PROSPECTUS SUMMARY

THE FUND                The Fund is organized as a Trust, commonly known as a Massachusetts business
                        trust, and is an open-end diversified management investment company. The Fund is
                        comprised of fifteen separate Portfolios: the MONEY MARKET PORTFOLIO, the QUALITY
                        INCOME PLUS PORTFOLIO, the HIGH YIELD PORTFOLIO, the UTILITIES PORTFOLIO, the
                        INCOME BUILDER PORTFOLIO, the DIVIDEND GROWTH PORTFOLIO, the CAPITAL GROWTH
                        PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO,
                        the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the EQUITY
                        PORTFOLIO, the S&P 500 INDEX PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS"
                        PORTFOLIO and the STRATEGIST PORTFOLIO (see pages 13 through 41). The Trustees of
                        the Fund may establish additional Portfolios at any time. To the extent that
                        shares are sold to the Companies in order to fund the benefits under Contracts,
                        the structure of the Fund permits Contract Owners, within the limitations
                        described in the Contracts, to allocate the investments underlying the Contracts
                        in response to or in anticipation of changes in market or economic conditions. See
                        the accompanying Prospectus for either the Variable Annuity Contracts or the
                        Variable Life Contracts for a description of the relationship between increases or
                        decreases in the net asset value of Fund shares and any distributions on such
                        shares, and benefits provided under a Contract.
                        Each Portfolio is managed for investment purposes as if it were a separate fund
                        issuing a separate class of shares of beneficial interest, with $.01 par value.
                        The assets of each Portfolio are segregated, so that an interest in the Fund is
                        limited to the assets of the Portfolio in which shares are held and shareholders,
                        such as the Companies, are each entitled to a pro rata share of all dividends and
                        distributions arising from the net investment income and capital gains, if any, of
                        such Portfolio (see pages 44 and 46).
- ----------------------------------------------------------------------------------------------------------
INVESTMENT              Each Portfolio has distinct investment objectives and policies, and is subject to
OBJECTIVES,             various investment restrictions, some of which apply to all the Portfolios. The
POLICIES,               MONEY MARKET PORTFOLIO seeks high current income, preservation of capital and
RESTRICTIONS            liquidity by investing in short-term money market instruments (see pages 13-14).
AND RISKS               The QUALITY INCOME PLUS PORTFOLIO seeks, as its primary objective, to earn a high
                        level of current income and, as a secondary objective, capital appreciation, but
                        only when consistent with its primary objective, by investing primarily in U.S.
                        Government securities and higher-rated fixed-income securities and by writing
                        covered options on such securities (see pages 14-15). The HIGH YIELD PORTFOLIO
                        seeks, as a primary objective, to earn a high level of current income and, as a
                        secondary objective, seeks capital appreciation, but only when consistent with its
                        primary objective, by investing primarily in lower-rated fixed-income securities,
                        which are commonly known as junk bonds (see pages 16-17). The UTILITIES PORTFOLIO
                        seeks to provide current income and long-term growth of income and capital by
                        investing primarily in equity and fixed-income securities of companies engaged in
                        the public utilities industry (see pages 17-18). The INCOME BUILDER PORTFOLIO
                        seeks, as its primary objective, reasonable income and, as its secondary
                        objective, growth of capital, by investing primarily in income-producing equity
                        securities (see pages 18-20). The DIVIDEND GROWTH PORTFOLIO seeks to provide
                        reasonable current income and long-term growth of income and capital by investing
                        primarily in common stock of companies with a record of paying dividends and the
                        potential for increasing dividends (see pages 20-21). The CAPITAL GROWTH PORTFOLIO
                        seeks long-term capital growth by investing primarily in common stocks (see page
                        21). The GLOBAL DIVIDEND GROWTH PORTFOLIO seeks to provide reasonable current
                        income and long-term growth of income and capital by investing primarily in common
                        stock of companies, issued by issuers worldwide, with a record of paying dividends
                        and the potential for increasing dividends (see page 22). The EUROPEAN GROWTH
                        PORTFOLIO seeks to maximize the capital

                        appreciation of its investments by investing primarily in securities issued by
                        issuers located in Europe (see pages 22-23). The PACIFIC GROWTH PORTFOLIO seeks to
                        maximize the capital appreciation of its investments by investing primarily in
                        securities issued by issuers located in Asia, Australia and New Zealand (see pages
                        23-25). The CAPITAL APPRECIATION PORTFOLIO seeks long-term capital appreciation by
                        investing primarily in the common stocks of U.S. companies that offer the
                        potential for either superior earnings growth and/or appear to be undervalued (see
                        pages 25-26). The EQUITY PORTFOLIO seeks, as a primary objective, capital growth
                        through investments in common stock and, as a secondary objective, income but only
                        when consistent with its primary objective (see pages 26-27). The S&P 500 INDEX
                        PORTFOLIO seeks to provide investment results that, before expenses, correspond to
                        the total return (I.E., the combination of capital changes and income) of the

                        500 Index") by investing, under normal circumstances, at least 80% of the value of
                        its total assets in common stocks included in the S&P 500 Index in approximately
                        the same weightings as the Index (see pages 27-28). The COMPETITIVE EDGE "BEST
                        IDEAS" PORTFOLIO seeks long-term capital growth by investing, under normal
                        circumstances, at least 80% of its net assets in the common stock of U.S. and
                        non-U.S. companies included in the "Best Ideas" subgroup of "Global Investing: The
                        Competitive Edge," a research compilation assembled and maintained by Morgan
                        Stanley Dean Witter Equity Research, and such Supplemental Securities chosen by
                        the Investment Manager (see pages 28-30). The STRATEGIST PORTFOLIO seeks a high
                        total investment return through a fully managed investment policy utilizing equity
                        securities, investment grade fixed-income securities and money market securities,
                        and the writing of covered options on such securities and the collateralized sale
                        of stock index options (see pages 30-31).

                        Although the MONEY MARKET PORTFOLIO will attempt to maintain a constant net asset
                        value per share of $1.00, there can be no assurance that the $1.00 net asset value
                        can be maintained. The net asset value of shares of each Portfolio other than the
                        MONEY MARKET PORTFOLIO will fluctuate with changes in the market value of its
                        portfolio holdings. The market value of the Portfolios' securities will increase
                        or decrease due to a variety of economic, market and political factors which
                        cannot be predicted. A decline in prevailing interest rates generally increases
                        the value of fixed-income securities, while an increase in rates generally reduces
                        the value of those securities. Dividends payable by each Portfolio will vary in
                        relation to the amounts of dividends and/or interest paid by its securities
                        holdings.

                        options and may enter into transactions involving interest rate futures contracts
                        and bond index futures contracts and options thereon as a means of hedging against
                        changes in the market value of the Portfolio's investments. The UTILITIES

                        PORTFOLIO may also hedge against such changes by entering into transactions
                        involving stock index futures contracts and options thereon, and (except for the
                        EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH PORTFOLIO) options on stock
                        indexes. The S&P 500 INDEX PORTFOLIO may enter into stock index futures contracts
                        to simulate full investment in the S&P 500 Index while retaining a cash balance
                        for portfolio management purposes, to facilitate trading, to reduce transaction
                        costs or to seek higher investment returns when a futures contract is priced more
                        attractively than stocks comprising the S&P 500 Index. Each Portfolio may invest,
                        to a different extent, in foreign securities. Foreign securities markets pose
                        different and generally greater risks than those customarily associated with
                        domestic securities and markets including fluctuations in foreign currency
                        exchange rates, foreign tax rates and foreign securities exchange controls.

                        HIGH YIELD PORTFOLIO, the UTILITIES PORTFOLIO, the INCOME BUILDER PORTFOLIO, the
                        DIVIDEND GROWTH PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND

                        the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the STRATEGIST PORTFOLIO involve
                        more risk than investment in the MONEY MARKET PORTFOLIO. The high yield, high risk
                        fixed-income securities in which the HIGH YIELD PORTFOLIO will invest, and the
                        INCOME BUILDER PORTFOLIO may invest, are subject to greater risk of loss of income
                        and principal than higher rated, lower yielding fixed-income securities. The
                        prices of high yield, high risk securities have been found to be less sensitive to
                        changes in prevailing interest rates than higher rated investments, but are likely
                        to be more sensitive to adverse economic changes or individual corporate
                        developments. Investors in these Portfolios should carefully consider the relative
                        risks of investing in high yield securities and should be cognizant of the fact
                        that such securities are not generally meant for short-term investing (see the
                        discussion of lower-rated securities beginning on page 34). Investors in the
                        CAPITAL APPRECIATION PORTFOLIO should be aware that the Portfolio is intended for
                        long-term investors who can accept the risks involved in seeking long-term
                        appreciation through the investment primarily in securities of companies that
                        offer the potential for either superior earnings growth and/or appear to be
                        undervalued (see the discussion of such securities beginning on page 25). In
                        selecting investments for the CAPITAL APPRECIATION PORTFOLIO, the Investment
                        Manager has no general criteria as to a company's asset size, earnings or industry
                        type. Investors in the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO should be aware
                        that there can be no assurance that the securities contained in the Competitive
                        Edge "Best Ideas" List, which currently consists of only 40 companies, will
                        perform as anticipated. Past performance of securities and issuers included in the
                        Competitive Edge "Best Ideas" List cannot be used to predict future results of the
                        Portfolio, which is actively managed by the Investment Manager and the results of
                        which are expected to vary from the performance of the Competitive Edge "Best
                        Ideas" List.
                        Contract Owners are also directed to the discussion of options and futures
                        transactions (page 37), repurchase agreements (page 35), foreign securities (page
                        31), forward foreign currency exchange contracts (page 32), public utilities
                        securities (page 18), convertible securities (page 34), warrants (page 36), zero

                        concerning risks associated with such securities and management techniques. The
                        Fund is a single diversified investment company, consisting of fifteen Portfolios,
                        and each Portfolio itself is diversified. Diversification does not eliminate
                        investment risk. Contract Owners should review the investment objectives and
                        policies of the Portfolios carefully and consider their ability to assume the
                        risks involved in allocating the investments underlying the Contracts (see pages
                        13-41).

                        Company ("Northbrook") for allocation to certain separate accounts established to
                        fund the benefits under certain flexible premium deferred variable annuity
                        contracts and certain flexible premium variable life insurance contracts issued by

                        Life Insurance Company ("Paragon") for allocation to a separate account
                        established to fund the benefits under certain flexible premium variable life
                        insurance contracts it issues in connection with an employer-sponsored insurance
                        program offered only to certain employees of Morgan Stanley Dean Witter & Co., the
                        parent company of the Fund's Investment Manager. The separate accounts are
                        sometimes referred to individually as an "Account" and collectively as the
                        "Accounts." The variable annuity contracts issued by Northbrook, Allstate New York
                        and Glenbrook are sometimes referred to as the "Variable Annuity Contracts," the
                        variable life insurance contracts issued by Northbrook, Glenbrook and Paragon are
                        sometimes referred to as the "Variable Life Contracts," and the Variable Annuity
                        Contracts and the Variable Life Contracts are sometimes referred to as the
                        "Contracts." Northbrook, Allstate New York, Glenbrook and Paragon are sometimes
                        referred to as the "Companies." Accordingly, the interest of the Contract Owner
                        with respect to the Fund is subject to the terms of the Contract and is described
                        in the accompanying Prospectus for the Variable Annuity Contracts or the Variable
                        Life Contracts, which should be reviewed carefully by a person considering the
                        purchase of a Contract. The accompanying Prospectus for the Variable Annuity
                        Contracts or the Variable Life Contracts describes the relationship between
                        increases or decreases in the net asset value of Fund shares and any distributions
                        on such shares, and the benefits provided under a Contract. The rights of the
                        Companies as shareholders of the Fund should be distinguished from the rights

                        of a Contract Owner which are described in the Contract. In the future, shares may
                        be allocated to certain other separate accounts or sold to affiliated and/or
                        non-affiliated entities of the Companies in connection with variable annuity
                        contracts or variable life insurance contracts. As long as shares of the Fund are
                        sold only to the Companies, the terms "shareholder" or "shareholders" in this
                        Prospectus shall refer to the Companies. It is conceivable that in the future it
                        may become disadvantageous for both variable life and variable annuity contract
                        separate accounts to invest in the same underlying fund (see pages 43 and 46).

about the performance of the Portfolios of the Fund is contained in the Fund's
Annual Report to Shareholders, which may be obtained without charge upon request
to the Fund. See the discussion under the caption "Charges and Other Deductions"
in the accompanying prospectus for either the Variable Annuity Contracts or the
Variable Life Contracts for a description of charges which may be imposed on the
Contracts by the applicable Account. Any such charges are not reflected in the
financial highlights below. Inclusion of any such charges would reduce the total
return figures for all periods shown. The S&P 500 INDEX PORTFOLIO and the
COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO did not commence operations before
December 31, 1997.

THE FUND AND ITS MANAGEMENT
- ----------------------------------------------------------
 
Dean Witter Variable Investment Series (the "Fund") is an open-end diversified
management investment company. The Fund is a Trust of the type commonly known as
a "Massachusetts business trust" and was organized under the laws of The
Commonwealth of Massachusetts on February 25, 1983.
 
Dean Witter InterCapital Inc. ("InterCapital" or the "Investment Manager"),
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Investment Manager. The Investment Manager, which was incorporated in July,
1992, is a wholly-owned subsidiary of Morgan Stanley Dean Witter & Co. ("MSDW"),
a preeminent global financial services firm that maintains leading market
positions in each of its three primary businesses--securities, asset management
and credit services.
 
InterCapital and its wholly-owned subsidiary, Dean Witter Services Company Inc.,
serve in various investment management, advisory, management and administrative
capacities to 101 investment companies, 28 of which are listed on the New York
Stock Exchange, with combined total assets of approximately $109.5 billion at
March 31, 1998. The Investment Manager also manages portfolios of pension plans,
other institutions and individuals which aggregated approximately $4.1 billion
at such date.
 
The Fund has retained the Investment Manager to provide administrative services,
manage its business affairs and manage the investment of the Fund's assets,
including the placing of orders for the purchase and sale of portfolio
securities. InterCapital has retained Dean Witter Services Company Inc. to
perform the aforementioned administrative services for the Fund.
 
With regard to the EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH PORTFOLIO,
under Sub-Advisory Agreements between Morgan Grenfell Investment Services
Limited (the "Sub-Adviser") and the Investment Manager, the Sub-Adviser provides
the EUROPEAN GROWTH PORTFOLIO with investment advice and portfolio management
relating to that Portfolio's investments in securities issued by issuers located
in Europe and in other countries located elsewhere around the world, and
provides the PACIFIC GROWTH PORTFOLIO with investment advice and portfolio
management relating to that Portfolio's investments in securities issued by
issuers located in Asia, Australia and New Zealand and in countries located
elsewhere around the world, in each case subject to the overall supervision of
the Investment Manager. The Sub-Adviser, whose address is 20 Finsbury Circus,
London, England, currently manages assets in excess of $18 billion primarily for
U.S. corporate and public employee benefit plans, endowments, investment
companies and foundations. The Sub-Adviser is an indirect subsidiary of Deutsche
Bank AG, the largest commercial bank in Germany.
 
The Fund's Trustees review the various services provided by or under the
direction of the Investment Manager (and, for the EUROPEAN GROWTH PORTFOLIO and
the PACIFIC GROWTH PORTFOLIO, by the Sub-Adviser) to ensure that the Fund's
general investment policies and programs are being properly carried out and that
administrative services are being provided to the Fund in a satisfactory manner.
 
As full compensation for the services and facilities furnished to the Fund and
expenses of the Fund assumed by the Investment Manager, the Fund currently pays
the Investment Manager monthly compensation calculated daily by applying the
annual rate of 0.40% to the net assets of the S&P 500 INDEX PORTFOLIO, by
applying the annual rate of 0.50% to the net assets of the HIGH YIELD PORTFOLIO
up to $500 million and the annual rate of 0.425% to the net assets of that
Portfolio exceeding $500 million, by applying the annual rate of 0.50% to the
net assets of the QUALITY INCOME PLUS PORTFOLIO up to $500 million and the
annual rate of 0.45% to the net assets of that Portfolio exceeding $500 million,
by applying the annual rate of 0.50% to the net assets of the EQUITY PORTFOLIO
up to $1 billion and 0.475% to the net assets of that Portfolio exceeding $1
billion, by applying the annual rate of 0.50% to the net assets of each of the
MONEY MARKET PORTFOLIO and the STRATEGIST PORTFOLIO, by applying the annual rate
of 0.625% to the net assets of the DIVIDEND GROWTH PORTFOLIO up to $500 million,
the annual rate of 0.50% to the next $500 million, the annual rate of 0.475% to
the next $1 billion, and the annual rate of 0.45% to the net assets of that
Portfolio exceeding $2 billion, by applying the annual rate of 0.65% to the net
assets of the UTILITIES PORTFOLIO up to $500 million and the annual rate of
0.55% to the net assets of that Portfolio exceeding $500 million, by applying
the annual rate of 0.65% to the net assets of each of the CAPITAL GROWTH
PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO, by applying the
annual rate of 0.75% to the net assets of each of the INCOME BUILDER PORTFOLIO,
the GLOBAL DIVIDEND GROWTH PORTFOLIO and the CAPITAL APPRECIATION PORTFOLIO, by
applying the annual rate of 1.0% to the net assets of the EUROPEAN GROWTH
PORTFOLIO up to $500 million and the annual rate of 0.95% to the net assets of
that Portfolio exceeding $500 million, and by applying the annual rate of 1.0%
to the net assets of the PACIFIC GROWTH PORTFOLIO, in each case determined as of
the close of each business day. As compensation for its services provided to the
EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH PORTFOLIO pursuant to the Sub-
Advisory Agreements in respect of those Portfolios, the Investment Manager pays
the Sub-Adviser monthly compensation equal to 40% of its monthly compensation in
respect of each of the EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH
PORTFOLIO.
 
For the year ended December 31, 1997, the Fund accrued total compensation to the
Investment Manager amounting to 0.50% of the average daily net assets of each of
the MONEY MARKET PORTFOLIO, the QUALITY INCOME PLUS PORTFOLIO, the HIGH YIELD
PORTFOLIO, the EQUITY PORTFOLIO and the STRATEGIST PORTFOLIO, 0.53% of the
average daily net assets of the DIVIDEND GROWTH PORTFOLIO, 0.65% of the average
daily net assets of each of the UTILITIES PORTFOLIO and the CAPITAL GROWTH
PORTFOLIO, 0.75% of the average daily net assets of the GLOBAL DIVIDEND GROWTH
PORTFOLIO, and 1.0% of the average
 
                                       12

daily net assets of each of the EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH
PORTFOLIO. The total expenses of the MONEY MARKET PORTFOLIO amounted to 0.52% of
its average daily net assets, the total expenses of the QUALITY INCOME PLUS
PORTFOLIO amounted to 0.53% of the average daily net assets, the total expenses
of the HIGH YIELD PORTFOLIO amounted to 0.53% of its average daily net assets,
the total expenses of the EQUITY PORTFOLIO amounted to 0.52% of its average
daily net assets, the total expenses of the STRATEGIST PORTFOLIO amounted to
0.52% of its average daily net assets, the total expenses of the DIVIDEND GROWTH
PORTFOLIO amounted to 0.54% of its average daily net assets, the total expenses
of the UTILITIES PORTFOLIO amounted to 0.67% of its average daily net assets,
the total expenses of the CAPITAL GROWTH PORTFOLIO amounted to 0.71% of its
average daily net assets, the total expenses of the GLOBAL DIVIDEND GROWTH
PORTFOLIO amounted to 0.84% of its average daily net assets, the total expenses
of the EUROPEAN GROWTH PORTFOLIO amounted to 1.12% of its average daily net
assets, and the total expenses of the PACIFIC GROWTH PORTFOLIO amounted to 1.44%
of its average daily net assets.
 
The INCOME BUILDER PORTFOLIO and the CAPITAL APPRECIATION PORTFOLIO commenced
operations on January 21, 1997. The Investment Manager has undertaken to assume
all expenses of each of these Portfolios (except for any brokerage fees) and to
waive the compensation provided for each of these Portfolios in its Management
Agreement with the Fund until such time as the pertinent Portfolio has $50
million of net assets or until July 31, 1998, whichever occurs first. The INCOME
BUILDER PORTFOLIO attained $50 million of net assets on December 3, 1997.
 
The S&P 500 INDEX PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO did
not commence operations prior to the date of this Prospectus. The Investment
Manager has undertaken to assume all expenses of each of these Portfolios
(except for any brokerage fees) and to waive the compensation provided for each
of these Portfolios in its Management Agreement with the Fund until such time as
the pertinent Portfolio has $50 million of net assets or until six months from
the date of the Portfolio's commencement of operations, whichever occurs first.
Thereafter, the Investment Manager has agreed to assume all expenses of the S&P
500 INDEX PORTFOLIO (except for any brokerage fees) and to waive the
compensation provided for that Portfolio in its Management Agreement with the
Fund to the extent that such expenses and compensation on an annualized basis
exceed 0.50% of the daily net assets of the S&P 500 INDEX PORTFOLIO.
 
INVESTMENT OBJECTIVES AND POLICIES
- ----------------------------------------------------------
 
THE MONEY MARKET PORTFOLIO
 
The investment objectives of the MONEY MARKET PORTFOLIO are high current income,
preservation of capital and liquidity. The MONEY MARKET PORTFOLIO seeks to
achieve those objectives by investing in the following money market instruments:
 
U.S. GOVERNMENT SECURITIES. Obligations issued or guaranteed as to principal and
interest by the United States or its agencies (such as the Export-Import Bank of
the United States, Federal Housing Administration, and Government National
Mortgage Association) or its instrumentalities (such as the Federal Home Loan
Bank, Federal Intermediate Credit Banks and Federal Land Bank), including
Treasury bills, notes and bonds;
 
BANK OBLIGATIONS. Obligations (including certificates of deposit and bankers'
acceptances) of banks subject to regulation by the U.S. Government and having
total assets of $1 billion or more, and instruments secured by such obligations,
not including obligations of foreign branches of domestic banks except to the
extent below;
 
EURODOLLAR CERTIFICATES OF DEPOSIT. Eurodollar certificates of deposit issued by
foreign branches of domestic banks having total assets of $1 billion or more
(see the discussion of foreign securities under "General Portfolio Techniques"
below);
 
OBLIGATIONS OF SAVINGS INSTITUTIONS. Certificates of deposit of savings banks
and savings and loan associations, having total assets of $1 billion or more;
 
FULLY INSURED CERTIFICATES OF DEPOSIT. Certificates of deposit of banks and
savings institutions, having total assets of less than $1 billion, if the
principal amount of the obligation is insured by the Federal Deposit Insurance
Corporation or the Federal Savings and Loan Insurance Corporation, limited to
$100,000 principal amount per certificate and to 10% or less of the Portfolio's
total assets in all such obligations and in all illiquid assets, in the
aggregate;
 
COMMERCIAL PAPER. Commercial paper rated within the two highest grades by
Standard & Poor's Corporation ("S&P") or the highest grade by Moody's Investors
Service, Inc. ("Moody's"), or, if not rated, issued by a company having an
outstanding debt issue rated at least AA by S&P or Aa by Moody's;
 
CORPORATE OBLIGATIONS. Corporate obligations, rated at least A by S&P or
Moody's, maturing in one year or less.
 
See the Appendix for an explanation of S&P and Moody's ratings.
 
VARIABLE RATE OBLIGATIONS. The interest rates payable on certain securities in
which the MONEY MARKET PORTFOLIO may invest are not fixed and may fluctuate
based upon changes in market rates. Obligations of this type are called
"variable rate" obligations. The interest rate payable on a variable rate
obligation is adjusted
 
                                       13
<PAGE>
either at predesignated periodic intervals or whenever there is a change in the
market rate of interest on which the interest rate payable is based.
 
The MONEY MARKET PORTFOLIO may enter into repurchase agreements, may lend its
portfolio securities and purchase securities on a when-issued or delayed
delivery basis, in each case in accordance with the description of those
techniques (and subject to the risks) set forth under "General Portfolio
Techniques" below and in the Statement of Additional Information.
 
The investment objectives and policies stated above may not be changed without
the approval of the shareholders of the MONEY MARKET PORTFOLIO. The MONEY MARKET
PORTFOLIO may not invest in securities other than the types of securities listed
above and is subject to other specific investment restrictions as detailed under
"Investment Restrictions" below and in the Statement of Additional Information.
 
Although the MONEY MARKET PORTFOLIO will not generally be managed with a policy
of active short-term trading, it may dispose of any portfolio security prior to
its maturity if, on the basis of a revised credit evaluation of the issuer or
other circumstances or considerations, the Investment Manager believes such
disposition advisable.
 
The MONEY MARKET PORTFOLIO is expected to have a high portfolio turnover due to
the short maturities of securities purchased, but this should not affect income
or net asset value as brokerage commissions are not normally charged on the
purchase or sale of money market instruments.
 
