THE PORTFOLIOS

THE MONEY MARKET PORTFOLIO

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The Money Market Portfolio seeks high current income,
                    preservation of capital and liquidity.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio invests in high quality, short-term debt
                    obligations. In selecting investments, the "Investment
                    Manager," Morgan Stanley Dean Witter Advisors Inc., seeks to
                    maintain the Portfolio's share price at $1.00. A mutual
                    fund's share price remaining stable at $1.00 means that the
                    fund would preserve the principal value of the shareholders'
                    investments.

                    The Portfolio's investments are limited, as a matter of
                    fundamental investment policy, which may not be changed
                    without shareholder approval, to the following types of
                    money market instruments:

                                                   rated at least AA by S&P or Aa by Moody's;

                                                   having total assets of $1 billion or more, and investments
                                                   secured by these obligations;
 -   Eurodollar certificates of deposit --         issued by foreign branches of domestic banks having assets

 -   repurchase agreements --                      which may be viewed as a type of secured lending by the
                                                   Portfolio.

<PAGE>
                    The Portfolio may purchase debt obligations that have fixed,
                    variable or floating rates of interest. The interest rates
                    payable on variable rate or floating rate obligations may
                    fluctuate based upon changes in market rates.

                    The Portfolio attempts to balance its objectives of high
                    income, capital preservation and liquidity by investing in
                    securities of varying maturities and risks. The Portfolio
                    does not, however, invest in securities that mature in more
                    than one year from the date of purchase.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objectives.

                    Principal risks of investing in the Portfolio are associated
                    with its debt obligation investments. All debt obligations,
                    such as bonds, are subject to two types of risk: credit risk
                    and interest rate risk. Credit risk refers to the
                    possibility that the issuer of a security will be unable to
                    make interest payments and/or repay the principal on its
                    debt. Interest rate risk refers to fluctuations in the value
                    of a debt security resulting from changes in the general
                    level of interest rates.

                    The Investment Manager actively manages the Portfolio's
                    assets to reduce the risk of losing any principal investment
                    as a result of credit or interest rate risks. The
                    Portfolio's assets are reviewed to maintain or improve
                    creditworthiness. In addition, federal regulations require
                    money market funds to invest only in debt obligations of
                    high quality and short maturities, and repurchase agreements
                    with respect to such obligations.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy.

                    An investment in the Portfolio is not a bank deposit and is
                    not guaranteed or insured by the FDIC or any other
                    government agency. Although the Portfolio seeks to preserve
                    the value of your investment at $1.00 per share, if it is
                    unable to do so, it is possible to lose money by investing
                    in the Portfolio.

                                                                               3

THE SHORT-TERM BOND PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Short-Term Bond Portfolio seeks to provide a high level
                    of current income consistent with the preservation of
                    capital.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in bonds issued or guaranteed as to principal and
                    interest by the U.S. Government, its agencies or
                    instrumentalities (including zero coupon securities), and
                    investment grade corporate and other types of bonds. In
                    selecting portfolio investments, the "Investment Manager,"
                    Morgan Stanley Dean Witter Advisors Inc., considers both
                    domestic and international economic developments, interest
                    rate trends and other factors and seeks to maintain an
                    overall weighted average maturity for the Portfolio of less
                    than three years.

                    MORTGAGE-BACKED SECURITIES. Certain of the U.S. Government
                    securities in which the Portfolio may invest are
                    mortgage-backed securities. One type of mortgage-backed
                    security, in which the Portfolio may invest, is a mortgage
                    pass-through security. These securities represent a
                    participation interest in a pool of residential mortgage
                    loans originated by U.S. Governmental or private lenders
                    such as banks. They differ from conventional debt
                    securities, which provide for periodic payment of interest
                    in fixed amounts and principal payments at maturity or on
                    specified call dates. Mortgage pass-through securities
                    provide for monthly payments that are a "pass-through" of
                    the monthly interest and principal payments made by the
                    individual borrowers on the pooled mortgage loans. Mortgage
                    pass-through securities may be collateralized by mortgages
                    with fixed rates of interest or adjustable rates.

                    In addition, the Portfolio may invest up to 25% of its
                    assets in investment grade fixed-income securities issued by
                    foreign governments or corporations. The
                    Portfolio's investments also may include "Rule 144A"
                    fixed-income securities, which are subject to resale
                    restrictions. Up to 5% of the Portfolio's assets may be
                    invested in fixed-income securities rated lower than
                    investment grade, or if unrated of comparable quality as
                    determined by the Investment Manager (commonly known as
                    "junk bonds").

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------

                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price and yield
                    will fluctuate with changes in the market value of its
                    portfolio securities. When you sell Portfolio shares, they
                    may be worth less than what you paid for them and,
                    accordingly, you can lose money investing in this Portfolio.


                    Principal risks of investing in the Portfolio are associated
                    with the Portfolio's investments in fixed-income securities.
                    These risks are credit risk and interest rate risk. Credit
                    risk is the possibility that the issuer of a security will
                    be unable to make

                                                                               5
<PAGE>
                    interest payments and/or repay the principal on its debt.
                    Interest rate risk refers to fluctuations in the value of a
                    fixed-income security resulting from changes in the general
                    level of interest rates.

                    There are also particular risks associated with the
                    Portfolio's investments in mortgage-backed securities. For
                    example mortgage-backed securities are subject to prepayment
                    risk and in some cases may be more volatile and less liquid
                    than other traditional types of debt securities.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.


                    The Portfolio commenced operations on May 3, 1999 and prior
                    to the date of this PROSPECTUS did not have a full calendar
                    year of performance to report.

THE QUALITY INCOME PLUS PORTFOLIO

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The Quality Income Plus Portfolio seeks as a primary
                    objective to provide a high level of current income by
                    investing primarily in U.S. government securities and other
                    fixed-income securities. As a secondary objective the
                    Portfolio seeks capital appreciation but only when
                    consistent with its primary objective.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in (i) U.S. Government securities issued or
                    guaranteed as to principal and interest by the U.S.
                    Government, its agencies or instrumentalities, (ii) debt
                    securities (including zero coupon securities), rated at the
                    time of purchase within the three highest bond rating
                    categories by Moody's or S&P or if not rated determined to
                    be of comparable quality by the "Investment Manager," Morgan
                    Stanley Dean Witter Advisors Inc., and (iii) Yankee
                    government bonds rated at the time of purchase within the
                    three highest rating categories of Moody's or S&P or if not
                    rated determined to be of comparable quality by the
                    Investment Manager. Yankee government bonds are U.S. dollar
                    denominated bonds issued by foreign government agencies or
                    instrumentalities (no more than 20% of the Portfolio's
                    assets may be invested in Yankee government bonds). The
                    Portfolio is not limited as to the maturities of the U.S.
                    Government and other debt securities in which it may invest.

                    In making investment decisions for the Portfolio, the
                    Investment Manager considers both domestic and international
                    economic developments, interest rate trends and other
                    factors. The Investment Manager evaluates technical
                    considerations such as the relative supply of and demand for
                    corporate notes and U.S. Treasury and agencies issues before
                    it decides upon an asset allocation. Similarly, the
                    assessment of the strength of individual companies that
                    issue corporate debt and the overall country risk of
                    sovereign debt obligations contribute to the decision-making
                    process.

                    MORTGAGE-BACKED SECURITIES. Certain of the U.S. Government
                    securities in which the Portfolio may invest are
                    mortgage-backed securities. One type of mortgage-backed
                    security, in which the Portfolio may invest, is a mortgage
                    pass-through security. These securities represent a
                    participation interest in a pool of residential mortgage
                    loans originated by U.S. Governmental or private lenders
                    such as banks. They differ from conventional debt
                    securities, which provide for periodic payment of interest
                    in fixed amounts and principal payments at maturity or on
                    specified call dates. Mortgage pass-through securities
                    provide for monthly payments that are a "pass-through" of
                    the monthly interest and principal payments made by the
                    individual borrowers on the pooled mortgage loans. Mortgage
                    pass-through securities may be collateralized by mortgages
                    with fixed rates of interest or adjustable rates.

                                                                               7

                    BORROWING. In seeking to increase income, the Portfolio may
                    borrow to purchase securities. Such borrowing may not exceed
                    25% of the Portfolio's total assets.

                    OTHER INVESTMENTS. The Portfolio may invest up to 15% of its
                    assets in Yankee corporate bonds which are rated at the time
                    of purchase within the three highest grades as determined by
                    Moody's or S&P or which, if not rated, are of comparable
                    quality as determined by the Investment Manager. Yankee
                    corporate bonds are U.S. dollar denominated debt securities
                    issued by foreign companies.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------

                    There is no assurance that the Portfolio will achieve its
                    investment objectives. The Portfolio's share price and yield
                    will fluctuate with changes in the market value of its
                    portfolio securities. When you sell Portfolio shares, they
                    may be worth less than what you paid for them and,
                    accordingly, you can lose money investing in this Portfolio.


                    A principal risk of investing in the Portfolio is associated
                    with the Portfolio's investments in fixed-income securities.
                    These risks are credit risk and interest rate risk. Credit
                    risk is the possibility that the issuer of a security will
                    be unable to make interest payments and/or repay the
                    principal on its debt. Interest rate risk refers to
                    fluctuations in the value of a fixed-income security
                    resulting from changes in the general level of interest
                    rates.

                    There are also particular risks associated with the
                    Portfolio's investments in mortgage-backed securities. For
                    example mortgage-backed securities are subject to prepayment
                    risk and in some cases may be more volatile and less liquid
                    than other traditional types of debt securities.

                    The Portfolio may borrow money to purchase securities. To
                    the extent that the Portfolio engages in such practice it
                    may be leveraged. Leveraging generally exaggerates the
                    effect on net asset value of any increase or decrease in the
                    market value of the Portfolio's investments.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.

THE HIGH YIELD PORTFOLIO

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The High Yield Portfolio seeks as a primary objective to
                    provide a high level of current income by investing in a
                    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 Portfolio will seek capital
                    appreciation, but only when consistent with its primary
                    objective.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in fixed-income securities (including zero coupon
                    securities) rated Baa or lower by Moody's or BBB or lower by
                    S&P or in nonrated securities considered by the Investment
                    Manager to be appropriate investments for the Portfolio.
                    These securities are commonly known as "junk bonds." They
                    may also include "Rule 144A" securities, which are subject
                    to resale restrictions. There are no minimum quality ratings
                    for investments.

                    In making investment decisions the "Investment Manager,"
                    Morgan Stanley Dean Witter Advisors Inc., considers an
                    issuer's creditworthiness, economic developments, interest
                    rate trends and other factors it deems relevant. In
                    evaluating an issuer's creditworthiness the Investment
                    Manager relies principally on its own analysis. A security's
                    credit rating is simply one factor that may be considered by
                    the Investment Manager in this regard.

                    In addition to junk bonds, the Portfolio may invest in the
                    following:

                    - Higher rated fixed-income securities -- The Portfolio may
                      invest in securities rated higher than Baa or BBB (or if
                      not rated, determined to be of comparable quality) when
                      the Investment Manager believes that such securities may
                      produce attractive yields.

                    - Foreign securities -- The Portfolio may invest up to 20%
                      of its assets in securities issued by foreign governments
                      and other foreign issuers (including American depository
                      receipts or other similar securities convertible into
                      securities of foreign issuers) but not more than 10% of
                      its assets in these securities may be denominated in
                      foreign currencies.

                    - Unit Offerings -- The Portfolio may purchase units which
                      combine debt securities with equity securities and/or
                      warrants.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------

                    There is no assurance that the Portfolio will achieve its
                    investment objectives. The Portfolio's share price and yield
                    will fluctuate with changes in the market value of its
                    portfolio securities. When you sell Portfolio shares, they
                    may be worth less than what you paid for them and,
                    accordingly, you can lose money investing in this Portfolio.


                    A principal risk of investing in the Portfolio is associated
                    with its investments in junk bonds. Junk bonds are subject
                    to greater risk of loss of income and principal than higher
                    rated securities. The prices of junk bonds have been found
                    generally to be less sensitive to changes in prevailing
                    interest rates than higher rated securities but are more

                    likely to be sensitive to adverse economic changes or
                    individual corporate developments. In addition, all
                    fixed-income securities are subject to two types of risk:
                    credit risk and interest rate risk.

                    The Portfolio is subject to the risks associated with
                    foreign securities. These risks include, among other things,
                    the possibility that the Portfolio could be adversely
                    affected by changes in currency exchange rates.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see

GROWTH & INCOME
An investment objective having the goal of selecting securities with the
potential to rise in price and pay out income.
[End Sidebar]

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Utilities Portfolio seeks both capital appreciation and
                    current income.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------

                    The Portfolio will normally invest at least 65% of its total
                    assets in the securities of companies engaged in the
                    utilities industry. These companies are involved in various
                    aspects of the industry, such as communications, and gas and
                    electric energy, but they do not include public broadcasting
                    companies. A company will be considered engaged in the
                    utilities industry if it derives at least 50% of its
                    revenues or earnings from that industry or it devotes at
                    least 50% of its assets to activities in that industry.
                    These may include companies involved in, among other things,
                    telecommunications, computers and other new or emerging
                    technologies, gas and electric energy, water distribution,
                    the Internet and Internet related services. The companies
                    may be traditionally regulated public utilities or fully or
                    partially deregulated utility companies as well as
                    unregulated utility companies.

                    The Portfolio's "Investment Manager," Morgan Stanley Dean
                    Witter Advisors Inc., will shift the Portfolio's assets
                    between different segments of the utilities industry and
                    between common stock, other equity securities and investment
                    grade fixed-income securities based on its view of
                    prevailing market, economic and financial conditions. The
                    Portfolio does not have any set policies to concentrate its
                    assets in any particular segment of the utilities industry
                    or any particular type of security. However, the Portfolio's
                    policy to concentrate its assets in the utilities industry
                    is fundamental, and may not be changed without shareholder
                    approval. In selecting common stock and other equity
                    securities, the Investment Manager considers 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.
                    Computer-based equity selection models also may be used. If
                    the Investment Manager believes favorable conditions for
                    capital growth of equity securities are not prevalent at a
                    particular time, it may allocate the Portfolio's assets
                    predominantly or exclusively to debt securities with the aim
                    of obtaining current income and thus benefitting long-term
                    growth of capital.

                    The Portfolio may invest up to 35% of its assets in U.S.
                    Government securities issued or guaranteed as to principal
                    and interest by the U.S. Government or its agencies or
                    instrumentalities and in real estate investment trusts
                    (commonly known as "REITs").

                    The Portfolio may invest up to 25% of its assets in foreign
                    securities (including depository receipts). This percentage
                    limitation, however, does not apply to securities of foreign
                    companies that are listed in the U.S. on a national
                    securities exchange.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    The Portfolio invests primarily in securities of companies
                    in the utilities industry. The Portfolio's investments in
                    the utilities industry are impacted by a host of risks
                    particular to that industry. Changing regulation constitutes
                    one of the key industry-specific risks for the Portfolio.
                    State and other regulators monitor and control utility
                    revenues and costs, and therefore may limit utility profits
                    and dividends paid to investors. Regulatory authorities also
                    may restrict a company's access to new markets, thereby
                    diminishing the company's long-term prospects. Individual
                    sectors of the utility market are subject to additional
                    risks. These risks apply to all utility companies --
                    regulated, fully or partially deregulated and unregulated.
                    For example, telecommunications companies have been affected
                    by technological development leading to increased
                    competition, as well as changing regulation of local and
                    long-distance telephone service and other telecommunications
                    businesses. Certain telecommunications companies have not
                    benefitted from the new competitive climate.

                    Electric utilities may incur unexpected increases in fuel
                    and other operating costs. They are adversely affected when
                    long-term interest rates rise. Long-term borrowings are used
                    to finance most utility investment and rising interest rates
                    lead to higher financing costs and reduced earnings. There
                    are also the considerable costs associated with
                    environmental compliance, nuclear waste clean-up, and safety
                    regulation. Increasingly, regulators are calling upon
                    electric utilities to bear these added costs, and there is a
                    risk that these costs will not be fully recovered through an
                    increase in revenues.

                    Among gas companies, there has been a move to diversify into
                    oil and gas exploration and development, making investment
                    return more sensitive to energy prices. In the case of the
                    water utility sector, the industry is highly fragmented, and
                    most water supply companies find themselves in mature
                    markets, although upgrading of fresh water and waste water
                    systems is an expanding business.

                    The Portfolio's investments in common stock are also subject
                    to the risks that affect all common stocks. In particular,
                    stock prices can fluctuate widely in response to activities
                    specific to the issuer as well as general market economic
                    and political conditions.

                    The Portfolio's investment in fixed-income securities are
                    subject to credit risk and interest rate risk. Credit risk
                    refers to a possibility that the issuer of a security will
                    be unable to make interest payments and/or repay the
                    principal on its debts. Interest rate risk refers to
                    fluctuations in the value of a fixed-income security
                    resulting from changes in the general level of interest
                    rates.

                                                                              13

                    The Portfolio is subject to the risks associated with
                    foreign securities. These risks include, among other things,
                    the possibility that the Portfolio could be adversely
                    affected by changes in currency exchange rates.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the

THE INCOME BUILDER PORTFOLIO

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The Income Builder Portfolio seeks as a primary objective
                    reasonable income. Growth of capital is the secondary
                    objective.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in income-producing equity securities, including
                    common stock, preferred stock and convertible securities.
                    The "Investment Manager," Morgan Stanley Dean Witter
                    Advisors Inc., uses a value-oriented style in the selection
                    of securities. Investments are normally made primarily in
                    (i) common stocks of large capitalization companies with a
                    record of paying dividends and which in the opinion of the
                    Investment Manager have the potential for maintaining
                    dividends, (ii) preferred stock and (iii) securities
                    convertible into common stocks of small and midcap
                    companies -- including synthetic and enhanced convertibles.
                    The Portfolio's investments may also include "Rule 144A"
                    securities, which are subject to resale restrictions.

                    The Investment Manager follows a "bottom-up" approach in the
                    selection of convertible securities for the Portfolio.
                    Beginning with a universe of about 500 companies, the
                    Investment Manager narrows the focus to small and midcap
                    companies and reviews the issues to determine if the
                    convertible is trading with the underlying equity security.
                    The yield of the underlying equity security is evaluated and
                    company fundamentals are studied to evaluate cash flow,
                    risk/reward balance, valuation and the prospects for growth.

                    The Portfolio may invest up to 25% of its assets in
                    "enhanced" convertible securities. Enhanced convertible
                    securities offer holders the opportunity to obtain higher
                    current income than would be available from a traditional
                    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.

                    The Portfolio may invest up to 10% of its 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.

                                                                              15
<PAGE>
                    The Portfolio may invest up to 20% of its assets in
                    fixed-income securities rated lower than investment grade by
                    S&P or Moody's (but not below B) or if unrated of comparable
                    quality as determined by the Investment Manager (commonly
                    known as "junk bonds"). The 20% limitation is not applicable
                    to convertible securities.

                    The Portfolio may invest up to 35% of its assets in U.S.
                    Government securities issued or guaranteed as to principal
                    and interest by the U.S. Government or its agencies or
                    instrumentalities and investment grade fixed-income
                    securities (including zero coupon securities), common stocks
                    that do not pay a regular dividend and real estate
                    investment trusts (commonly known as "REITs").

                    The Portfolio may invest up to 25% of its assets in foreign
                    securities (including depository receipts). This percentage
                    limitation, however, does not apply to securities of foreign
                    companies that are listed in the U.S. on a national
                    securities exchange.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objectives. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investing in the Portfolio is associated
                    with its investment in common stocks. In particular the
                    prices of common stocks can fluctuate widely in response to
                    activities specific to the issuer as well as general market,
                    economic and political conditions.

                    The Portfolio is also subject to the risks of investing in
                    convertible securities. These securities may carry risks
                    associated with both common stock and fixed-income
                    securities. In addition, because the convertible securities
                    in which the Portfolio invests are convertible into the
                    common stocks of small and midcap companies, the Portfolio
                    is subject to the specific risks associated with investing
                    in small and midcap companies. Investments in small and
                    medium capitalization companies involve greater risk of
                    volatility than is customarily associated with investments
                    in more established companies as well as certain other
                    additional risks.

                    There are also special risks associated with the Portfolio's
                    investments in "enhanced" and "synthetic" convertible
                    securities. These securities may be more volatile and less
                    liquid than traditional convertible securities.

                    The Portfolio is subject to the risks associated with
                    foreign securities. These risks include, among other things,
                    the possibility that the Portfolio could be adversely
                    affected by changes in currency exchange rates.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see

[End Sidebar]

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The Dividend Growth Portfolio seeks to provide reasonable
                    current income and long term growth of income and capital.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will invest at least 70% of its total assets
                    in common stock of companies with a record of paying
                    dividends and the potential for increasing dividends. The
                    "Investment Manager," Morgan Stanley Dean Witter Advisors
                    Inc., initially employs a quantitative screening process in
                    an attempt to develop a number of common stocks which are
                    undervalued and which have a record of paying dividends. The
                    Investment Manager then applies qualitative analysis to
                    determine which stocks it believes have the potential to
                    increase dividends and, finally, to determine whether any of
                    the stocks should be added to the Portfolio. The Investment
                    Manager attempts to avoid investment in speculative
                    securities or those with speculative characteristics.

                    The Portfolio may invest up to 30% of its assets in
                    convertible securities, U.S. Government securities issued or
                    guaranteed as to principal and interest by the U.S.
                    Government, its agencies or instrumentalities, and
                    investment grade fixed-income securities (including zero
                    coupon securities). The Portfolio may also invest any amount
                    of its assets in foreign securities (including depository
                    receipts) that are listed in the U.S. on a national
                    securities exchange.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objectives. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investing in the Portfolio is associated
                    with its investments in common stock. In particular the
                    prices of common stock may fluctuate widely in response to
                    activities specific to the company as well as general
                    market, economic and political conditions.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the

THE CAPITAL GROWTH PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Capital Growth Portfolio seeks long term capital growth.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in common stocks. The "Investment Manager," Morgan
                    Stanley Dean Witter Advisors Inc., utilizes a two-stage
                    computerized screening process designed to find companies
                    that demonstrate a history of consistent growth in earnings
                    and revenues over the past several years, and have solid
                    future earnings growth characteristics and attractive
                    valuations. Dividend income is not a consideration in this
                    stock selection process. Companies meeting these
                    requirements are potential candidates for investment by the
                    Portfolio. The Investment Manager may modify the screening
                    process and/or may utilize additional or different screening
                    processes in connection with the Portfolio's investments.

                    The Portfolio may invest up to 35% of its assets in U.S.
                    Government securities issued or guaranteed as to principal
                    and interest by the U.S. Government or its agencies or
                    instrumentalities, investment grade fixed-income securities
                    (including zero coupon securities), convertible securities,
                    unit offerings involving a combination of a debt security
                    and a convertible security and/or warrant and real estate
                    investment trusts (commonly known as "REITs").

                    The Portfolio may invest up to 25% of its assets in foreign
                    securities (including depository receipts). This percentage
                    limitation, however, does not apply to securities of foreign
                    companies that are listed in the U.S. on a national
                    securities exchange.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common stock.
                    In particular the prices of common stocks may fluctuate
                    widely in response to activities specific to the company as
                    well as general market, economic and political conditions.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.

THE GLOBAL DIVIDEND GROWTH PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Global Dividend Growth Portfolio seeks to provide
                    reasonable current income and long term growth of income and
                    capital.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in dividend paying equity securities issued by
                    issuers located in various countries around the world. The
                    "Investment Manager," Morgan Stanley Dean Witter Advisors
                    Inc., seeks investments primarily in common stock of
                    companies with a record of paying dividends and potential
                    for increasing dividends. The Portfolio invests in at least
                    three separate countries. The percentage of 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 Portfolio's assets may be invested as
                    follows:

                    - Convertible securities, U.S. Government securities issued
                      or guaranteed as to principal and interest by the U.S.
                      Government, its agencies or instrumentalities,
                      fixed-income securities issued by foreign governments and
                      international organizations and investment grade debt
                      securities (including zero coupon securities).

                    - Forward currency contracts, which involve the purchase or
                      sale of a specific amount of foreign currency at a
                      specified price with delivery at a specified future date.
                      The Portfolio may use these contracts to hedge against
                      adverse price movements in its portfolio securities and
                      the currencies in which they are denominated.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of Investment in the Portfolio is
                    associated with the Portfolio's investments in common
                    stocks. In particular, the price of common stocks may
                    fluctuate widely in response to activities specific to the
                    company as well as general market, economic and political
                    conditions.

                    Another principal risk relates to the Portfolio's
                    investments in foreign securities. In particular, foreign
                    security investments may be adversely affected by changes in
                    currency exchange rates. In addition, investments in foreign
                    securities may be adversely affected by among other things
                    political, social and economic developments abroad.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.

                    information about the risks summarized in this section, see

THE EUROPEAN GROWTH PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The European Growth Portfolio seeks to maximize the capital
                    appreciation of its investments.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in securities issued by issuers located in European
                    countries. A company is considered located in Europe if
                    (i) it is organized under the laws of a European country and
                    has a principal office in a European country; (ii) it
                    derives at least 50% of its total revenue from business in
                    Europe; or (iii) the company's equity securities are traded
                    principally on a stock exchange in Europe. The principal
                    countries in which the Portfolio invests are France, the
                    United Kingdom, Germany, the Netherlands, Spain, Sweden,
                    Switzerland and Italy. The Portfolio invests in at least
                    three separate countries.

                    The Portfolio generally invests principally in equity
                    securities (which may include depository receipts or
                    convertible securities) but may also invest without
                    limitation in fixed-income securities issued or guaranteed
                    by European governments when the "Investment Manager,"
                    Morgan Stanley Dean Witter Advisors Inc., or the "Sub-
                    Advisor," Morgan Stanley Dean Witter Investment Management
                    Inc., determine such investments to be appropriate.

                    The Investment Manager and the Sub-Advisor generally invest
                    Portfolio assets in companies they believe have a high rate
                    of earnings growth potential. They also select securities,
                    which in their view, possess, both on an absolute basis and
                    as compared with other securities around the world,
                    attractive price/earnings, price/ cash flow and
                    price/revenue ratios.

                    The Portfolio may invest up to 35% of its assets as follows:

                    - Equity securities issued by non-European issuers, and
                      government and convertible securities issued by
                      non-European governmental or private issuers.

                    - Forward currency contracts, which involve the purchase or
                      sale of a specific amount of foreign currency at the
                      current price with delivery at a specified future date.
                      The Portfolio may use these contracts to hedge against
                      adverse price movements in its portfolio securities and
                      securities it intends to purchase and the currencies in
                      which they are denominated.


                    The Portfolio may invest up to 5% of its assets in put and
                    call options with respect to foreign currencies. The
                    Portfolio may also purchase and sell stock index futures
                    contracts and options thereon. Stock index futures and
                    options thereon may be used to facilitate trading, to
                    increase the Portfolio's market exposure or to seek to
                    protect against an increase in the prices of securities that
                    may be purchased.


                    The Portfolio may invest in warrants and acquire warrants
                    attached to other securities.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk factor associated with investment in the
                    Portfolio relates to the Portfolio's investments in Europe.
                    In particular, adverse political, social or economic
                    developments in Europe, or in a particular European country,
                    could cause a substantial decline in the value of the
                    Portfolio.

                    The Portfolio's investments in common stock are also subject
                    to the risks that affect all common stocks. In particular,
                    stock prices can fluctuate widely in response to activities
                    specific to the issuer as well as general market economic
                    and political conditions.

                    The conversion to a single European currency by many
                    European countries could potentially adversely affect the
                    value and/or increase the volatility of the Portfolio's
                    investments.

                    In addition, the Portfolio is subject to the risks
                    associated with foreign securities generally. These risks
                    include, among other things, the possibility that the
                    Portfolio could be adversely affected by changes in currency
                    exchange rates.

                    In addition, the Portfolio's investments in fixed-income
                    securities are subject to two types of risk: credit risk and
                    interest rate risk.

                    The Portfolio is also subject to the risks of investing in
                    convertible securities. These securities may carry risks
                    associated with both common and fixed-income securities.

                    The performance of the Portfolio also will depend on whether
                    the Sub-Advisor is successful in pursuing the Portfolio's
                    investment strategy. In addition, the Portfolio is subject
                    to other risks from its permissible investments. For
                    information about these risks, as well as more detailed
                    information about the risks summarized in this section, see

THE PACIFIC GROWTH PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Pacific Growth Portfolio seeks to maximize the capital
                    appreciation of its investments.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in common stocks (including depository receipts) and
                    other securities of companies which are (i) organized under
                    the laws of and have a principal place of business in Asia,
                    Australia or New Zealand or (ii) derives at least 50% of
                    their total revenues from business in such areas. The
                    principal Asian countries include: Japan, Malaysia,
                    Singapore, Hong Kong, Thailand, the Philippines, India,
                    Indonesia, Taiwan and South Korea. The Portfolio's assets
                    are invested in at least three countries. The Portfolio may
                    invest more than 25% of its assets in Japan, Hong Kong,
                    South Korea and Taiwan. Thus, the investment performance of
                    the Portfolio may be subject to the social, political and
                    economic events occurring in these countries to a greater
                    extent than other countries.

                    The "Investment Manager," Morgan Stanley Dean Witter
                    Advisors Inc., and the "Sub-Advisor," Morgan Stanley Dean
                    Witter Investment Management Inc., generally invest
                    Portfolio assets in companies they believe have a high rate
                    of earnings growth potential. They also select securities,
                    which in their view, possess, both on an absolute basis and
                    as compared with other securities around the world,
                    attractive price/earnings, price/cash flow and price/revenue
                    ratios.

                    The Portfolio generally invests principally in equity
                    securities but may also invest without limitation in
                    fixed-income obligations issued or guaranteed by an Asian
                    country or Australia or New Zealand when the Investment
                    Manager or the Sub-Advisor determine such investments to be
                    appropriate.

                    The Portfolio may invest up to 35% of its assets as follows:

                    - Equity, fixed-income or convertible securities (including
                      zero coupon securities) of companies located anywhere in
                      the world, including the United States.

                    - Forward currency contracts, which involve the purchase or
                      sale of a specific amount of foreign currency at the
                      current price with a delivery at a specified future date.
                      The Portfolio may use these contracts to hedge against
                      adverse price movements in its portfolio securities and
                      securities it intends to purchase and the currencies in
                      which they are denominated.

                    The Portfolio may invest up to 5% of its assets in put and
                    call options with respect to foreign currencies.

                    The Portfolio may invest up to 10% of its assets in
                    securities issued by other investment companies. The
                    Investment Manager and/or Sub-Advisor may view these
                    investments as necessary or advisable to participate in
                    certain foreign markets where foreigners are prohibited from
                    investing directly in the securities of individual companies
                    without regulatory approval.

                                                                              27
<PAGE>
                    The Portfolio may invest in warrants and acquire warrants
                    attached to other securities.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio relates to
                    the Portfolio's investments in the Pacific region. In
                    particular, adverse political, social or economic
                    developments in the Pacific region or in a particular
                    Pacific country could cause a substantial decline in the
                    value of the Portfolio.

