UBS HIGH YIELD BOND FUND
INVESTORS FOR WHOM THE FUND IS DESIGNED
 
UBS High Yield Bond Fund (the 'Fund') is designed for investors seeking higher
current income from a portfolio of higher-yielding, lower-rated debt securities
issued by domestic and foreign companies than that generally available from a
portfolio of higher-rated obligations in exchange for assuming additional risk
of capital. The Fund will also seek capital appreciation when consistent with
high current income by investing in securities benefiting from declines in
long-term interest rates or improvements in credit quality. The Fund seeks to
achieve its investment objectives by investing all of its investable assets in
UBS High Yield Bond Portfolio (the 'Portfolio'). The Portfolio is a series of
UBS Investor Portfolios Trust (the 'Trust'), an open-end management investment
company. The Portfolio has the same investment objective as the Fund. Because
the investment characteristics and experience of the Fund will correspond
directly with those of the Portfolio, the discussion in this Prospectus focuses
on the investments and investment policies of the Portfolio. The net asset value
of shares of the Fund fluctuates with changes in the value of the investments in
the Portfolio. See 'Investment Objective and Policies -- Quality Information.'
 
The Portfolio may make various types of investments in seeking its objectives.
Among the permissible investments for the Portfolio are high-yielding,
lower-rated bonds and debt instruments of domestic and foreign companies. The
Portfolio may also invest in futures contracts, options, forward contracts on
foreign currencies, certain privately placed securities and equity securities
such as common and preferred stocks. For further information about these
investments and related investment techniques, see 'Investment Objective and
Policies' discussed below.
 
The minimum initial investment in the Fund is $25,000, except that the minimum
initial investment is $10,000 for shareholders of another series of UBS Private
Investor Funds, Inc. (the 'Company'). The minimum subsequent investment for all
investors is $5,000. These minimums may be waived at the Fund's discretion. See
'Purchase of Shares.' If shareholders reduce their total investment in shares of
the Fund to less than $10,000, their investment will be subject to mandatory
redemption. See 'Redemption of Shares -- Mandatory Redemption.' The Fund is one
of several series of the Company, an open-end management investment company
organized as a Maryland corporation.
 
This Prospectus describes the Fund's investment objective and policies,
management and operations to enable investors to decide if the Fund suits their
investment needs. The Fund operates through a two-tier master-feeder investment
fund structure. The Company's Board of Directors (the 'Directors' or the
'Board') believes that this structure provides Fund shareholders with the
opportunity to achieve certain economies of scale that would otherwise be
unavailable if the shareholders' investments were not pooled with other
investors sharing similar investment objectives.
 
The following table illustrates that Fund investors incur no shareholder
transaction expenses: their investments in the Fund are subject only to the
operating expenses set forth below for the Fund and the Portfolio, as a
percentage of average daily net assets of the Fund. The Directors believe that
the aggregate per share expenses of the Fund and the Portfolio will be
approximately equal to and may be less than the expenses that the Fund would
incur if it retained the services of an investment adviser and invested its
assets directly in portfolio securities. Fund and Portfolio expenses are
discussed below under the headings 'Management', 'Expenses' and 'Shareholder
Services.'

*   Expenses are expressed as a percentage of the Fund's projected average daily
net assets and are based on annualized estimates of expenses to be incurred
during the fiscal period ending December 31, 1997, after any applicable fee
waivers and expense reimbursements. Without such fee waivers and expense
reimbursements, Total Operating Expenses are estimated to be equal, on an annual
basis, to 1.95% of the Fund's average daily net assets. See 'Management'.
 
**  The New York Branch (the 'Branch' or the 'Adviser') of Union Bank of
Switzerland (the 'Bank') has agreed to waive fees and reimburse the Fund and the
Portfolio for any of its respective operating expenses to the extent that the
Fund's total operating expenses (including its share of the Portfolio's
expenses) exceed, on an annual basis, 0.90% of the Fund's average daily net
assets. The Branch may modify or discontinue this undertaking at any time in the
future with 30 days' prior notice to the Fund. The Portfolio's advisory fee
would be equal, on an annual basis, to 0.45% of the average daily net assets of
the Portfolio if there were no fee waiver in effect. See 'Management -- Adviser
and Funds Services Agent' and 'Expenses'.
 
*** The fees and expenses in Other Expenses include fees payable to:
 
    (i) Investors Bank & Trust Company ('Investors Bank', the 'Custodian', or
    the 'Transfer Agent') (a) under an Administration Agreement with the Fund,
    (b) as custodian of the Fund and the Portfolio and (c) as transfer agent of
    the Fund,
 
    (ii) Investors Fund Services (Ireland) Limited ('IBT Ireland') under an
    Administration Agreement with the Portfolio, and
 
    (iii) Eligible Institutions providing shareholder services under various
    shareholder servicing agreements.

waivers and expense reimbursements, and of the fees and expenses included in
Other Expenses, see 'Management' and 'Shareholder Services'.

return during the same periods for the Merrill Lynch All
High Yield Bond Index (the 'Index'). The discretionary accounts described in (i)
above have substantially the same investment objective and policies and are
managed in a manner substantially the same as the Portfolio. The composite total
returns for such accounts have been adjusted to deduct all of the Fund's annual
total operating expenses of 0.90% of average daily net assets as set forth in
the Expense Table above. The composite total returns are time-weighted and
weighted by individual account size and reflect the reinvestment of interest.
The discretionary accounts are not subject to certain investment limitations,
diversification requirements and other restrictions imposed by federal
securities and tax laws on the Portfolio that, if applied to the accounts, may
have adversely affected their performance results. The composite total returns
of these discretionary accounts does not represent the historical performance of
the Portfolio and should not be viewed as a prediction of future performance of
the Portfolio. The Index is an unmanaged composite of consisting of
publicly-issued, fixed-rate, non-convertible, domestic bonds that are below
investment grade. The total returns of the Index do not include management fees
or commissions.

MASTER-FEEDER STRUCTURE
 
Unlike other mutual funds that directly acquire and manage their own portfolio
of securities, the Fund seeks to achieve its investment objective by investing
all of its investable assets in the Portfolio, a separate investment company
with the same investment objective as the Fund. The investment objective of the
Fund and the Portfolio may be changed only with the approval of the holders of a
majority of the outstanding voting securities of the Fund or a majority of the
investors in the Portfolio, respectively, after 30 days' prior notice.
 
This master-feeder structure has been developed relatively recently, so
shareholders should carefully consider this investment approach.
 
In addition to selling an interest in the Portfolio to the Fund, the Portfolio
may sell interests in the Portfolio to other mutual funds or institutional
investors. Such investors will invest in the Portfolio on the same terms and
conditions as the Fund and will incur a proportionate share of the Portfolio's
expenses. However, other entities investing in the Portfolio may sell shares of
their own fund using a different pricing structure than the Fund's. Such
different pricing structures may result in differences in returns experienced by
investors in other funds that invest in the Portfolio. Such differences in
returns are not uncommon and are present in other mutual fund structures.
Information concerning other holders of interests in the Portfolio is available
from Investors Bank at (888) UBS-FUND.
 
The Fund may withdraw its investment in the Portfolio at any time if the Board
determines that it is in the Fund's best interest to do so. Upon any such
withdrawal, the Board would consider what action might be taken, including the
investment of all the Fund's assets in another pooled investment entity having
the same investment objective and restrictions as the Fund or the retaining of
an investment adviser to manage the Fund's assets in accordance with the
investment policies described below with respect to the Portfolio.
 
Certain changes in the Portfolio's investment objective, policies or
restrictions, or a failure by the Fund's shareholders to approve a change in the
Portfolio's investment objective or restrictions, may require the Fund to
withdraw its investments in the Portfolio. Any such withdrawal could result in
an in-kind distribution of portfolio securities (as opposed to a cash
distribution) by the Portfolio to the Fund. Such a distribution may result in
the Fund's having a less diversified portfolio of investments or adversely
affect the Fund's liquidity, and the Fund could incur brokerage, tax or other
charges in converting such 
 
                                      -4-
 



<PAGE>
<PAGE>
securities to cash. Notwithstanding the above, there
are other means for meeting shareholder redemption requests, such as borrowing.
 
Smaller funds investing in the Portfolio may be materially affected by the
actions of larger funds investing in the Portfolio. For example, if a large fund
withdraws from the Portfolio, the remaining funds may subsequently experience
higher pro rata operating expenses, thereby lowering returns. Additionally,
because the Portfolio would become smaller, it may become less diversified,
resulting in potentially increased portfolio risk (however, these possibilities
also exist for traditionally structured funds that have large or institutional
investors who may withdraw from a fund). Also, funds with a greater pro rata
ownership in the Portfolio could have effective voting control of its
operations. Except as permitted by the Securities and Exchange Commission (the
'SEC'), whenever the Fund is requested to vote on matters pertaining to the
Portfolio, the Company will hold a meeting of Fund shareholders and will cast
all of its votes proportionately as instructed by the Fund's shareholders. See
'Organization' in the SAI. Fund shareholders who do not vote will not affect the
Fund's votes at the Portfolio meeting. The percentage of the Company's votes
representing Fund shareholders not voting will be voted by the Company in the
same proportion as the Fund shareholders who do, in fact, vote.
 
For more information about the Portfolio's investment objective, policies and
restrictions, see 'Investment Objective and Policies', 'Additional Investment
Information and Risk Factors' and 'Investment Restrictions'. For more
information about the Portfolio's management and expenses, see 'Management'. For
more information about changing the investment objective, policies and
restrictions of the Fund or the Portfolio, see 'Investment Restrictions'.
 
INVESTMENT OBJECTIVES AND POLICIES
 
The investment objectives of the Fund and the Portfolio are described below,
together with the policies each employs to seek to achieve its objective.
Additional information about the investment policies of the Fund and the
Portfolio appears in the SAI under 'Investment Objectives and Policies.' The
Fund seeks to achieve its objectives by investing all of its investable assets
in the Portfolio, which has the same investment objectives as the Fund. There
can be no assurance that the investment objectives of the Fund or the Portfolio
will be achieved.
 
The Adviser is responsible for supervising the management of the Portfolio's
investments. Consistent with these duties, the Adviser has entered into a
Sub-Advisory Agreement with UBSAM (the 'Sub-Adviser' and, together with the
Adviser, the 'Advisers'), whereby the Sub-Adviser is primarily responsible for
the day-to-day investment decisions for the Portfolio. The Adviser is solely
responsible for paying the Sub-Adviser for these services. The Sub-Adviser is an
affiliate of the Adviser.
 
The primary objective of the Portfolio is to provide high current income from a
portfolio of higher-yielding, lower-rated debt securities issued by domestic and
foreign companies. The Portfolio will seek to achieve this investment objective
of high current income by investing, under normal market conditions, at least
65% of its assets in debt securities, convertible securities or preferred stocks
that are consistent with this objective. The Portfolio's remaining
assets may be held in cash or money market instruments, or invested in equity
securities when these types of investments are consistent with high current
income.
 
The Portfolio seeks its secondary objective of capital growth, when consistent
with high current income, by investing in securities, including common stocks
and non-income producing securities, which the Sub-Adviser expects will
appreciate in value as a result of declines in long-term interest rates or
favorable developments affecting the business or prospects of the issuer which
may improve the issuer's financial condition and credit rating. The Portfolio
may invest up to 25% of its assets in the securities of foreign issuers.
 
The Fund is designed for investors who seek current income that is higher than
that generally available from a portfolio of higher-rated obligations while
recognizing the additional risks of lower-rated obligations. The Fund may also
be a convenient way to add high yield bond exposure to diversify an investor's
existing portfolio.
 
Higher yields are generally available from securities in the lower rating
categories of Moody's Investor Services, Inc. ('Moody's') and Standard & Poor's
Ratings Group ('S&P'), including securities rated Baa or  

                                      -5-
 



<PAGE>
<PAGE>

lower by Moody's or BBB or lower by S&P. Securities rated Baa or BBB are
considered investment grade, but have some speculative characteristics.
Securities rated below Baa or BBB are considered to be of poor standing and
predominantly speculative. The Portfolio may invest up to 10% of its assets in
securities rated below Caa by Moody's or CCC by S&P, including securities in the
lowest rating category of either rating agency, or in unrated securities that
the Sub-Adviser determines to be of comparable quality. If, subsequent to the
Portfolio's purchase of a security, the security's rating is reduced by a rating
service, the Portfolio will not necessarily dispose of that security. The
Sub-Adviser will, however, monitor the investment to determine whether continued
investment in the security will assist in meeting the Fund's investment
objective.
 
The Sub-Adviser intends to identify and purchase specific securities that will
constitute a diversified portfolio. In selecting securities, the Sub-Adviser
will use quantitative tools, analyses of credit risk, the expertise of a
dedicated trading desk, and the judgment of fixed income portfolio managers and
analysts. Under normal circumstances, the Sub-Adviser intends to keep at least
65% of the Portfolio's assets invested in bonds. Bonds are debt instruments such
as debentures, notes, mortgage securities, equipment trust certificates and
other collateralized securities, zero coupon securities, government obligations
and money market instruments. See 'Corporate Bonds', 'Foreign Securities' and
'Temporary Defensive Investments' below.
 
As a secondary activity, the Sub-Adviser may also manage the Portfolio's
duration (defined below), and the allocation of securities across market
sectors. Based on fundamental economic and capital markets research, the
Sub-Adviser may adjust the duration of the Portfolio in light of market
conditions and the Sub-Adviser's opinion regarding future interest rates. For
example, if interest rates are expected to fall, the duration may be lengthened
to take advantage of the anticipated increase in bond prices. The Sub-Adviser
also actively allocates the Portfolio's assets among the broad sectors of the
fixed income market including, but not limited to, corporate securities, private
placements, asset-backed securities and mortgage related securities.
 
   
Duration is a measure of a bond's price sensitivity, expressed in years. It is a
measure of interest rate risk of a bond calculated by taking into consideration
the number of years until the average dollar, in present value terms, is
received from principal and interest payments. For example, for a bond with a
duration of four years, every 1% change in yield will result in approximately a
4% change in price in the opposite direction. The Portfolio's benchmark is the
Merrill Lynch All High Yield Bond Index, which currently has a duration of
approximately 4.32 years. The Portfolio intends to have a duration between 3
years and 8 years. The maturities of the Portfolio's individual securities may
vary widely from its duration, however, and may be as long as 30 years.
    

 The Portfolio intends to manage its securities actively in pursuit of its
investment objective. Portfolio transactions are undertaken principally to
accomplish the Portfolio's objective in relation to expected movements in the
general level of interest rates, but the Portfolio may also engage in short-term
trading consistent with its objective. To the extent the Portfolio engages in
short-term trading, it may incur increased transaction costs. See 'Taxes' below.
The annual portfolio turnover rate for the Fund is expected to be under 100%.
 
CORPORATE BONDS. The Portfolio may invest in a broad range of corporate bonds of
domestic and foreign issuers. These include debt securities of various types and
maturities, e.g., debentures, notes, mortgage securities, equipment trust
certificates and other collateralized securities and zero coupon securities.
Collateralized securities are backed by a pool of assets such as loans or
receivables that generate cash flow to cover the payments due on the securities.
Collateralized securities are subject to certain risks, including a decline in
the value of the collateral backing the security, failure of the collateral to
generate the anticipated cash flow or in certain cases more rapid prepayment
than anticipated because of events affecting the collateral, such as accelerated
prepayment of mortgages or other loans backing these securities or destruction
of equipment subject to equipment trust certificates. In the event of any such
prepayment, the Portfolio will be required to reinvest the proceeds of
prepayments at interest rates prevailing at the time of reinvestment, which may
be lower than the interest rates on the prepaid securities. In addition, the
value of zero coupon securities, which do not pay interest, is more volatile
than that of interest bearing debt securities with the same maturity. Although
zero coupon securities do not 
                                      -6-
 



<PAGE>
<PAGE>
pay interest to the holders thereof, federal income tax law requires
the Fund to recognize a portion of such securities' discount as
income each year. This income must be distributed to shareholders
along with other income earned by the Fund. See 'Dividends and Distributions'.
The Portfolio may invest to a limited degree in common stock, convertible debt
or preferred stocks to the extent consistent with the investment objective of
the Portfolio. The Portfolio does not expect to invest more than 25% of its
total assets in securities of foreign issuers. If the Portfolio invests in
non-U.S. dollar denominated securities, it may hedge its foreign currency
exposure. The Portfolio may purchase nonpublicly offered debt securities. See
'Illiquid Investments; Privately Placed and Other Unregistered Securities'. See
'Additional Investment Information and Risk Factors' for further information on
foreign investments and convertible securities.
 
FOREIGN SECURITIES. The Portfolio may invest in securities principally traded in
foreign markets. The Portfolio may also purchase Eurodollar certificates of
deposits without regard to the 25% limit. Since Foreign securities are normally
denominated and traded in foreign currencies, the Portfolio's net asset value
may be affected favorably or unfavorably by currency exchange rates and exchange
control regulations. See 'Foreign Investment Information' and 'Foreign Currency
Exchange Transactions' under 'Additional Investment Information and Risk
Factors'.
 
TEMPORARY DEFENSIVE INVESTMENTS. Under unusual market circumstances, the Fund
may seek to limit the risk of principal loss by reducing its exposure to high
yield bonds in favor of other, more defensive investments. Defensive investments
may include money market instruments, or higher-rated fixed income securities,
including U.S. Government and agency obligations. The yields on these securities
will generally be lower than those on lower-rated securities and the Fund's net
investment income and dividend yield will decrease accordingly. The Fund cannot
predict when, if ever, it might use these defensive investments, to what extent
it might utilize these investments or for how long it might hold these types of
investments.

MONEY MARKET INSTRUMENTS. The Portfolio may also purchase money market
instruments to invest temporary cash balances or to maintain liquidity to meet
withdrawals. However, the Portfolio may also invest, without limit, in money
market instruments as a temporary defensive measure taken during, or in
anticipation of, adverse market conditions. The money market investments
permitted for the Portfolio include obligations of the U.S. Government
 and its agencies and instrumentalities, other debt securities, money market
mutual funds, commercial paper, bank obligations and repurchase agreements. For
more detailed information about these money market investments, see 'Investment
Objectives and Policies' in the SAI.
 
The Portfolio may also purchase obligations on a when-issued or delayed delivery
basis, enter into repurchase and reverse repurchase agreements, loan its
portfolio securities, purchase certain privately placed securities and enter
into certain hedging transactions that may involve options on securities and
securities indices, futures contracts and options on futures contracts. For a
discussion of these investments and investment techniques, see 'Additional
Investment Information and Risk Factors'.
 
ADDITIONAL INVESTMENT INFORMATION AND RISK FACTORS
 
LOWER-RATED SECURITIES. Changes by ratings services in their ratings of
securities held by the Portfolio may affect the value of these investments.
Changes in the value of portfolio investments generally will not affect the
income derived from these investments, but will affect the Fund's net asset
value.
 
Securities rated C by Moody's are the lowest rated class and can be regarded as
having extremely poor prospects of ever attaining any real investment standing.
Debt rated D by S&P, its lowest rating, is in default or is expected to default
upon maturity or payment date.
 
Lower-rated, and unrated securities determined by the Sub-Adviser to be
comparable, (i) will likely have some quality and protective characteristics
that, in the judgment of the rating organization and/or the Sub-Adviser, are
outweighed by considerable uncertainties or major exposures to adverse
conditions and (ii) are predominantly speculative with respect to the issuer's
capacity to pay interest and repay principal in accordance with the terms of the
obligation. The market values of these securities tend to be more 

                                      -7-

<PAGE>

sensitive to individual corporate developments and changes in economic
conditions than higher-quality securities.
 
The inability (or perceived inability) of issuers to make timely payments of
interest and principal would likely make the values of securities held by the
Portfolio more volatile and could limit the Portfolio's ability to sell its
securities at prices approximating the values the Portfolio had placed on these
securities. The absence of a liquid trading market for certain of these
securities may make it more difficult for the Portfolio to establish the fair
market value of these securities and calculate the Fund's net asset value. The
rating assigned to a security by Moody's or S&P does not reflect an assessment
of the volatility of the security's market value or the liquidity of an
investment in the security.
 
For a complete description of the rating systems of Moody's and S&P, see the
Appendix to the SAI.
 
CONVERTIBLE SECURITIES. The convertible securities in which the Portfolio may
invest include any debt securities or preferred stocks that may be converted
into common stock or that carry the right to purchase common stock. Convertible
securities entitle the holder to exchange the securities for a specified number
of shares of common stock, usually of the same company, at specified prices
within a certain period of time.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Portfolio may purchase
securities on a when-issued or delayed delivery basis. Delivery of and payment
for these securities may take as long as a month or more after the date of the
purchase commitment. The value of these securities is subject to market
fluctuation during this period and no interest or income accrues to the
Portfolio until settlement. At the time of settlement, a when-issued security
may be valued at less than its purchase price. Between the trade and settlement
dates, the Portfolio will maintain a segregated account with the Custodian
consisting of a portfolio of liquid securities with a value at least equal to
these commitments. When entering into a when-issued or delayed delivery
transaction, the Portfolio will rely on the other party to consummate the
transaction; if the other party fails to do so, the Portfolio may be
disadvantaged. It is the current policy of the Portfolio not to enter into
when-issued commitments exceeding in the aggregate 15% of the market value of
the Portfolio's total assets less liabilities (excluding the obligations created
by these commitments).
 
REPURCHASE AGREEMENTS. The Portfolio may engage in repurchase agreement
transactions with brokers, dealers or banks that meet the credit guidelines
approved by the Trust's Board of Trustees (the 'Trustees'). In a repurchase
agreement, the Portfolio buys a security from a seller that has agreed to
repurchase it at a mutually agreed upon date and price, reflecting the interest
rate effective for the term of the agreement. The term of these agreements is
usually from overnight to one week. A repurchase agreement may be viewed as a
fully collateralized loan of money by the Portfolio to the seller. The Portfolio
always receives securities as collateral with a market value at least equal to
the purchase price plus accrued interest and this value is maintained during the
term of the agreement. If the seller defaults and the collateral's value
declines, the Portfolio might incur a loss. If bankruptcy proceedings are
commenced with respect to the seller, the Portfolio's realization upon the
disposition of collateral may be delayed or limited. Investments in repurchase
agreements maturing in more than seven days and certain other investments that
may be considered illiquid are limited. See 'Illiquid Investments; Privately
Placed and Other Unregistered Securities' below.
 
REVERSE REPURCHASE AGREEMENTS. The Portfolio is permitted to enter into reverse
repurchase agreements. In a reverse repurchase agreement, the Portfolio sells a
security and agrees to repurchase it at a mutually agreed upon date and price,
reflecting the interest rate effective for the term of the agreement. It may
also be viewed as the borrowing of money by the Portfolio and, therefore, is a
form of leverage. Leverage may cause any gains or losses of the Portfolio to be
magnified. For more information, including limitations on the use of reverse
repurchase agreements, see 'Investment Objectives and Policies' in the SAI.
 
SECURITIES LENDING. Subject to applicable investment restrictions, the Portfolio
may lend its securities. The Portfolio may lend its securities if such loans are
secured continuously by cash or equivalent collateral or by a letter of credit
in favor of the Portfolio at least equal at all times to 100% of the market
value of the securities loaned, plus accrued interest. While such securities are
on loan, the borrower will pay the 

                                      -8-
 



<PAGE>
<PAGE>

Portfolio any income accruing thereon. Loans will be subject to termination
by the Portfolio in the normal settlement time, generally three
business days after notice, or by the borrower on one day's notice.
Borrowed securities must be returned when the loan is terminated. Any
gain or loss in the market price of the borrowed securities that occurs during
the term of the loan inures to the Portfolio and its respective investors. The
Portfolio may pay reasonable finders' and custodial fees in connection with a
loan. In addition, the Portfolio will consider all the facts and circumstances,
including the creditworthiness of the borrowing financial institution, and the
Portfolio will not make any loans in excess of one year. The Portfolio will not
lend its securities to any officer, Trustee, Director, employee or affiliate or
placement agent of the Company, the Portfolio, or the Adviser, Sub-Adviser
Administrator or Distributor, unless otherwise permitted by applicable law.
 
FOREIGN INVESTMENT INFORMATION. Investments in securities of foreign issuers and
in obligations of foreign branches of domestic banks involve somewhat different
investment risks from those affecting securities of domestic issuers. There may
be limited publicly available information with respect to foreign issuers, and
foreign issuers are not generally subject to uniform accounting, auditing and
financial standards and requirements comparable to those applicable to domestic
companies. Dividends and interest paid by foreign issuers may be subject to
withholding and other foreign taxes that may decrease the net return on such
investments.
 
Investors should realize that the value of the Portfolio's investments in
foreign securities may be adversely affected by changes in political or social
conditions, diplomatic relations, confiscatory taxation, expropriation,
nationalization, limitation on the removal of funds or assets, or imposition of
(or change in) exchange control or tax regulations in those foreign
 countries. In addition, changes in government administrations or economic or
monetary policies in the United States or abroad could result in appreciation or
depreciation of portfolio securities and could favorably or unfavorably affect
the Portfolio's operations. Furthermore, the economies of individual foreign
nations may differ from the U.S. economy, favorably or unfavorably, in areas
such as growth of gross national product, rate of inflation, capital
reinvestment, resource self-sufficiency and balance of payments position; it may
also be more difficult to obtain and enforce a judgment against a foreign
issuer. Any foreign investments made by the Portfolio must be made in compliance
with U.S. and foreign currency restrictions and tax laws restricting the amounts
and types of foreign investments.
 
In addition, while the volume of transactions effected on foreign securities
exchanges has increased in recent years, in most cases it remains appreciably
below that of domestic security exchanges. Accordingly, the Portfolio's foreign
investments may be less liquid and their prices may be more volatile than
comparable investments in securities of U.S. companies. Moreover, the settlement
periods for foreign securities, which are often longer than those for securities
of U.S. issuers, may affect portfolio liquidity. In buying and selling
securities on foreign exchanges, purchasers normally pay fixed commissions that
are generally higher than the negotiated commissions charged in the United
States. In addition, there is generally less government supervision and
regulation of securities exchanges, brokers and issuers located in countries
other than in the United States.
 
The Portfolio may invest in securities of foreign issuers directly or in the
form of American Depository Receipts ('ADRs'), European Depository Receipts
('EDRs'), Global Depository Receipts ('GDRs') or other similar securities of
foreign issuers. These securities may not necessarily be denominated in the same
currency as the securities they represent. ADRs are receipts typically issued by
a U.S. bank or trust company evidencing ownership of the underlying foreign
securities. Certain institutions issuing ADRs may not be sponsored by the issuer
of the underlying foreign securities. A non-sponsored depository may not provide
the same shareholder information that a sponsored depository is required to
provide under its contractual arrangements with the foreign issuer. EDRs are
receipts issued by a European financial institution evidencing a similar
arrangement. GDRs are issued outside the United States, typically by non-U.S.
banks and trust companies. Generally, ADRs, in registered form, are designed for
use in the U.S. securities markets, and EDRs and GDRs, in bearer form, are
designed for use in European securities markets, and domestic and European
securities markets, respectively.
 
Because investments in foreign securities involve foreign currencies, the value
of assets as measured in U.S. dollars may be affected, favorably or unfavorably,
by changes in currency exchange rates and in 
                                      -9-
 



<PAGE>
<PAGE>
exchange control regulations, including currency blockage. See 'Foreign
Currency Exchange Transactions' below.
 
FOREIGN CURRENCY EXCHANGE TRANSACTIONS. Because the Portfolio may buy and sell
securities and receive interest and dividends in currencies other than the U.S.
dollar, the Portfolio may, from time-to-time, enter into foreign currency
exchange transactions. The Portfolio may enter into these transactions on a spot
(i.e., cash) basis at the spot rate prevailing in the foreign currency exchange
market, use forward currency contracts to purchase or sell foreign currencies,
use currency futures contracts or purchase or sell options thereon or purchase
or sell currency options.
 
A forward foreign currency exchange contract is an obligation of the Portfolio
to purchase or sell a specific currency at a future date, which may be any fixed
number of days from the date of the contract. Currency options give the buyer
the right, but not the obligation, to purchase or sell a fixed amount of a
specific currency at a fixed price at a future date. These contracts are entered
into in the interbank market directly between currency traders (usually large
commercial banks) and their customers. A forward foreign currency exchange
contract generally has no deposit requirement, and is traded at a net price
without commission. The Portfolio will not enter into these foreign currency
exchange transactions for speculative purposes. Foreign currency
exchange transactions do not eliminate fluctuations in the local currency
prices of the Portfolio's securities or in foreign exchange rates, or prevent
loss if the local currency prices of these securities should decline.
 
A currency futures contract is a contract involving an obligation to deliver or
acquire the specified amount of a currency at a specified price at a specified
future time. Futures contracts may be settled on a net cash payment basis rather
than by the sale and delivery of the underlying currency.
 
The Portfolio may enter into foreign currency exchange transactions in an
attempt to protect against changes in foreign currency exchange rates between
the trade and settlement dates of specific securities transactions or
anticipated securities transactions. The Portfolio may use these techniques to
hedge against a change in foreign currency exchange rates (with the U.S. dollar
or other foreign currencies) that would cause a decline in the value of existing
investments denominated or principally traded in a foreign currency.
 
Although these transactions are intended to minimize the risk of loss due to a
decline in the value of the hedged currency, these transactions also limit any
potential gain that might be realized should the value of the hedged currency
increase. Additionally, the premiums paid by the Portfolio for currency or
futures options increase the Portfolio's transaction costs. Similarly, the cost
of the Portfolio's spot currency exchange transactions is generally the
difference between the bid and offer spot rate of the currency being purchased
or sold. The precise matching of these transactions and the value of the
securities involved will not generally be possible because the future value of
such securities in foreign currencies will change as a consequence of market
movements in the value of such securities between the date such a transaction is
entered into and the date it matures. The projection of currency market
movements is extremely difficult and the successful execution of a hedging
strategy is highly uncertain.
 
ILLIQUID INVESTMENTS; PRIVATELY PLACED AND OTHER UNREGISTERED SECURITIES. The
Portfolio may not acquire any illiquid securities if, as a result thereof, more
than 15% of the market value of the Portfolio's net assets would be in illiquid
investments or investments that are not readily marketable. In addition, the
Portfolio will not invest more than 10% of the market value of its total assets
in restricted securities (not including Rule 144A securities) that cannot be
offered for public sale in the United States without first being registered
under the Securities Act of 1933, as amended (the 'Securities Act'). Subject to
those non-fundamental policy limitations, the Portfolio may acquire investments
that are illiquid or have limited liquidity, such as private placements or
investments that are not registered under the Securities Act, and cannot be
offered for public sale in the United States without first being registered. An
illiquid investment is any investment that cannot be disposed of within seven
days in the normal course of business at approximately the amount at which it is
valued by the Portfolio. Repurchase agreements maturing in more than seven days
are considered illiquid investments and, as such, are subject to the limitations
set forth in this paragraph. The price the Portfolio pays for illiquid
securities or receives upon resale may be lower than the price paid or received
for similar securities with a more liquid market. Accordingly, the valuation of
these securities will reflect any limitations on their liquidity.
 
                                      -10-
 



<PAGE>
<PAGE>
 
The Portfolio may also purchase Rule 144A securities sold to institutional
investors without registration under the Securities Act. These securities may be
determined to be liquid in accordance with guidelines established by the Adviser
and approved by the Trustees of the Trust. The Trustees of the Trust will
monitor the Adviser's implementation of these guidelines on a periodic basis.
 
FUTURES AND OPTIONS TRANSACTIONS. The Portfolio is permitted to enter into the
futures and options transactions described below. These instruments are commonly
known as derivatives.

The Portfolio may purchase and sell exchange traded and over-the-counter ('OTC')
put and call options on fixed income securities or indices of fixed income
securities, enter into forward contracts, purchase and sell futures contracts on
indices of fixed income securities, purchase and sell put and call options on
futures contracts on indices of fixed income securities and purchase and sell
options on currencies. The Portfolio may use these techniques for hedging or
risk management purposes or, subject to certain limitations, for investment
purposes in lieu of investing directly in the corresponding securities or
instruments. Such use of derivatives may be considered speculative.
 
The Portfolio may use these techniques to manage its exposure to changing
interest rates, currency exchange rates and/or security prices. Some options and
futures strategies, including selling futures contracts and buying puts, tend to
hedge the Portfolio's investments against price fluctuations. Other strategies,
including buying futures contracts, writing puts and calls, and buying calls,
may tend to increase market exposure. For example, if the Portfolio wishes to
obtain exposure to a particular market or market sector but does not wish to
purchase the relevant securities, it could, as an alternative, purchase a
futures contract on an index of such securities or related securities. Such a
purchase would not constitute a hedging transaction and could be considered
speculative. However, the Portfolio will use futures contracts or options in
this manner only for the purpose of obtaining the same level of exposure to a
particular market or market sector that it could have obtained by purchasing the
relevant securities and will not use futures contracts or options to leverage
its exposure beyond this level. The use of options and futures may involve some
leverage; such leverage is reduced by the requirement of the SEC to 'cover' such
obligations. See 'Cover -- Segregated Accounts' below. Options and futures
contracts may be combined with each other or with forward contracts in order to
adjust the risk and return characteristics of the Portfolio's overall strategy
in a manner deemed appropriate to the Adviser and consistent with the
Portfolio's objective and policies. Because combined positions involve multiple
trades, they result in higher transaction costs and may be more difficult to
open and close out.
 
The Portfolio's use of these transactions is a highly specialized activity,
which involves investment strategies and risks different from those associated
with ordinary portfolio securities transactions, and there can be no guarantee
that their use will increase the Portfolio's return. While the Portfolio's use
of these instruments may reduce certain risks associated with owning its
portfolio securities, these techniques themselves entail certain other risks. If
the Adviser applies a strategy at an inappropriate time or judges market
conditions or trends incorrectly, such strategies may lower the Portfolio's
return. Certain strategies limit the Portfolio's opportunity to realize gains as
well as limiting its exposure to losses. The Portfolio could experience losses
if the prices of its options and futures positions were poorly correlated with
its other investments, or if it could not close out its positions because of an
illiquid secondary market. In addition, the Portfolio will incur costs,
including commissions and premiums, in connection with these transactions and
these transactions could significantly increase the Portfolio's turnover rate.
 
The Portfolio may purchase and sell put and call options on securities,
currencies, indices of securities and futures contracts, or purchase and sell
futures contracts for the purposes described herein.
 
In addition, in order to assure that the Portfolio will not be considered a
'commodity pool' for purposes of CFTC rules, the Portfolio will enter into
transactions in futures contracts or options on futures contracts only if (1)
such transactions constitute bona fide hedging transactions, as defined under
CFTC rules, or (2) no more than 5% of the Portfolio's net assets are committed
as initial margin or premiums to positions that do not constitute bona fide
hedging transactions.

OPTIONS
 
PURCHASING PUT AND CALL OPTIONS. By purchasing a put option, the Portfolio
obtains the right (but not the obligation) to sell the instrument underlying the
option at a fixed strike price. In return for this right, the Portfolio pays the
current market price for the option (known as the option premium). Options have
various types of underlying instruments, including specific securities,
currencies, indices of securities, indices of securities prices and futures
contracts. The Portfolio may terminate its position in a put option it has
purchased by allowing it to expire or by exercising the option. The Portfolio
may also close out a put option position by entering into an offsetting
transaction, if a liquid market exists. If the option is allowed to expire, the
Portfolio will lose the entire premium it paid. If the Portfolio exercises a put
option on a security, it will sell the instrument underlying the option at the
strike price. If the Portfolio exercises an option on an index, settlement is in
cash and does not involve the actual sale of securities. American style options
may be exercised on any day up to their expiration date. European style options
may be exercised only on their expiration date.
 
The buyer of a typical put option can expect to realize a gain if the price of
the underlying instrument falls substantially. However, if the price of the
instrument underlying the option does not fall enough to offset the cost of
purchasing the option, a put buyer can expect to suffer a loss (limited to the
amount of the premium paid, plus related transaction costs).
 
The features of call options are essentially the same as those of put options,
except that the purchaser of a call option obtains the right to purchase, rather
than sell, the instrument underlying the option at the option's strike price. A
call buyer typically attempts to participate in potential price increases of the
instrument underlying the option with risk limited to the cost of the option and
related transaction costs if security prices fall. At the same time, the buyer
can expect to suffer a loss if security prices do not rise sufficiently to
offset the cost of the option.
 
SELLING (WRITING) PUT AND CALL OPTIONS. When the Portfolio writes a put option,
it takes the opposite side of the transaction from the option's purchaser. In
return for receipt of the premium, the Portfolio assumes the obligation to pay
the strike price for the instrument underlying the option if the other party to
the option chooses to exercise it. The Portfolio may seek to terminate its
position in a put option it writes before exercise by purchasing an offsetting
option in the market at its current price. If the market is not liquid for a put
option the Portfolio has written, however, the Portfolio must continue to be
prepared to pay the strike price while the option is outstanding, regardless of
price changes, and must continue to post margin as discussed below.
 
If the price of the underlying instrument rises, a put writer would generally
expect to profit, although its gain would be limited to the amount of the
premium it received. If security prices remain the same over time, it is likely
that the writer will also profit, because it should be able to close out the
option at a lower price. If security prices fall, however, the put writer would
expect to suffer a loss. This loss should be less than the loss from purchasing
and holding the underlying instrument directly, however, because the premium
received for writing the option should offset a portion of the decline.
 
Writing a call option obligates the Portfolio to sell or deliver the option's
underlying instrument in return for the strike price upon exercise of the
option. The characteristics of writing call options are similar to those of
writing put options, except that writing calls generally is a profitable
strategy if prices remain the same or fall. Through receipt of the option
premium a call writer offsets part of the effect of a price decrease. At the
same time, because a call writer must be prepared to deliver the underlying
instrument in return for the strike price, even if its current value is greater,
a call writer gives up some ability to participate in security price increases.
 
The writer of a U.S. exchange traded put or call option on a security, an index
of securities or a futures contract is required to deposit cash or securities or
a letter of credit as margin and to make mark-to-market payments of variation
margin if and as the position becomes unprofitable.
 
OPTIONS ON INDICES. The Portfolio is permitted to enter into options
transactions and may purchase and sell put and call options on any securities
index based on securities in which the Portfolio may invest. Options on
securities indices are similar to options on securities, except that the
exercise of securities index options is settled by cash payment and does not
involve the actual purchase or sale of securities. In
 
                                      -12-
 



<PAGE>
<PAGE>
addition, these options are designed to reflect price fluctuations in a group
of securities or segment of the securities market rather than price fluctuations
in a single security. The Portfolio, in purchasing or selling index options, is
subject to the risk that the value of its portfolio securities may not change
as much as an index because the Portfolio's investments generally will not match
the composition of an index.
 
For a number of reasons, a liquid market may not exist and thus the Portfolio
may not be able to close out an option position that it has previously entered
into. When the Portfolio purchases an OTC option, it will be relying on its
counterparty to perform its obligations, and the Portfolio may incur additional
losses if the counterparty is unable to perform.
 
FUTURES CONTRACTS
 
When the Portfolio purchases a futures contract, it agrees to purchase a
specified quantity of an underlying instrument at a specified future date and
price or to make or receive a cash payment based on the value of a securities
index. When the Portfolio sells a futures contract, it agrees to sell a
specified quantity of the underlying instrument at a specified future date and
price or to receive or make a cash payment based on the value of a securities
index. The price at which the purchase and sale will take place is fixed when
the Portfolio enters into the contract. Futures can be held until their delivery
dates or the positions can be (and normally are) closed out before then. There
is no assurance, however, that a liquid market will exist when a Portfolio
wishes to close out a particular position.
 
When the Portfolio purchases or sells a futures contract, the value of the
futures contract tends to increase and decrease in tandem with the value of its
underlying instrument. Purchasing futures contracts may tend to increase the
Portfolio's exposure to positive and negative price fluctuations in the
underlying instrument, much as if it had purchased the underlying instrument
directly, as discussed above. When the Portfolio sells a futures contract, by
contrast, the value of its futures position will tend to move in a direction
contrary to the value of the underlying instrument. Selling futures contracts on
securities similar to those held by the Portfolio, therefore, will tend to
offset both positive and negative market price changes, much as if the
underlying instrument had been sold. Because there are a limited number of types
of exchange-traded options and futures contracts, it is likely that these
standardized instruments will not exactly match the Portfolio's current or
anticipated investments. The Portfolio may invest in futures contracts and
options thereon based on currencies or on securities with different issuers,
maturities, or other characteristics from the securities in which it typically
invests, which involves a risk that the options or futures position will not
track the performance of the Portfolio's other investments. The Portfolio may
also enter into transactions in futures contracts and options for non-hedging
purposes, as discussed above.
 
The purchaser or seller of a futures contract is not required to deliver or pay
for the underlying instrument unless the contract is held until the delivery
date. However, when the Portfolio buys or sells a futures contract it will be
required to deposit 'initial margin' either with the Custodian in a segregated
account in the name of its futures broker, known as a futures commission
merchant ('FCM'), or with the FCM. Initial margin deposits are typically equal
to a small percentage of the contract's value. If the value of either party's
position declines, that party will be required to make additional 'variation
margin' payments equal to the change in value on a daily basis. The party that
has a gain may be entitled to receive all or a portion of this amount. The
Portfolio may be obligated to make payments of variation margin
at a time when it is disadvantageous to do so. Furthermore, it may not
always be possible for the Portfolio to close out its futures positions.
Until it closes out a futures position, the Portfolio will be obligated to
continue to pay variation margin. Initial and variation margin payments do not
constitute purchasing on margin for purposes of the Portfolio's investment
restrictions. In the event of the bankruptcy of an FCM that holds margin on
behalf of the Portfolio, the Portfolio may be entitled to return of margin owed
to it only in proportion to the amount received by the FCM's other customers,
potentially resulting in losses to the Portfolio.
 
COVER -- SEGREGATED ACCOUNTS. The Portfolio will segregate liquid securities in
connection with its use of options and futures contracts to the extent required
by the SEC. Securities held in a segregated account cannot be sold while the
futures contract or option is outstanding, unless they are replaced with other
suitable assets. As a result, there is a possibility that the segregation of a
large percentage of the 

 
                                      -13-

Portfolio's assets could impede portfolio management or
the Portfolio's ability to meet redemption requests or other current
obligations.
 
For further information about the Portfolio's use of futures and options and a
more detailed discussion of associated risks, see 'Investment Objectives and
Policies' in the SAI.
 
INVESTMENT RESTRICTIONS
 
The investment objective of the Fund and the Portfolio, together with the
investment restrictions described below and in the SAI, except as noted, are
deemed fundamental policies, i.e., they may be changed only by the 'vote of a
majority of the outstanding voting securities' (as defined in the Investment
Company Act of 1940 (the '1940 Act')), of the Fund or the Portfolio,
respectively. The Fund has the same investment restrictions as the Portfolio,
except that the Fund may invest all of its investable assets in another open-end
investment company with the same investment objective and restrictions (such as
the Portfolio). References below to the Portfolio's investment restrictions also
include the Fund's investment restrictions.
 
As a diversified investment company, 75% of the total assets of the Portfolio
are subject to the following fundamental limitations: (a) the Portfolio may not
invest more than 5% of its total assets in the securities of any one issuer,
except U.S. Government securities; and (b) the Portfolio may not own more than
10% of the outstanding voting securities of any one issuer.
 
The Portfolio may not: (i) purchase the securities or other obligations of
issuers conducting their principal business activity in the same industry if its
investments in such industry would exceed 25% of the value of the Portfolio's
total assets, except this limitation shall not apply to investments in U.S.
Government securities; (ii) enter into reverse repurchase agreements or other
permitted borrowings that constitute senior securities under the 1940 Act,
exceeding in the aggregate one-third of the value of the Portfolio's total
assets; or (iii) borrow money, except from banks for extraordinary or emergency
purposes, or mortgage, pledge or hypothecate any assets except in connection
with any such borrowings or permitted reverse repurchase agreements in amounts
up to one-third of the value of the Portfolio's total assets at the time of such
borrowing, or purchase securities while borrowings and other senior securities
exceed 5% of its total assets. For a more detailed discussion of the above
investment restrictions, as well as a description of certain other investment
restrictions, see 'Investment Restrictions' and 'Additional Information' in the
SAI.
 
MANAGEMENT
 
DIRECTORS AND TRUSTEES. Pursuant to the Trust's Declaration of Trust, the
Trustees of the Trust establish the Portfolio's general policies, are
responsible for the overall management of the Trust, and review the actions of
the Adviser, Sub-Adviser, Administrator and other service providers. Similarly,
the Directors of the Company set the Company's general policies, are
responsible for the overall management of the Company, and review the
performance of its service providers. Additional information about the Company's
Board of Directors and officers appears in the SAI under the heading 'Directors
and Trustees'. The Trustees of the Trust are also the Directors of the Company,
which raises certain conflicts of interest. The Company and the Trust have each
adopted written procedures reasonably designed to deal with these conflicts,
should they arise. The officers of the Company are also employees of Investors
Bank or its affiliates.
 
