                            PAINEWEBBER SERIES TRUST
                          1285 Avenue of the Americas
                            New York, New York 10019
   
PaineWebber Series Trust ("Fund") is a professionally managed, open-end
investment company that offers the nine series of shares ("Portfolios") listed
below. All the Portfolios except the Global Income Portfolio are diversified,
and each has its own investment objective and policies. Shares of each
Portfolio are offered only to insurance company separate accounts that fund
certain variable contracts ("Contracts"). Advisory and administrative services
are provided to the Fund by Mitchell Hutchins Asset Management Inc. ("Mitchell
Hutchins"), a wholly owned subsidiary of PaineWebber Incorporated
("PaineWebber"), and certain Portfolios, as indicated below, have sub-advisers.
    
  * The MONEY MARKET PORTFOLIO seeks maximum current income consistent with
    liquidity and conservation of capital. This Portfolio invests in high
    grade money market instruments and repurchase agreements secured by such
    instruments. An investment in the Portfolio is neither insured nor
    guaranteed by the U.S. government. While the Portfolio seeks to maintain
    a stable net asset value of $1.00 per share, there can be no assurance
    that it will be able to do so.
     
  * The STRATEGIC FIXED INCOME PORTFOLIO seeks total return consisting of
    capital appreciation and income. This Portfolio invests primarily in
    fixed income securities of varying maturities with a dollar-weighted
    average portfolio duration between three and eight years. Pacific
    Investment Management Company serves as sub-adviser to this Portfolio.
           
  * The HIGH GRADE FIXED INCOME PORTFOLIO primarily seeks current income
    consistent with the preservation of capital and secondarily seeks
    capital appreciation. This Portfolio invests primarily in debt
    securities issued or guaranteed by the U.S. government, its agencies or
    instrumentalities and high quality corporate debt securities and
    mortgage-backed and asset-backed securities of private issuers.     
 
  * The GLOBAL INCOME PORTFOLIO primarily seeks high current income and
    secondarily seeks capital appreciation. This Portfolio invests
    principally in high quality debt securities of foreign and U.S. issuers.
          
  * The ASSET ALLOCATION PORTFOLIO seeks a high total return with low
    volatility. This Portfolio operates as a balanced fund and invests
    primarily in a combination of equity securities, investment grade debt
    obligations and money market instruments, based on Mitchell Hutchins'
    assessment of the optimal allocation of the Portfolio's assets.     
     
  * The GROWTH AND INCOME PORTFOLIO seeks current income and capital growth.
    This Portfolio invests primarily in dividend-paying equity securities
    believed by Mitchell Hutchins to have the potential for rapid earnings
    growth.     
     
  * The GROWTH PORTFOLIO seeks long-term capital appreciation. This
    Portfolio invests primarily in equity securities of companies that, in
    the judgment of Mitchell Hutchins, have substantial potential for
    capital growth.     
 
  * The AGGRESSIVE GROWTH PORTFOLIO seeks to maximize long-term capital
    appreciation. This Portfolio invests primarily in the common stocks of
    U.S. companies. Nicholas-Applegate Capital Management serves as sub-
    adviser to this Portfolio.
 
  * The GLOBAL GROWTH PORTFOLIO seeks long-term capital appreciation. This
    Portfolio invests primarily in common stocks of companies based in the
    United States, Europe, Japan and the Pacific Basin. GE Investment
    Management Incorporated serves as the sub-adviser to this Portfolio.

(1) Total return is calculated assuming a $1,000 investment on the first day
    of each period reported, reinvestment of all dividends and capital gain
    distributions at net asset value on the payable date, and a sale at net
    asset value on the last day of each period reported. Total returns for
    periods less than one year are not annualized.
** During certain periods presented above, Mitchell Hutchins agreed to
   reimburse the Portfolio for a portion of its operating expenses and waived
   all or a portion of its advisory fee. If such reimbursements and waivers
   had not been made, the annualized ratio of expenses to average net assets
   and the annualized ratio of net investment income to average net assets
   would have been 2.04% and 6.11%, 2.17% and 6.99%, 2.36% and 4.94%, and
   4.60% and 2.34%, respectively, for the years ending December 31, 1990, 1989

                THE FUND, ITS INVESTMENT OBJECTIVES AND POLICIES
   
The Fund is a professionally managed mutual fund. The Fund offers nine
Portfolios, each of which represents a segregated, separately managed portfolio
of securities with its own investment objective, as set forth on page PW 1, and
its own investment policies, which are summarized on page PW 1 and set forth in
more detail below. There can be no assurance that any Portfolio's investment
objective will be met. The Global Income Portfolio is managed as a non-
diversified investment company; the other Portfolios are all managed as
diversified investment companies.     
 
Shares of each Portfolio are offered only to insurance company separate
accounts that fund the Contracts. An insurance company separate account's
interest is limited to the Portfolio(s) in which the separate account invests.
Separate accounts may purchase or redeem shares at net asset value without any
sales or redemption charge. Fees and charges imposed by the separate account,
however, will affect the actual return to the holder of a Contract. A separate
account may also impose certain restrictions or limitations on the allocation
of purchase payments or Contract value to one or more Portfolios, and not all
Portfolios may be available in connection with a particular Contract.
Prospective investors should consult the applicable Contract prospectus for
information regarding fees and expenses of the Contract and separate account
and any applicable restrictions or limitations.
 
Shares of the Portfolios are offered to the separate account of PaineWebber
Life Insurance Company and shares of certain Portfolios are also offered to the
separate accounts of unaffiliated insurance companies ("shared funding").
Shares of the Portfolios may serve as the underlying investments for both
annuity and life insurance Contracts ("mixed funding"). Due to differences in
tax treatment or other considerations, the interests of various Contract owners
might at some time be in conflict. The Fund currently does not foresee any such
conflict. However, the Fund's board of trustees intends to monitor events to
identify any material irreconcilable conflict that may arise and to determine
what action, if any, should be taken in response to such conflict. If such a
conflict were to occur, one or more insurance companies' separate accounts
might be required to withdraw its investments in one or more Portfolios. This
might force a Portfolio to sell securities at disadvantageous prices.
 
The MONEY MARKET PORTFOLIO invests in high grade money market instruments, with
remaining maturities of 13 months or less, and repurchase agreements secured by
such instruments and maintains a dollar-weighted average portfolio maturity of
90 days or less. These instruments include (1) U.S. government securities
(which may or may not be backed by the full faith and credit of the United
States), (2) obligations (including certificates of deposit, bankers'
acceptances and similar obligations) of U.S. banks, including foreign branches
of domestic banks and domestic branches of foreign banks, having total assets
in excess of $1.5 billion at the time of purchase, (3) interest-bearing savings
deposits in U.S. commercial and savings banks having total assets of $1.5
billion or less, provided that the principal amounts at each such bank are
fully insured by the Federal Deposit Insurance Corporation and the aggregate
amount of such deposits (plus interest earned) does not exceed 5% of the
Portfolio's asset value and (4) commercial paper and other short-term corporate
obligations including variable and floating rate securities and participation
interests. Participation interests are pro rata interests in securities held by
others.
 
The commercial paper and other short-term corporate obligations purchased by
the Money Market Portfolio consist only of obligations that Mitchell Hutchins
determines, pursuant to procedures adopted by the Fund's board of trustees,
present minimal credit risks and are either (1) rated in the highest short-term
rating category by at least two nationally recognized statistical rating
organizations ("NRSROs"), (2) rated in the highest short-term rating category
by a single NRSRO if only that NRSRO has assigned the obligations a short-term
rating or (3) unrated, but determined by Mitchell Hutchins to be of comparable
quality ("First Tier Securities"). The Money Market Portfolio
 
                                     PW 10
<PAGE>
 
generally may invest no more than 5% of its total assets in the securities of a
single issuer (other than securities issued by the U.S. government, its
agencies or instrumentalities).
   
The STRATEGIC FIXED INCOME PORTFOLIO invests in a portfolio of fixed income
securities of varying maturities with a dollar-weighted average portfolio
duration between three and eight years. Portfolio holdings will be invested in
areas of the bond market (based on quality, sector, coupon or maturity) that
its sub-adviser, Pacific Investment Management Company ("PIMCO"), believes to
be relatively undervalued. Under normal circumstances, the Portfolio invests at
least 65% of its assets in fixed income securities, which include obligations
issued or guaranteed by the U.S. government, its agencies and
instrumentalities, corporate and other debt obligations, convertible
securities, mortgage- and asset-backed securities, obligations of foreign
governments or their subdivisions, agencies or instrumentalities, obligations
of supranational and quasi-governmental entities, commercial paper,
certificates of deposit, money market instruments, foreign currency exchange-
related securities and loan participations and assignments. The Portfolio may
invest up to 35% of its total assets in privately issued mortgage-related
securities. All of the securities purchased for the Portfolio will be
investment grade, except that the Portfolio may invest up to 20% of its total
assets in securities rated below investment grade, but rated at least B by
Standard & Poor's ("S&P") or Moody's Investors Service Inc. ("Moody's"),
assigned a comparable rating by another nationally recognized statistical
ratings service ("NRSRO") or, if unrated, determined by the sub-adviser to be
of comparable quality. Securities rated below investment grade are commonly
known as "junk bonds." The Portfolio may invest up to 10% of its assets in
securities denominated in foreign currencies and dollar-denominated debt of
foreign issuers. In addition, the Portfolio may invest up to 10% of its assets
in Yankee bonds and Eurodollar bonds combined. Yankee bonds are U.S. dollar-
denominated obligations of foreign issuers and Eurodollar bonds are U.S.
dollar-denominated obligations of domestic issuers that are held outside the
United States, primarily in Europe.     
   
The HIGH GRADE FIXED INCOME PORTFOLIO invests in U.S. government securities,
which include U.S. Treasury obligations and obligations issued or guaranteed by
U.S. government agencies or instrumentalities, including mortgage-backed
securities. The Portfolio may also invest in corporate debt securities,
including corporate bonds, debentures and non-convertible fixed income
preferred stocks, and may invest in mortgage- and asset-backed securities of
private issuers. The Portfolio will invest only in those debt securities of
private issuers that are, at the time of purchase, rated within one of the two
highest grades assigned by S&P or Moody's, assigned a comparable rating by
another NRSRO or, if unrated, determined by Mitchell Hutchins to be of
comparable quality, except that the Portfolio may invest up to 20% of its total
assets in corporate debt securities of U.S. issuers rated at least A at the
time of purchase by S&P or Moody's, assigned a comparable rating by another
NRSRO or, if unrated, determined by Mitchell Hutchins to be of comparable
quality. The Portfolio may invest up to 15% of its total assets in U.S. dollar-
denominated bonds sold in the United States by foreign issuers if the
securities are traded on recognized U.S. exchanges or in the U.S. over-the-
counter ("OTC") market. The Portfolio will not invest more than 25% of its
total assets in mortgage- and asset-backed securities of private issuers. No
more than 55% of the total assets of the Portfolio may be represented by U.S.
Treasury obligations to assure the Portfolio's compliance with the
diversification requirements imposed by the Internal Revenue Code on segregated
asset accounts used to fund variable annuity contracts. Mitchell Hutchins will
seek to vary the average maturity of the Portfolio's securities depending on
Mitchell Hutchin's perception of future interest rate movements, so that the
average maturity will be shortened when Mitchell Hutchins believes that
interest rates may rise and will be lengthened when Mitchell Hutchins
anticipates a decline in interest rates.     
 
The GLOBAL INCOME PORTFOLIO invests principally in high quality debt securities
of foreign and U.S. issuers. Debt securities will be considered high quality if
they are assigned one of S&P's or Moody's
 
                                     PW 11
<PAGE>
 
   
two highest ratings, comparably rated by another NRSRO or, if unrated,
determined by Mitchell Hutchins to be of comparable quality. Normally, at least
65% of the Portfolio's total assets are invested in high quality debt
securities, denominated in foreign currencies or U.S. dollars, that are issued
or guaranteed by foreign and U.S. governments or their agencies,
instrumentalities or political subdivisions or by supranational organizations
such as the International Bank for Reconstruction and Development ("World
Bank"), or that are issued by foreign and U.S. companies, banks and bank
holding companies. Such issuers will be located in at least five of the
following countries: Australia, Austria, Belgium, Canada, Denmark, Finland,
France, Germany, Hong Kong, Ireland, Italy, Japan, the Netherlands, New
Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, Thailand, the
United Kingdom and the United States. No more than 20% of the Portfolio's total
assets will be invested in securities of issuers located in any one country,
except that the Portfolio may invest up to 35% of its total assets in
securities of issuers located in any one of the following countries: Australia,
Canada, France, Germany, Japan and the United Kingdom. There is no limit on the
amount of assets that may be invested in securities of U.S. issuers. Mitchell
Hutchins expects that normally more than 50% of the Portfolio's total assets
will be invested in U.S. and foreign government securities in order to minimize
credit risk and to capitalize on opportunities that historically have been
presented by, and are perceived to exist today with respect to, such
instruments. Up to 35% of the Portfolio's total assets may be invested in
investment grade debt securities rated below the two highest grades assigned by
a NRSRO or, if unrated, determined by Mitchell Hutchins to be of comparable
quality. Within this 35% limitation, the Portfolio may invest up to 20% of its
total assets in sovereign debt securities rated below but no lower than BB by
S&P, Ba by Moody's, comparably rated by another NRSRO or, in the case of such
securities assigned a commercial paper rating, no lower than B by S&P or
comparably rated by another NRSRO or, if unrated determined by Mitchell
Hutchins to be of comparable quality. Mitchell Hutchins will purchase such
securities for the Portfolio only when it concludes that the anticipated return
to the Portfolio on such investment warrants exposure to the additional level
of risk. Fundamental economic strength, credit quality and currency and
interest rate trends are the principal determinants of the various country,
geographic and industry sector weightings within the Portfolio. Up to 5% of the
Portfolio's total assets may be invested in debt securities convertible into
equity, although the Portfolio has no current intention of converting such
securities into equity or holding them as equity upon conversion.     
   
The Global Income Portfolio is "non-diversified," as that term is defined in
the Investment Company Act of 1940 ("1940 Act"), but intends to continue to
qualify as a "regulated investment company" for federal income tax purposes.
This means, in general, that although more than 5% of the Portfolio's total
assets may be invested in the securities of one issuer (including a foreign
government), at the close of each quarter of the Portfolio's taxable year the
aggregate amount of such holdings may not exceed 50% of the value of its total
assets, and no more than 25% of the value of its total assets may be invested
in the securities of a single issuer. To the extent that the Portfolio at times
may hold the securities of a smaller number of issuers than if it were
"diversified" (as defined in the 1940 Act), the Portfolio will at such times be
subject to greater risk with respect to its portfolio securities than a fund
that invests in a broader range of securities, because changes in the financial
condition or market assessments of a single issuer may cause greater
fluctuations in the Portfolio's total return and the net asset value of its
shares.     
          
The ASSET ALLOCATION PORTFOLIO operates as a balanced fund and invests
primarily in a combination of equity securities, investment grade debt
obligations and money market instruments, based on Mitchell Hutchins'
assessment of the optimal allocation of the Portfolio's assets. The Portfolio
seeks to maintain a dollar-weighted average maturity for its fixed income
investments of three to ten years. Under normal conditions, at least 25% of the
Portfolio's assets will be invested in debt obligations, including money market
instruments. Mitchell Hutchins believes that capital market returns reflect the
consensus expectations for key economic variables, such as interest rates,
profit growth and     
 
                                     PW 12
<PAGE>
 
   
inflation, and that superior performance can be obtained by reallocating assets
from time to time before changes in the consensus outlook have been fully
discounted by the market. To implement this strategy, Mitchell Hutchins
regularly surveys market participants and generates a consensus forecast of
economic variables affecting returns on equity, fixed income and money market
investments. Mitchell Hutchins then applies fundamental valuation techniques to
the consensus date to determine what it believes is the optimal asset
allocation for the Portfolio. Portfolio managers specializing in each asset
class then select specific securities for their allocated portions of the
portfolio. Mitchell Hutchins regularly monitors market outlooks and changes
asset allocations when there are significant changes in expected returns.     
   
Equity Securities. In selecting equity securities for the Portfolio, Mitchell
Hutchins follows a disciplined methodology under which stocks from a universe
of approximately 2,000 medium to large capitalization (generally at least $300
million) companies are ranked utilizing quantitative measures of value,
earnings and price momentum in the context of Mitchell Hutchins' economic
forecast. Stocks are selected for the Portfolio based on fundamental analysis
of the highest ranking stocks.     
   
Debt Securities. The Portfolio's investments in debt securities are based on
analyses of the maturity structure and the risk structure (comparing yields on
U.S. Treasury securities to yields on riskier types of debt securities). The
Portfolio may invest in a broad range of investment grade bonds, securities
issued or guaranteed by the U.S. government, its agencies or instrumentalities,
including mortgage-backed securities, and other fixed income securities. The
maturity of a mortgage-backed security is deemed to be its effective life
(i.e., the average time in which it is expected that the principal amount of
the security will be repaid), as estimated by Mitchell Hutchins based upon
scheduled principal amortization and an anticipated rate of principal
prepayments, which, in turn, is based upon past prepayment patterns, prevailing
interest rates and other factors. The effective life of a mortgage-backed
security generally is substantially shorter than its stated maturity.     
   
The Portfolio also may invest in convertible securities rated below investment
grade but rated at least B by S&P or Moody's, comparably rated by another NRSRO
or, if unrated, determined by Mitchell Hutchins to be of comparable quality,
provided that the Portfolio will not do so if, as a result, more than 10% of
its total assets will be invested in non-investment grade convertible
securities. Securities rated below investment grade are commonly known as "junk
bonds."     
          
Money Market Instruments. The Portfolio may invest in high grade money market
instruments, which are debt securities with maturities of 13 months or less.
Such instruments will be chosen by Mitchell Hutchins based on its judgment of
their utility in furthering the Portfolio's investment objective. For a more
detailed description of the money market instruments in which the Portfolio's
invests, see the Statement of Additional Information.     
   
The Portfolio may invest in U.S. dollar-denominated securities of foreign
issuers that are traded on recognized U.S. exchanges or in the U.S. OTC market.
    
          
The GROWTH AND INCOME PORTFOLIO, under normal circumstances, invests at least
65% of its total assets in dividend-paying equity securities (common and
preferred stocks) believed by Mitchell Hutchins to have the potential for rapid
earnings growth. In managing the Portfolio, Mitchell Hutchins follows a
disciplined methodology under which stocks from a universe of approximately
2,000 medium to large capitalization companies are ranked utilizing
quantitative measures of value, earnings and price momentum in the context of
Mitchell Hutchins' economic forecast. Stocks are selected for the Portfolio
based on fundamental analysis of the highest ranking stocks. The Portfolio may
invest up to 35% of its total assets in equity securities not meeting the above
criteria, as well as     
 
                                     PW 13
<PAGE>
 
   
convertible securities, U.S. government securities, investment grade corporate
debt securities and money market securities. The Portfolio is permitted to
invest up to 10% of its total assets in convertible securities rated below
investment grade but no lower than B by S&P or Moody's, comparably rated by
another NRSRO or, if unrated, determined by Mitchell Hutchins to be of
comparable quality. The Portfolio will invest in instruments other than equity
securities when, in the opinion of Mitchell Hutchins, their projected total
return is equal to or greater than that of equity securities or when such
holdings might reduce the volatility of its portfolio. The Portfolio may invest
up to 25% of its total assets in U.S. dollar-denominated securities of foreign
issuers that are traded on recognized U.S. exchanges or in the U.S. OTC market.
       
Over the past 65 years, the total return of equity investments, as measured by
the Standard & Poor's 500 Composite Stock Price Index ("S&P 500"), has exceeded
the inflation rate, as measured by the Consumer Price Index, as well as total
return on long-term Treasury bonds, long-term corporate bonds and short-term
Treasury bills. However, year-to-year fluctuations in each of these indices and
instruments have been significant, and total return for the S&P 500 for some
periods has been negative. There can be no assurance that this trend will
continue, and the Portfolio performance may be better or worse than that of the
S&P 500.     
   
The GROWTH PORTFOLIO invests primarily in equity securities (common stock and
securities convertible into common stock) issued by companies that, in the
judgment of Mitchell Hutchins, have substantial potential for capital growth.
In selecting equity securities for investment by the Portfolio, Mitchell
Hutchins considers all of those factors it believes affect potential for
capital appreciation, including an issuer's current and projected revenues,
earnings, cash flow and assets, as well as general market conditions in
relevant industries. Under normal circumstances, at least 65% of the
Portfolio's total assets is invested in equity securities. For potential
capital appreciation (when, for instance, Mitchell Hutchins anticipates that
market interest rates may decline or credit factors or ratings affecting
particular issues may improve), the Portfolio's investment policies also permit
investment of up to 35% of the Portfolio's total assets in investment grade
debt securities. The Portfolio's investments in equity securities may include
investments of up to 35% of its total assets in convertible debt securities
that are rated below investment grade but no lower than B by S&P or Moody's,
comparably rated by another NRSRO or, if unrated, determined by Mitchell
Hutchins to be of comparable quality. Consistent with its investment objective,
the Portfolio may also invest up to 25% of its total assets in U.S. dollar-
denominated securities of foreign issuers if the securities are traded on
recognized U.S. exchanges or in the U.S. OTC market.     
 
The AGGRESSIVE GROWTH PORTFOLIO invests primarily in common stocks of U.S.
companies the assets and stock prices of which are expected by the Portfolio's
sub-adviser, Nicholas-Applegate Capital Management ("Nicholas-Applegate"), to
grow faster than the average rate of companies in the S&P 500. Companies in
which the Portfolio invests are diversified over a cross-section of industries
and may be growth companies, cyclical companies or companies believed to be
undergoing a basic change in operations or markets which, in the opinion of
Nicholas-Applegate, would result in a significant improvement in earnings. The
securities of such companies may be subject to more volatile market movements
than securities of larger, more established companies. The Portfolio is not
restricted to investments in companies of any particular size.
   
Under normal market conditions, the Aggressive Growth Portfolio invests at
least 75% of its total assets in common stocks. The Portfolio may invest up to
25% of its total assets in preferred and convertible securities issued by
similar growth companies, investment grade corporate debt securities, and
securities issued or guaranteed by the U.S. government, its agencies and
instrumentalities.     
 
 
                                     PW 14
<PAGE>
 
   
In making decisions with respect to common stocks for the Aggressive Growth
Portfolio, Nicholas-Applegate uses a proprietary investment methodology that
consists of investment techniques and processes designed to identify companies
with attractive earnings growth potential and to evaluate their investment
prospects.     
 
The Aggressive Growth Portfolio may invest up to 25% of its total assets in
U.S. dollar-denominated securities of foreign issuers that are traded on
recognized U.S. exchanges or in the U.S. OTC market.
   
The GLOBAL GROWTH PORTFOLIO invests primarily in the common stocks of companies
based in the United States, Europe, Japan and the Pacific Basin. Under normal
conditions, at least 65% of the Portfolio's total assets is invested in common
stocks and securities convertible into common stocks. The Portfolio will at all
times hold securities of issuers located in at least five countries and will
invest no more than 20% of its total assets in issuers located in any single
country outside the United States, except that the Portfolio may invest up to
35% of its total assets in issuers located in Japan. The Portfolio's sub-
adviser, GE Investment Management Incorporated ("GEIM"), seeks to identify
companies that have potential for growth and whose value has not been fully
recognized by the marketplace. GEIM concentrates primarily on medium to large-
size companies that it believes meet this undervalued growth criterion. The
Portfolio may also hold other types of securities, including non-convertible
investment grade corporate debt securities, government and money market
securities of U.S. and foreign issuers, and cash (foreign currencies or U.S.
dollars), in such proportions as, in the opinion of GEIM, prevailing market,
economic or political conditions warrant.     
       
              DESCRIPTION OF SECURITIES AND INVESTMENT TECHNIQUES
   
U.S. GOVERNMENT SECURITIES. The Strategic Fixed Income Portfolio, High Grade
Fixed Income Portfolio, Global Income Portfolio and Asset Allocation Portfolio
are authorized to invest a substantial portion of their assets in U.S.
government securities and the other Portfolios may invest in U.S. government
securities consistent with their investment objectives. The U.S. government
securities in which the Portfolios may invest include direct obligations of the
U.S. government (such as Treasury bills, notes and bonds) and obligations
issued by U.S. government agencies and instrumentalities, including securities
that are backed by the full faith and credit of the U.S. government (such as
Government National Mortgage Association ("Ginnie Mae") certificates) and
securities that are supported primarily or solely by the creditworthiness of
the issuer (such as securities of the Federal National Mortgage Association
("Fannie Mae"), the Federal Home Loan Mortgage Corporation ("Freddie Mac") and
the Tennessee Valley Authority). U.S. government securities are considered
among the most creditworthy of fixed income investments. Because of this, the
yields available from U.S. government securities are generally lower than the
yields available from corporate debt securities. Nevertheless, the values of
U.S. government securities (like those of fixed income securities generally)
will change as interest rates fluctuate.     
 
MORTGAGE- AND ASSET-BACKED SECURITIES. Mortgage-backed securities represent
direct or indirect participations in, or are secured by and payable from,
mortgage loans secured by real property and include single- and multi-class
pass-through securities and collateralized mortgage obligations. Multi-class
pass-through securities and collateralized mortgage obligations are
collectively referred to herein as CMOs. U.S. government mortgage-backed
securities include mortgage-backed securities issued or guaranteed as to the
payment of principal and interest (but not as to market value) by Ginnie Mae,
Fannie Mae or Freddie Mac. Other mortgage-backed securities are issued by
private issuers, generally originators of and investors in mortgage loans,
including savings associations, mortgage bankers, commercial banks, investment
bankers and special purpose entities (collectively, "Private Mortgage
Lenders"). Payments of principal and interest (but not the market value) of
such private mortgage-backed securities may be supported by pools of mortgage
loans or other mortgage-backed securities that are guaranteed, directly or
indirectly, by the U.S. government or one of its
 
                                     PW 15
<PAGE>
 
   
agencies or instrumentalities, or they may be issued without any government
guarantee of the underlying mortgage assets but with some form of non-
governmental credit enhancement.     
   
Asset-backed securities have structural characteristics similar to mortgage-
backed securities. However, the underlying assets are not first-lien mortgage
loans or interests therein, but include assets such as motor vehicle
installment sales contracts, other installment loan contracts, home equity
loans, leases of various types of real and personal property and receivables
from revolving credit (credit card) agreements. Such assets are securitized
through the use of trusts or special purpose corporations. Payments or
distributions of principal and interest on asset-backed securities may be
guaranteed up to certain amounts and for a certain time period by a letter of
credit or a pool insurance policy issued by a financial institution
unaffiliated with the issuer or other credit enhancements may be present.
Asset-backed securities are discussed further in the Statement of Additional
Information.     
 
The yield characteristics of mortgage- and asset-backed securities differ from
those of traditional debt securities. Among the major differences are that
interest and principal payments are made more frequently on mortgage- and
asset-backed securities, usually monthly, and that principal may be prepaid at
any time because the underlying mortgage loans or other assets generally may be
prepaid at any time. As a result, if a Portfolio purchases these securities at
a premium, a prepayment rate that is faster than expected will reduce yield to
maturity, while a prepayment rate that is slower than expected will have the
opposite effect of increasing yield to maturity. Conversely, if a Portfolio
purchases these securities at a discount, faster than expected prepayments will
increase, while slower than expected prepayments will reduce, yield to
maturity. Amounts available for reinvestment are likely to be greater during a
period of declining interest rates and, as a result, are likely to be
reinvested at lower interest rates than during a period of rising interest
rates. Accelerated prepayments on securities purchased by a Portfolio at a
premium also impose a risk of loss of principal because the premium may not
have been fully amortized at the time the principal is repaid in full. The
market for privately issued mortgage- and asset-backed securities is smaller
and less liquid than the market for mortgage-backed securities of government
issuers.
 
CMO classes may be specially structured in a manner that provides any of a wide
variety of investment characteristics, such as yield, effective maturity and
interest rate sensitivity. As market conditions change, however, and
particularly during periods of rapid or unanticipated changes in market
interest rates, the attractiveness of the CMO classes and the ability of the
structure to provide the anticipated investment characteristics may be
significantly reduced. These changes can result in volatility in the market
value, and in some instances reduced liquidity, of the CMO class.
 
The rate of interest payable on CMO classes may be set at levels that are
either above or below market rates at the time of issuance, so that the
securities will be sold at a substantial premium to, or at a discount from, par
value. In the most extreme case, one class will be entitled to receive all or a
portion of the interest but none of the principal from the underlying mortgage
assets (the interest-only or "IO" class) and one class will be entitled to
receive all or a portion of the principal but none of the interest (the
principal-only or "PO" class). IOs and POs may also be created from mortgage-
backed securities that are not CMOs. The yields on IOs, POs and other mortgage-
backed securities that are purchased at a substantial premium or discount
generally are extremely sensitive to the rate of principal payments (including
prepayments) on the underlying mortgage assets. If the mortgage assets
underlying an IO experience greater than anticipated principal prepayments, an
investor may fail to recoup fully his or her initial investment even if the
security is government issued or guaranteed or is rated AAA or the equivalent.
 
Some CMO classes are structured to pay interest at rates that are adjusted in
accordance with a formula, such as a multiple or fraction of the change in a
specified interest rate index, so as to pay at a rate that will be attractive
in certain interest rate environments but not in others. For example, an
 
                                     PW 16
<PAGE>
 
inverse floating rate CMO class pays interest at a rate that increases as a
specified interest rate index decreases but decreases as that index increases.
For other CMO classes, the yield may move in the same direction as market
interest rates--i.e. the yield may increase as rates increase and decrease as
rates decrease--but may do so more rapidly or to a greater degree. The market
value of such securities generally is more volatile than that of a fixed rate
obligation. Such interest rate formulas may be combined with other CMO
characteristics. For example, a CMO class may be an "inverse IO," on which the
holders are entitled to receive no payments of principal and are entitled to
receive interest at a rate that will vary inversely with a specified index or a
multiple thereof.
 
During 1994, the value and liquidity of many mortgage-backed securities
declined sharply due primarily to increases in interest rates. There can be no
assurance that such declines will not recur. The market value of certain
mortgage-backed securities, including IO and PO classes of mortgage-backed
securities and inverse floating rate securities, can be extremely volatile and
these securities may become illiquid. Mitchell Hutchins or the applicable sub-
adviser seeks to manage each Portfolio so that its volatility, taken as a
whole, is consistent with the Portfolio's investment objective. If Mitchell
Hutchins or the applicable sub-adviser incorrectly forecasts interest rate
changes or other factors that may affect the volatility of securities held by
the Portfolio, the Portfolio's ability to meet its investment objective may be
reduced.
 
See Appendix A to this Prospectus for more information concerning the types of
mortgage-backed securities in which the Portfolios may invest.
   
FOREIGN SECURITIES. The Global Growth and Global Income Portfolios invest a
substantial portion of their assets in foreign securities and the Strategic
Fixed Income Portfolio may invest up to 10% of its assets in securities
denominated in foreign currencies and another 10% of its assets in Yankee and
Eurodollar bonds combined. In addition, the Growth, Growth and Income, High
Grade Fixed Income and Aggressive Growth Portfolios may each invest a portion
of its total assets in U.S. dollar-denominated securities of foreign issuers if
such securities are traded on recognized U.S. exchanges or in the U.S. OTC
market and the Asset Allocation Portfolio also may invest in such securities.
Accordingly, an investment in any of these Portfolios involves risks relating
to political, social and economic developments abroad, as well as risks
resulting from the differences between the regulations to which U.S. and
foreign issuers and markets are subject. These risks are greater with respect
to the Global Growth and Global Income Portfolios because a substantially
greater portion of their assets may be invested in such securities and because
these Portfolios may invest substantially in foreign securities that are
denominated in foreign currencies and traded outside the U.S. securities
markets. These risks may include expropriation, confiscatory taxation,
withholding taxes on dividends and interest, limitations on the use or transfer
of Portfolio assets and political or social instability or diplomatic
developments. Moreover, individual foreign economies may differ favorably or
unfavorably from the U.S. economy in such respects as growth of gross national
product, rate of inflation, capital reinvestment, resource self-sufficiency and
balance of payments position. Securities of many foreign companies may be less
liquid and their prices more volatile than securities of comparable U.S.
companies. While the Portfolios generally invest only in securities that are
traded on recognized exchanges or in OTC markets, from time to time foreign
securities may be difficult to liquidate rapidly without significantly
depressing the price of such securities. There may be less publicly available
information concerning foreign issuers of securities held by these Portfolios
than is available concerning U.S. companies. Transactions in foreign securities
may be subject to less efficient settlement practices. Foreign securities
trading practices, including those involving securities settlement where
Portfolio assets may be released prior to receipt of payment, may expose a
Portfolio to increased risk in the event of a failed trade or the insolvency of
a foreign broker-dealer. Legal remedies for defaults and disputes may have to
be pursued in foreign courts, whose procedures differ substantially from those
of U.S. courts.     
 
Because foreign securities ordinarily are denominated in currencies other than
the U.S. dollar (as are some securities of U.S. issuers), changes in foreign
currency exchange rates will affect a
 
                                     PW 17
<PAGE>
 
Portfolio's net asset value, the value of dividends and interest earned, gains
and losses realized on the sale of securities and net investment income and
capital gain, if any, to be distributed to shareholders by the Portfolio. If
the value of a foreign currency rises against the U.S. dollar, the value of a
Portfolio's assets denominated in that currency will increase; correspondingly,
if the value of a foreign currency declines against the U.S. dollar, the value
of a Portfolio's assets denominated in that currency will decrease. The
exchange rates between the U.S. dollar and other currencies are determined by
supply and demand in the currency exchange markets, international balances of
payments, speculation and other economic and political conditions. In addition,
some foreign currency values may be volatile and there is the possibility of
governmental controls on currency exchange or governmental intervention in
currency markets. Any of these factors could adversely affect these Portfolios.
   
The costs attributable to foreign investing that the Global Growth, Global
Income and Strategic Fixed Income Portfolios must bear frequently are higher
than those attributable to domestic investing. For example, the costs of
maintaining custody of securities in foreign countries exceed custodian costs
for domestic securities.     
   
The Strategic Fixed Income, Global Income and the Global Growth Portfolios may
invest in securities of issuers located in emerging market countries. The risks
of investing in foreign securities may be greater with respect to securities of
issuers in, or denominated in the currencies of, emerging market countries. The
economies of emerging market countries generally are heavily dependent upon
international trade and, accordingly, have been and may continue to be
adversely affected by trade barriers, exchange controls, managed adjustments in
relative currency values and other protectionist measures imposed or negotiated
by the countries with which they trade. These economies also have been and may
continue to be adversely affected by economic conditions in the countries with
which they trade. Many emerging market countries have experienced substantial,
and in some periods extremely high, rates of inflation for many years.
Inflation and rapid fluctuations in inflation rates have had and may continue
to have very negative effects on the economies and securities markets of
certain emerging market countries. The securities markets of emerging market
countries are substantially smaller, less developed, less liquid and more
volatile than the securities markets of the U.S. and other developed countries.
Disclosure and regulatory standards in many respects are less stringent in
emerging market countries than in the U.S. and other major markets. There also
may be a lower level of monitoring and regulation of emerging markets and the
activities of investors in such markets, and enforcement of existing
regulations may be extremely limited. Investing in local markets, particularly
in emerging market countries, may require these Portfolios to adopt special
procedures, seek local government approvals or take other actions, each of
which may involve additional costs to the Portfolios. Certain emerging market
countries may also restrict investment opportunities in issuers in industries
deemed important to national interests.     
 
FOREIGN GOVERNMENT SECURITIES. Foreign government securities generally consist
of obligations supported by national, state or provincial governments or
similar political subdivisions. Foreign government securities also include debt
obligations of supranational entities, which include international
organizations designated or supported by governmental entities to promote
economic reconstruction or development, international banking institutions and
related government agencies. Examples include the World Bank, the European Coal
and Steel Community, the Asian Development Bank and the InterAmerican
Development Bank.
 
Foreign government securities also include debt securities of "quasi-
governmental agencies" and debt securities denominated in multinational
currency units of an issuer (including supranational issuers). An example of a
multinational currency unit is the European Currency Unit ("ECU"). An ECU
represents specified amounts of the currencies of certain member states of the
European Union. Debt securities of quasi-governmental agencies are issued by
entities owned by either a national, state or equivalent government or are
obligations of a political unit that is not backed by the national
 
                                     PW 18
<PAGE>
 
government's full faith and credit and general taxing powers. Foreign
government securities also include mortgage-related securities issued or
guaranteed by national, state or provincial governmental instrumentalities,
including quasi-governmental agencies.
 
FOREIGN BANK AND FOREIGN BRANCH INSTRUMENTS. The Money Market Portfolio may
invest in obligations of domestic branches of foreign banks and foreign
branches of domestic banks. The Global Income Portfolio may invest in these
instruments and also in obligations of bank holding companies and foreign
banks. The other Portfolios may invest in such securities consistent with their
investment objectives and policies. Such investments may involve risks that are
different from investments in obligations of U.S. branches of domestic banks.
These risks may include future unfavorable political and economic developments,
possible withholding taxes, seizure of foreign deposits, currency controls,
interest limitations or other governmental restrictions that might affect the
payment of principal or interest on the securities held by a Portfolio.
Additionally, there may be less publicly available information about foreign
banks and foreign branches of U.S. banks, as these institutions may not be
subject to the same regulatory requirements as domestic banks.
   
DEBT SECURITIES. The Strategic Fixed Income, Global Income, Asset Allocation,
Growth and Income, Growth, Aggressive Growth and Global Growth Portfolios all
may invest a substantial portion of their assets in debt securities rated
within any one of the four highest grades assigned by S&P or Moody's or
assigned a comparable rating by another NRSRO (commonly referred to as
"investment grade debt securities"). Debt securities rated Baa by Moody's or
BBB by S&P are investment grade, although Moody's considers securities rated
Baa to have speculative characteristics. Changes in economic conditions or
other circumstances are more likely to lead to a weakened capacity for such
securities to make principal and interest payments than is the case for higher
grade debt securities. The Asset Allocation, Growth and Income and Growth
Portfolios may invest in non-investment grade convertible debt securities. The
Strategic Fixed Income may invest in non-investment grade convertible and non-
convertible debt securities, and Global Income Portfolio may invest in non-
investment grade sovereign debt securities. Debt securities rated below
investment grade are deemed by these NRSROs to be predominantly speculative
with respect to the issuer's capacity to pay interest and repay principal and
may involve major risk exposures to adverse conditions. Such securities are
commonly referred to as "junk bonds." In the event that, due to the downgrade
of one or more debt securities, a Portfolio holds securities rated below
investment grade in an amount in excess of the percentage permitted under these
investment policies, the Portfolio will engage in an orderly disposition of
these securities to the extent necessary to reduce the Portfolio's holdings to
the specified percentage. All Portfolios are permitted to purchase debt
securities that are not rated by S&P, Moody's or another NRSRO but that
Mitchell Hutchins or the applicable sub-adviser determines to be of comparable
quality to that of rated securities in which such Portfolio may invest. Such
securities are included in the computation of any percentage limitations
applicable to the comparable rated securities.     
 
The market value of debt securities generally varies inversely with interest
rate changes. Ratings of debt securities represent the rating agency's opinion
regarding their quality, are not a guarantee of quality and may be reduced
after a Portfolio has acquired the security. Mitchell Hutchins or the
applicable sub-adviser will consider such an event in determining whether the
Portfolio should continue to hold the security but the Portfolio is not
required to dispose of it. Credit ratings attempt to evaluate the safety of
principal and interest payments and do not evaluate the risks of fluctuations
in market value. Also, rating agencies may fail to make timely changes in
response to subsequent events, so that an issuer's financial condition may be
better or worse than the rating indicates.
 
Lower rated debt securities generally offer a higher current yield than that
available from higher grade issues, but they involve higher risks, in that they
are especially subject to adverse changes in general economic conditions and in
the industries in which the issuers are engaged, to changes in the
 
                                     PW 19
<PAGE>
 
financial condition of the issuers and to price fluctuation in response to
changes in interest rates. During periods of economic downturn or rising
interest rates, highly leveraged issuers may experience financial stress which
could adversely affect their ability to make payments of principal and interest
and increase the possibility of default. In addition, such issuers may not have
more traditional methods of financing available to them, and may be unable to
repay debt at maturity by refinancing. The risk of loss due to default by such
issuers is significantly greater because such securities frequently are
unsecured and subordinated to the prior payment of senior indebtedness.
 
The market for lower rated securities has expanded rapidly in recent years, and
its growth paralleled a long economic expansion. In the past, the prices of
many lower rated debt securities declined substantially, reflecting an
expectation that many issuers of such securities might experience financial
difficulties. As a result, the yields on lower rated debt securities rose
dramatically, but such higher yields did not reflect the value of the income
stream that holders of such securities expected, but rather the risk that
holders of such securities could lose a substantial portion of their value as a
result of the issuers' financial restructuring or default. There can be no
assurance that such declines will not recur. The market for lower rated debt
securities generally is thinner and less active than that for higher quality
securities, which may limit a Portfolio's ability to sell such securities at
fair value in response to changes in the economy or the financial markets.
Adverse publicity and investor perceptions, whether or not based on fundamental
analysis, may also decrease the values and liquidity of lower rated securities,
especially in a thinly traded market.
   
DURATION. Duration is a measure of the expected life of a fixed income security
that was developed as a more precise alternative to the concept of "term to
maturity." Duration incorporates a bond's yield, coupon interest payments,
final maturity and call features into one measure. Duration is one of the
fundamental tools used by the sub-adviser in portfolio selection for the
Strategic Fixed Income Portfolio.     
   
Traditionally, a debt security's "term to maturity" has been used as a proxy
for the sensitivity of the security's price to changes in interest rates (which
is the "interest rate risk" or "volatility" of the security). However, "term to
maturity" measures only the time until a debt security provides its final
payments, taking no account of the pattern of the security's payments prior to
maturity. Duration is a measure of the expected life of a fixed income security
on a present value basis. Duration takes the length of the time intervals
between the present time and the time that the interest and principal payments
are scheduled or, in the case of a callable bond, expected to be received, and
weights them by the present values of the cash to be received at each future
point in time. For any fixed income security with interest payments occurring
prior to the payment of principal, duration is always less than maturity. In
general, all other things being equal, the lower the stated or coupon rate of
interest of a fixed income security, the longer the duration of the security;
conversely, the higher the stated or coupon rate of interest of a fixed income
security, the shorter the duration of the security.     
          
Futures, options and options on futures have duration which in general, are
closely related to the duration of the securities which underlie them. Holding
long futures or call option positions (backed by a segregated account of cash
and cash equivalents) will lengthen a Portfolio's duration by approximately the
same amount that selling an equivalent amount of the underlying securities
would.     
   
Short futures or put option positions have durations roughly equal to the
negative duration of the securities that underlie these positions, and have the
effect of reducing portfolio duration by approximately the same amount that
selling an equivalent amount of the underlying securities would.     
   
There are some situations where even the standard duration calculation does not
properly reflect the interest rate exposure of a security. For example,
floating and variable rate securities often have     
 
                                     PW 20
<PAGE>
 
   
final maturities of ten or more years; however, their interest rate exposure
corresponds to the frequency of the coupon reset. Another example where the
interest rate exposure is not properly captured by duration is the case of
mortgage pass-through securities. The stated final maturity of such securities
is generally 30 years, but current prepayment rates are more critical in
determining the securities' interest rate exposure. In these and other similar
situations, the sub-adviser will use more sophisticated analytical techniques
that incorporate the economic life of a security into the determination of its
interest rate exposure.     
   
CONVERTIBLE SECURITIES. A convertible security is a bond, debenture, note,
preferred stock or other security that may be converted into or exchanged for a
prescribed amount of common stock of the same or a different issuer within a
particular period of time at a specified price or formula. A convertible
security entitles the holder to receive interest paid or accrued on debt or
dividends paid on preferred stock until the convertible security matures or is
redeemed, converted or exchanged. Convertible securities have unique investment
characteristics in that they generally (1) have higher yields than common
stocks, but lower yields than comparable non-convertible securities, (2) are
less subject to fluctuation in value than the underlying stock because they
have fixed income characteristics, and (3) provide the potential for capital
appreciation if the market price of the underlying common stock increases.
While no securities investment is without some risk, investments in convertible
securities generally entail less risk than the issuer's common stock, although
the extent to which such risk is reduced depends in large measure upon the
degree to which the convertible security sells above its value as a fixed
income security.     
   
ZERO COUPON AND PAYMENT-IN KIND SECURITIES. Strategic Fixed Income, High Grade
Fixed Income, Global Income and Asset Allocation Portfolios may invest in
certain zero coupon securities that are "stripped" U.S. Treasury notes and
bonds. The Strategic Fixed Income Portfolio also may invest in zero coupon
securities of corporate issuers and other securities that are issued with
original issue discount ("OID") and payment-in-kind ("PIK") securities. Federal
tax law requires that a holder of a security with OID accrue a portion of the
OID on the security as income each year, even though the holder may receive no
interest payment on the security during the year. Accordingly, although the
investing Portfolio will receive no payments on its zero coupon securities
prior to their maturity or disposition, it will have income attributable to
such securities. Similarly, while PIK securities may pay interest in the form
of additional securities rather than cash, that interest must be included in
the annual income of Strategic Fixed Income Portfolio.     
   
