing high
yield/high risk securities then in the case of other securities for which more
extensive quotations and last-sale information are available. Adverse
publicity and changing investor perceptions may affect the ability of outside
pricing services used by the Portfolio to value its portfolio securities, and
the Portfolio's ability to dispose of the lower-rated bonds. The market prices
of high yield/high risk securities may decline significantly in periods of
general economic difficulty, which may follow periods of rising interest
rates. During an economic downturn or a prolonged period of rising interest
rates, the ability of issuers of lower-rated debt to service their payment
obligations, meet projected goals, or obtain additional financing may be
impaired. The Portfolio may choose, at its own expense or in conjunction with
others, to pursue litigation or otherwise exercise its rights as a security
holder to seek to protect the interests of security holders, if it determines
this to be in the interest of Portfolio investors.     
 
                                       8
<PAGE>
 
   
  The considerations discussed above for lower-rated debt securities also are
applicable to lower quality unrated debt instruments of all types, including
loans and other direct indebtedness of businesses with poor credit standing.
Unrated debt instruments are not necessarily of lower quality than rated
securities but they may not be attractive to as many buyers.     
 
U.S. GOVERNMENT OBLIGATIONS
 
  U.S. Government obligations are bills, certificates of indebtedness, notes
and bonds issued or guaranteed as to principal or interest by the United
States or by agencies or authorities controlled or supervised by and acting as
instrumentalities of the U.S. Government established under the authority
granted by Congress, including, but not limited to, the Tennessee Valley
Authority, Federal Home Loan Banks, Federal Land Banks, Farm Credit System,
the Federal National Mortgage Association, World Bank, Inter-American
Development Bank, Student Loan Marketing Association, Financing Corporation,
Asian Development Bank, Federal Housing Administration, Agency for
International Development, Federal Home Loan Mortgage Corporation, Government
Trust Certificates, Private Export Funding Corporation, and Small Business
Administration. Some obligations of U.S. Government agencies, authorities, and
other instrumentalities are supported by the full faith and credit of the U.S.
Treasury; others by the right of the issuer to borrow from the Treasury; and
others only by the credit of the issuing agency, authority, or other
instrumentality. U.S. Government obligations are primarily used in the Money
Market and the Short-Term U.S. Government Portfolios. All of the other
Portfolios may also invest in U.S. Government obligations to some extent.
 
OTHER MONEY MARKET PORTFOLIO SECURITIES
 
  Certificates of Deposit--are certificates issued against funds deposited in
a bank, are for a definite period of time, earn a specified rate of return,
and are normally negotiable.
 
  Bankers' Acceptances--are short-term credit instruments issued by
corporations to finance the import, export, transfer or storage of goods. They
are termed "accepted" when a bank guarantees their payment at maturity. These
instruments reflect the obligation of both the bank and the drawer to pay the
face amount of the instrument at maturity.
 
  Commercial Paper--refers to promissory notes issued by corporations to
finance their short-term credit needs. See "Commercial Paper Ratings," below.
 
  Corporate Obligations--include bonds, debentures, and notes issued by
corporations in order to finance longer term credit needs. See "Corporate Bond
Ratings," below. These instruments may be considered money market securities
when they have a relatively short remaining maturity.
 
  The foregoing types of money market instruments are used primarily by the
Money Market Portfolio, but may also be used by each of the other Portfolios
to some extent.
 
COMMERCIAL PAPER RATINGS
 
  The rating A-1 is the highest rating assigned by Standard & Poor's
Corporation ("S&P") to commercial paper which is considered by S&P to have the
following characteristics: liquidity ratios of the issuer are adequate to meet
cash requirements; long-term senior debt is rated "A" or better; the issuer
has access to at least two additional channels of borrowing; basic earnings
and cash flow have an upward trend with allowance made for unusual
circumstances; typically, the issuer's industry is well established and the
issuer has a strong position within the industry.
 
                                       9
<PAGE>
 
  The rating P-1 is the highest commercial paper rating assigned by Moody's
Investors Services, Inc. (Moody's). Among the factors considered by Moody's in
assigning ratings are the following: (1) evaluation of the management of the
issuer; (2) economic evaluation of the issuer's industry or industries and an
appraisal of speculative-type risks which may be inherent in certain areas;
(3) evaluation of the issuer's products in relation to competition and
customer acceptance; (4) liquidity; (5) amount and quality of long-term debt;
(6) trend of earnings over a period of ten years; (7) financial strength of a
parent company and the relationships which exist with the issuer; and (8)
recognition by the management of obligations which may be present or may arise
as a result of public interest questions and preparations to meet such
obligations.
 
  The rating F-1 is the highest rating assigned by Fitch Investors Service.
 
CORPORATE BOND RATINGS
   
  Moody's Investors Service, Inc., describes its ratings for corporate bonds
as follows:     
 
  Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edge." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements
are likely to change, such changes as can be visualized are most unlikely to
impair the fundamentally strong position of such issues.
 
  Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high
grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long term risks appear somewhat larger than in Aaa
securities.
 
  Bonds which are rated A possess many favorable investment attributes and are
to be considered as upper medium grade obligations. Factors giving security to
principal and interest are considered adequate but elements may be present
which suggest a susceptibility to impairment some time in the future.
 
  Bonds which are rated Baa are considered as medium grade obligations, i.e.,
they are neither highly protected nor poorly secured. Interest payments and
principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
   
  Bonds which are rated Ba have speculative elements and their future cannot
be considered as well assured. The protection of interest and principal
payments may be very moderate and thereby not well safeguarded during both
good and bad times over the future. Bonds in this class are characterized by
uncertainty of position.     
   
  Bonds which are rated B generally lack characteristics of a desirable
investment; assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.     
   
  Bonds which are rated Caa are of poor standing. Issues may be in default or
there may be present elements of danger with respect to principal or interest.
       
  Bonds which are rated Ca are speculative in a high degree. They are often in
default or have other marked shortcomings.     
 
