INVESTORS FOR WHOM THE FUNDS ARE DESIGNED
 

GENERAL

 
This Prospectus describes the investment objectives and policies, management and
operations of the Funds to enable investors to decide if the Funds suit their
investment needs. Because the investment characteristics and experience of the
Funds will correspond directly with those of the Portfolios, the discussion in
this section of the Prospectus focuses on the investments and investment
policies of the Portfolios. There is no assurance that a Fund or its
corresponding Portfolio will achieve its stated objective.
 
Each Portfolio is a series of the Trust, an open-end management investment
company. Each Portfolio has the same investment objective as its respective
Fund. The net asset values of shares of each Fund fluctuate with changes in the
value of the investments in such Fund's respective Portfolio.
 
The minimum initial investment in each 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 for all investors is $5,000. These minimums
may be waived at a Fund's discretion. See 'Purchase of Shares.' If shareholders
reduce their total investment in shares of a Fund to less than $10,000, their
investment will be subject to mandatory redemption. See 'Redemption of
Shares -- Mandatory Redemption.' Each Fund is one of several series of the
Company, an open-end management investment company organized as a Maryland
corporation.
 
UBS VALUE EQUITY FUND
 

The Value Equity Fund (formerly the UBS 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 volatility than is
normally available from common stock funds. In order to accomplish this, the
Adviser intends to invest in undervalued stocks having above market dividend
yields with emphasis on those securities which have the potential for long-term
earnings growth and increasing dividend payments. It is the intention of the
Adviser that the average dividend yield of the common stocks held by the Value
Equity Fund will exceed that of the Standard and Poor's 500 Composite Stock
Price Index (the 'S&P 500 Index') and have less price volatility than the S&P
500 Index.

 
Because of the risks associated with common stock investments, the Value Equity
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 Value Equity Fund seeks to achieve its investment objective by investing all
of its investable assets in the Value Equity Portfolio.
 

The Value Equity Portfolio may make various types of investments in seeking its
objective. Among the permissible investments for the Value Equity Portfolio are
equity securities of domestic issuers, including common stocks and securities
which are convertible into common stocks. The Value Equity Portfolio may also
invest in futures contracts, options and certain privately placed securities.
The Value Equity 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 Objectives and Policies' discussed below.

 
UBS INTERNATIONAL EQUITY FUND
 
The International Equity Fund seeks to provide a high total return from a
portfolio of equity securities of foreign corporations. It is designed for
investors with a long-term investment horizon who want to diversify their
investments by adding international equities and thereby take advantage of
investment opportunities outside the United States. The International Equity
Fund seeks to achieve its investment objective by investing all of its
investable assets in the International Equity Portfolio.
 
The International Equity Portfolio may make various types of investments in
seeking its objective. Among the permissible investments for the International
Equity Portfolio are common stocks and other securities with equity
characteristics issued by foreign companies. The International Equity Portfolio
may also invest in futures contracts, options, forward contracts on foreign
currencies and certain privately
 
                                      -2-

<PAGE>

placed securities. The International Equity Portfolio's investments in
securities of foreign issuers, including issuers in emerging markets, involve
unique investment risks and may be more volatile and less liquid than the
securities of domestic issuers. For further information about these investments
and related investment techniques, see 'Investment Objectives and Policies'
discussed below.

 
UBS LARGE CAP GROWTH FUND
 
The Large Cap Growth Fund seeks to provide long-term capital appreciation. In
order to accomplish this, the Adviser intends to invest primarily in a
diversified portfolio of common stocks and other equity securities of companies
that have stock market capitalizations at the time of initial purchase that are
within the market capitalization range of those stocks listed on the S&P 500
Index and that the Adviser believes will have above-average earnings and cash
flow growth or meaningful increases in underlying asset values over time.
 
Because of the risks associated with common stock investments, the Large Cap
Growth 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 Large Cap Growth Fund seeks to achieve its investment objective
by investing all of its investable assets in the Large Cap Growth Portfolio.
 

The Large Cap Growth Portfolio may make various types of investments in seeking
its objective. Among the permissible investments for the Large Cap Growth
Portfolio are equity securities of domestic issuers, including common stocks and
securities convertible into common stocks. The Large Cap Growth 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 Objectives and Policies' discussed below.

 
UBS SMALL CAP FUND
 
The Small Cap Fund seeks to provide long-term capital appreciation. In order to
accomplish this, the Adviser intends to invest primarily in a diversified
portfolio of common stocks and other equity securities of small capital growth
companies that the Adviser believes 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 listed on the Russell 2000 Index 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. It may also include providers of
products or services with a high unit volume growth rate.
 
Because of the risks associated with common stock investments, the Small Cap
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 Small Cap Fund seeks to achieve its investment objective by investing all of
its investable assets in the Small Cap Portfolio.
 

The Small Cap Portfolio may make various types of investments in seeking its
objective. Among the permissible investments for the Small Cap Portfolio are
equity securities of domestic issuers, including common stocks and securities
convertible into common stocks. The Small Cap Portfolio may also invest in
futures contracts, options and certain privately placed securities. The Small
Cap 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 Objectives and
Policies' discussed below.

 
The following table illustrates that Fund investors incur no shareholder
transaction expenses: their investments in the Funds are subject only to the
operating expenses set forth below for the Funds and the Portfolios,
respectively, as a percentage of average daily net assets of such Fund. The
Directors believe that the aggregate per share expenses of each Fund and its
corresponding Portfolio will be approximately equal to and may be less than the
expenses that such Fund would incur if it retained the services of an investment
adviser and invested its assets directly in portfolio securities. Expenses for
each Fund and Portfolio are discussed below under the headings 'Management,'
'Expenses' and 'Shareholder Services.'

*   Expenses are expressed as a percentage of a Fund's average daily net assets
and are based on the expenses actually incurred during the fiscal year ended
December 31, 1997, for the Value Equity Fund and the International Equity Fund,
and expected to be incurred during the fiscal year ending December 31, 1998, for
the Large Cap Growth Fund and Small Cap Fund, after any applicable fee waivers
and expense reimbursements. Without such fee waivers and expense reimbursements,
Total Operating Expenses were equal, on an annual basis, to: (i) 1.86% of the
Value Equity Fund's average daily net assets; and (ii) 2.13% of the
International Equity Fund's average daily net assets; and are expected to be
equal, on an annual basis, to: (iii) 3.62% of the Large Cap Growth Fund's
average daily net assets; and (iv) 2.14% of the Small Cap Fund's average daily
net assets. See 'Management.'

 

**  The Adviser has agreed to waive fees and reimburse each of the Funds and
their respective Portfolios for any of their respective operating expenses to
the extent that each such Fund's total operating expenses (including its share
of its respective Portfolio's expenses) exceed, on an annual basis: (i) 1.00% of
the Value Equity Fund's average daily net assets; (ii) 1.40% of the
International Equity Fund's average daily net assets; (iii) 1.00% of the Large
Cap Growth Fund's average daily net assets; and (iv) 1.20% of the Small Cap
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.

 
If there were no fee waiver in effect, each respective Portfolio's advisory fee
would be equal, on an annual basis, to: (i) 0.60% of the average daily net
assets of the Value Equity Portfolio; (ii) 0.85% of the average daily net assets
of the International Equity Portfolio; (iii) 0.60% of the average daily net
assets of the Large Cap Growth Portfolio; and (iv) 0.60% of the average daily
net assets of the Small Cap Portfolio. 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 Funds, (b) as
custodian of the Funds and the Portfolios and (c) as transfer agent of the
Funds;
 
(ii) IBT Trust and Custodial Services (Ireland) LMTD ('IBT Ireland') under an
Administration Agreement with the Portfolios, and
 
(iii) Eligible Institutions providing shareholder services under various

HISTORICAL PERFORMANCE OF COMPARABLE DISCRETIONARY ACCOUNTS -- VALUE EQUITY
FUND. The following table sets forth (i) the composite total return for the
period January 1, 1995 (commencement of operations of the relevant accounts)
through December 31, 1997 and the year ended December 31, 1997 for all
discretionary accounts described below that have been managed for at least one
full quarter by UBSAM, (ii) the average annual total return for the Value Equity
Fund for the period April 2, 1996 (commencement of operations) through December
31, 1996 and the year ended December 31, 1997, and (iii) the annual total return
during the same periods for the S&P 500 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 Value Equity
Portfolio. While the Value Equity Portfolio will be managed by the Adviser, the
management of the Value Equity Portfolio will be substantially the same as by
UBSAM and will be carried out by personnel who performed these services for the
discretionary accounts at UBSAM, who will be employed by the Adviser for this
purpose. The composite total return for such accounts has been adjusted to
deduct all of the Value Equity Fund's annual total operating expenses of 1.00%
of average daily net assets as set forth in the Expense Table above. The Fund's
historical average annual total return is computed after deducting the Fund's
allowable total operating expenses of 1.00% of average daily net assets. No such
accounts were managed by UBSAM or the Adviser prior to 1995. 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 Value
Equity 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 Value Equity
Portfolio and should not be viewed as a prediction of future performance of the
Value Equity Portfolio. The S&P 500 Index is an unmanaged index that includes
500 U.S. stocks and is a common measure of the performance of the U.S. stock
market. The total returns of the S&P 500 Index do not include management fees or
commissions.

HISTORICAL PERFORMANCE OF COMPARABLE DISCRETIONARY ACCOUNTS -- INTERNATIONAL

total returns for the one, three and five year periods ended December 31, 1997
and the period from April 1, 1987 (commencement of operations of the relevant
accounts) through December 31, 1997 for all discretionary accounts described
below that have been managed for at least one full quarter by UBSII, (ii) the
average annual return for the International Equity Fund for the period April 2,
1996 (commencement of operations) through December 31, 1996 and the year ended
December 31, 1997, and (iii) the average annual total return during the same
periods for the Morgan Stanley Capital International Eupope, Australia, Far East
Index (the 'EAFE 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 International Equity Portfolio. The
composite total returns for such accounts have been adjusted to deduct all of
the International Equity Fund's allowable total operating expenses of 1.40% of
average daily net assets. The composite total returns are time-weighted and are
equally weighted for periods prior to 1994, after which they are size-weighted,
and they reflect 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 International Equity Portfolio that, if applied to the accounts, may have
adversely affected their performance results. UBSII believes that the
restatement of total returns prior to 1994 would not result in any material
changes in the total returns

all discretionary accounts described below that have been managed for at least
one full quarter by UBSAM, (ii) the average annual total return for the Large
Cap Growth Fund for the period October 14, 1997 (commencement of operations)

HISTORICAL PERFORMANCE OF COMPARABLE DISCRETIONARY ACCOUNTS -- SMALL CAP FUND.
The following table sets forth (i) the composite total return for the one,
three, five and ten year periods ended December 31, 1997 for all discretionary
accounts described below that have been managed for at least one full quarter by
UBSAM, (ii) the average annual total return for the Small Cap Fund for the
period September 30, 1997 (commencement of operations) through December 31, 1997
and (iii) the average

 
                                      -11-
 <PAGE>
<PAGE>
annual total returns during the same periods for the Russell 2000 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 Small Cap Portfolio. The composite total return for such accounts
has been adjusted to deduct all of the Small Cap 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 Small Cap 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 Small Cap Portfolio and should not be viewed as a prediction
of future performance of the Small Cap Portfolio. The Russell 2000 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 Russell 2000 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 Funds seek to achieve their investment objectives by
investing all of their investable assets in their respective Portfolios. The
Portfolios are separate investment companies with the same investment objective
as their respective Fund. The investment objective of a Fund and a Portfolio may
be changed only with the approval of the holders of a majority of the
outstanding voting securities of such Fund or a majority of the investors in
such Portfolio, respectively, after 30 days' prior notice.
 

In addition to selling an interest in a Portfolio to a Fund, each Portfolio may
sell interests in such Portfolio to other mutual funds or institutional
investors. Such investors will invest in the Portfolio on the same terms and
conditions as a Fund and will pay a proportionate share of the Portfolio's
expenses. However, other entities investing in the Portfolios may sell shares of
their own fund using a different pricing structure than a Fund's. Such different
pricing structures may result in differences in returns experienced by investors
in other funds that invest in the Portfolios. Such differences in returns are
not uncommon and are present in other mutual fund structures. Information
concerning other holders of interests in the Portfolios is available from
Investors Bank at (888) UBS-FUND (888-827-3863).

 
Each Fund may withdraw its investment in its 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 a Portfolio's investment objective, policies or restrictions,
or a failure by a Fund's shareholders to approve a change in a Portfolio's
investment objective or restrictions, may require a 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 a
Portfolio to a Fund. In no event, however,
 
                                      -12-
 <PAGE>
<PAGE>
will securities which are not readily marketable exceed 15% of the total value
of such in-kind distribution. Such a distribution may result in a Fund having a
less diversified portfolio of investments or adversely affect a Fund's
liquidity, and a 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 Portfolios may be materially affected by the
actions of larger funds investing in the Portfolios. For example, if a large
fund withdraws from a Portfolio, the remaining funds may subsequently experience
higher pro rata operating expenses, thereby lowering returns. Additionally,
because a 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 a Portfolio could have effective voting control of its operations.
Except as permitted by the SEC, whenever a Fund is requested to vote on matters
pertaining to a 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 a 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 Fund shareholders who do, in fact, vote.
 

For more information about each Portfolio's investment objective, policies and
restrictions, see 'Investment Objectives and Policies,' 'Additional Investment
Information and Risk Factors' and 'Investment Restrictions.' For more
information about each Portfolio's management and expenses, see 'Management.'
For more information about changing the investment objective, policies and
restrictions of the Funds or the Portfolios, see 'Investment Restrictions.'

 
INVESTMENT OBJECTIVES AND POLICIES
 
The investment objectives of the Funds and the Portfolios are described below,
together with the policies each employs to seek to achieve its objective.
Additional information about the investment policies of the Funds and the
Portfolios appears in the SAI under 'Investment Objectives and Policies.' Each
Fund seeks to achieve its investment objective by investing all of its
investable assets in its respective Portfolio, which has the same investment
objective as the Fund. There can be no assurance that the investment objectives
of the Funds or the Portfolios will be achieved.
 
UBS VALUE EQUITY FUND AND VALUE EQUITY PORTFOLIO
 
The Value Equity Portfolio's objective is to provide long-term capital
appreciation and the potential for a high level of current income with lower
investment risk and volatility than is normally available from common stock
funds. In order to accomplish this, the Adviser intends to invest in undervalued
stocks having above market dividend yields with emphasis on those securities
which have the potential for long-term earnings growth and increasing dividend
payments. The average dividend yield of the Value Equity Portfolio's common
stocks is expected to be at least 50% greater than that of the S&P 500 Index. It
is also the objective of the Value Equity Portfolio that the Value Equity
Portfolio's investments have less price volatility than the S&P 500 Index.
 
Under normal circumstances, the Value Equity Portfolio will invest at least 80%
of its assets in income-producing equity securities of domestic issuers,
including dividend-paying common stocks and securities which are convertible
into common stocks. The Value Equity Portfolio intends to invest in securities
that generate relatively high levels of dividend income and have the potential
for capital appreciation. These generally include common stocks of established,
high-quality U.S. corporations. In addition, the Value Equity Portfolio will
seek to diversify its investment over a carefully selected list of securities in
order to moderate the risks inherent in equity investments.
 
The Value Equity Portfolio will invest in an equity security following a
fundamental analysis of the issuing company. An important part of this analysis
will be the examination of the company's ability to maintain its dividend. The
Adviser believes that dividend income has proven to be an important component of
total return. For example, during the ten-year period ended December 31, 1997,
reinvested
 
                                      -13-
 <PAGE>
<PAGE>
dividend income accounted for approximately 25% of the total return of the S&P
500 Index. Also, the Adviser believes that dividend income tends to be a more
stable source of total return than capital appreciation. While the price of a
company's common stock can be significantly affected by market fluctuations and
other short-term factors, its dividend level usually has greater stability. For
this reason, securities that pay a high level of dividend income tend to be less
volatile in price than comparable securities that pay a lower level of dividend
income.
 
