Dear Contract Owner,
 
    We are pleased to present the Semiannual Report for Milestones, offered
exclusively through PaineWebber. This report contains important information
about the PaineWebber Series Trust, including financial statements for the six
months ended June 30, 1996. As you know, the PaineWebber Life Variable Annuity
account holds shares of the PaineWebber Series Trust to fund the Milestones
Variable Annuity.
 
INVESTMENT OVERVIEW--DOMESTIC
 
    By the end of 1995, most investors were convinced that the Federal Reserve
Board had achieved a "soft landing" for the economy, which led to a general
consensus that the Fed would act again to cut short-term interest rates.
Sentiment changed in early March, however, in response to government reports
showing higher-than-expected economic growth; there was a sharp drop in bond
prices which caused volatility in the stock market. Despite this volatility, the
stock market, as measured by the Standard & Poor's 500 Index, advanced 10.09%
through June 30, 1996. Several factors helped move stocks higher, including an
overall positive environment for corporate earnings and profit growth as well as
strong cash flows into equity mutual funds.
 
    After exceptional performance during most of 1995, the first half of the
year was difficult for fixed income investors. Accelerating economic growth,
reflected in strong employment, retail sales and investment spending numbers, as
well as a surprisingly robust housing sector, combined to change market
expectations from the Fed easing to the Fed tightening. The 30-year U.S.
Treasury bond, a benchmark of bond market performance, was yielding 5.95% on
December 29, 1995 and 6.87% on June 28, 1996. When bond yields increase, bond
prices decrease. Meanwhile, the Federal Reserve's Open Market Committee decided
to keep monetary policy unchanged at the March, May and July 1996 meetings. The
Fed's decision to hold rates steady suggested that officials did not foresee a
recession or accelerating inflation.
 
INVESTMENT OVERVIEW--GLOBAL
 
    World bond markets produced mixed returns during the six-month period, but
the stronger dollar eroded favorable returns in many markets. The Salomon
Brothers World Government Bond Index (currency hedged) was up 1.71% for the
period, while the unhedged Index declined 1.48%. European governments continued
to progress toward the goal of monetary union ("EMU"). While we cannot say with
certainty that monetary union will be achieved by the target date of January 1,
1999, the probability of its occurrence continues to grow. Efforts toward EMU
create a positive environment for European bonds because of the strict inflation
and fiscal targets which its members must achieve.
 
    After taking a back seat to the U.S. stock market during 1995, overseas
markets rose during the first half of the year, with many markets outperforming
the U.S. Notable performers included France, Hong Kong, Mexico, and the
Netherlands. Valuations of global stocks are attractive, particularly in Europe.
Many of these companies have begun to restructure their operations, similar to
U.S. companies several years ago. In addition, inflation is tame on the
Continent, with the possibility of lower rates in several European markets.
While European markets generally performed well, Asian markets, with the
exception of Hong Kong, reacted to fears of higher U.S. interest rates and
tended to be weak during the period.
 
MONEY MARKET PORTFOLIO
 
    During the first half of 1996, short-term interest rates began to decrease
in the six-month to one-year sector, steepening the short end of the yield
curve. The discounted 30-day commercial paper rate also decreased to
approximately 5.35% on June 30, 1996. It now appears that the Federal Reserve
Board will not raise rates until after the 1996 presidential election. In
anticipation of a stable to lower
 
                                       1
<PAGE>
interest rate environment, the Portfolio's weighted average maturity was
increased during the period. The Portfolio will maintain its current position
until further economic data is released.
 
    For the seven days ended June 30, 1996, the Portfolio's current yield was
4.29%. On June 30, 1996, the Portfolio's weighted average maturity was 67 days.
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 first half of 1996, the Portfolio continued to gain ground as
investors broadened their interest toward growth stocks. It has been our
contention that the equity markets have been driven by demand for stocks coming
from several sources, but in particular, from unprecedented inflows into equity
funds from 401(k) plans and other retirement sources. We expect this trend to
continue, providing continuing demand for stocks over time.
 