                                      10
<PAGE>
 
   
  Bonds which are rated C are the lowest rated class of bonds. They can be
regarded as having extremely poor prospects of ever attaining any real
investment standing.     
   
  Standard & Poor's Corporation describes its ratings for corporate bonds as
follows:     
     
    AAA--This is the highest rating assigned by Standard & Poor's to a debt
  obligation and indicates an extremely strong capacity to pay principal and
  interest.     
     
    AA--Bonds rated AA also qualify as high-quality obligations. Capacity to
  pay principal and interest is very strong, and in the majority of
  instances, they differ from AAA issues only in small degree.     
     
    A--Bonds rated A have a strong capacity to pay principal and interest,
  although they are somewhat more susceptible to the adverse effects of
  changes in circumstances and economic conditions.     
     
    BBB--Bonds rated BBB are regarded as having an adequate capacity to pay
  principal and interest. Whereas they normally exhibit protection
  parameters, adverse economic conditions or changing circumstances are more
  likely to lead to a weakened capacity to pay principal and interest for
  bonds in this category than for bonds in the A category.     
     
    BB, B, CCC, CC, C--Bonds rated in these categories are regarded, on
  balance, as predominantly speculative with respect to capacity to pay
  interest and repay principal in accordance with the terms of the
  obligation. BB indicates the lowest degree of speculation and C the highest
  degree of speculation. While this debt will likely have some quality and
  protective characteristics, these are outweighed by large uncertainties or
  major risk exposures to adverse conditions.     
     
    C1--This rating is reserved for income bonds on which no interest in
  being paid.     
     
    D--Bonds rated D are in default and payment of interest and/or repayment
  of principal is in arrears.     
 
STANDARD AND POOR'S DEPOSITORY RECEIPTS
 
  The Equity Index Portfolio may, consistent with its objectives, purchase
Standard & Poor's Depository Receipts ("SPDRs"). SPDRs are American Stock
Exchange-traded securities that represent ownership in the SPDR Trust, a trust
which has been established to accumulate and hold a portfolio of common stocks
that is intended to track the price performance and dividend yield of the S&P
500. This trust is sponsored by a subsidiary of the American Stock Exchange.
SPDRs may be used for several reasons, including but not limited to:
facilitating the handling of cash flows or trading, or reducing transaction
costs. The use of SPDRs would introduce additional risk to the Portfolio as
the price movement of the instrument does not perfectly correlate with the
price action of the underlying index.
 
FINANCIAL FUTURES CONTRACTS
 
  A public market currently exists for interest rate futures contracts on
United States Treasury Bills, United States Treasury Notes and bank
certificates of deposit. A public market currently exists for stock index
futures contracts based on the Standard & Poor's 500 Stock Index, the Standard
& Poor's Midcap Index, the New York Stock Exchange Composite Index and the
Value Line Stock Index. Stock index futures contracts bind purchaser and
seller to delivery at a future date specified in the contract of a cash amount
equal to a multiple of the difference between the value of a specified stock
index on that date and settlement price specified by the contract. That is,
the seller of the futures contract must pay and the purchaser would receive a
multiple of any excess of the value of the index over the settlement price,
and the purchaser must pay and the seller would receive a multiple of any
excess of the settlement price over the value of the index. Multiples reflect
the denominations in which the contracts are traded.
 
                                      11
<PAGE>
 
   
  All of the Portfolios (except for the Growth & Income, Real Estate Equity,
International Equities, Diversified Bond Index, and Money Market Portfolios)
may use the above-described and other available exchange traded financial
futures contracts, and options thereon, subject to the limitations set forth
herein and in the Fund's prospectus.     
 
OPTIONS ON FINANCIAL FUTURES CONTRACTS
 
  The writer of an option on a financial futures contract agrees to assume a
position in such financial futures contract if the purchaser exercises the
option and thereby assumes the opposite position in the financial futures
contract. A party that writes an option receives a premium for doing so, and
the party that purchases an option pays a premium therefor. The option writer
incurs the risk that the option will be exercised and the writer will suffer a
loss on the futures contract position it is thus required to assume that
exceeds the premium the writer received.
 
  If the price of the debt instrument or stock index on which the futures
contract is based increases (in the case of a put option written by the
Portfolio) or decreases (in the case of a call option written by the
Portfolio), the Portfolio may incur losses that exceed the amount of the
premium received by the Portfolio for writing the option. Such losses may
arise because an option written by the Portfolio on a futures contract
requires the Portfolio to pay any amount by which the fluctuating price of the
underlying debt instrument or index exceeds (in the case of a put option) or
is less than (in the case of a call option) the price specified in the futures
contract to which the option relates.
 
INTEREST RATE OPTIONS
 
  After payment of a specified premium at the time an interest rate option is
entered into, the purchaser of a call interest rate option obtains the right
to receive specified debt securities upon exercise of the option in exchange
for payment of a specified exercise price. The purchaser of a put option
obtains the right to sell the specified debt securities upon exercise of the
option and to receive the exercise price therefor. The writer of the interest
rate option receives a premium but has the obligation, upon exercise of the
option, to deliver the subject securities in exchange for the exercise price
(in the case of a call option) or to purchase the subject securities at the
exercise price (in the case of a put option).
   
  Securities for which interest rate options are currently traded include
United States Treasury Bonds and United States Treasury Notes. Subject to the
limitations and conditions elsewhere set forth in this Statement of Additional
Information and in the Fund Prospectus, the Mid Cap Growth, Special
Opportunities, Small Cap Value, Small Cap Growth, Global Equity, International
Balanced, Short-Term U.S. Government, Strategic Bond, and High Yield Bond
Portfolios may use these and such other interest rate options as may be
available.     
 
MARGIN REQUIREMENTS FOR FUTURES AND OPTIONS
 
  When futures contracts are traded, both buyer and seller are required to
post an initial margin of cash or United States Treasury Bills equaling as
much as 5 to 10 percent or more of the contract settlement price. The nature
of the margin requirements in futures transactions differs from traditional
margin payments made in securities transactions in that margins for futures
contracts do not involve the borrowing of funds by the customer to finance the
transaction. Instead, a customer's margin on a futures contract represents a
good faith deposit securing the customer's contractual obligations under the
futures contract. If the market moves against the Fund, so that a Portfolio
has a net loss on its outstanding futures contracts for a given day, the
Portfolio generally will
 
                                      12
<PAGE>
 
be required to post additional margin to that extent. The margin deposit is
returned, assuming the Fund's obligations have been met, when the futures
contract is terminated.
 
