The Fund:                       PaineWebber  Tactical  Allocation  Fund  ('Fund') is  a  diversified  series  of Mitchell
                                Hutchins/Kidder, Peabody Investment  Trust ('Trust'), an  open-end management  investment
                                company.
Investment Objective and        Total  return, consisting of long-term capital appreciation and current income; utilizing
  Policies:                     a systematic investment strategy that actively  allocates the Fund's assets among  common
                                stocks, U.S. Treasury Notes and U.S. Treasury Bills.
Total Net Assets at             $55.8 million
  November 30, 1995:
Investment Adviser and          Mitchell  Hutchins  Asset  Management  Inc. ('Mitchell  Hutchins'),  an  asset management
  Administrator:                subsidiary of  PaineWebber  Incorporated  ('PaineWebber' or  'PW'),  manages  over  $44.7
                                billion in assets. See 'Management.'
Purchases:                      Shares  of  beneficial interest  are available  exclusively  through PaineWebber  and its
                                correspondent firms  for  investors  who  are  clients  of  PaineWebber  or  those  firms
                                ('PaineWebber  clients') and, for other investors, through PFPC Inc., the Fund's transfer
                                agent ('Transfer Agent').
Flexible Pricing System:        Investors may select  Class A, Class  B or Class  C shares, each  with a public  offering
                                price  that reflects  different sales charges  and expense levels.  See 'Flexible Pricing
                                System,' 'Purchases,' 'Redemptions' and 'Conversion of Class B Shares.'
Class A Shares                  Offered at net  asset value  plus any  applicable sales charge  (maximum is  4.5% of  the
                                public offering price).
Class B Shares                  Offered  at  net  asset  value (a  maximum  contingent  deferred sales  charge  of  5% of
                                redemption proceeds is imposed on  certain redemptions made within  six years of date  of
                                purchase).  Class B  shares automatically  convert into Class  A shares  (which pay lower
                                ongoing expenses) approximately six  years after purchase. Such  Class B shares were  not
                                offered prior to January 1, 1996.
Class C Shares                  Offered  at net  asset value without  an initial  or contingent deferred  sales charge (a
                                contingent deferred  sales charge  of 1%  of redemption  proceeds is  imposed on  certain
                                redemptions made within one year of purchase). Class C shares pay higher ongoing expenses
                                than  Class A shares and do  not convert into another Class.  Prior to November 10, 1995,
                                these Class C shares were called 'Class B' shares.
Exchanges:                      Shares may be exchanged for shares of the corresponding Class of most PaineWebber  mutual
                                funds.
Redemptions:                    PaineWebber  clients  may  redeem  through PaineWebber;  other  shareholders  must redeem
                                through the Transfer Agent.
Dividends:                      Declared and paid annually; net capital gain,  if any, also is distributed annually.  See
                                'Dividends, Distributions and Taxes.'
Reinvestment:                   All dividends and capital gain distributions are paid in Fund shares of the same Class at
                                net asset value unless the shareholder has requested cash.
Minimum Purchase:               $1,000 for first purchase; $100 for subsequent purchases.

Other Features:
  Class A Shares                Automatic investment plan   Quantity discounts on initial sales charge
                                Systematic withdrawal plan  365-day reinstatement privilege

 PAINEWEBBER   TACTICAL ALLOCATION FUND

                               PROSPECTUS SUMMARY
                                  (Continued)
- --------------------------------------------------------------------------------
 
WHO SHOULD INVEST. The Fund follows a systematic investment strategy that
actively allocates the Fund's assets among common stocks, U.S. Treasury Notes
and U.S. Treasury Bills and is designed for investors who are seeking total
return, consisting of long-term capital appreciation and current income. The
Fund's risk factors are summarized below and are described in more detail under
'Investment Objective and Policies -- Risk Factors and Special Considerations.'
While the Fund is not intended to provide a complete or balanced investment
program, it can serve as one component of an investor's long-term program to
accumulate assets, for instance, for retirement, college tuition or other major
goals.
 

ASSET ALLOCATION STRATEGY. The Fund follows an asset allocation strategy
involving investing among the following asset categories ('Segments'): (1) the
common stocks primarily included in the Standard & Poor's 500 Composite Stock
Price Index (the 'S&P 500 Index') and derivative instruments relating thereto
(the 'Stock Segment'), the performance of which, before deduction of operating
expenses, is intended to replicate as closely as possible the aggregate price
and yield performance of the S&P 500 Index; (2) 30-day U.S. Treasury Bills (the
'Cash Segment'); and (3) five-year U.S. Treasury Notes and derivative
instruments relating thereto (the 'Note Segment'). Asset allocations are
determined by Mitchell Hutchins based on relative rates of return among the
Segments. See 'Investment Objective and Policies.' The Fund's asset allocation
strategy is designed to afford investors the opportunity to seek total return
during all economic and financial market cycles, with a degree of volatility
lower than that of the equity market, utilizing a systematic, cost effective
asset allocation strategy. The Fund allocates its assets among the Segments in
accordance with an Asset Allocation Model (the 'Allocation Model') utilized by
Mitchell Hutchins. See 'Investment Objective and Policies -- Asset Allocation
Strategy.'

 
RISK FACTORS. There can be no assurance that the Fund will achieve its
investment objective, and the Fund's net asset value will fluctuate based upon
changes in the value of its portfolio securities.

Although the Fund will seek long term total return consisting of both capital
appreciation and current income, the Fund may not achieve as high a level of
either capital appreciation or current income as a fund that has only one of
those objectives as its primary objective. Because the benefits of the
Allocation Model, on which the Fund's investment decisions are based, are
expected to be realized only if the recommendations are followed over several
market cycles, the Fund is intended to be a long term investment vehicle and is
not designed to provide investors with a means of speculating on short term
market movements. The investment results of the Fund (and the Stock Segment) at
any time may be greater or less than those of the S&P 500 Index. Deviations from
the performance of the S&P 500 Index may result from the proportion of assets
then allocated to the Stock Segment in accordance with the Allocation Model,
purchases and redemptions of shares of the Fund that occur daily, as well as
from brokerage and other expenses borne by the Fund. Thus, no assurance can be
given that the Fund's investment objective will be achieved. The Fund may also
be subject to certain risks in using investment techniques and strategies such
as entering into futures contracts and options on futures contracts, entering
into transactions involving options on stock indexes, purchasing securities on a
when-issued or delayed delivery basis and entering into repurchase agreements.
See 'Investment Objective and Policies -- Risk Factors and Special
Considerations' at page 13 of this Prospectus.

(1) Sales charge waivers are available for Class A and Class B shares and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase; the charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    'Purchases.'
 
(2) Purchases of Class A shares of $1 million or more are not subject to a sales
    charge. If shares are redeemed within one year of purchase, a contingent
    deferred sales charge of 1% will be applied to the redemption. See
    'Purchases.'
 
(3) If Class C shares are redeemed within one year of purchase, a contingent
    deferred sales charge of 1% will be applied to the redemption. See
    'Purchases.'
 
(4) See 'Management' for additional information. All expenses, except for Class
    B shares, are those actually incurred for the fiscal year ended August 31,
    1995. Class B shares 'other expenses' are based on estimates for the Fund's
    current fiscal year.
 
(5) 12b-1 fees have two components, as follows:

annual return is not a prediction of, and does not represent, the projected or
actual performance of any Class of the Fund's shares.
 
THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES, AND THE FUND'S ACTUAL EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN.
The actual expenses attributable to each Class of the Fund's shares will depend
upon, among other things, the level of average net assets and the extent to
which the Fund incurs variable expenses, such as transfer agency costs.

DIFFERENCES AMONG THE CLASSES
 
     The primary distinctions among the Classes of the Fund's shares lie in
their initial and contingent deferred sales charge structures and in their
ongoing expenses, including asset-based sales charges in the form of
distribution fees. These differences are summarized in the table below. Each
Class has distinct advantages and disadvantages for different investors, and
investors may choose the Class that best suits their circumstances and
objectives.

                         first year after purchase
</TABLE>
 
FACTORS TO CONSIDER IN CHOOSING A CLASS OF SHARES
 
In deciding which Class of shares to purchase, investors should consider the
cost of sales charges together with the cost of the ongoing annual expenses
described below, as well as any other relevant facts and circumstances:
 
SALES CHARGES.  Class A shares are sold at net asset value plus an initial sales
charge of up to 4.5% of the public offering price. Because of this initial sales
charge, not all of a Class A shareholder's purchase price is invested in the
Fund. Class B shares are sold with no initial sales charge, but a contingent
deferred sales charge of up to 5% of the redemption proceeds applies to
redemptions made within six years of purchase. Class C shareholders pay no
initial sales charges, although a contingent deferred sales charge of 1.00%
applies to certain redemptions of Class C shares made within the first year
after purchase. Thus, the entire amount of a Class B or Class C shareholder's
purchase price is immediately invested in the Fund.
 
WAIVERS AND REDUCTIONS OF CLASS A SALES CHARGES.  Class A share purchases over
$50,000 and Class A share purchases made under the Fund's reduced sales charge
schedule may be made at a reduced sales charge. In considering the combined cost
of sales charges and ongoing annual expenses, investors should take into account
any reduced sales charges on Class A shares for which they may be eligible.
 
The entire initial sales charge on Class A shares is waived for certain eligible
purchasers. Because Class A shares bear lower ongoing annual expenses than Class
B shares or Class C shares, investors eligible for complete waivers should
purchase Class A shares.
 
ONGOING ANNUAL EXPENSES.  All three Classes of Fund shares pay an annual 12b-1
service fee of 0.25% of average daily net assets. Class B and Class C shares pay
an annual 12b-1 distribution

PAINEWEBBER TACTICAL ALLOCATION FUND





fee of 0.75% of average daily net assets. Annual 12b-1 distribution fees are a
form of asset-based sales charges. An investor should consider both ongoing
annual expenses and initial or contingent deferred sales charges in estimating
the costs of investing in the respective Classes of Fund shares over various
time periods.
 
For example, assuming a constant net asset value, the cumulative distribution
fees on the Class B or Class C shares and the 4.5% maximum initial sales charge
on the Class A shares would all be approximately equal if the shares were held
for six years. Because Class B shares convert to Class A shares (which do not
bear the expense of ongoing distribution fees) approximately six years after
purchase, an investor expecting to hold shares of the Fund for longer than six
years would generally pay lower cumulative expenses by purchasing Class A or
Class B shares than by purchasing Class C shares. An investor expecting to hold
shares of the Fund for less than six years would generally pay lower cumulative
expenses by purchasing Class C shares than by purchasing Class A shares, and,
due to the contingent deferred sales charges that would become payable on
redemption of Class B shares, such an investor would generally pay lower
cumulative expenses by purchasing Class C shares than Class B shares.
 
The foregoing examples do not reflect, among other variables, the cost or
benefit of bearing sales charges or distribution fees at the time of purchase,
upon redemption or over time, nor can they reflect fluctuations in the net asset
value of Fund shares, which will affect the actual amount of expenses paid.
Expenses borne by Classes may differ slightly because of the allocation of other
Class-specific expenses. The 'Example of Effect of Fund Expenses' under
'Prospectus Summary' shows the cumulative expenses an investor would pay over
time on a hypothetical investment in each Class of Fund shares, assuming an
annual return of 5%.
 
OTHER INFORMATION
 
PaineWebber investment executives may receive different levels of compensation
for selling one particular Class of Fund shares rather than another. Investors
should understand that distribution fees and initial and contingent deferred
sales charges all are intended to compensate Mitchell Hutchins for distribution
services.
 
See 'Purchases,' 'Redemptions' and 'Management' for a more complete description
of the initial and contingent deferred sales charges, service fees and
distribution fees for the three Classes of shares. See also 'Conversion of Class
B Shares,' 'Dividends, Distributions and Taxes,' 'Valuation of Shares' and
'General Information' for other differences among the three Classes.

                       INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
OBJECTIVE
 
The Fund's investment objective is long-term capital appreciation. The Fund
seeks to achieve its objective by investing primarily in equity securities of
small capitalization companies.
 
There can be no assurance that the Fund will achieve its investment objective.
The Fund's net asset value will fluctuate based upon changes in the value of its
portfolio securities. The Fund's investment objective and certain investment
limitations, as described in the Statement of Additional Information, are
fundamental policies and may not be changed without shareholder approval. All
other investment policies may be changed by the Trust's board of trustees
without shareholder approval.
 
ASSET ALLOCATION STRATEGY
 
The Fund is designed for investors seeking total return during all economic and
financial market cycles, with a degree of volatility lower than that of the
equity market, utilizing a systematic, cost-effective approach to allocating
assets among market segments. At the same time, the Fund provides individual
investors a means of dealing with the difficulties often associated with asset
allocation investing with an index component.
 
In seeking total return, the Fund follows an asset allocation strategy
contemplating shifts (some-

times frequent) among the following Segments: (i) the Stock Segment, consisting
primarily of the common stocks included in the S&P 500 Index and derivative
instruments relating thereto, the performance of which, before deduction of
operating expenses, is intended to replicate as closely as possible that of the
S&P 500 Index; (ii) the Cash Segment, consisting of 30-day U.S. Treasury Bills;
and (iii) the Note Segment, consisting of five-year U.S. Treasury Notes and
derivative instruments relating thereto.
 

The Fund allocates its assets among the Segments in accordance with the
Allocation Model. The emphasis of the Allocation Model is to avoid or lower
exposure to the market in down economic cycles and to perform close to the broad
market in periods of strongly positive market performance. The asset allocation
mix for the Fund will be determined by Mitchell Hutchins at any given time on
the basis of the recommendations of the Allocation Model, except as described
below, which are determined in light of a quantitative assessment of the
expected performance of the Segments. The Fund is not managed as a balanced
portfolio, however, and may not maintain a portion of its investments in each of
the Segments at all times. Except for limited amounts always held in the Cash
Segment as described below, the Fund does not commit its assets simultaneously
to the Cash Segment and the Note Segment. Thus, during the course of a business
cycle, for example, the Fund may invest in the Stock Segment and the Cash
Segment, in the Stock Segment and the Note Segment, solely in the Stock Segment,
solely in the Cash Segment or solely in the Note Segment.

 
The Fund's assets are reallocated among the Segments at such times as are
mandated by the Allocation Model based on changes in projected rates of return.
If no reallocation is mandated, on the first business day of each month, any
material amounts in each Segment in excess of the amount mandated by the
Allocation Model resulting from appreciation or receipt of dividends,
distributions, interest payments and proceeds from securities maturing are
reallocated (or 'rebalanced') to the extent practicable among the Segments so as
to reestablish the recommended allocation among the Segments.

Cash inflows to the Fund during a month are invested in, and cash outflows from
the Fund during a month are derived from dispositions of assets in, each Segment
on a pro rata basis. In order to manage the Fund's portfolio most effectively,
cash flows into and out of the Stock Segment are managed to the extent
practicable through the use of stock index options, stock index futures
contracts and options on stock index futures contracts, as described below.
Similarly, cash flows into and out of the Note Segment are managed to the extent
practicable through the use of five-year U.S. Treasury Note futures contracts
and options thereon. See 'Investment Strategies and Techniques -- Derivative
Instruments' below.
 
The Fund deviates from the published recommendations of the Allocation Model
only to the extent necessary (1) to maintain a limited amount of assets (not
expected to exceed 2% of its total assets) in the Cash Segment in order to have
highly liquid short-term securities available to pay Fund operating expenses and
dividends and distributions on its shares and to meet anticipated redemptions of
its shares and (2) to qualify as a regulated investment company for Federal
income tax purposes. With regard to the latter, investors should be aware that
in order to so qualify, the Fund must, among other things, derive less than 30%
of its gross income from the sale or disposition of stocks, other securities and
certain financial instruments held for less than three months. Thus, this
requirement may preclude the Fund from reallocating its assets when otherwise
mandated by the Allocation Model. In such event, the Fund would reallocate its
assets in accordance with the then current recommendations of the Allocation
Model as soon as the reallocation could be accomplished without jeopardizing the
Fund's qualification as a regulated investment company.
 
TYPES OF PORTFOLIO INVESTMENTS
 
CASH SEGMENT.  Assets committed to the Cash Segment are invested to the extent
practicable in U.S. Treasury Bills having remaining maturities of 30 days or, if
no such instruments are then available for purchase at favorable prices, these
assets will be invested in U.S. Treasury Bills having remaining maturities as
close as possible to 30 days. U.S. Treasury Bills are entitled to the full faith
and credit of the U.S. Government as to payment of interest and principal.
 
NOTE SEGMENT.  Assets committed to the Note Segment are invested to the extent
practicable in (1) U.S. Treasury Notes having five years remaining to maturity
at the beginning of the then current calendar year or, if no such instruments
are

then available for purchase at favorable prices, these assets will be invested
in U.S. Treasury Notes having remaining maturities as close as possible to five
years at the beginning of the then current calendar year; and (2) five-year U.S.
Treasury Note futures contracts and options thereon. U.S. Treasury Notes are
entitled to the full faith and credit of the U.S. Government as to payment of
interest and principal.
 
STOCK SEGMENT.  With respect to assets committed to the Stock Segment, the Fund
attempts to duplicate, before deduction of operating expenses, the investment
results of the S&P 500 Index. The S&P 500 Index is an index compiled by Standard
& Poor's Corporation ('S&P') that emphasizes large-capitalization companies. The
Stock Segment is not managed according to traditional methods of 'active'
investment management, which involve the buying and selling of securities based
on economic, financial and market analysis and investment judgment. Instead,
utilizing a 'passive' or 'indexing' investment approach, the Fund attempts in
the Stock Segment to duplicate the investment performance of the S&P 500 Index
through statistical procedures that involve holding substantially all 500 stocks
in approximately the same relative proportions as they are represented in the
S&P 500 Index, except as described below.
 
The S&P 500 Index is composed of 500 common stocks that are chosen by S&P on a
statistical basis. The composition of the S&P 500 Index is determined by S&P
based on such factors as the market capitalization and trading activity of each
stock and its adequacy as a representative of stocks in a particular industry
group, and may be changed from time to time. Each stock in the S&P 500 Index is
weighted by its market capitalization, which is the market price per share of
the stock multiplied by the number of shares outstanding. While most of the
stocks in the S&P 500 Index are issued by companies that are among the 500
largest companies in terms of market capitalization, some stocks are included
for diversification and are not among the 500 largest market capitalization
stocks. The inclusion of a stock in the S&P 500 Index in no way implies that S&P
believes the stock to be an attractive investment.

While there can be no guarantee that the Stock Segment's investment results will
precisely match those of the S&P 500 Index, Mitchell Hutchins believes that,
before deduction of operating expenses, there will be a very high correlation
between the returns generated by the Stock Segment and the S&P 500 Index. The
Fund attempts to achieve a correlation between the performance of the Stock
Segment and that of its benchmark index of at least 0.95, before deduction of
operating expenses. A correlation of 1.00 would indicate perfect correlation,
which would be achieved when the Stock Segment's net asset value, including the
value of its dividend and capital gains distributions, increases or decreases in
exact proportion to changes in the S&P 500 Index. The Fund's ability to
correlate the performance of the Stock Segment with the S&P 500 Index may be
affected by, among other things, changes in securities markets, the manner in
which the S&P 500 Index is calculated by S&P and the timing of purchases and
redemptions. See 'Risk Factors and Special Considerations -- Index Investing
and Open-End Investment Companies' below. Mitchell Hutchins monitors the
correlation of the performance of the Stock Segment in relation to that of the
S&P 500 Index under the supervision of the Board of Trustees. In the unlikely
event that a high correlation is not achieved, the Board of Trustees will take

INVESTMENT TECHNIQUES AND STRATEGIES
 
The Fund is authorized to engage in any one or more of the specialized
investment techniques and strategies described below:
 
DERIVATIVE INSTRUMENTS.  The Fund anticipates that the Note Segment and the
Stock Segment will remain invested in five-year U.S. Treasury Notes or common
stocks, respectively, to the degree mandated by the Allocation Model. The Fund
may also invest its assets in stock index options, stock index futures contracts
and options on stock index futures contracts (with respect to the Stock Segment)
and five-year U.S. Treasury Note futures contracts and options thereon (with
respect to the Note Segment) in order to invest temporarily uncommitted cash
balances, to maintain liquidity to meet shareholder redemptions or, in the case
of stock index options, to minimize trading costs. When the Fund has cash from
net new sales of Fund shares or holds a disproportionate amount of its assets in
the Cash Segment, it may enter into stock index futures or options thereon or
five-year U.S. Treasury Note futures contracts or options thereon to attempt

 PAINEWEBBER   TACTICAL ALLOCATION FUND

to increase its exposure to the appropriate asset class prior to purchasing
securities to the degree mandated by the Allocation Model. Strategies the Fund
could use to accomplish this include entering into long futures contracts,
writing put options and purchasing call options. When the Fund wishes to sell
securities, because of shareholder redemptions or otherwise, it may use futures
contracts or options to hedge against market risk until the sale can be
completed. These strategies could include entering into short futures contracts,
writing call options and purchasing put options. It is anticipated that the Fund
will continue to close out positions in these instruments on at least a
quarterly basis and reconstitute its portfolio with direct purchases or sales of
securities in accordance with the then current recommendations of the Allocation
Model. The Fund does not enter into futures contracts or options as part of a
temporary defensive strategy, such as lowering the Stock Segment's investment in
common stocks to protect against potential stock market declines, as this would
be inconsistent with the Allocation Model. See 'Stock Index Options' and
'Futures Contracts and Options on Futures Contracts' below.
 
STOCK INDEX OPTIONS.  The Fund may purchase and write put and call options on
stock indexes listed on domestic securities exchanges (which indexes include
securities held in the Fund's portfolio) as a means of pursuing the Stock
Segment's exposure in equity markets without making direct purchases of equity
securities.
 
A stock index measures the movement of a certain group of stocks by assigning
relative values to the common stocks included in the index. Options on stock
indexes are generally similar to options on specific securities. Unlike those on
securities, however, options on stock indexes do not involve the delivery of an
underlying security; the option in the case of an option on a stock index
represents the holder's right to obtain from the writer in cash a fixed multiple
of the amount by which the exercise price exceeds (in the case of a put) or is
less than (in the case of a call) the closing value of the underlying stock
index on the exercise date.
 
When the Fund writes an option on a stock index, it establishes a segregated
account with its custodian in which the Fund deposits cash or cash equivalents
or a combination of both in an amount equal to the market value of the option
and maintains the account while the option is open. If the Fund has written a
stock index option, it may terminate its obligation by effecting a closing
purchase transaction, which is accomplished by purchasing an option of the same
series as the option previously written.
 
FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.  The Fund may enter into
stock index futures contracts, and options on those contracts, as a means of
temporarily increasing or decreasing the Stock Segment's exposure to equity
markets in anticipation of purchases or sales of common stocks. Similarly, the
Fund may enter into five-year U.S. Treasury Note futures contracts, and options
on those contracts, as a means of temporarily increasing or decreasing the Note
Segment's exposure to five-year U.S. Treasury Notes in anticipation of purchase
or sales of these notes. A futures contract is an agreement to take or make
delivery of an amount of cash equal to the difference between the value of the
index or security at the beginning and at the end of the contract period. An
option on a futures contract, in contrast to a direct investment in the
contract, gives the purchaser the right, in return for the premium paid, to
assume a position in the underlying futures contract at a specified exercise
price at any time on or before the expiration date of the option.
 
The Fund may assume both 'long' and 'short' positions with respect to futures
contracts. A long position involves entering into a futures contract to buy a
commodity, whereas a short position involves entering into a futures contract to
sell a commodity. In entering into futures contracts, the Fund is required to
make initial 'margin' payments, which are payments in the nature of performance
bonds or good faith deposits, and to make 'variation' margin payments from time
to time as the values of the futures contracts fluctuate.
 
The Fund does not (1) enter into any futures contracts or options on futures
contracts if, immediately after the transactions, the aggregate of margin
deposits on all of the Fund's outstanding futures contracts and premiums paid on
its outstanding options on futures contracts would exceed 5% of the market value
of the total assets of the Fund after taking into account unrealized profits and
losses on any futures contracts or options on futures contracts or (2) enter
into any futures contracts or options on futures contracts if the aggregate of
the market value of the Fund's outstanding futures contracts and market value of
the currencies and futures contracts sub-

- --------------------------------------------------------------------------------
PAINEWEBBER   TACTICAL ALLOCATION FUND

ject to outstanding options written by the Fund would exceed 50% of the market
value of the total assets of the Fund. Each short position in a futures or
options contract entered into by the Fund is secured by the Fund's ownership of
underlying securities. The Fund does not use leverage when it enters into long
futures or options contracts; the Fund places in a segregated account with its
custodian, or designated sub-custodian, with respect to each of its long
positions cash or short-term U.S. Treasury Bills having a value equal to the
underlying commodity value of the contract.
 
REPURCHASE AGREEMENTS.  In order to manage cash flows resulting from the
continuous sale and redemption of the Fund's shares, the Fund may engage in
repurchase agreement transactions collateralized by U.S. Treasury obligations.
Although the amount of the Fund's assets that may be invested in repurchase
agreements terminable in less than seven days is not limited, repurchase
agreements maturing in more than seven days, together with other illiquid
securities, may not exceed 10% of the Fund's net assets. The Fund may engage in
repurchase agreement transactions with certain member banks of the Federal
Reserve System and with certain dealers listed on the Federal Reserve Bank of
New York's list of reporting dealers. Under the terms of a typical repurchase
agreement, the Fund would acquire an underlying debt obligation for a relatively
short period (usually not more than seven days) subject to an obligation of the
seller to repurchase, and the Fund to resell, the obligation at an agreed-upon
price and time, thereby determining the yield during the Fund's holding period.
This arrangement results in a fixed rate of return that is not subject to market
fluctuations during the Fund's holding period. The value of the securities
underlying a repurchase agreement of the Fund is monitored on an ongoing basis
by Mitchell Hutchins to ensure that the value is at least equal at all times to
the total amount of the repurchase obligation, including interest. Mitchell
Hutchins also monitors, on an ongoing basis to evaluate potential risks, the
creditworthiness of those banks and dealers with which the Fund enters into
repurchase agreements.
 
WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES.  To secure prices or yields deemed
advantageous at a particular time, the Fund may purchase securities on a
when-issued or delayed-delivery basis, in which case delivery of the securities
occurs beyond the normal settlement period; payment for or delivery of the
securities would be made prior to the reciprocal delivery or payment by the
other party to the transaction. The Fund enters into when-issued or
delayed-delivery transactions for the purpose of acquiring securities and not
for the purpose of leverage. When-issued securities purchased by the Fund may
include securities purchased on a 'when, as and if issued' basis under which the
issuance of the securities depends on the occurrence of a subsequent event, such
as approval of a merger, corporate reorganization or debt restructuring. The
Fund will establish with its custodian, or with a designated sub-custodian, a
segregated account consisting of cash, securities issued or guaranteed by the
U.S. Government, its agencies, authorities or instrumentalities ('Government
Securities') or other liquid high-grade debt obligations in an amount equal to
the amount of its when-issued or delayed-delivery purchase commitments.
 
RISK FACTORS AND SPECIAL CONSIDERATIONS
 
Investing in the Fund involves risks and special considerations, such as those
described below:
 
LIMITS OF ASSET ALLOCATION STRATEGY.  Although it seeks total return, consisting
of both capital appreciation and current income, in following its asset
allocation strategy, the Fund may not achieve as high a level of either capital
appreciation or current income as a fund that has only one of those objectives
as its primary objective. In addition, qualification as a regulated investment
company for federal income tax purposes may limit the Fund's ability to adhere
rigidly to the recommendations of the Allocation Model. See 'Asset Allocation
Strategy' above.
 
INVESTMENT IN COMMON STOCKS.  Although the Allocation Model is designed to
reduce the volatility inherent in a common stock portfolio, to the extent the
Fund's assets are committed to the Stock Segement, the share price of the Fund
can be expected to be volatile and investors should be able to tolerate sudden,
sometimes substantial fluctuations in the value of their investment. Because of
the risks associated with common stock investments, the Fund is intended to be a
long term investment vehicle and is not designed to provide investors with a
means of speculating on short-term stock market movements.

 PAINEWEBBER   TACTICAL ALLOCATION FUND


INDEX INVESTING AND OPEN-END INVESTMENT COMPANIES.  While the Fund through the
Stock Segment attempts to replicate, before deduction of operating expenses, the
investment results of the S&P 500 Index, the investment results of the Stock
Segment generally are not identical to those of the designated index. Deviations
from the performance of the S&P 500 Index may result from shareholder purchases
and redemptions of shares of the Fund that occur daily, as well as from the
expenses borne by the Fund. Shareholder purchases and redemptions result in
daily net cash inflows to or outflows from the Fund. To the extent that a cash
reserve is held to meet expected redemptions or pending investment in portfolio
securities, to the extent that portfolio securities must be sold to meet
redemption requests (with resulting brokerage costs), and to the extent that
purchases and sales of portfolio securities are made to conform the Stock
Segment's holdings more closely to the relative weightings of stocks in the S&P
500 Index in response to cash inflows or outflows and associated brokerage costs
are incurred, these daily inflows or outflows of cash may increase the deviation
between the Stock Segment's investment results and the price and yield
performance of the S&P 500 Index.
 
INVESTMENT IN FOREIGN SECURITIES.  Since the S&P 500 Index includes common
stocks of foreign issuers, to the extent that Fund assets are committed to the
Stock Segment, the Fund is subject to considerations and potential risks not
typically associated with investing in securities issued exclusively by domestic
corporations. The values of foreign investments are affected by changes in
currency exchange rates or exchange control regulations, restrictions or
prohibitions on the repatriation of foreign currencies, application of foreign
tax laws, including withholding taxes, changes in governmental administration or
economic or monetary policy (in the United States or abroad) or changed
circumstances in dealings between nations. Investments in foreign companies
could be affected by other factors not present in the United States, including
expropriation, confiscatory taxation, lack of uniform accounting and auditing
standards and potential difficulties in enforcing contractual obligations.

STOCK INDEX OPTIONS.  Stock index options are subject to position and exercise
limits and other regulations imposed by the exchange on which they are traded.
If the Fund writes a stock index option, it may terminate its obligation by
effecting a closing purchase transaction, which is accomplished by purchasing an
option of the same series as the option previously written. The ability of the
Fund to engage in closing purchase transactions with respect to stock index
options depends on the existence of a liquid secondary market. Although the Fund
generally purchases or writes stock index options only if a liquid secondary
market for the options purchased or sold appears to exist, no such secondary
market may exist, or the market may cease to exist at some future date, for some
options. No assurance can be given that a closing purchase transaction can be
effected when the Fund desires to engage in such a transaction.
 
FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. In entering into
transactions involving futures contracts and options on those contracts, the
Fund is subject to a number of risks and special considerations. The successful
use of futures contracts and options on those contracts draws upon Mitchell
Hutchins' special skills and experience with respect to those instruments.
Should markets move in an unexpected manner, the Fund may not achieve the
anticipated benefits of futures contracts or options on those contracts and thus
be in a less advantageous position than if those strategies had not been used.
For a number of reasons, the price of futures may not correlate perfectly with
the movement in the underlying index or security owing to certain market
distortions. First, all participants in the futures market are subject to margin
deposit and maintenance requirements. Rather than meeting additional margin
deposit requirements, investors may close futures contracts through offsetting
transactions that would distort the normal relationship between the underlying
index or security and the futures markets. Second, from the point of view of
speculators, the deposit requirements in the futures market are less onerous
than margin requirements in the securities market. Therefore, increased
participation by speculators in the futures market also may cause temporary
price distortions. Owing to the possibility of price distortions in the futures
market and because of the imperfect correlation between movements in the
underlying index or security and movements in the price of futures contracts,
even a correct forecast of general market trends may not result in a successful
hedging transaction.
 
Certain futures contracts and options on futures contracts are subject to no
daily price fluctuation limits so that adverse market movements could

PAINEWEBBER   TACTICAL ALLOCATION FUND


continue with respect to those instruments to an unlimited extent over a period
of time.
 
The Fund's ability to dispose of its positions in futures contracts and options
on those contracts depends on the availability of active markets in those
instruments. Markets in options and futures with respect to a number of
securities are relatively new and still developing. Mitchell Hutchins cannot now
predict the amount of trading interest that may exist in the future in various
types of futures contracts and options. Futures and options may be closed out
only on the exchange on which the contract was entered (or a linked exchange) so
that no assurance can be given that the Fund will be able to utilize these
instruments effectively for the purposes described above. In addition, although
the Fund anticipates that its options and futures transactions does not prevent
the Fund from qualifying as a regulated investment company for federal income
tax purposes, the Fund's ability to engage in options and futures transactions
may be limited by this tax consideration. See 'Dividends, Distributions and
Taxes -- Taxes.' In writing options, the Fund is subject to the risk of loss
resulting from the difference between the premium received for the option and
the price of the futures contract underlying the option that the Fund must
purchase or deliver upon exercise of the option.
 
REPURCHASE AGREEMENTS.  In entering into a repurchase agreement, the Fund bears
a risk of loss in the event that the other party to the transaction defaults on
its obligations and the Fund is delayed or prevented from exercising its rights
to dispose of the underlying securities, including the risk of a possible
decline in the value of the underlying securities during the period in which the
Fund seeks to assert its rights to them, the risk of incurring expenses
associated with asserting those rights and the risk of losing all or a part of
the income from the agreement.
 
WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES. Securities purchased on a
when-issued or delayed-delivery basis may expose the Fund to risk because the
securities may experience fluctuations in value prior to their actual delivery.
The Fund does not accrue income with respect to a when-issued or
delayed-delivery security prior to its stated delivery date. Purchasing
securities on a when-issued or delayed-delivery basis can involve the additional
risk that the yield available in the market when the delivery takes place may be
higher than that obtained in the transaction itself. Purchases of securities on
a when-issued basis when the Fund is substantially fully invested may result in
increased fluctuations in the Fund's net asset value per share.
 
PORTFOLIO TRANSACTIONS AND TURNOVER
 
The Board of Trustees of the Trust has determined that, to the extent consistent
with applicable provisions of the 1940 Act and rules and exemptions thereunder,
transactions for the Fund may be executed through PaineWebber if, in the
judgment of Mitchell Hutchins, the use of PaineWebber is likely to result in
price and execution at least as favorable to the Fund as those obtainable
through other qualified broker-dealers, and if, in the transaction, PaineWebber
charges the Fund a fair and reasonable rate consistent with that charged to
comparable unaffiliated customers in similar transactions.
 
The Fund retains the right to sell securities in accordance with recommendations
generated by the Allocation Model irrespective of how long they have been held.
For the fiscal years ended August 31, 1995 and August 31, 1994, the Fund's
portfolio turnover rates were 53.02% and 4.17%, respectively. An annual turnover
rate of 100% would occur if all of the securities held by the Fund are replaced
once during a period of one year. Higher portfolio turnover rates can result in
corresponding increases in transaction costs, may make it more difficult for the
Fund to qualify as a regulated investment company for federal income tax
purposes and may cause shareholders of the Fund to recognize gains for federal
income tax purposes. See 'Dividends, Distributions and Taxes -- Taxes.'
 
Assuming that the Allocation Model does not recommend a reallocation of assets
among the Segments, securities are sold from the Stock Segment only to reflect
certain administrative changes in the S&P 500 Index (including mergers or
changes in the composition of the S&P 500 Index) or to accommodate cash flows
into and out of the Fund while maintaining the similarity of the Stock Segment
to its benchmark. Similarly, assets are purchased or sold for each Segment
monthly, as described above, in order to accommodate cash flows and to rebalance
assets among the Segments.

GENERAL.  Class A shares are sold to investors subject to an initial sales
charge. Class B shares are sold without an initial sales charge but are subject
to higher ongoing expenses than Class A shares and a contingent deferred sales
charge payable upon certain redemptions. Class B shares automatically convert to
Class A shares approximately six years after issuance. Class C shares are sold
without an initial sales charge but are subject to a 1% contingent deferred
sales charge for redemptions made within one year and to higher ongoing expenses
than Class A shares and do not convert into another Class. See 'Flexible Pricing
System' and 'Conversion of Class B Shares.'
 
Shares of the Fund are available through PaineWebber and its correspondent firms
or, for shareholders who are not PaineWebber clients, through the Transfer
Agent. Investors may contact a local PaineWebber office to open an account. The
minimum initial investment is $1,000, and the minimum for additional purchases
is $100. These minimums may be waived or reduced for investments by employees of
PaineWebber or its affiliates, certain pension plans and retirement accounts and
participants in the Fund's automatic investment plan. Purchase orders will be
priced at the net asset value per share next determined (see 'Valuation of
Shares') after the order is received by PaineWebber's New York City offices or
by the Transfer Agent, plus any applicable sales charge for Class A shares. The
Fund and Mitchell Hutchins reserve the right to reject any purchase order and to
suspend the offering of Fund shares for a period of time.
 
When placing purchase orders, investors should specify whether the order is for
Class A, Class B or Class C shares. All share purchase orders that fail to
specify a Class will automatically be invested in Class A shares.

PURCHASES THROUGH PAINEWEBBER OR CORRESPONDENT FIRMS.  Purchases through
PaineWebber investment executives or correspondent firms may be made in person
or by mail, telephone or wire; the minimum wire purchase is $1 million.
Investment executives and correspondent firms are responsible for transmitting
purchase orders to PaineWebber's New York City offices promptly. Investors may
pay for purchases with checks drawn on U.S. banks or with funds held in
brokerage accounts at PaineWebber or its correspondent firms. Payment is due on
the third Business Day after the order is received at PaineWebber's New York
City offices. A 'Business Day' is any day, Monday through Friday, on which the
New York Stock Exchange, Inc. ('NYSE') is open for business.
 
PURCHASES THROUGH THE TRANSFER AGENT.  Investors who are not PaineWebber clients
may purchase shares of the Fund through the Transfer Agent. Shares of the Fund
may be purchased, and an account with the Fund established, by completing and
signing the purchase application at the end of this Prospectus and mailing it,
together with a check to cover the purchase, to the Transfer Agent: PFPC Inc.,
Attn: PaineWebber Mutual Funds, P.O. Box 8950, Wilmington, Delaware 19899.
Subsequent investments need not be accompanied by an application.
 
INITIAL SALES CHARGE -- CLASS A SHARES.   The public offering price of Class A
shares is the next determined net asset value, plus any applicable sales charge,
which will vary with the size of the purchase as shown in the table below.
 
Mitchell Hutchins may at times agree to reallow higher discounts to PaineWebber,
as exclusive dealer for the Fund's shares, than those shown in the table below.
To the extent PaineWebber or any dealer receives 90% or more of the sales
charge, it may be deemed an 'underwriter' under the 1933 Act.

PAINEWEBBER   TACTICAL ALLOCATION FUND


SALES CHARGE WAIVERS -- CLASS A SHARES.  Class A shares of the Fund are
available without a sales charge through exchanges for Class A shares of most
other PaineWebber mutual funds. See 'Exchanges.' In addition, Class A shares may
be purchased without a sales charge by employees, directors and officers of
PaineWebber or its affiliates, directors or trustees and officers of any
PaineWebber mutual fund, their spouses, parents and children and advisory
clients of Mitchell Hutchins. Class A shares may also be purchased without a
sales charge by employee benefit plans qualified under section 401 or 403(b) of
the Internal Revenue Code (the 'Code'), including salary reduction plans
qualified under section 401(k) of the Code, subject to minimum requirements
established by Mitchell Hutchins with respect to number of employees or amount
of purchase. Currently, the employers establishing the plan must have 100 or
more eligible employees or the amount invested or to be invested during the
subsequent 13-month period in the Fund or any other PaineWebber mutual fund must
total at least $1 million. If investments by an employee benefit plan without a
sales charge are made through a dealer (including PaineWebber) who has executed
a dealer agreement with Mitchell Hutchins, Mitchell Hutchins may make a payment,
out of its own resources, to the dealer in an amount not to exceed 1% of the
amount invested.

 
Class A shares also may be purchased without a sales charge if the purchase is
made through a PaineWebber investment executive who formerly was employed as a
broker with another firm registered as a broker-dealer with the SEC, provided
(1) the purchaser was the investment executive's client at the competing
brokerage firm, (2) within 90 days of the purchase of Class A shares the
purchaser redeemed shares of one or more mutual funds for which that competing
firm or its affiliates was principal underwriter, provided the purchaser either
paid a sales charge to invest in those funds, paid a contingent deferred sales
charge upon redemption or held shares of those funds for the period required not
to pay the otherwise applicable contingent deferred sales charge and (3) the
total amount of shares of all PaineWebber mutual funds purchased under this
sales charge waiver does not exceed the amount of the purchaser's redemption
proceeds from the competing firm's funds. To take advantage of this waiver, an
investor must provide satisfactory evidence that all the above-noted conditions
are met. Qualifying investors should contact their PaineWebber investment
executives for more information.
 
Certificate holders of unit investment trusts ('UITs') sponsored by PaineWebber
may acquire Class A shares of the Fund without regard to minimum investment
requirements and without sales charges by electing to have dividends and other
distributions from their UIT investment automatically invested in Class A
shares.
 
CONTINGENT DEFERRED SALES CHARGE -- CLASS A SHARES.  Purchases of Class A shares
of $1 million or more may be made without a sales charge. Purchases of Class A
shares of two or more PaineWebber mutual funds may be combined for the purpose,
and the right of accumulation also applies to such purchases. See 'Reduced Sales
Charge Plans -- Class A Shares' below. If a shareholder redeems any Class A
shares that were purchased without a sales charge by reason of a purchase of $1
million or more within one year after the date of purchase, a contingent
deferred sales charge will be applied to the redemption. The Class A contingent
deferred sales charge will be equal to 1% of the lower of (a) the net asset
value of the shares at the time of purchase or (b) the net asset value of the
shares at the time of redemption. Class A shares of the Fund held one year or
longer, and Class A shares of the Fund acquired through reinvestment of
dividends or capital gains distributions will not be subject to this contingent
deferred sales charge. The contingent deferred sales charge for Class A shares
of the Fund will be waived for redemptions in connection with the systematic
withdrawal plan, subject to the limitations described below under 'Other
Services and Information -- Systematic Withdrawal Plan.' This contingent
deferred sales charge does not apply to redemptions of Class A shares purchased
prior to November 10, 1995.
 
Class A shares of the Fund that are purchased without a sales charge may be
exchanged for Class A shares of another PaineWebber mutual fund without the
imposition of a contingent deferred sales charge, although contingent deferred
sales charges may apply to the Class A shares acquired through an exchange. For
federal income tax purposes, the amount of the contingent deferred sales charge
will reduce the gain or increase the loss, as the case may be, on the amount
realized on the redemption. The

amount of any contingent deferred sales charge will be paid to Mitchell
Hutchins.
 
REDUCED SALES CHARGE PLANS -- CLASS A SHARES.  If an investor or eligible group
of related Fund investors purchases Class A shares of the Fund concurrently with
Class A shares of other PaineWebber mutual funds, the purchases may be combined
to take advantage of the reduced sales charge applicable to larger purchases. In
addition, the right of accumulation permits a Fund investor or eligible group of
related Fund investors to pay the lower sales charge applicable to larger
purchases by basing the sales charge on the dollar amount of Class A shares
currently being purchased, plus the net asset value of the investor's or group's
total existing Class A shareholdings in other PaineWebber mutual funds.
 
An 'eligible group of related Fund investors' includes an individual, the
individual's spouse, parents and children, the individual's individual
retirement account ('IRA'), certain companies controlled by the individual and
employee benefit plans of those companies, and trusts or Uniform Gifts to Minors
Act/Uniform Transfers to Minors Act accounts created by the individual or
eligible group of individuals for the benefit of the individual and/or the
individual's spouse, parents or children. The term also includes a group of
related employers and one or more qualified retirement plans of such employers.
For more information, an investor should consult the Statement of Additional
Information or contact a PaineWebber investment executive or correspondent firm
or the Transfer Agent.
 
CONTINGENT DEFERRED SALES CHARGE -- CLASS B SHARES.  The public offering price
of the Class B shares of the Fund is the next determined net asset value, and no
initial sales charge is imposed. A contingent deferred sales charge, however, is
imposed upon certain redemptions of Class B shares.
 
Class B shares that are redeemed will not be subject to a contingent deferred
sales charge to the extent that the value of such shares represents (1)
reinvestment of dividends or capital gain distributions or (2) shares redeemed
more than six years after their purchase. Otherwise, redemptions of Class B
shares will be subject to a contingent deferred sales charge. The amount of any
applicable contingent deferred sales charge will be calculated by multiplying
the lower of (a) the net asset value of the shares at the time of purchase or
(b) the net asset value of the shares at the time of redemption by the
applicable percentage shown in the table below:

6th Year Since Purchase.............            1
7th Year Since Purchase.............           None
</TABLE>
 
In determining the applicability and rate of any contingent deferred sales
charge, it will be assumed that a redemption is made first of Class B shares
representing capital appreciation, next of shares representing the reinvestment
of dividends and capital gain distributions and finally of other shares held by
the shareholder for the longest period of time. The holding period of Class B
shares acquired through an exchange with another PaineWebber mutual fund will be
calculated from the date that the Class B shares were initially acquired in one
of the other PaineWebber funds, and Class B shares being redeemed will be
considered to represent, as applicable, capital appreciation or dividend and
capital gain distribution reinvestments in such other funds. This will result in
any contingent deferred sales charge being imposed at the lowest possible rate.
For federal income tax purposes, the amount of the contingent deferred sales
charge will reduce the gain or increase the loss, as the case may be, realized
on the redemption. The amount of any contingent deferred sales charge will be
paid to Mitchell Hutchins.
 
SALES CHARGE WAIVERS -- CLASS B SHARES.  The contingent deferred sales charge
will be waived for exchanges, as described below, and for redemptions in
connection with the Fund's systematic withdrawal plan; In addition, the
contingent deferred sales charge will be waived for a total or partial
redemption made within one year of the death of the shareholder. The contingent
deferred sales charge waiver is available where the decedent is either the sole
shareholder or owns the shares with his or her spouse as a joint tenant with
right of survivorship. This waiver applies only to redemption of shares held at
the time of death. The contingent deferred sales charge will also be waived in
connection with a lump-sum or other distribution in the case of an IRA, a
self-employed individual retirement plan (so-called 'Keogh Plan') or a custodial
account

PAINEWEBBER   TACTICAL ALLOCATION FUND


under Section 403(b) of the Internal Revenue Code following attainment of age
59 1/2; any total or partial redemption resulting from a distribution following
retirement in the case of a tax-qualified retirement plan; and a redemption
resulting from a tax-free return of an excess contribution to an IRA.
 
Contingent deferred sales charge waivers will be granted subject to confirmation
(by PaineWebber in the case of shareholders who are PaineWebber clients or by
the Transfer Agent in the case of all other shareholders) of the shareholder's
status or holdings, as the case may be.
 
PURCHASES OF CLASS C SHARES.  The public offering price of the Class C shares is
the next determined net asset value. No initial or contingent deferred sales
charge is imposed.
 
CONTINGENT DEFERRED SALES CHARGE -- CLASS C SHARES.  If a shareholder redeems
Class C shares within a year after the date of the purchase, a contingent
deferred sales charge will be applied to the redemption. The contingent deferred
sales charge on Class C shares will be equal to 1.00% of the lower of: (a) the
net asset value of the shares at the time of purchase or (b) the net asset value
of the shares at the time of redemption. Class C shares of the Fund held one
year or longer and Class C shares of the Fund acquired through reinvestment of
dividends or capital gains distributions will not be subject to the contingent
deferred sales charge. The contingent deferred sales charge for Class C shares
of the Fund will be waived for redemptions in connection with the systematic
withdrawal plan, subject to the limitations described below under 'Other
Services and Information -- Systematic Withdrawal Plan.' This contingent
deferred sales charge does not apply to redemptions of Class C shares purchased
prior to November 10, 1995.
 
Class C shares of the Fund that are purchased without a sales charge may be
exchanged for Class C shares of another PaineWebber mutual fund without the
imposition of a contingent deferred sales charge, although contingent deferred
sales charges may apply to the Class C shares acquired through an exchange. For
federal income tax purposes, the amount of the contingent deferred sales charge
will reduce the gain or increase the loss, as the case may be, on the amount
realized on the redemption. The amount of any contingent deferred sales charge
will be paid to Mitchell Hutchins.

                                   EXCHANGES
- --------------------------------------------------------------------------------
 
Shares of the Fund may be exchanged for shares of the corresponding Class of the
PaineWebber mutual funds listed below, or may be acquired through an exchange of
shares of the corresponding Class of those funds. No initial sales charge is
imposed on the shares being acquired, and no contingent deferred sales charge is
imposed on the shares being disposed of, through an exchange. However,
contingent deferred sales charges may apply to redemptions of Class B shares of
PaineWebber mutual funds acquired through an exchange. Exchanges may be subject
to minimum investment requirements of the fund into which exchanges are made.
 
Exchanges are permitted between the Fund and other PaineWebber mutual funds,

PaineWebber clients must place exchange orders through their PaineWebber
investment executives or correspondent firms unless the shares to be exchanged
are held in certificated form. Shareholders who are not PaineWebber clients or
who hold their shares in certificated form must place exchange orders in writing
with the Transfer Agent: PFPC Inc., Attn: PaineWebber Mutual Funds, P.O. Box
8950, Wilmington, Delaware 19899. All exchanges will be effected based on the
relative net asset values per share next determined after the exchange order is
received at PaineWebber's New York City offices or by the Transfer Agent. See
'Valuation of Shares.' Shares of the Fund purchased through PaineWebber or its
correspondent firms may be exchanged only after the settlement date has passed
and payment for such shares has been made.
 
OTHER EXCHANGE INFORMATION.  This exchange privilege may be modified or
terminated at any time, upon at least 60 days' notice when such notice is
required by SEC rules. See the Statement of Additional Information for further
details. This exchange privilege is available only in those jurisdictions where
the sale of the PaineWebber mutual fund shares to be acquired may be legally
made. Before making any exchange, shareholders should contact their PaineWebber
investment executives or correspondent firms or the Transfer Agent to obtain
more information and prospectuses of the PaineWebber mutual funds to be acquired
through the exchange.
 
- --------------------------------------------------------------------------------
                                  REDEMPTIONS
- --------------------------------------------------------------------------------
 
As described below, Fund shares may be redeemed at their net asset value
(subject to any applicable contingent deferred sales charge) and redemption
proceeds will be paid after receipt of a redemption request as described below.
PaineWebber clients may redeem non-certificated shares through PaineWebber or
its correspondent firms; all other shareholders must redeem through the Transfer
Agent. If a redeeming shareholder owns shares of more than one Class, the shares
will be redeemed in the following order unless the shareholder specifically
requests otherwise: Class C shares, then Class A shares, and finally Class B
shares.
 
REDEMPTION THROUGH PAINEWEBBER OR CORRESPONDENT FIRMS.  PaineWebber clients may
submit redemption requests to their investment executives or correspondent firms
in person or by telephone, mail or wire. As the Fund's agent, PaineWebber may
honor a redemption request by repurchasing Fund shares from a redeeming
shareholder at the shares' net asset value next determined after receipt of the
request by PaineWebber's New York City offices. Within three Business Days after
receipt of the request, repurchase proceeds (less any applicable contingent
deferred sales charge) will be paid by check or credited to the shareholder's
brokerage account at the election of the shareholder. PaineWebber investment
executives and correspondent firms are responsible for promptly forwarding
redemption requests to PaineWebber's New York City offices.
 
PaineWebber reserves the right not to honor any redemption request, in which
case PaineWebber promptly will forward the request to the Transfer Agent for
treatment as described below.
 