ADVISER AND FUNDS SERVICES AGENT. The Company has not retained the services of
an investment adviser with respect to the Fund because the Fund seeks to achieve
its investment objective by investing all of its investable assets in the
Portfolio. The Portfolio has retained the services of the New York Branch (the
'Branch' or the 'Adviser') of Union Bank of Switzerland (the 'Bank') as
investment adviser and UBS Asset Management (New York) Inc. ('UBSAM') as
investment sub-adviser (the 'Sub-Adviser' and, together with the Branch, the
'Advisers'). The Branch, which operates out of offices located at 1345 Avenue of
the Americas, New York, New York, is licensed by the Superintendent of Banks of
the State of New York under the banking laws of the State of New York and is
subject to state and federal banking laws and regulations applicable to a
foreign bank that operates a state licensed branch in the United

States. UBSAM, which also operates out of offices located at 1345 Avenue
of the Americas, New York, New York, is a registered investment adviser in
the U.S.
 
   
The Bank has branches, agencies, representative offices and subsidiaries in
Switzerland and in more than 40 cities outside Switzerland, including, in the
United States, New York City, Houston, Los Angeles and San Francisco. In
addition to the receipt of deposits and the making of loans and advances, the
Bank through its offices and subsidiaries engages in a wide range of banking and
financial activities typical of the world's major international banks, including
fiduciary, investment advisory and custodial services and foreign exchange in
the United States, Swiss, Asian and Euro-capital markets. The Bank is one of the
world's leading asset managers and has been active in New York City since 1946.
At June 30, 1997, the Bank (including its consolidated subsidiaries) had total
assets of $352.1 billion (unaudited) and equity capital and reserves of $16.2
billion (unaudited).
    
 
The Advisers provide investment advice and portfolio management to the
Portfolio. Subject to the supervision of the Trustees and the Adviser, the
Sub-Adviser makes the Portfolio's day-to-day investment decisions, arranges for
the execution of portfolio transactions and generally manages the Portfolio's
investments and operations. See 'Investment Adviser' in the SAI.
 
In addition to the above-listed investment advisory services, the Branch also
provides the Fund and the Portfolio with certain related administrative
services. Subject to the supervision of the Directors and Trustees,
respectively, the Branch is responsible for: establishing performance standards
for the third-party service providers of the Fund and Portfolio and overseeing
and evaluating the performance of such entities; providing and presenting
quarterly management reports to the Directors and the Trustees; supervising the
preparation of reports for Fund and Portfolio shareholders; and establishing
voluntary expense limitations for the Fund and providing any resultant expense
reimbursement to the Fund.
 
The Branch provides its administrative services to the Fund pursuant to a Funds
Services Agreement between the Branch and the Company. The Branch does not
receive a fee from the Company or the Fund pursuant to the terms of the Funds
Services Agreement.
 
Under the Trust's Investment Advisory Agreement, the Portfolio pays the Adviser
a fee, calculated daily and payable monthly, equal, on an annual basis, to 0.45%
of the Portfolio's average daily net assets. The Branch has voluntarily agreed
to waive its fees and reimburse the Fund for any of its direct and indirect
expenses to the extent that the Fund's total operating expenses (including its
share of the Portfolio's expenses) exceed, on an annual basis, 0.90% of the
Fund's average daily net assets. The Branch may modify or discontinue
this fee waiver and expense limitation at any time in the future with 30 days'
prior notice to the Fund. See 'Expenses'.

   
SUB-ADVISER. The Sub-Adviser uses a sophisticated, disciplined, collaborative
process for managing the Portfolio. Kevin J. McCormick and Kurtis W. Krestinski
are primarily responsible for the day-to-day management and implementation of
the Sub-Adviser's process for the Portfolio. Mr. McCormick has 12 years
investment experience. Mr. McCormick spent two years as a portfolio manager for
the Sub-Adviser before leaving and joining Wasserstein Perella Securities where
he spent one year. Mr. McCormick rejoined the Sub-Adviser in 1997 as a Director
and Senior Portfolio Manager. He also serves on the firm's Credit Committee. Mr.
McCormick has been affiliated with a number of investment firms, including
Kidder, Peabody & Co., Drexel Burnham Lambert and Citicorp Investment Bank. He
received a BS from the State University of New York at Albany. Mr. Krestinski
has 4 years investment experience and has been an Assistant Vice President and
Portfolio Manager of the Sub-Adviser since 1996. He also serves on the firm's
Credit Committee. Previously, Mr. Krestinski was affiliated with Standard &
Poors and Mercantile and General Reinsurance. He received an MBA from Columbia
Business School and a BBA from Ryerson Polytechnic University. The Sub-Adviser
has advised mutual funds for only a short time.
    
 
   
Pursuant to the Sub-Advisory Agreement between the Adviser and the Sub-Adviser,
the Adviser has agreed to pay the Sub-Adviser a fee, calculated daily and
payable monthly equal, on an annual basis, to 0.25% of the first $25 
    
 
                                      -15-

million of the Portfolio's average daily net assets plus 0.20% of the next $25
million of such assets plus 0.15% on such assets in excess of $50 million. The
Adviser is solely responsible for paying the Sub-Adviser this fee.
    
 
INVESTMENTS IN THE FUND ARE NOT DEPOSITS WITH OR OBLIGATIONS OF, OR GUARANTEED
OR ENDORSED BY, THE BRANCH OR ANY OTHER BANK.
 
ADMINISTRATORS. The Fund and the Portfolio employ Investors Bank & Trust Company
('Investors Bank') and Investors Fund Services (Ireland) Limited ('IBT
Ireland'), a subsidiary of Investors Bank, respectively, as Administrators under

administrative services. The services provided by Investors Bank and IBT Ireland
under the Administration Agreements include certain accounting, clerical and
bookkeeping services, Blue Sky (for the Fund only), corporate secretarial
services and assistance in the preparation and filing of tax returns and reports
to shareholders and the Securities and Exchange Commission ('SEC'). Investors
Bank is a wholly-owned subsidiary of Investors Financial Services Corp., a
publicly-held corporation and holding company registered under the Bank Holding
Company Act of 1956.
 
For its services under the Administration Agreement, the Fund has agreed to pay
Investors Bank a fee, calculated daily and payable monthly, equal, on an annual
basis, to 0.065% of the Fund's first $100 million average daily net assets and
0.025% of the next $100 million average daily net assets. Investors Bank does
not receive a fee from the Fund on average daily net assets in excess of $200
million.
 
For its services under the Administration Agreement, the Portfolio has agreed to
pay IBT Ireland a fee, calculated daily and payable monthly, equal, on an annual
basis, to 0.07% of the Portfolio's first $100 million of average daily net
assets and 0.05% of average daily net assets in excess of $100 million. IBT
Ireland's principal offices are located at Deloitte & Touche House, 29 Earlsfort
Terrace, Dublin 2, Ireland. Investors Bank's principal offices are located at

DISTRIBUTOR. Pursuant to a Distribution Agreement, First Fund Distributors, Inc.
(the 'Distributor') serves as the distributor of Fund shares. The Distributor is
a broker-dealer registered with the SEC and is a member of the National
Association of Securities Dealers, Inc. ('NASD'). The Distributor is authorized
by the NASD to act as a mutual fund underwriter and distributor. The principal
offices of the Distributor are located at 4455 E. Camelback Road, Phoenix, 
Arizona 85018. The Distributor does not receive a fee pursuant to the terms
of the Distribution Agreement, but receives compensation from Investors Bank.

Fund and transfer and dividend disbursing agent for the Fund. See 'Custodian' in
the SAI. The Custodian also maintains offices at 1 First Canadian Place, Suite

SHAREHOLDER SERVICES
 
The Company has entered into a shareholder servicing agreement with the Branch,
and may enter into additional shareholder servicing agreements with one or more
financial institutions (together with the Branch, 'Eligible Institutions') such
as a federal or state-chartered bank, trust company, savings and loan
association or savings bank, or broker-dealer. Pursuant to each shareholder
servicing agreement, an Eligible Institution, as agent for its customers who are
purchasing shares of the Fund, will perform the following services for these
investors, among other things: coordinating shareholder accounts and records,
assisting investors seeking to purchase or redeem Fund shares, providing
performance information relating to the Fund, and responding to shareholder
inquiries. The Company has agreed to pay each Eligible Institution a fee for
these services equal, on an annual basis, to 0.25% of the average daily net
assets of the Fund represented by shares of the Fund owned during the period for
which payment is being made by customers of the Eligible Institution. Under the
terms of the shareholder servicing agreements, Eligible Institutions may
delegate one or more of their responsibilities to other entities at their
expense.
 
EXPENSES
 
In addition to the fees of the Branch, Investors Bank and IBT Ireland, the Fund
will be responsible for other expenses, including brokerage costs and litigation
and extraordinary expenses. The Branch has also voluntarily agreed to limit the
total operating expenses of the Fund, excluding extraordinary expenses, to  

                                      -16-
 



<PAGE>
<PAGE>

an annual rate of 0.90% of the Fund's average daily net assets. The Branch may
modify or discontinue this voluntary expense limitation at any time in the
future with 30 days' prior notice to the Fund.
 
The Fund and the Portfolio may allocate brokerage transactions to their
affiliates and the Adviser's affiliates only if the commissions received by such
affiliates are fair and reasonable when compared to the commissions paid to
unaffiliated brokers in connection with comparable transactions. See 'Portfolio
Transactions' in the SAI.
 
PURCHASE OF SHARES
 
GENERAL INFORMATION ON PURCHASES. Investors may purchase Fund shares only
through the Distributor. All purchase orders must be accepted by the
Distributor. The Fund also reserves the right to determine the purchase orders
that it will accept and reserves the right to cease offering its shares for a
period of time. The shares of the Fund may be purchased only in those states
where they may be lawfully sold.
 
The minimum initial investment in the Fund is $25,000, except that the minimum
initial investment is $10,000 for shareholders of another series of the Company.
The minimum subsequent investment in the Fund for all investors is $5,000. The
minimum initial investment for employees of the Bank or its affiliates is $5,000

requirements may be waived at the Fund's sole discretion.
 
No share certificates will be issued.
 
PURCHASE PRICE AND SETTLEMENT. The shares of the Fund are sold on a continuous
basis without a sales charge at the net asset value per share next determined
after receipt and acceptance of a purchase order by the Distributor. The Fund
calculates its net asset value at the close of business on any day on which
the New York Stock Exchange (the 'NYSE') is open for regular trading
(a 'Fund Business Day'). Purchase orders received and accepted by the
Distributor prior to 4:00 p.m. New York time on any Fund Business Day will be
effective and is executed at the net asset value determined that day. The
purchaser becomes a holder of record that day, provided the Fund receives
payment for those shares on the following business day ('settlement date') and
as a recordholder is entitled to earn dividends. Purchase orders received after
4:00 p.m. will receive the net asset value determined on the next Fund
Business Day, and the investor becomes a holder of record on the business day
following the Fund's receipt of payment. Investors will receive the number of
full and fractional shares of the Fund equal to the dollar amount of their
subscription divided by the net asset value per share of the Fund next
determined on the day that the investor's purchase is accepted. See also
'Purchase of Shares' in the Statement of Additional Information.
 
Customers of Eligible Institutions should request a representative of their
Eligible Institution to assist them in placing a purchase order with the
Distributor. Shareholders who do not currently maintain a relationship with an
Eligible Institution may purchase shares of the Fund directly from the
Distributor by wire transfer or mail.
 
By wire transfer: Purchases may be made by federal funds wire. To place a
purchase order with the Fund, the shareholder must telephone the Transfer Agent
at (888) UBS-FUND (888-827-3863). A completed account application must promptly
follow any wire order for an initial purchase. Completed account applications
should be mailed or sent via facsimile. Investors should contact the Transfer
Agent for further instructions regarding account applications. Account
applications are not required for subsequent purchases; however, the investor's
account number must be clearly indicated on the wire to ensure proper credit.
 
All investments must be paid for by U.S. Federal Funds wire. An investor should
instruct its bank to wire federal funds as indicated below on settlement date:

REDEMPTION OF SHARES
 
GENERAL INFORMATION ON REDEMPTIONS. A shareholder may redeem all or any number
of the shares registered in its name at any time at the net asset value next
determined after a redemption request in proper form is received by the
Distributor. To be in proper form, the Fund must have received the shareholders
taxpayer identification number and address. Redemption requests must include
the name of the Fund, the dollar amount or number of shares to be redeemed and
the shareholder's account number. The request must be signed by a person who is
authorized to transact on behalf of the shareholder. In all cases, all
signatures on a redemption request must be signature guaranteed by an eligible
guarantor institution which includes a domestic bank, a domestic savings and
loan institution, a domestic credit union, a member bank of the Federal
Reserve System or a member firm of a national securities exchange, pursuant to
the Fund's standards and procedures. If the guarantor institution belongs to
one of the Medallion Signature programs, it must use the specific 'Medallion
Guaranteed' stamp. Guarantees by notaries public are not acceptable. Further
documentation, such as copies of corporate resolutions and instruments of
authority may be requested from corporations, administrators, executors,
personal representatives, trustees or custodians to evidence the authority
of the person or entity making the redemption request.
 
Customers of Eligible Institutions must request a representative of their
Eligible Institution to assist them in placing a redemption order with the Fund.

REDEMPTION PRICE AND SETTLEMENT. Redemption orders received by the Distributor
in good form prior to 4:00 p.m. New York time on any Fund Business Day will be
effected and executed at the net asset value determined on that day. Redemption
orders received after 4:00 p.m. New York time will be effected and executed at
the net asset value determined on the next Fund Business Day. Proceeds from the
redemption will be generally deposited the next business day in immediately
available funds to the account designated by the redeeming shareholder, or sent
by check to the address of record if requested by the shareholder.

Shareholders will continue to earn dividends through the day of redemption.
 
Shareholders who maintain an account directly with the Distributor may redeem
Fund shares by mail or telephone.
 
By mail: Redemption requests may be mailed to the Transfer Agent, identifying
the Fund, the dollar amount or number of shares to be redeemed and the
shareholder's account number. The request must be signed in exactly the same
manner as the account is registered (e.g., if there is more than one owner of
the shares, all must sign). In all cases, a signature guarantee is required. See
'General Information on Redemptions' above.
 
By telephone: The shareholder may place a redemption request by calling the
Transfer Agent at 888-UBS-FUND (888-827-3863). Shareholders utilizing the
telephone redemption option must have previously designated this option on the
initial account application, or by subsequent written authorization to the Fund.
Such shareholders risk possible loss of principal and income in the event of a
telephone redemption not authorized by them. The Fund and the Transfer Agent
will employ reasonable procedures to verify  
 
                                      -18-
 


<PAGE>
<PAGE>

that telephone redemption instructions are genuine and will require
that shareholders electing such an option provide a form of personal
identification. The failure by the Fund or the Transfer Agent to employ
such procedures may cause the Fund or the Transfer Agent to be liable for
any losses incurred by investors due to telephone redemptions based upon
unauthorized or fraudulent instructions. The telephone redemption option may
be modified or discontinued at any time upon 60 days' notice to shareholders.
 
MANDATORY REDEMPTION. If the value of a shareholder's holdings in the Fund falls
below $10,000 because of a redemption of shares, the shareholder's remaining
shares may be redeemed 60 days after written notice unless the account is
increased to $10,000 or more. For example, a shareholder whose initial and only
investment is $10,000 may be subject to mandatory redemption resulting from any
redemption that causes his or her investment to fall below $10,000.
 
FURTHER REDEMPTION INFORMATION. Investors should be aware that redemptions may
not be processed unless the redemption request is submitted in proper form. To
be in proper form, the Fund must have received the shareholder's taxpayer
identification number and address. As discussed under 'Taxes' below, the Fund
may be required to impose 'back-up' withholding of federal income tax on
dividends, distributions and redemptions when non-corporate investors have not
provided a certified taxpayer identification number. In addition, if an
investor sends a check to the Distributor for the purchase of Fund shares and
shares are purchased with funds made available by the Distributor before the
check has cleared, the transmittal of redemption proceeds from the sale of those
shares will not occur until the check used to purchase such shares has cleared,
which may take up to 15 days. Redemption delays may be avoided by purchasing
shares by federal funds wire.
 
The right of redemption may be suspended or the date of payment postponed for
such periods as the 1940 Act or the SEC may permit. See 'Redemption of Shares'
in the SAI.
 
EXCHANGE OF SHARES
 
An investor may exchange Fund shares for shares of any other series of the
Company without charge. An exchange may be made so long as after the exchange
the investor has shares, in each series in which it remains an investor, with a
value equal to or greater than each such series' minimum investment amount. See
'Purchase of Shares' in the prospectuses of the other Company series for the
minimum investment amounts for each of those funds. Shares are exchanged on the
basis of relative net asset value per share. Exchanges are in effect redemptions
from one fund and purchases of another fund and the usual purchase and
redemption procedures and requirements are applicable to exchanges. See
appropriate section relating to the purchase and redemption of shares in this
and other prospectuses. See also 'Additional Information' below for an
explanation of the telephone exchange policy.
 
Shareholders subject to federal income tax who exchange shares in one fund for
shares in another fund may recognize capital gain or loss for federal income tax
purposes. The Fund reserves the right to discontinue, alter or limit its
exchange privilege at any time. For investors in certain states, state
securities laws may restrict the availability of the exchange privilege.
 
RETIREMENT PLANS
 
The Fund has available a form of Individual Retirement Account ('IRA') for
investment in Fund shares. Subject to certain restrictions imposed by applicable
tax laws, self-employed individuals may purchase shares of the Fund through
tax-deductible contributions to existing retirement plans known as Self-Employed
Retirement Plans ('SERPs'). Fund shares may also be a suitable investment for
'401(k) Plans' which subject to certain restrictions allow their participants to
invest in qualified pension plans on a tax-deferred basis. The Fund does not
currently act as sponsor to such plans.
 
The minimum initial investment for all such retirement plans is $2,000. The
minimum for all subsequent investments is $500.
 
Under the Internal Revenue Code of 1986, as amended (the 'Tax Code'),
individuals may make IRA contributions of up to $2,000 annually, which may be,
depending on the contributor's participation in an employer-sponsored plan and
income level, wholly or partly tax-deductible. However, dividends and
distributions held in the account are not taxed until withdrawn in accordance
with the provisions of the Tax Code. An individual with a non-working spouse may
establish a separate IRA for the spouse under 

                                      -19-
 



<PAGE>
<PAGE>

the same conditions and contribute a combined maximum of $4,000 annually to
one or both IRAs provided that no more than $2,000 may be contributed to the
IRA of either spouse.
 
Investors should be aware that they may be subject to penalties or additional
taxes on contributions to or withdrawals from IRAs or other retirement plans
under certain circumstances. Prior to a withdrawal, shareholders may be required
to certify as to their age and awareness of such restrictions in writing.
Clients of Eligible Institutions desiring information concerning investments
through IRAs or other retirement plans should contact their Eligible
Institution. Clients who do not maintain a relationship with an Eligible
Institution may obtain such information by calling the Transfer Agent at
(888) UBS-FUND.
 
DIVIDENDS AND DISTRIBUTIONS
 
The Fund will declare daily, and pay monthly, dividends from its daily net
investment income. The Fund may also declare an additional dividend of net
investment income in a given year to the extent necessary to avoid the
imposition of federal excise taxes on the Fund.
 
Substantially all of the Fund's realized net capital gains, if any, will be
declared and paid on an annual basis, except that an additional capital gains
distribution may be made in a given year to the extent necessary to avoid the
imposition of federal excise taxes on the Fund. Declared dividends and
distributions are payable on the payment date to shareholders of record on the
record date.
 
Dividends and capital gains distributions paid by the Fund are automatically
reinvested in additional Fund shares unless the shareholder has elected, in
writing, to have them paid in cash. Dividends and distributions to be paid in
cash are credited to the account designated by the shareholder or sent by check
to the shareholder's address of record, in accordance with the shareholder's
instructions. The Fund reserves the right to discontinue, alter or limit the
automatic reinvestment privilege at any time.
 
To the extent that shareholders of the Fund elect to receive their dividends in
cash, rather than electing to reinvest such dividends in additional shares, the
cash used to make these distributions must be provided from the Fund's assets,
which may include a partial redemption of the Fund's interest in the Portfolio.
The Portfolio will be required to use its own cash or the proceeds from the
sales of its securities in order to fund its income distributions and
redemptions. Moreover, in the case of zero coupon bonds, the Portfolio generally
will not have received any income from the issuer of such a security.
Consequently, the Portfolio must rely on other sources (e.g., proceeds from the
sale of assets or other income) to meet such distribution requirements. To the
extent the Fund makes such cash distributions, the Fund, and indirectly the
Portfolio, will not be able to invest that cash in income producing securities.
Consequently, the current income of the Fund and the Portfolio may ultimately be
reduced.
 
NET ASSET VALUE
 
The Fund's net asset value per share equals the value of the Fund's total assets
(i.e., the value of its investment in the Portfolio plus its other assets) less
the amount of its liabilities, divided by the number of its outstanding shares,
rounded to the nearest cent. Expenses, including the fees payable to the service
providers of the Fund and the Portfolio, are accrued daily. Securities for which
market quotations are readily available are valued at market value. All other
securities will be valued at 'fair value'. See 'Net Asset Value' in the SAI for
information on the valuation of the Portfolio's assets and liabilities.
 
The Fund computes its net asset value once daily at the close of business on
Monday through Friday, except that the net asset value is not computed for the
Fund on a day in which no orders to purchase or redeem Fund shares have been
received or on any day on which the New York Stock Exchange is closed, including
the following holidays: New Year's Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. On days
when U.S. trading markets close early in observance of these holidays, the Fund
expects to close for purchases and redemptions at the same time.

ORGANIZATION
 
UBS PRIVATE INVESTOR FUNDS, INC.
 
   
UBS Private Investor Funds, Inc., a Maryland corporation incorporated on
November 16, 1995, is an open-end management investment company registered under
the 1940 Act and organized as a series fund. The Company is currently authorized
to issue shares in eight series: The UBS Bond Fund Series; The UBS High Yield
Bond Fund Series; The UBS Tax Exempt Bond Fund Series; The UBS Institutional
International Equity Fund Series; The UBS International Equity Fund Series; The
UBS Large Capital Growth Fund Series; The UBS Small Capital Growth Fund Series;
and The UBS U.S. Equity Fund Series. Each outstanding share of the Company will
have a pro rata interest in the assets of its series, but it will have no
interest in the assets of any other Company series. Only shares of The UBS High
Yield Bond Fund Series are offered through this Prospectus.
    
 
Shareholder inquiries by clients of Eligible Institutions should be directed to
their Eligible Institution, while other shareholders should address their
inquiries to the Transfer Agent.
 
Shareholders of the Fund are entitled to one vote for each share and to the
appropriate fractional vote for each fractional share. There is no cumulative
voting. Shares have no preemptive or conversion rights. Shares are fully paid
and nonassessable when issued by the Company. The Company does not intend to
hold meetings of shareholders annually. The Directors may call meetings of
shareholders for action by shareholder vote as may be required by its Articles
of Incorporation or the 1940 Act. For further organizational information,
including certain shareholder rights, see 'Organization' in the SAI.
 
UBS INVESTOR PORTFOLIOS TRUST
 
UBS Investor Portfolios Trust, a master trust fund formed under New York law,
was organized on February 9, 1996. The Declaration of Trust permits the Trustees
to issue interests divided into one or more subtrusts or series. To date, seven
series have been authorized, of which UBS High Yield Bond Portfolio is one.
 
The Declaration of Trust provides that no Trustee, shareholder, officer,
employee, or agent of the Trust shall be held to any personal liability, nor
shall resort be had to such person's private property for the satisfaction of
any obligation or claim or otherwise in connection with the affairs of the
Portfolio, but that only the Trust property shall be liable.
 
The Declaration of Trust provides that the Fund and other entities investing in
the Portfolio (e.g., other investment companies, insurance company separate
accounts and common and commingled trust funds) will each be liable for all the
obligations of the Portfolio. However, the risk of the Fund's incurring
financial loss on account of such liability is limited to circumstances in which
both inadequate insurance existed and the Portfolio itself was unable to meet
its obligations. Accordingly, the Trustees believe that neither the Fund nor its
shareholders will be adversely affected by reason of the Fund's investment in
the Portfolio.
 
TAXES
 
The Fund intends to qualify as a regulated investment company (a 'RIC') under
Subchapter M of the Tax Code. As a RIC, a Fund (as opposed to its shareholders)
will not be subject to federal income taxes on the net investment income and
capital gains that it distributes to its shareholders, provided that at least
90% of its net investment income and realized net short-term capital gains in
excess of net long-term capital losses for the taxable year is distributed. The
Portfolio intends to qualify as a partnership for federal income tax purposes.
As such, the Portfolio generally should not be subject to tax. The status of the
Fund as a regulated investment company is dependent on, among other things, the
Portfolio's continued qualification as a partnership for federal income tax
purposes.

Distributions of net long-term capital gains in excess of net short-term capital
losses are taxable to Fund shareholders as long-term capital gains regardless of
how long a shareholder has held shares in the Fund and regardless of whether
received in the form of cash or reinvested in additional shares. Distributions
of net investment income and realized net short-term capital gains in excess of
net long-term capital losses
 
                                      -21-
 



<PAGE>
<PAGE>
are taxable as ordinary income to Fund shareholders, whether such distributions
are received in the form of cash or reinvested in additional shares. Annual
statements as to the current federal tax status of distributions will be mailed
to shareholders after the end of the taxable year for the Fund. Distributions
to corporate shareholders of the Fund will not qualify for the
dividends-received deduction because the income of the Fund will not consist
of dividends paid by United States corporations.
 
Any gain or loss realized on the redemption or exchange of Fund shares by a
shareholder who is not a dealer in securities generally will be treated as
long-term capital gain or loss if the shares have been held for more than one
year, and otherwise as short-term capital gain or loss. However, any loss
realized by a shareholder upon the redemption or exchange of shares in the Fund
held for six months or less will be treated as a long-term capital loss to the
extent of any long-term capital gain distributions received by the shareholder
with respect to such shares. In addition, no loss will be allowed on the sale or
other disposition of shares of the Fund if, and to the extent that, within a
period beginning 30 days before the date of such sale or disposition and ending
30 days after such date, the holder acquires (such as through dividend
reinvestment) securities that are substantially identical to the shares of the
Fund.
 
The Fund will generally be subject to an excise tax of 4% on the amount of any
income or capital gains, above certain permitted levels, distributed to
shareholders on a basis such that such income or gain is not taxable to
shareholders in the calendar year in which it was earned by the Fund.
Furthermore, dividends declared in October, November, or December payable to
shareholders of record on a specified date in such a month and paid in the
following January will be treated as having been paid by the Fund and received
by each shareholder in December. Under this rule, therefore, shareholders may be
taxed in one year on dividends or distributions actually received in January of
the following year.
 
Distributions of net long-term capital gains will have the effect of reducing
the net asset value of the Fund's shares by the amount of the distribution. If
the net asset value is reduced below a shareholder's cost, the distribution will
nonetheless be taxable as described above, even if the distribution represents a
return of invested capital. Investors should consider the tax implications of
buying shares just prior to a distribution, when the price of shares may reflect
the amount of the forthcoming distribution.
 
If a correct and certified taxpayer identification number is not on file, the
Fund is required, subject to certain exemptions, to withhold 31% of certain
payments made or distributions declared to non-corporate shareholders.
Shareholders should be aware that, under applicable regulations, the Fund may be
fined up to $50 annually for each account for which a certified taxpayer
identification number is not provided. In the event that such a fine is imposed
with respect to any uncertified account in any year, a corresponding charge may
be made against that account.
 
This discussion of tax consequences is based on U.S. federal tax laws in effect
on the date of this Prospectus. These laws and regulations are subject to change
by legislative or administrative action, possibly with retroactive effect.
Investors are urged to consult their own tax advisors with respect to specific
questions as to federal taxes and with respect to the applicability of state or
local taxes. See 'Taxes' in the SAI.
 
ADDITIONAL INFORMATION
 
The Fund will send its shareholders annual and semi-annual reports. The
financial statements appearing in annual reports will be audited by independent
accountants. Shareholders also will be sent confirmations of each purchase and
redemption and periodic statements reflecting all account activity, including
dividends and any distributions whether reinvested in additional shares or
paid in cash.
 
Shareholders of certain Eligible Institutions may be given the privilege to
initiate transactions automatically by telephone upon opening an account.
However, an investor should be aware that a transaction authorized by telephone
and reasonably believed to be genuine by the Company, the Branch, the Eligible
Institution, the Transfer Agent or the Distributor may subject the investor to
risk of loss if such instruction is subsequently found not to be genuine. The
Company and its service providers will employ reasonable procedures, including
requiring investors to give a form of personal identification and tape recording
of telephonic instructions, to confirm that telephonic instructions by investors
are genuine; 
                                      -22-

if it does not, it or the service provider may be liable for any losses due to
unauthorized or fraudulent instructions.
 
The Fund may make historical performance information available and may compare
its performance to other investments or relevant indices, including data from
Lipper Analytical Services, Inc., the Salomon Brothers Long Term High Yield
Index, the Merrill Lynch All High Yield Bond Index, Micropal Inc., Morningstar
Inc., Ibbotson Associates, Standard & Poor's 500 Composite Stock Price Index,
the Dow Jones Average, the Frank Russell Indices, the Morgan Stanley EAFE Index,
the Financial Times World Stock Index and other industry publications.
 
The Fund may advertise 'yield'. Yield refers to the net income generated by an
investment in the Fund over a stated 30-day period. This income is then
annualized -- i.e., the amount of income generated by the investment during the
30-day period is assumed to be generated each 30-day period for 12 periods and
is shown as a percentage of the investment. The income earned on the investment
is also assumed to be reinvested at the end of the sixth 30-day period.
 
The Fund may also advertise 'total return'. The total return shows what an
investment in the Fund would have earned over a specified period of time (one,
five or ten years or since commencement of operations, if less) assuming that
all Fund distributions and dividends were reinvested on the reinvestment dates
and less all recurring fees during the period and assuming the redemption of
such investment at the end of each period.
 
These methods of calculating yield and total return are required by regulations
of the SEC. Yield and total return data similarly calculated, unless otherwise
indicated, over other specified periods of time may also be used. All
performance figures are based on historical earnings and are not intended to
indicate future performance. Performance information may be obtained by clients
of an Eligible Institution by calling the Eligible Institution, while other
shareholders may address their inquiries to the Transfer Agent.

BOSTON, MASSACHUSETTS 02116
FOR INFORMATION CALL (888) UBS-FUND ((888) 827-3863)
    
 
   
UBS Small Cap Fund (the 'Fund') seeks to provide long-term capital appreciation.
In order to accomplish this, the Sub-Adviser (defined below) intends to invest
primarily in a diversified portfolio of common stocks and other equity
securities of small capital growth companies that the Sub-Adviser believes offer
investors above average potential for capital appreciation. 'Small capital'
companies are companies with stock market capitalizations within the market
capitalization range of the stocks listed on the Russell 2000 Index. For further
information about 'small capital growth' companies, see 'Investment Objectives
and Policies.' There is no assurance that the Fund will achieve its stated
objective.
    
 
The Fund is a diversified, no-load mutual fund for which there are no sales
charges or exchange or redemption fees. The Fund is one of several series of UBS
Private Investor Funds, Inc. (the 'Company'), an open-end management investment
company organized as a corporation under Maryland law.
 
UNLIKE OTHER MUTUAL FUNDS THAT DIRECTLY ACQUIRE AND MANAGE THEIR OWN PORTFOLIO
OF SECURITIES, THE FUND SEEKS TO ACHIEVE ITS INVESTMENT OBJECTIVE BY INVESTING
ALL OF ITS INVESTABLE ASSETS IN UBS SMALL CAP PORTFOLIO (THE 'PORTFOLIO'). THE
PORTFOLIO IS A SERIES OF UBS INVESTOR PORTFOLIOS TRUST, (THE 'TRUST'), AN
OPEN-END MANAGEMENT INVESTMENT COMPANY. THE PORTFOLIO HAS THE SAME INVESTMENT
OBJECTIVE AS THE FUND. THE FUND EMPLOYS A TWO-TIER MASTER-FEEDER INVESTMENT FUND
STRUCTURE THAT IS MORE FULLY DESCRIBED UNDER THE SECTION CAPTIONED
'MASTER-FEEDER STRUCTURE'.
 
The Portfolio is advised by the New York Branch (the 'Branch' or the 'Adviser')
of Union Bank of Switzerland (the 'Bank') and UBS Asset Management (New York)
Inc. (the 'Sub-Adviser' and, together with the Adviser, the 'Advisers').
 
   
This Prospectus sets forth concisely the information about the Fund that a
prospective investor ought to know before investing. It should be read and
retained for future reference. A Statement of Additional Information, dated
September 8, 1997 (the 'SAI'), provides further discussion of certain topics
referred to in this Prospectus and other matters that may be of interest to
investors. The SAI has been filed with the Securities and Exchange Commission,
is incorporated herein by reference, and is available without charge upon
written request from the Company or Distributor (as defined herein) at the
addresses set forth on the back cover of the Prospectus, or by calling (888)
UBS-FUND ((888) 827-3863).
    
 
INVESTMENTS IN THE FUND ARE NOT DEPOSITS WITH OR OBLIGATIONS OF, OR GUARANTEED
OR ENDORSED BY, UNION BANK OF SWITZERLAND OR ANY OTHER BANK. SHARES OF THE FUND
ARE NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL
RESERVE BOARD, OR ANY OTHER GOVERNMENT AGENCY. AN INVESTMENT IN THE FUND IS
SUBJECT TO RISKS THAT MAY CAUSE THE VALUE OF THE INVESTMENT TO FLUCTUATE. WHEN
THE INVESTMENT IS REDEEMED, THE VALUE MAY BE HIGHER OR LOWER THAN THE AMOUNT
ORIGINALLY INVESTED BY THE INVESTOR.
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

UBS SMALL CAP FUND
INVESTORS FOR WHOM THE FUND IS DESIGNED
    
 
   
UBS Small Cap Fund (the 'Fund') is designed for investors seeking long-term
capital appreciation. Because of the risks associated with common stock
investments, the Fund is intended to be a long-term investment vehicle and is
not intended to provide investors with a means for speculating on short-term
market movements. The Fund seeks to achieve its investment objective by
investing all of its investable assets in UBS Small Cap Portfolio (the
'Portfolio'). The Portfolio is a series of UBS Investor Portfolios Trust (the
'Trust'), an open-end management investment company. The Portfolio has the same
investment objective as the Fund. Because the investment characteristics and
experience of the Fund will correspond directly with those of the Portfolio, the
discussion in this Prospectus focuses on the investments and investment policies
of the Portfolio. The net asset value of shares of the Fund fluctuates with
changes in the value of the investments in the Portfolio.
    
 
   
The Portfolio may make various types of investments in seeking its objective.
Among the permissible investments for the Portfolio are equity securities of
domestic issuers with market capitalizations at the time of acquisition by the
Portfolio within the market capitalization range of those stocks listed on the
Russell 2000 Index. Equity securities include common stocks and securities which
are convertible into common stocks. The Portfolio may also invest in futures
contracts, options and certain privately placed securities. The Portfolio's
investments in securities of smaller or less established issuers involve risks
and may be more volatile and less liquid than the securities of larger or more
established domestic issuers. For further information about these investments
and related investment techniques, see 'Investment Objective and Policies'
discussed below.
    
 
The minimum initial investment in the Fund is $25,000, except that the minimum
initial investment is $10,000 for shareholders of another series of UBS Private
Investor Funds, Inc. (the 'Company'). The minimum subsequent investment for all
investors is $5,000. These minimums may be waived at the Fund's discretion. See
'Purchase of Shares'. If shareholders reduce their total investment in shares of
the Fund to less than $10,000, their investment will be subject to mandatory
redemption. See 'Redemption of Shares -- Mandatory Redemption'. The Fund is one
of several series of the Company, an open-end management investment company
organized as a Maryland corporation.
 
This Prospectus describes the investment objective and policies, management and
operations of the Fund to enable investors to decide if the Fund suits their
investment needs. The Fund operates through a two-tier master-feeder investment
fund structure. The Company's Board of Directors (the 'Directors' or the
'Board') believes that this structure provides Fund shareholders with the
opportunity to achieve certain economies of scale that would otherwise be
unavailable if the shareholders' investments were not pooled with other
investors sharing similar investment objectives.
 
The following table illustrates that investors in the Fund incur no shareholder
transaction expenses: their investments in the Fund are subject only to the
operating expenses set forth below for the Fund and the Portfolio, as a
percentage of average daily net assets of the Fund. The Directors believe that
the aggregate per share expenses of the Fund and the Portfolio will be
approximately equal to and may be less than the expenses that the Fund would
incur if it retained the services of an investment adviser and invested its
assets directly in portfolio securities. Fund and Portfolio expenses are
discussed below under the headings 'Management', 'Expenses' and 'Shareholder
Services'.

</TABLE>
 
*   Expenses are expressed as a percentage of the Fund's projected average daily
net assets and are based on the annualized estimates of expenses expected to be
incurred during the fiscal period ending December 31, 1997, after any applicable
fee waivers and expense reimbursements. Without such fee waivers and expense
reimbursements, Total Operating Expenses are estimated to be equal, on an annual
basis, to 1.75% of the Fund's projected average daily net assets. See
'Management'.
 
**  The New York Branch (the 'Branch' or the 'Adviser') of Union Bank of
Switzerland (the 'Bank') has agreed to waive fees and reimburse each of the Fund
and the Portfolio for any of their respective operating expenses to the extent
that the Fund's total operating expenses (including its share of the Portfolio's
expenses) exceed, on an annual basis, 1.20% of the Fund's average daily net
assets. The Branch may modify or discontinue this undertaking at any time in the
future with 30 days' prior notice to the Fund. The Portfolio's advisory fee
would be equal, on an annual basis, to 0.60% of the average daily net assets of
the Portfolio if there were no fee waiver in effect. See 'Management -- Adviser
and Funds Services Agent' and 'Expenses'.
 
*** The fees and expenses in Other Expenses include fees payable to:
     (i) Investors Bank & Trust Company ('Investors Bank', the 'Custodian' or
     the 'Transfer Agent') (a) under an Administration Agreement with the Fund,
     (b) as custodian of the Fund and the Portfolio and (c) as transfer agent of
     the Fund,
     (ii) Investors Fund Services (Ireland) Limited ('IBT Ireland') under an
     Administration Agreement with the Portfolio, and
     (iii) Eligible Institutions providing shareholder services under various
     shareholder servicing agreements.
 
For a more detailed description of contractual fee arrangements, including fee
waivers and expense reimbursements, and of the fees and expenses included in
Other Expenses, see 'Management' and 'Shareholder Services'.
 
EXAMPLE
 
An investor would pay the following expenses on a $1,000 investment, assuming a
5% annual return and redemption at the end of each time period:

The above Expense Table is designed to assist investors in understanding the
various direct and indirect costs and expenses that Fund investors are expected
to bear and reflects the expenses of the Fund and the Fund's share of the
Portfolio's expenses. In connection with the above Example, please note that
$1,000 is less than the Fund's minimum investment requirement and that there are
no redemption or exchange fees of any kind. See 'Purchase of Shares', 'Exchange
of Shares' and 'Redemption of Shares'. THE EXAMPLE IS HYPOTHETICAL; IT IS
INCLUDED SOLELY FOR ILLUSTRATIVE PURPOSES, AND ASSUMES THE CONTINUATION OF THE
FEE WAIVERS AND EXPENSE REIMBURSEMENTS REPRESENTED IN THE ABOVE 'EXPENSE TABLE'.
IT SHOULD NOT BE CONSIDERED A REPRESENTATION OF FUTURE PERFORMANCE; ACTUAL
EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN.

HISTORICAL PERFORMANCE OF COMPARABLE DISCRETIONARY ACCOUNTS. The following table
sets forth (i) the composite total return for the one, three, five and ten year
periods ended June 30, 1997 for all discretionary accounts described below that
have been managed for at least one full quarter by UBS Asset Management (New
York) Inc., a wholly-owned subsidiary of the Bank ('UBSAM'), and (ii) the
average annual total returns during the same periods for the Russell 2000 Index
(the 'Index'). The discretionary accounts described in (i) above have
substantially the same investment objective and policies and are managed in a
manner substantially the same as the Portfolio. The composite total return for
such accounts has been adjusted to deduct all of the Fund's annual total
operating expenses of 1.20% of average daily net assets as set forth in the
Expense Table above. The composite total return is time-weighted and weighted by
individual account size and reflects the reinvestment of dividends and interest.
The discretionary accounts are not subject to certain investment limitations,
diversification requirements and other restrictions imposed by federal
securities and tax laws on the Portfolio that, if applied to the accounts, may
have adversely affected their performance results. The composite total return of
these discretionary accounts does not represent the historical performance of
the Portfolio and should not be viewed as a prediction of future performance of
the Portfolio. The Index is an unmanaged index that includes 2,000 U.S. small
capitalization stocks and is a common measure of the performance of the small
capitalization segment of the U.S. stock market. The total returns of the Index
do not include management fees or commissions.

MASTER-FEEDER STRUCTURE
 
Unlike other mutual funds that directly acquire and manage their own portfolio
of securities, the Fund seeks to achieve its investment objective by investing
all of its investable assets in the Portfolio, a separate investment company
with the same investment objective as the Fund. The investment objective of the
Fund and the Portfolio may be changed only with the approval of the holders of a
majority of the outstanding voting securities of the Fund or a majority of the
investors in the Portfolio, respectively, after 30 days' prior notice.
 
This master-feeder structure has been developed relatively recently, so
shareholders should carefully consider this investment approach.
 
In addition to selling an interest in the Portfolio to the Fund, the Portfolio
may sell interests in the Portfolio to other mutual funds or institutional
investors. Such investors will invest in the Portfolio on the same terms and
conditions as the Fund and will incur a proportionate share of the Portfolio's
expenses. However, other entities investing in the Portfolio may sell shares of
their own fund using a different pricing structure than the Fund's. Such
different pricing structures may result in differences in returns experienced by
investors in other funds that invest in the Portfolio. Such differences in
returns are not uncommon and are present in other mutual fund structures.
Information concerning other holders of interests in the Portfolio is available
from Investors Bank at (888) UBS-FUND.
 
The Fund may withdraw its investment in the Portfolio at any time if the Board
determines that it is in the Fund's best interest to do so. Upon any such
withdrawal, the Board would consider what action might be taken, including the
investment of all the Fund's assets in another pooled investment entity having
the same investment objective and restrictions as the Fund or the retaining of
an investment adviser to manage the Fund's assets in accordance with the
investment policies described below with respect to the Portfolio.

Certain changes in the Portfolio's investment objective, policies or
restrictions, or a failure by the Fund's shareholders to approve a change in the
Portfolio's investment objective or restrictions, may require the Fund to
withdraw its investments in the Portfolio. Any such withdrawal could result in
an in-kind distribution of portfolio securities (as opposed to a cash
distribution) by the Portfolio to the Fund. Such a distribution may result in
the Fund's having a less diversified portfolio of investments or adversely
affect the Fund's liquidity, and the Fund could incur brokerage, tax or other
charges in converting such securities to cash. Notwithstanding the above, there
are other means for meeting shareholder redemption requests, such as borrowing.
 
Smaller funds investing in the Portfolio may be materially affected by the
actions of larger funds investing in the Portfolio. For example, if a large fund
withdraws from the Portfolio, the remaining funds may subsequently experience
higher pro rata operating expenses, thereby lowering returns. Additionally,
because the Portfolio would become smaller, it may become less diversified,
resulting in potentially increased portfolio risk (however, these possibilities
also exist for traditionally structured funds that have large or institutional
investors who may withdraw from a fund). Also, funds with a greater pro rata
ownership in the Portfolio could have effective voting control of its
operations. Except as permitted by the Securities and Exchange Commission (the
'SEC'), whenever the Fund is requested to vote on matters pertaining to the
Portfolio, the Company will hold a meeting of Fund shareholders and will cast
all of its votes proportionately as instructed by the Fund's shareholders. See
'Organization' in the SAI. Fund shareholders who do not vote will not affect the
Fund's votes at the Portfolio meeting. The percentage of the Company's votes
representing Fund shareholders not voting will be voted by the Company in the
same proportion as the Fund shareholders who do, in fact, vote.
 
For more information about the Portfolio's investment objective, policies and
restrictions, see 'Investment Objective and Policies', 'Additional Investment
Information and Risk Factors' and 'Investment Restrictions'. For more
information about the Portfolio's management and expenses, see 'Management'. For
more information about changing the investment objective, policies and
restrictions of the Fund or the Portfolio, see 'Investment Restrictions'.
 