Although the Value Equity Portfolio intends to invest primarily in equity
securities, 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; commercial paper, bank certificates of deposit and bankers'
acceptances; and repurchase agreements collateralized by these securities. The
Value Equity Portfolio may also purchase nonpublicly offered debt securities.
See 'Additional Investment Information and Risk Factors -- Illiquid Investments;
Privately Placed and Other Unregistered Securities.'
 
The Value Equity 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 Value Equity Portfolio intends to manage its securities actively in pursuit
of its investment objective. Although it generally seeks to invest for the
long-term, the Value Equity Portfolio retains the right to sell securities
irrespective of how long they have been held. See 'Portfolio Transactions' in
the SAI. To the extent the Value Equity Portfolio engages in short-term trading,
it may incur increased transaction costs. For the period April 2, 1996
(commencement of operations) to December 31, 1996 and for the year ended
December 31, 1997, the portfolio turnover rate for the Value Equity Portfolio
was 19% and 47%, respectively.

 

Under normal circumstances, the Adviser intends to invest at least 80% of the
Value Equity Portfolio's assets in the equity securities of domestic issuers.
These investments will consist of common stocks and other securities with equity
characteristics such as preferred stock, warrants, rights and convertible
securities. The Value Equity Portfolio's primary equity investments are the
common stocks of established domestic companies. The common stock in which the
Value Equity Portfolio may invest includes the common stock of any class or
series or any similar equity interest such as trust or limited partnership
interests. The Value Equity Portfolio invests in domestic securities listed on
domestic securities exchanges and securities traded in domestic over-the-counter
markets, and may invest in certain restricted or unlisted securities. See
'Additional Investment Information and Risk Factors.'

 
UBS INTERNATIONAL EQUITY FUND AND INTERNATIONAL EQUITY PORTFOLIO
 
The Adviser is responsible for supervising the management of the International
Equity Portfolio's investments. Consistent with these duties, the Adviser has
entered into a Sub-Advisory Agreement with UBSII, whereby UBSII is primarily
responsible for the day-to-day investment decisions for the International Equity
Portfolio. The Adviser is solely responsible for paying UBSII for these
services. UBSII is an affiliate of the Adviser.
 
The International Equity Portfolio's investment objective is to provide a high
total return from a portfolio of equity securities of foreign corporations.
Total return will consist of realized and unrealized capital gains and losses
plus net income. The International Equity Fund is designed for investors with a
long-term investment horizon who want to diversify their investments by adding
international equities and take advantage of investment opportunities outside
the United States.
 
The International Equity Portfolio seeks to achieve its investment objective by
investing in companies that UBSII believes are fundamentally sound and that are
typically selling at below market valuations and that UBSII believes will grow
at above-market rates. The emphasis on value leads to investments in companies
with relatively low price/earnings and price/book value ratios and high yields.
 
                                      -14-
 <PAGE>
<PAGE>
UBSII actively manages currency exposure, in conjunction with country and stock
allocations, in an attempt to protect the International Equity Portfolio's
market value. Through the use of forward foreign currency exchange contracts,
futures contracts and options on currencies, UBSII will adjust the International
Equity Portfolio's foreign currency weightings to reduce its exposure to
currencies deemed unattractive as market conditions warrant, based on
fundamental research, technical factors and the judgment of UBSII's experienced
currency managers. For more information on foreign currency exchange
transactions, see 'Additional Investment Information and Risk Factors.'
 
The International Equity Portfolio intends to manage its securities actively in
pursuit of its investment objective. The International Equity Portfolio does not
expect to trade in securities for short-term profits; however, when
circumstances warrant, securities may be sold without regard to the length of
time held. It is anticipated that the annual portfolio turnover rate of the
International Equity Portfolio will be less than 100%. See 'Portfolio
Transactions' in the SAI. To the extent the International Equity Portfolio
engages in short-term trading, it may incur increased transaction costs. For the
period April 2, 1996 (commencement of operations) to December 31, 1996 and for
the year ended December 31, 1997, the portfolio turnover rate for the
International Equity Portfolio was 42% and 26%, respectively.
 
EQUITY INVESTMENTS. Under normal circumstances, UBSII intends to keep at least
65% of the value of the International Equity Portfolio's total assets in equity
securities of foreign issuers, consisting of common stocks and other securities
with equity characteristics such as preferred stock, warrants, rights and
convertible securities.
 
The International Equity Portfolio's primary equity investments are the common
stock of established companies based in developed countries outside the United
States. The International Equity Portfolio will invest in companies based in at
least five foreign countries. The common stock in which the International Equity
Portfolio may invest includes the common stock of any class or series or any
similar equity interest such as trust or limited partnership interests. The
International Equity Portfolio may also invest in securities of issuers located
in developing countries. See 'Additional Investment Information and Risk
Factors -- Risk Factors of Foreign Securities.' The International Equity
Portfolio will invest in securities listed on foreign or domestic securities
exchanges and securities traded in foreign or domestic over-the-counter markets,
and may invest in certain restricted or unlisted securities.
 
The International Equity Portfolio may also invest in money market instruments
denominated in U.S. dollars and other currencies, purchase securities on a
when-issued or delayed delivery basis, enter into repurchase and reverse
repurchase agreements, loan its portfolio securities, purchase certain privately
placed securities, enter into forward contracts on foreign currencies, purchase
options on currencies 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.'
 
UBS LARGE CAP GROWTH FUND AND LARGE CAP GROWTH PORTFOLIO
 

The Adviser is responsible for supervising the management of the Large Cap
Growth Portfolio's investments. Consistent with these duties, the Adviser has
entered into a Sub-Advisory Agreement with UBSAM, whereby UBSAM is primarily
responsible for the day-to-day investment decisions for the Large Cap Growth
Portfolio. The Adviser is solely responsible for paying UBSAM for these
services. UBSAM is an affiliate of the Adviser.

 
The Large Cap Growth Portfolio's objective is to provide long-term capital
appreciation. In order to accomplish this, the Large Cap Growth 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 Large Cap Growth Portfolio defines 'large capital'
companies as companies whose market capitalizations at the time of acquisition
by the Large Cap Growth Portfolio are within the market capitalization range of
those stocks listed on the S&P 500 Index. Additionally, the Large Cap Growth
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 UBSAM's judgment, the
prospects for
 
                                      -15-
 <PAGE>
<PAGE>
above-average earnings and cash flow growth or meaningful increases in
underlying asset values over time.
 
The Large Cap Growth Portfolio may also invest up to 20% of its assets in
foreign securities, including American Depository Receipts ('ADRs'), which UBSAM
believes meet the Large Cap Growth 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 Large Cap Growth Portfolio will invest at least
65% of its assets in large capital growth companies. The Large Cap Growth
Portfolio will invest in companies believed by UBSAM to represent above average
growth opportunities. UBSAM will select individual securities for investment by
screening for above average earnings growth expectations and reasonable
valuations (price relative to earnings and cash flow). Growth company securities
may have above average price volatility. The Large Cap Growth 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 Large Cap Growth 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 Large Cap
Growth Portfolio or UBSAM have adopted a defensive investment posture, the Large
Cap Growth Portfolio may invest without limit in these securities. The Large Cap
Growth Portfolio may also purchase nonpublicly offered debt securities. See
'Additional Investment Information and Risk Factors -- Illiquid Investments;
Privately Placed and Other Unregistered Securities.'
 
The Large Cap Growth Portfolio may also utilize equity futures contracts and
options to a limited extent. Specifically, the Large Cap Growth Portfolio may
enter into futures contracts and options provided that such positions are
established for hedging purposes only. See 'Additional Investment Information
and Risk Factors -- Futures Contracts' and ' -- Options.'
 
The Large Cap Growth Portfolio may also sell securities short to a limited
extent and for hedging purposes only. See 'Additional Investment Information and
Risk Factors -- Short Sales.' The Large Cap Growth Portfolio may also invest in
'special situations.' See 'Additional Investment Information and Risk
Factors -- Special Situations.'
 

The Large Cap Growth Portfolio intends to manage its securities actively in
pursuit of its investment objective. Although it generally seeks to invest for
the long-term, the Large Cap Growth 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 Large Cap Growth Portfolio will not exceed
100%. To the extent the Large Cap Growth Portfolio engages in short-term
trading, it may incur increased transaction costs. For the period October 14,
1997 (commencement of operations) through December 31, 1997, the portfolio
turnover rate for the Large Cap Growth Portfolio was 6%.

 
UBS SMALL CAP FUND AND SMALL CAP PORTFOLIO
 
The Adviser is responsible for supervising the management of the Small Cap
Portfolio's investments. Consistent with these duties, the Adviser has entered
into a Sub-Advisory Agreement with UBSAM, whereby UBSAM is primarily responsible
for the day-to-day investment decisions for the Small Cap Portfolio. The Adviser
is solely responsible for paying UBSAM for these services. UBSAM is an affiliate
of the Adviser.
 
The Small Cap Portfolio's objective is to provide long-term capital
appreciation. In order to accomplish this, the Small Cap Portfolio intends to
invest primarily in a diversified portfolio of common stocks,
 
                                      -16-
 <PAGE>
<PAGE>
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 Small Cap Portfolio defines 'small capital' companies as
companies whose market capitalization at the time of acquisition by the Small
Cap Portfolio is 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 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 Small Cap Portfolio may also invest up to 20% of its assets in foreign
securities, including ADRs, which UBSAM believes meet the Small Cap 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 Small Cap Portfolio will invest at least 65% of
its assets in small capital growth companies. The Small Cap 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 Small Cap Portfolio will invest, on an individual security basis, in
companies believed by UBSAM to represent above average growth opportunities.
UBSAM 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 Small Cap 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

extent the Small Cap Portfolio engages in short-term trading, it may incur
increased transaction costs. For the period September 30, 1997

(commencement of operations) through December 31, 1997, the portfolio turnover
rate for the Small Cap Portfolio was 3%.

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 Small Cap Portfolio'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.
 
SPECIAL SITUATIONS. From time to time, the Large Cap Growth Portfolio and Small
Cap Portfolio may invest in special situations. A special situation arises when
UBSAM, as 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 UBSAM anticipates that the price of a security
will decline, it may sell the security short and borrow the same security from a
broker or other institution to complete the sale. The Small Cap and Large Cap
Growth Portfolios will only enter into short sales for hedging purposes. The
Small Cap and Large Cap Growth Portfolios 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 Small Cap or Large
Cap Growth Portfolio must replace the borrowed security. All short sales will be
fully collateralized and the Small Cap and Large Cap Growth Portfolios will not
sell securities short if immediately after and as a result of the short sale,
the value of all securities sold short by either of the Small Cap or Large Cap
Growth Portfolio exceeds 25% of its total assets. The Small Cap and Large Cap
Growth Portfolios will also limit short sales of any one issuer's securities to
2% of their total assets and to 2% of any one class of the issuer's securities.

 
CONVERTIBLE SECURITIES. Each Portfolio may invest in convertible securities. The
convertible securities in which the Portfolios 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. Each 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
Portfolios 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, a 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, a Portfolio will rely on the other party to consummate the
transaction; if the other party fails to do so, a Portfolio may be
disadvantaged. It is the current policy of the Portfolios not to enter into
when-issued commitments exceeding in the aggregate 15% of the market value of
such Portfolio's total assets less liabilities (excluding the obligations
created by these commitments).

<PAGE>
MONEY MARKET INSTRUMENTS. Each of the Portfolios is permitted to invest in money
market instruments although they intend to stay invested in equity securities to
the extent practical in light of their objectives and long-term investment
perspectives. The Portfolios may make money market investments pending other
investments or settlements, for liquidity purposes or in adverse market
conditions. Such money market investments may include obligations of the U.S.
Government and its agencies and instrumentalities, commercial paper, bank
obligations, money market mutual funds and repurchase agreements. The
International Equity Portfolio may also invest in short-term obligations of
sovereign foreign governments, their agencies, instrumentalities, and political
subdivisions. For more detailed information about these money market
investments, see 'Investment Objectives and Policies' in the SAI.
 
REPURCHASE AGREEMENTS. Each 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, a 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 a Portfolio to the seller. A 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, a Portfolio might incur a loss. If bankruptcy proceedings are
commenced with respect to the seller, a Portfolio's realization upon the
disposition of collateral may be delayed or limited. Investments in repurchase
agreements maturing in more than seven days may be considered illiquid and are
limited. See 'Illiquid Investments; Privately Placed and Other Unregistered
Securities' below.
 
REVERSE REPURCHASE AGREEMENTS. Each Portfolio is also permitted to enter into
reverse repurchase agreements. In a reverse repurchase agreement, a 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 a Portfolio to be
magnified. For more information, including limitations on the use of reverse
repurchase agreements, see 'Investment Objectives and Policies' in the SAI.
 
ILLIQUID INVESTMENTS; PRIVATELY PLACED AND OTHER UNREGISTERED SECURITIES. Each
Portfolio may not acquire any illiquid securities if, as a result thereof, more
than 15% of the market value of such Portfolio's net assets would be in illiquid
investments or investments that are not readily marketable. In addition, each
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 (the 'Securities Act'). Subject to those non-
fundamental policy limitations, each 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 a
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 a 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.
 
Each 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.
 
SECURITIES LENDING. Subject to applicable investment restrictions, a Portfolio
may lend its securities. A 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 a Portfolio in the normal
 
                                      -19-
 <PAGE>
<PAGE>
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 finders' and custodial fees in
connection with a loan. In addition, the Portfolios will consider all the 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 of the Company, the Trust, a Portfolio, or the Adviser,
Administrator or Distributor, unless otherwise permitted by applicable law.
 
RISK FACTORS OF FOREIGN SECURITIES. Investments in non-U.S. issuers involve
certain risks and considerations not typically associated with investments in
U.S. issuers. These risks include greater price volatility, reduced liquidity
and the significantly smaller market capitalization of most non-U.S. securities
markets, more substantial government involvement in the economy, higher rates of
inflation, greater social, economic and political uncertainty and the risk of
nationalization or expropriation of assets and risk of war.
 
The International Equity Portfolio will invest primarily in foreign securities.
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 International Equity 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 International Equity 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
International Equity Portfolio must be made in compliance with U.S. and foreign
currency restrictions and tax laws restricting the amounts and types of such
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 International Equity
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.
 
Although the International Equity Portfolio invests primarily in securities of
established issuers based in developed foreign countries, it may also invest in
securities of issuers in developing market countries. Investments in securities
of issuers in developing market countries may involve a high degree of risk and
many may be considered speculative. These investments carry all of the risks of
investing in securities of foreign issuers outlined in this section to a
heightened degree. These heightened risks include: (i) greater risks of
expropriation, confiscatory taxation, nationalization, and less social,
political and economic stability; (ii) the small current size of the markets for
securities of emerging market issuers and the currently low or non-existent
volume of trading, resulting in limited liquidity and in price volatility; (iii)
certain national policies that may restrict the International Equity Portfolio's
investment opportunities
 
                                      -20-
 <PAGE>
<PAGE>
including restrictions on investing in issuers or industries deemed sensitive to
relevant national interests; and (iv) the absence of developed legal structures
governing private or foreign investment and private property.
 
Each Portfolio (except the Value Equity Portfolio) may invest in securities of
foreign issuers directly or in the form of 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 International Equity
Portfolio will and the Small Cap Portfolio and the Large Cap Growth Portfolio
may buy and sell securities and will receive interest and dividends in
currencies other than the U.S. dollar, the International Equity, Small Cap and
Large Cap Growth Portfolios may, from time to time, enter into foreign currency
exchange transactions. The International Equity, Small Cap, and Large Cap Growth
Portfolios 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 such 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 International Equity, Small Cap, and Large Cap Growth
Portfolios 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 such 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 International Equity, Small Cap and Large Cap Growth Portfolios 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 International Equity, Small Cap and Large Cap Growth
Portfolios 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 such Portfolio for currency or
futures options increase the Portfolio's transaction costs. Similarly, the cost
of the Portfolio's spot currency
 
                                      -21-
 <PAGE>
<PAGE>
exchange transactions is generally the difference between the bid and offer spot
rate of the currency being purchased or sold. Moreover, forward contracts that
convert one foreign currency into another foreign currency will cause the
Portfolio to assume the risk of fluctuations in the value of the currency
purchased vis-a-vis the hedged currency and the U.S. dollar. 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.
 
