Dear Contract Owner:
 
    We are pleased to present the June 30, 1995 Semi-Annual Report for
Milestones, offered exclusively through PaineWebber. This report contains
important information about the PaineWebber Life Variable Annuity Account and
PaineWebber Series Trust, including financial statements for the six months
ended June 30, 1995.
 
INVESTMENT OVERVIEW--DOMESTIC
 
    During the six months ended June 30, 1995, the pace of U.S. economic growth
was perceived to have slowed in response to the Federal Reserve Board's repeated
increases in the benchmark Federal Funds rate, the rate banks charge each other
for overnight borrowing. The Federal Reserve Board raised the Federal Funds rate
to 6.0% after seven short-term interest rate hikes between February 1994 and
February 1995. On July 6, 1995, the Federal Reserve cut the benchmark Federal
Funds rate by 0.25% to 5.75%. This decrease, the first in nearly three years,
signals that the Federal Reserve Board believes that inflationary pressures have
eased enough to accommodate an adjustment in monetary conditions.
 
    The U.S. bond and stock markets rallied in the first half of 1995. Interest
rates trended downward, as the perception that the Federal Reserve had won its
battle with inflation and that the next policy action would be to lower
short-term interest rates became widespread. Strength in corporate earnings
pushed stock prices higher. Other important developments concerning the U.S.
economy during the six months included the dismal performance of the dollar and
efforts in Washington to implement a plan to balance the budget. Employment
reports indicated a slowing economy, with consumer spending declining
significantly from 1994 and consumer credit reports showing high ratios of
installment debt to disposable income. Side effects of higher interest rates
lingered, however. Markets for new and existing homes were sluggish until the
close of the six-month period, despite historically attractive mortgage rates.
Although the U.S. economy appears to have been flat in the second quarter, the
second half of 1995 should show signs of further, albeit slower, growth.
 
INVESTMENT OVERVIEW--GLOBAL
 
    During the six months ended June 30, 1995, two crises shook the financial
world and led to an investor flight to quality. First was the overall decline in
emerging markets on the heels of the Mexican government's devaluation of the
peso in December 1994, followed by the unraveling of Barings plc, the British
investment bank, in February 1995. Another important development was the U.S.
dollar's continued depreciation against the yen and the Deutschemark.
 
    1995 began with violent swings in currencies. Countries with weakening
currencies--the United States, Italy, Spain, Sweden and Mexico--might experience
improving trade balances, but lower than expected growth. For the United States,
where 40% of total exports go to emerging markets and over 10% to Latin America,
declining exports to these markets could significantly impact U.S. GDP growth.
Those countries that witnessed strong upward moves in currencies--Germany, Japan
and Switzerland--might be impacted by lower growth as well. Both Japan's and
Germany's recent economic turnarounds were due to strong export growth, which
will probably be negatively impacted by the strong yen and Deutschemark.
 
MONEY MARKET PORTFOLIO
 
    In anticipation of a possible Federal Reserve Board action, the Portfolio
maintained a neutral weighted average maturity during the six months ended June
30, 1995. The Federal Reserve's
 
                                       1
<PAGE>
consecutive increases in the Federal Funds rate during 1994 and early 1995 were
implemented to slow the pace of economic growth and forestall inflation.
However, on July 6, 1995, the Federal Reserve cut the Federal Funds rate by
0.25%, reducing the Federal Funds rate to 5.75%.
 
    The Portfolio's money market instruments' seven-day average yield was 6.95%
as of June 30, 1995. Going forward, the Portfolio will maintain a neutral
weighted average maturity as short-term rates find stability. On June 30, 1995,
the Portfolio's weighted average maturity was 35 days. The Federal Reserve Board
appears to have engineered a soft landing and it seems as though the next
short-term interest rate move will be another decrease in the Federal Funds
rate. However, if inflation becomes problematic, further increases in short-term
interest rates could be possible. Investment decisions in the Portfolio will
continue to be dominated by credit quality and liquidity. Although we are
interested in maintaining higher yields, we will not do so by sacrificing the
Portfolio's emphasis on security, quality and liquidity.
 