INVESTMENT OBJECTIVE AND POLICIES
 
The investment objective of the Fund and the Portfolio is described below,
together with the policies each employs to seek to achieve its objective.
Additional information about the investment policies of the Fund and the
Portfolio appears in the SAI under 'Investment Objectives and Policies'. The
Fund seeks to achieve its investment objective by investing all of its
investable assets in the Portfolio, which has the same investment objective as
the Fund. There can be no assurance that the investment objective of the Fund or
the Portfolio will be achieved.
 
The Adviser is responsible for supervising the management of the Portfolio's
investments. Consistent with these duties, the Adviser has entered into a
Sub-Advisory Agreement with UBSAM (the 'Sub-Adviser' and, together with the
Adviser, the 'Advisers'), whereby the Sub-Adviser is primarily responsible for
the day-to-day investment decisions for the Portfolio. The Adviser is solely
responsible for paying the Sub-Adviser for these services. The Sub-Adviser is an
affiliate of the Adviser.
 
   
The Portfolio's objective is to provide long-term capital appreciation. In order
to accomplish this, the Portfolio intends to invest primarily in a diversified
portfolio of common stocks, preferred stocks and other securities (such as
warrants and rights) that are either convertible into or exchangeable for common
stocks of small capital growth companies. The Portfolio defines 'small capital'
companies as companies whose market capitalization at the time of acquisition by
the Portfolio is within the market capitalization range of those stocks listed
on the Russell 2000 Index. 'Growth' companies are generally rapidly growing
companies and may include companies still in the developmental stage or older
companies that appear to be entering a new stage of growth owing to factors such
as management changes or new technology, products or markets and may include
providers of products or services with a high unit volume growth rate.
    
 
   
The Portfolio may also invest up to 20% of its assets in foreign securities,
including American Depository Receipts ('ADRs'), which the Sub-Adviser believes
meet the Portfolio's investment objective and relevant
    
 
                                      -5-
 



<PAGE>
<PAGE>
policies. See 'Foreign Investment Information' and 'Foreign Currency Exchange
Transactions' under 'Additional Investment Information and Risk Factors'.
 
Under normal circumstances, the Portfolio will invest at least 65% of its assets
in small capital growth companies. The Portfolio may also invest in securities
of emerging growth companies -- i.e. small or medium sized companies that have
passed their start-up phase and that show positive earnings and prospects of
achieving significant profit and gain in a relatively short period of time.
Emerging growth companies generally stand to benefit from new products, services
or processes, technological developments or changes in management and other
factors and include smaller companies experiencing unusual developments
affecting their market values.
 
The Portfolio will invest, on an individual security basis, in companies
believed by the Advisers to represent above average growth opportunities. The
Sub-Adviser will select individual securities for investment by screening for
above average growth expectations and reasonable valuations. Growth company
securities may have above average price volatility. The Portfolio attempts to
reduce its overall exposure to the risk of declines in individual security
prices by diversifying its investments over a carefully selected list of
securities issued by different companies in a variety of industries.
 
Although the Portfolio intends to invest primarily in equity securities, under
normal market conditions it may invest up to 20% of its assets in certain cash
investments and certain short-term fixed income securities. See 'Investment
Objectives and Policies -- Quality and Diversification Requirements' in the SAI.
Such securities may be used to invest uncommitted cash balances, to maintain
liquidity to meet shareholder redemptions or to take a temporarily defensive
position against potential stock market declines. These securities include:
obligations of the United States Government and its agencies or
instrumentalities; money market mutual funds, commercial paper, bank
certificates of deposit and bankers' acceptances; and repurchase agreements
collateralized by these securities. Under market conditions where the Portfolio
or its Adviser has adopted a defensive investment posture, the Portfolio may
invest without limit in these securities. The Portfolio may also purchase
nonpublicly offered debt securities. See 'Additional Investment Information and
Risk Factors -- Illiquid Investments; Privately Placed and Other Unregistered
Securities'.
 
The Portfolio may also utilize equity futures contracts and options to a limited
extent. Specifically, the Portfolio may enter into futures contracts and options
provided that such positions are established for hedging purposes only. See
'Futures Contracts'.
 
The Portfolio may also sell securities short to a limited extent and for hedging
purposes only. See 'Short Sales'. The Fund may also invest in 'special
situations'. See 'Special Situations'.
 
The Portfolio intends to manage its securities actively in pursuit of its
investment objective. Although it generally seeks to invest for the long-term,
the Portfolio retains the right to sell securities irrespective of how long they
have been held. It is anticipated that the annual portfolio turnover of the
Portfolio will range between 50% and 150%. To the extent the Portfolio engages
in short-term trading, it may incur increased transaction costs.
 
ADDITIONAL INVESTMENT INFORMATION AND RISK FACTORS
 
SMALL CAPITAL GROWTH AND EMERGING GROWTH COMPANIES. Because the securities of
small capital growth and emerging growth companies, particularly those traded
over-the-counter, may have more limited marketability than those of larger, more
seasoned companies, or market averages in general, investing in small capital
growth or emerging growth companies may involve greater than average risks. The
value of the Fund's shares may fluctuate more widely than the value of shares of
a fund that invests primarily in larger, more established companies. Normally
small capital growth companies have fewer shares outstanding than larger
companies; consequently, it may be more difficult to buy or sell significant
amounts of such shares without an unfavorable impact on prevailing prices. Small
capital growth companies may have limited product lines, markets or financial
resources and may lack management depth. There is typically less publicly
available information concerning smaller issuers than for larger, more
established companies.

<PAGE>
<PAGE>

SPECIAL SITUATIONS. From time to time, the Portfolio may invest in special
situations. A special situation arises when the Sub-Adviser believes that the
securities of a particular issuer will be recognized and appreciate in value due
to a specific development affecting that issuer. Developments that might create
a special situation include a new product or process, a technological
breakthrough, a management change, merger, recapitalization or other
extraordinary corporate event, or a change in market supply of and demand for
the security. Investments in special situations may carry an additional risk of
loss in the event that the anticipated development does not occur or does not
result in the anticipated market reaction.
 
SHORT SALES. In the event that the Sub-Adviser anticipates that the price of a
security will decline, the Sub-Adviser may sell the security short and borrow
the same security from a broker or other institution to complete the sale. The
Portfolio will incur a profit or a loss, depending upon whether the market price
of the security decreases or increases between the date of the short sale and
the date on which the Fund must replace the borrowed security. The Portfolio
will only enter into short sales for hedging purposes. All short sales will be
fully collateralized and the Portfolio will not sell securities short if
immediately after and as a result of the short sale the value of all securities
sold by the Portfolio exceeds 25% of its total assets. The Fund also limits
short sales of any one issuer's securities to 2% of the Fund's total assets and
to 2% of any one class of the issuer's securities.
 
CONVERTIBLE SECURITIES. The convertible securities in which the Portfolio may
invest include any debt securities or preferred stocks that may be converted
into common stock or that carry the right to purchase common stock. Convertible
securities entitle the holder to exchange the securities for a specified number
of shares of common stock, usually of the same company, at specified prices
within a certain period of time.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Portfolio may purchase
securities on a when-issued or delayed delivery basis. Delivery of and payment
for these securities may take as long as a month or more after the date of the
purchase commitment. The value of these securities is subject to market
fluctuation during this period and no interest or income accrues to the
Portfolio until settlement. At the time of settlement, a when-issued security
may be valued at less than its purchase price. Between the trade and settlement
dates, the Portfolio will maintain a segregated account with the Custodian
consisting of a portfolio of liquid securities with a value at least equal to
these commitments. When entering into a when-issued or delayed delivery
transaction, the Portfolio will rely on the other party to consummate the
transaction; if the other party fails to do so, the Portfolio may be
disadvantaged. It is the current policy of the Portfolio not to enter into
when-issued commitments exceeding in the aggregate 15% of the market value of
the Portfolio's total assets less liabilities (excluding the obligations created
by these commitments).
 
REPURCHASE AGREEMENTS. The Portfolio may engage in repurchase agreement
transactions with brokers, dealers or banks that meet the credit guidelines
approved by the Trust's Board of Trustees (the 'Trustees'). In a repurchase
agreement, the Portfolio buys a security from a seller that has agreed to
repurchase it at a mutually agreed upon date and price, reflecting the interest
rate effective for the term of the agreement. The term of these agreements is
usually from overnight to one week. A repurchase agreement may be viewed as a
fully collateralized loan of money by the Portfolio to the seller. The Portfolio
always receives securities as collateral with a market value at least equal to
the purchase price plus accrued interest and this value is maintained during the
term of the agreement. If the seller defaults and the collateral's value
declines, the Portfolio might incur a loss. If bankruptcy proceedings are
commenced with respect to the seller, the Portfolio's realization upon the
disposition of collateral may be delayed or limited. Investments in repurchase
agreements maturing in more than seven days and certain other investments that
may be considered illiquid are limited. See 'Illiquid Investments; Privately
Placed and Other Unregistered Securities' below.
 
REVERSE REPURCHASE AGREEMENTS. The Portfolio is permitted to enter into reverse
repurchase agreements. In a reverse repurchase agreement, the Portfolio sells a
security and agrees to repurchase it at a mutually agreed upon date and price,
reflecting the interest rate effective for the term of the agreement. It may
also be viewed as the borrowing of money by the Portfolio and, therefore, is a
form of leverage. Leverage may cause any gains or losses of the Portfolio to be
magnified. For more information, including
 
                                      -7-
 



<PAGE>
<PAGE>
limitations on the use of reverse repurchase agreements, see 'Investment
Objectives and Policies' in the SAI and 'Investment Restrictions' below.
 
SECURITIES LENDING. Subject to applicable investment restrictions, the Portfolio
may lend its securities. The Portfolio may lend its securities if such loans are
secured continuously by cash or equivalent collateral or by a letter of credit
in favor of the Portfolio at least equal at all times to 100% of the market
value of the securities loaned, plus accrued interest. While such securities are
on loan, the borrower will pay the Portfolio any income accruing thereon. Loans
will be subject to termination by the Portfolio in the normal settlement time,
generally three business days after notice, or by the borrower on one day's
notice. Borrowed securities must be returned when the loan is terminated. Any
gain or loss in the market price of the borrowed securities that occurs during
the term of the loan inures to the Portfolio and its respective investors. The
Portfolio may pay reasonable finders' and custodial fees in connection with a
loan. In addition, the Portfolio will consider all the facts and circumstances,
including the creditworthiness of the borrowing financial institution, and the
Portfolio will not make any loans in excess of one year. The Portfolio will not
lend its securities to any officer, Trustee, Director, employee or affiliate or
placement agent of the Company, the Portfolio, or the Adviser, Sub-Adviser,
Administrator or Distributor, unless otherwise permitted by applicable law.
 
FOREIGN INVESTMENT INFORMATION. Investments in securities of foreign issuers and
in obligations of foreign branches of domestic banks involve somewhat different
investment risks from those affecting securities of domestic issuers. There may
be limited publicly available information with respect to foreign issuers, and
foreign issuers are not generally subject to uniform accounting, auditing and
financial standards and requirements comparable to those applicable to domestic
companies. Dividends and interest paid by foreign issuers may be subject to
withholding and other foreign taxes that may decrease the net return on such
investments.
 
Investors should realize that the value of the Portfolio's investments in
foreign securities may be adversely affected by changes in political or social
conditions, diplomatic relations, confiscatory taxation, expropriation,
nationalization, limitation on the removal of funds or assets, or imposition of
(or change in) exchange control or tax regulations in those foreign countries.
In addition, changes in government administrations or economic or monetary
policies in the United States or abroad could result in appreciation or
depreciation of portfolio securities and could favorably or unfavorably affect
the Portfolio's operations. Furthermore, the economies of individual foreign
nations may differ from the U.S. economy, favorably or unfavorably, in areas
such as growth of gross national product, rate of inflation, capital
reinvestment, resource self-sufficiency and balance of payments position; it may
also be more difficult to obtain and enforce a judgment against a foreign
issuer. Any foreign investments made by the Portfolio must be made in compliance
with U.S. and foreign currency restrictions and tax laws restricting the amounts
and types of foreign investments.
 
In addition, while the volume of transactions effected on foreign stock
exchanges has increased in recent years, in most cases it remains appreciably
below that of domestic security exchanges. Accordingly, the Portfolio's foreign
investments may be less liquid and their prices may be more volatile than
comparable investments in securities of U.S. companies. Moreover, the settlement
periods for foreign securities, which are often longer than those for securities
of U.S. issuers, may affect portfolio liquidity. In buying and selling
securities on foreign exchanges, purchasers normally pay fixed commissions that
are generally higher than the negotiated commissions charged in the United
States. In addition, there is generally less government supervision and
regulation of securities exchanges, brokers and issuers located in countries
other than in the United States.
 
The Portfolio may invest in securities of foreign issuers directly or in the
form of American Depository Receipts ('ADRs'), European Depository Receipts
('EDRs') Global Depository Receipts ('GDRs') or other similar securities of
foreign issuers. These securities may not necessarily be denominated in the same
currency as the securities they represent. ADRs are receipts typically issued by
a U.S. bank or trust company evidencing ownership of the underlying foreign
securities. Certain institutions issuing ADRs may not be sponsored by the issuer
of the underlying foreign securities. A non-sponsored depository may not provide
the same shareholder information that a sponsored depository is required to
provide under its contractual arrangements with the foreign issuer. EDRs are
receipts issued by a European financial
 
                                      -8-
 



<PAGE>
<PAGE>

institution evidencing a similar arrangement. GDRs are issued outside the United
States, typically by non-U.S. banks and trust companies. Generally, ADRs, in
registered form, are designed for use in the U.S. securities markets, and EDRs
and GDRs, in bearer form, are designed for use in European securities markets
and domestic and European securities markets, respectively.
 
Because investments in foreign securities involve foreign currencies, the value
of assets as measured in U.S. dollars may be affected, favorably or unfavorably,
by changes in currency exchange rates and in exchange control regulations,
including currency blockage. See 'Foreign Currency Exchange Transactions' below.
 
FOREIGN CURRENCY EXCHANGE TRANSACTIONS. Because the Portfolio may buy and sell
securities and receive interest and dividends in currencies other than the U.S.
dollar, the Portfolio may, from time-to-time, enter into foreign currency
exchange transactions. The Portfolio may enter into these transactions on a spot
(i.e., cash) basis at the spot rate prevailing in the foreign currency exchange
market, use forward currency contracts to purchase or sell foreign currencies,
use currency futures contracts or purchase or sell options thereon or purchase
or sell currency options.
 
A forward foreign currency exchange contract is an obligation of the Portfolio
to purchase or sell a specific currency at a future date, which may be any fixed
number of days from the date of the contract. Currency options give the buyer
the right, but not the obligation, to purchase or sell a fixed amount of a
specific currency at a fixed price at a future date. These contracts are entered
into in the interbank market directly between currency traders (usually large
commercial banks) and their customers. A forward foreign currency exchange
contract generally has no deposit requirement, and is traded at a net price
without commission. The Portfolio will not enter into these foreign currency
exchange transactions for speculative purposes. Foreign currency exchange
transactions do not eliminate fluctuations in the local currency prices of the
Portfolio's securities or in foreign exchange rates, or prevent loss if the
local currency prices of these securities should decline.
 
A currency futures contract is a contract involving an obligation to deliver or
acquire the specified amount of a currency at a specified price at a specified
future time. Futures contracts may be settled on a net cash payment basis rather
than by the sale and delivery of the underlying currency.
 
The Portfolio may enter into foreign currency exchange transactions in an
attempt to protect against changes in foreign currency exchange rates between
the trade and settlement dates of specific securities transactions or
anticipated securities transactions. The Portfolio may use these techniques to
hedge against change in foreign currency exchange rates (with the U.S. dollar or
other foreign currencies) that would cause a decline in the value of existing
investments denominated or principally traded in a foreign currency.
 
Although these transactions are intended to minimize the risk of loss due to a
decline in the value of the hedged currency, these transactions also limit any
potential gain that might be realized should the value of the hedged currency
increase. Additionally, the premiums paid by the Portfolio for currency or
futures options increase the Portfolio's transaction costs. Similarly, the cost
of the Portfolio's spot currency exchange transactions is generally the
difference between the bid and offer spot rate of the currency being purchased
or sold. The precise matching of these transactions and the value of the
securities involved will not generally be possible because the future value of
such securities in foreign currencies will change as a consequence of market
movements in the value of such securities between the date such a transaction is
entered into and the date it matures. The projection of currency market
movements is extremely difficult and the successful execution of a hedging
strategy is highly uncertain.
 
ILLIQUID INVESTMENTS; PRIVATELY PLACED AND OTHER UNREGISTERED SECURITIES. The
Portfolio may not acquire any illiquid securities if, as a result thereof, more
than 25% of the market value of the Portfolio's net assets would be in illiquid
investments or investments that are not readily marketable. In addition, the
Portfolio will not invest more than 10% of the market value of its total assets
in restricted securities (not including Rule 144A securities) that cannot be
offered for public sale in the United States without first being registered
under the Securities Act of 1933, as amended (the 'Securities Act'). Subject to
those non-fundamental policy limitations, the Portfolio may acquire investments
that are illiquid or have limited liquidity, such as private placements or
investments that are not registered under the Securities
 
                                      -9-
 



<PAGE>
<PAGE>
Act, and cannot be offered for public sale in the United States without first
being registered. An illiquid investment is any investment that cannot be
disposed of within seven days in the normal course of business at approximately
the amount at which it is valued by the Portfolio. Repurchase agreements
maturing in more than seven days are considered illiquid investments and, as
such, are subject to the limitations set forth in this paragraph. The price the
Portfolio pays for illiquid securities or receives upon resale may be lower than
the price paid or received for similar securities with a more liquid market.
Accordingly, the valuation of these securities will reflect any limitations on
their liquidity.
 
The Portfolio may also purchase Rule 144A securities sold to institutional
investors without registration under the Securities Act. These securities may be
determined to be liquid in accordance with guidelines established by the Adviser
and approved by the Trustees of the Trust. The Trustees of the Trust will
monitor the Adviser's implementation of these guidelines on a periodic basis.
 
MONEY MARKET INSTRUMENTS. The Portfolio is permitted to invest in money market
instruments although it intends to stay invested in equity securities to the
extent practical in light of its objective and long-term investment perspective.
The Portfolio may make money market investments pending other investments or
settlements, for liquidity or in adverse market conditions. Such money market
investments may include obligations of the U.S. Government and its agencies and
instrumentalities, money market mutual funds, commercial paper, bank obligations
and repurchase agreements. For more detailed information about these money
market investments, see 'Investment Objectives and Policies' in the SAI.
 
FUTURES AND OPTIONS TRANSACTIONS. The Portfolio is permitted to enter into the
futures and options transactions described below. These instruments are commonly
known as derivatives.
 
The Portfolio may purchase and sell exchange traded and over-the-counter ('OTC')
put and call options on equity securities or indices of equity securities, enter
into forward contracts, purchase and sell futures contracts on indices of equity
securities and purchase or sell put and call options on futures contracts on
indices of equity securities. The Portfolio may use these techniques for hedging
or risk management purposes or, subject to certain limitations, for investment
purposes in lieu of investing directly in the corresponding securities or
instruments. Such use of derivatives may be considered speculative.
 
The Portfolio may use these techniques to manage its exposure to changing
interest rates and/or security prices. Some options and futures strategies,
including selling futures contracts and buying puts, tend to hedge the
Portfolio's investments against price fluctuations. Other strategies, including
buying futures contracts, writing puts and calls, and buying calls, may tend to
increase market exposure. For example, if the Portfolio wishes to obtain
exposure to a particular market or market sector but does not wish to purchase
the relevant securities, it could, as an alternative, purchase a futures
contract on an index of such securities or related securities. Such a purchase
would not constitute a hedging transaction and could be considered speculative.
However, the Portfolio will use futures contracts or options in this manner only
for the purpose of obtaining the same level of exposure to a particular market
or market sector that it could have obtained by purchasing the relevant
securities and will not use futures contracts or options to leverage its
exposure beyond this level. The use of options and futures may involve some
leverage; such leverage is reduced by the requirement of the SEC to 'cover' such
obligations. See 'Cover -- Segregated Accounts' below. Options and futures
contracts may be combined with each other or with forward contracts in order to
adjust the risk and return characteristics of the Portfolio's overall strategy
in a manner deemed appropriate to the Adviser and consistent with the
Portfolio's objective and policies. Because combined positions involve multiple
trades, they result in higher transaction costs and may be more difficult to
open and close out.
 
The Portfolio's use of these transactions is a highly specialized activity,
which involves investment strategies and risks different from those associated
with ordinary portfolio securities transactions, and there can be no guarantee
that their use will increase the Portfolio's return. While the Portfolio's use
of these instruments may reduce certain risks associated with owning its
portfolio securities, these techniques themselves entail certain other risks. If
the Adviser applies a strategy at an inappropriate time or judges market
conditions or trends incorrectly, such strategies may lower the Portfolio's
return. Certain strategies limit the Portfolio's opportunity to realize gains as
well as limiting its exposure to losses. The Portfolio could experience losses
if the prices of its options and futures positions were poorly correlated with
its other investments, or if it could not close out its positions because of an
illiquid secondary
 
                                      -10-
 



<PAGE>
<PAGE>
market. In addition, the Portfolio will incur costs, including commissions and
premiums, in connection with these transactions and these transactions could
significantly increase the Portfolio's turnover rate.
 
The Portfolio may purchase and sell put and call options on securities, indices
of securities and futures contracts, or purchase and sell futures contracts for
the purposes described herein.
 
In addition, in order to assure that the Portfolio will not be considered a
'commodity pool' for purposes of Commodity Futures Trading Commission ('CFTC')
rules, the Portfolio will enter into transactions in futures contracts or
options on futures contracts only if (1) such transactions constitute bona fide
hedging transactions as defined under CFTC rules, or (2) no more than 5% of the
Portfolio's net assets are committed as initial margin or premiums to positions
that do not constitute bona fide hedging transactions.
 
OPTIONS
 
PURCHASING PUT AND CALL OPTIONS. By purchasing a put option, the Portfolio
obtains the right (but not the obligation) to sell the instrument underlying the
option at a fixed strike price. In return for this right, the Portfolio pays the
current market price for the option (known as the option premium). Options have
various types of underlying instruments, including specific securities, indices
of securities, indices of securities prices and futures contracts. The Portfolio
may terminate its position in a put option it has purchased by allowing it to
expire or by exercising the option. The Portfolio may also close out a put
option position by entering into an offsetting transaction, if a liquid market
exists. If the option is allowed to expire, the Portfolio will lose the entire
premium it paid. If the Portfolio exercises a put option on a security, it will
sell the instrument underlying the option at the strike price. If the Portfolio
exercises an option on an index, settlement is in cash and does not involve the
actual sale of securities. American style options may be exercised on any day up
to their expiration date. European style options may be exercised only on their
expiration date.
 
The buyer of a typical put option can expect to realize a gain if the price of
the underlying instrument falls substantially. However, if the price of the
instrument underlying the option does not fall enough to offset the cost of
purchasing the option, a put buyer can expect to suffer a loss (limited to the
amount of the premium paid, plus related transaction costs).
 
The features of call options are essentially the same as those of put options,
except that the purchaser of a call option obtains the right to purchase, rather
than sell, the instrument underlying the option at the option's strike price. A
call buyer typically attempts to participate in potential price increases of the
instrument underlying the option with risk limited to the cost of the option and
related transaction costs if security prices fall. At the same time, the buyer
can expect to suffer a loss if security prices do not rise sufficiently to
offset the cost of the option.
 
SELLING (WRITING) PUT AND CALL OPTIONS. When the Portfolio writes a put option,
it takes the opposite side of the transaction from the option's purchaser. In
return for receipt of the premium, the Portfolio assumes the obligation to pay
the strike price for the instrument underlying the option if the other party to
the option chooses to exercise it. The Portfolio may seek to terminate its
position in a put option it writes before exercise by purchasing an offsetting
option in the market at its current price. If the market is not liquid for a put
option the Portfolio has written, however, the Portfolio must continue to be
prepared to pay the strike price while the option is outstanding, regardless of
price changes, and must continue to post margin as discussed below.
 
If the price of the underlying instrument rises, a put writer would generally
expect to profit, although its gain would be limited to the amount of the
premium it received. If security prices remain the same over time, it is likely
that the writer will also profit, because it should be able to close out the
option at a lower price. If security prices fall, however, the put writer would
expect to suffer a loss. This loss should be less than the loss from purchasing
and holding the underlying instrument directly, however, because the premium
received for writing the option should offset a portion of the decline.
 
Writing a call option obligates the Portfolio to sell or deliver the option's
underlying instrument in return for the strike price upon exercise of the
option. The characteristics of writing call options are similar to those of
writing put options, except that writing calls generally is a profitable
strategy if prices
 
                                      -11-
 



<PAGE>
<PAGE>
remain the same or fall. Through receipt of the option premium a call writer
offsets part of the effect of a price decrease. At the same time, because a call
writer must be prepared to deliver the underlying instrument in return for the
strike price, even if its current value is greater, a call writer gives up some
ability to participate in security price increases.
 
The writer of a U.S. exchange traded put or call option on a security, an index
of securities or a futures contract is required to deposit cash or securities or
a letter of credit as margin and to make mark-to-market payments of variation
margin if and as the position becomes unprofitable.
 
OPTIONS ON INDICES. The Portfolio is permitted to enter into options
transactions and may purchase and sell put and call options on any securities
index based on securities in which the Portfolio may invest. Options on
securities indices are similar to options on securities, except that the
exercise of securities index options is settled by cash payment and does not
involve the actual purchase or sale of securities. In addition, these options
are designed to reflect price fluctuations in a group of securities or segment
of the securities market rather than price fluctuations in a single security.
The Portfolio, in purchasing or selling index options, is subject to the risk
that the value of its portfolio securities may not change as much as an index
because the Portfolio's investments generally will not match the composition of
an index.
 
For a number of reasons, a liquid market may not exist and thus the Portfolio
may not be able to close out an option position that it has previously entered
into. When the Portfolio purchases an OTC option, it will be relying on its
counterparty to perform its obligations, and the Portfolio may incur additional
losses if the counterparty is unable to perform.
 
FUTURES CONTRACTS
 
When the Portfolio purchases a futures contract, it agrees to purchase a
specified quantity of an underlying instrument at a specified future date and
price or to make or receive a cash payment based on the value of a securities
index. When the Portfolio sells a futures contract, it agrees to sell a
specified quantity of the underlying instrument at a specified future date and
price or to receive or make a cash payment based on the value of a securities
index. The price at which the purchase and sale will take place is fixed when
the Portfolio enters into the contract. Futures can be held until their delivery
dates or the positions can be (and normally are) closed out before then. There
is no assurance, however, that a liquid market will exist when a Portfolio
wishes to close out a particular position.
 
When the Portfolio purchases or sells a futures contract, the value of the
futures contract tends to increase and decrease in tandem with the value of its
underlying instrument. Purchasing futures contracts may tend to increase the
Portfolio's exposure to positive and negative price fluctuations in the
underlying instrument, much as if it had purchased the underlying instrument
directly, as discussed above. When the Portfolio sells a futures contract, by
contrast, the value of its futures position will tend to move in a direction
contrary to the value of the underlying instrument. Selling futures contracts on
securities similar to those held by the Portfolio, therefore, will tend to
offset both positive and negative market price changes, much as if the
underlying instrument had been sold. Because there are a limited number of types
of exchange-traded options and futures contracts, it is likely that these
standardized instruments will not exactly match the Portfolio's current or
anticipated investments. The Portfolio may invest in futures contracts and
options thereon based on currencies or on securities with different issuers,
maturities, or other characteristics from the securities in which it typically
invests, which involves a risk that the options or futures position will not
track the performance of the Portfolio's other investments. The Portfolio may
also enter into transactions in futures contracts and options for non-hedging
purposes, as discussed above.
 
The purchaser or seller of a futures contract is not required to deliver or pay
for the underlying instrument unless the contract is held until the delivery
date. However, when the Portfolio buys or sells a futures contract it will be
required to deposit 'initial margin' either with the Custodian in a segregated
account in the name of its futures broker, known as a futures commission
merchant ('FCM'), or with the FCM. Initial margin deposits are typically equal
to a small percentage of the contract's value. If the value of either party's
position declines, that party will be required to make additional 'variation
margin' payments equal to the change in value on a daily basis. The party that
has a gain may be entitled to
 
                                      -12-
 



<PAGE>
<PAGE>
receive all or a portion of this amount. The Portfolio may be obligated to make
payments of variation margin at a time when it is disadvantageous to do so.
Furthermore, it may not always be possible for the Portfolio to close out its
futures positions. Until it closes out a futures position, the Portfolio will be
obligated to continue to pay variation margin. Initial and variation margin
payments do not constitute purchasing on margin for purposes of the Portfolio's
investment restrictions. In the event of the bankruptcy of an FCM that holds
margin on behalf of the Portfolio, the Portfolio may be entitled to return of
margin owed to it only in proportion to the amount received by the FCM's other
customers, potentially resulting in losses to the Portfolio.
 
COVER -- SEGREGATED ACCOUNTS. The Portfolio will segregate liquid securities in
connection with its use of options and futures contracts to the extent required
by the SEC. Securities held in a segregated account cannot be sold while the
futures contract or option is outstanding, unless they are replaced with other
suitable assets. As a result, there is a possibility that the segregation of a
large percentage of the Portfolio's assets could impede portfolio management or
the Portfolio's ability to meet redemption requests or other current
obligations.
 
For further information about the Portfolio's use of futures and options and a
more detailed discussion of associated risks, see 'Investment Objectives and
Policies' in the SAI.
 
INVESTMENT RESTRICTIONS
 
The investment objective of the Fund and the Portfolio, together with the
investment restrictions described below and in the SAI, except as noted, are
deemed fundamental policies, i.e., they may be changed only by the 'vote of a
majority of the outstanding voting securities' (as defined in the Investment
Company Act of 1940 (the '1940 Act')), of the Fund or the Portfolio,
respectively. The Fund has the same investment restrictions as the Portfolio,
except that the Fund may invest all of its investable assets in another open-end
investment company with the same investment objective and restrictions (such as
the Portfolio). References below to the Portfolio's investment restrictions also
include the Fund's investment restrictions.
 
As a diversified investment company, 75% of the total assets of the Portfolio
are subject to the following fundamental limitations: (a) the Portfolio may not
invest more than 5% of its total assets in the securities of any one issuer,
except U.S. Government securities; and (b) the Portfolio may not own more than
10% of the outstanding voting securities of any one issuer.
 
The Portfolio may not: (i) purchase the securities or other obligations of
issuers conducting their principal business activity in the same industry if its
investments in such industry would exceed 25% of the value of the Portfolio's
total assets, except this limitation shall not apply to investments in U.S.
Government securities; (ii) enter into reverse repurchase agreements or other
permitted borrowings that constitute senior securities under the 1940 Act,
exceeding in the aggregate one-third of the value of the Portfolio's total
assets; or (iii) borrow money, except from banks for extraordinary or emergency
purposes, or mortgage, pledge or hypothecate any assets except in connection
with any such borrowings or permitted reverse repurchase agreements in amounts
up to one-third of the value of the Portfolio's total assets at the time of such
borrowing, or purchase securities while borrowings and other senior securities
exceed 5% of its total assets. For a more detailed discussion of the above
investment restrictions, as well as a description of certain other investment
restrictions, see 'Investment Restrictions' and 'Additional Information' in the
SAI.
 
MANAGEMENT
 
DIRECTORS AND TRUSTEES. Pursuant to the Trust's Declaration of Trust, the
Trustees of the Trust establish the Portfolio's general policies, are
responsible for the overall management of the Trust, and review the actions of
the Adviser, Sub-Adviser, Administrator and other service providers. Similarly,
the Directors of the Company set the Company's general policies, are responsible
for the overall management of the Company, and review the performance of its
service providers. Additional information about the Company's Board of Directors
and officers appears in the SAI under the heading 'Directors and Trustees'. The
Trustees of the Trust are also the Directors of the Company, which raises
certain conflicts of interest.
 
                                      -13-
 



<PAGE>
<PAGE>
The Company and the Trust have each adopted written procedures reasonably
designed to deal with these conflicts, should they arise. The officers of the
Company are also employees of Investors Bank or its affiliates.
 
ADVISER AND FUNDS SERVICES AGENT. The Company has not retained the services of
an investment adviser with respect to the Fund because the Fund seeks to achieve
its investment objective by investing all of its investable assets in the
Portfolio. The Portfolio has retained the services of the New York Branch (the
'Branch' or the 'Adviser') of Union Bank of Switzerland (the 'Bank') as
investment adviser and UBS Asset Management (New York) Inc. ('UBSAM') as
investment sub-adviser (the 'Sub-Adviser' and, together with the Branch, the
'Advisers'). The Branch, which operates out of offices located at 1345 Avenue of
the Americas, New York, New York, is licensed by the Superintendent of Banks of
the State of New York under the banking laws of the State of New York and is
subject to state and federal banking laws and regulations applicable to a
foreign bank that operates a state licensed branch in the United States. UBSAM,
which also operates out of offices located at 1345 Avenue of the Americas, New
York, New York, is a registered investment adviser in the U.S.
 
   
The Bank has branches, agencies, representative offices and subsidiaries in
Switzerland and in more than 40 cities outside Switzerland, including, in the
United States, New York City, Houston, Los Angeles and San Francisco. In
addition to the receipt of deposits and the making of loans and advances, the
Bank, through its offices and subsidiaries engages in a wide range of banking
and financial activities typical of the world's major international banks,
including fiduciary, investment advisory and custodial services and foreign
exchange in the United States, Swiss, Asian and Euro-capital markets. The Bank
is one of the world's leading asset managers and has been active in New York
City since 1946. At June 30, 1997, the Bank (including its consolidated
subsidiaries) had total assets of $352.1 billion (unaudited) and equity capital
and reserves of $16.2 billion (unaudited).
    
 
The Advisers provide investment advice and portfolio management to the
Portfolio. Subject to the supervision of the Trustees and the Adviser, the
Sub-Adviser makes the Portfolio's day-to-day investment decisions, arranges for
the execution of portfolio transactions and generally manages the Portfolio's
investments and operations. See 'Investment Adviser and Funds Services Agent' in
the SAI.
 
In addition to the above-listed investment advisory services, the Branch also
provides the Fund and the Portfolio with certain related administrative
services. Subject to the supervision of the Directors and Trustees,
respectively, the Branch is responsible for: establishing performance standards
for the third-party service providers of the Fund and Portfolio and overseeing
and evaluating the performance of such entities; providing and presenting
quarterly management reports to the Directors and the Trustees; supervising the
preparation of reports for Fund and Portfolio shareholders; and establishing
voluntary expense limitations for the Fund and providing any resultant expense
reimbursement to the Fund.
 
The Branch provides its administrative services to the Fund pursuant to a Funds
Services Agreement between the Branch and the Company. The Branch does not
receive a fee from the Company or the Fund pursuant to the terms of the Funds
Services Agreement.
 
Under the Trust's Investment Advisory Agreement, the Portfolio pays the Adviser
a fee, calculated daily and payable monthly, equal, on an annual basis, to 0.60%
of the Portfolio's average daily net assets. The Branch has voluntarily agreed
to waive its fees and reimburse the Fund and the Portfolio for any of their
respective direct and indirect expenses to the extent that the Fund's total
operating expenses (including its share of the Portfolio's expenses) exceed, on
an annual basis, 1.20% of the Fund's average daily net assets. The Branch may
modify or discontinue this fee waiver and expense limitation at any time in the
future with 30 days' prior notice to the Fund. See 'Expenses'.
 
   
SUB-ADVISER. The Sub-Adviser uses a sophisticated, disciplined, collaborative
process for managing the Portfolio. Paul A. Graham, Jr., CFA is primarily
responsible for the day-to-day management and implementation of the
Sub-Adviser's process for the Portfolio. Mr. Graham has twelve years investment
experience and has been a Vice President and Portfolio Manager of the
Sub-Adviser since 1994. Previously, Mr. Graham was affiliated with Value Line,
Inc. Mr. Graham received a BA from Dartmouth and is a member of the New York
Society of Security Analysts. The Sub-Adviser has advised mutual funds for only
a short time.
    
 
                                      -14-
 



<PAGE>
<PAGE>
   
Pursuant to the Sub-Advisory Agreement between the Adviser and the Sub-Adviser,
the Adviser has agreed to pay the Sub-Adviser a fee, calculated daily and
payable monthly equal, on an annual basis, to 0.40% of the first $25 million of
the Portfolio's average daily net assets plus 0.325% of the next $25 million of
such assets plus 0.25% on such assets in excess of $50 million. The Adviser is
solely responsible for paying the Sub-Adviser this fee.
    
 
INVESTMENTS IN THE FUND ARE NOT DEPOSITS WITH OR OBLIGATIONS OF, OR GUARANTEED
OR ENDORSED BY, THE BRANCH OR ANY OTHER BANK.
 
ADMINISTRATORS. The Fund and the Portfolio employ Investors Bank & Trust Company
('Investors Bank') and Investors Fund Services (Ireland) Limited ('IBT
Ireland'), a subsidiary of Investors Bank, respectively, as Administrators under
Administration Agreements (the 'Administration Agreements') to provide certain
administrative services. The services provided by Investors Bank and IBT Ireland
under the Administration Agreements include certain accounting, clerical and
bookkeeping services, Blue Sky (for the Fund only), corporate secretarial
services and assistance in the preparation and filing of tax returns and reports
to shareholders and the Securities and Exchange Commission ('SEC'). Investors
Bank is a wholly-owned subsidiary of Investors Financial Services Corp., a
publicly-held corporation and holding company registered under the Bank Holding
Company Act of 1956.
 
For its services under the Administration Agreement, the Fund has agreed to pay
Investors Bank a fee, calculated daily and payable monthly, equal, on an annual
basis, to 0.065% of the Fund's first $100 million of average daily net assets
and 0.025% of the next $100 million of average daily net assets. Investors Bank
does not receive a fee from the Fund on average daily net assets in excess of
$200 million.
 
Under the Trust's Administrative Services Agreement, the Portfolio has agreed to
pay IBT Ireland a fee, calculated daily and payable monthly, equal, on an annual
basis, to 0.07% of the Portfolio's first $100 million of average daily net
assets and 0.05% of average daily net assets in excess of $100 million. IBT
Ireland's principal offices are located at Deloitte & Touche House, 29 Earlsfort
Terrace, Dublin 2, Ireland. Investors Bank's principal offices are located at
200 Clarendon Street, Boston, Massachusetts 02116.
 
DISTRIBUTOR. Pursuant to a Distribution Agreement, First Fund Distributors, Inc.
(the 'Distributor') serves as the distributor of Fund shares. The Distributor is
a broker-dealer registered with the SEC and is a member of the National
Association of Securities Dealers, Inc. ('NASD'). The Distributor is authorized
by the NASD to act as a mutual fund underwriter and distributor. The principal
offices of the distributor are located at 4455 E. Camelback Road, Phoenix,
Arizona 85018. The Distributor does not receive a fee pursuant to the terms of
the Distribution Agreement, but receives compensation from Investors Bank.
 
CUSTODIAN. Investors Bank also serves as the custodian for the Portfolio and the
Fund and transfer and dividend disbursing agent for the Fund. See 'Custodian' in
the SAI. The Custodian also maintains offices at 1 First Canadian Place, Suite
2800, Toronto, Ontario M5X1C8.
 
SHAREHOLDER SERVICES
 
The Company has entered into a shareholder servicing agreement with the Branch,
and may enter into additional shareholder servicing agreements with one or more
financial institutions (together with the Branch, 'Eligible Institutions') such
as a federal or state-chartered bank, trust company, savings and loan
association or savings bank, or broker-dealer. Pursuant to each shareholder
servicing agreement, an Eligible Institution, as agent for its customers who are
purchasing shares of the Fund, will perform the following services for these
investors, among other things: coordinating shareholder accounts and records,
assisting investors seeking to purchase or redeem Fund shares, providing
performance information relating to the Fund, and responding to shareholder
inquiries. The Company has agreed to pay each Eligible Institution a fee for
these services equal, on an annual basis, to 0.25% of the average daily net
assets of the Fund represented by shares of the Fund owned during the period for
which payment is being made by customers of the Eligible Institution. Under the
terms of the shareholder servicing agreements, Eligible Institutions may
delegate one or more of their responsibilities to other entities at their
expense.

EXPENSES
 
In addition to the fees of the Branch, Investors Bank and IBT Ireland, the Fund
will be responsible for other expenses, including brokerage costs and litigation
and extraordinary expenses. The Branch has voluntarily agreed to limit the total
operating expenses of the Fund, excluding extraordinary expenses, to an annual
rate of 1.20% of the Fund's average daily net assets. The Branch may modify or
discontinue this voluntary expense limitation at any time in the future with 30
days' prior notice to the Fund.
 
The Fund and the Portfolio may allocate brokerage transactions to their
affiliates and the Adviser's affiliates only if the commissions received by such
affiliates are fair and reasonable when compared to the commissions paid to
unaffiliated brokers in connection with comparable transactions. See 'Portfolio
Transactions' in the SAI.
 
PURCHASE OF SHARES
 
GENERAL INFORMATION ON PURCHASES. Investors may purchase Fund shares only
through the Distributor. All purchase orders must be accepted by the
Distributor. The Fund also reserves the right to determine the purchase orders
that it will accept and reserves the right to cease offering its shares for a
period of time. The shares of the Fund may be purchased only in those states
where they may be lawfully sold.
 
The minimum initial investment in the Fund is $25,000, except that the minimum
initial investment is $10,000 for shareholders of another series of the Company.
The minimum subsequent investment in the Fund for all investors is $5,000. The
minimum initial investment for employees of the Bank or its affiliates is $5,000
and the minimum subsequent investment is $1,000. These minimum investment
requirements may be waived at the Fund's sole discretion.
 
No share certificates will be issued.
 
PURCHASE PRICE AND SETTLEMENT. The shares of the Fund are sold on a continuous
basis without a sales charge at the net asset value per share next determined
after receipt and acceptance of a purchase order by the Distributor. The Fund
calculates its net asset value at the close of business on any day on which the
New York Stock Exchange (the 'NYSE') is open for regular trading (a 'Fund
Business Day'). Purchase orders received and accepted by the Distributor prior
to 4:00 p.m. New York time on any Fund Business Day will be effective and is
executed at the net asset value determined that day. The purchaser becomes a
holder of record that day, provided the Fund receives payment for those shares
on the following business day ('settlement date') and as a recordholder is
entitled to earn dividends. Purchase orders received after 4:00 p.m. will
receive the net asset value determined on the next Fund Business Day, and the
investor becomes a holder of record on the business day following the Fund's
receipt of payment. Investors will receive the number of full and fractional
shares of the Fund equal to the dollar amount of their subscription divided by
the net asset value per share of the Fund next determined on the day that the
investor's purchase is accepted. See also 'Purchase of Shares' in the Statement
of Additional Information.
 
Customers of Eligible Institutions should request a representative of their
Eligible Institution to assist them in placing a purchase order with the
Distributor. Shareholders who do not currently maintain a relationship with an
Eligible Institution may purchase shares of the Fund directly from the
Distributor by wire transfer or mail.
 
By wire transfer: Purchases may be made by federal funds wire. To place a
purchase order with the Fund, the shareholder must telephone the Transfer Agent
at (888) UBS-FUND (888-827-3863). A completed account application must promptly
follow any wire order for an initial purchase. Completed account applications
should be mailed or sent via facsimile. Investors should contact the Transfer
Agent for further instructions regarding account applications. Account
applications are not required for subsequent purchases; however, the investor's
account number must be clearly indicated on the wire to ensure proper credit.

Investors Bank & Trust Company; P.O. Box 9130; MFD 23; Boston, Massachusetts
02117-9130.
 
Checks are subject to collection at full value. For shares purchased by check,
dividend payments and redemption proceeds, if any, will be delayed until such
funds are collected, which may take up to 15 days from the date of purchase. The
Fund will not accept third-party checks.
 
The Transfer Agent will maintain the accounts for all shareholders of record.
For account balance information and shareholder services, shareholders should
contact the Transfer Agent at (888) UBS-FUND (888-827-3863) or in writing to UBS
Private Investor Funds, Inc.; c/o Investors Bank & Trust Company; P.O. Box 9130;
MFD 23; Boston, MA 02117-9130.
 