The MONEY MARKET PORTFOLIO will attempt to balance its objectives of high
income, capital preservation and liquidity by investing in securities of varying
maturities and risks. The MONEY MARKET PORTFOLIO will not, however, invest in
securities that mature in more than one year from the date of purchase (see
"Determination of Net Asset Value"). The amounts invested in obligations of
various maturities of one year or less will depend on management's evaluation of
the risks involved. Longer-term issues, while generally paying higher interest
rates, are subject to greater fluctuations in value resulting from general
changes in interest rates than shorter-term issues. Thus, when rates on new debt
securities increase, the value of outstanding securities may decline, and vice
versa. Such changes may also occur, but to a lesser degree, with short-term
issues. These changes, if realized, may cause fluctuations in the amount of
daily dividends and, in extreme cases, could cause the net asset value per share
to decline (see "Determination of Net Asset Value"). Longer-term issues also
increase the risk that the issuer may be unable to pay an installment of
interest or principal at maturity. Also, in the event of unusually large
redemption demands, such securities may have to be sold at a loss prior to
maturity, or the MONEY MARKET PORTFOLIO might have to borrow money and incur
interest expenses. Either occurrence would adversely impact the amount of daily
dividend and could result in a decline in net asset value per share or the
redemption by the MONEY MARKET PORTFOLIO of shares held in a shareholder's
account. The MONEY MARKET PORTFOLIO will attempt to minimize these risks by
investing in longer-term securities when it appears to management that interest
rates on such securities are not likely to increase substantially during the
period of expected holding, and then only in securities of high quality which
are readily marketable. However, there can be no assurance that the MONEY MARKET
PORTFOLIO will be successful in achieving this or its other objectives.
 
THE QUALITY INCOME PLUS PORTFOLIO
 
The primary investment objective of the QUALITY INCOME PLUS PORTFOLIO is to earn
a high level of current income, by investing primarily in U.S. Government
securities and other fixed-income securities. As a secondary objective, the
QUALITY INCOME PLUS PORTFOLIO will seek capital appreciation but only when
consistent with its primary objective. There is no assurance that the objectives
will be achieved. The objectives of the QUALITY INCOME PLUS PORTFOLIO are
fundamental policies of the Portfolio and, as such, may not be changed without
the approval of the shareholders of the QUALITY INCOME PLUS PORTFOLIO.
 
The QUALITY INCOME PLUS PORTFOLIO has also adopted the following investment
policies which are not fundamental policies and may be changed by the Trustees
of the Fund without shareholder approval.
 
In seeking to achieve its objectives, the QUALITY INCOME PLUS PORTFOLIO will
normally invest at least 65% of its net assets in a combination of U.S.
Government securities and debt securities (including straight debt securities
and debt securities convertible into common stock) and "Yankee government
bonds," which are U.S. dollar denominated debt securities issued by foreign
governments or their respective instrumentalities or agencies which securities
are either registered under the Securities Act of 1933 or eligible for resale
pursuant to Rule 144A under that Act and pay both principal and interest in U.S.
dollars, which have a rating at the time of purchase within the three highest
grades as determined by Moody's Investors Service, Inc. ("Moody's") (Aaa, Aa or
A) or Standard & Poor's Corporation ("S&P") (AAA, AA or A) or which, if not
rated, are deemed to be of comparable quality by the Fund's Trustees, with a
maximum of 20% of the Portfolio's net assets in "Yankee government bonds."
However, any security which subsequently receives a rating as low as Baa(3) by
Moody's or BBB- by S&P (the lowest investment grade ratings) will be eliminated
from the portfolio at such time as the Investment Manager determines that it is
practicable to sell the security without undue market or tax consequences to the
QUALITY INCOME PLUS PORTFOLIO. A description of corporate bond ratings is
contained in the Appendix. See "General Portfolio Techniques" below for a
discussion of convertible securities and foreign securities. Securities which
may be purchased include zero coupon securities (see "General Portfolio
Techniques" below).
 
Generally, as prevailing interest rates rise, the value of the U.S. Government
and other debt securities held by the QUALITY INCOME
 
                                       14
<PAGE>
PLUS PORTFOLIO, and concomitantly, the net asset value of the Portfolio's
shares, will fall. Such securities with longer maturities generally tend to
produce higher yields and are subject to greater market fluctuation as a result
of changes in interest rates than debt securities with shorter maturities. The
Portfolio is not limited as to the maturities of the U.S. Government and other
debt securities in which it may invest.
 
U.S. Government securities include:
 
    (1) U.S. Treasury bills (maturities of one year or less), U.S. Treasury
notes (maturities of one to ten years) and U.S. Treasury bonds (generally
maturities of greater than ten years), all of which are direct obligations of
the U.S. Government and, as such, are backed by the "full faith and credit" of
the United States.
 
    (2) Securities issued by agencies and instrumentalities of the U.S.
Government which are backed by the full faith and credit of the United States.
Among the agencies and instrumentalities issuing such obligations are the
Federal Housing Administration, the Government National Mortgage Association
("GNMA"), the Department of Housing and Urban Development, the Export-Import
Bank, the Farmers Home Administration, the General Services Administration, the
Maritime Administration and the Small Business Administration. The maturities of
such obligations range from three months to thirty years.
 
    (3) Securities issued by agencies and instrumentalities which are not backed
by the full faith and credit of the United States, but whose issuing agency or
instrumentality has the right to borrow, to meet its obligations, from an
existing line of credit with the U.S. Treasury. Among the agencies and
instrumentalities issuing such obligations are the Tennessee Valley Authority,
the Federal National Mortgage Association ("FNMA"), the Federal Home Loan
Mortgage Corporation ("FHLMC") and the U.S. Postal Service.
 
    (4) Securities issued by agencies and instrumentalities which are not backed
by the full faith and credit of the United States, but which are backed by the
credit of the issuing agency or instrumentality. Among the agencies and
instrumentalities issuing such obligations are the Federal Farm Credit System
and the Federal Home Loan Banks.
 
Certain of the U.S. Government securities in which the QUALITY INCOME PLUS
PORTFOLIO may invest; E.G., certificates issued by GNMA, FNMA and FHLMC, are
"mortgage-backed securities," which evidence an interest in a specific pool of
mortgages. These certificates are, in most cases, "pass-through" instruments,
wherein the issuing agency guarantees the timely payment of principal and
interest on mortgages underlying the certificates, whether or not such amounts
are collected by the issuer on the underlying mortgages.
 
The average life of such certificates varies with the maturities of the
underlying mortgage instruments, which may be up to thirty years. This average
life is likely to be substantially shorter than the original maturity of the
mortgage pools underlying the certificates, as a pool's duration may be
shortened by unscheduled or early payments of principal on the underlying
mortgages. The occurrence of mortgage prepayments is affected by factors
including the prevailing level of interest rates, general economic conditions,
the location and age of the mortgage and other social and demographic
conditions. For example, during periods of declining interest rates, mortgage
prepayments can be expected to accelerate. As prepayment rates vary widely, it
is not possible to accurately predict the average life of a particular pool. The
net asset value of shares of the QUALITY INCOME PLUS PORTFOLIO and the
Portfolio's ability to achieve its investment objectives may be adversely
affected by mortgage prepayments.
 
While the QUALITY INCOME PLUS PORTFOLIO will invest primarily in U.S. Government
and other debt securities, it may invest up to 35% of its portfolio (including
options on debt instruments, options on futures contracts and futures contracts)
in money market instruments, including commercial paper, certificates of
deposit, bankers' acceptances and other obligations of domestic banks or
domestic branches of foreign banks, or foreign branches of domestic banks, in
each case having total assets of at least $500 million, and obligations issued
or guaranteed by the United States Government, and, within this portion of the
portfolio, up to 15% of its net assets in "Yankee corporate bonds," which are
U.S. dollar denominated debt securities issued by foreign corporations which
securities are either registered under the Securities Act of 1933 or eligible
for resale pursuant to Rule 144A under that Act and pay both principal and
interest in U.S. dollars, and which have a rating at the time of purchase within
the three highest grades as determined by Moody's or S&P or which, if not rated,
are deemed to be of comparable quality by the Fund's Trustees (any security
which subsequently receives a rating as low as Baa(3) by Moody's or BBB- by S&P
will be eliminated from the portfolio at such time as the Investment Manager
determines that it is practicable to sell the security without undue market or
tax consequences to the QUALITY INCOME PLUS PORTFOLIO) (see "General Portfolio
Techniques" below and in the Statement of Additional Information). Moreover, and
notwithstanding any of the above, the QUALITY INCOME PLUS PORTFOLIO may invest
in money market instruments without limitation when market conditions dictate a
"defensive" investment strategy.
 
The QUALITY INCOME PLUS PORTFOLIO may enter into repurchase agreements, lend its
portfolio securities, purchase securities on a when-issued or delayed delivery
basis or a "when, as and if issued" basis, and purchase or sell securities on a
forward commitment basis, in each case in accordance with the description of
those techniques (and subject to the risks) set forth under "General Portfolio
Techniques" below and in the Statement of Additional Information.
 
    BORROWING.  The QUALITY INCOME PLUS PORTFOLIO may borrow money, but only
from a bank and in an amount up to 25% of the Portfolio's gross assets taken at
the lower of market value or cost, not including the amount borrowed. When the
Portfolio borrows it will be because it seeks additional income by leveraging
its investments through purchasing securities with the borrowed
 
                                       15
<PAGE>
funds. The QUALITY INCOME PLUS PORTFOLIO will be required to maintain an asset
coverage (including the proceeds of borrowings) of at least 300% of such
borrowings in accordance with the provisions of the Investment Company Act of
1940, as amended (the "Act").
 
THE HIGH YIELD PORTFOLIO
 
The primary investment objective of the HIGH YIELD PORTFOLIO is to earn a high
level of current income by investing in a professionally managed diversified
portfolio consisting principally of fixed-income securities, which may include
both non-convertible and convertible debt securities and preferred stocks. As a
secondary objective, the HIGH YIELD PORTFOLIO will seek capital appreciation,
but only when consistent with its primary objective. Capital appreciation may
result, for example, from an improvement in the credit standing of an issuer
whose securities are held in the portfolio of the HIGH YIELD PORTFOLIO or from a
general decline in interest rates, or a combination of both. Conversely, capital
depreciation may result, for example, from a lowered credit standing or a
general rise in interest rates, or a combination of both. There is no assurance
that the objectives will be achieved.
 
The objectives of the HIGH YIELD PORTFOLIO may not be changed without the
approval of the shareholders of the HIGH YIELD PORTFOLIO. The following policies
may be changed by the Trustees of the Fund without shareholder approval:
 
The higher yields sought by the HIGH YIELD PORTFOLIO are generally obtainable
from securities rated in the lower categories by recognized rating services. The
HIGH YIELD PORTFOLIO seeks high current income by investing principally in
fixed-income securities, as described above, which are rated Baa or lower by
Moody's Investors Service, Inc. ("Moody's"), or BBB or lower by Standard &
Poor's Corporation ("S&P"). Fixed-income securities rated Baa by Moody's or BBB
by S&P have speculative characteristics greater than those of more highly-rated
bonds, while fixed-income securities rated Ba or BB or lower by Moody's and S&P,
respectively, are considered to be speculative investments. Furthermore, the
HIGH YIELD PORTFOLIO does not have any minimum quality rating standard for its
investments. As such, the High Yield Portfolio may invest in securities rated as
low as Caa, Ca or C by Moody's or CCC, CC, C or CI by S&P. Fixed-income
securities rated Caa or Ca by Moody's may already be in default on payment of
interest or principal, while bonds rated C by Moody's, their lowest bond rating,
can be regarded as having extremely poor prospects of ever attaining any real
investment standing. Bonds rated CI by S&P, their lowest bond rating, are no
longer making interest payments. For a further discussion of the characteristics
and risks associated with high yield securities, and for a discussion of
convertible securities, see "General Portfolio Techniques" below. A description
of corporate bond ratings is contained in the Appendix.
 
Non-rated securities will also be considered for investment by the HIGH YIELD
PORTFOLIO when the Investment Manager believes that the financial condition of
the issuers of such securities, or the protection afforded by the terms of the
securities themselves, makes them appropriate investments for the HIGH YIELD
PORTFOLIO.
 
All fixed-income securities are subject to two types of risks: the credit risk
and the interest rate risk. The credit risk relates to the ability of the issuer
to meet interest or principal payments or both as they come due. The interest
rate risk refers to the fact that there are fluctuations in net asset value of
any portfolio of fixed-income securities resulting from the inverse relationship
between price and yield of fixed-income securities; that is, when the general
level of interest rates rises, the prices of outstanding fixed-income securities
generally decline, and when interest rates fall, prices generally rise.
 
The ratings of fixed-income securities by Moody's and S&P are a generally
accepted barometer of credit risk. However, as the creditworthiness of issuers
of lower-rated fixed-income securities is more problematical than that of the
issuers of higher-rated fixed-income securities, the achievements of the HIGH
YIELD PORTFOLIO's investment objectives will be more dependent upon the
Investment Manager's own credit analysis than would be the case with a mutual
fund investing primarily in higher quality bonds. The Investment Manager will
utilize a security's credit rating as simply one indication of an issuer's
creditworthiness and will principally rely upon its own analysis of any security
currently held by the HIGH YIELD PORTFOLIO or potentially purchasable by the
Portfolio.
 
In determining which securities to purchase or hold for the portfolio of the
HIGH YIELD PORTFOLIO and in seeking to reduce the credit and interest rate
risks, the Investment Manager will rely on information from various sources,
including: the rating of the security; research, analysis and appraisals of
brokers and dealers, including Dean Witter Reynolds Inc.; the views of the
Trustees of the Fund and others regarding economic developments and interest
rate trends; and the Investment Manager's own analysis of factors it deems
relevant. The extent to which the Investment Manager is successful in reducing
depreciation or losses arising from either interest rate or credit risks depends
in part on the Investment Manager's portfolio management skills and judgment in
evaluating the factors affecting the value of securities. No assurance can be
given regarding the degree of success that will be achieved.
 
Consistent with its primary investment objective, the HIGH YIELD PORTFOLIO
anticipates that, under normal conditions, at least 65% of the value of its
total assets will be invested in the lower-rated and non-rated fixed-income
securities (including zero coupon securities) previously described. However,
when the yields derived from such securities and those derived from higher-rated
issues are relatively narrow, the HIGH YIELD PORTFOLIO may invest in the
higher-rated issues since they may provide similar yields with somewhat less
risk.
 
Pending investment of proceeds of sale of shares of the HIGH YIELD PORTFOLIO or
of its portfolio securities or at other times when market conditions dictate a
more "defensive" investment strategy, the HIGH YIELD PORTFOLIO may invest
without limit in money market instruments, including commercial paper of
corporations organized under the laws of any state or political subdivision of
the United States, certificates of deposit, bankers' acceptances and other
obligations of domestic banks or domestic branches of foreign banks, or foreign
branches of domestic banks, in each
 
                                       16
<PAGE>
case having total assets of at least $500 million, and obligations issued or
guaranteed by the United States Government, or foreign governments or their
respective instrumentalities or agencies. The yield on these securities will
generally tend to be lower than the yield on other securities that can be
purchased by the HIGH YIELD PORTFOLIO.
 
The HIGH YIELD PORTFOLIO may enter into repurchase agreements, invest in foreign
securities (including American Depository Receipts, European Depository Receipts
or other similar securities convertible into securities of foreign issuers),
lend its portfolio securities, purchase securities on a when-issued or delayed
delivery basis, or a "when, as and if issued" basis, and purchase or sell
securities on a forward commitment basis, in each case in accordance with the
description of those investments and techniques (and subject to the risks) set
forth under "General Portfolio Techniques" below and in the Statement of
Additional Information. The HIGH YIELD PORTFOLIO may purchase unit offerings
(where corporate debt securities are offered as a unit with convertible
securities, preferred or common stocks, warrants, or any combination thereof)
(see the discussion of warrants under "General Portfolio Techniques" below).
 
PUBLIC UTILITIES. The HIGH YIELD PORTFOLIO's investments in public utilities, if
any, may be subject to certain risks (see the description of the risks
associated with investment in public utilities set forth below under "The
Utilities Portfolio").
 
SPECIAL INVESTMENT CONSIDERATIONS. Because of the special nature of the HIGH
YIELD PORTFOLIO's investment in high yield securities, commonly known as "junk
bonds," the Investment Manager must take account of certain special
considerations in assessing the risks associated with such investments.
Investors should carefully consider the risks of investing in high yield
securities (see "General Portfolio Techniques" below and in the Statement of
Additional Information for a discussion of the risks of investments in high
yield securities).
 
During the fiscal year ended December 31, 1997, the monthly dollar weighted
average ratings of the debt obligations held by the HIGH YIELD PORTFOLIO,
expressed as a percentage of the Portfolio's total investments in debt
obligations, were as follows:

THE UTILITIES PORTFOLIO
 
The investment objective of the UTILITIES PORTFOLIO is to provide current income
and long-term growth of income and capital, by investing primarily in equity and
fixed-income securities of companies engaged in the public utilities industry.
The objective of the UTILITIES PORTFOLIO may not be changed without the approval
of the shareholders of the UTILITIES PORTFOLIO. The term "public utilities
industry" consists of companies engaged in the manufacture, production,
generation, transmission, sale and distribution of gas and electric energy, as
well as companies engaged in the communications field, including telephone,
telegraph, satellite, microwave and other companies providing communication
facilities for the public, but excluding public broadcasting companies. For
purposes of the UTILITIES PORTFOLIO, a company will be considered to be in the
public utilities industry if, during the most recent twelve month period, at
least 50% of the company's gross revenues, on a consolidated basis, is derived
from the public utilities industry. The following investment policies may be
changed by the Trustees of the Fund without shareholder approval:
 
In seeking to achieve its objective, the UTILITIES PORTFOLIO will normally
invest at least 65% of its total assets in securities of companies in the public
utilities industry. The Investment Manager believes the UTILITIES PORTFOLIO's
investment policies are suited to benefit from certain characteristics and
historical performance of the securities of public utility companies. Many of
these companies have historically set a pattern of paying regular dividends and
increasing their common stock dividends over time, and the average common stock
dividend yield of utilities historically has substantially exceeded that of
industrial stocks. The Investment Manager believes that these factors may not
only provide current income but also generally tend to moderate risk and thus
may enhance the opportunity for appreciation of securities owned by the
UTILITIES PORTFOLIO, although the potential for capital appreciation has
historically been lower for many utility stocks compared with most industrial
stocks. There can be no assurance that the historical investment performance of
the public utilities industry will be indicative of future events and
performance. There can be no assurance that the investment objective of the
UTILITIES PORTFOLIO will be achieved.
 
The UTILITIES PORTFOLIO will invest in both equity securities (common stocks and
securities convertible into common stock) and fixed income securities (bonds and
preferred stock) in the public utilities industry. The UTILITIES PORTFOLIO does
not have any set policies to concentrate within any particular segment of the
utilities industry. The UTILITIES PORTFOLIO will shift its asset allocation
without restriction between types of utilities and between equity and
fixed-income securities based upon the Investment Manager's determination of how
to achieve the UTILITIES PORTFOLIO's investment objective in light of prevailing
market, economic and financial conditions. For example, at a particular time the
Investment Manager may choose to allocate up to 100% of the UTILITIES
PORTFOLIO's assets in a particular type of security (for
 
                                       17
<PAGE>
example, equity securities) or in a specific utility industry segment (for
example, electric utilities). See "General Portfolio Techniques" below for a
discussion of convertible securities.
 
Criteria to be utilized by the Investment Manager in the selection of equity
securities include the following screens: earnings and dividend growth; book
value; dividend discount; and price/ earnings relationships. In addition, the
Investment Manager makes continuing assessments of management, the prevailing
regulatory framework and industry trends. The Investment Manager may also
utilize computer-based equity selection models in connection with stock
allocation in the equity portion of the portfolio. In keeping with the UTILITIES
PORTFOLIO's objective, if in the opinion of the Investment Manager favorable
conditions for capital growth of equity securities are not prevalent at a
particular time, the UTILITIES PORTFOLIO may allocate its assets predominantly
or exclusively in debt securities with the aim of obtaining current income as
well as preserving capital and thus benefiting long term growth of capital.
 
The UTILITIES PORTFOLIO may purchase equity securities sold on the New York,
American and other stock exchanges and in the over-the-counter market.
Fixed-income securities in which the UTILITIES PORTFOLIO may invest are debt
securities and preferred stocks, which are rated at the time of purchase Baa or
better by Moody's Investors Service, Inc. or BBB or better by Standard & Poor's
Corporation or which, if unrated, are deemed to be of comparable quality by the
Fund's Trustees (see "General Portfolio Techniques" below for a discussion of
the characteristics and risks of investments in fixed-income securities rated
Baa or BBB). Under normal circumstances the average weighted maturity of the
debt portion of the portfolio is expected to be in excess of seven years. A
description of corporate bond ratings is contained in the Appendix.
 
While the UTILITIES PORTFOLIO will invest primarily in the securities of public
utility companies, under ordinary circumstances it may invest up to 35% of its
total assets in U.S. Government securities (securities issued or guaranteed as
to principal and interest by the United States or its agencies and
instrumentalities), money market instruments, repurchase agreements, options and
futures (see "General Portfolio Techniques" below and in the Statement of
Additional Information). U.S. Government securities are described above and in
the Statement of Additional Information under the caption "The Quality Income
Plus Portfolio." The UTILITIES PORTFOLIO may acquire warrants attached to other
securities purchased by the Portfolio (see "General Portfolio Techniques"
below).
 
There may be periods during which, in the opinion of the Investment Manager,
market conditions warrant reduction of some or all of the UTILITIES PORTFOLIO's
securities holdings. During such periods, the UTILITIES PORTFOLIO may adopt a
temporary "defensive" posture in which greater than 35% of its total assets are
invested in cash or money market instruments which would be eligible investments
for the Fund's MONEY MARKET PORTFOLIO (as set forth above under "The Money
Market Portfolio").
 
The UTILITIES PORTFOLIO may enter into repurchase agreements, invest in foreign
securities (including American Depository Receipts, European Depository Receipts
or other similar securities convertible into securities of foreign issuers),
invest in zero coupon securities, invest in real estate investment trusts, lend
its portfolio securities, purchase securities on a when-issued or delayed
delivery basis or a "when, as and if issued" basis, and purchase or sell
securities on a forward commitment basis, in each case in accordance with the
description of those investments and techniques (and subject to the risks) set
forth under "General Portfolio Techniques" below and in the Statement of
Additional Information.
 
PUBLIC UTILITIES INDUSTRY. The public utilities industry as a whole has certain
characteristics and risks particular to that industry. Unlike industrial
companies, the rates which utility companies may charge their customers
generally are subject to review and limitation by governmental regulatory
commissions. Although rate changes of a utility usually fluctuate in approximate
correlation with financing costs, due to political and regulatory factors rate
changes ordinarily occur only following a delay after the changes in financing
costs. This factor will tend to favorably affect a utility company's earnings
and dividends in times of decreasing costs, but conversely will tend to
adversely affect earnings and dividends when costs are rising. In addition, the
value of public utility debt securities (and, to a lesser extent, equity
securities) tends to have an inverse relationship to the movement of interest
rates.
 
Among the risks affecting the utilities industry are the following: risks of
increases in fuel and other operating costs; the high cost of borrowing to
finance capital construction during inflationary periods; restrictions on
operations and increased costs and delays associated with compliance with
environmental and nuclear safety regulations; the difficulties involved in
obtaining natural gas for resale or fuel for generating electricity at
reasonable prices; the risks in connection with the construction and operation
of nuclear power plants; the effects of energy conservation and the effects of
regulatory changes, such as the possible adverse effects of profits on recent
increased competition within the telecommunications, electric and natural gas
industries and the uncertainties resulting from companies within these
industries diversifying into new domestic and international businesses, as well
as from agreements by many such companies linking future rate increases to
inflation or other factors not directly related to the actual operating profits
of the enterprise.
 
THE INCOME BUILDER PORTFOLIO
 
The primary investment objective of the INCOME BUILDER PORTFOLIO is to seek
reasonable income. Growth of capital is a secondary objective. There can be no
assurance that the objectives will be achieved. The objectives of the INCOME
BUILDER PORTFOLIO may not
 
                                       18
<PAGE>
be changed without the approval of the shareholders of the INCOME BUILDER
PORTFOLIO. The following policies may be changed by the Trustees of the Fund
without shareholder approval:
 
The INCOME BUILDER PORTFOLIO seeks to achieve its objectives by investing, under
normal market conditions, at least 65% of its total assets in income-producing
equity securities, including common stock, preferred stock and convertible
securities. Up to 35% of the Portfolio's assets may be invested in fixed-income
securities or common stocks that do not pay a regular dividend but are expected
to contribute to the Portfolio's ability to meet its investment objectives.
 
The INCOME BUILDER PORTFOLIO will invest, under normal market conditions,
primarily in common stocks of large-cap companies which have a record of paying
dividends and, in the opinion of the Investment Manager, have the potential for
maintaining dividends, in preferred stock and in securities convertible into
common stocks of small and mid-cap companies. See "General Portfolio Techniques"
below for a discussion of convertible securities, including a discussion of
"enhanced," "synthetic" and "exchangeable" convertible securities in which the
INCOME BUILDER PORTFOLIO may invest. The Investment Manager intends to use a
value-oriented investment style in the selection of securities for the portfolio
of the INCOME BUILDER PORTFOLIO.
 
The INCOME BUILDER PORTFOLIO also may invest up to 20% of its total assets in
fixed-income securities rated below investment grade. Securities below
investment grade are the equivalent of high yield, high risk bonds (commonly
known as "junk bonds"). Investment grade is generally considered to be debt
securities rated BBB or higher by Standard & Poor's Corporation ("S&P") or Baa
or higher by Moody's Investors Service, Inc. ("Moody's"). See "General Portfolio
Techniques" below for a discussion of investments in securities rated BBB by S&P
or Baa by Moody's. Fixed-income securities rated BBB by S&P or Baa by Moody's,
which generally are regarded to have an adequate capacity to pay interest and
repay principal, have speculative characteristics. However, the INCOME BUILDER
PORTFOLIO will not invest in fixed-income securities that are rated lower than B
by S&P or Moody's or, if not rated, are determined to be of comparable quality
by the Investment Manager. The INCOME BUILDER PORTFOLIO will not invest in
fixed-income securities that are in default in payment of principal or interest.
The 20% limitation on securities rated below investment grade in which the
INCOME BUILDER PORTFOLIO may invest does not include securities convertible into
common stock. A description of fixed-income security ratings is contained in the
Appendix. See "General Portfolio Techniques" below for a discussion of the risks
of investments in lower rated, high yield securities.
 