Companies such as the Portfolios, which seek to qualify for pass-through
federal income tax treatment as regulated investment companies ("RIC"), must
distribute substantially all of their net investment income each year,
including non-cash income. Accordingly, each Portfolio will be required to
include in its dividends an amount equal to the income attributable to its zero
coupon, other OID and PIK securities. Those dividends will be paid from the
cash assets of a Portfolio or by liquidation of portfolio securities, if
necessary, at a time when the Portfolio otherwise might not have done so. Zero
coupon and PIK securities usually trade at a substantial discount from their
face or par value and will be subject to greater fluctuations of market value
in response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.     
   
LENDING OF PORTFOLIO SECURITIES. Each Portfolio (other than the Money Market
Portfolio) is authorized to lend up to 10% (33 1/3% for Strategic Fixed Income
Portfolio) of the total value of its portfolio securities to broker-dealers or
institutional investors that Mitchell Hutchins or the applicable sub-adviser
deems qualified. Lending securities enables a Portfolio to earn additional
income, but could result in a loss or delay in recovering the Portfolio's
securities.     
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. Each Portfolio may purchase
securities on a "when-issued" basis or may purchase or sell securities for
delayed delivery. In when-issued or delayed delivery transactions, delivery of
the securities occurs beyond normal settlement periods, but a
 
                                     PW 21
<PAGE>
 
Portfolio would not pay for such securities or start earning interest on them
until they are delivered. However, when a Portfolio purchases securities on a
when-issued or delayed delivery basis, it immediately assumes the risks of
ownership, including the risk of price fluctuation. Failure by a counter party
to deliver a security purchased on a when-issued or delayed delivery basis may
result in a loss or missed opportunity to make an alternative investment.
Depending on market conditions, a Portfolio's when-issued and delayed-delivery
purchase commitments could cause its net asset value per share to be more
volatile, because such securities may increase the amount by which the
Portfolio's total assets, including the value of when-issued and delayed-
delivery securities held by the Portfolio, exceed its net assets.
 
REPURCHASE AGREEMENTS. Each Portfolio may enter into repurchase agreements.
Repurchase agreements are transactions in which a Portfolio purchases
securities from a bank or recognized securities dealer and simultaneously
commits to resell the securities to the bank or dealer at an agreed-upon date
and price reflecting a market rate of interest unrelated to the coupon rate or
maturity of the purchased securities. Repurchase agreements carry certain risks
not associated with direct investments in securities, including possible
decline in the market value of the underlying securities and delays and costs
to a Portfolio if the other party to the repurchase agreement becomes
insolvent, each Portfolio intends to enter into repurchase agreements only with
banks and dealers in transactions believed by Mitchell Hutchins or the
applicable sub-adviser to present minimal credit risks in accordance with
guidelines established by the Fund's board of trustees.
   
REVERSE REPURCHASE AGREEMENTS AND DOLLAR ROLLS. The Strategic Fixed Income and
Global Income Portfolio may enter into reverse repurchase agreements with banks
and broker-dealers. Such agreements involve the sale of securities held by the
Portfolio subject to the Portfolio's agreement to repurchase the securities at
an agreed-upon date and price. Such agreements are considered to be borrowings
and for the Global Income Portfolio may be entered into only for temporary
purposes. The market value of securities sold under reverse repurchase
agreements typically is greater than the proceeds of the sale, and accordingly,
the market value of the securities sold is likely to be greater than the value
of the securities in which the Portfolio invests those proceeds. Thus, reverse
repurchase agreements involve the risk that the buyer of the securities sold by
the Portfolio might be unable to deliver them when the Portfolio seeks to
repurchase. In the event the buyer of securities under a reverse repurchase
agreement files for bankruptcy or becomes insolvent, such buyer or its trustee
or receiver may receive an extension of time to determine whether to enforce
the Portfolio's obligation to repurchase the securities and the Portfolio's use
of the proceeds of the reverse repurchase agreement may effectively be
restricted pending such decision.     
   
The Strategic Fixed Income may enter into dollar rolls, in which the Portfolio
sells mortgage-backed or other securities for delivery in the current month and
simultaneously contracts to repurchase substantially similar securities on a
specified future date. In the case of dollar rolls involving mortgage-backed
securities, the mortgage-backed securities that are repurchased will be of the
same type, and will have the same interest rate and maturity, as those sold but
generally will be supported by different pools of mortgages with substantially
similar prepayment characteristics. The Portfolio forgoes principal and
interest paid during the roll period on the securities sold in a dollar roll,
but the Portfolio is compensated by the difference between the current sales
price and the lower price for the future purchase as well as by any interest
earned on the proceeds of the securities sold. The Portfolio also could be
compensated through the receipt of fee income equivalent to a lower forward
price.     
   
The dollar rolls and reverse repurchase agreements entered into by the
Strategic Fixed Income Portfolio normally will be arbitrage transactions in
which the Portfolio will invest the proceeds of the dollar roll or reverse
repurchase agreement in high quality securities that mature on or before the
settlement date on the related dollar roll or reverse repurchase agreement or
in repurchase     
 
                                     PW 22
<PAGE>
 
   
agreements that mature in no more than seven days. Because the Portfolio will
invest the proceeds of its borrowings and will earn interest on those
investments, these transactions involve leverage. However, because the
borrowing proceeds are invested in short-term, high quality debt securities or
repurchase agreements, as described above, Mitchell Hutchins or the applicable
sub-adviser believes that such arbitrage transactions do not present the risks
to the Portfolio that are associated with other types of leverage.     
   
Dollar rolls and reverse repurchase agreements are considered to be borrowings
and, accordingly, are subject to the respective Portfolio's limitations on
borrowings, which restricts the aggregate of such transactions (plus any other
borrowings) to 10% of the Global Income Portfolio's total assets (33 1/3% for
Strategic Fixed Income Fund). A Portfolio will not enter into dollar rolls or
reverse repurchase agreements, other than in arbitrage transactions as
described above, in an aggregate amount in excess of 5% of the Portfolio's
total assets. The Strategic Fixed Income Portfolio has no present intention to
enter into dollar rolls other than in such arbitrage transactions, and neither
Portfolio has any present intention to enter into reverse repurchase agreements
other than in such arbitrage transactions or for temporary or emergency
purposes.     
   
HEDGING AND RELATED INCOME STRATEGIES. Except for the Money Market and Asset
Allocation Portfolios, each Portfolio may use options (both exchange-traded and
OTC) and futures contracts to attempt to enhance income and may attempt to
reduce the overall risk of its investments (hedge) by using options and futures
contracts, although the High Grade Fixed Income and Aggressive Growth
Portfolios have no intention of doing so during the coming year. The Strategic
Fixed Income, Global Income and Global Growth Portfolios may also use forward
currency contracts. A Portfolio's ability to use these strategies may be
limited by market conditions, regulatory limits and tax considerations.
Appendix B to this Prospectus describes the hedging instruments that the
Portfolios may use. The Statement of Additional Information contains further
information on these strategies.     
   
Each Portfolio eligible to use hedging and related income strategies may write
(sell) covered call and put options, buy call and put options on securities in
which it is authorized to invest and on stock indexes, sell stock index or
interest rate futures contracts and buy put and call options and write covered
call options on such futures contracts. The Strategic Fixed Income, Global
Income and Global Growth Portfolios each may write covered call options and buy
put and call options on foreign currencies, buy or sell foreign currency
futures contracts, buy put and call options and write covered call options on
such contracts. These Portfolios may enter into forward currency contracts for
the purchase or sale of a specified currency at a specified future date either
with respect to specific transactions or with respect to portfolio positions.
For example, when Mitchell Hutchins or the applicable sub-adviser anticipates
making a currency exchange transaction in connection with the purchase or sale
of a security, a Portfolio may enter into a forward contract in order to set
the exchange rate at which the transaction will be made. A Portfolio also may
enter into a forward contract to sell an amount of a foreign currency
approximating the value of some or all of the Portfolio's securities positions
denominated in such currency. A Portfolio may use forward contracts in one
currency or a basket of currencies to hedge against fluctuations in the value
of another currency when Mitchell Hutchins or the applicable sub-adviser
anticipates that there will be a correlation between the two and may use
forward currency contracts to shift a Portfolio's exposure to foreign currency
fluctuations from one country to another. The purpose of entering into these
contracts is to minimize the risk to a Portfolio from adverse changes in the
relationship between the U.S. dollar and foreign currencies.     
   
The Strategic Fixed Income and Global Income Portfolios may enter into interest
rate protection transactions, including interest rate swaps and interest rate
caps, collars and floors, for hedging purposes. For example, each Portfolio may
enter into interest rate protection transactions to preserve a return or spread
on a particular investment or portion of its portfolio or to protect against
any increase in the price of securities the Portfolio anticipates purchasing at
a later date. The Portfolio     
 
                                     PW 23
<PAGE>
 
   
will enter into interest rate protection transactions only with banks and
recognized securities dealers believed by Mitchell Hutchins or the applicable
sub-adviser to present minimal credit risks in accordance with guidelines
established by the Fund's board of trustees.     
 
A Portfolio might not employ any of the strategies described above, and there
can be no assurance that any strategy used will succeed. If Mitchell Hutchins
or the applicable sub-adviser incorrectly forecasts interest rates, market
values or other economic factors for a Portfolio, the Portfolio would be in a
better position had it not hedged at all. The use of these strategies involves
certain special risks, including (1) the fact that skills needed to use hedging
instruments are different from those needed to select the Portfolios'
securities, (2) possible imperfect correlation, or even no correlation, between
price movements of hedging instruments and price movements of the investments
being hedged, (3) the fact that, while hedging strategies can reduce the risk
of loss, they can also reduce the opportunity for gain, or even result in
losses, by offsetting favorable price movements in hedged investments and (4)
the possible inability of a Portfolio to purchase or sell a portfolio security
at a time that otherwise would be favorable for it to do so, or the possible
need for a Portfolio to sell a portfolio security at a disadvantageous time,
due to the need for the Portfolio to maintain "cover" or to segregate
securities in connection with hedging transactions and the possible inability
of a Portfolio to close out or to liquidate its hedged position.
 
New financial products and risk management techniques continue to be developed.
Each Portfolio may use these instruments and techniques to the extent
consistent with its investment objectives and regulatory and federal tax
considerations.
   
ILLIQUID SECURITIES. Each Portfolio may invest up to 10% of its net assets (15%
for the Strategic Fixed Income and Aggressive Growth Portfolios) in illiquid
securities, including certain cover for OTC options, repurchase agreements with
maturities in excess of seven days and securities whose disposition is
restricted under the federal securities laws (other than "Rule 144A" securities
which Mitchell Hutchins has determined to be liquid under procedures approved
by the Fund's board of trustees). Rule 144A establishes a "safe harbor" from
the registration requirements of the Securities Act of 1933 ("1933 Act").
Institutional markets for restricted securities have developed as a result of
Rule 144A, providing both readily ascertainable values for restricted
securities and the ability to liquidate an investment to satisfy share
redemption orders. An insufficient number of qualified institutional buyers
interested in purchasing Rule 144A-eligible restricted securities held by a
Portfolio, however, could affect adversely the marketability of such portfolio
securities and the Portfolio might be unable to dispose of such securities
promptly or at favorable prices.     
   
The Strategic Fixed Income Portfolio may invest in secured or unsecured fixed
or floating rate loans ("Loans") arranged through private negotiations between
a borrowing corporation and one or more financial institutions ("Lenders"). The
Portfolio's investments in Loans are expected in most instances to be in the
form of participations ("Participations") and assignments ("Assignments") of
all or a portion of Loans from third parties. Participations typically result
in the Portfolio's having a contractual relationship only with the Lender, not
with the borrower. The Portfolio has the right to receive payments of
principal, interest and any fees to which it is entitled only from the lender
selling the Participation and only upon receipt by the Lender of the payments
from the borrower. In connection with purchasing Participations, the Portfolio
generally has no direct right to enforce compliance by the borrower with the
terms of the loan agreement relating to the Loan, nor any rights of set-off
against the borrower, and the Portfolio may not benefit directly from any
collateral supporting the Loan in which it has purchased the Participation. As
a result, the Portfolio assumes the credit risk of both the borrower and the
Lender that is selling the Participation. In the event of the insolvency of the
Lender selling a Participation, the Portfolio may be treated as a general
creditor of the Lender and may not benefit from any set-off between the Lender
and the borrower. The Portfolio will acquire Participations only if the lender
interpositioned between the Portfolio and the borrower is determined by the
sub-adviser to be creditworthy.     
 
                                     PW 24
<PAGE>
 
   
When the Strategic Fixed Income Portfolio purchases Assignments from Lenders,
it acquires direct rights against the borrower on the Loan. However, because
Assignments are arranged through private negotiations between potential
assignees and assignors, the rights and obligations acquired by the Portfolio
as the purchaser of an Assignment may differ from, and be more limited than,
those held by the assigning Lender.     
   
Assignments and Participations are generally not registered under the 1933 Act
and thus are subject to the Strategic Fixed Income Portfolio's limitation to
15% of its net assets with respect to its investments in illiquid securities.
Because there is no liquid market for these securities, the Portfolio
anticipates that these securities could be sold only to a limited number of
institutional investors. The lack of a liquid secondary market will have an
adverse impact of the value of these securities and on the Portfolio's ability
to dispose of particular Assignments and Participations when necessary to meet
the Portfolio's liquidity needs or in response to a specific economic event,
such as a deterioration in the creditworthiness of the borrower.     
 
PORTFOLIO TURNOVER. The portfolio turnover rate may vary greatly from year to
year and will not be a limiting factor when Mitchell Hutchins or the applicable
sub-adviser deems portfolio changes appropriate. A higher turnover rate may
involve correspondingly greater transaction costs, which will be borne directly
by the affected Portfolio and may increase the potential for short-term capital
gains.
          
OTHER INFORMATION. When Mitchell Hutchins or the applicable sub-adviser
believes unusual circumstances warrant a defensive posture, each Portfolio
temporarily may commit all or any portion of its assets to cash, U.S.
government securities or money market instruments, including repurchase
agreements. The Strategic Fixed Income, Global Income and Global Growth
Portfolios may hold cash in U.S. dollars or foreign currencies and money market
instruments of U.S. or foreign issuers, including instruments backed by the
U.S. or foreign governments, their agencies or instrumentalities and repurchase
agreements secured thereby. Each Portfolio may borrow money for temporary
purposes but not in excess of 10% of its total assets (33 1/3% for the
Strategic Fixed Income and High Grade Fixed Income Portfolios and 20% for the
Aggressive Growth Portfolio).     
 
Each Portfolio's investment objective and certain investment limitations, as
described in the Statement of Additional Information, are fundamental policies
that may not be changed without shareholder approval. All other investment
policies may be changed by the Fund's board of trustees without shareholder
approval.
 
                      PURCHASES, REDEMPTIONS AND EXCHANGES
 
Shares of the Portfolios are offered only to the insurance company separate
accounts that fund the Contracts. All such shares may be purchased or redeemed
by the separate accounts without any sales or redemption charge at net asset
value. Proceeds from redemptions in any of the Portfolios will be paid on or
before the seventh day following the request for redemption by a Contract
holder.
 
A separate account may exchange shares of one Portfolio for shares of another
Portfolio at their relative net asset values per share.
 
             DIVIDENDS, OTHER DISTRIBUTIONS AND FEDERAL INCOME TAX
 
DIVIDENDS AND OTHER DISTRIBUTIONS. With the exception of the Money Market
Portfolio, each Portfolio distributes all of its net investment income as
dividends to its shareholders shortly after the close of the Fund's fiscal year
on December 31. At the same time, those Portfolios also distribute
 
                                     PW 25
<PAGE>
 
to their shareholders all of their net short-term capital gain and their net
capital gain (the excess of net long-term capital gain over net short-term
capital loss) and any net gains from foreign currency transactions. Those
Portfolios may make a second distribution of net investment income, net short-
term capital gain, net capital gain and net gains from foreign currency
transactions if necessary to avoid income tax.
 
The Money Market Portfolio declares as dividends on each Business Day all of
its net investment income, payable to shareholders of record as of the close of
regular trading on the New York Stock Exchange ("NYSE") (currently 4:00 p.m.,
eastern time) on the preceding Business Day; those dividends are paid monthly.
A "Business Day" is any day, Monday through Friday, on which the NYSE is open
for business. Net investment income of the Portfolio consists of accrued
interest and earned discount (including both original issue and market
discounts), less amortization of market premium and applicable expenses. Net
investment income is calculated and dividends are declared immediately prior to
the determination of net asset value per share. The Portfolio generally
distributes to its shareholders any net short-term capital gain annually after
the end of its fiscal year on December 31 but may make more frequent
distributions of that gain if necessary to maintain its net asset value per
share at $1.00 or to avoid income tax. The Portfolio does not expect to realize
long-term capital gain and thus does not anticipate any distributions of net
capital gain.
 
Dividends and capital gain distributions from a Portfolio are paid in
additional shares of that Portfolio at net asset value per share, unless the
Fund's transfer agent is instructed otherwise. See the applicable Contract
prospectus for information regarding the federal income tax treatment of
distributions to the separate accounts.
 
FEDERAL INCOME TAX. Each Portfolio intends to continue to qualify for treatment
as a regulated investment company ("RIC") under Subchapter M of the Internal
Revenue Code so that it will be relieved of federal income tax on that part of
its investment company taxable income (consisting generally of net investment
income, net gains from certain foreign currency transactions and net short-term
capital gain) and net capital gain that is distributed to its shareholders.
 
Dividends and other distributions declared by a Portfolio in October, November
or December of any year and payable to shareholders of record on a date in any
of those months will be deemed to have been paid by the Portfolio and received
by the shareholders on December 31 of that year if the distributions are paid
by the Portfolio during the succeeding January.
 
Portfolio shares are offered only to insurance company separate accounts that
fund variable annuity and variable life insurance contracts. Under the Internal
Revenue Code, no tax is imposed on an insurance company with respect to income
of a qualifying separate account properly allocable to the value of eligible
variable annuity or variable life insurance contracts. See the applicable
Contract prospectus for a discussion of the federal income tax status of (1)
the separate accounts that purchase and hold shares of the Portfolios and (2)
the holders of Contracts funded through those accounts.
   
Each Portfolio intends to continue to comply with the diversification
requirements imposed by section 817(h) of the Internal Revenue Code and the
regulations thereunder. These requirements, which are in addition to the
diversification requirements imposed on the Portfolios by the 1940 Act and
Subchapter M, place certain limitations on the assets of each separate
account--and, because section 817(h) and those regulations treat the assets of
each Portfolio as assets of the related separate account, of each Portfolio--
that may be invested in securities of a single issuer. Specifically, the
regulations provide that, except as permitted by the "safe harbor" described
below, as of the end of each calendar quarter or within 30 days thereafter no
more than 55% of the total assets of a Portfolio may be represented by any one
investment, no more than 70% by any two investments, no more than 80% by any
three investments and no more than 90% by any four investments. For this
purpose, all securities of the same issuer are considered a single investment,
and each U.S. government agency     
 
                                     PW 26
<PAGE>
 
   
and instrumentality is considered a separate issuer. Section 817(h) provides,
as a safe harbor, that a separate account will be treated as being adequately
diversified if the diversification requirements under Subchapter M are
satisfied and no more than 55% of the value of the account's total assets are
cash and cash items, government securities and securities of other RICs.
Failure of a Portfolio to satisfy the section 817(h) requirements would result
in taxation of the insurance company issuing the Contracts and treatment of the
Contract holders other than as described in the applicable Contract prospectus.
    
The foregoing is only a summary of some of the important federal income tax
considerations generally affecting the Portfolios and their shareholders; see
the Statement of Additional Information for a more detailed discussion.
Prospective shareholders are urged to consult their tax advisers.
 
                              VALUATION OF SHARES
   
The net asset value of each Portfolio's shares, other than the Money Market
Portfolio, fluctuates and is determined for all Portfolios as of the close of
regular trading on the NYSE (currently 4:00 p.m., eastern time) on each
Business Day. For each Portfolio other than the Money Market Portfolio, net
asset value per share is computed by dividing the value of the securities held
by the Portfolio plus any cash or other assets minus all liabilities by the
total number of Portfolio shares outstanding. Except for the Money Market
Portfolio, each Portfolio values its assets based on the current market value
where market quotations are readily available. If such value cannot be
established, the assets are valued at fair value as determined in good faith by
or under the direction of the Fund's board of trustees. The amortized cost
method of valuation generally is used to value debt obligations with 60 days or
less remaining to maturity, unless the board of trustees determines that this
does not represent fair value. All investments denominated in foreign currency
are valued daily in U.S. dollars on the basis of the then-prevailing exchange
rates.     
 
The Money Market Portfolio intends to use its best efforts to maintain its net
asset value at $1.00 per share. The value of each share of this Portfolio is
computed by dividing its net assets by the number of its outstanding shares.
"Net assets" equals the value of the investments and other assets minus its
liabilities. The Money Market Portfolio values its portfolio securities using
the amortized cost method of valuation, under which market value is
approximated by amortizing the difference between the acquisition cost and
value at maturity of the instrument on a straight-line basis over its remaining
life. All cash, receivables and current payables are generally carried at their
face value. Other assets are valued at fair value as determined in good faith
by or under the direction of the Fund's board of trustees. All investments
denominated in foreign currencies are valued daily in U.S. dollars based on the
then-prevailing exchange rate. It should be recognized that judgment plays a
greater role in valuing lower rated debt securities because there is less
reliable, objective data available.
 
                                   MANAGEMENT
   
The Fund's board of trustees, as part of its overall management responsibility,
oversees various organizations responsible for each Portfolio's day-to-day
management. Mitchell Hutchins, the investment adviser and administrator for
each Portfolio, makes and implements all investment decisions and supervises
all aspects of the operations of the Money Market, High Grade Fixed Income,
Global Income, Asset Allocation, Growth and Income and Growth Portfolios.
Mitchell Hutchins supervises the activities of PIMCO, Nicholas-Applegate and
GEIM, the sub-advisers for the Strategic Fixed Income, Aggressive Growth and
Global Growth Portfolios, respectively, and supervises all other aspects of
these Portfolios' operations. PIMCO, Nicholas-Applegate and GEIM, as sub-
advisers for the Strategic Fixed Income, Aggressive Growth and Global Growth
Portfolios,     
 
                                     PW 27

respectively, make and implement all investment decisions for these Portfolios.
Brokerage transactions for the Portfolios may be conducted through PaineWebber
or its affiliates in accordance with procedures adopted by the Fund's board of
trustees.
       
For advisory and administrative services, the Fund pays Mitchell Hutchins a
fee, computed daily and paid monthly, at the following annual rates for each
Portfolio:

The fee of .75% of average net assets paid by the Global Income, Growth and
Global Growth Portfolios and the fee of .80% of average net assets paid by the
Aggressive Growth Portfolio are higher than those paid by most funds to their
advisers but not higher than fees paid by many funds with similar objectives
and policies. THE FEE OF .75% OF AVERAGE NET ASSETS PAID BY THE ASSET
ALLOCATION PORTFOLIO IS HIGHER THAN THAT PAID BY FUNDS WITH SIMILAR INVESTMENT
OBJECTIVES AND POLICIES TO THEIR ADVISERS.     
   
The Portfolios also incur other expenses in their operations. For the fiscal
year ended December 31, 1994, total expenses stated as a percentage of average
net assets were .88% for the Money Market Portfolio, .89% for the Strategic
Fixed Income Portfolio, 1.17% for the Global Income Portfolio, 1.03% for the
Asset Allocation Portfolio, 1.35% for the Growth and Income Portfolio, 1.00%
for the Growth Portfolio, 1.48% for the Global Growth Portfolio, 1.56% for the
High Grade Fixed Income Portfolio, and 1.59% for the Aggressive Growth
Portfolio.

                              GENERAL INFORMATION
 
The Fund is registered with the SEC as an open-end management investment
company and was organized as a business trust under the laws of the
Commonwealth of Massachusetts by Declaration of Trust dated November 21, 1986.
The Fund commenced operations as an investment company on May 4, 1987. The
trustees have authority to issue an unlimited number of shares of beneficial
interest of separate series, par value $.001 per share. Shares of ten series
are authorized.
 
The Fund does not hold annual meetings of shareholders. There normally will be
no meetings of shareholders to elect trustees unless fewer than a majority of
the trustees holding office have been elected by shareholders. Shareholders of
record of no less than two-thirds of the outstanding shares of the Fund may
remove a trustee by votes cast in person or by proxy at a meeting called for
that purpose. The trustees are required to call a meeting of shareholders for
the purpose of voting upon the question of removal of any trustee when so
requested in writing by the shareholders of record of not less than 10% of the
Fund's outstanding shares. Each share of a Portfolio has equal voting, dividend
and liquidation rights. The shares of each Portfolio will be voted separately
except when an aggregate vote of all series is required by the 1940 Act.

                                                                      APPENDIX A
 
GINNIE MAE CERTIFICATES. Ginnie Mae guarantees certain mortgage pass-through
certificates ("Ginnie Mae certificates") that are issued by Private Mortgage
Lenders and that represent ownership interests in individual pools of
residential mortgage loans. These securities are designed to provide monthly
payments of interest and principal to the investor. Timely payment of interest
and principal (but not the market value of the security itself) is backed by
the full faith and credit of the U.S. government. Each mortgagor's monthly
payments to his lending institution on his residential mortgage are "passed
through" to certificateholders such as a Portfolio. Mortgage pools consist of
whole mortgage loans or participations in loans. The terms and characteristics
of the mortgage instruments are generally uniform within a pool but may vary
among pools. Lending institutions that originate mortgages for the pools are
subject to certain standards, including credit and other underwriting criteria
for individual mortgages included in the pools.
 
FANNIE MAE CERTIFICATES. Fannie Mae facilitates a national secondary market in
residential mortgage loans insured or guaranteed by U.S. government agencies
and in privately insured or uninsured residential mortgage loans (sometimes
referred to as "conventional mortgage loans" or "conventional loans") through
its mortgage purchase and mortgage-backed securities sales activities. Fannie
Mae issues guaranteed mortgage pass-through certificates ("Fannie Mae
certificates"), which represent pro rata shares of all interest and principal
payments made and owed on the underlying pools. Fannie Mae guarantees timely
payment of interest and principal (but not the market value of the security
itself) on Fannie Mae certificates. The Fannie Mae guarantee is not backed by
the full faith and credit of the U.S. government.
 
FREDDIE MAC CERTIFICATES. Freddie Mac also facilitates a national secondary
market for conventional residential and U.S. government-issued mortgage loans
through its mortgage purchase and mortgage-backed securities sales activities.
Freddie Mac issues two types of mortgage pass-through securities: mortgage
participation certificates ("PCs") and guaranteed mortgage certificates
("GMCs"). Each PC represents a pro rata share of all interest and principal
payments made and owed on the underlying pool. Freddie Mac generally guarantees
timely monthly payment of interest on PCs and the ultimate payment of
principal, but it also has a PC program under which it guarantees timely
payment of both principal and interest. GMCs also represent a pro rata interest
in a pool of mortgages. These instruments, however, pay interest semi-annually
and return principal once a year in guaranteed minimum payments. Freddie Mac
does not guarantee the market value of the security itself. The Freddie Mac
guarantee is not backed by full faith and credit of the U.S. government.
 
PRIVATE, RTC AND SIMILAR MORTGAGE-BACKED SECURITIES. Mortgage-backed securities
issued by Private Mortgage Lenders are structured similarly to the CMOs or
single class mortgage-backed securities issued or guaranteed by Ginnie Mae,
Fannie Mae and Freddie Mac. Such mortgage-backed securities may be supported by
pools of U.S. government or agency insured or guaranteed mortgage loans or by
other mortgage-backed securities issued by a government agency or
instrumentality, but they generally are supported by pools of conventional
(i.e., non-government guaranteed or insured) mortgage loans. Since such
mortgage-backed securities normally are not guaranteed by an entity having the
credit standing of Ginnie Mae, Fannie Mae or Freddie Mac, they normally are
structured with one or more types of credit enhancement. See "--Types of Credit
Enhancement." Such credit enhancements do not protect investors from changes in
market value.
 
The Resolution Trust Corporation ("RTC"), which was organized by the U.S.
government in connection with the savings and loan crisis, holds assets of
failed savings associations as either a conservator or receiver for such
associations, or it acquires such assets in its corporate capacity. These
assets include, among other things, single family and multi-family mortgage
loans, as well as commercial mortgage loans. In order to dispose of such assets
in an orderly manner, RTC has established a vehicle registered with the SEC
through which it sells mortgage-backed securities. RTC
 
                                     PW 32
<PAGE>
 
mortgage-backed securities represent pro rata interests in pools of mortgage
loans that RTC holds or has acquired, as described above, and are supported by
one or more of the types of private credit enhancements used by Private
Mortgage Lenders.
 
COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTI-CLASS MORTGAGE PASS-THROUGHS.
CMOs are debt obligations that are collateralized either by mortgage loans,
mortgage pass-through securities or other CMOs (such collateral collectively
being called "Mortgage Assets"). CMOs may be issued by Private Mortgage Lenders
or by government entities such as Fannie Mae or Freddie Mac. Multi-class
mortgage pass-through securities are interests in trusts that are comprised of
Mortgage Assets and that have multiple classes similar to those of CMOs. Unless
the context indicates otherwise, references herein to CMOs include multi-class
mortgage pass-through securities. Payments of principal of and interest on the
Mortgage Assets (and in the case of CMO's any reinvestment income thereon)
provide the funds to pay debt service on the CMOs or to make scheduled
distributions on the multi-class mortgage pass-through securities.
 
In a CMO, a series of bonds or certificates is issued in multiple classes. Each
class of CMO, also referred to as a "tranche," is issued at a specific fixed or
floating coupon rate and has a stated maturity or final distribution date.
Principal prepayments on the Mortgage Assets may cause CMOs to be retired
substantially earlier than their stated maturities or final distribution dates.
Interest is paid or accrues on all classes of a CMO (other than any principal-
only or PO class) on a monthly, quarterly or semi-annual basis. The principal
and interest on the Mortgage Assets may be allocated among the several classes
of a CMO in many ways. In one structure, payments of principal, including any
principal prepayments, on the Mortgage Assets are applied to the classes of a
CMO in the order of their respective stated maturities or final distribution
dates so that no payment of principal will be made on any class of the CMO
until all other classes having an earlier stated maturity or final distribution
date have been paid in full. In some CMO structures, all or a portion of the
interest attributable to one or more of the CMO classes may be added to the
principal amounts attributable to such classes, rather than passed through to
certificateholders on a current basis, until other classes of the CMO are paid
in full.
 
Parallel pay CMOs are structured to provide payments of principal on each
payment date to more than one class. These simultaneous payments are taken into
account in calculating the stated maturity date or final distribution date of
each class, which, as with other CMO structures, must be retired by its stated
maturity date or final distribution date but may be retired earlier.
 
ARM AND FLOATING RATE MORTGAGE-BACKED SECURITIES. ARM mortgage-backed
securities are mortgage-backed securities that represent a right to receive
interest payments at a rate that is adjusted to reflect the interest earned on
a pool of mortgage loans bearing variable or adjustable rates of interest (such
mortgage loans are referred to as "ARMs"). Floating rate mortgage-backed
securities are classes of mortgage-backed securities that have been structured
to represent the right to receive interest payments at rates that fluctuate in
accordance with an index but that generally are supported by pools comprised of
fixed-rate mortgage loans. Because the interest rates on ARM and floating rate
mortgage-backed securities are reset in response to changes in a specified
market index, the values of such securities tend to be less sensitive to
interest rate fluctuations than the values of fixed-rate securities.
 
TYPES OF CREDIT ENHANCEMENT. To lessen the effect of failures by obligors on
Mortgage Assets to make payments, mortgage-backed securities may contain
elements of credit enhancement. Such credit enhancement falls into two
categories: (1) liquidity protection; and (2) protection against losses
resulting after default by an obligor on the underlying assets and collection
of all amounts recoverable directly from the obligor and through liquidation of
the collateral. Liquidity protection refers to the provision of advances,
generally by the entity administering the pool of assets (usually the bank,
savings association or mortgage banker that transferred the underlying loans to
the issuer
 
                                     PW 33
<PAGE>
 
of the security), to ensure that the receipt of payments on the underlying pool
occurs in a timely fashion. Protection against losses resulting after default
and liquidation ensures ultimate payment of the obligations on at least a
portion of the assets in the pool. Such protection may be provided through
guarantees, insurance policies or letters of credit obtained by the issuer or
sponsor from third parties, through various means of structuring the
transaction or through a combination of such approaches. The Portfolios will
not pay any additional fees for such credit enhancement, although the existence
of credit enhancement may increase the price of a security.
 
Examples of credit enhancement arising out of the structure of the transaction
include "senior-subordinated securities" (multiple class securities with one or
more classes subordinate to other classes as to the payment of principal
thereof and interest thereon, with the result that defaults on the underlying
assets are borne first by the holders of the subordinated class), creation of
"spread accounts" or "reserve funds" (where cash or investments, sometimes
funded from a portion of the payments on the underlying assets, are held in
reserve against future losses) and "over-collateralization" (where the
scheduled payments on, or the principal amount of, the underlying assets exceed
that required to make payment of the securities and pay any servicing or other
fees). The degree of credit enhancement provided for each issue generally is
based on historical information regarding the level of credit risk associated
with the underlying assets. Delinquency or loss in excess of that anticipated
could adversely affect the return on an investment in such a security.
 
SPECIALLY STRUCTURED CMOS AND NEW TYPES OF MORTGAGE-BACKED SECURITIES
 
The Portfolios may invest in IOs, POs, inverse floating rate CMOs and other
specially structured CMO classes. See "Risk Factors and Other Investment
Policies--Risks of Mortgage- and Asset-Backed Securities."
 
New types of mortgage-backed securities are developed and marketed from time to
time and, consistent with their investment limitations, the Portfolios expect
to invest in those new types of mortgage-backed securities that Mitchell
Hutchins or the applicable sub-adviser believes may assist a Portfolio in
achieving its investment objective. Similarly, the Portfolios may invest in
mortgage-backed securities issued by new or existing governmental or private
issuers other than those identified above. The Fund's prospectus or statement
of additional information will be supplemented to the extent that new types of
mortgage-backed securities or those issued by issuers other than those
identified above involve materially different risks than the securities or
issuers described herein.

                     HEDGING AND OPTION INCOME INSTRUMENTS
 
Certain Portfolios may use the following hedging instruments:
 
  OPTIONS ON EQUITY AND DEBT SECURITIES AND FOREIGN CURRENCIES--A call option
  is a short-term contract pursuant to which the purchaser of the option, in
  return for a premium, has the right to buy the security or currency
  underlying the option at a specified price at any time during the term of
  the option. The writer of the call option, who receives the premium, has
  the obligation, upon exercise of the option during the option term, to
  deliver the underlying security or currency against payment of the exercise
  price. A put option is a similar contract that gives its purchaser, in
  return for a premium, the right to sell the underlying security or currency
  at a specified price during the option term. The writer of the put option,
  who receives the premium, has the obligation, upon exercise of the option
  during the option term, to buy the underlying security or currency at the
  exercise price.
 
  OPTIONS ON STOCK INDEXES--A stock index assigns relative values to the
  stocks included in the index and fluctuates with changes in the market
  values of those stocks. A stock index option operates in the same way as a
  more traditional stock option, except that exercise of a stock index option
  is effected with cash payment and does not involve delivery of securities.
  Thus, upon exercise of a stock index option, the purchaser will realize,
  and the writer will pay, an amount based on the difference between the
  exercise price and the closing price of the stock index.
 
  STOCK INDEX FUTURES CONTRACTS--A stock index futures contract is a
  bilateral agreement pursuant to which one party agrees to accept, and the
  other party agrees to make, delivery of an amount of cash equal to a
  specified dollar amount times the difference between the stock index value
  at the close of trading of the contract and the price at which the futures
  contract is originally struck. No physical delivery of the stocks
  comprising the index is made. Generally, contracts are closed out prior to
  the expiration date of the contract.
 
  INTEREST RATE AND FOREIGN CURRENCY FUTURES CONTRACTS--Interest rate and
  foreign currency futures contracts are bilateral agreements pursuant to
  which one party agrees to make, and the other party agrees to accept,
  delivery of a specified type of debt security or currency at a specified
  future time and at a specified price. Although such futures contracts by
  their terms call for actual delivery or acceptance of debt securities or
  currency, in most cases the contracts are closed out before the settlement
  date without the making or taking of delivery.
 
  OPTIONS ON FUTURES CONTRACTS--Options on futures contracts are similar to
  options on securities or currency, except that an option on a futures
  contract gives the purchaser the right, in return for the premium, 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), rather than to purchase
  or sell a security or currency, at a specified price at any time during the
  option term. Upon exercise of the option, the delivery of the futures
  position to the holder of the option will be accompanied by delivery of the
  accumulated balance that represents the amount by which the market price of
  the futures contract 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 future. The
  writer of an option, upon exercise, will assume a short position in the
  case of a call and a long position in the case of a put.
 
  FORWARD CURRENCY CONTRACTS--A forward currency contract involves an
  obligation to purchase or sell a specific currency at a specified future
  date, which may be any fixed number of days from the contract date agreed
  upon by the parties, at a price set at the time the contract is entered
  into.

                THE FUND, ITS INVESTMENT OBJECTIVES AND POLICIES
 
The Fund is a professionally managed mutual fund. The Fund offers seven
Portfolios, each of which represents a segregated, separately managed portfolio
of securities with its own investment objective, as set forth on page PW 1, and
its own investment policies, which are summarized on page PW 1 and set forth in
more detail below. There can be no assurance that any Portfolio's investment
objective will be met. The Global Income Portfolio is managed as a non-
diversified investment company; the other Portfolios are all managed as
diversified investment companies.
 
Shares of each Portfolio are offered only to insurance company separate
accounts that fund the Contracts. An insurance company separate account's
interest is limited to the Portfolio(s) in which the separate account invests.
Separate accounts may purchase or redeem shares at net asset value without any
sales or redemption charge. Fees and charges imposed by the separate account,
however, will affect the actual return to the holder of a Contract. A separate
account may also impose certain restrictions or limitations on the allocation
of purchase payments or Contract value to one or more Portfolios, and not all
Portfolios may be available in connection with a particular Contract.
Prospective investors should consult the applicable Contract prospectus for
information regarding fees and expenses of the Contract and separate account
and any applicable restrictions or limitations.
 
Shares of the Portfolios may be offered to separate accounts of various
insurance companies ("shared funding") and may serve as the underlying
investments for both annuity and life insurance Contracts ("mixed funding").
Due to differences in tax treatment or other considerations, the interests of
various Contract owners might at some time be in conflict. The Fund currently
does not foresee any such conflict. However, the Fund's board of trustees
intends to monitor events to identify any material irreconcilable conflict that
may arise and to determine what action, if any, should be taken in response to
such conflict. If such a conflict were to occur, one or more insurance
companies' separate accounts might be required to withdraw its investments in
one or more Portfolios. This might force a Portfolio to sell securities at
disadvantageous prices.
 
The MONEY MARKET PORTFOLIO invests in high grade money market instruments, with
remaining maturities of 13 months or less, and repurchase agreements secured by
such instruments and maintains a dollar-weighted average portfolio maturity of
90 days or less. These instruments include (1) U.S. government securities
(which may or may not be backed by the full faith and credit of the United
States), (2) obligations (including certificates of deposit, bankers'
acceptances and similar obligations) of U.S. banks, including foreign branches
of domestic banks and domestic branches of foreign banks, having total assets
in excess of $1.5 billion at the time of purchase, (3) interest-bearing savings
deposits in U.S. commercial and savings banks having total assets of $1.5
billion or less, provided that the principal amounts at each such bank are
fully insured by the Federal Deposit Insurance Corporation and the aggregate
amount of such deposits (plus interest earned) does not exceed 5% of the
Portfolio's asset value and (4) commercial paper and other short-term corporate
obligations including variable and floating rate securities and participation
interests. Participation interests are pro rata interests in securities held by
others.
 
The commercial paper and other short-term corporate obligations purchased by
the Money Market Portfolio consist only of obligations that Mitchell Hutchins
determines, pursuant to procedures adopted by the Fund's board of trustees,
present minimal credit risks and are either (1) rated in the highest short-term
rating category by at least two nationally recognized statistical rating
organizations ("NRSROs"), (2) rated in the highest short-term rating category
by a single NRSRO if only that NRSRO has assigned the obligations a short-term
rating or (3) unrated, but determined by Mitchell Hutchins to be of comparable
quality ("First Tier Securities"). The Money Market Portfolio generally may
invest no more than 5% of its total assets in the securities of a single issuer
(other than securities issued by the U.S. government, its agencies or
instrumentalities).
 
 
                                      PW 9
<PAGE>
 
   
The GROWTH PORTFOLIO invests primarily in equity securities (common stocks and
securities convertible into common stock) issued by companies that, in the
judgment of Mitchell Hutchins, have substantial potential for capital growth.
In selecting equity securities for investment by the Portfolio, Mitchell
Hutchins considers all of those factors it believes affect potential for
capital appreciation, including an issuer's current and projected revenues,
earnings, cash flow and assets, as well as general market conditions in
relevant industries. Under normal circumstances, at least 65% of the
Portfolio's total assets is invested in equity securities. For potential
capital appreciation (when, for instance, Mitchell Hutchins anticipates that
market interest rates may decline or credit factors or ratings affecting
particular issues may improve), the Portfolio's investment policies also permit
investment of up to 35% of the Portfolio's total assets in investment grade
debt securities. The Portfolio's investments in equity securities may include
investments of up to 35% of its total assets in convertible debt securities
that are related below investment grade but no lower than B by Standard &
Poor's ("S&P") or Moody's ("Moody's"), comparably rated by another NRSRO or, if
unrated, determined by Mitchell Hutchins to be of comparable quality. (For an
explanation of the ratings assigned to debt securities by S&P and Moody's, see
the Statement of Additional Information.) Consistent with its investment
objective, the Portfolio may also invest up to 25% of its total assets in U.S.
dollar-denominated securities of foreign issuers if the securities are traded
on recognized U.S. exchanges or in the U.S. over-the-counter ("OTC") market.
       
The GROWTH AND INCOME PORTFOLIO, under normal circumstances, invests at least
65% of its total assets in dividend-paying equity securities (common and
preferred stocks) believed by Mitchell Hutchins to have the potential for rapid
earnings growth. In managing the Portfolio, Mitchell Hutchins follows a
disciplined methodology under which stocks from a universe of approximately
2,000 medium to large capitalization companies are ranked utilizing
quantitative measures of value, earnings and price momentum in the context of
Mitchell Hutchins' economic forecast. Stocks are selected for the Portfolio
based on fundamental analysis of the highest ranking stocks. The Portfolio may
invest up to 35% of its total assets in equity securities not meeting the above
criteria, as well as convertible securities, U.S. government securities,
investment grade corporate debt securities and money market securities. The
Portfolio is permitted to invest up to 10% of its total assets in convertible
securities rated below investment grade but no lower than B by S&P or Moody's,
comparably rated by another NRSRO or, if unrated, determined by Mitchell
Hutchins to be of comparable quality. The Portfolio will invest in instruments
other than equity securities when, in the opinion of Mitchell Hutchins, their
projected total return is equal to or greater than that of equity securities or
when such holdings might reduce the volatility of its portfolio. The Portfolio
may invest up to 25% of its total assets in U.S. dollar-denominated securities
of foreign issuers that are traded on recognized U.S. exchanges or in the U.S.
OTC market.     
   
Over the past 65 years, the total return of equity investments, as measured by
the Standard & Poor's 500 Composite Stock Price Index ("S&P 500"), has exceeded
the inflation rate, as measured by the Consumer Price Index, as well as total
return on long-term Treasury bonds, long-term corporate bonds and short-term
Treasury bills. However, year-to-year fluctuations in each of these indices and
instruments have been significant, and total return for the S&P 500 for some
periods has been negative. There can be no assurance that this trend will
continue, and the Portfolio performance may be better or worse than that of the
S&P 500.     
          
The GLOBAL GROWTH PORTFOLIO invests primarily in the common stocks of companies
based in the United States, Europe, Japan and the Pacific Basin. Under normal
conditions, at least 65% of the Portfolio's total assets is invested in common
stocks and securities convertible into common stocks. The Portfolio will at all
times hold securities of issuers located in at least five countries and will
invest no more than 20% of its total assets in issuers located in any single
country outside the United States, except that the Portfolio may invest up to
35% of its total assets in issuers located in Japan. The Portfolio's sub-
adviser, GE Investment Management Incorporated ("GEIM"), seeks to identify     
 
                                     PW 10
<PAGE>
 
   
companies that have potential for growth and whose value has not been fully
recognized by the marketplace. GEIM concentrates primarily on medium to large-
size companies that it believes meet this undervalued growth criterion. The
Portfolio may also hold other types of securities, including non-convertible
investment grade corporate debt securities, government and money market
securities of U.S. and foreign issuers, and cash (foreign currencies or U.S.
dollars), in such proportions as, in the opinion of GEIM, prevailing market,
economic or political conditions warrant.     
   