REDEMPTION OF SHARES
 
GENERAL INFORMATION ON REDEMPTIONS. A shareholder may redeem all or any number
of the shares registered in its name at any time at the net asset value next
determined after a redemption request in proper form is received by the
Distributor. To be in proper form, the Fund must have received the shareholders
taxpayer identification number and address. Redemption requests must include the
name of the Fund, the dollar amount or number of shares to be redeemed and the
shareholder's account number. The request must be signed by a person who is
authorized to transact on behalf of the shareholder. In all cases, all
signatures on a redemption request must be signature guaranteed by an eligible
guarantor institution which includes a domestic bank, a domestic savings and
loan institution, a domestic credit union, a member bank of the Federal Reserve
System or a member firm of a national securities exchange, pursuant to the
Fund's standards and procedures. If the guarantor institution belongs to one of
the Medallion Signature programs, it must use the specific 'Medallion
Guaranteed' stamp. Guarantees by notaries public are not acceptable. Further
documentation, such as copies of corporate resolutions and instruments of
authority may be requested from corporations, administrators, executors,
personal representatives, trustees or custodians to evidence the authority of
the person or entity making the redemption request.
 
Customers of Eligible Institutions must request a representative of their
Eligible Institution to assist them in placing a redemption order with the Fund.
 
REDEMPTION PRICE AND SETTLEMENT. Redemption orders received by the Distributor
in good form prior to 4:00 p.m. New York time on any Fund Business Day will be
effected and executed at the net asset value determined on that day. Redemption
orders received after 4:00 p.m. New York time will be effected and executed at
the net asset value determined on the next Fund Business Day. Proceeds from the
redemption will be generally deposited the next business day in immediately
available funds to the account designated by the redeeming shareholder, or sent
by check to the address of record if requested by the shareholder.
 
Shareholders will continue to earn dividends through the day of redemption.
 
Shareholders who maintain an account directly with the Distributor may redeem
Fund shares by mail or telephone.
 
By mail: Redemption requests may be mailed to the Transfer Agent, identifying
the Fund, the dollar amount or number of shares to be redeemed and the
shareholder's account number. The request must be
 
                                      -17-
 



<PAGE>
<PAGE>
signed in exactly the same manner as the account is registered (e.g., if there
is more than one owner of the shares, all must sign). In all cases, a signature
guarantee is required. See 'General Information on Redemptions' above.
 
By telephone: The shareholder may place a redemption request by calling the
Transfer Agent at 888-UBS-FUND (888-827-3863). Shareholders utilizing the
telephone redemption option must have previously designated this option on the
initial account application, or by subsequent written authorization to the Fund.
Such shareholders risk possible loss of principal and income in the event of a
telephone redemption not authorized by them. The Fund and the Transfer Agent
will employ reasonable procedures to verify that telephone redemption
instructions are genuine and will require that shareholders electing such an
option provide a form of personal identification. The failure by the Fund or the
Transfer Agent to employ such procedures may cause the Fund or the Transfer
Agent to be liable for any losses incurred by investors due to telephone
redemptions based upon unauthorized or fraudulent instructions. The telephone
redemption option may be modified or discontinued at any time upon 60 days'
notice to shareholders.
 
MANDATORY REDEMPTION. If the value of a shareholder's holdings in the Fund falls
below $10,000 because of a redemption of shares, the shareholder's remaining
shares may be redeemed 60 days after written notice unless the account is
increased to $10,000 or more. For example, a shareholder whose initial and only
investment is $10,000 may be subject to mandatory redemption resulting from any
redemption that causes his or her investment to fall below $10,000.
 
FURTHER REDEMPTION INFORMATION. Investors should be aware that redemptions may
not be processed unless the redemption request is submitted in proper form. To
be in proper form, the Fund must have received the shareholder's taxpayer
identification number and address. As discussed under 'Taxes' below, the Fund
may be required to impose 'back-up' withholding of federal income tax on
dividends, distributions and redemptions when non-corporate investors have not
provided a certified taxpayer identification number. In addition, if an investor
sends a check to the Distributor for the purchase of Fund shares and shares are
purchased with funds made available by the Distributor before the check has
cleared, the transmittal of redemption proceeds from the sale of those shares
will not occur until the check used to purchase such shares has cleared, which
may take up to 15 days. Redemption delays may be avoided by purchasing shares by
federal funds wire.
 
The right of redemption may be suspended or the date of payment postponed for
such periods as the 1940 Act or the SEC may permit. See 'Redemption of Shares'
in the SAI.
 
EXCHANGE OF SHARES
 
An investor may exchange Fund shares for shares of any other series of the
Company, without charge. An exchange may be made so long as after the exchange
the investor has shares, in each series in which it remains an investor, with a
value equal to or greater than each such series' minimum investment amount. See
'Purchase of Shares' in the prospectuses of the other Company series for the
minimum investment amounts for each of those funds. Shares are exchanged on the
basis of relative net asset value per share. Exchanges are in effect redemptions
from one fund and purchases of another fund and the usual purchase and
redemption procedures and requirements are applicable to exchanges. See
appropriate section relating to the purchase and redemption of shares in this
and other prospectuses. See also 'Additional Information' below for an
explanation of the telephone exchange policy.
 
Shareholders subject to federal income tax who exchange shares in one fund for
shares in another fund may recognize capital gain or loss for federal income tax
purposes. The Fund reserves the right to discontinue, alter or limit its
exchange privilege at any time. For investors in certain states, state
securities laws may restrict the availability of the exchange privilege.
 
RETIREMENT PLANS
 
The Fund has available a form of Individual Retirement Account ('IRA') for
investment in Fund shares. Subject to certain restrictions imposed by applicable
tax laws, self-employed individuals may purchase shares of the Fund through
tax-deductible contributions to existing retirement plans known as Self-Employed
Retirement Plans ('SERPs'). Fund shares may also be a suitable investment for
'401(k) Plans'
 
                                      -18-
 



<PAGE>
<PAGE>
which subject to certain restrictions allow their participants to invest in
qualified pension plans on a tax-deferred basis. The Fund does not currently act
as sponsor to such plans.
 
The minimum initial investment for all such retirement plans is $2,000. The
minimum for all subsequent investments is $500.
 
Under the Internal Revenue Code of 1986, as amended (the 'Tax Code'),
individuals may make IRA contributions of up to $2,000 annually, which may be,
depending on the contributor's participation in an employer-sponsored plan and
income level, wholly or partly tax-deductible. However, dividends and
distributions held in the account are not taxed until withdrawn in accordance
with the provisions of the Tax Code. An individual with a non-working spouse may
establish a separate IRA for the spouse under the same conditions and contribute
a combined maximum of $4,000 annually to one or both IRAs provided that no more
than $2,000 may be contributed to the IRA of either spouse.
 
Investors should be aware that they may be subject to penalties or additional
taxes on contributions to or withdrawals from IRAs or other retirement plans
under certain circumstances. Prior to a withdrawal, shareholders may be required
to certify as to their age and awareness of such restrictions in writing.
Clients of Eligible Institutions desiring information concerning investments
through IRAs or other retirement plans should contact their Eligible
Institution. Clients who do not maintain a relationship with an Eligible
Institution may obtain such information by calling the Transfer Agent at (888)
UBS-FUND.
 
DIVIDENDS AND DISTRIBUTIONS
 
Dividends consisting of substantially all of the Fund's net investment income,
if any, are declared and paid annually. The Fund may also declare an additional
dividend of net investment income in a given year to the extent necessary to
avoid the imposition of federal excise taxes on the Fund.
 
Substantially all of the Fund's realized net capital gains, if any, will be
declared and paid on an annual basis, except that an additional capital gains
distribution may be made in a given year to the extent necessary to avoid the
imposition of federal excise taxes on the Fund. Declared dividends and
distributions are payable on the payment date to shareholders of record on the
record date.
 
Dividends and capital gains distributions paid by the Fund are automatically
reinvested in additional Fund shares unless the shareholder has elected, in
writing, to have them paid in cash. Dividends and distributions to be paid in
cash are credited to the account designated by the shareholder or sent by check
to the shareholder's address of record, in accordance with the shareholder's
instructions. The Fund reserves the right to discontinue, alter or limit the
automatic reinvestment privilege at any time.
 
NET ASSET VALUE
 
The Fund's net asset value per share equals the value of the Fund's total assets
(i.e., the value of its investment in the Portfolio plus its other assets) less
the amount of its liabilities, divided by the number of its outstanding shares,
rounded to the nearest cent. Expenses, including the fees payable to the service
providers of the Fund and the Portfolio, are accrued daily. Securities for which
market quotations are readily available are valued at market value. All other
securities will be valued at 'fair value'. See 'Net Asset Value' in the SAI for
information on the valuation of the Portfolio's assets and liabilities.
 
The Fund computes its net asset value once daily at the close of business on
Monday through Friday, except that the net asset value is not computed for the
Fund on a day in which no orders to purchase or redeem Fund shares have been
received or on any day on which the New York Stock Exchange is closed, including
the following holidays: New Year's Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. On days
when U.S. trading markets close early in observance of these holidays, the Fund
expects to close for purchases and redemptions at the same time.

ORGANIZATION
 
UBS PRIVATE INVESTOR FUNDS, INC.
 
UBS Private Investor Funds, Inc., a Maryland corporation incorporated on
November 16, 1995, is an open-end management investment company registered under
the 1940 Act and organized as a series fund. The Company is currently authorized
to issue shares in eight series: The UBS Bond Fund Series; The UBS Tax Exempt
Bond Fund Series; The UBS High Yield Bond Fund Series; The UBS International
Equity Fund Series; The UBS Institutional International Equity Fund Series; The
UBS U.S. Equity Fund Series; The UBS Large Cap Growth Fund Series; and The UBS
Small Cap Fund Series. Each outstanding share of the Company will have a pro
rata interest in the assets of its series, but it will have no interest in the
assets of any other Company series. Only shares of The UBS Small Cap Fund Series
are offered through this Prospectus.
 
Shareholder inquiries by clients of Eligible Institutions may be directed to
their Eligible Institution and other shareholders may address their inquiries to
the Transfer Agent.
 
Shareholders of the Fund are entitled to one vote for each share and to the
appropriate fractional vote for each fractional share. There is no cumulative
voting. Shares have no preemptive or conversion rights. Shares are fully paid
and nonassessable when issued by the Company. The Company does not intend to
hold meetings of shareholders annually. The Directors may call meetings of
shareholders for action by shareholder vote as may be required by its Articles
of Incorporation or the 1940 Act. For further organizational information,
including certain shareholder rights, see 'Organization' in the SAI.
 
UBS INVESTOR PORTFOLIOS TRUST
 
UBS Investor Portfolios Trust, a master trust fund formed under New York law,
was organized on February 9, 1996. The Declaration of Trust permits the Trustees
to issue interests divided into one or more subtrusts or series. To date, seven
series have been authorized, of which UBS Small Cap Portfolio is one.
 
The Declaration of Trust provides that no Trustee, shareholder, officer,
employee, or agent of the Trust shall be held to any personal liability, nor
shall resort be had to such person's private property for the satisfaction of
any obligation or claim or otherwise in connection with the affairs of the
Portfolio, but that only the Trust property shall be liable.
 
The Declaration of Trust provides that the Fund and other entities investing in
the Portfolio (e.g., other investment companies, insurance company separate
accounts and common and commingled trust funds) will each be liable for all the
obligations of the Portfolio. However, the risk of the Fund's incurring
financial loss on account of such liability is limited to circumstances in which
both inadequate insurance existed and the Portfolio itself was unable to meet
its obligations. Accordingly, the Trustees believe that neither the Fund nor its
shareholders will be adversely affected by reason of the Fund's investment in
the Portfolio.
 
TAXES
 
The Fund intends to qualify as a regulated investment company (a 'RIC') under
Subchapter M of the Tax Code. As a RIC, a Fund (as opposed to its shareholders)
will not be subject to federal income taxes on the net investment income and
capital gains that it distributes to its shareholders, provided that at least
90% of its net investment income and realized net short-term capital gains in
excess of net long-term capital losses for the taxable year is distributed. The
Portfolio intends to qualify as a partnership for federal income tax purposes.
As such, the Portfolio generally should not be subject to tax. The status of the
Fund as a regulated investment company is dependent on, among other things, the
Portfolio's continued qualification as a partnership for federal income tax
purposes.
 
Dividends from net investment income and distributions from realized net
short-term capital gains in excess of net long-term capital losses are taxable
as ordinary income to Fund shareholders whether such distributions are received
in the form of cash or reinvested in additional shares. To the extent that
dividends distributed to shareholders are designated as derived from the Fund's
dividend income that
 
                                      -20-
 



<PAGE>
<PAGE>
would be eligible for the dividends received deduction if the Fund were not a
regulated investment company, such dividends are eligible, subject to certain
restrictions, for the 70% dividends received deduction for corporations.
Distributions of net long-term capital gains in excess of net short-term capital
losses are taxable to Fund shareholders as long-term capital gains regardless of
how long a shareholder has held shares in the Fund and regardless of whether
received in the form of cash or reinvested in additional shares. Long-term
capital gains distributions to corporate shareholders are not eligible for the
dividends-received deduction. Annual statements as to the current federal tax
status of distributions will be mailed to shareholders after the end of the
taxable year for the Fund.
 
Any gain or loss realized on the redemption or exchange of Fund shares by a
shareholder who is not a dealer in securities generally will be treated as
long-term capital gain or loss if the shares have been held for more than one
year, and otherwise as short-term capital gain or loss. However, any loss
realized by a shareholder upon the redemption or exchange of shares in the Fund
held for six months or less will be treated as a long-term capital loss to the
extent of any long-term capital gain distributions received by the shareholder
with respect to such shares. In addition, no loss will be allowed on the sale or
other disposition of shares of the Fund if, and to the extent that, within a
period beginning 30 days before the date of such sale or disposition and ending
30 days after such date, the holder acquires (such as through dividend
reinvestment) securities that are substantially identical to the shares of the
Fund.
 
The Fund will generally be subject to an excise tax of 4% on the amount of any
income or capital gains, above certain permitted levels, distributed to
shareholders on a basis such that such income or gain is not taxable to
shareholders in the calendar year in which it was earned by the Fund.
Furthermore, dividends declared in October, November, or December payable to
shareholders of record on a specified date in such a month and paid in the
following January will be treated as having been paid by the Fund and received
by each shareholder in December. Under this rule, therefore, shareholders may be
taxed in one year on dividends or distributions actually received in January of
the following year.
 
Distributions of net investment income or net long-term capital gains will have
the effect of reducing the net asset value of the Fund's shares by the amount of
the distribution. If the net asset value is reduced below a shareholder's cost,
the distribution will nonetheless be taxable as described above, even if the
distribution represents a return of invested capital. Investors should consider
the tax implications of buying shares just prior to a distribution, when the
price of shares may reflect the amount of the forthcoming distribution.
 
If a correct and certified taxpayer identification number is not on file, the
Fund is required, subject to certain exemptions, to withhold 31% of certain
payments made or distributions declared to non-corporate shareholders.
Shareholders should be aware that, under applicable regulations, the Fund may be
fined up to $50 annually for each account for which a certified taxpayer
identification number is not provided. In the event that such a fine is imposed
with respect to any uncertified account in any year, a corresponding charge may
be made against that account.
 
This discussion of tax consequences is based on U.S. federal tax laws in effect
on the date of this Prospectus. These laws and regulations are subject to change
by legislative or administrative action, possibly with retroactive effect.
Investors are urged to consult their own tax advisors with respect to specific
questions as to federal taxes and with respect to the applicability of state or
local taxes. See 'Taxes' in the SAI.
 
ADDITIONAL INFORMATION
 
The Fund will send its shareholders annual and semi-annual reports. The
financial statements appearing in annual reports will be audited by independent
accountants. Shareholders also will be sent confirmations of each purchase and
redemption and periodic statements reflecting all account activity, including
dividends and any distributions whether reinvested in additional shares or paid
in cash.
 
Shareholders of certain Eligible Institutions may be given the privilege to
initiate transactions automatically by telephone upon opening an account.
However, an investor should be aware that a transaction authorized by telephone
and reasonably believed to be genuine by the Company, the Branch, the Eligible
Institution, the Transfer Agent or the Distributor may subject the investor to
risk of loss if
 
                                      -21-
 



<PAGE>
<PAGE>
such instruction is subsequently found not to be genuine. The Company and its
service providers will employ reasonable procedures, including requiring
investors to give a form of personal identification and tape recording of
telephonic instructions, to confirm that telephonic instructions by investors
are genuine; if it does not, it or the service provider may be liable for any
losses due to unauthorized or fraudulent instructions.
 
The Fund may make historical performance information available and may compare
its performance to other investments or relevant indices, including data from
Lipper Analytical Services, Inc., Micropal Inc., Morningstar Inc., Ibbotson
Associates, S&P 500 Index, the Dow Jones Average, the Frank Russell Indices, the
Financial Times World Stock Index and other industry publications.
 
The Fund may advertise 'total return'. The total return shows what an investment
in the Fund would have earned over a specified period of time (one, five or ten
years or since commencement of operations, if less) assuming that all Fund
distributions and dividends were reinvested on the reinvestment dates and less
all recurring fees during the period and assuming the redemption of such
investment at the end of each period. This method of calculating total return is
required by regulations of the SEC. Total return data similarly calculated,
unless otherwise indicated, over other specified periods of time may also be
used. All performance figures are based on historical earnings and are not
intended to indicate future performance. Performance information may be obtained
by clients of an Eligible Institution by calling the Eligible Institution and
other shareholders may address their inquiries to the Transfer Agent.

FOR INFORMATION CALL (888) UBS-FUND ((888) 827-3863)
 
   
UBS Large Cap Growth Fund (the 'Fund') seeks to provide long-term capital
appreciation. In order to accomplish this, the Sub-Adviser (defined below)
intends to invest primarily in a diversified portfolio of common stocks and
other equity securities of companies that at the time of purchase have market
capitalizations that are within the market capitalization range of those stocks
listed on the Standard & Poor's 500 ('S&P 500') Index and that the Sub-Adviser
believes will have above-average earnings and cash flow growth or meaningful
increases in underlying asset values over time. There is no assurance that the
Fund will achieve its stated objective.
    
 
The Fund is a diversified, no-load mutual fund for which there are no sales
charges or exchange or redemption fees. The Fund is one of several series of UBS
Private Investor Funds, Inc. (the 'Company'), an open-end management investment
company organized as a corporation under Maryland law.
 
UNLIKE OTHER MUTUAL FUNDS THAT DIRECTLY ACQUIRE AND MANAGE THEIR OWN PORTFOLIO
OF SECURITIES, THE FUND SEEKS TO ACHIEVE ITS INVESTMENT OBJECTIVE BY INVESTING
ALL OF ITS INVESTABLE ASSETS IN UBS LARGE CAP GROWTH PORTFOLIO (THE
'PORTFOLIO'). THE PORTFOLIO IS A SERIES OF UBS INVESTOR PORTFOLIOS TRUST, (THE
'TRUST'), AN OPEN-END MANAGEMENT INVESTMENT COMPANY. THE PORTFOLIO HAS THE SAME
INVESTMENT OBJECTIVE AS THE FUND. THE FUND EMPLOYS A TWO-TIER MASTER-FEEDER
INVESTMENT FUND STRUCTURE THAT IS MORE FULLY DESCRIBED UNDER THE SECTION
CAPTIONED 'MASTER-FEEDER STRUCTURE'.
 
The Portfolio is advised by the New York Branch (the 'Branch' or the 'Adviser')
of Union Bank of Switzerland (the 'Bank') and UBS Asset Management (New York)
Inc. (the 'Sub-Adviser' and, together with the Adviser, the 'Advisers').
 
   
This Prospectus sets forth concisely the information about the Fund that a
prospective investor ought to know before investing. It should be read and
retained for future reference. A Statement of Additional Information, dated
September 8, 1997 (the 'SAI'), provides further discussion of certain topics
referred to in this Prospectus and other matters that may be of interest to
investors. The SAI has been filed with the Securities and Exchange Commission,
is incorporated herein by reference, and is available without charge upon
written request from the Company or Distributor (as defined herein) at the
addresses set forth on the back cover of the Prospectus, or by calling (888)

OR ENDORSED BY, UNION BANK OF SWITZERLAND OR ANY OTHER BANK. SHARES OF THE FUND
ARE NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL

UBS LARGE CAP GROWTH FUND
INVESTORS FOR WHOM THE FUND IS DESIGNED
 
UBS Large Cap Growth Fund (the 'Fund') is designed for investors seeking
long-term capital appreciation. Because of the risks associated with common
stock investments, the Fund is intended to be a long-term investment vehicle and
is not intended to provide investors with a means for speculating on short-term
market movements. The Fund seeks to achieve its investment objective by
investing all of its investable assets in UBS Large Cap Growth Portfolio (the
'Portfolio'). The Portfolio is a series of UBS Investor Portfolios Trust (the
'Trust'), an open-end management investment company. The Portfolio has the same
investment objective as the Fund. Because the investment characteristics and
experience of the Fund will correspond directly with those of the Portfolio, the
discussion in this Prospectus focuses on the investments and investment policies
of the Portfolio. The net asset value of shares of the Fund fluctuates with
changes in the value of the investments in the Portfolio.
 
   
The Portfolio may make various types of investments in seeking its objective.
Among the permissible investments for the Portfolio are equity securities of
domestic issuers with market capitalizations at the time of purchase by the
Portfolio that are within the market capitalization range of those stocks listed
on the S&P 500 Index. Equity securities includes common stocks and securities
which are convertible into common stocks. The Portfolio may also invest in
futures contracts, options and certain privately placed securities. For further
information about these investments and related investment techniques, see
'Investment Objective and Policies' discussed below.
    
 
The minimum initial investment in the Fund is $25,000, except that the minimum
initial investment is $10,000 for shareholders of another series of UBS Private
Investor Funds, Inc. (the 'Company'). The minimum subsequent investment for all
investors is $5,000. These minimums may be waived at the Fund's discretion. See
'Purchase of Shares'. If shareholders reduce their total investment in shares of
the Fund to less than $10,000, their investment will be subject to mandatory
redemption. See 'Redemption of Shares -- Mandatory Redemption'. The Fund is one
of several series of the Company, an open-end management investment company
organized as a Maryland corporation.
 
This Prospectus describes the investment objective and policies, management and
operations of the Fund to enable investors to decide if the Fund suits their
investment needs. The Fund operates through a two-tier master-feeder investment
fund structure. The Company's Board of Directors (the 'Directors' or the
'Board') believes that this structure provides Fund shareholders with the
opportunity to achieve certain economies of scale that would otherwise be
unavailable if the shareholders' investments were not pooled with other
investors sharing similar investment objectives.
 
The following table illustrates that investors in the Fund incur no shareholder
transaction expenses: their investments in the Fund are subject only to the
operating expenses set forth below for the Fund and the Portfolio, as a
percentage of average daily net assets of the Fund. The Directors believe that
the aggregate per share expenses of the Fund and the Portfolio will be
approximately equal to and may be less than the expenses that the Fund would
incur if it retained the services of an investment adviser and invested its
assets directly in portfolio securities. Fund and Portfolio expenses are
discussed below under the headings 'Management', 'Expenses' and 'Shareholder
Services'.

</TABLE>
 
*   Expenses are expressed as a percentage of the Fund's projected average daily
net assets and are based on the annualized estimates of expenses expected to be
incurred during the fiscal period ending December 31, 1997, after any applicable
fee waivers and expense reimbursements. Without such fee waivers and expense
reimbursements, Total Operating Expenses are estimated to equal, on an annual
basis, to 1.76% of the Fund's projected average daily net assets. See
'Management'.
 
**  The New York Branch (the 'Branch' or the 'Adviser') of Union Bank of
Switzerland (the 'Bank') has agreed to waive fees and reimburse each of the Fund
and the Portfolio for any of their respective operating expenses to the extent
that the Fund's total operating expenses (including its share of the Portfolio's
expenses) exceed, on an annual basis, 1.00% of the Fund's average daily net
assets. The Branch may modify or discontinue this undertaking at any time in the
future with 30 days' prior notice to the Fund. The Portfolio's advisory fee
would be equal, on an annual basis, to 0.60% of the average daily net assets of
the Portfolio if there were no fee waiver in effect. See 'Management -- Adviser
and Funds Services Agent' and 'Expenses'.
 
*** The fees and expenses in Other Expenses include fees payable to:
     (i)  Investors Bank & Trust Company ('Investors Bank', the 'Custodian', or
the 'Transfer Agent') (a) under an Administration Agreeement with the Fund, (b)
     as custodian of the Fund and the Portfolio and (c) as transfer agent of the
     Fund,
 
(ii)  Investors Fund Services (Ireland) Limited ('IBT Ireland') under an
Administration Agreement with the Portfolio, and
 
(iii) Eligible Institutions providing shareholder services under various
shareholder servicing agreements.
 
For a more detailed description of contractual fee arrangements, including fee
waivers and expense reimbursements, and of the fees and expenses included in
Other Expenses, see 'Management' and 'Shareholder Services'.
 
EXAMPLE
 
An investor would pay the following expenses on a $1,000 investment, assuming a
5% annual return and redemption at the end of each time period:

The above Expense Table is designed to assist investors in understanding the
various direct and indirect costs and expenses that Fund investors are expected
to bear and reflects the expenses of the Fund and the Fund's share of the
Portfolio's expenses. In connection with the above Example, please note that
$1,000 is less than the Fund's minimum investment requirement and that there are
no redemption or exchange fees of any kind. See 'Purchase of Shares', 'Exchange
of Shares' and 'Redemption of Shares'. THE EXAMPLE IS HYPOTHETICAL; IT IS
INCLUDED SOLELY FOR ILLUSTRATIVE PURPOSES, AND ASSUMES THE CONTINUATION OF THE
FEE WAIVERS AND EXPENSE REIMBURSEMENTS REPRESENTED IN THE ABOVE 'EXPENSE TABLE'.
IT SHOULD NOT BE CONSIDERED A REPRESENTATION OF FUTURE PERFORMANCE; ACTUAL
EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN.
 
   
HISTORICAL PERFORMANCE OF COMPARABLE DISCRETIONARY ACCOUNTS. The following table
sets forth (i) the composite average annual total return for the one, three,
five and ten year periods ended June 30, 1997 for all discretionary accounts
described below that have been managed for at least one full quarter by UBS
Asset Management (New York) Inc., a wholly-owned subsidiary of the Bank
('UBSAM'), and (ii) the
    
 
                                      -3-
 



<PAGE>
<PAGE>
   
average annual total return during the same periods for the S&P 500 Index (the
'Index'). The discretionary accounts described in (i) above have substantially
the same investment objective and policies and are managed in a manner
substantially the same as the Portfolio. The composite total return for such
accounts has been adjusted to deduct all of the Fund's annual total operating
expenses of 1.00% of average daily net assets as set forth in the Fee Table
above. The composite total return is time-weighted and weighted by individual
account size and reflects the reinvestment of dividends and interest. The
discretionary accounts are not subject to certain investment limitations,
diversification requirements and other restrictions imposed by federal
securities and tax laws on the Portfolio that, if applied to the accounts, may
have adversely affected their performance results. The composite total return of
these discretionary accounts does not represent the historical performance of
the Portfolio and should not be viewed as a prediction of future performance of

is a common measure of the performance of the U.S. stock market. The total
returns of the Index do not include management fees or commissions.

MASTER-FEEDER STRUCTURE
 
Unlike other mutual funds that directly acquire and manage their own portfolio
of securities, the Fund seeks to achieve its investment objective by investing
all of its investable assets in the Portfolio, a separate investment company
with the same investment objective as the Fund. The investment objective of the
Fund and the Portfolio may be changed only with the approval of the holders of a
majority of the outstanding voting securities of the Fund or a majority of the
investors in the Portfolio, respectively, after 30 days' prior notice.
 
This master-feeder structure has been developed relatively recently, so
shareholders should carefully consider this investment approach.
 
In addition to selling an interest in the Portfolio to the Fund, the Portfolio
may sell interests in the Portfolio to other mutual funds or institutional
investors. Such investors will invest in the Portfolio on the same terms and
conditions as the Fund and will incur a proportionate share of the Portfolio's
expenses. However, other entities investing in the Portfolio may sell shares of
their own fund using a different pricing structure than the Fund's. Such
different pricing structures may result in differences in returns experienced by
investors in other funds that invest in the Portfolio. Such differences in
returns are not uncommon and are present in other mutual fund structures.
Information concerning other holders of interests in the Portfolio is available
from Investors Bank at (888) UBS-FUND.
 
The Fund may withdraw its investment in the Portfolio at any time if the Board
determines that it is in the Fund's best interest to do so. Upon any such
withdrawal, the Board would consider what action might be taken, including the
investment of all the Fund's assets in another pooled investment entity having
the same investment objective and restrictions as the Fund or the retaining of
an investment adviser to manage the Fund's assets in accordance with the
investment policies described below with respect to the Portfolio.
 
Certain changes in the Portfolio's investment objective, policies or
restrictions, or a failure by the Fund's shareholders to approve a change in the
Portfolio's investment objective or restrictions, may require the Fund to
withdraw its investments in the Portfolio. Any such withdrawal could result in
an in-kind distribution of portfolio securities (as opposed to a cash
distribution) by the Portfolio to the Fund. Such a distribution may result in
the Fund's having a less diversified portfolio of investments or adversely
affect the Fund's liquidity, and the Fund could incur brokerage, tax or other
charges in converting such
 
                                      -4-
 



<PAGE>
<PAGE>
securities to cash. Notwithstanding the above, there are other means for meeting
shareholder redemption requests, such as borrowing.
 
Smaller funds investing in the Portfolio may be materially affected by the
actions of larger funds investing in the Portfolio. For example, if a large fund
withdraws from the Portfolio, the remaining funds may subsequently experience
higher pro rata operating expenses, thereby lowering returns. Additionally,
because the Portfolio would become smaller, it may become less diversified,
resulting in potentially increased portfolio risk (however, these possibilities
also exist for traditionally structured funds that have large or institutional
investors who may withdraw from a fund). Also, funds with a greater pro rata
ownership in the Portfolio could have effective voting control of its
operations. Except as permitted by the Securities and Exchange Commission (the
'SEC'), whenever the Fund is requested to vote on matters pertaining to the
Portfolio, the Company will hold a meeting of Fund shareholders and will cast
all of its votes proportionately as instructed by the Fund's shareholders. See
'Organization' in the SAI. Fund shareholders who do not vote will not affect the
Fund's votes at the Portfolio meeting. The percentage of the Company's votes
representing Fund shareholders not voting will be voted by the Company in the
same proportion as the Fund shareholders who do, in fact, vote.
 
For more information about the Portfolio's investment objective, policies and
restrictions, see 'Investment Objective and Policies', 'Additional Investment
Information and Risk Factors' and 'Investment Restrictions'. For more
information about the Portfolio's management and expenses, see 'Management'. For
more information about changing the investment objective, policies and
restrictions of the Fund or the Portfolio, see 'Investment Restrictions'.
 
INVESTMENT OBJECTIVE AND POLICIES
 
The investment objective of the Fund and the Portfolio is described below,
together with the policies each employs to seek to achieve its objective.
Additional information about the investment policies of the Fund and the
Portfolio appears in the SAI under 'Investment Objectives and Policies'. The
Fund seeks to achieve its investment objective by investing all of its
investable assets in the Portfolio, which has the same investment objective as
the Fund. There can be no assurance that the investment objective of the Fund or
the Portfolio will be achieved.
 
The Adviser is responsible for supervising the management of the Portfolio's
investment. Consistent with these duties, the Adviser has entered into a
Sub-Advisory Agreement with UBSAM (the 'Sub-Adviser' and, together with the
Adviser, the 'Advisers' ), whereby the Sub-Adviser is primarily responsible for
the day-to-day investment decisions for the Portfolio. The Adviser is solely
responsible for paying the Sub-Adviser for these services. The Sub-Adviser is an
affiliate of the Adviser.
 
   
The Portfolio's objective is to provide long-term capital appreciation. In order
to accomplish this, the Portfolio intends to invest primarily in a diversified
portfolio of common stocks, preferred stocks and other securities (such as
warrants and rights) that are either convertible into or exchangeable for common
stocks of large capital growth companies. The Portfolio defines 'large capital'
companies as companies whose market capitalizations at the time of acquisition
by the Portfolio are within the market capitalization range of those stocks
listed on the S&P 500 Index. Additionally, the Portfolio will not invest more
than 20% of its net assets in securities of companies whose market
capitalization is less than $3 billion. 'Growth' companies generally include
companies which have, in the Sub-Adviser's judgment, the prospects for
above-average earnings and cash flow growth or meaningful increases in
underlying asset values over time.
    
 
   
The Portfolio may also invest up to 20% of its assets in foreign securities,
including American Depository Receipts ('ADRs'), which the Sub-Adviser believes
meet the Portfolio's investment objective and relevant policies. See 'Foreign
Investment Information' and 'Foreign Currency Exchange Transactions' under
'Additional Investment Information and Risk Factors'.
    
 
Under normal circumstances, the Portfolio will invest at least 65% of its assets
in large capital growth companies. The Portfolio will invest in companies
believed by the Sub-Adviser to represent above average growth opportunities. The
Sub-Adviser will select individual securities for investment by screening for
above average earnings growth expectations and reasonable valuations (price
relative to earnings and cash
 
                                      -5-
 



<PAGE>
<PAGE>
flow). Growth company securities may have above average price volatility. The
Portfolio attempts to reduce its overall exposure to the risk of declines in
individual security prices by diversifying its investments over a carefully
selected list of securities issued by different companies in a variety of
industries.
 
Although the Portfolio intends to invest primarily in equity securities, under
normal market conditions it may invest up to 20% of its assets in certain cash
investments and certain short-term fixed income securities. See 'Investment
Objectives and Policies -- Quality and Diversification Requirements' in the SAI.
Such securities may be used to invest uncommitted cash balances, to maintain
liquidity to meet shareholder redemptions or to take a temporarily defensive
position against potential stock market declines. These securities include:
obligations of the United States Government and its agencies or
instrumentalities; money market mutual funds, commercial paper, bank
certificates of deposit and bankers' acceptances; and repurchase agreements
collateralized by these securities. Under market conditions where the Portfolio
or its Advisers have adopted a defensive investment posture, the Portfolio may
invest without limit in these securities. The Portfolio may also purchase
nonpublicly offered debt securities. See 'Additional Investment Information and
Risk Factors -- Illiquid Investments; Privately Placed and Other Unregistered
Securities.'
 
The Portfolio may also utilize equity futures contracts and options to a limited
extent. Specifically, the Portfolio may enter into futures contracts and options
provided that such positions are established for hedging purposes only. See
'Futures Contracts.'
 
The Portfolio may also sell securities short to a limited extent and for hedging
purposes only. See 'Short Sales.' The Fund may also invest in 'special
situations.' See 'Special Situations.'
 
The Portfolio intends to manage its securities actively in pursuit of its
investment objective. Although it generally seeks to invest for the long-term,
the Portfolio retains the right to sell securities irrespective of how long they
have been held. It is anticipated that the annual portfolio turnover of the
Portfolio will not exceed 100%. To the extent the Portfolio engages in
short-term trading, it may incur increased transaction costs.
 
ADDITIONAL INVESTMENT INFORMATION AND RISK FACTORS
 
CONVERTIBLE SECURITIES. The convertible securities in which the Portfolio may
invest include any debt securities or preferred stocks that may be converted
into common stock or that carry the right to purchase common stock. Convertible
securities entitle the holder to exchange the securities for a specified number
of shares of common stock, usually of the same company, at specified prices
within a certain period of time.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Portfolio may purchase
securities on a when-issued or delayed delivery basis. Delivery of and payment
for these securities may take as long as a month or more after the date of the
purchase commitment. The value of these securities is subject to market
fluctuation during this period and no interest or income accrues to the
Portfolio until settlement. At the time of settlement, a when-issued security
may be valued at less than its purchase price. Between the trade and settlement
dates, the Portfolio will maintain a segregated account with the Custodian
consisting of a portfolio of liquid securities with a value at least equal to
these commitments. When entering into a when-issued or delayed delivery
transaction, the Portfolio will rely on the other party to consummate the
transaction; if the other party fails to do so, the Portfolio may be
disadvantaged. It is the current policy of the Portfolio not to enter into
when-issued commitments exceeding in the aggregate 15% of the market value of
the Portfolio's total assets less liabilities (excluding the obligations created
by these commitments).
 
REPURCHASE AGREEMENTS. The Portfolio may engage in repurchase agreement
transactions with brokers, dealers or banks that meet the credit guidelines
approved by the Trust's Board of Trustees (the 'Trustees'). In a repurchase
agreement, the Portfolio buys a security from a seller that has agreed to
repurchase it at a mutually agreed upon date and price, reflecting the interest
rate effective for the term of the agreement. The term of these agreements is
usually from overnight to one week. A repurchase agreement may be viewed as a
fully collateralized loan of money by the Portfolio to the seller. The
 
                                      -6-
 



<PAGE>
<PAGE>
Portfolio always receives securities as collateral with a market value at least
equal to the purchase price plus accrued interest and this value is maintained
during the term of the agreement. If the seller defaults and the collateral's
value declines, the Portfolio might incur a loss. If bankruptcy proceedings are
commenced with respect to the seller, the Portfolio's realization upon the
disposition of collateral may be delayed or limited. Investments in repurchase
agreements maturing in more than seven days and certain other investments that
may be considered illiquid are limited. See 'Illiquid Investments; Privately
Placed and Other Unregistered Securities' below.
 
REVERSE REPURCHASE AGREEMENTS. The Portfolio is permitted to enter into reverse
repurchase agreements. In a reverse repurchase agreement, the Portfolio sells a
security and agrees to repurchase it at a mutually agreed upon date and price,
reflecting the interest rate effective for the term of the agreement. It may
also be viewed as the borrowing of money by the Portfolio and, therefore, is a
form of leverage. Leverage may cause any gains or losses of the Portfolio to be
magnified. For more information, including limitations on the use of reverse
repurchase agreements, see 'Investment Objectives and Policies' in the SAI and
'Investment Restrictions' below.
 
SECURITIES LENDING. Subject to applicable investment restrictions, the Portfolio
may lend its securities. The Portfolio may lend its securities if such loans are
secured continuously by cash or equivalent collateral or by a letter of credit
in favor of the Portfolio at least equal at all times to 100% of the market
value of the securities loaned, plus accrued interest. While such securities are
on loan, the borrower will pay the Portfolio any income accruing thereon. Loans
will be subject to termination by the Portfolio in the normal settlement time,
generally three business days after notice, or by the borrower on one day's
notice. Borrowed securities must be returned when the loan is terminated. Any
gain or loss in the market price of the borrowed securities that occurs during
the term of the loan inures to the Portfolio and its respective investors. The
Portfolio may pay reasonable finders' and custodial fees in connection with a
loan. In addition, the Portfolio will consider all the facts and circumstances,
including the creditworthiness of the borrowing financial institution, and the
Portfolio will not make any loans in excess of one year. The Portfolio will not
lend its securities to any officer, Trustee, Director, employee or affiliate or
placement agent of the Company, the Portfolio, or the Adviser, Sub-Adviser,
Administrator or Distributor, unless otherwise permitted by applicable law.
 
FOREIGN INVESTMENT INFORMATION. Investments in securities of foreign issuers and
in obligations of foreign branches of domestic banks involve somewhat different
investment risks from those affecting securities of domestic issuers. There may
be limited publicly available information with respect to foreign issuers, and
foreign issuers are not generally subject to uniform accounting, auditing and
financial standards and requirements comparable to those applicable to domestic
companies. Dividends and interest paid by foreign issuers may be subject to
withholding and other foreign taxes that may decrease the net return on such
investments.
 
Investors should realize that the value of the Portfolio's investments in
foreign securities may be adversely affected by changes in political or social
conditions, diplomatic relations, confiscatory taxation, expropriation,
nationalization, limitation on the removal of funds or assets, or imposition of
(or change in) exchange control or tax regulations in those foreign countries.
In addition, changes in government administrations or economic or monetary
policies in the United States or abroad could result in appreciation or
depreciation of portfolio securities and could favorably or unfavorably affect
the Portfolio's operations. Furthermore, the economies of individual foreign
nations may differ from the U.S. economy, favorably or unfavorably, in areas
such as growth of gross national product, rate of inflation, capital
reinvestment, resource self-sufficiency and balance of payments position; it may
also be more difficult to obtain and enforce a judgment against a foreign
issuer. Any foreign investments made by the Portfolio must be made in compliance
with U.S. and foreign currency restrictions and tax laws restricting the amounts
and types of foreign investments.
 
In addition, while the volume of transactions effected on foreign stock
exchanges has increased in recent years, in most cases it remains appreciably
below that of domestic security exchanges. Accordingly, the Portfolio's foreign
investments may be less liquid and their prices may be more volatile than
comparable investments in securities of U.S. companies. Moreover, the settlement
periods for foreign securities, which are often longer than those for securities
of U.S. issuers, may affect portfolio liquidity. In buying and
 
                                      -7-
 



<PAGE>
<PAGE>
selling securities on foreign exchanges, purchasers normally pay fixed
commissions that are generally higher than the negotiated commissions charged in
the United States. In addition, there is generally less government supervision
and regulation of securities exchanges, brokers and issuers located in countries
other than in the United States.
 
The Portfolio may invest in securities of foreign issuers directly or in the
form of American Depository Receipts ('ADRs'), European Depository Receipts
('EDRs'), Global Depositary Receipts ('GDRs') or other similar securities of
foreign issuers. These securities may not necessarily be denominated in the same
currency as the securities they represent. ADRs are receipts typically issued by
a U.S. bank or trust company evidencing ownership of the underlying foreign
securities. Certain institutions issuing ADRs may not be sponsored by the issuer
of the underlying foreign securities. A non-sponsored depository may not provide
the same shareholder information that a sponsored depository is required to
provide under its contractual arrangements with the foreign issuer. EDRs are
receipts issued by a European financial institution evidencing a similar
arrangement. GDRs are issued outside the United States, typically by non-U.S.
banks and trust companies. Generally, ADRs, in registered form, are designed for
use in the U.S. securities markets, and EDRs and GDRs, in bearer form, are
designed for use in European securities markets and domestic and European
securities markets, respectively.
 
Because investments in foreign securities involve foreign currencies, the value
of assets as measured in U.S. dollars may be affected, favorably or unfavorably,
by changes in currency exchange rates and in exchange control regulations,
including currency blockage. See 'Foreign Currency Exchange Transactions' below.
 
FOREIGN CURRENCY EXCHANGE TRANSACTIONS. Because the Portfolio may buy and sell
securities and receive interest and dividends in currencies other than the U.S.
dollar, the Portfolio may, from time-to-time, enter into foreign currency
exchange transactions. The Portfolio may enter into these transactions on a spot
(i.e., cash) basis at the spot rate prevailing in the foreign currency exchange
market, use forward currency contracts to purchase or sell foreign currencies,
use currency futures contracts or purchase or sell options thereon or purchase
or sell currency options.
 
A forward foreign currency exchange contract is an obligation of the Portfolio
to purchase or sell a specific currency at a future date, which may be any fixed
number of days from the date of the contract. Currency options give the buyer
the right, but not the obligation, to purchase or sell a fixed amount of a
specific currency at a fixed price at a future date. These contracts are entered
into in the interbank market directly between currency traders (usually large
commercial banks) and their customers. A forward foreign currency exchange
contract generally has no deposit requirement, and is traded at a net price
without commission. The Portfolio will not enter into these foreign currency
exchange transactions for speculative purposes. Foreign currency exchange
transactions do not eliminate fluctuations in the local currency prices of the
Portfolio's securities or in foreign exchange rates, or prevent loss if the
local currency prices of these securities should decline.
 
A currency futures contract is a contract involving an obligation to deliver or
acquire the specified amount of a currency at a specified price at a specified
future time. Futures contracts may be settled on a net cash payment basis rather
than by the sale and delivery of the underlying currency.
 
The Portfolio may enter into foreign currency exchange transactions in an
attempt to protect against changes in foreign currency exchange rates between
the trade and settlement dates of specific securities transactions or
anticipated securities transactions. The Portfolio may use these techniques to
hedge against a change in foreign currency exchange rates (with the U.S. dollar
or other foreign currencies) that would cause a decline in the value of existing
investments denominated or principally traded in a foreign currency.
 
Although these transactions are intended to minimize the risk of loss due to a
decline in the value of the hedged currency, these transactions also limit any
potential gain that might be realized should the value of the hedged currency
increase. Additionally, the premiums paid by the Portfolio for currency or
futures options increase the Portfolio's transaction costs. Similarly, the cost
of the Portfolio's spot currency exchange transactions is generally the
difference between the bid and offer spot rate of the currency being purchased
or sold. The precise matching of these transactions and the value of the
securities involved will
 
                                      -8-
 



<PAGE>
<PAGE>
not generally be possible because the future value of such securities in foreign
currencies will change as a consequence of market movements in the value of such
securities between the date such a transaction is entered into and the date it
matures. The projection of currency market movements is extremely difficult and
the successful execution of a hedging strategy is highly uncertain.
 