  Similar margin requirements will apply in connection with any transactions
in which a Portfolio writes options on futures contracts, options on
securities indexes, or interest rate options.
 
STOCK INDEX OPTIONS
 
  After payment of a specified premium at the time a stock index option is
entered into, the purchaser of a stock index call option obtains the right to
receive a sum of money upon exercise of the option equal to a multiple of the
excess of a specified stock index on the exercise date over the exercise or
"strike" price specified by the option. The purchaser of a put option obtains
the right to receive a sum of money upon exercise of the option equal to a
multiple of any excess of the strike price over the stock index. The writer of
a call or put stock index option receives a premium, but has the obligation,
upon exercise of the option, to pay a multiple of the difference between the
index and the strike price.
   
  Stock indexes for which options are currently traded include the Standard &
Poor's 100 and Standard & Poor's 500 Indexes. Subject to the limitations set
forth herein and in the Fund's prospectus, the Managed, Equity Index, Large
Cap Value, Large Cap Growth, Mid Cap Value, Mid Cap Growth, Special
Opportunities, Small/Mid Cap CORE Equity Portfolio, Small Cap Value, Small Cap
Growth, Global Equity, International Balanced, International Equity Index,
International Opportunities, and Emerging Markets Growth Portfolios may use
these options and options on such other indexes as may be available.     
 
OTHER DERIVATIVE TRANSACTIONS
   
  Subject to the conditions set forth in the Fund's Prospectus, the Global
Equity, International Balanced, International Equity Index, Emerging Markets
Equity, Strategic Bond, and High Yield Bond Portfolios may use swaps, caps,
floors and collars. Provided the contract so permits, a Portfolio will usually
enter into swaps on a net basis; that is, the two payment streams are netted
out in a cash settlement on the payment date or dates specified in the
instrument, with the Portfolio receiving or paying, as the case may be, only
the net amount of the two payments.     
 
  Each Portfolio will maintain cash or liquid high grade debt securities in a
segregated account with its custodian in an amount sufficient at all times to
cover its current obligations under swaps, caps, floors and collars. If a
Portfolio enters into a swap agreement on a net basis, it will segregate
assets with a daily value at least equal to the excess, if any, of the
Portfolio's accrued obligations under the swap agreement over the accrued
amount the Portfolio is entitled to receive under the agreement. If a
Portfolio enters into a swap agreement on other than a net basis, or sells a
cap, floor or collar, it will segregate assets with a daily value at least
equal to the full amount of the Portfolio's accrued obligations under the
agreement.
   
  None of these Portfolios will enter into any swap, cap, floor, or collar,
unless the other party to the transaction (the "Counterparty") is deemed
creditworthy by the sub-investment manager. If a Counterparty defaults, the
Portfolio may have contractual remedies pursuant to the agreements related to
the transaction. The swap market has grown substantially in recent years, with
a large number of banks and investment banking firms acting both as principals
and as agents utilizing standardized swap documentation. As a result, the swap
market has become relatively liquid. Caps, floors and collars are more recent
innovations for which standardized documentation has not yet been fully
developed and, for that reason, they are less liquid than swaps.     
 
                                      13
<PAGE>
 
  The liquidity of swaps, caps, floors and collars will be determined by the
sub-investment manager based on various factors, including (1) the frequency
of trades and quotations, (2) the number of dealers and prospective purchasers
in the marketplace, (3) dealer undertakings to make a market, (4) the nature
of the instrument (including any demand or tender features) and (5) the nature
of the marketplace for trades (including the ability to assign or offset a
Portfolio's rights and obligations relating to the investment). Such
determination will govern whether the instrument will be deemed within the 15%
restriction on investments in securities that are not readily marketable.
 
  The federal income tax treatment with respect to swaps, caps, floors, and
collars may impose limitations on the extent to which a Portfolio may engage
in such transactions.
 
                            INVESTMENT RESTRICTIONS
 
  The Fund has adopted the following restrictions relating to the investment
of each Portfolio's assets. These restrictions are fundamental policies and
may not be changed for any Portfolio without the approval of a majority of the
outstanding voting shares of each affected Portfolio. (As used in the
Prospectus and this Statement of Additional Information, the term "majority of
the outstanding voting shares" means the lesser of (1) 67% of the shares
represented at a meeting at which more than 50% of the outstanding shares are
represented or (2) more than 50% of the outstanding shares.) A change in
policy affecting only one Portfolio may be effected with the approval of the
majority of the outstanding voting shares of that Portfolio, without the
approval of a majority of the outstanding voting shares of any other Portfolio
or of the entire Fund.
 
  No Portfolio will:
 
    (1) Purchase real estate or any interest therein, except through the
  purchase of corporate or certain government securities (including
  securities secured by a mortgage or a leasehold interest or other interest
  in real estate). A security issued by a real estate or mortgage investment
  trust or an interest in a pool of real estate mortgage loans is not treated
  as an interest in real estate.
     
    (2) Make loans, other than through the acquisition of obligations in
  which the Portfolio may invest consistent with its objective and investment
  policies, except that the Equity Index, Large Cap Value, Mid Cap Value, Mid
  Cap Growth, Special Opportunities, Small/Mid Cap CORE Equity, Small Cap

  securities of the investment company having an aggregate value in excess of
  5% of the Portfolio's total assets, (c) securities of investment companies

  or (d) together with investment companies having the same investment
  adviser as the Portfolio (and companies controlled by such investment
  companies), more than 10% of the outstanding voting stock of any registered

    (10) Purchase securities of any issuer, if (a) with respect to 75% of the
  market value of its total assets, more than 5% of the Portfolio's total
  assets taken at market value would at the time be invested in the

  the time result in more than 10% of the outstanding voting securities of
  such

  issuer being held by the Portfolio. This restriction shall not apply to the
  Mid Cap Growth, Special Opportunities, or International Balanced
  Portfolios.     
 