A portion of the INCOME BUILDER PORTFOLIO's assets may be invested in investment
grade fixed income (fixed-rate and adjustable rate) securities such as corporate
notes and bonds and obligations issued or guaranteed by the U.S. Government, its
agencies and instrumentalities. U.S. Government securities are described above
and in the Statement of Additional Information under "The Quality Income Plus
Portfolio."
 
The non-governmental debt securities in which the INCOME BUILDER PORTFOLIO will
invest will include: (a) corporate debt securities, including bonds, notes and
commercial paper, rated in the four highest categories by a nationally
recognized statistical rating organization ("NRSRO") including Moody's Investors
Service, Inc., Standard & Poor's Corporation, Duff and Phelps, Inc. and Fitch
Investors Service, Inc.; and (b) bank obligations, including CDs, banker's
acceptances and time deposits, issued by banks with a long-term CD rating in one
of the four highest categories by a NRSRO. Investments in securities rated
within the four highest rating categories by a NRSRO are considered "investment
grade." However, such securities rated within the fourth highest rating category
by a NRSRO have speculative characteristics and, therefore, changes in economic
conditions or other circumstances are more likely to weaken their capacity to
make principal and interest payments than would be the case with investments in
securities with higher credit ratings. Where a fixed-income security is not
rated by a NRSRO (as may be the case with a foreign security) the Investment
Manager will make a determination of its creditworthiness and may deem it to be
investment grade. A description of fixed-income security ratings is contained in
the Appendix.
 
Payments of interest and principal on U.S. Government securities are guaranteed
by the U.S. Government; however, neither the value nor the yield of corporate
notes and bonds and U.S. Government securities which may be invested in by the
INCOME BUILDER PORTFOLIO are guaranteed by the U.S. Government. Values and yield
of corporate and government bonds will fluctuate with changes in prevailing
interest rates and other factors. Generally, as prevailing interest rates rise,
the value of corporate notes and bonds and government bonds held by the
Portfolio will fall. Securities with longer maturities generally tend to produce
higher yields and are subject to greater market fluctuation as a result of
changes in interest rates than debt securities with shorter maturities. The
INCOME BUILDER PORTFOLIO is not limited as to the maturities of the debt
securities in which it may invest.
 
The Investment Manager intends to follow a "bottom-up" approach in the selection
of convertible securities for the INCOME BUILDER PORTFOLIO. Beginning with a
universe of about 500 companies, the Investment Manager will narrow the focus to
small and mid-cap companies and review the issues to determine if the
convertible is trading with the underlying equity security. The yield of the
underlying equity security will be evaluated and company fundamentals will be
studied to evaluate cash flow, risk/reward balance, valuation and the prospects
for growth. The Investment Manager intends to select convertible securities
that, in its judgment, are issued by companies with sound management practices
and that represent good value.
 
Money market instruments in which the INCOME BUILDER PORTFOLIO may invest
include securities issued or guaranteed by the U.S.
 
                                       19
<PAGE>
Government, its agencies and instrumentalities (Treasury bills, notes and bonds,
including zero coupon securities); bank obligations; Eurodollar certificates of
deposit; obligations of savings institutions; fully insured certificates of
deposit; and commercial paper rated within the four highest grades by Moody's or
S&P or, if not rated, issued by a company having an outstanding debt issue rated
at least AA by S&P or Aa by Moody's. Such securities may be used to invest
uncommitted cash balances. There may be periods during which, in the opinion of
the Investment Manager, market conditions warrant reduction of some or all of
the Portfolio's securities holdings. During such periods, the INCOME BUILDER
PORTFOLIO may adopt a temporary "defensive" posture in which up to 100% of its
total assets is invested in money market instruments or cash.
 
The INCOME BUILDER PORTFOLIO may enter into repurchase agreements, invest in
foreign securities (including American Depository Receipts, European Depository
Receipts or other similar securities convertible into securities of foreign
issuers), invest in warrants, zero coupon securities and real estate investment
trusts, lend its portfolio securities, purchase securities which are issued in
private placements or are otherwise not readily marketable, purchase securities
on a when-issued or delayed delivery basis or a "when, as and if issued" basis,
and purchase or sell securities on a forward commitment basis, in each case in
accordance with the description of these investments and techniques (and subject
to the risks) set forth under "General Portfolio Techniques" below and in the
Statement of Additional Information.
 
The INCOME BUILDER PORTFOLIO is authorized to engage in transactions involving
options and futures contracts that would be eligible for use by the STRATEGIST
PORTFOLIO, as described under "Options and Futures Transactions" under "General
Portfolio Techniques" below and in the Statement of Additional Information. The
INCOME BUILDER PORTFOLIO does not, however, presently intend to engage in such
options and futures transactions and will not do so unless and until the Fund's
prospectus has been revised to reflect this.
 
SPECIAL INVESTMENT CONSIDERATIONS. Because of the special nature of the INCOME
BUILDER PORTFOLIO's investments in high yield securities, commonly known as
"junk bonds," the Investment Manager must take account of certain special
considerations in assessing the risks associated with such investments.
Investors should carefully consider the risks of investing in high yield
securities (see "General Portfolio Techniques" below and in the Statement of
Additional Information for a discussion of the risks of investments in high
yield securities).
 
During the fiscal year ended December 31, 1997, the monthly dollar weighted
average ratings of the debt obligations held by the INCOME BUILDER PORTFOLIO,
expressed as a percentage of the Portfolio's total investments in debt
obligations, were as follows:

THE DIVIDEND GROWTH PORTFOLIO
 
The investment objective of the DIVIDEND GROWTH PORTFOLIO is to provide
reasonable current income and long-term growth of income and capital. There is
no assurance that the objective will be achieved. The DIVIDEND GROWTH PORTFOLIO
seeks to achieve its investment objective primarily through investments in
common stock of companies with a record of paying dividends and the potential
for increasing dividends. Net asset value of the DIVIDEND GROWTH PORTFOLIO's
shares will fluctuate with changes in market values of portfolio securities. The
DIVIDEND GROWTH PORTFOLIO will attempt to avoid speculative securities or those
with speculative characteristics.
 
The investment objective of the DIVIDEND GROWTH PORTFOLIO may not be changed
without the approval of the shareholders of the DIVIDEND GROWTH PORTFOLIO. The
following policies may be changed by the Trustees of the Fund without
shareholder approval:
 
    (1) Up to 30% of the value of the DIVIDEND GROWTH PORTFOLIO's total assets
may be invested in: (a) convertible debt securities, convertible preferred
securities, warrants (see "General Portfolio Techniques" below), U.S. Government
securities (securities issued or guaranteed as to principal and interest by the
United States or its agencies and instrumentalities), corporate debt securities
which are rated at the time of purchase Baa or better by Moody's Investors
Service, Inc. or BBB or better by Standard & Poor's Corporation or which, if
unrated, are deemed to be of comparable quality by the Fund's Trustees (see
"General Portfolio Techniques" below for a discussion of the characteristics and
risks of investments in fixed-income securities rated Baa or BBB) and/or money
market instruments which would be eligible investments for the Fund's MONEY
MARKET PORTFOLIO (as set forth above under "The Money Market Portfolio") when,
in the opinion of the Investment Manager, the projected total return on such
securities is equal to or greater than the expected total return on equity
securities or when such holdings might be expected to reduce the volatility of
the portfolio (for purposes of
 
                                       20
<PAGE>
this provision, the term "total return" means the difference between the cost of
a security and the aggregate of its market value and dividends received); or (b)
in money market instruments under any one or more of the following
circumstances: (i) pending investment of proceeds of sale of the DIVIDEND GROWTH
PORTFOLIO's shares or of portfolio securities; (ii) pending settlement of
purchases of portfolio securities; or (iii) to maintain liquidity for the
purpose of meeting anticipated redemptions.
 
    (2) Notwithstanding any of the foregoing limitations, the DIVIDEND GROWTH
PORTFOLIO may invest more than 30% of the value of its total assets in money
market instruments to maintain, temporarily, a "defensive" posture when, in the
opinion of the Investment Manager, it is advisable to do so because of economic
or market conditions.
 
The DIVIDEND GROWTH PORTFOLIO may enter into repurchase agreements, invest in
American Depository Receipts, invest in zero coupon securities, invest in real
estate investment trusts, lend its portfolio securities, purchase securities on
a when-issued or delayed delivery basis or a "when, as and if issued" basis, and
purchase or sell securities on a forward commitment basis, in each case in
accordance with the description of those investments and techniques (and subject
to the risks) set forth under "General Portfolio Techniques" below and in the
Statement of Additional Information.
 
The DIVIDEND GROWTH PORTFOLIO is authorized to engage in transactions involving
options and futures contracts which would be eligible for use by the STRATEGIST
PORTFOLIO. These transactions are described under "Options and Futures
Transactions" under "General Portfolio Techniques" below and in the Statement of
Additional Information. The DIVIDEND GROWTH PORTFOLIO does not, however,
presently intend to engage in such options and futures transactions and will not
do so unless and until the Fund's prospectus were revised to reflect this.
 
THE CAPITAL GROWTH PORTFOLIO
 
The investment objective of the CAPITAL GROWTH PORTFOLIO is long-term capital
growth. There is no assurance that the objective will be achieved. The
investment objective of the CAPITAL GROWTH PORTFOLIO may not be changed without
the approval of the shareholders of the CAPITAL GROWTH PORTFOLIO. The following
policies may be changed by the Board of Trustees without shareholder approval:
 
The CAPITAL GROWTH PORTFOLIO seeks to achieve its investment objective by
investing, under normal circumstances, at least 65% of its total assets in
common stocks. As part of its management of the Portfolio, the Investment
Manager will utilize a screening process designed to find companies which have
demonstrated a history of consistent growth in earnings and revenues for the
past several years. Additionally, screened companies will have solid future
earnings growth characteristics and attractive valuations. Companies meeting
these requirements will be potential candidates for investment by the CAPITAL
GROWTH PORTFOLIO. Subject to the Portfolio's investment objective, the
Investment Manager, without notice, may modify the foregoing screening process
and/ or may utilize additional or different screening processes in connection
with the investment of the Portfolio's assets. Dividend income will not be a
consideration in the selection of stocks for purchase.
 
Although the CAPITAL GROWTH PORTFOLIO will invest primarily in common stocks,
the Portfolio may invest up to 35% of its total assets (taken at current value
and subject to restrictions appearing elsewhere in this Prospectus), in U.S.
Government securities (securities issued or guaranteed as to principal and
interest by the United States or its agencies or instrumentalities), and
corporate debt securities which are rated at the time of purchase Baa or better
by Moody's Investors Service, Inc. or BBB or better by Standard & Poor's
Corporation or which, if unrated, are deemed to be of comparable quality by the
Fund's Trustees (see "General Portfolio Techniques" below for a discussion of
the characteristics and risks of investments in fixed-income securities rated
Baa or BBB), convertible securities, money market instruments, repurchase
agreements, options and futures (see "General Portfolio Techniques" below and in
the Statement of Additional Information). The CAPITAL GROWTH PORTFOLIO may also
purchase unit offerings (where corporate debt securities are offered as a unit
with convertible securities, preferred or common stocks, warrants, or any
combination thereof) (see the discussion of warrants under "General Portfolio
Techniques" below). U.S. Government securities are described above and in the
Statement of Additional Information under "The Quality Income Plus Portfolio."
 
There may be periods during which, in the opinion of the Investment Manager,
market conditions warrant reduction of some or all of the CAPITAL GROWTH
PORTFOLIO's securities holdings. During such periods, the CAPITAL GROWTH
PORTFOLIO may adopt a temporary "defensive" posture in which greater than 35% of
its total assets are invested in cash or money market instruments which would be
eligible investments for the Fund's MONEY MARKET PORTFOLIO (as set forth above
under "The Money Market Portfolio").
 
The CAPITAL GROWTH PORTFOLIO may enter into repurchase agreements, invest in
foreign securities (including American Depository Receipts, European Depository
Receipts or other similar securities convertible into securities of foreign
issuers), invest in zero coupon securities, invest in real estate investment
trusts, lend its portfolio securities, purchase securities on a when-issued or
delayed delivery basis or a "when, as and if issued" basis, and purchase or sell
securities on a forward commitment basis, in each case in accordance with the
description of those investments and techniques (and subject to the risks) set
forth under "General Portfolio Techniques" below and in the Statement of
Additional Information.

THE GLOBAL DIVIDEND GROWTH PORTFOLIO
 
The investment objective of the GLOBAL DIVIDEND GROWTH PORTFOLIO is to provide
reasonable current income and long-term growth of income and capital. This
objective is fundamental and may not be changed without shareholder approval.
There is no assurance that the objective will be achieved. The GLOBAL DIVIDEND
GROWTH PORTFOLIO seeks to achieve its investment objective primarily through
investments in common stock of companies, issued by issuers worldwide, with a
record of paying dividends and the potential for increasing dividends. The
following policies may be changed by the Trustees of the Fund without
shareholder approval:
 
The GLOBAL DIVIDEND GROWTH PORTFOLIO will invest at least 65% of its total
assets in dividend-paying equity securities issued by issuers located in various
countries around the world. The Portfolio's investment portfolio will also be
invested in at least three separate countries.
 
The GLOBAL DIVIDEND GROWTH PORTFOLIO will maintain a flexible investment policy
and, based on a worldwide investment strategy, will invest in a diversified
portfolio of securities of companies located throughout the world. The
Investment Manager will seek those companies with what, in its opinion, is a
strong record of earnings. The percentage of the GLOBAL DIVIDEND GROWTH
PORTFOLIO's assets invested in particular geographic sectors will shift from
time to time in accordance with the judgement of the Investment Manager.
 
Up to 35% of the value of the GLOBAL DIVIDEND GROWTH PORTFOLIO's total assets
may be invested in: (a) convertible debt securities, convertible preferred
securities, warrants (see "General Portfolio Techniques" below), U.S. Government
securities (securities issued or guaranteed as to principal and interest by the
United States or its agencies and instrumentalities), fixed-income securities
issued by foreign governments and international organizations, investment grade
corporate debt securities and/or money market instruments when, in the opinion
of the Investment Manager, the projected total return on such securities is
equal to or greater than the expected total return on equity securities or when
such holdings might be expected to reduce the volatility of the portfolio (for
purposes of this provision, the term "total return" means the difference between
the cost of a security and the aggregate of its market value and dividends
received) and forward foreign currency exchange contracts, futures contracts and
options (see "General Portfolio Techniques" below and in the Statement of
Additional Information); or (b) money market instruments under any one or more
of the following circumstances: (i) pending investment of proceeds of sale of
the Portfolio's shares or of portfolio securities; (ii) pending settlement of
purchases of portfolio securities; or (iii) to maintain liquidity for the
purpose of meeting anticipated redemptions. The term investment grade consists
of debt instruments rated Baa or higher by Moody's Investors Service, Inc. or
BBB or higher by Standard & Poor's Corporation or, if not rated, determined to
be of comparable quality by the Investment Manager (see "General Portfolio
Techniques" below for a discussion of the characteristics and risks of
investments in fixed-income securities rated Baa or BBB). U.S. Government
securities are described above and in the Statement of Additional Information
under "The Quality Income Plus Portfolio."
 
The GLOBAL DIVIDEND GROWTH PORTFOLIO may also invest in securities of foreign
issuers in the form of American Depository Receipts, European Depository
Receipts or other similar securities convertible into securities of foreign
issuers, invest in zero coupon securities, purchase equity and fixed-income
securities which are issued in private placements and invest up to 10% of its
total assets in securities issued by other investment companies (see the
discussion of these securities under "General Portfolio Techniques" below).
 
Notwithstanding the GLOBAL DIVIDEND GROWTH PORTFOLIO's investment objective of
seeking total return, the Portfolio may, for "defensive" purposes, without
limitation, invest in: obligations of the United States Government, its agencies
or instrumentalities; cash and cash equivalents in major currencies; repurchase
agreements; and money market instruments which would be eligible investments for
the Fund's MONEY MARKET PORTFOLIO (as set forth above under "The Money Market
Portfolio").
 
Investors should carefully consider the risks of investing in securities of
foreign issuers and securities denominated in non-U.S. currencies (see "General
Portfolio Techniques" below for a discussion of the characteristics and risks of
investments in foreign securities).
 
The GLOBAL DIVIDEND GROWTH PORTFOLIO may enter into repurchase agreements,
invest in real estate investment trusts, lend its portfolio securities, purchase
securities on a when-issued or delayed delivery basis or a "when, as and if
issued" basis, and purchase or sell securities on a forward commitment basis, in
each case in accordance with the description of those investments and techniques
(and subject to the risks) set forth under "General Portfolio Techniques" below
and in the Statement of Additional Information.
 
THE EUROPEAN GROWTH PORTFOLIO
 
The investment objective of the EUROPEAN GROWTH PORTFOLIO is to maximize the
capital appreciation of its investments. There is no assurance that the
objective will be achieved. The investment objective of the EUROPEAN GROWTH
PORTFOLIO may not be changed without the approval of the shareholders of the
EUROPEAN GROWTH PORTFOLIO. The following policies may be changed by the Board of
Trustees without shareholder approval:
 
The EUROPEAN GROWTH PORTFOLIO seeks to achieve its investment objective by
investing at least 65% of its total assets in securities issued by issuers
located in countries located in Europe. Such issuers will include companies (i)
which are organized under the laws of a European country and have a principal
office in a
 
                                       22
<PAGE>
European country, or (ii) which derive 50% or more of their total revenues from
business in Europe, or (iii) the equity securities of which are traded
principally on a stock exchange in Europe.
 
The principal countries in which such issuers will be located are France, the
United Kingdom, Germany, the Netherlands, Spain, Sweden, Switzerland and Italy.
The Portfolio's investment portfolio will be invested in at least three separate
countries.
 
The securities invested in will primarily consist of equity securities issued by
companies based in European countries, but may also include fixed-income
securities issued or guaranteed by European governments, when it is deemed that
such investments are consistent with the EUROPEAN GROWTH PORTFOLIO's investment
objective. For example, there may be times when the Investment Manager or the
Sub-Adviser determines that the prices of government securities are more likely
to appreciate than those of equity securities. Such an occasion might arise when
inflation concerns have led to general increases in interest rates. Such
fixed-income securities which will be purchased by the Portfolio are likely to
be obligations of the treasuries of one of the major European nations. In
addition, the EUROPEAN GROWTH PORTFOLIO may invest in fixed-income securities
which are, either alone or in combination with a warrant, option or other right,
convertible into the common stock of a European issuer, when the Investment
Manager or the Sub-Adviser determines that such securities are more likely to
appreciate in value than the common stock of such issuers or when the Investment
Manager or the Sub-Adviser wishes to hedge the risk inherent in the direct
purchase of the equity of a given issuer. The EUROPEAN GROWTH PORTFOLIO will
select convertible securities of issuers whose common stock has, in the opinion
of the Investment Manager or the Sub-Adviser, a superior investment potential
(see "General Portfolio Techniques" below). The EUROPEAN GROWTH PORTFOLIO may
also purchase equity and fixed-income securities which are issued in private
placements and warrants or other securities conveying the right to purchase
common stock, and may invest up to 10% of its total assets in securities issued
by other investment companies (see the discussion of these securities under
"General Portfolio Techniques" below).
 
The remainder of the assets of the EUROPEAN GROWTH PORTFOLIO, equalling, at
times, up to 35% of the Portfolio's total assets, may be invested in equity
and/or governmental and convertible securities issued by issuers located
anywhere in the world, including the United States, subject to the Portfolio's
investment objective. In addition, this portion of the portfolio will consist of
various other financial instruments such as forward foreign currency exchange
contracts, futures contracts and options (see "General Portfolio Techniques"
below and in the Statement of Additional Information). U.S. Government
securities are described above and in the Statement of Additional Information
under "The Quality Income Plus Portfolio."
 
It is anticipated that the securities held by the EUROPEAN GROWTH PORTFOLIO in
its portfolio will be denominated, principally, in liquid European currencies.
Such currencies include the German mark, French franc, British pound, Dutch
guilder, Swiss franc, Swedish krona, Italian lira, and Spanish peseta. In
addition, the Portfolio may hold securities denominated in the European Currency
Unit (a weighted composite of the currencies of member states of the European
Monetary System). Securities of issuers within a given country may be
denominated in the currency of a different country.
 
The EUROPEAN GROWTH PORTFOLIO may also invest in securities of foreign issuers
in the form of American Depository Receipts, European Depository Receipts or
other similar securities convertible into securities of foreign issuers (see the
discussion of these securities under "General Portfolio Techniques" below).
 
There may be periods during which market conditions warrant reduction of some or
all of the EUROPEAN GROWTH PORTFOLIO's securities holdings. During such periods,
the Portfolio may adopt a temporary "defensive" posture in which greater than
35% of its total assets are invested in cash or money market instruments which
would be eligible investments for the Fund's MONEY MARKET PORTFOLIO (as set
forth above under "The Money Market Portfolio").
 
Investors should carefully consider the risks of investing in securities of
foreign issuers and securities denominated in non-U.S. currencies (see "General
Portfolio Techniques" below for a discussion of the characteristics and risks of
investments in foreign securities).
 
The EUROPEAN GROWTH PORTFOLIO may enter into repurchase agreements, invest in
zero coupon securities, lend its portfolio securities, purchase securities on a
when-issued or delayed delivery basis or a "when, as and if issued" basis, and
purchase or sell securities on a forward commitment basis, in each case in
accordance with the description of those investments and techniques (and subject
to the risks) set forth under "General Portfolio Techniques" below and in the
Statement of Additional Information.
 
THE PACIFIC GROWTH PORTFOLIO
 
The investment objective of the PACIFIC GROWTH PORTFOLIO is to maximize the
capital appreciation of its investments. There is no assurance that the
objective will be achieved. The investment objective of the PACIFIC GROWTH
PORTFOLIO may not be changed without the approval of the shareholders of the
PACIFIC GROWTH PORTFOLIO. The following policies may be changed by the Board of
Trustees without shareholder approval:
 
The PACIFIC GROWTH PORTFOLIO seeks to achieve its investment objective by
investing at least 65% of its total assets in securities issued by issuers
located in Asia, Australia and New Zealand. Such issuers will include companies
which are organized under the laws of an Asian country, Australia or New Zealand
and have a principal office in an Asian country, Australia or New Zealand, or
which derive 50% or more of their total revenues from business in an Asian
country, Australia or New Zealand.
 
                                       23
<PAGE>
The principal countries in which such issuers will be located are Japan,
Australia, Malaysia, Singapore, Hong Kong, Thailand, the Philippines, Indonesia,
Taiwan and South Korea. The Portfolio's investment portfolio will be invested in
at least three separate countries.
 
The PACIFIC GROWTH PORTFOLIO may invest more than 25% of its total assets in
Japan, reflecting the dominance of the Japanese stock market in the Pacific
basin. The concentration of the Portfolio's assets in Japanese issuers will
subject the PACIFIC GROWTH PORTFOLIO to the risks of adverse social, political
or economic events which occur in Japan. Specifically, investments in the
Japanese stock market may entail a higher degree of risk than investments in
other markets as, by fundamental measures of corporate valuation, such as its
high price-earnings ratios and low dividend yields, the Japanese market as a
whole may appear expensive relative to other world stock markets (I.E., the
prices of Japanese stocks may be relatively high). In addition, the prices of
securities traded on the Japanese markets may be more volatile than many other
markets.
 
The PACIFIC GROWTH PORTFOLIO also may invest over 25% of its total assets in
securities issued by issuers located in Hong Kong. In common with the other
stock markets of the Pacific Basin, the Hong Kong stock market is more volatile,
as measured by standard deviation, than the major equity markets of North
America and Europe. On July 1, 1997, Hong Kong became part of the People's
Republic of China, and forms a Special Administrative Region within that
country. The Government of China has indicated that it will not seek to alter
the free market-oriented economic system of Hong Kong for at least fifty years
following 1997.
 
The PACIFIC GROWTH PORTFOLIO may also invest over 25% of its total assets in
securities issued by issuers located in Malaysia. The Malaysian stock market may
also be more volatile than many other markets and, as in the case of other
international equity markets, the value of equities can be impacted by
unforeseen, adverse developments in the macro-economy or currency, political
and/or social instability, government regulatory changes or individual corporate
developments.
 
The securities invested in will primarily consist of equity securities issued by
companies based in Asian countries, Australia and New Zealand which the
Investment Manager and/or Sub-Adviser believe are most likely to help the
PACIFIC GROWTH PORTFOLIO meet its investment objective, but may also include
fixed-income securities issued or guaranteed by (I.E., are the direct
obligations of) the governments of such countries, when it is deemed by the
Investment Manager or Sub-Adviser that such investments are consistent with the
Portfolio's investment objective. For example, there may be times when the
Investment Manager or Sub-Adviser determines that the prices of government
securities are more likely to appreciate than those of equity securities. Such
an occasion might arise when inflation concerns have led to general increases in
interest rates. Such fixed-income securities which will be purchased by the
Portfolio are likely to be obligations of the treasuries of Australia or Japan.
In addition, the PACIFIC GROWTH PORTFOLIO may invest in fixed-income securities
which are, either alone or in combination with a warrant, option or other right,
convertible into the common stock of an issuer, when the Investment Manager or
the Sub-Adviser determines that such securities are more likely to appreciate in
value than the common stock of such issuers or when the Investment Manager or
Sub-Adviser wishes to hedge the risk inherent in the direct purchase of the
equity of a given issuer, by receiving a steady stream of interest payments. The
PACIFIC GROWTH PORTFOLIO will select convertible securities of issuers whose
common stock has, in the opinion of the Investment Manager or Sub-Adviser, a
potential to appreciate in price (see "General Portfolio Techniques" below). The
PACIFIC GROWTH PORTFOLIO may also purchase equity and fixed-income securities
which are issued in private placements and warrants or other securities
conveying the right to purchase common stock, and may invest up to 10% of its
total assets in securities issued by other investment companies (see the
discussion of these securities under "General Portfolio Techniques" below).
 