ILLIQUID INVESTMENTS; PRIVATELY PLACED AND OTHER UNREGISTERED SECURITIES. The
Portfolio may not acquire any illiquid securities if, as a result thereof, more
than 15% of the market value of the Portfolio's net assets would be in illiquid
investments or investments that are not readily marketable. In addition, the
Portfolio will not invest more than 10% of the market value of its total assets
in restricted securities (not including Rule 144A securities) that cannot be
offered for public sale in the United States without first being registered
under the Securities Act of 1933, as amended (the 'Securities Act'). Subject to
those non-fundamental policy limitations, the Portfolio may acquire investments
that are illiquid or have limited liquidity, such as private placements or
investments that are not registered under the Securities Act, and cannot be
offered for public sale in the United States without first being registered. An
illiquid investment is any investment that cannot be disposed of within seven
days in the normal course of business at approximately the amount at which it is
valued by the Portfolio. Repurchase agreements maturing in more than seven days
are considered illiquid investments and, as such, are subject to the limitations
set forth in this paragraph. The price the Portfolio pays for illiquid
securities or receives upon resale may be lower than the price paid or received
for similar securities with a more liquid market. Accordingly, the valuation of
these securities will reflect any limitations on their liquidity.
 
The Portfolio may also purchase Rule 144A securities sold to institutional
investors without registration under the Securities Act. These securities may be
determined to be liquid in accordance with guidelines established by the Adviser
and approved by the Trustees of the Trust. The Trustees of the Trust will
monitor the Adviser's implementation of these guidelines on a periodic basis.
 
SHORT SALES. In the event that the Adviser anticipates that the price of a
security will decline, the Adviser may sell the security short and borrow the
same security from a broker or other institution to complete the sale. The
Portfolio will incur a profit or a loss, depending upon whether the market price
of the security decreases or increases between the date of the short sale and
the date on which the Fund must replace the borrowed security. The Portfolio
will only enter into short sales for hedging purposes. All short sales will be
fully collateralized and the Portfolio will not sell securities short if
immediately after and as a result of the short sale the value of all securities
sold by the Portfolio exceeds 25% of its total assets. The Fund also limits
short sales of any one issuer's securities to 2% of the Fund's total assets and
to 2% of any one class of the issuer's securities.
 
SPECIAL SITUATIONS. From time to time, the Portfolio may invest in special
situations. A special situation arises when the Adviser believes that the
securities of a particular issuer will be recognized and appreciate in value due
to a specific development affecting that issuer. Developments that might create
a special situation include a new product or process, a technological
breakthrough, a management change, merger, recapitalization or other
extraordinary corporate event, or a change in market supply of and demand for
the security. Investments in special situations may carry an additional risk of
loss in the event that the anticipated development does not occur or does not
result in the anticipated market reaction.
 
MONEY MARKET INSTRUMENTS. The Portfolio is permitted to invest in money market
instruments although it intends to stay invested in equity securities to the
extent practical in light of its objective and long-term investment perspective.
The Portfolio may make money market investments pending other investments or
settlements, for liquidity or in adverse market conditions. Such money market
investments may include obligations of the U.S. Government and its agencies and
instrumentalities, money market mutual funds, commercial paper, bank obligations
and repurchase agreements. For more detailed information about these money
market investments, see 'Investment Objectives and Policies' in the SAI.
 
FUTURES AND OPTIONS TRANSACTIONS. The Portfolio is permitted to enter into the
futures and options transactions described below. These instruments are commonly
known as derivatives.
 
The Portfolio may purchase and sell exchange traded and over-the-counter ('OTC')
put and call options on equity securities or indices of equity securities, enter
into forward contracts, purchase and sell futures contracts on indices of equity
securities and purchase or sell put and call options on futures contracts on
 
                                      -9-
 



<PAGE>
<PAGE>
indices of equity securities. The Portfolio may use these techniques for hedging
or risk management purposes or, subject to certain limitations, for investment
purposes in lieu of investing directly in the corresponding securities or
instruments. Such use of derivatives may be considered speculative.
 
The Portfolio may use these techniques to manage its exposure to changing
interest rates and/or security prices. Some options and futures strategies,
including selling futures contracts and buying puts, tend to hedge the
Portfolio's investments against price fluctuations. Other strategies, including
buying futures contracts, writing puts and calls, and buying calls, may tend to
increase market exposure. For example, if the Portfolio wishes to obtain
exposure to a particular market or market sector but does not wish to purchase
the relevant securities, it could, as an alternative, purchase a futures
contract on an index of such securities or related securities. Such a purchase
would not constitute a hedging transaction and could be considered speculative.
However, the Portfolio will use futures contracts or options in this manner only
for the purpose of obtaining the same level of exposure to a particular market
or market sector that it could have obtained by purchasing the relevant
securities and will not use futures contracts or options to leverage its
exposure beyond this level. The use of options and futures may involve some
leverage; such leverage is reduced by the requirement of the SEC to 'cover' such
obligations. See 'Cover -- Segregated Accounts' below. Options and futures
contracts may be combined with each other or with forward contracts in order to
adjust the risk and return characteristics of the Portfolio's overall strategy
in a manner deemed appropriate to the Adviser and consistent with the
Portfolio's objective and policies. Because combined positions involve multiple
trades, they result in higher transaction costs and may be more difficult to
open and close out.
 
The Portfolio's use of these transactions is a highly specialized activity,
which involves investment strategies and risks different from those associated
with ordinary portfolio securities transactions, and there can be no guarantee
that their use will increase the Portfolio's return. While the Portfolio's use
of these instruments may reduce certain risks associated with owning its
portfolio securities, these techniques themselves entail certain other risks. If
the Adviser applies a strategy at an inappropriate time or judges market
conditions or trends incorrectly, such strategies may lower the Portfolio's
return. Certain strategies limit the Portfolio's opportunity to realize gains as
well as limiting its exposure to losses. The Portfolio could experience losses
if the prices of its options and futures positions were poorly correlated with
its other investments, or if it could not close out its positions because of an
illiquid secondary market. In addition, the Portfolio will incur costs,
including commissions and premiums, in connection with these transactions and
these transactions could significantly increase the Portfolio's turnover rate.
 
The Portfolio may purchase and sell put and call options on securities, indices
of securities and futures contracts, or purchase and sell futures contracts for
the purposes described herein.
 
In addition, in order to assure that the Portfolio will not be considered a
'commodity pool' for purposes of Commodity Futures Trading Commission ('CFTC')
rules, the Portfolio will enter into transactions in futures contracts or
options on futures contracts only if (1) such transactions constitute bona fide
hedging transactions as defined under CFTC rules, or (2) no more than 5% of the
Portfolio's net assets are committed as initial margin or premiums to positions
that do not constitute bona fide hedging transactions.
 
OPTIONS
 
PURCHASING PUT AND CALL OPTIONS. By purchasing a put option, the Portfolio
obtains the right (but not the obligation) to sell the instrument underlying the
option at a fixed strike price. In return for this right, the Portfolio pays the
current market price for the option (known as the option premium). Options have
various types of underlying instruments, including specific securities, indices
of securities, indices of securities prices and futures contracts. The Portfolio
may terminate its position in a put option it has purchased by allowing it to
expire or by exercising the option. The Portfolio may also close out a put
option position by entering into an offsetting transaction, if a liquid market
exists. If the option is allowed to expire, the Portfolio will lose the entire
premium it paid. If the Portfolio exercises a put option on a security, it will
sell the instrument underlying the option at the strike price. If the Portfolio
exercises an option on an index, settlement is in cash and does not involve the
actual sale of securities.
 
                                      -10-
 



<PAGE>
<PAGE>
American style options may be exercised on any day up to their expiration date.
European style options may be exercised only on their expiration date.
 
The buyer of a typical put option can expect to realize a gain if the price of
the underlying instrument falls substantially. However, if the price of the
instrument underlying the option does not fall enough to offset the cost of
purchasing the option, a put buyer can expect to suffer a loss (limited to the
amount of the premium paid, plus related transaction costs).
 
The features of call options are essentially the same as those of put options,
except that the purchaser of a call option obtains the right to purchase, rather
than sell, the instrument underlying the option at the option's strike price. A
call buyer typically attempts to participate in potential price increases of the
instrument underlying the option with risk limited to the cost of the option and
related transaction costs if security prices fall. At the same time, the buyer
can expect to suffer a loss if security prices do not rise sufficiently to
offset the cost of the option.
 
SELLING (WRITING) PUT AND CALL OPTIONS. When the Portfolio writes a put option,
it takes the opposite side of the transaction from the option's purchaser. In
return for receipt of the premium, the Portfolio assumes the obligation to pay
the strike price for the instrument underlying the option if the other party to
the option chooses to exercise it. The Portfolio may seek to terminate its
position in a put option it writes before exercise by purchasing an offsetting
option in the market at its current price. If the market is not liquid for a put
option the Portfolio has written, however, the Portfolio must continue to be
prepared to pay the strike price while the option is outstanding, regardless of
price changes, and must continue to post margin as discussed below.
 
If the price of the underlying instrument rises, a put writer would generally
expect to profit, although its gain would be limited to the amount of the
premium it received. If security prices remain the same over time, it is likely
that the writer will also profit, because it should be able to close out the
option at a lower price. If security prices fall, however, the put writer would
expect to suffer a loss. This loss should be less than the loss from purchasing
and holding the underlying instrument directly, however, because the premium
received for writing the option should offset a portion of the decline.
 
Writing a call option obligates the Portfolio to sell or deliver the option's
underlying instrument in return for the strike price upon exercise of the
option. The characteristics of writing call options are similar to those of
writing put options, except that writing calls generally is a profitable
strategy if prices remain the same or fall. Through receipt of the option
premium a call writer offsets part of the effect of a price decrease. At the
same time, because a call writer must be prepared to deliver the underlying
instrument in return for the strike price, even if its current value is greater,
a call writer gives up some ability to participate in security price increases.
 
The writer of a U.S. exchange traded put or call option on a security, an index
of securities or a futures contract is required to deposit cash or securities or
a letter of credit as margin and to make mark-to-market payments of variation
margin if and as the position becomes unprofitable.
 
OPTIONS ON INDICES. The Portfolio is permitted to enter into options
transactions and may purchase and sell put and call options on any securities
index based on securities in which the Portfolio may invest. Options on
securities indices are similar to options on securities, except that the
exercise of securities index options is settled by cash payment and does not
involve the actual purchase or sale of securities. In addition, these options
are designed to reflect price fluctuations in a group of securities or segment
of the securities market rather than price fluctuations in a single security.
The Portfolio, in purchasing or selling index options, is subject to the risk
that the value of its portfolio securities may not change as much as an index
because the Portfolio's investments generally will not match the composition of
an index.
 
For a number of reasons, a liquid market may not exist and thus the Portfolio
may not be able to close out an option position that it has previously entered
into. When the Portfolio purchases an OTC option, it will be relying on its
counterparty to perform its obligations, and the Portfolio may incur additional
losses if the counterparty is unable to perform.

FUTURES CONTRACTS
 
When the Portfolio purchases a futures contract, it agrees to purchase a
specified quantity of an underlying instrument at a specified future date and
price or to make or receive a cash payment based on the value of a securities
index. When the Portfolio sells a futures contract, it agrees to sell a
specified quantity of the underlying instrument at a specified future date and
price or to receive or make a cash payment based on the value of a securities
index. The price at which the purchase and sale will take place is fixed when
the Portfolio enters into the contract. Futures can be held until their delivery
dates or the positions can be (and normally are) closed out before then. There
is no assurance, however, that a liquid market will exist when a Portfolio
wishes to close out a particular position.
 
When the Portfolio purchases or sells a futures contract, the value of the
futures contract tends to increase and decrease in tandem with the value of its
underlying instrument. Purchasing futures contracts may tend to increase the
Portfolio's exposure to positive and negative price fluctuations in the
underlying instrument, much as if it had purchased the underlying instrument
directly, as discussed above. When the Portfolio sells a futures contract, by
contrast, the value of its futures position will tend to move in a direction
contrary to the value of the underlying instrument. Selling futures contracts on
securities similar to those held by the Portfolio, therefore, will tend to
offset both positive and negative market price changes, much as if the
underlying instrument had been sold. Because there are a limited number of types
of exchange-traded options and futures contracts, it is likely that these
standardized instruments will not exactly match the Portfolio's current or
anticipated investments. The Portfolio may invest in futures contracts and
options thereon based on currencies or on securities with different issuers,
maturities, or other characteristics from the securities in which it typically
invests, which involves a risk that the options or futures position will not
track the performance of the Portfolio's other investments. The Portfolio may
also enter into transactions in futures contracts and options for non-hedging
purposes, as discussed above.
 
The purchaser or seller of a futures contract is not required to deliver or pay
for the underlying instrument unless the contract is held until the delivery
date. However, when the Portfolio buys or sells a futures contract it will be
required to deposit 'initial margin' either with the Custodian in a segregated
account in the name of its futures broker, known as a futures commission
merchant ('FCM'), or with the FCM. Initial margin deposits are typically equal
to a small percentage of the contract's value. If the value of either party's
position declines, that party will be required to make additional 'variation
margin' payments equal to the change in value on a daily basis. The party that
has a gain may be entitled to receive all or a portion of this amount. The
Portfolio may be obligated to make payments of variation margin at a time when
it is disadvantageous to do so. Furthermore, it may not always be possible for
the Portfolio to close out its futures positions. Until it closes out a futures
position, the Portfolio will be obligated to continue to pay variation margin.
Initial and variation margin payments do not constitute purchasing on margin for
purposes of the Portfolio's investment restrictions. In the event of the
bankruptcy of an FCM that holds margin on behalf of the Portfolio, the Portfolio
may be entitled to return of margin owed to it only in proportion to the amount
received by the FCM's other customers, potentially resulting in losses to the
Portfolio.
 
COVER -- SEGREGATED ACCOUNTS. The Portfolio will segregate liquid securities in
connection with its use of options and futures contracts to the extent required
by the SEC. Securities held in a segregated account cannot be sold while the
futures contract or option is outstanding, unless they are replaced with other
suitable assets. As a result, there is a possibility that the segregation of a
large percentage of the Portfolio's assets could impede portfolio management or
the Portfolio's ability to meet redemption requests or other current
obligations.
 
For further information about the Portfolio's use of futures and options and a
more detailed discussion of associated risks, see 'Investment Objectives and
Policies' in the SAI.
 
INVESTMENT RESTRICTIONS
 
The investment objective of the Fund and the Portfolio, together with the
investment restrictions described below and in the SAI, except as noted, are
deemed fundamental policies, i.e., they may be
 
                                      -12-
 



<PAGE>
<PAGE>
changed only by the 'vote of a majority of the outstanding voting securities'
(as defined in the Investment Company Act of 1940 (the '1940 Act')), of the Fund
or the Portfolio, respectively. The Fund has the same investment restrictions as
the Portfolio, except that the Fund may invest all of its investable assets in
another open-end investment company with the same investment objective and
restrictions (such as the Portfolio). References below to the Portfolio's
investment restrictions also include the Fund's investment restrictions.
 
As a diversified investment company, 75% of the total assets of the Portfolio
are subject to the following fundamental limitations: (a) the Portfolio may not
invest more than 5% of its total assets in the securities of any one issuer,
except U.S. Government securities; and (b) the Portfolio may not own more than
10% of the outstanding voting securities of any one issuer.
 
The Portfolio may not: (i) purchase the securities or other obligations of
issuers conducting their principal business activity in the same industry if its
investments in such industry would exceed 25% of the value of the Portfolio's
total assets, except this limitation shall not apply to investments in U.S.
Government securities; (ii) enter into reverse repurchase agreements or other
permitted borrowings that constitute senior securities under the 1940 Act,
exceeding in the aggregate one-third of the value of the Portfolio's total
assets; or (iii) borrow money, except from banks for extraordinary or emergency
purposes, or mortgage, pledge or hypothecate any assets except in connection
with any such borrowings or permitted reverse repurchase agreements in amounts
up to one-third of the value of the Portfolio's total assets at the time of such
borrowing, or purchase securities while borrowings and other senior securities
exceed 5% of its total assets. For a more detailed discussion of the above
investment restrictions, as well as a description of certain other investment
restrictions, see 'Investment Restrictions' and 'Additional Information' in the
SAI.
 
MANAGEMENT
 
DIRECTORS AND TRUSTEES. Pursuant to the Trust's Declaration of Trust, the
Trustees of the Trust establish the Portfolio's general policies, are
responsible for the overall management of the Trust, and review the actions of
the Adviser, Sub-Adviser, Administrator and other service providers. Similarly,
the Directors of the Company set the Company's general policies, are responsible
for the overall management of the Company, and review the performance of its
service providers. Additional information about the Company's Board of Directors
and officers appears in the SAI under the heading 'Directors and Trustees'. The
Trustees of the Trust are also the Directors of the Company, which raises
certain conflicts of interest. The Company and the Trust have each adopted
written procedures reasonably designed to deal with these conflicts, should they
arise. The officers of the Company are also employees of Investors Bank or its
affiliates.
 
ADVISER AND FUNDS SERVICES AGENT. The Company has not retained the services of
an investment adviser with respect to the Fund because the Fund seeks to achieve
its investment objective by investing all of its investable assets in the
Portfolio. The Portfolio has retained the services of the New York Branch (the
'Branch' or the 'Adviser') of Union Bank of Switzerland (the 'Bank') as
investment adviser and UBS Asset Management (New York) Inc. ('UBSAM') as
investment sub-adviser (the 'Sub-Adviser' and, together with the Branch, the
'Advisers'). The Branch, which operates out of offices located at 1345 Avenue of
the Americas, New York, New York, is licensed by the Superintendent of Banks of
the State of New York under the banking laws of the State of New York and is
subject to state and federal banking laws and regulations applicable to a
foreign bank that operates a state licensed branch in the United States. UBSAM,
which also operates out of offices located at 1345 Avenue of the Americas, New
York, New York, is a registered investment adviser in the U.S.
 
   
The Bank has branches, agencies, representative offices and subsidiaries in
Switzerland and in more than 40 cities outside Switzerland, including, in the
United States, New York City, Houston, Los Angeles and San Francisco. In
addition to the receipt of deposits and the making of loans and advances, the
Bank, through its offices and subsidiaries engages in a wide range of banking
and financial activities typical of the world's major international banks,
including fiduciary, investment advisory and custodial services and foreign
exchange in the United States, Swiss, Asian and Euro-capital markets. The Bank
is one of the world's leading asset managers and has been active in New York
City since 1946. At June 30, 1997, the
    
 
                                      -13-

Bank (including its consolidated subsidiaries) had total assets of $352.1
billion (unaudited) and equity capital and reserves of $16.2 billion
(unaudited).
    
 
The Advisers provide investment advice and portfolio management to the
Portfolio. Subject to the supervision of the Trustees and the Adviser, the
Sub-Adviser makes the Portfolio's day-to-day investment decisions, arranges for
the execution of portfolio transactions and generally manages the Portfolio's
investments and operations. See 'Investment Adviser and Funds Services Agent' in
the SAI.
 
In addition to the above-listed investment advisory services, the Branch also
provides the Fund and the Portfolio with certain related administrative
services. Subject to the supervision of the Directors and Trustees,
respectively, the Branch is responsible for: establishing performance standards
for the third-party service providers of the Fund and Portfolio and overseeing
and evaluating the performance of such entities; providing and presenting
quarterly management reports to the Directors and the Trustees; supervising the
preparation of reports for Fund and Portfolio shareholders; and establishing
voluntary expense limitations for the Fund and providing any resultant expense
reimbursement to the Fund.
 
The Branch provides its administrative services to the Fund pursuant to a Funds
Services Agreement between the Branch and the Company. The Branch does not
receive a fee from the Company or the Fund pursuant to the terms of the Funds
Services Agreement.
 
Under the Trust's Investment Advisory Agreement, the Portfolio pays the Adviser
a fee, calculated daily and payable monthly, equal, on an annual basis, to 0.60%
of the Portfolio's average daily net assets. The Branch has voluntarily agreed
to waive its fees and reimburse the Fund and the Portfolio for any of their
respective direct and indirect expenses to the extent that the Fund's total
operating expenses (including its share of the Portfolio's expenses) exceed, on
an annual basis, 1.00% of the Fund's average daily net assets. The Branch may
modify or discontinue this fee waiver and expense limitation at any time in the
future with 30 days' prior notice to the Fund. See 'Expenses'.
 
   
SUB-ADVISER. The Sub-Adviser uses a sophisticated, disciplined, collaborative
process for managing the Portfolio. Wayne D. Thornbrough, CFA is primarily
responsible for the day-to-day management and implementation of the
Sub-Adviser's process for the Portfolio. Mr. Thornbrough has thirty years
investment experience and has been the Chief Investment Officer and a Managing
Director of the Sub-Adviser since 1995. Previously, Mr. Thornbrough has been
affiliated with a number of investment firms, including State Street Research
and Dillon, Read & Co. Mr. Thornbrough received an MBA from Harvard University
Business School and a BA from Harvard University. The Sub-Adviser has advised
mutual funds for only a short time.
    
 
   
Pursuant to the Sub-Advisory Agreement between the Adviser and the Sub-Adviser,
the Adviser has agreed to pay the Sub-Adviser a fee, calculated daily and
payable monthly equal, on an annual basis, to 0.30% of the first $25 million of
the Portfolio's average daily net assets plus 0.25% of the next $25 million of
such assets plus 0.20% on such assets in excess of $50 million. The Adviser is
solely responsible for paying the Sub-Adviser this fee.
    
 
INVESTMENTS IN THE FUND ARE NOT DEPOSITS WITH OR OBLIGATIONS OF, OR GUARANTEED
OR ENDORSED BY, THE BRANCH OR ANY OTHER BANK.
 
ADMINISTRATORS. The Fund and the Portfolio employ Investors Bank & Trust Company
('Investors Bank') and Investors Fund Services (Ireland) Limited ('IBT
Ireland'), a subsidiary of Investors Bank, respectively, as administrators under
Adminstration Agreements (the 'Administration Agreements') to provide certain
administrative services. The services provided by Investors Bank and IBT Ireland
under the Administration agreements include certain accounting, clerical and
bookkeeping services, Blue Sky (for the fund only), corporate secretarial
services and assistance in the preparation and filing of tax returns and reports
to shareholders and the Securities and Exchange Commission ('SEC'). Investors
Bank is a wholly-owned subsidiary of Investors Financial Services Corp., a
publicly-held corporation and holding company registered under the Bank Holding
Company Act of 1956.
 
For its services under the Administration Agreement, the Fund has agreed to pay
Investors Bank a fee, calculated daily and payable monthly, equal, on an annual
basis, to 0.065% of the Fund's first $100
 
                                      -14-

<PAGE>

million of average daily net assets and 0.025% of the next $100 million of
average daily net assets. Investors Bank does not receive a fee from the Fund on
average daily net assets in excess of $200 million.
 
For its services under the Administration Agreement, the Portfolio has agreed to
pay IBT Ireland a fee, calculated daily and payable monthly, equal, on an annual
basis, to 0.07 of the Portfolio's first $100 million of average daily net assets
and 0.05% of average daily net assets in excess of $100 million. IBT Ireland's
principal offices are located at Deloitte & Touche House, 29 Earlsfort Terrace,
Dublin 2, Ireland. Investors Bank's principal offices are located at 200
Clarendon Street, Boston, Massachusetts 02116.
 
DISTRIBUTOR. Pursuant to a Distribution Agreement, First Fund Distributors, Inc.
(the 'Distributor') serves as the distributor of Fund shares. The Distributor is
a broker-dealer registered with the SEC and is a member of the National
Association of Securities Dealers, Inc. ('NASD'). The Distributor is authorized
by the NASD to act as a mutual fund underwriter and distributor. The principal
offices of the Distributor are located at 4455 E. Camelback Road, Phoenix,
Arizona 85018. The Distributor does not receive a fee pursuant to the terms of
the Distribution Agreement, but receives compensation from Investors Bank.
 
CUSTODIAN. Investors Bank also serves as the Custodian for the Portfolio and the
Fund and transfer and dividend disbursing agent for the Fund. See 'Custodian' in
the SAI. The Custodian also maintains offices at 1 First Canadian Place, Suite
2800, Toronto, Ontario M5X1C8.
 
SHAREHOLDER SERVICES
 
The Company has entered into a shareholder servicing agreement with the Branch,
and may enter into additional shareholder servicing agreements with one or more
financial institutions (together with the Branch, 'Eligible Institutions') such
as a federal or state-chartered bank, trust company, savings and loan
association or savings bank, or broker-dealer. Pursuant to each shareholder
servicing agreement, an Eligible Institution, as agent for its customers who are
purchasing shares of the Fund, will perform the following services for these
investors, among other things: coordinating shareholder accounts and records,
assisting investors seeking to purchase or redeem Fund shares, providing
performance information relating to the Fund, and responding to shareholder
inquiries. The Company has agreed to pay each Eligible Institution a fee for
these services equal, on an annual basis, to 0.25% of the average daily net
assets of the Fund represented by shares of the Fund owned during the period for
which payment is being made by customers of the Eligible Institution. Under the
terms of the shareholder servicing agreements, Eligible Institutions may
delegate one or more of their responsibilities to other entities at their
expense.
 
EXPENSES
 
In addition to the fees of the Branch, Investors Bank and IBT Ireland, the Fund
will be responsible for other expenses, including brokerage costs and litigation
and extraordinary expenses. The Branch has voluntarily agreed to limit the total
operating expenses of the Fund, excluding extraordinary expenses, to an annual
rate of 1.00% of the Fund's average daily net assets. The Branch may modify or
discontinue this voluntary expense limitation at any time in the future with 30
days' prior notice to the Fund.
 
The Fund and the Portfolio may allocate brokerage transactions to their
affiliates and the Adviser's affiliates only if the commissions received by such
affiliates are fair and reasonable when compared to the commissions paid to
unaffiliated brokers in connection with comparable transactions. See 'Portfolio
Transactions' in the SAI.
 
PURCHASE OF SHARES
 
GENERAL INFORMATION ON PURCHASES. Investors may purchase Fund shares only
through the Distributor. All purchase orders must be accepted by the
Distributor. The Fund also reserves the right to determine the purchase orders
that it will accept and reserves the right to cease offering its shares for a
period of time. The shares of the Fund may be purchased only in those states
where they may be lawfully sold.
 
The minimum initial investment in the Fund is $25,000, except that the minimum
initial investment is $10,000 for shareholders of another series of the Company.
The minimum subsequent investment in the Fund for all investors is $5,000. The
minimum initial investment for employees of the Bank or its
 
                                      -15-
 



<PAGE>
<PAGE>
affiliates is $5,000 and the minimum subsequent investment is $1,000. These
minimum investment requirements may be waived at the Fund's sole discretion.
 
No share certificates will be issued.
 
PURCHASE PRICE AND SETTLEMENT. The shares of the Fund are sold on a continuous
basis without a sales charge at the net asset value per share next determined
after receipt and acceptance of a purchase order by the Distributor. The Fund
calculates its net asset value at the close of business on any day on which the
New York Stock Exchange (the 'NYSE') is open for regular trading (a 'Fund
Business Day'). Purchase orders received and accepted by the Distributor prior
to 4:00 p.m. New York time on any Fund Business Day will be effective and is
executed at the net asset value determined that day. The purchaser becomes a
holder of record that day, provided the Fund receives payment for those shares
on the following business day ('settlement date') and as a recordholder is
entitled to earn dividends. Purchase orders received after 4:00 p.m. will
receive the net asset value determined on the next Fund Business Day, and the
investor becomes a holder of record on the business day following the Fund's
receipt of payment. Investors will receive the number of full and fractional
shares of the Fund equal to the dollar amount of their subscription divided by
the net asset value per share of the Fund next determined on the day that the
investor's purchase is accepted. See also 'Purchase of Shares' in the Statement
of Additional Information.
 
Customers of Eligible Institutions should request a representative of their
Eligible Institution to assist them in placing a purchase order with the
Distributor. Shareholders who do not currently maintain a relationship with an
Eligible Institution may purchase shares of the Fund directly from the
Distributor by wire transfer or mail.
 
By wire transfer: Purchases may be made by federal funds wire. To place a
purchase order with the Fund, the shareholder must telephone the Transfer Agent
at (888) UBS-FUND (888-827-3863). A completed account application must promptly
follow any wire order for an initial purchase. Completed account applications
should be mailed or sent via facsimile. Investors should contact the Transfer
Agent for further instructions regarding account applications. Account
applications are not required for subsequent purchases; however, the investor's
account number must be clearly indicated on the wire to ensure proper credit.
 
All investments must be paid for by U.S. Federal Funds wire. An investor should
instruct its bank to wire federal funds as indicated below on settlement date:

Investors Bank & Trust Company; P.O. Box 9130; MFD 23; Boston, Massachusetts
02117-9130.
 
Checks are subject to collection at full value. For shares purchased by check,
dividend payments and redemption proceeds, if any, will be delayed until such

Fund will not accept third-party checks.
 
The Transfer Agent will maintain the accounts for all shareholders of record.
For account balance information and shareholder services, shareholders should

REDEMPTION OF SHARES
 
GENERAL INFORMATION ON REDEMPTIONS. A shareholder may redeem all or any number
of the shares registered in its name at any time at the net asset value next
determined after a redemption request in
 
                                      -16-
 



<PAGE>
<PAGE>
proper form is received by the Distributor. To be in proper form, the Fund must
have received the shareholder's taxpayer identification number and address.
Redemption requests must include the name of the Fund, the dollar amount or
number of shares to be redeemed and the shareholder's account number. The
request must be signed by a person who is authorized to transact on behalf of
the shareholder. In all cases, all signatures on a redemption request must be
signature guaranteed by an eligible guarantor institution which includes a
domestic bank, a domestic savings and loan institution, a domestic credit union,
a member bank of the Federal Reserve System or a member firm of a national
securities exchange, pursuant to the Fund's standards and procedures. If the
guarantor institution belongs to one of the Medallion Signature programs, it
must use the specific 'Medallion Guaranteed' stamp. Guarantees by notaries
public are not acceptable. Further documentation, such as copies of corporate
resolutions and instruments of authority may be requested from corporations,
administrators, executors, personal representatives, trustees or custodians to
evidence the authority of the person or entity making the redemption request.
 
Customers of Eligible Institutions must request a representative of their
Eligible Institution to assist them in placing a redemption order with the Fund.
 
REDEMPTION PRICE AND SETTLEMENT. Redemption orders received by the Distributor
in good form prior to 4:00 p.m. New York time on any Fund Business Day will be
effected and executed at the net asset value determined on that day. Redemption
orders received after 4:00 p.m. New York time will be effected and executed at
the net asset value determined on the next Fund Business Day. Proceeds from the
redemption will be generally deposited the next business day in immediately
available funds to the account designated by the redeeming shareholder, or sent
by check to the address of record if requested by the shareholder.
 
Shareholders will continue to earn dividends through the day of redemption.
 
Shareholders who maintain an account directly with the Distributor may redeem
Fund shares by mail or telephone.
 
By mail: Redemption requests may be mailed to the Transfer Agent, identifying
the Fund, the dollar amount or number of shares to be redeemed and the
shareholder's account number. The request must be signed in exactly the same
manner as the account is registered (e.g., if there is more than one owner of
the shares, all must sign). In all cases, a signature guarantee is required. See
'General Information on Redemptions' above.
 
By telephone: The shareholder may place a redemption request by calling the
Transfer Agent at 888-UBS-FUND (888-827-3863). Shareholders utilizing the
telephone redemption option must have previously designated this option on the
initial account application, or by subsequent written authorization to the Fund.
Such shareholders risk possible loss of principal and income in the event of a
telephone redemption not authorized by them. The Fund and the Transfer Agent
will employ reasonable procedures to verify that telephone redemption
instructions are genuine and will require that shareholders electing such an
option provide a form of personal identification. The failure by the Fund or the
Transfer Agent to employ such procedures may cause the Fund or the Transfer
Agent to be liable for any losses incurred by investors due to telephone
redemptions based upon unauthorized or fraudulent instructions. The telephone
redemption option may be modified or discontinued at any time upon 60 days'
notice to shareholders.
 
MANDATORY REDEMPTION. If the value of a shareholder's holdings in the Fund falls
below $10,000 because of a redemption of shares, the shareholder's remaining
shares may be redeemed 60 days after written notice unless the account is
increased to $10,000 or more. For example, a shareholder whose initial and only
investment is $10,000 may be subject to mandatory redemption resulting from any
redemption that causes his or her investment to fall below $10,000.
 
FURTHER REDEMPTION INFORMATION. Investors should be aware that redemptions may
not be processed unless the redemption request is submitted in proper form. To
be in proper form, the Fund must have received the shareholder's taxpayer
identification number and address. As discussed under 'Taxes' below, the Fund
may be required to impose 'back-up' withholding of federal income tax on
dividends, distributions and redemptions when non-corporate investors have not
provided a certified taxpayer identification number. In addition, if an investor
sends a check to the Distributor for the purchase of
 
                                      -17-
 



<PAGE>
<PAGE>
Fund shares and shares are purchased with funds made available by the
Distributor before the check has cleared, the transmittal of redemption proceeds
from the sale of those shares will not occur until the check used to purchase
such shares has cleared, which may take up to 15 days. Redemption delays may be
avoided by purchasing shares by federal funds wire.
 
The right of redemption may be suspended or the date of payment postponed for
such periods as the 1940 Act or the SEC may permit. See 'Redemption of Shares'
in the SAI.
 
EXCHANGE OF SHARES
 
An investor may exchange Fund shares for shares of any other series of the
Company, without charge. An exchange may be made so long as after the exchange
the investor has shares, in each series in which it remains an investor, with a
value equal to or greater than each such series' minimum investment amount. See
'Purchase of Shares' in the prospectuses of the other Company series for the
minimum investment amounts for each of those funds. Shares are exchanged on the
basis of relative net asset value per share. Exchanges are in effect redemptions
from one fund and purchases of another fund and the usual purchase and
redemption procedures and requirements are applicable to exchanges. See
appropriate section relating to the purchase and redemption of shares in this
and other prospectuses. See also 'Additional Information' below for an
explanation of the telephone exchange policy.
 
Shareholders subject to federal income tax who exchange shares in one fund for
shares in another fund may recognize capital gain or loss for federal income tax
purposes. The Fund reserves the right to discontinue, alter or limit its
exchange privilege at any time. For investors in certain states, state
securities laws may restrict the availability of the exchange privilege.
 
RETIREMENT PLANS
 
The Fund has available a form of Individual Retirement Account ('IRA') for
investment in Fund shares. Subject to certain restrictions imposed by applicable
tax laws, self-employed individuals may purchase shares of the Fund through
tax-deductible contributions to existing retirement plans known as Self-Employed
Retirement Plans ('SERPs'). Fund shares may also be a suitable investment for
'401(k) Plans' which subject to certain restrictions allow their participants to
invest in qualified pension plans on a tax-deferred basis. The Fund does not
currently act as sponsor to such plans.
 
The minimum initial investment for all such retirement plans is $2,000. The
minimum for all subsequent investments is $500.
 
Under the Internal Revenue Code of 1986, as amended (the 'Tax Code'),
individuals may make IRA contributions of up to $2,000 annually, which may be,
depending on the contributor's participation in an employer-sponsored plan and
income level, wholly or partly tax-deductible. However, dividends and
distributions held in the account are not taxed until withdrawn in accordance
with the provisions of the Tax Code. An individual with a non-working spouse may
establish a separate IRA for the spouse under the same conditions and contribute
a combined maximum of $4,000 annually to one or both IRAs provided that no more
than $2,000 may be contributed to the IRA of either spouse.
 
Investors should be aware that they may be subject to penalties or additional
taxes on contributions to or withdrawals from IRAs or other retirement plans
under certain circumstances. Prior to a withdrawal, shareholders may be required
to certify as to their age and awareness of such restrictions in writing.
Clients of Eligible Institutions desiring information concerning investments
through IRAs or other retirement plans should contact their Eligible
Institution. Clients who do not maintain a relationship with an Eligible
Institution may obtain such information by calling the Transfer Agent at (888)
UBS-FUND.
 
DIVIDENDS AND DISTRIBUTIONS
 
Dividends consisting of substantially all of the Fund's net investment income,
if any, are declared and paid annually. The Fund may also declare an additional
dividend of net investment income in a given year to the extent necessary to
avoid the imposition of federal excise taxes on the Fund.
 
                                      -18-

<PAGE>
Substantially all of the Fund's realized net capital gains, if any, will be
declared and paid on an annual basis, except that an additional capital gains
distribution may be made in a given year to the extent necessary to avoid the
imposition of federal excise taxes on the Fund. Declared dividends and
distributions are payable on the payment date to shareholders of record on the
record date.
 
Dividends and capital gains distributions paid by the Fund are automatically
reinvested in additional Fund shares unless the shareholder has elected, in
writing, to have them paid in cash. Dividends and distributions to be paid in
cash are credited to the account designated by the shareholder or sent by check
to the shareholder's address of record, in accordance with the shareholder's
instructions. The Fund reserves the right to discontinue, alter or limit the
automatic reinvestment privilege at any time.
 
NET ASSET VALUE
 
The Fund's net asset value per share equals the value of the Fund's total assets
(i.e., the value of its investment in the Portfolio plus its other assets) less
the amount of its liabilities, divided by the number of its outstanding shares,
rounded to the nearest cent. Expenses, including the fees payable to the service
providers of the Fund and the Portfolio, are accrued daily. Securities for which
market quotations are readily available are valued at market value. All other
securities will be valued at 'fair value'. See 'Net Asset Value' in the SAI for
information on the valuation of the Portfolio's assets and liabilities.
 
The Fund computes its net asset value once daily at the close of business on
Monday through Friday, except that the net asset value is not computed for the
Fund on a day in which no orders to purchase or redeem Fund shares have been
received or on any day on which the New York Stock Exchange is closed, including
the following holidays: New Year's Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. On days
when U.S. trading markets close early in observance of these holidays, the Fund
expects to close for purchases and redemptions at the same time.
 
ORGANIZATION
 
UBS PRIVATE INVESTOR FUNDS, INC.
 
UBS Private Investor Funds, Inc., a Maryland corporation incorporated on
November 16, 1995, is an open-end management investment company registered under
the 1940 Act and organized as a series fund. The Company is currently authorized
to issue shares in eight series: The UBS Bond Fund Series; The UBS Tax Exempt
Bond Fund Series; The UBS High Yield Bond Fund Series; The UBS International
Equity Fund Series; The UBS Institutional International Equity Fund Series; The
UBS U.S. Equity Fund Series; The UBS Small Cap Growth Fund Series; and The UBS
Large Cap Growth Fund Series. Each outstanding share of the Company will have a
pro rata interest in the assets of its series, but it will have no interest in
the assets of any other Company series. Only shares of The UBS Large Cap Growth
Fund Series are offered through this Prospectus.
 
Shareholder inquiries by clients of Eligible Institutions may be directed to
their Eligible Institution and other shareholders may address their inquiries to
the Transfer Agent.
 
Shareholders of the Fund are entitled to one vote for each share and to the
appropriate fractional vote for each fractional share. There is no cumulative
voting. Shares have no preemptive or conversion rights. Shares are fully paid
and nonassessable when issued by the Company. The Company does not intend to
hold meetings of shareholders annually. The Directors may call meetings of
shareholders for action by shareholder vote as may be required by its Articles
of Incorporation or the 1940 Act. For further organizational information,
including certain shareholder rights, see 'Organization' in the SAI.
 
UBS INVESTOR PORTFOLIOS TRUST
 
UBS Investor Portfolios Trust, a master trust fund formed under New York law,
was organized on February 9, 1996. The Declaration of Trust permits the Trustees
to issue interests divided into one or more subtrusts or series. To date, seven
series have been authorized, of which UBS Large Cap Growth Portfolio is one.
 
                                      -19-
 



<PAGE>
<PAGE>
The Declaration of Trust provides that no Trustee, shareholder, officer,
employee, or agent of the Trust shall be held to any personal liability, nor
shall resort be had to such person's private property for the satisfaction of
any obligation or claim or otherwise in connection with the affairs of the
Portfolio, but that only the Trust property shall be liable.
 
The Declaration of Trust provides that the Fund and other entities investing in
the Portfolio (e.g., other investment companies, insurance company separate
accounts and common and commingled trust funds) will each be liable for all the
obligations of the Portfolio. However, the risk of the Fund's incurring
financial loss on account of such liability is limited to circumstances in which
both inadequate insurance existed and the Portfolio itself was unable to meet
its obligations. Accordingly, the Trustees believe that neither the Fund nor its
shareholders will be adversely affected by reason of the Fund's investment in
the Portfolio.
 
TAXES
 
The Fund intends to qualify as a regulated investment company (a 'RIC') under
Subchapter M of the Tax Code. As a RIC, a Fund (as opposed to its shareholders)
will not be subject to federal income taxes on the net investment income and
capital gains that it distributes to its shareholders, provided that at least
90% of its net investment income and realized net short-term capital gains in
excess of net long-term capital losses for the taxable year is distributed. The
Portfolio intends to qualify as a partnership for federal income tax purposes.
As such, the Portfolio generally should not be subject to tax. The status of the
Fund as a regulated investment company is dependent on, among other things, the
Portfolio's continued qualification as a partnership for federal income tax
purposes.
 
Dividends from net investment income and distributions from realized net
short-term capital gains in excess of net long-term capital losses are taxable
as ordinary income to Fund shareholders whether such distributions are received
in the form of cash or reinvested in additional shares. To the extent that
dividends distributed to shareholders are designated as derived from the Fund's
dividend income that would be eligible for the dividends received deduction if
the Fund were not a regulated investment company, such dividends are eligible,
subject to certain restrictions, for the 70% dividends received deduction for
corporations. Distributions of net long-term capital gains in excess of net
short-term capital losses are taxable to Fund shareholders as long-term capital
gains regardless of how long a shareholder has held shares in the Fund and
regardless of whether received in the form of cash or reinvested in additional
shares. Long-term capital gains distributions to corporate shareholders are not
eligible for the dividends-received deduction. Annual statements as to the
current federal tax status of distributions will be mailed to shareholders after
the end of the taxable year for the Fund.
 
Any gain or loss realized on the redemption or exchange of Fund shares by a
shareholder who is not a dealer in securities generally will be treated as
long-term capital gain or loss if the shares have been held for more than one
year, and otherwise as short-term capital gain or loss. However, any loss
realized by a shareholder upon the redemption or exchange of shares in the Fund
held for six months or less will be treated as a long-term capital loss to the
extent of any long-term capital gain distributions received by the shareholder
with respect to such shares. In addition, no loss will be allowed on the sale or
other disposition of shares of the Fund if, and to the extent that, within a
period beginning 30 days before the date of such sale or disposition and ending
30 days after such date, the holder acquires (such as through dividend
reinvestment) securities that are substantially identical to the shares of the
Fund.
 
The Fund will generally be subject to an excise tax of 4% on the amount of any
income or capital gains, above certain permitted levels, distributed to
shareholders on a basis such that such income or gain is not taxable to
shareholders in the calendar year in which it was earned by the Fund.
Furthermore, dividends declared in October, November, or December payable to
shareholders of record on a specified date in such a month and paid in the
following January will be treated as having been paid by the Fund and received
by each shareholder in December. Under this rule, therefore, shareholders may be
taxed in one year on dividends or distributions actually received in January of
the following year.
 
Distributions of net investment income or net long-term capital gains will have
the effect of reducing the net asset value of the Fund's shares by the amount of
the distribution. If the net asset value is reduced
 
                                      -20-
 



<PAGE>
<PAGE>
below a shareholder's cost, the distribution will nonetheless be taxable as
described above, even if the distribution represents a return of invested
capital. Investors should consider the tax implications of buying shares just
prior to a distribution, when the price of shares may reflect the amount of the
forthcoming distribution.
 
If a correct and certified taxpayer identification number is not on file, the
Fund is required, subject to certain exemptions, to withhold 31% of certain
payments made or distributions declared to non-corporate shareholders.
Shareholders should be aware that, under applicable regulations, the Fund may be
fined up to $50 annually for each account for which a certified taxpayer
identification number is not provided. In the event that such a fine is imposed
with respect to any uncertified account in any year, a corresponding charge may
be made against that account.
 
This discussion of tax consequences is based on U.S. federal tax laws in effect
on the date of this Prospectus. These laws and regulations are subject to change
by legislative or administrative action, possibly with retroactive effect.
Investors are urged to consult their own tax advisors with respect to specific
questions as to federal taxes and with respect to the applicability of state or
local taxes. See 'Taxes' in the SAI.
 
ADDITIONAL INFORMATION
 
The Fund will send its shareholders annual and semi-annual reports. The
financial statements appearing in annual reports will be audited by independent
accountants. Shareholders also will be sent confirmations of each purchase and
redemption and periodic statements reflecting all account activity, including
dividends and any distributions whether reinvested in additional shares or paid
in cash.
 