    (11) Issue senior securities. For the purposes of this restriction, the
  following shall not be deemed to be the issuance of a senior security: the
  use of futures contracts as permitted by restriction 3, above; the use of
  option contracts as permitted by restriction 3, above; and the use of
  foreign currency contracts.
   
  The Equity Index, Large Cap Value, Mid Cap Value, Mid Cap Growth, Special
Opportunities, Small/Mid Cap CORE Equity, Small Cap Value, Small Cap Growth,
Global Equity, International Balanced, International Equity Index,
International Equities, International Opportunities, Emerging Markets Equity,
Diversified Bond Index, Sovereign Bond, Strategic Bond, and High Yield Bond
Portfolios will not purchase the securities of issuers conducting their
principal business activity in the same industry if, immediately after such
purchase, the value of the Portfolio's investments in such industry would
exceed 25% of its total assets taken at market value. For the purpose of this
restriction, telephone, water, gas and electric public utilities are each
regarded as separate industries, and wholly-owned finance companies are
considered to be in the industry of their parents if their activities are
primarily related to financing the activities of their parent.     
   
  The Special Opportunities, International Equities, and Short-Term U.S.
Government Portfolios will not purchase any security, including any repurchase
agreement maturing in more than seven days, which is subject to legal or
contractual delays in or restrictions on resale, or which is not directly
marketable, if more than 10% of the assets of the Portfolio, taken at market
value, would be invested in such securities.     
 
  For purposes of any restrictions or limitation to which the Fund is subject,
no Portfolio, by entering into any futures contract or acquiring or writing
any option thereon or on any security or market index, shall be deemed
 
    (1) to have acquired or invested in any securities of any exchange or
  clearing corporation for any such instrument or
 
    (2) to have acquired or invested in any debt obligations or in any stocks
  comprising indexes on which such instrument is based, but which the
  Portfolio does not hold directly in its portfolio.

Portfolios.     
   
  Under the Investment Management Agreements, for any fiscal year in which the
normal operating costs and expenses of any Portfolio of the Series, exclusive
of the investment advisory fee, interest, brokerage commissions, taxes and
extraordinary expenses outside the control of John Hancock exceed 0.25% of
that Portfolio's average daily net assets, John Hancock will reimburse that
Portfolio promptly after the end of the fiscal year in an amount equal to such
excess. These reimbursements have been as follows for the past three years:

UNDERWRITING AND INDEMNITY AGREEMENT
 
  The offering of the Fund's shares is continuous. Pursuant to an Underwriting
and Indemnity Agreement, as amended May 1, 1997, John Hancock Distributors,
Inc. ("Distributors") serves as the Fund's principal underwriter. Neither
Distributors nor John Hancock receives any additional compensation from the
Fund for the services it performs pursuant to the Underwriting Agreement.
Distributors is a wholly-owned subsidiary of John Hancock located at 197
Clarendon Street, Boston, MA 02117.
 
CUSTODIAN AGREEMENT
          
  State Street Bank and Trust Company of Boston, Massachusetts, is the
custodian of the assets of all Portfolios except for the Sovereign Bond
Portfolio pursuant to a revised Custodian Agreement dated as of January 30,
1995, and amended as of March 18, 1996    , and    . Investors Bank and Trust
Company ("IBT") of Boston, Massachusetts, is the custodian of the assets of
the Sovereign Bond Portfolio, pursuant to a custodian agreement dated as of
May 2, 1995. The custodians' duties include safeguarding and controlling the
Fund's cash and investments, handling the receipt and delivery of securities,
and collecting interest and dividends on the Fund's investments. Portfolio
securities purchased in the United States are maintained in the custody of
State Street Bank or IBT, as appropriate although such securities may be
deposited in the Book-entry system of the Federal Reserve System or with
Depository Trust Company. The Trustees of the Fund have determined that,
except as otherwise permitted under applicable Securities and Exchange
Commission "no-action" letters or exemptive orders, it is in the Fund's best
interest to hold foreign assets in qualified foreign banks and depositories
meeting the requirements of Rule 17f-5 under the Investment Company Act of
1940, as amended.     
 
INDEPENDENT AUDITORS
   
  LLP, 200 Clarendon Street, Boston, Massachusetts, are the independent
auditors of the Fund.     
 
                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION
 
  The Portfolios are charged with securities brokers' commissions, transfer
taxes, and other fees relating to their portfolio transactions. Expenses
identifiable to a particular Portfolio are charged to that Portfolio;
otherwise, expenses are prorated according to the size of the Portfolio.
Investments in debt securities are, however, generally traded on a net basis
through issuers or dealers acting for their own account as principals and not
as brokers; therefore, no brokerage commissions are payable on such
transactions, although the price to the Fund usually reflects a dealer
"spread" or "mark-up."

  In 1998, orders for the purchase and sale of Portfolio investments will be
placed by John Hancock with respect to the Money Market Portfolio and by the
respective sub-investment managers to the other Portfolios. These Investment
Managers place orders in such manner as, in their opinion, will offer the best
price and market for the execution of each transaction. In seeking the best
price and execution for equity securities traded only in the over-the-counter
market, they normally deal directly with the principal market-makers.     
 