                    The Portfolio's investments in common stock are also subject
                    to the risks that affect all common stocks. In particular,
                    stock prices can fluctuate widely in response to activities
                    specific to the issuer as well as general market economic
                    and political conditions.

                    In addition, the Portfolio is subject to the risks
                    associated with foreign securities generally. These risks
                    include among other things the possibility that the
                    Portfolio could be adversely affected by changes in currency
                    exchange rates. The Portfolio may invest a substantial
                    portion of its assets in developing countries. These
                    investments carry greater risks than those associated with
                    investment in more developed countries.

                    In addition, the Portfolio's investments in fixed-income
                    securities are subject to two types of risk: credit risk and
                    interest rate risk.

                    The performance of the Portfolio also will depend on whether
                    the Sub-Advisor is successful in pursuing the Portfolio's
                    investment strategy. In addition, the Portfolio is subject
                    to other risks from its permissible investments. For
                    information about these risks, as well as more detailed
                    information about the risks summarized in this section, see

THE EQUITY PORTFOLIO

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The Equity Portfolio seeks as a primary objective growth of
                    capital through investments in common stocks of companies
                    believed by the Investment Manager to have potential for
                    superior growth. As a secondary objective the Equity
                    Portfolio seeks income but only when consistent with its
                    primary objective.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in equity securities and securities convertible into
                    equity securities. In selecting investments, the "Investment
                    Manager," Morgan Stanley Dean Witter Advisors Inc., may
                    employ valuation models based on various economic and market
                    indicators. The Investment Manager currently utilizes a
                    process, known as sector rotation, that emphasizes industry
                    selection over individual company selection. The Investment
                    Manager invests in those industries that it believes will
                    have the strongest relative earnings growth potential given
                    the projected economic outlook. After selecting the
                    Portfolio's target industries, the Investment Manager then
                    selects specific companies within those industries whose
                    prospects are deemed attractive after assessing company
                    fundamentals and valuation screens.

                    The Investment Manager utilizes a sector rotation process
                    designed to respond to changing economic cycles by
                    proactively investing in industries that the Investment
                    Manager believes to be positioned to benefit from the
                    current phase of the economic cycle. First, the Investment
                    Manager attempts to identify at what stage of the business
                    cycle the economy is in and which industries have
                    historically outperformed the overall market during that
                    stage of the cycle. To accomplish that task, the Investment
                    Manager establishes an economic forecast based on its short
                    term and long term views of the domestic and global economic
                    cycles. As part of this process, the Investment Manager will
                    attempt to identify secular trends, such as shifting
                    demographics or technological developments, that could add
                    clarity to its analysis. Also considered are competitive
                    industry variables, such as supply and demand, pricing
                    trends and new product cycles.

                    The Portfolio may invest up to 35% of its assets in
                    corporate debt securities (including zero coupon securities)
                    rated Aa or better by Moody's or AA or better by S&P, U.S.
                    Government securities, issued or guaranteed as to principal
                    and interest by the U.S. Government, its agencies or
                    instrumentalities, and preferred stocks.

                    The Portfolio may invest in securities of Canadian issuers
                    registered under the Securities Exchange Act of 1934 or
                    American Depository Receipts.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objectives. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common stock.
                    In particular the price of common stocks may fluctuate
                    widely in response to activities specific to the company as
                    well as general market, economic and political conditions.
                    Stocks of small and medium capitalization companies in which
                    the Portfolio may invest pose greater risk of volatility
                    than is customarily associated with larger established
                    companies as well as certain other additional risks.

                    Another principal risk relates to the Portfolio's
                    investments in fixed-income securities. Fixed-income
                    securities involve credit risk and interest rate risk.
                    Credit risk relates to the possibility that an issuer could
                    default on its obligation to pay principal and/or interest.
                    Interest rate risk relates to the possibility that the value
                    of securities may be adversely affected by fluctuations in
                    interest rates.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.

THE S&P 500 INDEX PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    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
                    Standard & Poor's-Registered Trademark- 500 Composite Stock
                    Price Index.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------

                    The Portfolio will normally invest at least 80% of its total
                    assets in common stocks included in the S&P 500 Index. The
                    "Investment Manager," Morgan Stanley Dean Witter Advisors
                    Inc., "passively" manages the Portfolio's assets by
                    investing in stocks in approximately the same proportion as
                    they are represented in the S&P 500 Index. For example,
                    where the common stock of a specific company represents five
                    percent of the Index, the Investment Manager typically will
                    invest five percent of the Portfolio's assets in that stock.
                    The S&P 500 Index is a well-known stock market index that
                    includes common stocks of 500 companies representing a
                    significant portion of the market value of all common stocks
                    publicly traded in the United States.

                    The Portfolio may purchase and sell stock index futures to
                    simulate investment in the S&P 500. Generally stock index
                    futures may be employed to provide liquidity necessary to
                    meet anticipated redemptions or for day-to-day operating
                    purposes.

                    The Portfolios may invest in securities referred to as SPDRs
                    (known as "spiders") that are designed to track the S&P 500
                    Index. SPDRs represent an ownership interest in the SPDR
                    Trust, which holds a portfolio of common stocks that closely
                    tracks the price performance and dividend yield of the S&P
                    500 Index. SPDRs trade on the American Stock Exchange like
                    shares of common stock. The Portfolio may invest up to 10%
                    of its total assets in the aggregate in SPDRs.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

<PAGE>
                    A principal risk of investing in the Portfolio is associated
                    with its common stock investments. In general, stock values
                    fluctuate in response to activities specific to the issuer,
                    as well as general market, economic and political
                    conditions. Stock prices can fluctuate widely in response to
                    these factors.

                    Another risk of investing in the Portfolio arises from its
                    operation as a "passively" managed index fund. As such, the
                    adverse performance of a particular stock ordinarily will
                    not result in the elimination of the stock from the
                    Portfolio. The Portfolio will remain invested in common
                    stocks even when stock prices are generally falling.
                    Ordinarily, the Investment Manager will not sell the
                    Portfolio's securities except to reflect additions or
                    deletions of the stocks that comprise the S&P 500 Index, or
                    as may be necessary to raise cash to pay Portfolio
                    shareholders who sell (redeem) Portfolio shares.

                    The performance of the S&P 500 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 Portfolio and any
                    incremental operating costs borne by the Portfolio (E.G.,
                    management fee, transfer agency and accounting costs).
                    Accordingly, the performance of the Portfolio may not
                    correlate directly with the performance of the S&P 500
                    Index.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.

THE COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Competitive Edge "Best Ideas" Portfolio seeks long-term
                    capital growth.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 80% of its total
                    assets in common stock of companies included in the "Best
                    Ideas" subgroup of "Global Investing: The Competitive Edge,"
                    a research compilation assembled by Morgan Stanley Dean
                    Witter ("MSDW") Equity Research -- and other securities
                    selected by the Portfolio's "Investment Manager," Morgan
                    Stanley Dean Witter Advisors Inc.

                    THE COMPETITIVE EDGE "BEST IDEAS" LIST. 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.


                    MSDW Equity Research group's research analysts and
                    strategists presently evaluate approximately 2,100 companies
                    in 21 industry sectors worldwide. An initial comprehensive
                    review was conducted in October 1996 and identified 238 of
                    these companies 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
                    quarterly. From the Competitive Edge List, MSDW Equity
                    Research then assembles a subgroup of approximately 40
                    companies which it considers 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"). The Competitive Edge "Best Ideas" List is
                    updated continuously.


                    It is the intention of the Investment Manager that generally
                    at least 1% and not more than 5% of the Portfolio's assets
                    will be invested in each company on the Competitive Edge
                    "Best Ideas" List. The Portfolio will purchase any security
                    which is added to the Competitive Edge "Best Ideas" List,
                    and generally will sell a security which is eliminated from
                    the Competitive Edge "Best Ideas" List as soon as
                    practicable after the Competitive Edge "Best Ideas" List has
                    been updated by MSDW Equity Research. Accordingly,
                    securities may be purchased and sold by the Portfolio when
                    such purchases and sales would not be made under traditional
                    investment criteria.

                    The Portfolio may at times purchase securities that are not
                    included on the Competitive Edge "Best Ideas" List but are
                    on the Competitive Edge List or, in the event that the
                    Investment Manager believes that there are no suitable
                    securities on the Competitive Edge List, the Portfolio may
                    purchase securities outside the list. Securities that are

                    The Portfolio's investments may include forward currency
                    contracts which involve the purchase or sale of a specific
                    amount of foreign currency at a specified price with
                    delivery at a specified future date. The Portfolio may use
                    these contracts to hedge against adverse price movements in
                    its portfolio securities and the currencies in which they
                    are denominated.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common
                    stocks. In particular the prices of common stocks may
                    fluctuate widely in response to activities specific to the
                    company as well as general market, economic and political
                    conditions.

                    The Portfolio invests principally in securities included on
                    the Competitive Edge "Best Ideas" List which currently
                    consists of 40 companies. As a result of the small universe
                    of stocks in which the Portfolio invests it may be subject
                    to greater risks than would a more diversified company. At
                    times the Portfolio may be restricted in its ability to
                    purchase or sell securities on the Competitive Edge "Best
                    Ideas" List as a result of activities of affiliates of the
                    Investment Manager. In addition, performance of the
                    securities included in the List cannot be used to predict
                    the performance of the Portfolio, an actively managed mutual
                    fund.

                    The Competitive Edge "Best Ideas" List is not compiled with
                    any particular client or product in mind and is not, and
                    will not be, compiled with the Portfolio in mind. When
                    selecting the companies for the list, MSDW Equity Research
                    does not take into account country or currency risks, 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 Equity Research could at any time cease
                    publishing the Competitive Edge "Best Ideas" List. In that
                    event the Board of Trustees will make a determination of how
                    to proceed in the best interest of shareholders of the
                    Portfolio consistent with the Portfolio's investment
                    objective.

                    The activities of affiliates of the Investment Manager,
                    including but not limited to Dean Witter Reynolds Inc. or
                    Morgan Stanley & Co. Incorporated, may from time to time
                    limit the Portfolio's ability to purchase or sell securities
                    on the Competitive Edge "Best Ideas" List. In addition, the
                    List is available to other clients of MSDW and its
                    affiliates, including the Investment Manager, as well as the
                    Portfolio. The list is also subject to restrictions related
                    to MSDW's other businesses, and particular securities may or
                    may not be on the list due to other business concerns of, or
                    legal restrictions applicable to, MSDW.

                    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

                    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 Portfolio may invest a substantial portion of its assets
                    in foreign securities. Foreign securities investments may be
                    adversely affected by changes in currency exchange rates. In
                    addition, investment in foreign securities may be adversely
                    affected by among other things political, social and
                    economic developments abroad.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see

THE AGGRESSIVE EQUITY PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Aggressive Equity Portfolio seeks long-term capital
                    growth.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in common stocks and other equity securities of
                    companies that the "Investment Manager," Morgan Stanley Dean
                    Witter Advisors Inc., believes offer the potential for
                    superior earnings growth. The Portfolio's other equity
                    securities may include preferred stocks, securities
                    convertible into common stock, rights and warrants. No more
                    than 25% of the Portfolio's assets may be invested in
                    foreign equity or fixed-income securities denominated in a
                    foreign currency and traded primarily in non-U.S. markets.

                    The Investment Manager utilizes a process, known as sector
                    rotation, that emphasizes industry selection over individual
                    company selection. The Investment Manager invests in those
                    industries that it believes will have the strongest relative
                    earnings growth potential given the projected economic
                    outlook. After selecting the Portfolio's target industries,
                    the Investment Manager selects specific companies within
                    those industries whose prospects are deemed attractive after
                    assessing company fundamentals and valuation screens.
                    Company selection is based on the Investment Manager's own
                    analysis and research reports as well as analysis from the
                    equity research departments of recognized securities firms.
                    The Investment Manager has no general criteria as to the
                    market capitalization or asset size of the companies
                    selected for investment and, accordingly, the Portfolio may
                    invest in small and medium-sized companies in addition to
                    larger, more established companies.

                    The Investment Manager utilizes a sector rotation process
                    designed to respond to changing economic cycles by
                    proactively investing in industries that the Investment
                    Manager believes to be positioned to benefit from the
                    current phase of the economic cycle. First, the Investment
                    Manager attempts to identify at what stage of the business
                    cycle the economy is in and which industries have
                    historically outperformed the overall market during that
                    stage of the cycle. To accomplish that task, the Investment
                    Manager establishes an economic forecast based on its short
                    term and long term views of the domestic and global economic
                    cycles. As part of this process, the Investment Manager will
                    attempt to identify secular trends, such as shifting
                    demographics or technological developments, that could add
                    clarity to its analysis. Also considered are competitive
                    industry variables, such as supply and demand, pricing
                    trends and new product cycles.

                    The Portfolio may invest up to 35% of its assets as follows:

                    - (a) fixed-income securities of U.S. companies,
                      (b) fixed-income securities of foreign companies and
                      governments and international organizations, (c) U.S.
                      Government securities, issued or guaranteed as to
                      principal and interest by the U.S. Government, its
                      agencies or instrumentalities, and (d) real estate
                      investment trusts (commonly known as "REITs"). However, no
                      more than 5% of the

                                                                              39
<PAGE>
                      Portfolio's assets may be invested in debt securities
                      rated lower than investment grade, or if unrated of
                      comparable quality as determined by the Investment Manager
                      (commonly known as "junk bonds").

                    - Forward currency contracts, which involve the purchase or
                      sale of a specific amount of foreign currency at a
                      specified price with delivery at a specified future date.
                      The Portfolio may use these contracts to hedge against
                      adverse price movements in its portfolio securities and
                      the currencies in which they are denominated.

                    - Put and call options and futures with respect to financial
                      instruments, stock and interest rate indexes and foreign
                      currencies (limit of 5% of its assets for the purchase of
                      put and call options). Options and futures may be used to
                      seek higher returns or to seek to protect against a
                      decline in security or currency prices or an increase in
                      prices of securities or currencies that may be purchased.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common
                    stocks. In particular, the prices of common stocks may
                    fluctuate widely in response to activities specific to the
                    company as well as general market, economic and political
                    conditions.

                    The Portfolio may invest a substantial portion of its assets
                    in securities issued by small and medium sized companies.
                    Investment in small and medium size companies involves
                    greater risk of volatility than is customarily associated
                    with investment in larger established companies as well as
                    certain other additional risks.

                    The Portfolio is subject to the risks associated with
                    foreign securities. These risks include, among other things,
                    the possibility that the Portfolio could be adversely
                    affected by changes in currency exchange rates.

                    The Portfolio is also subject to the risks of investing in
                    convertible securities. These securities may carry risks
                    associated with both common stock and fixed-income
                    securities.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.


                    The Portfolio commenced operations on May 3, 1999 and prior
                    to the date of this PROSPECTUS did not have a full calendar
                    year of performance to report.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES

--------------------------------------------------------------------------------

                    The Portfolio will normally invest at least 65% of its total
                    assets in common stocks and investment grade convertible
                    securities of companies located throughout the world that
                    are engaged in the communications and information industry.
                    The Portfolio normally holds common stocks and other equity
                    securities of companies located in at least three countries,
                    one of which is the United States. It may invest up to 50%
                    of its assets in the securities (including depository
                    receipts) of foreign companies; however, it will not invest
                    more than 25% of its assets in any one foreign country. In
                    addition, the Portfolio will not invest more than 10% of its
                    assets in convertible securities. In deciding which
                    securities to buy, hold or sell, the "Investment Manager,"
                    Morgan Stanley Dean Witter Advisors Inc., considers
                    business, economic and political conditions.



                    A company is considered to be in the communications and
                    information industry if it derives at least 35% of its
                    revenues or earnings from, or devotes at least 35% of its
                    assets to:



                    - designing, developing, manufacturing, providing or
                      enabling the following products and services: regular
                      telephone service; communications equipment and services;
                      electronic components and equipment; broadcasting;
                      computer equipment, enabling software, mobile
                      communications and cellular radio/paging; electronic mail
                      and other electronic data transmission services;
                      networking and linkage of word and data processing
                      systems; publishing and information systems; video text
                      and teletext; and emerging technologies combining
                      telephone, television and/or computer systems; or



                    - the creation, packaging, distribution, and ownership of
                      entertainment and information programming.



                    The Portfolio may invest up to 35% of its total assets in
                    investment grade corporate fixed-income securities and U.S.
                    government securities. The Portfolio's fixed-income
                    investments may include zero coupon securities.



[ICON]              SUMMARY OF PRINCIPAL RISKS

--------------------------------------------------------------------------------

                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.



                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common
                    stocks. In particular, the prices of common stocks may
                    fluctuate widely in response to activities specific to the
                    company as well as general market, economic and political
                    conditions.


                                                                              41
<PAGE>

                    The Portfolio concentrates its investments in the
                    communications and information industry. Because of this
                    concentration, the value of the Portfolio's shares may be
                    more volatile than that of mutual funds that do not
                    similarly concentrate their investments. The communications
                    and information industry may be subject to greater changes
                    in governmental policies and governmental regulation than in
                    many other industries in the United States and worldwide.
                    Regulatory approval requirements, ownership restrictions and
                    restrictions on rates of return and types of services that
                    may be offered may materially affect the products and
                    services of this industry. Additionally, the products and
                    services of companies in this industry may be subject to
                    faster obsolescence as a result of greater competition,
                    advancing technological developments, and changing market
                    and consumer preferences. As a result, the securities of
                    companies in this industry may exhibit greater price
                    volatility than those of companies in other industries.



                    The Portfolio is subject to the risks associated with
                    foreign securities. These risks include, among other things,
                    the possibility that the Portfolio could be adversely
                    affected by changes in currency exchange rates.



                    The Portfolio is also subject to the risks of investing in
                    convertible securities. These securities may carry risks
                    associated with both common stock and fixed-income
                    securities.



                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.



                    The Portfolio was recently organized and as of the date of
                    this PROSPECTUS had no historical performance to report.

THE STRATEGIST PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Strategist Portfolio seeks 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.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------

                    The "Investment Manager," Morgan Stanley Dean Witter
                    Advisors Inc., will actively allocate the Portfolio's assets
                    among the major asset categories of equity securities,
                    fixed-income securities and money market instruments. Assets
                    are allocated by the Investment Manager based on among other
                    things, its assessment of economic and market trends on
                    different sectors of the market. There is no limit as to the
                    percentage of assets that may be allocated to any one asset
                    class. The Investment Manager does not, however, currently
                    intend to write covered call or put options.

                    Within the equity sector, the Investment Manager actively
                    allocates funds to those economic sectors it expects to
                    benefit from major trends and to individual stocks which it
                    considers to have superior investment potential.

                    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, including short-term and
                    intermediate-term bonds.

                    Within the money market sector of the market, the Investment
                    Manager seeks to maximize returns by exploiting spreads
                    among short-term instruments.

                    Securities in which the Portfolio may invest include common
                    stocks, preferred stocks, convertible securities, investment
                    grade debt securities (including zero coupon securities),
                    U.S. Government securities, real estate investment trusts
                    (commonly known as "REITs") and money market instruments.
                    The Portfolio is not limited as to the maturities of the
                    U.S. government securities and other debt securities in
                    which it may invest.

                    The Portfolio may invest up to 20% of its assets in
                    securities issued by foreign governments and foreign private
                    issuers but not more than 10% of its assets in securities
                    denominated in a foreign currency.

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common
                    stocks. In particular, the prices of common stocks may

                    conditions.

                    The Portfolio's investment in fixed-income securities are
                    subject to credit risk and interest rate risk. Credit risk
                    refers to a possibility that the issuer of a security will
                    be unable to make interest payments and/or repay the
                    principal on its debts. Interest rate risk refers to
                    fluctuations in the value of a fixed-income security
                    resulting from changes in the general level of interest
                    rates.

                    The Portfolio is also subject to the risks of investing in
                    convertible securities. These securities may carry risks
                    associated with both common stock and fixed-income
                    securities.

ADDITIONAL INVESTMENT STRATEGY INFORMATION

                    This section provides additional information relating to
                    each Portfolio's principal strategies.

                    INVESTMENT DISCRETION. In pursuing each Portfolio's
                    investment objective, the Investment Manager has
                    considerable leeway in deciding which investments it buys,
                    holds or sells on a day-to-day basis - and which trading
                    strategies it uses. For example, the Investment Manager in
                    its discretion may determine to use some permitted trading
                    strategies while not using others. The Sub-Advisor has a
                    similar degree of discretion.

                    DEFENSIVE INVESTING. Each Portfolio (other than the Money
                    Market Portfolio and the S&P 500 Index Portfolio) may take
                    temporary "defensive" positions in attempting to respond to
                    adverse market conditions. Each Portfolio may invest any
                    amount of its assets in cash or money market instruments in
                    a defensive posture when the Investment Manager or
                    Sub-Advisor, as the case may be, believes it advisable to do
                    so. Although taking a defensive posture is designed to
                    protect the Portfolio from an anticipated market downturn,
                    it could have the effect of reducing the benefit of an
                    upswing in the market. When a Portfolio takes a defensive
                    position, it may not achieve its investment objective(s).

                    INVESTMENT POLICIES. The percentage limitations relating to
                    the composition of a Portfolio apply at the time a Portfolio
                    acquires an investment and refer to the Portfolio's net
                    assets, unless otherwise noted. Subsequent percentage
                    changes that result from market fluctuations will not
                    require a Portfolio to sell any Portfolio security. A
                    Portfolio may change its principal investment strategies
                    without shareholder approval; however you would be notified
                    of any change.


                    PORTFOLIO TURNOVER. Each Portfolio, other than the S&P 500
                    Index Portfolio and the Competitive Edge "Best Ideas"
                    Portfolio, may engage in active and frequent trading of its
                    portfolio securities. The Financial Highlights Table at the
                    end of this PROSPECTUS shows recent portfolio turnover rates
                    for each Portfolio (other than the Information Portfolio,
                    which prior to the date of this PROSPECTUS had not commenced
                    operations). A portfolio turnover rate of 200%, for example,
                    is equivalent to the Portfolio buying and selling all of its
                    securities two times during the course of the year. A high
                    portfolio turnover rate (over 100%) could result in high
                    brokerage costs.

ADDITIONAL RISK INFORMATION

                    This section provides additional information relating to the
                    principal risks of investing in the Portfolios.

                    Shares of the Portfolios are not bank deposits and are not
                    guaranteed or insured by the FDIC or any other government
                    agency.

                                            *    *    *

                    The risks set forth below are applicable to a Portfolio only
                    to the extent the Portfolio invests in the investment
                    described. See "The Portfolios" for a description of the
                    investments which each Portfolio may make.

                    FIXED-INCOME SECURITIES. All fixed-income securities are
                    subject to two types of risk: credit risk and interest rate
                    risk. Credit risk refers to the possibility that the issuer
                    of a security will be unable to make interest payments
                    and/or repay the principal on its debt.

                    Interest rate risk refers to fluctuations in the value of a
                    fixed-income security resulting from changes in the general
                    level of interest rates. When the general level of interest
                    rates goes up, the prices of most fixed-income securities go
                    down. When the general level of interest rates goes down,
                    the prices of most fixed-income securities go up. (Zero
                    coupon securities are typically subject to greater price
                    fluctuations than comparable securities that pay interest.)
                    Accordingly, a rise in the general level of interest rates
                    may cause the price of a Portfolio's fixed-income securities
                    to fall substantially. As merely illustrative of the
                    relationship between fixed-income securities and interest
                    rates, the following table shows how interest rates affect
                    bond prices.

</TABLE>

                    Coupons reflect yields on Treasury securities as of
                    December 31, 1999. The table is not representative of price
                    changes for mortgage-backed securities principally because
                    of prepayments, and it is not representative of junk bonds.
                    In addition, the table is an illustration and does not
                    represent expected yields or share price changes of any
                    Morgan Stanley Dean Witter mutual fund.

                    MORTGAGE-BACKED SECURITIES. Mortgage-backed securities have
                    different risk characteristics than traditional debt
                    securities. Although generally the value of fixed-income
                    securities increases during periods of falling interest
                    rates and decreases during periods of rising interest rates,
                    this is not always the case with mortgage-backed securities.
                    This is due to the fact that principal on underlying
                    mortgages may be prepaid at any time as well as other
                    factors. Generally, prepayments will increase during a
                    period of falling interest rates and decrease during a
                    period of rising interest rates. The rate of prepayments
                    also may be influenced by economic

                                                                              47
<PAGE>
                    and other factors. Prepayment risk includes the possibility
                    that, as interest rates fall, securities with stated
                    interest rates may have the principal prepaid earlier than
                    expected, requiring the Fund to invest the proceeds at
                    generally lower interest rates.

                    Investments in mortgage-backed securities are made based
                    upon, among other things, expectations regarding the rate of
                    prepayments on underlying mortgage pools. Rates of
                    prepayment, faster or slower than expected by the Investment
                    Manager, could reduce a Portfolio's yield, increase the
                    volatility of the Portfolio and/ or cause a decline in net
                    asset value. Certain mortgage-backed securities in which a
                    Portfolio may invest may be more volatile and less liquid
                    than other traditional types of debt securities.

                    JUNK BONDS. A Portfolio's investments in securities rated
                    lower than investment grade or if unrated of comparable
                    quality as determined by the Investment Manager or
                    Sub-Advisor (commonly known as "junk bonds") pose
                    significant risks. The prices of junk bonds are likely to be
                    more sensitive to adverse economic changes or individual
                    corporate developments than higher rated securities. During
                    an economic downturn or substantial period of rising
                    interest rates, junk bond issuers and, in particular, highly
                    leveraged issuers may experience financial stress that would
                    adversely affect their ability to service their principal
                    and interest payment obligations, to meet their projected
                    business goals or to obtain additional financing. In the
                    event of a default, the Portfolio may incur additional
                    expenses to seek recovery. The secondary market for junk
                    bonds 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 Rule 144A
                    securities could have the effect of increasing the level of
                    Portfolio illiquidity to the extent a Portfolio may be
                    unable to find qualified institutional buyers interested in
                    purchasing the 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 junk bonds at certain
                    times and could make it difficult for the Portfolios to sell
                    certain securities. In addition, periods of economic
                    uncertainty and change probably would result in an increased
                    volatility of market prices of high yield securities and a
                    corresponding volatility in a Portfolio's net asset value.

                    SECURITIES RATED IN THE LOWEST INVESTMENT GRADE
                    CATEGORY. Investments in the fixed-income securities rated
                    in the lowest investment grade category by Moody's or S&P
                    may have speculative characteristics and therefore changes
                    in economic 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.

                    FOREIGN SECURITIES. Foreign securities involve risks in
                    addition to the risks associated with domestic securities.
                    One additional risk is currency risk. While the price of
                    Portfolio shares is quoted in U.S. dollars, a Portfolio
                    generally converts U.S. dollars to a foreign market's local
                    currency to purchase a security in that market. If the value
                    of that local currency falls relative to the U.S. dollar,
                    the U.S. dollar value of the foreign security will decrease.
                    This is true even if the foreign security's local price
                    remains unchanged.

                    Foreign securities (including depository receipts) also have
                    risks related to economic and political developments abroad,
                    including effects of foreign social, economic or political
                    instability. Foreign companies, in general, are not subject
                    to the regulatory requirements of U.S. companies and, as
                    such, there may be less publicly available information about
                    these companies. Moreover, foreign accounting, auditing and
                    financial reporting standards generally are different from
                    those applicable to U.S. companies. Finally, in the event of
                    a default of any foreign debt obligations, it may be more
                    difficult for the Fund to obtain or enforce a judgment
                    against the issuers of the securities.

                    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
                    U.S. counterparts.

                    The foreign securities in which certain of the Portfolios
                    may invest (in particular the Pacific Growth Portfolio) may
                    be issued by companies 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 that trade a small number of securities.
                    Prices of these securities tend to be especially volatile
                    and, in the past, securities in these countries have offered
                    greater potential loss (as well as gain) than securities of
                    companies located in developed countries.

                    SMALL & MEDIUM CAPITALIZATION COMPANIES. A Portfolio's
                    investments in smaller and medium sized companies carry more
                    risk than investments in larger companies. While some of a
                    Portfolio's holdings in these companies may be listed on a
                    national securities exchange, such securities are more
                    likely to be traded in the over-the-counter market. The low
                    market liquidity of these securities may have an adverse
                    impact on a Portfolio's ability to sell certain securities
                    at favorable prices and may also make it difficult for a
                    Portfolio to obtain market quotations based on actual
                    trades, for purposes of valuing a Portfolio's securities.
                    Investing in lesser-known, smaller and medium capitalization
                    companies involves greater risk of volatility of a
                    Portfolio's net asset value than is customarily associated
                    with larger, more established companies. Often smaller and
                    medium capitalization companies and the industries in which
                    they are focused are still evolving and, while this may
                    offer better growth potential than larger, more established
                    companies, it also may make them more sensitive to changing
                    market conditions.

                    OPTIONS AND FUTURES. If a Portfolio invests in options
                    and/or futures, its participation in these markets would
                    subject the Portfolio to certain risks. The Investment
                    Manager's or the Sub-Advisor's predictions of movements in
                    the direction of the stock, bond, currency or interest rate
                    markets may be inaccurate, and the adverse consequences to
                    the Portfolio (e.g., a reduction in the Portfolio's net
                    asset value or a reduction in the amount of income available
                    for distribution) may leave the Portfolio in a worse
                    position than if these strategies were not used. Other risks
                    inherent in the use of options and futures include, for
                    example, the possible imperfect correlation between the
                    price of options and futures contracts and movements in the
                    prices of the securities being hedged, and the possible
                    absence of

                                                                              49
<PAGE>
                    a liquid secondary market for any particular instrument.
                    Certain options may be over-the-counter options, which are
                    options negotiated with dealers; there is no secondary
                    market for these investments.

                    FORWARD CURRENCY CONTRACTS. A Portfolio's participation in
                    forward currency contracts also involves risks. If the
                    Investment Manager or Sub-Advisor employs a strategy that
                    does not correlate well with the Portfolio's investments or
                    the currencies in which the investments are denominated,
                    currency contracts could result in a loss. The contracts
                    also may increase the Portfolio's volatility and may involve
                    a significant risk.

                    REAL ESTATE INVESTMENT TRUSTS ("REITS"). REITs pool
                    investors funds for investments primarily in commercial real
                    estate properties. Like mutual funds, REITs have expenses,
                    including advisory and administration fees that are paid by
                    its shareholders. As a result, you will absorb duplicate
                    levels of fees when a Portfolio invests in REITs. The
                    performance of any Portfolio REIT holdings ultimately
                    depends on the types of real property in which the REITs
                    invest and how well the property is managed. A general
                    downturn in real estate values also can hurt REIT
                    performance.