GROWTH PORTFOLIO
 
    During the six months ended June 30, 1995, the Portfolio underperformed
relative to the Standard & Poor's 500 Index. One factor affecting the
Portfolio's return was its higher weighting in small and mid-cap companies,
which have market capitalizations of less than $1 billion. During most of the
first half of the year, these stocks underperformed versus large-capitalization
stocks, as investors flocked to large-cap issues.
 
    There were no major portfolio shifts during the six months ended June 30,
1995. Although small and mid-cap companies were out of favor during the period,
most posted earnings in line with expectations. There were signs in the second
quarter that investors were rotating into small and mid-cap companies, in search
of future earnings. We continue to believe that these companies have sound
fundamentals and offer attractive prospects for growth. Another area of
concentration continued to be the "Information Highway." While much investor
attention has been focused on who will build the "Highway" into the home, we
have concentrated on the business-oriented market and the variety of investment
opportunities it offers. We also continued our focus on companies that have
managed to reduce expenses, offer quality goods and services and pass on
productivity gains to consumers in the form of low prices. We believe companies
that can deliver products at the lowest price will be profitable in a slow
economic growth environment.
 
    Net assets of the Portfolio totalled $45.2 million as of June 30, 1995. As
of that date, investments consisted of approximately 86.6% common stocks, 0.9%
preferred stocks, 0.6% long-term debt securities, and 11.9% long-term U.S.
government obligations and cash equivalents.
 
GLOBAL GROWTH PORTFOLIO
 
    The six months ended June 30, 1995 were particularly turbulent for
international investors. In addition to the events involving Mexico's currency
and Barings plc, United States dollar weakness continued versus the Deutschemark
and many other European currencies. The result was falling equity markets due to
the expectation of lower corporate earnings and economic growth estimates.
Emerging markets experienced considerable turbulence after the peso devaluation
through April 1995, when a degree of recovery occurred.
 
    Effective March 23, 1995, GE Investment Management Inc. (GEIM), a subsidiary
of GE Investments, became the sub-advisor of the Portfolio. Ralph Layman, who
heads the International Equity Department at GEIM, has been named manager of the
Portfolio. Mr. Layman's investment approach is a bottom-up stock picking style
that focuses on targeting undervalued stocks. He is a long-
 
                                       2
<PAGE>
term investor, and he and his management team look at companies on a three- to
five-year time horizon. They look for globally competitive companies with a
secular growth story, such as new proprietary technology, management changes, or
restructuring. Asset allocation decisions are not made by country or industry.
Mr. Layman is a stock picker first and the country and industry allocation
develops from the stock selection process. However, diversification across
industries and countries is utilized as a risk control measure. He will continue
to look for value in stocks whose share prices have fallen due to market
volatility and sentiment and whose growth fundamentals remain strong.
 
    The new portfolio management team see value in continental Europe, where
stocks are relatively cheap. Europe is pursuing long-term growth through
cost-cutting measures similar to those used by the United States a few years
ago. Their outlook for Mexico going forward is more positive because many
companies have restructured to reduce cost structures and repositioned their
products for export. Additionally, sound opportunities exist in the growing
Pacific region, excluding Japan, which is currently overvalued.
 
    Going forward, Mr. Layman believes these are challenging times in world
equity markets. World growth seems to have slowed and as the operating
environment becomes more competitive, stock picking will become much more
important. Mr. Layman remains committed to his stock picking discipline, ready
to take advantage of investment opportunities offered by volatile markets.
 
    As of June 30, 1995, net assets of the Portfolio totalled $34.7 million.
Investments consisted of approximately 89.9% preferred and common stocks and
8.5% short-term obligations and cash equivalents. By region, approximately 38.6%
of the Portfolio was invested in Europe, 24.1% in Asia, and 21.3% in North
America.
 
GLOBAL INCOME PORTFOLIO
 
    During the six months ended June 30, 1995, the Portfolio benefitted from its
conservative interest rate, currency and duration strategies. (Duration is a
measurement of a portfolio's sensitivity to changes in interest rates.) The
first quarter of 1995 was marked by a particularly weak U.S. dollar, and the
Portfolio benefitted from its currency exposure in Germany, Denmark and the
Netherlands. During the period, the Portfolio maintained a more conservative
exposure to foreign currency risk than many of its competitors. Additionally,
the Portfolio did not participate in the substantial rally in yen-denominated
Japanese bonds during this time. Japanese bonds tend to have low yields and, in
keeping with the Portfolio's income focus, we did not invest in Japanese bonds
or currency.
 