The GLOBAL INCOME PORTFOLIO invests principally in high quality debt securities
of foreign and U.S. issuers. Debt securities will be considered high quality if
they are assigned one of S&P's or Moody's two highest ratings, comparably rated
by another NRSRO or, if unrated, determined by Mitchell Hutchins to be of
comparable quality. Normally, at least 65% of the Portfolio's total assets are
invested in high quality debt securities, denominated in foreign currencies or
U.S. dollars, that are issued or guaranteed by foreign and U.S. governments or
their agencies, instrumentalities or political subdivisions or by supranational
organizations such as the International Bank for Reconstruction and Development
("World Bank"), or that are issued by foreign and U.S. companies, banks and
bank holding companies. Such issuers will be located in at least five of the
following countries: Australia, Austria, Belgium, Canada, Denmark, Finland,
France, Germany, Hong Kong, Ireland, Italy, Japan, the Netherlands, New
Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, Thailand, the
United Kingdom and the United States. No more than 20% of the Portfolio's total
assets will be invested in securities of issuers located in any one country,
except that the Portfolio may invest up to 35% of its total assets in
securities of issuers located in any one of the following countries: Australia,
Canada, France, Germany, Japan and the United Kingdom. There is no limit on the
amount of assets that may be invested in securities of U.S. issuers. Mitchell
Hutchins expects that normally more than 50% of the Portfolio's total assets
will be invested in U.S. and foreign government securities in order to minimize
credit risk and to capitalize on opportunities that historically have been
presented by, and are perceived to exist today with respect to, such
instruments. Up to 35% of the Portfolio's total assets may be invested in
investment grade debt securities rated below the two highest grades assigned by
a NRSRO within this 35% limitation, or, if unrated, determined by Mitchell
Hutchins to be of comparable quality. The Portfolio may invest up to 20% of its
total assets in sovereign debt securities rated below but no lower than BB by
S&P, Ba by Moody's comparably rated by another NRSRO or, in the case of such
securities assigned a commercial paper rating, no lower than B by S&P or
comparably rated by another NRSRO or, if unrated, determined by Mitchell
Hutchins to be of comparable quality. Mitchell Hutchins will purchase such
securities for the Portfolio only when it concludes that the anticipated return
to the Portfolio on such investment warrants exposure to the additional level
of risk. Fundamental economic strength, credit quality and currency and
interest rate trends are the principal determinants of the various country,
geographic and industry sector weightings within the Portfolio. Up to 5% of the
Portfolio's total assets may be invested in debt securities convertible into
equity, although the Portfolio has no current intention of converting such
securities into equity or holding them as equity upon conversion.     
 
The Global Income Portfolio is "non-diversified," as that term is defined in
the Investment Company Act of 1940 ("1940 Act"), but intends to continue to
qualify as a "regulated investment company" for federal income tax purposes.
This means, in general, that although more than 5% of the Portfolio's total
assets may be invested in the securities of one issuer (including a foreign
government), at the close of each quarter of the Portfolio's taxable year the
aggregate amount of such holdings may not exceed 50% of the value of its total
assets, and no more than 25% of the value of its total assets may be invested
in the securities of a single issuer. To the extent that the Portfolio at times
may hold the securities of a smaller number of issuers than if it were
"diversified" (as defined in the 1940 Act), the Portfolio will at such times be
subject to greater risk with respect to its portfolio securities than a fund
that invests in a broader range of securities, because changes in the financial
condition or market assessment of a single issuer may cause greater
fluctuations in the Portfolio's total return and the net asset value of its
shares.

The STRATEGIC FIXED INCOME PORTFOLIO invests in a portfolio of fixed income
securities of varying maturities with a dollar-weighted average portfolio
duration between three and eight years. Portfolio holdings will be invested in
areas of the bond market (based on quality, sector, coupon or maturity) that
its sub-adviser, Pacific Investment Management Company ("PIMCO"), believes to
be relatively undervalued. Under normal circumstances, the Portfolio invests at
least 65% of its assets in fixed income securities, which include obligations
issued or guaranteed by the U.S. government, its agencies and
instrumentalities, corporate and other debt obligations, convertible
securities, mortgage- and asset-backed securities, obligations of foreign
governments or their subdivisions, agencies or instrumentalities, obligations
of supranational and quasi-governmental entities, commercial paper,
certificates of deposit, money market instruments, foreign currency exchange-
related securities and loan participations and assignments. The Portfolio may
invest up to 35% of its total assets in privately issued mortgage-related
securities. All of the securities purchased for the Portfolio will be
investment grade, except that the Portfolio may invest up to 20% of its total
assets in securities rated below investment grade, but rated at least B by S&P
or Moody's, assigned a comparable rating by another nationally recognized
statistical ratings service ("NRSRO") or, if unrated, determined by the sub-
adviser to be of comparable quality. Securities rated below investment grade
are commonly known as "junk bonds." The Portfolio may invest up to 10% of its
assets in securities denominated in foreign currencies and dollar-denominated
debt of foreign issuers. In addition, the Portfolio may invest up to 10% of its
assets in Yankee bonds and Eurodollar bonds combined. Yankee bonds are U.S.
dollar-denominated obligations of foreign issuers and Eurodollar bonds are U.S.
dollar-denominated obligations of domestic issuers that are held outside the
United States, primarily in Europe.     
          
The ASSET ALLOCATION PORTFOLIO operates as a balanced fund and invests
primarily in a combination of equity securities, investment grade debt
obligations and money market instruments, based on Mitchell Hutchins'
assessment of the optimal allocation of the Portfolio's assets. The Portfolio
seeks to maintain a dollar-weighted average maturity for its fixed income
investments of three to ten years. Under normal conditions, at least 25% of the
Portfolio's assets will be invested in debt obligations, including money market
instruments. Mitchell Hutchins believes that capital market returns reflect the
consensus expectations for key economic variables, such as interest rates,
profit growth and inflation, and that superior performance can be obtained by
reallocating assets from time to time before changes in the consensus outlook
have been fully discounted by the market. To implement this strategy, Mitchell
Hutchins regularly surveys market participants and generates a consensus
forecast of economic variables affecting returns on equity, fixed income and
money market investments. Mitchell Hutchins then applies fundamental valuation
techniques to the consensus date to determine what it believes is the optimal
asset allocation for the Portfolio. Portfolio managers specializing in each
asset class then select specific securities for their allocated portions of the
portfolio. Mitchell Hutchins regularly monitors market outlooks and changes
asset allocations when there are significant changes in expected returns.     
   
Equity Securities. In selecting equity securities for the Portfolio, Mitchell
Hutchins follows a disciplined methodology under which stocks from a universe
of approximately 2,000 medium to large capitalization (generally at least $300
million) companies are ranked utilizing quantitative measures of value,
earnings and price momentum in the context of Mitchell Hutchins' economic
forecast. Stocks are selected for the Portfolio based on fundamental analysis
of the highest ranking stocks.     
   
Debt Securities. The Portfolio's investments in debt securities are based on
analyses of the maturity structure and the risk structure (comparing yields on
U.S. Treasury securities to yields on riskier types of debt securities). The
Portfolio may invest in a broad range of investment grade bonds, securities
issued or guaranteed by the U.S. government, its agencies or instrumentalities,
including mortgage-backed securities, and other fixed income securities. The
maturity of a mortgage-backed security is deemed to be its effective life
(i.e., the average time in which it is expected that the     
 
                                     PW 12
<PAGE>
 
   
principal amount of the security will be repaid), as estimated by Mitchell
Hutchins based upon scheduled principal amortization and an anticipated rate of
principal prepayments, which, in turn, is based upon past prepayment patterns,
prevailing interest rates and other factors. The effective life of a mortgage-
backed security generally is substantially shorter than its stated maturity.
    
          
Money Market Instruments. The Portfolio may invest in high grade money market
instruments, which are debt securities with maturities of 13 months or less.
Such instruments will be chosen by Mitchell Hutchins based on its judgment of
their utility in furthering the Portfolio's investment objective. For a more
detailed description of the money market instruments in which the Portfolio's
invests, see the Statement of Additional Information.     
   
The Portfolio may invest in U.S. dollar-denominated securities of foreign
issuers that are traded on recognized U.S. exchanges or in the U.S. OTC market.
    
              DESCRIPTION OF SECURITIES AND INVESTMENT TECHNIQUES
   
U.S. GOVERNMENT SECURITIES. Under normal market conditions, the Strategic Fixed
Income Portfolio, Global Income Portfolio and Asset Allocation Portfolio are
authorized to invest a substantial portion of their assets in U.S. government
securities and the other Portfolios may invest in U.S. government securities
consistent with their investment objectives. The U.S. government securities in
which the Portfolios may invest include direct obligations of the U.S.
government (such as Treasury bills, notes and bonds) and obligations issued by
U.S. government agencies and instrumentalities, including securities that are
backed by the full faith and credit of the U.S. government (such as Government
National Mortgage Association ("Ginnie Mae") certificates) and securities that
are supported primarily or solely by the creditworthiness of the issuer (such
as securities of the Federal National Mortgage Association ("Fannie Mae"), the
Federal Home Loan Mortgage Corporation ("Freddie Mac") and the Tennessee Valley
Authority). U.S. government securities are considered among the most
creditworthy of fixed income investments. Because of this, the yields available
from U.S. government securities are generally lower than the yields available
from corporate debt securities. Nevertheless, the values of U.S. government
securities (like those of fixed income securities generally) will change as
interest rates fluctuate.     
   
MORTGAGE- AND ASSET-BACKED SECURITIES. Mortgage-backed securities represent
direct or indirect participations in, or are secured by and payable from,
mortgage loans secured by real property and include single- and multi-class
pass-through securities and collateralized mortgage obligations. Multi-class
pass-through securities and collateralized mortgage obligations are
collectively referred to herein as CMOs. U.S. government mortgage-backed
securities include mortgage-backed securities issued or guaranteed as to the
payment of principal and interest (but not as to market value) by Ginnie Mae,
Fannie Mae or Freddie Mac. Other mortgage-backed securities are issued by
private issuers, generally originators of and investors in mortgage loans,
including savings associations, mortgage bankers, commercial banks, investment
bankers and special purpose entities (collectively, "Private Mortgage
Lenders"). Payments of principal and interest (but not the market value) of
such private mortgage-backed securities may be supported by pools of mortgage
loans or other mortgage-backed securities that are guaranteed, directly or
indirectly, by the U.S. government or one of its agencies or instrumentalities,
or they may be issued without any government guarantee of the underlying
mortgage assets but with some form of non-governmental credit enhancement.     
 
Asset-backed securities have structural characteristics similar to mortgage-
backed securities. However, the underlying assets are not first-lien mortgage
loans or interests therein, but include assets such as motor vehicle
installment sales contracts, other installment loan contracts, home equity
loans, leases of various types of real and personal property and receivables
from revolving credit (credit card) agreements. Such assets are securitized
through the use of trusts or special
 
                                     PW 13
<PAGE>
 
   
purpose corporations. Payments or distributions of principal and interest on
asset-backed securities may be guaranteed up to certain amounts and for a
certain time period by a letter of credit or a pool insurance policy issued by
a financial institution unaffiliated with the issuer or other credit
enhancements may be present. Asset-backed securities are discussed further in
the Statement of Additional Information.     
   
The yield characteristics of mortgage- and asset-backed securities differ from
those of traditional debt securities. Among the major differences are that
interest and principal payments are made more frequently on mortgage- and
asset-backed securities, usually monthly, and that principal may be prepaid at
any time because the underlying mortgage loans or other assets generally may be
prepaid at any time. As a result, if a Portfolio purchases these securities at
a premium, a prepayment rate that is faster than expected will reduce yield to
maturity, while a prepayment rate that is slower than expected will have the
opposite effect of increasing yield to maturity. Conversely, if a Portfolio
purchases these securities at a discount, faster than expected prepayments will
increase, while slower than expected prepayments will reduce, yield to
maturity. Amounts available for reinvestment are likely to be greater during a
period of declining interest rates and, as a result, are likely to be
reinvested at lower interest rates than during a period of rising interest
rates. Accelerated prepayments on securities purchased by a Portfolio at a
premium also impose a risk of loss of principal because the premium may not
have been fully amortized at the time the principal is repaid in full. The
market for privately issued mortgage- and asset-backed securities is smaller
and less liquid than the market for mortgage-backed securities of government
issuers.     
 
CMO classes may be specially structured in a manner that provides any of a wide
variety of investment characteristics, such as yield, effective maturity and
interest rate sensitivity. As market conditions change, however, and
particularly during periods of rapid or unanticipated changes in market
interest rates, the attractiveness of the CMO classes and the ability of the
structure to provide the anticipated investment characteristics may be
significantly reduced. These changes can result in volatility in the market
value, and in some instances reduced liquidity, of the CMO class.
 
The rate of interest payable on CMO classes may be set at levels that are
either above or below market rates at the time of issuance, so that the
securities will be sold at a substantial premium to, or at a discount from, par
value. In the most extreme case, one class will be entitled to receive all or a
portion of the interest but none of the principal from the underlying mortgage
assets (the interest-only or "IO" class) and one class will be entitled to
receive all or a portion of the principal but none of the interest (the
principal-only or "PO" class). IOs and POs may also be created from mortgage-
backed securities that are not CMOs. The yields on IOs, POs and other mortgage-
backed securities that are purchased at a substantial premium or discount
generally are extremely sensitive to the rate of principal payments (including
prepayments) on the underlying mortgage assets. If the mortgage assets
underlying an IO experience greater than anticipated principal prepayments, an
investor may fail to recoup fully his or her initial investment even if the
security is government issued or guaranteed or is rated AAA or the equivalent.
 
Some CMO classes are structured to pay interest at rates that are adjusted in
accordance with a formula, such as a multiple or fraction of the change in a
specified interest rate index, so as to pay at a rate that will be attractive
in certain interest rate environments but not in others. For example, an
inverse floating rate CMO class pays interest at a rate that increases as a
specified interest rate index decreases but decreases as that index increases.
For other CMO classes, the yield may move in the same direction as market
interest rates--i.e. the yield may increase as rates increase and decrease as
rates decrease--but may do so more rapidly or to a greater degree. The market
value of such securities generally is more volatile than that of a fixed rate
obligation. Such interest rate formulas may be combined with other CMO
characteristics. For example, a CMO class may be an "inverse IO," on which the
holders are entitled to receive no payments of principal and are entitled to
receive interest at a rate that will vary inversely with a specified index or a
multiple thereof.

<PAGE>
 
   
During 1994, the value and liquidity of many mortgage-backed securities
declined sharply due primarily to increases in interest rates. There can be no
assurance that such declines will not recur. The market value of certain
mortgage-backed securities, including IO and PO classes of mortgage-backed
securities and inverse floating rate securities, can be extremely volatile and
these securities may become illiquid. Mitchell Hutchins or the applicable sub-
adviser seeks to manage each Portfolio so that its volatility, taken as a
whole, is consistent with the Portfolio's investment objective. If Mitchell
Hutchins or the sub-adviser incorrectly forecasts interest rate changes or
other factors that may affect the volatility of securities held by the
Portfolio, the Portfolio's ability to meet its investment objective may be
reduced.     
 
See Appendix A to this Prospectus for more information concerning the types of
mortgage-backed securities in which the Portfolios may invest.
          
FOREIGN SECURITIES. The Global Growth and Global Income Portfolios invest a
substantial portion of their assets in foreign securities, and the Strategic
Fixed Income Portfolio may invest up to 10% of its assets in securities
denominated in foreign currencies and another 10% of its assets in Yankee and
Eurodollar bonds combined. In addition, the Growth and Growth and Income
Portfolios may each invest up to 25% of its total assets in U.S. dollar-
denominated securities of foreign issuers if such securities are traded on
recognized U.S. exchanges or in the U.S. OTC market and the Asset Allocation
Portfolio also may invest in such securities. Accordingly, an investment in any
of these Portfolios involves risks relating to political, social and economic
developments abroad, as well as risks resulting from the differences between
the regulations to which U.S. and foreign issuers and markets are subject.
These risks are greater with respect to the Global Growth and Global Income
Portfolios because a substantially greater portion of their assets may be
invested in such securities and because these Portfolios may invest
substantially in foreign securities that are denominated in foreign currencies
and traded outside the U.S. securities markets. These risks may include
expropriation, confiscatory taxation, withholding taxes on dividends and
interest, limitations on the use or transfer of Portfolio assets and political
or social instability or diplomatic developments. Moreover, individual foreign
economies may differ favorably or unfavorably from the U.S. economy in such
respects as growth of gross national product, rate of inflation, capital
reinvestment, resource self-sufficiency and balance of payments position.
Securities of many foreign companies may be less liquid and their prices more
volatile than securities of comparable U.S. companies. While the Portfolios
generally invest only in securities that are traded on recognized exchanges or
in OTC markets, from time to time foreign securities may be difficult to
liquidate rapidly without significantly depressing the price of such
securities. There may be less publicly available information concerning foreign
issues of securities held by these Portfolios than is available concerning U.S.
companies. Transactions in foreign securities may be subject to less efficient
settlement practices. Foreign securities trading practices, including those
involving securities settlement where Portfolio assets may be released prior to
receipt of payment, may expose a Portfolio to increased risk in the event of a
failed trade or the insolvency of a foreign broker-dealer. Legal remedies for
defaults and disputes may have to be pursued in foreign courts, whose
procedures differ substantially from those of U.S. courts.     
 
Because foreign securities ordinarily are denominated in currencies other than
the U.S. dollar (as are some securities of U.S. issuers), changes in foreign
currency exchange rates will affect a Portfolio's net asset value, the value of
dividends and interest earned, gains and losses realized on the sale of
securities and net investment income and capital gain, if any, to be
distributed to shareholders by the Portfolio. If the value of a foreign
currency rises against the U.S. dollar, the value of a Portfolio's assets
denominated in that currency will increase; correspondingly, if the value of a
foreign currency declines against the U.S. dollar, the value of a Portfolio's
assets denominated in that currency will decrease. The exchange rates between
the U.S. dollar and other currencies are determined by supply and demand in the
currency exchange markets, international balances of payments, speculation and
other economic and political conditions. In addition, some foreign currency
 
                                     PW 15
<PAGE>
 
values may be volatile and there is the possibility of governmental controls on
currency exchange or governmental intervention in currency markets. Any of
these factors could adversely affect these Portfolios.
   
The costs attributable to foreign investing that the Global Growth, Global
Income and Strategic Fixed Income Portfolios must bear frequently are higher
than those attributable to domestic investing. For example, the costs of
maintaining custody of securities in foreign countries exceed custodian costs
for domestic securities.     
   
The Strategic Fixed Income, Global Income and the Global Growth Portfolios may
invest in securities of issuers located in emerging market countries. The risks
of investing in foreign securities may be greater with respect to securities of
issuers in, or denominated in the currencies of, emerging market countries. The
economies of emerging market countries generally are heavily dependent upon
international trade and, accordingly, have been and may continue to be
adversely affected by trade barriers, exchange controls, managed adjustments in
relative currency values and other protectionist measures imposed or negotiated
by the countries with which they trade. These economies also have been and may
continue to be adversely affected by economic conditions in the countries with
which they trade. Many emerging market countries have experienced substantial,
and in some periods extremely high, rates of inflation for many years.
Inflation and rapid fluctuations in inflation rates have had and may continue
to have very negative effects on the economies and securities markets of
certain emerging market countries. The securities markets of emerging market
countries are substantially smaller, less developed, less liquid and more
volatile than the securities markets of the U.S. and other developed countries.
Disclosure and regulatory standards in many respects are less stringent in
emerging market countries than in the U.S. and other major markets. There also
may be a lower level of monitoring and regulation of emerging markets and the
activities of investors in such markets, and enforcement of existing
regulations may be extremely limited. Investing in local markets, particularly
in emerging market countries, may require these Portfolios to adopt special
procedures, seek local government approvals or take other actions, each of
which may involve additional costs to the Portfolios. Certain emerging market
countries may also restrict investment opportunities in issuers in industries
deemed important to national interests.     
 
FOREIGN GOVERNMENT SECURITIES. Foreign government securities generally consist
of obligations supported by national, state or provincial governments or
similar political subdivisions. Foreign government securities also include debt
obligations of supranational entities, which include international
organizations designated or supported by governmental entities to promote
economic reconstruction or development, international banking institutions and
related government agencies. Examples include the World Bank, the European Coal
and Steel Community, the Asian Development Bank and the InterAmerican
Development Bank.
 
Foreign government securities also include debt securities of "quasi-
governmental agencies" and debt securities denominated in multinational
currency units of an issuer (including supranational issuers). An example of a
multinational currency unit is the European Currency Unit ("ECU"). An ECU
represents specified amounts of the currencies of certain member states of the
European Union. Debt securities of quasi-governmental agencies are issued by
entities owned by either a national, state or equivalent government or are
obligations of a political unit that is not backed by the national government's
full faith and credit and general taxing powers. Foreign government securities
also include mortgage-related securities issued or guaranteed by national,
state or provincial governmental instrumentalities, including quasi-
governmental agencies.
 
FOREIGN BANK AND FOREIGN BRANCH INSTRUMENTS. The Money Market Portfolio may
invest in obligations of domestic branches of foreign banks and foreign
branches of domestic banks. The Global Income Portfolio may invest in these
instruments and also in obligations of bank holding companies and foreign
banks. The other Portfolios may invest in such securities consistent with their
 
                                     PW 16
<PAGE>
 
investment objectives and policies. Such investments may involve risks that are
different from investments in obligations of U.S. branches of domestic banks.
These risks may include future unfavorable political and economic developments,
possible withholding taxes, seizure of foreign deposits, currency controls,
interest limitations or other governmental restrictions that might affect the
payment of principal or interest on the securities held by a Portfolio.
Additionally, there may be less publicly available information about foreign
banks and foreign branches of U.S. banks, as these institutions may not be
subject to the same regulatory requirements as domestic banks.
   
DEBT SECURITIES. The Strategic Fixed Income, Growth, Growth and Income, Global
Growth, Global Income and Asset Allocation Portfolios all may invest a
substantial portion of their assets in debt securities rated within any one of
the four highest grades assigned by S&P or Moody's or assigned a comparable
rating by another NRSRO (commonly referred to as "investment grade debt
securities"). Debt securities rated Baa by Moody's or BBB by S&P are investment
grade, although Moody's considers securities rated Baa to have speculative
characteristics. Changes in economic conditions or other circumstances are more
likely to lead to a weakened capacity for such securities to make principal and
interest payments than is the case for higher grade debt securities. The Asset
Allocation Growth and Income and Growth Portfolios may invest in non-investment
grade convertible debt securities The Strategic Fixed Income Portfolio may
invest in non-investment grade convertible and non-convertible debt securities
and Global Income Portfolio may invest in non-investment grade sovereign debt
securities. Debt securities rated below investment grade are deemed by these
NRSROs to be predominantly speculative with respect to the issuer's capacity to
pay interest and repay principal and may involve major risk exposures to
adverse conditions. Such securities are commonly referred to as "junk bonds."
In the event that, due to the downgrade of one or more debt securities, a
Portfolio holds securities rated below investment grade in an amount in excess
of the percentage permitted under these investment policies, the Portfolio will
engage in an orderly disposition of these securities to the extent necessary to
reduce the Portfolio's holdings to the specified percentage. All Portfolios are
permitted to purchase debt securities that are not rated by S&P, Moody's or
another NRSRO but that Mitchell Hutchins or the sub-adviser determines to be of
comparable quality to that of rated securities in which such Portfolio may
invest. Such securities are included in the computation of any percentage
limitations applicable to the comparable rated securities.     
   
The market value of debt securities generally varies inversely with the
interest rate changes. Ratings of debt securities represent the rating agency's
opinion regarding their quality, are not a guarantee of quality and may be
reduced after a Portfolio has acquired the security. Mitchell Hutchins or the
applicable sub-adviser will consider such an event in determining whether the
Portfolio should continue to hold the security but the Portfolio is not
required to dispose of it. Credit ratings attempt to evaluate the safety of
principal and interest payments and do not evaluate the risks of fluctuations
in market value. Also, rating agencies may fail to make timely changes in
response to subsequent events, so that an issuer's financial condition may be
better or worse than the rating indicates.     
 
Lower rated debt securities generally offer a higher current yield than that
available from higher grade issues, but they involve higher risks, in that they
are especially subject to adverse changes in general economic conditions and in
the industries in which the issuers are engaged, to changes in the financial
condition of the issuers and to price fluctuation in response to changes in
interest rates. During periods of economic downturn or rising interest rates,
highly leveraged issuers may experience financial stress which could adversely
affect their ability to make payments of principal and interest and increase
the possibility of default. In addition, such issuers may not have more
traditional methods of financing available to them, and may be unable to repay
debt at maturity by refinancing. The risk of loss due to default by such
issuers is significantly greater because such securities frequently are
unsecured and subordinated to the prior payment of senior indebtedness.
 
 
                                     PW 17
<PAGE>
 
The market for lower rated securities has expanded rapidly in recent years, and
its growth paralleled a long economic expansion. In the past, the prices of
many lower rated debt securities declined substantially, reflecting an
expectation that many issuers of such securities might experience financial
difficulties. As a result, the yields on lower rated debt securities rose
dramatically, but such higher yields did not reflect the value of the income
stream that holders of such securities expected, but rather the risk that
holders of such securities could lose a substantial portion of their value as a
result of the issuers' financial restructuring or default. There can be no
assurance that such declines will not recur. The market for lower rated debt
securities generally is thinner and less active than that for higher quality
securities, which may limit a Portfolio's ability to sell such securities at
fair value in response to changes in the economy or the financial markets.
Adverse publicity and investor perceptions, whether or not based on fundamental
analysis, may also decrease the values and liquidity of lower rated securities,
especially in a thinly traded market.
   
DURATION. Duration is a measure of the expected life of a fixed income security
that was developed as a more precise alternative to the concept of "term to
maturity." Duration incorporates a bond's yield, coupon interest payments,
final maturity and call features into one measure. Duration is one of the
fundamental tools used by the sub-adviser in portfolio selection for the
Strategic Fixed Income Portfolio.     
   
Traditionally, a debt security's "term to maturity" has been used as a proxy
for the sensitivity of the security's price to changes in interest rates (which
is the "interest rate risk" or "volatility" of the security). However, "term to
maturity" measures only the time until a debt security provides its final
payments, taking no account of the pattern of the security's payments prior to
maturity. Duration is a measure of the expected life of a fixed income security
on a present value basis. Duration takes the length of the time intervals
between the present time and the time that the interest and principal payments
are scheduled or, in the case of a callable bond, expected to be received, and
weights them by the present values of the cash to be received at each future
point in time. For any fixed income security with interest payments occurring
prior to the payment of principal, duration is always less than maturity. In
general, all other things being equal, the lower the stated or coupon rate of
interest of a fixed income security, the longer the duration of the security;
conversely, the higher the stated or coupon rate of interest of a fixed income
security, the shorter the duration of the security.     
          
Futures, options and options on futures have duration which in general, are
closely related to the duration of the securities which underlie them. Holding
long futures or call option positions (backed by a segregated account of cash
and cash equivalents) will lengthen a Portfolio's duration by approximately the
same amount that selling an equivalent amount of the underlying securities
would.     
   
Short futures or put option positions have durations roughly equal to the
negative duration of the securities that underlie these positions, and have the
effect of reducing portfolio duration by approximately the same amount that
selling an equivalent amount of the underlying securities would.     
   
There are some situations where even the standard duration calculation does not
properly reflect the interest rate exposure of a security. For example,
floating and variable rate securities often have final maturities of ten or
more years; however, their interest rate exposure corresponds to the frequency
of the coupon reset. Another example where the interest rate exposure is not
properly captured by duration is the case of mortgage pass-through securities.
The stated final maturity of such securities is generally 30 years, but current
prepayment rates are more critical in determining the securities' interest rate
exposure. In these and other similar situations, the sub-adviser will use more
sophisticated analytical techniques that incorporate the economic life of a
security into the determination of its interest rate exposure.

CONVERTIBLE SECURITIES. A convertible security is a bond, debenture, note,
preferred stock or other security that may be converted into or exchanged for a
prescribed amount of common stock of the same or a different issuer within a
particular period of time at a specified price or formula. A convertible
security entitles the holder to receive interest paid or accrued on debt or
dividends paid on preferred stock until the convertible security matures or is
redeemed, converted or exchanged. Convertible securities have unique investment
characteristics in that they generally (1) have higher yields than common
stocks, but lower yields than comparable non-convertible securities, (2) are
less subject to fluctuation in value than the underlying stock because they
have fixed income characteristics, and (3) provide the potential for capital
appreciation if the market price of the underlying common stock increases.
While no securities investment is without some risk, investments in convertible
securities generally entail less risk than the issuer's common stock, although
the extent to which such risk is reduced depends in large measure upon the
degree to which the convertible security sells above its value as a fixed
income security.     
   
ZERO COUPON AND PAYMENT-IN KIND SECURITIES. Strategic Fixed Income, Global
Income and Asset Allocation Portfolios may invest in certain zero coupon
securities that are "stripped" U.S. Treasury notes and bonds. The Strategic
Fixed Income Portfolio also may invest in zero coupon securities of corporate
issuers and other securities that are issued with original issue discount
("OID") and payment-in-kind ("PIK") securities. Federal tax law requires that a
holder of a security with OID accrue a portion of the OID on the security as
income each year, even though the holder may receive no interest payment on the
security during the year. Accordingly, although the investing Portfolio will
receive no payments on its zero coupon securities prior to their maturity or
disposition, it will have income attributable to such securities. Similarly,
while PIK securities may pay interest in the form of additional securities
rather than cash, that interest must be included in the annual income of
Strategic Fixed Income Portfolio.     
   
Companies such as the Portfolios, which seek to qualify for pass-through
federal income tax treatment as regulated investment companies ("RIC"), must
distribute substantially all of their net investment income each year,
including non-cash income. Accordingly, each Portfolio will be required to
include in its dividends an amount equal to the income attributable to its zero
coupon, other OID and PIK securities. Those dividends will be paid from the
cash assets of a Portfolio or by liquidation of portfolio securities, if
necessary, at a time when the Portfolio otherwise might not have done so. Zero
coupon and PIK securities usually trade at a substantial discount from their
face or par value and will be subject to greater fluctuations of market value
in response to changing interest rates than debt obligations of comparable
maturities that make current distributions of interest in cash.     
   
LENDING OF PORTFOLIO SECURITIES. Each Portfolio (other than the Money Market
Portfolio) is authorized to lend up to 10% (33 1/3% for Strategic Fixed Income
Portfolio) of the total value of its portfolio securities to broker-dealers or
institutional investors that Mitchell Hutchins or the applicable sub-adviser
deems qualified. Lending securities enables a Portfolio to earn additional
income, but could result in a loss or delay in recovering the Portfolio's
securities.     
   
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. Each Portfolio may purchase
securities on a "when-issued" basis or may purchase or sell securities for
delayed delivery. In when-issued or delayed delivery transactions, delivery of
the securities occurs beyond normal settlement periods, but a Portfolio would
not pay for such securities or start earning interest on them until they are
delivered. However, when a Portfolio purchases securities on a when-issued or
delayed delivery basis, it immediately assumes the risks of ownership,
including the risk of price fluctuation. Failure by a counter party to deliver
a security purchased on a when-issued or delayed delivery basis may result in a
loss or missed opportunity to make an alternative investment. Depending on
market conditions, a Portfolio's when-issued and delayed-delivery purchase
commitments could cause its net asset value per share to be more volatile,
because such securities may increase the amount by which the     
 
                                     PW 19
<PAGE>
 
Portfolio's total assets, including the value of when-issued and delayed-
delivery securities held by the Portfolio, exceed its net assets.
   
REPURCHASE AGREEMENTS. Each Portfolio may enter into repurchase agreements.
Repurchase agreements are transactions in which a Portfolio purchases
securities from a bank or recognized securities dealer and simultaneously
commits to resell the securities to the bank or dealer at an agreed-upon date
and price reflecting a market rate of interest unrelated to the coupon rate or
maturity of the purchased securities. Repurchase agreements carry certain risks
not associated with direct investments in securities, including possible
decline in the market value of the underlying securities and delays and costs
to a Portfolio if the other party to the repurchase agreement becomes
insolvent, each Portfolio intends to enter into repurchase agreements only with
banks and dealers in transactions believed by Mitchell Hutchins or the
applicable sub-adviser to present minimal credit risks in accordance with
guidelines established by the Fund's board of trustees.     
   
REVERSE REPURCHASE AGREEMENTS AND DOLLAR ROLLS. The Strategic Fixed Income
Global Income Portfolios may enter into reverse repurchase agreements with
banks and broker-dealers. Such agreements involve the sale of securities held
by the Portfolio subject to the Portfolio's agreement to repurchase the
securities at an agreed-upon date and price. Such agreements are considered to
be borrowings and for the Global Income Portfolio may be entered into only for
temporary purposes. The market value of securities sold under reverse
repurchase agreements typically is greater than the proceeds of the sale, and
accordingly, the market value of the securities sold is likely to be greater
than the value of the securities in which the Portfolio invests those proceeds.
Thus, reverse repurchase agreements involve the risk that the buyer of the
securities sold by the Portfolio might be unable to deliver them when the
Portfolio seeks to repurchase. In the event the buyer of securities under a
reverse repurchase agreement files for bankruptcy or becomes insolvent, such
buyer or its trustee or receiver may receive an extension of time to determine
whether to enforce the Portfolio's obligation to repurchase the securities and
the Portfolio's use of the proceeds of the reverse repurchase agreement may
effectively be restricted pending such decision.     
   
The Strategic Fixed Income may enter into dollar rolls, in which the Portfolio
sells mortgage-backed or other securities for delivery in the current month and
simultaneously contracts to repurchase substantially similar securities on a
specified future date. In the case of dollar rolls involving mortgage-backed
securities, the mortgage-backed securities that are repurchased will be of the
same type, and will have the same interest rate and maturity, as those sold but
generally will be supported by different pools of mortgages with substantially
similar prepayment characteristics. The Portfolio forgoes principal and
interest paid during the roll period on the securities sold in a dollar roll,
but the Portfolio is compensated by the difference between the current sales
price and the lower price for the future purchase as well as by any interest
earned on the proceeds of the securities sold. The Portfolio also could be
compensated through the receipt of fee income equivalent to a lower forward
price.     
   
The dollar rolls and reverse repurchase agreements entered into by the
Strategic Fixed Income Portfolio normally will be arbitrage transactions in
which the Portfolio will maintain an offsetting position in securities that
mature on or before the settlement date on the related dollar roll or reverse
repurchase agreement or in repurchase agreements that mature in no more than
seven days. Because the Portfolio will invest the proceeds of its borrowings
and earn those investments, these transactions involve leverage. However,
because the borrowing proceeds are invested in short-term, high quality debt
securities or repurchase agreements, as described above, Mitchell Hutchins or
the applicable sub-adviser believes that such arbitrage transactions do not
present the risks to the Portfolio that are associated with other types of
leverage.     
 
 
                                     PW 20
<PAGE>
 
   
Dollar rolls and reverse repurchase agreements are considered to be borrowings
and, accordingly, are subject to the respective Portfolio's limitations on
borrowings, which restricts the aggregate of such transactions (plus any other
borrowings) to 10% of the Global Income Portfolio's total assets (33 1/3% for
Strategic Fixed Income Fund). A Portfolio will not enter into dollar rolls or
reverse repurchase agreements, other than in arbitrage transactions as
described above, in an aggregate amount in excess of 5% of the Portfolio's
total assets. The Strategic Fixed Income Portfolio has no present intention to
enter into dollar rolls other than in such arbitrage transactions, and neither
Portfolio has any present intention to enter into reverse repurchase agreements
other than in such arbitrage transactions or for temporary or emergency
purposes.     
   
HEDGING AND RELATED INCOME STRATEGIES. Except for the Money Market and Asset
Allocation Portfolios, each Portfolio may use options (both exchange-traded and
OTC) and futures contracts to attempt to enhance income and may attempt to
reduce the overall risk of its investments (hedge) by using options and futures
contracts, although the High Grade Fixed Income and Aggressive Growth
Portfolios have no intention of doing so during the coming year. The Strategic
Fixed Income, Global Income and Global Growth Portfolios may also use forward
currency contracts. A Portfolio's ability to use these strategies may be
limited by market conditions, regulatory limits and tax considerations.
Appendix B to this Prospectus describes the hedging instruments that the
Portfolios may use. The Statement of Additional Information contains further
information on these strategies.     
   
Each Portfolio eligible to use hedging and related income strategies may write
(sell) covered call and put options, buy call and put options on securities in
which it is authorized to invest and on stock indexes, sell stock index or
interest rate futures contracts and buy put and call options and write covered
call options on such futures contracts. The Global Growth, Global Income and
Strategic Fixed Income Portfolios each may write covered call options and buy
put and call options on foreign currencies, buy or sell foreign currency
futures contracts, buy put and call options and write covered call options on
such contracts. These Portfolios may enter into forward currency contracts for
the purchase or sale of a specified currency at a specified future date either
with respect to specific transactions or with respect to portfolio positions.
For example, when Mitchell Hutchins or the applicable sub-adviser anticipates
making a currency exchange transaction in connection with the purchase or sale
of a security, a Portfolio may enter into a forward contract in order to set
the exchange rate at which the transaction will be made. A Portfolio also may
enter into a forward contract to sell an amount of a foreign currency
approximating the value of some or all of the Portfolio's securities positions
denominated in such currency. A Portfolio may use forward contracts in one
currency or a basket of currencies to hedge against fluctuations in the value
of another currency when Mitchell Hutchins or the applicable sub-adviser
anticipates that there will be a correlation between the two and may use
forward currency contracts to shift a Portfolio's exposure to foreign currency
fluctuations from one country to another. The purpose of entering into these
contracts is to minimize the risk to a Portfolio from adverse changes in the
relationship between the U.S. dollar and foreign currencies.     
   
The Strategic Fixed Income and Global Income Portfolios may enter into interest
rate protection transactions, including interest rate swaps and interest rate
caps, collars and floors, for hedging purposes. For example, each Portfolio may
enter into interest rate protection transactions to preserve a return or spread
on a particular investment or portion of its portfolio or to protect against
any increase in the price of securities the Portfolio anticipates purchasing at
a later date. The Portfolio will enter into interest rate protection
transactions only with banks and recognized securities dealers believed by
Mitchell Hutchins or the applicable sub-adviser to present minimal credit risks
in accordance with guidelines established by the Fund's board of trustees.     
   
A Portfolio might not employ any of the strategies described above, and there
can be no assurance that any strategy used will succeed. If Mitchell Hutchins
or the applicable sub-adviser incorrectly     
 
                                     PW 21
<PAGE>
 
forecasts interest rates, market values or other economic factors for a
Portfolio, the Portfolio would be in a better position had it not hedged at
all. The use of these strategies involves certain special risks, including (1)
the fact that skills needed to use hedging instruments are different from those
needed to select the Portfolios' securities, (2) possible imperfect
correlation, or even no correlation, between price movements of hedging
instruments and price movements of the investments being hedged, (3) the fact
that, while hedging strategies can reduce the risk of loss, they can also
reduce the opportunity for gain, or even result in losses, by offsetting
favorable price movements in hedged investments and (4) the possible inability
of a Portfolio to purchase or sell a portfolio security at a time that
otherwise would be favorable for it to do so, or the possible need for a
Portfolio to sell a portfolio security at a disadvantageous time, due to the
need for the Portfolio to maintain "cover" or to segregate securities in
connection with hedging transactions and the possible inability of a Portfolio
to close out or to liquidate its hedged position.
 
New financial products and risk management techniques continue to be developed.
Each Portfolio may use these instruments and techniques to the extent
consistent with its investment objectives and regulatory and federal tax
considerations.
   
ILLIQUID SECURITIES. Each Portfolio may invest up to 10% of its net assets (15%
for the Strategic Fixed Income Portfolio) in illiquid securities, including
certain cover for OTC options, repurchase agreements with maturities in excess
of seven days and securities whose disposition is restricted under the federal
securities laws (other than "Rule 144A" securities which Mitchell Hutchins has
determined to be liquid under procedures approved by the Fund's board of
trustees). Rule 144A establishes a "safe harbor" from the registration
requirements of the Securities Act of 1933 ("1933 Act"). Institutional markets
for restricted securities have developed as a result of Rule 144A, providing
both readily ascertainable values for restricted securities and the ability to
liquidate an investment to satisfy share redemption orders. An insufficient
number of qualified institutional buyers interested in purchasing Rule 144A-
eligible restricted securities held by a Portfolio, however, could affect
adversely the marketability of such portfolio securities and the Portfolio
might be unable to dispose of such securities promptly or at favorable prices.
       
The Strategic Fixed Income Fund may invest in secured or unsecured fixed or
floating rate loans ("Loans") arranged through private negotiations between a
borrowing corporation and one or more financial institutions ("Lenders"). The
Portfolio's investments in Loans are expected in most instances to be in the
form of participations ("Participations") and assignments ("Assignments") of
all or a portion of Loans from third parties. Participations typically result
in the Portfolio's having a contractual relationship only with the Lender, not
with the borrower. The Portfolio has the right to receive payments of
principal, interest and any fees to which it is entitled only from the lender
selling the Participation and only upon receipt by the Lender of the payments
from the borrower. In connection with purchasing Participations, the Portfolio
generally has no direct right to enforce compliance by the borrower with the
terms of the loan agreement relating to the Loan, nor any rights of set-off
against the borrower, and the Portfolio may not benefit directly from any
collateral supporting the Loan in which it has purchased the Participation. As
a result, the Portfolio assumes the credit risk of both the borrower and the
Lender that is selling the Participation. In the event of the insolvency of the
Lender selling a Participation, the Portfolio may be treated as a general
creditor of the Lender and may not benefit from any set-off between the Lender
and the borrower. The Portfolio will acquire Participations only if the lender
interpositioned between the Portfolio and the borrower is determined by the
sub-adviser to be creditworthy.     
   
When the Strategic Fixed Income Portfolio purchases Assignments from Lenders,
it acquires direct rights against the borrower on the Loan. However, because
Assignments are arranged through private negotiations between potential
assignees and assignors, the rights and obligations acquired by the Portfolio
as the purchaser of an Assignment may differ from, and be more limited than,
those held by the assigning Lender.     
 
                                     PW 22
<PAGE>
 
   
Assignments and Participations are generally not registered under the 1933 Act
and thus are subject to the Strategic Fixed Income Portfolio's limitation to
15% of its net assets with respect to its investments in illiquid securities.
Because there is no liquid market for these securities, the Portfolio
anticipates that these securities could be sold only to a limited number of
institutional investors. The lack of a liquid secondary market will have an
adverse impact of the value of these securities and on the Portfolio's ability
to dispose of particular Assignments and Participations when necessary to meet
the Portfolio's liquidity needs or in response to a specific economic event,
such as a deterioration in the creditworthiness of the borrower.     
   
PORTFOLIO TURNOVER. The portfolio turnover rate may vary greatly from year to
year and will not be a limiting factor when Mitchell Hutchins or the applicable
sub-adviser deems portfolio changes appropriate. A higher turnover rate may
involve correspondingly greater transaction costs, which will be borne directly
by the affected Portfolio and may increase the potential for short-term capital
gains.     
   
OTHER INFORMATION. When Mitchell Hutchins or the applicable sub-adviser
believes unusual circumstances warrant a defensive posture, each Portfolio
temporarily may commit all or any portion of its assets to cash, U.S.
government securities or money market instruments, including repurchase
agreements. The Global Growth, Global Income and Strategic Fixed Income
Portfolios may hold cash in U.S. dollars or foreign currencies and money market
instruments of U.S. or foreign issuers, including instruments backed by the
U.S. or foreign governments, their agencies or instrumentalities and repurchase
agreements secured thereby. Each Portfolio may borrow money for temporary
purposes but not in excess of 10% of its total assets (33 1/3% for the
Strategic Fixed Income Portfolio).     
 
Each Portfolio's investment objective and certain investment limitations, as
described in the Statement of Additional Information, are fundamental policies
that may not be changed without shareholder approval. All other investment
policies may be changed by the Fund's board of trustees without shareholder
approval.
 
                      PURCHASES, REDEMPTIONS AND EXCHANGES
 
Shares of the Portfolios are offered only to the insurance company separate
accounts that fund the Contracts. All such shares may be purchased or redeemed
by the separate accounts without any sales or redemption charge at net asset
value. Proceeds from redemptions in any of the Portfolios will be paid on or
before the seventh day following the request for redemption by a Contract
holder.
 
A separate account may exchange shares of one Portfolio for shares of another
Portfolio at their relative net asset values per share.
 
             DIVIDENDS, OTHER DISTRIBUTIONS AND FEDERAL INCOME TAX
 
DIVIDENDS AND OTHER DISTRIBUTIONS. With the exception of the Money Market
Portfolio, each Portfolio distributes all of its net investment income as
dividends to its shareholders shortly after the close of the Fund's fiscal year
on December 31. At the same time, those Portfolios also distribute to their
shareholders all of their net short-term capital gain and their net capital
gain (the excess of net long-term capital gain over net short-term capital
loss) and any net gains from foreign currency transactions. Those Portfolios
may make a second distribution of net investment income, net short-term capital
gain, net capital gain and net gains from foreign currency transactions if
necessary to avoid income tax.
 