PORTFOLIO MANAGEMENT

                    Morgan Stanley Dean Witter Advisors Inc. is the Investment
                    Manager to each Portfolio. Each Portfolio has retained the
                    Investment Manager to provide administrative services,
                    manage its business affairs and (except for the Pacific
                    Growth and European Growth Portfolios) invest its assets,
                    including the placing of orders for the purchase and sale of
                    portfolio securities. The Investment Manager is a wholly-
                    owned subsidiary of Morgan Stanley Dean Witter & Co., a
                    preeminent global financial services firm that maintains
                    leading market positions in each of its three primary
                    businesses: securities, asset management and credit
                    services. Its main business office is located at Two World
                    Trade Center, New York, NY 10048.

                    Each of the Pacific Growth and European Growth Portfolios
                    has retained the Investment Manager to supervise the
                    investment of its assets. The Investment Manager has, in
                    turn, contracted with the Sub-Advisor - Morgan Stanley Dean
                    Witter Investment Management Inc. - to invest each
                    Portfolio's assets, including the placing of orders for the
                    purchase and sale of portfolio securities. The Sub-Advisor
                    also is a subsidiary of Morgan Stanley Dean Witter & Co. Its
                    main business office is located at 1221 Avenue of the
                    Americas, New York, NY 10020.


                    Each Portfolio pays the Investment Manager a monthly
                    management fee as full compensation for the services and
                    facilities furnished to each Portfolio, and for Portfolio
                    expenses assumed by the Investment Manager. The fee is based
                    on the Portfolio's average daily net assets. For the fiscal
                    year ended December 31, 1999, each Portfolio accrued total
                    compensation to the Investment Manager as set forth in the
                    following table.

SHAREHOLDER INFORMATION

[ICON]              PRICING FUND SHARES
--------------------------------------------------------------------------------
                    The price of shares of each Portfolio called "net asset
                    value," is based on the value of its portfolio securities.

                    The net asset value for each Portfolio is calculated once
                    daily at 4:00 p.m. Eastern time on each day the New York
                    Stock Exchange is open (or, on days when the New York Stock
                    Exchange closes prior to 4:00 p.m., at such earlier time).
                    Shares will not be priced on days that the New York Stock
                    Exchange is closed.

                    The value of each Portfolio's securities (other than the
                    Money Market Portfolio) is based on the securities' market
                    price when available. When a market price is not readily
                    available, including circumstances under which the
                    Investment Manager (or, if applicable, the Sub-Advisor)
                    determines that a security's market price is not accurate, a
                    portfolio security is valued at its fair value, as
                    determined under procedures established by the Fund's Board
                    of Trustees. In these cases, the applicable Portfolio's net
                    asset value will reflect certain portfolio securities' fair
                    value rather than their market price. In addition, with
                    respect to securities that are primarily listed on foreign
                    exchanges, the value of the Portfolio's investment
                    securities may change on days when shareholders will not be
                    able to purchase or sell their shares.

                    An exception to the general policy of using market prices
                    concerns each Portfolio's short-term debt portfolio
                    securities. Debt securities with remaining maturities of
                    sixty days or less at the time of purchase are valued at
                    amortized cost. However, if the cost does not reflect the
                    securities' market value, these securities will be valued at
                    their fair value.

                    The Money Market Portfolio utilizes amortized cost in
                    determining the value of its portfolio securities. The
                    amortized cost valuation method involves valuing a debt
                    obligation in reference to its acquisition cost rather than
                    market forces.

[ICON]              DISTRIBUTIONS
--------------------------------------------------------------------------------
                    Each Portfolio passes substantially all of its earnings from
                    income and capital gains along to its investors as
                    "distributions." Each Portfolio earns income from stocks
                    and/or interest from fixed-income investments. These amounts
                    are passed along to the appropriate Portfolio investors as
                    "income dividend distributions." Each Portfolio realizes
                    capital gains whenever it sells securities for a higher
                    price than it paid for them. These amounts may be passed
                    along as "capital gain distributions."

                    Dividends from net investment income and capital gains
                    distributions, if any, are declared and paid as follows:

FINANCIAL HIGHLIGHTS

          The financial highlights table is intended to help you understand the
          financial performance of each Portfolio's Class X shares for the past
          5 fiscal years of the Fund. Prior to May 1, 2000, the Fund issued one
          Class of shares of each Portfolio, which, as of that date, have been
          designated Class X shares. Certain information reflects financial
          results for a single Portfolio share. The total returns in the tables
          represent the rate an investor would have earned or lost on an
          investment in each Portfolio (assuming reinvestment of all dividends
          and distributions).


          The information for each of the periods through December 31, 1999 has
          been audited by PricewaterhouseCoopers LLP, independent accountants,
          whose report, along with the Fund's financial statements, is included
          in the annual report, which is available upon request. The information
          for the six-month period ended June 30, 2000 is unaudited.

Further information about the performance of the Portfolios of the Fund is
contained in the annual report. 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 issued by the applicable
insurance company for a description of charges which are applicable thereto.
These charges are not reflected in the financial highlights below. Inclusion of
any of these charges would reduce the total return figures for all periods
shown. The financial highlights table does not cover the Information Portfolio,
which had not commenced operations prior to the date of this PROSPECTUS.

THE PORTFOLIOS

THE MONEY MARKET PORTFOLIO

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The Money Market Portfolio seeks high current income,
                    preservation of capital and liquidity.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio invests in high quality, short-term debt
                    obligations. In selecting investments, the "Investment
                    Manager," Morgan Stanley Dean Witter Advisors Inc., seeks to
                    maintain the Portfolio's share price at $1.00. A mutual
                    fund's share price remaining stable at $1.00 means that the
                    fund would preserve the principal value of the shareholders'
                    investments.

                    The Portfolio's investments are limited, as a matter of
                    fundamental investment policy, which may not be changed
                    without shareholder approval, to the following types of
                    money market instruments:

                    fluctuate based upon changes in market rates.

                    The Portfolio attempts to balance its objectives of high
                    income, capital preservation and liquidity by investing in
                    securities of varying maturities and risks. The Portfolio
                    does not, however, invest in securities that mature in more
                    than one year from the date of purchase.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objectives.

                    Principal risks of investing in the Portfolio are associated
                    with its debt obligation investments. All debt obligations,
                    such as bonds, are subject to two types of risk: credit risk
                    and interest rate risk. Credit risk refers to the
                    possibility that the issuer of a security will be unable to
                    make interest payments and/or repay the principal on its
                    debt. Interest rate risk refers to fluctuations in the value
                    of a debt security resulting from changes in the general
                    level of interest rates.

                    The Investment Manager actively manages the Portfolio's
                    assets to reduce the risk of losing any principal investment
                    as a result of credit or interest rate risks. The
                    Portfolio's assets are reviewed to maintain or improve
                    creditworthiness. In addition, federal regulations require
                    money market funds to invest only in debt obligations of
                    high quality and short maturities, and repurchase agreements
                    with respect to such obligations.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy.

                    An investment in the Portfolio is not a bank deposit and is
                    not guaranteed or insured by the FDIC or any other
                    government agency. Although the Portfolio seeks to preserve
                    the value of your investment at $1.00 per share, if it is
                    unable to do so, it is possible to lose money by investing
                    in the Portfolio.

                                                                               3

THE SHORT-TERM BOND PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Short-Term Bond Portfolio seeks to provide a high level
                    of current income consistent with the preservation of
                    capital.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in bonds issued or guaranteed as to principal and
                    interest by the U.S. Government, its agencies or
                    instrumentalities (including zero coupon securities), and
                    investment grade corporate and other types of bonds. In
                    selecting portfolio investments, the "Investment Manager,"
                    Morgan Stanley Dean Witter Advisors Inc., considers both
                    domestic and international economic developments, interest
                    rate trends and other factors and seeks to maintain an
                    overall weighted average maturity for the Portfolio of less
                    than three years.

                    MORTGAGE-BACKED SECURITIES. Certain of the U.S. Government
                    securities in which the Portfolio may invest are
                    mortgage-backed securities. One type of mortgage-backed
                    security, in which the Portfolio may invest, is a mortgage
                    pass-through security. These securities represent a
                    participation interest in a pool of residential mortgage
                    loans originated by U.S. Governmental or private lenders
                    such as banks. They differ from conventional debt
                    securities, which provide for periodic payment of interest
                    in fixed amounts and principal payments at maturity or on
                    specified call dates. Mortgage pass-through securities
                    provide for monthly payments that are a "pass-through" of
                    the monthly interest and principal payments made by the
                    individual borrowers on the pooled mortgage loans. Mortgage
                    pass-through securities may be collateralized by mortgages
                    with fixed rates of interest or adjustable rates.

                    In addition, the Portfolio may invest up to 25% of its
                    assets in investment grade fixed-income securities issued by
                    foreign governments or corporations. The Portfolio's
                    investments also may include "Rule 144A" fixed-income
                    securities, which are subject to resale restrictions. Up to
                    5% of the Portfolio's assets may be invested in fixed-income
                    securities rated lower than investment grade, or if unrated
                    of comparable quality as determined by the Investment
                    Manager (commonly known as "junk bonds").

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------

                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price and yield
                    will fluctuate with changes in the market value of its
                    portfolio securities. When you sell Portfolio shares, they
                    may be worth less than what you paid for them and,
                    accordingly, you can lose money investing in this Portfolio.


                    Principal risks of investing in the Portfolio are associated
                    with the Portfolio's investments in fixed-income securities.
                    These risks are credit risk and interest rate risk. Credit
                    risk is the possibility that the issuer of a security will
                    be unable to make interest payments and/or repay the
                    principal on its debt. Interest rate risk refers to
                    fluctuations in the value of a fixed-income security
                    resulting from changes in the general level of interest
                    rates.

                                                                               5
<PAGE>
                    There are also particular risks associated with the
                    Portfolio's investments in mortgage-backed securities. For
                    example mortgage-backed securities are subject to prepayment
                    risk and in some cases may be more volatile and less liquid
                    than other traditional types of debt securities.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.


                    The Portfolio commenced operations on May 3, 1999 and prior
                    to the date of this PROSPECTUS did not have a full calendar
                    year of performance to report.

THE QUALITY INCOME PLUS PORTFOLIO

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The Quality Income Plus Portfolio seeks as a primary
                    objective to provide a high level of current income by
                    investing primarily in U.S. government securities and other
                    fixed-income securities. As a secondary objective the
                    Portfolio seeks capital appreciation but only when
                    consistent with its primary objective.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in (i) U.S. Government securities issued or
                    guaranteed as to principal and interest by the U.S.
                    Government, its agencies or instrumentalities, (ii) debt
                    securities (including zero coupon securities), rated at the
                    time of purchase within the three highest bond rating
                    categories by Moody's or S&P or if not rated determined to
                    be of comparable quality by the "Investment Manager," Morgan
                    Stanley Dean Witter Advisors Inc., and (iii) Yankee
                    government bonds rated at the time of purchase within the
                    three highest rating categories of Moody's or S&P or if not
                    rated determined to be of comparable quality by the
                    Investment Manager. Yankee government bonds are U.S. dollar
                    denominated bonds issued by foreign government agencies or
                    instrumentalities (no more than 20% of the Portfolio's
                    assets may be invested in Yankee government bonds). The
                    Portfolio is not limited as to the maturities of the U.S.
                    Government and other debt securities in which it may invest.

                    In making investment decisions for the Portfolio, the
                    Investment Manager considers both domestic and international
                    economic developments, interest rate trends and other
                    factors. The Investment Manager evaluates technical
                    considerations such as the relative supply of and demand for
                    corporate notes and U.S. Treasury and agencies issues before
                    it decides upon an asset allocation. Similarly, the
                    assessment of the strength of individual companies that
                    issue corporate debt and the overall country risk of
                    sovereign debt obligations contribute to the decision-making
                    process.

                    MORTGAGE-BACKED SECURITIES. Certain of the U.S. Government
                    securities in which the Portfolio may invest are
                    mortgage-backed securities. One type of mortgage-backed
                    security, in which the Portfolio may invest, is a mortgage
                    pass-through security. These securities represent a
                    participation interest in a pool of residential mortgage
                    loans originated by U.S. Governmental or private lenders
                    such as banks. They differ from conventional debt
                    securities, which provide for periodic payment of interest
                    in fixed amounts and principal payments at maturity or on
                    specified call dates. Mortgage pass-through securities
                    provide for monthly payments that are a "pass-through" of
                    the monthly interest and principal payments made by the
                    individual borrowers on the pooled mortgage loans. Mortgage
                    pass-through securities may be collateralized by mortgages
                    with fixed rates of interest or adjustable rates.

                                                                               7

                    BORROWING. In seeking to increase income, the Portfolio may
                    borrow to purchase securities. Such borrowing may not exceed
                    25% of the Portfolio's total assets.

                    OTHER INVESTMENTS. The Portfolio may invest up to 15% of its
                    assets in Yankee corporate bonds which are rated at the time
                    of purchase within the three highest grades as determined by
                    Moody's or S&P or which, if not rated, are of comparable
                    quality as determined by the Investment Manager. Yankee
                    corporate bonds are U.S. dollar denominated debt securities
                    issued by foreign companies.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------

                    There is no assurance that the Portfolio will achieve its
                    investment objectives. The Portfolio's share price and yield
                    will fluctuate with changes in the market value of its
                    portfolio securities. When you sell Portfolio shares, they
                    may be worth less than what you paid for them and,
                    accordingly, you can lose money investing in this Portfolio.


                    A principal risk of investing in the Portfolio is associated
                    with the Portfolio's investments in fixed-income securities.
                    These risks are credit risk and interest rate risk. Credit
                    risk is the possibility that the issuer of a security will
                    be unable to make interest payments and/or repay the
                    principal on its debt. Interest rate risk refers to
                    fluctuations in the value of a fixed-income security
                    resulting from changes in the general level of interest
                    rates.

                    There are also particular risks associated with the
                    Portfolio's investments in mortgage-backed securities. For
                    example mortgage-backed securities are subject to prepayment
                    risk and in some cases may be more volatile and less liquid
                    than other traditional types of debt securities.

                    The Portfolio may borrow money to purchase securities. To
                    the extent that the Portfolio engages in such practice it
                    may be leveraged. Leveraging generally exaggerates the
                    effect on net asset value of any increase or decrease in the
                    market value of the Portfolio's investments.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see

THE HIGH YIELD PORTFOLIO

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The High Yield Portfolio seeks as a primary objective to
                    provide a high level of current income by investing in a
                    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 Portfolio will seek capital
                    appreciation, but only when consistent with its primary
                    objective.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in fixed-income securities (including zero coupon
                    securities) rated Baa or lower by Moody's or BBB or lower by
                    S&P or in nonrated securities considered by the Investment
                    Manager to be appropriate investments for the Portfolio.
                    These securities are commonly known as "junk bonds." They
                    may also include "Rule 144A" securities, which are subject
                    to resale restrictions. There are no minimum quality ratings
                    for investments.

                    In making investment decisions the "Investment Manager,"
                    Morgan Stanley Dean Witter Advisors Inc., considers an
                    issuer's creditworthiness, economic developments, interest
                    rate trends and other factors it deems relevant. In
                    evaluating an issuer's creditworthiness the Investment
                    Manager relies principally on its own analysis. A security's
                    credit rating is simply one factor that may be considered by
                    the Investment Manager in this regard.

                    In addition to junk bonds, the Portfolio may invest in the
                    following:

                    - Higher rated fixed-income securities -- The Portfolio may
                      invest in securities rated higher than Baa or BBB (or if
                      not rated, determined to be of comparable quality) when
                      the Investment Manager believes that such securities may
                      produce attractive yields.

                    - Foreign securities -- The Portfolio may invest up to 20%
                      of its assets in securities issued by foreign governments
                      and other foreign issuers (including American depository
                      receipts or other similar securities convertible into
                      securities of foreign issuers) but not more than 10% of
                      its assets in these securities may be denominated in
                      foreign currencies.

                    - Unit Offerings -- The Portfolio may purchase units which
                      combine debt securities with equity securities and/or
                      warrants.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------

                    There is no assurance that the Portfolio will achieve its
                    investment objectives. The Portfolio's share price and yield
                    will fluctuate with changes in the market value of its
                    portfolio securities. When you sell Portfolio shares, they
                    may be worth less than what you paid for them and,
                    accordingly, you can lose money investing in this Portfolio.


                    A principal risk of investing in the Portfolio is associated
                    with its investments in junk bonds. Junk bonds are subject
                    to greater risk of loss of income and principal than higher
                    rated securities. The prices of junk bonds have been found
                    generally to be less sensitive to changes in prevailing
                    interest rates than higher rated securities

                    but are more likely to be sensitive to adverse economic
                    changes or individual corporate developments. In addition,
                    all fixed-income securities are subject to two types of
                    risk: credit risk and interest rate risk.

                    The Portfolio is subject to the risks associated with
                    foreign securities. These risks include, among other things,
                    the possibility that the Portfolio could be adversely
                    affected by changes in currency exchange rates.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see

[End Sidebar]

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Utilities Portfolio seeks both capital appreciation and
                    current income.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------

                    The Portfolio will normally invest at least 65% of its total
                    assets in the securities of companies engaged in the
                    utilities industry. These companies are involved in various
                    aspects of the industry, such as communications, and gas and
                    electric energy, but they do not include public broadcasting
                    companies. A company will be considered engaged in the
                    utilities industry if it derives at least 50% of its
                    revenues or earnings from that industry or it devotes at
                    least 50% of its assets to activities in that industry.
                    These may include companies involved in, among other things,
                    telecommunications, computers and other new or emerging
                    technologies, gas and electric energy, water distribution,
                    the Internet and Internet related services. The companies
                    may be traditionally regulated public utilities or fully or
                    partially deregulated utility companies as well as
                    unregulated utility companies.

                    The Portfolio's "Investment Manager," Morgan Stanley Dean
                    Witter Advisors Inc., will shift the Portfolio's assets
                    between different segments of the utilities industry and
                    between common stock, other equity securities and investment
                    grade fixed-income securities based on its view of
                    prevailing market, economic and financial conditions. The
                    Portfolio does not have any set policies to concentrate its
                    assets in any particular segment of the utilities industry
                    or any particular type of security. However, the Portfolio's
                    policy to concentrate its assets in the utilities industry
                    is fundamental, and may not be changed without shareholder
                    approval. In selecting common stock and other equity
                    securities, the Investment Manager considers 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.
                    Computer-based equity selection models also may be used. If
                    the Investment Manager believes favorable conditions for
                    capital growth of equity securities are not prevalent at a
                    particular time, it may allocate the Portfolio's assets
                    predominantly or exclusively to debt securities with the aim
                    of obtaining current income and thus benefitting long-term

                    limitation, however, does not apply to securities of foreign

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    The Portfolio invests primarily in securities of companies
                    in the utilities industry. The Portfolio's investments in
                    the utilities industry are impacted by a host of risks
                    particular to that industry. Changing regulation constitutes
                    one of the key industry-specific risks for the Portfolio.
                    State and other regulators monitor and control utility
                    revenues and costs, and therefore may limit utility profits
                    and dividends paid to investors. Regulatory authorities also
                    may restrict a company's access to new markets, thereby
                    diminishing the company's long-term prospects. Individual
                    sectors of the utility market are subject to additional
                    risks. These risks apply to all utility companies --
                    regulated, fully or partially deregulated and unregulated.
                    For example, telecommunications companies have been affected
                    by technological development leading to increased
                    competition, as well as changing regulation of local and
                    long-distance telephone service and other telecommunications
                    businesses. Certain telecommunications companies have not
                    benefitted from the new competitive climate.

                    Electric utilities may incur unexpected increases in fuel
                    and other operating costs. They are adversely affected when
                    long-term interest rates rise. Long-term borrowings are used
                    to finance most utility investment and rising interest rates
                    lead to higher financing costs and reduced earnings. There
                    are also the considerable costs associated with
                    environmental compliance, nuclear waste clean-up, and safety
                    regulation. Increasingly, regulators are calling upon
                    electric utilities to bear these added costs, and there is a
                    risk that these costs will not be fully recovered through an
                    increase in revenues.

                    Among gas companies, there has been a move to diversify into
                    oil and gas exploration and development, making investment
                    return more sensitive to energy prices. In the case of the
                    water utility sector, the industry is highly fragmented, and
                    most water supply companies find themselves in mature
                    markets, although upgrading of fresh water and waste water
                    systems is an expanding business.

                    The Portfolio's investments in common stock are also subject
                    to the risks that affect all common stocks. In particular,
                    stock prices can fluctuate widely in response to activities
                    specific to the issuer as well as general market economic
                    and political conditions.

                    The Portfolio's investment in fixed-income securities are
                    subject to credit risk and interest rate risk. Credit risk
                    refers to a possibility that the issuer of a security will
                    be unable to make interest payments and/or repay the
                    principal on its debts. Interest rate risk refers to
                    fluctuations in the value of a fixed-income security
                    resulting from changes in the general level of interest
                    rates.

                    The Portfolio is subject to the risks associated with
                    foreign securities. These risks include, among other things,
                    the possibility that the Portfolio could be adversely
                    affected by changes in currency exchange rates.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.

THE INCOME BUILDER PORTFOLIO

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The Income Builder Portfolio seeks as a primary objective
                    reasonable income. Growth of capital is the secondary
                    objective.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in income-producing equity securities, including
                    common stock, preferred stock and convertible securities.
                    The "Investment Manager," Morgan Stanley Dean Witter
                    Advisors Inc., uses a value-oriented style in the selection
                    of securities. Investments are normally made primarily in
                    (i) common stocks of large capitalization companies with a
                    record of paying dividends and which in the opinion of the
                    Investment Manager have the potential for maintaining
                    dividends, (ii) preferred stock and (iii) securities
                    convertible into common stocks of small and midcap
                    companies -- including synthetic and enhanced convertibles.
                    The Portfolio's investments may also include "Rule 144A"
                    securities, which are subject to resale restrictions.

                    The Investment Manager follows a "bottom-up" approach in the
                    selection of convertible securities for the Portfolio.
                    Beginning with a universe of about 500 companies, the
                    Investment Manager narrows the focus to small and midcap
                    companies and reviews the issues to determine if the
                    convertible is trading with the underlying equity security.
                    The yield of the underlying equity security is evaluated and
                    company fundamentals are studied to evaluate cash flow,
                    risk/reward balance, valuation and the prospects for growth.

                    The Portfolio may invest up to 25% of its assets in
                    "enhanced" convertible securities. Enhanced convertible
                    securities offer holders the opportunity to obtain higher
                    current income than would be available from a traditional
                    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.

                    The Portfolio may invest up to 10% of its 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.

<PAGE>
                    The Portfolio may invest up to 20% of its assets in
                    fixed-income securities rated lower than investment grade by
                    S&P or Moody's (but not below B) or if unrated of comparable
                    quality as determined by the Investment Manager (commonly
                    known as "junk bonds"). The 20% limitation is not applicable
                    to convertible securities.

                    The Portfolio may invest up to 35% of its assets in U.S.
                    Government securities issued or guaranteed as to principal
                    and interest by the U.S. Government or its agencies or
                    instrumentalities and investment grade fixed-income
                    securities (including zero coupon securities), common stocks
                    that do not pay a regular dividend and real estate
                    investment trusts (commonly known as "REITs").

                    The Portfolio may invest up to 25% of its assets in foreign
                    securities (including depository receipts). This percentage
                    limitation, however, does not apply to securities of foreign
                    companies that are listed in the U.S. on a national
                    securities exchange.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objectives. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investing in the Portfolio is associated
                    with its investment in common stocks. In particular the
                    prices of common stocks can fluctuate widely in response to
                    activities specific to the issuer as well as general market,
                    economic and political conditions.

                    The Portfolio is also subject to the risks of investing in
                    convertible securities. These securities may carry risks
                    associated with both common stock and fixed-income
                    securities. In addition, because the convertible securities
                    in which the Portfolio invests are convertible into the
                    common stocks of small and midcap companies, the Portfolio
                    is subject to the specific risks associated with investing
                    in small and midcap companies. Investments in small and
                    medium capitalization companies involve greater risk of
                    volatility than is customarily associated with investments
                    in more established companies as well as certain other
                    additional risks.

                    There are also special risks associated with the Portfolio's
                    investments in "enhanced" and "synthetic" convertible
                    securities. These securities may be more volatile and less
                    liquid than traditional convertible securities.

                    The Portfolio is subject to the risks associated with
                    foreign securities. These risks include, among other things,
                    the possibility that the Portfolio could be adversely
                    affected by changes in currency exchange rates.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.

THE DIVIDEND GROWTH PORTFOLIO

[SIDEBAR]
GROWTH & INCOME
An investment objective having the goal of selecting securities with the

[End Sidebar]

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The Dividend Growth Portfolio seeks to provide reasonable
                    current income and long term growth of income and capital.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will invest at least 70% of its total assets
                    in common stock of companies with a record of paying
                    dividends and the potential for increasing dividends. The
                    "Investment Manager," Morgan Stanley Dean Witter Advisors
                    Inc., initially employs a quantitative screening process in
                    an attempt to develop a number of common stocks which are
                    undervalued and which have a record of paying dividends. The
                    Investment Manager then applies qualitative analysis to
                    determine which stocks it believes have the potential to
                    increase dividends and, finally, to determine whether any of
                    the stocks should be added to the Portfolio. The Investment
                    Manager attempts to avoid investment in speculative
                    securities or those with speculative characteristics.

                    The Portfolio may invest up to 30% of its assets in
                    convertible securities, U.S. Government securities issued or
                    guaranteed as to principal and interest by the U.S.
                    Government, its agencies or instrumentalities, and
                    investment grade fixed-income securities (including zero
                    coupon securities). The Portfolio may also invest any amount
                    of its assets in foreign securities (including depository
                    receipts) that are listed in the U.S. on a national
                    securities exchange.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objectives. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investing in the Portfolio is associated
                    with its investments in common stock. In particular the
                    prices of common stock may fluctuate widely in response to
                    activities specific to the company as well as general
                    market, economic and political conditions.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.

THE CAPITAL GROWTH PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Capital Growth Portfolio seeks long term capital growth.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in common stocks. The "Investment Manager," Morgan
                    Stanley Dean Witter Advisors Inc., utilizes a two-stage
                    computerized screening process designed to find companies
                    that demonstrate a history of consistent growth in earnings
                    and revenues over the past several years, and have solid
                    future earnings growth characteristics and attractive
                    valuations. Dividend income is not a consideration in this
                    stock selection process. Companies meeting these
                    requirements are potential candidates for investment by the
                    Portfolio. The Investment Manager may modify the screening
                    process and/or may utilize additional or different screening
                    processes in connection with the Portfolio's investments.

                    The Portfolio may invest up to 35% of its assets in U.S.
                    Government securities issued or guaranteed as to principal
                    and interest by the U.S. Government or its agencies or
                    instrumentalities, investment grade fixed-income securities
                    (including zero coupon securities), convertible securities,
                    unit offerings involving a combination of a debt security
                    and a convertible security and/or warrant and real estate
                    investment trusts (commonly known as "REITs").

                    The Portfolio may invest up to 25% of its assets in foreign
                    securities (including depository receipts). This percentage
                    limitation, however, does not apply to securities of foreign
                    companies that are listed in the U.S. on a national
                    securities exchange.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common stock.
                    In particular the prices of common stocks may fluctuate
                    widely in response to activities specific to the company as
                    well as general market, economic and political conditions.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed

                    The bar chart and table below provide some indication of the
                    risks of investing in the Capital Growth Portfolio. The
                    Portfolio's past performance does not indicate how it will
                    perform in the future. The returns shown do not reflect fees
                    charged under the life insurance or annuity contracts, which
                    would lower the performance for all periods shown.

THE GLOBAL DIVIDEND GROWTH PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Global Dividend Growth Portfolio seeks to provide
                    reasonable current income and long term growth of income and
                    capital.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in dividend paying equity securities issued by
                    issuers located in various countries around the world. The
                    "Investment Manager," Morgan Stanley Dean Witter Advisors
                    Inc., seeks investments primarily in common stock of
                    companies with a record of paying dividends and potential
                    for increasing dividends. The Portfolio invests in at least
                    three separate countries. The percentage of 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 Portfolio's assets may be invested as
                    follows:

                    - Convertible securities, U.S. Government securities issued
                      or guaranteed as to principal and interest by the U.S.
                      Government, its agencies or instrumentalities,
                      fixed-income securities issued by foreign governments and
                      international organizations and investment grade debt
                      securities (including zero coupon securities).

                    - Forward currency contracts, which involve the purchase or
                      sale of a specific amount of foreign currency at a
                      specified price with delivery at a specified future date.
                      The Portfolio may use these contracts to hedge against
                      adverse price movements in its portfolio securities and
                      the currencies in which they are denominated.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of Investment in the Portfolio is
                    associated with the Portfolio's investments in common
                    stocks. In particular, the price of common stocks may
                    fluctuate widely in response to activities specific to the
                    company as well as general market, economic and political
                    conditions.

                    Another principal risk relates to the Portfolio's
                    investments in foreign securities. In particular, foreign
                    security investments may be adversely affected by changes in
                    currency exchange rates. In addition, investments in foreign
                    securities may be adversely affected by among other things
                    political, social and economic developments abroad.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see

THE EUROPEAN GROWTH PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The European Growth Portfolio seeks to maximize the capital
                    appreciation of its investments.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in securities issued by issuers located in European
                    countries. A company is considered located in Europe if
                    (i) it is organized under the laws of a European country and
                    has a principal office in a European country; (ii) it
                    derives at least 50% of its total revenue from business in
                    Europe; or (iii) the company's equity securities are traded
                    principally on a stock exchange in Europe. The principal
                    countries in which the Portfolio invests are France, the
                    United Kingdom, Germany, the Netherlands, Spain, Sweden,
                    Switzerland and Italy. The Portfolio invests in at least
                    three separate countries.

                    The Portfolio generally invests principally in equity
                    securities (which may include depository receipts or
                    convertible securities) but may also invest without
                    limitation in fixed-income securities issued or guaranteed
                    by European governments when the "Investment Manager,"
                    Morgan Stanley Dean Witter Advisors Inc., or the "Sub-
                    Advisor," Morgan Stanley Dean Witter Investment Management
                    Inc., determine such investments to be appropriate.

                    The Investment Manager and the Sub-Advisor generally invest
                    Portfolio assets in companies they believe have a high rate
                    of earnings growth potential. They also select securities,
                    which in their view, possess, both on an absolute basis and
                    as compared with other securities around the world,
                    attractive price/earnings, price/ cash flow and
                    price/revenue ratios.

                    The Portfolio may invest up to 35% of its assets as follows:

                    - Equity securities issued by non-European issuers, and
                      government and convertible securities issued by
                      non-European governmental or private issuers.

                    - Forward currency contracts, which involve the purchase or
                      sale of a specific amount of foreign currency at the
                      current price with delivery at a specified future date.
                      The Portfolio may use these contracts to hedge against
                      adverse price movements in its portfolio securities and
                      securities it intends to purchase and the currencies in
                      which they are denominated.


                    The Portfolio may invest up to 5% of its assets in put and
                    call options with respect to foreign currencies. The
                    Portfolio may also purchase and sell stock index futures
                    contracts and options thereon. Stock index futures and
                    options thereon may be used to facilitate trading, to
                    increase the Portfolio's market exposure or to seek to
                    protect against an increase in the prices of securities that
                    may be purchased.