    An ongoing industry trend in the current economic environment has been
consolidation. Specifically, one company acquires another and the end result is
a larger company, which can produce economies of scale and improve profit
margins. Examples of this have occurred within several different sectors in
which the Portfolio invests. HFS (3.0% of Portfolio assets on June 30, 1996), is
the largest franchisor of popularly priced hotel rooms. Its franchisees own and
operate Days Inn, Howard Johnson, Ramada and Super 8 motels. The company
aggressively expanded beyond its traditional motel franchise business with the
acquisition of three real estate brokerage firms--Century 21, ERA and Coldwell
Banker. HFS is also participating in negotiations to acquire Avis Rent-A-Car. In
the medical providers sector, Phycor (2.3%) is acquiring physician practice
organizations in several specialities and then consolidating their record
keeping and administrative functions.
 
    We continue to believe that the "Information Highway" is one of the
strongest worldwide secular growth areas. We are particularly interested in
competitive access providers, those companies that bypass local telephone
companies to provide both long distance and soon-to-be local phone service as
well as special services to office buildings utilizing "networks" of optical
fiber. Examples include MFS Communications (1.4%), Teleport Communications Group
(0.6%), Brooks Fiber Properties (0.4%) and Intelcom Group (2.2%).
 
    Over long periods of time, stock prices reflect earnings growth. Therefore,
to achieve higher returns in a period of slow economic growth, the Portfolio is
pursuing investments in companies with above-average earnings growth potential.
 
    Net assets of the Portfolio totalled $44.5 million as of June 30, 1996. As
of that date, investments consisted of approximately 90.6% common stocks, 0.9%
preferred stocks, 2.2% convertible bonds and 6.3% short-term U.S. government
obligations and cash equivalents.
 
GLOBAL GROWTH PORTFOLIO
 
    As we mentioned in our last report, 1995 will be remembered for the strong
performance of the U.S. stock market, which outdistanced most overseas markets.
While the U.S. enjoyed a record stock market ride, the rest of the world's
markets positioned themselves for a recovery. Although the bull market in the
U.S. continued during the first half of the year, global stock markets rose as
well, with European shares performing particularly well.
 
    Overseas, the Portfolio manager, Ralph Layman of GE Investment Management
Incorporated ("GEIM"), the Portfolio's sub-adviser, continues to be attracted to
Europe. The European managers GEIM has visited have started to restructure their
operations, a process begun in the U.S. several years ago. Also, inflation is
tame on the Continent, with the possibility of lower rates in several markets.
In Asia, recent weakness has given GEIM the opportunity to add some new names to
the Portfolio. They continue to like the region for its relatively high growth
rates and reasonable valuations.
 
                                       2
<PAGE>
    Equity markets, particularly the U.S., have been driven by low interest
rates, sustained economic growth and strong flows into equity mutual funds.
GEIM's investment process, which targets growth stocks at a reasonable price,
was out of favor during most of the six-month period. GEIM tends to look for
companies which have value overlooked by the market and a catalyst to unlock
that value over a 3-5 year time horizon. These stocks occasionally suffer due to
disappointments, and the market may overlook their potential during strong
bull-market runs. Money across the globe has been chasing stocks that have risen
the most (momentum stocks) and are the most liquid, not necessarily those
offering the best value. GEIM believes its investment process is sound, and will
continue to invest in companies that have good value characteristics relative to
their growth rate.
 
    As of June 30, 1996, net assets of the Portfolio totalled $26.8 million.
Investments consisted of approximately 99.4% preferred and common stocks and
0.6% short-term obligations and cash equivalents. By region, approximately 44.3%
of the Portfolio was invested in Europe, 27.1% in North America, and 20.7% in
Asia.
 
GLOBAL INCOME PORTFOLIO
 
    We wrote in last December's Annual Report that relative values appeared
better in European, Australian and Canadian government bonds than in U.S.
Treasuries or Japanese government bonds. During the six months ended June 30,
1996, these markets generally rose, while U.S. Treasuries and Japanese
government bonds depreciated. However, the stronger dollar eroded favorable
returns in many foreign markets.
 