FUTURES AND OPTIONS TRANSACTIONS. Each Portfolio is permitted to enter into the
futures and options transactions described below. These instruments are commonly
known as derivatives.
 
The Portfolios 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 Portfolios 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 Portfolios may use these techniques to manage their exposure to changing
interest rates and/or security prices. Some options and futures strategies,
including selling futures contracts and buying puts, tend to hedge a 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 a 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 Portfolios 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 a Portfolio's overall strategy in a manner deemed
appropriate to the Adviser or Sub-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.
 
A 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 a Portfolio's return. While a 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 or Sub-Adviser applies a strategy at an inappropriate time or judges
market conditions or trends incorrectly, such strategies may lower a Portfolio's
return. Certain strategies limit a Portfolio's opportunity to realize gains as
well as limiting its exposure to losses. A 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, a 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 Portfolios 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.
 
The Commodity Exchange Act prohibits U.S. persons, such as the Portfolios, from
buying or selling certain foreign futures contracts or options on such
contracts. Accordingly, the International Equity Portfolio will not engage in
foreign futures or options transactions unless the contracts in question may
lawfully be purchased and sold by U.S. persons in accordance with applicable
Commodity Futures Trading Commission ('CFTC') regulations or CFTC staff
advisories, interpretations and no action letters.
 
                                      -22-
 <PAGE>
<PAGE>
In addition, in order to assure that the Portfolios will not be considered a
'commodity pool' for purposes of CFTC rules, the Portfolios 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 such 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, a 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, a 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. A Portfolio may
terminate its position in a put option it has purchased by allowing it to expire
or by exercising the option. A 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, a Portfolio will lose the entire premium it
paid. If a Portfolio exercises a put option on a security, it will sell the
instrument underlying the option at the strike price. If a 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 a 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, a 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. A 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 a
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 a 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.
 
                                      -23-
 <PAGE>
<PAGE>
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. Each 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 a 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. A
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
a 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 a Portfolio may
not be able to close out an option position that it has previously entered into.
When a Portfolio purchases an OTC option, it will be relying on its counterparty
to perform its obligations, and a Portfolio may incur additional losses if the
counterparty is unable to perform.
 
FUTURES CONTRACTS
 
When a 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 a
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 a 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 a 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 a
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 a 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 a 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 a Portfolio's current or
anticipated investments. The Portfolios 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 such Portfolio's other investments. A Portfolio may
also enter into transactions in futures contracts and options for specific
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 a Portfolio buys or sells a futures contract it will be
required to deposit 'initial margin' 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. A 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 a
Portfolio to close out its futures positions. Until it closes out a futures
position, a Portfolio will be obligated to continue to pay variation margin.
Initial and variation margin payments do not constitute purchasing on margin for
purposes of a Portfolio's investment restrictions. In the event of the
bankruptcy
 
                                      -24-
 <PAGE>
<PAGE>
of an FCM that holds margin on behalf of a Portfolio, a 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. Each 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 objectives of each Fund and its respective 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
1940 Act), of such Fund or such Portfolio, respectively. Each Fund has the same
investment restrictions as its respective Portfolio, except that a Fund may
invest all of its investable assets in another open-end investment company with
the same investment objective and restrictions (such as its respective
Portfolio). References below to a Portfolio's investment restrictions also
include the Fund's investment restrictions.
 
As a diversified investment company, 75% of the total assets of each Portfolio

A Portfolio may not: (i) purchase the securities or other obligations of issuers

MANAGEMENT
 
DIRECTORS AND TRUSTEES. Pursuant to the Trust's Declaration of Trust, the
Trustees establish each Portfolio's general policies, are responsible for the
overall management of the Trust, and review the actions of the Adviser, UBSAM,
UBS II, the Administrator and other service providers. Similarly, the Directors
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 each Board and the officers of the Trust and the Company
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 Trust and the Company are also employees of Investors Bank or
its affiliates.
 
ADVISER, SUB-ADVISERS AND FUNDS SERVICES AGENT. The Company has not retained the
services of an investment adviser with respect to the Funds because the Funds
seek to achieve their investment objective by investing all of their investable
assets in their respective Portfolios. Each Portfolio has retained the
 
                                      -25-

<PAGE>
services of the Branch as investment adviser. The International Equity Portfolio
has retained the services of UBSII as investment sub-adviser and the Large Cap
Growth and Small Cap Portfolios have each retained the services of UBSAM as
investment sub-adviser. 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 United States. UBSII, with principal offices at Triton Court, 14 Finsbury
Square, London, England, EC2A 1PD, is a corporation organized under the laws of
the United Kingdom.
 

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 December 31, 1997, the Bank (including its consolidated
subsidiaries) had total assets of $395.1 billion (unaudited) and shareholders'
equity of $14.4 billion (unaudited).

 

On December 8, 1997, the Bank and Swiss Bank Corporation ('Swiss Bank')
announced their intention to merge (the 'Merger Transaction') the Bank with
Swiss Bank to form a new company expected to be called UBS. In February, 1998
the shareholders of UBS and Swiss Bank overwhelmingly approved the Merger
Transaction. The Merger Transaction's completion is still subject to a number of
conditions, including the receipt of regulatory approvals.

 
The Adviser, UBSAM and UBSII each provide investment advice and portfolio
management to the respective Portfolios. Subject to the supervision of the
Trustees and the Adviser, UBSII makes the International Equity Portfolio's
day-to-day investment decisions, arranges for the execution of portfolio
transactions and generally manages the International Equity Portfolio's
investments and operations. Subject to the supervision of the Trustees and the
Adviser, UBSAM makes the Large Cap Growth and Small Cap Portfolios' day-to-day
investment decisions, arranges for the execution of portfolio transactions and
generally manages the investments and operations for the Large Cap Growth and

SAI.
 
In addition to the above-listed investment advisory services, the Branch also
provides the Funds and the Portfolios 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 Funds and Portfolios 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 Funds and providing any resultant expense
reimbursement to the Funds.
 
The Branch provides its administrative services to each 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 Funds pursuant to the terms of the Funds
Services Agreement.
 

Under the Trust's Investment Advisory Agreement, the Value Equity Portfolio,
International Equity Portfolio, Large Cap Growth Portfolio and Small Cap
Portfolio pay the Adviser a fee, calculated daily and payable monthly, equal, on
an annual basis, to 0.60%, 0.85%, 0.60%, and 0.60% of the respective Portfolio's

share of its Portfolio's expenses) exceed, respectively, on an annual basis,
1.00%, 1.40%, 1.00%, and 1.20% of the respective Fund's average daily net
assets. The Adviser may modify or discontinue this fee waiver and expense
limitation at any time in the future with 30 days' prior notice to a Fund. See

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 Company also reserves the right to determine the purchase
orders that it will accept and reserves the right to cease offering its shares
for a
 
                                      -28-

<PAGE>
period of time. The shares of a Fund may be purchased only in those states where
they may be lawfully sold.
 
The minimum initial investment in a 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 a Fund for all investors is $5,000. The
minimum initial investment for employees of the Bank or its affiliates is
$5,000. The minimum subsequent investment is $1,000. These minimum investment
requirements may be waived at a Fund's discretion.
 
No share certificates will be issued.
 
PURCHASE PRICE AND SETTLEMENT. Fund shares 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. Each 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 SAI.
 
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 a 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 a 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. Shareholders 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 marked on the check 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 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 a 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. The Funds may
suspend redemptions or postpone payments when the NYSE is closed or when trading
is restricted for any reason or under emergency circumstances as determined by
the SEC.
 

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 a Fund.
Such shareholders risk possible loss of principal and income in the event of a
telephone redemption not authorized by them. The Funds 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 a Fund or the
Transfer Agent to employ such procedures may cause a 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 a 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.
 
                                      -30-
 <PAGE>
<PAGE>
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, a Fund must have received the shareholder's taxpayer
identification number and address. As discussed under 'Taxes' below, a 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 Company's other 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 Funds reserve the right to discontinue, alter or limit the
exchange privilege at any time.
 
RETIREMENT PLANS
 
The Funds have 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 Funds 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 Funds do 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 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 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 (888-827-3863).

DIVIDENDS AND DISTRIBUTIONS
 
Dividends consisting of substantially all of a Fund's net investment income, if
any, are declared and paid annually. The Funds 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 such Fund.
 
Substantially all of a 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 a 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 a 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 Funds reserve the right to discontinue, alter or limit the
automatic reinvestment privilege at any time.
 
NET ASSET VALUE
 
A Fund's net asset value per share equals the value of a Fund's total assets
(i.e., the value of its investment in its 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 Funds and the Portfolios, 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 a Portfolio's assets and liabilities.
 
Each 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
Funds 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, Dr. Martin Luther King, Jr. 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 expect to close for purchases
and redemptions at the same time.

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 nine series: The UBS Bond Fund Series; The UBS Tax Exempt Bond Fund Series;
The UBS High Yield Bond Fund Series; The UBS Real Estate Fund Series; The UBS
International Equity Fund Series; The UBS Institutional International Equity
Fund Series; The UBS Value Equity Fund Series; The UBS Small Cap 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 Value
Equity Fund Series, The UBS International Equity Fund Series, The UBS Small Cap
Fund Series and The UBS Large Cap Growth Fund Series are offered through this
Prospectus.
 
Shareholders of a 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
 
The 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: the Value Equity Portfolio, International Equity
Portfolio, Small Cap Portfolio, Large Cap Growth Portfolio, Real Estate
Portfolio, Bond Portfolio and High Yield Bond Portfolio.
 
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 a
Portfolio, but that only the Trust property shall be liable. The Declaration of
Trust provides that a Fund and other entities investing in a 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 a 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 Funds nor their shareholders
will be adversely affected by reason of a Fund's investment in a Portfolio.
 
TAXES
 
Each of the Funds intends to annually qualify and elect to be treated as RICs
under Subchapter M of the 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. Each Portfolio intends to qualify as a partnership for federal
income tax purposes. As such, the Portfolios generally should not be subject to
tax. The status of each Fund as a RIC is dependent on, among other things, each
respective Portfolio's continued qualification as a partnership for federal
income tax purposes.
 
Distributions of net investment income and 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. Distributions of net gains from certain foreign
currency transactions are taxable as ordinary income to shareholders of the
International Equity Fund 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 a 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 such 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 a
year, otherwise as short-term capital gain or loss. However, any loss realized
by a shareholder upon the redemption or exchange of shares in a 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 a 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 such
Fund.

 
The Funds 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
 
                                      -33-
 <PAGE>
<PAGE>
taxable to shareholders in the calendar year in which it was earned by such
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.
 
The International Equity Portfolio is subject to foreign withholding taxes with
respect to income received from sources within certain foreign countries. So
long as more than 50% of the value of the International Equity Portfolio's total
assets at the close of any taxable year consists of stock or securities of
foreign corporations, the International Equity Fund may elect to treat its
proportionate share of foreign income taxes paid by the International Equity
Portfolio as paid directly by the International Equity Fund's shareholders. The
International Equity Fund will make such an election only if it deems it to be
in the best interests of its shareholders and will notify shareholders in
writing each year that it makes the election of the amount of foreign income
taxes, if any, to be treated as paid by the shareholders. If the International
Equity Fund makes the election, each shareholder will be required to include in
income its proportionate share of the amount of foreign income taxes paid by the
International Equity Portfolio and will be entitled to claim either a credit
(which is subject to certain limitations), or, if the shareholder itemizes
deductions, a deduction for its share of the foreign income taxes in computing
its federal income tax liability. No deduction will be permitted to individuals
in computing their alternative minimum tax liability.
 
If the International Equity Portfolio or the International Equity Fund purchases
shares in certain foreign investment entities, referred to as 'passive foreign
investment companies,' the International Equity Fund may be subject to U.S.
Federal income tax, and an additional charge in the nature of interest, on a
portion of any 'excess distribution' from such company or gain from the
disposition of such shares, even if the distribution or gain is paid by the
International Equity Fund as a dividend to its shareholders. If the
International Equity Fund were able and elected to treat a passive foreign
investment company as a 'qualified electing fund,' in lieu of the treatment
described above, the International Equity Fund would be required each year to
include in income, and distribute to shareholders in accordance with the
distribution requirement set forth above, the International Equity Fund's pro
rata share of the ordinary earnings and net capital gains of the company,
whether or not distributed to the International Equity Fund.
 
Distributions of net investment income or net long-term capital gains will have
the effect of reducing the net asset value of a 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, a 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 Funds will send their 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 Funds may make historical performance information available and may compare
its performance to other investments or relevant indices, including data from
Morgan Stanley Indices, Lipper Analytical Services, Inc., Micropal Inc.,
Morningstar Inc., Ibbotson Associates, S&P 500 Index, the Dow Jones Average, the
Frank Russell Indices, the MSCI EAFE Index, the Financial Times World Stock
Index and other industry publications.

 
The Funds may advertise 'total return.' The total return shows what an
investment in a 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.

This Prospectus pertains to the UBS Bond Fund (the 'Bond Fund') and the UBS High
Yield Bond Fund (the 'High Yield Bond Fund,' each a 'Fund,' collectively, the
'Funds').
 
The Funds are diversified, no-load mutual funds for which there are no sales
charges or exchange or redemption fees. The Funds are two of several series of
UBS Private Investor Funds, Inc. (the 'Company'), an open-end management
investment company organized as a corporation under Maryland law.

INVESTING ALL OF ITS INVESTABLE ASSETS IN UBS BOND PORTFOLIO (THE 'BOND
PORTFOLIO'), AND THE HIGH YIELD BOND FUND SEEKS TO ACHIEVE ITS INVESTMENT
OBJECTIVE BY INVESTING ALL OF ITS INVESTABLE ASSETS IN UBS HIGH YIELD BOND
PORTFOLIO (THE 'HIGH YIELD BOND PORTFOLIO,' EACH A 'PORTFOLIO,' COLLECTIVELY,
THE 'PORTFOLIOS'). THE PORTFOLIOS ARE SERIES OF UBS INVESTOR PORTFOLIOS TRUST
(THE 'TRUST'), AN OPEN-END MANAGEMENT INVESTMENT COMPANY. THE PORTFOLIOS HAVE
THE SAME INVESTMENT OBJECTIVES AS THEIR RESPECTIVE FUNDS. THE FUNDS EMPLOY A
TWO-TIER MASTER-FEEDER INVESTMENT FUND STRUCTURE THAT IS MORE FULLY DESCRIBED
UNDER THE SECTION CAPTIONED 'MASTER-FEEDER STRUCTURE.'
 
The Portfolios are advised by the New York Branch (the 'Branch' or the

Portfolio has entered into a sub-advisory agreement with UBS Asset Management
(New York) Inc. ('UBSAM', the 'Sub-Adviser' and, together with the Adviser, the

INVESTORS FOR WHOM THE FUND IS DESIGNED
 

GENERAL

 
This Prospectus describes each Fund's investment objective and policies,
management and operations to enable investors to decide if either Fund suits
their investment needs. Because the investment characteristics and experience of
the Funds will correspond directly with those of the Portfolios, the discussion
in this section of the Prospectus focuses on the investments and investment
policies of the Portfolios. There is no assurance that either Fund or its
corresponding Portfolio will achieve its stated objective.
 
Each Portfolio is a series of the Trust, an open-end management investment
company. Each Portfolio has the same investment objective as its respective
Fund. The net asset values of shares of each Fund fluctuate with changes in the
value of the investments in such Fund's respective Portfolio.
 

The minimum initial investment in either 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 for all investors is $5,000. These
minimums may be waived at either Fund's discretion. See 'Purchase of Shares.' If
shareholders reduce their total investment in shares of either Fund to less than
$10,000, their investment will be subject to mandatory redemption. See
'Redemption of Shares -- Mandatory Redemption.' Each Fund is one of several
series of the Company, an open-end management investment company organized as a
Maryland corporation.

 
UBS BOND FUND
 
The Bond Fund is designed for investors seeking a higher total return from a
portfolio of debt securities issued by domestic and foreign companies than that
generally available from a portfolio of short-term obligations in exchange for
some risk of capital. The net asset value of shares of the Bond Fund fluctuates
with changes in the value of the investments in the Bond Portfolio. See
'Investment Objectives and Policies -- Quality Information.'
 