  The Investment Managers are governed in the selection of brokers and dealers
and the negotiation of brokerage commission rates (or the payment of net
prices in the case of debt securities) by the reliability and quality of the
broker or dealer's services. Some weight is given the availability and value
of research and statistical assistance furnished by the broker or dealer to
the Investment Manager but it is not always possible to place a dollar value
on such information and services. Because it is only supplementary to the
Investment Managers' own research efforts, the receipt of research information
and statistical assistance is not expected to reduce their expenses
measurably. Research and statistical assistance typically furnished by brokers
or dealers includes analysts' reports on companies and industries, market
forecasts, and economic analyses. Brokers or dealers may also provide reports
on pertinent federal and state legislative developments and changes in
accounting practices; direct access by telephone or meetings with leading
research analysts throughout the financial community, corporate management
personnel, industry experts, leading economists and government officials;
comparative performance and evaluation and technical performance measurement
services; availability of economic advice; quotation services; and services
from recognized experts on investment matters of particular interest to the
sub-investment manager. In addition, the foregoing services may comprise the
use of or be delivered by computer systems whose software and hardware
components may be provided to the sub-investment manager as part of the
services. In any case in which the foregoing systems can be used for both
research and non-research purposes, the Investment Manager makes an
appropriate allocation of those uses and will permit brokers to provide only
the portion of the systems to be used for research services. Research and
statistical services furnished by brokers handling the Portfolios'
transactions may be used by the Investment Managers for the benefit of all of
the accounts managed by them and not all of such research and statistical
services may be used by the Investment Managers in connection with the
Portfolios.
 
                                      23
<PAGE>
 
   
  Except as described below with respect to the International Balanced
Portfolio, the Investment Managers or the Portfolios will not at any time make
a commitment pursuant to an agreement or understanding with a broker because
of research services provided. Nor, except as set forth below, will the
Investment Managers otherwise, through an internal allocation procedure,
direct brokerage upon any prescribed basis to a broker because of research
services provided. The sub-investment manager for each of the Small Cap Value,
Mid Cap Growth, and Mid Cap Value Portfolios may have an internal procedure
for allocating transactions in a manner consistent with its execution policy
to brokers that it has identified as providing superior executions, research,
or research related products or services which benefit its advisory clients,
including the Portfolio. In certain cases, the sub-investment manager of the
International Balanced Portfolio directs securities transactions for that
Portfolio to particular brokers, in recognition of research services the
broker has provided, pursuant to an understanding or agreement with the broker
or pursuant to the sub-investment manager's own internal allocation
procedures. During 1997, such transactions totaled $    , with related
commissions of $    .     
 
  Evaluations of the overall reasonableness of any broker's commissions are
made by the Investment Managers' traders for the Portfolios on the basis of
their experience and judgment. To the extent permitted by Section 28(e) of the
Securities Exchange Act of 1934, such traders are authorized to pay a
brokerage commission on a particular transaction in excess of what another
broker might have charged in recognition of the value of the broker's
brokerage or research services, although such authority is generally expected
to be used very infrequently. The Mid Cap Growth, Mid Cap Value, and
International Balanced Portfolios, however, may be more likely to use such
authority.
 
  Although the Investment Managers will be responsible for the allocation of
the Portfolios' brokerage, their policies and practices in this regard must be
consistent with the foregoing and will at all times be subject to review by
the Board of Trustees of the Fund.
 
  The brokerage transactions for those Portfolios that can invest in
securities of companies domiciled in countries other than the United States
are anticipated to be normally conducted on the stock exchanges or other
markets of those countries in which the particular security is traded. Fixed
commissions on foreign stock exchange transactions are generally higher than
negotiated commissions available in the United States. Moreover, there is
generally less government supervision and regulation of foreign stock
exchanges and broker-dealers than in the United States. Settlement periods in
non-U.S. markets may differ from the normal settlement period in the United
States.
   
  During 1997, certain Portfolios purchased the securities of their "regular
brokers or dealers," as that term is defined under Rule 10b-1 of the
Investment Company Act of 1940. The following table sets forth the name of
each such Portfolio, the identity of each broker or dealer, and the aggregate
value of the securities each such broker or dealer as of December 31, 1997.

                      THE TRUST'S ORGANIZATION AND SHARES
 
  On April 12, 1988, pursuant to an Agreement and Plan or Reorganization dated
February 2, 1988, a majority of the outstanding shares of each Portfolio of
John Hancock Variable Series Fund I, Inc., a Maryland corporation, voted its
reorganization as a Massachusetts business trust effective April 29, 1988. On
that date, all of the existing assets of John Hancock Variable Series Fund I,
Inc., and all of its obligations were transferred to John Hancock Variable
Series Trust I, a trust organized on February 25, 1988, for a number of full
and fractional shares of beneficial interest of the Trust equal to the number
of full and fractional shares of John Hancock Variable Series Fund I, Inc.,
then outstanding.
   
  The shares of beneficial interest of the Fund as reorganized are divided
into 24 series, each corresponding to one of the 24 Portfolios described in
the Fund's Prospectus. The Fund has the right to establish additional series
and issue additional shares without the consent of the shareholders.     
 
  The assets received by the Fund for the issuance or sale of shares of each
Portfolio and all income, earnings, profits, and proceeds thereof are
specifically allocated to that Portfolio. They constitute the underlying
assets of each Portfolio, are segregated on the books of the Fund, and are to
be charged with the expenses of such Portfolio. Any assets which are not
clearly allocable to a particular Portfolio or Portfolios are allocated in a
manner determined by the Board of Trustees. Accrued liabilities which are not
clearly allocable to one or more Portfolios would generally be allocated among
the Portfolios in proportion to their relative net assets before adjustment
for such unallocated liabilities. Each issued and outstanding share in a
Portfolio is entitled to participate equally in dividends and distributions
declared with respect to such Portfolio and in the net assets of such
Portfolio upon liquidation or dissolution remaining after satisfaction of
outstanding liabilities.
 
  The shares of each Portfolio, when issued, will be fully paid and non-
assessable, and will have no preference, preemptive, exchange or similar
rights. Shares do not have cumulative voting rights.
 
  Under the Declaration of Trust of the Fund, the Fund is not required to hold
an Annual Meeting. Normally there will be no shareholder meetings for the
purpose of electing Trustees unless and until fewer than a majority of the
Trustees then in office have been elected by the shareholders. Trustees
elected at the Annual Meeting of shareholders on April 26, 1995, will continue
in office until the next Annual Meeting unless they die, resign or are
removed, either for cause or without cause, at any meeting of shareholders by
an affirmative vote of a majority of the outstanding shares entitled to vote
for the election of Trustees. The Trustees may elect their own successors and
appoint Trustees to fill any vacancy only if, after filling the vacancy, at
least two-thirds of the Trustees then in office have been elected by the
shareholders. If at any time less than a majority of Trustees in office have
been elected by the shareholders, the Trustees must call a special
shareholders' meeting promptly for the purpose of electing the Board of
Trustees.
 