    During the six months ended June 30, 1996, the Portfolio's currency hedging
strategy mitigated the impact of currency losses on the Portfolio's non-dollar
holdings. In addition, the Portfolio generally maintained a low duration during
the period--usually under 3 years--as well as a significant cash position. While
this duration strategy dampened the impact of the strong appreciation in the
bond markets at the end of 1995, it also helped to protect the Portfolio's net
asset value when markets sold-off in February 1996.
 
    During the six months, we left the Portfolio's broad market allocations
unchanged. We maintained approximately 36.8% of the Portfolio's net assets in
Europe, but moved holdings among countries on several occasions. For instance,
we shifted assets from Spanish bonds to Italian bonds to capture the
appreciation of the lira against other European currencies. We took profits in
Dutch bonds to take advantage of attractive yields in Denmark. We continue to
hold approximately 42.3% of the Portfolio's assets in the U.S., primarily in
two-year maturity Treasury bonds as a protective strategy, although lately we
have begun to extend these maturities.
 
    We maintain roughly 18.4% of the Portfolio's assets in a combination of
Canadian, Australian and New Zealand bonds. As Canadian yields narrowed to U.S.
yields, we reallocated some of the Fund's assets into Australian bonds where
yield premiums over U.S. Treasuries are more attractive. We continue to believe
Australian bonds represent an attractive alternative to U.S. bonds. The newly
elected government in Australia has promised to reduce the Federal deficit--a
move which would also help to reduce the country's chronic current account
deficit. A reduction of the "twin deficits" would be positive for the currency
and bond markets. As Australia is a primary exporter to Asian Pacific countries,
its current account and currency should also benefit from any acceleration in
Japanese growth during the next twelve months.
 
    Net assets of the Portfolio totalled $29.3 million as of June 30, 1996. The
Portfolio's investments consisted of approximately 73.1% long-term debt
securities, 23.8% short-term debt securities and 3.1% repurchase agreements and
cash equivalents. By region, approximately 49.0% of the portfolio was invested
in North America, 36.8% in Europe and 14.2% in Australia and New Zealand.

STRATEGIC FIXED INCOME PORTFOLIO
 
    As yields moved higher from year-end levels, the bond market continued to be
negatively impacted by stronger-than-expected economic data during the first
half of 1996. Employment growth, strong consumer and capital spending, and a
robust housing sector have combined to create an economy that is growing at a
faster-than-expected rate. This has prompted fears that the Federal Reserve
Board will feel compelled to tighten credit, perhaps as early as this August.
While the Portfolio outperformed its benchmark, the Lehman Brothers
Government/Corporate Bond Index, the impact of rising interest rates caused
negative absolute returns.
 
    During the period, mortgage securities outperformed Treasury instruments, as
market volatility and prepayments speeds declined. The extra yield associated
with mortgage bonds can be thought of as compensation for volatility and
prepayment risk. The Portfolio benefitted from specific holdings such as certain
CMOs and adjustable rate mortgages (ARMs), which added to relative returns.
Other holdings that helped performance were U.S. Treasury 10- and 30-year bond
futures, which added incremental yield over actual bonds due to effective
investment of the cash equivalents which back the futures contracts. During the
first quarter, currency-hedged allocations to the German bond market
substantially outperformed all U.S. sectors.
 
    In May, Pacific Investment Management Company ("PIMCO"), the Portfolio's
sub-adviser, reaffirmed its secular forecast of 5-7% for long-term interest
rates. Given that 30-year Treasury rates now exceed the 7% level, PIMCO is very
optimistic about the prospects for rate declines. While growth has clearly risen
during the first part of 1996, they remain confident that the U.S. economy will
grow less quickly than market expectations. This, together with a very benign
inflation outlook, creates a backdrop for attractive returns for the latter part
of the year. As a result, PIMCO will continue to position the Portfolio with a
longer average maturity than the benchmark index.
 