Shareholders of certain Eligible Institutions may be given the privilege to
initiate transactions automatically by telephone upon opening an account.
However, an investor should be aware that a transaction authorized by telephone
and reasonably believed to be genuine by the Company, the Branch, the Eligible
Institution, the Transfer Agent or the Distributor may subject the investor to
risk of loss if such instruction is subsequently found not to be genuine. The
Company and its service providers will employ reasonable procedures, including
requiring investors to give a form of personal identification and tape recording
of telephonic instructions, to confirm that telephonic instructions by investors
are genuine; if it does not, it or the service provider may be liable for any
losses due to unauthorized or fraudulent instructions.
 
The Fund may make historical performance information available and may compare
its performance to other investments or relevant indices, including data from
Lipper Analytical Services, Inc., Micropal Inc., Morningstar Inc., Ibbotson
Associates, S&P 500 Index, the Dow Jones Average, the Frank Russell Indices, the
Financial Times World Stock Index and other industry publications.
 
The Fund may advertise 'total return'. The total return shows what an investment
in the Fund would have earned over a specified period of time (one, five or ten
years or since commencement of operations, if less) assuming that all Fund
distributions and dividends were reinvested on the reinvestment dates and less
all recurring fees during the period and assuming the redemption of such
investment at the end of each period. This method of calculating total return is
required by regulations of the SEC. Total return data similarly calculated,
unless otherwise indicated, over other specified periods of time may also be
used. All performance figures are based on historical earnings and are not
intended to indicate future performance. Performance information may be obtained
by clients of an Eligible Institution by calling the Eligible Institution and
other shareholders may address their inquiries to the Transfer Agent.

GENERAL
 
   

     UBS Private Investor Funds, Inc. (the 'Company') is an open-end management
investment company organized as a series fund. The Company is currently
authorized to issue shares in eight series, seven of which are described in this
Statement of Additional Information ('SAI'). These seven series (each a 'Fund'
and collectively, the 'Funds') consist of: UBS Bond Fund, UBS International
Equity Fund, UBS Institutional International Equity Fund, UBS U.S. Equity Fund,
UBS Small Cap Fund, UBS Large Cap Growth Fund and UBS High Yield Bond Fund. The
Company, a Maryland corporation, was organized on November 16, 1995. The
Company's executive offices are located at 200 Clarendon Street, Boston,
Massachusetts 02116.

    
 
   

     This SAI describes the investment objective and policies, management and
operations of each Fund to enable investors to determine if the Funds suit their
investment needs. Each Fund employs a two-tier master-feeder structure. As more
fully described herein, each Fund invests substantially all of its assets in a
corresponding series of a separate trust having the same investment objective as
that Fund. Each Trust series will in turn directly invest in securities
consistent with its investment objective. See 'Master-Feeder Structure' in the
Prospectus.

    
 
   

     UBS Investor Portfolios Trust, a master trust formed under New York law
(the 'Trust'), was organized on February 9, 1996, and is an open-end management
investment company. The Declaration of Trust of the Trust permits the Board of
Trustees of the Trust (the 'Trustees') to issue interests in one or more
subtrusts or 'series' (each a 'Portfolio' and collectively, the 'Portfolios').
To date, the Trust has established six Portfolios: UBS Bond Portfolio; UBS U.S.
Equity Portfolio; UBS International Equity Portfolio; UBS Small Cap Portfolio;
UBS Large Cap Growth Portfolio and UBS High Yield Bond Portfolio. UBS Bond Fund
invests in UBS Bond Portfolio; UBS U.S. Equity Fund invests in UBS U.S. Equity
Portfolio; UBS International Equity Fund and UBS Institutional International
Equity Fund invest in UBS International Equity Portfolio. UBS Small Cap Fund
invests in UBS Small Cap Portfolio; UBS Large Cap Growth Fund invests in UBS
Large Cap Growth Portfolio; and UBS High Yield Bond Fund invests in UBS High
Yield Bond Portfolio. Where appropriate, references to a Fund refer to that Fund
acting through its corresponding Portfolio.

    
 
     This SAI provides additional information with respect to each Fund, and
should be read in conjunction with that Fund's current Prospectus. Capitalized
terms not otherwise defined in this SAI have the meanings accorded to them in
the Fund's Prospectus.
 
INVESTMENT OBJECTIVES AND POLICIES
 
   

     UBS BOND FUND (the 'Bond Fund') is designed for investors seeking a higher
total return from a portfolio of debt securities issued by foreign and domestic
companies than that generally available from a portfolio of short-term
obligations in exchange for some risk of capital. Although the net asset value
of the Bond Fund will fluctuate, the Bond Fund attempts to conserve the value of
its investments to the extent consistent with its objective. The Bond Fund
attempts to achieve its objective by investing all of its investable assets in
UBS Bond Portfolio (the 'Bond Portfolio'), a series of the Trust having the same
investment objective as the Bond Fund. The Bond Portfolio attempts to achieve
its investment objective by investing primarily in the corporate and government
debt obligations and related securities described in the Prospectus and this
SAI.

    
 
   

     UBS HIGH YIELD BOND FUND (the 'High Yield Bond Fund') is designed for
investors seeking higher current income from a portfolio of higher-yielding,
lower-rated debt securities issued by domestic and foreign companies than
generally available from a portfolio of higher-rated obligations in exchange for
assuming additional risk of capital. The High Yield Bond Fund attempts to
achieve its objective by investing all of its investable assets in UBS High
Yield Bond Portfolio (the 'High Yield Bond Portfolio'), a series of the Trust
having the same investment objective as the High Yield Bond Fund. The High Yield
Bond Portfolio will also seek capital appreciation when consistent with high
current income by investing in securities benefiting from declines in long-term
interest rates or improvements in credit quality.

    
 
     UBS U.S. EQUITY FUND (the 'U.S. Equity Fund') is designed for investors
seeking long-term capital appreciation and the potential for a high level of
current income with lower investment risk and
 
                                     SAI-1

<PAGE>

volatility than is normally available from common stock funds. The U.S. Equity
Fund attempts to achieve its investment objective by investing all of its
investable assets in UBS U.S. Equity Portfolio (the 'U.S. Equity Portfolio'), a
series of the Trust having the same investment objective as the U.S. Equity
Fund.
 
     Under normal circumstances, at least 80% of the U.S. Equity Portfolio's
assets will be invested in income-producing domestic equity securities,
including dividend-paying common stocks and securities that are convertible into
common stocks. The U.S. Equity Portfolio's primary investments are the common
stocks of established, high-quality U.S. corporations.
 
   

     UBS INTERNATIONAL EQUITY FUND (the 'International Equity Fund') is designed
for investors who want to participate in the risks and returns associated with
investing in equity securities issued by foreign corporations but who may not be
prepared to meet the minimum investment requirements established by the UBS
Institutional International Equity Fund. The International Equity Fund attempts
to achieve its investment objective by investing all its investable assets in
the UBS International Equity Portfolio (the 'International Equity Portfolio'), a
series of the Trust having the same investment objective as the International
Equity Fund.

    
 
   

     The International Equity Portfolio seeks to achieve its investment
objective by investing primarily in the equity securities of foreign
corporations, consisting of common stocks and other securities with equity
characteristics such as preferred stocks, warrants, rights and convertible
securities. Under normal circumstances, the International Equity Portfolio
expects to invest at least 65% of its total assets in such securities. It does
not intend to invest in U.S. securities (other than short-term instruments),
except temporarily, when extraordinary circumstances prevailing at the same time
in a significant number of developed foreign countries render investments in
such countries inadvisable.

    
 
   

     UBS INSTITUTIONAL INTERNATIONAL EQUITY FUND (the 'Institutional
International Equity Fund') is designed for institutional and certain other
investors who want to participate in the risks and returns associated with
investing in equity securities issued by foreign corporations. The Institutional
International Equity Fund attempts to achieve its investment objective by
investing all its investable assets in the International Equity Portfolio, a
series of the Trust having the same investment objective as the Institutional
International Equity Fund.

    
 
   

     The International Equity Portfolio seeks to achieve its investment
objective by investing primarily in the equity securities of foreign
corporations, consisting of common stocks and other securities with equity
characteristics such as preferred stocks, warrants, rights and convertible
securities. Under normal circumstances, the International Equity Portfolio
expects to invest at least 65% of its total assets in such securities. It does
not intend to invest in U.S. securities (other than short-term instruments),
except temporarily, when extraordinary circumstances prevailing at the same time
in a significant number of developed foreign countries render investments in
such countries inadvisable.

    
 
   

     UBS SMALL CAP FUND (the 'Small Cap Fund') is designed for investors seeking
long-term capital appreciation from a portfolio of common stocks and other
equity securities of small capital growth companies believed to offer investors
above average potential for capital appreciation. 'Small capital' companies are
companies that have stock market capitalizations at the time of initial purchase
within the market capitalization range of those stocks on the Russell 2000
Index. 'Growth' companies are generally rapidly growing companies and may
include companies still in the development stage or older companies that appear
to be entering a new stage of growth owing to factors such as management changes
or new technology, products or markets. It may also include providers of
products or services with a high unit volume growth rate. The Small Cap Fund
attempts to achieve its objective by investing all of its investable assets in
UBS Small Cap Portfolio (the 'Small Cap Portfolio'), a series of the Trust
having the same investment objective as the Small Cap Fund.

    
 
   

     UBS LARGE CAP GROWTH FUND (the 'Large Cap Growth Fund') is designed for
investors seeking long-term capital appreciation from a portfolio of common
stocks and other equity securities of large capital growth companies. 'Large
capital' companies are companies whose stock market capitalizations at the time
of initial purchase are within the market capitalization range of those stocks
on the Standard & Poor's 500 Index. 'Growth' companies generally include
companies with the potential for above-average earnings and cash flow growth or
meaningful increases in underlying asset values over time. The Large

investable assets in UBS Large Cap Growth Portfolio (the 'Large Cap Growth
Portfolio'), a series of the Trust having the same investment objective as the
Large Cap Growth Fund.

    
 
MONEY MARKET INSTRUMENTS

     As discussed in the Prospectus, each Fund may invest in money market
instruments to the extent consistent with its investment objective and policies.
A description of the various types of money market instruments that may be
purchased appears below. See 'Quality and Diversification Requirements'.
 
     U.S. TREASURY SECURITIES. Each Fund may invest in direct obligations of the
U.S. Treasury, including Treasury Bills, Notes and Bonds, all of which are
backed as to principal and interest payments by the full faith and credit of the
United States.
 
     ADDITIONAL U.S. GOVERNMENT OBLIGATIONS. Each Fund may invest in obligations
issued or guaranteed by U.S. Government agencies or instrumentalities. These
obligations may or may not be backed by the 'full faith and credit' of the
United States. In the case of securities not backed by the full faith and credit
of the United States, each Fund must look principally to the federal agency
issuing or guaranteeing the obligation for ultimate repayment, and may not be
able to assert a claim against the United States itself in the event the agency
or instrumentality does not meet its commitments. Securities in which each Fund
may invest that are not backed by the full faith and credit of the United States
include, but are not limited to, obligations of the Tennessee Valley Authority,
the Federal Home Loan Mortgage Corporation and the U.S. Postal Service, each of
which has the right to borrow from the U.S. Treasury to meet its obligations,
and the obligations of the Federal Farm Credit System and the Federal Home Loan
Banks, both of whose obligations may be satisfied only by the individual credits
of each issuing agency. Securities that are backed by the full faith and credit
of the United States include obligations of the Government National Mortgage
Association, the Farmers Home Administration and the Export-Import Bank.
 
   

     BANK OBLIGATIONS. Each Fund, unless otherwise noted in the Prospectus or
below, may invest in negotiable certificates of deposit, time deposits and
bankers' acceptances of (i) banks, savings and loan associations and savings
banks that have more than $2 billion in total assets (the 'Asset Limitation')
and are organized under the laws of the United States or any state, (ii) foreign
branches of these banks or of foreign banks of equivalent size (Euros) and (iii)
U.S. branches of foreign banks of equivalent size (Yankees). The Asset
Limitation is not applicable to either the Institutional International Equity
Fund or the International Equity Fund (collectively, the 'International Equity
Funds'). See 'Foreign Investments'. No Fund will invest in obligations for which
the Adviser, defined below (or the Sub-Adviser, defined below, in the case of
the International Equity Funds, the Small Cap Fund, the Large Cap Growth Fund
and the High Yield Bond Fund), or any of its affiliated persons, is the ultimate
obligor or accepting bank. Each Fund may also invest in obligations of
international banking institutions designated or supported by national
governments to promote economic reconstruction, development or trade between
nations (e.g., the European Investment Bank, the Inter-American Development Bank
or the World Bank).

    
 
   

     COMMERCIAL PAPER. Each Fund may invest in commercial paper, including
Master Demand obligations. Master Demand obligations are obligations that
provide for a periodic adjustment in the interest rate paid and permit daily
changes in the amount borrowed. Master Demand obligations are governed by
agreements between the issuer and Union Bank of Switzerland (the 'Bank'), New
York Branch (the 'Branch' or the 'Adviser'), and in the case of the
International Equity Funds, UBS International Investment London Limited ('UBSII'
or the 'Sub-Adviser'), and in the case of the Small Cap Fund, the Large Cap
Growth Fund and the High Yield Bond Fund, UBS Asset Management (New York), Inc.,
acting as agent, for no additional fee, in its capacity as investment adviser*
to the Portfolios and as fiduciary for other clients for whom it exercises
investment discretion. The monies loaned to the borrower come from accounts
managed by the Adviser*, or its affiliates, pursuant to arrangements with
 
- ------------
    
   

     * Unless otherwise noted, references to the Adviser in the context of the
International Equity Portfolio, Small Cap Portfolio, Large Cap Growth Portfolio
and the High Yield Bond Portfolio refer to the Adviser and/or the Sub-Advisers,
as appropriate.

<PAGE>

such accounts. Interest and principal payments are credited to such accounts.
The Adviser*, acting as a fiduciary on behalf of its clients, has the right to
increase or decrease the amount provided to the borrower under an obligation.
The borrower has the right to pay without penalty all or any part of the
principal amount then outstanding on an obligation together with interest to the
date of payment. Because these obligations typically provide that the interest
rate is tied to the Federal Reserve commercial paper composite rate, the rate on
Master Demand obligations is subject to change. Repayment of a Master Demand
obligation to participating accounts depends on the ability of the borrower to
pay the accrued interest and principal of the obligation on demand, which is
continuously monitored by the Adviser*. Because Master Demand obligations
typically are not rated by credit rating agencies, the Portfolios may invest in
such unrated obligations only if at the time of an investment the obligation is
determined by the Adviser* to have a credit quality which satisfies a
Portfolio's quality restrictions. See 'Quality and Diversification
Requirements'. Although there is no secondary market for Master Demand
obligations, such obligations are considered to be liquid because they are
payable upon demand. The Portfolios do not have any specific percentage
limitation on investments in Master Demand obligations.
 
     REPURCHASE AGREEMENTS. Each Portfolio may enter into repurchase agreements
with brokers, dealers or banks that meet the credit guidelines approved by the
Trustees. In a repurchase agreement, a Portfolio buys a security from a seller
that has agreed to repurchase the same security at a mutually agreed upon date
and price. The resale price normally is in excess of the purchase price,
reflecting an agreed upon interest rate. This interest rate is effective for the
period of time the Portfolio is invested in the agreement and is not related to
the coupon rate on the underlying security. A repurchase agreement may also be
viewed as a fully collateralized loan of money by the Portfolio to the seller.
The period of these repurchase agreements will usually be short, from overnight
to one week, and at no time will the Portfolio invest in repurchase agreements
for more than thirteen months. The securities that are subject to repurchase
agreements, however, may have maturity dates in excess of thirteen months from
the effective date of the repurchase agreement. The Portfolios will always
receive securities as collateral whose market value is, and during the entire
term of the agreement remains, at least equal to 100% of the dollar amount
invested by the Portfolios in each agreement plus accrued interest, and the
Portfolios will make payment for such securities only upon physical delivery or
upon evidence of book entry transfer to the account of the Custodian. If the
seller defaults, a Portfolio might incur a loss if the value of the collateral
securing the repurchase agreement declines and might incur disposition costs in
connection with liquidating the collateral. In addition, if bankruptcy
proceedings are commenced with respect to the seller of the security,
realization of proceeds upon disposition of the collateral by the Portfolio may
be delayed or limited.
 
CORPORATE BONDS AND OTHER DEBT SECURITIES
 
   

     Each Portfolio, with the exception of the Bond Portfolio and the High Yield
Bond Portfolio, may invest in other debt securities with remaining effective
maturities of less than thirteen months, including without limitation corporate
and foreign bonds, asset-backed securities and other obligations described in
the Prospectus or this SAI.

    
 
   

     As discussed in the Prospectus, the Bond Portfolio and the High Yield Bond
Portfolio, may invest in bonds and other debt securities of domestic and foreign
issuers to the extent consistent with their investment objectives and policies.
A description of these investments appears in the Prospectus and below. See
'Quality and Diversification Requirements'. For information on short-term
investments in these securities, see 'Money Market Instruments'.

    
 
     ASSET-BACKED SECURITIES. Asset-backed securities directly or indirectly
represent a participation interest in, or are secured by or payable from, a
stream of payments generated by particular assets such as mortgages, motor
vehicles or credit card receivables. Payments of principal and interest may be
guaranteed up to certain amounts and for a certain time period by a letter of
credit issued by a financial institution unaffiliated with the entities issuing
the securities. The asset-backed securities in which a Portfolio may invest are
subject to the Portfolio's overall credit requirements. However, asset-backed
securities, in general, are subject to certain risks. These risks include the
prepayment of the debtor's obligation and the creditor's limited interests in
applicable collateral. For example, credit card debt
 
                                     SAI-4
 

<PAGE>
<PAGE>

receivables are generally unsecured and the debtors are entitled to the
protection of a number of state and federal consumer credit laws, many of which
give such debtors the right to set off certain amounts owed on credit card debt
thereby reducing the balance due. Additionally, if the letter of credit is
exhausted, holders of asset-backed securities may also experience delays in
payments or losses if the full amounts due on underlying sales contracts are not
realized. Because asset-backed securities are relatively new, the market
experience in these securities is limited and the market's ability to sustain
liquidity through all phases of the market cycle has not been tested.
 
EQUITY INVESTMENTS
 
   

     As discussed in the Prospectus, the U.S. Equity, International Equity,
Small Cap and Large Cap Growth Portfolios invest primarily in equity securities
consisting of common stocks and other securities with equity characteristics.
The securities in which these Portfolios invest include those listed on domestic
and foreign securities exchanges or traded on over-the-counter markets as well
as certain restricted or unlisted securities. A discussion of the various types
of equity investments that may be purchased by these Portfolios appears in the
Prospectus and below. See 'Quality and Diversification Requirements'.

    
 
     EQUITY SECURITIES. The common stocks in which these Portfolios may invest
include the common stocks of any class or series of corporations or any similar
equity interests such as trust or partnership interests. The Portfolios' equity
investments include preferred stocks, warrants, rights and convertible
securities. These investments may or may not pay dividends and may or may not
carry voting rights. Common stock occupies the most junior position in a
company's capital structure.
 
     The convertible securities in which the Portfolios may invest include debt
securities or preferred stocks that may be converted into common stock or that
carry the right to purchase common stock. Convertible securities entitle the
holder to exchange the securities for a specified number of shares of common
stock, usually of the same company, at specified prices within a certain period
of time.
 
     The terms of a convertible security determine its ranking in a company's
capital structure. In the case of subordinated convertible debentures, the
holders' claims on assets and earnings are subordinated to the claims of other
creditors, but are senior to the claims of preferred and common stockholders. In
the case of convertible preferred stock, the holders' claims on assets and
earnings are subordinated to the claims of all creditors, but are senior to the
claims of common stockholders.
 
FOREIGN INVESTMENTS
 
   

     The International Equity Portfolio makes substantial investments in
companies based in foreign countries. The Bond and High Yield Bond Portfolios
may also invest in certain foreign securities. Neither the Bond Portfolio nor
the High Yield Bond Portfolio expect to invest more than 25% of their total
assets, at the time of purchase, in securities of foreign issuers. Foreign
investments may be made directly in the securities of foreign issuers or in the
form of American Depository Receipts ('ADRs') Global Depository Receipts
('GDRs') or European Depository Receipts ('EDRs'). Generally, ADRs, GDRs and
EDRs are receipts issued by a bank or trust company that evidence ownership of
underlying securities issued by a foreign corporation and that are designed for
use in the domestic, in the case of ADRs, European, in the case of EDRs, or
domestic and European in the case of GDRs, securities markets.

    
 
   

     Because investments in foreign securities may involve foreign currencies,
the value of the International Equity, Bond and High Yield Bond Portfolios'
assets as measured in U.S. dollars may be affected, favorably or unfavorably, by
changes in currency rates and in exchange control regulations, including
currency blockage. The Bond, High Yield Bond and International Equity Portfolios
may enter into foreign currency exchange transactions in connection with the
settlement of foreign securities transactions or to manage their currency
exposure related to foreign investments. The Portfolios will not enter into such
transactions for speculative purposes. For a description of the risks associated
with investing in foreign securities, see 'Additional Investment Information and
Risk Factors' in the Prospectus.

ADDITIONAL INVESTMENTS
 
   

     WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. Each Portfolio may purchase
securities on a when-issued or delayed delivery basis. For example, delivery of
and payment for these securities can take place a month or more after the date
of the purchase commitment. The purchase price and the interest rate payable, if
any, on the securities are fixed on the purchase commitment date or at the time
the settlement date is fixed. The value of such securities is subject to market
fluctuation and no interest accrues to a Portfolio until settlement takes place.
At the time a Portfolio makes the commitment to purchase securities on a
when-issued or delayed delivery basis, it will record the transaction, reflect
the value of such securities each day in determining its net asset value and, if
applicable, calculate the maturity for the purposes of average maturity from
that date. At the time of settlement, a when-issued security may be valued at
less than the purchase price. To facilitate such acquisitions, each Portfolio
will maintain with the Custodian a segregated account with liquid securities, in
an amount at least equal to the value of such commitments. On delivery dates for
such transactions, each Portfolio will meet its obligations from maturities or
sales of the securities held in the segregated account and/or from cash flow. If
a Portfolio chooses to dispose of the right to acquire a when-issued security
prior to its acquisition, it could, as with the disposition of any other
portfolio obligation, incur a gain or loss due to market fluctuation. It is the
current policy of each Portfolio not to enter into when-issued commitments
exceeding in the aggregate 15% of the market value of that Portfolio's total
assets, less liabilities (excluding the obligations created by when-issued
commitments).

    
 
     INVESTMENT COMPANY SECURITIES. Securities of other investment companies may
be acquired by each Fund to the extent that such purchases are consistent with
that entity's investment objectives and restrictions and are permitted under the
Investment Company Act of 1940, as amended (the '1940 Act'). The 1940 Act
requires that, as determined immediately after a purchase is made, (i) not more
than 5% of the value of the Fund's total assets will be invested in the
securities of any one investment company, (ii) not more than 10% of the value of
the Fund's total assets will be invested in securities of investment companies
as a group and (iii) not more than 3% of the outstanding voting stock of any one
investment company will be owned by the Fund, provided, however, that a Fund may
invest all of its investable assets in an open-end investment company having the
same investment objective as that Fund. As a shareholder of another investment
company, a Fund would bear, along with other shareholders, its pro rata portion
of the other investment company's expenses, including advisory fees. These
expenses would be in addition to the expenses that such a Fund would bear in
connection with its own operations.
 
     REVERSE REPURCHASE AGREEMENTS. Each Portfolio may enter into reverse
repurchase agreements. In a reverse repurchase agreement, the Portfolio sells a
security and agrees to repurchase the same security at a mutually agreed upon
date and price. For purposes of the 1940 Act, reverse repurchase agreements are
considered borrowings by the Portfolio and, therefore, a form of leverage. The
Portfolios will invest the proceeds of borrowings under reverse repurchase
agreements. In addition, the Portfolios will enter into a reverse repurchase
agreement only when the interest income to be earned from the investment of the
proceeds is greater than the interest expense of the repurchase agreement. The
Portfolios will not invest the proceeds of a reverse repurchase agreement for a
period that exceeds the term of the reverse repurchase agreement. The
limitations on each Portfolio's use of reverse repurchase agreements are
discussed under 'Investment Restrictions' below. Each Portfolio will establish
and maintain with the Custodian a separate account with a portfolio of
securities in an amount at least equal to its obligations under its reverse
repurchase agreements.
 
     MORTGAGE DOLLAR ROLL TRANSACTIONS. The Bond Portfolio may engage in
mortgage dollar roll transactions with respect to mortgage securities issued by
the Government National Mortgage Association, the Federal National Mortgage
Association and the Federal Home Loan Mortgage Corporation. In a mortgage dollar
roll transaction, the Portfolio sells a mortgage backed security and
simultaneously agrees to repurchase a similar security on a specified future
date at an agreed upon price. During the roll period, the Portfolio will not be
entitled to receive any interest or principal paid on the securities sold. The
Portfolio is compensated for the lost interest on the securities sold by the
difference between the sales price and the lower price for the future repurchase
as well as by the interest earned on the reinvestment of the sales proceeds. The
Portfolio may also be compensated by receipt of a
 
                                     SAI-6
 

<PAGE>
<PAGE>

commitment fee. When the Portfolio enters into a mortgage dollar roll
transaction, liquid assets in an amount sufficient to pay for the future
repurchase are segregated with its Custodian. Mortgage dollar roll transactions
are considered reverse repurchase agreements for purposes of the Portfolio's
investment restrictions.
 
     SECURITIES LENDING. Each Portfolio may lend its securities if such loans
are secured continuously by cash or equivalent collateral or by a letter of
credit in favor of the Portfolio at least equal at all times to 100% of the
market value of the securities loaned, plus accrued interest. While such
securities are on loan, the borrower will pay the Portfolio any income accruing
thereon. Loans will be subject to termination by the Portfolios in the normal
settlement time, generally three business days after notice or by the borrower
on one day's notice. Borrowed securities must be returned when the loan is
terminated. Any gain or loss in the market price of the borrowed securities that
occurs during the term of the loan inures to the Portfolio and its respective
investors. The Portfolios may pay reasonable finder's and custodial fees in
connection with a loan. In addition, the Portfolios will consider all facts and
circumstances including the creditworthiness of the borrowing financial
institution, and the Portfolios will not make any loans in excess of one year.
The Portfolios will not lend their securities to any officer, Trustee, Director,
employee, or affiliate or placement agent of the Company, the Trust, or to the
Adviser, Sub-Adviser, Administrator or Distributor or any affiliate thereof,
unless otherwise permitted by applicable law.
 
     PRIVATELY PLACED AND CERTAIN UNREGISTERED SECURITIES. The Portfolios may
invest in privately placed, restricted, Rule 144A or other unregistered
securities as described in the Prospectus.
 
     As to illiquid investments, a Portfolio is subject to a risk that it might
not be able to sell such securities at a price that the Portfolio deems
respective of their value. Where an illiquid security must be registered under
the Securities Act of 1933, as amended (the 'Securities Act'), before it may be
resold, the Portfolio may be obligated to pay all or part of the registration
expenses and a considerable period may elapse between the time the Portfolio
decides to sell and the time the Portfolio is permitted to sell under an
effective registration statement. If, during such a period, adverse market
conditions develop, the Portfolio might obtain a less favorable price than that
which prevailed when it decided to sell. When the Portfolios value these
securities, they will take into account the illiquid nature of these
instruments.
 
QUALITY AND DIVERSIFICATION REQUIREMENTS
 
   

     Each Portfolio intends to meet the diversification requirements of the 1940
Act. To meet these requirements, 75% of the Portfolio's assets are subject to
the following fundamental limitations: (1) the Portfolio may not invest more
than 5% of its total assets in the securities of any one issuer, except
obligations of the U.S. Government, its agencies and instrumentalities and (2)
the Portfolio may not own more than 10% of the outstanding voting securities of
any one issuer. As for the 25% of a Portfolio's assets not subject to the
limitation described above, there is no limitation on investment of these assets
under the 1940 Act, so that all of such assets may be invested in securities of
any one issuer. Investments not subject to the limitations described above could
involve an increased risk to a Portfolio should an issuer, or a state or its
related entities, be unable to make interest or principal payments or should the
market value of such securities decline. See 'Investment Restrictions'.
    
 
   
     BOND PORTFOLIO. The Bond Portfolio invests principally in a diversified
portfolio of 'high grade' and 'investment grade' securities. Investment grade
debt is rated, on the date of investment, within the four highest ratings of
Moody's Investors Service, Inc. ('Moody's'), currently Aaa, Aa, A and Baa, or of
Standard & Poor's Ratings Group ('Standard & Poor's'), currently AAA, AA, A and
BBB. High grade debt is rated, on the date of the investment, within the two
highest categories of the above ratings. The Bond Portfolio may also invest up
to 5% of its total assets in securities which are 'below investment grade'. Such
securities must be rated, on the date of investment, Ba by Moody's or BB by
Standard & Poor's. The Portfolio may invest in debt securities that are not
rated or other debt securities to which these ratings are not applicable, if in
the opinion of the Adviser, such securities are of comparable quality to the
rated securities discussed above. In addition, at the time the Portfolio invests
in any commercial paper, bank obligation or repurchase agreement, the issuer
must have outstanding debt rated A or higher by Moody's or Standard & Poor's,
the issuer's parent corporation, if any, must have outstanding
    
 
                                     SAI-7
 

<PAGE>
<PAGE>

commercial paper rated Prime-1 by Moody's or A-1 by Standard & Poor's, or if no
such ratings are available, the investment must be of comparable quality in the
Adviser's opinion.
 
   
     HIGH YIELD BOND PORTFOLIO. The High Yield Bond Portfolio invests primarily
in lower-rated securities, commonly known as 'junk bonds.' Lower rated
securities include securities rated lower than Baa by Moody's or BBB or lower by
Standard & Poor's. Securities rated lower than Baa or BBB are considered to be
of poor standing and predominantly speculative. The High Yield Bond Portfolio
may invest up to 10% of its assets in securities rated below Caa by Moody's or
CCC by Standard & Poor's (including securities in the lowest rating category of
either rating agency) or if unrated, determined by the Adviser* to be of
comparable quality. The market values of these securities tend to be more
sensitive to individual corporate developments and changes in economic
conditions than higher-quality securities.
    
 
   
     U.S. EQUITY, INTERNATIONAL EQUITY, SMALL CAP AND LARGE CAP GROWTH
PORTFOLIOS. The U.S. Equity, International Equity, Small Cap and Large Cap
Growth Portfolios may invest in convertible debt securities for which there are
no specific quality requirements. In addition, at the time the Portfolios invest
in any commercial paper, bank obligation or repurchase agreement, the issuer
must have outstanding debt rated A or higher by Moody's or Standard & Poor's,
the issuer's parent corporation, if any, must have outstanding commercial paper
rated Prime-1 by Moody's or A-1 by Standard & Poor's, or if no such ratings are
available, the investment must be of comparable quality in the Adviser's*
opinion. At the time the Portfolios invest in any other short-term debt
securities, they must be rated A or higher by Moody's or Standard & Poor's, or
if unrated, the investment must be of comparable quality in the Adviser's*
opinion.
    
 
     In determining whether a particular unrated security is a suitable
investment, the Adviser* takes into consideration asset and debt service
coverage, the purpose of the financing, the history of the issuer, existence of
other rated securities of the issuer, and other relevant conditions, such as
comparability to other issuers.
 
OPTIONS AND FUTURES TRANSACTIONS
 
     EXCHANGE-TRADED AND OVER-THE-COUNTER OPTIONS. All options purchased or sold
by the Portfolios will be exchange traded or will be purchased or sold by
securities dealers ('over-the-counter' or 'OTC options') that meet
creditworthiness standards approved by the Trustees. Exchange-traded options are
obligations of the Options Clearing Corporation. In OTC options, the Portfolio
relies on the dealer from which it purchased the option to perform if the option
is exercised. Thus, when a Portfolio purchases an OTC option, it relies on the
dealer from which it purchased the option to make or take delivery of the
underlying securities. Failure by the dealer to do so would result in the loss
of the premium paid by the Portfolio as well as loss of the expected benefit of
the transaction. To the extent that a Portfolio may trade in foreign options,
such options may be effected through local clearing organizations.
 
   
     The staff of the Securities and Exchange Commission (the 'SEC') has taken
the position that, in general, purchased OTC options and the underlying
securities used to cover written OTC options are illiquid securities. However, a
Portfolio may treat as liquid the underlying securities used to cover written
OTC options, provided it has arrangements with certain qualified dealers who
agree that the Portfolio may repurchase any option it writes for a maximum price
to be calculated by a predetermined formula. In these cases, the OTC option
itself would only be considered illiquid to the extent that the maximum
repurchase price under the formula exceeds the intrinsic value of the option.
    
 
     FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS. The Portfolios are
permitted to enter into futures and options transactions and may purchase or
sell futures contracts and purchase put and call options, including put and call
options on futures contracts. Futures contracts obligate the buyer to take and
the seller to deliver at a future date a specified quantity of a financial
instrument or an amount of cash based on the value of a securities index or
financial instrument. Currently, futures contracts are

     * Unless otherwise noted, references to the Adviser in the context of the
International Equity Portfolio, the Small Cap Portfolio, the Large Cap Growth
Portfolio and the High Yield Bond Portfolio refer to the Adviser and/or the
Sub-Adviser, as appropriate.
    
 
                                     SAI-8

<PAGE>

available on various types of fixed-income securities including, but not
limited, to U.S. Treasury bonds, notes and bills, Eurodollar certificates of
deposit and on indices of fixed income and equity securities.
 
     Unlike a futures contract, which requires the parties to buy and sell a
security or make a cash settlement payment based on changes in a financial
instrument or securities index on an agreed date, an option on a futures
contract entitles its holder to decide on or before a future date whether to
enter into such a contract. If the holder decides not to exercise its option,
the holder may close out the option position by entering into an offsetting
transaction or may decide to let the option expire and forfeit the premium
thereon. The purchaser of an option on a futures contract pays a premium for the
option but makes no initial margin payments or daily payments of cash in the
nature of 'variation' margin payments to reflect the change in the value of the
underlying contract as does a purchaser or seller of a futures contract.
 
     The seller of an option on a futures contract receives the premium paid by
the purchaser and may be required to pay initial margin. Amounts equal to the
initial margin and any additional collateral required on futures contracts and
on any options on futures contracts sold by a Portfolio are paid by the
Portfolio into a segregated account, in the name of the Futures Commission
Merchant, as required by the 1940 Act and the SEC's interpretations thereunder.
To the extent a Portfolio may trade in futures and options therein involving
foreign securities, such transactions may be effected according to local
regulations and business customs.
 
     COMBINED POSITIONS. The Portfolios may purchase and write options in
combination with each other, or in combination with futures or forward
contracts, to adjust the risk and return characteristics of the overall
position. For example, the Portfolios may write a call option at one strike
price and buy a call option at a lower price, in order to reduce the risk of the
written call option in the event of a substantial price increase. Because
combined positions involve multiple trades, they result in higher transaction
costs and may be more difficult to open and close out.
 
     CORRELATION OF PRICE CHANGES. Because there are a limited number of types
of exchange-traded options and futures contracts, it is likely that the
standardized options and futures contracts available will not exactly match a
Portfolio's current or anticipated investments. A Portfolio may invest in
options and futures contracts based on securities with different issuers,
maturities, or other characteristics from the securities in which it typically
invests, which involves a risk that the options or futures position will not
track the performance of the Portfolio's other investments.
 
     Options and futures contracts prices can also diverge from the prices of
their underlying instruments, even if the underlying instruments match the
Portfolio's investments well. Options and futures contracts prices are affected
by such factors as current and anticipated short-term interest rates, changes in
volatility of the underlying instrument, and the time remaining until expiration
of the contract, which may not affect security prices the same way. Imperfect
correlation may also result from differing levels of demand in the options and
futures markets and the securities markets, from structural differences in how
options and futures and securities are traded, or from imposition of daily price
fluctuation limits or trading halts. A Portfolio may purchase or sell options
and futures contracts with a greater or lesser value than the securities it
wishes to hedge or intends to purchase in order to attempt to compensate for
differences in volatility between the contract and the securities, although this
may not be successful in all cases. If price changes in a Portfolio's options or
futures positions are poorly correlated with its other investments, the
positions may fail to produce anticipated gains or result in losses that are not
offset by gains in other investments.
 
     LIQUIDITY OF OPTIONS AND FUTURES CONTRACTS. There is no assurance a liquid
market will exist for any particular option or futures contract at any
particular time even if the contract is traded on an exchange. In addition,
exchanges may establish daily price fluctuation limits for options and futures
contracts and may halt trading if a contract's price moves up or down more than
the limit in a given day. On volatile trading days when the price fluctuation
limit is reached or a trading halt is imposed, it may be impossible for a
Portfolio to enter into new positions or close out existing positions. If the
market for a contract is not liquid because of price fluctuation limits or
otherwise, it could prevent prompt liquidation of unfavorable positions, and
could potentially require a Portfolio to continue to hold a position until
delivery or expiration regardless of changes in its value. As a result, the
Portfolio's access to other assets
 
                                     SAI-9

<PAGE>

held to cover its options or futures positions could also be impaired. See
'Exchange Traded and Over-the-Counter Options' above for a discussion of the
liquidity of options not traded on an exchange.
 
     POSITION LIMITS. Futures exchanges can limit the number of futures and
options on futures contracts that can be held or controlled by an entity. If an
adequate exemption cannot be obtained, a Portfolio or the Adviser may be
required to reduce the size of its futures and options positions or may not be
able to trade a certain futures or options contract in order to avoid exceeding
such limits.
 
     ASSET COVERAGE FOR FUTURES CONTRACTS AND OPTIONS POSITIONS. The Portfolios
intend to comply with Section 4.5 of the regulations under the Commodity
Exchange Act, which limits the extent to which a Portfolio can commit assets to
initial margin deposits and option premiums. In addition, the Portfolios will
comply with guidelines established by the SEC with respect to coverage of
options and futures contracts by mutual funds, and if the guidelines so require,
will set aside appropriate liquid assets in a segregated custodial account in
the amount prescribed. Securities held in a segregated account cannot be sold
and will be considered illiquid securities while the futures contract or option
is outstanding, unless they are replaced with other suitable assets. As a
result, there is a possibility that the segregation of a large percentage of a
Portfolio's assets could impede portfolio management or the Portfolio's ability
to meet redemption requests or other current obligations.
 
INVESTMENT RESTRICTIONS
 
     The Funds have adopted the following fundamental and non-fundamental
investment restrictions (as defined and distinguished below); to the extent that
a fundamental policy and non-fundamental policy apply to a given investment
activity or strategy, the more restrictive policy shall govern.
 
     FUNDAMENTAL INVESTMENT RESTRICTIONS. The investment restrictions below have
been adopted by the Company's Board of Directors (the 'Board' or the
'Directors') with respect to each Fund and by the Trustees for each
corresponding Portfolio. Except where otherwise noted, these investment
restrictions are 'fundamental' policies which, under the 1940 Act, may not be
changed without the 'vote of a majority of the outstanding voting securities' of
the Fund or the Portfolio, as applicable, to which they relate. The 'vote of a
majority of the outstanding voting securities' under the 1940 Act is the lesser
of (a) 67% or more of the voting securities present at a shareholders' meeting
if the holders of more than 50% of the outstanding voting securities are present
or represented by proxy or (b) more than 50% of the outstanding voting
securities. Except as described below, whenever a Fund is requested to vote on a
change in the fundamental investment restrictions of its corresponding
Portfolio, the Company will hold a meeting of that Fund's shareholders and the
Company will cast that Fund's votes in the Portfolio in proportion to the votes
cast by that Fund's shareholders. However, subject to applicable statutory and
regulatory requirements, a Fund would not request a vote of its shareholders
with respect to (a) any proposal relating to its corresponding Portfolio, which
proposal, if made with respect to the Fund, would not require the vote of the
shareholders of the Fund, or (b) any proposal with respect to the Portfolio that
is identical in all material respects to a proposal that has previously been
approved by shareholders of the Fund. Any proposal submitted to holders in the
Portfolio, and that is not required to be voted on by shareholders of the Fund,
would nevertheless be voted on by the Trustees of the Fund.
 