    The Portfolio focused on the short and intermediate sector of the yield
curve in both foreign and domestic bond markets because we believed this sector
offered value and because we did not want to extend portfolio risk with longer
duration bonds. Because emerging market debt exposure was eliminated during the
third quarter of 1994 when the Portfolio's credit quality was upgraded, the
Portfolio avoided the overall decline in emerging market debt after the Mexican
peso devaluation.
 
    Going forward, our outlook remains positive for world fixed income markets.
Slower worldwide growth has provided a benevolent interest rate environment,
with less pressure for tighter monetary policy. Fixed income markets are
generally more liquid than they were in 1994, and this environment should
benefit many of the higher yielding, smaller markets in which the Fund invests.
The large U.S. current account deficit has continued to exert downward pressure
on the dollar and without a substantial improvement in the U.S. trade balance,
we do not foresee an extended dollar rally. However, currency markets are
extremely difficult to predict and often fluctuate more in response to sentiment
than economic fundamentals. As a result, we intend to maintain only moderate
currency exposure in the Portfolio.
 
                                       3

    Net assets of the Portfolio totalled $48.2 million as of June 30, 1995. The
Portfolio's investments consisted of approximately 75.9% long-term debt
securities, 19.8% short-term debt securities, 2.4% repurchase agreements and
1.9% cash and cash equivalents.
 
GOVERNMENT PORTFOLIO
 
    The bulk of the Portfolio's returns during the six months ended June 30,
1995 came from price appreciation resulting from a significant decline in
interest rates. Market psychology became increasingly fixated upon a soft
landing or possibly even a recession, and the prospect that the Fed had finished
its tightening, and was more inclined to ease. From December 1, 1994 through the
end of June, the 30-year U.S. Treasury bond enjoyed close to a 140-basis-point
rally.
 
    As of June 30, 1995, 25.8% of net assets were invested in international
government and Supra-National issues, including the Alberta Province of Canada
and the African Development Bank. Approximately 8% of the Portfolio was invested
in U.S government agency securities. Mortgage pass-through securities of Freddie
Mac constituted 29.7% of the Portfolio, with the remaining 31% of net assets
held in U.S. Treasuries. A more conservative management style has been adopted
for the Fund, emphasizing liquidity and more rigorous analysis of specific
security selections.
 
    Net assets of the Portfolio totalled $18.9 million as of June 30, 1995. The
Portfolio's investments consisted of 94.5% international/government agency
obligations and 5.5% cash and cash equivalents.
 
    In September, shareholders will be asked to review several changes to the
Government Portfolio. These include a new sub-advisory agreement, a change in
investment objective, a change in fundamental investment limitations and a
change in name. If all proposals are approved, the name of the Portfolio will be
changed to "Strategic Fixed Income Portfolio," the current requirement that the
Portfolio invest at least 65% of its total assets in U.S. government securities
will be eliminated and a number of investment policy changes will be
implemented.
 
ASSET ALLOCATION PORTFOLIO
 
    As of June 30, 1995, the Portfolio's asset allocation was 59.5% U.S.
government obligations and 40.5% common stocks, cash and cash equivalents.
During the six month period, Portfolio performance was enhanced by the rally in
both the stock and bond markets.
 
    Performance during the six months ended June 30, 1995 was affected by the
decline in interest rates and the resulting bond market rally. The bond portion
of the Portfolio was positioned in intermediate U.S. Treasury bonds, selected
because they offered maximum yields on a relative return basis with decreased
volatility.
 
    In the equity portion of the Portfolio, we concentrated on growth companies,
which we felt would come back into investor favor in 1995. We also moved to a
higher weighting in technology, seeking out companies like EMC Corp (2.4% of net
assets on June 30, 1995) and Cisco Systems (2.2%). These are examples of
companies where growth rates are relatively high, but the valuations are modest.
We remain committed to investing in stocks that have a combination of good
growth prospects and attractive valuations, which should outperform cyclical
stocks in a slowing economy.
 
    As of June 30, 1995, net assets of the Portfolio totalled $27.1 million.
 