    Security selection will remain concentrated in the mortgage sector, with
ARMs and Z-tranche CMOs the areas where PIMCO sees the most relative value.
Continued declines in market volatility should allow significant outperformance
of Treasuries given mortgage yield advantages. When PIMCO invests in Treasuries,
it will be through Treasury bond futures contracts, due to their additional
yield as a result of investing the cash equivalents which backs these contracts.
 
    Net assets of the Portfolio totalled $12.1 million as of June 30, 1996.
 
BALANCED PORTFOLIO
 
    As of June 30, 1996, the Portfolio's asset allocation was 58.4% common
stocks, 1.5% preferred stocks, 23.7% U.S. long-term government and agency
obligations, 10.7% long-term debt securities and 5.7% cash and cash equivalents.
 
    The Portfolio employs a disciplined, model-based approach to calculate
expected returns for U.S. stocks, bonds and cash. Based on consensus
expectations for key economic variables such as interest rates, profit growth
and inflation--as well as fundamental valuation techniques--the Portfolio seeks
to determine whether the expected return from stocks is sufficient to offset the
additional risk when compared to bonds and "risk-free" cash investments.
Portfolio assets are repositioned based on the model, with a minimum of 25% of
net assets in bonds (including cash equivalents) at all times.
 
    During the six months ended June 30, 1996, the stock market experienced
significant volatility, reflecting conflicting views that the economy was headed
for either a soft landing or more vigorous growth. Interest rates moved up, in
anticipation of the Fed increasing short-term rates, and the bond market
weakened. Our analysis suggests that the deterioration in bond prices was
overdone and that the fixed income market has become more attractive. As a
result, the Portfolio's assets were reallocated during the six-month period, to
align with our longer-term, neutral weighting of 60% equities, 40% fixed income.
 
                                       4
<PAGE>
    In the near term, we expect to maintain the Portfolio's neutral asset
allocation. An overweighting in stocks would require further reductions in
short-term interest rates and inflation, and/or an improved outlook for
corporate earnings. An underweighting in stocks would be caused by a more
restrictive monetary policy, rising inflation and/or the deterioration in the
outlook for earnings growth that would be characteristic of an economic forecast
calling for a recession in 1997. Even if the economy continues to perform
moderately well, the outlook for earnings could deteriorate if an increasing
percentage of gross sales revenues goes for wage payment, as price competition
precludes corporations from passing along higher wages. At the current time,
none of these events appear particularly likely.
 
    An overweighting in bonds would require further reductions in inflationary
expectations and/or further easing by the Fed. Overweighting in bonds would also
obviously arise from a recessionary economic environment. Underweighting in
bonds would be called for if the economic strength evidenced in the second
quarter were to continue, generating fears of accelerating inflation.
 
    As of June 30, 1996, net assets of the Portfolio totalled $33.7 million.
 
GROWTH AND INCOME PORTFOLIO
 
    Expectations have changed dramatically since the start of 1996, as the
economy began to show signs of strength in contrast to the previously expected
weakness. As a result, some earnings estimates, especially in technology and
capital goods, are rapidly deteriorating. Given this environment, we have sought
greater diversification within the Portfolio. In particular, we view mid- to
smaller-cap issues attractive due to modest valuations relative to large-caps,
as well as more rapid growth prospects. Within this sector we're finding select
technology companies, as well as certain consumer cyclicals like auto
parts-related industries, attractive.
 
    Going forward, we expect to maintain the Portfolio's weightings in
financials, healthcare and technology. The financial sector has recently lagged
the overall market due to recent bond market difficulties. However, we continue
to overweight select regional banks and insurance companies based on relatively
low valuations, potential industry consolidation and a belief that interest
rates will moderate toward year end. Technology stocks may experience near-term
volatility; thus we have taken a cautious stance and intend to focus on larger,
more liquid companies.
 
    Looking ahead, stock market performance will reflect both interest rate
movements and earnings revisions. The recent rise in interest rates is expected
to dampen economic growth. As a result, the potential for changes in earnings
expectations should play a more significant role in valuation. In an environment
of moderate economic expectations, the opportunity for selective positive
earnings surprises remains. We remain confident that our investment process will
continue to uncover advantageous investment opportunities.
 