The Bond Portfolio may make various types of investments in seeking its
objective. Among the permissible investments for the Bond Portfolio are bonds
and debt instruments of domestic and foreign companies. The Bond Portfolio may
also invest in futures contracts, options, forward contracts on foreign
currencies and certain privately placed securities. For further information
about these investments and related investment techniques, see 'Investment
Objectives and Policies' discussed below.
 
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 that generally available from a portfolio of
higher-rated obligations in exchange for assuming additional risk of capital.
The High Yield Bond 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 net asset value
of shares of the High Yield Bond Fund fluctuates with changes in the value of
the investments in the High Yield Bond Portfolio. See 'Investment Objectives and
Policies -- Quality Information.'
 
The High Yield Bond Portfolio may make various types of investments in seeking
its objectives. Among the permissible investments for the High Yield Bond
Portfolio are high-yielding, lower-rated bonds and debt instruments of domestic
and foreign companies commonly known as 'junk bonds.' Investments of this type
are subject to a greater risk of loss of principal and nonpayment of interest.
Investors should carefully assess the risks associated with an investment in the
High Yield Bond Fund. The High Yield Bond Fund is designed for investors willing
to assume additional risk in return for above-average income potential. See
'Additional Investment Information and Risk Factors.'
 
The High Yield Bond 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.

The following table illustrates that Fund investors incur no shareholder
transaction expenses: their investments in the Funds are subject only to the
operating expenses set forth below for the Funds and their respective Portfolios
as a percentage of average daily net assets of such Fund. The Directors believe
that the aggregate per share expenses of each Fund and its corresponding
Portfolio will be approximately equal to and may be less than the expenses that
such Fund would incur if it retained the services of an investment adviser and
invested its assets directly in portfolio securities. Expenses for each Fund and
Portfolio are discussed below under the headings 'Management,' 'Expenses' and
'Shareholder Services.'

*   Expenses are expressed as a percentage of a Fund's average daily net assets
and are based on the expenses actually incurred during the fiscal year ended
December 31, 1997 for the Bond Fund, and expected to be incurred during the
fiscal year ending December 31, 1998, for the High Yield Bond Fund, after any
applicable fee waivers and expense reimbursements. Without such fee waivers and
expense reimbursements, Total Operating Expenses were equal, on an annual basis,
to 2.34% of the Bond Fund's average daily net assets and are expected to be
equal, on an annual basis, to 2.81% of the High Yield Bond Fund's average daily
net assets. See 'Management.'

 
**  The Adviser has agreed to waive fees and reimburse each Fund and its
respective Portfolio for any of its respective operating expenses to the extent
that each such Fund's total operating expenses (including its share of its
respective Portfolio's expenses) exceed, on an annual basis, 0.80% of the Bond
Fund's average daily net assets and 0.90% of the High Yield Bond 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 either Fund.
 
If there were no fee waiver in effect, the Bond Portfolio and the High Yield
Bond Portfolio's advisory fees would each be equal, on an annual basis, to 0.45%
of the average daily net assets of each such Portfolio. 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 Funds, (b) as
custodian of the Funds and the Portfolios and (c) as transfer agent of the

(ii) IBT Trust & Custodial Services (Ireland) LMTD ('IBT Ireland') under an
Administration Agreement with the Portfolios, and
 
(iii) Eligible Institutions providing shareholder services under various

HISTORICAL PERFORMANCE OF COMPARABLE DISCRETIONARY ACCOUNTS -- BOND FUND. The
following table sets forth (i) the composite average annual total returns for
the one, three, five and ten year periods ended December 31, 1997, for all
discretionary accounts described below that have been managed for at least one
full quarter by UBSAM, (ii) the average annual total return for the Bond Fund
for the period April 2, 1996 (commencement of operations) through December 31,
1996, and the year ended December 31, 1997, and (iii) the average annual total
return during the same periods for the Lehman Government/Corporate Intermediate
Bond Index (the 'Lehman 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 Bond Portfolio. While the Bond
Portfolio will be managed by the Adviser, the management of the Bond Portfolio
will be substantially the same as by UBSAM and will be carried out by personnel
who performed these services for the discretionary accounts at UBSAM, who will
be employed by the Adviser for this purpose. The composite total returns for
such accounts have been adjusted to deduct all of the Bond Fund's annual total
operating expenses of 0.80% 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 Bond 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 Bond Portfolio and should not be viewed as a prediction of
future performance of the Bond Portfolio. The Lehman Index is an unmanaged
composite of intermediate duration consisting of publicly-issued, fixed-rate,
non-convertible, domestic bonds. The total returns of the Lehman 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 Funds seek to achieve their investment objectives by
investing all of their investable assets in their respective Portfolios. The
Portfolios are separate investment companies with the same investment objectives
as their respective Funds. The investment objective of a Fund and a Portfolio
may be changed only with the approval of the holders of a majority of the
outstanding voting securities of such Fund or a majority of the investors in
such Portfolio, respectively, after 30 days' prior notice.
 
In addition to selling an interest in a Portfolio to a Fund, each 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 a Fund and will pay a proportionate share of the Portfolio's
expenses. However, other entities investing in the Portfolios may sell shares of
their own fund using a different pricing structure than a Fund's. Such different
pricing structures may result in differences in returns experienced by investors
in other funds that invest in the Portfolios. Such differences in returns are
not uncommon and are present in other mutual fund structures. Information
concerning other holders of interests in the Portfolios is available from
Investors Bank at (888) UBS-FUND.
 
Each Fund may withdraw its investment in its 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 Funds 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 a Portfolio's investment objective, policies or restrictions,
or a failure by a Fund's shareholders to approve a change in a Portfolio's
investment objective or restrictions, may require a Fund to withdraw its
investment in the Portfolio. Any such withdrawal could result in an in-kind
distribution of portfolio securities (as opposed to a cash distribution) by a
Portfolio to a Fund. In no event, however, will securities which are not readily
marketable exceed 15% of the total value of such in-kind distribution. Such a
distribution may result in a 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 Portfolios may be materially affected by the
actions of larger funds investing in the Portfolios. For example, if a large
fund withdraws from a Portfolio, the remaining funds may subsequently experience
higher pro rata operating expenses, thereby lowering returns. Additionally,
because a 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 a Portfolio could have effective voting control of its operations.
Except as permitted by the SEC, whenever a Fund is requested to vote on matters
pertaining to a Portfolio, the Company will hold a
 
                                      -8-

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 Fund
shareholders who do, in fact, vote.

restrictions, see 'Investment Objectives and Policies,' 'Additional Investment
Information and Risk Factors' and 'Investment Restrictions.' For more

INVESTMENT OBJECTIVES AND POLICIES
 
The investment objective of each Fund and its respective Portfolio is described
below, together with the policies each employs to seek to achieve its objective.
Additional information about the investment policies of each Fund and its
respective Portfolio appears in the SAI under 'Investment Objectives and
Policies.' Each Fund seeks to achieve its objective by investing all of its
investable assets in its respective Portfolio, which has the same investment
objective as the Fund. There can be no assurance that the investment objectives
of the Funds or the Portfolios will be achieved.
 
UBS BOND FUND AND BOND PORTFOLIO
 
The objective of the Bond Portfolio is to provide a high total return from a
portfolio of debt securities issued by domestic and foreign companies,
consistent with moderate risk of capital and maintenance of liquidity. Total
return will consist of realized and unrealized capital gains and losses plus net
income. Although the net asset value of the Bond Portfolio will fluctuate, the
Bond Portfolio attempts to preserve the value of its investments to the extent
consistent with its investment objective.
 
The Bond Fund is designed for investors who seek a total return over time that
is higher than that generally available from a portfolio of shorter-term
obligations while recognizing the greater price fluctuation of longer-term
instruments. The Bond Fund may also be a convenient way to add fixed income
exposure to diversify an investor's existing portfolio.
 
The Adviser actively manages the Bond Portfolio's duration (defined below), the
allocation of securities across market sectors and the selection of specific
securities within sectors. Based on fundamental economic and capital markets
research, the Adviser adjusts the duration of the Bond Portfolio in light of
market conditions and the 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 Adviser also
actively allocates the Bond Portfolio's assets among broad sectors of the fixed
income market including, but not limited to, U.S. Government and agency
securities, corporate securities, private placements, asset-backed securities
and mortgage related securities. The Adviser intends to identify and purchase
specific securities that it believes are undervalued using 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 Adviser intends to keep at least 65% of the Bond 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' and 'Government Obligations' below.
 

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 one percentage point change in yield will result
in a 4% change in price in the opposite direction. The Bond Portfolio's
benchmark is the Lehman Government Corporate Intermediate Bond Index, which
currently has a duration of approximately 3.31 years. The Bond Portfolio intends
to have a duration between 0.5 years shorter and 0.5 years longer than its
benchmark. The maturities of the Bond

 
                                      -9-
 <PAGE>
<PAGE>
Portfolio's individual securities may vary widely from its duration, however,
and may be as long as 30 years.
 
The Bond Portfolio intends to manage its securities actively in pursuit of its
investment objective. Bond Portfolio transactions are undertaken principally to
accomplish the Bond Portfolio's objective in relation to expected movements in
the general level of interest rates, but the Bond Portfolio may also engage in
short-term trading consistent with its objective. To the extent the Bond
Portfolio engages in short-term trading, it may incur increased transaction
costs. For the period April 2, 1996 (commencement of operations) to December 31,
1996, and for the year ended December 31, 1997, the portfolio turnover rate for
the Bond Portfolio was 100% and 129%, respectively.
 
UBS HIGH YIELD BOND FUND AND HIGH YIELD BOND PORTFOLIO
 
The Adviser is responsible for supervising the management of the High Yield Bond
Portfolio's investments. Consistent with these duties, the Adviser has entered
into a Sub-Advisory Agreement with UBSAM, whereby UBSAM is primarily responsible
for the day-to-day investment decisions for the High Yield Bond Portfolio. The
Adviser is solely responsible for paying UBSAM for these services. UBSAM is an
affiliate of the Adviser.
 
The primary objective of the High Yield Bond Portfolio is to provide high
current income from a portfolio of higher-yielding, lower-rated debt securities
issued by domestic and foreign companies. The High Yield Bond 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 High Yield Bond 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 High Yield Bond 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 UBSAM 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 High Yield
Bond Portfolio may invest up to 25% of its assets in the securities of foreign
issuers.
 
The High Yield Bond 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 High Yield Bond Fund may also be a convenient way to add high yield bond
exposure to diversify an investor's existing portfolio.
 

UBSAM intends to identify and purchase specific securities that will constitute
a diversified portfolio. In selecting securities, UBSAM 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, UBSAM intends to keep at least 65% of the High Yield Bond
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, UBSAM may also manage the High Yield Bond Portfolio's
duration (defined under 'UBS Bond Fund and Bond Portfolio' above), and the
allocation of securities across market sectors. Based on fundamental economic
and capital markets research, UBSAM may adjust the duration of the High Yield
Bond Portfolio in light of market conditions and UBSAM'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. UBSAM also actively allocates the High Yield Bond 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.
 

The High Yield Bond Portfolio's benchmark is the Merrill Index, which currently
has a duration of approximately 4.26 years. The High Yield Bond Portfolio
intends to have a duration between 3 years and

 
                                      -10-
 <PAGE>
<PAGE>
8 years. The maturities of the High Yield Bond Portfolio's individual securities
may vary widely from its duration, however, and may be as long as 30 years.
 

   
The High Yield Bond Portfolio intends to manage its securities actively in
pursuit of its investment objective. High Yield Bond Portfolio transactions are
undertaken principally to accomplish the High Yield Bond Portfolio's objective
in relation to expected movements in the general level of interest rates, but
the High Yield Bond Portfolio may also engage in short-term trading consistent
with its objective. See 'Portfolio Transactions' in the SAI. To the extent the
High Yield Bond Portfolio engages in short-term trading, it may incur increased
transaction costs. For the period September 30, 1997 (commencement of
operations) to December 31, 1997, the portfolio turnover rate for the High Yield
Bond Portfolio was 80%.

    

CORPORATE SECURITIES. The Portfolios 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 Portfolios 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 pay interest to the holders thereof, federal
income tax law requires the Funds 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 Funds. See 'Dividends and Distributions.'

 

The Bond Portfolio does not intend to invest in common stock but may invest to a
limited degree in convertible debt or preferred stocks. The High Yield Bond
Portfolio may invest to a limited degree in common stock, convertible debt or
preferred stocks to the extent consistent with its investment objective. The
Portfolios also may purchase nonpublicly offered debt securities. See
'Additional Investment Information and Risk Factors -- Illiquid Investments;
Privately Placed and Other Unregistered Securities.'

 
GOVERNMENT OBLIGATIONS. The Bond Portfolio may invest in obligations issued or
guaranteed by the U.S. Government and backed by the full faith and credit of the
United States. These securities include Treasury securities, obligations of the
Government National Mortgage Association ('GNMA Certificates'), the Farmers Home
Administration and the Export Import Bank. GNMA Certificates are mortgage-backed
securities that evidence an undivided interest in mortgage pools. These
securities are subject to more rapid repayment than their stated maturity would
indicate because prepayments of principal on mortgages in the pool are passed
through to the holder of the securities. During periods of declining interest
rates, prepayments of mortgages in the pool can be expected to increase. The
pass-through of these prepayments would have the effect of reducing the Bond
Portfolio's positions in these securities and requiring the Bond Portfolio to
reinvest the prepayments at interest rates prevailing at the time of
reinvestment. The Bond Portfolio may also invest in obligations issued or
guaranteed by U.S. Government agencies or instrumentalities where the Bond
Portfolio must look principally to the issuing or guaranteeing agency for
ultimate repayment; some examples of agencies or instrumentalities issuing these
obligations are the Federal Farm Credit System, the Federal Home Loan Banks and
the Federal National Mortgage Association. Although these governmental issuers
are responsible for payments on their obligations, they do not guarantee their
market value. See 'Investment Objectives and Policies' in the SAI for a more
detailed discussion of the Bond Portfolio's investments in government
securities.
 
The Bond Portfolio may also invest in municipal obligations, which may be
general obligations of the issuer or payable only from specific revenue sources.
However, the Bond Portfolio will invest only in municipal obligations that have
been issued on a taxable basis or have an attractive yield excluding tax
considerations. In addition, the Bond Portfolio may invest in debt securities of
foreign governments and
 
                                      -11-
 <PAGE>
<PAGE>
governmental entities. See 'Additional Investment Information and Risk Factors'
for further information on foreign investments.
 
MONEY MARKET INSTRUMENTS. The Portfolios may purchase money market instruments
to invest temporary cash balances or to maintain liquidity to meet withdrawals.
However, the Portfolios 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
Portfolios include obligations of the U.S. Government and its agencies and
instrumentalities, other debt securities, commercial paper, bank obligations and
repurchase agreements. For more detailed information about these money market
investments, see 'Investment Objectives and Policies' in the SAI.
 

FOREIGN SECURITIES. The Portfolios do not expect to invest more than 25% of
their total assets in securities principally traded in foreign markets. The High
Yield Bond 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. If the Portfolios invest in non-U.S. dollar denominated
securities, it may hedge its foreign currency exposure. See 'Foreign Investment
Information' and 'Foreign Currency Exchange Transactions' under 'Additional
Investment Information and Risk Factors.'

 
QUALITY INFORMATION. It is a current policy of the Bond Portfolio that under
normal circumstances at least 65% of its investment in bonds will consist of
securities that are rated at least A by Moody's or S&P or that are unrated and
in the Adviser's opinion are of comparable quality. Up to 30% of the Bond
Portfolio's bonds may consist of debt securities rated Baa or better by Moody's
or BBB or better by S&P or are unrated and in the Adviser's opinion are of
comparable quality. Up to 5% of the Bond Portfolio's bonds may be invested in
debt securities that are rated Ba or better by Moody's or BB or better by S&P or
are unrated and in the Adviser's opinion are of comparable quality. Securities
rated Baa by Moody's or BBB by S&P are considered investment grade, but have
some speculative characteristics. Securities rated Ba by Moody's or BB by S&P
are below investment grade and considered to be speculative with regard to
payment of interest and principal. These standards must be satisfied at the time
an investment is made. If the quality of the investment later declines, the Bond
Portfolio may continue to hold the investment.
 