The decisions of the Investment Manager and Sub-Adviser to invest in securities
for the PACIFIC GROWTH PORTFOLIO will be based on a general strategy of
selecting those issuers which they believe have shown a high rate of growth in
earnings. Moreover, securities will primarily be selected which possess, on both
an absolute basis and as compared with other securities in their region and
around the world, attractive price/earnings, price/cash flow and price/revenue
ratios.
 
The remainder of the assets of the PACIFIC GROWTH PORTFOLIO, equalling, at
times, up to 35% of the Portfolio's total assets, may be invested in equity
and/or fixed-income and convertible securities issued by issuers located
anywhere in the world, including the United States, subject to the Fund's
investment objective. In addition, this portion of the portfolio will consist of
various other financial instruments such as forward foreign currency exchange
contracts, futures contracts and options (see "General Portfolio Techniques"
below and in the Statement of Additional Information). U.S. government
securities are described above and in the Statement of Additional Information
under "The Quality Income Plus Portfolio."
 
It is anticipated that the securities held by the PACIFIC GROWTH PORTFOLIO in
its portfolio will be denominated, principally, in the liquid Asian currencies
and the Australian dollar. Such currencies include the Japanese yen, Malaysian
ringgit, Singapore dollar, Hong Kong dollar, Thai baht, Philippine peso,
Indonesia rupiah, Taiwan dollar and South Korean won. Securities of issuers
within a given country may be denominated in the currency of a different
country.
 
The PACIFIC GROWTH PORTFOLIO may also invest in securities of foreign issuers in
the form of American Depository Receipts, European Depository Receipts or other
similar securities convertible into securities of foreign issuers (see the
discussion of these securities under "General Portfolio Techniques" below).
 
There may be periods during which market conditions warrant reduction of some or
all of the PACIFIC GROWTH PORTFOLIO's securities
 
                                       24
<PAGE>
holdings. During such periods, the Portfolio may adopt a temporary "defensive"
posture in which greater than 35% of its net assets are invested in cash or
money market instruments that would be eligible investments for the Fund's MONEY
MARKET PORTFOLIO (as set forth above under "The Money Market Portfolio").
 
Investors should carefully consider the risks of investing in securities of
foreign issuers and securities denominated in non-U.S. currencies (see "General
Portfolio Techniques" below for a discussion of the characteristics and risks of
investments in foreign securities). In particular, the foreign securities in
which the PACIFIC GROWTH PORTFOLIO will be investing may be issued by issuers
located in developing countries. Compared to the United States and other
developed countries, developing countries may have relatively unstable
governments, economies based on only a few industries, and securities markets
which trade a small number of securities. Prices on these securities tend to be
especially volatile and, in the past, securities in these countries have offered
greater potential for gain (as well as loss) than securities of companies
located in developed countries.
 
The PACIFIC GROWTH PORTFOLIO may enter into repurchase agreements, invest in
zero coupon securities, lend its portfolio securities, purchase securities on a
when-issued or delayed delivery basis or a "when, as and if issued" basis, and
purchase or sell securities on a forward commitment basis, in each case in
accordance with the description of those investments and techniques (and subject
to the risks) set forth under "General Portfolio Techniques" below and in the
Statement of Additional Information.
 
THE CAPITAL APPRECIATION PORTFOLIO
 
The investment objective of the CAPITAL APPRECIATION PORTFOLIO is long-term
capital appreciation. There is no assurance that the objective will be achieved.
The investment objective of the CAPITAL APPRECIATION PORTFOLIO may not be
changed without the approval of the shareholders of the CAPITAL APPRECIATION
PORTFOLIO. The following policies may be changed by the Board of Trustees
without shareholder approval:
 
The CAPITAL APPRECIATION PORTFOLIO seeks to achieve its investment objective by
investing, under normal circumstances, at least 65% of its total assets in the
common stocks of U.S. companies that, in the opinion of the Investment Manager,
offer the potential for either superior earnings growth and/or appear to be
undervalued.
 
The Investment Manager will base the selection of stocks for the portfolio of
the CAPITAL APPRECIATION PORTFOLIO on research and analysis, taking into
account, among other factors, a company's price/earnings ratio (that is, whether
the current stock price appears undervalued in relation to earnings, projected
cash flow, or asset value per share; or the price-to-earnings ratio is
attractive relative to the company's underlying earnings growth rate), growth in
sales, market-to-book ratio, the quality of a company's balance sheet,
sales-per-share and profitability in order to determine whether the current
market valuation is less than the Investment Manager's view of a company's
intrinsic value. Also, when reviewing investments for selection, the Investment
Manager will consider the following characteristics of a company: capable
management; attractive business niches; pricing flexibility; sound financial and
accounting practices and a demonstrated ability or prospects to consistently
grow revenues, earnings and cash flow. Stocks may also be selected on the basis
of whether the Investment Manager believes that the potential exists for some
catalyst (such as increased investor attention, asset sales, a new
product/innovation, or a change in management) to cause the stock's price to
rise. Such factors are part of the Investment Manager's overall investment
selection process.
 
The Investment Manager has no general criteria as to asset size, earnings or
industry type which would make an investment unsuitable for purchase by the
CAPITAL APPRECIATION PORTFOLIO. In addition, since the Investment Manager is
seeking investments in companies whose securities may appear to be undervalued,
there is no limitation on the stock price of any particular investment. However,
as a result of the selection process, which focuses on fundamentals in relation
to prices, such review of investments will include companies with low-priced
stocks. In this category are large companies with low-priced stocks (so-called
"fallen angels") which, in the opinion of the Investment Manager, may appear to
be undervalued because they are overlooked by many investors, may not be closely
followed through investment research and/or their prices may reflect pessimism
about the companies' (and/or their industries') outlook. Such companies, by
virtue of their stock price, may be takeover candidates. Low-priced stocks are
also associated with smaller companies whose securities' value may reflect a
discount because of smaller size and lack of research coverage, emerging growth
companies and private companies undergoing their initial public offering. The
CAPITAL APPRECIATION PORTFOLIO will invest in companies of all sizes. For a
discussion of the risks of investing in the securities of such companies, see
below.
 
Consequently, the CAPITAL APPRECIATION PORTFOLIO looks for quality businesses
with an investment outlook based upon a mix of growth potential, financial
strength and fundamental value. The focus on price and fundamentals sets the
Portfolio apart from pure "growth" or pure "value" funds. The CAPITAL
APPRECIATION PORTFOLIO's holdings will be widely diversified by industry and
company and under most circumstances, at the time of initial purchase, the
average position will be less than 1.5% of the Portfolio's net assets.
 
In addition to U.S. common stock, up to 35% of the CAPITAL APPRECIATION
PORTFOLIO's total assets may be invested in debt or preferred equity securities
convertible into or exchangeable for equity securities, rights and warrants,
when considered by the Investment Manager to be consistent with the Portfolio's
investment objective. (For a discussion of each of these types of securities,
see "General Portfolio Techniques" below.)
 
                                       25
<PAGE>
The CAPITAL APPRECIATION PORTFOLIO may also invest in other debt securities
without regard to quality or rating, if in the opinion of the Investment Manager
such securities meet the investment criteria of the CAPITAL APPRECIATION
PORTFOLIO. However, the CAPITAL APPRECIATION PORTFOLIO will not purchase a
non-investment grade debt security (or junk bond) if, immediately after such
purchase, the Portfolio would have more than 5% of its total assets invested in
such securities. See "General Portfolio Techniques" below for a discussion of
investment in securities rated Baa by Moody's Investors Service, Inc. or BBB by
Standard & Poor's Corporation (the lowest credit ratings designated "investment
grade") and a discussion of investments in securities rated lower than
investment grade.
 
The securities in which the CAPITAL APPRECIATION PORTFOLIO invests may or may
not be listed on a national stock exchange, but if they are not so listed will
generally have an established over-the-counter market.
 
Given the investment risks described below, an investment in shares of the
CAPITAL APPRECIATION PORTFOLIO should not be considered a complete investment
program and is not appropriate for all investors. Investors should carefully
consider their ability to assume these risks before making an investment in the
CAPITAL APPRECIATION PORTFOLIO.
 
The net asset value of the shares of the CAPITAL APPRECIATION PORTFOLIO will
fluctuate with changes in the market value of its portfolio securities. The
market value of the portfolio securities of the CAPITAL APPRECIATION PORTFOLIO
will increase or decrease due to a variety of economic, market or political
factors which cannot be predicted. The CAPITAL APPRECIATION PORTFOLIO is
intended for long-term investors who can accept the risks involved in seeking
long-term capital appreciation through the investment primarily in the
securities of companies that offer the potential for either superior earnings
growth and/or appear to be undervalued. In selecting investments for the CAPITAL
APPRECIATION PORTFOLIO, the Investment Manager has no general criteria as to a
company's asset size, earnings or industry type. It should be recognized that
investing in such companies involves greater risk than is customarily associated
with investing in more established companies.
 
The CAPITAL APPRECIATION PORTFOLIO may invest in securities of companies that
are not well known to the investing public or followed by many securities
analysts, with the result that there may be less publicly available information
concerning such securities. Also, these securities may be more volatile in price
and have lower trading volumes. In addition, while companies in which the
CAPITAL APPRECIATION PORTFOLIO may invest often have sales and earnings growth
rates which may exceed those of large companies and may be reflected in more
rapid share price appreciation, such companies may have limited operating
histories, product lines, markets or financial resources and they may be
dependent upon one-person management. These companies may be subject to intense
competition from larger companies. The securities of such companies may have
limited marketability and may be subject to more abrupt or erratic movements in
price than securities of larger companies or in the market averages in general.
In the case of securities of large companies with lower-priced stock (the
so-called "fallen angels"), the risk associated with such investment is that the
price may continue to fall.
 
There may be periods during which, in the opinion of the Investment Manager,
market conditions warrant a reduction of some or all of the CAPITAL APPRECIATION
PORTFOLIO's securities holdings. During such periods, the Portfolio may adopt a
temporary "defensive" posture in which greater than 35% of its total assets is
invested in cash or money market instruments, including obligations issued or
guaranteed as to principal or interest by the United States Government, its
agencies or instrumentalities, certificates of deposit, bankers' acceptances and
other obligations of domestic banks having total assets of $1 billion or more,
and short-term commercial paper of corporations organized under the laws of any
state or political subdivision of the United States.
 
The CAPITAL APPRECIATION PORTFOLIO may enter into repurchase agreements, invest
in foreign securities (including American Depository Receipts), zero coupon
securities and real estate investment trusts, invest up to 10% of its total
assets in securities issued by other investment companies, engage in futures
contracts and options transactions, lend its portfolio securities, purchase
securities which are issued in private placements or are otherwise not readily
marketable, purchase securities on a when-issued or delayed delivery basis or a
"when, as and if issued" basis, and purchase or sell securities on a forward
commitment basis, in each case in accordance with the description of these
investments and techniques (and subject to the risks) set forth under "General
Portfolio Techniques" below and in the Statement of Additional Information.
 
THE EQUITY PORTFOLIO
 
The portfolio of the EQUITY PORTFOLIO will be actively managed by the Investment
Manager with a view to achieving the EQUITY PORTFOLIO's primary investment
objective of growth of capital through investments in common stock of companies
believed by the Investment Manager to have potential for superior growth. As a
secondary objective, the EQUITY PORTFOLIO will seek income, but only when
consistent with its primary objective. There can be no assurance that the
objectives will be achieved.
 
The investment objectives of the EQUITY PORTFOLIO may not be changed without the
approval of the shareholders of the EQUITY PORTFOLIO. The following policies may
be changed by the Trustees of the Fund without shareholder approval:
 
Consistent with its primary investment objective, the EQUITY PORTFOLIO will
invest principally in common stocks, under most conditions, but may also invest
in corporate debt securities which are rated at the time of purchase Aa or
better by Moody's Investors Service, Inc. or AA or better by Standard & Poor's
Corporation (the Portfolio may continue to hold a security even if its quality
rating is reduced by a rating service below those specified; see "General
Portfolio Techniques" below for a discussion of the risks of holding lower-rated
securities), U.S. Government
 
                                       26
<PAGE>
securities (securities issued or guaranteed as to principal and interest by the
United States, its agencies or instrumentalities), preferred stocks, securities
convertible into common stock, including convertible debt obligations and
convertible preferred stocks, and warrants (see the discussion of convertible
securities and warrants under "General Portfolio Techniques" below). The EQUITY
PORTFOLIO will invest at least 65% of its net assets at all times, except for
temporary and defensive purposes, in equity securities and securities
convertible into equity securities. In determining the percentage of the EQUITY
PORTFOLIO's assets to be invested in equity securities, the Investment Manager
may employ valuation models based on various economic and market indicators.
Equity assets will be distributed among high-quality, large-capitalization,
dividend-oriented stocks, stocks of small-and medium-sized growth-oriented
companies, and stocks which it believes to be undervalued regardless of
capitalization size. Funds will be allocated among these different approaches
based on the Investment Manager's evaluation of economic and market trends and
on valuation parameters such as price/earnings ("P/E") ratios, price/book
ratios, dividend yields, P/E to growth rate ratios, and/or dividend discount
models. While the EQUITY PORTFOLIO may not invest in securities of foreign
issuers, it may invest in (a) securities of Canadian issuers registered under
the Securities Exchange Act of 1934 and (b) American Depository Receipts
("ADRs") (see the discussion of ADRs under "General Portfolio Techniques"
below).
 
In order to maintain a liquid position or in periods in which general market
conditions warrant, in the opinion of the Investment Manager, the adoption of a
temporary "defensive" posture, part of the assets of the EQUITY PORTFOLIO may be
invested in money market instruments, including obligations issued or
guaranteed as to principal or interest by the United States, its agencies or
instrumentalities, certificates of deposit, bankers' acceptances and other
obligations of domestic banks having total assets of $1 billion or more, and
short-term commercial paper of corporations organized under the laws of any
state or political subdivision of the United States.
 
The EQUITY PORTFOLIO may enter into repurchase agreements, invest in zero coupon
securities, invest in real estate investment trusts, lend its portfolio
securities, purchase securities on a when-issued or delayed delivery basis or a
"when, as and if issued" basis, and purchase or sell securities on a forward
commitment basis, in each case in accordance with the description of those
techniques (and subject to the same risks) set forth under "General Portfolio
Techniques" below and in the Statement of Additional Information.
 
THE S&P 500 INDEX PORTFOLIO
 
The investment objective of the S&P 500 INDEX PORTFOLIO is to provide investment
results that, before expenses, correspond to the total return (I.E., the
combination of capital changes and income) of the Standard &
Poor's-Registered Trademark- 500 Composite Stock Price Index (the "S&P 500
Index"). This is a fundamental policy and cannot be changed without the approval
of the shareholders of the S&P 500 INDEX PORTFOLIO. There is no assurance that
the investment objective of the S&P 500 INDEX PORTFOLIO will be achieved. The
following policies may be changed by the Trustees of the Fund without
shareholder approval:
 
The S&P 500 INDEX PORTFOLIO seeks to achieve its objective by investing, under
normal circumstances (including the attainment by the Portfolio of sufficient
asset size), at least 80% of its total assets in common stocks included in the
S&P 500 Index in approximately the same weightings as the Index. The Portfolio
intends to invest in substantially all of the stocks that comprise the S&P 500
Index in approximately the same weightings as they are represented in the Index.
The Portfolio operates as a "straight" index fund and will not be actively
managed; as such, adverse performance of a security will ordinarily not result
in the elimination of the security from the portfolio of the S&P 500 INDEX
PORTFOLIO. The Portfolio will remain fully invested in common stocks even when
stock prices are generally falling. Ordinarily, portfolio securities will not be
sold except to reflect additions or deletions of the stocks that comprise the
S&P 500 Index, including mergers, reorganizations and similar transactions, or
as may be necessary to satisfy redemption requests. Because of the difficulty
and expense of executing relatively small stock transactions, until the S&P 500
INDEX PORTFOLIO attains a sufficient level of assets (approximately $10
million), the Portfolio may have its portfolio weighted differently from the S&P
500 Index and may not invest in all 500 stocks represented in the Index.
 
Over the long term, the Investment Manager seeks a correlation between the
performance of the S&P 500 INDEX PORTFOLIO, before expenses, and that of the S&P
500 Index of 0.95 or better. A figure of 1.00 would indicate perfect
correlation. The Portfolio's ability to correlate its performance, before
expenses, with the S&P 500 Index may be affected by, among other things, changes
in securities markets, the manner in which the S&P 500 Index is calculated and
the timing of purchases and redemptions. The Portfolio's ability to correlate
its performance to the Index also depends to some extent on the size of the
portfolio of the S&P 500 INDEX PORTFOLIO and the size of cash flows into and out
of the Portfolio. To accommodate these cash flows, investment changes may be
made to maintain the similarity of the Portfolio's portfolio to the S&P 500
Index to the maximum practicable extent. The Investment Manager regularly
monitors the correlation and, in the event the desired correlation is not
achieved, the Investment Manager will determine what additional investment
changes may need to be made.
 
The S&P 500 INDEX PORTFOLIO may purchase and sell stock index futures contracts,
for the following reasons: to simulate full investment in the S&P 500 Index
while retaining a cash balance for portfolio management purposes, to facilitate
trading, to reduce transaction costs or to seek higher investment returns when a
futures contract is priced more attractively than stocks comprising the S&P 500
Index (see the discussion of stock index futures under "General Portfolio
Techniques" below and in the Statement of Additional Information).
 
                                       27
<PAGE>
ADDITIONAL INFORMATION CONCERNING THE S&P 500 INDEX. The S&P 500 Index is a
well-known stock market index that includes common stocks of 500 companies from
several industrial sectors representing a significant portion of the market
value of all common stocks publicly traded in the United States, most of which
are listed on the New York Stock Exchange. Stocks in the S&P 500 Index are
weighted according to their market capitalization (I.E., the number of shares
outstanding multiplied by the stock's current price). The Investment Manager
believes that the performance of the S&P 500 Index is representative of the
performance of publicly traded common stocks in general. The composition of the
S&P 500 Index is determined by Standard & Poor's, a division of The McGraw-Hill
Companies, Inc. ("S&P"), and is based on such factors as the market
capitalization and trading activity of each stock and its adequacy as a
representation of stocks in a particular industry group, and may be changed from
time to time.
 
"Standard & Poor's-Registered Trademark-," "S&P-Registered Trademark-," "S&P
500-Registered Trademark-," "Standard & Poor's 500," and "500" are trademarks of
The McGraw-Hill Companies, Inc. and have been licensed for use by the S&P 500
INDEX PORTFOLIO. The Portfolio is not sponsored, endorsed, sold or promoted by
S&P, and S&P makes no representation regarding the advisability of investing in
the S&P 500 INDEX PORTFOLIO. (Please see the Statement of Additional Information
which sets forth certain additional disclaimers and limitations of liabilities
on behalf on S&P.)
 
CASH FLOWS; EXPENSES. The ability of the S&P 500 INDEX PORTFOLIO to meet its
investment objective depends to some extent on the Investment Manager's ability
to manage cash flows (primarily from purchases and redemptions and distributions
from the Portfolio's portfolio investments). Generally, the Investment Manager
will employ stock index futures to provide liquidity necessary to meet
anticipated redemptions or for day-to-day operating purposes. In addition, if
considered appropriate, a portion of the Portfolio's assets not exceeding 20% of
its total assets may be invested in money market instruments. The Investment
Manager will also made investment changes to the portfolio of the S&P 500 INDEX
PORTFOLIO to accommodate cash flows while continuing to seek to replicate the
total return of the S&P 500 Index. Investors should also be aware that the S&P
500 Index is a hypothetical number which does not take into account brokerage
commissions and other transaction costs, custody and other costs of investing,
which will be borne by the Fund, and any incremental operating costs (E.G.,
transfer agency, accounting) borne by the Portfolio. Finally, since the
Portfolio seeks to provide investment results that, before expenses, correspond
to the total return of the S&P 500 Index, the Investment Manager will generally
not attempt to judge the merits of any particular security as an investment.
 
TEMPORARY INVESTMENTS. A portion of the S&P 500 INDEX PORTFOLIO's assets, not
exceeding 20% of its total assets, may be invested temporarily in money market
instruments under any one or more of the following circumstances: (a) pending
investment of proceeds of sale of shares of the Portfolio, (b) pending
settlement of purchases of portfolio securities, or (c) to maintain liquidity
for the purpose of meeting anticipated redemptions. The money market instruments
in which the Portfolio may invest are: certificates of deposit of U.S. domestic
banks with assets of $1 billion or more, bankers' acceptances, time deposits,
U.S. Government and U.S. Government agency securities, and commercial paper
rated within the two highest grades by S&P or Moody's Investors Service, Inc. or
which, if not rated, are of comparable quality as determined by the Fund's
Trustees, and which mature within one year from the date of purchase.
 
STANDARD & POOR'S DEPOSITARY RECEIPTS ("SPDRS"). The S&P 500 INDEX PORTFOLIO may
purchase interests in a unit investment trust holding a portfolio of securities
linked to the S&P 500 Index. SPDRs closely track the underlying portfolio of
securities, trade like a share of common stock and pay periodic dividends
proportionate to those paid by the portfolio of stocks that comprise the S&P 500
Index. The Portfolio may invest up to 10% of its total assets in the aggregate
in SPDRs and up to 5% of its total assets in SPDRs issued by a single unit
investment trust. As a holder of interest in a unit investment trust, the
Portfolio would indirectly bear its ratable share of that unit investment
trust's expenses. At the same time the Portfolio would continue to pay its own
management fees and other expenses, as a result of which the Portfolio and its
shareholders in effect will be absorbing duplicate levels of fees with respect
to investments in such unit investment trusts. The liquidity of small holdings
of SPDRs will depend upon the existence and liquidity of a secondary market.
 
The S&P 500 INDEX PORTFOLIO may enter into repurchase agreements, invest in zero
coupon securities and foreign securities (including American Depository
Receipts) of foreign corporations represented in the S&P 500 Index, and lend its
portfolio securities, in each case in accordance with the description of those
techniques (and subject to the same risks) set forth under "General Portfolio
Techniques" below and in the Statement of Additional Information.
 
THE COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO
 
The investment objective of the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO is
long-term capital growth. This is a fundamental policy and cannot be changed
without the approval of the shareholders of the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO. There is no assurance that the investment objective of the
COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO will be achieved. The following policies
may be changed by the Trustees of the Fund without shareholder approval:
 
The COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO seeks to achieve its investment
objective by investing, under normal circumstances, at least 80% of its net
assets in the common stock (including depository receipts, such as American
Depository Receipts or European Depository Receipts)(see "General Portfolio
Techniques" below) of U.S. and non-U.S. companies included in the
 
                                       28
<PAGE>
"Best Ideas" subgroup of "Global Investing: The Competitive Edge," a research
compilation assembled and maintained by Morgan Stanley Dean Witter Equity
Research ("MSDW Equity Research") and such Supplemental Securities (as defined
below) chosen by the Investment Manager.
 
MSDW EQUITY RESEARCH. MSDW Equity Research is recognized as a world leader in
global financial research and provides comprehensive research and in-depth
knowledge about general markets and specific companies from around the world. It
believes that companies with a sustainable competitive edge in the operations of
their businesses are worth more than their weaker competitors. Through its
ongoing research and analysis, MSDW Equity Research has developed and undertaken
a comprehensive study which it calls "Global Investing: The Competitive Edge"
which represents the list of those companies.
 
Specifically, MSDW Equity Research group's research analysts and strategists
presently evaluate approximately 2,000 companies in 21 industry sectors
worldwide (the "MSDW Covered Securities"). An initial comprehensive review was
conducted in October 1996 and identified 238 companies from the MSDW Covered
Securities (then nearly 1,650) as having a long-term sustainable competitive
advantage in the global arena (the "Competitive Edge List"). The criteria used
to select companies that have a global competitive advantage vary according to
industry sector. The Competitive Edge List is currently updated annually. From
the Competitive Edge List, MSDW Equity Research then assembled a subgroup of 40
companies which it considered at that time to be the most attractive investment
opportunities of the companies identified as having a long-term sustainable
competitive advantage in the global arena (the "Competitive Edge 'Best Ideas'
List"). MSDW Equity Research's Competitive Edge List and Competitive Edge "Best
Ideas" List are not compiled with any particular client or product in mind and
are not, and will not be, compiled with the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO in mind. When selecting the companies for its Competitive Edge "Best
Ideas" List, MSDW Equity Research does not take into account country or currency
risk, and country or industry sector diversification concerns. MSDW publishes
other lists of recommended securities that could be appropriate for Portfolio
investors but which will not be used by the Investment Manager for choosing
securities for the Portfolio. MSDW could at any time cease publishing the
Competitive Edge List and the Competitive Edge "Best Ideas" List. In that event
the Trustees of the Fund will make a determination of how to proceed in the best
interests of shareholders of the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO
consistent with the Portfolio's investment objective. A list of the companies
contained on the Competitive Edge "Best Ideas" List as of March 31, 1998 is set
forth in the Statement of Additional Information. The Competitive Edge "Best
Ideas" List is currently updated by MSDW Equity Research quarterly.
 