    As of June 30, 1996, the Portfolio's net assets totalled $16.3 million. The
Portfolio's investments consisted of 90.7% equities, 2.8% corporate bonds and
6.5% cash and cash equivalents.
 
AGGRESSIVE GROWTH PORTFOLIO
 
    So far this year, investors have been focusing their attention on solid
earnings growth, with growth companies outperforming value companies. Some of
the top performing sectors during the first two quarters included retail, based
on continued strong sales; utilities, which had a strong June as the broad
market weakened; and consumer non-durables. Technology stocks also did well
despite a difficult June, but have recently come under price pressure. Some of
the bottom performing sectors included consumer durables and raw materials--both
sectors were affected by rising interest rates and inflation uncertainty.
 
    Nicholas-Applegate Capital Management, the Portfolio's sub-adviser, focuses
on identifying dynamic growth companies managing change and growing their
earnings and businesses today, not just the typical growers of the past. Their
investment approach systematically evaluates 4,000 domestic
 
                                       5
<PAGE>
companies based upon their earnings growth, sustainability of earnings growth
and strong relative price strength, in order to identify attractive growth
issues. As a result, at the end of June, the Portfolio continued to have a
significant technology weighting. Several semi-conductor companies were sold,
however, and several software issues were purchased based upon their strong
earnings growth. Other areas with growth opportunities are healthcare services
and consumer services. The Portfolio remained close to fully invested during the
six-month period.
 
    Net assets of the Portfolio totalled $19.9 million as of June 30, 1996. The
Portfolio was 98.3% invested in common stocks and 1.7% invested in cash and cash
equivalents.
 
HIGH GRADE FIXED INCOME PORTFOLIO
 
    With strong economic fundamentals and a neutral-to-restrictive Federal
Reserve as backdrops, the bond market continued its price decline during the
first half of 1996. Latent fears of future inflation, based on above-trend
economic growth, pushed the yield on the 30-year Treasury bond up over 0.50% to
a high of 7.19% in mid-June. During the period, we repositioned the Portfolio in
a more defensive nature. Duration (interest rate sensitivity) was slightly
reduced and the Portfolio's mortgage-backed securities position was increased.
In our view, mortgages remain cheap on a relative value basis. In light of
historically tight corporate spreads, we have kept a neutral allocation to that
sector.
 
    Moving forward, our view is that the economy will continue to expand, but
moderately. We forecast that inflation will remain subdued, creating a stable
environment for interest rates. Also, the over-extension of consumers would
suggest a slowing down in future spending. However, the near-term picture is not
so positive. Monetary tightening has become a question of when, not if. Current
economic fundamentals suggest higher rates. Based on this, market psychology
remains bearish in the short run. Therefore, due to these near-term bearish
fundamentals and technicals, we remain defensive. However, as we see evidence
confirming our longer-term outlook, we will lengthen duration to capture the
next downward trend in interest rates.
 
    Net assets of the Portfolio as of June 30, 1996 totalled $9.0 million. The
Portfolio consisted
of 42.8% high-quality corporate bonds, 34.1% U.S. government and agency
obligations, 6.4% agency pass-through securities, 6.1% collateralized mortgage
obligations and 10.6% cash and cash equivalents.
 
    The first half of 1996 was marked by volatility in most financial markets.

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 under the Investment Company Act of 1940, as
amended, as an open-end management investment company. The Fund's board of
trustees have the authority to issue an unlimited number of shares of beneficial
interest, par value $0.001.
 
    As of June 30, 1996, the Fund had nine 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 Strategic Fixed Income Portfolio; the Balanced Portfolio,
the Growth and Income Portfolio; the Aggressive Growth Portfolio and the High
Grade Fixed Income Portfolio (collectively referred to as the "Portfolios"). At
the close of business on January 26, 1996, shares of the former Asset Allocation
Portfolio were substituted for all shares of the former Balanced Portfolio, the
sub-advisory agreement between Mitchell Hutchins and Provident Investment
Counsel, Inc. was terminated, and the former Asset Allocation Portfolio was
renamed the Balanced Portfolio.
 