Higher yields are generally available from securities in the lower rating
categories of Moody's Investors Service, Inc. ('Moody's') and Standard & Poor's
Ratings Group ('S&P'), including securities rated Baa or 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 High Yield
Bond 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 UBSAM determines to be of
comparable quality. If, subsequent to the High Yield Bond Portfolio's purchase
of a security, the security's rating is reduced by a rating service, the High
Yield Bond Portfolio will not necessarily dispose of that security. UBSAM will,
however, monitor the investment to determine whether continued investment in the
security will assist in meeting the High Yield Bond Fund's investment objective.

 
The Portfolios may also purchase obligations on a when-issued or delayed
delivery basis, enter into repurchase and reverse repurchase agreements, loan
their 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. The
Bond Portfolio may engage in mortgage dollar roll transactions. 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 High Yield Bond 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 High Yield
Bond Fund's net asset value.
 
                                      -12-
 <PAGE>
<PAGE>
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 UBSAM to be comparable, (i)
will likely have some quality and protective characteristics that, in the
judgment of the rating organization and/or UBSAM, 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 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
High Yield Bond Portfolio more volatile and could limit the High Yield Bond
Portfolio's ability to sell its securities at prices approximating the values
the High Yield Bond 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 High Yield Bond Portfolio to establish the fair market value of these
securities and calculate the High Yield Bond 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. Each Portfolio may invest in convertible securities. The
convertible securities in which the Portfolios 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. Each 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
Portfolios 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 Portfolios 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 Portfolios will rely on the other party to consummate the
transaction; if the other party fails to do so, the Portfolios may be
disadvantaged. It is the current policy of the Portfolios 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. Each 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, a 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
Portfolios always receive 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. Each Portfolio is also permitted to enter into
reverse repurchase agreements. In a reverse repurchase agreement, a Portfolio
sells a security and agrees to repurchase it at a
 
                                      -13-
 <PAGE>
<PAGE>
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 a 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
Portfolios may lend their securities. The Portfolios may lend their 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 Portfolios 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 Portfolios and its respective
investors. The Portfolios may pay reasonable finders' and custodial fees in
connection with a loan. In addition, the Portfolios will consider all the 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 of the Company, the Trust, the Portfolios, or the Adviser,
Administrator or Distributor, unless otherwise permitted by applicable law.
 

TEMPORARY DEFENSIVE INVESTMENTS. Under unusual market circumstances, the
Portfolios 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 Funds' net investment income and dividend yield will decrease
accordingly. The Portfolios cannot predict when, if ever, they might use these
defensive investments, to what extent they might utilize these investments or
for how long they might hold these types of investments.

 
FOREIGN INVESTMENT INFORMATION. The Portfolios may invest in foreign securities.
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 a 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 a
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 Portfolios 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 Portfolios' 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
 
                                      -14-
 <PAGE>
<PAGE>
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 Portfolios may invest in securities of foreign issuers directly or in the
form of American Depository Receipts ('ADRs') and European Depository Receipts
('EDRs'). The High Yield Bond Portfolio also may invest in Global Depository
Receipts ('GDRs'). 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 Portfolios may buy and sell
securities and receive interest and dividends in currencies other than the U.S.
dollar, the Portfolios may, from time-to-time, enter into foreign currency
exchange transactions. The Portfolios 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 Portfolios 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 a
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 Portfolios 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 Portfolios 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 Portfolios for currency or
futures options increase the Portfolios' transaction costs. Similarly, the cost
of a 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
Portfolios 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
Portfolios 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 (the 'Securities Act'). Subject to those non-
fundamental policy limitations, the Portfolios 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 Portfolios. 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 Portfolios pay for illiquid securities or
receive 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 Portfolios 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 Portfolios are permitted to enter into the
futures and options transactions described below. These instruments are commonly
known as derivatives.
 
The Portfolios 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 Portfolios 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 Portfolios may use these techniques to manage their 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 a 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 a 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 Portfolios 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 they could have obtained by purchasing
the relevant securities and will not use futures contracts or options to
leverage their 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 a Portfolio's overall
strategy in a manner deemed appropriate to the Adviser and consistent with a
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.
 
A 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 a Portfolio's return. While a Portfolio's use of these
instruments may reduce certain risks associated with owning its portfolio
securities, these techniques themselves entail
 
                                      -16-
 <PAGE>
<PAGE>
certain other risks. If the Adviser applies a strategy at an inappropriate time
or judges market conditions or trends incorrectly, such strategies may lower a
Portfolio's return. Certain strategies limit a Portfolio's opportunity to
realize gains as well as limiting its exposure to losses. The Portfolios 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 Portfolios
will incur costs, including commissions and premiums, in connection with these
transactions and these transactions could significantly increase a Portfolio's
turnover rate.
 
The Portfolios 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.
 
The Commodity Exchange Act prohibits U.S. persons, such as the Portfolios, from
buying or selling certain foreign futures contracts or options on such
contracts. Accordingly, the Portfolio will not engage in foreign futures or
options transactions unless the contracts in question may lawfully be purchased
and sold by U.S. persons in accordance with applicable Commodity Futures Trading
Commission ('CFTC') regulations or CFTC staff advisories, interpretations and no
action letters.
 
In addition, in order to assure that the Portfolios will not be considered a
'commodity pool' for purposes of CFTC rules, the Portfolios 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, a 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, a 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. A
Portfolio may terminate its position in a put option it has purchased by
allowing it to expire or by exercising the option. A 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, a Portfolio will lose
the entire premium it paid. If a Portfolio exercises a put option on a security,
it will sell the instrument underlying the option at the strike price. If a
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 a 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. A 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 a 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.
 
                                      -17-
 <PAGE>
<PAGE>
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 a 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 Portfolios are 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 Portfolios 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. A
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 a Portfolio may
not be able to close out an option position that it has previously entered into.
When a 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 a 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 a
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 a 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 a 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 a 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 Portfolios, 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 a Portfolio's current or
anticipated investments. The Portfolios 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
 
                                      -18-
 <PAGE>
<PAGE>
that the options or futures position will not track the performance of the
Portfolio's other investments. The Portfolios 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 Portfolios buy or sell a futures contract they will be
required to deposit 'initial margin' in a segregated account with the 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 Portfolios 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 Portfolios to close out their futures
positions. Until it closes out a futures position, the Portfolios 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 Portfolios, the Portfolios 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 Portfolios.
 
COVER -- SEGREGATED ACCOUNTS. The Portfolios 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 a Portfolio's assets could impede portfolio management or a
Portfolio's ability to meet redemption requests or other current obligations.
 
For further information about the Portfolios' 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 objectives of each Fund and its respective 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 such Fund or such
Portfolio, respectively. Each Fund has the same investment restrictions as its
corresponding Portfolio, except that each Fund may invest all of its investable
assets in another open-end investment company with the same investment objective
and restrictions (such as its corresponding Portfolio). References below to each
Portfolio's investment restrictions also include the Funds' investment
restrictions.
 
As a diversified investment company, 75% of the total assets of each Portfolio
are subject to the following fundamental limitations: (a) a 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) a Portfolio may not own more than 10%
of the outstanding voting securities of any one issuer.
 
Each 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 establish each Portfolio's general policies, are responsible for the
overall management of the Trust, and review the actions of the Adviser, UBSAM,
the administrator and other service providers. Similarly, the Directors 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 each Board and the officers of the Trust and the Company
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 Trust and the Company are also employees of Investors Bank or
its affiliates.
 
ADVISER, SUB-ADVISER AND FUNDS SERVICES AGENT. The Company has not retained the
services of an investment adviser with respect to the Funds because the Funds
seek to achieve their investment objective by investing all of their investable
assets in their respective Portfolios. Each Portfolio has retained the services
of the Branch as investment adviser and the High Yield Bond Portfolio has
retained the services of UBSAM as investment sub-adviser. 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 United States.
 

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 December 31, 1997, the Bank (including its consolidated subsidiaries) had
total assets of $395.1 billion (unaudited) and shareholders' equity of $14.4
billion (unaudited). See 'Investment Adviser' in the SAI.

 

On December 8, 1997, the Bank and Swiss Bank Corporation ('Swiss Bank')
announced their intention to merge (the 'Merger Transaction') the Bank with
Swiss Bank to form a new company expected to be called UBS. In February, 1998,
the shareholders of UBS and Swiss Bank overwhelmingly approved the proposed
Merger Transaction. The Merger Transaction's completion is still subject to a
number of conditions, including the receipt of regulatory approvals.

 
The Adviser and UBSAM each provide investment advice and portfolio management to
the Portfolios. Subject to the supervision of the Trustees and the Adviser,
UBSAM makes the High Yield Bond Portfolio's day-to-day investment decisions,
arranges for the execution of portfolio transactions and generally manages the
High Yield Bond 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 Funds and the Portfolios 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 Funds and Portfolios 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 Funds and providing any resultant expense
reimbursement to the Funds.
 
The Branch provides its administrative services to the Funds pursuant to a Funds
Services Agreement between the Branch and the Company. The Branch does not
receive a fee from the Company or the Funds pursuant to the terms of the Funds
Services Agreement.

Under the Trust's Investment Advisory Agreement, the Bond Portfolio and the High
Yield Bond Portfolio each pay the Adviser a fee, calculated daily and payable
monthly, equal, on an annual basis, to 0.45% of the respective Portfolio's
average daily net assets. The Adviser has voluntarily agreed to waive its fees
and reimburse the Funds and the Portfolios for any of their direct and indirect
expenses to the extent that each Fund's total operating expenses (including its
share of its Portfolio's expenses) exceed, respectively, on an annual basis,
0.80% and 0.90% of the respective Fund's average daily net assets. The Adviser
may modify or discontinue this fee waiver and expense limitation at any time in
the future with 30 days' prior notice to a Fund. See 'Expenses.'
 

Pursuant to the Sub-Advisory Agreement between the Adviser and UBSAM, the
Adviser has agreed to pay UBSAM a fee, calculated daily and payable monthly,
equal, on an annual basis to 0.25% of the Fund's first $25 million of average
daily net assets, 0.20% of the next $25 million of such assets and 0.15% of such
assets in excess of $50 million. The Adviser is solely responsible for paying
UBSAM this fee.

 
PORTFOLIO MANAGERS. The Adviser and UBSAM each use a sophisticated, disciplined,
collaborative process for managing all asset classes.
 
The Adviser and UBSAM have advised mutual funds since 1996, but each has
considerable experience managing portfolios with similar investment objectives.
See 'Historical Performance of Comparable Discretionary Accounts.'
 

Ranji H. Nagaswami and Maud I. Welles are primarily responsible for the
day-to-day management and implementation of the Adviser's process for the Bond
Portfolio. Ms. Nagaswami, CFA, is also Managing Director and Head of Fixed
Income of UBSAM and has served as a portfolio manager of UBSAM since 1986. She

University. Ms. Nagaswami and Ms. Welles have eleven years and twelve years of
investment experience, respectively.

 

Kevin J. McCormick and Kurtis W. Krestinski are primarily responsible for the
day-to-day management and implementation of UBSAM's process for the High Yield
Bond Portfolio. Mr. McCormick has twelve years investment experience. Mr.
McCormick spent two years as a portfolio manager for UBSAM before leaving and
joining Wasserstein Perella Securities, where he spent one year. Mr. McCormick
rejoined UBSAM 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. Mr. Krestinski has four years investment
experience and has been a Vice President and Portfolio Manager of UBSAM since
1996. He also serves on the firm's Credit Committee. Previously, Mr. Krestinski

received an M.B.A. from Columbia Business School.

 
ADMINISTRATORS. The Portfolios and the Funds each employ IBT Ireland, a
subsidiary of 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 payable monthly, equal, on an annual
basis, to 0.065% of such 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 Funds on average daily net assets in excess of
$200 million.
 

For its services under the Administration Agreement, each Portfolio pays IBT
Ireland a fee, calculated daily and payable monthly, equal, on an annual basis,
to 0.07% of such Portfolio's first $100 million of average daily net assets and
0.05% of the 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

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

CUSTODIAN. Investors Bank serves as the custodian for the Portfolios and the
Funds and transfer and dividend disbursing agent for the Funds. 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 Funds, 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 Funds, 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 Adviser and Investors Bank, the Funds will be
responsible for other expenses, including litigation and extraordinary expenses.
The Adviser has voluntarily agreed to limit the total operating expenses of the
Bond Fund and the High Yield Bond Fund, excluding extraordinary expenses, to an
annual rate of 0.80% of the Bond Fund's average daily net assets and 0.90% of
the High Yield Bond Fund's average daily net assets. The Adviser may modify or
discontinue this voluntary expense limitation at any time in the future with 30
days' prior notice to the Funds.
 
The Portfolios 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 Company also reserves the right to determine the purchase
orders that it will accept and reserves the right to cease offering its shares
at any time. The shares of the Funds may be purchased only in those states where
they may be lawfully sold.
 
The minimum initial investment in either 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 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. For purposes of the minimum
investment requirements, the Funds may aggregate investments by related
shareholders. The investment minimums may be waived at either Fund's discretion.
 
No share certificates will be issued.
 
PURCHASE PRICE AND SETTLEMENT. Fund shares 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 First Fund.
 
                                      -22-
 <PAGE>
<PAGE>
Each 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 First Fund 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 as next determined on the day that the

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 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
 
                                      -23-

<PAGE>
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 a 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. The Funds may
suspend redemptions or postpone payments when the NYSE is closed or when trading
is restricted for any reason or under emergency circumstances as determined by
the SEC.
 
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 Funds 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 a Fund or the
Transfer Agent to employ such procedures may cause the Funds 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 a 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.

<PAGE>
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.
 
RETIREMENT PLANS
 
Each 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 Funds do not
currently act as sponsors 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 ((888) 326-3863).

 
DIVIDENDS AND DISTRIBUTIONS
 
Each Fund will declare daily, and pay monthly, dividends from its daily net
investment income. The Funds 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 such Fund.
 
Substantially all of a 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 Funds. Declared dividends and
distributions are payable on the payment date to shareholders of record on the
record date.
 
                                      -25-
 <PAGE>
<PAGE>
Dividends and capital gains distributions paid by the Funds 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 Funds reserve the right to discontinue, alter or limit the
automatic reinvestment privilege at any time.
 
NET ASSET VALUE
 
A Fund's net asset value per share equals the value of a 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 Funds and the Portfolios, 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.
 
Each 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
Funds 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
holidays: New Year's Day, Dr. Martin Luther King, Jr. 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 expect 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 nine 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 Cap Growth Fund Series; The UBS Small Cap Fund Series; The UBS Value
Equity Fund Series and The UBS Real Estate 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 Bond Fund Series and The UBS High Yield Bond Fund Series are offered
through this Prospectus.
 
Shareholders of a 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: UBS Bond Portfolio, UBS High Yield Bond Portfolio,
UBS Value Equity Portfolio, UBS International Equity Portfolio, UBS Small Cap
Portfolio, UBS Large Cap Growth Portfolio and UBS Real Estate Portfolio.
 
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 a Fund and other entities investing in a Portfolio (e.g.,
other investment companies, insurance company separate accounts and
 
                                      -26-
 <PAGE>
<PAGE>
common and commingled trust funds) will each be liable for all the obligations
of a Portfolio. However, the risk of a 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
 
Each Fund intends to annually qualify and elect to be treated 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. Each Portfolio intends to qualify as a
partnership for federal income tax purposes. As such, each Portfolio generally
should not be subject to tax. The status of a 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 investment income and 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. Distributions of net gains from certain foreign
currency transactions are taxable as ordinary income to shareholders of the
Funds 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 a 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 such 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 a 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 a 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 Funds 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 a 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
 
                                      -27-
 <PAGE>
<PAGE>
declared to non-corporate shareholders. Shareholders should be aware that, under
applicable regulations, a 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
 
Each 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 Funds 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 Lehman Indices, the Merrill Lynch Indices, Micropal Inc., Morningstar
Inc., Ibbotson Associates, Standard & Poor's 500 Composite Stock Price Index,
the Dow Jones Average, the Frank Russell Indices, the EAFE Index, the Financial
Times World Stock Index and other industry publications.