                    The Portfolio may invest in warrants and acquire warrants
                    attached to other securities.

                                                                              25

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk factor associated with investment in the
                    Portfolio relates to the Portfolio's investments in Europe.
                    In particular, adverse political, social or economic
                    developments in Europe, or in a particular European country,
                    could cause a substantial decline in the value of the
                    Portfolio.

                    The Portfolio's investments in common stock are also subject
                    to the risks that affect all common stocks. In particular,
                    stock prices can fluctuate widely in response to activities
                    specific to the issuer as well as general market economic
                    and political conditions.

                    The conversion to a single European currency by many
                    European countries could potentially adversely affect the
                    value and/or increase the volatility of the Portfolio's
                    investments.

                    In addition, the Portfolio is subject to the risks
                    associated with foreign securities generally. These risks
                    include, among other things, the possibility that the
                    Portfolio could be adversely affected by changes in currency
                    exchange rates.

                    In addition, the Portfolio's investments in fixed-income
                    securities are subject to two types of risk: credit risk and
                    interest rate risk.

                    The Portfolio is also subject to the risks of investing in
                    convertible securities. These securities may carry risks
                    associated with both common and fixed-income securities.

                    The performance of the Portfolio also will depend on whether
                    the Sub-Advisor is successful in pursuing the Portfolio's
                    investment strategy. In addition, the Portfolio is subject
                    to other risks from its permissible investments. For
                    information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.

                       Portfolio (which are offered in a separate prospectus).
                       Class X and Class Y shares are invested in the same
                       portfolio of securities. However, the returns for
                       Class Y shares would differ from those of Class X to the
                       extent the Classes have different expenses.

THE PACIFIC GROWTH PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Pacific Growth Portfolio seeks to maximize the capital
                    appreciation of its investments.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in common stocks (including depository receipts) and
                    other securities of companies which are (i) organized under
                    the laws of and have a principal place of business in Asia,
                    Australia or New Zealand or (ii) derives at least 50% of
                    their total revenues from business in such areas. The
                    principal Asian countries include: Japan, Malaysia,
                    Singapore, Hong Kong, Thailand, the Philippines, India,
                    Indonesia, Taiwan and South Korea. The Portfolio's assets
                    are invested in at least three countries. The Portfolio may
                    invest more than 25% of its assets in Japan, Hong Kong,
                    South Korea and Taiwan. Thus, the investment performance of
                    the Portfolio may be subject to the social, political and
                    economic events occurring in these countries to a greater
                    extent than other countries.

                    The "Investment Manager," Morgan Stanley Dean Witter
                    Advisors Inc., and the "Sub-Advisor," Morgan Stanley Dean
                    Witter Investment Management Inc., generally invest
                    Portfolio assets in companies they believe have a high rate
                    of earnings growth potential. They also select securities,
                    which in their view, possess, both on an absolute basis and
                    as compared with other securities around the world,
                    attractive price/earnings, price/cash flow and price/revenue
                    ratios.

                    The Portfolio generally invests principally in equity
                    securities but may also invest without limitation in
                    fixed-income obligations issued or guaranteed by an Asian
                    country or Australia or New Zealand when the Investment
                    Manager or the Sub-Advisor determine such investments to be
                    appropriate.

                    The Portfolio may invest up to 35% of its assets as follows:

                    - Equity, fixed-income or convertible securities (including
                      zero coupon securities) of companies located anywhere in
                      the world, including the United States.

                    - Forward currency contracts, which involve the purchase or
                      sale of a specific amount of foreign currency at the
                      current price with a delivery at a specified future date.
                      The Portfolio may use these contracts to hedge against
                      adverse price movements in its portfolio securities and
                      securities it intends to purchase and the currencies in
                      which they are denominated.

                    The Portfolio may invest up to 5% of its assets in put and
                    call options with respect to foreign currencies.

                    The Portfolio may invest up to 10% of its assets in
                    securities issued by other investment companies. The
                    Investment Manager and/or Sub-Advisor may view these
                    investments as necessary or advisable to participate in
                    certain foreign markets where foreigners are prohibited from
                    investing directly in the securities of individual companies
                    without regulatory approval.

                    The Portfolio may invest in warrants and acquire warrants
                    attached to other securities.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio relates to
                    the Portfolio's investments in the Pacific region. In
                    particular, adverse political, social or economic
                    developments in the Pacific region or in a particular
                    Pacific country could cause a substantial decline in the
                    value of the Portfolio.

                    The Portfolio's investments in common stock are also subject
                    to the risks that affect all common stocks. In particular,
                    stock prices can fluctuate widely in response to activities
                    specific to the issuer as well as general market economic
                    and political conditions.

                    In addition, the Portfolio is subject to the risks
                    associated with foreign securities generally. These risks
                    include among other things the possibility that the
                    Portfolio could be adversely affected by changes in currency
                    exchange rates. The Portfolio may invest a substantial
                    portion of its assets in developing countries. These
                    investments carry greater risks than those associated with
                    investment in more developed countries.

                    In addition, the Portfolio's investments in fixed-income
                    securities are subject to two types of risk: credit risk and
                    interest rate risk.

                    The performance of the Portfolio also will depend on whether
                    the Sub-Advisor is successful in pursuing the Portfolio's
                    investment strategy. In addition, the Portfolio is subject
                    to other risks from its permissible investments. For
                    information about these risks, as well as more detailed

                       Class X and Class Y shares are invested in the same
                       portfolio of securities. However, the returns for
                       Class Y shares would differ from those of Class X to the
                       extent the Classes have different expenses.

THE EQUITY PORTFOLIO

[ICON]              INVESTMENT OBJECTIVES
--------------------------------------------------------------------------------
                    The Equity Portfolio seeks as a primary objective growth of
                    capital through investments in common stocks of companies
                    believed by the Investment Manager to have potential for
                    superior growth. As a secondary objective the Equity
                    Portfolio seeks income but only when consistent with its
                    primary objective.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in equity securities and securities convertible into
                    equity securities. In selecting investments, the "Investment
                    Manager," Morgan Stanley Dean Witter Advisors Inc., may
                    employ valuation models based on various economic and market
                    indicators. The Investment Manager currently utilizes a
                    process, known as sector rotation, that emphasizes industry
                    selection over individual company selection. The Investment
                    Manager invests in those industries that it believes will
                    have the strongest relative earnings growth potential given
                    the projected economic outlook. After selecting the
                    Portfolio's target industries, the Investment Manager then
                    selects specific companies within those industries whose
                    prospects are deemed attractive after assessing company
                    fundamentals and valuation screens.

                    The Investment Manager utilizes a sector rotation process
                    designed to respond to changing economic cycles by
                    proactively investing in industries that the Investment
                    Manager believes to be positioned to benefit from the
                    current phase of the economic cycle. First, the Investment
                    Manager attempts to identify at what stage of the business
                    cycle the economy is in and which industries have
                    historically outperformed the overall market during that
                    stage of the cycle. To accomplish that task, the Investment
                    Manager establishes an economic forecast based on its short
                    term and long term views of the domestic and global economic
                    cycles. As part of this process, the Investment Manager will
                    attempt to identify secular trends, such as shifting
                    demographics or technological developments, that could add
                    clarity to its analysis. Also considered are competitive
                    industry variables, such as supply and demand, pricing
                    trends and new product cycles.

                    The Portfolio may invest up to 35% of its assets in
                    corporate debt securities (including zero coupon securities)
                    rated Aa or better by Moody's or AA or better by S&P, U.S.
                    Government securities, issued or guaranteed as to principal
                    and interest by the U.S. Government, its agencies or
                    instrumentalities, and preferred stocks.

                    The Portfolio may invest in securities of Canadian issuers
                    registered under the Securities Exchange Act of 1934 or
                    American Depository Receipts.

                                                                              31

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objectives. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common stock.
                    In particular the price of common stocks may fluctuate
                    widely in response to activities specific to the company as
                    well as general market, economic and political conditions.
                    Stocks of small and medium capitalization companies in which
                    the Portfolio may invest pose greater risk of volatility
                    than is customarily associated with larger established
                    companies as well as certain other additional risks.

                    Another principal risk relates to the Portfolio's
                    investments in fixed-income securities. Fixed-income
                    securities involve credit risk and interest rate risk.
                    Credit risk relates to the possibility that an issuer could
                    default on its obligation to pay principal and/or interest.
                    Interest rate risk relates to the possibility that the value
                    of securities may be adversely affected by fluctuations in
                    interest rates.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.

                       Class X and Class Y shares are invested in the same
                       portfolio of securities. However, the returns for
                       Class Y shares would differ from those of Class X to the
                       extent the Classes have different expenses.

THE S&P 500 INDEX PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    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
                    Standard & Poor's-Registered Trademark- 500 Composite Stock
                    Price Index.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------

                    The Portfolio will normally invest at least 80% of its total
                    assets in common stocks included in the S&P 500 Index. The
                    "Investment Manager," Morgan Stanley Dean Witter Advisors
                    Inc., "passively" manages the Portfolio's assets by
                    investing in stocks in approximately the same proportion as
                    they are represented in the S&P 500 Index. For example,
                    where the common stock of a specific company represents five
                    percent of the Index, the Investment Manager typically will
                    invest five percent of the Portfolio's assets in that stock.
                    The S&P 500 Index is a well-known stock market index that
                    includes common stocks of 500 companies representing a
                    significant portion of the market value of all common stocks
                    publicly traded in the United States.

                    The Portfolio may purchase and sell stock index futures to
                    simulate investment in the S&P 500. Generally stock index
                    futures may be employed to provide liquidity necessary to
                    meet anticipated redemptions or for day-to-day operating
                    purposes.

                    The Portfolios may invest in securities referred to as SPDRs
                    (known as "spiders") that are designed to track the S&P 500
                    Index. SPDRs represent an ownership interest in the SPDR
                    Trust, which holds a portfolio of common stocks that closely
                    tracks the price performance and dividend yield of the S&P
                    500 Index. SPDRs trade on the American Stock Exchange like
                    shares of common stock. The Portfolio may invest up to 10%
                    of its total assets in the aggregate in SPDRs.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its

                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investing in the Portfolio is associated
                    with its common stock investments. In general, stock values
                    fluctuate in response to activities specific to the issuer,
                    as well as general market, economic and political
                    conditions. Stock prices can fluctuate widely in response to
                    these factors.

                    Another risk of investing in the Portfolio arises from its
                    operation as a "passively" managed index fund. As such, the
                    adverse performance of a particular stock ordinarily will
                    not result in the elimination of the stock from the
                    Portfolio. The Portfolio will remain invested in common
                    stocks even when stock prices are generally falling.
                    Ordinarily, the Investment Manager will not sell the
                    Portfolio's securities except to reflect additions or
                    deletions of the stocks that comprise the S&P 500 Index, or
                    as may be necessary to raise cash to pay Portfolio
                    shareholders who sell (redeem) Portfolio shares.

                    The performance of the S&P 500 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 Portfolio and any
                    incremental operating costs borne by the Portfolio (E.G.,
                    management fee, transfer agency and accounting costs).
                    Accordingly, the performance of the Portfolio may not
                    correlate directly with the performance of the S&P 500
                    Index.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see

                    The bar chart and table below provide some indication of the
                    risks of investing in the S&P 500 Index Portfolio. The
                    Portfolio's past performance does not indicate how it will
                    perform in the future. The returns shown do not reflect fees
                    charged under the life insurance or annuity contracts, which
                    would lower the performance for all periods shown.

THE COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Competitive Edge "Best Ideas" Portfolio seeks long-term
                    capital growth.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 80% of its total
                    assets in common stock of companies included in the "Best
                    Ideas" subgroup of "Global Investing: The Competitive Edge,"
                    a research compilation assembled by Morgan Stanley Dean
                    Witter ("MSDW") Equity Research -- and other securities
                    selected by the Portfolio's "Investment Manager," Morgan
                    Stanley Dean Witter Advisors Inc.

                    THE COMPETITIVE EDGE "BEST IDEAS" LIST. 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.


                    MSDW Equity Research group's research analysts and
                    strategists presently evaluate approximately 2,100 companies
                    in 21 industry sectors worldwide. An initial comprehensive
                    review was conducted in October 1996 and identified 238 of
                    these companies 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
                    quarterly. From the Competitive Edge List, MSDW Equity
                    Research then assembles a subgroup of approximately 40
                    companies which it considers 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"). The Competitive Edge "Best Ideas" List is
                    updated continuously.


                    It is the intention of the Investment Manager that generally
                    at least 1% and not more than 5% of the Portfolio's assets
                    will be invested in each company on the Competitive Edge
                    "Best Ideas" List. The Portfolio will purchase any security
                    which is added to the Competitive Edge "Best Ideas" List,
                    and generally will sell a security which is eliminated from
                    the Competitive Edge "Best Ideas" List as soon as
                    practicable after the Competitive Edge "Best Ideas" List has
                    been updated by MSDW Equity Research. Accordingly,
                    securities may be purchased and sold by the Portfolio when
                    such purchases and sales would not be made under traditional
                    investment criteria.

                                                                              37
<PAGE>
                    The Portfolio may at times purchase securities that are not
                    included on the Competitive Edge "Best Ideas" List but are
                    on the Competitive Edge List or, in the event that the
                    Investment Manager believes that there are no suitable
                    securities on the Competitive Edge List, the Portfolio may
                    purchase securities outside the list. Securities that are
                    not on the Competitive Edge "Best Ideas" List generally will
                    not exceed 35% of the Portfolio's assets.

                    The Portfolio's investments may include forward currency
                    contracts which involve the purchase or sale of a specific
                    amount of foreign currency at a specified price with
                    delivery at a specified future date. The Portfolio may use
                    these contracts to hedge against adverse price movements in
                    its portfolio securities and the currencies in which they
                    are denominated.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common
                    stocks. In particular the prices of common stocks may
                    fluctuate widely in response to activities specific to the
                    company as well as general market, economic and political
                    conditions.

                    The Portfolio invests principally in securities included on
                    the Competitive Edge "Best Ideas" List which currently
                    consists of 40 companies. As a result of the small universe
                    of stocks in which the Portfolio invests it may be subject
                    to greater risks than would a more diversified company. At
                    times the Portfolio may be restricted in its ability to
                    purchase or sell securities on the Competitive Edge "Best
                    Ideas" List as a result of activities of affiliates of the
                    Investment Manager. In addition, performance of the
                    securities included in the List cannot be used to predict
                    the performance of the Portfolio, an actively managed mutual
                    fund.

                    The Competitive Edge "Best Ideas" List is not compiled with
                    any particular client or product in mind and is not, and
                    will not be, compiled with the Portfolio in mind. When
                    selecting the companies for the list, MSDW Equity Research
                    does not take into account country or currency risks, 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 Equity Research could at any time cease
                    publishing the Competitive Edge "Best Ideas" List. In that
                    event the Board of Trustees will make a determination of how
                    to proceed in the best interest of shareholders of the
                    Portfolio consistent with the Portfolio's investment
                    objective.

                    The activities of affiliates of the Investment Manager,
                    including but not limited to Dean Witter Reynolds Inc. or
                    Morgan Stanley & Co. Incorporated, may from time to time
                    limit the Portfolio's ability to purchase or sell securities
                    on the Competitive Edge "Best Ideas" List. In addition, the
                    List is available to other clients of MSDW

 38
<PAGE>
                    and its affiliates, including the Investment Manager, as
                    well as the Portfolio. The list is also subject to
                    restrictions related to MSDW's other businesses, and
                    particular securities may or may not be on the list due to
                    other business concerns of, or legal restrictions applicable
                    to, MSDW.

                    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 Portfolio may invest a substantial portion of its assets
                    in foreign securities. Foreign securities investments may be
                    adversely affected by changes in currency exchange rates. In
                    addition, investment in foreign securities may be adversely
                    affected by among other things political, social and
                    economic developments abroad.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed

                    The bar chart and table below provide some indication of the
                    risks of investing in the Competitive Edge "Best Ideas"
                    Portfolio. The Portfolio's past performance does not
                    indicate how it will perform in the future. The returns
                    shown do not reflect fees charged under the life insurance
                    or annuity contracts, which would lower the performance for
                    all periods shown.

                    During the period shown in the bar chart, the highest return
                    for a calendar quarter was 18.60% (quarter ended December

THE AGGRESSIVE EQUITY PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Aggressive Equity Portfolio seeks long-term capital
                    growth.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------
                    The Portfolio will normally invest at least 65% of its total
                    assets in common stocks and other equity securities of
                    companies that the "Investment Manager," Morgan Stanley Dean
                    Witter Advisors Inc., believes offer the potential for
                    superior earnings growth. The Portfolio's other equity
                    securities may include preferred stocks, securities
                    convertible into common stock, rights and warrants. No more
                    than 25% of the Portfolio's assets may be invested in
                    foreign equity or fixed-income securities denominated in a
                    foreign currency and traded primarily in non-U.S. markets.

                    The Investment Manager utilizes a process, known as sector
                    rotation, that emphasizes industry selection over individual
                    company selection. The Investment Manager invests in those
                    industries that it believes will have the strongest relative
                    earnings growth potential given the projected economic
                    outlook. After selecting the Portfolio's target industries,
                    the Investment Manager selects specific companies within
                    those industries whose prospects are deemed attractive after
                    assessing company fundamentals and valuation screens.
                    Company selection is based on the Investment Manager's own
                    analysis and research reports as well as analysis from the
                    equity research departments of recognized securities firms.
                    The Investment Manager has no general criteria as to the
                    market capitalization or asset size of the companies
                    selected for investment and, accordingly, the Portfolio may
                    invest in small and medium-sized companies in addition to
                    larger, more established companies.

                    The Investment Manager utilizes a sector rotation process
                    designed to respond to changing economic cycles by
                    proactively investing in industries that the Investment
                    Manager believes to be positioned to benefit from the
                    current phase of the economic cycle. First, the Investment
                    Manager attempts to identify at what stage of the business
                    cycle the economy is in and which industries have
                    historically outperformed the overall market during that
                    stage of the cycle. To accomplish that task, the Investment
                    Manager establishes an economic forecast based on its short
                    term and long term views of the domestic and global economic
                    cycles. As part of this process, the Investment Manager will
                    attempt to identify secular trends, such as shifting
                    demographics or technological developments, that could add
                    clarity to its analysis. Also considered are competitive
                    industry variables, such as supply and demand, pricing
                    trends and new product cycles.

                    The Portfolio may invest up to 35% of its assets as follows:

                    - (a) fixed-income securities of U.S. companies,
                      (b) fixed-income securities of foreign companies and
                      governments and international organizations, (c) U.S.
                      Government securities, issued or guaranteed as to
                      principal and interest by the U.S. Government, its
                      agencies or instrumentalities, and (d) real estate
                      investment trusts (commonly known as "REITs"). However, no
                      more than 5% of the Portfolio's assets may be invested in
                      debt securities rated lower than investment grade, or if
                      unrated of comparable quality as determined by the
                      Investment Manager (commonly known as "junk bonds").

                                                                              41
<PAGE>
                    - Forward currency contracts, which involve the purchase or
                      sale of a specific amount of foreign currency at a
                      specified price with delivery at a specified future date.
                      The Portfolio may use these contracts to hedge against
                      adverse price movements in its portfolio securities and
                      the currencies in which they are denominated.

                    - Put and call options and futures with respect to financial
                      instruments, stock and interest rate indexes and foreign
                      currencies (limit of 5% of its assets for the purchase of
                      put and call options). Options and futures may be used to
                      seek higher returns to seek to protect against a decline
                      in security or currency prices or an increase in prices of
                      securities or currencies that may be purchased.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common
                    stocks. In particular, the prices of common stocks may
                    fluctuate widely in response to activities specific to the
                    company as well as general market, economic and political
                    conditions.

                    The Portfolio may invest a substantial portion of its assets
                    in securities issued by small and medium sized companies.
                    Investment in small and medium size companies involves
                    greater risk of volatility than is customarily associated
                    with investment in larger established companies as well as
                    certain other additional risks.

                    The Portfolio is subject to the risks associated with
                    foreign securities. These risks include, among other things,
                    the possibility that the Portfolio could be adversely
                    affected by changes in currency exchange rates.

                    The Portfolio is also subject to the risks of investing in
                    convertible securities. These securities may carry risks
                    associated with both common stock and fixed-income
                    securities.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.


                    The Portfolio commenced operations on May 3, 1999 and prior
                    to the date of this PROSPECTUS did not have a full calendar
                    year of performance to report.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES

--------------------------------------------------------------------------------

                    The Portfolio will normally invest at least 65% of its total
                    assets in common stocks and investment grade convertible
                    securities of companies located throughout the world that
                    are engaged in the communications and information industry.
                    The Portfolio normally holds common stocks and other equity
                    securities of companies located in at least three countries,
                    one of which is the United States. It may invest up to 50%
                    of its assets in the securities (including depository
                    receipts) of foreign companies; however, it will not invest
                    more than 25% of its assets in any one foreign country. In
                    addition, the Portfolio will not invest more than 10% of its
                    assets in convertible securities. In deciding which
                    securities to buy, hold or sell, the "Investment Manager,"
                    Morgan Stanley Dean Witter Advisors Inc., considers
                    business, economic and political conditions.



                    A company is considered to be in the communications and
                    information industry if it derives at least 35% of its
                    revenues or earnings from, or devotes at least 35% of its
                    assets to:



                    - designing, developing, manufacturing, providing or
                      enabling the following products and services: regular
                      telephone service; communications equipment and services;
                      electronic components and equipment; broadcasting;
                      computer equipment, enabling software, mobile
                      communications and cellular radio/paging; electronic mail
                      and other electronic data transmission services;
                      networking and linkage of word and data processing
                      systems; publishing and information systems; video text
                      and teletext; and emerging technologies combining
                      telephone, television and/or computer systems; or



                    - the creation, packaging, distribution, and ownership of
                      entertainment and information programming.



                    The Portfolio may invest up to 35% of its total assets in
                    investment grade corporate fixed-income securities and U.S.
                    government securities. The Portfolio's fixed-income
                    investments may include zero coupon securities.



[ICON]              SUMMARY OF PRINCIPAL RISKS

--------------------------------------------------------------------------------

                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.


                                                                              43
<PAGE>

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common
                    stocks. In particular, the prices of common stocks may
                    fluctuate widely in response to activities specific to the
                    company as well as general market, economic and political
                    conditions.



                    The Portfolio concentrates its investments in the
                    communications and information industry. Because of this
                    concentration, the value of the Portfolio's shares may be
                    more volatile than that of mutual funds that do not
                    similarly concentrate their investments. The communications
                    and information industry may be subject to greater changes
                    in governmental policies and governmental regulation than in
                    many other industries in the United States and worldwide.
                    Regulatory approval requirements, ownership restrictions and
                    restrictions on rates of return and types of services that
                    may be offered may materially affect the products and
                    services of this industry. Additionally, the products and
                    services of companies in this industry may be subject to
                    faster obsolescence as a result of greater competition,
                    advancing technological developments, and changing market
                    and consumer preferences. As a result, the securities of
                    companies in this industry may exhibit greater price
                    volatility than those of companies in other industries.



                    The Portfolio is subject to the risks associated with
                    foreign securities. These risks include, among other things,
                    the possibility that the Portfolio could be adversely
                    affected by changes in currency exchange rates.



                    The Portfolio is also subject to the risks of investing in
                    convertible securities. These securities may carry risks
                    associated with both common stock and fixed-income
                    securities.



                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.



                    The Portfolio was recently organized and as of the date of
                    this PROSPECTUS had no historical performance to report.

THE STRATEGIST PORTFOLIO

[ICON]              INVESTMENT OBJECTIVE
--------------------------------------------------------------------------------
                    The Strategist Portfolio seeks 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.

[ICON]              PRINCIPAL INVESTMENT STRATEGIES
--------------------------------------------------------------------------------

                    The "Investment Manager," Morgan Stanley Dean Witter
                    Advisors Inc., will actively allocate the Portfolio's assets
                    among the major asset categories of equity securities,
                    fixed-income securities and money market instruments. Assets
                    are allocated by the Investment Manager based on among other
                    things, its assessment of economic and market trends on
                    different sectors of the market. There is no limit as to the
                    percentage of assets that may be allocated to any one asset
                    class. The Investment Manager does not, however, currently
                    intend to write covered call or put options.

                    Within the equity sector, the Investment Manager actively
                    allocates funds to those economic sectors it expects to
                    benefit from major trends and to individual stocks which it
                    considers to have superior investment potential.

                    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, including short-term and
                    intermediate-term bonds.

                    Within the money market sector of the market, the Investment
                    Manager seeks to maximize returns by exploiting spreads
                    among short-term instruments.

                    Securities in which the Portfolio may invest include common
                    stocks, preferred stocks, convertible securities, investment
                    grade debt securities (including zero coupon securities),
                    U.S. Government securities, real estate investment trusts
                    (commonly known as "REITs") and money market instruments.
                    The Portfolio is not limited as to the maturities of the
                    U.S. government securities and other debt securities in
                    which it may invest.

                    The Portfolio may invest up to 20% of its assets in
                    securities issued by foreign governments and foreign private
                    issuers but not more than 10% of its assets in securities
                    denominated in a foreign currency.

[ICON]              SUMMARY OF PRINCIPAL RISKS
--------------------------------------------------------------------------------
                    There is no assurance that the Portfolio will achieve its
                    investment objective. The Portfolio's share price will
                    fluctuate with changes in the market value of its portfolio
                    securities. When you sell Portfolio shares, they may be
                    worth less than what you paid for them and, accordingly, you
                    can lose money investing in this Portfolio.

                    A principal risk of investment in the Portfolio is
                    associated with the Portfolio's investments in common
                    stocks. In particular, the prices of common stocks may
                    fluctuate widely in response to activities specific to the
                    company as well as general market, economic and political
                    conditions.

                                                                              45

                    The Portfolio's investment in fixed-income securities are
                    subject to credit risk and interest rate risk. Credit risk
                    refers to a possibility that the issuer of a security will
                    be unable to make interest payments and/or repay the
                    principal on its debts. Interest rate risk refers to
                    fluctuations in the value of a fixed-income security
                    resulting from changes in the general level of interest
                    rates.

                    The Portfolio is also subject to the risks of investing in
                    convertible securities. These securities may carry risks
                    associated with both common stock and fixed-income
                    securities.

                    The performance of the Portfolio also will depend on whether
                    the Investment Manager is successful in pursuing the
                    Portfolio's investment strategy. In addition, the Portfolio
                    is subject to other risks from its permissible investments.
                    For information about these risks, as well as more detailed
                    information about the risks summarized in this section, see
                    the "Additional Risk Information" section.

[ICON]              PAST PERFORMANCE
--------------------------------------------------------------------------------
                    The bar chart and table below provide some indication of the
                    risks of investing in the Strategist Portfolio. The
                    Portfolio's past performance does not indicate how it will
                    perform in the future. The returns shown do not reflect fees
                    charged under the life insurance or annuity contracts, which
                    would lower the performance for all periods shown.

                    quarter was -8.25% (quarter ended September 30, 1990).
                    *  The Fund commenced offering Class Y shares of each

                       (and the Table below) are for Class X shares of the
                       Portfolio (which are offered in a separate prospectus).
                       Class X and Class Y shares are invested in the same
                       portfolio of securities. However, the returns for
                       Class Y shares would differ from those of Class X to the
                       extent the Classes have different expenses.

ADDITIONAL INVESTMENT STRATEGY INFORMATION

                    This section provides additional information relating to
                    each Portfolio's principal strategies.

                    INVESTMENT DISCRETION. In pursuing each Portfolio's
                    investment objective, the Investment Manager has
                    considerable leeway in deciding which investments it buys,
                    holds or sells on a day-to-day basis - and which trading
                    strategies it uses. For example, the Investment Manager in
                    its discretion may determine to use some permitted trading
                    strategies while not using others. The Sub-Advisor has a
                    similar degree of discretion.

                    DEFENSIVE INVESTING. Each Portfolio (other than the Money
                    Market Portfolio and the S&P 500 Index Portfolio) may take
                    temporary "defensive" positions in attempting to respond to
                    adverse market conditions. Each Portfolio may invest any
                    amount of its assets in cash or money market instruments in
                    a defensive posture when the Investment Manager or
                    Sub-Advisor, as the case may be, believes it advisable to do
                    so. Although taking a defensive posture is designed to
                    protect the Portfolio from an anticipated market downturn,
                    it could have the effect of reducing the benefit of an
                    upswing in the market. When a Portfolio takes a defensive
                    position, it may not achieve its investment objective(s).

                    INVESTMENT POLICIES. The percentage limitations relating to
                    the composition of a Portfolio apply at the time a Portfolio
                    acquires an investment and refer to the Portfolio's net
                    assets, unless otherwise noted. Subsequent percentage
                    changes that result from market fluctuations will not
                    require a Portfolio to sell any Portfolio security. A
                    Portfolio may change its principal investment strategies
                    without shareholder approval; however you would be notified
                    of any change.


                    PORTFOLIO TURNOVER. Each Portfolio, other than the S&P 500
                    Index Portfolio and the Competitive Edge "Best Ideas"
                    Portfolio, may engage in active and frequent trading of its
                    portfolio securities. The Financial Highlights Table at the
                    end of this PROSPECTUS shows recent portfolio turnover rates
                    for each Portfolio (other than the Information Portfolio,
                    which prior to the date of this PROSPECTUS had not commenced
                    operations). A portfolio turnover rate of 200%, for example,
                    is equivalent to the Portfolio buying and selling all of its
                    securities two times during the course of the year. A high
                    portfolio turnover rate (over 100%) could result in high
                    brokerage costs.

ADDITIONAL RISK INFORMATION

                    This section provides additional information relating to the
                    principal risks of investing in the Portfolios.

                    Shares of the Portfolios are not bank deposits and are not
                    guaranteed or insured by the FDIC or any other government
                    agency.

                                            *    *    *

                    The risks set forth below are applicable to a Portfolio only
                    to the extent the Portfolio invests in the investment
                    described. See "The Portfolios" for a description of the
                    investments which each Portfolio may make.

                    FIXED-INCOME SECURITIES. All fixed-income securities are
                    subject to two types of risk: credit risk and interest rate
                    risk. Credit risk refers to the possibility that the issuer
                    of a security will be unable to make interest payments
                    and/or repay the principal on its debt.

                    Interest rate risk refers to fluctuations in the value of a
                    fixed-income security resulting from changes in the general
                    level of interest rates. When the general level of interest
                    rates goes up, the prices of most fixed-income securities go
                    down. When the general level of interest rates goes down,
                    the prices of most fixed-income securities go up. (Zero
                    coupon securities are typically subject to greater price
                    fluctuations than comparable securities that pay interest.)
                    Accordingly, a rise in the general level of interest rates
                    may cause the price of a Portfolio's fixed-income securities
                    to fall substantially. As merely illustrative of the
                    relationship between fixed-income securities and interest
                    rates, the following table shows how interest rates affect
                    bond prices.