REDEMPTION THROUGH THE TRANSFER AGENT.  Fund shareholders who are not
PaineWebber clients or who wish to redeem certificated shares must

PAINEWEBBER   TACTICAL ALLOCATION FUND


redeem their shares through the Transfer Agent by mail; other shareholders also
may redeem Fund shares through the Transfer Agent. Shareholders should mail
redemption requests directly to the Transfer Agent: PFPC Inc., Attn: PaineWebber
Mutual Funds, P.O. Box 8950, Wilmington, Delaware 19899. A redemption request
will be executed at the net asset value next computed after it is received in
'good order' and redemption proceeds will be paid within seven days of the
receipt of the request. 'Good order' means that the request must be accompanied
by the following: (1) a letter of instruction or a stock assignment specifying
the number of shares or amount of investment to be redeemed (or that all shares
credited to a Fund account be redeemed), signed by all registered owners of the
shares in the exact names in which they are registered, (2) a guarantee of the
signature of each registered owner by an eligible institution acceptable to the
Transfer Agent and in accordance with SEC rules, such as a commercial bank,
trust company or member of a recognized stock exchange, (3) other supporting
legal documents for estates, trusts, guardianships, custodianships, partnerships
and corporations and (4) duly endorsed share certificates, if any. Shareholders
are responsible for ensuring that a request for redemption is received in 'good
order.'
 
ADDITIONAL INFORMATION ON REDEMPTIONS.  A shareholder who holds non-certificated
Fund shares may have redemption proceeds of $1 million or more wired to the
shareholder's PaineWebber brokerage account or a commercial bank account
designated by the shareholder. Questions about this option, or redemption
requirements generally, should be referred to the shareholder's PaineWebber
investment executive or correspondent firm, or to the Transfer Agent if the
shares are not held in a PaineWebber brokerage account. If a shareholder
requests redemption of shares which were purchased recently, the Fund may delay
payment until it is assured that good payment has been received. In the case of
purchases by check, this can take up to 15 days.
 
Because the Fund incurs certain fixed costs in maintaining shareholder accounts,
the Fund reserves the right to redeem all Fund shares in any shareholder account
of less than $500 net asset value. If the Fund elects to do so, it will notify
the shareholder and provide the shareholder the opportunity to increase the
amount invested to $500 or more within 60 days of the notice. The Fund will not
redeem accounts that fall below $500 solely as a result of a reduction in net
asset value per share.
 
Shareholders who have redeemed Class A shares may reinstate their Fund account
without a sales charge up to the dollar amount redeemed by purchasing Class A
Fund shares within 365 days of the redemption. To take advantage of this
reinstatement privilege, shareholders must notify their PaineWebber investment
executive or correspondent firm at the time the privilege is exercised.
 
- --------------------------------------------------------------------------------
                          CONVERSION OF CLASS B SHARES
- --------------------------------------------------------------------------------
 
A shareholder's Class B shares will automatically convert to Class A shares
approximately six years after the date of issuance, together with a pro rata
portion of all Class B shares representing dividends and other distributions
paid in additional Class B shares. The Class B shares so converted will no
longer be subject to the higher expenses borne by Class B shares. The conversion
will be effected at the relative net asset values per share of the two Classes
on the first Business Day of the month in which the sixth anniversary of the
issuance of the Class B shares occurs. See 'Valuation of Shares.' If a
shareholder effects one or more exchanges among Class B shares of the
PaineWebber mutual funds during the six-year period, the holding periods for the
shares so exchanged will be counted toward the six-year period.

                         OTHER SERVICES AND INFORMATION
- --------------------------------------------------------------------------------
 
Investors interested in the services described below should consult their
PaineWebber investment executives or correspondent firms or call the Transfer
Agent toll-free at 1-800-647-1568.
 
AUTOMATIC INVESTMENT PLAN.  Shareholders may purchase shares of the Fund through
an automatic investment plan, under which an amount specified by the shareholder
of $50 or more each month will be sent to the Transfer Agent from the
shareholder's bank for investment in the Fund. In addition to providing a
convenient and disciplined manner of investing, participation in the automatic
investment plan enables the investor to use the technique of 'dollar cost
averaging.' When under the plan a shareholder invests the same dollar amount
each month, the shareholder will purchase more shares when the Fund's net asset
value per share is low and fewer shares when the net asset value per share is
high. Using this technique, a shareholder's average purchase price per share
over any given period will be lower than if the shareholder purchased a fixed
number of shares on a monthly basis during the period. Of course, investing
through the automatic investment plan does not assure a profit or protect
against loss in declining markets. Additionally, since the automatic investment
plan involves continuous investing regardless of price levels, an investor
should consider his or her financial ability to continue purchases through
periods of low price levels.
 
SYSTEMATIC WITHDRAWAL PLAN.  Shareholders who own Class A or Class C shares with
a value of $5,000 or more or non-certificated Class B shares with a value of
$20,000 or more may have PaineWebber redeem a portion of their shares monthly,
quarterly or semi-annually under the systematic withdrawal plan. No contingent
deferred sales charge will be imposed on such withdrawals for Class B shares.
The minimum amount for all withdrawals of Class A or Class C shares is $100, and
minimum monthly, quarterly and semi-annual withdrawal amounts for Class B shares
are $200, $400 and $600, respectively. Quarterly withdrawals are made in March,
June, September and December, and semi-annual withdrawals are made in June and
December. A Class B shareholder may not withdraw an amount exceeding 12%
annually of his or her 'Initial Account Balance,' a term that means the value of
the Fund account at the time the shareholder elects to participate in the
systematic withdrawal plan. A shareholder's participation in the systematic
withdrawal plan will terminate automatically if the Initial Account Balance
(plus the net asset value on the date of purchase of Fund shares acquired after
the election to participate in the systematic withdrawal plan), less aggregate
redemptions made other than pursuant to the systematic withdrawal plan, is less
than $20,000 in the case of Class B shares and $5,000 in the case of Class A or
Class C shares. No contingent deferred sales charge will be imposed on such
withdrawals within the first year after purchase for Class A shares purchased
pursuant to the sales charge waiver for purchases of $1 million or more or Class
C shares, provided that the Class A or Class C shareholder does not withdraw an
amount exceeding 12% in the first year after purchase of his or her Initial
Account Balance. Shareholders who receive dividends or other distributions in
cash may not participate in the systematic withdrawal plan. Purchases of
additional Fund shares concurrently with withdrawals are ordinarily
disadvantageous to shareholders because of tax liabilities and, for Class A
shares, sales charges.
 
INDIVIDUAL RETIREMENT ACCOUNTS.  Shares of the Fund may be purchased through
IRAs available through the Fund. In addition, a Self-Directed IRA is available
through PaineWebber under which investments may be made in the Fund as well as
in other investments available through PaineWebber. Investors considering
establishing an IRA should review applicable tax laws and should consult their
tax advisers.
 
TRANSFER OF ACCOUNTS.  If a shareholder holding shares of the Fund in a
PaineWebber brokerage account transfers his brokerage account to another firm,
the Fund shares normally will be transferred to an account with the Transfer
Agent. However, if the other firm has entered into a selected dealer agreement
with Mitchell Hutchins relating to the Fund, the shareholder may be able to hold
Fund shares in an account with the other firm.

PAINEWEBBER   TACTICAL ALLOCATION FUND


- --------------------------------------------------------------------------------
                       DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
DIVIDENDS AND DISTRIBUTIONS.  Dividends from net investment income and
distributions of net realized capital gains of the Fund, if any, are distributed
annually. Unless a shareholder instructs the Fund that dividends and capital
gains distributions on shares of any Class should be paid in cash and credited
to the shareholder's Account, dividends and capital gains distributions are
reinvested automatically at net asset value in additional shares of the same
Class. The Fund is subject to a 4% nondeductible excise tax measured with
respect to certain undistributed amounts of net investment income and capital
gains. If necessary to avoid the imposition of this tax, and if in the best
interests of its shareholders, the Fund will declare and pay dividends of its
net investment income and distributions of its net capital gains more frequently
than stated above. The per share dividends and distributions on Class A shares
are higher than those on Class B and Class C shares, as a result of the
distribution fees borne by Class B and Class C shares. Dividends on each Class
also might be affected differently by the allocation of other Class-specific
expenses. See 'Fee Table,' 'Purchase of Shares,' 'Distributor' and 'General
Information.'
 
TAXES.  The Fund has qualified for the fiscal year ended August 31, 1995 to be
treated as a regulated investment company within the meaning of the Code and
intends to qualify for this treatment for each year. To qualify as a regulated
investment company for federal income tax purposes, the Fund limits its income
and investments so that (1) less than 30% of its gross income is derived from
the sale or disposition of stocks, other securities and certain financial
instruments (including certain forward contracts) that were held for less than
three months and (2) at the close of each quarter of the taxable year (a) not
more than 25% of the market value of the Fund's total assets is invested in the
securities (other than Government Securities) of a single issuer or of two or
more issuers controlled by the Fund that are engaged in the same or similar
trades or businesses or in related trades or businesses and (b) at least 50% of
the market value of the Fund's total assets is represented by (i) cash and cash
items, (ii) Government Securities and (iii) other securities limited in respect
of any one issuer to an amount not greater in value than 5% of the market value
of the Fund's total assets and to not more than 10% of the outstanding voting
securities of the issuer. The requirements for qualification may cause the Fund
to restrict the degree to which it sells or otherwise disposes of stocks, other
securities and certain financial instruments held for less than three months. If
the Fund qualifies as a regulated investment company and meets certain
distribution requirements, the Fund will not be subject to federal income tax on
its net investment income and net realized capital gains that it distributes to
its shareholders.
 
Dividends paid by the Fund out of net investment income and distributions of net
realized short-term capital gains are taxable to shareholders as ordinary
income, whether received in cash or reinvested in additional Fund shares.
Distributions of net realized long-term capital gains are taxable to
shareholders as long-term capital gain, regardless of how long shareholders have
held their shares and whether the distributions are received in cash or
reinvested in additional shares. Dividends and distributions paid by the Fund
generally do not qualify for the federal dividends received deduction for
corporate shareholders.
 
Statements as to the tax status of each Fund shareholder's dividends and
distributions are mailed annually. Shareholders also receive, as appropriate,
various written notices after the close of the Fund's taxable year regarding the
tax status of certain dividends and distributions that were paid (or that are
treated as having been paid) by the Fund to its shareholders during the
preceding taxable year, including the amount of dividends that represent
interest derived from Government Securities.
 
Shareholders are urged to consult their tax advisors regarding the application
of federal, state, local and foreign tax laws to their specific situations
before investing in the Fund.

PAINEWEBBER   TACTICAL ALLOCATION FUND

- --------------------------------------------------------------------------------
                              VALUATION OF SHARES
- --------------------------------------------------------------------------------
 
Each Class' net asset value per share is calculated by      , the Fund's
custodian, on each day, Monday through Friday, except that net asset value is
not computed on a day in which no orders to purchase, sell, exchange or redeem
Fund shares have been received, any day on which there is not sufficient trading
in the Fund's portfolio securities that the Fund's net asset values per share
might be materially affected by changes in the value of such portfolio
securities or on days on which the NYSE is not open for trading. The NYSE is
currently scheduled to be closed on New Year's Day, Presidents' Day, Good
Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas,
and on the preceding Friday when one of those holidays falls on a Saturday or on
the subsequent Monday when one of those holidays falls on a Sunday.

Net asset value per share of a Class is determined as of the close of regular
trading on the NYSE, and is computed by dividing the value of the Fund's net
assets attributable to that Class by the total number of shares outstanding of
that Class. Generally, the Fund's investments are valued at market value or, in
the absence of a market value, at fair value as determined by or under the
direction of the Trustees.
 
A security that is primarily traded on a stock exchange is valued at the last
sale price on that exchange or, if no sales occurred during the day, at the
current quoted bid price. Short-term investments that mature in 60 days or less
are valued on the basis of amortized cost (which involves valuing an investment
at its cost and, thereafter, assuming a constant amortization to maturity of any
discount or premium, regardless of the effect of fluctuating interest rates on
the market value of the investment) when the Board of Trustees has determined
that amortized cost represents fair value. An option that is written by the Fund
is generally valued at the last sale price or, in the absence of the last sale
price, the last offer price. An option that is purchased by the Fund is
generally valued at the last sale price or, in the absence of the last sale
price, the last bid price. The value of a futures contract is equal to the
unrealized gain or loss on the contract that is determined by marking the
contract to the current settlement price for a like contract on the valuation
date of the futures contract. A settlement price may not be used if the market
makes a limit move with respect to a particular futures contract or if the
securities underlying the futures contract experience significant price
fluctuations after the determination of the settlement price. When a settlement
price cannot be used, futures contracts will be valued at their fair market
value as determined by or under the direction of the Board of Trustees.
 
- --------------------------------------------------------------------------------
                                   MANAGEMENT
- --------------------------------------------------------------------------------
 
The Trust's board of trustees, as part of its overall management responsibility,
oversees various organizations responsible for the Fund's day-to-day management.
Mitchell Hutchins, the Fund's investment adviser and administrator, supervises
all aspects of the Fund's operations. Mitchell Hutchins receives a monthly fee
for its services, computed daily and payable monthly, at an annual rate of .50%
of the Fund's average daily net assets on assets up to but not including $250
million and .45% thereafter.
 
The Fund incurs other expenses and, for the fiscal year ended August 31, 1995,
the Fund's total expenses for its Class A and Class C shares, stated as a
percentage of average net assets were 1.46% and 2.22%, respectively.
 
Mitchell Hutchins is located at 1285 Avenue of the Americas, New York, New York
10019. It is a wholly owned subsidiary of PaineWebber, which is in turn a wholly
owned subsidiary of Paine Webber Group Inc., a publicly owned financial

services holding company. As of November 30, 1995, Mitchell Hutchins was adviser
or sub-adviser of 38 investment companies with 70 separate portfolios and
aggregate assets of over $29.6 billion.
 
As the Fund's investment adviser, Mitchell Hutchins manages the Fund's portfolio
in accordance with the investment objective and stated policies of the Fund and
makes investment decisions for the Fund. Mitchell Hutchins also provides the
Fund with investment officers who are authorized by the Trustees to determine
purchases and sales of securities on behalf of the Fund and employs a
professional staff of portfolio managers who draw upon a variety of sources for
research information for the Fund.
 
T. Kirkham Barneby is responsible for the asset allocation decisions for the
Fund. Mr. Barneby is a Managing Director and Chief Investment
Officer -- Quantitative Investments of Mitchell Hutchins. Mr. Barneby rejoined
Mitchell Hutchins in 1994, after being with Vantage Global Management for one
year. During the eight years that Mr. Barneby was previously with Mitchell
Hutchins, he was Senior Vice President responsible for quantitative management
and asset allocation models. Before joining Mitchell Hutchins, Mr. Barneby
served as Director of Pension Investment Strategy at the Continental Group in
Stamford, Connecticut and has held positions in the Economics Department at both
Citibank, N.A. and Merrill Lynch.
 
Although investment decisions for the Fund are made independently from those of
the other accounts managed by Mitchell Hutchins, investments of the type the
Fund may make may also be made by those other accounts. When the Fund and one or
more other accounts managed by Mitchell Hutchins are prepared to invest in, or
desire to dispose of, the same security, available investments or opportunities
for sales are allocated in a manner believed by Mitchell Hutchins to be
equitable to each. In some cases, this procedure may adversely affect the price
paid or received by the Fund or the size of the position obtained or disposed of
by the Fund.
 
Mitchell Hutchins investment personnel may engage in securities transactions for
their own accounts pursuant to each firm's code of ethics that establishes
procedures for personal investing and restricts certain transactions.
 
DISTRIBUTION ARRANGEMENTS.  Mitchell Hutchins is the distributor of Fund shares
and has appointed PaineWebber as the exclusive dealer for the sale of those
shares. Under separate plans of distribution pertaining to the Class A shares,
Class B shares and Class C shares ('Class A Plan,' 'Class B Plan' and 'Class C
Plan,' collectively, 'Plans'), the Fund pays Mitchell Hutchins monthly service
fees at the annual rate of 0.25% of the average daily net assets of each Class
of shares. The Fund pays Mitchell Hutchins monthly distribution fees at the
annual rate of 0.75% of the average daily net assets of the Class B shares and
Class C shares.
 
Under all three Plans, Mitchell Hutchins uses the service fees primarily to pay
PaineWebber for shareholder servicing, currently at the annual rate of 0.25% of
the aggregate investment amounts maintained in the Fund by PaineWebber clients.
PaineWebber passes on a portion of these fees to its investment executives to
compensate them for shareholder servicing that they perform and retains the
remainder to offset its own expenses in servicing and maintaining shareholder
accounts. These expenses may include costs of the PaineWebber branch office in
which the investment executive is based, such as rent, communications equipment,
employee salaries and other overhead costs.
 
Mitchell Hutchins uses the distribution fees under the Class B and Class C Plans
to offset the commissions it pays to PaineWebber for selling the Fund's Class B
and Class C shares. PaineWebber passes on to its investment executives a portion
of these commissions and retains the remainder to offset its expenses in selling
Class B and Class C shares. These expenses may include the branch office costs
noted above. In addition, Mitchell Hutchins uses the distribution fees under the
Class B and Class C Plans to offset the Fund's marketing costs attributable to
such Classes, such as preparation of sales literature, advertising and printing
and distributing prospectuses and other shareholder materials to prospective
investors. Mitchell Hutchins also may use the distribution fees to pay
additional compensation to PaineWebber and other costs allocated to Mitchell
Hutchins' and PaineWebber's distribution activities, including employee
salaries, bonuses and other overhead expenses.
 
Mitchell Hutchins expects that, from time to time, PaineWebber will pay
shareholder servicing fees and sales commissions to its investment executives at
the time of sale of Class C shares of the Fund. If PaineWebber makes such
payments, it will retain the service and distribution fees on

Class C shares until it has been reimbursed for its sales commissions and
thereafter will pass a portion of the service and distribution fees on Class C
shares on to its investment executives.
 
Mitchell Hutchins receives the proceeds of the initial sales charge paid upon
the purchase of Class A shares and the contingent deferred sales charge paid
upon certain redemptions of Class B shares, and may use these proceeds for any
of the distribution expenses described above. See 'Purchases'.
 
During the period they are in effect, the Plans and related distribution
contracts pertaining to each Class of shares ('Distribution Contracts') obligate
the Fund to pay service and distribution fees to Mitchell Hutchins as
compensation for its service and distribution activities, not as reimbursement
for specific expenses incurred. Thus, even if Mitchell Hutchins' expenses exceed
its service or distribution fees, the Fund will not be obligated to pay more
than those fees and, if Mitchell Hutchins' expenses are less than such fees, it
will retain its full fees and realize a profit. The Fund will pay the service
and distribution fees to Mitchell Hutchins until either the applicable Plan or
Distribution Contract is terminated or not renewed. In that event, Mitchell
Hutchins' expenses in excess of service and distribution fees received or
accrued through the termination date will be Mitchell Hutchins' sole
responsibility and not obligations of the Fund. In their annual consideration of
the continuation of the Fund's Plans, the board of trustees will review the Plan
and Mitchell Hutchins' corresponding expenses for each Class separately from the
Plans and corresponding expenses for the other two Classes.

                            PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
The Fund performs a standardized computation of annualized total return and may
show this return in advertisements or promotional materials. Standardized return
shows the change in value of an investment in the Fund as a steady compound
annual rate of return. Actual year-by-year returns fluctuate and may be higher
or lower than standardized return. Standardized return for Class A shares
reflects deduction of the Fund's maximum initial sales charge at the time of
purchase, and standardized return for Class B and Class C shares reflect
deduction of the applicable contingent deferred sales charge imposed on a
redemption of shares held for the period. One-, five- and ten-year periods will
be shown, unless the class has been in existence for a shorter period. Total
return calculations assume reinvestment of dividends and other distributions.
 
The Fund may use other total return presentations in conjunction with
standardized return. These may cover the same or different periods as those used
for standardized return and may include cumulative returns, average annual
rates, actual year-by-year rates or any combination thereof. Non-standardized
return does not reflect initial or contingent deferred sales charges and would
be lower if such charges were included.
 
The Fund will include performance data for Class A, Class B and Class C shares
in any advertisements or promotional materials including Fund performance data.
Total return and yield information reflects past performance and does not
necessarily indicate future results. Investment return and principal values will
fluctuate, and proceeds upon redemption may be more or less than a shareholder's
cost.

PAINEWEBBER   TACTICAL ALLOCATION FUND


- --------------------------------------------------------------------------------
                              GENERAL INFORMATION
- --------------------------------------------------------------------------------
 
ORGANIZATION OF THE TRUST.  The Trust was formed as a business trust pursuant to
a Declaration of Trust, as amended from time to time (the 'Declaration'), under
the laws of The Commonwealth of Massachusetts on March 28, 1991. The Fund
commenced operations on July 22, 1992. The Declaration authorizes the Trust's
Board of Trustees to create separate series, and within each series separate
Classes, of an unlimited number of shares of beneficial interest, par value
$.001 per share. As of the date of this Prospectus, the Trustees have
established several such series, representing interests in the Fund described in
this Prospectus and in several other series.
 
When issued, Fund shares will be fully paid and non-assessable. Shares are
freely transferable and have no pre-emptive, subscription or conversion rights.
Each Class represents an identical interest in the Fund's investment portfolio.
As a result, the Classes have the same rights, privileges and preferences,
except with respect to: (1) the designation of each Class; (2) the effect of the
respective sales charges, if any, for each Class; (3) the distribution and/or
service fees, if any, borne by each Class; (4) the expenses allocable
exclusively to each Class; (5) voting rights on matters exclusively affecting a
single Class; and (6) the exchange privilege of each Class. The Board of
Trustees does not anticipate that there will be any conflicts among the
interests of the holders of the different Classes. The Trustees, on an ongoing
basis, will consider whether any conflict exists and, if so, take appropriate
action. Certain aspects of the shares may be changed, upon notice to Fund
shareholders, to satisfy certain tax regulatory requirements, if the change is
deemed necessary by the Trustees.
 
Shareholders of the Fund are entitled to one vote for each full share held and
fractional votes for fractional shares held. Voting rights are not cumulative
and, as a result, the holders of more than 50% of the aggregate shares of the
Trust may elect all of the Trustees. Generally, shares of the Trust will be
voted on a Trust-wide basis on all matters except those affecting only the
interests of one series, such as the Fund's management and investment advisory
agreement. In turn, shares of the Fund will be voted on a Fund-wide basis on all
matters except those affecting only the interests of one Class, such as the
terms of the Plan as it relates to a Class.
 
The Trust intends to hold no annual meetings of shareholders for the purpose of
electing Trustees unless, and until such time as, less 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 Trust may
remove a Trustee through a declaration in writing or by vote cast in person or
by proxy at a meeting called for that purpose. A meeting will be called for the
purpose of voting on the removal of a Trustee at the written request of holders
of 10% of the Trust's outstanding shares. Shareholders of the Fund who satisfy
certain criteria will be assisted by the Trust in communicating with other
shareholders in seeking the holding of the meeting.
 
To avoid additional operating costs and for investor convenience, the Fund does
not issue share certificates. Ownership of the Fund's shares is recorded on a
stock register by the Transfer Agent and shareholders have the same rights of
ownership with respect to such shares as if certificates had been issued.
 
CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, One Heritage
Drive, North Quincy, Massachusetts 02171, is the custodian of the Fund's assets.
PFPC Inc., a subsidiary of PNC Bank, National Association, whose principal
business address is 400 Bellevue Parkway, Wilmington, Delaware 19809, is the
Fund's transfer and dividend disbursing agent.
 
CONFIRMATIONS AND STATEMENTS.  Shareholders receive confirmations of purchases
and redemptions of Fund shares. PaineWebber clients receive statements at least
quarterly that report their Fund activity and consolidated year-end statements
that show all Fund transactions for that year. Shareholders who are not
PaineWebber clients receive quarterly statements from the Transfer Agent.
Shareholders also receive audited annual and unaudited semi-annual financial
statements of the Fund.

                      INVESTMENT POLICIES AND RESTRICTIONS

 
     The  Prospectus  discusses the  investment objective  of  the Fund  and the
policies employed in achieving that  objective. Supplemental information is  set
out  below concerning certain  of the securities and  other instruments in which
the Fund may invest, the investment techniques and strategies that the Fund  may
utilize  and  certain  risks  involved with  those  investments,  techniques and
strategies.
 
INVESTMENT TECHNIQUES AND STRATEGIES
 
     OPTIONS. To the extent required by the laws of certain states, the Fund may
not be  permitted  to  commit more  than  5%  of its  assets  to  premiums  when
purchasing call and put options on securities. Should these state laws change or
should  the Fund obtain a waiver of  their application, the Fund may commit more
than 5%  of its  assets to  premiums when  purchasing call  and put  options  on
securities.  In addition,  should the  Trust determine  that a  commitment is no
longer in the best interests  of the Fund and  its shareholders, the Trust  will
revoke  the commitment by terminating the sale of the Fund's shares in the state
involved.
 
     FUTURES CONTRACTS. The Fund may trade stock index futures contracts to  the
extent  permitted  under  rules  and interpretations  adopted  by  the Commodity
Futures Trading  Commission  (the  'CFTC'). U.S.  futures  contracts  have  been
designed  by exchanges  that have been  designated as 'contract  markets' by the
CFTC, and must be executed through  a futures commission merchant, or  brokerage
firm,  that is a member of the relevant contract market. Futures contracts trade
on a number of contract markets,  and, through their clearing corporations,  the
exchanges guarantee performance of the contracts as between the clearing members
of the exchange.
 