    The Asset Allocation Portfolio is being restructured as of August 14, 1995
to operate as a "balanced fund." It will invest in a combination of equity
securities, investment grade debt obligations
 
                                       4
<PAGE>
and money market instruments. To reflect these changes, the name of this
Portfolio will be changed to "Balanced Portfolio" after the substitution for the
current Balanced Portfolio takes place.
 
DIVIDEND GROWTH PORTFOLIO
 
    The Portfolio performed well during the six months ended June 30, 1995.
While concerns over an impending recession resulted in relative underperformance
in economically sensitive areas during much of the second quarter of 1995,
capital goods and basic materials rebounded recently.
 
    Effective April 3, 1995, Mark A. Tincher, a Managing Director and Chief
Investment Officer of Equity Investments at Mitchell Hutchins Asset Management
Inc., assumed management responsibility for the Portfolio. Mr. Tincher's
management style strives for "value at the right growth." To achieve this, he
relies on traditional valuation measures and earnings-momentum models as well as
his economic outlook. This approach combines both quantitative and fundamental
research. He specifically looks for cheap stocks that should not stay cheap for
long--stocks where he sees signs of change.
 
    Based on the market's focus on the Fed easing and a possible increase in
economic activity, there was some portfolio restructuring during the six months
ended June 30, 1995. Portfolio positions in certain consumer related stocks
(both durables and non-durables) and interest sensitive issues (like utilities)
were reduced. The proceeds were used to overweight positions in the capital
goods area. Going forward, Mr. Tincher believes stocks of cyclical companies
that have done some restructuring in the past five to eight years and/or have
good exposure to sales and earnings growth should continue to reap more of the
benefit of economic growth than defensive stocks.
 
    As of June 30, 1995, the Portfolio's net assets totalled $12.8 million. The
Portfolio's investments consisted of 86.5% equities, 2.4% corporate bonds and
11.1% cash and cash equivalents.
 
    The investment policies of this Portfolio will be changed effective August
14, 1995, to provide the investment manager with more flexibility in selecting
stocks that meet the Portfolio's objectives. The new policy seeks to provide
current income and capital growth. To achieve this, the Portfolio will invest
primarily in dividend-paying equity securities (common and preferred stocks)
believed to have the potential for rapid earnings growth. To better reflect this
change in investment policy, the name of this Portfolio will be changed to
"Growth and Income Portfolio."
 
AGGRESSIVE GROWTH PORTFOLIO
 
    Shares of larger companies continued to lead the equity benchmarks during
the six months ended June 30, 1995. However, signs of a possible rotation of
market leadership from blue-chip issues to the shares of mid-sized and smaller
companies were evident during the second quarter of 1995, as the slowing economy
drove investors to seek out smaller companies that could provide likely pockets
of future outperformance.
 
    As of June 30, 1995, 20.5% of the Portfolio was positioned in technology
stocks, which logged strong returns during the six-month period, on the strength
of gains by electronic instrument and components manufacturers. Semiconductor
manufacturers in particular continued to enjoy strong share price growth. For
example, the Portfolio benefited from its holding in Micron Technology (3.8% of
net assets), which experienced solid growth on the strength of continued
improvement in earnings. Overall market developments have been encouraging. In
any economic environment, however, Nicholas-Applegate Capital Management, the
Portfolio's sub-advisor, will seek to identify companies that are adapting
positively to the environment around them and, as a result, are growing their
earnings and their share prices.
 
                                       5
<PAGE>
    Net assets of the Portfolio totalled $16.6 million as of June 30, 1995. The
Portfolio was 98.2% invested in common stocks and 1.8% invested in cash and cash
equivalents.
 
BALANCED PORTFOLIO
 
    During the six months ended June 30, 1995, the Portfolio performance was
enhanced by the rally in both the stock and bond markets. The Portfolio's net
assets consisted of 75.4% common stocks, 20% fixed income and 4.6% cash and cash
equivalents.
 
    The equity portion of the Portfolio outperformed the overall stock market
during the second quarter of 1995, with performance led by technology and
financial services issues. The Portfolio's performance picked up strength as
each month of the second quarter progressed, suggesting that the relative
valuations of Portfolio companies, which are at the low end of their range,
should begin to move higher as their earnings are recognized, cyclical earnings
come into question and the stock market makes a general transition toward
growth. Provident Investment Council ("PIC"), the Portfolio's sub-advisor,
focuses on companies with superior sales and earnings growth, above average
margins and strong balance sheets. The fixed income portion of the portfolio
benefitted from the bond market's significant rally, which drove long-term
interest rates back to levels not seen since the spring of 1994.
 