</TABLE>

                    Coupons reflect yields on Treasury securities as of
                    December 31, 1999. The table is not representative of price
                    changes for mortgage-backed securities principally because
                    of prepayments, and it is not representative of junk bonds.
                    In addition, the table is an illustration and does not
                    represent expected yields or share price changes of any
                    Morgan Stanley Dean Witter mutual fund.

                    MORTGAGE-BACKED SECURITIES. Mortgage-backed securities have
                    different risk characteristics than traditional debt
                    securities. Although generally the value of fixed-income
                    securities increases during periods of falling interest
                    rates and decreases during periods of rising interest rates,
                    this is not always the case with mortgage-backed securities.
                    This is due to the fact that principal on underlying
                    mortgages may be prepaid at any time as well as other
                    factors. Generally, prepayments will increase during a
                    period of falling interest rates and decrease during a
                    period of rising interest rates. The rate of prepayments
                    also may be influenced by economic

                                                                              49
<PAGE>
                    and other factors. Prepayment risk includes the possibility
                    that, as interest rates fall, securities with stated
                    interest rates may have the principal prepaid earlier than
                    expected, requiring the Fund to invest the proceeds at
                    generally lower interest rates.

                    Investments in mortgage-backed securities are made based
                    upon, among other things, expectations regarding the rate of
                    prepayments on underlying mortgage pools. Rates of
                    prepayment, faster or slower than expected by the Investment
                    Manager, could reduce a Portfolio's yield, increase the
                    volatility of the Portfolio and/ or cause a decline in net
                    asset value. Certain mortgage-backed securities in which a
                    Portfolio may invest may be more volatile and less liquid
                    than other traditional types of debt securities.

                    JUNK BONDS. A Portfolio's investments in securities rated
                    lower than investment grade or if unrated of comparable
                    quality as determined by the Investment Manager or
                    Sub-Advisor (commonly known as "junk bonds") pose
                    significant risks. The prices of junk bonds are likely to be
                    more sensitive to adverse economic changes or individual
                    corporate developments than higher rated securities. During
                    an economic downturn or substantial period of rising
                    interest rates, junk bond issuers and, in particular, highly
                    leveraged issuers may experience financial stress that would
                    adversely affect their ability to service their principal
                    and interest payment obligations, to meet their projected
                    business goals or to obtain additional financing. In the
                    event of a default, the Portfolio may incur additional
                    expenses to seek recovery. The secondary market for junk
                    bonds 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 Rule 144A
                    securities could have the effect of increasing the level of
                    Portfolio illiquidity to the extent a Portfolio may be
                    unable to find qualified institutional buyers interested in
                    purchasing the 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 junk bonds at certain
                    times and could make it difficult for the Portfolios to sell
                    certain securities. In addition, periods of economic
                    uncertainty and change probably would result in an increased
                    volatility of market prices of high yield securities and a
                    corresponding volatility in a Portfolio's net asset value.

                    SECURITIES RATED IN THE LOWEST INVESTMENT GRADE
                    CATEGORY. Investments in the fixed-income securities rated
                    in the lowest investment grade category by Moody's or S&P
                    may have speculative characteristics and therefore changes
                    in economic 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.

                    FOREIGN SECURITIES. Foreign securities involve risks in
                    addition to the risks associated with domestic securities.
                    One additional risk is currency risk. While the price of
                    Portfolio shares is quoted in U.S. dollars, a Portfolio
                    generally converts U.S. dollars to a foreign market's local
                    currency to purchase a security in that market. If the value
                    of that local currency falls relative to the U.S. dollar,
                    the U.S. dollar value of the foreign security will decrease.
                    This is true even if the foreign security's local price
                    remains unchanged.

                    Foreign securities (including depository receipts) also have
                    risks related to economic and political developments abroad,
                    including effects of foreign social, economic or political
                    instability. Foreign companies, in general, are not subject
                    to the regulatory requirements of U.S. companies and, as
                    such, there may be less publicly available information about
                    these companies. Moreover, foreign accounting, auditing and
                    financial reporting standards generally are different from
                    those applicable to U.S. companies. Finally, in the event of
                    a default of any foreign debt obligations, it may be more
                    difficult for the Fund to obtain or enforce a judgment
                    against the issuers of the securities.

                    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
                    U.S. counterparts.

                    The foreign securities in which certain of the Portfolios
                    may invest (in particular the Pacific Growth Portfolio) may
                    be issued by companies 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 that trade a small number of securities.
                    Prices of these securities tend to be especially volatile
                    and, in the past, securities in these countries have offered
                    greater potential loss (as well as gain) than securities of
                    companies located in developed countries.

                    SMALL & MEDIUM CAPITALIZATION COMPANIES. A Portfolio's
                    investments in smaller and medium sized companies carry more
                    risk than investments in larger companies. While some of a
                    Portfolio's holdings in these companies may be listed on a
                    national securities exchange, such securities are more
                    likely to be traded in the over-the-counter market. The low
                    market liquidity of these securities may have an adverse
                    impact on a Portfolio's ability to sell certain securities
                    at favorable prices and may also make it difficult for a
                    Portfolio to obtain market quotations based on actual
                    trades, for purposes of valuing a Portfolio's securities.
                    Investing in lesser-known, smaller and medium capitalization
                    companies involves greater risk of volatility of a
                    Portfolio's net asset value than is customarily associated
                    with larger, more established companies. Often smaller and
                    medium capitalization companies and the industries in which
                    they are focused are still evolving and, while this may
                    offer better growth potential than larger, more established
                    companies, it also may make them more sensitive to changing
                    market conditions.

                    OPTIONS AND FUTURES. If a Portfolio invests in options
                    and/or futures, its participation in these markets would
                    subject the Portfolio to certain risks. The Investment
                    Manager's or the Sub-Advisor's predictions of movements in
                    the direction of the stock, bond, currency or interest rate
                    markets may be inaccurate, and the adverse consequences to
                    the Portfolio (e.g., a reduction in the Portfolio's net
                    asset value or a reduction in the amount of income available
                    for distribution) may leave the Portfolio in a worse
                    position than if these strategies were not used. Other risks
                    inherent in the use of options and futures include, for
                    example, the possible imperfect correlation between the
                    price of options and futures contracts and movements in the
                    prices of the securities being hedged, and the possible
                    absence of

                                                                              51
<PAGE>
                    a liquid secondary market for any particular instrument.
                    Certain options may be over-the-counter options, which are
                    options negotiated with dealers; there is no secondary
                    market for these investments.

                    FORWARD CURRENCY CONTRACTS. A Portfolio's participation in
                    forward currency contracts also involves risks. If the
                    Investment Manager or Sub-Advisor employs a strategy that
                    does not correlate well with the Portfolio's investments or
                    the currencies in which the investments are denominated,
                    currency contracts could result in a loss. The contracts
                    also may increase the Portfolio's volatility and may involve
                    a significant risk.

                    REAL ESTATE INVESTMENT TRUSTS ("REITS"). REITs pool
                    investors funds for investments primarily in commercial real
                    estate properties. Like mutual funds, REITs have expenses,
                    including advisory and administration fees that are paid by
                    its shareholders. As a result, you will absorb duplicate
                    levels of fees when a Portfolio invests in REITs. The
                    performance of any Portfolio REIT holdings ultimately
                    depends on the types of real property in which the REITs
                    invest and how well the property is managed. A general
                    downturn in real estate values also can hurt REIT
                    performance.

PORTFOLIO MANAGEMENT

                    Morgan Stanley Dean Witter Advisors Inc. is the Investment
                    Manager to each Portfolio. Each Portfolio has retained the
                    Investment Manager to provide administrative services,
                    manage its business affairs and (except for the Pacific
                    Growth and European Growth Portfolios) invest its assets,
                    including the placing of orders for the purchase and sale of
                    portfolio securities. The Investment Manager is a wholly-
                    owned subsidiary of Morgan Stanley Dean Witter & Co., a
                    preeminent global financial services firm that maintains
                    leading market positions in each of its three primary
                    businesses: securities, asset management and credit
                    services. Its main business office is located at Two World
                    Trade Center, New York, NY 10048.

                    Each of the Pacific Growth and European Growth Portfolios
                    has retained the Investment Manager to supervise the
                    investment of its assets. The Investment Manager has, in
                    turn, contracted with the Sub-Advisor - Morgan Stanley Dean
                    Witter Investment Management Inc. - to invest each
                    Portfolio's assets, including the placing of orders for the
                    purchase and sale of portfolio securities. The Sub-Advisor
                    also is a subsidiary of Morgan Stanley Dean Witter & Co. Its
                    main business office is located at 1221 Avenue of the
                    Americas, New York, NY 10020.


                    Each Portfolio pays the Investment Manager a monthly
                    management fee as full compensation for the services and

SHAREHOLDER INFORMATION

[ICON]              PRICING FUND SHARES
--------------------------------------------------------------------------------
                    The price of shares of each Portfolio called "net asset
                    value," is based on the value of its portfolio securities.

                    The net asset value for each Portfolio is calculated once
                    daily at 4:00 p.m. Eastern time on each day the New York
                    Stock Exchange is open (or, on days when the New York Stock
                    Exchange closes prior to 4:00 p.m., at such earlier time).
                    Shares will not be priced on days that the New York Stock
                    Exchange is closed.

                    The value of each Portfolio's securities (other than the
                    Money Market Portfolio) is based on the securities' market
                    price when available. When a market price is not readily
                    available, including circumstances under which the
                    Investment Manager (or, if applicable, the Sub-Advisor)
                    determines that a security's market price is not accurate, a
                    portfolio security is valued at its fair value, as
                    determined under procedures established by the Fund's Board
                    of Trustees. In these cases, the applicable Portfolio's net
                    asset value will reflect certain portfolio securities' fair
                    value rather than their market price. In addition, with
                    respect to securities that are primarily listed on foreign
                    exchanges, the value of the Portfolio's investment
                    securities may change on days when shareholders will not be
                    able to purchase or sell their shares.

                    An exception to the general policy of using market prices
                    concerns each Portfolio's short-term debt portfolio
                    securities. Debt securities with remaining maturities of
                    sixty days or less at the time of purchase are valued at
                    amortized cost. However, if the cost does not reflect the
                    securities' market value, these securities will be valued at
                    their fair value.

                    The Money Market Portfolio utilizes amortized cost in
                    determining the value of its portfolio securities. The
                    amortized cost valuation method involves valuing a debt
                    obligation in reference to its acquisition cost rather than
                    market forces.

[ICON]              PLAN OF DISTRIBUTION
--------------------------------------------------------------------------------

                    Each Portfolio has adopted a Plan of Distribution in
                    accordance with Rule 12b-1 under the Investment Company Act
                    of 1940. Class Y shares of each Portfolio are subject to a
                    distribution (12b-1) fee of 0.25% of the average daily net
                    assets of the Class. The Plan allows Class Y shares of each
                    Portfolio to bear distribution fees in connection with the
                    sale and distribution of Class Y shares. It also allows each
                    Portfolio to pay for services to Class Y shareholders.
                    Because these fees are paid out of the assets of each
                    Portfolio's Class Y shares on an ongoing basis, over time
                    these fees will increase the cost of your investment and may
                    cost you more than paying other types of sales charges.

[ICON]              DISTRIBUTIONS
--------------------------------------------------------------------------------
                    Each Portfolio passes substantially all of its earnings from
                    income and capital gains along to its investors as
                    "distributions." Each Portfolio earns income from stocks
                    and/or interest from fixed-income investments. These amounts
                    are passed along to the appropriate Portfolio investors as
                    "income dividend distributions." Each Portfolio realizes
                    capital gains whenever it sells securities for a higher
                    price than it paid for them. These amounts may be passed
                    along as "capital gain distributions."

                    Dividends from net investment income and capital gains
                    distributions, if any, are declared and paid as follows:

FINANCIAL HIGHLIGHTS

          The financial highlights table is intended to help you understand the
          financial performance of each Portfolio's Class X shares for the past
          5 fiscal years of the Fund. The Fund commenced offering Class Y shares
          of each Portfolio on May 1, 2000. Prior to that date, the Fund issued
          one Class of shares of each Portfolio, which, as of May 1, 2000, have
          been designated Class X shares. Certain information reflects financial
          results for a single Portfolio share. The total returns in the tables
          represent the rate an investor would have earned or lost on an
          investment in each Portfolio (assuming reinvestment of all dividends
          and distributions).

          The information for each of the periods through December 31, 1999 has
          been audited by PricewaterhouseCoopers LLP, independent accountants,
          whose report, along with the Fund's financial statements, is included
          in the annual report, which is available upon request. The information
          for the six-month period ended June 30, 2000 is unaudited.

Further information about the performance of the Portfolios of the Fund is
contained in the annual report. 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 issued by the applicable
insurance company for a description of charges which are applicable thereto.
These charges are not reflected in the financial highlights below. Inclusion of
any of these charges would reduce the total return figures for all periods
shown. The financial highlights table does not cover the Information Portfolio,
which had not commenced operations prior to the date of this PROSPECTUS.

on February 25, 1983 under the name Dean Witter Variable Annuity Investment
Series and is a trust of the type commonly referred to as a Massachusetts
Business Trust. Effective February 23, 1988, the Fund's name was changed to Dean
Witter Variable Investment Series. On September 1, 1995, the name of the MANAGED
ASSETS PORTFOLIO was changed to the STRATEGIST PORTFOLIO. Effective June 22,
1998, the Fund's name was changed to Morgan Stanley Dean Witter Variable
Investment Series.

II. DESCRIPTION OF THE FUND AND ITS INVESTMENTS AND RISKS
--------------------------------------------------------------------------------

A. CLASSIFICATION

    The Fund is an open-end, diversified management investment company.

B. ELIGIBLE PURCHASERS

    As discussed in each of the Class X and Class Y PROSPECTUSES, shares of the
Fund are sold only to particular insurance companies in connection with variable
annuity and/or variable life insurance contracts they issue. It is conceivable
that in the future it may become disadvantageous for both variable life
insurance and variable annuity contract separate accounts to invest in the same
underlying funds. Although neither the various insurance companies nor the Fund
currently foresee any such disadvantage, the Trustees intend to monitor events
in order to identify any material irreconcilable conflict between the interest
of variable annuity contract owners and variable life insurance contract owners
and to determine what action, if any, should be taken in response thereto.

C. INVESTMENT STRATEGIES AND RISKS

    The following discussion of each Portfolio's investment strategies and risks
should be read with the sections of the Fund's PROSPECTUS titled "Principal
Investment Strategies," "Principal Risks," "Additional Investment Strategy
Information" and "Additional Risk Information."

    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 fixed-income securities which are
convertible into common stock ("CONVERTIBLE SECURITIES"). In addition, each
Portfolio, other than the MONEY MARKET PORTFOLIO, may acquire convertible
securities through a distribution by a security held in its portfolio.
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 to 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. Convertible securities may be purchased by a
Portfolio at varying price levels above their investment values and/ or their
conversion values in keeping with the Portfolio's objective.


    FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS.  The SHORT-TERM BOND PORTFOLIO,
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, the AGGRESSIVE EQUITY PORTFOLIO, the INFORMATION PORTFOLIO and
the STRATEGIST


                                       4
<PAGE>

PORTFOLIO may enter into forward foreign currency exchange contracts ("FORWARD
CONTRACTS"): to facilitate settlement in an attempt to limit the effect of
changes in the relationship between the U.S. dollar and the foreign currency
during the period between the date on which the security is purchased or sold
and the date on which payment is made or received. In addition, the SHORT-TERM
BOND PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH
PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO, the AGGRESSIVE EQUITY PORTFOLIO and the INFORMATION PORTFOLIO may
enter into forward contracts as a hedge against fluctuations in future foreign
exchange rates. Each Portfolio may conduct its foreign currency exchange
transactions either on a spot (i.e., cash) basis at the spot rate prevailing in
the foreign currency exchange market, or through entering into forward contracts
to purchase or sell foreign currencies. A forward contract involves an
obligation to purchase or sell a specific 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. These contracts are traded
in the interbank market conducted directly between currency traders (usually
large commercial and investment banks) and their customers. Forward contracts
only will be entered into with United States banks and their foreign branches or
foreign banks whose assets total $1 billion or more. A forward contract
generally has no deposit requirement, and no commissions are charged at any
stage for trades.


    When the Fund's Investment Manager believes that a particular foreign
currency may experience a substantial movement against the U.S. dollar, it may
enter into a forward contract to purchase or sell, for a fixed amount of dollars
or other currency, the amount of foreign currency approximating the value of
some or all of a Portfolio's portfolio securities denominated in such foreign
currency. The Portfolios will also not enter into such forward contracts or
maintain a net exposure to such contracts where the consummation of the
contracts would obligate the Portfolio to deliver an amount of foreign currency
in excess of the value of the Portfolio's portfolio securities or other assets
denominated in that currency.

    The SHORT-TERM BOND PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the
EUROPEAN GROWTH PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the
AGGRESSIVE EQUITY PORTFOLIO also may from time to time utilize forward contracts
for other purposes. For example, they may be used to hedge a foreign security
held in the portfolio or a security which pays out principal tied to an exchange
rate between the U.S. dollar and a foreign currency, against a decline in value
of the applicable foreign currency. They also may be used to lock in the current
exchange rate of the currency in which those securities anticipated to be
purchased are denominated. At times, the Portfolios may enter into
"cross-currency" hedging transactions involving currencies other than those in
which securities are held or proposed to be purchased are denominated.

    A Portfolio will not enter into forward currency contracts or maintain a net
exposure to these contracts where the consummation of the contracts would
obligate the Portfolio to deliver an amount of foreign currency in excess of the
value of the Portfolio's portfolio securities.

    Although a Portfolio values its assets daily in terms of U.S. dollars, it
does not intend to convert its holdings of foreign currencies into U.S. dollars
on a daily basis. It will, however, do so from time to time, and investors
should be aware of the costs of currency conversion. Although foreign exchange
dealers do not charge a fee for conversion, they do realize a profit based on
the spread between the prices at which they are buying and selling various
currencies. Thus, a dealer may offer to sell a foreign currency to the Portfolio
at one rate, while offering a lesser rate of exchange should the Portfolio
desire to resell that currency to the dealer.

    A Portfolio may be limited in its ability to enter into hedging transactions
involving forward contracts by the Internal Revenue Code requirements relating
to qualification as a regulated investment company.

    Forward contracts may limit gains on portfolio securities that could
otherwise be realized had they not been utilized and could result in losses. The
contracts also may increase the Portfolio's volatility and may involve a
significant amount of risk relative to the investment of cash.


    OPTION AND FUTURES TRANSACTIONS.  Each of the following Portfolios may
engage in transactions in listed and OTC options: the SHORT-TERM BOND PORTFOLIO,
the QUALITY INCOME PLUS PORTFOLIO, the UTILITIES PORTFOLIO, the CAPITAL GROWTH
PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH


                                       5
<PAGE>

PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS"
PORTFOLIO, the AGGRESSIVE EQUITY PORTFOLIO, the INFORMATION PORTFOLIO and the
STRATEGIST PORTFOLIO. Listed options are issued or guaranteed by the exchange on
which they are traded 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 or currency 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 date 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 or
currency 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 or currency
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 or
currency from the OCC (in the U.S.) or other clearing corporation or exchange,
at the exercise price.


    COVERED CALL WRITING.  Each of the above-named Portfolios is permitted to
write covered call options on portfolio securities without limit. Each of the
SHORT-TERM BOND PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the EUROPEAN
GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the COMPETITIVE EDGE "BEST
IDEAS" PORTFOLIO and the AGGRESSIVE EQUITY PORTFOLIO may also write covered call
options on the U.S. dollar and foreign currencies in which its portfolio
securities are denominated, without limit.

    The Portfolio will receive from the purchaser, in return for a call it has
written, a "premium," I.E., the price of the option. Receipt of these premiums
may better enable the Portfolio to earn a higher level of current income than it
would earn from holding the underlying securities (or currencies) alone.
Moreover, the premium received will offset a portion of the potential loss
incurred by the Portfolio if the securities (or currencies) underlying the
option decline in value.

    The Portfolio may be required, at any time during the option period, to
deliver the underlying security (or currency) against payment of the exercise
price on any calls it has written. This obligation is terminated upon the
expiration of the option period or at such earlier time when the writer effects
a closing purchase transaction. A closing purchase transaction is accomplished
by purchasing an option of the same series as the option previously written.
However, once the Portfolio has been assigned an exercise notice, the Portfolio
will be unable to effect a closing purchase transaction.

    A call option is "covered" if the Portfolio owns the underlying security
subject to the option or has an absolute and immediate right to acquire that
security without additional cash consideration (or for additional consideration
(in cash, Treasury bills or other liquid portfolio securities) held in a
segregated account on the Portfolio's books) upon conversion or exchange of
other securities held in its portfolio. A call option is also covered if the
Portfolio holds a call on the same security as the call written where the
exercise price of the call held is (i) equal to or less than the exercise price
of the call written or (ii) greater than the exercise price of the call written
if the difference is maintained by the Portfolio in cash, Treasury bills or
other liquid portfolio securities in a segregated account on the Portfolio's
books.

    Options written by the Portfolio normally have expiration dates of from up
to eighteen months from the date written. The exercise price of a call option
may be below, equal to or above the current market value of the underlying
security at the time the option is written.

    COVERED PUT WRITING.  Each of the Portfolios that may engage in covered call
writing may engage in covered put writing. A writer of a covered put option
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. Through the writing of a put option,
the Portfolio would receive income from the premium paid by purchasers. The
potential gain on a covered put option is limited to the premium received on the
option (less the commissions paid on the transaction). At any time during the
option period, the Portfolio may be required to make payment of the exercise
price against delivery of the underlying security (or currency). A put option is
"covered" if the Portfolio maintains cash, Treasury bills or other liquid
portfolio securities with a value equal to the exercise price in a segregated
account on the Portfolio's books, or holds a put on the same security as the put
written where the exercise price of

                                       6
<PAGE>
the put held is equal to or greater than the exercise price of the put written.
The aggregate value of the obligations underlying puts may not exceed 50% of the
Portfolio's assets. The operation of and limitations on covered put options in
other respects are substantially identical to those of call options.


    PURCHASING CALL AND PUT OPTIONS.  Each of the SHORT-TERM BOND PORTFOLIO, the
CAPITAL GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH
PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO, the AGGRESSIVE EQUITY
PORTFOLIO and the INFORMATION PORTFOLIO may purchase listed and OTC call and put
options in amounts equaling up to 5% of its total assets and, in the case of
each of the QUALITY INCOME PLUS PORTFOLIO, the UTILITIES PORTFOLIO, the GLOBAL
DIVIDEND GROWTH PORTFOLIO and the STRATEGIST PORTFOLIO, up to 10% of its total
assets. Each of the last three listed Portfolios and the INFORMATION PORTFOLIO
may purchase stock index options in amounts not exceeding 5% of its total
assets. The purchase of a call option would enable a Portfolio, in return for
the premium paid, to lock in a purchase price for a security or currency during
the term of the option. The purchase of a put option would enable a Portfolio,
in return for a premium paid, to lock in a price at which it may sell a security
or currency during the term of the option.


    OPTIONS ON FOREIGN CURRENCIES.  The SHORT-TERM BOND PORTFOLIO, the GLOBAL
DIVIDEND GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH
PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO, and the AGGRESSIVE
EQUITY PORTFOLIO may purchase and write options on foreign currencies for
purposes similar to those involved with investing in forward foreign currency
exchange contracts.

    OTC OPTIONS.  OTC options are purchased from or sold (written) to dealers or
financial institutions which have entered into direct agreements with a
Portfolio. With OTC options, such variables as expiration date, exercise price
and premium will be agreed upon between a Portfolio and the transacting dealer,
without the intermediation of a third party such as the OCC. The Portfolios may
engage in OTC option transactions only with member banks of the Federal Reserve
Bank System or primary dealers in U.S. Government securities or with affiliates
of such banks or dealers.

    RISKS OF OPTIONS TRANSACTIONS.  The successful use of options depends on the
ability of the Investment Manager or, if applicable, the Sub-Advisor, to
forecast correctly interest rates, currency exchange rates and/or market
movements. If the market value of the portfolio securities (or the currencies in
which they are denominated) upon which call options have been written increases,
a Portfolio may receive a lower total return from the portion of its portfolio
upon which calls have been written than it would have had such calls not been
written. During the option period, the covered call writer has, in return for
the premium on the option, given up the opportunity for capital appreciation
above the exercise price should the market price of the underlying security (or
the value of its denominated currency) increase, but has retained the risk of
loss should the price of the underlying security (or the value of its
denominated currency) decline. The covered put writer also retains the risk of
loss should the market value of the underlying security decline below the
exercise price of the option less the premium received on the sale of the
option. In both cases, the writer has no control over the time when it may be
required to fulfill its obligation as a writer of the option. Prior to exercise
or expiration, an option position can only be terminated by entering into a
closing purchase or sale transaction. Once an option writer has received an
exercise notice, it cannot effect a closing purchase transaction in order to
terminate its obligation under the option and must deliver or receive the
underlying securities at the exercise price.

    A Portfolio's ability to close out its position as a writer of an option is
dependent upon the existence of a liquid secondary market on option exchanges.
There is no assurance that such a market will exist, particularly in the case of
OTC options.

    In the event of the bankruptcy of a broker through which a Portfolio engages
in transactions in options, the Portfolio could experience delays and/or losses
in liquidating open positions purchased or sold through the broker and/or incur
a loss of all or part of its margin deposits with the broker. In the case of OTC
options, if the transacting dealer fails to make or take delivery of the
securities underlying an option it has written, in accordance with the terms of
that option, due to insolvency or otherwise, the Portfolio would lose the
premium paid for the option as well as any anticipated benefit of the
transaction.

                                       7
<PAGE>
    Each of the exchanges has established limitations governing the maximum
number of call or put options on the same underlying security which may be
written by a single investor, whether acting alone or in concert with others
(regardless of whether such options are written on the same or different
exchanges or are held or written on one or more accounts or through one or more
brokers). An exchange may order the liquidation of positions found to be in
violation of these limits and it may impose other sanctions or restrictions.
These position limits may restrict the number of listed options which the
Portfolios may write.

    The hours of trading for options may not conform to the hours during which
the underlying securities are traded. To the extent that the option markets
close before the markets for the underlying securities, significant price and
rate movements can take place in the underlying markets that cannot be reflected
in the option markets.

    The markets in foreign currency options are relatively new and a Portfolio's
ability to establish and close out positions on such options is subject to the
maintenance of a liquid secondary market. There can be no assurance that a
liquid secondary market will exist for a particular option at any specific time.

    The value of a foreign currency option depends upon the value of the
underlying currency relative to the U.S. dollar. As a result, the price of the
option position may vary with changes in the value of either or both currencies
and have no relationship to the investment merits of a foreign security. Because
foreign currency transactions occurring in the interbank market involve
substantially larger amounts than those that may be involved in the use of
foreign currency options, investors may be disadvantaged by having to deal in an
odd lot market (generally consisting of transactions of less than $1 million)
for the underlying foreign currencies at prices that are less favorable than for
round lots.

    There is no systematic reporting of last sale information for foreign
currencies or any regulatory requirement that quotations available through
dealers or other market sources be firm or revised on a timely basis. Quotation
information available is generally representative of very large transactions in
the interbank market and thus may not reflect relatively smaller transactions
(i.e., less than $1 million) where rates may be less favorable. The interbank
market in foreign currencies is a global, around-the-clock market. To the extent
that the U.S. options markets are closed while the markets for the underlying
currencies remain open, significant price and rate movements may take place in
the underlying markets that are not reflected in the options market.


    STOCK INDEX OPTIONS.  Each of the UTILITIES PORTFOLIO, the CAPITAL GROWTH
PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO, the COMPETITIVE EDGE "BEST
IDEAS" PORTFOLIO, the AGGRESSIVE EQUITY PORTFOLIO, the INFORMATION PORTFOLIO and
the STRATEGIST PORTFOLIO may invest in options on stock indexes. Options on
stock indexes 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 less than, in the case of a
put, the exercise price of the option. This amount of cash is equal to such
difference between the closing price of the index and the exercise price of the
option expressed in dollars times a specified multiple. The writer of the option
is obligated, in return for the premium received, to make delivery of this
amount.


    RISKS OF OPTIONS ON INDEXES.  Because exercises of stock index options are
settled in cash, a Portfolio could not, if it wrote a call option, provide in
advance for its potential settlement obligations by acquiring and holding the
underlying securities. A call writer can offset some of the risk of its writing
position by holding a diversified portfolio of stocks similar to those on which
the underlying index is based. However, most investors cannot, as a practical
matter, acquire and hold a portfolio containing exactly the same stocks as the
underlying index, and, as a result, bear a risk that the value of the securities
held will vary from the value of the index. Even if an index call writer could
assemble a stock portfolio that exactly reproduced the composition of the
underlying index, the writer still would not be fully covered from a risk
standpoint because of the "timing risk" inherent in writing index options.

    When an index option is exercised, the amount of cash that the holder is
entitled to receive is determined by the difference between the exercise price
and the closing index level on the date when

                                       8
<PAGE>
the option is exercised. As with other kinds of options, the writer will not
learn that it had been assigned until the next business day, at the earliest.
The time lag between exercise and notice of assignment poses no risk for the
writer of a covered call on a specific underlying security, such as a common
stock, because there the writer's obligation is to deliver the underlying
security, not to pay its value as of a fixed time in the past. So long as the
writer already owns the underlying security, it can satisfy its settlement
obligations by simply delivering it, and the risk that its value may have
declined since the exercise date is borne by the exercising holder. In contrast,
even if the writer of an index call holds stocks that exactly match the
composition of the underlying index, it will not be able to satisfy its
assignment obligations by delivering those stocks against payment of the
exercise price. Instead, it will be required to pay cash in an amount based on
the closing index value on the exercise date; and by the time it learns that it
has been assigned, the index may have declined, with a corresponding decrease in
the value of its stock portfolio. This "timing risk" is an inherent limitation
on the ability of index call writers to cover their risk exposure by holding
stock positions.

    A holder of an index option who exercises it before the closing index value
for that day is available runs the risk that the level of the underlying index
may subsequently change. If a change causes the exercised option to fall
out-of-the-money, the exercising holder will be required to pay the difference
between the closing index value and the exercise price of the option (times the
applicable multiplier) to the assigned writer.

    If dissemination of the current level of an underlying index is interrupted,
or if trading is interrupted in stocks accounting for a substantial portion of
the value of an index, the trading of options on that index will ordinarily be
halted. If the trading of options on an underlying index is halted, an exchange
may impose restrictions prohibiting the exercise of such options.


    FUTURES CONTRACTS.  Each of the SHORT-TERM BOND PORTFOLIO, 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 COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO, the AGGRESSIVE
EQUITY PORTFOLIO, the INFORMATION PORTFOLIO and the STRATEGIST PORTFOLIO may
purchase and sell interest rate and index futures contracts that are traded on
U.S. commodity exchanges on such underlying securities as U.S. Treasury bonds,
notes, bills and GNMA Certificates and, in the case of the GLOBAL DIVIDEND
GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO,
the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the AGGRESSIVE EQUITY PORTFOLIO,
on any foreign government fixed-income security and on various currencies, and
with respect to each of the ten listed Portfolios that may engage in futures
transactions, on such indexes of U.S. (and, if applicable, foreign securities)
as may exist or come into existence.