    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 PaineWebber 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 Growth and Income
Portfolio in connection with its organization and registration of shares of the
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 the 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"), or by the applicable sub-adviser, as the primary
market for each Portfolio. Securities traded in the over-the-counter ("OTC")
market and listed on The Nasdaq Stock Market, Inc. ("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 amortized cost method, which approximates market value, is
used to value 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 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.

    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 values. If events materially affecting
the value of such investments or currency exchange rates occur 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
recorded on the trade date. Realized gains and losses from investment
transactions are calculated on the identified cost basis. Dividend income is
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
Portfolios become 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 Portfolios 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 Portfolios 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, the 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--Certain 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 or the applicable sub-adviser anticipates that there is 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 a Portfolio's total assets.
The Portfolios may not enter into forward contracts unless (1) 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 or
liquid 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.
 
    Futures Contracts--Upon entering into a financial futures contract, a Fund
is required to pledge to a broker an amount of cash and/or U.S. Government
securities equal to a certain percentage of the contract amount. This amount is
known as the "initial margin." Subsequent payments, known as "variation margin"
are made or received by the Fund each day, depending on the daily fluctuations
in the value of the underlying financial futures contracts. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss until the financial futures contract is closed, at which
time the net gain or loss is reclassified to realized.
 
    The Strategic Fixed Income Fund primarily used financial futures contracts
for hedging purposes as well as to manage the average duration of a Fund's
portfolio. However, imperfect correlations between futures contracts and the
portfolio securities being hedged, or market disruptions, do not normally permit
full control of these risks at all times.
 
    Option Writing--When a Portfolio writes a call or a put option, an amount
equal to the premium received by the Portfolio is included in the Portfolio's
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 Portfolio has
written either expires on its stipulated expiration date or the Portfolio enters
into a closing purchase transaction, the Portfolio realizes 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 Portfolio has written is exercised, the Portfolio
realizes 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 Portfolio has written is exercised, the
amount of the premium originally received reduces the cost of the security which
the Portfolio purchases 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.
 
    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, 1996, the Portfolios had no reverse repurchase
agreements outstanding.
 
    Dividends and Distributions--Dividends and distributions to shareholders are
recorded on the ex-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.
 
CONCENTRATION OF RISK
 
    Investing in securities of foreign issuers and currency transactions may
involve certain considerations and risks not typically associated with
investments in the United States. These risks include revaluation of currencies,
adverse fluctuations in foreign currency values and possible adverse political,
social and economic developments, including those particular to a specific
industry, country or region, which could cause the securities and their markets
to be less liquid and prices more volatile than those of comparable U.S.
companies and U.S. government securities. These risks are greater with respect
to securities of issuers located in emerging market countries in which certain
of the Portfolios are authorized to invest. The ability of the issuers of debt
securities held by the Portfolios to meet their obligations may be affected by
economic and political developments particular to a specific industry, country
or region.

    reimburse the Portfolio for a portion of its operating expenses and waived

(1) Total investment return is calculated assuming a $1,000 investment on the
    first day of each period reported, reinvestment of all dividends and
    distributions at net asset value on the payable dates and a sale at net
    asset value on the last day of each period reported. The figures do not
    include additional contract level charges; results would be lower if such
    charges were included. Total investment return for periods of less than one
    year have not been annualized.

 * Annualized
 
 ** During the period ended December 31, 1993, Mitchell Hutchins agreed to
    reimburse the Portfolio for all of its operating expenses and waived all of
    its advisory fees. 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 (loss) to average net assets would have been 23.52%
    and (19.62)%, respectively.
 
(1) Total investment return is calculated assuming a $1,000 investment on the
    first day of each period reported, reinvestment of all dividends and
    distributions at net asset value on the payable dates and a sale at net
    asset value on the last day of each period reported. The figures do not
    include additional contract level charges; results would be lower if such
    charges were included. Total investment return for periods of less than one
    year have not been annualized.