<PAGE>
<PAGE>
     The  purpose  of trading  futures  contracts is  to  protect the  Fund from
fluctuations in  value  of its  investment  securities without  its  necessarily
buying  or selling  the securities. Because  the value of  the Fund's investment
securities will exceed the value of the  futures contracts sold by the Fund,  an
increase  in the  value of  the futures contracts  could only  mitigate, but not
totally offset, the decline in the value of the Fund's assets. No  consideration
is  paid or received by the Fund upon trading a futures contract. Upon trading a
futures contract, the Fund is required  to deposit in a segregated account  with
its  custodian an  amount of  cash, short-term U.S.  Treasury Bills  or Notes or
other high-grade, short-term money market instruments equal to approximately  1%
to  10% of the contract amount (this amount is subject to change by the exchange
on which the contract is  traded and brokers may  charge a higher amount).  This
amount  is known as 'initial margin' and is  in the nature of a performance bond
or good  faith  deposit on  the  contract that  is  returned to  the  Fund  upon
termination  of the futures contract,  assuming that all contractual obligations
have been  satisfied; the  broker will  have  access to  amounts in  the  margin
account  if  the  Fund fails  to  meet its  contractual  obligations. Subsequent
payments, known as 'variation margin,' to and from the broker, are made daily as
the price of the securities  underlying the futures contract fluctuates,  making
the  long and short positions  in the futures contract  more or less valuable, a
process known as 'marking-to-market.' At any  time prior to the expiration of  a
futures  contract, the Fund may elect to  close a position by taking an opposite
position, which will operate  to terminate the Fund's  existing position in  the
contract.
 
     Positions  in futures contracts may  be closed out only  on the exchange on
which they were undertaken (or through  a linked exchange). No secondary  market
for  futures contracts currently exists, and  although the Fund intends to trade
futures contracts only if an active market for them exists, no assurance can  be
given that an active market will exist for the contracts at any particular time.
Most  futures exchanges  limit the  amount of  fluctuation permitted  in futures
contract prices  during a  single trading  day. Once  the daily  limit has  been
reached  in a particular contract, no trades may  be made on that day at a price
beyond that limit. Prices for futures contracts may move to the daily limit  for
several  consecutive trading days with little  or no trading, thereby preventing
prompt liquidation of futures positions  and subjecting the Fund to  substantial
losses.  In that  case, and in  the event  of adverse price  movements, the Fund
would be  required to  make daily  cash payments  of variation  margin. In  such
circumstances,  an increase in the value of the portion of the Fund's securities
being hedged, if any, may partially  or completely offset losses on the  futures
contract.
 
     OPTIONS  ON FUTURES CONTRACTS. The Fund may purchase and write put and call
options on stock index future  contracts that are traded  on a U.S. exchange  or
board  of trade or a  foreign exchange, to the  extent permitted under rules and
interpretations of the CFTC,  as a hedge against  changes in market  conditions,
and  may  enter  into closing  transactions  with  respect to  those  options to
terminate existing  positions.  No  assurance  can be  given  that  the  closing
transactions can be effected.
 

     LENDING  PORTFOLIO SECURITIES.  The Fund  may lend  portfolio securities to
well-known and recognized  U.S. and  foreign brokers, dealers  and banks.  These
loans,  if and when  made, may not exceed  30% of the value  of the Fund's total
assets. The Fund's loans of securities  will be collateralized by cash,  letters
of  credit  or securities  issued  and guaranteed  by  the U.S.  Government, its
agencies, authorities or instrumentalities  ('Government Securities'). The  cash
or instruments collateralizing the Fund's loans of securities will be maintained
at  all  times in  a segregated  account with  the Fund's  custodian, or  with a
designated sub-custodian, in  an amount  at least  equal to  the current  market
value  of the loaned securities. From  time to time, the Fund  may pay a part of
the interest earned from  the investment of  collateral received for  securities
loaned  to  the borrower  and/or a  third  party that  is unaffiliated  with the

 
                                       2
 

<PAGE>
<PAGE>
Fund and  is acting  as a  'finder.' The  Fund will  comply with  the  following
conditions whenever it loans securities: (1) the Fund must receive at least 100%
cash  collateral or  equivalent securities from  the borrower;  (2) the borrower
must increase the collateral whenever the market value of the securities  loaned
rises  above the level of the collateral; (3) the Fund must be able to terminate
the loan at any time; (4) the Fund must receive reasonable interest on the loan,
as well  as  any  dividends,  interest or  other  distributions  on  the  loaned
securities,  and  any  increase in  market  value;  (5) the  Fund  may  pay only
reasonable custodian fees in connection with the loan; and (6) voting rights  on
the  loaned securities may pass to the borrower except that, if a material event
adversely affecting the investment in the loaned securities occurs, the  Trust's
Board  of Trustees  must terminate  the loan  and regain  the right  to vote the
securities.
 
     WHEN-ISSUED AND  DELAYED-DELIVERY  SECURITIES.  When the  Fund  engages  in
when-issued  or delayed-delivery securities transactions, it relies on the other
party to consummate the trade. Failure of the seller to do so may result in  the
Fund's  incurring a loss or missing an  opportunity to obtain a price considered
to be advantageous.
 
INVESTMENT RESTRICTIONS
 
     Investment restrictions numbered 1  through 10 below  have been adopted  by
the Trust as fundamental policies with respect to the Fund. Under the Investment
Company  Act of 1940, as amended (the  '1940 Act'), a fundamental policy may not
be changed without the vote of  a majority of the outstanding voting  securities
of  the Fund, as  defined in the  1940 Act. Investment  restrictions numbered 11
through 17 may  be changed  by a  vote of  a majority  of the  Trust's Board  of
Trustees at any time.
 
     Under  the investment restrictions adopted by the Trust with respect to the
Fund:
 
          1. The  Fund  will  not purchase  securities  (other  than  Government
     Securities)  of any issuer if, as a result of the purchase, more than 5% of
     the value of the Fund's total assets would be invested in the securities of
     the issuer, except that up to 25%  of the value of the Fund's total  assets
     may be invested without regard to this 5% limitation.
 
          2.  The Fund will not purchase more  than 10% of the voting securities
     of any one issuer, or more than 10%  of the securities of any class of  any
     one  issuer, except  that this limitation  is not applicable  to the Fund's
     investments in Government Securities,  and up to 25%  of the Fund's  assets
     may be invested without regard to these 10% limitations.
 
          3.  The Fund will  not borrow money,  except that the  Fund may borrow
     from banks for temporary or emergency (not leveraging) purposes,  including
     the  meeting  of redemption  requests and  cash  payments of  dividends and
     distributions that  might otherwise  require  the untimely  disposition  of
     securities, in an amount not to exceed 20% of the value of the Fund's total
     assets  (including the amount  borrowed) valued at  market less liabilities
     (not including the  amount borrowed)  at the  time the  borrowing is  made.
     Whenever borrowings exceed 5% of the value of the total assets of the Fund,
     the Fund will not make any additional investments.
 
          4.  The  Fund will  not lend  money to  other persons,  except through
     purchasing debt obligations, lending portfolio securities in an amount  not
     to  exceed  30% of  the  Fund's assets  taken  at value  and  entering into
     repurchase agreements.

          5. The Fund will  invest no more  than 25% of the  value of its  total
     assets in securities of issuers in any one industry.
 
          6.  The Fund will  not purchase securities on  margin, except that the
     Fund may  obtain any  short-term  credits necessary  for the  clearance  of
     purchases  and sales of  securities. For purposes  of this restriction, the
     deposit or  payment  of initial  or  variation margin  in  connection  with
     futures  contracts or options on futures contracts will not be deemed to be
     a purchase of securities on margin.
 
          7. The Fund  will not  make short sales  of securities  or maintain  a
     short position, unless at all times when a short position is open, the Fund
     owns  an equal amount  of the securities or  securities convertible into or
     exchangeable for, without payment of any further consideration,  securities
     of the same issue as, and equal in amount to, the securities sold short.
 
          8.  The Fund  will not  purchase or  sell real  estate or  real estate
     limited partnership interests, except that  the Fund may purchase and  sell
     securities  of  companies that  deal in  real estate  or interests  in real
     estate.
 
          9. The  Fund  will  not  purchase or  sell  commodities  or  commodity

          10. The Fund will not act as an underwriter of securities, except that
     the Fund  may  acquire securities  under  circumstances in  which,  if  the
     securities  were sold, the  Fund might be  deemed to be  an underwriter for
     purposes of the 1933 Act.
 
          11. The Fund will not  invest in oil, gas  or other mineral leases  or
     exploration or development programs.
 
          12.  The Fund  will not purchase  any security, other  than a security
     acquired pursuant to a plan of  reorganization or an offer of exchange,  if
     as  a result of  the purchase (a) the  Fund would own  any securities of an
     open-end investment company or more than 3% of the total outstanding voting
     stock of any closed-end investment company or (b) more than 5% of the value
     of the Fund's total assets  would be invested in  securities of any one  or
     more closed-end investment companies.
 
          13.  The Fund  will not  participate on  a joint  or joint-and-several
     basis in any securities trading account.

     outstanding  securities of the  company and together  they own beneficially
     more than 5% of the securities.
 
          17. The Fund will not invest in warrants (other than warrants acquired
     by the Fund  as part of  a unit or  attached to securities  at the time  of
     purchase)  if, as a result, the investments (valued at the lower of cost or
     market) would exceed 5% of the value of the Fund's net assets of which  not
     more  than 2%  of the  Fund's net  assets may  be invested  in warrants not
     listed on a recognized foreign or domestic stock exchange.

               INVESTMENT ADVISORY AND DISTRIBUTION ARRANGEMENTS

 

     The Fund  bears  all  expenses  incurred in  its  operation  that  are  not
specifically  assumed by  Mitchell Hutchins. General  expenses of  the Trust not
readily identifiable as belonging  to the Fund are  allocated among the Fund  or
the  Trust's other series by or under the  direction of the board of trustees in
such manner as the board deems to  be fair and equitable. Expenses borne by  the
Fund  include the following (or the Fund's share of the following): (1) the cost
(including brokerage commissions) of  securities purchased or  sold by the  Fund
and  any  losses  incurred in  connection  therewith,  (2) fees  payable  to and
expenses incurred on behalf of the Fund by Mitchell Hutchins, (3) organizational
expenses, (4)  filing  fees  and  expenses  relating  to  the  registration  and
qualification  of  the  Fund's shares  and  the  Trust under  federal  and state
securities laws and  maintenance of such  registrations and qualifications,  (5)
fees and salaries payable to trustees who are not interested persons (as defined
in the 1940 Act) of the Trust 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, uncollectable items  of deposit and  other insurance or fidelity
bonds, (9) any costs, expenses or

losses arising  out of  a liability  of or  claim for  damages or  other  relief
asserted  against the Trust  or the Fund  for violation of  any law, (10) legal,
accounting and auditing expenses,  including legal fees  of special counsel  for
the  independent trustees, (11) charges of custodians, transfer agents and other
agents, (12) costs of preparing share certificates, (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 existing shareholders, (14)
any  extraordinary  expenses  (including  fees  and  disbursements  of  counsel)
incurred  by the Trust or  the Fund, (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 trustees  and
officers and (18) costs of mailing, stationery and communications equipment.

 

     For  the fiscal years ended August 31, 1995, August 31, 1994 and August 31,
1993, the Trust paid (or  accrued) management fees with  respect to the Fund  of
$279,950; $505,878; and $419,426, respectively, to the Fund's investment adviser
and administrator during those periods.

 

     Mitchell  Hutchins has agreed that, if in  any fiscal year of the Fund, the
aggregate expenses  of  the  Fund  (including  management  fees,  but  excluding
interest,  taxes, brokerage and, with the prior written consent of the necessary
state  securities  commissions,  extraordinary  expenses)  exceed  the   expense
limitation  of any state  having jurisdiction over  the Trust, Mitchell Hutchins
will reimburse  the Trust  for the  excess expense.  This expense  reimbursement
obligation  is  limited  to the  amount  of  Mitchell Hutchins'  fees  under its
respective agreement  with  the  Trust  in respect  of  the  Fund.  Any  expense
reimbursement  will be estimated, reconciled and paid  on a monthly basis. As of
the date of this Statement of Additional Information, the most restrictive state
expense limitation applicable to the Fund requires reimbursement of expenses  in
any year that the Fund's expenses subject to the limitation exceed 2 1/2% of the
first $30 million of the average daily value of the Fund's net assets, 2% of the
next  $70 million of the average daily value of the Fund's net assets and 1 1/2%
of the remaining average daily  value of the Fund's  net assets. For the  fiscal
year ended August 31, 1995, the Fund's expenses did not exceed such limitations.

 

     Under  its  agreement  with the  Trust  in  respect of  the  Fund, Mitchell
Hutchins will not be liable for any error  of judgment or mistake of law or  for
any  loss suffered by the Trust with respect  to the Fund in connection with the
matters to which the agreement relates, except for 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  the
agreement.

 

     Mitchell Hutchins personnel may invest in securities for their own accounts
pursuant  to  a  code  of  ethics that  describes  the  fiduciary  duty  owed to
shareholders of  the  PaineWebber  mutual funds  and  other  Mitchell  Hutchins'
advisory  accounts by all Mitchell  Hutchins' directors, officers and employees,
establishes  procedures   for   personal   investing   and   restricts   certain
transactions.  For example,  employee accounts  generally must  be maintained at
PaineWebber, personal  trades  in  most  securities  require  pre-clearance  and
short-term  trading and participation in  initial public offerings generally are
prohibited. In addition, the code of  ethics puts restrictions on the timing  of
personal  investing  in relation  to trades  by  PaineWebber and  other Mitchell
Hutchins advisory clients.

DISTRIBUTION ARRANGEMENTS

 

     Mitchell Hutchins serves as the distributor of the Fund's shares on a  best
efforts  basis.  Under  a  Shareholder  Servicing  and  Distribution  Plans (the
'Plans') adopted by the Trust  with respect to the  Fund pursuant to Rule  12b-1
under  the 1940 Act, the Trust pays Mitchell Hutchins monthly fees calculated at
the aggregate annual rates of .25%, 1.00%  and 1.00% of the value of the  Fund's
average  daily net assets attributed to Class A shares, Class B shares and Class
C shares, respectively.  Under their  terms, the  Plans continues  from year  to
year, so long as their continuance is approved annually by vote of the Trustees,
including a majority of the Trustees who are not interested persons of the Trust
and  who have no direct  or indirect financial interest  in the operation of the
Plans (the 'Independent  Trustees'). The Plans  may not be  amended to  increase
materially the amount to be spent for the services provided by Mitchell Hutchins
without Fund shareholder approval, and all material amendments of the Plans also
must be approved by the Trustees in the manner described above. The Plans may be
terminated  with respect to a  Class at any time, without  penalty, by vote of a
majority of  the  Independent  Trustees or  by  a  vote of  a  majority  of  the
outstanding  voting securities (as  defined in the 1940  Act) represented by the
Class on not more than 30 days' written notice to Mitchell Hutchins.

 

     Pursuant to  the  Plans,  Mitchell  Hutchins  provides  the  Trustees  with
periodic  reports of amounts expended under the  Plans and the purpose for which
the expenditures were made.  The Trustees believe  that the Fund's  expenditures
under  the  Plans benefit  the  Fund and  its  shareholders by  providing better
shareholder services  and  by  facilitating the  distribution  of  shares.  With
respect  to Class A shares, for the  fiscal year ended August 31, 1995, Mitchell
Hutchins received $4,345 from the Fund. During such fiscal year, it is estimated
that Mitchell  Hutchins  and PaineWebber  spent  $300 on  advertising,  $300  on
printing  and mailing of prospectuses to other than current shareholders, $2,068
on commission credits to  branch offices for  payments of shareholder  servicing
compensation  to investment executives  and $1,685 on  overhead and other branch
office distribution or shareholder  servicing-related expenses. With respect  to
Class  C shares, for  the fiscal year  ended August 31,  1995, Mitchell Hutchins
received $512,944 from the Fund. During  such fiscal year, it is estimated  that
Mitchell  Hutchins and PaineWebber  spent $122,300 on  advertising, $122,300 was
spent  on  printing  and   mailing  of  prospectuses   to  other  than   current
shareholders,  $155,646 was  spent on commission  credits to  branch offices for
payments of  commissions and  shareholder servicing  compensation to  investment
executives   and  $112,730  was  spent  on  overhead  and  other  branch  office
distribution or shareholder servicing-related expenses.  No Class B shares  were
outstanding  during  that period.  The term  'overhead  and other  branch office
distribution or  shareholder  servicing-related  expenses'  represents  (1)  the
expenses  of operating PaineWebber's branch offices  in connection with the sale
of Fund shares or servicing of shareholder accounts, including lease costs,  the
salaries  and  employee  benefits  of operations  and  sales  support personnel,
utility costs, communications costs  and the costs  of stationery and  supplies,
(2) the costs of client sales seminars, (3) travel expenses of mutual fund sales
coordinators  to  promote  the sale  of  Fund  shares and  (4)  other incidental
expenses relating to branch promotion of Fund sales.

 

                             PORTFOLIO TRANSACTIONS

 

     Decisions to buy  and sell  securities for the  Fund are  made by  Mitchell
Hutchins,  subject to review  by the Trust's Board  of Trustees. Transactions on
domestic stock exchanges and some foreign stock exchanges involve the payment of
negotiated brokerage commissions. On exchanges on which

 
                                       9
 

<PAGE>
<PAGE>

commissions are negotiated, the  cost of transactions  may vary among  different
brokers. On most foreign exchanges, commissions are generally fixed.

 

     Subject to policies established by the Board of Trustees, Mitchell Hutchins
is  responsible for the  execution of the Fund's  portfolio transactions and the
allocation of  brokerage  transactions.  In  executing  portfolio  transactions,
Mitchell Hutchins seeks to obtain the best net results for the Fund, taking into
account  such factors as price (including the applicable brokerage commission or
dealer  spread),  size  of  order,  difficulty  of  execution  and   operational
facilities  of the firm involved. Generally, bonds  are traded on the OTC market
on a 'net' basis  without a stated commission  through dealers acting for  their
own account and not as brokers. Prices paid to dealers in principal transactions
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  the
time. For the fiscal years ended August 31, 1995, August 31, 1994 and August 31,
1993,  the Fund paid  $82,091; $56,965; and  $58,975, respectively, in aggregate
brokerage commissions.

 

     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, brokerage transactions may be
conducted through Mitchell  Hutchins or its  affiliates, including  PaineWebber.
The  Trust'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  and  its  affiliates  are  reasonable  and  fair.  Specific
provisions in the Advisory Contract authorize  Mitchell Hutchins and any of  its
affiliates  that  are  members  of  a  national  securities  exchange  to effect
portfolio transactions for the Fund on such exchange and to retain  compensation
in connection with such transactions. Any such transactions will be effected and
related  compensation paid only  in accordance with  applicable SEC regulations.
For the  fiscal  year  ended August  31,  1995,  the Fund  paid  [NO]  brokerage
commissions to PaineWebber.

 

     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  Fund's  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 the Fund  and subject to the review of  the
board  of trustees, Mitchell  Hutchins may cause  the Fund to  purchase and sell
portfolio securities  through  brokers  who  provide  the  Fund  with  research,
analysis, advice and similar services. In return for such services, the Fund may
pay  to those brokers a higher commission  than may be charged by other brokers,
provided that Mitchell Hutchins determines in good faith that such commission is
reasonable in terms  either of  that particular  transaction or  of the  overall
responsibility  of Mitchell Hutchins to the Fund  and its other clients and that
the total commissions paid  by the Fund  will be reasonable  in relation to  the
benefits  to  the  Fund  over  the  long  term.  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,  Mitchell 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

 
                                       10
 

<PAGE>
<PAGE>

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  provided  research  or execution  services.  These  procedures include
Mitchell Hutchins receiving  multiple quotes from  dealers before executing  the
transaction on an agency basis.

 

     Research services furnished by the brokers or dealers through which or with
which  the Fund effects securities transactions may be used by Mitchell Hutchins
in advising other funds or accounts and, conversely, research services furnished
to Mitchell Hutchins  by brokers or  dealers in connection  with other funds  or
accounts  that Mitchell  Hutchins advises  may be  used by  Mitchell Hutchins in
advising the  Fund.  Information and  research  received from  such  brokers  or
dealers  will be in addition to, and not in lieu of, the services required to be
performed by Mitchell Hutchins under the Management Agreement.

 

     Investment decisions for the Fund and for other investment accounts managed
by Mitchell Hutchins 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 the Fund 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 Fund and such other account(s) as
to amount according to  a formula deemed  equitable to the  Fund and such  other
account(s).  While in some  cases this practice could  have a detrimental effect
upon the price or value of the security as far as the Fund 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 Fund.

 

     The  Fund will not  purchase securities in  underwritings in which Mitchell
Hutchins or any of  its affiliates is  a member of  the underwriting or  selling
group,  except  pursuant to  procedures adopted  by  the Corporation's  board of
directors 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 or any affiliate thereof  not
participate in or benefit from the sale to the Fund.

 

     PORTFOLIO  TURNOVER. The portfolio turnover  rate is calculated by dividing
the lesser  of the  Fund'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  in the portfolio during the year.  For the fiscal years ended August
31, 1995 and  August 31,  1994, the  portfolio turnover  rate for  the Fund  was
53.02%  and 4.17%, respectively. The higher  turnover for the most recent fiscal
year was due  to reallocations  during that period  of the  Fund's portfolio  in
accordance with the Fund's systematic asset allocation strategy.

                         INFORMATION AND OTHER SERVICES

 

     COMBINED  PURCHASE  PRIVILEGE --  CLASS  A SHARES.  Investors  and eligible
groups of related Fund investors may combine purchases of Class A shares of  the
Fund with concurrent purchases of Class A shares of any other PaineWebber mutual
fund  and thus take  advantage of the  reduced sales charges  for Class A shares
indicated in the  table of  sales charges in  the Prospectus.  The sales  charge
payable on the

 
                                       11
 

<PAGE>
<PAGE>

purchase  of Class A shares of the Funds  and Class A shares of such other funds
will be at the rates applicable to  the total amount of the combined  concurrent
purchases.

 

     An   'eligible  group  of  related  Fund  investors'  can  consist  of  any
combination of the following:

 

          (a) an individual, that individual's spouse, parents and children;

 

          (b) an  individual  and  his  or  her  Individual  Retirement  Account
     ('IRA');

 

          (c)  an individual (or eligible group  of individuals) and any company
     controlled by the individual(s) (a person,  entity or group that holds  25%
     or  more  of the  outstanding voting  securities of  a corporation  will be
     deemed to control the corporation, and  a partnership will be deemed to  be
     controlled by each of its general partners);

 

          (d)  an individual (or eligible group  of individuals) and one or more
     employee benefit plans of a company controlled by the individual(s);

 

          (e) an  individual (or  eligible  group of  individuals) and  a  trust
     created by the individual(s), the beneficiaries of which are the individual
     and/or the individual's spouse, parents or children;

 

          (f)  an individual and a Uniform Gifts to Minors Act/Uniform Transfers
     to Minors Act account created by the individual or the individual's spouse;
     or

 

          (g) an employer  (or a  group of related  employers) and  one or  more
     qualified  retirement  plans of  such  employer or  employers  (an employer
     controlling, controlled by or under common control with another employer is
     deemed related to that other employer).

 

     RIGHTS OF  ACCUMULATION  --  CLASS  A SHARES.  Reduced  sales  charges  are
available  through a right  of accumulation, under  which investors and eligible
groups of related Fund  investors (as defined above)  are permitted to  purchase
Class  A  shares  of the  Fund  among  related accounts  at  the  offering price
applicable to the total of (1) the  dollar amount then being purchased plus  (2)
an  amount equal to the then-current net asset value of the purchaser's combined
holdings of Class  A Fund shares  and Class  A shares of  any other  PaineWebber
mutual  fund.  The  purchaser  must  provide  sufficient  information  to permit
confirmation of his or her holdings, and the acceptance of the purchase order is
subject to  such confirmation.  The  right of  accumulation  may be  amended  or
terminated at any time.

 

     WAIVERS  OF SALES CHARGES -- CLASS B SHARES. Among other circumstances, the
contingent deferred sales charge on Class B shares of the Fund is waived where a
total or partial redemption is made within  one year following the death of  the
shareholder.  The contingent deferred sales charge waiver is available where the
decedent is either  the sole  shareholder or  owns the  shares with  his or  her
spouse as a joint tenant with right of survivorship. This waiver applies only to
redemption of shares held at the time of death.

 

     ADDITIONAL  EXCHANGE  AND  REDEMPTION  INFORMATION.  As  discussed  in  the
Prospectus, eligible  shares of  the Fund  may be  exchanged for  shares of  the
corresponding  Class of most  other PaineWebber mutual  funds. Shareholders will
receive at least 60 days' notice of any termination or material modification  of
the  exchange offer, except no  notice need be given  of an amendment whose only
material effect is to reduce  the exchange fee and no  notice need be given  if,
under  extraordinary






 
                                       12
 

<PAGE>
<PAGE>

circumstances,   either   redemptions  are  suspended  under  the  circumstances
described below or the Fund temporarily delays or ceases the sales of its shares
because it is unable to invest amounts effectively in accordance with the Fund's
investment objective, policies and restrictions.


     If  conditions  exist  which  make  cash  payments  undesirable,  each Fund
reserves the right  to honor  any request for  redemption by  making payment  in
whole  or in part in securities chosen by the Fund and valued in the same way as
they would be valued for purposes of  computing the Fund's net asset value.  Any
such  redemption in kind will be made with readily marketable securities, to the
extent available. If  payment is  made in  securities, a  shareholder may  incur
brokerage  expenses  in converting  those securities  into  cash. The  Trust has
elected, however, to be governed by Rule  18f-1 under the 1940 Act, under  which
the  Fund is  obligated to  redeem shares  solely in  cash up  to the  lesser of
$250,000 or 1% of the net asset value  of the Fund during any 90-day period  for
one  shareholder.  This  election  is irrevocable  unless  the  SEC  permits its
withdrawal. The Fund may suspend redemption  privileges 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 Fund's portfolio at the
time.