In accordance with the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO's investment
restrictions described below, the Portfolio will not invest 25% or more of the
value of its total assets in any one industry. In addition, as the Portfolio
principally invests in the securities of companies on the Competitive Edge "Best
Ideas" List, which currently consists of only 40 companies, the Portfolio will
invest in a relatively small universe of securities. Accordingly, the
COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO may be highly invested in any one
industry or country. It is the intention of the Investment Manager that at least
1% and not more than 5% of the Portfolio's net assets will be invested in each
company on the Competitive Edge "Best Ideas" List, determined at the time of
investment and subject to the specific investment policies and restrictions
described below. However, the Investment Manager may eliminate or reduce its
investment in any company on the Competitive Edge "Best Ideas" List below 1% of
the Portfolio's net assets, in the following circumstances: (a) the stock is no
longer publicly traded, such as in the case of a leveraged buyout or merger; (b)
in the view of the Investment Manager, there is a material adverse development
with respect to a company, including but not limited to the downgrading of the
company's rating by MSDW Equity Research; (c) concerns that, in view of the
price of the company's securities, the depth of the market in those securities
and the amount of those securities held or to be held by the Portfolio,
retaining shares of that company or making additional purchases would be
inadvisable because of liquidity concerns; or (d) the diversification and other
requirements that apply to registered investment companies. The Investment
Manager will monitor on an ongoing basis all companies falling within any of the
circumstances described in this paragraph, and may increase the Portfolio's
holdings in such company's shares when and if those conditions cease to exist.
The COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO will purchase any security which is
added to the Competitive Edge "Best Ideas" List, and will sell a security which
is eliminated from the Competitive Edge "Best Ideas" List and any related
Supplemental Security (as defined below), as soon as practicable after the
Competitive Edge "Best Ideas" List has been updated by MSDW Equity Research,
unless the Investment Manager decides to hold such security as a Supplemental
Security. Accordingly, securities may be purchased and sold by the Portfolio
when such purchases and sales would not be made under traditional investment
criteria. The Investment Manager will not have access to the Competitive Edge
"Best Ideas" List prior to its quarterly update by MSDW Equity Research.
 
While the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO intends to invest in
securities on the Competitive Edge "Best Ideas" List, the Portfolio may purchase
one or more supplemental securities ("Supplemental Securities") that are not
included on the Competitive Edge "Best Ideas" List but are on the Competitive
Edge List or, in the event no suitable securities are on the Competitive Edge
List, such other securities deemed suitable by the Investment Manager.
Supplemental Securities will generally be selected by the Investment Manager
from the same or similar industry sector as the security which they are
supplementing or replacing. Accordingly, the Portfolio's holdings may not be
limited to those on the Competitive Edge "Best Ideas" List. While there is no
limit on the total number of Supplemental Securities that the Portfolio may
hold, Supplemental Securities and all other securities that are not on the
Competitive Edge
 
                                       29
<PAGE>
"Best Ideas" List generally will not exceed 35% of the Portfolio's total assets.
In addition, each security on the Competitive Edge "Best Ideas" List which is
supplemented or replaced, together with its corresponding Supplemental
Securities, will have a combined weighting of no more than 5% of the Portfolio's
net assets, determined at the time of investment.
 
The COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO may invest up to 20% of its total
assets in money market instruments or cash. The money market instruments in
which the Portfolio may invest are securities issued or guaranteed by the U.S.
Government (Treasury bills, notes and bonds (including zero coupon securities)
(see "General Portfolio Techniques" below), obligations of American banks and
savings institutions having total assets of $1 billion or more, Eurodollar
certificates of deposit issued by foreign branches of domestic banks having
total assets of $1 billion or more, fully insured certificates of deposit, and
commercial paper of American issuers rated within the two highest grades by
Moody's Investors Service Inc. ("Moody's") or Standard & Poor's Corporation
("S&P") or, if not rated, issued by a company having an outstanding debt issue
rated at least AA by S&P or Aa by Moody's.
 
There may be periods during which market conditions warrant reduction of some or
all of the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO's securities holdings. During
such periods, the Portfolio may adopt a temporary "defensive" posture in which
up to 100% of the Portfolio's net assets are invested in cash or money market
instruments.
 
COMPETITIVE EDGE "BEST IDEAS" SELECTION. The net asset value of the Portfolio
will fluctuate depending upon, among other things, the performance of the
securities included on the Competitive Edge "Best Ideas" List, which currently
consists of 40 companies and which is only updated quarterly. The Portfolio is
subject to all the risks associated with investing in a small universe of
securities. There can be no assurance that the securities contained in the
Competitive Edge "Best Ideas" List will perform as anticipated. The selection of
companies on the Competitive Edge "Best Ideas" List is a subjective
determination by MSDW Equity Research. Past performance of the securities and
issuers included in the Competitive Edge "Best Ideas" List cannot be used to
predict future results of the Portfolio, which is actively managed by the
Investment Manager and the results of which are expected to vary from the
performance of the Competitive Edge "Best Ideas" List.
 
POTENTIAL INVESTMENT RESTRICTIONS AND CONSIDERATIONS. The activities of an
affiliate of the Investment Manager, including but not limited to Dean Witter
Reynolds Inc. ("DWR") or Morgan Stanley & Co. Incorporated ("Morgan Stanley"),
may from time to time limit the Portfolio's ability to purchase or sell
securities on the Competitive Edge "Best Ideas" List. For instance, when DWR or
Morgan Stanley or one of their affiliates is engaged in an underwriting or other
distribution of stock of an issuer, the Investment Manager may be prohibited
from purchasing the stock of that issuer for the Portfolio. In addition, the
Competitive Edge "Best Ideas" List is available to other clients of MSDW and its
affiliates, including the Investment Manager, as well as the Portfolio. The
lists are also subject to restrictions related to MSDW's other businesses and
particular securities may or may not be on the lists due to other business
concerns of, or legal restrictions applicable to, MSDW.
 
MSDW BUSINESSES. As a diversified financial services firm, with three primary
businesses--securities, asset management and credit services, MSDW provides a
wide range of financial services to issuers of securities and investors in
securities. MSDW and others associated with it may create markets or specialize
in, have positions in and affect transactions in securities of companies
included on its research lists and may also perform or seek to perform
investment banking services for those companies. Within the last three years
MSDW may have managed or co-managed public security offerings for companies
included on their research lists, and they or their employees may have a long or
short position on holdings in the securities, or options on securities, or other
related investments of companies included on their research lists.
 
The COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO may enter into repurchase
agreements, invest in foreign securities, forward foreign currency exchange
contracts, rights and warrants, private placements and futures contracts and
options, and lend its portfolio securities, in each case in accordance with the
description of those techniques (and subject to the same risks) set forth under
"General Portfolio Techniques" below and in the Statement of Additional
Information.
 
THE STRATEGIST PORTFOLIO
 
The investment objective of the STRATEGIST PORTFOLIO is to seek a high total
investment return through a fully managed investment policy utilizing equity,
fixed-income and money market securities, and the writing of covered call and
put options. This is a fundamental policy and cannot be changed without the
approval of the shareholders of the STRATEGIST PORTFOLIO. In seeking to achieve
its objective, the STRATEGIST PORTFOLIO actively allocates assets among the
major asset categories of equity securities, fixed-income securities and money
market instruments. Total investment return consists of current income
(including dividends, interest and, in the case of discounted instruments,
discount accretion) and capital appreciation. There can be no assurance that the
investment objective of the STRATEGIST PORTFOLIO will be achieved. The following
policies may be changed by the Trustees of the Fund without shareholder
approval:
 
The achievement of the STRATEGIST PORTFOLIO's investment objective depends on
the ability of the Investment Manager to assess the effect of economic and
market trends on different sectors of the market. The Investment Manager
believes that superior investment returns at a lower risk are achievable by
actively allocating resources to the equity, debt and money market sectors of
the market as opposed to relying solely on just one market. At times, the equity
market may hold a higher potential return than the debt market and would warrant
a higher asset allocation. The
 
                                       30
<PAGE>
reverse would be true when the bond market potential return is higher. Short
duration bonds and money market instruments can be used to soften market
declines when both bonds and equities are fully priced. Conserving capital
during declining markets can contribute to maximizing total return over a longer
period of time. In addition, the securities of companies within various economic
sectors may at times offer higher returns than other sectors and can thus
contribute to superior returns. Finally, the Investment Manager believes that
superior stock selection can also contribute to superior total return.
 
Within the equity sector, the Investment Manager actively allocates funds to
those economic sectors expected to benefit from major trends and to individual
stocks which are deemed to have superior investment potential. The STRATEGIST
PORTFOLIO may purchase equity securities (including warrants, convertible debt
obligations and convertible preferred stock) sold on the New York, American and
other stock exchanges and in the over-the-counter market. See the discussion of
convertible securities and warrants under " General Portfolio Techniques" below.
 
Within the fixed-income sector of the market, the Investment Manager seeks to
maximize the return on its investments by adjusting maturities and coupon rates
as well as by exploiting yield differentials among different types of investment
grade bonds. Fixed-income securities in which the STRATEGIST PORTFOLIO may
invest are short-term to intermediate (one to five year maturities) and
intermediate to long-term (greater than five year maturities) debt securities
and preferred stocks, including U.S. Government securities (securities issued or
guaranteed as to principal and interest by the United States or its agencies and
instrumentalities) and corporate securities which are rated at the time of
purchase Baa or better by Moody's Investor Service, Inc. or BBB or better by
Standard & Poor's Corporation, or which, if unrated, are deemed to be of
comparable quality by the Fund's Trustees (a description of corporate bond
ratings is contained in the Appendix). Fixed-income securities which may be
purchased include zero coupon securities. See the discussion of the
characteristics and risks of investments in fixed-income securities rated Baa or
BBB and zero coupon securities under "General Portfolio Techniques" below.
 
Within the money market sector of the market, the Investment Manager seeks to
maximize returns by exploiting spreads among short-term instruments. The
STRATEGIST PORTFOLIO may invest in money market securities which would be
eligible investments for the Fund's MONEY MARKET PORTFOLIO (as set forth above
under "The Money Market Portfolio").
 
The STRATEGIST PORTFOLIO may enter into repurchase agreements, invest in foreign
securities (including American Depository Receipts, European Depository Receipts
or other similar securities convertible into securities of foreign issuers),
invest in real estate investment trusts, lend its portfolio securities, invest
in futures contracts and options, purchase securities on a when-issued or
delayed delivery basis or a "when, as and if issued" basis, and purchase or sell
securities on a forward commitment basis, in each case in accordance with the
description of those investments and techniques (and subject to the risks) set
forth under "General Portfolio Techniques" below and in the Statement of
Additional Information.
 
GENERAL PORTFOLIO TECHNIQUES
 
FOREIGN SECURITIES. The EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH
PORTFOLIO will invest primarily in foreign securities. The GLOBAL DIVIDEND
GROWTH PORTFOLIO will invest a substantial portion of its assets in foreign
securities. The COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO may invest a substantial
portion of its assets in foreign securities. Each of the INCOME BUILDER
PORTFOLIO and the CAPITAL GROWTH PORTFOLIO may invest up to 25% of the value of
its total assets, at the time of purchase, in foreign securities (other than
securities of Canadian issuers registered under the Securities Exchange Act of
1934 or American Depository Receipts ("ADRs") (described below), on which there
is no such limit; investments in certain Canadian issuers may be speculative due
to certain political risks and may be subject to substantial price
fluctuations). The CAPITAL GROWTH PORTFOLIO's investments in unlisted foreign
securities are subject to the overall restrictions applicable to investments in
illiquid securities (see "Investment Restrictions"). Each of the HIGH YIELD
PORTFOLIO and the STRATEGIST PORTFOLIO may invest up to 20% of its total assets
in securities issued by foreign governments and other foreign issuers and in
foreign currency issues of domestic issuers, but not more than 10% of its total
assets in such securities, whether issued by a foreign or a domestic issuer,
which are denominated in foreign currency. The QUALITY INCOME PLUS PORTFOLIO may
invest up to 20% of its net assets in "Yankee government bonds," and up to 15%
of its net assets in "Yankee corporate bonds," which are U.S. dollar denominated
debt securities issued, respectively, by foreign governments or their respective
instrumentalities or agencies or by foreign corporations, which securities in
each case are either registered under the Securities Act of 1933, or eligible
for resale pursuant to Rule 144A under that Act and pay both principal and
interest in U.S. dollars. The UTILITIES PORTFOLIO may invest up to 20% of the
value of its total assets, at the time of purchase, in securities issued by
foreign issuers, with a maximum of 10% of the value of its total assets, at the
time of purchase, invested in such securities that are not ADRs. The CAPITAL
APPRECIATION PORTFOLIO may invest up to 10% of the value of its total assets in
foreign securities. The S&P 500 INDEX PORTFOLIO may purchase common stocks,
including American Depository Receipts, of foreign corporations represented in
the S&P 500 Index (such securities are listed on the New York Stock Exchange,
the American Stock Exchange or the NASDAQ Market System). The QUALITY INCOME
PLUS PORTFOLIO and the HIGH YIELD PORTFOLIO may invest in money market
obligations of domestic branches of foreign banks, or foreign branches of
domestic banks, including Eurodollar Certificates of Deposit, as set forth above
under the description of these Portfolios. The MONEY MARKET PORTFOLIO, the
UTILITIES PORTFOLIO, the INCOME BUILDER PORTFOLIO, the DIVIDEND GROWTH
PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO,
the EUROPEAN GROWTH PORTFOLIO, the PACIFIC
 
                                       31
<PAGE>
GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST
IDEAS" PORTFOLIO and the STRATEGIST PORTFOLIO may invest in Eurodollar
certificates of deposit issued by foreign branches of domestic banks having
total assets of $1 billion or more.
 
Foreign securities investments may be affected by changes in currency rates or
exchange control regulations, changes in governmental administration or economic
or monetary policy (in the United States and abroad) or changed circumstances in
dealings between nations. Fluctuations in the relative rates of exchange between
the currencies of different nations will affect the value of a Portfolio's
investments denominated in foreign currency. Changes in foreign currency
exchange rates relative to the U.S. dollar will affect the U.S. dollar value of
a Portfolio's assets denominated in that currency and thereby impact upon the
Portfolio's total return on such assets.
 
Foreign currency exchange rates are determined by forces of supply and demand on
the foreign exchange markets. These forces are themselves affected by the
international balance of payments and other economic and financial conditions,
government intervention, speculation and other factors. Moreover, foreign
currency exchange rates may be affected by the regulatory control of the
exchanges on which the currencies trade. The foreign currency transactions of a
Portfolio will be conducted on a spot basis or, in the case of the GLOBAL
DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH
PORTFOLIO, and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO, through forward
foreign currency exchange contracts (described below) or, in the case of those
four Portfolios and the CAPITAL APPRECIATION PORTFOLIO, futures contracts
(described below under "Options and Futures Transactions"). A Portfolio will
incur certain costs in connection with these currency transactions.
 
Investments in foreign securities will also occasion risks relating to political
and economic developments abroad, including the possibility of expropriations or
confiscatory taxation, limitations on the use or transfer of Portfolio assets
and any effects of foreign social, economic or political instability. Political
and economic developments in Europe, especially as they relate to changes in the
structure of the European Economic Community and the anticipated development of
a unified common market, may have profound effects upon the value of a large
segment of the GLOBAL DIVIDEND GROWTH PORTFOLIO and the EUROPEAN GROWTH
PORTFOLIO, in particular. Continued progress in the evolution of, for example, a
united European common market may be slowed by unanticipated political or social
events and may, therefore, adversely affect the value of certain of the
securities held by a Portfolio. Foreign companies are not subject to the
regulatory requirements of U.S. companies and, as such, there may be less
publicly available information about such companies. Moreover, foreign companies
are not subject to uniform accounting, auditing and financial reporting
standards and requirements comparable to those applicable to U.S. companies.
 
Securities of foreign issuers may be less liquid than comparable securities of
U.S. issuers and, as such, their price changes may be more volatile.
Furthermore, foreign exchanges and broker-dealers are generally subject to less
government and exchange scrutiny and regulation than their American
counterparts. Brokerage commissions, dealer concessions and other transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures on foreign markets may occasion delays in
settlements of Portfolio trades effected in such markets. Inability to dispose
of portfolio securities due to settlement delays could result in losses to a
Portfolio due to subsequent declines in value of such securities and the
inability of the Portfolio to make intended security purchases due to settlement
problems could result in a failure of the Portfolio to make potentially
advantageous investments. To the extent a Portfolio purchases Eurodollar
certificates of deposit issued by foreign branches of domestic United States
banks, consideration will be given to their domestic marketability, the lower
reserve requirements normally mandated for overseas banking operations, the
possible impact of interruptions in the flow of international currency
transactions, and future international political and economic developments which
might adversely affect the payment of principal or interest.
 
FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS. The GLOBAL DIVIDEND GROWTH
PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO and the
COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO may engage in transactions involving
forward foreign currency exchange contracts ("forward contracts"). A forward
contract involves an obligation to purchase or sell a currency at a future date,
which may be any fixed number of days from the date of the contract agreed upon
by the parties, at a price set at the time of the contract. The GLOBAL DIVIDEND
GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO
and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO may enter into forward contracts
as a hedge against fluctuations in future foreign exchange rates.
 
The Portfolios will enter into forward contracts under various circumstances.
When a Portfolio enters into a contract for the purchase or sale of a security
denominated in a foreign currency, it may, for example, desire to "lock in" the
price of the security in U.S. dollars or some other foreign currency which the
Portfolio is temporarily holding in its portfolio. By entering into a forward
contract for the purchase or sale, for a fixed amount of dollars or other
currency, of the amount of foreign currency involved in the underlying security
transactions, the Portfolio will be able to protect itself against a possible
loss resulting from an adverse change in the relationship between the U.S.
dollar or other currency which is being used for the security purchase and the
foreign currency in which the security is denominated during the period between
the date on which the security is purchased or sold and the date on which
payment is made or received.
 
At other times, when, for example, it is believed that the currency of a
particular foreign country may suffer a substantial decline against the U.S.
dollar or some other foreign currency, a Portfolio may enter into a forward
contract to sell, for a fixed amount of dollars or other currency, the amount of
foreign currency approximating the value of some or all of the Portfolio's
 
                                       32
<PAGE>
securities (or securities which the Portfolio has purchased for its portfolio)
denominated in such foreign currency. Under identical circumstances, the
Portfolio may enter into a forward contract to sell, for a fixed amount of U.S.
dollars or other currency, an amount of foreign currency other than the currency
in which the securities to be hedged are denominated approximating the value of
some or all of the portfolio securities to be hedged. This method of hedging,
called "cross-hedging," will be selected when it is determined that the foreign
currency in which the portfolio securities are denominated has insufficient
liquidity or is trading at a discount as compared with some other foreign
currency with which it tends to move in tandem.
 
In addition, when a Portfolio anticipates purchasing securities at some time in
the future, and wishes to lock in the current exchange rate of the currency in
which those securities are denominated against the U.S. dollar or some other
foreign currency, it may enter into a forward contract to purchase an amount of
currency equal to some or all of the value of the anticipated purchase, for a
fixed amount of U.S. dollars or other currency. The Portfolio may, however,
close out the forward contract without purchasing the security which was the
subject of the "anticipatory" hedge.
 
Lastly, the Portfolios are permitted to enter into forward contracts with
respect to currencies in which certain of their portfolio securities are
denominated and on which options have been written (see "Options and Futures
Transactions" below and in the Statement of Additional Information).
 
In all of the above circumstances, if the currency in which portfolio securities
(or anticipated portfolio securities) are denominated rises in value with
respect to the currency which is being purchased (or sold), then the Portfolio
will have realized fewer gains than had the Portfolio not entered into the
forward contracts. Moreover, the precise matching of the forward contract
amounts and the value of the securities involved will not generally be possible,
since the future value of such securities in foreign currencies will change as a
consequence of market movements in the value of those securities between the
date the forward contract is entered into and the date it matures. The GLOBAL
DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH
PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO are not required to
enter into such transactions with regard to their foreign currency-denominated
securities and will not do so unless deemed appropriate by the Investment
Manager or, in the case of the EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH
PORTFOLIO, the Sub-Adviser. The Portfolios generally will not enter into a
forward contract with a term of greater than one year, although they may enter
into forward contracts for periods of up to five years. The Portfolios may be
limited in their ability to enter into hedging transactions involving forward
contracts by the Internal Revenue Code requirements relating to qualifications
as a regulated investment company (see "Dividends, Distributions and Taxes").
 
AMERICAN DEPOSITORY RECEIPTS AND EUROPEAN DEPOSITORY RECEIPTS. The HIGH YIELD
PORTFOLIO, the UTILITIES PORTFOLIO, the INCOME BUILDER PORTFOLIO, the CAPITAL
GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH
PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO and the STRATEGIST PORTFOLIO may also invest in securities of foreign
issuers in the form of American Depository Receipts ("ADRs"), European
Depository Receipts ("EDRs") or other similar securities convertible into
securities of foreign issuers. In addition, the DIVIDEND GROWTH PORTFOLIO, the
CAPITAL APPRECIATION PORFOLIO, the EQUITY PORTFOLIO and the S&P 500 INDEX
PORTFOLIO may invest in ADRs. These securities may not necessarily be
denominated in the same currency as the securities into which they may be
converted. ADRs are receipts typically issued by a United States bank or trust
company evidencing ownership of the underlying securities. EDRs are European
receipts evidencing a similar arrangement. Generally, ADRs, in registered form,
are designed for use in the United States securities markets and EDRs, in bearer
form, are designed for use in European securities markets.
 
SECURITIES OF OTHER INVESTMENT COMPANIES. Each of the GLOBAL DIVIDEND GROWTH
PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO and the
CAPITAL APPRECIATION PORTFOLIO may invest up to 10% of its total assets in the
aggregate in shares of other investment companies and up to 5% of its total
assets in shares of any one investment company. A Portfolio may not own more
than 3% of the outstanding voting stock of any investment company. Such
investments may be the sole or most practical means by which the Portfolio may
participate in certain foreign securities markets. The Portfolio will incur any
indirect expenses incurred through investment in an investment company, such as
the payment of a management fee (which may result in the payment of an
additional advisory fee). Furthermore, it should be noted that foreign
investment companies are not subject to the U.S. securities laws and may be
subject to fewer or less stringent regulations than U.S. investment companies.
The S&P 500 INDEX PORTFOLIO may invest up to 10% of its total assets in the
aggregate in unit investment trusts holding a portfolio of securities linked to
the S&P 500 Index ("Standard & Poor's Depositary Receipts").
 
INVESTMENTS IN SECURITIES RATED BAA BY MOODY'S OR BBB BY S&P. The UTILITIES
PORTFOLIO, the DIVIDEND GROWTH PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the
GLOBAL DIVIDEND GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO and the
STRATEGIST PORTFOLIO may invest a portion of their assets in fixed-income
securities rated at the time of purchase Baa or better by Moody's Investors
Service, Inc. ("Moody's") or BBB or better by Standard & Poor's Corporation
("S&P"). Investments in fixed-income securities rated either Baa by Moody's or
BBB by S&P (the lowest credit ratings designated "investment grade") may have
speculative characteristics and, therefore, changes in economic conditions or
other circumstances are more likely to weaken their capacity to make principal
and interest payments than would be the case with investments in securities with
higher credit ratings. If a bond held by a Portfolio other than the CAPITAL
APPRECIATION PORTFOLIO is downgraded by a rating agency to a rating of below Baa
or BBB, the Portfolio will retain such security in its portfolio until the
Investment Manager determines that it is practicable to
 
                                       33
<PAGE>
sell the security without undue market or tax consequences to the Portfolio. In
the case of the CAPITAL APPRECIATION PORTFOLIO, the Portfolio may continue to
hold downgraded securities but will not purchase a non-investment grade debt
security if, immediately after such purchase, the Portfolio would have more than
5% of its total assets invested in such securities. The risks of holding
lower-rated securities are described below.
 
SPECIAL CONSIDERATIONS FOR INVESTMENTS IN HIGH YIELD SECURITIES. Because of the
special nature of the HIGH YIELD PORTFOLIO's, the INCOME BUILDER PORTFOLIO's and
the CAPITAL APPRECIATION PORTFOLIO's investments in lower rated, high yield
securities, commonly known as "junk bonds," the Investment Manager must take
account of certain special considerations in assessing the risks associated with
such investments. Although the growth of the high yield securities market in the
1980s had paralleled a long economic expansion, recently many issuers have been
affected by adverse economic and market conditions. It should be recognized that
an economic downturn or increase in interest rates is likely to have a negative
effect on the high yield bond market and on the value of the high yield
securities held by the Portfolios, as well as on the ability of the securities'
issuers to repay principal and interest on their borrowings.
 
The prices of high yield securities have been found to be less sensitive to
changes in prevailing interest rates than higher-rated investments, but are
likely to be more sensitive to adverse economic changes or individual corporate
developments. During an economic downturn or substantial period of rising
interest rates, highly leveraged issuers may experience financial stress which
would adversely affect their ability to service their principal and interest
payment obligations, to meet their projected business goals or to obtain
additional financing. If the issuer of a fixed-income security owned by a
Portfolio defaults, the Portfolio may incur additional expenses to seek
recovery. In addition, periods of economic uncertainty and change can be
expected to result in an increased volatility of market prices of high yield
securities and a concomitant volatility in the net asset value of a share of the
Portfolio. Moreover, the market prices of certain of the securities which are
structured as zero coupon and payment-in-kind securities are affected to a
greater extent by interest rate changes and thereby tend to be more volatile
than securities which pay interest periodically and in cash (see "Dividends,
Distributions and Taxes" for a discussion of the tax ramifications of
investments in such securities).
 
The secondary market for high yield securities may be less liquid than the
markets for higher quality securities and, as such, may have an adverse effect
on the market prices of certain securities. The illiquidity of the market may
also adversely affect the ability of the Fund's Trustees to arrive at a fair
value for certain high yield securities at certain times and could make it
difficult for the Portfolios to sell certain securities.
 