                                     PW 23
<PAGE>
 
The Money Market Portfolio declares as dividends on each Business Day all of
its net investment income, payable to shareholders of record as of the close of
regular trading on the New York Stock Exchange ("NYSE") (currently 4:00 p.m.,
eastern time) on the preceding Business Day; those dividends are paid monthly.
A "Business Day" is any day, Monday through Friday, on which the NYSE is open
for business. Net investment income of the Portfolio consists of accrued
interest and earned discount (including both original issue and market
discounts), less amortization of market premium and applicable expenses. Net
investment income is calculated and dividends are declared immediately prior to
the determination of net asset value per share. The Portfolio generally
distributes to its shareholders any net short-term capital gain annually after
the end of its fiscal year on December 31 but may make more frequent
distributions of that gain if necessary to maintain its net asset value per
share at $1.00 or to avoid income tax. The Portfolio does not expect to realize
long-term capital gain and thus does not anticipate any distributions of net
capital gain.
 
Dividends and capital gain distributions from a Portfolio are paid in
additional shares of that Portfolio at net asset value per share, unless the
Fund's transfer agent is instructed otherwise. See the applicable Contract
prospectus for information regarding the federal income tax treatment of
distributions to the separate accounts.
 
FEDERAL INCOME TAX. Each Portfolio intends to continue to qualify for treatment
as a regulated investment company ("RIC") under Subchapter M of the Internal
Revenue Code so that it will be relieved of federal income tax on that part of
its investment company taxable income (consisting generally of net investment
income, net gains from certain foreign currency transactions and net short-term
capital gain) and net capital gain that is distributed to its shareholders.
 
Dividends and other distributions declared by a Portfolio in October, November
or December of any year and payable to shareholders of record on a date in any
of those months will be deemed to have been paid by the Portfolio and received
by the shareholders on December 31 of that year if the distributions are paid
by the Portfolio during the succeeding January.
 
Portfolio shares are offered only to insurance company separate accounts that
fund variable annuity and variable life insurance contracts. Under the Internal
Revenue Code, no tax is imposed on an insurance company with respect to income
of a qualifying separate account properly allocable to the value of eligible
variable annuity or variable life insurance contracts. See the applicable
Contract prospectus for a discussion of the federal income tax status of (1)
the separate accounts that purchase and hold shares of the Portfolios and (2)
the holders of Contracts funded through those accounts.
   
Each Portfolio intends to continue to comply with the diversification
requirements imposed by section 817(h) of the Internal Revenue Code and the
regulations thereunder. These requirements, which are in addition to the
diversification requirements imposed on the Portfolios by the 1940 Act and
Subchapter M, place certain limitations on the assets of each separate
account--and, because section 817(h) and those regulations treat the assets of
each Portfolio as assets of the related separate account, of each Portfolio--
that may be invested in securities of a single issuer. Specifically, the
regulations provide that, except as permitted by the "safe harbor" described
below, as of the end of each calendar quarter or within 30 days thereafter no
more than 55% of the total assets of a Portfolio may be represented by any one
investment, no more than 70% by any two investments, no more than 80% by any
three investments and no more than 90% by any four investments. For this
purpose, all securities of the same issuer are considered a single investment,
and each U.S. government agency and instrumentality is considered a separate
issuer. Section 817(h) provides, as a safe harbor, that a separate account will
be treated as being adequately diversified if the diversification requirements
under Subchapter M are satisfied and no more than 55% of the value of the
account's total assets are cash and cash items, government securities and
securities of other RICs. Failure of a Portfolio to satisfy the section 817(h)
requirements would result in taxation of the insurance company issuing

the Contracts and treatment of the Contract holders other than as described in
the applicable Contract prospectus.
 
The foregoing is only a summary of some of the important federal income tax
considerations generally affecting the Portfolios and their shareholders; see
the Statement of Additional Information for a more detailed discussion.
Prospective shareholders are urged to consult their tax advisers.
 
                              VALUATION OF SHARES
   
The net asset value of each Portfolio's shares, other than the Money Market
Portfolio, fluctuates and is determined for all Portfolios as of the close of
regular trading on the NYSE (currently 4:00 p.m., eastern time) on each
Business Day. For each Portfolio other than the Money Market Portfolio, net
asset value per share is computed by dividing the value of the securities held
by the Portfolio plus any cash or other assets minus all liabilities by the
total number of Portfolio shares outstanding. Except for the Money Market
Portfolio, each Portfolio values its assets based on the current market value
where market quotations are readily available. If such value cannot be
established, the assets are valued at fair value as determined in good faith by
or under the direction of the Fund's board of trustees. The amortized cost
method of valuation generally is used to value debt obligations with 60 days or
less remaining to maturity, unless the board of trustees determines that this
does not represent fair value. All investments denominated in foreign currency
are valued daily in U.S. dollars on the basis of the then-prevailing exchange
rates.     
 
The Money Market Portfolio intends to use its best efforts to maintain its net
asset value at $1.00 per share. The value of each share of this Portfolio is
computed by dividing its net assets by the number of its outstanding shares.
"Net assets" equals the value of the investments and other assets minus its
liabilities. The Money Market Portfolio values its portfolio securities using
the amortized cost method of valuation, under which market value is
approximated by amortizing the difference between the acquisition cost and
value at maturity of the instrument on a straight-line basis over its remaining
life. All cash, receivables and current payables are generally carried at their
face value. Other assets are valued at fair value as determined in good faith
by or under the direction of the Fund's board of trustees. All investments
denominated in foreign currencies are valued daily in U.S. dollars based on the
then-prevailing exchange rate. It should be recognized that judgment plays a
greater role in valuing lower rated debt securities because there is less
reliable, objective data available.
 
                                   MANAGEMENT
   
The Fund's board of trustees, as part of its overall management responsibility,
oversees various organizations responsible for each Portfolio's day-to-day
management. Mitchell Hutchins, the investment adviser and administrator for
each Portfolio, makes and implements all investment decisions and supervises
all aspects of the operations of the Money Market, Growth, Growth and Income,
Global Income and Asset Allocation Portfolios. Mitchell Hutchins supervises the
activities of PIMCO and GEIM, the sub-advisers for the Strategic Fixed Income
and Global Growth Portfolios, respectively, and supervises all other aspects of
these Portfolios operations. PIMCO and GEIM as sub-advisers for the Strategic
Fixed Income and Global Growth Portfolios, respectively, makes and implements
all investment decisions for these Portfolios. Brokerage transactions for the
Portfolios may be conducted through PaineWebber or its affiliates, in
accordance with procedures adopted by the Fund's board of trustees.

ALLOCATION PORTFOLIO IS HIGHER THAN THAT PAID BY FUNDS WITH SIMILAR INVESTMENT
OBJECTIVES AND POLICIES TO THEIR ADVISERS.
   
The Portfolios also incur other expenses in their operations. For the fiscal

net assets for each Portfolio were 0.88% for the Money Market Portfolio, 1.00%
for the Growth Portfolio, 1.48% for the Global Growth Portfolio, 1.17% for the
Global Income Portfolio, 1.03% for the Asset Allocation Portfolio, 0.89% for
the Strategic Fixed Income Portfolio and 1.35% for the Growth and Income

GINNIE MAE CERTIFICATES. Ginnie Mae guarantees certain mortgage pass-through
certificates ("Ginnie Mae certificates") that are issued by Private Mortgage
Lenders and that represent ownership interests in individual pools of
residential mortgage loans. These securities are designed to provide monthly
payments of interest and principal to the investor. Timely payment of interest
and principal (but not the market value of the security itself) is backed by
the full faith and credit of the U.S. government. Each mortgagor's monthly
payments to his lending institution on his residential mortgage are "passed
through" to certificateholders such as a Portfolio. Mortgage pools consist of
whole mortgage loans or participations in loans. The terms and characteristics
of the mortgage instruments are generally uniform within a pool but may vary
among pools. Lending institutions that originate mortgages for the pools are
subject to certain standards, including credit and other underwriting criteria
for individual mortgages included in the pools.
 
FANNIE MAE CERTIFICATES. Fannie Mae facilitates a national secondary market in
residential mortgage loans insured or guaranteed by U.S. government agencies
and in privately insured or uninsured residential mortgage loans (sometimes
referred to as "conventional mortgage loans" or "conventional loans") through
its mortgage purchase and mortgage-backed securities sales activities. Fannie
Mae issues guaranteed mortgage pass-through certificates ("Fannie Mae
certificates"), which represent pro rata shares of all interest and principal
payments made and owed on the underlying pools. Fannie Mae guarantees timely
payment of interest and principal (but not the market value of the security
itself) on Fannie Mae certificates. The Fannie Mae guarantee is not backed by
the full faith and credit of the U.S. government.
 
FREDDIE MAC CERTIFICATES. Freddie Mac also facilitates a national secondary
market for conventional residential and U.S. government-issued mortgage loans
through its mortgage purchase and mortgage-backed securities sales activities.
Freddie Mac issues two types of mortgage pass-through securities: mortgage
participation certificates ("PCs") and guaranteed mortgage certificates
("GMCs"). Each PC represents a pro rata share of all interest and principal
payments made and owed on the underlying pool. Freddie Mac generally guarantees
timely monthly payment of interest on PCs and the ultimate payment of
principal, but it also has a PC program under which it guarantees timely
payment of both principal and interest. GMCs also represent a pro rata interest
in a pool of mortgages. These instruments, however, pay interest semi-annually
and return principal once a year in guaranteed minimum payments. Freddie Mac
does not guarantee the market value of the security itself. The Freddie Mac
guarantee is not backed by full faith and credit of the U.S. government.
 
PRIVATE, RTC AND SIMILAR MORTGAGE-BACKED SECURITIES. Mortgage-backed securities
issued by Private Mortgage Lenders are structured similarly to the CMOs or
single class mortgage-backed securities issued or guaranteed by Ginnie Mae,
Fannie Mae and Freddie Mac. Such mortgage-backed securities may be supported by
pools of U.S. government or agency insured or guaranteed mortgage loans or by
other mortgage-backed securities issued by a government agency or
instrumentality, but they generally are supported by pools of conventional
(i.e., non-government guaranteed or insured) mortgage loans. Since such
mortgage-backed securities normally are not guaranteed by an entity having the
credit standing of Ginnie Mae, Fannie Mae or Freddie Mac, they normally are
structured with one or more types of credit enhancement. See "--Types of Credit
Enhancement." Such credit enhancements do not protect investors from changes in
market value.
 
The Resolution Trust Corporation ("RTC"), which was organized by the U.S.
government in connection with the savings and loan crisis, holds assets of
failed savings associations as either a conservator or receiver for such
associations, or it acquires such assets in its corporate capacity. These
assets include, among other things, single family and multi-family mortgage
loans, as well as commercial mortgage loans. In order to dispose of such assets
in an orderly manner, RTC has established a vehicle registered with the SEC
through which it sells mortgage-backed securities. RTC
 
                                     PW 30
<PAGE>
 
mortgage-backed securities represent pro rata interests in pools of mortgage
loans that RTC holds or has acquired, as described above, and are supported by
one or more of the types of private credit enhancements used by Private
Mortgage Lenders.
 
COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTI-CLASS MORTGAGE PASS-THROUGHS.
CMOs are debt obligations that are collateralized either by mortgage loans,
mortgage pass-through securities or other CMOs (such collateral collectively
being called "Mortgage Assets"). CMOs may be issued by Private Mortgage Lenders
or by government entities such as Fannie Mae or Freddie Mac. Multi-class
mortgage pass-through securities are interests in trusts that are comprised of
Mortgage Assets and that have multiple classes similar to those of CMOs. Unless
the context indicates otherwise, references herein to CMOs include multi-class
mortgage pass-through securities. Payments of principal of and interest on the
Mortgage Assets (and in the case of CMO's any reinvestment income thereon)
provide the funds to pay debt service on the CMOs or to make scheduled
distributions on the multi-class mortgage pass-through securities. In a CMO, a
series of bonds or certificates is issued in multiple classes. Each class of
CMO, also referred to as a "tranche," is issued at a specific fixed or floating
coupon rate and has a stated maturity or final distribution date. Principal
prepayments on the Mortgage Assets may cause CMOs to be retired substantially
earlier than their stated maturities or final distribution dates. Interest is
paid or accrues on all classes of a CMO (other than any principal only or PO
class) on a monthly, quarterly or semi-annual basis. The principal and interest
on the Mortgage Assets may be allocated among the several classes of a CMO in
many ways. In one structure, payments of principal, including any principal
prepayments, on the Mortgage Assets are applied to the classes of a CMO in
order of their respective stated maturities or final distribution dates so that
no payment of principal will be made on any class of the CMO until all other
classes having an earlier stated maturity or final distribution date have been
paid in full. In some CMO structures, all or a portion of the interest
attributable to one or more of the CMO classes may be added to the principal
amounts attributable to such classes, rather than passed through to
certificateholders on a current basis, until other classes of the CMO are paid
in full.
 
  Parallel pay CMOs are structured to provide payments of principal on each
payment date to more than one class. These simultaneous payments are taken into
account in calculating the stated maturity date or final distribution date of
each class, which, as with other CMO structures, must be retired by its stated
maturity date or final distribution date but may be retired earlier.
 
ARM AND FLOATING RATE MORTGAGE-BACKED SECURITIES. ARM mortgage-backed
securities are mortgage-backed securities that represent a right to receive
interest payments at a rate that is adjusted to reflect the interest earned on
a pool of mortgage loans bearing variable or adjustable rates of interest (such
mortgage loans are referred to as "ARMs"). Floating rate mortgage-backed
securities are classes of mortgage-backed securities that have been structured
to represent the right to receive interest payments at rates that fluctuate in
accordance with an index but that generally are supported by pools comprised of
fixed-rate mortgage loans. Because the interest rates on ARM and floating rate
mortgage-backed securities are reset in response to changes in a specified
market index, the values of such securities tend to be less sensitive to
interest rate fluctuations than the values of fixed-rate securities.
 
TYPES OF CREDIT ENHANCEMENT. To lessen the effect of failures by obligors on
Mortgage Assets to make payments, mortgage-backed securities may contain
elements of credit enhancement. Such credit enhancement falls into two
categories: (1) liquidity protection; and (2) protection against losses
resulting after default by an obligor on the underlying assets and collection
of all amounts recoverable directly from the obligor and through liquidation of
the collateral. Liquidity protection refers to the provision of advances,
generally by the entity administering the pool of assets (usually the bank,
savings association or mortgage banker that transferred the underlying loans to
the issuer of the security), to ensure that the receipt of payments on the
underlying pool occurs in a timely fashion. Protection against losses resulting
after default and liquidation ensures ultimate payment
 
                                     PW 31
<PAGE>
 
of the obligations on at least a portion of the assets in the pool. Such
protection may be provided through guarantees, insurance policies or letters of
credit obtained by the issuer or sponsor from third parties, through various
means of structuring the transaction or through a combination of such
approaches. The Portfolios will not pay any additional fees for such credit
enhancement, although the existence of credit enhancement may increase the
price of a security.
 
Examples of credit enhancement arising out of the structure of the transaction
include "senior-subordinated securities" (multiple class securities with one or
more classes subordinate to other classes as to the payment of principal
thereof and interest thereon, with the result that defaults on the underlying
assets are borne first by the holders of the subordinated class), creation of
"spread accounts" or "reserve funds" (where cash or investments, sometimes
funded from a portion of the payments on the underlying assets, are held in
reserve against future losses) and "over-collateralization" (where the
scheduled payments on, or the principal amount of, the underlying assets exceed
that required to make payment of the securities and pay any servicing or other
fees). The degree of credit enhancement provided for each issue generally is
based on historical information regarding the level of credit risk associated
with the underlying assets. Delinquency or loss in excess of that anticipated
could adversely affect the return on an investment in such a security.
 
SPECIALLY STRUCTURED CMOS AND NEW TYPE OF MORTGAGE-BACKED SECURITIES. The
Portfolios may invest in IOs, POs, inverse floating rate CMOs and other
specially structured CMO classes. See "Risk Factors and Other Investment
Policies--Risks of Mortgage- and Asset-Backed Securities."
 
New types of mortgage-backed securities are developed and marketed from time to
time and, consistent with their investment limitations, the Portfolios expect
to invest in those new types of mortgage-backed securities that Mitchell
Hutchins believes may assist a Portfolio in achieving its investment objective.
Similarly, the Portfolios may invest in mortgage-backed securities issued by
new or existing governmental or private issuers other than those identified
above. The Fund's prospectus or statement of additional information will be
supplemented to the extent that new types of mortgage-backed securities or
those issued by issuers other than those identified above involve materially
different risks than the securities or issuers described herein.

                                                                      APPENDIX B
 
                     HEDGING AND OPTION INCOME INSTRUMENTS
 
Certain Portfolios may use the following hedging instruments:
 
  OPTIONS ON EQUITY AND DEBT SECURITIES AND FOREIGN CURRENCIES--A call option
  is a short-term contract pursuant to which the purchaser of the option, in
  return for a premium, has the right to buy the security or currency
  underlying the option at a specified price at any time during the term of
  the option. The writer of the call option, who receives the premium, has
  the obligation, upon exercise of the option during the option term, to
  deliver the underlying security or currency against payment of the exercise
  price. A put option is a similar contract that gives its purchaser, in
  return for a premium, the right to sell the underlying security or currency
  at a specified price during the option term. The writer of the put option,
  who receives the premium, has the obligation, upon exercise of the option
  during the option term, to buy the underlying security or currency at the
  exercise price.
 
  OPTIONS ON STOCK INDEXES--A stock index assigns relative values to the
  stocks included in the index and fluctuates with changes in the market
  values of those stocks. A stock index option operates in the same way as a
  more traditional stock option, except that exercise of a stock index option
  is effected with cash payment and does not involve delivery of securities.
  Thus, upon exercise of a stock index option, the purchaser will realize,
  and the writer will pay, an amount based on the difference between the
  exercise price and the closing price of the stock index.
 
  STOCK INDEX FUTURES CONTRACTS--A stock index futures contract is a
  bilateral agreement pursuant to which one party agrees to accept, and the
  other party agrees to make, delivery of an amount of cash equal to a
  specified dollar amount times the difference between the stock index value
  at the close of trading of the contract and the price at which the futures
  contract is originally struck. No physical delivery of the stocks
  comprising the index is made. Generally, contracts are closed out prior to
  the expiration date of the contract.
 
  INTEREST RATE AND FOREIGN CURRENCY FUTURES CONTRACTS--Interest rate and
  foreign currency futures contracts are bilateral agreements pursuant to
  which one party agrees to make, and the other party agrees to accept,
  delivery of a specified type of debt security or currency at a specified
  future time and at a specified price. Although such futures contracts by
  their terms call for actual delivery or acceptance of debt securities or
  currency, in most cases the contracts are closed out before the settlement
  date without the making or taking of delivery.
 
  OPTIONS ON FUTURES CONTRACTS--Options on futures contracts are similar to
  options on securities or currency, except that an option on a futures
  contract gives the purchaser the right, in return for the premium, 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), rather than to purchase
  or sell a security or currency, at a specified price at any time during the
  option term. Upon exercise of the option, the delivery of the futures
  position to the holder of the option will be accompanied by delivery of the
  accumulated balance that represents the amount by which the market price of
  the futures contract 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 future. The
  writer of an option, upon exercise, will assume a short position in the
  case of a call and a long position in the case of a put.
 
  FORWARD CURRENCY CONTRACTS--A forward currency contract involves an
  obligation to purchase or sell a specific currency at a specified future
  date, which may be any fixed number of days from the contract date agreed
  upon by the parties, at a price set at the time the contract is entered
  into.

                      INVESTMENT POLICIES AND LIMITATIONS
 
  The following supplements the information contained in the Fund's Prospectus
concerning the investment policies and limitations of its ten Portfolios.
   
  SPECIAL CONSIDERATIONS RELATING TO FOREIGN SECURITIES. As noted in the
Prospectus, the Global Income Portfolio, Global Growth Portfolio and Strategic
Fixed Income Portfolio each invests in securities of foreign issuers. In
addition, the High Grade Fixed Income Portfolio, Asset Allocation Portfolio,
Growth and Income Portfolio, Growth Portfolio and Aggressive Growth Portfolio
each may invest in U.S. dollar- denominated securities of foreign issuers. Many
of the foreign securities held by these Portfolios are not registered with the
Securities and Exchange Commission ("SEC"), nor are the issuers thereof subject
to its reporting requirements. Accordingly, there may be less publicly
available information concerning foreign issuers of securities held by those
Portfolios than is available concerning U.S. companies. Foreign companies are
not generally subject to uniform accounting, auditing and financial reporting
standards or to other regulatory requirements comparable to those applicable to
U.S. companies.     
   
  In addition to purchasing securities of foreign issuers in foreign markets,
the Global Income and Global Growth Portfolios may invest in American
Depository Receipts ("ADRs"), European Depository Receipts ("EDRs") or other
securities convertible into securities of companies based in foreign countries.
These securities may not necessarily be denominated in the same currency as the
securities into which they may be converted. Generally, ADRs, in registered
form, are denominated in U.S. dollars and are designed for use in the U.S.
securities markets and EDRs, in bearer form, may be denominated in other
currencies and are designed for use in European securities markets. ADRs are
receipts typically issued by a U.S. bank or trust company evidencing ownership
of the underlying securities. EDRs are European receipts evidencing a similar
arrangement. The High Grade Fixed Income, Asset Allocation, Growth and Income,
Growth and Aggressive Growth Portfolios generally invest in securities of
foreign companies only if such securities are traded in the U.S. securities
markets directly or through ADRs. For purposes of the Fund's investment
policies, ADRs and EDRs are deemed to have the same classification as the
underlying securities they represent. Thus, an ADR or EDR evidencing ownership
of common stock will be treated as common stock.     
 
  The Global Growth Portfolio anticipates that its brokerage transactions
involving securities of companies headquartered in countries other than the
United States will be conducted primarily on the principal exchanges of such
countries. Foreign security trading practices, including those involving
securities settlement where Portfolio assets may be released prior to receipt
of payment, may expose the Portfolio to increased risk in the event of a failed
trade or the insolvency of a foreign broker-dealer. Transactions on foreign
exchanges are usually subject to fixed commissions that are generally higher
than negotiated commissions on U.S. transactions, although the Portfolio will
endeavor to achieve the best net results in effecting portfolio transactions.
There is generally less government supervision and regulation of exchanges and
brokers in foreign countries than in the United States.
 
  Investment income on certain foreign securities may be subject to foreign
withholding or other taxes that could reduce the return on these securities.
Tax treaties between the United States and foreign countries, however, may
reduce or eliminate the amount of foreign taxes to which the Portfolio would be
subject.
 
  SOVEREIGN DEBT. Investment in debt securities issued by foreign governments
and their political subdivisions or agencies ("Sovereign Debt") involves
special risks. The issuer of the debt or the governmental authorities that
control the repayment of the debt may be unable or unwilling to repay principal
and/or interest when due in accordance with the terms of such debt, and the
Portfolio may have limited legal recourse in the event of a default.
 
  Sovereign Debt differs from debt obligations issued by private entities in
that, generally, remedies for defaults must be pursued in the courts of the
defaulting party. Legal recourse is therefore somewhat diminished. Political
conditions, especially a sovereign entity's willingness to meet the terms of
its debt
 
                                       3
<PAGE>
 
obligations, are of considerable significance. Also, there can be no assurance
that the holders of commercial bank debt issued by the same sovereign entity
may not contest payments to the holders of Sovereign Debt in the event of
default under commercial bank loan agreements.
 
  A sovereign debtor's willingness or ability to repay principal and interest
due in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Increased protectionism on the part of a
country's trading partners, or political changes in those countries, could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any, or the credit standing of a particular local
government or agency.
 
  The occurrence of political, social or diplomatic changes in one or more of
the countries issuing Sovereign Debt could adversely affect a Portfolio's
investments. Political changes or a deterioration of a country's domestic
economy or balance of trade may affect the willingness of countries to service
their Sovereign Debt. While Mitchell Hutchins or the applicable Sub-Adviser
manages the Portfolios' investments in a manner that is intended to minimize
the exposure to such risks, there can be no assurance that adverse political
changes will not cause a Portfolio to suffer a loss of interest or principal on
any of its holdings.
   
  FOREIGN CURRENCY TRANSACTIONS. Although each of the Strategic Fixed Income,
Global Income and Global Growth Portfolios values its assets daily in U.S.
dollars, it does not intend to convert its holdings of foreign currencies to
U.S. dollars on a daily basis. The Portfolios' foreign currencies may be held
as "foreign currency call accounts" at foreign branches of foreign or domestic
banks. These accounts bear interest at negotiated rates and are payable upon
relatively short demand periods. If a bank became insolvent, a Portfolio could
suffer a loss of some or all of the amounts deposited. The Portfolios may
convert foreign currency to U.S. dollars from time to time. Although foreign
exchange dealers generally do not charge a stated commission or fee for
conversion, the prices posted generally include a "spread," which is the
difference between the prices at which the dealers are buying and selling
foreign currencies.     
       
          
  SELECTION OF INVESTMENTS BY ASSET ALLOCATION PORTFOLIO. The money market
instruments in which the Asset Allocation Portfolio may invest include U.S.
Treasury bills and other obligations issued or guaranteed as to interest and
principal by the U.S. government, its agencies and instrumentalities;
obligations of U.S. banks (including certificates of deposit and bankers'
acceptances) having total assets at the time of purchase in excess of $1.5
billion and interest-bearing savings deposits in U.S. commercial and savings
banks in principal amounts at each such bank not greater than are fully insured
by the Federal Deposit Insurance Corporation, provided that the aggregate
amount of such deposits does not exceed 5% of the value of the Portfolio's
assets; commercial paper and other short-term corporate obligations; and
variable and floating rate securities and repurchase agreements. The Portfolio
may also hold cash.     
   
  The commercial paper and other short-term corporate obligations purchased by
the Portfolio will consist only of obligations of U.S. corporations that are
(1) rated at least Prime-2 by Moody's Investors Service ("Moody's") or A-2 by
Standard & Poor's ("S&P"), (2) comparably rated by another nationally
recognized statistical rating organization ("NRSRO") or (3) unrated and
determined by Mitchell Hutchins to be of comparable quality. These obligations
may include variable amount master demand notes, which are unsecured
obligations redeemable upon notice that permit investment of fluctuating
amounts at varying rates of interest pursuant to direct arrangements with the
issuer of the instrument. Such obligations are usually unrated by a rating
agency.     
 
  The Portfolio may purchase variable rate securities with remaining maturities
of one year or more issued by U.S. government agencies or instrumentalities or
guaranteed by the U.S. government. The Portfolio may also acquire certain
variable and floating rate instruments issued by U.S. companies. The yield of
these securities varies in relation to changes in specific money market rates
such as the prime rate. These changes
 
                                       4
<PAGE>
 
are reflected in adjustments to the yields of the variable rate securities at
least semi-annually, and different securities may have different adjustment
rates.
 
  ADJUSTABLE RATE AND FLOATING RATE MORTGAGE-BACKED SECURITIES. Certain
Portfolios may invest in adjustable rate mortgage ("ARM") and floating rate
mortgage-backed securities. Because the interest rates on ARM and floating rate
mortgage-backed securities are reset in response to changes in a specified
market index, the values of such securities tend to be less sensitive to
interest rate fluctuations than the values of fixed-rate securities. As a
result, during periods of rising interest rates, ARMs generally do not decrease
in value as much as fixed rate securities. Conversely, during periods of
declining interest rates, ARMs generally do not increase in value as much as
fixed rate securities. ARM mortgage-backed securities represent a right to
receive interest payments at a rate that is adjusted to reflect the interest
earned on a pool of ARMs. ARMs generally provide that the borrower's mortgage
interest rate may not be adjusted above a specified lifetime maximum rate or,
in some cases, below a minimum lifetime rate. In addition, certain ARMs provide
for limitations on the maximum amount by which the mortgage interest rate may
adjust for any single adjustment period. ARMs also may provide for limitations
on changes in the maximum amount by which the borrower's monthly payment may
adjust for any single adjustment period. In the event that a monthly payment is
not sufficient to pay the interest accruing on the ARM, any such excess
interest is added to the mortgage loan ("negative amortization"), which is
repaid through future monthly payments. If the monthly payment exceeds the sum
of the interest accrued at the applicable mortgage interest rate and the
principal payment that would have been necessary to amortize the outstanding
principal balance over the remaining term of the loan, the excess reduces the
principal balance of the ARM. Borrowers under ARMs experiencing negative
amortization may take longer to build up their equity in the underlying
property and may be more likely to default.
 
  The rates of interest payable on certain ARMs, and therefore on certain ARM
mortgage-backed securities, are based on indices, such as the one-year constant
maturity Treasury rate, that reflect changes in market interest rates. Others
are based on indices, such as the 11th District Federal Home Loan Bank Cost of
Funds index ("COFI"), that tend to lag behind changes in market interest rates.
The values of ARM mortgage-backed securities supported by ARMs that adjust
based on lagging indices tend to be somewhat more sensitive to interest rate
fluctuations than those reflecting current interest rate levels, although the
values of such ARM mortgage-backed securities still tend to be less sensitive
to interest rate fluctuations than fixed-rate securities.
 
  Floating rate mortgage-backed securities are classes of mortgage-backed
securities that have been structured to represent the right to receive interest
payments at rates that fluctuate in accordance with an index but that generally
are supported by pools comprised of fixed-rate mortgage loans. As with ARM
mortgage-backed securities, interest rate adjustments on Floating Rate
mortgage-backed securities may be based on indices that lag behind market
interest rates. Interest rates on floating rate mortgage-backed securities
generally are adjusted monthly. Floating rate mortgage-backed securities are
subject to lifetime interest rate caps, but they generally are not subject to
limitations on monthly or other periodic changes in interest rates or monthly
payments.
   
  SPECIAL CHARACTERISTICS OF MORTGAGE- AND ASSET-BACKED SECURITIES. Prepayments
on a pool of mortgage loans are influenced by a variety of economic,
geographic, social and other factors, including changes in mortgagors' housing
needs, job transfers, unemployment, mortgagors' net equity in the mortgaged
properties and servicing decisions. Generally, however, prepayments on fixed-
rate mortgage loans will increase during a period of falling interest rates and
decrease during a period of rising interest rates. Similar factors apply to
prepayments on asset-backed securities, but the receivables underlying asset-
backed securities generally are of a shorter maturity and thus are less likely
to experience substantial prepayments. Such securities, however, often provide
that for a specified time period the issuers will replace receivables in the
pool that are repaid with comparable obligations. If the issuer is unable to do
so, repayment of principal on the asset-backed securities may commence at an
earlier date. Mortgage- and asset-backed securities may decrease in value as a
    
                                       5
<PAGE>
 
result of increases in interest rates and may benefit less than other fixed-
income securities from declining interest rates because of the risk of
prepayment.
 
  ARMS also may be subject to a greater rate of prepayments in a declining
interest rate environment. For example, during a period of declining interest
rates, prepayments on ARMs could increase because the availability of fixed
mortgage loans at competitive interest rates may encourage mortgagors to "lock-
in" at a lower interest rate. Conversely, during a period of rising interest
rates, prepayments on ARMs might decrease. The rate of prepayments with respect
to ARMs has fluctuated in recent years.
 
  The rate of interest on mortgage-backed securities is lower than the interest
rates paid on the mortgages included in the underlying pool due to the annual
fees paid to the servicer of the mortgage pool for passing through monthly
payments to certificateholders and to any guarantor, and due to any yield
retained by the issuer. Actual yield to the holder may vary from the coupon
rate, even if adjustable, if the mortgage-backed securities are purchased or
traded in the secondary market at a premium or discount. In addition, there is
normally some delay between the time the issuer receives mortgage payments from
the servicer and the time the issuer makes the payments on the mortgage-backed
securities, and this delay reduces the effective yield to the holder of such
securities.
   
  ILLIQUID SECURITIES. Each Portfolio may invest up to 10% (15% for the
Strategic Fixed Income and Aggressive Growth Portfolios) of its net assets in
illiquid securities. The term "illiquid securities" for this purpose means
securities that cannot be disposed of within seven days in the ordinary course
of business at approximately the amount at which a Portfolio has valued the
securities and includes, among other things, purchased over-the-counter ("OTC")
options, repurchase agreements maturing in more than seven days and restricted
securities other than those securities Mitchell Hutchins or the applicable Sub-
Adviser has determined are liquid pursuant to guidelines established by the
Fund's board of trustees. The assets used as cover for OTC options written by a
Portfolio will be considered illiquid unless the OTC options are sold to
qualified dealers who agree that the Portfolio may repurchase any OTC option it
writes at a maximum price to be calculated by a formula set forth in the option
agreement. The cover for an OTC option written subject to this procedure will
be considered illiquid only to the extent that the maximum repurchase price
under the option formula exceeds the intrinsic value of the option. Illiquid
restricted securities may be sold only in privately negotiated transactions or
in public offerings with respect to which a registration statement is in effect
under the Securities Act of 1933 ("1933 Act"). Restricted securities acquired
by the Strategic Fixed Income, Global Income and Global Growth Portfolios
include those that are subject to restrictions contained in the securities laws
of other countries. For these Portfolios, securities that are freely marketable
in the country where they are principally traded, but would not be freely
marketable in the United States, will not be considered illiquid. Where
registration is required, a Portfolio may be obligated to pay all or part of
the registration expenses and a considerable period may elapse between the time
of the decision to sell and the time it may be permitted to sell a security
under an effective registration statement. If, during such a period, adverse
market conditions were to develop, the Portfolio might obtain a less favorable
price than prevailed when it decided to sell.     
 
  Not all restricted securities are illiquid. In recent years a large
institutional market has developed for certain securities that are not
registered under the 1933 Act, including private placements, repurchase
agreements, commercial paper, foreign securities and corporate bonds and notes.
These instruments are often restricted securities because the securities are
sold in transactions not requiring registration. Institutional investors
generally will not seek to sell these instruments to the general public, but
instead will often depend either on an efficient institutional market in which
such unregistered securities can be readily resold or on an issuer's ability to
honor a demand for repayment. Therefore, the fact that there are contractual or
legal restrictions on resale to the general public or certain institutions is
not dispositive of the liquidity of such investments.
 
  Rule 144A under the 1933 Act establishes a "safe harbor" from the
registration requirements of the 1933 Act for resales of certain securities to
qualified institutional buyers. Institutional markets for restricted
 
                                       6
<PAGE>
 
securities have developed as a result of Rule 144A, providing both readily
ascertainable values for restricted securities and the ability to liquidate an
investment to satisfy share redemption orders. Such markets might include
automated systems for the trading, clearance and settlement of unregistered
securities of domestic and foreign issuers, such as the PORTAL System sponsored
by the National Association of Securities Dealers, Inc. An insufficient number
of qualified buyers interested in purchasing Rule 144A-eligible restricted
securities held by a Portfolio, however, could affect adversely the
marketability of such portfolio securities and a Portfolio might be unable to
dispose of such securities promptly or at favorable prices.
 
  The board of trustees has delegated the function of making day-to-day
determinations of liquidity to Mitchell Hutchins or the applicable Sub-Adviser,
pursuant to guidelines approved by the board. Mitchell Hutchins or the
applicable Sub-Adviser takes into account a number of factors in reaching
liquidity decisions, including but not limited to (1) the frequency of trades
for the security, (2) the number of dealers that make quotes for the security,
(3) the number of dealers that have undertaken to make a market in the
security, (4) the number of other potential purchasers and (5) the nature of
the security and how trading is effected (e.g., the time needed to sell the
security, how bids are solicited and the mechanics of transfer). Mitchell
Hutchins or the applicable Sub-Adviser monitors the liquidity of restricted
securities in each Portfolio and reports periodically on such decisions to the
board of trustees.
   
  SECTION 4(2) PAPER. Commercial paper issues in which the Portfolios may
invest include securities issued by major corporations without registration
under the 1933 Act in reliance on the exemption from such registration afforded
by Section 3(a)(3) thereof, and commercial paper issued in reliance on the so-
called "private placement" exemption from registration which is afforded by
Section 4(2) of the 1933 Act ("Section 4(2) paper"). Section 4(2) paper is
restricted as to disposition under the federal securities laws in that any
resale must similarly be made in an exempt transaction. Section 4(2) paper is
normally resold to other institutional investors through or with the assistance
of investment dealers who make a market in Section 4(2) paper, thus providing
liquidity. Section 4(2) paper that is issued by a company that files reports
under the Securities Exchange Act of 1934 is generally eligible to be sold in
reliance on the safe harbor of Rule 144A described under "Illiquid Securities"
above. The Portfolios' 10% (15% for the Strategic Fixed Income and Aggressive
Growth Portfolios) limitation on investments in illiquid securities includes
Section 4(2) paper other than Section 4(2) paper that Mitchell Hutchins or the
applicable Sub-Adviser has determined to be liquid pursuant to guidelines
established by the Fund's board of trustees. The board has delegated to
Mitchell Hutchins or the applicable Sub-Adviser the function of making day-to-
day determinations of liquidity with respect to Section 4(2) paper, pursuant to
guidelines approved by the board that require Mitchell Hutchins or the
applicable Sub-Adviser to take into account the same factors described under
"Illiquid Securities" above for other restricted securities and require
Mitchell Hutchins or the applicable Sub-Adviser to perform the same monitoring
and reporting functions.     
 
  REPURCHASE AGREEMENTS. Repurchase agreements are transactions in which a
Portfolio purchases securities from a bank or recognized securities dealer and
simultaneously commits to resell the securities to the bank or dealer at an
agreed-upon date and price reflecting a market rate of interest unrelated to
the coupon rate or maturity of the purchased securities. The Portfolio
maintains custody of the underlying securities prior to their repurchase; thus,
the obligation of the bank or dealer to pay the repurchase price on the date
agreed to is, in effect, secured by such securities. If the value of these
securities is less than the repurchase price, plus any agreed-upon additional
amount, the other party to the agreement must provide additional collateral so
that at all times the collateral is at least equal to the repurchase price plus
any agreed-upon additional amount. The difference between the total amount to
be received upon repurchase of the securities and the price that was paid by
the Portfolio upon their acquisition is accrued as interest and included in the
Portfolio's net investment income.
 
  Repurchase agreements carry certain risks not associated with direct
investments in securities, including possible declines in the market value of
the underlying securities and delays and costs to a Portfolio if the other
party to a repurchase agreement becomes insolvent. Each Portfolio intends to
enter into repurchase
 
                                       7
<PAGE>
 
agreements only with banks and dealers in transactions believed by Mitchell
Hutchins or the applicable Sub-Adviser to present minimum credit risks in
accordance with guidelines established by the Fund's board of trustees.
Mitchell Hutchins or the applicable Sub-Adviser will review and monitor the
creditworthiness of those institutions under the board's general supervision.
   
  REVERSE REPURCHASE AGREEMENTS. Each Portfolio may enter into reverse
repurchase agreements with banks and securities dealers up to an aggregate
value of not more than 5% (33 1/3% for the Strategic Fixed Income Portfolio and
10% for the Global Income Portfolio) of its total assets. Such agreements
involve the sale of securities held by the Portfolio subject to the Portfolio's
agreement to repurchase the securities at an agreed-upon date and price
reflecting a market rate of interest. Such agreements are considered to be
borrowings and may be entered into by Portfolios other than the Strategic Fixed
Income Portfolio only for temporary purposes. While a reverse repurchase
agreement is outstanding, a Portfolio's custodian segregates assets to cover
the amount of the Portfolio's obligations under the reverse repurchase
agreement. See "Investment Policies and Limitations--Segregated Accounts." No
Portfolio other than the Strategic Fixed Income Portfolio will purchase
securities while borrowings (including reverse repurchase agreements) in excess
of 5% of its total assets are outstanding. No Portfolio other than the
Strategic Fixed Income and Global Income Portfolios has any intention of
entering into reverse repurchase agreements during the coming year.     
 
  WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. A security purchased on a when-
issued or delayed delivery basis is recorded as an asset on the commitment date
and is subject to changes in market value, generally based upon changes in the
level of interest rates. Thus, fluctuation in the value of the security from
the time of the commitment date will affect the Fund's net asset value. When a
Portfolio commits to purchase securities on a when-issued or delayed delivery
basis, its custodian segregates assets to cover the amount of the commitment.
See "Investment Policies and Limitations--Segregated Accounts." The Portfolios
purchase when-issued securities only with the intention of taking delivery, but
may sell the right to acquire the security prior to delivery if Mitchell
Hutchins or the applicable Sub-Adviser deems it advantageous to do so, which
may result in a capital gain or loss to a Portfolio.
   
  LENDING OF PORTFOLIO SECURITIES. As indicated in the Prospectus, the
Portfolios other than the Money Market Portfolio are authorized to lend their
portfolio securities. The Money Market Portfolio is authorized to lend up to
10% of the total value of its portfolio securities but has no intention of
doing so during the coming year. A Portfolio may lend its portfolio securities
to broker-dealers or institutional investors that Mitchell Hutchins or the
applicable Sub-Adviser deems qualified, but only when the borrower maintains
with the Portfolio's custodian bank collateral either in cash or money market
instruments, marked to market daily, in an amount at least equal to the market
value of the securities loaned, plus accrued interest and dividends. In
determining whether to lend securities to a particular broker-dealer or
institutional investor, Mitchell Hutchins or the applicable Sub-Adviser will
consider, and during the period of the loan will monitor, all relevant facts
and circumstances, including the creditworthiness of the borrower. The
Portfolios will retain authority to terminate any loans at any time. A
Portfolio may pay reasonable administrative and custodial fees in connection
with a loan and may pay a negotiated portion of the interest earned on the cash
or money market instruments held as collateral to the borrower or placing
broker. A Portfolio will receive reasonable interest on the loan or a flat fee
from the borrower and amounts equivalent to any dividends, interest or other
distributions on the securities loaned. A Portfolio will regain record
ownership of loaned securities to exercise beneficial rights, such as voting
and subscription rights and rights to dividends, interest or other
distributions, when regaining such rights is considered to be in the
Portfolio's interest.     
 
  SEGREGATED ACCOUNTS. When a Portfolio enters into certain transactions that
involve obligations to make future payments to third parties, including dollar
rolls, reverse repurchase agreements or the purchase of securities on a when-
issued or delayed delivery basis, the Portfolio will maintain with an approved
custodian in a segregated account cash, U.S. government securities or other
liquid high grade debt securities, marked to market daily, in an amount at
least equal to the Portfolio's obligation or commitment under such
transactions. As described below under "Hedging and Related Income Strategies,"
segregated accounts may
 
                                       8
<PAGE>
 
also be required in connection with certain transactions involving options or
futures contracts, interest rate protection transactions or forward currency
contracts.
 
  CONCENTRATION. All Portfolios follow a policy not to make an investment in
any one industry if the investment would cause the aggregate value of the
Portfolio's investment in such industry to exceed 25% of the Portfolio's total
assets, except that this policy does not apply to obligations issued or
guaranteed by the U.S. government, its agencies or instrumentalities ("U.S.
government securities"), certificates of deposit and bankers' acceptances. This
is a fundamental policy and cannot be changed with respect to a Portfolio
without the affirmative vote of its shareholders. Under this policy as applied
to the Money Market Portfolio, gas, electric, water and telephone companies are
considered separate industries and, with respect to finance companies, the
following categories are considered separate industries: (a) captive automotive
finance; (b) captive equipment finance; (c) retail finance; (d) consumer loan;
and (e) diversified finance.
 
  INVESTMENT LIMITATIONS. Except as indicated otherwise, each Portfolio may
not:
 
    (1) purchase securities (except U.S. government securities) of any one
  issuer, if as a result at the time of purchase more than 5% of the
  Portfolio's total assets would be invested in such issuer, or the Portfolio
  would own or hold 10% or more of the outstanding voting securities of that
  issuer, except that 25% of the total assets of the Portfolio (50% in the
  case of the Global Income Portfolio) may be invested without regard to this
  limitation;
 
    (2) purchase securities on margin, except for short-term credit necessary
  for clearance of portfolio transactions and except that a Portfolio that
  may use options or futures strategies may make margin deposits in
  connection with its use of options, futures contracts and options on
  futures contracts;
 
    (3) mortgage, pledge, hypothecate or in any manner transfer, as security
  for indebtedness, any securities owned or held by the Portfolio, except as
  may be necessary in connection with permitted borrowings and then not in
  excess of 5% of the Portfolio's total assets taken at cost, provided that
  this does not prohibit escrow, collateral or margin arrangements in
  connection with the use of options, futures contracts and options on
  futures contracts by a Portfolio that may use options or futures
  strategies;
     
    (4) make short sales of securities or maintain a short position, except
  that a Portfolio that may use options or futures strategies may make short
  sales and may maintain short positions in connection with its use of
  options, futures contracts and options on futures contracts and the High
  Grade Fixed Income, Growth and Income and Aggressive Growth Portfolios may
  sell short "against the box";     
 
    (5) purchase or sell real estate, provided that a Portfolio may invest in
  securities secured by real estate or interests therein or issued by
  companies which invest in real estate or interests therein;
     
    (6) purchase or sell commodities or commodity contracts, except that a
  Portfolio that may use options or futures strategies may purchase or sell
  stock index futures and interest rate futures and options thereon and the
  Strategic Fixed Income, Global Income and Global Growth Portfolios may
  purchase or sell foreign currency futures and options thereon;     
 
    (7) invest in oil, gas or mineral-related programs or leases;
     
    (8) make loans, except through loans of portfolio securities of up to 10%
  of the value of the Portfolio's securities (33 1/3% for the Strategic Fixed
  Income Portfolio) and through repurchase agreements, provided that for
  purposes of this restriction the acquisition of bonds, debentures or other
  corporate debt securities and investment in government obligations, short-
  term commercial paper, certificates of deposit and bankers' acceptances
  shall not be deemed to be the making of a loan;     
 
    (9) purchase any securities issued by any other investment company except
  by purchase in the open market where no commission or profit, other than a
  customary broker's commission, is earned by any sponsor or dealer
  associated with the investment company whose shares are acquired as a
  result of such purchase, provided that such securities in the aggregate do
  not represent more than 10% of the total assets of the Portfolio, and
  except in connection with the merger, consolidation or acquisition of all
  the securities or assets of another investment company; or
 
                                       9
<PAGE>
 
     
    (10) (for Portfolios other than Strategic Fixed Income Portfolio) issue
  senior securities or borrow money, except from banks for temporary purposes
  and except for reverse repurchase agreements and provided that the
  aggregate amount of all such borrowing does not exceed 10% (33 1/3% for the
  High Grade Fixed Income Portfolio and 20% for the Aggressive Growth
  Portfolio) of the total asset value of the Portfolio at the time of such
  borrowing; provided further that the Portfolio will not purchase securities
  while borrowings (including reverse repurchase agreements) in excess of 5%
  of the total asset value of the Portfolio are outstanding.     
     