     The investment restrictions of each Fund and its corresponding Portfolio
are identical, unless otherwise specified. Accordingly, references below to a
Fund also include that Fund's corresponding Portfolio unless the context
requires otherwise; similarly, references to a Portfolio also include the
corresponding Fund unless the context requires otherwise. As a matter of
fundamental policy, each Fund and Portfolio may not:
 
1.   Borrow money, except from banks for extraordinary or emergency purposes and
     then only in amounts up to one-third of the value of its total assets
     (including the amount borrowed), less liabilities (not including the
     amounts borrowed), or mortgage, pledge, or hypothecate any assets, except
     in connection with any permitted borrowing or reverse repurchase agreements
     (see Investment Restriction No. 7). It will not purchase securities while
     borrowings (including reverse repurchase agreements) exceed 5% of its net
     assets; provided, however, that it may increase its interest in an open-end
     management investment company with the same investment objective and
 
                                     SAI-10
 

<PAGE>
<PAGE>

     restrictions while such borrowings are outstanding and provided further
     that for purposes of this restriction, short-term credits necessary for the
     clearance of transactions are not considered borrowings. This borrowing
     provision facilitates the orderly sale of portfolio securities, for
     example, in the event of abnormally heavy redemption requests and is not
     for investment purposes. Collateral arrangements for premium and margin
     payments in connection with its hedging activities are not deemed to be a
     pledge of assets;
 
2.   Purchase the securities of an issuer if, immediately after such purchase,
     it owns more than 10% of the outstanding voting securities of such issuer;
     provided, however, that a Fund may invest all or part of its investable
     assets in an open-end management investment company with the same
     investment objective and restrictions. This limitation also shall not apply
     to investments of up to 25% of its total assets;
 
3.   Purchase the securities or other obligations of any one issuer if,
     immediately after such purchase, more than 5% of the value of its total
     assets would be invested in securities or other obligations of any one such
     issuer; provided, however, that a Fund may invest all or part of its
     investable assets in an open-end management investment company with the
     same investment objective and restrictions. This limitation shall not apply
     to securities issued or guaranteed by the U.S. Government, its agencies or
     instrumentalities or to investments of up to 25% of its total assets;
 
4.   Purchase securities or other obligations of issuers conducting their
     principal business activity in the same industry if, immediately after such
     purchase the value of its investments in such industry would exceed 25% of
     the value of its total assets; provided, however, that a Fund may invest
     all or part of its investable assets in an open-end management investment
     company with the same investment objective and restrictions. For purposes
     of industry concentration, there is no percentage limitation with respect
     to investments in U.S. Government securities;
 
5.   Make loans, except through the purchase or holding of debt obligations
     (including privately placed securities) or by entering into repurchase
     agreements or loans of portfolio securities;
 
   
6.   Purchase or sell real estate, commodities or commodities contracts or
     options thereon (except for its interest in hedging and certain other
     activities as described under 'Investment Objective(s) and Policies'),
     interests in oil, gas, or mineral exploration or development programs
     (including limited partnerships). In addition, neither the U.S. Equity
     Portfolio, the International Equity Portfolio, the Small Cap Portfolio, the
     Large Cap Growth Portfolio may purchase or sell real estate mortgage loans.
     The Bond Portfolio and High Yield Bond Portfolio, however, may purchase
     debt obligations secured by interests in real estate or issued by companies
     that invest in real estate or interests therein including real estate
     investment trusts ('REITs'); and the International Equity Portfolio, the
     U.S. Equity Portfolio, the Small Cap Portfolio and the Large Cap Growth
     Portfolio may purchase the equity securities or commercial paper issued by
     companies that invest in real estate or interests therein, including REITs;
    
 
7.   Issue any senior security, except as appropriate to evidence indebtedness
     that it is permitted to incur pursuant to Investment Restriction No. 1 and
     except that it may enter into reverse repurchase agreements, provided that
     the aggregate of senior securities, including reverse repurchase
     agreements, shall not exceed one-third of the market value of its total
     assets (including the amounts borrowed), less liabilities (excluding
     obligations created by such borrowings and reverse repurchase agreements).
     Hedging activities as described in 'Investment Objective(s) and Policies'
     shall not be considered senior securities for purposes hereof; or
 
8.   Act as an underwriter of securities.
 
   
     NON-FUNDAMENTAL INVESTMENT RESTRICTIONS -- ALL FUNDS. The investment
restrictions described below are non-fundamental policies of each Fund and its
corresponding Portfolio, and may be changed by their respective Directors and
Trustees without shareholder approval. These non-fundamental investment policies
provide that neither a Fund nor a Portfolio may:
    
 
1.   borrow money (including through reverse repurchase or forward roll
     transactions) for any purpose in excess of 5% of the Fund's total assets
     (taken at cost), except that the Fund may borrow for temporary or emergency
     purposes up to 1/3 of its assets;
 
                                     SAI-11
 

<PAGE>
<PAGE>

2.   pledge, mortgage or hypothecate for any purpose in excess of 10% of the
     Fund's total assets (taken at market value), provided that collateral
     arrangements with respect to options and futures, including deposits of
     initial deposit and variation margin, and reverse repurchase agreements are
     not considered a pledge of assets for purposes of this restriction;
 
3.   purchase any security or evidence of interest therein on margin, except
     that such short-term credit as may be necessary for the clearance of
     purchases and sales of securities may be obtained and except that deposits
     of initial deposit and variation margin may be made in connection with the
     purchase, ownership, holding or sale of futures;
 
4.   sell securities it does not own such that the dollar amount of such short
     sales at any one time exceeds 25% of the net equity of the Fund, and the
     value of securities of any one issuer in which the Fund is short exceeds
     the lesser of 2.0% of the value of the Fund's net assets or 2.0% of the
     securities of any class of any U.S. issuer, and provided that short sales
     may be made only in those securities which are fully listed on a national
     securities exchange or a foreign exchange (This provision does not include
     the sale of securities the Fund contemporaneously owns or where the Fund
     has the right to obtain securities equivalent in kind and amount to those
     sold, i.e., short sales against the box.) (The Fund has no current
     intention to engage in short selling.);
 
5.   invest for the purpose of exercising control or management;
 
6.   purchase securities issued by any investment company except by purchase in
     the open market where no commission or profit to a sponsor or dealer
     results from such purchase other than the customary broker's commission, or
     except when such purchase, though not made in the open market, is part of a
     plan of merger or consolidation; provided, however, that securities of any
     investment company will not be purchased for the Fund if such purchase at
     the time thereof would cause (a) more than 10% of the Fund's total assets
     (taken at the greater of cost or market value) to be invested in the
     securities of such issuers; (b) more than 5% of the Fund's total assets
     (taken at the greater of cost or market value) to be invested in any one
     investment company; or (c) more than 3% of the outstanding voting
     securities of any such issuer to be held for the Fund; provided further
     that, except in the case of a merger or consolidation, the Fund shall not
     purchase any securities of any open-end investment company unless (1) the
     Fund's investment adviser waives the investment advisory fee with respect
     to assets invested in other open-end investment companies and (2) the Fund
     incurs no sales charge in connection with that investment;
 
   
7.   invest more than 10% of the Fund's total assets (taken at the greater of
     cost or market value) in securities (excluding Rule 144A securities) that
     are restricted as to resale under the Securities Act;
    
 
   
8.   (except for the Small Cap Fund, Large Cap Growth Fund and High Yield Bond
     Fund) invest more than 15% of the Fund's net assets (taken at the greater
     of cost or market value) in securities that are issued by issuers which
     (including predecessors) have been in operation less than three years
     (other than U.S. Government securities), provided, however, that no more
     than 5% of the Fund's total assets are invested in securities issued by
     issuers which (including predecessors) have been in operation less than
     three years;
    
 
   
9.   invest more than 15% of the Fund's net assets (taken at the greater of cost
     or market value) in securities that are illiquid or not readily marketable
     excluding (a) Rule 144A securities that have been determined to be liquid
     by the Board of Trustees; and (b) commercial paper that is sold under
     Section 4(2) of the Securities Act which: (i) is not traded flat or in
     default as to interest or principal; and (ii) is rated in one of the two
     highest categories by at least two nationally recognized statistical rating
     organizations and the Fund's Board of Directors has determined the
     commercial paper to be liquid; or (iii) is rated in one of the two highest
     categories by one nationally recognized statistical rating agency and the
     Fund's Board of Directors has determined that the commercial paper is of
     equivalent quality and is liquid;
    
 
   
10.  (except for the Small Cap Fund, Large Cap Growth Fund and High Yield Bond
     Fund) invest in securities issued by an issuer any of whose officers,
     directors, trustees or security holders is an officer or Director of the
     Fund, or is an officer or director of the Adviser*, if after the purchase
     of the securities of such issuer for the Fund one or more of such persons
     own beneficially more than
    
 
                                     SAI-12
 

<PAGE>
<PAGE>

     1/2 of 1% of the shares or securities, or both, all taken at market value,
     of such issuer, and such persons owning more than 1/2 of 1% of such
     shares or securities together own beneficially more than 5% of such shares
     or securities, or both, all taken at market value;
 
   
11.  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 or (except for the Small Cap Fund, Large
     Cap Growth Fund and High Yield Bond Fund) if, as a result, more than 2% of
     the Fund's net assets would be invested in warrants not listed on a
     recognized United States or foreign stock exchange, to the extent permitted
     by applicable state securities laws;
    
 
12.  write puts and calls on securities unless each of the following conditions
     are met: (a) the security underlying the put or call is within the
     investment policies of the Fund and the option is issued by the Options
     Clearing Corporation, except for put and call options issued by non-U.S.
     entities or listed on non-U.S. securities or commodities exchanges; (b) the
     aggregate value of the obligations underlying the puts determined as of the
     date the options are sold shall not exceed 5% of the Fund's net assets; (c)
     the securities subject to the exercise of the call written by the Fund must
     be owned by the Fund at the time the call is sold and must continue to be
     owned by the Fund until the call has been exercised, has lapsed, or the
     Fund has purchased a closing call, and such purchase has been confirmed,
     thereby extinguishing the Fund's obligation to deliver securities pursuant
     to the call it has sold; and (d) at the time a put is written, the Fund
     establishes a segregated account with its custodian consisting of cash or
     short-term U.S. Government securities equal in value to the amount the Fund
     will be obligated to pay upon exercise of the put (this account must be
     maintained until the put is exercised, has expired, or the Fund has
     purchased a closing put, which is a put of the same series as the one
     previously written);
 
13.  buy and sell puts and calls on securities, stock index futures or options
     on stock index futures, or financial futures or options on financial
     futures unless: (a) the options or futures are offered through the
     facilities of a national securities association or are listed on a national
     securities or commodities exchange, except for put and call options issued
     by non-U.S. entities or listed on non-U.S. securities or commodities
     exchanges; (b) the aggregate premiums paid on all such options which are
     held at any time do not exceed 20% of the Fund's total net assets; (c) the
     aggregate margin deposits required on all such futures or options thereon
     held at any time do not exceed 5% of the Fund's total assets; and (d) such
     activities are permitted by Regulation 4.5 under the Commodity Exchange
     Act; and
 
   
14.  (except for the Small Cap Fund, Large Cap Growth Fund and High Yield Bond
     Fund) distribute securities that are not readily marketable to residents of
     the State of Arizona when effecting redemptions in kind.
    
 
     ALL FUNDS. There will be no violation of any investment restriction if that
restriction is complied with at the time the relevant action is taken
notwithstanding a later change in market value of an investment, in net or total
assets, in the securities rating of the investment or any other later change.
 
DIRECTORS AND TRUSTEES
 
DIRECTORS
 
   
     The Company's Board consists of three directors. The same persons who are
the Company's Directors are also the Trust's Trustees. The Company's Board is
responsible for the overall management of the Fund, including the general
supervision and review of its investment activities. The Company's Board, in
turn, elects the officers of the Company. Similarly, the Trustees, as such, are
responsible for the overall management of the Trust, including the general
supervision and review of its investment activities. The officers of the Company
hold similar positions with the Trust with substantially the same
responsibilities. The addresses and principal occupations of the Company's
Director's and officers and the Trust's Trustees and officers are listed below.
As of June 30, 1997, the Directors and officers of the Company owned of record,
as a group, less than 1% of the outstanding shares of the Company. None of the
Trustees or Directors or officers receives compensation from the Company or the
Trust exceeding $60,000 per fiscal

year. Every Director who is an 'Interested Person' (within the meaning of the
1940 Act) of the Company is also an 'Interested Person' of the Trust. Similarly,
every Director who is not an 'Interested Person' of the Company is not an
'Interested Person' of the Trust.

INVESTMENT ADVISER AND FUNDS SERVICES AGENT
 
     Pursuant to Investment Advisory Agreements between the Trust and Union Bank
of Switzerland, New York Branch, the Branch serves as the Portfolios' investment
adviser. Pursuant to a Sub-Advisory Agreement between the Branch and UBS
International Investment London Limited, UBSII serves as the
sub-adviser to the International Equity Portfolio. The Branch, which
operates out of offices located at 

                                     SAI-15

<PAGE>
<PAGE>

   
1345 Avenue of the Americas, New York, New York, is licensed by the
Superintendent of Banks of the State of New York under
the banking laws of the State of New York and is subject to state and federal
banking laws and regulations applicable to a foreign bank that operates a state
licensed branch in the United States. UBSII is a wholly-owned direct subsidiary
of UBS Asset Management London Limited, which is a direct subsidiary of UBS UK
Holding Limited, which is in turn a wholly-owned direct subsidiary of the Bank.
UBSII was organized under the laws of the United Kingdom on June 19, 1986. (The
Adviser and the Sub-Adviser are collectively referred to as the 'Advisers'.)
Subject to the supervision of the Trustees, the Adviser, and in the case of the
International Equity Portfolio, UBSII, makes the Portfolios' day-to-day
investment decisions, arranges for the execution of portfolio transactions and
generally manages each Portfolio's investments and provides certain
administrative services.
    
 
     The investment advisory services provided by the Advisers to the Portfolios
are not exclusive under the terms of the advisory agreements. The Advisers are
free to and do render similar investment advisory services to others. The
Advisers serve as investment advisers to personal investors and act as
fiduciaries for trusts, estates and employee benefit plans. Certain of the
assets of trusts and estates under management are invested in common trust funds
for which the Advisers serve as trustees. The accounts managed or advised by the
Advisers have varying investment objectives and the Advisers invest assets of
such accounts in investments substantially similar to, or the same as, those
which are expected to constitute the principal investments of the Portfolios.
Such accounts are supervised by officers and employees of the Advisers (or their
affiliates) who may also be acting in similar capacities for the Portfolios. See
'Portfolio Transactions'.
 
   
     The Bank has branches, agencies, representative offices and subsidiaries in
Switzerland and in more than 40 cities outside Switzerland, including, in the
United States, New York City, Houston, Los Angeles and San Francisco. In
addition to the receipt of deposits and the making of loans and advances, the
Bank, through its offices and subsidiaries (including UBSII and UBSAM) engages
in a wide range of banking and financial activities typical of the world's major
international banks, including fiduciary, investment advisory and custodial
services and foreign exchange in the United States, Swiss, Asian and
Euro-capital markets. The Bank is one of the world's leading asset managers and
has been active in New York City since 1946. At December 31, 1996, the Bank
(including its consolidated subsidiaries) had total assets of $326.7 billion and
equity capital and reserves of $17.1 billion.
    
 
   
     BOND AND HIGH YIELD BOND FUNDS. The Adviser's fixed income analysts have
extensive experience in selecting bonds and monitoring their performance. These
analysts review the creditworthiness of individual issuers as well as the broad
economic trends likely to affect the bond markets.
    
 
   
     U.S. EQUITY FUND. While many investment advisers evaluate companies
primarily on their earnings and their price/earnings ratio, the Adviser uses a
different investment approach. The Adviser believes that dividend yields, rather
than earnings, are the best indicators of future performance. Consequently, the
Adviser will select attractively priced stocks with high dividends. In addition,
the Adviser's analysts often meet with company managers, often contact a
company's suppliers, review the business operations and financial statements of
companies and try to 'get behind' the numbers to gain a true sense of a
company's value.
    
 
   
     SMALL CAP AND LARGE CAP GROWTH FUNDS. The Sub-Adviser's portfolio managers
have extensive experience in managing equity portfolios. Based on the investment
objective of the Fund, the Sub-Adviser analyzes equity securities of either
small capitalization growth companies or large capitalization growth companies
in order to identify above average growth opportunities for each respective
Fund. These opportunities may be characterized by the combination of security
valuations (e.g. price relative to earnings and/or cash flow) and above average
earnings growth expectations.
    
 
   
     INTERNATIONAL EQUITY AND INSTITUTIONAL INTERNATIONAL EQUITY FUNDS. The
Sub-Adviser's analysts have extensive experience in managing international
portfolios. These analysts track the performance of more than 1,600 companies
around the world, and pay particular attention to the energy, life sciences,
technology and financial industries.

     The Sub-Adviser is a registered investment adviser under the Investment
Advisers Act of 1940, as amended.

     The Prospectus for each of the Funds contains a description of fees payable
to the Adviser. For the period April 2, 1996 (commencement of operations)
through December 31, 1996, the Bond Portfolio, U.S. Equity Portfolio and
International Equity Portfolio paid investment advisory fees equal to $0, $0 and
$13,839, respectively. The High Yield Bond Portfolio, Small Cap Portfolio and
Large Cap Growth Portfolios had not commenced operations as of December 31,
1996.
    
 
   
     The Branch has voluntarily agreed to waive its fees and reimburse each Fund
and its corresponding Portfolio for their respective operating expenses to the
extent that the operating expenses (excluding extraordinary items) of the Bond
Fund, High Yield Bond Fund, U.S. Equity Fund, Institutional International Equity
Fund, International Equity Fund, Small Cap Fund and Large Cap Growth Fund
exceed, on an annual basis, 0.80%, 0.90%, 0.90%, 0.95%, 1.40%, 1.20% and 1.00%,
respectively, of such Fund's average daily net assets. The Branch may modify or
discontinue this expense limitation at any time in the future with 30 days'
prior notice to the affected Fund. See 'Expenses'. For the period April 2, 1996
(commencement of operations) through December 31, 1996, UBS reimbursed the Bond
Fund, U.S. Equity Fund and International Equity Fund for expenses totaling
$80,050, $93,511 and $52,899, respectively. The High Yield Bond Fund,
Institutional International Equity Fund, Small Cap Fund and Large Cap Growth
Fund had not commenced operations as of December 31, 1996.
    
 
   
     Pursuant to the Sub-Advisory Agreements, the Sub-Advisers, under the
supervision of the Trustees and the Adviser, make the day-to-day investment
decisions for the International Equity, Small Cap, Large Cap Growth and High
Yield Bond Portfolios. Under the Sub-Advisory Agreement, the Adviser has agreed
to pay UBSII a fee, calculated daily and payable monthly equal, on an annual
basis, to 0.75% of the International Equity Portfolio's first $20 million of
average net assets, 0.50% of the next $30 million of average net assets, and
0.40% of average net assets in excess of $50 million. The Adviser is solely
responsible for paying this fee to UBSII. For the period April 2, 1996
(commencement of operations) through December 31, 1996, the Adviser paid
$154,659 to the UBSII on behalf of the International Equity Portfolio.
    
 
   
     Under the Sub-Advisory Agreements with UBSAM NY, the Adviser has agreed to
pay UBSAM NY a fee, calculated daily and payable monthly equal, on an annual
basis, to the following percentages of each Portfolio's respective average net
assets:

     The Adviser is solely responsible for paying this fee to UBSAM NY. The High
Yield Bond, Small Cap and Large Cap Growth Portfolios had not yet commenced
operations as of December 31, 1996.
    
 
   
     The Investment Advisory and Sub-Advisory Agreements will each continue in
effect until February 1998, and thereafter will be subject to annual approval by
the Trustees or the vote of a majority of the outstanding voting securities (as
defined in the 1940 Act) of each Portfolio, provided that in either case the
continuance also is approved by a majority of the Trustees who are not
interested persons (as defined in the 1940 Act) of the Trust by vote cast in
person at a meeting called for the purpose of voting on such approval. The
Investment Advisory and Sub-Advisory Agreements will terminate automatically if
assigned and are terminable at any time without penalty by a vote of a majority
of the Trustees or by a vote of the holders of a majority (as defined in the
1940 Act) of the Portfolio's outstanding shares on 60 days' written notice to
the Adviser or Sub-Adviser as applicable. Whenever a Fund, as a shareholder of a
Portfolio, is required by the 1940 Act to vote its Portfolio interest, the
Company will hold a meeting of that Fund's shareholders and will vote its
Portfolio interests proportionately as instructed by that Fund's shareholders.
See 'Organization'. Each Investment Advisory and Sub-Advisory Agreement is also
    
 
                                     SAI-17
 
<PAGE>

<PAGE>

   
terminable by the Adviser or Sub-Adviser, as applicable, on 60 days' written
notice to the Trust. See 'Additional Information'.
    
 
   
     In addition to the above noted investment advisory services, the Adviser
(but not the Sub-Advisers) also provides certain administrative services to the
Funds and the Portfolios and, subject to the supervision of the Board of
Trustees, as applicable, is responsible for: establishing performance standards
for the Funds' and Portfolios' third-party service providers and overseeing and
evaluating the performance of such entities; providing and presenting quarterly
management reports to the Directors and the Trustees; supervising the
preparation of reports for Fund and Portfolio shareholders; and establishing
voluntary expense limitations for the Fund and providing any resultant expense
reimbursement to the Fund.
    
 
     These administrative services are provided to the Portfolios by the Adviser
pursuant to the above discussed Investment Advisory Agreements. However, these
administrative services are provided to the Funds pursuant to a Funds Services
Agreement between the Adviser and the Company. The Adviser is not entitled to a
fee from the Company or the Funds under the terms of the Funds Services
Agreement.
 
     The Glass-Steagall Act and other applicable laws generally prohibit banks,
such as Union Bank of Switzerland, from engaging in the business of underwriting
or distributing securities, and the Board of Governors of the Federal Reserve
System has issued an interpretation to the effect that under these laws a bank
holding company registered under the federal Bank Holding Company Act or certain
subsidiaries thereof may not sponsor, organize, or control a registered open-end
investment company continuously engaged in the issuance of its shares, such as
the Company. The interpretation does not prohibit a holding company or a
subsidiary thereof from acting as investment adviser or custodian to such an
investment company. The Advisers believe that they may perform the services for
the Portfolios and the Funds contemplated by the Investment Advisory,
Sub-Advisory and Funds Services Agreements without violating the Glass-Steagall
Act or other applicable banking laws or regulations. State laws on this issue
may differ from the interpretation of relevant federal law, and banks and
financial institutions may be required to register as dealers pursuant to state
securities laws. However, it is possible that future changes in either federal
or state statutes and regulations concerning the permissible activities of banks
or trust companies, as well as further judicial or administrative decisions and
interpretations of present and future statutes and regulations, might prevent
these entities from continuing to perform such services.
 
   
     If the Adviser or Sub-Advisers were prohibited from providing these
services to the Funds or the Portfolios, it is expected that the Directors and
Trustees, as applicable, would recommend to shareholders that they approve new
agreements with other qualified service providers.
    
 
   
     ADMINISTRATORS. The Trust and the Company employ Investors Fund Services
(Ireland) Limited ('IBT Ireland'), a subsidiary of Investors Bank & Trust
Company ('Investors Bank') and Investors Bank, respectively, as Administrators
under Administration Agreements (the 'Administration Agreements') to provide
certain administrative services. The services provided by IBT Ireland and
Investors Bank under the Administration Agreements include certain accounting,
clerical and bookkeeping services, Blue Sky (for the Funds only), corporate
secretarial services and assistance in the preparation and filing of tax returns
and reports to shareholders and the SEC. Investors Bank is a wholly-owned
subsidiary of Investors Financial Services Corp., a publicly-held corporation
and holding company registered under the Bank Holding Company Act of 1956. For
its services under the Administration Agreement, each Fund pays Investors Bank a
fee which is calculated daily and paid monthly, equal, on an annual basis, to
0.065% of the Fund's first $100 million in average daily net assets and 0.025%
of the next $100 million in average daily net assets. Investors Bank does not
receive a fee from the Fund on average daily net assets in excess of $200
million. For its services under the Administration Agreement, the Portfolio pays
IBT Ireland a fee which is calculated daily and paid monthly equal, on an annual
basis, to 0.07% of the Portfolio's first $100 million in average daily net
assets and 0.05% of the assets in excess of $100 million. IBT Ireland's
principal offices are located at Deloitte & Touche House, 29 Earlsfort Terrace,
Dublin 2, Ireland. Investors Bank's principal offices are located at 200
Clarendon Street, Boston, Massachusetts 02116.

while the Bond Fund, U.S. Equity Fund and International Equity Fund paid

     The Administration Agreements may be renewed or amended by the Directors or
Trustees, as applicable, without shareholder vote. The Administration Agreements
are terminable at any time without penalty by a vote of a majority of the
Directors or Trustees, as applicable, on not less than 60 days' written notice
to the other party. The Administrators may subcontract for the performance of
their obligations under the Administration Agreements with the prior written
consent of the Directors or Trustees, as applicable. If an Administrator
subcontracts all or a portion of its duties to another party, that Administrator
shall be fully responsible for the acts and omissions of any such
subcontractor(s) as it would be for its own acts or omissions.
    
 
DISTRIBUTOR
 
   
     DISTRIBUTOR. Pursuant to a Distribution Agreement, First Fund Distributors,

     Investors Bank (the 'Custodian'), whose principal offices are located at
200 Clarendon Street, Boston, Massachusetts 02116, serves as the custodian and
transfer and dividend disbursing agent for the Funds and the Portfolios.
Pursuant to the Custodian Agreements with the Trust, on behalf of each
Portfolio, and the Company, on behalf of each Fund, the Custodian is responsible
for maintaining the books and records of portfolio transactions and holding
portfolio securities and cash. As transfer agent and dividend disbursing agent,
the Custodian is responsible for maintaining account records detailing the
ownership of Portfolio and Fund interests and for crediting income, capital
gains and other changes in share ownership to investors' accounts. The Custodian
will perform its duties as the Portfolios' transfer agent and dividend
disbursing agent from its offices located at 1 First Canadian Place, Suite 2800,

SHAREHOLDER SERVICES
    

   
     The Company (excluding UBS Institutional International Equity Fund) has

federal or state-chartered bank, trust company, savings and loan association or
savings bank, or broker-dealer. Pursuant to each shareholder servicing
agreement, an Eligible Institution, as agent for its customers who are
purchasing shares of the Fund, will perform shareholder services for these
investors, which include performing shareholder account administrative and
servicing functions, such as answering inquiries regarding account status and
history, the manner in which purchases and redemptions of shares
may be made and certain other matters pertaining to each Fund, assisting
customers in designating and changing dividend options, account designations and
addresses, providing necessary personnel and facilities to coordinate the
establishment and maintenance of shareholder accounts and records with the
Funds' Distributor and transfer agent, assisting investors seeking to purchase
or redeem Fund shares,

arranging for the wiring or other transfer of funds to and from
customer accounts in connection with orders to purchase or redeem Fund
shares, verifying purchase and redemption orders, transfers among and changes in
accounts and providing other related services. In return for these services,
each Fund has agreed to pay each Eligible Institution a fee equal on an annual
basis to 0.25% of the average daily net assets of such Fund represented by
shares of the Fund owned during the period for which payment is being made by
customers of the Eligible Institution. For the period April 2, 1996
(commencement of operations) through December 31, 1996, the shareholder service
fee for the Bond Fund, U.S. Equity Fund and International Equity Fund amounted
to $7,632, $12,965 and $20,658, respectively, all of which were waived.
    
 
   
     As discussed under 'Investment Adviser and Shareholder Servicing Agent',
the Glass-Steagall Act and other applicable laws and regulations limit the
activities of bank holding companies and certain of their subsidiaries in
connection with registered open-end investment companies. The activities of the
Branch under the Shareholder Servicing Agreement, the Investment Advisory
Agreement and the Funds Services Agreement and UBSII and UBSAM under the
Sub-Advisory Agreements, may raise issues under these laws. However, the Branch,
UBSII and UBSAM believe that they may properly perform these services and the
other activities described herein and in the Prospectuses without violating the
Glass-Steagall Act or other applicable banking laws or regulations.
    
 
   
     If the Branch, UBSII or UBSAM were prohibited from providing their
respective services under the above noted agreements, the Directors and
Trustees, as applicable, would seek an alternative provider of such services. In
such an event, changes in the operation of the Funds or the Portfolios might
occur and shareholders might not receive the same level of service previously
provided by the Branch, UBSII and UBSAM.
    
 
   
INDEPENDENT ACCOUNTANTS
    
 
   
     The Company's and the Trust's independent accounting firm is Price
Waterhouse LLP, 1177 Avenue of the Americas, New York, New York 10036. The U.S.
firm of Price Waterhouse is a Registered Limited Liability Partnership (LLP)
under the laws of the State of Delaware. Price Waterhouse LLP will conduct an
annual audit of the financial statements of each Fund and Portfolio, assist in
the review and filing of the federal and state income tax returns of the Funds
and Portfolios and consult with the Funds and Portfolios as to matters of
accounting and federal and state income taxation.
    
 
EXPENSES
 
     Each Fund and Portfolio is responsible for the fees and expenses
attributable to it. Each Fund will bear its proportionate share of the expenses
in its corresponding Portfolio.
 
   
     The Branch has voluntarily agreed to limit the total operating expenses of
each Fund (including each Fund's proportionate share of the expenses incurred by
its corresponding Portfolio), excluding ordinary expenses, as set forth in each
Fund's Prospectus under the caption 'Expenses'. The Branch may modify or
discontinue this fee waiver and expense limitation at any time in the future
with 30 days' prior notice to the affected Fund. For additional information
regarding waivers or expense subsidies, see 'Management' in the Prospectus.
    
 
PURCHASE OF SHARES
 
     Investors may purchase Fund shares as described in each Prospectus under
'Purchase of Shares.' Fund shares are sold on a continuous basis without a sales
charge at the net asset value per share next determined after receipt of a
purchase order.
 
   
     For each Fund except the Institutional International Equity Fund, the
minimum investment requirement for certain retirement plans such as Individual
Retirement Accounts ('IRAs'), Self-Employed Retirement Plans ('SERPs'), 401(k)
Plans and other tax-deferred plans is $2,000. The minimum investment requirement
    

                                     SAI-20
 

<PAGE>
<PAGE>

   
for all subsequent investments is $500. The minimum investment requirement for
accounts established for the benefit of minors under the 'Uniform Gift to
Minor's Act' is $5,000. The minimum investment requirement for all subsequent
investments is $1,000. The minimum investment requirement for employees of the
Bank and its affiliates is $5,000. The minimum subsequent investment is $1,000.
These minimum investment requirements may be waived at the Fund's discretion.
The Institutional International Equity Fund has not adopted special minimum
investment requirements for retirement plans.
    
 
     In addition, the minimum investment requirements may be met by aggregating
the investments of related shareholders. A 'related shareholder' is limited to
an immediate family member, including mother, father, spouse, child, brother,
sister and grandparent and includes step and adoptive relationships.
 
     Each Fund may, at its own option, accept securities in payment for shares.
The securities tendered are valued by the methods described in 'Net Asset Value'
as of the day the Fund shares are purchased. This is a taxable transaction to
the investor. Securities may be accepted in payment for shares only if they are,
in the judgment of the Advisers, appropriate investments for the Portfolio
corresponding to that Fund. In addition, securities accepted in payment for
shares must: (i) meet the investment objective and policies of the relevant
Portfolio; (ii) be acquired by the Fund for investment and not for resale (other
than for resale to the corresponding Portfolio); (iii) be liquid securities that
are not restricted as to transfer either by law or by market liquidity; and (iv)
have a value that is readily ascertainable, as evidenced by a listing on a stock
exchange, over-the-counter market or by readily available market quotations from
a dealer in such securities. Each Fund reserves the right to accept or reject at
its own option any and all securities offered in payment for its shares.
 
REDEMPTION OF SHARES
 
     Investors may redeem shares of each Fund as described in the Prospectus
under 'Redemption of Shares'.
 
     If the Directors and Trustees determine that it would be detrimental to the
best interest of the remaining shareholders of a Fund or Portfolio to effect
redemptions wholly or partly in cash, payment of the redemption price may be
made in whole or in part by an in-kind distribution of securities from the
Portfolio, in lieu of cash, in conformity with the applicable rules of the SEC.
If shares are redeemed in-kind, the redeeming shareholder might incur
transaction costs in converting the securities into cash. The methods of valuing
portfolio securities distributed to a shareholder are described under 'Net Asset
Value', and such valuations will be made as of the same time the redemption
price is determined.
 
     FURTHER REDEMPTION INFORMATION. The right of redemption may be suspended or
the date of payment postponed, in the case of the Company and the Trust: (i)
during periods when the New York Stock Exchange (the 'NYSE') is closed for other
than weekends and holidays or when trading on the NYSE is suspended or
restricted; (ii) during periods in which an emergency exists, as determined by
the SEC, which causes disposal by a Portfolio of, or evaluation of the net asset
value of, its securities to be unreasonable or impracticable; or (iii) for such
other periods as the 1940 Act or the SEC may permit.
 
EXCHANGE OF SHARES
 
   
     An investor may exchange Fund shares for shares of any other series of the
Company as described under 'Exchange of Shares' in the Prospectuses. Investors
considering an exchange of Fund shares for shares of another Company series
should read the prospectus of the series into which the transfer is being made
prior to such exchange (see the section regarding purchase of shares in the
appropriate Prospectus). Requests for exchange are made in the same manner as
requests for redemptions (see the section regarding redemption of shares in the
appropriate Prospectus). Shares of the acquired series are purchased for
settlement when the proceeds from redemption become available. The Company
reserves the right to discontinue, alter or limit this exchange privilege
at any time. Shares of the Institutional International Equity Fund
are not eligible for the exchange privilege.

DIVIDENDS AND DISTRIBUTIONS
 
     Each Fund will declare and pay dividends and distributions as described
under 'Dividends and Distributions' in its Prospectus.
 
     Determination of the net income for the Bond Fund is made at the times
described in that Prospectus; in addition, net investment income for days other
than business days is determined at the time net asset value is determined on
the prior business day.
 
NET ASSET VALUE
 
     Each Fund computes its net asset value once daily at the close of business
on Monday through Friday as described under 'Net Asset Value' in the Prospectus.
The net asset value will not be computed on a day in which no orders to purchase
or redeem Fund shares have been received or on any day on which the NYSE is
closed, including the following legal holidays: New Year's Day, Presidents' Day,
Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and
Christmas Day. On days when U.S. trading markets close early in observance of
these holidays, the Funds and the Portfolios would expect to close for purchases
and redemptions at the same time. The days on which net asset value is
determined are the Funds' business days.
 
     The net asset value per share of each Fund equals the value of that Fund's
pro rata interest in its corresponding Portfolio plus the value of all its other
assets not invested in the Portfolio, if any, less its total liabilities,
divided by the number of outstanding shares of that Fund. The following is a
discussion of the procedures used by the Portfolios in valuing their assets.
 
   
     In the case of the Bond and High Yield Bond Portfolios, securities with a
maturity of 60 days or more, including securities that are listed on an exchange
or traded over-the-counter, are valued by the Portfolios by using bid quotes
from at least one dealer or, in all other cases, by taking into account various
factors affecting market value, including yields and prices of comparable
securities, indications as to values from dealers and general market conditions.
All portfolio securities with a remaining maturity of less than 60 days are
valued by the amortized cost method, whereby such securities are valued at
acquisition cost as adjusted for amortization of premium or accretion of
discount to maturity. Because many of the municipal bond issues outstanding do
not have large principal obligations and because of the varying risk factors
applicable to each issuer, no readily available market quotations exist for most
municipal securities.
    
 
   
     In the case of the U.S. Equity, Small Cap, Large Cap Growth and
International Equity Portfolios, securities listed on domestic exchanges, other
than options on stock indices, are valued using the last sales price on the most
representative exchange at 4:00 p.m. New York time or, in the absence of
recorded sales, at the average of readily available closing bid and asked prices
on such exchange or, in the absence of such prices, at the readily available
closing bid price on such exchange. Securities listed on foreign exchanges are
valued at the last quoted sale price available before the time when net assets
are valued or, in the absence of such recorded sales, at the average of readily
available closing bid and asked prices on such exchange or, in the absence of
such prices, at the readily available closing bid price on such exchange.
Unlisted securities are valued at the average of the quoted bid and asked prices
in the over-the-counter market. The value of each security for which readily
available market quotations exist is based on a decision as to the broadest and
most representative market for such security. For purposes of calculating net
asset value per share, all assets and liabilities initially expressed in foreign
currencies will be converted into U.S. dollars at the prevailing market rates
available at the time of valuation.
    
 
     Options on stock indices traded on national securities exchanges are valued
at the close of options trading on such exchanges, which is currently 4:10 p.m.,
New York time. Stock index futures and related options traded on commodities
exchanges are valued at their last sales price as of the close of such
commodities exchanges, which is currently 4:15 p.m., New York time. Securities
or other assets for which market quotations are not readily available are
valued at fair value in accordance with procedures established by and under the
general supervision of the Trustees. Such procedures include the use of
independent pricing services, indications as to values from dealers and general
market conditions. Short-

term investments that mature in 60 days or less are valued at amortized cost
method (as discussed above) if their original maturity was 60 days or less, or
by amortizing their value on the 61st day prior to maturity, if their original
maturity when acquired by a Portfolio was more than 60 days, unless this is
determined not to represent fair value by the Trustees.
 
     Trading in securities on most foreign exchanges and over-the-counter
markets is normally completed before the close of the NYSE and may also take
place on days on which the NYSE is closed. If events materially affecting the
value of securities occur between the time when the exchange on which they are
traded closes and the time when a Portfolio's net asset value is calculated,
such securities may be valued at fair value in accordance with procedures
established by and under the general supervision of the Trustees.
 
     If market quotations for the securities of any Portfolio are not readily
available, such securities will be valued at 'fair value' as determined in good
faith by the Trustees.
 
PERFORMANCE DATA
 
     From time to time, the Funds may quote performance in terms of yield,
actual distributions, total return or capital appreciation in reports, sales
literature and advertisements published by the Funds. Current performance
information for the Funds may be obtained by calling your Eligible Institution.
See 'Additional Information' in the Prospectus.
 
   
     YIELD QUOTATIONS. As required by regulations of the SEC, the annualized
yield for the Bond Fund and the High Yield Bond Fund is computed by dividing the
Funds' net investment income per share (which may differ from the net income per
share used for accounting purposes) earned during a 30-day period by its net
asset value on the last day of the period. The average daily number of Fund
shares outstanding during the period that are eligible to receive dividends is
used in determining the net investment income per share. Income is computed by
totaling the interest earned on all debt obligations during the period and
subtracting from that amount the total of all recurring expenses incurred during
the period. The 30-day yield is then annualized on a bond-equivalent basis
assuming semi-annual reinvestment and compounding of net investment income, as
described under 'Additional Information' in the Prospectus.
    
 
   
     TOTAL RETURN QUOTATIONS. As required by SEC regulations, the average annual
total return of the Bond, High Yield Bond, U.S. Equity, Small Cap, Large Cap
Growth, International Equity and Institutional International Equity Funds for a
period is computed by assuming a hypothetical initial investment of $1,000. It
is then assumed that all of the dividends and distributions by that Fund over
the relevant period are reinvested. It is then assumed that at the end of the
period the entire amount is redeemed. The average annual total return is then
calculated by determining the annual rate required for the initial investment to
grow to the amount which would have been received upon redemption (i.e., the
average annual compound rate of return).
    
 
     Aggregate total returns, reflecting the cumulative percentage change over a
measuring period, may also be calculated.
 
     GENERAL. A Fund's performance will vary from time-to-time depending upon
market conditions, the composition of its corresponding Portfolio and its
operating expenses. Consequently, any given performance quotation should not be
considered representative of a Fund's performance for the future. In addition,
because performance will fluctuate, it may not provide a basis for comparing an
investment in a Fund with certain bank deposits or other investments that pay a
fixed yield or return for a stated period of time.
 
     Comparative performance information may be used from time to time in
advertising the Funds' shares, including data from Lipper Analytical Services,
Inc., Lehman Government/Corporate Intermediate Bond Index, Micropal, Inc.,
Ibbotson Associates, Morningstar Inc., the S&P 500 Composite Stock Price
Index, the Dow Jones Industrial Average, the Frank Russell Indices, The EAFE'r'
Index and other industry publications.

PORTFOLIO TRANSACTIONS
 
     The Advisers place orders for all purchases and sales of securities on
behalf of the Portfolios. The Advisers enter into repurchase agreements and
reverse repurchase agreements and effect loans of portfolio securities on behalf
of the Portfolios. See 'Investment Objectives and Policies'.
 
     Fixed income and debt securities and municipal bonds and notes are
generally traded at a net price with dealers acting as principal for their own
accounts without a stated commission. The price of the security usually includes
profit to the dealers. In underwritten offerings, securities are purchased at a
fixed price that includes an amount of compensation to the underwriter,
generally referred to as the underwriter's concession or discount. Occasionally,
certain securities may be purchased directly from an issuer, in which case no
commissions or discounts are paid.
 
   
     Portfolio transactions for the Bond and High Yield Bond Portfolios will be
undertaken principally to accomplish their objectives in relation to expected
movements in the general level of interest rates. The Bond and High Yield Bond
Portfolios may engage in short-term trading consistent with their objectives.
    
 
   
     In connection with portfolio transactions for the Bond and High Yield Bond
Portfolios, the Adviser intends to seek best price and execution on a
competitive basis for both purchases and sales of securities. Portfolio turnover
may vary from year to year, as well as within a year. The annual portfolio
turnover rate for the Bond and High Yield Bond Portfolios is expected to be
under 100%. For the period April 2, 1996 (commencement of operations) through
December 31, 1996, the portfolio turnover rate for the Bond Portfolio was 100%.
The High Yield Bond Portfolio had not commenced operations as of December 31,
1996.
    
 
   
     In connection with portfolio transactions for the U.S. Equity, Small Cap,
Large Cap Growth and International Equity Portfolios, the overriding objective
is to obtain the best possible execution of purchase and sale orders. Portfolio
turnover may vary from year to year, as well as within a year. The annual
portfolio turnover rate for the U.S. Equity Small Cap, Large Cap Growth and
International Equity Portfolios is expected to be under 100%. For the period
April 2, 1996 (commencement of operations) through December 31, 1996, the
portfolio turnover rate for the U.S. Equity Portfolio and International Equity
Portfolio was 19% and 42%, respectively. The Small Cap, Large Cap Growth and
Institutional International Equity Portfolios had not commenced operations as of
December 31, 1996.
    
 
   
     In selecting a broker, the Adviser or Sub-Advisers, as applicable, consider
a number of factors including: the price per unit of the security; the broker's
reliability for prompt, accurate confirmations and on-time delivery of
securities; the broker's financial condition; and the commissions charged. A
broker may be paid a brokerage commission greater than that another broker might
have charged for effecting the same transaction if, after considering the
foregoing factors, the Adviser or Sub-Advisers decide that the broker chosen
will provide the best possible execution. The Advisers monitor the
reasonableness of the brokerage commissions paid in light of the execution
received. The Trustees regularly review the reasonableness of commissions and
other transaction costs incurred by the Portfolios in light of the facts and
circumstances deemed relevant, and, in that connection, will review reports and
published data concerning transaction costs incurred by institutional investors
generally. Research services provided by brokers to which the Advisers have
allocated brokerage business in the past include economic statistics and
forecasting services, industry and company analyses, portfolio strategy
services, quantitative data, and consulting services from economists and
political analysts. Research services furnished by brokers are used for the
benefit of all the Adviser's clients and not solely or necessarily for the
benefit of the Portfolios. The Advisers believe that the value of research
services received is not determinable and does not significantly increase
expenses. The Portfolios do not reduce their fee to the Adviser by any amount
that might be attributable to the value of such services. For the period April
2, 1996 (commencement of operations) through December 31, 1996, the Trust paid
brokerage commissions on behalf of U.S. Equity Portfolio and International
Equity Portfolio of $32,099, and $139,846, respectively.
The Small Cap, Large Cap Growth and Institutional International Equity
Portfolios had not commenced operations as of December 31, 1996.

    
   
 
     Subject to the overriding objective of obtaining the best possible
execution of orders, the Advisers may allocate a portion of a Portfolio's
brokerage transactions to their affiliates. In order for their affiliates
    
 
                                     SAI-24
 

<PAGE>
<PAGE>

   
to effect any portfolio transactions for the Portfolios, the commissions, fees
or other remuneration received by such affiliates must be reasonable and fair
compared to the commissions, fees, or other remuneration paid to other brokers
in connection with comparable transactions involving similar securities being
purchased or sold on a securities exchange during a comparable period of time.
Furthermore, the Trustees, including a majority of the Trustees who are not
'interested persons', have adopted procedures that are reasonably designed to
ensure that any commissions, fees, or other remuneration paid to such affiliates
are consistent with the foregoing standard.
    
 
   
     Portfolio securities will not be purchased from or through or sold to or
through the Portfolio's Adviser, Sub-Advisers, Distributor or any 'affiliated
person' (as defined in the 1940 Act) or any affiliated person of such a person
when such entities are acting as principals, except to the extent permitted by
law. In addition, the Portfolios will not purchase securities during the
existence of any underwriting group relating thereto of which the Adviser,
Sub-Advisers or affiliate thereof is a member, except to the extent permitted by
law.
    
   
 
     On those occasions when the Advisers deem the purchase or sale of a
security to be in the best interests of a Portfolio as well as other customers
including other Portfolios, the Advisers to the extent permitted by applicable
laws and regulations may, but are not obligated to, aggregate the securities to
be sold or purchased for a Portfolio with those to be sold or purchased for
other customers in order to obtain best execution, including lower brokerage
commissions if appropriate. In such an event, the securities so purchased or
sold as well as any expenses incurred in the transaction will be allocated by
the Advisers in a manner that is equitable and consistent with their fiduciary
obligations to their clients. In some instances, this procedure might adversely
affect a Portfolio.
    
   
 
     If a Portfolio writes an option and effects a closing purchase transaction
with respect to an option written by it, such transaction will normally be
executed by the same broker-dealer who executed the sale of the option. The
writing of options by a Portfolio will be subject to limitations established by
each of the exchanges governing the maximum number of options in each class that
may be written by a single investor or group of investors acting in concert,
regardless of whether the options are written on the same or different exchanges
or are held or written in one or more accounts or through one or more brokers.
The number of options that a Portfolio may write may be affected by options
written by the Advisers for other investment advisory clients. An exchange may
order the liquidation of positions found to be in excess of these limits and it
may impose certain other sanctions.
    

   
ORGANIZATION
    
   
UBS PRIVATE INVESTOR FUNDS, INC.
    
 
   
     UBS Private Investor Funds, Inc. is a Maryland corporation and is currently
authorized to issue shares of common stock, par value $0.001 per share, in eight
series: The UBS Bond Fund Series; The UBS Tax Exempt Bond Fund Series; The UBS
U.S. Equity Fund Series; The UBS Institutional International Equity Fund Series;
The UBS International Equity Fund Series; The UBS High Yield Bond Fund Series;
The UBS Small Cap Fund Series; and The UBS Large Cap Growth Fund Series.
    
 
   
     Each share of a series issued by the Company will have a pro rata interest
in the assets of that series. The Company is currently authorized to issue
500,000,000 shares of common stock, including 10,000,000 shares of each of the
eight current series. Under Maryland law, the Board has the authority to
increase the number of shares of stock that the Company has the authority to
issue. Each share has one vote (and fractional shares have a corresponding
fractional vote) with respect to matters upon which shareholder vote is
required; stockholders have no cumulative voting rights with respect to their
shares. Shares of all series vote together as a single class except that if the
matter being voted upon affects only a particular series then it will be voted
on only by that series. If a matter affects a particular series
differently from other series, that series will vote separately on such
matter. Each share is entitled to participate equally in dividends and
distributions declared by the Directors with respect to the relevant series, and
in the net distributable assets of such series on liquidation.

     Under Maryland law, the Company is not required to hold an annual meeting
of stockholders unless required to do so under the 1940 Act. It is the Company's
policy not to hold an annual meeting of stockholders unless so required. All
shares of the Company (regardless of series) have noncumulative voting rights
for the election of Directors. Under Maryland law, the Company's Directors may
be removed by vote of stockholders. The Board currently consists of three
directors.
    
 
   
UBS INVESTOR PORTFOLIOS TRUST
    
 
   
     UBS Investor Portfolios Trust, a master trust fund formed under New York
law, was organized on February 9, 1996. The Declaration of Trust permits the
Trustees to issue interests in one or more subtrusts or series. To date, six
series have been authorized. Each series (i.e., a Portfolio) of the Trust
corresponds to a Fund of the Company, with the exception that the International
Equity Portfolio corresponds to the International Equity Fund and the
Institutional International Equity Fund.
    
 
   
     A copy of the Trust's Declaration of Trust is on file in the office of its
Administrator.
    
 
     Holders of interest in the Trust, such as the Funds, may redeem all or any
part of their interest in the Trust at any time, upon the submission of a
redemption request in proper form. See 'Redemption of Shares'.
 