New laws and proposed new laws may have a potentially negative impact on the
market for high yield bonds. For example, present legislation requires
federally-insured savings and loan associations to divest their investments in
high yield bonds. This legislation and other proposed legislation may have an
adverse effect upon the value of high yield securities and a concomitant
negative impact upon the net asset value of a share of the HIGH YIELD PORTFOLIO,
the INCOME BUILDER PORTFOLIO and the CAPITAL APPRECIATION PORTFOLIO.
 
CONVERTIBLE SECURITIES. Each Portfolio (other than the MONEY MARKET PORTFOLIO,
the S&P 500 INDEX PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO) may
acquire through purchase, and each Portfolio (other than the MONEY MARKET
PORTFOLIO) may acquire through a distribution by the issuer of a security held
in its portfolio, a fixed-income security which is convertible into common stock
of the issuer. Convertible securities rank senior to common stocks in a
corporation's capital structure and, therefore, entail less risk than the
corporation's common stock. The value of a convertible security is a function of
its "investment value" (its value as if it did not have a conversion privilege),
and its "conversion value" (the security's worth if it were to be exchanged for
the underlying security, at market value, pursuant to its conversion privilege).
 
To the extent that a convertible security's investment value is greater than its
conversion value, its price will be primarily a reflection of such investment
value and its price will be likely to increase when interest rates fall and
decrease when interest rates rise, as with a fixed-income security (the credit
standing of the issuer and other factors may also have an effect on the
convertible security's value). If the conversion value exceeds the investment
value, the price of the convertible security will rise above its investment
value and, in addition, will sell at some premium over its conversion value.
(This premium represents the price investors are willing to pay for the
privilege of purchasing a fixed-income security with a possibility of capital
appreciation due to the conversion privilege). At such times the price of the
convertible security will tend to fluctuate directly with the price of the
underlying equity security.
 
A portion of the convertible securities in which each of these Portfolios may
invest are not rated. With the exception of securities purchased by the QUALITY
INCOME PLUS PORTFOLIO (which may not invest in securities rated lower than A by
Moody's or S&P at the time of purchase), when such securities are rated, such
ratings will generally be below investment grade. Securities below investment
grade are the equivalent of high yield, high risk bonds, commonly known as "junk
bonds." However, with the exception of the HIGH YIELD PORTFOLIO (which invests
primarily in lower-rated securities), no Portfolio will invest in convertible
securities that are in default in payment of principal or interest and each
Portfolio other than the HIGH YIELD PORTFOLIO and the INCOME BUILDER PORTFOLIO
has no current intention of investing in excess of 10% of its net assets in
unrated or lower-rated convertible securities. The risks of holding lower-rated
securities are described above.
 
The INCOME BUILDER PORTFOLIO may invest up to 25% of its total assets in
"enhanced" convertible securities. Enhanced convertible securities offer holders
the opportunity to obtain higher current income than would be available from a
traditional
 
                                       34
<PAGE>
equity security issued by the same company, in return for reduced participation
or a cap on appreciation in the underlying common stock of the issuer which the
holder can realize. In addition, in many cases, enhanced convertible securities
are convertible into the underlying common stock of the issuer automatically at
maturity, unlike traditional convertible securities which are convertible only
at the option of the security holder. Enhanced convertible securities may be
more volatile than traditional convertible securities due to the mandatory
conversion feature.
 
The INCOME BUILDER PORTFOLIO also may invest up to 10% of its total assets in
"synthetic" convertible securities. Unlike traditional convertible securities
whose conversion values are based on the common stock of the issuer of the
convertible security, "synthetic" convertible securities are preferred stocks or
debt obligations of an issuer which are combined with an equity component whose
conversion value is based on the value of the common stock of a different issuer
or a particular benchmark (which may include a foreign issuer or basket of
foreign stocks, or a company whose stock is not yet publicly traded). In many
cases, "synthetic" convertible securities are not convertible prior to maturity,
at which time the value of the security is paid in cash by the issuer.
 
"Synthetic" convertible securities may be less liquid than traditional
convertible securities and their price changes may be more volatile. Reduced
liquidity may have an adverse impact on the ability of the INCOME BUILDER
PORTFOLIO to sell particular synthetic securities promptly at favorable prices
and may also make it more difficult for the Portfolio to obtain market
quotations based on actual trades, for purposes of valuing the portfolio
securities of the INCOME BUILDER PORTFOLIO.
 
The INCOME BUILDER PORTFOLIO may invest without limitation in "exchangeable"
convertible bonds and convertible preferred stock which are issued by one
company, but convertible into the common stock of a different publicly traded
company. These securities generally have liquidity trading and risk
characteristics similar to traditional convertible securities noted above.
 
REAL ESTATE INVESTMENT TRUSTS. Each of the UTILITIES PORTFOLIO, the INCOME
BUILDER PORTFOLIO, the DIVIDEND GROWTH PORTFOLIO, the CAPITAL GROWTH PORTFOLIO,
the GLOBAL DIVIDEND GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the
EQUITY PORTFOLIO and the STRATEGIST PORTFOLIO may invest in real estate
investment trusts, which pool investors' funds for investments primarily in
commercial real estate properties. Investment in real estate investment trusts
may be the most practical available means for the Portfolios to invest in the
real estate industry (the Portfolios are prohibited from investing in real
estate directly). As a shareholder in a real estate investment trust, the
Portfolio would bear its ratable share of the real estate investment trust's
expenses, including its advisory and administration fees. At the same time the
Portfolio would continue to pay its own investment management fees and other
expenses, as a result of which the Portfolio and its shareholders in effect will
be absorbing duplicate levels of fees with respect to investments in real estate
investment trusts. Real estate investment trusts are not diversified and are
subject to the risk of financing projects. They are also subject to heavy cash
flow dependency, defaults by borrowers or tenants, self-liquidation, and the
possibility of failing to qualify for tax-free status under the Internal Revenue
Code and failing to maintain exemption from the Investment Company Act of 1940,
as amended.
 
LENDING OF PORTFOLIO SECURITIES. Consistent with applicable regulatory
requirements, each Portfolio of the Fund may lend its portfolio securities to
brokers, dealers and other financial institutions, provided that such loans are
callable at any time by the Portfolio (subject to certain notice provisions
described in the Statement of Additional Information), and are at all times
secured by cash or money market instruments, which are maintained in a
segregated account pursuant to applicable regulations and that are equal to at
least the market value, determined daily, of the loaned securities. As with any
extensions of credit, there are risks of delay in recovery and in some cases
even loss of rights in the collateral should the borrower of the securities fail
financially. However, loans of portfolio securities will only be made to firms
deemed by the Investment Manager or, in the case of the EUROPEAN GROWTH
PORTFOLIO and the PACIFIC GROWTH PORTFOLIO, the Sub-Adviser to be creditworthy
and when the income which can be earned from such loans justifies the attendant
risks.
 
REPURCHASE AGREEMENTS. Each Portfolio of the Fund may enter into repurchase
agreements, which may be viewed as a type of secured lending by the Portfolio,
and which typically involve the acquisition by the Portfolio of debt securities
from a selling financial institution such as a bank, savings and loan
association or broker-dealer. The agreement provides that the Portfolio will
sell back to the institution, and that the institution will repurchase, the
underlying security ("collateral") at a specified price and at a fixed time in
the future, usually not more than seven days from the date of purchase. The
Portfolio will receive interest from the institution until the time when the
repurchase is to occur. Although such date is deemed by the Portfolio to be the
maturity date of a repurchase agreement, the maturities of securities subject to
repurchase agreements are not subject to any limits and may exceed one year.
While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. These procedures include effecting repurchase transactions only with
large, well-capitalized and well-established financial institutions and
specifying the required value of the collateral underlying the agreement.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS. From time
to time, in the ordinary course of business, each Portfolio of the Fund other
than the S&P 500 INDEX PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO
may purchase securities on a when-issued or delayed delivery basis or may
purchase or sell securities on a forward commitment basis. When such
transactions are negotiated, the price is fixed at the time of the commitment,
but delivery and payment can take place a month or more after the date of the
 
                                       35
<PAGE>
commitment. While a Portfolio will only purchase securities on a when-issued,
delayed delivery or forward commitment basis with the intention of acquiring the
securities, a Portfolio may sell the securities before the settlement date, if
it is deemed advisable. The securities so purchased or sold are subject to
market fluctuation and no interest accrues to the purchaser during this period.
At the time a Portfolio makes the commitment to purchase or sell securities on a
when-issued, delayed delivery or forward commitment basis, it will record the
transaction and thereafter reflect the value, each day, of such security
purchased or, if a sale, the proceeds to be received, in determining its net
asset value. At the time of delivery of the securities, their value may be more
or less than the purchase or sale price. A Portfolio will also establish a
segregated account with its custodian bank in which it will continually maintain
cash or cash equivalents or other high grade debt portfolio securities equal in
value to commitments to purchase securities on a when-issued, delayed delivery
or forward commitment basis. An increase in the percentage of a Portfolio's
assets committed to the purchase of securities on a when-issued, delayed
delivery or forward commitment basis may increase the volatility of the
Portfolio's net asset value.
 
WHEN, AS AND IF ISSUED SECURITIES. Each Portfolio (other than the MONEY MARKET
PORTFOLIO, the S&P 500 INDEX PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO) may purchase securities on a "when, as and if issued" basis under
which the issuance of the security depends upon the occurrence of a subsequent
event, such as approval of a merger, corporate reorganization or debt
restructuring. The commitment for the purchase of any such security will not be
recognized in the portfolio until the Investment Manager determines that the
issuance of the security is probable, whereupon the accounting treatment for
such commitment will be the same as for a commitment to purchase a security on a
when-issued, delayed delivery or forward commitment basis, described above and
in the Statement of Additional Information. An increase in the percentage of a
Portfolio's assets committed to the purchase of securities on a "when, as and if
issued" basis may increase the volatility of its net asset value.
 
PRIVATE PLACEMENTS. As a fundamental policy, which may be changed only by the
shareholders of the affected Portfolios, each of the QUALITY INCOME PLUS
PORTFOLIO, the DIVIDEND GROWTH PORTFOLIO, the EQUITY PORTFOLIO and the
STRATEGIST PORTFOLIO may invest up to 5% of its total assets in securities which
are subject to restrictions on resale because they have not been registered
under the Securities Act of 1933, as amended (the "Securities Act"), or which
are otherwise not readily marketable. These securities are generally referred to
as private placements or restricted securities. Limitations on the resale of
such securities may have an adverse effect on their marketability, and may
prevent the Portfolio from disposing of them promptly at reasonable prices. The
Portfolio may have to bear the expense of registering such securities for resale
and the risk of substantial delays in effecting such registration.
 
As a non-fundamental policy, which may be changed by the Trustees of the Fund,
each of the UTILITIES PORTFOLIO, the INCOME BUILDER PORTFOLIO, the CAPITAL
GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO and the CAPITAL
APPRECIATION PORTFOLIO may invest up to 5%, the EUROPEAN GROWTH PORTFOLIO may
invest up to 10%, and each of the HIGH YIELD PORTFOLIO, the PACIFIC GROWTH
PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO may invest up to 15%,
of its total assets in private placements or restricted securities. (With regard
to these nine Portfolios, securities eligible for resale pursuant to Rule 144A
under the Securities Act, and determined to be liquid pursuant to the procedures
discussed in the following paragraph, are not subject to the foregoing
restriction.)
 
The Securities and Exchange Commission has adopted Rule 144A under the
Securities Act, which permits the thirteen Portfolios named above to sell
restricted securities to qualified institutional buyers without limitation. The
Investment Manager, pursuant to procedures adopted by the Trustees of the Fund,
will make a determination as to the liquidity of each restricted security
purchased by any of these Portfolios. If a restricted security is determined to
be "liquid," such security will not be included within the category "illiquid
securities," which is limited by the Fund's investment restrictions to 10% of
the total assets of each of these Portfolios other than the HIGH YIELD
PORTFOLIO, the INCOME BUILDER PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO,
the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO and the
COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO, and which under current policy is
limited to 15% of the net assets of each of the five Portfolios named above.
 
ZERO COUPON SECURITIES. A portion of the fixed-income purchased by each
Portfolio may be zero coupon securities. Such securities are purchased at a
discount from their face amount, giving the purchaser the right to receive their
full value at maturity. The interest earned on such securities is, implicitly,
automatically compounded and paid out at maturity. While such compounding at a
constant rate eliminates the risk of receiving lower yields upon reinvestment of
interest if prevailing interest rates decline, the owner of a zero coupon
security will be unable to participate in higher yields upon reinvestment of
interest received on interest-paying securities if prevailing interest rates
rise.
 
A zero coupon security pays no interest to its holder during its life.
Therefore, to the extent a Portfolio invests in zero coupon securities, it will
not receive current cash available for distribution to shareholders. In
addition, zero coupon securities are subject to substantially greater price
fluctuations during periods of changing prevailing interest rates than are
comparable securities which pay interest on a current basis. Current federal tax
law requires that a holder (such as a Portfolio) of a zero coupon security
accrue a portion of the discount at which the security was purchased as income
each year even though the Portfolio receives no interest payments in cash on the
security during the year.
 
WARRANTS. Each Portfolio (other than the MONEY MARKET PORTFOLIO and the QUALITY
INCOME PLUS PORTFOLIO) may acquire warrants
 
                                       36
<PAGE>
attached to other securities. In addition, each of the INCOME BUILDER PORTFOLIO,
the DIVIDEND GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the
EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the CAPITAL
APPRECIATION PORTFOLIO, the EQUITY PORTFOLIO and the STRATEGIST PORTFOLIO may
invest in warrants not attached to other securities, provided that each of the
DIVIDEND GROWTH PORTFOLIO and the EQUITY PORTFOLIO may only invest up to 5% of
the value of its total assets in warrants not attached to other securities,
including up to 2% of such assets in warrants not listed on either the New York
or American Stock Exchange. In addition, the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO may invest in warrants which are issued as a distribution by the
issuer or a security held in its portfolio. Warrants are, in effect, an option
to purchase equity securities at a specific price, generally valid for a
specific period of time, and have no voting rights, pay no dividends and have no
rights with respect to the corporation issuing them. If warrants remain
unexercised at the end of the exercise period, they will lapse and the
Portfolio's investment in them will be lost. The prices of warrants do not
necessarily move parallel to the prices of the underlying securities.
 
OPTIONS AND FUTURES TRANSACTIONS
 
As noted above, each of the QUALITY INCOME PLUS PORTFOLIO, the UTILITIES
PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO,
the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the CAPITAL
APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the
STRATEGIST PORTFOLIO may write covered call options against securities held in
its portfolio and covered put options on eligible portfolio securities (the
UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH
PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO and the STRATEGIST PORTFOLIO may also write covered put and call
options on stock indexes) and purchase options of the same or similar series to
effect closing transactions, and may hedge against potential changes in the
market value of its investments (or anticipated investments) by purchasing put
and call options on securities which it holds (or has the right to acquire) in
its portfolio and engaging in transactions involving interest rate futures
contracts and bond index futures contracts and options on such contracts. The
UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH
PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the
CAPITAL APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and
the STRATEGIST PORTFOLIO may also hedge against such changes by entering into
transactions involving stock index futures contracts and options thereon, and
(except for the EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH PORTFOLIO)
options on stock indexes. The GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN
GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION
PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO may also hedge against
potential changes in the market value of the currencies in which their
investments (or anticipated investments) are denominated by writing and/or
purchasing put and call options on currencies and engaging in transactions
involving currencies futures contracts and options on such contracts. The S&P
500 INDEX PORTFOLIO may purchase and sell stock index futures contracts that are
traded on U.S. commodity exchanges on the S&P 500 Index.
 
Call and put options on U.S. Treasury notes, bonds and bills, on various foreign
currencies and on equity securities are listed on Exchanges and are written in
over-the-counter transactions ("OTC options"). Listed options are issued or
guaranteed by the exchange on which they trade or by a clearing corporation such
as the Options Clearing Corporation ("OCC"). Ownership of a listed call option
gives the Portfolio the right to buy from the OCC (in the U.S.) or other
clearing corporation or exchange the underlying security covered by the option
at the stated exercise price (the price per unit of the underlying security) by
filing an exercise notice prior to the expiration of the option. The writer
(seller) of the option would then have the obligation to sell to the OCC (in the
U.S.) or other clearing corporation or exchange the underlying security at that
exercise price prior to the expiration date of the option, regardless of its
then current market price. Ownership of a listed put option would give the
Portfolio the right to sell the underlying security to the OCC (in the U.S.) or
other clearing corporation or exchange at the stated exercise price. Upon notice
of exercise of the put option, the writer of the put would have the obligation
to purchase the underlying security from the OCC (in the U.S.) or other clearing
corporation or exchange at the exercise price.
 
Exchange-listed options are issued by the OCC (in the U.S.) or other clearing
corporation or exchange which assures that all transactions in such options are
properly executed. OTC options are purchased from or sold (written) to dealers
or financial institutions which have entered into direct agreements with the
Portfolio. With OTC options, such variables as expiration date, exercise price
and premium will be agreed upon between the Portfolio and the transacting
dealer, without the intermediation of a third party such as the OCC. If the
transacting dealer fails to make or take delivery of the securities (or, in the
case of the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the
PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO or the COMPETITIVE
EDGE "BEST IDEAS" PORTFOLIO, the currency) underlying an option it has written,
in accordance with the terms of that option, the Portfolio would lose the
premium paid for the option as well as any anticipated benefit of the
transaction. The Portfolios will engage in OTC option transactions only with
member banks of the Federal Reserve System or primary dealers in U.S. Government
securities or with affiliates of such banks or dealers which have capital of at
least $50 million or whose obligations are guaranteed by an entity having
capital of at least $50 million.
 
COVERED CALL WRITING. The QUALITY INCOME PLUS PORTFOLIO, the UTILITIES
PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO,
the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the CAPITAL
APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the
STRATEGIST PORTFOLIO are permitted to write covered call options on portfolio
securities, without limit, in order to aid them in achieving their investment
objectives. In the case of the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN
GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION
PORTFOLIO and the COMPETITIVE EDGE "BEST
 
                                       37
<PAGE>
IDEAS" PORTFOLIO, such options may be denominated in either U.S. dollars or
foreign currencies and may be on the U.S. dollar and foreign currencies. As a
writer of a call option, the Portfolio has the obligation, upon notice of
exercise of the option, to deliver the security (or amount of currency)
underlying the option prior to the expiration date of the option (certain listed
and OTC put options written by a Portfolio will be exercisable by the purchaser
only on a specific date).
 
COVERED PUT WRITING. As a writer of covered put options, the QUALITY INCOME PLUS
PORTFOLIO, the UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL
DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH
PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO or the STRATEGIST PORTFOLIO incurs an obligation to buy the security
underlying the option from the purchaser of the put, at the option's exercise
price at any time during the option period, at the purchaser's election (certain
listed and OTC put options written by a Portfolio will be exercisable by the
purchaser only on a specific date). The QUALITY INCOME PLUS PORTFOLIO, the
UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH
PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the
CAPITAL APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and
the STRATEGIST PORTFOLIO will write put options for two purposes: (1) to receive
the income derived from the premiums paid by purchasers; and (2) when the
Portfolio's management wishes to purchase the security underlying the option at
a price lower than its current market price, in which case the Portfolio will
write the covered put at an exercise price reflecting the lower purchase price
sought. The aggregate value of the obligations underlying the puts determined as
of the date the options are sold will not exceed 50% of a Portfolio's net
assets.
 
PURCHASING CALL AND PUT OPTIONS. The QUALITY INCOME PLUS PORTFOLIO may purchase
listed and OTC call and put options in amounts equalling up to 10% of its total
assets. Each of the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH
PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the
CAPITAL APPRECIATION PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO
may purchase such call and put options in amounts equalling up to 5% of its
total assets. Each of the UTILITIES PORTFOLIO, the GLOBAL DIVIDEND GROWTH
PORTFOLIO and the STRATEGIST PORTFOLIO may purchase such call and put options
and options on stock indexes in amounts equalling up to 10% of its total assets,
with a maximum of 5% of its total assets invested in the purchase of stock index
options. These Portfolios may purchase call options either to close out a
covered call position or to protect against an increase in the price of a
security a Portfolio anticipates purchasing or, in the case of call options on a
foreign currency, to hedge against an adverse exchange rate change of the
currency in which the security the GLOBAL DIVIDEND GROWTH PORTFOLIO, the
EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the CAPITAL
APPRECIATION PORTFOLIO or the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO
anticipates purchasing is denominated vis-a-vis the currency in which the
exercise price is denominated. The Portfolio may purchase put options on
securities which it holds (or has the right to acquire) in its portfolio only to
protect itself against a decline in the value of the security. Similarly, each
of the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the
PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO or the COMPETITIVE
EDGE "BEST IDEAS" PORTFOLIO may purchase put options on currencies in which
securities it holds are denominated only to protect itself against a decline in
value of such currency vis-a-vis the currency in which the exercise price is
denominated. The Portfolios may also purchase put options to close out written
put positions in a manner similar to call option closing purchase transactions.
There are no other limits on the ability of these Portfolios to purchase call
and put options.
 
STOCK INDEX OPTIONS. The UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the
GLOBAL DIVIDEND GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the
COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the STRATEGIST PORTFOLIO may invest
in options on stock indexes, which are similar to options on stock except that,
rather than the right to take or make delivery of stock at a specified price, an
option on a stock index gives the holder the right to receive, upon exercise of
the option, an amount of cash if the closing level of the stock index upon which
the option is based is greater than, in the case of a call, or lesser than, in
the case of a put, the exercise price of the option. See "Risks of Options on
Indexes," in the Statement of Additional Information.
 
FUTURES CONTRACTS. The QUALITY INCOME PLUS PORTFOLIO, the UTILITIES PORTFOLIO,
the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN
GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION
PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the STRATEGIST
PORTFOLIO may purchase and sell interest rate futures contracts that are
currently traded, or may in the future be traded, on U.S. commodity exchanges on
such underlying securities as U.S. Treasury bonds, notes, and bills and GNMA
Certificates and bond index futures contracts that are traded on U.S. commodity
exchanges on such indexes as the Moody's Investment-Grade Corporate Bond Index.
The UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND
GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO,
the CAPITAL APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO
and the STRATEGIST PORTFOLIO may also purchase and sell stock index futures
contracts that are currently traded, or may in the future be traded, on U.S.
commodity exchanges on such indexes as the S&P 500 Index and the New York Stock
Exchange Composite Index. The S&P 500 INDEX PORTFOLIO may invest in stock index
futures contracts that are traded on U.S. commodity exchanges on the S&P 500
Index. The GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the
PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO and the COMPETITIVE
EDGE "BEST IDEAS" PORTFOLIO may also purchase and sell futures contracts that
are currently traded, or may in the future be traded, on foreign commodity
exchanges on such underlying securities as common stocks or any foreign
government fixed-income security, on various currencies ("currency futures") and
on such indexes of foreign equity and fixed-income securities as may exist or
come into being, such as the Financial Times Equity Index. As a futures contract
purchaser, a Portfolio incurs an obligation to take delivery of a specified
amount of the obligation underlying the contract at a specified time in the
future for a
 
                                       38
<PAGE>
specified price. As a seller of a futures contract, a Portfolio incurs an
obligation to deliver the specified amount of the underlying obligation at a
specified time in return for an agreed upon price.
 
The QUALITY INCOME PLUS PORTFOLIO, the UTILITIES PORTFOLIO, the CAPITAL GROWTH
PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO,
the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the
COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the STRATEGIST PORTFOLIO will
purchase or sell interest rate futures contracts and bond index futures
contracts for the purpose of hedging their fixed-income portfolio (or
anticipated portfolio) securities against changes in prevailing interest rates
or, in the case of the UTILITIES PORTFOLIO and the STRATEGIST PORTFOLIO, to
facilitate asset reallocations into and out of the fixed-income area. The
UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH
PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the
CAPITAL APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and
the STRATEGIST PORTFOLIO will purchase or sell stock index futures contracts for
the purpose of hedging their equity portfolio (or anticipated portfolio)
securities against changes in their prices or, in the case of the UTILITIES
PORTFOLIO and the STRATEGIST PORTFOLIO, to facilitate asset reallocations into
and out of the equity area. The GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN
GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION
PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO will purchase or sell
currency futures on currencies in which their portfolio securities (or
anticipated portfolio securities) are denominated for the purposes of hedging
against anticipated changes in currency exchange rates. The S&P 500 INDEX
PORTFOLIO may purchase and sell stock index futures contracts that are traded on
U.S. commodity exchanges on the S&P 500 Index, for the following reasons: to
simulate full investment in the S&P 500 Index while retaining a cash balance for
portfolio management purposes, to facilitate trading, to reduce transaction
costs or to seek higher investment returns when a futures contracts is priced
more attractively than stocks comprising the S&P 500 Index.
 
OPTIONS ON FUTURES CONTRACTS. The QUALITY INCOME PLUS PORTFOLIO, the UTILITIES
PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO,
the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the CAPITAL
APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the
STRATEGIST PORTFOLIO may purchase and write call and put options on futures
contracts which are traded on an exchange and enter into closing transactions
with respect to such options to terminate an existing position. An option on a
futures contract gives the purchaser the right, in return for the premium paid,
to assume a position in a futures contract (a long position if the option is a
call and a short position if the option is a put) at a specified exercise price
at any time during the term of the option. The QUALITY INCOME PLUS PORTFOLIO,
the UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL DIVIDEND
GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO,
the CAPITAL APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO
and the STRATEGIST PORTFOLIO will only purchase and write options on futures
contracts for identical purposes to those set forth above for the purchase of a
futures contract (purchase of a call option or sale of a put option) and the
sale of a futures contract (purchase of a put option or sale of a call option),
or to close out a long or short position in futures contracts.
 