 
The Funds 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 Funds 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.

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 nine series, eight of which are described in this
Statement of Additional Information ('SAI'). These eight series (each a 'Fund'
and collectively, the 'Funds') consist of: UBS Bond Fund, UBS International
Equity Fund, UBS Institutional International Equity Fund, UBS Value Equity Fund,
UBS Small Cap Fund, UBS Large Cap Growth Fund, UBS High Yield Bond Fund and UBS
Real Estate 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 seven Portfolios: UBS Bond Portfolio; UBS
Value Equity Portfolio; UBS International Equity Portfolio; UBS Small Cap
Portfolio; UBS Large Cap Growth Portfolio; UBS High Yield Bond Portfolio and UBS
Real Estate Portfolio. UBS Bond Fund invests in UBS Bond Portfolio; UBS Value
Equity Fund invests in UBS Value 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; UBS High Yield
Bond Fund invests in UBS High Yield Bond Portfolio and UBS Real Estate Fund
invests in UBS Real Estate 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.
 
                                     SAI-1
 <PAGE>
<PAGE>
     UBS VALUE EQUITY FUND (the 'Value 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 volatility than is normally
available from common stock funds. The Value Equity Fund attempts to achieve its
investment objective by investing all of its investable assets in UBS Value
Equity Portfolio (the 'Value Equity Portfolio'), a series of the Trust having
the same investment objective as the Value Equity Fund.
 
     Under normal circumstances, at least 80% of the Value 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 Value 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 of 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 of 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
 
                                     SAI-2
 <PAGE>
<PAGE>
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 Cap Growth
Fund attempts to achieve its objective by investing all of its 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.
 
     UBS REAL ESTATE FUND (the 'Real Estate Fund') is designed for investors
seeking total return, consisting of long-term capital appreciation and current
income from a portfolio of equity securities of domestic and foreign real estate
companies. Because of the risks associated with common stock investments, the
Real Estate 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 Real Estate Fund seeks to achieve its investment objective by
investing all of its investable assets in UBS Real Estate Portfolio (the 'Real
Estate Portfolio'), a series of the Trust having the same investment objective
as the Real Estate Fund.
 
MONEY MARKET INSTRUMENTS
 
     As discussed in the Prospectuses, 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,
the High Yield Bond Fund and the Real Estate 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).
 
                                     SAI-3
 <PAGE>
<PAGE>

     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, High Yield Bond Fund and the Real Estate Fund, UBS Asset Management
(New York), Inc., ('UBSAM' or the 'Sub-Adviser') 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 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 Portfolios'
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 a 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
 
- ------------
     * Unless otherwise noted, references to the Adviser in the context of the
International Equity Portfolio, Small Cap Portfolio, Large Cap Growth Portfolio,
High Yield Bond Portfolio and the Real Estate Portfolio refer to the Adviser
and/or the Sub-Advisers, as appropriate.
 
                                     SAI-4
 <PAGE>
<PAGE>
without limitation corporate and foreign bonds, asset-backed securities and
other obligations described in the Prospectus or this SAI.
 

     As discussed in the relevant 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 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.
 
EQUITY INVESTMENTS
 

     As discussed in the Prospectuses, the Value Equity, International Equity,
Small Cap, Large Cap Growth and Real Estate 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.
 
     REAL ESTATE INVESTMENT TRUSTS ('REITS'). The Real Estate Portfolio's
investment in REITs presents certain further risks that are unique and in
addition to the risks associated with investing in the real estate industry.
Equity REITs may be affected by changes in the value of the underlying property
owned by the REITs, while mortgage REITs may be affected by the quality of any
credit extended. REITs are dependent on management skills, are not diversified
and are subject to the risks of financing projects. REITs whose underlying
assets include long-term health care properties, such as nursing, retirement and
assisted living facilities may be impacted by federal regulations concerning the
health care industry.
 
                                     SAI-5
 <PAGE>
<PAGE>
     REITs (especially mortgage REITs) are also subject to interest rate risks.
When interest rates decline, the value of a REIT's investment in fixed rate
obligations can be expected to rise. Conversely, when interest rates rise, the
value of a REIT's investment in fixed rate obligations can be expected to
decline. In contrast, as interest rates on adjustable rate mortgage loans are
reset periodically, yields on a REIT's investments in such loans will gradually
align themselves to reflect changes in market interest rates, causing the value
of such investments to fluctuate less dramatically in response to interest
fluctuations than would investments in fixed rate obligations.
 
     REITs may have limited financial resources, may trade less frequently and
in a limited volume, and may be subject to more abrupt or erratic price
movements than other securities.
 
FOREIGN INVESTMENTS
 
     The International Equity Portfolio makes substantial investments in
companies based in foreign countries. The Bond, High Yield Bond and Real Estate
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.
The Real Estate Portfolio may invest up to 20% of its assets in foreign
securities. 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, High Yield Bond and Real Estate
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, International Equity and
Real Estate 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).
 
                                     SAI-6
 <PAGE>
<PAGE>
     INVESTMENT COMPANY SECURITIES. Securities of other investment companies may
be acquired by each Portfolio 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 Portfolio's total assets will be invested in
the securities of any one investment company, (ii) not more than 10% of the
value of the Portfolio'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 Portfolio. Each
Portfolio, however, 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 Portfolios' 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 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 (except the Real Estate 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.'
 

     The Real Estate Portfolio is classified as a 'non-diversified' investment
company under the 1940 Act, which means that the Portfolio is not limited by the
above-mentioned requirements. However, the Portfolio intends to annually qualify
and elect to be treated as a regulated investment company ('RIC') for purposes
of the Internal Revenue Code of 1986, as amended (the 'Code'). In order to
qualify as a RIC, the Portfolio will have to meet certain requirements,
including asset diversification requirements. Under these asset diversification
requirements, the Portfolio will limit its investments so that, at the close of
each quarter of the taxable year: (i) not more than 25% of the Portfolio's total
assets (at market value) will be invested in the securities of a single issuer,
and (ii) with respect to 50% of its total assets (at market value), not more
than 5% of its total assets (at market value) will be invested in the securities
of a single issuer, and (iii) the Portfolio will not own more than 10% of the
outstanding voting securities of any single issuer. The Portfolio's investments
in securities issued by the U.S. Government, its agencies and instrumentalities
are not subject to these limitations.

 
     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 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
 
                                     SAI-8
 <PAGE>
<PAGE>

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.

 

     VALUE EQUITY, INTERNATIONAL EQUITY, SMALL CAP, LARGE CAP GROWTH AND REAL
ESTATE PORTFOLIOS. The Value Equity, International Equity, Small Cap, Large Cap
Growth and Real Estate 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 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

 
                                     SAI-9
 <PAGE>
<PAGE>
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 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
 
                                     SAI-10
 <PAGE>
<PAGE>
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 Directors 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 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
 
                                     SAI-11
 <PAGE>
<PAGE>
      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 (50% for the Real Estate Portfolio);
 
4.    (Except for the Real Estate Portfolio) 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 Value Equity
      Portfolio, the International Equity Portfolio, the Small Cap Portfolio nor
      the Large Cap Growth Portfolio may purchase or sell real estate mortgage
      loans. The Bond Portfolio, High Yield Bond Portfolio and the Real Estate
      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 Value Equity Portfolio, the Small Cap
      Portfolio, the Large Cap Growth Portfolio and the Real Estate 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;
 
 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;
 
                                     SAI-12
 <PAGE>
<PAGE>
 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 Funds have 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 (except the
       Real Estate 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, High Yield Bond
       Fund and Real Estate 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 organization 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, High Yield Bond
       Fund and Real Estate 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 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, High Yield Bond Fund and Real Estate 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

       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

       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

     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 December 31, 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 the
Branch, the Branch serves as the Portfolios' investment adviser. Pursuant to a
Sub-Advisory Agreement between the Branch and UBSII, UBSII serves as the
sub-adviser to the International Equity Portfolio. Pursuant to Sub-Advisory
Agreements between the Branch and UBSAM, UBSAM serves as the sub-adviser to the
Small Cap, Large Cap Growth, High Yield Bond and Real Estate Portfolios. 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. 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. UBSAM is a wholly-owned subsidiary of UBS Inc., whose parent
is the Bank. (The Adviser and the Sub-Adviser are collectively referred to as
the 'Advisers'.) Subject to the supervision of the Trustees, the Adviser (UBSII
in the case of the International Equity Portfolio and UBSAM in the case of the
Small Cap Portfolio, Large Cap Growth Portfolio, High Yield Bond Portfolio and
Real Estate Portfolio), 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, 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 since 1946. At December 31, 1997, the Bank (including its consolidated
subsidiaries) had total assets of $395.1 billion and shareholders' equity of
$14.4 billion.

 

     On December 8, 1997, the Bank and Swiss Bank Corporation ('Swiss Bank')
announced their intention to merge (the 'Merger Transaction') the Bank with
Swiss Bank to form a new company expected to be called United Bank of
Switzerland. In February, 1998, the shareholders of UBS and Swiss Bank
overwhelmingly approved the proposed Merger Transaction. The Merger
Transaction's completion is still subject to a number of conditions, including
the receipt of regulatory approvals.

 
     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.
 
     VALUE 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.
 

     REAL ESTATE FUND. The Sub-Adviser's portfolio manager has extensive
experience in analyzing and evaluating real estate companies and managing real
estate portfolios. Based on the investment objectives of the Fund, the
Sub-Adviser analyzes publicly-traded companies whose business is focused on the
development, ownership, management, and/or financing of real estate. Both REITs
as well as C-corporations are included in this group.

 
     The Sub-Advisers are registered investment advisers 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 fiscal year ended December 31, 1997, the advisory fees
for the Bond, Value Equity and International Equity Portfolios amounted to

Portfolio.

     The Adviser is solely responsible for paying this fee to UBSAM. For the
period December 22, 1997 to December 31, 1997, the Adviser paid $535 and $1,250
to UBSAM on behalf of the High Yield Bond and Small Cap Portfolios,
respectively. For the period December 29, 1997 to December 31, 1997, the Adviser
paid $100 to UBSAM on behalf of the Large Cap Growth Portfolio. The Real Estate
Portfolio had not commenced operations as of December 31, 1997.

 
     The Investment Advisory and Sub-Advisory Agreements for the Bond, Value
Equity and International Equity Portfolios will each continue in effect until
April 1998. The Investment Advisory and Sub-Advisory Agreements for the Small
Cap, Large Cap Growth and High Yield Bond Portfolios will each continue in
effect until September 1999, and the Investment Advisory and Sub-Advisory
Agreement for the Real Estate Portfolio will each continue in effect until
February 2000. Thereafter the agreements 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
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. Commencing on March 13, 1997, the Trust and the Company
employed IBT Trust & Custodial Services (Ireland) Limited ('IBT Ireland'), a
subsidiary of Investors Bank & Trust Company ('Investors Bank') and Investors

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

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

Portfolio and Fund had not commenced operations as of March 13, 1997.

 
     The Administration Agreements may be renewed or amended by the Directors or
Trustees, as applicable, without a 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,
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,

terms of the Distribution Agreement, but receives compensation from Investors
Bank.
 
CUSTODIAN
 
     Investors Bank (the 'Custodian'), whose principal offices are located at

transfer and dividend disbursing agent for the Funds and the Portfolios.
Pursuant to 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,
Toronto, Ontario M5X1C8, while its duties as the Funds' transfer agent and
dividend disbursing agent will be performed at its offices located at 200
Clarendon Street, Boston, Massachusetts 02116. Each Fund and Portfolio is
responsible for its proportionate share of the Company's and Trust's, as
applicable, transfer agency, custodial and dividend disbursement fees.
 
SHAREHOLDER SERVICES
 
     The Company (excluding UBS Institutional International Equity Fund) 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 shareholder services for these
investors, which include performing shareholder account administrative and
servicing functions, such as answering
 
                                     SAI-21
 <PAGE>
<PAGE>

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, Value Equity Fund and International
Equity Fund amounted to $7,632, $12,965 and $20,658, respectively, all of which
were waived. For the fiscal year ended December 31, 1997, the shareholder
service fee for the Bond Fund, Value Equity Fund and International Equity Fund
amounted to $23,536, $49,844 and $66,267, respectively, all of which were

Fund amounted to $1,730, all of which was waived. The Real Estate Fund had not
commenced operations as of December 31, 1997.

 
     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
 
                                     SAI-22
 <PAGE>
<PAGE>
the affected Fund. For additional information regarding waivers or expense
subsidies, see 'Management' in the Prospectuses.
 
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
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 its 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
(usually 4:00 p.m. EST, unless trading on the NYSE is suspended at an earlier
time) 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, Dr.
Martin Luther King, Jr. 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 Value Equity, Small Cap, Large Cap Growth, International
Equity and Real Estate 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-
 
                                     SAI-24

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 Prospectuses.
 
     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 Prospectuses.
 
     TOTAL RETURN QUOTATIONS. As required by SEC regulations, the average annual
total return of the Bond, High Yield Bond, Value Equity, Small Cap, Large Cap
Growth, International Equity, Institutional International Equity and Real Estate
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
 
                                     SAI-25

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 Morgan Stanley Indices,
Merrill Lynch Indices, 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. For the fiscal year ended
December 31, 1997, the portfolio turnover rate for the Bond Portfolio was 129%.
For the period September 30, 1997 (commencement of operations) through December
31, 1997, the portfolio turnover rate for the High Yield Bond Portfolio was 80%.

 

     In connection with portfolio transactions for the Value Equity, Small Cap,
Large Cap Growth, International Equity and Real Estate 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 Real Estate Portfolio is
expected to be under 100%. For the fiscal year ended December 31, 1997, the
portfolio turnover rate for the Value Equity and International Equity Portfolios
was 47% and 26%, respectively. For the period September 30, 1997 (commencement
of operations) through December 31, 1997, the portfolio turnover rate for the
Small Cap Portfolio was 3%. For the period October 14, 1997 (commencement of
operations) through December 31, 1997, the portfolio turnover rate for the Large
Cap Growth Portfolio was 6%. The Real Estate Portfolio had not commenced
operations as of December 31, 1997.

 
     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
 
                                     SAI-26
 <PAGE>
<PAGE>

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 fiscal year ended December 31, 1997, the Trust paid brokerage
commissions on behalf of the Value Equity and International Equity Portfolios in
the amount of $58,581 and $129,250, respectively. For the period September 30,
1997 (commencement of operations) through December 31, 1997, the Trust paid
brokerage commissions on behalf of the Small Cap Portfolio in the amount of
$30,680. For the period October 14, 1997 (commencement of operations) through
December 31, 1997, the Trust paid brokerage commissions on behalf of the Large
Cap Growth Portfolio in the amount of $18,270. The Real Estate Portfolio had not
commenced operations as of December 31, 1997.

 
     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 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 nine
series: The UBS Bond Fund Series; The UBS Tax Exempt Bond Fund Series; The UBS
Value Equity Fund Series; The UBS Institutional International Equity Fund
Series; The UBS International Equity Fund Series; The UBS High Yield Bond Fund
Series;
 
                                     SAI-27
 <PAGE>
<PAGE>
The UBS Small Cap Fund Series; The UBS Large Cap Growth Fund Series and The UBS
Real Estate 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
nine 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, seven
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 intends to annually qualify and elect to be treated 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; and (b) 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.
 
                                     SAI-28
 <PAGE>
<PAGE>
     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.
 
     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 Prospectuses. 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
 
                                     SAI-29
 <PAGE>
<PAGE>
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 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, 1997
- --------------------------------------------------------------------------------
 
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 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. At December
31, 1997, the Company included six other funds, UBS International Equity Fund,
UBS Value Equity Fund, UBS Institutional International Equity Fund, UBS High
Yield Bond Fund, UBS Small Cap Fund and UBS Large Cap Growth Fund. These
financial statements relate only to the Fund.
 
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. At December 31,
1997, certain shares of the Fund were held by UBS or its affiliates on behalf of
its clients. Three shareholders, individually owning greater than 10% of the
shares of the Fund, collectively held 35.4% at December 31, 1997.
 
Investors Bank & Trust Company ('IBT') serves as the Fund's administrator and
First Fund Distributors, Inc. ('FFDI') serves as the Fund's distributor. Union
Bank of Switzerland, New York Branch ('UBS') serves as the funds 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
(18.0% at December 31, 1997). Valuation of securities by the Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements.
 