    As of June 30, 1995, net assets of the Portfolio totalled $15.5 million.
 
    To improve economies of scale and lower expense ratios for you and other
Milestones contract owners who are invested in either the Balanced Portfolio or
the Asset Allocation Portfolio, the Balanced Portfolio will no longer accept any
funds (i.e., new premiums, add-ons and transfers) effective July 21, 1995. This
action is in anticipation of moving all contract values from the Balanced
Portfolio into the Asset Allocation Portfolio, pursuant to a substitution.
Because this action requires approval from the Securities and Exchange
Commission, it may take several months for this to take place. Effective upon
receipt of regulatory approval, the Sub-Advisory Agreement between Mitchell
Hutchins, the investment adviser and administrator of the Balanced Portfolio,
and PIC will terminate. Until such time as the order is received and the
substitution effected, PIC will continue to provide day-to-day portfolio
management services to the Balanced Portfolio. We will notify contract owners
who are invested in the Balanced Portfolio before this substitution takes place.
 
FIXED INCOME PORTFOLIO
 
    The bond market marched ever higher during the six months ended June 30,
1995, usually outpacing supporting economic fundamentals. Consequently, Wolf,
Webb, Burk and Campbell, Inc. ("WWBC"), the Portfolio's sub-advisor, remained
wary of extending maturities as it perceived the market risk to outweigh the
potential reward. Activity during the period consisted of improving yield in
shorter-term maturities by swapping Treasury bonds for corporate bonds and
increasing the Portfolio's exposure to discount mortgage-backed pass-through
securities.
 
    Net assets of the Portfolio as of June 30, 1995 totalled $9.9 million. The
Portfolio consisted of 25.3% U.S. government and agency obligations, 16.6%
agency mortgage-backed securities, 25.8% high-quality corporate bonds and 32.3%
cash and cash equivalents.
 
                                       6
<PAGE>
    Due to a change in control in the management personnel of WWBC and the
anticipated purchase of WWBC by Consolidated Asset Management, Inc., this
investment firm will no longer be the sub-adviser of the Fixed Income Portfolio.
On July 20, 1995, the Board of Trustees of the PaineWebber Series Trust decided
to remove the sub-adviser. Mitchell Hutchins Asset Management Inc. will provide
all day-to-day investment management for the Fixed Income Portfolio's assets.
Dennis McCauley, Chief Investment Officer, Fixed Income at Mitchell Hutchins,
will be responsible for managing this Portfolio.

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
    PaineWebber Series Trust (the "Fund") is organized under Massachusetts law
by a Declaration of Trust dated November 21, 1986 and is registered with the
Securities and Exchange Commission ("SEC") under the Investment Company Act of
1940, as amended, as an open-end management investment company. The Trustees
have the authority to issue an unlimited number of shares of beneficial
interest, par value $0.001.
 
    As of June 30, 1995, the Fund had ten series of shares available for
investment, each having its own investment objectives and policies: the Money
Market Portfolio, the Growth Portfolio, the Global Growth Portfolio, the Global
Income Portfolio, the Government Portfolio, the Asset Allocation Portfolio, the
Dividend Growth Portfolio, the Aggressive Growth Portfolio, the Balanced
Portfolio and the Fixed Income Portfolio (collectively referred to as the
"Portfolios").
 
    All series of shares are diversified except Global Income Portfolio. Shares
of each series of the Fund are offered only to insurance company separate
accounts which fund certain variable contracts. Shares of each series of the
fund are offered to separate accounts of Paine Webber Life Insurance Company
("PaineWebber Life"). PaineWebber Life is a wholly-owned subsidiary of
PaineWebber Life Holdings Inc., which in turn is a wholly-owned subsidiary of
PaineWebber Group Inc.
 
    Organizational Matters--The costs incurred by the Fund in connection with
its organization and registration of shares of each Portfolio have been deferred
and are being amortized using the straight-line method over the period of
benefit, not to exceed five years, beginning with the commencement of operations
of each Portfolio.
 