  The Trustees shall promptly call a meeting of shareholders for the purpose
of voting upon the question of removal of any Trustee or all of the Trustees
when requested in writing to do so by holders of 10% or more of the
outstanding shares. Whenever ten or more shareholders who have been such for
at least six months and who hold in the aggregate either shares having a net
asset value of at least $25,000 or at least 1% of the outstanding shares,
whichever is less, apply to the Trustees in writing stating that they wish to
communicate with other shareholders with a view to obtaining signatures to a
request for a shareholders' meeting, for consideration of the removal of any
or all of the Trustees and accompanied by the material which they wish to
transmit, the Trustees will within five business days after receipt either
afford to such applicants access to the Fund's shareholder list or inform such
applicants as to the approximate number of shareholders of record, and the
approximate cost of mailing the material. If the Trustees elect the latter,
the Trustees, upon written request of
 
                                      25
<PAGE>
 
such applicants, accompanied by the material to be mailed and the reasonable
expenses of mailing, shall promptly mail such material to all shareholders of
record, unless within five business days the Trustees shall mail to such
applicants and file with the Securities and Exchange Commission, together with
a copy of the material to be mailed, a written statement signed by at least a
majority of the Trustees to the effect that in their opinion either such
material is misleading or in violation of applicable law and specifying the
basis of such opinion.
 
  In addition to transferring assets to the Fund through Variable Life Account
U and Variable Annuity Account U, JHVLICO also provided additional capital for
the Fund by purchasing through Variable Life Account U $350,000 worth of
shares each of the Large Cap Growth and Managed Portfolios and through
Variable Life Account V $500,000 worth of shares each of the Real Estate
Equity, International Equities, Short-Term U.S. Government, and Special
Opportunities Portfolios. JHVLICO may withdraw such additional investment at
some time. However, before withdrawing any part of their interests in any
Portfolio, John Hancock or JHVLICO will consider any possible adverse impact
the withdrawal might have on that Portfolio.
 
  If the contractholders show minimal interest in any Portfolio, the Fund's
Board of Trustees, by majority vote, may eliminate the Portfolio or substitute
shares of another investment company. Any such action by the Board would be
subject to compliance with any requirements for governmental approvals or
exemptions or for shareholder approval. The contractholders of such Portfolios
will be notified in writing of the Fund's intention to eliminate the Portfolio
and given 30 days to transfer amounts from such Portfolio to other Portfolios
without incurring a transaction fee. Amounts not transferred or withdrawn will
automatically be transferred, at the discretion of the Fund's management.
 
                                 VOTING RIGHTS
 
  All shares of the Fund of whatever class are entitled to one vote, and the
votes of all classes are cast on an aggregate basis, except on matters where
the interests of the Portfolios differ. Where the interests of the Portfolios
differ, the voting is on a Portfolio-by-Portfolio basis. Approval or
disapproval by the shareholders in one Portfolio on such a matter would not
generally be a prerequisite of approval or disapproval by shareholders in
another Portfolio; and shareholders in a Portfolio not affected by a matter
generally would not be entitled to vote on that matter. Examples of matters
which would require a Portfolio-by-Portfolio vote are changes in the
fundamental investment policy of a particular Portfolio and approval of
investment management or sub-investment management agreements.
 
                       REDEMPTION AND PRICING OF SHARES
 
  Redemptions are normally made in cash, but the Fund reserves the right, at
its discretion, to make full or partial payment by assignment to the
appropriate Separate Account of portfolio securities at their value used in
determining the redemption price. In such cases, the Separate Account would
incur brokerage costs should it wish to liquidate these portfolio securities.
The right to redeem shares or to receive payment with respect to any
redemption of shares of any Portfolio may only be suspended (a) for any period
during which trading on the New York Stock Exchange is restricted or such
Exchange is closed (other than customary weekend and holiday closings), (b)
for any period during which an emergency exists as a result of which disposal
of portfolio securities or determination of the net asset value of that
Portfolio is not reasonably practicable, or (c) for such other periods as the
Securities and Exchange Commission may by order permit for the protection of
shareholders of the Portfolio.
 
                                      26
<PAGE>
 
  The value of the Money Market Portfolio's securities is stated at amortized
cost, which generally approximates market value. This involves valuing a
security at its cost and thereafter assuming a constant amortization to
maturity of any discount or premium, regardless of the impact of fluctuating
interest rates. While this method provides certainty in valuation, it may
result in periods during which the value of an instrument, as determined by
amortized cost, is higher or lower than the price the Portfolio would receive
upon the sale of the instrument.
 
  The valuation of the Money Market Portfolio's securities based upon their
amortized cost is subject to the Portfolio's adherence to certain procedures
and conditions. The portfolio manager will purchase U.S. dollar-denominated
securities with remaining maturities of 397 days or less and will maintain a
dollar-weighted average portfolio maturity of no more than 90 days. The
portfolio manager will invest only in securities that are judged to present
minimal credit risk and that satisfy the quality and diversification
requirements of applicable rules and regulations of the SEC.
 
  The Board of Trustees has established procedures designed to stabilize the
Money Market Portfolio's price per share, as computed for the purpose of sales
and redemptions, at $10.00. There can be no assurance, however, that the
Portfolio will at all times be able to maintain a constant $10.00 net asset
value per share. Such procedures include review of the Portfolio's holdings at
such intervals as is deemed appropriate to determine whether the Portfolio's
net asset value, calculated by using available market quotations, deviates
from $10.00 per share and, if so, whether such deviation may result in
material dilution, or is otherwise unfair to existing shareholders. In the
event that it is determined that such a deviation exists, the Board of
Trustees will take such corrective action as it regards as necessary and
appropriate. Such action may include selling portfolio instruments prior to
maturity to realize capital gains or losses or to shorten average portfolio
maturity, withholding dividends, or establishing a net asset value per share
by using available market quotations.
 