    (11) Strategic Fixed Income Portfolio may not issue senior securities or
  borrow money, except from banks or through reverse repurchase agreements
  and dollar rolls, and then in an aggregate amount not in excess of 33 1/3%
  of the Portfolio's total assets (including the amount of the borrowing but
  reduced by any liabilities not constituting senior securities) at the time
  of such borrowings; except that the Portfolio may borrow up to an
  additional 5% of its total assets (not including the amount borrowed) for
  temporary or emergency purposes.     
 
  The foregoing fundamental investment limitations cannot be changed with
respect to a Portfolio without the affirmative vote of the lesser of (a) more
than 50% of the outstanding shares of the Portfolio or (b) 67% or more of the
Portfolio's shares present at a meeting of its shareholders if more than 50% of
the outstanding shares of the Portfolio are represented at the meeting in
person or by proxy. If a percentage restriction is adhered to at the time of an
investment or transaction, a later change in percentage resulting from a change
in values of portfolio securities or amount of total assets will not be
considered a violation of any of the foregoing limitations.
 
  The following investment restrictions may be changed by the vote of the
Fund's board of trustees without shareholder approval:
 
    (1) No Portfolio will hold assets of any issuers, at the end of any
  calendar quarter (or within 30 days thereafter), to the extent such
  holdings would cause the Portfolio to fail to comply with the
  diversification requirements imposed by section 817(h) of the Internal
  Revenue Code and the Treasury regulations issued thereunder on segregated
  asset accounts used to fund variable annuity contracts; and
 
    (2) Except under unusual circumstances, the Global Growth Portfolio will
  not purchase securities issued by investment companies unless they are
  issued by companies that follow a policy of investment primarily in the
  capital markets of a single foreign country.
 
                     HEDGING AND RELATED INCOME STRATEGIES
   
  As discussed in the Prospectus, Mitchell Hutchins or the applicable Sub-
Adviser may use a variety of financial instruments ("Hedging Instruments"),
including certain options, futures contracts (sometimes referred to as
"futures") and options on futures contracts, to attempt to hedge the
Portfolios' investments or attempt to enhance the Portfolios' income. For the
Strategic Fixed Income, Global Income and Global Growth Portfolios, Mitchell
Hutchins or the applicable Sub-Adviser also may use forward currency contracts,
foreign currency options and futures and options thereon. Strategic Fixed
Income and Global Income Portfolios also may enter into interest rate
protection transactions. The particular Hedging Instruments are described in
Appendix B to the Prospectus. The Money Market and Asset Allocation Portfolios
are not authorized to engage in hedging or related income strategies.     
 
  Hedging strategies can be broadly categorized as "short hedges" and "long
hedges." A short hedge is a purchase or sale of a Hedging Instrument intended
partially or fully to offset potential declines in the value of one or more
investments held by a Portfolio. Thus, in a short hedge a Portfolio takes a
position in a Hedging Instrument whose price is expected to move in the
opposite direction of the price of the investment being hedged. For example, a
Portfolio might purchase a put option on a security to hedge against a
potential decline in the value of that security. If the price of the security
declined below the exercise price of the put, the Portfolio could exercise the
put and thus limit its loss below the exercise price to the premium paid plus
 
                                       10
<PAGE>
 
transaction costs. In the alternative, because the value of the put option can
be expected to increase as the value of the underlying security declines, the
Portfolio might be able to close out the put option and realize a gain to
offset the decline in the value of the security.
 
  Conversely, a long hedge is a purchase or sale of a Hedging Instrument
intended partially or fully to offset potential increases in the acquisition
cost of one or more investments that a Portfolio intends to acquire. Thus, in a
long hedge a Portfolio takes a position in a Hedging Instrument whose price is
expected to move in the same direction as the price of the prospective
investment being hedged. For example, a Portfolio might purchase a call option
on a security it intends to purchase in order to hedge against an increase in
the cost of the security. If the price of the security increased above the
exercise price of the call, the Portfolio could exercise the call and thus
limit its acquisition cost to the exercise price plus the premium paid and
transaction costs. Alternatively, the Portfolio might be able to offset the
price increase by closing out an appreciated call option and realizing a gain.
 
  A Portfolio may purchase and write (sell) covered straddles on securities and
stock indices. A long straddle is a combination of a call and a put option
purchased on the same security or on the same futures contract, where the
exercise price of the put is less than or equal to the exercise price of the
call. A Portfolio might enter into a long straddle when Mitchell Hutchins or
the applicable Sub-Adviser believes it likely that interest rates will be more
volatile during the term of the option than the option pricing implies. A short
straddle is a combination of a call and a put written on the same security
where the exercise price of the put is less than or equal to the exercise price
of the call. A Portfolio might enter into a short straddle when Mitchell
Hutchins or the applicable Sub-Adviser believes it unlikely that interest rates
will be as volatile during the term of the option as the option pricing
implies.
 
  Hedging Instruments on securities generally are used to hedge against price
movements in one or more particular securities positions that a Portfolio owns
or intends to acquire. Hedging Instruments on stock indices, in contrast,
generally are used to hedge against price movements in broad equity market
sectors in which the Portfolio has invested or expects to invest. Hedging
Instruments on debt securities may be used to hedge either individual
securities or broad fixed income market sectors.
 
  The use of Hedging Instruments is subject to applicable regulations of the
SEC, the several options and futures exchanges upon which they are traded, the
Commodity Futures Trading Commission ("CFTC") and various state regulatory
authorities. In addition, a Portfolio's ability to use Hedging Instruments will
be limited by tax considerations. See "Taxes."
 
  In addition to the products, strategies and risks described below and in the
Prospectus, Mitchell Hutchins or the applicable Sub-Adviser expects to discover
additional opportunities in connection with options, future contracts, forward
currency contracts and other hedging techniques. These new opportunities may
become available as Mitchell Hutchins or the applicable Sub-Adviser develops
new techniques, as regulatory authorities broaden the range of permitted
transactions and as new options, futures contracts, forward currency contracts
or other techniques are developed. Mitchell Hutchins or the applicable Sub-
Adviser may utilize these opportunities to the extent that they are consistent
with the Portfolios' investment objectives and permitted by the Portfolios'
investment limitations and applicable regulatory authorities. The Fund's
Prospectus or Statement of Additional Information will be supplemented to the
extent that new products or techniques involve materially different risks than
those described below or in the Prospectus.
 
  SPECIAL RISKS OF HEDGING STRATEGIES. The use of Hedging Instruments involves
special considerations and risks, as described below. Risks pertaining to
particular Hedging Instruments are described in the sections that follow.
 
    (1) Successful use of most Hedging Instruments depends upon Mitchell
  Hutchins' or the applicable Sub-Adviser's ability to predict movements of
  the overall securities, currency and interest rate markets, which requires
  different skills than predicting changes in the prices of individual
  securities. While
 
                                       11
<PAGE>
 
  Mitchell Hutchins or the applicable Sub-Adviser is experienced in the use
  of Hedging Instruments, there can be no assurance that any particular
  hedging strategy adopted will succeed.
 
    (2) There might be imperfect correlation, or even no correlation, between
  price movements of a Hedging Instrument and price movements of the
  investments being hedged. For example, if the value of a Hedging Instrument
  used in a short hedge increased by less than the decline in value of the
  hedged investment, the hedge would not be fully successful. Such a lack of
  correlation might occur due to factors unrelated to the value of the
  investments being hedged, such as speculative or other pressures on the
  markets in which Hedging Instruments are traded. The effectiveness of
  hedges using Hedging Instruments or indices will depend on the degree of
  correlation between price movements in the index and price movements in the
  securities being hedged.
 
    (3) Hedging strategies, if successful, can reduce risk of loss by wholly
  or partially offsetting the negative effect of unfavorable price movements
  in the investments being hedged. However, hedging strategies can also
  reduce opportunity for gain by offsetting the positive effect of favorable
  price movements in the hedged investments. For example, if a Portfolio
  entered into a short hedge because Mitchell Hutchins or the applicable Sub-
  Adviser projected a decline in the price of a security held by a Portfolio,
  and the price of that security increased instead, the gain from that
  increase might be wholly or partially offset by a decline in the price of
  the Hedging Instrument. Moreover, if the price of the Hedging Instrument
  declined by more than the increase in the price of the security, the
  Portfolio could suffer a loss. In either such case, the Portfolio would
  have been in a better position had it not hedged at all.
 
    (4) As described below, a Portfolio might be required to maintain assets
  as "cover," maintain segregated accounts or make margin payments when it
  takes positions in Hedging Instruments involving obligations to third
  parties (i.e., Hedging Instruments other than purchased options). If a
  Portfolio were unable to close out its positions in such Hedging
  Instruments, it might be required to continue to maintain such assets or
  accounts or make such payments until the position expired or matured. These
  requirements might impair a Portfolio's ability to sell a portfolio
  security or make an investment at a time when it would otherwise be
  favorable to do so, or require that a Portfolio sell a portfolio security
  at a disadvantageous time. A Portfolio's ability to close out a position in
  a Hedging Instrument prior to expiration or maturity depends on the
  existence of a liquid secondary market or, in the absence of such a market,
  the ability and willingness of a contra party to enter into a transaction
  closing out the position. Therefore, there is no assurance that any hedging
  position can be closed out at a time and price that is favorable to the
  Portfolio.
 
  COVER FOR HEDGING STRATEGIES. Transactions using Hedging Instruments, other
than purchased options, expose a Portfolio to an obligation to another party. A
Portfolio will not enter into any such transactions unless it owns either (1)
an offsetting ("covered") position in securities, currencies or other options,
futures contracts or forward currency contracts or (2) cash and short-term
liquid debt securities, with a value sufficient at all times to cover its
potential obligations to the extent not covered as provided in (1) above. Each
Portfolio will comply with SEC guidelines regarding cover for hedging
transactions and will, if the guidelines so require, set aside cash, U.S.
government securities or other liquid, high-grade debt securities in a
segregated account with its custodian in the prescribed amount.
 
  Assets used as cover or held in a segregated account cannot be sold while the
position in the corresponding Hedging Instrument is open, unless they are
replaced with similar assets. As a result, the commitment of a large portion of
a Portfolio's assets to cover or segregated accounts could impede portfolio
management or the Portfolio's ability to meet redemption requests or other
current obligations.
   
  OPTIONS. Each Portfolio that may use options may purchase put and call
options, and write (sell) covered put and call options, on equity and debt
securities and, in the case of Strategic Fixed Income, Global Income and Global
Growth Portfolios, on foreign currencies. Each Portfolio that may use options
may purchase put and call options and write (sell) covered call options on
stock indices. The purchase of call     
 
                                       12
<PAGE>
 
options serves as a long hedge, and the purchase of put options serves as a
short hedge. Writing covered put or call options can enable a Portfolio to
enhance income by reason of the premiums paid by the purchasers of such
options. Writing covered put options serves as a limited long hedge because
increases in the value of the hedged instrument would be offset to the extent
of the premium received for writing the option. However, if the market price of
the security underlying a covered put option declines to less than the exercise
price of the option, minus the premium received, the Portfolio would expect to
suffer a loss. Writing covered call options serves as a limited short hedge,
because declines in the value of the hedged investment would be offset to the
extent of the premium received for writing the option. However, if the security
appreciates to a price higher than the exercise price of the call option, it
can be expected that the option will be exercised and the Portfolio will be
obligated to sell the security at less than its market value. The securities or
other assets used as cover for OTC options written by a Portfolio would be
considered illiquid to the extent described under "Investment Policies and
Restrictions--Illiquid Securities."
 
  The value of an option position will reflect, among other things, the current
market value of the underlying investment, the time remaining until expiration,
the relationship of the exercise price to the market price of the underlying
investment, the historical price volatility of the underlying investment and
general market conditions. Options normally have expiration dates of up to nine
months. Options that expire unexercised have no value.
 
  A Portfolio may effectively terminate its right or obligation under an option
by entering into a closing transaction. For example, a Portfolio may terminate
its obligation under a call option that it had written by purchasing an
identical call option; this is known as a closing purchase transaction.
Conversely, a Portfolio may terminate a position in a put or call option it had
purchased by writing an identical put or call option; this is known as a
closing sale transaction.
 
  The Portfolios may purchase or write both exchange-traded and OTC options.
Currently, many options on equity securities are exchange-traded. Exchange
markets for options on debt securities and foreign currencies exist but are
relatively new, and these instruments are primarily traded on the OTC market.
Exchange-traded options in the United States are issued by a clearing
organization affiliated with the exchange on which the option is listed which,
in effect, guarantees completion of every exchange-traded option transaction.
In contrast, OTC options are contracts between the Portfolio and its contra
party (usually a securities dealer or a bank) with no clearing organization
guarantee. Thus, when the Portfolio purchases or writes an OTC option, it
relies on the contra party to make or take delivery of the underlying
investment upon exercise of the option. Failure by the contra party to do so
would result in the loss of any premium paid by the Portfolio as well as the
loss of any expected benefits of the transaction. A Portfolio will enter into
OTC option transactions only with contra parties that have a net worth of at
least $20 million.
 
  Generally, the OTC debt and foreign currency options used by the Portfolios
are European-style options. This means that the option is only exercisable
immediately prior to its expiration. This is in contrast to American-style
options, which are exercisable at any time prior to the expiration date of the
option.
 
  A Portfolio's ability to establish and close out positions in exchange-listed
options depends on the existence of a liquid market. Each Portfolio intends to
purchase or write only those exchange-traded options for which there appears to
be a liquid secondary market. However, there can be no assurance that such a
market will exist at any particular time. Closing transactions can be made for
OTC options only by negotiating directly with the contra party, or by a
transaction in the secondary market if any such market exists. Although a
Portfolio will enter into OTC options only with contra parties that are
expected to be capable of entering into closing transactions with the
Portfolio, there is no assurance that the Portfolio will in fact be able to
close out an OTC option position at a favorable price prior to expiration. In
the event of insolvency of the contra party, the Portfolio might be unable to
close out an OTC option position at any time prior to its expiration.
 
                                       13
<PAGE>
 
  If the Portfolio were unable to effect a closing transaction for an option it
had purchased, it would have to exercise the option to realize any profit. The
inability to enter into a closing purchase transaction for a covered call
option written by a Portfolio could cause material losses because the Portfolio
would be unable to sell the investment used as cover for the written option
until the option expires or is exercised.
 
  LIMITATIONS ON THE USE OF OPTIONS. The Portfolios' use of options is governed
by the following guidelines, which can be changed by the Fund's board of
trustees without shareholder vote:
 
    (1) A Portfolio may purchase a put or call option, including any
  straddles or spreads, only if the value of its premium, when aggregated
  with the premiums on all other options held by the Portfolio, does not
  exceed 5% of the Portfolio's total assets.
 
    (2) The aggregate value of securities underlying put options written by a
  Portfolio, determined as of the date the put options are written, will not
  exceed 50% of the Portfolio's net assets.
 
    (3) The aggregate premiums paid on all options (including options on
  securities, foreign currencies and stock or bond indices and options on
  futures contracts) purchased by a Portfolio that are held at any time will
  not exceed 20% of the Portfolio's net assets.
 
  FUTURES. The purchase of futures or call options thereon can serve as a long
hedge, and the sale of futures or the purchase of put options thereon can serve
as a short hedge. Writing covered call options on futures contracts can serve
as a limited short hedge, using a strategy similar to that used for writing
covered call options on securities and indices.
 
  Futures strategies also can be used to manage the average duration of a
Portfolio. If Mitchell Hutchins or the applicable Sub-Adviser wishes to shorten
the average duration of a Portfolio, the Portfolio may sell a futures contract
or a call option thereon, or purchase a put option on that futures contract. If
Mitchell Hutchins or the applicable Sub-Adviser wishes to lengthen the average
duration of a Portfolio, the Portfolio may buy a futures contract or a call
option thereon.
   
  The Strategic Fixed Income, Global Income and Global Growth Portfolios may
also write put options on foreign currency futures contracts while at the same
time purchasing call options on the same futures contracts in order
synthetically to create a long futures contract position. Such options would
have the same strike prices and expiration dates. Each Portfolio will engage in
this strategy only when it is more advantageous to the Portfolio than is
purchasing the futures contract.     
 
  No price is paid upon entering into a futures contract. Instead, at the
inception of a futures contract a Portfolio is required to deposit in a
segregated account with its custodian, in the name of the futures broker
through whom the transaction was effected, "initial margin" consisting of cash,
U.S. government securities or other liquid, high-grade debt securities, in an
amount generally equal to 10% or less of the contract value. Margin must also
be deposited when writing an option on a futures contract, in accordance with
applicable exchange rules. Unlike margin in securities transactions, initial
margin on futures contracts does not represent a borrowing, but rather is in
the nature of a performance bond or good-faith deposit that is returned to the
Portfolio at the termination of the transaction if all contractual obligations
have been satisfied. Under certain circumstances, such as periods of high
volatility, the Portfolio may be required by an exchange to increase the level
of its initial margin payment, and initial margin requirements might be
increased generally in the future by regulatory action.
 
  Subsequent "variation margin" payments are made to and from the futures
broker daily as the value of the futures position varies, a process known as
"marking to market." Variation margin does not involve borrowing, but rather
represents a daily settlement of the Portfolio's obligations to or from a
futures broker. When a Portfolio purchases an option on a future, the premium
paid plus transaction costs is all that is at risk. In contrast, when a
Portfolio purchases or sells a futures contract or writes a call option
thereon, it is subject to daily variation margin calls that could be
substantial in the event of adverse price movements. If
 
                                       14
<PAGE>
 
the Portfolio has insufficient cash to meet daily variation margin
requirements, it might need to sell securities at a time when such sales are
disadvantageous.
 
  Holders and writers of futures positions and options on futures can enter
into offsetting closing transactions, similar to closing transactions on
options, by selling or purchasing, respectively, an instrument identical to the
instrument held or written. Positions in futures and options on futures may be
closed only on an exchange or board of trade that provides a secondary market.
Each Portfolio intends to enter into futures transactions only on exchanges or
boards of trade where there appears to be a liquid secondary market. However,
there can be no assurance that such a market will exist for a particular
contract at a particular time.
 
  Under certain circumstances, futures exchanges may establish daily limits on
the amount that the price of a future or related option can vary from the
previous day's settlement price; once that limit is reached, no trades may be
made that day at a price beyond the limit. Daily price limits do not limit
potential losses because prices could move to the daily limit for several
consecutive days with little or no trading, thereby preventing liquidation of
unfavorable positions.
 
  If a Portfolio were unable to liquidate a futures or related options position
due to the absence of a liquid secondary market or the imposition of price
limits, it could incur substantial losses. The Portfolio would continue to be
subject to market risk with respect to the position. In addition, except in the
case of purchased options, the Portfolio would continue to be required to make
daily variation margin payments and might be required to maintain the position
being hedged by the future or option or to maintain cash or securities in a
segregated account.
 
  Certain characteristics of the futures market might increase the risk that
movements in the prices of futures contracts or related options might not
correlate perfectly with movements in the prices of the investments being
hedged. For example, all participants in the futures and related options
markets are subject to daily variation margin calls and might be compelled to
liquidate futures or related options positions whose prices are moving
unfavorably to avoid being subject to further calls. These liquidations could
increase price volatility of the instruments and distort the normal price
relationship between the futures or options and the investments being hedged.
Also, because initial margin deposit requirements in the futures market are
less onerous than margin requirements in the securities markets, there might be
increased participation by speculators in the futures markets. This
participation also might cause temporary price distortions. In addition,
activities of large traders in both the futures and securities markets
involving arbitrage, "program trading" and other investment strategies might
result in temporary price distortions.
 
  LIMITATIONS ON THE USE OF FUTURES. The Portfolios' use of futures is governed
by the following guidelines, which can be changed by the Fund's board of
trustees without shareholder vote.
 
    (1) To the extent a Portfolio enters into futures contracts, options on
  futures positions and options on foreign currencies trade on a commodities
  exchange that are not for bona fide hedging purposes (as defined by the
  CFTC), the aggregate initial margin and premiums on those positions
  (excluding the amount by which options are "in-the-money") may not exceed
  5% of the Portfolio's net assets.
 
    (2) The aggregate premiums on all options (including options on
  securities, foreign currencies and stock indices and options on futures
  contracts) purchased by a Portfolio that are held at any time will not
  exceed 20% of the Portfolio's net assets.
 
    (3) The aggregate margin deposits on all futures contracts and options
  thereon held at any time by a Portfolio will not exceed 5% of the
  Portfolio's total assets.
   
  FOREIGN CURRENCY HEDGING STRATEGIES--SPECIAL CONSIDERATIONS. The Strategic
Fixed Income, Global Income and Global Growth Portfolios may use options and
futures on foreign currencies, as described above, and forward currency forward
contracts, as described below, to hedge against movements in the values of the
foreign currencies in which the Portfolios' securities are denominated. Such
currency hedges can protect     
 
                                       15
<PAGE>
 
against price movements in a security that a Portfolio owns or intends to
acquire that are attributable to changes in the value of the currency in which
it is denominated. Such hedges do not, however, protect against price movements
in the securities that are attributable to other causes.
 
  The Portfolios might seek to hedge against changes in the value of a
particular currency when no Hedging Instruments on that currency are available
or such Hedging Instruments are more expensive than certain other Hedging
Instruments. In such cases, a Portfolio may hedge against price movements in
that currency by entering into transactions using Hedging Instruments on
another foreign currency or a basket of currencies, the values of which
Mitchell Hutchins or the applicable Sub-Adviser believes will have a high
degree of positive correlation to the value of the currency being hedged. The
risk that movements in the price of the Hedging Instrument will not correlate
perfectly with movements in the price of the currency being hedged is magnified
when this strategy is used.
 
  The value of Hedging Instruments on foreign currencies depends on the value
of the underlying currency relative to the U.S. dollar. Because foreign
currency transactions occurring in the interbank market might involve
substantially larger amounts than those involved in the use of such Hedging
Instruments, the Portfolios could be disadvantaged by having to deal in the 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 generally is representative of very large transactions in the
interbank market and thus might not reflect odd-lot transactions where rates
might be less favorable. The interbank market in foreign currencies is a
global, round-the-clock market. To the extent the U.S. options or futures
markets are closed while the markets for the underlying currencies remain open,
significant price and rate movements might take place in the underlying markets
that cannot be reflected in the markets for the Hedging Instruments until they
reopen.
 
  Settlement of hedging transactions involving foreign currencies might be
required to take place within the country issuing the underlying currency.
Thus, a Portfolio might be required to accept or make delivery of the
underlying foreign currency in accordance with any U.S. or foreign regulations
regarding the maintenance of foreign banking arrangements by U.S. residents and
might be required to pay any fees, taxes and charges associated with such
delivery assessed in the issuing country.
   
  FORWARD CURRENCY CONTRACTS. The Strategic Fixed Income, Global Income and
Global Growth Portfolios may enter into forward currency contracts to purchase
or sell foreign currencies for a fixed amount of U.S. dollars or another
foreign currency. Such transactions may serve as long hedges--for example, a
Portfolio may purchase a forward currency contract to lock in the U.S. dollar
price of a security denominated in a foreign currency that the Portfolio
intends to acquire. Forward currency contract transactions may also serve as
short hedges--for example, a Portfolio may sell a forward currency contract to
lock in the U.S. dollar equivalent of the proceeds from the anticipated sale of
a security denominated in a foreign currency.     
 
  As noted above, these Portfolios may seek to hedge against changes in the
value of a particular currency by using forward contracts on another foreign
currency or a basket of currencies, the value of which Mitchell Hutchins or the
applicable Sub-Adviser believes will have a positive correlation to the values
of the currency being hedged. In addition, the Portfolios may use forward
currency contracts to shift exposure to foreign currency fluctuations from one
country to another. For example, if a Portfolio owns securities denominated in
a foreign currency and Mitchell Hutchins or the applicable Sub-Adviser believes
that currency will decline relative to another currency, it might enter into a
forward contract to sell an appropriate amount of the first foreign currency,
with payment to be made in the second foreign currency. Transactions that use
two foreign currencies are sometimes referred to as "cross hedging." Use of a
different foreign currency magnifies the
 
                                       16
<PAGE>
 
risk that movements in the price of the Hedging Instrument will not correlate
or will correlate unfavorably with the foreign currency being hedged.
 
  The cost to the Portfolios engaging in forward currency contracts varies with
factors such as the currency involved, the length of the contract period and
the market conditions then prevailing. Because forward currency contracts are
usually entered into on a principal basis, no fees or commissions are involved.
When a Portfolio enters into a forward currency contract, it relies on the
contra party to make or take delivery of the underlying currency at the
maturity of the contract. Failure by the contra party to do so would result in
the loss of any expected benefit of the transaction.
 
  As is the case with future contracts, holders and writers of forward currency
contracts can enter into offsetting closing transactions, similar to closing
transactions on futures, by selling or purchasing, respectively, an instrument
identical to the instrument held or written. Secondary markets generally do not
exist for forward currency contracts, with the result that closing transactions
generally can be made for forward currency contracts only by negotiating
directly with the contra party. Thus, there can be no assurance that a
Portfolio will in fact be able to close out a forward currency contract at a
favorable price prior to maturity. In addition, in the event of insolvency of
the contra party, the Portfolio might be unable to close out a forward currency
contract at any time prior to maturity. In either event, the Portfolio would
continue to be subject to market risk with respect to the position, and would
continue to be required to maintain a position in securities denominated in the
securities or currencies that are the subject of the hedge or to maintain cash
or securities in a segregated account.
 
  The precise matching of forward currency contract amounts and the value of
the securities involved generally will not be possible because the value of
such securities, measured in the foreign currency, will change after the
foreign currency contract has been established. Thus, a Portfolio might need to
purchase or sell foreign currencies in the spot (cash) market to the extent
such foreign currencies are not covered by forward contracts. The projection of
short-term currency market movements is extremely difficult, and the successful
execution of a short-term hedging strategy is highly uncertain.
   
  LIMITATIONS ON THE USE OF FORWARD CURRENCY CONTRACTS. The Strategic Fixed
Income, Global Income and Global Growth Portfolios may enter into forward
currency contracts or maintain a net exposure to such contracts only if (1) the
consummation of the contracts would not obligate the Portfolio to deliver an
amount of foreign currency in excess of the value of the position being hedged
by such contracts or (2) the Portfolio maintains appropriate assets in a
segregated account in an amount not less than the value of its total assets
committed to the consummation of the contract and not covered as provided in
(1) above, as described above in "Investment Policies and Limitations--
Segregated Accounts."     
   
  INTEREST RATE PROTECTION TRANSACTIONS. The Strategic Fixed Income and Global
Income Portfolios may enter into interest rate protection transactions,
including interest rate swaps and interest rate caps, collars and floors.
Interest rate swap transactions involve an agreement between two parties to
exchange payments that are based, for example, on variable and fixed rates of
interest and that are calculated on the basis of a specified amount of
principal (the "notional principal amount") for a specified period of time.
Interest rate cap and floor transactions involve an agreement between two
parties in which the first party agrees to make payments to the counterparty
when a designated market interest rate goes above (in the case of a cap) or
below (in the case of a floor) a designated level on predetermined dates or
during a specified time period. Interest rate collar transactions involve an
agreement between two parties in which payments are made when a designated
market interest rate either goes above a designated ceiling level or goes below
a designated floor level on predetermined dates or during a specified time
period.     
   
  The Strategic Fixed Income and Global Income Portfolios each expect to enter
into interest rate protection transactions to preserve a return or spread on a
particular investment or portion of its portfolio or to protect against any
increase in the price of securities it anticipates purchasing at a later date.
The Portfolios     
 
                                       17
<PAGE>
 
   
intend to use these transactions as a hedge and not as a speculative
investment. Interest rate protection transactions are subject to risks
comparable to those described above with respect to other hedging strategies.
       
  The Strategic Fixed Income and Global Income Portfolios each may enter into
interest rate swaps, caps, collars and floors on either an asset-based or
liability-based basis, depending on whether it is hedging its assets or its
liabilities, and will usually enter into interest rate swaps on a net basis,
i.e., the two payment streams are netted out, with the Portfolio receiving or
paying, as the case may be, only the net amount of the two payments. Inasmuch
as these interest rate protection transactions are entered into for good faith
hedging purposes, and inasmuch as segregated accounts will be established with
respect to such transactions, Mitchell Hutchins and the Portfolios believe such
obligations do not constitute senior securities and, accordingly, will not
treat them as being subject to the Portfolio's borrowing restrictions. The net
amount of the excess, if any, of a Portfolio's obligations over its
entitlements with respect to each interest rate swap will be accrued on a daily
basis and appropriate Portfolio assets having an aggregate net asset value at
least equal to the accrued excess will be maintained in a segregated account as
described above in "Investment Policies and Restrictions--Segregated Accounts."
Each Portfolio also will establish and maintain such segregated accounts with
respect to its total obligations under any interest rate swaps that are not
entered into on a net basis and with respect to any interest rate caps, collars
and floors that are written by the Portfolio.     
   
  The Strategic Fixed Income and Global Income Portfolios each will enter into
interest rate protection transactions only with banks and recognized securities
dealers believed by Mitchell Hutchins to present minimal credit risks in
accordance with guidelines established by the Fund's board of trustees. If
there is a default by the other party to such a transaction, the Portfolio will
have to rely on its contractual remedies (which may be limited by bankruptcy,
insolvency or similar laws) pursuant to the agreements related to the
transaction.     
 
  The swap market has grown substantially in recent years with a large number
of banks and investment banking firms acting both as principals and as agents
utilizing standardized swap documentation. Caps, collars and floors are more
recent innovations for which documentation is less standardized, and,
accordingly, they are less liquid than swaps.

                          INVESTMENT ADVISORY SERVICES
 
  Mitchell Hutchins acts as the investment adviser and administrator of each
Portfolio pursuant to a contract with the Fund dated April 21, 1988 as
supplemented by Fee Agreements dated May 1, 1989, December 30, 1991 and
September 1, 1993 ("Advisory Contract"). Under the Advisory Contract, the Fund
pays Mitchell Hutchins a fee for each Portfolio, computed daily and payable
monthly, according to the schedule set forth in the Prospectus.
   
  During the fiscal year ended December 31, 1994, Mitchell Hutchins earned
advisory fees in the amount of $103,238 for the Money Market Portfolio;
$105,843 for the Strategic Fixed Income Portfolio; $473,755 for the Global
Income Portfolio; $236,113 for the Asset Allocation Portfolio; $93,915 for the
Growth and Income Portfolio; $355,689 for the Growth Portfolio; $332,624 for
the Global Growth Portfolio; $23,797 for the High Grade Fixed Income Portfolio,
and $79,623 for the Aggressive Growth Portfolio.     
   
  During the fiscal year ended December 31, 1993, Mitchell Hutchins earned
advisory fees in the amount of $78,323 for the Money Market Portfolio; $132,588
for the Strategic Fixed Income Portfolio; $519,148 for the Global Income
Portfolio; $302,573 for the Asset Allocation Portfolio; $139,064 for the Growth
and Income Portfolio; $373,942 for the Growth Portfolio; and $201,799 for the
Global Growth Portfolio. During the period November 8, 1993 (commencement of
operations) to December 31, 1993, Mitchell Hutchins earned advisory fees in the
amount of $291 for the High Grade Fixed Income Portfolio. During the period
November 2, 1993 (commencement of operations) to December 31, 1993, Mitchell
Hutchins earned advisory fees in the amount of $948 for the Aggressive Growth
Portfolio.     
   
  The Advisory Contract authorizes Mitchell Hutchins to retain one or more sub-
advisers but does not require Mitchell Hutchins to do so. Under separate Sub-
Advisory Contracts dated September 1, 1993 with Mitchell Hutchins, Wolf, Webb,
Burk & Campbell ("WWBC") served as Sub-Adviser for the High Grade Fixed Income
Portfolio and Nicholas-Applegate Capital Management ("Nicholas-Applegate")
served as Sub-Adviser for the Aggressive Growth Portfolio. Under a Sub-Advisory
Contract dated May 26, 1994 with Mitchell Hutchins, Mitchell Hutchins
Institutional Investors Inc. ("MHII") served as sub-adviser for the Growth and
Income Portfolio. Pursuant to such Sub-Advisory Contracts, for the fiscal year
ended December 31, 1994, Mitchell Hutchins paid (or accrued) sub-advisory fees
of $14,277, $49,765 and $27,400 to WWBC for the High Grade Fixed Income
Portfolio, Nicholas-Applegate for the Aggressive Growth Portfolio, and MHII for
the Dividend Growth Portfolio, respectively. During the period November 8, 1993
(commencement of operations) to December 31, 1993 for the High Income Fixed
Income Portfolio and during the period November 2, 1993 (commencement of
operations) to December 31, 1993 for the Aggressive Growth Portfolio, WWBC and
Nicholas-Applegate, respectively, waived all their sub-advisory fees. The Sub-
Advisory Contract between Mitchell Hutchins and WWBC was terminated effective
July 21, 1995. On March 23, 1995, GE Investment Management Incorporated
commenced service as Sub-Adviser with respect to the Global Growth Portfolio
pursuant to a Sub-Advisory Contract with Mitchell Hutchins.     
   
  During the fiscal year ended December 31, 1992, Mitchell Hutchins earned
advisory fees in the amount of $109,037 for the Money Market Portfolio;
$115,977 for the Strategic Fixed Income Portfolio; $482,680 for the Global
Income Portfolio; $281,117 for the Asset Allocation Portfolio; $86,189 for the
Growth and Income Portfolio; $304,396 for the Growth Portfolio; and $177,294
for the Global Growth Portfolio.     
 
  Under the terms of the Advisory Contract, each Portfolio bears all expenses
incurred in its operation that are not specifically assumed by Mitchell
Hutchins. General expenses of the Fund not readily identifiable as belonging to
one of the Portfolios are allocated among the Portfolios by or under the
direction of the Fund's board of trustees in such manner as the board
determines to be fair and equitable. Expenses borne by each Portfolio include,
but are not limited to, the following (or the Portfolio's allocated share of
the following): (1) the cost (including brokerage commissions, if any) of
securities purchased or sold by the Portfolio and any losses incurred in
connection therewith; (2) fees payable to and expenses incurred on behalf of
the Portfolio by Mitchell Hutchins; (3) organizational expenses; (4) filing
fees and expenses relating to the
 
                                       23
<PAGE>
 
registration and qualification of the Fund or the shares of a Portfolio under
federal and state securities laws and maintenance of such registrations and
qualifications; (5) fees and salaries payable to the trustees who are not
"interested persons" of the Fund or Mitchell Hutchins; (6) all expenses
incurred in connection with the trustees' services, including travel expenses;
(7) taxes (including any income or franchise taxes) and governmental fees; (8)
costs of any liability, uncollectible items of deposit and other insurance and
fidelity bonds; (9) any costs, expenses or losses arising out of a liability of
or claim for damages or other relief asserted against the Fund or Portfolio for
violation of any law; (10) legal, accounting and auditing expenses, including
legal fees of special counsel for the trustees who are not interested persons
of the Fund; (11) charges of custodians, transfer agents and other agents; (12)
costs of preparing share certificates, if any; (13) expenses of setting in type
and printing prospectuses and supplements thereto, statements of additional
information and supplements thereto, reports and proxy materials for existing
shareholders and costs of mailing such materials to shareholders; (14) any
extraordinary expenses (including fees and disbursements of counsel) incurred
by the Fund or Portfolio; (15) fees, voluntary assessments and other expenses
incurred in connection with membership in investment company organizations;
(16) costs of mailing and tabulating proxies and costs of meetings of
shareholders, the board and any committees thereof; (17) the cost of investment
company literature and other publications provided to the trustees and
officers; and (18) costs of mailing, stationery and communications equipment.
 
  Under the Advisory Contract, Mitchell Hutchins will not be liable for any
error of judgment or mistake of law or for any loss suffered by the Fund in
connection with the performance of the Advisory Contract, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part
of Mitchell Hutchins in the performance of its duties or from reckless
disregard of its duties and obligations thereunder. Under each Sub-Advisory
Contract, the Sub-Adviser will not be liable for any error of judgment or
mistake of law or for any loss suffered by the Fund, the Portfolio, its
shareholders or Mitchell Hutchins in connection with the Sub-Advisory Contract,
except any liability to the Fund, the Portfolio, its shareholders or Mitchell
Hutchins to which the Sub-Adviser would otherwise be subject by reason of
willful misfeasance, bad faith, gross negligence on its part in the performance
of its duties or from reckless disregard by it of its obligations and duties
under the Sub-Advisory Contract.
 
  The Advisory Contract terminates automatically upon assignment and is
terminable at any time without penalty by the Fund's board of trustees or by
vote of the holders of a majority of the Portfolio's outstanding voting
securities on 60 days' written notice to Mitchell Hutchins or by Mitchell
Hutchins on 60 days' written notice to the Fund. Each Sub-Advisory Contract
terminates automatically upon its assignment or the termination of the Advisory
Contract and is terminable at any time without penalty by the board of trustees
or by vote of the holders of a majority of the Portfolio's outstanding voting
securities on 60 days' notice to the Sub-Adviser, or by the Sub-Adviser on 120
days' written notice to Mitchell Hutchins. The Sub-Advisory Contract may also
be terminated by Mitchell Hutchins (1) upon material breach by the Sub-Adviser
of its representations and warranties; (2) if the Sub-Adviser becomes unable to
discharge its duties and obligations under the Sub-Advisory Contract or (3) on
120 days' notice to the Sub-Adviser.
 
                             PORTFOLIO TRANSACTIONS
 
  Subject to policies established by the Fund's board of trustees, Mitchell
Hutchins or the applicable Sub-Adviser is responsible for the execution of
portfolio transactions and the allocation of brokerage transactions for each
Portfolio. In executing portfolio transactions, Mitchell Hutchins or the
applicable Sub-Adviser seeks to obtain the best net results for each Portfolio
taking into account such factors as the price (including the applicable
brokerage commission or dealer spread), size of the order, difficulty of
execution and operational facilities of the firm involved. Prices paid to
dealers in principal transactions through which most debt securities and some
equity securities are traded generally include a "spread," which is the
difference between the prices at which the dealer is willing to purchase and
sell a specific security at that time. Each Portfolio may invest in securities
traded in the OTC markets and will engage primarily in transactions with the
dealers
 
                                       24
<PAGE>
 
   
who make markets in such securities, unless a better price or execution could
be obtained by using a broker. While Mitchell Hutchins or the applicable Sub-
Adviser generally seeks reasonably competitive commission rates, payment of the
lowest commission is not necessarily consistent with obtaining the best net
results. During the fiscal year ended December 31, 1992, the Money Market,
Strategic Fixed Income, and Global Income Portfolios paid no commissions, while
the Asset Allocation, Growth and Income, Growth, and Global Growth Portfolios
paid aggregate commissions totalling $40,643, $34,551, $281,467, and $44,608,
respectively. During the fiscal year ended December 31, 1993, the Money Market,
Strategic Fixed Income, Global Income, High Grade Fixed Income and Aggressive
Growth Portfolios paid no commissions, while the Asset Allocation, Growth and
Income, Growth and Global Growth Portfolios paid aggregate commissions
totalling $74,851, $32,158, $32,332 and $442,008, respectively. During the
fiscal year ended December 31, 1994, the Money Market, Strategic Fixed Income,
High Grade Fixed Income, and Global Income Portfolios paid no commissions,
while the Asset Allocation, Growth and Income, Growth, Global Growth and
Aggressive Growth Portfolios paid aggregate commissions totalling $63,641,
$45,863, $37,100, $397,060, and $49,178, respectively.     
   
  The Fund has no obligation to deal with any broker or group of brokers in the
execution of portfolio transactions. The Fund contemplates that, consistent
with the policy of obtaining the best net results, a substantial amount of the
Portfolios' brokerage transactions may be conducted through Mitchell Hutchins
or its affiliates, including PaineWebber. The Fund's board of trustees has
adopted procedures in conformity with Rule 17e-1 under the 1940 Act to ensure
that all brokerage commissions paid to Mitchell Hutchins or its affiliates are
fair and reasonable. Specific provisions included in the Advisory Contract
authorize Mitchell Hutchins and any of its affiliates that is a member of a
national securities exchange to effect securities transactions for the
Portfolios on such exchange and to retain compensation in connection with such
transactions. Any such transactions will be effected and related compensation
paid in accordance with applicable SEC regulations. During the fiscal year
ended December 31, 1992, Asset Allocation Portfolio paid $420, Growth and
Income Portfolio paid $966 and Growth Portfolio paid $1,509 in brokerage
commissions to PaineWebber. During the fiscal year ended December 31, 1993,
Asset Allocation Portfolio paid $1,274, Growth and Income Portfolio paid $2,283
and Growth Portfolio paid $595 in brokerage commissions to PaineWebber. During
the fiscal year ended December 31, 1994, Asset Allocation Portfolio paid $720
in brokerage commissions to PaineWebber, representing 1.13% of the aggregate
brokerage commissions paid by that Portfolio and 1.61% of the aggregate dollar
amount of transactions involving the payment of commissions. During the fiscal
year ended December 31, 1994, Growth and Income Portfolio paid $1,817 in
commissions to PaineWebber, representing 3.96% of the aggregate brokerage
commissions paid by that Portfolio and 5.2% of the aggregate dollar amount of
transactions involving the payment of commissions. During the fiscal year ended
December 31, 1994, Growth Portfolio paid $600 in brokerage commissions to
PaineWebber, representing 1.61% of the aggregate brokerage commissions paid by
that Portfolio and 1.03% of the aggregate dollar amount of transactions
involving the payment of commissions. During the fiscal year ended December 31,
1994, Global Growth Portfolio paid $1,137 in commissions to PaineWebber,
representing 0.01% of the aggregate brokerage commissions paid by that
Portfolio and 0.01% of the aggregate dollar amount of transactions involving
the payment of commissions. The other Portfolios did not pay any brokerage
commissions to PaineWebber or any other affiliate of Mitchell Hutchins during
the last three fiscal years.     
 
  Transactions in futures contracts are executed through futures commission
merchants ("FCMs") who receive brokerage commissions for their services. The
Fund's procedures in selecting FCMs to execute the Portfolios' transactions in
futures contracts, including procedures permitting the use of Mitchell Hutchins
and its affiliates, are similar to those in effect with respect to brokerage
transactions in securities.
 
  Consistent with the interest of each Portfolio and subject to the review of
the Fund's board of trustees, Mitchell Hutchins or the applicable Sub-Adviser
may cause a Portfolio to purchase and sell portfolio securities from and to
brokers who provide the Portfolio with research, analysis, advice and similar
services. In return for such services, the Portfolio may pay to those brokers a
higher commission than may be charged by other brokers, provided that Mitchell
Hutchins or the applicable Sub-Adviser determines in good faith
 
                                       25
<PAGE>
 
   
that such commission is reasonable in terms either of that particular
transaction or of the overall responsibility of Mitchell Hutchins or the
applicable Sub-Adviser to the Portfolio and its other clients and that the
total commissions paid by the Portfolio will be reasonable in relation to the
benefits to the Portfolio over the long term. During the fiscal year ended
December 31, 1994, the Asset Allocation, Growth and Income, Growth and Global
Growth Portfolios directed $5,868,328, $6,851,516, $1,631,799 and $4,817,215,
respectively, in portfolio transactions to brokers chosen because they provide
research and analysis, for which these Portfolios paid $9,241, $8,767, $1,890
and $21,912, respectively, in commissions. During the fiscal year ended
December 31, 1994, the Aggressive Growth Portfolio paid $36,542 in commissions
on portfolio transactions directed to brokers chosen because they provide
research and analysis. During the same period, no other Portfolio paid any
brokerage commissions to brokers chosen because they provide research and
analysis.     
 