    Valuation of Investments--Securities which 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 designated by Mitchell Hutchins Asset
Management Inc. ("Mitchell Hutchins"), a wholly owned subsidiary of PaineWebber
Incorporated ("PaineWebber"), as the primary market for the Growth Portfolio,
Global Growth Portfolio, Global Income Portfolio, Government Portfolio, Asset
Allocation Portfolio and Dividend Growth Portfolio. For the Aggressive Growth
Portfolio, Balanced Portfolio and Fixed Income Portfolio, the securities are
generally valued on the exchange designated by Nicholas-Applegate Capital
Management, Provident Investment Counsel, and Wolf, Webb, Burk & Campbell, Inc.
("Sub-Advisers"), the respective sub-advisers of the Portfolios, as the primary
market. Securities traded in the over-the-counter ("OTC") market and listed on
the National Association of Securities Dealers Automated Quotation System
("NASDAQ") are valued at the last trade price on NASDAQ prior to the time of
valuation; other OTC securities are valued at the last bid price available in
the OTC market prior to the time of valuation. The Money Market Portfolio uses
the amortized cost method, which approximates market value, for valuing its
investments. For the other Portfolios the amortized cost method of valuation is
used with respect only to debt obligations with sixty days or less remaining to
maturity unless the Fund's board of trustees determines that this does not
represent fair value. Securities and assets for which market quotations are
 
                                       62

not readily available are valued at fair value as determined in good faith by or
under the direction of the Fund's board of trustees.
 
    The ability of the issuers of the debt securities held by the Portfolios to
meet their obligations may be affected by economic and political developments,
including those particular to a specific industry, country or region.
 
    All investments quoted in foreign currencies are valued daily in U.S.
dollars on the basis of the foreign currency exchange rate prevailing at the
time such valuation is determined by the Fund's custodians. Foreign currency
exchange rates are generally determined prior to the close of the New York Stock
Exchange ("NYSE"). Occasionally, events affecting the value of foreign
investments and such exchange rates occur between the time at which they are
determined and the close of the NYSE, which will not be reflected in a
computation of the Portfolios' net asset value. If events materially affecting
the value of such investments or currency exchange rates occurred during such
time period, the securities are valued at their fair value as determined in good
faith by or under the direction of the Fund's board of trustees.
 
    Investment Transactions and Investment Income--Investment transactions are
accounted for on the trade date. Realized gains and losses on sales of
investments and foreign security and foreign exchange transactions are
calculated using the identified cost basis. Dividend income and other
distributions are recorded on the ex-dividend date ("ex-date") (except for
certain dividends from foreign securities that are recorded as soon after the
ex-date as the respective Portfolio becomes aware of such dividends). Interest
income is recorded on an accrual basis. Discounts are accreted as adjustments to
interest income and the identified cost of investments.
 
    Foreign Currency Translation--The books and records of the Global Growth
Portfolio and Global Income Portfolio are maintained in U.S. dollars as follows:
(1) the foreign currency market value of investment securities and other assets
and liabilities stated in foreign currencies are translated at the exchange
rates prevailing at the end of the period; and (2) purchases, sales, income and
expenses are translated at the rate of exchange prevailing on the respective
dates of such transactions. The resulting exchange gains and losses are included
in the Statement of Operations.
 
    The Global Growth Portfolio and Global Income Portfolio do not generally
isolate the effect of fluctuations in foreign exchange rates from the effects of
fluctuations in the market price of investment securities. However, these
Portfolios do isolate the effect of fluctuations in foreign exchange rates when
determining the realized gain or loss upon the sale or maturity of foreign
currency-denominated debt obligations pursuant to federal income tax
regulations; such amount is categorized as foreign exchange gain or loss for
both financial reporting and income tax purposes.
 
    Forward Foreign Currency Contracts--The Global Growth, Global Income and
Government Portfolios may enter into forward foreign currency exchange contracts
("forward contracts") in connection with planned purchases or sales of
securities to hedge the U.S. dollar value of portfolio securities denominated in
a particular currency. These portfolios may also engage in cross-hedging by
using forward contracts in one currency to hedge fluctuations in the value of
securities denominated in a

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

different currency if Mitchell Hutchins anticipates that there will be a
correlation between the two currencies. Forward contracts may also be used to
shift a Portfolio's exposure to foreign currency fluctuations from one country
to another.
 