    A futures contract purchaser 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 specified price. A seller of a futures contract incurs an
obligation to deliver the specified amount of the underlying obligation at a
specified time in return for an agreed upon price. The purchase of a futures
contract enables a Portfolio, during the term of the contract, to lock in a
price at which it may purchase a security or currency and protect against a rise
in prices pending purchase of portfolio securities. The sale of a futures
contract enables a Portfolio to lock in a price at which it may sell a security
or currency and protect against declines in the value of portfolio securities.

    Although most futures contracts call for actual delivery or acceptance of
securities, the contracts usually are closed out before the settlement date
without the making or taking of delivery. Index futures contracts provide for
the delivery of an amount of cash equal to a specified dollar amount times the
difference between the index value at the open or close of the last trading day
of the contract and the futures contract price. A futures contract sale is
closed out by effecting a futures contract purchase for the same aggregate
amount of the specific type of security (currency) and the same delivery date.
If the sale price exceeds the offsetting purchase price, the seller would be
paid the difference and would realize a gain. If the offsetting purchase price
exceeds the sale price, the seller would pay the difference and would realize a
loss. Similarly, a futures contract purchase is closed out by effecting a
futures contract sale for the same aggregate amount of the specific type of
security (currency) and the same

                                       9
<PAGE>
delivery date. If the offsetting sale price exceeds the purchase price, the
purchaser would realize a gain, whereas if the purchase price exceeds the
offsetting sale price, the purchaser would realize a loss. There is no assurance
that a Portfolio will be able to enter into a closing transaction.

    MARGIN.  If a Portfolio enters into a futures contract, it is initially
required to deposit an "initial margin" of cash or U.S. Government securities or
other liquid portfolio securities ranging from approximately 2% to 5% of the
contract amount. Initial margin requirements are established by the exchanges on
which futures contracts trade and may, from time to time, change. In addition,
brokers may establish margin deposit requirements in excess of those required by
the exchanges.

    Initial margin in futures transactions is different from margin in
securities transactions in that initial margin does not involve the borrowing of
funds by a broker's client but is, rather, a good faith deposit on the futures
contract which will be returned to the Portfolio upon the proper termination of
the futures contract. The margin deposits made are marked-to-market daily and
the Portfolio may be required to make subsequent deposits of cash or U.S.
Government securities, called "variation margin," which are reflective of price
fluctuations in the futures contract.


    OPTIONS ON FUTURES CONTRACTS.  Each of the SHORT-TERM BOND PORTFOLIO, 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 COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO, the
AGGRESSIVE EQUITY PORTFOLIO, the INFORMATION PORTFOLIO and the STRATEGIST
PORTFOLIO may purchase and write call and put options on futures contracts 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), and the writer the obligation, 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. Upon exercise of the option, the delivery of the
futures position by the writer of the option to the holder of the option is
accompanied by delivery of the accumulated balance in the writer's futures
margin account, which represents the amount by which the market price of the
futures contract at the time of exercise exceeds, in the case of a call, or is
less than, in the case of a put, the exercise price of the option on the futures
contract.


    The writer of an option on a futures contract is required to deposit initial
and variation margin pursuant to requirements similar to those applicable to
futures contracts. Premiums received from the writing of an option on a futures
contract are included in initial margin deposits.

    LIMITATIONS ON FUTURES CONTRACTS AND OPTIONS ON FUTURES.  A Portfolio may
not enter into futures contracts or purchase related options thereon if,
immediately thereafter, the amount committed to margin plus the amount paid for
premiums for unexpired options on futures contracts exceeds 5% of the value of
the Portfolio's total assets, after taking into account unrealized gains and
unrealized losses on such contracts into which it has entered; provided,
however, that in the case of an option that is in-the-money (the exercise price
of the call (put) option is less (more) than the market price of the underlying
security) at the time of purchase, the in-the-money amount may be excluded in
calculating the 5%. However, there is no overall limitation on the percentage of
a Portfolio's net assets which may be subject to a hedge position.

    RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS.  The prices
of securities and indexes subject to futures contracts (and thereby the futures
contract prices) may correlate imperfectly with the behavior of the cash prices
of the Portfolio's securities (and the currencies in which they are
denominated). Also, prices of futures contracts may not move in tandem with the
changes in prevailing interest rates, market movements and/or currency exchange
rates against which a Portfolio seeks a hedge. A correlation may also be
distorted (a) temporarily, by short-term traders' seeking to profit from the
difference between a contract or security price objective and their cost of
borrowed funds; (b) by investors in futures contracts electing to close out
their contracts through offsetting transactions rather than meet margin deposit
requirements; (c) by investors in futures contracts opting to make or take
delivery of underlying securities rather than engage in closing transactions,
thereby reducing liquidity of the futures market; and (d) temporarily, by
speculators who view the deposit requirements in the futures markets as less
onerous than margin requirements in the cash market. Due to the possibility of
price

                                       10
<PAGE>
distortion in the futures market and because of the possible imperfect
correlation between movements in the prices of securities and movements in the
prices of futures contracts, a correct forecast of interest rate, currency
exchange rate and/or market movement trends by the Investment Manager (and/or if
applicable, the Sub-Advisor) may still not result in a successful hedging
transaction.

    There is no assurance that a liquid secondary market will exist for futures
contracts and related options in which a Portfolio may invest. In the event a
liquid market does not exist, it may not be possible to close out a futures
position and, in the event of adverse price movements, the Portfolio would
continue to be required to make daily cash payments of variation margin. The
absence of a liquid market in futures contracts might cause the Portfolio to
make or take delivery of the underlying securities (currencies) at a time when
it may be disadvantageous to do so.

    Exchanges also 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. In the event of adverse price movements, a Portfolio
would continue to be required to make daily cash payments of variation margin on
open futures positions. In these situations, if the Portfolio has insufficient
cash, it may have to sell portfolio securities to meet daily variation margin
requirements at a time when it may be disadvantageous to do so. In addition, the
Portfolio may be required to take or make delivery of the instruments underlying
interest rate futures contracts it holds at a time when it is disadvantageous to
do so. The inability to close out options and futures positions could also have
an adverse impact on a Portfolio's ability to effectively hedge its portfolio.

    Futures contracts and options thereon which are purchased or sold on foreign
commodities exchanges may have greater price volatility than their U.S.
counterparts. Furthermore, foreign commodities exchanges may be less regulated
and under less governmental scrutiny than U.S. exchanges. Brokerage commissions,
clearing costs and other transaction costs may be higher on foreign exchanges.
Greater margin requirements may limit a Portfolio's ability to enter into
certain commodity transactions on foreign exchanges. Moreover, differences in
clearance and delivery requirements on foreign exchanges may occasion delays in
the settlement of a Portfolio's transactions effected on foreign exchanges.

    In the event of the bankruptcy of a broker through which a Portfolio engages
in transactions in futures or options thereon, the Portfolio could experience
delays and/or losses in liquidating open positions purchased or sold through the
broker and/or incur a loss of all or part of its margin deposits with the
broker.

    If a Portfolio maintains a short position in a futures contract or has sold
a call option in a futures contract, it will cover this position by holding, in
a segregated account maintained on the books of the Portfolio, cash, U.S.
government securities or other liquid portfolio securities equal in value (when
added to any initial or variation margin on deposit) to the market value of the
securities underlying the futures contract or the exercise price of the option.
Such a position may also be covered by owning the securities underlying the
futures contract (in the case of a stock index futures contract a portfolio of
securities substantially replicating the relevant index), or by holding a call
option permitting the Portfolio to purchase the same contract at a price no
higher than the price at which the short position was established.

    In addition, if a Portfolio holds a long position in a futures contract or
has sold a put option on a futures contract, it will hold cash, U.S. government
securities or other liquid portfolio securities equal to the purchase price of
the contract or the exercise price of the put option (less the amount of initial
or variation margin on deposit) in a segregated account maintained on the books
of the Portfolio. Alternatively, the Portfolio could cover its long position by
purchasing a put option on the same futures contract with an exercise price as
high or higher than the price of the contract held by the Portfolio.

ADDITIONAL INFORMATION CONCERNING THE QUALITY INCOME PLUS AND SHORT-TERM BOND
PORTFOLIOS

    COLLATERALIZED MORTGAGE OBLIGATIONS.  The Portfolio(s) may invest in CMOs -
collateralized mortgage obligations. CMOs are debt obligations collateralized by
mortgage loans or mortgage pass-

                                       11
<PAGE>
through securities (collectively "Mortgage Assets"). Payments of principal and
interest on the Mortgage Assets and any reinvestment income are used to make
payments on the CMOs. CMOs are issued in multiple classes. Each class has a
specific fixed or floating coupon rate and a stated maturity or final
distribution date. The principal and interest on the Mortgage Assets may be
allocated among the classes in a number of different ways. Certain classes will,
as a result of the collection, have more predictable cash flows than others. As
a general matter, the more predictable the cash flow, the lower the yield
relative to other Mortgage Assets. The less predictable the cash flow, the
higher the yield and the greater the risk. The Portfolio(s) may invest in any
class of CMO.

    Certain mortgage-backed securities in which the Portfolio(s) may invest
(E.G.,certain classes of CMOs) may increase or decrease in value substantially
with changes in interest rates and/or the rates of prepayment. In addition, if
the collateral securing CMOs or any third party guarantees are insufficient to
make payments, the Portfolio could sustain a loss.

    In addition, the SHORT-TERM BOND PORTFOLIO may invest up to 15% of its net
assets in stripped mortgage-backed securities, which are usually structured in
two classes. One class entitles the holder to receive all or most of the
interest but little or none of the principal of a pool of Mortgage Assets (the
interest-only or "IO Class"), while the other class entitles the holder to
receive all or most of the principal but little or none of the interest (the
principal-only or "PO" Class). IOs tend to decrease in value substantially if
interest rates decline and prepayment rates become more rapid. POs tend to
decrease in value substantially if interest rates increase and the rate of
repayment decreases.

    The SHORT-TERM BOND PORTFOLIO may invest up to 10% of its assets in inverse
floaters. An inverse floater has a coupon rate that moves in the direction
opposite to that of a designated interest rate index. Like most other fixed
income securities, the value of inverse floaters will decrease as interest rates
increase. They are more volatile, however, than most other fixed income
securities because the coupon rate on an inverse floater typically changes at a
multiple of the change in the relevant index rate. Thus, any rise in the index
rate (as a consequence of an increase in interest rates) causes a
correspondingly greater drop in the coupon rate of an inverse floater while a
drop in the index rate causes a correspondingly greater increase in the coupon
of an inverse floater. Some inverse floaters may also increase or decrease
substantially because of changes in the rate of prepayments.

    ASSET-BACKED SECURITIES.  The securitization techniques used to develop
mortgage-backed securities are also applied to a broad range of other assets.
Various types of assets, primarily automobile and credit card receivables and
home equity loans, are being securitized in pass-through structures similar to
the mortgage pass-through structures. These types of securities are known as
asset-backed securities. The Portfolio(s) may invest in any type of asset-backed
security.

    Asset-backed securities have risk characteristics similar to mortgage-backed
securities. Like mortgage-backed securities, they generally decrease in value as
a result of interest rate increases, but may benefit less than other
fixed-income securities from declining interest rates, principally because of
prepayments. Also, as in the case of mortgage-backed securities, prepayments
generally increase during a period of declining interest rates although other
factors, such as changes in credit use and payment patterns, may also influence
prepayment rates. Asset-backed securities also involve the risk that various
federal and state consumer laws and other legal and economic factors may result
in the collateral backing the securities being insufficient to support payment
on the securities.

    ADDITIONAL INFORMATION CONCERNING THE SHORT-TERM BOND PORTFOLIO.  The
SHORT-TERM BOND PORTFOLIO'S investments in preferred stocks are limited to those
rated in one of 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 IBCA, Inc.
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 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.

(including lost profits), even if notified of the possibility of such damages.


    MONEY MARKET SECURITIES.  In addition to the short-term fixed-income
securities in which the Portfolios may otherwise invest, the Portfolios may
invest in various money market securities for cash management purposes or when
assuming a temporary defensive position, which among others may include
commercial paper, bank acceptances, bank obligations, corporate debt securities,
certificates of deposit, U.S. Government securities, obligations of savings
institutions and repurchase agreements. (This section does not apply to the
MONEY MARKET PORTFOLIO whose money market instruments are described in the
Prospectus.) Such securities are limited to:

    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, including Treasury bills, notes and bonds;

    BANK OBLIGATIONS.  Obligations (including certificates of deposit, time
deposits 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;

    OBLIGATIONS OF SAVINGS INSTITUTIONS.  Certificates of deposit of savings
banks and savings and loan association, 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 federally insured by the Bank Insurance
Fund or the Savings Association Insurance Fund (each of which is administered by
the FDIC), limited to $100,000 principal amount per certificate and to 10% or
less of a 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 two highest grades by Moody's
Investors Service, Inc. ("Moody's") or, if not

                                       13
<PAGE>
rated, issued by a company having an outstanding debt issue rated at least AA by
S&P or Aa by Moody's; and

    REPURCHASE AGREEMENTS.  Each Portfolio may invest in repurchase agreements.
When cash may be available for only a few days, it may be invested by a
Portfolio in repurchase agreements until such time as it may otherwise be
invested or used for payments of obligations of the Portfolio. These agreements,
which may be viewed as a type of secured lending by the Portfolio, 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
serving as 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 collateral will
be marked-to-market daily to determine that the value of the collateral, as
specified in the agreement, does not decrease below the purchase price plus
accrued interest. If such decrease occurs, additional collateral will be
requested and, when received, added to the account to maintain full
collateralization. The Portfolio will accrue interest from the institution until
the time when the repurchase is to occur. Although this 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.

    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Portfolio follows procedures designed to
minimize such risks. These procedures include effecting repurchase transactions
only with large, well-capitalized and well-established financial institutions
whose financial condition will be continually monitored by the Investment
Manager subject to procedures established by the Trustees. In addition, as
described above, the value of the collateral underlying the repurchase agreement
will be at least equal to the repurchase price, including any accrued interest
earned on the repurchase agreement. In the case of the MONEY MARKET PORTFOLIO,
such collateral will consist entirely of securities that are direct obligations
of, or that are fully guaranteed as to principal and interest by, the United
States or any agency thereof, and/or certificates of deposit, bankers'
acceptances which are eligible for acceptance by a Federal Reserve Bank, and, if
the seller is a bank, mortgage related securities (as such term is defined in
section 3(a)(41) of the Securities Exchange Act of 1934) that at the time the
repurchase agreement is entered into are rated in the highest rating category by
the "Requisite NRSROs" (as defined in Rule 2a-7 under the Investment Company Act
of 1940). Additionally, in the case of the MONEY MARKET PORTFOLIO, the
collateral must qualify the repurchase agreement for preferential treatment
under the Federal Deposit Insurance Act of the Federal Bankruptcy Code. In the
event of a default or bankruptcy by a selling financial institution, the
Portfolio will seek to liquidate such collateral. However, the exercising of the
Portfolio's right to liquidate such collateral could involve certain costs or
delays and, to the extent that proceeds from any sale upon a default of the
obligation to repurchase were less than the repurchase price, the Portfolio
could suffer a loss. It is the current policy of each Portfolio not to invest in
repurchase agreements that do not mature within seven days if any such
investment, together with any other illiquid assets held by the Portfolio,
amounts to more than 10% of its net assets in the case of each of the MONEY
MARKET PORTFOLIO, the QUALITY INCOME PLUS PORTFOLIO, the UTILITIES PORTFOLIO,
the DIVIDEND GROWTH PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the EUROPEAN GROWTH
PORTFOLIO, the EQUITY PORTFOLIO and the STRATEGIST PORTFOLIO and 15% of its net
assets in the case of each of the other Portfolios.

    REVERSE REPURCHASE AGREEMENTS AND DOLLAR ROLLS.  Each of the SHORT-TERM BOND
PORTFOLIO, the QUALITY INCOME PLUS PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO and
the PACIFIC GROWTH PORTFOLIO and may use reverse repurchase agreements for
purposes of meeting redemptions or as part of its investment strategy. The
SHORT-TERM BOND PORTFOLIO may also use dollar rolls as part of its investment
strategy.

    Reverse repurchase agreements involve sales by the Portfolio of assets
concurrently with an agreement by the Portfolio to repurchase the same assets at
a later date at a fixed price. Reverse repurchase agreements involve the risk
that the market value of the securities the Portfolio is obligated to purchase
under the agreement may decline below the repurchase price. In the event the
buyer of securities under a reverse repurchase agreement files for bankruptcy or
becomes insolvent, the Portfolio's use of the

                                       14
<PAGE>
proceeds of the agreement may be restricted pending a determination by the other
party, or its trustee or receiver, whether to enforce the Portfolio's obligation
to repurchase the securities.

    Dollar rolls involve the Portfolio selling securities for delivery in the
current month and simultaneously contracting to repurchase substantially similar
(same type and coupon) securities on a specified future date. During the roll
period, the Portfolio will forgo principal and interest paid on the securities.
The Portfolio is compensated by the difference between the current sales price
and the lower forward price for the future purchase (often referred to as the
"drop") as well as by the interest earned on the cash proceeds of the initial
sale.

    Reverse repurchase agreements and dollar rolls are speculative techniques
involving leverage and are considered borrowings by the Portfolio. With respect
to each of the QUALITY INCOME PLUS PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO and
the PACIFIC GROWTH PORTFOLIO, reverse repurchase agreements may not exceed 10%
of the Portfolio's total assets.

    INVESTMENT IN 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 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 a Portfolio to invest in the real estate industry
(the Fund is prohibited from investing in real estate directly). As a
shareholder in a real estate investment trust, a 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.

    LENDING PORTFOLIO SECURITIES.  Each Portfolio may lend its portfolio
securities to brokers, dealers and other financial institutions, provided that
the loans are callable at any time by the Portfolio, and are at all times
secured by cash or cash equivalents, which are maintained in a segregated
account pursuant to applicable regulations and that are equal to at least 100%
of the market value, determined daily, of the loaned securities. The advantage
of these loans is that the Portfolio continues to receive the income on the
loaned securities while at the same time earning interest on the cash amounts
deposited as collateral, which will be invested in short-term obligations. A
Portfolio will not lend securities with a value exceeding 10% of the Portfolio's
total assets.

    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, these loans of portfolio securities will
only be made to firms deemed by the Portfolio's management to be creditworthy
and when the income which can be earned from such loans justifies the attendant
risks. Upon termination of the loan, the borrower is required to return the
securities to the Portfolio. Any gain or loss in the market price during the
loan period would inure to the Portfolio.

    When voting or consent rights which accompany loaned securities pass to the
borrower, a Portfolio will follow the policy of calling the loaned securities,
to be delivered within one day after notice, to permit the exercise of the
rights if the matters involved would have a material effect on the Portfolio's
investment in the loaned securities. The Portfolio will pay reasonable finder's,
administrative and custodial fees in connection with a loan of its securities.

    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS.  From
time to time, each Portfolio 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 these 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 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, the Portfolio may sell the securities

                                       15
<PAGE>
before the settlement date, if it is deemed advisable. The securities so
purchased or sold are subject to market fluctuation and no interest or dividends
accrue to the purchaser prior to the settlement date.

    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. 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 its
net asset value. The Portfolio will also establish a segregated account on its
books in which it will continually maintain cash or cash equivalents or other
liquid portfolio securities equal in value to commitments to purchase securities
on a when-issued, delayed delivery or forward commitment basis.

    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 a Portfolio until the Portfolio determines that issuance of the
security is probable. At that time, the Portfolio will record the transaction
and, in determining its net asset value, will reflect the value of the security
daily. At that time, the Portfolio will also establish a segregated account on
the Portfolio's books in which it will maintain cash or cash equivalents or
other liquid portfolio securities equal in value to recognized commitments for
such securities.

    The value of a Portfolio's commitments to purchase the securities of any one
issuer, together with the value of all securities of such issuer owned by the
Portfolio, may not exceed 5% of the value of the Portfolio's total assets at the
time the initial commitment to purchase such securities is made. An increase in
the percentage of the Portfolio assets committed to the purchase of securities
on a "when, as and if issued" basis may increase the volatility of its net asset
value. A Portfolio may also sell securities on a "when, as and if issued" basis
provided that the issuance of the security will result automatically from the
exchange or conversion of a security owned by the Portfolio at the time of sale.

    PRIVATE PLACEMENTS.  As a fundamental policy, which may only be changed 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 (the "SECURITIES ACT"), or which are otherwise
not readily marketable.


    As a non-fundamental policy, which may be changed by the Trustees, each of
the UTILITIES PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the INCOME BUILDER
PORTFOLIO and the EUROPEAN GROWTH PORTFOLIO may invest up to 10% of its total
assets in such restricted securities; each of the HIGH YIELD PORTFOLIO, the
PACIFIC GROWTH PORTFOLIO, the GLOBAL DIVIDEND GROWTH PORTFOLIO and the
COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO may invest up to 15% of its total assets
in such restricted securities; and each of the SHORT-TERM BOND PORTFOLIO, the
AGGRESSIVE EQUITY PORTFOLIO and the INFORMATION PORTFOLIO may invest up to 15%
of its net assets in such restricted securities. (With respect to these eleven
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.)
Limitations on the resale of these securities may have an adverse effect on
their marketability, and may prevent a Portfolio from disposing of them promptly
at reasonable prices. A Portfolio may have to bear the expense of registering
the securities for resale and the risk of substantial delays in effecting the
registration.


    Rule 144A permits the above-listed Portfolios to sell restricted securities
to qualified institutional buyers without limitation. The Investment Manager,
pursuant to procedures adopted by the Trustees, will make a determination as to
the liquidity of each restricted security purchased by a Portfolio. If a
restricted security is determined to be "liquid," the security will not be
included within the category "illiquid securities," which may not exceed, as to
each of the QUALITY INCOME PLUS PORTFOLIO, the UTILITIES PORTFOLIO, the DIVIDEND
GROWTH PORTFOLIO, the CAPITAL GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO,
the EQUITY

                                       16
<PAGE>
PORTFOLIO and the STRATEGIST PORTFOLIO, 10% of the Portfolio's total assets and
as to each of the other Portfolios listed above, 15% of the Portfolio's net
assets, as more fully described under "Fund Policies/ Investment Restrictions"
below. However, investing in Rule 144A securities could have the effect of
increasing the level of Portfolio illiquidity to the extent the Portfolio, at a
particular point in time, may be unable to find qualified institutional buyers
interested in purchasing such securities.


    WARRANTS AND SUBSCRIPTION RIGHTS.  The Portfolios, other than the MONEY
MARKET PORTFOLIO and the QUALITY INCOME PLUS PORTFOLIO, may acquire warrants and
subscription rights 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 EQUITY PORTFOLIO, the INFORMATION PORTFOLIO and the STRATEGIST PORTFOLIO may
invest up to 5% of its assets in warrants not attached to other securities with
a limit of up to 2 % of its total assets in warrants that are not listed on the
New York or American Stock Exchange. 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. A warrant is, in effect, an option to purchase
equity securities at a specific price, generally valid for a specific period of
time, and has no voting rights, pays no dividends and has no rights with respect
to the corporation issuing it.


    A subscription right is a privilege granted to existing shareholders of a
corporation to subscribe to shares of a new issue of common stock before it is
offered to the public. A subscription right normally has a life of two to four
weeks and a subscription price lower than the current market value of the common
stock.


    OTHER INVESTMENT VEHICLES.  Each of the GLOBAL DIVIDEND GROWTH PORTFOLIO,
the EUROPEAN GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO and the INFORMATION
PORTFOLIO may acquire shares in other investment companies, including foreign
investment companies. Investment in foreign investment companies may be the sole
or most practical means by which these four Portfolios may participate in
certain foreign securities markets. As a shareholder in an investment company, a
Portfolio would bear its ratable share of that entity'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 other investment companies.



D. FUND POLICIES/INVESTMENT RESTRICTIONS


    The investment restrictions listed below have been adopted by the Fund as
fundamental policies of the Portfolios. Under the Investment Company Act of 1940
(the "INVESTMENT COMPANY ACT"), a fundamental policy of a Portfolio may not be
changed without the vote of a majority of the outstanding voting securities of
the Portfolio. The Investment Company Act defines a majority as the lesser of
(a) 67% or more of the shares of a Portfolio present at a meeting of Fund
shareholders, if the holders of 50% of the outstanding shares of the Portfolio

of any one issuer (other than obligations issued or guaranteed by the United
States Government, its agencies or instrumentalities), or purchase more than 10%

issuer (for this purpose all outstanding debt securities of an issuer are

SHORT-TERM BOND PORTFOLIO)), 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

objectives and policies; (b) by investing in repurchase agreements; or (c) by
lending its portfolio securities, not in excess of 10% of the value of a

reason of: (a) entering into any repurchase agreement (or, in the case of the

E. PORTFOLIO TURNOVER

    For the fiscal years ended December 31, 1998 and 1999, the portfolio
turnover rates of the Capital Growth Portfolio were 248% and 575.04%,
respectively. These variations resulted form the portfolio manager's responses
to varying market conditions during these periods.

III. MANAGEMENT OF THE FUND
--------------------------------------------------------------------------------

A. BOARD OF TRUSTEES

    The Trustees oversee the management of the Portfolios but do not manage each
Portfolio. The Trustees review various services provided by or under the
direction of the Investment Manager to ensure that each Portfolio's general
investment policies and programs are properly carried out. The Trustees also
conduct their review to ensure that administrative services are provided to each
Portfolio in a satisfactory manner.

    Under state law, the duties of the Trustees are generally characterized as a
duty of loyalty and a duty of care. The duty of loyalty requires a Trustee to
exercise his or her powers in the interest of the Fund and each Portfolio and
not the Trustee's own interest or the interest of another person or
organization. A Trustee satisfies his or her duty of care by acting in good
faith with the care of an ordinarily prudent person and in a manner the Trustee
reasonably believes to be in the best interest of the Fund and each Portfolio
and its shareholders.

B. MANAGEMENT INFORMATION


    TRUSTEES AND OFFICERS.  The Board of the Fund consists of nine
(9) Trustees. These same individuals also serve as directors or trustees for all
of the Morgan Stanley Dean Witter Funds. Six Trustees (67% of the total number)
have no affiliation or business connection with the Investment Manager or any of
its affiliated persons and do not own any stock or other securities issued by
the Investment Manager's parent company, MSDW. These are the "non-interested" or
"independent" Trustees. The other three Trustees (the "MANAGEMENT TRUSTEES") are
affiliated with the Investment Manager.



    The Trustees and executive officers of the Fund, their principal business
occupations during the last five years and their affiliations, if any, with the
Investment Manager, and with the Morgan Stanley Dean Witter Funds (there were 93
such Funds as of the calendar year ended December 31, 1999), are shown below.

Vice President and Assistant General Counsel of the Investment Manager and MSDW
Services Company, are Assistant Secretaries of the Fund.

    INDEPENDENT DIRECTORS/TRUSTEES AND THE COMMITTEES.  Law and regulation
establish both general guidelines and specific duties for the independent
directors/trustees. The Morgan Stanley Dean Witter Funds seek as independent
directors/trustees individuals of distinction and experience in business and
finance, government service or academia; these are people whose advice and
counsel are in demand by others and for whom there is often competition. To
accept a position on the Funds' boards, such individuals may reject other
attractive assignments because the Funds make substantial demands on their time.
All of the independent directors/trustees serve as members of the Audit
Committee. In addition, three of the directors/trustees, including two
independent directors/trustees, serve as members of the Derivatives Committee
and the Insurance Committee.

    The independent directors/trustees are charged with recommending to the full
board approval of management, advisory and administration contracts, Rule 12b-1
plans and distribution and underwriting agreements; continually reviewing
Portfolio performance; checking on the pricing of portfolio securities,
brokerage commissions, transfer agent costs and performance, and trading among
Funds in the same

                                       25
<PAGE>
complex; and approving fidelity bond and related insurance coverage and
allocations, as well as other matters that arise from time to time. The
independent directors/trustees are required to select and nominate individuals
to fill any independent director/trustee vacancy on the board of any Fund that
has a Rule 12b-1 plan of distribution. Most of the Morgan Stanley Dean Witter
Funds have a Rule 12b-1 plan.

    The Audit Committee is charged with recommending to the full board the
engagement or discharge of the Fund's independent accountants; directing
investigations into matters within the scope of the independent accountants'
duties, including the power to retain outside specialists; reviewing with the
independent accountants the audit plan and results of the auditing engagement;
approving professional services provided by the independent accountants and
other accounting firms prior to the performance of the services; reviewing the
independence of the independent accountants; considering the range of audit and
non-audit fees; reviewing the adequacy of the Fund's system of internal
controls; and preparing and submitting Committee meeting minutes to the full
board.

    The board of each Fund has a Derivatives Committee to approve parameters for
and monitor the activities of the Fund with respect to derivative investments,
if any, made by the Portfolios.

    Finally, the board of each Fund has formed an Insurance Committee to review
and monitor the insurance coverage maintained by the Fund.

    ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT DIRECTORS/TRUSTEES FOR
ALL MORGAN STANLEY DEAN WITTER FUNDS.  The independent directors/trustees and
the Funds' management believe that having the same independent
directors/trustees for each of the Morgan Stanley Dean Witter Funds avoids the
duplication of effort that would arise from having different groups of
individuals serving as independent directors/trustees for each of the Funds or
even of sub-groups of Funds. They believe that having the same individuals serve
as independent directors/trustees of all the Funds tends to increase their
knowledge and expertise regarding matters which affect the Fund complex
generally and enhances their ability to negotiate on behalf of each Fund with
the Fund's service providers. This arrangement also precludes the possibility of
separate groups of independent directors/trustees arriving at conflicting
decisions regarding operations and management of the Funds and avoids the cost
and confusion that would likely ensue. Finally, having the same independent
directors/trustees serve on all Fund boards enhances the ability of each Fund to
obtain, at modest cost to each separate Fund, the services of independent
directors/trustees, of the caliber, experience and business acumen of the
individuals who serve as independent directors/trustees of the Morgan Stanley
Dean Witter Funds.

    TRUSTEE AND OFFICER INDEMNIFICATION.  The Fund's Declaration of Trust
provides that no Trustee, officer, employee or agent of the Fund is liable to
the Fund or to a shareholder, nor is any Trustee, officer, employee or agent
liable to any third persons in connection with the affairs of the Fund, except
as such liability may arise from his/her or its own bad faith, willful
misfeasance, gross negligence or reckless disregard of his/her or its duties. It
also provides that all third persons shall look solely to the Fund property for
satisfaction of claims arising in connection with the affairs of the Fund. With
the exceptions stated, the Declaration of Trust provides that a Trustee,
officer, employee or agent is entitled to be indemnified against all liability
in connection with the affairs of the Fund.