                                     TAXES
   
  In order for the Fund to qualify for Federal income tax treatment as a
regulated investment company, at least 90 percent of each Portfolio's gross
income for each taxable year must be derived from qualifying income, i.e.,
dividends, interest, income derived from loans of securities, and gains from
the sale of securities.     
 
  To avoid taxation of capital gains, the Fund will distribute to the Separate
Accounts each Portfolio's net capital gains at least annually and net
investment income at least monthly. A Portfolio's net investment income from
the time of the immediately preceding dividend declaration consists of
interest accrued or discount earned during such period (including both
original issue and market discount) on that Portfolio's securities, less
amortization of premium and the actual or estimated expenses of the Portfolio
applicable to that dividend period.
 
  Each Portfolio must also be adequately diversified in its investments and
maintain its status as a regulated investment company ("RIC") in order that
the variable life insurance policies and annuity contracts funded through the
Separate Accounts retain their character as life insurance or an annuity and
the related tax benefits for annuity and insurance contract holders. John
Hancock will monitor continued compliance with the adequate diversification
requirements set forth in regulations issued by the Treasury Department. The
diversification requirements are briefly summarized below.
 
  For a Portfolio to qualify as a regulated investment company ("RIC"), at the
end of each fiscal quarter of the Portfolio's taxable year, (i) at least 50%
of the market value of the Portfolio's assets must be represented by
 
                                      27
<PAGE>
 
cash and cash items, U.S. Government securities, securities of other RICs, and
other securities, with such other securities limited, in respect of any one
issuer, to an amount that does not exceed 10% of the voting securities of such
issuer of 5% of the value of the Portfolio's total assets; and (ii) not more
than 25% of the value of its assets may be invested in the securities (other
than U.S. Government securities and securities of other RICs) of any one
issuer or two or more issuers which the Portfolio controls and which are
engaged in the same, similar or related trades or businesses. Should a
Portfolio, for any reason, fail to qualify for tax treatment as a RIC,
investment company, or otherwise incur any tax liability, the investment
performance of the Separate Accounts could be adversely affected, to the
detriment of the contractholders.
 
  In addition, Treasury Department regulations require that no more than 55%
of the total value of the assets of each Portfolio be represented by any one
investment, no more than 70% by any two investments, no more than 80% by three
investments and no more than 90% by four investments. Generally, for purposes
of the regulations, all securities of the same issuer are treated as one
investment. In the context of U.S. Government securities (including any
security that is issued, guaranteed or insured by the United States or an
instrumentality of the United States), each U.S. Government agency or
instrumentality is treated as a separate issuer.

                        CALCULATION OF PERFORMANCE DATA
 
  The Money Market Portfolio may advertise investment performance figures,
including its current yield and its effective yield. (See the following
section on "Calculation of Yield Quotation of the Money Market Portfolio" for
a complete description.)
 
YIELD AND TOTAL RETURN INFORMATION FOR ALL PORTFOLIOS OTHER THAN THE MONEY
MARKET PORTFOLIO
 
  The non-money market Portfolios of the Fund may also advertise investment
performance figures, including yield. Each such Portfolio's yield is based
upon a stated 30-day period and is computed by dividing the net investment
income per share earned during the period by the maximum offering price per
share on the last day of the period, according to the following formula:
                      
                   YIELD = 2[([(a-b)/(cd)] + 1)/6/ -1]     
 
  Where:
      a= dividends and interest earned during the period
 
      b= expenses accrued for the period (net of reimbursements, if any)
 
      c= the average daily number of shares outstanding during the period
         that were entitled to receive dividends
 
      d= the maximum offering price (which is the net asset value) per
         share on the last day of the period.
   
  The following table shows the current yield for each of the Portfolios for
the 30-day period ended December 31, 1997:

  Each of the Portfolios may advertise its total return. Total return
quotations will be based upon a stated period and will be computed by finding
the average annual compounded rate of return over the stated period that
 
                                      29

would equate an initial amount invested to the ending redeemable value of the
investment (assuming reinvestment of all distributions), according to the
following formula:
                                
                             P (1 + T)/n/ = ERV     
 
  Where:
      P=   a hypothetical initial payment of $1,000
 
      T=   average annual total return
 
      n=   number of years
 
      ERV= ending redeemable value at the end of the stated period of a
           hypothetical $1,000 payment made at the beginning of the stated
           period
 
  The average annual total return for each of the Portfolios for the periods
ending December 31, 1996 is set forth in the Appendix to the prospectus.
 
CALCULATION OF YIELD QUOTATIONS OF THE MONEY MARKET PORTFOLIO
 
  The Money Market Portfolio's yield is its current investment income
expressed in annualized terms. The current yield is based on a specified
seven-calendar-day period. It is computed by (1) determining the net change
(exclusive of capital changes) in the value of a hypothetical pre-existing
account having a balance of one share at the beginning of the period, (2)
dividing the net change in account value by the value of the account at the
beginning of the base period to get the base period return, then (3)
multiplying the base period return by 52.15 (365 divided by 7). The resulting
yield figure is carried to the nearest hundredth of one percent.
 
  The calculations include the value of additional shares purchased with any
dividends paid on the original share and the value of dividends declared on
both the original share and any such additional shares. The capital changes
excluded from the calculation are realized capital gains and losses from the
sale of securities and unrealized appreciation and depreciation.
 
  Compound (effective) yield for the Portfolio will be computed by dividing
the seven-day annualized yield as defined above by 365, adding 1 to the
quotient, raising the sum to the 365th power, and subtracting 1 from the
result.
   
  For the seven-day period ending December 31, 1997, the Money Market
Portfolio's current yield was   %; its effective yield was   %.     
 
  The Portfolio's yield will fluctuate depending upon market conditions, the
type, quality, and maturity of the instruments in the Portfolio, and its
expenses. Current yield information should not be deemed comparable to bank
deposits or other investments which pay a fixed return or which calculate
yields on a different basis.
 