  For purchases or sales with broker-dealer firms which act as principal,
Mitchell Hutchins seeks best execution. Although Mitchell Hutchins may receive
certain research or execution services in connection with these transactions,
Michell Hutchins will not purchase securities at a higher price or sell
securities at a lower price than would otherwise be paid if no weight was
attributed to the services provided by the executing dealer. Moreover,
Mitchell Hutchins will not enter into any explicit soft dollar arrangements
relating to principal transactions and will not receive in principal
transactions the types of services which could be purchased for hard dollars.
Mitchell Hutchins may engage in agency transactions in OTC equity and debt
securities in return for research and execution services. These transactions
are entered into only in compliance with procedures ensuring that the
transaction (including commissions) is at least as favorable as it would have
been if effected directly with a market-maker that did not provide research or
execution services. These procedures include Mitchell Hutchins receiving
multiple quotes from dealers before executing the transaction on an agency
basis.
   
  Information and research received from such brokers and dealers will be in
addition to, and not in lieu of, the services required to be performed by
Mitchell Hutchins or the applicable Sub-Adviser under the Advisory Contract or
Sub-Advisory Contract. Research services furnished by brokers or dealers
through which or with which the Portfolios effect securities transactions may
be used by Mitchell Hutchins or the applicable Sub-Adviser in advising other
funds or accounts and, conversely, research services furnished to Mitchell
Hutchins or the applicable Sub-Adviser in connection with these other funds or
accounts may be used in advising the Portfolios.     
 
  Investment decisions for each Portfolio and for other investment accounts
managed by Mitchell Hutchins or the applicable Sub-Adviser are made
independently of each other in light of differing considerations for the
various accounts. However, the same investment decision may occasionally be
made for a Portfolio and one or more of such accounts. In such cases,
simultaneous transactions are inevitable. Purchases or sales are then averaged
as to price and allocated between the Portfolio and such other account(s) as
to amount according to a formula deemed equitable to the Portfolio and such
account(s). While in some cases this practice could have a detrimental effect
upon the price or value of the security as far as a Portfolio is concerned, or
upon its ability to complete its entire order, in other cases it is believed
that coordination and the ability to participate in volume transactions will
be beneficial to the Portfolio.
 
  The Portfolios will not purchase securities that are offered in
underwritings in which Mitchell Hutchins, the applicable Sub-Adviser or any of
their affiliates is a member of the underwriting or selling group, except
pursuant to procedures adopted by the Fund's board of trustees pursuant to
Rule 10f-3 under the 1940 Act. Among other things, these procedures require
that the commission or spread paid in connection with such a purchase be
reasonable and fair, that the purchase be at not more than the public offering
price prior to the end of the first business day after the date of the public
offering and that Mitchell Hutchins, the applicable Sub-Adviser or any
affiliate thereof not participate in or benefit from the sale to the Fund.
 
  PORTFOLIO TURNOVER. The turnover rate may vary greatly from year to year for
any Portfolio and will not be a limiting factor when Mitchell Hutchins or the
applicable Sub-Adviser deems portfolio changes appropriate. The annual
portfolio turnover rate is calculated by dividing the lesser of a Portfolio's
annual
 
                                      26
<PAGE>
 
   
sales or purchases of portfolio securities (exclusive of purchases or sales of
securities whose maturities at the time of acquisition were one year or less)
by the monthly average value of the securities except short-term securities in
the Portfolio during the year. For the fiscal years ended December 31, 1994 and
December 31, 1993, respectively, the portfolio turnover rates were 53.72% and
7.93% for the Strategic Fixed Income Portfolio, 97.45% and 68.60% for the
Global Income Portfolio, 112.32% and 60.36% for the Asset Allocation Portfolio,
27.35% and 34.95% for the Growth Portfolio, 175.34% and 266.96% for the Global
Growth Portfolio and 149.68% and 51.68% for the Growth and Income Portfolio.
For the fiscal period ended December 31, 1993, the portfolio turnover rate for
each of the High Grade Fixed Income Portfolio, and Aggressive Growth Portfolio
was 0.0%. For the fiscal year ended December 31, 1994 the Portfolio turnover
rate for the High Grade Fixed Income Portfolio, and Aggressive Growth Portfolio
was 35.86% and 90.42%, respectively.     
 
                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION
 
  The insurance company separate accounts purchase and redeem shares of each
Portfolio on each day on which the New York Stock Exchange, Inc. ("NYSE") is
open for trading ("Business Day") based on, among other things, the amount of
premium payments to be invested and surrendered and transfer requests to be
effected on that day pursuant to the variable contracts. Currently, the NYSE is
closed on the observance of New Year's Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
Such purchases and redemptions of the shares of each Portfolio are effected at
their respective net asset values per share determined as of the close of
trading (currently 4:00 p.m., eastern time) on that Business Day. Payment for
redemptions are made by the Fund within seven days thereafter. No fee is
charged the separate accounts when they purchase or redeem Portfolio shares.
 
  The Fund may suspend redemption privileges of shares of any Portfolio or
postpone the date of payment during any period (1) when the NYSE is closed or
trading on the NYSE is restricted as determined by the SEC, (2) when an
emergency exists, as defined by the SEC, that makes it not reasonably
practicable for the Fund to dispose of securities owned by it or fairly to
determine the value of its assets or (3) as the SEC may otherwise permit. The
redemption price may be more or less than the shareholder's cost, depending on
the market value of the Portfolio's securities at the time.
 
                              VALUATION OF SHARES
 
  Each Portfolio determines its net asset value as of the close of regular
trading (currently 4:00 p.m., eastern time) on the NYSE on each Monday through
Friday when the NYSE is open.
   
  Securities that are listed on U.S. and foreign stock exchanges are valued at
the last sale price on the day the securities are being valued or, lacking any
sales on such day, at the last available bid price. In cases where securities
are traded on more than one exchange, the securities are generally valued on
the exchange considered by Mitchell Hutchins or the applicable Sub-Adviser as
the primary market. Securities traded in the OTC market and listed on Nasdaq
are valued at the last available sale price listed on Nasdaq at 4:00 p.m.,
eastern time; other OTC securities are valued at the last available bid price
prior to the time of valuation.     
   
  When market quotations are readily available, the debt securities of the
Portfolios (with the exception of the Money Market Portfolio) are valued based
upon market quotations, provided such quotations adequately reflect, in the
judgment of Mitchell Hutchins or the applicable Sub-Adviser, the fair value of
the securities. The amortized cost method of valuation generally is used with
respect to debt obligations with 60 days or less remaining to maturity unless
the Fund's board of trustees determines that this does not represent fair
value. When market quotations for options and futures positions held by the
Portfolios are readily available, those positions are valued based upon such
quotations. Market quotations are not generally available for options traded in
the OTC market. When market quotations for options and futures positions, or
any other securities or assets of the Portfolios, are not available, they are
valued at fair value as determined in good     
 
                                       27
<PAGE>
 
faith by or under the direction of the Fund's board of trustees. When
practicable, such determinations are based upon appraisals received from a
pricing service using a computerized matrix system or appraisals derived from
information concerning the security or similar securities received from
recognized dealers in those securities.
 
  All securities quoted in foreign currencies are valued daily in U.S. dollars
on the basis of the foreign currency exchange rates prevailing at the time such
valuation is determined. Foreign currency exchange rates generally are
determined prior to the close of the NYSE. Occasionally, events affecting the
value of foreign securities and such exchange rates occur between the time at
which they are determined and the close of the NYSE, which events would not be
reflected in the computation of a Portfolio's net asset value. If events
materially affecting the value of such securities or currency exchange rates
occurred during such time period, the securities will be valued at their fair
value as determined in good faith by or under the direction of the board of
trustees. The foreign currency exchange transactions of the Government, Global
Income and Global Growth Portfolios conducted on a spot (that is, cash) basis
are valued at the spot rate for purchasing or selling currency prevailing on
the foreign exchange market. This rate under normal market conditions differs
from the prevailing exchange rate in an amount generally less than one-tenth of
one percent due to the costs of converting from one currency to another.
 
  The Money Market Portfolio values its portfolio securities in accordance with
the amortized cost method of valuation under Rule 2a-7 under the 1940 Act. To
use amortized cost to value its portfolio securities, the Portfolio must adhere
to certain conditions under that Rule relating to its investments, some of
which are discussed in the Prospectus. Amortized cost is an approximation of
market value, whereby the difference between acquisition cost and value at
maturity is amortized on a straight-line basis over the remaining life of the
instrument. The effect of changes in the market value of a security as a result
of fluctuating interest rates is not taken into account and thus the amortized
cost method of valuation may result in the value of a security being higher or
lower than its actual market value. In the event that a large number of
redemptions takes place at a time when interest rates have increased, the
Portfolio might have to sell portfolio securities prior to maturity and at a
price that might not be as desirable as the value at maturity.
 
  The Fund's board of trustees has established procedures for the purpose of
maintaining a constant net asset value of $1.00 per share for the Money Market
Portfolio, which include a review of the extent of any deviation of net asset
value per share, based on available market quotations, from the $1.00 amortized
cost per share. Should that deviation exceed 1/2 of 1%, the trustees will
promptly consider whether any action should be initiated to eliminate or reduce
material dilution or other unfair results to shareholders. Such action may
include redeeming shares in kind, selling portfolio securities prior to
maturity, reducing or withholding dividends and utilizing a net asset value per
share as determined by using available market quotations. The Money Market
Portfolio will maintain a dollar-weighted average portfolio maturity of 90 days
or less and will not purchase any instrument with a remaining maturity greater
than 13 months, will limit portfolio investments, including repurchase
agreements, to those U.S. dollar-denominated instruments that are of high
quality and that the trustees determine present minimal credit risks as advised
by Mitchell Hutchins and will comply with certain reporting and recordkeeping
procedures. There is no assurance that constant net asset per share value will
be maintained. In the event amortized cost ceases to represent fair value, the
board will take appropriate action.
 
  In determining the approximate market value of portfolio investments, the
Fund may employ outside organizations, which may use a matrix or formula method
that takes into consideration market indices, matrices, yield curves and other
specific adjustments. This may result in the securities being valued at a price
different from the price that would have been determined had the matrix or
formula method not been used. All cash, receivables and current payables are
carried at their face value. Other assets, if any, are valued at fair value as
determined in good faith by or under the direction of the board of trustees.

<PAGE>
 
                                     TAXES
 
  Shares of the Portfolios are offered only to insurance company separate
accounts that fund certain variable annuity and life insurance contracts
("Contracts"). See the applicable Contract prospectus for a discussion of the
special taxation of insurance companies with respect to such accounts and of
the Contract holders.
   
  Each Portfolio is treated as a separate corporation for federal income tax
purposes. In order to continue to qualify for treatment as a regulated
investment company ("RIC") under the Internal Revenue Code, each Portfolio must
distribute to its shareholders for each taxable year at least 90% of its
investment company taxable income (consisting generally of net investment
income, net short-term capital gain and, for certain Portfolios, net gains from
certain foreign currency transactions) ("Distribution Requirement") and must
meet several additional requirements. With respect to each Portfolio, these
requirements include the following: (1) the Portfolio must derive at least 90%
of its gross income each taxable year from dividends, interest, payments with
respect to securities loans and gains from the sale or other disposition of
securities or foreign currencies, or other income (including gains from
options, futures or forward currency contracts) derived with respect to its
business of investing in securities or those currencies ("Income Requirement");
(2) the Portfolio must derive less than 30% of its gross income each taxable
year from the sale or other disposition of securities, or any of the following,
that were held for less than three months--options or futures (other than those
on foreign currencies), or foreign currencies (or options, futures or forward
contracts thereon) that are not directly related to the Portfolio's principal
business of investing in securities (or options and futures with respect to
securities) ("Short-Short Limitation"); (3) at the close of each quarter of the
Portfolio's taxable year, at least 50% of the value of its total assets must be
represented by cash and cash items, U.S. government securities, securities of
other RICs and other securities, with these other securities limited, in
respect of any one issuer, to an amount that does not exceed 5% of the value of
the Portfolio's total assets and that does not represent more than 10% of the
issuer's outstanding voting securities; and (4) at the close of each quarter of
the Portfolio's taxable year, not more than 25% of the value of its total
assets may be invested in securities (other than U.S. government securities or
the securities of other RICs) of any one issuer.     
   
  As noted in the Prospectus, each Portfolio must, and intends to continue to,
comply with the diversification requirements imposed by section 817(h) of the
Internal Revenue Code and the regulations thereunder. These requirements, which
are in addition to the diversification requirements mentioned above, place
certain limitations on the proportion of each Portfolio's assets that may be
represented by any single investment (which includes all securities of the same
issuer). For these purposes, each U.S. government agency or instrumentality is
treated as a separate issuer.     
 
  The use of hedging and related income strategies, such as selling (writing)
and purchasing options and futures contracts and entering into forward currency
contracts, involves complex rules that will determine for income tax purposes
the character and timing of recognition of the gains and losses a Portfolio
realizes in connection therewith. Income from the disposition of foreign
currencies (except certain gains therefrom that may be excluded by future
regulations), and income from transactions in options, futures and forward
currency contracts derived by a Portfolio with respect to its business of
investing in securities or foreign currencies, will qualify as permissible
income under the Income Requirement. However, income from the disposition of
options and futures contracts (other than those on foreign currencies) will be
subject to the Short-Short Limitation if they are held for less than three
months. Income from the disposition of foreign currencies, and options, futures
and forward contracts on foreign currencies, that are not directly related to a
Portfolio's principal business of investing in securities (or options and
futures with respect to securities) also will be subject to the Short-Short
Limitation if they are held for less than three months.
 
  If a Portfolio satisfies certain requirements, any increase in value of a
position that is part of a "designated hedge" will be offset by any decrease in
value (whether realized or not) of the offsetting hedging position during the
period of the hedge for purposes of determining whether the Portfolio satisfies
the Short-Short Limitation. Thus, only the net gain (if any) from the
designated hedge will be included in gross income
 
                                       29
<PAGE>
 
for purposes of that limitation. Each Portfolio will consider whether it should
seek to qualify for this treatment for its hedging transactions. To the extent
a Portfolio does not qualify for this treatment, it may be forced to defer the
closing out of certain options, futures and forward contracts beyond the time
when it otherwise would be advantageous to do so, in order for the Portfolio to
continue to qualify as a RIC.
 
  Dividends and interest received by a Portfolio may be subject to income,
withholding or other taxes imposed by foreign countries and U.S. possessions
that would reduce the yield on that Portfolio's securities. Tax conventions
between certain countries and the United States may reduce or eliminate these
foreign taxes, however, and many foreign countries do not impose taxes on
capital gains in respect of investments by foreign investors.
 
  Any Portfolio that may purchase or hold equity securities may invest in
"passive foreign investment companies" ("PFICs"). A PFIC is a foreign
corporation that, in general, meets either of the following tests: (1) at least
75% of its gross income is passive or (2) an average of at least 50% of its
assets produce, or are held for the production of, passive income. Under
certain circumstances, a Portfolio that holds stock of a PFIC will be subject
to federal income tax on a portion of any "excess distribution" received on the
stock or of any gain on disposition of the stock (collectively "PFIC income"),
plus interest thereon, even if the Portfolio distributes the PFIC income as a
taxable dividend to its shareholders. The balance of the PFIC income will be
included in the Portfolio's investment company taxable income and, accordingly,
will not be taxable to it to the extent that income is distributed to its
shareholders.
   
  If a Portfolio invests in a PFIC and elects to treat the PFIC as a "qualified
electing fund," then in lieu of the foregoing tax and interest obligation, the
Portfolio will be required to include in income each year its pro rata share of
the qualified electing fund's annual ordinary earnings and net capital gain
(the excess of net long-term capital gain over net short-term capital loss),
even if they are not received by the Portfolio; those amounts most likely would
have to be distributed to the Portfolio's shareholders to satisfy the
Distribution Requirement. In most instances it will be very difficult, if not
impossible, to make this election because of certain requirements thereof.     
 
  Pursuant to proposed regulations, open-end RICs, such as the Portfolios,
would be entitled to elect to "mark-to-market" their stock in certain PFICs.
"Marking-to-market," in this context, means recognizing as gain for each
taxable year the excess, as of the end of that year, of the fair market value
of each such PFIC's stock over the owner's adjusted basis in that stock
(including mark-to-market gain for each prior year for which an election was in
effect).
 
  The foregoing is only a general summary of some of the important federal
income tax considerations generally affecting the Portfolios and their
shareholders. No attempt is made to present a complete explanation of the
federal tax treatment of the Portfolios' activities, and this discussion is not
intended as a substitute for careful tax planning. Accordingly, potential
investors are urged to consult their own tax advisers for more detailed
information and for information regarding any state, local or foreign taxes
applicable to the Portfolios and to dividends and other distributions
therefrom.
 
                                   DIVIDENDS
 
  MONEY MARKET PORTFOLIO. Shares begin earning dividends on the day of
purchase; dividends are accrued to shareholder accounts daily and are
automatically reinvested in Portfolio shares monthly. The Portfolio does not
expect to realize net capital gain. In the event of a redemption of all of the
shares held by a shareholder, all accrued dividends declared on the shares up
to the date of redemption are credited to the shareholder's account.
 
  The Fund's board of trustees may revise the above dividend policy, or
postpone the payment of dividends, if the Portfolio should have or anticipate
any large unexpected expense, loss or fluctuation in net
 
                                       30
<PAGE>
 
assets that, in the opinion of the board, might have a significant adverse
effect on shareholders. To date, no situation has arisen to cause the board of
trustees to take any such action.
 
                               OTHER INFORMATION
   
  Prior to August 14, 1995, the name of the Growth and Income Portfolio was
"Dividend Growth Portfolio." Prior to September 21, 1995, the name of the
Strategic Fixed Income Portfolio was "Government Portfolio" and the name of the
High Grade Fixed Income Portfolio was "Fixed Income Portfolio."     
 
  The Fund is an entity of the type commonly known as a "Massachusetts business
trust." Under Massachusetts law, shareholders could, under certain
circumstances, be held personally liable for the obligations of the Fund or a
Portfolio. However, the Fund's Declaration of Trust disclaims shareholder
liability for acts or obligations of the Fund or any Portfolio and requires
that notice of such disclaimer be given in each note, bond, contract,
instrument, certificate or undertaking made or issued by the trustees or by any
officers or officer by or on behalf of the Fund, the trustees or any of them in
connection with the Fund. The Declaration of Trust provides for indemnification
from Fund or Portfolio property, as appropriate, for all losses and expenses of
any shareholder held personally liable for the obligations of the Fund or
Portfolio. Thus, the risk of a shareholder's incurring financial loss on
account of shareholder liability is limited to circumstances in which the Fund
or Portfolio itself would be unable to meet its obligations, a possibility that
Mitchell Hutchins believes is remote and not material. Upon payment of any
liability incurred by a shareholder of a Portfolio, the shareholder paying such
liability will be entitled to reimbursement from the general assets of the
Portfolio. The trustees intend to conduct the operations of the Fund so as to
avoid, as far as possible, ultimate liability of the shareholders for
liabilities of the Fund and the Portfolios.

                DESCRIPTION OF COMMERCIAL PAPER AND BOND RATINGS
 
  COMMERCIAL PAPER RATINGS. Moody's employs the designation "Prime-1," "Prime-
2" and "Prime-3" to indicate the repayment capacity of issuers of commercial
paper. Issuers rated Prime-1 have a superior capacity for repayment of short-
term promissory obligations. Prime-1 repayment capacity will normally be
evidenced by the following characteristics: leading market positions in well-
established industries; high rates of return on funds employed; conservative
capitalization structures with moderate reliance on debt and ample asset
protection; broad margins in earnings coverage of fixed financial charges and
high internal cash generation; well-established access to a range of financial
markets and assured sources of alternate liquidity. Issuers rated Prime-2 have
a strong capacity for repayment of short-term promissory obligations. This will
normally be evidenced by many of the characteristics cited above but to a
lesser degree. Earnings trends and coverage ratios, while sound, will be more
subject to variation. Capitalization characteristics, while still appropriate,
may be more affected by external conditions. Ample alternate liquidity is
maintained. Issuers rated Prime-3 have an acceptable capacity for repayment of
short-term promissory obligations. The effect of industry characteristics and
market composition may be more pronounced. Variability in earnings and
profitability may result in changes in the level of debt protection
measurements and the requirement for relatively high financial leverage.
Adequate alternate liquidity is maintained. Not Prime. Issuers assigned this
rating do not fall within any of the Prime rating categories.
 
  S&P's ratings of commercial paper are graded into four categories ranging
from "A" for the highest quality obligations to "D" for the lowest. A--Issues
assigned this highest rating are regarded as having the greatest capacity for
timely payment. Issues in this category are delineated with numbers 1, 2, and 3
to indicate the relative degree of safety. A-1--This designation indicates that
the degree of safety regarding timely payment is either overwhelming or very
strong. Those issues determined to possess overwhelming safety characteristics
are denoted with a plus (+) sign designation. A-2--Capacity for timely payments
on issues with this designation is strong. However, the relative degree of
safety is not as high as for issues designated "A-1." A-3--Issues carrying this
designation have a satisfactory capacity for timely payment. They are, however,
somewhat more vulnerable to the adverse effects of changes in circumstances
than obligations carrying the higher designations. B--Issues rated B are
regarded as having only an adequate capacity for timely payment. However, such
capacity may be damaged by changing conditions or short-term adversities. C--
This rating is assigned to short-term debt obligations with a doubtful capacity
for payment. D--This rating indicates that the issue is either in default or is
expected to be in default upon maturity.
 
  CORPORATE DEBT SECURITIES. Moody's rates the long-term debt securities issued
by various entities from "Aaa" to "D". Aaa--Best quality. These securities
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--High quality by
all standards. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities, 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--Upper medium grade obligations. These bonds possess many favorable
investment attributes. 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--Medium grade obligations. Interest
payments and principal security appear adequate for the present but certain
protective elements may be lacking or may be characteristically unreliable over
any great length of time. Such bonds lack outstanding investment
characteristics and, in fact, have speculative characteristics as well. Ba--
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 thereby not well safeguarded during both good and bad times over
the future. Uncertainty of position characterizes bonds in this class. 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--Poor standing. Such
issues may be in default or there may
 
                                       32
<PAGE>
 
be present elements of danger with respect to principal or interest. Ca--
Obligations which are speculative in a high degree. Such issues are often in
default or have other marked shortcomings. C--Lowest rated class of bonds;
issues so rated can be regarded as having extremely poor prospects of ever
attaining any real investment standing.
 
  Note: Moody's may apply numerical modifiers, 1, 2 and 3 in each generic
rating classification from Aa through B in its corporate bond 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 the
modifier 3 indicates that the issue ranks in the lower end of its generic
rating category.
 
  S&P also rates the long-term debt securities of various entities in
categories ranging from "AAA" to "D" according to quality. AAA--Highest grade.
Capacity to pay interest and repay principal extremely strong. AA--High grade.
Debt rated AA has a very strong capacity to pay interest and repay principal
and differs from AAA issues only in a small degree. 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. BBB--Regarded as having adequate capacity to pay interest and repay
principal. Whereas these bonds normally exhibit adequate protection parameters,
adverse economic conditions or changing circumstances are more likely to lead
to a weakened capacity to pay interest and repay principal than for debt in
higher rated categories. BB, B, CCC, CC, C--Regarded, on balance, as
predominantly speculative with respect to capacity to pay interest and repay
principal in accordance with the terms of the obligation. BB indicates the
lowest degree of speculation and C the highest degree of speculation. While
such debt will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions. CI--Reserved for income bonds on which no interest is being paid.
D--In default, and payment of interest and/or repayment of principal is in
arrears.
 
  Plus (+) or Minus (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

                      INVESTMENT POLICIES AND LIMITATIONS
 
  The following supplements the information contained in the Fund's Prospectus
concerning the investment policies and limitations of the above-referenced
seven Portfolios.
   
  SPECIAL CONSIDERATIONS RELATING TO FOREIGN SECURITIES. As noted in the
Prospectus, the Global Income Portfolio, Global Growth Portfolio and Strategic
Fixed Income Portfolio each invests in securities of foreign issuers. In
addition, the Asset Allocation Portfolio, Growth and Income Portfolio and
Growth Portfolio each may invest in U.S. dollar-denominated securities of
foreign issuers. Many of the foreign securities held by these Portfolios are
not registered with the Securities and Exchange Commission ("SEC"), nor are the
issuers thereof subject to its reporting requirements. Accordingly, there may
be less publicly available information concerning foreign issuers of securities
held by those Portfolios than is available concerning U.S. companies. Foreign
companies are not generally subject to uniform accounting, auditing and
financial reporting standards or to other regulatory requirements comparable to
those applicable to U.S. companies.     
   
  In addition to purchasing securities of foreign issuers in foreign markets,
the Global Income and Global Growth Portfolios may invest in American
Depository Receipts ("ADRs"), European Depository Receipts ("EDRs") or other
securities convertible into securities of companies based in foreign countries.
These securities may not necessarily be denominated in the same currency as the
securities into which they may be converted. Generally, ADRs, in registered
form, are denominated in U.S. dollars and are designed for use in the U.S.
securities markets and EDRs, in bearer form, may be denominated in other
currencies and are designed for use in European securities markets. ADRs are
receipts typically issued by a U.S. bank or trust company evidencing ownership
of the underlying securities. EDRs are European receipts evidencing a similar
arrangement. The Asset Allocation, Growth and Income and Growth Portfolios
generally invest in securities of foreign companies only if such securities are
traded in the U.S. securities markets directly or through ADRs. For purposes of
the Fund's investment policies, ADRs and EDRs are deemed to have the same
classification as the underlying securities they represent. Thus, an ADR or EDR
evidencing ownership of common stock will be treated as common stock.     
 
  The Global Growth Portfolio anticipates that its brokerage transactions
involving securities of companies headquartered in countries other than the
United States will be conducted primarily on the principal exchanges of such
countries. Foreign security trading practices, including those involving
securities settlement where Portfolio assets may be released prior to receipt
of payment, may expose the Portfolio to increased risk in the event of a failed
trade or the insolvency of a foreign broker-dealer. Transactions on foreign
exchanges are usually subject to fixed commissions that are generally higher
than negotiated commissions on U.S. transactions, although the Portfolio will
endeavor to achieve the best net results in effecting portfolio transactions.
There is generally less government supervision and regulation of exchanges and
brokers in foreign countries than in the United States.
 
  Investment income on certain foreign securities may be subject to foreign
withholding or other taxes that could reduce the return on these securities.
Tax treaties between the United States and foreign countries, however, may
reduce or eliminate the amount of foreign taxes to which the Portfolio would be
subject.
 
  SOVEREIGN DEBT. Investment in debt securities issued by foreign governments
and their political subdivisions or agencies ("Sovereign Debt") involves
special risks. The issuer of the debt or the governmental authorities that
control the repayment of the debt may be unable or unwilling to repay principal
and/or interest when due in accordance with the terms of such debt, and the
Portfolio may have limited legal recourse in the event of a default.
 
  Sovereign Debt differs from debt obligations issued by private entities in
that, generally, remedies for defaults must be pursued in the courts of the
defaulting party. Legal recourse is therefore somewhat
 
                                       3
<PAGE>
 
diminished. Political conditions, especially a sovereign entity's willingness
to meet the terms of its debt obligations, are of considerable significance.
Also, there can be no assurance that the holders of commercial bank debt issued
by the same sovereign entity may not contest payments to the holders of
Sovereign Debt in the event of default under commercial bank loan agreements.
 
  A sovereign debtor's willingness or ability to repay principal and interest
due in a timely manner may be affected by, among other factors, its cash flow
situation, the extent of its foreign reserves, the availability of sufficient
foreign exchange on the date a payment is due, the relative size of the debt
service burden to the economy as a whole, the sovereign debtor's policy toward
principal international lenders and the political constraints to which a
sovereign debtor may be subject. Increased protectionism on the part of a
country's trading partners, or political changes in those countries, could also
adversely affect its exports. Such events could diminish a country's trade
account surplus, if any, or the credit standing of a particular local
government or agency.
 
  The occurrence of political, social or diplomatic changes in one or more of
the countries issuing Sovereign Debt could adversely affect a Portfolio's
investments. Political changes or a deterioration of a country's domestic
economy or balance of trade may affect the willingness of countries to service
their Sovereign Debt. While Mitchell Hutchins or the applicable Sub-Adviser
manages the Portfolios' investments in a manner that is intended to minimize
the exposure to such risks, there can be no assurance that adverse political
changes will not cause a Portfolio to suffer a loss of interest or principal on
any of its holdings.
   
  FOREIGN CURRENCY TRANSACTIONS. Although each of the Strategic Fixed Income,
Global Income and Global Growth Portfolios values its assets daily in U.S.
dollars, it does not intend to convert its holdings of foreign currencies to
U.S. dollars on a daily basis. The Portfolios' foreign currencies may be held
as "foreign currency call accounts" at foreign branches of foreign or domestic
banks. These accounts bear interest at negotiated rates and are payable upon
relatively short demand periods. If a bank became insolvent, a Portfolio could
suffer a loss of some or all of the amounts deposited. The Portfolios may
convert foreign currency to U.S. dollars from time to time. Although foreign
exchange dealers generally do not charge a stated commission or fee for
conversion, the prices posted generally include a "spread," which is the
difference between the prices at which the dealers are buying and selling
foreign currencies.     
   
  SELECTION OF INVESTMENTS BY ASSET ALLOCATION PORTFOLIO. The money market
instruments in which the Asset Allocation Portfolio may invest include U.S.
Treasury bills and other obligations issued or guaranteed as to interest and
principal by the U.S. government, its agencies and instrumentalities;
obligations of U.S. banks (including certificates of deposit and bankers'
acceptances) having total assets at the time of purchase in excess of $1.5
billion and interest-bearing savings deposits in U.S. commercial and savings
banks in principal amounts at each such bank not greater than are fully insured
by the Federal Deposit Insurance Corporation, provided that the aggregate
amount of such deposits does not exceed 5% of the value of the Portfolio's
assets; commercial paper and other short-term corporate obligations; and
variable and floating rate securities and repurchase agreements. The Portfolio
may also hold cash.     
       
       
       
       
          
  The commercial paper and other short-term corporate obligations purchased by
the Portfolio will consist only of obligations of U.S. corporations that are
(1) rated at least Prime-2 by Moody's Investors Service ("Moody's") or A-2 by
Standard & Poor's ("S&P") (2) comparably rated by another nationally recognized
statistical rating organization ("NRSRO") or (3) unrated and determined by
Mitchell Hutchins to be of comparable quality. These obligations may include
variable amount master demand notes, which are unsecured obligations redeemable
upon notice that permit investment of fluctuating amounts at varying rates of
interest pursuant to direct arrangements with the issuer of the instrument.
Such obligations are usually unrated by a rating agency.     
 
                                       4
<PAGE>
 
  The Portfolio may purchase variable rate securities with remaining maturities
of one year or more issued by U.S. government agencies or instrumentalities or
guaranteed by the U.S. government. The Portfolio may also acquire certain
variable and floating rate instruments issued by U.S. companies. The yield of
these securities varies in relation to changes in specific money market rates
such as the prime rate. These changes are reflected in adjustments to the
yields of the variable rate securities at least semi-annually, and different
securities may have different adjustment rates.
 
  ADJUSTABLE RATE AND FLOATING RATE MORTGAGE-BACKED SECURITIES. Certain
Portfolios may invest in adjustable rate mortgage ("ARM") and floating rate
mortgage-backed securities. Because the interest rates on ARM and floating rate
mortgage-backed securities are reset in response to changes in a specified
market index, the values of such securities tend to be less sensitive to
interest rate fluctuations than the values of fixed-rate securities. As a
result, during periods of rising interest rates, ARMs generally do not decrease
in value as much as fixed rate securities. Conversely, during periods of
declining interest rates, ARMs generally do not increase in value as much as
fixed rate securities. ARM mortgage-backed securities represent a right to
receive interest payments at a rate that is adjusted to reflect the interest
earned on a pool of ARMs. ARMs generally provide that the borrower's mortgage
interest rate may not be adjusted above a specified lifetime maximum rate or,
in some cases, below a minimum lifetime rate. In addition, certain ARMs provide
for limitations on the maximum amount by which the mortgage interest rate may
adjust for any single adjustment period. ARMs also may provide for limitations
on changes in the maximum amount by which the borrower's monthly payment may
adjust for any single adjustment period. In the event that a monthly payment is
not sufficient to pay the interest accruing on the ARM, any such excess
interest is added to the mortgage loan ("negative amortization"), which is
repaid through future monthly payments. If the monthly payment exceeds the sum
of the interest accrued at the applicable mortgage interest rate and the
principal payment that would have been necessary to amortize the outstanding
principal balance over the remaining term of the loan, the excess reduces the
principal balance of the ARM. Borrowers under ARMs experiencing negative
amortization may take longer to build up their equity in the underlying
property and may be more likely to default.
 
  The rates of interest payable on certain ARMs, and therefore on certain ARM
mortgage-backed securities, are based on indices, such as the one-year constant
maturity Treasury rate, that reflect changes in market interest rates. Others
are based on indices, such as the 11th District Federal Home Loan Bank Cost of
Funds index ("COFI"), that tend to lag behind changes in market interest rates.
The values of ARM mortgage-backed securities supported by ARMs that adjust
based on lagging indices tend to be somewhat more sensitive to interest rate
fluctuations than those reflecting current interest rate levels, although the
values of such ARM mortgage-backed securities still tend to be less sensitive
to interest rate fluctuations than fixed-rate securities.
 
  Floating rate mortgage-backed securities are classes of mortgage-backed
securities that have been structured to represent the right to receive interest
payments at rates that fluctuate in accordance with an index but that generally
are supported by pools comprised of fixed-rate mortgage loans. As with ARM
mortgage-backed securities, interest rate adjustments on Floating Rate
mortgage-backed securities may be based on indices that lag behind market
interest rates. Interest rates on floating rate mortgage-backed securities
generally are adjusted monthly. Floating rate mortgage-backed securities are
subject to lifetime interest rate caps, but they generally are not subject to
limitations on monthly or other periodic changes in interest rates or monthly
payments.
 
  SPECIAL CHARACTERISTICS OF MORTGAGE- AND ASSET-BACKED SECURITIES. Prepayments
on a pool of mortgage loans are influenced by a variety of economic,
geographic, social and other factors, including changes in mortgagors' housing
needs, job transfers, unemployment, mortgagors' net equity in the mortgaged
properties and servicing decisions. Generally, however, prepayments on fixed-
rate mortgage loans will increase during a period of falling interest rates and
decrease during a period of rising interest rates. Similar factors apply to
 
                                       5
<PAGE>
 
prepayments on asset-backed securities, but the receivables underlying asset-
backed securities generally are of a shorter maturity and thus are less likely
to experience substantial prepayments. Such securities, however, often provide
that for a specified time period the issuers will replace receivables in the
pool that are repaid with comparable obligations. If the issuer is unable to do
so, repayment of principal on the asset-backed securities may commence at an
earlier date. Mortgage- and asset-backed securities may decrease in value as a
result of increases in interest rates and may benefit less than other fixed-
income securities from declining interest rates because of the risk of
prepayment.
 
  ARMs also may be subject to a greater rate of prepayments in a declining
interest rate environment. For example, during a period of declining interest
rates, prepayments on ARMs could increase because the availability of fixed
mortgage loans at competitive interest rates may encourage mortgagers to "lock-
in" at a lower interest rate. Conversely, during a period of rising interest
rates, prepayments on ARMs might decrease. The rate of prepayments with respect
to ARMs has fluctuated in recent years.
 
  The rate of interest on mortgage-backed securities is lower than the interest
rates paid on the mortgages included in the underlying pool due to the annual
fees paid to the servicer of the mortgage pool for passing through monthly
payments to certificateholders and to any guarantor, and due to any yield
retained by the issuer. Actual yield to the holder may vary from the coupon
rate, even if adjustable, if the mortgage-backed securities are purchased or
traded in the secondary market at a premium or discount. In addition, there is
normally some delay between the time the issuer receives mortgage payments from
the servicer and the time the issuer makes the payments on the mortgage-backed
securities, and this delay reduces the effective yield to the holder of such
securities.
   
  ILLIQUID SECURITIES. Each Portfolio may invest up to 10% (15% for the
Strategic Fixed Income Portfolio) of its net assets in illiquid securities. The
term "illiquid securities" for this purpose means securities that cannot be
disposed of within seven days in the ordinary course of business at
approximately the amount at which a Portfolio has valued the securities and
includes, among other things, purchased over-the-counter ("OTC") options,
repurchase agreements maturing in more than seven days and restricted
securities other than those securities Mitchell Hutchins or the applicable Sub-
Adviser has determined are liquid pursuant to guidelines established by the
Fund's board of trustees. The assets used as cover for OTC options written by a
Portfolio will be considered illiquid unless the OTC options are sold to
qualified dealers who agree that the Portfolio may repurchase any OTC option it
writes at a maximum price to be calculated by a formula set forth in the option
agreement. The cover for an OTC option written subject to this procedure will
be considered illiquid only to the extent that the maximum repurchase price
under the option formula exceeds the intrinsic value of the option. Illiquid
restricted securities may be sold only in privately negotiated transactions or
in public offerings with respect to which a registration statement is in effect
under the Securities Act of 1933 ("1933 Act"). Restricted securities acquired
by the Strategic Fixed Income, Global Income and Global Growth Portfolios
include those that are subject to restrictions contained in the securities laws
of other countries. For these Portfolios, securities that are freely marketable
in the country where they are principally traded, but would not be freely
marketable in the United States, will not be considered illiquid. Where
registration is required, a Portfolio may be obligated to pay all or part of
the registration expenses and a considerable period may elapse between the time
of the decision to sell and the time it may be permitted to sell a security
under an effective registration statement. If, during such a period, adverse
market conditions were to develop, the Portfolio might obtain a less favorable
price than prevailed when it decided to sell.     
 
  Not all restricted securities are illiquid. In recent years a large
institutional market has developed for certain securities that are not
registered under the 1933 Act, including private placements, repurchase
agreements, commercial paper, foreign securities and corporate bonds and notes.
These instruments are often restricted securities because the securities are
sold in transactions not requiring registration. Institutional investors
generally will not seek to sell these instruments to the general public, but
instead will often depend either on an efficient institutional market in which
such unregistered securities can be readily resold or on an issuer's ability to
honor a demand for repayment. Therefore, the fact that there are contractual or
legal restrictions on resale to the general public or certain institutions is
not dispositive of the liquidity of such investments.
 
                                       6
<PAGE>
 
  Rule 144A under the 1933 Act establishes a "safe harbor" from the
registration requirements of the 1933 Act for resales of certain securities to
qualified institutional buyers. Institutional markets for restricted securities
have developed as a result of Rule 144A, providing both readily ascertainable
values for restricted securities and the ability to liquidate an investment to
satisfy share redemption orders. Such markets might include automated systems
for the trading, clearance and settlement of unregistered securities of
domestic and foreign issuers, such as the PORTAL System sponsored by the
National Association of Securities Dealers, Inc. An insufficient number of
qualified buyers interested in purchasing Rule 144A-eligible restricted
securities held by a Portfolio, however, could affect adversely the
marketability of such portfolio securities and a Portfolio might be unable to
dispose of such securities promptly or at favorable prices.
   
  The board of trustees has delegated the function of making day-to-day
determinations of liquidity to Mitchell Hutchins or the applicable Sub-Adviser,
pursuant to guidelines approved by the board. Mitchell Hutchins or the
applicable Sub-Adviser takes into account a number of factors in reaching
liquidity decisions, including but not limited to (1) the frequency of trades
for the security, (2) the number of dealers that make quotes for the security,
(3) the number of dealers that have undertaken to make a market in the
security, (4) the number of other potential purchasers and (5) the nature of
the security and how trading is effected (e.g., the time needed to sell the
security, how bids are solicited and the mechanics of transfer). Mitchell
Hutchins or the applicable Sub-Adviser monitors the liquidity of restricted
securities in each Portfolio and reports periodically on such decisions to the
board of trustees.     
   
  SECTION 4(2) PAPER. Commercial paper issues in which the Portfolios may
invest include securities issued by major corporations without registration
under the 1933 Act in reliance on the exemption from such registration afforded
by Section 3(a)(3) thereof, and commercial paper issued in reliance on the so-
called "private placement" exemption from registration which is afforded by
Section 4(2) of the 1933 Act ("Section 4(2) paper"). Section 4(2) paper is
restricted as to disposition under the federal securities laws in that any
resale must similarly be made in an exempt transaction. Section 4(2) paper is
normally resold to other institutional investors through or with the assistance
of investment dealers who make a market in Section 4(2) paper, thus providing
liquidity. Section 4(2) paper that is issued by a company that files reports
under the Securities Exchange Act of 1934 is generally eligible to be sold in
reliance on the safe harbor of Rule 144A described under "Illiquid Securities"
above. The Portfolios' 10% (15% for the Strategic Fixed Income Portfolio)
limitation on investments in illiquid securities includes Section 4(2) paper
other than Section 4(2) paper that Mitchell Hutchins or the applicable Sub-
Adviser has determined to be liquid pursuant to guidelines established by the
Fund's board of trustees. The board has delegated to Mitchell Hutchins or the
applicable Sub-Adviser the function of making day-to-day determinations of
liquidity with respect to Section 4(2) paper, pursuant to guidelines approved
by the board that require Mitchell Hutchins or the applicable Sub-Adviser to
take into account the same factors described under "Illiquid Securities" above
for other restricted securities and require Mitchell Hutchins or the applicable
Sub-Adviser to perform the same monitoring and reporting functions.     
 
  REPURCHASE AGREEMENTS. Repurchase agreements are transactions in which a
Portfolio purchases securities from a bank or recognized securities dealer and
simultaneously commits to resell the securities to the bank or dealer at an
agreed-upon date and price reflecting a market rate of interest unrelated to
the coupon rate or maturity of the purchased securities. The Portfolio
maintains custody of the underlying securities prior to their repurchase; thus,
the obligation of the bank or dealer to pay the repurchase price on the date
agreed to is, in effect, secured by such securities. If the value of these
securities is less than the repurchase price, plus any agreed-upon additional
amount, the other party to the agreement must provide additional collateral so
that at all times the collateral is at least equal to the repurchase price plus
any agreed-upon additional amount. The difference between the total amount to
be received upon repurchase of the securities and the price that was paid by
the Portfolio upon their acquisition is accrued as interest and included in the
Portfolio's net investment income.
 
                                       7
<PAGE>
 
   
  Repurchase agreements carry certain risks not associated with direct
investments in securities, including possible declines in the market value of
the underlying securities and delays and costs to a Portfolio if the other
party to a repurchase agreement becomes insolvent. Each Portfolio intends to
enter into repurchase agreements only with banks and dealers in transactions
believed by Mitchell Hutchins or the applicable Sub-Adviser to present minimum
credit risks in accordance with guidelines established by the Fund's board of
trustees. Mitchell Hutchins or the applicable Sub-Adviser will review and
monitor the creditworthiness of those institutions under the board's general
supervision.     
   
  REVERSE REPURCHASE AGREEMENTS. Each Portfolio may enter into reverse
repurchase agreements with banks and securities dealers up to an aggregate
value of not more than 5% (33 1/3% for the Strategic Fixed Income Portfolio and
10% for the Global Income Portfolio) of its total assets. Such agreements
involve the sale of securities held by the Portfolio subject to the Portfolio's
agreement to repurchase the securities at an agreed-upon date and price
reflecting a market rate of interest. Such agreements are considered to be
borrowings and may be entered into by Portfolios other than the Strategic Fixed
Income Portfolio only for temporary purposes. While a reverse repurchase
agreement is outstanding, a Portfolio's custodian segregates assets to cover
the amount of the Portfolio's obligations under the reverse repurchase
agreement. See "Investment Policies and Limitations--Segregated Accounts." No
portfolio other than the Strategic Fixed Income Portfolio will purchase
securities while borrowings (including reverse repurchase agreements) in excess
of 5% of its total assets are outstanding. No Portfolio other than Strategic
Fixed Income Portfolio has any intention of entering into reverse repurchase
agreements during the coming year.     
 
  WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. A security purchased on a when-
issued or delayed delivery basis is recorded as an asset on the commitment date
and is subject to changes in market value, generally based upon changes in the
level of interest rates. Thus, fluctuation in the value of the security from
the time of the commitment date will affect the Fund's net asset value. When a
Portfolio commits to purchase securities on a when-issued or delayed delivery
basis, its custodian segregates assets to cover the amount of the commitment.
See "Investment Policies and Limitations--Segregated Accounts." The Portfolios
purchase when-issued securities only with the intention of taking delivery, but
may sell the right to acquire the security prior to delivery if Mitchell
Hutchins or the applicable Sub-Adviser deems it advantageous to do so, which
may result in a capital gain or loss to a Portfolio.
   
  LENDING OF PORTFOLIO SECURITIES. As indicated in the Prospectus, the
Portfolios other than the Money Market Portfolio are authorized to lend their
portfolio securities. The Money Market Portfolio is authorized to lend up to
10% of the total value of its portfolio securities but has no intention of
doing so during the coming year. A Portfolio may lend its portfolio securities
to broker-dealers or institutional investors that Mitchell Hutchins or the
applicable Sub-Adviser deems qualified, but only when the borrower maintains
with the Portfolio's custodian bank collateral either in cash or money market
instruments, marked to market daily, in an amount at least equal to the market
value of the securities loaned, plus accrued interest and dividends. In
determining whether to lend securities to a particular broker-dealer or
institutional investor, Mitchell Hutchins or the applicable Sub-Adviser will
consider, and during the period of the loan will monitor, all relevant facts
and circumstances, including the creditworthiness of the borrower. The
Portfolios will retain authority to terminate any loans at any time. A
Portfolio may pay reasonable administrative and custodial fees in connection
with a loan and may pay a negotiated portion of the interest earned on the cash
or money market instruments held as collateral to the borrower or placing
broker. A Portfolio will receive reasonable interest on the loan or a flat fee
from the borrower and amounts equivalent to any dividends, interest or other
distributions on the securities loaned. A Portfolio will regain record
ownership of loaned securities to exercise beneficial rights, such as voting
and subscription rights and rights to dividends, interest or other
distributions, when regaining such rights is considered to be in the
Portfolio's interest.     
   