C. COMPENSATION

    The Fund pays each Independent Trustee an annual fee of $800 plus a per
meeting fee of $50 for meetings of the Board of Trustees, the Independent
Trustees or Committees of the Board of Trustees attended by the Trustee (the
Fund pays the Chairman of the Audit Committee an additional annual fee of $750
and the Chairmen of the Derivatives and Insurance Committees additional annual
fees of $500). If a Board meeting and a meeting of the Independent Trustees or a
Committee meeting, or a meeting of the Independent Trustees and/or more than one
Committee meeting, take place on a single day, the Trustees are paid a single
meeting fee by the Fund. The Fund also reimburses such Trustees for travel and
other out-of-pocket expenses incurred by them in connection with attending such
meetings. Trustees and officers of the Fund who are or have been employed by the
Investment Manager or an affiliated company receive no compensation or expense
reimbursement from the Fund for their services as Trustee.

    As of the date of this STATEMENT OF ADDITIONAL INFORMATION, 55 of the Morgan
Stanley Dean Witter Funds, including the Fund, have adopted a retirement program
under which an independent director/ trustee who retires after serving for at
least five years (or such lesser period as may be determined by the Board) as an
independent director/trustee of any Morgan Stanley Dean Witter Fund that has
adopted the retirement program (each such Fund referred to as an "ADOPTING FUND"
and each such independent director/trustee referred to as an "ELIGIBLE TRUSTEE")
is entitled to retirement payments upon reaching the eligible retirement age
(normally, after attaining age 72). Annual payments are based upon length of
service.

    Currently, upon retirement, each Eligible Trustee is entitled to receive
from the Adopting Fund, commencing as of his or her retirement date and
continuing for the remainder of his or her life, an annual retirement benefit
(the "REGULAR BENEFIT") equal to 30.22% of his or her Eligible Compensation plus
0.5036667% of such Eligible Compensation for each full month of service as an
independent director/ trustee of any Adopting Fund in excess of five years up to
a maximum of 60.44% after ten years of service. The foregoing percentages may be
changed by the Board.(1) "ELIGIBLE COMPENSATION" is one-fifth of the total
compensation earned by such Eligible Trustee for service to the Adopting Fund in
the five year period prior to the date of the Eligible Trustee's retirement.
Benefits under the retirement program are accrued as expenses on the books of
the Adopting Funds. Such benefits are not secured or funded by the Adopting
Funds.

    The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended December 31,
1999 and by the 55 Morgan Stanley Dean Witter Funds (including the Fund) for the
year ended December 31, 1999, and the estimated retirement benefits for the
Independent Trustees, to commence upon their retirement, from the Fund as of
December 31, 1999 and from the 55 Morgan Stanley Dean Witter Funds as of
December 31, 1999.

    benefits based upon the combined life expectancy of the Eligible Trustee and
    his or her spouse on the date of such Eligible Trustee's retirement. In
    addition, the Eligible Trustee may elect that the surviving spouse's
    periodic payment of benefits will be equal to a lower percentage of the
    periodic amount, when both spouses were alive. The amount estimated to be
    payable under this method, through the remainder of the later of the lives
    of the Eligible Trustee and spouse, will be the actuarial equivalent of the
    Regular Benefit.

    varies depending on the Eligible Trustee's elections described in Footnote
    (1) above.

</TABLE>



    The INFORMATION PORTFOLIO had not commenced operations prior to the date of
this STATEMENT OF ADDITIONAL INFORMATION.


    The Investment Manager has retained its wholly-owned subsidiary, MSDW
Services Company, to perform administrative services for the Fund.

    Under a Sub-Advisory Agreement (the "SUB-ADVISORY AGREEMENT") between the
Sub-Advisor and the Investment Manager respecting the EUROPEAN GROWTH PORTFOLIO
and the PACIFIC GROWTH PORTFOLIO, the Sub-Advisor provides these Portfolios with
investment advice and portfolio management, subject to the overall supervision
of the Investment Manager. The Investment Manager pays the Sub-Advisor monthly
compensation equal to 40% of the Investment Manager's fee, payable in respect of
the EUROPEAN GROWTH PORTFOLIO and the PACIFIC GROWTH PORTFOLIO.

B. PRINCIPAL UNDERWRITER

    The Fund's principal underwriter is the Distributor (which has the same
address as the Investment Manager). In this capacity, each Portfolio's shares
are distributed by the Distributor. The Distributor, a Delaware corporation, is
a wholly-owned subsidiary of MSDW.

    The Fund and the Distributor have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act. Under the
Distribution Agreement, the Distributor uses its best efforts in rendering
services to the Fund, but in the absence of willful misfeasance, bad faith,
gross negligence or reckless disregard of its obligations, the Distributor is
not liable to the Fund or any of its shareholders for any error of judgment or
mistake of law or for any act or omission or for any losses sustained by the
Portfolios or their shareholders.

C. SERVICES PROVIDED BY THE INVESTMENT MANAGER AND SUB-ADVISOR

    Each Portfolio has retained the Investment Manager to provide administrative
services, manage its business affairs and (except for the PACIFIC GROWTH
PORTFOLIO and the EUROPEAN GROWTH PORTFOLIO) invest its assets, including the
placing of orders for the purchase and sale of portfolio securities. Each of the
PACIFIC GROWTH PORTFOLIO and the EUROPEAN GROWTH PORTFOLIO has retained the
Investment Manager to supervise the investment of its assets.

                                       30
<PAGE>
    Under the terms of the Management Agreement, the Investment Manager also
maintains certain of the Fund's books and records and furnishes, at its own
expense, the office space, facilities, equipment, clerical help, bookkeeping and
certain legal services as the Fund may reasonably require in the conduct of its
business, including the preparation of prospectuses, proxy statements and
reports required to be filed with federal and state securities commissions
(except insofar as the participation or assistance of independent accountants
and attorneys is, in the opinion of the Investment Manager, necessary or
desirable). In addition, the Investment Manager pays the salaries of all
personnel, including officers of the Fund, who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone service, heat,
light, power and other utilities provided to the Fund.

    The services provided by the Sub-Advisor are discussed above under
"Investment Manager and Sub-Advisor."

    Expenses not expressly assumed by the Investment Manager under the
Management Agreement, by the Sub-Advisor for the EUROPEAN GROWTH PORTFOLIO and
the PACIFIC GROWTH PORTFOLIO under the Sub-Advisory Agreement, or by the
Distributor, will be paid by the Portfolios. Each Portfolio pays all expenses
incurred in its operation and a portion of the Fund's general administration
expenses allocated based on the asset sizes of the Portfolios. The Portfolios'
direct expenses include, but are not limited to: expenses of the Plan of
Distribution pursuant to Rule 12b-1; charges and expenses of any registrar,
custodian, transfer and dividend disbursing agent; brokerage commissions;
certain taxes; registration costs of the Fund under federal and state securities
laws; shareholder servicing costs, charges and expenses of any outside service
used for pricing of the Portfolios' shares; fees and expenses of legal counsel,
including counsel to the Trustees who are not interested persons of the Fund or
of the Investment Manager (or the Sub-Advisor) (not including compensation or
expenses of attorneys who are employees of the Investment Manager (or the
Sub-Advisor)); fees and expenses of the Fund's independent accountants; interest
on Portfolio borrowings; and all other expenses attributable to a particular
Portfolio. The 12b-1 fees relating to Class Y will be allocated directly to
Class Y. In addition, other expenses associated with a particular Class (except
advisory or custodial fees) may be allocated directly to that Class, provided
that such expenses are reasonably identified as specifically attributable to
that Class and the direct allocation to that Class is approved by the Trustees.

    Expenses which are allocated on the basis of size of the respective
Portfolios include the costs and expenses of printing, including typesetting,
and distributing prospectuses and statements of additional information of the
Fund and supplements thereto to the Fund's shareholders; all expenses of
shareholders' and Trustees' meetings and of preparing, printing and mailing
proxy statements and reports to shareholders; fees and travel expenses of
Trustees or members of any advisory board or committee who are not employees of
the Investment Manager (or the Sub-Advisor) or any corporate affiliate of the
Investment Manager (or the Sub-Advisor); state franchise taxes; Securities and
Exchange Commission fees; membership dues of industry associations; postage;
insurance premiums on property or personnel (including officers and Trustees) of
the Fund which inure to its benefit; and all other costs of the Fund's
operations properly payable by the Fund and allocable on the basis of size to
the respective Portfolios. Depending on the nature of a legal claim, liability
or lawsuit, litigation costs, payment of legal claims or liabilities and any
indemnification relating thereto may be directly applicable to the Portfolio or
allocated on the basis of the size of the respective Portfolios. The Trustees
have determined that this is an appropriate method of allocation of expenses.

    Each of the Management Agreement and the Sub-Advisory Agreement provides
that in the absence of willful misfeasance, bad faith, gross negligence or
reckless disregard of its obligations thereunder, the Investment Manager and the
Sub-Advisor, respectively, are not liable to the Fund or any of its investors
(and, in the case of the Sub-Advisory Agreement, to the Investment Manager) for
any act or omission or for any losses sustained by the Fund or its investors.

    Each of the Management Agreement and the Sub-Advisory Agreement will remain
in effect from year to year provided continuance of the applicable Agreement is
approved at least annually by the vote of the holders of a majority, as defined
in the Investment Company Act, of the outstanding shares of each

                                       31
<PAGE>
affected Portfolio, or by the Trustees; provided that in either event such
continuance is approved annually by the vote of a majority of the Trustees,
including a majority of the Independent Trustees.

D. RULE 12b-1 PLAN

    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Investment Company Act (the "Plan"). Under the Plan, Class Y shares of each
Portfolio bear a distribution fee paid to the Distributor which is accrued daily
and payable monthly at the annual rate of 0.25% of the average daily net assets
of the Class.

    The Plan provides that each Portfolio's distribution fee shall compensate
the Distributor, Dean Witter Reynolds and its affiliates, and other selected
broker-dealers for expenses they incur in connection with the distribution of
the Portfolio's Class Y shares. These expenses may include: (i) cost incurred in
providing personal services to shareholders; (ii) overhead and other branch
office distribution-related expenses including, but not limited to, expenses of
operating the Distributor's or other broker-dealers' offices used for selling
Portfolio shares (E.G., lease and utility costs, salaries and employee benefits
of operations and sales support personnel, costs related to client sales
seminars and telephone expenses); (iii) printing and mailing costs relating to
prospectuses and reports (for new shareholders); and (iv) costs incurred in
connection with advertising materials and sales literature.

    Under the Plan, the Distributor provides the Fund, for review by the
Trustees, and the Trustees review, promptly after the end of each calendar
quarter, a written report regarding the distribution expenses incurred on behalf
of each Portfolio during such calendar quarter, which report includes (1) an
itemization of the types of expenses and the purposes therefor; (2) the amounts
of such expenses; and (3) a description of the benefits derived by the Fund.

    On an annual basis, the Trustees, including a majority of the Independent
Trustees, consider whether the Plan should be continued. Prior to approving the
Plan, the Trustees requested and received from the Distributor and reviewed all
the information which they deemed necessary to arrive at an informed
determination. In making their determination, the Trustees considered: (1) the
benefits each Portfolio would be likely to obtain under the Plan, including that
without the compensation to individual brokers and the reimbursement of
distribution and account maintenance expenses of Dean Witter Reynolds's branch
offices made possible by the 12b-1 fees, Dean Witter Reynolds could not
establish and maintain a competitive and effective system for distribution and
servicing of Contract Owners and maintenance of their accounts; and (2) what
services would be provided under the Plan to Contract Owners. Based upon their
review, the Trustees, including each of the Independent Trustees, determined
that approval of the Plan would be in the best interests of each Portfolio and
would have a reasonable likelihood of continuing to benefit the Portfolio and
Contract Owners. In the Trustees' quarterly review of the Plan, they will
consider its continued appropriateness and the level of compensation provided
therein.

    The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval by the Class Y shareholders
of each affected Portfolio, and all material amendments to the Plan must also be
approved by the Trustees. The Plan may be terminated as to a Portfolio at any
time, without payment of any penalty, by vote of a majority of the Independent
Trustees or by a vote of a majority of the outstanding voting securities of the
Portfolio (as defined in the Investment Company Act) on not more than thirty
days' written notice to any other party to the Plan. So long as the Plan is in
effect, the election and nomination of Independent Trustees shall be committed
to the discretion of the Independent Trustees.

    No interested person of the Fund nor any Independent Trustee has any direct
financial interest in the operation of the Plan except to the extent that the
Distributor, the Investment Manager, Dean Witter Reynolds, MSDW Services Company
or certain of their employees may be deemed to have such an interest as a result
of benefits derived from the successful operation of the Plan or as a result of
receiving a portion of the amounts expended thereunder by the Portfolios.

E. OTHER SERVICE PROVIDERS

    (1) TRANSFER AGENT/DIVIDEND-DISBURSING AGENT

    The Transfer Agent is the transfer agent for each Portfolio's shares and the
Dividend Disbursing Agent for payment of dividends and distributions on
Portfolio shares. The principal business address of the Transfer Agent is
Harborside Financial Center, Plaza Two, Jersey City, NJ 07311.

    (2) CUSTODIAN AND INDEPENDENT ACCOUNTANTS


    The Bank of New York, 100 Church Street, New York, NY 10007, is the
Custodian of each Portfolio's assets other than those of the GLOBAL DIVIDEND
GROWTH PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO
and the INFORMATION PORTFOLIO. The Chase Manhattan Bank, One Chase Plaza, New
York, NY 10005, is the Custodian of the assets of the GLOBAL DIVIDEND GROWTH
PORTFOLIO, the PACIFIC GROWTH PORTFOLIO, the EUROPEAN GROWTH PORTFOLIO and the
INFORMATION PORTFOLIO. Any Portfolio's cash balances with the Custodian in
excess of $100,000 are unprotected by federal deposit insurance. These balances
may, at times, be substantial.



    PricewaterhouseCoopers LLP, 1177 Avenue of the Americas, New York, NY 10036,
served as independent accountants of the Fund for the fiscal year ended December
31, 1999. Effective July 1, 2000, PricewaterhouseCoopers LLP resigned and
Deloitte & Touche LLP, Two World Financial Center, New York, NY 10281, was
appointed the independent accountants of the Fund. The independent accountants
are responsible for auditing the annual financial statements of the Fund.


    (3) AFFILIATED PERSONS

    The Transfer Agent is an affiliate of the Investment Manager, of the
Sub-Advisor and of the Distributor. As Transfer Agent and Dividend Disbursing
Agent, the Transfer Agent's responsibilities include maintaining shareholder
accounts, reinvesting dividends, processing account registration changes,
handling purchase and redemption transactions, tabulating proxies and
maintaining shareholder records and lists. For these services, the Transfer
Agent receives an annual fee of $500 per account from each Portfolio and is
reimbursed for its out-of-pocket expenses in connection with such services.

F. CODES OF ETHICS

    The Fund, the Investment Manager, the Sub-Advisor and the Distributor have
each adopted a Code of Ethics pursuant to Rule 17j-1 under the Investment
Company Act. The Codes of Ethics are designed to detect and prevent improper
personal trading. The Codes of Ethics permit personnel subject to the Codes to
invest in securities, including securities that may be purchased, sold or held
by the Fund, subject to a number of restrictions and controls including
prohibitions against purchases of securities in an Initial Public Offering and a
preclearance requirement with respect to personal securities transactions.

VI. BROKERAGE ALLOCATION AND OTHER PRACTICES
--------------------------------------------------------------------------------

A. BROKERAGE TRANSACTIONS

    Subject to the general supervision of the Trustees, the Investment Manager
and, for the PACIFIC GROWTH PORTFOLIO and the EUROPEAN GROWTH PORTFOLIO, the
Sub-Advisor are responsible for decisions to buy and sell securities for each
Portfolio, the selection of brokers and dealers to effect the transactions, and
the negotiation of brokerage commissions, if any. Purchases and sales of
securities on a stock exchange are effected through brokers who charge a
commission for their services. In the over-the-counter market, securities are
generally traded on a "net" basis with dealers acting as principal for their own
accounts without a stated commission, although the price of the security usually
includes a profit to the dealer. The Fund also expects that securities will be
purchased at times in underwritten offerings where the price includes a fixed
amount of compensation, generally referred to as the underwriter's concession or
discount. Options and futures transactions will usually be effected through a
broker and a commission will be charged. Certain securities (e.g., certain money
market instruments) are purchased directly from an issuer, in which case no
commissions or discounts are paid.

B. COMMISSIONS

    Pursuant to an order of the SEC, the Portfolios may effect principal
transactions in certain money market instruments with Dean Witter Reynolds. The
Portfolios will limit their transactions with Dean Witter Reynolds to U.S.
Government and government agency securities, bank money instruments (i.e.,
certificates of deposit and bankers' acceptances) and commercial paper. The
transactions will be effected with Dean Witter Reynolds only when the price
available from Dean Witter Reynolds is better than that available from other
dealers.

    During the fiscal years ended December 31, 1997, 1998 and 1999, the Fund did
not effect any principal transactions with Dean Witter Reynolds.

    Brokerage transactions in securities listed on exchanges or admitted to
unlisted trading privileges may be effected through Dean Witter Reynolds, Morgan
Stanley & Co. and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect any portfolio transactions on an exchange
for the Portfolios, the commissions, fees or other remuneration received by the
affiliated broker or dealer must be reasonable and fair compared to the
commissions, fees or other remuneration paid to other brokers in connection with
comparable transactions involving similar securities being purchased or sold on
an exchange during a comparable period of time. This standard would allow the
affiliated broker or dealer to receive no more than the remuneration which would
be expected to be received by an unaffiliated broker in a commensurate
arm's-length transaction. Furthermore, the Trustees, including the Independent
Trustees, have adopted procedures which are reasonably designed to provide that
any commissions, fees or other remuneration paid to an affiliated broker or
dealer are consistent with the foregoing standard. The Fund does not reduce the
management fee it pays to the Investment Manager by any amount of the brokerage
commissions it may pay to an affiliated broker or dealer.

    During the fiscal year ended December 31, 1999, the PACIFIC GROWTH PORTFOLIO
paid a total of $605 in brokerage commissions to China International Capital,
which broker-dealer became an affiliate of the Investment Manager during 1999.
During the fiscal year ended December 31, 1999, the brokerage commissions paid
to China International Capital represented approximately 0.11% of the total
brokerage commissions paid by the PACIFIC GROWTH PORTFOLIO during the year and
were paid on account of transactions having an aggregate dollar value equal to
approximately 0.16% of the aggregate dollar value of all portfolio transactions
of the Portfolio during the year for which commissions were paid.

C. BROKERAGE SELECTION

    The policy of the Fund regarding purchases and sales of securities for the
Portfolios is that primary consideration will be given to obtaining the most
favorable prices and efficient executions of transactions. Consistent with this
policy, when securities transactions are effected on a stock exchange, the
Fund's policy is to pay commissions which are considered fair and reasonable
without necessarily determining that the lowest possible commissions are paid in
all circumstances. The Fund believes that a requirement always to seek the
lowest possible commission cost could impede effective portfolio management and
preclude the Fund and the Investment Manager (or, if applicable, the
Sub-Advisor) from obtaining a high quality of brokerage and research services.
In seeking to determine the reasonableness of brokerage commissions paid in any
transaction, the Investment Manager (or, if applicable, the Sub-Advisor) relies
upon its experience and knowledge regarding commissions generally charged by
various brokers and on its judgment in evaluating the brokerage and research
services received from the broker effecting the transaction. These
determinations are necessarily subjective and imprecise, as in most cases an
exact dollar value for those services is not ascertainable.

    The Fund anticipates that certain Portfolio transactions involving foreign
securities will be effected on foreign securities exchanges. Fixed commissions
on such transactions are generally higher than negotiated commissions on
domestic transactions. There is also generally less government supervision and
regulation of foreign securities exchanges and brokers than in the United
States.

    In seeking to implement each Portfolio's policies, the Investment Manager
(or, if applicable, the Sub-Advisor) effects transactions with those brokers and
dealers who the Investment Manager (or, if applicable, the Sub-Advisor) believes
provide the most favorable prices and are capable of providing efficient
executions. If the Investment Manager (or, if applicable, the Sub-Advisor)
believes the prices and executions are obtainable from more than one broker or
dealer, it may give consideration to placing portfolio transactions with those
brokers and dealers who also furnish research and other services to the Fund or
the Investment Manager (or, if applicable, the Sub-Advisor). The services may
include, but are not limited to, any one or more of the following: information
as to the availability of securities for purchase or sale; statistical or
factual information or opinions pertaining to investment; wire services; and
appraisals or evaluations of portfolio securities. The information and services
received by the Investment Manager (or, if applicable, the Sub-Advisor) from
brokers and dealers may be of benefit to the Investment Manager (or, if
applicable, the Sub-Advisor) in the management of accounts of some of its other
clients and may not in all cases benefit a Portfolio directly.

    The Investment Manager and the Sub-Advisor currently serve as investment
advisors to a number of clients, including other investment companies, and may
in the future act as investment advisors to others. It is the practice of the
Investment Manager (or, if applicable, the Sub-Advisor) to cause purchase and
sale transactions to be allocated among the Portfolios and others whose assets
it manages in such manner as it deems equitable. In making such allocations
among the Portfolios and other client accounts, various factors may be
considered, including the respective investment objectives, the relative size of
portfolio holdings of the same or comparable securities, the availability of
cash for investment, the size of investment commitments generally held and the
opinions of the persons responsible for managing the Portfolios and other client
accounts.

VII. CAPITAL STOCK AND OTHER SECURITIES
--------------------------------------------------------------------------------


    The shareholders of each Portfolio are entitled to a full vote for each full
share of beneficial interest held. The Fund is authorized to issue an unlimited
number of shares of beneficial interest. The Fund's shares of beneficial
interest are divided currently into seventeen Portfolios. All shares of
beneficial interest of the Fund are equal as to earnings, assets and voting
privileges except that each Class will have exclusive voting privileges with
respect to matters relating to distribution expenses borne by such Class (if
any) or any other matter in which the interests of one Class differ from the
interests of any other Class.


    The Fund's Declaration of Trust permits the Trustees to authorize the
creation of additional Portfolios and additional Classes of shares within any
Portfolio. The Trustees have not presently authorized any such additional series
or Classes of shares other than as set forth in the Prospectus for each Class.

                                       40
<PAGE>

    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 Investment Company Act or the Declaration of
Trust. Under certain circumstances, the Trustees may be removed by the actions
of the Trustees. In addition, under certain circumstances the shareholders may
call a meeting to remove Trustees and the Fund is required to provide assistance
in communicating with shareholders about such a meeting. The voting rights of
shareholders are not cumulative, so that holders of more than 50 percent of the
shares voting can, if they choose, elect all Trustees being selected, while the
holders of the remaining shares would be unable to elect any Trustees.


    Under Massachusetts law, shareholders of a business trust may, under certain
limited 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 notice
of such Fund obligations include such disclaimer, and provides for
indemnification 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, the possibility of the Fund being unable to
meet its obligations is remote and thus, in the opinion of Massachusetts counsel
to the Fund, the risk to Fund shareholders of personal liability is remote.

    Shareholders have the right to vote on the election of Trustees of the Fund
and on any and all matters on which by law or the provisions of the Fund's
By-Laws they may be entitled to vote. 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
established to fund the benefits under either a flexible premium deferred
variable annuity Contract or a flexible premium variable life insurance Contract
in accordance with instructions from the owners of such Contracts. Shareholders
of all Portfolios vote for a single set of Trustees.


    All of the Trustees, except for James F. Higgins, have been elected by the
shareholders of the Fund, most recently at a Special Meeting of Shareholders
held on May 21, 1997. The Trustees themselves have the power to alter the number
and the terms of office of the Trustees (as provided for in the Declaration of
Trust), and they may at any time lengthen or shorten their own terms or make
their terms of unlimited duration and appoint their own successors, provided
that always at least a majority of the Trustees has been elected by the
shareholders of the Fund.


    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.

    With respect to the submission to shareholder vote of a matter requiring
separate voting by Portfolio, the matter shall have been effectively acted upon
with respect to any Portfolio if a majority of the outstanding voting securities
of that Portfolio votes for the approval of the matter, notwithstanding that:
(1) the matter has not been approved by a majority of the outstanding voting
securities of any other Portfolio; or (2) the matter has not been approved by a
majority of the outstanding voting securities of the Fund. The voting rights of
shareholders are not cumulative, so that holders of more than 50 percent of the
shares voting can, if they choose, elect all Trustees being selected, while the
holders of the remaining shares would be unable to elect any Trustees.

VIII. PURCHASE, REDEMPTION AND PRICING OF SHARES
--------------------------------------------------------------------------------


A. PURCHASE/REDEMPTION OF SHARES


    Information concerning how Portfolio shares are offered (and how they are
redeemed) is provided in each of the Fund's Class X and Class Y PROSPECTUSES.

                                       41
<PAGE>
B. OFFERING PRICE

    The price of each Portfolio share, called "net asset value," is based on the
value of the Portfolio's securities. Net asset value per share of each of Class
X and Class Y shares is calculated by dividing the value of the portion of each
Portfolio's securities and other assets attributable to each Class,
respectively, less the liabilities attributable to each Class, respectively, by
the number of shares of the Class outstanding. The assets of each Class of
shares are invested in a single portfolio. The net asset value of each Class,
however, will differ because the Classes have different ongoing fees.

    The MONEY MARKET PORTFOLIO, however, utilizes the amortized cost method in
valuing its portfolio securities for purposes of determining the net asset value
of its shares. The MONEY MARKET PORTFOLIO utilizes the amortized cost method in
valuing its portfolio securities even though the portfolio securities may
increase or decrease in market value, generally in connection with changes in
interest rates. The amortized cost method of valuation involves valuing a
security at its cost at the time of purchase 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. While this method provides
certainty in valuation, it may result in periods during which value, as
determined by amortized cost, is higher or lower than the price the MONEY MARKET
PORTFOLIO would receive if it sold the investment. During such periods, the
yield to investors in the MONEY MARKET PORTFOLIO may differ somewhat from that
obtained in a similar company which uses mark-to-market values for all of its
portfolio securities. For example, if the use of amortized cost resulted in a
lower (higher) aggregate portfolio value on a particular day, a prospective
investor in the MONEY MARKET PORTFOLIO would be able to obtain a somewhat higher
(lower) yield than would result from investment in such a similar company and
existing investors would receive less (more) investment income. The purpose of
this method of calculation is to facilitate the maintenance of a constant net
asset value per share of $1.00.

    The use of the amortized cost method to value the portfolio securities of
the MONEY MARKET PORTFOLIO and the maintenance of the per share net asset value
of $1.00 is permitted pursuant to Rule 2a-7 of the Act (the "RULE") and is
conditioned on its compliance with various conditions contained in the
Rule including: (a) the Trustees are obligated, as a particular responsibility
within the overall duty of care owed to the Portfolio's shareholders, to
establish procedures reasonably designed, taking into account current market
conditions and the Portfolio's investment objectives, to stabilize the net asset
value per share as computed for the purpose of distribution and redemption at
$1.00 per share; (b) the procedures include (i) calculation, at such intervals
as the Trustees determine are appropriate and as are reasonable in light of
current market conditions, of the deviation, if any, between net asset value per
share using amortized cost to value portfolio securities and net asset value per
share based upon available market quotations with respect to such portfolio
securities; (ii) periodic review by the Trustees of the amount of deviation as
well as methods used to calculate it; and (iii) maintenance of written records
of the procedures, and the Trustees' considerations made pursuant to them and
any actions taken upon such consideration; (c) the Trustees should consider what
steps should be taken, if any, in the event of a difference of more than 1/2 of
1% between the two methods of valuation; and (d) the Trustees should take such
action as they deem appropriate (such as shortening the average portfolio
maturity, realizing gains or losses, withholding dividends or, as provided by
the Declaration of Trust, reducing the number of outstanding shares of the MONEY
MARKET PORTFOLIO) to eliminate or reduce to the extent reasonably practicable
material dilution or other unfair results to investors or existing shareholders
which might arise from differences between the two methods of valuation. Any
reduction of outstanding shares will be effected by having each shareholder
proportionately contribute to the MONEY MARKET PORTFOLIO'S capital the necessary
shares that represent the amount of excess upon such determination. Each
Contract Owner will be deemed to have agreed to such contribution in these
circumstances by allocating investment under his or her Contract to the MONEY
MARKET PORTFOLIO.

    Generally, for purposes of the procedures adopted under the Rule, the
maturity of a portfolio security is deemed to be the period remaining
(calculated from the trade date or such other date on which the MONEY MARKET
PORTFOLIO'S interest in the instrument is subject to market action) until the
date on which in accordance with the terms of the security the principal amount
must unconditionally be paid, or

                                       42
<PAGE>
in the case of a security called for redemption, the date on which the
redemption payment must be made.

    A variable rate security that is subject to a demand feature is deemed to
have a maturity equal to the period remaining until the principal amount can be
recovered through demand. A floating rate security that is subject to a demand
feature is deemed to have a maturity equal to the period remaining until the
principal amount can be recovered through demand.

    An "NRSRO" is a nationally recognized statistical rating organization. The
term "Requisite NRSROs" means (i) any two NRSROs that have issued a rating with
respect to a security or class of debt obligations of an issuer, or (ii) if only
one NRSRO has issued a rating with respect to such security or issuer at the
time a fund purchases or rolls over the security, that NRSRO.

    An Eligible Security is generally defined in the Rule to mean (i) a security
with a remaining maturity of 397 calendar days or less that has received a
short-term rating (or that has been issued by an issuer that has received a
short-term rating with respect to a class of debt obligations, or any debt
obligation within that class, that is comparable in priority and security with
the security) by the Requisite NRSROs in one of the two highest short-term
rating categories (within which there may be sub-categories or gradations
indicating relative standing); or (ii) a security: (A) that at the time of
issuance had a remaining maturity of more than 397 calendar days but that has a
remaining maturity of 397 calendar days or less; and (B) whose issuer has
received from the Requisite NRSROs a rating with respect to a class of debt
obligations (or any debt obligations within that class) that is now comparable
in priority and security with the security, in one of the two highest short-term
rating categories (within which there may be subcategories or gradations
indicating relative standing); or (iii) an unrated security that is of
comparable quality to a security meeting the requirements of (i) or (ii) above,
as determined by the Trustees. The MONEY MARKET PORTFOLIO will limit its
investments to securities that meet the requirements for Eligible Securities
including the required ratings by S&P or Moody's.

    As permitted by the Rule, the Board has delegated to the Fund's Investment
Manager, subject to the Board's oversight pursuant to guidelines and procedures
adopted by the Board, the authority to determine which securities present
minimal credit risks and which unrated securities are comparable in quality to
rated securities.