RISKS OF OPTIONS AND FUTURES TRANSACTIONS. A Portfolio may close out its
position as writer of an option, or as a buyer or seller of a futures contract,
only if a liquid secondary market exists for options or futures contracts of
that series. There is no assurance that such a market will exist, particularly
in the case of OTC options, as such options will generally only be closed out by
entering into a closing purchase transaction with the purchasing dealer. Also,
exchanges limit the amount by which the price of a futures contract may move on
any day. If the price moves equal the daily limit on successive days, then it
may prove impossible to liquidate a futures position until the daily limit moves
have ceased.
 
While the futures contracts and options transactions to be engaged in by the
QUALITY INCOME PLUS PORTFOLIO, the UTILITIES PORTFOLIO, the CAPITAL GROWTH
PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO,
the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the S&P 500
INDEX PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the STRATEGIST
PORTFOLIO for the purpose of hedging their portfolio securities are not
speculative in nature, there are risks inherent in the use of such instruments.
One such risk is that the Portfolio's management could be incorrect in its
expectations as to the direction or extent of various interest rate movements or
the time span within which the movements take place. For example, if a Portfolio
sold interest rate futures contracts for the sale of securities in anticipation
of an increase in interest rates, and then interest rates went down instead,
causing bond prices to rise, the Portfolio would lose money on the sale.
 
Another risk which may arise in employing futures contracts to protect against
the price volatility of portfolio securities is that the prices of securities,
currencies and indexes subject to futures contracts (and thereby the futures
contract prices) may correlate imperfectly with the behavior of the U.S. dollar
cash prices of the portfolio securities (and, in the case of the GLOBAL DIVIDEND
GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO,
the CAPITAL APPRECIATION PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO, the securities' denominated currencies). Another such risk is that
prices of interest rate futures contracts may not move in tandem with the
changes in prevailing interest rates against which the Portfolio seeks a hedge.
A correlation may also be distorted by the fact that the futures market is
dominated by short-term traders seeking to profit from the difference between a
contract or security price objective and their cost of borrowed funds. Such
distortions are generally minor and would diminish as the contract approached
maturity.
 
The GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC
GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO and the COMPETITIVE EDGE
"BEST IDEAS" PORTFOLIO, by entering into transactions in foreign futures and
options markets, will incur risks similar to those discussed above under
"Foreign Securities."

New options and futures contracts and other financial products and various
combinations thereof continue to be developed. The QUALITY INCOME PLUS
PORTFOLIO, the UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL
DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH
PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO and the STRATEGIST PORTFOLIO may invest in any such options, futures
and products as may be developed to the extent consistent with their investment
objectives and applicable regulatory requirements, and the Fund will make any
and all pertinent disclosures relating to such investments in its Prospectus
and/or Statement of Additional Information. Except as otherwise noted above,
there are no limitations on the ability of any of these Portfolios to invest in
options, futures and options on futures.
 
PORTFOLIO TRADING
 
Although the Fund does not intend to engage in short-term trading of portfolio
securities as a means of achieving the investment objectives of the respective
Portfolios, each Portfolio may sell portfolio securities without regard to the
length of time they have been held whenever such sale will in the opinion of the
Investment Manager (or, in the case of the EUROPEAN GROWTH PORTFOLIO and the
PACIFIC GROWTH PORTFOLIO, the Sub-Adviser) strengthen the Portfolio's position
and contribute to its investment objectives. In determining which securities to
purchase for the Portfolios or hold in a Portfolio, the Investment Manager and,
in the case of the EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH PORTFOLIO,
the Sub-Adviser will rely on information from various sources, including
research, analysis and appraisals of brokers and dealers, the views of Trustees
of the Fund and others regarding economic developments and interest rate trends,
and the Investment Manager's and, in the case of the EUROPEAN GROWTH PORTFOLIO
and the PACIFIC GROWTH PORTFOLIO, the Sub-Adviser's own analysis of factors they
deem relevant.
 
Personnel of the Investment Manager and, in the case of the EUROPEAN GROWTH
PORTFOLIO and the PACIFIC GROWTH PORTFOLIO, the Sub-Adviser have substantial
experience in the use of the investment techniques described above under the
heading "Options and Futures Transactions," which techniques require skills
different from those needed to select the portfolio securities underlying
various options and futures contracts.
 
Brokerage commissions are not normally charged on the purchase or sale of money
market instruments and U.S. Government obligations, or on currency conversions,
but such transactions will involve costs in the form of spreads between bid and
asked prices. Orders for transactions in portfolio securities and commodities
may be placed for the Fund with a number of brokers and dealers, including Dean
Witter Reynolds Inc. ("DWR"), the principal underwriter of certain of the
Variable Annuity Contracts and the Variable Life Contracts, Morgan Stanley & Co.
Incorporated ("Morgan Stanley") and other broker-dealer affiliates of
InterCapital, and certain affiliated broker-dealers of Morgan Grenfell
Investment Services Limited, the Sub-Adviser of the EUROPEAN GROWTH PORTFOLIO
and the PACIFIC GROWTH PORTFOLIO. Pursuant to an order of the Securities and
Exchange Commission, the Fund may effect principal transactions in certain money
market instruments with DWR. In addition, the Fund may incur brokerage
commissions on transactions conducted through DWR, Morgan Stanley and other
affiliated broker-dealers of InterCapital and affiliated broker-dealers of the
Sub-Adviser of the EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH PORTFOLIO.
Substantially all of the orders for transactions in portfolio securities and
commodities listed on exchanges are expected to be placed for the COMPETITIVE
EDGE "BEST IDEAS" PORTFOLIO with broker-dealers affiliated with InterCapital,
including DWR and Morgan Stanley. Transactions effected through such affiliated
broker-dealers are effected pursuant to procedures adopted by the Fund's Board
of Trustees that are designed to ensure that the commissions paid to such
affiliated broker-dealers are not more than the commissions expected to be paid
to unaffiliated brokers or dealers in a commensurate arms-length transaction.
 
The Money Market Portfolio is expected to have a high portfolio turnover due to
the short maturities of securities purchased, but this should not affect income
or net asset value as brokerage commissions are not normally charged on the
purchase or sale of money market instruments. It is not anticipated that the
portfolio turnover rates of the Portfolios will exceed the following percentages
in any year: QUALITY INCOME PLUS PORTFOLIO: 300%; HIGH YIELD PORTFOLIO: 300%;
UTILITIES PORTFOLIO: 100%; DIVIDEND GROWTH PORTFOLIO: 90%; INCOME BUILDER
PORTFOLIO: 90%; CAPITAL GROWTH PORTFOLIO: 200%; GLOBAL DIVIDEND GROWTH
PORTFOLIO: 100%; EUROPEAN GROWTH PORTFOLIO: 100%; PACIFIC GROWTH PORTFOLIO:
100%; CAPITAL APPRECIATION PORTFOLIO: 300%; EQUITY PORTFOLIO: 300%; S&P 500
INDEX PORTFOLIO: 100%; COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO: 100%; and
STRATEGIST PORTFOLIO: 400%. A portfolio turnover rate exceeding 100% in any one
year is greater than that of many other investment companies. Each Portfolio of
the Fund will incur underwriting discount costs (on underwritten securities)
and/or brokerage costs commensurate with its portfolio turnover rate. The
expenses of the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO
and the PACIFIC GROWTH PORTFOLIO relating to their portfolio management are
likely to be greater than those incurred by other investment companies investing
primarily in securities issued by domestic issuers as custodial costs, brokerage
commissions and other transaction charges related to investing in foreign
markets are generally higher than in the United States. Short-term gains and
losses may result from portfolio transactions. See "Dividends, Distributions and
Taxes" for a discussion of the tax implications of the Portfolios' trading
policies. A more extensive discussion of the Portfolios' brokerage policies is
set forth in the Statement of Additional Information.

INVESTMENT RESTRICTIONS
- ----------------------------------------------------------
 
The investment restrictions listed below are among the restrictions that have
been adopted by the Fund as fundamental policies of each Portfolio. Under the
Investment Company Act of 1940, as amended (the "Act"), a fundamental policy may
not be changed with respect to a Portfolio without the vote of a majority of the
outstanding voting securities of that Portfolio, as defined in the Act.
 
Each Portfolio of the Fund may not:
 
    1.  Invest more than 5% of the value of its total assets in the securities
of any one issuer (other than obligations issued or guaranteed by the United
States Government, its agencies or instrumentalities), or purchase more than 10%
of the voting securities, or more than 10% of any class of security, of any
issuer (for this purpose all outstanding debt securities of an issuer are
considered as one class and all preferred stock of an issuer are considered as
one class). With regard to the INCOME BUILDER PORTFOLIO, the CAPITAL GROWTH
PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO,
the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the S&P 500
INDEX PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO, these
limitations apply only as to 75% of the Portfolio's total assets.
 
    2.  Concentrate its investments in any particular industry, but if deemed
appropriate for attainment of its investment objective, a Portfolio may invest
up to 25% of its total assets (valued at the time of investment) in any one
industry classification used by that Portfolio for investment purposes. This
restriction does not apply to obligations issued or guaranteed by the United
States Government or its agencies or instrumentalities, or, in the case of the
MONEY MARKET PORTFOLIO, to domestic bank obligations (not including obligations
issued by foreign branches of such banks) or, in the case of the UTILITIES
PORTFOLIO, to the utilities industry, in which industry the Portfolio will
concentrate.
 
    3.  Invest more than 5% of the value of its total assets in securities of
issuers having a record, together with predecessors, of less than three years of
continuous operation. This restriction shall not apply to any obligation issued
or guaranteed by the United States Government, its agencies or
instrumentalities.
 
    4.  Purchase or sell commodities or commodity futures contracts, or oil, gas
or mineral exploration or developmental programs, except that a Portfolio may
invest in the securities of companies which operate, invest in, or sponsor such
programs, and (i) the QUALITY INCOME PLUS PORTFOLIO, the UTILITIES PORTFOLIO,
the INCOME BUILDER PORTFOLIO, the DIVIDEND GROWTH PORTFOLIO, the CAPITAL GROWTH
PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO,
the PACIFIC GROWTH PORTFOLIO, the CAPITAL APRECIATION PORTFOLIO, the COMPETITIVE
EDGE "BEST IDEAS" PORTFOLIO and the STRATEGIST PORTFOLIO may purchase or sell
futures contracts and related options thereon, (ii) the GLOBAL DIVIDEND GROWTH
PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC
 
                                       41
<PAGE>
GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO and the COMPETITIVE EDGE
"BEST IDEAS" PORTFOLIO may purchase or sell currency futures contracts and
related options thereon and the S&P 500 INDEX PORTFOLIO may purchase or sell
index futures contracts.
 
    5.  Borrow money (except insofar as the EUROPEAN GROWTH PORTFOLIO and the
PACIFIC GROWTH PORTFOLIO may be deemed to have borrowed by entrance into a
reverse repurchase agreement up to an amount not exceeding 10% of the
Portfolio's total assets), except from banks for temporary or emergency purposes
or to meet redemption requests which might otherwise require the untimely
disposition of securities, and, in the case of the Portfolios other than the
QUALITY INCOME PLUS PORTFOLIO, not for investment or leveraging, provided that
borrowing in the aggregate (other than, in the case of the QUALITY INCOME PLUS
PORTFOLIO, for investment or leveraging) may not exceed 5% of the value of the
Portfolio's total assets (including the amount borrowed) at the time of such
borrowing.
 
    6.  Pledge its assets or assign or otherwise encumber them except to secure
permitted borrowings. (For the purpose of this restriction, collateral
arrangements with respect to the writing of options and collateral arrangements
with respect to initial margin for futures are not deemed to be pledges of
assets.)
 
    7.  Purchase securities on margin (but the Portfolios may obtain short-term
loans as are necessary for the clearance of transactions). The deposit or
payment by the QUALITY INCOME PLUS PORTFOLIO, the UTILITIES PORTFOLIO, the
INCOME BUILDER PORTFOLIO, the DIVIDEND GROWTH PORTFOLIO, the CAPITAL GROWTH
PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO,
the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the S&P 500
INDEX PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the STRATEGIST
PORTFOLIO of initial or variation margin in connection with futures contracts or
related options thereon is not considered the purchase of a security on margin.
 
    8.  In the case of each Portfolio other than the S&P 500 INDEX PORTFOLIO and
the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO, purchase securities of other
investment companies, except in connection with a merger, consolidation,
reorganization or acquisition of assets or, in the case of the GLOBAL DIVIDEND
GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO
and the CAPITAL APPRECIATION PORTFOLIO, in accordance with the provisions of
Section 12(d) of the Act and any Rules promulgated thereunder (E.G., each of
these Portfolios may not invest in more than 3% of the outstanding voting
securities of any investment company).
 
Each of the QUALITY INCOME PLUS PORTFOLIO, the DIVIDEND GROWTH PORTFOLIO, the
EQUITY PORTFOLIO and the STRATEGIST PORTFOLIO may not invest more than 5% of the
value of its total assets in securities which are restricted as to disposition
under the Federal securities laws or otherwise, provided that this restriction
shall not apply to securities received as a result of a corporate reorganization
or similar transaction affecting readily marketable securities already held by
the Portfolio; however, these Portfolios will attempt to dispose in an orderly
fashion of any securities received under these circumstances to the extent that
such securities, together with other illiquid securities, exceed 10% of the
Portfolio's total assets.
 
Each of the UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO and the EUROPEAN
GROWTH PORTFOLIO may not invest more than 10% of its total assets in "illiquid
securities" (securities for which market quotations are not readily available)
and repurchase agreements which have a maturity of longer than seven days. In
addition, no more than 15% of the EUROPEAN GROWTH PORTFOLIO's net assets will be
invested in such illiquid securities and foreign securities not traded on a
recognized domestic or foreign exchange. Generally, OTC options and the assets
used as "cover" for written OTC options are illiquid securities. However, these
Portfolios are permitted to treat the securities they use as cover for written
OTC options as liquid provided they follow a procedure whereby they will sell
OTC options only to qualified dealers who agree that the Portfolio may
repurchase such options at a maximum price to be calculated pursuant to a
predetermined formula set forth in the option agreement. The formula may vary
from agreement to agreement, but is generally based on a multiple of the premium
received by the Portfolio for writing the option plus the amount, if any, of the
option's intrinsic value. An OTC option is considered an illiquid asset only to
the extent that the maximum repurchase price under the formula exceeds the
intrinsic value of the option.
 
The HIGH YIELD PORTFOLIO may not acquire any common stocks, except (a) when
attached to or included in a unit with fixed-income securities; (b) when
acquired upon conversion of fixed-income securities; or (c) when acquired upon
exercise of warrants attached to fixed-income securities. However, the HIGH
YIELD PORTFOLIO may retain common stocks so acquired but not in excess of 10% of
its total assets. While the EQUITY PORTFOLIO may not invest in securities of
foreign issuers, it may invest in (a) securities of Canadian issuers registered
under the Securities Exchange Act of 1934 and (b) American Depository Receipts.
 
All percentage limitations apply immediately after a purchase or initial
investment, and any subsequent change in any applicable percentage resulting
from market fluctuations or other changes in the amount of total assets does not
require elimination of any security from the Portfolio.
 
DETERMINATION OF NET ASSET VALUE
- ----------------------------------------------------------
 
The net asset value per share is calculated separately for each Portfolio. In
general, the net asset value per share is computed by taking the value of all
the assets of the Portfolio, subtracting all liabilities, dividing by the number
of shares outstanding and
 
                                       42
<PAGE>
adjusting the result to the nearest cent. The Fund will compute the net asset
value per share of each Portfolio once daily at 4:00 p.m., New York time (or, on
days when the New York Stock Exchange closes prior to 4:00 p.m., at such earlier
time), on days the New York Stock Exchange is open for trading. The net asset
value per share will not be determined on Good Friday and on such other Federal
and non-Federal holidays as are observed by the New York Stock Exchange.
 
The MONEY MARKET PORTFOLIO utilizes the amortized cost method in valuing its
portfolio securities, which method involves valuing a security at its cost
adjusted by a constant amortization to maturity of any discount or premium,
regardless of the impact of fluctuating interest rates on the market value of
the instrument. The purpose of this method of calculation is to facilitate the
maintenance of a constant net asset value per share of $1.00. However, there can
be no assurance that the $1.00 net asset value will be maintained.
 
In the calculation of the net asset value of the Portfolios other than the MONEY
MARKET PORTFOLIO: (1) an equity portfolio security listed or traded on the New
York or American Stock Exchange or other domestic or foreign stock exchange is
valued at its latest sale price on that exchange prior to the time when assets
are valued (if there were no sales that day, the security is valued at the
latest bid price) (in cases where securities are traded on more than one
exchange, the securities are valued on the exchange designated as the primary
market pursuant to procedures adopted by the Trustees); and (2) all other
portfolio securities for which over-the-counter market quotations are readily
available are valued at the latest bid price prior to the time of valuation.
When market quotations are not readily available, including circumstances under
which it is determined by the Investment Manager (or, in the case of the
EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH PORTFOLIO, by the Sub-Adviser)
that sale or bid prices are not reflective of a security's market value,
portfolio securities are valued at their fair value as determined in good faith
under procedures established by and under the general supervision of the Fund's
Board of Trustees (valuation of securities for which market quotations are not
readily available may also be based upon current market prices of securities
which are comparable in coupon, rating and maturity or an appropriate matrix
utilizing similar factors). For valuation purposes, quotations of foreign
portfolio securities, other assets and liabilities and forward contracts stated
in foreign currency are translated into U.S. dollar equivalents at the
prevailing market rates prior to the close of the New York Stock Exchange.
Dividends receivable are accrued as of the ex-dividend date except for certain
dividends from foreign securities which are accrued as soon as the Fund is
informed of such dividends after the ex-dividend date.
 
Short-term debt securities with remaining maturities of sixty days or less at
the time of purchase are valued at amortized cost, unless the Trustees determine
such does not reflect the securities' market value, in which case these
securities will be valued at their fair value as determined by the Trustees.
 
Generally, trading in foreign securities, as well as corporate bonds, U.S.
Government securities and money market instruments, is substantially completed
each day at various times prior to the close of the New York Stock Exchange. The
values of such securities used in computing the net asset value of a Portfolio's
shares are determined as of such times. Foreign currency exchange rates are also
generally determined prior to the close of the New York Stock Exchange.
Occasionally, events which may affect the values of such securities and such
exchange rates may occur between the times at which they are determined and the
close of the New York Stock Exchange and will therefore not be reflected in the
computation of a Portfolio's net asset value. If events that may affect the
value of such securities occur during such period, then these securities may be
valued at their fair value as determined in good faith under procedures
established by and under the supervision of the Trustees.
 
Certain of the portfolio securities of each Portfolio other than the MONEY
MARKET PORTFOLIO may be valued by an outside pricing service approved by the
Fund's Trustees. The pricing service may utilize a matrix system incorporating
security quality, maturity and coupon as the evaluation model parameters, and/or
research evaluations by its staff, including review of broker-dealer market
price quotations, in determining what it believes is the fair valuation of the
portfolio securities valued by such pricing service.
 
PURCHASE OF FUND SHARES
- ----------------------------------------------------------
 
Investments in the Fund may be made only by (1) Northbrook Life Insurance
Company ("Northbrook") for allocation to certain separate accounts established
and maintained by Northbrook for the purpose of funding variable annuity
contracts and variable life insurance contracts it issues, by (2) Allstate Life
Insurance Company of New York ("Allstate New York") for allocation to certain
separate accounts established and maintained by Allstate New York for the
purpose of funding variable annuity contracts it issues, by (3) Glenbrook Life
and Annuity Company ("Glenbrook") for allocation to certain separate accounts
established and maintained by Glenbrook for the purpose of funding variable
annuity contracts and variable life insurance contracts it issues, and by (4)
Paragon Life Insurance Company ("Paragon") for allocation to a separate account
established and maintained by Paragon for the purpose of funding variable life
insurance contracts it issues, in connection with an employer-
 
                                       43
<PAGE>
sponsored insurance program offered only to certain employees of MSDW, the
parent company of the Fund's Investment Manager. The separate accounts are
sometimes referred to individually as an "Account" and collectively as the
"Accounts." Persons desiring to purchase annuity or life insurance contracts
funded by any Portfolio of the Fund should read this Prospectus in conjunction
with the Prospectus of the flexible premium deferred annuity contracts issued by
Northbrook, Allstate New York or Glenbrook (the "Variable Annuity Contracts") or
in conjunction with the Prospectus of the flexible premium variable life
insurance contracts issued by Northbrook, Glenbrook or Paragon (the "Variable
Life Contracts").
 
In the future, shares of the Portfolios of the Fund may be allocated to certain
other separate accounts or sold to affiliated and/or non-affiliated entities of
Northbrook, Allstate New York, Glenbrook and Paragon (the "Companies") in
connection with variable annuity contracts or variable life insurance contracts.
It is conceivable that in the future it may become disadvantageous for both
variable life and variable annuity contract separate accounts to invest in the
same underlying fund. Although neither the Companies nor the Fund currently
foresee any such disadvantage, the Fund's Board of Trustees intends to monitor
events in order to identify any material irreconcilable conflict between the
interests of variable annuity contract owners and variable life insurance
contract owners and to determine what action, if any, should be taken in
response thereto.
 
Shares of each Portfolio of the Fund are offered to the Companies for allocation
to the Accounts without sales charge at the respective net asset values of the
Portfolios next determined after receipt by the Fund of the purchase payment in
the manner set forth above under "Determination of Net Asset Value." In the
interest of economy and convenience, certificates representing the Fund's shares
will not be physically issued. Dean Witter Distributors Inc. (the "Distributor")
acts without remuneration from the Fund as the exclusive Distributor of the
Fund's shares. (The Distributor is a wholly-owned subsidiary of MSDW and an
affiliate of Dean Witter Reynolds Inc., which is the principal underwriter of
certain of the Variable Annuity Contracts and the Variable Life Contracts.) The
principal executive office of the Distributor is located at Two World Trade
Center, New York, New York 10048.
 
REDEMPTION OF FUND SHARES
- ----------------------------------------------------------
 
Shares of any Portfolio of the Fund can be redeemed by the Companies at any time
for cash, without sales charge, at the net asset value next determined after
receipt of the redemption request. (For information regarding charges which may
be imposed upon the Contracts by the applicable Account, see the accompanying
Prospectus for either the Variable Annuity Contracts or the Variable Life
Contracts.)
 
The Fund reserves the right to suspend the right of redemption or to postpone
the date of payment upon redemption of the
shares of any Portfolio for any period during which the New York Stock Exchange
is closed (other than weekend and holiday closings) or trading on that Exchange
is restricted, or during which an emergency exists (as determined by the
Securities and Exchange Commission) as a result of which disposal of the
portfolio securities owned by the Portfolio is not reasonably practicable or it
is not reasonably practicable for the Portfolio to determine the value of its
net assets, or for such other period as the Securities and Exchange Commission
may by order permit for the protection of shareholders.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- ----------------------------------------------------------
 
DIVIDENDS AND DISTRIBUTIONS. The Fund intends to distribute substantially all of
the net investment income and net realized capital gains, if any, of each
Portfolio. Dividends from net investment income and any distributions of
realized capital gains will be paid in additional shares of the Portfolio paying
the dividend or making the distribution and credited to the shareholder's
account.
 
MONEY MARKET PORTFOLIO. Dividends from net income on the MONEY MARKET PORTFOLIO
will be declared, payable on each day the New York Stock Exchange is open for
business to shareholders of record as of the close of business the preceding
business day. Net income, for dividend purposes, includes accrued interest and
accretion of acquisition, original issue and market discount, less the
amortization of market premium and the estimated expenses of the MONEY MARKET
PORTFOLIO. The amount of dividend may fluctuate from day to day and may be
omitted on some days if realized losses on portfolio securities exceed the MONEY
MARKET PORTFOLIO's net investment income. Dividends are automatically reinvested
daily in additional shares of the MONEY MARKET PORTFOLIO at the net asset value
per share at the close of business that day. Any net realized capital gains will
be declared and paid
 
                                       44
<PAGE>
at least once per calendar year; net short-term gains may be paid more
frequently, with the distribution of dividends from net investment income.
 
QUALITY INCOME PLUS PORTFOLIO AND HIGH YIELD PORTFOLIO. Dividends from net
investment income on the QUALITY INCOME PLUS PORTFOLIO and the HIGH YIELD
PORTFOLIO will be declared and paid monthly, and any net realized capital gains
will be declared and paid at least once per calendar year.
 
UTILITIES PORTFOLIO, INCOME BUILDER PORTFOLIO, DIVIDEND GROWTH PORTFOLIO, GLOBAL
DIVIDEND GROWTH PORTFOLIO, EQUITY PORTFOLIO AND STRATEGIST PORTFOLIO. Dividends
from net investment income, if any, on the UTILITIES PORTFOLIO, the INCOME
BUILDER PORTFOLIO, the DIVIDEND GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH
PORTFOLIO, the EQUITY PORTFOLIO and the STRATEGIST PORTFOLIO will be declared
and paid quarterly, and any net realized capital gains will be declared and paid
at least once per calendar year.
 
CAPITAL GROWTH PORTFOLIO, EUROPEAN GROWTH PORTFOLIO, PACIFIC GROWTH PORTFOLIO,
CAPITAL APPRECIATION PORTFOLIO, S&P 500 INDEX PORTFOLIO AND COMPETITIVE EDGE
"BEST IDEAS" PORTFOLIO. Dividends from net investment income and net realized
capital gains, if any, on the CAPITAL GROWTH PORTFOLIO, the EUROPEAN GROWTH
PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the
S&P 500 INDEX PORTFOLIO and the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO will be
declared and paid at least once per calendar year.
 