TAXES
 
     Each Fund has qualified and intends to remain qualified as a regulated
investment company (a 'RIC') under Subchapter M of the Code. As a RIC, a Fund
must, among other things: (a) derive at least 90% of its gross income from
dividends, interest, payments with respect to loans of stock and securities,
gains from the sale or other disposition of stock, securities or foreign
currency and other income (including but not limited to gains from options,
futures, and forward contracts) derived with respect to its business of
investing in such stock, securities or foreign currency; (b) derive less than
30% of its gross income from the sale or other disposition of stock, securities,
options, futures or forward contracts (other than options, futures or forward
contracts on foreign currencies) held less than three months; and (c) diversify
its holdings so that, at the end of each fiscal quarter, (i) at least 50% of the
value of the Fund's total assets is represented by cash, U.S. Government
securities, investments in other RICs and other securities limited in respect of
any one issuer, to an amount not greater than 5% of the Fund's total assets, and
10% of the outstanding voting securities of such issuer and (ii) not more than
25% of the value of its total assets is invested in the securities of any one
issuer (other than U.S. Government securities or the securities of other RICs).
As a RIC, a Fund (as opposed to its shareholders) will not be subject to federal
income taxes on the net investment income and capital gains that it distributes
to its shareholders, provided that at least 90% of its net investment income and
realized net short-term capital gains in excess of net long-term capital losses
for the taxable year is distributed.
 
     For federal income tax purposes, dividends that are declared by a Fund in
October, November or December as of a record date in such month and actually
paid in January of the following year will be treated as if they were paid on
December 31 of the year declared. Therefore, such dividends will generally be
taxable to a shareholder in the year declared rather than the year paid.
 
     Gains or losses on sales of securities by a Portfolio will be treated as
long-term capital gains or losses if the securities have been held by it for
more than one year except in certain cases where, if applicable, a Portfolio
acquires a put or writes a call thereon. Other gains or losses on the sale of
securities will be short-term capital gains or losses. Gains and losses on the
sale, lapse or other termination of options on securities will be treated as
gains and losses from the sale of securities. If an option written by a
Portfolio lapses or is terminated through a closing transaction, such as a
repurchase by the Portfolio of the option from its holder, the Portfolio will
realize a short-term capital gain or loss, depending on whether the premium
income is greater or less than the amount paid by the Portfolio in the closing
transaction. If securities are purchased by a Portfolio pursuant to the
exercise of a put option written by it, the Portfolio will subtract the premium
received from its cost basis in the securities purchased.

     Under the Code, gains or losses attributable to disposition of foreign
currency or to foreign currency contracts, or to fluctuations in exchange rates
between the time a Portfolio accrues income or receivables or expenses or other
liabilities denominated in a foreign currency and the time a Portfolio actually
collects such income or pays such liabilities, are treated as ordinary income or
ordinary loss. Similarly, gains or losses on the disposition of debt securities
held by a Portfolio, if any, denominated in foreign currency, to the extent
attributable to fluctuations in exchange rates between the acquisition and
disposition dates are also treated as ordinary income or loss.
 
     Forward currency contracts, options and futures contracts entered into by a
Portfolio may create 'straddles' for U.S. federal income tax purposes and this
may affect the character and timing of gains or losses realized by a Portfolio
on forward currency contracts, options and futures contracts or on the
underlying securities. 'Straddles' may also result in the loss of the holding
period of underlying securities for purposes of the 30% of gross income test
described above, and therefore, a Portfolio's ability to enter into forward
currency contracts, options and futures contracts may be limited.
 
     Certain options, futures and foreign currency contracts held by a Portfolio
at the end of each fiscal year will be required to be 'marked to market' for
federal income tax purposes -- i.e., treated as having been sold at market
value. For such options and futures contracts, 60% of any gain or loss
recognized on these deemed sales and on actual dispositions will be treated as
long-term capital gain or loss, and the remainder will be treated as short-term
capital gain or loss regardless of how long the Portfolio has held such options
or futures. Any gain or loss recognized on foreign currency contracts will be
treated as ordinary income.
 
     FOREIGN SHAREHOLDERS. Distributions of net investment income and realized
net short-term capital gains in excess of net long-term capital losses to a
shareholder who, as to the United States, is a non-resident alien individual,
fiduciary of a foreign trust or estate, foreign corporation or foreign
partnership (a 'foreign shareholder') will be subject to U.S. withholding tax at
the rate of 30% (or lower treaty rate) unless the dividends are effectively
connected with a U.S. trade or business of the shareholder, in which case the
dividends will be subject to tax on a net income basis at the graduated rates
applicable to U.S. individuals or domestic corporations. Distributions of net
long-term capital gains to foreign shareholders will not be subject to U.S. tax
unless the distributions are effectively connected with the shareholder's trade
or business in the United States or, in the case of a shareholder who is a
non-resident alien individual, the shareholder was present in the United States
for more than 182 days during the taxable year and certain other conditions are
met.
 
     In the case of a foreign shareholder who is a nonresident alien individual
and who is not otherwise subject to withholding as described above, a Fund may
be required to withhold U.S. federal income tax at the rate of 31% unless IRS
Form W-8 is provided. See 'Taxes' in the Prospectus. Transfers by gift of shares
of a Fund by a foreign shareholder who is a nonresident alien individual will
not be subject to U.S. federal gift tax, but the value of shares of the Fund
held by such a shareholder at his or her death will be includible in his or her
gross estate for U.S. federal estate tax purposes.
 
     FOREIGN TAXES. It is expected that the International Equity Portfolio may
be subject to foreign withholding taxes with respect to income received from
sources within foreign countries. In the case of the International Equity
Portfolio, so long as more than 50% in value of the Portfolio's total assets at
the close of any taxable year consists of stock or securities of foreign
corporations, the Portfolio may elect to treat any foreign income taxes paid by
it as paid directly by its shareholders. The Portfolio will make such an
election only if it deems it to be in the best interest of its shareholders. The
Portfolio will notify its shareholders in writing each year if they make the
election and of the amount of foreign income taxes, if any, to be treated as
paid by the shareholders. If the Portfolio makes the election, each shareholder
of the International Equity Fund will be required to include in his or her
income their proportionate share of the amount of foreign income taxes paid by
the Portfolio and will be entitled to claim either a credit (subject to the
limitations discussed below), or, if he or she itemizes deductions, a deduction
for his or her share of the foreign income taxes in computing federal income tax
liability. (No deduction will be permitted in computing an individual's
alternative minimum tax liability.) A shareholder who is a nonresident alien
individual or a foreign corporation may be subject to U.S. withholding tax on
the 
                                     SAI-27

income resulting from the election described in this paragraph,
but may not be able to claim a credit or deduction against
such U.S. tax for the foreign taxes treated as having been paid by such
shareholder. A tax-exempt shareholder will not ordinarily benefit from this
election. Shareholders who choose to utilize a credit (rather than a deduction)
for foreign taxes will be subject to the limitation that the credit may not
exceed the shareholder's U.S. tax (determined without regard to the availability
of the credit) attributable to his or her total foreign source taxable income.
For this purpose, the portion of dividends and distributions paid by the
International Equity Funds from their foreign source net investment income will
be treated as foreign source income. This Portfolio's gains and losses from the
sale of securities will generally be treated as derived from U.S. sources,
however, and certain foreign currency gains and losses likewise will be treated
as derived from U.S. sources. The limitation on the foreign tax credit is
applied separately to foreign source 'passive income', such as the portion of
dividends received from the Portfolio that qualifies as foreign source income.
In addition, the foreign tax credit is allowed to offset only 90% of the
alternative minimum tax imposed on corporations and individuals. Because of
these limitations, shareholders may be unable to claim a credit for the full
amount of their proportionate shares of the foreign income taxes paid by the
International Equity Portfolio.
    
 
     STATE AND LOCAL TAXES. Each Fund may be subject to state or local taxes in
jurisdictions in which that Fund is deemed to be doing business. In addition,
the treatment of a Fund and its shareholders in those states that have income
tax laws might differ from treatment under the federal income tax laws. For
example, a portion of the dividends received by shareholders may be subject to
state income tax. Shareholders should consult their own tax advisors with
respect to any state or local taxes.

UBS Bond Fund
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
 
1. GENERAL

UBS Bond Fund (the 'Fund') is a diversified, no-load mutual fund registered
under the Investment Company Act of 1940. The Fund is a series of UBS Private
Investor Funds, Inc. (the 'Company'), an open-end management investment company
organized as a corporation under Maryland law. At December 31, 1996, the Company
included two other funds, UBS U.S. Equity Fund and UBS International Equity
Fund. These financial statements relate only to the Fund.
 
The Fund had no operations prior to April 2, 1996 other than the sale to
Signature Financial Group, Inc. of 250 shares of common stock for $25,000.
 
The Fund seeks to achieve its investment objective by investing substantially
all of its investable assets in the UBS Bond Portfolio of UBS Investor
Portfolios Trust (the 'Portfolio'), an open-end management investment company
that has the same investment objective as that of the Fund.
 
Signature Broker-Dealer Services, Inc. ('Signature'), a wholly-owned subsidiary
of Signature Financial Group, Inc., serves as the Fund's administrator and
distributor. Union Bank of Switzerland, New York Branch ('UBS') serves as the
fund services agent to the Fund.
 
The financial statements of the Portfolio, including its Schedule of
Investments, are included elsewhere within this report and should be read in
conjunction with the Fund's financial statements.
 
2. SIGNIFICANT ACCOUNTING POLICIES

The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates. Significant accounting policies
followed by the Fund are as follows:
 
A. INVESTMENT VALUATION -- The value of the Fund's investment in the Portfolio
included in the accompanying Statement of Assets and Liabilities reflects the
Fund's proportionate beneficial interest in the net assets of the Portfolio
(14.3% at December 31, 1996). Valuation of securities by the Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements which are
included elsewhere in this report.
 
B. INVESTMENT INCOME, EXPENSES AND REALIZED AND UNREALIZED GAINS AND LOSSES --
The Fund records its share of the investment income, expenses and realized and
unrealized gains and losses recorded by the Portfolio on a daily basis. The
investment income, expenses and realized and unrealized gains and losses are
allocated daily to investors of the Portfolio based upon the amount of their
investment in the Portfolio.
 
C. FEDERAL TAXES -- The Fund's policy is to comply with the provisions of the
Internal Revenue Code applicable to regulated investment companies, including
the requirement to distribute substantially all of its taxable income, including
any net realized capital gains on investment transactions, to its shareholders.
Accordingly, no provision for federal income or excise taxes is necessary.
 
D. DIVIDENDS AND DISTRIBUTIONS -- The Fund declares dividends from net
investment income to shareholders of record on the day of declaration. Such
dividends are declared daily and paid monthly. Net realized gains, if any, will
be distributed at least annually. However, to the extent that net realized gains
of the Fund can be reduced by capital loss carryovers, such gains will not be
distributed. Dividends and distributions are recorded on the ex-dividend date.
 
The amounts of dividends from net investment income and distributions from net
realized gains are determined in accordance with federal income tax regulations
which may differ from generally accepted accounting principles. These 'book/tax'
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the composition of net assets based upon their federal tax-basis
treatment; temporary differences do not require reclassification. For

Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------

the fiscal year ended December 31, 1996, the Fund increased accumulated
undistributed net realized gains by $6,044, reduced accumulated undistributed
net investment income by $4,838 and decreased paid-in capital by $1,206. Net
investment income, net realized gains and net assets were not affected by this
change.
 
E. DEFERRED ORGANIZATION EXPENSES -- Expenses incurred by the Fund in connection
with its organization in the amount of $72,500 have been deferred and are being
amortized on a straight line basis over five years from the Fund's commencement
of operations (April 2, 1996).
 
F. OTHER -- The Fund bears all costs of its operations other than expenses
specifically assumed by Signature and UBS. Expenses incurred by the Company on
behalf of any two or more funds are allocated in proportion to the net assets of
each fund, except when allocations of direct expenses to each fund can otherwise
be made fairly. Expenses directly attributable to the Fund are charged directly
to the Fund.
 
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

A. ADMINISTRATIVE SERVICES AGREEMENT -- Under the terms of an Administrative
Services Agreement with the Company, Signature provides overall administrative
services and general office facilities. As compensation for such services, the
Company has agreed to pay Signature a fee, accrued daily and payable monthly, at
an annual rate of 0.05% of the Fund's first $100 million average daily net
assets and 0.025% of the next $100 million average daily net assets. Signature
does not receive a fee on average daily net assets in excess of $200 million.
For the period April 2, 1996 (commencement of operations) through December 31,
1996, the administrative services fee amounted to $1,526.
 
B. DISTRIBUTION AGREEMENT -- Under the terms of a Distribution Agreement,
Signature serves as the distributor of Fund shares. Signature does not receive
any additional fees for services provided pursuant to this agreement.
 
C. SHAREHOLDER SERVICES AGREEMENT -- The Fund has entered into a Shareholder
Services Agreement with UBS pursuant to which UBS provides certain services to
shareholders of the Fund. The Fund has agreed to pay UBS a fee for these
services, accrued daily and payable monthly, at an annual rate of 0.25% of the
average daily net assets of the Fund. For the period April 2, 1996 (commencement
of operations) through December 31, 1996, the shareholder service fee amounted
to $7,632, all of which was waived.
 
D. FUND SERVICES AGREEMENT -- Under the terms of a Fund Services Agreement with
the Company, UBS has agreed to provide certain administrative services to the
Fund. UBS is not entitled to any additional compensation pursuant to this
agreement.
 
E. EXPENSE REIMBURSEMENTS -- UBS has voluntarily agreed to limit the total
operating expenses of the Fund, including its share of the Portfolio's expenses
and excluding extraordinary expenses, to an annual rate of 0.80% of the Fund's
average daily net assets. For the period April 2, 1996 (commencement of
operations) through December 31, 1996, UBS reimbursed the Fund for expenses
totaling $80,050 in connection with this voluntary limitation. UBS may modify or
discontinue this voluntary expense limitation at any time with 30 days' advance
notice to the Fund.

To the Board of Directors and
Shareholders of UBS Private Investor Funds, Inc.
 
In our opinion, the accompanying statement of assets and liabilities, and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
the UBS Bond Fund (the 'Fund') (one of the funds constituting the UBS Private
Investor Funds, Inc.) at December 31, 1996, and the results of its operations,
the changes in its net assets and the financial highlights for the period April
2, 1996 (commencement of operations) through December 31, 1996, in conformity
with generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as 'financial statements') are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these financial statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for the opinion expressed above.

UBS Bond Portfolio
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
 
1. GENERAL

UBS Bond Portfolio (the 'Portfolio'), a separate series of UBS Investor
Portfolios Trust (the 'Trust'), is registered under the Investment Company Act
of 1940, as a diversified, open-end management investment company. The Trust is
organized as a trust under the laws of the State of New York.
 
The investment adviser of the Portfolio is Union Bank of Switzerland, New York
Branch ('UBS'). Signature Financial Group (Grand Cayman), Ltd. ('SFG'), a
wholly-owned subsidiary of Signature Financial Group, Inc., acts as the
Portfolio's administrator and placement agent.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
The preparation of financial statements in accordance with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts and disclosures in the
financial statements. Actual results could differ from those estimates. The
following is a summary of significant accounting policies followed by the
Portfolio in the preparation of its financial statements:
 
A. INVESTMENT VALUATION -- Debt securities with a remaining maturity of more
than 60 days are normally valued by a pricing service approved by the Board of
Trustees (the 'Trustees'). Such pricing service will consider various factors
when arriving at a valuation for a security. Such factors include yields and
prices of comparable securities, indications as to values from dealers in such
securities and general market conditions. In the event a pricing service is
unable to price a security, the security will be valued by taking the average of
the bid and ask prices as provided by a dealer in such security.
 
Debt securities that mature in 60 days or less are valued at amortized cost,
which approximates market value. The amortized cost method involves valuing a
security at its cost on the date of purchase or, in the case of securities
purchased with more than 60 days until maturity, at their market value each day
until the 61st day prior to maturity, and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and such valuation.
 
Securities or other assets for which market quotations are not readily available
are valued at fair value in accordance with procedures established by and under
the general supervision of the Trustees.
 
B. FOREIGN CURRENCY TRANSLATION -- The accounting records of the Portfolio are
maintained in U.S. dollars. Assets, including investment securities, and
liabilities denominated in foreign currency are translated into U.S. dollars at
the prevailing rate of exchange at year end. Purchases and sales of securities,
income and expenses are translated at the prevailing rate of exchange on the
respective dates of such transactions. Gain/loss on translation of foreign
currency includes net exchange gains and losses, gains and losses on disposition
of foreign currency and adjustments to the amount of foreign taxes withheld.
 
The assets and liabilities are presented at the exchange rates and market values
at the close of the year. The changes in net assets arising from changes in
exchange rates and the changes in net assets resulting from changes in market
prices of securities held at year-end are not separately presented. However,
gains and losses from certain foreign currency transactions are treated as
ordinary income for U.S. Federal income tax purposes.
 
C. FORWARD FOREIGN CURRENCY CONTRACTS -- The Portfolio may enter into forward
foreign currency contracts in connection with planned purchases or sales of
securities or to hedge the U.S. dollar value of portfolio securities denominated
in a particular currency. The Portfolio could be exposed to risks if the
counterparties to the contracts are unable to meet the terms of their contracts
and from unanticipated movements in the value of a foreign currency relative to
the U.S. dollar. The forward foreign currency contracts are marked-to-market
daily using the daily exchange rate of the underlying currency and any resulting
gains or losses are recorded for financial statement purposes as unrealized
gains or losses until the contract settlement date.

UBS Bond Portfolio
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
 
The Portfolio's use of forward contracts involves, to varying degrees, elements
of market risk in excess of the amount recognized in the statement of assets and
liabilities. The contract or notional amounts reflect the extent of the
Portfolio's involvement in these financial instruments. Risks arise from the
possible movements in the foreign exchange rates underlying these instruments.
The unrealized appreciation/depreciation on forward contracts reflects the
Portfolio's exposure at year end to credit loss in the event of a counterparty's
failure to perform its obligations.
 
D. ACCOUNTING FOR INVESTMENTS -- Securities transactions are accounted for on
trade date. Realized gains and losses on security transactions are determined on
the identified cost basis. Interest income, adjusted for amortization of
premiums and accretion of discounts on investments, is accrued daily.
 
E. U.S. FEDERAL INCOME TAXES -- The Portfolio is considered a partnership under
the U. S. Internal Revenue Code (the 'Code'). As such, each investor in the
Portfolio will be taxed on its share of the Portfolio's ordinary income and
capital gains. Accordingly, no provision for federal income taxes is necessary.
It is intended that the Portfolio will be managed in such a way that an investor
will be able to satisfy the requirements of the Code applicable to regulated
investment companies.
 
F. DEFERRED ORGANIZATION EXPENSES -- Expenses incurred by the Portfolio in
connection with its organization in the amount of $50,000 have been deferred and
are being amortized on a straight line basis over five years from the
Portfolio's commencement of operations (April 2, 1996).
 
G. OTHER -- The Portfolio bears all costs of its operations other than expenses
specifically assumed by UBS and SFG. Expenses incurred by the Trust on behalf of
any two or more portfolios are allocated in proportion to the net assets of each
portfolio, except when allocations of direct expenses to each portfolio can
otherwise be made fairly. Expenses directly attributable to the Portfolio are
charged directly to the Portfolio.
 
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES
 
A. INVESTMENT ADVISORY AGREEMENT -- The Portfolio has retained the services of
UBS as investment adviser. UBS makes the Portfolio's day-to-day investment
decisions, arranges for the execution of portfolio transactions and generally
manages the Portfolio's investments and operations. As compensation for overall
investment management services the Trust has agreed to pay UBS an investment
advisory fee, accrued daily and payable monthly, at an annual rate of 0.45% of
the Portfolio's average daily net assets. For the period April 2, 1996
(commencement of operations) through December 31, 1996, UBS voluntarily agreed
to waive the entire investment advisory fee. Such waiver amounted to $131,348.
 
B. ADMINISTRATIVE SERVICES AGREEMENT -- Under the terms of an Administrative
Services Agreement with the Trust, SFG provides overall administrative services
and general office facilities to the Portfolio and the Trust. As compensation
for such services, the Portfolio has agreed to pay SFG an administrative
services fee, accrued daily and payable monthly, at an annual rate of 0.05% of
the Portfolio's average daily net assets. For the period from April 2, 1996

UBS BOND PORTFOLIO
REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------
 
To the Board of Trustees and
Investors of UBS Investor Portfolios Trust
 
In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the UBS Bond Portfolio (the
'Portfolio') (one of the portfolios constituting the UBS Investor Portfolios
Trust) at December 31, 1996, and the results of its operations, the changes in
its net assets and the financial highlights for the period April 2, 1996
(commencement of operations) through December 31, 1996, in conformity with
generally accepted accounting principles in the United States. These financial
statements and financial highlights (hereafter referred to as 'financial
statements') are the responsibility of the Portfolio's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these financial statements in accordance
with generally accepted auditing standards in the United States which require
that we plan and perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit, which included confirmation
of securities at December 31, 1996 by correspondence with the custodian,
provides a reasonable basis for the opinion expressed above.

- --------------------------------------------------------------------------------
    
 
   
1. GENERAL
    
   
UBS U.S. Equity Fund (the 'Fund') is a diversified, no-load mutual fund
registered under the Investment Company Act of 1940. The Fund is a series of UBS
Private Investor Funds, Inc. (the 'Company'), an open-end management investment
company organized as a corporation under Maryland law. At December 31, 1996, the
Company included two other funds, UBS Bond Fund and UBS International Equity
Fund. These financial statements relate only to the Fund.
    
 
   
The Fund had no operations prior to April 2, 1996 other than the sale to
Signature Financial Group, Inc. of 250 shares of common stock for $25,000.
    
 
   
The Fund seeks to achieve its investment objective by investing substantially
all of its investable assets in the UBS U.S. Equity Portfolio of UBS Investor
Portfolios Trust (the 'Portfolio'), an open-end management investment company
that has the same investment objective as that of the Fund.
    
 
   
Signature Broker-Dealer Services, Inc. ('Signature'), a wholly-owned subsidiary
of Signature Financial Group, Inc., serves as the Fund's administrator and
distributor. Union Bank of Switzerland, New York Branch ('UBS') serves as the

The financial statements of the Portfolio, including its Schedule of
Investments, are included elsewhere within this report and should be read in
conjunction with the Fund's financial statements.
    
 
   
2. SIGNIFICANT ACCOUNTING POLICIES
    
   
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates. Significant accounting policies
followed by the Fund are as follows:
    
 
   
A. INVESTMENT VALUATION -- The value of the Fund's investment in the Portfolio
included in the accompanying Statement of Assets and Liabilities reflects the
Fund's proportionate beneficial interest in the net assets of the Portfolio
(37.3% at December 31, 1996). Valuation of securities by the Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements which are
included elsewhere in this report.
    
 
   
B. INVESTMENT INCOME, EXPENSES AND REALIZED AND UNREALIZED GAINS AND LOSSES --
The Fund records its share of the investment income, expenses and realized and
unrealized gains and losses recorded by the Portfolio on a daily basis. The
investment income, expenses and realized and unrealized gains and losses are
allocated daily to investors of the Portfolio based upon the amount of their
investment in the Portfolio.
    
 
   
C. FEDERAL TAXES -- The Fund's policy is to comply with the provisions of the
Internal Revenue Code applicable to regulated investment companies, including
the requirement to distribute substantially all of its taxable income, including
any net realized capital gains on investment transactions, to its shareholders.
Accordingly, no provision for federal income or excise taxes is necessary.
    
 
   
D. DIVIDENDS AND DISTRIBUTIONS -- The Fund declares dividends from net
investment income to shareholders of record on the day of declaration. Such
dividends are declared and paid annually. Net realized gains, if any, will be
distributed at least annually. However, to the extent that net realized gains of
the Fund can be reduced by capital loss carryovers, such gains will not be
distributed. Dividends and distributions are recorded on the ex-dividend date.
    
 
   
The amounts of dividends from net investment income and distributions from net
realized gains are determined in accordance with federal income tax regulations
which may differ from generally accepted accounting principles. These 'book/tax'
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the composition of net assets based upon their federal tax-basis
treatment; temporary differences do not require reclassification.

E. DEFERRED ORGANIZATION EXPENSES -- Expenses incurred by the Fund in connection
with its organization in the amount of $72,500 have been deferred and are being
amortized on a straight line basis over five years from the Fund's commencement
of operations (April 2, 1996).
    
 
   
F. OTHER -- The Fund bears all cost of its operations other than expenses
specifically assumed by UBS and Signature. Expenses incurred by the Company on
behalf of any two or more funds are allocated in proportion to the net assets of
each fund, except when allocations of direct expenses to each fund can otherwise
be made fairly. Expenses directly attributable to the Fund are charged directly
to the Fund.
    
 
   
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES
    
   
A. ADMINISTRATIVE SERVICES AGREEMENT -- Under the terms of an Administrative
Services Agreement with the Company, Signature provides overall administrative
services and general office facilities. As compensation for such services, the
Company has agreed to pay Signature a fee, accrued daily and payable monthly, at
an annual rate of 0.05% of the Fund's first $100 million average daily net
assets and 0.025% of the next $100 million average daily net assets. Signature
does not receive a fee on average net assets in excess of $200 million. For the
period April 2, 1996 (commencement of operations) through December 31, 1996, the
administrative services fee amounted to $2,593.
    
 
   
B. DISTRIBUTION AGREEMENT -- Under the terms of a Distribution Agreement with
the Company, Signature serves as the distributor of Fund shares. Signature does
not receive any additional fees for services provided pursuant to this
agreement.
    
 
   
C. SHAREHOLDER SERVICES AGREEMENT -- The Fund has entered into a Shareholder
Services Agreement with UBS pursuant to which UBS provides certain services to
shareholders of the Fund. The Fund has agreed to pay UBS a fee for these
services, accrued daily and payable monthly, at an annual rate of 0.25% of the
average daily net assets of the Fund. For the period April 2, 1996 (commencement
of operations) through December 31, 1996, the shareholder service fee amounted
to $12,965, all of which was waived.
    
 
   
D. FUND SERVICES AGREEMENT -- Under the terms of a Fund Services Agreement with
the Company, UBS has agreed to provide certain administrative services to the
Fund. UBS is not entitled to any additional compensation pursuant to this
agreement.
    
 
   
E. EXPENSE REIMBURSEMENTS -- UBS has voluntarily agreed to limit the total
operating expenses of the Fund, including its share of the Portfolio's expenses
and excluding extraordinary expenses, to an annual rate of 0.90% of the Fund's
average daily net assets. For the period April 2, 1996 (commencement of
operations) through December 31, 1996, UBS reimbursed the Fund for expenses
totaling $93,511 in connection with this voluntary limitation. UBS may modify or
discontinue this voluntary expense limitation at any time with 30 days' advance
notice to the Fund.

To the Board of Directors and
Shareholders of UBS Private Investor Funds, Inc.
    
 
   
In our opinion, the accompanying statement of assets and liabilities and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
the UBS U.S. Equity Fund (the 'Fund') (one of the funds constituting the UBS
Private Investor Funds, Inc.) at December 31, 1996, and the results of its
operations, the changes in its net assets and the financial highlights for the
period April 2, 1996 (commencement of operations) through December 31, 1996, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as 'financial
statements') are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audit. We
conducted our audit of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for the opinion expressed above.

UBS U.S. Equity Portfolio
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
    
 
   
1. GENERAL
    
   
UBS U.S. Equity Portfolio (the 'Portfolio'), a separate series of UBS Investor
Portfolios Trust (the 'Trust'), is registered under the Investment Company Act
of 1940, as a diversified, open-end management investment company. The Trust is
organized as a trust under the laws of the State of New York.
    
 
   
The investment adviser of the Portfolio is Union Bank of Switzerland, New York
Branch ('UBS'). Signature Financial Group (Grand Cayman), Ltd. ('SFG'), a
wholly-owned subsidiary of Signature Financial Group, Inc., acts as the
Portfolio's administrator and placement agent.
    
 
   
2. SIGNIFICANT ACCOUNTING POLICIES
    
   
The preparation of financial statements in accordance with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts and disclosures in the
financial statements. Actual results could differ from those estimates. The
following is a summary of significant accounting policies followed by the
Portfolio in the preparation of its financial statements:
    
 
   
A. INVESTMENT VALUATION -- Equity securities in the portfolio are valued at
their last sale price on the exchange on which they are primarily traded, or in
the absence of recorded sales, at the average of readily available closing bid
and asked prices, or at the quoted bid price. Unlisted securities are valued at
the average of the quoted bid and asked prices in the over-the-counter market.
    
 
   
Options on stock indices traded on national securities exchanges are valued at
their last sale price as of the close of options trading on such exchanges.
Stock index futures and related options traded on commodities exchanges are
valued at their last sales price as of the close of such exchanges.
    
 
   
Securities or other assets for which market quotations are not readily available
are valued at fair value in accordance with procedures established by and under
the general supervision of the Portfolio's Board of Trustees (the 'Trustees').
    
 
   
Debt securities that mature in 60 days or less are valued at amortized cost,
which approximates market value. The amortized cost method involves valuing a
security at its cost on the date of purchase or, in the case of securities
purchased with more than 60 days until maturity, at their market value each day
until the 61st day prior to maturity, and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and such valuation.
    
 
   
B. ACCOUNTING FOR INVESTMENTS -- Securities transactions are accounted for on
trade date. Realized gains and losses on security transactions are determined on
the identified cost basis. Dividend income and other distributions from
portfolio securities are recorded on the ex-dividend date. Interest income,
adjusted for amortization of premiums and accretion of discounts on investments,
is accrued daily.
    
 
   
C. U. S. FEDERAL INCOME TAXES -- The Portfolio is considered a partnership under
the U. S. Internal Revenue Code (the 'Code'). As such, each investor in the
Portfolio will be taxed on its share of the Portfolio's ordinary income and
capital gains. Accordingly, no provision for federal income taxes is necessary.
It is intended that the Portfolio will be managed in such a way that an investor
will be able to satisfy the requirements of the Code applicable to regulated
investment companies.
    
 
   
D. DEFERRED ORGANIZATION EXPENSES -- Expenses incurred by the Portfolio in
connection with its organization in the amount of $50,000 have been deferred and
are being amortized on a straight line basis over five years from the
Portfolio's commencement of operations (April 2, 1996).
    
 
   
E. OTHER -- The Portfolio bears all costs of its operations other than expenses
specifically assumed by UBS and SFG. Expenses incurred by the Trust on behalf of
any two or more portfolios are allocated in proportion to the
    
 
                                     SAI-60

net assets of each portfolio, except when allocations of direct expenses to each
portfolio can otherwise be made fairly. Expenses directly attributable to the
Portfolio are charged directly to the Portfolio.
    
 
   
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES
    
   
A. INVESTMENT ADVISORY AGREEMENT -- The Portfolio has retained the services of
UBS as investment adviser. UBS makes the Portfolio's day-to-day investment
decisions, arranges for the execution of portfolio transactions and generally
manages the Portfolio's investments and operations. As compensation for overall
investment management services the Trust has agreed to pay UBS an investment
advisory fee, accrued daily and payable monthly, at an annual rate of 0.60% of
the Portfolio's average daily net assets. For the period April 2, 1996
(commencement of operations) through December 31, 1996, UBS voluntarily agreed
to waive the entire investment advisory fee. Such waiver amounted to $84,435.
    
 
   
B. ADMINISTRATIVE SERVICES AGREEMENT -- Under the terms of an Administrative
Services Agreement with the Trust, SFG provides overall administrative services
and general office facilities to the Portfolio and the Trust. As compensation
for such services, the Portfolio has agreed to pay SFG an administrative
services fee, accrued daily and payable monthly, at an annual rate of 0.05% of
the Portfolio's average daily net assets. For the period April 2, 1996
(commencement of operations) through December 31, 1996, the administrative
services fee amounted to $7,036.
    
 
   
C. EXCLUSIVE PLACEMENT AGENT AGREEMENT -- Under the terms of an Exclusive
Placement Agent Agreement with the Trust, SFG has agreed to act as the Trust's
placement agent. SFG does not receive any additional fees for services provided
pursuant to this agreement.
    
 
   
4. PURCHASES AND SALES OF INVESTMENTS
    
   
For the period April 2, 1996 (commencement of operations) through December 31,
1996, purchases and sales of investment securities, excluding short-term
investments, aggregated $26,712,324 and $3,569,719, respectively.

statements') are the responsibility of the Portfolio's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these financial statements in accordance
with generally accepted auditing standards in the United States which require
that we plan and perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit, which included confirmation
of securities at December 31, 1996 by correspondence with the custodian and
brokers, provides a reasonable basis for the opinion expressed above.

UBS International Equity Fund
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
    
 
   
1. GENERAL
    
   
UBS International Equity Fund (the 'Fund') is a diversified, no-load mutual fund
registered under the Investment Company Act of 1940. The Fund is a series of UBS
Private Investor Funds, Inc. (the 'Company'), an open-end management investment
company organized as a corporation under Maryland law. At December 31, 1996, the
Company included two other funds, UBS Bond Fund and UBS U.S. Equity Fund. These
financial statements relate only to the Fund.
    
 
   
The Fund had no operations prior to April 2, 1996 other than the sale to
Signature Financial Group, Inc. of 250 shares of common stock for $25,000.
    
 
   
The Fund seeks to achieve its investment objective by investing substantially
all of its investable assets in the UBS International Equity Portfolio of UBS
Investor Portfolios Trust (the 'Portfolio'), an open-end management investment
company that has the same investment objective as that of the Fund.
    
 
   
Signature Broker-Dealer Services, Inc. ('Signature'), a wholly-owned subsidiary
of Signature Financial Group, Inc., serves as the Fund's administrator and
distributor. Union Bank of Switzerland, New York Branch ('UBS') serves as the
fund services agent to the Fund.
    
 
   
The financial statements of the Portfolio, including its Schedule of
Investments, are included elsewhere within this report and should be read in
conjunction with the Fund's financial statements.
    
 
   
2. SIGNIFICANT ACCOUNTING POLICIES
    
   
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates. Significant accounting policies
followed by the Fund are as follows:
    
 
   
A. INVESTMENT VALUATION -- The value of the Fund's investment in the Portfolio
included in the accompanying Statement of Assets and Liabilities reflects the
Fund's proportionate beneficial interest in the net assets of the Portfolio
(64.0% at December 31, 1996). Valuation of securities by the Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements which are
included elsewhere in this report.
    
 
   
B. INVESTMENT INCOME, EXPENSES AND REALIZED AND UNREALIZED GAINS AND LOSSES --
The Fund records its share of the investment income, expenses and realized and
unrealized gains and losses recorded by the Portfolio on a daily basis. The
investment income, expenses and realized and unrealized gains and losses are
allocated daily to investors of the Portfolio based upon the amount of their
investment in the Portfolio. The amount of foreign withholding taxes deducted
from the dividend income allocated to the Fund from the Portfolio is net of
amounts the Fund expects to recover from foreign tax authorities.
    
 
   
C. FEDERAL TAXES -- The Fund's policy is to comply with the provisions of the
Internal Revenue Code applicable to regulated investment companies, including
the requirement to distribute substantially all of its taxable income, including
any net realized capital gains on investment transactions, to its shareholders.
Accordingly, no provision for federal income or excise taxes is necessary.
    
 
   
D. DIVIDENDS AND DISTRIBUTIONS -- The Fund declares dividends from net
investment income to shareholders of record on the day of declaration. Such
dividends are declared and paid annually. Net realized gains, if any, will be
distributed at least annually. However, to the extent that net realized gains of
the Fund can be reduced by capital loss carryovers, such gains will not be
distributed. Dividends and distributions are recorded on the ex-dividend date.
    
 
   
The amounts of dividends from net investment income and distributions from net
realized gains are determined in accordance with federal income tax regulations
which may differ from generally accepted

accounting principles. These 'book/tax' differences are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the composition of net assets
based upon their federal tax-basis treatment; temporary differences do not
require reclassification. For the fiscal year ended December 31, 1996, the Fund
increased accumulated undistributed net investment income by $7,723, decreased
accumulated undistributed net realized gains by $2,984 and decreased paid-in
capital by $4,739. Net investment income, net realized gains and net assets were
not affected by this change.
    
 
   
E. DEFERRED ORGANIZATION EXPENSES -- Expenses incurred by the Fund in connection

In our opinion, the accompanying statement of assets and liabilities and the
related statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
the UBS International Equity Fund (the 'Fund') (one of the funds constituting
UBS Private Investor Funds, Inc.) at December 31, 1996, and the results of its
operations, the changes in its net assets and the financial highlights for the
period April 2, 1996 (commencement of operations) through December 31, 1996, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as 'financial
statements') are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audit. We
conducted our audit of these financial statements in accordance with generally
accepted auditing standards which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for the opinion expressed above.

UBS International Equity Portfolio
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
    
 
   
1. GENERAL
    
   
UBS International Equity Portfolio (the 'Portfolio'), a separate series of UBS
Investor Portfolios Trust (the 'Trust'), is registered under the Investment
Company Act of 1940, as a diversified, open-end management investment company.
The Trust is organized as a trust under the laws of the State of New York.
    
 
   
The investment adviser of the Portfolio is Union Bank of Switzerland, New York
Branch ('UBS'); UBS International Investment London Limited ('UBSII') is the
sub-adviser of the Portfolio. Signature Financial Group (Grand Cayman), Ltd.
('SFG'), a wholly-owned subsidiary of Signature Financial Group, Inc., acts as
the Portfolio's administrator and placement agent.
    
 
   
2. SIGNIFICANT ACCOUNTING POLICIES
    
   
The preparation of financial statements in accordance with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts and disclosures in the
financial statements. Actual results could differ from those estimates. The
following is a summary of significant accounting policies followed by the
Portfolio in the preparation of its financial statements:
    
 
   
A. INVESTMENT VALUATION -- Equity securities in the portfolio are valued at the
last sale price on the exchange on which they are primarily traded, or in the
absence of recorded sales, at the average of readily available closing bid and
asked prices, or at the quoted bid price. Unlisted securities are valued at the
average of the quoted bid and asked prices in the over-the-counter market.
    
 
   
Options on stock indices traded on national securities exchanges are valued at
their last sale price as of the close of options trading on such exchanges.
Stock index futures and related options traded on commodities exchanges are
valued at their last sales price as of the close of trading on such exchanges.
    
 
   
Securities or other assets for which market quotations are not readily available
are valued at fair value in accordance with procedures established by and under
the general supervision of the Portfolio's Board of Trustees (the 'Trustees').
    
 
   
Debt securities that mature in 60 days or less are valued at amortized cost,
which approximates market value. The amortized cost method involves valuing a
security at its cost on the date of purchase or, in the case of securities
purchased with more than 60 days until maturity, at their market value each day
until the 61st day prior to maturity, and thereafter assuming a constant
amortization to maturity of the difference between the principal amount due at
maturity and such valuation.
    
 
   
Trading in securities on most foreign exchanges and over-the-counter markets is
normally completed before the close of the New York Stock Exchange and may also
take place on days on which the New York Stock Exchange is closed. If events
materially affecting the value of foreign securities occur between the time when
the exchange on which they are traded closes and the pricing of the Portfolio,
such securities will be valued at fair value in accordance with procedures
established by and under the general supervision of the Trustees.
    
 
   
B. FOREIGN CURRENCY TRANSLATION -- The accounting records of the Portfolio are
maintained in U.S. dollars. Assets, including investment securities, and
liabilities denominated in foreign currency are translated into U.S. dollars at
the prevailing rate of exchange at year end. Purchases and sales of securities,
income and expenses are translated at the prevailing rate of exchange on the
respective dates of such transactions. Gain/loss on translation of foreign
currency includes net exchange gains and losses, gains and losses on disposition
of foreign currency and adjustments to the amount of foreign taxes withheld.
    
 
   
The assets and liabilities are presented at the exchange rates and market values
at the close of the year. The changes in net assets arising from changes in
exchange rates and the changes in net assets resulting from changes in market
prices of securities at year end are not separately presented. However, gains
and losses from certain foreign currency transactions are treated as ordinary
income for U.S. Federal income tax purposes.
    
 
   
C. FORWARD FOREIGN CURRENCY CONTRACTS -- The Portfolio may enter into forward
foreign currency contracts in connection with planned purchases or sales of
securities or to hedge the U.S. dollar value of portfolio securities denominated
in a particular currency. The Portfolio could be exposed to risks if the
counterparties to the contracts are unable to meet the terms of their contracts
and from unanticipated movements in the value of a foreign currency relative to
the U.S. dollar. The forward foreign currency contracts are marked-to-market
daily using the daily exchange rate of the underlying currency and any resulting
gains or losses are recorded for financial statement purposes as unrealized
gains or losses until the contract settlement date.

UBS International Equity Portfolio
Notes to Financial Statements
December 31, 1996
- --------------------------------------------------------------------------------
 
   
The Portfolio's use of forward contracts involves, to varying degrees, elements
of market risk in excess of the amount recognized in the statement of assets and
liabilities. The contract or notional amounts reflect the extent of the
Portfolio's involvement in these financial instruments. Risks arise from the
possible movements in the foreign exchange rates underlying these instruments.
The unrealized appreciation/depreciation on forward contracts reflects the
Portfolio's exposure at year end to credit loss in the event of a counterparty's
failure to perform its obligations.
    
 
   
D. ACCOUNTING FOR INVESTMENTS -- Securities transactions are accounted for on
trade date. Realized gains and losses on security transactions are determined on
the identified cost basis. Dividend income and other distributions from
portfolio securities are recorded on the ex-dividend date, except, if the
ex-dividend date has passed, certain dividends from foreign securities are
recorded as soon as the Portfolio is informed of the ex-dividend date. Dividend
income is recorded net of foreign taxes withheld where recovery of such taxes is
not assured. Withholding taxes on foreign dividends have been provided for in
accordance with the Portfolio's understanding of the applicable countries' tax
rules and rates. Recoveries of foreign taxes withheld from the Portfolio's
income are generally recorded, where applicable, by the funds investing in the
Portfolio. Interest income, adjusted for amortization of premiums and accretion
of discounts on investments, is accrued daily.
    
 
   
E. U. S. FEDERAL INCOME TAXES -- The Portfolio is considered a partnership under
the U.S. Internal Revenue Code (the 'Code'). As such, each investor in the
Portfolio will be taxed on its share of the Portfolio's ordinary income and
capital gains. Accordingly, no provision for federal income taxes is necessary.
It is intended that the Portfolio will be managed in such a way that an investor
will be able to satisfy the requirements of the Code applicable to regulated
investment companies.
    
 
   
F. DEFERRED ORGANIZATION EXPENSES -- Expenses incurred by the Portfolio in
connection with its organization in the amount of $50,000 have been deferred and
are being amortized on a straight line basis over five years from the
Portfolio's commencement of operations (April 2, 1996).
    
 
   
G. OTHER -- The Portfolio bears all costs of its operations other than expenses
specifically assumed by UBS and SFG. Expenses incurred by the Trust on behalf of
any two or more portfolios are allocated in proportion to net assets of each
portfolio, except when allocations of direct expenses to each portfolio can
otherwise be made fairly. Expenses directly attributable to the Portfolio are
charged directly to the Portfolio.
    
 
   
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES
    
   
A. INVESTMENT ADVISORY AGREEMENT -- The Portfolio has retained the services of
UBS as investment adviser and UBSII as investment sub-adviser. UBSII makes the
Portfolio's day-to-day investment decisions, arranges for the execution of
portfolio transactions and generally manages the Portfolio's investments and
operations subject to the supervision of UBS and the Trustees. As compensation
for overall investment management services the Trust has agreed to pay UBS an
investment advisory fee, accrued daily and payable monthly, at an annual rate of
0.85% of the Portfolio's average daily net assets. UBS, in turn, has agreed to

UBS International Equity Portfolio
Report of Independent Accountants
- --------------------------------------------------------------------------------
    
 
   
To the Board of Trustees and
Investors of UBS Investor Portfolios Trust
    
 
   
In our opinion, the accompanying statement of assets and liabilities, including
the schedule of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the UBS International Equity
Portfolio (the 'Portfolio') (one of the portfolios constituting the UBS Investor
Portfolios Trust) at December 31, 1996, and the results of its operations, the
changes in its net assets and the financial highlights for the period April 2,
1996 (commencement of operations) through December 31, 1996, in conformity with
generally accepted accounting principles in the United States. These financial
statements and financial highlights (hereafter referred to as 'financial
statements') are the responsibility of the Portfolio's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these financial statements in accordance
with generally accepted auditing standards in the United States which require
that we plan and perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audit, which included confirmation
of securities at December 31, 1996 by correspondence with the custodian and
brokers, and the application of alternative auditing procedures where
confirmations from brokers were not received provides a reasonable basis for the
opinion expressed above.