 

     SYSTEMATIC WITHDRAWAL PLAN. On or about the 15th of each month for  monthly
plans  and  on  or  about the  15th  of  the months  selected  for  quarterly or
semi-annual plans,  PaineWebber  will arrange  for  redemption by  the  Fund  of
sufficient   Fund  shares  to  provide   the  withdrawal  payment  specified  by
participants in the Fund's systematic withdrawal plan. The payment generally  is
mailed  approximately three business days  after the redemption date. Withdrawal
payments should not be considered  dividends, but redemption proceeds, with  the
tax  consequences described  under 'Dividends,  Distributions and  Taxes' in the
Prospectus. If periodic withdrawals  continually exceed reinvested dividends,  a
shareholder's  investment  may  be correspondingly  reduced.  A  shareholder may
change the amount of the systematic withdrawal or terminate participation in the
systematic withdrawal plan  at any  time without  charge or  penalty by  written
instructions  with signatures guaranteed to  PaineWebber or PFPC Inc. ('Transfer
Agent'). Instructions to participate in  the plan, change the withdrawal  amount
or  terminate participation in  the plan will  not be effective  until five days
after written  instructions  with  signatures guaranteed  are  received  by  the
Transfer  Agent.  Shareholders  may  request the  forms  needed  to  establish a
systematic  withdrawal  plan  from  their  PaineWebber  investment   executives,
correspondent firms or the Transfer Agent at 1-800-647-1568.

 

     REINSTATEMENT  PRIVILEGE -- CLASS A SHARES. As described in the Prospectus,
shareholders who have redeemed  Class A shares of  the Fund may reinstate  their
account  without  a sales  charge. Shareholders  may exercise  the reinstatement
privilege by notifying the Transfer Agent of such desire and forwarding a  check
for the amount to be purchased within 365 days after the date of redemption. The
reinstatement  will be made at the net asset value per share next computed after
the notice of  reinstatement and check  are received. The  amount of a  purchase
under  this reinstatement privilege  cannot exceed the  amount of the redemption
proceeds.  Gain  on  a   redemption  is  taxable   regardless  of  whether   the
reinstatement  privilege  is  exercised;  however,  a  loss  arising  out  of  a
redemption will not  be deductible  to the  extent the  redemption proceeds  are
reinvested,  if the  reinstatement privilege is  exercised within  30 days after
redemption, and an adjustment  will be made to  the shareholder's tax basis  for
the  shares acquired pursuant to the reinstatement  privilege. Gain or loss on a
redemption also will


 
                                       13
 

<PAGE>
<PAGE>


be adjusted  for federal  income tax  purposes by the amount of any sales charge
paid on Class A shares,  under the  circumstances and to the extent described in
'Dividends and Taxes' in the Prospectus.


     Reductions in or exemptions from the imposition of a sales load are due  to
the nature of the investors and/or the reduced sales efforts that will be needed
in obtaining such investments.

PAINEWEBBER RMA RESOURCE ACCUMULATION PLAN'SM';
PAINEWEBBER RESOURCE MANAGEMENT ACCOUNT'r' (RMA'r')

 

     Shares of the PaineWebber mutual funds (each a 'PW Fund' and, collectively,
the 'PW Funds') are available for purchase through the RMA Resource Accumulation
Plan  ('Plan')  by  customers of  PaineWebber  and its  correspondent  firms who
maintain Resource Management Accounts ('RMA accountholders'). The Plan allows an
RMA accountholder  to continually  invest in  one or  more of  the PW  Funds  at
regular intervals, with payment for shares purchased automatically deducted from
the client's RMA account. The client may elect to invest at monthly or quarterly
intervals and may elect either to invest a fixed dollar amount (minimum $100 per
period) or to purchase a fixed number of shares. A client can elect to have Plan
purchases executed on the first or fifteenth day of the month. Settlement occurs
three  Business Days (defined under 'Valuation of Shares') after the trade date,
and the  purchase price  of the  shares  is withdrawn  from the  investor's  RMA
account  on the settlement date from the  following sources and in the following
order: uninvested cash balances, balances in  RMA money market funds, or  margin
borrowing power, if applicable to the account.

 

     To  participate in the Plan, an investor must be an RMA accountholder, must
have made  an initial  purchase  of the  shares of  each  PW Fund  selected  for
investment  under the Plan (meeting  applicable minimum investment requirements)
and must complete and submit the RMA Resource Accumulation Plan Client Agreement
and Instruction Form available from PaineWebber. The investor must have received
a current prospectus for each PW Fund  selected prior to enrolling in the  Plan.
Information  about mutual fund positions  and outstanding instructions under the
Plan are noted on the RMA accountholder's account statement. Instructions  under
the  Plan may be  changed at any  time, but may  take up to  two weeks to become
effective.

 

     The terms of the Plan or an RMA accountholder's participation in the  Plan,
may  be  modified or  terminated at  any time.  It is  anticipated that,  in the
future, shares of other PW Funds and/or mutual funds other than the PW Funds may
be offered through the Plan.

 

  Periodic Investing and Dollar Cost Averaging.

 

     Periodic investing in the PW Funds  or other mutual funds, whether  through
the  Plan or  otherwise, helps  investors establish  and maintain  a disciplined
approach to  accumulating assets  over time,  de-emphasizing the  importance  of
timing  the market's highs and lows. Periodic investing also permits an investor
to take advantage  of 'dollar cost  averaging.' By investing  a fixed amount  in
mutual  fund shares at established intervals,  an investor purchases more shares
when the price  is lower  and fewer  shares when  the price  is higher,  thereby
increasing  his or her earning potential.  Of course, dollar cost averaging does
not guarantee a profit or protect against  a loss in a declining market, and  an
investor  should consider  his or  her financial  ability to  continue investing
through periods of low share prices.  However, over time, dollar cost  averaging
generally  results  in  a lower  average  original  investment cost  than  if an
investor invested a larger dollar amount in a mutual fund at one time.

  PaineWebber's Resource Management Account.


     In order to enroll in the Plan, an investor must have opened an RMA account
with PaineWebber  or  one  of  its  correspondent  firms.  The  RMA  account  is
PaineWebber's  comprehensive  asset management  account  and offers  investors a
number of features, including the following:

   monthly  Premier  account  statements  that  itemize  all  account  activity,
   including  investment transactions, checking  activity and Gold MasterCard'r'
   transactions during the period, and provide unrealized and realized gain  and
   loss estimates for most securities held in the account;

   comprehensive  preliminary  9-month  and  year-end  summary  statements  that
   provide information  on account  activity for  use in  tax planning  and  tax
   return preparation;

   automatic  'sweep' of uninvested cash into  the RMA accountholder's choice of
   one of the five  RMA money market  funds -- RMA  Money Market Portfolio,  RMA
   U.S.  Government Portfolio, RMA Tax-Free Fund, RMA California Municipal Money
   Fund and RMA New York Municipal  Money Fund. Each money market fund  attempts
   to  maintain a  stable price  per share  of $1.00,  although there  can be no
   assurance that it  will be able  to do  so. Investments in  the money  market
   funds are not insured or guaranteed by the U.S. government;

   check  writing, with no  per-check usage charge, no  minimum amount on checks
   and no maximum number of checks  that can be written. RMA accountholders  can
   code  their checks to classify expenditures. All canceled checks are returned
   each month;

   Gold MasterCard,  with  or without  a  line  of credit,  which  provides  RMA
   accountholders  with direct  access to  their accounts  and can  be used with
   automatic teller machines  worldwide. Purchases  on the  Gold MasterCard  are
   debited  to the RMA account once monthly, permitting accountholders to remain
   invested for a longer period of time;

   24-hour access to  account information  through toll-free  numbers, and  more
   detailed  personal  assistance during  business  hours from  the  RMA Service
   Center;

   expanded account protection to $25 million in the event of the liquidation of
   PaineWebber. This protection does not apply to shares of the RMA money market
   funds or the PW Funds because those shares are held at the transfer agent and
   not through PaineWebber; and

   automatic direct  deposit  of checks  into  your RMA  account  and  automatic
   withdrawals from the account.

     The  annual account fee for an RMA  account is $85, which includes the Gold
MasterCard, with an additional  fee of $40 if  the investor selects an  optional
line of credit with the Gold MasterCard.

 

                          CONVERSION OF CLASS B SHARES

     Class  B shares of the  Fund will automatically convert  to Class A shares,
based on the relative net asset values of  each of the Classes, as of the  close
of  business on the first Business Day (as  defined below) of the month in which
the sixth anniversary of the initial issuance of such Class B shares of the Fund
occurs.  For  the  purpose  of  calculating  the  holding  period  required  for
conversion  of Class B shares,  the date of initial  issuance shall mean (1) the
date on  which such  Class B  shares  were issued,  or (2)  for Class  B  shares
obtained  through an exchange, or  a series of exchanges,  the date on which the
original Class B  shares were  issued. For purposes  of conversion  to Class  A,
Class  B  shares  purchased  through the  reinvestment  of  dividends  and other
distributions paid in  respect of  Class B  shares will  be held  in a  separate
sub-account.  Each time any Class B  shares in the shareholder's regular account
(other




 
                                       15
 

<PAGE>
<PAGE>

than those in the  sub-account)  convert  to Class A, a pro rata  portion of the
Class B shares in the sub-account will also convert to Class A. The portion will
be determined by the ratio that the  shareholder's  Class B shares converting to
Class A bears to the  shareholder's  total Class B shares not  acquired  through
dividends and other distributions.

 

     The availability of the conversion feature is subject to (1) the continuing
applicability of a ruling of the Internal Revenue Service that the dividends and
other  distributions  paid on  Class A  and Class  B shares  will not  result in
'preferential  dividends'  under   the  Internal  Revenue   Code  and  (2)   the
continuing  availability  of  an  opinion  of counsel  to  the  effect  that the
conversion of shares  does not  constitute a  taxable event.  If the  conversion
feature  ceased to be  available, the Class B  shares of each  Fund would not be
converted and would continue to be subject to the higher ongoing expenses of the
Class B shares beyond six years from the date of purchase. Mitchell Hutchins has
no reason  to  believe  that  these  conditions  for  the  availability  of  the
conversion feature will not continue to be met.


                              VALUATION OF SHARES

     The Fund determines the net asset value per share separately for each Class
of shares as of the close of regular trading (currently 4:00 p.m., Eastern time)
on the NYSE on each Business Day, which is defined as each Monday through Friday
when  the NYSE is open.  Currently, the NYSE is closed  on the observance of the
following holidays: New Year's Day, Presidents' Day, Good Friday, Memorial  Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

     Securities  that are listed on 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 the Sub-Adviser  as the primary market.  Securities traded in the
OTC market and listed on Nasdaq are  valued at the last available sale price  on
Nasdaq  at 4:00 p.m., Eastern time; other  OTC securities are valued at the last
bid price available prior to valuation.

     Where market quotations, are readily available, debt securities are  valued
based upon those quotations, provided such quotations adequately reflect, in the
Sub-Adviser's judgment, fair value of the security. Where such market quotations
are  not readily  available, such  securities are  valued based  upon appraisals
received from a  pricing service using  a computerized matrix  system, or  based
upon  appraisals  derived from  information concerning  the security  or similar
securities received  from  recognized dealers  in  those securities.  All  other
securities or assets will be valued at fair value as determined in good faith by
or  under the  direction of  the Trust'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 Trust's board of trustees determines that
this does not represent fair value.

                            PERFORMANCE INFORMATION

     The  Fund's performance  data quoted  in advertising  and other promotional
materials ('Performance Advertisements') represent past performance and are  not
intended  to indicate  future performance.  The investment  return and principal
value of  an  investment will  fluctuate  so  that an  investor's  shares,  when
redeemed, may be worth more or less than their original cost.

     TOTAL  RETURN. Average  annual total return  quotes ('Standardized Return')
used in the Fund's  Performance Advertisements are  calculated according to  the
following formula:


<TABLE>
<S>                 <C>
     P(1 + T)'pp'n  =     ERV
where:        P     =     a hypothetical initial payment of $1,000 to purchase shares of a specified Class
              T     =     average annual total return of shares of that Class
              n     =     number of years
              ERV   =     ending redeemable value of a hypothetical $1,000 payment made at the
                          beginning of that period.
</TABLE>

     Under   the  foregoing  formula,  the  time  periods  used  in  Performance
Advertisements will be based on rolling  calendar quarters, updated to the  last
day  of the  most recent  quarter prior to  submission of  the advertisement for
publication. Total return, or 'T' in  the formula above, is computed by  finding
the  average annual change in the value of an initial $1,000 investment over the
period. In  calculating the  ending redeemable  value for  Class A  shares,  the
Fund's  maximum 4.5%  initial sales charge  is deducted from  the initial $1,000
payment and, for Class B and Class C shares, the applicable contingent  deferred
sales  charge imposed on a redemption of Class B and Class C shares held for the
period is deducted. All  dividends and other distributions  are assumed to  have
been reinvested at net asset value.


     The  Fund  also may  refer in  Performance  Advertisements to  total return
performance data that  are not  calculated according  to the  formula set  forth
above  ('Non-Standardized Return'). The  Fund calculates Non-Standardized Return
for specified  periods of  time by  assuming the  investment of  $1,000 in  Fund
shares  and assuming the reinvestment of  all dividends and other distributions.
The rate  of  return is  determined  by subtracting  the  initial value  of  the
investment  from the ending value  and by dividing the  remainder by the initial
value. Neither  initial nor  contingent deferred  sales charges  are taken  into
account  in calculating Non-Standardized Return;  the inclusion of these charges
would reduce the return.

     Both Standardized Return and Non-Standardized Return for Class B shares for
periods of over six years will reflect conversion of the Class B shares to Class
A shares at the end of the sixth year.

     The following table shows performance information for the Class A and Class
C shares  of  the  Fund for  the  periods  indicated. No  Class  B  shares  were
outstanding  during those periods. All returns for periods of more than one year
are expressed as an average return.

 * All Standardized Return figures for Class  A shares reflect deduction of  the
   current  maximum sales charge of 4.5%. Class  C shares impose a 1% contingent
   deferred sales charge  only on redemptions  made within a  year of  purchase;
   therefore,  for  periods longer  than  one year,  Non-Standardized  Return is
   identical to Standardized Return.

** The inception date for the Class A shares  is May 10, 1993 and July 22,  1992

     OTHER  INFORMATION. In Performance Advertisements, the Fund may compare its
Standardized Return and/or  its Non-Standardized Return  with data published  by

published by the U.S. Department  of Commerce. The Fund  also may refer in  such
materials   to  mutual  fund  performance  rankings  and  other  data,  such  as
comparative  asset,  expense   and  fee  levels,   published  by  Lipper,   CDA,
Wiesenberger,  ICD or Morningstar. Performance  Advertisements also may refer to
discussions of the Fund and comparative mutual fund data and ratings reported in
independent periodicals, including (but not limited to) THE WALL STREET JOURNAL,
MONEY Magazine, FORBES, BUSINESS WEEK,  FINANCIAL WORLD, BARRON'S, FORTUNE,  THE
NEW  YORK  TIMES, THE  CHICAGO TRIBUNE,  THE WASHINGTON  POST and  THE KIPPINGER
LETTERS. Comparisons in Performance Advertisements may be in graphic form.

     The Fund  may  include  discussions  or illustrations  of  the  effects  of
compounding  in  Performance Advertisements.  'Compounding'  refers to  the fact
that, if dividends or other distributions on a Fund investment are reinvested by
being paid in additional Fund shares, any future income or capital  appreciation
of  the Fund would increase the value, not only of the original Fund investment,
but also  of the  additional Fund  shares received  through reinvestment.  As  a
result,  the value of  the Fund investment  would increase more  quickly than if
dividends or other distributions had been paid in cash.

     The Fund may  also compare  its performance  with the  performance of  bank
certificates  of deposits (CDs) as measured  by the CDA Investment Technologies,
Inc. Certificate of Deposit Index, the Bank Rate Monitor National Index and  the
averages  of  yields  of CDs  of  major  banks published  by  Banxquote'r' Money
Markets. In comparing the Fund's performance to CD performance, investors should
keep in mind that bank CDs are insured in  whole or in part by an agency of  the
U.S.  government  and  offer fixed  principal  and  fixed or  variable  rates of
interest,  and  that  bank  CD  yields  may  vary  depending  on  the  financial
institution  offering the CD and prevailing  interest rates. Fund shares are not
insured or guaranteed by the U.S.  government and returns thereon and net  asset
value will fluctuate. The debt securities held by the Fund generally have longer
maturities  than most CDs and may  reflect interest rate fluctuations for longer
term securities.  An investment  in  the Fund  involves  greater risks  than  an
investment in either a money market fund or a CD.

                                     TAXES

     Set forth below is a summary of certain income tax considerations generally
affecting  the  Fund and  its shareholders.  The  summary is  not intended  as a
substitute for individual tax  planning, and shareholders  are urged to  consult
their  tax  advisors  regarding the  application  of federal,  state,  local and
foreign tax laws to their specific tax situations.
 
TAX STATUS OF THE FUND AND ITS SHAREHOLDERS
 
     The Fund  will be  treated as  a  separate entity  for federal  income  tax
purposes. The Fund's net investment income, capital gains and distributions will
be determined separately from any other series that the Trust may designate.

     The  Fund has  qualified for the  fiscal year  ended August 31,  1995 to be
treated as a 'regulated investment company'  under the Internal Revenue Code  of
1986,  as  amended (the  'Code') and  intends  to continue  to qualify  for this
treatment for each year. If the Fund  (1) is a regulated investment company  and
(2)  distributes to its shareholders  at least 90% of  its net investment income
(including for this purpose its net realized short-term capital gains), the Fund
will not  be  liable  for federal  income  taxes  to the  extent  that  its  net
investment  income and its net realized  long-term and short-term capital gains,
if any, are distributed to its shareholders.

 
     The Fund's transactions  in options  and futures contracts  are subject  to
special  provisions  of  the  Code  that, among  other  things,  may  affect the
character of gains and losses realized by the Fund (that is, may affect  whether
gains  or losses are  ordinary or capital), accelerate  recognition of income to
the Fund and  defer Fund  losses. These rules  (1) could  affect the  character,
amount and timing of distributions to shareholders of the Fund, (2) will require
the  Fund to 'mark  to market' certain  types of the  positions in its portfolio
(that is, treat them as if they were closed out), and (3) may cause the Fund  to
recognize  income without  receiving cash  with which  to make  distributions in
amounts necessary to satisfy the  distribution requirements for avoiding  income
and  excise  taxes described  above and  in  the Prospectus.  The Fund  seeks to
monitor its transactions, seeks to make the appropriate tax elections and  seeks
to  make the appropriate entries  in its books and  records when it acquires any
futures contract or hedged investment, to mitigate the effect of these rules and
prevent disqualification of the Fund as a regulated investment company.
 
     If the Fund is the holder of record of any stock on the record date for any
dividends payable with respect to such stock, such dividends are included in the
Fund's gross  income  as  of  the  later of  (1)  the  date  such  stock  became
ex-dividend  with respect to such dividends (i.e.,  the date on which a buyer of
the stock would not be entitled to receive the declared, but unpaid,  dividends)
or  (2) the date the Fund acquired  such stock. Accordingly, in order to satisfy
its income distribution requirements, the Fund may be required to pay  dividends
based  on anticipated  earnings, and  shareholders may  receive dividends  in an
earlier year than would otherwise be the case.
 
     As a general rule, a shareholder's gain or loss on a sale or redemption  of
Fund  shares is a long-term capital gain or loss if the shareholder has held the
shares for more than one year. The gain or loss is a short-term capital gain  or
loss if the shareholder has held the shares for one year or less.
 
     The  Fund's  net  realized  long-term  capital  gains  are  distributed  as
described in the  Prospectus. The distributions  ('capital gain dividends'),  if
any,  are taxable to shareholders as  long-term capital gains, regardless of how
long a shareholder  has held  Fund shares, and  are designated  as capital  gain
dividends


 
                                       19
 

<PAGE>
<PAGE>

in a written  notice mailed by the Trust to the  shareholders  of the Fund after
the close of the Fund's prior taxable year. If a shareholder  receives a capital
gain dividend with respect to any Fund share, and if the share is sold before it
has been held by the shareholder for more than six months,  then any loss on the
sale or exchange of the share,  to the extent of the capital gain  dividend,  is
treated as a long-term capital loss.
 
     Investors considering buying  Fund shares on  or just prior  to the  record
date  for a taxable dividend  or capital gain distribution  should be aware that
the amount of the forthcoming dividend or distribution payment will be a taxable
dividend or distribution payment.
 

     Special  rules  contained  in the Code  apply when a Fund  shareholder  (1)
disposes of shares of the Fund through a redemption  or exchange  within 90 days
of purchase and (2) subsequently acquires shares of a PaineWebber mutual fund on
which a sales  charge  normally  is  imposed  without  paying a sales  charge in
accordance with the exchange  privilege  described in the  Prospectus.  In these
cases,  any gain on the  disposition  of the Fund shares is  increased,  or loss
decreased, by the amount of the sales charge paid when the shares were acquired,
and that amount will increase the adjusted basis of the fund shares subsequently
acquired.  In addition,  if shares of the Fund are  purchased  within 30 days of
redeeming shares at a loss, the loss is not deductible and instead increases the
basis of the newly purchased shares.

 
     If  a  shareholder  fails to  furnish  the  Trust with  a  correct taxpayer
identification number, fails  to report  fully dividend or  interest income,  or
fails  to certify that he or she  has provided a correct taxpayer identification
number and that  he or  she is  not subject  to 'backup  withholding,' then  the
shareholder  may be subject to 31% 'backup  withholding' tax with respect to (1)
taxable dividends and distributions  from the Fund and  (2) the proceeds of  any
redemptions  of Fund shares.  An individual's taxpayer  identification number is
his or  her  social  security number.  The  backup  withholding tax  is  not  an
additional  tax and may be credited  against a taxpayer's regular federal income
tax liability.
 
                               OTHER INFORMATION

     The Trust  was  organized  as  a  business trust  under  the  laws  of  The
Commonwealth of Massachusetts pursuant to a Declaration of Trust dated March 28,
1991,  as  amended from  time to  time (the  'Declaration'). The  Fund commenced
operations on July 22, 1992. Prior to November 1, 1995, the name of the Fund was
'Mitchell Hutchins/Kidder, Peabody Asset Allocation Fund.' Prior to February 13,
1995, the name of the Fund was 'Kidder, Peabody Asset Allocation Fund.' Prior to
November 10, 1995, the Fund's Class C  shares were called 'Class B' shares.  New
Class B shares were not offered prior to January 1, 1996.


     Massachusetts  law  provides that  shareholders of  the Trust  could, under
certain circumstances,  be held  personally liable  for the  obligations of  the
Trust.  The Declaration disclaims shareholder  liability for acts or obligations
of the Trust, however, and  requires that notice of  the disclaimer be given  in
each  agreement, obligation or instrument entered  into or executed by the Trust
or a  Trustee. The  Declaration provides  for indemnification  from the  Trust's
property  for  all losses  and expenses  of  any shareholder  of the  Trust held
personally liable for the  obligations of the  Trust. Thus, the  risk of a  Fund
shareholder  incurring  financial loss  on account  of shareholder  liability is
limited to  circumstances  in  which the  Trust  would  be unable  to  meet  its
obligations,  a possibility that the Trust's management believes is remote. Upon
payment of  any liability  incurred by  the Trust,  the shareholder  paying  the
liability  will  be entitled  to reimbursement  from the  general assets  of the
Trust. The Trustees intend to


 
                                       20
 

<PAGE>
<PAGE>

conduct  the  operations  of the Trust in such a way so as to  avoid,  as far as
possible, ultimate liability of the shareholders for liabilities of the Trust.


     CLASS-SPECIFIC  EXPENSES.  The Fund might determine to allocate  certain of
its expenses (in addition to distribution  fees) to the specific  Classes of the
Fund's shares to which those  expenses are  attributable.  For example,  Class B
shares of the Funds bear higher  transfer  agency fees per  shareholder  account
than those borne by Class A or Class C shares.  The higher fee is imposed due to
the higher costs incurred by the Transfer Agent in tracking  shares subject to a
contingent deferred sales charge because,  upon redemption,  the duration of the
shareholder's investment must be determined in order to determine the applicable
charge.  Moreover,  the  tracking  and  calculations  required by the  automatic
conversion  feature of the Class B shares will cause the Transfer Agent to incur
additional costs.  Although the transfer agency fee will differ on a per account
basis as stated  above,  the specific  extent to which the transfer  agency fees
will differ  between the Classes as a  percentage  of net assets is not certain,
because the fee as a percentage  of net assets will be affected by the number of
shareholder  accounts  in each Class and the  relative  amounts of net assets in
each Class.

PAINEWEBBER   TACTICAL ALLOCATION FUND

                               PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
     See  the body of the Prospectus for more information on topics discussed in
this summary.
 
WHO SHOULD INVEST. The Fund follows a systematic investment strategy that
actively allocates the Fund's assets among common stocks, U.S. Treasury Notes
and U.S. Treasury Bills and is designed for investors who are seeking total
return, consisting of long-term capital appreciation and current income. The
Fund's risk factors are summarized below and are described in more detail under
'Investment Objective and Policies -- Risk Factors and Special Considerations.'
While the Fund is not intended to provide a complete or balanced investment
program, it can serve as one component of an investor's long-term program to
accumulate assets, for instance, for retirement, college tuition or other major
goals.


ASSET ALLOCATION STRATEGY. The Fund follows an asset allocation strategy
involving investing among the following asset categories ('Segments'): (1) the
common stocks primarily included in the Standard & Poor's 500 Composite Stock
Price Index (the 'S&P 500 Index') and derivative instruments relating thereto
(the 'Stock Segment'), the performance of which, before deduction of operating
expenses, is intended to replicate as closely as possible the aggregate price
and yield performance of the S&P 500 Index; (2) 30-day U.S. Treasury Bills (the
'Cash Segment'); and (3) five-year U.S. Treasury Notes and derivative
instruments relating thereto (the 'Note Segment'). Asset allocations are
determined by Mitchell Hutchins based on relative rates of return among the
Segments. See 'Investment Objective and Policies.' The Fund's asset allocation
strategy is designed to afford investors the opportunity to seek total return
during all economic and financial market cycles, with a degree of volatility
lower than that of the equity market, utilizing a systematic, cost effective
asset allocation strategy. The Fund allocates its assets among the Segments in
accordance with an Asset Allocation Model (the 'Allocation Model') utilized by
Mitchell Hutchins. See 'Investment Objective and Policies -- Asset Allocation
Strategy.'