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. At December 31, 1997, the Fund had a capital loss carryforward of
$20,238 which will expire in 2005. 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 year ended December 31, 1997, the Fund increased accumulated undistributed
net investment income by $19,502, decreased accumulated net realized loss on
securities and foreign currency by $14,463 and decreased paid-in-capital by
$5,039. 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 approximately $107,000 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 IBT, FFDI 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
by made fairly. Expenses directly attributable to the Fund are charged directly
to the Fund.
 
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

the Fund for expenses totaling $98,781 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 UBS Private
Investor Funds, Inc.) at December 31, 1997, the results of its operations for
the year then ended and the changes in its net assets and the financial
highlights for the year then ended and 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 audits. We conducted our
audits 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
audits provide a reasonable basis for the opinion expressed above.

UBS Bond Portfolio
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
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. At December 31,
1997, all of the beneficial interests in the Portfolio were held by UBS Bond
Fund and UBS Bond Fund, Ltd.
 
The investment adviser of the Portfolio is Union Bank of Switzerland, New York
Branch ('UBS'). Investors Fund Services (Ireland) Limited ('IBT Ireland') acts
as the Portfolio's administrator.
 
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 preparation of its financial statements:
 
A. INVESTMENT VALUATION -- Debt securities with remaining maturities of more
than 60 days are normally valued by a pricing service approved by the
Portfolio's 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 period-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 value
at the close of the period. 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 period-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.
 
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 period-end to credit loss in the event of 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. 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 approximately $30,000 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 IBT Ireland. 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 year ended December 31, 1997,
the investment advisory fee amounted to $272,781. UBS voluntarily agreed to
waive $151,544 of this amount.
 
B. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Trust, effective March 13, 1997, IBT Ireland 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 IBT
Ireland an administrative services fee, accrued daily and payable monthly, at an
annual rate of 0.07% of the Portfolio's first $100 million average daily net
assets and 0.05% of the Portfolio's average daily net assets in excess of $100
million. Prior to March 13, 1997, Signature Financial Group (Grand Cayman), Ltd.
('SFG') provided overall administrative services and general office facilities
to the Portfolio and the Trust. As compensation for such services, the Portfolio
had agreed to pay SFG an administrative services fee, accrued daily and paid
monthly, at an annual rate of 0.05% of the Portfolio's average daily net assets.
For the year ended December 31, 1997, the administrative services fee amounted
to $39,647.
 
4. PURCHASES AND SALES OF INVESTMENTS
For the year ended December 31, 1997, purchases and sales of investment
securities, excluding short-term investments, were as follows:

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 UBS Investor Portfolios Trust)
at December 31, 1997, the results of its operations for the year then ended and
the changes in its net assets and the financial highlights for the year then
ended and for the period April 2, 1996 (commencement of operations) through
December 31, 1996, in conformity with accounting principles generally accepted
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 audits. We conducted our audits of these
financial statements in accordance with auditing standards generally accepted 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
audits, which included confirmation of securities at December 31, 1997 by
correspondence with the custodian and brokers, and the application of
alternative auditing procedures where confirmations from brokers were not
received, provide a reasonable basis for the opinion expressed above.

UBS Value Equity Fund
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
1. GENERAL
 
UBS Value Equity Fund (the 'Fund'), formerly known as the UBS U.S. Equity Fund,
is a diversified, no-load mutual fund registered under the Investment Company
Act of 1940. 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. At December 31, 1997, the Company included six
other funds, UBS Bond Fund, UBS International Equity Fund, UBS Institutional
International Equity Fund, UBS High Yield Bond Fund, UBS Small Cap Fund and UBS
Large Cap Growth Fund. These financial statements relate only to the Fund.
 
The Fund seeks to achieve its investment objective by investing substantially
all of its investable assets in the UBS Value 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. At December 31,
1997, certain shares of the Fund were held by UBS or its affiliates on behalf of
its clients.
 
Investors Bank & Trust Company ('IBT') serves as the Fund's administrator and
First Fund Distributors, Inc. ('FFDI') serves as the Fund's distributor. Union
Bank of Switzerland, New York Branch ('UBS') serves as the funds 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
(48.2% at December 31, 1997). Valuation of securities by the Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements.
 
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. For the year
ended December 31, 1997, the

Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
Fund increased accumulated undistributed net investment income by $13,242 and
decreased paid-in-capital by $13,242. 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 approximately $107,500 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 IBT, FFDI 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
by made fairly. Expenses directly attributable to the Fund are charged directly
to the Fund.
 
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES
 
A. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Company, effective March 13, 1997, IBT provides overall administrative
services and general office facilities. As compensation for such services, the
Company has agreed to pay IBT a fee, accrued daily and payable monthly, at an
annual rate of 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. IBT does not
receive a fee on average daily net assets in excess of $200 million. Prior to
March 13, 1997, Signature Broker-Dealer Services, Inc. ('Signature') provided
overall administrative services and general office facilities. As compensation
for such services, the Company had agreed to pay Signature a fee, accrued daily
and paid 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 did not receive a fee on average daily net assets in excess of
$200 million. For the year ended December 31, 1997, the administrative services
fee amounted to $12,531.
 
B. DISTRIBUTION AGREEMENT -- Under the terms of a Distribution Agreement,
effective March 13, 1997, FFDI serves as the distributor of Fund shares. FFDI
does not receive any fees from the Fund for services provided pursuant to this
agreement. Prior to March 13, 1997, Signature served as the distributor of Fund
shares. Signature did not receive any additional fees for services provided as
the distributor.
 
C. SHAREHOLDER SERVICING AGREEMENT -- The Fund has entered into a Shareholder
Servicing 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 year ended December 31, 1997, the
shareholder service fee amounted to $49,844, all of which was waived.
 
D. FUNDS SERVICES AGREEMENT -- Under the terms of a Funds 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. For the period from January 1, 1997
through June 5, 1997, the Fund's total operating expenses were limited to an
annual rate of 0.90% of the Fund's average daily net assets. Effective June 6,
1997, this expense limitation was increased to 1.00% of the Fund's average daily
net assets. For the year ended December 31, 1997, UBS reimbursed the Fund for
expenses totaling $52,377 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 Value Equity Fund (the 'Fund') (one of the funds constituting UBS
Private Investor Funds, Inc.) at December 31, 1997, the results of its
operations for the year then ended and the changes in its net assets and the
financial highlights for the year then ended and 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 audits. We conducted our
audits 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
audits provide a reasonable basis for the opinion expressed above.

UBS Value Equity Portfolio
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
1. GENERAL
UBS Value Equity Portfolio (the 'Portfolio'), formerly known as the UBS U.S.
Equity 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. At December 31, 1997, all of the
beneficial interests in the Portfolio were held by UBS Value Equity Fund and UBS
Value Equity Fund, Ltd.
 
The investment adviser of the Portfolio is Union Bank of Switzerland, New York
Branch ('UBS'). Investors Fund Services (Ireland) Limited ('IBT Ireland') acts
as the Portfolio's administrator.
 
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.
 
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.
 
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 approximately $30,000 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 IBT Ireland. 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 0.60% of
the Portfolio's average daily net assets. For the year ended December 31, 1997,
UBS voluntarily agreed to waive a portion of its advisory fee. Such waiver
amounted to $160,330.

B. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Trust, effective March 13, 1997, IBT Ireland 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 IBT
Ireland an administrative services fee, accrued daily and payable monthly, at an
annual rate of 0.07% of the Portfolio's first $100 million average daily net
assets and 0.05% of the Portfolio's average daily net assets in excess of $100
million. Prior to March 13, 1997, Signature Financial Group (Grand Cayman), Ltd.
('SFG') provided overall administrative services and general office facilities
to the Portfolio and the Trust. As compensation for such services, the Portfolio
had agreed to pay SFG an administrative services fee, accrued daily and paid
monthly, at an annual rate of 0.05% of the Portfolio's average daily net assets.
For the year ended December 31, 1997, the administrative services fee amounted
to $27,257.
 
4. PURCHASES AND SALES OF INVESTMENTS
For the year ended December 31, 1997, purchases and sales of investment
securities, excluding short-term investments, aggregated $35,758,058 and
$18,403,738, respectively.

UBS Value 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 Value Equity Portfolio (the
'Portfolio') (one of the portfolios constituting UBS Investor Portfolios Trust)
at December 31, 1997, the results of its operations for the year then ended and
the changes in its net assets and the financial highlights for the year ended
December 31, 1997 and for the period April 2, 1996 (commencement of operations)
through December 31, 1996, in conformity with accounting principles generally
accepted 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 audits. We conducted our
audits of these financial statements in accordance with auditing standards
generally accepted 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 audits, which included confirmation of securities at December
31, 1997 by correspondence with the custodian and brokers, and the application
of alternative auditing procedures where confirmations from brokers were not
received, provide a reasonable basis for the opinion expressed above.

UBS International Equity Fund
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
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 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. At
December 31, 1997, the Company included six other funds, UBS Bond Fund, UBS
Value Equity Fund, UBS Institutional International Equity Fund, UBS High Yield
Bond Fund, UBS Small Cap Fund and UBS Large Cap Growth Fund. These financial
statements relate only to the Fund.
 
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. At December
31, 1997, certain shares of the Fund were held by UBS or its affiliates on
behalf of its clients.
 
Investors Bank & Trust Company ('IBT') serves as the Fund's administrator and
First Fund Distributors, Inc. ('FFDI') serves as the Fund's distributor. Union
Bank of Switzerland, New York Branch ('UBS') serves as the funds 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
(44.5% at December 31, 1997). Valuation of securities by the Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements.
 
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, 1997, the Fund decreased accumulated
undistributed net investment income by $13,766, increased accumulated
undistributed net realized gains by $25,116 and decreased paid-in-capital by
$11,350. 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 approximately $107,500 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 IBT, FFDI 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
by made fairly. Expenses directly attributable to the Fund are charged directly
to the Fund.
 
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES
 
A. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Company, effective March 13, 1997, IBT provides overall administrative
services and general office facilities. As compensation for such services, the
Company has agreed to pay IBT a fee, accrued daily and payable monthly, at an
annual rate of 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. IBT does not
receive a fee on average daily net assets in excess of $200 million. Prior to
March 13, 1997, Signature Broker-Dealer Services, Inc. ('Signature') provided
overall administrative services and general office facilities. As compensation
for such services, the Company had agreed to pay Signature a fee, accrued daily
and paid 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 did not receive a fee on average daily net assets in excess of
$200 million. For the year ended December 31, 1997, the administrative services
fee amounted to $16,199.
 
B. DISTRIBUTION AGREEMENT -- Under the terms of a Distribution Agreement
effective March 13, 1997, FFDI serves as the distributor of Fund shares. FFDI
does not receive any fees from the Fund for services provided pursuant to this
agreement. Prior to March 13, 1997, Signature served as the distributor of Fund
shares. Signature did not receive any additional fees for services provided as
the distributor.
 
C. SHAREHOLDER SERVICING AGREEMENT -- The Fund has entered into a Shareholder
Servicing 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 year ended December 31, 1997, the
shareholder service fee amounted to $66,267, all of which was waived.
 
D. FUNDS SERVICES AGREEMENT -- Under the terms of a Funds 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 REIMBURSEMENT -- 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. For the period from January 1, 1997
through April 14, 1997, the Fund's total operating expenses were limited to an
annual rate of 0.95% of the Fund's average daily net assets. Effective April 15,
1997, this expense limitation was increased to an annual rate of 1.40% of the
Fund's average daily net assets. For the year ended December 31, 1997, UBS
reimbursed the Fund for expenses totaling $70,945 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

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

UBS International Equity Portfolio
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
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. At
December 31, 1997, all of the beneficial interests in the Portfolio were held by
UBS International Equity Fund, UBS Institutional International Equity Fund and
UBS International Equity Fund, Ltd.
 
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. Investors Fund Services (Ireland) Limited ('IBT
Ireland') acts as the Portfolio's administrator.
 
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.
 
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').
 
Trading in securities on most foreign exchanges and over-the-counter market 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 period-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 value
at the close of the period. 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 period-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.

 <PAGE>
<PAGE>
UBS International Equity Portfolio
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
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 period-end to credit loss in the event of the
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 approximately $40,000 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, UBSII and IBT Ireland. 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
pay UBSII a fee, accrued daily and payable monthly, at an annual rate of 0.75%
of the Portfolio's first $20 million average daily net assets, 0.50% of the next
$30 million average daily net assets and 0.40% of the Portfolio's average daily
net assets in excess of $50 million. For the year ended December 31, 1997, the
investment advisory fee amounted to $428,213. UBS voluntarily agreed to waive
$176,323 of this amount.
 
B. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Trust, effective March 13, 1997, IBT Ireland 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 IBT
Ireland an administrative services fee, accrued daily and payable monthly, at an
annual rate of 0.07% of the Portfolio's first $100 million average daily net
assets and 0.05% of the Portfolio's average daily net assets in excess of $100
million. Prior to March 13, 1997, Signature Financial Group (Grand Cayman), Ltd.
('SFG') provided overall administrative services and general office

facilities to the Portfolio and the Trust. As compensation for such services,
the Portfolio had agreed to pay SFG an administrative services fee, accrued
daily and paid monthly, at an annual rate of 0.05% of the Portfolio's average
daily net assets. For the year ended December 31, 1997, the administrative
services fee amounted to $33,324.
 
4. PURCHASES AND SALES OF INVESTMENTS
For the year ended December 31, 1997, purchases and sales of investment
securities, excluding short-term investments, aggregated to $30,831,633 and
$11,714,524, respectively.

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 UBS Investor
Portfolios Trust) at December 31, 1997, the results of its operations for the
year then ended and the changes in its net assets and the financial highlights
for the year then ended and for the period April 2, 1996 (commencement of
operations) through December 31, 1996, in conformity with accounting principles
generally accepted 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 audits. We conducted our
audits of these financial statements in accordance with auditing standards
generally accepted 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 audits, which included confirmation of securities at December
31, 1997 by correspondence with the custodian and brokers, and the application
of alternative auditing procedures where confirmations from brokers were not
received, provide a reasonable basis for the opinion expressed above.

UBS Institutional International Equity Fund
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
1. GENERAL
 
UBS Institutional International Equity Fund (the 'Fund') is a diversified,
no-load mutual fund registered under the Investment Company Act of 1940. 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. At December 31, 1997, the Company included six other funds,
UBS Bond Fund, UBS Value Equity Fund, UBS International Equity Fund, UBS High
Yield Bond Fund, UBS Small Cap Fund and UBS Large Cap Growth Fund. These
financial statements relate only to the Fund.
 
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. At December
31, 1997, certain shares of the Fund were held by UBS or its affiliates on
behalf of its clients. One shareholder owned 100% of the shares of the Fund at
December 31, 1997.
 
Investors Bank & Trust Company ('IBT') serves as the Fund's administrator and
First Fund Distributors, Inc. ('FFDI') serves as the Fund's distributor. Union
Bank of Switzerland, New York Branch ('UBS') serves as the funds 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
(25.4% at December 31, 1997). Valuation of securities by the Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements.
 
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 amount 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

Notes to Financial Statements

- --------------------------------------------------------------------------------
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 year ended December 31, 1997, the Fund
decreased accumulated undistributed net investment income by $9,467, increased
accumulated undistributed net realized gains by $9,732 and decreased
paid-in-capital by $265. 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 approximately $27,000 have been deferred
and are being amortized on a straight line basis over five years from the Fund's
commencement of operations (April 14, 1997).
 
F. OTHER -- The Fund bears all costs of its operations other than expenses
specifically assumed by IBT, FFDI 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
by made fairly. Expenses directly attributable to the Fund are charged directly
to the Fund.
 
3. AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES
A. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Company, IBT provides overall administrative services and general
office facilities. As compensation for such services, the Company has agreed to
pay IBT a fee, accrued daily and payable monthly, at an annual rate of 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. IBT does not receive a fee on average
daily net assets in excess of $200 million. For the period April 14, 1997
(commencement of operations) through December 31, 1997, the administrative

To the Board of Directors
and Shareholder of

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

constituting UBS Private Investor Funds, Inc.) at December 31, 1997, and the
results of its operations, the changes in its net assets and the financial
highlights for the period April 14, 1997 (commencement of operations) through
December 31, 1997, 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 Small Cap Fund
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
1. GENERAL
UBS Small Cap Fund (the 'Fund') is a diversified, no-load mutual fund registered
under the Investment Company Act of 1940. 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. At December
31, 1997, the Company included six other funds, UBS Bond Fund, UBS Value Equity
Fund, UBS Institutional International Equity Fund, UBS High Yield Bond Fund, UBS
International Equity Fund and UBS Large Cap Growth Fund. These financial
statements relate only to the Fund.
 
The Fund seeks to achieve its investment objective by investing substantially
all of its investable assets in the UBS Small Cap 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. At December 31,
1997, certain shares of the Fund were held by UBS or its affiliates on behalf of
its clients. One shareholder owned 19.7% of the shares of the Fund at December
31, 1997.
 
Investors Bank & Trust Company ('IBT') serves as the Fund's administrator and
First Fund Distributors, Inc. ('FFDI') serves as the Fund's distributor. Union
Bank of Switzerland, New York Branch ('UBS') serves as the funds services agent
to the Fund.
 
The financial statements of the Portfolio, including its Schedule of
Investments, are include 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
(44.2% at December 31, 1997). Valuation of securities by the Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements.
 
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. For the period
ended December 31, 1997,

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 Small Cap Fund (the 'Fund') (one of the funds constituting UBS Private
Investor Funds, Inc.) at December 31, 1997, and the results of its operations,
the changes in its net assets and the financial highlights for the period
September 30, 1997 (commencement of operations) through December 31, 1997, 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.

    income to average net assets by 0.09% (annualized). The annualization of
    these ratios is affected by the fact that the Investment Advisory Agreement

    without compensation.

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 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.
 
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').
 
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 approximately $5,000 have been
deferred and are being amortized on a straight line basis over five years from
the Portfolio's commencement of operations (September 30, 1997).
 
E. OTHER -- The Portfolio bears all costs of its operations other than expenses
specifically assumed by UBS, UBSAM and IBT Ireland. 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 -- Effective December 22, 1997, the Portfolio
has retained the services of UBS as investment adviser and UBSAM as investment
sub-adviser. UBS and UBSAM were not entitled to receive any investment advisory
fee prior to the approval of the Investment Advisory Agreement and Investment
Sub-Advisory Agreement by the shareholders of the Fund. UBSAM 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

0.60% of the Portfolio's average daily net assets. UBS, in turn, has agreed to
pay UBSAM a fee, accrued daily and payable monthly, at an annual rate of 0.40%
of the Portfolio's first $25 million average daily net assets, 0.325% of the
Portfolio's next $25 million average daily net assets and 0.25% of the
Portfolio's average daily net assets in excess of $50 million. For the period
December 22, 1997 through December 31, 1997, the investment advisory fee
amounted to $4,233, all of which was waived.
 
B. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Trust, IBT Ireland 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 IBT Ireland an administrative services
fee, accrued daily and payable monthly, at an annual rate of 0.07% of the
Portfolio's first $100 million average daily net assets and 0.05% of the
Portfolio's average daily net assets in excess of $100 million. For the period
September 30, 1997 (commencement of operations) through December 31, 1997, the
administrative services fee amounted to $3,362.
 
4. PURCHASE AND SALES OF INVESTMENTS
For the period from September 30, 1997 (commencement of operations) through
December 31, 1997, purchases and sales of investment securities, excluding
short-term investments, aggregated $27,779,049 and $667,483, respectively.

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 Small Cap Portfolio (the
Portfolio') (one of the portfolios constituting the UBS Investor Portfolios
Trust) at December 31, 1997, and the results of its operations, the changes in
its net assets and the financial highlights for the period September 30, 1997
(commencement of operations) through December 31, 1997, in conformity with
accounting principles generally accepted 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 auditing standards generally accepted 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, 1997 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.

    Such fee waivers and expense reimbursements had the effect of reducing the
    ratio of expenses to average net assets and increasing the ratio of net
    investment income to average net assets by 7.54% (annualized). The
    annualization of these ratios is affected by the fact that the Investment

    until December 29, 1997. Prior to this date, investment advisory services
    were being provided without compensation.

UBS Large Cap Growth Fund
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
1. GENERAL
UBS Large Cap Growth Fund (the 'Fund') is a diversified, no-load mutual fund
registered under the Investment Company Act of 1940. 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. At
December 31, 1997, the Company included six other funds, UBS Bond Fund, UBS
Value Equity Fund, UBS Institutional International Equity Fund, UBS High Yield
Bond Fund, UBS Small Cap Fund and UBS International Equity Fund. These financial
statements relate only to the Fund.
 
The Fund seeks to achieve its investment objective by investing substantially
all of its investable assets in the UBS Large Cap Growth 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. At December
31, 1997, certain shares of the Fund were held by UBS or its affiliates on
behalf of its clients. Two shareholders, individually owning greater than 10% of
the shares of the Fund, collectively held 52.0% at December 31, 1997.
 
Investors Bank & Trust Company ('IBT') serves as the Fund's administrator and
First Fund Distributors, Inc. ('FFDI') serves as the Fund's distributor. Union
Bank of Switzerland, New York Branch ('UBS') serves as the funds 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
(21.6% at December 31, 1997). Valuation of securities by the Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements.
 
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. For
the period ended December 31, 1997, there were no permanent 'book/tax'
differences.
 
E. DEFERRED ORGANIZATION EXPENSES -- Expenses incurred by the Fund in connection
with its organization in the amount of approximately $20,000 have been deferred
and are being amortized on a straight line basis over five years from the Fund's
commencement of operations (October 14, 1997).
 
F. OTHER -- The Fund bears all costs of its operations other than expenses
specifically assumed by IBT, FFDI 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. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Company, IBT provides overall administrative services and general
office facilities. As compensation for such services, the Company has agreed to
pay IBT a fee, accrued daily and payable monthly, at an annual rate of 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. IBT does not receive a fee on average
daily net assets in excess of $200 million. For the period October 14, 1997
(commencement of operations) through December 31, 1997, the administrative
services fee amounted to $450.
 
B. DISTRIBUTION AGREEMENT -- Under the terms of a Distribution Agreement, FFDI
serves as the distributor of Fund shares. FFDI does not receive any fees from
the Fund for services provided pursuant to this agreement.
 
C. SHAREHOLDER SERVICING AGREEMENT -- The Fund has entered into a Shareholder
Servicing 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 October 14, 1997
(commencement of operations) through December 31, 1997, the shareholder service
fee amounted to $1,730, all of which was waived.
 
D. FUNDS SERVICES AGREEMENT -- Under the terms of a Funds 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 1.00% of the Fund's
average daily net assets. For the period October 14, 1997 (commencement of
operations) through December 31, 1997, UBS reimbursed the Fund for expenses
totaling $45,138 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.
 
4. CAPITAL SHARE TRANSACTIONS
At December 31, 1997 there were 500 million shares of the Company's common stock
authorized, of which 10 million shares were classified as common stock of the
Fund. Transactions in shares of the Fund during the period October 14, 1997
(commencement of operations) through December 31, 1997 were as follows:

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 Large Cap Growth Fund (the 'Fund') (one of the funds constituting UBS
Private Investor Funds, Inc.) at December 31, 1997, and the results of its
operations, the changes in its net assets and the financial highlights for the
period October 14, 1997 (commencement of operations) through December 31, 1997,
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 Large Cap Growth Portfolio
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
1. GENERAL
UBS Large Cap Growth 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. At
December 31, 1997, all of the beneficial interests in the Portfolio were held by
UBS Large Cap Growth Fund and UBS Large Cap Growth Fund, Ltd.
 
The investment adviser of the Portfolio is Union Bank of Switzerland, New York
Branch ('UBS'); UBS Asset Management (New York) Inc. ('UBSAM') is the
sub-adviser of the portfolio. Investors Fund Services (Ireland) Limited ('IBT
Ireland') acts as the Portfolio's administrator.
 
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.
 
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').
 
B. ACCOUNTING FOR INVESTMENTS -- Securities transactions are accounted for on
trade date. Realized gains and losses on securities 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 approximately $5,000 have been
deferred and are being amortized on a straight line basis over five years from
the Portfolio's commencement of operations (October 14, 1997).
 
E. OTHER -- The Portfolio bears all costs of its operations other than expenses
specifically assumed by UBS, UBSAM and IBT Ireland. 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 -- Effective December 29, 1997, the Portfolio
has retained the services of UBS as investment adviser and UBSAM as investment
sub-adviser. UBS and UBSAM were not entitled to receive any investment advisory
fee prior to the approval of the Investment Advisory Agreement and Investment
Sub-Advisory Agreement by the shareholders of the Fund. UBSAM 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
0.60% of the Portfolio's average daily net assets. UBS, in turn, has agreed to
pay UBSAM a fee, accrued daily and payable monthly, at an annual rate of 0.30%
of the Portfolio's first $25 million average daily net assets, 0.25% of the
Portfolio's next $25 million average daily net assets and 0.20% of the
Portfolio's average daily net assets in excess of $50 million. For the period
from December 29, 1997 through December 31, 1997, the investment advisory fee
amounted to $923, all of which was waived.
 
B. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Trust, IBT Ireland 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 IBT Ireland an administrative services
fee, accrued daily and payable monthly, at an annual rate of 0.07% of the
Portfolio's first $100 million average daily net assets and 0.05% of the
Portfolio's average daily net assets in excess of $100 million. For the period
ended December 31, 1997, the administrative services fee amounted to $2,096.
 
4. PURCHASES AND SALES OF INVESTMENTS
 
For the period October 14, 1997 (commencement of operations) through December
31, 1997, purchases and sales of investment securities, excluding short-term
investments, aggregated $18,325,865 and $795,811, respectively.

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 Large Cap Growth Portfolio
(the 'Portfolio') (one of the portfolios constituting UBS Investor Portfolios
Trust) at December 31, 1997, and the results of its operations, the changes in
its net assets and the financial highlights for the period October 14, 1997
(commencement of operations) through December 31, 1997, in conformity with
accounting principles generally accepted 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 auditing standards generally accepted 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, 1997 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.

UBS High Yield Bond Fund
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
1. GENERAL
UBS High Yield Bond Fund (the 'Fund') is a diversified, no-load mutual fund
registered under the Investment Company Act of 1940. 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. At
December 31, 1997, the Company included six other funds, UBS Bond Fund, UBS
Value Equity Fund, UBS Institutional International Equity Fund, UBS
International Equity Fund, UBS Small Cap Fund and UBS Large Cap Growth Fund.
These financial statements relate only to the Fund.
 
The Fund seeks to achieve its investment objective by investing substantially
all of its investable assets in the UBS High Yield 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. At December
31, 1997, certain shares of the Fund were held by UBS or its affiliates on
behalf of its clients. Three shareholders, individually owning greater than 10%
of the shares of the Fund, collectively held 52.1% at December 31, 1997.
 
Investors Bank & Trust Company ('IBT') serves as the Fund's administrator and
First Fund Distributors, Inc. ('FFDI') serves as the Fund's distributor. Union
Bank of Switzerland, New York Branch ('UBS') serves as the funds 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
(60.0% at December 31, 1997). Valuation of securities by the Portfolio is
discussed in Note 2A of the Portfolio's Notes to Financial Statements.
 
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
the period ended December 31, 1997, there were no permanent 'book/tax'
differences.
 
E. DEFERRED ORGANIZATION EXPENSES -- Expenses incurred by the Fund in connection
with its organization in the amount of approximately $20,000 have been deferred
and are being amortized on a straight line basis over five years from the Fund's
commencement of operations (September 30, 1997).
 
F. OTHER -- The Fund bears all costs of its operations other than expenses
specifically assumed by IBT, FFDI 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. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Company, IBT provides overall administrative services and general
office facilities. As compensation for such services, the Company has agreed to
pay IBT a fee, accrued daily and payable monthly, at an annual rate of 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. IBT does not receive a fee on average
daily net assets in excess of $200 million. For the period September 30, 1997
(commencement of operations) to December 31, 1997, the administrative services
fee amounted to $1,185.
 
B. DISTRIBUTION AGREEMENT -- Under the terms of a Distribution Agreement, FFDI
serves as the distributor of Fund shares. FFDI does not receive any fees from
the Fund for services provided pursuant to this agreement.
 
C. SHAREHOLDER SERVICING AGREEMENT -- The Fund has entered into a Shareholder
Servicing 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 September 30, 1997
(commencement of operations) to December 31, 1997, the shareholder service fee
amounted to $4,558, all of which was waived.
 
D. FUNDS SERVICES AGREEMENT -- Under the terms of a Funds 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 September 30, 1997 (commencement of
operations) to December 31, 1997, UBS reimbursed the Fund for expenses totaling
$50,088 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.
 
4. CAPITAL SHARE TRANSACTIONS
At December 31, 1997 there were 500 million shares of the Company's common stock
authorized, of which 10 million shares were classified as common stock of the
Fund. Transactions in shares of the Fund during the period September 30, 1997
(commencement of operations) through December 31, 1997 were as follows:

operations, the changes in its net assets and the financial highlights for the
period September 30, 1997 (commencement of operations) through December 31,
1997, 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

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 High Yield Bond Portfolio
Notes to Financial Statements
December 31, 1997
- --------------------------------------------------------------------------------
 
1. GENERAL
UBS High Yield 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. At
December 31, 1997, all of the beneficial interests in the Portfolio were held by
UBS High Yield Bond Fund and UBS High Yield Bond Fund, Ltd.
 
The investment adviser of the Portfolio is Union Bank of Switzerland, New York
Branch ('UBS'); UBS Asset Management (New York) Inc. ('UBSAM') is the
sub-advisor of the portfolio. Investors Fund Services (Ireland) Limited ('IBT
Ireland') acts as the Portfolio's administrator.
 
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 remaining maturities of more
than 60 days are normally valued by a pricing service approved by the
Portfolio's 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. 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.
 
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 approximately $5,000 have been
deferred and are being amortized on a straight line basis over five years from
the Portfolio's commencement of operations (September 30, 1997).
 
E. OTHER -- The Portfolio bears all costs of its operations other than expenses
specifically assumed by UBS, UBSAM and IBT Ireland. 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 -- Effective December 22, 1997, the Portfolio
has retained the services of UBS as investment adviser and UBSAM as investment
sub-advisor. UBS and UBSAM were not entitled to receive any investment advisory
fee prior to the approval of the Investment Advisory Agreement and Investment
Sub-Advisory Agreement by the Shareholders of the Fund. UBSAM 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
0.45% of the Portfolio's average daily net assets. UBS, in turn, has agreed to
pay UBSAM a fee, accrued daily and payable monthly, at an annual rate of 0.25%
of the Portfolio's first $25 million average daily net assets, 0.20% of the
Portfolio's next $25 million average daily net assets and 0.15% of the
Portfolio's average daily net assets in excess of $50 million. For the period
December 22, 1997 through December 31, 1997, the investment advisory fee
amounted to $1,611, all of which was waived.
 
B. ADMINISTRATION AGREEMENT -- Under the terms of an Administration Agreement
with the Trust, IBT Ireland 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 IBT Ireland an administrative services
fee, accrued daily and payable monthly, at an annual rate of 0.07% of the
Portfolio's first $100 million average daily net assets and 0.05% of the
Portfolio's average daily net assets in excess of $100 million. For the period
September 30, 1997 (commencement of operations) through December 31, 1997, the
administrative services fee amounted to $1,870.
 
4. PURCHASES AND SALES OF INVESTMENTS
For the period September 30, 1997 (commencement of operations) through December
31, 1997, purchases and sales of investment securities, excluding short-term
investments, were as follows:

UBS High Yield 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 High Yield Bond Portfolio
(the 'Portfolio') (one of the portfolios constituting UBS Investor Portfolios
Trust) at December 31, 1997, and the results of its operations, the changes in
its net assets and the financial highlights for the period September 30, 1997
(commencement of operations) through December 31, 1997, in conformity with
accounting principles generally accepted 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 auditing standards generally accepted 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, 1997 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.