  SEGREGATED ACCOUNTS. When a Portfolio enters into certain transactions that
involve obligations to make future payments to third parties, including dollar
rolls, reverse repurchase agreements or the purchase of securities on a when-
issued or delayed delivery basis, the Portfolio will maintain with an approved
    
                                       8
<PAGE>
 
custodian in a segregated account cash, U.S. government securities or other
liquid high grade debt securities, marked to market daily, in an amount at
least equal to the Portfolio's obligation or commitment under such
transactions. As described below under "Hedging and Related Income Strategies,"
segregated accounts may also be required in connection with certain
transactions involving options or futures contracts, interest rate protection
transactions or forward currency contracts.
 
  CONCENTRATION. All Portfolios follow a policy not to make an investment in
any one industry if the investment would cause the aggregate value of the
Portfolio's investment in such industry to exceed 25% of the Portfolio's total
assets, except that this policy does not apply to obligations issued or
guaranteed by the U.S. government, its agencies or instrumentalities ("U.S.
government securities"), certificates of deposit and bankers' acceptances. This
is a fundamental policy and cannot be changed with respect to a Portfolio
without the affirmative vote of its shareholders. Under this policy as applied
to the Money Market Portfolio, gas, electric, water and telephone companies are
considered separate industries and, with respect to finance companies, the
following categories are considered separate industries: (a) captive automotive
finance; (b) captive equipment finance; (c) retail finance; (d) consumer loan;
and (e) diversified finance.
 
  INVESTMENT LIMITATIONS. Except as indicated otherwise, each Portfolio may
not:
 
    (1) purchase securities (except U.S. government securities) of any one
  issuer, if as a result at the time of purchase more than 5% of the
  Portfolio's total assets would be invested in such issuer, or the Portfolio
  would own or hold 10% or more of the outstanding voting securities of that
  issuer, except that 25% of the total assets of the Portfolio (50% in the
  case of the Global Income Portfolio) may be invested without regard to this
  limitation;
 
    (2) purchase securities on margin, except for short-term credit necessary
  for clearance of portfolio transactions and except that a Portfolio that
  may use options or futures strategies may make margin deposits in
  connection with its use of options, futures contracts and options on
  futures contracts;
 
    (3) mortgage, pledge, hypothecate or in any manner transfer, as security
  for indebtedness, any securities owned or held by the Portfolio, except as
  may be necessary in connection with permitted borrowings and then not in
  excess of 5% of the Portfolio's total assets taken at cost, provided that
  this does not prohibit escrow, collateral or margin arrangements in
  connection with the use of options, futures contracts and options on
  futures contracts by a Portfolio that may use options or futures
  strategies;
     
    (4) make short sales of securities or maintain a short position, except
  that a Portfolio that may use options or futures strategies may make short
  sales and may maintain short positions in connection with its use of
  options, futures contracts and options on futures contracts and the Growth
  and Income Portfolio may sell short "against the box";     
 
    (5) purchase or sell real estate, provided that a Portfolio may invest in
  securities secured by real estate or interests therein or issued by
  companies which invest in real estate or interests therein;
     
    (6) purchase or sell commodities or commodity contracts, except that a
  Portfolio that may use options or futures strategies may purchase or sell
  stock index futures and interest rate futures and options thereon and the
  Strategic Fixed Income, Global Income and Global Growth Portfolios may
  purchase or sell foreign currency futures and options thereon;     
 
    (7) invest in oil, gas or mineral-related programs or leases;
     
    (8) make loans, except through loans of portfolio securities of up to 10%
  of the value of the Portfolio's securities (33 1/3% for the Strategic Fixed
  Income Portfolio) and through repurchase agreements, provided that for
  purposes of this restriction the acquisition of bonds, debentures or other
  corporate debt securities and investment in government obligations, short-
  term commercial paper, certificates of deposit and bankers' acceptances
  shall not be deemed to be the making of a loan;     
 
    (9) purchase any securities issued by any other investment company except
  by purchase in the open market where no commission or profit, other than a
  customary broker's commission, is earned by any sponsor or dealer
  associated with the investment company whose shares are acquired as a
  result of such purchase, provided that such securities in the aggregate do
  not represent more than 10% of the total assets of the Portfolio, and
  except in connection with the merger, consolidation or acquisition of all
  the securities or assets of another investment company; or
 
                                       9
<PAGE>
 
     
    (10) (for Portfolios other than Strategic Fixed Income Portfolio) issue
  senior securities or borrow money, except from banks for temporary purposes
  and except for reverse repurchase agreements and provided that the
  aggregate amount of all such borrowing does not exceed 10% of the total
  asset value of the Portfolio at the time of such borrowing; provided
  further that the Portfolio will not purchase securities while borrowings
  (including reverse repurchase agreements) in excess of 5% of the total
  asset value of the Portfolio are outstanding.     
     
    (11) Strategic Fixed Income Portfolio may not issue senior securities or
  borrow money, except from banks or through reverse repurchase agreements
  and dollar rolls, and then in an aggregate amount not in excess of 33 1/3%
  of the Portfolio's total assets (including the amount of the borrowing but
  reduced by any liabilities not constituting senior securities) at the time
  of such borrowings; except that the Portfolio may borrow up to an
  additional 5% of its total assets (not including the amount borrowed) for
  temporary or emergency purposes.     
 
The foregoing fundamental investment limitations cannot be changed with respect
to a Portfolio without the affirmative vote of the lesser of (a) more than 50%
of the outstanding shares of the Portfolio or (b) 67% or more of the
Portfolio's shares present at a meeting of its shareholders if more than 50% of
the outstanding shares of the Portfolio are represented at the meeting in
person or by proxy. If a percentage restriction is adhered to at the time of an
investment or transaction, a later change in percentage resulting from a change
in values of portfolio securities or amount of total assets will not be
considered a violation of any of the foregoing limitations.
 
  The following investment restrictions may be changed by the vote of the
Fund's board of trustees without shareholder approval:
 
    (1) No Portfolio will hold assets of any issuers, at the end of any
  calendar quarter (or within 30 days thereafter), to the extent such
  holdings would cause the Portfolio to fail to comply with the
  diversification requirements imposed by section 817(h) of the Internal
  Revenue Code and the Treasury regulations issued thereunder on segregated
  asset accounts used to fund variable annuity contracts; and
 
    (2) Except under unusual circumstances, the Global Growth Portfolio will
  not purchase securities issued by investment companies unless they are
  issued by companies that follow a policy of investment primarily in the
  capital markets of a single foreign country.
 
                     HEDGING AND RELATED INCOME STRATEGIES
   
  As discussed in the Prospectus, Mitchell Hutchins or the applicable Sub-
Adviser may use a variety of financial instruments ("Hedging Instruments"),
including certain options, futures contracts (sometimes referred to as
"futures") and options on futures contracts, to attempt to hedge the
Portfolios' investments or attempt to enhance the Portfolios' income. For the
Strategic Fixed Income, Global Income and Global Growth Portfolios, Mitchell
Hutchins or the applicable Sub-Adviser also may use forward currency contracts,
foreign currency options and futures and options thereon. Strategic Fixed
Income and Global Income Portfolios also may enter into interest rate
protection transactions. The particular Hedging Instruments are described in
Appendix B to the Prospectus. The Money Market and Asset Allocation Portfolios
are not authorized to engage in hedging or related income strategies.     
 
  Hedging strategies can be broadly categorized as "short hedges" and "long
hedges." A short hedge is a purchase or sale of a Hedging Instrument intended
partially or fully to offset potential declines in the value of one or more
investments held by a Portfolio. Thus, in a short hedge a Portfolio takes a
position in a Hedging Instrument whose price is expected to move in the
opposite direction of the price of the investment being hedged. For example, a
Portfolio might purchase a put option on a security to hedge against a
potential decline in the value of that security. If the price of the security
declined below the exercise price of the put, the Portfolio could exercise the
put and thus limit its loss below the exercise price to the premium paid plus
transaction costs. In the alternative, because the value of the put option can
be expected to increase as the value of the underlying security declines, the
Portfolio might be able to close out the put option and realize a gain to
offset the decline in the value of the security.
 
                                       10
<PAGE>
 
  Conversely, a long hedge is a purchase or sale of a Hedging Instrument
intended partially or fully to offset potential increases in the acquisition
cost of one or more investments that a Portfolio intends to acquire. Thus, in a
long hedge a Portfolio takes a position in a Hedging Instrument whose price is
expected to move in the same direction as the price of the prospective
investment being hedged. For example, a Portfolio might purchase a call option
on a security it intends to purchase in order to hedge against an increase in
the cost of the security. If the price of the security increased above the
exercise price of the call, the Portfolio could exercise the call and thus
limit its acquisition cost to the exercise price plus the premium paid and
transaction costs. Alternatively, the Portfolio might be able to offset the
price increase by closing out an appreciated call option and realizing a gain.
   
  A Portfolio may purchase and write (sell) covered straddles on securities and
stock indices. A long straddle is a combination of a call and a put option
purchased on the same security or on the same futures contract, where the
exercise price of the put is less than or equal to the exercise price of the
call. A Portfolio might enter into a long straddle when Mitchell Hutchins or
the applicable Sub-Adviser believes it likely that interest rates will be more
volatile during the term of the option than the option pricing implies. A short
straddle is a combination of a call and a put written on the same security
where the exercise price of the put is less than or equal to the exercise price
of the call. A Portfolio might enter into a short straddle when Mitchell
Hutchins or the applicable Sub-Adviser believes it unlikely that interest rates
will be as volatile during the term of the option as the option pricing
implies.     
 
  Hedging Instruments on securities generally are used to hedge against price
movements in one or more particular securities positions that a Portfolio owns
or intends to acquire. Hedging Instruments on stock indices, in contrast,
generally are used to hedge against price movements in broad equity market
sectors in which the Portfolio has invested or expects to invest. Hedging
Instruments on debt securities may be used to hedge either individual
securities or broad fixed income market sectors.
 
  The use of Hedging Instruments is subject to applicable regulations of the
SEC, the several options and futures exchanges upon which they are traded, the
Commodity Futures Trading Commission ("CFTC") and various state regulatory
authorities. In addition, a Portfolio's ability to use Hedging Instruments will
be limited by tax considerations. See "Taxes."
   
  In addition to the products, strategies and risks described below and in the
Prospectus, Mitchell Hutchins or the applicable Sub-Adviser expects to discover
additional opportunities in connection with options, future contracts, forward
currency contracts and other hedging techniques. These new opportunities may
become available as Mitchell Hutchins or the applicable Sub-Adviser develops
new techniques, as regulatory authorities broaden the range of permitted
transactions and as new options, futures contracts, forward currency contracts
or other techniques are developed. Mitchell Hutchins or the applicable Sub-
Adviser may utilize these opportunities to the extent that they are consistent
with the Portfolios' investment objectives and permitted by the Portfolios'
investment limitations and applicable regulatory authorities. The Fund's
Prospectus or Statement of Additional Information will be supplemented to the
extent that new products or techniques involve materially different risks than
those described below or in the Prospectus.     
 
  SPECIAL RISKS OF HEDGING STRATEGIES. The use of Hedging Instruments involves
special considerations and risks, as described below. Risks pertaining to
particular Hedging Instruments are described in the sections that follow.
     
    (1) Successful use of most Hedging Instruments depends upon Mitchell
  Hutchins' or the applicable Sub-Adviser's ability to predict movements of
  the overall securities, currency and interest rate markets, which requires
  different skills than predicting changes in the prices of individual
  securities. While Mitchell Hutchins or the applicable Sub-Adviser is
  experienced in the use of Hedging Instruments, there can be no assurance
  that any particular hedging strategy adopted will succeed.     
 
                                       11
<PAGE>
 
    (2) There might be imperfect correlation, or even no correlation, between
  price movements of a Hedging Instrument and price movements of the
  investments being hedged. For example, if the value of a Hedging Instrument
  used in a short hedge increased by less than the decline in value of the
  hedged investment, the hedge would not be fully successful. Such a lack of
  correlation might occur due to factors unrelated to the value of the
  investments being hedged, such as speculative or other pressures on the
  markets in which Hedging Instruments are traded. The effectiveness of
  hedges using Hedging Instruments or indices will depend on the degree of
  correlation between price movements in the index and price movements in the
  securities being hedged.
     
    (3) Hedging strategies, if successful, can reduce risk of loss by wholly
  or partially offsetting the negative effect of unfavorable price movements
  in the investments being hedged. However, hedging strategies can also
  reduce opportunity for gain by offsetting the positive effect of favorable
  price movements in the hedged investments. For example, if a Portfolio
  entered into a short hedge because Mitchell Hutchins or the applicable Sub-
  Adviser projected a decline in the price of a security held by a Portfolio,
  and the price of that security increased instead, the gain from that
  increase might be wholly or partially offset by a decline in the price of
  the Hedging Instrument. Moreover, if the price of the Hedging Instrument
  declined by more than the increase in the price of the security, the
  Portfolio could suffer a loss. In either such case, the Portfolio would
  have been in a better position had it not hedged at all.     
 
    (4) As described below, a Portfolio might be required to maintain assets
  as "cover," maintain segregated accounts or make margin payments when it
  takes positions in Hedging Instruments involving obligations to third
  parties (i.e., Hedging Instruments other than purchased options). If a
  Portfolio were unable to close out its positions in such Hedging
  Instruments, it might be required to continue to maintain such assets or
  accounts or make such payments until the position expired or matured. These
  requirements might impair a Portfolio's ability to sell a portfolio
  security or make an investment at a time when it would otherwise be
  favorable to do so, or require that a Portfolio sell a portfolio security
  at a disadvantageous time. A Portfolio's ability to close out a position in
  a Hedging Instrument prior to expiration or maturity depends on the
  existence of a liquid secondary market or, in the absence of such a market,
  the ability and willingness of a contra party to enter into a transaction
  closing out the position. Therefore, there is no assurance that any hedging
  position can be closed out at a time and price that is favorable to the
  Portfolio.
 
  COVER FOR HEDGING STRATEGIES. Transactions using Hedging Instruments, other
than purchased options, expose a Portfolio to an obligation to another party.
A Portfolio will not enter into any such transactions unless it owns either
(1) an offsetting ("covered") position in securities, currencies or other
options, futures contracts or forward currency contracts or (2) cash and
short-term liquid debt securities, with a value sufficient at all times to
cover its potential obligations to the extent not covered as provided in (1)
above. Each Portfolio will comply with SEC guidelines regarding cover for
hedging transactions and will, if the guidelines so require, set aside cash,
U.S. government securities or other liquid, high-grade debt securities in a
segregated account with its custodian in the prescribed amount.
 
  Assets used as cover or held in a segregated account cannot be sold while
the position in the corresponding Hedging Instrument is open, unless they are
replaced with similar assets. As a result, the commitment of a large portion
of a Portfolio's assets to cover or segregated accounts could impede portfolio
management or the Portfolio's ability to meet redemption requests or other
current obligations.
   
  OPTIONS. Each Portfolio that may use options may purchase put and call
options, and write (sell) covered put and call options on equity and debt
securities and, in the case of Strategic Fixed Income, Global Income and
Global Growth Portfolios, on foreign currencies. Each Portfolio that may use
options may purchase put and call options and write (sell) covered call
options on stock indices. The purchase of call options serves as a long hedge,
and the purchase of put options serves as a short hedge. Writing covered put
or call options can enable a Portfolio to enhance income by reason of the
premiums paid by the purchasers of     
 
                                      12
<PAGE>
 
such options. Writing covered put options serves as a limited long hedge
because increases in the value of the hedged instrument would be offset to the
extent of the premium received for writing the option. However, if the market
price of the security underlying a covered put option declines to less than the
exercise price of the option, minus the premium received, the Portfolio would
expect to suffer a loss. Writing covered call options serves as a limited short
hedge, because declines in the value of the hedged investment would be offset
to the extent of the premium received for writing the option. However, if the
security appreciates to a price higher than the exercise price of the call
option, it can be expected that the option will be exercised and the Portfolio
will be obligated to sell the security at less than its market value. The
securities or other assets used as cover for OTC options written by a Portfolio
would be considered illiquid to the extent described under "Investment Policies
and Restrictions--Illiquid Securities."
 
  The value of an option position will reflect, among other things, the current
market value of the underlying investment, the time remaining until expiration,
the relationship of the exercise price to the market price of the underlying
investment, the historical price volatility of the underlying investment and
general market conditions. Options normally have expiration dates of up to nine
months. Options that expire unexercised have no value.
 
  A Portfolio may effectively terminate its right or obligation under an option
by entering into a closing transaction. For example, a Portfolio may terminate
its obligation under a call option that it had written by purchasing an
identical call option; this is known as a closing purchase transaction.
Conversely, a Portfolio may terminate a position in a put or call option it had
purchased by writing an identical put or call option; this is known as a
closing sale transaction.
 
  The Portfolios may purchase or write both exchange-traded and OTC options.
Currently, many options on equity securities are exchange-traded. Exchange
markets for options on debt securities and foreign currencies exist but are
relatively new, and these instruments are primarily traded on the OTC market.
Exchange-traded options in the United States are issued by a clearing
organization affiliated with the exchange on which the option is listed which,
in effect, guarantees completion of every exchange-traded option transaction.
In contrast, OTC options are contracts between the Portfolio and its contra
party (usually a securities dealer or a bank) with no clearing organization
guarantee. Thus, when the Portfolio purchases or writes an OTC option, it
relies on the contra party to make or take delivery of the underlying
investment upon exercise of the option. Failure by the contra party to do so
would result in the loss of any premium paid by the Portfolio as well as the
loss of any expected benefits of the transaction. A Portfolio will enter into
OTC option transactions only with contra parties that have a net worth of at
least $20 million.
 
  Generally, the OTC debt and foreign currency options used by the Portfolios
are European-style options. This means that the option is only exercisable
immediately prior to its expiration. This is in contrast to American-style
options, which are exercisable at any time prior to the expiration date of the
option.
 
  A Portfolio's ability to establish and close out positions in exchange-listed
options depends on the existence of a liquid market. Each Portfolio intends to
purchase or write only those exchange-traded options for which there appears to
be a liquid secondary market. However, there can be no assurance that such a
market will exist at any particular time. Closing transactions can be made for
OTC options only by negotiating directly with the contra party, or by a
transaction in the secondary market if any such market exists. Although a
Portfolio will enter into OTC options only with contra parties that are
expected to be capable of entering into closing transactions with the
Portfolio, there is no assurance that the Portfolio will in fact be able to
close out an OTC option position at a favorable price prior to expiration. In
the event of insolvency of the contra party, the Portfolio might be unable to
close out an OTC option position at any time prior to its expiration.
 
  If the Portfolio were unable to effect a closing transaction for an option it
had purchased, it would have to exercise the option to realize any profit. The
inability to enter into a closing purchase transaction for a covered call
option written by a Portfolio could cause material losses because the Portfolio
would be unable to sell the investment used as cover for the written option
until the option expires or is exercised.

  LIMITATIONS ON THE USE OF OPTIONS. The Portfolios' use of options is
governed by the following guidelines, which can be changed by the Fund's board
of trustees without shareholder vote:
 
    (1) a Portfolio may purchase a put or call option, including any
  straddles or spreads, only if the value of its premium, when aggregated
  with the premiums on all other options held by the Portfolio, does not
  exceed 5% of the Portfolio's total assets.
 
    (2) The aggregate value of securities underlying put options written by a
  Portfolio, determined as of the date the put options are written, will not
  exceed 50% of the Portfolio's net assets.
 
    (3) The aggregate premiums paid on all options (including options on
  securities, foreign currencies and stock or bond indices and options on
  futures contracts) purchased by a Portfolio that are held at any time will
  not exceed 20% of the Portfolio's net assets.
 
  FUTURES. The purchase of futures or call options thereon can serve as a long
hedge, and the sale of futures or the purchase of put options thereon can
serve as a short hedge. Writing covered call options on futures contracts can
serve as a limited short hedge, using a strategy similar to that used for
writing covered call options on securities and indices.
 
  Futures strategies also can be used to manage the average duration of a
Portfolio. If Mitchell Hutchins wishes to shorten the average duration of a
Portfolio, the Portfolio may sell a futures contract or a call option thereon,
or purchase a put option on that futures contract. If Mitchell Hutchins wishes
to lengthen the average duration of a Portfolio, the Portfolio may buy a
futures contract or a call option thereon.
   
  The Strategic Fixed Income Global Income and Global Growth Portfolios may
also write put options on foreign currency futures contracts while at the same
time purchasing call options on the same futures contracts in order
synthetically to create a long futures contract position. Such options would
have the same strike prices and expiration dates. Each Portfolio will engage
in this strategy only when it is more advantageous to the Portfolio than is
purchasing the futures contract.     
 
  No price is paid upon entering into a futures contract. Instead, at the
inception of a futures contract a Portfolio is required to deposit in a
segregated account with its custodian, in the name of the futures broker
through whom the transaction was effected, "initial margin" consisting of
cash, U.S. government securities or other liquid, high-grade debt securities,
in an amount generally equal to 10% or less of the contract value. Margin must
also be deposited when writing an option on a futures contract, in accordance
with applicable exchange rules. Unlike margin in securities transactions,
initial margin on futures contracts does not represent a borrowing, but rather
is in the nature of a performance bond or good-faith deposit that is returned
to the Portfolio at the termination of the transaction if all contractual
obligations have been satisfied. Under certain circumstances, such as periods
of high volatility, the Portfolio may be required by an exchange to increase
the level of its initial margin payment, and initial margin requirements might
be increased generally in the future by regulatory action.
 
  Subsequent "variation margin" payments are made to and from the futures
broker daily as the value of the futures position varies, a process known as
"marking to market." Variation margin does not involve borrowing, but rather
represents a daily settlement of the Portfolio's obligations to or from a
futures broker. When a Portfolio purchases an option on a future, the premium
paid plus transaction costs is all that is at risk. In contrast, when a
Portfolio purchases or sells a futures contract or writes a call option
thereon, it is subject to daily variation margin calls that could be
substantial in the event of adverse price movements. If the Portfolio has
insufficient cash to meet daily variation margin requirements, it might need
to sell securities at a time when such sales are disadvantageous.
 
  Holders and writers of futures positions and options on futures can enter
into offsetting closing transactions, similar to closing transactions on
options, by selling or purchasing, respectively, an instrument identical to
the instrument held or written. Positions in futures and options on futures
may be closed only on an exchange or board of trade that provides a secondary
market. Each Portfolio intends to enter into futures transactions only on
exchanges or boards of trade where there appears to be a liquid secondary
market. However, there can be no assurance that such a market will exist for a
particular contract at a particular time.
 
                                      14
<PAGE>
 
  Under certain circumstances, futures exchanges may establish daily limits on
the amount that the price of a future or related option can vary from the
previous day's settlement price; once that limit is reached, no trades may be
made that day at a price beyond the limit. Daily price limits do not limit
potential losses because prices could move to the daily limit for several
consecutive days with little or no trading, thereby preventing liquidation of
unfavorable positions.
 
  If a Portfolio were unable to liquidate a futures or related options position
due to the absence of a liquid secondary market or the imposition of price
limits, it could incur substantial losses. The Portfolio would continue to be
subject to market risk with respect to the position. In addition, except in the
case of purchased options, the Portfolio would continue to be required to make
daily variation margin payments and might be required to maintain the position
being hedged by the future or option or to maintain cash or securities in a
segregated account.
 
  Certain characteristics of the futures market might increase the risk that
movements in the prices of futures contracts or related options might not
correlate perfectly with movements in the prices of the investments being
hedged. For example, all participants in the futures and related options
markets are subject to daily variation margin calls and might be compelled to
liquidate futures or related options positions whose prices are moving
unfavorably to avoid being subject to further calls. These liquidations could
increase price volatility of the instruments and distort the normal price
relationship between the futures or options and the investments being hedged.
Also, because initial margin deposit requirements in the futures market are
less onerous than margin requirements in the securities markets, there might be
increased participation by speculators in the futures markets. This
participation also might cause temporary price distortions. In addition,
activities of large traders in both the futures and securities markets
involving arbitrage, "program trading" and other investment strategies might
result in temporary price distortions.
 
  LIMITATIONS ON THE USE OF FUTURES. The Portfolios' use of futures is governed
by the following guidelines, which can be changed by the Fund's board of
trustees without shareholder vote.
 
    (1) To the extent a Portfolio enters into futures contracts, options on
  futures positions and options on foreign currencies trade on a commodities
  exchange that are not for bona fide hedging purposes (as defined by the
  CFTC), the aggregate initial margin and premiums on those positions
  (excluding the amount by which options are "in-the-money") may not exceed
  5% of the Portfolio's net assets.
 
    (2) The aggregate premiums on all options (including options on
  securities, foreign currencies and stock or bond indices and options on
  futures contracts) purchased by a Portfolio that are held at any time will
  not exceed 20% of the Portfolio's net assets.
 
    (3) The aggregate margin deposits on all futures contracts and options
  thereon held at any time by a Portfolio will not exceed 5% of the
  Portfolio's total assets.
   
  FOREIGN CURRENCY HEDGING STRATEGIES--SPECIAL CONSIDERATIONS. The Strategic
Fixed Income, Global Income and Global Growth Portfolios may use options and
futures on foreign currencies, as described above, and forward currency forward
contracts, as described below, to hedge against movements in the values of the
foreign currencies in which the Portfolios' securities are denominated. Such
currency hedges can protect against price movements in a security that a
Portfolio owns or intends to acquire that are attributable to changes in the
value of the currency in which it is denominated. Such hedges do not, however,
protect against price movements in the securities that are attributable to
other causes.     
   
  The Portfolios might seek to hedge against changes in the value of a
particular currency when no Hedging Instruments on that currency are available
or such Hedging Instruments are more expensive than certain other Hedging
Instruments. In such cases, a Portfolio may hedge against price movements in
that currency by entering into transactions using Hedging Instruments on
another foreign currency or a basket of currencies, the values of which
Mitchell Hutchins or the applicable Sub-Adviser believes will have a high
degree of positive correlation to the value of the currency being hedged. The
risk that movements in the price of the Hedging Instrument will not correlate
perfectly with movements in the price of the currency being hedged is magnified
when this strategy is used.     
 
                                       15
<PAGE>
 
  The value of Hedging Instruments on foreign currencies depends on the value
of the underlying currency relative to the U.S. dollar. Because foreign
currency transactions occurring in the interbank market might involve
substantially larger amounts than those involved in the use of such Hedging
Instruments, the Portfolios could be disadvantaged by having to deal in the 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 generally is representative of very large transactions in the
interbank market and thus might not reflect odd-lot transactions where rates
might be less favorable. The interbank market in foreign currencies is a
global, round-the-clock market. To the extent the U.S. options or futures
markets are closed while the markets for the underlying currencies remain open,
significant price and rate movements might take place in the underlying markets
that cannot be reflected in the markets for the Hedging Instruments until they
reopen.
 
  Settlement of hedging transactions involving foreign currencies might be
required to take place within the country issuing the underlying currency.
Thus, a Portfolio might be required to accept or make delivery of the
underlying foreign currency in accordance with any U.S. or foreign regulations
regarding the maintenance of foreign banking arrangements by U.S. residents and
might be required to pay any fees, taxes and charges associated with such
delivery assessed in the issuing country.
   
  FORWARD CURRENCY CONTRACTS. The Strategic Fixed Income, Global Income and
Global Growth Portfolios may enter into forward currency contracts to purchase
or sell foreign currencies for a fixed amount of U.S. dollars or another
foreign currency. Such transactions may serve as long hedges--for example, a
Portfolio may purchase a forward currency contract to lock in the U.S. dollar
price of a security denominated in a foreign currency that the Portfolio
intends to acquire. Forward currency contract transactions may also serve as
short hedges--for example, a Portfolio may sell a forward currency contract to
lock in the U.S. dollar equivalent of the proceeds from the anticipated sale of
a security denominated in a foreign currency.     
   
  As noted above, these Portfolios may seek to hedge against changes in the
value of a particular currency by using forward contracts on another foreign
currency or a basket of currencies, the value of which Mitchell Hutchins or the
applicable Sub-Adviser believes will have a positive correlation to the values
of the currency being hedged. In addition, the Portfolios may use forward
currency contracts to shift exposure to foreign currency fluctuations from one
country to another. For example, if a Portfolio owns securities denominated in
a foreign currency and Mitchell Hutchins or the applicable Sub-Adviser believes
that currency will decline relative to another currency, it might enter into a
forward contract to sell an appropriate amount of the first foreign currency,
with payment to be made in the second foreign currency. Transactions that use
two foreign currencies are sometimes referred to as "cross hedging." Use of a
different foreign currency magnifies the risk that movements in the price of
the Hedging Instrument will not correlate or will correlate unfavorably with
the foreign currency being hedged.     
 
  The cost to the Portfolios engaging in forward currency contracts varies with
factors such as the currency involved, the length of the contract period and
the market conditions then prevailing. Because forward currency contracts are
usually entered into on a principal basis, no fees or commissions are involved.
When a Portfolio enters into a forward currency contract, it relies on the
contra party to make or take delivery of the underlying currency at the
maturity of the contract. Failure by the contra party to do so would result in
the loss of any expected benefit of the transaction.
 
  As is the case with future contracts, holders and writers of forward currency
contracts can enter into offsetting closing transactions, similar to closing
transactions on futures, by selling or purchasing, respectively, an instrument
identical to the instrument held or written. Secondary markets generally do not
 
                                       16
<PAGE>
 
exist for forward currency contracts, with the result that closing transactions
generally can be made for forward currency contracts only by negotiating
directly with the contra party. Thus, there can be no assurance that a
Portfolio will in fact be able to close out a forward currency contract at a
favorable price prior to maturity. In addition, in the event of insolvency of
the contra party, the Portfolio might be unable to close out a forward currency
contract at any time prior to maturity. In either event, the Portfolio would
continue to be subject to market risk with respect to the position, and would
continue to be required to maintain a position in securities denominated in the
securities or currencies that are the subject of the hedge or to maintain cash
or securities in a segregated account.
 
  The precise matching of forward currency contract amounts and the value of
the securities involved generally will not be possible because the value of
such securities, measured in the foreign currency, will change after the
foreign currency contract has been established. Thus, a Portfolio might need to
purchase or sell foreign currencies in the spot (cash) market to the extent
such foreign currencies are not covered by forward contracts. The projection of
short-term currency market movements is extremely difficult, and the successful
execution of a short-term hedging strategy is highly uncertain.
   
  LIMITATIONS ON THE USE OF FORWARD CURRENCY CONTRACTS. The Strategic Fixed
Income, Global Income and Global Growth Portfolios may enter into forward
currency contracts or maintain a net exposure to such contracts only if (1) the
consummation of the contracts would not obligate the Portfolio to deliver an
amount of foreign currency in excess of the value of the position being hedged
by such contracts or (2) the Portfolio maintains appropriate assets in a
segregated account in an amount not less than the value of its total assets
committed to the consummation of the contract and not covered as provided in
(1) above, as described above in "Investment Policies and Limitations--
Segregated Accounts."     
   
  INTEREST RATE PROTECTION TRANSACTIONS. The Strategic Fixed Income and Global
Income Portfolios may enter into interest rate protection transactions,
including interest rate swaps and interest rate caps, collars and floors.
Interest rate swap transactions involve an agreement between two parties to
exchange payments that are based, for example, on variable and fixed rates of
interest and that are calculated on the basis of a specified amount of
principal (the "notional principal amount") for a specified period of time.
Interest rate cap and floor transactions involve an agreement between two
parties in which the first party agrees to make payments to the counterparty
when a designated market interest rate goes above (in the case of a cap) or
below (in the case of a floor) a designated level on predetermined dates or
during a specified time period. Interest rate collar transactions involve an
agreement between two parties in which payments are made when a designated
market interest rate either goes above a designated ceiling level or goes below
a designated floor level on predetermined dates or during a specified time
period.     
   
  Strategic Fixed Income and Global Income Portfolios each expect to enter into
interest rate protection transactions to preserve a return or spread on a
particular investment or portion of its portfolio or to protect against any
increase in the price of securities it anticipates purchasing at a later date.
The Portfolios intend to use these transactions as a hedge and not as a
speculative investment. Interest rate protection transactions are subject to
risks comparable to those described above with respect to other hedging
strategies.     
   
  Strategic Fixed Income and Global Income Portfolios each may enter into
interest rate swaps, caps, collars and floors on either an asset-based or
liability-based basis, depending on whether it is hedging its assets or its
liabilities, and will usually enter into interest rate swaps on a net basis,
i.e., the two payment streams are netted out, with the Portfolio receiving or
paying, as the case may be, only the net amount of the two payments. Inasmuch
as these interest rate protection transactions are entered into for good faith
hedging purposes, and inasmuch as segregated accounts will be established with
respect to such transactions, Mitchell Hutchins and the Portfolio believe such
obligations do not constitute senior securities and, accordingly, will not
treat them as being subject to the Portfolio's borrowing restrictions. The net
amount of the excess, if any, of a Portfolio's obligations over its
entitlements with respect to each interest rate swap will be accrued on a daily
basis and appropriate Portfolio assets having an aggregate net asset value at
least equal to the accrued     
 
                                       17
<PAGE>
 
   
excess will be maintained in a segregated account, as described above in
"Investment Policies and Limitations--Segregated Accounts." Each Portfolio also
will establish and maintain such segregated accounts with respect to its total
obligations under any interest rate swaps that are not entered into on a net
basis and with respect to any interest rate caps, collars and floors that are
written by the Portfolio.     
   
  Strategic Fixed Income and Global Income Portfolios each will enter into
interest rate protection transactions only with banks and recognized securities
dealers believed by Mitchell Hutchins to present minimal credit risks in
accordance with guidelines established by the Fund's board of trustees. If
there is a default by the other party to such a transaction, the Portfolio will
have to rely on its contractual remedies (which may be limited by bankruptcy,
insolvency or similar laws) pursuant to the agreements related to the
transaction.     
 
  The swap market has grown substantially in recent years with a large number
of banks and investment banking firms acting both as principals and as agents
utilizing standardized swap documentation. Caps, collars and floors are more
recent innovations for which documentation is less standardized, and,
accordingly, they are less liquid than swaps.

  Under the Advisory Contract, Mitchell Hutchins will not be liable for any
error of judgment or mistake of law or for any loss suffered by the Fund in
connection with the performance of the Advisory Contract, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part
of Mitchell Hutchins in the performance of its duties or from reckless
disregard of its duties and obligations thereunder. Under each Sub-Advisory
Contract, the Sub-Adviser will not be liable for any error of judgment or
mistake of law or for any loss suffered by the Fund, the Portfolio, its
shareholders or Mitchell Hutchins in connection with the Sub-Advisory Contract,
except any liability to the Fund, the Portfolio, its shareholders or Mitchell
Hutchins to which the Sub-Adviser would otherwise be subject by reason of
willful misfeasance, bad faith, gross negligence on its part in the performance
of its duties or from reckless disregard by it of its obligations and duties
under the Sub-Advisory contract.     
   
  The Advisory Contract terminates automatically upon assignment and is
terminable at any time without penalty by the Fund's board of trustees or by
vote of the holders of a majority of the Portfolio's outstanding voting
securities on 60 days' written notice to Mitchell Hutchins or by Mitchell
Hutchins on 60 days' written notice to the Fund. Each Sub-Advisory Contract
terminates automatically upon its assignment or the termination of the Advisory
Contract and is terminable at any time without penalty by the board of trustees
or by vote of the holders of a majority of the Portfolio's outstanding voting
securities on 60 days' notice to the Sub-Adviser, or by the Sub-Adviser on 120
days' written notice to Mitchell Hutchins. The Sub-Advisory Contract may also
be terminated by Mitchell Hutchins (1) upon material breach by the Sub-Adviser
of its representations and warranties; (2) if the Sub-Adviser becomes unable to
discharge its duties and obligations under the Sub-Advisory contract or (3) on
120 days' notice to the Sub-Adviser.

                            PORTFOLIO TRANSACTIONS
   
  Subject to policies established by the Fund's board of trustees, Mitchell
Hutchins or the applicable Sub-Adviser is responsible for the execution of
portfolio transactions and the allocation of brokerage transactions for each
Portfolio. In executing portfolio transactions, Mitchell Hutchins or the
applicable Sub-Adviser seeks to obtain the best net results for each Portfolio
taking into account such factors as the price (including the applicable
brokerage commission or dealer spread), size of the order, difficulty of
execution and operational facilities of the firm involved. Prices paid to
dealers in principal transactions through which most debt securities and some
equity securities are traded generally include a "spread," which is the
difference between the prices at which the dealer is willing to purchase and
sell a specific security at that time. Each Portfolio may invest in securities
traded in the OTC markets and will engage primarily in transactions with the
dealers who make markets in such securities, unless a better price or
execution could be obtained by using a broker. While Mitchell Hutchins or the
applicable Sub-Adviser generally seeks reasonably competitive commission
rates, payment of the lowest commission is not necessarily consistent with
obtaining the best net results. During the fiscal year ended December 31,
1992, the Money Market, Strategic Fixed Income and Global Income Portfolios
paid no commissions, while the Asset Allocation, Growth and Income, Growth,
and Global Growth Portfolios paid aggregate commissions totalling $40,643,
$34,551, $281,467, and $44,608, respectively. During the fiscal year ended
December 31, 1993, the Money Market, Strategic Fixed Income, and Global Income
Portfolios paid no commissions, while the Asset Allocation, Growth and Income,
Growth and Global Growth Portfolios paid aggregate commissions totalling
$74,851, $32,158, $32,332 and $442,008, respectively. During the fiscal year
ended December 31, 1994, the Money Market, Strategic Fixed Income, and Global
Income Portfolios paid no commissions, while the Asset Allocation, Growth and
Income, Growth, and Global Growth Portfolios paid aggregate commissions
totalling $63,641, $45,863, $37,100, and $397,060, respectively.     
   
  The Fund has no obligation to deal with any broker or group of brokers in
the execution of portfolio transactions. The Fund contemplates that,
consistent with the policy of obtaining the best net results, a substantial
amount of the Portfolios' brokerage transactions may be conducted through
Mitchell Hutchins or its affiliates, including PaineWebber. The Fund's board
of trustees has adopted procedures in conformity with Rule 17e-1 under the
1940 Act to ensure that all brokerage commissions paid to Mitchell Hutchins or
its affiliates are fair and reasonable. Specific provisions included in the
Advisory Contract authorize Mitchell Hutchins and any of its affiliates that
is a member of a national securities exchange to effect securities
transactions for the Portfolios on such exchange and to retain compensation in
connection with such transactions. Any such transactions will be effected and
related compensation paid in accordance with applicable SEC regulations.
During the fiscal year ended December 31, 1992, Asset Allocation Portfolio
paid $420, Growth and Income Portfolio paid $966 and Growth Portfolio paid
$1,509 in brokerage commissions to PaineWebber. During the fiscal year ended
December 31, 1993, Asset Allocation Portfolio paid $1,274, Growth and Income
Portfolio paid $2,283 and Growth Portfolio paid $595 in brokerage commissions
to PaineWebber. During the fiscal year ended December 31, 1994, Asset
Allocation Portfolio paid $720 in brokerage commissions to PaineWebber,
representing 1.13% of the aggregate brokerage commissions paid by that
Portfolio and 1.61% of the aggregate dollar amount of transactions involving
the payment of commissions. During the fiscal year ended December 31, 1994,
Growth and Income Portfolio paid $1,817 in commissions to PaineWebber,
representing 3.96% of the aggregate brokerage commissions paid by that
Portfolio and 5.2% of the aggregate dollar amount of transactions involving
the payment of commissions. During the fiscal year ended December 31, 1994,
Growth Portfolio paid $600 in brokerage commissions to PaineWebber,
representing 1.61% of the aggregate brokerage commissions paid by that
Portfolio and 1.03% of the aggregate dollar amount of transactions involving
the payment of commissions. During the fiscal year ended December 31, 1994,
Global Growth Portfolio paid $1,137 in brokerage commissions to PaineWebber,
representing 0.01% of the aggregate brokerage commissions paid by the
Portfolio and 0.01% of the aggregate dollar amount of transactions involving
the payment of commissions. The other Portfolios did not pay any brokerage
commissions to PaineWebber or any other affiliate of Mitchell Hutchins during
the last three fiscal years.     
 
                                      24

  Transactions in futures contracts are executed through futures commission
merchants ("FCMs") who receive brokerage commissions for their services. The
Fund's procedures in selecting FCMs to execute the Portfolios' transactions in
futures contracts, including procedures permitting the use of Mitchell Hutchins
and its affiliates, are similar to those in effect with respect to brokerage
transactions in securities.
   
  Consistent with the interest of each Portfolio and subject to the review of
the Fund's board of trustees, Mitchell Hutchins or the applicable Sub-Adviser
may cause a Portfolio to purchase and sell portfolio securities from and to
brokers who provide the Portfolio with research, analysis, advice and similar
services. In return for such services, the Portfolio may pay to those brokers a
higher commission than may be charged by other brokers, provided that Mitchell
Hutchins or the applicable Sub-Adviser determines in good faith that such
commission is reasonable in terms either of that particular transaction or of
the overall responsibility of Mitchell Hutchins or the applicable Sub-Adviser
to the Portfolio and its other clients and that the total commissions paid by
the Portfolio will be reasonable in relation to the benefits to the Portfolio
over the long term. During the fiscal year ended December 31, 1994, the Asset
Allocation, Growth and Income, Growth and Global Growth Portfolios directed
$5,868,328, $6,851,516, $1,631,799 and $4,817,215, respectively, in portfolio
transactions to brokers chosen because they provide research and analysis for
which these Portfolios paid $9,241, $8,767, $1,890 and $21,912, respectively,
in commissions. During the same period, no other Portfolio paid any brokerage
commissions to brokers chosen because they provide research and analysis.     
   
  For purchases or sales with broker-dealer firms which act as principal,
Mitchell Hutchins or the applicable Sub-Adviser seeks best execution. Although
Mitchell Hutchins may receive certain research or execution services in
connection with these transactions. Mitchell Hutchins or the applicable Sub-
Adviser will not purchase securities at a higher price or sell securities at a
lower price than would otherwise be paid if no weight was attributed to the
services provided by the executing dealer. Moreover, Mitchell Hutchins or the
applicable Sub-Adviser will not enter into any explicit soft dollar
arrangements relating to principal transactions and will not receive in
principal transactions the types of services which could be purchased for hard
dollars. Mitchell Hutchins or the applicable Sub-Adviser may engage in agency
transactions in OTC equity and debt securities in return for research and
execution services. These transactions are entered into only in compliance with
procedures ensuring that the transaction (including commissions) is at least as
favorable as it would have been if effected directly with a market-maker that
did not provide research or execution services. These procedures include
Mitchell Hutchins or the applicable Sub-Adviser receiving multiple quotes from
dealers before executing the transaction on any agency basis.     
   
  Information and research received from such brokers and dealers will be in
addition to, and not in lieu of, the services required to be performed by
Mitchell Hutchins or the applicable Sub-Adviser under the Advisory Contract or
Sub-Advisory Contract. Research services furnished by brokers or dealers
through which or with which the Portfolios effect securities transactions may
be used by Mitchell Hutchins or the applicable Sub-Adviser in advising other
funds or accounts and, conversely, research services furnished to Mitchell
Hutchins or the applicable Sub-Adviser in connection with these other funds or
accounts may be used in advising the Portfolios.     
   
  Investment decisions for each Portfolio and for other investment accounts
managed by Mitchell Hutchins or the applicable Sub-Adviser are made
independently of each other in light of differing considerations for the
various accounts. However, the same investment decision may occasionally be
made for a Portfolio and one or more of such accounts. In such cases,
simultaneous transactions are inevitable. Purchases or sales are then averaged
as to price and allocated between the Portfolio and such other account(s) as to
amount according to a formula deemed equitable to the Portfolio and such
account(s). While in some cases this practice could have a detrimental effect
upon the price or value of the security as far as a Portfolio is concerned, or
upon its ability to complete its entire order, in other cases it is believed
that coordination and the ability to participate in volume transactions will be
beneficial to the Portfolio.     
 
                                       25
<PAGE>
 
   
  The Portfolios will not purchase securities that are offered in underwritings
in which Mitchell Hutchins, the applicable Sub-Adviser or any of its affiliates
is a member of the underwriting or selling group, except pursuant to procedures
adopted by the Fund's board of trustees pursuant to Rule 10f-3 under the 1940
Act. Among other things, these procedures require that the commission or spread
paid in connection with such a purchase be reasonable and fair, that the
purchase be at not more than the public offering price prior to the end of the
first business day after the date of the public offering and that Mitchell
Hutchins, the applicable Sub-Adviser or any affiliate thereof not participate
in or benefit from the sale to the Fund.     
   