 
RISK FACTORS. There can be no assurance that the Fund will achieve its
investment objective, and the Fund's net asset value will fluctuate based upon
changes in the value of its portfolio securities.
 
Although the Fund will seek long term total return consisting of both capital
appreciation and current income, the Fund may not achieve as high a level of
either capital appreciation or current income as a fund that has only one of
those objectives as its primary objective. Because the benefits of the
Allocation Model, on which the Fund's investment decisions are based, are
expected to be realized only if the recommendations are followed over several
market cycles, the Fund is intended to be a long term investment vehicle and is
not designed to provide investors with a means of speculating on short term
market movements. The investment results of the Fund (and the Stock Segment) at
any time may be greater or less than those of the S&P 500 Index. Deviations from
the performance of the S&P 500 Index may result from the proportion of assets
then allocated to the Stock Segment in accordance with the Allocation Model,
purchases and redemptions of shares of the Fund that occur daily, as well as
from brokerage and other expenses borne by the Fund. Thus, no assurance can be
given that the Fund's investment objective will be achieved. The Fund may also
be subject to certain risks in using investment techniques and strategies such
as entering into futures contracts and options on futures contracts, entering
into transactions involving options on stock indexes, purchasing securities on a
when-issued or delayed delivery basis and entering into repurchase agreements.
See 'Investment Objective and Policies -- Risk Factors and Special
Considerations' at page 10 of this Prospectus.

                       EXAMPLE OF EFFECT OF FUND EXPENSES
 
An investor would directly or indirectly pay the following expenses on a $1,000
investment in the Fund, assuming a 5% annual return:
 
<TABLE>
<CAPTION>
ONE YEAR      THREE YEARS      FIVE YEARS      TEN YEARS
- --------      -----------      ----------      ---------
<S>           <C>              <C>             <C>
  $ 28            $85             $144           $ 306
</TABLE>
 
This Example assumes that all dividends and other distributions are reinvested
and that the percentage amounts listed under Annual Fund Operating Expenses
remain the same in the years shown. The above tables and the assumption in the
Example of a 5% annual return are required by regulations of the Securities and
Exchange Commission ('SEC') applicable to all mutual funds; the assumed 5%
annual return is not a prediction of, and does not represent, the projected or
actual performance of Class Y shares of the Fund.
 
THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES, AND THE FUND'S ACTUAL EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN.
The actual expenses attributable to Class Y shares of the Fund will depend upon,
among other things, the level of average net assets and the extent to which the
Fund incurs variable expenses, such as transfer agency costs.

PAINEWEBBER   TACTICAL ALLOCATION FUND

                       INVESTMENT OBJECTIVE AND POLICIES

- --------------------------------------------------------------------------------
 
OBJECTIVE
 
The Fund's investment objective is long-term capital appreciation. The Fund
seeks to achieve its objective by investing primarily in equity securities of
small capitalization companies.
 
There can be no assurance that the Fund will achieve its investment objective.
The Fund's net asset value will fluctuate based upon changes in the value of its
portfolio securities. The Fund's investment objective and certain investment
limitations, as described in the Statement of Additional Information, are
fundamental policies and may not be changed without shareholder approval. All
other investment policies may be changed by the Trust's board of trustees
without shareholder approval.
 
ASSET ALLOCATION STRATEGY
 
The Fund is designed for investors seeking total return during all economic and
financial market cycles, with a degree of volatility lower than that of the
equity market, utilizing a systematic, cost-effective approach to allocating
assets among market segments. At the same time, the Fund provides individual
investors a means of dealing with the difficulties often associated with asset
allocation investing with an index component.
 
In seeking total return, the Fund follows an asset allocation strategy
contemplating shifts (sometimes frequent) among the following Segments: (i) the
Stock Segment, consisting primarily of the common stocks included in the S&P 500
Index and derivative instruments relating thereto, the performance of which,
before deduction of operating expenses, is intended to replicate as closely as
possible that of the S&P 500 Index; (ii) the Cash Segment, consisting of 30-day
U.S. Treasury Bills; and (iii) the Note Segment, consisting of five-year U.S.
Treasury Notes and derivative instruments relating thereto.
 

The Fund allocates its assets among the Segments in accordance with the
Allocation Model. The emphasis of the Allocation Model is to avoid or lower
exposure to the market in down economic cycles and to perform close to the broad
market in periods of strongly positive market performance. The asset allocation
mix for the Fund will be determined by Mitchell Hutchins at any given time on
the basis of the recommendations of the Allocation Model, except as described
below, which are determined in light of a quantitative assessment of the
expected performance of the Segments. The Fund is not managed as a balanced
portfolio, however, and may not maintain a portion of its investments in each of
the Segments at all times. Except for limited amounts always held in the Cash
Segment as described below, the Fund does not commit its assets simultaneously
to the Cash Segment and the Note Segment. Thus, during the course of a business
cycle, for example, the Fund may invest in the Stock Segment and the Cash
Segment, in the Stock Segment and the Note Segment, solely in the Stock Segment,
solely in the Cash Segment or solely in the Note Segment.

 
The Fund's assets are reallocated among the Segments at such times as are
mandated by the Allocation Model based on changes in projected rates of return.
If no reallocation is mandated, on the first business day of each month, any
material amounts in each Segment in excess of the amount mandated by the
Allocation Model resulting from appreciation or receipt of dividends,
distributions, interest payments and proceeds from securities maturing are
reallocated (or 'rebalanced') to the extent practicable among the Segments so as
to reestablish the recommended allocation among the Segments.
 
Cash inflows to the Fund during a month are invested in, and cash outflows from
the Fund during a month are derived from dispositions of assets in, each Segment
on a pro rata basis. In order to manage the Fund's portfolio most effectively,
cash flows into and out of the Stock Segment are managed to the extent
practicable through the use of stock index options, stock index futures
contracts and options on stock index futures contracts, as described below.
Similarly, cash flows into and out of the Note Segment are managed to the extent
practicable through the use of five-year U.S. Treasury Note

futures contracts and options thereon. See 'Investment Strategies and
Techniques -- Derivative Instruments' below.
 
The Fund deviates from the published recommendations of the Allocation Model
only to the extent necessary (1) to maintain a limited amount of assets (not
expected to exceed 2% of its total assets) in the Cash Segment in order to have
highly liquid short-term securities available to pay Fund operating expenses and
dividends and distributions on its shares and to meet anticipated redemptions of
its shares and (2) to qualify as a regulated investment company for Federal
income tax purposes. With regard to the latter, investors should be aware that
in order to so qualify, the Fund must, among other things, derive less than 30%
of its gross income from the sale or disposition of stocks, other securities and
certain financial instruments held for less than three months. Thus, this
requirement may preclude the Fund from reallocating its assets when otherwise
mandated by the Allocation Model. In such event, the Fund would reallocate its
assets in accordance with the then current recommendations of the Allocation
Model as soon as the reallocation could be accomplished without jeopardizing the
Fund's qualification as a regulated investment company.
 
TYPES OF PORTFOLIO INVESTMENTS
 
CASH SEGMENT.  Assets committed to the Cash Segment are invested to the extent
practicable in U.S. Treasury Bills having remaining maturities of 30 days or, if
no such instruments are then available for purchase at favorable prices, these
assets will be invested in U.S. Treasury Bills having remaining maturities as
close as possible to 30 days. U.S. Treasury Bills are entitled to the full faith
and credit of the U.S. Government as to payment of interest and principal.
 
NOTE SEGMENT.  Assets committed to the Note Segment are invested to the extent
practicable in (1) U.S. Treasury Notes having five years remaining to maturity
at the beginning of the then current calendar year or, if no such instruments
are then available for purchase at favorable prices, these assets will be
invested in U.S. Treasury Notes having remaining maturities as close as possible
to five years at the beginning of the then current calendar year; and (2)
five-year U.S. Treasury Note futures contracts and options thereon. U.S.
Treasury Notes are entitled to the full faith and credit of the U.S. Government
as to payment of interest and principal.

STOCK SEGMENT.  With respect to assets committed to the Stock Segment, the Fund
attempts to duplicate, before deduction of operating expenses, the investment
results of the S&P 500 Index. The S&P 500 Index is an index compiled by Standard
& Poor's Corporation ('S&P') that emphasizes large-capitalization companies. The
Stock Segment is not managed according to traditional methods of 'active'
investment management, which involve the buying and selling of securities based
on economic, financial and market analysis and investment judgment. Instead,
utilizing a 'passive' or 'indexing' investment approach, the Fund attempts in
the Stock Segment to duplicate the investment performance of the S&P 500 Index
through statistical procedures that involve holding substantially all 500 stocks
in approximately the same relative proportions as they are represented in the
S&P 500 Index, except as described below.
 
The S&P 500 Index is composed of 500 common stocks that are chosen by S&P on a
statistical basis. The composition of the S&P 500 Index is determined by S&P
based on such factors as the market capitalization and trading activity of each
stock and its adequacy as a representative of stocks in a particular industry
group, and may be changed from time to time. Each stock in the S&P 500 Index is
weighted by its market capitalization, which is the market price per share of
the stock multiplied by the number of shares outstanding. While most of the
stocks in the S&P 500 Index are issued by companies that are among the 500
largest companies in terms of market capitalization, some stocks are included
for diversification and are not among the 500 largest market capitalization
stocks. The inclusion of a stock in the S&P 500 Index in no way implies that S&P
believes the stock to be an attractive investment.
 
While there can be no guarantee that the Stock Segment's investment results will
precisely match those of the S&P 500 Index, Mitchell Hutchins believes that,
before deduction of operating expenses, there will be a very high correlation
between the returns generated by the Stock Segment and the S&P 500 Index. The
Fund attempts to achieve a correlation between the performance of the Stock
Segment and that of its benchmark index of at least 0.95, before deduction of
operating expenses. A correlation of 1.00 would indicate perfect correlation,
which

would be achieved when the Stock Segment's net asset value, including the value
of its dividend and capital gains distributions, increases or decreases in exact
proportion to changes in the S&P 500 Index. The Fund's ability to correlate the
performance of the Stock Segment with the S&P 500 Index may be affected by,
among other things, changes in securities markets, the manner in which the S&P
500 Index is calculated by S&P and the timing of purchases and redemptions. See
'Risk Factors and Special Considerations -- Index Investing and Open-End
Investment Companies' below. Mitchell Hutchins monitors the correlation of the
performance of the Stock Segment in relation to that of the S&P 500 Index under
the supervision of the Board of Trustees. In the unlikely event that a high
correlation is not achieved, the Board of Trustees will take appropriate steps
based on the reasons for the lower than expected correlation. S&P is neither a
sponsor of nor affiliated with the Fund.
 
INVESTMENT TECHNIQUES AND STRATEGIES
 
The Fund is authorized to engage in any one or more of the specialized
investment techniques and strategies described below:
 
DERIVATIVE INSTRUMENTS.  The Fund anticipates that the Note Segment and the
Stock Segment will remain invested in five-year U.S. Treasury Notes or common
stocks, respectively, to the degree mandated by the Allocation Model. The Fund
may also invest its assets in stock index options, stock index futures contracts
and options on stock index futures contracts (with respect to the Stock Segment)
and five-year U.S. Treasury Note futures contracts and options thereon (with
respect to the Note Segment) in order to invest temporarily uncommitted cash
balances, to maintain liquidity to meet shareholder redemptions or, in the case
of stock index options, to minimize trading costs. When the Fund has cash from
net new sales of Fund shares or holds a disproportionate amount of its assets in
the Cash Segment, it may enter into stock index futures or options thereon or
five-year U.S. Treasury Note futures contracts or options thereon to attempt to
increase its exposure to the appropriate asset class prior to purchasing
securities to the degree mandated by the Allocation Model. Strategies the Fund
could use to accomplish this include entering into long futures contracts,
writing put options and purchasing call options. When the Fund wishes to sell
securities, because of shareholder redemptions or otherwise, it may use futures
contracts or options to hedge against market risk until the sale can be
completed. These strategies could include entering into short futures contracts,
writing call options and purchasing put options. It is anticipated that the Fund
will continue to close out positions in these instruments on at least a
quarterly basis and reconstitute its portfolio with direct purchases or sales of
securities in accordance with the then current recommendations of the Allocation
Model. The Fund does not enter into futures contracts or options as part of a
temporary defensive strategy, such as lowering the Stock Segment's investment in
common stocks to protect against potential stock market declines, as this would
be inconsistent with the Allocation Model. See 'Stock Index Options' and
'Futures Contracts and Options on Futures Contracts' below.
 
STOCK INDEX OPTIONS.  The Fund may purchase and write put and call options on
stock indexes listed on domestic securities exchanges (which indexes include
securities held in the Fund's portfolio) as a means of pursuing the Stock
Segment's exposure in equity markets without making direct purchases of equity
securities.
 
A stock index measures the movement of a certain group of stocks by assigning
relative values to the common stocks included in the index. Options on stock
indexes are generally similar to options on specific securities. Unlike those on
securities, however, options on stock indexes do not involve the delivery of an
underlying security; the option in the case of an option on a stock index
represents the holder's right to obtain from the writer in cash a fixed multiple
of the amount by which the exercise price exceeds (in the case of a put) or is
less than (in the case of a call) the closing value of the underlying stock
index on the exercise date.
 
When the Fund writes an option on a stock index, it establishes a segregated
account with its custodian in which the Fund deposits cash or cash equivalents
or a combination of both in an amount equal to the market value of the option
and maintains the account while the option is open. If the Fund has written a
stock index option, it may terminate its obligation by effecting a closing
purchase transaction, which is accomplished by purchasing an option of the same
series as the option previously written.

PAINEWEBBER   TACTICAL ALLOCATION FUND

 

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.  The Fund may enter into
stock index futures contracts, and options on those contracts, as a means of
temporarily increasing or decreasing the Stock Segment's exposure to equity
markets in anticipation of purchases or sales of common stocks. Similarly, the
Fund may enter into five-year U.S. Treasury Note futures contracts, and options
on those contracts, as a means of temporarily increasing or decreasing the Note
Segment's exposure to five-year U.S. Treasury Notes in anticipation of purchase
or sales of these notes. A futures contract is an agreement to take or make
delivery of an amount of cash equal to the difference between the value of the
index or security at the beginning and at the end of the contract period. An
option on a futures contract, in contrast to a direct investment in the
contract, gives the purchaser the right, in return for the premium paid, to
assume a position in the underlying futures contract at a specified exercise
price at any time on or before the expiration date of the option.
 
The Fund may assume both 'long' and 'short' positions with respect to futures
contracts. A long position involves entering into a futures contract to buy a
commodity, whereas a short position involves entering into a futures contract to
sell a commodity. In entering into futures contracts, the Fund is required to
make initial 'margin' payments, which are payments in the nature of performance
bonds or good faith deposits, and to make 'variation' margin payments from time
to time as the values of the futures contracts fluctuate.
 
The Fund does not (1) enter into any futures contracts or options on futures
contracts if, immediately after the transactions, the aggregate of margin
deposits on all of the Fund's outstanding futures contracts and premiums paid on
its outstanding options on futures contracts would exceed 5% of the market value
of the total assets of the Fund after taking into account unrealized profits and
losses on any futures contracts or options on futures contracts or (2) enter
into any futures contracts or options on futures contracts if the aggregate of
the market value of the Fund's outstanding futures contracts and market value of
the currencies and futures contracts subject to outstanding options written by
the Fund would exceed 50% of the market value of the total assets of the Fund.
Each short position in a futures or options contract entered into by the Fund is
secured by the Fund's ownership of underlying securities. The Fund does not use
leverage when it enters into long futures or options contracts; the Fund places
in a segregated account with its custodian, or designated sub-custodian, with
respect to each of its long positions cash or short-term U.S. Treasury Bills
having a value equal to the underlying commodity value of the contract.
 
REPURCHASE AGREEMENTS.  In order to manage cash flows resulting from the
continuous sale and redemption of the Fund's shares, the Fund may engage in
repurchase agreement transactions collateralized by U.S. Treasury obligations.
Although the amount of the Fund's assets that may be invested in repurchase
agreements terminable in less than seven days is not limited, repurchase
agreements maturing in more than seven days, together with other illiquid
securities, may not exceed 10% of the Fund's net assets. The Fund may engage in
repurchase agreement transactions with certain member banks of the Federal
Reserve System and with certain dealers listed on the Federal Reserve Bank of
New York's list of reporting dealers. Under the terms of a typical repurchase
agreement, the Fund would acquire an underlying debt obligation for a relatively
short period (usually not more than seven days) subject to an obligation of the
seller to repurchase, and the Fund to resell, the obligation at an agreed-upon
price and time, thereby determining the yield during the Fund's holding period.
This arrangement results in a fixed rate of return that is not subject to market
fluctuations during the Fund's holding period. The value of the securities
underlying a repurchase agreement of the Fund is monitored on an ongoing basis
by Mitchell Hutchins to ensure that the value is at least equal at all times to
the total amount of the repurchase obligation, including interest. Mitchell
Hutchins also monitors, on an ongoing basis to evaluate potential risks, the
creditworthiness of those banks and dealers with which the Fund enters into
repurchase agreements.
 
WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES.  To secure prices or yields deemed
advantageous at a particular time, the Fund may purchase securities on a
when-issued or delayed-delivery basis, in which case delivery of the securities
occurs beyond the normal settlement period; payment for or delivery of the
securities would be made prior to the reciprocal delivery or payment by the
other party to the transaction. The Fund enters into when-issued or
delayed-delivery trans-

actions for the purpose of acquiring securities and not for the purpose of
leverage. When-issued securities purchased by the Fund may include securities
purchased on a 'when, as and if issued' basis under which the issuance of the
securities depends on the occurrence of a subsequent event, such as approval of
a merger, corporate reorganization or debt restructuring. The Fund will
establish with its custodian, or with a designated sub-custodian, a segregated
account consisting of cash, securities issued or guaranteed by the U.S.
Government, its agencies, authorities or instrumentalities ('Government
Securities') or other liquid high-grade debt obligations in an amount equal to
the amount of its when-issued or delayed-delivery purchase commitments.
 
RISK FACTORS AND SPECIAL CONSIDERATIONS
 
Investing in the Fund involves risks and special considerations, such as those
described below:
 
LIMITS OF ASSET ALLOCATION STRATEGY.  Although it seeks total return, consisting
of both capital appreciation and current income, in following its asset
allocation strategy, the Fund may not achieve as high a level of either capital
appreciation or current income as a fund that has only one of those objectives
as its primary objective. In addition, qualification as a regulated investment
company for federal income tax purposes may limit the Fund's ability to adhere
rigidly to the recommendations of the Allocation Model. See 'Asset Allocation
Strategy' above.
 
INVESTMENT IN COMMON STOCKS.  Although the Allocation Model is designed to
reduce the volatility inherent in a common stock portfolio, to the extent the
Fund's assets are committed to the Stock Segement, the share price of the Fund
can be expected to be volatile and investors should be able to tolerate sudden,
sometimes substantial fluctuations in the value of their investment. Because of
the risks associated with common stock investments, the Fund is intended to be a
long term investment vehicle and is not designed to provide investors with a
means of speculating on short-term stock market movements.
 
INDEX INVESTING AND OPEN-END INVESTMENT COMPANIES.  While the Fund through the
Stock Segment attempts to replicate, before deduction of operating expenses, the
investment results of the S&P 500 Index, the investment results of the Stock
Segment generally are not identical to those of the designated index. Deviations
from the performance of the S&P 500 Index may result from shareholder purchases
and redemptions of shares of the Fund that occur daily, as well as from the
expenses borne by the Fund. Shareholder purchases and redemptions result in
daily net cash inflows to or outflows from the Fund. To the extent that a cash
reserve is held to meet expected redemptions or pending investment in portfolio
securities, to the extent that portfolio securities must be sold to meet
redemption requests (with resulting brokerage costs), and to the extent that
purchases and sales of portfolio securities are made to conform the Stock
Segment's holdings more closely to the relative weightings of stocks in the S&P
500 Index in response to cash inflows or outflows and associated brokerage costs
are incurred, these daily inflows or outflows of cash may increase the deviation
between the Stock Segment's investment results and the price and yield
performance of the S&P 500 Index.
 
INVESTMENT IN FOREIGN SECURITIES.  Since the S&P 500 Index includes common
stocks of foreign issuers, to the extent that Fund assets are committed to the
Stock Segment, the Fund is subject to considerations and potential risks not
typically associated with investing in securities issued exclusively by domestic
corporations. The values of foreign investments are affected by changes in
currency exchange rates or exchange control regulations, restrictions or
prohibitions on the repatriation of foreign currencies, application of foreign
tax laws, including withholding taxes, changes in governmental administration or
economic or monetary policy (in the United States or abroad) or changed
circumstances in dealings between nations. Investments in foreign companies
could be affected by other factors not present in the United States, including
expropriation, confiscatory taxation, lack of uniform accounting and auditing
standards and potential difficulties in enforcing contractual obligations.
 
STOCK INDEX OPTIONS.  Stock index options are subject to position and exercise
limits and other regulations imposed by the exchange on which they are traded.
If the Fund writes a stock index option, it may terminate its obligation by
effecting a closing purchase transaction, which is accomplished by purchasing an
option of the same series as the option previously written. The ability of the
Fund to engage in closing purchase transactions with respect to stock index
options depends on the existence of a liquid secondary

PAINEWEBBER   TACTICAL ALLOCATION FUND

 
market. Although the Fund generally purchases or writes stock index options only
if a liquid secondary market for the options purchased or sold appears to exist,
no such secondary market may exist, or the market may cease to exist at some
future date, for some options. No assurance can be given that a closing purchase
transaction can be effected when the Fund desires to engage in such a
transaction.
 
FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. In entering into
transactions involving futures contracts and options on those contracts, the
Fund is subject to a number of risks and special considerations. The successful
use of futures contracts and options on those contracts draws upon Mitchell
Hutchins' special skills and experience with respect to those instruments.
Should markets move in an unexpected manner, the Fund may not achieve the
anticipated benefits of futures contracts or options on those contracts and thus
be in a less advantageous position than if those strategies had not been used.
For a number of reasons, the price of futures may not correlate perfectly with
the movement in the underlying index or security owing to certain market
distortions. First, all participants in the futures market are subject to margin
deposit and maintenance requirements. Rather than meeting additional margin
deposit requirements, investors may close futures contracts through offsetting
transactions that would distort the normal relationship between the underlying
index or security and the futures markets. Second, from the point of view of
speculators, the deposit requirements in the futures market are less onerous
than margin requirements in the securities market. Therefore, increased
participation by speculators in the futures market also may cause temporary
price distortions. Owing to the possibility of price distortions in the futures
market and because of the imperfect correlation between movements in the
underlying index or security and movements in the price of futures contracts,
even a correct forecast of general market trends may not result in a successful
hedging transaction.
 
Certain futures contracts and options on futures contracts are subject to no
daily price fluctuation limits so that adverse market movements could continue
with respect to those instruments to an unlimited extent over a period of time.
 
The Fund's ability to dispose of its positions in futures contracts and options
on those contracts depends on the availability of active markets in those
instruments. Markets in options and futures with respect to a number of
securities are relatively new and still developing. Mitchell Hutchins cannot now
predict the amount of trading interest that may exist in the future in various
types of futures contracts and options. Futures and options may be closed out
only on the exchange on which the contract was entered (or a linked exchange) so
that no assurance can be given that the Fund will be able to utilize these
instruments effectively for the purposes described above. In addition, although
the Fund anticipates that its options and futures transactions does not prevent
the Fund from qualifying as a regulated investment company for federal income
tax purposes, the Fund's ability to engage in options and futures transactions
may be limited by this tax consideration. See 'Dividends, Distributions and
Taxes -- Taxes.' In writing options, the Fund is subject to the risk of loss
resulting from the difference between the premium received for the option and
the price of the futures contract underlying the option that the Fund must
purchase or deliver upon exercise of the option.
 
REPURCHASE AGREEMENTS.  In entering into a repurchase agreement, the Fund bears
a risk of loss in the event that the other party to the transaction defaults on
its obligations and the Fund is delayed or prevented from exercising its rights
to dispose of the underlying securities, including the risk of a possible
decline in the value of the underlying securities during the period in which the
Fund seeks to assert its rights to them, the risk of incurring expenses
associated with asserting those rights and the risk of losing all or a part of
the income from the agreement.
 
WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES. Securities purchased on a
when-issued or delayed-delivery basis may expose the Fund to risk because the
securities may experience fluctuations in value prior to their actual delivery.
The Fund does not accrue income with respect to a when-issued or
delayed-delivery security prior to its stated delivery date. Purchasing
securities on a when-issued or delayed-delivery basis can involve the additional
risk that the yield available in the market when the delivery takes place may be
higher than that obtained in the transaction itself. Purchases of securities on
a when-issued basis when the Fund is substantially fully invested may result in
increased fluctuations in the Fund's net asset value per share.

PAINEWEBBER   TACTICAL ALLOCATION FUND

 PORTFOLIO TRANSACTIONS AND TURNOVER
 
The Board of Trustees of the Trust has determined that, to the extent consistent
with applicable provisions of the 1940 Act and rules and exemptions thereunder,
transactions for the Fund may be executed through PaineWebber if, in the
judgment of Mitchell Hutchins, the use of PaineWebber is likely to result in
price and execution at least as favorable to the Fund as those obtainable
through other qualified broker-dealers, and if, in the transaction, PaineWebber
charges the Fund a fair and reasonable rate consistent with that charged to
comparable unaffiliated customers in similar transactions.
 