CHARGES UNDER VARIABLE LIFE INSURANCE AND VARIABLE ANNUITY POLICIES
 
  Yield and total return quotations do not reflect any charges imposed on any
Separate Account or otherwise imposed pursuant to JHVLICO's and John Hancock's
variable life insurance and variable annuity policies. Therefore, the yield or
total return of any Portfolio is not comparable to that of a publicly
available fund. Yield or total return quotations should not be considered
representative of the Portfolio's yield or total return in any future period.

ITEM 27. INDEMNIFICATION
 
  Reference is made to Article VI of the Registrant's By-Laws (Exhibit 2 to
Post-Effective Amendment No. 3 to this Registration Statement dated April,
1988), which provides that the Trust shall indemnify or advance any expenses
to the trustees, shareholders, officers, or employees of the Trust to the
extent set forth in the Declaration of Trust.
 
                                     II-4
<PAGE>
 
  Sections 6.3 through 6.17 of the Declaration of Trust (Exhibit I to Post-
Effective Amendment No. 3 to this Registration Statement dated April, 1988),
relate to the indemnification of trustees, shareholders, officers and
employees and are hereby incorporated by references. It is provided that the
Registrant shall indemnify any Trustee made a party to any proceeding by
reason of service in that capacity if the Trustee (a) acted in good faith and
(b) reasonably believed, (1) in the case of conduct in the Trustee's official
capacity with the Trust, that the conduct was in the best interest of the
Trust and (2) in all other cases, that the conduct was at least not opposed to
the best interests of the Trust, and (c) in the case of any criminal
proceeding, the Trust shall indemnify the Trustee if the Trustee acted in good
faith and had no reasonable cause to believe that the conduct was unlawful.
Indemnification may not be made by the Trust unless authorized in each case by
a determination by the Board of Trustees or by special legal counsel or by the
shareholders. Neither indemnification nor advancement of expenses may be made
if the Trustee or officer has incurred liability by reason of willful
misfeasance, bad faith, gross negligence, or reckless disregard of duties
involved in the conduct of his office ("Disabling Conduct"). The means for
determining whether indemnification shall be made shall be (1) a final
decision on the merits by a court or other body before whom the proceeding was
brought that the person to be indemnified was not liable by reason of
Disabling Conduct or (2) in the absence of such a decision, a reasonable
determination, based upon a review of the facts, that such person was not
liable by reason of Disabling Conduct. Such latter determination may be made
either (a) by the vote of a majority of a quorum of Trustees who are neither
"interested persons" of the Trust (as defined in the 1940 Act, as amended) nor
parties to the proceeding or (b) by an independent legal counsel in a written
opinion. The advancement of legal expenses may not occur unless the Trustee or
officer agrees to repay the advance (unless it is ultimately determined that
he is entitled to indemnification) and at least one of three conditions is
satisfied: (1) he provides security for his agreement to repay, (2) the
Registrant is insured against loss by reason of lawful advances, or (3) a
majority of a quorum the Trustees who are not interested persons and are not
parties to the proceedings, or independent counsel in a written opinion,
determine that there is reason to believe that the Trustee or officer will be
found entitled to indemnification.
     
  Similar types of provisions dealing with the indemnification of the
Registrant's officers and directors is included in several exhibits attached

  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to trustees, officers, and controlling persons of the
Registrant pursuant to the Registrant's By-Laws or otherwise, the Registrant
has been advised that, in the opinion of the Securities and Exchange
Commission (the "Commission"), such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a trustee, officer or
controlling person of the Registrant in the successful defense of any action,
suit, or proceeding) is asserted by such trustee, officer, or controlling
person in connection with the securities being registered, then the Registrant
will,

unless in the opinion of its counsel the matter has been settled by a
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

John Hancock Variable Series Trust I
John Hancock Place
P.O. Box 111
Boston, MA 02117


Trustees:
    
     This opinion is given in connection with the filing by John Hancock
Variable Series Trust I, a Massachusetts business trust, (the "Fund") of its
Post-Effective Amendment No. 17 to its Registration Statement on Form N-1A (File
No. 33-2081; the "Registration Statement") under the Securities Act of 1933 and
the Investment Company Act of 1940, relating to an indefinite amount of its
shares of beneficial interest, which includes twenty-four separate series (i.e.,
the Managed, Growth & Income, Equity Index, Large Cap Value, Large Cap Growth,
Mid Cap Value, Mid Cap Growth, Special Opportunities, Real Estate Equity,
Small/Mid Cap CORE Equity, Small Cap Value, Small Cap Growth, Global Equity,
International Balanced, International Equity Index, International Equities,
International Opportunities, Emerging Markets Equity, Short-Term U.S.
Government, Diversified Bond Index, Sovereign Bond, Strategic Bond, High Yield
Bond, and Money Market Portfolios). The Fund's shares of beneficial interest,
including the twenty-four series of shares, are hereinafter referred to as the
"shares".    
    
     I have examined the Fund's Declaration of Trust, its By-Laws, the
Registration Statement of its predecessor as originally filed on December 11,
1985, subsequent post-effective amendments and this Post-Effective Amendment No.
17, and such other records, certificates, documents and statutes that I have
deemed relevant in order to render the opinion expressed herein.     

     Based on such examination, I am of the opinion that:

     1.  The Fund is a business trust duly organized, validly existing and in 
         good standing under the laws of the Commonwealth of Massachusetts.

<PAGE>
 
                                      -2-


     2.  The shares offered for sale by the Fund, when issued in the manner
         contemplated by this Post-Effective Amendment to its Registration
         Statement, will be legally issued, fully-paid and non-assessable.


     I consent to the use of this opinion as Exhibit 10 to the Post-Effective 
Amendment to the Registration Statement and to the use of my name under the 
caption "Legal Matters" in the Statement of Additional Information incorporated 
by reference into the Prospectus comprising a part of the Registration 
Statement.

                                      Very truly yours,