TAXES. Because the Fund intends to distribute substantially all of the net
investment income and capital gains of each Portfolio and otherwise continue to
qualify each Portfolio as a regulated investment company under Subchapter M of
the Internal Revenue Code (the "Code"), it is not expected that any Portfolio of
the Fund will be required to pay any Federal income tax on such income and
capital gains.
 
Gains or losses on a Portfolio's transactions in certain listed options and on
futures and options on futures generally are treated as 60% long-term and 40%
short-term. When a Portfolio engages in options and futures transactions,
various tax regulations applicable to the Portfolio may have the effect of
causing the Portfolio to recognize a gain or loss for tax purposes before that
gain or loss is realized, or to defer recognition of a realized loss for tax
purposes. Recognition, for tax purposes, of an unrealized loss may result in a
lesser amount of the realized net short-term gains of the QUALITY INCOME PLUS
PORTFOLIO, the UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the GLOBAL
DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH
PORTFOLIO, the CAPITAL APPRECIATION PORTFOLIO, the S&P 500 INDEX PORTFOLIO or
the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO or the STRATEGIST PORTFOLIO being
available for distribution. These Portfolios intend to make certain elections
which may minimize the impact of these rules but which could also result in a
higher portion of the Portfolio's gains being treated as short-term capital
gains.
 
With respect to investments by a Portfolio in zero coupon bonds and investment
by the HIGH YIELD PORTFOLIO in payment-in-kind bonds, the Portfolios accrue
income prior to any actual cash payments by their issuers. In order to continue
to comply with Subchapter M of the Code and remain able to forego payment of
Federal income tax on their income and capital gains, each Portfolio must
distribute all of its net investment income, including income accrued from zero
coupon and payment-in-kind bonds. As such, a Portfolio may be required to
dispose of some of its portfolio securities under disadvantageous circumstances
to generate the cash required for distribution.
 
Dividends, interest and capital gains received by a Portfolio on investments in
foreign issuers or which are denominated in foreign currency may give rise to
withholding and other taxes imposed by foreign countries, which may or may not
be refunded to the Portfolio.
 
Since the Companies are the only shareholders of the Fund, no discussion is
stated herein as to the Federal income tax consequences at the shareholder
level. For information concerning the Federal income tax consequences to holders
of variable annuity or variable life insurance contracts, see the accompanying
Prospectus for either the Variable Annuity Contracts or the Variable Life
Contracts.
 
PERFORMANCE INFORMATION
- ----------------------------------------------------------
 
From time to time the Fund advertises the "yield" and "effective yield" of the
MONEY MARKET PORTFOLIO. Both yield figures are based on historical earnings and
are not intended to indicate future performance. The "yield" of the MONEY MARKET
PORTFOLIO refers to the income generated by an investment in the Portfolio over
a given period (which period will be stated in the advertisement). This income
is then annualized. The "effective yield" for a seven-day period is calculated
similarly but, when annualized, the income earned by an investment in the MONEY
MARKET PORTFOLIO is assumed to be reinvested each week within a 365-day period.
The "effective yield" will be slightly higher than the "yield" because of the
compounding effect of this assumed reinvestment. The MONEY MARKET PORTFOLIO's
"yield" and "effective yield" do not reflect the deduction of any charges which
may be imposed on the Contracts by the applicable Account and are therefore not
equivalent to total return under a Contract (for a description of such charges,
see the Prospectus for the Contracts).
 
From time to time the Fund advertises the "yield" of each of the QUALITY INCOME
PLUS PORTFOLIO, the HIGH YIELD PORTFOLIO and the UTILITIES PORTFOLIO. The yield
of a Portfolio is based on historical
 
                                       45
<PAGE>
earnings and is not intended to indicate future performance. The yield of a
Portfolio is computed by dividing the Portfolio's net investment income over a
30-day period by an average value (using the average number of shares entitled
to receive dividends and the net asset value per share at the end of the
period), all in accordance with applicable regulatory requirements. Such amount
is compounded for six months and then annualized for a twelve-month period to
derive the Portfolio's yield. The "yield" of a Portfolio does not reflect the
deduction of any charges which may be imposed on the Contracts by the applicable
Account and is therefore not equivalent to total return under a Contract (for a
description of such charges, see the Prospectus for the Contracts).
 
From time to time the Fund may quote the "total return" of each Portfolio in
advertisements and sales literature. The total return of a Portfolio is based on
historical earnings and is not intended to indicate future performance. The
"average annual total return" of a Portfolio refers to a figure reflecting the
average annualized percentage increase (or decrease) in the value of an initial
investment in the Portfolio of $1,000 over periods of one, five and ten years,
as well as over the life of the Portfolio, if shorter than any of these periods.
Average annual total return reflects all income earned by the Portfolio, any
appreciation or depreciation of the Portfolio's assets and all expenses incurred
by the Portfolio for the stated periods. It also assumes reinvestment of all
dividends and distributions paid by the Portfolio. However, average annual total
return does not reflect the deduction of any charges which may be imposed on the
Contracts by the applicable Account which, if reflected, would reduce the
performance quoted.
 
In addition to the foregoing, the Fund may advertise the total return of the
Portfolios over different periods of time by means of aggregate, average,
year-by-year or other types of total return figures. Such calculations similarly
do not reflect the deduction of any charges which may be imposed on the
Contracts by the applicable Account. The Fund may also advertise the growth of
hypothetical investments of $10,000, $50,000 and $100,000 in shares of a
Portfolio. The Fund from time to time may also advertise the performance of the
Portfolios relative to certain performance rankings and indexes compiled by
independent organizations, such as Lipper Analytical Services, Inc.
 
ADDITIONAL INFORMATION
- ----------------------------------------------------------
 
The shares of beneficial interest of the Fund, with $0.01 par value, are divided
into fifteen separate Portfolios, and the shares of each Portfolio are equal as
to earnings, assets and voting privileges with all other shares of that
Portfolio. There are no conversion, pre-emptive or other subscription rights.
Upon liquidation of the Fund or any Portfolio, shareholders of a Portfolio are
entitled to share pro rata in the net assets of that Portfolio available for
distribution to shareholders after all debts and expenses have been paid. The
shares do not have cumulative voting rights.
 
The assets received by the Fund on the sale of shares of each Portfolio and all
income, earnings, profits and proceeds thereof, subject only to the rights of
creditors, are allocated to each Portfolio, and constitute the assets of such
Portfolio. The assets of each Portfolio are required to be segregated on the
Fund's books of account.
 
Additional Portfolios (the proceeds of which would be invested in separate,
independently managed portfolios with distinct investment objectives, policies
and restrictions) may be offered in the future, but such additional offerings
would not affect the interests of the current shareholders in the existing
Portfolios.
 
On any matters affecting only one Portfolio, only the shareholders of that
Portfolio are entitled to vote. On matters relating to all the Portfolios but
affecting the Portfolios differently, separate votes by Portfolio are required.
Approval of an Investment Management Agreement and a change in fundamental
policies would be regarded as matters requiring separate voting by each
Portfolio. To the extent required by law, Northbrook Life Insurance Company,
Allstate Life Insurance Company of New York, Glenbrook Life and Annuity Company
and Paragon Life Insurance Company, which are the only shareholders of the Fund,
will vote the shares of the Fund held in each Account in accordance with
instructions from Contract Owners, as more fully described under the caption
"Voting Rights" in the accompanying Prospectus for either the Variable Annuity
Contracts or the Variable Life Contracts. The Trustees of the Fund have been
elected by Northbrook Life Insurance Company, Allstate Life Insurance Company of
New York and Paragon Life Insurance Company, pursuant to the instructions of
Contract Owners.
 
The Fund is not required to hold Annual Meetings of Shareholders and in ordinary
circumstances the Fund does not intend to hold such meetings. The Trustees may
call Special Meetings of Shareholders for action by shareholder vote as may be
required by the Act or the Declaration of Trust.
 
Under Massachusetts law, shareholders of a business trust may, under certain
circumstances, be held personally liable as partners for the obligations of the
Fund. However, the Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Fund, requires that Fund
obligations
 
                                       46
<PAGE>
include such disclaimer, and provides for indemnification and reimbursement of
expenses out of the Fund's property for any shareholder held personally liable
for the obligations of the Fund. Thus, the risk of a shareholder incurring
financial loss on account of shareholder liability is limited to circumstances
in which the Fund itself would be unable to meet its obligations. Given the
above limitations on shareholder personal liability, and the nature of the
Fund's assets and operations, in the opinion of Massachusetts counsel to the
Fund, the risk to shareholders of personal liability is remote.
 
TRANSFER AGENT AND DIVIDEND DISBURSING AGENT. Morgan Stanley Dean Witter Trust
FSB, an affiliate of InterCapital and the Distributor, whose address is
Harborside Financial Center, Plaza Two, Jersey City, NJ 07311, is the Transfer
Agent of the Fund's shares and Dividend Disbursing Agent for payments of
dividends and distributions on Fund shares.
 
CODE OF ETHICS. Directors, officers and employees of InterCapital, Dean Witter
Services Company Inc. and the Distributor are subject to a strict Code of Ethics
adopted by those companies. The Code of Ethics is intended to ensure that the
interests of shareholders and other clients are placed ahead of any personal
interest, that no undue personal benefit is obtained from a person's employment
activities and that actual and potential conflicts of interest are avoided. To
achieve these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an advance clearance process to monitor that no
investment company managed or advised by InterCapital ("Dean Witter Fund") is
engaged at the same time in a purchase or sale of the same security. The Code of
Ethics bans the purchase of securities in an initial public offering, and also
prohibits engaging in futures and options transactions and profiting on
short-term trading (that is, a purchase within sixty days of a sale or a sale
within sixty days of a purchase) of a security. In addition, investment
personnel may not purchase or sell a security for their personal account within
thirty days before or after any transaction in any Dean Witter Fund managed by
them. Any violations of the Code of Ethics are subject to sanctions, including
reprimand, demotion or suspension or termination of employment. The Code of
Ethics comports with regulatory requirements and the recommendations in the 1994
report by the Investment Company Institute Advisory Group on Personal Investing.
 
The Sub-Adviser of the EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH
PORTFOLIO also has a Code of Ethics which complies with regulatory requirements
and, insofar as it relates to persons associated with the Fund, the 1994 report
by the Investment Company Institute Advisory Group on Personal Investing.
 
YEAR 2000.  The investment management services provided to the Fund by the
Investment Manager and the Sub-Adviser and the services provided to shareholders
by the Distributor and the Transfer Agent depend on the smooth functioning of
their computer systems. Many computer software systems in use today cannot
recognize the year 2000, but revert to 1900 or some other date, due to the
manner in which dates were encoded and calculated. That failure could have a
negative impact on the handling of securities trades, pricing and account
services. The Investment Manager, the Sub-Adviser, the Distributor and the
Transfer Agent have been actively working on necessary changes to their own
computer systems to prepare for the year 2000 and expect that their systems will
be adapted before that date, but there can be no assurance that they will be
successful, or that interaction with other non-complying computer systems will
not impair their services at that time. In addition, it is possible that the
markets for securities in which the Fund invests may be detrimentally affected
by computer failures throughout the financial services industry beginning
January 1, 2000. Improperly functioning trading systems may result in settlement
problems and liquidity issues. In addition, corporate and governmental data
processing errors may result in production problems for individual companies and
overall economic uncertainties. Earnings of individual issuers will be affected
by remediation costs, which may be substantial and may be reported
inconsistently in U.S. and foreign financial statements. Accordingly, the Fund's
investments may be adversely affected.
 
SHAREHOLDER INQUIRIES. All inquiries regarding the Fund should be directed to
the Fund at the telephone numbers or address set forth on the front cover of
this Prospectus.
 
INITIAL SHAREHOLDER--S&P 500 INDEX PORTFOLIO.  Northbrook Life Insurance Company
has undertaken to purchase 200,000 shares of the S&P 500 INDEX PORTFOLIO, for a
purchase price of $2 million, prior to the commencement of that Portfolio's
operations. Northbrook may redeem such shares at any time after the net assets
of the S&P 500 INDEX PORTFOLIO have attained a sufficient level so that such
redemption will not cause disruption of the operations of the Portfolio.

MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
 
                         FIXED-INCOME SECURITY RATINGS
 
<TABLE>
<S>        <C>
Aaa        Fixed-income securities 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.
 
Aa         Fixed-income securities 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 fixed-income
           securities. They are rated lower than the best fixed-income securities 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.
 
A          Fixed-income securities 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
           sometime in the future.
 
Baa        Fixed-income securities 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 fixed-income securities lack
           outstanding investment characteristics and in fact have speculative characteristics as well.
 
           Fixed-income securities rated Aaa, Aa, A and Baa are considered investment grade.
 
Ba         Fixed-income securities which are rated Ba are judged to have speculative elements; their future
           cannot be considered as well assured. Often the protection of interest and principal payments may
           be very moderate, and therefore not well safeguarded during both good and bad times in the future.
           Uncertainty of position characterizes bonds in this class.
 
B          Fixed-income securities which are rated B generally lack characteristics of the 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.
 
Caa        Fixed-income securities which are rated Caa are of poor standing. Such issues may be in default or
           there may be present elements of danger with respect to principal or interest.
 
Ca         Fixed-income securities which are rated Ca present obligations which are speculative in a high
           degree. Such issues are often in default or have other marked shortcomings.
 
C          Fixed-income securities which are rated C are the lowest rated class of fixed-income securities,
           and issues so rated can be regarded as having extremely poor prospects of ever attaining any real
           investment standing.
</TABLE>
 
    RATING REFINEMENTS:  Moody's may apply numerical modifiers, 1, 2, and 3 in
each generic rating classification from Aa through B in its municipal
fixed-income security rating system. The modifier 1 indicates that the security
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking; and a modifier 3 indicates that the issue ranks in the
lower end of its generic rating category.

                            COMMERCIAL PAPER RATINGS
 
Moody's Commercial Paper ratings are opinions of the ability to repay punctually
promissory obligations not having an original maturity in excess of nine months.
The ratings apply to Municipal Commercial Paper as well as taxable Commercial
Paper. Moody's employs the following three designations, all judged to be
investment grade, to indicate the relative repayment capacity of rated issuers:
Prime-1, Prime-2, Prime-3.
 
Issuers rated Prime-1 have a superior capacity for repayment of short-term
promissory obligations. Issuers rated Prime-2 have a strong capacity for
repayment of short-term promissory obligations; and Issuers rated Prime-3 have
an acceptable capacity for repayment of short-term promissory obligations.
Issuers rated Not Prime do not fall within any of the Prime rating categories.
 
STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                         FIXED-INCOME SECURITY RATINGS
 
A Standard & Poor's fixed-income security rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers, or
lessees.
 
The ratings are based on current information furnished by the issuer or obtained
by Standard & Poor's from other sources it considers reliable. The ratings are
based, in varying degrees, on the following considerations: (1) likelihood of
default-capacity and willingness of the obligor as to the timely payment of
interest and repayment of principal in accordance with the terms of the
obligation; (2) nature of and provisions of the obligation; and (3) protection
afforded by, and relative position of, the obligation in the event of
bankruptcy, reorganization or other arrangement under the laws of bankruptcy and
other laws affecting creditors' rights.
 
Standard & Poor's does not perform an audit in connection with any rating and
may, on occasion, rely on unaudited financial information. The ratings may be
changed, suspended or withdrawn as a result of changes in, or unavailability of,
such information, or for other reasons.
 
<TABLE>
<S>        <C>
AAA        Fixed-income securities rated "AAA" have the highest rating assigned by Standard & Poor's.
           Capacity to pay interest and repay principal is extremely strong.
 
AA         Fixed-income securities rated "AA" have a very strong capacity to pay interest and repay
           principal and differs from the highest-rate issues only in small degree.
 
A          Fixed-income securities rated "A" have a strong capacity to pay interest and repay principal
           although they are somewhat more susceptible to the adverse effects of changes in circumstances
           and economic conditions than fixed-income securities in higher-rated categories.
 
BBB        Fixed-income securities rated "BBB" are regarded as having an adequate capacity to pay interest
           and repay principal. Whereas it normally exhibits adequate protection parameters, adverse
           economic conditions or changing circumstances are more likely to lead to a weakened capacity to
           pay interest and repay principal for fixed-income securities in this category than for fixed-
           income securities in higher-rated categories.
 
           Fixed-income securities rated AAA, AA, A and BBB are considered investment grade.
 
BB         Fixed-income securities rated "BB" have less near-term vulnerability to default than other
           speculative grade fixed-income securities. However, it faces major ongoing uncertainties or
           exposures to adverse business, financial or economic conditions which could lead to inadequate
           capacity or willingness to pay interest and repay principal.
 
B          Fixed-income securities rated "B" have a greater vulnerability to default but presently have the
           capacity to meet interest payments and principal repayments. Adverse business, financial or
           economic conditions would likely impair capacity or willingness to pay interest and repay
           principal.
 
CCC        Fixed-income securities rated "CCC" have a current identifiable vulnerability to default, and are
           dependent upon favorable business, financial and economic conditions to meet timely payments of
           interest and repayments of principal. In the event of adverse business, financial or economic
           conditions, they are not likely to have the capacity to pay interest and repay principal.
 
CC         The rating "CC" is typically applied to fixed-income securities subordinated to senior debt which
           is assigned an actual or implied "CCC" rating.
 
C          The rating "C" is typically applied to fixed-income securities subordinated to senior debt which
           is assigned an actual or implied "CCC-" rating.

<PAGE>
<TABLE>
<S>        <C>
CI         The rating "CI" is reserved for fixed-income securities on which no interest is being paid.
 
NR         Indicates that no rating has been requested, that there is insufficient information on which to
           base a rating or that Standard & Poor's does not rate a particular type of obligation as a matter
           of policy.
 
           Fixed-income securities rated "BB," "B," "CCC," "CC" and "C" are regarded as having predominantly
           speculative characteristics with respect to capacity to pay interest and repay principal. "BB"
           indicates the least degree of speculation and "C" the highest degree of speculation. While such
           fixed-income securities will likely have some quality and protective characteristics, these are
           outweighed by large uncertainties or major risk exposures to adverse conditions.
 
           Plus (+) or minus (-): The rating from "AA" to "CCC" may be modified by the addition of a plus or
           minus sign to show relative standing within the major ratings categories.
</TABLE>
 
                            COMMERCIAL PAPER RATINGS
 
Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The commercial paper rating is not a recommendation to purchase or
sell a security. The ratings are based upon current information furnished by the
issuer or obtained by Standard & Poor's from other sources it considers
reliable. The ratings may be changed, suspended, or withdrawn as a result of
changes in or unavailability of such information. Ratings are graded into group
categories, ranging from "A" for the highest quality obligations to "D" for the
lowest. Ratings are applicable to both taxable and tax-exempt commercial paper.
The categories are as follows:
 
Issues assigned A ratings are regarded as having the greatest capacity for
timely payment. Issues in this category are further refined with the designation
1, 2, and 3 to indicate the relative degree of safety.
 
<TABLE>
<S>        <C>
A-1        indicates that the degree of safety regarding timely payment is very strong.
 
A-2        indicates capacity for timely payment on issues with this designation is strong. However, the
           relative degree of safety is not as overwhelming as for issues designated "A-1."
 
A-3        indicates a satisfactory capacity for timely payment. Obligations carrying this designation are,
           however, somewhat more vulnerable to the adverse effects of changes in circumstances than
           obligations carrying the higher designations.

FITCH INVESTORS SERVICE, INC. ("FITCH")
 
                                  BOND RATINGS
 
The Fitch Bond Ratings provides a guide to investors in determining the
investment risk associated with a particular security. The rating represents its
assessment of the issuer's ability to meet the obligations of a specific debt
issue or class of debt in a timely manner. Fitch bond ratings are not
recommendations to buy, sell or hold securities since they incorporate no
information on market price or yield relative to other debt instruments.
 
The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the record of the issuer and of
any guarantor, as well as the political and economic environment that might
affect the future financial strength and credit quality of the issuer.
 
Bonds which have the same rating are of similar but not necessarily identical
investment quality since the limited number of rating categories cannot fully
reflect small differences in the degree of risk. Moreover, the character of the
risk factor varies from industry to industry and between corporate, health care
and municipal               .
 
In assessing credit risk, Fitch Investors Service relies on current information
furnished by the issuer and/or guarantor and other sources which it considers
reliable. Fitch does not perform an audit of the financial statements used in
assigning a rating.
 
Ratings may be changed, withdrawn or suspended at any time to reflect changes in
the financial condition of the issuer, the status of the issue relative to other
debt of the issuer, or any other circumstances that Fitch considers to have a
material effect on the credit of the obligor.
 
<TABLE>
<S>        <C>
AAA        rated bonds are considered to be investment grade and of the highest credit quality. The obligor
           has an exceptionally strong ability to pay interest and repay principal, which is unlikely to be
           affected by reasonably foreseeable events.
</TABLE>

<PAGE>
<TABLE>
<S>        <C>
AA         rated bonds are considered to be investment grade and of very high credit quality. The obligor's
           ability to pay interest and repay principal, while very strong, is somewhat less than for AAA
           rated securities or more subject to possible change over the term of the issue.
 
A          rated bonds are considered to be investment grade and of high credit quality. The obligor's
           ability to pay interest and repay principal is considered to be strong, but may be more
           vulnerable to adverse changes in economic conditions and circumstances than bonds with higher
           ratings.
 
BBB        rated bonds are considered to be investment grade and of satisfactory credit quality. The
           obligor's ability to pay interest and repay principal is considered to be adequate. Adverse
           changes in economic conditions and circumstances, however, are more likely to weaken this ability
           than bonds with higher ratings.
 
BB         rated bonds are considered speculative and of low investment grade. The obligor's ability to pay
           interest and repay principal is not strong and is considered likely to be affected over time by
           adverse economic changes.
 
B          rated bonds are considered highly speculative. Bonds in this class are lightly protected as to
           the obligor's ability to pay interest over the life of the issue and repay principal when due.
 
CCC        rated bonds may have certain identifiable characteristics which, if not remedied, could lead to
           the possibility of default in either principal or interest payments.
 
CC         rated bonds are minimally protected. Default in payment of interest and/or principal seems
           probable.
 
C          rated bonds are in imminent default in payment of interest and/or principal.
</TABLE>
 
                               SHORT-TERM RATINGS
 
Fitch's short-term ratings apply to debt obligations that are payable on demand
or have original maturities of generally up to three years, including commercial
paper, certificates of deposit, medium-term notes, and municipal and investment
notes. Although the credit analysis is similar to Fitch's bond rating analysis,
the short-term rating places greater emphasis on the existence of liquidity
necessary to meet the issuer's obligations in a timely manner. Fitch's
short-term ratings are as follows:
 
<TABLE>
<S>        <C>
Fitch-1+   (Exceptionally Strong Credit Quality) Issues assigned this rating are regarded as having the
           strongest degree of assurance for timely payment.
 
Fitch-1    (Very Strong Credit Quality) Issues assigned this rating reflect an assurance of timely
           payment only slightly less in degree than issues rated Fitch-1+.
 
Fitch-2    (Good Credit Quality) Issues assigned this rating have a satisfactory degree of assurance for
           timely payment but the margin of safety is not as great as the two higher categories.
 
Fitch-3    (Fair Credit Quality) Issues assigned this rating have characteristics suggesting that the
           degree of assurance for timely payment is adequate, however, near-term adverse change is
           likely to cause these securities to be rated below investment grade.
 
Fitch-S    (Weak Credit Quality) Issues assigned this rating have characteristics suggesting a minimal
           degree of assurance for timely payment and are vulnerable to near term adverse changes in
           financial and economic conditions.
 
D          (Default) Issues assigned this rating are in actual or imminent payment default.
 
LOC        This symbol LOC indicates that the rating is based on a letter of credit issued by a
           commercial bank.

DUFF & PHELPS, INC.
 
                               LONG-TERM RATINGS
 
These ratings represent a summary opinion of the issuer's long-term fundamental
quality. Rating determination is based on qualitative and quantitative factors
which may vary according to the basic economic and financial characteristics of
each industry and each issuer. Important considerations are vulnerability to
economic cycles as well as risks related to such factors as competition,
government action, regulation, technological obsolescence, demand shifts, cost
structure, and management depth and expertise. The projected viability of the
obligor at the trough of the cycle is a critical determination.
 
                                       51
<PAGE>
Each rating also takes into account the legal form of the security, (E.G., first
mortgage bonds, subordinated debt, preferred stock, etc.). The extent of rating
dispersion among the various classes of securities is determined by several
factors including relative weightings of the different security classes in the
capital structure, the overall credit strength of the issuer, and the nature of
covenant protection. Review of indenture restrictions is important to the
analysis of a company's operating and financial constraints.
 
The Credit Rating Committee formally reviews all ratings once per quarter (more
frequently, if necessary).

                               SHORT-TERM RATINGS
 
Duff & Phelps' short-term ratings are consistent with the rating criteria
utilized by money market participants. The ratings apply to all obligations with
maturities of under one year, including commercial paper, the uninsured portion
of certificates of deposit, unsecured bank loans, master notes, bankers
acceptances, irrevocable letters of credit, and current maturities of long-term
debt. Asset-backed commercial paper is also rated according to this scale.
 
Emphasis is placed on liquidity which is defined as not only cash from
operations, but also access to alternative sources of funds, including trade
credit, bank lines, and the capital markets. An important consideration is the
level of an obligor's reliance on short-term funds on an ongoing basis.

A. Category 1:    High Grade
 
Duff 1+           Highest certainty of timely payment. Short-term liquidity,
                  including internal operating factors and/or access to
                  alternative sources of funds, is outstanding, and safety is
                  just below risk-free U.S. Treasury short-term obligations.
 
Duff 1            Very high certainty of timely payment. Liquidity factors are
                  excellent and supported by good fundamental protection