The Fund retains the right to sell securities in accordance with recommendations
generated by the Allocation Model irrespective of how long they have been held.
For the fiscal years ended August 31, 1995 and August 31, 1994, the Fund's
portfolio turnover rates were 53.02% and 4.17%, respectively. An annual turnover
rate of 100% would occur if all of the securities held by the Fund are replaced
once during a period of one year. Higher portfolio turnover rates can result in
corresponding increases in transaction costs, may make it more difficult for the
Fund to qualify as a regulated investment company for federal income tax
purposes and may cause shareholders of the Fund to recognize gains for federal
income tax purposes. See 'Dividends, Distributions and Taxes -- Taxes.'
 
Assuming that the Allocation Model does not recommend a reallocation of assets
among the Segments, securities are sold from the Stock Segment only to reflect
certain administrative changes in the S&P 500 Index (including mergers or
changes in the composition of the S&P 500 Index) or to accommodate cash flows
into and out of the Fund while maintaining the similarity of the Stock Segment
to its benchmark. Similarly, assets are purchased or sold for each Segment
monthly, as described above, in order to accommodate cash flows and to rebalance
assets among the Segments.
 
- --------------------------------------------------------------------------------


                                   PURCHASES


- --------------------------------------------------------------------------------
 
Class Y shares (prior to November 10, 1995, called 'Class C' shares) are sold to
eligible investors at the net asset value next determined (see 'Valuation of
Shares') after the purchase order is received at PaineWebber's New York City
offices. No initial or contingent deferred sales charge is imposed, nor are
Class Y shares subject to Rule 12b-1 distribution or service fees. The Fund and
Mitchell Hutchins reserve the right to reject any purchase order and to suspend
the offering of the Class Y shares for a period of time.
 
INSIGHT.  An investor who purchases $50,000 or more of shares of the PaineWebber
mutual funds that are in the Flexible Pricing System may participate in INSIGHT,
a total portfolio asset allocation program sponsored by PaineWebber, and thus
become eligible to purchase Class Y shares. INSIGHT offers comprehensive
investment services, including a personalized asset allocation investment
strategy using an appropriate combination of funds, professional investment
advice regarding investment among the funds by portfolio specialists, monitoring
of investment performance and comprehensive quarterly reports that cover market
trends, portfolio summaries and personalized account information. Participation
in INSIGHT is subject to payment of an advisory fee to PaineWebber at the
maximum annual rate of 1.5% of assets held through the program (generally
charged quarterly in advance), which covers all INSIGHT investment advisory
services and program administration fees. Employees of PaineWebber and its
affiliates are entitled to a 50% reduction in the fee otherwise payable for
participation in INSIGHT. INSIGHT clients may elect to have their INSIGHT fees
charged to their PaineWebber accounts (by the automatic redemption of money
market fund shares) or another of their PaineWebber accounts or billed
separately.
 
ACQUISITION OF CLASS Y SHARES BY OTHERS.  Present holders of Class Y shares who
are not current INSIGHT participants may acquire Class A shares of the Fund
without a sales charge. This category includes former employees of Kidder,
Peabody & Co. Incorporated ('Kidder, Peabody'), their associated accounts,
present and former directors and trustees of the former Kidder, Peabody mutual
funds. The Fund is authorized to offer Class Y shares to employee benefit and
retirement plans of Paine Webber Group,

Inc., and its affiliates and certain other investment advisory programs that are
sponsored by PaineWebber and that may invest in PaineWebber mutual funds. At
present, however, INSIGHT participants are the only purchasers in these two
categories.
 
- --------------------------------------------------------------------------------


                                  REDEMPTIONS


- --------------------------------------------------------------------------------
 
As described below, Class Y shares may be redeemed at their net asset value and
redemption proceeds will be paid after receipt of a redemption request as
described below.
 
REDEMPTION THROUGH PAINEWEBBER OR CORRESPONDENT FIRMS.  PaineWebber clients may
submit redemption requests to their investment executives or correspondent firms
in person or by telephone, mail or wire. As the Fund's agent, PaineWebber may
honor a redemption request by repurchasing Fund shares from a redeeming
shareholder at the shares' net asset value next determined after receipt of the
request by PaineWebber's New York City offices. Within three Business Days after
receipt of the request, repurchase proceeds (less any applicable contingent
deferred sales charge) will be paid by check or credited to the shareholder's
brokerage account at the election of the shareholder. PaineWebber investment
executives and correspondent firms are responsible for promptly forwarding
redemption requests to PaineWebber's New York City offices.
 
PaineWebber reserves the right not to honor any redemption request, in which
case PaineWebber promptly will forward the request to the Transfer Agent for
treatment as described below.
 
REDEMPTION THROUGH THE TRANSFER AGENT.  Fund shareholders who are not
PaineWebber clients or who wish to redeem certificated shares must redeem their
shares through the Transfer Agent by mail; other shareholders also may redeem
Fund shares through the Transfer Agent. Shareholders should mail redemption
requests directly to the Transfer Agent: PFPC Inc., Attn: PaineWebber Mutual
Funds, P.O. Box 8950, Wilmington, Delaware 19899. A redemption request will be
executed at the net asset value next computed after it is received in 'good
order' and redemption proceeds will be paid within seven days of the receipt of
the request. 'Good order' means that the request must be accompanied by the
following: (1) a letter of instruction or a stock assignment specifying the
number of shares or amount of investment to be redeemed (or that all shares
credited to a Fund account be redeemed), signed by all registered owners of the
shares in the exact names in which they are registered, (2) a guarantee of the
signature of each registered owner by an eligible institution acceptable to the
Transfer Agent and in accordance with SEC rules, such as a commercial bank,
trust company or member of a recognized stock exchange, (3) other supporting
legal documents for estates, trusts, guardianships, custodianships, partnerships
and corporations and (4) duly endorsed share certificates, if any. Shareholders
are responsible for ensuring that a request for redemption is received in 'good
order.'
 
ADDITIONAL INFORMATION ON REDEMPTIONS.  A shareholder may have redemption
proceeds of $1 million or more wired to the shareholder's PaineWebber brokerage
account or a commercial bank account designated by the shareholder. Questions
about this option, or redemption requirements generally, should be referred to
the shareholder's PaineWebber investment executive or correspondent firm, or to
the Transfer Agent if the shares are not held in a PaineWebber brokerage
account. If a shareholder requests redemption of shares which were purchased
recently, the Fund may delay payment until it is assured that good payment has
been received. In the case of purchases by check, this can take up to 15 days.
 
Because the Fund incurs certain fixed costs in maintaining shareholder accounts,
the Fund reserves the right to redeem all Fund shares in any shareholder account
of less than $500 net asset value. If the Fund elects to do so, it will notify
the shareholder and provide the shareholder the opportunity to increase the
amount invested to $500 or more within 60 days of the notice. The Fund will not
redeem accounts that fall below $500 solely as a result of a reduction in net
asset value per share.

                       DIVIDENDS, DISTRIBUTIONS AND TAXES


- --------------------------------------------------------------------------------
 
DIVIDENDS AND DISTRIBUTIONS.  Dividends from net investment income and
distributions of net realized capital gains of the Fund, if any, are distributed
annually. Unless a shareholder instructs the Fund that dividends and capital
gains distributions on shares should be paid in cash and credited to the
shareholder's Account, dividends and capital gains distributions are reinvested
automatically at net asset value in additional shares. The Fund is subject to a
4% nondeductible excise tax measured with respect to certain undistributed
amounts of net investment income and capital gains. If necessary to avoid the
imposition of this tax, and if in the best interests of its shareholders, the
Fund will declare and pay dividends of its net investment income and
distributions of its net capital gains more frequently than stated above.
 
TAXES.  The Fund has qualified for the fiscal year ended August 31, 1995 to be
treated as a regulated investment company within the meaning of the Code and
intends to qualify for this treatment for each year. To qualify as a regulated
investment company for federal income tax purposes, the Fund limits its income
and investments so that (1) less than 30% of its gross income is derived from
the sale or disposition of stocks, other securities and certain financial
instruments (including certain forward contracts) that were held for less than
three months and (2) at the close of each quarter of the taxable year (a) not
more than 25% of the market value of the Fund's total assets is invested in the
securities (other than Government Securities) of a single issuer or of two or
more issuers controlled by the Fund that are engaged in the same or similar
trades or businesses or in related trades or businesses and (b) at least 50% of
the market value of the Fund's total assets is represented by (i) cash and cash
items, (ii) Government Securities and (iii) other securities limited in respect
of any one issuer to an amount not greater in value than 5% of the market value
of the Fund's total assets and to not more than 10% of the outstanding voting
securities of the issuer. The requirements for qualification may cause the Fund
to restrict the degree to which it sells or otherwise disposes of stocks, other
securities and certain financial instruments held for less than three months. If
the Fund qualifies as a regulated investment company and meets certain
distribution requirements, the Fund will not be subject to federal income tax on
its net investment income and net realized capital gains that it distributes to
its shareholders.
 
Dividends paid by the Fund out of net investment income and distributions of net
realized short-term capital gains are taxable to shareholders as ordinary
income, whether received in cash or reinvested in additional Fund shares.
Distributions of net realized long-term capital gains are taxable to
shareholders as long-term capital gain, regardless of how long shareholders have
held their shares and whether the distributions are received in cash or
reinvested in additional shares. Dividends and distributions paid by the Fund
generally do not qualify for the federal dividends received deduction for
corporate shareholders.
 
Statements as to the tax status of each Fund shareholder's dividends and
distributions are mailed annually. Shareholders also receive, as appropriate,
various written notices after the close of the Fund's taxable year regarding the
tax status of certain dividends and distributions that were paid (or that are
treated as having been paid) by the Fund to its shareholders during the
preceding taxable year, including the amount of dividends that represent
interest derived from Government Securities.
 
Shareholders are urged to consult their tax advisors regarding the application
of federal, state, local and foreign tax laws to their specific situations
before investing in the Fund.

                              VALUATION OF SHARES


- --------------------------------------------------------------------------------
 
Net asset value per share is calculated by the Fund's custodian, on each day,
Monday through Friday, except that net asset value is not computed on a day in
which no orders to purchase, sell, exchange or redeem Fund shares have been
received, any day on which there is not sufficient trading in the Fund's
portfolio securities that the Fund's net asset values per share might be
materially affected by changes in the value of such portfolio securities or on
days on which the NYSE is not open for trading. The NYSE is currently scheduled
to be closed on New Year's Day, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving and Christmas, and on the preceding
Friday when one of those holidays falls on a Saturday or on the subsequent
Monday when one of those holidays falls on a Sunday.

Net asset value per share is determined as of the close of regular trading on
the NYSE, and is computed by dividing the value of the Fund's net assets
attributable to that Class by the total number of shares outstanding of that
Class. Generally, the Fund's investments are valued at market value or, in the
absence of a market value, at fair value as determined by or under the direction
of the Trustees.
 
A security that is primarily traded on a stock exchange is valued at the last
sale price on that exchange or, if no sales occurred during the day, at the
current quoted bid price. Short-term investments that mature in 60 days or less
are valued on the basis of amortized cost (which involves valuing an investment
at its cost and, thereafter, assuming a constant amortization to maturity of any
discount or premium, regardless of the effect of fluctuating interest rates on
the market value of the investment) when the Board of Trustees has determined
that amortized cost represents fair value. An option that is written by the Fund
is generally valued at the last sale price or, in the absence of the last sale
price, the last offer price. An option that is purchased by the Fund is
generally valued at the last sale price or, in the absence of the last sale
price, the last bid price. The value of a futures contract is equal to the
unrealized gain or loss on the contract that is determined by marking the
contract to the current settlement price for a like contract on the valuation
date of the futures contract. A settlement price may not be used if the market
makes a limit move with respect to a particular futures contract or if the
securities underlying the futures contract experience significant price
fluctuations after the determination of the settlement price. When a settlement
price cannot be used, futures contracts will be valued at their fair market
value as determined by or under the direction of the Board of Trustees.

                                   MANAGEMENT


- --------------------------------------------------------------------------------
 
The Trust's board of trustees, as part of its overall management responsibility,
oversees various organizations responsible for the Fund's day-to-day management.
Mitchell Hutchins, the Fund's investment adviser and administrator, supervises
all aspects of the Fund's operations. Mitchell Hutchins receives a monthly fee
for its services, computed daily and payable monthly, at an annual rate of .50%
of the Fund's average daily net assets on assets up to but not including $250
million and .45% thereafter.
 
The Fund incurs other expenses and, for the fiscal year ended August 31, 1995,
the Fund's total expenses for its Class Y shares, stated as a percentage of
average net assets was 1.23%.
 
Mitchell Hutchins is located at 1285 Avenue of the Americas, New York, New York
10019. It is a wholly owned subsidiary of PaineWebber, which is in turn a wholly
owned subsidiary of Paine Webber Group Inc., a publicly owned financial services
holding company. As of Novemer 30, 1995, Mitchell Hutchins was adviser or sub-
adviser of 38 investment companies with 70 separate portfolios and aggregate
assets of over $29.6 billion.
 
As the Fund's investment adviser, Mitchell Hutchins manages the Fund's portfolio
in accordance with the investment objective and stated policies of the Fund and
makes investment decisions for the Fund. Mitchell Hutchins also provides the
Fund with investment officers who are authorized by the Trustees to determine
purchases and sales of securities on behalf of the Fund and employs a
professional staff of portfolio managers who draw upon a variety of sources for
research information for the Fund.
 
T. Kirkham Barneby is responsible for the asset allocation decisions for the
Fund. Mr. Barneby is a Managing Director and Chief Investment
Officer -- Quantitative Investments of Mitchell Hutchins. Mr. Barneby rejoined
Mitchell Hutchins in 1994, after being with Vantage Global Management for one
year. During the eight years that Mr. Barneby was previously with Mitchell
Hutchins, he was Senior Vice President responsible for quantitative management
and asset allocation models. Before joining Mitchell Hutchins, Mr. Barneby
served as Director of Pension Investment Strategy at the Continental Group in
Stamford, Connecticut and has held positions in the Economics Department at both
Citibank, N.A. and Merrill Lynch.
 
Although investment decisions for the Fund are made independently from those of
the other accounts managed by Mitchell Hutchins, investments of the type the
Fund may make may also be made by those other accounts. When the Fund and one or
more other accounts managed by Mitchell Hutchins are prepared to invest in, or
desire to dispose of, the same security, available investments or opportunities
for sales are allocated in a manner believed by Mitchell Hutchins to be
equitable to each. In some cases, this procedure may adversely affect the price
paid or received by the Fund or the size of the position obtained or disposed of
by the Fund.
 
Mitchell Hutchins investment personnel may engage in securities transactions for
their own accounts pursuant to each firm's code of ethics that establishes
procedures for personal investing and restricts certain transactions.
 
DISTRIBUTION ARRANGEMENTS.  Mitchell Hutchins is the distributor of the Fund's
Class Y shares and has appointed PaineWebber as the exclusive dealer for the
sale of those shares.

value of an investment in the Fund as a steady compound annual rate of return.
Actual year-by-year returns fluctuate and may be higher or lower than
standardized return. One-, five- and ten-year periods will be shown, unless the
shares have been in existence for a shorter period. Total return calculations
assume reinvestment of dividends and other distributions.
 
The Fund may use other total return presentations in conjunction with
standardized return. These may cover the same or different periods as those used
for standardized return and may include cumulative returns, average annual
rates, actual year-by-year rates or any combination thereof.
 
Total return and yield information reflects past performance and does not
necessarily indicate future results. Investment return and principal values will
fluctuate, and proceeds upon redemption may be more or less than a shareholder's
cost.

                              GENERAL INFORMATION


- --------------------------------------------------------------------------------
 
ORGANIZATION OF THE TRUST.  The Trust was formed as a business trust pursuant to
a Declaration of Trust, as amended from time to time (the 'Declaration'), under
the laws of The Commonwealth of Massachusetts on March 28, 1991. The Fund
commenced operations on July 22, 1992. The Declaration authorizes the Trust's
Board of Trustees to create separate series, and within each series separate
Classes, of an unlimited number of shares of beneficial interest, par value
$.001 per share. As of the date of this Prospectus, the Trustees have
established several such series, representing interests in the Fund described in
this Prospectus and in several other series.
 
When issued, Fund shares will be fully paid and non-assessable. Shares are
freely transferable and have no pre-emptive, subscription or conversion rights.
Each Class represents an identical interest in the Fund's investment portfolio.
As a result, the Classes have the same rights, privileges and preferences,
except with respect to: (1) the designation of each Class; (2) the effect of the
respective sales charges, if any, for each Class; (3) the distribution and/or
service fees, if any, borne by each Class; (4) the expenses allocable
exclusively to each Class; (5) voting rights on matters exclusively affecting a
single Class; and (6) the exchange privilege of each Class. The Board of
Trustees does not anticipate that there will be any conflicts among the
interests of the holders of the different Classes. The Trustees, on an ongoing
basis, will consider whether any conflict exists and, if so, take appropriate
action. Certain aspects of the shares may be changed, upon notice to Fund
shareholders, to satisfy certain tax regulatory requirements, if the change is
deemed necessary by the Trustees.
 
Shareholders of the Fund are entitled to one vote for each full share held and
fractional votes for fractional shares held. Voting rights are not cumulative
and, as a result, the holders of more than 50% of the aggregate shares of the
Trust may elect all of the Trustees. Generally, shares of the Trust will be
voted on a Trust-wide basis on all matters except those affecting only the
interests of one series, such as the Fund's management and investment advisory
agreement. In turn, shares of the Fund will be voted on a Fund-wide basis on all
matters except those affecting only the interests of one Class, such as the
terms of the Plan as it relates to a Class.
 
The Trust intends to hold no annual meetings of shareholders for the purpose of
electing Trustees unless, and until such time as, less 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 Trust may
remove a Trustee through a declaration in writing or by vote cast in person or
by proxy at a meeting called for that purpose. A meeting will be called for the
purpose of voting on the removal of a Trustee at the written request of holders
of 10% of the Trust's outstanding shares. Shareholders of the Fund who satisfy
certain criteria will be assisted by the Trust in communicating with other
shareholders in seeking the holding of the meeting.
 
To avoid additional operating costs and for investor convenience, the Fund does
not issue share certificates. Ownership of the Fund's shares is

recorded on a stock register by the Transfer Agent and shareholders have the
same rights of ownership with respect to such shares as if certificates had been
issued.
 
CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, One Heritage
Drive, North Quincy, Massachusetts 02171, is the custodian of the Fund's assets.

Fund's transfer and dividend disbursing agent.

and redemptions of Fund shares. PaineWebber clients receive statements at least
quarterly that report their Fund activity and consolidated year-end statements
that show all Fund transactions for that year. Shareholders who are not

Shareholders also receive audited annual and unaudited semi-annual financial
statements of the Fund.

                      STATEMENT OF ADDITIONAL INFORMATION
 
     PaineWebber  Tactical Allocation Fund  ('Fund') is a  diversified series of
Mitchell Hutchins/Kidder, Peabody Investment  Trust ('Trust'), a  professionally
managed  mutual  fund.  The Fund  seeks  total return,  consisting  of long-term
capital appreciation and  current income, by  utilizing a systematic  investment
strategy  that actively  allocates the Fund's  assets among  common stocks, U.S.
Treasury  Notes  and  U.S.  Treasury  Bills.  The  Fund's  investment   adviser,
administrator  and  distributor  is  Mitchell  Hutchins  Asset  Management  Inc.
('Mitchell Hutchins'),  a wholly  owned subsidiary  of PaineWebber  Incorporated
('PaineWebber').  As distributor for  the Fund, Mitchell  Hutchins has appointed
PaineWebber to serve as the exclusive dealer  for the sale of Fund shares.  This
Statement  of Additional Information is not a prospectus and should be read only
in conjunction with the Fund's current Prospectus, dated January 1, 1996. A copy
of the  Prospectus  may  be  obtained  by  calling  any  PaineWebber  investment
executive  or corresponding  firm or  by calling  toll-free 1-800-647-1568. This
Statement of Additional Information is dated January 1, 1996.
 
                      INVESTMENT POLICIES AND RESTRICTIONS
 
     The Prospectus  discusses the  investment  objective of  the Fund  and  the
policies  employed in achieving that  objective. Supplemental information is set
out below concerning certain  of the securities and  other instruments in  which
the  Fund may invest, the investment techniques and strategies that the Fund may
utilize and  certain  risks  involved with  those  investments,  techniques  and
strategies.
 
INVESTMENT TECHNIQUES AND STRATEGIES
 
     OPTIONS. To the extent required by the laws of certain states, the Fund may
not  be  permitted  to  commit more  than  5%  of its  assets  to  premiums when
purchasing call and put options on securities. Should these state laws change or
should the Fund obtain a waiver of  their application, the Fund may commit  more
than  5%  of its  assets to  premiums when  purchasing call  and put  options on
securities. In addition,  should the  Trust determine  that a  commitment is  no
longer  in the best interests  of the Fund and  its shareholders, the Trust will
revoke the commitment by terminating the sale of the Fund's shares in the  state
involved.
 
     FUTURES  CONTRACTS. The Fund may trade stock index futures contracts to the
extent permitted  under  rules  and interpretations  adopted  by  the  Commodity
Futures  Trading  Commission  (the  'CFTC'). U.S.  futures  contracts  have been
designed by exchanges  that have been  designated as 'contract  markets' by  the
CFTC,  and must be executed through  a futures commission merchant, or brokerage
firm, that is a member of the relevant contract market. Futures contracts  trade
on a number of contract markets,
 

<PAGE>
<PAGE>
and, through their clearing corporations, the exchanges guarantee performance of
the contracts as between the clearing members of the exchange.
 
     The  purpose  of trading  futures  contracts is  to  protect the  Fund from
fluctuations in  value  of its  investment  securities without  its  necessarily
buying  or selling  the securities. Because  the value of  the Fund's investment
securities will exceed the value of the  futures contracts sold by the Fund,  an
increase  in the  value of  the futures contracts  could only  mitigate, but not
totally offset, the decline in the value of the Fund's assets. No  consideration
is  paid or received by the Fund upon trading a futures contract. Upon trading a
futures contract, the Fund is required  to deposit in a segregated account  with
its  custodian an  amount of  cash, short-term U.S.  Treasury Bills  or Notes or
other high-grade, short-term money market instruments equal to approximately  1%
to  10% of the contract amount (this amount is subject to change by the exchange
on which the contract is  traded and brokers may  charge a higher amount).  This
amount  is known as 'initial margin' and is  in the nature of a performance bond
or good  faith  deposit on  the  contract that  is  returned to  the  Fund  upon
termination  of the futures contract,  assuming that all contractual obligations
have been  satisfied; the  broker will  have  access to  amounts in  the  margin
account  if  the  Fund fails  to  meet its  contractual  obligations. Subsequent
payments, known as 'variation margin,' to and from the broker, are made daily as
the price of the securities  underlying the futures contract fluctuates,  making
the  long and short positions  in the futures contract  more or less valuable, a
process known as 'marking-to-market.' At any  time prior to the expiration of  a
futures  contract, the Fund may elect to  close a position by taking an opposite
position, which will operate  to terminate the Fund's  existing position in  the
contract.
 
     Positions  in futures contracts may  be closed out only  on the exchange on
which they were undertaken (or through  a linked exchange). No secondary  market
for  futures contracts currently exists, and  although the Fund intends to trade
futures contracts only if an active market for them exists, no assurance can  be
given that an active market will exist for the contracts at any particular time.
Most  futures exchanges  limit the  amount of  fluctuation permitted  in futures
contract prices  during a  single trading  day. Once  the daily  limit has  been
reached  in a particular contract, no trades may  be made on that day at a price
beyond that limit. Prices for futures contracts may move to the daily limit  for
several  consecutive trading days with little  or no trading, thereby preventing
prompt liquidation of futures positions  and subjecting the Fund to  substantial
losses.  In that  case, and in  the event  of adverse price  movements, the Fund
would be  required to  make daily  cash payments  of variation  margin. In  such
circumstances,  an increase in the value of the portion of the Fund's securities
being hedged, if any, may partially  or completely offset losses on the  futures
contract.
 
     OPTIONS  ON FUTURES CONTRACTS. The Fund may purchase and write put and call
options on stock index future  contracts that are traded  on a U.S. exchange  or
board  of trade or a  foreign exchange, to the  extent permitted under rules and
interpretations of the CFTC,  as a hedge against  changes in market  conditions,
and  may  enter  into closing  transactions  with  respect to  those  options to
terminate existing  positions.  No  assurance  can be  given  that  the  closing
transactions can be effected.
 
     LENDING  PORTFOLIO SECURITIES.  The Fund  may lend  portfolio securities to
well-known and recognized  U.S. and  foreign brokers, dealers  and banks.  These
loans,  if and when  made, may not exceed  30% of the value  of the Fund's total
assets. The Fund's loans of securities  will be collateralized by cash,  letters
of  credit  or securities  issued  and guaranteed  by  the U.S.  Government, its
agencies, authorities or instrumentalities  ('Government Securities'). The  cash
or instruments collateralizing the Fund's loans of securities will be maintained
at  all  times in  a segregated  account with  the Fund's  custodian, or  with a
 
                                       2
 

<PAGE>
<PAGE>
designated sub-custodian, in  an amount  at least  equal to  the current  market
value  of the loaned securities. From  time to time, the Fund  may pay a part of
the interest earned from  the investment of  collateral received for  securities
loaned  to the borrower and/or a third  party that is unaffiliated with the Fund
and is acting as a 'finder.' The Fund will comply with the following  conditions
whenever  it loans  securities: (1)  the Fund  must receive  at least  100% cash
collateral or equivalent  securities from  the borrower; (2)  the borrower  must
increase the collateral whenever the market value of the securities loaned rises
above  the level of the  collateral; (3) the Fund must  be able to terminate the
loan at any time; (4) the Fund must receive reasonable interest on the loan,  as
well as any dividends, interest or other distributions on the loaned securities,
and any increase in market value; (5) the Fund may pay only reasonable custodian
fees in connection with the loan; and (6) voting rights on the loaned securities
may  pass to the borrower  except that, if a  material event adversely affecting
the investment in the  loaned securities occurs, the  Trust's Board of  Trustees
must terminate the loan and regain the right to vote the securities.
 