  PORTFOLIO TURNOVER. The turnover rate may vary greatly from year to year for
any Portfolio and will not be a limiting factor when Mitchell Hutchins or the
applicable Sub-Adviser deems portfolio changes appropriate. The annual
portfolio turnover rate is calculated by dividing the lesser of a Portfolio's
annual sales or purchases of portfolio securities (exclusive of purchases or
sales of securities whose maturities at the time of acquisition were one year
or less) by the monthly average value of the securities except short-term
securities in the Portfolio during the year. For the fiscal years ended
December 31, 1994 and December 31, 1993, respectively, the portfolio turnover
rates were 53.72% and 7.93% for the Strategic Fixed Income Portfolio, 97.40%
and 68.60% for the Global Income Portfolio, 112.32% and 60.36% for the Asset
Allocation Portfolio, 27.35% and 34.95% for the Growth Portfolio, 175.34% and
266.96% for the Global Growth Portfolio and 149.68% and 51.68% for the Growth
and Income Portfolio.     
 
                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION
 
  The insurance company separate accounts purchase and redeem shares of each
Portfolio on each day on which the New York Stock Exchange, Inc. ("NYSE") is
open for trading ("Business Day") based on, among other things, the amount of
premium payments to be invested and surrendered and transfer requests to be
effected on that day pursuant to the variable contracts. Currently, the NYSE is
closed on the observance of New Year's Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
Such purchases and redemptions of the shares of each Portfolio are effected at
their respective net asset values per share determined as of the close of
trading (currently 4:00 p.m., eastern time) on that Business Day. Payment for
redemptions are made by the Fund within seven days thereafter. No fee is
charged the separate accounts when they purchase or redeem Portfolio shares.
 
  The Fund may suspend redemption privileges of shares of any Portfolio or
postpone the date of payment during any period (1) when the NYSE is closed or
trading on the NYSE is restricted as determined by the SEC, (2) when an
emergency exists, as defined by the SEC, that makes it not reasonably
practicable for the Fund to dispose of securities owned by it or fairly to
determine the value of its assets or (3) as the SEC may otherwise permit. The
redemption price may be more or less than the shareholder's cost, depending on
the market value of the Portfolio's securities at the time.
 
                              VALUATION OF SHARES
 
  Each Portfolio determines its net asset value as of the close of regular
trading (currently 4:00 p.m., eastern time) on the NYSE on each Monday through
Friday when the NYSE is open.
   
  Securities that are listed on U.S. and foreign stock exchanges are valued at
the last sale price on the day the securities are being valued or, lacking any
sales on such day, at the last available bid price. In cases where securities
are traded on more than one exchange, the securities are generally valued on
the exchange considered by Mitchell Hutchins or the applicable Sub-Adviser as
the primary market. Securities traded in the OTC market and listed on the
Nasdaq are valued at the last available sale price listed on Nasdaq at 4:00
p.m., eastern time; other OTC securities are valued at the last available bid
price prior to the time of valuation.     
   
  When market quotations are readily available, the debt securities of the
Portfolios (with the exception of the Money Market Portfolio) are valued based
upon market quotations, provided such quotations adequately reflect, in the
judgment of Mitchell Hutchins or the applicable Sub-Adviser, the fair value of
the securities. The amortized cost method of valuation generally is used with
respect to debt obligations with 60 days or less remaining to maturity unless
the Fund's board of trustees determines that this does not represent fair     
 
                                       26
<PAGE>
 
value. When market quotations for options and futures positions held by the
Portfolios are readily available, those positions are valued based upon such
quotations. Market quotations are not generally available for options traded in
the OTC market. When market quotations for options and futures positions, or
any other securities or assets of the Portfolios, are not available, they are
valued at fair value as determined in good faith by or under the direction of
the Fund's board of trustees. When practicable, such determinations are based
upon appraisals received from a pricing service using a computerized matrix
system or appraisals derived from information concerning the security or
similar securities received from recognized dealers in those securities.
   
  All securities quoted in foreign currencies are valued daily in U.S. dollars
on the basis of the foreign currency exchange rates prevailing at the time such
valuation is determined. Foreign currency exchange rates generally are
determined prior to the close of the NYSE. Occasionally, events affecting the
value of foreign securities and such exchange rates occur between the time at
which they are determined and the close of the NYSE, which events would not be
reflected in the computation of a Portfolio's net asset value. If events
materially affecting the value of such securities or currency exchange rates
occurred during such time period, the securities will be valued at their fair
value as determined in good faith by or under the direction of the board of
trustees. The foreign currency exchange transactions of the Strategic Fixed
Income, Global Income and Global Growth Portfolios conducted on a spot (that
is, cash) basis are valued at the spot rate for purchasing or selling currency
prevailing on the foreign exchange market. This rate under normal market
conditions differs from the prevailing exchange rate in an amount generally
less than one-tenth of one percent due to the costs of converting from one
currency to another.     
 
  The Money Market Portfolio values its portfolio securities in accordance with
the amortized cost method of valuation under Rule 2a-7 under the 1940 Act. To
use amortized cost to value its portfolio securities, the Portfolio must adhere
to certain conditions under that Rule relating to its investments, some of
which are discussed in the Prospectus. Amortized cost is an approximation of
market value, whereby the difference between acquisition cost and value at
maturity is amortized on a straight-line basis over the remaining life of the
instrument. The effect of changes in the market value of a security as a result
of fluctuating interest rates is not taken into account and thus the amortized
cost method of valuation may result in the value of a security being higher or
lower than its actual market value. In the event that a large number of
redemptions takes place at a time when interest rates have increased, the
Portfolio might have to sell portfolio securities prior to maturity and at a
price that might not be as desirable as the value at maturity.
 
  The Fund's board of trustees has established procedures for the purpose of
maintaining a constant net asset value of $1.00 per share for the Money Market
Portfolio, which include a review of the extent of any deviation of net asset
value per share, based on available market quotations, from the $1.00 amortized
cost per share. Should that deviation exceed 1/2 of 1%, the trustees will
promptly consider whether any action should be initiated to eliminate or reduce
material dilution or other unfair results to shareholders. Such action may
include redeeming shares in kind, selling portfolio securities prior to
maturity, reducing or withholding dividends and utilizing a net asset value per
share as determined by using available market quotations. The Money Market
Portfolio will maintain a dollar-weighted average portfolio maturity of 90 days
or less and will not purchase any instrument with a remaining maturity greater
than 13 months, will limit portfolio investments, including repurchase
agreements, to those U.S. dollar-denominated instruments that are of high
quality and that the trustees determine present minimal credit risks as advised
by Mitchell Hutchins and will comply with certain reporting and recordkeeping
procedures. There is no assurance that constant net asset per share value will
be maintained. In the event amortized cost ceases to represent fair value, the
board will take appropriate action.
 
  In determining the approximate market value of portfolio investments, the
Fund may employ outside organizations, which may use a matrix or formula method
that takes into consideration market indices, matrices, yield curves and other
specific adjustments. This may result in the securities being valued at a price
different from the price that would have been determined had the matrix or
formula method not been used.
 
                                       27
<PAGE>
 
All cash, receivables and current payables are carried at their face value.
Other assets, if any, are valued at fair value as determined in good faith by
or under the direction of the board of trustees.
 
                                     TAXES
 
  Shares of the Portfolios are offered only to insurance company separate
accounts that fund certain variable annuity and life insurance contracts
("Contracts"). See the applicable Contract prospectus for a discussion of the
special taxation of insurance companies with respect to such accounts and of
the Contract holders.
   
  Each Portfolio is treated as a separate corporation for federal income tax
purposes. In order to continue to qualify for treatment as a regulated
investment company ("RIC") under the Internal Revenue Code, each Portfolio must
distribute to its shareholders for each taxable year at least 90% of its
investment company taxable income (consisting generally of net investment
income, net short-term capital gain and, for certain Portfolios, net gains from
certain foreign currency transactions) ("Distribution Requirement") and must
meet several additional requirements. With respect to each Portfolio, these
requirements include the following: (1) the Portfolio must derive at least 90%
of its gross income each taxable year from dividends, interest, payments with
respect to securities loans and gains from the sale or other disposition of
securities or foreign currencies, or other income (including gains from
options, futures or forward currency contracts) derived with respect to its
business of investing in securities or those currencies ("Income Requirement");
(2) the Portfolio must derive less than 30% of its gross income each taxable
year from the sale or other disposition of securities, or any of the following,
that were held for less than three months--options or futures (other than those
on foreign currencies), or foreign currencies (or options, futures or forward
contract thereon) that are not directly related to the Portfolio's principal
business of investing in securities (or options and futures with respect to
securities) ("Short-Short Limitation"); (3) at the close of each quarter of the
Portfolio's taxable year, at least 50% of the value of its total assets must be
represented by cash and cash items, U.S. government securities, securities of
other RICs and other securities, with these other securities limited, in
respect of any one issuer, to an amount that does not exceed 5% of the value of
the Portfolio's total assets and that does not represent more than 10% of the
issuer's outstanding voting securities; and (4) at the close of each quarter of
the Portfolio's taxable year, not more than 25% of the value of its total
assets may be invested in securities (other than U.S. government securities or
the securities of other RICs) of any one issuer.     
   
  As noted in the Prospectus, each Portfolio must, and intends to continue to,
comply with the diversification requirements imposed by section 817(h) of the
Internal Revenue Code and the regulations thereunder. These requirements, which
are in addition to the diversification requirements mentioned above, place
certain limitations on the proportion of each Portfolio's assets that may be
represented by any single investment (which includes all securities of the same
issuer). For these purposes, each U.S. government agency or instrumentality is
treated as a separate issuer.     
 
  The use of hedging and related income strategies, such as selling (writing)
and purchasing options and futures contracts and entering into forward currency
contracts, involves complex rules that will determine for income tax purposes
the character and timing of recognition of the gains and losses a Portfolio
realizes in connection therewith. Income from the disposition of foreign
currencies (except certain gains therefrom that may be excluded by future
regulations), and income from transactions in options, futures and forward
currency contracts derived by a Portfolio with respect to its business of
investing in securities or foreign currencies, will qualify as permissible
income under the Income Requirement. However, income from the disposition of
options and futures contracts (other than those on foreign currencies) will be
subject to the Short-Short Limitation if they are held for less than three
months. Income from the disposition of foreign currencies, and options, futures
and forward contracts on foreign currencies, that are not directly related to a
Portfolio's principal business of investing in securities (or options and
futures with respect to securities) also will be subject to the Short-Short
Limitation if they are held for less than three months.
 
                                       28
<PAGE>
 
  If a Portfolio satisfies certain requirements, any increase in value of a
position that is part of a "designated hedge" will be offset by any decrease in
value (whether realized or not) of the offsetting hedging position during the
period of the hedge for purposes of determining whether the Portfolio satisfies
the Short-Short Limitation. Thus, only the net gain (if any) from the
designated hedge will be included in gross income for purposes of that
limitation. Each Portfolio will consider whether it should seek to qualify for
this treatment for its hedging transactions. To the extent a Portfolio does not
qualify for this treatment, it may be forced to defer the closing out of
certain options, futures and forward contracts beyond the time when it
otherwise would be advantageous to do so, in order for the Portfolio to
continue to qualify as a RIC.
 
  Dividends and interest received by a Portfolio may be subject to income,
withholding or other taxes imposed by foreign countries and U.S. possessions
that would reduce the yield on that Portfolio's securities. Tax conventions
between certain countries and the United States may reduce or eliminate these
foreign taxes, however, and many foreign countries do not impose taxes on
capital gains in respect of investments by foreign investors.
 
  Any Portfolio that may purchase or hold equity securities may invest in
"passive foreign investment companies" ("PFICs"). A PFIC is a foreign
corporation that, in general, meets either of the following tests: (1) at least
75% of its gross income is passive or (2) an average of at least 50% of its
assets produce, or are held for the production of, passive income. Under
certain circumstances, a Portfolio that holds stock of a PFIC will be subject
to federal income tax on a portion of any "excess distribution" received on the
stock or of any gain on disposition of the stock (collectively "PFIC income"),
plus interest thereon, even if the Portfolio distributes the PFIC income as a
taxable dividend to its shareholders. The balance of the PFIC income will be
included in the Portfolio's investment company taxable income and, accordingly,
will not be taxable to it to the extent that income is distributed to its
shareholders.
   
  If a Portfolio invests in a PFIC and elects to treat the PFIC as a "qualified
electing fund," then in lieu of the foregoing tax and interest obligation, the
Portfolio will be required to include in income each year its pro rata share of
the qualified electing fund's annual ordinary earnings and net capital gain
(the excess of net long-term capital gain over net short-term capital loss),
even if they are not received by the Portfolio; those amounts most likely would
have to be distributed to the Portfolio's shareholders to satisfy the
Distribution Requirements. In most instances it will be very difficult, if not
impossible, to make this election because of certain requirements thereof.     
 
  Pursuant to proposed regulations, open-end RICs, such as the Portfolios,
would be entitled to elect to "mark-to-market" their stock in certain PFICs.
"Marking-to-market," in this context, means recognizing as gain for each
taxable year the excess, as of the end of that year, of the fair market value
of each such PFIC's stock over the owner's adjusted basis in that stock
(including mark-to-market gain for each prior year for which an election was in
effect).
 
  The foregoing is only a general summary of some of the important federal
income tax considerations generally affecting the Portfolios and their
shareholders. No attempt is made to present a complete explanation of the
federal tax treatment of the Portfolios' activities, and this discussion is not
intended as a substitute for careful tax planning. Accordingly, potential
investors are urged to consult their own tax advisers for more detailed
information and for information regarding any state, local or foreign taxes
applicable to the Portfolios and to dividends and other distributions
therefrom.
 
                                   DIVIDENDS
 
  MONEY MARKET PORTFOLIO. Shares begin earning dividends on the day of
purchase; dividends are accrued to shareholder accounts daily and are
automatically reinvested in Portfolio shares monthly. The Portfolio does not
expect to realize net capital gain. In the event of a redemption of all of the
shares held by a shareholder, all accrued dividends declared on the shares up
to the date of redemption are credited to the shareholder's account.

  The Fund's board of trustees may revise the above dividend policy, or
postpone the payment of dividends, if the Portfolio should have or anticipate
any large unexpected expense, loss or fluctuation in net assets that, in the
opinion of the board, might have a significant adverse effect on shareholders.
To date, no situation has arisen to cause the board of trustees to take any
such action.

  The Fund is an entity of the type commonly known as a "Massachusetts business
trust." Under Massachusetts law, shareholders could, under certain
circumstances, be held personally liable for the obligations of the Fund or a
Portfolio. However, the Fund's Declaration of Trust disclaims shareholder
liability for acts or obligations of the Fund or any Portfolio and requires
that notice of such disclaimer be given in each note, bond, contract,
instrument, certificate or undertaking made or issued by the trustees or by any
officers or officer by or on behalf of the Fund, the trustees or any of them in
connection with the Fund. The Declaration of Trust provides for indemnification
from Fund or Portfolio property, as appropriate, for all losses and expenses of
any shareholder held personally liable for the obligations of the Fund or
Portfolio. Thus, the risk of a shareholder's incurring financial loss on
account of shareholder liability is limited to circumstances in which the Fund
or Portfolio itself would be unable to meet its obligations, a possibility that
Mitchell Hutchins believes is remote and not material. Upon payment of any
liability incurred by a shareholder of a Portfolio, the shareholder paying such
liability will be entitled to reimbursement from the general assets of the
Portfolio. The trustees intend to conduct the operations of the Fund so as to
avoid, as far as possible, ultimate liability of the shareholders for
liabilities of the Fund and the Portfolios.

                DESCRIPTION OF COMMERCIAL PAPER AND BOND RATINGS
 
  COMMERCIAL PAPER RATINGS. Moody's employs the designation "Prime-1," "Prime-
2" and "Prime-3" to indicate the repayment capacity of issuers of commercial
paper. Issuers rated Prime-1 have a superior capacity for repayment of short-
term promissory obligations. Prime-1 repayment capacity will normally be
evidenced by the following characteristics: leading market positions in well-
established industries; high rates of return on funds employed; conservative
capitalization structures with moderate reliance on debt and ample asset
protection; broad margins in earnings coverage of fixed financial charges and
high internal cash generation; well-established access to a range of financial
markets and assured sources of alternate liquidity. Issuers rated Prime-2 have
a strong capacity for repayment of short-term promissory obligations. This will
normally be evidenced by many of the characteristics cited above but to a
lesser degree. Earnings trends and coverage ratios, while sound, will be more
subject to variation. Capitalization characteristics, while still appropriate,
may be more affected by external conditions. Ample alternate liquidity is
maintained. Issuers rated Prime-3 have an acceptable capacity for repayment of
short-term promissory obligations. The effect of industry characteristics and
market composition may be more pronounced. Variability in earnings and
profitability may result in changes in the level of debt protection
measurements and the requirement for relatively high financial leverage.
Adequate alternate liquidity is maintained. Not Prime. Issuers assigned this
rating do not fall within any of the Prime rating categories.
 
  S&P's ratings of commercial paper are graded into four categories ranging
from "A" for the highest quality obligations to "D" for the lowest. A--Issues
assigned this highest rating are regarded as having the greatest capacity for
timely payment. Issues in this category are delineated with numbers 1, 2, and 3
to indicate the relative degree of safety. A-1--This designation indicates that
the degree of safety regarding timely payment is either overwhelming or very
strong. Those issues determined to possess overwhelming safety characteristics
are denoted with a plus (+) sign designation. A-2--Capacity for timely payments
on issues with this designation is strong. However, the relative degree of
safety is not as high as for issues designated "A-1." A-3--Issues carrying this
designation have a satisfactory capacity for timely payment. They are, however,
somewhat more vulnerable to the adverse effects of changes in circumstances
than obligations carrying the higher designations. B--Issues rated B are
regarded as having only an adequate capacity for timely payment. However, such
capacity may be damaged by changing conditions or short-term adversities. C--
This rating is assigned to short-term debt obligations with a doubtful capacity
for payment. D --This rating indicates that the issue is either in default or
is expected to be in default upon maturity.
 
  CORPORATE DEBT SECURITIES. Moody's rates the long-term debt securities issued
by various entities from "Aaa" to "D". Aaa--Best quality. These securities
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--High quality by
all standards. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities, 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--Upper medium grade obligations. These bonds possess many favorable
investment attributes. 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--Medium grade obligations. Interest
payments and principal security appear adequate for the present but certain
protective elements may be lacking or may be characteristically unreliable over
any great length of time. Such bonds lack outstanding investment
characteristics and, in fact, have speculative characteristics as well. Ba--
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 thereby not well safeguarded during both good and bad times over
the future. Uncertainty of position characterizes bonds in this class. 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--Poor standing. Such
issues may be in default or there may
 
                                       31
<PAGE>
 
be present elements of danger with respect to principal or interest. Ca--
Obligations which are speculative in a high degree. Such issues are often in
default or have other marked shortcomings. C--Lowest rated class of bonds;
issues so rated can be regarded as having extremely poor prospects of ever
attaining any real investment standing.
 
  Note: Moody's may apply numerical modifiers, 1, 2 and 3 in each generic
rating classification from Aa through B in its corporate bond 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 the
modifier 3 indicates that the issue ranks in the lower end of its generic
rating category.
 
  S&P also rates the long-term debt securities of various entities in
categories ranging from "AAA" to "D" according to quality. AAA--Highest grade.
Capacity to pay interest and repay principal extremely strong. AA--High grade.
Debt rated AA has a very strong capacity to pay interest and repay principal
and differs from AAA issues only in a small degree. 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. BBB--Regarded as having adequate capacity to pay interest and repay
principal. Whereas these bonds normally exhibit adequate protection parameters,
adverse economic conditions or changing circumstances are more likely to lead
to a weakened capacity to pay interest and repay principal than for debt in
higher rated categories. BB, B, CCC, CC, C--Regarded, on balance, as
predominantly speculative with respect to capacity to pay interest and repay
principal in accordance with the terms of the obligation. BB indicates the
lowest degree of speculation and C the highest degree of speculation. While
such debt will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions. CI--Reserved for income bonds on which no interest is being paid.
D--In default, and payment of interest and/or repayment of principal is in
arrears.
 
  Plus (+) or Minus (-): The ratings from "AA" to "CCC" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

     Item 27.  Indemnification

          Section 2 of "Indemnification" in Article X of the Declaration of
     Trust provides that the appropriate series of the Registrant will
     indemnify its trustees and officers to the fullest extent permitted by law
     against claims and expenses asserted against or incurred by them by virtue
     of being or having been a trustee or officer; provided that no such person
     shall be indemnified where there has been an adjudication or other
     determination, as described in Article X, that such person is liable to
     the Registrant or its shareholders by reason of willful misfeasance, bad
     faith, gross negligence or reckless disregard of the duties involved in
     the conduct of his or her office or did not act in good faith in the
     reasonable belief that his action was in the best interest of the
     Registrant.  Section 2 of "Indemnification" in Article X also provides
     that the Registrant may maintain insurance policies covering such rights
     of indemnification.

          Additionally, "Limitation of Liability" in Article X of the
     Declaration of Trust provides that the trustees or officers of the
     Registrant shall not be personally liable to any person extending credit
     to, contracting with or having a claim against the Trust or a particular

                                         C-6
<PAGE>
 
     series thereof; and that, provided they have exercised reasonable care and
     have acted under the reasonable belief that their actions are in the best
     interest of the Registrant, the trustees and officers shall not be liable
     for neglect or wrongdoing by them or any officer, agent, employee or
     investment adviser of the Registrant.

          Section 2 of Article XI of the Declaration of Trust additionally
     provides that, subject to the provisions of Section 1 of Article XI and to
     Article X, trustees shall not be liable for errors of judgment or mistakes
     of fact or law, or for any act or omission in accordance with the advice
     of counsel or other experts, or failing to follow such advice, with
     respect to the meaning and operation of the Declaration of Trust.

          Article XI of the By-Laws provides that the Registrant may purchase
     and maintain insurance on behalf of any person who is or was a trustee,
     officer or employee of the Trust, or is or was serving at the request of
     the Trust as a trustee, officer or employee of a corporation, partnership,
     joint venture, trust or other enterprise against any liability asserted
     against him or her and incurred by him or her in any such capacity or
     arising out of his or her status as such, whether or not the Registrant
     would have the power to indemnify him or her against such liability,
     provided that the Registrant may not acquire insurance protecting any
     trustee or officer against liability to the Registrant or the Registrant
     or its shareholders to which he or she would otherwise be subject by
     reason of willful misfeasance, bad faith, gross negligence, or reckless
     disregard of the duties involved in the conduct of his or her office.

          Section 9 of the Investment Advisory and Administration Contract
     between Mitchell Hutchins Asset Management Inc. ("Mitchell Hutchins") and
     the Registrant provides that Mitchell Hutchins shall not be liable for any
     error of judgment or mistake of law or for any loss suffered by Registrant
     in connection with the matters to which the Contract relates, except for a
     loss resulting from the willful misfeasance, bad faith, or gross
     negligence of Mitchell Hutchins in the performance of its duties or from
     its reckless disregard of its obligations and duties under the Contract. 
     Section 10 of the Contract provides that the trustees shall not be liable
     for any obligations of the Registrant or any series under the Contract and
     that Mitchell Hutchins shall look only to the assets and property of the
     Registrant in settlement of such right or claim and not to the assets and
     property of the trustees.

          Section 7 of each Sub-Advisory Agreement provides that the applicable
     sub-adviser shall not be liable for any error of judgment or mistake of
     law or for any loss suffered by the applicable Portfolio, the Registrant
     or its shareholders or by Mitchell Hutchins in connection with the matters
     to which the Sub-Advisory Agreement relates, except a loss resulting from
     willful misfeasance, bad faith or gross negligence on the sub-adviser's
     part in the performance of its duties or from reckless disregard by it of
     its obligations and duties under the Sub-Advisory Agreement.

          Insofar as indemnification for liabilities arising under the
     Securities Act of 1933, as amended, may be provided to trustees, officers

                                      C-7
<PAGE>
 
     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
     or payment pursuant to any insurance policy) is asserted against the
     Registrant by such trustee, officer or controlling person in connection
     with the securities 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.

                                SUB-ADVISORY AGREEMENT


          Agreement  made as  of June 8,  1995, between  MITCHELL HUTCHINS ASSET
     MANAGEMENT  INC. ("Mitchell  Hutchins"),  a  Delaware corporation,  and  GE
     Investment Management Incorporated ("Sub-Adviser"),  a Delaware corporation
     (the "Agreement"). 


                                       RECITALS

          (1)  Mitchell  Hutchins has  entered into  a Investment  Advisory  and
     Administration  Contract dated  April  21, 1988,  ("Management  Agreement")
     with PaineWebber Series Trust ("Trust"), an  open-end management investment
     company registered under  the Investment Company  Act of  1940, as  amended
     ("1940 Act")  with  respect to  the Global  Growth Portfolio  ("Portfolio")
     series of the Trust; and

          (2)  Mitchell Hutchins  wishes to  retain the  Sub-Adviser to  furnish
     certain  investment  advisory   services  to  Mitchell  Hutchins   and  the
     Portfolio, and the Sub-Adviser is willing to furnish those services;

          NOW, THEREFORE, in consideration of  the premises and mutual covenants
     herein contained, the parties agree as follows:

          1.   Appointment.   Mitchell Hutchins hereby  appoints the Sub-Adviser
     as an investment sub-adviser with  respect to the Portfolio for  the period
     and on the terms  set forth in this Agreement. The Sub-Adviser accepts that
     appointment and  agrees to render  the services herein  set forth, for  the
     compensation herein provided.

          2.   Duties as Sub-Adviser.

          (a)  Subject to the supervision of and  any guidelines adopted by  the
     Trust's Board of  Trustees (the "Board"),  the Sub-Adviser  will provide  a
     continuous  investment  program for  the  Portfolio,  including  investment
     research and management.  The Sub-Adviser will determine from time to  time
     what investments  will be  purchased, retained  or sold  by the  Portfolio.
     The Sub-Adviser  will be responsible  for placing purchase  and sell orders
     for investments and for other  related transactions.  The  Sub-Adviser will
     provide services under  this Agreement in accordance  with the  Portfolio's
     investment  objective,   policies  and  restrictions   as  stated  in   the
     Portfolio's Registration Statement.

          (b)  The Sub-Adviser agrees that, in placing  orders with brokers,  it
     will obtain the best net result in  terms of price and execution;  provided
     that,  on behalf of the Portfolio,  the Sub-Adviser may, in its discretion,
     use brokers who provide the  Portfolio with research, analysis,  advice and
     similar  services  to  execute  portfolio  transactions  on  behalf  of the
     Portfolio, and  the Sub-Adviser  may pay  to those  brokers  in return  for
     brokerage and research services a higher commission  than may be charged by
     other brokers, subject  to the Sub-Adviser's determining in good faith that
<PAGE>
 
     such  commission  is  reasonable   in  terms   either  of  the   particular
     transaction or  of the  overall responsibility  of the  Sub-Adviser to  the
     Portfolio and its other  clients and that the total commissions paid by the
     Portfolio will be reasonable  in relation to the benefits to  the Portfolio
     over  the long term. In no  instance will portfolio securities be purchased
     from or sold  to the Sub-Adviser, or any  affiliated person thereof, except
     in  accordance  with   the  federal  securities  laws  and  the  rules  and
     regulations  thereunder.  Whenever the  Sub-Adviser  simultaneously  places
     orders  to purchase or  sell the same security  on behalf  of the Portfolio
     and one or more other accounts advised by the Sub-Adviser, the orders  will
     be  allocated as to  price and amount  among all such  accounts in a manner
     believed to be  equitable by  the Sub-Adviser  over time  to each  account.
     Mitchell  Hutchins  recognizes  that  in  some  cases  this  procedure  may
     adversely affect the results obtained for the Portfolio.

          (c)  The  Sub-Adviser will maintain all books and  records required to
     be maintained  by the Sub-Adviser  pursuant to the  1940 Act and the  rules
     and  regulations promulgated  thereunder with  respect  to transactions  on
     behalf  of the Portfolio, and will furnish  the Board and Mitchell Hutchins
     with such  periodic and special reports  as the Board or  Mitchell Hutchins
     reasonably may request. In compliance  with the requirements of  Rule 31a-3
     under the  1940 Act, the  Sub-Adviser hereby agrees that  all records which
     it maintains  for the Portfolio  are the property  of the Trust, agrees  to
     preserve for the  periods prescribed by Rule  31a-2 under the 1940  Act any
     records which  it maintains  for the  Trust and  which are  required to  be
     maintained  by  Rule 31a-1  under  the  1940  Act, and  further  agrees  to
     surrender promptly  to the  Trust any  records which  it maintains for  the
     Trust upon request by the Trust.

          (d)  At such times as  shall be reasonably requested  by the Board  or
     Mitchell  Hutchins,  the Sub-Adviser  will provide  the Board  and Mitchell
     Hutchins  with economic  and  investment analyses  and  reports as  well as
     quarterly  reports  setting  forth the  Portfolio's  performance  and  make
     available to the  Board and Mitchell Hutchins any economic, statistical and
     investment services normally available to institutional  or other customers
     of the Sub-Adviser.

          (e)  In accordance with  procedures adopted by  the Board,  as amended
     from time  to time,  the Sub-Adviser  is responsible  for assisting  in the
     fair valuation  of any  illiquid portfolio  securities and  will assist  in
     providing  independent sources  of  market value  for  all other  portfolio
     securities.  

          3.   Further Duties.   In all matters  relating to  the performance of
     this Agreement, the  Sub-Adviser will act  in conformity  with the  Trust's
     Trust  Instrument, By-Laws and  currently effective  registration statement
     under   the  1940   Act   and  any   amendments   or  supplements   thereto
     ("Registration   Statement")  and   with  the   written   instructions  and
     directions of  the Board  and Mitchell  Hutchins and  will comply with  the
     requirements of  the 1940  Act,  the Investment  Advisers Act  of 1940,  as
     amended,  ("Advisers Act"), the rules  under each, and  Subchapter M of the
     Internal Revenue Code  as applicable to regulated investment companies.  In

                                        - 2 -
<PAGE>
 
     addition, the Sub-Adviser  will act in conformity with all other applicable
     federal  and  state  laws  and  regulations  either  as  reflected  in  the
     Registration Statement or otherwise provided in  writing to the Sub-Adviser
     by  Mitchell  Hutchins.  Mitchell   Hutchins  agrees  to  provide  to   the
     Sub-Adviser copies of  the Trust's Trust Instrument,  By-Laws, Registration
     Statement,  written instructions and directions  of the  Board and Mitchell
     Hutchins,  and any amendments or  supplements to any  of these materials as
     soon as practicable after such materials become available.

          4.   Exclusivity.  During  the term of this Agreement, the Sub-Adviser
     agrees that it  will not  provide investment advice  on a discretionary  or
     non-discretionary basis for  any global equity investment  products offered
     to retail  customers  in the  United  States  by broker-dealers  listed  on
     Schedule A.  The Sub-Adviser  shall deliver to Mitchell Hutchins in writing
     prompt  and  regular  reports  of  the  Sub-Adviser's  investment  advisory
     activities in sufficient  detail to permit Mitchell Hutchins to monitor the
     terms of this Agreement.

          5.   Expenses.   During the  term of  this Agreement,  the Sub-Adviser
     will bear  all expenses incurred  by it in  connection with its  investment
     sub-advisory services under this Agreement.

          6.   Compensation.

          (a)  For  the services  provided  and  the  expenses  assumed  by  the
     Sub-Adviser  pursuant  to  this  Agreement,  Mitchell   Hutchins,  not  the
     Portfolio,  will pay to  the Sub-Adviser a fee,  computed daily and payable
     monthly, as computed  in the manner set forth  in Schedule B, together with
     a schedule showing the manner in which the fee was computed.

          (b)  The fee  shall  be computed  daily  and  payable monthly  to  the
     Sub-Adviser on or before the fifteenth business day  of the next succeeding
     calendar month.

          (c)  If this Agreement becomes effective or terminates before  the end
     of any month, the fee for  the period from the effective date to the end of
     the month or from the beginning  of such month to the date  of termination,
     as the  case may be,  shall be prorated  according to the proportion  which
     such period  bears  to  the  full  month in  which  such  effectiveness  or
     termination occurs.

          7.   Limitation Of Liability.   The  Sub-Adviser shall  not be  liable
     for any  error of judgment  or mistake of  law or for any  loss suffered by
     the Portfolio, the  Trust or  its shareholders or  by Mitchell Hutchins  in
     connection  with the matters to which this Agreement relates, except a loss
     resulting from  willful misfeasance, bad  faith or gross  negligence on its
     part in the performance  of its duties or from reckless  disregard by it of
     its obligations and duties under this Agreement.

     directors, and any person  who controls GEIM within the meaning  of Section
     15 of  the Securities  Act of  1933 ("1933  Act") for  any loss  or expense

     ("PaineWebber"),  has been found  at fault (i) by  the final  judgment of a
     court  of competetent  jurisdiction or (ii)  in any order  of settlement of

     (ii) in any order  of settlement of any claim, demand,  action or suit that
     has been approved by the Board of Directors of GEIM or GE.

     warrants and agrees as follows:

     self-regulatory  agency,  necessary to  be  met  in  order  to perform  the
     services contemplated  by this Agreement;  (iv) has the  authority to enter

          (b)  The Sub-Adviser  has adopted a  written code  of ethics complying
     with the requirements of  Rule 17j-1  under the 1940  Act and will  provide
     Mitchell  Hutchins and  the  Board with  a  copy of  that  code of  ethics,
     together with evidence of its  adoption.  Within fifteen days of the end of
     the last calendar  quarter of each year  that this Agreement is  in effect,
     the  president or  a  vice-president of  the  Sub-Adviser shall  certify to
     Mitchell Hutchins that  the Sub-Adviser has complied with  the requirements
     of Rule  17j-1  during  the  previous  year and  that  there  has  been  no
     violation of the Sub-Adviser's  code of ethics or, if such a  violation has
     occurred, that appropriate  action was taken in response to such violation.
     Upon the  written  request  of Mitchell  Hutchins,  the  Sub-Adviser  shall

          (c)  The  Sub-Adviser has  provided Mitchell  Hutchins with  a copy of
     its  Form  ADV as  most  recently filed  with the  Securities  and Exchange
     Commission  ("SEC") and promptly will  furnish a copy  of all amendments to
     Mitchell Hutchins at least annually.

     Thereafter, if not  terminated, this Agreement will  continue automatically
     for  successive  periods  of  twelve   months  each,  provided  that   such
     continuance is specifically approved at least annually  (i) by a vote of  a
     majority  of  those trustees  of  the Trust  who  are not  parties  to this
     Agreement or  interested persons  of any such  party, cast  in person at  a
     meeting called for the purpose  of voting on such approval, and (ii) by the
     Board or by the holders of  a vote of a majority of the outstanding  voting
     securities of the Portfolio.

          (c)  Notwithstanding the foregoing,  this Agreement may be  terminated

     material breach  by  the Sub-Adviser  of  any  of the  representations  and

     this Agreement,  including circumstances  such as  financial insolvency  of
     the Sub-Adviser  or other  circumstances that  could  adversely affect  the
     Portfolio.   The  Sub-Adviser  may terminate  this  Agreement at  any time,
     without  the  payment  of  any  penalty, on  120  days'  written  notice to
     Mitchell  Hutchins. This  Agreement  will  terminate automatically  in  the
     event of its assignment or upon termination of the Management Agreement.

          12.  Amendment of this Agreement.   No provision of this Agreement may
     be  changed,  waived, discharged  or  terminated  orally,  but  only by  an
     instrument in writing signed by the party against which enforcement of  the
     change, waiver, discharge  or termination is  sought, and  no amendment  to
     the terms of this Agreement shall be effective until  approved by vote of a
     majority  of the  Portfolio's  outstanding  voting securities  (unless  the
     Trust receives an SEC order  permitting it to modify the Agreement  without
     such vote).

          13.  Governing Law.   This Agreement shall be construed in  accordance
     with the  1940 Act and  the laws of the  State of Delaware,  without giving
     effect to the conflicts of laws principles thereof. To the extent that  the

     convenience  of reference only and in  no way define or  delimit any of the
     provisions hereof or  otherwise affect their construction or effect. If any
     provision  of this  Agreement shall  be held  or  made invalid  by a  court
     decision, statute,  rule  or otherwise,  the  remainder of  this  Agreement
     shall  not be affected  thereby. This Agreement  shall be  binding upon and
     shall  inure to  the benefit  of the  parties hereto  and  their respective

     securities laws reflected in any provision  of this Agreement is made  less
     restrictive by a rule, regulation or order  of the SEC, whether of  special
     or general application, such provision  shall be deemed to  incorporate the
     effect of such rule, regulation or order.  This Agreement may be signed  in

                            SUB-ADVISORY AGREEMENT

     Agreement made as of     , 1995 ("Agreement") between MITCHELL HUTCHINS 
ASSET MANAGEMENT INC., a Delaware corporation ("Mitchell Hutchins"), and PACIFIC
INVESTMENT MANAGEMENT COMPANY, a Delaware general partnership ("Sub-Adviser").

                                   RECITALS

     (1)  Mitchell Hutchins has entered into an Investment Advisory and 
Administration Contract dated April 21, 1988, as supplemented by an Investment 
Advisory and Administration Fee Agreement dated May 1, 1990 (together, referred 
to as "Advisory Contract") with PaineWebber Series Trust ("Trust"), as open-end 
management investment company registered under the Investment Company Act of 
1940, as amended ("1940 Act") with respect to the Strategic Fixed Income 
Portfolio ("Portfolio") series of the Trust (formerly named "Government 
Portfolio"); and 

     (2)  Mitchell Hutchins wishes to retain the Sub-Adviser to furnish certain 
investment advisory services to the Portfolio, and the Sub-Adviser is willing to
furnish those services;

     NOW, THEREFORE, in consideration of the premises and mutual covenants 
herein contained, the parties agree as follows:

     1.   Appointment.  Mitchell Hutchins hereby appoints the Sub-Adviser as an 
investment sub-adviser with respect to the Portfolio for the period and on the 
terms set forth in this Agreement. The Sub-Adviser accepts that appointment and 
agrees to render the services herein set forth, for the compensation herein 
provided.

     2.   Duties as Sub-Adviser.

     (a)  Subject to the supervision of and any guidelines adopted by the 
Trust's Board of Trustees ("Board") and Mitchell Hutchins, the Sub-Adviser will 
provide a continuous investment program for the Portfolio, including investment 
research and management. The Sub-Adviser will determine from time to time what 
investments will be purchased, retained or sold by the Portfolio. The 
Sub-Adviser will be responsible for placing purchase and sell orders for 
investments and for other related transactions. The Sub-Adviser will provide 
services under this Agreement in accordance with the Portfolio's investment 
objective, policies and restrictions as stated in the Trust's Registration 
Statement.

     (b)  The Sub-Adviser agrees that, in placing orders with brokers, it will 
obtain the best net result in terms of price and execution; provided that, on 
behalf of the Portfolio, the Sub-Adviser may, in its discretion, use brokers who
provide the Sub-Adviser with research, analysis, advice and similar services to 
execute portfolio transactions, and the Sub-Adviser may pay to those brokers in 
return for brokerage and research services a higher commission than may be 
charged by other brokers, subject to the Sub-Adviser's determining in good faith
that such commission is reasonable in terms either of the particular transaction
or of the overall
<PAGE>
 
responsibility of the Sub-Adviser to the Portfolio and its other clients and 
that the total commissions paid by the Portfolio will be reasonable in relation 
to the benefits to the Portfolio over the long term.  In no instance will 
portfolio securities be purchased from or sold to the Sub-Adviser, or any 
affiliated person thereof, except in accordance with the federal securities laws
and the rules and regulations thereunder.  The Sub-Adviser may aggregate sales 
and purchase orders with respect to the assets of the Portfolio with similar 
orders being made simultaneously for other accounts advised by the Sub-Adviser 
or its affiliates.  Whenever the Sub-Adviser simultaneously places orders to 
purchase or sell the same security on behalf of the Portfolio and one or more 
other accounts advised by the Sub-Adviser, the orders will be allocated as to 
price and amount among all such accounts in a manner believed to be equitable 
over time to each account.  Mitchell Hutchins recognizes that in some cases this
procedure may adversely affect the results obtained for the Portfolio.

     (c)  The Sub-Adviser will maintain all books and records required to be 
maintained by the Sub-Adviser pursuant to the 1940 Act and the rules and 
regulations promulgated thereunder with respect to transactions by the 
Sub-Adviser on behalf of the Portfolio, and will furnish the Board and Mitchell
Hutchins with such periodic and special reports as the Board or Mitchell 
Hutchins reasonably may request.  In compliance with the requirements of Rule 
31a-3 under the 1940 Act, the Sub-Adviser hereby agrees that all records which 
it maintains for the Portfolio are the property of the Trust, agrees to preserve
for the periods prescribed by Rule 31a-2 under the 1940 Act any records which it
maintains for the Trust and which are required to be maintained by Rule 31a-1 
under the 1940 Act, and further agrees to surrender promptly to the Trust any 
records which it maintains for the Portfolio upon request by the Trust.

     (d)  At such times as shall be reasonably requested by the Board or 
Mitchell Hutchins, the Sub-Adviser will provide the Board and Mitchell Hutchins,
with economic and investment analyses and reports as well as quarterly reports
setting forth the Portfolio's performance and make available to the Board and
Mitchell Hutchins any economic, statistical and investment services normally
available to institutional or other customers of the Sub-Adviser.

     (e)  In accordance with procedures adopted by the Board, as amended from 
time to time, the Sub-Adviser is responsible for assisting in the fair valuation
of all portfolio securities and will use its reasonable efforts to arrange for 
the provision of a price(s) from a party(ies) independent of the Sub-Adviser for
each portfolio security for which the custodian does not obtain prices in the 
ordinary course of business from an automated pricing service.

     3.   Further Duties.  In all matters relating to the performance of this 
Agreement, the Sub-Adviser will act in conformity with the Trust's Trust 
Instrument, By-Laws and currently effective registration statement under the 
1940 Act and any amendments or supplements thereto ("Registration Statement") 
and with the written instructions and written directions of the Board and 
Mitchell Hutchins and will comply with the requirements of the 1940 Act, the 
Investment Advisers Act of 1940, as

                                      -2-
<PAGE>
 

amended ("Advisers Act"), the rules under each. Subchapter M of the Internal 
Revenue Code ("Code") as applicable to regulated investment companies, the 
diversifications requirements applicable to the Portfolio under Section 817(h) 
of the Code and all other applicable federal and state laws and regulations. 
Mitchell Hutchins agrees to provide to the Sub-Adviser copies of the Trust's 
Trust Instrument, By-Laws, Registration Statement, written instructions and 
directions of the Board and Mitchell Hutchins, and any amendments or supplements
to any of these materials as soon as practicable after such materials become 
available; provided, however, that the Sub-Adviser's duty under this Agreement 
to act in conformity with any document, instruction, or guidelines produced by 
the Trust or Mitchell Hutchins shall not arise until it has been delivered to 
the Sub-Adviser. Any changes to the objectives, policies or restrictions will 
make due allowance for the time within which the Sub-Adviser shall have to come 
into compliance.

     4.   Expenses.  During the term of this Agreement, the Sub-Adviser will
bear all expenses incurred by it in connection with its services under this
Agreement. The Sub-Adviser shall not be responsible for any expenses incurred by
the Trust, the Portfolio or Mitchell Hutchins.

     5.   Compensation.

     (a)  For the services provided and the expenses assumed by the Sub-Adviser 
pursuant to this Agreement, Mitchell Hutchins, not the Portfolio, will pay to 
the Sub-Adviser a fee, computed daily and payable monthly, at an annual rate of 
0.25% of the Portfolio's average daily net assets (computed in the manner 
specified in the Advisory Contract), and will provide the Sub-Adviser with a 
schedule showing the manner in which the fee was computed.

     (b)  The fee shall be computed daily and payable monthly to the Sub-Adviser
on or before the last business day of the next succeeding calendar month.


     (c)  For those periods in which Mitchell Hutchins has agreed to waive all 
or a portion of its management fee, Mitchell Hutchins may ask the Sub-Adviser to
waive the same proportion of its fees, but the Sub-Adviser is under no 
obligation to do so.

     (d)   If this Agreement becomes effective or terminates before the end of 
any month, the fee for the period from the effective date to the end of the 
month or from the beginning of such month to the date of termination, as the 
case may be, shall be prorated according to the proportion which such period 
bears to the full month in which such effectiveness or termination occurs.

     6.   Limitation of Liability.  The Sub-Adviser shall not be liable for any 
error of judgement or mistake of law or for any loss suffered by the Portfolio, 
the Trust or its shareholders or by Mitchell Hutchins in connection with the 
matters to which this Agreement relates, except a loss resulting from willful 
misfeasance, bad faith or gross negligence on its 

                                      -3-

<PAGE>
 
part in the performance of its duties or form reckless disregard by it of its 
obligations and duties under this Agreement.

     7. Representations of Sub-Adviser. The Sub-Adviser represents, warrants and
agrees as follows:

Agreement; (iv) has the authority to enter into and perform the services

adoption. Within fifteen days of the end of the last calender quarter of each

Sub-Adviser shall certify to Mitchell Hutchins that the Sub-Adviser has complied