    These Portfolios have no specific limitation on the percentage of assets
which may be committed to such contracts; however, the value of all forward
contracts will not exceed the total market value of the Portfolio's total
assets. These Portfolios may enter into forward contracts or maintain a net
exposure to forward 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 positions being hedged by such contracts or (2) the
Portfolios maintain cash, U.S. government securities or liquid, high-grade debt
securities in a segregated account in an amount not less than the value of the
Portfolio's total assets committed to the consummation of the forward contracts
and not covered as provided in (1) above, as marked to market daily.
 
    Risks may arise upon entering into forward contracts from the potential
inability of counterparties to meet the terms of their contracts and from
unanticipated movements in the value of foreign currencies relative to the U.S.
dollar.
 
    Fluctuations in the value of forward contracts are recorded for book
purposes as unrealized gains or losses by the Portfolios. Realized gains and
losses include net gains or losses recognized by the Portfolio on contracts
which have matured.
 
    Option Writing--When the Portfolios write a call or a put option, an amount
equal to the premium received by the Portfolios is included in the Portfolios'
Statement of Assets and Liabilities as an asset and as an equivalent liability.
The amount of the liability is subsequently marked-to-market to reflect the
current market value of the option written. If an option which the Portfolios
have written either expires on its stipulated expiration date or the Portfolios
enter into a closing purchase transaction, the Portfolios realize a gain (or
loss if the cost of a closing purchase transaction exceeds the premium received
when the option was written) without regard to any unrealized gain or loss on
the underlying security, and the liability related to such option is
extinguished. If a call option which the Portfolios have written is exercised,
the Portfolios realize a capital gain or loss (long-term or short-term,
depending on the holding period of the underlying security) from the sale of the
underlying security and the proceeds from the sale are increased by the premium
originally received. If a put option which the Portfolios have written is
exercised, the amount of the premium originally received reduces the cost of the
security which the Portfolios purchase upon exercise of the option.
 
    Repurchase Agreements--Each Portfolio's custodian takes possession of the
collateral pledged for investments in repurchase agreements. The underlying
collateral is valued daily on a mark-to-market basis to ensure that the value,
including accrued interest, is at least equal to the repurchase price. In the
event of default of the obligation to repurchase, the Portfolios have the right
to liquidate the collateral and apply the proceeds in satisfaction of the
obligations. Under certain circumstances, in the event of default or bankruptcy
by the other party to the agreement, realization and/or retention of the
collateral may be subject to legal proceedings.

--------------------------------------------------------------------------------
 
    Each Portfolio occasionally participates in joint repurchase agreement
transactions with other Funds managed by Mitchell Hutchins. At June 30, 1995 the
Asset Allocation, Dividend Growth, Government, Growth, Balanced and Fixed Income
Portfolios have a proportionate interest in a joint transaction outstanding with
State Street Bank & Trust Co. Also at June 30, 1995, the Global Growth and
Global Income Portfolios have a proportionate interest in a joint transaction
outstanding with Brown Brothers Harriman & Co.
 
    Reverse Repurchase Agreements--Each Portfolio may enter into reverse
repurchase agreements with banks and broker-dealers up to an aggregate value of
not more than 5% of its total assets (10% of total assets for Global Income and
Balanced Portfolios). At June 30, 1995, the Portfolios had no reverse repurchase
agreements outstanding.
 
    Federal Tax Status--Each of the Portfolios intends to distribute all of
their taxable income and to comply with the other requirements of the Internal
Revenue Code applicable to regulated investment companies. Accordingly, no
provision for federal income taxes is required.
 
    Dividends and Distributions to Shareholders--Dividends and distributions to
shareholders are recorded on the ex-dividend date. The amount of dividends and
distributions are determined in accordance with federal income tax regulations
which may differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.
 
INVESTMENT ADVISER AND ADMINISTRATOR
 
    The Fund's board of trustees has approved an investment advisory and
administration contract ("Advisory Contract") with Mitchell Hutchins, under
which Mitchell Hutchins serves as investment

(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.
 
 * Annualized.
 
 ** During certain periods presented above, Mitchell Hutchins agreed to
    reimburse the Portfolio for all 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%, respectively, for the year ended December 31, 1990.