     WHEN-ISSUED  AND  DELAYED-DELIVERY  SECURITIES. When  the  Fund  engages in
when-issued or delayed-delivery securities transactions, it relies on the  other
party  to consummate the trade. Failure of the seller to do so may result in the
Fund's incurring a loss or missing  an opportunity to obtain a price  considered
to be advantageous.
 
INVESTMENT RESTRICTIONS
 
     Investment  restrictions numbered 1  through 10 below  have been adopted by
the Trust as fundamental policies with respect to the Fund. Under the Investment
Company Act of 1940, as amended (the  '1940 Act'), a fundamental policy may  not
be  changed without the vote of a  majority of the outstanding voting securities
of the Fund,  as defined in  the 1940 Act.  Investment restrictions numbered  11
through  17 may  be changed  by a  vote of  a majority  of the  Trust's Board of
Trustees at any time.
 
     Under the investment restrictions adopted by the Trust with respect to  the
Fund:
 
          1.  The  Fund  will  not purchase  securities  (other  than Government
     Securities) of any issuer if, as a result of the purchase, more than 5%  of
     the value of the Fund's total assets would be invested in the securities of
     the  issuer, except that up to 25% of  the value of the Fund's total assets
     may be invested without regard to this 5% limitation.
 
          2. The Fund will not purchase  more than 10% of the voting  securities
     of  any one issuer, or more than 10%  of the securities of any class of any
     one issuer, except  that this limitation  is not applicable  to the  Fund's
     investments  in Government Securities,  and up to 25%  of the Fund's assets
     may be invested without regard to these 10% limitations.
 
          3. The Fund  will not borrow  money, except that  the Fund may  borrow
     from  banks for temporary or emergency (not leveraging) purposes, including
     the meeting  of redemption  requests  and cash  payments of  dividends  and
     distributions  that  might otherwise  require  the untimely  disposition of
     securities, in an amount not to exceed 20% of the value of the Fund's total
     assets (including the  amount borrowed) valued  at market less  liabilities
     (not  including the  amount borrowed)  at the  time the  borrowing is made.
     Whenever borrowings exceed 5% of the value of the total assets of the Fund,
     the Fund will not make any additional investments.

<PAGE>
<PAGE>
          4. The  Fund will  not lend  money to  other persons,  except  through
     purchasing  debt obligations, lending portfolio securities in an amount not

thereof,  (17) the cost of investment  company literature and other publications
provided to trustees  and officers  and (18)  costs of  mailing, stationery  and
communications equipment.
 
     For  the fiscal years ended August 31, 1995, August 31, 1994 and August 31,
1993, the Trust paid (or  accrued) management fees with  respect to the Fund  of
$279,950; $505,878; and $419,426, respectively, to the Fund's investment adviser
and administrator during those periods.
 
     Mitchell  Hutchins has agreed that, if in  any fiscal year of the Fund, the
aggregate expenses  of  the  Fund  (including  management  fees,  but  excluding
interest,  taxes, brokerage and, with the prior written consent of the necessary
state  securities  commissions,  extraordinary  expenses)  exceed  the   expense
limitation  of any state  having jurisdiction over  the Trust, Mitchell Hutchins
will reimburse  the Trust  for the  excess expense.  This expense  reimbursement
obligation  is  limited  to the  amount  of  Mitchell Hutchins'  fees  under its
respective agreement  with  the  Trust  in respect  of  the  Fund.  Any  expense
reimbursement  will be estimated, reconciled and paid  on a monthly basis. As of
the date of this Statement of Additional Information, the most restrictive state
expense limitation applicable to the Fund requires reimbursement of expenses  in
any year that the Fund's expenses subject to the limitation exceed 2 1/2% of the
first $30 million of the average daily value of the Fund's net assets, 2% of the
next  $70 million of the average daily value of the Fund's net assets and 1 1/2%
of the remaining average daily  value of the Fund's  net assets. For the  fiscal
year ended August 31, 1995, the Fund's expenses did not exceed such limitations.
 
     Under  its  agreement  with the  Trust  in  respect of  the  Fund, Mitchell
Hutchins will not be liable for any error  of judgment or mistake of law or  for
any  loss suffered by the Trust with respect  to the Fund in connection with the
matters to which the agreement relates, except for 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  the
agreement.
 
     Mitchell Hutchins personnel may invest in securities for their own accounts
pursuant  to  a  code  of  ethics that  describes  the  fiduciary  duty  owed to
shareholders of  the  PaineWebber  mutual funds  and  other  Mitchell  Hutchins'
advisory  accounts by all Mitchell  Hutchins' directors, officers and employees,
establishes  procedures   for   personal   investing   and   restricts   certain
transactions. For example, employee
 
                                       8
 

<PAGE>
<PAGE>
accounts  generally must be  maintained at PaineWebber,  personal trades in most
securities require  pre-clearance and  short-term trading  and participation  in
initial  public offerings  generally are  prohibited. In  addition, the  code of
ethics puts restrictions  on the  timing of  personal investing  in relation  to
trades by PaineWebber and other Mitchell Hutchins advisory clients.
 
DISTRIBUTION ARRANGEMENTS
 
     Mitchell Hutchins acts as the distributor of the Class Y shares of the Fund
under  a distribution contract with the Trust that requires Mitchell Hutchins to
use its best efforts,  consistent with its other  businesses, to sell shares  of
the Fund. Shares of the Fund are offered continuously. Under an exclusive dealer
agreement  between Mitchell Hutchins and PaineWebber  relating to Class Y shares
of the Fund,  PaineWebber and its  correspondent firms sell  the Fund's Class  Y
shares.
 
                             PORTFOLIO TRANSACTIONS
 
     Decisions  to buy  and sell  securities for the  Fund are  made by Mitchell
Hutchins, subject to review  by the Trust's Board  of Trustees. Transactions  on
domestic stock exchanges and some foreign stock exchanges involve the payment of
negotiated   brokerage  commissions.  On  exchanges  on  which  commissions  are
negotiated, the cost of transactions may  vary among different brokers. On  most
foreign exchanges, commissions are generally fixed.
 
     Subject to policies established by the Board of Trustees, Mitchell Hutchins
is  responsible for the  execution of the Fund's  portfolio transactions and the
allocation of  brokerage  transactions.  In  executing  portfolio  transactions,
Mitchell Hutchins seeks to obtain the best net results for the Fund, taking into
account  such factors as price (including the applicable brokerage commission or
dealer  spread),  size  of  order,  difficulty  of  execution  and   operational
facilities  of the firm involved. Generally, bonds  are traded on the OTC market
on a 'net' basis  without a stated commission  through dealers acting for  their
own account and not as brokers. Prices paid to dealers in principal transactions
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  the
time. For the fiscal years ended August 31, 1995, August 31, 1994 and August 31,
1993,  the Fund paid  $82,091; $56,965; and  $58,975, respectively, in aggregate
brokerage commissions.
 
     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, brokerage transactions may be
conducted through Mitchell  Hutchins or its  affiliates, including  PaineWebber.
The  Trust'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  and  its  affiliates  are  reasonable  and  fair.  Specific
provisions in the Advisory Contract authorize  Mitchell Hutchins and any of  its
affiliates  that  are  members  of  a  national  securities  exchange  to effect
portfolio transactions for the Fund on such exchange and to retain  compensation
in connection with such transactions. Any such transactions will be effected and
related  compensation paid only  in accordance with  applicable SEC regulations.
For the  fiscal  year  ended  August  31,  1995,  the  Fund  paid  no  brokerage
commissions to PaineWebber.
 
     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  Fund's  transactions in
futures   contracts,    including    procedures   permitting    the    use    of
 
                                       9
 

<PAGE>
<PAGE>
Mitchell  Hutchins  and its  affiliates,  are similar  to  those in  effect with
respect to brokerage transactions in securities.
 
     Consistent with the interest of the Fund  and subject to the review of  the
board  of trustees, Mitchell  Hutchins may cause  the Fund to  purchase and sell
portfolio securities  through  brokers  who  provide  the  Fund  with  research,
analysis, advice and similar services. In return for such services, the Fund may
pay  to those brokers a higher commission  than may be charged by other brokers,
provided that Mitchell Hutchins determines in good faith that such commission is
reasonable in terms  either of  that particular  transaction or  of the  overall
responsibility  of Mitchell Hutchins to the Fund  and its other clients and that
the total commissions paid  by the Fund  will be reasonable  in relation to  the
benefits  to  the  Fund  over  the  long  term.  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,  Mitchell 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 provided
research or  execution  services.  These procedures  include  Mitchell  Hutchins
receiving  multiple quotes from  dealers before executing  the transaction on an
agency basis.
 
     Research services furnished by the brokers or dealers through which or with
which the Fund effects securities transactions may be used by Mitchell  Hutchins
in advising other funds or accounts and, conversely, research services furnished
to  Mitchell Hutchins by  brokers or dealers  in connection with  other funds or
accounts that Mitchell  Hutchins advises  may be  used by  Mitchell Hutchins  in
advising  the  Fund.  Information and  research  received from  such  brokers or
dealers will be in addition to, and not in lieu of, the services required to  be
performed by Mitchell Hutchins under the Management Agreement.
 
     Investment decisions for the Fund and for other investment accounts managed
by  Mitchell Hutchins 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 the Fund 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 Fund and such other account(s) as
to  amount according to  a formula deemed  equitable to the  Fund and such other
account(s). While in some  cases this practice could  have a detrimental  effect
upon  the price or value of the security as far as the Fund 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 Fund.
 
     The Fund will not  purchase securities in  underwritings in which  Mitchell
Hutchins  or any of  its affiliates is  a member of  the underwriting or selling
group, except  pursuant to  procedures  adopted by  the Corporation's  board  of
directors  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
 
                                       10

the first business day after the date  of the public offering and that  Mitchell
Hutchins or any affiliate thereof not participate in or benefit from the sale to
the Fund.
 
     PORTFOLIO  TURNOVER. The portfolio turnover  rate is calculated by dividing
the lesser  of the  Fund'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  in the portfolio during the year.  For the fiscal years ended August
31, 1995 and  August 31,  1994, the  portfolio turnover  rate for  the Fund  was
53.02%  and 4.17%, respectively. The higher  turnover for the most recent fiscal
year was due  to reallocations  during that period  of the  Fund's portfolio  in
accordance with the Fund's systematic asset allocation strategy.
 
                              VALUATION OF SHARES
 
     The Fund determines the net asset value per share separately for each Class
of shares as of the close of regular trading (currently 4:00 p.m., Eastern time)
on the NYSE on each Business Day, which is defined as each Monday through Friday
when  the NYSE is open.  Currently, the NYSE is closed  on the observance of the
following holidays: New Year's Day, Presidents' Day, Good Friday, Memorial  Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
 
     Securities  that are listed on 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 the Sub-Adviser  as the primary market.  Securities traded in the
OTC market and listed on Nasdaq are  valued at the last available sale price  on
Nasdaq  at 4:00 p.m., Eastern time; other  OTC securities are valued at the last
bid price available prior to valuation.
 
     Where market quotations, are readily available, debt securities are  valued
based upon those quotations, provided such quotations adequately reflect, in the
Sub-Adviser's judgment, fair value of the security. Where such market quotations
are  not readily  available, such  securities are  valued based  upon appraisals
received from a  pricing service using  a computerized matrix  system, or  based
upon  appraisals  derived from  information concerning  the security  or similar
securities received  from  recognized dealers  in  those securities.  All  other
securities or assets will be valued at fair value as determined in good faith by
or  under the  direction of  the Trust'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 Trust's board of trustees determines that
this does not represent fair value.
 
                            PERFORMANCE INFORMATION
 
     The  Fund's performance  data quoted  in advertising  and other promotional
materials ('Performance Advertisements') represent past performance and are  not
intended  to indicate  future performance.  The investment  return and principal
value of  an  investment will  fluctuate  so  that an  investor's  shares,  when
redeemed, may be worth more or less than their original cost.

     TOTAL  RETURN. Average  annual total return  quotes ('Standardized Return')
used in the Fund's  Performance Advertisements are  calculated according to  the
following formula:
 
<TABLE>
<S>                      <C>
     P(1 + T)'pp'n  =     ERV
where:        P     =     a hypothetical initial payment of $1,000 to purchase shares of a specified Class
              T     =     average annual total return of shares of that Class
              n     =     number of years
              ERV   =     ending redeemable value of a hypothetical $1,000 payment made at the
                          beginning of that period.
</TABLE>
 
     Under   the  foregoing  formula,  the  time  periods  used  in  Performance
Advertisements will be based on rolling  calendar quarters, updated to the  last
day  of the  most recent  quarter prior to  submission of  the advertisement for
publication. Total return, or 'T' in  the formula above, is computed by  finding
the  average annual change in the value of an initial $1,000 investment over the
period. In  calculating the  ending redeemable  value for  Class A  shares,  the
Fund's  maximum 4.5%  initial sales charge  is deducted from  the initial $1,000
payment and, for Class B and Class C shares, the applicable contingent  deferred
sales  charge imposed on a redemption of Class B and Class C shares held for the
period is deducted. All  dividends and other distributions  are assumed to  have
been reinvested at net asset value.
 
     The  Fund  also may  refer in  Performance  Advertisements to  total return
performance data that  are not  calculated according  to the  formula set  forth
above  ('Non-Standardized Return'). The  Fund calculates Non-Standardized Return
for specified  periods of  time by  assuming the  investment of  $1,000 in  Fund
shares  and assuming the reinvestment of  all dividends and other distributions.
The rate  of  return is  determined  by subtracting  the  initial value  of  the
investment  from the ending value  and by dividing the  remainder by the initial
value. Neither  initial nor  contingent deferred  sales charges  are taken  into
account  in calculating Non-Standardized Return;  the inclusion of these charges
would reduce the return.
 
     Both Standardized Return and Non-Standardized Return for Class B shares for
periods of over six years will reflect conversion of the Class B shares to Class
A shares at the end of the sixth year.
 
     The following table shows performance information for the Class A, Class  C
and Class Y shares of the Fund for the periods indicated. No Class B shares were
outstanding  during those periods. All returns for periods of more than one year
are expressed as an average return.

 * All Standardized Return figures for Class  A shares reflect deduction of  the
   current  maximum sales charge of 4.5%. Class  C shares impose a 1% contingent
   deferred sales charge  only on redemptions  made within a  year of  purchase;
   therefore,  for  periods longer  than  one year,  Non-Standardized  Return is
   identical to Standardized Return.
 
** The inception date for  the Class A and  Class Y shares is  May 10, 1993  and
   July 22, 1992 for Class C shares.
 
     OTHER  INFORMATION. In Performance Advertisements, the Fund may compare its
Standardized Return and/or  its Non-Standardized Return  with data published  by
Lipper  Analytical Services,  Inc. ('Lipper')  for growth  funds; CDA Investment
Technologies,  Inc.   ('CDA');   Wiesenberger   Investment   Companies   Service
('Wiesenberger');  Investment Company  Data Inc. ('ICD');  or Morningstar Mutual
Funds ('Morningstar'); or  with the  performance of recognized  stock and  other
indexes,  including (but  not limited  to) the  Standard &  Poor's 500 Composite
Stock Price Index, the Dow Jones Industrial Average, the NASDAQ Composite Index,
the Russell 2000 Index,  the Russell 1000 Index,  the Wilshire Small Cap  Index,
PSI  Small Cap  Index, the  Lehman Brothers  20+ Year  Treasury Bond  Index, the
Lehman Brothers Government/Corporate Bond  Index, the Salomon Brothers  Non-U.S.
World  Government  Bond  Index,  and  changes in  the  Consumer  Price  Index as
published by the U.S. Department  of Commerce. The Fund  also may refer in  such
materials   to  mutual  fund  performance  rankings  and  other  data,  such  as
comparative  asset,  expense   and  fee  levels,   published  by  Lipper,   CDA,
Wiesenberger,  ICD or Morningstar. Performance  Advertisements also may refer to
discussions of the Fund and comparative mutual fund data and ratings reported in
independent periodicals, including (but not limited to) THE WALL STREET JOURNAL,
MONEY Magazine, FORBES, BUSINESS WEEK,  FINANCIAL WORLD, BARRON'S, FORTUNE,  THE
NEW  YORK  TIMES, THE  CHICAGO TRIBUNE,  THE WASHINGTON  POST and  THE KIPPINGER
LETTERS. Comparisons in Performance Advertisements may be in graphic form.
 
     The Fund  may  include  discussions  or illustrations  of  the  effects  of
compounding  in  Performance Advertisements.  'Compounding'  refers to  the fact
that, if dividends or other distributions on a Fund investment are reinvested by
being paid in additional Fund shares, any future income or capital  appreciation
of  the Fund would increase the value, not only of the original Fund investment,
but also  of the  additional Fund  shares received  through reinvestment.  As  a
result,  the value of  the Fund investment  would increase more  quickly than if
dividends or other distributions had been paid in cash.
 
     The Fund may  also compare  its performance  with the  performance of  bank
certificates  of deposits (CDs) as measured  by the CDA Investment Technologies,
Inc. Certificate of Deposit Index, the Bank Rate Monitor National Index and  the
averages  of  yields  of CDs  of  major  banks published  by  Banxquote'r' Money
Markets. In comparing the Fund's performance to CD performance, investors should
keep in mind that bank CDs are insured in  whole or in part by an agency of  the
U.S.  government  and  offer fixed  principal  and  fixed or  variable  rates of
interest,  and  that  bank  CD  yields  may  vary  depending  on  the  financial
institution  offering the CD and prevailing  interest rates. Fund shares are not
insured or guaranteed by the U.S.  government and returns thereon and net  asset
value will fluctuate. The debt securities held by the Fund generally have longer
maturities  than most CDs and may  reflect interest rate fluctuations for longer
term securities.  An investment  in  the Fund  involves  greater risks  than  an
investment in either a money market fund or a CD.

                                     TAXES
 
     Set forth below is a summary of certain income tax considerations generally
affecting  the  Fund and  its shareholders.  The  summary is  not intended  as a
substitute for individual tax  planning, and shareholders  are urged to  consult
their  tax  advisors  regarding the  application  of federal,  state,  local and
foreign tax laws to their specific tax situations.
 
TAX STATUS OF THE FUND AND ITS SHAREHOLDERS
 
     The Fund  will be  treated as  a  separate entity  for federal  income  tax
purposes. The Fund's net investment income, capital gains and distributions will
be determined separately from any other series that the Trust may designate.
 
     The  Fund has  qualified for the  fiscal year  ended August 31,  1995 to be
treated as a 'regulated investment company'  under the Internal Revenue Code  of
1986,  as  amended (the  'Code') and  intends  to continue  to qualify  for this
treatment for each year. If the Fund  (1) is a regulated investment company  and
(2)  distributes to its shareholders  at least 90% of  its net investment income
(including for this purpose its net realized short-term capital gains), the Fund
will not  be  liable  for federal  income  taxes  to the  extent  that  its  net
investment  income and its net realized  long-term and short-term capital gains,
if any, are distributed to its shareholders.
 
     The Fund's transactions  in options  and futures contracts  are subject  to
special  provisions  of  the  Code  that, among  other  things,  may  affect the
character of gains and losses realized by the Fund (that is, may affect  whether
gains  or losses are  ordinary or capital), accelerate  recognition of income to
the Fund and  defer Fund  losses. These rules  (1) could  affect the  character,
amount and timing of distributions to shareholders of the Fund, (2) will require
the  Fund to 'mark  to market' certain  types of the  positions in its portfolio
(that is, treat them as if they were closed out), and (3) may cause the Fund  to
recognize  income without  receiving cash  with which  to make  distributions in
amounts necessary to satisfy the  distribution requirements for avoiding  income
and  excise  taxes described  above and  in  the Prospectus.  The Fund  seeks to
monitor its transactions, seeks to make the appropriate tax elections and  seeks
to  make the appropriate entries  in its books and  records when it acquires any
futures contract or hedged investment, to mitigate the effect of these rules and
prevent disqualification of the Fund as a regulated investment company.
 
     If the Fund is the holder of record of any stock on the record date for any
dividends payable with respect to such stock, such dividends are included in the
Fund's gross  income  as  of  the  later of  (1)  the  date  such  stock  became
ex-dividend  with respect to such dividends (i.e.,  the date on which a buyer of
the stock would not be entitled to receive the declared, but unpaid,  dividends)
or  (2) the date the Fund acquired  such stock. Accordingly, in order to satisfy
its income distribution requirements, the Fund may be required to pay  dividends
based  on anticipated  earnings, and  shareholders may  receive dividends  in an
earlier year than would otherwise be the case.
 
     As a general rule, a shareholder's gain or loss on a sale or redemption  of
Fund  shares is a long-term capital gain or loss if the shareholder has held the
shares for more than one year. The gain or loss is a short-term capital gain  or
loss if the shareholder has held the shares for one year or less.
 
     The  Fund's  net  realized  long-term  capital  gains  are  distributed  as
described in the  Prospectus. The distributions  ('capital gain dividends'),  if
any,  are taxable to shareholders as  long-term capital gains, regardless of how
long a shareholder  has held  Fund shares, and  are designated  as capital  gain
dividends
 
                                       14
 

<PAGE>
<PAGE>
in  a written notice mailed  by the Trust to the  shareholders of the Fund after
the close of the Fund's prior taxable year. If a shareholder receives a  capital
gain dividend with respect to any Fund share, and if the share is sold before it
has  been held by the shareholder for more than six months, then any loss on the
sale or exchange of the  share, to the extent of  the capital gain dividend,  is
treated as a long-term capital loss.
 
     Investors  considering buying  Fund shares on  or just prior  to the record
date for a taxable  dividend or capital gain  distribution should be aware  that
the amount of the forthcoming dividend or distribution payment will be a taxable
dividend or distribution payment.
 
     Special  rules  contained in  the Code  apply when  a Fund  shareholder (1)
disposes of shares of the Fund through  a redemption or exchange within 90  days
of purchase and (2) subsequently acquires shares of a PaineWebber mutual fund on
which  a  sales charge  normally is  imposed  without paying  a sales  charge in
accordance with the  exchange privilege  described in the  Prospectus. In  these
cases,  any gain  on the disposition  of the  Fund shares is  increased, or loss
decreased, by the amount of the sales charge paid when the shares were acquired,
and that amount will increase the adjusted basis of the fund shares subsequently
acquired. In addition, if  shares of the  Fund are purchased  within 30 days  of
redeeming shares at a loss, the loss is not deductible and instead increases the
basis of the newly purchased shares.
 
     If  a  shareholder  fails to  furnish  the  Trust with  a  correct taxpayer
identification number, fails  to report  fully dividend or  interest income,  or
fails  to certify that he or she  has provided a correct taxpayer identification
number and that  he or  she is  not subject  to 'backup  withholding,' then  the
shareholder  may be subject to 31% 'backup  withholding' tax with respect to (1)
taxable dividends and distributions  from the Fund and  (2) the proceeds of  any
redemptions  of Fund shares.  An individual's taxpayer  identification number is
his or  her  social  security number.  The  backup  withholding tax  is  not  an
additional  tax and may be credited  against a taxpayer's regular federal income
tax liability.
 
                               OTHER INFORMATION
 
     The Trust  was  organized  as  a  business trust  under  the  laws  of  The
Commonwealth of Massachusetts pursuant to a Declaration of Trust dated March 28,
1991,  as  amended from  time to  time (the  'Declaration'). The  Fund commenced
operations on July 22, 1992. Prior to November 1, 1995, the name of the Fund was
'Mitchell Hutchins/Kidder, Peabody Asset Allocation Fund.' Prior to February 13,
1995, the name of the Fund was 'Kidder, Peabody Asset Allocation Fund.' Prior to
November 10, 1995, the Fund's  Class C shares were  called 'Class B' shares  and
Class Y shares were called 'Class C' shares. New Class B shares were not offered
prior to January 1, 1996.
 
     Massachusetts  law  provides that  shareholders of  the Trust  could, under
certain circumstances,  be held  personally liable  for the  obligations of  the
Trust.  The Declaration disclaims shareholder  liability for acts or obligations
of the Trust, however, and  requires that notice of  the disclaimer be given  in
each  agreement, obligation or instrument entered  into or executed by the Trust
or a  Trustee. The  Declaration provides  for indemnification  from the  Trust's
property  for  all losses  and expenses  of  any shareholder  of the  Trust held
personally liable for the  obligations of the  Trust. Thus, the  risk of a  Fund
shareholder  incurring  financial loss  on account  of shareholder  liability is
limited to  circumstances  in  which the  Trust  would  be unable  to  meet  its
obligations,  a possibility that the Trust's management believes is remote. Upon
payment of  any liability  incurred by  the Trust,  the shareholder  paying  the
liability  will  be entitled  to reimbursement  from the  general assets  of the
Trust. The Trustees intend to
 
                                       15
 

<PAGE>
<PAGE>
conduct the operations of  the Trust in  such a way  so as to  avoid, as far  as
possible, ultimate liability of the shareholders for liabilities of the Trust.
 
     CLASS-SPECIFIC  EXPENSES. The Fund  might determine to  allocate certain of
its expenses (in addition to distribution  fees) to the specific Classes of  the
Fund's  shares to  which those expenses  are attributable. For  example, Class B
shares of the  Funds bear higher  transfer agency fees  per shareholder  account
than  those borne by Class A or Class C shares. The higher fee is imposed due to
the higher costs incurred by the Transfer Agent in tracking shares subject to  a
contingent  deferred sales charge because, upon  redemption, the duration of the
shareholder's investment must be determined in order to determine the applicable
charge. Moreover,  the  tracking  and calculations  required  by  the  automatic
conversion  feature of the Class B shares will cause the Transfer Agent to incur
additional costs. Although the transfer agency fee will differ on a per  account
basis  as stated above,  the specific extent  to which the  transfer agency fees
will differ between the Classes  as a percentage of  net assets is not  certain,
because  the fee as a percentage of net assets will be affected by the number of
shareholder accounts in  each Class and  the relative amounts  of net assets  in
each Class.