    Also, as required by the Rule, the MONEY MARKET PORTFOLIO will limit its
investments in securities, other than Government securities, so that, at the
time of purchase: (a) except as further limited in (b) below with regard to
certain securities, no more than 5% of its total assets will be invested in the
securities of any one issuer; and (b) with respect to Eligible Securities that
have received a rating in less than the highest category by any one of the
NRSROs whose ratings are used to qualify the security as an Eligible Security,
or that have been determined to be of comparable quality: (i) no more than 5% in
the aggregate of the Portfolio's total assets in all such securities, and
(ii) no more than the greater of 1% of total assets, or $1 million, in the
securities on any one issuer.

    The presence of a line of credit or other credit facility offered by a bank
or other financial institution which guarantees the payment obligation of the
issuer, in the event of a default in the payment of principal or interest of an
obligation, may be taken into account in determining whether an investment is an
Eligible Security, provided that the guarantee itself is an Eligible Security.

    The Rule further requires that the Money Market Portfolio limit its
investments to U.S. dollar-denominated instruments which the Trustees determine
present minimal credit risks and which are Eligible Securities. The Rule also
requires the Portfolio to maintain a dollar-weighted average portfolio maturity
(not more than 90 days) appropriate to its objective of maintaining a stable net
asset value of $1.00 per share and precludes the purchase of any instrument with
a remaining maturity of more than 397 days. (An Investment Restriction of the
Fund further precludes the Portfolio from investing in securities maturing more
than one year from the date of purchase.) Should the disposition of a portfolio
security result in a dollar-weighted average portfolio maturity of more than 90
days, the Portfolio will invest its available cash in such a manner as to reduce
such maturity to 90 days or less a soon as is reasonably practicable.

                                       43
<PAGE>
    If the Trustees determine that it is no longer in the best interests of the
MONEY MARKET PORTFOLIO and its shareholders to maintain a stable price of $1 per
share or if the Trustees believe that maintaining such price no longer reflects
a market-based net asset value per share, the board has the right to change from
an amortized cost basis of valuation to valuation based on market quotations.
The Fund will notify shareholders of the Portfolio of any such change.


    In the calculation of a Portfolio's net asset value: (1) an equity portfolio
security listed or traded on the New York or American Stock Exchange, NASDAQ, or
other exchange is valued at its latest sale price, 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 a security is traded on more than one exchange,
the security is 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. When market quotations are not readily available,
including circumstances under which it is determined by the Investment Manager
(or if applicable, the Sub-Advisor) 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 Trustees. 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.


    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.

    Certain of the Portfolios' securities (other than securities of 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.

    Listed options on securities are valued at the latest sale price on the
exchange on which they are listed unless no sales of such options have taken
place that day, in which case they will be valued at the mean between their
latest bid and asked prices. Unlisted options on debt securities and all options
on equity securities are valued at the mean between their latest bid and asked
prices. Futures are valued at the latest sale price on the commodities exchange
on which they trade unless the Trustees determine such price does not reflect
their market value, in which case they will be valued at their fair value as
determined in good faith under procedures established by and under the
supervision of 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 the Fund'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.

IX. TAXATION OF THE PORTFOLIOS AND SHAREHOLDERS
--------------------------------------------------------------------------------

    Each of the Portfolios is treated as a separate entity for federal tax
purposes. Each of the Portfolios intends to remain qualified as a regulated
investment company under Subchapter M of the Internal Revenue Code of 1986. As
such, each of the Portfolios will not be subject to federal income tax on its
net investment income and capital gains, if any, to the extent that it
distributes such income and capital gains

                                       44
<PAGE>
to its shareholders. Each of the Portfolios generally intends to distribute
sufficient income and gains so that each of the Portfolios will not pay
corporate income tax on its earnings.

    Section 817(h) of the Internal Revenue Code provides that the investments of
a separate account underlying a variable insurance contract (or the investments
of a mutual fund, the shares of which are owned by the variable separate
account) must be "adequately diversified" in order for the contract to be
treated as an annuity or life insurance for tax purposes. The Treasury
Department has issued regulations prescribing these diversification
requirements. Each Portfolio intends to comply with these requirements.

    Information concerning the federal income tax consequences to holders of the
underlying variable annuity or variable life insurance Contracts is contained in
the accompanying prospectus for the applicable Contract.

X. UNDERWRITERS
--------------------------------------------------------------------------------

    The Portfolios' shares are offered on a continuous basis. The Distributor,
as the principal underwriter of the shares, has certain obligations under the
Distribution Agreement concerning the distribution of the shares. These
obligations and the compensation the Distributor receives are described above in
the sections titled "Principal Underwriter" and "Rule 12b-1 Plan."

XI. CALCULATION OF PERFORMANCE DATA
--------------------------------------------------------------------------------

    The annualized current yield of the MONEY MARKET PORTFOLIO, as may be quoted
from time to time in advertisements and other communications to shareholders and
potential investors, is computed by determining, for a stated seven-day period,
the net change, exclusive of capital changes and including the value of
additional shares purchased with dividends and any dividends declared therefrom,
in the value of a hypothetical pre-existing account have a balance of one share
at the beginning of the period, subtracting a hypothetical charge which reflects
deductions from shareholder accounts (such as management fees), and dividing the
difference by the value of the account at the beginning of the base period to
obtain the base period return, and then multiplying the base period return by
(365/7).

    The MONEY MARKET PORTFOLIO'S annualized effective yield, as may be quoted
from time to time in advertisements and other communications to shareholders and
potential investors, is computed by determining (for the same stated seven-day
period as for the current yield), the net change, exclusive of capital changes
and including the value of additional shares purchased with dividends and any
dividends declared therefrom, in the value of a hypothetical pre-existing
account having a balance of one share at the beginning of the period,
subtracting a hypothetical charge reflecting deductions from shareholder
accounts, and dividing the difference by the value of the account at the
beginning of the base period to obtain the base period return, and then
compounding the based period return by adding 1, raising the sum to a power
equal to 365 divided by 7, and subtracting 1 from the result.

    The yields quoted in any advertisement or other communication should not be
considered a representation of the yields of the MONEY MARKET PORTFOLIO in the
future since the yield is not fixed. Actual yields will depend not only on the
type, quality and maturities of the investments held by the MONEY MARKET
PORTFOLIO and changes in interest rates on such investments, but also on changes
in the Portfolio's expenses during the period.

    Yield information may be useful in reviewing the performance of the Money
Market Portfolio and for providing a basis for comparison with other investment
alternatives. However, unlike bank deposits or other investments which typically
pay a fixed yield for a stated period of time, the Money Market Portfolio's
yield fluctuates. Furthermore, the quoted yield does not reflect charges which
may be imposed on the Contracts by the applicable Account and therefore is not
equivalent to total return under a Contract. (For a description of such charges,
see the prospectus for the Contracts which accompanies each of the Class X
PROSPECTUS and the Class Y PROSPECTUS for the Fund.)

    The current yield of the MONEY MARKET PORTFOLIO for the seven days ending
December 31, 1999 was 5.44%. The effective annual yield on 5.44% is 5.59%,
assuming daily compounding.

    From time to time the Fund may quote the "yield" of each of the SHORT-TERM
BOND PORTFOLIO, the QUALITY INCOME PLUS PORTFOLIO, the HIGH YIELD PORTFOLIO and
the UTILITIES PORTFOLIO in advertising and sales literature. Yield is calculated
for any 30-day period as follows: the amount of interest and/or dividend income
for each security in the Portfolio is determined in accordance with regulatory
requirements; the total for the entire portfolio constitutes the Portfolio's
gross income for the period. Expenses accrued during the period are subtracted
to arrive at "net investment income." The resulting amount is divided by the
product of the net asset value per share on the last day of the period
multiplied by the average number of Portfolio shares outstanding during the
period that were entitled to dividends. This amount is added to 1 and raised to
the sixth power. 1 is then subtracted from the result and the difference is
multiplied by 2 to arrive at the annualized 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 which, if quoted, would reduce the yield
quoted. For the 30-day period ended December 31, 1999, the yield of the
SHORT-TERM BOND PORTFOLIO, calculated pursuant to this formula, was 4.48%, the
yield of the QUALITY INCOME PLUS PORTFOLIO, calculated pursuant to this formula,
was 7.11%, the yield of the HIGH YIELD PORTFOLIO, calculated pursuant to this
formula, was 18.86%, and the yield of the UTILITIES PORTFOLIO, calculated
pursuant to this formula, was 2.33%.

    From time to time the Fund may quote the "total return" of each Portfolio in
advertising and sales literature. A Portfolio's "average annual total return"
represents an annualization of the Portfolio's total return over a particular
period and is computed by finding the annual percentage rate which will result
in the ending redeemable value of a hypothetical $1,000 investment made at the
beginning of a one, five or ten year period, or for the period from the date of
commencement of the Portfolio's operations, if shorter than any of the
foregoing. For the purpose of this calculation, it is assumed that all dividends
and distributions are reinvested. 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 quoted, would reduce the performance quoted.
The formula for computing the average annual total return involves a percentage
obtained by dividing the ending redeemable value by the amount of the initial
investment, taking a root of the quotient (where the root is equivalent to the
number of years in the period) and subtracting 1 from the result.

    The average annual total returns of 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 EQUITY PORTFOLIO, the S&P 500 INDEX PORTFOLIO,
the COMPETITIVE EDGE "BEST IDEAS" PORTFOLIO and the STRATEGIST PORTFOLIO for the
one, five and ten year periods (or for the period from the date of commencement
of the Portfolio's operations, if shorter than any of the foregoing) ended
December 31, 1999 were as follows:

    The INFORMATION PORTFOLIO had not commenced operations prior to the date of
this STATEMENT OF ADDITIONAL INFORMATION.


    The Fund quotes the "total return" of a Portfolio that has been in operation
for less than one year on an non-annualized basis. The Fund may compute the
aggregate total return of each of the SHORT-TERM BOND PORTFOLIO and the
AGGRESSIVE EQUITY PORTFOLIO (which commenced operations on May 3, 1999) for
specified periods by determining the aggregate percentage rate that will result
in the ending value of a hypothetical $1,000 investment made at the beginning of
the period. For the purpose of this calculation, it is assumed that all
dividends and distributions are reinvested. The formula for computing aggregate
total return involves a percentage obtained by dividing the ending value by the
initial $1,000 investment and subtracting 1 from the result. Based on the
foregoing calculation, the total returns of the SHORT-TERM BOND PORTFOLIO and
the AGGRESSIVE EQUITY PORTFOLIO for the period May 3, 1999 through December 31,
1999 were 1.56% and 46.08%, respectively. The Investment Manager assumed all
operating expenses of each of the SHORT-TERM BOND PORTFOLIO and the AGGRESSIVE
EQUITY PORTFOLIO until November 5, 1999. Without the waiver of fees and
assumption of expenses by the Investment Manager, the total returns of the
SHORT-TERM BOND and the AGGRESSIVE EQUITY PORTFOLIO would have been 0.94% and
45.88%, respectively.

    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 an Account. The Fund may also compute the aggregate total returns
of the Portfolios for specified periods by determining the aggregate percentage
rate which will result in the ending value of a hypothetical $1,000 investment
made at the beginning of the period. For the purpose of this calculation, it is
assumed that all dividends and distributions are reinvested. The formula for
computing aggregate total return involves a percentage obtained by dividing the
ending value (without the reduction for any charges imposed on the Contracts by
the applicable Account) by the initial $1,000 investment and subtracting 1 from
the result.

    Based on the foregoing calculation, the total returns of 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 EQUITY
PORTFOLIO, the S&P 500 INDEX PORTFOLIO, the COMPETITIVE EDGE "BEST IDEAS"

<S>                     <C>
Utilities*              Seek both capital appreciation and current income by investing in
                        equity and fixed income securities of companies engaged in the
                        utilities industry. Prior to August 5, 1999 the investment
                        objective was 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.
Income Builder          Seeks, as its primary objective, to earn reasonable income and,
                        as a secondary objective, growth of capital by investing
                        primarily in income-producing equity securities.
Dividend Growth         Seeks to provide reasonable current income and long-term growth
                        of income and capital by investing primarily in common stocks of
                        companies with a record of paying dividends and the potential for

* ON AUGUST 4, 1999, SHAREHOLDERS APPROVED A CHANGE IN THE INVESTMENT OBJECTIVE.

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.

The following is a summary of significant accounting policies:

A. VALUATION OF INVESTMENTS -- Money Market: securities are valued at amortized
cost which approximates market value. All remaining Portfolios: (1) an equity
security listed or traded on the New York, American or other domestic or foreign
stock exchange is valued at its latest sale price on

                                      141
<PAGE>
MORGAN STANLEY DEAN WITTER VARIABLE INVESTMENT SERIES
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1999, CONTINUED

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); (2) all other portfolio securities for which over-the-counter
market quotations are readily available are valued at the latest available bid
price prior to the time of valuation; (3) listed options are valued at the
latest sale price on the exchange on which they are listed unless no sales of
such options have taken place that day, in which case they are valued at the
mean between their latest bid and asked price; (4) when market quotations are
not readily available, including circumstances under which it is determined by
the Investment Manager (or, in the case of European Growth and Pacific Growth,
by Morgan Stanley Dean Witter Investment Management Inc. (the Sub-Advisor)) 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 Trustees
(valuation of debt 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); (5) certain of the Fund's portfolio securities may be valued
by an outside pricing service approved by the Trustees. The pricing service may
utilize a matrix system incorporating security quality, maturity and coupon as
the evaluation model parameters, and/or research and evaluations by its staff,
including review of broker-dealer market price quotations in determining what it
believes is the fair valuation of the securities valued by such pricing service;
and (6) short-term debt securities having a maturity date of more than sixty
days at the time of purchase are valued on a mark-to-market basis until sixty
days prior to maturity and thereafter at amortized cost based on their value on
the 61st day. Short-term debt securities having a maturity date of sixty days or
less at the time of purchase are valued at amortized cost.

B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Dividend income and other distributions are recorded on the ex-dividend date
except for certain dividends on foreign securities which are recorded as soon as
the Fund is informed after the ex-dividend date. Interest income is accrued
daily except where collection is not expected. Money Market amortizes premiums
and accretes discounts on securities owned; gains and losses realized upon the
sale of securities are based on amortized cost. Discounts for all other
Portfolios are accreted over the life of the respective securities.

C. ACCOUNTING FOR OPTIONS AND FUTURES CONTRACTS -- (1) Written options on debt
obligations, equities and foreign currency: when the Fund writes a call or put
option, an amount equal to the premium received is included in the Fund's
Statement of Assets and Liabilities as a liability which is

                                      142
<PAGE>
MORGAN STANLEY DEAN WITTER VARIABLE INVESTMENT SERIES
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1999, CONTINUED

subsequently marked-to-market to reflect the current market value of the option
written. If a written option either expires or the Fund enters into a closing
purchase transaction, the Fund realizes a gain or loss without regard to any
unrealized gain or loss on the underlying security or currency and the liability
related to such option is extinguished. If a written call option is exercised,
the Fund realizes a gain or loss from the sale of the underlying security or
currency and the proceeds from such sale are increased by the premium originally
received. If a put option which the Fund has written is exercised, the amount of
the premium originally received reduces the cost of the security which the Fund
purchases upon exercise of the option; (2) Purchased options on debt
obligations, equities and foreign currency: When the Fund purchases a call or
put option, the premium paid is recorded as an investment and is subsequently
marked-to-market to reflect the current market value. If a purchased option
expires, the Fund will realize a loss to the extent of the premium paid. If the
Fund enters into a closing sale transaction, a gain or loss is realized for the
difference between the proceeds from the sale and the cost of the option. If a
put option is exercised, the cost of the security sold upon exercise will be
increased by the premium originally paid. If a call option is exercised, the
cost of the security purchased upon exercise will be increased by the premium
originally paid; (3) Options on futures contracts: the Fund is required to
deposit cash, U.S. Government securities or other liquid portfolio securities as
"initial margin" and "variation margin" with respect to written call and put
options on futures contracts. If written option expires, the Fund realizes a
gain. If a written call or put option is exercised, the premium received will
decrease or increase the unrealized loss or gain on the futures contract. If the
Fund enters into a closing purchase transaction, the Fund realizes a gain or
loss without regard to any unrealized gain or loss on the underlying futures
contract and the liability related to such option is extinguished; and
(4) Futures contracts: a futures contract is an agreement between two parties to
buy and sell financial instruments at a set price on a future date. Upon
entering into such a contract, the Fund is required to pledge to the broker
cash, U.S. Government securities or other liquid portfolio securities equal to
the minimum initial margin requirements of the applicable futures exchange.
Pursuant to the contract, the Fund agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in the value of the contract.
Such receipts or payments known as variation margin are recorded by the Fund as
unrealized gains or losses. Upon closing of the contract, the Fund realizes a
gain or loss equal to the difference between the value of the contract at the
time it was opened and the value at the time it was closed.

D. FOREIGN CURRENCY TRANSLATION -- The books and records of the Portfolios
investing in foreign currency denominated transactions are translated into U.S.
dollars as follows: (1) the foreign currency market value of investment
securities, other assets and liabilities and forward foreign currency contracts
are translated at the exchange rates prevailing at the end of the period; and
(2) purchases,

                                      143
<PAGE>
MORGAN STANLEY DEAN WITTER VARIABLE INVESTMENT SERIES
NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1999, CONTINUED

sales, income and expenses are translated at the exchange rates prevailing on
the respective dates of such transactions. The resultant exchange gains and
losses are included in the Statement of Operations as realized and unrealized
gain/loss on foreign exchange transactions. Pursuant to U.S. Federal income tax
regulations, certain foreign exchange gains/losses included in realized and
unrealized gain/loss are included in or are a reduction of ordinary income for
federal income tax purposes. The Portfolios do not isolate that portion of the
results of operations arising as a result of changes in the foreign exchange
rates from the changes in the market prices of the securities.

E. FORWARD FOREIGN CURRENCY CONTRACTS -- Some of the Portfolios may enter into
forward foreign currency contracts which are valued daily at the appropriate
forward exchange rates. The resultant unrealized exchange gains and losses are
included in the Statement of Operations as unrealized gain/ loss on foreign
exchange transactions. The Portfolios record realized gains or losses on
delivery of the currency or at the time the forward contract is extinguished
(compensated) by entering into a closing transaction prior to delivery.

F. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply individually
for each Portfolio with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its taxable income to
its shareholders. Accordingly, no federal income tax provision is required.

G. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the record date. The amount of dividends
and distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These book/tax differences are
either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification. Dividends and distributions which
exceed net investment income and net realized capital gains for financial
reporting purposes but not for tax purposes are reported as dividends in excess
of net investment income or distributions in excess of net realized capital
gains. To the extent they exceed net investment income and net realized capital
gains for tax purposes, they are reported as distributions of paid-in-capital.

H. EXPENSES -- Direct expenses are charged to the respective Portfolio and
general Fund expenses are allocated on the basis of relative net assets or
equally among the Portfolios.

Portfolio ("Capital Appreciation"), Equity obtained a net capital loss carryover
of approximately $6,329,000 from Capital Appreciation. Utilization of this
carryover is subject to limitations imposed by the Internal Revenue Code and
Treasury Regulations. During the year ended December 31, 1999, Equity utilized
approximately $1,309,000 of this carryover. The following Portfolios also
utilized approximate net capital loss carryovers: Pacific Growth - $8,180,000;
Strategist - $6,900,000.

Net capital and net foreign currency losses incurred after October 31
("post-October losses") within the taxable year are deemed to arise on the first

attributable to the mark-to-market of futures contracts and High Yield had
temporary differences attributable to interest on bonds in default. Global
Dividend Growth and Pacific Growth had permanent differences attributable to tax
adjustments on PFICs sold by the Portfolios.

5. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS

Global Dividend Growth, European Growth, Pacific Growth and Competitive Edge
"Best Ideas" may enter into forward foreign currency contracts ("forward
contracts") to facilitate settlement of foreign currency denominated portfolio
transactions or to manage foreign currency exposure associated with foreign
currency denominated securities. Such Portfolios may also purchase and write put
options on foreign currencies ("options") in which the Portfolios' securities
are denominated to protect against a decline in value of such securities due to
currency devaluations.

Forward contracts and options involve elements of market risk in excess of the
amounts reflected in the Statement of Assets and Liabilities. The Portfolios
bear the risk of an unfavorable change in the foreign exchange rates underlying
the forward contracts. Risks may also arise upon entering into these forward
contracts and options from the potential inability of the counterparties to meet
the terms of their contracts.

S&P 500 Index may purchase and sell stock index futures ("futures contacts") for
the following reasons: to simulate full investment in the S&P 500 INDEX while
retaining a cash balance for fund 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.

These futures contracts involve elements of market risk in excess of the amount
reflected in the Statement of Assets and Liabilities. S&P 500 Index bears the
risk of an unfavorable change in the value of the underlying securities.

At December 31, 1999, European Growth's investments in securities of issuers in
the United Kingdom represented 28.1% of the Portfolio's net assets. Pacific
Growth's investments in securities of issuers in Japan represented 44.4% of the
Portfolio's net assets. These investments, which involve risks and
considerations not present with respect to U.S. securities, may be affected by
economic or political developments in these regions.

At December 31, 1999, Global Dividend Growth's, European Growth's and Pacific
Growth's cash balance consisted principally of interest bearing deposits with
Chase Manhattan Bank N.A., the custodian of each Portfolio.

REPORT OF INDEPENDENT ACCOUNTANTS

TO THE SHAREHOLDERS AND TRUSTEES
OF MORGAN STANLEY DEAN WITTER VARIABLE INVESTMENT SERIES

In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of 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 Equity Portfolio, the
S&P 500 Index Portfolio, the Competitive Edge "Best Ideas" Portfolio, the
Strategist Portfolio, the Aggressive Equity Portfolio and the Short-Term Bond
Portfolio (constituting Morgan Stanley Dean Witter Variable Investment Series,
hereafter referred to as the "Fund") at December 31, 1999, the results of each
of their operations for the year or period then ended, the changes in each of
their net assets and the financial highlights for each of the periods presented,
in conformity with accounting principles generally accepted in the United
States. These financial statements and financial highlights (hereafter referred
to as "financial statements") are the responsibility of the Fund's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits of these financial statements in
accordance with auditing standards generally accepted in the United States,
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at December 31, 1999 by correspondence with the
custodians and brokers, provide a reasonable basis for the opinion expressed
above.

RATINGS OF CORPORATE DEBT INSTRUMENTS INVESTMENTS

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.

    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.

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 IBCA, INC. ("FITCH")

                                  BOND RATINGS

    Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The rating
represents Fitch's assessment of the issuer's ability to meet the obligations of
a specific debt issue or class of debt in a timely manner.

    The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer

                                      162
<PAGE>
and any guarantor, as well as the economic and political environment that might
affect the issuer's future financial strength and credit quality.

    Fitch ratings do not reflect any credit enhancement that may be provided by
insurance policies or financial guarantees unless otherwise indicated.

    Bonds carrying the same rating are of similar but not necessarily identical
credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.

    Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.

    Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts, and other sources Fitch believes to be
reliable. Fitch does not audit or verify the truth or accuracy of such
information. Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.

<TABLE>
<S>              <C>
AAA              Bonds 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.

AA               Bonds considered to be investment grade and of very high
                 credit quality. The obligor's ability to pay interest and
                 repay principal is very strong, although not quite as strong
                 as bonds rated "AAA." Because bonds rated in the "AAA" and
                 "AA" categories are not significantly vulnerable to
                 foreseeable future developments, short-term debt of these
                 issuers is generally rated "F-1+."

A                Bonds 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              Bonds 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 have adverse impact on these
                 bonds, and therefore impair timely payment. The likelihood
                 that the ratings of these bonds will fall below investment
                 grade is higher than for bonds with higher ratings.

Plus (+) or      Plus and minus signs are used with a rating symbol to
Minus (-)        indicate the relative position of a credit within the rating
                 category. Plus and minus signs, however, are not used in
                 the"AAA" category.

NR               Indicates that Fitch does not rate the specific issue.

Conditional      A conditional rating is premised on the successful
                 completion of a project or the occurrence of a specific
                 event.

Suspended        A rating is suspended when Fitch deems the amount of
                 information available from the issuer to be inadequate for
                 rating purposes.

Withdrawn        A rating will be withdrawn when an issue matures or is
                 called or refinanced and, at Fitch's discretion, when an
                 issuer fails to furnish proper and timely information.

FitchAlert       Ratings are placed on FitchAlert to notify investors of an
                 occurrence that is likely to result in a rating change and
                 the likely direction of such change. These are designated as
                 "Positive," indicating a potential upgrade, "Negative," for
                 potential downgrade, or "Evolving," where ratings may be
                 raised or lowered. FitchAlert is relatively short-term, and
                 should be resolved within 12 months.

                 described as "Positive" or "Negative." The absence of a

    SPECULATIVE GRADE BOND RATINGS: Fitch speculative grade bond ratings provide
a guide to investors in determining the credit risk associated with a particular
security. The ratings ("BB" to "C") represent Fitch's assessment of the
likelihood of timely payment of principal and interest in accordance with the
terms of obligation for bond issues not in default. For defaulted bonds, the
rating ("DDD" to "D") is an assessment of the ultimate recovery value through
reorganization or liquidation.

    The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the issuer's
future financial strength.

    Bonds that have the rating are of similar but not necessarily identical
credit quality since rating categories cannot fully reflect the differences in
degrees of credit risk.

<TABLE>
<S>          <C>
BB           Bonds are considered speculative. The obligor's ability to
             pay interest and repay principal may be affected over time
             by adverse economic changes. However, business and finan-
             cial alternatives can be identified which could assist the
             obligor in satisfying its debt service requirements.

B            Bonds are considered highly speculative. While bonds in this
             class are currently meeting debt service requirements, the
             probability of continued timely payment of principal and
             interest reflects the obligor's limited margin of safety and
             the need for reasonable business and economic activity
             throughout the life of the issue.

CCC          Bonds have certain identifiable characteristics which, if
             not remedied, may lead to default. The ability to meet
             obligations requires an advantageous business and economic
             environment.

CC           Bonds are minimally protected. Default in payment of
             interest and/or principal seems probable over time.

C            Bonds are in imminent default in payment of interest or
             principal.

DDD          Bonds are in default on interest and/or principal payments.
DD and D     Such bonds are extremely speculative and should be valued on
             the basis of their ultimate recovery value in liquidation or
             reorganization of the obligor. "DDD" represents the highest
             potential for recovery on these bonds, and "D" represents
             the lowest potential for recovery.

Plus(+) or   Plus and minus signs are used with a rating symbol to
Minus(-)     indicate the relative position of a credit within the rating
             category. Plus and minus signs, however, are not used in the
             "DDD," "DD," or "D" categories.
</TABLE>

                               SHORT-TERM RATINGS

    Fitch's short-term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years, including commercial
paper, certificates of deposit, medium-term notes, and municipal and investment
notes.

    The short-term rating places greater emphasis than a long-term rating on the
existence of liquidity necessary to meet the issuer's obligations in a timely
manner.

    Fitch short-term ratings are as follows:

<TABLE>
<S>   <C>
F-1+  Exceptionally Strong Credit Quality. Issues assigned this
      rating are regarded as having the strongest degree of
      assurance for timely payment.

<TABLE>
<S>   <C>
F-1   Very Strong Credit Quality. Issues assigned this rating
      reflect an assurance of timely payment only slightly less in
      degree than issues rated "F-1+."

F-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 for issues assigned
      "F-1+" and "F-1" ratings.

F-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
      changes could cause these securities to be rated below in
      investment grade.

F-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   The 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.

    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).

              or into a higher or lower quality rating grade.

CCC           Well below investment grade securities. May be in default or
              considerable uncertainty exists as to timely payment of
              principal, interest or preferred dividends. Protection

              principal and/or interest payments.

DP            Preferred stock with dividend arrearages.
</TABLE>

                               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.

<TABLE>
<S>               <C>
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
                  factors. Risk factors are minor.
Duff-             High certainty of timely payment. Liquidity factors are strong
                  and supported by good fundamental protection factors. Risk
                  factors are very small.

B. Category 2:    Good Grade
Duff 2            Good certainty of timely payment. Liquidity factors and
                  company fundamentals are sound. Although ongoing funding needs
                  may enlarge total financing requirements, access to capital
                  markets is good. Risk factors are small.

C. Category 3:    Satisfactory Grade
Duff 3            Satisfactory liquidity and other protection factors qualify
                  issue as to investment grade. Risk factors are larger and
                  subject to more variation. Nevertheless, timely payment is
                  expected.

D. Category 4:    Non-investment Grade
Duff 4            Speculative investment characteristics. Liquidity is not
                  sufficient to insure against disruption in debt service.
                  Operating factors and market access may be subject to a high
                  degree of variation.

E. Category 5:    Default
Duff 5            Issuer failed to meet scheduled principal and/or interest
                  payments.

Item 24.  PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH THE FUND.

            None

Item 25.  INDEMNIFICATION.

     Pursuant to Section 5.3 of the Registrant's Declaration of Trust and under
Section 4.8 of the Registrant's By-Laws, the indemnification of the Registrant's
trustees, officers, employees and agents is permitted if it is determined that
they acted under the belief that their actions were in or not opposed to the
best interest of the Registrant, and, with respect to any criminal proceeding,
they had reasonable cause to believe their conduct was not unlawful. In
addition, indemnification is permitted only if it is determined that the actions
in question did not render them liable by reason of willful misfeasance, bad
faith or gross negligence in the performance of their duties or by reason of
reckless disregard of their obligations and duties to the Registrant. Trustees,
officers, employees and agents will be indemnified for the expense of litigation
if it is determined that they are entitled to indemnification against any
liability established in such litigation. The Registrant may also advance money
for these expenses provided that they give


                                       3
<PAGE>

their undertakings to repay the Registrant unless their conduct is later
determined to permit indemnification.

          Pursuant to Section 5.2 of the Registrant's Declaration of Trust and
paragraph 8 of the Registrant's Investment Management Agreement, neither the
Investment Manager nor any trustee, officer, employee or agent of the Registrant
shall be liable for any action or failure to act, except in the case of bad
faith, willful misfeasance, gross negligence or reckless disregard of duties to
the Registrant.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 (the "Act") may be permitted to trustees, officers and
controlling persons of the Registrant pursuant to the foregoing provisions or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a trustee, officer, or controlling
person of the Registrant in connection with the successful defense of any
action, suit or proceeding) is asserted against the Registrant by such trustee,
officer or controlling person in connection with the shares being registered,
the Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act, and will be governed by the final adjudication of such
issue.

          The Registrant hereby undertakes that it will apply the
indemnification provision of its by-laws in a manner consistent with Release
11330 of the Securities and Exchange Commission under the Investment Company Act
of 1940, so long as the interpretation of Sections 17(h) and 17(i) of such Act
remains in effect.

          Registrant, in conjunction with the Investment Manager, Registrant's
Trustees, and other registered investment management companies managed by the
Investment Manager, maintains insurance on behalf of any person who is or was a
Trustee, officer, employee, or agent of Registrant, or who is or was serving at
the request of Registrant as a trustee, director, officer, employee or agent of
another trust or corporation, against any liability asserted against him and
incurred by him or arising out of his position. However, in no event will
Registrant maintain insurance to indemnify any such person for any act for which
Registrant itself is not permitted to indemnify him.
